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.

following request therefor by Manager, any document referred to in this
Section 3(e) and any other document contemplated and permitted by this Agreement
or a Collateral Agreement or necessary to give effect to the intent of this
Agreement, the Master Agreement and the other Collateral Agreements. Except as

restrictions imposed upon it by this Agreement and the Collateral Agreements.

that it is party to the MPL as an “AT&T Lessor” thereunder. Each AT&T
Contributor acknowledges and agrees that it is an “AT&T Ground Lease Party”
under and for purposes of the MPL and, without limiting in any respect the
duties of such AT&T Contributor under Section 3(a), agrees to be bound by all
provisions of the MPL applicable to the AT&T Ground Lease Parties with the same
force and effect, and to the same extent, as if such AT&T Contributor were a
party to the MPL in such capacity.
