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.

SECTION 2.7 Technical Closings; Contributions to T-Mobile SPEs.

(a) The Parties shall hold a Technical Closing on such dates as either T-Mobile or Crown may reasonably request (but in no event shall a Technical Closing be held on a day that is not a business day or more frequently than once a month), subject to the requesting Party providing the other Parties with at least 5 business days’ notice prior to the date of such Technical Closing; provided that the effective Closing Date for each Site that is converted from a Non-Contributable Site to a Contributable Site, from a Pre-Lease Site to a Lease Site or from a Non-Assignable Site to an Assignable Site shall be the Conversion Closing Date for such Site.

(b) At each Technical Closing, each Party shall have executed and delivered to the other Parties, 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) with respect to each Non-Assignable Site that is the subject to such Technical Closing, the documentation necessary to sell, convey, assign, transfer and deliver the applicable T-Mobile Contributor’s right, title and interest in, to and under such Site and the Included Property of such Site, (v) amended schedules or exhibits to all other applicable Collateral Agreements, (vi) the certificates and other contracts, documents and instruments required to be delivered under Article 10 and Article 11 with respect to a Technical Closing and (vii) such other agreements and documents as contemplated by Section 2.7 of this Agreement.

(c) Subject to Section 2.7(e)(i), Crown shall pay (by wire transfer as directed in writing by T-Mobile), to the applicable T-Mobile Party or T-Mobile SPE the Deferred Managed Site Consideration for each Managed Site converted to a Lease Site or Assignable Site, as applicable, at such Technical Closing less any Tower Operator Reimbursable Expenses related to such Site.

(d) In addition, at each Technical Closing, if either of the following events has occurred with respect to any Non-Contributable Site or Non-Assignable Site since the previous Technical Closing or the Applicable Closing, as applicable: (i) the Contribution Exceptions or Assignment Exceptions, as applicable, with respect to such Site have been corrected or addressed pursuant to Section 4.2 or Section 4.3 or (ii) the expiration of Crown’s notice period in the second sentence of Section 4.2(b), then T-Mobile Contributors shall contribute, convey, assign, transfer and deliver to the applicable T-Mobile SPE in the case of a Contributable Site, or to the applicable Sale Site Subsidiary (or its designee) in the case of an Assignable Site, all of their respective right, title and interest in, to and under the Included Property of such Sites and the related Collocation Agreements by the execution delivery of the instruments of conveyance and assignment as may be reasonably necessary for the T-Mobile Contributors to contribute, convey, assign, transfer and deliver to such T-Mobile SPEs or Sale Site Subsidiary (or its designee), as applicable, all of their respective right, title and interest in, to and under the Included Property of such Sites and the related Collocation Agreements and amended schedules or exhibits to all applicable Collateral Agreements, in each case, in form and substance reasonably acceptable to the Parties.

(e) The T-Mobile Parties and the T-Mobile SPEs may, on at least 10 business days written notice, terminate, effective as of any date 18 months or more after the date of this Agreement as specified in such notice (the “Final Closing Date”), their obligations under this Agreement to use commercially reasonable efforts to cause any remaining Managed Sites (including any Special Zoning Sites) to be converted to Lease Sites or Assignable Sites, as applicable; provided, however, that the T-Mobile Parties and the T-Mobile SPEs did not deliberately and knowingly cause the delay in the conversion of such Sites. Notwithstanding anything to the contrary contained in this Agreement, (i) the obligation of Crown and the Tower Operator to pay the Deferred Managed Site Consideration pursuant to Section 2.7(c) for any remaining Managed Sites that are subsequently converted to Lease Sites or Assignable Sites, as applicable, shall automatically and unconditionally terminate on the date that is 18 months after the date of this Agreement and (ii) from and after the Final Closing Date, Crown, Tower Operator or the Sale Site Subsidiaries or any other Affiliate of Crown may, in their respective discretion, continue any efforts, from time to time, to cause the conversion of any remaining Managed Sites to Lease Sites or Assignable Sites, as applicable, and the T-Mobile Parties and the T-Mobile SPEs shall provide Crown, Tower Operator or the Sale Site Subsidiaries, as applicable, with such reasonable assistance as may be reasonably requested by Crown, Tower Operator or the Sale Site Subsidiaries, as applicable, from time to time with respect thereto, including additional Technical Closings; provided, however, that the Tower Operator or Sale Site Subsidiaries, as applicable, shall reimburse the T-Mobile Contributor and the T-Mobile SPEs for their reasonable out-of-pocket costs and expenses related to providing such assistance after the Final Closing Date.

SECTION 2.8 Preparation of Closing Documents.

(a) The T-Mobile Parties shall prepare (using the information set forth in the Site List or the Updated Site List, as applicable) and, if applicable, notarize all the Collateral Agreements and all the exhibits to the Collateral Agreements (except for the Site Lease Agreements and Memorandum of Site Lease Agreements, which shall be prepared in accordance with Section 2.8(b)) for the Applicable Closing, in each case in form and substance reasonably satisfactory to Crown and, to the extent applicable, in form sufficient for recordation.

(b) The T-Mobile Parties shall use commercially reasonable efforts to prepare the Site Lease Agreement applicable to each of the Sites and the Memorandum of Site Lease Agreement applicable to each of the Lease Sites, in each case in form and substance reasonably satisfactory to Crown; provided, however, the execution and delivery of such Site Lease Agreements and Memoranda of Site Lease Agreements shall not be a condition to the Applicable Closing. To the extent any such Site Lease Agreements or the Memoranda of Site Lease Agreements are not completed at the Applicable Closing, the T-Mobile Parties shall execute and deliver same to the Tower Operator within 180 days following the Applicable Closing Date or as earlier specified in the MPL Site MLA or Sale Site MLA, as applicable. To the extent requested by the T-Mobile Contributors, the Tower Operator and Sale Site Subsidiaries shall use commercially reasonable efforts to assist the T-Mobile Parties in the preparation of the Site Lease Agreements and the Memoranda of Site Lease Agreements.

(c) If the public land records do not reflect the current T-Mobile Contributor as the named tenant of record under a Ground Lease (or the named owner of an Owned Site), and any Ground Lessor Estoppel or other documentation obtained or prepared in connection with the transactions contemplated hereby does not cure this condition, Crown shall notify the T-Mobile Contributors and the T-Mobile Parties shall provide Crown with such documentation as is reasonably necessary to correct the public land records with respect to such ownership (the “Confirmatory Assignments”). The T-Mobile Parties shall use commercially reasonable efforts to prepare all Confirmatory Assignments prior to the Applicable Closing; provided, however, that the execution and delivery of documentation with respect to the Confirmatory Assignments shall not be a condition to the Applicable Closing. To the extent that any Confirmatory Assignments required under the preceding sentence of this Section 2.8(c) are not completed by the Applicable Closing, the T-Mobile Parties shall execute and deliver such Confirmatory Assignments to the Tower Operator or the Sale Site Subsidiaries, as applicable, within 180 days following the Applicable Closing.

(d) At Crown’s request, the T-Mobile Parties shall use commercially reasonable efforts to prepare and record all intermediate assignments from the original lessee under a Ground Lease to the applicable T-Mobile Contributor that currently holds such Ground Lease that have not been recorded in the public land records (the “Corrective Assignments”), in each case in form and substance reasonably satisfactory to Crown and in form sufficient for recordation; provided, however, that the execution and recordation of such Confirmatory Assignments shall not be a condition to the Applicable Closing. To the extent requested by the T-Mobile Contributors, the Tower Operator and the Sale Site Subsidiaries, as applicable, shall use commercially reasonable efforts to assist the T-Mobile Parties in the preparation of the Corrective Assignments. The T-Mobile Contributors shall submit to the Tower Operator and the Sale Site Subsidiaries, as applicable, an invoice for, and the Tower Operator and the Sale Site Subsidiaries, as applicable, shall reimburse the T-Mobile Contributors for their reasonable out-of-pocket costs and expenses incurred in preparing any Corrective Assignments.

(e) If, prior to or after the applicable Closing, any Party identifies, in its reasonable judgment, any corrections to any Site Lease Agreement, Memorandum of Site Lease Agreement, Confirmatory Assignment, Corrective Assignment, Ground Lessor Estoppel, Non-Disturbance Agreement or other recorded document, such Party shall promptly notify the other Party and the Parties shall cooperate in good faith to effect an appropriate correction to that document and, if such document is a recorded document, to promptly record such corrected document in accordance with Section 2.10.

SECTION 2.9 Prorating of Expenses. Except as otherwise provided in the MPL and the MLAs, as of the Applicable Closing Date, prorations of receivables, payables, expenses, revenue and property or ad valorem Taxes relating to the use, occupancy and operation of the Included Property of the Sites shall be made on an accrual basis, with the T-Mobile Contributors being obligated to make any payments in respect of payables and expenses (including ground rent payments under Ground Leases), and being entitled to retain any receivables and revenue (including collocation revenue under Collocation Agreements and prepaid rent), in respect of events and for periods and portions thereof prior to the Applicable Closing Date, and the Tower Operator or the Sale Site Subsidiaries, as applicable, being obligated to make any payments in respect of payables and expenses (including ground rent payments under Ground Leases), and being entitled to receive any receivables and revenue (including collocation revenue under Collocation Agreements and prepaid rent), in respect of events and for periods and portions thereof on and subsequent to the Applicable Closing Date. The Parties shall use good faith efforts to determine and finalize any amounts due under this Section 2.9 prior to the Applicable Closing Date. The net amount of the prorations set forth in this Section 2.9 shall be credited to (or debited from) the Closing Total Consideration or the Subsequent Closing Total CA/NV Consideration payable by Crown at the Applicable Closing. For purposes of this Section 2.9, Taxes shall be accrued in accordance with Section 12.1(a)(iii).

SECTION 2.10 Recordation; Signage.

(a) The T-Mobile Parties and the T-Mobile SPEs acknowledge and agree that, from and after the Applicable Closing Date, Crown, the Tower Operator and the Sale Site Subsidiaries shall be permitted to record and, if necessary, re-record any documents (including any Site Lease Agreement, Memorandum of Site Lease Agreement, Corrective Assignment, Confirmatory Assignment, Ground Lessor Estoppel or Non-Disturbance Agreement) that are necessary or desirable to give effect to the transactions contemplated by this Agreement and the Collateral Agreements, in each case without any prior notice to or the prior consent of any T-Mobile Party or any T-Mobile SPE.

(b) Prior to the recordation or re-recordation of any document, to the extent reasonably practicable, the Tower Operator or Sale Site Subsidiaries, as applicable, shall cause a copy thereof to be delivered to T-Mobile, and the Tower Operator or Sale Site Subsidiaries, as applicable, shall further cause a copy of the recorded or re-recorded document to be delivered to T-Mobile promptly after recordation thereof.

(c) The Tower Operator and Sale Site Subsidiaries shall, from and after the Applicable Closing Date, have the right to place, at their sole cost and expense, signage on any Site to put third parties on notice of its interest in such Site, subject to compliance with applicable Laws and any Ground Lease applicable to such Site in question.

SECTION 2.11 Taxes; Bulk Sales.

(a) Taxes. Except as expressly provided in this Agreement, the MPL or the MLAs, the T-Mobile Contributors shall be responsible for and shall pay all Taxes to the extent attributable to the ownership of the Sites or the Included Property of the Sites by any T-Mobile Party, any T-Mobile SPE or any third party (other than Tower Operator, any Affiliate of Tower Operator, any direct or indirect transferee of Tower Operator or of any Affiliate of Tower Operator, or any Tower Subtenant), and the Tower Operator and Sale Site Subsidiaries shall be responsible for and shall pay all Taxes to the extent attributable to the possession or operation of the Sites or the Included Property of the Sites or the ownership, possession or operation of any assets on the Sites by any Person described in the immediately preceding parenthetical clause. For the avoidance of doubt, except as expressly set forth in the MPL or the MLAs, each Party shall be responsible for Taxes imposed on its own income and no Party shall be entitled to indemnification for Taxes imposed on income.

(b) Payments. Crown agrees that the payments contemplated by Article 3 to be made by Crown are non-refundable and that Crown shall not have any right of abatement, reduction, setoff, counterclaim, rescission, recoupment, refund, defense or deduction with respect thereto, including in connection with any event of default by the T-Mobile Parties, the T-Mobile SPEs or their respective Affiliates or any casualty or condemnation, in each case except as otherwise contemplated by this Agreement or the Collateral Agreements.

(c) Bulk Sales. Crown and the T-Mobile Contributors hereby waive compliance by Crown and the T-Mobile Contributors with the provisions of the “bulk sales,” “bulk transfer” and similar Laws; provided, however, that such waiver is not intended to preclude the T-Mobile Contributors from claiming bulk sale or bulk transfer treatment on the transfer of the assets to the T-Mobile SPEs and Sale Site Subsidiaries.

(d) Tax Cooperation. The Parties will furnish or cause to be furnished to each other, upon request, as promptly as practicable, such information and assistance relating to the Sale Site Subsidiaries and Included Property transferred pursuant to this Agreement (including access to books and records) as is reasonably necessary for the filing of all Tax Returns, the making of any election relating to Taxes, the preparation for any audit by any Taxing authority, and the prosecution or defense of any Claims relating to any Tax. Any expenses incurred in furnishing such information or assistance will be borne by the Party requesting it.

(e) Income Tax Treatment. It is intended that, solely for United States federal (and other applicable) income Tax purposes, Crown will be treated as purchasing the Sale Sites (or, as applicable, the interests in the Sale Sites held by the T-Mobile Contributors and the T-Mobile SPEs) pursuant to this Agreement on the Applicable Closing Date, and each of Crown, T-Mobile and their Affiliates will file all Tax Returns consistent with such treatment. Each of the Parties agrees that it shall (i) be bound by the allocation of the consideration set forth in Section 2.11(g) of this Agreement and Exhibits C and D of the MPL for purposes of determining Taxes (but not for any other purpose), (ii) prepare and file, and cause its Affiliates to prepare and file, its Tax Returns on a basis consistent with such allocation, and (iii) take no position, and cause its Affiliates to take no position, inconsistent with such allocation on any applicable Tax Return, except as otherwise required by Law or an Order. If such allocation is disputed by any Governmental Authority with taxing authority, the Party receiving notice of such dispute shall promptly notify the other Parties of such dispute.

(f) Transfer Taxes. All Transfer Taxes imposed as a result of the sale of the Sale Sites (or, as applicable, the interests in the Sale Sites held by the T-Mobile Contributors and the T-Mobile SPEs) pursuant to this Agreement shall be borne equally by the T-Mobile Contributors, on the one hand, and Tower Operator, on the other hand. Such Transfer Taxes shall be governed by the rules and procedures set forth in Section 22(e) of the MPL (substituting references to “T-Mobile Contributors” in place of references to “T-Mobile Lessors”).

(g) Tax Allocations. Subject to Section 1.3, Section 2.9 and Article 3, the parties agree that the purchase price for the Sites shall be allocated among the groups of Sites for U.S. federal, state and local income tax purposes in accordance with the following principles:

(i) the aggregate amount payable by Crown for Sites other than CA/NV Sites shall be the sum of the Final Lease Site Rent for each MPL Site that is a Lease Site (but not a CA/NV Site) on the Applicable Closing Date, the Final Assignable Price for each Sale Site that is an Assignable Site (but not a CA/NV Site) as of the Applicable Closing Date, and the Final Managed Site Consideration for each MPL Site or Sale Site that is a Managed Site (but not a CA/NV Site) as of the Applicable Closing Date (and, if and to the extent it becomes due and payable hereunder, the Deferred Managed Site Consideration for any such Managed Site (assuming the Final Total TCF for such Site has been determined) that becomes a Lease Site or an Assignable Site in accordance with the terms of this Agreement);

(ii) the aggregate amount referred to in clause (i) shall be allocated among each of the 15 Tranches of Sites (as defined in the MPL) and the Sale Sites (other than CA/NV Sites) in accordance with an appraisal by Deloitte LLP of the aggregate value of the Sites in each of such 16 categories;

(iii) if the CA/NV Inclusion occurs at a Subsequent CA/NV Closing, the aggregate amount allocated to the CA/NV Sites shall be the Subsequent Closing Total CA/NV Consideration;

(iv) if the CA/NV Inclusion occurs at the Initial Closing, then (1) Deloitte LLP shall provide an appraisal of value of the CA/NV Sites, (2) such appraised value for the CA/NV Sites shall be allocated to the CA/NV Sites, and (3) to the extent the amount actually paid by Crown for such CA/NV Sites under the formula that would have applied to such Sites under clause (i) if they had not been CA/NV Sites exceeds the amount of such appraisal (the “Excess Payment”), such Excess Payment shall not be allocated to the purchase price of any Sites, and (4) a portion of the “T-Mobile Total Rent Amount” payable under the MPL Site MLA and the “T-Mobile Collocation Rent” payable under the Sale Site MLA (based on the excess of $1,905 over $1,850 per Site) having a discounted present value of the Excess Payment shall be treated as a repayment of the Excess Payment and interest thereon consistent with applicable U.S. federal income tax principles; the parties acknowledge that the amount of the Excess Payment is expected to be approximately $100,000,000; and

(v) the aggregate consideration payable for the Sites shall equal the sum of the consideration so payable with respect to each Site or tranche of Sites as set forth in Section 2.11(g)(i) through (iv) above, as applicable.

SECTION 2.12 Integrated Transactions. The Parties acknowledge and agree that: (i) the transactions contemplated by this Agreement and the Collateral Agreements are dependent upon one another, (ii) the Parties would not have entered into this Agreement and the Collateral Agreements unless this Agreement and all of the Collateral Agreements were being entered into as and when contemplated and (iii) this Agreement and the Collateral Agreements are to be treated as a single integrated and indivisible agreement for all purposes, including the Bankruptcy of any Party.

provided, however, that if the CA/NV Inclusion does not occur at the Initial Closing, the CA/NV Sites shall be excluded from the definitions of Closing Lease Site Rent, Closing Assignable Site Price, Closing Managed Site Consideration and Closing Total Consideration and for purposes of all calculations and payments made pursuant to or under this Section 3.2.

SECTION 3.3 Final Total TCF Determination.

(a) Within 180 calendar days after the Initial Closing Date, Crown shall deliver to T-Mobile a statement (the “Crown Site Report”) that shall set forth (i) its calculation of the TCF and Supplemental TCF for each Portfolio Site as of the Applicable Closing Date (with respect to each such Portfolio Site, the “Crown Proposed TCF”) and (ii) subject to Section 4.4, its Site Designation (the “Crown Proposed Site Designation”) of each Portfolio Site as of the Applicable Closing Date, together with a list of all Portfolio Sites as to which Crown disputes the applicable Site Designation as set forth in the Updated Site List (which shall contain a reasonably detailed description of such dispute). To facilitate the preparation of the Crown Site Report by Crown, the T-Mobile Parties shall promptly provide Crown with such documentation and information and access to such employees, officers and professionals of the T-Mobile Parties and their respective Affiliates as Crown may reasonably request in order to complete the Crown Site Report.

(b) The Crown Site Report shall become final and binding upon the Parties with respect to each Portfolio Site, and (i) the Crown Proposed TCF shall become the Final Total TCF for such Portfolio Site and (ii) the Crown Proposed Site Designation shall become the Final Site Designation for such Portfolio Site, on the 30th calendar day following the delivery of the Crown Site Report, unless T-Mobile objects to the Crown Proposed TCF or the Crown Proposed Site Designation for such Portfolio Site in writing prior to such date. For each Portfolio Site for which no dispute exists, Crown and T-Mobile shall execute a certificate that sets forth the Crown Proposed Site Designation of such Portfolio Site (which shall be the Final Site Designation of such Portfolio Site) and the amount of the agreed or undisputed TCF and Supplemental TCF for such Portfolio Site (which shall be the Final Total TCF for such Portfolio Site). For any Portfolio Site for which a dispute exists and for which T-Mobile has provided a timely written notice, the Final Total TCF or the Final Site Designation for such Portfolio Site shall be determined in accordance with Section 3.3(c).

(c) To the extent that T-Mobile and Crown are unable to resolve all disagreements they may have regarding the Site Designation of any Portfolio Site or the TCF and Supplemental TCF for any Portfolio Site, then any such disagreements shall promptly be submitted to the Settlement Firm for resolution and the Settlement Firm shall determine the Final Site Designation of any such Portfolio Sites and the Final Total TCF for any such Portfolio Sites (in each case, as of the Applicable Closing Date). Crown and the T-Mobile Parties shall cooperate with the Settlement Firm and shall proceed reasonably and in good faith to cause the Settlement Firm to resolve any such disagreements not later than 30 calendar days after the engagement of the Settlement Firm. 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 shall determine the Final Total TCF for any such Portfolio Site using only: (i) the definition of TCF and Supplemental TCF in this Agreement (and related provisions herein) and the information set forth in each Included Collocation Agreement and Ground Lease for such Portfolio Site, and (ii) the amounts, rates and terms under each Included Collocation Agreement and Ground Lease for such Portfolio Site in effect as of the Applicable Closing Date; to the extent that rent is paid or payable on an other-than-monthly basis, rent for the month shall include an apportioned amount of such rent attributable to such month. The Settlement Firm’s resolution of the disagreement shall be reflected in a written report (the “Settlement Firm Site 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 Final Total TCF or Final Site Designation for each such Portfolio Site. 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.

(b) In furtherance of the foregoing, and notwithstanding anything to the contrary contained in this Agreement, the T-Mobile Parties and the T-Mobile SPEs shall be responsible for reimbursing, and shall promptly, but in any event no later than 10 business days following request therefor, reimburse, Crown, the Tower Operator and, after the Initial Closing, the applicable Sale Site Subsidiary for all costs and expenses incurred by any of them in connection with any Non-Compliant Site, including any actions taken by Crown, the Tower Operator or, after the Initial Closing, the applicable Sale Site Subsidiary pursuant to Section 3.5(a).

SECTION 3.6 Exclusive Remedy. Subject to Section 1.3, Section 2.7(c), Section 2.9, Section 4.4, Section 4.8 and Section 4.9, each Party’s sole and exclusive remedy for any matters relating to Site Designations and the calculation of TCF, Supplemental TCF, Closing Total Consideration, Subsequent Closing Total CA/NV Consideration, Final Total Consideration is set forth in this Article 3, and the Parties hereby acknowledge and agree that they are not entitled to, and expressly waive, any and all other rights and remedies that the Parties may have (including under Article 12) relating to Site Designation and the calculation of TCF, Supplemental TCF, Closing Total Consideration, Subsequent Closing Total CA/NV Consideration and Final Total Consideration.

ARTICLE 4

OTHER PROCEDURES FOR SITES

SECTION 4.1 Contributable Sites; Lease Sites; Assignable Sites.

(a) If (i) there are no Contribution Exceptions with respect to an MPL Site or (ii) all of the Contribution Exceptions with respect to an MPL Site have been corrected or addressed pursuant to Section 4.2 or Section 4.3, then, except as otherwise provided in this Article 4, such Site shall thereafter be deemed to be a “Contributable Site”; provided, however, that a Special Zoning Site shall not be deemed a Contributable Site.

(b) With respect to each Contributable Site, if (i) there are no Leasing Exceptions with respect to such Site or (ii) all of the Leasing Exceptions with respect to such Site have been corrected or addressed pursuant to Section 4.2 or Section 4.3, then, except as otherwise provided in this Article 4, such Site shall thereafter be deemed to be a “Lease Site”.

(c) If (i) there are no Assignment Exceptions with respect to a Sale Site or (ii) all of the Assignment Exceptions with respect to a Sale Site have been corrected or addressed pursuant to Section 4.2 or Section 4.3 (including, with respect to the CA/NV Sites, the CA/NV Consent and Acknowledgment has been received by Crown), then, except as otherwise provided in this Article 4, such Site will thereafter be deemed to be an “Assignable Site”; provided, however, that a Special Zoning Site shall not be deemed an Assignable Site.

SECTION 4.2 Certain Procedures with Respect to Identifying and Curing Exceptions.

(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).

T-MOBILE PARTIES

Each T-Mobile Party represents and warrants to Crown and the Tower Operator as follows:

SECTION 5.1 Organization.

(a) Each T-Mobile Party is a corporation or other entity duly organized, validly existing and in good standing under the laws of the state of its organization with the requisite corporate or other power and authority to carry on its business (including the ownership, lease and operation of the Included Property of the Sites) as it is now being conducted and is duly qualified and in good standing as a foreign entity in each jurisdiction in which the character of the Included Property owned, leased or operated by it requires such qualification, except for such qualifications the failure of which to obtain, individually or in the aggregate, has not had and would not reasonably be expected to have a Material Adverse Effect. Each T-Mobile Contributor and T-Mobile SPE is a wholly owned Subsidiary of T-Mobile.

(b) At the Initial Closing, each T-Mobile SPE and Sale Site Subsidiary shall be a limited liability company duly organized, validly existing and in good standing under the laws of the state of Delaware with the requisite limited liability power and authority to carry on its business (including, if applicable, the ownership, lease and operation of the Included Property of the Sites) as shall be conducted at the Initial Closing, and shall be duly qualified and in good standing as a foreign entity in each jurisdiction in which the character of the Included Property that shall be owned, leased or operated by it requires such qualification (or applications for such qualification shall have been filed), except for such qualifications (or filing of applications to qualify) the failure of which to obtain or file, individually or in the aggregate, has not had and would not reasonably be expected to have a Material Adverse Effect.

SECTION 9.15 Tower Bonds. Unless and until the Tower Operator has exercised its purchase option under the MPL with respect to any MPL Site, the applicable T-Mobile SPE shall maintain or replace all Tower Bonds that are in existence as of the Initial Closing Date with respect to such MPL Site (and provide the Tower Operator copies of same), unless any such Tower Bond is no longer required with respect to such Site. Unless and until any Non-Assignable Site is converted to an Assignable Site and a Technical Closing with respect to such Site is held in accordance with Section 2.7, the applicable T-Mobile Party shall maintain or replace all Tower Bonds that are in existence as of the Applicable Closing Date with respect to such Site (and provide the Sale Site Subsidiaries (or their designees) copies of same), unless any such Tower Bond is no longer required with respect to such Site. With respect to any Sale Site, no later than the date which is six months following the Applicable Closing Date in the case of an Assignable Site, or six months following the applicable Technical Closing Date in the case of any Non-Assignable converted to an Assignable Site, the applicable Sale Site Subsidiary shall, at its own cost and expense, (i) cause all Tower Bonds with respect to such Assignable Site to be replaced and, to the extent applicable, terminated and discharged (including when any such Tower Bond expires or becomes subject to renewal during such six-month period), and (ii) cause all funds, property or other collateral related to such Tower Bonds that are actually received by such Sale Site Subsidiary to be promptly returned and paid to T-Mobile Contributors.

When delivered, the Required Financial Statements shall present fairly in all material respects the results of operations of the Sites on a combined consolidated basis for the periods indicated, in conformity with GAAP consistently applied except as noted in the Required Financial Statements. Prior to the Initial Closing Date, the T-Mobile Parties shall use commercially reasonable efforts to cause the independent registered public accounting firm that completed the audit of the Required Financial Statements to provide a written consent to the inclusion of its audit report in appropriate filings by Crown or the Tower Operator with the SEC. As soon as practicable upon request of Crown (but in any event within 40 days after the end of each fiscal quarter), T-Mobile Parties shall deliver to Crown an unaudited combined consolidated income statement for the Sites for the prior stub period(s); provided that the T-Mobile Parties shall have no obligation to deliver any such stub period statements for periods beginning after the Applicable Closing Date. The out-of-pocket costs and expenses of preparing the Required Financial Statements and subsequent stub period updates thereof shall be shared equally between Crown and the T-Mobile Parties.

If the sale, conveyance, assignment, transfer and delivery of any CA/NV Site cannot be effected without the Authorization or consent of a third-party, T-Mobile and the applicable T-Mobile Parties shall, and shall cause their respective Affiliates to, use their commercially reasonable efforts to obtain all such Authorizations and consents. Until such time as all such Authorizations and consents are obtained and such CA/NV Site is sold, conveyed, assigned, transferred and delivered to Crown (or its designee), such CA/NV Site shall remain subject to the Management Agreement. Upon the exercise of any option to purchase any CA/NV Site in accordance with this Section 9.17, concurrently with CA/NV Counterparty’s sale, conveyance, assignment, transfer and delivery of such CA/NV Site to the T-Mobile Parties or Crown (or its designee), Crown (or its designee) shall pay the CA/NV Counterparty, on behalf of T-Mobile and its Affiliates, the purchase price for the exercise of such option to purchase.

SECTION 12.3 Indemnification Claim Procedure.

(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 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.

(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.

SECTION 12.6 Exclusive Remedies. After the Initial Closing, except with respect to fraud by or on behalf of the Indemnifying Party and except as expressly provided in Article 3 and Section 1.3, Section 2.7(c), Section 2.9, Section 4.4, Section 4.8 and Section 4.9, the Parties acknowledge and agree that the indemnification provisions of Section 2.11 and this Article 12 shall be the sole and exclusive monetary remedy for any breach of or inaccuracy in any representation, warranty or covenant of the Parties contained in this Agreement. Notwithstanding the foregoing, nothing contained herein shall impair the right of Crown and the Tower Operator to compel, at any time, specific performance by any T-Mobile Party or any T-Mobile SPE of its obligations under this Agreement or any of the Collateral Agreements or the right of the T-Mobile Parties and the T-Mobile SPEs to compel, after the Initial Closing, specific performance by Crown or the Tower Operator of its obligations under this Agreement or any of the Collateral Agreements that survive the Initial Closing.

All payments made pursuant to this Article 12 shall, to the fullest extent permitted by applicable Law, be treated for all Tax purposes (to the extent such treatment is consistent with the rent allocations made for purposes of Section 467 of the Code pursuant to Section 12 of the MPL) as adjustments to the Final Total Consideration. The amount of any indemnified Claim under this Article 12 shall take into account (i) any amounts actually recovered by the Indemnified Party pursuant to any indemnification by, or indemnification agreement with, any third-party, (ii) any insurance proceeds or other cash receipts or sources of reimbursement actually collected by the Indemnified Party in connection with the Claim, (iii) any Tax benefits actually realized or realizable in the year of the loss or the following taxable year by the Indemnified Party in connection with such Claims and the recovery thereof and (iv) any Tax costs actually incurred or to be incurred in the year of receipt of the indemnity payment hereunder or the following taxable year by the Indemnified Party in connection with such Claims and the recovery thereof. Any amount paid by the Indemnifying Party for an indemnified Claim that is in excess of the amount owed after applying the netting amounts described above shall be reimbursed promptly by the Indemnified Party.

ARTICLE 13

TERMINATION

SECTION 13.1 Termination of Agreement. This Agreement may be terminated and the transactions contemplated by this Agreement may be abandoned at any time prior to the Initial Closing Date:

(a) By mutual written consent of the T-Mobile Parties and Crown;

(b) By the T-Mobile Parties or Crown, if the Initial Closing shall not have occurred on or prior to the day that is 180 days after the date of this Agreement so long as the terminating Party has not breached any of its obligations under this Agreement that result in a substantial delay to, or preventing, the Initial Closing; provided that neither party shall have the right to terminate this Agreement pursuant to this Section 13.1(b) prior to the date that is 270 days after the date of this Agreement if the principal reason the Initial Closing has not occurred on or prior to the day that is 180 days after the date of this Agreement is the failure of the conditions to Closing set forth in Section 10.2 or Section 11.2 to be satisfied.

(c) 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 Crown or the Tower Operator (i) fails in any material respect to perform any of its covenants under this Agreement when performance is due or (ii) has breached in any material respect any of the representations or warranties contained in Article 7 or Article 8 of this Agreement and, in each case, such failure or breach has not been cured within 30 days after the T-Mobile Contributors deliver written notice thereof;

(d) By Crown; provided that Crown and the Tower Operator are not then in material breach of any of their obligations under this Agreement, if the T-Mobile Parties, the T-Mobile SPEs or the Sale Site Subsidiaries (i) fail in any material respect to perform any of their covenants under this Agreement when performance is due or (ii) have breached in any material respect any of the representations and warranties contained in Article 5 or Article 6 of this Agreement, and in each case, such failure or breach has not been cured within 30 days after Crown delivers written notice thereof;

(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.

SECTION 14.6 Assignment; Successors and Assigns; Third-Party Beneficiaries. This Agreement shall not be assignable by any Party without the express prior written consent of the other Parties and any such assignment shall be null and void, except that (i) each of the Parties may assign all or a portion of its rights and remedies (but none of its obligations) under this Agreement to one or more of its respective Affiliates, including any special purpose entity formed in connection with the transactions contemplated by this Agreement and (ii) Crown, the Tower Operator and, after the Initial Closing, the Sale Site Subsidiaries may assign all or any portion of their rights and remedies to its lenders. This Agreement shall be binding upon and inure solely to the benefit of each Party and its successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, except for Section 12.1, which is intended to benefit and may be enforced by any of the Crown Indemnified Parties and Section 12.2, which is intended to benefit and may be enforced by any of the T-Mobile Indemnified Parties.

SECTION 14.7 Amendment. This Agreement may be amended, modified or supplemented only by written agreement of the Parties.

SECTION 14.8 Time of 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.

SECTION 14.9 Specific Performance. Each Party recognizes and agrees that, in the event of any failure or refusal by any Party to perform its obligations required by this Agreement, remedies at law would be inadequate, and that in addition to such other remedies as may be available to it at Law, in equity or pursuant to this Agreement, each Party may seek injunctive relief and may enforce its rights under, and the terms and provisions of, this Agreement by an action for specific performance to the 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. Notwithstanding the foregoing, each Party acknowledges and agrees that, prior to the Initial Closing, none of the T-Mobile Parties, the T-Mobile SPEs or the Sale Site Subsidiaries shall be entitled to seek injunctive relief to prevent breaches of this Agreement or seek to enforce specifically its rights under, or the terms and provisions of, this Agreement by an action for specific performance, and that the sole and exclusive remedy available to any T-Mobile Party, T-Mobile SPE or Sale Site Subsidiary 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 shall be the Termination Fee set forth in Section 13.3 (which fee is only payable in the event this Agreement is terminated pursuant to Section 13.1(f)).

SECTION 14.10 Limitation of Liability. Notwithstanding anything in this Agreement or the Collateral Agreements to the contrary, no Party shall be liable to any other Party for indirect, incidental, special or consequential damages, loss of anticipated profits or punitive damages that arise out of or relate to this Agreement or the performance or breach hereof or any liability retained or assumed hereunder, in each case except as may be payable to a claimant in a Third Party Claim and provided that the foregoing shall not limit recovery for diminution in value of an asset as a result of a breach.

SECTION 14.11 Disclosures. Disclosure of any fact or item in the T-Mobile Disclosure Letter or Crown Disclosure Letter, by reference to a particular Article or Section in this Agreement shall, should the existence of the fact or item be reasonably apparent on its face to relate to any other Article or Section of this Agreement, be deemed to be disclosed with respect to such other Article or Section of this Agreement to which it relates.

SECTION 14.12 Jurisdiction. Subject to Section 3.3 and Section 4.4, in connection with any suit, action or proceeding (an “Action”) arising out of or relating to this Agreement, each of the Parties:

(a) Submits to the exclusive jurisdiction of the Courts of the State of New York sitting in the County of New York, the court of the United States of America for the Southern District of New York and appellate courts having jurisdiction of appeals from any of the foregoing, and agrees that all Actions hereunder shall be heard and determined in such New York State court or, to the extent permitted by Law, in such federal court;

(b) Consents that any such Actions may and shall be brought in such courts and waives any objection that it may now or hereafter have to the venue or jurisdiction of any such Action in any such court or that such Action was brought in an inconvenient court and agrees not to plead or claim the same; and

(c) 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.

SECTION 14.13 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.

SECTION 14.14 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.
