(e)T-Mobile Right to Cure Ground Rent Defaults. If Tower Operator does not pay all or any portion of the Ground Rent when due and payable with respect to any Leased Site, T-Mobile Collocator may seek to cure such payment default under any applicable Ground Lease by making payment of the unpaid Ground Rent to the applicable Ground Lessor. Within 10 days following receipt of any invoice therefor, Tower Operator shall reimburse T-Mobile Collocator for all such payments of Ground Rent made by T-Mobile Collocator. If such reimbursement is not made within such 10-day period, T-Mobile Collocator may offset all such payments of Ground Rent made by T-Mobile Collocator against the T-Mobile Collocation Rent that may be due and payable from T-Mobile Collocator to Tower Operator under this Agreement.

SECTION 5.Ground Leases.

(a)Compliance With Ground Leases. Tower Operator shall promptly pay or cause to be paid the Ground Rent under each Ground Lease for each of the Sites during the Term of this

Agreement when such payments become due and payable. With respect to the Non-Assignable Sites, 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 no event shall Tower Operator have any liability to any T-Mobile Group Member for any breach of, or default under, a Ground Lease caused by an act or omission of any T-Mobile Group Member.

(b)Exercise of Existing Ground Lease Extensions. During the Term of any Ground Lease relating to any Site, Tower Operator agrees to 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 Effective Date. Notwithstanding the foregoing, Tower Operator shall not be required to exercise any Ground Lease extension option (A) if T-Mobile Collocator at the Site covered by such Ground Lease is in default of its obligations under this Agreement as to the Site beyond applicable notice and cure periods provided herein, (B) if the then remaining term of such Ground Lease (determined without regard to such extension option) shall extend beyond the term of this Agreement as to such Site taking into account all renewal options that may be exercised by T-Mobile Collocator under this Agreement or (C) if T-Mobile Collocator has given a Termination Notice relating to such Site.

(c)Negotiation of Additional Ground Lease Extensions. T-Mobile Collocator, if requested by Tower Operator, shall use commercially reasonable efforts to assist Tower Operator (and not interfere with Tower Operator) in obtaining further extensions of the term of any Ground Lease; provided that T-Mobile Collocator shall not be required to expend any funds in connection therewith.

(d)This Section 5 shall not apply to the CA/NV Master Lease, which shall be governed by Section 33.

(a)Repair and Maintenance of Tower.

(i)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.

(ii)Reserved T-Mobile Loading Capacity. Tower Operator shall make structural modifications to any Tower when and to the extent necessary to provide sufficient structural loading capacity to enable T-Mobile Collocator to install the T-Mobile Reserved Amount of Tower Equipment in the T-Mobile Primary Tower Space on such Tower (the “Reserved T-Mobile Loading Capacity”), subject to obtaining all necessary Governmental Approvals and other approvals and further subject to the following:

(A) Tower Operator shall only be responsible for the costs of structural modifications to any Tower (including costs related to structural analysis, Governmental Approvals and other approvals) to increase the structural loading capacity:

(1) to enable Tower Operator to permit any Person other than T-Mobile Collocator to install Communications Equipment; and

(2) during the period beginning on the Effective Date and ending on the second anniversary of the Effective Date (the “T-Mobile Modernization Reservation Period”), to provide the portion of the Reserved T-Mobile Loading Capacity that (x) existed on such Tower but was not being used by T-Mobile Collocator as of the Effective Date (“Unused Existing Effective Date Capacity”), (y) is unavailable at the time that T-Mobile Collocator installs the T-Mobile Reserved Amount of Equipment and (z) is unavailable due to the prior installation (following the Effective Date) of Communications Equipment by any Tower Tenant or Tower Operator; and

(B) Tower Operator shall not be responsible for the costs of structural modifications to any Tower (including costs related to structural analysis, Governmental Approvals and other approvals) to increase the structural loading capacity:

(1) to provide the portion of the Reserved T-Mobile Loading Capacity in excess of the Unused Existing Effective Date Capacity;

(2) during the T-Mobile Modernization Reservation Period, to provide the portion of the Unused Existing Effective Date Capacity that is unavailable at the time T-Mobile Collocator installs the T-Mobile Reserved Amount of Equipment due to a change in applicable Law that became effective after the Effective Date; or

(3) to enable the installation of any T-Mobile Communications Equipment after the T-Mobile Modernization Reservation Period.

(iii)Tower Operator Right to Install Equipment. Tower Operator shall have the right to install its own Communications Equipment or Tower Tenant Communications Equipment (collectively, “Third Party Communications Equipment”) outside of the T-Mobile Collocation Space during or after the T-Mobile Modernization Reservation Period subject to the provisions of Section 6(a)(ii); provided, however, that if the application to install Third Party Communications Equipment is made after the T-Mobile Modernization Reservation Period and after Tower Operator has received an application from T-Mobile Collocator to install any of the T-Mobile Reserved Amount of Tower Equipment (regardless of whether such application from T-Mobile Collocator is made before or after the end of the T-Mobile Modernization Reservation Period), Tower Operator shall, to the extent sufficient structural loading capacity exists and provided that (x) T-Mobile Collocator's application to install the T-Mobile Reserved Amount of Tower Equipment set forth in its application is approved and (y) the installation of the T-Mobile Reserved Amount of Tower Equipment occurs not later than 180 days after completion of structural review, allocate the currently available loading capacity first to the subject T-Mobile Reserved Amount of Tower Equipment and then to the subject Third Party Communications Equipment. Notwithstanding the

exclusivity of the T-Mobile Primary Tower Space, Tower Operator and Tower Tenants and their employees, contractors and agents shall have the right to enter the T-Mobile Primary Tower Space at any time, without notice to T-Mobile Collocator, to access other portions of the Tower and to install, operate, inspect, repair, maintain and replace Cables together with related mounting hardware and incidental equipment and to install, operate, inspect, repair, maintain, make improvements to and perform work on the Tower, tower-related components and equipment within the T-Mobile Primary Tower Space.

(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 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 T-Mobile Collocator shall be responsible and shall indemnify Tower Operator 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. T-Mobile Collocator assumes all responsibilities, as to each Site, for any fines, levies or other penalties imposed as a result of T-Mobile Collocator's current or future non-compliance with such requirements of the applicable Governmental Authorities unless due to Tower Operator's failure to perform its obligations under this Agreement. 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 T-Mobile Collocator 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, 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 T-Mobile Collocator.

SECTION 7.Tower Operator Modifications.

Tower Operator may from time to time make such Modifications as Tower Operator deems desirable in the proper conduct of its business in accordance with this Agreement, including the addition or removal of land, construction, modification or addition to the Tower or any other structure it owns or the reconstruction, replacement or alteration thereof. Notwithstanding anything to the contrary contained herein, in no event may Tower Operator make any Modification to any T-Mobile Improvement or modify or replace any T-Mobile Communications Equipment except in the event of an Emergency.

SECTION 8.T-Mobile Collocator's and Tower Operator's Obligations With Respect to Tower Tenants; Interference.

(a)Interference to T-Mobile Collocator's Operations. Tower Operator agrees that neither Tower Operator nor any Tower Tenant whose Communications Equipment is installed or

modified (including modifying the frequency at which such equipment is operated) subsequently to T-Mobile Communications Equipment (a “Subsequent Use”), shall permit their equipment to interfere with T-Mobile Collocator's permitted FCC licensed transmissions or reception. In the event that T-Mobile Collocator experiences RF interference in excess of levels permitted by the FCC caused by such Subsequent Use, then (i) T-Mobile Collocator shall notify Tower Operator in writing of such RF interference and (ii) Tower Operator shall use commercially reasonable efforts to cause the party whose Subsequent Use is causing such RF interference to immediately take necessary steps to determine the cause of and eliminate such RF interference. If such interference continues for a period in excess of 72 hours after Tower Operator's receipt of notice from T-Mobile Collocator, Tower Operator shall request that Tower Tenant reduce power or cease operations until such time as Tower Tenant can make repairs to the interfering equipment. In the event that such Tower Tenant fails to promptly reduce power or cease operations as requested, then Tower Operator shall terminate the operation of the Communications Equipment causing such RF interference at Tower Operator's (or such Tower Tenant's) cost if and to the extent permitted by the terms of any applicable Collocation Agreements.

(b)Interference by T-Mobile Collocator. Notwithstanding any prior approval by Tower Operator of T-Mobile Communications Equipment, T-Mobile Collocator agrees that it shall not allow T-Mobile Communications Equipment installed or modified subsequently to any Tower Operator or Tower Tenant's Communications Equipment to cause RF interference to Tower Operator's or any Tower Tenant's permitted FCC licensed transmissions or reception in excess of levels permitted by the FCC. If T-Mobile Collocator is notified in writing that its operations are causing such RF interference, T-Mobile Collocator shall immediately take all commercially reasonable efforts and necessary steps to determine the cause of and eliminate such RF interference. If the interference continues for a period in excess of 72 hours following such notification, Tower Operator shall have the right to require T-Mobile Collocator to reduce power or cease operations until such time as T-Mobile Collocator can make repairs to the interfering Communications Equipment. In the event that T-Mobile Collocator fails to promptly take such action as agreed, then Tower Operator shall have the right to terminate the operation of the Communications Equipment causing such RF interference, at T-Mobile Collocator's cost, and notwithstanding anything to the contrary contained herein without liability to Tower Operator for any inconvenience, disturbance, loss of business or other damage to T-Mobile Collocator as the result of such actions. T-Mobile Collocator also agrees that it shall neither install T-Mobile Communications Equipment nor subsequently modify it such that it is not authorized by, or violates, any applicable Laws or is not made or installed in accordance with good engineering practices.

(c)Rights of Tower Tenants under Collocation Agreements. Notwithstanding anything to the contrary contained herein, the obligations of Tower Operator hereunder as to any Site are subject to any limitations imposed by any applicable Law and to the rights of any Tower Tenant 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, 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 T-Mobile Collocator.

SECTION 9.T-Mobile Collocation Space.

(a)Collocation Space. As used herein, “T-Mobile Collocation Space,” as to each Site, means:

(i)The portions of the Land comprising such Site on which any portion of the T-Mobile Improvements or T-Mobile Communications Equipment is located, operated or maintained as of the Effective Date, including the air space above such portion of the Land, to the extent such air space is not occupied by a third party or the tower or Communications Equipment owned by Tower Operator on the Effective Date (the “Effective Date Ground Space”). In the event that T-Mobile Collocator, as of the Effective Date, occupies less than 240 square feet of Land at such Site, T-Mobile Collocator shall have the exclusive right to occupy up to a maximum area of 240 square feet of contiguous and usable ground space in a 12 foot by 20 foot configuration and the air space above such ground space, to the extent such air space is not occupied by a Tower or Communications Equipment on such Tower or otherwise by a third party on the Effective Date and such space shall be part of the T-Mobile Collocation Space (the greater of such space and the Effective Date Ground Space, the “T-Mobile Primary Ground Space”). The T-Mobile Primary Ground Space at any Site shall be documented in the Site Lease Agreement for such Site. If contiguous and usable ground space is not available at a Site in a 12 foot by 20 foot configuration, T-Mobile Collocator shall have the exclusive right to occupy 240 square feet of contiguous and usable ground space such Site in such configuration as T-Mobile Collocator elects and such space shall be deemed to be the T-Mobile Primary Ground Space at such Site and shall be documented in the Site Lease Agreement for such Site. If on the Effective Date, at any Site there is less than 240 square feet of ground space available for T-Mobile Collocator's exclusive use within such Site, the T-Mobile Primary Ground Space at such Site shall be the ground space within such Site occupied by T-Mobile Collocator on the Effective Date and any additional available ground space within such Site on the Effective Date, and the T-Mobile Primary Ground Space shall be documented in the Site Lease Agreement for such Site. Notwithstanding the foregoing, if a Site has less than 1,000 square feet of ground space in the aggregate and T-Mobile Collocator's Effective Date Ground Space is less than 240 square feet within such Site, then Tower Operator shall not be obligated to reserve any additional ground space available within such Site as of the Effective Date for T-Mobile Collocator, and the Effective Date Ground Space shall be documented in the Site Lease Agreement for such Site as the T-Mobile Primary Ground Space, and Tower Operator may, at any time during the Term of this Agreement, use or permit a Tower Tenant to use any ground space that is not then being used by T-Mobile Collocator as part of the Effective Date Ground Space without obtaining T-Mobile Collocator's consent; provided, however, that if, at any point after the Effective Date, T-Mobile Collocator desires to use additional ground space and increase its T-Mobile Primary Ground Space within such Site to up to 240 square feet and such space is not then being used (including committed to use) by Tower Operator or a Tower Tenant, T-Mobile Collocator shall have the right, after completion of the application and amendment process described in Section 9(e) and entering into an amendment to the Site Lease Agreement for such Site, to increase the T-Mobile Primary Ground Space within such Site to up to 240 square feet by adding such additional ground space and to use such additional ground space at no additional cost to T-Mobile Collocator. If there is insufficient ground space at any Site for the use of other Tower Tenants, Tower Operator shall have the right to permit such other Tower Tenants, at their sole cost and expense, to stack ground equipment above the ground equipment maintained by T-Mobile Collocator in the T-Mobile Primary Ground Space;

(ii)The portion of the Tower on such Site on or within which any portion of T-Mobile Communications Equipment is located, operated or maintained (including portions of the Tower on which any antennas, transmission lines, amplifiers, filters and other Tower mounted equipment are located) as of the Effective Date (the “Effective Date Tower Space”). In the event T- Mobile Collocator occupies less than eight contiguous vertical feet of space on such Tower, T-Mobile Collocator's exclusive reserved space on such Tower shall include any additional and unoccupied

vertical space adjacent to the space occupied by T-Mobile Collocator as is necessary to provide T-Mobile Collocator with such eight contiguous vertical feet of space on such Tower which shall be four contiguous feet of vertical space on each Tower above and below the T-Mobile Primary Tower Space RAD Center on such Tower on the Effective Date (eight feet of vertical space in total) (the greater of such space or the Effective Date Tower Space, the “T-Mobile Primary Tower Space”). Notwithstanding the exclusivity of the T-Mobile Primary Tower Space, Tower Operator and Tower Tenants and their employees, contractors and agents shall have the right to enter the T-Mobile Primary Tower Space at any time, without notice to T-Mobile Collocator, to access other portions of the Tower and to install, operate, inspect, repair, maintain and replace Cables together with related mounting hardware and incidental equipment and to install, operate, inspect, repair, maintain, make improvements to and perform work on the Tower, tower-related components and equipment within the T-Mobile Primary Tower Space. If such additional space is occupied by a Tower Tenant on the Effective Date or such configuration is prohibited by Law, Tower Operator shall be required to provide only such additional space as is available or allowed by Law, as applicable. Notwithstanding the foregoing, with respect to Towers that are less than 100 feet in height, upon obtaining T-Mobile Collocator's prior written consent, which consent cannot be subject to any conditions and cannot be unreasonably withheld or delayed (and T-Mobile Collocator's failure to respond to such notice within 10 Business Days shall be deemed to constitute consent thereto), Tower Operator shall have the right to install Communications Equipment of other Tower Tenants within the T-Mobile Primary Tower Space; provided that such Communications Equipment may not be installed within the vertical envelope of space then occupied by the primary antenna array of the T-Mobile Communications Equipment located within the T-Mobile Primary Tower Space;

(iii)Any Additional Ground Space;

(iv)Any and all rights pursuant to Section 9(c), Section 9(d), Section 9(g), Section 9(h) and Section 10 and all appurtenant rights reasonably inferable to permit T-Mobile Collocator's full use and enjoyment of the T-Mobile Collocation Space including the rights specifically described in this Section 9, all in accordance with this Section 9; and

(v)Tower Operator shall prevent and eliminate obstructions on a Site that prevent T-Mobile Collocator from having access to repair and replace all of the T-Mobile Communications Equipment and T-Mobile Improvements (including related Cables) or from being able to fully open any equipment cabinet doors in such space and repair and replace equipment therein.

(b)T-Mobile Collocator Permitted Use. T-Mobile Collocator shall use the T-Mobile Collocation Space at each Site only for installation, modification, use, operation, repair and replacement of T-Mobile's Communications Facility. T-Mobile Collocator shall not use the T-Mobile Collocation Space at any Site in a manner that would reasonably be expected to materially impair Tower Operator's rights or interest in such Site or in a manner that would reasonably make possible a Claim or Claims of adverse possession by the public, as such, or any other Person (other than T-Mobile Collocator), or of implied dedication of such T-Mobile Collocation Space. Except as specifically permitted hereunder, T-Mobile Collocator shall have no right to use or occupy any space at any Site other than the T-Mobile Collocation Space that it occupies from time to time in accordance with the terms of this Agreement nor to share the use of its T-Mobile Collocation Space with any Affiliate or third party (except with exclusive Backhaul Operators as specifically permitted in Section 19(c)). T-Mobile Collocator's use of the T-Mobile Collocation Space and its Communication Equipment (except as specifically permitted hereunder) shall not compete with Tower Operator's collocation business, operations or collocation activities at the Sites or in any

way prevent, diminish, hinder or interfere with Tower Operator's opportunity to derive collocation revenue from the Sites (it being understood and agreed that the foregoing would prohibit T-Mobile Collocator from utilizing the T-Mobile Collocation Space or its Communication Equipment to engage in network hosting without entering into a collocation agreement with Tower Operator that permits such use (which collocation agreement must be reasonably satisfactory to Tower Operator and provide additional compensation to Tower Operator)). Notwithstanding anything to the contrary herein, T-Mobile Collocator shall be permitted to use the radio frequency signal generated by the T-Mobile Communications Equipment to provide third parties with customary, industry standard roaming or mobile virtual network services.

(c)Reserved Amount of Tower Equipment in T-Mobile Collocation Space. As to each Site, T-Mobile Collocator shall have the right, at any time, to install, maintain, modify, replace and operate in the T-Mobile Collocation Space on the Tower any Communications Equipment consisting of the greater of (i) antennas, remote radio units and associated tower mounting equipment having an aggregate Wind Load Surface Area of 21,000 square inches and up to 24 lines of Cables or (ii) antennas (including microwave antennas and dishes), remote radio units and associated tower mounting equipment and Cables having an aggregate Wind Load Surface Area that is not in excess of the aggregate Wind Load Surface Area of the antennas, remote radio units and associated tower mounting equipment and Cables located on the applicable Tower as of the Effective Date (collectively, the “T-Mobile Reserved Amount of Tower Equipment”). Schedule 9(c) attached hereto contains sample calculations of the Wind Load Surface Area for hypothetical configurations of Communications Equipment; provided that the example calculations set forth in Schedule 9(c) are intended as examples only and not as a limitation or prescription on the configurations of the actual T-Mobile Communications Equipment. The foregoing shall not limit T-Mobile Collocator's rights to place in the T-Mobile Collocation Space on a Tower, panel antennas or Cables of different size or structural loading characteristics or equipment of a different shape or technology or a different transmission frequency than that which exists on such Tower on the Effective Date; provided that (x) T-Mobile Collocator shall comply with Tower Operator's standard application and amendment process set forth in Section 9(e) and (y) such antennas, Cables and equipment do not exceed the Wind Load Surface Area and the structural loading capacity of the T-Mobile Reserved Amount of Tower Equipment. Subject to the foregoing limitations, as to each Site, T-Mobile Collocator shall have the right to install, maintain, modify, replace and operate, at no additional collocation rent, any Communications Equipment and Improvements that it deems necessary in the T-Mobile Primary Ground Space. All modifications, additions and replacements of any Communications Equipment in the T-Mobile Collocation Space on the Tower that do not constitute Additional Equipment pursuant to Section 9(d) may be made without any increase in the T-Mobile Collocation Rent. Notwithstanding the above, the windloading of Communications Equipment on a Tower for structural capacity and other purposes shall be determined in accordance with Tower Operator's standard protocols and procedures for determining effective projected area. Exhibit E attached hereto contains sample calculations of the effective projected area for the hypothetical configuration of Communications Equipment set forth in Schedule 9(c).

(d)Additional T-Mobile Communications Equipment In the T-Mobile Collocation Space. T-Mobile Collocator may apply to Tower Operator to install, maintain, modify, replace and operate Communications Equipment in the T-Mobile Primary Tower Space in excess of the T-Mobile Reserved Amount of Tower Equipment (collectively “Additional Equipment”); provided that there is sufficient structural load capacity available on the Tower at the time T-Mobile Collocator applies to install such Additional Equipment. The application shall be processed and an amendment

to the subject Site Lease Agreement shall be executed to document any Additional Equipment or any changes to existing equipment as of the Effective Date in accordance with Section 9(e).

(e)Application and Amendment Process.

(i)T-Mobile Collocator's rights to install and operate any T-Mobile Communications Equipment at a Site in addition to or in replacement of the T-Mobile Communications Equipment existing at the Site as of the Effective Date shall not become effective, and installation of such additional T-Mobile Communications Equipment or modification of the existing T-Mobile Communications Equipment at a Site shall not commence, until the following conditions are satisfied: (A) Tower Operator has received any written consent required under the Ground Lease to allow Tower Operator to permit such installation or modification, (B) T-Mobile Collocator has submitted to Tower Operator and Tower Operator has approved T-Mobile Collocator's application for such installation or modification (a “Site Engineering Application”); (C) Tower Operator has received and approved T-Mobile Collocator's drawings showing the installation or modification of the T-Mobile Communications Equipment; (D) Tower Operator has reviewed and accepted all permits obtained by T-Mobile Collocator for its installation or Modification of the T-Mobile Communications Equipment and all required regulatory or governmental approvals of T-Mobile Collocator's proposed installation or modification at the Site; (E) Tower Operator has received a waiver of any applicable rights of first refusal in and to the space in which any new equipment shall be located as identified by T-Mobile Collocator in the Site Engineering Application; (F) any Site Application Fee, Application Revision Fee, Inspection Fee for Third Party Work, Regulatory Fees, Structural Analysis Fee, Intermodulation Study Fee and fee for AM Detuning Study and any other applicable fees have been paid (such fees shall be determined from time to time in accordance with Tower Operator's current business practices and prevailing rates), (G) a Site Lease Agreement and an amendment to the Site Lease Agreement have been executed; and (H) Tower Operator has issued a notice to proceed with the proposed installation or modification; provided that if the conditions precedent listed in clauses (A) through (H) of this sentence are satisfied or determined not to be applicable, then Tower Operator's approval of the subject Site Engineering Application to install T-Mobile Communications Equipment that is within the T-Mobile Reserved Amount of Tower Equipment shall not be unreasonably withheld, conditioned or delayed. If any applicable condition precedent is not satisfied within 180 days of the date of the amendment of the subject Site Lease Agreement or within such other period as may be specified in the subject amendment of the Site Lease Agreement, Tower Operator and T-Mobile Collocator shall each have the right to terminate the subject amendment of the subject Site Lease Agreement. The terminating party shall provide notice to the other party in the event that the amendment of the subject Site Lease Agreement is terminated due to failure to satisfy conditions precedent. Tower Operator shall endeavor to obtain, and T-Mobile Collocator shall cooperate to assist in obtaining, prompt satisfaction of any conditions precedent.

(ii)T-Mobile Collocator must provide Tower Operator with copies of any zoning application or amendment that T-Mobile Collocator submits to the applicable zoning authority in relation to its installation or modification of Equipment at a Site at least 72 hours prior to submission to the applicable zoning authority. Tower Operator also reserves the right, prior to any decision by the applicable zoning authority, to approve or reject any conditions of approval, limitations or other obligations that would apply to the owner of the Site or property, or any existing or future Tower Tenant, as a condition of such zoning authority's approval and that would or could reduce the duration of the use of the subject Site or the operations thereon or decrease the value of the Site or its use or impair or impede Tower Operator's or the Tower Tenants' operations at the Site, or

create a risk of regulatory violations; provided, however, that Tower Operator shall not unreasonably reject any conditions of approval if none of the foregoing factors are present in Tower Operator's judgment and T-Mobile Collocator agrees to pay the cost of satisfying such conditions of approval. T-Mobile Collocator shall be solely responsible for all costs and expenses associated with (i) any zoning application or amendment submitted by T-Mobile Collocator, (ii) making any improvements or performing any other obligations required as a condition of approval with respect to same and (iii) any other related expenses.

(f)Lease; Appurtenant Rights. T-Mobile Collocator and Tower Operator expressly acknowledge that the T-Mobile Collocation Space at each Site shall be deemed leased to, reserved for or otherwise be made available to T-Mobile Collocator pursuant to this Agreement, in each case at each Site for the exclusive possession (subject to Section 9(a)(ii)) and use by T-Mobile Collocator (except as otherwise expressly provided herein), whether or not such T-Mobile Collocation Space is now or hereafter occupied. T-Mobile Collocator shall have the right to occupy at all times the portions of Land, the Improvements and Tower occupied as of the Effective Date and any additional space constituting T-Mobile Collocation Space and to repair, replace and modify any equipment of T-Mobile Collocator therein or thereon. Tower Operator also grants to T-Mobile Collocator as to each Site, and T-Mobile Collocator reserves and shall at all times retain (for the benefit of T-Mobile Collocator), subject to the terms of this Agreement, the Ground Leases, the rights of Tower Tenants and applicable laws:

(i)Site Access. A non-exclusive right and easement (over the surface of the Site) for ingress to and egress from the entire Site, and access to the entire Tower and all Improvements to such Site and Tower, 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), to such extent, and in such means and manners (on foot or by motor vehicle, including trucks and other heavy equipment), as T-Mobile Collocator (and its authorized contractors, subcontractors, engineers, agents, advisors consultants, representatives, or other persons authorized by T-Mobile Collocator) deems reasonably necessary in connection with its full use and enjoyment of the T-Mobile Collocation Space, including a right to construct, install, use, operate, maintain, repair and replace all of its equipment now or hereafter located in the applicable T-Mobile Collocation Space;

(ii)Tower Access. The right to undertake any activity that involves having T-Mobile Collocator or its contractors, subcontractors, engineers, agents, advisors, consultants, representatives, or other Persons authorized by T-Mobile Collocator climb the Tower at any Site; provided, however, that T-Mobile Collocator must ensure that any such Person must work for a vendor approved by Tower Operator; provided further that T-Mobile Collocator shall, except in the event of an Emergency, give Tower Operator at least one Business Day's prior written notice of its intention to exercise such right;

(iii)Storage. The right, exercisable during periods in which T-Mobile Collocator is actively performing work at a Site, to use any unoccupied portion of the ground space at the applicable Site for purposes of temporary location and storage of any of its equipment and for performing any repairs or replacements; provided, however, that T-Mobile Collocator shall be required to remove any of its stored Communications Equipment on any unoccupied portion of the Site upon 10 days' prior written notice from Tower Operator if such unoccupied portion of the Site is under sublease or other occupancy arrangement with a Tower Tenant that is prepared to take

occupancy of such portion of the Site or is otherwise required for use by Tower Operator for work or storage at such Site; and

(iv)Utility Lines. A non-exclusive right and easement for the use, operation, maintenance, repair and replacement of all utility lines, Cables and all equipment and appurtenances located on the Site and providing electrical, gas and any other utility service to T-Mobile's Communications Facility on the Site, which right and easement includes the right of T-Mobile Collocator and its agents, employees and contractors to enter upon the Site to repair, maintain and replace such utility facilities. T-Mobile Collocator shall have the absolute right to contract with any utility service providers it elects, from time to time, for utility services.

(g)Maintenance. T-Mobile Collocator shall, at all times during the Term as to any Site, at T-Mobile Collocator's sole cost and expense, keep and maintain T-Mobile Communications Equipment and T-Mobile Improvements in a structurally safe and sound condition and in working order, in accordance with the general standard of care in the telecommunications industry, subject to Tower Operator's obligations with respect to the maintenance, repair and reinforcement of the Tower hereunder.

(h)No Obligation With Respect to Communications Facility. In addition to, and not in limitation of any right of T-Mobile Collocator under Section 3, and notwithstanding anything in this Agreement to the contrary, without limiting or diminishing T-Mobile Collocator's payment obligations hereunder in any manner, including its obligation to pay T-Mobile Collocation Rent, T-Mobile Collocator shall not have any obligation to occupy or to operate a Communications Facility on the T-Mobile Collocation Space of any Site, and T-Mobile Collocator shall have the right, exercisable at any time during the Term as to any Site, to cease occupying or operating T-Mobile Collocator's Communications Facility on the T-Mobile Collocation Space of such Site, and retain its right to such T-Mobile Collocation Space.

(i)Restoration. T-Mobile Collocator shall restore any property damage (normal wear and tear excepted) to any Site or appurtenant property or any access roads thereto caused, following the Effective Date, by motor vehicles, trucks or heavy equipment of T-Mobile Collocator or any of its employees, agents, contractors or designees. If such restoration work is not performed by T-Mobile Collocator within 30 days after written notice from Tower Operator (or if not capable of being performed within such 30-day period, then within a reasonable period of time, provided that T-Mobile Collocator is actively and diligently pursuing completion of such restoration work), Tower Operator may, but shall not be obligated to perform such work on behalf of and for the account of T-Mobile Collocator, and T-Mobile Collocator shall reimburse Tower Operator for the reasonable costs of such restoration work within 30 days after Tower Operator delivers to T-Mobile Collocator a written invoice therefor, together with reasonable evidence of the incurrence of such costs. For the avoidance of doubt, any damage caused by T-Mobile Collocator to any Site or appurtenant property or access roads and any failure by T-Mobile Collocator to cure such damage as required hereby, shall not constitute a breach of or default by Tower Operator under this Agreement or give rise to any obligation by Tower Operator to indemnify T-Mobile Collocator's Indemnitees under this Agreement.

(j)Waiver. Tower Operator agrees to and does hereby waive and relinquish any lien of any kind and any and all rights, statutory or otherwise, including levy, execution and sale for unpaid rents, that Tower Operator may have or obtain on or with respect to any T-Mobile Communications

SECTION 10.Tower and Site Modifications, Replacement, Expansion and Substitution and Rights With Respect to Additional Ground Space and Tower Space.

(a)Tower and Site Modifications. With respect to any Site for which the structural capacity of the Tower is not sufficient as of the Effective Date to support the T-Mobile Reserved Amount of Tower Equipment, Tower Operator may, upon request by T-Mobile Collocator and at T-Mobile Collocator's cost and expense (as a T-Mobile Collocator capital expenditure, without any increase in the T-Mobile Collocation Rent or payment of any fee or charge to Tower Operator), make any Modifications to a Tower that it reasonably deems necessary to increase the structural capacity of such Tower to support the T-Mobile Reserved Amount of Tower Equipment; provided that the costs of such Modifications shall be as mutually agreed to by the Parties acting in good faith and shall be consistent with prevailing commercial prices at the relevant time. The structural loading capacity of a Tower and the structural loading thereon shall be determined based on a structural report obtained by Tower Operator at T-Mobile Collocator's cost. If Tower Operator increasing the height of a Tower at the request of T-Mobile Collocator results in a requirement for FAA mandated lighting of such Tower, T-Mobile Collocator shall pay the cost of installing such lighting, the cost of obtaining or amending the FCC Antenna Structure Registration for the Tower (“ASR”), including any environmental studies, and the cost of industry-standard lighting equipment for Tower Operator to monitor the lighting of such Tower, similar to the monitoring equipment at other lighted Sites and the reasonable and customary ongoing electrical expense and other operating expenses associated with maintaining such Tower lighting. If the increase in Tower height at the request of T-Mobile Collocator results in a requirement to detune the Tower, T-Mobile Collocator shall pay the cost of the related detuning equipment and its installation. If T-Mobile Collocator desires to replace or reinforce a Tower and requests that Tower Operator perform such work, Tower Operator shall or shall cause such work to be performed, and T-Mobile Collocator shall pay the actual, customary and reasonable one-time cost of such work (as a T-Mobile Collocator capital expenditure, without any increase in the T-Mobile Collocation Rent or payment of any fee or charge to Tower Operator), together with all actual, customary and reasonable costs incident thereto and a mutually acceptable construction management fee, within 30 days after Tower Operator delivers to T-Mobile Collocator a written invoice and reasonable supporting documentation for the cost of such work.

(b)Right of Substitution. (i) Notwithstanding anything to the contrary contained in this Agreement, within 15 Business Days after request by T-Mobile Collocator, Tower Operator shall notify T-Mobile Collocator whether there is any Available Space in respect of any Site. If any such Available Space then exists, T-Mobile Collocator shall have the one-time Right of Substitution as to such Available Space upon completing Tower Operator's standard application and amendment procedures, as described in Section 9(e), and obtaining the prior written consent of Tower Operator, which consent shall not be unreasonably withheld, conditioned or delayed; provided that Tower Operator shall be entitled to perform, in its reasonable discretion, a structural analysis, at T-Mobile Collocator's sole cost and expense, prior to consenting to such Right of Substitution. For the avoidance of doubt, T-Mobile Collocator may only exercise a Right of Substitution one time with respect to each Site.

(i)If T-Mobile Collocator elects to exercise its Right of Substitution, then, upon completion of the relocation of the Communications Equipment and Improvements of T-Mobile Collocator on

the Site (at T-Mobile Collocator's expense) the previously existing T-Mobile Collocation Space of the applicable Site shall automatically be released by T-Mobile Collocator and become a part of the Available Space of such Site and T-Mobile Collocator shall deliver such space in good condition, repair and order, reasonable wear and tear excepted, and shall remove all T-Mobile Communications Equipment therefrom and restore any damage thereto caused by, through or under any T-Mobile Group Member. Subject to the terms of this Agreement, and concurrently therewith, the Available Space on such Site to which the Communications Equipment and Improvements of T-Mobile Collocator have been relocated shall automatically become and constitute the T-Mobile Collocation Space.

(ii)The Parties shall promptly execute an amendment to the applicable Site Lease Agreement for the Site at which such Right of Substitution was exercised. T-Mobile Collocator shall, at its cost and expense, complete the relocation of its Communications Equipment.

(c)Additional Ground Space. If T-Mobile Collocator deems it necessary to obtain additional ground space (“Additional Ground Space”) to accommodate T-Mobile Collocator's needs at any Site, T-Mobile Collocator and Tower Operator shall cooperate to determine the availability of such space and negotiate the lease of such additional space if available on such Site or determine how to secure such space if it is not available on such Site and shall follow Tower Operator's standard application and amendment procedures as described in Section 9(e). If Tower Operator determines in its reasonable discretion that such Additional Ground Space is currently available at such Site, Tower Operator and T-Mobile Collocator shall enter into an amendment to the applicable Site Lease Agreement setting forth the terms under which T-Mobile Collocator shall lease any Additional Ground Space, which shall be negotiated by the Parties in good faith at the time T-Mobile Collocator deems it necessary to obtain such Additional Ground Space. Tower Operator shall be entitled to additional rent from T-Mobile Collocator if (i) the Additional Ground Space includes space outside of the ground space of the Site at the Effective Date or (ii) space in excess of the greater of (x) the Effective Date Ground Space and (y) 240 square feet of ground space.

(d)Required Ground Lessor and Governmental Consents. If the installation of any T-Mobile Communications Equipment, T-Mobile Improvement or any Tower Modification that T-Mobile Collocator desires to make requires the consent, approval, obtaining a zoning variance, or other action of a Ground Lessor, Governmental Authority or any other Person, as applicable, T-Mobile Collocator shall be responsible for obtaining the same at its sole cost and expense. If the installation of any Communications Equipment, Improvement or any Tower Modification that Tower Operator desires to make requires the consent, approval, obtaining a zoning variance, or other action of a Ground Lessor, Governmental Authority or any other Person, as applicable, Tower Operator shall be responsible for obtaining the same at its sole cost and expense or at the cost and expense of the applicable Tower Tenant.

SECTION 11.[Reserved].

SECTION 12.Limitations on Liens. T-Mobile Collocator shall not create or incur (and shall cause its Affiliates not to create or incur) any Lien (other than Permitted Encumbrances) against all or any part of any Site. If any such Lien (other than Permitted Encumbrances) is filed against all or any part of any Site as a result of the acts or omissions of T-Mobile Collocator or any of its Affiliates, T-Mobile Collocator shall cause the same to be promptly discharged by payment, satisfaction or posting of bond within 30 days after obtaining knowledge of such Lien. If T-Mobile

Collocator fails to cause any such Lien (other than Permitted Encumbrances) to be discharged within such 30-day period, Tower Operator shall have the right, but not the obligation, to cause such Lien to be discharged and may pay the amount of such Lien in order to do so. If Tower Operator makes any such payment, all amounts paid by Tower Operator shall be payable by T-Mobile Collocator to Tower Operator within 30 days after Tower Operator delivers a written invoice to T-Mobile Collocator for the same.

SECTION 13.Tower Operator Indemnity; T-Mobile Collocator 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 T-Mobile 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 by Tower Operator of its obligations and covenants under this Agreement;

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

(C) Tower Operator's use, operation, maintenance or occupancy of any part of a Non-Assignable Site in violation of the terms of any applicable Ground Lease; and

(D) 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;

provided, however, that notwithstanding the foregoing, Tower Operator will not be obliged to indemnify, defend and hold the T-Mobile 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 material respects and (2) no claims, demands, assessments, actions, suits, fines, levies or other penalties have been asserted against or imposed on T-Mobile Collocator 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)Tower Operator further agrees to indemnify, defend and hold each T-Mobile Indemnitee harmless under any other provision of this Agreement which expressly provides that Tower Operator shall indemnify, defend and hold harmless any T-Mobile Indemnitee with respect to the matters covered in such provision.

(b)T-Mobile Collocator Indemnity.

(i)Without limiting T-Mobile Collocator's other obligations under this Agreement, T-Mobile Collocator agrees 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) the acts or omissions of a T-Mobile Indemnitee or any of their respective engineers, contractors or subcontractors;

(C) any work at a Site performed at by or at the direction of a T-Mobile Indemnitee (but not including any work at any Site that Tower Operator is required to perform pursuant to this Agreement that T-Mobile Collocator elects to perform under Section 24);

(D) any T-Mobile Indemnitee's use, operation, maintenance or occupancy of any T-Mobile Communications Equipment or any portion of any Site (including the T-Mobile Collocation Space) in violation of the terms of this Agreement or any applicable Ground Lease; 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 T-Mobile Collocator or its agents, employees, engineers, contractors, subcontractors, licensees or invitees in connection with this Agreement.

(ii)T-Mobile Collocator further agrees to indemnify, defend and hold each Tower Operator Indemnitee harmless under any other provision of this Agreement which expressly provides that T-Mobile Collocator 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 13(a) or Section 13(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.

(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 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 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 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 13. If the Indemnifying Party does not notify the Indemnified party within such 30-day period that the Indemnifying Party disputes its liability to the Indemnified Party under Section 13(a) or Section 13(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 13(a) or Section 13(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 disputes the existence or scope of an obligation to indemnify for the Claim within such 30-day period, 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, at the Vice President level or higher, shall meet or confer by telephone within 20 Business Days in an attempt in good faith to resolve such dispute. If such Persons are unable to resolve the dispute, either Party may act to resolve the dispute in accordance with Sections 34(i) and 34(j).

(d)During the Term, for any dispute or litigation that arises during the Term in connection with any Ground Lessor, Ground Lease, Collocation Agreement, Tower Tenant or any other issue relating to the operation of the Sites (collectively, “Disputes”), Tower Operator shall have the right to control, prosecute, settle or compromise such Disputes; provided, however, that Tower Operator shall not settle or compromise such Disputes (i) for which Tower Operator is seeking a claim for indemnification under the Master Agreement or (ii) if the settlement or compromise involves an admission of any violation of Law or admission of wrongdoing by T-Mobile Collocator, in each case

without T-Mobile Collocator's consent which shall not be unreasonably withheld, conditioned or delayed.

SECTION 14.Waiver of Subrogation; Insurance.

(a)Mutual Waiver of Subrogation. To the fullest extent permitted by applicable Law, Tower Operator and T-Mobile Collocator each hereby waives any and all rights of recovery, claim, action or cause of action against the other and the other's Affiliates, for any loss or damage that occurs or is claimed to occur to its property at any Site, by reason of any cause insured against, or required to be insured against, by the waiving party under the terms of this Agreement, regardless of cause or origin. In addition, Tower Operator and T-Mobile Collocator shall each ensure that any property insurance policy it carries with respect to each Site shall provide that the insurer waives all rights of recovery, claim, action or cause of action by way of subrogation against any other Party with respect to Claims for damage to property covered by such policy.

(d)Insurance Premiums; Additional Insureds and Notice of Cancellation. Tower Operator and T-Mobile Collocator shall each pay all premiums for the insurance coverage which such Party is required to procure and maintain under this Agreement. Each insurance policy maintained by Tower Operator and T-Mobile Collocator (i) shall name the other Party as an additional insured if such insurance policy is for liability insurance (other than any workers' compensation policies) or a loss payee if such insurance policy is for casualty insurance; and (ii) shall provide that the policy cannot be canceled by the insurer as to the other Party except after the insurer gives the other Party 30 days' written notice of cancellation except for non-payment of premium. Regardless of the prior notice of cancellation required of the insurer(s), each party agrees to provide the other with at least 20 days' written notice of cancellation of any and all policies of insurance required by this Agreement. Tower Operator and T-Mobile Collocator shall deliver to the other a certificate or certificates of insurance evidencing the existence of all insurance with respect to each Site that such Party 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.

(e)Increased Policy Amounts. All policy amounts set forth in this Section 14 shall be evaluated by Tower Operator and increased (if Tower Operator deems necessary) every five years during the Term of this Agreement to such amounts as are customarily carried by prudent landlords and tenants in the telecommunications industry to insure risks associated with their respective interests in facilities comparable to the Sites. All policies of insurance required under this Section 14 shall be written on companies rated “A-VII” by AM Best or a comparable rating and licensed in the state where the applicable Site to which such insurance applies is located.

(f)Other Insurance. Tower Operator and T-Mobile Collocator each agrees that it shall not, on its own initiative or pursuant to the request or requirement of any Tower Tenant or other Person, take out separate insurance concurrent in form or contributing in the event of loss with that required to be carried by it pursuant to this Section 14, unless the other is named in the policy as

an additional insured or loss payee, if and to the extent applicable. Tower Operator and T-Mobile Collocator shall each immediately notify the other whenever any such separate insurance is taken out by it and shall deliver to the other original certificates evidencing such insurance.

SECTION 15.Estoppel Certificate. Tower Operator and T-Mobile Collocator each, from time to time upon 30 days' prior request by the other, shall execute, acknowledge and deliver to the other, or to a Person designated by the other, a certificate stating that this Agreement is unmodified and in full effect (or, if there have been modifications, that this Agreement is in full effect as modified, and setting forth such modifications) and the dates to which the T-Mobile Collocation Rent and other sums payable under this Agreement have been paid, and either stating that to the knowledge of the signer of such certificate no default exists under this Agreement or specifying each such default of which the signer has knowledge. The Party requesting such certificate shall, at its cost and expense, cause such certificate to be prepared for execution by the requested Party. Any such certificate may be relied upon by any prospective Mortgagee or purchaser of any portion of a Site.

T-Mobile Collocator shall pay to the applicable utility service provider the charges for all separately metered utility services used by T-Mobile Collocator at each Site in the operation of T-Mobile's Communications Facility at such Site. Notwithstanding the foregoing provisions of this Section 19, if the applicable utility service provider shall not render a separate xxxx for T-Mobile Collocator's usage, T-Mobile Collocator shall reimburse Tower Operator monthly for T-Mobile Collocator's actual metered usage at the rate charged to Tower Operator by the applicable utility service provider, or if Tower Operator is prohibited from installing a separate meter to measure T-Mobile Collocator's usage, T-Mobile Collocator may use Tower Operator's utility sources to provide utility service to the Communications Facility, and T-Mobile Collocator shall reimburse Tower Operator monthly for T-Mobile Collocator's actual usage at the rate charged to Tower Operator by the applicable service provider (and Tower Operator and T-Mobile Collocator agree to cooperate in determining a method by which to measure or estimate T-Mobile Collocator's usage if the usage is not capable of actual measurement). Notwithstanding anything to the contrary contained herein, Tower Operator shall have no obligation to provide, maintain or pay for utility services related to T-Mobile Communications Equipment. T-Mobile Collocator shall pay for all utility

services utilized by T-Mobile Collocator and its Affiliates in its operations at each Site prior to delinquency.

(b)If not prohibited by applicable Laws, T-Mobile Collocator shall allow Tower Operator to use T-Mobile Collocator's power sources at all Sites with tower lighting systems, solely for the purpose of providing electrical power for Tower Operator's light monitoring equipment on such Site and to maintain Tower lighting on such Site as required under this Agreement and applicable Law, and subject to the terms of the Transition Services Agreement. Connecting Tower Operator's light monitoring equipment to T-Mobile Collocator's electrical power source (unless necessary as a result of an increase in the height of a Tower due to a Modification made at the request of T-Mobile Collocator) shall be at Tower Operator's sole cost and expense. Notwithstanding the foregoing, at any Site where Tower Operator uses T-Mobile Collocator's power sources, Tower Operator may continue to use such T-Mobile Collocator power sources in consideration of a monthly payment of $50.00 for incandescent lighting or $20.00 for strobe and LED lighting. Tower Operator may connect to its own power source and stop using T-Mobile Collocator's power source at any time, upon which its obligation to make such monthly payments shall cease. Notwithstanding anything to the contrary contained herein, Tower Operator is not required to obtain its own power source for lighting and monitoring equipment if lighting at a Site is not required under applicable Law (including approvals granted by any local zoning board) or other existing written agreement.

(c)T-Mobile Collocator may sublease, license or sublicense all or any portion of the T-Mobile Collocation Space at any Site to any Backhaul Operator (as defined below) providing Backhaul Services (as defined below) exclusively to T-Mobile Collocator in connection with the operation of T-Mobile Collocator's communications network and allow such Backhaul Operator to use its network, T-Mobile Communications Equipment, T-Mobile Improvements or Communications Facility; provided, however, that (i) T-Mobile Collocator shall follow the application and amendment requirements set forth in Section 9(e) with respect to such sublease, license or sublicense and (ii) substantially concurrently with and as a condition precedent to such sublease, license or sublicense T-Mobile Collocator shall enter into a three-party agreement with Tower Operator and such Backhaul Operator, which agreement shall, among other things, provide that if at any time such Backhaul Operator provides Backhaul Services to any Tower Tenant, then such Backhaul Operator shall pay rent to Tower Operator for the space occupied by its equipment at fair market rates (to be further described in such three-party agreement). “Backhaul Operator” means a Person providing services to transmit voice, video, internet or data from a Site to another location. “Backhaul Services” means, with respect to a Site, the transmission of voice, video, internet or data originating from T-Mobile Collocator or a Tower Tenant Communications Equipment base station appurtenant to such Site.

SECTION 20.Compliance with Law; Governmental Permits.

(a)Tower Operator shall, at its own cost and expense, obtain and maintain in effect all certificates, permits, licenses and other approvals relating to Government Approvals (including those relating to FCC and FAA regulations) and comply with all Laws, required or imposed by Governmental Authorities, in connection with the operation and maintenance of the Included Property at each Site (including the Tower on such Site). Tower Operator shall conduct annual inspections of all Sites; provided that until the requisite waiver from the FCC has been obtained by the T-Mobile Ground Lease Additional Party with respect to the Non-Assignable Sites, Tower Operator shall conduct quarterly inspections of all Non-Assignable Sites with lighted Towers of such T-Mobile Ground Lease Additional Party. T-Mobile Collocator shall, at its own cost and expense,

comply with all Laws, required or imposed by Governmental Authorities, in connection with its use of each Site.

(b)Tower Operator shall, at its own cost and expense, reasonably cooperate with T-Mobile Collocator or its Affiliates in their efforts to obtain and maintain in effect any certificates, permits, licenses and other approvals and to comply with any Laws required or imposed on T-Mobile Collocator by Governmental Authorities applicable to the T-Mobile Communications Equipment and the T-Mobile Collocation Space. Without limiting the generality of the immediately preceding sentence, Tower Operator shall, at its own cost and expense, provide to T-Mobile Collocator any documentation that may be necessary for T-Mobile Collocator to comply with all FCC reporting requirements relating to the T-Mobile Communications Equipment and the T-Mobile Collocation Space.

(c) Notwithstanding anything herein to the contrary, Tower Operator shall have no obligation to provide any information necessary for T-Mobile Collocator to obtain any certificate, permit or other approval relating to the T-Mobile Communications Equipment itself (e.g., FCC type certification).

(d) T-Mobile Collocator shall reasonably cooperate with Tower Operator in Tower Operator's efforts to provide required information and to comply with all Laws required or imposed by Governmental Authorities applicable to each Site.

SECTION 21.Compliance with Specific FCC Regulations.

(a)From and after the Effective Date, T-Mobile Collocator shall cooperate (and cause its Affiliates to cooperate) with each Tower Tenant with respect to each Site regarding compliance with applicable FCC regulations.

(b)T-Mobile Collocator acknowledges and agrees that T-Mobile Communications Equipment at each Site is subject to the regulations of the FCC, including regulations regarding exposure by workers and members of the public to the radio frequency emissions generated by T-Mobile Communications Equipment, and T-Mobile Collocator agrees to comply (and T-Mobile Collocator shall cause its Affiliates to comply) with all FCC Regulations and all other Applicable Laws. T-Mobile Collocator acknowledges that such regulations prescribe the permissible exposure levels to emissions from its Communications Equipment, which can generally be met by maintaining safe distances from such Communications Equipment. T-Mobile Collocator shall install at its expense such marking, signage, or barriers to restrict access to any T-Mobile Communications Equipment on a Site in respect of any T-Mobile Collocation Space on such Site as T-Mobile Collocator deems necessary in order to comply with the applicable FCC regulations. T-Mobile Collocator shall cooperate in good faith with Tower Operator to minimize any confusion or unnecessary duplication that could result in similar signage being posted with respect to any T-Mobile Communications Equipment at or near any Site in respect of any T-Mobile Collocation Space on such Site. T-Mobile Collocator, at its option, may also install signage at any Site identifying T-Mobile's Communications Facility at such Site and providing for contact information in the case of an Emergency.

(c)T-Mobile Collocator further agrees to alert all personnel working at or near each Site, including T-Mobile Collocator's maintenance and inspection personnel, to maintain the prescribed

distance from the Communications Equipment and to otherwise follow the posted instructions of Tower Operator.

(d)The Parties acknowledge that T-Mobile Collocator (or an Affiliate thereof) is licensed by the FCC to provide telecommunications 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 T-Mobile Collocator (or an Affiliate thereof) to Tower Operator with respect to telecommunications services provided by T-Mobile Collocator or its Affiliates, to allow Tower Operator to in any manner control the T-Mobile Communications Equipment, or to limit the right of T-Mobile 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 T-Mobile Collocator or its Affiliates may take with respect to a Site).

SECTION 22.Holding Over. If during the Term of this Agreement T-Mobile Collocator remains in possession of the T-Mobile Collocation Space at any Site after expiration or termination of T-Mobile Collocator's leaseback of or other right to use and occupy the T-Mobile Collocation Space at such Site without any express written agreement by Tower Operator, then T-Mobile Collocator shall be a month-to-month tenant with the monthly T-Mobile Collocation Rent equal to 150% of the monthly T-Mobile Collocation Rent last applicable to the T-Mobile Collocation Space and subject to all of the other terms set forth in this Agreement. If T-Mobile Collocator remains a month-to-month holdover tenant at any Site for more than 12 consecutive months, T-Mobile Collocator shall be deemed to have renewed its leaseback or other right to use and occupy the T-Mobile Collocation Space at such Site for a renewal term of five years, with the monthly T-Mobile Collocation Rent being equal to the monthly T-Mobile Collocation Rent applicable during the period of such month-to-month tenancy (provided such rent shall not be less than the fair market rent of such Site at that time) and subject to all of the other terms set forth in this Agreement (including with respect to any escalation of such T-Mobile Collocation Rent by reference to CPI or any other increases in or adjustments to such T-Mobile Collocation Rent).

SECTION 23.Rights of Entry and Inspection. T-Mobile Collocator shall permit Tower Operator and Tower Operator's representatives to conduct visual inspections of T-Mobile Communications Equipment located on the Tower in accordance with the general standard of care in the tower industry to ascertain compliance with the provisions of this Agreement. Tower Operator may visually inspect, but shall not be entitled to have any access to any enclosed T-Mobile Communications Equipment. Nothing in this Section 23 shall imply or impose any duty or obligation upon Tower Operator to enter upon any Site at any time for any purpose, or to inspect T-Mobile Communications Equipment at any time, or to perform, or pay the cost of, any work that T-Mobile Collocator or its Affiliates is required to perform under any provision of this Agreement, and Tower Operator has no such duty or obligation.

SECTION 24.Right to Act for Tower Operator. In addition to and not in limitation of any other remedy T-Mobile Collocator 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 have a material adverse effect on the ability of T-Mobile Collocator to operate the T-Mobile Communications Equipment at any Site, then subject to the following sentence, T-Mobile Collocator 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 (except any work on the tower), 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, T-Mobile Collocator shall give Tower Operator at least 10 Business Days' prior written notice of T-Mobile Collocator's intended action and Tower Operator 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 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 T-Mobile Collocator may take include, in addition to any actions permitted under Section 4, the payment of insurance premiums that Tower Operator is required to pay under this Agreement and the payment of Ground Rent that Tower Operator is required to pay under the Ground Leases. T-Mobile Collocator may pay all incidental costs and expenses incurred in exercising its rights under this Agreement, 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 T-Mobile Collocator in accordance with this Section 24 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.

(ii)A Bankruptcy event occurs with respect to Tower Operator; or Tower Operator becomes insolvent or makes an assignment for the benefit of creditors; or any action is brought by Tower Operator seeking its dissolution or liquidation of its assets or seeking the appointment of a trustee, interim trustee, receiver or other custodian for any of its property; or Tower Operator commences a voluntary proceeding under the federal Bankruptcy Code; or any action or petition is otherwise brought by Tower Operator seeking similar relief or alleging that it is insolvent or unable to pay its debts as they mature; or any action is brought against Tower Operator seeking its dissolution or liquidation of any of its assets, or seeking the appointment of a trustee, interim trustee, receiver or other custodian for any of its property, and any such action is consented to or acquiesced in by Tower Operator or is not dismissed within 90 days after the date upon which it was instituted; or any Bankruptcy proceeding is instituted against Tower Operator and (A) an Order for relief is entered in such proceeding, or (B) such proceeding is consented to or acquiesced in by Tower Operator or is not dismissed within 90 days after the date upon which it was instituted; or any action or petition is otherwise brought against Tower Operator seeking similar relief or alleging that it is insolvent, unable to pay its debts as they mature or generally not paying its debts as they become due, and such action or petition is consented to or acquiesced in by Tower Operator or is not dismissed within 90 days after the date upon which it was brought; or

(iii)The leaseback to T-Mobile Collocator or other right by T-Mobile Collocator to use and occupy the T-Mobile Collocation Space is rejected by Tower Operator under Section 365 of the federal Bankruptcy Code.

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 as a result of the occurrence of any Force Majeure, (ii) 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 T-Mobile Collocator 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 and (iii) Section 5(a), Section 6, Section 8(a), Section 8(c), Section 17, Section 20 or Section 21 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 T-Mobile Collocator 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 6(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 occurrence is deemed an emergency, a priority or a routine matter in accordance with Tower Operator's then current practices).

(d)T-Mobile Collocator Remedies.

(i)Upon the occurrence of any event of default by Tower Operator under Section 25(c)(i) in respect of any Site, T-Mobile Collocator 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 25(c)(ii) or Section 25(c)(iii), T-Mobile Collocator may terminate this Agreement as to such Site 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)Upon the occurrence of events of default by Tower Operator (excluding those resulting from any default of T-Mobile Collocator or the occurrence of any Force Majeure) not cured as provided for in Section 25(c) by Tower Operator relating to more than 20% of the Sites, in the aggregate, during any consecutive five-year period, so that the aggregate impact of those uncured defaults results in material harm to the business and operations of T-Mobile Collocator and subject to arbitration under Section 25(f), T-Mobile Collocator may, upon giving 60 days' prior written notice to Tower Operator, terminate this Agreement as to all Sites (which notice shall contain a reasonably specific description of each of such events of default), and this Agreement shall be terminated as to all Sites at the time designated by T-Mobile Collocator in its notice of termination to Tower Operator.

(iv)Notwithstanding anything to the contrary contained herein, if Tower Operator is determined to be in default pursuant to Section 25(f), 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)No Limitation on Remedies. T-Mobile Collocator 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 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, T-Mobile Collocator may perform, on behalf of Tower Operator, Tower Operator's obligations under the terms of this Agreement pursuant to Section 24.

(f)Arbitration. Notwithstanding anything in this Agreement to the contrary, any Party receiving notice of a default or termination under this Agreement may, within 10 days after receiving the notice, initiate arbitration proceedings to determine the existence of any such default or

termination right. Such arbitration proceedings shall be conducted in accordance with and subject to the procedures for arbitration set forth in the Master Agreement.

(g)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.

(h)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 25, or partial termination of a Party's rights hereunder, shall not terminate or diminish any Parties' rights with respect to the obligations that were to be performed on or before the date of such termination.

(i)Continuing Obligations. Any termination by Tower Operator of T-Mobile Collocator's rights with respect to any or all Sites pursuant to Section 25(b) shall not diminish or limit any obligation of T-Mobile Collocator to pay the T-Mobile Collocation Rent provided for herein or any other amounts with respect to such Site(s).

SECTION 26.Quiet Enjoyment. Tower Operator covenants that T-Mobile Collocator shall, subject to the terms and conditions of this Agreement, peaceably and quietly hold and enjoy the T-Mobile Collocation Space at each Site and shall have the right provided herein to operate its equipment at each Site without hindrance or interruption from Tower Operator.

SECTION 27.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 27, 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 28.Broker and Commission.

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

(b)Tower Operator and T-Mobile Collocator 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 T-Mobile Parent.

SECTION 29.Recording of Memorandum of Site Lease Agreement; Preparation and Amendment to the Site Lease Agreement.

(a)Subject to the applicable provisions of the Master Agreement, for each T-Mobile Collocation Space at an Assignable Site, following the execution of this Agreement or after any Conversion Closing, T-Mobile Collocator 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 property records (unless the Ground Lease for any applicable Assignable 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)The Parties shall cooperate with each other to cause changes to be made in the Memorandum of Site Lease Agreement for such Site, if such changes are requested by either Party to evidence any permitted changes in the description of the T-Mobile Collocation Space respecting such Site or equipment or improvements thereof, and the Party that requested such changes to the Memorandum of Site Lease Agreement shall record same at its sole cost and expense and shall promptly provide in electronic form a recorded copy of same to the other Party.

SECTION 30.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 T-Mobile Collocator in writing as to whether 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 the Casualty Notice states that such Site is a Non-Restorable Site, then Tower Operator or T-Mobile Collocator shall have the right to terminate

T-Mobile Collocator's leaseback or other use and occupancy of the T-Mobile Collocation Space at such Site, upon written notice to the other Party (given within the time period required below) and such leaseback or other use and occupancy at such Site shall terminate as of the date of such notice. 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 such Site but Tower Operator determines that the Site is a Restorable 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 30.

(c)Without limiting Tower Operator's obligations under this Agreement in respect of a Site subject to a casualty, if Tower Operator undertakes the Restoration of a Site that has suffered a casualty, Tower Operator shall, if commercially feasible, make available to T-Mobile Collocator a portion of the Included Property of such Site for the purpose of T-Mobile Collocator locating, at its sole cost and expense, a temporary communications facility, and shall give T-Mobile Collocator priority over Tower Tenants at such Site as to the use of such portion of the Site; provided, however, that (i) the placement of such temporary communications facility shall not interfere in any material respect with Tower Operator's Restoration or the continued operations of any Tower Tenant; (ii) T-Mobile Collocator shall obtain any permits and approvals, at T-Mobile Collocator's cost, required for the location of such temporary communications facility on such Site; and (iii) there must be Available Space on the Site for locating such temporary communications facility.

(d)If Tower Operator undertakes the Restoration of a Site but fails at any time to diligently pursue the substantial completion of the Restoration (subject to delay for Force Majeure or the inability to obtain Governmental Approvals, as opposed to merely a delay in obtaining Governmental Approvals), T-Mobile Collocator may terminate this Agreement as to T-Mobile Collocator's leaseback or other use and occupancy of the T-Mobile Collocation Space at such Site upon giving Tower Operator written notice of its election to terminate at any time prior to completion of the Restoration.

(e)From and after any casualty as to any Site described in this Section 30 and during the period of Restoration at a Site, the T-Mobile Collocation Rent with respect to such Site shall xxxxx until completion of the Restoration.

(f)The Parties acknowledge and agree that this Section 30 is in lieu of and supersedes any statutory requirements under the laws of any State applicable to the matters set forth in this Section 30.

SECTION 31.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 T-Mobile Collocator shall have the right to terminate this Agreement as to such Site by providing written notice to 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; provided, however, that T-Mobile Collocator shall be entitled to prosecute and claim an amount of any Award reflecting its interest under this Agreement. 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 for the remainder of the Term 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 an Assignable Site, or unable to operate such Site, if a Non-Assignable 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 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.

(d)If there occurs a Taking of all or any part of any T-Mobile Collocation Space at any Site for temporary use, then this Agreement shall remain in full force and effect as to such Site for the remainder of the then-current Term. Notwithstanding anything to the contrary contained in this Agreement, during such time as T-Mobile Collocator shall be out of possession of such T-Mobile Collocation Space by reason of such Taking, the failure by T-Mobile Collocator to keep, observe, perform, satisfy, and comply with these terms and conditions of this Agreement compliance with which are effectively impractical or impossible as a result of T-Mobile Collocator's being out of possession of such T-Mobile Collocation Space shall not be a breach of or an event of default under this Agreement, and T-Mobile Collocator shall not be liable for payment of the T-Mobile Collocation Rent during the period of the temporary Taking.

SECTION 32.[Reserved].

SECTION 33.CA/NV Purchase Option. Tower Operator shall notify T-Mobile Collocator as to whether or not Tower Operator shall exercise any then applicable and existing purchase option under the CA/NV Master Lease with respect to any CA/NV Site no later than 180 days prior to the expiration of the Option Trigger Window (as defined in the CA/NV Master Lease) with respect to such CA/NV Site. If such notice states that Tower Operator shall exercise such option, such notice shall state the date on which Tower Operator shall exercise such option. If (i) such notice states

that Tower Operator shall not exercise such option and (ii) Tower Operator has not otherwise secured the tenure of such CA/NV Site and shall forfeit such CA/NV Site if Tower Operator does not exercise such option, then:

(a)Tower Operator shall take commercially reasonable efforts to assign Tower Operator's rights to such purchase option (and the related obligations under the CA/NV Master Lease) to T-Mobile Collocator;

(b)T-Mobile Collocator shall pay to SBC Tower Holdings LLC or its successor under the CA/NV Master Lease the purchase price with respect to such exercise of such option; and

(c)Tower Operator shall have no further rights or obligations pursuant to this Agreement or otherwise with respect to the CA/NV Sites subject to such purchase option.

If the CA/NV Master Lease expires with respect to any CA/NV Site before this Agreement expires with respect to such CA/NV Site, including as a result of the failure to exercise any then applicable and existing purchase option for such CA/NV Site, then this Agreement shall terminate and have no further force and effect as to the T-Mobile Collocation Space within such CA/NV Site (except for any obligations accruing prior to or as of the expiration date for such Site that are then unperformed).

Notwithstanding the foregoing, Tower Operator shall not be required to give the notice referred to in the first paragraph of this Section 33 and T-Mobile Collocator shall have no rights under this Section 33 (A) if T-Mobile Collocator is in default of its obligations under this Agreement as to the applicable CA/NV Site beyond applicable notice and cure periods provided herein, (B) if T-Mobile Collocator has given a Termination Notice relating to such CA/NV Site or (C) Tower Operator has otherwise secured the tenure of such CA/NV Site and shall not forfeit such CA/NV Site if Tower Operator does not exercise such option.

(f)Amendment; Modifications. This Agreement may be amended, modified or supplemented only by written agreement of the Parties.

(g)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.

(h)Specific Performance. Each Party recognizes and agrees that in the event of any failure or refusal to perform the obligations required by this Agreement, remedies at Law would be inadequate and that, subject to the terms of this Agreement, in addition to such other remedies as may be available to it at Law or in equity, either party may seek injunctive relief and to enforce its rights by an action for specific performance to the fullest extent permitted by applicable Law. 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 34(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 of this Agreement or applicable Law for such breach or threatened breach, including the recovery of damages.

(i)Jurisdiction and Consent to Service. Each of the Parties (i) agrees that any suit, action or proceeding arising out of or relating to this Agreement shall be brought solely in the state courts of the State of New York sitting in the County of New York or federal courts of the State of New York for the Southern District of New York, and appellate courts having jurisdiction of appeals from any of the foregoing, (ii) consents to the exclusive jurisdiction of each such court in any suit, action or proceeding relating to or arising out of this Agreement, (iii) waives any objection that it may have to the laying of venue in any such suit, action or proceeding in any such court, and (iv)

agrees that service of any court paper may be made in such manner as may be provided under applicable Laws or court rules governing service of process.

(j)WAIVER OF JURY TRIAL. EACH PARTY TO THIS AGREEMENT WAIVES ITS RIGHT TO A JURY TRIAL IN ANY COURT ACTION ARISING AMONG ANY OF THE PARTIES HEREUNDER, WHETHER UNDER OR RELATING TO THIS AGREEMENT, AND WHETHER MADE BY CLAIM, COUNTER CLAIM, THIRD PARTY CLAIM OR OTHERWISE.

(k)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. It is understood and agreed that T-Mobile Collocator or an Affiliate of T-Mobile Collocator will be entering into a particular Site Lease Agreement and that each such Affiliate executing the applicable Site Lease Agreement shall be liable with respect to such Site Lease Agreement (for the avoidance of doubt, Section 35 will remain unaffected and in full force and effect). All communications and invoices relating to a Site Lease Agreement must be directed to the party signing that Site Lease Agreement.

(l)Severability. If any term or provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nonetheless remain in full force and effect so long as the economic and legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

(m)Conversion of MPL Sites. Notwithstanding anything to the contrary in this Agreement, all “Sites” with respect to which the “Tower Operator” under the Master Prepaid Lease exercises its “Purchase Option” under the Master Prepaid Lease shall automatically become subject to and Sites under and governed by this Agreement as of the applicable “Purchase Option Closing Date” specified in the Master Prepaid Lease. The Parties shall enter into appropriate documentation to evidence the same.

SECTION 35.T-Mobile Parent Guarantee.

(a)T-Mobile Parent unconditionally guarantees to the Tower Operator Indemnitees the full and timely payment of all obligations of T-Mobile Collocator under Section 4 of this Agreement and any corresponding obligations of T-Mobile Collocator or any Affiliate of T-Mobile Collocator under any Site Lease Agreement (collectively, the “T-Mobile Collocator Obligations”). T-Mobile Parent agrees that if T-Mobile Collocator (all references to T-Mobile Collocator in this Section 35 shall be deemed to include any Affiliate of T-Mobile Collocator that is a party to any Site Lease Agreement) defaults at any time during the Term of this Agreement or the term of any Site Lease Agreement in the performance of any of the T-Mobile Collocator Obligations, T-Mobile Parent shall faithfully perform and fulfill all T-Mobile Collocator 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 T-Mobile Collocator and on account of the enforcement of this guaranty.

(b)The foregoing guaranty obligation of T-Mobile Parent shall be enforceable by any Tower Operator Indemnitee in an action against T-Mobile Parent without the necessity of any suit, action or proceeding by the applicable beneficiary of any kind or nature whatsoever against T-Mobile Collocator, without the necessity of any notice to T-Mobile Parent of T-Mobile Collocator's default or breach under this Agreement or any Site Lease Agreement, and without the necessity of any other notice or demand to T-Mobile Parent to which T-Mobile Parent might otherwise be entitled, all of which notices T-Mobile Parent hereby expressly waives. T-Mobile Parent hereby agrees that the validity of this guaranty and the obligations of T-Mobile Parent 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 T-Mobile Collocator any of the rights or remedies reserved to such Tower Operator Indemnitee pursuant to the provisions of this Agreement, any Site Lease Agreement or any other remedy or right which such Tower Operator Indemnitee may have at law or in equity or otherwise.

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

(d)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. T-Mobile Parent hereby waives presentment demand for performance, notice of nonperformance, protest notice of protest, notice of dishonor and notice of acceptance. T-Mobile Parent further waives any right to require that an action be brought against T-Mobile Collocator or any other Person or to require that resort be had by a beneficiary to any security held by such beneficiary.
