(b) The Consideration shall be due and payable, at each Closing, as follows: (i) with respect to each Included Site being conveyed at a Closing, TowerCo shall pay to the applicable Sublessor Entity, an amount equal to the prepaid Rent for such Site (provided for in Section 10 of the SBCW Sublease), which amount shall be payable in a Cash Portion and in a Stock Portion; (ii) the amount of cash to be paid at each Closing shall be paid in immediately available funds and shall be equal to the product of (a) the Cash Portion and (b) the amount of prepaid Rent calculated in accordance with (i) above; and (iii) the number of shares of Parent Stock to be issued at each Closing shall be equal to the product of (a) the Stock Portion and (b) the amount of prepaid Rent calculated in accordance with subsection (i) above, divided by the Share Price. 11 (c) The Parent Stock is to be issued to direct or indirect wholly owned subsidiaries of SBC Communications Inc. that own interests in the Applicable Sublessor Entities. The Parent Stock shall be subject to an adjustment to be calculated and paid in accordance with the provisions of this Section 3.2(c) through Section 3.2(i) below. (d) If the End Date occurs prior to the consummation of a Change of Control, then within two Business Days following the End Date, TowerCo Parent shall pay the End Date Adjustment Payment to SBCW. The End Date Adjustment Payment may be paid, at TowerCo Parent's option, in cash or in Parent Stock or in any combination of the foregoing. If TowerCo Parent elects to pay some or all of the End Date Adjustment Payment in Parent Stock, TowerCo Parent shall (x) issue to SBCW the number of shares of Parent Stock equal to (i) the amount payable in Parent Stock divided by (ii) the Current Market Price (as of the End Date), and (y) pay the balance, if any, of the End Date Adjustment Payment to SBCW in cash. Notwithstanding the foregoing, if TowerCo Parent elects to pay some or all of the End Date Adjustment Payment in Parent Stock, the maximum number of shares of Parent Stock TowerCo Parent will be required to issue in order to satisfy its obligation with respect to such payment shall not exceed the product of (x) 10,783,179 shares of Parent Stock and (y) a fraction the numerator of which is equal to the SBCW End Date Stock Amount, and the denominator of which is equal to the aggregate number of shares of Parent Stock issued to SBCW and SBCW Affiliates under Section 3.2(b). (e) If a Change of Control is consummated prior to the End Date, then immediately prior to the consummation of such Change of Control, TowerCo Parent shall pay the Change of Control Payment to SBCW. The Change of Control Payment may be paid, at TowerCo Parent's option, in cash or in Parent Stock or in any combination of the foregoing. If TowerCo Parent elects to pay some or all of the Change of Control Payment in Parent Stock, TowerCo Parent shall (x) issue to SBCW the number of shares of Parent Stock equal to (i) the amount payable in Parent Stock divided by (ii) the Change of Control Price, and (y) pay the balance, if any, of the Change of Control Payment, to SBCW in cash. Notwithstanding the foregoing, if TowerCo Parent elects to pay some or all of the Change of Control Payment in Parent Stock, the maximum number of shares of Parent Stock TowerCo Parent will be required to issue in order to satisfy its obligation with respect to such payment shall not exceed the product of (x) 10,783,179 shares of Parent Stock and (y) a fraction the numerator of which is equal to the SBCW Change of Control Stock Amount, and the denominator of which is equal to the aggregate number of shares of Parent Stock issued to SBCW and SBCW Affiliates under Section 3.2(b). (f) If any Liquidity Event occurs prior to the earlier to occur of (x) the consummation of a Change of Control and (y) the End Date, then within two Business Days following any such Liquidity Event, TowerCo Parent shall pay a Liquidity Event Payment to SBCW. The Liquidity Event Payment may be paid, at TowerCo Parent's option, in cash or in Parent Stock or in any combination of the foregoing. If TowerCo Parent elects to pay some or all of the Liquidity Event Payment in Parent Stock, TowerCo Parent shall (x) issue to SBCW the number of shares of Parent Stock equal to (i) the amount payable in Parent Stock divided by the (ii) Liquidity Event Price, and (y) pay the balance, if any, of the Liquidity Event Payment to SBCW in cash. Notwithstanding the foregoing, if TowerCo Parent elects to pay some or all of the Liquidity Event Payment in Parent Stock, the maximum number of shares of Parent Stock TowerCo Parent will be required to issue in order to satisfy its obligation with respect to such payment shall not exceed the product of (x) 10,783,179 shares of Parent Stock and (y) a fraction the numerator of which is equal to the SBCW Liquidity Event Stock Amount, and the denominator of which is equal to the aggregate number of shares of Parent Stock issued to SBCW and SBCW Affiliates under Section 3.2(b). 12 (g) The Cash Portion of each payment under this Section 3.2 shall be made by wire transfer of immediately available funds through the Federal Reserve System to an account designated in writing by SBCW for the benefit of the applicable Sublessor Entities. To the extent any payment under this Section 3.2 to a Sublessor Entity is payable in Parent Stock, each payment shall be evidenced by a certificate issued directly to SBCW (or, as applicable, a direct or indirect wholly owned subsidiary of SBC Communications Inc.). (h) No fractional shares of Parent Stock shall be issued pursuant to this Section 3.2 and an amount in cash (if any) shall be paid in lieu of any fractional part of a share otherwise resulting from the terms of this Section 3.2 equal to such fractional part of a share multiplied by the relevant Share Price, Current Market Price, Change of Control Price or Liquidity Event Price, as applicable. (i) There will be no obligation for TowerCo Parent to pay any adjustment payment to SBCW under this Section 3.2 for events arising after the End Date Adjustment Payment or the Change of Control Payment. SECTION 3.3. Consents Under Ground Leases. SBCW and TowerCo shall use commercially reasonable efforts to obtain from each Ground Lessor from whom consent is required a written consent to (i) SBCW's subleasing of such Site to TowerCo and (ii) the further sublease of portions of the Site by TowerCo to third party tenants whose primary business is the provision of "radio transmission and/or communication services" or terms of similar meaning reasonably acceptable to TowerCo (each, a "Ground Lessor Consent") without making any concessions to the Ground Lessor in terms of Ground Rent or revenue sharing arrangements. TowerCo shall be actively involved with SBCW in all material aspects of the efforts to obtain any required Ground Lessor Consent. If SBCW is unable, with the participation and cooperation of TowerCo, to obtain any required Ground Lessor Consent by the applicable Closing, the parties shall continue using commercially reasonable efforts to obtain such Ground Lessor Consent in accordance with this Section 3.3; provided, that if the parties subsequently obtain such Ground Lessor Consent as to any Site, the Closing for such Site shall take place at the Closing next succeeding the date on which such Ground Lessor Consent is obtained, or, if the Final Closing has occurred, within six (6) months after the Final Closing at a time agreed by the parties; provided further, no Closings for such Sites shall occur after the expiration of such six (6) month period, unless the parties otherwise agree. SBCW and TowerCo shall mutually agree on the form of letter to be submitted to the Ground Lessors requesting the aforedescribed consents and shall each have the right to approve any modifications to such form proposed by any Ground Lessor and the final form of such consent. 13 ARTICLE IV CLOSINGS SECTION 4.1. Closings. (a) Subject to prior termination of this Agreement by SBCW pursuant to Article XIV, the consummation of the transfer and conveyance of the Subleased Interests and other transactions contemplated by this Agreement shall occur in multiple closings (individually, a "Closing", and collectively, the "Closings"), and each such Closing shall take place at the offices of King & Spalding, 1185 Avenue of the Americas, New York New York 10036, at such times and on such dates (each, the "Closing Date") as contemplated under Sections (b) and (c) below and as modified pursuant to the terms hereof (the "Closing Schedule").

(c) The parties shall use commercially reasonable efforts to include in each Closing at least two hundred fifty (250) Sites, whether as an Included Site or Excluded Site, including, without limitation, any Sites deferred pursuant to Section 4.6 from the previous Closings. (d) SBCW shall provide to TowerCo a list of Sites ("Closing Sites") to be included in a particular Closing, and any changes to Annex A or the Disclosure Schedule with respect to those Sites, sufficiently in advance of the applicable Closing Date such that, taking into account the number of Closing Sites, TowerCo will be able, with the exercise of reasonable diligence, to review the information included on such list (including any matters shown in, or any changes to, Annex A or the Disclosure Schedule), to determine whether the conditions set forth in Article XII of this Agreement have been satisfied (including any required Ground Lessor Consents) with respect to the Closing Sites and to prepare with respect to such Sites those portions of the Site Designation Supplements which TowerCo is obligated to prepare, in each case prior to such Closing Date. In addition, the parties shall, promptly after the date hereof, use good faith efforts to agree on procedures to effect an orderly transition in the operation and maintenance of the Sites from SBCW or the applicable Sublessor Entity to TowerCo. Notwithstanding the foregoing, the parties agree to use their good faith efforts to consummate the transactions contemplated by this Agreement as expeditiously as reasonably possible, subject to the provisions of Section 4.1(b) of this Agreement. 14 SECTION 4.2.

Notwithstanding anything to the contrary contained herein, (i) any fees, costs and expenses incurred by or on behalf of TowerCo for the services ordered or requested by TowerCo for which such Sublessor Entity is not liable under the Transaction Documents shall be the responsibility of and shall be paid for by TowerCo and (ii) any fees, costs and expenses incurred by or on behalf of any Sublessor Entity for services ordered or requested by such Sublessor Entity for which such Sublessor Entity is expressly liable under the Transaction Documents shall be the responsibility of and shall be paid for by such Sublessor Entity. SECTION 4.4. Further Assurances; Corrections. (a) At each Closing, and from time to time thereafter, each Sublessor Entity shall do all such additional and further acts, and shall execute and deliver all such additional and further instruments, certificates and documents, as TowerCo may reasonably require fully to vest in and assure to TowerCo full right, title and interest in and to the Subleased Interests to the full extent contemplated by this Agreement and otherwise to effectuate the consummation of the transactions contemplated by this Agreement. Each of the parties hereto will cooperate with the others and execute and deliver to the other parties such other instruments and documents and take such other actions as may be reasonably requested from time to time by any other party as necessary to carry out, evidence and confirm the intended purposes of this Agreement. (b) If in the review of any Site Designation Supplement either party identifies any corrections that in either party's judgment necessitate further revisions to Exhibit B, C or D to such Site Designation Supplement, the parties may at either party's request effect the correction of such Exhibit B, C or D, and defer the recordation of such Site Designation Supplement until such revisions are made, for up to thirty (30) days. (c) In addition, with respect to the Included Sites, the parties shall have the right to review and make corrections, if necessary, to any and all exhibits to the Site Designation Supplements applicable to such Included Sites after the applicable Closing. After making any such corrections, TowerCo shall re-record any such Site Designation Supplements to reflect such corrections, if requested by the applicable Sublessor Entity. 16 (d) If after any Closing any party discovers that the name of the Sublessor Entity as set forth in any Site Designation Supplement is incorrect, the applicable Sublessor Entity shall re-execute such Site Designation Supplement in such a manner as to correct such name, and TowerCo shall re-record such Site Designation Supplement, unless the parties agree that such re-recordation is not necessary. The foregoing obligation shall survive the Closing in respect of which such Site Designation Supplement was executed for a period of six (6) months. (e) The Sublessor Entity shall have the right, at its sole expense, to cause any amendment to the Site Designation Supplement to be recorded. In addition, the parties shall cooperate with each other to cause changes to be made in the documentation for any Site, and in the Site Designation Supplement for such Site, if such changes are requested by the Sublessor Entity to evidence any permitted changes in the Reserved Space or Subleased Interest respecting such Site, including, without limitation changes in such Sublessor Entity's antennas or other parts of its communications facility at such Site. Such obligation shall survive any Closing without limitation. SECTION 4.5. Site Designation Supplements. Prior to the applicable Closing Date, TowerCo shall, collect the data relating to the applicable Existing Sites, adequately describe such Existing Sites and prepare Exhibits B, C and D for all Site Designation Supplements relating to such Existing Sites, all in accordance with the terms thereof. The parties agree that, as between the parties, the description of Existing Sites shall be sufficient to adequately describe the Subleased Interests. In addition, where any discrepancy in Exhibits B, C or D requires verification in the field, including without limitation verification as to the number of antennas, height of antennas, location of antennas or location of antenna mounting hardware, the parties shall provide adequate resources and personnel to resolve such discrepancy within thirty (30) days after the applicable Closing. SECTION 4.6. Deferral of Closings; Updating of Representations. (a) Each Sublessor Entity will have the right to defer the Closing as to any Site to a later Closing by virtue of (i) the failure of such Site to satisfy any condition to the obligations of TowerCo respecting such Site (including, without limitation, the failure to obtain any Ground Lessor Consent or other third party consent), or (ii) the breach by the applicable Sublessor Entity of any Real Estate Representation as to such Site. If by the Final Closing, the applicable Sublessor Entity fails, after the exercise of reasonable efforts, to cause any such unsatisfied (and unwaived) condition to be satisfied or to cure any such (unwaived) breach of a Real Estate Representation, such Site shall constitute an Excluded Site. TowerCo shall notify SBCW prior to the applicable Closing of any Site in the event that TowerCo believes that SBCW or any applicable Sublessor Entity has not satisfied any condition in this Agreement to its obligations to acquire the Subleased Interest in such Site, including, without limitation, by virtue of a breach of a Real Estate Representation as to such Site. The applicable Sublessor Entity will have the right to cure any such breach of a representation, warranty or covenant and/or remedy such condition, and defer the Closing of such Site to facilitate such cure, as provided above. 17 (b) As soon as reasonably practicable prior to the date scheduled for any Closing pursuant to the Closing Schedule, the applicable Sublessor Entity shall disclose in writing any material information, known to such Sublessor Entity without additional inquiry, that is required to (x) be provided pursuant to any representation or warranty made by a Sublessor Entity pursuant to Article VI or (y) cause any Real Estate Representation with respect to any Existing Site to be true and correct in all material respects and to modify, amend or supplement such Real Estate Representation, including without limitation: (i) to set forth exceptions to any such representations and warranties, where such exceptions were not theretofore set forth in this Agreement or any Schedule hereto, or (ii) to reflect any lease, sublease or license that becomes an Existing Lease entered into after the date of this Agreement in the ordinary course of business consistent with past practices and matters related thereto. The applicable Sublessor Entity shall provide any such disclosure that relates to such Sublessor Entity and does not constitute a Real Estate Representation prior to the first Closing in which any Sites of such Sublessor Entity is included. Any such disclosure shall be deemed to create and constitute a portion of, and all such disclosures together shall be, the "Disclosure Schedule". Any Existing Site in respect of which the applicable Sublessor Entity makes any disclosure pursuant to this Section 4.6(b) may, at TowerCo's option, be deferred to a later Closing Date pursuant to Section 4.6(a), where the matters so described would have a Material Adverse Effect on such Existing Site. The sole remedy of TowerCo in respect of any such disclosure as to any Site shall be to cause such Site, at the applicable Sublessor Entity's option pursuant to this Section 4.6, to be an Excluded Site hereunder or to defer the Closing for such Site to a later Closing Date. SECTION 4.7. Re-Recordation. Whenever in this Agreement either party is required or has the right to record or re-record any document, including without limitation any Site Designation Supplement, Ground Lease or a memorandum thereof, such party shall, or shall cause the agent effecting such recordation to, deliver a copy of the document to the other party promptly after receipt thereof, and in any event contemporaneously with its first delivery thereof to the recording party. SECTION 4.8. Substitution of Sites. Notwithstanding anything to the contrary herein, SBCW may at any time amend Annex A to substitute a Site which has become an Excluded Site with another Site in a similar market with a similar structural design capacity, in which case such Site shall constitute an Existing Site hereunder (each, a "Substitute Site"). The Rent and Option Purchase Price Amount for such Substitute Site shall be calculated in accordance with the methodology used to calculate the Rent and Option Purchase Price Amount with respect to the Sites listed on Annex A. SECTION 4.9. Value Adjustments. (a) Notwithstanding anything to the contrary herein, at any Closing occurring after the second Closing and prior to the Final Closing, if the average Rent per Site paid by TowerCo for all Sites to be included in the applicable Closing and all Included Sites included in all prior Closings exceeds $368,842, then TowerCo shall have the right to require SBCW to defer the Closing as to any Site or number of Sites in accordance with clause (c) below such that the average Rent per Site paid by TowerCo for all Sites included in the applicable Closing and all Included Sites included in all prior Closings does not exceed $368,842. 18 (b) Notwithstanding anything to the contrary herein, if the average Rent per Site paid by TowerCo for Sites to be included in the Final Closing and all Included Sites included in all prior Closings exceeds $352,077, then TowerCo shall have the right to require SBCW to designate any Site or number of Sites to be Excluded Sites in accordance with clause (c) below, such that the average Rent per Site paid by TowerCo for all Sites included in the Final Closing and all Included Sites included in all prior Closings does not exceed $352,077. (c) TowerCo and SBCW shall mutually agree on the Sites with respect to which Closing shall be deferred in accordance with clause (a) above or which shall be designated as Excluded Sites in accordance with clause (b) above, or if TowerCo and SBCW cannot mutually agree on such Sites, the Sites with respect to which Closing shall be deferred in accordance with clause (a) above or which shall be designated as Excluded Sites in accordance with clause (b) above shall consist first of Sites otherwise to be included in the applicable Closing having the highest amount of aggregate Rent and continuing with Sites having decreasing amounts of aggregate Rent thereafter. (d) TowerCo and SBCW agree to cooperate to structure each Closing occurring during the three months prior to the Final Closing such that upon the Final Closing the average Rent per Site paid by TowerCo for the aggregate of all Included Sites will not exceed $352,077. ARTICLE V additional agreements SECTION 5.1. Expenses.

SECTION 5.2. Brokers. Each Sublessor Entity hereby represents and warrants to TowerCo that, except Goldman, Sachs & Co. which is an advisor to SBCW and the Sublessor Entities, no broker or finder has acted on its behalf in connection with this Agreement or the transactions contemplated herein and agrees to indemnify TowerCo Indemnitees from and against any and all claims or demands for commissions or other compensation by any broker, finder or similar agent claiming to have been employed by or on behalf of SBCW, including, without limitation, Goldman, Sachs & Co.

Risk of Loss and Insurance. Between the date of this Agreement and each Closing, the risks and obligations of ownership and loss of the Subleased Interests with respect to the Sites subject to such Closing and the correlative rights against insurance carriers and third parties shall belong to the applicable Sublessor Entity. In the event of the damage or destruction of all or a substantial portion of the Subleased Interests prior to any Closing, the affected Sites shall become Excluded Sites unless the parties agree to the contrary. SECTION 5.4. Condemnation. In the event of the taking of any part of the Subleased Interest of any Site, or any interest therein, by eminent domain proceedings, or the commencement or bona fide threat of the commencement of any such proceedings, prior to any Closing, the affected Sites shall become Excluded Sites unless the parties agree to the contrary. SECTION 5.5. Publicity. Except as required by applicable Laws or any applicable stock exchange rules, all press releases and other public announcements with respect to the subject matter hereof, including the time, form and content of such release or announcement, shall be made only with the mutual written agreement of TowerCo and SBCW; provided, however, that any disclosure required to be made under applicable Law may be made only if a party required to make such disclosure has determined in good faith that it is necessary to do so and has used its reasonable best efforts, prior to the issuance of the disclosure, to provide the other parties with a copy of the proposed disclosure and to discuss the proposed disclosure with the other parties. SECTION 5.6. TowerCo's Access and Inspection. SBCW and the other Sublessor Entities shall provide TowerCo and its authorized representatives (i) reports as to the Sites in electronic form, to the extent reasonably available and (ii) reasonable access during normal business hours from and after the date hereof until the Final Closing (as such date may be extended in accordance with Section 3.3) to the books and records of SBCW or such Sublessor Entity, as applicable, relating to the Subleased Interests and for physical inspection of the Subleased Interest, for the purpose of making such investigation as TowerCo may reasonably desire, and each such party shall reasonably promptly furnish TowerCo such information concerning the Subleased Interests as TowerCo may reasonably request. 20 SECTION 5.7.

Without the prior written consent of the other parties, no party hereto may take any intentional action that would cause the conditions precedent to the obligations of the parties hereto to effect the transactions contemplated hereby not to be fulfilled, including, without limitation, takings or causing to be taken any action that would cause the representations and warranties made by such party herein not to be true, correct and complete as of each Closing. SECTION 5.8. Governmental Filings. (a) The parties shall make, or cause to be made, all filings and submissions required to be made to any Government in connection with the transactions contemplated by this Agreement. (b) Each party hereto agrees to use commercially reasonable efforts to comply with all legal requirements which may be imposed on such party with respect to the transactions contemplated by the Transaction Documents and to obtain all consents, orders and approvals that may be or become necessary for the consummation of the transactions contemplated by the Transaction Documents and each party shall furnish to the other parties such necessary information and reasonable assistance as other parties may reasonably request in connection with the preparation of necessary filings or submissions to any governmental or other regulatory agency in promptly seeking to obtain all such consents, orders and approvals. SECTION 5.9. Confidentiality. (a) The parties acknowledge and agree that in the course of their discussions and negotiations of the Transaction Documents and the transactions contemplated herein, a party hereto (the "Disclosing Party") may already have disclosed or may hereafter disclose Confidential Information (as defined below) to one or more of the other parties hereto (each, a "Disclosee"). Each party agrees that if the transactions contemplated herein are not consummated, it will return to the Disclosing Party all documents and other written information furnished to it. Each party further agrees to maintain the confidentiality of any and all Confidential Information of a Disclosing Party and not disclose or give any Confidential Information to any Person or use such Confidential Information, provided, however, that the foregoing obligations will not apply to: (i) any information which was lawfully known by the Disclosee free of any obligation of confidentiality to any Person prior to its disclosure by the Disclosing Party; (ii) any information which was in the public domain prior to the disclosure thereof, (iii) any information which comes into the public domain through no fault of the Disclosee; (iv) any information which is disclosed to the Disclosee by a third party, other than an Affiliate, having the legal right to make such disclosure; (v) any information which is required to be disclosed by Order of any Forum or as required by Law, or (vi) TowerCo's disclosure on a confidential basis of Confidential Information to third parties if reasonably related to TowerCo's Permitted Use of the Sites as contemplated in the Transaction Documents, provided that TowerCo shall be liable for any breach by a third party of the confidentiality provisions in this Section 5.9 in the event TowerCo provided Confidential Information to such third party. Without limiting the generality of the foregoing, each party agrees that, when acting as a Disclosee, it will (a) restrict the disclosure of the Confidential Information of the Disclosing Party to those employees, advisors, agents and financing sources of Disclosee who require such information for the purposes contemplated hereunder, (b) notify all of its employees, advisors, agents and financing sources to whom Confidential Information of the Disclosing Party is disclosed not to use or disclose such Confidential Information in violation of this Agreement, (c) prevent use or disclosure by its employees, advisors, agents and financing sources of the Confidential Information of the Disclosing Party, except as provided herein, and (d) promptly inform the Disclosing Party of any use or disclosure of the Confidential Information of the Disclosing Party, whether intentional or not, which violates the provisions of this Section and of which Disclosee has any knowledge. 21 (b) For purposes of this Section 5.9, "Confidential Information" means any and all technical, business, and other information which is (i) possessed or hereafter acquired by a Disclosing Party and (ii) derives economic value, actual or potential, from not being generally known to Persons other than the Disclosing Party, including, without limitation, technical or non-technical data, compositions, devices, methods, techniques, drawings, inventions, processes, financial data, financial plans, lists of actual or potential customers or suppliers, information regarding the business plans and operations of the Disclosing Party, and the existence of discussions and negotiations between the parties hereto relating to the terms hereof. The provisions of this Section 5.9 shall survive any termination of this Agreement for any reason and shall remain in full force and effect from and after the Initial Closing Date. (c) TowerCo acknowledges and agrees that the databases respecting the Sites maintained on behalf of SBCW or a Sublessor Entity are owned by SBCW or such Sublessor Entity and constitute trade secrets of SBCW or such Sublessor Entity. Any data from such databases provided to TowerCo may be used by TowerCo in accordance with the terms of this Agreement, including without limitation Section 5.9. SECTION 5.10. Real Estate Matters. (a) Prior to the applicable Closing, TowerCo shall notify SBCW if the Ground Lease or a memorandum thereof has not been recorded for any Site. TowerCo shall use its commercially reasonable efforts to effect such recordation, at its sole cost and expense, except where prohibited by Law or the terms of the applicable Ground Lease. The applicable Sublessor Entity shall execute documents reasonably requested by TowerCo to effect such recordation, and shall cooperate with TowerCo in pursuing such recordation. (b) The applicable Sublessor Entity and, after the applicable Closing, TowerCo shall each have the right to place, each at its sole cost and expense, accurate signage on each Site to put third parties on notice of its interest in such Site, subject to compliance with applicable Laws and any Ground Lease for the Site in question. 22 (c) Notwithstanding anything to the contrary contained herein, if TowerCo is unable to record any unrecorded Ground Lease or memorandum thereof in respect of any Site, or otherwise to protect the applicable Sublessor Entity's interest in such Site and at any time thereafter the applicable Sublessor Entity loses its interest under the Ground Lease by virtue of a foreclosure of a prior Mortgage on the fee interest of such Site, TowerCo will have no claim against SBCW or the Sublessor Entity in respect thereof. (d) Following the applicable Closing, TowerCo and each Sublessor Entity whose Sites were the subject of a Site Designation Supplement and whose Ground Lease or memorandum was not recorded, shall continue reasonable efforts to cause the Ground Lease or a memorandum thereof to be recorded. Such obligation shall expire on the first anniversary of the Final Closing. If any such Ground Lease or a memorandum is thereafter recorded in respect of any Site, the parties shall re-record the Site Designation Supplement for such Site. (e) Each Site Designation Supplement shall be in recordable form. TowerCo shall be responsible for effecting the recordation of all Site Designation Supplements, unless prohibited by Law or by the applicable Ground Lease, and TowerCo shall bear all costs and expenses incurred in connection therewith.

SECTION 5.12. Update of Information. (a) At all times prior to the Final Closing, each party shall promptly provide to the other party, subject to Section 4.6(b), with written notification of any material fact, event, occurrence or other information of any kind whatsoever which affects, or may affect, the truthfulness, correctness or completeness of any representation, warranty, covenant or agreement made in this Agreement, any other Transaction Document or any document, agreement, instrument, certificate or writing furnished to any party or its respective Affiliates pursuant to or in connection with this Agreement, or which affects or may affect the continued truthfulness, correctness or completeness of any thereof through the date of the Final Closing. Each such written notification shall specifically identify all representations, warranties, covenants and agreements affected by the fact, event, occurrence or information that necessitated the giving of the notice; provided, that, except as set forth in Section 4.6(b), no such notification of any material fact, event, occurrence or other information shall be deemed to modify, amend or supplement any such representation, warranty, covenant and agreement. 23 (b) Annex A sets forth, with respect to each Site listed thereon, among other things, the name of the Site, its useful life, the Ground Lease expiration date (if applicable) the Rent and Option Purchase Price Amount and denotes whether a Site has been completed or is under construction. The parties acknowledge that the information set forth in Annex A with respect to certain Sites is incomplete and may be updated from time to time to: (i) reflect additional information which becomes available, (ii) reflect completion of construction of a Site or (iii) reflect the substitution of Sites in accordance with Section 4.8 (each such Site, an "Incomplete Site"). SBCW represents that the Outside Expiration Date with respect to each Site equals (or, as to Incomplete Sites, will equal) not less than 75% or more than 80% of the remaining useful life of the Tower included in such Site, as such useful life has been determined by an independent appraiser retained by SBCW (the Parties acknowledging that SBCW is making no representation as to the accuracy of any such appraisal). Notwithstanding anything to the contrary contained in this Agreement, the Rent and Option Purchase Price Amount for any Incomplete Site shall be determined in accordance with the methodology used to determine the Rent and Option Purchase Price Amount in Annex A hereto. SECTION 5.13. TowerCo Parent's Guaranty. (a) TowerCo Parent unconditionally guarantees to SBCW, the Sublessor Entities, the SBCW Affiliates, and each SBCW Indemnitee (collectively, the "beneficiaries", individually a "beneficiary") the full and timely performance and observance of all of the terms, provisions, covenants and obligations of TowerCo under this Agreement and other Transaction Documents and any Affiliate of TowerCo under any Transaction Documents (the "Obligations"). TowerCo Parent agrees that if TowerCo or TowerCo's Affiliate defaults at any time in the performance of any of the Obligations, TowerCo Parent shall faithfully perform and fulfill all Obligations and shall pay to the applicable beneficiary all reasonable attorneys' fees, court costs, and other expenses, costs and disbursements incurred by the applicable beneficiary on account of any default by TowerCo or TowerCo's Affiliate and on account of the enforcement of this guaranty. (b) This guaranty obligation of TowerCo Parent shall be enforceable by the applicable beneficiary in an Action against TowerCo Parent without the necessity of any Action by such applicable beneficiary of any kind or nature whatsoever against TowerCo or its Affiliate, without the necessity of any notice to TowerCo Parent of TowerCo's or its Affiliate's default or breach under this Agreement or any Transaction Documents, and without the necessity of any other notice or demand to TowerCo Parent to which TowerCo Parent might otherwise be entitled, all of which notices TowerCo Parent hereby expressly waive. TowerCo Parent hereby agrees that the validity of this guaranty and the obligations of TowerCo Parent hereunder shall not be terminated, affected, diminished, or impaired by reason of the assertion or the failure to assert by the applicable beneficiary against TowerCo or its Affiliate any of the rights or remedies reserved to the applicable beneficiary pursuant to the provisions of this Agreement or any Transaction Documents or any other remedy or right which the applicable beneficiary may have at law or in equity or otherwise. (c) TowerCo Parent covenants and agrees that this guaranty is an absolute, unconditional, irrevocable and continuing guaranty. The liability of TowerCo Parent hereunder shall not be affected, modified, or diminished by reason of any modification or termination of this Agreement and any other Transaction Documents or any modification or waiver of or change in any of the covenants and terms of this Agreement or any Transaction Documents by agreement of the applicable beneficiary and TowerCo or its Affiliate, or by any unilateral action of either the applicable beneficiary or TowerCo or its Affiliate, or by an extension of time that may be granted by the applicable beneficiary to TowerCo or its Affiliate or any indulgence of any kind granted to TowerCo or its Affiliate, or any dealings or transactions occurring between the applicable beneficiary and TowerCo or its Affiliate, including, without limitation, any adjustment, compromise, settlement, accord and satisfaction, or release, or any bankruptcy, insolvency, reorganization, arrangement, assignment for the benefit of creditors, receivership, or trusteeship affecting TowerCo or its Affiliate. TowerCo Parent does hereby expressly waive any suretyship defense it may have by virtue of any Law of any state or Government. 24 (d) All of the applicable beneficiary's rights and remedies under this guaranty are intended to be distinct, separate, and cumulative and no such right and remedy herein is intended to be the exclusion of or a waiver of any other. (e) TowerCo Parent hereby waives presentment, demand for performance, notice of nonperformance, protest, notice of protest, notice of dishonor, and notice of acceptance. TowerCo Parent further waives any right to require that an action be brought against TowerCo or its Affiliate or any other person or to require that resort be had by the applicable beneficiary to any security held by the applicable beneficiary. The provisions of this Section 5.13 shall survive any termination of this Agreement. SECTION 5.14. Registration Statement. Within 20 days after signing this Agreement, TowerCo Parent agrees to file a registration statement on Form S-3 (or other appropriate form available for registering Parent Stock for sale to the public) and to use all reasonable efforts to have such registration statement declared effective before the expiration of thirty (30) days after the Initial Closing Date. If such registration statement has not been declared effective prior to the Initial Closing Date, then promptly after the Initial Closing, but in no event more than five (5) days after the Initial Closing Date, TowerCo Parent will add SBCW and each Affiliate receiving Stock Consideration under Section 3.2(b) to such registration statement to register the resale by them of up to $25,000,000 of Parent Stock issued to them at the Initial Closing pursuant to Section 3.2(b). If prior to the Initial Closing, such registration statement has been declared effective, then promptly after the Initial Closing, but in no event later than ten (10) days after the Initial Closing Date, TowerCo Parent will file a registration statement on Form S-3 (or other appropriate form available for registering Parent Stock for sale to the public) or amend an existing registration statement to register the resale by SBCW and each SBCW Affiliate receiving Stock Consideration under Section 3.2(b) of $25,000,000 of Parent Stock issued to them at the Initial Closing pursuant to Section 3.2(b) and will use all reasonable efforts to have such registration statement declared effective before the expiration of thirty (30) days after the Initial Closing Date. Notwithstanding the foregoing, TowerCo Parent may at any time elect to satisfy the obligation under this Section 5.14 by paying to SBCW and the SBCW Affiliates that would have received Parent Stock under Section 3.2(b) $25 million in cash in lieu of issuing to SBCW and such SBCW Affiliates $25 million of Parent Stock at the Initial Closing. The parties agree that any registration statement registering SBCW and any SBCW Affiliates resale of Parent Stock pursuant to this Section 5.14 will be treated as a registration statement under, and accordingly will be subject to the provisions of, the Registration Rights Agreement which will govern SBCW's and TowerCo Parent's obligations to each other in connection therewith. 25 SECTION 5.15. Parent Stock. (a) There shall be placed on all certificates representing shares of Parent Stock issued to SBCW and the SBCW Affiliates under Section 3.2 of this Agreement appropriate restrictive legends referencing the restrictions imposed by applicable Securities Law. TowerCo Parent shall cause such legend to be removed upon request of SBCW or such SBCW Affiliates, as applicable, pursuant to and as provided in Rule 144 of the Securities Act of 1933, as amended. SBCW and each SBCW Affiliate receiving Parent Stock under Section 3.2 represents and warrants that it is an "accredited investor" as defined in Rule 501(a) of the Securities Act and is acquiring the Parent Stock for its own account, not as a nominee or agent for any other person, and not with a view to, or in connection with, the sale or distribution thereof in violation of the securities laws of the United States of any state thereof..

The Master Lease will be on terms customary in the industry, including the following terms: (i) a five (5) year term; (ii) covering the antennas and related ground equipment (such ground equipment shall be located in the SBCW shelter, or on available ground space located outside the SBCW shelter not to exceed 12 square feet); (ii) terminable by Paging Tenant on ninety (90) days notice; (iii) rental rate of $600 per month per antenna with an annual rental increase of four percent (4%) per year; (iv) TowerCo may, in its discretion and at its cost, relocate such paging equipment on the Tower so long as it does not adversely effect in any material respect such Paging Tenant's use of such Site; (v) permitted use shall be to locate, maintain and operate the Paging Transmit System currently on the Tower together with the related equipment on the Site consistent with the then-current use by the Paging Tenant.

If the Indemnifying Party objects to any claim made by an Indemnified Party hereunder and the Indemnified Party initiates legal action with respect thereto, the Indemnifying Party agrees, to the extent it can do so, to join all affected parties in such action so that the rights and liabilities of the parties under this Agreement with respect to such claim may be resolved in one action. SECTION 13.5. Defense of Claims. (a) If any Action arises after the date hereof for which an Indemnifying Party may be liable under the terms of this Agreement, then the Indemnified Party shall notify the Indemnifying Party within a reasonable time after such Action arises and is known to the Indemnified Party, and shall give the Indemnifying Party a reasonable opportunity: (i) to conduct any proceedings or negotiations in connection therewith and necessary or appropriate to defend the Indemnified Party; (ii) to take all other required steps or proceedings to settle or defend any such Action; and (iii) to employ counsel to contest any such Action in the name of the Indemnified Party or otherwise. 45 (b) The expenses of all proceedings, contests or lawsuits with respect to such Actions shall be borne by the Indemnifying Party. If the Indemnifying Party wishes to assume the defense of such Action, then the Indemnifying Party shall give written notice to the Indemnified Party within thirty (30) days after notice from the Indemnified Party of such Action (unless the Action reasonably requires a response in less than thirty (30) days after the notice is given to the Indemnifying Party, in which event the Indemnifying Party shall notify the Indemnified Party at least ten days prior to such reasonably required response date), and the Indemnifying Party shall thereafter assume the defense of any such Action, through counsel reasonably satisfactory to the Indemnified Party; provided, that the Indemnified Party may participate in such defense at its own expense. The Indemnified Party shall have the right to control the defense of the Action unless and until the Indemnifying Party shall assume the defense of such Action. (c) If the Indemnifying Party does not assume the defense of, or if after so assuming the Indemnifying Party fails to defend, any such Action, then the Indemnified Party may defend against such Action in such manner as such Indemnified Party may deem appropriate (provided, that the Indemnifying Party may participate in such defense at its own expense); provided, however, that the Indemnified Party may not settle such Action without the Indemnifying Party's prior written consent, and the Indemnifying Party shall promptly reimburse the Indemnified Party for the amount of all expenses, legal and otherwise, reasonably and necessarily incurred by the Indemnified Party in connection with the defense against and settlement of such Action. If no settlement of such Action is made, the Indemnifying Party shall satisfy any judgment rendered in such Action, before the Indemnified Party is required to do so, and pay all expenses, legal or otherwise, reasonably and necessarily incurred by the Indemnified Party in the defense of such Action. (d) If an Order is rendered against the Indemnified Party in any Action covered by the indemnification hereunder, or any Lien in respect of such Order attaches to any of the assets of the Indemnified Party, the Indemnifying Party shall immediately upon such entry or attachment pay any amount required by such Order in full or discharge such Lien unless, at the expense and request of the Indemnifying Party, an appeal is taken under which the execution of the Order or satisfaction of the Lien is stayed. If and when a final Order is rendered in any such Action, the Indemnifying Party shall forthwith pay any amount required by such Order or discharge such Lien before the Indemnified Party is compelled to do so. SECTION 13.6. Certain Limitations. (a) Nothing in this Agreement shall be deemed to require any Sublessor Entity to indemnify any TowerCo Indemnitee for or in respect of any of the Real Estate Representations. Without limiting the generality of the foregoing, the sole remedies of TowerCo or TowerCo Parent in respect of a breach of any Real Estate Representation by any Sublessor Entity shall be to cause (i) such Sublessor Entity to continue to use reasonable efforts to cure such breach, as contemplated by Section 4.5, until the Final Closing Date, or (ii) the Site as to which such Real Estate Representation is breached to be, at the applicable Sublessor Entity's election, an Excluded Site or to defer the Closing of such Site to a later Closing Date, provided that the failure of any such deferred Site to become an Included Site on or prior to the Final Closing shall not constitute a default under this Agreement or give TowerCo Parent or TowerCo any remedy. 46 (b) Notwithstanding anything to the contrary contained herein, no Sublessor Entity shall have any obligation under this Section 13 to TowerCo Indemnitees with respect to the breach of representations, warranties, covenants or agreements by SBCW, unless, until and only to the extent that the aggregate of all TowerCo Indemnified Losses from all such breaches exceeds on a cumulative basis one percent (1%) of the aggregate amount of all Rent having been paid to SBCW or any other Sublessor Entity under the Sublease as of the date on which the claim for indemnification arose (the "Deductible Amount"), and then only to the extent of such excess amount. (c) Anything in this Agreement to the contrary notwithstanding, in no event shall any Sublessor Entity be liable under this Agreement for any indemnification obligation pursuant to this Section 13 in excess of 25% of the aggregate amount of the Rent having been paid to SBCW or such Sublessor Entity under the SBCW Sublease on account of the Site(s) owned by such Sublessor Entity as of the date on which the claim for indemnification arose (the "Maximum Indemnification"). SECTION 13.7. Limitation on Liability. In no event shall any party hereto or its respective Affiliates be liable to the other parties for any special, incidental or consequential damages suffered or incurred by such other parties to this Agreement or any third parties and caused by or arising out of any breach of any representation, warranty, covenant or agreement contained in this Agreement. SECTION 13.8. Survival. The representations and warranties of the parties contained in this Agreement shall survive any investigation before or after the date of this Agreement made by the other parties and the consummation of the transactions contemplated by this Agreement and shall continue in full force and effect for the periods specified below ("Survival Period"): (a) no representations and warranties of a Sublessor Entity relating to real estate matters, including without limitation Sections 6.6 through 6.13 shall survive the applicable Closing; and (b) all other representations and warranties in this Agreement shall be of no further force and effect after the first anniversary of the applicable Closing. Anything to the contrary notwithstanding, the Survival Period shall be extended automatically to include any time period necessary to resolve a claim for indemnification which was made before expiration of the Survival Period, but not resolved prior to its expiration, and any such extension shall apply only as to the claims asserted and not so resolved within the Survival Period. Liability for any such item shall continue until such claim shall have been finally settled, decided or adjudicated. 47 ARTICLE XIV TERMINATION SECTION 14.1. Termination for Certain Causes by SBCW. (a) This Agreement may be terminated at any time prior to the Final Closing by SBCW upon written notice to TowerCo, upon the occurrence of one or more of the following events, effective as of the date designated by SBCW in its notice of termination: (i) If any of the conditions set forth in Article XI (other than 11.4, 11.5, or 11.9) have not been satisfied, performed or waived in writing on or as of any applicable Closing Date; (ii) If an unwaived event of default shall have occurred and be continuing under Section 30(d) of the SBCW Sublease that would give SBCW the right to terminate the Sublease as to all Sites: provided, however that for the events listed in clause (i) above occurring after the Initial Closing, SBCW shall have the right to terminate this Agreement only if such event or events shall have or would have a substantial likelihood of preventing or delaying a Closing (it being understood that such prevention or delay may be caused by SBCW's exercise of its other rights under this Agreement in its reasonable discretion), such termination to be effective after notice to TowerCo and an opportunity for TowerCo to cure all such events within twenty (20) days of such notice. (b) If this Agreement is terminated by SBCW pursuant to Section 14.1(a), then SBCW shall be entitled to and TowerCo Parent shall pay SBCW, within five (5) business days following the date of such termination, a termination fee (the "Termination Fee") in the amount of four percent (4%) of the aggregate amount of Rent that would have been payable to SBCW and all Sublessor Entities under the SBCW Sublease as of the date of such termination. Upon any such termination, all Transaction Documents between the parties shall be terminated, and, at the option of SBCW, all prior Closings shall be rescinded. If SBCW exercises its option to rescind the prior Closings, payment of the Termination Fee shall be made by netting it against the amounts previously paid to Sublessor Entities at the previous Closings, and SBCW shall pay to TowerCo Parent any amounts paid to Sublessor Entities at the prior Closings which are in excess of the Termination Fee. (c) Notwithstanding the foregoing, SBCW shall not be entitled to terminate this Agreement pursuant to this Section 14.1 or receive a Termination Fee due to a breach, after the date hereof, of the representations and warranties provided in Sections 8.7 or 9.5 or for failure to satisfy the closing condition in Section 11.5 (it being understood that neither TowerCo or its Affiliates filed the litigation that causes the delay in Closing). SECTION 14.2. Termination for Passage of Time. This Agreement may be terminated by either party (i) if the Initial Closing shall not have occurred on or before the date which is four (4) months after the Effective Date through no fault of the terminating party, or (ii) if the conditions to Final Closing contained in Articles XI and XII shall not have been satisfied or waived through no fault of the terminating party in writing on or before the date which is eighteen (18) months after the Effective Date. With respect to Sites not included in a prior Closing hereunder, upon any such termination, no party shall have any further rights, Liabilities or obligations hereunder. 48 SECTION 14.3. TowerCo's Remedies. (a) Notwithstanding anything to the contrary contained herein, if the parties fail to consummate any Closing contemplated by the Closing Schedule as a result of SBCW's or SBCW's failure to keep, observe, perform, satisfy or comply with, fully and completely, any of the terms, covenants, conditions, agreements, requirements, restrictions or provisions required by this Agreement to be kept, observed, performed, satisfied or complied with by SBCW or SBCW, then TowerCo may exercise all such rights and remedies as may be provided for or allowed by law or in equity. Except as expressly set forth in the Transaction Documents, TowerCo Parent and TowerCo may, in addition to any other remedies that may be available at law or in equity, bring an action for specific performance, including attorneys' fees and costs of suit. (b) Each Sublessor Entity hereby acknowledges and agrees that in the event of such Sublessor Entity's default hereunder, TowerCo shall be entitled to, without limitation, (i) an Action for specific performance against such Sublessor Entity and (b) the right to seek, prove and recover direct damages from such Sublessor Entity incurred by TowerCo in connection with such Action, including without limitation, court costs and attorneys' fees in connection with such Action. ARTICLE XV RIGHT OF FIRST OFFER Following the date of the Final Closing and so long as the Build-to-Suit Agreement remains in effect, neither SBCW or any Sublessor Entity may assign, transfer, sell, lease or dispose of all or substantially all of its right, title or interest in or to an Excluded Site except for assignments, transfers or sales (A) to an SBCW Affiliate, (B) to a successor entity in connection with the merger, consolidation or other reorganization of SBCW or such Sublessor Entity, (C) in connection with the sale or other transfer or all or a portion of SBCW's wireless business on a Site by Site basis, or (D) in accordance with the following pre-emption procedures: (a) SBCW must first offer such Excluded Sites to TowerCo by providing a written notice to TowerCo (i) stating that SBCW intends to transfer, lease, sell or otherwise dispose of such Excluded Sites, (ii) the number and location of all Excluded Sites subject to the proposed transfer, lease or sale and (iii) the specified purchase price or other consideration to be paid to SBCW in connection with such transfer, lease or sale (the "SBCW Economic Offer"). TowerCo shall have ten (10) days after receipt of the SBCW Economic Offer (the "Notice Period") to elect to purchase or lease the Excluded Sites on the terms of the Economic Offer. A failure by TowerCo to respond in writing to SBCW prior to the end of the Notice Period shall be deemed to be a rejection by TowerCo of the offer for the Excluded Sites. TowerCo may elect to purchase or lease the Excluded Towers on the terms of the SBCW Economic Offer by delivering written notice ("Acceptance Notice") to SBCW prior to the end of the Notice Period. 49 (b) If TowerCo delivers an Acceptance Notice, the closing of the transfer or lease of such Excluded Sites to TowerCo shall be held within 60 days after the date on which the Acceptance Notice is delivered. If an Acceptance Notice is not delivered by TowerCo prior to the end of the Notice Period, or TowerCo fails to close the purchase or lease of the Excluded Sites on the closing date specified in the prior sentence, SBCW shall be free to transfer or lease such Excluded Sites to a third party on the terms no more favorable to such third party than those provided in the SBCW Economic Offer within 180 days after the end of the Notice Period; provided, however, that if the offer made to such third party is more favorable to such third party than that provided in the SBCW Economic Offer, SBCW or the applicable Sublessor Entity shall offer such Excluded Sites to TowerCo on the new economic terms prior to the transfer or lease of such Excluded Site to a third party in accordance with the provisions of this Article XV. (c) If such Excluded Sites have not been so transferred to a third party within such 180 day period, then the restrictions provided in this Article XV shall again apply with respect to such Excluded Sites, and SBCW shall have no right to transfer or sell any such Excluded Sites without again offering such Excluded Sites to TowerCo in accordance with the provisions of this Article XV. ARTICLE XVI GENERAL PROVISIONS SECTION 16.1. Notices.

If any term of this Agreement, or part thereof, not essential to the commercial purpose of this Agreement is held to be illegal, invalid or unenforceable by a Forum of competent jurisdiction, it is the intention of the parties that the remaining terms hereof, or part thereof, constitute their agreement with respect to the subject matter hereof and all such remaining terms, or parts thereof, remain in full force and effect.

The parties acknowledge that all Constructed Improvements developed and constructed by SBCW or Vendor on any BTS Site are intended to constitute a part of SBCW's Improvements, and are not intended to be shared by Space Subtenants or constitute a part of the Improvements. The parties further acknowledge that Improvements, other than Constructed Improvements, do not constitute a part of SBCW's Improvements. Any Affiliate of SBCW operating a mobile cellular telephone business that is integrated with SBCW's and its other Affiliates' current cellular telecommunications business in the Territory shall be deemed a SBCW Party for purposes of this Section 3.01 and Section 3.10; provided, however, that the engagement of Vendor pursuant to this Section 3.01 and the exclusive rights provided to Vendor pursuant to Section 3.10(a) shall only apply to SBCW and the SBCW Parties set forth on the signature pages to this Agreement, and their respective successors and assigns (but only if and for so long as such successors or assigns are Affiliates of SBC Communications Inc.). Vendor hereby accepts such engagement in accordance with the terms and conditions of this Agreement. Vendor shall construct the Tower and Improvements at each BTS Site in accordance with the Implementation Plan and applicable Site Schedule. Vendor shall perform and be responsible for all responsibilities assigned to Vendor in the Vendor Responsibility Matrix attached hereto as Annex B. In addition to the engagement provided for in this Section 3.01, Vendor acknowledges and agrees that SBCW may engage Vendor on behalf of any Affiliate of SBCW or of the SBCW Parties (e.g., Bell South wireless companies) to develop and construct up to a maximum of one hundred (100) Towers and Improvements on BTS Sites located within the Territory and to perform the Services as required under this Agreement for such Towers, and such engagement shall not be limited by the limitation set forth in the fourth (4th) sentence of in this Section 3.01(a). Upon completion of such Towers, the applicable Affiliate of the SBCW Parties shall occupy the Leased Space subject to the terms of the BTS Sublease. 9 (b) Subject to Section 3.02(b), Vendor's compensation for Completion of the Work on BTS Sites pursuant to this Agreement and performance of the Services, or any part thereof, will be derived solely from the payment of the BTS Rent by SBCW pursuant to the BTS Sublease (notwithstanding that such BTS Rent may be paid to an Affiliate of Vendor). The parties agree that the BTS Rent payable by SBCW to Vendor with respect to the Leased Space of any Completed BTS Site or TowerCo Existing Site shall be $1400 per month subject to an annual increase as provided in Section __ of the BTS Sublease [As described on Exhibit J]. This Section 3.01(b) shall survive any expiration or termination of this Agreement. Section 3.02. Identification of Collocation Sites. (a) Vendor may, without delaying any of its obligations under this Agreement, including, without limitation, its obligations pursuant to Article 5, at any time during the Term, provide SBCW with a written notice proposing any TowerCo Existing Site within a search area specified in the applicable SARF that would be suitable for the collocation of SBCW's Communications Equipment ("Potential Collocation Sites"). SBCW shall either accept the proposed site, or at SBCW's option, in the event that SBCW reasonably believes that such site does not satisfy the minimum standards set forth in Annex M, reject such site by sending notice of such election in writing to Vendor within fifteen (15) days after the notice thereof. In addition, SBCW may reject a Potential Collocation Site in writing within fifteen (15) days after SBCW's receipt of Vendor's notice thereof if there then exists an alternative site within such search area that, in SBCW's judgment, is also suitable for the collocation of SBCW's Communications Equipment but that is available to SBCW upon economic terms and conditions that are, in SBCW's judgment, more favorable to SBCW. In the event SBCW pursues a Potential Collocation Site, Vendor shall provide SBCW with Compliance Data, a Site Data Package and a Due Diligence Package with respect to such site within fifteen (15) days after receipt of SBCW's notice. If SBCW elects to become a tenant on a TowerCo Existing Site, Vendor shall sublease the Leased Space thereon to SBCW or its Affiliate pursuant to the BTS Sublease and SBCW and Vendor shall execute a Site Designation Supplement for such TowerCo Existing Site. If SBCW rejects a Potential Collocation Site as provided above in the event there exists a suitable alternative site within the applicable search area, Vendor shall have no further obligation with respect to that Potential Collocation Site and SBCW shall be entitled to pursue such alternative site without reference to this Agreement. Furthermore, if SBCW rejects or does not pursue a Potential Collocation Site, Vendor shall keep performing all of its obligations hereunder, including, without limitation, performing search Services in such search area as provided in Article 5. (b) If SBCW is interested in a Potential Collocation Site, Vendor may, upon written notice thereof to SBCW, offer the performance of certain other Collocation Services set forth in Annex I (the "Collocation Services") with respect to such Potential Collocation Site; provided, that Vendor acknowledges that at any time during the Term, SBCW shall have the right to engage any Person other than Vendor to perform such Collocation Services. If the terms, conditions and fees in connection with such Collocation Services are acceptable to SBCW, SBCW may engage Vendor to perform such Collocation Services upon written notice to Vendor within five (5) Business Days after receipt by SBCW of the offer from Vendor. If SBCW elects to engage Vendor to perform such Collocation Services pursuant to this Section 3.02(b), such Collocation Services shall be performed in compliance with the requirements of this Agreement, including, without limitation, compliance with quality standards, Governmental Requirements, Permits and Environmental Laws, in each case as applicable to such Collocation Services. Vendor hereby acknowledges and agrees that any and all fees in connection with performance of any Collocation Services shall be due and payable only if SBCW installs its Communications Equipment on a Potential Collocation Site. 10 Section 3.03. Term. (a) Subject to Article 13, this Agreement shall commence on the Effective Date, and shall continue until the fifth (5th) anniversary of the Effective Date (the "Term"), plus such additional time as may be required (i) for an aggregate number of new Towers to be developed and Completed by either Vendor or SBCW (either itself or through a third party pursuant to Section 3.10(c)) equal to the number of Towers that SBCW elected, pursuant to Section 3.10(d), to become "Substitute Sites" under the Agreement to Sublease and (ii) for the parties to satisfy their respective obligations hereunder to the extent such obligations arose or accrued prior to such fifth (5th) anniversary. (b) Notwithstanding anything to the contrary contained herein, the parties acknowledge and agree that upon Completion of any BTS Site and execution of a Site Designation Supplement therefor or the execution of a Site Designation Supplement with respect to any TowerCo Existing Site, except with respect to those provisions of this Agreement which survive the expiration or termination hereof, the BTS Sublease, the applicable Site Designation Supplement and related documents shall govern the respective rights and obligations of the parties with respect to such BTS Site or TowerCo Existing Site. Section 3.04. Time for Commencement and Completion. Vendor and SBCW acknowledge that the time for Scheduled Commencement Date and Completion of the BTS Site will be determined by the applicable Implementation Plan and the Site Schedule. Vendor's unexcused failure to Complete any BTS Site in accordance therewith shall subject Vendor to the Liquidated Damages pursuant to Section 11.01. Section 3.05. Relationship. Vendor agrees to furnish its best skill and judgment in performing its obligations hereunder, and to cooperate with SBCW in furthering SBCW's interests. Except as expressly provided in Section 8.01, SBCW, Vendor and TowerCo Parent, in the performance of this Agreement will be acting in their individual capacities and not as employees, partners, joint venturers, agents or associates of one another. In the performance of this Agreement, Vendor is, and shall at all times during the term of this Agreement be, an independent contractor. Nothing contained in this Agreement creates the relationship of a joint venture, partnership, association or agency between the parties. No party shall have any authority to bind or otherwise obligate the other. Persons retained by either party as employees or agents shall not, solely by reason thereof, be deemed to be employees or agents of the other party. 11 Section 3.06. Project Personnel. (a) Vendor shall, at its own cost and expense, employ only competent and able personnel for the performance of the Services and all of Vendor's obligations under this Agreement, including, without limitation, contractors and subcontractors that are properly licensed and legally qualified to construct the Towers and Improvements and complete the Work on each BTS Site and/or provide the Collocation Services. Vendor shall make available to SBCW a list of its principal contractors and subcontractors, and SBCW shall have the right to request a particular contractor or subcontractor be removed from the list for the Project so long as such request is based upon commercially reasonable criteria. Vendor shall, at all times during the term of this Agreement, keep a sufficient number of qualified personnel to the extent required to Complete the Project pursuant to the Implementation Plan and Site Schedules, including without limitation, a sufficient number of suitable experts in the areas of engineering, design, construction, installation, management, performance enhancement and other operational specialties applicable to the Project.

(b) If reasonably requested by SBCW, Vendor shall make available additional suitable experts in the areas of engineering, design, construction, installation, management, performance enhancement and other operational specialties applicable to the Project, and SBCW shall pay any direct costs associated with any such suitable experts that are in addition to those required pursuant to Section 3.06(a). (c) Vendor will be solely responsible for the actions and conduct of all its employees, agents, consultants, advisors, contractors and subcontractors. Vendor will ensure that anything related to its employees, agents, consultants, advisors, contractors or subcontractors shall be in strict compliance with Governmental Requirements. (d) SBCW reserves the right to require Vendor to immediately remove and exclude any Person or entity employed by or otherwise working for Vendor, its agents, consultants, contractors, subcontractors or advisors, from any BTS Site or TowerCo Existing Site, at SBCW's reasonable discretion, who (i) engages in any misconduct, (ii) is incompetent or (iii) is negligent in the performance of its, his or her duties. Vendor shall be responsible for any additional labor costs arising in connection with any removal or exclusion requested pursuant to this Section 3.06(d). (e) Vendor shall assign key managers and personnel, including Contract Managers as provided below, to manage, supervise and be responsible for the timely performance of Vendor's obligations hereunder. Unless SBCW otherwise consents in writing, as to each BTS Site, Vendor shall (i) allocate sufficient personnel to devote time and attention to such BTS Site, and (ii) not remove any key manager (including Contract Managers) from any such position or reassign any such key manager, either within the Project or to another project, without a qualified replacement. In addition, each party agrees to assign to the Project contract managers (the "Contract Managers") to provide overall supervision and management of the Project. Each party may change its Contract Managers at any time and from time to time. The parties further agree to cooperate with each other in implementing the due diligence and construction process set forth in this Agreement in order to Complete the Work on all BTS Site pursuant to the terms of this Agreement and to use their commercially reasonable efforts to amicably resolve any and all issues relating to performance by each party of its respective rights and obligations hereunder. The foregoing is intended to set forth a general approach to the day-to-day conduct of the Project, but is not intended to qualify or limit the obligations of the parties hereunder or any rights hereunder that any party may have in respect of a breach by the other party of such obligations. 12 Section 3.07. Familiarity with Project and BTS Sites. Vendor represents and warrants that Vendor is familiar with projects similar to the Project, is or will become familiar with the Specifications applicable to the Towers and Improvements, will visit and examine each BTS Site and the surrounding locale, and knows or will know the working conditions in and around each BTS Site. Section 3.08. Quality Standard. Vendor agrees to perform its obligations and furnish its Services hereunder properly, diligently, and in good faith, in accordance with the standards of its profession, and in accordance with all applicable Governmental Requirements. Vendor shall implement quality control procedures, which shall be sufficient to ensure compliance with the Specifications and shall otherwise maintain quality standards for the Services at least equal to the normal quality standards applied by Vendor and entities Controlled by TowerCo Parent prior to the date of this Agreement. Section 3.09. Books and Records of Vendor, Right of Inspection by SBCW. Vendor shall keep such accounts as may be necessary for its proper financial management of the Project under this Agreement. The system of accounting employed by Vendor shall be such as is reasonably satisfactory to SBCW. SBCW shall be afforded access to all of Vendor's records, books, correspondence, instructions, drawings, plans, blueprints, specifications, receipts, vouchers, memoranda and similar data relating to the Project and this Agreement to the extent relating to SBCW's intended use, Vendor's compliance with the terms hereof, Vendor's and each BTS Site's and TowerCo Existing Site's compliance with Governmental Requirements, the structural integrity of the Improvements, or if SBCW otherwise provides reasonable justification therefor, except for privileged documents or where disclosure is prohibited by law. Such books and records shall be open for inspection and copying upon reasonable written notice by SBCW, at its cost, and its authorized representatives at reasonable hours at Vendor's principal office and shall be retained by Vendor for a period of three (3) years after the expiration of the BTS Sublease. Section 3.10. Scope of the Project. (a) Subject to the terms and conditions of this Agreement, SBCW, for itself and as agent for the SBCW Parties, hereby grants to Vendor for the Term the exclusive right to develop new Towers which SBCW elects to have constructed in the Territory; provided that the foregoing shall not apply with respect to Sites subject to the existing contracts listed in Part A of Annex N annexed hereto (the "Existing Contracts") and the "in-progress" Sites listed in Part B of Annex N. The exclusive rights provided to Vendor hereunder shall only apply to SBCW and the SBCW Parties set forth on the signature pages to this Agreement, and their respective successors and assigns (but only if and for so long as such successors or assigns are Affiliates of SBC Communications Inc.) (b) Notwithstanding anything to the contrary contained herein and subject to Article 13, the parties agree that during the Term, Vendor shall have the exclusive right and obligation to perform all Services on the BTS Sites pursuant to this Agreement other than Collocation Services and except as expressly provided in this Agreement to the contrary, and shall have an affirmative obligation to Complete the Work on any such BTS Sites in strict compliance with the provisions of this Agreement; provided, however, that if at any time during the Term, Vendor's right and obligation to perform Services on the BTS Sites is suspended or terminates (i) in respect of any BTS Site pursuant to Section 13.01(b)(i), then SBCW shall have the right to engage any Person to perform any and all Services on such BTS Site, or (ii) pursuant to Section 13.01(b)(ii), then SBCW shall have the right to engage any Person to perform any and all Services on any or all BTS Sites. SBCW reserves the right to construct and install all of the Constructed Improvements and its Communications Equipment on the BTS Sites; provided, however, that SBCW shall have the right to request that Vendor construct and install one or more concrete equipment pads or raised platforms capable of accommodating SBCW's or SBCW Party's buildings, huts or equipment shelters. SBCW agrees to negotiate in good faith with Vendor for Vendor to construct and install SBCW's Communications Equipment. 13 (c) Notwithstanding anything to the contrary contained herein, SBCW reserves the right, either directly or through a SBCW Party or any third party, to acquire Sites and thereafter to develop and construct its own Towers pursuant to the terms summarized on Schedule 3.10(c) hereof. Following Completion of such Towers, such Towers shall be sold to Vendor (or to Southern Towers, Inc., an Affiliate of Vendor) for an amount calculated in accordance with the schedule of costs agreed to by the parties and attached to Schedule 3.10(c). After the sale of any such Tower to Vendor (or Southern Towers, Inc.), said Tower shall be deemed to be a BTS Site and SBCW or a SBCW Party shall occupy the Leased Space subject to the terms of the BTS Sublease. In acquiring, developing and constructing its own Towers as aforesaid, SBCW or the applicable SBCW Party may retain one or more third party consultants and/or contractors to perform the work associated therewith, but the retaining of such entities shall not otherwise relieve SBCW from its obligations under this Agreement. The obligation of SBCW to sell Towers that it has developed to Vendor (or Southern Towers, Inc.) shall not apply to (i) Sites controlled by SBCW or SBCW Parties with respect to which, as of the date of the Agreement to Sublease, actual construction has commenced, defined as the issuance of building permits for such Site, or (ii) the "in-progress" Sites listed in Part B of Annex N. (d) At any time on or before the "Final Closing Date" under the Agreement to Sublease, SBCW may elect to have any Towers that are being developed by either Vendor or by SBCW (either itself or through a third party pursuant to Section 3.10(c)) become "Substitute Sites" pursuant to the Agreement to Sublease rather than become BTS Sites under this Agreement and the BTS Sublease. For such Tower to so become a Substitute Site, such Tower must satisfy all of the conditions and criteria set forth in the Agreement to Sublease for Substitute Sites and, in addition: (i) if such Tower is being developed by Vendor, no later than thirty (30) days before the anticipated date of Completion of such Tower, Vendor shall provide to SBCW Vendor's reasonable good faith estimate of (A) Vendor's actual, direct out-of-pocket costs of acquiring the applicable Site and developing and constructing such Tower (including all Site acquisition costs and other "hard" and "soft" costs), plus ---- (B) Vendor's personnel and related costs reasonably allocated to such Tower based on the amount spent by such personnel on such Site acquisition and development and construction, and, if SBCW shall elect to have such Tower become a Substitute Site (which election shall be made in writing no later than fifteen (15) days after receipt of Vendor's calculation), upon Completion of such Tower, SBCW shall acquire such Tower from Vendor for an amount equal to the actual amounts under (A) plus (B) above (calculated as of ---- the Completion date), plus (C) a profit margin equal to Vendor's customary profit margin for arms-length ---- agreements to develop Towers for third parties. Following the acquisition of such Tower by SBCW, such Tower shall be leased to Vendor's Affiliate, Southern Towers, Inc. pursuant to the Agreement to Sublease and shall be governed by the Agreement to Sublease and the SBCW Sublease rather than by this Agreement; and (ii) if such Tower is being developed by SBCW (either itself or through a third party pursuant to Section 3.10(c)), and if SBCW shall elect to have such Tower become a Substitute Site (which election shall be made in writing no later than fifteen (15) days before the anticipated date of Completion of such Tower), then upon Completion, such Tower shall be leased to Vendor's Affiliate, Southern Towers, Inc. pursuant to the Agreement to Sublease and shall be governed by the Agreement to Sublease and the SBCW Sublease rather than by this Agreement. Transaction and transfer costs associated with a Tower becoming a "Substitute Site" as set forth in this Section 3.10(d) shall be governed by paragraph 7 of Schedule 3.10(c). 14 Section 3.11. Available BTS Sites in Event of Condemnation. If prior to the execution of a Site Designation Supplement for a BTS Site, any condemnation occurs as to any BTS Site so as to render such BTS Site unsuitable for the Permitted Use, Vendor shall, at the request of SBCW, perform all its obligations hereunder in respect of a replacement site for such condemned BTS Site satisfactory to SBCW consistent with the requirements of Article 5, as if such replacement site were a BTS Site hereunder, including without limitation, Acquisition of such replacement site, the construction of a Tower and Improvements on any selected BTS Site pursuant to and in accordance with Article 6 and the further subleasing of a portion of such BTS Site to SBCW or its Affiliate pursuant to the BTS Sublease and a Site Designation Supplement. The monthly amounts payable in respect of such replacement BTS Site shall be equal to the amount of the BTS Rent that would have been payable in respect of the replaced condemned BTS Site. The Site Schedule, Scheduled Commencement Date and Completion Date for any such replacement site shall be determined by Vendor and SBCW consistently with the construction schedules applicable to BTS Sites in general. This Agreement shall survive the Term indefinitely to the extent necessary to give effect to this Section 3.11. Article IV Vendor's Undertakings. Section 4.01. Vendor's Undertakings. (a) Commencing on the Effective Date of this Agreement, Vendor agrees to furnish the Services for and on behalf of SBCW and to perform such Services in an expeditious manner consistent with the interests of SBCW. In the performance of the Services, Vendor shall furnish its best skill and judgment (i) in accordance with the standards established by the industry, (ii) consistent with good development and construction practices and efficient business practices, (iii) utilizing skill and judgment available throughout its organization in the performance of this Agreement to provide its professional knowledge, ideas, experience and abilities relating to the design, scheduling, development and construction of the Towers and Improvements, and (iv) in a competent, professional and efficient manner. (b) Vendor shall keep SBCW fully informed of all Governmental Requirements that affect, in any material respect, the Services to be performed hereunder and shall promptly notify in writing SBCW of any part of the Project that does not comply with any Governmental Requirements to the extent Vendor is or becomes aware of such noncompliance. (c) In addition to the Services, as described in this Agreement, Vendor shall have such other duties and responsibilities reasonably and customarily required for developments similar to the development of each BTS Site as may be required or necessary from time to time during the design, development, construction, equipping and Completion of each BTS Site, which other duties and responsibilities shall be deemed to be within the scope of this Agreement; provided, however, that SBCW shall not incur any costs or expenses for or in connection with any such services for BTS Sites. Section 4.02. Governmental Requirements and Permits. (a) Vendor shall obtain, or cause to be obtained, the consent or approval of all Governmental Authorities. and all Permits necessary for the Development of each BTS Site. Vendor shall advise SBCW in writing of any potential issues or problems, including without limitation any delays in connection with obtaining any approvals from Governmental Authority. (b) Vendor shall coordinate and manage all professional and technical services required in connection with the preparation and filing of applications for and obtaining all Permits Vendor shall be responsible for diligently preparing and filing all applications for, and pursuing and obtaining, the Permits. (c) Permits will be filed by Vendor in its own name, except where prohibited by applicable laws, and SBCW shall assist Vendor in securing all such Permits. 15 (d) Vendor shall use its best efforts to obtain any Permits necessary to commence construction of the Tower and Improvements on or before the Scheduled Commencement Date with respect to each BTS Site, and shall, unless otherwise set forth in the Site Schedule, prepare and file an application for the required Permit or Permits with the applicable Governmental Authority not later than thirty (30) days after the date of the applicable Notice to Proceed. Vendor's efforts relating to obtaining any Permits shall include, without limitation, the approval of any necessary rezoning of such BTS Site, grant of any variance, vacating of any right-of-way, issuance of any order or other action that may be necessary, or approve any other land use approval necessary, to commence construction of the Tower and Improvements on such BTS Site. If, despite such efforts, any Permits required to be obtained before commencement of construction have not been obtained or could not have been obtained as of the Scheduled Commencement Date, then Vendor shall continue, if SBCW agrees, to exercise its best efforts, for a period of at least one (1) year, to obtain any such Permits as promptly as possible, and, subject to Section 4.02(e), the Scheduled Commencement Date will be adjusted to reflect all additional time which will be required for the performance of any of the duties or obligations of Vendor under this Agreement as a result of the delay in obtaining the Permits. The failure to obtain any such Permit shall not in and of itself constitute a breach of Vendor's obligations hereunder. However, the failure of Vendor to perform any of its obligations set forth in this Section 4.02 shall constitute a breach of Vendor's obligations under this Agreement, which, if not cured as contemplated by Section 13.01(a)(i), would constitute an event of default hereunder. (e) If Vendor has not obtained any Permit required for the Construction of the Tower and Improvements on any BTS Site, or for the Permitted Use thereof or any other required Permit by the applicable Scheduled Commencement Date set forth in the applicable Site Schedule, but in no event later than ninety (90) days after SBCW issues a Notice to Proceed for any BTS Site, then, at any time thereafter, SBCW will have the right, at SBCW's sole option, to (i) assume responsibility for obtaining such Permit by written notice to Vendor, and Vendor shall reimburse SBCW for any costs, fees, or expenses (including reasonable attorneys' fees and expenses) incurred in pursuing and obtaining such Permit; provided, however, that any reimbursement in excess of $20,000 shall be subject to Vendor's pre-approval; provided, further, however, that if Vendor fails to approve any reimbursement in excess of $20,000, then SBCW shall have the right to pursue obtaining such Permits and shall be liable for any costs, fees and expenses incurred in connection therewith in excess of $20,000, and provided, further, however, that any election under this clause (i) shall be without prejudice to SBCW's right to elect later one of the options set forth in clause (ii) or (iii) below with respect to such BTS Site; (ii) reject the BTS Site at no cost or expense to SBCW, whereupon SBCW shall have the right to engage any Person to perform Services in respect to such BTS Site or an alternative site within the applicable SARF; or (iii) reject the BTS Site and cause Vendor to propose additional potential cell sites as alternatives, in accordance with Section 5.01. If SBCW makes the election in clause (ii) above and shall, either itself or through a third party, acquire a site and develop a tower within the applicable SARF, then the provisions of Section 3.10(c) hereof shall govern the acquisition of such site, the development of such tower and the sale of such tower to Vendor. 16 (f) Vendor shall comply with all Governmental Requirements in performing its obligations under this Agreement, the BTS Sublease and each Site Designation Supplement. Vendor shall indemnify, and hold harmless, each SBCW Indemnitee from and against any Claims (including without limitation any fine, penalty or damage) arising out of Vendor's failure to comply with any Governmental Requirements including, without limitation, zoning laws and FAA and FCC regulations. (g) If SBCW determines that Vendor's proposed Tower height would cause an extension of time to obtain any Permit beyond the period set forth in the applicable Site Schedule, Vendor shall, at SBCW's written request, revise the Due Diligence Package to provide a Tower height which, while meeting SBCW's requirements, will, in SBCW's judgment, be permitted in a timely fashion consistent with the applicable Site Schedule; provided, however, that in revising the Due Diligence Package, Vendor shall have the right to pursue (i) Permits for a Tower which meets SBCW's requirements but which can be subsequently modified to increase the height of the Tower in order to meet Vendor's requirements and/or (ii) simultaneous Permits for the construction of (1) a temporary structure which satisfies SBCW's requirements, if all Permits for such temporary structure can be obtained within the time provided in the applicable Site Schedule, and (2) a permanent Tower with greater height which meets both SBCW's and Vendors requirements. In the event that SBCW installs its Communications Equipment on any temporary tower structure prior to Vendor's completion of obtaining permits and constructing a higher permanent Tower, following completion of such higher permanent Tower, SBCW's Communications Equipment shall be relocated to the permanent Tower at Vendor's sole cost and expense, and under the direction of SBCW (h) Notwithstanding anything to the contrary contained herein, Vendor may, but shall not be required to file or pursue any appeal or other similar action to be filed with a court of competent jurisdiction ("Permit Appeal Action") in connection with obtaining Permits; provided, however, that Vendor shall not pursue a Permit Appeal Action that in any way involves SBCW or uses SBCW's name or represents any interest of SBCW absent prior consultation with SBCW and express written consent from SBCW to take such Permit Appeal Action. Vendor shall notify SBCW if Vendor desires to initiate Permit Appeal Action with respect to any BTS Site and, following the giving of such notice, SBCW shall promptly respond in writing whether it has any objection to Vendor initiating such Permit Appeal Action. If SBCW shall so object, then SBCW shall no longer be obligated under Section 3.10 to exclusively engage Vendor to perform the Services on such BTS Site and SBCW shall be free to engage any Person to construct Tower, Improvements and Constructed Improvements on such BTS Site and perform any Services in connection therewith. 17 Article V Pre-Construction Phase Section 5.01. Proposal of BTS Sites; Development Plan. (a) From time to time during the Term in connection with SBCW's need for a new Tower, SBCW shall issue a search area request form ("SARF") to Vendor pursuant to Attachment A to Annex C attached hereto. Promptly after receipt of each SARF, but in no event later than thirty (30) days after the giving of such notice, Vendor shall perform searching services in the search area designated in such SARF by using diligent, good faith efforts, consistent with the standards set forth in Section 4.01, to identify at least three (3) potential BTS Site locations, unless otherwise agreed, within each radio frequency search area identified in such SARF and to prepare a preliminary Site Schedule and a Site Data Package collecting the information set forth in Annex G-1 attached hereto, to the extent required by SBCW prior to issuance of the Notice to Proceed for presenting such potential sites to SBCW for final selection. No site shall be proposed (or shall be required to be proposed) unless Vendor reasonably believes that such site meets the requirements for proposed BTS Sites set forth in Annex L to this Agreement (the "Minimum Standards for BTS Sites") of this Agreement for BTS Site in all material respects and that it will be possible, with the exercise of diligent efforts, to obtain the Permits necessary to construct the Tower and Improvements. Within fifteen (15) days after receipt of Vendor's proposal, SBCW shall in writing either accept or, if SBCW reasonably believes that such sites do not satisfy the Minimum Standards for BTS Sites, reject one or more of the proposed BTS Sites and, in the event SBCW accepts such proposed site, such site shall become a BTS Site. If none of the sites proposed by Vendor for any search area are accepted by SBCW, Vendor shall have an additional thirty (30) days in which to propose additional potential BTS Sites. SBCW shall accept one or more of the additional proposed BTS Sites or, at SBCW's option, in the event that SBCW reasonably believes that such sites do not satisfy the Minimum Standards for BTS Sites, reject the proposed BTS Sites in writing within fifteen (15) days after receipts of Vendor's proposal. If SBCW shall accept more than one proposed BTS Site or additional proposed BTS Site, then Vendor may, in its reasonable judgment, select one such Site and pursue that Site rather than the others accepted by SBCW. If none of the proposed BTS Sites are accepted by SBCW or if Vendor is unable, notwithstanding diligent efforts, to propose a site that meets the requirements of this Section 5.01 within the time period set forth herein, Vendor shall have no further obligation to search for potential sites in response to such SARF, and SBCW shall be entitled to pursue such site without reference to this Agreement. (b) Vendor will provide SBCW with methodology for each search ring and keep logs demonstrating reasons for rejecting potential BTS Sites, including why viable alternative locations were rejected. SBCW has the right to inspect these logs upon reasonable notice. 18 (c) SBCW's right to select any proposed BTS Site as a BTS Site shall not relieve or release Vendor from performing any of its obligations hereunder in respect of such BTS Site or otherwise affect any of Vendor's obligations hereunder. Together with SBCW's written notice of the acceptance of a proposed site as a BTS Site, SBCW shall deliver to Vendor a Notice to Proceed with respect such BTS Site in the form of Annex D attached hereto, to be completed and returned to SBCW in accordance with Section 5.02. Acceptance of the proposed BTS Site does not constitute final acceptance of the construction which shall be governed by Section 6.12 hereof. (d) Not later than ten (10) days after receipt of the Notice to Proceed as to any BTS Site, Vendor shall prepare for the Development of each BTS Site and shall submit to SBCW for its approval, which approval shall not be unreasonably withheld or delayed, an Implementation Plan and a final Site Schedule with respect to such BTS Site, which shall include, among other things, design services, preparation of a development plan, and coordination of construction activities. Section 5.02.

Included in the information provided by Vendor to SBCW shall be an estimate of when the equipment shelter can be placed and when the equipment can be activated. In addition, SBCW may request and Vendor shall facilitate progress meetings with Vendor's key managers and subcontractors, including the establishment of oversight committees to monitor specific work in progress on BTS Sites at times and locations agreed upon by SBCW and Vendor in writing no less than seven (7) days prior to such meetings. Progress reports shall be for planning purposes and monitoring compliance with this Agreement. (b) Should any information or approval be required from SBCW as Work progresses, Vendor shall request such information or approval in writing. Said requests shall be submitted sufficiently in advance of the date upon which the information or approval is needed, but in no event less than five (5) days in advance of such date, to permit SBCW to act without affecting the progress or sequence of the Work. Such request shall provide a reasonable time for a response by SBCW. (c) Vendor shall, on a periodic basis (but not less frequently than weekly), review the progress of the construction, evaluate the percentage of completion of each BTS Site as indicated in the Implementation Plan and the applicable Site Schedule. The construction schedule report shall be distributed not less than weekly during the construction phase of the Project indicating the actual progress compared to the scheduled progress of the Work in accordance with the applicable Site Schedule. The reports shall compare the actual construction dates to scheduled construction dates for each BTS Site. 20 (d) Following completion of the Tower and Improvements, Vendor has five (5) Business Days in which to provide Completion Data to SBCW. Upon acceptance of the Completion Data, SBCW shall, within five (5) Business days of receipt of the Completion Data, either issue approval of this Completion Data or provide a written explanation of the deficiency if SBCW does not accept the Completion Data. Section 6.02. Performance of the Work Vendor shall have the responsibility and obligation to perform the Work in accordance with Annex A. Vendor shall provide a management team or a representative on each BTS Site to provide supervision and administration of the Completion of the Work for each such BTS Site. Vendor shall establish and implement coordination and communication procedures between Vendor and SBCW.

Section 6.03. Implementation Plan. The Implementation Plan will set forth in detail the various tasks for construction and completion of the construction of the Tower and the Improvements for each BTS Site. Any material changes in the Implementation Plan shall be subject to written approval by SBCW, not to be unreasonably withheld or delayed. Vendor shall commence the Work pursuant to the Implementation Plan, using such means and methods of construction as will maintain the progress of the Work substantially in accordance with the Site Schedule for each BTS Site and shall cause Completion of each BTS Site in accordance with the requirements of the Site Schedule for such BTS Site. Section 6.04. Site Schedule. (a) To enable the Towers and the Improvements to be planned, scheduled and Completed in an orderly and expeditious manner, Vendor acknowledges and agrees that each Site Schedule shall be consistent with the Specifications and each stage of the Implementation Plan. As shall be provided in each Site Schedule for a BTS Site, following finalization of construction plans and receipt of required regulatory approvals, Vendor has eight (8) weeks to construct the BTS Site. Vendor and SBCW may agree to extend this date for a BTS Site in the applicable Site Schedule or otherwise in a writing between the parties. (b) Upon the occurrence of an event of Force Majeure, the Site Schedule for any affected BTS Site shall be adjusted to reflect all additional time which will be required for the performance of any of the duties or obligations of Vendor under this Agreement as a result of such event, which adjustment shall be subject to the prior written approval of SBCW, not to be unreasonably withheld or delayed. (c) Except as set forth in Section 6.04(b) as to an individual BTS Site, no Site Schedule for any BTS Site shall change, and Vendor will have no right to cause any such change, without prior written reasonable approval by SBCW. Within five (5) Business Days after the receipt of any request from Vendor for a change to any Site Schedule, SBCW shall notify Vendor in writing of its approval or disapproval of such proposed change. Failure of SBCW to respond within said five (5) Business Day period shall constitute and be deemed an acceptance of such requested change unless the change is, or results in an extension of the Scheduled Completion Date by more than thirty (30) days with respect to any BTS Site, in which case SBCW must approve such change in writing before it becomes effective, such approval not to be unreasonably withheld. 21 (d) Vendor acknowledges and agrees that it has an affirmative obligation and responsibility promptly to notify SBCW of any circumstance which affects or may affect any Site Schedule in any material respect and the extent to which such Site Schedule may be affected as a result of such circumstance. Section 6.05. Quality Review. Vendor shall establish and implement a program to monitor the quality of the construction, as set forth in the Implementation Plan. The purpose of the program shall be to assist in guarding against defects and deficiency in the Work.

Section 6.09. Site Data. In performing Services hereunder, Vendor shall compile data concerning each BTS Site and furnish such data to SBCW, all in accordance with the procedures set forth in Annex C and Annex G, including all Compliance Data and Completion Data. Section 6.10. Warranty. Vendor does hereby warrant and guarantee that the Tower and Improvements on each BTS Site and all workmanship and materials incorporated therein will be constructed in accordance with the Specifications and will be free from defects in workmanship and materials: (i) as to the Tower, for a period commencing on the Completion Date for such BTS Site and ending upon the expiration of the term of the Site Designation Supplement, after giving effect to any and all extensions thereof, and (ii) as to the Improvements and Constructed Improvements (to the extent made by Vendor as opposed to SBCW), for a period of one (1) year commencing on the Completion Date (the "Warranty Period"). In addition, at SBCW's request, Vendor shall assign to SBCW a nonexclusive right to enforce all warranties respecting materials used by Vendor in Completing each BTS Site and shall secure any and all consents from the suppliers of such materials to make such assignment effective or enforce any such warranties on behalf of SBCW. If any defect or deviation should exist, develop, be discovered or appear within the Warranty Period, Vendor, at its sole cost and expense, immediately upon demand, shall fully and completely repair, correct and eliminate such defect or deviation. The foregoing warranties and guarantees are cumulative of and in addition to, and not restrictive of or in lieu of, any and all other warranties and guarantees provided for or required by the Specifications, any other provision of this Agreement or applicable laws, and shall survive the expiration or termination of this Agreement. 24 Section 6.11. Access and Inspection. (a) The construction shall be performed in such a manner as will permit SBCW to inspect each BTS Site. SBCW may, at its election, conduct or have conducted such inspections as it deems necessary at each BTS Site. If SBCW notifies Vendor of any observed defects or nonconformities with the Specifications, Vendor shall promptly correct any defect or nonconformity in such time and manner as will permit Completion of each BTS Site in accordance with the Site Schedule for such BTS Site. The failure of SBCW to inspect any BTS Site, however, will not in any way limit, waive, or otherwise affect the rights of SBCW with respect to any of Vendor's warranties or obligations under this Agreement. (b) SBCW will have access to any BTS Site during all working hours, and will have the right to observe the Work performed; provided, however, that SBCW shall not delay, hinder or interfere with the performance of the Work. SBCW's inspection of any Work will not relieve Vendor of any of its obligations to perform the Work in accordance with this Agreement, including without limitation the Specifications, except to the extent a specific deviation from the Specifications at any BTS Site is or has been accepted in writing by SBCW. Work found not to be in accordance with the Specifications shall be replaced or re-performed by Vendor, except to the extent a specific deviation from the Specifications is or has been accepted in writing by SBCW. SBCW will have the right to reject materials and workmanship which are defective or not in conformance with the Specifications. Rejected Work at any BTS Site must be promptly removed from such BTS Site. Failure on the part of SBCW to reject defective or nonconforming Work will not be construed to imply an acceptance of such Work; provided, however, to the extent a specific deviation from the Specifications is or has been accepted in writing by SBCW, such deviation shall not be deemed to be defective or nonconforming Work. (c) Should SBCW consider it necessary or advisable at any time before Completion to examine Work already completed therein, Vendor shall, on request of SBCW, promptly furnish all necessary facilities, labor, and material for that purpose. If such Work is found to be defective in any material respect, Vendor shall pay all expenses of such examination. If, however, such Work is not found to be defective in any material respect, SBCW shall pay all expenses of such examination and restoration of the Work. The Site Schedule as to affected BTS Site shall be equitably adjusted. Section 6.12. Completion. (a) Promptly following the Completion of the Work at any BTS Site in accordance with the requirements of the Specifications and the requirements of this Agreement, including without limitation the construction of the Tower and the Improvements on such BTS Site and the performance of the final cleanup thereon, Vendor shall give SBCW written notice of its good faith belief that such BTS Site is Completed. Not later than twenty (20) days after receipt of such written notice, SBCW shall provide Vendor with written notice stating (i) SBCW agrees that the Work as to such BTS Site is Completed, whereupon the parties shall execute a Completion Certificate with respect to such BTS Site as soon as reasonably practicable after SBCW gives such notice, (ii) SBCW rejects such BTS Site as not Completed; provided SBCW includes an explanation in reasonable detail of the respects in which such BTS Site is not Completed, or (iii) SBCW exercises the option set forth in Section 6.12(c) to execute a Completion Certificate together with a Punch List. 25 (b) In addition to any right SBCW may have under Section 6.11, SBCW will have the right to (i) inspect any BTS Site at any time after SBCW receives the notification under Section 6.12(a) and prior to any date on which the Completion Certificate is executed and (ii) notify Vendor in writing if such inspection by SBCW reveals that Completion has not occurred with respect to any BTS Site. Promptly after receipt of any such notification, Vendor shall promptly cause any unperformed Work to be performed. (c) Upon issuance of the Completion Certificate with respect to a BTS Site, such BTS Site shall constitute a completed and accepted BTS Site (a "Completed BTS Site"). If at any time prior to issuance of Completion Certificate such BTS Site does not comply with the Specifications or other requirements of this Agreement in any material respect, SBCW may, at its sole option, elect to execute a Completion Certificate with respect to such BTS Site together with a punch list, in the form of Annex E attached hereto (the "Punch List"), indicating the particulars of the alleged deviation from the Specifications or other requirements of Vendor hereunder. Vendor shall promptly, but not later than within thirty (30) days of the date of the Punch List and at its own cost and expense, correct any such non-compliance or deviation. Upon execution of a Completion Certification and a Site Designation Supplement with respect to a BTS Site, SBCW shall commence payment to Vendor of the BTS Rent applicable to such BTS Site pursuant to the BTS Sublease. (d) Notwithstanding Section 6.12(c), if (i) any BTS Site becomes a Substantially Completed Site and (ii) at any time before the execution of the Completion Certificate or the Site Designation Supplement with respect to any BTS Site, SBCW installs and begins operation of SBCW's Communications Equipment on such BTS Site in a revenue generating mode, such BTS Site shall be deemed to constitute a Substantially Completed BTS Site, and from and after the date such BTS Site is deemed a Substantially Completed Site and such Communications Equipment has been in service, SBCW shall be obligated to pay Vendor (or Southern Towers, Inc. an Affiliate of Vendor) the applicable BTS Rent with respect to such BTS Site; provided, however, that in either case SBCW shall have the right to defer, accrue, and withhold payment of, the applicable BTS Rent until such BTS Site is Completed. Not later than thirty (30) days after any such BTS Site is Complete, SBCW shall pay such accrued BTS Rent, without interest. Article VII Guaranty Of Obligations Section 7.01.

Following the receipt of such notice by TowerCo Parent, TowerCo Parent shall have the same period of time as is afforded to Vendor under this Agreement to cure such default but no such cure period shall diminish the obligations of TowerCo Parent under this Section 7.01. (c) This guaranty obligation of TowerCo Parent shall be enforceable by SBCW in an action against TowerCo Parent without the necessity of any suit, action, or proceedings by SBCW of any kind or nature whatsoever against Vendor, without the necessity of any notice to TowerCo Parent of Vendor's default or breach under this Agreement and without the necessity of any other notice or demand to TowerCo Parent to which TowerCo Parent or Vendor might otherwise be entitled, all of which notices TowerCo Parent hereby expressly waives. TowerCo Parent hereby agrees that the validity of this guaranty and the obligations of TowerCo Parent hereunder shall not be terminated, affected, diminished, or impaired by reason of the assertion or the failure to assert by SBCW against Vendor any of the rights or remedies reserved to SBCW pursuant to the provisions of this Agreement or any other remedy or right which SBCW may have at law or in equity or otherwise. (d) TowerCo Parent covenants and agrees that this guaranty is an absolute, unconditional, irrevocable and continuing guaranty. The liability of TowerCo Parent hereunder shall not be affected, modified, or diminished by reason of any assignment, renewal, modification or extension of this Agreement or any modification or waiver of or change in any of the covenants and terms of this Agreement by agreement of SBCW and Vendor, or by any unilateral action of either SBCW or Vendor, or by an extension of time that may be granted by SBCW to Vendor or any indulgence of any kind granted to Vendor, or any dealings or transactions occurring between SBCW and Vendor, including, without limitation, any adjustment compromise, settlement, accord and satisfaction, or release, or any bankruptcy, insolvency, reorganization, arrangement, assignment for the benefit of creditors, receivership, or trusteeship affecting Vendor. TowerCo Parent does hereby expressly waive any suretyship defense it may have by virtue of any statute, law, or ordinance of any state or other governmental authority. (e) All of SBCW's rights and remedies under this guaranty are intended to be distinct, separate, and cumulative and no such right and remedy herein is intended to be the exclusion of or a waiver of any other. (f) TowerCo Parent hereby waives presentment demand for performance, notice of nonperformance, protest, notice of protest, notice of dishonor, and notice of acceptance. TowerCo Parent further waive any right to require that an action be brought against Vendor or any other person or to require that resort be had by SBCW to any security held by SBCW. 27 Article VIII Vendor's Additional Obligations As To Bts Sites Section 8.01.

(a) Subject to the terms and conditions of this Sublease, each Sublessor hereby lets, leases and demises unto TowerCo, and except as otherwise provided in Sections 3(h) and 22(b), TowerCo hereby leases, takes and accepts from Sublessor the Subleased Property of all of the Sites owned or leased by such Sublessor, in its "AS IS" condition, without any representation, warranty or covenant of or from SBCW or any SBCW Affiliate of SBCW whatsoever as to the condition thereof or the suitability thereof for any particular use, except as may be expressly set forth in the Agreement to Sublease. To SBCW's knowledge, the Towers are satisfactory in all material respects for SBCW's and its Affiliates' continuing use consistent with its Permitted Use of such Towers. Except as set forth above, TowerCo hereby acknowledges that neither SBCW nor any Affiliate or agent of SBCW has made any representation or warranty, express or implied, with respect to any of the Subleased Property, or any portion thereof, or the suitability or fitness for the conduct of TowerCo's business or for any other purpose, including the Permitted Use, and TowerCo further acknowledges that it has had or by its execution and delivery of a Site Designation Supplement, will have had sufficient opportunity to inspect and approve the condition of the Subleased Property of the Sites. (b) Each Site in addition to the Initial Sites shall be made subject to this Sublease by the execution and delivery of a Site Designation Supplement with respect thereto between Sublessor and TowerCo. SBCW and TowerCo acknowledge and agree that this Sublease is intended to constitute a single sublease covering the Subleased Property of all of the Sites and a single agreement covering all the Sites, and not a separate sublease and agreement covering individual Sites. (c) This Sublease is a grant of a leasehold interest in each Owned Site subject to all matters affecting Sublessor's right, title and interest in and to each Owned Site (including without limitation, Existing Subleases and the interests of third parties as to any Owned Sites that are subject to any Colocation Agreements); and, as to Leased Sites, this Sublease is a grant of a subleasehold interest in each Leased Site subject to all matters affecting title to Sublessor's leasehold interest, leasehold estate or other possessory interest therein (including without limitation, Existing Subleases and the interests of third parties as to any Leased Sites that are subject to Colocation Agreements). (d) TowerCo hereby acknowledges that, as to the Subleased Property of each Leased Site, this Sublease is a sublease by Sublessor under the provisions of, and is subject and subordinate to all of the terms and conditions of, the applicable Ground Lease of such Leased Site. As to any Leased Site, Sublessor shall not be deemed to have assumed any duty or obligation of the Ground Lessor 14 under the applicable Ground Lease and shall not be liable or responsible in any manner whatsoever for any failure of such Ground Lessor to perform any such duty or obligation. TowerCo agrees that it will promptly pay or cause to be paid the Ground Rent under each of the Ground Leases of the Leased Sites during the Term of this Sublease when such payments become due and payable and, in the event TowerCo fails to pay Ground Rent under any Ground Lease on a timely basis, TowerCo shall be responsible for any late charges, fees or interest payable to the Ground Lessor as a result thereof. Except as provided in Section 3(f) or 3(h), TowerCo shall (and with respect to its activities on the Reserved Space, each Sublessor Entity shall) abide by, comply in all respects with, and fully and completely perform all other terms, covenants, conditions, and provisions of each Ground Lease (including, without limitation, terms, covenants, conditions, and provisions relating to maintenance, insurance and alterations) as if TowerCo were the "ground lessee" thereunder and, to the extent evidence of such performance must be provided to the Ground Lessor of the applicable Ground Lease, TowerCo shall provide such evidence to Sublessor. TowerCo shall not engage in or permit any conduct that would: (i) constitute a breach of or default under any Ground Lease; or (ii) result in the Ground Lessor being entitled to terminate the applicable Ground Lease or to terminate Sublessor's right as ground lessee under such Ground Lease, or to exercise any other rights or remedies to which the Ground Lessor may be entitled for a default or breach under the applicable Ground Lease. During the Term of this Sublease, and subject to Section 3(f) below, Sublessor agrees to exercise prior to the expiration thereof and in accordance with the provisions of the applicable Ground Lease, any and all renewal options existing as of the applicable Site Commencement Date and as may be further extended or renewed by Sublessor pursuant to the terms of this Sublease, for any Leased Site under the Ground Leases of such Leased Sites; provided, however, that Sublessor shall not, be obligated to renew or otherwise extend the term of any applicable Ground Lease in the event such renewal or extension would extend the term of the Ground Lease beyond the Site Expiration Outside Date for such Leased Site unless TowerCo requests otherwise and Sublessor consents to such request (which consent shall not be unreasonably withheld). The applicable Sublessor shall (i) forward to the applicable Ground Lessor all requests for consents and other notices relating to the Permitted Use which TowerCo reasonably wishes to deliver to such Ground Lessor and (ii) deliver to TowerCo all material notices and communications received from the applicable Ground Lessor. (e) TowerCo shall not be entitled to act as agent for, or otherwise on behalf of, SBCW or any SBCW Affiliate or to bind SBCW or any SBCW Affiliate in any way whatsoever in connection with any Ground Lease or otherwise except as otherwise provided in this Section 3. (f) With respect to any negotiations with a Ground Lessor for the extension or terms of renewal of a Ground Lease (other than a renewal or extension pursuant to an option contained in such Ground Lease which Sublessor is obligated to exercise pursuant to Section 3(d)), TowerCo shall, in cooperation with Sublessor, at TowerCo's sole cost and expense, be responsible for and use commercially reasonable efforts to negotiate and obtain an extension or renewal of the Ground Leases of the Leased Sites on behalf of and for the benefit of Sublessor, and Sublessor shall make commercially reasonable efforts to assist TowerCo in obtaining such extension or renewal, provided that such extension or renewal does not impose any liability on Sublessor for which TowerCo is not responsible (or subsequently agrees to be responsible) under the terms of this 15 Sublease during the Term as to each Site. With respect to any amendment, renewal, extension or other change to the Ground Lease desired by TowerCo during the term pursuant to this Section 3, (i) Sublessor shall be entitled to consent to any such change (such consent not to be unreasonably withheld) and (ii) subject to the foregoing, Sublessor shall execute any such amendment, renewal, extension or change within ten (10) days of its receipt thereof from TowerCo without condition and shall bear any and all costs associated with its review. In the event TowerCo determines that it is unable or deems it undesirable to negotiate the terms of renewal or extension of the Ground Lease directly with the Ground Lessor, Sublessor may attempt to negotiate such renewal or extension and TowerCo shall reimburse Sublessor for its reasonable out-of-pocket expenses relating to such negotiation unless TowerCo exercises its termination right provided in the following sentence within the applicable time period. If Sublessor completes the foregoing negotiations for such extension or renewal, the Site Expiration Date shall be extended to the Site Expiration Outside Date set forth in the Site Designation Supplement provided, however, that if in connection with such renewal or extension Sublessor, without the approval of TowerCo, agrees to any increase in Ground Rent over the then-current Ground Rent or agrees to any revenue sharing in excess of existing revenue sharing arrangements, TowerCo shall have the option, exercisable within thirty (30) days of receipt of notice of the extension or renewal, of terminating its subleasehold interests in such Site as of the date the Ground Lease would have expired had Sublessor not extended or renewed such Ground Lease. If Sublessor or TowerCo is not able, after using commercially reasonable efforts, to extend or renew any Ground Lease in accordance with this Section 3(f), then the Parties shall permit such Ground Lease to expire on the applicable expiration date and this Sublease shall have no further force and effect as to the Subleased Property of the Leased Site to which such Ground Lease applies. Each of TowerCo and TowerCo Parent agrees that neither it, nor any of its Affiliates, may seek to obtain, obtain or hold, any interest in any Ground Lease or its underlying fee interest that is superior or prior to Sublessor's interests in such Ground Lease. SBCW or an SBCW Affiliate shall have the right to acquire the fee simple interest in the Site from the Ground Lessor whereupon such Site shall be deemed an Owned Site, in which event TowerCo shall have a leasehold interest in such Owned Site. Except as provided in this Section 3(f), or as TowerCo may otherwise agree or direct, during the Term Sublessor shall not take any action to amend or supplement any Ground Lease, other than to exercise renewals as expressly provided herein which each Sublessor covenants to do as provided above. In addition to the foregoing, Sublessor agrees that it shall use its good faith efforts to cooperate with TowerCo's exercise of (or right to exercise any of) its rights under this Sublease with respect to the Ground Lease and the Ground Lessor, including, without limitation, pursuant to this Section 3. (g) Subject to Section 24 and Section 25, Sublessor's right to sell, convey, transfer, assign or otherwise dispose of Sublessor's interest in and to any Site (including Sublessor's interest in and to the Subleased Property of such Site) shall be unrestricted. (h) Notwithstanding anything to the contrary contained herein, SBCW represents to TowerCo that, as of the applicable Site Commencement Date, each Ground Lease for a Leased Site is or will be in full force and effect and Sublessor is not or will not be in default under any such Ground Lease in any material respect as a result of Sublessor's acts or omissions. Each Sublessor shall perform any obligations under and comply with the terms of each of the Ground Leases, but only if such obligations are expressly reserved to Sublessor for its performance under the terms of this Sublease. Upon receipt by Sublessor of any notice of default or notice of an act or omission which could with the passing of time and/or the giving of notice constitute an event of default under a Ground Lease or non-compliance with a term of a Ground Lease (the "Default Notice"), SBCW shall, within five (5) business days after receipt of the Default Notice or such shorter time as is reasonably necessary to avoid a termination of such Ground Lease, provide TowerCo with a copy of the Default Notice. If such default or non-compliance with a term of a Ground Lease is caused by TowerCo or any Space Subtenant, TowerCo shall, and shall cause the applicable Space Subtenant to, cure or otherwise remedy such default or noncompliance. Notwithstanding anything in this Sublease to the contrary, unless an obligation under a Ground Lease is expressly reserved under this Sublease for performance by a Sublessor, any default referred to in the Default Notice shall constitute a default by TowerCo under this Sublease. 16 (i) Unless an event of default by TowerCo shall have occurred and be continuing, TowerCo, at its own cost and expense, may from time to time make, subject to the requirements of Section 12, such Alterations that are not required pursuant to Section 11(a) as TowerCo may deem desirable in the proper conduct of its business, so long as (i) such Alteration shall not disrupt or otherwise adversely affect SBCW's or its Affiliate's Permitted Use of the Site or portion thereof and is made in accordance with the requirements set forth in Section 12 hereof, (ii) such Alteration shall not result in any material respect in (y) the value of the Site or portion thereof being less than the value thereof immediately prior to such Alteration, or (z) the economic life of the Site or portion thereof being less than the economic life of the Site or portion thereof immediately prior to such Alteration, (iii) such Alteration shall not cause the Site or portion thereof to constitute "limited use property" within the meaning of Rev. Proc. 76-30, 1976-2 C.B. 647, and (iv) no Alterations, taken together or separately, shall fail to comply with the provisions of Rev. Proc. 75-21, 1975-1 C.B. 715 or 79-48, 1979-1 C.B. 529. Notwithstanding anything to the contrary contained in this Section 3(i), TowerCo, at its own cost and expense, may from time to time make Alterations (including, without limitation, Nonseverable Improvements that may be required by Law), which do not comply with subclause (iv) of the immediately preceding sentence ("Non-Conforming Alterations") provided that (i) the Non-Conforming Alterations otherwise satisfy the terms and provisions of this Section 3(i), and (ii) the applicable Sublessor does not make TowerCo's proposed Non-Conforming Alterations in accordance with the remainder of this Section 3(i). In the event that TowerCo desires to make Non-Conforming Alterations, TowerCo shall submit written notice to the applicable Sublessor describing such proposed Non-Conforming Alterations in reasonable detail. Such Sublessor shall elect whether to make or cause to be made, at such Sublessor's cost and expense, the Non-Conforming Alterations by written notice provided to TowerCo within ten (10) days after receipt of TowerCo's proposal regarding the Non-Conforming Alterations. Such Sublessor's failure to respond to TowerCo within such ten (10) day period shall be deemed to be such Sublessor's election not to make such Non-Conforming Alterations. In the event such Sublessor elects to make the Non-Conforming Alterations and such Sublessor and TowerCo agree on terms and conditions, including, but not limited to, the amount and timing of rent with respect to such Non-Conforming Alterations ("Additional Rent"), then such Sublessor shall make the Non-Conforming Alterations in accordance with plans and specifications, and according to a time schedule, provided by TowerCo and reasonably acceptable to such Sublessor. In the event that such Sublessor elects, or is deemed to have elected, not to make the Non-Conforming Alterations 17 or such Sublessor and TowerCo shall not have agreed on terms and conditions, TowerCo may make such Non-Conforming Alterations and, notwithstanding anything to the contrary contained in this Sublease (other than the other conditions contained in this Section 3(i)), title to the Non-Conforming Alterations shall without further act or instrument act or instrument vest in TowerCo. Upon the expiration or earlier termination of this Sublease as to a Site at which Non-Conforming Alterations have been made, the following provisions shall apply: (i) if TowerCo has not exercised its option to purchase such Site and TowerCo has made any Non-Conforming Alterations, the applicable Sublessor may purchase such Non-Conforming Alterations from TowerCo at a price equal to the then fair market value of such Non-Conforming Alterations, (ii) if TowerCo has exercised its option to purchase such Site, TowerCo shall purchase such Site at a purchase price equal to the Option Purchase Price Amount, plus the then fair market value of the Non-Conforming Alterations and/or Sublessor Alterations, if any, made to such Site, and (iii) if TowerCo has not exercised its option to purchase such Site, TowerCo has made Non-Conforming Alterations, and the applicable Sublessor does not purchase such Non-Conforming Alterations from TowerCo, TowerCo shall continue to hold such Non-Conforming Alterations, and all rent and any sales proceeds attributed to such Site thereafter shall be allocated between the applicable Sublessor and TowerCo in accordance with their relative interests in such Site (as determined below). In each of subclauses (i) and (ii) of the immediately preceding sentence, the applicable party shall pay the purchase price in cash or immediately available funds. In each of the subclauses (i) and (ii), the then fair market value of the Non-Conforming Alterations and/or Sublessor Alterations shall equal the excess of the then fair market value of such Site including such Non-Conforming Alterations and/or Sublessor Alterations over the estimated then fair market value of such Site without such Non-Conforming Alterations and/or Sublessor Alterations. The applicable Sublessor and TowerCo shall attempt, in good faith, to agree on the then fair market value of the Non-Conforming Alterations and/or Sublessor Alterations (or the relative interests of the applicable Sublessor and TowerCo, if applicable) or, alternatively, shall attempt, in good faith, to agree on an independent qualified appraiser to determine such fair market value and the fair market values of the Non-Conforming Alterations and/or the Sublessor Alterations (or the relative interests of the applicable Sublessor and TowerCo, if applicable). Absent agreement on value or on an appraiser within thirty (30) days, each of such Sublessor and TowerCo shall identify an independent qualified appraiser within ten (10) days thereafter. If either party fails to appoint an appraiser within such ten (10) day period, the appraiser appointed by the other party shall alone determine such fair market value. If two appraisers are appointed and such appraisers cannot agree on the then fair market value (or the relative interests of the applicable Sublessor and TowerCo, if applicable), each such appraiser shall identify a third independent qualified appraiser who shall determine the then fair market value of the Non-Conforming Alterations and/or Sublessor Alterations and the relative fair market values of the Non-Conforming Alterations and/or the Sublessor Alterations (or the relative interests of Sublessor and TowerCo, if applicable) (collectively, the "Valuation Process"); provided that if such two appraisers cannot agree on the identity of such third appraiser within ten (10) days after the appointment of the second appraiser, either party may apply to the American Arbitration Association for the appointment of such appraiser. If TowerCo exercises its option to purchase the Site, the fair market value of the Non-Conforming Alterations and/or the fair market value of the Sublessor Alterations shall be paid to the party which made such Alterations. 18 SECTION 4. Existing Subleases and Colocation Agreements. (a) Without limiting the generality of Section 3, TowerCo expressly acknowledges that, as to each Site, this Sublease is subject to all Existing Subleases affecting such Site, including, without limitation, Existing Subleases executed prior to the applicable Site Commencement Date pursuant to any Colocation Agreement. In respect of each Site, by execution of this Sublease or a Site Designation Supplement the applicable Sublessor does transfer, assign and convey over unto TowerCo, for the Term of this Sublease in respect of such Site, all of its rights, title and interest as "sublandlord" or "sublessor" in, to or under any Existing Subleases affecting such Sites and does hereby delegate all of Lessor's duties, obligations and responsibilities under the Existing Subleases to TowerCo. TowerCo does hereby assume and agree to pay and perform all of the duties, obligations, liabilities and responsibilities of Sublessor as "sublandlord" or "sublessor" under the Existing Subleases affecting each Site arising from and after the date of the Site Designation Supplement for such Site and commencing on the Site Commencement Date for such affected Site, TowerCo shall receive all rents payable thereunder. (b) From time to time, SBCW shall give TowerCo written notice of the intent of third parties to Colocation Agreements to occupy any Available Space, and promptly following receipt of such notice, TowerCo shall cooperate with SBCW and the applicable third party so as to facilitate such third party's occupancy of such Available Space on commercially reasonable terms. (c) TowerCo shall, and does hereby agree to, indemnify, defend and hold the SBCW Indemnitees harmless from, against and in respect of any and all Claims, paid, suffered, incurred or sustained by any SBCW Indemnitee and in any manner arising out of, by reason of, or in connection with any failure of the duties, obligations, liabilities and responsibilities of a Sublessor as "sublandlord" or "sublessor" under any of the Existing Subleases affecting each Site and arising from and after the Site Commencement Date for such Site, to be fully and completely performed pursuant to the Existing Subleases, except to the extent caused by an SBCW Indemnitee. (d) Unless TowerCo exercises the purchase option with respect to a Site under Section 35 hereof, the assignment by each Sublessor to TowerCo of the Existing Subleases in respect of each Site shall automatically terminate and expire, such Existing Subleases shall automatically be reassigned to each Sublessor or its designee, and each Sublessor or its designee shall accept such reassignment, upon the expiration of the Term of, or earlier termination of, this Sublease in respect of such Site. SECTION 5. Reserved Space. (a) TowerCo expressly acknowledges that, as to any Site, the Subleased Property of such Site does not include, and that each Sublessor has reserved and excepted from this Sublease, the Reserved Space of such Site for SBCW's and its Affiliates' exclusive possession and use, regardless of whether or not such Reserved Space is now or hereafter occupied; and, TowerCo further expressly acknowledges that, as between each Sublessor and TowerCo, the Reserved Space of 19 each Site shall, at all times during the Term of this Sublease, be deemed to be leased or subleased to TowerCo pursuant hereto and leased back to SBCW (for the benefit of SBCW or any of its Affiliates) pursuant hereto. As an appurtenance to, and a part of, the Reserved Space of each Site, each Sublessor (for the benefit of SBCW or any of its Affiliate) also reserves: (i) the right of ingress to and egress from the entire Site, and access to the entire Tower and all Improvements to such Site and Tower (including any and all easements), at such times (on a 24-hour, seven (7) day per week basis unless otherwise limited by the Ground Lease or other restrictions of record that have priority over the Sublease), to such extent, and in such means and manners (on foot or by motor vehicle, including trucks and other heavy equipment), as SBCW deems necessary or desirable in connection with its or its Affiliates' full use and enjoyment of the Reserved Space, including, without limitation, the construction, installation, use, operation, maintenance, repair and replacement of its Communications Facility thereon; and (ii) the right to use any portion of the Subleased Property of a Site, including the Land and Improvements thereof, for purposes of temporary location and storage of any equipment (including Communications Equipment) and any part thereof in connection with performing any repairs or replacements of such Person's Improvements; provided, however, that such storage shall not have a material adverse effect on Space Subtenants' Permitted Use. (b) Subject to the availability of Available Space on the applicable Tower at the time of the proposed expansion, SBCW may at any time expand the Reserved Space on up to three hundred (300) Towers by the addition or replacement of Communications Equipment on such Tower up to an additional fifteen percent (15%) of the total tower loading on such Tower; provided that as a result of the exercise of such expansion right SBCW shall not be entitled to occupy more than two (2) platforms on any Tower. (For the avoidance of doubt, if SBCW or its Affiliate occupy one (1) platform at the time of expansion, SBCW or its Affiliate may expand to occupy only one additional platform, and if SBCW or its Affiliates occupy two (2) platforms at the time of such expansion, SBCW or its Affiliate may expand on one or both of the platforms it then occupies but may not expand to occupy an additional, third platform.) SBCW may exercise the foregoing expansion right for itself or for the use and benefit of any of its Affiliates. (c) Without limiting SBCW's rights under Section 24(a) hereof and subject to the availability of Available Space on the applicable Tower at the time of the proposed expansion, SBCW shall have the further right to expand the amount of equipment on the Towers beyond the first three hundred (300) Towers, provided that SBCW shall pay TowerCo as additional Leaseback Charge $100 per month per panel/antenna or space equivalent of one panel/antenna, but in no event in an amount to exceed $1600 per platform, or if SBCW locates any such expanded equipment on a platform which is not already occupied by SBCW's Communication Equipment, not to be less than $1200 per any such additional platform (except with respect to microwave dishes and related equipment), such amount to be in addition to the SBCW Leaseback Charge due and payable to TowerCo pursuant to Section 10. Such amounts shall increase each year after the date hereof five percent (5%) per year, until the tenth anniversary of the applicable Site Commencement Date and thereafter pursuant to Section 10(f). SBCW may exercise the foregoing expansion right for itself or for the use and benefit of any of its Affiliates. (d) Notwithstanding anything to the contrary contained herein, the Parties acknowledge and agree that the Reserved Space of each Site will include, without limitation, all portions of such Site utilized or occupied by SBCW or its 20 Affiliate as of the applicable Site Commencement Date for such Site for the use, enjoyment, operation or maintenance of Communications Facility on such Site for the Permitted Use. If at any time between the date hereof and the applicable Site Commencement Date, SBCW or its Affiliate elects to increase the amount of equipment on a Tower on a Site, then SBCW shall have an option, exercisable at its sole discretion upon written notice to TowerCo prior to the applicable Site Commencement Date, to (i) count such Tower toward three hundred (300) Towers in accordance with Section 5(b) and pay the amount of SBCW Leaseback Charge determined in accordance with Section 10(b) with respect to such Site, or (ii) pay TowerCo, the amount of SBCW Leaseback Charge determined in accordance with Section 5(c). (e) The parties acknowledge and agree that antenna mounting hardware constitutes a portion of the Improvements and does not constitute part of the Reserved Space. If, as to any Sites, SBCW or any SBCW Affiliate desires to exercise its Right of Substitution pursuant to Section 24(b), to move any of its Communications Equipment on such Tower to any Available Space, and such exercise would require relocation of the existing antenna mounting hardware to accommodate such move, TowerCo shall move such antenna mounting hardware as requested by SBCW or such SBCW Affiliate, unless (i) other Space Subtenants are sharing the same antenna mounting hardware, (ii) such relocation would adversely affect the rights of other Space Subtenants or (iii) TowerCo otherwise determines that such relocation is not feasible or beneficial. If TowerCo does relocate SBCW or such SBCW Affiliate's antenna mounting hardware in response to the exercise of the Right of Substitution, SBCW or such SBCW Affiliate shall reimburse TowerCo for the reasonable costs directly attributable to such relocation. If as contemplated by the foregoing, TowerCo does not or cannot relocate the existing antenna mounting hardware, TowerCo shall, at its sole cost and expense, install suitable mounting hardware at the location on the Tower designated by SBCW or the applicable SBCW Affiliate, so as to accommodate the requested relocation; provided that SBCW or such SBCW Affiliate shall remain responsible for the payment of all costs and expenses associated with moving its antennas to the antenna mounting hardware supplied by TowerCo. (f) If SBCW or any SBCW Affiliate desires to add or relocate any antennas to the Tower location of any Site, the provisions of Sections 24(a)(i) and (a)(ii) shall apply. Upon the request of either Party, the Parties shall promptly execute such instruments as may be reasonably required to further evidence such addition or relocation, including without limitation an amendment to the applicable Site Designation Supplement, and shall cause such amendment to be recorded at SBCW's or such SBCW Affiliate's cost and expense, unless the Parties otherwise agree. SECTION 6. Permitted Use. (a) TowerCo shall use, and shall permit the use of, the Subleased Property of each Site only for the Permitted Use. (b) TowerCo shall not use, or permit to be used, the Subleased Property of any Site, or any portion thereof, by TowerCo, any Person (other than SBCW or its Affiliates) or the public in such manner as might reasonably tend to impair Sublessor's title to or interest in such Site, or any portion thereof, or in such manner as might reasonably make possible a Claim or Claims of adverse usage 21 or adverse possession by the public, as such, or any Person (other than SBCW or its Affiliate), or of implied dedication of such Subleased Property, or any portion thereof. Nothing contained in this Sublease and no action or inaction by SBCW or its Affiliates shall be deemed or construed to mean that Sublessor has granted to TowerCo any right, power or permission to do any act or make any agreement that may create, or give rise to or be the foundation for any such right, title, interest, lien, charge or other encumbrance upon the estate of Sublessor in any Site. (c) SBCW shall not use, or permit to be used, the Reserved Space of any Site, or any portion thereof, by SBCW, any Affiliate thereof, any other Person (other than TowerCo and Space Subtenants) or the public in such manner as might reasonably tend to impair TowerCo's right as a sublessor with respect to such Site, or any portion thereof, or in such manner as might reasonably make possible a Claim or Claims of adverse usage or adverse possession by the public, as such, or any Person (other than TowerCo and Space Subtenants), or of implied dedication of such Reserved Space, or any portion thereof. Nothing contained in this Sublease and no action or inaction by TowerCo shall be deemed or construed to mean that TowerCo has granted to SBCW or any Affiliate thereof any right, power or permission to do any act or make any agreement that may create, or give rise to or be the foundation for any such right, title, interest, lien, charge or other encumbrance upon the leasehold estate of TowerCo in any Site. SECTION 7. Access. The Subleased Property of a Site includes, as an appurtenance thereto, a non-exclusive right for access to the Subleased Property of each Site on a 24-hour, seven (7) day per week basis, on foot or motor vehicle, including trucks and other heavy equipment, for the installation and maintenance of the Tower and Improvements thereof and the Communications Facilities of Space Subtenants. The Parties acknowledge and agree that the right to access the Subleased Property of each Site, or any portion thereof, granted pursuant to this Section 7 shall be granted to TowerCo and its authorized contractors, subcontractors, engineers, agents, advisors, consultants, representatives, or other persons authorized by TowerCo and, under TowerCo's direct supervision, and to Space Subtenants, subject to any restrictions contained in the applicable Ground Lease. SECTION 8. Term. (a) The term of this Sublease, as to each Site, shall commence on the Site Commencement Date set forth in the Site Designation Supplement with respect thereto and shall expire on the Site Expiration Date therefor. (b) No surrender by TowerCo to the Sublessor of the Subleased Property of any Site or any portion thereof, prior to the expiration of the Term as to such Site shall be valid or effective unless agreed to and accepted in writing by such Sublessor, and no act by such Sublessor, other than such a written acceptance, shall constitute an acceptance of any such surrender. (c) As to any Site, upon expiration or earlier termination of this Sublease, TowerCo shall, at its cost and expense and upon instructions from SBCW, (i) within a reasonable period of time, but in no event less than thirty (30) days, 22 stop and cease, and cause the Space Subtenants on such Site to stop and cease, the operation of its Communications Facilities on such Site and shall remove all of TowerCo's Severable Alterations from such Site and restore each Site substantially to the condition it was in on the applicable Site Commencement Date, subject to the addition of any permitted Non-Severable Alterations. Any Severable Alterations not removed by TowerCo within said 15-day period shall be deemed abandoned by TowerCo and title thereto shall automatically, without further action, vest in the Sublessor of such Site. SECTION 9. Withdrawal. (a) Notwithstanding anything to the contrary contained herein, SBCW will have the Withdrawal Right for the benefit of itself or its Affiliates, exercisable in respect of any Site on the tenth anniversary of the applicable Site Commencement Date and on each five-year anniversary of such date thereafter. To exercise any such Withdrawal Right, SBCW shall give TowerCo written notice of such exercise not less than ninety (90) days, in the case of the exercise of a Withdrawal Right in respect of less than twenty percent (20%) of all Sites now or hereafter under this Sublease and one hundred eighty (180) days, in the case of the exercise of a Withdrawal Right in respect of twenty percent (20%) or more of all Sites now or hereafter under this Sublease, prior to any such anniversary (the "Withdrawal Notice"). If SBCW exercises the Withdrawal Right as to any Site, SBCW shall not be required to pay the SBCW Leaseback Charge with respect to such Site for the period occurring after the Withdrawal Date and the Withdrawal Date as to such Site shall be the date specified in the applicable Withdrawal Notice. Not later than the Withdrawal Date of any Site, SBCW or its Affiliate shall vacate the Reserved Space of such Site if such Reserved Space is occupied whereupon SBCW's or its Affiliate's sublease of such Reserved Space pursuant hereto and SBCW's or its Affiliate's right to occupy and use the Reserved Space of such Site as a sublessee hereunder shall be terminated. At the request of either SBCW or TowerCo, the appropriate parties shall enter into documentation, in form and substance reasonably satisfactory to such parties, evidencing any withdrawal effected hereunder. (b) In addition to and not in limitation of any right of SBCW under Section 9(a), SBCW will have the right, exercisable at any time during the Term of this Sublease, to cease occupying the Reserved Space of any Site, and retain its right to such Reserved Space and may permit a SBCW Affiliate to occupy such Site, so long as SBCW continues to pay the SBCW Leaseback Charge in respect of such Site. SECTION 10. Rent and SBCW Leaseback Charge. (a) TowerCo shall prepay Rent (other than Additional Rent) in respect of the Subleased Property of each Site, for the entire Term on the Site Commencement Date for each Site. TowerCo shall pay Additional Rent in such time, manner and amounts as determined pursuant to Section 3(i) hereof. Each month during the Term as to each Site, SBCW shall pay, or cause its Affiliate to pay, the SBCW Leaseback Charge in respect of the Reserved Space for such Site which is subject to this Sublease, in advance on or prior to the tenth (10) day of such calendar month, beginning on the Site Commencement Date for such Site. (b) The following terms shall have the following definitions: 23 "Rent" means, as to any Site the rental amount prepaid by TowerCo for the leasing of the Sites pursuant to this Sublease as set forth in Annex A to the Agreement to Sublease and to be set forth on the Site Designation Supplement and any Additional Rent with respect to such Site. "SBCW Leaseback Charge" means, as to any Reserved Space, the monthly rental amount payable to TowerCo for the leaseback of the Reserved Space on such Site to SBCW or its Affiliate pursuant to this Sublease equal as to any Site in any Site Term Year, an amount equal to $1,400 per month subject to an increase of the lesser of (x) the applicable CPI Change plus four percent (4%) or (y) five percent (5%) per year (but never less than zero percent (0%)) on each anniversary of the Effective Date. (c) TowerCo shall pay a late charge of five percent (5%) of any amount payable by TowerCo under the provisions of this Sublease, which shall be paid within ten (10) days after the date the same is due; provided, however, that the late charge shall not be assessed in respect of the first late payment occurring in any Site Term Year. (d) If the Site Commencement Date for any Site is a day other than the first day of a calendar month, the applicable SBCW Leaseback Charge for the period from such Site Commencement Date through the end of the calendar month during which such Site Commencement Date occurs shall be prorated on a daily basis, and shall be included in the calculation of the SBCW Leaseback Charge for the first full calendar month of the Term, on the first day of the first calendar month following such Site Commencement Date. (e) SBCW or its Affiliate shall pay a late charge of five percent (5%) of any SBCW Leaseback Charge payable by SBCW or its Affiliate under the provisions of this Sublease, which shall be paid within ten (10) days after the date the same is due; provided, however, that the late charge shall not be assessed in respect of the first late payment occurring in any Site Term Year. Notwithstanding the foregoing, if SBCW or its Affiliate fails to pay any portion of a SBCW Leaseback Charge because SBCW or its Affiliate, acting in good faith, reduced the amount of SBCW Leaseback Charge payable to TowerCo due to a mistaken belief that it was entitled to Reimbursable Maintenance Expenses under Section 29(a), no late charge shall be payable in respect thereof. (f) Notwithstanding anything to the contrary contained herein, if after the tenth (10th) anniversary of the applicable Site Commencement Date, the then current SBCW Leaseback Charge payable to TowerCo with respect to any Site is below the market rate agreed upon by the Parties at the time of determination, then such SBCW Leaseback Charge shall automatically be increased on such anniversary and on each anniversary thereafter, based on the CPI Change effective as of date of such anniversary. If, however, the then SBCW Leaseback Charge payable to TowerCo with respect to such Site is above the market rate, then such SBCW Leaseback Charge shall be automatically reset at ninety percent (90%) of such agreed upon market rate effective as of such tenth (10th) anniversary of the applicable Site Commencement Date and shall increase on each following anniversary at the then current annual market rate of increase for comparable properties. Notwithstanding anything to the contrary contained herein, the Parties shall agree as to the market rate not later than sixty (60) days prior to such tenth anniversary of the applicable Site Commencement Date. If the Parties are unable to agree upon the market rate, then SBCW shall have an option, exercisable by written notice to TowerCo, to exercise its Withdrawal Right in accordance with Section 9(a). 24 SECTION 11. Condition of the Sites and Obligations of TowerCo. (a) TowerCo acknowledges that, as between TowerCo and SBCW, in respect of each Site, TowerCo has the obligation, right and responsibility to repair and maintain such Site, including without limitation, an obligation to monitor each Tower to maintain the structural integrity of the Tower and the ability of the Tower to hold and support all Communications Equipment then mounted on the Tower, in accordance with all applicable Laws and standard industry practices. Subject to the other provisions contained in this Sublease, TowerCo, at its sole cost and expense, except if such cost or expense arises out of a negligent or wrongful act or omission of SBCW or its Affiliates, shall monitor, maintain and repair each Site such that SBCW or its Affiliates and Space Subtenants may utilize such Site to the extent permitted herein, including, without limitation, each Tower lighting system (to the extent required by applicable Law) and markings and the structural integrity of each Tower. Installation, maintenance and repair of each Site must comply with all Laws applied in a manner consistent with standard industry practices. TowerCo's duties include, without limitation, subject to the other provisions contained in this Sublease, maintenance of appropriate records and notification to the FAA of any failure on TowerCo's part and repairs and correction of same. TowerCo assumes all responsibilities, as to each Site, for any fines, levies, and/or other penalties imposed as a result of non-compliance with said requirements of said authorities unless such non-compliance occurs on or prior to the Site Commencement Date for any such Site (in which event SBCW or the applicable SBCW Affiliate shall be responsible for such fines, levies and/or other penalties). TowerCo shall cause Space Subtenants to maintain and repair all Communications Equipment on each Site, in accordance with the requirements of this Sublease including without limitation as set forth in Exhibit C; provided, however, that nothing in this Sublease shall require TowerCo to maintain SBCW's or its Affiliate's Communications Equipment. Without limiting the foregoing, TowerCo at its own cost and expense, shall make (or cause to be made) all Alterations to the Sites as may be required from time to time to meet in all respects the requirements of applicable Laws (regardless of the Person upon whom such requirements, by their terms, are nominally imposed). (b) For each Site, TowerCo, at its sole cost and expense, shall provide SBCW all necessary and appropriate information requested by SBCW for SBCW to obtain (and SBCW will obtain within a reasonable amount of time) all of the certificates, permits, and other approvals which may be required in connection with FCC or FAA regulations. TowerCo shall also provide SBCW all appropriate information requested by SBCW pertaining to any easements or consents which are required from any third parties with respect to the operation of such Site, including the lighting system serving such Site, SBCW shall cooperate with TowerCo in connection therewith, as contemplated by Section 17. Nothing in this Sublease shall require TowerCo to provide any information necessary for SBCW to obtain any certificate, permit or other approval relating specifically and only to SBCW's Communications Equipment. If, as to any Site, or any portion thereof, any certificate, permit, license, easement, or approval relating to the operation of such Site is canceled, expires, lapses, or is otherwise withdrawn or terminated or, if TowerCo has breached its obligation under this Section 11(b), then SBCW shall have the right, in addition to its other remedies pursuant to this 25 Sublease, at law, or in equity, to take appropriate action to remedy any such noncompliance and demand reimbursement for any expenses incurred in connection therewith from TowerCo, and/or to terminate this Sublease as to such Site subject to Sections 29 and 30. (c) For each Site, TowerCo agrees to monitor the lighting system serving such Site and will notify the appropriate FAA service office of any lighting failure within thirty (30) minutes of discovering such failure. In addition, TowerCo agrees, as soon as practicable, to begin a diligent effort to repair the failed lighting on an Emergency basis, and to notify SBCW upon successful completion of the repair. Notwithstanding anything to the contrary contained in Section 30, TowerCo's failure to (i) successfully schedule such repair and notify SBCW, in each case as soon as practicable but in any event no later than within twenty-four (24) hours of receiving such notice and (ii) repair the failed lighting within five (5) days, constitutes default by TowerCo under this Sublease. Notwithstanding anything to the contrary contained herein, TowerCo agrees to indemnify, defend and hold each SBCW Indemnitee harmless from and against any Claims arising out of or by reason of any failed lighting whether or not TowerCo shall have complied with the provisions of this Section 11(c) unless such Claims arise out of or by reason of SBCW Indemnitee's gross negligence or willful misconduct. In addition to and not in limitation of Sections 30(d) and (e), if TowerCo defaults under this Section 11(c), SBCW, in addition to its other remedies pursuant to this Sublease, at law, or in equity, may elect to take appropriate action to repair or replace lights and invoice TowerCo. In addition, SBCW may terminate this Sublease as to such Site within fifteen (15) days of the occurrence of such default; provided, that such default is not cured within the aforementioned fifteen (15) days period. Without in any way affecting TowerCo's obligations relating to lighting: (i) in order to accommodate TowerCo's needs during the transition period, SBCW agrees to monitor the lighting system serving the Towers or the Improvements of the Sites from the respective dates of the Site Designation Supplements until the expiration of two calendar months after the Final Closing Date (as defined in the Agreement to Sublease); (ii) during the entire Term, SBCW shall have the right, at its expense, to install and maintain equipment for the purpose of monitoring (x) the lighting system serving the Tower or the Improvements of each Site, and/or (y) any device of TowerCo's used to monitor the lighting system serving each Tower; and (iii) TowerCo shall have the right, at its expense, to install and maintain equipment for the purpose of monitoring any device of SBCW's or SBCW Affiliate's used to monitor the lighting system servicing any Tower. At TowerCo's election, SBCW shall (i) provide TowerCo a data feed for a fee and on terms to be agreed (x) from all appropriate security monitoring devices now at the Tower (it being understood that these devices will be leased or subleased to TowerCo with each Tower, and that TowerCo will be responsible for the repair and maintenance of the devices and their wiring up to the point of hand-off to SBCW's T1 at the Site) and (y) from any additional devices which TowerCo wishes to install, at TowerCo's sole cost and expense; (ii) permit TowerCo access to the contact point box at each Tower where TowerCo may install, at TowerCo's sole cost and expense, its own direct links to such devices; or (iii) permit TowerCo, where available, access to the contact point for each Tower through SBCW's regional switching (it being understood that TowerCo shall be responsible for providing its own dedicated telephone lines to the Site, that these monitoring devices will generally be subleased to TowerCo with each Tower, and that TowerCo will be responsible for the repair and maintenance of the devices and their wiring up to the point of hand-off to TowerCo's dedicated lines). 26 (d) Without limiting TowerCo's obligations under this Section 11 and the other provisions of this Sublease, the Parties acknowledge that SBCW and the SBCW Affiliates are licensed by the FCC to provide telecommunications services and that the Sites are used to provide those services. Nothing in this Sublease shall be construed to transfer control of any FCC authorization held by SBCW or the SBCW Affiliates to TowerCo or to limit the right of SBCW and the SBCW Affiliates to take all necessary actions to comply with their obligations as an FCC licensee or with any other legal obligations to which they are or may become subject. SECTION 12. Requirements for Alterations; Title to Alterations; Addition of Equipment; Work on the Site. (a) All Alterations that are made to a Site (whether required or optional) shall comply with the requirements of clauses (i), (ii), (iii) and (iv) of Section 3(i) hereof. Subject to Section 3(i), title to each Alteration shall without further act or instrument vest in the Sublessor of such Site and be deemed to constitute a part of the Site and be subject to this Sublease provided that any such Alteration is required pursuant to Section 11 (a) or is a Nonseverable Alteration. Title to all other Alterations shall vest in TowerCo. Any such Alteration may be removed by TowerCo, at its own cost and expense, at any time prior to the end of the Term for the applicable Site if such removal will not cause the Site to be in violation of any applicable Law. Any such Alteration may also be removed at the expiration of the Term so long as the Site restored substantially to its condition (normal wear and tear excepted) prior to the making of such Alteration; provided, however, that any Severable Alterations that are not removed from a Site within 15-days after at the time of its surrender by TowerCo shall become the property of the Sublessor of the Site as provided in Section 8(c) hereof. (b) Whenever TowerCo is permitted or required to make Alterations to any Site; construct, replace, maintain or repair the Tower and Improvements of any Site; maintain or repair, or cause Space Subtenants to maintain or repair, any Communications Equipment, or reconstruct or restore, Subleased Property (hereinafter called the "TowerCo Work"), the following provisions shall apply: (i) No TowerCo Work shall be commenced until all certificates, licenses, permits, authorizations, consents and approvals necessary for the TowerCo Work, from all governmental authorities having jurisdiction with respect to any Site or the TowerCo Work as set out in Section 12(c) hereof have been obtained. SBCW shall obtain, and TowerCo shall reimburse SBCW in accordance with Section 17(f) for the cost of obtaining, any FCC or FAA permits or approvals relating to TowerCo Work and all other such certificates, licenses, permits, authorizations, consents and approvals shall be obtained by TowerCo at TowerCo's cost and expense. (ii) TowerCo shall commence and perform the TowerCo Work in accordance with standard operating procedures agreed upon by the parties substantially in the form of Exhibit E attached hereto ("Standard Procedures"). (iii) TowerCo shall cause the TowerCo Work to be done and completed with industry standard materials and in a good, substantial and workmanlike manner, free from faults and defects, and in compliance with all Laws, and shall utilize only industry standard materials and supplies. TowerCo shall be solely responsible for construction means, methods, techniques, sequences and procedures, and for coordinating all activities related to the TowerCo Work, and SBCW shall have no duty or obligation to inspect the TowerCo Work, but shall have the right to do so, at reasonable times, upon reasonable prior notice and in a reasonable manner. 27 (iv) TowerCo shall promptly commence the TowerCo Work and, once commenced, diligently and continually pursue the TowerCo Work and complete the TowerCo Work within a reasonable time. TowerCo shall supervise and direct the TowerCo Work utilizing commercially reasonable efforts and reasonable care, and shall assign such qualified personnel to the TowerCo Work as may be necessary to cause the TowerCo Work to be completed in an expeditious fashion. (v) All TowerCo Work shall be performed at TowerCo's sole cost and expense. TowerCo shall provide and pay for all labor, materials, goods, supplies, equipment, appliances, tools, construction equipment and machinery and other facilities and services necessary for the proper execution and completion of the TowerCo Work. TowerCo shall promptly pay when due all costs and expenses incurred in connection with the TowerCo Work. TowerCo shall pay, or cause to be paid, all fees and taxes required by law in connection with the TowerCo Work. (vi) TowerCo shall be responsible for the acts and omissions of all of its employees, contractors, subcontractors, engineers, agents, representatives, advisors and all other persons performing any of the TowerCo Work. TowerCo shall be responsible for initiating, maintaining and supervising all necessary safety precautions and programs in connection with the TowerCo Work, and shall take all reasonable protection to prevent damage, injury or loss to, the TowerCo Work, all persons performing TowerCo Work on the Site, all other persons who may be involved in or affected by the TowerCo Work, all materials and equipment to be incorporated in the TowerCo Work, Tower and Improvements of such Site. (vii) Unless otherwise permitted to self-insure in accordance with this Sublease, TowerCo shall procure and maintain in full force and effect, and shall cause its contractors and subcontractors to procure and maintain in full force and effect, with respect to the TowerCo Work: (x) full replacement cost "all-risk", "builder's risk" insurance, insuring the TowerCo Work; and (y) the other types of insurance required to be maintained pursuant to Section 23 of this Sublease. Such additional insurance policies shall meet the requirements set forth elsewhere in this Sublease with respect to the insurance policies otherwise required to be obtained and maintained by TowerCo under this Sublease. (c) Before any TowerCo Work is performed or any antennas or other equipment are added to a Tower by TowerCo or a Space Subtenant other than SBCW and its Affiliates, TowerCo shall provide SBCW with a "Notice of TowerCo Work or Additional Equipment" in the form of Exhibit F attached hereto containing the following information with respect to any antennas or other equipment to be added and the following information, to the extent relevant with respect to any TowerCo Work to be performed, together with any additional information required 28 by Law in order for SBCW to make any necessary or appropriate FAA or FCC regulatory filings with respect thereto: Proposed temporary construction height (including any temporary equipment), Effective Radiated Power ("ERP") or Equivalent Isotropically Radiated Power ("EIRP") (if microwave); analysis of Radio Frequency ("RF") Emissions pursuant to FCC Rule 1.1307(b); statement of construction method to be used (crane, gin poke, other); description of devices installed (microwave, cellular, other (e.g. Part 15 device); specification of whether antenna is side mounted or top mounted, and if top mounted, certification that the antenna tip or other equipment is not taller than the top of the existing structure). With respect to any TowerCo Work to be performed, TowerCo also shall provide in such Notice all relevant information regarding the nature of such TowerCo Work. SBCW shall promptly make all FAA and FCC regulatory filings as it deems necessary or appropriate in connection with such addition of equipment or TowerCo Work. SBCW shall notify TowerCo promptly after the filing of any and all such FAA and FCC regulatory filings and the passage of any additional time required by any governmental entity prior to authorization to add such equipment. After receipt of such notice from SBCW, TowerCo or the Space Subtenant, as the case may be, may add such equipment to the Tower or perform such TowerCo Work, provided such addition or TowerCo Work is consistent with the information set forth in the Notice of TowerCo Work or Additional Equipment. (d) During the Term for each Site, TowerCo shall have access to the air rights over SBCW's or the applicable SBCW Affiliate's equipment shelters at such Site to install or construct a stacked equipment shelter or similar structure; provided that such stacked shelter or similar structure shall not have an adverse effect on, or interfere with, SBCW's or the applicable SBCW Affiliate's use of or access to the Site (including the Reserved Space and SBCW's Improvements at such Site). TowerCo may submit plans and specifications for stacked equipment shelters or similar structures designed for use with respect to specific types of SBCW or SBCW Affiliate equipment shelters. Provided SBCW shall have approved a particular design and the related plans and specifications, TowerCo shall have the right to install such structure(s) at appropriate Sites to which such design applies. TowerCo shall give SBCW no less than (3) three business days prior written notice of the commencement of any such installation. SECTION 13. Damage to the Site, Tower or the Improvements. (a) If there occurs a casualty which damages or destroys of all or a Substantial Portion of any Site, then either Party shall have the right to terminate this Sublease as to such Site by written notice to the other Party within thirty (30) days of the occurrence of such casualty whereupon the Term shall automatically expire as to such Site, on the date of such casualty, as if such date were the Site Expiration Date as to such Site. (b) If less than a Substantial Portion of any Site (including the Tower and Improvements thereon) is damaged or destroyed by casualty, TowerCo, at its sole cost and expense, shall promptly and diligently proceed with the adjustment of TowerCo's insurance Claims in respect thereof within a period of two (2) months after the date of the damage and, thereafter, if and to the extent required by this Section 13, promptly commence, and diligently prosecute to completion, the Restoration, repair, replacement and rebuilding of the same. The Restoration shall be carried on and completed in accordance with the provisions and conditions of this Section 13. 29 (c) All Proceeds of TowerCo's insurance shall be held by TowerCo for the mutual benefit of TowerCo and Sublessor on account of such damage, shall be applied to the payment of the costs of the Restoration and shall be paid out from time to time as the Restoration progresses. Any portion of the Proceeds of TowerCo's insurance applicable to a particular Site remaining after final payment has been made for work performed on such Site shall be retained by and be the property of Sublessor. If the cost of Restoration exceeds the Proceeds of TowerCo's insurance, TowerCo shall pay the excess cost. (d) Without limiting TowerCo's obligations hereunder in respect of a Site subject to a casualty, in the event TowerCo is required to cause the Restoration of a Site that has suffered a casualty, TowerCo shall make available to SBCW (or its Affiliate occupying space on such Site) a portion of the Subleased Property of such Site for the purpose of such Person locating a temporary communications facility, such as a "cell on wheels", and shall give such Person priority over Space Subtenants at such Site as to the use of such portion; provided, however, that: (i) the placement of such temporary communications facility does not interfere in any material respect with TowerCo's Restoration and repair of such Improvements or the operations of any Space Subtenant; (ii) such Person obtains any permits and approvals, at such Person's cost, required for the location of such temporary communications facility on such Site; and (iii) there is available space on the Site for placing such temporary communications facility. (e) The foregoing provisions of this Section 13 apply only to damage of each Site by fire, casualty or other cause occurring after the applicable Site Commencement Date. (f) If SBCW or its Affiliate damages any Site as a result of SBCW's or such Affiliate's negligent or wrongful act or omission, or failure to perform its obligations under this Sublease, SBCW or its Affiliate will, at its sole expense, promptly repair and restore the Subleased Property of such Site to its respective condition prior to such damage. (g) If TowerCo fails to complete the Restoration of the Subleased Property, of any Site required under this Sublease within two (2) months after the date of the damage, SBCW may terminate this Sublease as to the applicable Site upon giving TowerCo written notice of its election to terminate within fifteen (15) days following the expiration of such time period, provided, however, that if TowerCo's failure to complete such Restoration within such two (2)-month period is caused by: (i) failure to obtain a new permit, or (ii) TowerCo's inability to have access to the affected Site, such 2-month period shall be extended accordingly in order to allow TowerCo to complete the Restoration. (h) This Section 13(h) shall be deemed an express agreement governing any damage or destruction of any Site by fire or other casualty, and Section 227 of the Real Property Law of the State of New York providing for such a contingency in the absence of an express agreement and any other law of like import now or hereafter in force, shall have no application. SECTION 14. Space Subtenants; Interference. (a) TowerCo acknowledges and agrees that TowerCo will not permit the addition of any Space Subtenants (other than SBCW or its Affiliates in respect of any Available Space) at the Subleased Property of any Site to adversely affect SBCW's Reserved Space and its operation, use or enjoyment of any Reserved Space on such Site, taking into account customary and commercially reasonable practices for multi-tenant wireless communication sites and towers thereon. 30 (b) TowerCo shall not and shall not permit any Space Subtenants (other than SBCW or its Affiliates in respect of any Available Space) on the Subleased Property of any Site to (i) install or change, alter or improve the frequency, power, or type of the Communications Equipment that interferes with the operation of the Reserved Space of such Site or is not authorized by, or violates, any applicable Laws or is not made or installed in accordance with good engineering practices (and TowerCo shall require any Space Subtenant who subleases or licenses Available Space on any Tower to covenant to comply with the foregoing); or (ii) implement a configuration which interferes with the operation of SBCW's or its Affiliate's Communications Equipment on such Site or the Reserved Space thereof. (c) In the event any Space Subtenant installs or operates any Communications Equipment which is not authorized by, or in violation of, any Laws, TowerCo shall cause such Space Subtenant to remove such Communications Equipment promptly, failing which TowerCo shall remove such Communications Equipment. (d) In the event of any interference occurring as a result of actions of TowerCo or Space Subtenants described in Sections 14(b) above as to the Subleased Property of any Site, TowerCo shall be responsible for coordinating and resolving any such interference problems caused by TowerCo or Space Subtenants (other than SBCW or its Affiliates in respect of any Available Space), including, without limitation, using its best efforts to correct and eliminate the interference within forty-eight (48) hours of receipt of notification from SBCW and perform an interference study in accordance with the procedures set forth in Schedule 14(d). If the interference cannot be corrected or eliminated within such 48-hour period, TowerCo shall cause, at TowerCo's option, any of TowerCo's or Space Subtenants' (other than SBCW or its Affiliates in respect of any Available Space) Communications Equipment or Communications Facility that interferes with the operation of SBCW's or its Affiliate's Communications Facility or the Reserved Space, authorized frequency spectrum or signal strength, to be immediately powered down or turned off, with the right to turn such interfering equipment or facility back up or on only during off-peak hours specified by SBCW in order to determine whether such interference continues or has been eliminated; provided, however, that if any interference continues at the time the interfering equipment is powered down, the Communications Equipment that interferes with the operation of SBCW's or its Affiliates Communication Facility or Reserved Space shall be turned off. If TowerCo or any Space Subtenant (other than SBCW or its Affiliates in respect of any Available Space) cannot correct or eliminate, to the satisfaction of SBCW, such interference within twenty (20) days of receipt of written notice from SBCW, TowerCo shall or shall cause such Space Subtenant (other than SBCW or its Affiliates in respect of the Available Space) to cease the operations of the objectionable Communications Equipment and to stop providing services from the applicable Communication Facility or the Subleased Property of the applicable Site in its entirety until the interference problems are resolved. (e) SBCW and its Affiliates shall not: (1) install or change, alter or improve the frequency, power, or type of the Communications Equipment in a manner that interferes with the operation of TowerCo's or any Space Subtenant's Communications Equipment on a Site or is not authorized by Law or is not made or installed in accordance with good engineering practices; or (ii) implement a configuration which interferes with the operation of TowerCo's or any Space Subtenant's Communications Equipment on such Site. 31 (f) In the event of any interference occurring as a result of actions of SBCW or its Affiliates described in Section 14(d) above as to any Site, SBCW shall be responsible for coordinating and resolving any such interference problems caused by SBCW or its Affiliates, including, without limitation, using its best efforts to correct and eliminate the interference within forty-eight (48) hours of receipt of notification from TowerCo. If the interference cannot be corrected or eliminated within such 48-hour period, SBCW shall cause any of SBCW's or its Affiliate's Communications Equipment or Communications Facility that interferes with the operation of TowerCo's or any Space Subtenant's Communications Facility's authorized frequency spectrum or signal strength, to be immediately powered down or turned off, with the right to turn such interfering equipment or facility back up or on only during off-peak hours specified by TowerCo or the affected Space Subtenant in order to determine whether such interference continues or has been eliminated; provided, that if any interference continues at the time the interfering equipment is powered down, the Communications Equipment that interferes with the operation of TowerCo or any Space Subtenant Communication Facility shall be turned off. If SBCW or its Affiliate cannot correct or eliminate, to the satisfaction of TowerCo or the affected Space Subtenant, such interference within twenty (20) days of receipt of written notice from TowerCo, SBCW or its Affiliate shall cease the operations of the objectionable Communications Equipment and stop providing services from the applicable Communications Facility or the Subleased Property of the applicable Site in its entirety (including the Tower and Improvements) until the interference problems are resolved. (g) Notwithstanding anything in this Section 14 to the contrary, in the event any interference occurs in respect of a Site and the source of such interference is not readily determinable, it shall be assumed that TowerCo or a Space Subtenant and not SBCW or its Affiliates is the cause of such interference, TowerCo shall be responsible for the performance of its obligations under Section 14(c) in respect of such interference, and SBCW shall be relieved of any obligations under Section 14(e) in respect of such interference, unless and until it is determined that SBCW or its Affiliates is the cause of such interference. SECTION 15. Taxes and Assessments. (a) TowerCo shall pay all Taxes and Assessments with respect to each Site applicable to all periods occurring after the Site Commencement Date for such Site on or prior to the date on which such Taxes and Assessments are due; provided that TowerCo shall have the right to contest, by proper legal actions or proceedings in good faith any Taxes and Assessments for which TowerCo is responsible hereunder and, if permitted under applicable law, to defer payment of such Taxes and Assessments pending the outcome of such contest, provided that at the time of the commencement of any such action or proceeding, and during the pendency thereof, (i) no event of default by TowerCo shall have occurred and be continuing, (ii) such contest operates to suspend collection of the contested Taxes and Assessments or claims and is maintained and prosecuted continuously with diligence, (iii) the Site would not be subject to forfeiture or loss by reason of the institution or prosecution of such contest, (iv) TowerCo, shall promptly pay or discharge such Taxes and Assessments and all additional charges, 32 interest, penalties and expenses if such contest is terminated or discontinued adversely to TowerCo, and (v) TowerCo shall keep Sublessor reasonably informed of any such contest. Each Sublessor shall promptly forward to TowerCo upon receipt copies of all bills, invoices, statements, assessments and similar notices regarding Taxes and Assessments. TowerCo shall receive any refunds for Taxes and Assessments paid by TowerCo pursuant to this Sublease. Notwithstanding the foregoing, TowerCo shall not be required to pay any Taxes and Assessments payable with respect to a Leased Site if the applicable Ground Lease provides that the Ground Lessor is responsible therefor without pass-through to the ground lessee and the Ground Lessor actually pays any such Taxes and Assessments. If the Ground Lessor does not pay any such Taxes and Assessments and either Party becomes aware of it, the Parties will, at TowerCo's expense, cooperate and use commercially reasonable efforts to cause the Ground Lessor to pay such Taxes and Assessments. (b) Proration of Taxes and Assessments. In the years that include the Site Commencement Date or the Site Expiration Date of this Sublease as to any Site, any Taxes and Assessments (determined without regard to the Term) for which TowerCo is responsible to any SBCW Affiliate under this section of this Sublease and that are calculated or assessed on the basis of a time period (e.g., property Taxes assessed annually) shall be prorated proportionately by the number of days in each such period during the time period of assessment that includes the Site Commencement Date or Site Expiration Date, as the case may be. TowerCo's obligations under this Section 15 to SBCW Affiliates shall be limited to that proportionate amount of such Taxes and Assessments attributable to the period during which this Sublease is in effect with respect to such Site. SECTION 16. Utilities. TowerCo shall make all arrangements for, and thereafter shall pay, or cause to be paid, when due all charges for connection of all utilities and services to such Site for the use of Space Subtenants, including, but not limited to, electricity, telephone, power, and other utility used or consumed by Space Subtenants of such Site. As among SBCW (together with its Affiliates) and all new Space Subtenants, TowerCo shall cause utility charges to be separately metered, and SBCW or its Affiliate (as the case may be) shall be separately responsible for its own utility charges. SECTION 17. Governmental Permits. (a) In addition to and not in limitation of the provisions of Section 11(a) of this Sublease, TowerCo shall, at its own cost and expense, provide SBCW all necessary and appropriate information requested by SBCW for SBCW to obtain and maintain in effect all certificates, permits, licenses and other approvals relating to FAA or FCC regulations and TowerCo shall, at its own cost and expense, obtain and maintain in effect all certificates, permits, licenses and other approvals (other than those relating to FCC and FAA regulations) and comply with all Laws, required or imposed by governmental authorities (other than those relating to FCC or FAA regulations), in connection with the operation and maintenance of the Subleased Property of each Site (including Tower and Improvements thereon). As part of TowerCo's obligation to provide information, TowerCo shall provide SBCW access to data, including resistance changes, necessary to monitor the lighting systems at each Site. 33 (b) TowerCo shall cooperate with SBCW in SBCW's efforts to obtain and maintain in effect any certificates, permits, licenses and other approvals and to comply with any Laws required or imposed on SBCW or its Affiliates by governmental authorities, applicable to the Reserved Space of each Site. (c) SBCW shall, at its own cost and expense, obtain and maintain in effect all certificates, permits, licenses and other approvals and comply with all Laws, required or imposed by governmental authorities, in connection with operation and maintenance of the Reserved Space of each Site, including, without limitation, FCC regulations. With the cooperation of TowerCo set out in Section 17(a) hereof, SBCW, at TowerCo's cost and expense, also shall obtain and maintain in effect all certificates, permits, licenses, and other approvals required or imposed by governmental authorities in connection with FAA or FCC regulations relating to the operation and maintenance of the Subleased Property of each Site (including the Towers and Improvements thereon). The cost of obtaining and maintaining such FCC or FAA permits or approvals shall be reimbursed to SBCW in accordance with Section 17(f). (d) SBCW shall cooperate with TowerCo in TowerCo's efforts to provide required information and to comply with all Laws required or imposed by governmental authorities, applicable to each Site. (e) SBCW shall be afforded access to all of TowerCo's records, books, correspondence, instructions, blueprints, permit files, memorandum and similar data relating to the compliance of the Towers with all applicable Laws or if SBCW otherwise provides reasonable justification therefore, except privileged documents or where disclosure is prohibited by law. TowerCo shall also provide SBCW with an electronic interface or other real time access to TowerCo's Tower administration database which shall enable access to detailed information concerning collocations. Such information shall be open for inspection and copying upon reasonable notice by SBCW, at its cost, and its authorized representatives at reasonable hours at TowerCo's principal office and shall be retained by TowerCo for period of three (3) years after the expiration of this Sublease. (f) The cost of SBCW's obtaining and maintaining all FCC and FAA permits and approvals relating to the operation and maintenance of the Subleased Space and TowerCo Work shall be borne by TowerCo in accordance with Sections 12(b)(i) and 17(c) (the "Reimbursable Costs"). The Reimbursable Costs shall be based on (i) actual reasonable out-of-pocket costs and (ii) SBCW's reasonable costs allocable to obtaining and maintaining FCC and FAA permits and approvals, including personnel and office related costs allocated based on the amount of time spent by such personnel in obtaining and maintaining such permits and approvals as compared to such personnel's time spent on other matters. SBCW and TowerCo have agreed on an estimate of Reimbursable Costs (the "Estimated Cost"). SBCW shall periodically provide TowerCo with an invoice for Estimated Costs, which amount shall be paid by TowerCo to SBCW within ten (10) business days of TowerCo's receipt of such invoice. In addition, SBCW shall use its commercially reasonable efforts to deliver to TowerCo within thirty (30) days following the end of each calendar year, a statement setting forth the actual costs (based on the formula provided in subclauses (i) and (ii) above) incurred by SBCW in obtaining and maintaining such FCC and FAA permits and approvals. If actual costs are greater than Estimated Costs, TowerCo shall reimburse SBCW the difference within ten (10) Business Days of receipt of such end of the year statement. If Estimated 34 Costs are greater than actual costs, SBCW shall reimburse TowerCo for the difference at the time such end of the year statement is delivered to TowerCo. For a period of sixty (60) days after receipt by TowerCo of SBCW's annual statement setting forth actual costs, TowerCo shall have the right, at its own expense, to perform an audit of such actual costs by requesting reasonable evidence of the actual costs and expenses incurred or allocated by SBCW to Reimbursable Costs for the period in question. In addition, if the organizational structure of SBCW's FCC and FAA compliance department materially changes or the cost of obtaining and maintaining FCC and FAA permits materially changes, the parties agree to use good faith efforts to negotiate modifications to the Reimbursable Costs agreement described above and the respective responsibilities of the parties with respect to FAA and FCC compliance work. SECTION 18. No Liens. (a) TowerCo shall not create or permit any Lien (other than Permitted Liens) against any Site, or any part thereof. If any Lien (other than Permitted Liens) is filed against all or any part of any Site, TowerCo shall cause the same to be discharged by payment, satisfaction or posting of bond within thirty (30) days after TowerCo has obtained knowledge of such Lien. If TowerCo fails to cause any Lien (other than Permitted Liens) to be discharged within the permitted time, SBCW may cause it to be discharged and may pay the amount of such Lien in order to do so. If SBCW makes any such payment, all amounts paid by SBCW shall be payable by TowerCo to SBCW upon demand. "Permitted Liens" means, as to each Site: (i) Permitted Subleasehold Mortgages of TowerCo's subleasehold interest in such Site and Permitted Subleasehold Pledges; (ii) Space Subtenants' sublease interests in the Subleased Space of such Site; (iii) Liens existing on the Site Commencement Date for such Site; (iv) Liens arising by, through or under SBCW, its Affiliates or any other occupant of the Reserved Space; (v) Liens for taxes not yet due and payable or which are being contested in good faith in accordance with the provisions of Section 15; (vi) Liens created by the underlying fee owners of the Leased Sites; (vii) easements, rights of way and similar encumbrances provided that such encumbrances do not have a material adverse effect on the use or enjoyment of such Site or the Reserved Space and are approved by SBCW, such approval not to be unreasonably withheld or delayed; and (viii) mechanics' liens for amounts which are not more than thirty (30) days overdue. (b) TowerCo may, at TowerCo's sole cost and expense, in its own name and on its own behalf or in the name of and on behalf of the Sublessor, in good faith, contest any claim of Lien and, in the event of any such contest, may permit such claim of Lien so contested to remain unpaid, unsatisfied and undischarged during the period of such contest and any appeal therefrom; provided, however, that, if any Site, the Subleased Property of any Site or any part thereof are subject to imminent danger of loss or forfeiture by virtue of or by reason of such claim of Lien, such claim of Lien shall be complied with forthwith or TowerCo shall deposit with the Sublessor a sum of money reasonably required by the Sublessor as security to protect the Subleased Property of such Site from any such loss or forfeiture. The Sublessor, at the sole cost and expense of TowerCo, shall cooperate fully with TowerCo in any such contest. (c) Any Permitted Subleasehold Mortgage or Permitted Subleasehold Pledge shall be subject to each and every term, covenant, condition, agreement, requirement, restriction and provision set forth in this Sublease and subject to all rights, title and interest of SBCW and each SBCW Affiliate. 35 (d) Within ten (10) days after the granting of any Permitted Subleasehold Mortgage or Permitted Subleasehold Pledge, TowerCo shall deliver to SBCW a true, correct and fully executed copy of all documents pertaining thereto and the indebtedness secured thereby. Promptly upon TowerCo's receipt of copies of recorded documents evidencing the recordation thereof and bearing the recording information therefor, TowerCo shall deliver to SBCW a copy of such recorded documents. (e) The Sublessor shall execute any necessary easement or right of way for utilities for any Site promptly following any request by TowerCo, provided such easement or right of way does not have an adverse effect on SBCW's or its Affiliate's use or enjoyment of the Reserved Space of such Site or on the ownership by the Sublessor of the Tower on such Site, including without limitation the operation of SBCW's Communications Equipment thereon. (f) Other than as provided in Section 21, SBCW shall not create or permit any Lien against the Subleased Property of any Site, or any part thereof. If any Lien is filed against all or any part of the Subleased Property of any Site, SBCW shall cause the same to be discharged by payment, satisfaction or posting of bond within thirty (30) days after demand therefor by TowerCo. If SBCW fails to cause any Lien to be discharged within the permitted time, TowerCo may cause it to be discharged and may pay the amount of such Lien in order to do so. If TowerCo makes any such payment, all amounts paid by TowerCo shall be payable by SBCW to TowerCo upon demand. Nothing in this Sublease shall prohibit SBCW or an SBCW Affiliate from permitting a Lien against its interest under the Ground Lease or Reserved Space of any Site subject to (i) the restrictions on Transfer set forth in Section 25 and (ii) SBCW's obligations pursuant to Section 35(e) hereof in the event TowerCo exercises its right to acquire all or portion of the Sites. Notwithstanding the foregoing, any Lien against SBCW's interest under the Ground Lease shall only be permitted if such Lien is either subject to and subordinate to this Sublease and the purchase option contained herein or such lienholder executes an NDA substantially similar to the NDA provided for in Section 21. (g) SBCW may, at SBCW's sole cost and expense, in its own name and on its own behalf or in the name of and on behalf of TowerCo, in good faith, contest any claim of Lien and, in the event of any such contest, may permit such claim of Lien so contested to remain unpaid, unsatisfied and undischarged during the period of such contest and any appeal therefrom; provided, however, that, if the Subleased Property of any Site or any part thereof are subject to imminent danger of loss or forfeiture by virtue of or by reason of such claim of Lien, such claim of Lien shall be complied with forthwith or SBCW shall deposit with TowerCo a sum of money reasonably required by TowerCo as security to protect TowerCo's interest in the Subleased Property of such Site from any such loss or forfeiture. TowerCo, at the sole cost and expense of SBCW, shall cooperate fully with SBCW in any such contest. SECTION 19. Condemnation. (a) If there occurs a Taking of all or a Substantial Portion of any Site, other than a Taking for temporary use, then either Party shall have the right to terminate this Sublease as to such Site by written notice to the other Party within thirty (30) days of the occurrence of such Taking whereupon the Term shall automatically expire as to such Site, on the Date of Taking, as if such date were the Site Expiration Date as to such Site. 36 (b) If there occurs a Taking of less than a Substantial Portion of any Site, then this Sublease and all duties and obligations of TowerCo under this Sublease in respect of such Site shall remain unmodified, unaffected and in full force and effect. TowerCo shall promptly proceed to reconstruct, restore and repair the remaining portion of the Subleased Property of such Site (to the extent feasible) to a condition substantially equivalent to the condition thereof prior to the Taking. TowerCo shall be entitled to apply the Award received by TowerCo to the reconstruction, Restoration and repair of any Subleased Property of any Site from time to time as such work progresses. If the cost of the repair work exceeds the Award recovered by TowerCo, TowerCo shall pay the excess cost. If the Award exceeds the cost of the repair work, the excess shall be paid to the Sublessor. (c) If there occurs a Taking of any Subleased Property of any Site or any portion thereof, for temporary use, then this Sublease shall remain in full force and effect as to such Site for the remainder of the then current term; provided, however, that during such time as TowerCo shall be out of possession of such Subleased Property by reason of such Taking, the failure to keep, observe, perform, satisfy and comply with those terms and conditions of this Sublease compliance with which are effectively impractical or impossible as a result of TowerCo's being out of possession of such Subleased Property shall not be an event of default hereunder. The Award for any such temporary Taking payable for any period prior to the Site Expiration Date shall be paid to TowerCo and, for any period thereafter, to the Sublessor. SECTION 20. Waiver of Subrogation; Indemnity. (a) Except as provided in this Sublease, to the extent permitted by applicable Laws, TowerCo and SBCW hereby waive any and all rights of recovery, claim, action or cause of action against each other, their respective agents, officers and employees, for any loss or damage that may occur to the Subleased Property of each Site, by reason of fire, the elements, or any other cause insured against, or required to be insured against, under the terms of policies of insurance maintained, or required to be maintained, for the Subleased Property of such Site, by TowerCo or SBCW (as the case may be) under the terms of this Sublease, regardless of cause or origin. (b) Subject to the provisions of Section 20(a) above, TowerCo agrees to indemnify and to hold each SBCW Indemnitee harmless from any and all Claims, with respect to bodily injury, personal injury or property damage suffered or incurred by such SBCW Indemnitee by reason of, or arising out of TowerCo's sublease or lease, as the case may be, operation and maintenance of each Site (including the Tower and Improvements thereon), including, without limitation: (i) any default, breach, performance or nonperformance by TowerCo of its respective obligations and covenants under this Sublease, including, without limitation, Sections 12, 14 and 17, hereof; (ii) any Claims against any SBCW Indemnitee arising out of or resulting from (x) TowerCo's use, operation, maintenance or occupancy of any part of the Site or resulting from the condition of the Site or (y) any Space Subtenant's use, operation, maintenance or occupancy of its Communications Facility; (iii) any failure of TowerCo to comply with any applicable Laws or with the directives of FCC and FAA that TowerCo is required to comply with pursuant to this Sublease or under applicable Laws; (iv) any Claims arising out of or resulting from TowerCo's or any Space Subtenant's acts or omissions or the negligence or intentional acts or omissions of any of their respective agents, employees, engineers, contractors, subcontractors, 37 licensees, or invitees in or about the Subleased Property of each Site, and (v) any other provision of this Sublease which provides that TowerCo shall indemnify and hold harmless any SBCW Indemnitee in respect of the matters contained in such provision. If any action or proceeding is brought against any SBCW Indemnitee by reason of any such Claim, TowerCo upon notice from such SBCW Indemnitee covenants and agrees to defend such action or proceeding at its expense. (c) Subject to the provisions of Section 20(a) above, SBCW agrees to indemnify and to hold each TowerCo Indemnitee harmless from any and all Claims with respect to bodily injury, personal injury or property damage suffered or incurred by TowerCo by reason of, or arising out of (i) any default, breach, performance or nonperformance of SBCW's obligations and covenants under this Sublease; (ii) any Claims against TowerCo arising out of or resulting from SBCW's use, operation, maintenance or occupancy of SBCW's Communications Equipment or the Reserved Space, to the extent TowerCo is not responsible therefor under the terms of this Sublease, (iii) SBCW's failure to comply with any applicable Laws or with the directives of FCC and FAA as to SBCW's Communications Equipment; (iv) any Claims against TowerCo arising out of or resulting from any acts or omissions or the negligence or intentional actions or omissions of any of SBCW's agents, employees, engineers, contractors, subcontractors, licensees or invitees; and (v) any other provision of this Sublease which provides that SBCW shall indemnify and hold harmless TowerCo or any Affiliate thereof in respect of the matters contained in such provision. If any action or proceeding is brought against TowerCo by reason of any such Claim, SBCW upon notice from TowerCo covenants and agrees to defend such action or proceeding at its expense. SECTION 21. Subordination and Attornment. (a) This Sublease and all rights of TowerCo therein, and all interest or estate of TowerCo in the Subleased Property of each Site, or any portion thereof, shall be subordinate to any and all Mortgages, which at any time during the Term, may be placed upon the Subleased Property, or any portion thereof, by SBCW or any SBCW Affiliate, and to any replacements, renewals, amendments, modifications, extensions or refinancing thereof, and to each and every advance made under any Mortgage; provided, however, that the subordination and attornment contained herein shall not be effective unless the existing or any future Mortgagee thereunder shall execute and deliver an NDA in favor of TowerCo, in form reasonable satisfactory to TowerCo and its lenders providing that: (i) such Mortgagee will at all times fully recognize TowerCo's rights under this Sublease, including the purchase option contained herein, and in the event of a foreclosure under any such Mortgage shall not disturb TowerCo's possession of the Subleased Property and will recognize such purchase option, so long as no event of default shall have occurred and be subsisting hereunder, and so long as TowerCo shall attorn to the purchaser upon such foreclosure; and (ii) that upon Mortgagee acquiring title to the Subleased Property, TowerCo shall attorn directly to such Mortgagee. TowerCo shall agree to such other terms and conditions in the NDA as may be reasonably required by such Mortgagee, provided that such terms and conditions do not affect TowerCo's rights, nor increase or alter any of TowerCo's obligations, under this Sublease. (b) Subject to the provision of Section 21(a), TowerCo shall execute in a timely manner instruments that may be required to evidence this subordination clause, in respect of the Subleased Property of each Site. 38 (c) The applicable Sublessor shall enter into a subordination, non-disturbance and attornment agreement with any Space Subtenants at such Space Subtenant's request. Such agreement shall be in form reasonably satisfactory to the applicable Sublessor and the applicable Space Subtenant and shall provide, among other things, that Sublessor shall not terminate such Space Subtenant's subleasehold interest in the applicable Site by reason of TowerCo's default hereunder or the early termination of this Sublease due to a default by TowerCo or otherwise, so long as the Space Subtenant is not in default in the performance of the terms, provisions and conditions contained in the applicable sublease beyond notice and grace. SECTION 22. Environmental Covenants. (a) For purposes of this Sublease, the following terms shall have the following meanings: (i) "Hazardous Material" or "Hazardous Materials" means and includes petroleum products, flammable explosives, radioactive materials, asbestos or any material containing asbestos, polychlorinated biphenyls, or any hazardous, toxic or dangerous waste, substance or material defined as such or defined as a hazardous substance or any similar term, by, in or for the purposes of the Environmental Laws, including, without limitation Section 101(14) of CERCLA (hereinafter defined); provided that the term "Hazardous Materials" shall exclude quantities of materials or substances maintained by SBCW, its Affiliates, TowerCo and Space Subtenants on or about any Site (including Tower and Improvements thereon) in the ordinary course of business, so long as such materials are maintained in accordance with the applicable Environmental Laws: (ii) "Release" shall have the meaning given such term, or any similar term, in the Environmental Laws, including, without limitation Section 101(22) of CERCLA; and (iii) "Environmental Law" or "Environmental Laws" shall mean any "Super Fund" or "Super Lien" law, or any other federal, state or local statute, law, ordinance, code, rule, regulation, order or decree, regulating, relating to or imposing liability or standards of conduct concerning any Hazardous Materials as may now or at any time hereafter be in effect, including, without limitation, the following, as same may be amended or replaced from time to time, and all regulations promulgated thereunder or in connection therewith: the Superfund Amendments and Reauthorization Act of 1986 ("SARA"); The Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"); The Clean Air Act ("CAA"); the Clean Water Act ("CWA"); The Toxic Substances Control Act ("TSCA"); The Solid Waste Disposal Act ("SWDA"), as amended by the Resource Conversation and Recovery Act ("RCRA"); the Hazardous Materials Transportation Act: and the Occupational Safety and Health Act of 1970 ("OSHA"). (b) As to each Site, SBCW represents and warrants to TowerCo that, as of the Site Commencement Date for such Site, (i) to the best of SBCW's knowledge, no portion of the Land of such Site is used for the storage, processing, treatment or disposal of Hazardous Materials, except as set forth in any environmental report heretofore delivered to TowerCo; (ii) to the best of SBCW's knowledge except for such deminimus quantities that would not trigger a reporting or remediation obligation under any applicable Environmental Law, no Hazardous Materials have been released, introduced, spilled, discharged or disposed of, nor has there been a threat of release, introduction, spill, discharge or disposal of a Hazardous Materials, on, in, or under the Land of such Site, except as set forth in any environmental report heretofore delivered to TowerCo; (iii) to the best of SBCW's knowledge, there are no pending Claims, 39 administrative proceedings, judgments, declarations, or orders, whether actual or threatened, relating to the presence of Hazardous Materials on, in or under the Land of such Site; (iv) to the best of SBCW's knowledge, the Land of such Site is in compliance with all applicable Environmental Laws; and (v) to the best of SBCW's knowledge, there are no pending or threatened or contemplated condemnation actions involving all or any portion of the Land of such Site. For purposes of this Section, "to the best knowledge of," or words of similar import with reference to SBCW means actual knowledge of the management of SBCW and such actual knowledge will be imputed to the management of SBCW if the Hazardous Materials were brought to the Site by a SBCW Group Member. (c) Except for any matters for which SBCW assumes responsibility pursuant to this Sublease, TowerCo covenants and agrees that: (i) TowerCo shall not conduct or allow to be conducted upon any Site any business operations or activities, or employ or use a Site, to generate, manufacture, refine, transport, treat, store, handle, dispose of, transfer, produce, or process Hazardous Materials; provided that TowerCo shall have the right to bring, use and keep and allow any Space Subtenant to bring and keep on the Subleased Property of each Site in compliance with all applicable Laws, batteries, generators and associated fuel tanks and other substances commonly used in the industry necessary for the operation and maintenance of each Site; (ii) TowerCo shall carry on its business and operations at each Site in compliance in all respects with, and will remain in compliance with, all applicable Environmental Laws and shall require all Space Subtenants to do the same: (iii) TowerCo shall not create or permit to be created any Lien against any Site for the costs of any response, removal or remedial action or clean-up of Hazardous Materials; (iv) TowerCo shall promptly conduct and complete all investigations, studies, sampling and testing, and all remedial, removal, and other actions necessary to clean up and remove all Hazardous Materials on, from or affecting each Site in accordance with all applicable Environmental Laws; (v) TowerCo shall promptly notify SBCW in writing if TowerCo receives any notice, letter, citation, order, warning, complaint, claim or demand that: (w) TowerCo or any Space Subtenant has violated, or is about to violate, any Environmental Law, (x) there has been a Release or there is a threat of Release, of Hazardous Materials at or from the applicable Site, (y) TowerCo or any Space Subtenant may be or is liable, in whole or in part, for the costs of cleaning up, remediating, removing or responding to a Release of Hazardous Materials, or (z) a Site are subject to a Lien favor of any governmental entity for any liability, cost or damages under any Environmental Law. (d) SBCW covenants and agrees that as to each Site: (i) SBCW shall not conduct or allow to be conducted upon any Reserved Space of any Site any business operations or activities, or employ or use a Reserved Space of any Site, to generate, manufacture, refine, transport, treat, store, handle, dispose of, transfer, produce, or process Hazardous Materials; provided that SBCW shall have the right to bring, use and keep on the Reserved Space of any Site in compliance with all applicable Laws, batteries, generators and associated fuel tanks and other substances commonly used in the industry necessary for the operation and maintenance of each Reserved Space of any Site; (ii) SBCW shall carry on its business and operations on the Reserved Space of any Site in compliance in all respects with, and will remain in compliance with, all applicable Environmental Laws; (iii) SBCW shall not create or permit to be created any Lien against any Reserved Space of any Site for the costs of any response, removal or remedial action or clean-up of Hazardous Materials; (iv) SBCW shall promptly conduct and complete all investigations, studies, sampling and testing, and all remedial, 40 removal, and other actions necessary to clean up and remove all Hazardous Materials on, from or affecting the Reserved Space of each Site in accordance with all applicable Environmental Laws; (v) SBCW shall promptly notify TowerCo in writing if SBCW receives any notice, letter, citation, order, warning, complaint, claim or demand that: (w) SBCW has violated, or is about to violate, any Environmental Law, (x) there has been a Release or there is a threat of Release, of Hazardous Materials at or from the Reserved Space of any Site, (y) SBCW may be or is liable, in whole or in part, for the costs of cleaning up, remediating, removing or responding to a Release of Hazardous Materials, or (z) the Reserved Space of any Site is subject to a Lien in favor of any governmental entity for any liability, cost or damages under any Environmental Law. SBCW further covenants and agrees that the covenants contained in this Section 22(d) and the indemnifications provided for in Section 22(f) shall also apply with respect to any operations or activities of SBCW conducted upon space at a Site other than the Reserved Space. (e) Unless resulting or arising solely from the negligent or willful acts or omissions of SBCW or SBCW's Affiliates, employees, agents, engineers, contractors, subcontractors, licensees or invitees, or from any other acts or omissions of such parties in violation of this Sublease, TowerCo agrees to indemnify and hold SBCW and SBCW Affiliates harmless from and against any and all Claims, including Claims of any and every kind whatsoever paid, incurred, suffered by, or asserted against SBCW or SBCW Affiliates or the Site for, with respect to, or as a result of the following: (i) the presence in, on, over or under, or the escape, seepage, leakage, spillage, discharge, emission or Release on or from the Site of any Hazardous Materials prior to the applicable Site Expiration Date or earlier date of termination of this Sublease; (ii) the violation of any Environmental Laws relating to or affecting the Site prior to the applicable Site Expiration Date or earlier date of termination of this Sublease; (iii) a Release of any Hazardous Materials or the violation of any of the Environmental Laws prior to the applicable Site Expiration Date or earlier date of termination of this Sublease in connection with any other property owned, operated or used by or on behalf of TowerCo, which violation or Release gives or may give rise to any rights whatsoever in any Party with respect to the Site by virtue of any of the Environmental Laws; (iv) any warranty or representation made by TowerCo in this Section 22 is or becomes false or untrue in any material respect; or (v) the violation or breach of, or the failure of TowerCo to fully and completely keep, observe, satisfy, perform and comply with, any agreement, term, covenant, condition, requirement, provision or restriction of this Section 22. (f) Unless resulting or arising from the negligent or willful acts or omissions of TowerCo or TowerCo's employees, agents, engineers, contractors, subcontractors, licensees or invitees, or from any other acts or omissions of such parties in violation of this Sublease, SBCW agrees to indemnify and hold TowerCo harmless from and against any and all Claims, including Claims of any and every kind whatsoever paid, incurred, suffered by, or asserted against TowerCo or the Reserved Space of any Site for, with respect to, or as a result of the following: (i) the presence in, on, over or under, or the escape, seepage, leakage, spillage, discharge, emission or Release on or from the Reserved Space of any Site of any Hazardous Materials prior to the applicable Site Expiration Date or earlier date of termination of this Sublease; (ii) the violation of any Environmental Laws relating to or affecting the Reserved Space of any Site prior to the applicable Site Expiration Date or earlier date of termination of this Sublease; (iii) a Release of any Hazardous Materials or the 41 violation of any of the Environmental Laws prior to the applicable Site Expiration Date or earlier date of termination of this Sublease in connection with any other property owned, operated or used by or on behalf of SBCW, which violation or Release gives or may give rise to any rights whatsoever in any Party with respect to the Reserved Space of any Site by virtue of any of the Environmental Laws; (iv) any warranty or representation made by SBCW in this Section 22 is or becomes false or untrue in any material respect; or (v) the violation or breach of, or the failure of SBCW to fully and completely keep, observe, satisfy, perform and comply with, any agreement, term, covenant, condition, requirement, provision or restriction of this Section 22. (g) Notwithstanding anything to the contrary in this Sublease, in the event any Claim of a type giving rise to indemnification obligations under Section 22 is asserted against a TowerCo Indemnitee and it cannot be readily determined that it was the act or omission of SBCW or its Affiliate that gave rise to such Claim, it shall be assumed for all purposes hereof that it was TowerCo's or a Space Subtenant's act or omission, TowerCo shall indemnify SBCW Indemnitees in respect of such Claim pursuant to Section 22(e), and SBCW shall have no obligation or liability to any TowerCo Indemnitee in respect of such Claim unless and until it is finally determined that SBCW's or its Affiliate's act or omission gave rise to such Claim. The provisions of this Section 22 shall survive the applicable Site Expiration Date or earlier termination of this Sublease. The foregoing provisions of this Section 22 are not intended to limit the generality of any of the other provisions of this Sublease. SECTION 23. Insurance. (a) SBCW shall procure, and shall maintain in full force and effect at all times during the Term as to the Sites, the following types of insurance with respect to the Reserved Space of the Sites, and, if applicable, any of the Available Space subleased to SBCW or its Affiliates pursuant to Section 24(d), paying as the same become due all premiums therefor: (i) commercial general public liability insurance insuring against all liability of SBCW and SBCW's officers, employees, agents, licensees and invitees arising out of, by reason of or in connection with the use or occupancy of the Reserved Space of the Sites and, if applicable, any of the Available Space subleased to SBCW or its Affiliates pursuant to Section 24(d), if any, in an amount of not less than $1,000,000 for bodily injury or property damage as a result of one occurrence, and not less than $2,000,000 for bodily injury or property damage in the aggregate; (ii) umbrella or excess liability insurance with limits not less than $5,000,000 per occurrence and in the aggregate: and (iii) workers' compensation insurance covering all employees of SBCW or its Affiliates to the extent required by any Laws. (b) SBCW shall pay all premiums for the insurance coverage which SBCW is required to procure and maintain under this Sublease. Each insurance policy: (i) shall name TowerCo as an additional insured; provided that such requirement shall only apply to liability policy and shall have no application to workers' compensation policies; and (ii) shall provide that the policy cannot be canceled 42 as to TowerCo except after the insurer endeavors to give TowerCo thirty (30) days' written notice of cancellation. TowerCo agrees that SBCW may, at SBCW's option and election self insure with respect to all or a portion of the risks required to be insured against by SBCW under this Section 23. If SBCW elects to be covered by and participate in its self insurance and risk management programs, SBCW shall notify TowerCo of such election. From time to time, upon reasonable request by TowerCo, SBCW shall furnish to TowerCo the information concerning its risk management and self insurance policies and programs in effect at the time of such request. (c) For each Site, TowerCo shall procure, and shall maintain in full force and effect at all times during the Term as to the applicable Site, the following types of insurance with respect to each Site, including the Tower and Improvements thereon, paying as the same become due all premiums therefor: (i) commercial general public liability insurance insuring against all liability of TowerCo and TowerCo's officers, employees, agents, licensees and invitees arising out of, by reason of or in connection with the use, occupancy or maintenance of each Subleased Property (including Tower and the Improvements), in an amount of not less than $1,000,000 for bodily injury or property damage or as a result of one occurrence, and not less than $2,000,000 for bodily injury or property damage in the aggregate. (ii) umbrella or excess liability insurance with limits not less than $5,000,000 per occurrence and in the aggregate; and (iii) Insurance in an amount not less than full replacement cost of the Tower and Improvements of each Site, against direct and indirect loss or damage by fire and all other casualties and risks covered under "All Risk" insurance; and (iv) workers' compensation insurance covering all employees of TowerCo or its Affiliates to the extent required by any Laws. (d) TowerCo shall pay all premiums for the insurance coverage which TowerCo is required to procure and maintain under this Sublease. Each insurance policy (i) shall name SBCW and the applicable Sublessor as additional insureds; provided that such requirement shall only apply to liability policy and shall have no application to workers' compensation policies; and (ii) shall provide that the policy cannot be canceled as to SBCW and the applicable Sublessor except after the insurer gives SBCW ten (10) days' written notice of cancellation. If TowerCo elects to be covered by and participate in its self insurance and risk management programs, TowerCo shall notify SBCW of such election. From time to time, upon reasonable request by SBCW, TowerCo shall furnish to SBCW the information concerning its risk management and self insurance policies and programs in effect at the time of such request. (e) All policy amounts set forth in this Section 23 shall be reset every five (5) years during the Term to increase by an amount not less than the CPI Change over the five (5) year period, except to the extent the Parties otherwise agree. 43 (f) TowerCo and SBCW shall not, on their own initiative or pursuant to request or requirement of any Space Subtenants or other Person, take out separate insurance concurrent in form or contributing in the event of loss with that required in Section 23(c), unless the other Party thereto is named therein as an additional insured. The Parties agree that, all policies of insurance required by this Section 23 may contain such loss retention provisions or deductibles as is reasonable in light of financial conditions of the Parties from time to time. In addition and notwithstanding anything to the contrary contained in this Section 23(c), TowerCo shall be permitted to satisfy its obligations under Section (c)(iii) hereof by self-insuring such risk coverage to the extent reasonable in light of the financial condition of TowerCo from time to time. TowerCo and SBCW shall immediately notify the other Party hereto whenever any such separate insurance is taken out and shall deliver to SBCW original certificates evidencing the same. (g) As to the Subleased Property and Reserved Space of each Site, all policies of insurance shall be written on companies rated A:VII by AM Best or a comparable rating and licensed in the State where such Site is located. Certificates evidencing insurance shall be in a form reasonably acceptable to the recipient Party, shall be delivered to such Party upon commencement of the Term and prior to expiration of such policy, new certificates evidencing such insurance, shall be delivered to such Party not less than twenty (20) days prior to the expiration of the then current policy term. The Parties agree that all policies of insurance required by this Section 23 may contain such loss retention provisions or deductibles as is reasonable in light of financial conditions of the Parties. (h) Nothing in this Section 23 shall prevent SBCW or TowerCo from obtaining insurance of the kind and in the amount provided for under this Section 23 under a blanket insurance policy or policies (evidence thereof reasonably satisfactory to the other Party shall be delivered to the other Party by the insuring Party) which may cover other properties owned or operated by the insuring Party as well as the Subleased Property or the Available Space; provided, however, that any such policy of blanket insurance shall: (i) specify the amounts thereof to the extent such amounts are used to meet the initial limits required pursuant to this Section 23; and (ii) provide that such policies of blanket insurance shall, as respects the Subleased Property or Reserved Space of each Site, contain the various provisions required of such an insurance policy by the foregoing provisions of this Section 23. SECTION 24. Right of Substitution; Right of First Refusal. (a) Notwithstanding anything to the contrary contained herein, SBCW shall have the right (for the benefit of itself or any SBCW Affiliate) to modify and/or replace, at SBCW's expense, its Communications Equipment at any Site provided said replacement Communications Equipment does not increase the weight or sail area of SBCW's Communications Equipment (excluding the microwave dishes) on the Tower as of the date hereof by more than ten percent (10%) and otherwise does not cause overall Tower capacity to be exceeded. SBCW also shall have the right to make any Alterations to the Site that it reasonably deems necessary to increase the capacity of or otherwise augment, strengthen or enhance a Tower (a "Sublessor Alteration"). Except with respect to replacement or substitution of identical or substantially identical equipment in the identical space, the following provisions shall apply with respect to any modification, expansion, 44 replacement, addition or relocation of Communications Equipment by SBCW (in each case, an "SBCW Alteration") and any Sublessor Alteration under this Sublease. (i) Prior to commencing any such SBCW Alteration or Sublessor Alteration, SBCW shall obtain TowerCo's written approval (which approval shall not be unreasonably withheld, conditioned or delayed, so long as such modifications or replacements do not violate the applicable provisions of this Sublease) of detailed plans and specifications accurately describing the proposed SBCW Alteration or Sublessor Alteration. TowerCo shall either approve or disapprove such plans and specifications in writing within ten (10) business days of TowerCo's receipt of such plans and specifications failing which TowerCo shall be deemed to have approved SBCW's' proposed plans and specifications. (ii) SBCW agrees to comply with the reasonable directions and requirements which TowerCo, in its good faith discretion, may from time to time establish in connection with such modifications, expansions, replacements, additions and relocations or Sublessor Alterations, as the case may be, provided that such directions and requirements do not (i) unreasonably interfere with SBCW's ordinary course of business or operations, or (ii) derogate or diminish any rights of SBCW or any SBCW Affiliate under this Sublease. Such requirements may include, at TowerCo's request, the preparation, at SBCW's cost and by a professional engineer licensed in the state in which the Site is located and reasonably satisfactory to TowerCo, of a structural analysis which details the effect of the SBCW Alteration on the Tower or the Sublessor Alteration, as the case may be and TowerCo's operations. (b) Notwithstanding anything to the contrary contained herein, if during the Term, there is any Available Space in respect of the Subleased Property of any Site, then SBCW shall have the Right of Substitution (for the benefit of itself or any SBCW Affiliate) as to such Available Space. The Right of Substitution pursuant to this Section 24(b) may be exercised by SBCW at any time, and from time to time, without limit, upon written notice to TowerCo, provided that no such relocation shall impair the structural integrity of the Tower. If SBCW elects to exercise its Right of Substitution, then, upon completion of the relocation of the Communications Equipment of SBCW or its Affiliate on the Tower and Improvements thereon, the previously existing Reserved Space of the applicable Site shall automatically be released by SBCW or its Affiliate and become a part of the Subleased Property of such Site, subject to the terms of this Sublease, and concurrently therewith, the Available Space on such Site to which the Communications Equipment of SBCW or its Affiliate has been relocated shall automatically become and constitute the Reserved Space of such Site subject to Section 5. The terms of this Section 24(b) shall be self-operative, and no further instrument shall be required to evidence any Substitution; provided, however, that upon the request of either SBCW or TowerCo, the Parties shall promptly execute such instruments as may be reasonably required to further evidence such Substitution, including without limitation an amendment to Exhibit A or the applicable Site Designation Supplement. SBCW or its Affiliate shall, at such Person's cost and expense, complete the relocation of its Communications Equipment and return the previously existing Reserved Space to its original condition, ordinary wear and tear excepted. 45 (c) Notwithstanding anything to the contrary contained herein, if during the Term, TowerCo intends to sublease any Available Space of the Subleased Property of any Site to a potential Space Subtenant, TowerCo shall notify SBCW and Sublessor by sending a copy of any letter-offer, letter of intent, or other correspondence with the potential Space Subtenant together with a summary of the economic terms of the proposed sublease as contained in such documents, which economic terms shall include at least the number and location of all Sites subject to the proposed lease or sublease, the number, type, and location of each antenna or other equipment on each Tower, the rent payable for such antenna or other equipment on the Tower (including any escalation provisions), and the term of each Space Subtenant sublease and any renewals thereof, which term in no event shall bind Sublessor to a term (including renewals) which extends beyond the Site Expiration Outside Date of the Site in question unless Sublessor shall have consented to such extended term in writing, such consent not to be unreasonably withheld or delayed (the "Economic Offer"). SBCW may, in its sole discretion, by providing written notice thereof to TowerCo within ten (10) days after receipt of the Economic Offer from TowerCo (x) exercise its Right of Substitution pursuant to Section 24(b) in respect of such Available Space, or (y) exercise the Right of First Refusal in respect of such Available Space pursuant to Sections 24(e) and (f), or (z) exercise both, if with respect to multiple Sites. If TowerCo intends to sublease Available Space at multiple Sites, SBCW shall not be entitled to exercise either its Right of Substitution and/or its Right of First Refusal as to any Available Space unless SBCW exercises such Right in respect of a minimum of the greater of (i) five percent (5%) or (ii) two (2) of the total number of Sites that TowerCo intends to sublease. (d) If SBCW exercises the Right of Substitution as to any Available Space, then such Available Space shall become "Reserved Space" for all purposes of this Sublease and be subject to the provisions of Section 5. If SBCW exercises the Right of First Refusal as to such Available Space, then TowerCo shall sublease the Available Space to SBCW (or its designated Affiliate) for the sublease term set forth in the applicable Economic Offer. For the first three hundred (300) times that SBCW exercises its Right of First Refusal pursuant to this Section 24, the rent for such space shall be equal to the lesser of (i) the rent provided for in the Economic Offer or (ii) an amount of rent that bears the same proportion to the SBCW Leaseback Charge charged with respect to the Site(s) at which such Available Space is located as the Available Space with respect to which SBCW exercises the Right of First Refusal bears to the Reserved Space of such Site(s). With respect to any exercise by SBCW of its Right of First Refusal after the first three hundred (300) times, the rent for any additional space leased pursuant to such exercise of the Right of First Refusal shall be the amount specified in the Economic Offer. SBCW (or its designated Affiliate) and TowerCo shall execute a sublease agreement in the form substantially similar to the BTS Sublease (as defined in the Build-to-Suit Agreement), as modified to reflect the rental rate as herein above provided for and the sublease term in the applicable Economic Offer, or in any other form acceptable to TowerCo and SBCW and, SBCW shall, for all purposes of this Sublease, become a Space Subtenant of such Available Space at the rate prescribed above. (e) If SBCW fails to notify TowerCo as to its election to exercise its Right of Substitution or its Right of First Refusal under Section 24(c), then SBCW's options referred to in Section 24(c) with respect to such Available Space shall expire and TowerCo shall be entitled to sublease such Available Space to the potential Space Subtenant within 90 days after SBCW's receipt of the Economic Offer (which ninety (90) day period shall be extended so long as TowerCo is 46 diligently endeavoring to conclude such sublease) upon, in all material respects, the terms and conditions contained in the applicable Economic Offer. (f) If TowerCo subleases any Available Space of any Site to the potential Space Subtenant as provided above, TowerCo shall promptly provide SBCW a copy of the final definitive sublease with the Space Subtenant (the "Final Agreement"). If the economic terms of the Final Agreement are not the same or better for TowerCo, in all material respects, than those of the Economic Offer, then, in addition to any other remedies SBCW may have, SBCW may require that the SBCW Leaseback Charge for the Site in question and all other economic terms be reduced to and conformed with those of the Final Agreement. (g) If such Available Space has not been so subleased to such Space Subtenant within 90 days after SBCW's receipt of the applicable Economic Offer (which ninety (90) day period shall be extended so long as TowerCo is diligently endeavoring to conclude such sublease), then the restrictions provided in this Section 24 shall again apply with respect to such Available Space, and TowerCo shall have no right to sublease any such Available Space without again offering such Available Space to SBCW in accordance with the provisions of this Section 24. SECTION 25. Assignment and Subletting. (a) Without the prior written consent of SBCW, TowerCo may not assign this Sublease or any of TowerCo's rights hereunder in whole or in part except that (A) TowerCo may assign all of its rights under this Sublease, without SBCW's consent, to any parent, subsidiary or Affiliate of TowerCo; (B) TowerCo may sublease Available Space as provided in Section 24 hereof; and (C) TowerCo may, with SBCW's consent not to be unreasonably withheld (provided that such consent will not be required in the case of a transaction described in Clause (A)), assign this Sublease in its entirety to a successor corporation or entity to TowerCo by way of merger, consolidation or other reorganization or to any Person acquiring all or substantially all of TowerCo's assets; provided that in the case of an assignment under Subsection (A) such assignee (i) is not a SBCW Competitor and (ii) assumes all of TowerCo's obligations hereunder; and in the case of an assignment under Subsection (C) such assignee (i) is a Permitted TowerCo Transferee, (ii) is not a SBCW Competitor and (iii) assumes all of TowerCo's obligations hereunder; provided further that TowerCo may make a partial assignment of this Sublease upon the prior written consent of SBCW to be provided in its sole and absolute discretion. Upon any permitted assignment under (A) or (C) , TowerCo shall be released from its obligations under this Sublease from and after the date of such assignment. Upon any permitted assignment under Subsection (C) above (other than to any parent, subsidiary or Affiliate of TowerCo), TowerCo Parent shall, with SBCW's written consent not to be unreasonably withheld, be released from its obligations under this Sublease from and after the date of such assignment. Notwithstanding the foregoing, TowerCo may enter into Permitted Subleasehold Pledges and Permitted Subleasehold Mortgages, in which case the Permitted Subleasehold Collateral Assignee with respect thereto shall have the right to exercise remedies under any such mortgage, pledge, hypothecation or other collateral transfer in a manner consistent with the provisions of this and every other agreement between TowerCo and SBCW made in connection with this transaction. TowerCo acknowledges that it shall not be permitted to enter into a Permitted Subleasehold Mortgage with respect to all or any portion of a Site prior to the Closing of such Site in accordance with Section 4.1 of the Agreement to Sublease. 47 (b) SBCW and each Sublessor Entity shall have the unrestricted right during the Term, subject to any required consent of any Ground Lessor, to sell, convey, transfer, assign or otherwise dispose (but not to sublease) of SBCW's or such Sublessor Entity's interest in and to any Site (including SBCW's or a SBCW Affiliate's interest in and to the Subleased Property of such Site), in whole or in part (a "Transfer") to: (i) a SBCW Affiliate; (ii) a Permitted Transferee; or (iii) any other Person (a "Non-Qualifying Transferee"); provided, however, that with respect to subsections (ii) and (iii) above, neither SBCW or such Sublessor Entity may assign its interest in the Reserved Space except in connection with the sale or other transfer of all or a portion of SBCW's wireless business on a Site by Site basis, and provided further that SBCW may not assign its interest in the Reserved Space without transferring the corresponding Ground Lease, and vice versa. In the event of any Transfer by SBCW or a SBCW Affiliate to a Non-Qualifying Transferee, SBCW shall not be relieved of its obligations hereunder. In the event of any other Transfer by SBCW or a SBCW Affiliate, all obligations under this Sublease of the Person effecting such Transfer shall cease and terminate with respect to the Site in question and TowerCo shall look only and solely to the Person to whom SBCW's or such SBCW Affiliate's interest in and to such Site (including SBCW's or such SBCW Affiliate's interest in and to the Subleased Property thereof or any portion thereof) (a "Transferee") is Transferred for performance of all of SBCW's or such Affiliate's duties and obligations under this Sublease with respect to such Site (provided that the Transferee assumes all of SBCW's or such Affiliate's obligations hereunder). Notwithstanding the foregoing, in the event of a Transfer by SBCW or a SBCW Affiliate to a Non-Qualifying Transferee, if either (x) such Non-Qualifying Transferee ultimately becomes a Permitted Transferee or (y) subject to the consent of TowerCo, which consent may not be unreasonably withheld, no unwaived event of default on the part of such Non-Qualifying Transferee occurs in respect of such Sites for three (3) years after the date of such Transfer to such Transferee, SBCW or such SBCW Affiliate, as applicable, shall be released from any and all obligations under this Sublease as to such Sites, pursuant to Section 25(c), and upon SBCW's request TowerCo shall confirm such release in writing. Except as expressly provided in Section 25(b), wherever under or in connection with this Sublease SBCW or any SBCW Affiliate assigns its right, title or interest, in whole or in part, in or to this Sublease or any Site, SBCW or such SBCW Affiliate shall be released from performing any and all obligations under this Sublease in respect of the right, title or interest so assigned and under the applicable Ground Lease, from and after the date of such assignment, and TowerCo hereby acknowledges such release. At or prior to any partial assignment of this Sublease, SBCW or SBCW Affiliate and such assignee shall have entered into one or more agreements, including without limitation, a sublease and site designation supplements (collectively, the "New Sublease Documents"), that afford SBCW and such SBCW Affiliate relative rights (including, without limitation, provisions relating to the right of SBCW to act for TowerCo), vis-a-vis SBCW's or such SBCW Affiliate's rights and obligations under the New Sublease Documents no less favorable to SBCW and SBCW Affiliates than those afforded by the Sublease and the Site Designation Supplements with respect to the rights and obligation of SBCW and any SBCW Affiliate, and are otherwise in form and substance reasonably satisfactory to SBCW. 48 (c) Without limiting the generality of the other provisions of this Sublease, any assignment of interest pursuant to this Sublease shall be effectuated by ten (10) days' written notice of such assignment, which notice shall include the name, address, and telephone number of assignee. Each Party hereby agrees that any attempt of the other Party to assign its interest in this Sublease or any of its rights hereunder, in whole or in part, in violation of Section 25 shall constitute a default under this Sublease and shall be null and void ab initio (d) In the event that a Ground Lease restricts TowerCo's ability to sublease space on the Leased Property, the applicable Sublessor agrees that it shall use commercially reasonable efforts to assist and cooperate with TowerCo in obtaining any such necessary consents, at TowerCo's sole cost and expense, from the Ground Lessor. SECTION 26. Estoppel Certificate. Either Party, from time to time upon ten (10) days' prior request by the other Party, shall execute, acknowledge and deliver to the requesting Party, or to a person designated by such requesting Party, a certificate stating that this Sublease is unmodified and in full effect (or, if there have been modifications, that this Sublease is in full effect as modified, and setting forth such modifications) and the dates to which Rent and other sums payable under this Sublease have been paid, and either stating that to the knowledge of the signer of such certificate no default exists hereunder or specifying each such default of which the signer has knowledge. The requesting Party, at such Party's cost and expense, shall cause such certificate to be prepared for execution by the requested Party. Any such certificate may be relied upon by any prospective Permitted Collateral Assignee, Mortgagee or purchaser of the Subleased Property of each Site. SECTION 27. Holding Over. If TowerCo remains in possession of the Subleased Property of any Site after expiration or termination of the then current Term as to such Site without any express written agreement by SBCW, then TowerCo shall be and become a tenant at sufferance, and there shall be no renewal or extension of this Sublease by operation of law. This section shall be deemed to be an "agreement expressly providing otherwise" within the meaning of Section 232-c of the Real Property law of the State of New York. SECTION 28. Rights of Entry and Inspection. (a) TowerCo shall permit SBCW and SBCW's representatives, agents and employees to enter the Subleased Property of any Site at all reasonable times for the purposes of inspecting such Subleased Property, showing the Site to prospective purchasers, tenants and Mortgagees, making any repairs or replacements or performing any maintenance, and performing any work on the Site that SBCW may consider necessary to prevent or cure deterioration, waste or unsafe conditions. Nothing in this Section 28 shall imply or impose any duty or obligation upon SBCW to enter upon any Site at any time for any purpose, or to inspect the Subleased Property at any time, or to perform, or pay the cost of, any work which TowerCo is required to perform under any provision of this Sublease, and SBCW has no such duty or obligation. 49 (b) SBCW shall permit TowerCo and TowerCo's representatives to inspect SBCW's Communications Equipment for the purpose, in the event of an Emergency only, for making repairs or replacements to address such Emergency. The foregoing shall not limit TowerCo's rights pursuant to Section 7 hereof. SECTION 29. A Party's Right to Act for the Other Party; SBCW Set-Off Right. (a) In addition to and not in limitation of any other remedy SBCW may have under this Sublease, if TowerCo fails to make any payment or to take any other action (or to cause any Space Subtenant to take any action) when and as required under this Sublease, including without limitation Sections 11(a) and 17 and Exhibit C, SBCW may, without demand upon TowerCo and without waiving or releasing TowerCo from any duty, obligation or liability under this Sublease, make any such payment or take any such other action required of TowerCo. Unless TowerCo's failure results in or relates to an Emergency, SBCW shall give TowerCo at least ten (10) days prior written notice of SBCW's intended action and TowerCo shall have the right to cure such failure within such 10-day period. No such notice shall be required in the event of an Emergency. The actions which SBCW may take shall include, but are not limited to, the performance of maintenance or repairs and the making of replacements to the Towers and Improvements on each Site (and SBCW shall have full access to the Sites for such purpose), the payment of insurance premiums which TowerCo is required to pay under this Sublease, the payment of Ground Rents which TowerCo is required to pay under the Ground Leases and the payment of Taxes and Assessments which TowerCo is required to pay under this Sublease. SBCW may pay all incidental costs and expenses incurred in exercising its rights hereunder, including, without limitation, reasonable attorneys' fees and expenses, penalties, re-instatement fees, late charges, and interest. An amount equal to one hundred twenty percent (120%) of the total amount of the costs and expenses (including salaries and benefits of employees) incurred by SBCW or SBCW's Affiliates in accordance with this Section 29, is referred to as the "Reimbursable Maintenance Expenses" of SBCW, shall be due and payable by TowerCo upon demand and bear interest at the rate of eighteen percent (18%) per annum from the date of demand until paid by TowerCo. SBCW shall have the right to set off against any SBCW Leaseback Charges due under Section 10 hereof the amount of any Reimbursable Maintenance Expenses and any other amounts due and owing by TowerCo or TowerCo Parent to SBCW or any SBCW Affiliates hereunder. (b) For purposes of this Section, the term "Emergency" means any event that causes, has caused or is likely to cause, (i) any bodily injury, personal injury or property damage; (ii) the suspension, revocation, termination or any other adverse material effect as to any licenses and/or permits; (iii) any adverse effect on the ability of SBCW or its Affiliates or any Space Subtenants to operate Communications Equipment; or (iv) any failure of any Site to comply in any material respect with applicable Laws. SECTION 30. Defaults and Remedies. (a) The following events shall constitute events of default by SBCW: (i) If SBCW or a SBCW Affiliate fails to perform any material obligations pursuant to the applicable Ground Lease for a Site that SBCW or a SBCW Affiliate is expressly required to perform pursuant to the terms of 50 this Sublease and shall not cure such failure by the later of (x) the expiration of any applicable cure period, or (y) thirty (30) days after TowerCo gives SBCW written notice thereof; or (ii) if SBCW shall materially violate or breach, or shall materially fail to fully and completely observe, keep, satisfy, perform and comply with, any agreement, term, covenant, condition, requirement, restriction or provision of this Sublease in respect of any Site (which violations, breaches or failures may be different for each Site), and shall not cure such violation, breach or failure within thirty (30) days after TowerCo gives SBCW written notice thereof, or, if such failure shall be incapable of cure within thirty (30) days, if SBCW shall not commence to cure such failure within such thirty (30) day period and continuously prosecute the performance of the same to completion with due diligence; or (iii) Subject to Section 30(i), SBCW breached any material representation or warranty in this Sublease as to any Site as of the date when made. (iv) if SBCW becomes insolvent as defined in the Uniform Commercial Code under the Laws applicable to this Sublease or makes an assignment for the benefit of creditors; or if any action is brought by SBCW seeking its dissolution or liquidation of its assets or seeking the appointment of a trustee, interim trustee, receiver or other custodian for any of its property; or if SBCW commences a voluntary proceeding under the Federal Bankruptcy Code; or if any reorganization or arrangement proceeding is instituted by SBCW for the settlement, readjustment, composition or extension of any of its debts upon any terms; or if any action or petition is otherwise brought by SBCW seeking similar relief or alleging that it is insolvent or unable to pay its debts as they mature; or if any action is brought against SBCW seeking its dissolution or liquidation of any of its assets, or seeking the appointment of a trustee, interim trustee, receiver or other custodian for any of its property, and any such action is consented to or acquiesced in by SBCW or is not dismissed within ninety (90) days after the date upon which it was instituted; or if any proceeding under the Federal Bankruptcy Code is instituted against SBCW and (1) an order for relief is entered in such proceeding, or (2) such proceeding is consented to or acquiesced in by SBCW or is not dismissed within ninety (90) days after the date upon which it was instituted; or if any reorganization or arrangement proceeding is instituted against SBCW for the settlement, readjustment, composition or extension of any of its debts upon any terms, and such proceeding is consented to or acquiesced in by SBCW or is not dismissed within ninety (90) days after the date upon which it was instituted; or if any action or petition is otherwise brought against SBCW seeking similar relief or alleging that it is insolvent, unable to pay its debts as they mature or generally not paying its debts as they become due, and such action or petition is consented to or acquiesced in by SBCW or is not dismissed within thirty (30) days after the date upon which it was brought. (b) Upon the occurrence of any event of default by SBCW under Section 30(a)(iv), TowerCo may terminate this Sublease by giving SBCW written notice of termination, and this Sublease shall be terminated at the time designated by TowerCo in its notice of termination to SBCW whereupon SBCW shall be obligated to refund to TowerCo all Rent for the rental periods occurring after the 51 effective date of such termination. Upon the occurrence of any event of default by SBCW under Sections 30(a)(i)-(a)(iii) as to the Reserved Space of a Site, TowerCo may terminate this Sublease as to such Site by giving SBCW written notice of termination, and this Sublease shall be terminated as to the applicable Site at the time designated by TowerCo in its notice of termination to SBCW whereupon SBCW shall be obligated to refund to TowerCo the Rent allocable to such Site for the rental periods occurring after the effective date of such termination. Notwithstanding the foregoing, if SBCW fails to pay any portion of a SBCW Leaseback Charge because SBCW or a SBCW Affiliate, acting in good faith, reduced the amount of SBCW Leaseback Charges paid to TowerCo in giving effect to a mistaken belief that it made Reimbursable Maintenance Expenses under Section 29(a) that SBCW or a SBCW Affiliate was not permitted to make, such failure shall not constitute an event of default hereunder. Upon TowerCo's demand after any resolution of any dispute as to the amount of such Reimbursable Maintenance Expenses, SBCW shall pay such amount to TowerCo, with interest thereon at the rate of eighteen percent (18%) per annum, from the date such amount was due until the date paid. (c) TowerCo's remedy stated in Section 29(b) above shall not preclude pursuit of any other remedy or remedies provided in this Sublease or any other remedy or remedies provided for or allowed by law or in equity, separately or concurrently or in any combination. (d) The following events shall constitute events of default by TowerCo: (i) If TowerCo fails to timely pay Ground Rent as provided in Section 3(d) or otherwise fails to make payment of any amount due hereunder and such failure continues for ten (10) days after the date such payment was due and payable or, with respect to the payment of Ground Rent, for such longer grace period as may be provided for in the applicable Ground Lease, or (ii) (x) TowerCo shall materially violate or breach, or shall materially fail to fully and completely observe, keep, satisfy, perform and comply with, any term, covenant, condition, requirement, restriction or provision of this Sublease with respect to any Site (which violations, breaches or failures may be different for each Site), and shall not cure such violation, breach or failure within thirty (30) days after SBCW gives TowerCo written notice thereof, or, if such failure can be cured, but not within thirty (30) days, if TowerCo shall not commence to cure such failure within such thirty (30) day period and continuously prosecute the performance of the same to completion with due diligence or (y) the aggregate amount of Reimbursable Maintenance Expenses in respect of any Site pursuant to Section 29(a) exceeds $4,000 on at least two occurrences within the same Sublease Year, whether or not reimbursed by TowerCo; or (iii) Subject to Section 30(i), any representation or warranty made by TowerCo in this Sublease shall be false or misleading in any material respect on the date as of which made (or deemed made); or (iv) TowerCo or TowerCo Parent shall materially violate or breach, or shall materially fail to fully and completely observe, keep, satisfy or perform any obligation for money borrowed involving not less than $5,000,000 in principal 52 amount in connection with this Sublease, including, without limitation, Mortgages, or any obligation under notes payable or drafts accepted, or any obligation of any other agreement, term or condition contained in any indenture or agreement under which any such obligation is created, guaranteed or secured if the effect of such default is to cause such obligation to become due prior to its stated maturity; or (v) If TowerCo becomes insolvent as defined in the Uniform Commercial Code under the Laws applicable to this Sublease or any Site or makes an assignment for the benefit of creditors; or if any action is brought by TowerCo seeking its dissolution or liquidation of its assets or seeking the appointment of a trustee, interim trustee, receiver or other custodian for any of its property; or if TowerCo commences a voluntary proceeding under the Federal Bankruptcy Code; or if any reorganization or arrangement proceeding is instituted by TowerCo for the settlement, readjustment, composition or extension of any of its debts upon any terms; or if any action or petition is otherwise brought by TowerCo seeking similar relief or alleging that it is insolvent or unable to pay its debts as they mature; or if any action is brought against TowerCo seeking its dissolution or liquidation of any of its assets, or seeking the appointment of a trustee, interim trustee, receiver or other custodian for any of its property, and any such action is consented to or acquiesced in by TowerCo or is not dismissed within ninety (90) days after the date upon which it was instituted; or if any proceeding under the Federal Bankruptcy Code is instituted against TowerCo and (1) an order for relief is entered in such proceeding, or (2) such proceeding is consented to or acquiesced in by TowerCo or is not dismissed within ninety (90) days after the date upon which it was instituted; or if any reorganization or arrangement proceeding is instituted against TowerCo for the settlement, readjustment, composition or extension of any of its debts upon any terms, and such proceeding is consented to or acquiesced in by TowerCo or is not dismissed within ninety (90) days after the date upon which it was instituted; or if any action or petition is otherwise brought against TowerCo seeking similar relief or alleging that it is insolvent, unable to pay its debts as they mature or generally not paying its debts as they become due, and such action or petition is consented to or acquiesced in by TowerCo or is not dismissed within thirty (30) days after the date upon which it was brought. (e) Upon the occurrence of any event of default by TowerCo under Section 30(d), Section 14(c), Section 14(d) or Section 11(c) in respect of any Site, SBCW may terminate this Sublease as to the applicable Site by giving TowerCo written notice of termination, and this Sublease shall be terminated as to such Site, at the time designated by SBCW in its notice of termination to TowerCo, unless otherwise provided herein. Upon the occurrence of events of default (whether of the same or different types) by TowerCo under Section 30(d) in respect of more than fifty (50) Sites during any consecutive five (5) year period or portion thereof, SBCW may terminate this Sublease as to all Sites by giving TowerCo written notice of termination, and this Sublease shall be terminated as to all Sites at the time designated by SBCW in its notice of termination to TowerCo. (f) SBCW and each Sublessor may pursue any remedy or remedies provided in this Sublease, including without limitation Section 30(e), or any remedy or remedies provided for or allowed by law or in equity, separately or concurrently or in any combination, including, without limitation, (i) specific performance or 53 other equitable remedies; (ii) money damages arising out of such default; (iii) SBCW may exercise the Withdrawal Right as to any Site immediately and without further act, pursuant to Section 9; or (iv) SBCW may perform, on behalf of TowerCo, TowerCo's obligations under the terms of this Sublease pursuant to Section 29, in which event SBCW shall have the right to set off all Reimbursable Maintenance Expenses against the SBCW Leaseback Charges SBCW is required to pay. If the amount of Reimbursable Maintenance Expenses exceeds the SBCW Leaseback Charges payable by SBCW hereunder and TowerCo does not reimburse SBCW the full amount of such excess within ten (10) days following SBCW's written demand therefor, SBCW may terminate this Sublease in respect of all or any of the Sites pursuant to Section 30(e) and shall be reimbursed thereof. (g) A Party's pursuit of any one or more of the remedies provided in this Sublease shall not constitute an election of remedies excluding the election of another remedy or other remedies, or a forfeiture or waiver of any amounts payable under this Sublease as to the applicable Site by such Party or waiver of any relief or damages or other sums accruing to such Party by reason of the other Party's failure to fully and completely keep, observe, perform, satisfy and comply with all of the agreements, terms, covenants, conditions, requirements, provisions and restrictions of this Sublease. Notwithstanding anything to the contrary contained herein, neither Party shall be liable to the other parties for indirect, incidental, special or consequential damages, including but not limited to lost profits, however arising, even if a Party has been advised of the possibility of such damages. (h) Either Party's forbearance in pursuing or exercising one or more of its remedies shall not be deemed or construed to constitute a waiver of any event of default or of any remedy. No waiver by either Party of any right or remedy on one occasion shall be construed as a waiver of that right or remedy on any subsequent occasion or as a waiver of any other right or remedy then or thereafter existing. No failure of either Party to pursue or exercise any of its powers, rights or remedies or to insist upon strict and exact compliance by the other Party with any agreement, term, covenant, condition, requirement, provision or restriction of this Sublease, and no custom or practice at variance with the terms of this Sublease, shall constitute a waiver by either Party of the right to demand strict and exact compliance with the terms and conditions of this Sublease. (i) Notwithstanding the foregoing, no event of default shall be deemed to have occurred in respect of SBCW under Section 30(a)(iii) or in respect of TowerCo under Section 30(d)(iii), if the other Party gives notice after one (1) year following: (i) the applicable Site Commencement Date with respect to the Site in question in the case of a representation or warranty made under this Sublease or the applicable Site Designation Supplement, as to any Site; (ii) the date hereof, in the case of any other representation or warranty made under this Sublease; or (iii) in the case of representation or warranty made under the Agreement to Sublease, as provided therein. 54 (j) Upon the occurrence of any event of default by TowerCo under this Section 30 in respect of any Site, the applicable Sublessor shall give every Permitted Subleasehold Collateral Assignee of which Sublessor has written notice a written notice of, and an opportunity to cure within forty-five (45) days after receipt of such Sublessor's written notice of default, all existing defaults hereunder. In the event the Permitted Subleasehold Collateral Assignee fails to cure defaults as to any Site within such forty-five (45) day period, such Sublessor may terminate this Agreement as to such Site. The parties hereto agree that prior to the date upon which such Sublessor has the right to terminate this Agreement as to such Site, any Permitted Subleasehold Collateral Assignee may, at its option, be substituted and replace TowerCo as Sublessee hereunder (and TowerCo agrees to relinquish all rights hereunder) by assuming and agreeing to be bound by each and every term, covenant, condition, agreement, requirement, restriction and provision set forth in this Agreement, and subject to all rights, title, and interest of the applicable Sublessor; provided that in the event there have been more than fifty (50) events of default within any five (5) year period and SBCW gives notice under Section 30(d) hereof of its election to terminate this Sublease, such Permitted Subleasehold Collateral Assignee may, prior to termination of this Agreement by the applicable Sublessor, transfer its interests under this Agreement in its entirety after providing evidence satisfactory to SBCW that the proposed assignee is not an SBCW Competitor and has appropriate industry experience, the capability and the financial ability to perform the obligations of TowerCo hereunder and under any other agreements relating to or concerning the transactions between SBCW and TowerCo. SECTION 31. Quiet Enjoyment. TowerCo shall, subject to the terms and conditions of this Sublease, peaceably and quietly hold and enjoy the Subleased Property of each Site during the Term without hindrance or interruption from SBCW, so long as no event of default has occurred and is continuing hereunder. SECTION 32. No Merger. There shall be no merger of this Sublease or the subleasehold interest or estate created by this Sublease in any Site with the superior estate held by the Sublessor thereof, by reason of the fact that the same person or entity may acquire, own or hold, directly or indirectly, both the subleasehold interest or estate created by this Sublease in any Site and such superior estate; and this Sublease shall not be terminated, in whole or as to any Site, except as expressly provided herein. SECTION 33. Broker and Commission. (a) All negotiations in connection with this Sublease have been conducted by and between TowerCo and SBCW without the intervention of any person or other Party as agent or broker other than Goldman, Sachs & Co. which is advising SBCW's parent, SBC Communications Inc., in connection with this Sublease and related transactions. (b) TowerCo and SBCW warrant and represent to each other that there are no broker's commissions or fees payable in connection with this Sublease by reason of their respective dealings, negotiations or communications other than the advisor's fee payable to Goldman, Sachs & Co. which shall be payable by SBC 55 Communications Inc. TowerCo and SBCW shall, and do hereby indemnify, defend and hold harmless each other from and against the Claims of any and all brokers, agents and other intermediaries alleging a commission, fee or other payment to be owing by reason of their respective dealings, negotiations or communications in connection with this Sublease. SECTION 34. Recording of Site Designation Supplement. (a) Subject to the applicable provisions of the Agreement to Sublease, upon the execution of this Sublease, TowerCo may, at its cost and expense (i) cause the Ground Leases or memorandum of Ground Leases for the Sites to be filed in the appropriate County property records, unless such Ground Leases expressly prohibit such recording; and (ii) promptly following the execution of each Site Designation Supplement, cause such Site Designation Supplement to be filed in the appropriate County property records unless the Ground Lease for the applicable Site prohibits such recording. (b) In addition to and not in limitation of any other provision of this Sublease, the Parties shall have the right to review and make corrections, if necessary, to any and all exhibits hereto or to the Site Designation Supplements after the date hereof. After making such corrections, TowerCo shall re-record any such Site Designation Supplements to reflect such corrections, if requested by either Party. The Parties shall cooperate with each other to cause changes to be made in the documentation for any Site, and in the Site Designation Supplement for such Site, if such changes are requested by either Party to evidence any permitted changes in the description of the Reserved Space respecting such Site, including, without limitation changes in SBCW's or such SBCW Affiliate's antennas or other parts of its Communications Facility at such Site. In addition to and not in limitation of the foregoing, either Party shall have the right, at its sole expense, to cause any amendment to a Site Designation Supplement to be recorded, including without limitation in connection with such changes. SECTION 35. Purchase Options. (a) Right to Purchase. If this Sublease shall not have been earlier terminated, or an event of default by TowerCo shall not have occurred and be continuing at the date of option exercise or the date fixed for purchase (as such date is specified below), TowerCo shall have an option, exercisable no earlier than one hundred eighty (180) days and no later than one hundred twenty (120) days prior to each Site Expiration Outside Date (the "Option Trigger Window") to elect to purchase all (but not less than all) of the Sites then subleased under this Sublease which have the same Site Expiration Outside Date, at a purchase price equal to the aggregate of the Option Purchase Price Amounts and any additional amounts determined pursuant to Section 3(i) hereof for the applicable Sites and on the other terms and subject to the conditions herein specified. TowerCo may exercise such purchase option by submitting to SBCW in writing an offer for all of such Sites within the Option Trigger Window. The applicable Sublessors shall be obligated to sell, and TowerCo shall be obligated to buy, all such Sites at a closing to be effective as of the relevant Site Expiration Outside Date. SBCW shall use commercially reasonable efforts to obtain all consents to TowerCo's purchase of Leased Sites pursuant to this Section 35 that may be required by the Ground Leases encumbering such Sites. In the event that SBCW cannot obtain such consents on or prior to the closing date determined pursuant to Section 35(b), 56 then SBCW shall, at TowerCo's option, enter into alternative arrangements mutually acceptable to SBCW and TowerCo which do not violate the terms of the applicable Ground Leases and which provide TowerCo with rights and benefits comparable to those afforded by an assignment. Except as provided in this Section 35, TowerCo shall have no right or option to purchase the Sites subject to this Sublease. (b) Payment of the Purchase Price. TowerCo shall pay to SBCW (as agent for the applicable Sublessors) the Option Purchase Price Amounts and any additional amounts determined pursuant to Section 3(i) hereof for the applicable Sites in cash or immediately available funds on or prior to the closing of such sale. At the closing of such sale, SBCW shall transfer the purchased Sites, at TowerCo's expense, to TowerCo and the Term as to such Sites shall end. Risk of loss for the Sites purchased pursuant to Section 35 shall pass from the applicable Sublessor(s) to TowerCo upon payment of the purchase price therefor. This Sublease shall remain in full force and effect with respect to Sites subject to TowerCo's binding election under Section 35(a) until the applicable Site Expiration Outside Date. (c) Transfer by SBCW. Any transfer of Sites by SBCW or any SBCW Affiliate to TowerCo pursuant to this Section 35 shall include: (i) an assignment of Sublessor's interest in any Ground Lease for such Site, a transfer of fee simple title to the Land for any Site which is an Owned Site, a transfer of Sublessor's interest in the applicable Tower and related assets (other than SBCW Improvements, including SBCW's current or future Communications Equipment) and all appurtenances thereto; provided that for so long as the Ground Lease, as amended, modified, or extended, is still in effect, SBCW or any SBCW Affiliate shall be entitled to continue to lease the Reserved Space on each such Site from TowerCo for successive 1 year terms at rental rate equal to the lesser of the then current market rental rates for comparable locations as mutually agreed to by SBCW and TowerCo on an annual basis prior to the commencement of each lease year or the Leaseback Charge then being charged, provided that the Leaseback Charge shall thereafter be subject to increase on an annual basis at the beginning of each 1-year term in an amount equal to the CPI Change; provided, further however, if TowerCo and SBCW fail to agree on a rental rate for one or more of the Sites, such rental rate shall be determined for each applicable Site by Ernst & Young or another nationally recognized independent accounting firm mutually acceptable to SBCW and TowerCo. The cost of the determination of the rental rate shall be shared equally by SBCW and TowerCo. SBCW shall have the right to elect to terminate any such lease with respect to a Site as of the expiration of each annual term by giving no less than sixty (60) days prior written notice of such termination to TowerCo; (ii) to the extent legally transferable, all rights of SBCW or any Sublessor under or pursuant to warranties, representations and guarantees made by suppliers or manufacturers in connection with such Site, but excluding any rights to receive amounts under such warranties, representations and guarantees representing reimbursements for items paid by SBCW or a Sublessor; and (iii) to the extent legally transferable, all known and unknown rights, claims, credits, causes of action, or rights to commence any causes of action or rights of setoff of SBCW or a Sublessor against third parties relating to such Site 57 arising on or after the date of transfer, including unliquidated rights under manufacturers' and vendors' warranties, but excluding all amounts representing reimbursements for items paid by SBCW or a Sublessor. (d) Evidence of Transfer. The Sublessor and TowerCo shall enter into assignments, deeds (with warranties of title as to Sublessor's actions only), bills of sale and such other documents and instruments as the other may reasonably request to evidence any transfer of such Sites. (e) No Warranties. Any transfer of a Site by a Sublessor or TowerCo pursuant to this Sublease shall be "AS IS" and without any warranty whatsoever by SBCW or TowerCo, except that in any transfer of a Site by a Sublessor to TowerCo pursuant to this Sublease, Sublessor shall warrant that it has not previously transferred title to such Site that is so transferred and that each such Site is free of Liens created by or through SBCW or any Affiliate thereof. SECTION 36. Net Lease. This Sublease (along with the corresponding Site Designation Supplement) is a net lease and, except as otherwise expressly provided in Sections 13 and 19 hereof, shall not terminate, nor shall TowerCo be entitled to any abatement, reduction, setoff, counterclaim, defense or deduction with respect to any Rent or other sum payable hereunder. Except as otherwise expressly provided in Sections 12 and 19 hereof, the obligation of Lessee under this Sublease or any Site Designation Supplement shall not be affected by reason of: (a) any damage to or destruction of any Site or any part thereof by any cause whatsoever; (b) any condemnation of any of the Site; (c) any prohibition, limitation, restriction or prevention of TowerCo's use or enjoyment of a Site by any person; (d) any matter affecting title to any Site or any part thereof; (e) any loss of possession by TowerCo of a Site or any portion, by reason of title paramount or otherwise; (f) the invalidity or unenforceability of any provision hereof or the impossibility or illegality of performance by SBCW or TowerCo or both; (g) any action of any federal, state, local or foreign Governmental Authority; or (h) any other cause or occurrence whatsoever, whether similar or dissimilar to the foregoing. The parties intend that the obligations of TowerCo hereunder shall continue unaffected unless such obligations shall have been modified or terminated pursuant to an express provision of this Sublease. SECTION 37. Compliance with Specific FCC Regulations. (a) TowerCo understands and acknowledges that Space Subtenants are engaged in the business of operating communications equipment, including, without limitation, Communications Equipment at each Site. The Communications Equipment is subject to the regulations of the FCC, including without limitation regulations regarding exposure by workers and members of the public to the radio frequency emissions generated by SBCW's Communications Equipment. TowerCo acknowledges that such regulations prescribe the permissible exposure levels to emissions from the Communications Equipment which can generally be met by maintaining safe distances from such Communications Equipment. In order to comply with such regulations, TowerCo shall install, or cause the Space Subtenants to install, at its or their expense, such marking, signage or barriers to restrict access to any Subleased Property of each Site as TowerCo 58 deems necessary in order to comply with the applicable FCC regulations. TowerCo further agrees to post, or to cause the Space Subtenants to post, prominent signage at all points of entry to the Subleased Property of each Site containing instructions as to any potential risk of exposure and methods for minimizing such risk. TowerCo shall cooperate in good faith with SBCW to minimize any confusion or unnecessary duplication that could result in similar signage being posted with respect to any of SBCW's transmission equipment at or near any Site in respect of any Reserved Space on such Site. (b) TowerCo further agrees to alert all personnel working at or near each Site, including TowerCo's maintenance and inspection personnel, to heed all of TowerCo's or Space Subtenant's signage or restrictions with respect to the Subleased Property of a Site, to maintain the prescribed distance from the Communications Equipment, and to otherwise follow the posted instructions. TowerCo further agrees to alert each Space Subtenant in advance of any repair or maintenance work to be performance on any Site which would require work in closer proximity to the Subleased Property than prescribed by the signage or restrictions. (c) TowerCo agrees to cooperate with each Space Subtenant on a going-forward basis with respect to each Site in order to insure that such Space Subtenant complies with the applicable FCC regulations. (d) SBCW acknowledges and agrees that its Communications Equipment at each Site is subject to the regulations of the FCC, including without limitation regulations regarding exposure by workers and members of the public to the radio frequency emissions generated by SBCW's (and its Affiliates') Communications Equipment. SBCW acknowledges that such regulations prescribe the permissible exposure levels to emissions from its Communications Equipment which can generally be met by maintaining safe distances from such Communications Equipment. SBCW shall cooperate in good faith with TowerCo to minimize any confusion or unnecessary duplication that could result in similar signage being posted with respect to any of SBCW's (and its Affiliates') transmission equipment at or near any Site in respect of any Reserved Space on such Site. (e) SBCW further agrees to alert all personnel working at or near each Site, including SBCW's maintenance and inspection personnel, to maintain the prescribed distance from the Communications Equipment, and to otherwise follow the posted instructions of TowerCo. SECTION 38. TowerCo Parent's Guaranty. (a) TowerCo Parent unconditionally guarantees to SBCW, the Sublessor Entities, the SBCW Affiliates, and each SBCW Indemnitee (collectively, the "beneficiaries", individually a "beneficiary") the full and timely payment and performance and observance of all of the terms, provisions, covenants and obligations of TowerCo under this Sublease and each Site Designation Supplement (the "Obligations"). TowerCo Parent agrees that if TowerCo defaults at any time during the Term of this Sublease and any Site Designation Supplement in the performance of any of the Obligations, TowerCo Parent shall faithfully perform and fulfill all Obligations and shall pay to the applicable beneficiary all attorneys' fees, court costs, and other expenses, costs and disbursements incurred by the applicable beneficiary on account of any default by TowerCo and on account of the enforcement of this guaranty. 59 (b) If TowerCo defaults under this Sublease or any Site Designation Supplement, and the applicable beneficiary elects to enforce the provisions of this Section 36, the applicable beneficiary shall promptly give TowerCo Parent written notice thereof, which notice shall constitute an exercise of the applicable beneficiary's rights against TowerCo Parent pursuant to this Section 36. Following the receipt of such notice by TowerCo Parent, TowerCo Parent shall have the same period of time as is afforded to TowerCo under this Sublease or the applicable Site Designation Supplement to cure such default, but no such cure period shall diminish the obligations of TowerCo Parent under this Section 36. (c) This guaranty obligation of TowerCo Parent shall be enforceable by the applicable beneficiary in an action against TowerCo Parent without the necessity of any suit, action, or proceedings by the applicable beneficiary of any kind or nature whatsoever against TowerCo, without the necessity of any notice to TowerCo Parent of TowerCo's default or breach under this Sublease or the applicable Site Designation Supplement, and without the necessity of any other notice or demand to TowerCo Parent to which TowerCo Parent might otherwise be entitled, all of which notices TowerCo Parent hereby expressly waives. TowerCo Parent hereby agrees that the validity of this guaranty and the obligations of TowerCo Parent hereunder shall not be terminated, affected, diminished, or impaired by reason of the assertion or the failure to assert by the applicable beneficiary against TowerCo any of the rights or remedies reserved to the applicable beneficiary pursuant to the provisions of this Sublease or the applicable Site Designation Supplement or any other remedy or right which the applicable beneficiary may have at law or in equity or otherwise. (d) TowerCo Parent covenants and agrees that this guaranty is an absolute, unconditional, irrevocable and continuing guaranty. The liability of TowerCo Parent hereunder shall not be affected, modified, or diminished by reason of any assignment, renewal, modification or extension of this Sublease and any Site Designation Supplement or any modification or waiver of or change in any of the covenants and terms of this Sublease or any Site Designation Supplement by agreement of a beneficiary and TowerCo, or by any unilateral action of either a beneficiary or TowerCo, or by an extension of time that may be granted by a beneficiary to TowerCo or any indulgence of any kind granted to TowerCo, or any dealings or transactions occurring between a beneficiary and TowerCo, including, without limitation, any adjustment, compromise, settlement, accord and satisfaction, or release, or any bankruptcy, insolvency, reorganization, arrangements, assignment for the benefit of creditors, receivership, or trusteeship affecting TowerCo. TowerCo Parent does hereby expressly waive any suretyship defense it may have by virtue of any statute, law, or ordinance of any state or other governmental authority. (e) All of the beneficiaries' rights and remedies under this guaranty are intended to be distinct, separate, and cumulative and no such right and remedy herein is intended to be the exclusion of or a waiver of any other. (f) TowerCo Parent hereby waives presentment, demand for performance, notice of nonperformance, protest, notice of protest, notice of dishonor, and notice of acceptance. TowerCo Parent further waives any right to require that an action be brought against TowerCo or any other person or to require that resort be had by a beneficiary to any security held by such beneficiary. 60 SECTION 39. Tax Indemnities. (a) Income Tax Indemnity. (1) Tax Assumptions. In entering into this Sublease and related documents, the SBCW Group has made the following assumptions regarding the characterization of the transactions contemplated hereunder for federal income tax purposes (the "Tax Assumptions"): (i) for federal income tax purposes, the Sublease will be treated as a "true lease" with respect to all of the Subleased Property, the members of the SBCW Group will be treated, directly or indirectly through one or more entities that are classified as partnerships or disregarded entities for federal income tax purposes, as the owners and Sublessors of the Subleased Property, and TowerCo will be treated as the lessee of the Subleased Property; (ii) following the execution of this Sublease, the SBCW Group will be entitled to deduct, pursuant to Section 168(b) of the Code, depreciation deductions with respect to the adjusted tax basis in the Subleased Property using the same depreciation method(s) as in effect immediately before the execution of this Sublease ("Federal Depreciation Deductions"); (iii) prepaid Rent will be characterized as a loan under section 467 of the Code and Treasury Regulations issued thereunder and the SBCW Group will be entitled to deduct interest attributable thereto; (iv) the only amounts that any SBCW Group Member will be required to include in gross income with respect to the transactions contemplated by this Sublease and related documents will be (A) Rent as it accrues in accordance with the terms of this Sublease and the application of Section 467 of the Code and Treasury Regulations issued thereunder; (B) any indemnity (including any gross up) pursuant to this Sublease; (C) any amounts paid or otherwise recognized pursuant to a voluntary sale or other disposition by any SBCW Group Member (other than a sale or disposition attributable to a default by TowerCo and/or the exercise of remedies by SBCW or any SBCW Affiliate under this Sublease) of any Subleased Property; and (D) proceeds upon TowerCo's exercise of the purchase option pursuant to Section 35 of this Sublease; and (v) the combined effective federal and net state income tax rate applicable to each SBCW Group Member will be 39 percent (the "Assumed Rate"), comprised of 35 percent for the assumed federal rate and 4 percent (which is net of federal income tax benefits) for the assumed state rate. (2) TowerCo's Representations and Covenants. TowerCo hereby represents and covenants to each SBCW Group Member as follows: (i) TowerCo, any Affiliate of TowerCo, any assignee or sublessee of TowerCo, and any user (other than SBCW or its Affiliates) of any portion of the Subleased Property will not claim depreciation deductions as the owner of any of the Subleased Property for federal 61 income tax purposes during the Term (and thereafter unless TowerCo purchases such property pursuant to Section 35 hereof), with respect to such Subleased Property or portion thereof, except with respect to Alterations financed by TowerCo or such assignee, sublessee, or other user, nor will they take any other action in connection with filing a Tax return or otherwise which would be inconsistent with the treatment of the SBCW Group Members as the direct or indirect owners and Sublessors of the Subleased Property for federal income tax purposes; (ii) none of the Subleased Property will constitute "tax-exempt use property" as defined in Section 168(h) of the Code as a result of the status of TowerCo or any assignee, sublessee, or user (other than SBCW or its Affiliates) of the Subleased Property; (iii) to the best of TowerCo's knowledge, on the Site Commencement Date, no Alterations to any of the Subleased Property will be required in order to render any of the Subleased Property complete for its intended use by TowerCo except for ancillary Severable Alterations that are customarily selected and furnished by lessees of property similar in nature to the Subleased Property; (iv) Except to the extent that TowerCo may make Non-Conforming Alterations pursuant to Section 3(i) hereof, TowerCo has no current plan or intention of making any Alteration or repair with respect to any of the Subleased Property that would not be treated as severable improvements or permitted nonseverable improvements within the meaning of Revenue Procedure 75-21, 1975-1 C.B. 715, or Revenue Procedure 79-48, 1979-2 C.B. 599; (v) TowerCo has no current plan or intention of making any Alteration or repair with respect to any of the Subleased Property the value of which as of the end of the Term with respect to such Subleased Property would compel TowerCo to exercise any of the purchase options under Section 35 of this Sublease; (vi) TowerCo is not obligated to exercise any of the purchase options provided in Section 35 of this Sublease, it has not decided whether it will exercise any of the purchase options provided in Section 35 of this Sublease, and it has no plans to enter into or incur such obligation or to make such decision in the immediate future; (vii) TowerCo has no reason to believe that the fair market value of any Subleased Property, determined at the end of the applicable Term (taking into account inflation or deflation), is equal to or greater than the Option Purchase Price Amount of such Subleased Property; and (viii) TowerCo believes that the Rent with respect to any Subleased Property is no greater than the fair rental value of such Subleased Property throughout the Term. (3) Indemnity for Tax Losses. 62 (i) If, as a result of (A) the inaccuracy of any representation of TowerCo, or the breach of any covenant of TowerCo, set forth in Section 39(a)(2) hereof; (B) any act of TowerCo, or any assignee or sublessee of TowerCo or any user of the Subleased Property (other than SBCW or its Affiliates) during the Term, other than any act required under the Transaction Documents; (C) the failure by TowerCo to perform any act required of it under any of the Transaction Documents; (D) the failure by TowerCo to perform any act reasonably requested by any SBCW Group Member provided that (1) such act is not inconsistent with the obligations of TowerCo and other requirements under the Transaction Documents, (2) such act does not have any adverse effect on TowerCo, and (3) such SBCW Group Member or SBCW agrees to reimburse TowerCo for all reasonable costs incurred in connection with performing such act; (E) any disposition of Subleased Property attributable to a default by TowerCo and/or the exercise of remedies under this Sublease; or (F) the bankruptcy of TowerCo, any SBCW Group Member (each a "Tax Indemnitee") shall not claim on the relevant income tax return (based upon a written opinion from independent tax counsel that there is no reasonable basis that is consistent with the standards provided for in ABA Formal Opinion 85-352 as in effect on the date hereof for claiming) all or any portion of the Federal Income Tax Benefits, shall lose the right to claim all or any portion of the Federal Income Tax Benefits, shall suffer a loss of, disallowance of, or delay in obtaining all or any portion of the Federal Income Tax Benefits, or shall be required to recapture all or any portion of the Federal Income Tax Benefits, or any Tax Indemnitee shall suffer an Inclusion (any such event being referred to as a "Tax Loss"), then, within thirty (30) days after receipt of a written demand from or on behalf of the Tax Indemnitee describing in reasonable detail the Tax Loss and the computation of the amount payable (a "Tax Indemnity Notice"), TowerCo shall pay to such Tax Indemnitee as an indemnity the amount specified in the Tax Indemnity Notice. Subject to other adjustments required by this Section 39(a)(3)(i), such indemnity payment shall be calculated in the Tax Indemnity Notice to equal, on an After-Tax Basis, the sum of (y) the amounts of any additional federal and state income taxes payable by such Tax Indemnitee for the taxable year calculated at the Assumed Rate as the result of such Tax Loss and any interest thereon (calculated to the date such payment is made using the actual interest rates for underpayments of tax applicable to the relevant periods), plus (z) the amount of any penalties and additions to tax actually payable as a result of such Tax Loss and attributable thereto. At the option of such Tax Indemnitee, the indemnity payment shall be determined on a periodic, or "pay as you go," basis, with each such payment reduced for any reduction in Taxes also calculated at the Assumed Rate resulting from any Tax benefits realized by such Tax Indemnitee as a result of the event giving rise to the indemnity payment. Alternatively, at the option of such Tax Indemnitee, the indemnity payment shall be a net lump-sum amount, taking into account all past and anticipated future Tax Losses and Tax savings at the Assumed Rate, and using a discount rate equal to the Applicable Federal Rate (as 63 defined in Code section 1274(d)(1) then in effect) to present value future Tax Losses and Tax savings. Any indemnity payment made pursuant to this Section 39(a)(3)(i) shall be made on an "After-Tax Basis" which means that any such payment shall also include a "gross-up" for any federal or state income Taxes (determined at the highest marginal applicable federal and state rates then in effect) payable by such Tax Indemnitee with respect to the receipt or accrual of such indemnity payment, including such gross-up. Notwithstanding any other provision of this Section 39(a)(3)(i) to the contrary, TowerCo shall not be required to make any payment under this Section 39(a)(3)(i) earlier than, (a) in the case of a Tax Loss that is not being contested pursuant to Section 39(d) hereof, the date such Tax Indemnitee (or the common parent of the consolidated group in which it is a member, as the case may be) files the applicable federal income Tax return, estimated or final as the case may be, which would first properly reflect the additional federal income Tax that would be due as a result of the Tax Loss and (b) in the case of a Tax Loss that is being contested pursuant to Section 39(d) hereof, thirty (30) days after the date on which a Final Determination is made (or as otherwise provided in Section 39(d)). (ii) Verification of Calculations. TowerCo may timely request that any Tax Indemnity Notice be verified by Ernst & Young or another nationally recognized independent accounting firm selected by TowerCo and reasonably acceptable to such Tax Indemnitee. Such verification shall be at TowerCo's expense unless such accounting firm determines that the amount payable by TowerCo is more than ten percent less than the amount shown on the Tax Indemnity Notice, in which event the Tax Indemnitee shall pay such costs. In order to enable such independent accountants to verify such amounts, the Tax Indemnitee shall provide to such independent accountants (for their confidential use and not to be disclosed to TowerCo or any other person) all information reasonably necessary for such verification. (4) Exceptions. Notwithstanding any provision of this Section 39(a) to the contrary, TowerCo shall not be required to make any payment to any Tax Indemnitee in respect of any Tax Loss to the extent that any such Tax Loss occurs as a result of one or more of the following events: (i) Except to the extent of any inaccuracy of a representation or breach of covenant of TowerCo in Section 39(a)(2) hereof, any act of TowerCo or any assignee or sublessee of TowerCo or any user of the Subleased Property (other than SBCW or its Affiliates) other than any act required under any of the Transaction Documents, or any failure by TowerCo to perform any act required of it under any of the Transaction Documents or any act reasonably requested by any SBCW Group Member with respect to which the three conditions in Section 39(a)(3)(i)(D) have been satisfied, a determination that the Sublease is not a "true lease" for federal income tax purposes or such Tax Indemnitee is not the owner or Sublessor of the applicable Subleased Property; (ii) Except to the extent caused by any inaccuracy of a representation or breach of covenant of TowerCo in Section 39(a)(2) hereof, any act of TowerCo or any assignee or sublessee of TowerCo or any user of the Subleased Property (other than SBCW or its Affiliates) other than any act required under any of the Transaction Documents, or any failure by TowerCo to perform any act required of it under any of the Transaction Documents or any act reasonably requested by any SBCW Group Member with respect to which the three conditions in Section 64 39(a)(3)(i)(D) have been satisfied, the voluntary sale, assignment, transfer, or other disposition or the involuntary sale, assignment, transfer, or other disposition attributable to the bankruptcy, insolvency or the breach of any covenant or obligation of the Tax Indemnitee set forth in the Transaction Documents of or by any such Tax Indemnitee, in either case, of any of the Subleased Property or portion thereof by any such Tax Indemnitee other than a sale, assignment, transfer, or disposition (A) contemplated by the Transaction Documents or otherwise; (B) otherwise resulting from the exercise by any SBCW Group Member of its rights or performance of its obligations under the Transaction Documents; or (C) attributable to a default by TowerCo and/or exercise of remedies under this Sublease; (iii) the gross negligence or willful misconduct of such Tax Indemnitee; (iv) penalties, interest, or additions to Tax to the extent based upon issues unrelated to the transactions contemplated by the Sublease and related documents; (v) the inclusion in income by any SBCW Group Member on its U.S. federal income tax return of any amount attributable to an Inclusion unless (x) such Inclusion is supported by a written opinion of independent tax counsel that there is no reasonable possibility of success in taking the position that the amount is not includable in income, or (y) such Inclusion shall be due to the failure of TowerCo timely to provide Tax Indemnitee with information reasonably available to TowerCo that is timely requested in writing by the Tax Indemnitee and necessary for the Tax Indemnitee to exclude such amounts from income; and (vi) any failure of the Tax Indemnitee to have taken all the actions, if any, required of it by Section 39(d) hereof to contest the Loss and such failure materially prejudices the ability to contest, and TowerCo has a reasonable basis for such contest (other than a failure attributable in whole or part to the failure of TowerCo to follow the procedures set forth in Section 39(d) hereof). (b) General Tax Indemnity. (1) Except as provided in Section 39(b)(2), TowerCo agrees to pay and to indemnify, protect, defend, save, and keep harmless each SBCW Group Member on an After-Tax Basis, from and against any and all taxes, impositions, fees, levies, assessments, duties, withholdings, governmental claims, or other charges of any nature whatsoever (together with any related interest, fines, penalties, or additions to tax), including without limitation, rental, income, withholding, sales, use, transfer, leasing, personal or real property, excise, receipts, franchise, value-added, stamp, filing, recording, documentation, or license taxes, however imposed or asserted, by any United States state or local government or taxing authority (all the foregoing being herein collectively called "Taxes" or, separately a "Tax", upon or with respect to (A) any of the Subleased Property, any portion thereof, or any interest therein (B) the acquisition, purchase, sale, financing, leasing, subleasing, ownership, maintenance, repair, redelivery, alteration, insuring, control, use, operation, delivery, possession, repossession, location, storage, refinancing, refund, transfer of title, registration, reregistration, transfer of registration, return, or other disposition thereof of any of the Subleased Property or any portion thereof, or interest therein, (C) the rental payments, receipts, or 65 earnings arising from the Subleased Property, any portion thereof, or any interest therein, or payable pursuant to the Sublease, or any other payment or right to receive payment pursuant to any related document, or (D) any Alteration, removal, substitution, maintenance, or repair of any of the Subleased Property. (i) Exclusions from General Tax Indemnity. The provisions of Section 39(b)(1) shall not apply to, and TowerCo shall have no liability under Section 39(b)(1) with respect to: (ii) Taxes on any SBCW Group Member (other than such Taxes that are sales, use, rental, property, stamp, document filing, license, or ad valorem Taxes, or value added Taxes that are in the nature of or in lieu of such Taxes) imposed on any such member that are franchise Taxes, privilege Taxes, doing business Taxes, or Taxes imposed on, based on or measured by, gross or net income, receipts, capital, or net worth of any such member which are imposed by any state, local, or other taxing authority within the United States or by any foreign or international taxing authority that would have been imposed without regard to the execution of this Sublease and related documents and the transactions contemplated thereunder; (iii) Taxes on any SBCW Group Member, including without limitation, sales and transfer Taxes, that result from any transfer by any SBCW Group Member of any of the Subleased Property other than a sale, assignment, transfer, or disposition (I) attributable to a default by TowerCo and/or exercise of remedies under this Sublease or related documents; (II) resulting from any maintenance, repair, Alteration, substitution, relocation, or removal of or any addition to any of the Subleased Property or portion thereof or interest therein, (III) resulting from any loss, damage, destruction, theft, taking, casualty, condemnation, confiscation, expropriation, or seizure of any Subleased Property or portion thereof or interest therein; or (IV) resulting from any subleasing, permitting use thereof, or relinquishing possession of any Subleased Property or portion thereof or interest therein; (iv) Taxes imposed by any jurisdiction on any SBCW Group Member solely as a result of its activities in such jurisdiction unrelated to the transactions contemplated by the Sublease and related documents; (v) Taxes on any SBCW Group Member that result from the willful misconduct or gross negligence of any such member or an Affiliate thereof or the inaccuracy or breach of any representation, warranty, or covenant of such Tax Indemnitee or an Affiliate thereof under the Transaction Documents (except to the extent such inaccuracy or breach is attributed to an inaccuracy or breach of any representation, warranty or covenant of TowerCo or an Affiliate under the Transaction Documents); (vi) Taxes which are attributable to any period or circumstance occurring after the expiration or earlier termination of this Sublease, except to the extent attributable to (I) a failure of TowerCo or any of its transferees or sublessees or users of the Subleased Property (other than SBCW or its Affiliates) to fully discharge its obligations under the Sublease and related documents, or (II) Taxes imposed on or with respect to any payments that are due after the expiration or earlier termination of the Sublease and which are attributable to a period or circumstance occurring prior to or simultaneously with such expiration or earlier termination; 66 (vii) any Tax that is being contested in accordance with the provisions of Section 39(d) during the pendency of such contest, but only for so long as such contest is continuing in accordance with Section 39(d) and payment is not otherwise required pursuant to Section 39(d); or (viii) Taxes imposed on any SBCW Group Member that are United States federal or state net income Taxes of any such member. The provisions of this Section 39(b)(2) shall not apply to any Taxes imposed in respect of the receipt or accrual of any payment made by TowerCo on an After-Tax Basis. (2) Reports. If any report, return, certification, or statement is required to be filed with respect to any Tax that is subject to indemnification under this Section 39(b), TowerCo shall timely prepare and file the same to the extent permitted by law (except for (i) any report, return, or statement relating to any net income Taxes or, (ii) any report, return, or statement relating to any other Taxes described in Section 39(b)(2)(i) or any Taxes in lieu of or enacted in substitution for any of the foregoing, except that, in such cases, TowerCo shall timely provide information necessary to file such report, return, or statement or (iii) any other report, return, certification, or statement which any SBCW Group Member has notified TowerCo that such member intends to prepare and file); provided that any such member shall have furnished TowerCo, at TowerCo's expense, with such information reasonably necessary to prepare and file such returns as is within such member's control. TowerCo shall either file such report, return, certification, or statement and send a copy of such report, return, certification, or statement to the member, or, where not so permitted to file, shall notify the member of such requirement within a reasonable period of time prior to the due date for filing (without regard to any applicable extensions) and prepare and deliver such report, return, certification, or statement to the member. In addition, within a reasonable time prior to the time such report, return, certification, or statement is to be filed, TowerCo shall, to the extent permitted by law, cause all billings of such Taxes to be made to each SBCW Group Member in care of TowerCo, make payment thereof, and furnish written evidence of such payment. TowerCo shall furnish promptly upon written request such data, records and documents as any SBCW Group Member may reasonably require of TowerCo to enable such member to comply with requirements of any taxing jurisdiction arising out of such member's participation in the transactions contemplated by this Sublease and related documents. (3) Payments. Any Tax indemnified under this Section 39(b) shall be paid directly when due to the applicable taxing authority if direct payment is permitted, or shall be reimbursed to the appropriate SBCW Group Member on demand if paid by such member in accordance herewith. Except as otherwise provided in this Section 39(b), all amounts payable to a SBCW Group Member hereunder shall be paid promptly in immediately available funds, but in no event later than the later of (i) ten (10) Business Days after the date of such demand or (ii) two (2) Business Days before the date the Tax to which such amount payable hereunder relates is due or is to be paid and shall be accompanied by a written statement describing in reasonable detail the Tax and the computation of the amount payable. Such written statement shall, at TowerCo's request, as long as payment is not delayed, be verified by Ernst & Young, or another nationally recognized independent accounting firm selected by such member. Such verification shall be at TowerCo's expense unless the accounting firm determines that the amount 67 payable by TowerCo is more than ten percent less than the amount shown on such written statement, in which event, the applicable SBCW Group Member shall pay such costs. In the case of a Tax subject to indemnification under this Section 39(b) which is properly subject to a contest in accordance with Section 39(d), TowerCo (i) shall be obligated to make any advances with respect to such Tax whenever required under Section 39(d) and (ii) shall pay such Tax (in the amount finally determined to be owing in such contest) on an After-Tax Basis prior to the latest time permitted by the relevant taxing authority for timely payment after a final determination. (c) Tax Savings. If, by reason of any payment made to or for the account of any Tax Indemnitee by TowerCo pursuant to Section 39(a) or 39(b), such Tax Indemnitee at any time realizes a reduction in any Taxes or receives a refund which was not taken into account previously in computing such payment by TowerCo to or for the account of the Tax Indemnitee, then the Tax Indemnitee shall pay to TowerCo an amount equal to such actual reduction in Taxes or such refund (including interest received), plus the amount of any additional reduction in Taxes of the Tax Indemnitee attributable to the payment made by the Tax Indemnitee to TowerCo pursuant to this sentence; provided, however, that (A) the Tax Indemnitee shall not be obligated to make such payment with respect to any net Tax savings or refund to the extent that the amount of such payment would exceed the excess of (x) all prior indemnity payments (excluding costs and expenses incurred with respect to contests) made by TowerCo with respect to the Tax being refunded or reduced pursuant to Section 39(a) or 39(b), as the case may be, over (y) the amount of all prior payments by the Tax Indemnitee to TowerCo hereunder with respect to such Tax provided that any such excess tax savings realized (or deemed realized) by such Tax Indemnitee which are not paid to TowerCo as a result of this subclause (A) shall be carried forward and reduce TowerCo's obligations to make subsequent payments to such Tax Indemnitee pursuant to Section 39 hereof; and (B) if any such Tax savings or refund realized by such the Tax Indemnitee, or any tax savings taken into account for purposes of determining "After-Tax Basis" shall be lost or otherwise determined to be unavailable, such lost or otherwise unavailable Tax savings or refund shall be treated as a Tax for which TowerCo must indemnify the Tax Indemnitee pursuant to Section 39(a) or 39(b), as the case may be (without regard to the exceptions in Section 39(a)(4) or 39(b) other than the Section 39(a)(4)(iii), 39(a)(4)(iv), or 39(b)(2)(iv)). (d) Contest Rights. In the event that any Tax Indemnitee receives any written notice of any potential claim or proposed adjustment against such Tax Indemnitee that would result in a Tax Loss against which TowerCo may be required to indemnify pursuant to Section 39(a) or 39(b) (a "Tax Claim"), such Tax Indemnitee shall promptly notify TowerCo thereof and provide TowerCo with relevant information thereto; provided, however, that the failure by the Tax Indemnitee to provide any such information shall not be treated as a failure to comply with this Section 39(d) unless the failure materially prejudices the conduct of the contest hereunder. TowerCo may require the Tax Indemnitee to contest such Tax Claim at TowerCo's expense and, in that event, the Tax Indemnitee shall consult with TowerCo in good faith, but the Tax Indemnitee shall retain ultimate control over such contest. Notwithstanding the immediately 68 preceding sentence, the Tax Indemnitee shall not be obligated to contest such Tax Claim unless (1) prior to taking the first such required action, TowerCo shall have furnished to the Tax Indemnitee, in the case of a contest with respect to federal income Taxes, with an opinion of a nationally recognized, independent tax counsel chosen by TowerCo and reasonably acceptable to the Tax Indemnitee, or, in the case of a contest with respect to other Taxes, with an opinion of a qualified tax counsel chosen by TowerCo and reasonably acceptable to the Tax Indemnitee, to the effect that there is a reasonable basis that is consistent with the standards provided for in ABA Formal Opinion 85-352 as in effect (on the date hereof) for the position to be asserted in contesting the matter in question, (2) no event of default by TowerCo under this Sublease shall have occurred and be continuing, (3) such contest does not involve a material risk to the Tax Indemnitee of sale, forfeiture, or loss of, or the creation of any lien on, any of the Subleased Property or the imposition of criminal penalties, (4) TowerCo shall have acknowledged, in writing, that the contest is with respect to a liability that is indemnifiable by TowerCo pursuant to the terms of this Section 39(d), (5) if TowerCo reasonably requests, and the Tax Indemnitee elects to pursue, a contest that requires payment of the Tax as a condition to pursuing the contest, TowerCo shall loan, on an interest-free basis, sufficient funds to the Tax Indemnitee to pay the Tax and any interest or penalties due on the date of payment, and shall fully indemnify the Tax Indemnitee for any adverse Tax consequences resulting from such advance. The Tax Indemnitee shall not make, accept, or enter into a settlement or other compromise with respect to any Taxes indemnified pursuant to Section 39(a) or forego or terminate any such proceeding with respect to Taxes indemnified pursuant to this Section 39(b), without the prior written consent of TowerCo, which consent shall not be unreasonably withheld. If TowerCo requests in writing that the Tax Indemnitee accept a settlement of a claim offered by the IRS (other than an offer conditioned upon the Tax Indemnitee's agreement with respect to any issue wholly or partly unrelated to the transactions contemplated by the Transaction Documents), the Tax Indemnitee shall either accept such settlement offer or agree with TowerCo that TowerCo's liability pursuant to Section 39 hereof shall be limited to an amount calculated on the basis of such settlement offer. The Tax Indemnitee shall not be required to appeal any adverse decision of the United States Tax Court, a Federal District Court, or any comparable trial court. SECTION 40. General Provisions.
