Section 2.2 Tax Benefit Schedule.

(a) Tax Benefit Schedule. Within ninety (90) calendar days after the filing of the U.S. federal income tax return of the Corporate Taxpayer for any Taxable Year in which the Sale occurs, which is subsequent to the Taxable Year in which the Sale occurs, in which the Reorganizations occur, which is subsequent to the Taxable Year of the Reorganizations, in which any Exchange has been effected by a TRA Party, or which is subsequent to any Taxable Year in which any Exchange has been effected by a TRA Party, the Corporate Taxpayer shall provide to the applicable TRA Party a schedule showing, in reasonable detail, the calculation of the Tax Benefit Payment in respect of such TRA Party for such Taxable Year and the calculation of the Realized Tax Benefit and Realized Tax Detriment and components thereof (a “Tax Benefit Schedule”). Each Tax Benefit Schedule will become final as provided in Section 2.3(a) and may be amended as provided in Section 2.3(b) (subject to the procedures set forth in Section 2.3(b)).

(b) Applicable Principles. For purposes of calculating the Realized Tax Benefit or Realized Tax Detriment for any period, carryovers or carrybacks of any tax item attributable to the Basis Adjustments, Original Basis Adjustment, and Imputed Interest shall be considered to be subject to the rules of the Code and the Treasury Regulations or the appropriate provisions of state, local and non-U.S. tax law, as applicable, governing the use, limitation and expiration of carryovers or carrybacks of the relevant type.

The parties agree that (i) all Tax Benefit Payments and other payments under this Agreement (to the extent permitted by law and 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 2.3 Procedures, Amendments.

(a) Procedure. Every time the Corporate Taxpayer delivers to a DC Capital Party an applicable Schedule under this Agreement, including any Amended Schedule delivered pursuant to Section 2.3(b), and any Early Termination Schedule or amended Early Termination Schedule, the Corporate Taxpayer shall also (x) deliver to such DC Capital Party schedules, valuation reports, if any, and work papers, as determined by the Corporate Taxpayer or requested by such DC Capital Party, providing reasonable detail regarding the preparation of the Schedule and (y) allow such DC Capital Party reasonable access at no cost to the appropriate representatives at the Corporate Taxpayer, as determined by the Corporate Taxpayer or requested by such DC Capital Party, in connection with a review of such Schedule. Without limiting the application of the preceding sentence, each time the Corporate Taxpayer delivers to a DC Capital Party a Tax Benefit Schedule, in addition to the Tax Benefit Schedule duly completed, the Corporate Taxpayer shall deliver to such DC Capital Party the Corporate Taxpayer Return, the reasonably detailed calculation by the Corporate Taxpayer of the applicable Hypothetical Tax Liability, the reasonably detailed calculation by the Corporate Taxpayer of the applicable Actual Tax Liability, as well as any other work papers as determined by the Corporate Taxpayer or requested by such DC Capital Party, 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 all parties thirty (30) calendar days after the first date on which the TRA Party has received the applicable Schedule or amendment thereto unless, in the case of a DC Capital Party, such DC Capital Party (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 Corporate Taxpayer and any objecting DC Capital Party, 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 such DC Capital Party shall employ the reconciliation procedures as described in Section 7.9 of this Agreement (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 after the date the Schedule was provided to a TRA Party, (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 an applicable Exchange 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 TRA Party within ninety (90) calendar days of the occurrence of an event referenced in clauses (i) through (vi) of the preceding sentence.

ARTICLE III

TAX BENEFIT PAYMENTS

Section 3.1 Payments.

(a) Payments. Within five (5) calendar days after a Tax Benefit Schedule delivered to a TRA Party becomes final in accordance with Section 2.3(a) (such date, a “Final Payment Date” in respect of any applicable Tax Benefit Payment), the Corporate Taxpayer shall pay such TRA Party for such Taxable Year an amount equal to the excess, if any, of (i) the Tax Benefit Payment in respect of such TRA Party for such Taxable Year determined pursuant to Section 3.1(b) over (ii) the aggregate amount of Advance Payments previously made to such TRA Party under this Section 3.1(a) in respect of such Taxable Year. In addition, the Corporate Taxpayer may, at its sole election, make Advance Payments to the TRA Parties in respect of a Taxable Year; provided that, if the Corporate Taxpayer makes Advanced Payments, it shall make Advance Payments to all parties eligible to receive payments under this Agreement in proportion to their respective amount of anticipated remaining payments under this Agreement in respect of such Taxable Year. Each such Tax Benefit Payment or such Advance Payment shall be made by wire transfer of immediately available funds to the bank account previously designated by such TRA Party to the Corporate Taxpayer or as otherwise agreed by the Corporate Taxpayer and such TRA Party. For the avoidance of doubt, no Tax Benefit Payment shall be made in respect of estimated tax payments, including, without limitation, federal estimated income tax payments.

(b) A “Tax Benefit Payment” in respect of a TRA Party for a Taxable Year means an amount, not less than zero, equal to the sum of the portion of the Net Tax Benefit Attributable to such TRA Party and the Interest Amount with respect thereto. A Net Tax Benefit is “Attributable” to a TRA Party to the extent that is derived from any Basis Adjustment, the Original Basis Adjustment, and any Imputed Interest that is attributable to the Common Units acquired by Corporate Taxpayer in the Sale, the Reorganizations or an Exchange, as applicable, undertaken by or with respect to such TRA Party. 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 the Sale or Exchanges, as applicable, unless otherwise required by law. 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 sum of the total amount of payments previously made under Section 3.1(a) of this Agreement (excluding payments attributable to Interest Amounts); provided, for the avoidance of doubt, that no TRA Party shall be required to return any portion of any previously made Tax Benefit Payment or Advance Payment. The “Interest Amount” in respect of a TRA Party shall equal the interest on the amount of the unpaid Net Tax Benefit Attributable to such TRA Party for a Taxable Year, which interest shall accrue on any unpaid Net Tax Benefit from and after the due date (without extensions) for filing the Corporate Taxpayer Return for such Taxable Year, calculated at the Agreed Rate, until the date such unpaid amounts are paid. “Advance Payments” in respect of a TRA Party for a Taxable Year means the payments made by the Corporate Taxpayer to such TRA Party as an advance of such TRA Party’s anticipated Tax Benefit Payment for such Taxable Year.

(c) In the event that the Corporate Taxpayer does not make timely payment of all or any portion of a Tax Benefit Payment to a TRA Party on or before a date on which a Tax Benefit Payment is due as determined pursuant to Section 3.1(a), the amount of “Default Rate Interest” calculated in respect of the Net Tax Benefit (including previously accrued Imputed Interest and Extension Rate Interest) for a Taxable Year will equal interest calculated at the Default Rate from a Final Payment Date for a Tax Benefit Payment as determined pursuant to Section 3.1(a) until the date on which the Corporate Taxpayer makes such Tax Benefit Payment to such TRA Party. For the avoidance of doubt, the amount of any Default Rate Interest as determined with respect to any Net Tax Benefit payable by the Corporate Taxpayer to a TRA Party shall be excluded in the Hypothetical Tax Liability of the Corporate Taxpayer for purposes of calculating Realized Tax Benefits and Realized Tax Detriments pursuant to this Agreement.

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

Section 3.3 Pro Rata Payments; Coordination of Benefits.

(a) Notwithstanding anything in Section 3.1 to the contrary, to the extent that the aggregate amount of the Corporate Taxpayer’s tax benefit from the reduction in Covered Tax liability as a result of the Basis Adjustments, Original Basis Adjustment, or 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 TRA Parties 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.

(b) After taking into account Section 3.3(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 TRA Parties agree that (i) the Corporate Taxpayer shall pay the same proportion of each Tax Benefit Payment due to each Person due a payment 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) If for any reason the Corporate Taxpayer is not able to timely and fully satisfy its payment obligations under this Agreement in respect of a particular Taxable Year, then Default Rate Interest will begin to accrue pursuant to Section 5.2.

(d) To the extent the Corporate Taxpayer makes a payment to a TRA Party in respect of a particular Taxable Year under Section 3.1(a) of this Agreement (taking into account Section 3.3(a) and (b), but excluding payments attributable to Interest Amounts) in an amount in excess of the amount of such payment that should have been made to such TRA Party in respect of such Taxable Year, then (i) such TRA Party shall not receive further payments under Section 3.1(a) until such TRA Party has foregone an amount of payments equal to such excess and (ii) the Corporate Taxpayer shall pay the amount of such TRA Party’s foregone payments to the other TRA Parties under this Agreement in a manner such that each of the other TRA Parties, to the maximum extent possible, shall have received aggregate payments under Section 3.1(a) of this Agreement (taking into account Section 3.3(a) and (b) of this Agreement, but excluding payments attributable to Interest Amounts) in the amount it would have received if there had been no excess payment to such TRA Party.

ARTICLE IV

TERMINATION

Section 4.1 Early Termination and Breach of Agreement.

(a) The Corporate Taxpayer may terminate this Agreement with respect to all amounts payable to the TRA Parties and with respect to all of the Common Units held by the TRA Parties at any time by paying (i) to each TRA Party the Early Termination Payment in respect of such TRA Party; provided, however, that if the Corporate Taxpayer and the DC Capital Representative agree, the

Corporate Taxpayer may terminate this Agreement with respect to some or all of the amounts payable to less than all of the TRA Parties under this Agreement; provided, further that this Agreement shall only terminate pursuant to this Section 4.1(a) with respect to a TRA Party upon the receipt of the Early Termination Payment by such TRA Party, and the Corporate Taxpayer shall deliver an Early Termination Notice only if it is able to make all required Early Termination Payments under this Agreement at the time required by Section 4.3, and provided, further, that the Corporate Taxpayer may withdraw any notice to execute its termination rights under this Section 4.1(a) 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 4.1(a) and Section 4.3, the Corporate Taxpayer shall not have any further payment obligations under this Agreement with respect to the TRA Parties that have received their Early Termination Payment in accordance with this Section 4.1(a) and Section 4.3, other than for any (a) Tax Benefit Payment agreed to by the Corporate Taxpayer, on one hand, and the applicable TRA Party, on the other, as due and payable but unpaid as of the Early Termination Notice and (b) 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 (b) is included in the Early Termination Payment). If an Exchange by a TRA Party occurs after the Corporate Taxpayer makes the Early Termination Payment to such TRA Party pursuant to this Section 4.1(a), the Corporate Taxpayer shall have no obligations under this Agreement with respect to such Exchange.

(b) 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 to the extent not cured within thirty (30) days of receiving written notice from any TRA Party that is materially prejudiced by such failure 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 (without duplication), but not be limited to, (1) the Early Termination Payments calculated as if an Early Termination Notice had been delivered on the date of a breach, (2) any Tax Benefit Payment in respect of a TRA Party agreed to by the Corporate Taxpayer and such TRA Party as due and payable but unpaid as of the date of a breach, and (3) any Tax Benefit Payment in respect of any TRA Party due for the Taxable Year ending with or including the date of a breach; provided, that procedures similar to the procedures of Section 4.2 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 TRA Party shall be entitled to elect to receive the amounts set forth in clauses (1), (2) and (3) 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 Tax Benefit Payment when due to the extent that 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 the Company or any other Subsidiaries to distribute or lend funds for such payment and access any revolving credit facilities or other sources of available credit to fund any such amounts); provided that the interest provisions of Section 5.2 shall apply to such late payment; and provided, further that, solely with respect to a Tax Benefit Payment, if the Corporate Taxpayer does not have sufficient cash to make such payment as a result of limitations imposed by existing credit agreements to which the Company is a party, which limitations are effective as of the date of this Agreement, Section 5.2 shall apply, but the Default Rate shall be replaced by the Agreed Rate.

(c) In the event of a Change of Control, all obligations hereunder shall be accelerated and such obligations shall be calculated pursuant to this Article IV as if an Early Termination Notice had been delivered on the closing date of the Change of Control and utilizing the Valuation Assumptions by substituting the phrase “the closing date of a Change of Control” in each place where the phrase “Early Termination Effective Date” appears. Such obligations shall include, but not be limited to, (1) the Early Termination Payment calculated as if an Early Termination Notice had been delivered on the closing date of the Change of Control, (2) any Tax Benefit Payments agreed to by the Corporate Taxpayer and the Beneficiaries or Blocker Owners as due and payable but unpaid as of the Early Termination Notice and (3) any Tax Benefit Payments due for any Taxable Year ending prior to, with or including the closing date of a Change of Control (except to the extent that any amounts described in clauses (2) or (3) are included in the Early Termination Payment). For the avoidance of doubt, Sections 4.2 and 4.3 shall apply to a Change of Control, mutadis mutandi.

Section 4.2 Early Termination Notice. If the Corporate Taxpayer chooses to exercise its right of early termination under Section 4.1 above, the Corporate Taxpayer shall deliver to each TRA Party 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(s) due for each TRA Party. Each Early Termination Schedule shall become final and binding on all parties thirty (30) calendar days after the first date on which the TRA Party has received such Schedule or amendment thereto unless, in the case of a DC Capital Party, such DC Capital Party (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 the DC Capital Party, 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 the objecting DC Capital Party shall employ the Reconciliation Procedures in which case such Schedule becomes binding ten (10)  days after the conclusion of the Reconciliation Procedures.

Section 4.3 Payment upon Early Termination.

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

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

ARTICLE V

SUBORDINATION AND LATE PAYMENTS

Section 5.1 Subordination. Notwithstanding any other provision of this Agreement to the contrary, any Tax Benefit Payment, Early Termination Payment or any other payment required to be

made by the Corporate Taxpayer to the TRA Parties 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 (such obligations, “Senior Obligations”) and shall rank pari passu with all current or future unsecured obligations of the Corporate Taxpayer that are not Senior Obligations. For the avoidance of doubt, any amounts owed by the Corporate Taxpayer under this Agreement are not Senior Obligations.

Section 5.2 Late Payments by the Corporate Taxpayer. The amount of all or any portion of any Tax Benefit Payment, Early Termination Payment or other payment under this Agreement not made to the TRA Parties 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, Early Termination Payment or other payment was due and payable.

ARTICLE VI

Section 6.4 Tax Treatment of TRA Party Rights. The Parties acknowledge and hereby agree to treat for all tax reporting purposes any payments made to a TRA Party (other than the Blocker Owners) under this Agreement: (i) such payments arising from the Sale or an Exchange, as money received within

the meaning of Section 1001(b) of the Code for the applicable Common Units exchanged by such TRA Party in the Sale or such Exchange, in each case, except with respect to Imputed Interest. The Parties shall for all tax reporting purposes treat such payments consistently with this Section 6.4 except upon a contrary final determination by an applicable Taxing Authority.

Section 6.5 Tax Treatment of Blocker Owners Rights. The Parties acknowledge and hereby agree to treat for U.S. federal income tax purposes any payments made to a Blocker Owner under this Agreement as additional consideration described as “other property” within the meaning of Section 356 of the Code pursuant to the applicable transaction in the Reorganizations, except with respect to Imputed Interest. The Parties shall for all tax reporting purposes treat such payments consistently with this Section 6.5 except upon a contrary final determination by an applicable taxing authority.

Section 7.7 Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience of reference only and are not to be considered in construing this Agreement.

Section 7.8 Resolution of Disputes.

(a) Any and all disputes which are not governed by Section 7.9 and cannot be settled amicably, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or nonperformance of this Agreement (including the validity, scope and enforceability of this arbitration provision) (each a “Dispute”) shall be finally settled by arbitration conducted by a single arbitrator in New York in accordance with the then-existing Rules of Arbitration of the International Chamber of Commerce. If the parties to the Dispute fail to agree on the selection of an arbitrator within ten (10) calendar 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 New York and shall conduct the proceedings in the English language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

(b) Notwithstanding the provisions of paragraph (a), the Corporate Taxpayer may bring an action or special proceeding in any court of competent jurisdiction for the purpose of compelling a party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing an arbitration award and, for the purposes of this paragraph (b), the TRA Party (i) expressly consents to the application of paragraph (c) of this Section 7.8 to any such action or proceeding, (ii) agrees that proof shall not be required that monetary damages for breach of the provisions of this Agreement would be difficult to calculate and that remedies at law would be inadequate, and (iii) irrevocably appoints the Corporate Taxpayer as agent of the TRA Party 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 TRA Party of any such service of process, shall be deemed in every respect effective service of process upon the TRA Party in any such action or proceeding.

BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF THIS SECTION 7.8, OR ANY JUDICIAL PROCEEDING ANCILLARY TO AN ARBITRATION OR CONTEMPLATED ARBITRATION ARISING OUT OF OR RELATING TO OR CONCERNING THIS AGREEMENT. Such ancillary judicial proceedings include any suit, action or proceeding to compel arbitration, to obtain temporary or preliminary judicial relief in aid of arbitration, or to confirm an arbitration award. The parties acknowledge that the for a designated by this paragraph (c) have a reasonable relation to this Agreement, and to the parties’ relationship with one another; and

(ii) 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 7.8 and such parties agree not to plead or claim the same.

Section 7.9 Reconciliation. In the event that the Corporate Taxpayer and a DC Capital Party are unable to resolve a disagreement with respect to the matters governed by Sections 2.3, 3.1, 4.2 or 6.2 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 the DC Capital Party agree otherwise, the Expert shall not, and the firm that employs the Expert shall not, have any material relationship with the Corporate Taxpayer or the DC Capital Party or other actual or potential conflict of interest. If the Corporate Taxpayer and the DC Capital Party 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 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 the DC Capital Party shall bear their own costs and expenses of such proceeding, unless (i) the Expert adopts the DC Capital Party’s position, in which case the Corporate Taxpayer shall reimburse the DC Capital Party for any reasonable out-of-pocket costs and expenses in such proceeding, or (ii) the Expert adopts the Corporate Taxpayer’s position, in which case the DC Capital Party 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 7.9 shall be decided by the Expert. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this Section 7.9 shall be binding on the Corporate Taxpayer and the DC Capital Party 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 Person in respect of whom such withholding was made.

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 United States 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 gross fair market value of the contributed asset. 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 allocated to such partner.

Section 7.12 Confidentiality.

(a) Each TRA Party and each of their assignees 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 and its Affiliates, as required by law or legal process or to enforce the terms of this Agreement, such person shall keep and retain in the strictest confidence and not disclose to any Person any confidential matters, acquired pursuant to this Agreement, of the Corporate Taxpayer and its Affiliates and successors, concerning the Company and its Affiliates and successors or the TRA Parties, learned by the TRA Party heretofore or hereafter. This Section 7.12 shall not apply to (i) any information that has been made publicly available by the Corporate Taxpayer or any of its Affiliates, becomes public knowledge (except as a result of an act of the TRA Party in violation of this Agreement) or is generally known to the business community and (ii) the disclosure of information to the extent necessary for the TRA Party 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 returns. Notwithstanding anything to the contrary herein, each TRA Party and each of their assignees (and each employee, representative or other agent of the TRA Party or its assignees, as applicable) may disclose to any and all Persons, without limitation of any kind, the tax treatment and tax structure of the Corporate Taxpayer, the Company and their Affiliates, and any of their transactions, and all materials of any kind (including opinions or other tax analyses) that are provided to the TRA Party relating to such tax treatment and tax structure.

(b) If a TRA Party or an assignee commits a breach, or threatens to commit a breach, of any of the provisions of this Section 7.12, the Corporate Taxpayer shall have the right and remedy to have the provisions of this Section 7.12 specifically enforced by injunctive relief or otherwise by any court of competent jurisdiction without the need to post any bond or other security, it being acknowledged and agreed that any such breach or threatened breach shall cause irreparable injury to the Corporate Taxpayer or any of its Subsidiaries or the TRA Parties and the accounts and funds managed by the Corporate Taxpayer and that money damages alone shall not provide an adequate remedy to such Persons. Such rights and remedies shall be in addition to, and not in lieu of, any other rights and remedies available at law or in equity.

Section 7.13 LLC Agreement. This Agreement shall be treated as part of the partnership agreement of the Company 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.
