In the event that the CA/NV Inclusion shall not have occurred at the Initial Closing, T-Mobile or Crown may, at any time from and after the Initial Closing Date and prior to the date that is 10 business days prior to the CA/NV Final Date, initiate a closing with respect to the CA/NV Sites (the “ CA/NV Subsequent Closing ”), so long as the initiating Party has provided the other Parties with at least 10 business days’ notice prior to the date on which the CA/NV Subsequent Closing shall be held (the “ CA/NV Subsequent Closing Date ”); provided that (i) all applicable conditions set forth in Article 10 (other than Section 10.4 and Section 10.5 ) have been satisfied or (to the extent permitted under applicable Law) waived on or prior to the CA/NV Subsequent Closing Date (all references in Article 10 and in any related provisions to the Initial Closing Date shall be deemed to refer to the CA/NV Subsequent Closing Date), (ii) if T-Mobile is the initiating Party, Crown shall have received, on or prior to the day that is 10 business days prior to the CA/NV Subsequent Closing Date, the CA/NV Consent and Acknowledgment, and (iii) if T-Mobile is the initiating Party, the inclusion of the CA/NV Sites in the transactions consummated on the Initial Closing Date would not have resulted in the failure of either the Minimum Lease Site and Assignable Site Closing Condition or the Minimum Contributable Site and Assignable Site Closing Condition as of the Initial Closing Date (based on the Site Designation of each of the CA/NV Sites as of the CA/NV Subsequent Closing Date); provided further that in no event shall the CA/NV Subsequent Closing be held on a day that is not a business day or on a date that is after the CA/NV Final Date unless and to the extent that Crown has breached any of its obligations under this Agreement that result in a substantial delay to, or preventing, the occurrence of the CA/NV Subsequent Closing prior to the CA/NV Final Date. On the CA/NV Subsequent Closing Date, the Parties shall execute and deliver, if and to the extent applicable, (i) amended schedules and exhibits to the Sale Site MLA, (ii) amended schedules and exhibits to the Management Agreement, (iii) with respect to each CA/NV Site that is an Assignable Site, the documentation necessary to sell, convey, assign, transfer and deliver to the applicable Sale Site Subsidiary (or its designee) all rights of the T-Mobile Contributors and their Affiliates under the CA/NV Master Lease and all other CA/NV Site Agreements, CA/NV Ground Leases and related Collocation Agreements related to such CA/NV Site, and all their right, title and interest in, to and under such CA/NV Site and the Included Property of such CA/NV Site and (iv) amended schedules or exhibits to all other applicable Collateral Agreements. At the CA/NV Subsequent Closing, (x) if the Subsequent Closing Total CA/NV Consideration is a positive number, Crown shall pay (by wire transfer as directed in writing by T-Mobile), to the applicable T-Mobile Party the Subsequent Closing Total CA/NV Consideration less any Tower Operator Reimbursable Expenses related to the CA/NV Sites, and (y) if the Subsequent Closing Total CA/NV Consideration is a negative number, T-Mobile shall pay (by wire transfer as directed in writing by Crown), to Crown (or its designee) the absolute value of the Subsequent Closing Total CA/NV Consideration together with any Tower Operator Reimbursable Expenses related to the CA/NV Sites. Upon the occurrence of, and after giving effect to the CA/NV Subsequent Closing, the Initial Closing and the CA/NV Subsequent Closing shall be treated as a single closing hereunder, and the transactions consummated pursuant to the Initial Closing and the CA/NV Subsequent Closing shall be treated as a single, integrated and indivisible transaction for all purposes of this Agreement. In the event that the CA/NV Consent and Acknowledgement shall not have been obtained by the date that is 10 business days prior to the CA/NV Final Date, Crown may elect, in its sole discretion, to exclude the CA/NV Sites from the transactions contemplated by this Agreement, in which case all CA/NV Sites shall be designated and treated as Excluded Sites for all purposes of this Agreement.

(c) Conversion Closings . The conversion of a Non-Contributable Site to a Contributable Site, a Pre-Lease Site into a Lease Site or a Non-Assignable Site into an Assignable Site subsequent to the Applicable Closing Date (each a “ Conversion Closing ”) shall occur automatically following the satisfaction or cure of all of the Contribution Exceptions, Leasing Exceptions or Assignment Exceptions, as applicable, with respect to such Sites. For purposes of clarification, a Non-Contributable Site which is converted to a Contributable Site, but for which there are remaining unsatisfied Leasing Exceptions, shall remain a Pre-Lease Site until such Leasing Exceptions are satisfied or cured. In addition, as provided in Section 2.7 , the Parties shall hold a closing (each a “ Technical Closing ”) to confirm the occurrence of a Conversion Closing with respect to each applicable Non-Contributable Site, Pre-Lease Site or Non-Assignable Site, as the case may be. In addition, for purposes of clarification, subject to the terms and conditions of this Agreement, Sale Sites shall be subject to the Sale Site MLA and MPL Sites shall be subject to the MPL Site MLA.

For completeness and administrative convenience, the Settlement Firm Site Report shall also incorporate all items from the Crown Site Report that have become final and binding pursuant to Section 3.3(b) and all items reflected in the certificate delivered pursuant to Section 3.3(b) . Judgment may be entered upon the Settlement Firm Site Report in any court having jurisdiction over the Party against which such report is to be enforced.

SECTION 3.4 Payment of Final Total Consideration .

(a) On the business day following the determination of the Final Total TCF and Final Site Designation for all Portfolio Sites (the “ Final Payment Date ”), if (i) the sum of (x) the Closing Total Consideration plus (y) the Subsequent Closing Total CA/NV Consideration, if any, plus (z) the Aggregate Deferred Managed Site Consideration, in each case calculated based on the Site Designation set forth in the Updated Site List, less (ii) any refunds received by Crown pursuant to Section 4.8 or Section 4.9 plus (iii) any payments made by Crown pursuant to Section 4.8 or Section 4.9 less (iv) any Excluded Site Collocation Payments paid to or received by Crown, the Tower Operator or any Sale Site Subsidiary following the Initial Closing and on or prior to such date exceeds the sum of (1) the Final Total Consideration plus (2) the Aggregate Deferred Managed Site Consideration (calculated based on the assumption that the Deferred Managed Site Consideration for each Managed Site was based on the Final Total TCF for such Managed Site), in each case calculated based on the Final Site Designation and taking into account any Site re-designations pursuant to Section 4.8 and Section 4.9 , then the T-Mobile Parties and the T-Mobile SPEs shall be obligated to pay Crown cash in an amount equal to such excess, together with interest thereon at a rate equal to 6% per annum (the “ Interest Rate ”), calculated on the basis of the actual number of days elapsed divided by 360, from the Initial Closing Date to the date of payment.

(b) On the Final Payment Date, if the sum of (1) the Final Total Consideration plus (2) the Aggregate Deferred Managed Site Consideration (calculated based on the assumption that the Deferred Managed Site Consideration for each Managed Site was based on the Final Total TCF for such Managed Site), in each case calculated based on the Final Site Designation and taking into account any Site re-designations pursuant to Section 4.8 and Section 4.9 , exceeds (i) the sum of (x) the Closing Total Consideration plus (y) the Subsequent Closing Total CA/NV Consideration, if any, plus (z) the Aggregate Deferred Managed Site Consideration, in each case calculated based on the Site Designation as set forth in the Updated Site List, less (ii) any refunds received by Crown pursuant to Section 4.8 and Section 4.9 plus (iii) any payments made by Crown pursuant to Section 4.8 and Section 4.9 less (iv) any Excluded Site Collocation Payments paid to or received by Crown, the Tower Operator or any Sale Site Subsidiary following the Initial Closing and on or prior to such date, then Crown shall be obligated to pay the T-Mobile SPEs or the T-Mobile Parties, as applicable, cash in an amount equal to such excess, together with interest thereon at the Interest Rate, calculated on the basis of the actual number of days elapsed divided by 360, from the Initial Closing Date to the date of payment.

(c) On the Final Payment Date, in the event that, based on the Final Site Designation of each of the Portfolio Sites (and, for purposes of the definitions of Minimum Lease Site and Assignable Site Closing Condition, Target Contributable Site and Assignable Site TCF, Minimum Contributable Site and Assignable Site Closing Condition and Target Lease Site and Assignable Site TCF, based on the Final Total TCF for each Portfolio Site):

(i) the Minimum Lease Site and Assignable Site Closing Condition would not have been satisfied as of the Initial Closing Date under either or both of Section 10.4 or Section 2.6(b)(iii) , the T-Mobile Parties and the T-Mobile SPEs shall be obligated to pay Crown cash in an amount equal to 50% of the product of (x) the TCF Multiple multiplied by (y) the difference of (A) 80% of the aggregate Final Total TCF for all Portfolio Sites as set forth in the Settlement Firm Site Report and (B) the aggregate Final Total TCF for all Lease Sites and Assignable Sites as set forth in the Settlement Firm Site Report, together with interest thereon at the Interest Rate, calculated on the basis of the actual number of days elapsed divided by 360, from the Initial Closing Date to the date of payment;

(ii) the Minimum Contributable Site and Assignable Site Closing Condition would not have been satisfied on the Initial Closing Date under either or both of Section 10.4 or Section 2.6(b)(iii) , the T-Mobile Parties and the T-Mobile SPEs shall be obligated to pay Crown cash in an amount equal to 50% of the product of (x) the TCF Multiple multiplied by (y) the difference of (A) 95% of the aggregate Final Total TCF for all Portfolio Sites as set forth in the Settlement Firm Site Report and (B) the Final Total TCF for all Contributable Sites and Assignable Sites as set forth in the Settlement Firm Site Report, together with interest thereon at the Interest Rate, calculated on the basis of the actual number of days elapsed divided by 360, from the Initial Closing Date to the date of payment; or

(iii) both the Minimum Lease Site and Assignable Site Closing Condition and the Minimum Contributable Site and Assignable Site Closing Condition would not have been satisfied on the Initial Closing Date under either or both of Section 10.4 or Section 2.6(b)(iii) , the T-Mobile Parties and the T-Mobile SPEs shall be obligated to pay Crown cash in an amount equal to the greater of the amounts specified in clauses (i) and (ii) above;

provided , however , (x) that if the CA/NV Inclusion occurs but the CA/NV Closing Condition was not satisfied at the time of such occurrence, the TCF and Supplemental TCF of all CA/NV Sites shall be excluded for purposes of all calculations under this Section 3.4(c) (for the avoidance of doubt, if Crown waives the CA/NV Closing Condition, the amount set forth in this Section 3.4(c) shall be calculated as if such CA/NV Sites were not included in this transaction) and (y) in no event shall the amount payable by the T-Mobile Parties and the T-Mobile SPEs to Crown under this Section 3.4(c) exceed $200,000,000 in the aggregate.

(d) On the second business day following the Final Payment Date (i) the Parties shall calculate the net amount owed to Crown or to the T-Mobile Parties and the T-Mobile SPEs, as the case may be, pursuant to this Section 3.4 and (ii) the Party that is obligated to pay such net amount shall make a single payment in immediately available funds by wire transfer to an account designated in writing by the Party to which such payment is owed.

SECTION 3.5 Further Assurances .

(a) The T-Mobile Parties and the T-Mobile SPEs shall take all actions and execute all documents reasonably necessary to ensure that, in the event a Portfolio Site was incorrectly designated on the Updated Site List, Crown, the Tower Operator and, after the Initial Closing, the applicable Sale Site Subsidiary are put in the same legal and economic position as they would have been in had such Portfolio Site been correctly designated on the Updated Site List, including, in the event any Site has been re-designated as an Excluded Site from its original Site Designation on the Updated Site List, to rescind the transaction that occurred with respect to such Site at the applicable Closing under this Agreement and the Collateral Agreements. In furtherance of the foregoing, the Parties shall execute and deliver, as applicable, (i) amended schedules and exhibits to the MPL, (ii) amended schedules and exhibits to the applicable MLA, (iii) amended schedules and exhibits to the Management Agreement, (iv) the documentation necessary to sell, convey, assign, transfer and deliver the applicable T-Mobile Contributor’s right, title and interest in, to and under each Assignable Site and the Included Property of such Assignable Site and (v) amended schedules or exhibits to all other applicable Collateral Agreements.

(a) Subject to Section 2.7(e) , the T-Mobile Contributors and, after the Initial Closing Date, the T-Mobile SPEs shall use commercially reasonable efforts and shall cooperate in good faith with Crown and the Tower Operator to cause any Exceptions to be cured, in each case in accordance with Section 4.3(c) and as promptly as reasonably practicable. Crown and the Tower Operator shall have the right, at any time, to contact Ground Lessors, Tower Subtenants or any other Persons in connection with the transactions contemplated by this Agreement, including in order to identify any Exceptions, whether in person or by telephone, mail or other means of communication, and the T-Mobile Parties (for themselves and the T-Mobile SPEs) hereby authorize such contacts; provided that, prior to the Initial Closing, the T-Mobile Parties and Crown shall coordinate and cooperate in good faith with each other in communicating with Ground Lessors, and each Party shall, to the extent reasonably practicable, provide the other Party the opportunity to attend or participate in any such communications with Ground Lessors.

(b) Upon the cure of any Exceptions with respect to a Site, the T-Mobile Contributors and, after the Initial Closing Date, the T-Mobile SPEs shall provide written notice to Crown and the Tower Operator, identifying the Site together with the related Exceptions that were cured and containing a brief statement regarding how such Exceptions were cured. If Crown and the Tower Operator do not object within 10 business days of receipt of such notice to the assertion by the T-Mobile Contributors or the T-Mobile SPEs, as applicable, that such Exceptions have been cured and (i) if there are no remaining uncured Contribution Exceptions as to any Non-Contributable Site, such Site shall be deemed a Contributable Site, (ii) if there are no remaining uncured Leasing Exceptions as to any Pre-Lease Site, such Site shall be deemed a Lease Site and (iii) if there are no remaining Assignment Exceptions to any Non-Assignable Site, such Site shall be deemed an Assignable Site. All disputes over the method of cure with respect to an Exception shall be resolved by the dispute resolution process described in Section 4.4 .

(c) Until the Initial Closing Date, T-Mobile, on behalf of the T-Mobile Contributors and, after the Initial Closing Date, the T-Mobile SPEs, shall respond as soon as practicable (but in any event within 10 business days) with respect to any actions, waivers, consents or documents that Crown and the Tower Operator reasonably request from the T-Mobile Parties or the T-Mobile SPEs with respect to the identification and curing of Exceptions, including in connection with obtaining Ground Lessor Estoppels and Non-Disturbance Agreements.

SECTION 4.3 Shared Sites; Excluded Sites; T-Mobile Contributors’ Cure Rights .

(a) Shared Sites . The T-Mobile Contributors shall use commercially reasonable efforts to cause any Shared Site to be bifurcated; provided , however , that if such Shared Site is not bifurcated prior to the Applicable Closing Date in a manner satisfactory to Crown acting in good faith, such Shared Site shall be an Excluded Site hereunder.

(b) Excluded Sites . The T-Mobile Parties may elect, in their sole discretion, by written notice to Crown given at any time prior to the Initial Closing Date, to exclude from the transactions contemplated by this Agreement, subject to Section 10.4 , (i) any Casualty Site, (ii) any Non-Compliant Site, (iii) any Portfolio Sites subject to Transaction Revenue Sharing in accordance with Section 4.8 , and (iv) any other Site (each such excluded Site, an “ Excluded Site ”); provided , however , that the T-Mobile Parties may designate no more than 50 Excluded Sites pursuant to clause (iv) of this Section 4.3(b) . Crown may elect, to the extent permitted under and in accordance with Section 2.6 , to exclude from the transactions contemplated by this Agreement the CA/NV Sites and designate such CA/NV Sites as Excluded Sites. Upon the designation of a Site as an Excluded Site in accordance with this Agreement, all references to such Site in the representations and warranties contained in this Agreement shall be deemed to have been deleted from and after the date of such designation.

(c) Cure; Excluded Sites . With respect to each Site subject to an Exception that has not been cured or waived, the T-Mobile Contributors and the T-Mobile SPE may, in their sole discretion, elect any of the following options to cure such Exception and, upon the taking of such action, such Exception shall be deemed to have been cured by T-Mobile Contributors:

(i) Title Insurance . If such Exception relates solely to title, if the Title Company shall have committed to issue to the Tower Operator or, after the Initial Closing, the applicable Sale Site Subsidiary, without indemnity from the Tower Operator or such Sale Site Subsidiary but following the Tower Operator’s or such Sale Site Subsidiary’s payment of the applicable premium, a leasehold title insurance policy (or lender’s policy, as applicable) in the case of a Leased Site or a fee title insurance policy in the case of an Owned Site (which policy is acceptable, including as to the applicable premium and coverage amount, to the Tower Operator or such Sale Site Subsidiary in its reasonable discretion) without exception for such Exception (other than standard printed exceptions), or with affirmative coverage over such Exception; or

(ii) Corrective Action . If the T-Mobile Contributors or the T-Mobile SPEs shall have taken corrective action with respect to such Exception (including, by way of example, by obtaining required consents or approvals from third parties, by obtaining Ground Lessor Estoppels, by acquiring rights or property from third parties, by obtaining or providing any affidavits or certificates or otherwise) in a manner that is reasonably acceptable to Crown and, if applicable, the Title Company, and that cures such Exception.

SECTION 4.4 Dispute Resolution .

(a) The Parties intend to provide for an expedited dispute resolution process during the period from the Signing Date until the Applicable Closing that shall resolve any and all disputes solely with respect to the Site Designation of any Portfolio Site or whether any Exceptions to any Portfolio Site have been cured (each a “ Site Designation Pre-Closing Dispute ”). As such, any Site Designation Pre-Closing Dispute shall be subject to the dispute resolution process provided in this Section 4.4 . Should a Party wish to initiate a dispute resolution process with respect to any Site Designation Pre-Closing Dispute, it shall first deliver to the other Parties a written notice (a “ Notice of Dispute ”) that specifies in reasonable detail the Site Designation Pre-Closing Dispute that such Party wishes to have resolved.

(b) If the Parties are not able to resolve any Site Designation Pre-Closing Dispute within 10 days of a Party’s receipt of an applicable Notice of Dispute, then such Site Designation Pre-Closing Dispute shall be promptly submitted to the Settlement Firm for resolution and the Settlement Firm shall determine the Site Designation of the Portfolio Site subject to such Site Designation Pre-Closing Dispute. The T-Mobile Parties and Crown shall cooperate with the Settlement Firm and shall proceed reasonably and in good faith to cause the Settlement Firm to resolve any Site Designation Pre-Closing Dispute not later than 10 days after the engagement of the Settlement Firm with respect thereto. Crown, on the one hand, and the T-Mobile Parties, on the other hand, each shall pay one-half of the fees and expenses of the Settlement Firm. The Settlement Firm’s resolution of the disagreement shall be reflected in a written report, which report shall be delivered promptly to Crown and the T-Mobile Parties and shall set forth the Settlement Firm’s determination of the Site Designation for the Portfolio Site subject to the Site Designation Pre-Closing Dispute. Judgment may be entered upon the Settlement Firm’s report in any court having jurisdiction over the Party against which such report is to be enforced. The Parties agree that the Site Designation of any Portfolio Site, as determined by the Settlement Firm pursuant to this Section 4.4(b) , shall be the Final Site Designation of such Site.

(c) The Settlement Firm conducting any dispute resolution shall be bound by, and shall not have the power to modify, the provisions of this Agreement. Without limiting the foregoing, any determination of the valuation of a Site made by the Settlement Firm shall be made in accordance with Article 3 . Unless otherwise provided in Section 4.8 or Section 4.9 , each Party shall pay its own costs, fees and expenses (including for counsel, experts and presentation of proof) in connection with any dispute resolution under this Section 4.4 ; provided , however , that the expenses and fees of the Settlement Firm shall be shared equally by T-Mobile (on behalf of the T-Mobile Parties) and Crown.

(d) Subject to Section 1.3 , Section 2.7(c) , Section 2.9 , Section 4.4 , Section 4.8 and Section 4.9 , each Party agrees that the dispute resolution process conducted pursuant to this Section 4.4 is the exclusive mechanism for the resolution of disputes with respect to the subjects referred to in Section 4.4(a) or any other provision of this Agreement that makes reference to this Section 4.4 and agrees that no action, suit or proceeding may be brought in any other forum relating to any such matters.

SECTION 4.5 Special Zoning Sites .

(a) If prior to the Closing with respect to a Site, the T-Mobile Parties or Crown discover that a Site constitutes a Special Zoning Site, the T-Mobile Parties or Crown, as the case may be, shall promptly provide written notice to the other Parties that it in good faith considers such Site to be a Special Zoning Site, and provide notice in reasonable detail of the reasons therefor. If such other Parties do not object within 10 business days of receipt of such notice, such Site shall be deemed to be a Special Zoning Site. All Site Designation Pre-Closing Disputes concerning the designation of a Site as a Special Zoning Site shall be resolved by the dispute resolution process described in Section 4.4 . If an MPL Site is a Special Zoning Site or a Sale Site is a Special Zoning Site, then such Site shall be deemed a Non-Contributable Site or Non-Assignable Site, as applicable, and the provisions of Section 4.2 with respect to the curing of Exceptions shall apply, mutatis mutandis, to remedying the circumstances causing such Site to be a Special Zoning Site.

SECTION 4.6 Casualty Sites .

(a) If, prior to the Applicable Closing, the T-Mobile Parties or Crown discover that a Site constitutes a Casualty Site, the T-Mobile Parties or Crown, as the case may be, shall promptly notify the other Parties in writing that it considers such Site to be a Casualty Site, with reasonable specificity as to the reasons therefor. If such other Parties do not object within 10 business days of receipt of such notice, such Site shall be deemed to be a Casualty Site. All Site Designation Pre-Closing Disputes concerning the designation of a Site as a Casualty Site shall be resolved by the dispute resolution process described in Section 4.4 .

(b) If a Site is deemed a Casualty Site, then:

(i) Excluded Site . If such Site is a Casualty Site as a result of a condemnation (or pending condemnation) or a foreclosure, deed-in-lieu of foreclosure or similar proceeding involving a Lien or Ground Lessor Mortgage, any Party may elect by written notice to the other Parties given no later than 5 business days prior to the Applicable Closing to exclude such Casualty Site from the transactions contemplated by this Agreement (any such Casualty Site no longer being referred to as a Casualty Site and being referred to as an Excluded Site).

(ii) Damaged Sites . If such Site is a Casualty Site as a result of physical damage prior to the Applicable Closing Date (a “ Damaged Site ”), the T-Mobile Parties may, at their option, (A) elect to repair, at their sole cost and expense, the Tower so as to bring the condition of such Tower to substantially the same (or better) condition that it was in immediately prior to the event or occurrence of the event causing such Tower to be designated as a Damaged Site (as determined by Crown in good faith) or (B) elect to reimburse Crown for the amount estimated by Crown in good faith to be required to complete the repair of the Tower and, promptly upon the receipt of an invoice from Crown or the Tower Operator, any actual out-of-pocket expenses incurred by Crown or the Tower Operator to so repair the Tower in excess of such estimated amount paid, if any. With respect to each Damaged Site, if the T-Mobile Parties or T-Mobile SPEs elect not to repair the Tower or pay Crown to repair the Tower pursuant to this Section 4.6(b) no later than 5 business days prior to the Applicable Closing, then such Damaged Site shall be treated as an Excluded Site as if the T-Mobile Parties and the T-Mobile SPEs had elected to exclude such Damaged Site pursuant to Section 4.2(a) .

SECTION 4.7 Allocation of Rent . After the Closing Total Consideration is determined and prior to the Initial Closing Date, the T-Mobile Contributors shall cause to be delivered to Tower Operator a draft of Exhibit D to the MPL based on the financial information for the Sites used to calculate the Closing Total Consideration in accordance with Article 3 . The method of allocating the prepaid rent for an MPL Site among the years in the applicable lease term as required for such Exhibit D shall be within the safe harbors permitted by Section 467 of the Code and Treasury Regulation §1.467-3(c)(3) (the “ 467 Safe Harbor Rules ”) and otherwise as proposed by T-Mobile Contributors in a draft of such Exhibit D , and the T-Mobile Contributors’ draft of such Exhibit D shall be incorporated into the MPL. In addition, promptly after the Final Total Consideration is determined, the T-Mobile Contributors shall cause to be delivered to the Tower Operator a revised draft of Exhibit D to the MPL based on the financial information for the Sites used to calculate the Final Total Consideration in accordance with Article 3 . Provided such revised draft complies with the 467 Safe Harbor Rules and absent any manifest error, the T-Mobile Contributors’ revised draft of such Exhibit D shall be incorporated into the MPL.

SECTION 4.8 Transaction Revenue Sharing Payments .

(a) The Parties acknowledge and agree that it is in the best interests of each Party to determine on or prior to the Initial Closing Date whether any Transaction Revenue Sharing Payments exist or could reasonably be expected to become due and payable and, where possible, to quantify the amounts thereof. As a result, prior to the Initial Closing, the T-Mobile Parties shall use commercially reasonable efforts to identify any such Transaction Revenue Sharing Payments and notify Crown thereof. Each Party shall further promptly notify the other Parties in the event that any Ground Lessor makes a claim or demand for a Transaction Revenue Sharing Payment.

(b) If the T-Mobile Parties reasonably and in good faith determine that Transaction Revenue Sharing Payments are reasonably likely to become due and payable with respect to any MPL Site following the consummation of the transactions contemplated by this Agreement and the Collateral Agreements, the T-Mobile Parties and the T-Mobile SPEs shall have the right, in their discretion but in consultation with Crown and the Tower Operator, (i) prior to the Initial Closing, to designate such Site as a Managed MPL Site, a Sale Site or an Excluded Site and (ii) after the Initial Closing, to rescind the transaction that occurred with respect to such MPL Site at the applicable Closing and (x) designate and treat such MPL Site as a Managed Site and grant to the Tower Operator or the applicable Sale Site Subsidiary, as applicable, pursuant to the Management Agreement, the right to operate such Site as a Managed Site and administer the related Collocation Agreements or (y) designate and treat such MPL Site as an Assignable Site and sell, assign and transfer such Site to the applicable Sale Site Subsidiary pursuant to this Agreement or similar purchase and sale documentation that is reasonably satisfactory to the Tower Operator; provided that, in each case, such designation and, if applicable, the rescission of such transactions shall eliminate, in the reasonable determination of Crown and T-Mobile, the grounds for such Transaction Revenue Sharing Payment with respect to such MPL Site; and provided further that, in the case of a rescission and re-designation of an MPL Site following the Initial Closing, (A) such re-designation would not have resulted in the failure of either the Minimum Lease Site and Assignable Site Closing Condition or the Minimum Contributable Site and Assignable Site Closing Condition as of the Initial Closing Date if such MPL Site had been initially designated as such by the T-Mobile Parties at the Initial Closing, (B) upon the exercise of such right, the T-Mobile Parties and the T-Mobile SPEs shall, in the case of a rescission and the re-designation of a Lease Site as a Managed Site, promptly (but in no event later than two business days following request therefor) refund to Crown the Deferred Managed Site Consideration for such Site (if a positive number), together with interest thereon at the Interest Rate, calculated on the basis of the actual number of days elapsed divided by 360, from the date of payment of the Closing Lease Site Rent for such Site to the date of refund ( provided that if the Deferred Managed Site Consideration for such Site is a negative number, Crown shall pay the T-Mobile Parties and the T-Mobile SPEs an amount equal to the absolute value of the Deferred Managed Site Consideration for such Site, including interest thereon at the Interest Rate, calculated on the basis of the actual number of days elapsed divided by 360, from the date of payment of the Closing Lease Site Rent for such Site to the date of such payment), (C) in the case of a rescission and the re-designation of a Lease Site as an Assignable Site or an Managed MPL Site as a Sale Site, the sale, transfer and assignment of such Site to the applicable Sale Site Subsidiary shall be at no additional cost and expense to, and with no additional consideration to be paid by, Crown, and (D) upon the exercise of such right, the T-Mobile Parties and the T-Mobile SPEs shall take all other actions and execute all documents reasonably necessary (and any necessary amendments to existing documentation as appropriate) to ensure that the Parties are in the same legal and economic position as they would have been if such Site were originally a Managed Site or an Assignable Site, as the case may be. For the avoidance of doubt, notwithstanding anything to the contrary set forth herein, no MPL Site can be re-designated as a CA/NV Site.

(c) In furtherance of the foregoing, and notwithstanding anything to the contrary contained in this Agreement, the T-Mobile Parties and the T-Mobile SPE shall be responsible for reimbursing, and shall promptly (but in no event later than 10 business days following request therefor) reimburse, Crown and the Tower Operator for all costs and expenses incurred by any of them in connection with the actions and transactions described in this Section 4.8 .

SECTION 4.9 Material Site Title Issue or Material Site Non-Compliance Issue Arising Prior to the Applicable Date Closing .

(a) If, at any time on or prior to the Applicable Closing Date, Crown determines in good faith that a Site has a Material Site Title Issue or a Material Site Non-Compliance Issue, Crown shall send T-Mobile a Notice of Dispute with respect to such Site explaining the reason for such determination in reasonable detail, along with reasonable supporting documentation. Within 10 days of delivery of such Notice of Dispute, T-Mobile shall deliver written notice to Crown that it either agrees that such Site is a Non-Compliant Site (a “ Site Non-Compliance Agreement Notice ”) or that it disagrees that such Site is a Non-Compliant Site (a “ Site Non-Compliance Dispute Notice ”). If the Notice of Dispute lists more than one Site, T-Mobile shall deliver a Site Non-Compliance Agreement Notice for all Sites where it agrees with the Notice of Dispute and a Site Non-Compliance Dispute Notice for all Sites where it disagrees with the Notice of Dispute. The failure of T-Mobile to respond within such 10-day period shall be deemed a delivery by T-Mobile to Crown of a Site Non-Compliance Agreement Notice. The Parties shall work together, acting in good faith, to reach agreement regarding any dispute as to whether a Site is a Non-Compliant Site. In no event shall Crown’s delivery of a Notice of Dispute alleging that a Site is a Non-Compliant Site or a dispute regarding whether a Site is a Non-Compliant Site delay the Applicable Closing.

(b) Upon delivery or deemed delivery of a Site Non-Compliance Agreement Notice by T-Mobile to Crown with respect to a Site, such Site shall be deemed an Excluded Site. If the Parties cannot agree whether a Site is a Non-Compliant Site, the dispute shall be promptly submitted to the Settlement Firm for resolution in accordance with Section 4.4 .

(c) If a dispute over whether a Site is a Non-Compliant Site is pending on the Applicable Closing Date, such Site shall not be deemed a Non-Compliant Site (and such Site shall be included in the Sites that are the subject of the Applicable Closing); provided , however , that if such Site is later determined, as a result of the dispute resolution process pending under Section 4.4 , to be a Non-Compliant Site, such Site shall be deemed an Excluded Site for all purposes of this Agreement and the Parties shall take all actions, make all payments and execute all documents reasonably necessary to ensure that: (i) the transactions that occurred with respect to such Site on the applicable Closing under this Agreement and the Collateral Agreements are rescinded and (ii) the Parties are in the same legal and economic position as they would have been if such Site were originally an Excluded Site, including T-Mobile or Crown, as the case may be, refunding any applicable portion of the Closing Total Consideration, Subsequent Closing CA/NV Total Consideration or Final Total Consideration, as applicable, and any Deferred Managed Site Consideration applicable to such Site to Crown (if the applicable portion was a positive number) and to T-Mobile (if the applicable portion was a negative number), net of any Excluded Site Collocation Payments theretofore paid to or received by Crown or the Tower Operator.

(d) In furtherance of the foregoing, and notwithstanding anything to the contrary contained in this Agreement, the T-Mobile Parties and the T-Mobile SPE shall be responsible for reimbursing, and shall promptly (but in any event no later than 10 business days following request therefor) reimburse, Crown and the Tower Operator for all out-of-pocket costs and expenses incurred by any of them in connection with any Non-Compliant Site, including any related dispute resolution process under Section 4.4 or any actions taken by Crown or the Tower Operator pursuant to Section 4.9(c) .

(a) Any Party asserting a claim for indemnification (the “ 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 this Article 12 , except to the extent (and only to the extent) the delay actually and materially prejudices the Indemnifying Party’s ability to defend such Claim.

(b) 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 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.

(c) 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.

(d) 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 Article 12 . 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 12.1(a) , Section 12.1(b) , Section 12.2(a) or Section 12.2(b) , as applicable, such Claim specified by the Indemnified Party in such notice shall be conclusively deeded a liability of the Indemnifying Party under Section 12.1(a) , Section 12.1(b) , Section 12.2(a) or Section 12.2(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 Section 14.12 and Section 14.13 .

(e) The T-Mobile Contributors and their Affiliates shall control the defense of all Claims related to Excluded Liabilities.

(e) By either the T-Mobile Parties or Crown, if any permanent injunction, decree or judgment of any Governmental Authority preventing consummation of the transactions contemplated by this Agreement and the Collateral Agreements shall have become final and nonappealable or any Law shall make consummation of the transactions contemplated by this Agreement and the Collateral Agreements illegal or otherwise prohibited; or

(f) By the T-Mobile Parties; provided that the T-Mobile Parties, the T-Mobile SPEs and the Sale Site Subsidiaries are not then in material breach of any of their obligations under this Agreement, if (i) all of the conditions set forth in Article 10 (other than Section 10.5 ) have been satisfied (other than those conditions that by their nature are to be satisfied by actions taken at the Initial Closing) on the date the Initial Closing should have occurred pursuant to Section 2.6 , (ii) Crown and the Tower Operator fail to consummate the transactions contemplated by this Agreement within three business days of the date the Initial Closing should have occurred pursuant to Section 2.6 and (iii) the T-Mobile Parties, the T-Mobile SPEs and the Sale Site Subsidiaries have irrevocably committed, by written notice to Crown that all conditions set forth in Article 11 have been satisfied (other than those conditions that by their nature are to be satisfied by actions taken at the Initial Closing) or that they are willing to waive any unsatisfied conditions (to the extent such conditions may be waived) in Article 11 , to consummate the transactions contemplated by this Agreement on such date.

SECTION 13.2 Effect of Termination .

(a) If terminated pursuant to Section 13.1 , this Agreement shall terminate and become null and void and have no effect, without any liability on the part of any Party or its Affiliates, directors, officers or stockholders, except that: (i) Section 5.9 , Section 7.6 , Section 9.1(a) , Section 9.5 , Section 9.6 , Section 9.11(a) , Section 9.11(b) (in so far as it relates to information relating to this Agreement, the Collateral Agreements or the transactions contemplated hereby), this Article 13 and Article 14 shall survive any termination, (ii) any provisions not covered by clause (i) requiring the payment or reimbursement of any costs or expenses relating to, or incurred during, the period from the Signing Date to the Initial Closing Date shall survive any termination until paid in full and (iii) subject in all cases to Section 13.3 , any such termination shall not relieve any Party from liability for fraud. With respect to the provisions that expressly survive termination, each of Crown and the T-Mobile Parties shall be entitled to pursue any and all rights and remedies to which it or they may be entitled at Law or in equity.

SECTION 13.3 Termination Fee .

(a) In the event that this Agreement is terminated by the T-Mobile Parties, pursuant to Section 13.1(f) Crown shall pay to T-Mobile, on behalf of the T-Mobile Parties, the T-Mobile SPEs and the Sale Site Subsidiaries, a termination fee in an amount equal to $250,000,000 (the “ Termination Fee ”); it being understood that in no event shall Crown be required to pay the Termination Fee on more than one occasion. Any amount due under this Section 13.3(a) shall be paid by wire transfer of same-day funds to an account provided in writing by T-Mobile to Crown within two business days of the date of such termination.

(b) Notwithstanding anything to the contrary contained in this Agreement, T-Mobile’s right, on behalf of the T-Mobile Parties, the T-Mobile SPEs and the Sale Site Subsidiaries, to receive payment of the Termination Fee pursuant to Section 13.3(a) shall constitute the sole and exclusive remedy of the T-Mobile Parties, the T-Mobile SPEs and the Sale Site Subsidiaries and their respective Affiliates for any and all Claims suffered as a result of the failure of the transactions contemplated by this Agreement to be consummated or for any breach or failure to perform hereunder at or prior to the Initial Closing, and upon payment of the Termination Fee, none of Crown, the Tower Operator and any of their Affiliates or Representatives shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by this Agreement or in respect of any Collateral Agreement or theory of Law or equity, whether in equity or at Law, in contract, in tort or otherwise.

(c) Each Party acknowledges and agrees that the agreements contained in this Section 13.3 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, the other Parties would not have entered into this Agreement. Accordingly, if Crown fails to timely pay the Termination Fee as required hereby and, in order to obtain the payment of the Termination Fee, T-Mobile commences an Action which results in a judgment against Crown for the payment of the Termination Fee, Crown shall pay T-Mobile its reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees) in connection with such suit, together with interest thereon at the prime rate (as published in the Wall Street Journal) in effect on the date payment of the Termination Fee was required to be made through the date such payment was actually received by T-Mobile.

(iv) If for any given month during the Term the aggregate Ground Rent for all Sites hereunder exceeds the aggregate T-Mobile Total Rent Amount for all Sites hereunder, Tower Operator shall pay or cause to be paid such excess aggregate Ground Rent (the " Tower Operator Ground Rent ") to the Paying Agent (by a transfer to the Paying Agent Account) for distribution to the Ground Lessors or the applicable T-Mobile Collocator if a Triggering Event has occurred and T-Mobile Collocator has paid Ground Rent directly to the applicable Ground Lessor.

(c) Prorated Rent Payments . If the Effective Date is a day other than the first day of a calendar month, (i) the applicable T-Mobile Collocation Rent for the period from the Effective Date through the end of the calendar month during which the Effective Date occurs (the " Initial Period ") shall be prorated on a daily basis, and shall be included in the calculation of and payable with the T-Mobile Collocation Rent for the first full calendar month of the Term, and (ii) T-Mobile Collocator shall timely pay, to the extent it has not already paid, to each Ground Lessor directly, the Ground Rent due and payable under the respective Ground Lease for the Initial Period. If the date of the expiration of the Term as to any Site is a day other than the last day of a calendar month, the applicable T-Mobile Total Rent Amount for such calendar month shall be prorated on a daily basis.

(d) Revenue Sharing Payments . T-Mobile Collocator shall pay to Tower Operator (or to the applicable Ground Lessor (x) if required to be paid directly to such Ground Lessor by the terms of the applicable Ground Lease, (y) if a Triggering Event shall have occurred and be continuing or (z) if so instructed by Tower Operator), as and when due and payable under any Ground Lease, T-Mobile's Share of Transaction Revenue Sharing Payments (as defined in the Master Agreement) that are required to be made with respect to the T-Mobile Total Rent Amount for any Site other than Tower Operator Negotiated Increased Revenue Sharing Payments. Each payment of such Transaction Revenue Sharing Payments by T-Mobile Collocator shall identify and specify the Site in respect of which such payment is being made. To the extent T-Mobile Collocator shall have a continuing obligation to make Revenue Sharing payments with respect to any Site for which T-Mobile Collocator has made an initial Revenue Sharing payment in accordance with the immediately preceding sentence, T-Mobile Collocator shall make such continuing Revenue Sharing payments on the same date that such payments are due and payable to the applicable Ground Lessor. Tower Operator shall pay, as and when due and payable, Tower Operator Share of Transaction Revenue Sharing Payments (as defined in the Master Agreement) that are required to be made with respect to the T-Mobile Total Rent Amount for any Site.

(e) Tower Operator Right to Cure Ground Rent Defaults .

(f) Termination of Rent Obligation . Notwithstanding anything to the contrary contained herein, if T-Mobile Collocator is not able to use or occupy the T-Mobile Collocation Space at a Site for the current or future business activities that it conducts at such Site because of the termination of the underlying Ground Lease, or the failure of Tower Operator to comply with the terms and conditions of this Agreement or the MPL following applicable notice and cure periods, (i) T-Mobile Collocator shall have no further obligation to pay the T-Mobile Collocation Rent or T-Mobile Ground Rent applicable to such Site and (ii) T-Mobile Collocator shall have the right to offset any amounts owed by Tower Operator to T-Mobile Collocator hereunder against the T-Mobile Collocation Rent, the T-Mobile Ground Rent or any other amounts that may become due from T-Mobile Collocator and payable to Tower Operator under this Agreement. The foregoing shall not limit any other rights or remedies of T-Mobile Collocator hereunder.

SECTION 5. Ground Leases.

(a) Compliance With Ground Leases . Except with respect to the Ground Rent that T-Mobile Collocator is obligated to pay pursuant to Section 4 , 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. To the extent that any Ground Lease imposes or requires the performance of the "ground lessee" thereunder of any duty or obligation that is more stringent than or in conflict with any term, covenant, condition or provision of this Agreement, the applicable term, covenant, condition or provision of such Ground Lease shall control and shall constitute the duties and obligations of Tower Operator under this Agreement as to the subject matter of such term, covenant, condition or provision. Tower Operator shall be responsible for any breaches of, or defaults under, any Ground Lease that are caused by Tower Operator's authorized agents and employees. 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 T-Mobile Collocator, any T-Mobile Lessor or any T-Mobile Group Member.

(b) Tower Operator Rights Under Ground Leases . Tower Operator shall be entitled, subject to the provisions of Section 32 , to review, negotiate and execute any Tower Operator Negotiated Renewal, waiver, amendment, extension, renewal, sequential lease, adjacent lease, non-disturbance agreement and other documentation relating to Ground Leases that (i) Tower Operator determines in good faith is on commercially reasonable terms, (ii) is of a nature and on terms to which Tower Operator would agree (in light of the circumstances and conditions that exist at such time) in the normal course of business if it owned the property to which the Ground Lease relates and (iii) otherwise satisfies the following requirements of this Section 5 (each, an " Authorized Ground Lease Document "). T-Mobile Collocator agrees to execute and deliver, as promptly as reasonably practicable and in any event within 10 Business Days following request therefor by Tower Operator, any Authorized Ground Lease Document, any Authorized Collocation Agreement Document and any other document contemplated and permitted by this Agreement or necessary to give effect to the intent of this Agreement and the other Transaction Documents.

(c) 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 has given a Termination Notice relating to such Site.

(d) Negotiation of Additional Ground Lease Extensions .

(i) Tower Operator shall be entitled to negotiate and obtain, in accordance with the provisions of Section 32 , the further extension of the term of all Ground Leases subject to the provisions of Section 5(b) and this Section 5(d) .

(ii) Tower Operator shall provide T-Mobile Collocator with notice (a " Tower Operator Extension or Relocation Notice ") 180 days prior to the expiration of any Ground Lease which does not include provisions of renewal beyond the scheduled expiration date (other than any such Ground Lease that is scheduled to expire within 24 months following the Effective Date). The Tower Operator Extension or Relocation Notice shall set forth (A) Tower Operator's intent to negotiate an extension or renewal of such Ground Lease (in which case Tower Operator shall provide subsequent notification of the progress of such negotiations, including the successful completion of the negotiations) or (B) Tower Operator's intent to pursue an alternative site that is in all material respects suitable for T-Mobile Collocator's use at no additional cost to T-Mobile Collocator (in which case such notice shall also describe Tower Operator's plans to relocate T-Mobile Communications Equipment in a manner that shall result in no costs to T-Mobile Collocator and no interruption of T-Mobile Collocator's business). In the event Tower Operator elects to pursue an alternative site, and such alternative site is satisfactory to T-Mobile Collocator, in its reasonable and good faith determination, T-Mobile Collocator shall enter into a lease or sublease agreement with Tower Operator with respect to such alternative site and the T-Mobile Communications Equipment shall be relocated to such alternative site.

(iii) If Tower Operator fails to timely deliver a Tower Operator Extension or Relocation Notice or T-Mobile Collocator, in its reasonable discretion, determines that Tower Operator's plans for an alternative site are not acceptable, the applicable T-Mobile Lessor shall have the right, but not the obligation, to commence negotiations with the applicable Ground Lessor under the expiring Ground Lease ( provided that such T-Mobile Lessor (and its Affiliates) may not commence such negotiations until the date that is 120 days prior to the expiration date of the applicable Ground Lease (or until the date that is 60 days prior to the expiration date of the applicable Ground Lease in the case of a Ground Lease the Ground Lessor in respect of which is a Governmental Authority)) and shall act in good faith to not undermine or adversely affect Tower Operator's economic interests in the applicable Site at any time (including by enlisting the direct or indirect support of a Lease Buyout Firm). Upon notice from the applicable T-Mobile Lessor that it intends to commence such negotiations, Tower Operator shall cease all efforts to negotiate an extension or renewal of the applicable Ground Lease and such T-Mobile Lessor may negotiate an extension or renewal of the applicable Ground Lease on terms and conditions that such T-Mobile Lessor determines in its reasonable discretion. If the applicable T-Mobile Lessor completes the foregoing negotiations for, and executes, such Ground Lease extension or renewal, then such T-Mobile Lessor shall provide notice to Tower Operator of same (the " T-Mobile Lessor Extension Notice ") and the applicable MPL shall terminate as to the applicable Site as of the day immediately preceding the commencement of such Ground Lease extension or renewal and shall have no further force and effect except for the obligations accruing prior to or as of the termination date for such Site, unless Tower Operator elects to resume its obligations under the applicable MPL and Section 5(a) to comply with all terms, covenants, conditions and provisions of such Ground Lease as if Tower Operator were the "ground lessee" under such Ground Lease by notifying such T-Mobile Lessor of same within 30 days of its receipt of the T-Mobile Lessor Extension Notice. If Tower Operator elects to resume its obligations under the applicable MPL and Section 5(a) , then (x) Tower Operator shall indemnify the applicable T-Mobile Lessor for all reasonable costs incurred in connection with the extension or renewal of such Ground Lease and shall be responsible for all incremental costs relating to such Ground Lease going forward, (y) Tower Operator shall accept and comply with the terms of such Ground Lease as negotiated by such T-Mobile Lessor and (z) the applicable MPL and this Agreement shall continue in full force and effect as if such extension or renewal was a Tower Operator Negotiated Renewal.

(iv) The failure of Tower Operator to provide a Tower Operator Extension or Relocation Notice shall not constitute an event of default or allow T-Mobile Collocator to exercise remedies under this Agreement if the expiring Ground Lease is nevertheless extended or renewed, or a new Ground Lease or similar arrangement is entered into, prior to the Ground Lease's expiration.

(v) If a Ground Lease expires before the term of the applicable MPL or this Agreement expires with respect to any Site, then this Agreement shall have no further force and effect as to the T-Mobile Collocation Space within such Site except for the obligations accruing prior to or as of the expiration date for such Site that are then unperformed.

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 33(i) and 33(j) .

(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 Tower Operator fails to give Casualty Notice to T-Mobile Collocator within such 60-day period, the affected Site shall be deemed to be a Restorable Site. If T-Mobile Collocator disagrees with any determination of Tower Operator in the Casualty Notice that the Site is a Non-Restorable Site, T-Mobile Collocator may institute arbitration proceedings to determine any such matter in the manner described in Section 25(f) . If such Site is a Non-Restorable Site, then (i) either 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 and (ii) pursuant to the terms and conditions in the MPL, the applicable T-Mobile Lessor or the applicable T-Mobile Ground Lease Additional Party, as applicable, shall have the right to terminate the MPL as to such Site by written notice to Tower Operator within the time period required below, whereupon the Term as to such Site shall automatically expire as of the date of such notice of termination and T-Mobile Collocator's rights and obligations as to the leaseback or other use and occupancy of T-Mobile Collocation Space at such Site shall automatically expire as of the date of such notice of termination. Any such notice of termination shall be given not later than 30 days after receipt of the Casualty Notice (or after final determination that the Site is a Non-Restorable Site if arbitration is instituted as provided above). In all instances Tower Operator shall have the sole right to retain all insurance Proceeds related to a Non-Restorable Site.

(b) If there occurs, as to any Site, a casualty that damages or destroys (i) all or a Substantial Portion of such Site and the Site is a Restorable Site, or (ii) less than a Substantial Portion of any Site, then Tower Operator, at its sole cost and expense, shall promptly commence and diligently prosecute to completion, within a period of 60 days after the date of the damage, the adjustment of Tower Operator's insurance Claims with respect to such event and, thereafter, promptly commence, and diligently prosecute to completion, the Restoration of the Site. The Restoration shall be carried on and completed in accordance with the provisions and conditions of this Section 30 .

(c) If Tower Operator is required to restore any Site in accordance with Section 30(b) , all Proceeds of Tower Operator's insurance Claims with respect to the related casualty shall be held by Tower Operator or the Tower Operator Lender and applied to the payment of the costs of the Restoration and shall be paid out from time to time as the Restoration progresses. Any portion of the Proceeds of Tower Operator's insurance applicable to a particular Site remaining after final payment has been made for work performed on such Site may be retained by and shall be the property of Tower Operator. If the cost of Restoration exceeds the Proceeds of Tower Operator's insurance, Tower Operator shall pay the excess cost.

(d) Without limiting Tower Operator's obligations under this Agreement in respect of a Site subject to a casualty, if Tower Operator is required to cause 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 Subtenants 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 Subtenant; (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.

(e) If Tower Operator fails at any time to diligently pursue the substantial completion of the Restoration of a Site required under this Agreement (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, in addition to any other available remedy, 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.

(f) 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 and the T-Mobile Ground Rent with respect to such Site shall abate until completion of the Restoration.

(g) 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 a Lease Site, or unable to operate such Site, if a Managed Site, by reason of such Taking, the failure to keep, observe, perform, satisfy and comply with those terms and conditions of this Agreement compliance with which are effectively impractical or impossible as a result of Tower Operator's being out of possession of or unable to operate (as 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 and the T-Mobile Ground Rent during the period of the temporary Taking.

SECTION 32. Operating Principles.

(a) During the Term of a Site, Tower Operator shall manage, operate and maintain such Site (including with respect to the entry into, modification, amendment, extension, expiration, termination, structuring and administration of Ground Leases and Collocation Agreements related thereto), (i) in the ordinary course of business, (ii) in compliance with applicable Law in all material respects, (iii) in a manner consistent in all material respects with the manner in which Tower Operator manages, operates and maintains its portfolio of telecommunications tower sites and (iv) in a manner that shall not be less than the general standard of care in the tower industry. Without limiting the generality of the foregoing, during the Term of a Site, except as expressly permitted by the terms of this Agreement, Tower Operator shall not without the prior written consent of T-Mobile Collocator (A) manage, operate or maintain such Site in a manner that would (x) diminish the expected residual value of such Site in any material respect or shorten the expected remaining economic life of such Site, in each case determined as of the expiration of the Term of such Site, or (y) cause such Site or a substantial portion of such Site to become "limited use property" within the meaning of Rev. Proc. 2001-28, 2001-1 C.B. 1156 (except, in the case of this clause (y), as required by applicable Law or any Governmental Authority), (B) structure any related Ground Lease in a manner such that the amounts payable thereunder are above fair market value during any period following or upon the expiration of the Term of such Site (without regard to any amounts payable prior to the expiration of the Term of such Site) or (C) structure any related Collocation Agreement in a manner such that the amounts payable thereunder are less than fair market value during any period following or upon expiration of the Term of such Site (without regard to any amounts payable prior to the expiration of the Term of such Site), in each case unless otherwise expressly authorized by the terms and conditions of this Agreement and the Transaction Documents.

(b) During the Term of a Site, T-Mobile Collocator shall manage, operate and maintain the T-Mobile Collocation Space at such Site (i) in the ordinary course of business, (ii) in compliance with applicable Law in all material respects, (iii) in a manner consistent in all material respects with the manner in which T-Mobile Collocator manages, operates and maintains its other collocation spaces and (iv) in a manner that shall not be less than the general standard of care in the telecommunications industry.

(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.

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 34 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.

T-Mobile Parent agrees that if T-Mobile Collocator (all references to T-Mobile Collocator in this Section 34 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.

(e) For the avoidance of doubt, the T-Mobile Collocator Obligations shall not include any obligations of Crown Castle International Corp. under the terms of the Parent Indemnity Agreement.
