SECTION 3. Tower Operator Lease of Lease Site and Occupancy Rights With Respect to Managed Sites.

(a) Lease Sites.

As to each Site, this Agreement is a grant of a leasehold, license or other interest in such Site (with respect to Sites that are owned by an AT&T Lessor in fee simple) or a subleasehold, sublicense or other interest in such Site (with respect to Sites that are subject to Ground Leases). The rights granted to Tower Operator under this Agreement include, with respect to each Tower, the right of Tower Operator to use and employ, to the extent such rights may be legally granted to or used by Tower Operator, the

-21-

Tower Related Assets related to the Sites. AT&T Lessors and Tower Operator acknowledge and agree that this single Agreement is indivisible, intended to cover all of the Sites and is not a separate lease and sublease or agreement with respect to individual Sites, and for bankruptcy-law purposes (and without impairing the express rights of any Party hereunder), all Parties intend that this Agreement be treated as a single indivisible agreement.

(b) Additional Lease Sites. Each Lease Site that is not an Initial Lease Site shall be made subject to this Agreement by means of a Subsequent Closing (after which the AT&T Lessors and Tower Operator shall execute and deliver at a Documentary Subsequent Closing an amendment of Exhibit B hereto to reflect such Site as a Lease Site instead of a Managed Site).

Notwithstanding anything to the contrary herein, no leasehold, subleasehold or other real property interest is granted pursuant to Section 3(a) in the Included Property of any Managed Site until the Subsequent Closing (if any) at which such Managed Site is converted to a Lease Site; provided, however, that for U.S. federal income Tax purposes this Agreement shall be treated as a lease of the Managed Sites as described in Section 3(i). The rights granted to Tower Operator under this Agreement include, with respect to each Tower, the right of Tower Operator to use and employ, to the extent such rights may be legally granted to or used by Tower Operator, the Tower Related Assets related to the Managed Sites. In performing its duties as operator of the Included Property of the Managed Sites, Tower Operator shall manage, administer and operate the Included Property of each of the Managed Sites, subject to the provisions of this Agreement, in a commercially reasonable manner and pursuant to standards at least equal to those Tower Operator uses to manage, administer and operate the Included Property of the Lease Sites. Except as expressly provided herein (including Section 28), no AT&T Ground Lease Party nor AT&T Lessor shall exercise any rights or take any actions with respect to the operation, maintenance, leasing or licensing of the Included Property of any Managed Sites, all such rights being exclusively reserved to Tower Operator hereunder.

(d) Tower Operator Acceptance of Sites. Tower Operator hereby accepts the Included Property of each Site in its “AS IS” condition, without any representation or warranty of or from any AT&T Lessor or AT&T Guarantor or any of their respective Affiliates whatsoever as to its condition or suitability for the Permitted Use or any other particular use, except as may be expressly set forth in the Master Agreement, the remedies for a breach of which shall be solely under and subject to the terms, conditions and limitations thereof. Except as set forth in the Master Agreement, Tower Operator hereby acknowledges that none of the AT&T Lessors or AT&T Guarantor or any of their respective agents or Affiliates has made any representation or warranty, express or implied, with respect to any of the Included Property, or any portion of such Included Property, or the suitability or fitness for the conduct of Tower Operator’s business or for any other purpose, including the Permitted Use.

(e) Site Related Revenue. During the Term, Tower Operator shall receive and shall be entitled to all of the revenue generated by the Included Property of such Site that results

-22-

from the Permitted Use of the Site (other than the Rent and Pre-Lease Rent payable hereunder, any Option Purchase Price and revenue generated by an AT&T Group Member pursuant to the provision of services described in Section 19(d) of the MPL Site MLA), including all revenue under the Collocation Agreements accruing from and after the Effective Date and all revenue received under the Collocation Agreements on or prior to the Effective Date for or with respect to periods from and after the Effective Date, and no AT&T Lessor or any of its Affiliates shall be entitled to any of such revenue. Except as may be expressly provided otherwise in the Transition Services Agreement, if any such revenue is paid to any AT&T Lessor or its Affiliates, such AT&T Lessor or its Affiliate receiving such revenue shall remit such revenue to Tower Operator promptly after receiving such revenue. Each AT&T Lessor and the applicable AT&T Ground Lease Party (as applicable) shall direct (or cause its Affiliate to direct), in writing, all payers of amounts due and accruing after the Effective Date under the Collocation Agreements to pay such amounts to Tower Operator.

(f) Site Related Expenses. From and after the Effective Date, except as otherwise expressly provided in this Agreement or any other Transaction Document, Tower Operator shall be responsible for the payment of, and shall pay, all expenses due and accruing from and after the Effective Date and related to or associated with the Included Property of the Sites, whether ordinary or extraordinary, and whether foreseen or unforeseen, including all expenses due and accruing from and after the Effective Date under the Ground Leases and the Collocation Agreements. Each AT&T Lessor and the applicable AT&T Ground Lease Party (as applicable) shall direct (or cause its Affiliate to direct) applicable third parties, in writing, that all such expenses due and accruing after the Effective Date be collected from Tower Operator.

(g) Revenue Sharing Payments. AT&T Lessors shall pay, as and when due, AT&T’s Share of Transaction Revenue Sharing Payments that are required to be made in respect of the Rent and Pre-Lease Rent for all Sites. Tower Operator shall pay, as and when due, Tower Operator’s Share of Transaction Revenue Sharing Payments that are required to be made in respect of the Rent and Pre-Lease Rent for all Sites.

(h) Filing of Financing Statements. Each AT&T Lessor hereby irrevocably authorizes Tower Operator or its designee to file in any relevant jurisdiction, at any time and from time to time, (x) any UCC-1 financing statement, which shall be substantially in the form of Exhibit F hereto, and any amendments thereto, (y) any memoranda of leases or Managed Sites, which shall be substantially in the form of Exhibit G hereto and any amendments thereto and (z) any memoranda of assignment, which shall be substantially in the form of Exhibit H hereto and any amendments thereto, that are in each case necessary or desirable to evidence, perfect or otherwise record Tower Operator’s leasehold or management interest in each Site, as applicable, granted pursuant to this Agreement and the other Transaction Documents. Each AT&T Lessor agrees, promptly upon request by Tower Operator, to use commercially reasonable efforts to provide Tower Operator with any information that is required or requested by Tower Operator in connection with the filing of any such financing statement or document.

(i) Tax Treatment. Notwithstanding anything to the contrary in this Agreement, and in accordance with the Tax Assumptions set forth in Section 34(a)(i), the Parties acknowledge and agree that this Agreement is intended to be treated for U.S. federal income Tax purposes as a lease between Tower Operator and the AT&T Lessors with respect to each of the

-23-

Lease Sites and the Managed Sites (excluding any Managed Sale Sites), and the Parties further agree to not take any position on any Tax return that is inconsistent with such treatment.

SECTION 4. Tower Operator Rights and Obligations Under the Ground Leases.

(a) Compliance with Ground Leases. Tower Operator hereby acknowledges that, as to the Included Property of each Site, this Agreement is subject and subordinate to all of the terms and conditions of the applicable Ground Lease of such Site. From and after the Effective Date, Tower Operator shall promptly pay or cause to be paid the Ground Rent under each Ground Lease for each Site during the Term of this Agreement when such payments become due and payable and, if Tower Operator fails to pay Ground Rent under any Ground Lease on a timely basis as required hereby, Tower Operator shall be responsible for any applicable late charges, fees or interest payable to the Ground Lessor arising after the Effective Date. Tower Operator shall abide by, comply with and perform all applicable terms, covenants, conditions and provisions of each Ground Lease (including terms, covenants, conditions and provisions relating to maintenance, insurance and alterations) as if Tower Operator were the “ground lessee” under the applicable Ground Lease and, to the extent evidence of such performance must be provided to a Ground Lessor, Tower Operator shall provide such evidence to such Ground Lessor (in each case unless such performance obligation is such that it requires performance by an AT&T Collocator of such obligations pursuant to the applicable Ground Lease or the MPL Site MLA). Should any Ground Lessor refuse the payment of Ground Rent for an applicable Site from any Person other than the applicable AT&T Lessor or its Affiliate, as applicable, then such AT&T Lessor or its Affiliate, as applicable, shall promptly pay such amount after Tower Operator pays or causes such amount to be paid to such AT&T Lessor or its Affiliate with instructions for such AT&T Lessor or its Affiliate, as applicable, to pay such amount to the applicable Ground Lessor. To the extent that any Ground Lease imposes or requires the performance by the “ground lessee” thereunder of any duty or obligation that is more stringent than or in conflict with any term, covenant, condition or provision of this Agreement, the applicable term, covenant, condition or provision of such Ground Lease shall control and shall constitute the duties and obligations of Tower Operator under this Agreement as to the subject matter of such term, covenant, condition or provision. Tower Operator shall be responsible for any breaches of, or defaults under, any Ground Lease that are caused by Tower Operator or its authorized agents and employees. Tower Operator shall not engage in, and shall use commercially reasonable efforts to prevent any Tower Subtenant from engaging in, 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 the applicable AT&T Lessor’s or AT&T Ground Lease Party’s right as ground lessee under such Ground Lease, or to exercise any other rights or remedies to which Ground Lessor may be entitled for a default or breach under the applicable Ground Lease. In no event shall Tower Operator have any liability to any AT&T Group Member for any breach of, or default under, a Ground Lease caused by an act of, or failure to perform a duty required to be performed by, AT&T Collocator, any AT&T Lessor, any AT&T Ground Lease Party or any AT&T Group Member or a breach of this Agreement or the MPL Site MLA by any AT&T Collocator or any AT&T Lessor.

-24-

(b) Tower Operator Rights Under Ground Leases; Power of Attorney. Each AT&T Lessor hereby delegates to Tower Operator the sole and exclusive right to perform the obligations of, and assert and exercise the rights of, such AT&T Lessor and all AT&T Ground Lease Parties under all Ground Leases, subject to the terms and conditions of this Agreement and the MPL Site MLA. Tower Operator shall be entitled, subject to the standards set forth in Section 2(d) and this Section 4(b), to review, negotiate and execute any Tower Operator Negotiated Renewal, waiver, amendment, extension, renewal, sequential lease, adjacent lease, non-disturbance agreement and other documentation relating to Ground Leases that (i) Tower Operator determines in good faith is on commercially reasonable terms, (ii) is of a nature and on terms to which Tower Operator would agree (in light of the circumstances and conditions that exist at such time) in the normal course of business if it were the direct lessee under the related Ground Lease rather than a sublessee thereof pursuant to this Agreement and (iii) otherwise satisfies the following requirements of this Section 4 (each, an “Authorized Ground Lease Document”). Each AT&T Lessor hereby grants Tower Operator a limited power of attorney and hereby appoints Tower Operator as its attorney in fact to (x) review, negotiate and execute on behalf of such AT&T Lessor all Authorized Ground Lease Documents, all Authorized Collocation Agreement Documents related to the Managed Sites and all other documents contemplated and permitted by this Agreement or necessary to give effect to the intent of this Agreement and the transactions contemplated by this Agreement and the other Transaction Documents, but excluding any Unauthorized Documents and (y) prepare and submit any applications or requests for Governmental Approvals, including with respect to Zoning Laws, related to operating the Site or to support the needs of a Tower Subtenant. Each AT&T Lessor agrees to execute, from time to time, such other documents and certificates (including a separate power of attorney, including a power of attorney in the form attached as Exhibit K) as Tower Operator may reasonably request to evidence the power of attorney granted in the preceding sentence and the appointment of Tower Operator as such AT&T Lessor’s attorney thereby. AT&T Guarantor agrees to cause each AT&T Ground Lease Party to grant and execute a limited power of attorney and to appoint Tower Operator as its attorney in fact, to review, negotiate and execute on behalf of such AT&T Ground Lease Party all Authorized Ground Lease Documents, all Authorized Collocation Agreement Documents related to the Managed Sites and all other documents contemplated and permitted by this Agreement or necessary to give effect to the intent of this Agreement and the transactions contemplated by this Agreement and the other Transaction Documents, but excluding any Unauthorized Documents. Each AT&T Lessor agrees, and AT&T Guarantor agrees to cause each AT&T Ground Lease Party, to execute and deliver, as promptly as reasonably practicable and in any event within 15 Business Days following request therefor by Tower Operator, any Authorized Ground Lease Document, any Authorized Collocation Agreement Document and any other document contemplated and permitted by this Agreement or necessary to give effect to the intent of this Agreement and the other Transaction Documents. Except as expressly provided above in this Section 4(b) or otherwise in this Agreement, Tower Operator shall not be entitled to act as agent for, or otherwise on behalf of, any AT&T Lessor or its Affiliate or to bind any AT&T Lessor or its Affiliate in any way whatsoever.

(c) Exercise of Existing Ground Lease Extensions. During the term (including any renewal terms) of any Ground Lease relating to any Site, Tower Operator agrees to timely exercise prior to the expiration of the applicable Ground Lease and in accordance with the provisions of the applicable Ground Lease, any and all extension options existing as of the

-25-

Effective Date, in accordance with Section 4(d). Each AT&T Lessor and AT&T Ground Lease Party agrees that it will not take any action with respect to any Ground Lease that is reasonably likely to cause such Ground Lease to be prematurely terminated without the prior written approval of Tower Operator, in Tower Operator’s reasonable and good faith determination. Notwithstanding the foregoing, Tower Operator shall not be required to exercise any Ground Lease extension option (A) if AT&T Collocator at the Site covered by such Ground Lease is in default of its obligations under the MPL Site MLA as to the Site beyond applicable notice and cure periods provided therein, (B) if the then remaining term of such Ground Lease (determined without regard to such extension option) shall extend beyond the term of the MPL Site MLA as to such Site taking into account all renewal options that may be exercised by AT&T Collocator under the MPL Site MLA or (C) if as to such Site, AT&T Collocator has given a Termination Notice under the MPL Site MLA whose effective date precedes the expiration date of the Ground Lease (determined without regard to such extension option).

(d) Negotiation of Additional Ground Lease Extensions.

(i) Tower Operator shall use commercially reasonable efforts, consistent with its normal course of business for ground leased tower sites where Tower Operator or its Affiliate are the direct lessees under the ground lease, to negotiate and obtain, in accordance with the standards set forth in Section 2(d), the further extension of the term of all Ground Leases subject to the provisions of Section 4(b) and this Section 4(d). Each AT&T Lessor, if requested by Tower Operator, shall use commercially reasonable efforts to assist Tower Operator in obtaining such further extensions (and not interfere with Tower Operator); provided, however, that such AT&T Lessor shall not be required to expend any funds in connection therewith or accept any liability for which Tower Operator is responsible under this Agreement. Beginning on the date that is seven (7) years prior to such expiration, Tower Operator will reasonably apprise the applicable AT&T Lessor or AT&T Ground Lease Party, on the applicable AT&T Lessor’s or AT&T Ground Lease Party’s request from time to time (but no more frequently than two (2) times per year), of the progress of Tower Operator’s negotiations with the applicable Ground Lessor. Tower Operator shall be fully responsible for any Tower Operator Negotiated Increased Revenue Sharing Payments. Tower Operator shall have the exclusive right to negotiate with Ground Lessors and obtain the further extension of the term of all Ground Leases at all times until the date that is two (2) years before the expiration date of the applicable Ground Lease (or until the date that is six (6) months prior to the expiration date of the applicable Ground Lease in the case of a Ground Lease the Ground Lessor in respect of which is a Governmental Authority). If the applicable Ground Lease contains a right of first offer, right of first refusal or similar provision in favor of the lessee thereunder, Tower Operator shall have the exclusive right to exercise the rights under such provision; provided, however, that if Tower Operator fails to exercise its rights under such provision, the applicable AT&T Lessor or its Affiliate shall be entitled to exercise the lessee’s rights thereunder and Tower Operator shall do all things reasonably necessary to facilitate such exercise. In furtherance of the foregoing, the applicable AT&T Lessor shall do all things reasonably necessary to facilitate the exercise of any right of first offer, right of first refusal or similar provision by Tower Operator, and Tower Operator shall use commercially reasonable efforts to coordinate its exercise or non-exercise of any right of first offer, right of first refusal or similar

-26-

provision with the applicable AT&T Lessor or its Affiliate so as to permit such AT&T Lessor or Affiliate to timely exercise any such right in the event Tower Operator declines to do so.

(ii) Tower Operator shall provide AT&T Lessors with (A) a quarterly summary of all Tower Operator Negotiated Renewals entered into for such given quarter, (B) promptly upon execution thereof, a copy of any Tower Operator Negotiated Renewal or any other document executed by Tower Operator as attorney for any AT&T Lessor or any AT&T Ground Lease Party pursuant to a power of attorney granted pursuant to or as contemplated by Section 4(b), which may be provided in electronic form and (C) all related material documents executed in connection with any Tower Operator Negotiated Renewal as may be reasonably requested by any AT&T Lessor (except privileged or confidential documents or where such disclosure is prohibited by Law).

(iii) Tower Operator shall provide the applicable AT&T Lessor or AT&T Ground Lease Party with notice (a “Tower Operator Extension or Relocation Notice”) no later than two (2) years before the expiration of any Ground Lease which does not include provisions of renewal beyond the scheduled expiration date (other than with respect to any such Ground Lease that is scheduled to expire within two (2) years following the Effective Date). The Tower Operator Extension or Relocation Notice shall set forth (A) Tower Operator’s intent to negotiate an extension or renewal of such Ground Lease (in which case Tower Operator shall provide subsequent notification of the progress of such negotiations, including the successful completion of the negotiations) or (B) Tower Operator’s intent to pursue an alternative site that is in all material respects suitable for AT&T Collocator’s use at no additional cost to AT&T Collocator (in which case such notice shall also describe Tower Operator’s plans to relocate AT&T Communications Equipment in a manner that shall result in no costs to AT&T Collocator and no interruption of AT&T Collocator’s business).

(iv) If Tower Operator fails to timely deliver a Tower Operator Extension or Relocation Notice or AT&T Collocator, in its reasonable discretion, determines that Tower Operator’s plans for an alternative site are not acceptable, the applicable AT&T Lessor or its Affiliate shall have the right, but not the obligation, to commence negotiations with the applicable Ground Lessor under the expiring Ground Lease; provided, however, that such AT&T Lessor (and its Affiliates) may not commence such negotiations until the date that is two (2) years before the expiration date of the applicable Ground Lease (or until the date that is six (6) months prior to the expiration date of the applicable Ground Lease in the case of a Ground Lease the Ground Lessor in respect of which is a Governmental Authority) and shall act in good faith to not purposely adversely affect Tower Operator’s economic interests in the applicable Site at any time; provided, further, that such AT&T Lessor or its Affiliate must negotiate any extension on commercially reasonable terms. Upon notice from the applicable AT&T Lessor that it intends to commence such negotiations, Tower Operator shall cease all efforts to negotiate an extension or renewal of the applicable Ground Lease and such AT&T Lessor or its Affiliate may negotiate an extension or renewal of the applicable Ground Lease on commercially reasonable terms. If the applicable AT&T Lessor or its Affiliate completes the foregoing negotiations for, and executes, such Ground Lease

-27-

extension or renewal, then such AT&T Lessor shall provide notice to Tower Operator of same (the “AT&T Lessor Extension Notice”) and this Agreement shall terminate as to the applicable Site as of the day immediately preceding the commencement of such Ground Lease extension or renewal and shall have no further force and effect except for the obligations accruing prior to or as of the termination date for such Site, unless the applicable AT&T Lessor or its Affiliate elects to compel Tower Operator to, or Tower Operator notifies such AT&T Lessor or its Affiliate within 30 days of its receipt of the AT&T Lessor Extension Notice that it elects to, resume Tower Operator’s obligations under Section 4(a) and the MPL Site MLA to comply with all terms, covenants, conditions and provisions of such Ground Lease as if Tower Operator were the “ground lessee” under such Ground Lease by notifying such AT&T Lessor of same; provided that the applicable AT&T Lessor or AT&T Ground Lease Party may compel Tower Operator to resume its obligations only if the terms of such Ground Lease comply with the standards set forth on Schedule 5(d). If the applicable AT&T Lessor or AT&T Ground Lease Party elects to compel or if Tower Operator elects to resume its obligations under Section 4(a) and the MPL Site MLA, then (x) Tower Operator shall reimburse the applicable AT&T Lessor or its Affiliate for all reasonable costs incurred in connection with the extension or renewal of such Ground Lease and shall be responsible for all incremental costs relating to such Ground Lease going forward, (y) Tower Operator shall accept and comply with the terms of such Ground Lease as negotiated by such AT&T Lessor or its Affiliate and (z) this Agreement shall continue in full force and effect with respect to such Site as if such extension or renewal was a Tower Operator Negotiated Renewal.

(v) The failure of Tower Operator to provide a Tower Operator Extension or Relocation Notice shall not constitute an event of default or allow any AT&T Lessor or any AT&T Ground Lease Party to exercise remedies under this Agreement if the expiring Ground Lease is nevertheless extended or renewed, or a new Ground Lease or similar arrangement is entered into, prior to the Ground Lease’s expiration.

(vi) If Tower Operator does not extend or otherwise secure the tenure of a Ground Lease in accordance with this Section 4(d), then this Agreement shall expire as to the Site to which such Ground Lease applies (but not with respect to any other Site) as of the day before the expiration date of the applicable Ground Lease and this Agreement shall have no further force and effect as to such Site except for the obligations accruing prior to or as of the expiration date that are then unperformed (including, without limitation, in Section 9).

(e) Acquisition of Ground Lease by Tower Operator Affiliate or AT&T Affiliate. In the event that Tower Operator or its Affiliate acquires an interest in fee simple or an easement in the Land of any Site that is subject to a Ground Lease as of the Effective Date, Tower Operator or such Affiliate shall execute and deliver such documentation as is necessary to create a ground lease with respect to such Site with the applicable AT&T Lessor for such Site (which ground lease shall be subject to the terms of this Agreement as the Ground Lease hereunder) for a term of no less than fifty (50) years from the date of such acquisition (or, if earlier, the length of the applicable easement) and on other terms (including rent payment terms)

-28-

substantially the same as the terms of the applicable Ground Lease in effect as of the Effective Date. In the event that any AT&T Lessor or any of their Affiliates acquires an interest in fee simple or an easement in the Land of any Site that is subject to a Ground Lease as of the Effective Date, the applicable AT&T Lessor or such Affiliate shall execute and deliver such documentation as is necessary to create a ground lease with respect to such Site with the applicable AT&T Lessor for such Site (which ground lease shall be subject to the terms of this Agreement as the Ground Lease hereunder) for a term of no less than fifty (50) years from the date of such acquisition (or, if earlier, the length of the applicable easement) and on other terms (including rent payment terms) substantially the same as the terms of the applicable Ground Lease in effect as of the Effective Date.

SECTION 5. AT&T Lessor Rights and Obligations With Respect to the Ground Leases.

(a) As to any Site, no AT&T Lessor or any other AT&T Group Member shall be deemed to have assumed any duty or obligation of the Ground Lessor under the applicable Ground Lease and no AT&T Lessor or any other AT&T Group Member shall be liable or responsible in any manner whatsoever for any failure of such Ground Lessor to perform any such duty or obligation.

(b) Upon receipt by any AT&T Lessor or any other AT&T Group Member of any notice of default or notice of an act or omission that could with the passing of time or the giving of notice constitute an event of default under a Ground Lease or non-compliance with a term of a Ground Lease (a “Default Notice”), such AT&T Lessor shall, within 10 Business Days after receipt of such Default Notice, provide Tower Operator with a copy of the Default Notice. If such default or non-compliance with a term of a Ground Lease is caused by any Person other than any AT&T Lessor, AT&T Collocator or any other AT&T Group Member or any of their agents or employees, Tower Operator shall promptly cure or otherwise remedy such default or noncompliance at its sole cost and expense. If such default or non-compliance is caused by any AT&T Lessor, AT&T Collocator or any other AT&T Group Member or any of their agents or employees, AT&T Lessors or AT&T Collocator shall cause such default or non-compliance to be cured or otherwise remedied at its sole cost and expense.

(c) If Tower Operator does not pay all or any portion of the Ground Rent when due and payable, or if Tower Operator breaches or commits a default under any other term of a Ground Lease, and either (x) Tower Operator is not diligently and in good faith contesting the same or (y) a Risk of Forfeiture exists as a result of the same, then the applicable AT&T Lessor or AT&T Ground Lease Party may seek to cure such default under any applicable Ground Lease by making payment of the unpaid Ground Rent or performance of the breached or defaulted obligation to the applicable Ground Lessors. Within 10 days following receipt of an invoice therefor, Tower Operator shall reimburse the applicable AT&T Lessor or AT&T Ground Lease Party for all such payment or performance by such AT&T Lessor or AT&T Ground Lease Party under the Ground Lease.

-29-

SECTION 6. Collocation Agreements with Third Parties.

(a) Collocation Agreements Generally. Tower Operator acknowledges that, as to each Site, this Agreement is subject to all Collocation Agreements currently in effect with respect to such Site.

(b) Collocation Agreements for Lease Sites. In respect of each Lease Site, by execution of this Agreement as to the Initial Lease Sites and thereafter as of the Subsequent Closing Date for each additional Lease Site, the applicable AT&T Lessor does transfer, assign and convey over unto Tower Operator, for the Term as to such Lease Site, all of its rights, title and interest in, to or under any Collocation Agreements affecting or relating to such Lease Site, and shall execute all documentation prepared by Tower Operator or a Tower Subtenant and reasonably necessary to confirm same to a counterparty under a Collocation Agreement, at Tower Operator’s sole cost and expense within 15 Business Days of receipt of a request therefor from Tower Operator; provided, however, that, if AT&T Lessor or an AT&T Ground Lease Party reasonably determines it to be unduly burdensome, such AT&T Lessor or AT&T Ground Lease Party shall not be required to obtain any new board resolutions from any Person that is a corporation or similar resolutions or approvals from any Person that is a limited liability company, partnership, trust or other legal entity. In accordance with the provisions of Section 2(d), Tower Operator may enter into waivers, amendments, extensions, renewals and any other documentation relating to any Collocation Agreements, to the extent they apply to the Lease Sites, or enter into new Collocation Agreements applicable to the Lease Sites (collectively, the “Authorized Collocation Agreements Documents”). Each AT&T Lessor hereby assigns and delegates to Tower Operator the sole and exclusive right to perform the obligations of and assert and exercise the rights of such AT&T Lessor under and enforce the terms of all Collocation Agreements with respect to Lease Sites subject to the provisions of Section 2(d).

(c) Collocation Agreements for Managed Sites. In respect of each Managed Site, the applicable AT&T Lessor and each AT&T Ground Lease Party does hereby (on its behalf and on behalf of any Affiliate thereof that is a party thereto) delegate all of its respective rights, duties, obligations and responsibilities under the Collocation Agreements to Tower Operator for the Term as to such Site for periods occurring from and after the Effective Date, and shall execute all documentation reasonably requested and prepared by Tower Operator to confirm same to a counterparty under a Collocation Agreement, at Tower Operator’s sole cost and expense within 15 Business Days of receipt of a request therefor from Tower Operator; provided, however, that, if AT&T Lessor or an AT&T Ground Lease Party reasonably determines it to be unduly burdensome, such AT&T Lessor and each AT&T Ground Lease Party shall not be required to obtain any new board resolutions from any Person that is a corporation or similar resolutions or approvals from any Person that is a limited liability company, partnership, trust or other legal entity. In accordance with the provisions of Section 2(d), Tower Operator may enter into waivers, amendments, extensions, restatements, renewals and any other documentation relating to any Collocation Agreements, to the extent they apply to the Managed Sites, or enter into new Collocation Agreements applicable to the Managed Sites. Each AT&T Lessor hereby (i) assigns and delegates to Tower Operator the sole and exclusive right to perform the obligations of and assert and exercise the rights of such AT&T Lessor and all AT&T Ground Lease Parties under all Collocation Agreements during the Term with respect to Managed Sites, subject to the provisions of Section 2(d), and (ii) hereby grants Tower Operator a

-30-

limited power of attorney and hereby appoints Tower Operator as its attorney in fact to assert and exercise the rights of such AT&T Lessor and all AT&T Ground Lease Parties under all Collocation Agreements during the Term.

(d) Tower Operator Assumption of Obligations and Benefits Under Collocation Agreements. Tower Operator does hereby assume and agree to pay and perform all of the duties, obligations, liabilities and responsibilities of the AT&T Lessors and all AT&T Ground Lease Parties under the Collocation Agreements affecting each Site arising from and after the Effective Date, except as otherwise expressly provided in this Agreement, and Tower Operator shall receive all revenue, rents, issues or profits payable under the Collocation Agreements accruing from and after the Effective Date and all revenue, rents, issues or profits received with respect to such agreements on or prior to the Effective Date for or with respect to periods from and after the Effective Date.

(e) End of Term. Unless Tower Operator exercises the Purchase Option with respect to a Site under Section 20, the assignment by the applicable AT&T Lessor to Tower Operator of the Collocation Agreements in respect of each Site shall automatically terminate and expire and all Collocation Agreements (including, for clarity, Collocation Agreements entered into by Tower Operator after the Effective Date) shall automatically be (or be deemed) reassigned or assigned, as the case may be, to such AT&T Lessor or its designee, and such AT&T Lessor or its designee shall accept such reassignment or assignment, as the case may be, upon the expiration of the Term of, or earlier termination of, this Agreement in respect of such Site; provided, however, that the applicable AT&T Lessor or AT&T Ground Lease Party may refuse to accept such reassignment or assignment of a Collocation Agreement if any Lien (other than any Lien (i) existing on the date of this Agreement and created by a Person other than Tower Operator, (ii) created by the AT&T Lessors or any of their Affiliates or (iii) that does not diminish the value of such Collocation Agreement or the related Site) exists against such Collocation Agreement at the time of such reassignment or assignment and is not released or discharged upon the consummation of such reassignment or assignment. Tower Operator shall execute all documentation reasonably necessary to confirm such reassignment or assignment, as the case may be, to a counterparty under a Collocation Agreement, at AT&T Lessor’s sole cost and expense; provided, however, that, if Tower Operator reasonably determines it to be unduly burdensome, Tower Operator shall not be required to obtain any new board resolutions from any Person that is a corporation or similar resolutions or approvals from any Person that is a limited liability company, partnership, trust or other legal entity.

(f) New Collocation Agreements. Subject to Section 2(d), Tower Operator shall be permitted to negotiate and enter into, amend or modify any Collocation Agreements in its sole discretion, without the consent of any AT&T Lessor; provided, however, that such Collocation Agreements must comply with the requirements set forth in Section 2(d)(C).

SECTION 7. Tower Operator Permitted Use.

(a) Tower Operator shall use, and shall permit the use of, the Included Property of each Site only for the Permitted Use.

-31-

(b) Each AT&T Lessor shall reasonably cooperate with Tower Operator, at Tower Operator’s sole cost and expense, in executing documentation related to any easement or right of way necessary for Site-related utilities or otherwise required in connection with the operation by Tower Operator of any Site for the Permitted Use; provided, however, that such easement or right of way shall not materially and adversely affect AT&T Collocator’s operation, use or enjoyment of the AT&T Collocation Space on the applicable Site.

SECTION 8. Tower Operator Access. Except to the extent limited by any restrictions contained in any applicable Ground Lease, the Permitted Liens, the MPL Site MLA, this Agreement or by Law, the interest or rights of Tower Operator in or to each Site under this Agreement includes, as an appurtenance thereto, a non-exclusive right for access to the Included Property of each Site on a 24-hour, seven day per week basis, on foot or motor vehicle, including trucks and other heavy equipment. The Parties acknowledge and agree that the right to access any portion of the Included Property of each Site granted pursuant to this Section 8 shall be granted to Tower Operator and its authorized contractors, subcontractors, engineers, agents, advisors, consultants, representatives, or other persons authorized by Tower Operator, and to Tower Subtenants, subject to any restrictions contained in the applicable Ground Lease, the Permitted Liens, the MPL Site MLA, this Agreement or by Law.

SECTION 9. Term and End of Term Obligations.

(a) Term. The term of this Agreement, as to each Lease Site, shall commence on the Effective Date with respect to the Initial Lease Sites and on the Subsequent Closing Date with respect to all other Lease Sites, and in each case shall expire on the applicable Site Expiration Date, subject to the termination provisions of Section 29, Section 35 and Section 36 and the other provisions of this Agreement. The term of this Agreement, as to each Managed Site, shall commence on the Effective Date and shall expire on the applicable Site Expiration Date, subject to the termination provisions of Section 29, Section 35 and Section 36 and the other provisions of this Agreement; provided, however, that as of a Subsequent Closing Date under the terms of the Master Agreement, such Managed Site shall become a Lease Site hereunder, and no further instrument shall be required to evidence such conversion; provided further, however, that upon the request of any Party, the Parties shall promptly execute such instruments as may be reasonably required to further evidence such conversion. This Agreement shall remain in full force and effect until the expiration or earlier termination of the term of this Agreement as to all Sites.

(b) Assignment, Restoration and Removal.

(i) Upon the expiration or earlier termination of the Term as to any Site due to expiration or termination of any Ground Lease, the applicable AT&T Lessor or AT&T Ground Lease Party shall transfer such Site to Tower Operator in accordance with and as described in Section 20(c), subject to the applicable AT&T Lessor’s or AT&T Ground Lease Party’s receipt of any consent required for such assignment (which such AT&T Lessor or AT&T Ground Lease Party shall use commercially reasonable efforts to obtain), whereupon the applicable AT&T Lessor or AT&T Ground Lease Party shall be released from any and all further obligations under such Ground Lease and under this Agreement in respect of such Site (including, without limitation, Section 20), and

-32-

Tower Operator hereby acknowledges and consents to such release. Notwithstanding the foregoing or any provision herein to the contrary, the applicable AT&T Lessor or AT&T Ground Lease Party shall remove any ground-based electronics, batteries, fuel tanks and Hazardous Materials from each Site that were introduced or employed by AT&T Collocator or another AT&T Group Member or under any of their supervision or direction by or before the expiration or earlier termination of the Term as to any Site due to expiration or termination of any Ground Lease.

(ii) If the applicable AT&T Lessor or AT&T Ground Lease Party cannot assign its ownership interest in a Site to Tower Operator in accordance with Section 9(b)(i), then upon the expiration or earlier termination of the Term as to any Site, and if required by the applicable Ground Lease or otherwise reasonably necessary to prevent liability of the applicable AT&T Lessor or AT&T Ground Lease Party to the Ground Lessor or any Governmental Authority, Tower Operator, if requested by the applicable AT&T Lessor or AT&T Ground Lease Party, shall, in accordance with instructions of such AT&T Lessor or AT&T Ground Lease Party, within a reasonable period of time, but in no event less than the period of time as may be required under any applicable Ground Lease, (A) cause the Tower Subtenants on such Site to stop and cease the operation of their respective Communications Equipment on such Site (unless prohibited by a Tower Subtenant’s Collocation Agreement entered into before the Effective Date and not amended or modified by or its term extended by Tower Operator after the Effective Date) and (B) remove the Tower and any Improvements (whether or not constituting Severable Modifications) other than AT&T Improvements from such Site and otherwise restore such Site to the condition required under the applicable Ground Lease or applicable Law.

(iii) The Tower and any Improvements so removed (to the extent not constituting Severable Modifications of Tower Operator) shall either be (A) delivered by Tower Operator to any Person designated by the applicable AT&T Lessor or AT&T Ground Lease Party for disposition by such AT&T Lessor or AT&T Ground Lease Party or its designee, who shall reimburse Tower Operator for its cost of removal thereof, in an amount not to exceed the net sales proceeds such Person receives from the dispositions thereof, if any, or (B) sold or otherwise disposed of by Tower Operator, and the net proceeds of such sale or other disposition after deducting Tower Operator’s cost of removal thereof shall be paid to the applicable AT&T Lessor or AT&T Ground Lease Party when and as received by Tower Operator.

(iv) Any Severable Modifications not removed by Tower Operator within such 30-day period shall, at the applicable AT&T Lessor’s or AT&T Ground Lease Party’s option, be deemed abandoned by Tower Operator and title to such Severable Modifications shall automatically, without further action, vest in such AT&T Lessor or AT&T Ground Lease Party; provided, however, that Tower Operator shall remain liable for the costs of removal of such Severable Modifications.

(c) No Refund or Credit for Rent or Pre-Lease Rent. Except as otherwise expressly provided in the Master Agreement, in the event of the expiration or termination of the Term as to any Site prior to its applicable Site Expiration Outside Date, and without limiting any

-33-

of Tower Operator’s other rights or remedies hereunder or under the Master Agreement or any Collateral Agreement, Tower Operator shall have no right or claim to any refund or credit of any portion of the prepaid Rent or Pre-Lease Rent for any Site.

(d) Additional End of Term Obligations. Upon the expiration or termination of the Term as to any Site (other than as a result of the conversion of such Managed Site to a Lease Site hereunder), if Tower Operator has not exercised its Purchase Option with respect to such Site, Tower Operator shall (i) if requested by the applicable AT&T Lessor or AT&T Ground Lease Party, deliver or cause to be delivered to such AT&T Lessor or AT&T Ground Lease Party, at such AT&T Lessor’s or AT&T Ground Lease Party’s sole cost and expense, (A) copies of all written (and effective) Ground Leases, Collocation Agreements and material Governmental Approvals solely related to such Site or, to the extent not solely related, appropriate extracts thereof, that are in effect and in its possession and (B) copies of, or extracts from, all current files and records of Tower Operator solely related to the ownership, occupancy or leasing of such Site or, to the extent not so solely related, appropriate extracts thereof (including a current rent roll and a list of current expenditures and the payees thereof); provided, however, that to the extent such documents are customarily maintained in electronic form accessible through commonly used business software, Tower Operator may deliver such documents in electronic form, except privileged or confidential documents or where such disclosure is prohibited by Law, (ii) assign to such AT&T Lessor or AT&T Ground Lease Party, at such AT&T Lessor’s or AT&T Ground Lease Party’s sole cost and expense, all Collocation Agreements, (iii) deliver notices of the expiration of the Term to any Ground Lessor and any counterparty to a Collocation Agreement, as applicable and as directed by such AT&T Lessor or AT&T Ground Lease Party, (iv) execute, at such AT&T Lessor’s or AT&T Ground Lease Party’s sole cost and expense, any recordable documentation required by such AT&T Lessor or AT&T Ground Lease Party in order to terminate any Memorandum of Site Lease Agreement with respect to such Sites, (v) use commercially reasonable efforts to provide to such AT&T Lessor or AT&T Ground Lease Party transition services of the type such AT&T Lessor or AT&T Ground Lease Party or their Affiliates are providing to Tower Operator in the Transition Services Agreement on commercially reasonable and then prevailing market terms, (vi) reasonably cooperate in good faith with such AT&T Lessor or AT&T Ground Lease Party to effect the efficient and orderly transition of possession, operation, regulatory compliance records, use or occupancy (as applicable) of such Sites and the related collocation business and (vii) enter into such agreements as are reasonably necessary to appropriately bifurcate the rights, interests, duties and obligations of Tower Operator under the Collocation Agreements.

SECTION 10. Tower Operator Rent and Pre-Lease Rent; Treatment for US Federal Income Tax Purposes.

(a) Rent Payments. Tower Operator, or an Affiliate of Tower Operator on its behalf, shall pay the AT&T Lessors (i) the Rent in respect of the Included Property of each Initial Lease Site for the entire Term as to such Lease Site in a single upfront payment on the Effective Date, which payment is set forth on Exhibit C hereto and (ii) the Pre-Lease Rent in respect of the Included Property of each Managed Site for the entire Term as to such Managed Site in a single upfront payment on the Effective Date, which payment is set forth on Exhibit C hereto. Tower Operator agrees that the Rent and the Pre-Lease Rent are non-refundable and that Tower Operator shall have no right of abatement, reduction, setoff, counterclaim, rescission,

-34-

recoupment, refund, defense or deduction with respect thereto, including in connection with any event of default by any AT&T Lessor, AT&T Collocator or their respective Affiliates or any casualty or condemnation except as otherwise expressly provided in this Agreement or the Master Agreement.

(b) Fixed Rent for Tax Purposes. Pre-Lease Rent and Rent are intended to constitute “fixed rent” (as such term is defined in Treasury Regulation § 1.467-1(h)(3)).

(c) Tax Allocation of Rent. The Rent and Pre-Lease Rent shall be specifically allocated to each period for use of the Lease Sites and Managed Sites, as the case may be, as set forth in Exhibit D (“Allocated Rent”); provided, however, that if any Managed Site becomes a Lease Site as a result of a Subsequent Closing, then the remaining portion of the Pre-Lease Rent allocable to the periods from and after the Subsequent Closing Date shall thereafter be allocated to and constitute Rent for the applicable Site for the corresponding periods after such Subsequent Closing Date; provided, further, that such re-allocation of Pre-Lease Rent shall not be done in a manner that causes this Agreement to be a disqualified leaseback or disqualified long term agreement under Treasury Regulation § 1.467-3. Notwithstanding that Rent and Pre-Lease Rent shall be payable in accordance with Section 10(a), and without limiting the Tower Operator’s obligations under Section 10(a), for federal income Tax purposes only, the Allocated Rent allocated pursuant to this Section 10(c) shall represent and be the amount of Rent or Pre-Lease Rent, as applicable, for which Tower Operator becomes liable on account of the use of each applicable Site for each calendar year, in whole or in part, of the Term.

(d) Code Section 467 Provisions. It is the intention of the Parties that the allocation of Rent or Pre-Lease Rent to each Rent Payment Period as provided in Exhibit D constitutes a specific allocation of fixed rent within the meaning of Treasury Regulation § 1.467-1(c)(2)(ii)(A), with the effect that pursuant to Treasury Regulations §§ 1.467-1(d) and 1.467-2, the AT&T Lessors and Tower Operator, on any federal income Tax returns filed by each of them (or on any federal income Tax returns (and any state and local income Tax returns that follow the reporting on the relevant party’s federal income Tax return) on which their income is included), will accrue the amounts of rental income and rental expense, respectively, set forth for each Rent Payment Period in Exhibit D under the caption “Proportional Rent” (the “Proportional Rent”) and will include such amounts in income for each taxable year in accordance with Treasury Regulation § 1.467-1(d)(1). Because there will be a difference from time to time between (i) the cumulative amount of Rent (or Pre-Lease Rent paid by Tower Operator (as set forth in Section 10(a)) and (ii) the cumulative amount of Rent and Pre-Lease Rent allocated pursuant to Section 10(c) solely for purposes of determining the AT&T Lessors’ and Tower Operator’s Tax consequences under Section 467 of the Code and for no other purpose, there shall be considered to exist a loan from Tower Operator to the applicable AT&T Lessor for purposes of Section 467 of the Code with respect to each Site, the amount of which is based on the difference between the cumulative amount of the Rent and Pre-Lease Rent paid by Tower Operator and the cumulative amount of the Proportional Rent accrued by Tower Operator adjusted to account for an interest component, as provided in Treasury Regulation § 1.467-4(b)(1), which amount is set forth in Exhibit D under the caption “Section 467 Loan” (the “Section 467 Loan”). Such positive amount represents a loan to the applicable AT&T Lessor and such AT&T Lessor shall deduct interest expense and Tower Operator shall accrue interest income, in each case, in an amount equal to that set forth in Exhibit D under the caption “Section 467 Interest” for the applicable

-35-

Rent Payment Period. All Section 467 Interest and principal in respect thereof, Proportional Rent and Allocated Rent are already included as part of Rent, are payable as a portion thereof, and have been taken into account in the calculation of the percentages set forth under the heading “Rent Percentage” on Exhibit D. In no event shall any principal or interest on any Section 467 Loan, or any Proportional Rent or Allocated Rent be separately payable as such (including upon any termination of this Agreement with respect to a Site), it being agreed and understood that these items represent characterizations for federal income Tax purposes only, including in any case of termination of this Agreement.

(e) Termination, Tax Allocations and Section 467 Loans. In connection with any termination of this Agreement with respect to any Site for any reason, Allocated Rent for such Site shall cease to accrue and the Section 467 Loan balance (including all accrued interest thereon) for such Site shall be deemed to be repaid for all purposes.

(f) Net Lease. This Agreement, insofar as it relates to the lease or the use and operation by Tower Operator of any Site or the Included Property on any Site, is a net lease by Tower Operator.

SECTION 11. Condition of the Sites and Obligations of Tower Operator.

(a) Repair and Maintenance Obligations of Tower Operator. Tower Operator has the obligation, right and responsibility to repair and maintain each Site in accordance with tower industry standards, including an obligation to maintain the structural integrity of all of the Towers and to ensure that all of the Towers have at all times the structural loading capacity to hold and support all Communications Equipment then mounted on the Tower. Tower Operator shall maintain and conduct, annually and on a rolling basis, a regularly scheduled tower inspection program that meets or exceeds tower industry standards, and Tower Operator shall provide AT&T Collocator, upon AT&T Collocator’s request from time to time, but not to be more frequently than on a quarterly basis, with a summary of the results of such inspection (which summary may be provided in electronic form). Subject to the other provisions contained in this Agreement, Tower Operator, at its sole cost and expense, shall monitor (including tower marking/lighting systems and alarms, if required), maintain, reinforce and repair each Site such that AT&T Collocator and Tower Subtenants may utilize such Site to the extent permitted in this Agreement.

(b) Compliance with Laws. Tower Operator’s installation, maintenance and repair of each Site shall comply in all material respects with all Laws and shall be performed in a manner consistent with or superior to the general standard of care in the tower industry. Tower Operator assumes all responsibilities, as to each Site, for any fines, levies or other penalties that are imposed as a result of non-compliance, commencing from and after the Effective Date with requirements of the applicable Governmental Authorities; provided, that AT&T Lessor shall be responsible for the portions of all such fines, levies or other penalties that are imposed for, or relating to, periods prior to the Effective Date and relate to non-compliance that existed prior to or on the Effective Date. AT&T Lessor assumes all responsibilities, as to each Site, for any fines, levies or other penalties imposed as a result of AT&T Lessor’s non-compliance from and after the Effective Date with such requirements of the applicable Governmental Authorities unless due to Tower Operator’s failure to perform its obligations under this Agreement or the MPL Site

-36-

MLA. Without limiting the foregoing, Tower Operator, at its own cost and expense, shall make (or cause to be made) all Modifications to the Sites as may be required from time to time to meet in all material respects the requirements of applicable Laws.

(c) Access. Tower Operator agrees to maintain access roads to the Sites in such order and repair as would be required in accordance with tower industry standards and agrees not to take any action (except as required by Law, a Governmental Authority, a Ground Lease, a Collocation Agreement or any other agreement affecting the Site) that would materially diminish or impair any means of access to any Site existing as of the Effective Date. In the event that the applicable AT&T Lessor requires access to a Site but snow or some other obstruction on or in the access area is preventing or materially hindering access to the Site, and provided the Ground Lessor is not obligated to maintain access to such Site, Tower Operator shall use commercially reasonable efforts to arrange, at its sole cost and expense, to have such snow or other obstruction removed within 48 hours of notice therefrom from such AT&T Lessor. In the event that access to any Site is controlled by a Ground Lessor or other third party, Tower Operator will use commercially reasonable efforts to coordinate with such Ground Lessor or other third party to cause the applicable AT&T Lessor to have access consistent with this Section 11(c).

SECTION 12. Tower Operator Requirements for Modifications; Title to Modifications; Work on the Site.

(a) Subject to the requirements of this Section 12 (and the limitations set forth in Section 34(a)(ii)(D)-(E)), Tower Operator may from time to time make such Modifications as Tower Operator elects, including the addition or removal of land, construction, modification or addition to the Tower or other Improvements or any other structure or the reconstruction, replacement or alteration thereof; provided that Tower Operator shall provide not less than ten (10) Business Days’ notice to the applicable AT&T Lessor or AT&T Ground Lease Party if such Modification adversely affects such AT&T Lessor or AT&T Ground Lease Party. Notwithstanding anything to the contrary contained herein, in no event may Tower Operator make any Modification to, or materially adversely affecting, any AT&T Improvement or modify or replace any AT&T Communications Equipment except in the event of an Emergency as to which Tower Operator is not the cause or source (and, in such an Emergency, Tower Operator shall make reasonable efforts to notify the AT&T Lessors prior to taking such actions and shall reimburse AT&T Collocator for any damage caused by Tower Operator or its agents; provided that if (i) any of AT&T Lessor, AT&T Collocator or any other AT&T Group Member or (ii) any AT&T Communications Equipment or AT&T Improvements are determined to be the cause or source of an Emergency, AT&T Collocator shall be responsible and shall reimburse Tower Operator for all costs and expenses related to such Emergency). Title to each Modification shall without further act or instrument vest in the applicable AT&T Lessor or AT&T Ground Lease Party and be deemed to constitute a part of the Site and be subject to this Agreement if, but only if, such Modification is required pursuant to Section 6(a) of the MPL Site MLA or is a Non-Severable Modification; provided, however, if Tower Operator exercises its Purchase Option with respect to such Site, title to all Modifications will transfer to Tower Operator. Title to all other Modifications shall vest in Tower Operator.

-37-

(b) Whenever Tower Operator or any Tower Operator Indemnitee makes Modifications to any Site or installs, maintains, replaces or repairs any Tower Operator Equipment or Improvements, or permits Tower Subtenants (or any Tower Subtenant Related Party) to install, maintain, replace or repair any Tower Subtenant Communications Equipment or Tower Subtenant Improvement (collectively, the “Tower Operator Work”), the following provisions shall apply:

(i) No Tower Operator Work shall be commenced until Tower Operator has obtained all Governmental Approvals necessary for such Tower Operator Work, from all Governmental Authorities having jurisdiction with respect to any Site or such Tower Operator Work. Each AT&T Lessor shall reasonably cooperate with Tower Operator, at Tower Operator’s sole cost and expense, as is reasonably necessary for Tower Operator or a Tower Subtenant to obtain such Governmental Approvals.

(ii) No Tower Operator Work may be performed in violation of Section 12(a).

(iii) Tower Operator shall (or shall require Tower Subtenant to) commence and perform the Tower Operator Work in accordance with then-current tower industry standards.

(iv) Tower Operator shall require the Tower Operator Work to be done and completed in compliance in all material respects with all Laws.

(v) All Tower Operator Work shall be performed at Tower Operator’s or the subject Tower Subtenant’s sole cost and expense and Tower Operator or the subject Tower Subtenant shall be responsible for payment of same. Tower Operator or the subject Tower Subtenant 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 Tower Operator Work. Tower Operator or the subject Tower Subtenant shall promptly pay when due all costs and expenses incurred in connection with the Tower Operator Work. Tower Operator or the subject Tower Subtenant shall pay, or cause to be paid, all fees and Taxes required by Law in connection with the Tower Operator Work. Tower Operator may pass on any of the foregoing costs and expenses in whole or in part to a Tower Subtenant.

SECTION 13. Tower Operator’s Obligations With Respect to Tower Subtenants.

(a) Tower Subtenant Communications Equipment in Violation of Laws. If Tower Operator obtains knowledge that any Tower Subtenant has installed or operates any Communications Equipment in violation of any applicable Law, Tower Operator shall enforce all remedies available to it under the applicable Collocation Agreement or as otherwise provided by Law to cause such Tower Subtenant to come into compliance with all applicable Laws as promptly as practicable.

(b) Rights of Tower Subtenants under Collocation Agreements. Notwithstanding anything to the contrary contained herein, the obligations of Tower Operator

-38-

hereunder as to any Site are subject to any limitations imposed by any applicable Law and to the rights of any Tower Subtenant under any Collocation Agreement in existence as of the Effective Date at such Site. To the extent that any such Collocation Agreement or any applicable Law prohibits Tower Operator from performing the obligations of Tower Operator hereunder, then, for so long as such limitation is applicable, Tower Operator shall be required to perform such obligations only to the extent not so prohibited and shall have no liability with respect thereto to AT&T Lessors.

SECTION 14. Limitations on Liens.

(a) Other than as expressly permitted by the Transaction Documents, Tower Operator agrees that, during the Term, it shall not directly or indirectly, without the written consent of the applicable AT&T Lessor, which consent shall not be unreasonably conditioned, withheld or delayed, incur, grant or permit to exist (and shall cause its Affiliates, contractors and their subcontractors, and shall use commercially reasonable efforts to cause Tower Subtenants and their contractors and subcontractors, not to incur, grant or permit to exist) any Liens against any Site or any part of any Site (other than Tower Operator Permitted Liens). If any such Lien created or permitted by Tower Operator (other than Tower Operator Permitted Liens) is filed against all or any part of any Site without the applicable AT&T Lessor’s or AT&T Ground Lease Party’s prior written consent, or any Lien described in clauses (i), (ii) or (viii) of the definition of “Tower Operator Permitted Lien” ceases to be a Tower Operator Permitted Lien by reason of the commencement of a foreclosure, distraint, sale or similar proceeding, Tower Operator shall be required to cause such Lien to be discharged by payment, satisfaction or posting of bond within 30 days after Tower Operator has obtained knowledge of such Lien (and in any event prior to any loss or forfeiture) except as expressly permitted in connection with a contest of such Lien in accordance with Section 14(b). If Tower Operator fails to cause any Lien not being contested as provided in Section 14(b) (other than Tower Operator Permitted Liens) to be discharged within the permitted time and a Risk of Forfeiture exists as a result of such Lien, the applicable AT&T Lessor or AT&T Ground Lease Party may cause it to be discharged and may pay the amount of such Lien in order to do so, and shall be reimbursed therefor by Tower Operator within 10 days after such payment. For the avoidance of doubt, and notwithstanding anything to the contrary in this Agreement, nothing herein shall in any way affect or impair (i) Tower Operator’s ability to incur, grant or permit to exist any Liens on any revenue, rents, issues or profits derived from the Sites (including under or pursuant to any Collocation Agreements) or (ii) the ability of any parent company of Tower Operator to pledge any equity interests in Tower Operator.

(b) To the extent not prohibited under any applicable Ground Lease, Tower Operator may, at Tower Operator’s sole cost and expense, in its own name and on its own behalf or in the name of and on behalf of the applicable AT&T Lessor, diligently and 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 from such contest; provided, however, that if a Risk of Forfeiture exists by virtue of or by reason of such claim of Lien, such claim shall be complied with as promptly as practicable, but in any event prior to any loss or forfeiture. Each AT&T Lessor, at the sole cost and expense of Tower Operator, shall use commercially reasonable efforts to cooperate fully with Tower Operator in any such contest.

-39-

(c) Any Secured Tower Operator Loan (including any Mortgage executed in connection therewith) shall be subject to each and every term, covenant, condition, agreement, requirement, restriction and provision set forth in this Agreement. Tower Operator shall notify AT&T Lessors in writing promptly following the satisfaction, repayment or termination of any Secured Tower Operator Loan that has been afforded the protections set forth in Section 21.

SECTION 15. Tower Operator Indemnity; AT&T Lessor Indemnity; Procedure For All Indemnity Claims.

(a) Tower Operator Indemnity.

(i) Without limiting Tower Operator’s other obligations under this Agreement, Tower Operator agrees to indemnify, defend and hold each AT&T Indemnitee harmless from, against and in respect of any and all Claims (other than Claims that the subject of, or are addressed by, paragraphs (ii) through (iv) of this Section 15(a)) that arise out of or relate to:

(A) any default, breach or nonperformance by Tower Operator of its obligations and covenants under this Agreement;

(B) the (x) ownership or (y) use, operation, maintenance or occupancy (other than the use, operation, maintenance or occupancy by any AT&T Indemnitee), in each case, of any part of a Site from and after the Effective Date, including all obligations that relate to or arise out of any Ground Lease from and after the Effective Date;

(C) any work at a Site performed by or at the direction of a Tower Operator Indemnitee;

(D) the acts or omissions of a Tower Operator Indemnitee or any of its engineers, contractors or subcontractors; and

(E) 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 with Tower Operator and its Affiliates, agents, employees, engineers, contractors, subcontractors, licensees or invitees in connection with this Agreement.

Notwithstanding the foregoing, Tower Operator will (x) only be obliged to indemnify, defend and hold the AT&T Indemnitees harmless from, against and in respect of Claims arising from or relating to any default, breach or nonperformance of Section 2(d) (other than clause (A)(y) of the last sentence of Section 2(d)(i)) in the event that the Purchase Option with respect to the applicable Site is not exercised by the Tower Operator in accordance with the MPL and (y) not be obliged to indemnify, defend and hold the AT&T Indemnitees harmless from, against and in respect of Claims arising from or relating to any default, breach or nonperformance of any term of this Agreement that requires Tower Operator to comply in all respects with any applicable Law (including, for the avoidance of doubt, any applicable Environmental Law) or any Ground Lease if (1) Tower Operator complies with such Law or such Ground Lease, as applicable, in all

-40-

material respects and (2) no claims, demands, assessments, actions, suits, fines, levies or other penalties have been asserted against or imposed on AT&T Lessor by any Governmental Authority as a result of Tower Operator’s non-compliance in all respects with such Law or by the applicable Ground Lessor as a result of Tower Operator’s non-compliance in all respects with such Ground Lease.

(ii) In the event that (A) Tower Operator shall have extended a Ground Lease with respect to a Site beyond the applicable Site Expiration Outside Date, (B) Tower Operator shall not have exercised the Purchase Option with respect to such Site and (C) AT&T Collocator shall have vacated such Site, Tower Operator further agrees to indemnify, defend and hold each AT&T Indemnitee harmless from, against and in respect of all Claims, costs and expenses that are incurred by the applicable AT&T Lessor from and after the Site Expiration Outside Date for such Site until the earliest scheduled expiration of such Ground Lease (without giving effect to any further amendments, extensions or modifications thereof).

(iii) In the event that (A) Tower Operator shall enter into a new Collocation Agreement or extend an existing Collocation Agreement, in each case that extends beyond the applicable Site Expiration Outside Date of the Site to which such Collocation Agreement relates, (B) Tower Operator shall not have exercised the Purchase Option with respect to the Site to which such Collocation Agreement relates and (C) such Collocation Agreement is not on commercially reasonable terms with respect to the period following the Site Expiration Outside Date, Tower Operator further agrees to indemnify, defend and hold each AT&T Indemnitee harmless for such Collocation Agreement (without giving effect to any amendment, extension or modification thereof by any Person other than Tower Operator or any of its Affiliates), but only with respect to the period following the applicable Site Expiration Outside Date (and only if such agreement cannot be terminated by the applicable AT&T Lessor without cost or penalty).

(iv) In the event that Tower Operator does not exercise the Purchase Option with respect to any Purchase Site, Tower Operator shall indemnify, defend and hold the applicable AT&T Lessor or AT&T Ground Lease Party harmless for any losses incurred by such AT&T Lessor or AT&T Ground Lease Party as a result of the use of such Site by Tower Operator in a manner outside of the uses contemplated by this Agreement that materially impairs or adversely affects such AT&T Lessor’s or AT&T Ground Lease Party’s right, title and interest in, to and under such Site or in a manner that makes possible a claim of adverse possession by the public or a claim of implied dedication to the public with respect to such Site (it being understood, for the avoidance of doubt, that Tower Operator shall not have any obligation to monitor or control the use of any Site by AT&T Collocator or its Affiliates and shall not be required to indemnify, defend or hold such AT&T Lessor and AT&T Ground Lease Party harmless with respect to any losses or Claims arising from or relating to the use of any Site by AT&T Collocator or any of its Affiliates).

(v) Tower Operator further agrees to indemnify, defend and hold each AT&T Indemnitee harmless under any other provision of this Agreement which expressly provides that Tower Operator shall indemnify, defend and hold harmless any

-41-

AT&T Indemnitee with respect to the matters covered in such provision.

(b) AT&T Lessor Indemnity.

(i) Without limiting any AT&T Lessor’s other obligations under this Agreement, the AT&T Lessors agree, jointly and severally, to indemnify, defend and hold each Tower Operator Indemnitee harmless from, against and in respect of any and all Claims that arise out of or relate to:

(A) any default, breach or nonperformance of its obligations and covenants under this Agreement;

(B) any AT&T Indemnitee’s ownership, use, operation, maintenance or occupancy of any AT&T Communications Equipment or any portion of any Site (including the AT&T Collocation Space and any Reserved Property) in violation of the terms of the MPL Site MLA or any applicable Ground Lease;

(C) any work at a Site performed by or at the direction of an AT&T Indemnitee (but not including any work at any Site that Tower Operator is required to perform pursuant to this Agreement that AT&T Lessor elects to perform under Section 28);

(D) the acts or omissions of an AT&T Indemnitee or any of their respective engineers, contractors or subcontractors; and

(E) 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 with any AT&T Lessor or its agents, employees, engineers, contractors, subcontractors, licensees or invitees in connection with this Agreement.

(ii) AT&T Lessors further agree, jointly and severally, to indemnify, defend and hold each Tower Operator Indemnitee harmless under any other provision of this Agreement which expressly provides that any AT&T Lessor shall indemnify, defend and hold harmless any Tower Operator Indemnitee with respect to the matters covered in such provision.

(c) Indemnification Claim Procedure.

(i) Any Indemnified Party shall promptly notify the Party or Parties alleged to be obligated to indemnify (the “Indemnifying Party”) in writing of any relevant pending or threatened Claim by a third party (a “Third Party Claim”), describing in reasonable detail the facts and circumstances with respect to the subject matter of the Claim; provided, however, that delay in providing such notice shall not release the Indemnifying Party from any of its obligations under Section 15(a) or Section 15(b), except to the extent (and only to the extent) the delay actually and materially prejudices the Indemnifying Party’s ability to defend such Claim.

-42-

(ii) The Indemnifying Party may assume and control the defense of any Third Party Claim with counsel selected by the Indemnifying Party that is reasonably acceptable to the Indemnified Party by accepting its obligation to defend in writing and agreeing to pay defense costs (including reasonable out-of-pocket attorney’s fees and expenses) within 30 days of receiving notice of the Third Party Claim. If the Indemnifying Party declines, fails to respond to the notice, or fails to assume defense of the Third Party Claim within such 30-day period, then the Indemnified Party may control the defense and the Indemnifying Party shall pay all reasonable out-of-pocket defense costs as incurred by the Indemnified Party. The Party that is not controlling the defense of the Third Party Claim shall have the right to participate in the defense and to retain separate counsel at its own expense. The Party that is controlling the defense shall use reasonable efforts to inform the other Party about the status of the defense. The Parties shall cooperate in good faith in the defense of any Third Party Claim. Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to assume the defense of any Third Party Claim (and shall be liable for the reasonable out-of-pocket fees and expenses of counsel incurred by the Indemnified Party in defending such Third Party Claim) if the Third Party Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the Indemnified Party that the Indemnified Party reasonably determines, after conferring with its outside counsel, cannot reasonably be separated from any related claim for money damages. If such equitable relief or other relief portion of the Third Party Claim can be so separated from that for money damages, the Indemnifying Party shall be entitled to assume the defense of the portion relating to money damages.

(iii) The Indemnifying Party shall not consent to a settlement of, or the entry of any judgment arising out of or in connection with, any Third Party Claim, without the consent of any Indemnified Party; provided, however, that the Indemnified Party shall not withhold its consent if such settlement or judgment involves solely the payment of money, without any finding or admission of any violation of Law or admission of any wrongdoing. The Indemnifying Party shall pay or cause to be paid all amounts arising out of such settlement or judgment concurrently with the effectiveness of such settlement and obtain, as a condition of any settlement or judgment, a complete and unconditional release of each relevant Indemnified Party from any and all liability in respect of such Third Party Claim.

(iv) For indemnification Claims other than Third Party Claims, the Indemnified Party promptly shall notify the Indemnifying Party in writing of any Claim for indemnification, describing in reasonable detail the basis for such Claim. Within 30 days following receipt of this notice, the Indemnifying Party shall respond, stating whether it disputes the existence or scope of an obligation to indemnify the Indemnified Party under this Section 15. If the Indemnifying Party does not respond within 30 days, the Indemnified Party shall send a second notice to the Indemnifying Party, marked at the top in bold lettering with the following language: “A RESPONSE IS REQUIRED WITHIN FIVE (5) BUSINESS DAYS OF RECEIPT OF THIS NOTICE PURSUANT TO THE TERMS OF A MASTER PREPAID LEASE WITH THE UNDERSIGNED AND FAILURE TO RESPOND SHALL RESULT IN YOUR RIGHT TO OBJECT BEING WAIVED” and the envelope containing the request must be marked

-43-

“PRIORITY”. If the Indemnifying Party does not notify the Indemnified Party within such 5 Business Days after the receipt of such second notice that the Indemnifying Party disputes its liability to the Indemnified Party under Section 15(a) or Section 15(b), as applicable, such Claim specified by the Indemnified Party in such notice shall be conclusively deemed a liability of the Indemnifying Party under Section 15(a) or Section 15(b), as applicable, and the Indemnifying Party shall pay the amount of such Claim to the Indemnified Party on demand or, in the case of any notice in which the amount of the Claim (or any portion thereof) is estimated, on such later date when the amount of such claim (or such portion thereof) becomes finally determined. If the Indemnifying Party timely disputes the existence or scope of an obligation to indemnify for the Claim, it shall explain in reasonable detail the basis for the dispute. If the Parties disagree on the scope or existence of an indemnification obligation for the Claim, management representatives of the Indemnified Party and the Indemnifying Party shall meet or confer by telephone within 20 Business Days in an attempt in good faith to resolve such dispute.

For each Site, Tower Operator shall deliver to each AT&T Lessor a certificate or certificates of insurance evidencing the existence of all required insurance and applicable endorsements with respect to each Site that Tower Operator is required to maintain hereunder, such delivery to be made promptly after such insurance is obtained (but not later than the Effective Date) and prior to the expiration date of any such insurance.

exercise its Purchase Option with respect to all (but not less than all) of the applicable Purchase Sites comprising the applicable Tranche of Sites as of the applicable Purchase Option Closing Date, for the Option Purchase Price attributable to such Purchase Sites (and on the other terms and subject to the conditions specified in this Agreement), by submitting to the Option Sellers, no earlier than two years and no later than 120 days prior to the applicable Purchase Option Closing Date, a written offer to purchase all such Purchase Sites in accordance with the terms hereof; provided, however, that the only condition to such exercise shall be that both on the applicable date of submission of such written offer and the Purchase Option Closing Date, this Agreement shall not have been terminated. The Option Sellers shall be obligated to sell, and AT&T Guarantor shall cause the Option Sellers to sell, and Tower Operator shall be obligated to buy, all such Purchase Sites hereunder at a single closing to be held on and effective as of the applicable Purchase Option Closing Date.

The “Option Purchase Price” means, with respect to each Tranche of Sites on the applicable Purchase Option Closing Date, the purchase price that is set forth opposite such Tranche of Sites on Exhibit E hereto, multiplied by a fraction (i) the numerator of which is equal to (A) the number of Purchase Sites comprising such Tranche of Sites on the applicable Purchase Option Closing Date plus (B) the number of Sites included in such Tranche of Sites on the Effective Date and which were transferred to Tower Operator in accordance with Section 9(b)(i); provided that the Sites described above in clause (i)(B) shall only be included in the numerator if the Tower (x) included in the transfer of such Site in accordance with Section 9(b)(i) is still located on such Site, (y) is still in active operation on such Site and (z) is still owned by Tower Operator, in each case as of the applicable Purchase Option Closing Date and (ii) the denominator of which is equal to the number of Sites comprising such Tranche of Sites on the Effective Date. At the closing of such sale, each of the Option Sellers shall transfer or cause to be transferred its applicable Purchase Sites, at Tower Operator’s cost and expense, to Tower Operator and the Term as to the Purchase Sites shall end. Risk of loss for the Purchase Sites purchased pursuant to this Section 20 shall pass from the Option Sellers to Tower Operator upon payment of the applicable purchase price by Tower Operator to the Option Sellers.

(c) Transfer by Option Sellers. Any transfer of Purchase Sites by the Option Sellers to Tower Operator pursuant to this Section 20 shall include the following (the “Transferred Property” of the Purchase Sites):

(i) (A) An assignment of the Option Sellers’ interest in any Ground Lease and other related rights for such Purchase Site (which shall contain an assumption by Tower Operator of all of the obligations of such Option Sellers under such Ground Lease and an agreement by Tower Operator to indemnify such Option Sellers and each other AT&T Indemnitee from all Claims related to such obligations) or the transfer of fee simple title or other applicable ownership interest of Option Sellers at each Purchase Site and (B) a sale, conveyance, assignment, transfer and delivery of all such Option Sellers’ right, title and interest in, to and under the applicable Included Property (other than AT&T Improvements or AT&T Communications Equipment) and all appurtenances thereto;

-51-

(ii) To the extent not included in clause (i) above, and to the extent legally transferable (and, if such rights cannot be transferred to Tower Operator, such rights shall be enforced by the Option Sellers at the direction of and for the benefit of the Tower Operator for a period of three (3) years from the applicable Purchase Option Closing Date), a transfer of all rights of such Option Sellers under or pursuant to warranties, representations and guarantees made by suppliers or manufacturers in connection with such Purchase Site (other than AT&T Improvements or AT&T Communications Equipment), but excluding any rights to receive amounts under such warranties, representations and guarantees representing reimbursements for items paid by such Option Sellers; and

(iii) To the extent legally transferable (and, if such rights, claims, credits and causes of action cannot be transferred to Tower Operator, such rights, claims, credits and causes of action shall be enforced by the Option Sellers at the direction of and for the benefit of the Tower Operator for a period of three (3) years from the applicable Purchase Option Closing Date), a transfer of all known and unknown rights, claims, credits, causes of action or rights to commence any causes of action or rights of setoff of each such Option Seller against third parties relating to such Purchase Site (other than AT&T Improvements or AT&T Communications Equipment) 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 such Option Sellers.

(d) Evidence of Transfer. Each of the Option Sellers and Tower Operator shall enter into, and AT&T Guarantor shall cause the Option Sellers to enter into, assignments, deeds (with warranties of title as to actions by such Option Seller and its Affiliates), bills of sale and such other documents and instruments as the other may reasonably request to evidence any transfer of such Purchase Sites.

(e) Transfer Taxes. Any Transfer Taxes incurred in connection with the transfer of Purchase Sites by the Option Sellers to Tower Operator pursuant to this Section 20 shall be governed by Section 22(d).

(f) Permitted Liens. Any transfer of a Purchase Site by any Option Seller to Tower Operator or its designee pursuant to this Agreement shall be subject to all Permitted Liens applicable to such Purchase Site and any Liens created or incurred after the Effective Date (other than any Liens created or incurred by, or consented to by, any of the Option Sellers or their respective Affiliates or any of their respective Representatives).

(g) Actions by Option Sellers. The Option Sellers shall not, and AT&T Guarantor shall not permit the Option Sellers or any of their Affiliates to, (i) take or fail to take any action which action or omission could reasonably be expected to impair or adversely affect the Option Seller’s right, title and interest in, to and under any Purchase Site (including the Transferred Property thereof), (ii) take any action which could reasonably be expected to diminish the expected residual value of any Purchase Site (including the Transferred Property thereof) in any material respect or (iii) take any action which could reasonably be expected to shorten the expected remaining economic life of any Purchase Site (including the Transferred

-52-

Property thereof), in each case, unless such action or failure to act by the Option Sellers or any of their Affiliates is expressly authorized by the terms and conditions of this Agreement and the Transaction Documents (by way of example, the election by AT&T Collocator not to extend the term of the MPL Site MLA beyond its initial 10 year term, in and of itself, shall not be deemed to have violated this covenant, solely as a result of such election). The Option Sellers shall not, and AT&T Guarantor shall not permit the Option Sellers or any of their Affiliates to, sell, dispose of, transfer, lease, license or encumber any of their interests in any of the Purchase Sites (including the Included Property), other than Permitted Liens or in compliance with Section 18(b). The Option Sellers shall take, and AT&T Guarantor shall cause the Option Sellers and their respective Affiliates to take, all actions necessary, appropriate or desirable, or reasonably requested from time to time by Tower Operator, to preserve and protect the Option Sellers’ right, title and interest in, to and under the Purchase Sites (including the Included Property thereof).

(h) Further Assurances. AT&T Guarantor and the Option Sellers, at their cost and expense, shall use their reasonable best efforts, beginning on the date that is 6 months prior to the applicable Purchase Option Closing Date, to obtain any consent or waiver required to give effect to the sale of the Purchase Sites upon the exercise of the Purchase Option. In the event that any Option Seller is unable to obtain any consent or waiver required to give effect to the sale of any Purchase Site by the applicable Purchase Option Closing Date, and such Purchase Site cannot be transferred without violating the terms of the applicable Ground Lease, then, upon payment of the full Option Purchase Price on the applicable Purchase Option Closing Date (including with respect to such Site), the Option Sellers shall appoint, and AT&T Guarantor shall cause the Option Sellers to appoint, Tower Operator, in perpetuity, as the exclusive operator of the Included Property of such Purchase Site. In furtherance of the foregoing, the Option Sellers and Tower Operator shall enter into documentation (including applicable powers of attorney) that is reasonably acceptable to Tower Operator to provide for Tower Operator’s management rights with respect to such Purchase Site, which documentation shall grant and confer to Tower Operator all rights and privileges (including all rights to receive the revenue derived from such Site and all rights and powers with respect to the operation, maintenance, leasing and licensing of such Site) granted or conferred to Tower Operator pursuant to this Agreement in respect of a Managed Site, but shall otherwise treat Tower Operator as if Tower Operator was the owner of such Purchase Site and shall not impose on Tower Operator any of the covenants or restrictions imposed upon it by this Agreement and the Transaction Documents.

(i) Indemnity. Effective upon the closing of any transfer of Purchase Sites pursuant to this Section 20, Tower Operator shall indemnify, defend and hold each AT&T Indemnitee harmless from, against and in respect of any and all Claims to the extent resulting from, arising out of or relating to Post-Closing Liabilities with respect to the Transferred Property of such transferred Purchase Sites from and after the applicable Purchase Option Closing Date, pursuant to the procedures set forth in Section 15(c), or, solely with respect to such indemnity claims for Taxes, pursuant to the procedures set forth in Section 34(a). At the applicable AT&T Lessor’s or AT&T Ground Lease Party’s request, Tower Operator shall execute such instruments or documents as may be reasonably necessary to give effect to the indemnity described in this Section 20(i).

(j) Deliveries if Purchase Option Not Exercised. If Tower Operator does not exercise its Purchase Option with respect to any Site, Tower Operator shall deliver to the

-53-

applicable AT&T Lessor or AT&T Ground Lease Party, promptly after the applicable Site Expiration Date, all documents and information as reasonably requested by the applicable AT&T Lessor or AT&T Ground Lease Party to allow such AT&T Lessor or AT&T Ground Lease Party to operate and manage such Site.

(k) Site Access. Upon the transfer of any Purchase Sites to Tower Operator pursuant to this Section 20, Tower Operator shall grant to the AT&T Collocator as to each Purchase Site a non-exclusive right and easement (over the surface of the Purchase Site) to access any structures (including Shelters and cabinets) on such Purchase Site owned and used, and intended for use, exclusively by AT&T Collocator or any Affiliate of AT&T Collocator other than in the Collocation Operations, in each case on such Purchase Site as of the Effective Date (without regard to any demolition in connection with the planned replacement thereof or substitution therefor with a similar structure and any period of construction or restoration thereof) or any replacement thereof or substitution therefor with a similar structure, at such times (on a 24-hour, seven day per week basis unless otherwise limited by the Ground Lease, but subject to giving Tower Operator at least one Business Day’s prior notice or, in the case of an Emergency, as much notice as is practicable, in each case in accordance with Tower Operator’s standard process), to such extent, and in such means and manners (on foot or by motor vehicle, including trucks and other heavy equipment), as AT&T Collocator (and its authorized contractors, subcontractors, engineers, agents, advisors, consultants, representatives, or other persons authorized by AT&T Collocator) deems reasonably necessary in connection with its use, operation and maintenance of such structures, in each case for as long as AT&T Collocator or such Affiliate maintains such structure or any replacement thereof or substitution therefor with a similar structure.

SECTION 21. Tower Operator Lender Protections.

(a) Tower Operator Lender Protections. If AT&T Lessors are given written notice from Tower Operator specifying the name and address of the Tower Operator Lender, or its servicing agent and the title of an officer or other responsible individual charged with processing notices of the type required under this Section 21, then the following provisions shall apply with respect to such Tower Operator Lender for so long as any Secured Tower Operator Loan remains unsatisfied:

(i) The Tower Operator Lender shall not be bound by any modification or amendment of this Agreement in any respect so as to materially increase the liability of Tower Operator hereunder or materially increase the obligations or materially decrease the rights of Tower Operator without the prior written consent of the Tower Operator Lender, which consent shall not be unreasonably conditioned, withheld or delayed.

(ii) Further, this Agreement may not be surrendered or terminated other than in compliance with the provisions of this Section 21. Any such modification, amendment, surrender or termination not in accordance with the provisions of this Section 21 shall not be binding on any such Tower Operator Lender or any other Person who acquires title to its foreclosed interest.

-54-

(b) Notice and Cure Rights.

(i) AT&T Lessors, upon serving Tower Operator with any notice of default under the provisions of, or with respect to, this Agreement, shall also serve a copy of such notice upon the Tower Operator Lender (in the same manner as required for notices to Tower Operator) at the address specified herein, or at such other address that a Tower Operator Lender designates in writing to AT&T Lessors.

(ii) Without limiting any AT&T Lessor’s rights under this Agreement to cure any event of default or breach by Tower Operator under this Agreement, in the event of a default or breach by Tower Operator under this Agreement, the Tower Operator Lender shall have the right, but not the obligation, to remedy such event, or cause the same to be remedied, within 10 days after the expiration of all applicable grace or cure periods provided to Tower Operator in this Agreement, in the event of a monetary default or breach, or within 60 days after the expiration of all applicable grace or cure periods provided to Tower Operator in this Agreement in the event of any other breach or default, and AT&T Lessors shall accept such performance by or at the instance of the Tower Operator Lender as if the same had been made by Tower Operator; provided, however, that if any such non-monetary default or breach that is capable of cure requires Tower Operator Lender to acquire possession of the Tower Operator’s interest in the Sites that are the subject of such breach or default, such period shall be extended for such reasonable period as may be required to obtain such possession and cure such default or breach; provided, however, that during such extended period, Tower Operator Lender must continue to cure other defaults and breaches in accordance with the provisions of this Section 21(b)(ii).

(iii) In the event of the termination of this Agreement prior to the expiration of the Term of this Agreement as provided herein for any reason (excluding Tower Operator’s failure to cure under (ii) above and terminations under Sections 4(d)(iv), 35 and 36, but including pursuant to Section 365 of the Bankruptcy Code, as amended from time to time, including any successor legislation thereto), AT&T Lessors shall serve upon Tower Operator Lender written notice that this Agreement has been terminated, together with a statement of any and all sums due under this Agreement and of all breaches and events of default under this Agreement, if any, then known to AT&T Lessors. During the ten (10) Business Days following Tower Operator Lender’s receipt from AT&T Lessors of such written notice that this Agreement has been terminated, Tower Operator Lender shall have the option, which option must be exercised by Tower Operator Lender’s delivering notice to AT&T Lessors within the aforementioned ten (10) Business Day period, to cure any such Tower Operator breaches or Tower Operator events of default (and any Tower Operator breaches or Tower Operator events of default not susceptible of being cured by the Tower Operator Lender shall be deemed to have been waived) and the right (subject to such cure) to enter into a new lease (the “New Lease”) (A) effective as of the date of termination of this Agreement, (B) for the remainder of what otherwise would have been the Term of this Agreement but for such termination, (C) at and upon all the agreements, terms, covenants, and conditions of this Agreement (provided that Tower Operator Lender shall not have any obligation to pay AT&T Lessors Rent or Pre-Lease Rent), and (D) including any applicable right to

-55-

exercise the Purchase Option under Section 20. Upon the execution and delivery of a New Lease under this Section 21, all Collocation Agreements and other agreements which theretofore may have been assigned to the AT&T Lessor (or reverted back to such AT&T Lessor as a matter of Law) thereupon shall be assigned and transferred, without recourse, representation or warranty, by such AT&T Lessor to the lessee named in such New Lease.

(iv) Any notice or other communication that a Tower Operator Lender desires or is required to give to or serve upon AT&T Lessors shall be made in the same manner as required for notices to AT&T Lessors in accordance with the provisions of this Agreement at the address set forth herein or such other address as AT&T Lessors may provide to Tower Operator Lender from time to time.

(c) Participation in Certain Proceedings and Decisions. Any Tower Operator Lender shall have the right, subject to Tower Operator’s consent, to intervene and become a party, but only with respect to Tower Operator’s involvement in any Arbitration, litigation, condemnation or other proceeding affecting this Agreement to the extent of its security interest herein. Tower Operator’s right to make any election or decision under this Agreement that is required or permitted to be made by Tower Operator with respect to the negotiation or acceptance of any Award or insurance settlement shall be subject to the prior written approval of such Tower Operator Lender. AT&T Lessor shall be entitled to rely (if acting in good faith) upon any notice or other communication from Tower Operator Lender or Tower Operator without verifying the authority of Tower Operator Lender or Tower Operator to act with respect to any such matter.

(d) No Merger. Without the written consent of each Tower Operator Lender, the leasehold interest created by this Agreement shall not merge with the fee interest in all or any portion of the Sites, notwithstanding that the fee interests and the leasehold interests are held at any time by the same Person.

(e) Encumbrances on Personal Property and Subleases. In addition to the rights granted in Section 18(a), each AT&T Lessor hereby consents to Tower Operator’s grant, if any, to any Tower Operator Lender of a security interest in the personal property owned by Tower Operator and located at the Sites and a collateral assignment of subleases of the interest of Tower Operator in all or any portion of the Sites and the revenue, rents, issues and profits derived therefrom (including under or pursuant to any Collocation Agreements), if any, and a pledge of any equity interests in Tower Operator. Each AT&T Lessor agrees that any interest that such AT&T Lessor may have in such personal property (but not its interest in the Included Property or this Agreement), whether granted pursuant to this Agreement or by Law, shall be subordinate to the interest of any Tower Operator Lender.

(f) Notice of Default Under any Secured Tower Operator Loan. Tower Operator shall promptly deliver to AT&T Lessors a true and correct copy of any notice of default, notice of acceleration or other notice regarding a default by Tower Operator under any documents comprising a Secured Tower Operator Loan after the receipt of such notice by Tower Operator.

-56-

(g) Casualty and Condemnation Proceeds. Notwithstanding anything in this Agreement to the contrary, in the event of any casualty to or condemnation of any Site or any portion thereof during such time that any Secured Tower Operator Loan remains unsatisfied, the Tower Operator Lender shall be entitled to receive all insurance Proceeds or condemnation awards (up to the amount of the indebtedness secured by the Secured Tower Operator Loan) otherwise payable to Tower Operator and apply same to restoration of the Included Property in accordance with the provisions of this Agreement (to the extent required by the terms of this Agreement); provided, however, that if the Included Property is not required to be restored pursuant to the terms of this Agreement, such Proceeds may be applied to the Secured Tower Operator Loan. Upon the Tower Operator Lender’s request, the name of such Tower Operator Lender may be added to the “Loss Payable Endorsement” of any and all insurance policies required to be carried by Tower Operator hereunder.

(h) Other. Notwithstanding any other provision of this Agreement to the contrary, (i) AT&T Lessors shall not be obligated to provide the benefits and protections afforded to Tower Operator Lenders in this Section 21 to more than three Tower Operator Lenders at any given time and (ii) in no event whatsoever shall there be any subordination of this Agreement or the rights and interests of AT&T Lessors under this Agreement or in and to the Included Property, or of the rights and interests of AT&T Collocator or its Affiliates under the MPL Site MLA or in and to the AT&T Collocation Space by virtue of any Mortgage granted by Tower Operator to any Tower Operator Lender and each Tower Operator Lender shall, upon request, confirm such fact in writing. If there is more than one Tower Operator Lender subject to the provisions of this Section 21, except as otherwise jointly directed in writing by such Tower Operator Lenders, AT&T Lessors shall recognize the Tower Operator Lender exercising rights afforded by this Section 21, whose Secured Tower Operator Loan is most senior in lien (unless a Tower Operator Lender junior in lien requires that the holder thereof have a superior entitlement to such rights, and the other Tower Operator Lender senior in lien shall agree in writing to such request, in which event such recognition shall be of the holder of that Secured Tower Operator Loan); provided, however, that such Tower Operator Lender shall have complied with the provisions of this Section 21; provided, further, that AT&T Lessors shall have no obligation to determine which Tower Operator Lender is indeed senior in lien and shall have no liability to any Tower Operator Lender for an erroneous determination if AT&T Lessors attempt to make such a determination so long as such determination is made in good faith based upon the evidence and information of lien priority provided to AT&T Lessors by the Tower Operator Lenders. Each Tower Operator Lender which has complied with the notice requirements of this Section 21 shall have the right to appear in any arbitration or other material proceedings arising under this Agreement and to participate in any and all hearings, trials and appeals in connection therewith, but only to the extent related to the rights or obligations of Tower Operator in the matter that is the subject of the arbitration or proceedings or to protect the security interest of Tower Operator in the Included Property.

(i) Subordination of Mortgages. All Mortgages that at any time during the Term of this Agreement may be placed upon a Site or any portion of a Site and all documents and instruments evidencing and securing any Secured Tower Operator Loan secured by such Mortgages shall be subject and subordinate to the terms and conditions hereof.

-57-

(j) Estoppel Certificate. From time to time upon request of a Tower Operator Lender (but not more than once in any one year period), AT&T Lessors shall execute and deliver to such Tower Operator Lender an estoppel certificate with respect to this Agreement in a form reasonably acceptable to AT&T Lessors and Tower Operator Lender stating, if true, that as of the date of such estoppel certificate: (1) this Agreement is in full force and effect and has not been assigned, modified or amended (or, if it has, then specifying the dates and terms of any such assignment or amendment) and (2) Tower Operator is not in default under this Agreement to the knowledge of AT&T Lessors or, if such is not the case, stating the nature of each such default of which AT&T Lessor have knowledge.

(k) Notification of Termination. Tower Operator shall notify AT&T Lessors in writing immediately upon the satisfaction repayment or termination of any Secured Tower Operator Loan.

SECTION 22. Taxes; Fees.

(a) Subject to Section 20(e), Section 22(b), Section 22(c), Section 22(d) and Section 34(b), and except as provided for below, Tower Operator shall be responsible for and shall pay, as additional rent hereunder, all Taxes upon or with respect to any action taken by, or the business activities of, Tower Operator, Tower Operator Affiliates, Tower Operator Lender and any Tower Subtenant in connection with the acquisition, purchase, sale, financing, leasing, subleasing, maintenance, Modification, repair, redelivery, alteration, insuring, control, use, operation, delivery, possession, repossession, location, storage, refinancing, refund, transfer of title, registration, re-registration, transfer of registration, return or other disposition of any of the Included Property or any portion of such Included Property, or interest in such Included Property. Tower Operator shall receive any refunds for Taxes paid by Tower Operator pursuant to this Agreement. Notwithstanding the foregoing, Tower Operator shall not be required to pay any Taxes payable with respect to a Site, if the applicable Ground Lease provides that the Ground Lessor is responsible for such Taxes without pass-through to the applicable ground lessee and the Ground Lessor actually pays any such Taxes. If the Ground Lessor does not pay any such Taxes and either Party becomes aware of it, the Parties shall, at Tower Operator’s expense, cooperate and use commercially reasonable efforts to cause the Ground Lessor to pay such Taxes.

(b) In the taxable periods occurring during the Term as to any Site, any Taxes for which Tower Operator is responsible under this Section 22 and that are calculated or assessed on the basis of a time period any portion of which is not included within the Term as to such Site (e.g., Property Taxes assessed annually) shall be prorated proportionately between the applicable AT&T Group Member and Tower Operator based on the number of days in each such period during the time period of assessment. Tower Operator shall pay to the applicable AT&T Group Member Tower Operator’s proportionate share of such Taxes for any such partial year of the Term. Tower Operator’s obligations for Taxes under this Section 22 shall be limited to that proportionate amount of such Taxes attributable to the period during which this Agreement is in effect with respect to such Site; provided, however, that any Taxes resulting from special assessments or appraisals of any Site occurring during the period during which this Agreement is in effect shall be the sole responsibility of Tower Operator. Any other Taxes that are not calculated or assessed on the basis of a time period, but for which Tower Operator is responsible

-58-

under this Section 22 or Section 34(b), shall be prorated using a fair and equitable proration method that considers, among other things, the basis upon which such Taxes are assessed.

(c) Notwithstanding anything to the contrary herein (other than Section 34(g)), the Parties agree as follows with respect to Property Taxes payable during the Term of this Agreement: (i) AT&T Lessors or the applicable AT&T Group Member shall pay all Property Taxes on a timely basis to the appropriate Governmental Authority and Tower Operator shall have no responsibility for Property Taxes other than the payment of (A) the Tower Operator Property Tax Charge to the applicable AT&T Lessor and (B) any Property Taxes with respect to any personal property installed by Tower Operator on the Included Property; and (ii) for each calendar year, or portion thereof, that is included in the Term as to each Site, Tower Operator shall pay to the applicable AT&T Lessor the Tower Operator Property Tax Charge on or before July 1 of the respective calendar year; provided that if the Effective Date is after July 1, the payment for the first calendar year (or portion thereof) shall be made on the Effective Date; provided, however, that if the Term ends prior to July 1, the payment for the final year shall be made on the last day of the Term. Notwithstanding the foregoing, the AT&T Lessors or the applicable AT&T Group Member shall not be required to pay any Property Taxes payable with respect to a Site, if the applicable Ground Lease provides that the Ground Lessor is responsible for such Property Taxes without pass-through to the applicable ground lessee and the Ground Lessor actually pays any such Taxes. If the Ground Lessor does not pay any such Property Taxes and either Party becomes aware of it, the Parties shall, at Tower Operator’s expense, cooperate and use commercially reasonable efforts to cause the Ground Lessor to pay such Taxes. The AT&T Lessors, Tower Operator and the applicable AT&T Group Member shall cooperate with each other, and make available to each other such information as shall reasonably be necessary, in connection with the preparation of tax returns for Property Taxes and any audit or judicial or administrative proceeding relating to the same. To the extent an AT&T Group Member, other than AT&T Lessors or AT&T Collocator, has an obligation under this Section 22, AT&T Collocator shall cause such AT&T Group Member to perform such obligation. “Tower Operator Property Tax Charge” shall mean an amount equal to $1,769.00 per Site per annum (prorated for partial years).

(d) All sales, use, license, value added, documentary, stamp, gross receipts, registration, real estate transfer, conveyance, excise, recording and other similar Taxes and fees (“Transfer Taxes”) imposed as a result of the transactions contemplated by this Agreement shall be borne equally by the AT&T Lessors, on the one hand, and Tower Operator, on the other hand. For the avoidance of doubt, Tower Operator shall have no responsibility for any Transfer Taxes with respect to a Site imposed with respect to transfers exclusively between AT&T Group Members. To the extent permitted by applicable Law, Tower Operator shall prepare and duly and timely file all Tax returns in respect of such Transfer Taxes and all Tax returns where no Tax is due, but filing is required as a result of the transactions contemplated by this Agreement. Tower Operator shall promptly notify the AT&T Lessors if Tower Operator is not permitted by applicable Law to file any such return. The AT&T Lessors shall prepare and timely file all Tax returns in respect of Transfer Taxes that Tower Operator is not permitted to file under applicable Law. Prior to the filing of any Tax return in respect of Transfer Taxes, the filing Party shall provide such return and a calculation of the associated Transfer Taxes (if any) to the non-filing Party for the non-filing Party’s review and approval, which approval shall not be unreasonably conditioned, withheld or delayed. Where a Party remits Transfer Taxes to the applicable Taxing

-59-

Authority, the other Party shall reimburse the portion of such Transfer Taxes for which such other Party is responsible to the first mentioned Party by the earlier of 30 days after the date such Taxes are remitted to the taxing authority or 30 days after the filing due date of the applicable Tax return. The Tax liability and payment provisions of this Section 22(d) shall survive until the expiration of the longest applicable period of limitations. To the extent that any Party fails to timely reimburse the other Party for any Transfer Taxes paid by such other Party, the Parties agree that such other Party shall be entitled to offset such unpaid reimbursements against any other amounts due to it. The AT&T Lessors and Tower Operator agree to cooperate in good faith in order to take actions to minimize, within the fullest extent of the Law, the application or imposition of Taxes imposed on the transactions contemplated by this Agreement, which may include, for example, providing documentation to qualify for exemption from any applicable Tax or agreeing to cooperate in good faith to resolve an audit by a Taxing Authority involving the operation or application of this Agreement.

(e) Bulk Sales. Tower Operator and the AT&T Lessors hereby waive compliance by Tower Operator and the AT&T Lessors with the provisions of the “bulk sales,” “bulk transfer” and similar Laws.

(f) Fees. Unless specified in this Agreement (including the exhibits hereto), no unilateral fees or additional costs or expenses are to be applied by either Party to the other Party, including, but not limited to, the review of plans, structural analyses, consents, the provision of documents or other communications between the Parties.

SECTION 23. Utilities.

The rights and obligations of AT&T Collocator with respect to the use and payment of utilities and similar services to any Site shall be as set forth in the MPL Site MLA. Except as otherwise provided in the MPL Site MLA, (i) Tower Operator shall be responsible for the provision and payment of utilities and similar services used at any Site and (ii) AT&T Lessors shall have no obligation to make arrangements for or to pay any charges for connection or use of utilities and similar services to any Site, including electricity, telephone, power, and other utilities.

SECTION 24. Compliance with Law; Governmental Permits.

(a) Tower Operator shall, at its own cost and expense, obtain and maintain in effect all Governmental Approvals required or imposed by Governmental Authorities. Tower Operator shall comply with all applicable Laws in connection with the operation and maintenance of the Included Property of each Site (including the Tower on such Site). Without limiting the generality of the two immediately preceding sentences, Tower Operator shall maintain and repair at each Site in compliance with applicable Law (i) any ASR signs and any radio frequency exposure barriers and signs, including caution, notice, information or alert signs and (ii) any AM detuning equipment and, if required but not present at a Site, provide any necessary AM detuning equipment so that such Site complies with applicable Law. Tower Operator shall conduct annual inspections of all Sites with lighted Towers of such AT&T Lessor; provided that until the requisite waiver from the FCC has been obtained by the applicable AT&T Lessor, Tower Operator shall conduct quarterly inspections of all Sites with lighted Towers of

-60-

such AT&T Lessor. AT&T Collocator shall, at its own cost and expense, comply with all applicable Laws in connection with its use of each Site. Each AT&T Lessor agrees, promptly after the conversion of the Tower monitoring system at the Sites to Tower Operator’s network operations center, to petition the FCC to waive its rights to quarterly inspection of all lighted Towers of such AT&T Lessor for which such waiver has not already been obtained. Tower Operator shall not commence any work at a Site until all required Government Authorizations necessary to perform that work have been obtained, as provided by Section 12(b).

(b) Tower Operator shall, at Tower Operator’s cost and expense, obtain and maintain in effect all Governmental Approvals from the FAA and FCC relating to the operation and maintenance of each Site. To the extent Tower Operator and the AT&T Lessors disagree about the applicability of, or compliance with, Laws relating to FAA marking and lighting issues or FCC ASR or NEPA issues (whether discussed in this Section 24 or any other section of this Agreement), then the Parties shall adopt the approach consistent with industry practices and procedures. Tower Operator shall, at Tower Operator’s cost and expense, provide the AT&T Lessors with copies of all Governmental Approvals from the FAA and FCC.

(c) Tower Operator shall, at its own cost and expense, reasonably cooperate with AT&T Collocator or its Affiliates in their efforts to obtain and maintain in effect any Governmental Approvals from the FCC and to comply with any Laws applicable to the AT&T Communications Equipment and the AT&T Collocation Space. Without limiting the generality of the immediately preceding sentence, Tower Operator shall, at its own cost and expense and in a commercially reasonable time period, provide to AT&T Collocator any documentation in its possession or control that may be necessary for or reasonably requested by AT&T Collocator to comply with all FCC reporting requirements relating to the AT&T Communications Equipment and the AT&T Collocation Space.

(d) Notwithstanding anything herein to the contrary, Tower Operator shall have no obligation to provide any information necessary for AT&T Lessor or AT&T Collocator to obtain any Governmental Approval relating to the AT&T Communications Equipment itself (e.g., FCC type certification).

(e) Each AT&T Lessor shall reasonably cooperate with Tower Operator in Tower Operator’s efforts to provide information required by Governmental Authorities and to comply with all Laws applicable to each Site.

(f) Each AT&T Lessor shall be afforded access, at reasonable times and upon reasonable prior notice, to all of Tower Operator’s records, books, correspondence, instructions, blueprints, permit files, memoranda and similar data relating to the compliance of the Towers with all applicable Laws, except privileged or confidential documents or where such disclosure is prohibited by Law. Tower Operator shall not dispose of any such information before the earlier of five (5) years after the date on which such materials are created or received by Tower Operator and five (5) years after the expiration or termination of this Agreement as to the subject Site. Any such information described in this Section 24(f) shall be open for inspection upon reasonable notice by such AT&T Lessor, at its cost, and its authorized representatives at reasonable hours at Tower Operator’s principal office.

-61-

(g) If, as to any Site, any material Governmental Approval or certificate, registration, permit, license, easement or approval relating to the operation of such Site is canceled, expires, lapses or is otherwise withdrawn or terminated (except as a result of the acts or omissions of an AT&T Lessor or its Affiliates, agents or employees) or Tower Operator has breached any of its obligations under this Section 24, and Tower Operator has not confirmed to the AT&T Lessors, within forty-eight (48) hours of obtaining notice thereof, that Tower Operator is commencing to remedy such non-compliance or, after commencing to remedy such non-compliance, Tower Operator is not diligently acting to complete the remedy thereof, then the AT&T Lessors shall have the right, in addition to its other remedies pursuant to this Agreement, at law, or in equity, to take appropriate action to remedy any such non-compliance and be reimbursed for its reasonable, out-of-pocket costs from Tower Operator as provided in Section 28. Notwithstanding anything to the contrary contained herein, Tower Operator shall have no obligation to obtain or restate (or otherwise provide information for the AT&T Lessors to obtain or restate) any Governmental Approval, certificates, permits, licenses, easements or approvals that relate exclusively to AT&T Communications Equipment itself. Each AT&T Lessor shall, at all times, keep, operate and maintain AT&T Communications Equipment at each Site in a safe condition, in good repair, in accordance with applicable Laws and with the general standard of care in the telecommunications industry.

(h) The following provisions shall apply with respect to the marking/lighting systems serving the Sites (but only if such marking/lighting systems are required by applicable Law (including as part of or as a condition of any Governmental Approval or as in place as of the Effective Date) or existing written agreements):

(i) In addition to the requirements set out elsewhere in this Section 24 and Section 25, for each Site, Tower Operator agrees to monitor the lighting system serving such Site in accordance with the requirements of applicable Law and file all required Notices To Airmen (“NOTAM”) and other required reports in connection therewith. Tower Operator agrees, as soon as practicable, to repair any failed lighting system and deteriorating markings in accordance with the requirements of applicable Law in all material respects. Tower Operator shall provide the subject AT&T Lessors with a copy of any NOTAM and a monthly report in electronic format describing all pertinent facts relating to the lighting system serving the Sites, including lighting outages, status of repairs, and location of outages.

(ii) In addition to and not in limitation of Section 29, if Tower Operator defaults on its obligations under this Section 24(h), and Tower Operator has not confirmed to the applicable AT&T Lessor, within forty-eight (48) hours of obtaining notice thereof, that Tower Operator is commencing to remedy such default, or, after commencing to remedy such default, Tower Operator is not diligently acting to complete the remedy thereof, such AT&T Lessor, in addition to its other remedies pursuant to this Agreement, at law, or in equity, may elect to take appropriate action to repair or replace any aspect of the marking/lighting system, in which case such AT&T Lessor shall provide Tower Operator with an invoice for related costs on a monthly basis, which amount shall be paid by Tower Operator to such AT&T Lessor, as applicable, within 45 Business Days of Tower Operator’s receipt of such invoice.

-62-

SECTION 25. Compliance with Specific FCC Regulations.

(a) Tower Operator understands and acknowledges that Tower Subtenants are engaged in the business of operating Communications Equipment at each Site. The Communications Equipment is subject to the rules, regulations, decisions and guidance of the FCC, including those regarding exposure by workers and members of the public to the radio frequency emissions generated by AT&T Communications Equipment. Tower Operator 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. To the extent Tower Operator is required to do so under applicable FCC rules, regulations, decisions and guidance, Tower Operator shall use commercially reasonable efforts to install, or require the Tower Subtenants to install, at its or their expense, such marking, signage or barriers to restrict access to any Site as is necessary in order to comply with the applicable FCC rules, regulations, decisions and guidance with respect to Communications Equipment other than AT&T Communications Equipment, and with respect to AT&T Communications Equipment, AT&T Collocator shall install same. Tower Operator further agrees to post, or to require the Tower Subtenants to post, prominent signage as may be required by applicable Law or by the order of any Governmental Authority at all points of entry to each Site regarding the potential RF emissions, with respect to Communications Equipment other than AT&T Communications Equipment, and with respect to AT&T Communications Equipment, AT&T Collocator shall install same. Tower Operator shall cooperate in good faith with AT&T Collocator to minimize any confusion or unnecessary duplication that could result in similar signage being posted with respect to any AT&T Communications Equipment at or near any Site in respect of any AT&T Collocation Space on such Site.

(b) From and after the Effective Date, each AT&T Lessor shall cooperate (and cause its Affiliates to cooperate) with each Tower Subtenant with respect to each Site regarding compliance with applicable FCC rules, regulations, decisions and guidance.

(c) The Parties acknowledge that AT&T Collocator (or an Affiliate thereof) is licensed by the FCC to provide telecommunications and wireless services and that the Sites are used to provide those services. Nothing in this Agreement shall be construed to transfer control of any FCC authorization held by AT&T Collocator (or an Affiliate thereof) to Tower Operator with respect to telecommunications services provided by AT&T Collocator or its Affiliates, to allow Tower Operator to in any manner control the AT&T Communications Equipment, or to limit the right of AT&T Collocator (or an Affiliate thereof) to take all necessary actions to comply with its obligations as an FCC licensee or with any other legal obligations to which it is or may become subject (subject to the other terms of this Agreement with respect to actions AT&T Collocator or its Affiliates may take with respect to a Site).

(d) With respect to any Lease Site or Pre-Lease Site registered with the FCC pursuant to 47 C.F.R. § 17.4, AT&T Guarantor and the AT&T Lessors shall ensure and cause the name of the owner of such Site on the FCC registry be changed to the appropriate AT&T Lessor.

(e) With respect to any Lease Site or Pre-Lease Site registered with the FCC pursuant to 47 C.F.R. § 17.4, promptly after the Effective Date, Tower Operator and the AT&T

-63-

Lessors will reasonably cooperate to cause the name of the owner of such Site on the antenna structure registry to be changed to Tower Operator.

SECTION 26. Holding Over.

If Tower Operator remains in possession of the Included Property of any Site after expiration or termination of the Term as to such Site, then Tower Operator shall be and become a tenant at sufferance, and there shall be no renewal or extension of the Term as to such Site by operation of Law. During any such holdover period with respect to a Site, Tower Operator shall pay monthly rent equal to 150% of all rent and other amounts payable by Tower Subtenants with respect to such Site on a monthly basis, except that such month-to-month tenancy shall be terminable by either Party on thirty (30) days’ notice (subject to the provisions of Section 9). In addition, AT&T Collocator shall not be required to pay Tower Operator the AT&T Rent Amount or any other monthly charge under the MPL Site MLA or this Agreement with respect to the use and occupancy of any Site during the period in which Tower Operator is a holdover tenant.

SECTION 27. Rights of Entry and Inspection.

With advance notice in accordance with and only to the extent required under Section 28, each AT&T Lessor and its representatives, agents and employees, at AT&T Lessor’s sole cost and expense, shall be entitled to enter any Site at all reasonable times (but subject to giving Tower Operator at least one Business Day’s prior notice) for the purposes of inspecting such Site, making any repairs or replacements, performing any maintenance, or performing any work on the Site, to the extent required or expressly permitted by this Agreement; provided that none of the AT&T Lessors or its representatives, agents and employees may make any repairs or replacements or perform any maintenance, inspection or other work on a Tower, Tower Operator Equipment or on any third party’s property. Nothing in this Section 27 shall imply or impose any duty or obligation upon any AT&T Lessor to enter upon any Site at any time for any purpose, or to inspect any Site at any time, or to perform, or pay the cost of, any work that Tower Operator is required to perform under any provision of this Agreement, and no AT&T Lessor has any such duty or obligation. Nothing in this Section 27 shall affect any right of entry or inspection or any other right afforded to AT&T Collocator pursuant to the MPL Site MLA.

SECTION 28. Right to Act for Tower Operator.

In addition to and not in limitation of any other right or remedy AT&T Lessors may have under this Agreement, if Tower Operator fails to make any payment or to take any other action when and as required under this Agreement in order to correct a condition the continued existence of which is imminently likely to cause bodily injury or injury to property or have a material adverse effect on any Site, then subject to the following sentence, the applicable AT&T Lessor or its Affiliate may, without demand upon Tower Operator and without waiving or releasing Tower Operator from any duty, obligation or liability under this Agreement, make any such payment or take any such other action required of Tower Operator, in each case in compliance with applicable Law in all material respects and in a manner consistent with the general standard of care in the tower industry. Unless Tower Operator’s failure results in or relates to an Emergency, the applicable AT&T Lessor shall give Tower Operator at least 10 Business Days’ prior written notice of such AT&T Lessor’s intended action and Tower Operator

-64-

shall have the right to cure such failure within such 10 Business Day period unless the same is not able to be remedied in such 10 Business Day period, in which event such 10 Business Day period shall be extended; provided that Tower Operator has commenced such cure within such 10 Business Day period and continuously prosecutes the performance of the same to completion with due diligence. No prior notice shall be required in the event of an Emergency. The actions that the applicable AT&T Lessor may take include the payment of insurance premiums that Tower Operator is required to pay under this Agreement and the payment of Taxes that Tower Operator is required to pay under this Agreement. Each AT&T Lessor may pay all incidental costs and expenses incurred in exercising its rights under this Section 28, including reasonable attorneys’ fees and expenses, penalties, re-instatement fees, late charges, and interest. An amount equal to 120% of the total amount of the costs and expenses incurred by any AT&T Lessor in accordance with this Section 28 shall be due and payable by Tower Operator upon demand and bear interest at the rate of the lesser of (A) the Prime Rate or (B) 10% per annum from the date five days after demand until paid by Tower Operator.

SECTION 29. Defaults and Remedies.

(a) AT&T Lessor Events of Default. The following events constitute events of default by any AT&T Lessor or any AT&T Ground Lease Party (as applicable):

(i) In respect of this Agreement, any AT&T Lessor or any AT&T Ground Lease Party fails to perform any obligations under any Ground Lease (other than any obligation assumed by Tower Operator) that results in a default or breach of such Ground Lease and, after written notice from Tower Operator, fails to cure the default or breach within the applicable cure period or, if no cure period exists, within 30 days after receiving such notice (provided, however, the foregoing shall not constitute an event of default if such AT&T Lessor or AT&T Ground Lease Party is disputing in good faith the existence of such breach or default, and if the Ground Lessor thereunder does not have a right to terminate the Ground Lease during such dispute);

(ii) Any AT&T Lessor or any AT&T Ground Lease Party violates or breaches any material term of this Agreement in respect of any Site, and such AT&T Lessor or such AT&T Ground Lease Party (as applicable) fails to cure such breach or violation within 30 days of receiving written notice thereof from Tower Operator specifying such breach or violation in reasonable detail, or, if the violation or breach cannot be cured within 30 days (other than a failure to pay money), fails to take steps to cure such violation or breach within such 30 days and act continuously and diligently to complete cure of such violation or breach within a reasonable time thereafter; provided that if any such default causes Tower Operator to be in default under any Collocation Agreement existing prior to the Effective Date, the 30 day period referenced above in this Section 29(a)(ii) shall be reduced to such lesser time period as Tower Operator notifies such AT&T Lessor in writing that Tower Operator has to comply under such Collocation Agreement;

(iii) A Bankruptcy Event occurs with respect to any AT&T Lessor or any AT&T Ground Lease Party, or the lease of any Site to Tower Operator or other right by Tower Operator to use and occupy the Site is rejected under Section 365 of the

-65-

Bankruptcy Code; or

(iv) The occurrence of any event of default by AT&T Collocator under the MPL Site MLA or any Affiliate of AT&T Collocator under any site Lease Agreement related to the MPL Site MLA (which shall be deemed a separate breach hereof and an event of default hereunder).

Notwithstanding anything to the contrary contained herein, no event of default shall be deemed to occur and exist under this Agreement as a result of a violation or breach by any AT&T Lessor of (i) any term of this Agreement that requires such AT&T Lessor to comply in all respects with any applicable Law (including, for the avoidance of doubt, any applicable Environmental Law) or any Ground Lease if (x) such AT&T Lessor complies with such Law or such Ground Lease, as applicable, in all material respects and (y) no claims, demands, assessments, actions, suits, fines, levies or other penalties have been asserted against or imposed on Tower Operator by any Governmental Authority as a result of such AT&T Lessor’s non-compliance in all respects with such Law or by the applicable Ground Lessor as a result of such AT&T Lessor’s non-compliance in all respects with such Ground Lease.

(b) Tower Operator Remedies.

(i) In addition to the remedies, if any, that may be available to Tower Operator under the MPL Site MLA, upon the occurrence of events of default not cured during the applicable time period for curing the same (whether of the same or different types) by any AT&T Lessor, any AT&T Ground Lease Party or any Affiliate thereof under Section 29(a), Tower Operator may deliver to the applicable AT&T Lessor or AT&T Ground Lease Party a second notice of default marked at the top in bold lettering with the following language: “A RESPONSE IS REQUIRED WITHIN 15 BUSINESS DAYS OF RECEIPT OF THIS NOTICE PURSUANT TO THE TERMS OF A MASTER LEASE AGREEMENT WITH THE UNDERSIGNED AND FAILURE TO RESPOND MAY RESULT IN TERMINATION OF YOUR RIGHTS” and the envelope containing the request must be marked “PRIORITY”. If the applicable AT&T Lessor or AT&T Ground Lease Party does not cure the event of default within 15 Business Days after delivery of such second notice, then Tower Operator may terminate this Agreement as to the leaseback or other use and occupancy of the Site only as to those Sites with respect to which such event of default is occurring.

(ii) Notwithstanding anything to the contrary contained herein, if any AT&T Lessor or an AT&T Ground Lease Party is determined pursuant to Section 29(g) to be in default, then such AT&T Lessor or such AT&T Ground Lease Party shall have 20 days following such determination to initiate a cure of such default and so long as such cure is diligently completed, an event of default with respect to such AT&T Lessor or such AT&T Ground Lease Party shall be deemed not to have occurred.

(c) Tower Operator Events of Default. The following events constitute events of default by Tower Operator:

(i) (A) Tower Operator fails to timely pay Ground Rent or otherwise

-66-

fails to perform any obligation assumed by Tower Operator hereunder under any Ground Lease, resulting in a default or breach of such Ground Lease and, after written notice from the AT&T Lessors, fails to cure the breach or default within the applicable cure period or, if no cure period exists, within 30 days after receiving such notice or (B) Tower Operator otherwise fails to make payment of any amount due under this Agreement and such failure continues for more than 15 Business Days after written notice from the AT&T Lessors (provided, however, the foregoing shall not constitute an event of default if Tower Operator is disputing in good faith the existence of such breach or default, or, if applicable, the Ground Lessor thereunder does not have a right to terminate the Ground Lease during such dispute);

(ii) Tower Operator violates or breaches any material term of this Agreement in respect of any Site, and Tower Operator fails to cure such breach or violation within 30 days of receiving written notice thereof from the AT&T Lessors specifying such breach or violation in reasonable detail, or, if the violation or breach cannot be cured within 30 days (other than a failure to pay money), fails to take steps to cure such violation or breach within such 30 days and act diligently to complete the cure of such violation or breach within a reasonable time thereafter;

(iii) A Bankruptcy Event occurs with respect to Tower Operator, or the leaseback to AT&T Collocator or other right by AT&T Collocator to use and occupy the AT&T Collocation Space is rejected by Tower Operator under Section 365 of the Bankruptcy Code; or

(iv) The occurrence of any event of default by Tower Operator under the MPL Site MLA (which shall be deemed a separate breach of and an event of default under this Agreement).

Notwithstanding anything to the contrary contained herein, no event of default shall be deemed to occur and exist under this Agreement as a result of a violation or breach by Tower Operator of (i) any term of this Agreement that requires Tower Operator to comply in all respects with any applicable Law (including, for the avoidance of doubt, any applicable Environmental Law) or any Ground Lease if (x) Tower Operator complies with such Law or such Ground Lease, as applicable, in all material respects and (y) no claims, demands, assessments, actions, suits, fines, levies or other penalties have been asserted against or imposed on any AT&T Lessor by any Governmental Authority as a result of Tower Operator’s non-compliance in all respects with such Law or by the applicable Ground Lessor as a result of Tower Operator’s non-compliance in all respects with such Ground Lease or (ii) Section 4(a), Section 11, Section 19, Section 24 or Section 25 if such violation or breach arises out of or relates to any event, condition or occurrence that occurred prior to, or is in existence as of, the Effective Date unless such violation or breach has not been cured on or prior to the first anniversary of the Effective Date; provided, however, that if any AT&T Lessor gives Tower Operator notice of any event, condition or occurrence giving rise to an obligation of Tower Operator to repair, maintain or modify a Tower under Section 11(a), or Tower Operator otherwise obtains knowledge thereof, Tower Operator shall remedy such event, condition or occurrence in accordance with its standard protocol and procedures for remedying similar events, conditions or occurrences with respect to its portfolio of telecommunications tower sites (taking into account whether such event, condition or

-67-

occurrence is deemed an emergency, a priority or a routine matter in accordance with Tower Operator’s then current practices).

(d) AT&T Lessor Remedies.

(i) Upon the occurrence of any event of default by Tower Operator under Section 29(c)(i), Section 29(c)(ii) or Section 29(c)(iv) (which relates to an event of default by Tower Operator under Section 25(c)(i) of the MPL Site MLA) in respect of any Site, the AT&T Lessors or any applicable AT&T Ground Lease Party may deliver to Tower Operator a second notice of default marked at the top in bold lettering with the following language: “A RESPONSE IS REQUIRED WITHIN 15 BUSINESS DAYS OF RECEIPT OF THIS NOTICE PURSUANT TO THE TERMS OF A MASTER PREPAID LEASE WITH THE UNDERSIGNED AND FAILURE TO RESPOND MAY RESULT IN TERMINATION OF YOUR RIGHTS” and the envelope containing the request must be marked “PRIORITY”. If Tower Operator does not cure the event of default within 15 Business Days after delivery of such second notice, such AT&T Lessor or AT&T Ground Lease Party may terminate this Agreement as to such Site by giving Tower Operator written notice of termination, and this Agreement shall be terminated as to such Site 30 days after Tower Operator’s receipt of such termination notice; provided, however, that this Agreement shall otherwise remain in full force and effect.

(ii) Upon the occurrence of any event of default by Tower Operator under Section 29(c)(iii) or Section 29(c)(iv) (that relates to an event of default by any Tower Operator under Section 25(c)(iii) of the MPL Site MLA), AT&T Lessors may terminate this Agreement as to the lease or other use and occupancy of any Sites by Tower Operator by giving Tower Operator written notice of termination; termination with respect to the affected Site shall be effective 30 days after Tower Operator’s receipt of such termination notice; provided, however, that this Agreement shall otherwise remain in full force and effect.

(iii) Notwithstanding anything to the contrary contained herein, if Tower Operator is determined pursuant to Section 29(g) to be in default, then Tower Operator shall have 20 days following such determination to initiate a cure of such default and so long as such cure is diligently completed, an event of default with respect to Tower Operator shall not be deemed to have occurred.

(e) Force Majeure. In the event that either party shall be delayed, hindered in or prevented from the performance of any act required hereunder by reason of events of Force Majeure, or any delay caused by the acts or omissions of the other party in violation of this Agreement or the MPL Site MLA, then the performance of such act (and any related losses and damages caused the failure of such performance) shall be excused for the period of delay and the period for performance of any such act shall be extended for a period equivalent to the period required to perform as a result of such delay.

(f) No Limitation on Remedies. AT&T Lessors or Tower Operator, as applicable, may pursue any remedy or remedies provided in this Agreement or any remedy or remedies provided for or allowed by law or in equity, separately or concurrently or in any

-68-

combination, including (i) specific performance or other equitable remedies, (ii) money damages arising out of such default or (iii) in the case of Tower Operator’s default, the AT&T Lessors may perform, on behalf of Tower Operator, Tower Operator’s obligations under the terms of this Agreement and seek reimbursement pursuant to Section 28.

(g) Arbitration. Notwithstanding anything in this Agreement to the contrary, any Party receiving notice of a default or termination under this Agreement may, within ten (10) days after receiving the notice, initiate arbitration proceedings to determine the existence of any such default or termination right. These arbitration proceedings shall include and be consolidated with any proceedings initiated after notices delivered at or about the same time under the MPL Site MLA. Such arbitration proceedings shall be conducted in accordance with and subject to the rules and practices of The American Arbitration Association under its Commercial Arbitration Rules from time to time in force. There shall be three (3) arbitrators, selected in accordance with the rules of The American Arbitration Association under its Commercial Arbitration Rules. A decision agreed on by two (2) of the arbitrators shall be the decision of the arbitration panel. Such arbitration panel conducting any arbitration hereunder shall be bound by, and shall not have the power to modify, the provisions of this Agreement. During the pendency of such arbitration proceedings, the notice and cure periods set forth in this Section 29 shall be tolled and the Party alleging the default may not terminate this Agreement on account of such alleged event of default. Nothing in this Section 29(g) is intended to be or to be construed as a waiver of a Party’s right to any remedy set forth elsewhere in this Agreement or that may not be enforced by means of arbitration, including, without limitation, the rights of set off, injunctive relief and specific performance.

(h) Remedies Not Exclusive. Unless expressly provided herein, a Party’s pursuit of any one or more of the remedies provided in this Agreement shall not constitute an election of remedies excluding the election of another remedy or other remedies, a forfeiture or waiver of any amounts payable under this Agreement 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 Agreement.

(i) No Waiver. 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 Agreement, and no custom or practice at variance with the terms of this Agreement, shall constitute a waiver by either Party of the right to demand strict and exact compliance with the terms and conditions of this Agreement. Except as otherwise provided herein, any termination of this Agreement pursuant to this Section 29, or partial termination of a Party’s rights hereunder, shall not terminate or diminish any Party’s rights with respect to the obligations that were to be performed on or before the date of such termination.

-69-

(j) Notice Parties. Notices of default or termination delivered pursuant to this Section 29 shall not be effective unless delivered to each of the Persons required by Section 37(e) pursuant to the terms thereof.

SECTION 30. Quiet Enjoyment.

Each AT&T Lessor covenants that Tower Operator shall, subject to the terms and conditions of this Agreement, peaceably and quietly hold and enjoy the Included Property of each Lease Site and shall have the right provided herein to operate each Managed Site during the Term thereof without hindrance or interruption from such AT&T Lessor, any Party comprising AT&T or any other AT&T Group Member.

SECTION 31. No Merger.

There shall be no merger of this Agreement or any subleasehold interest or estate created by this Agreement in any Site with any superior estate held by a Party by reason of the fact that the same Person may acquire, own or hold, directly or indirectly, both the subleasehold interest or estate created by this Agreement in any Site and such superior estate; and this Agreement shall not be terminated, in whole or as to any Site, except as expressly provided in this Agreement. Without limiting the generality of the foregoing provisions of this Section 31, there shall be no merger of the subleasehold interest or estate created by this Agreement in Tower Operator in any Site with any underlying fee interest that Tower Operator may acquire in any Site that is superior or prior to such subleasehold interest or estate created by this Agreement in Tower Operator.

SECTION 32. Broker and Commission.

(a) All negotiations in connection with this Agreement have been conducted by and between AT&T Lessors and Tower Operator and their respective Affiliates without the intervention of any Person or other party as agent or broker other than TAP Advisors and X.X. Xxxxxx Securities LLC (the “Financial Advisors”), which are advising AT&T Parent in connection with this Agreement and related transactions and which shall be paid solely by AT&T Parent.

(b) Each of Tower Operator and each AT&T Lessor warrants and represents to the other that there are no broker’s commissions or fees payable by it in connection with this Agreement by reason of its respective dealings, negotiations or communications other than the advisor’s fees payable to the Financial Advisors which shall be payable by AT&T Parent. Each of Tower Operator and each AT&T Lessor agrees to indemnify and hold harmless the other from any and all damage, loss, liability, expense and claim (including but not limited to attorneys’ fees and court costs) arising with respect to any such commission or fee which may be suffered by the indemnified Party by reason of any action or agreement of the indemnifying Party.

SECTION 33. Recording of Memorandum of Site Lease Agreement; Bifurcation of Site.

(a) Subject to the applicable provisions of the Master Agreement, for each Lease Site, following the execution of this Agreement or after any Subsequent Closing, each

-70-

AT&T Lessor and Tower Operator shall each have the right, at its sole cost and expense, to cause a Memorandum of Site Lease Agreement to be filed in the appropriate county or other local property records (unless the Ground Lease for any applicable Lease Site prohibits such recording) to provide constructive notice to third parties of the existence of this Agreement and shall promptly thereafter provide or cause to be provided in electronic form a recorded copy of same to the other Party.

(b) In addition to and not in limitation of any other provision of this Agreement, the Parties shall have the right to review and make corrections, if necessary, to any and all exhibits to this Agreement or to the applicable Memorandum of Site Lease Agreement. After making such corrections, the Party that recorded the Memorandum of Site Lease Agreement shall re-record such Memorandum of Site Lease Agreement to reflect such corrections, at the sole cost and expense of the Party that requested such correction, and shall promptly provide in electronic form a recorded copy of same to the other Party.

(c) With respect to any Site containing Reserved Property, upon request of either Party, the Parties will reasonably cooperate to bifurcate, and use commercially reasonable efforts to cause the applicable Ground Lessor to bifurcate, the fee or ground leasehold interest in the Site to legally separate the Reserved Property belonging to an AT&T Group Member from the Included Property belonging to Tower Operator, at the cost and expense of such AT&T Group Member.

SECTION 34. Tax Indemnities.

(a) Income Tax Indemnity.

(i) Tax Assumptions. In entering into this Agreement and related documents, the AT&T Group has made the following assumptions regarding the characterization of the transactions contemplated under this Agreement for federal income Tax purposes (the “Tax Assumptions”):

(A) For federal income Tax purposes, this Agreement shall be treated as a “true lease” with respect to all of the Included Property, the members of the AT&T Group shall 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 Included Property, and Tower Operator shall be treated (or, if Tower Operator is a disregarded entity for federal income Tax purposes, the entity treated as the owner of Tower Operator for federal income Tax purposes) as the lessee of the Included Property;

(B) Following the execution of this Agreement, the AT&T Group shall be entitled to deduct, pursuant to Section 168(b) of the Code, depreciation deductions with respect to the AT&T Group’s adjusted Tax basis in the Included Property using the same depreciation method(s) as in effect immediately before the execution of this Agreement (“Federal Depreciation Deductions”);

(C) Prepaid Rent and Pre-Lease Rent with respect to each Site

-71-

shall be paid under a single lease subject to Section 467 of the Code and shall be characterized in part as a loan under Section 467 of the Code and Treasury Regulations issued under such section and the AT&T Group shall be entitled to deduct interest attributable thereto with respect to each Site as set forth in Exhibit D; and

(D) The only amounts that any AT&T Group Member shall be required to include in gross income with respect to the transactions contemplated by this Agreement and related documents shall be (1) Rent and Pre-Lease Rent as it accrues as rent in accordance with the terms of this Agreement and the application of Section 467 of the Code and Treasury Regulations issued under such section and as set forth in Exhibit D with respect to each Site; (2) any indemnity (including any gross up) pursuant to this Agreement; (3) any amounts paid or otherwise recognized pursuant to a voluntary sale or other disposition by any AT&T Group Member (other than a sale or disposition attributable to a default by Tower Operator or the exercise of remedies by any AT&T Lessor or its Affiliate under this Agreement) of any Included Property, it being understood for these purposes that a sale or disposition that may be deemed to have occurred on the Effective Date is not a sale; (4) proceeds upon Tower Operator’s exercise of the Purchase Option pursuant to Section 20; (5) any costs and expenses of any AT&T Lessor or its Affiliate (and any interest thereon) paid or reimbursed by Tower Operator pursuant to this Agreement; (6) income attributable to the reversion of Modifications made by Tower Operator to any AT&T Lessor at the end of the Term; (7) amounts expressly identified as interest in the Agreement and payable to any AT&T Lessor or any AT&T Group Member; and (8) any other amount to the extent such item of income results in an equal and offsetting deduction in the same taxable year.

(ii) Tower Operator’s Representations and Covenants. Tower Operator hereby represents and covenants to each AT&T Group Member as follows:

(A) Tower Operator, any Affiliate of Tower Operator, any assignee or sublessee of Tower Operator and any user (other than any AT&T Lessor or its Affiliates) of any portion of the Included Property shall not claim depreciation deductions as the owner of any of the Included Property for federal income Tax purposes during the Term (and thereafter unless Tower Operator purchases such property pursuant to Section 20), with respect to such Included Property or portion of such Included Property, except with respect to Modifications financed by Tower Operator or such assignee, sublessee, or other user, nor shall they take any other action in connection with filing a Tax return, make any public statement or otherwise undertake any action which would be inconsistent with (i) the treatment of the AT&T Group Members as the direct or indirect owners and lessors of the Included Property for federal income Tax purposes, (ii) the Tax Assumptions or (iii) Section 10 and Exhibit D.

(B) None of the Included Property shall constitute “tax-exempt use property” as defined in Section 168(h) of the Code other than solely as a

-72-

result of use by any AT&T Lessor or their Affiliates and any other Person that is a Tower Subtenant as of the date of the Master Agreement;

(C) On the Effective Date, no Modifications to any of the Included Property shall be required in order to render any of the Included Property complete for its intended use by Tower Operator except for ancillary Severable Modifications that are customarily selected and furnished by lessees of property similar in nature to the Included Property;

(D) Tower Operator has no current plan or intention of making any Modification or repair with respect to any of the Included Property that would not be treated as severable improvements or permitted non-severable improvements within the meaning of Rev. Proc. 2001-28, 2001-1 C.B. 1156;

(E) Tower Operator has no current plan or intention of making any Modification or repair with respect to any of the Included Property the value of which as of the end of the Term with respect to such Included Property would compel Tower Operator to exercise any of the Purchase Options under Section 20; and

(F) Tower Operator is not legally obligated or economically compelled to exercise any of the Purchase Options provided in Section 20 and Tower Operator has not decided whether it shall exercise any of the Purchase Options provided in Section 20, and it has no plans to enter into or incur such obligation or to make such decision in the immediate future.

(iii) Indemnity for Tax Losses.

(A) If, as a result of:

(1) the inaccuracy of any representation of Tower Operator, or the breach of any covenant of Tower Operator, set forth in the Transaction Documents;

(2) the failure by Tower Operator to perform any act required of it under any of the Transaction Documents;

(3) any disposition of Included Property in connection with a default by Tower Operator or the exercise of remedies under this Agreement; or

(4) a Bankruptcy Event of Tower Operator or any Affiliate thereof;

any AT&T Group Member (each a “Tax Indemnitee”) shall not claim on the relevant income Tax return based upon a written opinion from independent tax counsel reasonably acceptable to Tower Operator (setting forth in reasonable detail the facts and analysis upon which such opinion is based) that there is not substantial authority (within the meaning of Treasury Regulation

-73-

§1.6662-4(d)(2) as in effect from time to time) 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 Event”), then, in any taxable year in which a Tax Indemnitee suffers a Tax Loss as a result of the Tax Event, Tower Operator shall pay to such Tax Indemnitee, at the time specified below, as an indemnity the amount of the Tax Loss for such taxable year. Subject to other adjustments required by this Section 34(a)(iii)(A), the “Tax Loss” for a taxable year shall equal the sum of (i) the excess of the actual additional federal and state income Taxes payable by the Tax Indemnitee (or its consolidated or affiliated group as applicable) for the taxable year, taking into account the Tax Event, over such Taxes that would have been payable in the absence of the Tax Event, (ii) any interest, penalties and additions to Tax actually payable by the Tax Indemnitee as a result of the Tax Event, and (iii) an additional gross-up amount so that the Tax Indemnitee is made whole on an after-Tax basis for its liabilities described in clause (i) and (ii), taking into account the income Taxes it actually pays on the payments it receives under this sentence, including those under this clause (iii). Tower Operator shall not be required to make any payment under this Section 34(a)(iii)(A) earlier than, (a) in the case of a Tax Loss that is not being contested pursuant to Section 34(d), 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, (b) in the case of a Tax Loss that is being contested pursuant to Section 34(d), 30 days after the date on which a Final Determination is made (or as otherwise provided in Section 34(d)) and (c) 20 days after the receipt by Tower Operator 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”). For the avoidance of doubt, a Tax Event may give rise to a Tax Loss in a future taxable year (e.g., if the Tax Indemnitee has a net operating loss in the year of the Tax Event and the loss could have been carried forward and used against unrelated income in the future year had it not been absorbed in the year of the Tax Event as a result of the Tax Event). If a Tax Indemnitee claims a Tax Loss in a particular taxable year on a Tax Indemnity Notice and Tower Operator indemnifies the Tax Indemnitee accordingly, and it is later determined that the Tax Indemnitee did not have a Tax Loss, or had a smaller Tax Loss, in such taxable year (e.g., as a result of an audit adjustment or a net operating loss carryback to such taxable year), the Tax Indemnitee shall reimburse Tower Operator so as to put the parties in the position they would have been in on the basis of the actual Tax Loss.

(B) Verification of Calculations. Tower Operator may timely request that any Tax Indemnity Notice be verified by a nationally recognized independent accounting firm or a lease advisory firm selected by Tower Operator and reasonably acceptable to such Tax Indemnitee. Such verification shall be at Tower Operator’s expense unless such accounting firm determines that the amount payable by Tower Operator is more than five 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 Tower Operator or any other

-74-

person) all information reasonably necessary for such verification.

(iv) Exceptions. Notwithstanding any provision of this Section 34(a) to the contrary (other than with respect to the loss of Tax Savings for which an AT&T Group Member has reimbursed or credited Tower Operator under Section 34(c), in which case only the exceptions listed in clauses (C), (F) and (G) shall apply), Tower Operator 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:

(A) Other than as a result of an event or circumstance described in Section 34(a)(iii), the determination that this Agreement is not a “true lease” for federal income Tax purposes or that the members of the AT&T Group, directly or indirectly through one or more entities that are classified as partnerships or disregarded entities for federal income tax purposes, are not the owners or sublessors of the Included Property, or that Section 467 of the Code does not apply to this Agreement in accordance with its terms;

(B) The voluntary sale, assignment, transfer or other disposition or the involuntary sale, assignment, transfer or other disposition attributable to a Bankruptcy Event 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 or any of its Affiliates, in either case, of any of the Included Property or portion of such Included Property by any such Tax Indemnitee or any of its Affiliates other than a sale, assignment, transfer or disposition (1) contemplated by the Transaction Documents or to or at the request of Tower Operator; (2) otherwise resulting from the exercise by any AT&T Group Member of its rights or performance of its obligations under the Transaction Documents; or (3) in connection with a default by Tower Operator or exercise of remedies under this Agreement;

(C) The gross negligence or willful misconduct of such Tax Indemnitee;

(D) Penalties, interest or additions to Tax to the extent based upon issues unrelated to the transactions contemplated by this Agreement and related documents;

(E) Tower Operator’s exercise of the Purchase Option provided in Section 20;

(F) The failure by the AT&T Group or any AT&T Group Member timely or properly to claim any Federal Income Tax Benefits or to exclude income on the appropriate Tax return other than in accordance with Section 34(a)(iii);

(G) Any failure of the Tax Indemnitee to have taken all the actions, if any, required of it by Section 34(d) to contest the Loss and such failure

-75-

materially prejudices the ability to contest, and Tower Operator had a reasonable basis for such contest;

(H) Any change in the Code enacted, adopted or promulgated on or after the date of the Master Agreement; provided that this exclusion shall not apply to any substitution or replacement of any Included Property after a change in Law;

(I) The failure of the AT&T Group, or any single AT&T Group Member, to have sufficient income or Tax liability to benefit from the Federal Income Tax Benefits (it being understood that except as provided herein, this exclusion shall not affect the amount of any indemnity to which an Indemnitee would otherwise be entitled);

(J) The inclusion of income by an AT&T Group Member as a result of the reversion of Modifications made by Tower Operator to any AT&T Lessor at the end of the Term;

(K) Other than as a result of an event or circumstance described in Section 34(a)(iii), a determination that AT&T is not holding the Included Property in the ordinary course of a trade or business or that AT&T did not enter into the transactions contemplated by the Transaction Documents for profit;

(L) The existence of, or any consequence of, the prepayment of the Rent, or the application of Section 467 of the Code or the Treasury regulations promulgated thereunder; provided that the Tower Operator makes all payments when due and accrues all rental expense in accordance with the Proportional Rent as set forth in Exhibit D and provided, further, that this exclusion shall not apply to the entry into a New Lease under Section 21 following the default or breach by Tower Operator;

(M) Any Tax election or Tax Position by an AT&T Group Member that is inconsistent with the Tax Assumptions to the extent of a resulting increase in the Tower Operator’s indemnity obligations hereunder;

(N) A Tax Loss with respect to any period occurring (1) before the Term with respect to a Site, (2) after (and not simultaneously with) the expiration or earlier termination of the Term with respect to a Site or (3) after (and not simultaneously with) the return to AT&T of the Included Property related to a Site, in each case other than interest, fines, penalties and additions to Tax resulting from a Tax Loss that would not be excluded under this clause (N); and

(O) The breach or inaccuracy of any representation, warranty or covenant by any AT&T Group Member in any of the Transaction Documents (except to the extent such breach or inaccuracy is attributed to a breach or inaccuracy of any representation, warranty or covenant of Tower Operator or an Affiliate under the Transaction Documents).

-76-

(b) General Tax Indemnity.

(i) Tower Operator agrees to pay and to indemnify, protect, defend, save, and keep harmless each AT&T Group Member on an after-Tax basis, from and against any and all Taxes for which Tower Operator is responsible under Section 22.

(ii) Exclusions from General Tax Indemnity. The provisions of Section 22 and Section 34(b)(i) shall not apply to, and Tower Operator shall have no responsibility under Section 22 and no liability under Section 34(b)(i) with respect to:

(A) Taxes on any AT&T Group Member 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 (in each case, other than Taxes that are or are in the nature of or in lieu of, sales, use, rental, property, stamp, document filing, license or ad valorem Taxes);

(B) Taxes imposed by any jurisdiction on any AT&T Group Member solely as a result of its activities in such jurisdiction unrelated to the transactions contemplated by this Agreement and related documents;

(C) Taxes on any AT&T Group Member that would not have been imposed but for the willful misconduct or gross negligence of any such member or an Affiliate of any AT&T Group Member or the inaccuracy or breach of any representation, warranty, or covenant of such Tax Indemnitee or any of its Affiliates 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 Tower Operator or an Affiliate under the Transaction Documents);

(D) Taxes that are attributable to any period or circumstance occurring before the Term with respect to a Site or after the expiration or earlier termination of such Term, except to the extent attributable to (1) a failure of Tower Operator or any of its transferees or sublessees or users of the Included Property (other than the AT&T Lessors or their Affiliates) to fully discharge its obligations under this Agreement and related documents, (2) Taxes imposed on or with respect to any payments that are due after the expiration or earlier termination of the Term with respect to a Site and that are attributable to a period or circumstance occurring during such Term or (3) the entry into a New Lease under Section 21 following the default or breach by Tower Operator;

(E) Any Tax that is being contested in accordance with the provisions of Section 34(d) during the pendency of such contest, but only for so long as such contest is continuing in accordance with Section 34(d) and payment is not otherwise required pursuant to Section 34(d);

(F) Taxes imposed on a Tax Indemnitee that would not have

-77-

been imposed but for any act of such Tax Indemnitee (or any Affiliate thereof) that is expressly prohibited, or omission of an act that is expressly required, as the case may be, by any Transaction Document;

(G) Taxes that would not have been imposed but for any voluntary sale, assignment, transfer, pledge or other disposition or hypothecation or the involuntary sale, assignment, transfer or other disposition attributable to a Bankruptcy Event 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 Included Property or portion of such Included Property by any such Tax Indemnitee other than a sale, assignment, transfer, or disposition (1) contemplated by the Transaction Documents or to or at the request of Tower Operator, (2) otherwise resulting from the exercise by any AT&T Group Member of its rights or performance of its obligations under the Transaction Documents or (3) in connection with a default by Tower Operator or exercise of remedies under this Agreement;

(H) Taxes imposed on a Tax Indemnitee that would not have been imposed but for such Tax Indemnitee’s (or Affiliate’s) breach of its contest obligations under Section 34(d) (but only to the extent such breach materially prejudices the Tower Operator’s ability to contest such Taxes or results in an increase in the amount of Tower Operator’s indemnification obligation hereunder);

(I) Taxes imposed on a Tax Indemnitee in the nature of interest, penalties, fines and additions to Tax to the extent based upon issues unrelated to the transactions contemplated by the Transaction Documents;

(J) Taxes imposed on any AT&T Group Member that are United States federal, state or local net income Taxes of any such member;

(K) Taxes imposed in connection with or as a result of the leasing or use of the AT&T Collocation Space by AT&T or its Affiliates or the payment or accrual of the AT&T Rent Amount; or

(L) Taxes to the extent that they are not the responsibility of Tower Operator as described in Section 20(e) or Section 22 without regard to this subsection.

The provisions of this Section 34(b)(ii) shall not apply to any Taxes imposed in respect of the receipt or accrual of any indemnity payment made by Tower Operator on an after-Tax basis and, for purposes of the last sentence of Section 34(c), shall apply only with respect to the exclusions in clauses (C), (F) and (H).

(iii) Reports. If any report, return, certification or statement is required to be filed with respect to any Tax that is the responsibility of Tower Operator under Section 22 or is subject to indemnification under this Section 34(b), Tower Operator shall timely prepare and file the same to the fullest extent permitted by applicable Law (except

-78-

for (A) any report, return or statement relating to any net income Taxes or, (B) any report, return or statement relating to any other Taxes not subject to indemnity under Section 34(b)(ii) or any Taxes in lieu of or enacted in substitution for any of the foregoing, except that, in such cases, Tower Operator shall timely provide appropriate information necessary to file such report, return or statement, (C) any report, return or statement relating to Property Taxes or (D) any other report, return, certification or statement that any AT&T Group Member has notified Tower Operator that such member intends to prepare and file); provided, however, that any AT&T Group Member shall have furnished Tower Operator, at Tower Operator’s expense, with such information reasonably necessary to prepare and file such returns as is within such member’s control. Tower Operator 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, Tower Operator shall, to the fullest extent permitted by applicable Law, cause all xxxxxxxx of such Taxes to be made to each AT&T Group Member in care of Tower Operator, make such payment and furnish written evidence of such payment. Each Party shall furnish promptly upon written request such data, records and documents as the other Party may reasonably require of such Party to enable the other Party to comply with requirements of any taxing authority arising out of such other Party’s participation in the transactions contemplated by this Agreement and related documents.

(iv) Payments. Any Tax for which Tower Operator is responsible under Section 22 or any Tax indemnified under this Section 34(b) shall be paid by Tower Operator directly when due to the applicable taxing authority if direct payment is permitted, or shall be reimbursed to the appropriate AT&T Group Member on demand if paid by such member in accordance herewith. Property Taxes shall be paid in accordance with Section 22(c). Except as explicitly provided in Section 22 or as otherwise provided in this Section 34(b), all amounts payable to an AT&T Group Member under Section 22 or this Section 34 shall be paid promptly in immediately available funds, but in no event later than the later of (i) 10 Business Days after the date of such demand or (ii) 2 Business Days before the date the Tax to which such amount payable relates is due or is to be paid, provided that such amount shall only be payable after the applicable AT&T Group Member provides Tower Operator with a written statement describing in reasonable detail the Tax and the computation of the amount payable. Such written statement shall, at Tower Operator’s request, as long as payment is not delayed, be verified by a nationally recognized independent accounting firm selected by Tower Operator. Such verification shall be at Tower Operator’s expense unless the accounting firm determines that the amount payable by Tower Operator is more than five percent less than the amount shown on such written statement, in which event, the applicable AT&T Group Member shall pay such costs. In the case of a Tax subject to indemnification under this Section 34(b) which is properly subject to a contest in accordance with Section 34(d), Tower Operator (i) shall be obligated to make any advances with respect to such Tax whenever required under Section 34(d) and (ii) shall pay such Tax (in the amount finally determined to be owing in such contest) on an after-Tax

-79-

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, or any Tax Event or other event giving rise to such payment, to or for the account of any Tax Indemnitee by Tower Operator pursuant to Section 34(a) or Section 34(b) of this Agreement (a “Triggering Event”), such Tax Indemnitee realizes a Tax Savings in any taxable year which was not taken into account previously in computing such payment by Tower Operator to or for the account of the Tax Indemnitee, then the Tax Indemnitee shall promptly pay to Tower Operator an amount equal to such Tax Savings. The “Tax Savings” in a taxable year shall be (i) the actual federal and state income Taxes that would have been payable by the Tax Indemnitee (or its consolidated or affiliated group as applicable) for the taxable year in the absence of the Triggering Event, over such Taxes that are actually payable for such taxable year taking such Triggering Event into account, (ii) any interest actually received by the Tax Indemnitee as a result of a refund of tax relating to a Triggering Event, and (iii) an additional gross-up amount to reflect the amount of any additional reduction in Taxes of the Tax Indemnitee attributable to payments made by the Tax Indemnitee pursuant to this sentence, including this clause (iii). However, the Tax Indemnitee shall not be obligated to make such payment to the extent that the amount of such payment would exceed the excess of (x) all prior related indemnity payments (excluding costs and expenses incurred with respect to contests) made by Tower Operator over (y) the amount of all prior related indemnity payments by the Tax Indemnitee to Tower Operator; provided, that any such excess Tax Savings realized (or deemed realized) by such Tax Indemnitee which are not paid to Tower Operator as a result of this sentence shall be carried forward and reduce Tower Operator’s obligations to make subsequent related indemnity payments to such Tax Indemnitee pursuant to this Section 34. For the avoidance of doubt, a Triggering Event may give rise to a Tax Savings in a past or future taxable year (e.g., if the Triggering Event caused or increased a net operating loss in the year of the Triggering Event and such loss is carried back or forwards and results in a reduction in Tax liability in a different taxable year). If a Tax Indemnitee pays or credits Tower Operator in respect of a Tax Savings in a particular taxable year, and it is later determined that the Tax Indemnitee did not have a Tax Savings, or had a smaller Tax Savings, in such taxable year (e.g., as a result of an audit adjustment or a net operating loss carryback to such taxable year), such lost or otherwise unavailable Tax Savings shall be treated as a Tax for which Tower Operator must indemnify the Tax Indemnitee pursuant to Section 34(a) or Section 34(b), as the case may be.

(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 or a Tax against which Tower Operator may be required to indemnify pursuant to Section 34(a) or Section 34(b) (a “Tax Claim”), such Tax Indemnitee shall promptly notify Tower Operator of the claim and provide Tower Operator with information relevant to such claim; provided that the failure by the Tax Indemnitee to provide any such information shall not be treated as a failure to comply with this Section 34(d) except to the extent that the failure prejudices the conduct of such contest. With respect to Taxes indemnified under Section 34(b), Tower Operator shall control the contest at Tower Operator’s expense. With respect to Taxes indemnified under Section 34(a), the Tax Indemnitee shall control the contest at Tower Operator’s expense but shall consult with Tower Operator in good faith, but Tower Operator may require the Tax Indemnitee to contest such Tax Claim unless the Tax Indemnitee has

-80-

waived its right to indemnification for the Tax payment that is being contested. The Tax Indemnitee is not obligated to contest any Tax Claim that requires payment of the Tax as a condition to pursuing the contest unless Tower Operator has loaned, 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 has fully indemnified 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 that the Tower Operator has the right to contest under this Agreement without the prior written consent of Tower Operator unless the Tax Indemnitee has waived its right to indemnification for the Tax payment that is being contested. 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 unless (i) Tower Operator shall have furnished to the Tax Indemnitee an opinion of a nationally recognized, independent tax counsel chosen by Tower Operator and reasonably acceptable to the Tax Indemnitee, to the effect that there is substantial authority for the position to be asserted in appealing the matter in question, (ii) Tower Operator is paying the reasonable costs of such appeal and (iii) the Tax Indemnitee is otherwise required by this Section 34(d) to contest the Taxes at issue hereunder. AT&T Collocator shall cause its Affiliates to comply with their obligations under this Section 34(d).

(e) Tax Records. AT&T Lessors, AT&T and Tower Operator agree to furnish or cause to be furnished to each other, upon request, as promptly as practicable, such information and assistance relating to the Sites (including access to books and records) as is reasonably necessary for Tax purposes. AT&T Lessors, AT&T and Tower Operator shall retain all books and records with respect to Taxes indemnifiable under Section 34(a) or Section 34(b) or payable under Section 22 pertaining to the Sites for a period of at least seven years following the close of the taxable year to which the information relates, or 60 days after the expiration of any applicable statute of limitations, whichever is later. At the end of such period, each Party shall provide the other with at least 60 days’ prior written notice before destroying any such books and records, during which period the Party receiving such notice can elect to take possession, at its own expense, of any books and records reasonably required by such Party for Tax purposes. AT&T Lessors, AT&T and Tower Operator shall cooperate with each other in the conduct of any audit or other proceeding relating to Taxes involving the Sites.

(f) Netting of Losses; Tax Treatment. All payments made pursuant to this Section 34 shall, to the fullest extent permitted by applicable Law, be treated for all Tax purposes (to the extent such treatment is consistent with the rent allocations made for purposes of Section 467 of the Code pursuant to Section 10 of this Agreement) as adjustments to the Rent and Pre-Lease Rent. The amount of any claim under this Section 34 shall take into account any amounts actually recovered by the indemnitee pursuant to any indemnification by, or indemnification agreement with, any Ground Lessor.

(g) Post Purchase Option. In the event that Tower Operator acquires any AT&T Lessor’s or any AT&T Ground Lease Party’s interest in any Site after the exercise of any Purchase Option under Section 20 of this Agreement, Tower Operator shall be liable for all Taxes with respect to such Site with respect to all periods after the exercise of the Purchase Option with respect to such Site (the “Post-Exercise Period”). Tower Operator agrees to pay and to indemnify, protect, defend, save and keep harmless each AT&T Group Member from and

-81-

against any and all Taxes payable with respect to such Site with respect to the Post-Exercise Period; provided, however, that (i) the contest provisions set forth in Section 34(d) shall apply to indemnified Taxes with respect to such Site and (ii) Tower Operator shall not be required to indemnify for any gross-up for Taxes payable by any AT&T Group Member on any payments received under this paragraph. If a Tax for which Tower Operator is responsible under this Section 34(g) (for which Tower Operator was not responsible prior to the Post-Exercise Period) is not calculated or assessed on the basis of a time period, such Tax shall be prorated using a fair and equitable proration method that considers, among other things, the basis upon which such Taxes are assessed. Nothing in this Section 34(g) shall affect any liability for Taxes with respect to any Site prior to the exercise of a Purchase Option with respect to such Site or any liability for Taxes that any AT&T Group Member has under the MPL Site MLA.

(h) Survival. The agreements and indemnities contained in this Section 34 shall survive the termination of this Agreement with respect to any Site.

SECTION 35. Damage to the Site, Tower or the Improvements.

(a) If there occurs a casualty that damages or destroys all or a Substantial Portion of any Site, then within 60 days after the date of the casualty, Tower Operator shall notify the applicable AT&T Lessor or AT&T Ground Lease Party in writing as to whether, in Tower Operator’s reasonable judgment, the Site is a Non-Restorable Site, which notice shall specify in detail the reasons for such determination by Tower Operator, and if such Site is not a Non-Restorable Site (a “Restorable Site”) the estimated time, in Tower Operator’s reasonable judgment, required for Restoration of the Site (a “Casualty Notice”). If Tower Operator fails to give Casualty Notice to the applicable AT&T Lessor or AT&T Ground Lease Party within such 60-day period, the affected Site shall be deemed to be a Restorable Site. If the applicable AT&T Lessor or AT&T Ground Lease Party disagrees with any determination of Tower Operator in the Casualty Notice that the Site is a Non-Restorable Site, such Party may institute arbitration proceedings to determine any such matter in the manner described in Section 29(g). If such Site is a Non-Restorable Site, then either Tower Operator or the applicable AT&T Lessor or AT&T Ground Lease Party, as applicable, shall have the right to terminate this Agreement with respect to such Site by written notice to the other Party (given within the time period required below), whereupon the Term as to such Site shall automatically expire as of the date of such notice of termination. Any such notice of termination shall be given not later than 30 days after receipt of the Casualty Notice (or after final determination that the Site is a Non-Restorable Site if arbitration is instituted as provided above). In all instances Tower Operator shall have the sole right to retain all insurance Proceeds related to a Non-Restorable Site.

(b) If there occurs, as to any Site, a casualty that damages or destroys (i) all or a Substantial Portion of such Site and the Site is a Restorable Site, or (ii) less than a Substantial Portion of any Site, then Tower Operator, at its sole cost and expense, shall promptly commence and diligently prosecute to completion, within a period of 60 days after the date of the damage, the adjustment of Tower Operator’s insurance Claims with respect to such event and, thereafter, promptly commence, and diligently prosecute to completion, the Restoration of the Site. The Restoration shall be carried on and completed in accordance with the provisions and conditions of this Section 35.

-82-

(c) If Tower Operator is required to restore any Site in accordance with Section 35(b), all Proceeds of Tower Operator’s insurance Claims with respect to the related casualty shall be held by Tower Operator or Tower Operator Lender and 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 Tower Operator’s insurance applicable to a particular Site remaining after final payment has been made for work performed on such Site may be retained by and shall be the property of Tower Operator. If the cost of Restoration exceeds the Proceeds of Tower Operator’s insurance, Tower Operator shall pay the excess cost.

(d) Without limiting Tower Operator’s obligations under this Agreement in respect of a Site subject to a casualty, the AT&T Collocator’s rights and obligations in respect of a Site subject to a casualty are as set forth in the MPL Site MLA.

(e) The Parties acknowledge and agree that this Section 35 is in lieu of and supersedes any statutory requirements under the laws of any State applicable to the matters set forth in this Section 35.

SECTION 36. 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 Tower Operator or AT&T Lessors shall have the right to terminate this Agreement as to such Site by providing written notice to the other within 30 days of the occurrence of such Taking, whereupon the Term shall automatically expire as to such Site, as of the earlier of (i) the date upon which title to such Site, or any portion of such Site, is vested in the condemning authority, or (ii) the date upon which possession of such Site or portion of such Site is taken by the condemning authority, as if such date were the Site Expiration Date as to such Site, and each Party shall be entitled to prosecute, claim and retain the entire Award attributable to its respective interest in such Site under this Agreement.

(b) If there occurs a Taking of less than a Substantial Portion of any Site, then this Agreement and all duties and obligations of Tower Operator under this Agreement in respect of such Site shall remain unmodified, unaffected and in full force and effect. Tower Operator shall promptly proceed with the Restoration of the remaining portion of such Site (to the extent commercially feasible) to a condition substantially equivalent to its condition prior to the Taking. Tower Operator shall be entitled to apply the Award received by Tower Operator to the Restoration of any Site from time to time as such work progresses. If the cost of the Restoration exceeds the Award recovered by Tower Operator, Tower Operator shall pay the excess cost. If the Award exceeds the cost of the Restoration, the excess shall be paid to Tower Operator upon completion of the Restoration.

(c) If there occurs a Taking of any portion of any Site for temporary use, then this Agreement shall remain in full force and effect as to such Site. Notwithstanding anything to the contrary contained in this Agreement, during such time as Tower Operator will be out of possession of such Site, if a Lease Site, or unable to operate such Site, if a Managed Site, by reason of such Taking, the failure to keep, observe, perform, satisfy and comply with those terms and conditions of this Agreement, compliance with which are effectively impractical or impossible as a result of Tower Operator’s being out of possession of or unable to operate (as

-83-

applicable), such Site shall not be a breach of or an event of default under this Agreement. Each Party shall be entitled to prosecute, claim and retain the Award attributable to its respective interest in such Site under this Agreement for any such temporary Taking.

SECTION 37. General Provisions.

(a) Counterparts. This Agreement may be executed in any number of counterparts, each such counterpart being deemed to be an original instrument, and all such counterparts shall together constitute the same agreement.

(b) Governing Law; Submission to Jurisdiction; Selection of Forum; Waiver of Trial by Jury. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS THEREOF) AS TO ALL MATTERS, INCLUDING MATTERS OF VALIDITY, CONSTRUCTION, EFFECT, PERFORMANCE AND REMEDIES; provided, however, that the enforcement of this Agreement with respect to a particular Site as to matters relating to real property and matters mandatorily governed by local Law, shall be governed by and construed in accordance with the laws of the state in which the Site in question is located. Each Party agrees that it shall bring any action or proceeding in respect of any claim arising out of or related to this Agreement or the transactions contained in or contemplated by this Agreement, exclusively in the United States District Court for the Southern District of New York or any New York State court sitting in the Borough of Manhattan, City of New York and appellate courts having jurisdiction of appeals from any of the foregoing (the “Chosen Courts”), and solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement, (a) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (b) waives any objection to laying venue in any such action or proceeding in the Chosen Courts, (c) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any Party hereto and (d) agrees that service of process upon such Party in any such action or proceeding shall be effective if notice is given in accordance with Section 37(e) of this Agreement. Each Party hereto irrevocably waives any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

(c) Entire Agreement. This Agreement (including any exhibits hereto) constitutes the entire agreement among the Parties with respect to the subject matter of this Agreement, and supersedes all other prior agreements, understandings, representations and warranties both written and oral, among the Parties, with respect to the subject matter hereof.

(d) Fees and Expenses. Except as otherwise expressly set forth in this Agreement, whether the transactions contemplated by this Agreement are or are not consummated, all legal and other costs and expenses incurred in connection with this Agreement and the transactions contemplated by this Agreement shall be paid by the Party incurring such costs and expenses.

(f) Successors and Assigns; Third-Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of each Party and its successors, heirs, legal representatives and permitted assigns. Except as provided in the provisions of this Agreement related to indemnification, Secured Tower Operator Loans and Tower Operator Lender protections (including Section 21), this Agreement is not intended to confer upon any Person other than the Parties any rights or remedies hereunder.

(g) Amendment; Waivers; Etc. No amendment, modification or discharge of this Agreement, and no waiver hereunder, shall be valid or binding unless set forth in writing and duly executed by the Party against which enforcement of the amendment, modification, discharge or waiver is sought. Any such waiver shall constitute a waiver only with respect to the specific matter described in such writing and shall in no way impair the rights of the Party granting such waiver in any other respect or at any other time. The waiver by a Party of a breach of or a default under any of the provisions of this Agreement or to exercise any right or privilege hereunder, shall not be construed as a waiver of any other breach or default of a similar nature, or as a waiver of any of such provisions, rights or privileges hereunder. The rights and remedies herein provided are cumulative and none is exclusive of any other, or of any rights or remedies that any party may otherwise have at law or in equity.

(h) Time of the Essence. Time is of the essence in this Agreement, and whenever a date or time is set forth in this Agreement, the same has entered into and formed a part of the consideration for this Agreement.

(i) Specific Performance. The Parties agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof and that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in any of the Chosen Courts to the extent permitted by applicable Law, in addition to any other remedy to which they are entitled at law or in equity. Each Party hereby waives any requirement for security or the posting of any bond or other surety in connection with any temporary or permanent award of injunctive, mandatory or other equitable relief. Subject to Section 37(b) and Section 37(j) of this Agreement, nothing contained in this Agreement shall be construed as prohibiting any Party from pursuing any other remedies available to it pursuant to the provisions

-86-

of this Agreement or applicable Law for such breach or threatened breach, including the recovery of damages.

(j) Limitation of Liability. Notwithstanding anything in this Agreement to the contrary, neither Party shall have any liability under this Agreement, for: (y) any punitive or exemplary damages, or (z) any special, consequential, incidental or indirect damages, including lost profits, lost data, lost revenues and loss of business opportunity, whether or not the other Party was aware or should have been aware of the possibility of these damages.

(k) Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, the Parties hereto shall negotiate in good faith to modify this Agreement so as to (i) effect the original intent of the Parties as closely as possible and (ii) to ensure that the economic and legal substance of the transactions contemplated by this Agreement to the Parties is not materially and adversely affected as a result of such provision being invalid, illegal or incapable of being enforced, in each case, in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible. If following the modification(s) to this Agreement described in the foregoing sentence, the economic and legal substance of the transactions contemplated by this Agreement are not affected in any manner materially adverse to any Party, all other conditions and provisions of this Agreement shall remain in full force and effect.

(l) Interpretation.

(i) The table of contents and headings herein are for convenience of reference only, do not constitute part of this Agreement and shall not be deemed to limit or otherwise affect any of the provisions hereof.

(ii) The Parties have participated jointly in negotiating and drafting this Agreement.

SECTION 38. AT&T Guarantor Guarantee.

(a) As of the date hereof, AT&T Guarantor holds all or substantially all of AT&T Parent’s United States domestic wireless business (including wireless voice and data and the assets for the United States domestic wireless business). In the event AT&T Guarantor does not hold all or substantially all of AT&T Parent’s United States domestic wireless business (including wireless voice and data and the assets for the United States domestic wireless business) and AT&T Parent or another Affiliate of AT&T Parent does hold all or substantially all of AT&T Parent’s United States domestic wireless business (and all or substantially all of the United States domestic wireless business (including wireless voice and data and the assets for the United States domestic wireless business) of AT&T Guarantor shall not have been transferred to a Person that is not an Affiliate of AT&T Parent), AT&T Parent or such other Affiliate of AT&T Parent shall execute a joinder to this Agreement reasonably satisfactory to Tower Operator

-87-

providing for a guarantee of the AT&T Obligations equivalent to the guarantee provided by AT&T Guarantor as of the date hereof and shall become “AT&T Guarantor” for all purposes hereunder. For purposes of this section, the term “United States” shall include Puerto Rico and the United States Virgin Islands.

(b) AT&T Guarantor unconditionally guarantees to the Tower Operator Indemnitees the full and timely payment and performance and observance of all the terms, provisions, covenants and obligations of the AT&T Lessors and AT&T Ground Lease Parties under this Agreement (collectively, the “AT&T Obligations”). AT&T Guarantor agrees that if an AT&T Lessor or AT&T Ground Lease Party defaults at any time during the Term of this Agreement in the performance of any of the AT&T Obligations, AT&T Guarantor shall faithfully perform and fulfill all AT&T 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 an AT&T Lessor or AT&T Ground Lease Party and on account of the enforcement of this guaranty.

(c) The foregoing guaranty obligation of AT&T Guarantor shall be enforceable by any Tower Operator Indemnitee in an action against AT&T Guarantor without the necessity of any suit, action or proceeding by the applicable beneficiary of any kind or nature whatsoever against an AT&T Lessor or AT&T Ground Lease Party, without the necessity of any notice to AT&T Guarantor of an AT&T Lessor’s or AT&T Ground Lease Party’s default or breach under this Agreement, and without the necessity of any other notice or demand to AT&T Guarantor to which AT&T Guarantor might otherwise be entitled, all of which notices AT&T Guarantor hereby expressly waives. AT&T Guarantor hereby agrees that the validity of this guaranty and the obligations of AT&T Guarantor hereunder shall not be terminated, affected, diminished or impaired by reason of the assertion or the failure to assert by any Tower Operator Indemnitee against an AT&T Lessor or AT&T Ground Lease Party any of the rights or remedies reserved to such Tower Operator Indemnitee pursuant to the provisions of this Agreement or any other remedy or right which such Tower Operator Indemnitee may have at law or in equity or otherwise.

(d) AT&T Guarantor covenants and agrees that this guaranty is an absolute, unconditional, irrevocable and continuing guaranty. The liability of AT&T Guarantor hereunder shall not be affected, modified or diminished by reason of any assignment, renewal, modification, extension or termination of this Agreement or any modification or waiver of or change in any of the covenants and terms of this Agreement by agreement of an Tower Operator Indemnitee and an AT&T Lessor or AT&T Ground Lease Party, or by any unilateral action of an Tower Operator Indemnitee, an AT&T Lessor or an AT&T Ground Lease Party, or by an extension of time that may be granted by an Tower Operator Indemnitee to an AT&T Lessor or AT&T Ground Lease Party or any indulgence of any kind granted to an AT&T Lessor or AT&T Ground Lease Party, or any dealings or transactions occurring between an Tower Operator Indemnitee and an AT&T Lessor or AT&T Ground Lease Party, including any adjustment, compromise, settlement, accord and satisfaction or release, or any Bankruptcy, insolvency, reorganization or other arrangements affecting an AT&T Lessor or AT&T Ground Lease Party. AT&T Guarantor does hereby expressly waive any suretyship defenses it might otherwise have.

(e) All of the Tower Operator Indemnitees’ 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 to the exclusion of or a waiver of any other. AT&T Guarantor hereby waives presentment demand for performance, notice of nonperformance, protest notice of protest, notice of dishonor and notice of acceptance. AT&T Guarantor further waives any right to require that an action be brought against an AT&T Lessor or AT&T Ground Lease Party or any other Person or to require that resort be had by a beneficiary to any security held by such beneficiary.

SECTION 39. AT&T Parent Affiliate License. In the event that AT&T Guarantor ceases to be wholly owned, directly or indirectly, by AT&T Parent, to the extent that any Person that is directly or indirectly wholly owned by AT&T Parent but that is not directly or indirectly wholly owned by AT&T Guarantor used any Site as of the date AT&T Guarantor ceased to be directly or indirectly wholly owned by AT&T Parent (such Person, an “AT&T Parent Affiliate”), such AT&T Parent Affiliate and Tower Operator shall, following AT&T Parent Affiliate’s completion of the applicable application and amendment process, enter into definitive documentation reasonably satisfactory to Tower Operator to permit such AT&T Parent Affiliate to continue to use such Site (the “AT&T Parent Affiliate License”), in each case at the sole cost and expense of such AT&T Parent Affiliate. The AT&T Parent Affiliate License shall provide that such AT&T Parent Affiliate may continue to use the applicable Site subject to the terms of the MPL Site MLA solely to the extent that such AT&T Parent Affiliate used such Site as of the date AT&T Guarantor ceased to be directly or indirectly wholly owned by AT&T Parent, at no additional rent to such AT&T Parent Affiliate; provided, however, that the AT&T Parent Affiliate License shall provide that such AT&T Parent Affiliate shall pay customary and reasonable rent with respect to any use of any portion of such Site (including the AT&T Collocation Space at such Site) first used by such AT&T Parent Affiliate on or after the date that is one year prior to the earlier of (a) the first public announcement of the transaction pursuant to which AT&T Guarantor ceased to be directly or indirectly wholly owned by AT&T Parent and (b) the date on which definitive documentation was entered into with respect to the transaction pursuant to which AT&T Guarantor ceased to be directly or indirectly wholly owned by AT&T Parent. For the avoidance of doubt, (i) any portion of any Site (including the AT&T Collocation Space at such Site) used from time to time by any AT&T Parent Affiliate shall be deemed to be used by AT&T Collocator for all purposes under MPL Site MLA and (ii) except as otherwise expressly provided in the AT&T Parent Affiliate License or other definitive documentation entered into by Tower Operator and AT&T Parent Affiliate, AT&T Parent Affiliate shall use the applicable Site (including the AT&T Collocation Space at such Site) only to the extent permitted under the MPL Site MLA (including Section 9(b) thereof).
