AGREEMENT 
 In
consideration of the foregoing and the representations, warranties, and agreements contained in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and intending to be legally
bound by this Agreement, the Parties agree as follows: 
 Section 1. Appointment and Acceptance. Subject to the
terms and conditions of this Agreement, (a) each applicable AT&T Contributor and AT&T Newco hereby appoints Manager, and Manager hereby agrees to act and shall act, as the exclusive operator during the MPL Site Term (as defined below)
of the Included Property of each Managed MPL Site held by such AT&T Contributor or AT&T Newco and (b) each applicable AT&T Contributor hereby appoints Manager, and Manager hereby agrees to act and shall act, as the exclusive
operator during the Sale Site Term (as defined below) of the Included Property of each Managed Sale Site held by such AT&T Contributor. Notwithstanding anything to the contrary in this Agreement or in the Collateral Agreements, no fee title,
leasehold, subleasehold or other real property interest in a Managed Site is granted pursuant to this Agreement in the Included Property of any Managed Site; provided, however, that for U.S. federal income Tax purposes this Agreement
shall be treated as a lease of the Included Property of the Managed Sites (except the Managed Sale Sites), and the Parties further agree not to take any position on any Tax return that is inconsistent with such treatment, except as otherwise
required by Law or Order. The rights granted to Tower Operator under this Agreement include, with respect to each Managed Site, the right of Tower Operator to use and employ the Tower Related Assets related to the Tower on such Managed Site. In
performing its duties as operator of the Included Property of the Managed MPL Sites, Manager shall manage, administer and operate each of the Managed MPL Sites, subject to the provisions of this Agreement, in a manner consistent with and not less
than the standards Tower Operator uses to manage, administer and operate the Lease Sites under the terms of the MPL. Notwithstanding anything to the contrary set forth in this Agreement, Manager shall be entitled to and vested with all the rights,
powers and privileges of the applicable AT&T Contributor or AT&T Newco with respect to the management, administration and operation of the Included Property of the Managed Sale Sites as if Manager were the true owner of such rights, powers
and privileges of the applicable AT&T Contributor or AT&T Newco with respect to the management, administration and operation of the Included Property of the Managed Sale Sites, including the right to review, negotiate and execute extensions,
renewals, amendments or waivers of any existing collocation agreements, ground leases, 

  
 -2- 








 
subleases, easements, licenses or other similar or related agreements or new collocation agreements, ground leases, subleases, easements, licenses or similar or related other agreements. Except
as expressly provided herein or, with respect to the Managed MPL Sites, in the MPL, no AT&T Contributor or AT&T Newco 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 Manager hereunder. 
 Section 2.
Collocation Agreements for Managed Sites. 
 (a) In respect of the Included Property of each Managed Site, the
applicable AT&T Contributor and each AT&T Newco 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 Manager for the MPL Site Term or Sale Site Term, as applicable, as to such Included Property for periods occurring from and after the Effective Date, and shall execute all documentation reasonably requested and prepared by Manager to
confirm same to a counterparty under a Collocation Agreement, at Manager’s sole cost and expense within 15 Business Days of receipt of a request therefor from Manager; provided, however, that, if such AT&T Contributor or
AT&T Newco reasonably determines it to be unduly burdensome, such AT&T Contributor or AT&T Newco 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. Manager 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 (including site supplements or site subleases) applicable to the Managed Sites; provided that, in the case of the Managed MPL Sites, the provisions of
Section 2(d) of the MPL shall apply to all such actions by Manager, mutatis mutandis. Each AT&T Contributor and AT&T Newco hereby (i) assigns and delegates to Manager the sole and exclusive right to perform the obligations
of and assert and exercise the rights of such AT&T Contributor or AT&T Newco under all Collocation Agreements during the MPL Site Term or Sale Site Term, as applicable, with respect to Managed Sites, subject to, in the case of the Managed
MPL Sites, the provisions of Section 2(d) of the MPL, and (ii) hereby grants Tower Operator a limited power of attorney and hereby appoints Tower Operator as its attorney in fact to assert and exercise the rights of such AT&T
Contributor or AT&T Newco under all Collocation Agreements during the MPL Site Term or Sale Site Term, as applicable. 

(b) Manager does hereby assume and agree to pay and perform all of the duties, obligations, liabilities and responsibilities
of the AT&T Contributors and AT&T Newcos under the Collocation Agreements affecting each Managed Site arising during the MPL Site Term or the Sale Site Term, as applicable, except as otherwise expressly provided in this Agreement or any
Collateral Agreement, and Manager 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. The expiration of this Agreement with respect to any Managed Site, whether by reason of conversion of such Managed Site to a Lease Site or
Assignable Site or otherwise, shall not release Manager of any obligations in respect of such Managed Site arising during the MPL Site Term or Sale Site Term, as applicable. 

  
 -3- 








 (c) Manager shall be permitted to negotiate and enter into, amend or modify any
new or existing collocation agreements (including site supplements or site subleases) in its sole discretion, without the consent of any AT&T Contributor or AT&T Newco, subject, in the case of any Managed MPL Sites, to
Section 2(d) of the MPL (including Section 2(d)(C) thereof), mutatis mutandis.
