        (c) the mutual agreement of the Parties;

      provided that such termination shall be automatically effective, without requirement of further
        action by the Company, the Manager or the Independent Directors (including any notice requirement under Section 10 of the Management Services Agreement) upon the later to occur of (x) ten (10) calendar days following the occurrence of the QTE and
        (y) payment to the Manager of all of the following: (i) all accrued and unpaid Base Management Fees (including $8,500,000 of fees waived in accordance with that certain waiver letter issued by the Manager dated October 30, 2018 (as it may be
        amended, the “Waiver Letter”, and such amount, the “Waived Fees”)) and Performance Fees for the period prior to the
        effectiveness of such termination; (ii) all applicable Disposition Payments, including, if applicable, in respect of the Disposition that constituted the QTE; (iii) the Additional Payment, if any; and (iv) the Make-Whole Amount, if any (such date
        on which such termination takes effect, the “Termination Date”). If the Management Services Agreement is terminated in accordance with this Section 2.1, the Parties hereby agree that no
        Termination Fee shall be due and payable, and the Manager hereby waives any right thereto under the Management Services Agreement.  If the Management Services Agreement has not been terminated prior to the sixth (6th) anniversary of the
        date hereof, the Manager and the Independent Directors will engage in reasonable, good faith discussions regarding a potential internalization or other framework for a termination of the Management Services Agreement.

      Section 2.2   Effect of Termination.  In the event of a termination of the Management Services Agreement pursuant to this Agreement (as opposed to a termination pursuant to Article X of the
          Management Services Agreement), the provisions of Sections 10.3, 10.4 and 10.5 of the Management Services Agreement shall be observed in all respects.  For the avoidance of doubt, Section 10.1(b) of the Management Services Agreement shall not
          apply in the event of a Delisting Event (as defined therein) during the term of this Agreement.

      Section 2.3   Agreement to Bind Subsidiaries. The Company covenants and agrees to cause any Managed Subsidiary created or acquired after the date of this Agreement that executes a counterpart
          to the Management Services Agreement to execute a counterpart of this Agreement agreeing to be bound by the terms hereunder simultaneously with its execution of the counterpart to the Management Services Agreement.

      Section 2.4   Effect of Dispositions.  Upon consummation of a Disposition, the Management Services Agreement shall no longer apply to the equity interests or assets of the Company or its
          Subsidiaries that were disposed of in such Disposition.

      Section 3.1   Disposition Payments.  Upon any Disposition and upon the receipt of any delayed payments of consideration with respect to any Disposition, the Company and MIC Ohana shall pay to
          the Manager the applicable payment, if any, in connection with such Disposition (each, a “Disposition Payment”) as set forth herein.  Any such Disposition Payment shall become due and
          payable, and the Company and MIC Ohana shall pay any such Disposition Payment, to the Manager on the third (3rd) Business Day following the consummation of the applicable Disposition transaction (or receipt of any delayed payment),
          unless any Disposition Payment is in relation to Proceeds related to a Spin-Off in which case the Disposition Payment shall be due and payable within thirty-five (35) trading days from such Disposition, and, in each case, subject to the
          completion of any valuation process commenced in accordance with Section 3.4 and the resolution of any dispute with respect to the Payment Report delivered in accordance with Section 3.7; provided further that no Disposition Payments shall be
          required to be paid to the Manager pursuant to this Section 3.1 until the consummation of the Disposition transaction after giving effect to which the Cumulative Proceeds exceed $750 million (the “Minimum Amount”), at which time the Disposition Payment for such Disposition transaction and all prior Dispositions for which a Disposition Payment was not paid pursuant this proviso shall become due and payable to the Manager
          in accordance with the terms of Sections 3.2, 3.7 and, if applicable, 3.4.  All Disposition Payments shall be paid (i) in cash in any Disposition in which the Proceeds are received directly by the Company shareholders in cash or in which the
          Proceeds are received directly by the Company or its Subsidiary in cash and (ii) in the same form of consideration received (a) by the Company shareholders in any Disposition in which the Proceeds are received directly by or distributed to the
          Company Shareholders in a form other than cash or (b) by the Company or its Subsidiary in any Disposition in which the Proceeds are received directly by the Company or one of its Subsidiaries in a form other than cash prior to distribution of any
          Proceeds to the Company shareholders (provided that the Independent Directors may elect to make any such Disposition Payment in cash in lieu of the same form of consideration received by the Company or its Subsidiary by notice of such election to
          the Manager at least thirteen (13) Business Days prior to the consummation of such Disposition); provided that, if the Company or its Subsidiary receives consideration in the form of securities for which the Company or such Subsidiary receives
          registration rights and the Company elects to make the Disposition Payment in the form of such securities, then the Manager shall receive registration rights in respect of such securities comprising the Disposition Payment substantially similar
          to those received by the Company or its Subsidiary, as applicable; provided further that, in the event of a Spin-Off, the Manager shall have the right to elect, by notice of such election to the Company no later than the twenty-fifth (25th)
          trading day immediately following the consummation of the Spin-Off, to cause the Disposition Payment to be made (A) in cash or (B) in the same form as the equity share capital distributed to the holders of Company Common Stock as a class, but,
          with respect to clause (B), only if payment of the Disposition Payment in such form would not cause the Company’s nationally recognized external legal counsel to be unable to issue a “should” level of written opinion with respect to the
          Spin-Off’s qualification as a tax-free distribution under Section 355 of the Code or otherwise result in a tax liability to the Company that has a material adverse effect on the Company (provided that the Company shall use reasonable best efforts
          to structure the Spin-Off such that payment of the Disposition Payment in such form would not cause the Company’s nationally recognized external legal counsel to be unable to issue a “should” level of written opinion with respect to the
          Spin-Off’s qualification as a tax-free distribution under Section 355 of the Code).  In connection with a Spin-Off, the Company shall (x) cause SpinCo to issue and transfer SpinCo Stock to the Manager to the extent and as contemplated by this
          Agreement, and to take all other actions with respect to SpinCo Stock as contemplated by this Agreement, and (y) cause the agreements with SpinCo with respect to the Spin-Off to contain provisions that (1) require SpinCo to issue and transfer
          SpinCo Stock to the Manager to the extent and as contemplated by this Agreement, and to take all other actions with respect to SpinCo Stock as contemplated by this Agreement, and (2) provide that the Manager is a third party beneficiary of such
          agreements with a right to enforce the provisions contemplated by clause (1).

      Section 3.2   Calculation of Disposition Payments.  The Disposition Payment for any particular Disposition prior to a QTE shall be equal to the difference between (a) the aggregate Disposition
          Payment Amount for all Dispositions inclusive of such Disposition as determined under the calculations set forth on Exhibit A hereto (with respect to any such Disposition, the “Cumulative
            Disposition Payment Amount”) and (b) the total Disposition Payments paid to the Manager prior to such Disposition pursuant to this Agreement. Notwithstanding the foregoing, in the event of a QTE, the Cumulative Disposition Payment Amount
          shall be deemed to be equal to the greater of (x) the amount determined under the calculations set forth on Exhibit A hereto, and (y) the sum of (i) $50 million plus (ii) 1.5% multiplied by Cumulative Proceeds in excess of $500 million.

      Section 3.3   Transaction Structuring.  The Company agrees that neither it nor its Subsidiaries shall take (or omit to take) any action with the intent of avoiding or reducing the payment of a
          Disposition Payment in connection with a Disposition.  A Disposition Payment will be payable, based on the same calculations described above (as equitably applied to the subject transaction or event), with respect to the proceeds of any other
          transaction or event pursuant to which cash is distributed to holders of Company Common Stock which is structured with the intent of avoiding or reducing the payment of a Disposition Payment hereunder.

      Section 3.4   Determination of Fair Market Value.  To the extent the consideration in a Disposition is in a form other than as provided in clauses (a) – (d) of the definition of “Base Amount”,
          the Fair Market Value of such consideration shall be determined pursuant to this Section 3.4.  The Manager and the Independent Directors shall negotiate in good faith to determine the Fair Market Value of such consideration prior to the
          consummation of the applicable Disposition.  If they are unable to agree on such Fair Market Value by the date of consummation of such Disposition, then the Manager or the Independent Directors may commence the valuation process described in this
          Section 3.4 by providing written notice to the other Parties no later than ten (10) Business Days after the consummation of the applicable Disposition (such notice, a “Valuation Process Notice”).
          In the event a Valuation Process Notice is delivered, then within ten (10) Business Days of the delivery of the Valuation Process Notice, each of the Manager, on the one hand, and the Independent Directors, on the other hand, shall appoint an
          internationally recognized valuation firm (an “Appointed Bank”). Each of the Manager, on the one hand, and the Company and the Managed Subsidiaries, on the other hand, shall instruct its
          Appointed Bank to determine, by no later than twenty (20) Business Days after being appointed, its best estimate of the Fair Market Value of such consideration, based on the customary methodologies that such Appointed Bank in its professional
          experience deems relevant to such a determination. On the forty-fifth (45th) Business Day following delivery of the Valuation Process Notice or such earlier date as agreed to by the Parties, each Appointed Bank shall present to the
          Parties and the other Appointed Bank its determination of the Fair Market Value of such consideration. In the event the Fair Market Values determined by the two Appointed Banks are within ten percent (10%) of one another (determined by reference
          to the higher of the two), the Fair Market Value shall be the average of those two estimates and such determination of the Fair Market Value of the consideration shall be final and binding on the Parties. In the event the Fair Market Values
          determined by the two Appointed Banks are not within ten percent (10%) of one another (determined by reference to the higher of the two), the Appointed Banks shall mutually select a third internationally recognized valuation firm (the “Independent Bank”) to determine, by no later than twenty (20) Business Days after being appointed, which of the two estimates of the Fair Market Value of the consideration prepared by the
          Appointed Banks most closely approximates the Fair Market Value of the consideration based on the customary methodologies that such Independent Bank in its professional experience deems relevant to such a determination, which estimate shall be
          deemed to be the Fair Market Value of the consideration and shall be final and binding on the Parties.  The fees and expenses of the Appointed Banks and the Independent Bank shall be borne by the Party (either the Company or the Manager) whose
          calculation of the applicable Fair Market Value is furthest from the amount determined pursuant to this Section 3.4 (and, for the avoidance of doubt, in no case shall any such fees borne by the Company be included in the calculation of Company
          Transaction Costs).  Within five (5) Business Days of the final determination of the Fair Market Value of such consideration, the Disposition Payment with respect to such Disposition shall be calculated and, subject to Section 3.7, the Company
          and MIC Ohana shall pay to the Manager the amount of the Disposition Payment payable with respect to such Disposition.

      Section 3.5   Additional Payment.  If a QTE contemplated by Section 2.1(a) or Section 2.1(b) herein occurs on or prior to January 1, 2022, the Company shall pay the Manager $25 million in cash
          concurrently with payment of the Disposition Payment in respect of the Disposition that resulted in the QTE (such payment, the “Additional Payment”); provided that for purposes of this
          Section 3.5, if on January 1, 2022, one or more definitive agreements with respect to a QTE have been executed, or a regulatory application with respect to a QTE has been filed, but the transactions effecting such QTE are pending and have not yet
          been consummated, such date shall be extended to July 1, 2022.

      Section 3.6   Make-Whole Amount.  The Company shall pay the Manager the Make-Whole Amount, if any, in cash concurrently with the consummation of the Disposition that resulted in a QTE
          contemplated by Section 2.1(a) or Section 2.1(b) herein.

      Section 3.7   Consultation on Calculations. No later than the later of ten (10) Business Days prior to (x) the consummation of a Disposition and (y) the date on which a Disposition Payment
          under this Agreement is due, the Manager will prepare and furnish to the Independent Directors, a report detailing the calculation of the applicable Disposition Payment (the “Payment Report”).
          If the Independent Directors, in good faith and after consultation with legal and financial advisors as necessary or appropriate, asserts that the Payment Report does not accurately reflect the information and calculations required pursuant to
          this Agreement or that the underlying information used by the Manager to produce, or that is reflected on or subsumed in, the Payment Report is inaccurate or incomplete, then the Independent Directors shall notify the Manager not more than twenty
          (20) Business Days after the Independent Directors have received the applicable Payment Report from the Manager (provided that, for the avoidance of doubt, if the Independent Directors fail to notify the Manager in writing within such twenty (20)
          Business Day period, the Company shall be obligated to make the payment due on the twenty-first (21st) Business Day after the Independent Directors have received the applicable Payment Report from the Manager), and, in such event, the
          Company, the Independent Directors and the Manager shall consider the issues raised or in dispute and discuss such issues with each other and attempt to reach a mutually satisfactory agreement.  Until the payment of any Disposition Fee with
          respect to a Disposition, the Company shall, on the date of the consummation of the applicable Disposition transaction (or, with respect to a Spin-Off, on the date that is five (5) trading days after the Manager makes its election contemplated by
          the last sentence of Section 3.1 and, in any event, no later than the thirtieth (30th) trading day after the consummation of the Spin-Off), place consideration equal to any unpaid Disposition Fee shown as due in the applicable Payment
          Report in escrow with a nationally recognized financial institution mutually agreed upon by the Manager and the Independent Directors pursuant to an escrow agreement on customary market terms (with such escrow agreement as reasonably acceptable
          to the Manager and the Independent Directors), with such amounts to be released to the Company or the Manager only upon determination of the Disposition Fee in accordance with this Section 3.7.  Thereafter, the Independent Directors and the
          Manager shall promptly, and in any event no later than thirty (30) days after the date of the Independent Directors’ notification to the Manager, select the Accounting Firm and instruct the Accounting Firm to recalculate the amounts or otherwise
          determine the information reflected or subsumed in the Payment Report which is disputed. The Accounting Firm shall resolve the dispute promptly, but in no event more than thirty (30) days after having the dispute submitted to it, unless the
          Accounting Firm provides notice to the Manager, the Company and the Independent Directors, in writing, that in its reasonable opinion resolution of the disputed issue or issues shall require additional time. The Accounting Firm will make a
          determination as to each of the items in dispute, which determination must be (i) in writing, (ii) furnished to each of the Manager, the Company and the Independent Directors and (iii) made in accordance with this Agreement, and which
          determination will be conclusive and binding on Manager and the Company, absent manifest error, and may be enforced in the courts specified in Section 6.8.  The fees and expenses of the Accounting Firm shall be borne by the Party (either the
          Company or the Manager) whose calculation of the applicable Disposition Payment is furthest from the amount determined by the Accounting Firm (and, for the avoidance of doubt, in no case shall such fees and expenses be included in the calculation
          of Company Transaction Costs).  Each of the Manager and the Company shall use reasonable efforts to cause the Accounting Firm to render its decision as soon as reasonably practicable, including by promptly complying with all reasonable requests
          by the Accounting Firm for information, books, records and similar items.  Within five (5) Business Days of the final determination of each of the items contained in the Payment Report that were in dispute, the Disposition Payment with respect to
          such Disposition shall be calculated and the Company and MIC Ohana shall pay to the Manager (from the escrowed amounts or otherwise) the amount of the Disposition Payment payable with respect to such Disposition.

              in cash, and the Manager hereby waives its rights under Section 7.2(e) of the Management Services Agreement (with respect to the Base Management Fee) and Section 7.3(d) of the Management Services Agreement (with respect to the Performance
              Fee) to invest all or a portion of such accrued and unpaid Base Management Fees and Performance Fees in shares of Company Common Stock and (b) any unreimbursed Costs at the time of such termination that are described in Section 9.1 of the
              Management Services Agreement shall be paid to the Manager in cash.

                     EXHIBIT A

          If at any time during the period between the date of this Agreement and the occurrence of a QTE, any change in the number of the
            Fully Diluted Shares shall occur as a result of any cancellation or forfeiture of the right to receive shares of Company Common Stock under the Company’s equity incentive plans or issuance of shares of Company Common Stock (other than in
            connection with any buy back, reclassification, recapitalization, stock split (including reverse stock split) or any stock dividend thereon with a record date during such period) (any such reduction or issuance, an “Adjusting Event”), including, without limitation, (a) in connection with the refinancing of the Company’s 2.00% Convertible Senior Notes due
            October 2023 or the refinancing of indebtedness of the Company, (b) in connection with the bona fide acquisition by the Company or any of its Subsidiaries of assets or an entity, (c) to the Manager pursuant to the Management Agreement or (d) to
            employees of the Company or its Subsidiaries in connection with the Company’s equity incentive plans, the values set forth under “Cumulative Proceeds,” “Cumulative Disposition Payment Amount” and “Cumulative Net Proceeds” in Table A-1 above
            shall be adjusted by multiplying such value by the ratio as determined by dividing the Fully Diluted Shares at the time of the calculation of the Disposition Payment by the Fully Diluted Shares as of the date hereof.  For example, Table A-2
            immediately below sets forth the adjusted values for “Cumulative Proceeds,” “Cumulative Disposition Payment Amount” and “Cumulative Net Proceeds” based on a 10% increase in the Fully Diluted Shares as a result of an Adjusting Event.  The
            Proceeds for each Disposition shall be equitably adjusted to account for changes in the number of Fully Diluted Shares after such Disposition for purposes of the Cumulative Proceeds calculations for subsequent Dispositions.  For example, if
            there is a Disposition with Proceeds of $1,000,000,000 and then a 10% increase in Fully Diluted Shares occurs due to a subsequent Adjusting Event, the Proceeds for such prior Disposition shall be deemed to be $1,100,000,000 when incorporated
            into the Cumulative Proceeds calculations for a subsequent Disposition.  This Proceeds adjustment shall be updated at each subsequent Disposition to reflect all Adjusting Events up to that point.

          Furthermore, if at any time during the period between the date of this Agreement and the occurrence of a QTE, any change in the
            number of the Fully Diluted Shares occurs as a result of an event other than an Adjusting Event (in any case, a “Non-Adjusting
              Event”), and thereafter there is an Adjusting Event, the Fully Diluted Shares at the time of the calculation will be adjusted as necessary to provide to the Parties the same economic effect as contemplated by this Agreement as if the
            Non-Adjusting Event had not occurred.  For example, if there is a 100% increase in Fully Diluted Shares subsequent to a Disposition (from 86,599,870 to 173,199,740) due to a Non-Adjusting Event, and then a further 10% increase in Fully Diluted
            Shares to 190,519,714 occurs due to a subsequent Adjusting Event, the Fully Diluted Shares for the purposes of these calculations will be assumed to be 95,259,857 (i.e. a 10% adjustment to the original 86,599,870 before the Non-Adjusting Event
            occurred).

          Hypothetical Example (in USD$)

          This example assumes that the fully diluted shares outstanding for each Disposition below is equal to Fully Diluted Shares.

          

          

          First, the Company receives Proceeds of $2,000 million from the sale of assets.

          
            	
                    ●

                  	
                    In that case, a Disposition Payment of $58.2 million ($2,000 million x 0.0291) would be payable.

                  


          

          Second, the Company receives Proceeds of $1,500 million from the sale of assets (for a total Cumulative Proceeds of $3,500 million).

          
            	
                    ●

                  	
                    The Cumulative Disposition Payment would increase to $112.7 million, which is interpolated based on the range of Cumulative Proceeds and Disposition Payment % of Cumulative Proceeds
                      provided, as follows:

                  


          

          
            	
                    o

                  	
                    $3,500 million less $3,488.6 million or $11.4 million, divided by

                  


          

          
            	
                    o

                  	
                    $3,588.1 million less $3,488.6 million or $99.5 million, multiplied by

                  


          

        

         

        

        
          A - 3 

          
            


        

        
          
            	
                    o

                  	
                    3.46% less 3.19% or 0.27%, plus

                  


          

          
            	
                    o

                  	
                    3.19%, multiplied by

                  


          

          
            	
                    o

                  	
                    $3,500

                  


          

          
            	
                    ●

                  	
                    The Disposition Payment payable for the second Disposition would be $54.5 million (the difference between $112.7 million and the $58.2 million already paid).

                  


          

          Third, the remainder of the Company is sold for Proceeds of $1,500 million (for a total Cumulative Proceeds of $5,000 million).

          
            	
                    ●

                  	
                    The Cumulative Disposition Payment would increase to $305.0 million (the product of $5,000 million and 0.061).

                  


          

          The Disposition Payment payable would be $192.3 million (the difference between $305.0 million and the $112.7 million already paid).
