DETERMINATION OF REALIZED TAX BENEFIT

Section 2.1 754 Election(a) . The Corporate Taxpayer shall cause OpCo and each of its applicable direct or indirect Subsidiaries that is treated as a partnership for U.S. federal income Tax purposes to have in effect an election under Section 754 of the Code (or any similar provisions of applicable state, local or non-U.S. tax law) for each Taxable Year. The Corporate Taxpayer shall use commercially reasonable efforts to cause each Person in which OpCo owns a direct or indirect equity interest (other than a Subsidiary) that is so treated as a partnership for U.S. federal income Tax purposes to have in effect such an election for each Taxable Year.

Section 2.2 Basis Schedule. Within ninety (90) calendar days after the due date (including extensions) of IRS Form 1120 (or any successor form) of the Corporate Taxpayer for each relevant Taxable Year, the Corporate Taxpayer shall deliver to the Rights Holder Representative, a schedule (a “Basis Schedule”) that shows, in reasonable detail necessary to perform the calculations required by this Agreement, (a) the Unit Transferred Basis of each Reference Asset, if any, (b) the Blocker Attributes, if any, (c) the Blocker Transferred Basis of each Reference Asset, if any, (d) the IPO Basis of each Reference Asset, if any, (e) the Exchange Transferred Basis of each Reference Asset, if any, (f) the Basis Adjustment with respect to the Reference Assets in respect of each Rights Holder as a result of the Exchanges effected in such Taxable Year or any prior Taxable Year by such Rights Holder, if any, (g) the Non-Stepped Up Tax Basis of the Reference Assets in respect of such Rights Holder as of each applicable Exchange Date, if any, (h) the period (or periods) over which the Reference Assets in respect of such Rights Holder are amortizable and/or depreciable and (i) the period (or periods) over which the Unit Transferred Basis, the Blocker Attributes, the Blocker Transferred Basis, the IPO Basis, the Exchange Transferred Basis and each Basis Adjustment is amortizable and/or depreciable. A Basis Schedule will become final and binding on the parties pursuant to the procedures set forth in Section 2.4(a) and may be amended by the parties pursuant to the procedures set forth in Section 2.4(b) (subject to the procedures set forth in Section 2.4(b)). All costs and expenses incurred in connection with the provision and preparation of the Blocker Attribute Schedule, the Basis Schedules and the Tax Benefit Schedules for each Rights Holder in compliance with this Agreement shall be borne by the Corporate Taxpayer.

Section 2.3 Tax Benefit Schedule.

(a) Tax Benefit Schedule. Within ninety (90) calendar days after the due date (including extensions) of IRS Form 1120 (or any successor form) of the Corporate Taxpayer for any Taxable Year, the Corporate Taxpayer shall provide to the Rights Holder Representative a schedule showing, in reasonable detail, the calculation of the Realized Tax Benefit and Tax Benefit Payment or the Realized Tax Detriment (and lack of a Tax Benefit Payment), as applicable, Attributable to each Rights Holder for such Taxable Year (a “Tax Benefit Schedule”). Each Tax Benefit Schedule will become final as provided in Section 2.4(a) and may be amended as provided in Section 2.4(b) (subject to the procedures set forth in Section 2.4(b)).

(b) Applicable Principles.

(i) General. The Realized Tax Benefit (or the Realized Tax Detriment) for each Taxable Year is intended to measure the decrease (or increase) in the actual liability for Taxes payable or economically borne by the Corporate Taxpayer for such Taxable Year attributable to the Tax Attributes, determined using a “with and without” methodology. Carryovers or carrybacks of any Tax item attributable to any of the Tax Attributes shall be considered to be subject to the rules of the Code and the Treasury Regulations or the appropriate provisions of U.S. Tax law, as applicable, governing the use, limitation and expiration of carryovers or carrybacks of the relevant type, except as otherwise provided by this Agreement. If a carryover or carryback of any Tax item includes a portion that is attributable to any Tax Attribute and another portion that is not, such portions shall be considered to be used in accordance with the “with and without” methodology. The Actual Tax Liability shall be calculated taking into account the Intended Tax Treatment.

- 13 -

(ii) Applicable Principles of Section 734(b) Exchanges. Notwithstanding any provisions to the contrary in this Agreement the Intended Tax Treatment shall not be required to apply to payments hereunder to an Exchanging Holder in respect of a Section 734(b) Exchange by such Exchanging Holder. For the avoidance of doubt, payments made under this Agreement relating to a Section 734(b) Exchange shall not be treated as resulting in a Basis Adjustment to the extent such payments are treated as Imputed Interest. The parties intend that (A) an Exchanging Holder that has made a Section 734(b) Exchange shall, with respect to the Basis Adjustment resulting from such Section 734(b) Exchange or any payments hereunder in respect of such Section 734(b) Exchange, be entitled to Tax Benefit Payments attributable to such Basis Adjustments only to the extent such Basis Adjustments are allocable to the Corporate Taxpayer following such Section 734(b) Exchange (without taking into account any concurrent or subsequent Exchanges) and (B) if, as a result of a subsequent Exchange, an increased portion of the Basis Adjustments resulting from such Section 734(b) Exchange or any payments hereunder in respect of such Section 734(b) Exchange becomes allocable to the Corporate Taxpayer, then the Exchanging Holder that makes such subsequent Exchange shall be entitled to a Tax Benefit Payment calculated in respect of such increased portion.

Section 2.4 Procedures, Amendments.

(a) Procedure. Each time the Corporate Taxpayer delivers to the Rights Holder Representative an applicable Schedule under this Agreement, including any Amended Schedule delivered pursuant to Section 2.4(b), any Early Termination Schedule or any amended Early Termination Schedule, the Corporate Taxpayer shall also (i) deliver to the Rights Holder Representative supporting schedules and work papers, as determined by the Corporate Taxpayer or as reasonably requested by the Rights Holder Representative, that provide a reasonable level of detail regarding the data and calculations that were relevant for purposes of preparing the Schedule and (ii) allow the Rights Holder Representative reasonable access at no cost to the appropriate representatives at the Corporate Taxpayer in connection with a review of such Schedule. Without limiting the generality of the preceding sentence, the Corporate Taxpayer shall ensure that any Tax Benefit Schedule or Early Termination Schedule that is delivered to the Rights Holder Representative, along with any supporting schedules, valuation reports and work papers, provides a reasonably detailed presentation of the calculation of the Actual Tax Liability (the “with” calculation) and the Hypothetical Tax Liability (the “without” calculation) and identifies any assumptions or operating procedures or principles that were used for purposes of such calculations. An applicable Schedule or amendment thereto shall become final and binding on all parties unless the Rights Holder Representative, within thirty (30) calendar days after receiving any Schedule or amendment thereto, provides the Corporate Taxpayer with a notice of an objection to such Schedule or amendment thereto (“Objection Notice”) or such earlier date as the Rights Holder Representative provides written notice to the Corporate Taxpayer that it has no objections to the Schedule. If the Corporate Taxpayer and Rights Holder Representative, for any reason, are unable to successfully resolve the issues raised in any Objection Notice within thirty (30) calendar days after the Rights Holder Representative gives the Corporate Taxpayer such Objection Notice, the Corporate Taxpayer and the Rights Holder Representative shall employ the reconciliation procedures described in Section 7.10 (the “Reconciliation Procedures”), in which case such Schedule or Amended Schedule shall become binding in accordance with Section 7.10.

(b) Amended Schedule. The applicable Schedule for any Taxable Year may be amended from time to time by the Corporate Taxpayer (i) in connection with a Determination affecting such Schedule, (ii) to correct material inaccuracies in the Schedule, including those identified as a result of the receipt of additional factual information relating to a Taxable Year after the date the Schedule was provided to the Rights Holder Representative, (iii) to comply with an Expert’s determination under the Reconciliation Procedures, (iv) to reflect a material change in the Realized Tax Benefit or the Realized Tax Detriment for such Taxable Year attributable to a carryback or carryforward of a loss or other tax item to such Taxable Year or (v) to reflect a material change in the Realized Tax

- 14 -

Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year (any such Schedule, an “Amended Schedule”); provided, however, that an amendment under clause (i) attributable to an audit of a Tax Return by the Corporate Taxpayer, OpCo or Subsidiary thereof shall not be made on an Amended Schedule unless and until there has been a Determination with respect to such change. The Corporate Taxpayer shall provide an Amended Schedule to the Rights Holder Representative within thirty (30) calendar days of the occurrence of an event referred to in clauses (i) through (v) of the preceding sentence, and any such Amended Schedule shall be subject to the approval procedures described in Section 2.4(a).

ARTICLE III

TAX BENEFIT PAYMENTS

Section 3.1 Payments; Timing of Payments. Within five (5) Business Days of a Tax Benefit Schedule becoming final in accordance with Section 2.4(a) and Section 7.10, if applicable, the Corporate Taxpayer shall pay to each Rights Holder for such Taxable Year the Tax Benefit Payment determined pursuant to Section 3.1(a) that is Attributable to such Rights Holder. Each such Tax Benefit Payment shall be made by wire transfer of immediately available funds to the bank account previously designated by the applicable Rights Holder to the Corporate Taxpayer, or as otherwise agreed by the Corporate Taxpayer and such Rights Holder. For the avoidance of doubt, (a) no Tax Benefit Payment shall be made in respect of estimated tax payments and (b) the payments provided for pursuant to the above sentence shall be computed separately for each Rights Holder. No Rights Holder shall be required under any circumstances to make a payment or return a payment to the Corporate Taxpayer in respect of any portion of any Tax Benefit Payment previously paid by the Corporate Taxpayer to such Rights Holder (including any portion of any Early Termination Payment).

(a) For purposes of this Agreement:

(i) A “Tax Benefit Payment” in respect of a Rights Holder for a Taxable Year means an amount, not less than zero, equal to the sum of (A) the Net Tax Benefit that is Attributable to such Rights Holder and (B) the Accrued Amount with respect thereto. For the avoidance of doubt, for Tax purposes, the Accrued Amount shall not be treated as interest, but instead, shall be treated as additional consideration in the applicable transaction, unless otherwise required by law.

(ii) Subject to Section 3.4, the “Net Tax Benefit” for a Taxable Year shall be an amount equal to the excess, if any, of 85% of the Cumulative Net Realized Tax Benefit as of the end of such Taxable Year, over the total amount of payments previously made under the first sentence of Section 3.1(a) (excluding payments attributable to Accrued Amounts); provided, that if there is no such excess (or if a deficit exists), no Rights Holder shall be required to make a payment (or return a payment) to the Corporate Taxpayer in respect of any portion of any Tax Benefit Payment previously made by the Corporate Taxpayer to such Rights Holder.

(iii) The “Accrued Amount” with respect to any Net Tax Benefit shall equal an amount determined in the same manner as interest on the Net Tax Benefit calculated at the Agreed Rate from the due date (without extensions) for filing IRS Form 1120 (or any successor form) of the Corporate Taxpayer with respect to Taxes for such Taxable Year until the payment date under Section 3.1(a).

(b) PubCo, OpCo and the Rights Holders hereby acknowledge and agree that, as of the date of the Agreement and as of the date of any future Exchange that may be subject to this Agreement, the aggregate value of the Tax Benefit Payments cannot be reasonably ascertained for U.S. federal income and other applicable tax purposes. Notwithstanding anything herein to the contrary, unless otherwise specified by a Rights Holder in a written notice to PubCo, the aggregate Tax Benefit Payments herein (other than amounts accounted for as interest under the Code) with respect to any Exchange by a Rights Holder, shall not exceed 100% of the fair market value

- 15 -

of the consideration received (whether as a cash payment, as Class A shares or as other consideration, but excluding, for the avoidance of doubt, the fair market value of the Tax Benefit Payments hereunder) in such Exchange or other applicable transaction (the “Exchange Consideration”) such that the stated maximum selling price (within the meaning of Treasury Regulation 15A.453-1(c)(2) is equal to 200% of the Exchange Consideration.

Section 3.2 No Duplicative Payments. It is intended that the provisions of this Agreement will not result in duplicative payment of any amount (including interest) required under this Agreement. It is also intended that the provisions of this Agreement will result in 85% of the Cumulative Net Realized Tax Benefits of the Corporate Taxpayer, and the Accrued Amounts thereon, being paid to the Rights Holders pursuant to this Agreement. The provisions of this Agreement shall be construed in the appropriate manner so that these fundamental results are achieved.

Section 3.3 Payments in United States Dollars. All payments to be made under this Agreement shall be made in United States dollars.

Section 3.4 Pro Rata Payments. Notwithstanding anything in Section 3.1 to the contrary, to the extent that the aggregate potential Realized Tax Benefit of the Corporate Taxpayer with respect to the Tax Attributes is limited in a particular Taxable Year because the Corporate Taxpayer does not have sufficient taxable income, the Net Tax Benefit for that Taxable Year shall be allocated among all parties then-eligible to receive Tax Benefit Payments under this Agreement in proportion to the amounts of Net Tax Benefit for that Taxable Year, respectively, that would have been Attributable to each Rights Holder if the Corporate Taxpayer had sufficient taxable income so that there were no such limitation.

Section 3.5 Payment Ordering. If for any reason the Corporate Taxpayer does not fully satisfy its payment obligations to make all Tax Benefit Payments due under this Agreement in respect of a particular Taxable Year, then the Corporate Taxpayer and the Rights Holders agree that (a) Tax Benefit Payments for such Taxable Year shall be allocated to all parties eligible to receive Tax Benefit Payments under this Agreement in such Taxable Year in proportion to the amounts of Tax Benefit Payments, respectively, that would have been made to each Rights Holder if the Corporate Taxpayer had sufficient cash available to make such Tax Benefit Payments and (b) no Tax Benefit Payments shall be made in respect of any Taxable Year until all Tax Benefit Payments to all Rights Holders in respect of all prior Taxable Years have been made in full.

Section 3.6 IPO Basis Exchange. Notwithstanding anything to the contrary herein, any and all Tax Benefit Payments that would otherwise be made pursuant to this Agreement to the Exchanging Holder with respect to any IPO Basis shall be held in cash by the Corporate Taxpayer for the benefit of the Exchanging Holder (without any interest thereon) (such withheld amount, the “Accrued Payment”). Promptly following the time the Exchanging Holder has exchanged Units, such Accrued Payment Attributable to Exchanging Holder with respect to the exchanged Units shall be paid by the Corporate Taxpayer to the Exchanging Holder.

Section 3.7 Intended Tax Treatment.

(a) The parties hereto agree that it is their intention, for U.S. federal (and applicable state and local) income tax purposes, that:

(i) A Tax Benefit Payment paid to a Rights Holder that is an Exchanging Holder in respect of a Unit that is subject to the Exchange Agreement shall be treated as in part additional purchase price for such Unit and in part Imputed Interest;

(ii) A Tax Benefit Payment (other than Imputed Interest thereon) paid to a Rights Holder that is a Unit Transferred Basis Rights Holder is in respect of a Unit that was subject to the Unit Contribution shall be treated as nonqualifying property or money received pursuant to Section 351 and/or Section 356 of the Code;

- 16 -

(iii) A Tax Benefit Payment (other than Imputed Interest thereon) paid to the Blocker Shareholder in respect of a Unit that was acquired by PubCo pursuant to the Blocker Merger shall be treated as nonqualifying property or money for purposes of Section 351 and/or Section 356 of the Code received in the Blocker Merger;

(iv) each Exchange shall give rise to Basis Adjustments;

(v) all Tax Benefit Payments (other than Imputed Interest thereon) attributable to the Exchange Transferred Basis, Basis Adjustments or IPO Basis (with respect to an IPO Basis Payment received as a result of an Exchange) shall be treated as subsequent upward purchase price adjustments with respect to the Units exchanged in the applicable Exchange that have the effect of creating additional Basis Adjustments to Reference Assets in the year of payment;

(vi) all Tax Benefit Payments (other than Imputed Interest thereon) attributable to the Unit Transferred Basis, the Blocker Transferred Basis or Blocker Attributes, or IPO Basis (with respect to an IPO Basis Payment received in respect of the Unit Contribution or the Blocker Merger) shall be treated as having the effect of creating additional Basis Adjustments to the Reference Assets in the year of payment; and

(vii) the portion of the Tax Benefit Payment that must be accounted for as Imputed Interest shall be deductible by the Corporate Taxpayer (collectively, the “Intended Tax Treatment”).

ARTICLE IV

TERMINATION

Section 4.1 Termination of Agreement; Elective Early Termination; Automatic Early Termination.

(a) In General. This Agreement shall terminate at the time that all Tax Benefit Payments have been made to the Rights Holders under this Agreement.

(b) Elective Early Termination. Notwithstanding Section 4.1(a), with the written approval of a majority of the Independent Directors, the Corporate Taxpayer may terminate this Agreement by paying to the Rights Holders the Early Termination Payment together with the other amounts required by this paragraph. If the Corporate Taxpayer chooses to exercise its right of early termination pursuant to this Section 4.1(b), the Corporate Taxpayer shall deliver to the Rights Holder Representative irrevocable written notice of such decision to exercise such right (“Early Termination Notice”) and a schedule (the “Early Termination Schedule”) showing in reasonable detail the calculation of the Early Termination Payment. The Early Termination Schedule shall become final and binding on all parties in accordance with the procedures set forth Section 2.4(a). Upon finalization of the Early Termination Schedule, the Corporate Taxpayer shall pay to each Rights Holders at the time set forth in Section 4.2, such Rights Holder’s Attributable portion of (1) the Early Termination Payment, (2) the Tax Benefit Payment due and payable but unpaid as of the date of the Early Termination Notice and (3) the Tax Benefit Payment due for a Taxable Year ending prior to, with or including the date of the Early Termination Notice (except to the extent that such amount is included in the Early Termination Payment).

(c) Acceleration Upon Material Breach of this Agreement. Subject to Section 5.2, in the event that the Corporate Taxpayer breaches any of its material obligations under this Agreement, whether as a result of a failure to make a payment when due, failure to honor any other material obligations required hereunder or by operation of law as a result of the rejection of this Agreement in a case commenced under bankruptcy laws or otherwise, then all obligations hereunder shall be accelerated, the Corporate Taxpayer shall be deemed to have

- 17 -

delivered an Early Termination Notice on the first date of such breach and the Corporate Taxpayer shall pay to the Rights Holders at the time specified in Section 4.2, such Rights Holder’s Attributable portion of (1) the Early Termination Payment, (2) any Tax Benefit Payment that is due and payable but unpaid as of such date and (3) any Tax Benefit Payment due for the Taxable Year ending prior to, with or including such date (except to the extent that such amount is included in the Early Termination Payment). The parties agree that the failure to make any payment due pursuant to this Agreement within three (3) months of the date such payment is due shall be deemed to be a breach of a material obligation under this Agreement for all purposes of this Agreement.

(d) Acceleration Upon Change of Control. In the event of a Change of Control, all obligations hereunder to be accelerated. In such event, the Corporate Taxpayer shall be deemed to have delivered an Early Termination Notice on the date of such Change of Control and the Corporate Taxpayer shall pay to the Rights Holders at the time specified in Section 4.2 (1) the Early Termination Payment, (2) any Tax Benefit Payment that is due and payable but unpaid as such date and (3) any Tax Benefit Payment due for the Taxable Year ending prior to, with or including such date (except to the extent that such amount is included in the Early Termination Payment). The Corporate Taxpayer shall use its reasonable best efforts to provide to the Rights Holder Representative an Early Termination Schedule showing in reasonable detail the calculation of the Early Termination Payment with respect to an expected Change of Control as far in advance as is reasonably practicable of such Change of Control (but no more than thirty (30) Business Days in advance) so as to enable the calculation of the Early Termination Payment to be finalized pursuant to Section 2.4(a) prior to the date of the effective date of the Change of Control. Notwithstanding the foregoing, where the parties anticipate a Change of Control but are not certain of the date on which such Change of Control will occur, the Corporate Taxpayer and the Rights Holder Representative may agree to base the calculations contemplated by this Section 4.1(d) on a date other than the closing date of the Change of Control.

(e) For the avoidance of doubt, this Section 4.1 shall not prevent the Corporate Taxpayer and the Rights Holder Representative from negotiating a termination of the Rights Holders’ rights under this Agreement in exchange for a payment that is different than the Early Termination Payment and which is binding on all Rights Holders.

Section 4.2 Payment upon Early Termination Event.

(a) Any amount required to be paid pursuant to Section 4.1(b) or Section 4.1(c) shall be paid within five (5) Business Days after the corresponding Early Termination Schedule is finalized pursuant to Section 2.4. Any amount required to be paid pursuant to Section 4.1(d) shall be paid on the date of the closing of the Change of Control. All such payments shall be made by wire transfer of immediately available funds to a bank account designated by the Rights Holders, or as otherwise agreed by the Corporate Taxpayer and the Rights Holder Representative.

(b) The “Early Termination Payment” with respect to an Early Termination Event shall equal the present value as of the corresponding Early Termination Date, discounted at the Early Termination Rate as of such date, of all Tax Benefit Payments that would be required to be paid by the Corporate Taxpayer to the Rights Holders beginning from the Early Termination Date, calculated by applying the Valuation Assumptions.

ARTICLE V

PAYMENT MECHANICS AND COMPLIANCE WITH INDEBTEDNESS

Section 5.1 Late Payments. The amount of all or any portion of any Tax Benefit Payment or Early Termination Payment (or other payment pursuant to Section 4.1 or Section 4.2) not made by the Corporate Taxpayer to the Rights Holders when due under the terms of this Agreement (other than pursuant to Section 5.2) shall accrue interest at the Default Rate commencing from the date on which such payment was due and payable.

- 18 -

Section 5.2 Compliance with Indebtedness. Notwithstanding anything to the contrary herein, if, at the time any amounts become due and payable hereunder, the Corporate Taxpayer is not permitted, pursuant to the terms of the Corporate Taxpayer’s debt financing arrangements, to pay such amounts, or the Corporate Taxpayer’s Subsidiaries are not permitted, pursuant to the terms of the Corporate Taxpayer’s (or the applicable Subsidiary’s) debt financing arrangements, to make dividends, loans or other transfers to the Corporate Taxpayer to allow the Corporate Taxpayer to pay such amounts, then the Corporate Taxpayer shall by notice to the Rights Holder Representative be permitted to defer the payment of such amounts to the minimum extent necessary until each condition rendering the payment of such amounts impermissible as described in this Section 5.2 is no longer applicable. At the time such condition is no longer applicable and no other such condition exists, such amounts (together with accrued and unpaid interest thereon as described in this Section 5.2) shall become due and payable immediately. If the Corporate Taxpayer defers the payment of any such amounts pursuant to the first sentence in this Section 5.2, such amounts shall accrue interest at the Agreed Rate from the date that such amounts originally became due and owing pursuant to the terms hereof to the date that such amounts are paid. For the avoidance of doubt, any payment not made due to the preceding sentence shall not be deemed a breach under Section 4.1(c) of this Agreement unless and until such payment remains unpaid thirty (30) calendar days after the date on which such condition described in this Section 5.2 is no longer applicable. The Corporate Taxpayer agrees to use commercially reasonable efforts to cure any condition rendering the payment of such amounts impermissible as described in this Section 5.2 and to cause the Corporate Taxpayer and its Subsidiaries to pay dividends or make loans (including, to the extent commercially reasonable, granting access to any revolving credit facility or other source of liquidity to facilitate the payment of such dividends or loans), to the extent consistent with the terms of their outstanding indebtedness and any applicable law, to the extent necessary to make payments hereunder.

Section 5.3 Conflicting Agreements. Unless the Rights Holder Representative otherwise agrees in writing, the Corporate Taxpayer shall use commercially reasonable efforts not to, and shall cause the Corporate Taxpayer’s Subsidiaries to use commercially reasonable efforts not to, enter into any agreement or indenture or any amendment or other modification to any agreement or indenture (including, in each case, in connection with any refinancing) or incur, create or assume any obligations in respect of indebtedness for borrowed money (excluding any trade payables, intercompany debt or similar obligations) (“Senior Obligations”), in each case, after the date hereof, that would reasonably be expected to, directly or indirectly, impede (or further impede) its ability to make payments under this Agreement (other than any Early Termination Payment) in accordance with its terms, including any agreement that would, directly or indirectly, impede (or further impede) the ability of the Corporate Taxpayer to pay amounts payable under this Agreement (other than any Early Termination Payment) or the ability of the Corporate Taxpayer’s Subsidiaries to upstream cash (by dividend, loan or other transfer) to the Corporate Taxpayer to fund amounts payable by the Corporate Taxpayer under this Agreement (other than any Early Termination Payment); provided that, for the avoidance of doubt, any interest incurred, accrued or otherwise payable in accordance with a Senior Obligation shall not be deemed to, directly or indirectly, impede (or further impede) the Corporate Taxpayer’s ability to make payments under this Agreement or the ability of the Corporate Taxpayer’s Subsidiaries to upstream cash to the Corporate Taxpayer. Notwithstanding any other provision of this Agreement to the contrary, to the extent that the Corporate Taxpayer enters into future Tax receivable or other similar agreements (“Future TRAs”), the Corporate Taxpayer shall ensure that the terms of any such Future TRA shall provide that the Tax Attributes subject to this TRA Agreement shall be senior in priority in all respects to any Tax attributes subject to any such Future TRA for purposes of calculating the amount and timing of payments under any such Future TRA and that there is no duplication of Tax Attributes (and payments with respect thereto) that are subject to this Agreement and Tax attributes (and payment obligations with respect thereto) that are subject to any Future TRAs. For the avoidance of doubt, any payment required to be made by the Corporate Taxpayer to the Rights Holders under this Agreement shall be pari passu in right of payment with all current or future unsecured obligations of the Corporate Taxpayer and its Subsidiaries that are not Senior Obligations.

ARTICLE VI

NO DISPUTES; CONSISTENCY; COOPERATION

Section 6.1 Participation in the Corporate Taxpayer’s and OpCo’s Tax Matters.

(a) Except as otherwise provided in this Agreement, the Corporate Taxpayer and OpCo shall have full responsibility for, and sole discretion over, all tax matters concerning the Corporate Taxpayer and OpCo, respectively, including the preparation, filing or amending of any Tax Return and defending, contesting or settling any issue pertaining to taxes, subject to a requirement that the Corporate Taxpayer and OpCo, as applicable act in good faith in connection with their direct or indirect control of any matter which is reasonably expected to affect the Rights Holders’ rights and obligations under this Agreement.

(b) Notwithstanding the foregoing, the Corporate Taxpayer or OpCo, as applicable, shall notify the Rights Holder Representative in writing of the commencement of, and keep the Rights Holder Representative reasonably informed with respect to, any tax audit or tax administrative or judicial proceeding of the Corporate Taxpayer (or its Subsidiaries) or OpCo by a Taxing Authority the outcome of which could reasonably be expected to adversely affect the timing of, or the amount of, any Tax Benefit Payment (any “Tax Claim”), and shall give the Rights Holder Representative reasonable opportunity to provide information and participate in the applicable portion of such Tax Claim, including attending any meetings with any Taxing Authority, employing counsel separate from the counsel employed by the Corporate Taxpayer or OpCo, as applicable, and having the opportunity to reasonably comment on and approve all material submissions made by the Corporate Taxpayer or OpCo, as applicable, to any Taxing Authority. Notwithstanding anything herein to the contrary, without the consent of the Rights Holder Representative, which consent shall not be unreasonably withheld, conditioned or delayed, the Corporate Taxpayer or OpCo, as applicable, shall not, and shall cause each respective Subsidiary not to, (i) change any accounting method, or amend or take any position inconsistent with a previously-filed Tax Return of any such entity, in each case, if such action could materially and adversely affect the Tax Benefit Payments or (ii) settle or otherwise resolve any Tax Claim, if such settlement could have a materially adverse effect on a Rights Holder’s rights (including the right to receive payments) under this Agreement.

Section 6.2 Cooperation. Each of the Corporate Taxpayer, OpCo and the Rights Holder Representative shall (a) furnish to the other party in a timely manner such information, documents and other materials as the other party may reasonably request for purposes of making or approving any determination or computation necessary or appropriate under this Agreement, preparing any Tax Return or contesting, participating in, or defending any audit, examination or controversy with any Taxing Authority including pursuant to Section 6.1, (b) make itself available to the other party and its representatives to provide explanations of documents and materials and such other information as the requesting party or its representatives may reasonably request in connection with any of the matters described in clause (a) above, and (c) reasonably cooperate in connection with any such matter,. Upon the request of any Rights Holder the Corporate Taxpayer shall cooperate in taking any action reasonably requested by such Rights Holder in connection with (i) its Tax or financial reporting or (ii) the consummation of any assignment or transfer of any of its rights and/or obligations under this Agreement, including without limitation, providing any information (including projections of taxable income and Tax Benefit Payments) or executing any documentation. In addition, the Corporate Taxpayer shall not, and shall cause each of its Subsidiaries not to, take any action or omit to take any action, in each case, that has the primary purpose of circumventing the attainment of or otherwise reducing any Tax Benefit Payment or Early Termination Payment under this Agreement or triggering an Early Termination Event under this Agreement.

Section 6.3 Consistency. The Corporate Taxpayer and the Rights Holders agree to report and cause to be reported for all purposes, including U.S. federal, state and local Tax purposes and financial reporting purposes, all Tax-related items (including, without limitation, the Basis Adjustments and each Tax Benefit Payment) in a manner consistent with that contemplated by this Agreement or specified by the Corporate Taxpayer in any Schedule required to be provided by or on behalf of the Corporate Taxpayer under this Agreement unless otherwise required by law. The Corporate Taxpayer shall (and shall cause OpCo and its other Subsidiaries to) use commercially reasonable efforts (for the avoidance of doubt, taking into account the interests and entitlements of all Rights Holders under this Agreement) to defend the Tax treatment contemplated by this Agreement, including the Intended Tax Treatment, and any Schedule in any audit, contest or similar proceeding with any Taxing Authority.

Section 7.9 Resolution of Disputes.

(a) Other than with respect to any disputes under Section 2.4, Section 4.1, or Section 4.2 (which are to be resolved pursuant to Section 7.10) or claims for specific performance or other equitable relief, any and all disputes hereunder which cannot be settled amicably between or among the Corporate Taxpayer, any Rights Holder and/or the Rights Holder Representative, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be finally settled by arbitration conducted by a single arbitrator in accordance with the then existing Rules of Arbitration of the International Chamber of Commerce. The place of arbitration shall be New York, New York. The parties to such arbitration shall jointly select a single arbitrator who shall have the authority to hold hearings and to render a decision in accordance with the then existing Rules of Arbitration of the International Chamber of Commerce. If the parties to such arbitration fail to agree on the selection of an arbitrator within thirty (30) calendar days of the receipt of the request for arbitration, the arbitrator shall be selected by the International Chamber of Commerce. The arbitrator shall be a lawyer. The arbitration shall be governed by the Federal Arbitration Act, 9 U.S.C. Section 1, et seq., and judgment on the award may be entered by any court having jurisdiction thereof. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

- 23 -

(b) Notwithstanding the provisions of Section 7.9(a), either the Corporate Taxpayer or the Rights Holders or Rights Holder Representative may bring an action or special proceeding in any court of competent jurisdiction for the purpose of compelling a party to arbitrate in accordance with Section 7.9(a), seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing an arbitration award and, for the purposes of this Section 7.9(b), the Rights Holders or Rights Holder Representative (i) expressly consents to the application of Section 7.9(c) to any such action or proceeding, and (ii) irrevocably appoints the Corporate Taxpayer as its agent for service of process in connection with any such action or proceeding and agrees that service of process upon such agent, who shall promptly advise the Rights Holders or Rights Holder Representative of any such service of process, shall be deemed in every respect effective service of process upon the Rights Holders or Rights Holder Representative in any such action or proceeding.

(c) THE CORPORATE TAXPAYER AND THE RIGHTS HOLDERS AND RIGHTS HOLDER REPRESENTATIVE EACH HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF COURTS LOCATED IN THE STATE OF DELAWARE AND AGREES THAT ANY JUDICIAL PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF SECTION 7.9(B) OR SECTION 7.17 SHALL BE BROUGHT AND DETERMINED EXCLUSIVELY IN ANY STATE COURT LOCATED IN THE STATE OF DELAWARE AND ANY STATE APPELLATE COURT THEREFROM WITHIN THE STATE OF DELAWARE (OR, IF SUCH STATE COURTS REFUSE TO ACCEPT JURISDICTION OVER A PARTICULAR MATTER, ANY FEDERAL COURT WITHIN THE STATE OF DELAWARE).

(d) The parties acknowledge that the forum designated by Section 7.9(c) has a reasonable relation to this Agreement and to the parties’ relationship with one another.

Section 7.10 Reconciliation. In the event that the Corporate Taxpayer and the Rights Holder Representative are unable to resolve a disagreement with respect to the matters governed by Section 2.4, Section 4.1, and Section 4.2 within the relevant period designated in this Agreement (including the finalization of any Schedule or the amount of any Tax Benefit Payment or Early Termination Payment (or other payment pursuant to the Section 4.1) required to be made by the Corporate Taxpayer to the Rights Holders under this Agreement) (a “Reconciliation Dispute”), the Reconciliation Dispute shall be submitted for determination to a nationally recognized expert in the particular area of disagreement (the “Expert”) mutually acceptable to both parties. The Expert shall be a nationally recognized accounting, consulting or valuation firm (other than a so-called “Big Four” accounting firm) mutually selected by the Corporate Taxpayer and the Rights Holder Representative. The Corporate Taxpayer and the Rights Holder Representative shall instruct the Expert to, and the Expert shall, make a final determination of such Reconciliation Dispute in accordance with the guidelines and procedures set forth in this Agreement. The Corporate Taxpayer and the Rights Holder Representative will reasonably cooperate with the Expert during the term of its engagement. The Corporate Taxpayer and the Rights Holder Representative shall instruct the Expert not to, and the Expert shall not, assign a value to any item in dispute greater than the greatest value for such item assigned by the Corporate Taxpayer, on the one hand, or the Rights Holder Representative, on the other hand, or less than the smallest value for such item assigned by the Corporate Taxpayer, on the one hand, or the Rights Holder Representative, on the other hand. The Corporate Taxpayer and the Rights Holder Representative shall also instruct the Expert to, and the Expert shall, make its determination based solely on presentations by the Corporate Taxpayer and the Rights Holder Representative that are in accordance with the guidelines and procedures set forth in this Agreement and not on the basis of an independent review. If the Reconciliation Dispute is not resolved before any payment that is the subject of the Reconciliation Dispute is due or any Tax Return reflecting the subject of the Reconciliation Dispute is due, such payment shall be made on the date prescribed by this Agreement and such Tax Return may be filed as prepared by the Corporate Taxpayer, subject to adjustment or amendment upon resolution. The costs and expenses relating to the engagement of such Expert or the amendment of any Tax Return shall be borne by the Corporate Taxpayer, except that the Rights Holder Representative shall pay a portion of the fees and expenses of the Expert equal to the percentage by which the portion of the disputed amounts not awarded to Rights Holders (if any) bears to the aggregate amount actually disputed. Any dispute as to whether a dispute is a Reconciliation Dispute, within the meaning of this Section 7.10 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this Section 7.10 shall be binding on the Corporate Taxpayer and the Rights Holder Representative and may be entered and enforced in any court having jurisdiction.

- 24 -

Section 7.11 Withholding. The Corporate Taxpayer shall be entitled to deduct and withhold from any payment payable pursuant to this Agreement such amounts as the Corporate Taxpayer is required to deduct and withhold with respect to the entering into this Agreement or the making of such payment under the Code, or any applicable provision of state, local or non-U.S. tax law, provided further, that the Corporate Taxpayer (i) gives ten (10) days advance written notice of its intention to make such withholding to the Rights Holder Representative, (ii) identifies the legal basis requiring such withholding and (iii) gives the Rights Holder Representative a reasonable opportunity to establish that such withholding is not legally required or may be reduced. To the extent that amounts are so withheld and paid over to the appropriate Taxing Authority by the Corporate Taxpayer, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the applicable Rights Holder. The Corporate Taxpayer shall provide evidence of such payments to the Rights Holders to the extent that such evidence is available. Each Rights Holder shall deliver to the Corporate Taxpayer at (i) the time such Rights Holder becomes a Rights Holder and (ii) the reasonable request of the Corporate Taxpayer, such properly completed and executed documentation reasonably requested by the Corporate Taxpayer as will permit such payments to be made without withholding or at a reduced rate of withholding (including IRS Form W-9 or the appropriate IRS Form W-8, as applicable).

Section 7.12 Admission of the Corporate Taxpayer into a Consolidated Group; Transfers of Corporate Assets.

(a) If the Corporate Taxpayer or any of its Subsidiaries is or becomes a member of an affiliated, consolidated, combined or unitary group of corporations that files a consolidated, combined or unitary income Tax Return pursuant to Sections 1501 et seq. of the Code or any corresponding provisions of state, local or foreign Tax law, then: (i) the provisions of this TRA Agreement shall be applied with respect to the group as a whole; and (ii) Tax Benefit Payments, Early Termination Payments and other applicable items hereunder shall be computed with reference to the consolidated, combined or unitary taxable income of the group as a whole.

(b) If any Person the income of which is included in the income of the Corporate Taxpayer or its Subsidiaries or the Corporate Taxpayer’s or its Subsidiaries’ affiliated or consolidated group transfers one or more Reference Assets to a corporation (or a Person classified as a corporation for U.S. federal income tax purposes) with which such entity does not file a consolidated Tax Return pursuant to Section 1501 of the Code or any corresponding provisions of state, local or non-U.S. Tax law, such entity, for purposes of calculating the amount of any Tax Benefit Payment or Early Termination Payment due hereunder, shall be treated as having disposed of such Reference Asset in a fully taxable transaction on the date of such contribution. The consideration deemed to be received in a transaction contemplated in the prior sentence shall be equal to the fair market value of the deemed transferred Reference Asset, plus (i) the amount of debt to which such Reference Asset is subject, in the case of a transfer of an encumbered asset or (ii) the amount of debt allocated to such Reference Asset, in the case of a transfer of a partnership interest. The transactions described in this Section 7.12(b) shall be taken into account in determining the Realized Tax Benefit or Realized Tax Detriment, as applicable, for such Taxable Year based on the income, gain or loss deemed allocated to the Corporate Taxpayer and its Subsidiaries using the Non-Blocker Transferred Basis, Non-Exchange Transferred Basis, Non-IPO Basis, Non-Stepped Up Tax Basis and Non-Unit Transferred Basis of the Reference Assets in calculating its Hypothetical Tax Liability for such Taxable Year and using the actual Tax basis of the Reference Assets in calculating its Actual Tax Liability, determined using the “with and without” methodology. Thus, for example, in determining the Hypothetical Tax Liability of the Corporate Taxpayer or its Subsidiaries the taxable income of the Corporate Taxpayer or its Subsidiaries shall be determined by treating OpCo as having sold the applicable Reference Asset for its fair market value, recovering any basis applicable to such Reference Asset (using the Non-Blocker Transferred Basis, Non-Exchange Transferred Basis, Non-IPO Basis, Non-Stepped Up Tax Basis and Non-Unit Transferred Basis), while the Actual Tax Liability of the Corporate Taxpayer or its Subsidiaries would be determined by recovering the actual Tax basis of the Reference Asset that reflects any Blocker Transferred Basis, Exchange Transferred Basis, IPO Basis, Basis Adjustments and Unit Transferred Basis. For purposes of this Section 7.12, a transfer of a partnership interest shall be treated as a transfer of the transferring partner’s share of each of the assets and liabilities of that partnership.

- 25 -

Section 7.13 Confidentiality.

(a) The Rights Holders and the Rights Holder Representative acknowledge and agree that the information of the Corporate Taxpayer is confidential and, except in the course of performing any duties as necessary for the Corporate Taxpayer, as required by law or legal process or to enforce the terms of this Agreement, shall keep and retain in confidence and not disclose to any Person any confidential matters of the Corporate Taxpayer acquired pursuant to this Agreement.

(b) This Section 7.13 shall not restrict (i) the disclosure of any information that has been made publicly available by the Corporate Taxpayer, becomes public knowledge (except as a result of an act of any Rights Holder, the Rights Holder Representative or any of their Affiliates in violation of this Agreement) or is generally known to the business community, (ii) the disclosure of information to its personnel and representatives who are subject to confidentiality obligations or otherwise to the extent reasonably necessary for any Rights Holder or its Affiliates to prepare and file its Tax Returns, to respond to any inquiries regarding the same from any Taxing Authority or to prosecute or defend any action, proceeding or audit by any Taxing Authority with respect to such Tax Returns or (iii) the disclosure of information to any direct or indirect current, former or prospective limited partners of any Rights Holder so long as such Persons are apprised of the confidential nature thereof. Notwithstanding anything to the contrary in this Agreement, each Rights Holder (and each employee, representative or other agent of such Rights Holder, as applicable) may disclose the tax treatment and tax structure of (A) the Corporate Taxpayer, (B) the transactions, if any, entered into in connection with this Agreement, (C) this Agreement, and (D) any of the transactions of the Corporate Taxpayer, and all materials of any kind (including opinions or other tax analyses) that are provided to the Rights Holders relating to such tax treatment and tax structure.

Section 7.14 Rules of Construction. Unless otherwise specified herein:

(a) For purposes of interpretation of this Agreement:

Section 7.15 Rights Holder Representative. By executing this Agreement, each of the Rights Holders shall be deemed to have irrevocably constituted the Rights Holder Representative as his, her or its agent, proxy and attorney in fact with full power of substitution to act from and after the date hereof and to do any and all things and execute any and all documents on behalf of such Rights Holders which may be necessary, convenient or appropriate to facilitate any matters under this Agreement, including: (i) execution of the documents and certificates required pursuant to this Agreement; (ii) except to the extent specifically provided in this Agreement, receipt and forwarding of notices and communications pursuant to this Agreement; (iii) administration of the provisions of this Agreement; (iv) any and all consents, waivers, amendments or modifications deemed by the Rights Holder Representative, in its sole and absolute discretion, to be necessary or appropriate under this Agreement (including a termination of the Corporate Taxpayer’s obligations) and the execution or delivery of any documents that may be necessary or appropriate in connection therewith; (v) amending this Agreement or any of the instruments to be delivered to the Corporate Taxpayer pursuant to this Agreement; (vi) taking actions the Rights Holder Representative is expressly authorized to take pursuant to the other provisions of this Agreement; (vii) negotiating and compromising, on behalf of such Rights Holders, any dispute that may arise under, and exercising or refraining from exercising any remedies available under, this Agreement or any other agreement contemplated hereby and executing, on behalf of such Rights Holders, any settlement agreement, release or other document with respect to such dispute or remedy; and (viii) engaging attorneys, accountants, agents or consultants on behalf of such Rights Holders in connection with this Agreement or any other agreement contemplated hereby and paying any fees related thereto. The Rights Holder Representative may resign upon thirty (30) calendar days’ written notice to the Corporate Taxpayer. All reasonable and documented out-of-pocket costs and expenses incurred by the Rights Holder Representative in its capacity as such shall be promptly reimbursed by the Corporate Taxpayer upon presentation of an invoice and reasonable support therefor by the Rights Holder Representative. To the fullest extent permitted by law, none of the Rights Holder Representative, any of its Affiliates, or any of the Rights Holder Representative’s or Affiliate’s directors, officers, employees or other agents (each a “Covered Person”) shall be liable, responsible or accountable in damages or otherwise to any Rights Holder, OpCo or the Corporate Taxpayer for damages arising from any action taken or omitted to be taken by the Rights Holder Representative or any other Person with respect to OpCo or the Corporate Taxpayer, except in the case of any action or omission which constitutes, with respect to such Person, willful misconduct or fraud, and each Rights Holder shall indemnify, defend and hold harmless the Rights Holder Representative for any losses, liabilities or damages arising out of the Rights Holder Representative’s performance of its duties hereunder. Each of the Covered Persons may consult with legal counsel, accountants and other experts selected by it, and any act or omission suffered or taken by it on behalf of the Rights Holders or in furtherance of

- 27 -

the interest of the Rights Holders in good faith in reliance upon and in accordance with the advice of such counsel, accountants or other experts shall create a rebuttable presumption of the good faith and due care of such Covered Person with respect to such act or omission; provided that such counsel, accountants or other experts were selected with reasonable care. Each of the Covered Person may rely in good faith upon, and shall have no liability to OpCo, the Corporate Taxpayer or the Rights Holders for acting or refraining from acting upon, any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture or other paper or document reasonably believed by it to be genuine and to have been signed or presented by the proper party or parties. Each Rights Holders irrevocably agrees that such agency is coupled with an interest and is therefore irrevocable without the written consent of the Rights Holder Representative and will survive the death, incapacity, dissolution, liquidation or bankruptcy of such Rights Holder.

Section 7.16 Partnership Agreement. To the extent this Agreement imposes obligations on OpCo or a member of OpCo, this Agreement shall be treated as part of the OpCo Agreement as described in Section 761(c) of the Code and Sections 1.704-1(b)(2)(ii)(h) and 1.761-1(c) of the Treasury Regulations.

Section 7.17 Specific Performance. The parties hereto agree that irreparable damage, for which monetary relief, even if available, would not be an adequate remedy, would occur in the event that any provision of this Agreement is not performed in accordance with its specific terms or is otherwise breached, including if the parties hereto fail to take any action required of them hereunder to consummate any of the transactions contemplated by this Agreement. It is accordingly agreed that (i) the parties hereto shall be entitled to an injunction or injunctions, specific performance or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement and to thereafter cause the transactions contemplated by this Agreement to be consummated, and (ii) the right of specific performance and other equitable relief is an integral part of the transactions contemplated by this Agreement and without that right, no party hereto would have entered into this Agreement. The parties hereto agree not to assert that a remedy of specific performance or other equitable relief is unenforceable, invalid, contrary to law or inequitable for any reason, and not to assert that a remedy of monetary damages would provide an adequate remedy or that the parties otherwise have an adequate remedy at law. The parties hereto acknowledge and agree that any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 7.17 shall not be required to provide any bond or other security in connection with any such order or injunction.

Section 7.18 Certain Acknowledgments. Without limiting the generality of Section 2.4, any Person who or which accepts the rights and obligations of a Rights Holder under this Agreement shall be treated as a Rights Holder hereunder pursuant to the terms hereof, and such Person shall be deemed to have adhered to and agreed to be bound by the terms of this Agreement as a Rights Holder without further action or the execution of any additional documents or instruments, including any counterpart signature page to this Agreement or joinder to this Agreement. Further, each such Person shall be deemed to have agreed not to assert any claim that it is not bound by the terms of this Agreement and acknowledges that in no circumstance can such Person be a Rights Holder, or be entitled to the rights of a Rights Holder hereunder, if it is not bound by all of the terms and conditions of this Agreement, including, without limitation, the obligations to which a Rights Holder is subject hereunder.
