THE COMPANY We are a leading owner and operator of towers and transmission networks for wireless communications and broadcast transmission companies. As of April 30, 2000, we owned, leased or managed 10,392 towers, including 8,195 sites in the United States and Puerto Rico and 2,197 sites in the United Kingdom. We have entered into agreements, which, when completed, will provide us with over 900 additional towers in the United States in 2000. In addition, we have recently entered into an agreement which provides us with a tower portfolio of approximately 700 towers in Australia. Our customers currently include many of the world's major wireless communications and broadcast companies, including GTE Wireless, Verizon, BellSouth Mobility, Powertel, Nextel, Sprint PCS, AT&T Wireless, Triton PCS, Tritel Communications, Motorola, Cable & Wireless Optus, One Zone and the British Broadcasting Corporation. Our strategy is to use our leading domestic and international position to capture the growing opportunities to consolidate ownership and management of existing towers and other wireless and transmission infrastructure and to build and operate new towers and wireless and transmission networks and infrastructure created by: . the transfer to third parties, or outsourcing, of tower ownership and management by major wireless carriers; . the need for existing wireless carriers to expand coverage and improve capacity; . the additional demand for towers and wireless infrastructure created by new entrants into the wireless communications industry; . the privatization of state-run broadcast transmission networks; and . the introduction of new wireless technologies such as broadband data, or "3G," technology. Our main businesses are leasing antenna space on wireless and broadcast towers that can accommodate multiple tenants and operating analog and digital broadcast transmission networks and wireless networks. We also provide related services to our customers, including network design, radio frequency engineering, site acquisition, site development and construction, antenna installation and network management and maintenance. We believe that our full service capabilities are a key competitive advantage in forming strategic partnerships to acquire large concentrations of towers, or tower clusters, and in winning contracts for tower acquisitions, management and construction along with wireless and transmission network management. Our primary business in the United States is the leasing of antenna space to wireless carriers. We believe that by owning and managing large tower clusters we are able to offer customers the ability to fulfill rapidly and efficiently their network expansion plans across particular markets or regions. Our acquisition strategy has been focused on adding tower clusters to our tower portfolio. As of April 30, 2000, we had tower clusters in 34 of the 50 largest U.S. metropolitan areas, and 68 of the 100 largest U.S. metropolitan areas. Our primary business in the United Kingdom, which is conducted through Crown Castle UK Holdings Limited ("CCUK"), is the operation of television and radio broadcast transmission networks. Following the 1997 acquisition of the BBC's broadcast and tower infrastructure, we were awarded long-term contracts to provide the BBC and other broadcasters analog and digital transmission services. We also lease antenna space to wireless operators in the United Kingdom on the towers we acquired from the BBC and from various wireless carriers along with towers we have constructed. We have nationwide broadcast and wireless coverage in the United Kingdom. Our primary business in Australia is the leasing of antenna space to wireless carriers. In March 2000, a 66.7% subsidiary of ours, Crown Castle Australia Limited, or "CCAL", entered into an agreement to purchase approximately 700 towers in Australia from Cable & Wireless Optus for at total purchase price of approximately $135 million in cash (Australian $220 million). Upon completion of the Cable & Wireless Optus transaction, which we expect to close during the remainder of 2000, CCAL will own and operate a nationwide portfolio of approximately 700 towers in Australia covering over 90 percent of the population. 3

We believe our towers are attractive to a diverse range of wireless communications industries, including personal communications services, cellular, enhanced specialized mobile radio, specialized mobile radio, paging, and fixed microwave, as well as radio and television broadcasting. In the United States our major customers include GTE Wireless, Verizon, BellSouth Mobility, Powertel, Nextel, Sprint PCS, AT&T Wireless, Triton PCS, Tritel Communications and Motorola. In the United Kingdom our major customers include the BBC, Cellnet, Dolphin, NTL, ONdigital, One2One, Orange, Virgin Radio and Vodafone AirTouch. Our principal customer in Australia is Cable & Wireless Optus. We are continuing our ongoing construction program to enhance our tower portfolios. In 1999, we constructed over 900 towers. In 2000, we plan to construct approximately 1,170 towers at an estimated aggregate cost of $270 million for lease to wireless carriers such as Verizon, BellSouth Mobility, GTE Wireless and Nextel. The actual number of towers built may be outside that range depending on acquisition opportunities and potential build-to-suit contracts from large wireless carriers. Our principal executive offices are located at 510 Bering Drive, Suite 500, Houston, Texas 77057, and our telephone number is (713) 570-3000. RATIO OF EARNINGS TO FIXED CHARGES The following table sets forth our consolidated ratio of earnings to fixed charges, the deficiency of our consolidated earnings to cover fixed charges, our consolidated ratio of earnings to combined fixed charges and preferred stock dividends and the deficiency of our consolidated earnings to cover combined fixed charges and preferred stock dividends for the periods indicated.

Fixed charges consist of interest expense, the interest component of operating leases and amortization of deferred financing costs. USE OF PROCEEDS We will use the net proceeds from our sale of the securities for our general corporate purposes, which may include repaying indebtedness, making additions to our working capital, funding future acquisitions or for any other purpose we describe in the applicable prospectus supplement. We will not receive any of the proceeds from the sale of common stock that may be sold by selling stockholders. 4

DESCRIPTION OF DEBT SECURITIES The following description of the terms of the debt securities sets forth certain general terms and provisions of the debt securities to which any prospectus supplement may relate. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the debt securities so offered will be described in the prospectus supplement relating to such debt securities. Accordingly, for a description of the terms of a particular issue of debt securities, reference must be made to both the prospectus supplement relating thereto and to the following description. The debt securities will be our general obligations and may be subordinated to "Senior Indebtedness" (as defined below) we have or may incur to the extent set forth in the prospectus supplement relating to them. See "Description of Debt Securities--Subordination" below. Debt securities will be issued under an indenture between us and one or more commercial banks to be selected as trustees (collectively, the "trustee"). A copy of the form of indenture has been filed as an exhibit to the registration statement filed with the SEC. The following discussion of certain provisions of the indenture is a summary only and should not be considered a complete description of the terms and provisions of the indenture. Accordingly, the following discussion is qualified in its entirety by reference to the provisions of the indenture, including the definition of certain terms used below. General The indenture does not limit the aggregate principal amount of debt securities that can be issued under it. The debt securities may be issued in one or more series as we may authorize from time to time. You should refer to the applicable prospectus supplement for the following terms of the debt securities of the series with respect to which that prospectus supplement is being delivered: (a) the title of the debt securities of the series; (b) any limit on the aggregate principal amount of the debt securities of the series that may be authenticated and delivered under the indenture; (c) the date or dates on which the principal and premium with respect to the debt securities of the series are payable; (d) the rate or rates (which may be fixed or variable) at which the debt securities of the series shall bear interest (if any) or the method of determining such rate or rates, the date or dates from which such interest shall accrue, the interest payment dates on which such interest shall be payable or the method by which such dates will be determined, the record dates for the determination of holders thereof to whom such interest is payable (in the case of Registered Securities (as defined below)), and the basis upon which interest will be calculated if other than that of a 360- day year of twelve 30-day months; (e) the currency or currencies in which debt securities of the series shall be denominated, the place or places, if any, in addition to or instead of the corporate trust office of the trustee (in the case of Registered Securities) or the principal New York office of the trustee (in the case of Bearer Securities), where the principal, premium, and interest with respect to debt securities of the series shall be payable; (f) the price or prices at which, the period or periods within which, and the terms and conditions upon which debt securities of the series may be redeemed, in whole or in part at our option or otherwise; (g) whether debt securities of the series are to be issued as Registered Securities or Bearer Securities (as defined below) or both and, if Bearer Securities are to be issued, whether coupons will be attached to them, whether Bearer Securities of the series may be exchanged for Registered Securities of the series, and the circumstances under which and the places at which any such exchanges, if permitted, may be made; (h) if any debt securities of the series are to be issued as Bearer Securities or as one or more Global Securities (as defined below) representing individual Bearer Securities of the series, whether certain 5

The prospectus supplement will also describe any material United States federal income tax consequences or other special considerations applicable to the series of debt securities to which such prospectus supplement relates, including those applicable to (a) Bearer Securities, (b) debt securities with respect to which payments of principal, premium or interest are determined with reference to an index or formula (including changes in prices of particular securities, currencies or commodities), (c) debt securities with respect to which principal, or interest is payable in a foreign or composite currency, (d) debt securities that are issued at a discount below their stated principal amount, bearing no interest or interest at a rate that at the time of issuance is below market rates ("Original Issue Discount Debt Securities") and (e) variable rate debt securities that are exchangeable for fixed rate debt securities. Unless otherwise provided in the applicable prospectus supplement, Registered Securities may be transferred or exchanged at the office of the trustee at which its corporate trust business is principally administered in the United States or at the office of the trustee or the trustee's agent in the Borough of Manhattan, the City and State of New York, at which its corporate agency business is conducted, subject to the limitations provided in the indenture, without the payment of any service charge, other than any tax or governmental charge payable in connection therewith. Bearer Securities will be transferable only by delivery. Provisions with respect to the exchange of Bearer Securities will be described in the prospectus supplement relating to such Bearer Securities. All funds which we pay to a paying agent for the payment of principal, premium or interest with respect to any debt securities that remain unclaimed at the end of two years after such principal, premium or interest shall have become due and payable will be repaid to us, and the holders of such debt securities or any coupons appertaining thereto will thereafter look only to us for payment thereof. Global Securities The debt securities of a series may be issued in whole or in part in the form of one or more global securities. A global security is a debt security that represents, and is denominated in an amount equal to the aggregate principal amount of, all outstanding debt securities of a series, or any portion thereof, in either case having the same terms, including the same original issue date, date or dates on which principal and interest are due, and interest rate or method of determining interest. A global security will be deposited with, or on behalf of, a depositary, which will be identified in the prospectus supplement relating to such debt securities. Global securities may be issued in either registered or bearer form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities represented thereby, a global security may not be transferred except as a whole by the depositary to a nominee of the depositary, by a nominee of the depositary to the depositary or another nominee of the depositary, or by the depositary or any nominee of the depositary to a successor depositary or any nominee of such successor. 7

The specific terms of the depositary arrangement with respect to a series of debt securities will be described in the prospectus supplement relating to such debt securities. We anticipate that the following provisions will generally apply to depositary arrangements. Upon the issuance of a global security, the depositary for such global security will credit, on its book entry registration and transfer system, the respective principal amounts of the individual debt securities represented by such global security to the accounts of persons that have accounts with the depositary ("participants"). Such accounts shall be designated by the dealers or underwriters with respect to such debt securities or, if such debt securities are offered and sold directly by us or through one or more agents, by us or such agents. Ownership of beneficial interests in a global security will be limited to participants or persons that hold beneficial interests through participants. Ownership of beneficial interests in such global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the depositary (with respect to interests of participants) or records maintained by participants (with respect to interests of persons other than participants). The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limitations and laws may impair the ability to transfer beneficial interests in a global security. So long as the depositary for a global security, or its nominee, is the registered owner or holder of such global security, such depositary or nominee, as the case may be, will be considered the sole owner or holder of the individual debt securities represented by such global security for all purposes under the indenture. Except as provided below, owners of beneficial interests in a global security will not be entitled to have any of the individual debt securities represented by such global security registered in their names, will not receive or be entitled to receive physical delivery of any of such debt securities in definitive form, and will not be considered the owners or holders thereof under the Indenture. Subject to the restrictions applicable to Bearer Securities described in an applicable prospectus supplement (see "Limitations on Issuance of Bearer Securities" below), payments of principal, premium, and interest with respect to individual debt securities represented by a global security will be made to the depositary or its nominee, as the case may be, as the registered owner or holder of such global security. Neither we, the trustee, any paying agent or registrar for such debt securities or any agent of ours or the trustee's will have any responsibility or liability for (a) any aspect of the records relating to or payments made by the depositary, its nominee or any participants on account of beneficial interests in the global security or for maintaining, supervising or reviewing any records relating to such beneficial interests, (b) the payment to the owners of beneficial interests in the global security of amounts paid to the depositary or its nominee or (c) any other matter relating to the actions and practices of the depositary, its nominee or its participants. Neither we, the trustee, any paying agent or registrar for such debt securities or any agent of ours or the trustee will be liable for any delay by the depositary, its nominee or any of its participants in identifying the owners of beneficial interests in the global security, and we and the trustee may conclusively rely on, and will be protected in relying on, instructions from the depositary or its nominee for all purposes. We expect that the depositary for a series of debt securities or its nominee, upon receipt of any payment of principal, premium or interest with respect to a definitive global security representing any of such debt securities, will immediately credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global security, as shown on the records of the depositary or its nominee. We also expect that payments by participants to owners of beneficial interests in such global security held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers and registered in "street name." Such payments will be the responsibility of such participants. Receipt by owners of beneficial interests in a temporary global security of payments of principal, premium or interest with respect thereto will be subject to the restrictions described in an applicable prospectus supplement (see "Limitation on Issuance of Bearer Securities" below). 8

If the depositary for a series of debt securities is at any time unwilling, unable or ineligible to continue as depositary, we shall appoint a successor depositary. If a successor depositary is not appointed by us within 90 days, we will issue individual debt securities of such series in exchange for the global security representing such series of debt securities. In addition, we may at any time and in our sole discretion, subject to any limitations described in the prospectus supplement relating to such debt securities, determine to no longer have debt securities of a series represented by a global security and, in such event, will issue individual debt securities of such series in exchange for the global security representing such series of debt securities. Furthermore, if we so specify with respect to the debt securities of a series, an owner of a beneficial interest in a global security representing debt securities of such series may, on terms acceptable to us, the trustee, and the depositary for such global security, receive individual debt securities of such series in exchange for such beneficial interests, subject to any limitations described in the prospectus supplement relating to such debt securities. In any such instance, an owner of a beneficial interest in a global security will be entitled to physical delivery of individual debt securities of the series represented by such global security equal in principal amount to such beneficial interest and to have such debt securities registered in its name (if the debt securities are issuable as Registered Securities). Individual debt securities of such series so issued will be issued (a) as Registered Securities in denominations, unless otherwise specified by us, of $1,000 and integral multiples thereof if the debt securities are issuable as Registered Securities, (b) as Bearer Securities in the denomination or denominations specified by us if the debt securities are issuable as Bearer Securities or (c) as either Registered Securities or Bearer Securities as described above if the debt securities are issuable in either form. Limitations on Issuance of Bearer Securities The debt securities of a series may be issued as Registered Securities (which will be registered as to principal and interest in the register maintained by the registrar for such debt securities) or Bearer Securities (which will be transferable only by delivery). If such debt securities are issuable as Bearer Securities, the applicable prospectus supplement will describe certain special limitations and considerations that will apply to such debt securities. Certain Covenants Merger, Consolidation or Sale of Assets The indenture provides that we may not: (1) consolidate or merge with or into (whether or not we are the surviving corporation), or (2) sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of our properties or assets in one or more related transactions, to another corporation, Person or entity, unless: (a) either: (A) we are the surviving corporation, or (B) the entity or the Person (as defined) formed by or surviving any such consolidation or merger (if other than us) or to which the 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; (b) the entity or Person formed by or surviving any such consolidation or merger (if other than us) or the entity or Person to which the sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all our obligations under the debt securities and the indenture pursuant to a supplemental indenture in a form reasonably satisfactory to the trustee; (c) immediately after such transaction no Default (as defined) exists; and (d) except in the case of: (A) a merger of us with or into our Wholly Owned Restricted Subsidiary (as defined) and 9

(B) a merger entered into solely for the purpose of reincorporating us in another jurisdiction: (x) in the case of a merger or consolidation in which we are the surviving corporation, our Debt to Adjusted Consolidated Cash Flow Ratio (as defined) at the time of the transaction, after giving pro forma effect to the transaction as of such date for balance sheet purposes and as if the transaction had occurred at the beginning of our most recently ended four full fiscal quarter period for which internal financial statements are available for income statement purposes, would have been less than our Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such transaction, or (y) 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 us), or to which the sale, assignment, transfer, lease, conveyance or other disposition shall have been made, at the time of the transaction, after giving pro forma effect to the transaction as of such date for balance sheet purposes and 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 for income statement purposes, would have been less than our 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 entity or Person for purposes of this clause (y) the entity or Person will be substituted for us in the definition of Debt to Adjusted Consolidated Cash Flow Ratio and the defined terms included in the indenture. Subordination Debt securities of a series may be subordinated ("subordinated debt securities") to Senior Indebtedness (as defined in the applicable prospectus supplement) to the extent set forth in the prospectus supplement relating thereto. We conduct substantially all our operations through subsidiaries, and the holders of debt securities (whether or not subordinated debt securities) will be structurally subordinated to the creditors of our subsidiaries. Upon any payment or distribution of our assets to creditors or upon our total or partial liquidation or dissolution or in a bankruptcy, receivership, or similar proceeding relating to us or our property, holders of Senior Indebtedness shall be entitled to receive payment in full in cash of the Senior Indebtedness before holders of subordinated debt securities shall be entitled to receive any payment of principal, premium, or interest with respect to the subordinated debt securities, and until the Senior Indebtedness is paid in full, any distribution to which holders of subordinated debt securities would otherwise be entitled shall be made to the holders of Senior Indebtedness (except that such holders may receive shares of stock and any debt securities that are subordinated to Senior Indebtedness to at least the same extent as the subordinated debt securities). We may not make any payments of principal, premium, or interest with respect to subordinated debt securities, make any deposit for the purpose of defeasance of such subordinated debt securities, or repurchase, redeem, or otherwise retire (except, in the case of subordinated debt securities that provide for a mandatory sinking fund, by the delivery of subordinated debt securities by us to the trustee in satisfaction of our sinking fund obligation) any subordinated debt securities if (a) any principal, premium or interest with respect to Senior Indebtedness is not paid in full in cash within any applicable grace period (including at maturity) or (b) any other default on Senior Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms, unless, in either case, the default has been cured or waived and such acceleration has been rescinded, such Senior Indebtedness has been paid in full in cash or we and the trustee receive written notice approving such payment from the representatives of such Senior Indebtedness. During the continuance of any default (other than a default described in clause (a) or (b) above) with respect to any Designated Senior 10

Indebtedness (as defined in the applicable prospectus supplement) pursuant to which the maturity thereof may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, we may not pay the subordinated debt securities for a period (the "payment blockage period") commencing on the receipt by us and the trustee of written notice of such default from the representative of any Designated Senior Indebtedness specifying an election to effect a payment blockage period (a "blockage notice"). The payment blockage period may be terminated before its expiration by written notice to the trustee and us from the person who gave the blockage notice, by repayment in full in cash of the Senior Indebtedness with respect to which the blockage notice was given or because the default giving rise to the payment blockage period is no longer continuing. Unless the holders of such Designated Senior Indebtedness shall have accelerated the maturity thereof, we may resume payments on the subordinated debt securities after the expiration of the payment blockage period. Not more than one blockage notice may be given in any period of 360 consecutive days. In no event, however, may the total number of days during which any payment blockage period or periods is in effect exceed 179 days in the aggregate during any period of 360 consecutive days. After all Senior Indebtedness is paid in full and until the subordinated debt securities are paid in full, holders of the subordinated debt securities shall be subrogated to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness. By reason of such subordination, in the event of insolvency, creditors of ours who are holders of Senior Indebtedness, as well as certain general creditors of ours, may recover more, ratably, than the holders of the subordinated debt securities. Events of Default and Remedies The following events are defined in the indenture as "Events of Default" with respect to a series of debt securities: (a) default for 30 days in the payment when due of interest on the debt securities; (b) default in payment when due of the principal of or premium, if any, on the debt securities; (c) our failure or failure by any of our Subsidiaries (as defined) to comply with the provisions described under the caption "--Certain Covenants--Merger, Consolidation or Sale of Assets" or our failure to consummate a Change of Control Offer (as defined) or Asset Sale Offer (as defined) in accordance with the provisions of the indenture; (d) our failure or failure by any of our Subsidiaries for 30 days after notice to comply with any other agreements in the indenture or the debt securities; (e) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness (as defined) for money borrowed by us or any of our Significant Subsidiaries (as defined), or the payment of which is guaranteed by us or any of our Significant Subsidiaries, whether such Indebtedness or guarantee now exists, or is created after the date of the indenture, which default: (1) is caused by a failure to pay principal of or premium, if any, or interest on the Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of the default (a "Payment Default"); or (2) results in the acceleration of the 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; (f) failure by us or any of our 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 days; or 11

(g) certain events of bankruptcy or insolvency described in the indenture with respect to us or any of our Restricted Subsidiaries. (h) any other Event of Default provided with respect to debt securities of that series. An Event of Default with respect to one series of debt securities is not necessarily an Event of Default for another series. A prospectus supplement may omit, modify or add to the foregoing Events of Default. If any Event of Default occurs and is continuing, the trustee under the indenture or the holders of at least 25% in principal amount at maturity of the then outstanding notes of the applicable series may declare all the notes of such series 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 us, all outstanding debt securities will become due and payable without further action or notice. Holders of the debt securities may not enforce the indenture or the debt securities except as provided in the indenture. Subject to certain limitations, Holders of a majority in principal amount at maturity of the then outstanding debt securities may direct the trustee under the indenture in its exercise of any trust or power. The holders of a majority in aggregate principal amount at maturity of the debt securities then outstanding by notice to the trustee under the indenture may on behalf of the holders of all of such series of debt securities waive any existing Default or Event of Default and its consequences under the applicable indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of the debt securities. The indenture provides that if a Default occurs and is continuing and is known to the trustee, the trustee must mail to each holder of the relevant series of debt securities 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 debt security, the 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 debt securities. In addition, we are required to deliver to the 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. We are also required to deliver to the trustee, promptly after the occurrence thereof, written notice of any event that would constitute a Default, the status thereof and what action we are taking or proposes to take in respect thereof. Modification of the Indenture We and the trustee may enter into supplemental indentures without the consent of the holders of debt securities for one or more of the following purposes: (a) to evidence the succession of another person to us pursuant to the provisions of the indenture relating to consolidations, mergers and sales of assets and the assumption by such successor of our covenants, agreements and obligations in the indenture and in the debt securities; (b) to surrender any right or power conferred upon us by the indenture, to add to our covenants such further covenants, restrictions, conditions or provisions for the protection of the holders of all or any series of debt securities as our board of directors shall consider to be for the protection of the holders of such debt securities, and to make the occurrence, or the occurrence and continuance, of a default in any of such additional covenants, restrictions, conditions or provisions a default or an Event of Default under the indenture (provided, however, that with respect to any such additional covenant, restriction, condition or provision, such supplemental indenture may provide for a period of grace after default, which may be shorter or longer than that allowed in the case of other defaults, may provide for an immediate enforcement upon such default, may limit the remedies available to the trustee upon such default or may limit the right of holders of a majority in aggregate principal amount of any or all series of debt securities to waive such default); 12

(c) to cure any ambiguity or correct or supplement any provision contained in the indenture, in any supplemental indenture or in any debt securities that may be defective or inconsistent with any other provision contained therein, to convey, transfer, assign, mortgage or pledge any property to or with the trustee, or to make such other provisions in regard to matters or questions arising under the indenture as shall not adversely affect the interests of any holders of debt securities of any series; (d) to modify or amend the indenture in such a manner as to permit the qualification of the indenture or any supplemental indenture under the Trust Indenture Act as then in effect; (e) to add to or change any of the provisions of the indenture to provide that Bearer Securities may be registerable as to principal, to change or eliminate any restrictions on the payment of principal or premium with respect to Registered Securities or of principal, premium or interest with respect to Bearer Securities, or to permit Registered Securities to be exchanged for Bearer Securities, so as to not adversely affect the interests of the holders of debt securities or any coupons of any series in any material respect or permit or facilitate the issuance of debt securities of any series in uncertificated form; (f) to comply with the provisions of the indenture relating to consolidations, mergers and sales of assets; (g) in the case of subordinated debt securities, to make any change in the provisions of the indenture relating to subordination that would limit or terminate the benefits available to any holder of senior indebtedness under such provisions (but only if each such holder of senior indebtedness consents to such change); (h) to add guarantees with respect to the debt securities or to secure the debt securities; (i) to make any change that does not adversely affect the rights of any holder; (j) to add to, change, or eliminate any of the provisions of the indenture with respect to one or more series of debt securities, so long as any such addition, change or elimination not otherwise permitted under the indenture shall (1) neither apply to any debt security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor modify the rights of the holders of any such debt security with respect to such provision or (2) become effective only when there is no such debt security outstanding; (k) to evidence and provide for the acceptance of appointment by a successor or separate trustee with respect to the debt securities of one or more series and to add to or change any of the provisions of the indenture as shall be necessary to provide for or facilitate the administration of the indenture by more than one trustee; and (l) to establish the form or terms of debt securities and coupons of any series, as described under "Description of Debt Securities--General" above. With the consent of the holders of a majority in aggregate principal amount of the outstanding debt securities of each series affected thereby, we and the trustee may from time to time and at any time enter into a supplemental indenture for the purpose of adding any provisions to, changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental Indenture or modifying in any manner the rights of the holder of the debt securities of such series; provided, however, that without the consent of the holders of each debt security so affected, no such supplemental indenture shall (a) reduce the percentage in principal amount of debt securities of any series whose holders must consent to an amendment, (b) reduce the rate of or extend the time for payment of interest on any debt security or coupon or reduce the amount of any payment to be made with respect to any coupon, (c) reduce the principal of or extend the stated maturity of any debt security, (d) reduce the premium payable upon the redemption of any debt security or change the time at which any debt security may or shall be redeemed, (e) make any debt security payable in a currency other than that stated in the debt security, (f) in the case of any subordinated debt security or coupons appertaining thereto, make any change in the provisions of the indenture relating to subordination that adversely affects the rights of 13

any holder under such provisions, (g) release any security that may have been granted with respect to the debt securities, (h) make any change in the provisions of the indenture relating to waivers of defaults or amendments that require unanimous consent, (i) change any obligation of ours provided for in the indenture to pay additional interest with respect to Bearer Securities or (j) limit our obligation to maintain a paying agency outside the United States for payment on Bearer Securities or limit our obligation to redeem certain Bearer Securities. Satisfaction and Discharge of the Indenture; Defeasance The indenture shall generally cease to be of any further effect with respect to a series of debt securities if (a) we have delivered to the trustee for cancellation all debt securities of such series (with certain limited exceptions) or (b) all debt securities and coupons of such series not theretofore delivered to the trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year, and we shall have deposited with the trustee as trust funds the entire amount sufficient to pay at maturity or upon redemption all such debt securities and coupons (and if, in either case, we shall also pay or cause to be paid all other sums payable under the indenture by us). In addition, we shall have a "legal defeasance option" (pursuant to which we may terminate, with respect to the debt securities of a particular series, all of our obligations under such debt securities and the indenture with respect to such debt securities) and a "covenant defeasance option" (pursuant to which we may terminate, with respect to the debt securities of a particular series, our obligations with respect to such debt securities under certain specified covenants contained in the indenture). If we exercise our legal defeasance option with respect to a series of debt securities, payment of such debt securities may not be accelerated because of an Event of Default. If we exercise our covenant defeasance option with respect to a series of debt securities, payment of such debt securities may not be accelerated because of an Event of Default related to the specified covenants. The applicable prospectus supplement will describe the procedures we must follow in order to exercise our defeasance options. 14

DESCRIPTION OF CAPITAL STOCK Our authorized capital stock consists of 600,000,000 shares of common stock, par value $.01 per share, 90,000,000 shares of Class A common stock, par value $.01 per share, and 10,000,000 shares of preferred stock, par value $.01 per share. As of July 5, 2000 there were 183,683,790 shares of common stock outstanding, no shares of Class A common stock outstanding, 241,431 shares of 12 3/4% Senior Exchangeable Preferred Stock due 2010 outstanding and 200,000 shares of 8 1/4% Cumulative Convertible Redeemable Preferred Stock due 2012 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 Delaware General Corporation Law. Dividends and Liquidation Rights 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 for that purpose, subject to approval of certain holders of preferred stock. In the event of our dissolution, after satisfaction of amounts payable to our creditors and distribution of any preferential amounts to the holders of outstanding preferred stock, if any, 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 we 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 the election of directors. The holders of the shares of Class A common stock vote, except as provided under the Delaware General Corporation Law, together with the holders of the common stock and any other class or series of our stock accorded such general voting rights, as a single class. The holders of Class A common stock, subject to limitations, have a veto over certain significant corporate actions we may take. 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) of the transferor, such share of Class A common stock automatically converts, without any further action, into one share of common stock. However, a holder of shares of Class A common stock may pledge its shares to a lender under 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. 15

Dividends and Liquidation Rights Holders of shares of Class A common stock are entitled to the same dividends and liquidation rights as holders of shares of common stock. Preferred Stock Under our certificate of incorporation, we may issue up to 10,000,000 shares of preferred stock in one or more series. Our board of directors has the authority, without any vote or action by the stockholders, to create one or more series of preferred stock up to the limit of our authorized but unissued shares of preferred stock and to fix their designations, preferences, rights, qualifications, limitations and restrictions, 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. 12 3/4% Exchangeable Preferred Stock due 2010 Each share of exchangeable preferred stock has a liquidation preference of $1,000 per share and is exchangeable, at our option, in whole but not in part, for our exchange debentures. Voting Rights The shares of exchangeable preferred stock 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 certificate of designations, the holders of the exchangeable preferred stock will be entitled to elect two additional members to the board of directors. Dividends Dividends are paid on each March 15, June 15, September 15 and December 15, at an annual fixed rate of 12 3/4%. On or before December 15, 2003, we have the option to pay dividends in cash or in additional fully paid and non-assessable shares of exchangeable preferred stock having an aggregate liquidation preference equal to the amount of such dividends. After December 15, 2003, dividends will be paid only in cash. Mandatory Redemption We are required to redeem all of the shares of exchangeable preferred stock outstanding on December 15, 2010 at a redemption price equal to 100% of the liquidation preference of such shares, plus accumulated and unpaid dividends to the date of redemption. 16

Optional Redemption On or after December 15, 2003, we may redeem some or all of the shares of exchangeable preferred stock at any time at certain specified redemption prices. In addition, before December 15, 2001, we may redeem up to 35% of the exchangeable preferred stock with the proceeds of public equity offerings or strategic equity investments at a redemption price equal to 112.750% of the liquidation preference of the exchangeable preferred stock, together with accumulated and unpaid dividends. Change of Control If we experience specific kinds of changes in control, we will be required to make an offer to purchase any and all shares of exchangeable preferred stock at a purchase price of 101% of the liquidation preference of such shares together with all accumulated and unpaid dividends. Certain Covenants We issued the exchangeable preferred stock under a certificate of designations that became part of our certificate of incorporation. The certificate of designations contains certain covenants that, among other things, limit our ability and the ability of our subsidiaries to borrow money; pay dividends on stock or purchase capital stock; make investments and sell assets or merge with or into other companies. Ranking The exchangeable preferred stock ranks (1) senior to all our other classes of capital stock established after the issue date of the exchangeable preferred stock that do not expressly provide that they rank on par with the exchangeable preferred stock as to dividends and distributions upon our liquidation, winding up and dissolution and (2) on par with any class of capital stock established after the date of issuance of the exchangeable preferred stock the terms of which provide that such class or series will rank on par with the exchangeable preferred stock as to dividends and distributions upon our liquidation, winding up and dissolution. 8 1/4% Cumulative Convertible Redeemable Preferred Stock On November 19, 1999, we privately placed 200,000 shares of series A convertible preferred stock with a wholly owned subsidiary of GE Capital ("GE"). Each share of series A convertible preferred stock automatically converts into one share of series B convertible preferred stock upon a sale or other transfer of such share to a party other than an affiliate of GE. Each share of convertible preferred stock has a liquidation preference of $1,000 and is convertible, at the option of the holder, in whole or in part, into shares of our common stock. Voting Rights Holders of series A convertible preferred stock are entitled to vote on all matters voted on by holders of common stock, voting together as a single class with the other holders of common stock, on all matters submitted for a shareholder vote. Each share of series A convertible preferred stock has voting rights equal to the number of votes that could be cast by the holder of the number of shares of common stock into which each share of series A convertible preferred stock is convertible on the record date of such vote. The shares of series B convertible preferred stock have no voting rights, except as required by law and as specified in the certificate of designations if certain events occur or fail to occur. Convertibility The shares of convertible preferred stock are convertible, at the option of the holder, into shares of our common stock at a conversion price of $26.875 per share of common stock. 17

Dividends Dividends are paid on each March 15, June 15, September 15 and December 15, at an annual fixed rate of 8 1/4%. Dividends on the convertible preferred stock can be paid at our option in cash, common stock or any combination of cash and common stock. Holders of the 8 1/4% convertible preferred stock will also be eligible to receive additional dividends up to an amount of $1,000,000 per year, if certain events occur or fail to occur. Mandatory Redemption We are required to redeem all of the shares of convertible preferred stock outstanding on March 31, 2012 at a redemption price equal to 100% of the liquidation preference of such shares, plus accumulated and unpaid dividends to the date of redemption. Optional Redemption On or after October 1, 2002, we may redeem some or all of the shares of convertible preferred stock at any time at certain specified redemption prices. Change of Control Upon the occurrence of specified change of control events, the holders of the convertible preferred stock, if the current market price of our common stock as of the date of such change of control is less than the conversion price, have a one time option, exercisable at any time within ninety days following such change of control event, to convert all of their outstanding shares of convertible preferred stock into shares of our common stock at an adjusted conversion price per share equal to the greater of (1) the last reported sale price for one share of common stock in an arm's length transaction as of the date of such change of control and (2) $12.96. We may, at our option and in lieu of issuing the shares of common stock issuable upon a change of control event as described above, make a cash payment to holders of convertible preferred stock equal to the current market price of such common stock otherwise issuable. Certain Covenants We issued the exchangeable preferred stock under a certificate of designations that became part of our certificate of incorporation. The certificate of designations contains certain covenants that, among other things, limit our ability and the ability of our subsidiaries to pay dividends on stock or sell assets or merge with or into other companies. Ranking The convertible preferred stock, with respect to dividends and distributions upon our liquidation, dissolution or winding-up, ranks (1) senior to our common stock and all other classes of our capital stock authorized and issued after the issue date of the convertible preferred stock that do not expressly state that they rank on par with or senior to the convertible preferred stock with respect to dividends and distributions upon our liquidation, dissolution or winding-up, (2) on par with all other classes of our capital stock authorized and issued after the issue date of the convertible preferred stock that expressly provide that such class or series will rank on par with the convertible preferred stock with respect to dividends and distributions upon our liquidation, dissolution or winding-up, and (3) junior to (A) the senior exchangeable preferred stock, (B) up to an aggregate of $200.0 million in any class of capital stock authorized and issued after the issue date of the convertible preferred stock to replace the senior exchangeable preferred stock and (C) up to an aggregate of $400.0 million in any other class of senior stock authorized and issued after the issue date of the convertible preferred stock. 18

Senior Preferred Warrants In connection with the offering of a series of senior convertible preferred stock in August 1997 and October 1997, we issued warrants to purchase an aggregate of 1,314,990 shares of common stock, of which 835,990 remained outstanding as of May 1, 2000, at an exercise price of $7.50 per share. In connection with the offering of the cumulative convertible preferred stock in November 1999, we issued warrants to purchase an aggregate of 1,000,000 shares of our common stock at an exercise price of $26.875 per share. Certificate of Incorporation and By-laws Stockholders' rights and related matters are governed by the Delaware General Corporation Law, and our certificate of incorporation and the by-laws. Certain provisions of our 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 our 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. We believe that such provisions are necessary to enable us to develop our business in a manner that will foster our long-term growth without disruption caused by the threat of a takeover not deemed by our board of directors to be in our best interests and those of our stockholders. Classified Board of Directors and Related Provisions Our certificate of incorporation provides that our directors, 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 divided into three classes of directors, consisting of three, three and four directors. One class of directors, initially consisting of four directors, was elected for a term expiring at the annual meeting of stockholders to be held in 2001, another class initially consisting of four directors was elected for a term expiring at the annual meeting of stockholders in 2002, and another class initially consisting of three directors was elected for a term expiring at the annual meeting of stockholders in 2003. The classified board provisions will prevent a party who acquires control of a majority of our outstanding voting stock from obtaining control of our board of directors until the second annual stockholders meeting following the date such party obtains the controlling interest. Voting stock is defined in our certificate of incorporation as the outstanding shares of our capital stock entitled to vote in a general vote of our stockholders as a single class with shares of common stock, which shares of capital stock include the shares of Class A common stock and shares of our 8 1/4% cumulative convertible redeemable preferred stock. No Stockholder Action by Written Consent; Special Meeting The certificate of incorporation prohibits stockholders from taking action by written consent in lieu of an annual or special meeting, except relating to holders of Class A common stock on matters on which they are entitled to vote and, thus, stockholders may only take action at an annual or special meeting called in accordance with our by-laws. The by-laws provide that special meetings of stockholders may only be called by our secretary at the direction of our board of directors under 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 our capital stock entitled to vote from unilaterally using the written consent procedure to take stockholder action. Advance Notice Requirements for Stockholder Proposals and Director Nominations Our by-laws establish advance notice procedures for 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 19

meeting must be in writing and received by our secretary at least 90 days but not more than 120 days prior to the first anniversary of our preceding year's annual meeting. However, if the date of our annual meeting is more than 30 days earlier than, or more than 90 days later than, the anniversary date of our preceding year's annual meeting, notice by a stockholder will be considered timely if it is delivered not earlier than the 120th day prior to such annual meeting and not later than 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 concerning the stockholder giving the notice and each nominee. By requiring advance notice of nominations by stockholders, these procedures will afford our board of directors an opportunity to consider the qualifications of the proposed nominees and, to the extent deemed necessary or desirable by the board of directors, to inform stockholders about these qualifications. By requiring advance notice of other proposed business, these procedures will provide our board of directors with an opportunity to inform stockholders of any business proposed to be conducted at a meeting, together with any recommendations as to the board of directors' position on action to be taken on such business. This should allow stockholders to better decide whether to attend a meeting or to grant a proxy for the disposition of any such business. Dilution Our certificate of incorporation provides that our 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 us shares of stock or other securities of us or of any other corporation. Our board of directors is authorized to issue these rights even though the creation and issuance of these rights could have the effect of discouraging third parties from seeking, or impairing their right to seek, to: (1) acquire a significant portion of our outstanding securities; (2) engage in any transaction which might result in a change of control of the corporation; or (3) enter into any agreement, arrangement or understanding with another party to accomplish these transactions or for the purpose of acquiring, holding, voting or disposing of any of our securities. Amendments Our certificate of incorporation and by-laws provide that we may amend, alter, change or repeal any provision contained in our certificate of incorporation or a preferred stock designation. 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 our certificate of incorporation, including the provisions discussed above relating to the classification of our board of directors, prohibiting stockholder action by written consent, and prohibiting the calling of special meetings by stockholders. Our 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; but the board may alter, amend or repeal or adopt new by-laws in conflict with some of these provisions by a two-thirds vote of the entire board. Rights Plan Rights Our board of directors has declared a dividend of one right for each outstanding share of common stock and each outstanding share of Class A common stock. Rights have been issued in connection with each outstanding share of common stock and Class A common stock; and rights will be issued in connection with 20

common stock and Class A common stock issued subsequently until the distribution date, and, in certain circumstances, for common stock and Class A common stock issued after the distribution date referred to below. Each right, when it becomes exercisable as described below, will entitle the registered holder to purchase from us one one-thousandth of a share of Series A Participating Cumulative Preferred Stock at a price of $110.00 per one one- thousandth of a share, subject to adjustment in certain circumstances. The description and terms of the rights are set forth in a rights agreement between us 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, unless earlier redeemed by us. Until a right is exercised, the holder, as such, will have no rights as our stockholder, including the right to vote or to receive dividends. Distribution Date Under the rights agreement, the "distribution date" is the earlier of: (1) such time as we learn 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 our outstanding voting securities (such person or group being an "acquiring person"), subject to the exceptions relating to Bell South, Bell Atlantic, GTE and Berkshire Fund IV Investment Corp., Berkshire Investors LLC and Berkshire Partners LLC (collectively, the "Berkshire group"), unless provisions preventing accidental triggering of the distribution of the rights apply, and (2) the close of business on such date, if any, as may be designated by our 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 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 When 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 one-thousandths 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. If we are 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 if 50% or more of our assets or assets representing 50% or more of our revenues or cash flow are sold, leased, exchanged or otherwise transferred to 21

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, 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 some cases, book value of twice the purchase price. If we are 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 if 50% or more of our assets or assets representing 50% or more of our revenues or cash flow are sold, leased, exchanged or otherwise transferred 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 to purchase for the purchase price, at such holder's option: (1) that number of shares of the surviving corporation, which could be us, in the transaction with such entity, which at the time of the transaction would have a book value of twice the purchase price, (2) 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 (3) if such entity has an affiliate which has publicly traded common shares, that number of common shares of such affiliate which at the time of the transaction would have a 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 will be unable to exercise or transfer any such right. Redemption At any time prior to the earlier of (1) such time as a person or group becomes an acquiring person and (2) the expiration date, our 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 ours deemed by our 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. Immediately upon the action of our 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, our 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 under the terms of the rights agreement. Amendment At any time prior to the distribution date, we may, without the approval of any holder of any rights, supplement or amend any provision of the rights agreement, including 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 under certain adjustments therein. Certain Effects of the Rights Plan The rights plan is designed to protect our stockholders in the event of unsolicited offers to acquire us and other coercive takeover tactics which, in the opinion of our board of directors, could impair its ability to represent stockholder interests. The provisions of the rights plan may render an unsolicited takeover of us more difficult or less likely to occur or might prevent such a takeover, even though such takeover may offer our stockholders the opportunity to sell their stock at a price above the prevailing market rate and may be favored by a majority of our stockholders. 22

Section 203 of the Delaware General Corporation Law Section 203 of the Delaware General Corporation Law 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 between an interested stockholder and a corporation for a period of three years after the date the interested stockholder acquired its stock, unless: (1) the business combination is approved by the corporation's board of directors prior to the date the interested stockholder acquired shares; (2) 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 (3) 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 business combination is 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. A Delaware corporation, under a provision in its certificate of incorporation or by-laws, may elect not to be governed by Section 203 of the Delaware General Corporation Law. We are subject to the restrictions imposed by Section 203. Under certain circumstances, Section 203 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. It is anticipated that the provisions of Section 203 of the Delaware General Corporation Law may encourage companies interested in acquiring us 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 Our certificate of incorporation provides that none of our directors will be personally liable to us or our 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 us or our 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 Delaware General Corporation Law, or (4) for any transaction from which the director derived an improper personal benefit. The effect of these provisions will be to eliminate our rights and the rights of our stockholders (through stockholders' derivatives suits on behalf of us) 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.

PLAN OF DISTRIBUTION The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices (which may be changed from time to time), at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. Each prospectus supplement will describe the method of distribution of the securities offered therein. Our company and any selling stockholders may sell securities directly, through agents designated from time to time, through underwriting syndicates led by one or more managing underwriters or through one or more underwriters acting alone. The selling stockholders may also distribute securities through one or more special purpose trusts, which will enter into forward purchase arrangements with selling stockholders and distribute their own securities. Each prospectus supplement will describe the terms of the securities to which such prospectus supplement relates, the names of the selling stockholders and the number of shares of common stock to be sold by each, the name or names of any underwriters or agents with whom we or the selling stockholders, or both, have entered into arrangements with respect to the sale of such securities, the public offering or purchase price of such securities and the net proceeds we or the selling stockholders will receive from such sale. In addition, each prospectus supplement will describe any underwriting discounts and other items constituting underwriters' compensation, any discounts and commissions allowed or paid to dealers, if any, any commissions allowed or paid to agents, and the securities exchange or exchanges, if any, on which such securities will be listed. Dealer trading may take place in certain of the securities, including securities not listed on any securities exchange. If so indicated in the applicable prospectus supplement, we or the selling stockholders, or both, will authorize underwriters or agents to solicit offers by certain institutions to purchase securities from us or the selling stockholders, or both, pursuant to delayed delivery contracts providing for payment and delivery at a future date. Institutions with which such contracts may be made include, among others: --commercial and savings banks; --insurance companies; --pension funds; --investment companies; --educational and charitable institutions. In all cases, such institutions must be approved by us or the selling stockholders, or both. Unless otherwise set forth in the applicable prospectus supplement, the obligations of any purchaser under any such contract will not be subject to any conditions except that (i) the purchase of the securities will not at the time of delivery be prohibited under the laws of the jurisdiction to which such purchaser is subject and (ii) if the securities are also being sold to underwriters acting as principals for their own account, the underwriters will have purchased such securities not sold for delayed delivery. The underwriters and such other persons will not have any responsibility in respect of the validity or performance of such contracts. Any selling stockholder, underwriter or agent participating in the distribution of the securities may be deemed to be an underwriter, as that term is defined in the Securities Act, of the securities so offered and sold and any discounts or commissions received by them, and any profit realized by them on the same or resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. Certain of any such underwriters and agents, including their associates, may be customers of, engage in transactions with and perform services for us and our subsidiaries in the ordinary course of business. One or more of our affiliates may from time to time act as an agent or underwriter in connection with the sale of the securities to the extent permitted by applicable law. The participation of any such affiliate in the offer and sale of the securities will comply with Rule 2720 of the Conduct Rules of the National Association of Securities Dealers, Inc. regarding the offer and sale of securities of an affiliate. 26

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 attorneys' 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 which 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 indemnity for such expenses as such court shall deem proper. Accordingly, the Restated Certificate of Incorporation of the Company (Exhibit 3.1) provides 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 Company, directors, officers, employees or agents of a subsidiary, and 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 Company, with the same scope and effect as the indemnification of directors and officers of the Company. However, 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. II-1

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 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 17. Undertakings The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) under the Securities Act of 1933 if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act, 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. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) That, for the purpose of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act (and, where applicable, each filing of any employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act) that is incorporated by reference in the Registration Statement 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. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in Item 15 (other than the provisions relating to insurance), or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy expressed in the Securities Act 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 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 and will be governed by the final adjudication of such issue.
