ARTICLE II.

DETERMINATION OF CUMULATIVE REALIZED TAX BENEFIT

2.1 Applicable Calculation Principles. Subject to Section 3.3(a), Section 4.1(c) and Section 4.3, the Realized Tax Benefit or Realized Tax Detriment is intended to measure the decrease or increase in the actual liability for Taxes of, without duplication, each Consolidated Group and the Corporation (and Holdings, but only with respect to Taxes imposed on Holdings and allocable to the Consolidated Group or the Corporation) for a Taxable Year attributable to Basis Adjustments, Imputed Interest and Interest Amounts, as applicable, determined using a “with and without” methodology. For the avoidance of doubt, the actual liability for Taxes 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 Corporation for the Units acquired in an Exchange. Carryovers or carrybacks of any Tax item attributable to Basis Adjustments, Imputed Interest and Interest Amounts, as applicable, 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 Adjustments, Imputed Interest or Interest Amounts, as applicable, 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) any Tax Benefit Payment exceeding $100 in respect of an Exchanging Partner in an Exchange attributable to the Basis Adjustments in respect of such Exchanging Partner (other than amounts accounted for as interest under the Code) will (A) be treated as a subsequent upward purchase price adjustment and (B) have the effect of creating additional Basis Adjustments in respect of such Exchanging Partner to Exchange Reference Assets in the year of payment, and (ii) as a result, such additional Basis Adjustments in respect of such Exchanging Partner will be incorporated into the current year calculation and into future year calculations, as appropriate.

2.2 Exchange Basis Schedule. Within 120 days after the filing of the U.S. federal income Tax Return of the Corporation or any Consolidated Group for each Taxable Year in which an Exchange has been effected, the Corporation shall deliver to each Exchanging Partner a schedule (an “Exchange Basis Schedule”) that shows, in reasonable detail necessary to perform the calculations required by this Agreement, for purposes of Taxes, (i) the Non-Stepped Up Tax Basis of the Exchange Reference Assets attributable to such Exchanging Partner as of each applicable Exchange Date, (ii) the Basis Adjustment attributable to such Exchanging Partner with respect to the Exchange Reference Assets as a result of the Exchanges effected in such Taxable Year by such Exchanging Partner, calculated in the aggregate, (iii) the period or periods, if any, over which the Exchange Reference Assets are estimated to be depletable, amortizable and/or depreciable, and (iv) the period or periods, if any, over which each Basis Adjustment attributable to such Exchanging Partner is estimated to be depletable, amortizable and/or depreciable (which, for non-amortizable assets shall be based on the Valuation Assumptions).

2.3 Tax Benefit Schedule. Within 120 days after the filing of the U.S. federal income Tax Return of the Corporation, any Consolidated Group for any Taxable Year in which there is a Realized Tax Benefit or Realized Tax Detriment, the Corporation shall provide to each Exchanging Partner a schedule showing, in reasonable detail, the calculation of the Realized Tax Benefit or Realized Tax Detriment attributable to such Exchanging Partner for such Taxable Year (a “Tax Benefit Schedule”). The 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)).

2.4 Procedures, Amendments.

(a) Procedure. Every time the Corporation delivers to an Exchanging Partner an applicable Schedule under this Agreement, including any Amended Schedule delivered pursuant to Section 2.4(b), but excluding any Early Termination Schedule or amended Early Termination Schedule, the Corporation shall also deliver to the Exchanging Partner schedules and work papers, as determined by the Corporation or reasonably requested by the Exchanging Partner, providing reasonable detail regarding the preparation of the Schedule. Without limiting the application of the preceding sentence, each time the Corporation delivers to an Exchanging Partner a Tax Benefit Schedule, in addition to the Tax Benefit Schedule, the Corporation shall deliver to such Exchanging Partner a reasonably detailed calculation by the Corporation of the applicable Hypothetical Tax Liability in respect of such Exchanging Partner, a reasonably detailed calculation by the Corporation of the actual Tax liability (determined as specified in Section 2.1), as well as any other work papers as determined by the Corporation or reasonably requested by such Exchanging Partner. The applicable Schedule shall become final and binding on all parties unless the Exchanging Partner, within 30 calendar days after receiving an Exchange Basis Schedule or amendment thereto or a Tax Benefit Schedule or amendment thereto, provides the Corporation with notice of a material objection to such Schedule (“Objection Notice”) made in good faith. If the parties, for any reason, are unable to successfully resolve the issues raised in such notice within 30 calendar days of receipt by the Corporation of an Objection Notice, if with respect to an Exchange Basis Schedule or a Tax Benefit Schedule, the Corporation and the Exchanging Partner shall employ the reconciliation procedures as described in Section 7.9 of this Agreement (the “Reconciliation Procedures”).

(b) Amended Schedule. The applicable Schedule in respect of an Exchanging Partner for any Taxable Year may be amended from time to time by the Corporation (i) in connection with a Determination affecting such Schedule, (ii) to correct material 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 Exchanging Partner, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, (iv) to reflect a material change in the Realized Tax Benefit or Realized Tax Detriment in respect of the Exchanging Partner 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 material change in the Realized Tax Benefit or Realized Tax Detriment in respect of the Exchanging Partner 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 (such Schedule, an “Amended Schedule”). The Corporation shall provide any Amended Schedule to the Exchanging Partner, within 30 calendar days of the notice of occurrence of an event referred to in clauses (i) through (vi) of the preceding sentence, and any such Amended Schedule shall be subject to approval procedures similar to those described in Section 2.4(a).

ARTICLE III.

TAX BENEFIT PAYMENTS

3.1 Payments.

(a) Payments. Subject to the last sentence of Section 4.1(b), within thirty (30) calendar days of a Tax Benefit Schedule that was delivered to an Exchanging Partner becoming final in accordance with Section 2.4(a), the Corporation shall pay to such Exchanging Partner, for such Taxable Year, the Tax Benefit Payment with respect to such Exchange determined pursuant to Section 3.1(b). Each such Tax Benefit Payment shall be made by wire transfer (or as otherwise

directed by the Exchanging Partner) of immediately available funds to a bank account of the Exchanging Partner previously designated by such Exchanging Partner to the Corporation. For the avoidance of doubt, no Tax Benefit Payment shall be made in respect of estimated Tax payments, including, without limitation, U.S. federal estimated income Tax payments.

(b) A “Tax Benefit Payment” means an amount, not less than zero, equal to the sum of the Net Tax Benefit and the 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 Units in Exchanges unless otherwise required by law. The “Net Tax Benefit” for each Taxable Year shall be an amount equal to the excess, if any, of 85% of the Cumulative Net Realized Tax Benefit over the total amount of payments previously made under this Section 3.1, excluding payments attributable to the Interest Amount; provided, however, that for the avoidance of doubt, no Exchanging Partner shall be required to return any portion of any previously made Tax Benefit Payment. The “Interest Amount” for a given Taxable Year shall equal the interest on the Net Tax Benefit for such Taxable Year calculated at the Agreed Rate from the due date (without extensions) for filing the Corporation Return with respect to Taxes for the most recently ended Taxable Year until the Payment Date. The Net Tax Benefit and the Interest Amount shall be determined separately with respect to each separate Exchange, by reference to the resulting Basis Adjustment to the Corporation.

(c) The Corporation shall use good faith efforts to ensure that it has sufficient Available Cash to make all payments due under this Agreement without regard to the last sentence of Section 4.1(b).

(d) Notwithstanding any provision of this Agreement to the contrary, an Exchanging Partner may elect for the provisions of this Section 3.1(d) to apply to any Exchange by notifying the Corporation in writing on or before the due date for providing the Exchange Notice with respect to such Exchange. Following such election, the aggregate Tax Benefit Payments to be made to such Exchanging Partner with respect to any Exchange shall be limited to (i) 100% or such lower percentage such Exchanging Partner elects to apply by notifying the Corporation in writing on or before the due date for providing the Exchange Notice with respect to such Exchange, of (ii) the amount equal to the sum of (A) any cash, excluding any Tax Benefit Payments, received by such Exchanging Partner in such Exchange and (B) the aggregate Market Value of the Class A Shares received by such Exchanging Partner in such Exchange, provided, for the avoidance of doubt, that such amount shall not include any Imputed Interest with respect to such Exchange.

3.2 No Duplicative Payments. Notwithstanding anything in this Agreement to the contrary, 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 Corporation’s Cumulative Net Realized Tax Benefit, and the Interest Amount thereon, being paid to the Limited Partners pursuant to this Agreement. The provisions of this Agreement shall be construed in the appropriate manner so that these fundamental results are achieved.

3.3 Pro Rata Payments; Coordination of Benefits.

(a) Notwithstanding anything in Section 3.1 to the contrary, to the extent that the aggregate Tax benefit of the Corporation or any Consolidated Group’s deduction with respect to the Basis Adjustments, Imputed Interest or Interest Amounts in respect of all Exchanging Limited Partners under this Agreement is limited in a particular Taxable Year because the Corporation or applicable Consolidated Group does not have sufficient Taxable income, the limitation on the Tax

benefit for the Corporation or the applicable Consolidated Group shall be allocated among the Exchanging Limited Partners in proportion to the respective amounts of Realized Tax Benefits that would have been determined under this Agreement in respect of each Exchanging Partner if the Corporation or applicable Consolidated Group had sufficient Taxable income so that there were no such limitation.

(b) If for any reason the Corporation 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 Corporation and the Exchanging Limited Partners agree that (i) the Corporation 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 another, 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.

ARTICLE IV.

TERMINATION

4.1 Early Termination and Breach of Agreement.

(a) The Corporation may terminate this Agreement at any time by paying to each Limited Partner the Early Termination Payment attributable to each such Limited Partner; provided, however, that this Agreement shall only terminate upon the receipt of the Early Termination Payment by all Limited Partners, and provided, further, that the Corporation 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 Payments by the Corporation, neither the Limited Partners nor the Corporation shall have any further payment obligations under this Agreement, other than for any (a) Tax Benefit Payment agreed to by the Corporation and an Exchanging Partner as due and payable but unpaid as of the Early Termination Notice and (b) Tax Benefit Payment in respect of an Exchanging Partner 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). For the avoidance of doubt, if an Exchange occurs after the Corporation makes the Early Termination Payments with respect to all Limited Partners, the Corporation shall have no obligations under this Agreement with respect to such Exchange, and its only obligations under this Agreement in such case shall be its obligations to all Limited Partners under Section 4.3(a).

(b) In the event that the Corporation 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 to each Limited Partner on the date of such breach and shall include, but shall not be limited to, (1) the Early Termination Payment of such Limited Partner calculated as if an Early Termination Notice had been delivered on the date of a breach, (2) any Tax Benefit Payment in respect of such Limited Partner agreed to by the Corporation and such Limited Partner as due and payable but unpaid as of the date of a breach, and (3) any Tax Benefit Payment in respect of such Limited Partner due for the Taxable Year ending with or including the date of a breach. Notwithstanding the foregoing, in the event that the Corporation breaches this Agreement, the Limited Partners 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 six

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 six 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 Corporation fails to make any Tax Benefit Payment (other than an Early Termination) when due to the extent that the Corporation has insufficient Available Cash to make such payment; provided, however, that the interest provisions of Section 5.2 shall apply to such late payment (unless the Corporation does not have Available Cash to make such payment as a result of limitations imposed by existing credit agreements to which Holdings is a party, in which case Section 5.2 shall apply, but the Default Rate shall be replaced by the Agreed Rate).

4.2 Early Termination Notice. If the Corporation chooses to exercise its right of early termination under Section 4.1 above, the Corporation shall deliver to each Limited Partner notice of such intention to exercise such right (“Early Termination Notice”) and a schedule (the “Early Termination Schedule”) specifying the Corporation’s intention to exercise such right and showing in reasonable detail the calculation of the Early Termination Payment for that Limited Partner. The Early Termination Schedule shall become final and binding on a Limited Partner (and on the Corporation as to that Limited Partner) unless the Limited Partner, within 30 calendar days after receiving the Early Termination Schedule, provides the Corporation with notice of a material objection to such Schedule made in good faith (“Material Objection Notice”). If the parties, for any reason, are unable to successfully resolve the issues raised in such notice within 30 calendar days after receipt by the Corporation of the Material Objection Notice, the Corporation and the Limited Partner shall employ the Reconciliation Procedures as described in Section 7.9 of this Agreement. All Early Termination Schedules affected by any changes resulting from a Material Objection Notice shall be updated and the Early Termination Payment(s) due in respect thereof shall be recalculated by the Corporation to take into account such changes.

4.3 Payment upon Early Termination.

(a) Within thirty (30) days calendar days after agreement between a Limited Partner and the Corporation of the Early Termination Schedule or the Expert’s determination under the Reconciliation Procedures, as applicable, the Corporation shall pay to such Limited Partner an amount equal to the Early Termination Payment determined for such Limited Partner. Such payment shall be made by wire transfer (or as otherwise directed by the Limited Partner) of immediately available funds to a bank account designated by the Limited Partner.

(b) The “Early Termination Payment” as of the date of the delivery of an Early Termination Schedule shall equal with respect to any Limited Partner the sum of (i) the present value, discounted at the Early Termination Rate as of such date, of all Tax Benefit Payments that would be required to be paid by the Corporation to the Limited Partner (which in the case of a Limited Partner that has Units that have not previously been Exchanged shall be calculated as if such Limited Partner made an Exchange of all its remaining Units on the Early Termination Date) and assuming that the Valuation Assumptions are applied and (ii) without duplication of any amounts referred to in (i), amounts deferred pursuant to the last sentence of Section 4.1(b) (including interest).

ARTICLE V.

SUBORDINATION AND LATE PAYMENTS

5.1 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 Corporation to the Limited Partners under this Agreement (an “Exchange Payment”) 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 Corporation or any of its Subsidiaries (“Senior Obligations”) and shall rank pari passu with all current or future unsecured obligations of the Corporation that are not Senior Obligations.

5.2 Late Payments by the Corporation. The amount of all or any portion of any Exchange Payment not made to any Exchanging Partner when due under the terms of this Agreement shall be payable together with any interest thereon, computed at the Default Rate (rather than the Agreed Rate) and commencing from the date on which such Exchange Payment was due and payable.

ARTICLE VI.

NO DISPUTES; CONSISTENCY; COOPERATION

6.1 Initial Limited Partner Participation in the Corporation’s and Holdings’ Tax Matters. Except as otherwise provided herein, the Corporation shall have full responsibility for, and sole discretion over, all Tax matters concerning the Corporation, and Consolidated Group and Holdings, including without limitation the preparation, filing or amending of any Tax Return and defending, contesting or settling any issue pertaining to Taxes. Notwithstanding the foregoing, the Corporation shall notify each Initial Limited Partner of, and keep such Initial Limited Partner reasonably informed with respect to, the portion of any audit of the Corporation, and Consolidated Group and Holdings by a Taxing Authority the outcome of which is reasonably expected to affect such Initial Limited Partner’s rights and obligations under this Agreement, and shall provide to such Initial Limited Partner reasonable opportunity to provide information and other input to the Corporation, Holdings and their respective advisors concerning the conduct of any such portion of such audit; provided, however, that the Corporation and Holdings shall not be required to take any action that is inconsistent with any provision of the Partnership Agreement.

6.2 Consistency. Except for items that are explicitly described as “deemed” or in similar manner by the terms of this Agreement, the Corporation and each Limited Partner 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 without limitation the Basis Adjustment and each Tax Benefit Payment) in a manner consistent with that specified by the Corporation in any Schedule required to be provided by or on behalf of the Corporation under this Agreement.

6.3 Cooperation. Each Limited Partner shall (a) furnish to the Corporation in a timely manner such information, documents and other materials as the Corporation 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 Corporation and its representatives to provide explanations of documents and materials and such other information as the Corporation 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 Corporation shall reimburse the Limited Partner for any reasonable third-party costs and expenses incurred pursuant to this Section.

7.3 Entire Agreement; No Third Party Beneficiaries. This Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof. This Agreement shall be binding upon and inure solely to the benefit of each party hereto and their respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

7.4 Governing Law. This Agreement shall be governed by, and construed in accordance with, the law of the State of Texas, without regard to the conflicts of laws principles thereof that would mandate the application of the laws of another jurisdiction.

7.5 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect 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 determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

7.6 Successors; Assignment; Amendments; Waivers. No Limited Partner may assign this Agreement to any person without the prior written consent of the Corporation; provided, however, that (i) to the extent Units are effectively transferred in accordance with the terms of the Partnership Agreement, the transferring Limited Partner shall have the option to assign to the transferee of such Units the transferring Limited Partner’s rights under this Agreement with respect to such transferred Units, as long as such transferee has executed and delivered, or, in connection with such transfer, executes and delivers, a Joinder Agreement in the form attached hereto as Exhibit A, agreeing to become a “Limited Partner” for all purposes of this Agreement, except as otherwise provided in such Joinder Agreement, and (ii) any and all payments payable to a Limited Partner pursuant to this Agreement with respect to a Limited Partner may be assigned to any Person or Persons, including a liquidating trust, as long as any such Person has executed and delivered, or, in connection with such assignment, executes and delivers, a Joinder Agreement in the form attached hereto as Exhibit A, agreeing to be bound by Section 7.13 and acknowledging specifically the terms of the next paragraph. For the avoidance of doubt, if a Person transfers Units (regardless of whether the transferee is a “Permitted Transferee” under the terms of the Partnership Agreement) but does not assign to the transferee of such Units such Person’s rights, if any, under this Agreement with respect to such transferred Units or payments payable to such Limited Partner under this Agreement, such Person shall be entitled to receive the Tax Benefit Payments, if any, due hereunder including with respect to, any Tax Benefit Payments arising in respect of a subsequent Exchange of, such Units.

Notwithstanding the foregoing provisions of this Section 7.6, and other than a transferee or assignee who is a beneficial owner of an interest in HMH or Riverstone, (a) no transferee described in clause (i) of the immediately preceding paragraph shall have the right to enforce the provisions of Sections 2.4, 4.2, 6.1 or 6.2 of this Agreement, and (b) no assignee described in clause (ii) of the immediately preceding paragraph shall have any rights under this Agreement except for the right to enforce its right to receive payments under this Agreement.

No provision of this Agreement may be amended unless such amendment is approved in writing by each of the Corporation and Holdings and each Initial Limited Partner. 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.

All of the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the parties hereto and their respective successors, assigns, heirs, executors, administrators and legal representatives. The Corporation 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 Corporation, by written agreement, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be required to perform if no such succession had taken place. For the avoidance of doubt and notwithstanding anything to the contrary herein, in the event an Initial Limited Partner transfers Units to a Permitted Transferee (as defined in the Partnership Agreement) that is a beneficial owner of interest in such Initial Limited Partner, then such beneficial owner shall have the right to enforce the provisions of Sections 2.4, 4.2 or 6.1 with respect to such transferred Units.

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.

7.8 Resolution of Disputes.

(a) Any and all disputes, including but not limited to 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) (each a “Dispute”) shall be finally settled by arbitration conducted by a single arbitrator in Xxxxxx County, Texas in accordance with this Section 7.8, regardless of whether some or all of any Dispute allegedly (i) is extra-contractual in nature, (ii) sounds in contract, tort or otherwise, (iii) is provided by U.S. federal or state statute, common law or otherwise, or (iv) seeks damages or any other relief, whether at law, in equity or otherwise.

(b) 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, either party may apply to the U.S. District Court of the Southern District of Texas, Houston Division, or any other court of competent jurisdiction, for the appointment of an arbitrator pursuant to the Federal Arbitration Act, 9 U.S.C. § 5.

(c) Notwithstanding the fact that any matter in dispute between the parties is to be submitted, or has already been submitted, to arbitration, the parties shall continue to observe and perform their respective obligations and duties under this Agreement during any arbitration proceedings.

(d) Subject to any relevant legal privilege, within 30 days of the selection of an arbitrator, each party shall be required to disclose to the other party all documents that are relevant to the Dispute and to identify all persons likely to have knowledge of facts relevant to the dispute. Absent a showing of undue prejudice and necessity, there shall be no other discovery, whether by requests for production, interrogatories or deposition, in connection with the arbitration. The arbitrator shall have the power to make all orders necessary for the disclosure contemplated herein, which orders the parties consent in advance to obey. If a party fails or refuses to comply with an order for disclosure, the arbitrator may take that failure into account when deciding the issues and may infer that the documents not produced would have supported the opposing party’s claims.

(e) The presentation of evidence shall be limited to: (1) no more than two pre-hearing written submissions by each party, which shall include witness statements, declarations, or affidavits, expert reports, and all documentary and tangible evidence, and legal authority upon which the party relies, and (2) cross-examination at the hearing of only persons submitting statements, declarations, affidavits, or expert reports.

(f) Barring extraordinary circumstances as may be determined by the arbitrator, the arbitration proceedings will be concluded within 120 days from the selection of the arbitrator, which time may be extended in the interest of justice and failure to adhere to or meet this limit shall not constitute a basis for challenging the award. The parties to a Dispute may by mutual written agreement, and with the consent of the arbitrator, extend any of the deadlines of this Section 7.8.

(g) In addition to monetary damages, the arbitrator shall be empowered to issue procedural orders or interim measures upon application of any party, including requests for injunctive relief, specific performance of any obligation under this Agreement, and other equitable remedies, which may be enforced as necessary in any court of competent jurisdiction. The arbitrator shall not decide a Dispute ex aqueo et xxxx or as amiable compositeur, and is not empowered to award damages in excess of compensatory damages, and each party hereby

irrevocably waives any right to recover punitive, exemplary or similar damages with respect to any Dispute. The arbitrator shall not have the authority to modify or amend any term or provision of this Agreement. The award shall be final and binding upon the parties as from the date rendered, and shall be the sole and exclusive remedy between the parties regarding any claims, counterclaims, issues, or accounting presented to the arbitral tribunal. Judgment upon any award may be entered and enforced in any court having jurisdiction over a party or any of its assets.

(h) The award shall include interest, unless the arbitrator determines it is not appropriate. Interest shall run from the date of any breach or violation of the Agreement, which shall be determined by the arbitrator in its award. If the arbitrator cannot determine such date or fails to specify such date in its award, interest shall run from the date of serving the request for arbitration. Interest shall continue to run from the date of award until the award is paid in full. Interest shall be calculated and compounded monthly at the one-year US$ LIBOR rate as published by the Financial Times on the first business day of the applicable month plus 4 per cent.

(i) The arbitrator shall designate a prevailing party (or parties) in its final award and, pursuant to this determination, shall award to the prevailing party (or parties) its attorneys’ fees, costs and expenses of the arbitration (including the arbitrators’ fees and expenses) in full.

(j) Notwithstanding the provisions of paragraph (a), the Corporation 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 (j), each Limited Partner (1) expressly consents to the application of paragraph (i) of this Section 7.8 to any such action or proceeding, (2) 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 (3) irrevocably appoints the Corporation as such Limited Partner’s 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 such Limited Partner of any such service of process, shall be deemed in every respect effective service of process upon the Limited Partner in any such action or proceeding.

(k) EACH PARTY HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF COURTS LOCATED IN AUSTIN, TEXAS FOR THE PURPOSE OF ANY JUDICIAL 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 forum designated by this paragraph (b) have a reasonable relation to this Agreement, and to the parties’ relationship with one another; and 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 this Section 7.8 and such parties agree not to plead or claim the same.

7.9 Reconciliation. In the event that the Corporation and the Limited Partner are unable to resolve a disagreement with respect to the matters governed by Sections 2.4, 4.2 and 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 in a nationally recognized accounting firm or a law firm, and the Expert shall not, and, unless the Limited Partner agrees otherwise, the firm that employs the Expert shall not, have any material relationship with either the Corporation or the Limited Partner or other actual or potential conflict of interest. If the parties are unable to agree on an Expert within fifteen (15) 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 30 calendar days and shall resolve any matter relating to a Tax Benefit Schedule or an amendment thereto within 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 such date and such Tax Return may be filed as prepared by the Corporation, 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 equally by the Corporation and such Limited Partner except as provided in the next sentence. The Corporation and each Limited Partner shall bear their own costs and expenses of such proceeding, unless a Limited Partner has a prevailing position that is more than 10% of the payment at issue, in which case the Corporation shall reimburse such Limited Partner 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 Corporation and the Limited Partner and may be entered and enforced in any court having jurisdiction.

7.10 Withholding. The Corporation shall be entitled to deduct and withhold from any payment payable pursuant to this Agreement such amounts as the Corporation 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 Corporation, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Exchanging Partner.

7.11 Tax Covenant. The Corporation, Holdings and each of the Limited Partners hereby acknowledge that, as of the date of this Agreement, the aggregate value of the Tax Benefit Payments cannot reasonably be ascertained for U.S. federal income Tax or other applicable Tax purposes.

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

(a) If the Corporation 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, local or foreign 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 an Exchange Payment hereunder transfers one or more assets to a corporation 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 Exchange 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 transfer. The consideration deemed to be received by such entity shall be equal to the fair market value of the transferred asset, plus (i) the amount of debt to which such asset is subject, in the case of a transfer of an encumbered asset or (ii) the amount of debt allocated to such asset, in the case of a transfer of a partnership interest.

7.13 Confidentiality. Each Limited Partner and assignee acknowledges and agrees that the information of the Corporation is confidential and, except in the course of performing any duties as necessary for the Corporation 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 Corporation and its Affiliates and successors, concerning Holdings and its Affiliates and successors or the other Limited Partners, learned by the Limited Partner heretofore or hereafter. This clause 7.13 shall not apply to (i) any information that has been made publicly available by the Corporation or any of its Affiliates, becomes public knowledge (except as a result of an act of such Limited Partner in violation of this Agreement) or is generally known to the business community and (ii) the disclosure of information to the extent necessary for a Limited Partner to prepare and file his or her 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 Limited Partner and assignee (and each employee, representative or other agent of such Limited Partner or assignee, as applicable) may disclose to any and all Persons, without limitation of any kind, the Tax treatment and Tax structure of the Corporation, Holdings, the Limited Partners 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 Limited Partners relating to such Tax treatment and Tax structure.

If a Limited Partner or assignee commits a breach, or threatens to commit a breach, of any of the provisions of this Section 7.13, the Corporation shall have the right and remedy to have the provisions of this Section 7.13 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 Corporation or any of its Subsidiaries or the other Limited Partners and the accounts and funds managed by the Corporation 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.

7.14 Partnership Agreement. To the extent applicable, this Agreement shall be treated as part of the partnership agreement of Holdings 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.

7.15 Independent Nature of Exchanging Limited Partners’ Rights and Obligations. The obligations of each Limited Partner hereunder are several and not joint with the obligations of any other Limited Partner, and no Limited Partner shall be responsible in any way for the performance of the obligations of any other Limited Partner hereunder. The decision of each Limited Partner to enter into this Agreement has been made by such Limited Partner independently of any other Limited Partner. Nothing contained herein, and no action taken by any Limited Partner pursuant hereto, shall be deemed to constitute the Limited Partners as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Limited Partners are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby and the Corporation acknowledges that the Limited Partners are not acting in concert or as a group, and the Corporation will not assert any such claim, with respect to such obligations or the transactions contemplated hereby.

7.16 Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

IN WITNESS WHEREOF, the Corporation, Holdings, Riverstone and HMH have duly executed this Agreement as of the date first written above.
