PROSPECTUS SUMMARY The following summary contains basic information about this Offering. It may not contain all the information that is important to you. We encourage you to read this entire document for an understanding of this Offering. The Company We are a leading domestic and international provider of wireless communications and broadcast transmission infrastructure and related services. Our business is to own, operate and manage wireless communications sites and broadcast transmission networks. In addition, we provide a full range of complementary services to our customers including (1) network design and site selection, (2) site acquisition, (3) site development and construction, (4) antenna installation and (5) network management and maintenance. As of September 30, 1998, we owned or managed 1,302 towers, including 548 towers in the United States and 754 towers in the United Kingdom. In addition, on October 8, 1998, we added 102 towers in the United Kingdom through our acquisition of Millennium Communications Limited. Assuming we had formed the proposed joint venture with Bell Atlantic Mobile (as described below under "Proposed Joint Venture"), as of September 30, 1998, we would have owned an additional 1,427 towers, including 117 towers that we currently manage. These 1,427 towers form a significant portion of Bell Atlantic Mobile's 850 MHz wireless communications network in the eastern and southwestern United States. As of September 30, 1998 --------------------------------- Total After Proposed Proposed CCIC Joint Venture Joint Venture ----- ------------- ------------- United States Towers...................................... 548 1,427(a) 1,858 Rooftops.................................... 81 -- 81 United Kingdom Towers...................................... 754 -- 754 Rooftops(b)................................. 54 -- 54 ----- ----- ----- 1,437 1,427(a) 2,747 ===== ===== ===== - -------- (a) Includes 117 towers we currently manage. See "Business--U.S. Operations-- Significant Contracts--Bell Atlantic Mobile". (b) The 54 revenue producing rooftop sites in the United Kingdom are occupied by our transmitters but are not available for leasing to our customers. Based on our industry position and experience, we believe that we are well positioned to continue to capitalize on global growth opportunities arising from: . the expansion of existing networks and the introduction of new networks in the wireless communications industry; . the consolidation of tower ownership generally, including the transfer of infrastructure ownership from major wireless communications carriers to independent infrastructure providers; . the ongoing privatization of state-run broadcast transmission networks around the world; and . the widespread introduction of digital transmission technology in the broadcasting industry. 1

Our Site Rental Business Our site rental business involves leasing antenna space to customers on towers and rooftops that we own or manage. We generally receive fees for installing a customer's equipment and antennas and also receive monthly rental payments under site leases that typically range in term from three to five years. The following is a list of our major site rental customers in the United States and the United Kingdom: United States United Kingdom ------------- -------------- Aerial Communications Cellnet AT&T Wireless National Transcommunications Limited Bell Atlantic Mobile One2One BellSouth Mobility Orange Personal Communications Motorola Vodafone Nextel PageNet Sprint PCS Our Broadcast Transmission Business Our broadcast transmission business includes both (1) the transmission of analog and digital television and radio broadcasts and (2) the construction of new broadcast towers that can hold multiple tenants. In the United Kingdom, we provide analog transmission services for two national television services, seven national radio services and 37 local radio stations through our network of 3,465 transmitters. We provide these services under long-term contracts with the British Broadcasting Corporation (the "BBC") and two national commercial radio companies. We also provide both the BBC and ONdigital (formerly known as British Digital Broadcasting Limited) with digital transmission services under long-term contracts. These two companies are the holders of 67% of the multiplexes for digital terrestrial television broadcasting throughout the United Kingdom. In the United States, we plan to build new multiple tenant broadcast towers in locations where the introduction of digital terrestrial television broadcasting will necessitate additional tower capacity to accommodate new digital and displaced analog transmission equipment. Our Expertise We have developed extensive expertise in our core site rental and broadcast transmission businesses. Further, our team of more than 300 engineers has substantial experience in providing end-to-end services, including (1) design of wireless communications and broadcast transmission networks, (2) radio frequency engineering, (3) site acquisition, (4) site development and construction and (5) antenna installation. We plan to leverage our technical expertise and operational experience to take advantage of the fundamental shift in strategy that is occurring among established wireless communications carriers relating to infrastructure ownership. Such carriers are beginning to seek to sell their wireless communications infrastructure to, or establish joint ventures with, experienced infrastructure providers that have the ability to manage networks. We believe that infrastructure providers with a proven track record of providing end-to-end services will be best positioned to successfully acquire access to such wireless communications infrastructure. Business Strategy Our objective is to become the premier global provider of wireless communications and broadcast transmission infrastructure and related services. Our experience in establishing and expanding our existing tower footprints, our experience in owning and operating both analog and digital transmission networks, our significant relationships with wireless communications carriers and broadcasters and our ability to offer customers our 2

in-house technical and operational expertise, uniquely position us to capitalize on global growth opportunities. The key elements of our business strategy are to: Maximize Utilization of Tower Capacity. We are seeking to increase the number of antenna leases on the towers and rooftops that we own or manage. We believe that many of our towers have significant capacity for additional antennas and that we can increase the number of tenants on these towers at a low incremental cost. Leverage Expertise of CCI and CTI Personnel to Implement Global Growth Strategy. We believe that our ability to manage wireless communications and broadcast transmission networks, including the transmission of signals, is an important competitive advantage in our pursuit of global growth opportunities. Partner with Wireless Communications Carriers to Assume Ownership of their Existing Towers. In addition to our proposed joint venture with Bell Atlantic Mobile, we will continue to seek to partner with other major wireless communications carriers in order to assume ownership of their towers directly or through joint ventures. Provide Build-to-Suit Towers for Wireless Communications Carriers and Broadcasters. As wireless communications carriers continue to expand and fill- in their service areas, they will require additional communications sites and will have to build new towers where co-location is not available. Similarly, the introduction of digital terrestrial television broadcasting in the United States will require the construction of new broadcast towers to accommodate new digital transmission equipment and analog transmission equipment displaced from existing towers. We are aggressively pursuing these build-to-suit opportunities. Acquire Existing Transmission Networks. Based on our experience with CTI, we are well positioned to acquire other state-owned analog and digital transmission networks when opportunities arise. We will consider acquiring wireless transmission networks as well as the associated wireless communications infrastructure. Capitalize on Management Experience. We have assembled and will continue to build a strong management team that has extensive experience in the tower industry and in the management of broadcast transmission networks. Proposed Joint Venture On December 8, 1998, we entered into an agreement (the "Formation Agreement") with Bell Atlantic Mobile ("BAM") to form a joint venture to own and operate a significant majority of BAM's towers. We would own approximately 62.3% of the joint venture and BAM and certain of its affiliates would own the other 37.7% along with a 0.001% interest in the joint venture's operating subsidiary. We intend to consolidate the joint venture's results of operations and financial condition with ours for financial reporting purposes. To form the proposed joint venture, we would contribute $250.0 million in cash and approximately 15.6 million shares of our common stock (valued at $197.0 million) to the joint venture. BAM and its affiliates would transfer approximately 1,427 towers along with related assets and liabilities to the joint venture. The joint venture would borrow $180.0 million under a committed $250.0 million revolving credit facility. The joint venture would also make a $380.0 million cash distribution to BAM. After making this distribution and paying fees and expenses related to its formation, the joint venture initially would have approximately $45.9 million of cash to fund its operations and pay costs and expenses associated with building new towers. 3

LOGO Upon the dissolution of the proposed joint venture, we would receive all the assets and liabilities of the joint venture other than the approximately 15.6 million shares of our common stock held by the joint venture. BAM would receive (1) the shares of our common stock and (2) a payment from us, equal to 14.0% of the fair market value of the assets and liabilities of the proposed joint venture other than our common stock, to be made in cash or shares of our common stock (as elected by us). BAM would continue to retain its 0.001% interest in the joint venture's operating subsidiary and would maintain most of its governance rights with respect to the operating subsidiary. See "Business-- Proposed Joint Venture--Operating Agreement". BAM may trigger the dissolution of the proposed joint venture at any time following the third anniversary of its formation and we may trigger the dissolution at any time following the fourth anniversary; however, if we trigger the dissolution prior to the seventh anniversary we may be required to make additional cash payments to BAM. We will manage the day-to-day operations of the proposed joint venture. The proposed joint venture will construct and own certain new towers that are needed by BAM's wireless communications business. In addition, the proposed joint venture will actively seek to add additional tenants, including wireless communications carriers other than BAM, to its towers in order to increase its revenues. The proposed joint venture will have regional offices that will be staffed primarily with our employees to perform marketing, operations and maintenance functions. A board of representatives, initially to be comprised of four representatives selected by us and two representatives selected by BAM, will oversee the proposed joint venture. Significant actions to be taken by the proposed joint venture will require the approval of the board of representatives including, in certain circumstances, the approval of representatives of both BAM and us. See "Business--The Proposed Joint Venture-- Operating Agreements". Concurrently with the formation of the proposed joint venture, BAM and the joint venture will enter into a master build-to-suit agreement (the "Build-to- Suit Agreement"). The proposed joint venture will be required to pay for and construct 500 new towers, and will have the right to pay for and construct an additional 200 new towers, in the general vicinity of locations selected by BAM. The selected locations are to be in areas where, in the judgment of BAM, no structures suitable for BAM's antennas exist. BAM would be the anchor tenant on these towers. Pursuant to a global lease agreement (the "Global Lease") with the proposed joint venture, BAM will lease antenna space on the towers transferred to the joint venture at an average monthly rent per tower of $1,850 and on each tower constructed under the Build-to-Suit Agreement at minimum rental rates ranging from $1,250 to $1,833 per month depending on the tower's location. See "Business--Proposed Joint Venture--Build-to-Suit Agreement" and "--Global Lease". Although we expect the proposed joint venture to be formed during the first quarter of 1999, the Formation Agreement is subject to a number of significant conditions. Therefore, we cannot guarantee you that we will form the proposed joint venture on the terms described in this document or at all. See "Risk Factors--The Proposed Joint Venture May Not Occur". Background Founded in 1994, we acquired 127 towers located in Texas, Colorado, New Mexico, Arizona, Oklahoma and Nevada from Pittencrieff Communications, Inc. in 1995. We subsequently continued to build our business through a variety of transactions, including the acquisition in 1996 of Motorola's SMR and microwave system in Puerto Rico, which included 15 communication sites; the purchase through a series of transactions in 1996 and 4

1997 of TEA Group Incorporated, a leading domestic and international site acquisition firm (the "TEA Acquisition"); and the purchase in February 1997 of a 34.3% ownership interest in CTI (the "CTI Investment"). In August 1997, we acquired the assets of Crown Communications (the "Crown Merger"), which included 61 owned towers and the exclusive right to lease antenna space on 147 other towers and rooftop sites, most of which were located in and around the greater Pittsburgh area. On October 31, 1997, we borrowed approximately $94.7 million (the "October Bank Financing") and privately placed $36.5 million of senior convertible preferred stock (the "Senior Convertible Preferred Stock") and warrants to purchase shares of our common stock. The proceeds of the October Bank Financing and the private placement of Senior Convertible Preferred Stock were used to repay a seller note issued in connection with the acquisition of the assets of Crown Communications, to repay loans outstanding under a credit agreement at Crown Communications and to pay related fees and expenses. We refer to the October Bank Financing, the private placement of the Senior Convertible Preferred Stock and the application of the proceeds collectively as the "October Refinancing". On November 20, 1997, we privately placed (the "1997 Notes Offering") $251.0 million principal amount at maturity ($150,010,150 initial accreted value) of our 10 5/8% Senior Discount Notes due 2007 (the "Notes"). The net proceeds to us from the 1997 Notes Offering were used to repay substantially all our outstanding indebtedness, including our borrowings in the October Bank Financing, to pay related fees and expenses and for general corporate purposes. We refer to the October Refinancing, the 1997 Notes Offering and the application of the net proceeds from the 1997 Notes Offering collectively as the "1997 Refinancing". On August 21, 1998, we increased our ownership interest in CTI to 80.0% by consummating a share exchange with certain shareholders of CTSH (the "Exchange"). The remaining 20.0% of CTSH's shares are owned by TdF (whose ultimate parent is France Telecom). Immediately prior to the Exchange, we converted all shares of our then existing preferred stock into shares of our common stock and reclassified our then existing common stock into shares of our common stock (the "Conversions"). We refer to the Exchange and the Conversions collectively as the "Roll-Up". At that time, we also raised $151,043,200 in an initial public offering of our Common Stock (the "IPO"). We intend to use the proceeds of the IPO to finance a portion of our investment in the proposed joint venture with BAM. ---------------- Our principal executive offices are located at 510 Bering Drive, Suite 500, Houston, Texas 77057, telephone (713) 570-3000. 5

The Offering Summary of Terms of the Exchange Offer The Exchange Offer relates to the exchange of up to $200,000,000 aggregate liquidation preference of our outstanding 12 3/4 Senior Exchangeable Preferred Stock due 2010 (the "old preferred stock") for up to an equal aggregate liquidation preference of our 12 3/4 Senior Exchangeable Preferred Stock due 2010, which has been registered under the Securities Act of 1933 (the "new preferred stock"). The shares of the new preferred stock will be our obligations as governed by the terms of the Certificate of Designations we filed on December 18, 1998 with the Secretary of State of the State of Delaware. The form and terms of the shares of the new preferred stock are identical in all material respects to the form and terms of the shares of the old preferred stock except: . that the shares of the new preferred stock have been registered under the Securities Act, . that the shares of the new preferred stock are not entitled to certain registration rights which are applicable to the shares of the old preferred stock under a registration rights agreement, and . for certain liquidated damages provisions. For more information, see "Description of Securities." The Exchange Offer.......... We are offering to exchange $1,000 liquidation preference of new preferred stock for each $1,000 liquidation preference of old preferred stock. As of the date of this document, $200,000,000 in aggregate liquidation preference of old preferred stock is outstanding. The old preferred stock was originally issued in a private placement. As a condition to the purchase of the old preferred stock, the initial purchasers required that we make a registered offer to exchange the old preferred stock for other securities substantially similar to the old preferred stock. We are making this Exchange Offer to satisfy this contractual obligation. Resale...................... Based on an interpretation by the staff of the Securities and Exchange Commission set forth in no-action letters issued to third parties, we believe that new preferred stock issued pursuant to the Exchange Offer in exchange for old preferred stock may be offered for resale, resold and otherwise transferred by you (unless you are an "affiliate" of the Company within the meaning of Rule 405 under the Securities Act of 1933, or a broker-dealer which acquired the old preferred stock directly from us) without compliance with the registration and prospectus delivery provisions of the Securities Act of 1933, provided that you are acquiring the new preferred stock in the ordinary course of your business and that you have not engaged in, do not intend to engage in, and have no arrangement or understanding with any person to participate in the distribution of the new preferred stock. Each participating broker-dealer that receives shares of new preferred stock for its own account pursuant to the Exchange Offer in exchange for shares of old preferred stock that were acquired as a result of market-making or other trading activity must acknowledge that it will deliver a prospectus in connection with any resale of the shares of new preferred stock. See "Plan of Distribution." 7

Any holder of old preferred stock who (i) is an affiliate of the Company, (ii) does not acquire new preferred stock in the ordinary course of its business, (iii) tenders in the Exchange Offer with the intention to participate, or for the purpose of participating, in a distribution of new preferred stock or (iv) is a broker-dealer that acquired the old preferred stock directly from the Company, must comply with the registration and prospectus delivery requirements of the Securities Act of 1933 in connection with the resale of the new preferred stock. Expiration Date............. 5:00 p.m., New York City time, on , 1999, (20 business days after effectiveness of the registration statement of which this Prospectus is a part), unless we extend the Exchange Offer, in which case the term "Expiration Date" means the latest date and time to which the Exchange Offer is extended.

If you wish to tender in the Exchange Offer on your own behalf, you must, prior to completing and executing the Letter of Transmittal and delivering your shares of old preferred stock, either make appropriate arrangements to register ownership of the shares of old preferred stock in your name or obtain a properly completed bond power from the person whose name your shares of old preferred stock are registered. The transfer of registered ownership may take considerable time. Withdrawal Rights........... Tenders may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date pursuant to the procedures described under "The Exchange Offer--Withdrawal of Tenders."

preferred stock for cash at a purchase price of 101% of the liquidation preference of such shares, together with all accumulated and unpaid dividends to the date of purchase. However, our repurchase of new preferred stock under these circumstances must comply with certain provisions of the indenture governing our outstanding senior notes. If we were unable to comply with those provisions and fail to repurchase new preferred stock, then holders of the new preferred stock would be entitled to certain voting rights. In addition, there can be no assurance that we will have sufficient funds to repurchase the new preferred stock in the event of a change of control or that our creditors will otherwise allow us to make the repurchase. See "Risk Factors--Repurchase of the Exchangeable Preferred Stock or the Exchange Debentures Upon a Change of Control". Ranking..................... The new preferred stock will rank (1) senior to all other classes of capital stock of the Company established after the issue date of the new preferred stock that do not expressly provide that they rank on a parity with the new preferred stock as to dividends and distributions upon the liquidation, winding up and dissolution of the Company and (2) on a parity with any class of capital stock established after the date of issuance of the new preferred stock the terms of which provide that such class or series will rank on a parity with the new preferred stock as to dividends and distributions upon the liquidation, winding up and dissolution of the Company. Our obligations with respect to the new preferred stock are subordinate and junior in right of payment to all our present and future indebtedness, including the Notes, and are effectively subordinate to all debt and liabilities (including trade payables) of our restricted and unrestricted subsidiaries. If we had completed the offering of the new preferred stock on September 30, 1998 and had applied the proceeds as intended, we would have had approximately $507.3 million of indebtedness and other liabilities including $343.3 million of indebtedness and other liabilities (including trade payable) of our subsidiaries. In addition, if we had also formed the proposed joint venture as of that date, we would have had approximately $687.3 million of indebtedness and other liabilities including $523.3 million of indebtedness and other liabilities (including trade payable) of our subsidiaries. Our creditors will have priority over the new preferred stock with respect to claims on our assets. See "Description of Securities-- Description of Senior Exchangeable Preferred Stock--Ranking." Certain Covenants........... We will issue the new preferred stock pursuant to the terms of the certificate of designations that we filed on December 18, 1998 and which became part of our certificate of incorporation. The 10

certificate of designations contains certain covenants that, among other things, limit our ability and the ability of certain of our subsidiaries to: . borrow money; . pay dividends on stock or purchase our capital stock; . make investments; and . sell assets or merge with or into other companies. These covenants are subject to important exceptions and qualifications which are described in "Description of Securities--Description of Senior Exchangeable Preferred Stock" under the heading "Certain Covenants." Voting Rights............... The new preferred stock will have no voting rights except as required by law and as specified in the certificate of designations. If we fail to meet our obligations under the covenants contained in the certificate of designations, the holders of the new preferred stock will be entitled to elect two additional members of our Board of Directors. Exchange Feature............ On any scheduled dividend payment date, we have the option to exchange all (but not less than all) of the shares of new preferred stock then outstanding for our 12 3/4% Senior Subordinated Exchange Debentures due 2010 (the "exchange debentures"). If we exercise our option to exchange, we will issue exchange debentures in an aggregate principal amount equal to the aggregate liquidation preference of the outstanding new preferred stock. The indenture governing our outstanding senior notes contains substantial restrictions on our ability to exchange new preferred stock for exchange debentures. See "Description of Securities--Description of Senior Exchangeable Preferred Stock--Exchange". Registration Rights and Liquidated Damages......... Holders of new preferred stock (except as described below) are not entitled to any registration rights with respect to the new preferred stock. Pursuant to a registration rights agreement, we agreed to file with the Commission within 60 days following the consummation of the offering a registration statement with respect to an offer to exchange the exchangeable preferred stock for a new series of our exchangeable preferred stock registered under the Securities Act, with terms substantially identical to the exchangeable preferred stock. We also agreed to use all commercially reasonable efforts to cause the registration statement to become effective within 150 days following consummation of the offering. If the exchange offer is not permitted by applicable law or is not consummated within the time periods specified in the registration rights agreement, we will be required to provide a shelf registration statement to cover 11

resales of shares of exchangeable preferred stock by holders of such shares. If we fail to satisfy these registration obligations, we will be obligated to pay liquidated damages to holders of the exchangeable preferred stock at the rates listed in the section "Description of Securities--Registration Rights and Liquidated Damages". The Exchange Debentures: Securities Offered.......... 12 3/4% Senior Subordinated Exchange Debentures due 2010 in an aggregate principal amount equal to the aggregate liquidation preference of the new preferred stock outstanding on the date of the exchange, plus such principal amount of additional exchange debentures as may be issued in lieu of cash interest. Maturity.................... December 15, 2010. Interest.................... At an annual fixed rate of 12 3/4%. We will pay interest on each June 15 and December 15 of each year, commencing on the first of these dates that occurs after the date of the exchange. On or before December 15, 2003, we have the option to pay interest in cash or in additional exchange debentures in an aggregate principal amount equal to the amount of such interest. After December 15, 2003, we will pay interest only in cash. Ranking..................... These exchange debentures are senior subordinated debts. They rank behind all of our current and future indebtedness (excluding trade payables) other than indebtedness that expressly provides that it is on a parity with or subordinated in right of payment to the exchange debentures. If we had completed the offering of the new preferred stock on September 30, 1998 and assuming that we exchanged the new preferred stock for exchange debentures on the same date, the exchange debentures: . would have been subordinate to $163.8 of senior debt of the Company; and . would have been effectively subordinate to the creditors, including trade creditors, of the Company's subsidiaries. Optional Redemption......... On or after December 15, 2003, we may redeem some or all of the exchange debentures at any time at the redemption prices (together with accrued and unpaid interest, if any, to the date of redemption) listed in the section "Description of Securities--Description of Senior Subordinated Exchange Debentures" under the heading "Optional Redemption". 12

In addition, before December 15, 2001, we may redeem up to 35% of the exchange debentures with the proceeds of certain public equity offerings or strategic equity investments at the price listed in the section "Description of Securities--Description of Senior Subordinated Exchange Debentures" under the heading "Optional Redemption". If we choose this option, we must redeem the exchange debentures within 60 days of receiving the proceeds. Mandatory Offer to Repurchase................. If we sell certain assets or experience specific kinds of changes of control, we must offer to repurchase the exchange debentures at the prices listed in the section "Description of Securities--Description of Senior Subordinated Exchange Debentures" under the heading "Repurchase at the Option of Holders". Basic Covenants of the Exchange Indenture......... If and when we issue the exchange debentures, we will issue them under an indenture with United States Trust Company of New York, as trustee. The indenture will, among other things, restrict our ability and the ability of certain of our subsidiaries to: .borrow money; .pay dividends on stock or purchase stock; .make investments; and .sell certain assets or merge with or into other companies. For more details, see the section "Description of Securities--Description of Senior Subordinated Exchange Debentures" under the heading "Certain Covenants". Registration Rights; Liquidated Damages......... If we exchange the old preferred stock into exchange debentures before we consummate a registered exchange offer for the old preferred stock, we will be required to make a registered exchange offer to all holders of exchange debentures. This registered exchange offer will give holders of exchange debentures the opportunity to exchange their debentures for new debentures that are substantially identical to the original debentures but have been registered under the Securities Act. If we fail to consummate the registered exchange offer within the required time frame, we will pay liquidated damages at the rates listed in the section "Description of Securities--Registration Rights and Liquidated Damages". We will continue to pay liquidated damages until we fulfill our registration obligations. 13

These expenses consist primarily of allocated compensation, benefits and overhead costs that are not directly related to the administration or management of existing towers. (b) Represents the aggregate number of sites of CCIC and its acquired businesses (including Crown), CTI and the Proposed JV for each period. As of September 30, 1998, the Company had contracts with 1,367 buildings in the United States to manage on behalf of such buildings the leasing of space for antennas on the rooftops of such buildings. A revenue producing rooftop represents a rooftop where the Company has arranged a lease of space on such rooftop and, as such, is receiving payments in respect of its management contract. The Company generally does not receive any payment for rooftops under management unless the Company actually leases space on such rooftops to third parties. As of September 30, 1998, the Company had 1,286 rooftop sites under management throughout the United States that were not revenue producing rooftops but were available for leasing to customers and, in the United Kingdom, the Company had 54 revenue producing rooftop sites that were occupied by the Company's transmitters but were not available for leasing to customers. (c) EBITDA is defined as operating income (loss) plus depreciation and amortization and non-cash compensation charges. Adjusted EBITDA is defined as the sum of (i) annualized site rental and broadcast transmission EBITDA before corporate development for the most recent calendar quarter and (ii) EBITDA, less site rental and broadcast transmission EBITDA before corporate development, for the most recent four calendar quarters. EBITDA and Adjusted EBITDA are presented as additional information because management believes them to be useful indicators of the Company's ability to meet debt service and capital expenditure requirements. They are not, however, intended as alternative measures of operating results or cash flow from operations (as determined in accordance with generally accepted accounting principles). Furthermore, the Company's measure of EBITDA may not be comparable to similarly titled measures of other companies. (d) For purposes of computing the ratio of earnings to fixed charges, earnings represent income (loss) before income taxes, minority interests and fixed charges. Fixed charges consist of interest expense, the interest component of operating leases and amortization of deferred financing costs. For the year ended December 31, 1997 and the nine months ended September 30, 1998, earnings were insufficient to cover fixed charges of the Consolidated Group by $61.4 million and $51.4 million, respectively. For the year ended December 31, 1997 and the nine months ended September 30, 1998, earnings were insufficient to cover fixed charges of the Restricted Group by $17.5 million and $29.1 million, respectively. (e) Total interest expense for the nine months ended September 30, 1998 includes amortization of deferred financing costs and discount of $13.0 million for CCIC, $0.6 million for CTI and $0.5 million for the Proposed JV. (f) Pro forma balances of cash and cash equivalents for the Restricted Group (i) exclude $105.2 million of proceeds from the Offering that are estimated to be contributed to the Proposed JV and (ii) include $15.8 million of proceeds from the Offering that the Company may elect to contribute to an Unrestricted Subsidiary concurrent with the consummation of the Offering. Upon consummation of the Offering in December 1998, the Company contributed $100.00 million of proceeds from the Offering to an Unrestricted Subsidiary. (g) Net debt represents total debt less cash and cash equivalents. 16

Summary Financial and Other Data of CTI The summary historical financial data for CTI, which was 34.3% owned by CCIC prior to the Roll-Up, presents (i) summary historical financial data of the BBC Home Service Transmission Business prior to its acquisition by CTI (the "Predecessor") for the year ended March 31, 1996 and the eleven and two months ended February 27, 1997, (ii) summary historical consolidated financial data of CTI after such acquisition for the one month ended March 31, 1997 and for the nine months ended December 31, 1997, and (iii) summary historical consolidated financial data of CTI for the eight months ended August 31, 1998. The summary historical financial data for the year ended March 31, 1996 and the eleven months ended February 27, 1997 have been derived from the financial statements of the Predecessor, which have been audited by KPMG, Chartered Accountants. The summary financial data for the one month ended March 31, 1997 and the nine months ended December 31, 1997 have been derived from the consolidated financial statements of CTI, which have been audited by KPMG, Chartered Accountants. The summary historical financial data for the two months ended February 27, 1997 have been derived from the unaudited financial statements of the Predecessor, and the summary historical financial data for the eight months ended August 31, 1998 have been derived from the unaudited consolidated financial statements of CTI, which include all adjustments that CTI considers necessary for a fair presentation of the financial position and results of operations for that period. The results of operations for the one month ended March 31, 1997, the nine months ended December 31, 1997 and the eight months ended August 31, 1998 are not necessarily indicative of the results of operations of CTI that may be expected for the entire year. CCIC acquired a majority ownership interest in CTI upon consummation of the Roll-Up in August 1998 and, as a result, historical financial data of CTI for the nine months ended September 30, 1998 is not presented. This information reflects financial data for CTI as a whole, is not limited to that portion of the financial data attributable to CCIC's percentage ownership of CTI prior to the Roll-Up and is not indicative of any distributions or dividends that CCIC might receive in the future. CTI is subject to significant restrictions on its ability to make dividends and distributions to CCIC. See "Risk Factors--Holding Company Structure; Dependence on Dividends to Meet Cash Requirements or Pay Dividends". The information set forth below should be read in conjunction with "Selected Financial and Other Data of CTI", "Management's Discussion and Analysis of Financial Condition and Results of Operations--Results of Operations--CTI" and the consolidated financial statements and the notes thereto of CTI included elsewhere in this document. 20

For the convenience of the reader, the information set forth above contains translations of pound sterling amounts into U.S. dollars at the Noon Buying Rate on September 30, 1998, of (Pounds)1.00 = $1.6995. No representation is made that the pound sterling amounts have been, could have been or could be converted into U.S. dollars at the rate indicated or any other rates. On November 30, 1998, the Noon Buying Rate was (Pounds)1.00 = $1.6485. (b) Corporate development expenses represent costs incurred in connection with acquisitions and development of new business initiatives. These expenses consist primarily of allocated compensation, benefits and overhead costs that are not directly related to the administration or management of existing towers. (c) As of August 31, 1998, CTI's 54 revenue producing rooftop sites were occupied by its transmitters but were not available for leasing to customers. (d) EBITDA is defined as operating income (loss) plus depreciation and amortization and non-cash compensation charges. EBITDA is presented as additional information because management believes it to be a useful indicator of CTI's ability to meet debt service and capital expenditure requirements. It is not, however, intended as an alternative measure of operating results or cash flow from operations (as determined in accordance with generally accepted accounting principles). Furthermore, CTI's measure of EBITDA may not be comparable to similarly titled measures of other companies. (e) For purposes of computing the ratio of earnings to fixed charges, earnings represent income (loss) before income taxes and fixed charges. Fixed charges consist of interest expense, the interest component of operating leases and amortization of deferred financing costs. For the nine months ended December 31, 1997, earnings were insufficient to cover fixed charges by (Pounds)2.5 million ($4.2 million). 22

RISK FACTORS This Prospectus contains forward-looking statements concerning our plans, strategies and prospective future financial performance. While we believe that the results of our plans, strategies and future financial performance are reasonable, our actual results could be significantly different due to certain risks. These risks are described below, and you should carefully consider them, as well as the other information included in this Prospectus, when evaluating your participation in the Exchange Offer. Consequences of Failure to Exchange Old Preferred Stock We will issue new preferred stock in exchange for the old preferred stock pursuant to the Exchange Offer only following the satisfaction of the procedures and conditions set forth in "The Exchange Offer--Procedures for Tendering." Such procedures and conditions include timely receipt by the Exchange Agent of such shares of old preferred stock, and of a properly completed and duly executed Letter of Transmittal. Shares of old preferred stock which you do not tender or we do not accept will, following the Exchange Offer, continue to be restricted securities and you may not offer or sell them except pursuant to an exemption from, or in a transaction not subject to, the Securities Act of 1933 and applicable state securities law. Any shares of old preferred stock tendered and exchanged in the Exchange Offer will reduce the aggregate principal amount of the old preferred stock outstanding. Following the Exchange Offer, if you did not tender your shares of old preferred stock you generally will not have any further registration rights, and such shares of old preferred stock will continue to be subject to certain transfer restrictions. Accordingly, the liquidity of the market for such shares of old preferred stock could be adversely affected. The shares of old preferred stock are currently eligible for sale pursuant to Rule 144A and Regulation S through the Private Offerings, Resale and Trading through Automated Linkages ("PORTAL") market of the National Association of Securities Dealers, Inc. Because we anticipate that most holders of old preferred stock will elect to exchange such shares of old preferred stock, we anticipate that the liquidity of the market for any shares of old preferred stock remaining after the consummation of the Exchange Offer may be substantially limited. Managing Integration and Growth Our ability to implement our growth strategy depends, in part, on our successes in integrating our acquisitions, investments, joint ventures and strategic alliances into our operations. We have grown significantly over the past two years through acquisitions and, as evidenced by our participation in the proposed joint venture, such growth is an important part of our business plan. The Crown Merger in August 1997 and the Roll-Up in August 1998 involved acquisitions of businesses that were significantly larger than our then existing business and represented a substantial increase in the scope of our business. Crown's revenues for fiscal 1996 were $19.4 million. In contrast, CCIC's revenues for fiscal 1996 were $6.2 million. Similarly, the Roll-Up resulted in our having majority ownership of CTI, which had consolidated revenues in the twelve months ended December 31, 1997 of (Pounds)76.0 million ($129.2 million). In addition, the acquisition of approximately 1,427 towers through the proposed joint venture will increase our current business considerably. Successful integration of these transactions will depend primarily on our ability to manage our combined operations and to integrate existing management with and into our management. We cannot guarantee that we will be able to successfully integrate these acquired businesses and assets or any future acquisitions into our business or implement our plans without delay. If we fail to do so it could have a material adverse effect on our financial condition and results of operations. We regularly evaluate potential acquisition and joint venture opportunities. Implementation of our acquisition strategy may impose significant strains on our management, operating systems and financial resources. If we fail to manage our growth or encounter unexpected difficulties during expansion it could have a material adverse effect on our financial condition and results of operations. The pursuit and integration of acquisitions, investments, joint ventures and strategic alliances will require substantial attention from our senior management, which will limit the amount of time available to devote to our existing operations. If we are 23

successful in consummating future acquisitions, we may have to incur substantial amounts of debt and contingent liabilities and an increase in amortization expenses related to goodwill and other intangible assets, all of which could have a material adverse effect on our financial condition and results of operations. We are currently evaluating potential acquisition and joint venture transactions that could require us to make substantial expenditures, possibly in the near term. See "Management's Discussion and Analysis of Financial Condition and Results of Operations--Liquidity and Capital Resources". Substantial Leverage; Restrictions Imposed by the Terms of Our Indebtedness We are a highly leveraged company. The following chart lays out certain important credit information and is presented as of September 30, 1998, (1) assuming we had completed the Offering and (2) assuming we had completed both the Offering and formed the Proposed Joint Venture. Pro Forma for the Pro Forma Offering for the and the Offering Proposed JV --------- ----------- (Dollars in thousands) Total indebtedness...... $425,324 $605,324 Redeemable preferred stock.................. 200,000 200,000 Stockholders' equity.... 745,117 942,117 Debt and redeemable preferred stock to equity ratio........... 0.84x 0.85x In addition, assuming we had completed the Offering and the Roll-Up on January 1, 1998, for the nine months ended September 30, 1998, our earnings would have been insufficient to cover fixed charges by $34.9 million. If we had also completed the Proposed Joint Venture on January 1, 1998, for the nine months ended September 30, 1998, our earnings would have been insufficient to cover fixed charges by $51.4 million. Given our substantial indebtedness, we could be affected in the following ways: . We could be more vulnerable to general adverse economic and industry conditions. . We may find it more difficult to obtain additional financing to fund future working capital, capital expenditures and other general corporate requirements. . We will be required to dedicate a substantial portion of our cash flow from operations to the payment of principal and interest on our debt, reducing the available cash flow to fund other projects. . We may have limited flexibility in planning for, or reacting to, changes in our business and in the industry. . We will have a competitive disadvantage relative to other less leveraged companies in our industry. Our ability to service our debt and to fund planned capital expenditures in connection with our business strategy will depend, to a degree, on factors beyond our control, including general economic, financial, competitive and regulatory environments. We cannot guarantee that we will be able to generate enough cash flow from operations or that we will be able to obtain enough capital to service our debt or fund our planned capital expenditures. Our current business plan contemplates substantial capital expenditures in connection with the expansion of our tower footprints. We believe that cash flow from operations and available cash from our credit facilities and the Offering will be sufficient to fund our planned capital expenditures for the foreseeable future. However, if the proposed joint venture is formed, these funds will not be sufficient to fund any significant acquisitions other than the proposed joint venture. We will therefore need additional equity or debt financing to fund any other strategic acquisitions of communications sites or transmission networks that we may pursue. We cannot guarantee, however, that such funding will be available on commercially reasonable terms or at all. See 24

"Management's Discussion and Analysis of Financial Condition and Results of Operations--Liquidity and Capital Resources". In addition, we may need to refinance some or all of our indebtedness on or before maturity. We cannot guarantee, however, that we will be able to refinance our indebtedness on commercially reasonable terms or at all. Currently we have debt instruments in place which restrict our ability to do certain things, including incurring more indebtedness, paying dividends, creating liens, selling assets and engaging in certain mergers and acquisitions. Certain of our subsidiaries, under the debt instruments, are also required to maintain specific financial ratios. Our ability to comply with the restrictions of these instruments and to satisfy our debt obligations will depend on our future operating performance. If we are unable to meet the debt restrictions, we will be in default under those instruments, which in certain cases will cause the maturity of those instruments to be accelerated. See "Description of Certain Indebtedness". The Proposed Joint Venture May Not Occur The Offering was not contingent on the consummation of the proposed joint venture, and we cannot guarantee that we will form the proposed joint venture. While we have signed a definitive agreement to establish the joint venture, there are many conditions that must be satisfied before the proposed joint venture will be formed, including: . the receipt of bank financing by the proposed joint venture; . the receipt of certain third party consents to the transfer of BAM's towers to the proposed joint venture; . absence of litigation; and . absence of any material adverse effect with respect to our business, assets, operations, conditions (financial or otherwise) or prospects. We cannot guarantee that these conditions will be satisfied or waived. See "Business--Proposed Joint Venture--Formation Agreement--Terms and Conditions." In addition, we cannot assure you that the proposed joint venture will be formed on the terms described in this document. For example, certain of the partnerships affiliated with BAM that are to contribute towers to the proposed joint venture (the "Transferring Partnerships") have not executed the Formation Agreement. If such entities do not agree to contribute their towers to the proposed joint venture, the number of towers to be held by the joint venture could decrease by as many as 350 (with a corresponding reduction in the amount of our investment). Further, BAM is permitted to sell up to 400 of the towers to be contributed to the proposed joint venture in connection with a sale by it of a cellular system prior to the formation of the proposed joint venture. If BAM were to make such a sale, the number of towers to be contributed to the proposed joint venture would be decreased by up to 400 (with a corresponding reduction in the amount of our investment). Furthermore, if the number of towers to be contributed to the proposed joint venture were to decrease by more than 200, the bank lender to the joint venture would not be required to provide financing to the joint venture and, accordingly, the joint venture might not be formed. If the proposed joint venture is not consummated or is consummated on significantly different terms than those described in this document, it could substantially affect our business strategy. Further, we cannot guarantee that we would be able to identify any other acquisition of comparable value to our business or that any other acquisition that we did pursue would be on substantially the same economic terms as the proposed joint venture. Moreover, the net proceeds from the Offering would not be used to established the proposed joint venture; we would therefore have substantial discretion in applying the proceeds of the Offering to other uses. See "--Broad Discretion in Application of Proceeds". 25

Ability to Pay Dividends on the Exchangeable Preferred Stock Our ability to pay any dividends is dependent on applicable provisions of state law, and our ability to pay cash dividends on the exchangeable preferred stock is subject to the terms of the Notes Indenture, which currently prohibit us from paying cash dividends on any preferred stock, including the exchangeable preferred stock. Our ability to pay dividends on the exchangeable preferred stock in the future will depend on our meeting certain financial criteria. See "Description of Certain Indebtedness". Moreover, under Delaware law we are permitted to pay dividends on our capital stock, including the exchangeable preferred stock, only out of surplus, or if there is no surplus, out of net profits for the year in which a dividend is declared or for the immediately preceding fiscal year. Surplus is defined as the excess of a company's total assets over the sum of its total liabilities plus the par value of its outstanding capital stock. In order to pay dividends in cash, we must have surplus or net profits equal to the full amount of the cash dividend at the time such dividend is declared. We cannot predict what the value of our assets or the amount of the liabilities will be in the future and, accordingly, we cannot guarantee that we will be able to pay cash dividends on the exchangeable preferred stock. Subordination of the Exchangeable Preferred Stock Our obligations with respect to the exchangeable preferred stock are subordinate and junior in right of payment to all our present and future indebtedness, including the Notes. In the event of a bankruptcy, liquidation or reorganization, our assets will be available to pay obligations on the exchangeable preferred stock only after we have paid all other indebtedness. Therefore, we may not have sufficient assets remaining to pay amounts due on any or all of the exchangeable preferred stock then outstanding. While any shares of exchangeable preferred stock are outstanding, we may not authorize, create or increase the amount of any class or series of stock that ranks senior to the exchangeable preferred stock with respect to the payment of dividends or amounts upon liquidation, dissolution or winding up without the consent of the holders of a majority of the outstanding shares of exchangeable preferred stock. However, without the consent of any holder of exchangeable preferred stock, we may create additional classes of stock, increase the authorized number of shares of preferred stock or issue a new series of stock that ranks pari passu with or junior to the exchangeable preferred stock with respect to the payment of dividends and amounts upon liquidation, dissolution or winding up. Subordination of the Exchange Debentures If the exchange debentures are issued, they will rank behind all of our existing indebtedness (other than trade payables) and all of our future borrowings (other than trade payables), except any future indebtedness that expressly provides that it ranks equal with, or subordinated in right of payment to, the exchange debentures. As a result, upon any distribution to our creditors in a bankruptcy, liquidation or reorganization or similar proceeding relating to us or our property, the holders of senior debt of our Company will be entitled to be paid in full in cash before any payment may be made with respect to the exchange debentures. In addition, all payments on the exchange debentures will be blocked in the event of a payment default on senior debt and may be blocked for up to 179 of 360 consecutive days in the event of certain non-payment defaults on senior debt. In the event of a bankruptcy, liquidation or reorganization or similar proceeding relating to our company, holders of the exchange debentures will participate with trade creditors and all other holders of subordinated indebtedness of the company in the assets remaining after we have paid all of the senior debt. However, because the indenture requires that amounts otherwise payable to holders of senior debt instead, holders of the exchange debentures may receive less, ratably, than holders of trade payables in any such proceeding. In any of these cases, we may not have sufficient funds to pay all of our creditors and holders of exchange debentures may receive less, ratably, than the holders of senior debt. 26

Assuming we had completed the Offering and applied the net proceeds as intended on September 30, 1998, as of that date we would have had $507.3 million of outstanding indebtedness and other liabilities (including approximately $343.3 million of indebtedness and other liabilities of our subsidiaries), all of which would have been senior in right of payment to the exchange debentures. Assuming we had consummated the proposed joint venture and the Offering and applied the net proceeds as intended on September 30, 1998, as of that date we would have had $687.3 million of indebtedness and other liabilities (including $523.3 million of indebtedness and other liabilities of our subsidiaries). See "Description of Securities--Description of the Senior Subordinated Exchange Debentures--Ranking". Broad Discretion in Application of Proceeds of the Offering While we plan on using a significant portion of the proceeds from the Offering for the Proposed Joint Venture, we cannot guarantee that it will be formed or that it will be formed on the terms described in this document. See "--The Proposed Joint Venture May Not Occur." If the proposed joint venture does not occur or if it occurs on terms different from those described, we would use the proceeds of the Offering that were intended for the proposed joint venture for working capital and general corporate purposes including as yet unidentified acquisitions, investments or joint ventures in the United States or abroad. In that situation, we would have broad discretion in allocating a significant portion of the net proceeds from the Offering without your action or approval. Accordingly, if the proposed joint venture is not formed as described in this document, you would not have the opportunity to evaluate the economic, financial and other relevant information that we would consider in determining the application of the net proceeds. See "Use of Proceeds". Even if we form the proposed joint venture and use the proceeds of the Offering as described in this document, we will have broad discretion in allocating the portion of the proceeds designated for general corporate purposes. Further, under the Notes Indenture and the Certificate of Designations, we are permitted to contribute the proceeds of the Offering to an unrestricted subsidiary. Holding Company Structure; Dependence on Dividends to Meet Cash Requirements or Pay Dividends We are a holding company with no business operations. Our only significant asset is the outstanding capital stock of our subsidiaries, through which we conduct all our business operations. We intend to contribute all of the net proceeds from the Offering to subsidiaries. We will rely on payments from our subsidiaries to be able to meet our obligations. We will not be able to pay out cash dividends on the exchangeable preferred stock, redeem the exchangeable preferred stock or pay interest and principal on the exchange debentures without receiving dividends from our subsidiaries. Furthermore, both CCI and CTI are restricted by their respective debt instruments on paying dividends or making distributions to the Company. In addition, our subsidiaries are permitted under the terms of their existing debt instruments to incur certain additional indebtedness that also may restrict or prohibit distributions, dividends or loans to the parent company. See "--Substantial Leverage; Restrictions Imposed by the Terms of Our Indebtedness" and "Description of Certain Indebtedness". Risks Related to Agreements with TdF We have entered into certain agreements with TdF that give TdF significant protective rights with respect to the governance of CCIC and CTI, the ownership of CTI and the disposition of shares in CCIC and CTI. CTI's operations currently account for a substantial majority of our revenues. Governance Rights We have granted TdF the ability to govern some of our activities, including the ability to: . prohibit us from entering into certain material transactions; . elect up to two members of our Board of Directors; and . elect at least one director to the executive, nominating and corporate governance committees of our Board of Directors. 27

In addition, TdF has significant governance rights over CTI. Although TdF has only a 20% equity interest in CTI, these governance rights give TdF generally the same rights that a 50% partner to a joint venture would have. While TdF's governance rights are limited in certain ways and are automatically forfeited under certain conditions, they nonetheless give TdF significant control over our activities. TdF's exercise of these rights could be contrary to your interests and could prevent us from conducting certain activities that our Board of Directors consider to be in our best interests and the best interests of our shareholders. See "Certain Transactions-- Governance Agreement". CTSH Option Under certain circumstances, TdF will also have the right to acquire all of our shares in CTSH or to require us to purchase all of TdF's shares in CTSH (at fair market value in either case). This right will be triggered under the following circumstances: . the sale of all or substantially all of our assets; . a merger, consolidation or similar transaction that would result in any person owning more than 50% of our voting power or equity securities; . an unsolicited acquisition by any person of more than 25% (or 30% if we notify TdF in writing) of our voting power or equity securities; or . other circumstances arising from an acquisition by any person that would give rise to a right of the BBC to terminate our analog transmission contract with the BBC or our digital transmission contract with the BBC. Further, immediately before any of these events occurs, TdF will have the right to require us to purchase 50% of their Class A Common Stock in cash at the same price we would have to pay once the event occurs. If we were required to sell our shares in CTSH to TdF, we would no longer own the CTI business. On the other hand, if we were required to purchase all of TdF's shares in CTSH and/or purchase 50% of their Class A Common Stock, we cannot guarantee that we would have the necessary funds to do so or that we would be permitted to do so under our debt instruments. If we did not have sufficient funds, we would have to obtain additional financing. We cannot guarantee, however, that such financing would be available on commercially reasonable terms or at all. If such financing were not available, we might be forced to sell certain other assets at unfavorable prices in order to generate the cash needed to buy the shares from TdF. In addition, our obligation to purchase TdF's shares could result in an event of default under our debt instruments. Liquidity Rights Under certain other circumstances, TdF will have the right to require us to purchase all of their shares in CTSH, at fair market value. We may elect to pay either (1) in cash or (2) with our common stock at a discount of 15% to its market value. If we were to issue shares of our common stock to effect the purchase, our ability to raise additional capital through the sale of our equity securities could be impaired. Risks Associated with Construction and Acquisition of Towers Our growth strategy depends on our ability to construct, acquire and operate towers in conjunction with the expansion of wireless communications carriers. As of September 30, 1998, we had 66 towers under construction and had plans to commence construction on approximately 600 additional towers during fiscal 1999 (not including any towers to be constructed by the proposed joint venture). Our ability to construct new towers can be affected by a number of factors beyond our control, including: . zoning and local permitting requirements and national regulatory approvals; 28

. availability of construction equipment and skilled construction personnel; and . bad weather conditions. In addition, as the concern over tower proliferation has grown in recent years, certain communities have placed restrictions on new tower construction or have delayed granting permits required for construction. You should consider that: . the barriers to new construction may prevent us from building towers where we want; . we may not be able to complete the number of towers planned for construction in accordance with the requirements of our customers; and . we cannot guarantee that there will be a significant need for the construction of new towers once the wireless communications carriers complete the build-out of their tower network infrastructure. Competition for the acquisition of towers is keen, and we expect it to continue to grow. We not only compete against other independent tower owners and operators, but also against certain wireless communications carriers, broadcasters and site developer. As competition increases for tower acquisitions, we may be faced with fewer acquisition opportunities, as well as higher acquisition prices. While we regularly explore acquisition opportunities, we cannot guarantee that we will be able to identify suitable towers to acquire in the future. In addition, we may need to seek additional debt or equity financing in order to fund such acquisitions. We cannot, however, guarantee that such financing will be available or that the proposed financings will be permitted under our debt instruments. Moreover, we cannot guarantee that we will be able to identify, finance and complete future construction and acquisitions on acceptable terms or that we will be able to manage profitably and market under-utilized capacity on additional towers. The extent to which we are unable to construct or acquire additional towers, or manage profitably tower expansion, may have a material adverse effect on our financial condition and results of operations. We believe that the time frame for the current wireless build-out cycle may be limited to the next few years, as many PCS and PCN networks have already been built out in large markets. If we do not move quickly and aggressively to obtain growth capital and capture this infrastructure opportunity, our financial condition and results of operations could be materially adversely affected. Dependence on Demand for Wireless Communications; Risk Associated with New Technologies Demand for our site rentals depends on demand for communication sites from wireless communication carriers, which, in turn, depends on the demand for wireless services. Most types of wireless services currently require ground- based network facilities, including communication sites for transmission and reception. The demand for our sites depends on certain factors which we cannot control, including: . the level of demand for wireless services generally; . the financial condition and access to capital of wireless carriers; . the strategy of carriers with respect to owning or leasing communication sites; . changes in telecommunications regulations; and . general economic conditions. The wireless communications industry has experienced significant growth in recent years. A slowdown in the growth of, or reduction in, demand in a particular wireless segment could adversely affect the demand for communication sites. For example, we anticipate that a significant amount of our revenues over the next several years will be generated from carriers in the PCS and PCN market and, as such, we will be subject to downturns in PCS and PCN demand. Moreover, wireless communications carriers often operate with substantial leverage, and financial problems for our customers could result in accounts receivable going uncollected, in the loss of a customer and the associated lease revenue or in a reduced ability of these customers to finance expansion activities. 29

Finally, advances in technology, such as the development of new satellite systems, could reduce the need for land-based transmission and reception networks. The occurrence of any of these factors could have a material adverse effect on our financial condition and results of operations. Variability in Demand for Network Services Demand for our network services fluctuates from period to period and within periods. These fluctuations are caused by a number of factors, including: . the timing of customers' capital expenditures; . annual budgetary considerations of customers; . the rate and volume of wireless communications carriers' tower build- outs; . timing of existing customer contracts; and . general economic conditions. While demand for our network services fluctuates, we must incur certain costs, such as maintaining a staff of network services employees in anticipation of future contracts, even when there may be no current business. Consequently, the operating results of our network services businesses for any particular period may vary significantly, and should not be considered as necessarily being indicative of longer-term results. For example, we experienced a decline, as compared to the two previous quarters, in demand for our network services business in the fourth quarter of 1997 and the first quarter of 1998. Furthermore, as wireless communications carriers complete their build-outs, the need for the construction of new towers and the demand for certain network services could decrease significantly and could result in fluctuations and, possibly, significant declines in our operating performance. Competition We face competition for site rental customers from various sources, including: . other large independent tower owners; . wireless communication carriers that own and operate their own tower footprints and lease antenna space to other carriers; . site development companies which acquire antenna space on existing towers for wireless communications carriers and manage new tower construction; and . traditional local independent tower operators. Wireless communications carriers that own and operate their own tower footprints generally are substantially larger and have greater financial resources than we have. We believe that tower location and capacity, price, quality of service and density within a geographic market historically have been and will continue to be the most significant competitive factors affecting the site rental business. We compete for acquisition and new tower construction opportunities with wireless communications carriers, broadcasters, site developers and other independent tower operators. We believe that competition for tower acquisitions will increase and that additional competitors will enter the tower market. These additional competitors may have greater financial resources than we have. See "--Risks Associated with Construction and Acquisition of Towers". NTL, which owns the privatized engineering division of the Independent Broadcasting Authority, is our principal competitor in the terrestrial broadcast transmission market in the United Kingdom. We could encounter significant competition from NTL for our transmission business with the BBC or ONdigital following the expiration of our current contracts with these broadcasters. See "--Reliance on Significant Agreements". 30

Reliance on Significant Agreements Assuming we had completed the Roll-Up as of January 1, 1998, for the nine month period ended September 30, 1998, none of our customers would have accounted for more than ten percent of our revenues, except the BBC, which would have accounted for 45.4% of our revenues. If the proposed joint venture had been completed as of January 1, 1998, BAM and the BBC would have accounted for 12.7% and 37.6% of our revenues, respectively, for that same period. Our broadcast transmission business is substantially dependent on contracts with the BBC. See "Business--U.K. Operations--Significant Contracts". The prices that we charge the BBC for analog television and radio transmission services are subject to regulation by the U.K. Office of Telecommunications ("OFTEL"). See "--Regulatory Compliance and Approval". The initial term of our analog transmission contract with the BBC will expire on March 31, 2007, and our digital transmission contract with the BBC expires on October 31, 2010. In addition, our digital transmission contract with the BBC may be terminated by the BBC after five years if the BBC's Board of Governors does not believe that digital television in the United Kingdom has enough viewers, subject to payment to CTI of predetermined cash compensation payments if this occurs. We cannot guarantee that the BBC will renew these contracts or that they will not attempt to negotiate terms that are not as favorable as those in place now. If we were to lose the BBC contracts, our business, results of operations and financial condition could be materially adversely affected. See "Business-- U.S. Operations--Significant Contracts--Nextel Agreement". Our agreement with Nextel is also significant to our business and results of operations. Under certain circumstances, Nextel could terminate the agreement. Since this agreement represents a significant part of our business strategy, and we expect site-sharing with Nextel to represent an even larger portion of our business in the future, if Nextel were to terminate the agreement, our ability to achieve our business strategy could be materially adversely affected. In order to optimize service coverage in the United Kingdom and enable viewers to receive all analog UHF television services using one receiving antenna, CTI and NTL have agreed to share all UHF television sites. See "Business--U.K. Operations--Significant Contracts". We are currently in negotiations with NTL to amend the agreement to reflect the build-out of digital transmission sites and equipment, new rates for site sharing fees for new digital facilities and revised operating and maintenance procedures for the new equipment. This agreement may be terminated with five years' notice by either CTI or NTL, and is set to expire on December 31, 2005. Although we do not believe that the agreement will be terminated, we cannot guarantee that it will not be, which could have a material adverse effect on our business, results of operations and financial condition. Regulatory Compliance and Approval We are subject to a variety of foreign, federal, state and local regulation. In the United States, both the Federal Communications Commission (the "FCC") and Federal Aviation Administration (the "FAA") regulate towers and other sites used for wireless communications transmitters and receivers. Such regulations control siting and marking of towers and may, depending on the characteristics of the tower, require registration of tower facilities. Wireless communications devices operating on towers are separately regulated and independently licensed based upon the regulation of the particular frequency used. Most proposals to construct new antenna structures or to modify existing antenna structures are reviewed by both the FCC and the FAA to ensure that a structure will not present a hazard to aviation. Owners of towers may have an obligation to paint them or install lighting to conform to FCC standards and to maintain such painting or lighting. Tower owners may also bear the responsibility for notifying the FAA of any tower lighting failures. We generally indemnify our customers against any failure to comply with applicable standards. Failure to comply with applicable requirements may lead to civil penalties or require us to assume costly indemnification obligations. Local regulations include city or other local ordinances, zoning restrictions and restrictive covenants imposed by community developers. These regulations vary greatly, but typically require tower owners to obtain approval from local officials or community standards organizations prior to tower construction. Local regulations can delay or prevent new tower 31

construction or site upgrade projects, thereby limiting our ability to respond to customers' demands. In addition, such regulations increase the costs associated with new tower construction. We cannot guarantee that existing regulatory policies will not adversely affect the timing or cost of new tower construction or that additional regulations will not be adopted which increase such delays or result in additional costs. These factors could have a material adverse effect on our financial condition and results of operations. In the United Kingdom, both OFTEL and the Radiocommunications Agency regulate and monitor telecommunications and frequency licensing for sites used for wireless communications transmitters and receivers. Site rental fees for broadcasting (but not telecommunications) are also subject to price regulation by OFTEL. In order to construct or materially alter towers, we must receive regulatory approvals from the Civil Aviation Authority, which ensures that new antenna structures do not present a hazard to aviation, and from local government planning authorities. In addition, we sometimes must receive international frequency clearance. Our ability to respond to customers' demands may be delayed or even prevented by the need to seek these approvals. We cannot guarantee, therefore, that existing regulatory policies will not adversely affect the timing or cost of new tower construction or that additional regulations will not be adopted which increase such delays or result in additional costs. These factors could have a material adverse effect on our financial condition and results of operations. Since we signed the analog transmission contract with the BBC, the BBC has increased its service requirements to include 24-hour broadcasting on our terrestrial transmission network for the BBC's two national television services and a requirement for CTI to add a number of filler stations to its network to extend existing BBC services. The BBC has agreed to increases of approximately (Pounds)800,000 ($1,359,600) per year in the charges payable by the BBC to CTI for these service enhancements. The additional charges may necessitate an amendment to CTI's Transmission Telecommunications License. OFTEL, the relevant regulatory authority in the United Kingdom, has confirmed in initial discussions with CTI that it is not OFTEL's intention to prevent the provision of such additional services to the BBC at an additional charge. CTI is discussing with OFTEL the most appropriate way to rectify this situation in order to allow the additional services to be provided to the BBC in return for the additional agreed payments. While we expect the license to be amended, there can be no assurance as to the final resolution of these issues with OFTEL. Our customers may also become subject to new regulations or regulatory policies which adversely affect the demand for communication sites. In addition, as we pursue international opportunities, we will be subject to regulation in foreign jurisdictions. We are also subject to laws and regulations relating to worker health and safety. If we fail to comply with such laws and regulations, it could have a material adverse effect on our business, results of operations or financial condition. See "Business--Environmental Matters". Environmental Matters Our operations are subject to foreign, federal, state and local laws and regulations regarding the management, use, storage, disposal, emission, release and remediation of, and exposure to, hazardous and nonhazardous substances, materials or wastes. Under certain environmental laws, we could be held liable for the remediation of hazardous substance contamination at current or former facilities or at third-party waste disposal sites, and also could be subject to personal injury or property damage claims related to such contamination. Although we believe that we are in substantial compliance with all applicable environmental laws, we cannot guarantee that costs of compliance with existing or future environmental laws will not have a material adverse effect on our financial condition and results of operations. See "Business--Environmental Matters". Perceived Health Risks Associated with Radio Frequency Emissions Our towers are subject to government requirements and other guidelines relating to radio frequency emissions. The potential connection between radio frequency emissions and certain negative health effects, 32

including some forms of cancer, has been the subject of substantial study by the scientific community in recent years. To date, the results of these studies have been inconclusive. Although we have not been subject to any claims relating to radio frequency emissions, we cannot guarantee that we will not be subject to such claims in the future. Risks Associated with International Operations We conduct business in countries outside the United States, which exposes us to fluctuations in foreign currency exchange rates. For the first nine months of 1998, assuming we had completed the Roll-Up on January 1, 1998, approximately 75% of our consolidated revenues would have originated outside the United States, all of which were denominated in currencies other than U.S. dollars (principally pounds sterling). We have not historically engaged in significant hedging activities with respect to our non-U.S. dollar operations. Our international operations are subject to other risks, such as the imposition of government controls, inflation, tariff or taxes and other trade barriers, difficulties in staffing and managing international operations, price, wage and exchange controls, and political, social and economic instability. We cannot guarantee that these and other factors will not have a material adverse effect on our financial condition or results of operations. Dependence on Principal Executive Officers Our existing operations and continued future development are dependent to a significant extent upon the performance and active participation of certain key individuals, including senior management. We cannot guarantee that we will be successful in retaining the services of these, or other key personnel. None of our employees have signed noncompetition agreements. If we were to lose any of these individuals, our financial condition and results of operations could be materially adversely affected. Year 2000 Compliance We are in the process of conducting a comprehensive review of our computer systems to identify which of our systems will need to be modified, upgraded or converted to recognize and process dates after December 31, 1999 (the "Y2K problem"). The failure to correct a material Y2K problem could result in an interruption in, or failure of, certain normal business activities or operations. Such failures could materially and adversely affect our results of operations, liquidity and financial condition. Due to the general uncertainty inherent in the Y2K problem, resulting in part from the uncertainty of whether our suppliers and customers are addressing the Y2K problem, we are unable to determine at this time whether failures brought on by the Y2K problem will have a material adverse effect on our results of operations, liquidity or financial condition. We believe that, with the implementation of new business systems, the possibility of significant interruptions of normal operations should be reduced; however, we cannot guarantee that our business, financial condition and results of operations will not be materially adversely affected if we or our customers or contractors fail to resolve the Y2K problem in a timely manner. Repurchase of the Exchangeable Preferred Stock or the Exchange Debentures Upon a Change of Control Under the Certificate of Designation (in the case of the exchangeable preferred stock) and the Exchange Indenture (in the case of the exchange debentures), in the event of certain changes of control of CCIC: . we are required to offer to purchase all outstanding shares of exchangeable preferred stock, in whole or in part, at a purchase price equal to 101% of its aggregate liquidation preference, plus accumulated and unpaid dividends; and . each holder of exchange debentures may require us to purchase their exchange debentures, in whole or in part, at a purchase price equal to 101% of their aggregate principal amount, plus any accrued and unpaid interest. 33

In the case of the senior exchangeable preferred stock, our offer to repurchase upon a change of control must comply with certain provisions of our existing senior notes indenture. If we are unable to comply with those provisions and fail to repurchase senior exchangeable preferred stock, then holders of the senior exchangeable preferred stock would be entitled to certain voting rights. In addition, if a change of control were to occur, we may not have the financial resources to repurchase all of the exchangeable preferred stock and/or exchange debentures and repay any other indebtedness that would become payable upon the occurrence of the change of control. This feature of the exchangeable preferred stock and exchange debentures may in certain circumstances discourage or make more difficult a sale or takeover of the Company. Lack of Public Market for the Securities The shares of new preferred stock will be new securities for which there currently is no established trading market. We do not intend to apply for listing of the new preferred stock on a national securities exchange or automatic quotation system. Although the initial purchasers of the old preferred stock have informed us that they currently intend to make a market in the new preferred stock, the initial purchasers are not obligated to do so, and any such market making may be discontinued at any time without notice. The liquidity of any market for the shares of new preferred stock will depend upon the number of holders of the new preferred stock, the interest of securities dealers in making a market in the new preferred stock and other factors. Accordingly, there can be no assurance as to the development or liquidity of any market for the shares of new preferred stock. If an active trading market for the shares of new preferred stock does not develop, the market price and liquidity of the shares of new preferred stock may be adversely affected. If the shares of new preferred stock are traded, they may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar securities, our financial performance and certain other factors. The liquidity of, and trading markets for, the shares of new preferred stock also may be adversely affected by general declines in the market for payment-in-kind preferred stock. Such declines may adversely affect the liquidity of, and trading markets for, the shares of new preferred stock, independent of our financial performance or prospects. Historically, the market for payment-in-kind preferred stock has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the new preferred stock. There can be no assurance that the market, if any, for the shares of new preferred stock will not be subject to similar disruptions. Any such disruptions may have an adverse effect on the holders of the new preferred stock. USE OF PROCEEDS We will not receive any proceeds from the Exchange Offer. DIVIDEND POLICY The Company has never declared or paid any cash dividends on its capital stock and does not anticipate paying cash dividends on its capital stock in the foreseeable future. It is the current policy of the Company's Board of Directors to retain earnings to finance the expansion of the Company's operations. Future declaration and payment of dividends, if any, will be determined in light of the then-current conditions, including the Company's earnings, operations, capital requirements, financial condition and other factors deemed relevant by the Board of Directors. In addition, the Company's ability to pay dividends is limited by the terms of the Notes Indenture and the terms of the Certificate of Designations. See "Description of Securities-- Description of the Exchangeable Preferred Stock", "Description of Certain Indebtedness" and "Description of Capital Stock". 34

CAPITALIZATION The following table sets forth as of September 30, 1998 (i) the historical capitalization of the Company, (ii) the pro forma capitalization of the Company after giving effect to the Offering and (iii) the pro forma capitalization of the Company after giving effect to the Offering and the Proposed JV. The information set forth below should be read in conjunction with "Unaudited Pro Forma Condensed Consolidated Financial Statements", "Management's Discussion and Analysis of Financial Condition and Results of Operations" and the consolidated financial statements and the notes thereto included elsewhere in this document.

See "Description of Certain Indebtedness". On a pro forma basis to reflect the repayment of borrowings under the Senior Credit Facility from a portion of the net proceeds of the Offering, CCI would have approximately $73.9 million of unused borrowing availability under the Senior Credit Facility. (b) On a pro forma basis for the Offering and the Proposed JV, the Restricted Group (as defined) would have cash and cash equivalents, total long-term debt, redeemable preferred stock, total stockholders' equity and total capitalization of $49.9 million, $163.8 million, $200.0 million, $942.1 million and $1,305.9 million, respectively. See "Unaudited Pro Forma Condensed Consolidated Financial Statements--Notes to Unaudited Pro Forma Condensed Consolidated Balance Sheet". (c) The Company's issuance of approximately 15.6 million shares of its common stock in connection with the formation of the proposed joint venture will give TdF the right to purchase up to approximately 4.46 million shares of the Company's common stock at approximately $12.65 per share pursuant to TdF's antidilutive right under the Governance Agreement. See "Certain Relationships and Related Transactions--Governance Agreement". 35

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS The following unaudited pro forma condensed consolidated financial statements (the "Pro Forma Financial Statements") are based on the historical financial statements of CCIC and the historical financial statements of the entities acquired by CCIC (including TEA and Crown) during the periods presented, adjusted to give effect to the following transactions (collectively, the "Transactions"): (i) the CTI Investment, (ii) the TEA Acquisition, (iii) the acquisition of TeleStructures (the "TeleStructures Acquisition"), (iv) the Crown Merger (together with the acquisitions described in clauses (i), (ii) and (iii), the "Historical Acquisitions"), (v) the 1997 Refinancing, (vi) the Roll-Up, (vii) the IPO, (viii) the Senior Preferred Conversion, (ix) the Offering and (x) the Proposed JV. The Unaudited Pro Forma Condensed Consolidated Statement of Operations for the year ended December 31, 1997 gives effect to the Transactions as if they had occurred as of January 1, 1997, and the Unaudited Pro Forma Condensed Consolidated Statement of Operations for the nine months ended September 30, 1998 gives effect to the Roll-Up, the IPO, the Senior Preferred Conversion, the Offering and the Proposed JV as if they had occurred as of January 1, 1998. The Unaudited Pro Forma Condensed Consolidated Balance Sheet gives effect to the Offering and the Proposed JV as if they had occurred as of September 30, 1998. The pro forma adjustments are described in the accompanying notes and are based upon available information and certain assumptions that management believes are reasonable. Included in the notes accompanying the Pro Forma Financial Statements are tables summarizing the unaudited pro forma results of operations and balance sheet for CCIC and its Restricted Subsidiaries (as defined in the Indenture governing the Notes, the "Indenture"); such group of companies is hereinafter referred to as the "Restricted Group". The Restricted Group excludes CTI and the Proposed JV, both of which are designated as Unrestricted Subsidiaries (as defined in the Indenture). The Pro Forma Financial Statements do not purport to represent what CCIC's results of operations or financial condition would actually have been had the Transactions in fact occurred on such dates or to project CCIC's results of operations or financial condition for any future date or period. The Pro Forma Financial Statements should be read in conjunction with the consolidated financial statements and the notes thereto included elsewhere in this document and "Management's Discussion and Analysis of Financial Condition and Results of Operations". The Historical Acquisitions, the Roll-Up and the Proposed JV are accounted for under the purchase method of accounting. The total purchase price for each Historical Acquisition, the Roll-Up and the Proposed JV have been allocated to the identifiable tangible and intangible assets and liabilities of the applicable acquired business based upon CCIC's preliminary estimate of their fair values with the remainder allocated to goodwill and other intangible assets. The allocations of the purchase prices are subject to revision when additional information concerning asset and liability valuations is obtained; however, the Company does not expect that any such revisions will have a material effect on its consolidated financial position or results of operations. The Company has recorded the purchase price for the Roll-Up based on (i) the number of shares of CCIC's Common Stock and Class A Common Stock exchanged for shares of CTI's capital stock and (ii) the price per share received by CCIC from the IPO. 36

These expenses consist primarily of allocated compensation, benefits and overhead costs that are not directly related to the administration or management of existing towers. For the 47

year ended December 31, 1997, such expenses include (i) nonrecurring cash bonuses of $0.9 million paid to certain executive officers in connection with the CTI Investment and (ii) a nonrecurring cash charge of $1.3 million related to the purchase by CCIC of shares of Common Stock from CCIC's former chief executive officer in connection with the CTI Investment. See "Certain Relationships and Related Transactions". (b) Includes a $1.2 million fee received in March 1997 as compensation for leading the investment consortium which provided the equity financing for CTI in connection with the CTI Investment. (c) Represents the aggregate number of sites of CCIC as of the end of each period. (d) As of September 30, 1998, CCIC had contracts with 1,367 buildings in the United States to manage on behalf of such buildings the leasing of space for antenna on the rooftops of such buildings. A revenue producing rooftop represents a rooftop where CCIC has arranged a lease of space on such rooftop and, as such, is receiving payments in respect of its management contract. CCIC generally does not receive any payment for rooftops under management unless CCIC actually leases space on such rooftops to third parties. As of September 30, 1998, CCIC had 1,286 rooftop sites under management throughout the United States that were not revenue producing but were available for leasing to customers and, in the United Kingdom, the Company had 54 revenue producing rooftop sites that were occupied by the Company's transmitters but were not available for leasing to customers. (e) EBITDA is defined as operating income (loss) plus depreciation and amortization and non-cash compensation charges. Adjusted EBITDA is defined as the sum of (i) annualized site rental and broadcast transmission EBITDA before corporate development for the most recent calendar quarter and (ii) EBITDA, less site rental and broadcast transmission EBITDA before corporate development, for the most recent four calendar quarters. EBITDA and Adjusted EBITDA are presented as additional information because management believes them to be useful indicators of CCIC's ability to meet debt service and capital expenditure requirements. They are not, however, intended as alternative measures of operating results or cash flow from operations (as determined in accordance with generally accepted accounting principles). Furthermore, CCIC's measure of EBITDA may not be comparable to similarly titled measures of other companies. (f) For purposes of computing the ratio of earnings to fixed charges, earnings represent income (loss) before income taxes, fixed charges and equity in earnings (losses) of unconsolidated affiliate. Fixed charges consist of interest expense, the interest component of operating leases and amortization of deferred financing costs. For the years ended December 31, 1995, 1996 and 1997 and the nine months ended September 30, 1997 and 1998, earnings were insufficient to cover fixed charges by $21,000, $0.9 million, $10.8 million, $5,000 and $32.0 million, respectively. (g) Net debt represents total debt less cash and cash equivalents. (h) Represents (i) the Senior Convertible Preferred Stock privately placed by CCIC in August 1997 and October 1997, all of which has been converted into shares of Common Stock, and (ii) the Series A Convertible Preferred Stock, the Series B Convertible Preferred Stock and the Series C Convertible Preferred Stock privately placed by CCIC in April 1995, July 1996 and February 1997, respectively, all of which has been converted into shares of Common Stock in connection with the IPO. 48

SELECTED FINANCIAL AND OTHER DATA OF CTI The selected historical financial data for CTI, which was 34.3% owned by CCIC prior to the Roll-Up, presents (i) selected historical financial data of the BBC Home Service Transmission Business prior to its acquisition by CTI (the "Predecessor") for the year ended March 31, 1996 and the eleven and two months ended February 27, 1997, (ii) selected historical consolidated financial data of CTI after such acquisition for the one month ended March 31, 1997 and for the nine months ended December 31, 1997, and (iii) selected historical consolidated financial data of CTI for the eight months ended August 31, 1998. The selected historical financial data for the year ended March 31, 1996 and the eleven months ended February 27, 1997 have been derived from the financial statements of the Predecessor, which have been audited by KPMG, Chartered Accountants. The selected financial data for the one month ended March 31, 1997 and the nine months ended December 31, 1997 have been derived from the consolidated financial statements of CTI, which have been audited by KPMG, Chartered Accountants. The selected historical financial data for the two months ended February 27, 1997 have been derived from the unaudited financial statements of the Predecessor, and the selected historical financial data for the eight months ended August 31, 1998 have been derived from the unaudited consolidated financial statements of CTI, which include all adjustments that CTI considers necessary for a fair presentation of the financial position and results of operations for that period. The results of operations for the one month ended March 31, 1997, the nine months ended December 31, 1997 and the eight months ended August 31, 1998 are not necessarily indicative of the results of operations of CTI that may be expected for the entire year. CCIC acquired a majority ownership interest in CTI upon consummation of the Roll-Up in August 1998 and, as a result, historical financial data of CTI for the nine months ended September 30, 1998 is not presented. This information reflects financial data for CTI as a whole, is not limited to that portion of the financial data attributable to CCIC's percentage ownership of CTI prior to the Roll-Up and is not indicative of any distributions or dividends that CCIC might receive in the future. CTI is subject to significant restrictions on its ability to make dividends and distributions to CCIC. See "Risk Factors--Holding Company Structure; Dependence on Dividends to Meet Cash Requirements or Pay Dividends".

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion sets forth separately the historical consolidated results of operations of CCIC and CTI and is intended to assist in understanding (i) CCIC's consolidated financial condition as of September 30, 1998 and its consolidated results of operations for the nine-month periods ended September 30, 1997 and 1998 and for each year in the three-year period ended December 31, 1997 and (ii) CTI's consolidated results of operations for each twelve-month period in the two-year period ended March 31, 1998. The statements in this discussion regarding the industry outlook, the Company's expectations regarding the future performance of its businesses and the other nonhistorical statements in this discussion are forward-looking statements. These forward-looking statements are subject to numerous risks and uncertainties, including but not limited to the uncertainties relating to decisions on capital expenditures to be made in the future by wireless communications carriers and broadcasters and the risks and uncertainties described in "Risk Factors". This discussion should be read in conjunction with "Unaudited Pro Forma Condensed Consolidated Financial Statements", "Selected Financial and Other Data of CCIC", "Selected Financial and Other Data of Crown", "Selected Financial and Other Data of CTI" and the consolidated financial statements and the notes thereto included elsewhere in this document. Results of operations of the acquired businesses that are wholly owned are included in the Company's consolidated financial statements for the periods subsequent to the respective dates of acquisition. As such, the Company's results of operations for the nine months ended September 30, 1997 are not comparable to the results of operations for the nine months ended September 30, 1998, and the results for the year ended December 31, 1996 are not comparable to the year ended December 31, 1997. Overview The continued growth of the Company's business depends substantially on the condition of the wireless communications and broadcast industries. The Company believes that the demand for communications sites will continue to grow and expects that, due to increased competition, wireless communications carriers will continue to seek operating and capital efficiencies by (i) outsourcing certain network services and the build-out and operation of new and existing infrastructure and (ii) co-locating antennas and transmission equipment on multiple tenant towers. In addition, wireless communications carriers are beginning to seek to sell their wireless communications infrastructure to, or establish joint ventures with, experienced infrastructure providers, such as the Company, that have the ability to manage networks. Further, the Company believes that wireless communications carriers and broadcasters ultimately will seek to outsource the operation of their towers and transmission networks, including the transmission of their signals. Management believes that the Company's ability to manage towers and transmission networks and its proven track record of providing end-to-end services to the wireless communications and broadcasting industries position it to capture such business. The willingness of wireless communications carriers to utilize the Company's infrastructure and related services is affected by numerous factors, including consumer demand for wireless services, interest rates, cost of capital, availability of capital to wireless carriers, tax policies, willingness to co- locate equipment, local restrictions on the proliferation of towers, cost of building towers and technological changes affecting the number of communications sites needed to provide wireless communications services to a given geographic area. The Company's revenues that are derived from the provision of transmission services to the broadcasting industry will be affected by the timing of the commencement of digital terrestrial television broadcasts in both the United Kingdom and the United States, as well as in other countries around the world, consumer demand for digital terrestrial broadcasting, interest rates, cost of capital, zoning restrictions on tall towers and the cost of building towers. As an important part of its business strategy, the Company will seek (i) to take advantage of the operating leverage of its site rental business by increasing the antenna space leased on its owned or managed communications sites, (ii) to leverage its in-house technical and operational expertise, (iii) to expand its tower footprints by partnering with wireless communications carriers to assume ownership of their existing towers and by pursuing build-to-suit opportunities and (iv) to acquire existing transmission networks globally as opportunities arise. 52

Results of Operations The Company's primary sources of revenues are from (i) the rental of antenna space on towers and rooftops sites, (ii) the provision of network services and (iii) the provision of analog and digital broadcast transmission services. CCIC CCIC's primary sources of revenues are from (i) the rental of antenna space on towers and rooftop sites and (ii) the provision of network services, which includes network design and site selection, site acquisition, site development and construction and antenna installation. Site rental revenues are received primarily from wireless communications companies, including cellular, PCS, paging, specialized mobile radio/enhanced specialized mobile radio ("SMR/ESMR") and microwave operators. Site rental revenues are generally recognized on a monthly basis under lease agreements, which typically have original terms of five years (with three or four optional renewal periods of five years each). Average revenues for CCIC's managed rooftop sites are less than for the owned and managed towers because a substantial portion of the revenues from the tenants at rooftop sites is remitted to the building owner or manager. Network services revenues consist of revenues from (i) network design and site selection, (ii) site acquisition, (iii) site development and construction, (iv) antenna installation and (v) other services. Network services revenues are received primarily from wireless communications companies. Network services revenues are recognized under service contracts which provide for billings on either a fixed price basis or a time and materials basis. Demand for CCIC's network services fluctuates from period to period and within periods. See "Risk Factors--Variability in Demand for Network Services". Consequently, the operating results of CCIC's network services businesses for any particular period may vary significantly, and should not be considered as indicative of longer-term results. CCIC also derives revenues from the ownership and operation of microwave radio and SMR networks in Puerto Rico where CCIC owns radio wave spectrum in the 2,000 MHz and 6,000 MHz range (for microwave radio) and the 800 MHz range (for SMR). These revenues are generally recognized under monthly management or service agreements. Costs of operations for site rental primarily consist of land leases, repairs and maintenance, utilities, insurance, property taxes and monitoring costs as well as, in the case of managed sites, rental payments. For any given tower, such costs are relatively fixed over a monthly or an annual time period. As such, operating costs for owned towers do not generally increase significantly as additional customers are added. However, rental expenses at certain managed towers increase as additional customer antennas are added, resulting in higher incremental revenues but lower incremental margins than on owned towers. Costs of operations for network services consist primarily of employee compensation and related benefits costs, subcontractor services, consulting fees, and other on-site construction and materials costs. CCIC incurs these network services costs (i) to support its internal operations, including construction and maintenance of its owned towers, and (ii) to maintain the employees necessary to provide end-to-end services to third parties regardless of the level of such business at any time. The Company believes that its experienced staff enables it to provide the type of end-to- end services that enhance its ability to acquire access to the infrastructure of wireless communications carriers and to attract significant build-to-suit contracts. General and administrative expenses consist primarily of employee compensation and related benefits costs, advertising, professional and consulting fees, office rent and related expenses and travel costs. Corporate development expenses represent costs incurred in connection with acquisitions and development of new business initiatives. These expenses consist primarily of allocated compensation, benefits and overhead costs that are not directly related to the administration or management of existing towers. Depreciation and amortization charges relate to CCIC's property and equipment (primarily towers, construction equipment and vehicles), goodwill and other intangible assets recorded in connection with business acquisitions. Depreciation of towers and amortization of goodwill are computed with a useful life of 20 years. 53

Amortization of other intangible assets (principally the value of existing site rental contracts at Crown) is computed with a useful life of 10 years. Depreciation of construction equipment and vehicles are generally computed with useful lives of 10 years and 5 years, respectively. In May 1997, the Company consummated the TEA Acquisition and the TeleStructures Acquisition. In August 1997, the Company consummated the Crown Merger. In August 1998, the Company consummated a share exchange with the shareholders of CTI, pursuant to which the Company's ownership of CTI increased from approximately 34.3% to 80%. Results of operations of these acquired businesses are included in the Company's consolidated financial statements for the periods subsequent to the respective dates of acquisition. As such, the Company's results of operations for the three and nine months ended September 30, 1997 are not comparable to the results of operations for the three and nine months ended September 30, 1998. See "--CTI" for a description of the revenues and operating expenses that are included in CCIC's consolidated results of operations subsequent to the consummation of the share exchange in August 1998. Discussion of Pro Forma Results of Operations As discussed above, the historical financial statements included elsewhere herein do not reflect the results of operations of the businesses of CCIC, Crown and CTI (the "Businesses") on an aggregate basis for all of the periods presented. As a result, management believes that the historical financial statements included elsewhere herein do not, by themselves, provide investors with sufficient information to adequately assess the recent trends of the Businesses. The Company is providing the following discussion of the last two quarters' and the last nine months' pro forma results of operations, therefore, to supplement the historical financial information included elsewhere herein to assist investors in evaluating the Businesses' historical results of operations. The pro forma results of operations discussed below have been derived from the historical results of operations of the Company for the three months ended September 30, 1998 and June 30, 1998, and for the nine months ended September 30, 1998, and are adjusted to include CTI's results of operations for periods prior to the consummation of the share exchange with the shareholders of CTI. The pro forma results of operations do not purport to present the combined results of operations that the Businesses would have achieved had they been under common ownership and control during such periods, nor are they indicative of the results of operations that may be achieved in the future. The acquisitions of the acquired businesses (including CTI) by CCIC resulted in new bases of accounting whereby the assets and liabilities of the acquired businesses were adjusted to their fair values on their respective dates of acquisition pursuant to Accounting Principles Board Opinion No. 16. To the extent such adjustments resulted in charges to depreciation and amortization expense, such charges do not enter into the determination of costs of operations, general and administrative expenses or corporate development expenses. Discussion of Three Months Ended September 30, 1998 and June 30, 1998 Revenues for the three months ended September 30, 1998 were $54.3 million, an increase of $5.2 million from the three months ended June 30, 1998. This increase was primarily attributable to (i) a $3.3 million, or 8.8%, increase in site rental and broadcast transmission revenues, of which $3.0 million was attributable to CTI and $0.3 million was attributable to the Crown operations; and (ii) a $3.0 million increase in network services revenues from the Crown operations, partially offset by a $0.9 million decrease in network services revenues from CTI. The increase in site rental and broadcast transmission revenues at CTI was primarily due to additional digital broadcast transmission sites coming into service. The increase in site rental revenues at Crown was primarily due to the addition of 51 towers during the third quarter of 1998. Crown added 50 new tenant leases during the third quarter of 1998, compared to 43 new tenant leases during the second quarter of 1998. The increase in network services revenues at Crown was attributable to the completion of 148 tenant antenna installations during the third quarter of 1998, compared to 58 such installations during the second quarter of 1998. The decrease in network services revenues at CTI was attributable to a decrease in the number of completed projects during the third quarter of 1998 as compared to the second quarter of 1998. 54

The Company expects demand for third-party site acquisition services to continue to decline. In addition, demand for the Company's network services fluctuates from period to period and within periods. These fluctuations are caused by a number of factors, including the timing of customers' capital expenditures, annual budgetary considerations of customers, the rate and volume of wireless communications carriers' tower build-outs, timing of existing customer contracts and general economic conditions. While such demand fluctuates, the Company must incur certain costs, such as maintaining a staff of network services employees in anticipation of future contracts, even when there may be no current business. Consequently, the operating results of the Company's network services businesses for any particular period may vary significantly, and should not be considered as necessarily being indicative of longer-term results. Costs of operations for the three months ended September 30, 1998 were $24.0 million, an increase of $1.7 million from the three months ended June 30, 1998. This increase was primarily attributable to a $2.3 million increase in network services costs related to the Crown operations, offset by a $0.8 million decrease in site rental and broadcast transmission costs. Costs of operations for site rental and broadcast transmission as a percentage of site rental and broadcast transmission revenues decreased to 36.9% for the third quarter of 1998 from 42.2% for the second quarter of 1998; this improvement in margins was due to lower costs at CTI, where a greater proportion of engineering staff cost was incurred in connection with digital terrestrial transmission projects and capitalized. Costs of operations for network services as a percentage of network services revenues increased to 65.2% for the third quarter of 1998 from 55.6% for the second quarter of 1998, primarily due to lower margins from the Crown operations. Margins from the Crown network services operations decreased as a result of increasingly competitive market conditions. General and administrative expenses for the three months ended September 30, 1998 were $7.1 million, a decrease of $0.2 million from the three months ended June 30, 1998. General and administrative expenses as a percentage of revenues decreased to 13.0% for the third quarter of 1998 from 14.8% from the second quarter of 1998, primarily due to lower expenses at CTI. Discussion of Nine Months Ended September 30, 1998 Revenues for the nine months ended September 30, 1998 were $149.2 million, consisting of (i) $113.2 million in site rental and broadcast transmission revenues and (ii) $36.0 million in network services and other revenues. Site rental and broadcast transmission revenues from CTI amounted to $97.0 million, or 85.7% of total site rental and broadcast transmission revenues. Network services revenues from CTI, the Crown operations and the TEA operations amounted to $14.5 million, $13.3 million and $4.8 million, respectively. Costs of operations for the nine months ended September 30, 1998 were $66.4 million, consisting of (i) $44.3 million in site rental and broadcast transmission costs and (ii) $22.1 million in network services and other costs. Costs of operations for site rental and broadcast transmission as a percentage of site rental and broadcast transmission revenues were 39.1% (41.5% at CTI and 25.3% at Crown). Costs of operations for network services as a percentage of network services revenues were 61.4%. General and administrative expenses for the nine months ended September 30, 1998 were $20.0 million. General and administrative expenses as a percentage of revenues were 13.4%. Corporate development expenses for the nine months ended September 30, 1998 were $2.8 million, or 1.9% of revenues. Such costs are incurred primarily at the Company's corporate office. 55

This increase was primarily attributable to (i) a $21.7 million, or 322.0%, increase in site rental and broadcast transmission revenues, of which $12.3 million was attributable to CTI and $9.4 million was attributable to the Crown operations; (ii) a $10.4 million increase in network services revenues from the Crown operations, partially offset by a $2.2 million decrease in network services revenues from TEA; and (iii) $1.9 million in network services revenues from CTI. Costs of operations for the nine months ended September 30, 1998 were $22.6 million, an increase of $14.0 million from the nine months ended September 30, 1997. This increase was primarily attributable to (i) a $7.0 million increase in site rental and broadcast transmission costs, of which $4.3 million was attributable to CTI and $2.7 million was attributable to the Crown operations; (ii) a $6.4 million increase in network services costs related to the Crown operations, partially offset by a $2.3 million decrease in network services costs from TEA; and (iii) $1.9 million in network services costs from CTI. Costs of operations for site rental and broadcast transmission as a percentage of site rental and broadcast transmission revenues increased to 29.5% for the nine months ended September 30, 1998 from 21.1% for the nine months ended September 30, 1997 because of higher costs attributable to the CTI and Crown operations. Costs of operations for network services as a percentage of network services revenues decreased to 59.8% for the nine months ended September 30, 1998 from 62.5% for 56

the nine months ended September 30, 1997, primarily due to improved margins from the TEA operations. Margins from the Crown network services operations decreased for the nine months ended September 30, 1998 as a result of increasingly competitive market conditions. General and administrative expenses for the nine months ended September 30, 1998 were $15.0 million, an increase of $11.2 million from the nine months ended September 30, 1997. This increase was primarily attributable to (i) a $7.1 million increase in expenses related to the Crown operations; (ii) a $0.8 million increase in expenses related to the TEA operations; (iii) a $2.0 million increase in expenses at the Company's corporate office; and (iv) $0.8 million in expenses at CTI. General and administrative expenses as a percentage of revenues increased for the nine months ended September 30, 1998 to 28.8% from 21.0% for the nine months ended September 30, 1997 because of higher overhead costs as a percentage of revenues for Crown and TEA and the increase in costs at the Company's corporate office. Corporate development expenses for the nine months ended September 30, 1998 were $2.8 million, a decrease of $1.8 million from the nine months ended September 30, 1997. Corporate development expenses for the nine months ended September 30, 1997 include nonrecurring compensation charges associated with the CTI Investment of (i) $0.9 million for certain executive bonuses and (ii) the repurchase of shares of the Company's common stock from a member of its Board of Directors, which resulted in compensation charges of $1.3 million. Corporate development expenses for the nine months ended September 30, 1998 include discretionary bonuses related to the Company's performance totaling approximately $0.8 million for certain members of the Company's management. The Company has recorded non-cash compensation charges of $11.4 million related to the issuance of stock options to certain employees and executives. Such charges are expected to amount to approximately $1.6 million per year through 2002 and approximately $0.8 million in 2003. See "--Compensation Charges Related to Stock Option Grants". Depreciation and amortization for the nine months ended September 30, 1998 was $17.1 million, an increase of $13.8 million from the nine months ended September 30, 1997. This increase was primarily attributable to (i) an $8.0 million increase in depreciation and amortization related to the property and equipment, goodwill and other intangible assets acquired in the Crown Merger; (ii) $5.1 million of depreciation and amortization related to the property and equipment and goodwill from CTI; and (iii) a $0.3 million increase in depreciation and amortization related to the property and equipment and goodwill acquired in the TEA and TeleStructures Acquisitions. The equity in earnings (losses) of unconsolidated affiliate represents the Company's 34.3% share of CTI's net earnings (losses) for the periods from March 1997 through August 1998 (at which time the share exchange with CTI's shareholders was consummated). For the eight months ended August 31, 1998, after making appropriate adjustments to CTI's results of operations for such period to conform to generally accepted accounting principles of the United States, CTI had net revenues, operating income, interest expense (including amortization of deferred financing costs) and net income of $97.2 million, $18.6 million, $13.4 million and $6.0 million, respectively. Included in CTI's results of operations for such period are noncash compensation charges for approximately $3.8 million related to the issuance of stock options to certain members of CTI's management. Interest and other income for the nine months ended September 30, 1997 includes a $1.2 million fee received in March 1997 as compensation for leading the investment consortium which provided the equity financing for CTI. Interest income for the nine months ended September 30, 1998 resulted primarily from (i) the investment of excess proceeds from the sale of the Notes in November 1997; and (ii) the investment of the net proceeds from the Offering (see "--Liquidity and Capital Resources"). Interest expense and amortization of deferred financing costs for the nine months ended September 30, 1998 was $17.6 million, an increase of $13.2 million, or 302.5%, from the nine months ended September 30, 1997. This increase was primarily attributable to amortization of the original issue discount on the Notes and interest on CTI's indebtedness. Minority interests represent the minority shareholder's 20% interest in CTI's operations. 57

Comparison of Years Ended December 31, 1997 and 1996 Consolidated revenues for 1997 were $31.4 million, an increase of $25.2 million from 1996. This increase was primarily attributable to (i) a $5.4 million, or 96.1%, increase in site rental revenues, of which $4.2 million was attributable to the Crown operations and $0.7 million was attributable to the Puerto Rico operations; (ii) $10.4 million in network services revenues from TEA; and (iii) $7.2 million in network services revenues from the Crown operations. The remainder of the increase was largely attributable to higher revenues from SMR and microwave radio services in Puerto Rico and the monthly service fees received from CTI beginning in March 1997. Costs of operations for 1997 were $15.4 million, an increase of $14.1 million from 1996. This increase was primarily attributable to (i) $8.5 million of network services costs related to the TEA operations; (ii) $3.9 million of network services costs related to the Crown operations; and (iii) $0.9 million in site rental costs attributable to the Crown operations. Costs of operations for site rental as a percentage of site rental revenues decreased to 20.1% for 1997 from 23.0% for 1996 because of increased utilization of the towers located in the southwestern United States and Puerto Rico. Costs of operations for network services as a percentage of network services revenues were 64.4% for 1997, reflecting lower margins that are inherent in the network services businesses acquired in 1997. General and administrative expenses for 1997 were $6.8 million, an increase of $5.1 million from 1996. This increase was primarily attributable to $3.0 million of expenses related to the Crown operations and $1.4 million of expenses related to the TEA operations, along with an increase in costs of $0.2 million at CCIC's corporate office. General and administrative expenses as a percentage of revenues decreased for 1997 to 21.7% from 27.0% for 1996 because of lower overhead costs as a percentage of revenues for Crown and TEA. Corporate development expenses for 1997 were $5.7 million, an increase of $4.4 million from 1996. A substantial portion of this increase was attributable to nonrecurring compensation charges associated with the CTI Investment of (i) $0.9 million for certain executive bonuses and (ii) the repurchase of shares of CCIC's common stock from a member of its Board of Directors, which resulted in compensation charges of $1.3 million. The remaining $2.2 million of the increase in corporate development expenses was attributable to a higher allocation of personnel costs, along with an overall increase in such costs, associated with an increase in acquisition and business development activities. Depreciation and amortization for 1997 was $7.0 million, an increase of $5.7 million from 1996. This increase was primarily attributable to (i) $4.7 million of depreciation and amortization related to the property and equipment, goodwill and other intangible assets acquired in the Crown Merger; (ii) $0.5 million of depreciation and amortization related to the property and equipment and goodwill acquired in the TEA and TeleStructures Acquisitions; and (iii) $0.3 million resulting from twelve months of depreciation related to the property and equipment acquired in the Puerto Rico Acquisition. The equity in losses of unconsolidated affiliate of $1.1 million represents CCIC's 34.3% share of CTI's net loss for the period from March through December 1997. After making appropriate adjustments to CTI's results of operations for such period to conform to generally accepted accounting principles of the United States, CTI had net revenues, operating income, interest expense (including amortization of deferred financing costs) and net losses of $103.5 million, $16.5 million, $20.4 million and $3.3 million, respectively. Interest and other income for 1997 includes a $1.2 million fee received in March 1997 as compensation for leading the investment consortium which provided the equity financing for CTI, the impact on earnings of which was partially offset by certain executive bonuses related to the CTI Investment and included in corporate development expenses. Interest income for 1997 resulted primarily from the investment of excess proceeds from the sale of CCIC's Series C Convertible Preferred Stock in February 1997. Interest expense and amortization of deferred financing costs for 1997 was $9.3 million, an increase of $7.5 million, or 413.3%, from 1996. This increase was primarily attributable to (i) commitment fees related to an 58

unfunded interim loan facility related to the Crown Merger and an unfunded revolving credit facility; (ii) interest on notes payable to the former stockholders of Crown for a portion of the purchase price of the Crown Business; (iii) amortization of the original issue discount on the Notes; (iv) interest and fees associated with borrowings under CCIC's bank credit facility which were used to finance the Crown Merger on an interim basis; (v) interest on outstanding borrowings assumed in connection with the Crown Merger; and (vi) interest on borrowings under CCIC's bank credit facility which were used to finance the acquisition of the Puerto Rico System. Comparison of Years Ended December 31, 1996 and 1995 Consolidated revenues for 1996 were $6.2 million, an increase of $2.1 million, or 53.0%, from 1995. This increase was primarily attributable to (i) $0.6 million in site rental revenues attributable to the Puerto Rico operations; (ii) $0.6 million in site rental revenues resulting from the effect of a full year's activity for the operations of Spectrum (which was acquired in October 1995); (iii) an increase in site rental revenues of $0.3 million, or 6.9%, from the towers acquired from PCI; and (iv) $0.5 million in SMR and microwave radio services revenues attributable to the Puerto Rico operations. Costs of operations for 1996 were $1.3 million, an increase of $0.1 million, or 6.0%, from 1995. Additional costs in 1996 of $0.3 million attributable to the Puerto Rico operations were largely offset by decreased costs of $0.2 million associated with the towers acquired from PCI. Such towers were managed by PCI during 1995 under an agreement with CCIC, and the management fees charged to CCIC amounted to $0.6 million. CCIC began managing the towers on January 1, 1996. As a result of these factors, costs of operations as a percentage of revenues decreased to 21.0% in 1996 from 30.2% in 1995. General and administrative expenses for 1996 were $1.7 million, an increase of $0.9 million from 1995. This increase was primarily attributable to costs of $0.5 million and $0.1 million associated with the Spectrum and Puerto Rico Acquisitions, respectively, along with an increase in costs of $0.3 million, or 41.7%, at CCIC's corporate office. General and administrative expenses at CCIC's corporate office increased because of additional personnel costs and higher overhead resulting from CCIC's internal management of the PCI towers beginning in 1996. As a result of these factors, general and administrative expenses as a percentage of revenues increased to 27.0% in 1996 from 18.0% in 1995. Corporate development expenses for 1996 were $1.3 million, an increase of $1.1 million from 1995. This increase was primarily attributable to a higher allocation of personnel costs, along with an overall increase in such costs associated with an increase in acquisition and business development activities during the last half of 1996. Depreciation and amortization for 1996 was $1.2 million, an increase of $0.4 million from 1995. This increase was primarily associated with depreciation associated with towers purchased in the Puerto Rico Acquisition and goodwill created in the Spectrum Acquisition. Interest and other income for 1996 was $0.2 million, an increase of $0.1 million from 1995, primarily resulting from the investment of excess proceeds from the sale of CCIC's Series B Convertible Preferred Stock in July 1996. Interest expense and amortization of deferred financing costs for 1996 were $1.8 million, an increase of $0.7 million, or 58.6%, from 1995, primarily resulting from borrowings under CCIC's bank credit agreement which were used to finance the Puerto Rico Acquisition. CTI CTI's primary sources of revenues are from (i) the provision of analog and digital broadcast transmission services to the BBC and commercial broadcasters, (ii) the rental of antenna space on towers and (iii) the provision of network services, which includes broadcast consulting, network design and site selection, site acquisition, site development and antenna installation and site management and other services. 59

Broadcast transmission services revenues are received for both analog and digital transmission services. Monthly analog transmission revenues are principally received from the BBC under a contract with an initial 10-year term through March 31, 2007. Digital transmission services revenues from the BBC and ONdigital are recognized under contracts with initial terms of 12 years through November 15, 2010. Monthly revenues from these digital transmission contracts increase over time as the network rollout progresses. See "Business--U.K. Operations--Significant Contracts". Site rental revenues are received from other broadcast transmission service providers (primarily NTL) and wireless communications companies, including all four U.K. cellular operators (Cellnet, Vodafone, One2One and Orange). As of September 30, 1998, approximately 200 companies rented space on approximately 405 of CTI's 808 towers and rooftops. Site rental revenues are generally recognized on a monthly basis under lease agreements with original terms of three to twelve years. Such lease agreements generally require annual payments in advance, and include rental rate adjustment provisions between one and three years from the commencement of the lease. Site rental revenues are expected to become an tincreasing portion of CTI's total U.K. revenue base, and the Company believes that the demand for site rental from communication service providers will increase in line with the expected growth of these communication services in the United Kingdom. Network services revenues consist of (i) network design and site selection, site acquisition, site development and antenna installation (collectively, "network design and development") and (ii) site management and other services. Network design and development services are provided to (i) a number of broadcasting and related organizations, both in the United Kingdom and other countries; (ii) all four U.K. cellular operators; and (iii) a number of other wireless communications companies, including Dolphin and Highway One. These services are usually subject to a competitive bid, although a significant proportion result from an operator coming onto an existing CTI site. Revenues from such services are recognized on either a fixed price or a time and materials basis. Site management and other services, consisting of both network monitoring and equipment maintenance, are carried out in the United Kingdom for a number of emergency service organizations. Revenues for such services are received under contracts with original terms of between three and five years. They provide for fixed prices with respect to network monitoring and variable pricing dependent on the level of equipment maintenance carried out in a given period. Costs of operations for broadcast transmission services consist primarily of employee compensation and related benefits costs, utilities, rental payments under the Site-Sharing Agreement with NTL, circuit costs and repairs and maintenance on both transmission equipment and structures. Site rental operating costs consist primarily of employee compensation and related benefits costs, utilities and repairs and maintenance. The majority of such costs are relatively fixed in nature, with increases in revenue from new installations on existing sites generally being achieved without a corresponding increase in costs. Costs of operations for network services consist primarily of employee compensation and related benefits costs and on-site construction and materials costs. General and administrative expenses consist primarily of office occupancy and related expenses, travel costs, professional and consulting fees, advertising, insurance and employee training and recruitment costs. Corporate development expenses represent costs incurred in connection with acquisitions and development of new business initiatives. These expenses consist primarily of external professional fees related to specific activities and allocated compensation, benefits and overhead costs that are not directly related to the administration or management of CTI's existing lines of business. Depreciation and amortization charges relate to CTI's property and equipment (primarily towers, broadcast transmission equipment and associated buildings) and goodwill recorded in connection with the acquisition of the Home Service Transmission business from the BBC (the "BBC Home Service Transmission Business"). Depreciation of towers is computed with useful lives of 20 to 25 years; depreciation of broadcast transmission 60

equipment is computed with a useful life of 20 years; and depreciation of buildings is computed with useful lives ranging from 20 to 50 years. Amortization of goodwill is computed with a useful life of 20 years. The following information is derived from the Consolidated Profit and Loss Accounts of (i) CTI for periods subsequent to February 28, 1997 (the date of inception of CTI's operations) and (ii) the BBC Home Service Transmission Business for periods prior to that date. For purposes of the following discussion, CTI's results for the month ended March 31, 1997 have been combined with the results of the BBC Home Service Transmission Business for the eleven months ended February 27, 1997, and CTI's results for the nine months ended December 31, 1997 have been combined with its results for the three months ended March 31, 1998. The following discussion presents an analysis of such combined results for the twelve-month periods ended March 31, 1998 and 1997. Results for CTI are not comparable to results from the BBC Home Service Transmission Business due to differences in the carrying amounts of property and equipment and goodwill. As of December 31, 1997, CTI changed its fiscal year end for financial reporting purposes from March 31 to December 31; as such, the results for the three months ended March 31, 1998 are unaudited. CTI uses the U.K. pound sterling as the functional currency for its operations. The following amounts have been translated to U.S. dollars using the average Noon Buying Rate for each period. The following amounts reflect certain adjustments to present the results of operations in accordance with U.S. generally accepted accounting principles ("GAAP"). For the results of the BBC Home Service Transmission Business, such adjustments effect depreciation and amortization expense as a result of differences in the carrying amounts for property and equipment; for CTI, such adjustments effect (i) operating expenses as a result of differences in the accounting for pension costs, and (ii) interest expense as a result of the capitalization of interest costs in connection with constructed assets.

Comparison of Twelve Months Ended March 31, 1998 and Twelve Months Ended March 31, 1997 Consolidated revenues for the twelve months ended March 31, 1998 were $127.3 million, an increase of $5.1 million from the twelve months ended March 31, 1997. This increase was primarily attributable to (i) a $1.4 million increase in broadcast transmission services and site rental revenues and (ii) a $3.6 million increase in network services and other revenues. Revenues from the BBC for the twelve months ended March 31, 1998 amounted to $79.5 million, or 62.5% of total revenues, as compared to $85.5 million, or 70.0% of total revenues, for the twelve months ended March 31, 1997. Revenues from NTL for the twelve months ended March 31, 1998 amounted to $11.8 million, or 9.2% of total revenues. Network services revenues for the twelve months ended March 31, 1998 consisted of $10.6 million from network design and development services and $3.1 million from site management and other services. Costs of operations for the twelve months ended March 31, 1998 were $60.0 million, a decrease of $7.2 million from the twelve months ended March 31, 1997. This decrease was primarily attributable to a $7.4 million decrease in broadcast transmission services and site rental costs, partially offset by a $0.2 million increase in network services and other costs. Costs of operations as a percentage of revenues for broadcast transmission services and site rental were 47.5% for the twelve months ended March 31, 1998, as compared to 54.7% for the twelve months ended March 31, 1997. This decrease was attributable to (i) increases in site rental revenues from existing sites with little change in site operating costs; and (ii) the elimination, as of February 28, 1997, of certain costs recharged to the BBC Home Service Transmission Business by the BBC. Costs of operations as a percentage of revenues for network services and other were 44.2% for the twelve months ended March 31, 1998, as compared to 58.6% for the twelve months ended March 31, 1997. This decrease was attributable to (i) a higher proportion of broadcast consulting revenues, which result in higher margins than certain other network design and development services and (ii) the elimination, as of February 28, 1997, of certain costs recharged to the BBC Home Service Transmission Business by the BBC. Costs of operations for site rental and broadcast transmission for the twelve months ended March 31, 1998 includes non-cash compensation charges for $1.1 million related to the issuance of stock options to certain employees. General and administrative expenses for the twelve months ended March 31, 1998 were $8.6 million, an increase of $1.4 million from the twelve months ended March 31, 1997. As a percentage of revenues, general and administrative expenses were 6.8% and 5.9% for the twelve months ended March 31, 1998 and 1997, respectively. This increase was attributable to costs incurred by CTI as a separate enterprise which were not directly incurred by the BBC Home Service Transmission Business as a part of the BBC. Corporate development expenses for the twelve months ended March 31, 1998 relate primarily to costs incurred in connection with certain projects in Australasia and non-cash compensation charges for $1.8 million related to the issuance of stock options to certain executives. Depreciation and amortization for the twelve months ended March 31, 1998 was $37.4 million, an increase of $20.1 million from the twelve months ended March 31, 1997. Monthly charges for depreciation and amortization increased for periods subsequent to February 28, 1997 due to (i) a decrease in the estimated useful lives for certain transmission and power plant equipment from 25 to 20 years; and (ii) the amortization of goodwill recorded in connection with the acquisition of the BBC Home Service Transmission Business. Interest and other income for the twelve months ended March 31, 1998 resulted primarily from (i) the investment of excess proceeds from amounts drawn under CTI's bank credit facilities in February 1997; and (ii) the investment of cash generated from operations during the period. Interest expense and amortization of deferred financing costs for the twelve months ended March 31, 1998 was $24.2 million. This amount was comprised of (i) $4.9 million related to amounts drawn under the CTI Credit Facility; (ii) $15.6 million related to the CTI Bonds; and (iii) $3.7 million for the amortization of deferred financing costs. Interest expense and amortization of deferred financing costs of $1.4 million for the twelve months ended March 31, 1997 was attributable to amounts drawn under the CTI Credit Facility. The BBC Home Service Transmission Business did not incur any financing costs as a part of the BBC prior to February 28, 1997. 62

Liquidity and Capital Resources As of September 30, 1998, after giving pro forma effect to the Offering, the Company would have had consolidated cash and cash equivalents of $322.3 million (including $18.2 million at CTI), consolidated long-term debt of $425.3 million, consolidated redeemable preferred stock of $200.0 million and consolidated stockholders' equity of $745.1 million. In addition, on December 8, 1998, the Company entered into a Formation Agreement with BAM in which the Company agreed to contribute $250.0 million in cash to the Proposed JV. As of September 30, 1998, after giving pro forma effect to the Offering and the Proposed JV, the Company would have had consolidated cash and cash equivalents of $114.0 million (including $18.2 million at CTI), consolidated long-term debt of $605.3 million, consolidated redeemable preferred stock of $200.0 million and consolidated stockholders' equity of $942.1 million. As of November 1, 1998, CCI and its subsidiaries had no significant unused borrowing availability under the Senior Credit Facility, and CTI had unused borrowing availability under the CTI Credit Facility of approximately (Pounds)30.0 million ($51.0 million). As of September 30, 1998, after giving pro forma effect to the Offering, CCI and its subsidiaries and CTI and its subsidiaries would have had approximately $73.9 million and (Pounds)30.0 million ($51.0 million) of unused borrowing availability, respectively, under the Senior Credit Facility and the CTI Credit Facility. At formation of the joint venture, the Proposed JV will borrow $180.0 million under a committed $250.0 million credit facility. The Senior Credit Facility and the CTI Credit Facility require, and the Proposed JV Credit Facility will require, that the respective borrowers maintain certain financial covenants; in addition, all three credit facilities place restrictions on the ability of the Company and its subsidiaries to, among other things, incur debt and liens, pay dividends, make capital expenditures, undertake transactions with affiliates and make investments. These facilities also limit the ability of the Company's subsidiaries to pay dividends to CCIC. The Company's business strategy contemplates substantial capital expenditures in connection with (i) the expansion of its tower footprints by partnering with wireless communications carriers to assume ownership of their existing towers and by pursuing build-to-suit opportunities and (ii) to acquire existing transmission networks globally as opportunities arise. The exact amount of such capital expenditures will depend on the number of such opportunities that the Company is able to successfully consummate. In addition to the Proposed JV, the Company is currently pursuing other potential significant acquisitions, investments and joint venture opportunities that could require the Company to use all remaining proceeds of this Offering and to raise additional debt or equity financing in the near term. However, there can be no assurance that the Company will consummate any of these transactions in the near term or at all. See "Risk Factors--Broad Discretion in Application of Proceeds" and "Managing Integration and Growth". In addition, the Company anticipates that it will build, through the end of 1999, approximately 600 towers in the United States at a cost of approximately $135.0 million and approximately 200 towers in the United Kingdom at a cost of approximately $23.0 million. The Company also expects that the capital expenditure requirements related to the roll-out of digital broadcast transmission in the United Kingdom will be approximately (Pounds)100.0 million ($170.0 million). Capital expenditures were $77.7 million for the nine months ended September 30, 1998, of which $3.4 million was for CCIC, $62.1 million was for Crown and $12.2 million was for CTI. On a pro forma basis after giving effect to the Proposed JV, capital expenditures (excluding acquisitions) would have been $74.1 million for the year ended December 31, 1997 (of which $3.4 million would have been for CCIC and TEA, $27.1 million would have been for Crown, $17.6 million would have been for the Proposed JV and $26.0 million would have been for CTI), and $140.0 million for the nine months ended September 30, 1998 (of which $3.4 million would have been for CCIC, $62.1 million would have been for Crown, $2.5 million would have been for the Proposed JV and $72.0 million would have been for CTI). The Company has budgeted capital expenditures (excluding acquisitions) of $62.0 million for the three months ended December 31, 1998 and $337.0 million for the fiscal year ended December 31, 1999 (of which $37.0 million is budgeted for the Proposed JV). 63

To fund the execution of the Company's business strategy, the Company and its subsidiaries expect to use the net proceeds of the Offering, the borrowings available under the Senior Credit Facility, the borrowings available under the CTI Credit Facility and the remaining net proceeds from the 1997 Notes Offering and the IPO. Whether the Company utilizes the Senior Credit Facility and the CTI Credit Facility to finance expansion opportunities will depend upon a number of factors, including (i) the attractiveness of the opportunities, (ii) the time frame in which they are identified, (iii) the number of pre-existing projects to which the Company is committed and (iv) the Company's liquidity at the time of any potential opportunity. In the event the Company does not otherwise have cash available (from the net proceeds of the 1997 Notes Offering, the IPO, this Offering or otherwise), or borrowings under the Senior Credit Facility or the CTI Credit Facility have otherwise been utilized, when an opportunity arises, the Company would be forced to seek additional debt or equity financing or to forego the opportunity. In the event the Company determines to seek additional debt or equity financing, there can be no assurance that any such financing will be available (on commercially acceptable terms or at all) or permitted by the terms of the Company's existing indebtedness. To the extent the Company is unable to finance future capital expenditures, it will be unable to achieve its currently contemplated business strategy. For the nine months ended September 30, 1997 and 1998, the Company's net cash provided by (used for) operating activities was ($2.1 million) and $3.4 million, respectively. For the years ended December 31, 1995, 1996 and 1997, the Company's net cash provided by (used for) operating activities was $1.7 million ($0.5 million) and ($0.6 million), respectively. Since its inception, the Company has generally funded its activities (other than its acquisitions and investments) through excess proceeds from contributions of equity capital. The Company has financed its acquisitions and investments with the proceeds from equity contributions, borrowings under the Senior Credit Facility and the issuance of promissory notes to sellers. Since its inception, CTI has generally funded its activities (other than the acquisition of the BBC Home Service Transmission Business) through cash provided by operations and borrowings under the CTI Credit Facility. CTI financed the acquisition of the BBC Home Service Transmission Business with the proceeds from equity contributions and the issuance of the CTI Bonds. On December 21, 1998, the Company privately placed under Rule 144A and Regulation S of the Securities Act, 200,000 shares of its 12 3/4% Senior Exchangeable Preferred Stock due 2010, each share of which has a liquidation preference of $1,000. On August 18, 1998, the Company consummated the IPO at a price to the public of $13 per share. The Company sold 12,320,000 shares of its common stock and received proceeds of $151.0 million (after underwriting discounts of $9.1 million but before other expenses of the IPO, which totaled approximately $3.8 million). The net proceeds from the IPO were contributed to an unrestricted subsidiary and are currently invested in short-term investments. On August 18, 1998, the Company consummated a share exchange with certain shareholders of CTI, which increased the Company's ownership of CTI from approximately 34.3% to 80.0%. The Company issued 20,867,700 shares of its Common Stock and 11,340,000 shares of its Class A Common Stock, with such shares valued at an aggregate of $418.7 million (based on the price per share to the public in the IPO). The Company recognized goodwill of $343.9 million in connection with this transaction, which was accounted for as an acquisition using the purchase method. CTI's results of operations and cash flows are included in the consolidated financial statements for the period subsequent to the date the exchange was consummated. In July 1998, all of the holders of the Company's Senior Convertible Preferred Stock converted such shares into an aggregate of 9,629,200 shares of the Company's common stock. Upon consummation of the IPO, all of the holders of the Company's then-existing shares of Class A Common Stock, Class B Common Stock, Series A Convertible Preferred Stock, Series B Convertible Preferred Stock and Series C Convertible Preferred Stock converted such shares into an aggregate of 39,842,290 shares of the Company's common stock. In August and October of 1997, CCIC issued shares of its Senior Convertible Preferred Stock for aggregate net proceeds of $29.3 million and $36.5 million, respectively. The proceeds from the August issuance were used 64

to make a $25.0 million payment as part of the cash purchase price for the Crown Merger. On October 31, 1997, the Company entered into an amendment to the Senior Credit Facility. As amended, the Senior Credit Facility provides for available borrowings of $100.0 million and expires on December 31, 2004. On October 31, 1997, in connection with the October Refinancing, new borrowings under the Senior Credit Facility of $94.7 million, along with the proceeds from the October issuance of the Senior Convertible Preferred Stock, were used to repay the seller note issued in connection with the Crown Merger, to repay loans outstanding under a credit agreement at CCI and to pay related fees and expenses. CCIC used the net proceeds from the 1997 Notes Offering to repay substantially all of its outstanding indebtedness, including borrowings under the Senior Credit Facility, and to pay related fees and expenses. The balance of the net proceeds from the 1997 Notes Offering is being used for general corporate purposes. On October 8, 1998, the Company acquired all of the outstanding shares of Millennium Communications Limited ("Millennium") for aggregate consideration of $14.5 million, consisting of cash, CCIC common stock and the assumption of indebtedness. Millennium develops, owns and operates telecommunications towers and related assets in the United Kingdom. On the date of acquisition, Millennium owned 102 tower sites. Millennium is being operated as a subsidiary of CTI. On February 28, 1997, CTI used the proceeds from equity contributions and borrowings under the CTI Credit Facility to finance the acquisition of the BBC Home Service Transmission Business. On May 21, 1997, CTI used the net proceeds from the sale of the CTI Bonds to repay substantially all of the outstanding borrowings under the CTI Credit Facility. On July 17, 1998, the lenders (acting through Credit Suisse First Boston, as agent) under the CTI Credit Facility waived a provision in the CTI Credit Facility that would have required the repayment of the CTI Credit Facility concurrently with the listing of the Company's Common Stock. Prior to May 15, 2003, the Company's interest expense on the Notes will be comprised solely of the amortization of original issue discount. Thereafter, the Notes will require annual cash interest payments of approximately $26.7 million. Prior to December 15, 2003, the Company does not expect to pay cash dividends on the Exchangeable Preferred Stock or, if issued, cash interest on the Exchange Debentures. Thereafter, assuming all dividends or interest have been paid-in-kind, the Exchangeable Preferred Stock or, if issued, the Exchange Debentures will require annual cash dividend or interest payments of approximately $47.8 million. Annual cash interest payments on the CTI Bonds are (Pounds)11.25 million ($19.1 million). In addition, the Senior Credit Facility and the CTI Credit Facility will require periodic interest payments on amounts borrowed thereunder. The Company's ability to make scheduled payments of principal of, or to pay interest on, its debt obligations, and its ability to refinance any such debt obligations (including the Notes and the CTI Bonds), will depend on its future performance, which, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond its control. As discussed above, the Company's business strategy contemplates substantial acquisitions and capital expenditures in connection with the expansion of its tower footprints. There can be no assurance that the Company will generate sufficient cash flow from operations in the future, that anticipated revenue growth will be realized or that future borrowings, equity contributions or loans from affiliates will be available in an amount sufficient to service its indebtedness and make anticipated capital expenditures. The Company anticipates that it may need to refinance all or a portion of its indebtedness (including the Notes and the CTI Bonds) on or prior to its scheduled maturity. There can be no assurance that the Company will be able to effect any required refinancings of its indebtedness (including the Notes and the CTI Bonds) on commercially reasonable terms or at all. See "Risk Factors". Compensation Charges Related to Stock Option Grants During the period from April 24, 1998 through July 15, 1998, the Company granted options to employees and executives for the purchase of 3,236,980 shares of its common stock at an exercise price of $7.50 per share. Of such options, options for 1,810,730 shares vested upon consummation of the IPO and the remaining options 65

for 1,426,250 shares will vest at 20% per year over five years, beginning one year from the date of grant. In addition, the Company has assigned its right to repurchase shares of its common stock from a stockholder (at a price of $6.26 per share) to two individuals (including a newly-elected director) with respect to 100,000 of such shares. Since the granting of these options and the assignment of these rights to repurchase shares occurred subsequent to the date of the share exchange agreement with CTI's shareholders and at prices substantially below the price to the public in the IPO, the Company has recorded a non-cash compensation charge related to these options and shares based upon the difference between the respective exercise and purchase prices and the price to the public in the IPO. Such compensation charge will total approximately $18.4 million, of which approximately $10.6 million was recognized upon consummation of the IPO (for such options and shares which vested upon consummation of the IPO), and the remaining $7.8 million is being recognized over five years (approximately $1.6 million per year) through the second quarter of 2003. An additional $1.6 million in non-cash compensation charges will be recognized through the third quarter of 2001 for stock options issued to certain members of CTI's management prior to the consummation of the share exchange. Impact of Recently Issued Accounting Standards In February 1997, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards No. 128, Earnings per Share ("SFAS 128"). SFAS 128 establishes new standards for computing and presenting earnings per share ("EPS") amounts for companies with publicly held common stock or potential common stock. The new standards require the presentation of both basic and diluted EPS amounts for companies with complex capital structures. Basic EPS is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period, and excludes the effect of potentially dilutive securities (such as options, warrants and convertible securities) which are convertible into common stock. Dilutive EPS reflects the potential dilution from such convertible securities. SFAS 128 is effective for periods ending after December 15, 1997. The Company has adopted the requirements of SFAS 128 in its financial statements for the year ended December 31, 1997. In June 1997, the FASB issued Statement of Financial Accounting Standards No. 130, Reporting Comprehensive Income ("SFAS 130"). SFAS 130 establishes standards for the reporting and display of comprehensive income in a company's financial statements. Comprehensive income includes all changes in a company's equity accounts (including net income or loss) except investments by, or distributions to, the company's owners. Items which are components of comprehensive income (other than net income or loss) include foreign currency translation adjustments, minimum pension liability adjustments and unrealized gains and losses on certain investments in debt and equity securities. The components of comprehensive income must be reported in a financial statement that is displayed with the same prominence as other financial statements. SFAS 130 is effective for fiscal years beginning after December 15, 1997. The Company has adopted the requirements of SFAS 130 in its financial statements for the three months ended March 31, 1998. In June 1997, the FASB issued Statement of Financial Accounting Standards No. 131, Disclosures about Segments of an Enterprise and Related Information ("SFAS 131"). SFAS 131 establishes standards for the way that public companies report, in their annual financial statements, certain information about their operating segments, their products and services, the geographic areas in which they operate and their major customers. SFAS 131 also requires that certain information about operating segments be reported in interim financial statements. SFAS 131 is effective for periods beginning after December 15, 1997. The Company will adopt the requirements of SFAS 131 in its financial statements for the year ending December 31, 1998. In April 1998, the Accounting Standards Executive Committee of the American Institute of Certified Public Accountants issued Statement of Position 98-5, Reporting on the Costs of Start-Up Activities ("SOP 98-5"). SOP 98-5 requires that costs of start-up activities be charged to expense as incurred and broadly defines such costs. The Company has deferred certain costs incurred in connection with potential business initiatives and new geographic markets, and SOP 98-5 will require that such deferred costs be charged to results of operations upon its adoption. SOP 98-5 is effective for fiscal years beginning after December 15, 1998. The Company will adopt 66

the requirements of SOP 98-5 as of January 1, 1999. The cumulative effect of the change in accounting principle for the adoption of SOP 98-5 will result in a charge to results of operations in the Company's financial statements for the three months ended March 31, 1999; it is currently estimated that such charge will amount to approximately $2,300,000. Year 2000 Compliance We are in the process of conducting a comprehensive review of our computer systems to identify which of our systems will need to be modified, upgraded or converted to recognize and process dates after December 31, 1999 (the "Y2K problem"). The failure to correct a material Y2K problem could result in an interruption in, or failure of, certain normal business activities or operations. Such failures could materially and adversely affect our results of operations, liquidity and financial condition. Due to the general uncertainty inherent in the Y2K problem, resulting in part from the uncertainty of whether our suppliers and customers are addressing the Y2K problem, we are unable to determine at this time whether failures brought on by the Y2K problem will have a material adverse effect on our results of operations, liquidity or financial condition. We believe that, with the implementation of new business systems, the possibility of significant interruptions of normal operations should be reduced; however, we cannot guarantee that our business, financial condition and results of operations will not be materially adversely affected if we or our customers or contractors fail to resolve the Y2K problem in a timely manner. 67

THE EXCHANGE OFFER Purpose of the Exchange Offer In connection with the sale of the Old Preferred Stock, the Company entered into the Registration Rights Agreement with the Initial Purchasers, pursuant to which the Company agreed to use their best efforts to file with the Commission a registration statement with respect to the exchange of the Old Preferred Stock for a new series of exchangeable preferred stock with terms identical in all material respects to the terms of the Old Preferred Stock, except that the New Preferred Stock have been registered under the Securities Act and are issued free of any covenant regarding registration, including the payment of additional interest upon a failure to file or have declared effective an exchange offer registration statement or to consummate the Exchange Offer by certain dates. The Company is making the Exchange Offer in reliance on the position of the staff of the Commission as set forth in Exxon Capital Holdings Corp., SEC No- Action Letter (April 13, 1989), Morgan Stanley & Co. Inc., SEC No-Action Letter (June 5, 1991) and Shearman & Sterling, SEC No-Action Letter (July 2, 1993). However, the Company has not sought its own no-action letter, and there can be no assurance that the staff of the Commission would make a similar determination with respect to the Exchange Offer as in such other circumstances. Based upon these interpretations by the staff of the Commission, the Company believes that New Preferred Stock issued pursuant to this Exchange Offer in exchange for Old Preferred Stock may be offered for resale, resold and otherwise transferred by a holder thereof other than (i) a broker-dealer who purchased such Old Preferred Stock directly from the Company to resell pursuant to Rule 144A or any other available exemption under the Securities Act or (ii) a person that is an "affiliate" (as defined in Rule 405 of the Securities Act) of the Company without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such New Preferred Stock are acquired in the ordinary course of such holder's business and that such holder is not participating, and has no arrangement or understanding with any person to participate, in the distribution of such New Preferred Stock. Holders of Old Preferred Stock accepting the Exchange Offer will represent to the Company in the Letter of Transmittal that such conditions have been met. Any holder who participates in the Exchange Offer for the purpose of participating in a distribution of the New Preferred Stock may not rely on the position of the staff of the Commission as set forth in these no-action letters and would have to comply with the registration and prospectus delivery requirements, of the Securities Act in connection with any secondary resale transaction. A secondary resale transaction in the United States by a holder who is using the Exchange Offer to participate in the distribution of New Preferred Stock must be covered by a registration statement containing the selling securityholder information required by Item 507 of Regulation S-K of the Securities Act. Each broker-dealer that receives New Preferred Stock for its own account pursuant to the Exchange Offer must acknowledge that it acquired the Old Note, as a result of market-making activities or other trading activities and will deliver a prospectus in connection with any resale of such New Preferred Stock. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of New Preferred Stock received in exchange for Old Preferred Stock where such Old Preferred Stock were acquired by such broker-dealer as a result of market- making activities or other trading activities. The Letter of Transmittal states that by acknowledging and delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. The Company has agreed that for a period of 180 days after the Expiration Date, they will make this Prospectus available to broker-dealers for use in connection with any such resale. See "Plan of Distribution." Except as aforesaid, this Prospectus may not be used for an offer to resell, resale or other retransfer of New Preferred Stock. The Exchange Offer is not being made to, nor will the Company accept tenders for exchange from, holders of Old Preferred Stock in any jurisdiction in which the Exchange Offer or the acceptance thereof would not be in compliance with the securities or blue sky laws of such jurisdiction. 68

Terms of the Exchange Upon the terms and subject to the conditions of the Exchange Offer, the Company will, unless such Old Preferred Stock are withdrawn in accordance with the withdrawal rights specified in "Withdrawal of Tenders" below, accept any and all Old Preferred Stock validly tendered prior to 5:00 p.m., New York City time, on the Expiration Date. The date of acceptance for exchange of the Old Preferred Stock, and consummation of the Exchange Offer, is the Exchange Date, which will be the first business day following the Expiration Date (unless extended as described herein). The Company will issue, on or promptly after the Exchange Date, an aggregate liquidation preference of up to $200,000,000 of New Preferred Stock in exchange for an equal liquidation preference at maturity of outstanding Old Preferred Stock tendered and accepted in connection with the Exchange Offer. The New Preferred Stock issued in connection with the Exchange Offer will be delivered on the earliest practicable date following the Exchange Date. Holders may tender some or all of their Old Preferred Stock in connection with the Exchange Offer. The terms of the New Preferred Stock are identical in all material respects to the terms of the Old Preferred Stock, except that the New Preferred Stock have been registered under the Securities Act and are issued free from any covenant regarding registration, including the payment of additional interest upon a failure to file or have declared effective an exchange offer registration statement or to consummate the Exchange Offer by certain dates. The New Preferred Stock will evidence the same obligations as the Old Preferred Stock and will be issued under and be entitled to the same benefits under the Certificate of Designation as the Old Preferred Stock. As of the date of this Prospectus, $200,000,000 aggregate liquidation preference of the Old Preferred Stock is outstanding. In connection with the issuance of the Old Preferred Stock, the Company arranged for the Old Preferred Stock originally purchased by qualified institutional buyers to be issued and transferable in book-entry form through the facilities of The Depository Trust Company ("DTC"), acting as depositary. Except as described under "Book-Entry, Delivery and Form," the New Preferred Stock will be issued in the form of a global note registered in the name of DTC or its nominee and each holder's interest therein will be transferable in book-entry form through DTC. See "Book-Entry, Delivery and Form." Holders of Old Preferred Stock do not have any appraisal or dissenters' rights in connection with the Exchange Offer. Old Preferred Stock which are not tendered for exchange or are tendered but not accepted in connection with the Exchange Offer will remain outstanding and be entitled to the benefits of the Certificate of Designations, but will not be entitled to any registration rights under the Registration Rights Agreement. The Company shall be deemed to have accepted validly tendered Old Preferred Stock when, as and if the Company has given oral or written notice thereof to the Exchange Agent. The Exchange Agent will act as agent for the tendering holders for the purposes of receiving the New Preferred Stock from the Company. If any tendered Old Preferred Stock are not accepted for exchange because of an invalid tender, the occurrence of certain other events set forth herein or otherwise, certificates for any such unaccepted Old Preferred Stock will be returned, without expense, to the tendering holder thereof as promptly as practicable after the Expiration Date. Holders who tender Old Preferred Stock in connection with the Exchange Offer will not be required to pay brokerage commissions or fees or, subject to the instructions in the Letter of Transmittal, transfer taxes with respect to the exchange of Old Preferred Stock in connection with the Exchange Offer. The Company will pay all charges and expenses, other than certain applicable taxes described below, in connection with the Exchange Offer. See "--Fees and Expenses." 69

Expiration Date; Extensions; Amendments The term "Expiration Date" shall mean 5:00 p.m., New York City time, on , 1999, unless extended by the Company in its sole discretion (but in no event to a date later than , 1999), in which case the term "Expiration Date" shall mean the latest date and time to which the Exchange Offer is extended. The Company reserves the right, in its sole discretion (i) to delay accepting any Old Preferred Stock, to extend the Exchange Offer or to terminate the Exchange Offer and to refuse to accept Old Preferred Stock not previously accepted, if any of the conditions set forth below under "Conditions to the Exchange Offer" shall not have been satisfied and shall not have been waived by the Company (if permitted to be waived by the Company) and (ii) to amend the terms of the Exchange Offer in any manner. Any such delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by oral or written notice thereof to the registered holders. If the Exchange Offer is amended in a manner determined by the Company to constitute a material change, the Company will promptly disclose such amendment by means of a prospectus supplement that will be distributed to the registered holders of the Old Preferred Stock, and the Company will extend the Exchange Offer for a period of five to ten business days, depending upon the significance of the amendment and the manner of disclosure to the registered holders, if the Exchange Offer would otherwise expire during such five to ten business day period. In no event, however, shall the Expiration Date be later than , 1999. If the Company determines to make a public announcement of any delay, extension, amendment or termination of the Exchange Offer, the Company shall have no obligation to publish, advertise or otherwise communicate any such public announcement, other than by making a timely release to an appropriate news agency. Conditions to the Exchange Offer Notwithstanding any other term of the Exchange Offer, the Company will not be required to accept for exchange, or to exchange, any Old Preferred Stock for any New Preferred Stock, and may terminate or amend the Exchange Offer before the acceptance of any Old Preferred Stock for exchange, if: (a) any action or proceeding is instituted or threatened in any court or by or before any governmental agency with respect to the Exchange Offer which, in the Company's reasonable good faith judgment, would be expected to impair the ability of the Company to proceed with the Exchange Offer, or (b) any law, statute, rule of regulation is adopted or enacted, or any existing law, statute, rule or regulation is interpreted by the Commission or its staff, which, in the Company's reasonable good faith judgment, would be expected to impair the ability of the Company to proceed with the Exchange Offer. If the Company determines in its reasonable good faith judgment that any of the foregoing conditions exist, the Company may (i) refuse to accept any Old Preferred Stock and return all tendered Old Preferred Stock to the tendering holders, (ii) extend the Exchange Offer and retain all Old Preferred Stock tendered prior to the expiration of the Exchange Offer, subject, however, to the rights of holders who tendered such Old Preferred Stock to withdraw their tendered Old Preferred Stock which have not been withdrawn. If such waiver constitutes a material change to the Exchange Offer, the Company will promptly disclose such waiver by means of a prospectus supplement that will be distributed to the registered holders, and the Company will extend the Exchange Offer for a period of five to ten business days, depending upon the significance of the waiver and the manner of disclosure to the registered holders, if the Exchange Offer would otherwise expire during such five to ten business days. In no event, however, shall the Expiration Date be a date later than , 1999. Procedures for Tendering To tender in connection with the Exchange Offer, a holder must complete, sign and date the Letter of Transmittal, or a facsimile thereof, have the signatures thereon guaranteed if required by the Letter of Transmittal and mail or otherwise deliver such Letter of Transmittal or such facsimile, together with the Old Preferred Stock (unless such tender is being effected pursuant to the procedure for book-entry transfer described below) and any 70

other required documents, to the Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration Date. Any financial institution that is a participant in DTC's Book-Entry Transfer Facility system may make book-entry delivery of the Old Preferred Stock by causing DTC to transfer such Old Preferred Stock into the Exchange Agent's account in accordance with DTC's procedure for such transfer. Although delivery of Old Preferred Stock may be effected through book-entry transfer into the Exchange Agent's account at DTC, the Letter of Transmittal (or facsimile thereof), with any required signature guarantees and any other required documents, must, in any case, be transmitted to and received or confirmed by the Exchange Agent at its addresses set forth under the caption "Exchange Agent," below, prior to 5:00 p.m., New York City time, on the Expiration Date. DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH ITS PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT. The tender by a holder of Old Preferred Stock will constitute an agreement between such holder and the Company in accordance with the terms and subject to the conditions set forth herein and in the Letter of Transmittal. The method of delivery of Old Preferred Stock and the Letter of Transmittal and all other required documents to the Exchange Agent is at the election and risk of the holders. Instead of delivery by mail, it is recommended that holders use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure delivery to the Exchange Agent before the Expiration Date. No Letter of Transmittal of Old Preferred Stock should be sent to the Company. Holders may request their respective brokers, dealers, commercial banks, trust companies or nominees to effect the tenders for such holders. Any beneficial owner whose Old Preferred Stock are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and who wishes to tender should contact the registered holder promptly and instruct such registered holder to tender on such beneficial owner's behalf. If such beneficial owner wishes to tender on such owner's own behalf, such owner must, prior to completing and executing the Letter of Transmittal and delivery of such owner's Old Preferred Stock, either make appropriate arrangements to register ownership of the Old Preferred Stock in such owner's name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time. Signature on a Letter of Transmittal or a notice of withdrawal, as the case may be, must be guaranteed by an Eligible Institution (as defined below) unless the Old Preferred Stock tendered pursuant thereto are tendered (i) by a registered holder who has not completed the box entitled "Special Payment Instructions" or "Special Delivery Instructions" on the Letter of Transmittal, or (ii) for the account of an Eligible Institution. In the event that signatures on a Letter of Transmittal or a notice of withdrawal, as the case may be, are required to be guaranteed, such guarantee must be by a member firm of a registered national securities exchange or of the National Association of Securities Dealers, Inc., a commercial bank or trust company having an office or correspondent in the United States or an "eligible guarantor institution" within the meaning of Rule 17Ad-15 under the Exchange Act (an "Eligible Institution"). If the Letter of Transmittal is signed by a person other than the registered holder of any Old Preferred Stock listed therein, such Old Preferred Stock must be endorsed by such registered holder or accompanied by a properly completed bond power, in each case signed or endorsed in blank by such registered holder as such registered holder's name appears on such Old Preferred Stock. If the Letter of Transmittal or any Old Preferred Stock or bond powers are signed or endorsed by trustees, executors, administrators, guardians, attorney-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and unless waived by the Company, evidence satisfactory to the Company of their authority to so act must be submitted with the Letter of Transmittal. All questions as to the validity, form, eligibility (including time of receipt) and acceptance and withdrawal of tendered Old Preferred Stock will be determined by the Company in its sole discretion, which determination 71

will be final and binding. The Company reserves the absolute right to reject any and all Old Preferred Stock not properly tendered or any Old Preferred Stock whose acceptance by the Company would, in the opinion of U.S. counsel to the Company, be unlawful. The Company also reserves the right to waive any defects, irregularities or conditions of tender as to any particular Old Preferred Stock either before or after the Expiration Date. The Company's interpretation of the terms and conditions of the Exchange Offer (including the instructions in the Letter of Transmittal) will be final and binding, on all parties. Unless waived, any defects or irregularities in connection with tenders of Old Preferred Stock must be cured within such time as the Company shall determine. Although the Company intends to request the Exchange Agent to notify holders of defects or irregularities with respect to tenders of Old Preferred Stock, neither the Company, the Exchange Agent nor any other person shall have any duty or incur any liability for failure to give such notification. Tenders of Old Preferred Stock will not be deemed to have been made until such defects or irregularities have been cured or waived. Any Old Preferred Stock received by the Exchange Agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned by the Exchange Agent to the tendering holders, unless otherwise provided in the Letter of Transmittal, as soon as practicable following the Expiration Date. In addition, the Company reserves the right, as set forth above under the caption "Conditions to the Exchange Offer," to terminate the Exchange Offer. By tendering, each holder represents to the Company that, among other things, the New Preferred Stock acquired in connection with the Exchange Offer are being obtained in the ordinary course of business of the person receiving such New Preferred Stock, whether or not such person is the holder, that neither the holder nor any such other person has an arrangement or understanding with any person to participate in the distribution of such New Preferred Stock and that neither the holder nor any such other person is an "affiliate" (as defined in Rule 405 under the Securities Act) of the Company. If the holder is a broker-dealer which will receive New Preferred Stock for its own account in exchange of Old Preferred Stock, it will acknowledge that it acquired such Old Preferred Stock as the result of market making activities or other trading activities and it will deliver a prospectus in connection with any resale of such New Preferred Stock. See "Plan of Distribution." Guaranteed Delivery Procedures Holders who wish to tender their Old Preferred Stock and (i) whose Old Preferred Stock are not immediately available, or (ii) who cannot deliver their Old Preferred Stock, the Letter of Transmittal or any other required documents to the Exchange Agent, or cannot complete the procedure for book- entry transfer, prior to the Expiration Date, may effect a tender of their Old Preferred Stock if: (a) The tender is made through an Eligible Institution; (b) Prior to the Expiration Date, the Exchange Agent received from such Eligible Institution a properly completed and duly executed Notice of Guaranteed Delivery (by facsimile transmission, mail or hand delivery) setting forth the name and address of the holder, the certificate number or numbers of such Old Preferred Stock and the principal amount of Old Preferred Stock tendered, stating that the tender is being made thereby and guaranteeing that, within five business days after the Expiration Date, the Letter of Transmittal (or facsimile thereof) together with the certificate or certificates representing the Old Preferred Stock to be tendered in proper form for transfer (or confirmation of a book-entry transfer into the Exchange Agent's account at DTC of Old Preferred Stock delivered electronically) and any other documents required by the Letter of Transmittal will be deposited by the Eligible Institution with the Exchange Agent; and (c) Such properly completed and executed Letter of Transmittal (or facsimile thereof) as well as the certificate or certificates representing all tendered Old Preferred Stock in proper form for transfer (or confirmation of a book-entry transfer into the Exchange Agent's account at DTC of Old Preferred Stock delivered electronically) and all other documents required by the Letter of Transmittal are received by the Exchange Agent within five business days after the Expiration Date. 72

Withdrawal of Tenders Except as otherwise provided herein, tenders of Old Preferred Stock may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date. To withdraw a tender of Old Preferred Stock in connection with the Exchange Offer, a written facsimile transmission notice of withdrawal must be received by the Exchange Agent at its address set forth herein prior to 5:00 p.m., New York City time, on the Expiration Date. Any such notice of withdrawal must (i) specify the name of the person who deposited the Old Preferred Stock to be withdrawn (the "Depositor"), (ii) identify the Old Preferred Stock to be withdrawn (including the certificate number or numbers and principal amount of such Old Preferred Stock), (iii) be signed by the Depositor in the same manner as the original signature on the Letter of Transmittal by which such Old Preferred Stock were tendered (including any required signature guarantees) or be accompanied by documents of transfer sufficient to have the trustee register the transfer of such Old Preferred Stock into the name of the person withdrawing the tender, and (iv) specify the name in which any such Old Preferred Stock are to be registered, if different from that of the Depositor. All questions as to the validity, form and eligibility (including time of receipt) of such withdrawal notices will be determined by the Company, whose determination shall be final and binding on all parties. Any Old Preferred Stock so withdrawn will be deemed not to have been validly tendered for purposes of the Exchange Offer and no New Preferred Stock will be issued with respect thereto unless Old Preferred Stock so withdrawn are validly re- tendered. Any Old Preferred Stock which have been tendered but which are not accepted for exchange or which are withdrawn will be returned to the holder thereof without cost to such holder as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offer. Properly withdrawn Old Preferred Stock may be retendered by following one of the procedures described above under the caption "Procedures for Tendering" at any time prior to the Expiration Date. Exchange Agent ChaseMellon Shareholder Services, L.L.C. has been appointed as Exchange Agent in connection with the Exchange Offer. Questions and requests for assistance, requests for additional copies of this Prospectus or of the Letter of Transmittal should be directed to the Exchange Agent, at its offices at 2323 Bryan Street, Suite 2300, Dallas, Texas 75201. The Exchange Agent's telephone number is (214) 965-2220 and facsimile number is (214) 965-2233. Fees and Expenses The Company will not make any payment to brokers, dealers or others soliciting acceptances of the Exchange Offer. The Company will pay certain other expenses to be incurred in connection with the Exchange Offer, including the fees and expenses of the Trustee, accounting and certain legal fees. Holders who tender their Old Preferred Stock for exchange will not be obligated to pay any transfer taxes in connection therewith. If, however, New Preferred Stock are to be delivered to, or are to be issued in the name of, any person other than the registered holder of the Old Preferred Stock tendered, or if tendered Old Preferred Stock are registered in the name of any person other than the person signing the Letter of Transmittal, or if a transfer tax is imposed for any reason other than the exchange of Old Preferred Stock in connection with the Exchange Offer, then the amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted with the Letter of Transmittal, the amount of such transfer taxes will be billed directly to such tendered holder. Accounting Treatment The New Preferred Stock will be recorded at the same carrying value as the Old Preferred Stock as reflected in the Company's accounting records on the date of the exchange. Accordingly, no gain or loss for accounting purposes will be recognized by the Company upon the consummation of the Exchange Offer. Any expenses of the Exchange Offer that are paid by the Company will be charged against the Company's additional paid-in capital in accordance with generally accepted accounting principles. 73

Consequences of Failures to Properly Tender Old Preferred Stock in the Exchange Issuance of the New Preferred Stock in exchange for the Old Preferred Stock pursuant to the Exchange Offer will be made only after timely receipt by the Exchange Agent of such Old Preferred Stock, a properly completed and duly executed Letter of Transmittal and all other required documents. Therefore, holders of the Old Preferred Stock desiring to tender such Old Preferred Stock in exchange for New Preferred Stock should allow sufficient time to ensure timely delivery. The Company is under no duty to give notification of defects or irregularities with respect to tenders of Old Preferred Stock for exchange. Old Preferred Stock that are not tendered or that are tendered but not accepted by the Company, will, following consummation of the Exchange Offer, continue to be subject to the existing restrictions upon transfer thereof under the Securities Act and, upon consummation of the Exchange Offer, certain registration rights under the Registration Rights Agreement will terminate. In the event the Exchange Offer is consummated, the Company will not be required to register the remaining Old Preferred Stock. Remaining Old Preferred Stock will continue to be subject to the following restrictions on transfer: (i) the Remaining Old Preferred Stock may be resold only if registered pursuant to the Securities Act, if any exemption from registration is available thereunder, or if neither such registration nor such exemption is required by law, and (ii) the Remaining Old Preferred Stock will bear a legend restricting transfer in the absence of registration or an exemption therefrom. The Company does not currently anticipate that it will register the Remaining Old Preferred Stock under the Securities Act. To the extent that Old Preferred Stock are tendered and accepted in connection with the Exchange Offer, any trading market for Remaining Old Preferred Stock could be adversely affected. 74

INDUSTRY BACKGROUND General The Company owns, operates and manages wireless communications and broadcast transmission infrastructure, including towers and other communications sites, and also provides a full range of complementary network support services. Each of the wireless communications and broadcasting industries is currently experiencing a period of significant change. The wireless communications industry is growing rapidly as new wireless technologies are developed and consumers become more aware of the benefits of wireless services. Wireless technologies are being used in more applications and the cost of wireless services to consumers is declining. A significant number of new competitors in the wireless communications industry have developed as additional frequency spectrum has become available for a wide range of uses, most notably Personal Communications Services ("PCS") (known as "PCN" in the United Kingdom). This competition, combined with an increasing reliance on wireless communications by consumers and businesses, has led to an increased demand for higher quality, uninterrupted service and improved coverage, which, in turn, has led to increased demand for communications sites as new carriers build out their networks and existing carriers upgrade and expand their networks to maintain their competitiveness. These trends are affecting the wireless communications industry around the world. As the wireless communications industry has become more competitive, wireless communications carriers have sought operating and capital efficiencies by outsourcing certain network services and the build-out and operation of new and existing infrastructure and by co-locating transmission equipment with other carriers on multiple tenant towers. The need for co- location has also been driven by the growing trend by municipalities to slow the proliferation of towers. Further, the Company believes that there has been a fundamental shift in strategy among established wireless communications carriers relating to infrastructure ownership. The Company believes that in order to free up capital for the growth and management of their customer bases and expansion of their service offerings, such carriers are beginning to seek to sell their wireless communications infrastructure to, or establish joint ventures with, experienced infrastructure providers that have the ability to manage networks. The Company believes that those infrastructure providers with a proven track record of providing end-to-end services will be best positioned to successfully acquire access to such wireless communications infrastructure. The television broadcasting industry is experiencing significant change because of the impending widespread deployment of digital terrestrial television broadcasting (known as "DTV" in the United States and "DTT" in the United Kingdom). In the United States, the FCC has required the four major networks (ABC, CBS, NBC and Fox) to commence DTV broadcasts in the top ten markets by May 1999 and in the top 30 markets by November 1999. In the United Kingdom, pursuant to the Broadcasting Act 1996, six digital television transmission multiplexes, which permit the holders to transmit digital television broadcasting services, have been allocated. The Company successfully began commercial operation of the DTT network from an initial 22 transmission sites on November 15, 1998. Australia, France, Germany, Japan, Spain and Sweden are expected to be the next countries to introduce digital terrestrial television, followed by other European nations and later by developing countries. Many countries are expected to start to establish digital services within the next five years. The shift to digital transmission will require network design, development and engineering services and the significant enhancement of existing broadcast transmission infrastructure, including new transmission and monitoring equipment and the modification, strengthening and construction of towers (including over 1,000 tall towers in the United States). In addition, state-run broadcast transmission networks are continuing to be privatized throughout the world. The Company expects these trends to continue around the world in both the wireless communications and broadcasting industries. The Company believes that the next logical step in the outsourcing of infrastructure by wireless communications carriers and broadcasters will be the outsourcing of the operation of their towers and transmission networks, including the transmission of their signals, in much the same way as the BBC has done with its transmission network. This outsourcing will allow carriers to realize additional operating and capital 75

efficiencies and to focus on management of their customer bases and expansion of their service offerings. Management believes that such carriers will only entrust the transmission of their signals to those infrastructure providers, such as the Company, that have the ability to manage towers and transmission networks and a proven track record of providing end-to-end services to the wireless communications and broadcasting industries. Development of the Tower Industry United States. The U.S. wireless communications industry was transformed in the 1970s through the issuance of licenses by the FCC to provide high quality communications services to vehicle-mounted and hand-held portable telephones, pagers and other devices. The licensees built and began operating wireless networks that were supported by communication sites, transmission equipment and other infrastructure. In the early 1980s, the number of towers began to expand significantly with the development of more advanced wireless communications systems, particularly cellular and paging. Nevertheless, as additional towers were built by the wireless communications carriers, they often were built for a single purpose rather than as multiple tenant towers. Further, these towers were generally owned and maintained by carriers and were treated as corporate cost centers operated primarily for the purpose of transmitting or receiving such carriers' signals. During the mid-to-late 1980s, a number of independent operators of towers began to emerge. These independent tower operators focused on owning and managing towers with multiple tenants by adding lessees to existing and reconstructed towers. The Company believes the majority of these operators were small business owners with a small number of local towers and few services other than site rental. In the last five years, however, several larger independent tower operators have emerged as demand for wireless services has continued to grow and as additional high frequency licenses have been awarded for new wireless services (including PCS, narrowband paging and wireless local loop), each requiring networks with extensive tower infrastructure. These independent tower operators have sought to acquire smaller operators as well as suitable clusters of towers formerly owned by carriers and broadcasters in order to establish regional and national "tower footprints". Carriers expanding or building a network in a geographic area generally seek to lease space for antennas from a tower company with a strategically located cluster of towers and other communication sites in that area in order to efficiently and effectively establish service coverage in a given market. Today, towers are owned by a variety of companies, including wireless communications carriers, local and long distance telecommunications companies, broadcasting companies, independent tower operators, utilities and railroad companies. Despite the increasing demand for towers, the tower industry in the United States remains highly fragmented, with only a few independent tower operators owning a large number of towers. The pace of consolidation has begun to accelerate, however, as the larger independent operators continue to acquire small local operators and purchase towers from wireless communications companies. In addition, wireless communications carriers are building out new, or filling in existing, tower footprints for new and existing wireless services. Independent operators have also expanded into a number of associated network and communication site services, including the design of communication sites and networks, the selection and acquisition of tower and rooftop sites (including the resolution of zoning and permitting issues) and the construction of towers. Previously, carriers typically handled such services through in-house departments, and local nonintegrated service contractors focused on specific segments such as radio frequency engineering and site acquisition. Broadcast towers in the United States have typically been owned and operated on a fragmented basis. Typically, each network affiliate in each major market owns and operates its own television broadcasting tower. Local stations often have co-located their transmission equipment on these towers. Radio broadcast towers have also typically been erected by each station in a given market. Both television and radio broadcast towers have generally been constructed only for a single user and would require substantial strengthening to house new digital transmission equipment or other analog transmission equipment. As a result, similar to wireless communications towers, such towers historically have been treated as corporate cost centers operated primarily for the purpose of transmitting such broadcasters' signals. 76

United Kingdom. The first towers in the United Kingdom were built for the BBC's MF radio services. Additional towers were built in the 1940s to transmit HF radio services around the world. In the 1950s, both the BBC and Independent Television Authority (the predecessor of the Independent Broadcasting Authority) built towers for transmission of VHF television. The BBC used some of these towers and built additional towers in the 1960s for its VHF/FM radio services. UHF television started in 1964 and is now transmitted from some 1,100 towers. These towers have been built at a relatively constant rate (compared with wireless communications towers). The majority of tall towers were built in the 1950s and 1960s. The number of smaller towers built peaked at approximately 80 per year in the 1970s, reducing to approximately 25 per year in the early 1990s. The size and structure of towers varies widely due to location, antenna requirements and wind loading. Towers built primarily for broadcast transmission are often able to carry wireless communications antennas. Those that are currently incapable of doing so can be strengthened or replaced. Since 1982, the growth of wireless communications in the United Kingdom has led to significant expansion in the number of towers. Historically, there have been four major wireless communications carriers in the United Kingdom, each of which, in general, built towers for its own use, rather than as multiple tenant owners. These towers are owned and maintained by such carriers and, as in the United States, were treated as corporate cost centers operated primarily for the purpose of transmitting or receiving their signals. With the smaller geographic size of the United Kingdom, as compared to the United States, these carriers typically constructed their tower footprint to provide national coverage. Because of this nationwide build out, independent tower owners have not developed as they have in the United States. In addition to wireless communications providers, towers in the United Kingdom are owned by a variety of companies, such as telecommunications companies, utilities and railroad companies. Today, tower owners are upgrading their networks to provide more capacity and better service to their customers, while new entrants to the wireless communications market have sought to acquire rapid access to networks that provide national coverage. With the significant costs associated with the approval process for and the construction of new towers, and the significant capital requirements associated with ownership of tower infrastructure, wireless communications carriers have begun to look to third party tower owners to co-locate their antennas on existing towers, to build, own and operate new towers and to acquire such carriers' portfolios of existing towers. Characteristics of the Tower Industry Management believes that, in addition to the favorable growth and outsourcing trends in the wireless communications and broadcasting industries and high barriers to entry as a result of regulatory and local zoning restrictions associated with new tower sites, tower operators benefit from several favorable characteristics. The ability of tower operators to provide antenna sites to customers on multiple tenant towers provides them with diversification against the specific technology, product and market risks typically faced by any individual carrier. The emergence of new technologies, carriers, products and markets may allow independent tower operators to further diversify against such risks. Additionally, tower operators face increased "Not-In-My-Backyard" ("NIMBY") sentiment by communities and municipalities, which is reducing the number of opportunities for new towers to be built and driving the trend toward co-location on multiple tenant towers. The Company believes that independent tower operators also benefit from the contractual nature of the site rental business and the predictability and stability of monthly, recurring revenues. In addition, the site rental business has low variable costs and significant operating leverage. Towers generally are fixed cost assets with minimal variable costs associated with additional tenants. A tower operator can generally expect to experience increasing operating margins when new tenants are added to existing towers. The site rental business typically experiences low tenant churn as a result of the high costs that would be incurred by a wireless communications carrier were it to relocate an antenna to another site and consequently be forced to re-engineer its network. Moving a single antenna may alter the pre-engineered maximum signal coverage, requiring a reconfigured network at significant cost to maintain the same coverage. Similarly, a 77

television or FM broadcaster would incur significant costs were it to relocate a transmitter because, in order to avoid interruption of its transmissions, it would be necessary for the broadcaster to install and commence operations of a second broadcast site prior to ceasing signal transmission at the first site. In addition, regulatory problems associated with licensing the location of the new antenna with the FCC, in the United States, or being licensed for the location by the Radiocommunications Agency (the "RA") in the United Kingdom, may arise if the new location is at the edge of the wireless communication carrier's coverage area and if there is a possible adverse impact on other carriers. Municipal approvals are becoming increasingly difficult to obtain and may also affect the carrier's decision to relocate. The costs associated with network reconfiguration and FCC, RA and municipal approval and the time required to complete these activities may not be justified by any potential savings in reduced site rental expense. Trends in the Wireless Communications and Broadcasting Industries The Company's existing and future business opportunities are affected by the ongoing trends within the two major industries it serves, namely the wireless communications industry and the radio and television broadcasting industry. Each of these industries is currently experiencing a period of significant change that the Company believes is creating an increasing demand for communication sites and related infrastructure and network support services. Wireless Communications The wireless communications industry now provides a broad range of services, including cellular, PCS, paging, SMR and ESMR. The industry has benefitted in recent years from increasing demand for its services, and industry experts expect this demand to continue to increase. The Company believes that more communication sites will be required in the future to accommodate the expected increase in demand for wireless communications services. Further, the Company sees additional opportunities with the development of higher frequency technologies (such as PCS), which have a reduced cell range as a result of signal propagation characteristics that require a more dense network of towers. In addition, network services may be required to service the network build-outs of new carriers and the network upgrades and expansion of existing carriers. In addition to the increasing demand for wireless services and the need to develop and expand wireless communications networks, the Company believes that other trends influencing the wireless communication industry have important implications for independent tower operators. In order to speed new network deployment or expansion and generate efficiencies, carriers are increasingly co-locating transmission equipment with that of other network operators. The trend towards co-location has been furthered by the NIMBY arguments generated by local zoning/planning authorities in opposition to the proliferation of towers. Further, the number of competitors in wireless communications is increasing due to the auction of new spectrum and the deployment of new technologies. In this increasingly competitive environment, many carriers are dedicating their capital and operations primarily to those activities that directly contribute to subscriber growth, such as marketing and distribution. These carriers, therefore, have sought to reduce costs and increase efficiency through the outsourcing of infrastructure network functions such as communication site ownership, construction, operation and maintenance. Further, the Company believes that these carriers are beginning to seek to move their tower portfolios off their balance sheets through sales to, or joint ventures with, experienced tower operators who have the proven capability to provide end-to-end services to the wireless communications industry. United States. Current emerging wireless communications systems, such as PCS and ESMR, represent an immediate and sizable market for independent tower operators and network services providers as carriers build out large nationwide and regional networks. While several PCS and ESMR carriers have already built limited networks in certain markets, these carriers still need to fill in "dead zones" and expand geographic coverage. The Cellular Telecommunications Industry Association ("CTIA") estimates that, as of December 31, 1997, there were 51,600 antenna sites in the United States. The Personal Communications Industry Association ("PCIA") 78

estimates that the wireless communications industry will construct at least 100,000 new antenna sites over the next 10 years. As a result of advances in digital technology, ESMR operators, including Nextel, have also begun to design and deploy digital mobile telecommunications networks in competition with cellular carriers. In particular response to the increased competition, cellular operators are re-engineering their networks by increasing the number of sites, locating sites within a smaller radius, filling in "dead zones" and converting from analog to digital cellular service in order to manage subscriber growth, extend geographic coverage and provide competitive services. The demand for communication sites is also being stimulated by the development of new paging applications, such as e-mail and voicemail notification and two-way paging, as well as other wireless data applications. In addition, as wireless communications networks expand and new networks are deployed, the Company anticipates that demand for microwave transmission facilities that provide "backhaul" of traffic between communications sites to or from a central switching facility will also increase. Licenses are also being awarded, and technologies are being developed, for numerous new wireless applications that will require networks of communication sites. Future potential applications include those that will be deployed by the winners of licenses auctioned in February and March 1998 for local multi- point distribution services, including wireless local loop, wireless cable television, wireless data and wireless Internet access. Radio spectrum required for these technologies has, in many cases, already been awarded and licensees have begun to build out and offer services through new wireless systems. Examples of these systems include local loop networks operated by WinStar and Teligent, wireless cable networks operated by companies such as Cellular Vision and CAI Wireless, and data networks being constructed and operated by RAM Mobile Data, MTEL and Ardis. United Kingdom. As in the United States, the development of newer wireless communications technologies, such as PCN and digital Terrestrial Trunked Radio ("TETRA"), provides tower operators with immediate opportunities for site rental and new tower build out. The four existing national GSM/PCN carriers continue to fill in "dead zones" and add capacity to their networks. Also, the carrier that is using the TETRA standard, which is similar to GSM and has been adopted throughout Europe, is deploying a network across the United Kingdom. The United Kingdom's newly-licensed wireless local loop operators have the potential to be important site rental customers. Wireless local loop operators provide telephony services that are comparable to the range and quality of services delivered over the fixed wire networks. This technology is being rapidly deployed as a low-cost alternative to fixed networks. To date, a total of seven spectrum licenses have been awarded to companies planning to deploy wireless loop systems. In addition, the deployment of a new national digital PMR system (using the TETRA standard) for the use of the U.K. emergency services and the announced licensing in early 1999 by the U.K. Government of UMTS (Universal Mobile Telecommunications Service) networks, which will be the third generation of cellular, should create additional demand for antenna space and tower sites. Radio and Television Broadcasting General. There are currently three main transmission delivery methods for television and radio broadcasts: terrestrial, direct-to-home ("DTH") satellite and cable. Terrestrial technology, the most common delivery method in the United States and many other countries including the United Kingdom, relies on signal transmission by wireless telegraphy from a network of terrestrial transmitters for direct reception by viewers or listeners through an aerial system. Satellite signals are transmitted to satellites that then beam the signal over a target area (satellite footprint) for reception by a customer's satellite dish. A satellite customer must either purchase or rent a dish and a receiver/decoder and pay subscription fees to the relevant provider. A cable television customer typically rents a receiver/decoder and pays a subscription fee to receive services that are distributed to the home through co-axial or fiber optic cable. Until the 1990s, all three delivery methods used analog technology, which remains the most widespread technology in use today. In the early 1990s, digital technology was developed for radio and television broadcasting and has begun to be introduced for the transmission of radio and television signals. Digital transmission is now possible by terrestrial, satellite and cable methods. 79

Digital technology allows a number of signals to be compressed and interleaved, using a technical process called "multiplexing", before the combined signal is transmitted within a single frequency channel. This process makes the signal more robust, allowing the use of parts of the spectrum unavailable to analog. A greater quantity of audio-visual information can be transmitted with the same amount of frequency spectrum allowing higher resolution or multiple channels to be broadcast. At the point of reception, the compression and interleaving are decoded and individual signals recovered. Some of the principal advantages of digital compared to analog transmission include: (1) greater number, choice and flexibility of broadcasting services offered; (2) scope for greater interactivity on the part of viewers and listeners; (3) greater capacity for pay-television (subscription and pay-per- view) as well as free-to-air services; and (4) enhanced picture quality and sound. The development and timing of implementation of digital transmission technology to the general public is a function of several factors, including technological advancement, cost of equipment and conversion process, quality improvement of visual and sound transmission and demand for terrestrial bandwidth. The transition to digital transmission will involve additional costs to viewers and program and transmission service providers. Viewers will require additional equipment such as set-top boxes or digital televisions. Program providers have begun to re-equip their studios and production facilities with digital technology. United States. Prior to the introduction of digital transmission, the U.S. broadcasting industry had generally been a mature one in terms of demand for transmission tower capacity, although even then opportunities existed for independent tower operators to purchase transmission networks, manage them on behalf of broadcasters under long-term contracts and lease space on broadcasting towers to wireless communications carriers. The FCC-mandated introduction of digital television broadcasting will provide new opportunities for independent tower operators. The conversion of broadcasting systems from analog to digital technology will require a substantial number of new towers to be constructed to accommodate the new systems and analog equipment displaced from existing towers. Even with DTV transmissions, television station owners will continue to broadcast the existing analog signals for a number of years. Broadcasters that own their own tower infrastructure may elect to remove third-party tenants from their towers to make room for their own DTV equipment. These displaced tenants, and tower owners that are unable to remove existing third party tenants from their towers, will require new towers to accommodate their transmission equipment. The National Association of Broadcasters projects that by the year 2010 approximately 1,400 tall towers will be required to be built, strengthened or modified to support DTV, with 200 towers required in the top 50 markets within the next five years. Further, because of the need for broadcasters to purchase new transmission equipment to deploy DTV, they will have fewer resources to devote to the build out of new tower infrastructure. The Company believes that these circumstances, along with the relative scarcity of suitable sites and prevalent NIMBY attitudes, will allow experienced tower operators to build and operate multiple tenant broadcast towers to transmit DTV signals. These towers will also be attractive sites for the distribution of FM radio broadcasts. United Kingdom. The broadcasting industry in the United Kingdom has generally been a mature one in terms of demand for transmission tower capacity. Existing towers provide almost universal coverage for analog transmission, which remains the primary mode of transmission for television and radio programs in the United Kingdom. Most of the BBC's radio services, three Independent National Radio services and many local services are broadcast by analog terrestrial means. Some radio services are also available by satellite and cable for reception on fixed installations, but not portable or mobile sets. Digital television services in the United Kingdom were launched in 1998 from terrestrial transmitters (DTT) and satellite (DST). The Broadcasting Act of 1996 sets out a framework for the licensing of digital terrestrial multiplexes and an industry interest group has been established to coordinate the establishment of digital television in the United Kingdom. The British Government has allocated six multiplexes for DTT: two and one-half of these multiplexes were reserved for the BBC, ITV, Channel 4, S4C and Channel 5, three were awarded 80

to ONdigital (which is a joint venture of Carlton Communications PLC and Granada Group PLC) and the other one-half was awarded to S4C Digital Network. The Company has been awarded the digital transmission contract for the four multiplexes held by the BBC and ONdigital, while NTL has been awarded the digital transmission contract for the other two multiplexes. Build-out of digital terrestrial transmission equipment in the United Kingdom is being based on existing analog terrestrial infrastructure, including transmission sites and towers. In the initial phase of the rollout of digital terrestrial transmission equipment, 81 analog transmission sites and towers will be upgraded with new transmitters and associated systems required to support DTT. Digital broadcasts from these sites are expected to reach approximately 90% of the U.K. population. It is expected that additional sites will continue to be upgraded until the "vast majority" of viewers can receive digital broadcasts. While no formal timetable has been set for the discontinuation of analog terrestrial television broadcasting, the British Government has announced its intention to review, by 2002, the timing of analog "switch-off". When analog television transmission ceases, large amounts of frequency spectrum will be released. New uses for this spectrum have not yet been defined but applications are likely to include other digital broadcasting applications and mobile communications. The spectrum is inherently suitable for terrestrial transmission, so it is likely that existing towers will be used to provide many of the new services. In September 1995, the BBC launched the United Kingdom's first digital radio service, which is now broadcast to approximately 60% of the U.K. population from 29 transmission sites. Independent Local Radio licenses for additional digital radio multiplexes are expected to be issued by the end of 1999. To date, existing broadcast towers have been used as transmission sites for the BBC's digital radio service, and it is anticipated that existing towers also will be used for the independent services, often sharing the antennas used for the BBC's digital radio service. While digital radio has the advantage of using a single frequency network, which enables expanded geographic coverage as compared with the multiple frequency networks used for analog radio, to replicate the coverage of analog radio it will be necessary to broadcast digital radio from more sites than at present. Although detailed planning has not yet begun, it is expected that existing towers will provide the necessary sites. As with DTT, the Company believes that ownership of key broadcasting sites across the United Kingdom will allow an experienced operator to provide the infrastructure necessary to accommodate the growth in digital radio at minimum cost. 81

BUSINESS The Company is a leading domestic and international provider of wireless communications and broadcast transmission infrastructure and related services. The Company's business is to own, operate and manage wireless communications sites and broadcast transmission networks. In addition, the Company provides a full range of complementary services to its customers including (1) network design and site selection, (2) site acquisition, (3) site development and construction, (4) antenna installation and (5) network management and maintenance. As of September 30, 1998, the Company owned or managed 1,302 towers, including 548 towers in the United States and 754 towers in the United Kingdom. In addition, on October 8, 1998, the Company added 102 towers in the United Kingdom through its acquisition of Millenimum Communications Limited. Assuming the Company had formed the proposed joint venture with BAM, as of September 30, 1998, it would have owned an additional 1,427 towers, including 117 towers that we currently manage. These 1,427 towers form a significant portion of BAM's 850 MHZ wireless communications network in the eastern and southwestern United States. Based on its industry position and experience, the Company believes it is positioned to capitalize on global growth opportunities arising from: . the expansion of existing networks and the introduction of new networks in the wireless communications industry; . the consolidation of tower ownership generally, including the transfer of infrastructure ownership from major wireless communications carriers to independent infrastructure providers; . the ongoing privatization of state-run broadcast transmission networks around the world; and . the widespread introduction of digital transmission technology in the broadcasting industry. The Company's site rental business involves leasing antenna space to customers on towers and rooftops it owns or manages. The Company generally receives fees for installing a customer's equipment and antennas on a tower and also receives monthly rental payments from customers under site leases that typically range in term from three to five years. The Company's major site rental customers include Aerial Communications, AT&T Wireless, Bell Atlantic Mobile, BellSouth Mobility, Motorola, Nextel, PageNet and Sprint PCS in the United States and Cellnet, National Transcommunications Limited, One2One, Orange Personal Communications and Vodafone in the United Kingdom. The Company's broadcast transmission business includes both the transmission of analog and digital television and radio broadcasts and the construction of new multiple tenant broadcast towers. In the United Kingdom, the Company provides analog transmission services for two national television services, seven national radio services and 37 local radio stations through its network of 3,465 transmitters. These services are provided under long-term contracts with the BBC and two national commercial radio companies. In addition, the Company has long-term contracts to provide digital transmission services to the BBC and ONdigital. In the United States, the Company plans to build new multiple tenant broadcast towers in locations where additional tower capacity is required to accommodate new digital transmission equipment and analog transmission equipment displaced from existing towers. The Company has developed extensive expertise in its core site rental and broadcast transmission business. Further, its team of more than 300 engineers has substantial experience in providing end-to-end services, including (1) design of wireless communication and broadcast transmission networks, (2) radio frequency engineering, (3) site acquisition, (4) site development and construction and (5) antenna installation. The Company plans to leverage its technical expertise and operational experience to take advantage of the fundamental shift in strategy that is occurring among established wireless communications carriers relating to infrastructure ownership. Such carriers are beginning to seek to sell their wireless communications infrastructure to, or establish joint ventures with, experienced infrastructure providers that have the ability to manage networks. We believe that infrastructure providers with a proven track record of providing end-to-end services will be best positioned to successfully acquire access to such wireless communications infrastructure. 82

Background Founded in 1994, the Company acquired 127 towers located in Texas, Colorado, New Mexico, Arizona, Oklahoma and Nevada from PCI in 1995. Also in 1995, in order to expand its geographic coverage, scope of services and client base, the Company consummated the Spectrum Acquisition for a leading rooftop management and engineering firm that manages rooftop sites. The Spectrum Acquisition provided the Company with management revenues for 44 rooftop sites, as well as important relationships with carriers, and gave the Company an entry into the market for wireless network services. In 1996, the Company acquired from Motorola a strategic cluster of 14 towers located on mountaintops across Puerto Rico, as well as one rooftop site and an island-wide microwave and SMR system. The Puerto Rico Acquisition gave the Company a strategic tower footprint, and positioned the Company to be a leading independent tower operator in the Puerto Rican market. In addition, in July 1996, CCIC purchased an option to acquire 36% of TEA, which represented a significant step for the Company towards becoming a full service provider of wireless network services. TEA is a leading site acquisition firm offering carriers specialized expertise in site selection, site acquisition, zoning, permit procurement and project management. In May 1997, CCIC acquired all the outstanding shares of TEA. In June 1997, the Company purchased a minority interest in VISI, which intends to provide computerized geographic information for a variety of business applications (including site acquisition and telecommunication network design). In February 1997, CCIC, along with Candover Investments plc, TdF and Berkshire, formed CTI to purchase the BBC Home Service Transmission Business. Following the CTI Investment, the Company owned 34.3% of CTI. The BBC Home Service Transmission Business included ownership of approximately 730 towers in the United Kingdom and rights to locate broadcast transmission equipment on an additional 558 towers in the United Kingdom owned by NTL, CTI's primary competitor. In addition, CTI entered into a 10-year contract with the BBC to provide analog television and analog and digital radio transmission services in the United Kingdom. With the acquisition of the BBC Transmission Business, the Company, through its affiliation with CTI, gained access to an expertise in broadcast transmission upon which the Company believes it can capitalize in other markets. In August 1997, CCIC expanded its tower footprints and enhanced its network services offering in the United States by consummating the Crown Merger. The assets acquired through the Crown Merger included 61 owned towers and exclusive rights to lease antenna space on 147 other towers and rooftop sites, most of which are located in and around the greater Pittsburgh area, giving the Company a significant presence in that market. The remaining acquired Crown communication sites are located in Pennsylvania, West Virginia, Kentucky, Ohio and Delaware. The Crown assets included engineering and operational expertise and management experience. The Crown Merger also provided the Company with relationships with major wireless communications carriers such as Aerial Communications, AirTouch Cellular, Bell Atlantic Mobile, AT&T Wireless, PageNet, Nextel and Sprint PCS. On August 21, 1998, the Company consummated a share exchange with certain shareholders of CTSH. The result of this exchange was to increase the Company's equity interest in CTI to 80%. The remaining 20% of CTSH's shares are owned by TdF. Concurrently with the Roll-Up, the Company raised $151,043,200 in an initial public offering of its Common Stock. The Company's common stock is listed on the Nasdaq Stock Market's National Market under the symbol "TWRS". Based on a last sales price of $15 11/16 on December 7, 1998, the market value of our fully diluted common equity was approximately $1.75 billion. Business Strategy The Company's objective is to become the premier global provider of wireless communications and broadcast transmission infrastructure and related services. The Company's experience in establishing and expanding its existing tower footprints, its experience in owning and operating both analog and digital transmission networks, its significant relationships with wireless communications carriers and broadcasters and 83

its ability to offer customers its in-house technical and operational expertise, uniquely position it to capitalize on global growth opportunities. The key elements of the Company's business strategy are to: . Maximize Utilization of Tower Capacity. The Company is seeking to take advantage of the substantial operating leverage of its site rental business by increasing the number of antenna leases on its owned and managed communications sites. The Company believes that many of its towers have significant capacity available for additional antenna space rental and that increased utilization of its tower capacity can be achieved at low incremental cost. For example, prior to the Company's purchase of the BBC's broadcast transmission network in 1997, the rental of available antenna capacity on the BBC's premier tower sites was not actively marketed to third parties. The Company believes there is substantial demand for such capacity. In addition, the Company believes that the extra capacity on its tower footprints in the United States and the United Kingdom will be highly desirable to new entrants into the wireless communications industry. Such carriers are able to launch service quickly and relatively inexpensively by designing the deployment of their networks based on the Company's attractive existing tower footprints. Further, the Company intends to selectively build and acquire additional towers to improve the coverage of its existing tower footprints to further increase their attractiveness. The Company intends to use targeted sales and marketing techniques to increase utilization of and investment return on its existing, newly constructed and acquired towers. . Leverage Expertise of CCI and CTI Personnel to Implement Global Growth Strategy. The Company is seeking to leverage the skills of its personnel in the United States and the United Kingdom. The Company believes that its ability to manage networks, including the transmission of signals, will be an important competitive advantage in its pursuit of global growth opportunities. With its wireless communications and broadcast transmission network design and radio frequency engineering expertise, the Company is well positioned (1) to partner with major wireless communications carriers to assume ownership of their existing towers, (2) to provide build-to-suit towers for wireless communications carriers and broadcasters and (3) to acquire existing broadcast transmission networks that are being privatized around the world. . Partner with Wireless Communications Carriers to Assume Ownership of Their Existing Towers. In addition to the Proposed JV with BAM, the Company is continuing to seek to partner with other major wireless communications carriers to assume ownership of their existing towers directly or through joint ventures. The Company believes the primary criteria of such carriers in selecting a company to own and operate their wireless communications infrastructure will be the company's perceived capability to maintain the integrity of their networks, including their transmission signals. Therefore, the Company believes that those companies with a proven track record of providing end-to-end services will be best positioned to successfully acquire access to such wireless communications infrastructure. The Company believes that similar opportunities will arise globally as the wireless communications industry further expands. . Provide Build-to-Suit Towers for Wireless Communications Carriers and Broadcasters. As wireless communications carriers continue to expand and fill-in their service areas, they will require additional communications sites and will have to build new towers where co-location is not available. Similarly, the introduction of digital terrestrial television broadcasting in the United States will require the construction of new broadcast towers to accommodate new digital transmission equipment and analog transmission equipment displaced from existing towers. The Company is aggressively pursuing these build-to-suit opportunities, leveraging on its ability to offer end-to-end services. . Acquire Existing Broadcast Transmission Networks. In 1997, CTI successfully acquired the privatized domestic broadcast transmission network of the BBC. In addition, the Company is implementing the roll-out of digital television transmission services throughout the United Kingdom. As a result of this experience, the Company is well positioned to acquire other state-owned analog and digital broadcast transmission networks globally when opportunities arise. These state-owned broadcast transmission networks typically enjoy premier sites giving an acquirer the ability to offer unused antenna capacity to new and existing radio and television broadcasters and wireless communications carriers, as well as to install new technologies such 84

as digital terrestrial transmission services. In addition, the Company's experience in broadcast transmission services allows the Company to consider, when attractive opportunities arise, acquiring wireless transmission networks as well as the acquisition of associated wireless communications infrastructure. The Company is currently pursuing international acquisition and privatization opportunities. . Capitalize on Management Experience. The Company has assembled and will continue to build a strong management team that has extensive experience in the tower industry and in the management of broadcast transmission networks. Many of the senior executives have worked together for an extended period, which enables them to leverage their collective strengths in a rapidly changing industry environment. In addition, management is highly motivated to produce strong operating results based on their stock ownership in the Company. The Company CCIC is a holding company that conducts all of its business through its subsidiaries. CCIC's two principal operating subsidiaries are CCI, through which it conducts its U.S. operations, and CTI, through which it conducts its U.K. operations. The Company's interest in the proposed joint venture with BAM will be held and operated through a third subsidiary. U.S. Operations The Company's primary business focus in the United States is the leasing of antenna space on multiple tenant towers and rooftops to a variety of wireless communications carriers under long-term lease contracts. Supporting its competitive position in the site rental business, the Company maintains in- house expertise in, and offers its customers, infrastructure and network support services that include network design and communication site selection, site acquisition, site development and construction and antenna installation. The Company leases antenna space to its customers on its owned and managed towers. The Company generally receives fees for installing customers' equipment and antennas on a tower and also receives monthly rental payments from customers payable under site rental leases that generally range in length from three to five years. The Company's U.S. customers include such companies as Aerial Communications, AirTouch Cellular, Arch Communications, AT&T Wireless, Bell Atlantic Mobile, BellSouth Mobility, Cellular One, Federal Express, Lucent Technologies, Motorola, Nextel, Nokia, PageNet, Skytel, Sprint PCS and TSR Wireless, as well as private network operators and various federal and local government agencies, such as the Federal Bureau of Investigation, the Internal Revenue Service and the U.S. Postal Service. At September 30, 1998, the Company owned or managed 548 towers and 81 revenue producing rooftop sites in the United States and Puerto Rico. In addition, the Company had 1,286 rooftop sites under management throughout the United States that were not revenue producing but were available for leasing to customers. The Company's major U.S. tower footprints are located in western Pennsylvania (primarily in and around the greater Pittsburgh area), in the southwestern United States (primarily in western Texas), across Puerto Rico and along I-95 in North Carolina and South Carolina. The Company plans to enhance and expand its tower footprints by building and acquiring multiple tenant towers in locations attractive to site rental customers. To that end, the Company has developed, maintains and deploys for its own use extensive network design and radio frequency engineering expertise, as well as site selection, site acquisition and tower construction capabilities. The Company plans to leverage CCI's expertise and experience in building and acquiring new towers by entering into build-out, purchase or management contracts with various carriers and tower owners. For example, pursuant to an agreement with Nextel, as of September 30, 1998, the Company had constructed or purchased 43 sites, was in the process of constructing or receiving permits for an additional 63 sites, had identified 11 sites to purchase and has the option to construct or purchase up to 69 additional multiple tenant towers with Nextel as an anchor tenant along certain interstate corridors. In addition, pursuant to this agreement, the Company purchased 48 of Nextel's existing towers clustered in various markets, including Philadelphia, Houston, Dallas and San Antonio and has the option to purchase two additional towers. 85

Communication Site Footprints At September 30, 1998, the Company owned 419 towers and managed an additional 129 towers and 81 revenue producing rooftop sites in the United States and Puerto Rico. The Company is in the process of building 66 towers. The following table indicates, as of September 30, 1998, the type and geographic concentration of CCI's owned and managed towers and revenue producing rooftop sites: % of Number Total ------ ----- Towers: Pennsylvania................................................. 213 33.9% Texas........................................................ 154 24.5 New Mexico................................................... 34 5.4 Louisiana.................................................... 24 3.8 Mississippi.................................................. 21 3.3 Ohio......................................................... 19 3.0 West Virginia................................................ 18 2.9 Puerto Rico.................................................. 14 2.2 Arizona...................................................... 12 1.9 South Carolina............................................... 12 1.9 North Carolina............................................... 11 1.7 All Others................................................... 16 2.6 --- ----- Rooftops(a).................................................... 81 12.9 --- ----- Total...................................................... 629 100.0% === ===== - -------- (a) CCI manages an additional 1,286 rooftop sites throughout the United States that do not currently produce revenue but are available for leasing to its customers. The Company expects to significantly broaden its existing U.S. tower footprints and expand into new strategically clustered sites by building additional towers. To that end, the Company, through CCI, has developed and maintains and deploys for its own use extensive network design and radio frequency engineering expertise and tower construction capabilities. The Company plans to leverage CCI's network design expertise to build towers in areas where carriers' signals fail to transmit in their coverage area. The areas, commonly known as "dead zones", are attractive tower locations. Building a tower only after securing an anchor tenant, the Company usually has been able to add additional carriers that have the same "dead zone". The Company also plans to leverage CCI's expertise and experience in building new towers by entering into build-out or purchase contracts with various carriers, such as the Nextel Agreement. As of September 30, 1998, the Company had constructed 121 towers in western Pennsylvania, Ohio, Texas, South Carolina, Virginia, Indiana, West Virginia, Louisiana and North Carolina to enhance its regional presence in these areas. As part of the Nextel Agreement, the Company had the option to build or purchase up to 250 towers along interstate highways in the midwestern and eastern United States over the next two years. As of September 30, 1998, 43 of these sites had been completed, an additional 63 sites were in various stages of permitting and construction, 11 sites had been identified as candidates for purchase and 64 sites had been rejected because they did not meet the Company's investment criteria. Pursuant to the Nextel Agreement, 69 sites remain to be tendered to the Company. See "--Significant Contracts--Nextel Agreement". The Company plans to use the towers acquired in the Crown Merger as a model for the towers it intends to build when population density and perceived demand are such that the Company believes the economics of constructing such towers are justified. Management believes the Crown towers are superior to those of its competitors because of their capacity and quality engineering. The multiple tenant design of the Crown towers obviates the need for expensive and time consuming modifications to upgrade undersized towers, saving critical capital and time for carriers facing time-to-market constraints. Using only hot dipped galvanized structures 86

exceeding the standards of the American National Standards Institute, Electronics Industry Association and Telecommunications Industry Association, the Company builds towers capable of accommodating a large number of wireless antennas. The towers are also designed to easily add additional customers, and the equipment shelters are built to accommodate another floor for new equipment and air conditioning units when additional capacity is needed. The tower site is zoned for multiple carriers at the time the tower is constructed to allow new carriers to quickly utilize the site. In addition, the towers, equipment shelters and site compounds are engineered to protect and maintain the structural integrity of the site. Tower sites are designed to withstand severe wind, lightning and icing conditions, have shelters with exclusive security card access and are surrounded by ten foot barbed wire fences. The Company also plans to acquire towers in order to develop new tower footprints or to broaden its existing tower footprints. The Company believes that wireless communications carriers have begun to seek to sell, or establish joint ventures for the ownership of, their tower networks. See "Industry Background". The Company is actively seeking to enter into such arrangements with major wireless communications carriers. On a smaller scale, as part of the Nextel Agreement, the Company has purchased 48 of Nextel's existing towers and has the option to purchase an additional two towers. The Company believes that these towers will provide it with a portfolio of strategic clusters in Philadelphia, Houston, Dallas and San Antonio. The Company plans to continue to acquire additional towers from carriers, such as Nextel, and other independent tower operators as opportunities present themselves, although the Company currently has no agreements with regard to any such acquisitions. The Company generally believes it has significant capacity on a number of its towers in the United States and Puerto Rico. Many of the towers it acquired prior to the Crown Merger, however, may require significant modifications and improvements to raise them to the quality specifications of the Crown towers or to add additional customers. The Company intends to pursue these upgrades where it believes it can achieve appropriate returns to merit the necessary expenditure. Products and Services The Company's products and services can be broadly categorized as either site rental, network services or broadcast site rental and services. Network services provided through CCI include network design and site selection, site acquisition, site development and construction and antenna installation. Site Rental In the United States, the Company rents antenna space on its owned and managed towers and rooftops to a variety of carriers operating cellular, PCS, SMR, ESMR, paging and other networks. The Company's U.S. site rental business has its headquarters in Pittsburgh, with sales offices in Houston, Albuquerque, Philadelphia and San Juan. Tower Site Rental. The Company leases space to its customers on its owned and managed towers. The Company generally receives fees for installing customers' equipment and antennas on a tower (as provided in the Company's network services programs) and also receives monthly rental payments from customers payable under site leases. In the United States, the majority of the Company's outstanding customer leases, and the new leases typically entered into by the Company, have original terms of five years (with three or four optional renewal periods of five years each) and provide for annual price increases based on the Consumer Price Index. The Company also provides a range of site maintenance services in order to support and enhance its site rental business. The Company believes that by offering services such as antenna, base station and tower maintenance and security monitoring, it is able to offer quality services to retain its existing customers and attract future customers to its communication sites. The Company was the first site management company in the United States selected by a major wireless communications company to exclusively manage its tower network and market the network to other carriers for co-location. 87

Each of the Aerial Communications and Sprint PCS agreements has a 10-year master lease term through December 2006, with one 10-year and one five-year renewal period. Rents are adjusted periodically based on the cumulative Consumer Price Index. Nextel's master lease agreement with the Company has a 10-year master lease term through October 2006, with two 10-year renewal options. The Company has also entered into an independent contractor agreement with Nextel. The Bell Atlantic Mobile agreement has a 25-year master lease term through December 2020. The Company has also entered into a master lease agreement with Bell Atlantic whereby the Company has the right to lease antenna space to customers on towers controlled by Bell Atlantic Mobile. See "--Significant Contracts". The Company has significant site rental opportunities arising out of its agreements with Bell Atlantic Mobile and Nextel. In its lease agreement with Bell Atlantic Mobile, the Company has exclusive leasing rights for 117 existing towers and currently has sublessees on 59 of these towers in the greater Pittsburgh area. The lease agreement provides that CCI may sublet space on any of these towers to another carrier subject to certain approval rights of Bell Atlantic Mobile. To date, Bell Atlantic Mobile has never failed to approve a sublease proposed by CCI. If the Proposed JV is formed, it is expected that these 117 towers will be among the 1,427 towers to be contributed to the joint venture by BAM. Because the Company would maintain the right to put sublessees on those 117 towers, revenue resulting from the addition of new tenants on those towers would continue to be realized by the Company rather than the joint venture. In connection with the Nextel Agreement, as of September 30, 1998, the Company has the option to own and operate up to 69 additional towers. See "--Significant Contracts". Rooftop Site Rental. The Company is a leading rooftop site management company in the United States. Through its subsidiary, Spectrum, the Company develops new sources of revenue for building owners by effectively managing all aspects of rooftop telecommunications, including two-way radio systems, microwave facilities, fiber optics, wireless cable, paging and rooftop infrastructure services. Spectrum's staff includes radio frequency engineers, managers, technicians and licensing personnel with extensive experience. The Company generally enters into management agreements with building owners and receives a percentage of the revenues generated from the tenant license agreements. Specifically, the Company designs and contracts these sites, actively seeks multiple wireless communications carriers, prepares end-user license agreements, and 88

then manages and enforces the agreements. In addition, the Company handles billing and collections and all calls and questions regarding the site, totally relieving the building's management of this responsibility. Through Spectrum, the Company focuses on providing electronic compatibility for antennas, and maximization of revenue for building owners. In the United States, radio frequencies are assigned by the FCC but are not coordinated by proposed site. For this reason, Spectrum has developed its own computerized engineering program to determine the electronic compatibility of all users at each site. This program enables Spectrum to maximize site usage. Spectrum surveys each site and evaluates its location, height, physical and electronic characteristics, and its engineers prepare a computer analysis to determine the optimum location for different types of equipment and frequencies. Based on this analysis, potential site users are identified. In addition to the technical aspects of site management, the Company provides operational support for both wireless communications carriers looking to build out their wireless networks, and building owners seeking to out source their site rental activities. CCI stores and regularly updates relevant site data, such as the location of communications and broadcast equipment, into a database, which can be utilized to help wireless communications carriers plan and build out their networks. Network Services Through designing, building and operating its own communication sites, the Company, through CCI, has developed an in-house expertise in certain value- added services that it offers to the wireless communications and broadcasting industries. Because the Company views CCI as a turn-key provider with "end-to- end" design, construction and operating expertise, it offers its customers the flexibility of choosing between the provision of a full ready-to-operate network infrastructure or any of the component services involved therein. Such services include network design and site selection, site acquisition, site development and construction and antenna installation. Network Design and Site Selection. The Company has extensive experience in network design and engineering and site selection. While the Company maintains sophisticated network design services primarily to support the location and construction of Company-owned multiple tenant towers, the Company does from time to time provide network design and site selection services to carriers and other customers on a consulting contract basis. The Company's network design and site selection services provide customers with relevant information including recommendations regarding location and height of towers, appropriate types of antennas, transmission power and frequency selection and related fixed network considerations. In 1997, the Company provided network design services primarily for its own footprints and also for certain customers, including Triton Communications, Nextel, Aerial Communications and Sprint. These customers were typically charged on a time and materials basis. To capitalize on the growing concerns over tower proliferation, the Company has developed a program called "Network Solutions" through which it will attempt to form strategic alliances with local governments to create a single communications network in their communities. To date the Company's efforts have focused on western Pennsylvania, where it has formed alliances with three municipalities. These alliances are intended to accommodate wireless communications carriers and local public safety, emergency services and municipal services groups as part of an effort to minimize tower proliferation. By promoting towers designed for co-location, these alliances will reduce the number of towers in communities while serving the needs of wireless communications carriers and wireless customers. Site Acquisition. In the United States, the Company is engaged in site acquisition services for its own purposes and for third parties. Based on data generated in the network design and site selection process, a "search ring", generally of a one-mile radius, is issued to the site acquisition department for verification of possible land purchase or lease deals within the search ring. Within each search ring, Geographic Information Systems ("GIS") specialists select the most suitable sites, based on demographics, traffic patterns and signal characteristics. Once a site is selected and the terms of an option to purchase or lease the site are completed, a 89

survey is prepared and the resulting site plan is created. The plan is then submitted to the local zoning/planning board for approval. If the site is approved, the Company's construction department takes over the process of constructing the site. The Company provides solutions to the NIMBY dilemma of wireless companies by building more environmentally neutral and aesthetically acceptable towers. Designs have included a clock tower, bell tower and others that will allow communications companies to build in areas that otherwise would not permit a tower to be built. CCI has provided site acquisition services to several customers, including Aerial Communications, AirTouch Cellular, AT&T Wireless, Bell Atlantic Mobile, BellSouth Mobility, GTE Mobilnet, Nextel, Omnipoint, Pagemart, Sprint PCS and Teligent. These customers engage the Company for such site acquisition services on either a fixed price contract or a time and materials basis. Site Development and Construction and Antenna Installation. The Company has provided site development and construction and antenna installation services to the U.S. communications industry for over 14 years. The Company has extensive experience in the development and construction of tower sites and the installation of antenna, microwave dishes and electrical and telecommunications lines. The Company's site development and construction services include clearing sites, laying foundations and electrical and telecommunications lines, and constructing equipment shelters and towers. The Company has designed and built and presently maintains tower sites for a number of its wireless communications customers and a substantial part of its own tower network. The Company can provide cost-effective and timely completion of construction projects in part because its site development personnel are cross-trained in all areas of site development, construction and antenna installation. A varied inventory of heavy construction equipment and materials are maintained by the Company at its 45-acre equipment storage and handling facility in Pittsburgh, which is used as a staging area for projects in major cities in the eastern region of the United States. The Company generally sets prices for each site development or construction service separately. Customers are billed for these services on a fixed price or time and materials basis and the Company may negotiate fees on individual sites or for groups of sites. The Company has the capability and expertise to install antenna systems for its paging, cellular, PCS, SMR, ESMR, microwave and broadcasting customers. As this service is performed, the Company uses its technical expertise to ensure that there is no interference with other tenants. The Company typically bills for its antenna installation services on a fixed price basis. The Company's construction management capabilities reflect Crown's extensive experience in the construction of networks and towers. For example, Crown was instrumental in launching networks for Sprint PCS, Nextel and Aerial Communications in the Pittsburgh MTA. In addition, Crown supplied these carriers with all project management and engineering services which included antenna design and interference analyses. In 1997, the Company provided site development and construction and antenna installation services to approximately 21 customers in the United States, including Nextel, Sprint PCS, AT&T Wireless, Aerial Communications and Bell Atlantic Mobile. Broadcast Site Rental and Services The Company also provides site rental and related services to customers in the broadcasting industry in the United States. The launch of DTV in the United States will require significant expansion and modification of the existing broadcast infrastructure. Because of the significant cost involved in the construction or modification of tall towers, along with the large capital expenditures broadcasters will incur in acquiring digital broadcast equipment, management believes that the television broadcasting industry, which has historically been opposed to co-location and third party ownership of broadcast infrastructure, will seek to outsource tower ownership due to cost constraints. See "Industry Background". The Company is in the process of forming a joint venture with TdF to pursue tall tower build out and network ownership opportunities. This entity, which is expected to be approximately 70%-owned by the 90

Company, will seek to capitalize on CTI's and TdF's experience in the broadcast transmission market. Management's objective is to become a leader in the build out of the approximately 200 tall towers expected to be built in the United States over the next five years. Management believes that the Company's experience in providing digital transmission services in the United Kingdom will make the joint venture an attractive provider of broadcast services to the major networks and their affiliates. In addition, the joint venture will seek to partner with public broadcasting stations that own property zoned for tall towers, but that lack sufficient resources and expertise to build a tower. After reaching agreement with the public broadcasting station, the joint venture will attempt to co-locate on the tower the transmitters of major and medium-sized commercial broadcast television stations and high powered FM radio stations as well as wireless communications carriers. Electronic news gathering ("ENG") systems benefit from the towers and services offered by the Company. The ENG trucks, often in the form of local television station news vans with telescoping antennas on their roofs, send live news transmission back to the studio from the scene of an important event. Typically, these vans cannot transmit signals beyond about 25 miles. In addition, if they are shielded from the television transmitter site, they cannot make the connection even at close range. The Company has developed an ENG repeater system that can be used on many of its towers in western Pennsylvania and expects to develop similar systems in other markets in which it has or develops tower footprints. This system allows the ENG van to send a signal to one of the Company's local towers where the signal is retransmitted back to the television transmitter site. The retransmission of the signal from the Company's tower to the various television transmitter sites is done via a microwave link. The Company charges the station for the ENG receiver system at the top of its tower and also charges them for the microwave dish they place on its tower. The Company's ENG customers are affiliates of the NBC, ABC, CBS and Fox networks. The Company also has employees with considerable direct construction experience and market knowledge in the U.S. broadcasting industry, having worked with numerous television networks around the United States, and a number of other local broadcasting companies. The Company has installed master FM and television systems on buildings across the country. It has supervised the construction and operation of the largest master FM antenna facility in the United States and has engineered and installed two 2,000 foot broadcast towers with master FM antennas. Management believes that this experience may help the Company negotiate favorable antenna site lease rates and construction contracts for both tower and rooftop sites, and to gain an expertise in the complex issues surrounding electronic compatibility and RF engineering. Significant Contracts The Company has many agreements with telecommunications providers in the United States, including leases, site management contracts and independent contractor agreements. The Company's reciprocal leasing arrangements with Bell Atlantic Mobile, its agreement with Nextel and the BellSouth Site Marketing Agreement present unique opportunities for CCI to (i) acquire clusters of towers in new markets, (ii) expand its existing tower footprints by constructing multiple tenant towers with long-term anchor tenants and (iii) increase utilization of existing towers and rooftop sites. Bell Atlantic Mobile On December 29, 1995, the Company and Bell Atlantic Mobile entered into two separate 25-year master lease agreements relating to their towers in the Pittsburgh MTA, one establishing certain terms and conditions of Bell Atlantic Mobile's tenancy on the Company's towers and the other establishing certain terms and conditions of the Company's sale of tenancy to other parties on towers controlled by Bell Atlantic Mobile. In addition to providing site rental revenue to the Company, the master leases allow each of the Company and Bell Atlantic Mobile to sublease space on each other's towers in return for a percentage of the rental revenue generated thereby. Bell Atlantic Mobile's master lease of space on the Company's towers provides that Bell Atlantic Mobile's monthly site rental payments per tower depend on the size of the equipment installed on the tower, the size of 91

the equipment building and the number of antennas. Rents are adjusted periodically based on the Consumer Price Index. The Company performs all work at Bell Atlantic Mobile's sites for tenants, including antenna installation, grounding and foundations. Both of these master lease agreements included rights of first refusal relating to certain spaces on towers leased by one of the parties for which the other party had received a bona fide offer to buy. In connection with the Crown Merger, the parties amended these master lease agreements to eliminate the rights of first refusal, and Bell Atlantic waived any such rights under these agreements that otherwise would have arisen in connection with the Crown Merger. The Company also leases space on all of Bell Atlantic Mobile's towers in the Pittsburgh MTA (the "Bell Atlantic Agreement"). The terms and conditions of the Company's master lease of space on towers controlled by Bell Atlantic Mobile are substantially similar to Bell Atlantic Mobile's master lease with the Company. The Company may sublease space on a tower controlled by Bell Atlantic Mobile to another tenant, however, if the subtenant is to be AT&T, the Company must receive the written consent of Bell Atlantic Mobile. To date, the Company has 132 sublease contracts on Bell Atlantic Mobile-controlled towers. If the Proposed JV is formed, it is expected that these towers will be among the 1,427 towers to be contributed to the joint venture by BAM. Because the Company would maintain the right to put sublessees on these towers, revenue resulting from the addition of new tenants on those towers would continue to be realized by the Company rather than the joint venture. Nextel Agreement On July 11, 1997, in connection with Nextel's proposed merger with PCI, the Company and Nextel entered into the Nextel Agreement (the "Nextel Agreement"), which establishes the framework under which the Company and Nextel will conduct joint operations for the development of infrastructure within the Nextel markets described below. Under the first part of this agreement, the Company has purchased 48 existing towers from Nextel used in digital or analog transmission in the greater metropolitan areas of Denver and Philadelphia and in certain areas of the states of Texas and Florida, for a purchase price of approximately $10.0 million, and has the option to purchase two additional towers. In addition to the tower purchase, the Nextel Agreement provides that the Company has the exclusive right and option to (i) develop, construct, own and operate or (ii) purchase and operate, up to 250 new towers within selected metropolitan areas, including Dallas and Houston, and parts of the interstate highway corridors traversing the following states: Texas, Oklahoma, Louisiana, Arkansas, Mississippi, Alabama, Georgia, South Carolina, North Carolina, Tennessee, Kentucky, Virginia, Pennsylvania, New York, Ohio, Maryland and New Jersey. This option extends from July 1997 until a minimum of 250 potential sites have been tendered to the Company. At September 30, 1998, Nextel had tendered 181 sites to the Company, 117 of which met the Company's criteria for investing in towers and, therefore, were accepted by the Company. Of these 117 sites, 63 sites are in some stage of the permitting process, 11 sites have been identified as candidates for purchase and 43 sites have been completed. Nextel has not yet tendered 69 of the 250 towers. Nextel will perform all site acquisition work, including entering into agreements with the fee owners of sites. If the Company waives its option to construct or purchase new towers for an identified site tendered to it by Nextel, Nextel may construct the tower itself or contract with a third party for the construction. If the Company exercises its option to construct and own a tower, it will reimburse Nextel for all costs of such site acquisition work. If Nextel constructs a tower and the Company elects to purchase the constructed tower, the Company will reimburse Nextel for all site acquisition and construction costs associated with such towers. Following the completion of construction of each tower, Nextel and the Company will, pursuant to Nextel's master lease agreement, enter into a five-year lease contract with four five-year renewal periods, at the option of Nextel. Nextel has a one-time right of first refusal for a five-year period to lease additional space within one designated 20-foot section of each tower. If the Company elects to construct a new site, construction is to be completed within a 60-day construction period that will not begin prior to receipt of all regulatory permits and approvals (or a shorter period as mutually agreed). In the event that the Company fails to complete any site within the construction period, Nextel will be entitled to receive liquidated damages for each such failure. If the Company fails to commence or complete 92

construction or to complete the installation of towers and related equipment within the construction period, Nextel may exercise its option to purchase such site at cost (after giving the Company an opportunity to cure). Nextel may terminate the Nextel Agreement if the Company fails to complete construction within the prescribed construction period or if Nextel exercises its purchase option following certain construction delays by the Company for the greater of five towers or 5% of the aggregate number of total sites committed to within a rolling eight-month period. In addition, the Nextel Agreement provides that it may be terminated by Nextel upon the insolvency or liquidation of CCI and it may be terminated by the Company upon the insolvency or liquidation of Nextel. See "Risk Factors--Reliance on Nextel Agreement". BellSouth Site Marketing Agreement On June 25, 1998, CCI and BellSouth Mobility entered into a Site Marketing Agreement (the "BellSouth Site Marketing Agreement") pursuant to which CCI was designated as the exclusive marketing agent for BellSouth's tower sites in the State of Kentucky. CCI will facilitate the processing of site leases and customer equipment installation at BellSouth sites. By mutual agreement, CCI and BellSouth may extend the contract to cover other states. The initial term of the contract expires on January 31, 1999. After expiration of the initial term, unless BellSouth and CCI shall have entered into an agreement to form a permanent entity for the ownership, utilization and management of BellSouth's tower sites, BellSouth may, at its election, either (1) extend the term of the contract for five years or (2) grant CCI the right to purchase BellSouth's tower sites in Kentucky at their fair market value (but at not less than $75.0 million). If the contract is not extended or CCI elects not to purchase such tower sites, the contract will expire pursuant to its terms. Customers In both its site rental and network services businesses, the Company works with a number of customers in a variety of businesses including PCS, ESMR, paging and broadcasting. The Company works with both large national carriers such as Sprint PCS, Nextel, AT&T/Cellular One, Omnipoint and BellSouth Mobility, and smaller local regional or private operators such as Aerial Communications and Crescent Communications. For the nine months ended September 30, 1998, no customer accounted for more than 10.0% of CCI's revenues, other than Sprint PCS and Nextel, which accounted for approximately 10.6% and 30.4%, respectively, of CCI's consolidated revenues. Nextel revenues are expected to grow as CCI purchases Nextel towers and builds out Nextel interstate corridor sites. The following is a list of some of CCI's leading site rental customers by industry segment. Industry Selected Customers -------- ------------------ SMR/ESMR................ Nextel, SMR Direct Paging.................. AirTouch Cellular, PageNet, TSR Wireless PCS..................... Aerial Communications, Sprint PCS, Western Wireless Private Industrial Users.................. IBM, Phillips Petroleum Cellular................ AT&T Wireless, Bell Atlantic Mobile Governmental Agencies... FBI, INS, Puerto Rico Police Data.................... Ardis, RAM Mobile Data Broadcasting............ Hearst Argyle Television, Trinity Broadcasting Utilities............... Equitable Resources, Nevada Power Other................... WinStar Sales and Marketing CCI's sales and marketing personnel, located in Pittsburgh, Houston, Albuquerque, Atlanta, Philadelphia, Albany, San Juan, Puerto Rico and Sao Paulo, Brazil, target carriers expanding their networks, entering new markets, bringing new technologies to market and requiring maintenance or add-on business. All types of wireless service providers are targeted including broadcast, cellular, paging, PCS, microwave and two-way radio. CCI is also interested in attracting 9-1-1, federal, state, and local government agencies, as well as utility and 93

transportation companies to locate on existing sites. CCI's objective is to pre-sell capacity on CCI's towers by promoting sites prior to construction. Rental space on existing towers is also aggressively marketed and sold. CCI utilizes numerous public and proprietary databases to develop detailed target marketing programs directed at auction block license awardees, existing tenants and specific market groups. Mailings focus on regional build outs, new sites and services. The use of databases, such as those with information on sites, demographic data, licenses and deployment status, coupled with measured coverage data and RF coverage prediction software, allows CCI's sales and marketing personnel to target specific carriers' needs for specific sites. To foster productive relationships with its major existing tenants and potential tenants, CCI has formed a team of account relationship managers. These managers work to develop build-to-suit, site leasing services and site management opportunities, as well as ensure that customers' emerging needs are translated into new site products and services. The marketing department maintains CCI's visibility within the wireless communications industry through regular advertising and public relations efforts including actively participating in trade shows and generating regular press releases, newsletters and targeted mailings (including promotional flyers). CCI's promotional activities range from advertisements and site listings in industry publications to maintaining a presence at national trade shows. Potential clients are referred to CCI's Web site, which contains Company information as well as site listings. In addition, CCI's sites are listed on the Cell Site Express Web site. This Web site enables potential tenants to locate existing structures by latitude, longitude or address. Clients can easily contact CCI via e-mail through the Web site or Cell Site Express. CCI's network services capabilities are marketed in conjunction with its tower footprints. To follow up on targeted mailings and to cold-call on potential clients, CCI has established a telemarketing department. Telemarketers field inbound and outbound calls and forward leads to local sales representatives or relationship managers for closure. Local sales representatives are stationed in each cluster to develop and foster close business relationships with decision-makers in each customer organization. Sales professionals work with marketing specialists to develop sales presentations targeting specific client demands. In addition to a dedicated, full-time sales and marketing staff, a number of senior managers spend a significant portion of their efforts on sales and marketing activities. These managers call on existing and prospective customers and also seek greater visibility in the industry through speaking engagements and articles in national publications. Furthermore, many of these managers have been recognized as industry experts, are regularly quoted in articles and are called on to testify at local hearings and to draft local zoning ordinances. Public and community relations efforts include coordinating community events, such as working with amateur radio clubs to supply emergency and disaster recovery communications, charitable event sponsorship, and promoting charitable donations through press releases. Competition In the United States, the Company competes with other independent tower owners, some of which also provide site rental and network services; wireless communications carriers, which own and operate their own tower networks; service companies that provide engineering and site acquisition services; and other potential competitors, such as utilities, outdoor advertisers and broadcasters, some of which have already entered the tower industry. Wireless communications carriers that own and operate their own tower networks generally are substantially larger and have greater financial resources than the Company. The Company believes that tower location, capacity, price, quality of service and density within a geographic market historically have been and will continue to be the most significant competitive factors affecting tower rental companies. The Company also competes for acquisition and new tower construction opportunities with wireless communications carriers, site developers and other independent tower operating companies and believes that competition for tower site acquisitions will increase and that additional competitors will enter the tower market, some of which may have greater financial resources than the Company. 94

The following is a list of certain of the tower companies that compete with the Company in the United States: American Tower Corporation, Lodestar Communications, Motorola, OmniAmerica, Pinnacle Tower, SBA Communications, TeleCom Towers (an affiliate of Cox Communications), Unisite and SpectraSite. The following companies are primarily competitors for the Company's rooftop site management activities in the United States: AAT, APEX, Commsite International, JJS Leasing, Inc., Motorola, Signal One, Subcarrier Communications, Tower Resources Management and Unisite. The Company believes that the majority of its competitors in the site acquisition business operate within local market areas exclusively, while a small minority of firms appear to offer their services nationally, including SBA Communications Corporation, Whalen & Company and Gearon & Company (a subsidiary of American Tower Corporation). The Company offers its services nationwide and the Company believes it is currently one of the largest providers of site development services to the U.S. and international markets. The market includes participants from a variety of market segments offering individual, or combinations of, competing services. The field of competitors includes site acquisition consultants, zoning consultants, real estate firms, right-of-way consulting firms, construction companies, tower owners/managers, radio frequency engineering consultants, telecommunications equipment vendors (which provide turnkey site development services through multiple subcontractors) and carriers' internal staff. The Company believes that carriers base their decisions on site development services on certain criteria, including a company's experience, track record, local reputation, price and time for completion of a project. The Company believes that it competes favorably in these areas. Proposed Joint Venture On December 8, 1998, BAM, certain of the Transferring Partnerships, the Company and CCA Investment Corp., a wholly owned indirect subsidiary of the Company ("Company Sub"), entered into the Formation Agreement to form the Proposed JV to own and operate a significant majority of BAM's towers. The Company would own approximately 62.3% of the Proposed JV and BAM and certain of its affiliates would own the remaining 37.7% along with a 0.001% interest in the joint venture's operating subsidiary. For financial reporting purposes, the Company intends to consolidate the Proposed JV's results of operations and financial condition with its own. The day-to-day operations of the Proposed JV will be managed by the Company. The Proposed JV will actively seek to add additional tenants to its towers in order to increase its revenues. The Proposed JV will also construct and own new towers that are needed by BAM's wireless communications business. See "-- Build-to-Suit Agreement" and "--Global Lease". The Proposed JV will have regional offices that will be staffed primarily with employees of the Company to perform marketing, billing, operations and maintenance functions. Although the Proposed JV is expected to be formed during the first quarter of 1999, the Formation Agreement is subject to a number of significant conditions. There can be no assurance that the Proposed JV will be formed on the terms described in this document or at all. See "Risk Factors--The Proposed Joint Venture May Not Occur". 95

Communication Site Footprints The following table indicates, as of September 30, 1998, the type and geographic concentration of the Company's and the proposed joint venture's owned and managed towers and revenue producing rooftop sites: U.S. Total The Proposed After % of Towers: CCIC JV Proposed JV U.S. Total ------- ---- ------------ ----------- ---------- Pennsylvania........................ 213 212(a) 320 16.5 Texas............................... 154 43 197 10.2 South Carolina...................... 12 161 173 9.0 Arizona............................. 12 152 164 8.5 North Carolina...................... 11 137 148 7.6 New Jersey.......................... 1 142 143 7.4 New York............................ -- 119 119 6.1 Maryland............................ -- 108 108 5.6 Massachusetts....................... -- 81 81 4.2 New Mexico.......................... 34 36 70 3.6 Virginia............................ -- 57 57 2.9 Connecticut......................... -- 39 39 2.0 Louisiana........................... 24 13 37 1.9 Mississippi......................... 21 8 29 1.5 Delaware............................ -- 24 24 1.2 New Hampshire....................... -- 23 23 1.2 Georgia............................. -- 21 21 1.1 West Virginia....................... 18 13(b) 19 1.0 Ohio................................ 19 -- 19 1.0 Puerto Rico......................... 14 -- 14 0.7 Rhode Island........................ -- 13 13 0.7 All Others.......................... 15 25(c) 40 1.9 --- ----- ----- ----- 548 1,427(d) 1,858 95.8 Rooftops(e)......................... 81 -- 81 4.2 --- ----- ----- ----- U.S. Total........................ 629 1,427(d) 1,939 100.0% === ===== ===== ===== - -------- (a) Includes 105 towers currently managed by the Company.

(e) The Company manages an additional 1,286 rooftop sites throughout the United States that do not currently produce revenue but are available for leasing to its customers. The following descriptions of the agreements related to the Proposed JV are summaries of the material portions of those agreements. These descriptions are qualified in their entirety by reference to the complete texts of the agreements, each of which is available as set forth under the heading "Available Information". Formation Agreement Formation of the Proposed JV. Pursuant to the Formation Agreement, Company Sub will contribute $250.0 million in cash and approximately 15.6 million shares of common stock (valued at $197.0 million) of the Company to the Proposed JV. BAM and the Transferring Partnerships will transfer approximately 1,427 towers along with related assets and liabilities to the Proposed JV. The Proposed JV will borrow $180.0 million under a committed $250.0 million revolving credit facility. The joint venture will make a $380.0 million cash distribution to BAM. 96

Concurrently with the formation of the joint venture, BAM and the Proposed JV will enter into a master Build-to-Suit Agreement, a Global Lease and a transitional services agreement and the Company and the Proposed JV will enter into a services agreement. Terms and Conditions. In connection with its contribution of assets and liabilities to the Proposed JV, BAM is making certain representations and warranties to the Proposed JV concerning the contributed assets and liabilities. In general, the Proposed JV will have until June 30, 2000, to raise any claims for indemnification for breaches of the representations and warranties by BAM. However, BAM's indemnification obligations are subject to a number of significant limitations including a per occurrence deductible of $25,000, an aggregate deductible of $7.5 million and an absolute cap of $195.0 million. The formation of the Proposed JV is subject to a number of significant conditions. These conditions include: . accuracy of the representations and warranties of BAM and the Company; . receipt of bank financing by the Proposed JV; . receipt of certain third party consents required for the transfer of the tower assets to the Proposed JV; . receipt of regulatory approvals; . absence of litigation; . receipt of certain environmental studies; and . absence of any material adverse effect with respect to the business, assets, operations, conditions (financial or otherwise) or prospects of the Company and its subsidiaries taken as a whole. There can be no assurance that these conditions will be satisfied or waived. If they are not satisfied or waived, the Proposed JV may not be formed on the terms described in this document or at all. See "Risk Factors--The Proposed Joint Venture May Not Occur". Build-to-Suit Agreement In connection with the formation of the Proposed JV, BAM and the Proposed JV will enter into the Build-to-Suit Agreement. Pursuant to the Build-to-Suit Agreement and subject to certain conditions, BAM and the Proposed JV have agreed that (i) the next 500 towers to be built for BAM's wireless communications business will be constructed and owned by the Proposed JV and (ii) immediately thereafter the Proposed JV will have a right of first refusal to construct the next 200 additional towers to be built for BAM. BAM is required to submit these 700 site proposals to the Proposed JV during the five-year period following the formation of the joint venture; however, the five-year period will be extended for additional one-year periods, until 700 site proposals are submitted to the Proposed JV. The Proposed JV will be required to build towers in the general vicinity of the locations proposed by BAM. Upon completion of a tower, it will become subject to the Global Lease (as discussed below). Space not leased by BAM or its affiliates on each tower is available for lease by the Proposed JV to third parties. The Build-to-Suit Agreement sets out various time periods for BAM to identify its tower needs within certain search areas, and for the Proposed JV to locate sites and to thereafter complete site acquisition and development work, including permitting and construction. Global Lease In connection with the formation of the Proposed JV, BAM and the Proposed JV will enter into the Global Lease. All of the approximately 1,427 towers to be acquired by the Proposed JV from BAM and the Transferring Partnerships pursuant to the Formation Agreement, and all towers constructed by the Proposed JV pursuant to the Build-to-Suit Agreement, will be governed by the Global Lease. The average monthly rent paid by BAM on each of the 1,427 towers contributed to the Proposed JV by BAM will be approximately $1,850. Minimum monthly rents on the towers built pursuant to the Build-to-Suit Agreement will range from $1,250 to $1,833 97

depending on the region in which the tower is located. These rents may increase based on the amount of BAM's equipment to be installed at a site. Rents are subject to annual increase based on the consumer price index, subject to certain adjustments. For all sites, the initial lease term is ten years. BAM has the right to extend any lease for three additional five-year terms and one additional term of four years and eleven months. Each lease will automatically renew for an option term unless BAM notifies the Proposed JV at least six months before the then current term expires. Space not leased by BAM or its affiliates on each tower is available for lease by the Proposed JV to third parties. Operating Agreements In connection with the formation of the Proposed JV, BAM and Company Sub would enter into limited liability company operating agreements that will establish and govern the limited liability companies comprising the Proposed JV. Governance. The business and affairs of the Proposed JV will be managed by its managers under the supervision of a board of representatives. Each manager will be selected by Company Sub. Members of the board of representatives will be selected by each of BAM and Company Sub in proportion to their ownership interests in the Proposed JV. The board of representatives initially will have six members, with two selected by BAM and four selected by Company Sub. So long as BAM maintains at least a 5.0% interest in the Proposed JV, it will maintain the right to designate at least one member of the board of representatives. The managers will operate the Proposed JV on a day-to-day basis. In general, the managers will have the power and authority to take all necessary or appropriate actions to conduct the Proposed JV's business in accordance with its then current business plan. Actions requiring the approval of the board of representatives generally will be authorized upon the affirmative vote of a majority of the members of the board of representatives. However, the following actions will require the mutual consent of BAM and Company Sub, either by written consent or by the approval of representatives of each of BAM and Company Sub at a meeting of the board of representatives: . engaging in any business other than owning, acquiring, constructing, leasing and operating communications towers in the United States; . taking any voluntary action that would cause the Proposed JV to be insolvent or voluntarily entering into a bankruptcy proceeding; . incurring any debt other than the Proposed JV Credit Facility and ordinary course trade payables; . incurring any liens; . issuing any additional equity interests in the Proposed JV; . becoming liable with respect to contingent obligations such as guarantees or the obligation to make take-or-pay or similar payments; . failing to preserve the Proposed JV's existence under Delaware law or its qualification to do business in each jurisdiction in which such qualification is necessary or desirable; . mergers or consolidations; . sales of assets outside the ordinary course; . entry into contracts with affiliates except in the ordinary course and on an arm's-length basis; . any dividends or distributions; provided, if the Proposed JV has been dissolved and the Proposed JV Credit Facility has been repaid in full, BAM's consent will not be required; . the determination of the methodology to be used in calculating payments under the management agreement and the services agreement pursuant to which the Company will manage and provide services to the Proposed JV; 98

. approval of the business plan; . entry into contracts that (1) restrict the business activities of the Proposed JV in any geographic area, (2) contain exclusivity provisions, (3) are inconsistent with any of the agreements entered into in connection with the formation of the Proposed JV or (4) provide for the purchase or sale of goods or services involving an amount in excess of $10.0 million per year; and . exercising any voting rights with respect to the shares of common stock of the Company held by the Proposed JV; provided, if BAM and Company Sub do not agree as to how the shares should be voted, the shares will be voted pro rata with all shares of Common Stock of the Company voted on the matter. Restrictions on Transfers of Interests; Rights of First Refusal; Tag-Along Rights. Except for transfers to wholly owned affiliates, neither BAM nor Company Sub may transfer its interest in the Proposed JV to a third party unless it first offers its interest to the other on terms and conditions, including price, no less favorable than the terms and conditions on which it proposes to sell its interest to the third party. In addition, if BAM or Company Sub wishes to transfer its interest in the Proposed JV to a third party, the other party will have the right to require the third party, as a condition to the sale, to purchase a pro rata portion of its interest in the Proposed JV on the same terms and conditions, including price. BAM may only transfer its 0.001% interest in the operating subsidiary of the Proposed JV to its wholly owned affiliates or in connection with a merger or consolidation transaction to which BAM or Bell Atlantic Corporation is a party. Dissolution of the Proposed JV. BAM and the Company have agreed that upon a dissolution of the Proposed JV, in satisfaction of their respective interests in the Proposed JV, the Company would receive all the assets and liabilities of the Proposed JV other than the approximately 15.6 million shares of its common stock held by the Proposed JV and BAM would receive all of the shares of common stock of the Company held by the Proposed JV and a payment from the Company, equal to 14.0% of the fair market value of the assets and liabilities of the joint venture (other than the Company's common stock), to be made in cash or common stock of the Company (as elected by the Company). BAM would continue to retain its 0.001% interest in the joint venture's operating subsidiary. For so long as it retains such interest, the operations formerly included in the Proposed JV would remain subject to the operating restrictions set forth under "--Governance". A dissolution of the Proposed JV may be triggered (1) by BAM at any time following the third anniversary of the formation of the Proposed JV and (2) by the Company at any time following the fourth anniversary of its formation; however, if the Company triggers the dissolution prior to the seventh anniversary, it may be required to make additional cash payments to BAM. Transitional Services Agreement; Services Agreement In connection with the formation of the Proposed JV, BAM and the Proposed JV are expected to enter into a transitional services agreement pursuant to which BAM will provide the Proposed JV with services necessary to ensure a smooth transition of the business to the Proposed JV. In addition, the Company and the Proposed JV are expected to enter into the services agreement pursuant to which the Company will provide the Proposed JV with certain services. U.K. Operations The Company, through its 80% interest in CTI, owns and operates one of the world's most established television and radio transmission networks and is expanding its leasing of antenna space on its towers to a variety of wireless communications carriers. The Company provides transmission services for two BBC television services, six national BBC radio services (including the first digital audio broadcast service in the United Kingdom), 37 local BBC radio stations and two national commercial radio services through its network of transmitters, which reach 99.4% of the U.K. population. These transmitters are located on approximately 1,300 towers, more than half of which are Company- owned (or leased or licensed to it by third parties) and the balance of which are licensed to the Company under a site-sharing agreement (the "Site-Sharing Agreement") with 99

NTL, the Company's principal competitor in the United Kingdom. The Company has also secured long-term contracts to provide digital television transmission services to the BBC and ONdigital. See "--Significant Contracts". In addition to providing transmission services, the Company also leases antenna space on its transmission infrastructure to various communications service providers and provides telecommunications network installation and maintenance services and engineering consulting services. The Company's core revenue generating activity in the United Kingdom is the analog terrestrial transmission of radio and television programs broadcast by the BBC. CTI's business, which was formerly owned by the BBC, was privatized under the Broadcasting Act 1996 and sold to CTI in February 1997. At the time the BBC Home Service Transmission Business was acquired, CTI entered into a 10-year transmission contract with the BBC for the provision of terrestrial analog television and analog and digital radio transmission services in the United Kingdom. In the twelve months ended September 30, 1998, approximately 60% of CTI's consolidated revenues were derived from the provision of services to the BBC. Communication Site Footprints At September 30, 1998, the Company owned, leased or licensed 750 transmission sites on which it operated 754 towers, was constructing eight new towers on existing sites and had 49 site acquisition projects in process for new tower sites. The Company has 54 revenue producing rooftop sites that are occupied by the Company's transmitters but are not available for leasing to customers. The Company's sites are located throughout England, Wales, Scotland and Northern Ireland. The following table indicates, as of September 30, 1998, the type and geographic concentration of the Company's U.K. towers and rooftop sites. % of Number Total ------ ----- Towers: England...................................................... 442 54.7% Wales........................................................ 128 15.8 Scotland..................................................... 139 17.2 Northern Ireland............................................. 45 5.6 --- ----- 754 93.3 Rooftops....................................................... 54 6.7 --- ----- Total...................................................... 808 100.0% === ===== The Company expects to significantly expand its existing tower footprints in the United Kingdom by building and acquiring additional towers. The Company believes its existing tower network encompasses many of the most desirable tower locations in the United Kingdom for wireless communications. However, due to the shorter range over which communications signals carry (especially newer technologies such as PCN) as compared to broadcast signals, wireless communications providers require a denser footprint of towers to cover a given area. Therefore, in order to increase the attractiveness of its tower footprints to wireless communications providers, the Company will seek to build or acquire new communications towers. Using its team of over 300 engineers with state-of-the-art network design and radio frequency engineering expertise, the Company locates sites and designs towers that will be attractive to multiple tenants. The Company seeks to leverage such expertise by entering into build-to-suit contracts with various carriers, such as BT, Cable & Wireless Communications, Cellnet, Dolphin, Energis, Highway One, Ionica, One2One, Orange and Scottish Telecom, thereby securing an anchor tenant for a site before incurring capital expenditures for the site build out. As of September 30, 1998, the Company was building eight towers that it will own. In addition, the Company expects to make strategic acquisitions of existing communications sites (primarily those owned by wireless communications operators) in order to expand its infrastructure and to further leverage its site management experience. The Company believes that it generally has significant capacity on its towers in the United Kingdom. Although approximately 160 of its towers are poles with limited capacity, the Company typically will be able to 100

build new towers that will support multiple tenants on these sites (subject to the applicable planning process). The Company intends to upgrade these limited capacity sites where it believes it can achieve appropriate returns to merit the necessary capital expenditure. For example, in connection with a contract with Vodafone, the Company is upgrading 68 of these sites with limited capacity. See "--Significant Contracts--Vodafone". Approximately 59 of the Company's sites are used for Medium Frequency ("MF") broadcast transmissions. At this frequency, the entire tower is used as the transmitting antenna and is therefore electrically "live". Such towers are therefore unsuitable for supporting other tenant's communications equipment. However, MF sites generally have substantial ground area available for the construction of new multiple tenant towers. Products and Services Transmission Business Analog. For the three months ended September 30, 1998, CTI generated approximately 52% of its revenues from the provision of analog broadcast transmission services to the BBC. Pursuant to the BBC Analog Transmission Contract, the Company provides terrestrial transmission services for the BBC's analog television and radio programs and certain other related services (including BBC digital radio) for an initial 10-year term through March 31, 2007. See "--Significant Contracts". For the twelve months ended September 30, 1998, the BBC Analog Transmission Contract generated revenues of approximately (Pounds)49.0 million ($83.3 million) for the Company. In addition to the BBC Analog Transmission Contract, the Company has separate contracts to provide maintenance and transmission services for two national radio stations, Virgin Radio and Talk Radio. These contracts are for periods of eight years commencing from, respectively, March 31, 1993 and February 4, 1995. The Company owns all of the transmission equipment used for broadcasting the BBC's domestic radio and television programs, whether located on one of CTI's sites or on an NTL or other third-party site. As of September 30, 1998, CTI had 3,465 transmitters, of which 2,196 were for television broadcasting and 1,269 were for radio. A few of the Company's most powerful transmitters together cover the majority of the U.K. population. The coverage achieved by the less powerful transmitters is relatively low, but is important to the BBC's ambition of attaining universal coverage in the United Kingdom. This is illustrated by the following analysis of the population coverage of the Company's analog television transmitters: Combined population Number of sites (ranked by coverage) coverage ------------------------------------ ---------- 1 (Crystal Palace)............................................... 21% top 16........................................................... 79 top 26........................................................... 86 top 51........................................................... 92 all.............................................................. 99.4 All of the Company's U.K. transmitters are capable of unmanned operation and are maintained by mobile maintenance teams from 27 bases located across the United Kingdom. Access to the sites is strictly controlled for operational and security reasons, and buildings at 140 of the sites are protected by security alarms connected to CTI's Technical Operations Centre at Warwick. The Site- Sharing Agreement provides the Company with reciprocal access rights to NTL's broadcast transmission sites on which the Company has equipment. Certain of the Company's transmitters that serve large populations or important geographic areas have been designated as priority transmitters. These transmitters have duplicated equipment so that a single failure will not result in total loss of service but will merely result in an output-power reduction that does not significantly degrade the service to most viewers and listeners. 101

Digital. The Company has entered into contracts with the holders (including the BBC) of four of the six DTT multiplexes allocated by the U.K. government to design, build and operate their digital transmission networks. In connection with the implementation of DTT, new transmission infrastructure will be required. The Company is committed to invest approximately (Pounds)100.0 million ($170.0 million) for the build out of new infrastructure to support DTT over the next two years. By the year 2000, 81 transmission sites will need to be upgraded with new transmitters and associated systems to support DTT. Of these sites, 49 are owned by the Company with the remainder owned by NTL. An arrangement similar to that of the Site-Sharing Agreement is being negotiated to govern the particular issues arising out of the sharing of digital transmission sites between the Company and NTL. The Company successfully began commercial operation of the DTT network from an initial 22 transmission sites on November 15, 1998. The Company currently is the sole provider of transmission services for digital radio broadcasts in the United Kingdom. In September 1995, the BBC launched its initial DAB scheme over the Company's transmission network, and this service is now broadcast to approximately 60% of the U.K. population. A licence for an independent national digital radio network was awarded to the Digital One consortium during 1998 and it is expected that this service will commence during 1999. the company is in negotiations to provide accommodation and access to masts and antennas at 24 transmission sites to support the launch of Digital One. In addition, local digital radio licences will be awarded during 1999. The company believes it is well positioned to become the transmission service provider to the winners of such licences. Site Rental The BBC transmission network provides a valuable initial footprint for the creation of wireless communications networks. As of September 30, 1998, approximately 200 companies rented antenna space on approximately 405 of CTI's 808 towers and rooftops. These site rental agreements have normally been for three to 12 years and are generally subject to rent reviews every three years. Site sharing customers are generally charged annually in advance, according to rate cards that are based on the antenna size and position on the tower. The Company's largest site rental customer in the United Kingdom is NTL under the Site-Sharing Agreement. This agreement generated (Pounds)551,000 ($936,424) of site rental revenue in June 1998. The Company also provides a range of site maintenance services in order to support and enhance its U.K. site rental business. The Company believes that by offering services such as antenna, base station and tower maintenance and monitoring, it is able to offer quality services to retain its existing customers and attract future customers to its communications sites. The Company complements its U.K. transmission experience with its site management experience in the United States to provide customers with a top-of-the-line package of service and technical support. The following table describes the Company's top ten revenue producing towers in the United Kingdom: CTI's CTI's September September Number of 1998 1998 Height Tenant Monthly Monthly Name Location (ft) Leases Revenue Revenue ---- ------------ ------ --------- --------------- --------- Brookmans Park..........

Other than NTL, CTI's largest (by revenue) site rental customers consist mainly of wireless communications carriers such as Cellnet, One2One, Orange and Vodafone. Revenues from these non-BBC sources are expected to become an increasing portion of CTI's total U.K. revenue base, as the acquired BBC Home Service Transmission Business is no longer constrained by governmental restrictions on the BBC's commercial activities. The Company believes that the demand for site rental from communication service providers will increase in line with the expected growth of these communication services in the United Kingdom. The Company has master lease agreements with all of the major U.K. telecommunications site users including BT, Cable & Wireless Communications, Cellnet, Dolphin, Energis, Highway One, One2One, Orange, Scottish Telecom and Vodafone. These agreements typically specify the terms and conditions (including pricing and volume discount plans) under which these customers have access to all sites within the Company's U.K. portfolio. Customers make orders for specific sites using the standard terms included in the master lease agreements. As of September 30, 1998 there were approximately 250 applications in process for installations at existing sites under such agreements. Network Services CTI provides broadcast and telecommunications engineering services to various customers in the United Kingdom. All the BBC Home Service Transmission Business employees were retained by the Company upon CTI's acquisition. Accordingly, the Company has engineering and technical staff of the caliber and experience necessary not only to meet the requirements of its current customer base, but also to meet the challenges of developing digital technology. Within the United Kingdom, CTI has worked with several telecommunications operations on design and build projects as they roll-out their networks. CTI has had success in bidding for broadcast consulting contracts, including, over the last three years, in Thailand, Taiwan, Poland and Sri Lanka. With the expertise of its engineers and technical staff, the Company is a turn-key provider to the wireless communications and broadcast industries. The Company can provide customers with a ready-to-operate network infrastructure or any of the component services involved therein. Such services include network design and site selection, site acquisition, site development and antenna installation. Network Design and Site Selection. The Company has extensive experience in network design and engineering and site selection. While the Company maintains sophisticated network design services primarily to support the location and construction of Company-owned multiple tenant towers, the Company does from time to time provide network design and site selection services to carriers and other customers on a consulting contract basis. The Company's network design and site selection services provide customers with relevant information including recommendations regarding location and height of towers, appropriate types of antennas, transmission power and frequency selection and related fixed network considerations. Site Acquisition. In the United Kingdom, the Company is involved in site acquisition services for its own purposes and for third parties. The Company recognizes that the site acquisition phase often carries the highest risk for a project. To ensure the greatest possible likelihood of success and timely acquisition, the Company combines a desktop survey of potential barriers to development with a physical site search that includes initial design analyses, CDM assessments and, where necessary, line-of-sight surveys. The Company leverages off its experience in site acquisition and co-location when meeting with local planning authorities. Site Development and Antenna Installation. The Company uses a combination of external and internal resources for site construction. The Company's engineers are experienced in both construction techniques and construction management, ensuring an efficient and simple construction phase. Selected civil contractors are managed by CTI staff for the ground works phase. Specialist erection companies, with whom the Company has a long association, are used for tower installation. Final antenna installation is undertaken by the Company's own experienced teams. Site Management and Other Services. The Company also provides complete site management, preventive maintenance, fault repair and system management services to the Scottish Ambulance Service. It also maintains 103

a mobile radio system for the Greater Manchester Police and provides maintenance and repair services for transmission equipment and site infrastructure. Significant Contracts CTI's principal analog broadcast transmission contract is the BBC Analog Transmission Contract. CTI also has entered into two digital television transmission contracts, the BBC Digital Transmission Contract and the ONdigital Digital Transmission Contract (as defined). CTI also provides facilities to NTL (in its capacity as a broadcast transmission provider to non-CTI customers) under the Site-Sharing Agreement. The Company also has long-term service agreements with broadcast customers such as Virgin Radio and Talk Radio. In addition, CTI has several agreements with telecommunications providers, including leases, site management contracts and independent contractor agreements. The Company has entered into contracts to design and build communications equipment and related infrastructure for customers such as Cellnet, One2One, Orange, Scottish Telecom and Vodafone. BBC Analog Transmission Contract CTI entered into a 10-year transmission contract with the BBC for the provision of terrestrial analog television and analog and digital radio transmission services in the United Kingdom at the time the BBC Home Service Transmission Business was acquired, which contract was subsequently amended on July 16, 1998 (the "BBC Analog Transmission Contract") to incorporate a small number of minor modifications requested by the BBC. The BBC Analog Transmission Contract provides for charges of approximately (Pounds)46.5 million ($79.0 million) to be payable by the BBC to CTI for the year ended March 31, 1998 and each year thereafter to the termination date, adjusted annually at the inflation rate less 1%. In addition, for the duration of the contract an annual payment of (Pounds)300,000 ($509,850) is payable by the BBC for additional broadcast-related services. At the BBC's request, since October 1997, the number of television broadcast hours has been increased to 24 hours per day for the BBC's two national television services, which has added over (Pounds)500,000 ($849,750) annually to the payments made by the BBC to the Company. The BBC Analog Transmission Contract also provides for CTI to be liable to the BBC for "service credits" (i.e., rebates of its charges) in the event that certain standards of service are not attained as a result of what the contract characterizes as "Accountable Faults" or the failure to meet certain "response times" in relation to making repairs at certain key sites. The Company believes that CTI is well-equipped to meet the BBC's service requirements by reason of the collective experience its existing management gained while working with the BBC. Following completion of three formal six-month performance reviews, CTI achieved a 100% "clean sheet" performance, incurring no service credit penalties. The initial term of the BBC Analog Transmission Contract ends on March 31, 2007. Thereafter, the BBC Analog Transmission Contract may be terminated with 12 months' prior notice by either of the parties, expiring on March 31 in any contract year, from and including March 31, 2007. It may also be terminated earlier (i) by mutual agreement between CTI and the BBC, (ii) by one party upon the bankruptcy or insolvency of the other party within the meaning of section 123 of the Insolvency Act 1986, (iii) upon certain force majeure events with respect to the contract as a whole or with respect to any site (in which case the termination will relate to that site only), (iv) by the non- defaulting party upon a material breach by the other party and (v) upon the occurrence of certain change of control events (as defined in the BBC Analog Transmission Contract). BBC Commitment Agreement On February 28, 1997, in connection with the acquisition of the BBC Home Service Transmission Business, the Company, TdF, TeleDiffusion de France S.A., which is the parent company of TdF and DFI ("TdF Parent"), and the BBC entered into the BBC Commitment Agreement (the "BBC Commitment Agreement"), whereby the Company and TdF agreed (i) not to dispose of any shares in CTSH or any interest in such shares (or enter into any agreement to do so) until February 28, 2000; and (ii) to maintain various minimum indirect ownership 104

interests in CTI and CTSH for periods ranging from three to five years commencing February 28, 1997. These provisions restrict the ability of CCIC and TdF to sell, transfer or otherwise dispose of their respective CTSH shares (and, indirectly, their CTI shares). The restrictions do not apply to disposals of which the BBC has been notified in advance and to which the BBC has given its prior written consent, which, subject to certain exceptions, consent shall not be unreasonably withheld or delayed. The BBC has consented to waive the above restrictions (i) to enable the Company and TdF to enter into the Governance Agreement and the CTSH Shareholders' Agreement and (ii) to allow the exercise of rights under such agreements and (iii) to permit the roll-up of CTI immediately prior to the IPO. The BBC Commitment Agreement also required TdF Parent and the Company to enter into a services agreements with CTI. The original services agreement entered into by TdF Parent and CTI on February 28, 1997 (pursuant to which TdF makes available certain technical consultants, executives and engineers to CTI) was amended on August 21, 1998 to extend the original minimum term of services provided from three years to seven years, commencing February 28, 1997, thereafter terminable on 12-month's prior notice given by CTI to TdF after February 28, 2003. See "The Roll-Up--Roll-Up Arrangements--CTI Series Agreement". ONdigital Digital Transmission Contract In 1997, the Independent Television Commission awarded ONdigital three of the five available commercial digital terrestrial television multiplexes for new program services. The Company bid for and won the 12 year contract from ONdigital to build and operate its digital television transmission network (the "ONdigital Digital Transmission Contract"). The contract provides for approximately (Pounds)20.0 million ($34.0 million) of revenue per year from 2001 to 2008, with lesser amounts payable before and after these years and with service credits repayable for performance below agreed thresholds. BBC Digital Transmission Contract In 1998, the Company bid for and won the 12 year contract from the BBC to build and operate its digital terrestrial television transmission network (the "BBC Digital Transmission Contract"). This contract provides for approximately (Pounds)10.5 million ($17.8 million) of revenue per year (assuming the BBC commits to the full DTT roll-out contemplated by the BBC Digital Transmission Contract) during the 12 year period, with service credits repayable for performance below agreed thresholds. There is a termination provision during the three-month period following the fifth anniversary of the Company's commencement of digital terrestrial transmission services for the BBC exercisable by the BBC but only if the BBC's Board of Governors determines, in its sole discretion, that DTT in the United Kingdom does not have sufficient viewership to justify continued DTT broadcasts. Under this provision, the BBC will pay the Company a termination fee in cash that substantially recovers the Company's capital investment in the network, and any residual ongoing operating costs and liabilities. Like the BBC Analog Transmission Contract, the contract is terminable upon the occurrence of certain change of control events (as defined in the BBC Digital Transmission Contract). BT Digital Distribution Contract Under the BBC Digital Transmission Contract and the ONdigital Digital Transmission Contract, in addition to providing digital terrestrial transmission services, CTI has agreed to provide for the distribution of the BBC's and ONdigital's broadcast signals from their respective television studios to CTI's transmission network. Consequently, in May 1998, CTI entered into a 12 year distribution contract (the "BT Digital Distribution Contract") with British Telecommunications plc ("BT") (with provisions for extending the term), in which BT has agreed to provide fully duplicated, fiber-based, digital distribution services, with penalties for late delivery and service credits for failure to deliver 99.99% availability. Site-Sharing Agreement In order to optimize service coverage and enable viewers to receive all analog UHF television services using one receiving antenna, the BBC, as the predecessor to CTI, and NTL made arrangements to share all UHF 105

television sites. This arrangement was introduced in the 1960s when UHF television broadcasting began in the United Kingdom. In addition to service coverage advantages, the arrangement also minimizes costs and avoids the difficulties of obtaining additional sites. Under the Site-Sharing Agreement, the party that is the owner, lessee or licensee of each site is defined as the "Station Owner". The other party (the "Sharer") is entitled to request a license to use certain facilities at that site. The Site-Sharing Agreement and each site license provide for the Station Owner to be paid a commercial license fee in accordance with the Site-Sharing Agreement ratecard and for the Sharer to be responsible, in normal circumstances, for the costs of accommodation and equipment used exclusively by it. The Site-Sharing Agreement may be terminated with five years' prior notice by either of the parties and expires on December 31, 2005 or on any tenth anniversary of that date. It may also be terminated (i) following a material breach by either party which, if remediable, is not remedied within 30 days of notice of such breach by the non-breaching party, (ii) on the bankruptcy or insolvency of either party and (iii) if either party ceases to carry on a broadcast transmission business or function. Negotiations are in progress between the Company and NTL to amend the Site- Sharing Agreement to account for the build-out of digital transmission sites and equipment, a new rate card related to site sharing fees for new digital facilities and revised operating and maintenance procedures related to digital equipment. Vodafone On April 16, 1998, under Vodafone's master lease agreement with the Company, Vodafone agreed to locate antennas on 122 of the Company's existing communication sites in the United Kingdom. The first 35 sites had been completed by the end of November 1998. This included 4 sites at which a new tower had been constructed to replace an existing structure of limited capacity. The remaining sites are expected to be completed by end of July 1999 and will include the construction of a further 60 replacement towers. After their upgrade, these sites will be able to accommodate additional tenants. Customers For the nine months ended September 30, 1998, the BBC accounted for approximately 59% of CTI's revenues. This percentage has decreased from 63% in 1997 and is expected to continue to decline as CTI continues to expand its site rental business and as DTT begins to be transmitted. CTI provides all four U.K. PCN/cellular operators (Cellnet, One2One, Orange and Vodafone) with infrastructure services and also provides fixed telecommunications operators, such as BT, Cable & Wireless Communications, Energis and Scottish Telecom, with microwave links and backhaul infrastructure. The following is a list of some of CTI's leading site rental customers by industry segment. Industry Selected Customers -------- ------------------ Paging Page One, Hutchinson Public Telecommunications BT, Cable & Wireless Communications PCN Orange, One2One Cellular Cellnet, Vodafone PMR/TETRA National Band 3, Dolphin Governmental Agencies Ministry of Defense Broadcasting XFM, BBC, NTL Data RAM Mobile Data, Cognito Other Aerial Sites, Health Authorities Utilities Welsh Water, Southern Electric Sales and Marketing The Company has 22 sales and marketing personnel in the United Kingdom who identify new revenue-generating opportunities, develop and maintain key account relationships, and tailor service offering to meet the 106

needs of specific customers. An excellent relationship has been maintained with the BBC, and successful new relationships have been developed with many of the major broadcast and wireless communications carriers in the United Kingdom. The Company has begun to actively cross-sell its products and services so that, for example, site rental customers are also offered build- to-suit services. Competition NTL, the privatized engineering division of the IBA and now a subsidiary of NTL Inc. (formerly International CableTel Inc.), is CTI's primary competition in the terrestrial broadcast transmission market in the United Kingdom. NTL provides analog transmission services to ITV, Channels 4 and 5, and S4C. It also has been awarded the transmission contract for the new DTT multiplex service from Digital 3 & 4 Limited, and a similar contract for the DTT service for SDN (CTI has been awarded similar contracts for the BBC and ONdigital-- serving a total of four multiplexes compared with NTL's two). Since its creation in 1991, NTL has diversified from its core television broadcasting business using its transmission infrastructure to enter into the radio transmission and telecommunications sectors. Although CTI and NTL are direct competitors, they have reciprocal rights to the use of each others' sites for broadcast transmission usage in order to enable each of them to achieve the necessary country-wide coverage. This relationship is formalized by the Site-Sharing Agreement entered into in 1991, the time at which NTL was privatized. NTL also offers site rental on approximately 1,000 of its sites (some of which are managed on behalf of third parties). Like CTI, NTL offers a full range of site-related services to its customers, including installation and maintenance. CTI believes its towers to be at least as well situated as NTL's and that it will be able to expand its own third-party site-sharing penetration. CTI also believes that its penetration of this market has to date lagged behind NTL only because of the governmental restrictions on the commercial activities of CTI's business prior to its privatization. All four U.K. mobile operators own site infrastructure and lease space to other users. Their openness to sharing with direct competitors varies by operator. Cellnet and Vodafone have agreed to cut site costs by jointly developing and acquiring sites in the Scottish Highlands. BT and Cable & Wireless Communications are both major site sharing customers but also compete by leasing their own sites to third parties. BT's position in the market is even larger when considered in combination with its interest in Cellnet. Several other companies compete in the market for site rental. These include British Gas, Racal Network Systems, Aerial Sites Plc, Simoco, Relcom Aerial Services and the Royal Automobile Club. Some companies own sites initially developed for their own networks, while others are developing sites specifically to exploit this market. CTI faces competition from a large number of companies in the provision of network services. The companies include NTL, specialty consultants and equipment manufacturers such as Nortel and Ericsson. Properties In the United States, the Company's interests in its tower sites are comprised of a variety of fee interests, leasehold interests created by long- term lease agreements, private easements and easements, licenses or rights-of- way granted by government entities. In rural areas, a tower site typically consists of a three- to five-acre tract, which supports towers, equipment shelters and guy wires to stabilize the structure. Less than 3,000 square feet are required for a self-supporting tower structure of the kind typically used in metropolitan areas. The Company's land leases generally have five- or ten- year terms and frequently contain one or more renewal options. Some land leases provide "trade-out" arrangements whereby the Company allows the landlord to use tower space in lieu of paying all or part of the land rent. As of September 30, 1998, the Company had approximately 384 land leases. Pursuant to the Senior Credit Facility, the Company's senior lenders have liens on a substantial number of the Company's land leases and other property interests in the United States. 107

In the United Kingdom, tower sites range from less than 400 square feet for a small rural TV booster station to over 50 acres for a high-power radio station. As in the United States, the site accommodates the towers, equipment buildings or cabins and, where necessary, guy wires to support the structure. Land is either owned freehold, which is usual for the larger sites, or is held on long-term leases that generally have terms of 21 years or more. Legal Proceedings The Company is occasionally involved in legal proceedings that arise in the ordinary course of business. Most of these proceedings are appeals by landowners of zoning and variance approvals of local zoning boards. While the outcome of these proceedings cannot be predicted with certainty, management does not expect any pending matters to have a material adverse effect on the Company's financial condition or results of operations. Employees At December 1, 1998, the Company employed 883 people worldwide. Other than in the United Kingdom, the Company is not a party to any collective bargaining agreements. In the United Kingdom, the Company is party to a collective bargaining agreement with the Broadcast, Entertainment, Cinematographic and Technicians Union. This agreement establishes bargaining procedures relating to the terms and conditions of employment for all of CTI's non-management staff. The Company has not experienced any strikes or work stoppages, and management believes that the Company's employee relations are good. Regulatory Matters United States Federal Regulations. Both the FCC and FAA regulate towers used for wireless communications transmitters and receivers. Such regulations control the siting and marking of towers and may, depending on the characteristics of particular towers, require registration of tower facilities. Wireless communications devices operating on towers are separately regulated and independently licensed based upon the particular frequency used. The FCC, in conjunction with the FAA, has developed standards to consider proposals for new or modified antenna structures. These standards mandate that the FCC and the FAA consider the height of proposed antenna structures, the relationship of the structure to existing natural or man-made obstructions and the proximity of the antenna structures to runways and airports. Proposals to construct or to modify existing antenna structures above certain heights are reviewed by the FAA to ensure the structure will not present a hazard to aviation. The FAA may condition its issuance of a no-hazard determination upon compliance with specified lighting and/or marking requirements. The FCC will not license the operation of wireless telecommunications devices on towers unless the tower has been registered with the FCC or a determination has been made that such registration is not necessary. The FCC will not register a tower unless it has been cleared by the FAA. The FCC may also enforce special lighting and painting requirements. Owners of wireless transmissions towers may have an obligation to maintain painting and lighting to conform to FCC standards. Tower owners may also bear the responsibility of notifying the FAA of any tower lighting outage. The Company generally indemnifies its customers against any failure to comply with applicable regulatory standards. Failure to comply with the applicable requirements may lead to civil penalties. The 1996 Telecom Act preempted certain state and local zoning authorities' jurisdiction over the construction, modification and placement of towers. The new law prohibits any action that would (i) discriminate between different providers of personal wireless services or (ii) ban altogether the construction, modification or placement of radio communications towers. Finally, the 1996 Telecom Act requires the federal government to help licensees for wireless communications services gain access to preferred sites for their facilities. This may 108

require that federal agencies and departments work directly with licensees to make federal property available for tower facilities. Local Regulations. Local regulations include city and other local ordinances, zoning restrictions and restrictive covenants imposed by community developers. These regulations vary greatly, but typically require tower owners to obtain approval from local officials or community standards organizations prior to tower construction. Local zoning authorities generally have been hostile to construction of new transmission towers in their communities because of the height and visibility of the towers. Licenses Under the Communications Act of 1934. The Company, through certain of its subsidiaries, holds licenses for radio transmission facilities granted by the FCC, including licenses for common carrier microwave and paging services and commercial mobile radio services ("CMRS"), which are subject to additional regulation by the FCC. The Company is required to obtain the FCC's approval prior to the transfer of control of any of its FCC licenses. Consummation of the IPO and the Roll-Up would have resulted in a transfer of control of the Company under the FCC's rules and policies if, after such transactions, over 50% of the voting stock of the Company would have been owned by new stockholders. As a precautionary measure, the Company applied to the FCC for consent to transfer of control of the Company to the post-Roll-Up and IPO stockholders to the extent such transactions would have required prior FCC approval. The Company, as the parent company of the licensees of common carrier and CMRS facilities, is also subject to Section 310(b)(4) of the Communications Act of 1934, as amended, which would limit the Company to a maximum of 25% foreign ownership absent a ruling from the FCC that foreign ownership in excess of 25% is in the public interest. In light of the World Trade Organization Agreement on Basic Telecommunications Services ("WTO Agreement"), which took effect on February 5, 1998, the FCC has determined that such investments are generally in the public interest if made by individuals and entities from WTO-member nations. The Company is over 25% foreign owned by companies headquartered in France, the United Kingdom and New Zealand. See "Principal and Selling Stockholders". Each of these nations is a signatory to the WTO Agreement. The FCC has granted approval of up to 49.9% foreign ownership of the Company, at least 25% of which will be from WTO-member nations. United Kingdom Telecommunications systems and equipment used for the transmission of signals over radio frequencies have to be licensed in the United Kingdom. These licenses are issued on behalf of the British Government by the Secretary of State for Trade and Industry under the Telecommunications Act 1984 and the Wireless Telegraphy Acts 1949, 1968 and 1998. CTI has a number of such licenses under which it runs the telecommunications distribution and transmission systems which are necessary for the provision of its transmission services. CTI's operations are subject to comprehensive regulation under the laws of the United Kingdom. Licenses under the Telecommunications Act 1984 CTI has the following three licenses under the Telecommunications Act 1984: Transmission License. The Transmission License is a renewable license to run telecommunications systems for the transmission via wireless telegraphy of broadcasting services. This license is for a period of at least twenty-five years from January 23, 1997, and is CTI's principal license. Its main provisions include: (i) a price control condition covering the provision of all analog radio and television transmission services to the BBC under the BBC Analog Transmission Agreement (for an initial price of approximately (Pounds)44 million for regulated elements of the services provided by CTI under the BBC Analog Transmission Agreement in the year ended March 31, 1997, subject to an increase cap which is 1% below the rate of increase in the Retail Price Index over the previous calendar year). The current price control condition applies until March 31, 2006; 109

(ii) a change of control provision which requires notification of acquisitions of interest in CTI of more than 20% by a public telecommunications operator or any Channel 3 or Channel 5 licensee, which acquisitions entitle the Secretary of State to revoke the license; (iii) a site sharing requirement requiring CTI to provide space on its towers to analog and digital broadcast transmission operators and including a power for the Director General of Telecommunications ("OFTEL"), as the regulator, to determine prices if there is failure between the site owner and the prospective site sharer to agree to a price; (iv) a fair trading provision enabling OFTEL to act against anti- competitive behavior by the licensee; and (v) a prohibition on undue preference or discrimination in the provision of the services it is required to provide third parties under the Transmission License. OFTEL has made a determination with respect to a complaint made by Classic FM and NTL in respect of certain charges, imposed previously by the BBC under the Site-Sharing Agreement with NTL for the use by Classic FM of BBC radio antennas and passed on to Classic FM by NTL. OFTEL's position is that the Site-Sharing Agreement did not cover charges for new services to customers such as Classic FM, thereby enabling OFTEL to intervene and determine the appropriate rate under the "Applicable Rate" mechanism in CTI's Transmission License. This procedure could result in an amendment to the Site-Sharing Agreement and could in turn lead to a diminution of CTI's income of approximately (Pounds)300,000 per annum (equivalent to approximately 0.4% of revenues and 1.0% of EBITDA for the fiscal year ended March 31, 1997). CTI has applied for leave to obtain a judicial review of this decision. In addition, CTI has made a provision of approximately (Pounds)1.9 million relating to any rate adjustment imposed by OFTEL with respect to previous charges for Classic FM under the Site-Sharing Agreement. CTI is discussing with OFTEL certain amendments to CTI's Telecommunications Act Transmission License to ensure that the price control condition accommodates the provision by CTI of additional contractually agreed upon services to the BBC in return for additional agreed upon payments. See "Risk Factors--Regulatory Compliance and Approval". The Secretary of State has designated the Transmission License a public telecommunications operator ("PTO") license in order to reserve to himself certain emergency powers for the protection of national security. The PTO designation is, however, limited to this objective. CTI does not have a full domestic PTO license and does not require one for its current activities. The Department of Trade and Industry has, nevertheless, indicated that it would be willing to issue CTI such a license. As a result CTI would gain wider powers to provide services to third parties including public switched voice telephony and satellite uplink and would grant CTI powers to build out its network over public property (so-called "code powers"). General Telecom License. The General Telecom License is a general license to run telecommunications systems and authorizes CTI to run all the necessary telecommunications systems to convey messages to its transmitter sites (e.g., via leased circuits or using its own microwave links). The license does not cover the provision of public switched telephony networks (which would require a PTO license as described above). Satellite License. The Satellite License is a license to run telecommunications systems for the provision of satellite telecommunication services and allows the conveyance via satellite of messages, including data and radio broadcasting. The license excludes television broadcasting direct to the home via satellite although distribution via satellite of television broadcasting services which are to be transmitted terrestrially is permitted. Licenses under the Wireless Telegraphy Acts 1949, 1968 and 1998 CTI has three licenses under the Wireless Telegraphy Acts 1949, 1968 and 1998, authorizing the use of radio equipment for the provision of certain services over allocated radio frequencies: 110

(i) a Broadcasting Services License in relation to the transmission services provided to the BBC, Virgin Radio and Talk Radio; (ii) a Fixed Point-to-Point Radio Links License; (iii) two DAB Test and Development Licenses; and (iv) a DTT Test & Development License. All the existing licenses under the Wireless Telegraphy Acts 1949, 1968 and 1998 have to be renewed annually with the payment of a significant fee. The BBC, Virgin Radio and Talk Radio have each contracted to pay their portion of these fees. ONdigital is obligated under the Ondigital Digital Transmission Contract to pay most of these fees. Environmental Matters The Company's operations are subject to foreign, federal, state and local laws and regulations relating to the management, use, storage, disposal, emission, and remediation of, and exposure to, hazardous and nonhazardous substances, materials and wastes ("Environmental Laws"). As an owner and operator of real property, the Company is subject to certain Environmental Laws that impose strict, joint and several liability for the cleanup of on- site or off-site contamination relating to existing or historical operations, and also could be subject to personal injury or property damage claims relating to such contamination. The Company is potentially subject to cleanup liabilities in both the United States and the United Kingdom. The Company also is subject to regulations and guidelines that impose a variety of operational requirements relating to RF emissions. The potential connection between RF emissions and certain negative health effects, including some forms of cancer, has been the subject of substantial study by the scientific community in recent years. To date, the results of these studies have been inconclusive. Although the Company has not been subject to any claims relating to RF emissions, it has established operating procedures designed to reduce employee exposures to RF emissions and is presently evaluating certain of its towers and transmission equipment in the United States and the United Kingdom to determine whether RF emission reductions are possible. In addition, the Company is subject to licensing, registration and related requirements concerning tower siting, construction and operation. In the United States, the FCC's decision to license a proposed tower may be subject to environmental review pursuant to the National Environmental Policy Act of 1969 ("NEPA"), which requires federal agencies to evaluate the environmental impacts of their decisions under certain circumstances. The FCC regulations implementing NEPA place responsibility on each applicant to investigate any potential environmental effects of a proposed operation and to disclose any significant effects on the environment in an environmental assessment prior to commencing construction. In the event the FCC determines that a proposed tower would have a significant environmental impact, the FCC would be required to prepare an environmental impact statement. This process could significantly delay or prevent the registration or construction of a particular tower, or make tower construction more costly. In certain jurisdictions, local laws or regulations may impose similar requirements. The Company believes that it is in substantial compliance with all applicable Environmental Laws. Nevertheless, there can be no assurance that the costs of compliance with existing or future Environmental Laws will not have a material adverse effect on the Company's business, results of operations, or financial condition. 111

At the end of such two-year period, the Company will pay Mr. Crown a severance benefit of $300,000. The Company also agreed to vest all of Mr. Crown's existing stock options; to immediately grant Mr. Crown options to purchase 50,000 shares of Common Stock at $7.50 per share; and, upon the closing of the IPO, to grant Mr. Crown options to purchase 625,000 shares of Common Stock at the price to public in the IPO. Stock Option Plans 1995 Stock Option Plan The Company has adopted the 1995 Stock Option Plan, which was reamended on July 1, 1998 (the "1995 Stock Option Plan"). The purpose of the 1995 Stock Option Plan is to advance the interests of the Company by providing additional incentives and motivations which help the Company to attract, retain and motivate employees, directors and consultants. The description set forth below summarizes the general terms of the 1995 Stock Option Plan and the options granted pursuant to the 1995 Stock Option Plan. Pursuant to the 1995 Stock Option Plan, the Company can grant options to purchase up to 18,000,000 shares of Common Stock. Options granted under the 1995 Stock Option Plan may either be incentive stock options ("ISOs") under Section 422 of the Code or nonqualified stock options. The price at which a share of Common Stock may be purchased upon exercise of an option granted under the 1995 Stock Option Plan will be determined by the Board of Directors and, in the case of nonqualified stock options, may be less than the fair market value of the Common Stock on the date that the option is granted. The exercise price may be paid in cash, in shares of Common Stock (valued at fair market value at the date of exercise), in option rights (valued at the excess of the fair market value of the Common Stock at the date of exercise over the exercise price) or by a combination of such means of payment, as may be determined by the Board. Employees, directors or consultants of the Company (including its subsidiaries and affiliates) are eligible to receive options under the 1995 Stock Option Plan (although only certain employees are eligible to receive ISOs). The 1995 Stock Option Plan is administered by the Board and the Board is authorized to interpret and construe the 1995 Stock Option Plan. Subject to the terms of the 1995 Stock Option Plan, the Board is authorized to select the recipients of options from among those eligible, to establish the number of shares that may be issued under each option and to take any actions specifically contemplated or necessary or advisable for the administration of the 1995 Stock Option Plan. No options may be granted under the 1995 Stock Option Plan after July 31, 2005, which is ten years from the date the 1995 Stock Option Plan was originally adopted and approved by the Board and stockholders of the Company. The 1995 Stock Option Plan will remain in effect until all options granted under the 1995 Stock Option Plan have been exercised or expired. The Board, in its discretion, may terminate the 1995 Stock Option Plan at any time with respect to any shares of Common Stock for which options have not been granted. The 1995 Stock Option Plan may be amended by the Board without the consent of the stockholders of the Company, other than as to a material increase in benefits, an increase in the number of shares that may be subject to options under the 1995 Stock Option Plan or a change in the class of individuals eligible to receive options under the 1995 Stock Option Plan. However, no change in any option previously granted under the 1995 Stock Option Plan may be made which would impair the rights of the holder of such option without the approval of the holder. Pursuant to the 1995 Stock Option Plan, options are exercisable during the period specified in each option agreement or certificate; provided, however, that no option is exercisable later than ten years from the date the option is granted. Options generally have been exercisable over a period of ten years from the grant date and vested in equal installments over a four or five year period of service with the Company as an employee. A change in control generally accelerates the vesting of options granted to employees and some of the options vest 118

upon the achievement of specific business goals or objectives. An option generally must be exercised within 12 months of a holder ceasing to be involved with the Company as an employee, director or consultant as a result of death and within three months if the cessation is for other reasons; however, these periods can be extended by decision of the Board (other than in the case of an ISO). Shares of Common Stock subject to forfeited or terminated options again become available for option awards. The Board may, subject to certain restrictions in the 1995 Stock Option Plan (and, in the case of an ISO, in Section 422 of the Code), extend or accelerate the vesting or exercisability of an option or waive restrictions in an option agreement or certificate. The 1995 Stock Option Plan provides that the total number of shares covered by the 1995 Stock Option Plan, the number of shares covered by each option, and the exercise price per share under each option will be proportionately adjusted in the event of a recapitalization, stock split, dividend, or a similar transaction. No grant of any option will constitute realized taxable income to the grantee. Upon exercise of a nonqualified option, the holder will recognize ordinary income in an amount equal to the excess of the fair market value of the stock received over the exercise price paid therefor and the tax basis in any shares of Common Stock received pursuant to the exercise of such option will be equal to the fair market value of the shares on the exercise date if the exercise price is paid in cash. The Company will generally have a deduction in parity with the amount realized by the holder. The Company has the right to deduct and withhold applicable taxes relating to taxable income realized by the holder upon exercise of a nonqualified option and may withhold cash, shares or any combination in order to satisfy or secure its withholding tax obligation. An ISO is not subject to taxation as income to the employee at the date of grant or exercise and the Company does not get a business deduction as to an ISO; provided, the stock is not sold within two years after the ISO was granted and one year after the ISO was exercised. The ISO is effectively taxed at capital gain rates upon the sale of the stock by the employee. However, if the stock acquired upon exercise of an ISO is sold within two years of the ISO grant date or one year exercise of the date, then it is taxed the same as a Nonqualified Option. Upon the exercise of an ISO, the difference between the value of the stock and the exercise price is recognized as a preference item for alternative minimum tax purposes. As of December 31, 1998, options to purchase a total of 13,082,220 shares of Common Stock have been granted. Options for 572,825 shares of Common Stock have been exercised, options for 278,250 shares have been forfeited and options for 12,231,145 shares remain outstanding. The outstanding options are for (i) 345,000 shares with an exercise price of $0.40 per share, (ii) 43,750 shares with an exercise price of $1.20 per share, (iii) 50,000 shares with an exercise price of $1.60 per share, (iv) 175,000 shares with an exercise price of $2.40 per share, (v) 5,385 shares with an exercise price of $3.09 per share, (vi) 5,385 shares with an exercise price of $4.03 per share, (vii) 1,630,625 shares with an exercise price of $4.20 per share, (viii) 23,135 shares with an exercise price of $4.76 per share, (ix) 5,385 shares with an exercise price of $5.24 per share, (x) 28,000 shares with an exercise price of $5.97 per share; (xi) 107,200 shares with an exercise price of $6.00 per share, (xii) 5,085,530 shares with an exercise price of $7.50 per share, (xiii) 28,000 shares with an exercise price of $7.77 per share, (xiv) 28,000 shares with an exercise price of $10.08 per share, (xv) 75,000 shares with an exercise price of $11.31 per share, (xvi) 75,000 shares with an exercise price of $11.50 per share, (xvii) 125,000 shares with an exercise price of $11.98 per share, (xviii) 253,750 shares with an exercise price of $12.50 per share and (xix) 4,136,500 shares with an exercise price of $13.00 per share. The options exercisable at $0.40 per share are fully vested and held by Ted B. Miller, Jr. Vested and exercisable options also include options for (i) 43,750 shares at $1.20 per share, (ii) 50,000 shares at $1.60 per share, (iii) 175,000 shares at $2.40 per share, (iv) 1,463,625 shares at $4.20 per share, (v) 23,135 shares at $4.76 per share, (vi) 107,200 shares at $6.00 per share, (vii) 2,805,630 shares at $7.50 per share, (viii) 128,750 shares at $12.50 per share and (ix) 90,000 shares at $13.00 per share. Except for the options for 23,135 shares with an exercise price of $4.76 per share and options for 3,036,250 shares with an exercise price of $7.50, the exercise prices for all of the options were equal to or in excess of the estimated fair value of the Common Stock at the dates on which the numbers of shares and the exercise prices were determined; as such, in accordance with the "intrinsic value based method" of accounting for stock options, the Company did not recognize compensation cost related to the grant of these options. The options for 23,135 shares with an exercise price of $4.76 were issued in 1998 in exchange for services received from nonemployees; as such, the Company will account for the issuance of these options in 1998 based on the 119

fair value of the services received. Options for 3,036,250 shares granted at an exercise price of $7.50 per share (which is below the estimated fair market value at the date of grant) were included in the group of options which vested at the consummation of the initial public offering of common stock. The Company will account for these options in 1998 based upon the fair market value of services received. The remaining options for 2,731,230 shares granted at an exercise price of $7.50 per share (which is below the estimated fair market value at the date of grant) were granted in 1998 and generally are taken into account and vest over five years. See "Management's Discussion and Analysis of Financial Condition and Results of Operations--Compensation Charges Related to Stock Option Grants". Since January 1, 1998, the Company has granted to its executive officers and directors options for a total of 2,515,500 shares at an exercise price of $7.50, 250,000 shares at an exercise price of $12.50 and 3,235,000 shares at an exercise price of $13.00 under the 1995 Stock Option Plan.

CTSH Stock Option Plans CTSH has established certain stock option plans for the benefit of its employees (the "CTSH Stock Option Plans"). Upon consummation of the Roll-Up in August 1998, all of the outstanding options to purchase shares of capital stock of CTSH ("CTSH Options") granted pursuant to the CTSH Stock Option Plans were converted into and replaced by options to purchase shares of the Company's Common Stock ("CCIC Options"). The Company's Board of Directors has adopted each of the CTSH Option Plans. Options granted under the CTSH Stock Options Plans may be adjusted at the discretion of the Company or, in the case of options granted under the CTSH Share Bonus Plan (as defined), the CTSH Trustee (as defined) to take into account any variation of the share capital of the Company subject to the written confirmation of the auditors of the Company that the adjustment in their opinion is fair and reasonable. The description set forth below summarizes the general terms of each of the various plans that constitute the CTSH Stock Options Plans. Included in CTI's operating expenses for the nine months ended September 30, 1998 are noncash compensation charges for (Pounds)2.5 million ($4.3 million) related to the issuance of stock options to certain executives and employees. CTSH All Employee Share Option Scheme. All outstanding options granted pursuant to the Castle Transmission Services (Holdings) Ltd. All Employee Share Option Scheme (the "CTSH All Employee Plan") are vested. These options may only be exercised in full and on one occasion. Outstanding options granted pursuant to the CTSH All Employee Plan will lapse if not exercised by the earlier of (i) the first anniversary of the option holder's death, (ii) six months following the termination of the option holder's employment with the Company, (iii) six months following the earlier of (a) a change of control of the Company, (b) the sanctioning by the U.K. courts of a compromise or arrangement pursuant to U.K. Companies Act 1985 section 425 that affects the Common Stock of the Company, (c) a person becoming bound or entitled to acquire the Common Stock of the Company under U.K. Companies Act 1985 sections 428-430 or (d) notice of a general meeting of the stockholders of the Company at which a resolution will be proposed for the purpose of a voluntary winding- up of the Company (each of the foregoing, a "Corporate Event"), (iv) the option holder being adjudicated bankrupt under U.K. law, (v) the surrender of the option or (vi) the seventh anniversary of the grant. At the time of the Roll-up there were outstanding options to purchase 285,250 shares of Common Stock at a price of $2.37 per share, of which an initial refundable deposit of $1.20 per share has already been paid by each participant. No additional options will be granted under the CTSH All Employee Plan in the future. 120

CTSH Management Plan. All outstanding options granted pursuant to the Castle Transmission Services (Holdings) Ltd. Unapproved Share Option Scheme (the "CTSH Management Plan") will vest on the earlier of (i) March 1, 2000 or, if the option holder was not an Eligible Employee (as defined in the CTSH Management Plan) on March 1, 1997, the third anniversary of the date on which the option was granted, (ii) the death of the option holder, (iii) the termination of the option holder's employment with the Company (other than a termination for cause, or the voluntary resignation of the option holder), (iv) a Corporate Event or (v) the sale of the subsidiary or business of the Company in which the option holder is employed. Once vested, these options may be exercised in whole or in part at the discretion of the option holder prior to the lapsing of the option. All options granted pursuant to the CTSH Management Plan will lapse on the earlier of (i) the first anniversary of the option holder's death, (ii) six months after the termination of the option holder's employment with the Company (other than a termination for cause, or the voluntary resignation of the option holder), (iii) immediately upon any other termination of employment, (iv) six months following a Corporate Event, (v) the option holder being adjudicated bankrupt under U.K. law, (vi) the surrender of the option, (vii) failure to satisfy any performance condition established by the board of directors of CTI or (viii) the seventh anniversary of the grant of the option. Currently, there are outstanding options to purchase 1,649,844 shares of Common Stock at prices ranging from (Pounds)1.43 ($2.39) to (Pounds)6.04 ($10.08) per share. No additional options will be granted under the CTSH Management Plan in the future. CTSH Bonus Share Plan. In connection with the Castle Transmission Services (Holdings) Ltd. Bonus Share Plan (the "CTSH Bonus Share Plan"), CTSH has executed the Employee Benefit Trust (the "CTSH Trust"), a discretionary settlement for the benefit of past and present CTI employees, directors and their families. CTI employees and directors are able to participate in the CTSH Bonus Share Plan by foregoing a portion of their annual bonuses awarded by the Company in consideration for options to purchase shares of the Company's Common Stock held by the CTSH Trust at predetermined prices per share depending upon the year in which the investment is made. The predetermined price for 1997 investment was (Pounds)13.00 ($21.70) per unit (each of which will be converted into seven shares of Common Stock upon consummation of the Roll-Up), and the CTI board has determined that the predetermined price for any investment in 1998 and 1999 will be (Pounds)16.90 ($28.21) and (Pounds)21.97 ($36.68) respectively. All outstanding options granted pursuant to the CTSH Bonus Share Plan are vested and may be exercised in whole or in part at the discretion of the option holder prior to the lapsing of the option. All options will lapse on the earlier of (i) the first anniversary of the option holder's death, (ii) six months after the termination of the option holder's employment with the Company, (iii) six months following a Corporate Event, (iv) the option holder being adjudicated bankrupt under U.K. law, (v) the surrender of the option or (vi) the seventh anniversary of the grant of the option. In order to satisfy the demand created by the exercise of options granted pursuant to the CTSH Bonus Share Plan, the CTSH Trustee has been granted a call option by the Company ("the U.K. Option Agreement") to purchase up to 149,709 shares of Common Stock from the Company at a price of (Pounds)1.86 ($3.11) per share, the funds for which are to be contributed to the CTSH Trust by CTSH (which has already provided for such payment in its financial statements). Currently there are outstanding options to purchase 149,709 shares of Common Stock from the CTSH Trustee for a nominal sum upon exercise. Following the Offering, CTI employees and directors will continue to be able to effectively invest a proportion of their annual bonuses in Common Stock of the Company under the CTSH Bonus Share Plan for the fiscal years 1998 and 1999. Thereafter, no additional options will be granted under the CTSH Share Bonus Plan. Grants under the CTSH Bonus Share Plan are determined by converting monetary awards into options to purchase shares at predetermined prices. CTSH Option Grants to Certain Executives. In January and April of 1998, CTSH granted options to purchase a total of 300,000 ordinary shares and 299,700,000 preference shares of CTSH to Ted B. Miller, Jr., David L. Ivy and George E. Reese. Upon consummation of the IPO, these options vested in full and converted into options to purchase 1,890,000 shares of the Company's Common Stock at an exercise price of (Pounds)1.43 ($2.39) and 210,000 shares of the Company's Common Stock at an exercise price of (Pounds)3.57 ($5.96). In addition, the exercise prices of such options will be set in U.S. dollars, converted from pounds sterling at the Noon Buying Rate on the date of the consummation of the Offering. 121

Standstill; Transfer Restrictions; Voting TdF and its affiliates will not, without the prior written consent of the Board; (1) acquire beneficial ownership of any voting securities of the Company if their ownership interest would be greater than the Relevant Percentage; (2) propose that TdF or any of its affiliates enter into any business combination involving the Company; (3) make any "solicitation" of "proxies" (as such terms are used in Regulation 14A promulgated under the Exchange Act) to vote or consent with respect to any voting securities of the Company in opposition to the recommendation of a super majority vote of the Board; (4) except in accordance with the terms of the Stockholders Agreement, seek election to or seek to place a representative on the Board or seek the removal of any member of the Board; (5) (A) solicit, seek to effect, negotiate with or provide nonpublic information to any other person with respect to or (B) otherwise make any public announcement or proposal with respect to, any form of business combination (with any person) involving a change of control of the Company or the acquisition of a substantial portion of the voting securities and/or equity securities or assets of the Company or any subsidiary of the Company; or (6) publicly disclose any intention, plan or arrangement, or provide advice or assistance to any person, inconsistent with the foregoing.

On August 21, 2000, unless the weighted average price per share of Common Stock over the five trading days immediately preceding August 21, 2000, is less than or equal to $12 (as adjusted for any stock split or similar transaction), the Company will have the right to require TdF to transfer and deliver to the Company all (except for one CTSH Ordinary Share) of the TdF CTSH Shares and the TdF CTSH Warrants beneficially owned by TdF and its affiliates in exchange for a number of shares of Class A Common Stock at the Exchange Ratio and 100,000 shares of Class A Common Stock, subject to adjustment in certain circumstances. Stockholders Agreement On August 21, 1998, the Company entered into the Stockholders Agreement (the "Stockholders Agreement") with certain stockholders of the Company (the "Stockholders") to provide for the certain rights and obligations of the Company and the Stockholders with respect to the governance of the Company and the Stockholders' shares of Common Stock or Class A Common Stock, as the case may be. Governance Board Representation.

(the "Centennial Group") is at least 5.0%, the Centennial Group will have the right to elect one director (the "Centennial Designee"); (vi) so long as the ownership interest of the Berkshire Group is at least 5.0%, the Berkshire Group will have the right to elect one director (the "Berkshire Designee"); (vii) so long as the ownership interest of Nassau Capital Partners II, L.P., NAS Partners I, L.L.C., their affiliates and their respective partners (the "Nassau Group") is not less than the ownership interest of the Nassau Group immediately following the closing of the IPO, the Nassau Group will have the right to elect one director (the "Nassau Designee"); and (viii) all directors other than the Designees ("General Directors") will be nominated in accordance with the Certificate of Incorporation and By-laws. Solicitation and Voting of Shares. With respect to each meeting of stockholders of the Company at which directors are to be elected, the Company will use its best efforts to solicit from the stockholders of the Company eligible to vote in the election of directors proxies in favor of the nominees selected in accordance with the provisions of the Stockholders Agreement (including without limitation the inclusion of each director nominee in management's slate of nominees and in the proxy statement prepared by management of the Company in respect of each annual meeting, vote or action by written consent).

Subject to certain exceptions, if at any time Stockholders holding at least 2% of the voting securities of the Company (the "Initiating Stockholder(s)") determine to sell or transfer 2% or more of the voting securities then issuable or outstanding to a third party who is not an affiliate of any of the Initiating Stockholders, Stockholders may have the opportunity and the right to sell to the purchasers in such proposed transfer (upon the same terms and conditions as the Initiating Stockholders) up to that number of Shares owned by such Stockholder equaling the product of (i) a fraction, the numerator of which is the number of Shares owned by such Stockholder as of the date of such proposed transfer and the denominator of which is the aggregate number of Shares owned by the Initiating Stockholders and by all Stockholders exercising tag-along rights multiplied by (ii) the number of securities to be offered. CTSH Shareholders' Agreement On August 21, 1998, CCIC, TdF and CTSH entered into a Shareholders' Agreement to govern the relationship between CCIC and TdF as Shareholders of CTSH (the "CTSH Shareholders' Agreement). Corporate Governance. The Board of CTSH will be comprised of six directors, of which CCIC and TdF will each have the right to appoint and remove two directors with the remaining two directors to be mutually agreed upon by CCIC and TdF. CCIC has the right to nominate the chairman, chief executive officer, chief operating officer and chief financial officer of CTSH, subject to approval buy a super majority vote of the Board of CCIC. The affirmative vote of a majority of the Board, including a director nominated by CCIC and a director nominated by TdF, is necessary for the adoption of a resolution. Further, the prior written consent of each of CCIC and TdF, in their capacities as shareholders, is required for the following actions, among others, significant acquisitions and dispositions; issuance of new shares; entry into transactions with shareholders, except pursuant 128

to the CTI Services Agreement and/or the CTI Operating Agreement; entry into new lines of business; capital expenditures outside the budget; entry into banking and other financing facilities; entry into joint venture arrangements; payment of dividends, except for (1) dividends payable in respect of CTSH's redeemable preferred shares and (2) dividends permitted by CTSH's financing facilities; and establishing a public market for CTSH shares. Similar governance arrangements also apply to CTSH's subsidiaries. If either CCIC or TdF vetoes a transaction (either at Board or shareholder level), the other shareholder is entitled to pursue that transaction in its own right and for its own account. Transfer Provisions. Subject to certain exceptions, neither CCIC nor TdF may transfer any interest in shares held in CTSH to a third party. Transfers of shares to affiliated companies are permitted, subject to certain conditions. No shares may be transferred if such transfer would (a) entitle the BBC to terminate either of the BBC contracts, (b) subject CTSH to possible revocation of its licenses under the Telecommunications Act 1984 or the Wireless Telegraphy Acts 1949, 1968 and 1998 or (c) cause CCIC or TdF to be in breach of the Commitment Agreement between the Company, TdF, TdF Parent and the BBC (under which the Company and TdF have agreed to maintain certain minimum ownership levels in CTSH for a period of five years). See "Business--U.K. Operations--Significant Contracts--BBC Commitment Agreement". In addition, shares may be sold to a third party, subject to a right of first refusal by the other party, after the later of (a) the second anniversary of the closing of the Roll-up, and (b) the expiration of the period for the completion of the TdF Put Right (as defined) or the Company Call Right (as defined). If CCIC purchases TdF's shares pursuant to such right of first refusal, it may elect (instead of paying the consideration in cash) to discharge the consideration by issuing its Common Stock at a discount of 15% to its market value. If the right of first refusal is not exercised, the selling shareholder must procure and offer on the same terms for the shares held by the other party. If the Company elects to issue Common Stock to TdF pursuant to the right of first refusal, TdF will be entitled to certain demand registration rights and tag along rights. TdF Put Right. TdF has the right to put its shares of CTSH to CCIC for cash (the "TdF Put Right") if there is a change of control of CCIC. Such right is exercisable if (a) TdF has not exchanged its shares pursuant to the Governance Agreement by the second anniversary of the closing of the Roll-Up, or (b) prior to the second anniversary of the closing of the Roll-Up, if TdF has ceased to be Qualified for the purposes of the Governance Agreement. The consideration payable on the exercise of the TdF Put Right will be an amount agreed between CCIC and TdF or, in the absence of agreement, the fair market value as determined by an independent appraiser. TdF Exit Right. TdF also has the right after the earlier of (a) the second anniversary of the closing of the Roll-Up, or (b) TdF ceasing to be Qualified for purposes of the Governance Agreement, to require CCIC, upon at least six months' notice, to purchase all, but not less than all, of the shares it beneficially owns in CTSH (the "TdF Exit Right"). The consideration to be paid to TdF, and the manner in which it is calculated, upon exercise of the TdF Exit Right is substantially the same as described upon exercise of the TdF Put Right. CCIC is entitled to discharge the consideration payable on the exercise of the TdF Exit Right either in cash or by issuing Common Stock to TdF at a discount of 15% to its market value. If CCIC elects to issue Common Stock to TdF on the exercise of the TdF Exit Right, TdF will be entitled to certain demand registration rights and tag-along rights. CCIC Deadlock Right. CCIC has the right to call TdF's shares of CTSH, subject to certain procedural requirements, for cash if, after the third anniversary of the closing of the Roll-Up, TdF refuses on three occasions during any consecutive six-month period to agree to the undertaking by CTSH of certain types of transactions (including acquisitions and disposals) that would fall within CTSH's core business (the "CCIC Deadlock 129

Right"). The consideration due on the exercise of the CCIC Deadlock Right is payable in cash, the fair market value of the TdF interest to be determined in the same manner described above upon exercise of the TdF Put or Exit Rights. CCIC Shotgun Right. Provided that TdF has not, pursuant to the Governance Agreement, exchanged its share ownership in CTSH for shares of CCIC, CCIC may (a) by notice expiring on August 21, 2003, or (b) at any time within 45 days of CCIC becoming aware of a TdF Change of Control (as defined in the Governance Agreement) offer to purchase TdF's shares in CTSH. TdF is required to either sell its shares or agree to purchase CCIC's shares in CTSH at the same price contained in CCIC's offer for TdF's shares of CTSH. The consummation of any transfer of shares between CCIC and TdF pursuant to any of the transfer provisions described above is subject to the fulfillment of certain conditions precedent, including obtaining all necessary governmental and regulatory consents. Termination. The Shareholders' Agreement terminates if either CCIC or TdF ceases to be qualified. CCIC remains qualified on the condition that it holds at least 10% of the share capital of CTSH. CTI Services Agreement On February 28, 1997, CTI and TdF Parent entered into a Services Agreement pursuant to which TdF Parent agreed to provide certain consulting services to CTI in consideration for a minimum annual fee of (Pounds)400,000 ($667,800) and reimbursement for reasonable out-of-pocket expenses. This agreement was amended and restated on August 21, 1998 (the "CTI Services Agreement"). TdF Parent has agreed to, among other things, provide the services of ten executives or engineers to CTI on a part-time basis and to provide a benchmarking review of CTI. In addition, TdF Parent has agreed to provide additional services relating to research, development and professional training on terms (including as to price) to be determined. Following February 28, 2003, the CTI Services Agreement will be terminable on 12-month's prior notice given by CTI to TdF. CTI Operating Agreement The following summary of the terms of the CTI Operating Agreement is subject to the negotiation of definitive documentation, although the Company expects such agreement to have the general terms described herein. Under the CTI Operating Agreement (the "CTI Operating Agreement"), the Company will be permitted to develop business opportunities relating to terrestrial wireless communications (including the transmission of radio and television broadcasting) anywhere in the world except the United Kingdom. CTI will be permitted to develop such business opportunities solely in the United Kingdom. The Company and TdF also intend to establish, pursuant to the CTI Operating Agreement, a joint venture to develop digital terrestrial transmission services in the United States. See "Business--U.S. Operations--Network Services--Broadcast Site Rental and Services". The CTI Operating Agreement will also establish a framework for the provision of business support and technical services to the Company and its subsidiaries (other than CTI) in connection with the development of any international business by the Company. TdF will have the right, if called upon to do so by the Company or CTSH, to provide all or part of such services to the Company and its subsidiaries (other than CTI) in connection with the provision of broadcast transmission services. 130

DESCRIPTION OF SECURITIES This description of the securities being offered has five parts: . Description of the Exchangeable Preferred Stock; . Description of the Exchange Debentures; . Certain Definitions; . Book-Entry, Delivery and Form; and . Registration Rights and Liquidated Damages. You should read all five parts of this Description of Securities for a description of the provisions of the instruments governing the securities, the form in which the securities are expected to be issued and certain mechanics for trading of the securities. Although this description is provided for your reference, you are strongly encouraged to read the Certificate of Designations governing the Exchangeable Preferred Stock, and the Exchange Indenture governing the Exchange Debentures for the complete terms and provisions of the securities being offered. In addition, you should be aware that the General Corporation Law of the State of Delaware also governs the Exchangeable Preferred Stock and the ability of the Company to pay dividends on the Exchangeable Preferred Stock. See "Description of Capital Stock" and "Risk Factors--Ability to Pay Dividends on the Exchangeable Preferred Stock". Description of the Exchangeable Preferred Stock You can find the definitions of certain terms used in this description under the subheading "Certain Definitions". In this description, the word "Company" refers only to Crown Castle International Corp. and not to any of its subsidiaries. The Old Preferred Stock was and the New Preferred Stock will be issued under a Certificate of Designations, Preferences and Relative, Participating, Optional and Other Special Rights of Preferred Stock and Qualifications, Limitations and Restrictions Thereof (the "Certificate of Designations"), a copy of which is filed as an exhibit to the Registration Statement of which this Prospectus is a part. The following description is a summary of the material provisions of the Certificate of Designations and does not restate that agreement in its entirety. We urge you to read the Certificate of Designations because it, and not this description, defines your rights as holders of the Exchangeable Preferred Stock. Copies of the Certificate of Designations are available as set forth below under the subheading "Additional Information". This description is qualified in its entirety by reference to the Company's Amended and Restated Certificate of Incorporation, which will include the Certificate of Designations and the definitions therein of certain terms used below. The Certificate of Designations authorized the Company to issue 400,000 shares of Exchangeable Preferred Stock with a liquidation preference of $1,000 per share (the "Liquidation Preference"). The Old Preferred Stock was and the New Preferred Stock will, when issued, be fully paid and nonassessable and Holders will have no preemptive rights in connection therewith. The liquidation preference of the Exchangeable Preferred Stock is not necessarily indicative of the price at which shares of the Exchangeable Preferred Stock will actually trade at or after the time of their issuance, and the Exchangeable Preferred Stock may trade at prices below its liquidation preference. The market price of the Exchangeable Preferred Stock can be expected to fluctuate with changes in the financial markets and economic conditions, the financial condition and prospects of the Company and other facts that generally influence the market prices of securities. 134

As of the Issue Date, all of our subsidiaries other than (1) CTSH and its subsidiaries and (2) Crown Castle Investment Corp. and Crown Castle Investment Corp. (II) and their subsidiaries, through which we intend to hold our interest in the Proposed JV, were "Restricted Subsidiaries". However, under the circumstances described below under the subheading "Certain Covenants-- Restricted Payments," we will be permitted to designate certain of our other subsidiaries as "Unrestricted Subsidiaries". Unrestricted Subsidiaries will not be subject to most of the restrictive covenants in the Certificate of Designations. Transfer Agent The transfer agent for the Exchangeable Preferred Stock is ChaseMellon Shareholder Services, L.L.C. unless and until a successor is selected by the Company (the "Transfer Agent"). Ranking The Exchangeable Preferred Stock ranks senior in right of payment to all classes or series of the Company's capital stock as to dividends and upon liquidation, dissolution or winding up of the Company. Without the consent of the Holders of at least two-thirds of the then outstanding Exchangeable Preferred Stock, the Company may not authorize, create (by way of reclassification or otherwise) or issue: (1) any class or series of capital stock of the Company ranking senior to the Exchangeable Preferred Stock ("Senior Securities"); (2) any obligation or security convertible or exchangeable into, or evidencing a right to purchase, shares of any class or series of Senior Securities. Notwithstanding the foregoing, the Company may, without the consent of the Holders of the Exchangeable Preferred Stock, authorize, create (by way of reclassification or otherwise) or issue: (1) any class or series of capital stock of the Company ranking on a parity with the Exchangeable Preferred Stock ("Parity Securities"); or (2) any obligation or security convertible or exchangeable into, or evidencing a right to purchase, shares of any class or series of Parity Securities. Dividends When the Board of Directors declares dividends out of legally available Company funds, the Holders of the Exchangeable Preferred Stock, who are Holders of record as of the preceding March 1, June 1, September 1, and December 1 (each, a "Record Date"), will be entitled to receive cumulative preferential dividends at the rate per share of 12 3/4% per annum. Dividends on the Exchangeable Preferred Stock will be payable quarterly in arrears on March 15, June 15, September 15 and December 15 of each year (each, a "Dividend Payment Date"), commencing on March 15, 1999. On or prior to December 15, 2003, the Company may, at its option, pay dividends: (1) in cash; or (2) in additional fully-paid and non-assessable shares of Exchangeable Preferred Stock (including fractional stock) having an aggregate Liquidation Preference equal to the amount of such dividends. After December 15, 2003, the Company will pay dividends in cash only. The Company does not expect to pay any dividends in cash before December 15, 2003. Dividends payable on the Exchangeable Preferred Stock will be: (1) computed on the basis of a 360-day year comprised of twelve 30-day months; and (2) accrue on a daily basis. 135

For a discussion of certain federal income tax considerations relevant to the payment of dividends on the Exchangeable Preferred Stock, see "Certain Federal Income Tax Considerations--Dividends on Exchangeable Preferred Stock". Dividends on the Exchangeable Preferred Stock will accrue whether or not: (1) the Company has earnings or profits; (2) there are funds legally available for the payment of such dividends; or (3) dividends are declared. Dividends will accumulate to the extent they are not paid on the Dividend Payment Date for the quarterly period to which they relate. Accumulated unpaid dividends will accrue dividends at the rate of 12 3/4% per annum. The Company must take all actions required or permitted under Delaware law to permit the payment of dividends on the Exchangeable Preferred Stock. For any dividend period, the Company will not declare or pay upon, or set any sum apart for the payment of dividends upon any outstanding Exchangeable Preferred Stock unless it has declared and paid upon, or declared and set apart a sufficient sum for the payment of dividends upon, all outstanding Exchangeable Preferred Stock for all preceding dividend periods. Unless the Company has declared and paid upon, or declared and set apart a sufficient sum for the payment of, full cumulative dividends on all outstanding Exchangeable Preferred Stock due for all past dividend periods, then: (1) no dividend (other than a dividend payable solely in stock of any class of stock ranking junior to the Exchangeable Preferred Stock as to the payment of dividends and as to rights in liquidation, dissolution or winding up of the affairs of the Company (any such stock, "Junior Securities")) shall be declared or paid upon, or any sum set apart for the payment of dividends upon, any Junior Securities; (2) no other distribution shall be declared or made upon, or any sum set apart for the payment of any distribution upon, any Junior Securities; (3) no Junior Securities shall be purchased, redeemed or otherwise acquired or retired for value (excluding an exchange for other Junior Securities) by the Company or any of its Restricted Subsidiaries; (4) no warrants, rights, calls or options to purchase any Junior Securities shall be directly or indirectly issued by the Company or any of its Restricted Subsidiaries; and (5) no monies shall be paid into or set apart or made available for a sinking or other like fund for the purchase, redemption or other acquisition or retirement for value of any Junior Securities by the Company or any of its Restricted Subsidiaries. Holders of the Exchangeable Preferred Stock will not be entitled to any dividends, whether payable in cash, property or stock, in excess of the full cumulative dividends as herein described. In addition, the Senior Discount Notes Indenture contains restrictions on the ability of the Company to pay dividends on the Exchangeable Preferred Stock. Moreover, existing Indebtedness and anticipated future Indebtedness of our subsidiaries and joint ventures restricts or will restrict our access to the cash flow of those entities. Any future agreements relating to Indebtedness to which the Company or any of its Subsidiaries becomes a party may contain similar restrictions and provisions. See "Risk Factors-- Substantial Leverage; Restrictions Imposed by the Terms of Our Indebtedness" and "Risk Factors--Holding Company Structure; Dependence on Dividends to Meet Cash Requirements or Pay Dividends". 136

Voting Rights Holders of record of the Exchangeable Preferred Stock will have no voting rights, except as required by law and as provided in the Certificate of Designations. Under the Certificate of Designations, the number of members of the Company's Board of Directors will immediately and automatically increase by two, and the Holders of a majority of the outstanding Exchangeable Preferred Stock, voting separately as a class together with holders of all other Parity Securities having similar voting rights, may elect two members to the Board of Directors of the Company, upon the occurrence of any of the following events (each, a "Voting Rights Triggering Event"): (1) the accumulation of accrued and unpaid dividends on the outstanding Exchangeable Preferred Stock (or after December 15, 2003, such dividends are not paid in cash) in an amount equal to six full quarterly dividends (whether or not consecutive); (2) failure by the Company or any of its Restricted Subsidiaries to comply with any mandatory redemption obligation with respect to the Exchangeable Preferred Stock, the failure to make an Asset Sale Offer or Change of Control Offer in accordance with the provisions of the Certificate of Designations and/or the failure to repurchase Exchangeable Preferred Stock pursuant to such offers; (3) failure by the Company to make a Change of Control Offer or to repurchase any Exchangeable Preferred Stock pursuant to a Change of Control Offer in reliance on the last paragraph under the caption "Repurchase at the Option of Holders--Change of Control" or failure by the Company to make an Asset Sale Offer or to repurchase any Exchangeable Preferred Stock pursuant to an Asset Sale Offer in reliance on the last paragraph under the caption "Repurchase at the Option of Holders--Asset Sales"; (4) failure by the Company or any of its Restricted Subsidiaries to comply with any of the other covenants or agreements set forth in the Certificate of Designations and the continuance of such failure for 30 consecutive days after notice to the Company by Holders of record of the Exchangeable Preferred Stock representing 25% of the outstanding shares of the Exchangeable Preferred Stock; (5) defaults under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Significant Subsidiaries (or the payment of which is guaranteed by the Company or any of its Significant Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the Closing Date, which default (i) is caused by a failure to pay the principal amount of such Indebtedness at final maturity after giving effect to any applicable grace period (a "Payment Default") or (ii) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $20.0 million or more; or (6) certain events of bankruptcy or insolvency with respect to the Company or any of its Significant Subsidiaries. The term of office of the directors elected as a result of a Voting Rights Triggering Event will continue until all dividends in arrears on the Exchangeable Preferred Stock are paid in full and all other Voting Rights Triggering Events have been cured or waived, at which time the term of office of any such directors shall terminate. In addition, as provided above under "--Ranking," the Company may not authorize, create (by way of reclassification or otherwise) or issue any Senior Securities (other than Disqualified Stock), or any obligation or security convertible into or evidencing the right to purchase Senior Securities (other than Disqualified Stock), without the consent of the Holders of at least two-thirds of the then outstanding Exchangeable Preferred Stock, in each case, voting as a single class. Under Delaware law, holders of preferred stock are entitled to vote as a class upon a proposed amendment to the certificate of incorporation if the amendment would (a) increase or decrease the par value of the shares of that class of preferred stock or (b) alter or change the powers, preferences or special rights of the shares of that class of preferred stock in a way that would affect the holders of that preferred stock adversely. 137

Exchange On any Dividend Payment Date, the Company may exchange all and not less than all of the shares of then outstanding Exchangeable Preferred Stock for the Company's 12 3/4% Exchange Debentures due 2010 (the "Exchange Debentures") if: (1) on the date of the exchange, there are no accumulated and unpaid dividends on the Exchangeable Preferred Stock (including the dividend payable on that date) or other contractual impediments to the exchange; (2) there are sufficient legally available funds; (3) the exchange does not immediately cause: (a) a Default (as defined in the Exchange Indenture); and (b) a default or event of default under any material instrument governing Indebtedness of the Company, including without limitation the Senior Discount Notes, outstanding at the time; (4) the Exchange Indenture has been qualified under the Trust Indenture Act, if qualification is required at the time of exchange; and (5) the Company has delivered a written opinion to the Exchange Trustee (as defined herein) stating that all conditions to the exchange have been satisfied. The Senior Discount Notes Indenture currently restricts the exchange of the Exchangeable Preferred Stock and may restrict the Company's ability to exchange the Exchangeable Preferred Stock in the future. See "Description of Certain Indebtedness--The Notes". In addition, existing Indebtedness and anticipated future Indebtedness of our subsidiaries and joint ventures restricts or will restrict our access to the cash flow from those entities. Any future agreements relating to Indebtedness to which we or any of our subsidiaries or joint ventures become a party may contain similar restrictions and provisions. See "Risk Factors--Holding Company Structure; Dependence on Dividends to Meet Cash Requirements or Pay Dividends". Upon any exchange pursuant to the preceding paragraph, and subject to the second succeeding sentence of this paragraph, holders of outstanding Exchangeable Preferred Stock will be entitled to receive: (1) $1.00 principal amount of Exchange Debentures for each $1.00 of the aggregate Liquidation Preference; plus (2) without duplication, any accrued and unpaid dividends. The Exchange Debentures will be: (1) issued in registered form, without coupons; (2) issued in principal amounts of $1,000 and integral multiples thereof to the extent possible; and (3) issuable in principal amounts less than $1,000 so that each holder of Exchangeable Preferred Stock will receive interests representing the entire amount of Exchange Debentures to which such holder's share of Exchangeable Preferred Stock entitle such holder, provided that the Company may pay cash in lieu of issuing an Exchange Debenture having a principal amount less than $1,000. For a description of the Exchange Debentures, see "--Description of the Exchange Debentures". The Company or a Company representative will send notice of the intention to exchange by first class mail, postage prepaid, to each Holder of record of Exchangeable Preferred Stock at its registered address not more than 60 days nor less than 30 days prior to the Exchange Date. In addition to any information required by law or 138

by the applicable rules of any exchange upon which Exchangeable Preferred Stock may be listed or admitted to trading, the notice will state: (1) the Exchange Date; (2) the place or places where certificates for such stock are to be surrendered for exchange, including any procedures applicable to exchanges to be accomplished through book-entry transfers; and (3) that dividends on the Exchangeable Preferred Stock to be exchanged will cease to accrue on the Exchange Date. If notice of any exchange has been properly given, and if on or before the Exchange Date the Exchange Debentures have been duly executed and authenticated and an amount in cash or additional Exchangeable Preferred Stock (as applicable) equal to all accrued and unpaid dividends, if any, thereon to the Exchange Date has been deposited with the Transfer Agent, then on and after the close of business on the Exchange Date: (1) the Exchangeable Preferred Stock to be exchanged will no longer be considered outstanding and may subsequently be issued in the same manner as the other authorized but unissued preferred stock, including as Parity Securities, but not as the same class as the Exchangeable Preferred Stock; and (2) all rights of the Holders as stockholders of the Company will cease, except their right to receive upon surrender of their certificates the Exchange Debentures and all accrued and unpaid dividends, if any, thereon to the Exchange Date. Mandatory Redemption On December 15, 2010 (the "Mandatory Redemption Date"), the Company will be required to redeem (subject to it having sufficient legally available funds) all outstanding Exchangeable Preferred Stock at a price in cash equal to the Liquidation Preference, plus accrued and unpaid dividends, if any, to the date of redemption. The Company will not be required to make sinking fund payments with respect to the Exchangeable Preferred Stock. The Company must take all actions required or permitted under Delaware law to permit such redemption. The Senior Discount Notes Indenture currently restricts the redemption of the Exchangeable Preferred Stock. See "Description of Certain Indebtedness-- The Notes". In addition, existing Indebtedness and anticipated future Indebtedness of our subsidiaries and joint ventures restricts or will restrict our access to the cash flow from those entities. Any future agreements relating to Indebtedness to which we or any of our subsidiaries become a party may contain similar restrictions and provisions. See "Risk Factors--Holding Company Structure; Dependence on Dividends to Meet Cash Requirements or Pay Dividends". Optional Redemption During the first 36 months after the Issue Date, the Company may on any one or more occasions redeem up to 35% of the aggregate Liquidation Preference of the Exchangeable Preferred Stock then outstanding at a redemption price of 112.750% of the Liquidation Preference thereof, plus accrued and unpaid dividends and Liquidated Damages thereon, if any, to the redemption date, with the net cash proceeds of one or more Public Equity Offerings or Strategic Equity Investments; provided that: (1) at least $130.0 million aggregate Liquidation Preference of Exchangeable Preferred Stock remains outstanding immediately after the occurrence of such redemption (excluding Exchangeable Preferred Stock held by the Company and its Subsidiaries); and (2) the redemption must occur within 60 days of the date of the closing of the Public Equity Offering or Strategic Equity Investment. Except pursuant to the preceding paragraph, the Exchangeable Preferred Stock will not be redeemable at the Company's option prior to December 15, 2003. 139

On or after December 15, 2003, the Company may redeem all or any part of the Exchangeable Preferred Stock upon not less than 30 nor more than 60 days' notice, at the redemption prices (expressed as percentages of the Liquidation Preference) set forth below plus accrued and unpaid dividends and Liquidated Damages thereon, if any, to the applicable redemption date, if redeemed during the twelve-month period beginning on December 15 of the years indicated below: Year Percentage ---- ---------- 2003.............................................................. 106.375% 2004.............................................................. 104.781% 2005.............................................................. 103.188% 2006.............................................................. 101.594% 2007 and thereafter............................................... 100.000% The Senior Discount Notes Indenture currently restricts the redemption of the Exchangeable Preferred Stock and additional indebtedness may restrict the Company's ability to redeem the Exchangeable Preferred Stock in the future. See "Description of Certain Indebtedness". Selection and Notice If less than all of the Exchangeable Preferred Stock is to be redeemed at any time, the Transfer Agent will select Exchangeable Preferred Stock for redemption as follows: (1) if the Exchangeable Preferred Stock is listed, in compliance with the requirements of the principal national securities exchange on which the Exchangeable Preferred Stock is listed; or (2) if the Exchangeable Preferred Stock is not so listed, on a pro rata basis, by lot or by such method as the Transfer Agent shall deem fair and appropriate. No Exchangeable Preferred Stock with a Liquidation Preference of $1,000 or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Exchangeable Preferred Stock to be redeemed at its registered address. Notices of redemption may not be conditional. If any Exchangeable Preferred Stock is to be redeemed in part only, the notice of redemption that relates to that Exchangeable Preferred Stock shall state the portion of the Liquidation Preference thereof to be redeemed. A new certificate with an aggregate Liquidation Preference equal to the unredeemed portion of the original certificate evidencing Exchangeable Preferred Stock presented for redemption will be issued in the name of the Holder thereof upon cancellation of the original certificate. Exchangeable Preferred Stock called for redemption becomes due on the date fixed for redemption. On and after the redemption date, dividends cease to accrue on Exchangeable Preferred Stock or portions thereof called for redemption. Liquidation Rights Each Holder of the Exchangeable Preferred Stock will be entitled to payment, out of the assets of the Company available for distribution, of an amount equal to the Liquidation Preference per Exchangeable Preferred Stock held by such Holder, plus accrued and unpaid dividends, if any, to the date fixed for liquidation, dissolution, winding up or reduction or decrease in capital stock, before any distribution is made on any Junior Securities, including, without limitation, common stock of the Company, upon any: (1) voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company; or (2) reduction or decrease in the Company's capital stock resulting in a distribution of assets to the holders of any class or series of the Company's capital stock (a "reduction or decrease in capital stock"). After payment in full of the Liquidation Preference and all accrued dividends, if any, to which Holders of Exchangeable Preferred Stock are entitled, such Holders may not further participate in any distribution of assets 140

of the Company. However, neither the voluntary sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Company nor the consolidation or merger of the Company with or into one or more corporations will be a voluntary or involuntary liquidation, dissolution or winding up of the Company or reduction or decrease in capital stock, unless such sale, conveyance, exchange or transfer is in connection with a liquidation, dissolution or winding up of the business of the Company or reduction or decrease in capital stock. The Certificate of Designations will not contain any provision requiring funds to be set aside to protect the Liquidation Preference of the Exchangeable Preferred Stock, although such Liquidation Preference will be substantially in excess of the par value of the Exchangeable Preferred Stock. Repurchase at the Option of Holders Change of Control If a Change of Control occurs, each Holder of Exchangeable Preferred Stock will have the right to require the Company to repurchase all or any part (but not any fractional shares) of such Holder's Exchangeable Preferred Stock pursuant to the offer described below (the "Change of Control Offer"). In the Change of Control Offer, the Company will offer a payment in cash equal to 101% of the aggregate Liquidation Preference of Exchangeable Preferred Stock repurchased plus accrued and unpaid dividends and Liquidated Damages thereon, if any (subject to the right of Holders of record on the relevant record date to receive dividends and Liquidated Damages, if any, due on the relevant dividend payment date), to the date of purchase (the "Change of Control Payment"). Within 30 days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Exchangeable Preferred Stock on the date specified in such notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the "Change of Control Payment Date"), pursuant to the procedures required by the Certificate of Designations and described in such notice. On the Change of Control Payment Date, the Company will, to the extent lawful: (1) accept for payment all Exchangeable Preferred Stock or portions thereof properly tendered pursuant to the Change of Control Offer; (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Exchangeable Preferred Stock or portions thereof so tendered; and (3) deliver or cause to be delivered to the Transfer Agent the Exchangeable Preferred Stock so accepted together with an Officers' Certificate stating the aggregate Liquidation Preference of Exchangeable Preferred Stock or portions thereof being purchased by the Company. The Company will promptly mail to each Holder of Exchangeable Preferred Stock so tendered the Change of Control Payment for such Exchangeable Preferred Stock, and the Transfer Agent will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new certificate representing the Exchangeable Preferred Stock equal in Liquidation Preference to any unpurchased portion of the Exchangeable Preferred Stock surrendered, if any. The Change of Control provisions described above will be applicable whether or not any other provisions of the Certificate of Designations are applicable. The Company will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations applicable to any Change of Control Offer. To the extent that the provisions of any such securities laws or securities regulations conflict with the provisions of the covenant described above, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the covenant described above by virtue thereof. The Change of Control purchase feature is a result of negotiations between the Company and the Initial Purchasers. Management has no present intention to engage in a transaction involving a Change of Control, 141

although it is possible that the Company would decide to do so in the future. Subject to the limitations discussed below, the Company could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the Certificate of Designations, but that could increase the amount of Indebtedness outstanding at such time or otherwise affect the Company's capital structure. Restrictions on the ability of the Company to incur additional Indebtedness are contained in the covenants described under "-- Certain Covenants--Incurrence of Indebtedness and Issuance of Preferred Stock". Such restrictions can only be waived with the consent of the Holders of a majority in Liquidation Preference of the Exchangeable Preferred Stock then outstanding. Except for the limitations contained in such covenants, however, the Certificate of Designations will not contain any covenants or provisions that may afford holders of the Exchangeable Preferred Stock protection in the event of certain highly leveraged transactions. The Senior Discount Notes Indenture currently prohibits the Company from repurchasing any Exchangeable Preferred Stock. In addition, existing Indebtedness and anticipated future Indebtedness of the Company's subsidiaries and joint ventures restricts or will restrict the Company's access to the cash flow from its subsidiaries and joint ventures. Any future agreements relating to Indebtedness to which the Company or any of its subsidiaries or joint ventures becomes a party may contain similar restrictions and provisions. In the event that a Change of Control occurs at a time when the Company is prohibited or prevented from repurchasing Exchangeable Preferred Stock, the Company could seek the consent of the applicable lenders to allow such repurchase or could attempt to refinance the borrowings that contain such prohibition. If the Company does not obtain such a consent or repay such borrowings, the Company will remain prohibited from repurchasing the Exchangeable Preferred Stock. In such case, the Company's failure to purchase tendered Exchangeable Preferred Stock would constitute a Voting Rights Triggering Event. Future Indebtedness of the Company and its Subsidiaries may contain prohibitions on the repurchase of the Exchangeable Preferred Stock and on the occurrence of certain events that would constitute a Change of Control or may require such Indebtedness to be repurchased upon a Change of Control. Finally, the Company's ability to pay cash to the Holders of Exchangeable Preferred Stock following the occurrence of a Change of Control may be limited by the Company's then existing financial resources, including its ability to access the cash flow of its Subsidiaries. See "Risk Factors--Repurchase of the Exchangeable Preferred Stock or the Exchange Debentures Upon a Change of Control" and "Risk Factors--Holding Company Structure; Dependence on Dividends to Meet Cash Requirements or Pay Dividends". There can be no assurance that sufficient funds will be available when necessary to make any required repurchases. The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Certificate of Designations applicable to a Change of Control Offer made by the Company and purchases all Exchangeable Preferred Stock validly tendered and not withdrawn under such Change of Control Offer. The provisions under the Certificate of Designations relative to the Company's obligation to make an offer to repurchase the Exchangeable Preferred Stock as a result of a Change of Control may be waived or modified with the written consent of the Holders of a majority in Liquidation Preference of the Exchangeable Preferred Stock then outstanding. The definition of Change of Control includes a phrase relating to the sale, lease, transfer, conveyance or other disposition of "all or substantially all" of the assets of the Company and its Restricted Subsidiaries taken as a whole. Although there is a developing body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a Holder of Exchangeable Preferred Stock to require the Company to repurchase such Exchangeable Preferred Stock as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of the Company and its Subsidiaries taken as a whole to another Person or group may be uncertain. Notwithstanding the foregoing, the Certificate of Designations will provide that the Company may not repurchase any Exchangeable Preferred Stock pursuant to this provision unless such repurchase complies with the restricted payments covenant contained in the Senior Discount Notes Indenture; provided that if the Company 142

does not make a Change of Control Offer or does not repurchase any Exchangeable Preferred Stock pursuant to a Change of Control Offer, then such failure shall constitute a Voting Rights Triggering Event. Asset Sales The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: (1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value (evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the Transfer Agent) of the assets or Equity Interests issued or sold or otherwise disposed of; and (2) except in the case of a Tower Asset Exchange, at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash: (1) any liabilities (as shown on the Company's or such Restricted Subsidiary's most recent balance sheet), of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Exchangeable Preferred Stock or any guarantee thereof) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability; and (2) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 20 days of the applicable Asset Sale (to the extent of the cash received). Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or the applicable Restricted Subsidiary may apply such Net Proceeds to: (1) reduce any Indebtedness of the Company; (2) reduce any Indebtedness of any of the Company's Restricted Subsidiaries; (3) the acquisition of all or substantially all the assets of a Permitted Business; (4) the acquisition of Voting Stock of a Permitted Business from a Person that is not a Subsidiary of the Company; provided, that, after giving effect thereto, the Company or its Restricted Subsidiary owns a majority of such Voting Stock and designates such Permitted Business as a Restricted Subsidiary; or (5) the making of a capital expenditure or the acquisition of other long- term assets that are used or useful in a Permitted Business. Pending the final application of any such Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest such Net Proceeds in any manner that is not prohibited by the Certificate of Designations. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the first sentence of this paragraph will be deemed to constitute "Excess Proceeds". When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company will be required to make an offer to all holders of Senior Discount Notes and may be required to make such offer to holders of other Indebtedness of the Company then outstanding (a "Senior Asset Sale Offer") to purchase the maximum principal amount of the Senior Discount Notes and such other Indebtedness, if applicable, that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount or accreted value thereof, as the case may be, plus accrued and unpaid interest to the date of purchase, in accordance with the procedures set forth in the Senior Discount Notes Indenture and in the instruments governing such other Indebtedness. To the extent that the aggregate amount of Senior Discount Notes and such other Indebtedness tendered pursuant to a Senior Asset Sale Offer is less than the remaining Excess Proceeds ("Remaining Excess Proceeds") and the sum of (A) such amount of 143

Remaining Excess Proceeds and (B) the Remaining Excess Proceeds from any subsequent Senior Asset Sale Offers exceeds $3.0 million, the Company will be required to make an offer to all Holders of Exchangeable Preferred Stock and all holders of Parity Securities containing provisions similar to those set forth in the Certificate of Designations with respect to offers to purchase with the proceeds of sales of assets (an "Asset Sale Offer") to purchase the maximum Liquidation Preference of Exchangeable Preferred Stock and such Parity Securities that may be purchased out of such Remaining Excess Proceeds, at an offer price in cash in an amount equal to 100% of the Liquidation Preference thereof plus accrued and unpaid dividends and Liquidated Damages thereon, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive dividends and Liquidated Damages, if any, due on the relevant Dividend Payment Date), in accordance with the procedures set forth in the Certificate of Designations and such Parity Securities. To the extent that any Remaining Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by the Certificate of Designations. If the aggregate Liquidation Preference of Exchangeable Preferred Stock and such Parity Securities tendered into such Asset Sale Offer surrendered by Holders thereof exceeds the amount of Remaining Excess Proceeds, the Transfer Agent shall select the Exchangeable Preferred Stock and such Parity Securities to be purchased on a pro rata basis. Upon completion of such offer to purchase, the amount of Excess Proceeds shall be reset at zero. The Asset Sale provisions described above will be applicable whether or not any other provisions of the Certificate of Designations are applicable. The Company will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations applicable to any Asset Sale Offer. To the extent that the provisions of any such securities laws or securities regulations conflict with the provisions of the covenant described above, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the covenant described above by virtue thereof. The Senior Discount Notes Indenture currently prohibits the Company form repurchasing any Exchangeable Preferred Stock. In addition, existing Indebtedness and anticipated future Indebtedness of our subsidiaries and joint ventures restricts or will restrict our access to the cash flow from those entities. Any future agreements relating to Indebtedness to which we or any of our subsidiaries or joint ventures become a party may contain similar restrictions and provisions. Notwithstanding the foregoing, the Certificate of Designations will provide that the Company may not repurchase any Exchangeable Preferred Stock pursuant to this provision unless such repurchase complies with the restricted payments covenant contained in the Senior Discount Notes Indenture; provided that if the Company does not make an Asset Sale Offer or does not repurchase any Exchangeable Preferred Stock pursuant to an Asset Sale Offer, then such failure shall constitute a Voting Rights Triggering Event. Certain Covenants Restricted Payments The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly: (1) declare or pay any dividend or make any other payment or distribution on account of the Company's Junior Securities or any warrants, options or other rights to acquire Junior Securities (other than any debt security that is convertible into, or exchangeable for, Junior Securities) or any of the Company's Restricted Subsidiaries' Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company's Junior Securities or any warrants, options or other rights to acquire Junior Securities (other than any debt security that is convertible into, or exchangeable for, Junior Securities) or any of the Company's Restricted Subsidiaries' Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or to the Company or a Restricted Subsidiary of the Company); 144

(2) purchase, redeem or otherwise acquire or retire for value (including without limitation, in connection with any merger or consolidation involving the Company) any Junior Securities of the Company or any warrants, options or other rights to acquire Junior Securities (other than any debt security that is convertible into, or exchangeable for, Junior Securities) or any Equity Interests of any direct or indirect parent of the Company (other than any such Equity Interests owned by the Company or any Restricted Subsidiary of the Company and other than the Exchangeable Preferred Stock); or (3) make any Restricted Investment, (all such payments and other actions set forth in clauses (1) through (3) above being collectively referred to as "Restricted Payments"), unless, at the time of and after giving effect to such Restricted Payment: (1) no Voting Rights Triggering Event shall have occurred and be continuing or would occur as a consequence thereof; and (2) the Company would have been permitted to incur at least $1.00 of additional indebtedness pursuant to the Debt to Adjusted Consolidated Cash Flow Ratio test set forth in the first paragraph of the covenant described below under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock"; provided that the Company and its Restricted Subsidiaries will not be required to comply with this clause (2) in order to make any Restricted Investment; and (3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (2) and (3) of the next succeeding paragraph), is less than the sum, without duplication, of: (a) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from the beginning of the first fiscal quarter commencing after the Issue Date to the end of the Company's most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus (b) 100% of the aggregate net cash proceeds received by the Company since the Issue Date as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Company (other than Disqualified Stock and except to the extent such net cash proceeds are used to incur new Indebtedness outstanding pursuant to clause (10) of the second paragraph of the covenant described below under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock") or from the issue or sale of Disqualified Stock or debt securities of the Company that have been converted into such Equity Interests (other than Equity Interests (or Disqualified Stock or convertible debt securities) sold to a Subsidiary of the Company and other than Disqualified Stock or convertible debt securities that have been converted into Disqualified Stock); plus (c) to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or otherwise liquidated or repaid for cash, the lesser of (A) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (B) the initial amount of such Restricted Investment; plus (d) to the extent that any Unrestricted Subsidiary of the Company and all of its Subsidiaries are designated as Restricted Subsidiaries after the Issue Date, the lesser of (A) the fair market value of the Company's Investments in such Subsidiaries as of the date of such designation, or (B) the sum of (x) the fair market value of the Company's Investments in such Subsidiaries as of the date on which such Subsidiaries were originally designated as Unrestricted Subsidiaries and (y) the amount of any Investments made in such Subsidiaries subsequent to such designation (and treated as Restricted Payments) by the Company or any Restricted Subsidiary; provided that: (i) in the event the Unrestricted Subsidiaries designated as Restricted Subsidiaries are CTSH and its Subsidiaries, the references in clauses (A) and (B) of this clause (d) to fair market value of the Company's Investments in such Subsidiaries shall mean the amount by which the fair market 145

value of all such Investments exceeds 34.3% of the fair market value of CTSH and its Subsidiaries as a whole; and (ii) in the event the Unrestricted Subsidiaries designated as Restricted Subsidiaries are CCAIC and its Subsidiaries, the references in clauses (A) and (B) of this clause (d) to fair market value of the Company's Investments in such Subsidiaries shall mean the amount by which the fair market value of all such Investments exceeds $250.0 million; plus (e) 50% of any dividends received by the Company or a Restricted Subsidiary after the Issue Date from an Unrestricted Subsidiary of the Company, to the extent that such dividends were not otherwise included in Consolidated Net Income of the Company for such period. The foregoing provisions will not prohibit: (1) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of the Certificate of Designations; (2) the making of any Investment or the redemption, repurchase, retirement, defeasance or other acquisition of any Equity Interests of the Company in exchange for, or out of the net cash proceeds of the sale after the Issue Date (other than to a Subsidiary of the Company) of, any Equity Interests of the Company (other than any Disqualified Stock); provided that such net cash proceeds are not used to incur new Indebtedness pursuant to clause (10) of the second paragraph of the covenant described below under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock"); and provided further that, in each such case, the amount of any such net cash proceeds that are so utilized shall be excluded from clause (3) (b) of the preceding paragraph; (3) the payment of any dividend by a Restricted Subsidiary of the Company to the holders of its Equity Interests on a pro rata basis; or (4) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any member of the Company's (or any of its Restricted Subsidiaries') management pursuant to any management equity subscription agreement or stock option agreement in effect as of the Issue Date; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed (a) $500,000 in any twelve-month period and (b) $5.0 million in the aggregate. The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a Voting Rights Triggering Event; provided that in no event shall the businesses operated by the Company's Restricted Subsidiaries as of November 20, 1997 be transferred to or held by an Unrestricted Subsidiary. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be Restricted Payments at the time of such designation and will reduce the amount available for Restricted Payments under the first paragraph of this covenant. All such outstanding Investments will be deemed to constitute Investments in an amount equal to the fair market value of such Investments at the time of such designation. Such designation will only be permitted if such Restricted Payment would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may designate any Unrestricted Subsidiary to be a Restricted Subsidiary if such designation would not cause a Voting Rights Triggering Event. The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or the applicable Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any property, assets or Investments required by this covenant to be determined shall be determined by the Board of Directors whose resolution with respect thereto shall be delivered to the Transfer Agent. 146

Incurrence of Indebtedness and Issuance of Preferred Stock The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, "incur") any Indebtedness (including Acquired Debt) and that the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, that the Company may incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock and the Company's Restricted Subsidiaries may incur Indebtedness if, in each case, the Company's Debt to Adjusted Consolidated Cash Flow Ratio at the time of incurrence of such Indebtedness or the issuance of such Disqualified Stock, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds therefrom as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been no greater than 7.5 to 1. The provisions of the first paragraph of this covenant will not apply to the incurrence of any of the following items of Indebtedness or to the issuance of any of the following items of Disqualified Stock or preferred stock (collectively, "Permitted Debt"): (1) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness (including Indebtedness under Credit Facilities) in an aggregate principal amount (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) at any one time outstanding not to exceed the greater of (x) $200.0 million less the aggregate amount of all Net Proceeds of Asset Sales applied to repay Indebtedness under a Credit Facility pursuant to the covenant described above under the caption "--Repurchase at the Option of Holders--Asset Sales" and (y) 70% of the Eligible Receivables that are outstanding as of such date of incurrence; (2) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness; (3) the issuance by the Company of preferred stock represented by the Exchangeable Preferred Stock and the incurrence by the Company of Indebtedness represented by the Exchange Debentures; (4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Company or such Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any other Indebtedness incurred pursuant to this clause (4), not to exceed $10.0 million at any one time outstanding; (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund Indebtedness of the Company or any of its Restricted Subsidiaries or Disqualified Stock of the Company (other than intercompany Indebtedness) that was permitted by the Certificate of Designations to be incurred under the first paragraph hereof or clauses (2) or (3) or this clause (5) of this paragraph; (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, that (A) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (B) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be; (7) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing or hedging interest rate risk with respect to any floating rate 147

Indebtedness that is permitted by the terms of the Certificate of Designations to be outstanding or currency exchange risk; (8) the guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of the Certificate of Designations; (9) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt in connection with the acquisition of assets or a new Subsidiary and the incurrence by the Company's Restricted Subsidiaries of Indebtedness as a result of the designation of an Unrestricted Subsidiary as a Restricted Subsidiary; provided that, in the case of any such incurrence of Acquired Debt, such Acquired Debt was incurred by the prior owner of such assets or such Restricted Subsidiary prior to such acquisition by the Company or one of its Restricted Subsidiaries and was not incurred in connection with, or in contemplation of, such acquisition by the Company or one of its Restricted Subsidiaries; and provided further that, in the case of any incurrence pursuant to this clause (9), as a result of such acquisition by the Company or one of its Restricted Subsidiaries, the Company's Debt to Adjusted Consolidated Cash Flow Ratio at the time of incurrence of such Acquired Debt, after giving pro forma effect to such incurrence as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been less than the Company's Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such incurrence; (10) the incurrence by the Company of Indebtedness not to exceed, at any one time outstanding, the sum of (i) 2.0 times the aggregate net cash proceeds plus (ii) 1.0 times the fair market value of non-cash proceeds (evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the Transfer Agent), in each case, from the issuance and sale, other than to a Subsidiary, of Equity Interests (other than Disqualified Stock) of the Company since the Issue Date (less the amount of such proceeds used to make Restricted Payments as provided in clause (3)(b) of the first paragraph or clause (2) of the second paragraph of the covenant described above under the caption "--Restricted Payments"); provided that such Indebtedness does not mature prior to the Stated Maturity of the Exchangeable Preferred Stock and the Weighted Average Life to Maturity of such Indebtedness is longer than that of the Exchangeable Preferred Stock; and (11) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness and/or the issuance by the Company of Disqualified Stock in an aggregate principal amount, accreted value or liquidation preference, as applicable, at any time outstanding, not to exceed an amount equal to $100.0 million less the aggregate amount of all Investments made pursuant to clause (12) of the definition of Permitted Investments; provided that, notwithstanding the foregoing, the aggregate principal amount, accreted value or liquidation preference, as applicable, permitted to be incurred or issued pursuant to this clause (11) shall not be reduced to less than $25.0 million. For purposes of determining compliance with this covenant, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (11) above or is entitled to be incurred pursuant to the first paragraph of this covenant, the Company shall, in its sole discretion, classify (or later reclassify in whole or in part) such item of Indebtedness in any manner that complies with this covenant. Accrual of interest, accretion or amortization of original issue discount and the payment of interest in the form of additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of this covenant. Dividend and Other Payment Restrictions Affecting Subsidiaries The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to 148

(1) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries on its Capital Stock or with respect to any other interest or participation in, or measured by, its profits; (2) pay any indebtedness owed to the Company or any of its Restricted Subsidiaries; (3) make loans or advances to the Company or any of its Restricted Subsidiaries; or (4) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries. However, the foregoing restrictions will not apply to encumbrances or restrictions existing under or by reason of: (1) Existing Indebtedness or Indebtedness under the Senior Credit Facility, in each case as in effect on the Issue Date, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in the applicable series of Existing Indebtedness or in the Senior Credit Facility, in each case as in effect on the Issue Date; (2) encumbrances and restrictions applicable to any Unrestricted Subsidiary, as the same are in effect as of the date on which such Subsidiary becomes a Restricted Subsidiary, and as the same may be amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in the applicable series of Indebtedness of such Subsidiary as in effect on the date on which such Subsidiary becomes a Restricted Subsidiary; (3) any Indebtedness (incurred in compliance with the covenant under the heading "--Incurrence of Indebtedness and Issuance of Preferred Stock") or any agreement pursuant to which such Indebtedness is issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant contained in such Indebtedness or agreement and such encumbrance or restriction is not materially more disadvantageous to the holders of the Exchangeable Preferred Stock than is customary in comparable financings (as determined by the Company) and the Company determines that any such encumbrance or restriction will not materially affect the Company's ability to pay dividends or the Liquidation Preference on the Exchangeable Preferred Stock; (4) the Certificate of Designations; (5) applicable law; (6) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Certificate of Designations to be incurred; (7) by reason of customary non-assignment provisions in leases or licenses entered into in the ordinary course of business; (8) purchase money obligations for property acquired in the ordinary course of business that impose restrictions of the nature described in clause (4) in the prior paragraph on the property so acquired; (9) the provisions of agreements governing Indebtedness incurred pursuant to clause (4) of the second paragraph of the covenant described above under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock"; (10) any agreement for the sale of a Restricted Subsidiary that restricts that Restricted Subsidiary pending its sale; 149

(11) Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; (12) Liens that limit the right of the debtor to transfer the assets subject to such Liens; (13) provisions with respect to the disposition or distribution of assets or property in joint venture agreements and other similar agreements; and (14) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business. Merger, Consolidation or Sale of Assets The Company may not consolidate or merge with or into (whether or not the Company is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to another corporation, Person or entity unless: (1) the Company is the surviving corporation or the entity or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia; (2) the entity or Person formed by or surviving any such consolidation or merger (if other than the Company) or the entity or Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Exchangeable Preferred Stock and the Certificate of Designations; (3) immediately after such transaction no Voting Rights Triggering Event exists; and (4) except in the case of a merger of the Company with or into a Wholly Owned Restricted Subsidiary of the Company and except in the case of a merger entered into solely for the purpose of reincorporating the Company in another jurisdiction, (a) in the case of a merger or consolidation in which the Company is the surviving corporation, the Company's Debt to Adjusted Consolidated Cash Flow Ratio, at the time of such transaction after giving pro forma effect thereto as if such transaction had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been less than the Company's Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such transaction, or (b) in the case of any other such transaction the Debt to Adjusted Consolidated Cash Flow of the entity or Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made, at the time of such transaction after giving pro forma effect thereto as if such transaction had occurred at the beginning of the most recently ended four full fiscal quarter period of such entity or Person for which internal financial statements are available, would have been less than the Company's Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such transaction; provided that for purposes of determining the Debt to Adjusted Consolidated Cash Flow Ratio of any such entity or Person for purposes of this clause (b) such entity or Person shall be substituted for the Company in the definition of Debt to Adjusted Consolidated Cash Flow Ratio and the defined terms included therein under the caption "--Certain Definitions". Transactions with Affiliates The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets 150

from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless: (1) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and (2) the Company delivers to the Transfer Agent: (a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $1.0 million, a resolution of the Board of Directors set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with clause (i) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors; and (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, an opinion as to the fairness to the Holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. The following items shall not be deemed to be Affiliate Transactions and therefore will not be subject to the provisions of the prior paragraph: (1) any employment arrangements with any executive officer of the Company or a Restricted Subsidiary that is entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and consistent with compensation arrangements of similarly situated executive officers at comparable companies engaged in Permitted Businesses; (2) transactions between or among the Company and/or its Restricted Subsidiaries; (3) payment of directors fees in an aggregate annual amount not to exceed $25,000 per Person; (4) Restricted Payments that are permitted by the provisions of the Certificate of Designations described above under the caption "--Restricted Payments"; (5) the issuance or sale of Equity Interests (other than Disqualified Stock) of the Company; and (6) transactions pursuant to the provisions of the Governance Agreement, the Rights Agreement, the Stockholders' Agreement, the CTSH Shareholders' Agreement, the CTI Services Agreement, the CTI Operating Agreement and the Crown Transition Agreements, as the same are in effect on the Issue Date. Limitation on Issuances and Sales of Capital Stock of Restricted Subsidiaries The Company: (1) will not, and will not permit any Restricted Subsidiary of the Company to, transfer, convey, sell, lease or otherwise dispose of any Equity Interests in any Restricted Subsidiary of the Company to any Person (other than the Company or a Wholly Owned Restricted Subsidiary of the Company); and (2) will not permit any Restricted Subsidiary of the Company to issue any of its Equity Interests (other than, if necessary, shares of its Capital Stock constituting directors' qualifying shares) to any Person other than to the Company or a Wholly Owned Restricted Subsidiary of the Company, unless, in each such case: (a) as a result of such transfer, conveyance, sale, lease or other disposition or issuance such Restricted Subsidiary no longer constitutes a Subsidiary and (b) the cash Net Proceeds from such transfer, conveyance, sale, lease or other disposition or issuance are applied in accordance with the covenant described above under the caption "-- Repurchase at the Option of Holders--Asset Sales". Senior Subordinated Debt So long as any Exchangeable Preferred Stock is outstanding, the Company shall not incur any Indebtedness, other than the Exchange Debentures and New Exchange Debentures, that is expressly made subordinated in right 151

of payment to any Senior Debt unless such Indebtedness, by its terms and by the terms of any agreement or instrument pursuant to which such Indebtedness is outstanding, is expressly made pari passu with, or subordinate in right of payment to, the Exchange Debentures pursuant to provisions substantially similar to those contained in the Exchange Indenture; provided that the foregoing limitations shall not apply to distinctions between categories of Senior Debt that exist by reason of any Liens or Guarantees arising or created in respect of some but not all Senior Debt. Business Activities The Company will not, and will not permit any Subsidiary to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Company and its Subsidiaries taken as a whole. Reports Whether or not required by the rules and regulations of the Securities and Exchange Commission (the "Commission"), so long as any Exchangeable Preferred Stock is outstanding, the Company will furnish to the Holders of Exchangeable Preferred Stock: (1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries (showing in reasonable detail, in the footnotes to the financial statements and in "Management's Discussion and Analysis of Financial Condition and Results of Operations" (in each case to the extent not prohibited by the Commission's rules and regulations), (a) the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company and (b) the Tower Cash Flow for the most recently completed fiscal quarter and the Adjusted Consolidated Cash Flow for the most recently completed four-quarter period) and, with respect to the annual information only, a report thereon by the Company's certified independent accountants; and (2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports, in each case within the time periods specified in the Commission's rules and regulations. In addition, following the consummation of the exchange offer contemplated by the Registration Rights Agreement, whether or not required by the rules and regulations of the Commission, the Company will file a copy of all such information and reports with the Commission for public availability within the time periods specified in the Commission's rules and regulations (unless the Commission will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. Transfer and Exchange A Holder may transfer or exchange Exchangeable Preferred Stock in accordance with the Certificate of Designations. The Registrar and the Transfer Agent may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law. The Company is not required to transfer or exchange any shares of Exchangeable Preferred Stock selected for redemption. Also, the Company is not required to transfer or exchange any share of Exchangeable Preferred Stock for a period of 15 days before a selection of Exchangeable Preferred Stock to be redeemed. The registered Holder of a share of Exchangeable Preferred Stock will be treated as the owner of it for all purposes. Amendment, Supplement and Waiver Except as provided in the next two succeeding paragraphs, the Certificate of Designations or the Exchangeable Preferred Stock may be amended or supplemented with the consent of the Holders of at least a 152

majority in aggregate Liquidation Preference of the Exchangeable Preferred Stock then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Exchangeable Preferred Stock), and any existing default or compliance with any provision of the Certificate of Designations or the Exchangeable Preferred Stock may be waived with the consent of the Holders of a majority in aggregate Liquidation Preference of the then outstanding Exchangeable Preferred Stock (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Exchangeable Preferred Stock). Without the consent of each Holder affected, an amendment or waiver may not (with respect to any shares of Exchangeable Preferred Stock held by a non- consenting Holder): (1) alter the voting rights with respect to the Exchangeable Preferred Stock or reduce the number of shares of Exchangeable Preferred Stock whose Holders must consent to an amendment, supplement or waiver; (2) reduce the Liquidation Preference of or change the Mandatory Redemption Date of any Exchangeable Preferred Stock or alter the provisions with respect to the redemption (but not any required repurchase in connection with an Asset Sale Offer or Change of Control Offer) of the Exchangeable Preferred Stock; (3) reduce the rate of or change the time for payment of dividends on any Exchangeable Preferred Stock; (4) waive a default in the payment of dividends on the Exchangeable Preferred Stock; (5) make any Exchangeable Preferred Stock payable in any form or money other than that stated in the Certificate of Designations; (6) waive a redemption payment (but not any payment upon a required repurchase in connection with an Asset Sale Offer or Change of Control Offer) with respect to any Exchangeable Preferred Stock; or (7) make any change in the foregoing amendment and waiver provisions. Notwithstanding the foregoing, without the consent of any Holder of Exchangeable Preferred Stock, the Company may (to the extent permitted by Delaware law) amend or supplement the Certificate of Designations: (1) to cure any ambiguity, defect or inconsistency; (2) to provide for uncertificated Exchangeable Preferred Stock in addition to or in place of certificated Exchangeable Preferred Stock; (3) to provide for the assumption of the Company's obligations to Holders of Exchangeable Preferred Stock in the case of a merger or consolidation; or (4) to make any change that would provide any additional rights or benefits to the Holders of Exchangeable Preferred Stock or that does not adversely affect the legal rights under the Certificate of Designations of any such Holder. Reissuance Exchangeable Preferred Stock redeemed or otherwise acquired by the Company will assume the status of authorized but unissued preferred stock and may thereafter be reissued in the same manner as the other authorized but unissued preferred stock, including as Parity Securities, but not as the same class as the Exchangeable Preferred Stock. 153

Description of the Exchange Debentures You can find the definitions of certain terms used in this description under the subheading "Certain Definitions". In this description, the word "Company" refers only to Crown Castle International Corp. and not to any of its subsidiaries. The Exchange Debentures will, if and when issued, be issued pursuant to an Indenture (the "Exchange Indenture") between the Company and United States Trust Company of New York, as trustee (the "Trustee"). The terms of the Exchange Debentures include those stated in the Exchange Indenture and those made part of the Exchange Indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The following description is a summary of the material provisions of the Exchange Indenture. It does not restate the Exchange Indenture in its entirety. We urge you to read the Exchange Indenture because it, and not this description, defines your rights as holders of these Exchange Debentures. Copies of the proposed form of Exchange Indenture are available as set forth below under the subheading "Additional Information". These Exchange Debentures: . will be general unsecured obligations of the Company; . will be subordinated in right of payment to all existing and future Senior Debt of the Company; and . will be senior in right of payment to all existing and future subordinated Indebtedness of the Company other than future subordinated Indebtedness that ranks on a parity with the Exchange Debentures. As of September 30, 1998, we had total Senior Debt of approximately $232.8 million. As indicated above and as discussed in detail below under the subheading "Subordination", payments on the Exchange Debentures will be subordinated to the prior payment in full in cash or Cash Equivalents (other than cash equivalents of the type referred to in clauses (3) and (4) of the definition thereof) of all Senior Debt. The Exchange Indenture will permit us to incur additional Senior Debt. In addition, our only significant asset is the outstanding capital stock of our subsidiaries, and we rely on payments from our subsidiaries to be able to meet our obligations. In the event of a bankruptcy, liquidation or reorganization of any of our subsidiaries, such subsidiaries would pay the holders of their debt and their trade creditors before they would be able to distribute any of their assets to us. As of the Issue Date, all of our subsidiaries (other than CTSH and its subsidiaries and Crown Castle Investment Corp. and its subsidiaries) will be "Restricted Subsidiaries". However, under the circumstances described below under the subheading "Certain Covenants--Restricted Payments", we will be permitted to designate certain of our other Subsidiaries as "Unrestricted Subsidiaries". Unrestricted Subsidiaries will not be subject to most of the restrictive covenants in the Exchange Indenture. Principal, Maturity and Interest The Company will issue Exchange Debentures in denominations of $1,000 and integral multiples of $1,000. The Exchange Debentures will mature on December 15, 2010. Interest on these Exchange Debentures will accrue at the rate of 12 3/4% per annum and will be payable semi-annually in arrears on June 15 and December 15. The Company will make each interest payment to the Holders of record of these Exchange Debentures on the immediately preceding June 1 and December 1. On or prior to December 15, 2003, the Company may, at its option, pay interest: (1) in cash; or (2) in additional Exchange Debentures having an aggregate principal amount equal to the amount of such interest. 154

After December 15, 2003, the Company will pay interest in cash only. The Company does not expect to pay any interest in cash before December 15, 2003. Interest on these Exchange Debentures will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Methods of Receiving Payments on the Exchange Debentures If a Holder has given wire transfer instructions to the Company, the Company will make all principal, premium and interest and Liquidated Damages, if any, payments on those Exchange Debentures in accordance with those instructions. All other payments on these Exchange Debentures will be made at the office or agency of the Paying Agent and Registrar within the City and State of New York unless the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register of Holders. Paying Agent and Registrar for the Exchange Debentures The Exchange Trustee will initially act as Paying Agent and Registrar. The Company may change the Paying Agent or Registrar without prior notice to the Holders of the Exchange Debentures, and the Company or any of its Subsidiaries may act as Paying Agent or Registrar. Transfer and Exchange A Holder may transfer or exchange Exchange Debentures in accordance with the Exchange Indenture. The Registrar and the Exchange Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Exchange Indenture. The Company is not required to transfer or exchange any Senior Subordinated Exchange Debenture selected for redemption. Also, the Company is not required to transfer or exchange any Senior Subordinated Exchange Debenture for a period of 15 days before a selection of Exchange Debentures to be redeemed. The registered Holder of a Senior Subordinated Exchange Debenture will be treated as the owner of it for all purposes. Subordination The payment of principal, premium, interest, Liquidated Damages, if any, and any other Obligations on, or relating to, the Exchange Debentures will be subordinated to the prior payment in full in cash or Cash Equivalents (other than cash equivalents of the type referred to in clauses (3) and (4) of the definition thereof) of all Senior Debt of the Company. The holders of Senior Debt will be entitled to receive payment in full in cash or Cash Equivalents (other than cash equivalents of the type referred to in clauses (3) and (4) of the definition thereof) of all Obligations due in respect of Senior Debt (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Debt) before the Holders of Exchange Debentures will be entitled to receive any payment or distribution of any kind or character with respect to any Obligations on, or relating to, the Exchange Debentures (except that Holders of Exchange Debentures may receive and retain Permitted Junior Securities and payments made from the trust described under the caption "--Legal Defeasance and Covenant Defeasance" so long as the deposit of amounts therein satisfied the relevant conditions specified in the Exchange Indenture at the time of such deposit), in the event of any distribution to creditors of the Company: (1) in a liquidation or dissolution of the Company; (2) in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property; 155

(3) in an assignment for the benefit of creditors; or (4) in any marshalling of the Company's assets and liabilities. The Company also may not make any payment or distribution of any kind or character with respect to any Obligations on, or with respect to, the Exchange Debentures or acquire any of the Exchange Debentures for cash or property or otherwise (except in Permitted Junior Securities or from the trust described under the caption "--Legal Defeasance and Covenant Defeasance") if: (1) a payment default on Designated Senior Debt occurs and is continuing beyond any applicable period of grace; or (2) any other default occurs and is continuing on Designated Senior Debt that permits holders of the Designated Senior Debt to accelerate its maturity immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods and the Exchange Trustee receives a notice of such default (a "Payment Blockage Notice") from the holders of such Designated Senior Debt or their Representative. Payments on the Exchange Debentures may and shall be resumed: (1) in the case of a payment default, upon the date on which such default is cured or waived; or (2) in case of a nonpayment default, upon the earlier of (x) the date on which all nonpayment defaults are cured or waived, (y) 179 days after the date of delivery of the applicable Payment Blockage Notice or (z) the date on which the Exchange Trustee receives notice from the holders of such Designated Senior Debt or their Representative rescinding the Payment Blockage Notice, unless the maturity of any Designated Senior Debt has been accelerated. No new Payment Blockage Notice may be delivered by the holders of any Designated Senior Debt or their Representative unless and until 360 days have elapsed since the effectiveness of the immediately prior Payment Blockage Notice. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Exchange Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice unless such default shall have been cured or waived for a period of not less than 90 consecutive days. The Company must promptly notify holders of Senior Debt if payment of the Exchange Debentures are accelerated because of an Event of Default. As a result of the subordination provisions described above, in the event of a bankruptcy, liquidation or reorganization of the Company, Holders of Exchange Debentures may recover less ratably than creditors of the Company who are holders of Senior Debt. See "Risk Factors--Subordination of the Exchangeable Preferred Stock". Optional Redemption During the first 36 months after the Issue Date, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of Exchange Debentures then outstanding at a redemption price of 112.750% of the principal amount thereof, plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the redemption date, with the net cash proceeds of one or more Public Equity Offerings or Strategic Equity Investments; provided that: (1) at least $162.5 million aggregate principal amount of Exchange Debentures remains outstanding immediately after the occurrence of such redemption (excluding Exchange Debentures held by the Company and its Subsidiaries); and (2) the redemption must occur within 60 days of the date of the closing of the Public Equity Offering or Strategic Equity Investment. 156

Except pursuant to the preceding paragraph, the Exchange Debentures will not be redeemable at the Company's option prior to December 15, 2003. On or after December 15, 2003, the Company may redeem all or any part of the Exchange Debentures upon not less than 30 nor more than 60 days' notice, at the redemption prices (expressed as percentages of the principal amount) set forth below plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the applicable redemption date, if redeemed during the twelve-month period beginning on December 15 of the years indicated below: Year Percentage ---- ---------- 2003.............................................................. 106.375% 2004.............................................................. 104.781% 2005.............................................................. 103.188% 2006.............................................................. 101.594% 2007 and thereafter............................................... 100.000% The Senior Discount Notes Indenture currently restricts the redemption of the Exchange Debentures and additional indebtedness may restrict the Company's ability to redeem the Exchange Debentures in the future. See "Description of Certain Indebtedness". Selection and Notice If less than all of the Exchange Debentures are to be redeemed at any time, the Exchange Trustee will select Exchange Debentures for redemption as follows: (1) if the Exchange Debentures are listed, in compliance with the requirements of the principal national securities exchange on which the Exchange Debentures are listed; or (2) If the Exchange Debentures are not so listed, on a pro rata basis, by lot or by such method as the Exchange Trustee shall deem fair and appropriate. No Senior Subordinated Exchange Debenture of $1,000 or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Exchange Debentures to be redeemed at its registered address. Notices of redemption may not be conditional. If any Exchange Debentures are to be redeemed in part only, the notice of redemption that relates to that Exchange Debentures shall state the portion of the principal amount thereof to be redeemed. A new certificate with an aggregate principal amount equal to the unredeemed portion of the original certificate evidencing Exchange Debentures presented for redemption will be issued in the name of the Holder thereof upon cancellation of the original certificate. Exchange Debentures called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on Exchange Debentures or portions thereof called for redemption. Mandatory Redemption The Company is not required to make mandatory redemption or sinking fund payments with respect to the Exchange Debentures. Repurchase at the Option of Holders Change of Control If a Change of Control occurs, each Holder of Exchange Debentures will have the right to require the Company to repurchase all or any part (but not any fractional shares) of such Holder's Exchange Debentures 157

pursuant to the offer described below (the "Change of Control Offer"). In the Change of Control Offer, the Company will offer a payment in cash equal to 101% of the aggregate principal amount of Exchangeable Preferred Stock repurchased plus accrued and unpaid interest and Liquidated Damages thereon, if any (subject to the right of Holders of record on the relevant record date to receive dividends and Liquidated Damages, if any, due on the relevant dividend payment date), to the date of purchase (the "Change of Control Payment"). Within 30 days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Exchange Debentures on the date specified in such notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the "Change of Control Payment Date"), pursuant to the procedures required by the Exchange Indenture and described in such notice. On the Change of Control Payment Date, the Company will, to the extent lawful: (1) accept for payment all Exchange Debentures or portions thereof properly tendered pursuant to the Change of Control Offer; (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Exchange Debentures or portions thereof so tendered; and (3) deliver or cause to be delivered to the Exchange Trustee the Exchange Debentures so accepted together with an Officers' Certificate stating the aggregate principal amount of Exchange Debentures or portions thereof being purchased by the Company. The Company will promptly mail to each Holder of Exchange Debentures so tendered the Change of Control Payment for such Exchange Debentures, and the Exchange Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new certificate representing the Exchange Debentures equal in principal amount to any unpurchased portion of the Exchange Debentures surrendered, if any. The Change of Control provisions described above will be applicable whether or not any other provisions of the Exchange Indenture are applicable. The Company will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations applicable to any Change of Control Offer. To the extent that the provisions of any such securities laws or securities regulations conflict with the provisions of the covenant described above, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the covenant described above by virtue thereof. The Change of Control purchase feature is a result of negotiations between the Company and the Initial Purchasers. Management has no present intention to engage in a transaction involving a Change of Control, although it is possible that the Company would decide to do so in the future. Subject to the limitations discussed below, the Company could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the Exchange Indenture, but that could increase the amount of Indebtedness outstanding at such time or otherwise affect the Company's capital structure. Restrictions on the ability of the Company to incur additional Indebtedness are contained in the covenants described under "--Certain Covenants-- Incurrence of Indebtedness and Issuance of Preferred Stock". Such restrictions can only be waived with the consent of the Holders of a majority in principal amount of the Exchange Debentures then outstanding. Except for the limitations contained in such covenants, however, the Exchange Indenture will not contain any covenants or provisions that may afford holders of the Exchange Debentures protection in the event of certain highly leveraged transactions. The Senior Discount Notes Indenture currently prohibits the Company from repurchasing any Exchange Debentures. In addition, existing Indebtedness and anticipated future Indebtedness of the Company's subsidiaries and joint ventures restricts or will restrict the Company's access to the cash flow from its subsidiaries and joint ventures. Any future agreements relating to Indebtedness to which the Company or any of its subsidiaries or joint ventures become a party may contain similar restrictions and provisions. In the event that a Change of Control occurs at a time when the Company is prohibited or prevented from repurchasing Exchange Debentures, 158

the Company seek the consent of the applicable lenders to allow such repurchase or could attempt to refinance the borrowings that contain such prohibition. If the Company does not obtain such a consent or repay such borrowings, the Company will remain prohibited from repurchasing the Exchange Debentures. In such case, the Company's failure to purchase tendered Exchange Debentures would constitute an Event of Default under the Exchange Indenture which would, in turn, constitute a default under the Senior Discount Notes Indenture. Future Indebtedness of the Company and its Subsidiaries may contain prohibitions on the repurchase of the Exchange Debentures and on the occurrence of certain events that would constitute a Change of Control or may require such Indebtedness to be repurchased upon a Change of Control. Finally, the Company's ability to pay cash to the Holders of Exchange Debentures following the occurrence of a Change of Control may be limited by the Company's then existing financial resources, including its ability to access the cash flow of its Subsidiaries. See "Risk Factors--Repurchase of the Exchangeable Preferred Stock or the Exchange Debentures Upon a Change of Control" and "Risk Factors--Holding Company Structure; Dependence on Dividends to Meet Cash Requirements or Pay Dividends". There can be no assurance that sufficient funds will be available when necessary to make any required repurchases. The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Exchange Indenture applicable to a Change of Control Offer made by the Company and purchases all Exchange Debentures validly tendered and not withdrawn under such Change of Control Offer. The provisions under the Exchange Indenture relative to the Company's obligation to make an offer to repurchase the Exchange Debentures as a result of a Change of Control may be waived or modified with the written consent of the Holders of a majority in principal amount of the Exchange Debentures then outstanding. The definition of Change of Control includes a phrase relating to the sale, lease, transfer, conveyance or other disposition of "all or substantially all" of the assets of the Company and its Restricted Subsidiaries taken as a whole. Although there is a developing body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a Holder of Exchange Debentures to require the Company to repurchase such Exchange Debentures as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of the Company and its Subsidiaries taken as a whole to another Person or group may be uncertain. Asset Sales The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: (1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value (evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the Exchange Trustee) of the assets or Equity Interests issued or sold or otherwise disposed of; and (2) except in the case of a Tower Asset Exchange, at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash: (1) any liabilities (as shown on the Company's or such Restricted Subsidiary's most recent balance sheet), of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Exchange Debentures or any guarantee thereof) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability; and (2) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 20 days of the applicable Asset Sale (to the extent of the cash received). 159

Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or the applicable Restricted Subsidiary may apply such Net Proceeds to: (1) reduce any Indebtedness of the Company that constitutes Senior Debt; (2) reduce any Indebtedness of any of the Company's Restricted Subsidiaries; (3) the acquisition of all or substantially all the assets of a Permitted Business; (4) the acquisition of Voting Stock of a Permitted Business from a Person that is not a Subsidiary of the Company; provided, that, after giving effect thereto, the Company or its Restricted Subsidiary owns a majority of such Voting Stock and designates such Permitted Business as a Restricted Subsidiary; or (5) the making of a capital expenditure or the acquisition of other long- term assets that are used or useful in a Permitted Business. Pending the final application of any such Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest such Net Proceeds in any manner that is not prohibited by the Exchange Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the first sentence of this paragraph will be deemed to constitute "Excess Proceeds". When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company will be required to make an offer to all holders of Senior Discount Notes and may be required to make such offer to holders of other Senior Debt of the Company then outstanding (a "Senior Asset Sale Offer") to purchase the maximum principal amount of the Senior Discount Notes and such other Senior Debt, if applicable, that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount or accreted value thereof, as the case may be, plus accrued and unpaid interest to the date of purchase, in accordance with the procedures set forth in the Senior Discount Notes Indenture and in the instruments governing such other Senior Debt. To the extent that the aggregate amount of Senior Discount Notes and such other Senior Debt tendered pursuant to a Senior Asset Sale Offer is less than the remaining Excess Proceeds ("Remaining Excess Proceeds") and the sum of (A) such amount of Remaining Excess Proceeds and (B) the Remaining Excess Proceeds from any subsequent Senior Asset Sale Offers exceeds $3.0 million, the Company will be required to make an offer to all Holders of Exchange Debentures and all holders of other senior subordinated Indebtedness of the Company containing provisions similar to those set forth in the Exchange Indenture with respect to offers to purchase with the proceeds of sales of assets (an "Asset Sale Offer") to purchase the maximum principal amount of Exchange Debentures and such other senior subordinated Indebtedness of the Company that may be purchased out of the Remaining Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest and Liquidated Damages, if any, due on the relevant interest payment date), in accordance with the procedures set forth in the Exchange Indenture and such other senior subordinated Indebtedness of the Company. To the extent that any Remaining Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by the Exchange Indenture. If the aggregate principal amount of Exchange Debentures and such other senior subordinated Indebtedness of the Company tendered into such Asset Sale Offer surrendered by Holders thereof exceeds the amount of Remaining Excess Proceeds, the Exchange Trustee shall select the Exchange Debentures and such other senior subordinated Indebtedness to be purchased on a pro rata basis. Upon completion of such offer to purchase, the amount of Excess Proceeds shall be reset at zero. The Asset Sale provisions described above will be applicable whether or not any other provisions of the Exchange Indenture are applicable. The Company will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations applicable to any Asset Sale Offer. To the extent that the provisions of any such securities laws or securities regulations conflict with the provisions of the covenant described above, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the covenant described above by virtue thereof. 160

The Senior Discount Notes Indenture currently prohibits the Company form repurchasing any Exchange Debentures. In addition, existing Indebtedness and anticipated future Indebtedness of our subsidiaries and joint ventures restricts or will restrict our access to the cash flow from those entities. Any future agreements relating to Indebtedness to which we or any of our subsidiaries or joint ventures become a party may contain similar restrictions and provisions. Certain Covenants Restricted Payments The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly: (1) declare or pay any dividend or make any other payment or distribution on account of the Company's or any of its Restricted Subsidiaries' Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company's or any of its Restricted Subsidiaries' Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or to the Company or a Restricted Subsidiary of the Company); (2) purchase, redeem or otherwise acquire or retire for value (including without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company or any direct or indirect parent of the Company (other than any such Equity Interests owned by the Company or any Restricted Subsidiary of the Company and other than the Exchangeable Preferred Stock); (3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the Exchange Debentures, except a payment of interest or the payment of principal at Stated Maturity; or (4) make any Restricted Investment, (all such payments and other actions set forth in clauses (1) through (4) above being collectively referred to as "Restricted Payments"), unless, at the time of and after giving effect to such Restricted Payment: (1) no Default shall have occurred and be continuing or would occur as a consequence thereof; and (2) the Company would have been permitted to incur at least $1.00 of additional indebtedness pursuant to the Debt to Adjusted Consolidated Cash Flow Ratio test set forth in the first paragraph of the covenant described below under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock"; provided that the Company and its Restricted Subsidiaries will not be required to comply with this clause (2) in order to make any Restricted Investment; and (3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (2), (3) and (4) of the next succeeding paragraph), is less than the sum, without duplication, of: (a) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from the beginning of the first fiscal quarter commencing after the Issue Date to the end of the Company's most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus (b) 100% of the aggregate net cash proceeds received by the Company since the Issue Date as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Company (other than Disqualified Stock and except to the extent such net cash proceeds are used to incur new Indebtedness outstanding pursuant to clause (10) of the second paragraph of the covenant described below under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock") or from the issue or sale of Disqualified Stock or debt securities of the Company that have been converted into 161

such Equity Interests (other than Equity Interests (or Disqualified Stock or convertible debt securities) sold to a Subsidiary of the Company and other than Disqualified Stock or convertible debt securities that have been converted into Disqualified Stock); plus (c) to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or otherwise liquidated or repaid for cash, the lesser of (A) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (B) the initial amount of such Restricted Investment; plus (d) to the extent that any Unrestricted Subsidiary of the Company and all of its Subsidiaries are designated as Restricted Subsidiaries after the Issue Date, the lesser of (A) the fair market value of the Company's Investments in such Subsidiaries as of the date of such designation, or (B) the sum of (x) the fair market value of the Company's Investments in such Subsidiaries as of the date on which such Subsidiaries were originally designated as Unrestricted Subsidiaries and (y) the amount of any Investments made in such Subsidiaries subsequent to such designation (and treated as Restricted Payments) by the Company or any Restricted Subsidiary; provided that: (i) in the event the Unrestricted Subsidiaries designated as Restricted Subsidiaries are CTSH and its Subsidiaries, the references in clauses (A) and (B) of this clause (d) to fair market value of the Company's Investments in such Subsidiaries shall mean the amount by which the fair market value of all such Investments exceeds 34.3% of the fair market value of CTSH and its Subsidiaries as a whole; and (ii) in the event the Unrestricted Subsidiaries designated as Restricted Subsidiaries are CCAIC and its Subsidiaries, the references in clauses (A) and (B) of this clause (d) to fair market value of the Company's Investments in such Subsidiaries shall mean the amount by which the fair market value of all such Investments exceeds $250.0 million; plus (e) 50% of any dividends received by the Company or a Restricted Subsidiary after the Issue Date from an Unrestricted Subsidiary of the Company, to the extent that such dividends were not otherwise included in Consolidated Net Income of the Company for such period. The foregoing provisions will not prohibit: (1) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of the Exchange Indenture; (2) the making of any Investment or the redemption, repurchase, retirement, defeasance or other acquisition of any subordinated Indebtedness or Equity Interests of the Company in exchange for, or out of the net cash proceeds of the sale after the Issue Date (other than to a Subsidiary of the Company) of, any Equity Interests of the Company (other than any Disqualified Stock); provided that such net cash proceeds are not used to incur new Indebtedness pursuant to clause (x) of the second paragraph of the covenant described below under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock"); and provided further that, in each such case, the amount of any such net cash proceeds that are so utilized shall be excluded from clause (3) (b) of the preceding paragraph; (3) the defeasance, redemption, repurchase or other acquisition of subordinated Indebtedness with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness; (4) the payment of any dividend by a Restricted Subsidiary of the Company to the holders of its common Equity Interests on a pro rata basis; or (5) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any member of the Company's (or any of its Restricted Subsidiaries') management pursuant to any management equity subscription agreement or stock option agreement in effect as of the Issue Date; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed (a) $500,000 in any twelve-month period and (b) $5.0 million in the aggregate. 162

The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a Default; provided that in no event shall the businesses operated by the Company's Restricted Subsidiaries as of November 20, 1997 be transferred to or held by an Unrestricted Subsidiary. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be Restricted Payments at the time of such designation and will reduce the amount available for Restricted Payments under the first paragraph of this covenant. All such outstanding Investments will be deemed to constitute Investments in an amount equal to the fair market value of such Investments at the time of such designation. Such designation will only be permitted if such Restricted Payment would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may designate any Unrestricted Subsidiary to be a Restricted Subsidiary if such designation would not cause a Default. The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or the applicable Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any property, assets or Investments required by this covenant to be determined shall be determined by the Board of Directors whose resolution with respect thereto shall be delivered to the Exchange Trustee. Incurrence of Indebtedness and Issuance of Preferred Stock The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, incur any Indebtedness (including Acquired Debt) and that the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, that the Company may incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock and the Company's Restricted Subsidiaries may incur Indebtedness if, in each case, the Company's Debt to Adjusted Consolidated Cash Flow Ratio at the time of incurrence of such Indebtedness or the issuance of such Disqualified Stock, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds therefrom as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been no greater than 7.5 to 1. The provisions of the first paragraph of this covenant will not apply to the incurrence of any of the following items of Indebtedness or to the issuance of any of the following items of Disqualified Stock or preferred stock (collectively, "Exchange Debentures Permitted Debt"): (1) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness (including Indebtedness under Credit Facilities) in an aggregate principal amount (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) at any one time outstanding not to exceed the greater of (x) $200.0 million less the aggregate amount of all Net Proceeds of Asset Sales applied after the Issue Date to repay Indebtedness under a Credit Facility pursuant to the covenant described above under the caption "--Repurchase at the Option of Holders--Asset Sales" and (y) 70% of the Eligible Receivables that are outstanding as of such date of incurrence; (2) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness; (3) the incurrence by the Company of Indebtedness represented by the Exchange Debentures; (4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Company or such Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any other Indebtedness incurred pursuant to this clause (4), not to exceed $10.0 million at any one time outstanding; 163

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund Indebtedness of the Company or any of its Restricted Subsidiaries or Disqualified Stock of the Company (other than intercompany Indebtedness) that was permitted by the Exchange Indenture to be incurred under the first paragraph hereof or clauses (2) or (3) or this clause (5) of this paragraph; (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, that (i) if the Company is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Exchange Debentures and (ii)(A) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (B) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be; (7) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing or hedging interest rate risk with respect to any floating rate Indebtedness that is permitted by the terms of the Exchange Indenture to be outstanding or currency exchange risk; (8) the guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of the Exchange Indenture; (9) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt in connection with the acquisition of assets or a new Subsidiary and the incurrence by the Company's Restricted Subsidiaries of Indebtedness as a result of the designation of an Unrestricted Subsidiary as a Restricted Subsidiary; provided that, in the case of any such incurrence of Acquired Debt, such Acquired Debt was incurred by the prior owner of such assets or such Restricted Subsidiary prior to such acquisition by the Company or one of its Restricted Subsidiaries and was not incurred in connection with, or in contemplation of, such acquisition by the Company or one of its Restricted Subsidiaries; and provided further that, in the case of any incurrence pursuant to this clause (9), as a result of such acquisition by the Company or one of its Restricted Subsidiaries, the Company's Debt to Adjusted Consolidated Cash Flow Ratio at the time of incurrence of such Acquired Debt, after giving pro forma effect to such incurrence as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been less than the Company's Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such incurrence; (10) the incurrence by the Company of Indebtedness not to exceed, at any one time outstanding, the sum of (i) 2.0 times the aggregate net cash proceeds plus (ii) 1.0 times the fair market value of non-cash proceeds (evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the Exchange Trustee), in each case, from the issuance and sale, other than to a Subsidiary, of Equity Interests (other than Disqualified Stock) of the Company since the Issue Date (less the amount of such proceeds used to make Restricted Payments as provided in clause (3)(b) of the first paragraph or clause (2) of the second paragraph of the covenant described above under the caption "--Restricted Payments"); provided that such Indebtedness does not mature prior to the Stated Maturity of the Exchange Debentures and the Weighted Average Life to Maturity of such Indebtedness is longer than that of the Exchange Debentures; and (11) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness and/or the issuance by the Company of Disqualified Stock in an aggregate principal amount, accreted value or liquidation preference, as applicable, at any time outstanding, not to exceed an amount equal to $100.0 million less the aggregate amount of all Investments made pursuant to clause (12) of the definition of Permitted Investments; provided that, notwithstanding the foregoing, the aggregate principal amount, 164

accreted value or liquidation preference, as applicable, permitted to be incurred or issued pursuant to this clause (11) shall not be reduced to less than $25.0 million. For purposes of determining compliance with this covenant, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Exchange Debentures Permitted Debt described in clauses (1) through (11) above or is entitled to be incurred pursuant to the first paragraph of this covenant, the Company shall, in its sole discretion, classify (or later reclassify in whole or in part) such item of Indebtedness in any manner that complies with this covenant. Any Indebtedness incurred pursuant to clause (1) of the second paragraph under the caption "Incurrence of Indebtedness and Issuance of Preferred Stock" in the Certificate of Designations will be deemed to have been incurred under clause (1) above on the Exchange Date. Accrual of interest, accretion or amortization of original issue discount and the payment of interest in the form of additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of this covenant. Dividend and Other Payment Restrictions Affecting Subsidiaries The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to (1) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries on its Capital Stock or with respect to any other interest or participation in, or measured by, its profits; (2) pay any indebtedness owed to the Company or any of its Restricted Subsidiaries; (3) make loans or advances to the Company or any of its Restricted Subsidiaries; or (4) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries. However, the foregoing restrictions will not apply to encumbrances or restrictions existing under or by reason of: (1) Existing Indebtedness or Indebtedness under the Senior Credit Facility, in each case as in effect on the Issue Date, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in the applicable series of Existing Indebtedness or in the Senior Credit Facility, in each case as in effect on the Issue Date; (2) encumbrances and restrictions applicable to any Unrestricted Subsidiary, as the same are in effect as of the date on which such Subsidiary becomes a Restricted Subsidiary, and as the same may be amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in the applicable series of Indebtedness of such Subsidiary as in effect on the date on which such Subsidiary becomes a Restricted Subsidiary; (3) any Indebtedness (incurred in compliance with the covenant under the heading "--Incurrence of Indebtedness and Issuance of Preferred Stock") or any agreement pursuant to which such Indebtedness is issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant contained in such Indebtedness or agreement and such encumbrance or restriction is not materially more disadvantageous to the holders of the Exchange Debentures than is customary in comparable financings (as determined by the Company) and the Company determines that any such encumbrance or restriction will not materially affect the Company's ability to pay dividends or the Liquidation Preference on the Exchange Debentures; (4) the Exchange Indenture and the Exchange Debentures; (5) applicable law; 165

(6) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Exchange Indenture to be incurred; (7) by reason of customary non-assignment provisions in leases or licenses entered into in the ordinary course of business; (8) purchase money obligations for property acquired in the ordinary course of business that impose restrictions of the nature described in clause (4) in the prior paragraph on the property so acquired; (9) the provisions of agreements governing Indebtedness incurred pursuant to clause (4) of the second paragraph of the covenant described above under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock"; (10) any agreement for the sale of a Restricted Subsidiary that restricts that Restricted Subsidiary pending its sale; (11) Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; (12) Liens that limit the right of the debtor to transfer the assets subject to such Liens; (13) provisions with respect to the disposition or distribution of assets or property in joint venture agreements and other similar agreements; and (14) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business. Merger, Consolidation or Sale of Assets The Company may not consolidate or merge with or into (whether or not the Company is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to another corporation, Person or entity unless: (1) the Company is the surviving corporation or the entity or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia; (2) the entity or Person formed by or surviving any such consolidation or merger (if other than the Company) or the entity or Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Exchange Debentures and the Exchange Indenture pursuant to a supplemental indenture in a form reasonably satisfactory to the Exchange Trustee; (3) immediately after such transaction no Default exists; and (4) except in the case of a merger of the Company with or into a Wholly Owned Restricted Subsidiary of the Company and except in the case of a merger entered into solely for the purpose of reincorporating the Company in another jurisdiction, the Company or the entity or Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made will, at the time of such transaction after giving pro forma effect thereto as if such transaction had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Debt to Adjusted Consolidated Cash Flow Ratio test set forth in the first paragraph of the covenant described above under the caption "--Incurrence of Indebtedness and Issuance of Preferred Stock". 166

Transactions with Affiliates The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless: (1) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and (2) the Company delivers to the Exchange Trustee: (a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $1.0 million, a resolution of the Board of Directors set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with clause (i) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors; and (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, an opinion as to the fairness to the Holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. The following items shall not be deemed to be Affiliate Transactions and therefore will not be subject to the provisions of the prior paragraph: (1) any employment arrangements with any executive officer of the Company or a Restricted Subsidiary that is entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and consistent with compensation arrangements of similarly situated executive officers at comparable companies engaged in Permitted Businesses; (2) transactions between or among the Company and/or its Restricted Subsidiaries; (3) payment of directors fees in an aggregate annual amount not to exceed $25,000 per Person; (4) Restricted Payments that are permitted by the provisions of the Exchange Indenture described above under the caption "--Restricted Payments"; (5) the issuance or sale of Equity Interests (other than Disqualified Stock) of the Company; and (6) transactions pursuant to the provisions of the Governance Agreement, the Rights Agreement, the Stockholders' Agreement, the CTSH Shareholders' Agreement, the CTI Services Agreement, the CTI Operating Agreement and the Crown Transition Agreements, as the same are in effect on the Issue Date.

Senior Subordinated Debt So long as any Exchange Debentures are outstanding, the Company will not incur any Indebtedness that is expressly made subordinated in right of payment to any Senior Debt unless such Indebtedness, by its terms and by the terms of any agreement or instrument pursuant to which such Indebtedness is outstanding, is expressly made pari passu with, or subordinate in right of payment to, the Exchange Debentures pursuant to provisions substantially similar to those contained in the Exchange Indenture; provided that the foregoing limitations shall not apply to distinctions between categories of Senior Debt that exist by reason of any Liens or Guarantees arising or created in respect of some but not all Senior Debt. Business Activities The Company will not, and will not permit any Subsidiary to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Company and its Subsidiaries taken as a whole. Reports Whether or not required by the rules and regulations of the Securities and Exchange Commission (the "Commission"), so long as any Exchange Debentures are outstanding, the Company will furnish to the Holders of Exchange Debentures: (1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries (showing in reasonable detail, in the footnotes to the financial statements and in "Management's Discussion and Analysis of Financial Condition and Results of Operations" (in each case to the extent not prohibited by the Commission's rules and regulations), (a) the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company and (b) the Tower Cash Flow for the most recently completed fiscal quarter and the Adjusted Consolidated Cash Flow for the most recently completed four-quarter period) and, with respect to the annual information only, a report thereon by the Company's certified independent accountants; and (2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports, in each case within the time periods specified in the Commission's rules and regulations. In addition, following the consummation of the exchange offer contemplated by the Registration Rights Agreement, whether or not required by the rules and regulations of the Commission, the Company will file a copy of all such information and reports with the Commission for public availability within the time periods specified in the Commission's rules and regulations (unless the Commission will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. Transfer and Exchange A Holder may transfer or exchange Exchange Debentures in accordance with the Exchange Indenture. The Registrar and the Exchange Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law. The Company is not required to transfer or exchange any Senior Subordinated Exchange Debenture selected for redemption. Also, the Company is not required to transfer or exchange any Senior Subordinated Exchange Debenture for a period of 15 days before a selection of Exchange Debentures to be redeemed. The registered Holder of a Senior Subordinated Exchange Debenture will be treated as the owner of it for all purposes. 168

Notwithstanding the foregoing, without the consent of any Holder of Exchange Debentures, the Company and the Exchange Trustee may amend or supplement the Exchange Indenture or the Exchange Debentures: (1) to cure any ambiguity, defect or inconsistency; (2) to provide for uncertificated Exchange Debentures in addition to or in place of certificated Exchange Debentures; 169

(3) to provide for the assumption of the Company's obligations to Holders of Exchange Debentures in the case of a merger or consolidation; (4) to make any change that would provide any additional rights or benefits to the Holders of Exchange Debentures or that does not adversely affect the legal rights under the Exchange Indenture of any such Holder; or (5) to comply with requirements of the Commission in order to effect or maintain the qualification of the Exchange Indenture under the Trust Indenture Act. Events of Default and Remedies Each of the following is an Event of Default: (1) default for 30 days in the payment when due of interest on, or Liquidated Damages with respect to, the Exchange Debentures; (2) default in payment when due of the principal of or premium, if any, on the Exchange Debentures; (3) failure by the Company or any of its Subsidiaries for 30 days after notice to comply with the provisions described under the caption "--Certain Covenants--Merger, Consolidation or Sale of Assets" or failure by the Company to consummate a Change of Control Offer or Asset Sale Offer in accordance with the provisions of the Exchange Indenture applicable thereto; (4) failure by the Company or any of its Subsidiaries for 60 days after notice to comply with any of its other agreements in the Exchange Indenture or the Exchange Debentures; (5) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Significant Subsidiaries (or the payment of which is guaranteed by the Company or any of its Significant Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the Issue Date, which default (a) is caused by a failure to pay principal of or premium, if any, or interest on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a "Payment Default") or (b) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $20.0 million or more; (6) failure by the Company or any of its Significant Subsidiaries to pay final judgments aggregating in excess of $20.0 million, which judgments are not paid, discharged or stayed for a period of 60 consecutive days; or (7) certain events of bankruptcy or insolvency with respect to the Company or any of its Significant Subsidiaries. If any Event of Default occurs and is continuing, the Exchange Trustee or the Holders of at least 25% of the aggregate principal amount of the then outstanding Exchange Debentures may declare all the Exchange Debentures to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to the Company, all outstanding Exchange Debentures will become due and payable without further action or notice. Holders of the Exchange Debentures may not enforce the Exchange Indenture or the Exchange Debentures except as provided in the Exchange Indenture. Subject to certain limitations, Holders of a majority of the aggregate principal amount of the then outstanding Exchange Debentures may direct the Exchange Trustee in its exercise of any trust or power. The Holders of a majority of the aggregate principal amount of the Exchange Debentures then outstanding by notice to the Exchange Trustee may on behalf of the Holders of all of the Exchange Debentures waive any existing Default or Event of Default and its consequences under the Exchange Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Exchange Debentures. 170

The Exchange Indenture provides that if a Default occurs and is continuing and is known to the Exchange Trustee, the Exchange Trustee must mail to each holder of the Exchange Debentures notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Senior Subordinated Exchange Debenture, the Exchange Trustee may withhold notice if and so long as a committee of its trust officers determines that withholding notice is not opposed to the interest of the holders of the Exchange Debentures. In addition, the Company is required to deliver to the Exchange Trustee, within 90 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year. The Company is also required to deliver to the Exchange Trustee, forthwith after the occurrence thereof, written notice of any event that would constitute a Default, the status thereof and what action the Company is taking or proposes to take in respect thereof. No Personal Liability of Directors, Officers, Employees and Stockholders No director, officer, employee, incorporator or stockholder of the Company, as such, shall have any liability for any obligations of the Company under the Exchange Debentures, the Exchange Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Exchange Debentures by accepting a Senior Subordinated Exchange Debenture waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Exchange Debentures. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Commission that such a waiver is against public policy. Legal Defeasance and Covenant Defeasance The Company may, at its option and at any time, elect to have all of its obligations discharged with respect to the outstanding Exchange Debentures ("Legal Defeasance") except for: (1) the rights of Holders of outstanding Exchange Debentures to receive payments in respect of the principal of, premium, if any, and interest and Liquidated Damages on such Exchange Debentures when such payments are due from the trust referred to below; (2) the Company's obligations with respect to the Exchange Debentures concerning issuing temporary Exchange Debentures, registration of Exchange Debentures, mutilated, destroyed, lost or stolen Exchange Debentures and the maintenance of an office or agency for payment and money for security payments held in trust; (3) the rights, powers, trusts, duties and immunities of the Exchange Trustee and the Company's obligations in connection therewith; and (4) the Legal Defeasance provisions of the Exchange Indenture. In addition, the Company may, at its option and at any time, elect to have the obligations of the Company released with respect to certain covenants that are described in the Exchange Indenture ("Covenant Defeasance") and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the Exchange Debentures. In the event Covenant Defeasance occurs, certain events (not including non-payment and bankruptcy, receivership, rehabilitation and insolvency events with respect to the Company) described under "--Events of Default and Remedies" will no longer constitute an Event of Default with respect to the Exchange Debentures. In order to exercise either Legal Defeasance or Covenant Defeasance: (1) the Company must irrevocably deposit with the Exchange Trustee, in trust, for the benefit of the Holders of the Exchange Debentures, cash in United States dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest and Liquidated Damages on the outstanding Exchange Debentures on the stated maturity or on the applicable redemption 171

date, as the case may be, and the Company must specify whether the Exchange Debentures are being defeased to maturity or to a particular redemption date; (2) in the case of Legal Defeasance, the Company shall have delivered to the Exchange Trustee an opinion of counsel in the United States reasonably acceptable to the Exchange Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the Holders of the outstanding Exchange Debentures will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; (3) in the case of Covenant Defeasance, the Company shall have delivered to the Exchange Trustee an opinion of counsel in the United States reasonably acceptable to the Exchange Trustee confirming that the Holders of the outstanding Exchange Debentures will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) or insofar as Events of Default from bankruptcy or insolvency events with respect to the Company are concerned, at any time in the period ending on the 91st day after the date of deposit; (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the Exchange Indenture) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound; (6) the Company must have delivered to the Exchange Trustee an opinion of counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally; (7) the Company must deliver to the Exchange Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Exchange Debentures over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and (8) the Company must deliver to the Exchange Trustee an Officers' Certificate and an opinion of counsel, each stating that all conditions precedent provided for relating to the Legal Defeasance or the Covenant Defeasance have been complied with. Concerning the Exchange Trustee The Exchange Indenture contains certain limitations on the rights of the Exchange Trustee, should it become a creditor of the Company, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Exchange Trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Commission for permission to continue or resign. The Holders of a majority of the aggregate principal amount of the then outstanding Exchange Debentures will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Exchange Trustee, subject to certain exceptions. The Exchange Indenture provides that in case an Event of Default shall occur (which shall not be cured), the Exchange Trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the Exchange Trustee will be under no obligation to exercise any of its rights or powers under the Exchange Indenture at the request of any Holder of Exchange Debentures, unless such Holder shall have offered to the Exchange Trustee security and indemnity satisfactory to it against any loss, liability or expense. 172

The Global Certificates will be deposited upon issuance with the Transfer Agent as custodian for DTC, in New York, New York, and registered in the name of DTC or its nominee, in each case for credit to an account of a direct or indirect participant in DTC as described below. Except as set forth below, the Global Certificates may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Certificates may not be exchanged for Exchangeable Preferred Stock in certificated form except in the limited circumstances described below. See "--Depositary Procedures--Exchange of Book-Entry Exchangeable Preferred Stocks for Certificated Securities." Except in the limited circumstances described below, owners of beneficial interests in the Global Certificates will not be entitled to receive physical delivery of Certificated Securities (as defined below). Transfers of beneficial interest in the Global Certificates will be subject to the applicable rules and procedures of DTC and its direct or indirect participants, which may change from time to time. Initially, the Exchange Agent will act as Paying Agent and Registrar. The Exchangeable Preferred Stock may be presented for registration of transfer and exchange at the offices of the Registrar. Depository Procedures The following description of the operations and procedures of DTC are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them from time to time. The Company takes no responsibility for these operations and procedures and urges investors to contact the system or their participants directly to discuss these matters. DTC is a limited-purpose trust company created to hold securities for its participating organizations (collectively, the "Participants") and to facilitate the clearance and settlement of transactions in those securities between Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers (including the Initial Purchasers), banks, trust companies, clearing corporations and certain other organizations. Access to DTC's system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Participant, either directly or indirectly (collectively, the "Indirect Participants"). Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through the Participants or the Indirect Participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the Participants and Indirect Participants. Pursuant to procedures established by DTC: (1) upon deposit of the Global Certificates, DTC will credit the accounts of Participants designated by the Initial Purchasers with portions of the principal amount of the Global Certificates; and (2) ownership of such interests in the Global Certificates will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC (with respect to the Participants) or by the Participants and the Indirect Participants (with respect to other owners of beneficial interest in the Global Certificates). Investors in the Global Certificates may hold their interests therein directly through DTC, if they are Participants in such system, or indirectly through organizations (including Euroclear and Cedel Bank) which are Participants in such system. Investors in the Regulation S Global Certificates must initially hold their interests therein through Euroclear or Cedel Bank, if they are participants in such systems, or indirectly through organizations which are participants in such systems. After the expiration of the Restricted Period (but not earlier), investors may also hold interests in the Regulation S Global Certificates through organizations other than Euroclear and Cedel Bank that are Participants in the DTC system. Euroclear and Cedel Bank will hold interests 186

in the Regulation S Global Certificates on behalf of their Participants through customers' securities accounts in their respective names on the books of their respective depositaries, which are Morgan Guaranty Trust Company of New York, Brussels office, as operator of Euroclear, and Citibank, N.A. as operator of Cedel. The depositaries, in turn, will hold such interests in the Regulation S Global Certificates in customers' securities accounts in the depositaries' names on the books of DTC. All interests in a Global Certificate, including those held through Euroclear or Cedel Bank, may be subject to the procedures and requirements of DTC. Those interests held by Euroclear or Cedel Bank may be also be subject to the procedures and requirements of such system. The laws of some states require that certain persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interest in a Global Certificate to such persons may be limited to that extent. Because DTC can act only on behalf of Participants, which in turn act on behalf of Indirect Participants and certain banks, the ability of a person having a beneficial interest in a Global Certificate to pledge such interest to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests. For certain other restrictions on the transferability of the Preferred Stock or the Exchange Debentures, as applicable, see "--Exchange of Book-Entry Securities for Certificated Securities", "--Exchange of Certificated Securities for Book-Entry Securities" and "--Exchanges between Regulation S Certificates and Rule 144A Certificates." Because DTC can act only on behalf of Participants, which in turn act on behalf of Indirect Participants and certain banks, the ability of a person having beneficial interests in a Global Certificate to pledge such interests to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests. Except as described below, owners of interest in the Global Certificates will not have Exchangeable Preferred Stock or Exchange Debentures, as applicable, registered in their names, will not receive physical delivery of Exchangeable Preferred Stock or Exchange Debentures, as applicable, in certificated form and will not be considered the registered owners or "Holders" thereof under the Certificate of Designations or the Exchange Indenture, as applicable, for any purpose. Payments in respect of the principal of, and premium, if any, Liquidated Damages, if any, and interest on a Global Certificate registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered Holder under the Certificate of Designations or the Exchange Indenture, as applicable. Under the terms of the Certificate of Designations and the Exchange Indenture, the Company and the Transfer Agent or Exchange Trustee, as applicable, will treat the persons in whose names the Exchangeable Preferred Stock or Exchange Debentures, as applicable, including the Global Certificates, are registered as the owners thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. Consequently, neither the Company, the Transfer Agent or the Exchange Trustee nor any of their respective agents has or will have any responsibility or liability for: (1) any aspect of DTC's records or any Participant's or Indirect Participant's records relating to or payments made on account of beneficial ownership interest in the Global Certificates, or for maintaining, supervising or reviewing any of DTC's records or any Participant's or Indirect Participant's records relating to the beneficial ownership interests in the Global Certificates; or (2) any other matter relating to the actions and practices of DTC or any of its Participants or Indirect Participants. DTC's current practice, upon receipt of any payment in respect of securities such as the Exchangeable Preferred Stock (including dividends) or the Exchange Debentures (including principal and interest), as applicable, is to credit the accounts of the relevant Participants with the payment on the payment date, in amounts proportionate to their respective holdings in the principal amount of beneficial interest in the relevant security as shown on the records of DTC unless DTC has reason to believe it will not receive payment on such payment date. 187

Payments by the Participants and the Indirect Participants to the beneficial owners of Exchangeable Preferred Stock or Exchange Debentures, as applicable, will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the Transfer Agent, the Exchange Trustee or the Company. None of the Company, the Transfer Agent or the Exchange Trustee will be liable for any delay by DTC or any of its Participants in identifying the beneficial owners of the Exchangeable Preferred Stock or Exchange Debentures, as applicable, and the Company, the Transfer Agent and the Exchange Trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes. Except for trades involving only Euroclear and Cedel Bank participants, interests in the Global Certificates are expected to be eligible to trade in DTC's Same-Day Funds Settlement System and secondary market trading activity in such interests will, therefore, settle in immediately available funds, subject in all cases to the rules and procedures of DTC and its Participants. See "--Same Day Settlement and Payment". DTC will take any action permitted to be taken by a holder of Exchangeable Preferred Stock or Exchange Debentures, as applicable, only at the direction of one or more Participants to whose account DTC has credited the interests in the Global Certificates and only in respect of such portion of the aggregate principal amount of the Exchangeable Preferred Stock or Exchange Debentures, as applicable, as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default under the Exchange Debentures, DTC reserves the right to exchange the Global Certificates for legended Securities in certificated form, and to distribute such Certificates to its Participants. Although DTC has agreed to the foregoing procedures to facilitate transfers of interests in the Global Certificates among Participants in DTC, Euroclear and Cedel Bank, they are under no obligation to perform or to continue to perform such procedures, and such procedures may be discontinued at any time. None of the Company, the Transfer Agent or the Exchange Trustee nor any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Cedel Bank or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations. Exchange of Book-Entry Certificates for Certificated Securities A Global Certificate is exchangeable for definitive Certificates in registered certificated form ("Certificated Securities") if: (1) DTC: (a) notifies the Company that it is unwilling or unable to continue as depositary for the Global Certificate and the Company fails to appoint a successor depositary; or (b) has ceased to be a clearing agency registered under the Exchange Act and the Company fails to appoint a successor depositary; (2) the Company, at its option, notifies the Exchange Trustee in writing that it elects to cause the issuance of the Exchangeable Preferred Stock or Exchange Debentures, as applicable, in certificate form; or (3) there shall have occurred and be continuing (a) a Voting Rights Triggering Event with respect to the Exchangeable Preferred Stock or (b) a Default or Event of Default with respect to the Exchange Debentures. In addition, beneficial interests in a Global Certificate may be exchanged for Certificated Certificates upon request but only upon prior written notice given to the Exchange Trustee by or on behalf of DTC in accordance with the Exchange Indenture. In all cases, certificated securities delivered in exchange for any Global Certificate or beneficial interests therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures) and will bear the applicable restrictive legend referred to in "Notice to Investors," unless the Company determines otherwise in compliance with applicable law. 188

Exchange of Certificated Securities for Book-Entry Securities Certificates issued in certificated form may not be exchanged for beneficial interests in any Global Certificate unless the transferor first delivers to the Transfer Agent or the Exchange Trustee, as applicable, a written certificate (in the form provided in the Certificate of Designations or the Exchange Indenture) to the effect that such transfer will comply with the appropriate transfer restrictions applicable to such Certificate. Same Day Settlement and Payment The Certificate of Designation or the Exchange Indenture, as applicable, require that payments in respect of the Certificates represented by the Global Certificates (including Liquidation Preference, dividends, principal, premium, interest and Liquidated Damages) be made by wire transfer of immediately available funds to the accounts specified by the Global Certificate Holder. With respect to Certificated Securities, the Company will make all such payments by wire transfer of immediately available funds to the accounts specified by the Holders thereof or, if no such account is specified, by mailing a check to each such Holder's registered address. The Certificates represented by the Global Certificates are expected to be eligible to trade in the PORTAL market and to trade in the Depositary's Same-Day Funds Settlement System, and any permitted secondary market trading activity in such Certificates will, therefore, be required by the Depositary to be settled in immediately available funds. The Company expects that secondary trading in any certificated Certificates will also be settled in immediately available funds. Registration Rights and Liquidated Damages Holders of the New Preferred Stock are not entitled to any registration rights with respect to the New Preferred Stock. The Company and the Initial Purchasers entered into the Registration Rights Agreement for the benefit of the holders of Transfer Restricted Securities on the Closing Date. Pursuant to the Registration Rights Agreement, the Company agreed to file with the Commission the Exchange Offer Registration Statement on the appropriate form under the Securities Act with respect to the New Preferred Stock. The registration statement of which this Prospectus is a part constitutes the Exchange Offer Registration Statement. The Registration Rights Agreement provides that if (i) the Company is not required to file the Exchange Offer Registration Statement or permitted to consummate the Exchange Offer because the Exchange Offer is not permitted by applicable law or Commission policy or (ii) any Holder of Transfer Restricted Securities notifies the Company prior to the 20th day following consummation of the Exchange Offer that (A) it is prohibited by law or Commission policy from participating in the Exchange Offer or (B) that it may not resell the New Preferred Stock acquired by it in the Exchange Offer to the public without delivering a Prospectus and the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales or (C) that it is a broker-dealer and owns Preferred Stock acquired directly from the Company or an affiliate of the Company, the Company will file with the Commission a Shelf Registration Statement to cover resales of the Preferred Stock by the Holders thereof, subject to such Holders satisfying certain conditions relating to the provision of information in connection with the Shelf Registration Statement. The Company has agreed that it will use all commercially reasonable efforts to cause any such Shelf Registration Statement to be declared effective as promptly as possible by the Commission. For purposes of the foregoing, "Transfer Restricted Securities" means each Old Preferred Stock until (i) the date on which such Old Preferred Stock has been exchanged by a person other than a broker-dealer for a New Preferred Stock in the Exchange Offer, (ii) following the exchange by a broker-dealer in the Exchange Offer of an Old Preferred Stock for a New Preferred Stock, the date on which such New Preferred Stock is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the Prospectus contained in the Exchange Offer Registration Statement, (iii) the date on which such Old Preferred Stock has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or (iv) the date on which such Old Preferred Stock is distributed to the public pursuant to Rule 144 under the Act. The Registration Rights Agreement provides that (i) the Company will file an Exchange Offer Registration Statement with the Commission on or prior to 60 days after the Closing Date, (ii) the Company will use all 189

commercially reasonable efforts to have the Exchange Offer Registration Statement declared effective by the Commission on or prior to 150 days after the Closing Date, (iii) unless the Exchange Offer would not be permitted by applicable law or Commission policy, the Company will commence the Exchange Offer and use its best efforts to issue on or prior to 30 business days after the date on which the Exchange Offer Registration Statement was declared effective by the Commission, New Preferred Stock in exchange for all Old Preferred Stock tendered prior thereto in the Exchange Offer and (iv) if obligated to file the Shelf Registration Statement, the Company will use its best efforts to file the Shelf Registration Statement with the Commission on or prior to 45 days after such filing obligation arises and to cause the Shelf Registration to be declared effective by the Commission on or prior to 90 days after such obligation arises. If (a) the Company fails to file any of the Registration Statements required by the Registration Rights Agreement on or before the date specified for such filing, (b) any of such Registration Statements is not declared effective by the Commission on or prior to the date specified for such effectiveness (the "Effectiveness Target Date"), or (c) the Company fails to consummate the Exchange Offer within 30 business days of the Effectiveness Target Date with respect to the Exchange Offer Registration Statement, or (d) the Shelf Registration Statement or the Exchange Offer Registration Statement is declared effective but thereafter ceases to be effective or usable in connection with resales of Transfer Restricted Securities during the periods specified in the Registration Rights Agreement (each such event referred to in clauses (a) through (d) above a "Registration Default"), then the Company will pay Liquidated Damages to each Holder of Exchangeable Preferred Stock, with respect to the first 90-day period immediately following the occurrence of the first Registration Default in an amount equal to $.05 per week per $1,000 of the liquidation preference of the Exchangeable Preferred Stock held by such Holder. The amount of the Liquidated Damages will increase by an additional $.05 per week per $1,000 of the liquidation preference of the Exchangeable Preferred Stock with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum amount of Liquidated Damages for all Registration Defaults of $.50 per week per $1,000 of the liquidation preference of the Exchangeable Preferred Stock. All accrued Liquidated Damages will be paid by the Company on each interest payment date to the Holders of record on the immediately preceding record date by wire transfer of immediately available funds, in the case of the Holder of Global Preferred Stock, and to Holders of Certificated Securities by wire transfer to the accounts specified by them or by mailing checks to their registered addresses if no such accounts have been specified. Following the cure of all Registration Defaults, the accrual of Liquidated Damages will cease. 190

DESCRIPTION OF CAPITAL STOCK The following summary does not purport to be complete and is subject to the detailed provisions of, and qualified in its entirety by reference to, the Certificate of Incorporation, the Certificate of Designations, the By-laws, the Governance Agreement, the CTSH Shareholders Agreement and the Stockholders' Agreement, and to the applicable provisions of the Delaware General Corporation Law (the "DGCL"). General The authorized capital stock of the Company consists of 600,000,000 shares of Common Stock, par value $.01 per share (the "Common Stock"), 90,000,000 shares of Class A Common Stock, par value $.01 per share (the "Class A Common Stock"), and 10,000,000 shares of Preferred Stock, par value $.01 per share. There are 82,921,352 shares of Common Stock outstanding and 11,340,000 shares of Class A Common Stock outstanding. Common Stock Voting Rights Each share of Common Stock is entitled to one vote. The Common Stock votes together as a single class on all matters presented for a vote of the stockholders, except as provided under the DGCL. All the outstanding shares of Common Stock are held by directors, executive officers, other employees and affiliates of the Company or its subsidiaries. Dividends Each share of Common Stock is entitled to receive dividends if, as and when declared by the Board of Directors out of funds legally available therefor, subject to approval of certain holders of the Senior Convertible Preferred Stock. Liquidation Rights In the event of the dissolution of the Company, after satisfaction of amounts payable to creditors and distribution to the holders of outstanding Senior Convertible Preferred Stock, if any, of amounts to which they may be preferentially entitled, holders of Common Stock are entitled to share ratably in the assets available for distribution to the stockholders. Other Provisions There are no preemptive rights to subscribe for any additional securities which the Company may issue, and there are no redemption provisions or sinking fund provisions applicable to the Common Stock. All outstanding shares of Common Stock are legally issued, fully paid and nonassessable. Class A Common Stock Voting Rights Each share of Class A Common Stock is entitled to one vote for each such share on all matters presented to the stockholders, except with respect to the election of directors. The holders of the shares of Class A Common Stock vote, except as provided under the DGCL, together with the holders of the Common Stock and any other class or series of stock of the Company accorded such general voting rights, as a single class. So long as TdF is Qualified, holders of shares of Class A Common Stock voting as a separate class have the right to elect two directors to the Board of Directors of the Company; provided, however, that if TdF is not Qualified, so long as the ownership interest of the TdF Group is at least 5%, holders of Class A Common Stock voting as a separate class have the right to elect one director. 191

The holders of Class A Common Stock, subject to certain limitations described in "The Roll-Up--Governance Agreement--Governance Limitations", have a Veto over certain significant actions, described in "Governance--Veto Rights", taken by the Company. Convertibility Each share of Class A Common Stock is convertible, at the option of its record holder, into one share of Common Stock at any time. In the event of any transfer of any share of Class A Common Stock to any Person other than an Affiliate (as defined in Rule 12b-2 of the Exchange Act), such share of Class A Common Stock automatically converts, without any further action, into one share of Common Stock; provided, however, and subject to certain conditions described in the Certificate of Incorporation, that a holder of shares of Class A Common Stock may pledge such holder's shares to a financial institution pursuant to a bona fide pledge of such shares of Class A Common Stock as collateral security for any indebtedness or other obligation of any Person due to the pledgee or its nominee. Further, each share of Class A Common Stock automatically converts into one share of Common Stock on the first date on which the ownership interest of TdF Group is less than 5%. Other Provisions Pursuant to the Governance Agreement, so long as it remains Qualified, TdF has anti-dilutive rights in connection with maintaining a certain percentage of voting power in the Company and, accordingly, the Company may not, subject to certain exceptions relating primarily to compensation of directors and employees, issue, sell or transfer additional securities (except for the IPO) unless TdF is offered the right to purchase, at the same price, an amount such that it would maintain such percentage of voting power in the Company. All outstanding shares of Class A Common Stock are legally issued, fully paid and nonassessable. Preferred Stock Pursuant to the Certificate of Incorporation, the Company may issue up to 10,000,000 shares of Preferred Stock in one or more series. The Board of Directors has the authority, without any vote or action by the stockholders (other than any rights of TdF under the Governance Agreement), to create one or more series of Preferred Stock up to the limited of the Company's authorized but unissued shares of Preferred Stock and to fix the designations, preferences, rights, qualifications, limitations and restrictions thereof, including the voting rights, dividend rights, dividend rate, conversion rights, terms of redemption (including sinking fund provisions), redemption price or prices, liquidation preferences and the number of shares constituting any series. See "Risk Factors--Anti-Takeover Provisions". Senior Preferred Warrants In connection with the offering of the Senior Convertible Preferred Stock in August 1997 and October 1997, the Company issued warrants to purchase an aggregate of 1,314,990 shares of Common Stock at a price of $7.50 per share. Certificate of Incorporation and By-laws Stockholders' rights and related matters are governed by the DGCL, the Certificate of Incorporation and the By-laws. Certain provisions of the Certificate of Incorporation and By-laws, which are summarized below, may have the effect, either alone or in combination with each other, of discouraging or making more difficult a tender offer or takeover attempt that is opposed by the Company's Board of Directors but that a stockholder might consider to be in its best interest. Such provisions may also adversely affect prevailing market prices for the Common Stock. The Company believes that such provisions are necessary to enable the Company to develop its 192

business in a manner that will foster its long-term growth without disruption caused by the threat of a takeover not deemed by the Board of Directors to be in the best interests of the Company and its stockholders. Classified Board of Directors and Related Provisions The Certificate of Incorporation provides that the directors of the Company, other than those directors who may be elected by holders of any series of Preferred Stock or holders of the Class A Common Stock, initially are to be divided into three classes of directors, initially consisting of three, three and four directors. One class of directors, initially consisting of three directors, will be elected for a term expiring at the annual meeting of shareholders to be held in 1999, another class initially consisting of three directors will be elected for a term expiring at the annual meeting of stockholders to be held in 2000, and another class initially consisting of four directors shall be initially elected for a term expiring at the annual meeting of stockholders in 2001. The classified board provisions will prevent a party who acquires control of a majority of the outstanding Voting Stock of the Company from obtaining control of the Board of Directors until the second annual stockholders meeting following the date such party obtains the controlling interest. The provisions of the Certificate of Incorporation relating to the classified nature of the Company's Board of Directors may not be amended without the affirmative vote of the holders of at least 80% of the voting power of the Company's outstanding Voting Stock. "Voting Stock" is defined in the Certificate of Incorporation as the outstanding shares of capital stock of the Company entitled to vote in a general vote of stockholders of the Corporation as a single class with shares of Common Stock of the Company, which shares of capital stock include the shares of Class A Common Stock. No Stockholder Action by Written Consent; Special Meeting The Certificate of Incorporation prohibits stockholders (other than holders of Class A Common Stock with respect to matters upon which such holders are entitled to vote as a separate class) from taking action by written consent in lieu of an annual or special meeting and, thus, stockholders may only take action at an annual or special meeting called in accordance with the By-laws. The By-laws provide that special meetings of stockholders may only be called by the Secretary of the Company at the direction of the Board of Directors pursuant to a resolution adopted by the Board. These provisions could have the effect of delaying consideration of a stockholder proposal until the next annual meeting. The provisions would also prevent the holders of a majority of the voting power of the capital stock of the Company entitled to vote from unilaterally using the written consent procedure to take stockholder action. Advance Notice Requirements for Stockholder Proposals and Director Nominations The By-laws establish advance notice procedures with regard to stockholder proposals and the nomination, other than by or at the direction of the Board of Directors, of candidates for election as directors. These procedures provide that the notice of stockholder proposals and stockholder nominations for the election of directors at an annual meeting must be in writing and received by the Secretary no less than 90 days nor more than 120 days prior to the first anniversary of the preceding year's annual meeting; provided, however, that with respect to the annual meeting to be held in 1999, the anniversary date shall be deemed to be April 1, 1999; provided further that in the event that the date of the annual meeting is advanced by more than 30 days, or delayed by more than 90 days, from such anniversary date, notice by the stockholder to be timely must be delivered not earlier than the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public disclosure of the date of the annual meeting was made. The notice of nominations for the election of directors must set forth certain information with respect to the stockholder giving the notice and with respect to each nominee. By requiring advance notice of nominations by stockholders, the foregoing procedures will afford the Board of Directors an opportunity to consider the qualifications of the proposed nominees and, to the extent deemed 193

necessary or desirable by the Board of Directors, to inform stockholders about such qualifications. By requiring advance notice of other proposed business, such procedures will provide the Board of Directors with an opportunity to inform stockholders, prior to such meetings, of any business proposed to be conducted at such meetings, together with any recommendations as to the Board of Directors' position regarding action to be taken with respect to such business, so that stockholders can better decide whether to attend such a meeting or to grant a proxy regarding the disposition of any such business. Dilution The Certificate of Incorporation provides that the Board of Directors is authorized to create and issue, whether or not in connection with the issuance and sale of any of its stock or other securities or property, rights entitling the holders to purchase from the Company shares of stock or other securities of the Company or any of other corporation, recognizing that, under certain circumstances, the creation and issuance of such rights could have the effect of discouraging third parties from seeking, or impairing their right to seek, to acquire a significant portion of the outstanding securities of the Company, to engage in any transaction which might result in a change of control of the corporation or to enter into any agreement, arrangement or understanding with another party to accomplish the foregoing or for the purpose of acquiring, holding, voting or disposing of any securities of the Company. Indemnification The Certificate of Incorporation and By-laws provide that the Company shall indemnify each director or officer of the Company to the fullest extent permitted by law. Amendments The Certificate of Incorporation and By-laws provide that the Company may at any time and from time to time, amend, alter, change or repeal any provision contained in the Certificate of Incorporation or a Preferred Stock designation; provided, however, the affirmative vote of the holders of at least 80% of the voting power of the then outstanding Voting Stock, voting together as a single class, is required to amend, repeal or adopt any provision inconsistent with certain provisions of the Certificate of Incorporation, including the provisions referred to above relating to the classification of the Board of Directors, prohibiting stockholder action by written consent, and prohibiting the calling of special meetings by stockholders. The By-laws may be amended by either the holders of 80% of the voting power of the Voting Stock or by the majority of the Board; provided that the Board may alter, amend or repeal or adopt new By-laws in conflict with certain provisions thereof by a two-thirds vote of the entire Board. Rights Plan Rights The Board of Directors of the Company has declared a dividend of one right (the "Rights") for each outstanding share of Common Stock and each outstanding share of Class A Common Stock. The Rights will be issued to the holders of record of Common Stock and Class A Common Stock outstanding on the date of the consummation of the IPO (the "Issuance Date"), and with respect to Common Stock and Class A Common Stock issued thereafter until the Distribution Date (as defined below), and, in certain circumstances, with respect to Common Stock and Class A Common Stock issued after the Distribution Date. Each Right, when it becomes exercisable as described below, will entitle the registered holder to purchase from the Company one one-thousandth (1/1000th) of a share of Series A Participating Cumulative Preferred Stock (the "Preferred Shares") at a price of $110.00 per (1/1000th) of a share, subject to adjustment in certain circumstances (the "Purchase Price"). The description and terms of the Rights are set forth in a Rights Agreement (the "Rights Agreement") between the Company and the Rights Agent named therein. The Rights will not be exercisable until the Distribution Date and will expire on the tenth annual anniversary of the Rights Agreement (the "Expiration 194

Date"), unless earlier redeemed by the Company. Until a Right is exercised, the holder thereof, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends with respect to the Rights or the Preferred Shares relating thereto. Distribution Date Under the Rights Agreement, the Distribution Date is the earlier of (i) such time as the Company learns that a person or group (including any affiliate or associate of such person or group) has acquired, or has obtained the right to acquire, beneficial ownership of more than 15% of the outstanding voting securities of the Company (such person or group being an "Acquiring Person"), subject to the exceptions relating to the TDF Group and the Berkshire Group described in the paragraph below, unless provisions preventing accidental triggering of the distribution of the Rights apply, and (ii) the close of business on such date, if any, as may be designated by the Board of Directors following the commencement of, or first public disclosure of an intent to commence, a tender or exchange offer for more than 15% or more of the outstanding shares of Voting Securities. Each member of the TdF Group will not otherwise be considered an Acquiring Person if (a) during the first five years following the adoption of the Rights Agreement, the aggregate ownership interest of the TdF Group does not exceed 25% (or 30% if the Board so elects) of the outstanding Voting Securities or (b) thereafter, the aggregate ownership interest of the TdF Group does not exceed the lesser of (i) 25% or 30%, as applicable, of the Voting Securities then outstanding and (ii) the greater of (x) the aggregate interest of the TdF Group as of the fifth anniversary of the Rights Agreement and (y) 15% of the then outstanding Voting Securities. Each member of the Berkshire Group will not otherwise be deemed an Acquiring Person if the aggregate ownership interest of the Berkshire Group does not exceed the greater of (a) the aggregate ownership interest of the Berkshire Group upon the execution of the Rights Agreement, reduced by an amount equal to any disposition of Voting Securities following the date the Rights Agreement is executed and (b) 15% of the outstanding Voting Securities. Triggering Event and Effect of Triggering Event At such time as there is an Acquiring Person, the Rights will entitle each holder (other than such Acquiring Person) of a Right to purchase, at the Purchase Price, that number of one-thousandths (1/1000ths) of a Preferred Share equivalent to the number of shares of Common Stock that at the time of such event would have a market value of twice the Purchase Price. In the event the Company is acquired in a merger or other business combination by an Acquiring Person or an affiliate or associate of an Acquiring Person that is a publicly traded corporation or 50% or more of the Company's assets or assets representing 50% or more of the Company's revenues or cash flow are sold, leased, exchanged or otherwise transferred (in one or more transactions) to an Acquiring Person or an affiliate or associate of an Acquiring Person that is a publicly traded corporation, each Right will entitle its holder (other than Rights beneficially owned by such Acquiring Person or its affiliates or associates) to purchase, for the Purchase Price, that number of common shares of such corporation which at the time of the transaction would have a market value or, in certain circumstances, book value of twice the Purchase Price. In the event the Company is acquired in a merger or other business combination by an Acquiring Person or an affiliate or associate of an Acquiring Person that is not a publicly traded entity or 50% or more of the Company's assets or assets representing 50% or more of the Company's revenues or cash flow are sold, leased, exchanged or otherwise transferred (in one or more transactions) to an Acquiring Person or affiliate or associate of an Acquiring Person that is not a publicly traded entity, each right will entitle its holder (subject to the next paragraph) to purchase, for the Purchase Price, at such holder's option, (i) that number of shares of the surviving corporation in the transaction with such entity (which surviving corporation could be the Company) which at the time of the transaction would have a book value of twice the Purchase Price, (ii) that number of shares of the ultimate parent of or entity controlling such surviving corporation which at the time of the transaction would have a book value of twice the Purchase Price or (iii) if such entity has an affiliate which has publicly traded 195

common shares, that number of common shares of such affiliate which at the time of the transaction would have market value of twice the Purchase Price. Any Rights that are at any time beneficially owned by an Acquiring Person (or any affiliate or associate of an Acquiring Person) will be null and void and nontransferable and any holder of any such right (including any purported transferee or subsequent holder) will be unable to exercise or transfer any such Right. Redemption At any time prior to the earlier of (i) such time as a person or group becomes an Acquiring Person and (ii) the Expiration Date, the Board of Directors may redeem the Rights in whole, but not in part, at a price (in cash or Common Stock or other securities of the Company deemed by the Board of Directors to be at least equivalent in value) of $.01 per Right (which amount shall be subject to adjustment as provided in the Rights Agreement) (the "Redemption Price"). Immediately upon the action of the Board of Directors ordering the redemption of the Rights, and without any further action and without any notice, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price. In addition, at any time after there is an Acquiring Person, the Board of Directors may elect to exchange each Right for consideration per Right consisting of one-half of the securities that would be issuable at such time upon exercise of one Right pursuant to the terms of the Rights Agreement. Amendment At any time prior to the Distribution Date, the Company may, without the approval of any holder of any Rights, supplement or amend any provision of the Rights Agreement (including, without limitation, the date on which the Expiration Date or Distribution Date shall occur, the definition of Acquiring Person, the time during which the Rights may be redeemed or the terms of the Preferred Shares), except that no supplement or amendment shall be made which reduces the Redemption Price (other than pursuant to certain adjustments therein). Certain Effects of the Rights Plan The Rights plan is designed to protect stockholders of the Company in the event of unsolicited offers to acquire the Company and other coercive takeover tactics which, in the opinion of the Board of Directors, could impair its ability to represent stockholder interests. The provisions of the Rights Plan may render an unsolicited takeover of the Company more difficult or less likely to occur or might prevent such a takeover, even though such takeover may offer the Company's stockholders the opportunity to sell their stock at a price above the prevailing market rate and may be favored by a majority of the stockholders of the Company. Section 203 of the Delaware General Corporation Law Section 203 of the DGCL prohibits certain transactions between a Delaware corporation and an "interested stockholder", which is defined as a person who, together with any affiliates and/or associates of such person, beneficially owns, directly or indirectly, 15% or more of the outstanding voting shares of a Delaware corporation. This provision prohibits certain business combinations (defined broadly to include mergers, consolidations, sales or other dispositions of assets having an aggregate value of 10% or more of the consolidated assets of the corporation, and certain transactions that would increase the interested stockholder's proportionate share ownership in the corporation) between an interested stockholder and a corporation for a period of three years after the date the interested stockholder acquired its stock, unless: (i) the business combination is approved by the corporation's Board of Directors prior to the date the interested stockholder acquired shares; (ii) the interested stockholder acquired at least 85% of the voting stock of the corporation in the transaction in which it became an interested stockholder; or (iii) the business combination is approved by a majority of the Board of Directors and by the affirmative vote of two-thirds of the outstanding voting stock owned by disinterested stockholders at an annual or special meeting. A Delaware corporation, pursuant to a provision in its certificate of incorporation or 196

by-laws, may elect not to be governed by Section 203 of the DGCL. The Certificate of Incorporation does not exclude the Company from the restrictions imposed by Section 203 of the DGCL and, as a result, the Company will be subject to its provisions upon consummation of the IPO. Under certain circumstances, Section 203 of the DGCL makes it more difficult for a person who could be an "interested stockholder" to effect various business combinations with a corporation for a three-year period, although the stockholders may elect to exclude a corporation from the restrictions imposed thereunder. The Certificate of Incorporation of the Company does not exclude the Company from the restrictions imposed under Section 203 of the DGCL. It is anticipated that the provisions of Section 203 of the DGCL may encourage companies interested in acquiring the Company to negotiate in advance with the Board of Directors, since the stockholder approval requirement would be avoided if a majority of the directors then in office approves, prior to the date on which a stockholder becomes an interested stockholder, either the business combination or the transaction which results in the stockholder becoming an interested stockholder. Limitations of Directors' Liability The Certificate of Incorporation provides that no director of the Company will be personally liable to the Company or its stockholders for monetary damages for breach of fiduciary duty as a director except for liability: (1) for any breach of the director's duty of loyalty to the Company or its stockholders, (2) for acts of omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL, or (4) for any transaction from which the director derived an improper personal benefit. The effect of these provisions will be to eliminate the rights of the Company and its stockholders (through stockholders' derivatives suits on behalf of the Company) to recover monetary damages against a director for breach of fiduciary duty as a director (including breaches resulting from grossly negligent behavior), except in the situations described above. These provisions will not limit the liability of directors under federal securities laws and will not affect the availability of equitable remedies such as an injunction or rescission based upon a director's breach of his duty of care.

DESCRIPTION OF CERTAIN INDEBTEDNESS Senior Credit Facility Pursuant to the Amended and Restated Loan Agreement dated as of July 10, 1998, two wholly owned subsidiaries of CCIC, CCI and Crown Castle International Corp. de Puerto Rico ("CCIC(PR)") (collectively, the "Borrowers"), have entered into the Senior Credit Facility with a group of banks and other financial institutions led by Key Corporate Capital Inc. ("KeyCorp") and PNC Bank, National Association, as arrangers and agents. The following summary of certain provisions of the Senior Credit Facility does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the provisions of the Senior Credit Facility. The Senior Credit Facility provides for revolving credit loans in an aggregate principal amount not to exceed $100.0 million, for working capital needs, acquisitions and general corporate purposes. The Senior Credit Facility includes a $5.0 million sublimit available for the issuance of letters of credit. As of November 1, 1998, the Company had no significant unused borrowing availability under the Senior Credit Facility. The loan commitment under the Senior Credit Facility reduces by $5.0 million commencing March 31, 2001 and by $5.0 million each calendar quarter thereafter until December 31, 2004, when the Senior Credit Facility matures. In addition, the Senior Credit Facility provides for mandatory reduction of the loan commitment and mandatory prepayment with the (i) net proceeds of certain asset sales, (ii) net proceeds of certain required capital contributions to CCI by CCIC relating to the proceeds from the sale of equity, convertible or debt securities, subject to certain exceptions, (iii) net proceeds of any unused insurance proceeds and (iv) a percentage of the excess cash flow of the Borrowers, commencing with the calendar year ending December 31, 2000. The Borrowers' obligations under the Senior Credit Facility are guaranteed by each direct and indirect majority owned subsidiary of CCI and are also secured by (i) a pledge by the Borrowers of all of the outstanding capital stock of each of their respective direct subsidiaries and (ii) a perfected first priority security interest in substantially all of the personal property of the Borrowers and their subsidiaries. In addition, the Senior Credit Facility is guaranteed on a limited recourse basis by CCIC, limited in recourse to the collateral pledged by CCIC (the capital stock of CCI). The capital stock of CTSH will not be pledged to secure the Senior Credit Facility. The loans under the Senior Credit Facility will bear interest, at the Borrowers' option, at either (A) a "base rate" equal to KeyCorp's prime lending rate plus an applicable spread ranging from 0% to 1.5% (determined based on a leverage ratio) or (B) a "LIBOR rate" plus an applicable spread ranging from 1.0% to 3.25% (determined based on a leverage ratio). Following the occurrence and during the continuance of an event of default under the Senior Credit Facility, the loans will bear interest at the "base rate" plus 3.5%. The Senior Credit Facility contains a number of covenants that, among other things, restrict the ability of the Borrowers and their respective subsidiaries to dispose of assets, incur additional indebtedness, incur guaranty obligations, repay subordinated indebtedness except in accordance with the subordination provisions, pay dividends or make capital distributions, create liens on assets, enter into leases, make investments, make acquisitions, engage in mergers or consolidations, make capital expenditures, engage in certain transactions with subsidiaries and affiliates and otherwise restrict corporate activities. In addition, the Senior Credit Facility will require compliance with certain financial covenants, including requiring the Borrowers and their respective subsidiaries to maintain a maximum ratio of indebtedness to operating cash flow, a minimum ratio of operating cash flow to fixed charges, a minimum ratio of operating cash flow to projected debt service and a minimum ratio of operating cash flow to interest expense. CCIC does not expect that such covenants will materially impact the ability of the Borrowers and their respective subsidiaries to operate their respective businesses. Pursuant to the terms of the Senior Credit Facility, CCI is entitled to pay dividends or make distributions to CCIC in order to permit CCIC to pay its out-of-pocket costs for corporate development and overhead and to pay cash interest on certain indebtedness of CCIC (including the Notes); provided that the amount of such dividends or distributions does not exceed (i) $6.0 million in any year ending on or prior to October 31, 2002 or (ii) $33.0 198

million in any year thereafter. The Senior Credit Facility also allows CCI to pay dividends or distribute cash to CCIC to the extent required to pay taxes allocable to the Borrowers and their respective subsidiaries. All of the above-mentioned dividends or distributions, however, including dividends or distributions that are intended to pay interest on the Notes, may not be made by CCI so long as any default or event of default exists under the Senior Credit Facility. The Senior Credit Facility contains customary events of default, including the failure to pay principal when due or any interest or other amount that becomes due within two days after the due date thereof, any representation or warranty being made by the Borrowers that is incorrect in any material respect on or as of the date made, a default in the performance of any negative covenants or a default in the performance of certain other covenants or agreements for a period of thirty days, default in certain other indebtedness, certain insolvency events and certain change of control events. In addition, a default under the Notes Indenture will result in a default under the Senior Credit Facility. CTI Credit Facility Pursuant to the Loan Amendment Agreement dated May 21, 1997 (the "CTI Credit Facility"), among CTI, as borrower, CTSH, as guarantor, Credit Suisse First Boston, as arranger and agent ("CSFB"), and J.P. Morgan Securities Ltd., as co-arranger ("JPM"), CTI's (Pounds)162.5 million term and revolving loan facilities (the "Old Facilities") were amended to a (Pounds)64.0 million revolving loan facility. The following summary of certain provisions of the CTI Credit Facility does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the provisions of the CTI Credit Facility. The CTI Credit Facility provides for revolving credit loans in an aggregate principal amount not to exceed (Pounds)64.0 million to finance capital expenditures in respect of digital terrestrial television with up to (Pounds)46.5 million of such amount available for working capital needs and for general corporate purposes. As of September 30, 1998, CTI had unused borrowing availability under the CTI Credit Facility of approximately (Pounds)30.0 million ($51.0 million). The loan commitment under the CTI Credit Facility will be automatically reduced to zero in three equal semi-annual installments commencing on May 31, 2001 and ending on May 31, 2002, when the CTI Credit Facility matures. In addition, the CTI Credit Facility provides for mandatory cancellation of all or part of the loan commitment and mandatory prepayment (i) with an amount equal to the net proceeds of certain asset sales and (ii) upon the consummation of an initial public offering or the listing on any stock exchange of the shares of CTI, CTSH or CCIC. CTI's and CTSH's obligations under the CTI Credit Facility are secured by fixed and floating charges over all of their respective assets. The loans under the CTI Credit Facility will bear interest at a "LIBOR rate" plus 0.85% and a spread related to the lenders' cost of making the CTI Credit Facility available to CTI. The CTI Credit Facility contains a number of covenants that, among other things, restrict the ability of CTI to dispose of assets, incur additional indebtedness, incur guaranty obligations, repay subordinated indebtedness except in accordance with the subordination provisions, pay dividends or make capital distributions, create liens on assets, make investments, make acquisitions, engage in certain transactions with subsidiaries and affiliates and otherwise restrict corporate activities. In addition, the CTI Credit Facility will require compliance with certain financial covenants, including requiring CTI to maintain a maximum ratio of indebtedness to EBITDA, a minimum ratio of EBITDA to interest expense, and a minimum tangible net worth. CCIC does not expect that such covenants will materially impact the ability of CTI to operate its business. The CTI Credit Facility contains customary events of default, including the failure to pay principal or any interest or any other amount that becomes due within three business days after the due date thereof, any representation or warranty being made by CTI that is untrue or misleading on the date made, a default in the performance of any of its covenants under the CTI Credit Facility (unless, if such default is capable of remedy, 199

such default is cured within 14 days of CTI becoming aware of such default), default in certain other indebtedness, certain insolvency events and certain change of control events. On July 17, 1998, the lenders (acting through Credit Suisse First Boston, as agent) under the CTI Credit Facility waived a provision in the CTI Credit Facility that would have required the repayment of the CTI Credit Facility concurrently with the listing of the Company's Common Stock. The Notes On November 20, 1997, the Company privately placed $251.0 million principal amount at maturity ($150,010,150 initial accreted value) of its 10 5/8% Senior Discount Notes due 2007 (the "Notes"). The following is a summary of certain terms of the Notes and is qualified in its entirety by reference to the Notes Indenture (the "Notes Indenture") relating to the Notes. A copy of the Notes Indenture has been filed with the Registration Statement of which this Prospectus forms a part. The Notes are unsecured senior obligations of the Company, and will rank pari passu in right of payment with all existing and future senior indebtedness of the Company and will be senior to future subordinated indebtedness of the Company. The Notes mature on November 15, 2007. The Notes will accrete in value until November 15, 2002. Thereafter, cash interest will accrue on the Notes at the rate of 10.625% per annum and will be payable semi- annually, commencing on May 15, 2003. Except as stated below, the notes are not redeemable prior to November 15, 2002. Thereafter, the Notes are redeemable at the option of the Company, in whole or in part, at any time or from time to time, at a premium which is at a fixed percentage that declines to par on or after November 15, 2005, in each case together with accrued and unpaid interest, if any, to the date of redemption. In the event the Company consummates a public equity offering or certain strategic equity investments prior to November 15, 2000, the Company may, at its option, use all or a portion of the proceeds from such offering to redeem up to 35% of the original aggregate principal amount at maturity of the Notes at a redemption price equal to 110.625% of the accreted value of the Notes to be redeemed, plus accrued and unpaid interest, if any, thereon to the redemption date, provided at least 65% of the original aggregate principal amount at maturity of the Notes remains outstanding after each such redemption. Upon the occurrence of a Change of Control (as defined in the Notes Indenture), each holder of Notes has the right to require the Company to purchase all or a portion of such holder's Notes at a price equal to 101% of the aggregate principal amount thereof, together with accrued and unpaid interest to the date of purchase. The Notes Indenture contains certain covenants, including covenants that limit (i) indebtedness, (ii) restricted payments, (iii) distributions from restricted subsidiaries, (iv) transactions with affiliates, (v) sales of assets and subsidiary stock (including sale and leaseback transactions), (vi) dividend and other payment restrictions affecting restricted subsidiaries, and (vii) mergers or consolidations. The CTI Bonds On May 21, 1997, a subsidiary of CTSH issued (Pounds)125.0 million aggregate principal amount of its 9% Guaranteed Bonds due 2007 (the "CTI Bonds"). The CTI Bonds are listed on the Luxembourg Stock Exchange. The following is a summary of certain terms of the Bonds and is qualified in its entirety by reference to the trust deed dated May 21, 1997 (the "Trust Deed") relating to the Bonds. A copy of the Trust Deed has been filed with the Registration Statement of which this Prospectus forms a part. The Bonds constitute direct, general and unconditional guaranteed obligations of the subsidiary of CTSH and rank pari passu with all other present and future unsecured and unsubordinated obligations of such subsidiary. The CTI Bonds are guaranteed jointly and severally by CTI and CTSH. The CTI Bonds will mature on March 30, 2007. Interest on the Bonds is payable annually in arrears on March 30 in each year, the first payment having been made on March 30, 1998. 200

The CTI Bonds may be redeemed at the option of the Company in whole or in part, at any time or from time to time, at the greater of their principal and such price as will provide a gross redemption yield 0.5% per annum above the gross redemption yield of the benchmark gilt plus, in either case, accrued and unpaid interest. Upon the occurrence of a Put Event (as defined in the Trust Deed), each holder of CTI Bonds has the right to require such subsidiary to purchase all or a portion of such holder's CTI Bonds at a price equal to 101% of the aggregate principal amount thereof, together with accrued and unpaid interest to the date of purchase. The Trust Deed contains certain covenants, including covenants that limit (i) indebtedness, (ii) restricted payments, (iii) distributions from restricted subsidiaries, (iv) transactions with affiliates, (v) sales of assets and subsidiary stock, (vi) dividend and other payment restrictions affecting restricted subsidiaries, and (vii) mergers or consolidations. Proposed JV Credit Facility Key Corporate Capital Inc. ("KeyCorp") has committed, subject to formation of the joint venture and certain other conditions, to provide the Proposed JV with a revolving credit facility not to exceed $250.0 million. The following summary of certain provisions of the proposed loan facility (the "Proposed JV Credit Facility") does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the provisions of the Proposed JV Credit Facility. The Proposed JV Credit Facility provides for revolving credit loans in an aggregate principal amount not to exceed $250.0 million, $180.0 million of which is expected to be drawn in connection with the formation of the Proposed JV, and the balance of which will be used for acquisition and construction of tower facilities, capital expenditures, working capital needs and general corporate purposes. The borrowing base until September 30, 2001, is based on a multiple of test operating cash flow. On September 30, 2001 (the "Conversion Date"), the borrowing base test will be eliminated and the amount of the facility will be decreased to the borrowing base as of that date. The Proposed JV Credit Facility includes a $25.0 million sublimit available for the issuance of letters of credit. The amount of the facility after the Conversion Date will be reduced on a quarterly basis until March 31, 2006, when the Proposed JV Credit Facility matures. The annual percentage reduction in this loan commitment is 3.0% in 2001 (two quarters), 7.5% in 2002, 22.5% in 2003, 26.0% in 2004, 32.0% in 2005 and 9.0% in 2006 (one quarter). In addition, the Proposed JV Credit Facility provides for mandatory reduction of the loan commitment and mandatory prepayment with the (1) net proceeds of certain asset sales, (2) 50% of capital contributions to Holdco subject to certain significant exceptions including capital expenditures pursuant to the Build-to-Suit Agreement, (3) net proceeds of any unused insurance proceeds and (4) a percentage of the excess cash flow of the Proposed JV, commencing with the calendar year ending December 31, 2001. The Proposed JV's obligations under the Proposed JV Credit Facility are secured by (1) a pledge of the membership interest in the Proposed JV and (2) a perfected first priority security interest in the Proposed JV's interest in tenant leases including the Global Lease. The Proposed JV Credit Facility contractually permits the Proposed JV to pay maintenance, operating, ground lease and other expenses and costs relating to the tower facilities out of the tower rentals whether or not an event of default has occurred. The loans under the Proposed JV Credit Facility will bear interest, at the Proposed JV's option, at either (A) a "base rate" equal to KeyCorp's prime lending rate plus an applicable spread ranging from 0% to 1.25% (determined based on a leverage ratio) or (B) a "LIBOR rate" plus an applicable spread ranging from 1.0% to 2.875% (determined based on a leverage ratio). The Proposed JV must hedge approximately 50% of its variable interest rate obligations for a period of two years. Following the occurrence of and during the continuance of an event of default under the Proposed JV Credit Facility, the loans will bear interest at the "base rate" plus 4.875%. 201

The Proposed JV Credit Facility will contain a number of covenants that, among other things, restrict the ability of the Proposed JV to dispose of assets, incur additional indebtedness, incur guaranty obligations, repay subordinated indebtedness except in accordance with the subordination provisions, pay dividends or make capital distributions, create liens on assets, enter into leases, make investments, make acquisitions, engage in mergers or consolidations, make capital expenditures, engage in certain transactions with subsidiaries and affiliates and otherwise restrict company activities. In addition, the Proposed JV Credit Facility will require compliance with certain financial covenants, including requiring the Proposed JV to maintain a minimum ratio of operating cash flow to indebtedness, a minimum ratio of operating cash flow to fixed charges, a minimum ratio of operating cash flow to projected debt service and a minimum ratio of operating cash flow to interest expense. The Proposed JV does not expect that such covenants will materially impact its ability to operate its business. The Proposed JV Credit Facility contains customary events of default, including the failure to pay principal when due or any interest or other amount that becomes due within two days after the due date thereof, any representation or warranty being made by the Proposed JV that is incorrect in any material respect on or as of the date made, a default in the performance of any negative covenants or a default in the performance of certain other covenants or agreements (including the Formation Agreement) for a period of days, default in certain other indebtedness, certain insolvency events and certain change of control events. During the first two years of the Proposed JV Credit Facility, capital contributions can cure an operating cash flow default and certain other covenant and agreement defaults. 202

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS The following discussion is a summary of certain U.S. federal income tax consequences of the Exchange Offer to holders of Old Preferred Stock, but does not purport to be a complete analysis of all potential tax effects. The summary set forth below is based upon the Internal Revenue Code of 1986, as amended (the "Code"), regulations of the Treasury Department, administrative rulings and pronouncements of the Internal Revenue Service and judicial decisions, all of which are subject to change, possibly with retroactive effect. This summary does not purport to address all the U.S. federal income tax consequences that may be applicable to particular holders, including dealers in securities, financial institutions, insurance companies and tax- exempt organizations. In addition, this summary does not consider the effect of any foreign, state, local, gift, estate or other tax laws that may be applicable to a particular holder. This summary applies only to a holder that acquired Old Preferred Stock at original issue for cash and holds Old Preferred Stock as a "capital asset" within the meaning of Section 1221 of the Code. Holders of Old Preferred Stock considering the Exchange Offer should consult their own tax advisors concerning the U.S. federal income tax consequences in light of their particular situations as well as any consequences arising under the laws of any other taxing jurisdiction. An exchange of Old Preferred Stock for New Preferred Stock pursuant to the Exchange Offer will not be treated as an exchange or other taxable event for U.S. federal income tax purposes. Accordingly, holders of Old Preferred Stock who exchange their Old Preferred Stock for New Preferred Stock will not recognize income, gain or loss for U.S. federal income tax purposes and any such holder will have the same adjusted tax basis and holding period in the New Preferred Stock as it had in the Old Preferred Stock immediately before the exchange. THE FOREGOING DISCUSSION OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS DOES NOT CONSIDER THE FACTS AND CIRCUMSTANCES OF ANY PARTICULAR HOLDER'S SITUATION OR STATUS. ACCORDINGLY, EACH HOLDER OF OLD PREFERRED STOCK SHOULD CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES OF THE EXCHANGE OFFER TO IT, INCLUDING THOSE UNDER STATE, FOREIGN AND OTHER TAX LAWS. PLAN OF DISTRIBUTION Each broker-dealer that receives New Preferred Stock for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Preferred Stock. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of New Preferred Stock received in exchange for Old Preferred Stock where such Old Preferred Stock were acquired as a result of market-making activities or other trading activities. The Company has agreed that for a period of 180 days after the Expiration Date, it will make available a prospectus meeting the requirements of the Preferred Stock Act to any broker-dealer for use in connection with any such resale. In addition, until , all dealers effecting transactions in the New Preferred Stock may be required to deliver a prospectus. The Company will not receive any proceeds from any sale of New Preferred Stock by broker-dealers. New Preferred Stock received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the New Preferred Stock or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such New Preferred Stock. Any broker-dealer that resells New Preferred Stock that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such New Preferred Stock may be deemed to be an "underwriter" within the meaning of the Preferred Stock Act and any profit on any such resale of New Preferred Stock and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Preferred Stock Act. The Letter of Transmittal states that 203

by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Preferred Stock Act.

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. General The information contained in the following notes to the consolidated financial statements is condensed from that which would appear in the annual consolidated financial statements; accordingly, the consolidated financial statements included herein should be reviewed in conjunction with the consolidated financial statements for the fiscal year ended December 31, 1997, and related notes thereto, of Crown Castle International Corp. included elsewhere herein. All references to the "Company" include Crown Castle International Corp. and its subsidiary companies unless otherwise indicated or the context indicates otherwise. The consolidated financial statements included herein are unaudited; however, they include all adjustments (consisting only of normal recurring adjustments) which, in the opinion of management, are necessary to present fairly the consolidated financial position of the Company at September 30, 1998, the consolidated results of operations for the three and nine months ended September 30, 1997 and 1998 and consolidated cash flows for the nine months ended September 30, 1997 and 1998. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the entire year. Recent Accounting Pronouncements In February 1997, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards No. 128, Earnings per Share ("SFAS 128"). SFAS 128 establishes new standards for computing and presenting earnings per share ("EPS") amounts for companies with publicly held common stock or potential common stock. The new standards require the presentation of both basic and diluted EPS amounts for companies with complex capital structures. Basic EPS is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period, and excludes the effect of potentially dilutive securities (such as options, warrants and convertible securities) which are convertible into common stock. Dilutive EPS reflects the potential dilution from such convertible securities. SFAS 128 is effective for periods ending after December 15, 1997. The Company has adopted the requirements of SFAS 128 in its financial statements for the year ended December 31, 1997. In June 1997, the FASB issued Statement of Financial Accounting Standards No. 130, Reporting Comprehensive Income ("SFAS 130"). SFAS 130 establishes standards for the reporting and display of comprehensive income in a company's financial statements. Comprehensive income includes all changes in a company's equity accounts (including net income or loss) except investments by, or distributions to, the company's owners. Items which are components of comprehensive income (other than net income or loss) include foreign currency translation adjustments, minimum pension liability adjustments and unrealized gains and losses on certain investments in debt and equity securities. The components of comprehensive income must be reported in a financial statement that is displayed with the same prominence as other financial statements. SFAS 130 is effective for fiscal years beginning after December 15, 1997. The Company has adopted the requirements of SFAS 130 in its financial statements for the three months ended March 31, 1998. In June 1997, the FASB issued Statement of Financial Accounting Standards No. 131, Disclosures about Segments of an Enterprise and Related Information ("SFAS 131"). SFAS 131 establishes standards for the way that public companies report, in their annual financial statements, certain information about their operating segments, their products and services, the geographic areas in which they operate and their major customers. SFAS 131 also requires that certain information about operating segments be reported in interim financial statements. SFAS 131 is effective for periods beginning after December 15, 1997. The Company will adopt the requirements of SFAS 131 in its financial statements for the year ending December 31, 1998. F-6

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) In April 1998, the Accounting Standards Executive Committee of the American Institute of Certified Public Accountants issued Statement of Position 98-5, Reporting on the Costs of Start-Up Activities ("SOP 98-5"). SOP 98-5 requires that costs of start-up activities be charged to expense as incurred and broadly defines such costs. The Company has deferred certain costs incurred in connection with potential business initiatives and new geographic markets, and SOP 98-5 will require that such deferred costs be charged to results of operations upon its adoption. SOP 98-5 is effective for fiscal years beginning after December 15, 1998. The Company will adopt the requirements of SOP 98-5 as of January 1, 1999. The cumulative effect of the change in accounting principle for the adoption of SOP 98-5 will result in a charge to results of operations in the Company's financial statements for the three months ended March 31, 1999; it is currently estimated that such charge will amount to approximately $2,300,000. 2. Acquisitions On May 12, 1997, the Company acquired all of the common stock of TEA Group Incorporated and TeleStructures, Inc. (collectively, "TEA"). On August 15, 1997, the Company acquired (i) substantially all of the assets, net of outstanding liabilities, of Crown Communications ("CCM") and (ii) all of the outstanding common stock of Crown Network Systems, Inc. ("CNS") and Crown Mobile Systems, Inc. ("CMS") (collectively, "Crown"). These business acquisitions were accounted for using the purchase method. Results of operations and cash flows of the acquired businesses are included in the consolidated financial statements for the periods subsequent to the respective dates of acquisition. On April 24, 1998, the Company entered into a share exchange agreement with certain shareholders of Castle Transmission Services (Holdings) Ltd ("CTI") pursuant to which certain of CTI's shareholders agreed to exchange their shares of CTI for shares of the Company. On August 18, 1998, the exchange was consummated and the Company's ownership of CTI increased from approximately 34.3% to 80%. The Company issued 20,867,700 shares of its Common Stock and 11,340,000 shares of its Class A Common Stock, with such shares valued at an aggregate of $418,700,000 (based on the price per share to the public in the Company's initial public offering as discussed in Note 4). The Company recognized goodwill of $343,898,000 in connection with this transaction, which was accounted for as an acquisition using the purchase method. CTI's results of operations and cash flows are included in the consolidated financial statements for the period subsequent to the date the exchange was consummated. The following unaudited pro forma summary presents consolidated results of operations for the Company as if (i) the TEA and Crown acquisitions had been consummated as of January 1, 1997 and (ii) the share exchange with CTI's shareholders had been consummated as of January 1 for both 1997 and 1998. Appropriate adjustments have been reflected for depreciation and amortization, interest expense, amortization of deferred financing costs, income taxes and certain nonrecurring income and expenses recorded by the Company in connection with the investment in CTI in 1997. The pro forma information does not necessarily reflect the actual results that would have been achieved, not is it necessarily indicative of future consolidated results for the Company.

Furthermore, the Company's measure of the following information may not be comparable to similarly titled measures of other companies. Upon consummation of the share exchange with CTI's shareholders (see Note 2), which increased the Company's ownership interest in CTI to 80%, the Company designated CTI as an Unrestricted Subsidiary. In addition, the net proceeds from the Company's initial public offering of common stock (see Note 4) were placed into a newly formed subsidiary that was also designated as an Unrestricted Subsidiary. Prior to these transactions, the Company did not have any Unrestricted Subsidiaries. Summarized financial information for (i) the Company and its Restricted Subsidiaries and (ii) the Company's Unrestricted Subsidiaries is as follows: September 30, 1998 -------------------------------------- Company and Restricted Unrestricted Consolidated Subsidiaries Subsidiaries Total ------------ ------------ ------------ (In thousands of dollars) Cash and cash equivalents........... $ 34,116 $ 167,233 $ 201,349 Other current assets................ 16,051 26,540 42,591 Property and equipment, net......... 142,211 402,275 544,486 Goodwill and other intangible assets, net........................ 146,115 417,591 563,706 Other assets, net................... 15,600 2,207 17,807 -------- ---------- ---------- $354,093 $1,015,846 $1,369,939 ======== ========== ========== Current liabilities................. $ 11,183 $ 66,166 $ 77,349 Long-term debt...................... 232,803 261,521 494,324 Other liabilities................... 684 3,936 4,620 Minority interests.................. -- 38,529 38,529 Stockholders' equity................ 109,423 645,694 755,117 -------- ---------- ---------- $354,093 $1,015,846 $1,369,939 ======== ========== ========== F-8

Stockholders' Equity On August 18, 1998, the Company consummated its initial public offering of common stock at a price to the public of $13 per share (the "IPO"). The Company sold 12,320,000 shares of its common stock and received proceeds of $151,043,000 (after underwriting discounts of $9,117,000 but before other expenses of the IPO, which are expected to total approximately $3,800,000). The net proceeds from the IPO are currently invested in short-term investments. In anticipation of the IPO, the Company (i) amended and restated the 1995 Stock Option Plan to, among other things, authorize the issuance of up to 18,000,000 shares of common stock pursuant to awards made thereunder and (ii) approved an amendment to its certificate of incorporation to increase the number of authorized F-9

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) shares of common and preferred stock to 690,000,000 shares and 10,000,000 shares, respectively, and to effect a five-for-one stock split for the shares of common stock then outstanding. The effect of the stock split has been presented retroactively in the Company's consolidated financial statements for all periods presented. During the period from April 24, 1998 through July 15, 1998, the Company granted options to employees and executives for the purchase of 3,236,980 shares of its common stock at an exercise price of $7.50 per share. Of such options, options for 1,810,730 shares vested upon consummation of the IPO and the remaining options for 1,426,250 shares will vest at 20% per year over five years, beginning one year from the date of grant. In addition, the Company has assigned its right to repurchase shares of its common stock from a stockholder (at a price of $6.26 per share) to two individuals (including a newly-elected director) with respect to 100,000 of such shares. Since the granting of these options and the assignment of these rights to repurchase shares occurred subsequent to the date of the share exchange agreement with CTI's shareholders and at prices substantially below the price to the public in the IPO, the Company has recorded a non-cash compensation charge related to these options and shares based upon the difference between the respective exercise and purchase prices and the price to the public in the IPO. Such compensation charge will total approximately $18.4 million, of which approximately $10.6 million was recognized upon consummation of the IPO (for such options and shares which vested upon consummation of the IPO), and the remaining $7.8 million is being recognized over five years (approximately $1.6 million per year) through the second quarter of 2003. An additional $1.6 million in non- cash compensation charges will be recognized through the third quarter of 2001 for stock options issued to certain members of CTI's management prior to the consummation of the share exchange. In July 1998, all of the holders of the Company's Senior Convertible Preferred Stock converted such shares into an aggregate of 9,629,200 shares of the Company's common stock. Upon consummation of the IPO, all of the holders of the Company's then-existing shares of Class A Common Stock, Class B Common Stock, Series A Convertible Preferred Stock, Series B Convertible Preferred Stock and Series C Convertible Preferred Stock converted such shares into an aggregate of 39,842,290 shares of the Company's common stock. 5. Per Share Information Per share information is based on the weighted-average number of common shares outstanding during each period for the basic computation and, if dilutive, the weighted-average number of potential common shares resulting from the assumed conversion of outstanding stock options, warrants and convertible preferred stock for the diluted computation. A reconciliation of the numerators and denominators of the basic and diluted per share computations is as follows: Three Months Nine Months Ended September Ended September 30, 30, ----------------- ----------------- 1997 1998 1997 1998 ------- -------- ------- -------- (In thousands of dollars, except per share amounts) Net loss.............................. $(4,001) $(17,444) $(6,150) $(30,476) Dividends on Senior Convertible Preferred Stock......................

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) The calculations of common shares outstanding for the diluted computations exclude the following potential common shares as of September 30, 1998: (i) options to purchase 16,254,142 shares of common stock at exercise prices ranging from $.40 to $13.00 per share; (ii) warrants to purchase 1,314,990 shares of common stock at an exercise price of $7.50 per share; and (iii) shares of CTI stock which are convertible into 17,443,500 shares of common stock. The inclusion of such potential common shares in the diluted per share computations would be antidilutive since the Company incurred net losses for all periods presented. 6. Contingencies The Company is involved in various claims, lawsuits and proceedings arising in the ordinary course of business. While there are uncertainties inherent in the ultimate outcome of such matters and it is impossible to presently determine the ultimate costs that may be incurred, management believes the resolution of such uncertainties and the incurrence of such costs should not have a material adverse effect on the Company's consolidated financial position or results of operations.

INDEPENDENT AUDITORS' REPORT To the Board of Directors and Stockholders of Crown Castle International Corp.: We have audited the accompanying consolidated balance sheets of Crown Castle International Corp. and subsidiaries as of December 31, 1996 and 1997, and the related consolidated statements of operations, cash flows and stockholders' equity (deficit) for each of the three years in the period ended December 31, 1997. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Crown Castle International Corp. and subsidiaries as of December 31, 1996 and 1997, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 1997, in conformity with generally accepted accounting principles.

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements include the accounts of Crown Castle International Corp. and its wholly owned subsidiaries, collectively referred to herein as the "Company." All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to the prior year's financial statements to be consistent with the presentation in the current year. The Company (a Delaware corporation) was organized on April 20, 1995. On April 27, 1995, the stockholders of Castle Tower Corporation ("CTC") contributed all of the outstanding shares of CTC's stock to the Company in exchange for shares of the Company's stock. CTC (a Delaware corporation) was organized on December 21, 1994 and began operations on January 1, 1995. The Company and CTC have treated this exchange of securities as a reorganization of entities under common control. As such, the transaction has been accounted for as if it were a pooling of interests on January 1, 1995. The Company owns, operates and manages wireless transmission towers and rooftop sites, and also provides an array of related infrastructure and network support services to the wireless communications and radio and television broadcasting industries. The Company's primary business focus is the leasing of antenna space on multiple tenant towers and rooftops to a variety of wireless communications carriers under long-term lease contracts. The Company's transmission towers and rooftop sites are located throughout the United States and in Puerto Rico. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Summary of Significant Accounting Policies Cash Equivalents Cash equivalents consist of highly liquid investments with original maturities of three months or less. Inventories Inventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out (FIFO) method. Property and Equipment Property and equipment is stated at cost, net of accumulated depreciation. Depreciation is computed utilizing the straight-line method at rates based upon the estimated useful lives of the various classes of assets. Additions, renewals and improvements are capitalized, while maintenance and repairs are expensed. Upon the sale or retirement of an asset, the related cost and accumulated depreciation are removed from the accounts and any gain or loss is recognized. In March 1995, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of ("SFAS 121"). SFAS 121 requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of F-17

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) an asset may not be recoverable. SFAS 121 was effective for fiscal years beginning after December 15, 1995. The adoption of SFAS 121 by the Company in 1996 did not have a material impact on its consolidated financial statements. Goodwill and Other Intangible Assets Goodwill and other intangible assets represents the excess of the purchase price for an acquired business over the allocated value of the related net assets (see Note 2). Goodwill is amortized on a straight-line basis over a twenty year life. Other intangible assets (principally the value of existing site rental contracts at Crown Communications) are amortized on a straight- line basis over a ten year life. The carrying value of goodwill and other intangible assets will be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the acquired assets may not be recoverable. If the sum of the estimated future cash flows (undiscounted) expected to result from the use and eventual disposition of an asset is less than the carrying amount of the asset, an impairment loss is recognized. Measurement of an impairment loss is based on the fair value of the asset. Deferred Financing Costs Costs incurred to obtain financing are deferred and amortized over the estimated term of the related borrowing. At December 31, 1997, other accrued liabilities includes $1,160,000 of such costs related to the issuance of the Company's 10 5/8% Senior Discount Notes. Revenue Recognition Site rental revenues are recognized on a monthly basis under lease or management agreements with terms ranging from 12 months to 25 years. Network services revenues from site development, construction and antennae installation activities are recognized under a method which approximates the completed contract method. This method is used because these services are typically completed in three months or less and financial position and results of operations do not vary significantly from those which would result from use of the percentage-of-completion method. These services are considered complete when the terms and conditions of the contract or agreement have been substantially completed. Costs and revenues associated with installations not complete at the end of a period are deferred and recognized when the installation becomes operational. Any losses on contracts are recognized at such time as they become known. Network services revenues from site selection and acquisition activities are recognized under service contracts with customers which provide for billings on a time and materials, cost plus profit, or fixed price basis. Such contracts typically have terms from six months to two years. Revenues are recognized as services are performed with respect to the time and materials contracts. Revenues are recognized using the percentage-of-completion method for cost plus profit and fixed price contracts, measured by the percentage of contract costs incurred to date compared to estimated total contract costs. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Corporate Development Expenses Corporate development expenses represent costs incurred in connection with acquisitions and development of new business initiatives. Income Taxes The Company accounts for income taxes using an asset and liability approach, which requires the recognition of deferred income tax assets and liabilities for the expected future tax consequences of events that F-18

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) have been recognized in the Company's financial statements or tax returns. Deferred income tax assets and liabilities are determined based on the temporary differences between the financial statement and tax bases of assets and liabilities using enacted tax rates. Per Share Information Per share information is based on the weighted-average number of common shares outstanding during each period for the basic computation and, if dilutive, the weighted-average number of potential common shares resulting from the assumed conversion of outstanding stock options, warrants and convertible preferred stock for the diluted computation. A reconciliation of the numerators and denominators of the basic and diluted per share computations is as follows: Years Ended December 31, --------------------------- 1995 1996 1997 -------- -------- --------- (In thousands of dollars, except per share amounts) Net loss.......................................... $ (21) $ (957) $ (11,942) Dividends on Senior Convertible Preferred Stock... -- -- (2,199) ------- ------- --------- Net loss applicable to common stock for basic and diluted computations............................. $ (21) $ (957) $ (14,141) ======= ======= ========= Weighted-average number of common shares outstanding during the period for basic and diluted computations (in thousands).............. 3,316 3,503 6,238 ======= ======= ========= Loss per common share--basic and diluted.......... $ (0.01) $ (0.27) $ (2.27) ======= ======= ========= The calculations of common shares outstanding for the diluted computations exclude the following potential common shares as of December 31, 1997: (i) options to purchase 3,694,375 shares of common stock at exercise prices ranging from $.40 to $7.50 per share; (ii) warrants to purchase 1,314,990 shares of common stock at an exercise price of $7.50 per share; (iii) shares of Senior Convertible Preferred Stock which are convertible into 9,050,060 shares of common stock; and (iv) shares of Series Preferred Stock (see Note 7) which are convertible into 28,888,665 shares of common stock. The inclusion of such potential common shares in the diluted per share computations would be antidilutive since the Company incurred net losses for each of the three years in the period ended December 31, 1997. Financial Instruments The carrying amount of cash and cash equivalents approximates fair value for these instruments. The estimated fair value of the 10 5/8% Senior Discount Notes is based on quoted market prices, and the estimated fair value of the Convertible Secured Subordinated Notes is based on the most recent price at which shares of the Company's stock were sold (see Note 5). The estimated fair value of the other long-term debt is determined based on the current rates offered for similar borrowings. The estimated fair value of the interest rate swap agreement is based on the amount that the Company would receive or pay to terminate the agreement at the balance sheet date. The estimated fair values of the Company's financial instruments, along with the carrying amounts of the related assets (liabilities), are as follows: December 31, 1996 December 31, 1997 ------------------ -------------------- Carrying Fair Carrying Fair Amount Value Amount Value -------- -------- --------- --------- (In thousands of dollars) Cash and cash equivalents.......... $ 7,343 $ 7,343 $ 55,078 $ 55,078 Long-term debt..................... (22,052) (25,736) (156,293) (161,575) Interest rate swap agreement....... -- -- -- (97) F-19

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) The Company's interest rate swap agreement is used to manage interest rate risk. The net settlement amount resulting from this agreement is recognized as an adjustment to interest expense. The Company does not hold or issue derivative financial instruments for trading purposes. Stock Options In October 1995, the FASB issued Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation ("SFAS 123"). SFAS 123 establishes alternative methods of accounting and disclosure for employee stock-based compensation arrangements. The Company has elected to continue the use of the "intrinsic value based method" of accounting for its employee stock option plan (see Note 8). This method does not result in the recognition of compensation expense when employee stock options are granted if the exercise price of the options equals or exceeds the fair market value of the stock at the date of grant. See Note 8 for the disclosures required by SFAS 123. Recent Accounting Pronouncements In February 1997, the FASB issued Statement of Financial Accounting Standards No. 128, Earnings per Share ("SFAS 128"). SFAS 128 establishes new standards for computing and presenting earnings per share ("EPS") amounts for companies with publicly held common stock or potential common stock. The new standards require the presentation of both basic and diluted EPS amounts for companies with complex capital structures. Basic EPS is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period, and excludes the effect of potentially dilutive securities (such as options, warrants and convertible securities) which are convertible into common stock. Dilutive EPS reflects the potential dilution from such convertible securities. SFAS 128 is effective for periods ending after December 15, 1997. The Company has adopted the requirements of SFAS 128 in its financial statements for the year ended December 31, 1997. In February 1997, the FASB issued Statement of Financial Accounting Standards No. 129, Disclosure of Information about Capital Structure ("SFAS 129"). SFAS 129 establishes standards for disclosing information about a company's outstanding debt and equity securities and eliminates exemptions from such reporting requirements for nonpublic companies. SFAS 129 is effective for periods ending after December 15, 1997. The Company has adopted the requirements of SFAS 129 in its financial statements for the year ended December 31, 1996. In June 1997, the FASB issued Statement of Financial Accounting Standards No. 130, Reporting Comprehensive Income ("SFAS 130"). SFAS 130 establishes standards for the reporting and display of comprehensive income in a company's financial statements. Comprehensive income includes all changes in a company's equity accounts (including net income or loss) except investments by, or distributions to, the company's owners. Items which are components of comprehensive income (other than net income or loss) include foreign currency translation adjustments, minimum pension liability adjustments and unrealized gains and losses on certain investments in debt and equity securities. The components of comprehensive income must be reported in a financial statement that is displayed with the same prominence as other financial statements. SFAS 130 is effective for fiscal years beginning after December 15, 1997. The Company will adopt the requirements of SFAS 130 in 1998. In June 1997, the FASB issued Statement of Financial Accounting Standards No. 131, Disclosures about Segments of an Enterprise and Related Information ("SFAS 131"). SFAS 131 establishes standards for the way that public companies report, in their annual financial statements, certain information about their operating segments, their products and services, the geographic areas in which they operate and their major customers. F-20

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) SFAS 131 also requires that certain information about operating segments be reported in interim financial statements. SFAS 131 is effective for periods beginning after December 15, 1997. The Company will adopt the requirements of SFAS 131 in its financial statements for the year ending December 31, 1998. 2. Acquisitions During the three years in the period ended December 31, 1997, the Company consummated a number of business acquisitions which were accounted for using the purchase method. Results of operations and cash flows of the acquired businesses are included in the consolidated financial statements for the periods subsequent to the respective dates of acquisition. Pittencrieff Communications, Inc. ("PCI") From January 9, 1995 through November 1, 1995, the Company acquired 127 telecommunications towers and related assets, net of certain outstanding liabilities, from PCI. The total purchase price of $16,179,000 consisted of $15,122,000 in cash, a note payable to PCI for $762,000 and the assumption of a note payable to a third party for $295,000. The Company entered into a license agreement with PCI under which PCI leases space on certain of the towers for its telecommunications equipment. This license agreement was assumed by Nextel Communications, Inc. ("Nextel") upon its acquisition of PCI in 1997. The license agreement commenced on January 1, 1995 and expires on December 31, 2008, at which time Nextel has the option to renew the license agreement for an additional three year term. The Company also entered into a management agreement with PCI under which PCI managed the towers for the Company. The term of this management agreement was for one year commencing on January 1, 1995. The Company paid a management fee to PCI equal to 15% of the revenues generated by the towers. Such management fees amounted to $553,000 for the year ended December 31, 1995. The Company began managing the towers on January 1, 1996. Spectrum Engineering Company ("Spectrum") On October 30, 1995, the Company acquired substantially all of the property and equipment of Spectrum for $1,185,000 in cash. Spectrum provides management services for building rooftop antenna sites. The Company recognized goodwill of $870,000 in connection with this acquisition. Motorola, Inc. ("Motorola") On June 28, 1996, the Company acquired fifteen telecommunications towers and related assets, and assets related to specialized mobile radio and microwave services, from Motorola in Puerto Rico. The purchase price consisted of $9,919,000 in cash. Motorola provided certain management services related to these assets for a period of ninety days after the closing date. Management fees for such services amounted to $57,000 for the year ended December 31, 1996. Other Acquisitions During 1995 and 1996, the Company acquired a number of other telecommunications towers and related equipment from various sellers. The aggregate total purchase price for these acquisitions of $1,476,000 consisted of $1,211,000 in cash and a $265,000 payable to a seller. TEA Group Incorporated and TeleStructures, Inc. (collectively, "TEA") On May 12, 1997, the Company acquired all of the common stock of TEA. TEA provides telecommunications site selection, acquisition, design and development services. The purchase price of F-21

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) $14,215,000 consisted of $8,120,000 in cash (of which $2,001,000 was paid in 1996 as an option payment), promissory notes payable to the former stockholders of TEA totaling $1,872,000, the assumption of $1,973,000 in outstanding debt and 535,710 shares of the Company's Class B Common Stock valued at $2,250,000 (the estimated fair value of such common stock on that date). The Company recognized goodwill of $9,568,000 in connection with this acquisition. The Company repaid the promissory notes with a portion of the proceeds from the issuance of its 10 5/8% Senior Discount Notes (see Note 5). Crown Communications ("CCM"), Crown Network Systems, Inc. ("CNS") and Crown Mobile Systems, Inc. ("CMS") (collectively, "Crown") On July 11, 1997, the Company entered into an asset purchase and merger agreement with the owners of Crown. On August 15, 1997, such agreement was amended and restated, and the Company acquired (i) substantially all of the assets, net of outstanding liabilities, of CCM and (ii) all of the outstanding common stock of CNS and CMS. Crown provides network services, which includes site selection and acquisition, antenna installation, site development and construction, network design and site maintenance, and owns and operates telecommunications towers and related assets. The purchase price of $185,021,000 consisted of $27,843,000 in cash, a short-term promissory note payable to the former owners of Crown for $76,230,000, the assumption of $26,009,000 in outstanding debt and 7,325,000 shares of the Company's Class B Common Stock valued at $54,939,000 (the estimated fair value of such common stock on that date). The Company recognized goodwill and other intangible assets of $146,103,000 in connection with this acquisition. The Company financed the cash portion of the purchase price with proceeds from the issuance of redeemable preferred stock (see Note 7), and repaid the promissory note with proceeds from the issuance of additional redeemable preferred stock and borrowings under the Senior Credit Facility (see Note 5). In 1997, the Company organized Crown Communication Inc. ("CCI," a Delaware corporation) as a wholly owned subsidiary to own the net assets acquired from CCM and the common stock of CNS and CMS. In January 1998, the Company merged CTC with and into CCI, establishing CCI as the principal operating subsidiary of the Company. Pro Forma Results of Operations (Unaudited) The following unaudited pro forma summary presents consolidated results of operations for the Company as if (i) the Motorola and other acquisitions had been consummated on January 1, 1996 and (ii) the TEA and Crown acquisitions and the investment in Castle Transmission Services (Holdings) Ltd ("CTI") had been consummated as of January 1 for both 1996 and 1997. Appropriate adjustments have been reflected for depreciation and amortization, interest expense, amortization of deferred financing costs, income taxes and certain nonrecurring income and expenses recorded by the Company in connection with the investment in CTI (see Note 4). The pro forma information does not necessarily reflect the actual results that would have been achieved, nor is it necessarily indicative of future consolidated results for the Company.

(1,969) (4,852) ------------ ------------ $ 26,753 $ 81,968 ============ ============ Depreciation expense for the years ended December 31, 1996 and 1997 was $1,151,000 and $2,886,000, respectively. Accumulated depreciation on telecommunications towers and related equipment was $1,820,000 and $3,850,000 at December 31, 1996 and 1997, respectively. At December 31, 1997, minimum rentals receivable under existing operating leases for towers are as follows: years ending December 31, 1998--$15,307,000; 1999--$13,614,000; 2000-- $12,270,000; 2001--$10,108,000; 2002--$3,442,000; thereafter--$3,195,000. 4. Investments in Affiliates Investment in Castle Transmission Services (Holdings) Ltd ("CTI") On February 28, 1997, the Company used a portion of the net proceeds from the sale of the Series C Convertible Preferred Stock (see Note 7) to purchase an ownership interest of approximately 34.3% in CTI (a company incorporated under the laws of England and Wales). The Company led a consortium of investors which provided the equity financing for CTI. The funds invested by the consortium were used by CTI to purchase, through a wholly owned subsidiary, the domestic broadcast transmission division of the British Broadcasting Corporation (the "BBC"). The cost of the Company's investment in CTI amounted to approximately $57,542,000. The Company accounts for its investment in CTI utilizing the equity method of accounting. In March 1997, as compensation for leading the investment consortium, the Company received a fee from CTI amounting to approximately $1,165,000. This fee was recorded as other income by the Company when received. In addition, the Company received approximately $1,679,000 from CTI as reimbursement for costs incurred prior to the closing of the purchase from the BBC. At December 31, 1996, approximately $953,000 of such reimbursable costs are included in other receivables on the Company's consolidated balance sheet. The Company receives a monthly service fee from CTI of approximately $33,000 as compensation for certain management services. This fee is included in network services and other revenues on the Company's consolidated statement of operations. F-23

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) CTI uses the British pound as the functional currency for its operations. The Company translates its equity in the earnings and losses of CTI using the average exchange rate for the period, and translates its investment in CTI using the exchange rate at the end of the period. The cumulative effect of changes in the exchange rate is recorded as a translation adjustment in stockholders' equity. In June 1997, as compensation for the successful completion of the investment in CTI and certain other acquisitions and investments, the Company paid bonuses to two of its executive officers totaling $913,000. These bonuses are included in corporate development expenses on the Company's consolidated statement of operations.

("VISI") On June 23, 1997, the Company made an investment in VISI of $2,000,000 (of which $100,000 was paid in 1996). VISI intends to provide computerized geographic information for a variety of business applications, including the acquisition and design of telecommunications sites. The Company's investment was made in the form of 15,000 shares of VISI's common stock at a price of $2.00 per share, along with a Convertible Subordinated Note for $1,970,000 (the "VISI Note"). The VISI Note is convertible (at the option of the Company) into shares of VISI's common stock at a conversion price of $2.00 per share, bears interest at 7.11% per year and is due on May 31, 2007. The 15,000 shares of common stock purchased by the Company represent an ownership interest of approximately 1.14% in VISI. The Company accounts for its investment in VISI's common stock utilizing the cost method of accounting. F-24

(140) -- ------- -------- $21,912 $156,293 ======= ======== Bank Credit Agreement and Senior Credit Facility On April 26, 1995, CTC entered into a credit agreement with a bank (as amended, the "Bank Credit Agreement"). The Bank Credit Agreement consisted of secured revolving lines of credit (the "Revolving Credit Facility") and a $2,300,000 term note (the "Term Note"). On January 17, 1997, the Bank Credit Agreement was amended to: (i) increase the available borrowings under the Revolving Credit Facility to $50,000,000; (ii) repay the Term Note, along with accrued interest thereon, with borrowings under the Revolving Credit Facility; and (iii) extend the termination date for the Bank Credit Agreement to December 31, 2003. Available borrowings under the Revolving Credit Facility were generally to be used to construct new towers and to finance a portion of the purchase price for towers and related assets. The amount of available borrowings was determined based on the current financial performance (as defined) of: (i) the assets to be acquired; and (ii) assets acquired in previous acquisitions. In addition, up to $5,000,000 of borrowing availability under the Revolving Credit Facility could be used for letters of credit. In October 1997, the Bank Credit Agreement was amended to (i) increase the available borrowings to $100,000,000; (ii) include the lending bank under Crown's bank credit agreement as a participating lender; and (iii) extend the maturity date to December 31, 2004 (as amended, the "Senior Credit Facility"). On October 31, 1997, additional borrowings under the Senior Credit Facility, along with the proceeds from the October issuance of Senior Preferred Stock (see Note 7), were used to repay (i) the promissory note payable to the former stockholders of Crown and (ii) the outstanding borrowings under Crown's bank credit agreement (see Note 2). The Company repaid all of the outstanding borrowings under the Senior Credit Facility with a portion of the proceeds from the issuance of its 10 5/8% Senior Discount Notes (as discussed below). As of December 31, 1997, approximately $93,600,000 of borrowings was available under the Senior Credit Facility, of which $5,000,000 was available for letters of credit. There were no letters of credit outstanding as of December 31, 1997. Upon the merger of CTC into CCI in January 1998, CCI became the primary borrower under the Senior Credit Facility. The amount of available borrowings under the Senior Credit Facility will decrease by $5,000,000 at the end of each calendar quarter beginning on March 31, 2001 until December 31, 2004, at which time any remaining borrowings must be repaid. Under certain circumstances, CCI may be required to make principal prepayments F-25

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) under the Senior Credit Facility in an amount equal to 50% of excess cash flow (as defined), the net cash proceeds from certain asset sales or the net cash proceeds from certain sales of equity or debt securities by the Company. The Senior Credit Facility is secured by substantially all of the assets of the Company's subsidiaries and the Company's pledge of the capital stock of its subsidiaries. In addition, the Senior Credit Facility is guaranteed by the Company. As of December 31, 1997, borrowings under the Senior Credit Facility bear interest at a rate per annum, at the Company's election, equal to the bank's prime rate plus 1.5% or a Eurodollar interbank offered rate (LIBOR) plus 3.25% (10.0% and 8.98%, respectively, at December 31, 1997). The interest rate margins may be reduced by up to 2.25% (non-cumulatively) based on a financial test, determined quarterly. As of December 31, 1997, the financial test permitted a reduction of 1.5% in the interest rate margin for prime rate borrowings and 2.25% in the interest rate margin for LIBOR borrowings. Interest on prime rate loans is due quarterly, while interest on LIBOR loans is due at the end of the period (from one to three months) for which such LIBOR rate is in effect. The Senior Credit Facility requires CCI to maintain certain financial covenants and places restrictions on CCI's ability to, among other things, incur debt and liens, pay dividends, make capital expenditures, dispose of assets, undertake transactions with affiliates and make investments. 10 5/8% Senior Discount Notes due 2007 (the "Notes") On November 25, 1997, the Company issued $251,000,000 aggregate principal amount of the Notes for cash proceeds of $150,010,000 (net of original issue discount). The Company used a portion of the net proceeds from the sale of the Notes to (i) repay all of the outstanding borrowings, including accrued interest thereon, under the Senior Credit Facility; (ii) repay the promissory notes payable, including accrued interest thereon, to the former stockholders of TEA (see Note 2); (iii) repay the Promissory Note payable, including accrued interest thereon, to PCI; and (iv) repay outstanding installment debt assumed in connection with the Crown acquisition (see Note 2). The Notes will not pay any interest until May 15, 2003, at which time semi- annual interest payments will commence and become due on each May 15 and November 15 thereafter. The maturity date of the Notes is November 15, 2007. The Notes are net of unamortized discount of $99,407,000 at December 31, 1997. The Notes are redeemable at the option of the Company, in whole or in part, on or after November 15, 2002 at a price of 105.313% of the principal amount plus accrued interest. The redemption price is reduced annually until November 15, 2005, after which time the Notes are redeemable at par. Prior to November 15, 2000, the Company may redeem up to 35% of the aggregate principal amount of the Notes, at a price of 110.625% of the accreted value thereof, with the net cash proceeds from a public offering of the Company's common stock. The Notes are senior indebtedness of the Company; however, they are unsecured and effectively subordinate to the liabilities of the Company's subsidiaries, which include outstanding borrowings under the Senior Credit Facility. The indenture governing the Notes (the "Indenture") places restrictions on the Company's ability to, among other things, pay dividends and make capital distributions, make investments, incur additional debt and liens, issue additional preferred stock, dispose of assets and undertake transactions with affiliates. As of December 31, 1997, the Company was precluded from paying dividends on its capital stock under the terms of the Indenture. Reporting Requirements Under the Indenture (Unaudited) As of December 31, 1997, the Company does not have any Unrestricted Subsidiaries (as defined in the Indenture). The following information (as such capitalized terms are defined in the Indenture) is presented solely F-26

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) for the purpose of measuring compliance with respect to the terms of the Indenture; such information is not intended as an alternative measure of operating results or cash flow from operations (as determined in accordance with generally accepted accounting principles). Furthermore, the Company's measure of the following information may not be comparable to similarly titled measures of other companies. (In thousands of dollars) --------- Tower Cash Flow, for the three months ended December 31, 1997.... $ 3,118 ======== Consolidated Cash Flow, for the twelve months ended December 31, 1997............................................................ $ 13,150 Less: Tower Cash Flow, for the twelve months ended December 31, 1997............................................................

The Company repaid this note with a portion of the proceeds from the issuance of its 10 5/8% Senior Discount Notes (as discussed above). Convertible Secured Subordinated Notes Payable to Stockholder These notes accrued interest at a rate of 8% per annum, payable at maturity, and were secured by substantially all of CTC's assets. The notes provided that the holder had the option, at any time, to convert such notes, in whole or in part, into shares of the Company's Series A Convertible Preferred Stock at a conversion price of $6.00 per share. On April 27, 1995, a portion of the notes with aggregate principal balances of $743,000 was converted into 123,742 shares of the Company's stock and the related accrued interest was paid to the holder. On February 24, 1997, the remaining $3,125,000 principal amount of the notes was converted into 520,878 shares of the Company's stock and, by mutual agreement with the holder, the related accrued interest was forfeited. Upon conversion of the notes, the principal amount and the forfeited interest were accounted for as increases to redeemable preferred stock and additional paid- in capital, respectively. Restricted Net Assets of Subsidiaries Under the terms of the Senior Credit Facility, the Company's subsidiaries are limited in the amount of dividends which can be paid to the Company. The amount of such dividends is limited to (i) $6,000,000 per year until October 31, 2002, and $33,000,000 per year thereafter, and (ii) an amount to pay income taxes attributable to the Company's subsidiaries. The restricted net assets of the Company's subsidiaries totaled $232,229,000 at December 31, 1997. Interest Rate Swap Agreement The interest rate swap agreement has an outstanding notional amount of $17,925,000 at January 29, 1997 (inception) and terminates on February 24, 1999. The Company pays a fixed rate of 6.28% on the notional amount and receives a floating rate based on LIBOR. This agreement effectively changes the interest rate on $17,925,000 of borrowings under the Senior Credit Facility from a floating rate to a fixed rate of 6.28% plus the applicable margin. The Company does not believe there is any significant exposure to credit risk due to the creditworthiness of the counterparty. In the event of nonperformance by the counterparty, the Company's loss would be limited to any unfavorable interest rate differential. F-27

These loss carryforwards will expire in 2010 through 2012. The utilization of the loss carryforwards is subject to certain limitations. F-28

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) 7. Redeemable Preferred Stock In August 1997, the Company issued 292,995 shares of its Senior Convertible Preferred Stock (the "Senior Preferred Stock") at a price of $100 per share. The net proceeds received by the Company from the sale of such shares amounted to approximately $29,266,000, most of which was used to pay the cash portion of the purchase price for Crown (see Note 2). In October 1997, the Company issued an additional 364,500 shares of its Senior Preferred Stock at a price of $100 per share. The net proceeds received by the Company from the sale of such shares amounted to $36,450,000. This amount, along with borrowings under the Senior Credit Facility, was used to repay the promissory note from the Crown acquisition (see Note 2). The holders of the Senior Preferred Stock are entitled to receive cumulative dividends at the rate of 12.5% per share, compounded annually. At December 31, 1997, such accrued and unpaid dividends amounted to $2,199,000. Any payment of such dividends would be in the form of additional shares of Senior Preferred Stock until such time as the Company is permitted to pay cash dividends on its capital stock under the terms of the Indenture (see Note 5). At the option of the holder, each share of Senior Preferred Stock (plus any accrued and unpaid dividends) is convertible, at any time, into shares of the Company's Class B Common Stock at a conversion price of $7.50 (subject to adjustment in the event of an underwritten public offering of the Company's common stock). At the date of issuance of the Senior Preferred Stock, the Company believes that its conversion price represents the estimated fair value of the Class B Common Stock on that date. The holders of the Senior Preferred Stock are entitled to vote together with the holders of the Company's other preferred stock on an as-converted basis. The Company has the one-time right, within one year from the date of issuance, to redeem 50% of the outstanding shares of Senior Preferred Stock at a price per share which represents an annualized cumulative rate of return of 18%. If not earlier converted or redeemed, the shares of Senior Preferred Stock are subject to mandatory redemption by the Company, at a price per share of $100 plus any accrued and unpaid dividends through that date, upon the earlier of (i) 91 days after the tenth anniversary date of the issuance of the Notes; or (ii) May 15, 2008. The Senior Preferred Stock also calls for a preference, in the event of a liquidation or a change in voting control, equal to a price per share which represents an annualized cumulative rate of return of 18%. With respect to dividend, redemption and liquidation preferences, the rights of the holders of the Senior Preferred Stock are senior to the Company's other preferred and common stock. The purchasers of the Senior Preferred Stock were also issued warrants to purchase an aggregate 1,314,990 shares of the Company's Class B Common Stock at an exercise price of $7.50 per share (subject to adjustment in the event of an underwritten public offering of the Company's common stock). The warrants are exercisable, in whole or in part, at any time until August and October of 2007. At the date of issuance of the warrants, the Company believes that the exercise price represents the estimated fair value of the Class B Common Stock on that date. As such, the Company has not assigned any value to the warrants in its consolidated financial statements. The holders of the Company's Series A Convertible Preferred Stock (the "Series A Preferred Stock"), the Series B Convertible Preferred Stock (the "Series B Preferred Stock") and the Series C Convertible Preferred Stock (the "Series C Preferred Stock") (collectively, the "Series Preferred Stock") are generally entitled to one vote per share on all matters presented to a vote of the Company's stockholders. The holders of the Series Preferred Stock are also entitled to receive dividends, if and when declared, at the same rate as dividends are declared and paid with respect to the Company's common stock. At the option of the holder, each share of Series Preferred Stock is convertible, at any time, into five shares of the Company's Class B Common Stock. Each of the outstanding shares of Series Preferred Stock will automatically convert into five shares of Class B Common Stock in the event of an underwritten public offering of the Company's common stock, subject to certain conditions. F-29

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Upon the earlier of (i) 91 days after the tenth anniversary date of the issuance of the Notes; or (ii) May 15, 2008, the outstanding shares of Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock are redeemable, at the option of the holder, at a price per share of $6.00, $12.00 and $21.00, respectively, plus any accrued and unpaid dividends through the date of redemption. The Series Preferred Stock also call for liquidation preferences equal to such respective redemption prices. With respect to redemption and liquidation preferences, the rights of the holders of the Series C Preferred Stock and the Series B Preferred Stock are senior to the Series A Preferred Stock and the common stock, and the rights of the holders of the Series A Preferred Stock are senior to the common stock. In February and April of 1997, the Company issued 3,529,832 shares of its Series C Preferred Stock at a price of $21.00 per share. The net proceeds received by the Company from the sale of the Series C Preferred Stock amounted to approximately $74,024,000. A portion of this amount was used to purchase the ownership interest in CTI (see Note 4). 8. Stockholders' Equity (Deficit) Common Stock At the option of the holder, each share of the Company's Class A Common Stock is convertible, at any time, into 1.52315 shares of the Company's Class B Common Stock. The holders of the Class B Common Stock are entitled to one vote per share on all matters presented to a vote of the Company's stockholders, and the holders of the Class A Common Stock are entitled to a number of votes equivalent to the number of shares of Class B Common Stock into which their shares of Class A Common Stock are convertible. The holders of the Class A Common Stock are also entitled to receive dividends, if and when declared, on an equivalent basis with the holders of the Class B Common Stock. In the event of an underwritten public offering of its common stock which results in the conversion of the Preferred Stock (see Note 7), the Company may, at its option, require that all outstanding shares of Class A Common Stock be converted into Class B Common Stock. In March 1997, the Company repurchased, and subsequently retired, 814,790 shares of its common stock from a member of the Company's Board of Directors at a cost of approximately $3,422,000. Of this amount, $1,311,000 was recorded as compensation cost and is included in corporate development expense on the Company's consolidated statement of operations. F-30

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Stock Options In 1995, the Company adopted the Crown Castle International Corp. 1995 Stock Option Plan (as amended, the "1995 Stock Option Plan"). Up to 5,765,000 shares of the Company's Class B Common Stock are reserved for awards granted to certain employees, consultants and non-employee directors of the Company and its subsidiaries or affiliates. These options generally vest over periods of up to five years from the date of grant (as determined by the Company's Board of Directors) and have a maximum term of ten years from the date of grant. A summary of awards granted under the 1995 Stock Option Plan is as follows for the years ended December 31, 1995, 1996 and 1997: 1995 1996 1997 ------------------------ ------------------------ ------------------------- Weighted- Weighted- Weighted- Number of Average Number of Average Number of Average Shares Exercise Price Shares Exercise Price Shares Exercise Price --------- -------------- --------- -------------- --------- -------------- Options outstanding at beginning of year...... -- -- 825,000 $ .53 1,050,000 .89 Options granted......... 825,000 $.53 225,000 2.22 3,042,500 5.46 Options exercised....... -- -- -- -- (363,125) .53 Options forfeited....... -- -- -- -- (35,000) 1.20 ------- --------- --------- Options outstanding at end of year............ 825,000 .53 1,050,000 .89 3,694,375 4.69 ======= ========= ========= Options exercisable at end of year............ -- -- 721,250 $ .43 728,875 2.49 ======= ========= ========= In November 1996, options which were granted in 1995 for the purchase of 690,000 shares were modified such that those options became fully vested.

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) The weighted-average fair value of options granted during the years ended December 31, 1995, 1996 and 1997 was $0.09, $0.50 and $1.30, respectively. The fair value of each option was estimated on the date of grant using the Black- Scholes option-pricing model and the following weighted-average assumptions about the options (the minimum value method): Years Ended December 31, ----------------------------- 1995 1996 1997 --------- --------- --------- Risk-free interest rate........................ 5.3% 6.4% 6.1% Expected life.................................. 3.2 years 4.0 years 4.5 years Expected volatility............................ 0% 0% 0% Expected dividend yield........................ 0% 0% 0% The exercise prices for options granted during the years ended December 31, 1995, 1996 and 1997 were equal to or in excess of the estimated fair value of the Company's Class B Common Stock at the date of grant. As such, no compensation cost was recognized for stock options during those years (see Note 1). If compensation cost had been recognized for stock options based on their fair value at the date of grant, the Company's pro forma net loss for the years ended December 31, 1995, 1996 and 1997 would have been $33,000 ($0.01 per share), $973,000 ($0.28 per share) and $12,586,000 ($2.37 per share), respectively. The pro forma effect of stock options on the Company's net loss for those years may not be representative of the pro forma effect for future years due to the impact of vesting and potential future awards. Shares Reserved For Issuance At December 31, 1997, the Company had the following shares reserved for future issuance: Class B Common Stock: Senior Preferred Stock.......................................... 9,050,060 Series A Preferred Stock........................................ 6,916,665 Series B Preferred Stock........................................ 4,322,840 Series C Preferred Stock........................................ 17,649,160 Class A Common Stock............................................ 1,586,460 1995 Stock Option Plan.......................................... 5,765,000 Warrants........................................................ 1,314,990 ---------- 46,605,175 ========== 9. Employee Benefit Plans The Company and its subsidiaries have various defined contribution savings plans covering substantially all employees. Depending on the plan, employees may elect to contribute up to 15% or 20% of their eligible compensation. Certain of the plans provide for partial matching of such contributions. The cost to the Company for these plans amounted to $98,000 for the year ended December 31, 1997. 10. Related Party Transactions The Company leases office space in a building formerly owned by its Chief Executive Officer. Lease payments for such office space amounted to $22,000, $50,000 and $130,000 for the years ended December 31, 1995, 1996 and 1997, respectively. Included in other receivables at December 31, 1997 are amounts due from employees of the Company totaling $499,000. F-32

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) 11. Commitments and Contingencies At December 31, 1997, minimum rental commitments under operating leases are as follows: years ending December 31, 1998--$2,634,000; 1999--$2,483,000; 2000--$2,021,000; 2001--$1,791,000; 2002--$1,131,000; thereafter--$17,228,000. Rental expense for operating leases was $208,000, $277,000 and $1,712,000 for the years ended December 31, 1995, 1996 and 1997, respectively. The Company is involved in various claims, lawsuits and proceedings arising in the ordinary course of business. While there are uncertainties inherent in the ultimate outcome of such matters and it is impossible to presently determine the ultimate costs that may be incurred, management believes the resolution of such uncertainties and the incurrence of such costs should not have a material adverse effect on the Company's consolidated financial position or results of operations. 12. Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and cash equivalents and trade receivables. The Company mitigates its risk with respect to cash and cash equivalents by maintaining such deposits at high credit quality financial institutions and monitoring the credit ratings of those institutions. The Company derives the largest portion of its revenues from customers in the wireless telecommunications industry. In addition, the Company has concentrations of operations in certain geographic areas (primarily Pennsylvania, Texas, New Mexico, Arizona and Puerto Rico). The Company mitigates its concentrations of credit risk with respect to trade receivables by actively monitoring the creditworthiness of its customers. Historically, the Company has not incurred any significant credit related losses. For the years ended December 31, 1995, 1996 and 1997, the Company's revenues from PCI and Nextel amounted to $2,566,000, $2,634,000 and $5,998,000, respectively. 13.

CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) 14. Subsequent Events (Unaudited) On April 24, 1998, the Company entered into a share exchange agreement with certain shareholders of CTI pursuant to which certain of CTI's shareholders have agreed to exchange their shares of CTI for shares of the Company. Upon the consummation of the exchange, the Company's ownership of CTI will increase from approximately 34.3% to approximately 80%. Consummation of the share exchange is subject to a number of significant conditions, including certain third party consents and the consummation of an initial public offering of common stock by the Company. In connection with the share exchange, the Company intends to offer shares of its common stock in an underwritten initial public offering during the summer of 1998. On June 19, 1998, a registration statement in respect of such initial public offering was filed with the Securities and Exchange Commission (as amended, the "Registration Statement") and any securities offered in such initial public offering will only be offered by means of a prospectus forming a part of such Registration Statement. In anticipation of such initial public offering, the Company (i) amended and restated the 1995 Stock Option Plan to, among other things, authorize the issuance of up to 18,000,000 shares of common stock pursuant to awards made thereunder and (ii) approved an amendment to its certificate of incorporation to increase the number of authorized shares of common and preferred stock to 690,000,000 shares and 10,000,000 shares, respectively, and to effect a five- for-one stock split for the shares of common stock then outstanding. The effect of the stock split has been presented retroactively in the Company's consolidated financial statements for all periods presented. During the period from April 24, 1998 through July 15, 1998, the Company granted options to employees and executives for the purchase of 3,236,980 shares of its common stock at an exercise price of $7.50 per share. Of such options, options for 1,810,730 shares will vest upon consummation of the initial public offering and the remaining options for 1,426,250 shares will vest at 20% per year over five years, beginning one year from the date of grant. In addition, the Company has assigned its right to repurchase shares of its common stock from a stockholder (at a price of $6.26 per share) to two individuals (including an expected director nominee) with respect to 100,000 of such shares. Since the granting of these options and the assignment of these rights to repurchase shares occurred subsequent to the date of the share exchange agreement with CTI's shareholders and at prices substantially below the expected price to the public in the initial public offering, the Company will record a non-cash compensation charge related to these options and shares based upon the difference between the respective exercise and purchase prices and the price to the public in the initial public offering. Such compensation charge will total approximately $18.4 million, of which approximately $10.6 million will be recognized upon consummation of the initial public offering (for such options and shares which vest upon consummation of the initial public offering), and the remaining $7.8 million will be recognized over five years (approximately $1.6 million per year) through the second quarter of 2003.

CROWN COMMUNICATIONS NOTES TO COMBINED FINANCIAL STATEMENTS (In thousands of dollars) (1)Basis of Presentation and Summary of Significant Accounting Policies (a) Basis of Presentation The accompanying combined financial statements include the accounts of Crown Communications (CCM), a sole proprietorship, Crown Network Systems, Inc. (CNS), a subchapter S corporation, Crown Mobile Systems, Inc. (CMS), a subchapter S corporation, Airport Communications, Inc. (ACI), a subchapter S corporation and E-90, Ltd. (E-90), a Pennsylvania Business Trust (collectively, Crown Communications or the Company). These entities are all under common ownership. All significant intercompany accounts and transactions have been eliminated. Crown Communications is a communication site development and management company. The Company's core business is the development of high density communication facilities. The majority of these facilities are located throughout western Pennsylvania. The Company leases antenna and transmitter space on communication towers to companies using or providing wireless telephone, paging and specialized mobile radio services. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (b) Cash and Cash Equivalents The Company considers cash in depository institutions and short-term investments with original maturities of three months or less to be cash and cash equivalents. (c) Inventory Inventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out method. (d) Property and Equipment Property and equipment is stated at cost, net of accumulated depreciation. Depreciation on property and equipment is computed utilizing methods which approximate the straight-line method over the estimated useful lives of the assets. Additions, renewals and improvements are capitalized, while maintenance and repairs are expensed. Upon the sale or retirement of an asset, the related cost and accumulated depreciation are removed from the accounts and any gain or loss is recognized. In March 1995, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of ("SFAS 121"). SFAS 121 requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. SFAS 121 is effective for fiscal years beginning after December 15, 1995. The adoption of SFAS 121 by the Company in 1996 did not have a material impact on its combined financial statements. F-38

CROWN COMMUNICATIONS NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued) (In thousands of dollars) (e) Other Assets Other assets include deferred financing costs which are amortized over the estimated term of the related borrowing. (f) Revenue Recognition Equipment sales revenues are recognized when products are delivered to customers. Site rental revenue is recognized ratably over the terms of the respective leases. Such leases have terms that are generally five years. Network services revenues are recognized under a method which approximates the completed contract method. This method is used because typical network services are completed in 3 months or less and financial position and results of operations do not vary significantly from those which would result from use of the percentage-of-completion method. The network services are considered complete at the point in time in which the terms and conditions of the contract and/or agreement have been substantially completed. Revenues from completed contracts which have not been billed at the end of an accounting period are presented as accrued network services. Costs and revenues associated with installations not complete at the end of an accounting period are deferred and recognized when the installation becomes operational. Any losses on contracts are recognized at such time as they become known. (2) Income Taxes CCM is operated as a sole proprietorship and all income or loss is passed through to the personal tax return of the owners. The shareholders for CNS, CMS and ACI have elected under subchapter S of the Internal Revenue Code to pass through all income or loss to the individual tax return of the shareholders. E-90 is operated as a Pennsylvania Business Trust and has elected to be taxed as a partnership. Accordingly, no provision for income taxes has been recorded in the accompanying financial statements. (3) Retirement Savings Plan The Company sponsors a Retirement Savings Plan (the "Plan"), which qualifies for treatment under section 401(k) of the Internal Revenue Code. Substantially all full-time employees are eligible to participate by electing to contribute 1% to 15% of their gross pay to the Plan. Under the Plan, the Company matches a portion of each employee's contribution up to certain limits. Each employee's contribution is fully vested when contributed, and the Company's matching contribution begins vesting after an employee has completed two years of service and becomes fully vested after six years of service. For the years ended December 31, 1995 and 1996, and the seven months ended July 31, 1997, the Company's expense for the Plan was $6, $59 and $44, respectively. F-39

CROWN COMMUNICATIONS NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued) (In thousands of dollars) (4) Commitments and Contingencies The Company leases land, office space and site space on towers and rooftops through contracts that expire in various years through 2095. The Company has purchase and renewal options and is committed to various escalation provisions under certain of these leases. Rental expense under operating leases was $306, $669 and $718 for the years ended December 31, 1995 and 1996, and the seven months ended July 31, 1997, respectively. At July 31, 1997, minimum rental commitments under operating leases are as follows: Years ending December 31, ------------ 1997............................................................ $ 659 1998............................................................ 1,800 1999............................................................ 1,700 2000............................................................ 1,500 2001............................................................ 1,300 Thereafter...................................................... 17,200 ------- $24,159 ======= The Company is involved in various claims and legal actions arising in the ordinary course of business. While there are uncertainties inherent in the ultimate outcome of such matters and it is impossible to presently determine the ultimate costs that may be incurred, management believes the resolution of such uncertainties and the incurrence of such costs should not have a material adverse effect on the Company's combined financial position or results of operations. (5) Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and cash equivalents and accounts receivable. The Company mitigates its risk with respect to cash and cash equivalents by maintaining such deposits at high credit quality financial institutions and monitoring the credit ratings of those institutions. The Company derives the largest portion of its revenues from customers in the wireless telecommunications industry. In addition, the Company has concentrations of operations in western Pennsylvania. The Company mitigates its concentrations of credit risk with respect to accounts receivable by actively monitoring the creditworthiness of its customers. Historically, the Company has not incurred any significant credit related losses. For the year ended December 31, 1995, the Company recognized revenues from two individual customers in the amount of $4,139 and $668. For the year ended December 31, 1996, the Company recognized revenues from three individual customers in the amount of $3,700, $2,600 and $1,400. For the seven months ended July 31, 1997, the Company recognized revenues from three individual customers in the amount of $4,784, $4,246 and $2,377. (6) Subsequent Events In July 1997, the owners of CCM, CNS and CMS entered into an asset purchase and merger agreement with Crown Castle International Corp. ("CCIC"). In August 1997, such agreement was amended and restated, and CCIC acquired (i) substantially all of the assets, net of outstanding liabilities, of CCM and (ii) all of the outstanding common stock of CNS and CMS.

TEA GROUP INCORPORATED NOTES TO FINANCIAL STATEMENTS (In thousands of dollars) (1) Basis of Presentation and Summary of Significant Accounting Policies (a) Basis of Presentation TEA Group Incorporated (the "Company") provides services to the wireless telecommunications and energy transmission industries. These services include providing right-of-way, site acquisition, engineering design and drafting, project management, and staff leasing to wireless telecommunications and energy transmission companies in the United States and internationally. Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and revenues and expenses for the reporting period to prepare these financial statements in conformity with generally accepted accounting principles. Actual results could differ from those estimates. The financial statements for the three months ended March 31, 1996 and 1997 are unaudited; however, they include all adjustments (consisting only of normal recurring adjustments) which, in the opinion of management, are necessary to present fairly the results of operations and cash flows for the three months ended March 31, 1996 and 1997. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the entire year. (b) Revenue Recognition The Company's revenues are derived primarily from service contracts with customers which provide for billings on a time and materials, cost plus profit, or fixed price basis. Such contracts typically have terms from six months to two years. Revenues are recognized as services are performed with respect to the time and materials priced contracts, and are recognized using the percentage-of-completion method for cost plus profit and fixed price contracts, measured by the percentage of contract costs incurred to date to estimated total contract costs. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. (c) Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is provided over the estimated useful lives of the assets on a straight-line basis. Leasehold improvements are amortized over the shorter of their estimated useful lives or the remaining lease term. Property and equipment are depreciated over the following estimated useful lives: Years ----- Leasehold improvements.............................................. 5 Office and computer equipment....................................... 5 Furniture and fixtures.............................................. 7 Computer software................................................... 5 The Company adopted the provisions of Statement of Financial Accounting Standards ("SFAS") 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, on January 1, 1996. This statement requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not F-47

TEA GROUP INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) (In thousands of dollars) be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceed the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Adoption of this statement did not have an impact on the Company's financial statements. (d) Income Taxes The shareholders of the Company have elected to be taxed under the Subchapter S Corporation provisions of the Internal Revenue Code. As a result of this election, Federal and state income taxes related to the results of operations of the Company are passed through to, and are the responsibility of, the Company's shareholders. Accordingly, no provision for income taxes has been recorded in the accompanying financial statements. (e) Fair Value of Financial Instruments The carrying value of the notes payable approximates the estimated fair value for this instrument since it bears interest at a floating market rate. The estimated fair values of the Company's financial instruments, along with the carrying amounts of the related assets (liabilities), are as follows: December 31, December 31, 1995 1996 ----------------- -------------- Carrying Fair Carrying Fair Amount Value Amount Value -------- ------- -------- ----- Cash....................................... $ 5 $ 5 $ -- $ -- Notes payable.............................. (2,733) (2,733) (107) (107) (2) Notes Payable The Company has a revolving line of credit with a bank for working capital purposes (as amended, the "Bank Line of Credit"). The Bank Line of Credit provides for up to $5,000 of working capital borrowings and up to $200 of borrowings for purchases of equipment. At December 31, 1996, outstanding working capital borrowings under the Bank Line of Credit amounted to $107. Borrowings are secured by the Company's receivables, property and equipment, intangibles and cash balances, and bear interest at a rate per annum equal to (i) the bank's prime rate or (ii) a Eurodollar interbank offered rate (LIBOR) plus 2.45% (8.25% and 7.95%, respectively, at December 31, 1996). Interest is payable monthly. The Bank Line of Credit requires the Company to maintain certain financial covenants and places limitations on its ability to, among other things, incur debt and liens, undertake transactions with affiliates and make investments. On July 30, 1997, the Bank Line of Credit was amended to decrease the available borrowings to $3,000 and extend the maturity date to June 30, 1998. Borrowings now bear interest at a rate per annum equal to LIBOR plus 2.7% (8.39% at July 31, 1997). In addition, the amended Bank Line of Credit now restricts the ability of the Company to pay dividends. F-48

TEA GROUP INCORPORATED NOTES TO FINANCIAL STATEMENTS--(Continued) (In thousands of dollars) (3) Commitments The Company has noncancelable operating leases for office space. Future minimum lease payments under the operating leases with remaining terms of one year or more at December 31, 1996 are summarized as follows: Years ending December 31, ------------ 1997............................................................... $316 1998............................................................... 315 1999............................................................... 289 2000............................................................... 43 ---- $963 ==== Rent expense under all cancelable and noncancelable operating leases for 1995 and 1996 was $459 and $608, respectively. (4)Employee Benefit Plan The Company maintains a 401(k) profit sharing and retirement plan (the "Plan") for the benefit of all eligible employees. Employees may elect to contribute up to 15% of their eligible compensation to the Plan. The Plan provides for employer matching contributions at the discretion of the Company's Board of Directors. The Company provided $66 and $29 in expense for contributions for 1995 and 1996, respectively. (5)Related Party Transactions Accounts receivable balances at December 31, 1995 and 1996 include approximately $398 and $94, respectively, from an affiliated company related to expenses incurred by the Company on behalf of the affiliated company. (6) Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and trade receivables. The Company mitigates its risk with respect to cash by maintaining such deposits at high credit quality financial institutions and monitoring the credit ratings of those institutions. The Company derives the largest portion of its revenues from customers in the wireless telecommunications and energy transmission industries. The Company mitigates its concentrations of credit risk with respect to trade receivables by actively monitoring the creditworthiness of its customers. In connection with a disputed receivable with a customer, the Company wrote off $310 during 1996. For the year ended December 31, 1995, the Company had five customers representing 19%, 18%, 16%, 13% and 11% of net revenues, respectively. For the year ended December 31, 1996, the Company had two customers which accounted for 35% and 14% of net revenues, respectively, and one customer which accounted for approximately 59% of accounts receivable at December 31, 1996. (7)Subsequent Event In July 1996, the Company, its shareholders, and certain affiliated companies entered into an agreement with Crown Castle International Corp. ("CCIC") which provided CCIC with an option to acquire various ownership interests in the Company. On May 12, 1997, CCIC acquired all of the Company's common stock. F-49

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND THE BBC HOME SERVICE TRANSMISSION BUSINESS INDEPENDENT AUDITORS' REPORT To the Shareholders and Board of Directors of Castle Transmission Services (Holdings) Ltd: We have audited the accompanying balance sheet of the BBC Home Service Transmission business ("Home Service") at March 31, 1996 and the consolidated balance sheets of Castle Transmission Services (Holdings) Ltd and its subsidiaries ("Castle Transmission") at March 31, 1997 and December 31, 1997 and the profit and loss accounts, cash flow statements and reconciliations of movements in corporate funding for Home Service for the year ended March 31, 1996 and the period from April 1, 1996 to February 27, 1997 and the related consolidated profit and loss accounts, cash flow statements and reconciliations of movements in shareholders' funds for Castle Transmission for the period from February 28, 1997 to March 31, 1997 and the period from April 1, 1997 to December 31, 1997. These financial statements are the responsibility of Castle Transmission's and Home Service's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards in the United Kingdom, which do not differ in any material respect from generally accepted auditing standards in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Home Service at March 31, 1996 and the consolidated financial position of Castle Transmission at March 31, 1997 and December 31, 1997 and the results of operations and cash flows of Home Service for the year ended March 31, 1996 and for the period from April 1, 1996 to February 27, 1997 and of Castle Transmission for the period from February 28, 1997 to March 31, 1997 and for the period from April 1, 1997 to December 31, 1997 in conformity with generally accepted accounting principles in the United Kingdom. Generally accepted accounting principles in the United Kingdom vary in certain respects from generally accepted accounting principles in the United States. Application of generally accepted accounting principles in the United States would have affected results of operations for the year ended March 31, 1996 and the period from April 1, 1996 to February 27, 1997 for Home Service and the period from February 28, 1997 to March 31, 1997 and from April 1, 1997 to December 31, 1997 for Castle Transmission and shareholders' equity at March 31, 1996 for Home Service and at March 31, 1997 and December 31, 1997 for Castle Transmission to the extent summarised in Note 27 to these financial statements.

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND THE BBC HOME SERVICE TRANSMISSION BUSINESS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 1 Basis of preparation As used in the financial statements and related notes, the terms "Castle Transmission" or "the Group" refers to the operations of Castle Transmission Services (Holdings) Ltd and its subsidiaries, Castle Transmission International Ltd ("CTI") which is the successor business and Castle Transmission (Finance) plc ("CTF"). The term "Home Service" refers to the operations of the Home Service Transmission business of the British Broadcasting Corporation ("BBC") which was the predecessor business. These consolidated financial statements have been prepared in accordance with generally accepted accounting principles ("GAAP") applicable in the United Kingdom (UK) and comply with the financial reporting standards of the Institute of Chartered Accountants in England and Wales. A summary of the differences between UK GAAP and United States (US) GAAP as applicable to Castle Transmission is set out in Note 27. Castle Transmission Services (Holdings) Ltd (the "Company") was incorporated on August 27, 1996 and did not trade in the period to February 27, 1997. CTI was incorporated by the BBC on May 9, 1996 and did not trade in the period to February 27, 1997. On February 27, 1997, the assets and liabilities of Home Service were transferred to CTI. On February 28, 1997 CTI was acquired by the Company. During the period between August 27, 1996 and February 27, 1997 Castle Transmission did not trade and received no income and incurred no expenditure. Accordingly the first consolidated profit and loss account for Castle Transmission represents the trading of Castle Transmission for the period from February 28, 1997 to March 31, 1997. CTF was incorporated April 9, 1997. The financial statements for the year ended March 31, 1996 and the period from April 1, 1996 to February 27, 1997 represent the profit and loss accounts, balance sheet, cash flow statements and reconciliations of movements in corporate funding of Home Service. They have been prepared from the separate financial records and management accounts of Home Service. Home Service was charged a management fee by the BBC representing an allocation of certain costs including pension, information technology, occupancy and other administration costs which were incurred centrally by the BBC but which were directly attributable to Home Service. Management believes such allocation is reasonable. Such costs are based on the pension arrangement and the cost structure of the BBC and are not necessarily representative of such costs of Castle Transmission under separate ownership. Home Service did not incur any costs in relation to financing as necessary funding was provided from the BBC through the corporate funding account. No interest is charged by the BBC on such funds because there is no debt at BBC which is attributable to Home Service. Home Service was not a separate legal entity and therefore was not directly subject to taxation on its results. The BBC is a not-for-profit organisation and is not subject to taxation except to the extent of activities undertaken with the objective of making a profit, including all external activities (principally site sharing and commercial projects). The tax charge attributable to Home Service has been calculated as if Home Service were under separate ownership since April 1, 1994 and as if all of its results of operations were subject to normal taxation. Redundancy costs were incurred by the BBC which related to Home Service staff. The redundancy costs amounted to (Pounds)1.1m in 1996 and (Pounds)0.6m in the period from April 1, 1996 to February 27, 1997. The redundancy programmes were controlled by the BBC and the costs were not recharged to Home Service. No adjustment has been made in the Home Service financial statements for these costs because any costs incurred would have been reflected in the cost base of Home Service, and as described in note 25 would have been off-set by an increase in turnover from the BBC. The consolidated financial statements for the two months ended February 27, 1997 and as of and for the eight months ended August 31, 1998 are unaudited; however, in the opinion of all the directors, all adjustments F-55

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND THE BBC HOME SERVICE TRANSMISSION BUSINESS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (consisting of normal recurring adjustments) necessary for a fair presentation have been made. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end. Operating results for the eight month period ended August 31, 1998 are not necessarily indicative of the results that may be expected for the year ending December 31, 1998. 2 Accounting policies The following accounting policies have been applied consistently in dealing with items which are considered material in relation to the financial statements of Home Service and the consolidated financial statements of Castle Transmission. Basis of consolidation The consolidated financial statements include the financial statements of the Company and its subsidiaries made up to March 31, 1997 and December 31, 1997 after elimination of all significant inter-company accounts and transactions. The acquisition method of accounting has been adopted. Under this method, the results of subsidiaries acquired or disposed of in the period are included in the consolidated profit and loss account from the date of acquisition or up to the date of disposal. Goodwill Purchased goodwill on acquisitions (representing the excess of the fair value of the consideration given over the fair value of the separable net assets acquired) is capitalised and amortised over 20 years, the period over which the Directors consider that the Group will derive economic benefits. Tangible fixed assets and depreciation Depreciation is provided to write off the cost or valuation less the estimated residual value of tangible fixed assets by equal instalments over their estimated useful economic lives as follows: Land and buildings Home Service Castle Transmission -------------- ------------------- Freehold and long leasehold buildings... 50 years 50 years Freehold and long leasehold improve- ments.................................. 20 years 20 years Short leasehold land and buildings...... Unexpired term Unexpired term No depreciation is provided on freehold land................................... Plant and equipment Home Service Castle Transmission ------------ ------------------- Transmitters and power plant............... 25 years 20 years Electric and mechanical infrastructure..... 10-20 years 10-20 years Other plant and machinery.................. 3-10 years 3-10 years Computer equipment......................... 5 years 5 years Motor vehicles............................. -- 3 years Strategic spares, which comprise those spares that are vital to the operation of the transmission system, are included in the capitalised value of the asset to which they relate and are depreciated over the life of the asset. Assets under construction are included within fixed assets. The associated labour costs are capitalised using a predetermined labour rate, and any over or under recoveries are recognised in the profit and loss account in the period in which they arise. F-56

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND THE BBC HOME SERVICE TRANSMISSION BUSINESS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Foreign currencies Transactions in foreign currencies are translated at the rate of exchange ruling at the date of the transaction. Monetary assets and liabilities, to the extent that they are denominated in foreign currency, are retranslated at the rate of exchange ruling at the balance sheet date and gains or losses are included in the profit and loss account. Leases Where the Company enters into a lease which entails taking substantially all the risks and rewards of ownership of an asset, the lease is treated as a "finance lease'. The asset is recorded in the balance sheet as a tangible fixed asset and is depreciated over its useful life or term of the lease, whichever is shorter. Future instalments under such leases, net of finance charges, are included within creditors. Rentals payable are apportioned between the finance element, which is charged to the profit and loss account, and the capital element which reduces the outstanding obligation for future instalments. Operating lease rentals are charged to the profit and loss account on a straight line basis over the period of the lease. Pensions The pension costs charged in the period include costs incurred, at the agreed employer's contribution rate. See note 20 for further details. Stocks Stocks held are general maintenance spares and manufacturing stocks. Stocks are stated at the lower of weighted average cost and net realisable value. Work in progress For individual projects, the fees on account and project costs are recorded in work in progress. When a project is complete, the project balances are transferred to turnover and cost of sales as appropriate, and the net profit is recognised. Where the payments on account are in excess of project costs, these are recorded as payments on account. Provision is made for any losses as soon as they are foreseen. Taxation The charge for taxation is based on the result for the period and takes into account taxation deferred because of timing differences between the treatment of certain items for taxation and accounting purposes. Provision is made for deferred tax only to the extent that it is probable that an actual liability will crystallise. Turnover Turnover represents the amounts (excluding value added tax) derived from the provision of transmission and maintenance contracts, site sharing arrangements and commercial projects. Revenue is recognised on the basis of contracts or as services are provided to customers. Issue costs Costs incurred in raising funds are deducted from the amount raised and amortised over the life of the debt facility on a constant yield basis. F-57

These shares were issued to certain members of the management team. Management believes that this sale price reflects the fair value of the shares at that date. The Redeemable Preference Shares are redeemable on December 31, 2050. The Company may also redeem any number of Redeemable Preference Shares at any time by giving at least two business days' notice in writing to the holders. In addition, the Company shall redeem in full all the Redeemable Preference Shares on or before the earlier or any listing or sale of 87.5 percent or more of the issued share capital.

CTI had itself acquired the assets and liabilities of Home Service on February 27, 1997, with the intention of CTI's ensuing disposal to the Company. As the two transactions were enacted for the purpose of the sale and purchase of Home Service, a provisional fair value exercise was performed by CTI on the acquisition of the trade and net assets of Home Service on 27 February 1997, giving rise to acquisition goodwill of (Pounds)39.6 million. The fair value exercise was only provisional at March 31, 1997 as the elapsed time had not been sufficient to form a final judgement on the fair value adjustments. The fair value exercise has now been finalised and as a result goodwill has been increased by (Pounds)1.2 million. See note 24. The consideration paid for the acquisition of the shares of CTI by the Company amounted to (Pounds)45 million plus fees of (Pounds)7.5 million. (Pounds)7.2 million had been paid or accrued at March 31, 1997, which gave rise to additional goodwill of (Pounds)7.5 million. F-67

Pension scheme assets are not apportioned between different parts of the BBC. The pension rate charged to Home Service was 4.5 percent for the year ended March 31, 1996 and for the period from April 1, 1996 to February 27, 1997. This charge took into account the surplus shown by the last actuarial valuation of the BBC scheme. Amounts charged were as follows: (Pounds)521,000 in 1996 and (Pounds)491,000 in the period from April 1, 1996 to February 27, 1997. F-68

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND THE BBC HOME SERVICE TRANSMISSION BUSINESS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Castle Transmission The pension charge is not comparable between Home Service and Castle Transmission due to the former having a reduced charge as a result of the surplus in the BBC Pension scheme. Under the terms of the sale agreement Castle Transmission was temporarily participating in the BBC Pension scheme until July 31, 1997. From August 1, 1997 the Group was committed under the sale agreement to establish its own pension scheme. In respect of past service benefits, members were able to choose between transferring past service benefits to the Group scheme or leaving them in the BBC Pension scheme. To the extent that past service benefits were transferred, the BBC Pension scheme made a full transfer payment to the Group scheme calculated in accordance with the actuarial basis as set out in the sale agreement. The pension charge for the period from February 28, 1997 to March 31, 1997 included in the accounts represented contributions payable to the BBC Pension scheme and amounted to (Pounds)156,000. Contributions are calculated at the employers' contribution rate of 17.7 per cent of pensionable salary. The contribution rate has been determined by a qualified actuary and is specified in the sale agreement. At August 1, 1997 Castle Transmission established its own pension scheme. This is a defined benefit scheme and assets were transferred from the BBC Pension scheme to the extent that members chose to transfer past benefits. From August 1, the Castle Transmission Pension Scheme will be liable in respect of future pension benefits. The pension charge for the period from April 1, 1997 to December 31, 1997 was (Pounds)1,490,000. There were no outstanding or prepaid contributions at either the beginning or end of the financial periods. The Group also established a defined contribution scheme which will have a backdated start date of August 1, 1997. This scheme will be open to employees joining the Group after March 1, 1997. The defined benefit scheme will not be open to these employees. The pensionable charge for the period from April 1, 1997 to December 31, 1997 represents contributions under this scheme amounting to (Pounds)nil. 21 Reconciliation of operating profit to operating cash flows Home Service Castle Transmission --------------------------- --------------------------------- Period from Period from Period from Year Ended April 1, 1996 February 28, 1997 April 1, 1997 March 31, to February 27, to March 31, to December 31, 1996 1997 1997 1997 ----------- --------------- ----------------- --------------- (Pounds)000 (Pounds)000 (Pounds)000 (Pounds)000 Operating profit........ 7,785 14,002 1,245 8,776 Depreciation and amortisation charge.... 12,835 13,038 1,819 16,854 (Increase)/Decrease in stocks.................

Fair value adjustments The fair value adjustments result from the completion of the fair value exercise performed by CTI on the acquisition of Home Service and the under accrual of fees by the Company, in relation to the acquisition of CTI, at March 31, 1997. The (Pounds)1,237,000 increase in goodwill relates predominantly to the provision of (Pounds)1,250,000 in respect of a dispute over wind loading fees. This dispute was an existing contingent liability at the date of acquisition and consequently provision has been made against the fair value of the assets and liabilities of Home Service at February 27, 1998. 25 Related party disclosures Home Service Throughout the year ended March, 31 1996 and the period from April 1, 1996 to February 27, 1997, Home Service entered into a number of transactions with other parts of the BBC. Substantially all of these transactions are exempt from the disclosure provisions of FRS 8 "Related Party Disclosures" as they have been undertaken between different parts of the BBC, and are eliminated in the consolidated accounts of the BBC. However, brief details of the nature of these transactions are set out below. The majority of Home Service's income arises from trading with other parts of the BBC. Prices are set at BBC group level on the basis of cost budgets prepared by Home Service. The aggregate value of such sales in each of the years covered by the combined financial statements is given in Note 3. Administrative costs include expenses re-charged to Home Service by the BBC. These re-charges related to costs incurred centrally in respect of pension, information technology, occupancy and other administration costs. These charges amounted to (Pounds)5.8 million in 1996 and (Pounds)1.2 million in the period between April 1, 1996 and February 27, 1997. The reduced charge for the period to February 27, 1997 is a result of more functions being carried out by employees of Home Service in preparation for the change to a stand alone entity. F-71

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND THE BBC HOME SERVICE TRANSMISSION BUSINESS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued) In addition, re-charges were also made for distribution costs relating to telecommunication links between the BBC and the transmitting stations and these were then internally re-charged to other parts of the BBC. The charges amounted to (Pounds)5.6 million in 1996 and (Pounds)6.4 million in the period between April 1, 1996 and February 27, 1997. Castle Transmission The Shareholders of Castle Transmission are: Crown Castle International Corp. ("CCIC", formerly Castle Tower Holding Corp.), Candover Investments plc and funds managed by it ("Candover"), TeleDiffusion de France International S.A ("TdF") and Berkshire Partners LLC and funds managed by it ("Berkshire"). They are considered to be related parties as they are the consortium who own 99 percent of the shares of the Company. Castle Transmission paid fees to shareholders in respect of expenses incurred during the acquisition and success fees. Castle Transmission also has management agreements with CCIC (for commercial and financial advice and training and consultancy) and TdF (for technical advice and consulting), these agreements run for five years from February 28, 1997. Fees are payable on the basis of an annual fee for agreed services provided to Castle Transmission, together with fees on a commercial arm's length basis for any additional services provided. In addition Castle Transmission has agreed to reimburse shareholders' expenses in relation to attendance at board meetings. The amounts paid and accrued by the Company during the period were as follows: Total amounts payable at Amounts Amounts Amounts March 31, Related party expensed capitalised paid 1997 ------------- ----------- ----------- ----------- ------------- (Pounds)000 (Pounds)000 (Pounds)000 (Pounds)000 CCIC....................... 20 1,763 1,763 20 Candover................... 1 244 244 1 TdF........................ -- 129 -- 129 Berkshire.................. 1 315 316 -- --- ----- ----- --- 22 2,451 2,323 150 === ===== ===== === Total amounts Total amounts payable at payable at March 31, Amounts Amounts Amounts December 31, Related party 1997 expensed capitalised paid 1997 ------------- ------------- ----------- ----------- ----------- ------------- (Pounds)000 (Pounds)000 (Pounds)000 (Pounds)000 (Pounds)000 CCIC.................... 20 253 -- 246 27 Candover................ 1 16 -- 13 4 TdF..................... 129 -- -- 129 -- Berkshire............... -- 55 -- 43 12 --- --- --- --- --- 150 324 -- 431 43 === === === === === Ongoing BBC relationship At the time of the acquisition of Home Service, Castle Transmission entered into a ten year transmission contract with the BBC for the provision of domestic terrestrial analogue television and radio transmission services expiring on March 31, 2007. Thereafter, the contract continues until terminated by twelve months notice by either party on March 31 in any contract year from and including March 31, 2007. It may also be terminated early if certain conditions are met. F-72

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND THF BBC HOME SERVICE TRANSMISSION BUSINESS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued) The contract provides for charges of approximately (Pounds)46 million to be payable by the BBC to Castle Transmission for the year to March 31, 1998. Castle Transmission's charges for subsequent years of the contract are largely determined by a formula which escalates the majority of the charges by a factor which is 1% below the rate of increase in the Retail Price Index over the previous calendar year. Those elements of the charges which are subject to the escalation formula for the contract year commencing April 1, 1998 amount to approximately (Pounds)46 million. 26 Post balance sheet events On January 23, 1998, the Board of Directors adopted: (i) the All Employee Share Option Scheme; (ii) the Management Share Option Scheme; and (iii) individual share option arrangements for certain directors of the Company. The All Employee Share Option Scheme provides for an unlimited number of shares to be granted to all employees of the Company. The Board may select any number of individuals to apply for the grant of an option. Not later than thirty days following the date by which an application must be made, the Board may grant to each applicant the number of options specified in his application. These options may be exercised at the earliest of the third anniversary of the date of grant, in the event of a flotation or in the event of a take-over, reconstruction, liquidation or option exchange as set out in the Scheme rules. For options granted under this scheme the option price and the number of shares will not change during the life of the option. Under the terms of the Management Share Option Scheme and the individual share option arrangements, share options may be granted to employees or directors of the Company as determined by the Board of Directors up to a maximum of 460,000 Ordinary Shares and 459,540,000 Redeemable Preference Shares. Options will vest over periods of up to four years and have a maximum term of up to nine years. For options over 223,333 Ordinary Shares and 223,110,000 Redeemable Preference Shares, the option price and the number of shares will not change during the life of the option. The remaining options are subject to certain performance criteria. On January 23, 1998 and January 30, 1998 the Company granted options to purchase an aggregate of 460,000 Ordinary Shares and 459,540,000 Redeemable Preference Shares under the terms of the individual share option arrangements and the Management Share Option Scheme, respectively. The weighted average price for such options is 1.16 pence for Ordinary Shares and 1.16 pence for Redeemable Preference Shares. The weighted average vesting period for such options is 1.13 years. Any accounting charge resulting from a difference between the fair value of the rights to the shares at the date of grant and the amount of consideration to be paid for the shares will be charged to the profit and loss account in the year to December 31, 1998 and subsequent years according to the vesting provisions of the arrangements. Where the options are subject to performance criteria, the amount initially recognised will be based on a reasonable expectation of the extent to which these criteria will be met and will be subject to subsequent adjustments as necessary to deal with changes in the probability of performance criteria being met. Update of post balance sheet events (Unaudited) On March 23, 1998, the Company granted options to purchase an aggregate of 40,750 Ordinary Shares and 40,709,250 Redeemable Preference Shares under the terms of the All Employee Share Option Scheme. The price for such options is 1.00 pence for both Ordinary Shares and Redeemable Preference Shares. The vesting period for such options is three years. The accounting charge related to all share options included within the unaudited consolidated financial statements for the eight months ended August 31, 1998 is (Pounds)2,330,000. F-73

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND THE BBC HOME SERVICE TRANSMISSION BUSINESS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued) On April 23, 1998, the Board of Directors adopted share option arrangements for certain individuals. On that same date, the Company granted options to purchase 60,000 Ordinary Shares and 59,940,000 Redeemable Preference Shares under the terms of such share option arrangements. These options will vest over a period of four years and have a maximum term of six years. The weighted average price of such options is 1.75 pence for both Ordinary Shares and Redeemable Preference Shares. The weighted average vesting period for such options is two years. On July 1, 1998 and July 15, 1998, CCIC granted options to purchase 59,932 ordinary shares in CCIC to employees of CTI under terms of individual share option arrangements. The weighted average price for such options is $37.54. These options vested on August 18, 1998. The accounting charge related to these options included in the unaudited consolidated financial statements for the eight months ended August 31, 1998 is (Pounds)978,000. On July 15, 1998, the Board of Directors of the Company resolved that the Management Share Option Scheme would not be subject to any performance criteria and would vest on a time basis only. An August 11, 1998, the Company granted options to purchase 15,690 Ordinary Shares and 15,674,310 Redeemable Preference Shares under the terms of the Management Share Option Scheme.

In addition, CCIC subscribed for 10,210 Ordinary Shares and 10,199,790 Redeemable Preference Shares for cash at a premium of 1.5 pence per share. On August 21, 1998, the Company became an 80% owned subsidiary of CCIC. On that same date, (i) all issued and unissued Redeemable Preference Shares were redesignated as Ordinary Shares; and (ii) all existing options to purchase shares in the Company were converted into options to purchase shares in CCIC at the rate of 7 shares in CCIC for every 1000 shares in the Company. 27 Summary of differences between United Kingdom and United States generally accepted accounting principles These consolidated financial statements have been prepared in accordance with UK GAAP, which differ in certain respects from US GAAP. The differences that affect Home Service and Castle Transmission are set out below: (a) Tangible fixed assets During 1993 Home Service revalued upwards its investments in certain identifiable tangible fixed assets. Such upward revaluation is not permissible under US GAAP. Rather, depreciated historical cost must be used in financial statements prepared in accordance with US GAAP. In the period between April 1, 1996 and February 27, 1997 there were a number of transfers of fixed assets to and from other parts of the BBC as explained in note 10. For US GAAP purposes these transfers have been accounted for under the as-if-pooling-of-interests method for transactions between entities under common control. F-74

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND THE BBC HOME SERVICE TRANSMISSION BUSINESS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (b) Deferred taxation Under UK GAAP, deferred taxes are accounted for to the extent that it is considered probable that a liability or asset will crystallise in the foreseeable future. Under US GAAP, deferred taxes are accounted for on all timing differences and a valuation allowance is established in respect of those deferred tax assets where it is more likely than not that some portion will remain unrealised. Deferred tax also arises in relation to the tax effect of other US GAAP adjustments. (c) Pensions The Group accounts for costs of pensions under the rules set out in the UK accounting standards. US GAAP is more prescriptive in respect of actuarial assumptions and the allocation of costs to accounting periods. (d) Capitalised interest Under US GAAP, interest incurred during the construction periods of tangible fixed assets is capitalised and depreciated over the life of the assets. (e) Redeemable preference shares Under UK GAAP, preference shares with mandatory redemption features or redeemable at the option of the security holder are classified as a component of total shareholders' funds. US GAAP requires such redeemable preference shares to be classified outside of shareholders' funds. F-75

CASTLE TRANSMISSION SERVICES (HOLDINGS) LTD AND SUBSIDIARIES AND THF BBC HOME SERVICE TRANSMISSION BUSINESS NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (f) Cash flow statement Under US GAAP various items would be reclassified within the consolidated cash flow statement. In particular, interest received, interest paid and taxation would be part of net cash flows from operating activities, and dividends paid would be included within net cash flow from financing. In addition, under US GAAP, acquisitions and disposals would be included as investing activities. Movements in those current investments which are included under the heading of cash under US GAAP form part of the movements entitled "Management of liquid resources" in the consolidated cash flow statements.

INDEPENDENT AUDITORS' REPORT To the Board of Directors and Stockholders of Crown Castle International Corp.: We have audited the accompanying statement of net assets of Bell Atlantic Mobile Tower Operations as of September 30, 1998, and the related statements of revenues and direct expenses for the nine months ended September 30, 1998 and the year ended December 31, 1997. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audit in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the statement of net assets and the related statements of revenues and direct expenses are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the statement of net assets and the related statements of revenues and direct expenses. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the statement of net assets and the related statements of revenues and direct expenses. We believe that our audit provides a reasonable basis for our opinion. The statements of net assets and revenues and direct expenses were prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission. As discussed in note 1, such statements do not reflect certain corporate overhead expenses incurred by Bell Atlantic Mobile, the contributor of the net assets, on behalf of the tower operations. In our opinion, the statements referred to above present fairly, in all material respects, the net assets of Bell Atlantic Mobile Tower Operations as of September 30, 1998, and the related revenues and direct expenses for the nine months ended September 30, 1998 and the year ended December 31, 1997, in conformity with generally accepted accounting principles.

BELL ATLANTIC MOBILE TOWER OPERATIONS NOTES TO FINANCIAL STATEMENTS (In thousands of dollars) 1. Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation On December 8, 1998 Crown Castle International Corp. ("CCIC") and Bell Atlantic Mobile and certain entities controlled by Bell Atlantic Mobile ("BAM") entered into a formation agreement in order to create Crown Atlantic Company LLC ("Crown Atlantic"). Under the terms of the agreement, BAM will contribute tower structures and certain related assets while CCIC will contribute cash and shares of its common stock to Crown Atlantic and its parent company, respectively. The tower structures and related assets consist of the tower facilities that were previously part of BAM's cellular operations. Their locations span New York, New England, Philadelphia, Pittsburgh, Washington-Baltimore and certain areas in the Southeast and Southwest. Under the formation agreement, Crown Atlantic will assume all obligations of BAM as landlord, licensor or tenant relating to the tower space leases with respect to the period after the closing date. Crown Atlantic will also assume all obligations of BAM subsequent to the closing date relating to the operation of the towers and any contracts entered into by BAM during the ordinary course of business of BAM relating to the towers but only to the extent that such contracts were chosen to be included in the obligations assumed by Crown Atlantic. Under the terms of the formation agreement, Crown Atlantic did not assume certain liabilities as defined in the actual terms of the formation agreement. The accompanying statement of net assets reflects the assets to be contributed by BAM to Crown Atlantic pursuant to the formation agreement. The statement of net assets reflects BAM's historical carrying values of the contributed assets, adjusted to exclude certain assets which will not be contributed as part of the formation agreement. The accompanying statements of revenue and direct expenses reflect operations related to the tower assets to be contributed by BAM to Crown Atlantic per the formation agreement. Certain direct and indirect operating costs of BAM have been allocated and included in the costs of operations. The allocated amounts totaled $3,501 and $2,811 for the year ended December 31, 1997 and the nine months ended September 30, 1998, respectively. Such allocations are based on determinations that management believes are reasonable, but may not be necessarily indicative of such costs incurred by Crown Atlantic in the future. The statements of revenues and direct expenses do not include allocated costs related to general corporate overhead, interest expense and income taxes and therefore may not be indicative of future operations. The accompanying statement of net assets and the related statements of revenues and direct expenses were prepared for the purpose of complying with the requirements of the Securities and Exchange Commission and are not intended to be a complete presentation of Bell Atlantic Mobile's assets and liabilities or revenues and expenses. Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Revenue Recognition Site rental revenues are recognized on a monthly basis under lease or management agreements. Site rental revenues represent charges for tower usage billed to third party customers under lease arrangements. F-81

PART II INFORMATION NOT REQUIRED IN THE PROSPECTUS Item 20. Indemnification of Directors and Officers Section 145 of the General Corporation Law of the State of Delaware ("DGCL") provides that a corporation has the power to indemnify any director or officer, or former director or officer, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) against the expenses (including attorney's fees), judgments, fines or amounts paid in settlement actually and reasonably incurred by them in connection with the defense of any action by reason of being or having been directors or officers, if such person shall have acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding; provided that such person had no reasonable cause to believe his conduct was unlawful, except that, if such action shall be in the right of the corporation, no such indemnification shall be provided as to any claim, issue or matter as to which such person shall have been judged to have been liable to the corporation unless and to the extent that the Court of Chancery of the State of Delaware (the "Court of Chancery"), or any court in such suit or action was brought, shall determine upon application that, in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnify for such expenses as such court shall deem proper. Accordingly, the Restated Certificate of Incorporation of the Company (filed herewith as Exhibit 3.1) provide that the Company shall, to the maximum extent permitted under the DGCL indemnify each person who is or was a director or officer of the Company. The Company may, by action of the Board of Directors, indemnify other employees and agents of the Corporation, directors, officers, employees or agents of a subsidiary, and each person serving as a director, officer, partner, member, employee or agent or another corporation, partnership, limited liability company, joint venture, trust or other enterprise, at the request of the Company, with the same scope and effect as the indemnification of directors and officers of the Company. Notwithstanding the foregoing, the Company shall be required to indemnify any person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board of Directors or is a proceeding to enforce such person's claim to indemnification pursuant to the rights granted by the Restated Certificate of Incorporation or otherwise by the Company. The Company may also enter into one or more agreements with any person which provide for indemnification greater or different than that provided in the Restated Certificate of Incorporation. Furthermore, a director of the Company shall not be liable to the Company or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (1) for any breach of the director's duty of loyalty to the Company or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL, or (4) for any transaction from which the director derived an improper personal benefit. The Company's By-laws provide that each person who was or is made a party or is threatened to be made a party to or is involved in any manner in any threatened, pending or completed action, suit, or proceeding, whether civil, criminal, administrative or investigative ("Proceeding"), by reason of the fact that he or she or a person of whom he or she is the legal representative is or was a director or officer of the Company or, while a director or officer of the Company, a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise shall be indemnified and held harmless by the Company to the fullest extent permitted by the DGCL. Such indemnification shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that the Company shall indemnify any such person seeking indemnification in connection with a Proceeding (or part thereof) initiated by such person only if such Proceeding (or part thereof) was authorized by the Board of Directors or is a Proceeding to enforce such person's claim to indemnification pursuant to the rights granted by the Company's By-laws. The Company shall pay the expenses incurred by any person described in the first two sentences of this paragraph in defending any such Proceeding in advance of its final disposition upon, to the extent such an II-1

undertaking is required by applicable law, receipt of an undertaking by or on behalf of such person to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Company as authorized in the Company's By-laws or otherwise. The Company's By-laws further provide that the indemnification and the advancement of expenses incurred in defending a Proceeding prior to its final disposition provided by, or granted pursuant to, the Company's By-laws shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the Restated Certificate of Incorporation, other provision of the Company's By-laws or otherwise. The Company may also maintain insurance, at its expense, to protect itself and any person who is or was a director, officer, partner, member, employee or agent of the Company or a subsidiary or of another corporation, partnership, limited liability company, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under the DGCL. The Company's By-laws further provide that the Company may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification, and rights to be paid by the Company the expenses incurred in defending any Proceeding in advance of its final disposition, to any person who is or was an employee or agent (other than a director or officer) of the Company or a subsidiary thereof and to any person who is or was serving at the request of the Company or a subsidiary thereof as a director, officer, partner, member, employee or agent of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, including service with respect to employee benefit plans maintained or sponsored by the Company or a subsidiary thereof, to the fullest extent of the provisions of the Company's By-laws with respect to the indemnification and advancement of expenses of directors and officers of the Company.

Item 22. Undertakings The undersigned Registrant hereby undertakes that insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions described under Item 20 above, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted against the Registrant by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. The undersigned Registrant hereby undertakes (i) to respond to requests for information that are incorporated by reference into the Prospectus pursuant to Item 4, 10(b), 11, or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This undertaking also includes documents filed subsequent to the effective date of the Registration Statement through the date of responding to the request. The undersigned Registrant hereby undertakes to supply by means of a post- effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the Registration Statement when it became effective. The undersigned Registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this Registration Statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the undersigned undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form. The undersigned Registrant hereby undertakes that every prospectus: (i) that is filed pursuant to the immediately preceding paragraph or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post- effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

4 C. Class A Common Stock. --------------------- 1. General. The holders of shares of Class A Common Stock shall be -------- entitled to one vote for each such share upon all questions presented to the stockholders, except with respect to the election of Directors by the Stockholders; provided, however, that the holders of shares of Class A Common -------- ------- Stock shall have the right to vote on Directors as set forth in Section C.2 of this Article IV. The holders of the shares of Class A Common Stock shall at all times, except as otherwise provided in this Restated Certificate of Incorporation (including the immediately preceding sentence) or as required by applicable law, (i) vote, together with the holders of shares of Common Stock and any other class or series of stock of the Corporation accorded such general voting rights, as a single class and (ii) receive any dividends or distributions declared or paid on the Common Stock in equal amounts per share and without preference or priority of either the Common Stock or the Class A Common Stock over the other.

Election of Directors. ---------------------- (a) General Right of Election. So long as TDF (as hereinafter -------------------------- defined) is Qualified (as such term is defined in the Governance Agreement), holders of shares of Class A Common Stock voting as a separate class shall have the right to elect two Directors (the "Class A Directors") to the Board of Directors of the Corporation; provided, however, that if -------- ------- TDF is not Qualified, so long as the Ownership Interest (as such term is defined in the Governance Agreement) of the TDF Group is at least 5%, holders of Class A Common Stock voting as a separate class shall have the right to elect one Director to the Board of Directors of the Corporation. (b) Mandatory Termination and Replacement. Each Class A Director -------------------------------------- shall serve until the next annual meeting of the stockholders and until such Director's successor has been elected and qualified, subject to such Director's earlier death, resignation, removal or retirement. Upon (i) the number of Directors the holders of the Class A Common Stock are entitled to

5 elect being reduced from two to one Director as a result of TDF no longer being Qualified, the term of office of one Class A Director then in office shall terminate forthwith; provided, however, that the selection of which -------- ------- Class A Director's term of office shall terminate shall be at the discretion of a majority of holders of Class A Common Stock, and (ii) the conversion of all outstanding shares of Class A Common Stock pursuant to Section C.4 of this Article IV, the term of office of all Class A Directors then in office shall thereupon terminate. The vacancies resulting from any such termination pursuant to the preceding clauses (i) or (ii) shall be filled by the remaining Directors then in office acting by majority vote of such remaining Directors, though less than a quorum. The Directors so elected to fill such vacancies shall not be treated hereunder or under the By-laws of the Corporation as Class A Directors. (c) Replacement. Subject to Section C.2(b) of this Article IV, in ------------ the case of any vacancy occurring among the Class A Directors, the holders of Class A Common Stock then outstanding, voting separately as a class may, either by written consent or at a special meeting of such holders called in accordance with the By-laws of the Corporation, elect successors to hold office for the unexpired term(s) of the Director(s) whose place(s) shall be vacant. (d) Except as set forth in this Section C.2 of this Article IV, the holders of Class A Common Stock shall not be entitled to vote in respect of the election of Directors of the Corporation. 3. Certain Significant Actions. Subject to the terms and conditions ---------------------------- of the Governance Agreement, the Corporation shall not take any Significant Action (as such term is defined in the Governance Agreement) without the approval of the holders of a majority of the Class A Common Stock then outstanding, voting separately as a single class, either by written consent or at a special meeting of such holders called in accordance with the By-laws of the Corporation. 4. Conversion of Class A Common Stock. ----------------------------------- (a) Voluntary Conversion. Each share of Class A Common Stock shall --------------------- be convertible, at the option of its record holder, into one validly issued fully paid and non-assessable share of Common Stock at any time.

6 (b) Voluntary Conversion Procedure. At the time of a voluntary ------------------------------- conversion, the record holder of shares of Class A Common Stock shall deliver to the principal office of the Corporation or any transfer agent for shares of Common Stock (i) the certificate or certificates representing the shares of Class A Common Stock to be converted, duly endorsed in blank or accompanied by proper instruments of transfer and (ii) written notice to the Corporation stating that the record holder elects to convert such share or shares and stating the name or names (with addresses) and denominations in which the certificate or certificates representing the shares of Common Stock issuable upon the conversion are to be issued and including instructions for the delivery thereof. Conversion shall be deemed to have been effected at the time when delivery is made to the Corporation or its transfer agent of such written notice and the certificate or certificates representing the shares of Class A Common Stock to be converted, and as of such time each Person named in such written notice as the Person to whom a certificate representing shares of Common Stock is to be issued, shall be deemed to be the holder of record of the number of shares of Common Stock to be evidenced by that certificate. Upon such delivery, the Corporation or its transfer agent shall promptly issue and deliver at the stated address of such record holder of shares of Common Stock a certificate or certificates representing the number of shares of Common Stock to which such record holder is entitled by reason of such conversion, and shall cause such shares of Common Stock to be registered in the name of the record holder. (c) Automatic Conversion. (i) Subject to paragraph (iii) below, in --------------------- the event of any Transfer (as hereinafter defined) of any share of Class A Common Stock to any Person other than an Affiliate (as hereinafter defined) of the TDF Group in accordance with Section 7.08 of the Governance Agreement, such share of Class A Common Stock shall automatically, without any further action, convert into one share of Common Stock. (ii) Each share of Class A Common Stock shall automatically convert into one share of Common Stock on the first date on which the Ownership Interest of the TDF Group is less than 5%. (iii) Notwithstanding anything to the contrary set forth in this Section C of Article IV, a holder of shares of Class A Common Stock may pledge such holder's

7 shares of Class A Common Stock to a financial institution pursuant to a bona fide pledge of such shares of Class A Common Stock as collateral security for any indebtedness or other obligation of any Person (the "Pledged Stock") due to the pledgee or its nominee without any conversion of the Class A Common Stock into Common Stock; provided, however, that (A) -------- ------- such shares shall not be voted by or registered in the name of the pledgee and shall remain subject to the provisions of this Section C.4 and (B) upon any foreclosure, realization or other similar action by the pledgee, such Pledged Stock shall automatically convert into shares of Common Stock on a share for share basis unless all right, title and interest in such Pledged Stock shall be Transferred concurrently by the pledgee or the purchaser in such foreclosure to an Affiliate of such holder. (iv) The foregoing automatic conversion events described in this paragraph (c) shall be referred to hereinafter as "Events of Automatic Conversion." The determination of whether an Event of Automatic Conversion shall have occurred will be made by the Board of Directors in accordance with paragraph (h) below. (d) Automatic Conversion Procedure. Any conversion pursuant to an ------------------------------- Event of Automatic Conversion shall be deemed to have been effected at the time the Event of Automatic Conversion occurred (the "Conversion Time"). At the Conversion Time, the certificate or certificates that represented immediately prior thereto the shares of Class A Common Stock which were so converted (the "Converted Class A Common Stock") shall, automatically and without further action, represent the same number of shares of Common Stock. Holders of Converted Class A Common Stock shall deliver their certificates, duly endorsed in blank or accompanied by proper instruments of transfer, to the principal office of the Corporation or the office of any transfer agent for shares of the Common Stock, together with a notice setting out the name or names (with addresses) and denominations in which the certificate or certificates representing such shares of Common Stock are to be issued and including instructions for delivery thereof. Upon such delivery, the Corporation or its transfer agent shall promptly issue and deliver at such stated address to such holder of shares of Common Stock a certificate or certificates representing the number of shares of Common Stock to which such holder is entitled by reason of such conversion. The Person entitled to

8 receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder of such shares of Common Stock at and as of the Conversion Time, and the rights of such Person as a holder of shares of Class A Common Stock that have been converted shall cease and terminate at and as of the Conversion Time, in each case without regard to any failure by such holder to deliver the certificates or the notice required by this Section. (e) Unconverted Shares; Notice Required. In the event of the ------------------------------------ conversion of less than all the shares of Class A Common Stock evidenced by a certificate surrendered to the Corporation in accordance with the procedures of this Section C.4, the Corporation shall execute and deliver to or upon the written order of the holder of such unconverted shares, without charge to such holder, a new certificate evidencing the number of shares of Class A Common Stock not converted. (f) Retired Shares. Shares of Class A Common Stock that are --------------- converted into shares of Common Stock as provided herein shall not be re- issued as shares of Class A Common Stock and shall be retired and canceled. (g) Reservation. The Corporation shall at all times reserve and keep ------------ available, out of its authorized and unissued shares of Common Stock, for the purposes of effecting conversions, such number of duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Class A Common Stock. All the shares of Common Stock so issuable shall, when so issued, be duly and validly issued, fully paid and non-assessable, and free from liens and charges with respect to such issuance. (h) Determination of Voting Rights and Events of Automatic ------------------------------------------------------ Conversion. The Board of Directors of the Corporation shall have the power ----------- to determine by a two-thirds vote of the entire Board of Directors, in good faith after reasonable inquiry, whether an Event of Automatic Conversion has occurred with respect to any share of Class A Common Stock. As a condition to counting the votes cast by any holder of shares of Class A Common Stock at any annual or special meeting of shareholders or as a condition to registration of transfer of shares of Class A Common Stock, or for any other purpose, the Board of Directors, in its discretion, may require the holder of such shares to furnish such affidavits or other proof as the Board of

9 Directors reasonably deems necessary or advisable to determine whether an Event of Automatic Conversion shall have occurred. (i) Stock Legend. The Corporation shall include on the certificates ------------- representing the shares of Class A Common Stock a conspicuous legend referring to the restrictions on transfer and registration of transfer imposed by this Section C.4. (j) Taxes. The issuance of a certificate for shares of Common Stock ------ upon conversion of shares of Class A Common Stock shall be made without charge for any stamp or other similar tax in respect of such issuance. However, if any such certificate is to be issued in a name other than that of the holder of the shares of Class A Common Stock converted, the Person or Persons requesting the issuance thereof shall pay to the Corporation the amount of any tax which may be payable in respect of any Transfer involved in such issuance or shall establish to the satisfaction of the Corporation that such tax has been paid or is not required to be paid. 5. Certain Adjustments.

ARTICLE V By-laws ------- In furtherance of, and not in limitation of, the powers conferred by law and subject to the other provisions of this Restated Certificate of Incorporation and subject to Article IX of the Amended and Restated By-laws of the Corporation, the Board of Directors is expressly authorized and empowered: (1) To adopt, amend or repeal the By-laws of the Corporation; provided, however, that the By-laws adopted by the Board of Directors under -------- ------- the powers hereby conferred may be amended or repealed by the

12 Board of Directors or by the stockholders having voting power with respect thereto, provided further that the affirmative vote of the holders of at least 80% of the voting power of the then outstanding Voting Stock (as hereinafter defined), voting together as a single class, shall be required in order for the stockholders to alter, amend or repeal any provision of the By-laws or to adopt any additional By-law; and (2) from time to time to determine whether and to what extent, and at what times and places, and under what conditions and regulations, the accounts and books of the Corporation, or any of them, shall be open to inspection of stockholders; and, except as so determined or as expressly provided in this Restated Certificate of Incorporation or in any Preferred Stock Designation, no stockholder shall have any right to inspect any account, book or document of the Corporation other than such rights as may be conferred by applicable law. The Corporation may in its By-laws confer powers upon the Board of Directors in addition to the foregoing and in addition to the powers and authorities expressly conferred upon the Board of Directors by applicable law. ARTICLE VI Action of Stockholders ---------------------- Except as otherwise specified with respect to any series of Preferred Stock and the Class A Common Stock, any action required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders of the Corporation and may not be effected by any consent in writing in lieu of a meeting of such stockholders. ARTICLE VII Board of Directors ------------------ Subject to the rights of the holders of any series of Preferred Stock to elect additional Directors under specified circumstances, the number of Directors of the Corporation shall initially be 12 (including the two Directors to be elected by the holders of the Class A Common Stock) and may hereafter be changed from time to time solely by the Board of Directors.

13 Unless and except to the extent that the By-laws of the Corporation shall so require, the election of Directors of the Corporation need not be by written ballot. The Directors, other than those Directors who may be elected by the holders of any series of Preferred Stock or holders of Class A Common Stock (the "Non-Classified Directors"), shall be divided into three classes, as nearly equal in number as possible, initially consisting of 3, 3 and 4 Directors. One class of Directors initially consisting of 3 Directors shall be initially elected for a term expiring at the annual meeting of stockholders to be held in 1999, another class initially consisting of 3 Directors shall be initially elected for a term expiring at the annual meeting of stockholders to be held in 2000, and another class initially consisting of 4 Directors shall be initially elected for a term expiring at the annual meeting of stockholders to be held in 2001. Upon the termination of the term of any Class A Director or Directors then in office pursuant to Section C.2(b) or Section C.4 of Article IV, the number of Directors in one or both, as applicable, of the classes consisting of three Directors shall be increased by one such that the three classes of Directors shall consist of 3, 4 and 4 Directors, or 4, 4 and 4 Directors, as applicable. Members of each class shall hold office until their successors are elected and qualified. At each annual meeting of the stockholders of the Corporation commencing with the 1999 annual meeting, Directors (other than Non- Classified Directors) elected to succeed those Directors whose terms expire shall be elected by a plurality vote at such meeting to hold office for a term expiring at the third succeeding annual meeting of stockholders after their election, with each Director to hold office until his or her successor shall have been duly elected and qualified. Subject to the rights of the holders of any series of Preferred Stock or holders of Class A Common Stock, vacancies resulting from death, resignation, retirement, disqualification, removal from office or other cause, and newly created Directorships resulting from any increase in the authorized number of Directors, may be filled only by the affirmative vote of a majority of the remaining Directors, though less than a quorum of the Board of Directors, and Directors so chosen shall hold office for a term expiring at the next annual meeting of stockholders at which the term of office of the class to which they have been elected expires and until such Director's successor shall have been duly elected and qualified. No decrease in the number of authorized Directors constituting the Board of Directors shall shorten the term of any incumbent Director.

14 Except for such additional Directors, if any, as are elected by the holders of any series of Preferred Stock or holders of Class A Common Stock, any Director may be removed from office at any time, but only for cause and by the affirmative vote of the holders of at least 80 percent of the voting power of the then outstanding Voting Stock (other than the Class A Common Stock), voting together as a single class. Notwithstanding the foregoing, holders of Class A Common Stock, voting separately as a class, either by written consent or at a special meeting of such holders called in accordance with the By-laws of the Corporation, may remove any Class A Director with or without cause. ARTICLE VIII Indemnification --------------- Each person who is or was a Director or officer of the Corporation shall be indemnified by the Corporation to the fullest extent permitted by the General Corporation Law of the State of Delaware as the same exists or may hereafter be amended or any other applicable laws as presently or hereafter in effect. The Corporation may, by action of the Board of Directors, provide indemnification to other employees and agents of the Corporation, to directors, officers, employees or agents of a subsidiary, and to each person serving as a director, officer, partner, member, employee or agent of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, at the request of the Corporation, with the same scope and effect as the foregoing indemnification of Directors and officers of the Corporation. Notwithstanding the foregoing, the Corporation shall be required to indemnify any person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board of Directors or is a proceeding to enforce such person's claim to indemnification pursuant to the rights granted by this Restated Certificate of Incorporation or otherwise by the Corporation. Without limiting the generality of the effect of the foregoing, the Corporation may enter into one or more agreements with any person which provide for indemnification greater or different than that provided in this Article VIII. Any amendment or repeal of this Article VIII shall not adversely affect any right or protection existing hereunder in respect of any act or omission occurring prior to such amendment or repeal.

15 ARTICLE IX Directors' Liability -------------------- A Director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a Director, except for liability (1) for any breach of the Director's duty of loyalty to the Corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the General Corporation Law of the State of Delaware, or (4) for any transaction from which the Director derived an improper personal benefit. Any amendment or repeal of this Article IX shall not adversely affect any right or protection of a Director of the Corporation existing hereunder in respect of any act or omission occurring prior to such amendment or repeal. If the General Corporation Law of the State of Delaware shall be amended, to authorize corporate action further eliminating or limiting the liability of Directors, then a Director of the Corporation, in addition to the circumstances in which he is not liable immediately prior to such amendment, shall be free of liability to the fullest extent permitted by the General Corporation Law of the State of Delaware, as so amended. ARTICLE X Stockholder Rights Issuances ---------------------------- The Board of Directors is hereby authorized to create and issue, whether or not in connection with the issuance and sale of any of its stock or other securities or property, rights entitling the holders of securities of the Corporation to purchase from the Corporation shares of stock or other securities of the Corporation or any other corporation, recognizing that, under certain circumstances, the creation and issuance of such rights could have the effect of discouraging third parties from seeking, or impairing their ability to seek, to acquire a significant portion of the outstanding securities of the Corporation, to engage in any transaction which might result in a change of control of the Corporation or to enter into any agreement, arrangement or understanding with another party to accomplish the foregoing or for the purpose of acquiring, holding, voting or disposing of any securities of the Corporation. The times at which and the terms upon which such rights are to be issued will be determined by the Board of Directors and set forth in the contracts or instruments

16 that evidence such rights. The authority of the Board of Directors with respect to such rights shall include, but not be limited to, determination of the following: (A) The initial purchase price per share or other unit of the stock or other securities or property to be purchased upon exercise of such rights. (B) Provisions relating to the times at which and the circumstances under which such rights may be exercised or sold or otherwise transferred, either together with or separately from, any other stock or other securities of the Corporation. (C) Provisions which adjust the number or exercise price of such rights or amount or nature of the stock or other securities or property receivable upon exercise of such rights in the event of a combination, split or recapitalization of any stock of the Corporation, a change in ownership of the Corporation's stock or other securities or a reorganization, merger, consolidation, sale of assets or other occurrence relating to the Corporation or any stock of the Corporation, and provisions restricting the ability of the Corporation to enter into any such transaction absent an assumption by the other party or parties thereto of the obligations of the Corporation under such rights. (D) Provisions which deny the holder of the specified percentage of the outstanding stock or other securities of the Corporation the right to exercise such rights and/or cause the rights held by such holder to become void. (E) Provisions which permit the Corporation to redeem or exchange such rights, which redemption or exchange may be within the sole discretion of the Board of Directors, if the Board of Directors reserves such right to itself. (F) The appointment of the rights agent with respect to such rights. Notwithstanding anything contained in this Restated Certificate of Incorporation to the contrary, in addition to any other vote required by applicable law, the affirmative vote of at least 80 percent of the voting power of the then outstanding Voting Stock, voting together as a single class, shall be required to amend, repeal or adopt any provision inconsistent with this Article X.

17 ARTICLE XI Other Agreements ---------------- Notwithstanding any other provision of this Restated Certificate of Incorporation, to the extent any provision of the Stockholders Agreement (attached as Exhibit B) or the Governance Agreement (attached as Exhibit A), conflict with, modify or alter any provision of this Restated Certificate of Incorporation, such provision of the Stockholders Agreement or of the Governance Agreement shall control and be deemed incorporated as part of this Restated Certificate of Incorporation. ARTICLE XII Amendments ---------- Except as may be expressly provided in this Restated Certificate of Incorporation, the Corporation reserves the right at any time and from time to time to amend, alter, change or repeal any provision contained in this Restated Certificate of Incorporation or a Preferred Stock Designation, and any other provisions authorized by the laws of the State of Delaware at the time in force may be added or inserted, in the manner now or hereafter prescribed herein or by applicable law, and all rights, preferences and privileges of whatsoever nature conferred upon stockholders, Directors or any other persons whomsoever by and pursuant to this Restated Certificate of Incorporation in its present form or as hereafter amended are granted subject to the right reserved in this Article XII; provided, however, that any amendment or repeal of Article VIII or Article IX of - -------- ------- this Restated Certificate of Incorporation shall not adversely affect any right or protection existing thereunder in respect of any act or omission occurring prior to such amendment, alteration, change or repeal, and provided further that no Preferred Stock Designation shall be amended after the issuance of any shares of the series of Preferred Stock created thereby, except in accordance with the terms of such Preferred Stock Designation and the requirements of applicable law. Notwithstanding anything contained in this Restated Certificate of Incorporation to the contrary, and in addition to approval by the Board of Directors and any other vote of stockholders required by applicable law, the affirmative vote of the holders of at least 80% of the voting power of the then outstanding Voting Stock, voting

18 together as a single class, shall be required to amend, repeal or adopt any provision inconsistent with paragraph (1) of Article V, Article VI, Article VII, Article X, Article XI or this second paragraph of this Article XII; provided, -------- however, that, in addition to approval by the Board of Directors and any other - ------- vote of stockholders required by applicable law, any such amendment to Article XI or the provisions of this second paragraph of this Article XII with respect to such Article XI shall, in addition, require the approval of a majority of the holders the Class A Common Stock then outstanding, voting as a separate class. For the purposes of this Restated Certificate of Incorporation, "Voting Stock" shall mean the outstanding shares of capital stock of the Corporation entitled to vote in a general vote of stockholders of the Corporation as a single class with shares of Common Stock of the Corporation, which shares of capital stock shall be deemed to include the Class A Common Stock. Notwithstanding the foregoing, no amendment to this Restated Certificate of Incorporation which adversely affects the rights of the holders of the Class A Common Stock may be effected without the approval of the holders of a majority of the Class A Common Stock then outstanding. IN WITNESS WHEREOF, the undersigned has executed this Restated Certificate of Incorporation on this 21st day of August, 1998. CROWN CASTLE INTERNATIONAL CORP.

To the extent that the provisions of any such securities laws or securities regulations conflict with this Section 8.1, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 8.1 by virtue thereof. The Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Certificate of Designations applicable to a Change of Control Offer made by the Company and purchases all Senior Exchangeable Preferred Stock validly tendered and not withdrawn under such Change of Control Offer. Notwithstanding the foregoing, the Company may not repurchase any Senior Exchangeable Preferred Stock pursuant to this provision unless such repurchase complies with the restricted payments covenant contained in the Senior Discount Notes Indenture; provided that if the Company does not make a Change of Control Offer or does not repurchase any Senior Exchangeable Preferred Stock pursuant to a Change of Control Offer, then such failure shall constitute a Voting Rights Triggering Event. Section 8.2 Asset Sales The Company shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: (1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value (evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the Transfer Agent) of the assets or Equity Interests issued or sold or otherwise disposed of; and 26

(2) except in the case of a Tower Asset Exchange, at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash: (1) any liabilities (as shown on the Company's or such Restricted Subsidiary's most recent balance sheet), of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Senior Exchangeable Preferred Stock or any guarantee thereof) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability; and (2) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 20 days of the applicable Asset Sale (to the extent of the cash received). Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or the applicable Restricted Subsidiary may apply such Net Proceeds to: (1) reduce any Indebtedness of the Company; (2) reduce any Indebtedness of any of the Company's Restricted Subsidiaries; (3) the acquisition of all or substantially all the assets of a Permitted Business; (4) the acquisition of Voting Stock of a Permitted Business from a Person that is not a Subsidiary of the Company; provided, that, after giving effect thereto, the Company or its Restricted Subsidiary owns a majority of such Voting Stock and designates such Permitted Business as a Restricted Subsidiary or (5) the making of a capital expenditure or the acquisition of other long-term assets that are used or useful in a Permitted Business. Pending the final application of any such Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest such Net Proceeds in any manner that is not prohibited by this Certificate of Designations. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the first sentence of this paragraph shall be deemed to constitute "Excess Proceeds". When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company shall be required to make an offer to all holders of Senior Discount Notes and may be required to make such offer to holders of other Indebtedness of the Company then outstanding (a "Senior Asset Sale Offer") to ----------------------- purchase the maximum principal amount of the Senior Discount Notes and such other Indebtedness, if applicable, that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount or accreted value thereof, as the case may be, plus accrued and unpaid interest to the date of purchase, in accordance with the procedures set forth in the Senior Discount Notes Indenture and in the instruments governing such other Indebtedness. To the extent that the aggregate amount of Senior Discount Notes and such other Indebtedness tendered pursuant to a Senior Asset Sale Offer is less than the remaining 27

Excess Proceeds ("Remaining Excess Proceeds") and the sum of (A) such amount of ------------------------- Remaining Excess Proceeds and (B) the Remaining Excess Proceeds from any subsequent Senior Asset Sale Offers exceeds $3.0 million, the Company shall be required to make an offer to all Holders of Senior Exchangeable Preferred Stock and all holders of Parity Securities containing provisions similar to those set forth in this Certificate of Designations with respect to offers to purchase with the proceeds of sales of assets (an "Asset Sale Offer") to purchase the ---------------- maximum Liquidation Preference of Senior Exchangeable Preferred Stock and such Parity Securities that may be purchased out of such Remaining Excess Proceeds, at an offer price in cash in an amount equal to 100% of the Liquidation Preference thereof plus accrued and unpaid dividends and Liquidated Damages thereon, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive dividends and Liquidated Damages, if any, due on the relevant Dividend Payment Date), in accordance with the procedures set forth in this Certificate of Designations and such Parity Securities. To the extent that any Remaining Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by this Certificate of Designations. If the aggregate Liquidation Preference of Senior Exchangeable Preferred Stock and such Parity Securities tendered into such Asset Sale Offer surrendered by Holders thereof exceeds the amount of Remaining Excess Proceeds, the Transfer Agent shall select the Senior Exchangeable Preferred Stock and such Parity Securities to be purchased on a pro rata basis. Upon completion of such offer to purchase, the amount of Excess Proceeds shall be reset at zero. The Asset Sale provisions described above shall be applicable whether or not any other provisions of this Certificate of Designations are applicable. The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations applicable to any Asset Sale Offer. To the extent that the provisions of any such securities laws or securities regulations conflict with the provisions of this Section 8.2, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 8.2 by virtue thereof. Notwithstanding the foregoing, the Company may not repurchase any Senior Exchangeable Preferred Stock pursuant to this provision unless such repurchase complies with the restricted payments covenant contained in the Senior Discount Notes Indenture; provided that if the Company does not make an Asset Sale Offer or does not repurchase any Senior Exchangeable Preferred Stock pursuant to an Asset Sale Offer, then such failure shall constitute a Voting Rights Triggering Event. SECTION 9 CERTAIN COVENANTS Section 9.1 Restricted Payments The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly: (1) declare or pay any dividend or make any other payment or distribution on account of the Company's Junior Securities or any warrants, options or other rights to acquire Junior Securities (other than any debt security that is convertible into, or exchangeable for, Junior Securities) or any of the Company's Restricted Subsidiaries' Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company's Junior Securities or any warrants, options or other rights to acquire Junior Securities (other than any debt security that is convertible into, or exchangeable for, Junior Securities) or any of the 28

Company's Restricted Subsidiaries' Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or to the Company or a Restricted Subsidiary of the Company); (2) purchase, redeem or otherwise acquire or retire for value (including without limitation, in connection with any merger or consolidation involving the Company) any Junior Securities of the Company or any warrants, options or other rights to acquire Junior Securities (other than any debt security that is convertible into, or exchangeable for, Junior Securities) or any Equity Interests of any direct or indirect parent of the Company (other than any such Equity Interests owned by the Company or any Restricted Subsidiary of the Company and other than the Senior Exchangeable Preferred Stock); or (3) make any Restricted Investment, (all such payments and other actions set forth in clauses (1) through (3) above being collectively referred to as "Restricted Payments"), unless, at the time of and after giving effect to such Restricted Payment: (1) no Voting Rights Triggering Event shall have occurred and be continuing or would occur as a consequence thereof; and (2) the Company would have been permitted to incur at least $1.00 of additional indebtedness pursuant to the Debt to Adjusted Consolidated Cash Flow Ratio test set forth in the first paragraph of Section 9.2 hereof; provided that the Company and its Restricted Subsidiaries shall not be required to comply with this clause (2) in order to make any Restricted Investment; and (3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (2) and (3) of the next succeeding paragraph), is less than the sum, without duplication, of: (a) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from the beginning of the first fiscal quarter commencing after the Issue Date to the end of the Company's most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus (b) 100% of the aggregate net cash proceeds received by the Company since the Issue Date as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Company (other than Disqualified Stock and except to the extent such net cash proceeds are used to incur new Indebtedness outstanding pursuant to clause (10) of the second paragraph of Section 9.2 hereof) or from the issue or sale of Disqualified Stock or debt securities of the Company that have been converted into such Equity Interests (other than Equity Interests (or Disqualified Stock or convertible debt securities) sold to a Subsidiary of the Company and other than Disqualified Stock or convertible debt securities that have been converted into Disqualified Stock); plus 29

(c) to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or otherwise liquidated or repaid for cash, the lesser of (A) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (B) the initial amount of such Restricted Investment; plus (d) to the extent that any Unrestricted Subsidiary of the Company and all of its Subsidiaries are designated as Restricted Subsidiaries after the Issue Date, the lesser of (A) the fair market value of the Company's Investments in such Subsidiaries as of the date of such designation, or (B) the sum of (x) the fair market value of the Company's Investments in such Subsidiaries as of the date on which such Subsidiaries were originally designated as Unrestricted Subsidiaries and (y) the amount of any Investments made in such Subsidiaries subsequent to such designation (and treated as Restricted Payments) by the Company or any Restricted Subsidiary; provided that: (i) in the event the Unrestricted Subsidiaries designated as Restricted Subsidiaries are CTSH and its Subsidiaries, the references in clauses (A) and (B) of this clause (d) to fair market value of the Company's Investments in such Subsidiaries shall mean the amount by which the fair market value of all such Investments exceeds 34.3% of the fair market value of CTSH and its Subsidiaries as a whole; and (ii) in the event the Unrestricted Subsidiaries designated as Restricted Subsidiaries are CCAIC and its Subsidiaries, the references in clauses (A) and (B) of this clause (d) to fair market value of the Company's Investments in such Subsidiaries shall mean the amount by which the fair market value of all such Investments exceeds $250.0 million; plus (e) 50% of any dividends received by the Company or a Restricted Subsidiary after the Issue Date from an Unrestricted Subsidiary of the Company, to the extent that such dividends were not otherwise included in Consolidated Net Income of the Company for such period. The foregoing provisions shall not prohibit: (1) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of this Certificate of Designations; (2) the making of any Investment or the redemption, repurchase, retirement, defeasance or other acquisition of any Equity Interests of the Company in exchange for, or out of the net cash proceeds of the sale after the Issue Date (other than to a Subsidiary of the Company) of, any Equity Interests of the Company (other than any Disqualified Stock), provided that such net cash proceeds are not used to incur new Indebtedness pursuant to clause (10) of the second paragraph of Section 9.2 hereof); and provided further that, in each such case, the amount of any such net cash proceeds that are so utilized shall be excluded from clause (3) (b) of the preceding paragraph; (3) the payment of any dividend by a Restricted Subsidiary of the Company to the holders of its Equity Interests on a pro rata basis; or 30

(4) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any member of the Company's (or any of its Restricted Subsidiaries') management pursuant to any management equity subscription agreement or stock option agreement in effect as of the Issue Date; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed (a) $500,000 in any twelve-month period and (b) $5.0 million in the aggregate. The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a Voting Rights Triggering Event; provided that in no event shall the businesses operated by the Company's Restricted Subsidiaries as of November 20, 1997 be transferred to or held by an Unrestricted Subsidiary. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated shall be deemed to be Restricted Payments at the time of such designation and shall reduce the amount available for Restricted Payments under the first paragraph of this Section 9.1. All such outstanding Investments shall be deemed to constitute Investments in an amount equal to the fair market value of such Investments at the time of such designation. Such designation shall only be permitted if such Restricted Payment would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may designate any Unrestricted Subsidiary to be a Restricted Subsidiary if such designation would not cause a Voting Rights Triggering Event. The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or the applicable Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any property, assets or Investments required by this Section 9.1 to be determined shall be determined by the Board of Directors whose resolution with respect thereto shall be delivered to the Transfer Agent. Section 9.2 Incurrence of Indebtedness and Issuance of Preferred Stock The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, "incur") any Indebtedness (including Acquired Debt) and that the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, that the Company may incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock and the Company's Restricted Subsidiaries may incur Indebtedness if, in each case, the Company's Debt to Adjusted Consolidated Cash Flow Ratio at the time of incurrence of such Indebtedness or the issuance of such Disqualified Stock, after giving pro forma effect to such incurrence or issuance as of such date and to the use of proceeds therefrom as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been no greater than 7.5 to 1. The provisions of the first paragraph of this Section 9.2 shall not apply to the incurrence of any of the following items of Indebtedness or to the issuance of any of the following items of Disqualified Stock or preferred stock (collectively, "Permitted Debt"): 31

(1) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness (including Indebtedness under Credit Facilities) in an aggregate principal amount (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) at any one time outstanding not to exceed the greater of (x) $200.0 million less the aggregate amount of all Net Proceeds of Asset Sales applied to repay Indebtedness under a Credit Facility pursuant to Section 8.2 hereof, and (y) 70% of the Eligible Receivables that are outstanding as of such date of incurrence; (2) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness; (3) the issuance by the Company of preferred stock represented by the Senior Exchangeable Preferred Stock and the incurrence by the Company of Indebtedness represented by the Senior Subordinated Exchange Debentures; (4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Company or such Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any other Indebtedness incurred pursuant to this clause (4), not to exceed $10.0 million at any one time outstanding; (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund Indebtedness of the Company or any of its Restricted Subsidiaries or Disqualified Stock of the Company (other than intercompany Indebtedness) that was permitted by this Certificate of Designations to be incurred under the first paragraph hereof or clauses (2) or (3) or this clause (5) of this paragraph; (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, that (A) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (B) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be; (7) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing or hedging interest rate risk with respect to any floating rate Indebtedness that is permitted by the terms of this Certificate of Designations to be outstanding or currency exchange risk; (8) the guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of this Certificate of Designations; 32

(9) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt in connection with the acquisition of assets or a new Subsidiary and the incurrence by the Company's Restricted Subsidiaries of Indebtedness as a result of the designation of an Unrestricted Subsidiary as a Restricted Subsidiary; provided that, in the case of any such incurrence of Acquired Debt, such Acquired Debt was incurred by the prior owner of such assets or such Restricted Subsidiary prior to such acquisition by the Company or one of its Restricted Subsidiaries and was not incurred in connection with, or in contemplation of, such acquisition by the Company or one of its Restricted Subsidiaries; and provided further that, in the case of any incurrence pursuant to this clause (9), as a result of such acquisition by the Company or one of its Restricted Subsidiaries, the Company's Debt to Adjusted Consolidated Cash Flow Ratio at the time of incurrence of such Acquired Debt, after giving pro forma effect to such incurrence as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been less than the Company's Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such incurrence; (10) the incurrence by the Company of Indebtedness not to exceed, at any one time outstanding, the sum of (i) 2.0 times the aggregate net cash proceeds plus (ii) 1.0 times the fair market value of non-cash proceeds (evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the Transfer Agent), in each case, from the issuance and sale, other than to a Subsidiary, of Equity Interests (other than Disqualified Stock) of the Company since the Issue Date (less the amount of such proceeds used to make Restricted Payments as provided in clause (3)(b) of the first paragraph or clause (2) of the second paragraph of Section 9.1 hereof); provided that such Indebtedness does not mature prior to the Stated Maturity of the Senior Exchangeable Preferred Stock and the Weighted Average Life to Maturity of such Indebtedness is longer than that of the Senior Exchangeable Preferred Stock; and (11) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness and/or the issuance by the Company of Disqualified Stock in an aggregate principal amount, accreted value or liquidation preference, as applicable, at any time outstanding, not to exceed an amount equal to $100.0 million less the aggregate amount of all Investments made pursuant to clause (12) of the definition of Permitted Investments; provided that, notwithstanding the foregoing, the aggregate principal amount, accreted value or liquidation preference, as applicable, permitted to be incurred or issued pursuant to this clause (11) shall not be reduced to less than $25.0 million. For purposes of determining compliance with this Section 9.2, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (11) above or is entitled to be incurred pursuant to the first paragraph of this Section 9.2, the Company shall, in its sole discretion, classify (or later reclassify in whole or in part) such item of Indebtedness in any manner that complies with this Section 9.2. Accrual of interest, accretion or amortization of original issue discount and the payment of interest in the form of additional Indebtedness shall not be deemed to be an incurrence of Indebtedness for purposes of this Section 9.2. Section 9.3 Dividend and Other Payment Restrictions Affecting Subsidiaries The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to 33

(1) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries on its Capital Stock or with respect to any other interest or participation in, or measured by, its profits; (2) pay any indebtedness owed to the Company or any of its Restricted Subsidiaries; (3) make loans or advances to the Company or any of its Restricted Subsidiaries; or (4) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries. However, the foregoing restrictions shall not apply to encumbrances or restrictions existing under or by reason of: (1) Existing Indebtedness or Indebtedness under the Senior Credit Facility, in each case as in effect on the Issue Date, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in the applicable series of Existing Indebtedness or in the Senior Credit Facility, in each case as in effect on the Issue Date; (2) encumbrances and restrictions applicable to any Unrestricted Subsidiary, as the same are in effect as of the date on which such Subsidiary becomes a Restricted Subsidiary, and as the same may be amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in the applicable series of Indebtedness of such Subsidiary as in effect on the date on which such Subsidiary becomes a Restricted Subsidiary; (3) any Indebtedness (incurred in compliance with Section 9.2 hereof) or any agreement pursuant to which such Indebtedness is issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant contained in such Indebtedness or agreement and such encumbrance or restriction is not materially more disadvantageous to the holders of the Senior Exchangeable Preferred Stock than is customary in comparable financings (as determined by the Company) and the Company determines that any such encumbrance or restriction will not materially affect the Company's ability to pay dividends or the Liquidation Preference on the Senior Exchangeable Preferred Stock; (4) this Certificate of Designations; (5) applicable law; (6) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so 34

acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Certificate of Designations to be incurred; (7) by reason of customary non-assignment provisions in leases or licenses entered into in the ordinary course of business; (8) purchase money obligations for property acquired in the ordinary course of business that impose restrictions of the nature described in clause (4) in the prior paragraph on the property so acquired; (9) the provisions of agreements governing Indebtedness incurred pursuant to clause (4) of the second paragraph of Section 9.2 hereof; (10) any agreement for the sale of a Restricted Subsidiary that restricts that Restricted Subsidiary pending its sale; (11) Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; (12) Liens that limit the right of the debtor to transfer the assets subject to such Liens; (13) provisions with respect to the disposition or distribution of assets or property in joint venture agreements and other similar agreements and (14) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business. Section 9.4 Merger, Consolidation or Sale of Assets The Company may not consolidate or merge with or into (whether or not the Company is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to another corporation, Person or entity unless: (1) the Company is the surviving corporation or the entity or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia; (2) the entity or Person formed by or surviving any such consolidation or merger (if other than the Company) or the entity or Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Senior Exchangeable Preferred Stock and this Certificate of Designations; (3) immediately after such transaction no Voting Rights Triggering Event exists; and 35

(4) except in the case of a merger of the Company with or into a Wholly Owned Restricted Subsidiary of the Company and except in the case of a merger entered into solely for the purpose of reincorporating the Company in another jurisdiction, (a) in the case of a merger or consolidation in which the Company is the surviving corporation, the Company's Debt to Adjusted Consolidated Cash Flow Ratio, at the time of such transaction after giving pro forma effect thereto as if such transaction had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been less than the Company's Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such transaction, or (b) in the case of any other such transaction the Debt to Adjusted Consolidated Cash Flow of the entity or Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made, at the time of such transaction after giving pro forma effect thereto as if such transaction had occurred at the beginning of the most recently ended four full fiscal quarter period of such entity or Person for which internal financial statements are available, would have been less than the Company's Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such transaction; provided that for purposes of determining the Debt to Adjusted Consolidated Cash Flow Ratio of any such entity or Person for purposes of this clause (b) such entity or Person shall be substituted for the Company in the definition of Debt to Adjusted Consolidated Cash Flow Ratio and the defined terms included therein in Section 1 hereof. Section 9.5 Transactions with Affiliates The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless: (1) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and (2) the Company delivers to the Transfer Agent: (a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $1.0 million, a resolution of the Board of Directors set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with clause (i) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors; and (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, an opinion as 36

to the fairness to the Holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. The following items shall not be deemed to be Affiliate Transactions and therefore shall not be subject to the provisions of the prior paragraph: (1) any employment arrangements with any executive officer of the Company or a Restricted Subsidiary that is entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and consistent with compensation arrangements of similarly situated executive officers at comparable companies engaged in Permitted Businesses; (2) transactions between or among the Company and/or its Restricted Subsidiaries; (3) payment of directors fees in an aggregate annual amount not to exceed $25,000 per Person; (4) Restricted Payments that are permitted by the provisions of this Certificate of Designations under Section 9.1 hereof; (5) the issuance or sale of Equity Interests (other than Disqualified Stock) of the Company; and (6) transactions pursuant to the provisions of the Governance Agreement, the Rights Agreement, the Stockholders' Agreement, the CTSH Shareholders' Agreement, the CTI Services Agreement, the CTI Operating Agreement and the Crown Transition Agreements, as the same are in effect on the Issue Date.

Section 9.7 Senior Subordinated Debt So long as any Senior Exchangeable Preferred Stock is outstanding, the Company shall not incur any Indebtedness, other than the Senior Subordinated Exchange Debentures and New Exchange Debentures, that is expressly made subordinated in right of payment to any Senior Debt unless such Indebtedness, by its terms and by the terms of any agreement or instrument pursuant to which such Indebtedness is outstanding, is expressly made pari passu with, or subordinate in right of payment to, the Senior Subordinated Exchange Debentures pursuant to provisions substantially similar to those contained in the Exchange Indenture; provided that the foregoing limitations shall not apply to distinctions between categories of Senior Debt that exist by reason of any Liens or Guarantees arising or created in respect of some but not all Senior Debt. Section 9.8 Business Activities The Company shall not, and shall not permit any Subsidiary to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Company and its Subsidiaries taken as a whole. Section 9.9 Reports Whether or not required by the rules and regulations of the Securities and Exchange Commission (the "Commission"), so long as any Senior Exchangeable Preferred Stock is outstanding, the Company shall furnish to the Holders of Senior Exchangeable Preferred Stock: (1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries (showing in reasonable detail, in the footnotes to the financial statements and in "Management's Discussion and Analysis of Financial Condition and Results of Operations" (in each case to the extent not prohibited by the Commission's rules and regulations), (a) the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company and (b) the Tower Cash Flow for the most recently completed fiscal quarter and the Adjusted Consolidated Cash Flow for the most recently completed four-quarter period) and, with respect to the annual information only, a report thereon by the Company's certified independent accountants; and (2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports, in each case within the time periods specified in the Commission's rules and regulations. In addition, following the consummation of the exchange offer contemplated by the Registration Rights Agreement, whether or not required by the rules and regulations of the Commission, the Company shall file a copy of all such information and reports with the Commission for public availability within the time periods specified in the Commission's rules and regulations (unless the Commission will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. 38

SECTION 10 AMENDMENT, SUPPLEMENT AND WAIVER Except as provided in the next two succeeding paragraphs, this Certificate of Designations or the Senior Exchangeable Preferred Stock may be amended or supplemented with the consent of the Holders of at least a majority in aggregate Liquidation Preference of the Senior Exchangeable Preferred Stock then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Senior Exchangeable Preferred Stock), and any existing default or compliance with any provision of this Certificate of Designations or the Senior Exchangeable Preferred Stock may be waived with the consent of the Holders of a majority in aggregate Liquidation Preference of the then outstanding Senior Exchangeable Preferred Stock (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Senior Exchangeable Preferred Stock). Without the consent of each Holder affected, an amendment or waiver may not (with respect to any shares of Senior Exchangeable Preferred Stock held by a non-consenting Holder): (1) alter the voting rights with respect to the Senior Exchangeable Preferred Stock or reduce the number of shares of Senior Exchangeable Preferred Stock whose Holders must consent to an amendment, supplement or waiver; (2) reduce the Liquidation Preference of or change the Mandatory Redemption Date of any Senior Exchangeable Preferred Stock or alter the provisions with respect to the redemption (but not any required repurchase in connection with an Asset Sale Offer or Change of Control Offer) of the Senior Exchangeable Preferred Stock; (3) reduce the rate of or change the time for payment of dividends on any Senior Exchangeable Preferred Stock; (4) waive a default in the payment of dividends on the Senior Exchangeable Preferred Stock; (5) make any Senior Exchangeable Preferred Stock payable in any form or money other than that stated in this Certificate of Designations; (6) waive a redemption payment (but not any payment upon a required repurchase in connection with an Asset Sale Offer or Change of Control Offer) with respect to any Senior Exchangeable Preferred Stock, or (7) make any change in the foregoing amendment and waiver provisions. Notwithstanding the foregoing, without the consent of any Holder of Senior Exchangeable Preferred Stock, the Company may (to the extent permitted by Delaware law) amend or supplement this Certificate of Designations: (1) to cure any ambiguity, defect or inconsistency; (2) to provide for uncertificated Senior Exchangeable Preferred Stock in addition to or in place of certificated Senior Exchangeable Preferred Stock; 39

(3) to provide for the assumption of the Company's obligations to Holders of Senior Exchangeable Preferred Stock in the case of a merger or consolidation or (4) to make any change that would provide any additional rights or benefits to the Holders of Senior Exchangeable Preferred Stock or that does not adversely affect the legal rights under this Certificate of Designations of any such Holder. SECTION 11 REISSUANCE Senior Exchangeable Preferred Stock redeemed or otherwise acquired by the Company shall assume the status of authorized but unissued preferred stock and may thereafter be reissued in the same manner as the other authorized but unissued preferred stock, including as Parity Securities, but not as the same class as the Senior Exchangeable Preferred Stock. SECTION 12 OFFICERS' CERTIFICATE Each Officers' Certificate provided for in this Certificate of Designations shall include: (1) a statement that the Officers making such certificate or opinion have read such covenant or condition; (2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; (3) a statement that, in the opinion of each such Officer, he or she has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been satisfied; and (4) a statement as to whether or not, in the opinion of each such Officer, such condition or covenant has been satisfied. SECTION 13 PAYMENT All amounts payable in cash with respect to the Senior Exchangeable Preferred Stock shall be payable in United States dollars at the office or agency of the Company maintained for such purpose within the City and State of New York or, at the option of the Company, payment of dividends (if any) may be made by check mailed to the Holders of the Senior Exchangeable Preferred Stock at their respective addresses set forth in the register of Holders of Senior Exchangeable Preferred Stock maintained by the Transfer Agent; provided that all cash payments with respect to the Global Certificates (as defined below) and shares of Senior Exchangeable Preferred Stock the Holders of which have given wire transfer instructions to the Company shall be required to be made by wire transfer of immediately available funds to the accounts specified by the Holders thereof. Any payment, redemption or exchange with respect to the Senior Exchangeable Preferred Stock due on any day that is not a Business Day need not be made on such day, but may be made on the next succeeding Business Day with the same force and effect as if made on such due date.

(iii) The Transfer Agent shall not be required to register the transfer of or exchange any Senior Exchangeable Preferred Stock selected for redemption in whole or in part, except the unredeemed portion of any certificate evidencing Senior Exchangeable Preferred Stock being redeemed in part. (iv) All Global Certificates and Definitive Certificates issued upon any registration of transfer or exchange of Global Certificates or Definitive Certificates shall be the valid obligations of the Company, entitled to the same benefits under this Certificate of Designations, as the Global Certificates or Definitive Certificates surrendered upon such registration of transfer or exchange. (v) The Company shall not be required (A) to issue, to register the transfer of or to exchange any Senior Exchangeable Preferred Stock during a period beginning at the opening of business 15 days before the day of any selection of Senior Exchangeable Preferred Stock for redemption under Section 6.3 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Senior Exchangeable Preferred Stock so selected for redemption in whole or in part, except the unredeemed portion of any certificate evidencing Senior Exchangeable Preferred Stock being redeemed in part or (c) to register the transfer of or to exchange Senior Exchangeable Preferred Stock between a record date and the next succeeding Interest Payment Date.

Section 15.4 Replacement Senior Exchangeable Preferred Stock If any mutilated Senior Exchangeable Preferred Stock certificate is surrendered to the Transfer Agent or the Company and the Transfer Agent receives evidence to its satisfaction of the destruction, loss or theft of any Senior Exchangeable Preferred Stock certificate, the Company shall issue and the Transfer Agent, upon receipt of an Authentication Order, shall authenticate a replacement certificate evidencing Senior Exchangeable Preferred Stock if the Transfer Agent's requirements are met. If required by the Transfer Agent or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Transfer Agent and the Company to protect the Company, the Transfer Agent, any Agent and any authenticating agent from any loss that any of them may suffer if a Senior Exchangeable Preferred Stock certificate is replaced.

If a certificate evidencing Senior Exchangeable Preferred Stock is replaced pursuant to Section 15.4 hereof, it ceases to be outstanding unless the Transfer Agent receives proof satisfactory to it that the replaced Senior Exchangeable Preferred Stock is held by a bona fide purchaser. If the liquidation preference of any Senior Exchangeable Preferred Stock is considered paid under Section 13 hereof, it ceases to be outstanding and interest on it ceases to accrue. If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Senior Exchangeable Preferred Stock payable on that date, then on and after that date such Senior Exchangeable Preferred Stock shall be deemed to be no longer outstanding and shall cease to accrue interest.

Temporary Senior Exchangeable Preferred Stock shall be substantially in the form of certificated Senior Exchangeable Preferred Stock but may have variations that the Company considers appropriate for temporary Senior Exchangeable Preferred Stock and as shall be reasonably acceptable to the Transfer Agent. Without unreasonable delay, the Company shall prepare and the Transfer Agent shall authenticate Definitive Certificates in exchange for temporary Senior Exchangeable Preferred Stock. Holders of temporary Senior Exchangeable Preferred Stock shall be entitled to all of the benefits of this Certificate of Designations. 54

Section 15.7 Cancellation The Company at any time may deliver Senior Exchangeable Preferred Stock to the Transfer Agent for cancellation. The Transfer Agent and Paying Agent shall forward to the Transfer Agent any Senior Exchangeable Preferred Stock surrendered to them for registration of transfer, exchange or payment. The Transfer Agent and no one else shall cancel all Senior Exchangeable Preferred Stock surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy canceled Senior Exchangeable Preferred Stock (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Senior Exchangeable Preferred Stock shall be delivered to the Company. The Company may not issue new Senior Exchangeable Preferred Stock to replace Senior Exchangeable Preferred Stock that it has paid or that have been delivered to the Transfer Agent for cancellation.

If the Company at any time ------------------------ proposes to register any of its securities under the Securities Act for sale to the public, whether for its own account or for the account of other security holders or both (except with respect to registration statements on Forms S-4, S- 8 or another form not available for registering the Restricted Shares for sale to the public), each such time it will give written notice to all holders of outstanding Restricted Shares of its intention so to do. Upon the written request of any such holder, received by the Company within 20 days after the giving of any such notice by the Company, to register any of its Restricted Shares, the Company will, subject as provided below, cause the Restricted Shares as to which registration shall have been so requested to be included in the securities to be covered by the registration statement proposed to be filed by the Company, all to the extent requisite to permit the sale or other disposition by the holder of such Restricted Shares so registered. In the event that any registration pursuant to this Section 4.01 shall be, in whole or in part, an underwritten public offering of Common Stock, the number of Restricted Shares to be included in such an underwriting may be reduced (pro rata among the requesting holders based upon the number of Restricted Shares owned by such holders) if and to the extent that the managing underwriter shall be of the opinion that such inclusion would adversely affect the marketing of the securities to be sold by the Company therein; provided, however, that such -------- ------- number of Restricted Shares shall not be reduced if any shares are to be included in such underwriting for the account of any person other than the Company or requesting holders of Restricted Shares. Notwithstanding the foregoing provisions, the Company may withdraw any registration statement referred to in this Section 4.01 without thereby incurring any liability to the holders of Restricted Shares. There shall be no limit to the number of registrations of Restricted Shares which may be effected under this Section 4.01. SECTION 4.02. Demand Registration. (a) At any time after the -------------------- expiration of six months after the IPO, TDF may request the Company to register under the Securities Act

20 all or a portion of the shares of Restricted Shares held by it for sale in the manner specified in such notice; provided, that (i) the reasonably anticipated -------- aggregate net proceeds to the sellers from such public offering would exceed $30,000,000, (ii) such request covers at least 5% of the Voting Securities then outstanding and (iii) no such request may be made by TDF more than once every nine months. Notwithstanding anything to the contrary contained herein, no request may be made under this Section 4.02 within 90 days after the effective date of a registration statement filed by the Company covering a firm commitment underwritten public offering in which the holders of Restricted Shares shall have been entitled to join pursuant to Sections 4.01 or 4.03 and in which there shall have been effectively registered all shares of Restricted Shares as to which registration shall have been requested. (b) At any time after the expiration of six months after the IPO, any Stockholder or group of Stockholders may request the Company to register under the Securities Act all or a portion of the shares of Restricted Shares held by such Stockholder or group of Stockholders for sale in the manner specified in such notice; provided, that (i) the reasonably anticipated aggregate net -------- proceeds to the sellers from such public offering would exceed $30,000,000, (ii) such request covers at least 5% of the Voting Securities then outstanding and (iii) no such request may be made by such Stockholders or group of Stockholders more than once every nine months. Notwithstanding anything to the contrary contained herein, no request may be made under this Section 4.02 within 90 days after the effective date of a registration statement filed by the Company covering a firm commitment underwritten public offering in which the holders of Restricted Shares shall have been entitled to join pursuant to Sections 4.01 or 4.03 and in which there shall have been effectively registered all shares of Restricted Shares as to which registration shall have been requested. (c) Following receipt of any notice under this Section 4.02, the Company shall immediately notify all holders of Restricted Shares from whom notice has not been received and shall use its best efforts to register under the Securities Act, for public sale in accordance with the method of disposition specified in such notice from requesting holders, the number of shares of Restricted Shares specified in such notice (and in all notices received by the Company from other holders within 20 days after the giving of such notice by the Company). If such method of disposition shall be an underwritten public offering, the holders of a majority of the shares of Restricted Shares to be sold in such offering may designate the managing

21 underwriter of such offering, subject to the approval of the Company, which approval shall not be unreasonably withheld or delayed. The Company shall be obligated to register Restricted Shares pursuant to Section 4.02(a) on three occasions only and pursuant to Section 4.02(b) on three occasions only, provided, however, that such obligations shall be deemed satisfied only when a - -------- ------- registration statement covering all shares of Restricted Shares specified in notices received as aforesaid, for sale in accordance with the method of disposition specified by the requesting holders, shall have become effective and, if such method of disposition is a firm commitment underwritten public offering, all such shares shall have been sold pursuant thereto unless (i) any such registration statement does not become effective due to the withdrawal thereof by or on the request of the holders of 66% of the shares of Restricted Shares to be registered or (ii) the reason all shares of Restricted Shares specified in notices pursuant to this Section 4.02 are not registered is due to a limitation on the registration of shares by the managing underwriter (which limitation shall be applied pro rata) and no more than 50% of the Restricted Shares so specified are not registered as a result of the limitation imposed by such managing underwriter or the voluntary withdrawal of any such shares from registration by the holder thereof. (d) The Company shall be entitled to include in any registration statement referred to in this Section 4.02, for sale in accordance with the method of disposition specified by the requesting holders, shares of Common Stock to be sold by the Company for its own account, except as and to the extent that, in the opinion of the managing underwriter (if such method of disposition shall be an underwritten public offering), such inclusion would adversely affect the marketing of the Restricted Shares to be sold. Except for registration statements on Forms S-4, S-8 or any successor thereto, the Company will not file with the Commission any other registration statement with respect to its Common Stock, whether for its own account or that of other stockholders, from the date of receipt of a notice from requesting holders pursuant to this Section 4.02 90 days after the commencement of the public offering of the Restricted Shares covered by the registration statement requested pursuant to this Section 4.02. SECTION 4.03. Registration on Form S-3. If at any time (a) a holder ------------------------ or holders of 5% of the Voting Securities request that the Company file a registration statement on Form S-3 or any successor thereto for a public offering of all or any portion of the Restricted Shares held by such requesting holder or holders, the reasonably

22 anticipated aggregate price to the public of which would exceed $30,000,000, and (b) the Company is a registrant entitled to use Form S-3 or any successor thereto to register such shares, then the Company shall use its best efforts to register under the Securities Act on Form S-3 or any successor thereto, for public sale in accordance with the method of disposition specified in such notice, the number of shares of Restricted Shares specified in such notice. Whenever the Company is required by this Section 4.03 to use its best efforts to effect the registration of Restricted Shares, each of the procedures and requirements of Section 4.02 and 4.04 (including but not limited to the requirement that the Company notify all holders of Restricted Shares from whom notice has not been received and provide them with the opportunity to participate in the offering) shall apply to such registration, provided, -------- however, the Company shall not be required to effect more than seven - ------- registrations on Form S-3 which may be requested and obtained under this Section 4.03. SECTION 4.04. Registration Procedures. If and whenever the Company ----------------------- is required by the provisions of Sections 4.01, 4.02 or 4.03 to use its best efforts to effect the registration of any Restricted Shares under the Securities Act, the Company will, as expeditiously as possible: (a) prepare and file with the Commission a registration statement with respect to such securities; (b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for the period specified in paragraph (i) below and comply with the provisions of the Securities Act with respect to the disposition of all Restricted Shares covered by such registration statement in accordance with the sellers' intended method of disposition set forth in such registration statement for such period; (c) furnish to each seller of Restricted Shares and to each underwriter such number of copies of the registration statement and the prospectus included therein (including each preliminary prospectus) as such persons reasonably may request in order to facilitate the public sale or other disposition of the Restricted Shares covered by such registration statement;

23 (d) use its best efforts to register or qualify the Restricted Shares covered by such registration statement under the securities or "blue sky" laws of such jurisdictions as the sellers of Restricted Shares or, in the case of an underwritten public offering, the managing underwriter reasonably shall request; provided, however, that the Company shall not for -------- ------- any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction; (e) use its best efforts to list the Restricted Shares covered by such registration statement with any securities exchange or market on which the Common Stock of the Company, if applicable, is then listed or quoted; (f) immediately notify each seller of Restricted Shares and each underwriter under such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event of which the Company has knowledge as a result of which the prospectus contained in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; (g) at the request of any seller of Restricted Shares, use its best efforts to furnish on the date that Restricted Shares are delivered to the underwriters for sale pursuant to such registration: (i) an opinion dated such date of counsel representing the Company for the purposes of such registration, addressed to the underwriters and to such seller, stating that such registration statement has become effective under the Securities Act and that (A) to the best knowledge of such counsel, no stop order suspending the effectiveness thereof has been issued and no proceedings for that purpose have been instituted or are pending or contemplated under the Securities Act, (B) the registration statement, the related prospectus and each amendment or supplement thereof comply as to form in all material respects with the requirements of the Securities Act (except that such counsel need not express any opinion as to financial statements contained therein) and (C) to such other effects as reasonably may be requested by counsel

24 for the underwriters or by such seller or its counsel and (ii) a letter dated such date from the independent public accountants retained by the Company, addressed to the underwriters and to such seller, stating that they are independent public accountants within the meaning of the Securities Act and that, in the opinion of such accountants, the financial statements of the Company included in the registration statement or the prospectus, or any amendment or supplement thereof, comply as to form in all material respects with the applicable accounting requirements of the Securities Act, and such letter shall additionally cover such other financial matters (including information as to the period ending no more than five business days prior to the date of such letter) with respect to such registration as such underwriters reasonably may request; (h) (i) make available for inspection by each seller of Restricted Shares, any underwriter participating in any distribution pursuant to such registration statement, and any attorney, accountant or other agent retained by such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, (ii) cause the Company's officers, Directors and employees to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement and (iii) provide each seller and its counsel with the opportunity to participate in the preparation of such registration statement; (i) with respect to any registration statement pursuant to which Restricted Shares are to be sold pursuant to Sections 4.01, 4.02 or 4.03, the Company shall use its best efforts to cause such registration statement to become and remain effective for 180 days; and (j) enter into such agreements and take such other actions as the sellers of Restricted Shares and the underwriters reasonably request in order to expedite or facilitate the disposition of such Restricted Shares including, without limitation, preparing for and participating in, such number of "road shows" and all such other customary selling efforts as the underwriters reasonably request in order to expedite or facilitate such disposition.

25 In connection with each registration hereunder, the sellers of Restricted Shares will furnish to the Company in writing such information with respect to themselves and the proposed distribution by them as shall be reasonably necessary in order to assure compliance with Federal and applicable state securities laws. In connection with each registration pursuant to Sections 4.01, 4.02 or 4.03 covering an underwritten public offering, the Company and each seller agree to enter into a written agreement with the managing underwriter selected in the manner herein provided in such form and containing such provisions as are customary in the securities business for such an arrangement between such underwriter and companies of the Company's size and investment stature (it being understood that the Company will not require a selling stockholder to make any representation, warranty or agreement in such agreement other than with respect to such stockholder, the ownership of such stockholder's securities being registered and such stockholder's intended method of disposition). The representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of the underwriters in such written agreement with the underwriters shall also be made to and for the benefit of the selling stockholders. In the event that any condition to the obligations under any such written agreement with the underwriters are not met or waived, and such failure to be met or waived is not attributable to the fault of the selling stockholders requesting a demand registration pursuant to Sections 4.02 and 4.03, such request for registration shall not be deemed exercised for purposes of determining whether such registration has been effected for purposes of Section 4.02 or 4.03. SECTION 4.05. Expenses. Notwithstanding Section 10.10 of the --------- Exchange Agreement, all expenses incurred by the Company in complying with Sections 4.01, 4.02 or 4.03, including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel and independent public accountants for the Company, fees and expenses (including counsel fees) incurred in connection with complying with state securities or "blue sky" laws, fees of the National Association of Securities Dealers, Inc., transfer taxes, fees of transfer agents and registrars, costs of insurance and fees and disbursements of one counsel for the sellers of Restricted Shares, but excluding any Selling Expenses, are called "Registration Expenses". All --------------------- underwriting discounts and selling commissions applicable to the sale of Restricted Shares are called "Selling Expenses". ----------------

26 The Company will pay all Registration Expenses in connection with each registration statement under Sections 4.01, 4.02 or 4.03. All Selling Expenses in connection with each registration statement under Sections 4.01, 4.02 or 4.03 shall be borne by the participating sellers in proportion to the number of shares sold by each, or by such participating sellers other than the Company (except to the extent the Company shall be a seller) as they may agree. SECTION 4.06. Indemnification and Contribution. (a) In the event of --------------------------------- a registration of any of the Restricted Shares under the Securities Act pursuant to Sections 4.01, 4.02 or 4.03, the Company will indemnify and hold harmless each seller of such Restricted Shares thereunder, each underwriter of such Restricted Shares thereunder and each other person, if any, who controls such seller or underwriter within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such seller, underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Restricted Shares were registered under the Securities Act pursuant to Sections 4.01, 4.02 or 4.03, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each such seller, each such underwriter and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the -------- ------- Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished in writing by such seller, such underwriter or such controlling person specifically for use in such registration statement or prospectus. (b) In the event of a registration of any of the Restricted Shares under the Securities Act pursuant to Sections 4.01, 4.02 or 4.03, each seller of such Restricted Shares thereunder, severally and not jointly, will indemnify and hold harmless the Company, each person, if any, who

27 controls the Company within the meaning of the Securities Act, each officer of the Company who signs the registration statement, each Director of the Company, each underwriter and each person who controls any underwriter within the meaning of the Securities Act, against all losses, claims, damages or liabilities, joint or several, to which the Company or such officer, Director, underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement under which such Restricted Shares were registered under the Securities Act pursuant to Sections 4.01, 4.02, or 4.03, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and each such officer, Director, underwriter and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that such seller will be -------- ------- liable hereunder in any such case if and only to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact made in reliance upon and in conformity with information pertaining to such seller, as such, furnished in writing to the Company by such seller specifically for use in such registration statement or prospectus; and provided further, however, that the liability of each seller hereunder shall be - -------- ------- ------- limited to the proportion of any such loss, claim, damage, liability or expense which is equal to the proportion that the public offering price of the shares sold by such seller under such registration statement bears to the total public offering price of all securities sold thereunder, but not in any event to exceed the proceeds received by such seller from the sale of Restricted Shares covered by such registration statement. (c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 4.06 and

28 shall only relieve it from any liability which it may have to such indemnified party under this Section 4.06 if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 4.06 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, if the defendants in any such action -------- ------- include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified party shall have the right to select a separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred. (d) In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any indemnified party exercising rights under this Agreement, or any controlling person of any such holder, makes a claim for indemnification pursuant to this Section 4.06 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 4.06 provides for indemnification in such case, (ii) contribution under the Securities Act may be required on the part of any such selling holder or any such controlling person in circumstances for which indemnification is provided under this Section 4.06, or (iii) the indemnification provided for by this Section 4.06 is insufficient to hold harmless an indemnified party, other than by reason of the exceptions provided therein; then, and in each such case, the Company and such holder will contribute to the aggregate losses,

29 claims, damages or liabilities to which they may be subject (after contribution from others) (x) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party on the other or (y) if the allocation provided by clause (x) above is not permitted by Applicable Law, or provides a lesser sum to the indemnified party than the amount hereinafter calculated, in such proportion as is appropriate to reflect not only the relative fault referred to in clause (x) above but also the relative benefits received by the indemnifying party and the indemnified party from the offering of the securities (taking into account the portion of the proceeds of the offering received by each such party) as well as the statements or omissions which resulted in such losses, claims, damages or liabilities and any other relevant equitable considerations. No person will be required to contribute any amount in excess of the proceeds received by such person in respect of all such Restricted Shares offered and sold by it pursuant to such registration statement and no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation. SECTION 4.07. Changes in Common Stock; Successors. (a) If, and as ------------------------------------ often as, there is any change in the Common Stock or Class A Stock by way of a stock split, stock dividend, combination or reclassification, or through a merger, consolidation, reorganization or recapitalization, or by any other means, appropriate adjustment shall be made in the provisions hereof so that the rights and privileges granted hereby shall continue with respect to the Common Stock or Class A Stock as so changed. (b) If the Company consolidates or merges into or with, another person or sells, assigns, conveys, transfers, leases or otherwise disposes of all or a majority of its assets to any person or group, or any person or group consolidates with, or merges into or with, the Company, each Stockholder shall, as a condition to the relevant transaction involving such person, group or successor in business, be granted by such person, group or successor in business (each a "Successor"), equivalent rights to the rights granted in this Agreement; --------- provided, that in the case of a Successor which becomes a Successor in a - -------------- transaction which constitutes a Business Combination (as such term is defined in the Governance Agreement), such rights shall not include those granted under Article III of this Agreement.

30 SECTION 4.08. Rule 144 Reporting. With a view to making available ------------------- the benefits of certain rules and regulations of the Commission which may at any time permit the sale of Restricted Shares to the public without registration, at all times 90 days after any registration statement covering a public offering of securities of the Company under the Securities Act shall have become effective, the Company agrees to: (a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act; (b) use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (c) furnish to each holder of Restricted Shares forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of such Rule 144 and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as such holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such holder to sell any Restricted Shares without registration. SECTION 4.09. Suspension of Registration Obligations. --------------------------------------- Notwithstanding the provisions of Section 4.04(a), (i) the Company's obligation to file a registration statement, or cause such registration statement to become and remain effective (a) may be suspended on one occasion for a period not to exceed 180 days if there exists at the time material nonpublic information relating to the Company which, in the reasonable opinion of the Company, should not be disclosed and (b) shall not apply for the period which begins seven days prior to and ends 90 days after the commencement of a public offering of the Common Stock, so long as the Company has fulfilled its notice obligations under Sections 4.01, 4.02 or 4.03 with respect to such offering and (ii) if a public offering of the Common Stock has been previously commenced, neither the Company nor any controlling person of the Company shall commence another public offering of the Common Stock until 90 days after the commencement of such prior offering. SECTION 4.10. Transferability of Registration Rights; Termination. ---------------------------------------------------- (a) Registration rights conferred

31 herein on the holders of Restricted Shares shall only inure to the benefit of a Prospective Transferee who becomes a party to this Agreement pursuant to Section 2.05. (b) The obligations of the Company to register shares of Restricted Shares under Sections 4.01, 4.02 or 4.03 shall terminate as to each Stockholder, on the later of (i) the sixth anniversary of the date of this Agreement and (ii) such Stockholder's percentage (together with the percentage of Voting Securities held by any member(s) of such Stockholder's Group) of Voting Securities falling below 5%. SECTION 4.11. Other Registration Rights. The Company has not granted -------------------------- and shall not grant to any third party any registration rights more favorable than or inconsistent with any of those contained herein, so long as any of the registration rights under this Agreement remains in effect.

SECTION 4.02. Negative Covenants. (a) Notwithstanding any other ------------------- provision of the Transaction Documents, neither the Company, any of its Subsidiaries, TDF nor any member of the TDF Group shall take or approve any action which would result in the BBC having the right to terminate a BBC Contract in accordance with the terms of such BBC Contract. (b) TDF agrees that neither TDF nor any member of the TDF Group shall enter into any transaction falling within a Permitted Business Line which TDF Vetoed in accordance with Section 4.01(b)(iii) and Section 4.01(b)(iv) within six months after the relevant Veto. SECTION 4.03. Successors to the Company. The Company shall procure -------------------------- that TDF shall be granted by any Newco equivalent rights to the rights contained in this Agreement as a condition to any transaction involving the creation of any such Newco. ARTICLE V CTSH Option ----------- SECTION 5.01. CTSH Option. (a) Notwithstanding any other provision ------------ of this Agreement, TDF shall have the right to the CTSH Option (as defined) if, and only if, TDF is Qualified and (i)(A) the Board has approved a Business Combination by a Special Majority Vote, (B) TDF thereafter gives a Veto in respect of such Business Combination in accordance with Section 4.01(b) and 4.01(c) and (C) subsequent to the exercise of the Veto by TDF, a majority of the entire Board (excluding the two TDF Designees) resolves that such Veto by TDF shall be

30 overridden in accordance with this Section 5.01; (ii) the commencement or occurrence of an Unsolicited Offer by any person (other than any member of the TDF Group); or (iii) a Special Business Combination shall have been commenced by any person (other than any member of the TDF Group), TDF shall have the option, exercisable, subject to subparagraph (d) below, irrevocably by notice in writing given to the Company within five days following agreement between the parties as to, or (as the case may be), receipt of notice of the determination of the Fair Market Value per share of the CTSH Shares and the CTSH Warrants (assuming the payment of the exercise price of such Warrants) (the "CTSH Per Share Value") as -------------------- set forth below, to (x) acquire for cash by itself or together with any other person, all, but not less than all, the Company CTSH Shares at such CTSH Per Share Value, (y) sell for cash to the Company the TDF CTSH Shares and the TDF CTSH Warrants at such CTSH Per Share Value or (z) maintain the TDF CTSH Shares and the TDF CTSH Warrants without regard to the event giving rise to the CTSH Option (the "CTSH Option"). ----------- (b) The valuation procedures shall be as follows. Each of the Company and TDF shall, commencing upon the date of the occurrence of any of the events set forth in Section 5.01(a)(i)(C), Section 5.01(a)(ii) or Section 5.01(a)(iii), negotiate in good faith to determine a CTSH Per Share Value of the CTSH Shares within thirty days following the occurrence of any such event. If the parties do not agree on a CTSH Per Share Value within such thirty-day period, they shall, within three days, appoint an independent investment banker of international stature with its principal office in New York City (the "Appraiser") and shall --------- provide such Appraiser with their respective written determinations of the CTSH Per Share Value. Such Appraiser shall then choose (taking into account all relevant factors, but no discount shall be applied as a result of the termination or potential termination of the BBC Contracts), as between the written determinations of the CTSH Per Share Value provided by each party to the Appraiser, the CTSH Per Share Value which most closely approximates, in the expert opinion of the Appraiser, the Fair Market Value per share of the CTSH Shares and the CTSH Warrants. If the parties are unable to agree on the selection of such Appraiser within such three-day period, they shall on such third day so notify the Chairman of the New York Stock Exchange, Inc., who shall, within five days of such notification, (or if unwilling or unable to serve in such capacity, the senior partner of one the following accounting firms, in order of priority for selection, KPMG Peat Marwick LLP, Price Waterhouse LLP, Ernst & Young LLP and Arthur Anderson LLP) appoint an investment banker meeting the qualifications set

31 forth above to serve as the Appraiser. In any case, the Appraiser shall make its decision with respect to the CTSH Per Share Value within ten days of the date of its engagement and must choose a Value presented by either of the parties pursuant to their respective written determinations (i.e., such Appraiser may ---- not select a different value). The fees and expenses of the Appraiser shall be paid by the Company. (c) If a Business Combination, Unsolicited Offer or Special Business Combination is abandoned or terminated, the CTSH Option and any exercise thereof by TDF pursuant to Section 5.01(a)(x) or (y) shall become null and void and ownership in CTSH shall continue as if such CTSH Option had not come into effect, unless the Company exercises its right to cause TDF to purchase the Company CTSH Shares pursuant to subparagraph (d) below. (d) Any closing of a sale and purchase of CTSH Shares pursuant to the CTSH Option shall take place on the date of consummation of the Business Combination and, subject as provided in the next following sentence, the Unsolicited Offer or Special Business Combination which gave rise thereto, subject to the satisfaction or waiver of the Conditions Precedent; provided that -------- any such Business Combination may not be consummated by the Company other than substantially simultaneously with (but not before) the consummation of the sale and purchase of the CTSH Shares pursuant to such CTSH Option; provided further ---------------- that each of the Company and TDF shall continue to use its reasonable best efforts to obtain the satisfaction or waiver of such Conditions Precedent so long as such Business Combination, Unsolicited Offer a Special Business Combination is outstanding. In the case of an Unsolicited Offer or a Special Business Combination, if TDF has elected to exercise the CTSH Option pursuant to Section 5.01(a)(x) and the Conditions Precedent to such CTSH Option are not waived or satisfied on or before the third Business Day prior to the date of consummation of the Unsolicited Offer or the Special Business Combination which gave rise to such CTSH Option, TDF shall have the option by written notice (a "Withdrawal Notice") to the Company to be given no later than the date of ----------------- consummation of such Unsolicited Offer or Special Business Combination, as applicable, to declare the exercise of the CTSH Option pursuant to Section 5.01(a)(x) to be null and void and to exercise the CTSH Option pursuant to either Section 5.01(a)(y) or Section 5.01(a)(z) in lieu thereof. If TDF fails to give a Withdrawal Notice prior to the date of consummation of the Unsolicited Offer or the Special Business Combination, TDF shall be deemed to have affirmed

32 the exercise of the CTSH Option pursuant to Section 5.01(a)(x). If such Business Combination is not consummated (or an Unsolicited Offer or Special Business Combination is abandoned or terminated) by reason primarily of the exercise by TDF of the CTSH Option pursuant to Section 5.01(a)(x), then the Company may nevertheless require TDF to proceed with the purchase (the "Required Purchase") of the Company CTSH Shares at the CTSH Per ----------------- Share Value, subject to the satisfaction or waiver of the Conditions Precedent and the non-occurrence prior to the closing of the Required Purchase of (i) any event or development of a state of circumstances or facts which has had or is reasonably likely to have, individually or in the aggregate, a Material Adverse Effect on CTSH and its Subsidiaries taken as a whole or (ii)(A) a suspension of trading in the Company's Common Stock by the Commission or Nasdaq or the establishment of limited or minimum prices in trading of securities generally on the New York Stock Exchange, Inc., or Nasdaq or (B) banking moratoriums having been declared either by Federal or New York State authorities. Such Required Purchase by TDF of the Company CTSH Shares shall, subject to the satisfaction or waiver of the Conditions Precedent and the nonoccurrence of any such event as aforesaid, close thirty days after announcement of the abandonment or termination of such Business Combination, Unsolicited Offer, or Special Business Combination, as applicable (or, if later, the second Business Day following the date of the satisfaction or waiver of the Conditions Precedent). If TDF shall exercise the CTSH Option pursuant to Section 5.01(a)(x), TDF may pay all or any part of the purchase price therefor by surrendering to the Company on the closing of such exercise shares of Class A Stock (which shall be valued at the offer price per share of Common Stock pursuant to the Business Combination, Unsolicited Offer, or Special Business Combination, as applicable, giving rise to the CTSH Option). (e) If the price offered in any proposed Business Combination, Unsolicited Offer or Special Business Combination is increased or decreased by the offeror by more than 10% after the commencement or determination of the CTSH Per Share Value pursuant to subparagraph (b), the Company shall promptly notify the Appraiser of such increase or decrease and the Appraiser shall take into account such increase or decrease (and any other relevant factor in connection therewith), except that if the Appraiser has previously completed the appraisal procedure set forth in such subparagraph (b) and selected the CTSH Per Share Value, (i) such appraisal procedure shall recommence and the choice of the CTSH Per Share Value by the Appraiser shall be made

33 within five days of the notice to the Appraiser by the Company of such increase or decrease and (ii) any exercise by TDF of the CTSH Option by written notice to the Company pursuant to Section 5.01(b) shall be null and void, and TDF may thereafter exercise the CTSH Option by subsequent written notice to the Company in accordance with such Section 5.01(b). (f) Immediately prior to the consummation of any Business Combination, Unsolicited Offer or Special Business Combination, TDF shall have the right to require the Company to purchase one-half (1/2) of the shares of Class A Stock held by the TDF Group, as applicable, for cash in an amount equal to the product of (x) the offer price per share of Common Stock pursuant to the Business Combination, Unsolicited Offer or Special Business Combination, as applicable, and (y) one-half (1/2) of the number of such shares of Class A Stock held by the TDF Group.

(b) Upon receipt by the Company and the Rights Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a valid Right Certificate, and, in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to them, and, at the Company's request, reimbursement to the Company and the Rights Agent of all reasonable expenses incidental thereto, and upon surrender to the Rights Agent and cancelation of the Right Certificate if mutilated, the Company shall make a new Right Certificate of like tenor and deliver such new Right Certificate to the Rights Agent for delivery to the registered owner in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

16 (c) Notwithstanding any other provision hereof, the Company and the Rights Agent may amend this Rights Agreement to provide for uncertificated Rights in addition to or in place of Rights evidenced by Right Certificates. SECTION 7. Exercise of Rights; Expiration Date of Rights. (a) ---------------------------------------------- Subject to Section 7(e) and except as otherwise provided herein (including Section 11), each Right shall entitle the registered holder thereof, upon exercise thereof as provided herein, to purchase for the Purchase Price, at any time after the Distribution Date and at or prior to the earliest of (i) the Close of Business on the 10th anniversary of the date of this Rights Agreement (the Close of Business on such date being the "Expiration Date") and (ii) the Redemption Date, one one-thousandth (1/1,000th) of a Preferred Share, subject to adjustment from time to time as provided in Sections 11 and 12. (b) The registered holder of any Right Certificate may exercise the Rights evidenced thereby (except as otherwise provided herein) in whole or in part at any time after the Distribution Date, upon surrender of the Right Certificate, with the form of election to purchase on the reverse side thereof duly executed, to the Rights Agent at the principal office of the Rights Agent in New Jersey, together with payment of the Purchase Price for each one one- thousandth (1/1,000th) of a Preferred Share as to which the Rights are exercised, at or prior to the earlier of (i) the Expiration Date or (ii) the Redemption Date. (c) Upon receipt of a Right Certificate representing exercisable Rights, with the form of election to purchase duly executed, accompanied by payment of the Purchase Price for the Preferred Shares to be purchased together with an amount equal to any applicable transfer tax, in lawful money of the United States of America, in cash or by certified check or money order payable to the order of the Company, the Rights Agent shall thereupon (i) either (A) promptly requisition from any transfer agent of the Preferred Shares (or make available, if the Rights Agent is the transfer agent) certificates for the number of Preferred Shares to be purchased and the Company hereby irrevocably authorizes its transfer agent to comply with all such requests or (B) if the Company shall have elected to deposit the Preferred Shares with a depositary agent under a depositary arrangement, promptly requisition from the depositary agent depositary receipts representing the number of one one-thousandths (1/1,000s) of a Preferred Share to be purchased (in which case certificates for the Preferred Shares to be represented by such receipts shall be deposited by the transfer agent with the depositary agent) and the

17 Company shall direct the depositary agent to comply with all such requests, (ii) when appropriate, promptly requisition from the Company the amount of cash to be paid in lieu of issuance of fractional shares in accordance with Section 15, (iii) promptly after receipt of such certificates or depositary receipts, cause the same to be delivered to or upon the order of the registered holder of such Right Certificate, registered in such name or names as may be designated by such holder and (iv) when appropriate, after receipt promptly deliver such cash to or upon the order of the registered holder of such Right Certificate. (d) In case the registered holder of any Right Certificate shall exercise fewer than all the Rights evidenced thereby, a new Right Certificate evidencing Rights equivalent to the Rights remaining unexercised shall be issued by the Rights Agent and delivered to the registered holder of such Right Certificate or to his duly authorized assigns, subject to the provisions of Section 15. (e) Notwithstanding anything in this Rights Agreement to the contrary, any Rights that are at any time beneficially owned by (i) an Acquiring Person or an Affiliate or Associate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee after the Acquiring Person becomes such (other than pursuant to the penultimate sentence of the definition of "Acquiring Person"), or (iii) a transferee of an Acquiring Person (or of any such Associate or Affiliate) who becomes a transferee prior to or concurrently with the Acquiring Person becoming such and receives such Rights pursuant to either (A) a transfer (whether or not for consideration) from the Acquiring Person to holders of equity interests in such Acquiring Person or to any Person with whom the Acquiring Person has any continuing agreement, arrangement or understanding regarding the transferred Rights or (B) a transfer which the Board of Directors of the Company has determined is part of a plan, arrangement or understanding which has as a primary purpose or effect the avoidance of this Section 7(e), shall become null and void without any further action and no holder of such Rights shall have any rights whatsoever with respect to such Rights, whether under any provision of this Rights Agreement or otherwise. The Company shall use all reasonable efforts to ensure that the provisions of this Section 7(e) are complied with, but shall have no liability to any holder of any Right Certificate or any other Person as a result of its failure to make any determinations with respect to an Acquiring Person or its Affiliate or Associate, or any transferee thereof, hereunder.

18 (f) Notwithstanding anything in this Rights Agreement to the contrary, neither the Rights Agent nor the Company shall be obligated to undertake any action with respect to a registered holder of any Right Certificates upon the occurrence of any purported exercise as set forth in this Section 7 unless such registered holder shall have (i) completed and signed the certificate contained in the form of election to purchase set forth on the reverse side of the Right Certificate surrendered for such exercise and (ii) provided such additional evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the Company shall reasonably request. (g) The Company may temporarily suspend, for a period of time not to exceed 90 calendar days after the Distribution Date, the exercisability of the Rights in order to prepare and file a registration statement under the Securities Act, on an appropriate form, with respect to the Preferred Shares purchasable upon exercise of the Rights and permit such registration statement to become effective; provided, however, that no such suspension shall remain -------- ------- effective after, and the Rights shall without any further action by the Company or any other Person become exercisable immediately upon, the effectiveness of such registration statement. Upon any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended and shall issue a further public announcement at such time as the suspension is no longer in effect. Notwithstanding any provision herein to the contrary, the Rights shall not be exercisable in any jurisdiction if the requisite qualification under the blue sky or securities laws of such jurisdiction shall not have been obtained or the exercise of the Rights shall not be permitted under applicable law. SECTION 8. Cancelation and Destruction of Right Certificates. All -------------------------------------------------- Right Certificates surrendered or presented for the purpose of exercise, transfer, split-up, combination or exchange shall, and any Right Certificate representing Rights that have become null and void and nontransferable pursuant to Section 7(e) surrendered or presented for any purpose shall, if surrendered or presented to the Company or to any of its agents, be delivered to the Rights Agent for cancelation or in canceled form, or, if surrendered or presented to the Rights Agent, shall be canceled by it, and no Right Certificates shall be issued in lieu thereof except as expressly permitted by this Rights Agreement. The Company shall deliver to the Rights Agent for cancelation and retirement, and the Rights Agent shall so cancel and retire, any Right Certificate purchased or

19 acquired by the Company. The Rights Agent shall deliver all canceled Right Certificates to the Company, or shall, at the written request of the Company, destroy such canceled Right Certificates, and in such case shall deliver a certificate of destruction thereof to the Company. SECTION 9. Reservation and Availability of Preferred Shares. (a) ------------------------------------------------- The Company covenants and agrees that it shall cause to be reserved and kept available out of its authorized and unissued Preferred Shares or any authorized and issued Preferred Shares held in its treasury, free from preemptive rights or any right of first refusal, a number of Preferred Shares sufficient to permit the exercise in full of all outstanding Rights. (b) In the event that there shall not be sufficient Preferred Shares issued but not outstanding or authorized but unissued to permit the exercise or exchange of Rights in accordance with Section 11, the Company covenants and agrees that it shall take all such action as may be necessary to authorize additional Preferred Shares for issuance upon the exercise or exchange of Rights pursuant to Section 11; provided, however, that if the Company is unable to -------- ------- cause the authorization of additional Preferred Shares, then the Company shall, or in lieu of seeking any such authorization, the Company may, to the extent necessary and permitted by applicable law and any agreements or instruments in effect prior to the Distribution Date to which it is a party, (i) upon surrender of a Right, pay cash equal to the Purchase Price in lieu of issuing Preferred Shares and requiring payment therefor, (ii) upon due exercise of a Right and payment of the Purchase Price for each Preferred Share as to which such Right is exercised, issue equity securities having a value equal to the value of the Preferred Shares that otherwise would have been issuable pursuant to Section 11, which value shall be determined by a nationally recognized investment banking firm selected by the Board of Directors of the Company, or (iii) upon due exercise of a Right and payment of the Purchase Price for each Preferred Share as to which such Right is exercised, distribute a combination of Preferred Shares, cash and/or other equity and/or debt securities having an aggregate value equal to the value of the Preferred Shares that otherwise would have been issuable pursuant to Section 11, which value shall be determined by a nationally recognized investment banking firm selected by the Board of Directors of the Company. To the extent that any legal or contractual restrictions (pursuant to agreements or instruments in effect prior to the Distribution Date to which it is party) prevent the Company from paying the full amount payable in accordance with the

20 foregoing sentence, the Company shall pay to holders of the Rights as to which such payments are being made all amounts that are not then restricted on a pro rata basis as such payments become permissible under such legal or contractual restrictions until such payments have been paid in full. (c) The Company covenants and agrees that it shall take all such action as may be necessary to ensure that all Preferred Shares delivered upon exercise or exchange of Rights shall, at the time of delivery of the certificates for such Preferred Shares (subject to payment of the Purchase Price), be duly and validly authorized and issued and fully paid and nonassessable shares. (d) So long as the Preferred Shares issuable upon the exercise or exchange of Rights are to be listed on any national securities exchange, the Company covenants and agrees to use its best efforts to cause, from and after such time as the Rights become exercisable or exchangeable, all Preferred Shares reserved for such issuance to be listed on such securities exchange upon official notice of issuance upon such exercise or exchange. (e) The Company further covenants and agrees that it shall pay when due and payable any and all Federal and state transfer taxes and charges which may be payable in respect of the issuance or delivery of Right Certificates or of any Preferred Shares or Common Stock or other securities upon the exercise or exchange of the Rights. The Company shall not, however, be required to pay any transfer tax which may be payable in respect of any transfer or delivery of Right Certificates to a Person other than, or in respect of the issuance or delivery of certificates for the Preferred Shares or Common Stock or other securities, as the case may be, in a name other than that of, the registered holder of the Right Certificate evidencing Rights surrendered for exercise or exchange or to issue or deliver any certificates for Preferred Shares or Common Stock or other securities, as the case may be, upon the exercise or exchange of any Rights until any such tax shall have been paid (any such tax being payable by the holder of such Right Certificate at the time of surrender) or until it has been established to the Company's satisfaction that no such tax is due. SECTION 10. Preferred Shares Record Date. Each Person in whose name ----------------------------- any certificate for Preferred Shares or Common Stock or other securities is issued upon the exercise or exchange of Rights shall for all purposes be deemed to have become the holder of record of the Preferred Shares or Common Stock or other securities, as the case may be,

21 represented thereby on, and such certificate shall be dated, the date on which the Right Certificate evidencing such Rights was duly surrendered and payment of any Purchase Price (and any applicable transfer taxes) was made; provided, -------- however, that, if the date of such surrender and payment is a date upon which - ------- the transfer books of the Company for the Preferred Shares or Common Stock or other securities, as the case may be, are closed, such Person shall be deemed to have become the record holder of such Preferred Shares or Common Stock or other securities, as the case may be, on, and such certificate shall be dated, the next succeeding Business Day on which the transfer books of the Company for the Preferred Shares or Common Stock or other securities, as the case may be, are open. SECTION 11. Adjustments in Rights After There Is an Acquiring Person; --------------------------------------------------------- Exchange of Rights for Shares; Business Combinations. (a) Upon a Person - ----------------------------------------------------- becoming an Acquiring Person, proper provision shall be made so that each holder of a Right, except as provided in Section 7(e), shall thereafter have a right to receive, upon exercise thereof for the Purchase Price in accordance with the terms of this Rights Agreement, such number of one one-thousandths (1/1,000s) of a Preferred Share as shall equal the result obtained by multiplying the Purchase Price by a fraction, the numerator of which is the number of one one-thousandths (1/1,000s) of a Preferred Share for which such Right is then exercisable and the denominator of which is 50% of the Market Value of the Common Stock on the date on which such Person became an Acquiring Person. As soon as practicable after a Person becomes an Acquiring Person (provided the Company shall not have elected to make the exchange permitted by Section 11(b)(i) for all outstanding Rights), the Company covenants and agrees to use its best efforts to: (i) prepare and file a registration statement under the Securities Act, on an appropriate form, with respect to the Preferred Shares purchasable upon exercise of the Rights; (ii) cause such registration statement to become effective as soon as practicable after such filing; (iii) cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the Expiration Date; and (iv) qualify or register the Preferred Shares purchasable upon exercise of the Rights under the blue

22 sky or securities laws of such jurisdictions as may be necessary or appropriate. (b)(i) The Board of Directors of the Company may, at its option, at any time after a Person becomes an Acquiring Person, mandatorily exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that shall have become null and void and nontransferable pursuant to the provisions of Section 7(e)) for consideration per Right consisting of either (A) one-half of the securities that would be issuable at such time upon the exercise of one Right in accordance with Section 11(a) or, if applicable, Section 9(b)(ii) or 9(b)(iii) or (B) if applicable, the cash consideration specified in Section 9(b)(i) (the consideration issuable per Right pursuant to this Section 11(b)(i) being the "Exchange Consideration"). The Board of Directors of the Company may, at its option, issue, in substitution for Preferred Shares, Common Stock in an amount per Preferred Share equal to the Formula Number (as defined in the Certificate of Designation) if there are sufficient shares of Common Stock issued but not outstanding or authorized but unissued. If the Board of Directors of the Company elects to exchange all the Rights for the Exchange Consideration pursuant to this Section 11(b)(i) prior to the physical distribution of the Right Certificates, the Corporation may distribute the Exchange Consideration in lieu of distributing Right Certificates, in which case for purposes of this Rights Agreement holders of Rights shall be deemed to have simultaneously received and surrendered for exchange Right Certificates on the date of such distribution. (ii) Any action of the Board of Directors of the Company ordering the exchange of any Rights pursuant to Section 11(b)(i) shall be irrevocable and, immediately upon the taking of such action and without any further action and without any notice, the right to exercise any such Right pursuant to Section 11(a) shall terminate and the only right thereafter of a holder of such Right shall be to receive the Exchange Consideration in exchange for each such Right held by such holder or, if the Exchange Consideration shall not have been paid or issued, to exercise any such Right pursuant to Section 11(c)(i). The Company shall promptly give public notice of any such exchange; provided, however, that -------- ------- the failure to give, or any defect in, such notice shall not affect the validity of such exchange. The Company promptly shall mail a notice of any such exchange to all holders of such Rights at their last addresses as they appear upon the registry books of the Rights Agent. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the

23 notice. Each such notice of exchange shall state the method by which the exchange of the Rights for the Exchange Consideration will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which shall have become null and void and nontransferable pursuant to the provisions of Section 7(e)) held by each holder of Rights. (c) (i) In the event that, following a Distribution Date, directly or indirectly, any transactions specified in the following clause (A), (B) or (C) of this Section 11(c)(i) (each such transaction being a "Business Combination") shall be consummated: (A) the Company shall consolidate with, or merge with and into, any Acquiring Person or any Affiliate or Associate of an Acquiring Person; (B) any Acquiring Person or any Affiliate or Associate of an Acquiring Person shall merge with and into the Company and, in connection with such merger, all or part of the Common Shares shall be changed into or exchanged for capital stock or other securities of the Company or of any Acquiring Person or Affiliate or Associate of an Acquiring Person or cash or any other property; or (C) the Company shall sell, lease, exchange or otherwise transfer or dispose of (or one or more of its Subsidiaries shall sell, lease, exchange or otherwise transfer or dispose of), in one or more transactions, the Major Part of the assets of the Company and its Subsidiaries (taken as a whole) to any Acquiring Person or any Affiliate or Associate of an Acquiring Person, then, in each such case, proper provision shall be made so that each holder of a Right, except as provided in Section 7(e), shall thereafter have the right to receive, upon the exercise thereof for the Purchase Price in accordance with the terms of this Rights Agreement, the securities specified below (or, at such holder's option, the securities specified in Section 11(a)): (1) if the Principal Party in such Business Combination has Registered Common Shares outstanding, each Right shall thereafter represent the right to receive, upon the exercise thereof for the Purchase Price in accordance with the terms of this Rights Agreement, such number of Registered Common Shares of

24 such Principal Party, free and clear of all liens, encumbrances or other adverse claims, as shall have an aggregate Market Value as of the time of exercise thereof equal to the result obtained by multiplying the Purchase Price by two; (2) if the Principal Party involved in such Business Combination does not have Registered Common Shares outstanding, each Right shall thereafter represent the right to receive, upon the exercise thereof for the Purchase Price in accordance with the terms of this Rights Agreement, at the election of the holder of such Right at the time of the exercise thereof, any of: (x) such number of Common Shares of the Surviving Person in such Business Combination as shall have an aggregate Book Value immediately after giving effect to such Business Combination equal to the result obtained by multiplying the Purchase Price by two; (y) such number of Common Shares of the Principal Party in such Business Combination (if the Principal Party is not also the Surviving Person in such Business Combination) as shall have an aggregate Book Value immediately after giving effect to such Business Combination equal to the result obtained by multiplying the Purchase Price by two; or (z) if the Principal Party in such Business Combination is an Affiliate of one or more Persons that has Registered Common Shares outstanding, such number of Registered Common Shares of whichever of such Affiliates of the Principal Party has Registered Common Shares with the greatest aggregate Market Value on the date of consummation of such Business Combination as shall have an aggregate Market Value on the date of such Business Combination equal to the result obtained by multiplying the Purchase Price by two. (ii) The Company shall not consummate any Business Combination unless each issuer of Common Shares for which Rights may be exercised, as set forth in this Section 11(c), shall have sufficient authorized Common Shares that have not been issued or reserved for issuance (and which shall, when issued upon exercise thereof in accordance with this Rights Agreement, be validly issued, fully paid and nonassessable and free of preemptive rights,

25 rights of first refusal or any other restrictions or limitations on the transfer or ownership thereof) to permit the exercise in full of the Rights in accordance with this Section 11(c) and unless prior thereto: (A) a registration statement under the Securities Act on an appropriate form, with respect to the Rights and the Common Shares of such issuer purchasable upon exercise of the Rights, shall be effective under the Securities Act; and (B) the Company and each such issuer shall have: (i) executed and delivered to the Rights Agent a supplemental agreement providing for the assumption by such issuer of the obligations set forth in this Section 11(c) (including the obligation of such issuer to issue Common Shares upon the exercise of Rights in accordance with the terms set forth in Sections 11(c)(i) and 11(c)(iii)) and further providing that such issuer, at its own expense, shall use its best efforts to: (x) cause a registration statement under the Securities Act on an appropriate form, with respect to the Rights and the Common Shares of such issuer purchasable upon exercise of the Rights, to remain effective (with a prospectus at all times meeting the requirements of the Securities Act) until the Expiration Date; (y) qualify or register the Rights and the Common Shares of such issuer purchasable upon exercise of the Rights under the blue sky or securities laws of such jurisdictions as may be necessary or appropriate; and (z) list the Rights and the Common Shares of such issuer purchasable upon exercise of the Rights on each national securities exchange on which the Common Shares were listed prior to the consummation of the Business Combination or, if the Common Shares were not listed on a national securities exchange prior to the consummation of the Business Combination, on a national securities exchange;

26 (2) furnished to the Rights Agent a written opinion of independent counsel stating that such supplemental agreement is a valid, binding and enforceable agreement of such issuer; and (3) filed with the Rights Agent a certificate of a nationally recognized firm of independent accountants setting forth the number of Common Shares of such issuer that may be purchased upon the exercise of each Right after the consummation of such Business Combination. (iii) After consummation of any Business Combination and subject to the provisions of Section 11(c)(ii), (A) each issuer of Common Shares for which Rights may be exercised as set forth in this Section 11(c) shall be liable for, and shall assume, by virtue of such Business Combination, all the obligations and duties of the Company pursuant to this Rights Agreement, (B) the term "Company" shall thereafter be deemed to refer to such issuer, (C) each such issuer shall take such steps in connection with such consummation as may be necessary to assure that the provisions hereof (including the provisions of Sections 11(a), 11(b) and 11(c)) shall thereafter be applicable, as nearly as reasonably may be, in relation to its Common Shares thereafter deliverable upon the exercise of the Rights, and (D) the number of Common Shares of each such issuer thereafter receivable upon exercise of any Right shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions of Sections 11 and 12 and the provisions of Section 7, 9 and 10 with respect to the Preferred Shares shall apply, as nearly as reasonably may be, on like terms to any such Common Shares. SECTION 12. Certain Adjustments. (a) To preserve the actual or -------------------- potential economic value of the Rights, if at any time after the date of this Rights Agreement there shall be any change in the Common Shares or the Preferred Shares, whether by reason of stock dividends, stock splits, recapitalizations, mergers, consolidations, combinations or exchanges of securities, split-ups, split-offs, spin-offs, liquidations, other similar changes in capitalization, any distribution or issuance of cash, assets, evidences of indebtedness or subscription rights, options or warrants to holders of Common Shares or Preferred Shares, as the case may be (other than distribution of the Rights or regular quarterly cash dividends), or otherwise, then, in each such event the Board of Directors of the Company shall make such appropriate adjustments in the number of Preferred Shares (or the number and kind of other

27 securities) issuable upon exercise of each Right, the Purchase Price and Redemption Price in effect at such time and the number of Rights outstanding at such time (including the number of Rights or fractional Rights associated with each Common Share) such that following such adjustment such event shall not have had the effect of reducing or limiting the benefits the holders of the Rights would have had absent such event. (b) If, as a result of an adjustment made pursuant to Section 12(a), the holder of any Right thereafter exercised shall become entitled to receive any securities other than Preferred Shares, thereafter the number of such securities so receivable upon exercise of any Right shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions of Sections 11 and 12 and the provisions of Sections 7, 9 and 10 with respect to the Preferred Shares shall apply, as nearly as reasonably may be, on like terms to any such other securities. (c) All Rights originally issued by the Company subsequent to any adjustment made to the amount of Preferred Shares or other securities relating to a Right shall evidence the right to purchase, for the Purchase Price, the adjusted number and kind of securities purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein. (d) Irrespective of any adjustment or change in the Purchase Price or the number of Preferred Shares or number or kind of other securities issuable upon the exercise of the Rights, the Right Certificates theretofore and thereafter issued may continue to express the terms that were expressed in the initial Right Certificates issued hereunder. (e) In any case in which action taken pursuant to Section 12(a) requires that an adjustment be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event the issuing to the holder of any Right exercised after such record date the Preferred Shares and/or other securities, if any, issuable upon such exercise over and above the Preferred Shares and/or other securities, if any, issuable before giving effect to such adjustment; provided, however, that the -------- ------- Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional securities upon the occurrence of the event requiring such adjustment.

28 SECTION 13. Certificate of Adjustment. Whenever an adjustment is -------------------------- made as provided in Section 11 or 12, the Company shall (a) promptly prepare a certificate setting forth such adjustment and a brief statement of the facts accounting for such adjustment, (b) promptly file with the Rights Agent and with each transfer agent for the Preferred Shares a copy of such certificate and (c) mail a brief summary thereof to each holder of a Right Certificate (or, prior to the Distribution Date, of the Common Shares) in accordance with Section 25. The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment therein contained. SECTION 14. Additional Covenants. (a) Notwithstanding any other --------------------- provision of this Rights Agreement, no adjustment to the number of Preferred Shares (or fractions of a share) or other securities for which a Right is exercisable or the number of Rights outstanding or associated with each Common Share or any similar or other adjustment shall be made or be effective if such adjustment would have the effect of reducing or limiting the benefits the holders of the Rights would have had absent such adjustment, including the benefits under Sections 11 and 12, unless the terms of this Rights Agreement are amended so as to preserve such benefits. (b) The Company covenants and agrees that, after the Distribution Date, except as permitted by Section 26, it shall not take (or permit any Subsidiary of the Company to take) any action if at the time such action is taken it is intended or reasonably foreseeable that such action will reduce or otherwise limit the benefits the holders of the Rights would have had absent such action, including the benefits under Sections 11 and 12. Any action taken by the Company during any period after any Person becomes an Acquiring Person but prior to the Distribution Date shall be null and void unless such action could be taken under this Section 14(b) from and after the Distribution Date. The Company shall not consummate any Business Combination if any issuer of Common Shares for which Rights may be exercised after such Business Combination in accordance with Section 11(c) shall have taken any action that reduces or otherwise limits the benefits the holders of the Rights would have had absent such action, including the benefits under Sections 11 and 12. SECTION 15. Fractional Rights and Fractional Shares. (a) The ---------------------------------------- Company may, but shall not be required to, issue fractions of Rights or distribute Right Certificates which evidence fractional Rights. In lieu of such fractional Rights, the Company may pay to the registered

29 holders of the Right Certificates with regard to which such fractional Rights would otherwise be issuable an amount in cash equal to the same fraction of the current market value of a whole Right. For purposes of this Section 15(a), the current market value of a whole Right shall be the closing price of the Rights (as determined pursuant to the second and third sentences of the definition of Market Value contained in Section 1) for the Trading Day immediately prior to the date on which such fractional Rights would have been otherwise issuable. (b) The Company may, but shall not be required to, issue fractions of Preferred Shares upon exercise of the Rights or distribute certificates that evidence fractional Preferred Shares. In lieu of fractional Preferred Shares, the Company may elect to (i) utilize a depository arrangement as provided by the terms of the Preferred Shares or (ii) in the case of a fraction of a Preferred Share (other than one one-thousandth (1/1,000th) of a Preferred Share or any integral multiple thereof), pay to the registered holders of Right Certificates at the time such Rights are exercised as herein provided an amount in cash equal to the same fraction of the current Market Value of one Preferred Share, if any are outstanding and publicly traded (or the Formula Number times the current Market Value of one share of Common Stock if the Preferred Shares are not outstanding and publicly traded). For purposes of this Section 15(b), the current Market Value of a Preferred Share (or share of Common Stock) shall be the closing price of a Preferred Share (or share of Common Stock) (as determined pursuant to the second and third sentences of the definition of Market Value contained in Section 1) for the Trading Day immediately prior to the date of such exercise. If, as a result of an adjustment made pursuant to Section 12(a), the holder of any Right thereafter exercised shall become entitled to receive any securities other than Preferred Shares, the provisions of this Section 15(b) shall apply, as nearly as reasonably may be, on like terms to such other securities. (c) The Company may, but shall not be required to, issue fractions of Common Stock upon exchange of Rights pursuant to Section 11(b), or to distribute certificates that evidence fractional Common Stock. In lieu of such fractional Common Stock, the Company may pay to the registered holders of the Right Certificates with regard to which such fractional Common Stock would otherwise be issuable an amount in cash equal to the same fraction of the current Market Value of one share of Common Stock as of the date on which a Person became an Acquiring Person.

30 (d) The holder of Rights by the acceptance of the Rights expressly waives his right to receive any fractional Rights or any fractional shares upon exercise of a Right except as provided in this Section 15. SECTION 16. Rights of Action. (a) All rights of action in respect ----------------- of this Rights Agreement are vested in the respective registered holders of the Right Certificates (or, prior to the Distribution Date, the registered holders of the Common Shares); and any registered holder of any Right Certificate (or, prior to the Distribution Date, of the Common Shares), without the consent of the Rights Agent or of the holder of any other Right Certificate (or, prior to the Distribution Date, of the Common Shares) may, in his own behalf and for his own benefit, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce, or otherwise act in respect of, his right to exercise the Rights evidenced by such Right Certificate in the manner provided in such Right Certificate and in this Rights Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Rights Agreement and shall be entitled to specific performance of the obligations of any Person under, and injunctive relief against actual or threatened violations of the obligations of any Person subject to, this Rights Agreement. (b) Any holder of Rights who prevails in an action to enforce the provisions of this Rights Agreement shall be entitled to recover the reasonable costs and expenses, including attorneys' fees, incurred in such action. SECTION 17. Transfer and Ownership of Rights and Right Certificates. -------------------------------------------------------- (a) Prior to the Distribution Date, the Rights shall be transferable only in connection with the transfer of the Common Shares and the Right associated with each Common Share shall, subject to the proviso set forth in Section 3(c), be automatically transferred upon the transfer of each Common Share. (b) After the Distribution Date, the Right Certificates shall be transferable, subject to Section 7(e), only on the registry books of the Rights Agent if surrendered at the principal office of the Rights Agent, duly endorsed or accompanied by a proper instrument of transfer. (c) The Company and the Rights Agent may deem and treat the Person in whose name a Right Certificate (or,

31 prior to the Distribution Date, the associated Common Shares certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Right Certificates or the associated certificate for Common Shares made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent shall be affected by any notice to the contrary.

In case, at the time such successor Rights Agent shall succeed to the agency created by this Rights Agreement, any of the Right Certificates shall have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Right Certificates so countersigned; and, in case at that time any of the Right Certificates shall not have been countersigned, any succes sor Rights Agent may countersign such Right Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Right Certificates shall have the full force provided in the Right Certificates and in this Rights Agreement.

SECTION 21. Duties of Rights Agent. The Rights Agent undertakes the ----------------------- duties and obligations imposed by this Rights Agreement upon the following terms and conditions, by all of which the Company and the holders of Right Certificates (or, prior to the Distribution Date, of the Common Shares), by their acceptance thereof, shall be bound: (a) The Rights Agent may consult with legal counsel (who may be legal counsel for the Company), and the opinion of such counsel shall be full and complete authorization and protection to the Rights Agent as to any action

33 taken, suffered or omitted by it in good faith and in accordance with such opinion. (b) Whenever in the performance of its duties under this Rights Agreement the Rights Agent shall deem it necessary or desirable that any fact or matter (including the identity of any Acquiring Person) be proved or established by the Company prior to taking, refraining from taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by any one of the Chairman of the Board, the Chief Executive Officer, the Chief Financial Officer, a Vice President (whether preceded by any additional title), the Treasurer or the Secretary of the Company and delivered to the Rights Agent; and such certificate shall be full authorization to the Rights Agent for any action taken or suffered in good faith by it under the provisions of this Rights Agreement in reliance upon such certificate. (c) The Rights Agent shall be liable hereunder only for its own negligence, bad faith or wilful misconduct. (d) The Rights Agent shall not be liable for or by reason of any of the statements of fact or recitals contained in this Rights Agreement or in the Right Certificates (except as to its countersignature thereof) or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by the Company only. (e) The Rights Agent shall not be under any responsibility in respect of the validity of this Rights Agreement or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Right Certificate (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Rights Agreement or in any Right Certificate; nor shall it be responsible for any adjustment required under the provisions of Section 11 or 12 or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights evidenced by Right Certificates after actual notice of any such adjustment); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Preferred Shares or shares of Common Stock to be issued pursuant to this Rights Agreement or any Right Certificate

34 or as to whether any Preferred Shares or shares of Common Stock will, when so issued, be validly authorized and issued, fully paid and nonassessable. (f) The Company agrees that it shall perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Rights Agreement. (g) The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from any one of the Chairman of the Board, the Chief Executive Officer, the Chief Financial Officer, a Vice President (whether preceded by any additional title), the Treasurer or the Secretary of the Company, in connection with its duties and it shall not be liable for any action taken or suffered to be taken by it in good faith in accordance with instructions of any such officer. (h) The Rights Agent and any stockholder, director, officer or employee of the Rights Agent may buy, sell or deal in any of the Rights or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not the Rights Agent under this Rights Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Company or for any other legal entity. (i) The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct provided reasonable care was exercised in the selection and continued employment thereof. (j) The Company shall indemnify the Rights Agent for, and hold it harmless against, any loss, liability, claim or expense ("Loss") arising out of or in connection with its duties under this Agreement, including then costs and expenses of defending itself against any Loss, unless such Loss shall have been determined by a court of competent jurisdiction to be a result of the Rights Agent's gross

35 negligence or intentional misconduct. In no case, however, will the Rights Agent be liable for special, indirect, incidental or consequential loss or damages of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the possibility of such damages. The Rights Agent shall promptly notify the Company, by letter or by facsimile confirmed by letter, of the assertion of any action, proceeding, suit or claim against the Rights Agent, promptly after the Rights Agent shall have notice of any such assertion of an action, proceeding, suit or claim or have been served with the summons or other first legal process giving information as to the nature and basis of the action, proceeding, suit or claim. The Company shall be entitled to participate at its own expense in the defense of any such action, proceeding, suit or claim, and, if the Company so elects, the Company shall assume the defense of any such action, proceeding, suit or claim. In the event that the Company assumes such defense, the Company shall not thereafter be liable for the fees and expenses of any additional counsel retained by the Rights Agent, so long as the Company shall retain counsel satisfactory to the Rights Agent, in the exercise of its reasonable judgment, to defend such action, proceeding, suit or claim. The Rights Agent agrees not to settle any litigation in connection with any action, proceeding, suit or claim with respect to which it may seek indemnification from the Company without the prior written consent of the Company. The obligations of the Company under this section shall survive the termination of this Agreement. SECTION 22. Change of Rights Agent. The Rights Agent or any ----------------------- successor Rights Agent may resign and be discharged from its duties under this Rights Agreement upon 30 days' notice in writing mailed to the Company and to each transfer agent of the Common Shares and the Preferred Shares by registered or certified mail, and to the holders of the Right Certificates (or, prior to the Distribution Date, of the Common Shares) by first-class mail. The Company may remove the Rights Agent or any successor Rights Agent upon 30 days' notice in writing, mailed to the Rights Agent or successor Rights Agent, as the case may be, and to each transfer agent of the Common Shares and the Preferred Shares by registered or certified mail, and to the holders of the Right Certificates (or, prior to the Distribution Date, of the Common Shares) by first-class mail. If the Rights Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Rights Agent. If the Company shall fail to make such appointment within a period of 30 days after giving notice of such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapaci-

36 tated Rights Agent or by the holder of a Right Certificate (or, prior to the Distribution Date, of the Common Shares) (who shall, with such notice, submit his Right Certificate or, prior to the Distribution Date, the certificate representing his Common Shares, for inspection by the Company), then the registered holder of any Right Certificate (or, prior to the Distribution Date, of the Common Shares) may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be a corporation organized and doing business under the laws of the United States or of the State of New York (or of any other state of the United States so long as such corporation is authorized to conduct a stock transfer or corporate trust business in the State of New York), in good standing, having a principal office in the State of New York, which is authorized under such laws to exercise stock transfer or corporate trust powers and is subject to supervision or examination by Federal or state authority and which has at the time of its appointment as Rights Agent a combined capital and surplus of at least $50,000,000; provided that the -------- principal transfer agent for the Common Shares shall in any event be qualified to be the Rights Agent. After appointment, the successor Rights Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Shares and the Preferred Shares, and mail a notice thereof in writing to the registered holders of the Right Certificates (or, prior to the Distribution Date, of the Common Shares). Failure to give any notice provided for in this Section 22, however, or any defect therein shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be. SECTION 23. Issuance of Additional Rights and Right Certificates. ----------------------------------------------------- Notwithstanding any of the provisions of this Rights Agreement or of the Rights to the contrary, the Company may, at its option, issue new Right Certificates evidencing Rights in such form as may be approved by its Board of Directors to reflect any adjustment or change made in accordance with the provisions of this Rights Agreement. In addition, in connection with the issuance or sale of

37 Common Shares following the Distribution Date and prior to the earlier of the Redemption Date and the Expiration Date, the Company (a) shall, with respect to Common Shares so issued or sold pursuant to the exercise of stock options or under any employee plan or arrangement, or upon the exercise, conversion or exchange of securities, notes or debentures issued by the Company, and (b) may, in any other case, if deemed necessary or appropriate by the Board of Directors of the Company, issue Right Certificates representing the appropriate number of Rights in connection with such issuance or sale; provided, however, that (i) no -------- ------- such Right Certificate shall be issued if, and to the extent that, the Company shall be advised by counsel that such issuance would create a significant risk of material adverse tax consequences to the Company or the Person to whom such Right Certificate would be issued, (ii) no such Right Certificate shall be issued if, and to the extent that, appropriate adjustment shall otherwise have been made in lieu of the issuance thereof and (iii) no such Right Certificate shall be issued to an Acquiring Person or an Affiliate or Associate of an Acquiring Person. SECTION 24. Redemption and Termination. (a) The Board of Directors --------------------------- of the Company may, at its option, at any time prior to the earlier of (i) such time as a Person becomes an Acquiring Person and (ii) the Expiration Date, order the redemption of all, but not fewer than all, the then outstanding Rights at the Redemption Price (the date of such redemption being the "Redemption Date"), and the Company, at its option, may pay the Redemption Price either in cash or Common Stock or other securities of the Company deemed by the Board of Directors of the Company, in the exercise of its sole discretion, to be at least equivalent in value to the Redemption Price. (b) Immediately upon the action of the Board of Directors of the Company ordering the redemption of the Rights, and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price. Within 10 Business Days after the action of the Board of Directors of the Company ordering the redemption of the Rights, the Company shall give notice of such redemption to the holders of the then outstanding Rights by mailing such notice to all such holders at their last addresses as they appear upon the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the transfer agent for the Common Shares. Each such notice of redemption shall state the method by which payment of the Redemption Price will be made. The notice, if mailed in the manner herein

38 provided, shall be conclusively presumed to have been duly given, whether or not the holder of Rights receives such notice. In any case, failure to give such notice by mail, or any defect in the notice, to any particular holder of Rights shall not affect the sufficiency of the notice to other holders of Rights. SECTION 25. Notices. Notices or demands authorized by this Rights -------- Agreement to be given or made by the Rights Agent or by the holder of a Right Certificate (or, prior to the Distribution Date, of the Common Shares) to or on the Company shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed (until another address is filed in writing with the Rights Agent) as follows: Crown Castle International Corp. 510 Bering Drive Suite 500 Houston, TX 77057 Attention: Corporate Secretary Subject to the provisions of Section 22, any notice or demand authorized by this Rights Agreement to be given or made by the Company or by the holder of a Right Certificate (or, prior to the Distribution Date, of the Common Shares) to or on the Rights Agent shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed (until another address is filed in writing with the Company) as follows: ChaseMellon Shareholder Services, L.L.C. 2323 Bryan St., Suite 2300 Dallas, TX 75201 Attention: Timothy D. Oliver - Relationship Manager Notices or demands authorized by this Rights Agreement to be given or made by the Company or the Rights Agent to any holder of a Right Certificate (or, prior to the Distribution Date, of the Common Shares) shall be sufficiently given or made if sent by first-class mail, postage prepaid, addressed to such holder at the address of such holder as shown on the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the transfer agent for the Common Shares. SECTION 26. Supplements and Amendments. At any time prior to the --------------------------- time any person becomes an Acquiring Person, and subject to the last sentence of this Section 26, the Company may, and the Rights Agent shall if the Company

39 so directs, supplement or amend any provision of this Rights Agreement (including the date on which the Expiration Date or the Distribution Date shall occur, the amount of the Purchase Price, the definition of "Acquiring Person" or the time during which the Rights may be redeemed pursuant to Section 24) without the approval of any holder of the Rights. From and after the Distribution Date, and subject to applicable law, the Company may, and the Rights Agent shall if the Company so directs, amend this Rights Agreement without the approval of any holders of Right Certificates (a) to cure any ambiguity or to correct or supplement any provision contained herein which may be defective or inconsistent with any other provision of this Rights Agreement or (b) to make any other provisions in regard to matters or questions arising hereunder which the Company may deem necessary or desirable and which shall not adversely affect the interests of the holders of Right Certificates (other than an Acquiring Person or an Affiliate or Associate of an Acquiring Person). Any supplement or amendment adopted during any period after any Person has become an Acquiring Person but prior to the Distribution Date shall be null and void unless such supplement or amendment could have been adopted under the prior sentence from and after the Distribution Date. Any supplement or amendment to this Rights Agreement duly approved by the Company that does not amend Sections 19, 20, 21 or 22 in a manner adverse to the Rights Agent shall become effective immediately upon execution by the Company, whether or not also executed by the Rights Agent. In addition, notwithstanding anything to the contrary contained in this Rights Agreement, no supplement or amendment to this Rights Agreement shall be made which reduces the Redemption Price (except as required by Section 12(a)). SECTION 27. Successors. All the covenants and provisions of this ----------- Rights Agreement by or for the benefit of the Company or the Rights Agent shall bind and inure to the benefit of their respective successors and assigns hereunder. SECTION 28. Benefits of Rights Agreement; Determinations and Actions -------------------------------------------------------- by the Board of Directors, etc. (a) Nothing in this Rights Agreement shall be - ------------------------------- construed to give to any Person other than the Company, the Rights Agent and the registered holders of the Right Certificates (or, prior to the Distribution Date, of the Common Shares) any legal or equitable right, remedy or claim under this Rights Agreement; but this Rights Agreement shall be for the sole and exclusive benefit of the Company, the Rights Agent and the registered holders of the Right Certificates (or, prior to the Distribution Date, of the Common Shares).

40 (b) Except as explicitly otherwise provided in this Rights Agreement, the Board of Directors of the Company shall have the exclusive power and authority to administer this Rights Agreement and to exercise all rights and powers specifically granted to the Board of Directors of the Company or to the Company, or as may be necessary or advisable in the administration of this Rights Agreement, including the right and power to (i) interpret the provisions of this Rights Agreement and (ii) make all determinations deemed necessary or advisable for the administration of this Rights Agreement (including a determination to redeem or not redeem the Rights or to amend this Rights Agreement and a determination of whether there is an Acquiring Person). (c) Nothing contained in this Rights Agreement shall be deemed to be in derogation of the obligation of the Board of Directors of the Company to exercise its fiduciary duty. Without limiting the foregoing, nothing contained herein shall be construed to suggest or imply that the Board of Directors shall not be entitled to reject any tender offer or other acquisition proposal, or to recommend that holders of Common Shares reject any tender offer, or to take any other action (including the commencement, prosecution, defense or settlement of any litigation and the submission of additional or alternative offers or other proposals) with respect to any tender offer or other acquisition proposal that the Board of Directors believes is necessary or appropriate in the exercise of such fiduciary duty. SECTION 29. Severability. If any term, provision, covenant or ------------- restriction of this Rights Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Rights Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated. SECTION 30. Governing Law. This Rights Agreement and each Right -------------- Certificate issued hereunder shall be deemed to be a contract made under the law of the State of Delaware and for all purposes shall be governed by and construed in accordance with the law of such State applicable to contracts to be made and performed entirely within such State; provided, however, that all provisions regarding the rights, duties and obligations of the Rights Agent shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed entirely with such State.

41 SECTION 31. Counterparts; Effectiveness. This Rights Agreement may ---------------------------- be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

CROWN CASTLE INTERNATIONAL CORP., by _____________________________ Name: Title: CHASEMELLON SHAREHOLDER SERVICES, L.L.C., by _____________________________ Name: Title:

CERTIFICATE OF THE VOTING POWERS, DESIGNATIONS, PREFERENCES AND RELATIVE PARTICIPATING, OPTIONAL AND OTHER SPECIAL RIGHTS AND QUALIFICATIONS, LIMITATIONS OR RESTRICTIONS OF SERIES A PARTICIPATING CUMULATIVE PREFERRED STOCK OF CROWN CASTLE INTERNATIONAL CORP. Pursuant to Section 151 of the General Corporation Law of the State of Delaware, Crown Castle International Corp. (the "Company"), a corporation organized and existing under the General Corporation Law of the State of Delaware, in accordance with the provisions of Section 103 thereof, DOES HEREBY CERTIFY: That, pursuant to the authority conferred upon the Board of Directors of the Company by Article IV of the Amended and Restated Certificate of Incorporation of the Company (the "Charter"), the Board of Directors (the "Board") of the Company on August 20, 1998, adopted the following resolution: RESOLVED, that, pursuant to the authority vested in the Board of Directors of the Company in accordance with the provisions of the Amended and Restated Certificate of Incorporation of the Company and the provisions of Section 151(g) of the General Corporation Law of the State of Delaware, the issuance of a series of Preferred Stock, par value $0.01 per share (the "Preferred Stock"), which shall consist of 2,000,000 of the shares of Preferred Stock which the Company has authority to issue, is authorized, and the Board hereby fixes the voting powers, preferences and relative, participating, optional and other special rights of the shares of such series, and the qualifications, limitations or restrictions thereof are hereby amended and restated to read in their entirety (in addition to the designation, preferences and relative, participating and other special rights, and the qualifications, limitations or restrictions thereof, set forth in the Amended and Restated Certificate of Incorporation, as amended, which are applicable to the Preferred Stock of all series) as follows: SECTION 1. Designation and Number of Shares. The shares of such --------------------------------- series shall be designated as "Series A Participating Cumulative Preferred Stock" (the "Series A Preferred Stock"). The number of shares initially constituting the Series A Preferred Stock shall be 2,000,000; provided, however, -------- ------- that, if more than a total of 2,000,000 shares of Series A Preferred Stock shall be issuable upon the

2 exercise of Rights (the "Rights") issued pursuant to the Rights Agreement dated as of August 21, 1998, between the Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent (the "Rights Agreement"), the Board of Directors of the Company, pursuant to Section 151(g) of the General Corporation Law of the State of Delaware, shall direct by resolution or resolutions that a certificate be properly executed, acknowledged, filed and recorded, in accordance with the provisions of Section 103 thereof, providing for the total number of shares of Series A Preferred Stock authorized to be issued to be increased (to the extent that the Charter then permits) to the largest number of whole shares (rounded up to the nearest whole number) issuable upon exercise of such Rights. SECTION 2. Dividends or Distributions. (a) Subject to the superior -------------------------- rights of the holders of shares of any other series of Preferred Stock or other class of capital stock of the Company ranking superior to the shares of Series A Preferred Stock with respect to dividends, the holders of shares of the Series A Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors, out of the assets of the Company legally available therefor, (1) quarterly dividends payable in cash on the 1st day of February, May, August and November in each year, or such other dates as the Board of Directors of the Company shall approve (each such date being referred to herein as a "Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or a fraction of a share of Series A Preferred Stock, in the amount of $[ ] per whole share (rounded to the nearest cent) less the amount of all cash dividends declared on the Series A Preferred Stock pursuant to the following clause (2) since the immediately preceding Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Preferred Stock (the total of which shall not, in any event, be less than zero) and (2) dividends payable in cash on the payment date for each cash dividend declared on the Common Shares in an amount per whole share (rounded to the nearest cent) equal to the Formula Number (as hereinafter defined) then in effect times the cash dividends then to be paid on each Common Share. In addition, if the Company shall pay any dividend or make any distribution on the Common Shares payable in assets, securities or other forms of noncash consideration (other than dividends or distributions solely in Common Shares), then, in each such case, the Company shall simultaneously pay or make on each outstanding whole share of Series A Preferred Stock a dividend or distribution in like kind equal to the Formula Number then in effect times such dividend or distribution on each Common Share. As used

3 herein, the "Formula Number" shall be 1,000; provided, however, that, if at any -------- ------- time after August 21, 1998, the Company shall (i) declare or pay any dividend on the Common Shares payable in shares or make any distribution on the Common Shares in Common Shares, (ii) subdivide (by a stock split or otherwise) the outstanding shares into a larger number of Common Shares or (iii) combine (by a reverse stock split or otherwise) the outstanding Common Shares into a smaller number of Common Shares, then in each such event the Formula Number shall be adjusted to a number determined by multiplying the Formula Number in effect immediately prior to such event by a fraction, the numerator of which is the number of Common Shares that are outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that are outstanding immediately prior to such event (and rounding the result to the nearest whole number); and provided further that, if at any time after August ---------------- 21, 1998, the Company shall issue any shares of its capital stock in a merger, reclassification, or change of the outstanding Common Shares, then in each such event the Formula Number shall be appropriately adjusted to reflect such merger, reclassification or change so that each share of Preferred Stock continues to be the economic equivalent of a Formula Number of Common Shares prior to such merger, reclassification or change. (b) The Company shall declare a dividend or distribution on the Series A Preferred Stock as provided in Section 2(a) immediately prior to or at the same time it declares a dividend or distribution on the Common Shares (other than a dividend or distribution solely in Common Shares); provided, however, -------- ------- that, in the event no dividend or distribution (other than a dividend or distribution in Common Shares) shall have been declared on the Common Shares during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of $1 per share on the Series A Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date. The Board of Directors may fix a record date for the determination of holders of shares of Series A Preferred Stock entitled to receive a dividend or distribution declared thereon, which record date shall be the same as the record date for any corresponding dividend or distribution on the Common Shares. (c) Dividends shall begin to accrue and be cumulative on outstanding shares of Series A Preferred Stock from and after the Quarterly Dividend Payment Date next preceding the date of original issue of such shares of Series A Preferred Stock; provided, however, that dividends on such shares which are -------- ------- originally issued after the record date for

4 the determination of holders of shares of Series A Preferred Stock entitled to receive a quarterly dividend and on or prior to the next succeeding Quarterly Dividend Payment Date shall begin to accrue and be cumulative from and after such Quarterly Dividend Payment Date. Notwithstanding the foregoing, dividends on shares of Series A Preferred Stock which are originally issued prior to the record date for the determination of holders of shares of Series A Preferred Stock entitled to receive a quarterly dividend on the first Quarterly Dividend Payment Date shall be calculated as if cumulative from and after the last day of the fiscal quarter next preceding the date of original issuance of such shares. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. (d) So long as any shares of the Series A Preferred Stock are outstanding, no dividends or other distributions shall be declared, paid or distributed, or set aside for payment or distribution, on the Common Shares unless, in each case, the dividend required by this Section 2 to be declared on the Series A Preferred Stock shall have been declared. (e) The holders of the shares of Series A Preferred Stock shall not be entitled to receive any dividends or other distributions except as provided herein. SECTION 3. Voting Rights. The holders of shares of Series A -------------- Preferred Stock shall have the following voting rights: (a) Each holder of Series A Preferred Stock shall be entitled to a number of votes equal to the Formula Number then in effect, for each share of Series A Preferred Stock held of record on each matter on which holders of the Common Shares or stockholders generally are entitled to vote, multiplied by the maximum number of votes per share which any holder of the Common Shares or stockholders generally then have with respect to such matter (assuming any holding period or other requirement to vote a greater number of shares is satisfied). (b) Except as otherwise provided herein, by the Charter or by applicable law, the holders of shares of Series A Preferred Stock and the holders of shares of Common Stock (and any other capital stock of the Company at the time entitled thereto) shall vote together as one class for the election of directors of the Company and on all other matters

5 submitted to a vote of stockholders of the Company except that while holders of shares of Series A Preferred Stock, voting as a class, are entitled to elect two directors as provided in the Charter, they shall not be entitled to participate with the Common Stock (or any other capital stock as aforesaid) in the election of any other directors. (c) Except as provided herein, in Section 11 or by applicable law, holders of Series A Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for authorizing or taking any corporate action. SECTION 4. Certain Restrictions. (a) Whenever quarterly dividends --------------------- or other dividends or distributions payable on the Series A Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series A Preferred Stock outstanding shall have been paid in full, the Company shall not (i) declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock; (ii) declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, except dividends paid ratably on the Series A Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled; (iii) redeem or purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock; provided that the Company may at any time redeem, purchase or otherwise -------- acquire shares of any such parity stock in exchange for shares of any stock of the Company ranking junior (either as to dividends or upon dissolution, liquidation or winding up) to the Series A Preferred Stock; or (iv) purchase or otherwise acquire for consideration any shares of Series A Preferred Stock, or any shares of

6 stock ranking on a parity with the Series A Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of such shares upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes.

(a) The shares of Series ------------------------------ A Preferred Stock shall not be subject to redemption by the Company or at the option of any holder of Series A Preferred Stock; provided, however, that the -------- ------- Company may purchase or otherwise acquire outstanding shares of Series A Preferred Stock in the open market or by offer to any holder or holders of shares of Series A Preferred Stock.

SECTION 10. Reacquired Shares. Any shares of Series A Preferred ------------------ Stock purchased or otherwise acquired by the Company in any manner whatsoever shall be retired and canceled promptly after the acquisition thereof. All such shares shall upon their cancelation become authorized but unissued shares of Preferred Stock, without designation as to series until such shares are once more designated as part of a

8 particular series by the Board of Directors pursuant to the provisions of the Charter. SECTION 11. Amendment. None of the powers, preferences and relative, ---------- participating, optional and other special rights of the Series A Preferred Stock as provided herein, in the Company's by-laws or in the Charter shall be amended in any manner which would alter or change the powers, preferences, rights or privileges of the holders of Series A Preferred Stock so as to affect them adversely without the affirmative vote of the holders of at least 66-2/3% of the outstanding shares of Series A Preferred Stock, voting as a separate class; provided, however, that no such amendment approved by the holders of at least - -------- ------- 66-2/3% of the outstanding shares of Series A Preferred Stock shall be deemed to apply to the powers, preferences, rights or privileges of any holder of shares of Series A Preferred Stock originally issued upon exercise of the Rights after the time of such approval without the approval of such holder. IN WITNESS WHEREOF, the Company has caused this Certificate to be duly executed in its corporate name on this 21st day of August, 1998.

SECTION 2. HOLDERS A Person is deemed to be a holder of Transfer Restricted Securities (each, a "Holder") whenever such Person owns Transfer Restricted Securities. ------ SECTION 3. REGISTERED EXCHANGE OFFER (a) Unless the Exchange Offer shall not be permitted by applicable federal law (after the procedures set forth in Section 6(a)(i) below have been complied with), the Company shall (i) cause the Exchange Offer Registration Statement to be filed with the Commission as soon as practicable after the Closing Date (the "Exchange Offer Filing Date"), but in no event later than 60 days after the -------------------------- Closing Date (such 60th day being the "Filing Deadline"), (ii) use all --------------- commercially reasonable efforts to cause such Exchange Offer Registration Statement to become effective at the earliest possible time, but in no event later than 150 days after the Closing Date (such 150th day being the "Effectiveness Deadline"), (iii) in connection with the foregoing, (A) file all ---------------------- pre-effective amendments to such Exchange Offer Registration Statement as may be necessary in order to cause it to become effective, (B) file, if applicable, a post-effective amendment to such Exchange Offer Registration Statement pursuant to Rule 430A under the Act and (C) cause all necessary filings, if any, in connection with the registration and qualification of the New Preferred Stock or the New Exchange Debentures, as the case may be, to be made under the Blue Sky laws of such jurisdictions as are necessary to permit Consummation of the 4

Exchange Offer and (iv) upon the effectiveness of such Exchange Offer Registration Statement, commence and Consummate the Exchange Offer. The Exchange Offer shall be on the appropriate form permitting registration of the New Preferred Stock or the New Exchange Debentures, as the case may be, to be offered in exchange for the Preferred Stock or the Exchange Debentures, respectively, that are Transfer Restricted Securities and to permit resales of New Preferred Stock or New Exchange Debentures, as the case may be, by Broker- Dealers that tendered into the Exchange Offer for Preferred Stock or Exchange Debentures, respectively, that such Broker-Dealer acquired for its own account as a result of market making activities or other trading activities (other than Preferred Stock or, if issued in exchange therefor, Exchange Debentures acquired directly from the Company or any of its Affiliates) as contemplated by Section 3(c) below. (b) The Company shall use its best efforts to cause the Exchange Offer Registration Statement to be effective continuously, and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to Consummate the Exchange Offer; provided, however, that in no event shall such period be less than 20 Business Days. The Company shall cause the Exchange Offer to comply with all applicable federal and state securities laws. No securities other than the New Preferred Stock or, if issued in exchange therefor, the New Exchange Debentures shall be included in the Exchange Offer Registration Statement. The Company shall use its best efforts to cause the Exchange Offer to be Consummated on the earliest practicable date after the Exchange Offer Registration Statement has become effective, but in no event later than 30 Business Days thereafter. (c) The Company shall include a "Plan of Distribution" section in the Prospectus contained in the Exchange Offer Registration Statement and indicate therein that any Broker-Dealer that holds Transfer Restricted Securities that were acquired for the account of such Broker-Dealer as a result of market-making activities or other trading activities (other than Transfer Restricted Securities acquired directly from the Company or any Affiliate of the Company), may exchange such Transfer Restricted Securities pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed to be an "underwriter" within the meaning of the Act and must, therefore, deliver a prospectus meeting the requirements of the Act in connection with its initial sale of any New Preferred Stock or New Exchange Debentures, as the case may be, received by such Broker- Dealer in the Exchange Offer and that the Prospectus contained in the Exchange Offer Registration Statement may be used to satisfy such prospectus delivery requirement. Such "Plan of Distribution" section shall also contain all other information with respect to such sales by such Broker-Dealers that the Commission may require in order to permit such sales pursuant thereto, but such "Plan of Distribution" shall not name any such Broker-Dealer or disclose the amount of Transfer Restricted Securities held by any such Broker-Dealer, except to the extent required by the Commission as a result of a change in policy, rules or regulations after the date of this Agreement. To the extent necessary to ensure that the Exchange Offer Registration Statement is available for sales of New Preferred Stock or New Exchange Debentures, as the case may be, by Broker-Dealers, the Company agrees to use its best efforts to keep the Exchange Offer 5

Registration Statement continuously effective, supplemented and amended as required by the provisions of Section 6(c) hereof and in conformity with the requirements of this Agreement, the Act and the policies, rules and regulations of the Commission as announced from time to time, for a period of 180 days from the date on which the Exchange Offer is Consummated, or such shorter period as will terminate when all Transfer Restricted Securities held by such Broker- Dealers covered by such Registration Statement have been sold pursuant thereto (unless such period is extended pursuant to Section 6(c)(i) below). The Company shall promptly provide sufficient copies of the latest version of such Prospectus to such Broker-Dealers promptly upon request, and in no event later than one day after such request, at any time during such period. SECTION 4. SHELF REGISTRATION (a) Shelf Registration. If (i) the Exchange Offer is not permitted by ------------------ applicable law (after the Company has complied with the procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of Transfer Restricted Securities shall notify the Company within 20 Business Days following the Consummation of the Exchange Offer that (A) such Holder was prohibited by law or Commission policy from participating in the Exchange Offer or (B) such Holder may not resell the New Preferred Stock or New Exchange Debentures, as the case may be, acquired by it in the Exchange Offer to the public without delivering a prospectus and the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder or (C) such Holder is a Broker-Dealer and holds Preferred Stock or, if issued in exchange therefor, Exchange Debentures acquired directly from the Company or any of its Affiliates, then the Company shall: (x) cause to be filed, on or prior to 45 days after the earlier of (i) the date on which the Company determines that the Exchange Offer Registration Statement cannot be filed as a result of clause (a)(i) above and (ii) the date on which the Company receives the notice specified in clause (a) (ii) above, (such earlier date, the "Filing Deadline"), a shelf registration statement --------------- pursuant to Rule 415 under the Act (which may be an amendment to the Exchange Offer Registration Statement (the "Shelf Registration Statement")), relating to ---------------------------- all Transfer Restricted Securities, and (y) shall use all commercially reasonable efforts to cause such Shelf Registration Statement to become effective on or prior to 90 days after the Filing Deadline (such 90th day the "Effectiveness Deadline"). ---------------------- If, after the Company has filed an Exchange Offer Registration Statement that satisfies the requirements of Section 3(a) above, the Company is required to file and make effective a Shelf Registration Statement solely because the Exchange Offer is not permitted under applicable federal law, then the filing of the Exchange Offer Registration Statement shall be deemed to satisfy the requirements of clause (x) above; provided that, in such event, the Company shall remain obligated to meet the Effectiveness Deadline set forth in clause (y). The Company shall use its best efforts to keep any Shelf Registration Statement required by this Section 4(a) continuously effective, supplemented and amended as required by and 6

subject to the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for sales of Transfer Restricted Securities by the Holders thereof entitled to the benefit of this Section 4(a), and to ensure that it conforms with the requirements of this Agreement, the Act and the policies, rules and regulations of the Commission as announced from time to time, for a period of at least two years (as extended pursuant to Section 6(c)(i)) following the date on which such Shelf Registration Statement first becomes effective under the Act, or such shorter period as will terminate when all Transfer Restricted Securities covered by such Registration Statement (i) have been sold pursuant thereto or (ii) are no longer restricted Securities (as defined in Rule 144 under the Act). (b) Provision by Holders of Certain Information in Connection with the ------------------------------------------------------------------ Shelf Registration Statement. No Holder of Transfer Restricted Securities may - ---------------------------- include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within 20 days after receipt of a request therefor, the information specified in Item 507 or 508 of Regulation S-K, as applicable, of the Act for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. No Holder of Transfer Restricted Securities shall be entitled to liquidated damages pursuant to Section 5 hereof unless and until such Holder shall have provided all such information. Each selling Holder agrees to promptly furnish additional information required to be disclosed in order to make the information previously furnished to the Company by such Holder not materially misleading. SECTION 5. LIQUIDATED DAMAGES (a) If (i) any Registration Statement required by this Agreement is not filed with the Commission on or prior to the applicable Filing Deadline, (ii) any such Registration Statement has not been declared effective by the Commission on or prior to the applicable Effectiveness Deadline, (iii) the Exchange Offer has not been Consummated within 30 Business Days after the Exchange Offer Registration Statement is first declared effective by the Commission or (iv) any Registration Statement required by this Agreement is filed and declared effective but shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded immediately by a post-effective amendment to such Registration Statement that cures such failure and that is itself declared effective immediately (except as permitted in paragraph (b); such period of time during which any such Registration Statement is not effective or any such Registration Statement or the related Prospectus is not usable being referred to as a Blackout Period") (each such event referred to in clauses (i) through (iv), a "Registration Default"), then the Company hereby -------------------- agrees to pay to each Holder of Transfer Restricted Securities affected thereby liquidated damages in an amount equal to $.05 per week per $1,000 in liquidation preference (in the case of Stock) or principal amount (in the case of Debentures) of Transfer Restricted Securities held by such Holder for each week or portion thereof that the Registration Default continues for the first 90-day period immediately following the occurrence of such Registration Default. The amount of the liquidated damages shall increase by an additional $.05 per week per $1,000 in liquidation preference (in the case of Stock) or principal amount (in the case of Debentures) of Transfer Restricted Securities with respect to each 7

subsequent 90-day period until all Registration Defaults have been cured, up to a maximum amount of liquidated damages for all Registration Defaults of $.50 per week per $1,000 in liquidation preference (in the case of Stock) or principal amount (in the case of Debentures) of Transfer Restricted Securities. Notwithstanding anything to the contrary set forth herein, (1) upon filing of the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement), in the case of (i) above, (2) upon the effectiveness of the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement), in the case of (ii) above, (3) upon Consummation of the Exchange Offer, in the case of (iii) above, or (4) upon the filing of a post- effective amendment to the Registration Statement or an additional Registration Statement that causes the Exchange Offer Registration Statement (and/or, if applicable, the Shelf Registration Statement) to again be declared effective or made usable in the case of (iv) above, the liquidated damages payable with respect to the Transfer Restricted Securities as a result of such clause (i), (ii), (iii) or (iv), as applicable, shall cease. (b) A Registration Default referred to in Section 5(a)(iv) shall be deemed not to have occurred and be continuing in relation to a Registration Statement or the related Prospectus if (i) the Blackout Period has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related Prospectus or (y) the occurrence of other material events with respect to the Company that would need to be described in such Registration Statement or the related Prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement (including by way of filing documents under the Exchange Act which are incorporated by reference into the Registration Statement) such Registration Statement and the related Prospectus to describe such events: provided, however, that in any case if such Blackout Period occurs for a continuous period in excess of 30 days, a Registration Default shall be deemed to have occurred on the 31st day of such Blackout Period and liquidated damages shall be payable in accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured or until the Company is no longer required pursuant to this Agreement to keep such Registration Statement effective or such Registration Statement or the related Prospectus usable; provided further, however, that in no event shall the total of all Blackout Periods exceed 60 days in the aggregate in any 12-month period. All accrued liquidated damages shall be paid to the Holders entitled thereto, in the manner provided for the payment of dividends in the Certificate of Designations, on each Dividend Payment Date, as more fully set forth in the Certificate of Designations or, if the Preferred Stock has been exchanged for Exchange Debentures, in the manner provided for the payment of interest in the Exchange Indenture, on each Interest Payment Date, as more fully set forth in the Exchange Indenture and the Exchange Debentures. Liquidated damages, if any, incurred prior to December 15, 2003, may be paid, at the Company's option, by the issuance of additional shares of Preferred Stock having an aggregate liquidation preference equal to the amount of liquidated damages or, if the Preferred Stock has been exchanged for Exchange Debentures, by the issuance of additional Exchange Debentures having an aggregate principal 8

amount equal to the amount of such liquidated damages. All obligations of the Company set forth in the preceding paragraph that are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such Security shall have been satisfied in full. SECTION 6. REGISTRATION PROCEDURES (a) Exchange Offer Registration Statement. In connection with the Exchange ------------------------------------- Offer, the Company shall comply with all applicable provisions of Section 6(c) below, shall use its best efforts to effect such exchange and to permit the resale of New Preferred Stock or New Exchange Debentures, as the case may be, by Broker-Dealers that tendered in the Exchange Offer Preferred Stock or Exchange Debentures, respectively, that such Broker-Dealer acquired for its own account as a result of its market making activities or other trading activities (other than Preferred Stock or, if issued in exchange therefor, Exchange Debentures acquired directly from the Company or any of its Affiliates) being sold in accordance with the intended method or methods of distribution thereof, and shall comply with all of the following provisions: (i) If, following the date hereof there has been announced a change in Commission policy with respect to exchange offers such as the Exchange Offer, that in the reasonable opinion of counsel to the Company raises a substantial question as to whether the Exchange Offer is permitted by applicable federal law, the Company hereby agrees to seek a no-action letter or other favorable decision from the Commission allowing the Company to Consummate an Exchange Offer for such Transfer Restricted Securities. The Company hereby agrees to pursue the issuance of such a decision to the Commission staff level.

(b) Shelf Registration Statement. In connection with the Shelf ---------------------------- Registration Statement, the Company shall comply with all the provisions of Section 6(c) below and shall use its best efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof (as indicated in the information furnished to the Company pursuant to Section 4(b) hereof), and pursuant thereto the Company will prepare and file with the Commission a Registration Statement relating to the registration on any appropriate form under the Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the intended method or methods of distribution thereof within the time periods and otherwise in accordance with the provisions hereof. 10

If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from 11

qualification of the Transfer Restricted Securities under state securities or Blue Sky laws, the Company shall use its best efforts to obtain the withdrawal or lifting of such order at the earliest possible time; (iv) subject to Section 6(c)(i), if any fact or event contemplated by Section 6(c)(iii)(D) above shall exist or have occurred, prepare a supplement or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; (v) furnish to the Initial Purchasers and, if requested by any selling Holder, to such Holder, named in any Registration Statement or Prospectus in connection with such sale, if any, before filing with the Commission, copies of any Registration Statement or any Prospectus included therein or any amendments or supplements to any such Registration Statement or Prospectus (including all documents incorporated by reference after the initial filing of such Registration Statement), which documents will be subject to the review and comment of such Holders in connection with such sale, if any, for a period of at least five Business Days, and the Company will not file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus (including all such documents incorporated by reference) to which the selling Holders of the Transfer Restricted Securities covered by such Registration Statement in connection with such sale, if any, shall reasonably object within five Business Days after the receipt thereof. A selling Holder shall be deemed to have reasonably objected to such filing if such Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be filed, contains a material misstatement or omission or fails to comply with the applicable requirements of the Act; (vi) upon the reasonable request of any selling Holder, promptly prior to the filing of any document that is to be incorporated by reference into a Registration Statement or Prospectus, provide copies of such document to the selling Holders in connection with such sale, if any, make the Company's representatives available for discussion of such document and other customary due diligence matters, and include such information in such document prior to the filing thereof; (vii) in the case of any Shelf Registration, make available at reasonable times for inspection by the selling Holders participating in any disposition pursuant to such Registration Statement and any attorney or accountant retained by such selling Holders, all financial and other records, pertinent corporate documents of the Company and cause the Company's officers, directors and employees to supply all information reasonably requested by any such selling Holder, attorney or accountant in connection with such Registration Statement or any post-effective amendment thereto subsequent to the filing 12

connection with such purchase and any such loss, claim, damage or liability of such Holder or Broker-Dealer results from the fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Securities to such person, a copy of the final Prospectus if the Company has previously furnished copies thereof to such Holder of Broker-Dealer; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such Indemnified Holder. (b) Each Holder of Transfer Restricted Securities agrees, severally and not jointly, to indemnify and hold harmless the Company, and its directors and officers, and each controlling person, if any, to the same extent as the foregoing indemnity from the Company to each of the Indemnified Holders, but only with reference to information relating to such Indemnified Holder furnished in writing to the Company by such Indemnified Holder expressly for use in any Registration Statement and, subject to the limitation set forth immediately preceding this clause, shall reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability which such Holder may otherwise have the Company or any of their controlling persons. (c) In case any action shall be commenced involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the "indemnified party"), the indemnified party shall promptly notify the person ----------------- against whom such indemnity may be sought (the "indemnifying person") in writing ------------------- and the indemnifying party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the indemnified party and the payment of all fees and expenses of such counsel, as incurred (except that in the case of any action in respect of which indemnity may be sought pursuant to both Sections 8(a) and 8(b), an Indemnified Holder shall not be required to assume the defense of such action pursuant to this Section 8(c), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of the Indemnified Holder). Any indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense of such action or employ counsel reasonably satisfactory to the indemnified party or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party). In any such case, the indemnifying party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties and all such fees and 19

expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by Holders of a majority in aggregate liquidation preference of Stock or principal amount of Debentures, as the case may be, in the case of the parties indemnified pursuant to Section 8(a), and by the Company, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall indemnify and hold harmless the indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action (i) effected with its written consent or (ii) effected without its written consent if the settlement is entered into more than twenty business days after the indemnifying party shall have received a request from the indemnified party for reimbursement for the fees and expenses of counsel (in any case where such fees and expenses are at the expense of the indemnifying party) and, prior to the date of such settlement, the indemnifying party shall have failed to comply with such reimbursement request. No indemnifying party shall (i) without the prior written consent of the indemnified party, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened action in respect of which the indemnified party is or could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment includes an unconditional release of the indemnified party from all liability on claims that are or could have been the subject matter of such action or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. (d) To the extent that the indemnification provided for in this Section 8 is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Indemnified Holders, on the other hand, from their sale of Transfer Restricted Securities or (ii) if the allocation provided by clause 8(d)(i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above but also the relative fault of the Company, on the one hand, and of the Indemnified Holder, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative fault of the Company, on the one hand, and of the Indemnified Holder, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or by the Indemnified Holder, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and judgments referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 8(a), any legal or 20

other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The Company and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any matter, including any action that could have given rise to such losses, claims, damages, liabilities or judgments. Notwithstanding the provisions of this Section 8, no Holder or its related Indemnified Holders shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total received by such Holder with respect to the sale of its Transfer Restricted Securities pursuant to a Registration Statement exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders' obligations to contribute pursuant to this Section 8(d) are several in proportion to the respective aggregate liquidation preference of Stock or principal amount of Debentures constituting Transfer Restricted Securities held by each of the Holders hereunder and not joint. SECTION 9. RULE 144A The Company hereby agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding and during any period in which the Company is not subject to Section 13 or 15(d) of the Exchange Act, to make available, upon request of any Holder of Transfer Restricted Securities, to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities designated by such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A. SECTION 10. MISCELLANEOUS (a) Remedies. The Company acknowledges and agrees that any failure by the -------- Company to comply with its obligations under Sections 3 and 4 hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company's obligations under Sections 3 and 4 hereof. The Company further agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. 21

(b) No Inconsistent Agreements. The Company will not, on or after the date -------------------------- of this Agreement, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The Company has not previously entered into any agreement granting any registration rights with respect to its securities to any Person. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company's securities under any agreement in effect on the date hereof. (c) Adjustments Affecting the Stock and the Debentures. The Company will -------------------------------------------------- not take any action, or permit any change to occur, with respect to the Stock and the Debentures that would materially and adversely affect the ability of the Holders to Consummate any Exchange Offer. (d) Amendments and Waivers. The provisions of this Agreement may not be ---------------------- amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless (i) in the case of Section 5 hereof and this Section 10(d)(i), the Company has obtained the written consent of Holders of all outstanding Transfer Restricted Securities and (ii) in the case of all other provisions hereof, the Company has obtained the written consent of Holders of a majority of the outstanding aggregate liquidation preference of Stock or principal amount of Debentures, as the case may be, constituting Transfer Restricted Securities (excluding Transfer Restricted Securities held by the Company of its Affiliates). Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of Holders whose securities are being tendered pursuant to the Exchange Offer and that does not affect directly or indirectly the rights of other Holders whose securities are not being tendered pursuant to such Exchange Offer may be given by the Holders of a majority of the aggregate liquidation preference of Stock or principal amount of Debentures, as the case may be, constituting Transfer Restricted Securities subject to such Exchange Offer. (e) Third Party Beneficiary. The Holders shall be third party ----------------------- beneficiaries to the agreements made hereunder between the Company, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to the extent they may deem such enforcement necessary or advisable to protect its rights or the rights of Holders hereunder. (f) Notices. All notices and other communications provided for or ------- permitted hereunder shall be made in writing by hand-delivery, first-class mail (registered or certified, return receipt requested), telex, telecopier, or air courier guaranteeing overnight delivery: (i) if to a Holder, at the address set forth on the records of the Transfer Agent or, if the Stock has been exchanged for Debentures, of the Registrar under the Exchange Indenture, with a copy to the Exchange Trustee under the Exchange Indenture; and (ii) if to the Company: 22
