("CCA"), a wholly owned subsidiary of the Corporation, and shared investment power with CCA over an aggregate of 15,597,783 shares of Common Stock of the Corporation (the "Contributed Shares"), when the Contributed Shares were contributed by CCA to Crown Atlantic Holding Company LLC, a Delaware limited liability company ("HoldCo"), pursuant to the terms of the Operating Agreement of HoldCo entered into as of March 31, 1999 by BAM and CCA (the "HoldCo Operating Agreement"). BAM's actual economic interest in the Contributed Shares is determined under the terms of the HoldCo Operating Agreement. A copy of the HoldCo Operating Agreement is filed as Exhibit 3 hereto and incorporated herein by reference. The HoldCo Operating Agreement was entered into in connection with the closing of the transactions contemplated by the Formation Agreement dated as of December 8, 1998, by and among BAM, CCA, the Corporation and certain transferring partnerships. The Formation Agreement and Amendment Number 1 to such Formation Agreement, are filed as Exhibit 1 and Exhibit 2 hereto, respectively, and are referred to herein collectively as the "Formation Agreement." Pursuant to the terms of the Formation Agreement, BAM and CCA formed a joint venture consisting of three limited liability companies (including HoldCo) to own and operate a significant portion of BAM's wireless communications towers. BAM and other transferring partnerships contributed certain of their respective wireless communications towers and other related assets (the "BAM Contributed Assets") to Crown Atlantic Company LLC, the operating subsidiary of the joint venture and CCA contributed the Contributed Shares and $200,000,000 in cash to HoldCo. Item 4. Purpose of Transaction. BAM acquired shared voting and investment power over the Contributed Shares on March 31, 1999, when CCA contributed the Contributed Shares to HoldCo in connection with the formation of the joint venture contemplated by the Formation Agreement. Pursuant to the terms of the HoldCo Operating Agreement, the exercise of any voting rights with respect to the Contributed Shares requires the mutual consent of BAM and CCA, and, therefore, BAM shares voting power over the Contributed Shares with CCA. In the absence of the mutual consent of BAM and CCA as to the exercise of voting rights, the HoldCo Operating Agreement provides that the Contributed Shares will be voted on each matter submitted to a vote of the stockholders of the Corporation for and against such

Cusip No. 228227104 Page 6 of 7 matter in the same proportion as the vote of all other shares entitled to vote on such matter are voted for and against such matter. Pursuant to the terms of the HoldCo Operating Agreement, (i) at any time after March 31, 2002, BAM may unilaterally elect to dissolve HoldCo by giving written notice of such election to CCA and (ii) at any time after March 31, 2003, CCA may unilaterally elect to dissolve HoldCo by giving written notice of such election to BAM. In the event of such election by BAM or CCA, the Contributed Shares, including all dividends payable in stock and distributions payable with respect to the Contributed Shares will be distributed to BAM, subject to the limitations set forth in Section 9.5 (a) (2) of the HoldCo Operating Agreement. BAM does not presently intend to elect the dissolution of HoldCo. Other than as disclosed in this Statement and except for enforcement by BAM of its rights under the HoldCo Operating Agreement and the Formation Agreement, none of BAM, Bell Atlantic Mobile, Inc., Bell Atlantic Cellular Holdings, L.P., NYNEX PCS Inc. or BAC, and to the best knowledge of each of them, none of the persons named in Schedules I, II and III hereto, presently has any plan or proposal which relate to, or might result in, any of the events described in paragraphs (a) through (j), inclusive, of Item 4 of Schedule 13D. Item 5. Interest in Securities of the Issuer. BAM is the beneficial owner of 15,597,783 shares of Common Stock of the Corporation. BAM has, together with CCA Investment Corp., shared voting power with respect to 15,597,783 shares of Common Stock, which constitutes approximately 16.4% of the Common Stock of the Corporation outstanding on March 15, 1999, and shared dispositive power with respect to 15,597,783 shares of Common Stock. BAM and BAC disclaim beneficial ownership of the Contributed Shares for all purposes other than Section 13 of the Securities Exchange Act of 1934, as amended. None of Bell Atlantic Mobile, Inc., Bell Atlantic Cellular Holdings, L.P., NYNEX PCS Inc. or BAC beneficially own any shares of Common Stock. Item 6. Contract, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer. Formation Agreement BAM, CCA and certain other parties entered into the Formation Agreement on December 8, 1998, and amended the Formation Agreement with Amendment Number 1 dated March 31, 1999. The following description of certain provisions of the Formation Agreement is only a summary and does not purport to be complete. This description is qualified in its entirety by reference to (i) the complete text of the Formation Agreement, a copy of which is attached hereto as Exhibit 1 and (ii) the complete text of Amendment Number 1, a copy of which is attached hereto as Exhibit 2. Pursuant to the terms of the Formation Agreement, the parties agreed to create a joint venture to own and manage a significant portion of BAM's wireless communications towers. BAM and certain transferring partnerships agreed to transfer the BAM Contributed Assets and the BAM Assumed Liabilities (as both terms are defined in the Formation Agreement) to Crown Atlantic Company LLC ("OpCo") in exchange for a membership interest in OpCo, and CCA agreed to transfer $50,000,000 in cash to OpCo in exchange for a membership interest in OpCo. BAM and CCA agreed to then transfer their respective interests in OpCo (other than a .001 interest to be retained by BAM) to Crown Atlantic Holding Sub LLC ("HoldCo Sub") in exchange for membership interests in HoldCo Sub. BAM and CCA agreed to then contribute to HoldCo their respective interests in HoldCo Sub, and CCA

Cusip No. 228227104 Page 7 of 7 also agreed to contribute $200,000,000 in cash and the Contributed Shares to HoldCo, in exchange for membership interests in HoldCo. The closing of the transactions contemplated by the Formation Agreement took place on March 31, 1999.

The following description of certain provisions of the HoldCo Operating Agreement is only a summary and does not purport to be complete.

Pursuant to the terms of the HoldCo Operating Agreement, in exchange for membership interests in HoldCo, each of BAM and CCA contributed its respective interest in HoldCo Sub to HoldCo, and CCA contributed $200,000,000 in cash and the Contributed Shares to HoldCo. At the closing of the transactions contemplated by the Formation Agreement, CCA received a 61.47% interest in HoldCo and BAM received a 38.53% interest in HoldCo. Under the HoldCo Operating Agreement, BAM and CCA share voting power over the Contributed Shares, and pursuant to the terms of the HoldCo Operating Agreement, the exercise of any voting rights with respect to the Contributed Shares requires the mutual consent of BAM and CCA. In the absence of the mutual consent of BAM and CCA as to the exercise of voting rights, the HoldCo Operating Agreement provides that the Contributed Shares will be voted on each matter submitted to a vote of the stockholders of THE CORPORATION for and against such matter in the same proportion as the vote of all other shares entitled to vote on such matter are voted for and against such matter. Additionally, pursuant to the terms of the HoldCo Operating Agreement, (i) at any time after March 31, 2002, BAM may unilaterally elect to dissolve HoldCo by giving written notice of such election to CCA and (ii) at any time after March 31, 2003, CCA may unilaterally elect to dissolve HoldCo by giving written notice of such election to BAM. In the event of such election by either BAM or CCA, the Contributed Shares, including all dividends and distributions payable with respect to the Contributed Shares will be distributed to BAM, subject to the limitations set forth in Section 9.5 (a) (2) of the HoldCo Operating Agreement.

To the extent that any such required consent to the assignment of any such Contract or asset is not obtained, BAM will

subcontract to OpCo the performance of all obligations and the right to receive all benefits thereunder. To the extent the consent of the counterparty to such subcontracting is required under the terms of any such Contract or asset, BAM will use commercially reasonable efforts to obtain such consent; and BAM will not subcontract as described in the immediately preceding sentence in those cases, if any, in which subcontracting is expressly prohibited.

Consent of Third Parties. Nothing in this Agreement shall be construed as an attempt by BAM to assign to OpCo pursuant to this Agreement any Contract, Governmental Permit, franchise, claim or asset included in the BAM Contributed Assets that is by its terms or by Law nonassignable without the consent of any other party or parties, unless such consent or approval shall have been given, or as to which all the remedies for the enforcement thereof available to BAM would not by Law pass to OpCo as an incident of the assignments provided for by this Agreement (a "Non- Assignable Contract"). To the extent that any consent in respect of, or a novation of, a Non-Assignable Contract has not been obtained, BAM shall continue to use commercially reasonable efforts to obtain any such consent or novation until such time as it shall have been obtained, and BAM shall use commercially reasonable efforts to cooperate with OpCo to provide that OpCo shall receive the interest of BAM in the benefits under such Non-Assignable Contract, including performance by BAM as agent if commercially reasonable, provided that OpCo shall undertake to pay or satisfy the corresponding Liabilities under the terms of such Non-Assignable Contract to the extent that OpCo would have been responsible therefor if such consent or approval had been obtained. If, despite such efforts, BAM is unable to provide OpCo with the interest of BAM in the benefits under any such Non-Assignable Contract, such Non-Assignable Contract shall not be included in the BAM Contributed Assets, and the Liabilities under such Non-Assignable Contract shall not be included in the BAM Assumed Liabilities, in each case until such time as BAM is able to provide OpCo with the interest of BAM in such benefits or BAM obtains the aforesaid consent or novation with respect to the Non-Assignable Contract.

Notwithstanding any provision to the contrary in this Section 2.3 or elsewhere in this Agreement, at the Closing the following items shall be apportioned between BAM and the Transferring Partnerships, on the one hand, and OpCo, on the other hand, with such adjustments to be made as of the Closing Date by the party that on a net basis owes money to the other party under this Section 2.3.8 by wire transfer of immediately available funds to such accounts as such other party shall specify in writing: (a) rents and revenues under all Contracts included in the BAM Contributed Assets; (b) Prepaid Expenses; (c) federal, state, local or foreign Taxes (other than income taxes) payable with respect to the BAM Contributed Assets; and (d) charges and payments under all Contracts included in

the BAM Contributed Assets. Such apportionments shall be made pro rata on a per diem basis as of the Closing Date so that all such rents, revenues, Taxes, charges and payments attributable to the period prior to the Closing Date are for the account of BAM; and all such rents, revenues, Taxes, charges and payments attributable to the period from and after the Closing Date are for the account of OpCo. If any of the aforesaid apportionments cannot be calculated accurately on the Closing Date, then the same shall be calculated and adjusted once by BAM and OpCo after the Closing Date in accordance with the following procedures. Within five business days after the last day of the third full calendar month following the Closing Date, BAM and OpCo shall exchange their respective post-Closing calculations of such apportionments. BAM and OpCo shall in good faith agree upon the post-Closing apportionments on or before the last day of the fourth full calendar month following the Closing Date. If at the end of such period, BAM and OpCo cannot agree on the post-Closing apportionments, BAM and OpCo shall submit to an independent accounting firm (the "Accounting Firm") for review and resolution any and all matters which remain in dispute. The Accounting Firm shall be Arthur Anderson, LLP or, if such firm is unable or unwilling to act, such other nationally recognized independent public accounting firm as shall be agreed upon by BAM and OpCo in writing. The Accounting Firm shall be instructed to, within thirty (30) days after the submission of any disputed matters, review and resolve all such disputed matters and to report its resolution thereof to BAM and OpCo, and such report shall be final, binding and conclusive on BAM and OpCo with respect to all such disputed matters. The fees and expenses of the Accounting Firm incurred pursuant to this Section 2.3.8 shall be borne fifty percent (50%) by BAM and fifty percent (50%) by OpCo. No other post-Closing apportionments shall be made by the parties. Either party owing the other party a sum of money based on the agreed-upon post-Closing apportionments shall pay said sum to the other party on or before the last day of the fifth full calendar month following the Closing Date. If payment of any such amount is not paid when due, interest shall accrue on the past due amount at a rate equal to the Prime Rate plus two percent (2%) per annum from the due date to the date of payment. The aforesaid post-Closing adjustment shall be the only post-Closing adjustment of the items to be apportioned under this Section 2.3.8. The provisions of this Section 2.3 shall not affect the obligations of BAM and OpCo under this Agreement with respect to the BAM Retained Liabilities and the BAM Assumed Liabilities, respectively.

(a) As used in this Agreement, the term "Included Tower Structures" shall mean all Tower Structures constructed as of the Closing Date and granted, contributed, conveyed, assigned, transferred

and delivered by BAM and the Transferring Partnerships to OpCo at the Closing, and all Tower Structures that meet any of the following criteria (which for purposes of this Section 3.8 shall be deemed to have been granted, contributed, conveyed, assigned, transferred and delivered by BAM and the Transferring Partnerships to OpCo at the Closing): (i) any Tower Structure that is planned, but not yet constructed, and for which a Tower Site has been secured and all Governmental Permits that are required for the construction thereof have been secured, (ii) any Tower Structure for which BAM has not secured a required consent or approval to the assignment of the related Site Lease to OpCo at the Closing, but for which BAM or a Transferring Partnership is nonetheless able to deliver to OpCo, from and after the Closing, the interest of BAM or the applicable Transferring Partnership in the economic benefits of the Tower Structure, and (iii) any Tower Structure located on a Tower Site that is the subject of an Environmental Condition that is being remediated by BAM pursuant to the provisions of Section 6.1.7 and for which BAM or a Transferring Partnership delivers to OpCo, from and after the Closing, the interest of BAM or the applicable Transferring Partnership in the economic benefits of the Tower Structure. (b) Notwithstanding any other provision of this Agreement to the contrary, if the number of Included Tower Structures exceeds 1,427, the consideration to be paid, distributed and issued to BAM and the Transferring Partnerships under this Agreement shall be increased by an amount (the "Additional Consideration") equal to the product determined by multiplying (i) $320,000 by (ii) the number of Included Tower Structures in excess of 1,427. Such Additional Consideration shall be provided by increasing the BAM HoldCo Interest provided, however, that such adjusted interest must be less than 50%. If the amount of the Additional Consideration is such that the BAM HoldCo Interest, as adjusted pursuant to this Section 3.8(b), would be greater than or equal to 50%, the BAM HoldCo Interest shall be adjusted to 49.9% and Bidder and BAM shall agree upon the form of additional consideration to be provided by Bidder, which may include an increase of the Bidder Contributed Cash and an increase in the number of Bidder Contributed Shares. The increased BAM HoldCo Interest shall be equal to the quotient of (A) an amount equal to (1) $650,000,000 plus (2) the Additional Consideration less (3) the amount of the BAM Capital Distribution, divided by (B) an amount equal to (1) $650,000,000 plus (2) the Additional Consideration, plus (3) $250,000,000, being the amount of the Bidder Contributed Cash, plus (4)

$197,000,000, less (5) the amount of the BAM Capital Distribution. (c) Notwithstanding any other provision of this Agreement to the contrary, if the number of Included Tower Structures is less than 1,427, the consideration to be paid, distributed and issued to BAM and the Transferring Partnerships under this Agreement shall be decreased by an amount (the "Amount of Decrease in Consideration") equal to the product determined by multiplying (i) $320,000 by (ii) the difference between 1,427 and the number of Included Tower Structures. Such decrease in consideration shall be provided in accordance with the following: (i) If as a result of the number of Included Tower Structures being less than 1,427, the Lender reduces the amount of the Closing Financing Amount, then the amount of the Financing Distribution shall be reduced by an amount equal to the amount by which the Closing Financing Amount was reduced; and (ii) The number of Bidder Contributed Shares shall be decreased from 15,597,783 shares of Bidder Common Stock to such number of shares of Bidder Common Stock that is equal to the quotient of (A) the Adjusted Aggregate Share Value, divided by (B) $12.63 per share. As used herein, the term "Adjusted Aggregate Share Value" means the lesser of : (x) the quotient of (1) the difference between (aa) the product determined by multiplying (i) 90% by (ii) an amount equal to $650,000,000 less the Amount of Decrease in Consideration, less the amount of the BAM Capital Distribution, and (bb) the product determined by multiplying 10% by $250,000,000, being the amount of the Bidder Contributed Cash, divided by (2) 110%; or (y) the difference between (1) the product determined by multiplying (aa) 90% by (bb) an amount equal to $650,000,000 less the Amount of Decrease in Consideration, and (2) the amount of the BAM Capital Distribution; and

(iii) The BAM HoldCo Interest shall be decreased from a 37.7 Percentage Interest to such lower Percentage Interest that is equal to the quotient of (A) the difference between (1) $650,000,000 less the Amount of Decrease in Consideration and (2) the amount of the BAM Capital Distribution, divided by (B) an amount equal to (1) $650,000,000 less the Amount of Decrease in Consideration, plus (2) $250,000,000, being the amount of the Bidder Contributed Cash, plus (3) the Adjusted Aggregate Share Value, less (4) the amount of the BAM Capital Distribution. Exhibit AA contains six examples of the above calculations applicable to this Section 3.8(c), as well as two expanded calculations. (d) If any Tower Structure does not qualify as an Included Tower Structure at Closing because at the Closing BAM or a Transferring Partnership is unable to deliver to OpCo the interest of BAM or the applicable Transferring Partnership in the economic benefits of a Tower Structure (i) for which BAM has not secured a required consent or approval to the assignment of the related Site Lease to OpCo, or (ii) which is located on a Tower Site that is the subject of an Environmental Condition that is being remediated by BAM pursuant to the provisions of Section 6.1.7, and, as a result, the consideration paid, distributed and issued to BAM and the Transferring Partnerships at the Closing is decreased pursuant to Section 3.8(c), and if BAM or the applicable Transferring Partnership is subsequently able to deliver to OpCo the interest of BAM or the applicable Transferring Partnership in the economic benefits of the Tower Structure, then, effective as of the date that such economic benefits begin to be delivered to OpCo, the decrease in consideration that was made pursuant to Section 3.8(c) with respect to the Tower Structure shall be reversed and shall be recalculated, counting the Tower Structure as an Included Tower Structure. Adjustments Based Upon Revenue Run Rate of Included Towers. (a) For purposes of this Section 3.9, the average annual aggregate rents receivable from third party tenants for each Tower Structure shall be $11,186 per year (determined by dividing (i) $15,962,000 by (ii) 1,427 Tower Structures). (b) At the Closing, the annualized aggregate rents receivable from third party tenants for the Included Tower Structures (the "Actual Third Party Rents for the Included Towers") shall be determined by the parties and then compared with the product determined by multiplying (i) the number of Included Tower Structures by (ii) $11,186 (the "Target Third Party Rents for the Included Towers").

(c) If at the Closing the Actual Third Party Rents for the Included Towers equal or exceed the Target Third Party Rents for the Included Towers, there shall be no amounts owing by BAM to OpCo, or by OpCo to BAM, on account of the amount of rents receivable from third party tenants for the Included Tower Structures. (d) If at the Closing the Actual Third Party Rents for the Included Towers are less than the Target Third Party Rents for the Included Towers, then the following provisions of this subsection (d) shall apply from and after the Closing Date until such time that the Actual Third Party Rents for the Included Towers equal or exceed the Target Third Party Rents for the Included Towers. On the first day of each calendar month, OpCo shall calculate the difference between the Actual Third Party Rents for the

Included Towers (expressed in a monthly amount, determined by dividing the annual rents for each Included Tower Structure by 12) and the Target Third Party Rents for the Included Towers (expressed in a monthly amount, determined by multiplying (A) $932.17 by (B) the number of Included Tower Structures) as of such date. On or before the tenth day of such month, OpCo shall deliver to BAM an invoice for the difference so calculated (the "Monthly Third Party Rent Shortfall"), which shall be accompanied by reasonable evidence supporting OpCo's calculation of the Monthly Third Party Rent Shortfall. BAM shall pay each such invoice within 30 days after BAM's receipt of the invoice.

(e) Amounts payable by BAM under Section 3.10 below shall be counted as rents receivable from third party tenants for the Included Tower Structures for purposes of determining the Actual Third Party Rents for the Included Towers under this Section 3.9. Adjustment Based Upon Revenues Receivable under Certain Third Party Leases. Set forth on Schedule 3.10 is a description of certain third party leases covering the Tower Structures which were entered into by BAM or a Transferring Partnership (as lessor) pursuant to a swap or other arrangement (collectively, the "Swap Lease Agreements," and each, individually, a "Swap Lease Agreement"). With respect to each Swap Lease Agreement covering any of the Included Tower Structures, on or before the tenth day of each calendar month from and after the Closing Date until the time specified in the following sentence, BAM or the applicable Transferring Partnership shall pay to OpCo an amount equal to the difference, if any, between (a) the monthly rent that OpCo would have received under the Swap Lease Agreement if the rents payable by the third party lessee thereunder were set at the rental rates payable to OpCo under the Global Lease Agreement, and (b) the monthly rent receivable by OpCo under the Swap Lease Agreement. The payment obligation of BAM or the applicable Transferring Partnership under the preceding sentence with respect to a particular Swap Lease Agreement shall terminate on the date that the third party lessee no longer has lease rights under the Swap Lease Agreement with respect to the subject Included Tower Structure. ARTICLE 4. CLOSING Closing. The closing (the "Closing") of the transactions contemplated by this Agreement shall take place at 10:00 A.M., local time, on March 31, 1999, or, if later, the first business day following the satisfaction or waiver of the conditions precedent set forth in Article 4 hereof. The Closing shall take place at the offices of Morgan, Lewis & Bockius LLP, 1701 Market Street, Philadelphia, Pennsylvania 19103 or at such other location as the parties shall agree.

Except as disclosed to OpCo in the Schedules to this Agreement (with each disclosure made in the Schedule in response to any Section of these representations and warranties being deemed to be disclosed in response to, and to qualify, each other Section of these representations and warranties), BAM hereby represents and warrants to OpCo as follows: Corporate. BAM is a general partnership, duly organized and validly existing under the laws of the State of Delaware. BAM is qualified to do business in any jurisdiction where the ownership, use or occupancy of the BAM Contributed Assets would require it to be so qualified, except where the failure so to qualify would not have a BAM Material Adverse Effect. BAM has the requisite corporate power and authority to own, lease, use and occupy the BAM Contributed Assets as they are now being owned, leased, used and occupied. Authorization. BAM has the requisite corporate power and authority to execute and deliver the Transaction Documents to which it is a party and to perform the transactions performed or to be performed by it thereunder. Such execution, delivery and performance by BAM have been duly authorized by all necessary corporate action. Each Transaction Document executed and delivered by BAM has been duly executed and delivered by BAM and constitutes a valid and binding obligation of BAM, enforceable against BAM in accordance with its terms. Consents and Approvals. Except for compliance with (w) the HSR Act, (x) to the extent required, notice to and the consent and approval of the Connecticut Department of Environmental Protection ("CTDEP") under the Connecticut Transfer Act ("CTA"), (y) to the extent required, notice to and the consent and approval of the New Jersey Department of Environmental Protection ("NJDEP") under the Industrial Site Recovery Act

("ISRA") and (z) the consents specified in Schedule 5.1.3, neither the execution and delivery by BAM of the Transaction Documents to which it is a party, nor the performance of the Transactions performed or to be performed by BAM, will (i) require any filing, consent or approval or constitute a Default under (A) any Law or Court Order to which BAM or any of the BAM Contributed Assets is subject, (B) the Charter Documents or bylaws of BAM or (C) any Contract, Governmental Permit or other document to which BAM is a party or by which any of the BAM Contributed Assets is bound, except with respect to clauses (A) and (C), such Defaults that, individually or in the aggregate, would not have a BAM Material Adverse Effect, or (ii) result in the creation or imposition of any Encumbrance upon any of the BAM Contributed Assets, other than Permitted Encumbrances. Title to and Condition of Assets and Related Matters. To BAM's knowledge, BAM owns and will transfer to OpCo at the Closing good and marketable title to, or, with respect to leased assets, a valid leasehold interest in, all of the BAM Contributed Assets, free from any Encumbrances except Permitted Encumbrances. To BAM's knowledge, the use of the BAM Contributed Assets is not subject to any Encumbrances, other than Permitted Encumbrances, and such use does not materially encroach on the property or rights of any other Person. All of the BAM Contributed Assets which are personal property or fixtures are in good operating condition and repair, subject to normal wear and maintenance, are useable to support the antennae structures of BAM and the other tenants on the existing Tower Structures as of the date hereof, except for such defects as would not cost more than $25,000 to correct with respect to each such Tower Structure or more than $5,000,000 for all such Tower Structures. To BAM's knowledge, except as disclosed in Schedule 5.1.4 all of the transmitting towers, ground radials, guy anchors, transmitting buildings and related improvements, if any, located on the real property owned or leased by BAM are located entirely on such real property. Real Property. (a) Zoning. To BAM's knowledge, BAM's ownership, lease or use of the real property included in the BAM Contributed Assets or subject to Site Leases is in compliance with all applicable zoning and other land use requirements where the failure to so comply would materially limit BAM's ability to use such real property in the ordinary course of business. (b) Utility Services. The water, electric, gas and sewer utility services and the septic tank and storm drainage facilities currently available to the Tower Sites are adequate for the present use of such Tower Sites by BAM, are not being appropriated by BAM but rather are being supplied to BAM by utility companies or municipalities pursuant to valid and enforceable contracts or tariffs, and there is no condition which will result in the termination of the present access from the Tower Sites to such utility services and other facilities. (c) Access. To BAM's knowledge, BAM has obtained all Governmental Permits (where required), easements and rights-of-way which are reasonably necessary to provide vehicular and pedestrian ingress and egress to and from the Tower Sites for the purposes used by BAM in the ordinary course. To BAM's knowledge,

no action is pending or threatened which would have the effect of terminating or limiting such access. (d) Eminent Domain.

Except as set forth in Schedule 5.1.6, BAM has not received any notices from any Governmental Authority regarding any alleged Defaults relating to the ownership, use or occupancy of the BAM Contributed Assets under any applicable Laws, including Environmental Laws. Except as set forth in Schedule 5.1.6, BAM, with respect to the BAM Contributed Assets, is not presently subject to the provisions of any Court Order and there has been no Default with respect to any Court Order applicable to BAM with respect to the BAM Contributed Assets, except for such Defaults that would not have a BAM Material Adverse Effect, individually or in the aggregate. Governmental Permits. Except as set forth on Schedule 5.1.7, BAM has obtained all Governmental Permits that are required for the ownership, use or occupancy of the BAM Contributed Assets as now being conducted, all of which are in full force and effect, except where the failure to obtain any such Governmental Permit or of any such Governmental Permit to be in full force and effect would not have a BAM Material Adverse Effect, individually or in the aggregate. BAM has complied with all such Governmental Permits, except where the failure so to comply would not have a BAM Material Adverse Effect, individually or in the aggregate. Contracts. Schedule 5.1.8 identifies all Contracts of the following types to which BAM is a party, or by which it is bound, with respect to the BAM Contributed Assets (other than any Contract that is terminable by a party on not more than sixty (60) days' notice without any Liability or any Contract under which the obligation of a party (fulfilled and to be fulfilled) involves an amount of less than $50,000 (a "Minor Contract")): (a) Contracts which are Site Leases, disclosing for each the location of the related Tower Site, the identity of the lessor, the expiration date of the initial term under the lease, and the amount of the rental paid to the lessor by BAM

The Contracts listed in Schedule 5.1.8 are referred to herein as the "BAM Contracts." Except as identified in Schedule 5.1.8, BAM is not in Default under any BAM Contract in any material respect. BAM has not received any written communication from, or given any written communication to, any other party indicating that BAM or such other party, as the case may be, is in Default under any BAM Contract. To BAM's knowledge, (i) except as identified in Schedule 5.1.8, none of the other parties to any such BAM Contract is in Default thereunder in any material respect and (ii) each such BAM Contract is in full force and effect and is enforceable against the other parties thereto in accordance with its terms, except to the extent that such enforcement may be limited by applicable bankruptcy, reorganization, insolvency and other Laws of general application affecting enforcement of creditors' rights generally.

Nothing has occurred since the date of any such determination that is reasonably likely to affect adversely such qualification or exemption, or result in the imposition of excise Taxes or income Taxes on unrelated business income under the Code or ERISA with respect to any such Benefit Plan. (d) There are no pending or, to BAM's knowledge, threatened claims by or on behalf of any such Benefit Plans, or by or on behalf of any Covered Persons under any such Benefit Plans, alleging any breach of fiduciary duty on the part of BAM or any of its officers, directors or employees under ERISA or any other applicable regulations, or claiming benefit payments (other than those made in the ordinary operation of such plans), nor is there, to BAM's knowledge, any basis for any such claim.

Business Plan and Annual Budget. On or before November 30 of each year, the managers of HoldCo shall, in consultation with BAM, develop a business plan and budget for HoldCo (including HoldCo Sub and OpCo) ("Business Plan") for the following calendar year of HoldCo (and HoldCo Sub and OpCo). The Business Plan for the period between the Closing Date and December 31, 1999 is attached hereto as Exhibit 8.2.12. Each subsequent Business Plan shall be submitted to the members for review and, subject to the second following sentence, comment and shall be adopted only with the mutual consent of BAM and Bidder Member. HoldCo shall use commercially reasonable efforts to, and cause each of HoldCo Sub and OpCo to, conduct their respective businesses in accordance with the then current Business Plan. If by the first date of any year the proposed Business Plan for that year has not been adopted, the Business Plan for such year shall be deemed to be the expense portion of the Business Plan in effect for the preceding year increased, at the discretion of Bidder Member, to an amount not to exceed the sum of: (a) the average operating cost per communications tower owned by OpCo (or of which it has the economic benefit) (the "OpCo Towers") based on the most recent quarterly financial statements available as of the first day of the current year multiplied by 50% of the sum of (i) the aggregate number of OpCo Towers constructed, completed or otherwise acquired in the course of the prior year and (ii) the aggregate number of OpCo Towers

projected to be constructed, completed or otherwise acquired in the current year in the Business Plan for the prior year; and (b) the sum of (x) with respect to all contractual price increases with respect to contracts and agreements to which OpCo is a party and all increases in Taxes with respect to OpCo Towers, the amount of such increase and (y) with respect to all other expense items in the previous year's budget, (A) the amount of such expenses multiplied by (B) the sum of 1 plus an amount equal to the percentage increase in the CPI during the previous year. If BAM and Bidder Member are unable to mutually agree on the Business Plan for the year commencing January 1, 2000, the Business Plan for such year shall be deemed to be the quotient of (a) the expense portion of the initial Business Plan for the period ending December 31, 1999, increased as contemplated by the foregoing sentence, multiplied by 365 (b) divided by the number of days elapsed between the Closing Date and December 31, 1999 (including both the Closing Date and December 31, 1999). Notwithstanding the foregoing, each Business Plan that is implemented pursuant to the foregoing two paragraphs of this Section 8.2.12 because BAM and Bidder Member are unable to mutually agree on the Business Plan must provide for the payment by OpCo, prior to the allocation of revenues pursuant to such two paragraphs, of : (i) any and all costs, expenses or payments reasonably necessary to fulfill OpCo's obligations under the Global Lease Agreement; (ii) any and all costs, expenses or payments reasonably necessary to fulfill OpCo's obligations under the Build-to-Suit Agreement; (iii) any and all taxes of any kind due and owing by OpCo; (iv) any payments or expenditures required under any lease of real estate, grant of easement, right of way or similar agreement to which OpCo is a party; (v) any and all costs, expenses or payments reasonably necessary to fulfill OpCo's obligations under any lease or sublease of tower space or real estate to any third party; (vi) insurance premiums (including without limitation, any payments pursuant to premium financing) and/or deductibles of OpCo; (vii) payments to third parties for equipment or any other goods and services required to perform OpCo's obligations under existing agreements including, without limitation, payments required to satisfy any mechanics's liens; (viii) salaries, commissions, compensation, benefits, and payments or obligations of a similar nature; and (ix) any and all costs, expenses and payments required to comply with, or payable pursuant to any applicable laws, rule, regulations, ordinances, permits or licenses. Further, any such Business Plan may have the effect of reducing amounts payable under the Management Agreement so long as the Anticipated Financing remains outstanding.

Certain Contracts. Neither HoldCo, HoldCo Sub, or OpCo shall enter into any contract, agreement or arrangement (whether written or oral), other than agreements and contracts in force as of the date hereof and renewals thereof, which (a) contains provisions restricting HoldCo, HoldCo Sub or OpCo or any member thereof from competing in any business activity in any geographic area, (b) contains provisions requiring HoldCo, HoldCo Sub, or OpCo or any member thereof to deal exclusively with any third party with respect to providing any goods, services or rights to or acquiring any goods or services or rights from such third party, (c) contains provisions which are inconsistent with the obligations of HoldCo, HoldCo Sub or OpCo under any Transaction Document, or (d) provides for the purchase or sale of goods, services or rights involving an amount in excess of $10,000,000 per year in any transaction or series of similar transactions.

Any purported transfer of the Bidder HoldCo Interest in violation of this Section 9.1 shall be void. Restriction on Sales by BAM. Without the prior written consent of Bidder Member, BAM shall not, directly or indirectly, sell, assign, transfer, pledge, hypothecate, mortgage or dispose of, by gift or otherwise, or in any way encumber, the BAM HoldCo Interest unless either (a) the transfer is made to any entity or which either Bell Atlantic Corporation or BAM Inc. owns directly or indirectly all of the voting power of the outstanding capital stock (provided that (x) such entity executes an instrument reasonably satisfactory in form and substance to Bidder Member pursuant to which it agrees to be bound hereby and (y) Bell Atlantic Corporation or BAM (or the successor by merger to either) shall not thereafter at any time cease to own directly or indirectly less than all of the voting power of the outstanding capital stock of such entity), or (b) BAM has complied with the procedures described in this Article 9 and (i) the transfer is made subject to the right of first refusal described in Section 9.4 hereof or (ii) to the extent Bidder Member does not exercise its right of first refusal described in Section 9.4 hereof, the transfer is made subject to the right of participation in sales described in Section 9.5(b) hereof.

Any purported transfer of the BAM HoldCo Interest in violation of this Section 9.2 shall be void. BAM Right of First Refusal. (a) If at any time Bidder Member wishes to sell all or any part of the Bidder HoldCo Interest, Bidder Member shall submit a written offer to sell such Bidder HoldCo Interest to BAM on terms and conditions, including price, not less favorable to BAM than those on which the Bidder Member proposes to sell the Bidder HoldCo Interest to any other purchaser (the "Bidder Offer"). The Bidder Offer shall disclose the identity of the proposed purchaser or transferee, the percentage of the Bidder HoldCo Interest to be sold, the terms of the sale, any amounts owed to Bidder Member with respect to the Bidder HoldCo Interest and any other material facts relating to the sale. BAM shall respond to the Bidder Offer as soon as practicable after receipt thereof, and in all events within thirty (30) days after receipt thereof. The Bidder Offer may be revoked at any time. BAM shall have the right to accept the Bidder Offer as to all (but not less than all) of the Bidder HoldCo Interest offered thereby. In the event that BAM shall elect on a timely basis to purchase all (but not less than all) of the Bidder HoldCo Interest covered by the Bidder Offer, BAM shall communicate in writing such election to purchase to Bidder Member, which communication shall be delivered by hand or mailed to Bidder Member at the address set forth in Section 11.9 below and shall, when taken in conjunction with the Bidder Offer, be deemed to constitute a valid, legally binding and enforceable agreement for the sale and purchase of the Bidder HoldCo Interest covered thereby; provided, however, that Bidder Member may elect in its sole discretion to

terminate such agreement at any time prior to the closing of such sale and purchase, in which case such Bidder HoldCo Interest shall again become subject to the requirements of a prior offer pursuant to this Section. In the event Bidder Member terminates any such agreement prior to closing, Bidder Member shall be prohibited from consummating a transaction for the sale and purchase of the Bidder HoldCo Interest with the proposed purchaser or transferee for two (2) years from the date of such termination, and shall be prohibited from consummating a transaction for the sale and purchase of the Bidder HoldCo Interest with any other party for six (6) months from the date of such termination. In the event that any Bidder Offer includes any non-cash consideration, BAM may in its sole discretion elect to pay a cash amount equal to the fair market value of such non-cash consideration in lieu of such non-cash consideration. The closing of the sale and purchase contemplated by any agreement for the sale and purchase of any portion of the Bidder HoldCo Interest entered into between BAM and Bidder Member pursuant to this Section 9.3 shall be consummated within sixty (60) days after the date that such agreement becomes valid, legally binding and enforceable as aforesaid, subject to extension to the extent necessary to secure required approvals or consents from Governmental Authorities. Each of BAM and Bidder Member shall use its reasonable best efforts to obtain such required approvals or consents from Governmental Authorities.

Any such sale shall be to the same proposed purchaser or transferee, at not less than the price and upon other terms and conditions, if any, not more favorable to the purchaser than those specified in the Bidder Offer. If such Bidder HoldCo Interest is not sold within such ninety (90)-day period, it shall again become subject to the requirements of a prior offer pursuant to this Section. In the event that such Bidder HoldCo Interest is sold pursuant to this Section to any purchaser other than BAM, such Bidder HoldCo Interest shall continue to be subject to the restrictions imposed by this Section 9.3 with the same effect as though such purchaser were Bidder Member for purposes of this Section. Bidder Member's Right of First Refusal. (a) If at any time BAM wishes to sell all or any part of the BAM HoldCo Interest, BAM shall submit a written offer to sell such BAM HoldCo Interest to Bidder Member on terms and conditions, including price, not less favorable to Bidder Member than those on which BAM proposes to sell the BAM HoldCo Interest, as the case may be, to any other purchaser (the "BAM Offer"). The BAM Offer shall disclose the identity of the proposed purchaser or transferee, the percentage of the

BAM HoldCo Interest to be sold, the terms of the sale, any amounts owed to BAM with respect to the BAM HoldCo Interest and any other material facts relating to the sale.

In the event BAM terminates any such agreement prior to closing, BAM shall be prohibited from consummating a transaction for the sale and purchase of the BAM HoldCo Interest with the proposed purchaser or transferee for two (2) years from the date of such termination, and shall be prohibited from consummating a transaction for the sale and purchase of the BAM HoldCo Interest with any other party for six (6) months from the date of such termination. In the event that any BAM Offer includes any non-cash consideration, Bidder Member may in its sole discretion elect to pay a cash amount equal to the fair market value of such non-cash consideration in lieu of such non-cash consideration. The closing of the sale and purchase contemplated by any agreement for the sale and purchase of any portion of the BAM HoldCo Interest entered into between BAM and Bidder Member pursuant to this Section 9.4 shall be consummated within sixty (60) days after the date that such agreement becomes valid, legally binding and enforceable as aforesaid, subject to extension to the extent necessary to secure required approvals or consents from Governmental Authorities.

If such BAM HoldCo Interest is not sold within such ninety (90)-day period, such BAM HoldCo Interest shall continue to be subject to the requirements of a prior offer pursuant to this Section. In the event

that such BAM HoldCo Interest is sold pursuant to this Section to any purchaser other than Bidder Member, such portion of the BAM HoldCo Interest shall continue to be subject to the restrictions imposed by this Section 9.4 with the same effect as though such purchaser were BAM for purposes of this Section. Right of Participation in Sales. (a) If at any time Bidder Member wishes to sell all or any portion of the Bidder HoldCo Interest to any person or entity other than BAM (the "Bidder HoldCo Interest Purchaser"), BAM shall have the right to offer for sale to the Bidder HoldCo Interest Purchaser, as a condition of such sale by Bidder Member, at the same price and on the same terms and conditions as involved in such sale by Bidder Member, the same proportion of the BAM HoldCo Interest as the proposed sale represents with respect to the Bidder HoldCo Interest. BAM shall notify Bidder Member of such intention as soon as practicable after receipt of the Bidder Offer made pursuant to Section 9.3, and in all events within thirty (30) days after receipt thereof.

Any portion of the Bidder HoldCo Interest and the BAM HoldCo Interest sold pursuant to this Section 9.5 shall no longer be subject to the restrictions imposed by Sections 9.3 or 9.4 or entitled to the benefit of this Section 9.5(a).

Without the prior written consent of Bidder, BAM shall not, directly or indirectly, sell, assign, transfer, pledge (except the pledge of the BAM Retained Interest to the Lender to secure the Anticipated Financing), hypothecate, mortgage or dispose of, by gift or otherwise, or in any way encumber, the BAM Retained Interest unless either (a) the transfer is made to an entity of which either BAM or Bell Atlantic Corporation owns directly or indirectly all of the voting power of the outstanding capital stock, or (b) the transfer is made in connection with a merger or consolidation transaction to which BAM or Bell Atlantic Corporation is a party. Nomination of Director. From and after the distribution of the Bidder Contributed Shares to BAM in connection with the dissolution of HoldCo, as provided in the HoldCo Operating Agreement, upon the written request of BAM, Bidder shall, so long as BAM or its affiliates own at such time at least 7.5% of the outstanding Bidder Common Stock, expand its Board of Directors by one person and shall elect to the vacancy so created on Bidder's Board of Directors one designee of BAM. Thereafter, for so long as BAM or its affiliates own at least 7.5% of the outstanding Bidder Common Stock, at each annual meeting of the stockholders of Bidder, Bidder shall use its best efforts to nominate one designee of BAM for election as a director of Bidder if after such meeting no designee of BAM would hold office as a director of Bidder absent the election of a BAM designee as a director of Bidder at the meeting. Subject to the fiduciary duties of the Board of Directors of Bidder, Bidder shall use reasonable efforts to solicit from the stockholders of Bidder eligible to vote for the election of directors proxies in favor of the nominees selected in accordance with this Section 9.7. Registration Rights. Bidder hereby grants to BAM and its successors and assigns the registration rights contained in Exhibit 9.8 hereto which are hereby incorporated by reference in this Agreement with the same effect as if set forth herein in their entirety. Specific Performance. Each of the Parties specifically acknowledges and agrees that the remedy at law for any breach of the covenants contained in this Article 9 will be inadequate and that any other Party, in addition to any other relief available to them, shall be entitled to temporary and permanent injunctive relief without the necessity of proving actual damages. ARTICLE 10.

(a) From and after the Closing, BAM shall indemnify and hold harmless OpCo, its successors and assigns and its officers, directors, employees, agents and any Person who controls any of the foregoing within the meaning of the Securities Act (each, an "Indemnified OpCo Party") from and against any liabilities, claims, causes of action, demands, judgments, losses, costs, damages or expenses whatsoever (including reasonable attorneys', consultants' and other professional fees and disbursements of every kind, nature and description incurred by such Indemnified OpCo Party in connection therewith) (collectively, "Losses") that such Indemnified OpCo Party may sustain, suffer or incur and that result from, arise out of or relate to (i) any breach of any of the representations, warranties, covenants or agreements of BAM contained in this Agreement or (ii) any BAM Retained Liability. (b) OpCo acknowledges and agrees that BAM shall not have any Liability under any provision of this Agreement for any Loss to the extent that such Loss relates to the failure to act or any action taken by OpCo or any other Person (other than BAM or any of its Affiliates in breach of this Agreement) or any Transaction Document after the Closing Date. (c) OpCo shall take and shall cause its Affiliates to take all reasonable steps to mitigate any Loss upon becoming aware of any event which would reasonably be expected to, or does, give rise thereto, including incurring costs only to the minimum extent necessary to remedy the breach which gives rise to the Loss. (d) Nothing herein shall be deemed to limit or restrict in any manner any rights or remedies which OpCo has or may have, at law, in equity or otherwise, against BAM based on a willful misrepresentation or willful breach of any warranty, covenant or agreement by BAM hereunder. Indemnification by Bidder. (a) From and after the Closing, Bidder shall indemnify and hold harmless BAM, its successors and assigns and its officers, directors, employees, agents and any Person who controls any of the foregoing within the meaning of the Securities Act or the Exchange Act (each, an "Indemnified BAM Party") from and against any Losses that such Indemnified BAM Party may sustain, suffer or incur and that result from, arise out of or relate to any breach of any of the representations, warranties, covenants or agreements of Bidder contained in this Agreement.

(b) BAM shall take and cause its Affiliates to take all reasonable steps to mitigate any Loss upon becoming aware of any event which would reasonably be expected to, or does, give rise thereto, including incurring costs only to the minimum extent necessary to remedy the breach which gives rise to the Loss. (c) Nothing herein shall be deemed to limit or restrict in any manner any rights or remedies which BAM has or may have, at law, in equity or otherwise, against Bidder and Bidder Member based on a willful misrepresentation or willful breach of any, covenant or agreement of warranty by Bidder and Bidder Member hereunder. Indemnification by OpCo. (a) From and after the Closing, OpCo shall indemnify and hold harmless each Indemnified BAM Party from and against any Losses that such Indemnified BAM Party may sustain, suffer or incur and that result from, arise out of or relate to (i) any BAM Assumed Liability or (ii) events occurring after the Closing Date in connection with OpCo's business, including, without limitation, the use, ownership, possession or operation of the BAM Contributed Assets from and after the Closing Date. (b) BAM shall take and cause its Affiliates to take all reasonable steps to mitigate any Loss upon becoming aware of any event which would reasonably be expected to, or does, give rise thereto, including incurring costs only to the minimum extent necessary to remedy the breach which gives rise to the Loss.

Procedure for Claims. (a) Any Person that desires to seek indemnification under any provision of this Section 10 or any other provision of this Agreement providing for indemnification (each, an "Indemnified Party") shall give notice (a "Claim Notice") to each party responsible or alleged to be responsible for indemnification hereunder (an "Indemnitor") prior to any applicable Expiration Date specified below. Such Claim Notice shall briefly explain the nature of the claim and the parties known to be involved, and shall specify the amount thereof. If the matter to which a claim relates shall not have been resolved as of the date of the Claim Notice, the Indemnified Party shall estimate the amount of the claim in the Claim Notice, but also specify therein that the claim has not yet been liquidated (an "Unliquidated Claim"). If an Indemnified Party gives a Claim Notice for an Unliquidated Claim, the Indemnified Party shall also give a second Claim Notice (the "Liquidated Claim Notice") within sixty (60) days after the matter giving rise to the claim becomes finally resolved, and the Second Claim Notice shall specify the amount of the claim. Any failure to give a Claim Notice in a timely manner pursuant to this Section 10.5(a) shall not limit the obligation of the Indemnitor under this Section 10, except to the extent such Indemnitor is prejudiced thereby and except as otherwise provided in Section 10.8. Each Indemnitor to which a Claim Notice is given shall respond to any Indemnified Party that has given a Claim Notice (a "Claim Response") within thirty (30) days (the "Response Period") after the later of (a) the date that the Claim Notice is given or (b) if a Claim Notice is first given with respect to an Unliquidated Claim, the date on which the Liquidated Claim Notice is given. Any Claim Notice or Claim Response shall be given in accordance with the notice requirements hereunder, and any Claim Response shall specify whether or not the Indemnitor giving the Claim Response disputes the claim described in the Claim Notice. If any Indemnitor fails to give a Claim Response within the Response Period, such Indemnitor shall be deemed not to dispute the claim described in the related Claim Notice. If any Indemnitor elects not to dispute a claim described in a Claim Notice, whether by failing to give a timely Claim Response or otherwise, then the amount of such claim shall be conclusively deemed to be an obligation of such Indemnitor. If the Indemnitor notifies the Indemnified Party in the Claim Response that it disputes the claim made by the Indemnified Party, then the Indemnitor and the Indemnified Party shall endeavor in good faith for a period of thirty (30) days to settle and compromise such claim, and if unable to agree on any settlement or

compromise, such claim for indemnification shall be settled by arbitration in accordance with the provisions of Section 11.1 of this Agreement, and any Loss established by reason of such settlement, compromise or arbitration shall be deemed to be finally determined. (b) Any Loss that is finally determined in the manner set forth in Section 10.5(a) shall be paid by the Indemnitor to the Indemnified Party within thirty (30) days after (a) the last day of the Claim Response Period or (b) the date on which such settlement, compromise or arbitration described in the last sentence of Section 10.5(a) shall have been deemed to be finally determined, as the case may be. If any Indemnitor fails to pay all or part of any indemnification obligation when due, then such Indemnitor shall also be obligated to pay to the applicable Indemnified Party interest on the unpaid amount for each day during which the obligation remains unpaid at an annual rate equal to the Prime Rate plus two percent (2%) per annum, and the Prime Rate in effect on the first (1st) business day of each calendar quarter shall apply to the amount of the unpaid obligation during such calendar quarter. Certain Limitations. Notwithstanding anything to the contrary in this Agreement, except as provided below in this Section 10.6, (i) OpCo shall be entitled to indemnification hereunder with respect to the breach of a representation, warranty, covenant or agreement by BAM only when the aggregate of all Losses to such Indemnified OpCo Parties from all such breaches exceeds on a cumulative basis $7,500,000 (the "Deductible Amount"), and then only to the extent of such excess amount, and (ii) BAM shall not be liable under this Agreement for an aggregate amount in excess of $195,000,000 (the "Maximum Indemnification"). The foregoing limitations with respect to the Maximum Indemnification shall not apply, however, to any willful misrepresentation or willful breach of warranty by BAM. Notwithstanding the other provisions of this Section 10, no Indemnified OpCo Party shall be entitled to seek indemnification under this Section 10 for any individual fact, circumstance, condition or occurrence that results in a breach of a representation or warranty that involves Losses of less than $25,000. Notwithstanding the foregoing provisions of this Section 10.6, the indemnification of OpCo by BAM for BAM Retained Liabilities pursuant to Section 10.1(a)(ii) shall not be subject to the Deductible Amount or any other deductible, the Maximum Indemnification limitation, or the limitation under the immediately preceding sentence. Non-Third Party Claims. In no event shall BAM and its Affiliates, Bidder and its Affiliates, or Bidder Member and its Affiliates be liable to the other party hereto for any special, incidental or consequential damages incurred by such other party and caused by or arising out of any breach of any representation, warranty, covenant or agreement contained in this Agreement or the other Transaction Documents. Claims Period. Any claim for indemnification under this Section 10 shall be made by giving a Claim Notice under Section 10.5 on or before the applicable "Expiration Date" specified below in this Section 10.8, if any, or the claim under this Section 10 shall be invalid. The following claims shall have the following respective "Expiration Dates": (i) June 30, 2000, with respect to any claims that are not specified in the succeeding clause (ii); or (ii) the date on which the applicable statute of limitations expires with respect to any claim for Losses related to a (x) breach of any covenant or agreement or (y) a breach of warranty or misrepresentation under Sections 5.1.1, 5.1.2, 5.2.1, 5.2.2, 5.3.1, 5.3.2 and 5.3.11. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, there shall be no

Expiration Date with respect to (A) any claim by an Indemnified OpCo Party for Losses related to any BAM Retained Liability, or (B) any claim by an Indemnified BAM Party for Losses related to any BAM Assumed Liability . So long as an Indemnified Party gives a Claim Notice for an Unliquidated Claim on or before the applicable Expiration Date, if any, such Indemnified Party shall be entitled to pursue its rights to indemnification regardless of the date on which such Indemnified Party gives the related Liquidated Claim Notice. Third Party Claims. An Indemnified Party that desires to seek indemnification under any part of this Section 10 with respect to any actions, suits or other administrative or judicial proceedings (each, an "Action") that may be instituted by a third party shall give each Indemnitor prompt notice of a third party's institution of such Action and tender defense of such Action to the Indemnitor, with counsel reasonably satisfactory to such Indemnified Party; provided, however, that such Indemnified Party shall have the right to participate at its own expense in the defense of such Action; and provided, further, that the Indemnitor shall not consent to the entry of any judgment or enter into any settlement, that (x) does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a complete release therefrom, or (y) provides for injunctive or other non-monetary relief affecting the Indemnified Party, except with the written consent of such Indemnified Party (which consent shall not be unreasonably withheld, delayed or conditioned). The Indemnified Party shall render all assistance and cooperation to the Indemnitor (at Indemnitor's sole expense) which the Indemnitor may request in defense of any such Action including, without limitation, the making of witnesses and documents available for depositions, interrogatories and court proceedings. Any failure to give prompt notice and to tender the defense of an Action pursuant to this Section 10.9 shall not bar an Indemnified Party's right to claim indemnification under this Section 10, except to the extent that an Indemnitor shall have been harmed by such failure. Effect of Investigation or Knowledge. Except as otherwise provided herein, all covenants, agreements, representations and warranties made herein or in any agreement, instrument or certificate delivered pursuant to this Agreement shall not be deemed to be waived or otherwise affected by any investigation at any time made by or on behalf of any party hereto. No claim for a breach of representation or warranty shall be made by any Indemnified OpCo Party under Section 10.1(a) or any Indemnified BAM Party under Sections 10.2 (a), 10.3(a) or 10.4(a) if (i) such claim is based on an event occurring prior to the Closing (whether or not also occurring prior to the date of this Agreement), (ii) either (a) such event was disclosed by BAM, Bidder or Bidder Member, as the case may be, prior to the Closing in a writing which describes such event in reasonable detail or (b) Bidder, Bidder Member or BAM, as the case may be, had actual knowledge of such event or such misrepresentation or breach of warranty prior to the Closing, and (iii) the Closing occurs. Losses Net of Insurance, Etc. The amount of any Loss for which indemnification is provided under this Agreement shall be net of (i) any tax benefit (such as a deduction, credit or deferral) actually realized from any Loss, (ii) any amounts recovered by the Indemnified Party pursuant to any indemnification by or indemnification agreement with any third party, and (iii) any insurance proceeds or other cash receipts or sources of reimbursement received as an offset against such Loss. Each of OpCo and BAM shall make any claims for indemnification from a third party or insurance proceeds available to offset against such Loss and for which it will seek indemnification hereunder, and to pursue such claims in good faith. If the amount to be netted hereunder from any Loss is determined after payment by the Indemnitor of any amount otherwise required to be paid to an Indemnified Party pursuant to this Section 10.11, the Indemnified Party shall repay to the Indemnitor, promptly after such determination, any amount that the Indemnitor would not have had to pay pursuant to this Section 10.11 had such determination been made at the time of such payment.

Sole Remedies. Subject to the provisions of Sections 10.1(c), 10.2(c), 10.3(c) and 10.4(c), the indemnification provisions set forth in this Section 10 constitute the sole and exclusive post-Closing remedies of the parties hereto with respect to Losses arising out of or relating to this Agreement, and shall preclude the assertion after the Closing by any party of any other rights, or the seeking of any other remedies against any other party for claims arising out of or relating to this Agreement. ARTICLE 11. MISCELLANEOUS Dispute Resolution. In the case of any dispute, controversy or claim between or among the parties hereto related to this Agreement or the transactions contemplated hereby or the other documents referred to herein, except for disputes related to obtaining the equitable remedies of specific performance, an injunction or a restraining order (a "Dispute"), the parties will use the procedures set forth in this Section 11.1, in lieu of any party pursuing other available remedies and as the sole remedy, to resolve the Dispute. Submission to Arbitration. Any Dispute will be settled by arbitration before three arbitrators in accordance with the Rules of the American Arbitration Association ("AAA") then in effect and as modified by this Section 11.1 or by further agreement of the parties. In addition to what is allowed by the Rules of the AAA, discovery may be conducted according to the Federal Rules of Civil Procedure, to be enforced by the AAA, and if necessary, by a court having jurisdiction. Any such arbitration will be conducted in New York, New York, unless otherwise agreed by BAM and Bidder Member. The arbitrators will be selected from a panel of persons (such as retired jurists, distinguished legal or business professionals, and similar persons) knowledgeable in the specific areas which may be relevant to the claim, who have had more than ten (10) years of relevant experience in such areas, who have previously acted as arbitrators, and who are generally held in the highest regard among professionals in fields or businesses related or pertinent to such area. Judgment upon the award rendered by the arbitrators may be entered pursuant to applicable arbitration statutes. Authority of Arbitrators. The arbitrators will have no authority to award punitive damages nor any other damages not measured by the prevailing party's actual damages, and may not, in any event, make any ruling, finding or award that does not conform to the terms and conditions of this Agreement. Confidentiality. Neither the parties hereto nor the arbitrators may disclose the existence or results of any arbitration under this Agreement or any evidence presented during the course of the arbitration without the prior written consent of the parties, other than by entry of a judgment upon any arbitration award. Cost of Arbitration. The arbitrators will have the authority to award to the prevailing party its attorneys' fees and costs incurred in any arbitration. Absent any such award, each party will bear its own costs incurred in the arbitration. If any party hereto refuses to submit to arbitration any Dispute required to be submitted to arbitration pursuant to this Section 11.1, and instead commences any other proceeding, including, without limitation, litigation (except to the extent otherwise expressly provided in this Agreement), then the party who seeks enforcement of the obligation to arbitrate will be entitled to its attorneys' fees and costs incurred in any such proceeding.

Bidder's Reasonable Best Efforts Regarding Bidder Member's Performance. For so long as Bidder Member is a direct or indirect subsidiary of Bidder, Bidder will use its reasonable best efforts to cause Bidder Member to timely and completely observe and perform all of its agreements, covenants and obligations under this Agreement and all of the other Transaction Documents and all renewals, modifications, amendments and extensions thereof; provided, however, that in no event shall this Section 11.2 obligate Bidder to make any capital contributions or loan or otherwise provide any financial assistance to, or on behalf of, Bidder Member. Survival of Representations and Warranties. All representations and warranties made by the parties in this Agreement or pursuant hereto shall survive the Closing until the Expiration Date. Transfer Taxes. BAM and Bidder Member shall each pay one-half of all state and local sales, documentary and other transfer Taxes, if any, due as a result of the contribution, purchase, sale or transfer of the BAM Contributed Assets hereunder. Termination. (a) Anything herein or elsewhere to the contrary notwithstanding, this Agreement may be terminated by written notice of termination at any time before the Closing Date only as follows: (i) by mutual consent of Bidder and BAM; (ii) by BAM, upon written notice to Bidder given at any time after June 30, 1999 (or such later date as shall have been specified in a writing authorized on behalf of Bidder and BAM) if all of the conditions precedent set forth in Article 7 hereof have not been met; (iii) by Bidder, upon written notice to BAM given at any time after June 30, 1999 (or such later date as shall have been specified in a writing authorized on behalf of Bidder and BAM) if all of the conditions precedent set forth in Article 7 hereof have not been met; (iv) by Bidder at any time prior to the Closing if BAM shall have breached any of its representations, warranties or other obligations under this Agreement in any respect which would have a material and adverse effect on either (A) the Contributed BAM Assets and Assumed BAM Liabilities taken as a whole, or (B) on the ability of BAM to consummate the transactions contemplated hereby and such breach shall not have been cured within thirty (30) days after notice of such breach; or (v) by BAM at any time prior to the Closing if Bidder or Bidder Member shall have breached any of its representations, warranties or other obligations under this Agreement in any material respect and such breach shall not have been cured within thirty (30) days after notice of such breach.

(b) In the event of the termination and abandonment hereof pursuant to the provisions of this Section 11.5, this Agreement (except for Sections 5.1.15, 5.3.4, 6.1.6, 6.1.7, 6.2.4, 6.2.6 and 11.6 which shall continue) shall become void and have no effect, without any liability on the part of any of the parties or their directors, officers, stockholders, partners or representatives in respect of this Agreement, unless the termination was the result of the representations and warranties of a party being materially incorrect when made or the material breach by such party of a covenant hereunder in which event the party whose representations and warranties were incorrect or who breached such covenant shall be liable to the other party for all costs and expenses of the other party in connection with the preparation, negotiation, execution and performance of this Agreement. Expenses. Except as otherwise provided in this Agreement, each party hereto shall pay its own expenses incidental to the preparation of this Agreement, the carrying out of the provisions of this Agreement and the consummation of the transactions contemplated hereby. Contents of Agreement; Parties in Interest; etc. This Agreement and the other Transaction Documents set forth the entire understanding of the parties hereto with respect to the transactions contemplated hereby. This Agreement shall not be amended or modified except by written instrument duly executed by each of the parties hereto. Any and all previous agreements and understandings between or among the parties regarding the subject matter hereof, whether written or oral, are superseded by this Agreement and the other Transaction Documents. Any term or provision of this Agreement, or any breach thereof, may be waived at any time by the party entitled to the benefit thereof by a written instrument duly executed by such party; provided, however, that any waiver by any party of a breach of any term or provision of this Agreement shall not operate or be construed as a waiver of any subsequent breach, whether or not similar, unless such waiver specifically states that it is to be construed as a continuing waiver. Assignment and Binding Effect. This Agreement may not be assigned by any party hereto without the prior written consent of the other parties, provided that (i) BAM may assign its rights hereunder to any other wholly-owned (direct or indirect) subsidiary of BAM or Bell Atlantic Corporation or to any transferee of its entire remaining BAM HoldCo Interest, in each case, in compliance with Section 9.2, and (ii) each of Bidder and Bidder Member may assign any of its rights hereunder to any wholly-owned (direct or indirect) subsidiary of Bidder Member or Bidder or to any transferee of its entire remaining Bidder HoldCo Interest, in each case, in compliance with Section 9.1. No such assignment shall relieve BAM, Bidder or Bidder Member of their respective obligations hereunder except that in connection with a transfer by either Bidder Member or BAM of its entire remaining Bidder HoldCo Interest or BAM HoldCo Interest, respectively, made in accordance with the provisions of Article 9, the transferring party shall be relieved only of its obligations under Articles 8 and 9 of this Agreement. For purposes of the foregoing, a transfer by merger by Bidder or BAM (whether or not Bidder or BAM is the surviving corporation), or any direct or indirect parent corporation of Bidder or BAM, shall not be deemed to be an assignment for purposes of this Section 11.8. Subject to the foregoing, all of the terms and provisions of this Agreement shall be binding upon and inure to the benefit of and be enforceable by the permitted successors and assigns of BAM, Bidder and Bidder Member. All references herein to any party shall be deemed to include any successor to such party, including any corporate successor.

For the purpose of determining Members entitled to notice of, or to vote at, any meeting of Members or any adjournment of the meeting, or Members entitled to receive payment of any distribution, or to make a determination of Members for any other purpose, the date on which notice of the meeting is mailed or the date on which the resolution declaring the distribution or relating to such other purpose is adopted, as the case may be, shall be the record date for the determination of Members.

At an adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally noticed. The Members present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal during the meeting of Members whose absence would cause less than a quorum.

(b) If an indemnified representative is entitled to indemnification in respect of a portion, but not all, of any liabilities to which such person may be subject, the Company shall indemnify such indemnified representative to the maximum extent for such portion of the liabilities. (c) The termination of a proceeding by judgment, order, settlement or conviction or upon a plea of nolo contendere or its equivalent shall not of itself create a presumption that the indemnified representative is not entitled to indemnification.

The financial ability of an indemnified representative to repay an advance shall not be a prerequisite to the making of such advance. Section V.4 Payment of Indemnification. An indemnified representative shall be entitled to indemnification within thirty (30) days after a written request for indemnification has been delivered to the secretary of the Company. Section V.5 Arbitration.

selected by the Company, the second of whom shall be selected by the Indemnified Representative and the third of whom shall be selected by the other two arbitrators. In the absence of the AAA, or if for any reason arbitration under the arbitration rules of the AAA cannot be initiated, and if one of the parties fails or refuses to select an arbitrator or the arbitrators selected by the Company and the Indemnified Representative cannot agree on the selection of the third arbitrator within thirty (30) days after such time as the Company and the Indemnified Representative have each been notified of the selection of the other's arbitrator, the necessary arbitrator or arbitrators shall be selected by the presiding judge of the court of general jurisdiction in such metropolitan area. (b) Each arbitrator selected as provided in this Section is required to be or have been a manager, director or executive officer of a limited liability company, corporation or other entity whose equity securities were listed during at least one (1) year of such service on the New York Stock Exchange or the American Stock Exchange or quoted on the National Association of Securities Dealers Automated Quotations System.

The indemnification, contribution and advancement of expenses provided by or granted pursuant to this Article shall continue as to a person who has ceased to be an indemnified representative in respect of matters arising prior to such time, and shall inure to the benefit of the heirs, executors, administrators, personal representatives, successors and permitted assigns of such a person.

(b) The initial Tax Book Value of any assets contributed by a Member to the Company shall be the agreed fair market value of such assets, increased by the amount of liabilities of the contributing Member assumed by the Company in connection with the contribution of such assets plus the amount of any other liabilities to which such assets are subject.

Notwithstanding the compromise, a creditor of the Company who extends credit, after entering into this Operating Agreement or an amendment hereof which, in either case, reflects the obligation, and before the amendment hereof to reflect the compromise, may enforce the original obligation to the extent that, in extending credit, the creditor reasonably relied on the obligation of a Member to make a contribution or return. A conditional obligation of a Member to make a contribution or return money or other property to the Company may not be enforced unless the conditions of the obligation have been satisfied or waived as to or by such Member. Conditional obligations include contributions payable upon a discretionary call of the Company prior to the time the call occurs. Section VI.5 Capital Accounts. A separate Capital Account will be maintained for each Member. The initial Capital Accounts shall consist solely of the initial capital contributed by the Members pursuant to Section 6.3. BAM's Capital Account will be reduced immediately -25-

after the BAM Capital Distribution by the amount distributed to BAM (and the Transferring Partnerships). BAM's Capital Account balance after the BAM Capital Distribution will be reflected on the books and records of the Company. Notwithstanding any other provision hereof, the Company shall determine and adjust the Capital Accounts in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv).

(b) Member Nonrecourse Deductions. Loss attributable (under Treasury Regulation Section 1.704-2(i)(2)) to "partner nonrecourse debt" (within the meaning of Treasury Regulation Section 1.704-2(b)(4)) shall be allocated, in accordance with Treasury Regulation Section 1.704- 2(i)(1), to the Member who bears the economic risk of loss with respect to the debt to which the Loss is attributable. The Members acknowledge that the Anticipated Financing shall be treated as "partner nonrecourse debt." -26-

(d) Qualified Income Offset. Losses and items of income and gain shall be specially allocated when and to the extent required to satisfy the "qualified income offset" requirement within the meaning of Treasury Regulation Section 1.704-1(b)(2)(ii)(d). Section VI.10 Other Allocations. (a) Allocations when Tax Book Value Differs from Tax Basis. When the Tax Book Value of a Company asset is different from its adjusted tax basis for income tax purposes, then, solely for federal, state and local income tax purposes and not for purposes of computing Capital Accounts, income, gain, loss, deduction and credit with respect to such assets ("Section 704(c) Assets") shall be allocated among the Members to take this difference into account in accordance with the principles of IRC Section 704(c), as set forth herein and in the Treasury Regulations thereunder and under IRC Section 704(b). Except to the extent otherwise required by final Treasury Regulations, the calculation and allocations eliminating the differences between Tax Book Value and adjusted tax basis of the Section 704(c) Assets shall be made on an asset-by-asset basis without curative or remedial allocations to overcome the "ceiling rule" of Treasury Regulation Section l.704-1(c)(2) and Treasury Regulation Section 1.704-3(b)(1). (b) Change in Member's Interest. (1) If during any fiscal year of the Company there is a change in any Member's Membership Interest, then for purposes of complying with IRC Section 706(d), the determination of Company items allocable to any period shall be made by using any method permissible under IRC Section 706(d) and the Regulations thereunder as may be determined by the Managers. (2) The Members agree to be bound by the provisions of this Section 6.10(b) in reporting their shares of Company income, gain, loss, and deduction for tax purposes. (c) Allocations on Liquidation. Notwithstanding any other provision of this Article VI to the contrary, in the taxable year in which there is a liquidation of the Company, after the allocations in Sections 6.8 and 6.9 hereof, the Capital Accounts of the Members will, to the extent possible, be brought to the amount of the liquidating distributions to be made to them under Section 9.5 hereof by allocations of items of profit and loss and, if necessary, by guaranteed payments (within the meaning of Code Section 707(c)) credited to the Capital Account of a Member whose Capital Account is less than the amount to be distributed to it and -27-

debited from the Capital Account of the Member whose Capital Account is greater than the amount to be distributed to it. Section VI.11 Limitations Upon Liability of Members. Except as otherwise expressly and specifically provided in or required by the Certificate or this Operating Agreement, the personal liability of each Member to the Company, to the other Members, to the creditors of the Company or any third party for the losses, debts or liabilities of the Company shall be limited to the amount of its Capital Contribution which has not theretofore been returned to it as a distribution (including a distribution upon liquidation). For purposes of the foregoing sentence, distributions to a Member shall first be deemed a return of its Capital Contribution. No Member shall at any time be liable or held accountable to the Company, to the other Members, to the creditors of the Company or to any other third party for or on account of any negative balance in its Capital Account. ARTICLE VII DISTRIBUTIONS Section VII.1 Net Cash From Operations and Distributions.

(b) For purposes of this Operating Agreement, "Net Cash From Operations" means the gross cash proceeds from Company operations less the portion thereof used to, or expected to be used to, pay expenses, debt payments, capital improvements, replacements and increases to reserves therefor. "Net Cash From Operations" shall not be reduced by depreciation, amortization, cost recovery deductions or similar allowances, but shall be increased by any reductions to reserves previously established. Section VII.2 Limitations on Distributions. (a) The Company shall not make a distribution to a Member to the extent that at the time of the distribution, after giving effect to the distribution, all liabilities of the Company, other than liabilities to Members on account of their interests in the Company and liabilities for which the recourse of creditors is limited to specified property of the Company, exceed the fair value of the assets of the Company, except that the fair value of property that is subject to a liability for which the recourse of creditors is limited shall be included in the assets of the Company only to the extent that the fair value of that property exceeds that liability. -28-

(b) A Member who receives a distribution in violation of subsection (a), and who knew at the time of the distribution that the distribution violated this section, shall be liable to the Company for the amount of the distribution. A Member who receives a distribution in violation of this section, and who did not know at the time of the distribution that the distribution violated this section, shall not be liable for the amount of the distribution. Subject to subsection (c), this subsection shall not affect any obligation or liability of a Member under other applicable law for the amount of a distribution. (c) A Member who receives a distribution from the Company shall have no liability under this Section, the Act or other applicable law for the amount of the distribution after the expiration of three (3) years from the date of the distribution unless an action to recover the distribution from such Member is commenced prior to the expiration of the said three (3)-year period and an adjudication of liability against such Member is made in the action.

For purposes of the foregoing, CCIC Member shall not be deemed to have indirectly transferred any of the CCIC HoldCo Interest if CCIC or any other parent corporation of CCIC Member is a party to any merger or consolidation transaction, whether or -29-

not such parent corporation is the surviving entity in such merger. Any purported transfer of the CCIC HoldCo Interest in violation of this Section 8.1 shall be void. Section VIII.2 Restriction on Transfers by BAM. Without the prior written consent of CCIC Member, BAM shall not have the right, directly or indirectly, to sell, assign, transfer, pledge, hypothecate, mortgage or dispose of, by gift or otherwise, or in any way encumber, any of the interest in the Company held by BAM (the "BAM HoldCo Interest") unless either (a) the transfer is made to any entity of which either Bell Atlantic Corporation or BAM owns directly or indirectly all of the voting power of the outstanding capital stock (provided that (x) such entity executes an instrument reasonably satisfactory in form and substance to CCIC Member pursuant to which it agrees to be bound hereby and (y) Bell Atlantic Corporation or BAM (or the successor by merger to either) shall not thereafter at any time cease to own directly or indirectly less than all of the voting power of the outstanding capital stock of such entity), or (b) BAM has complied with the procedures described in this Article VIII and (i) the transfer is made subject to the right of first refusal described in Section 8.4 hereof or (ii) to the extent CCIC Member does not exercise its right of first refusal described in Section 8.4 hereof, the transfer is made subject to the right of participation in sales described in Section 8.5(b) hereof. For purposes of the foregoing, BAM shall not be deemed to have indirectly transferred any of the BAM HoldCo Interest if Bell Atlantic Corporation or any other parent corporation of BAM is a party to any merger or consolidation transaction, whether or not such parent corporation is the surviving entity in such merger. Any purported transfer of the BAM HoldCo Interest in violation of this Section 8.2 shall be void. Section VIII.3 BAM Right of First Refusal of Transfer. (a) If at any time CCIC Member wishes to sell all or any part of the CCIC HoldCo Interest, CCIC Member shall submit a written offer to sell such CCIC HoldCo Interest to BAM on terms and conditions, including price, not less favorable to BAM than those on which CCIC Member proposes to sell the CCIC HoldCo Interest to any other purchaser (the "CCIC Offer"). The CCIC Offer shall disclose the identity of the proposed purchaser or transferee, the percentage of the CCIC HoldCo Interest to be sold, the terms of the sale, any amounts owed to CCIC Member with respect to the CCIC HoldCo Interest and any other material facts relating to the sale. BAM shall respond to the CCIC Offer as soon as practicable after receipt thereof, and in all events within thirty (30) days after receipt thereof. The CCIC Offer may be revoked at any time. BAM shall have the right to accept the CCIC Offer as to all (but not less than all) of the CCIC HoldCo Interest offered thereby.

(b) In consideration of the distribution to CCIC Member of the HoldCo Sub membership interest, CCIC Member shall make a payment to BAM in an amount equal to the Allocated Share of the Fair Market Value of such membership interest in HoldCo Sub, which reflects the underlying value of the assets held by each of HoldCo and OpCo; provided, however, that in the event that CCIC Member makes the election set forth in Section 9.5(a)(2)(iii), then (x) "nineteen percent (19.0%)" shall be substituted for "fourteen percent (14.0%)" in subsection (i) of the definition of "Allocated Share" in Section 1.1; and (y) the determination of "Allocated Share" pursuant to subsection (ii) of such definition shall be performed appropriately taking into account the substitution described in (x) above. At the option of CCIC Member, such payment shall be made either (i) in cash or (ii) in shares of CCIC Common Stock, with the number of shares of CCIC Common Stock determined by dividing the Allocated Share by the average trading price of CCIC Common Stock in the sixty (60) trading days preceding payment. For purposes of this Section, "Fair Market Value" of the HoldCo Sub membership interest shall be calculated as follows: (i) BAM and CCIC Member shall negotiate in good faith to determine Fair Market Value and (ii) if BAM and CCIC Member fail to agree on Fair Market Value within thirty (30) days after such trigger event, the Fair Market Value of the HoldCo Sub membership interest shall be determined pursuant to the appraisal process described below: (1) Not later than five (5) days after the expiration of the period during which BAM and CCIC Member are to negotiate in good faith to determine the Fair Market Value, BAM and CCIC Member shall each select an appraiser (which may or may not be a Qualified Investment Banking Firm (as hereinafter defined)) and shall give the other party notice of such selection. Each of such appraisers (the "Original Appraisers") shall determine the fair market value of the HoldCo Sub membership interest at the time such appraiser renders its written appraisal. -37-

(2) Each Original Appraiser shall deliver its written appraisal to the party retaining such Original Appraiser within twenty (20) days following the date of the selection of both Original Appraisers. Such written appraisals shall be exchanged by BAM and CCIC Member at the offices of Morgan, Lewis & Bockius LLP, or such other place as the parties shall designate, at 10:00 a.m. local time on the twenty-first (21st) day following the date of the selection of both Original Appraisers. In the event that the Original Appraisers agree on the fair market value, the Fair Market Value shall be such agreed-upon amount. In the event that the Original Appraisers do not agree on the fair market value, (i) if the higher of the two valuations is not more than one hundred ten percent (110%) of the lower valuation of the Original Appraisers, the Fair Market Value shall be the mean of the two valuations, and (ii) if the higher of the two valuations is greater than one hundred ten percent (110%) of the lower valuation, the Original Appraisers shall elect a Qualified Investment Banking Firm which shall independently calculate the fair market value within fifteen (15) days of such election. If the Original Appraisers cannot agree upon a third appraiser within five (5) days following the end of the twenty (20) day period referred to above, then the third appraiser shall be a Qualified Investment Banking Firm appointed by the AAA. Neither BAM nor CCIC Member nor either of the Original Appraisers shall provide the third appraiser, directly or indirectly, with a copy of the written appraisal of either of the Original Appraisers, an oral or written summary thereof, or the valuation determined by either of the Original Appraisers, either orally or in writing. The valuation of the third appraiser will be compared with the two valuations of the Original Appraisers, and the valuation farthest from the third valuation will be disregarded. The Fair Market Value shall be the mean of the two remaining valuations. (3) BAM and CCIC Member shall give to the Original Appraisers and the third appraiser, and shall cause HoldCo Sub and OpCo to give to the appraisers, free and full access to and the right to inspect, during normal business hours, all of the premises, properties, assets, records, contracts and other documents relating to HoldCo Sub and OpCo and shall permit them and cause HoldCo Sub and OpCo to permit them to consult with the officers, employees, accountants, counsel and agents of HoldCo Sub, OpCo, BAM and CCIC Member for the purpose of making such investigation of HoldCo Sub and OpCo as they shall desire to make. Furthermore, BAM and CCIC Member shall furnish to the Original Appraisers and the third appraiser, and shall cause HoldCo Sub and OpCo to furnish to such appraisers, all such documents and copies of documents and records and information with respect to the affairs of HoldCo Sub and OpCo and copies of any working papers relating thereto as they shall from time to time reasonably request. (4) "Qualified Investment Banking Firm" means any firm engaged in providing corporate finance, merger and acquisition, and business valuation services and deriving revenues therefrom (excluding any revenues derived from merchant banking activities) of at least $25 million during its last completed fiscal year, but excluding, however, any firms which received more than $250,000 in fees during the preceding twenty-four (24) calendar months from BAM or CCIC Member or their respective affiliates and any firms selected by BAM or CCIC Member as an Original Appraiser. -38-

Each subsequent Business Plan shall be submitted to the Members for review and, subject to the second following sentence, comment, and shall be adopted only with the mutual consent of BAM and CCIC Member. The Company shall use commercially reasonable efforts to, and cause each of HoldCo Sub and OpCo to, conduct their respective businesses in accordance with the then current Business Plan.

completed or otherwise acquired in the current year in the Business Plan for the prior year; and (b) the sum of (x) with respect to all contractual price increases with respect to contracts and agreements to which OpCo is a party and all increases in Taxes with respect to OpCo Towers, the amount of such increase and (y) with respect to all other expense items in the previous year's budget, (A) the amount of such expenses multiplied by (B) the sum of one (1) plus an amount equal to the percentage increase in the CPI during the previous year. If BAM and CCIC Member are unable to mutually agree on the Business Plan for the year commencing January 1, 2000, the Business Plan for such year shall be deemed to be the quotient of (a) the expense portion of the initial Business Plan for the period ending December 31, 1999, increased as contemplated by the foregoing sentence, multiplied by three hundred sixty-five (365) (b) divided by the number of days elapsed between the Effective Date and December 31, 1999 (including both the Effective Date and December 31, 1999). Notwithstanding the foregoing, each Business Plan that is implemented pursuant to the foregoing two paragraphs of this Section 10.3 because BAM and CCIC Member are unable to mutually agree on the Business Plan must provide for the payment by OpCo, prior to the allocation of revenues pursuant to such two paragraphs, of: (i) any and all costs, expenses or payments reasonably necessary to fulfill OpCo's obligations under the Global Lease; (ii) any and all costs, expenses or payments reasonably necessary to fulfill OpCo's obligations under the Build-to-Suit Agreement; (iii) any and all taxes of any kind due and owing by OpCo; (iv) any payments or expenditures required under any lease of real estate, grant of easement, right of way or similar agreement to which OpCo is a party; (v) any and all costs, expenses or payments reasonably necessary to fulfill OpCo's obligations under any lease or sublease of tower space or real estate to any third party; (vi) insurance premiums (including without limitation, any payments pursuant to premium financing) and/or deductibles of OpCo; (vii) payments to third parties for equipment or any other goods and services required to perform OpCo's obligations under existing agreements including, without limitation, payments required to satisfy any mechanics's liens; (viii) salaries, commissions, compensation, benefits, and payments or obligations of a similar nature; and (ix) any and all costs, expenses and payments required to comply with, or payable pursuant to any applicable laws, rule, regulations, ordinances, permits or licenses.

(b) The Company shall not be obligated to pay any fees or other compensation to the Tax Matters Partner in its capacity as such.

The Tax Matters Partner shall be entitled to rely on the advice of legal counsel as to the nature and scope of its responsibilities and authority as Tax Matters Partner, and any act or omission of the Tax Matters Partner pursuant to such advice shall in no event subject the Tax Matters Partner to liability to the Company or any Member. Section X.6 Tax Audits/Special Assessments.
