WHEREAS, the parties to this Agreement desire to make certain arrangements with respect to the effect of the Basis Adjustment and Imputed Interest on the actual liability for Taxes of the Corporate Taxpayer.

NOW, THEREFORE, in consideration of the foregoing and the respective covenants and agreements set forth herein, and intending to be legally bound hereby, the parties hereto agree as follows:

Article I

DEFINITIONS

Section 1.01 Definitions.

(a) The following terms shall have the following meanings for the purposes of this Agreement:

“Actual Tax Liability” means, with respect to any Taxable Year, the actual liability for U.S. federal, state and local income Taxes of (i) the Corporate Taxpayer and (ii) without duplication, OpCo, but only with respect to Taxes imposed on OpCo and allocable to the Corporate Taxpayer (or to any other member of the consolidated group, if any, of which the Corporate Taxpayer is the parent) for such Taxable Year.

“Affiliate” means, with respect to any Person, any other Person that directly or indirectly, through one or more intermediaries, Controls, is Controlled by, or is under common Control with, such Person.

“Agreed Rate” means a per annum rate of LIBOR plus 100 basis points.

“Applicable Member” means any Member to whom or which any portion of a Realized Tax Benefit may be Attributable under this Agreement.

A Net Tax Benefit is “Attributable” to a Member to the extent that it is derived from any Basis Adjustment or Imputed Interest that is attributable to an Exchange undertaken by or with respect to such Member, and portions of any Realized Tax Detriment shall be Attributed to Members under similar principles. If a Person becomes a Member pursuant to ‎Section 7.02(b), each reference to such Member in the immediately preceding sentence shall include a reference to such Member’s predecessors in interest, but only to the extent commensurate with the rights hereunder transferred, directly or indirectly, to such Member by such predecessors, and, if any such predecessor in interest continues as a Member, the preceding sentence shall be applied to such predecessor as though, to the extent commensurate with the rights hereunder transferred by such predecessor, such predecessor had never been a Member.

“Basis Adjustment” means the adjustment to the tax basis of a Reference Asset under Sections 732, 755 and 1012 of the Code and the Treasury Regulations promulgated thereunder (in situations where, as a result of one or more Exchanges, OpCo

becomes an entity that is disregarded as separate from its owner for U.S. federal income tax purposes) or under Sections 743(b) and 755 of the Code and the Treasury Regulations promulgated thereunder (in situations where, following an Exchange, OpCo remains in existence as an entity for U.S. federal income tax purposes) and, in each case, comparable sections of state and local tax laws, as a result of (i) an Exchange and (ii) the payments made pursuant to the Tax Receivable Agreements. For the avoidance of doubt, the amount of any Basis Adjustment resulting from an Exchange of one or more Common Units shall be determined without regard to any Pre- Exchange Transfer of such Common Units and as if any such Pre-Exchange Transfer had not occurred.

A “Beneficial Owner” of a security is a Person who directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, has or shares: (i) voting power, which includes the power to vote, or to direct the voting of, such security and/or (ii) investment power, which includes the power to dispose of, or to direct the disposition of, such security.

“Blended Rate” means, with respect to any Taxable Year, the sum of the effective rates of tax imposed on the aggregate net income of the Corporate Taxpayer in each state or local jurisdiction in which the Corporate Taxpayer files Tax Returns for such Taxable Year, with the maximum effective rate in any state or local jurisdiction being equal to the product of: (i) the apportionment factor on the income or franchise Tax Return filed by the Corporate Taxpayer in such jurisdiction for such Taxable Year, and (ii) the maximum applicable corporate tax rate in effect in such jurisdiction in such Taxable Year. As an illustration of the calculation of Blended Rate for a Taxable Year, if the Corporate Taxpayer solely files Tax Returns in State 1 and State 2 in a Taxable Year, the maximum applicable corporate tax rates in effect in such states in such Taxable Year are 6% and 5%, respectively and the apportionment factors for such states in such Taxable Year are 60% and 40%, respectively, then the Blended Rate for such Taxable Year is equal to 5.6% (i.e., 6% times 60% plus 5% times 40%).

“Board” means the board of directors of the Corporate Taxpayer.

“Business Day” shall have the meaning ascribed to such term in the LLC Agreement.

“Change of Control” means the occurrence of any of the following events:

(ii) the following individuals cease to constitute a majority of the number of directors of the Corporate Taxpayer then serving: individuals who, on the IPO Date, constitute the Board and any new director whose appointment or election by the Board or nomination for election by the Corporate Taxpayer’s shareholders was approved or recommended by a vote of at least a majority of the directors then still in office who either were directors on the IPO Date or whose appointment, election or nomination for election was previously so approved or recommended by the directors referred to in this clause (ii);

(iii) there is consummated a merger or consolidation of the Corporate Taxpayer with any other corporation or other entity, and, immediately after the consummation of such merger or consolidation, either (x) the Board immediately prior to the merger or consolidation does not constitute at least a majority of the board of directors of the company surviving the merger or, if the surviving company is a Subsidiary, the ultimate parent thereof, or (y) the voting securities of the Corporate Taxpayer immediately prior to such merger or consolidation do not continue to represent or are not converted into more than 50% of the combined voting power of the then outstanding voting securities of the Person resulting from such merger or consolidation or, if the surviving company is a Subsidiary, the ultimate parent thereof; or

(iv) the shareholders of the Corporate Taxpayer approve a plan of complete liquidation or dissolution of the Corporate Taxpayer or there is consummated an agreement or series of related agreements for the sale or other disposition, directly or indirectly, by the Corporate Taxpayer of all or substantially all of the Corporate Taxpayer’s assets, other than such sale or other disposition by the Corporate Taxpayer of all or substantially all of the Corporate Taxpayer’s assets to an entity, at least 50% of the combined voting power of the voting securities of which are owned by shareholders of the Corporate Taxpayer in substantially the same proportions as their ownership of the Corporate Taxpayer immediately prior to such sale.

Notwithstanding the foregoing, except with respect to clause (ii) and clause (iii) above, a “Change of Control” shall not be deemed to have occurred by virtue of the consummation of any transaction or series of integrated transactions immediately following which the record holders of the shares of the Corporate Taxpayer immediately prior to such transaction or series of transactions continue to have substantially the same proportionate ownership in, and own substantially all of the shares of, an entity which owns all or substantially all of the assets of the Corporate Taxpayer immediately following such transaction or series of transactions.

The Realized Tax Benefit and Realized Tax Detriment for each Taxable Year shall be determined based on the most recent Tax Benefit Schedule or Amended Schedule, if any, in existence at the time of such determination.

“Default Rate” means a per annum rate of LIBOR plus 500 basis points.

“Determination” shall have the meaning ascribed to such term in Section 1313(a) of the Code or similar provision of state and local tax law, as applicable, or any other event (including the execution of IRS Form 870-AD) that finally and conclusively establishes the amount of any liability for Tax and shall also include the acquiescence of the Corporate Taxpayer to the amount of any assessed liability for Tax.

“LLC Agreement” means the Amended and Restated Limited Liability Company Agreement of OpCo, dated as of the date hereof.

“Market Value” shall mean the closing price of the Class A Common Stock on the applicable Exchange Date on the national securities exchange or interdealer quotation system on which such Class A Common Stock is then traded or listed, as reported by the Wall Street Journal; provided, that if the closing price is not reported by the Wall Street Journal for the applicable Exchange Date, then the Market Value shall mean the closing price of the Class A Common Stock on the Business Day immediately preceding such Exchange Date on the national securities exchange or interdealer quotation system on which such Class A Common Stock is then traded or listed, as reported by the Wall Street Journal; provided, further, that if the Class A Common Stock is not then listed on a national securities exchange or interdealer quotation system, the Market Value shall mean the cash consideration paid for Class A Common Stock, or the fair market value of the other property delivered for Class A Common Stock, as determined by the Board in good faith.

Article II

DETERMINATION OF REALIZED TAX BENEFIT

Section 2.01 Basis Adjustment. Within 120 calendar days after the filing of the federal income tax return of the Corporate Taxpayer for each Taxable Year in which any Exchange has been effected by any Member, the Corporate Taxpayer shall deliver to each such Member a schedule (the “Exchange Basis Schedule”) that shows, in reasonable detail necessary to perform the calculations required by this Agreement, including with respect to each Exchanging party, (i) the Non-Stepped Up Tax Basis of the Reference Assets as of each applicable Exchange Date, (ii) the Basis Adjustments with respect to the Reference Assets as a result of each Exchange effected in such Taxable Year, calculated (x) in the aggregate, and (y) solely with respect to Exchanges by such Member, (iii) the period (or periods) over which the Reference Assets are amortizable and/or depreciable and (iv) the period (or periods) over which each Basis Adjustment is amortizable and/or depreciable. For the avoidance of doubt, payments made under this Agreement shall not be treated as resulting in a Basis Adjustment to the extent such payments are treated as Imputed Interest.

Section 2.02 Realized Tax Benefit and Realized Tax Detriment.

(a) Tax Benefit Schedule. Within 120 calendar days after the filing of the U.S. federal income tax return of the Corporate Taxpayer for any Taxable Year in which any Exchange has been effected by a Member or which is subsequent to any Taxable Year in which any Exchange has been effected by a Member, the Corporate Taxpayer shall provide to such Member a schedule showing, in reasonable detail, the calculation of the Realized Tax Benefit or Realized Tax Detriment and the portion Attributable to such Member for such Taxable Year (a “Tax Benefit Schedule”). The Tax Benefit Schedule will become final as provided in ‎Section 2.03(a) and may be amended as provided in ‎Section 2.03(b) (subject to the procedures set forth in ‎Section 2.03(b)).

(b) Applicable Principles. The Realized Tax Benefit or Realized Tax Detriment for each Taxable Year is intended to measure the decrease or increase in the Actual Tax Liability of the Corporate Taxpayer for such Taxable Year attributable to

the Basis Adjustments and Imputed Interest, determined using a “with and without” methodology. For the avoidance of doubt, the Actual Tax Liability will take into account the deduction of the portion of the Tax Benefit Payment that must be accounted for as interest under the Code based upon the characterization of Tax Benefit Payments as additional consideration payable by the Corporate Taxpayer for the Common Units acquired in an Exchange. Carryovers or carrybacks of any Tax item attributable to the Basis Adjustment or Imputed Interest shall be considered to be subject to the rules of the Code and the Treasury Regulations or the appropriate provisions of U.S. state and local income and franchise tax law, as applicable, governing the use, limitation and expiration of carryovers or carrybacks of the relevant type. If a carryover or carryback of any Tax item includes a portion that is attributable to the Basis Adjustment or Imputed Interest and another portion that is not, such portions shall be considered to be used in accordance with the “with and without” methodology. The parties agree that (i) all Tax Benefit Payments attributable to the Basis Adjustments (other than amounts accounted for as interest under the Code) will (A) be treated as subsequent upward purchase price adjustments that give rise to further Basis Adjustments to Reference Assets for the Corporate Taxpayer and (B) have the effect of creating additional Basis Adjustments to Reference Assets for the Corporate Taxpayer in the year of payment, and (ii) as a result, such additional Basis Adjustments will be incorporated into the current year calculation and into future year calculations, as appropriate.

Section 2.03 Procedures, Amendments.

(a) Procedure. Every time the Corporate Taxpayer delivers to a Member an applicable Schedule under this Agreement, including any Amended Schedule delivered pursuant to ‎Section 2.03(b) and any Early Termination Schedule or amended Early Termination Schedule, the Corporate Taxpayer shall also (x) deliver to such Member schedules and work papers, as determined by the Corporate Taxpayer or requested by such Member, providing reasonable detail regarding the preparation of the Schedule and (y) allow such Member reasonable access to the appropriate representatives at the Corporate Taxpayer, as determined by the Corporate Taxpayer, in connection with a review of such Schedule. Without limiting the application of the preceding sentence, each time the Corporate Taxpayer delivers to a Member a Tax Benefit Schedule, in addition to the Tax Benefit Schedule duly completed, the Corporate Taxpayer shall deliver to such Member the Corporate Taxpayer Return, the reasonably detailed calculation by the Corporate Taxpayer of the Hypothetical Tax Liability, the reasonably detailed calculation by the Corporate Taxpayer of the Actual Tax Liability, as well as any other work papers as determined by the Corporate Taxpayer or requested by such Member, provided that the Corporate Taxpayer shall be entitled to redact any information that it reasonably believes is unnecessary for purposes of determining the items in the applicable Schedule or amendment thereto. An applicable Schedule or amendment thereto shall become final and binding on the applicable Member and the Corporate Taxpayer thirty (30) calendar days from the first date on which the Member has received the applicable Schedule or amendment thereto unless such Member (i) within thirty (30) calendar days after receiving an applicable Schedule or amendment thereto, provides the Corporate Taxpayer with notice of a material objection to such Schedule (“Objection Notice”) made in good faith or (ii) provides a written waiver of such right of any

Objection Notice within the period described in clause ‎(i) above, in which case such Schedule or amendment thereto becomes binding on the date the waiver is received by the Corporate Taxpayer. If the applicable Member and the Corporate Taxpayer for any reason, are unable to successfully resolve the issues raised in the Objection Notice within thirty (30) calendar days after receipt by the Corporate Taxpayer of an Objection Notice, the Corporate Taxpayer and the applicable Member shall employ the reconciliation procedures as described in ‎Section 7.09 (the “Reconciliation Procedures”).

(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 inaccuracies in the Schedule 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 applicable Member, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, (iv) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to a carryback or carryforward of a loss or other tax item to such Taxable Year, (v) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year, or ((vi) to adjust the Exchange Basis Schedule to take into account payments made pursuant to this Agreement (any such Schedule, an “Amended Schedule”). The Corporate Taxpayer shall provide an Amended Schedule to each relevant Member within thirty (30) calendar days of the occurrence of an event referenced in clauses ‎(i) through ‎(vi) of the preceding sentence.

Article III

TAX BENEFIT PAYMENTS

Section 3.01 Payments.

(a) Within five (5) Business Days after all of the Tax Benefit Schedules (as defined in each of the Tax Receivable Agreements) with respect to a Taxable Year delivered to any Member become final in accordance with ‎Section 2.03(a), the Corporate Taxpayer shall pay to each Member for such Taxable Year the Tax Benefit Payment in the amount determined pursuant to ‎Section 3.01(b). Each such Tax Benefit Payment to a Member shall be made by wire transfer of immediately available funds to the bank account previously designated by such Member to the Corporate Taxpayer or as otherwise agreed by the Corporate Taxpayer and such Member. For the avoidance of doubt, no Tax Benefit Payment shall be made in respect of estimated tax payments, including federal estimated income tax payments.

Notwithstanding any provision of this Agreement to the contrary, any Member may elect with respect to any Exchange to limit the aggregate Tax Benefit Payments made to such Member in respect of any such Exchange to a specified percentage of the amount equal to the sum of (A) the cash, excluding any Tax Benefit Payments, and (B) the Market Value of the Class A Shares received by such Member on such Exchange (or such other limitation selected by the Member and consented to by the Corporate Taxpayer, which

consent shall not be unreasonably withheld). The Member shall exercise its rights under the preceding sentence by notifying the Corporate Taxpayer in writing of its desire to impose such a limit and the specified percentage (or such other limitation selected by the Member) and such other details as may be necessary (including whether such limit includes the Imputed Interest in respect of any such Exchange) in such manner and at such time (but in no event later than the date of any such Exchange) as reasonably directed by the Corporate Taxpayer; provided, however, that, in the absence of such direction, the Member shall give such written notice in the same manner as is required by ‎Section 7.01 of this Agreement contemporaneously with Member’s notice to the Corporate Taxpayer of the applicable Exchange.

(b) A “Tax Benefit Payment” means, with respect to a Member, an amount, not less than zero, equal to the sum of the amount of the Net Tax Benefit Attributable to such Member and the related Interest Amount. For the avoidance of doubt, for Tax purposes, the Interest Amount shall not be treated as interest but instead shall be treated as additional consideration for the acquisition of Common Units in Exchanges, unless otherwise required by law. Subject to ‎Section 3.03(a), 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 Tax Benefit Payments previously made under this ‎Section 3.01 (excluding payments attributable to Interest Amounts); provided, for the avoidance of doubt, that such Member shall not be required to return any portion of any previously made Tax Benefit Payment. The “Interest Amount” shall equal the interest on the amount of the Net Tax Benefit Attributable to such Member calculated at the Agreed Rate from the due date (without extensions) for filing the Corporate Taxpayer Return with respect to Taxes for such Taxable Year until the Payment Date of the applicable Tax Benefit Payment. Notwithstanding anything to the contrary in this Agreement, after any lump-sum payment under ‎Article IV of this Agreement in respect of present or future Tax attributes subject to this Agreement, the Tax Benefit Payment, Net Tax Benefit and components thereof shall be calculated without taking into account any such attributes or any such lump-sum payment.

Section 3.02 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. The provisions of this Agreement shall be construed in the appropriate manner to ensure such intentions are realized.

Section 3.03 Pro Rata Payments.

(a) Notwithstanding anything in ‎Section 3.01 to the contrary, to the extent that the aggregate tax benefit of the Corporate Taxpayer’s reduction in Tax liability as a result of the Basis Adjustments and Imputed Interest under this Agreement is limited in a particular Taxable Year because the Corporate Taxpayer does not have sufficient taxable income to fully utilize available deductions and other attributes, the limitation on the tax benefit for the Corporate Taxpayer shall be allocated among the Members in proportion to the respective amounts of Tax Benefit Payments that would have been determined under this Agreement if the Corporate Taxpayer had sufficient

taxable income so that there were no such limitation; provided, that for purposes of allocating among the Members the aggregate Tax Benefit Payments under this Agreement with respect to any Taxable Year, the operation of this ‎Section 3.03(a) with respect to any prior Taxable Year shall be taken into account, it being the intention of the Corporate Taxpayer and the Members for each Member to receive, in the aggregate, Tax Benefit Payments in proportion to the aggregate Net Tax Benefits Attributable to such Member had this ‎Section 3.03(a) never operated.

(b) After taking into account ‎Section 3.03(a), 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 Members agree that (i) the Corporate Taxpayer shall pay the same proportion of each Tax Benefit Payment due under this Agreement in respect of such Taxable Year, without favoring one obligation over the other, and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year until all Tax Benefit Payments in respect of prior Taxable Years have been made in full.

(c) To the extent the Corporate Taxpayer makes a payment to a Member in respect of a particular Taxable Year under ‎Section 3.01(a) of this Agreement (taking into account ‎Section 3.03(a) and ‎(b), but excluding payments attributable to Interest Amounts) in excess of the amount of such payment that should have been made to such Member in respect of such Taxable Year, then (i) such Member shall not receive further payments under ‎Section 3.01(a) until such Member has foregone an amount of payments equal to such excess and (ii) the Corporate Taxpayer shall pay the amount of such Member’s foregone payments to the other Members in a manner such that each of the other Members, to the maximum extent possible, shall have received aggregate payments under ‎Section 3.01(a) of this Agreement (excluding payments attributable to Interest Amounts) in the amount it would have received if there had been no excess payment to such Member.

Article IV

TERMINATION

Section 4.01 Termination, Early Termination and Breach of Agreement.

(a) Unless terminated earlier pursuant to ‎Section 4.01(b), ‎Section 4.01(c) or ‎Section 4.01(d), this Agreement will terminate when there is no further potential for a Tax Benefit Payment pursuant to this Agreement. Tax Benefit Payments under this Agreement are not conditioned on any Member retaining an interest in the Corporate Taxpayer or OpCo (or any successor thereto).

(b) The Corporate Taxpayer may terminate this Agreement with respect to all amounts payable to the Members and with respect to all of the Common Units held (or previously held and Exchanged) by all Members at any time by paying to each Member the Early Termination Payment in respect of such Member; provided,

however, that this Agreement shall only terminate pursuant to this ‎Section 4.01(b) upon the receipt of the Early Termination Payment by all Members; and provided, further, that the Corporate Taxpayer may withdraw any notice to exercise its termination rights under this ‎Section 4.01(b) prior to the time at which any Early Termination Payment has been paid. Upon payment of the Early Termination Payment by the Corporate Taxpayer in accordance with this ‎Section 4.01(b), neither the Members nor the Corporate Taxpayer shall have any further payment obligations under this Agreement, other than for any (i) Tax Benefit Payment agreed to by the Corporate Taxpayer and a Member as due and payable but unpaid as of the Early Termination Notice and (ii) Tax Benefit Payment due for the Taxable Year ending with or including the date of the Early Termination Notice (except to the extent that the amount described in clause (ii) is included in the Early Termination Payment). If an Exchange occurs after the Corporate Taxpayer makes the Early Termination Payment pursuant to this ‎Section 4.01(b), the Corporate Taxpayer shall have no obligations under this Agreement with respect to such Exchange.

(c) In the event of a Change of Control, all payment obligations hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the effective date of the Change of Control and shall include, but not be limited to, (x) the Early Termination Payment calculated as if an Early Termination Notice had been delivered on the effective date of the Change of Control, (y) any Tax Benefit Payment agreed to by the Corporate Taxpayer and any Members as due and payable but unpaid as of the effective date of the Change of Control, and (z) without duplication, any Tax Benefit Payment not yet due for any Taxable Year ending prior to, with or including the effective date of the Change of Control; provided that procedures similar to the procedures of ‎Section 4.02 shall apply with respect to the determination of the amount payable by the Corporate Taxpayer pursuant to this sentence. In the event of a Change of Control, the Early Termination Payment shall be calculated utilizing the Valuation Assumptions and by substituting, in each case, the phrase “the effective date of the Change of Control” for the term “Early Termination Date.”

(d) In the event that the Corporate Taxpayer breaches any of its material obligations under this Agreement, whether as a result of failure to make any payment when due, failure to honor any other material obligation required hereunder or by operation of law as a result of the rejection of this Agreement in a case commenced under the Bankruptcy Code or otherwise, then all obligations hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such breach and shall include, but not be limited to, (x) the Early Termination Payment calculated as if an Early Termination Notice had been delivered on the date of a breach, (y) any Tax Benefit Payment agreed to by the Corporate Taxpayer and any Members as due and payable but unpaid as of the date of a breach, and (z) without duplication, any Tax Benefit Payment not yet due for the Taxable Year ending with or including the date of a breach; provided that procedures similar to the procedures of ‎Section 4.02 shall apply with respect to the determination of the amount payable by the Corporate Taxpayer pursuant to this sentence. Notwithstanding the foregoing, in the event that the Corporate Taxpayer breaches this Agreement, each Member shall be entitled to elect to receive the amounts set forth in

clauses (x), (y) and (z) above or to seek specific performance of the terms hereof. The parties agree that the failure to make any payment due pursuant to this Agreement within three 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, and that it will not be considered to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within three months of the date such payment is due. Notwithstanding anything in this Agreement to the contrary, it shall not be a breach of this Agreement if the Corporate Taxpayer fails to make any payment due pursuant to this Agreement when due to the extent the Corporate Taxpayer has insufficient funds to make such payment despite using reasonable best efforts to obtain funds to make such payment (including by causing OpCo or any other Subsidiaries to distribute or lend funds for such payment); provided that the interest provisions of ‎Section 5.02 shall apply to such late payment (unless the Corporate Taxpayer does not have sufficient cash to make such payment as a result of limitations imposed by debt agreements to which the Corporate Taxpayer or any of its Subsidiaries is a party, in which case ‎Section 5.02 shall apply, but the Default Rate shall be replaced by the Agreed Rate); provided, further, that the Corporate Taxpayer shall promptly (and in any event, within two (2) Business Days), pay all such unpaid payments, together with accrued and unpaid interest thereon, immediately following such time that the Corporate Taxpayer has, and to the extent the Corporate Taxpayer has, sufficient funds to make such payment, and the failure of the Corporate Taxpayer to do so shall constitute a breach of this Agreement. For the avoidance of doubt, all cash and cash equivalents used or to be used to pay dividends by, or repurchase equity securities of, the Corporate Taxpayer shall be deemed to be funds sufficient and available to pay such unpaid payments, together with any accrued and unpaid interest thereon.

Section 4.02 Early Termination Notice. If the Corporate Taxpayer chooses to exercise its right of early termination under ‎Section 4.01(b) above, the Corporate Taxpayer shall deliver to each Member notice of such intention to exercise such right (“Early Termination Notice”) and a schedule (the “Early Termination Schedule”) specifying the Corporate Taxpayer’s intention to exercise such right and showing in reasonable detail the calculation of the Early Termination Payment for such Member. The Early Termination Schedule shall become final and binding on such Member thirty (30) calendar days from the first date on which such Member has received such Schedule or amendment thereto unless such Member (i) within thirty (30) calendar days after receiving the Early Termination Schedule, provides the Corporate Taxpayer with notice of a material objection to such Schedule made in good faith (“Material Objection Notice”) or (ii) provides a written waiver of such right of a Material Objection Notice within the period described in clause ‎(i) above, in which case such Schedule becomes binding on the date the waiver is received by the Corporate Taxpayer (such thirty (30) calendar day date as modified, if at all, by clauses ‎(i) or ‎(ii), the “Early Termination Effective Date”). If the Corporate Taxpayer and such Member, for any reason, are unable to successfully resolve the issues raised in such notice within thirty (30) calendar days after receipt by the Corporate Taxpayer of the Material Objection Notice, the Corporate Taxpayer and such Member shall employ the Reconciliation Procedures.

Section 4.03 Payment upon Early Termination.

(a) Within three (3) Business Days after the Early Termination Effective Date, the Corporate Taxpayer shall pay to each Member an amount equal to the Early Termination Payment in respect of such Member. Such payment shall be made by wire transfer of immediately available funds to a bank account or accounts designated by such Member or as otherwise agreed by the Corporate Taxpayer and such Member.

(b) “Early Termination Payment” in respect of a Member shall equal the present value, discounted at the Early Termination Rate as of the Early Termination Effective Date, of all Tax Benefit Payments in respect of such Member that would be required to be paid by the Corporate Taxpayer beginning from the Early Termination Date and assuming that the Valuation Assumptions are applied.

Article V

SUBORDINATION AND LATE PAYMENTS

Section 5.01 Subordination. Notwithstanding any other provision of this Agreement to the contrary, any Tax Benefit Payment or Early Termination Payment required to be made by the Corporate Taxpayer to any Member under this Agreement shall rank subordinate and junior in right of payment to any principal, interest or other amounts due and payable in respect of any obligations in respect of indebtedness for borrowed money of the Corporate Taxpayer and its Subsidiaries (“Senior Obligations”) and shall rank pari passu with all current or future unsecured obligations of the Corporate Taxpayer that are not Senior Obligations.

Section 5.02 Late Payments by the Corporate Taxpayer. The amount of all or any portion of any Tax Benefit Payment or Early Termination Payment not made to the applicable Member when due under the terms of this Agreement shall be payable together with any interest thereon, computed at the Default Rate and commencing from the date on which such Tax Benefit Payment or Early Termination Payment was due and payable, subject to ‎Section 4.01(d).

Article VI

NO DISPUTES; CONSISTENCY; COOPERATION

Section 6.01 Participation in the Corporate Taxpayer’s and OpCo’s Tax Matters. Except as otherwise provided herein, the Corporate Taxpayer shall have full responsibility for, and sole discretion over, Tax matters concerning the Corporate Taxpayer and OpCo, including the preparation, filing or amending of any Tax Return. Notwithstanding the foregoing, the Corporate Taxpayer shall notify a Member of, and keep such Member reasonably informed with respect to, the portion of any audit, examination, or any other administrative or judicial proceeding (a “Tax Proceeding”) of the Corporate Taxpayer and OpCo by a Taxing Authority the outcome of which is

reasonably expected to affect the rights and obligations of such Member under this Agreement, and shall provide to such Member reasonable opportunity to provide information and other input (at such Member’s own expense) to the Corporate Taxpayer, OpCo and their respective advisors concerning the conduct of (but, for the avoidance of doubt, such Member may not control) any such portion of such Tax Proceeding. In addition, the Corporate Taxpayer shall not, without the prior consent of the Continuing LLC Owner (such consent not to be unreasonably withheld, conditioned or delayed), settle any Tax Proceeding in a manner that would affect in any material respect the amounts payable to the Members under this Agreement; provided, however, that the Corporate Taxpayer and OpCo shall not be required to take any action that is inconsistent with any provision of the LLC Agreement.

Section 6.02 Consistency. The Corporate Taxpayer and the Members agree to report and cause to be reported for all purposes, including federal, state and local Tax purposes and financial reporting purposes, all Tax-related items (including the Basis Adjustments and each Tax Benefit Payment) in a manner consistent with that 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. Any dispute as to required Tax or financial reporting shall be subject to ‎Section 7.09.

Section 6.03 Cooperation. Each of the Corporate Taxpayer and each Member 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 any determination or computation necessary or appropriate under this Agreement, preparing any Tax Return or contesting or defending any audit, examination or controversy with any Taxing Authority, (b) make itself available to the other party and its representatives to provide explanations of documents and materials and such other information as the other 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, and the Corporate Taxpayer shall reimburse the applicable Member for any reasonable third-party costs and expenses incurred pursuant to this ‎Section 6.03.

The Corporate Taxpayer shall require and cause any direct or indirect successor (whether by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Corporate Taxpayer, by written agreement, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Corporate Taxpayer would be required to perform if no such succession had taken place.

Section 7.03 Resolution of Disputes.

(a) Except for Reconciliation Disputes subject to ‎Section 7.09, any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation,

If the parties to the Dispute fail to agree on the selection of an arbitrator within ten (10) days of the receipt of the request for arbitration, the International Chamber of Commerce shall make the appointment. The arbitrator shall be a lawyer admitted to the practice of law in the State of Delaware and shall conduct the proceedings in the English language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

The parties acknowledge that the fora designated by this paragraph ‎(c) have a reasonable relation to this Agreement, and to the parties’ relationship with one another.

(d) The parties hereby waive, to the fullest extent permitted by applicable law, any objection which they now or hereafter may have to personal jurisdiction or to the laying of venue of any such ancillary suit, action or proceeding

brought in any court referred to in the preceding paragraph of this ‎Section 7.03 and such parties agree not to plead or claim the same.

Section 7.04 Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Until and unless each party has received a counterpart hereof signed by the other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

Section 7.05 Entire Agreement. This Agreement [and the other Reorganization Documents]² (as such term is defined in the LLC Agreement) constitute the entire agreement between the parties with respect to the subject matter of this Agreement and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter of this Agreement. Nothing in this Agreement shall create any third-party beneficiary rights in favor of any Person or other party hereto.

Section 7.06 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the fullest extent possible.

Section 7.07 Amendment. No provision of this Agreement may be amended unless such amendment is approved in writing by the Corporate Taxpayer and by Persons who would be entitled to receive at least two-thirds of the Early Termination Payments payable to all Persons entitled to Early Termination Payments under this Agreement if the Corporate Taxpayer had exercised its right of early termination on the date of the most recent Exchange prior to such amendment (excluding, for purposes of this sentence, all payments made to any Persons pursuant to this Agreement since the date of such most recent Exchange); provided, that no such amendment shall be effective if such amendment will have a disproportionate effect on the payments certain Persons will or may receive under the Tax Receivable Agreements unless all such Persons disproportionately affected consent in writing to such amendment. No provision of this Agreement may be waived unless such waiver is in writing and signed by the party against whom the waiver is to be effective.

Section 7.08 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the

²Note to Draft: To be confirmed.

conflicts of law rules of such State that would result in the application of the laws of any other State.

Section 7.09 Reconciliation. In the event that the Corporate Taxpayer and a Member are unable to resolve a disagreement with respect to the matters governed by Sections ‎2.03, ‎3.01(b), ‎4.02 and ‎6.02 within the relevant period designated in this Agreement (“Reconciliation Dispute”), the Reconciliation Dispute shall be submitted for determination to a nationally recognized expert (the “Expert”) in the particular area of disagreement mutually acceptable to both parties. The Expert shall be a partner or principal in a nationally recognized accounting or law firm, and unless the Corporate Taxpayer and such Member agree otherwise, the Expert shall not, and the firm that employs the Expert shall not, have any material relationship with the Corporate Taxpayer or such Member or other actual or potential conflict of interest. If the parties are unable to agree on an Expert within fifteen (15) calendar days of receipt by the respondent(s) of written notice of a Reconciliation Dispute, the Expert shall be appointed by the International Chamber of Commerce Centre for Expertise. The Expert shall resolve any matter relating to the Exchange Basis Schedule or an amendment thereto or the Early Termination Schedule or an amendment thereto within thirty (30) calendar days and shall resolve any matter relating to a Tax Benefit Schedule or an amendment thereto within fifteen (15) calendar days or as soon thereafter as is reasonably practicable, in each case after the matter has been submitted to the Expert for resolution. Notwithstanding the preceding sentence, if the matter is not resolved before any payment that is the subject of a disagreement would be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement is due, the undisputed amount shall be paid 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 amending any Tax Return shall be borne by the Corporate Taxpayer, except as provided in the next sentence. The Corporate Taxpayer and such Member shall bear their own costs and expenses of such proceeding, unless (i) the Expert substantially adopts such Member’s position, in which case the Corporate Taxpayer shall reimburse such Member for any reasonable out-of-pocket costs and expenses in such proceeding, or (ii) the Expert substantially adopts the Corporate Taxpayer’s position, in which case such Member shall reimburse the Corporate Taxpayer for any reasonable out-of-pocket costs and expenses in such proceeding. Any dispute as to whether a dispute is a Reconciliation Dispute within the meaning of this ‎Section 7.09 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this ‎Section 7.09 shall be binding on the Corporate Taxpayer and such Member and may be entered and enforced in any court having jurisdiction.

Section 7.10 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 making of such payment under the Code or any provision of state, local or foreign tax law. 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 Member.

Section 7.11 Admission of the Corporate Taxpayer into a Consolidated Group; Transfers of Corporate Assets.

(a) If the Corporate Taxpayer is or becomes a member of an affiliated or consolidated group of corporations that files a consolidated income tax return pursuant to Sections 1501 et seq. of the Code or any corresponding provisions of state or local law, then: (i) the provisions of this 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 taxable income of the group as a whole.

(b) If any entity that is obligated to make a Tax Benefit Payment or Early Termination Payment hereunder transfers one or more 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, such entity, for purposes of calculating the amount of any Tax Benefit Payment or Early Termination Payment (e.g., calculating the gross income of the entity and determining the Realized Tax Benefit of such entity) due hereunder, shall be treated as having disposed of such asset in a fully taxable transaction on the date of such contribution. The consideration deemed to be received by such entity shall be equal to the fair market value of the contributed asset.

(c) For purposes of this ‎Section 7.11 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.

Section 7.12 Confidentiality. [Section 12.11 (Confidentiality)]³ of the LLC Agreement as of the date of this Agreement shall apply to any information of the Corporate Taxpayer provided to the Members and their assignees pursuant to this Agreement.

Section 7.13 Change in Law. Notwithstanding anything herein to the contrary, if, in connection with an actual or proposed change in law, a Member reasonably believes that the existence of this Agreement could cause income (other than income arising from receipt of a payment under this Agreement) recognized by such Member (or direct or indirect equity holders in such Member) upon an Exchange to be treated as ordinary income rather than capital gain (or otherwise taxed at ordinary income rates) for U.S. federal income tax purposes or would have other material adverse tax consequences to the Corporate Taxpayer or such Member or any direct or indirect owner of a Member, then at the election of such Member and to the extent specified by such Member, this Agreement (i) shall cease to have further effect with respect to such Member, (ii) shall not apply to an Exchange occurring after a date specified by such

³Note to Draft: To be confirmed.

Member, or (iii) shall otherwise be amended in a manner determined by such Member; provided, that such amendment shall not result in an increase in payments under this Agreement to such Member at any time as compared to the amounts and times of payments that would have been due to such Member in the absence of such amendment.

Section 7.14 Partnership Agreement. This Agreement shall be treated as part of the partnership agreement of OpCo 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.
