The parties further acknowledge and agree that the Total Reimbursement Amount shall be the sole compensation due and payable to Vendor for Work and other Services performed pursuant to the BTS Agreement and this Agreement in connection with the In Process BTS Sites and for transferring each In Process BTS Site as required hereby. The Total Reimbursement Amount shall be determined, as follows: (1) As to each Milestone Site, the "Milestone Site Reimbursement Amount" shall be the amount payable for each Milestone Site and shall be calculated as of the Milestone Cut off Date, based on the fixed price amounts (the "Fixed Price Amounts") set forth on the Milestone Reimbursement Schedule for the Completed Milestones or Deemed Completed Milestones for each Milestone Site. Except for any amounts in Dispute, which shall be paid within ten (10) Business Days 6 after resolution of such Dispute, the Milestone Site Reimbursement Amount shall be paid on the Milestone Transition Date.

(3) As to the Construction Sites, the "Total Construction Site Reimbursement Amount" shall be an amount equal to the lesser of (1) the aggregate sum of the Budgeted Amounts for all accepted Construction Sites as evidenced by the Construction Site Budget less any SBCW Reimbursement Amount for each such Construction Site which is also a SBCW Site (other than any Construction Site which is rejected by SBCW in accordance with the terms of this Agreement) or (2) the sum of the Construction Site Reimbursement Amounts for all Construction Sites not rejected by SBCW in accordance with the terms of this Agreement. With regard to the foregoing, attached hereto is the Construction Site Budget which provides a Budgeted Amount for each Construction Site and the aggregate Budgeted Amount(s) for all Construction Sites (as of the date hereof). The parties acknowledge that the Budgeted Amounts as set forth on the Construction Site Budget are Vendor's good faith estimates, as to each Construction Site, of the direct third party costs to Complete each of the Construction Sites PLUS the Allocated Developmental Overhead Reimbursement Amount. The Budgeted Amount for each Construction Site includes an estimated Allocated Developmental Overhead Reimbursement Amount as to each Construction Site. Except for any amounts in Dispute, which shall be paid within five (5) Business Days after resolution of such Dispute, and any credit to SBCW for a delay as set forth, in Article II, Section (a)(2) above, the Construction Site Reimbursement Amount shall be paid on the Construction Site Closing Date. 7 (c) CINGULAR WORK.

In addition, SBCW shall be entitled to the applicable SBCW Reimbursement Amount with respect to any Completed BTS Site which is also an SBCW Site. (d) IN PROCESS BTS SITES. The parties acknowledge and agree that the In Process BTS Sites will be Completed and/or Vendor's or the Vendor Affiliate's interest therein transferred to SBCW or the designated Cingular Group Member as provided in this Agreement and shall not be added to or governed by the BTS Sublease, the BTS Agreement or related documents, except as provided this Agreement. ARTICLE IV DISPUTE RESOLUTION; FURTHER ASSURANCES; PRORATIONS (a) DISPUTED COSTS. Without limiting the foregoing, SBCW shall have the right to dispute and review any charge as to any Completed CA/NV Site or any In Process BTS Site to be included in the calculation of the Total CA/NV Site Purchase Price or any portion of the Total Reimbursement Amount (herein, a "Disputed Cost"). In connection with any Disputed Cost, SBCW shall be entitled to request and receive further supporting documentation evidencing such Disputed Cost, including copies of paid invoices and lien waivers (if applicable) to which such Disputed Cost relates. Any dispute regarding a Disputed Cost (a "Dispute"), shall be resolved in accordance with these Dispute Procedures. The parties agree to appoint representatives to facilitate resolution of any such Dispute as set forth below: (1) SBCW shall within the applicable period set forth in Article III herein, give written notice (the "Dispute Notice") to Vendor of any Dispute. The Dispute Notice shall include a short description of the Dispute and shall be sent to Vendor via confirmed (A) facsimile or (B) email. The designated representatives shall meet (in person or by conference call) as often as the parties reasonably deem necessary to discuss the Dispute in an effort to resolve the Dispute without the necessity of any formal proceeding. The parties' designated representatives shall have their first meeting, pursuant to this subsection, within five (5) business days from receipt of the Dispute Notice by Vendor. (2) In the event that such representatives are unable to resolve the Dispute within fifteen (15) business days after the receipt of the Dispute Notice, or if after at least two (2) meetings and ten (10) business days following the receipt of the Dispute Notice, either party determines in good faith that such representatives are unlikely to be able to resolve such Dispute, then within three (3) business days of written notice by either party of an impasse, the Dispute shall be referred by written notice to an 8 executive officer of each of such parties for consideration or, if either party so elects, the parties shall submit the Dispute as to all Disputed Costs to arbitration in accordance with the Arbitration Procedures attached hereto as SCHEDULE IX. (b) FURTHER ASSURANCES/COOPERATION. Without limiting the foregoing but without expanding or enlarging Vendor's obligations hereunder, Vendor agrees to furnish all such information, take all such other action, and cooperate with SBCW as SBCW may require in order to effectuate an orderly and systematic termination or Completion of the Services, Work and other Vendor duties, obligations and activities with respect to the In Process BTS Sites and Completed CA/NV Sites, as applicable. Vendor for itself and applicable Vendor Affiliates and SBCW for itself and applicable Cingular Group Members agree to execute whatever instruments, in addition to the Assignment Agreement, either party may reasonably request to effectuate or evidence the orderly transition and transfer of the In Process BTS Sites and Completed CA/NV Sites, as applicable. Vendor will, from time to time at SBCW's request, use Vendor's reasonable efforts to assist SBCW and the applicable Cingular Group Members in securing the consent of any ground lessors or other third parties, that may be required to effect or perfect the transition of any In Process BTS Site or Completed CA/NV Site, as applicable, in accordance with the provisions of this Agreement (it being agreed that if the parties are unable to obtain any such consent of a ground lessor, Vendor's interest in the applicable In Process Site, notwithstanding anything to the contrary contained in this Agreement, shall not be assigned to SBCW or a Cingular Group Member). To the extent it is legally able to do so, Vendor for itself and applicable Vendor Affiliates will, from time to time at SBCW's request, execute and deliver such bills of sale, assignments and other instruments, conveyances and transfers (all without representation or warranty, except for the warranty of title set forth in Section V(b)(2) hereof and other representations and warranties only as set forth herein, in the Assignment Agreement and the related individual assignment agreements) as are reasonably necessary in order to more fully and effectively confirm the transition and transfer of Vendor's or the applicable Vendor Affiliate's right, title and interest in and to the In Process BTS Sites and Completed CA/NV Sites, as applicable including, without limitation, as to each Completed CA/NV Site, Construction Site, and Milestone Site that has reached the Ground Lease Milestone, executing and delivering, on the Applicable Site Transfer Date, duly executed assignments (substantially in the form of the Assignment Agreement attached), and/or memoranda of Ground Leases, in each case, in proper recordable form for the State in which such BTS Site is located, to more fully perfect and vest leasehold title to those BTS Sites in SBCW or the applicable Cingular Group Member. With respect to the Completed CA/NV Sites and the Construction Sites, as applicable, SBCW and Vendor (and applicable Vendor's Affiliates) shall cooperate with each other toward effecting a smooth and orderly transition in the property management, lease administration and site operation of those BTS Sites (to the extent theretofore commenced) from Vendor to SBCW or the applicable Cingular Group Member. SBCW and Vendor shall use good faith efforts to structure the transfer of Vendor's or the applicable Vendor Affiliate's right, title and interest in and to the In Process BTS Sites (or any of them) and/or Completed CA/NV Sites by Vendor to SBCW 9 (or SBCW's designee) in a manner that will minimize the transaction costs associated with such transfer, including without limitation, any sales tax or real property transfer taxes. Without limiting the foregoing, the transfers of the In Process BTS Sites and/or Completed CA/NV Sites, as applicable, shall be accomplished either by (i) the transfer of such BTS Sites directly to SBCW or the applicable Cingular Group Member each pursuant to the Assignment Agreement, as applicable to such BTS Sites; or at the option of Vendor or SBCW, (ii) Vendor or the applicable Vendor Affiliate shall transfer, pursuant to the Assignment Agreement and other related documents, the Completed CA/NV Sites and/or the In Process BTS Sites to one (or more than one, if required in order to accommodate multiple closing dates), newly formed limited liability companies (collectively, "NewCo", which term may include as to the Completed CANV Sites, the Company (as defined in the NewCo Purchase Agreement)) to be formed by Vendor immediately prior to the transfer of such BTS Sites to NewCo and SBCW (or the applicable Cingular Group Member) shall thereafter acquire 100% of the membership interests in NewCo in a manner and for a price consistent with the terms of this Agreement (as if the transfers were being made directly SBCW or the applicable Cingular Group) and otherwise reasonably acceptable to the parties. The parties will each be responsible for 50% of the applicable transfer tax and sales tax associated with the transfers referred to herein. PROVIDED THAT as part of the Assignment Agreement, Vendor and Vendor Affiliates shall, among other things, cause NewCo to, jointly and severally represent and warrant to SBCW and the applicable Cingular Group Members with respect to NewCo substantially the same representations and warranties with respect to the Company (as defined in the SS NewCo Purchase Agreement) set forth in Sections 2.1(b), 2.2(b), 2.2(c) (except to the extent covered in Section V(a) (3) hereof), 2.3, 2.4, 2.5, 2.6 (not including the representations and warranties contained in the second and third sentence of section 2.6(a) of the SS NewCo Purchase Agreement) which are otherwise covered herein and 2.7 (collectively, the "Entity Representations") of the SS NewCo Purchase Agreement. Further, (a) Vendor and Vendor Affiliates shall, jointly and severally, indemnify SBCW and Cingular Group Members for, among other things, breaches of any of the Entity Representations (which shall, for indemnification purposes, be deemed not to include references to "material" or "material adverse effect"), (b) such Entity Representations shall survive indefinitely and (c) indemnification claims made with respect to breaches of such Entity Representations shall not be subject to any limitations (including thresholds, deductibles or maximums), except that in no event shall one party be liable to the other party for any special, incidental, consequential or other such damages. (c) NEGATIVE COVENANTS. From the date of this Agreement until the Applicable Site Transfer Date as to the In Process BTS Sites and Completed CA/NV Sites, as applicable, except as otherwise expressly contemplated herein, Vendor covenants and agrees that it will not do or agree or commit to do, any of the following: (i) impose, or suffer the imposition or existence, on Vendor's or any Vendor Affiliate's interest, if any, in any In Process BTS Sites or Completed CA/NV Sites of any Lien (other than a Permitted Lien and security interests in favor of Vendor's senior lenders, which security interests will be released at or prior to the Applicable Site Transfer Date) or permit any such Lien to exist, except for such Liens that the Vendor will cure by 10 bonding or otherwise discharging on or prior to the Applicable Site Transfer Date; (ii) sell, lease, mortgage or otherwise dispose of Vendor's or any Vendor Affiliate's interest, if any, in any In Process BTS Sites and Completed CA/NV Sites (other than the granting of security interests in favor of Vendor's senior lenders, which security interests will be released at or prior to the Applicable Site Transfer Date); or (iii) except as expressly required under Article III hereunder, enter into, modify or amend in any material respect or terminate any Ground Lease, Site Contract or Third Party Collocation Agreement or waive, release or compromise in any material respect or assign any material rights or claims relating thereto. (d) PRORATIONS. As soon as practicable after the Applicable Site Transfer Date, real estate and personal property taxes ("Taxes") attributable to those BTS Sites being transferred shall be apportioned as of the Applicable Site Transfer Date for each. Such apportionments shall be made pro rata on a per diem basis as of the Effective Date so that all such Taxes attributable to the period prior to the Applicable Site Transfer Date are for the account of Assignor; and all such Taxes attributable to the period on and after the Applicable Site Transfer Date are for the account of SBCW or applicable Cingular Group Member. Taxes shall initially be determined based on the previous year's taxes and shall later be adjusted to reflect the current year's Taxes when the tax bills are finally rendered. The parties shall fully cooperate to avoid, to the extent legally possible, the payment of duplicate Taxes, and each party shall furnish, at the request of the other, proof of payment of any Taxes or other documentation which is a prerequisite to avoiding payment of a duplicate tax. In the event that either party (the "Payor") pays a Tax for which the other party (the "Payee") is obligated in whole or in part under this Section, the Payor shall present to the Payee evidence of payment and a statement setting forth the Payee's proportionate share of such Tax, and the Payee shall promptly pay such share to the Payor. In the event either Party (the "Recipient") receives refunds of a Tax to which the other Party (the "Beneficiary") is entitled in whole or in part under this Agreement, the Recipient shall promptly pay such share to the Beneficiary. In the event there exists as of the Applicable Site Transfer Date any pending appeals of ad valorem tax assessments with regard to any of the BTS Sites being transferred, the continued prosecution and/or settlement of such appeals shall be subject to the direction and control of Assignee with respect to assessments for the year within which the Assignment occurs. The parties agree that the following items shall be also apportioned between Vendor and SBCW, as of the Applicable Site Transfer Date, as to the Completed CA/NV Sites and Construction Sites: (a) rents and revenues under all Third Party Collocation Agreements; (b) base rent, license fees, revenue sharing payments or other charges due to landlords, lessors or licensors under the Ground Lease and (c) utility charges relating to Tower lighting. Such apportionments shall be made pro rata on a per diem basis as of the Applicable Site Transfer Date so that all such rents, revenues, charges and payments attributable to the period prior to the Applicable Site Transfer Date are for the account of Vendor; and all such rents, revenues, charges and payments attributable to the period from and after the Applicable Site Transfer Date are for the account of SBCW with such adjustments (and adjustments pursuant to the first paragraph of this Section 4(d)) to be made as of the Applicable Site Transfer Date by the party that on a net basis owes money 11 to the other party under this paragraph (d) by wire transfer of immediately available funds to such accounts as such other party shall direct in writing. The parties shall fully cooperate to avoid, to the extent legally possible, making duplicate payments to ground lessors or other counter-parties under the Ground Leases and to other third parties.
