provide the other party with all information regarding any Acquired Company that either Party may be required to report to any Governmental Authority.

(e) Any refund of Taxes of any Acquired Company (including any interest with respect thereto) for any taxable period ending on or prior to the Closing Date or for the portion of any Straddle Period ending on the Closing Date (determined in accordance with the provisions of Section 5.7(b)) that is not attributable to the carryback of Losses from taxable periods beginning after the Closing Date or the portion of any Straddle Period beginning after the Closing Date (determined in accordance with Section 5.7(b)) shall be the property of Seller, shall be paid over promptly to Seller and if received by the Buyer or any Acquired Company after the Closing Date shall be payable promptly to Seller.

(f) The Parties agree that any Tax of any Acquired Company that is imposed on any transaction involving any Acquired Company (other than transactions in the ordinary course of business) that occurs on the Closing Date but after the General Partner’s acquisition of the Contributable LLC Interests and Buyer’s acquisition of the Other LLC Interests shall be the responsibility of the Buyer.

(g) All payments of Expenses made by an Acquired Company on or before the Closing Date shall be allocated entirely to the taxable period that ends on the Closing Date or the portion of any Straddle Period ending on the Closing Date (determined in accordance with the provisions of Section 5.7(b)).

(a) Seller agrees, at its sole cost and expense (including costs associated with Seller’s internal accounting staff) to prepare unaudited combined balance sheets and related unaudited combined income statements, statements of cash flows and statements of changes in members’ equity for the Acquired Companies, together with the notes thereto, as of and for the period from August 31, 2006 to the last quarter ending prior to the Closing Date (the “Relevant Period”); provided, however, that if the last quarter ending prior to the Closing Date shall end within 25 days of the Closing Date, then the Relevant Period shall end as of the end of the previous quarter (such statements being hereinafter referred to as the “Full Unaudited Financial Statements”). Seller shall use reasonable best efforts to complete the preparation of the Full Unaudited Financial Statements so that they can be delivered to the Partnership prior to Closing.

(b) From and after the date hereof until the Closing, Seller shall cause the Acquired Companies (i) to deliver to the General Partner and Buyer any unaudited financial statements of the Acquired Companies prepared for any period subsequent to August 31, 2006 promptly after such financial statements have been prepared.

(c) All financial statements prepared and delivered pursuant to subsections (a) and (b) of this Section 5.8 shall be prepared in accordance with the books and records of the Acquired Companies. Seller shall use commercially reasonable efforts to assist Buyer and Buyer’s auditors in preparing (i) balance sheets included in such financial statements (including any related notes and schedules) that fairly present in all material respects the combined financial position of the Acquired Companies, as of the date thereof, and (ii) combined income statements,

statements of cash flows and statements of changes in members’ equity included in such financial statements (including any related notes and schedules) that fairly present in all material respects the combined results of operations, cash flows and changes in membership interests, as the case may be, of the Acquired Companies for the periods set forth therein, in each case in accordance with GAAP, subject, in the case of interim financial statements, to normal year-end adjustments and the absence of notes or other textual disclosures required under GAAP that are not, indirectly or in the aggregate, material; provided, however, that Buyer acknowledges and agrees that this Section 5.8(c) shall not be deemed to be a representation or warranty of any kind by any Seller Party with respect to such financial statements.

(d) From and after the date hereof and continuing after the Closing, at Seller’s sole cost and expense (including costs associated with Seller’s internal accounting staff), Seller will cooperate, and will cause its Affiliates to cooperate, with Seller in producing such financial information relating to any Acquired Company as may be reasonably necessary in order to permit Seller to prepare such financial statements of the Acquired Companies as may be required (i) to be included by the Partnership in reports filed by it under the Exchange Act or (ii) in connection with the financing or public or Rule 144A offering of securities by the Partnership or any of its Affiliates. The provisions of this paragraph shall survive the Closing.

5.9 Transfer Taxes. All sales, transfer, use, gross receipts, registration, and similar Taxes (including real estate transfer Taxes), if any, that are payable by any Party hereto or any of the Acquired Companies arising out of or in connection with the consummation of the transactions contemplated hereby shall be borne by Seller.

5.10 Tax Treatment of Aggregate Consideration. Within sixty (60) calendar days after the Closing Date, Buyer shall deliver to Seller a tax allocation of the Aggregate Consideration (and the assumed liabilities) among the assets of the Acquired Companies that complies with Section 1060 of the Code. If Seller does not deliver to Buyer a written objection to such allocation within thirty (30) calendar days after delivery thereof to Seller, then such allocation shall govern. If Seller delivers a written objection to Buyer to such allocation within thirty (30) calendar days after delivery of the allocation to Seller, then Seller and Buyer shall negotiate in good faith in an attempt to reach agreement upon such allocation. If the allocation is not agreed upon during the thirty (30) calendar day period after Seller’s written objection is delivered to Buyer or within a mutually agreed-to extended time period, Seller and Buyer agree that the allocation shall be based upon an asset valuation supplied by an independent accounting firm of recognized national standing to be mutually agreed upon by Buyer and Seller. Each Seller Party, the Partnership, the General Partner and Buyer shall act in accordance with such allocation in the filing of all income Tax Returns (including filing Form 8594 with their Federal income tax return for the taxable year that includes the date of the Closing), except as otherwise required by a determination, as defined in Section 1313 of the Code. The cost of such appraisal, if necessary, shall be shared equally by Buyer and Seller.

5.11 Transaction Units; General Partner Limited Partnership Interest.

(a) Seller agrees that neither the Transaction Units nor the General Partner Limited Partnership Interest shall be offered for sale, sold, assigned, pledged, hypothecated, transferred, exchanged or otherwise disposed of unless the offer and sale is registered under the

Securities Act and applicable state securities laws or an exemption from such registration is available and complied with, and that, unless so registered, no sale, assignment, pledge, hypothecation, transfer, exchange or other disposition, or offer thereof, of the Transaction Units or the General Partner Limited Partnership Interest can be made unless the Partnership or the General Partner, as the case may be, receives an opinion in form and substance satisfactory to it in its sole discretion from a nationally recognized law firm that registration is not required under the Securities Act or any applicable state securities laws; provided, however, that the Partnership or the General Partner, as the case may be, may in its sole discretion waive the requirement of a legal opinion.

(b) Seller acknowledges the following:

(i) The following legend may be placed on the certificates representing the Transaction Units:

THE UNITS (THE “UNITS”) EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES THAT IT WILL NOT DISTRIBUTE, OFFER, RESELL, PLEDGE OR OTHERWISE TRANSFER (INDIVIDUALLY AND COLLECTIVELY, A “TRANSFER”) THE UNITS EVIDENCED HEREBY, EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (B) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT SUCH AS THE EXEMPTION SET FORTH IN RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE). IF THE PROPOSED TRANSFER IS TO BE MADE OTHER THAN PURSUANT TO CLAUSE (A) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE ISSUER AND THE TRANSFER AGENT SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OR ANY STATE OR FOREIGN SECURITIES LAW.

The legend set forth above may be removed if and when the Transaction Units represented by such certificate are disposed of pursuant to an effective registration statement under the Securities Act, the opinion of counsel referred to above has been provided to the Partnership, or, in the opinion of counsel to the Partnership, the same are no longer required under the applicable requirements of such securities laws. The unit certificates shall also bear any additional legends required by applicable federal or state securities laws, which legends may be removed when, in the opinion of counsel to the Partnership, the same are no longer required under the applicable requirements of such securities laws.

(ii) Stop transfer instructions have been or will be placed with respect to the Transaction Units so as to restrict the distribution, resale, pledge, hypothecation or other transfer thereof.

(iii) The legend and stop transfer instructions described in subparagraphs (i) and (ii) above will be replaced with respect to any new certificate issued upon presentment by the undersigned of a certificate for transfer.

(iv) The General Partner Limited Partnership Interest will be subject to the transfer restrictions set forth in the General Partner Partnership Agreement, as amended by the General Partner Partnership Agreement Amendment. Any certificates representing the General Partner Limited Partnership Interest shall bear any legends required by applicable federal or state securities laws, which legends may be removed when, in the opinion of counsel to the General Partner, the same are no longer required under the applicable requirements of such securities laws.

(c) Seller is aware that the Partnership and the General Partner have relied on the representations and warranties of Seller set forth in Section 3.25 and Section 3.26 and on the covenants of Seller set forth in Section 3.26 and this Section 5.11 in determining that an exemption from registration under the Securities Act, applicable state securities laws and the rules promulgated thereunder is available for the issuance of the Transaction Units by the Partnership to Seller and for the issuance of the General Partner Limited Partnership Interest by the General Partner to Seller, and that, but for such representations and covenants, no issuance of the Transaction Units would be made by the Partnership to Seller pursuant to this Agreement and no issuance of the General Partner Limited Partnership Interest would be made by the General Partner to Seller pursuant to this Agreement.

5.12 General Partner Partnership Agreement Amendment. At the Closing, the General Partner shall cause the Managing General Partner to execute and deliver to Seller an amendment to the General Partner Partnership Agreement (the “General Partner Partnership Agreement Amendment”) providing for (i) the issuance of the General Partner Limited Partnership Interest to Seller at the Closing, and (ii) certain special allocations to be made in favor of Seller with respect to its interest in the Incentive Distribution Rights held by the General Partner such that Seller will be entitled to receive all cash distributions and other income and deductions related to an incremental 13.846% of the General Partner’s Incentive Distribution Rights (or 9% of all of the Incentive Distribution Rights).

5.13 Notice of Production. Seller shall notify Buyer in writing (the “Notice of Production”) of the production and sale of the first ton of coal from the Ohio Coal Reserves not less than 30 days, but not more than 60 days, prior to such production and sale.

5.14 Ohio Backstop Agreement. At the Closing, Seller shall execute and deliver the Ohio Backstop Agreement in the form attached hereto as Exhibit C (the “Ohio Backstop Agreement”), which requires Seller to finance certain of Rivervista’s obligations under the ▇▇▇▇▇▇▇ Acquisition Agreement (Ohio).

5.15 Construction Agreement. As soon as is practicable after the execution of this Agreement, Seller will deliver to the General Partner a copy of the agreement relating to the

construction of the Deepwater Clean Coal Handling System (the “Construction Contract”) and shall thereafter deliver copies of any material amendments to the Construction Contract or any material change orders relating to the Construction Contract, if any, at least once every 30 days until the earlier of the Closing or the termination of this Agreement.

5.16 Deepwater TIC Agreement. At the Closing, Seller shall execute and deliver, and Buyer shall execute and deliver, and, immediately following the Closing, Buyer shall cause Deepwater to execute and deliver, the Deepwater TIC Agreement in the form attached hereto as Exhibit D (the “Deepwater TIC Agreement”). If, after the Closing, Buyer causes Deepwater to terminate the Deepwater TIC by posting an escrow pursuant to the terms thereof, then Seller shall cause each Affiliate that is a counterparty to the Deepwater TIC, consistent with such Affiliate’s other obligations, (a) to enter into an account control agreement pursuant to the Deepwater TIC and Section 5.11 of the Sowood Loan Agreement, (b) upon entering into such account control agreement, to request termination of all Liens in respect of such Affiliate’s interest in the Deepwater TIC in accordance with Section 8.15(b) of the Guaranty and Security Agreement and Section 10.15(a) of the Credit Agreement, including delivery of the certification required by Section 10.15(a) of the Credit Agreement, and (c) otherwise to use commercially reasonable efforts to cause to be released all such Liens and to provide evidence satisfactory to Buyer that all such Liens have been released.

5.17 Notification. From the date of this Agreement until the earlier of the Closing or the termination of this Agreement, Seller will promptly notify Buyer in writing if Seller or any Acquired Company becomes aware of any fact or condition that causes the conditions contained in Section 6.2(a) or Section 6.2(b) not to be satisfied as of the date of this Agreement, or if Seller or any Acquired Company becomes aware of the occurrence after the date of this Agreement of any fact or condition that would (except as expressly contemplated by this Agreement) cause the conditions contained in Section 6.2(a) or Section 6.2(b) not to be satisfied as of the time of occurrence or discovery of such fact or condition, setting forth in reasonable detail the facts and circumstances that have resulted in such conditions not being satisfied. Should any such fact or condition require any change in the Acquired Company Disclosure Schedule if the Acquired Company Disclosure Schedule were dated the date of the occurrence or discovery of any such fact or condition, Seller will deliver to Buyer a supplement to the Acquired Company Disclosure Schedule specifying such change promptly, but not less frequently than once every quarter, and at least 10 days in advance of Closing. The delivery by Seller of any such supplement shall not relieve Seller of its obligations under this Section 5.17 to notify Buyer of any facts or conditions that relate to any matter described therein of which Seller becomes aware after delivery of such supplement. During the same period, Seller will promptly notify Buyer of the occurrence of any breach by any Seller Party of any covenant in this Article V or of the occurrence of any event that may make the satisfaction of the conditions in Article VI impossible or unlikely. No notification by Seller pursuant to this Section 5.17 shall affect the rights of Buyer with respect to the representations of Seller Parties set forth in Section 6.2(a) or Section 6.2(b) or the obligations, covenants and agreements of each Seller Party under Section 6.2(c).

(ii) None of the Seller Parties may assert, and each shall be deemed to have waived in full, any claim with respect to a breach of a representation, warranty, covenant or agreement contained herein if, to Seller’s Knowledge, such breach existed prior to the Closing Date but such Seller Party nevertheless proceeded with the Closing;

(iii) None of the Partnership, the General Partner or Buyer may assert, and each shall be deemed to have waived in full, any claim with respect to a breach of a representation, warranty, covenant or agreement contained herein if, to Buyer’s Knowledge, such breach existed prior to the Closing Date but such Party nevertheless proceeded with the Closing; and

(iv) The provisions of this Article IX shall apply in such a manner as not to give duplicative effect to any item of adjustment.

(f) The amount of Losses required to be paid pursuant to this Article IX shall be reduced to the extent of any tax benefits actually realized, or insurance proceeds directly or indirectly received by the Indemnified Party.

9.5 Notice of Asserted Liability; Opportunity to Defend.

(a) All claims for indemnification hereunder shall be asserted and handled pursuant to this Section 9.5. Any Person claiming indemnification hereunder is referred to herein as the “Indemnified Party” or “Indemnitee” and any Person against whom such claims are asserted hereunder is referred to herein as the “Indemnifying Party” or “Indemnitor.”

(b) If any Claim is asserted against or any Loss is sought to be collected from an Indemnifying Party, the Indemnified Party shall with reasonable promptness (and in any event prior to the expiration of the relevant survival period set forth in Section 9.1(a)) provide to the Indemnifying Party a Claim Notice. The failure to notify the Indemnifying Party shall not relieve it of any liability that it may have to any Indemnified Party with respect to such Claim or Loss except to the extent the Indemnifying Party shall have been materially prejudiced by such failure or to the extent the Claim Notice was provided after the expiration of the relevant survival period set forth in Section 9.1.

(c) The Indemnifying Party shall have 30 days from receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party in writing (i) whether or not the Indemnifying Party disputes the liability to the Indemnified Party hereunder with respect to the Claim or Loss, (ii) in any case in which Losses are asserted against or sought to be collected from an Indemnifying Party by an Indemnified Party, whether or not the Indemnifying Party desires at its own sole cost and expense to attempt to remedy such Losses or (iii) in any case in

which Claims are asserted against or sought to be collected from an Indemnified Party by a Third Person (“Third Person Claim”), whether or not the Indemnifying Party desires at its own sole cost and expense to defend the Indemnified Party against such Third Person Claim.

(d) If the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against a Third Person Claim, the Indemnifying Party shall have the right to defend all appropriate Proceedings with counsel of its own choosing (but reasonably satisfactory to the Indemnified Party) and such Proceedings shall be diligently prosecuted by it to settlement or a final conclusion. If the Indemnified Party desires to participate in any such defense or settlement, other than at the request of the Indemnifying Party, it may do so at its sole cost and expense. If the Indemnified Party joins in defending in any such Third Person Claim, the Indemnifying Party shall have full authority to determine all action to be taken with respect thereto. If the Indemnifying Party elects not to defend the Indemnified Party against a Third Person Claim or does not provide an answer within the Notice Period, the Indemnified Party shall be entitled to assume the defense of all appropriate Proceedings related thereto with counsel of its choosing. If a Proceeding is asserted against both the Indemnifying Party and the Indemnified Party and there are one or more defenses available to the Indemnified Party that are not available to the Indemnifying Party or there is a conflict of interest that renders it inappropriate for the same counsel to represent both the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be responsible for paying for separate counsel for the Indemnified Party; provided, however, that, if there is more than one Indemnified Party, the Indemnifying Party shall not be responsible for paying for more than one separate firm of attorneys (in addition to local counsel) to represent the Indemnified Parties, regardless of the number of Indemnified Parties. No compromise or settlement of any Proceeding or Third Party Claim may be effected by the Indemnifying Party without the Indemnified Party’s written consent, which consent shall not be unreasonably withheld, unless the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and such settlement includes the granting by each claimant or plaintiff to each Indemnified Party of an unconditional release from all liability in respect of such Third Person Claim and the related Proceeding, in which case the Indemnifying Party may compromise or settle such Proceeding without the Indemnified Party’s consent.

(e) If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel, at the cost and expense (it being understood that nominal internal costs and expenses and reasonable time expenditures of internal staff shall not be charged) of the Indemnifying Party, in contesting any Third Person Claim, in making any counterclaim against the Third Person asserting the Third Person Claim or in making any cross-complaint against any Person.

(f) The costs and expenses of an Indemnitee, including the fees, costs and expenses of its separate counsel, experts (including expert witnesses), consultants and any other representatives engaged by it, incurred in connection with the defense and settlement or final resolution of any Third Person Claim as to which such Indemnitee has the right to control shall be treated as “Losses” for all purposes hereunder.

9.6 Exclusive Remedy. AS BETWEEN THE BUYER INDEMNITEES AND THE SELLER PARTIES, ON ONE HAND, AND THE SELLER INDEMNITEES AND

THE PARTNERSHIP, THE GENERAL PARTNER AND BUYER, ON THE OTHER, AFTER CLOSING, OTHER THAN WITH RESPECT TO CLAIMS FOR FRAUD, (A) THE PROVISIONS SET FORTH IN THIS ARTICLE IX SHALL BE THE SOLE AND EXCLUSIVE RIGHTS, OBLIGATIONS AND REMEDIES OF THE PARTIES WITH RESPECT TO THIS AGREEMENT, THE EVENTS GIVING RISE THERETO, AND THE TRANSACTIONS PROVIDED FOR HEREIN OR CONTEMPLATED HEREBY AND (B) NO PARTY OR ANY OF ITS SUCCESSORS OR ASSIGNS SHALL HAVE ANY RIGHTS AGAINST ANY OTHER PARTY OR ITS AFFILIATES OTHER THAN AS IS EXPRESSLY PROVIDED IN THIS ARTICLE IX.

9.7 Limitation on Damages. SUBJECT TO SECTION 9.6, NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IN NO EVENT SHALL ANY PARTY BE LIABLE TO ANY OTHER PARTY, OR TO ANY INDEMNITEE, UNDER THIS AGREEMENT FOR ANY EXEMPLARY, PUNITIVE, CONSEQUENTIAL, REMOTE, SPECULATIVE OR SPECIAL DAMAGES, AND NO CLAIM SHALL BE MADE OR AWARDED AGAINST ANY PARTY, FOR ANY SUCH DAMAGES.

9.8 Bold and/or Capitalized Letters. THE PARTIES ACKNOWLEDGE THAT THE BOLD AND CAPITALIZED LETTERS IN THIS AGREEMENT CONSTITUTE CONSPICUOUS LEGENDS.

9.9 Independent Investigation. The Partnership, the General Partner and Buyer are knowledgeable in the business of owning, leasing, preparing, loading and transporting coal. In making the decision to enter into this Agreement and to consummate the transactions contemplated hereby, the Partnership, the General Partner and Buyer have relied solely on their own independent due diligence investigations and inspection of the Assets of the Acquired Companies, and the representations, warranties, covenants and undertakings of the Seller Parties in this Agreement.

9.10 Disclaimer. EXCEPT AS EXPRESSLY SET OUT IN THIS AGREEMENT, NO SELLER PARTY MAKES ANY REPRESENTATION, COVENANT OR WARRANTY, EXPRESS, IMPLIED OR STATUTORY, AS TO THE ACCURACY OR COMPLETENESS OF ANY DATA OR RECORDS DELIVERED TO THE PARTNERSHIP, THE GENERAL PARTNER OR BUYER WITH RESPECT TO (A) THE ASSETS, INCLUDING ANY DESCRIPTION OF THE ASSETS, PRICING ASSUMPTIONS, QUALITY OR QUANTITY OF THE COAL RESERVES INCLUDED IN THE ASSETS, OR (B) FUTURE AMOUNTS OF COAL OR OTHER PRODUCTS PRODUCED, PROCESSED, STORED OR TRANSPORTED, THROUGH OR AT THE ASSETS.

ARTICLE X

MISCELLANEOUS PROVISIONS

10.1 Expenses. Each Party will bear its own respective costs and expenses (including legal fees and expenses) incurred in connection with the negotiation of this Agreement and the transactions contemplated hereby.

10.2 Assignment. No Party may assign this Agreement or any of its rights or obligations arising hereunder without the prior written consent of the other Parties; provided, however, that without the consent of any Seller Party, Buyer may, without relieving Buyer from its liabilities or obligations hereunder, assign this Agreement, and its rights and obligations hereunder, to an Affiliate of Buyer or to an entity formed, controlled and primarily owned by Buyer. Any purported assignment in violation of this Section shall be void ab initio.

10.3 Entire Agreement, Amendments and Waiver. This Agreement (together with any Exhibits and schedules hereto), the other Transaction Documents and all certificates, documents, instruments and writings that are delivered pursuant hereto or thereto contain the entire understanding of the Parties with respect to the transactions contemplated hereby and supersede all prior agreements, arrangements and understandings relating to the subject matter hereof other than the Confidentiality Agreement which is hereby ratified by Buyer, as if Buyer were a party thereto, and shall hereafter bind the Partnership and Buyer, as well as the parties thereto. This Agreement may be amended or superseded only by a written instrument duly executed by each Party specifically stating that such Party amends or supersedes this Agreement. Any of the terms of this Agreement and any condition to a Party’s obligations hereunder may be waived only in writing by that Party specifically stating that it waives a term or condition hereof. No waiver by a Party of any one or more conditions or defaults by the other in performance of any of the provisions of this Agreement shall operate or be construed as a waiver of any future conditions or defaults, whether of a like or different character, nor shall the waiver constitute a continuing waiver unless otherwise expressly provided.

10.4 Severability. Each portion of this Agreement is intended to be severable. If any term or provision hereof is illegal or invalid for any reason whatsoever, such illegality or invalidity shall not affect the validity of the remainder of this Agreement.

10.5 Counterparts. This Agreement may be executed simultaneously in any number of counterparts (including facsimile counterparts), each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

10.6 Governing Law and Dispute Resolution.

(a) Governing Law. This Agreement shall be governed by, enforced in accordance with, and interpreted under, the Laws of the State of West Virginia, without reference to applicable principles of conflicts of Laws.

(b) Consent to Jurisdiction. The Parties hereby irrevocably submit to the jurisdiction of the courts of the State of Texas and the federal courts of the United States of America located in Houston, Texas, and appropriate courts of appeal therefrom, over any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby, and each Party hereby irrevocably agrees that all claims in respect of such dispute or proceeding may be heard and determined in such courts. The Parties hereby irrevocably waive, to the fullest extent permitted by Law, any objection that they may now or hereafter have to the laying of venue of any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each Party agrees that a judgment in any such dispute may be

enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. This consent to jurisdiction is being given solely for purposes of this Agreement and is not intended to confer, and shall not confer, consent to jurisdiction with respect to any other dispute in which a Party to this Agreement may become involved. Each Party consents to process being served by any other Party to this Agreement in any Proceeding of the nature specified in this Section 10.6(b) by the mailing of a copy thereof in the manner specified by the provisions of Section 10.7.

(c) Recovery of Costs and Attorneys’ Fees. If there are any Proceedings arising out of or relating to this Agreement or the transactions contemplated hereby after the entry of a final written non-appealable order and if one Party has predominantly prevailed in the dispute, that Party shall be entitled to recover from the other Party all court costs, fees and expenses relating to such Proceeding, including reasonable attorneys’ fees that are specifically included in such court award.

(d) Settlement Proceedings. All aspects of any settlement proceedings, including discovery, testimony and other evidence, negotiations and communications pursuant to this Section 10.6, briefs and the award shall be held confidential by each Party, and shall be treated as compromise and settlement negotiations for the purposes of the federal and state rules of evidence.

10.7 Notices and Addresses.

Notice by mail shall be deemed to have been given and received on the third day after posting. Notice by messenger, overnight delivery service, facsimile transmission or personal delivery shall be deemed given on the date of actual delivery.

10.8 Press Releases. Except as may otherwise be required by securities Laws and public announcements or disclosures that are, in the reasonable opinion of the Party proposing to make the announcement or disclosure, legally required to be made, there shall be prior to Closing no press release or public communication concerning the transactions contemplated by this Agreement by any Party except with the prior written consent of the Party not originating such press release or communication, which consent shall not be unreasonably withheld or delayed. Prior to Closing the Partnership and Seller will consult in advance on the necessity for, and the timing and content of, any communications to be made to the public.

10.9 Offset. Nothing contained herein shall impair or constitute a waiver of any right of offset or setoff for any Party.

10.10 No Partnership; Third Party Beneficiaries. Except to the extent expressly set forth in the Partnership Agreement and the General Partner Partnership Agreement, as amended by the General Partner Partnership Agreement Amendment, nothing in this Agreement or the other Transaction Documents shall be deemed to create a joint venture, partnership, tax partnership, or agency relationship among the Parties. Nothing in this Agreement shall provide any benefit to any Third Person or entitle any Third Person to any claim, cause of action, remedy or right of any kind, it being the intent of the Parties that this Agreement shall not be construed as a third-party beneficiary contract; provided, however, that the indemnification provisions of Article IX shall inure to the benefit of the Buyer Indemnitees and the Seller Indemnitees as provided therein.

10.11 Negotiated Transaction. The Parties, each represented by legal counsel, have each participated in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation should arise, this Agreement shall be construed as if drafted by all Parties and no presumption or burden of proof shall arise favoring or burdening any Party hereto by virtue of the authorship of any of the provisions of this Agreement.

10.12 Disclosure Schedules. The information in the Acquired Company Disclosure Schedule and the Partnership Disclosure Schedule constitutes (a) exceptions or qualifications to particular representations, warranties, covenants and obligations of the Seller Parties or the Partnership, the General Partner and Buyer, as applicable, as set forth in this Agreement or (b) descriptions or lists of assets and liabilities and other items referred to in this Agreement. The Disclosure Schedules shall not be construed as indicating that any disclosed information is required to be disclosed, and no disclosure shall be construed as an admission that such information is material to, or required to be disclosed by, the disclosing Party. Capitalized terms used in each Disclosure Schedule that are not defined therein are defined in this Agreement and shall have the meaning given to them in this Agreement. The statements in each Disclosure Schedule relate only to the provisions in the Section of this Agreement to which they expressly relate and not to any other provision in this Agreement, unless its applicability to another Section of this Agreement is readily apparent.

10.13 Time of the Essence. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.

10.14 Affiliate Liability.

(a) Each of the following is herein referred to as a “Buyer Affiliate”: (i) any direct or indirect holder of the general partner interest in the Partnership (whether limited or general partners, members or otherwise), and (ii) any director, officer, manager, employee, representative or agent of (A) the Partnership, the General Partner or Buyer or (B) any Person who directly or indirectly controls the Partnership. Except to the extent that a Buyer Affiliate is an express signatory hereto or thereto or an express assignee of the Partnership or Buyer, no Buyer Affiliate shall have any liability or obligation to any Seller Party of any nature whatsoever in connection with or under this Agreement, any of the other Transaction Documents or the transactions contemplated herein or therein, and each Seller Party on behalf of itself and each Acquired Company and Seller Affiliate hereby waives and releases all claims of any such liability and obligation. Notwithstanding the foregoing, no Seller Party shall be deemed an Affiliate of the Partnership.

(b) Each of the following is herein referred to as a “Seller Affiliate”: (i) any direct or indirect holder of Equity Interests in any Seller Party (whether limited or general partners, members, stockholders or otherwise), and (ii) any partner, member, shareholder, director, officer, manager, employee, representative or agent of (A) any Seller Party or any Acquired Company or any Subsidiary of either of them or (B) any Person who directly or indirectly controls any Seller Party. Except to the extent that a Seller Affiliate is an express signatory hereto or an express assignee of any Seller Party, no Seller Affiliate shall have any liability or obligation to the Partnership, the General Partner, Buyer or Buyer Indemnitee of any nature whatsoever in connection with or under this Agreement, any of the other Transaction

Documents or the transactions contemplated herein or therein, and the Partnership, the General Partner and Buyer on behalf of themselves and the Buyer Affiliates hereby waive and release all claims of any such liability and obligation.

10.15 No Waiver of Claims for Fraud. The liability of any Party under Article IX shall be in addition to, and not exclusive of, any other liability that such Party may have at law or equity based on such Party’s fraudulent acts or omissions. None of the provisions set forth in this Agreement shall be deemed a waiver by any Party of any right or remedy which such Party may have at law or equity based on any other Party’s fraudulent acts or omissions, nor shall any such provisions limit, or be deemed to limit, (a) the amounts of recovery sought or awarded in any such claim for fraud, (b) the time period during which a claim for fraud may be brought, or (c) the recourse which any such Party may seek against another Party with respect to a claim for fraud; provided, however, that with respect to such rights and remedies at law or equity, the Parties further acknowledge and agree that none of the provisions of this Section 10.15 shall be deemed a waiver of any defenses which may be available in respect of actions or claims for fraud, including defenses of statutes of limitations or limitations of damages.

10.16 No Recovery. No Seller Party shall be entitled to indemnification or contribution from any Acquired Company for any Losses that it is obligated to pay pursuant to any Claim brought by a Buyer Indemnitee. The foregoing shall not apply to Claims made against the Partnership, the General Partner or Buyer for a breach of any of the representations, warranties, covenants and agreements of the Partnership, the General Partner or Buyer set forth in this Agreement (each such Claim, a “Permitted Indemnification/Contribution”). If any right of indemnification or contribution from any Acquired Company under the Organizational Documents of such Acquired Company relating to a Claim (other than a claim for Permitted Indemnification/Contribution) is ultimately determined to be unwaivable, the Seller Parties shall indemnify the Buyer or the applicable Acquired Company to the full extent of such recovery. Except as set forth in this Section 10.16, each Seller Party hereby waives and releases any and all rights that it may have to assert claims of indemnification or contribution against any Acquired Company under this Agreement, any other Transaction Document, any other Contract or any provision of its Organizational Documents for any Losses that such Seller Party is obligated to pay pursuant to any Claim brought by a Buyer Indemnitee (other than a claim for Permitted Indemnification/Contribution).

10.17 Guarantee of Obligations. Parent hereby agrees to guarantee the obligations of Seller under this Agreement, including any obligation to indemnify any Buyer Indemnitee for which Seller may become liable in accordance with the terms hereof. If Seller shall fail or be unable to pay any amounts due to any Buyer Indemnitee under this Agreement when the same shall become due and payable, Parent shall be obligated to pay or cause to be paid such amounts to each such Buyer Indemnitee in accordance with the terms hereof. This guarantee is a guarantee of payment, performance and compliance and not of collectibility and is in no way conditioned or contingent upon any attempt to collect from or enforce performance or compliance by Seller or upon any other event or condition whatsoever. Upon Parent’s execution and delivery to the Partnership, the General Partner and Buyer of a release substantially in the form attached hereto as Exhibit E the (“Parent Release”) on or after the third anniversary of the Closing (the date of such delivery, the “Parent Release Date”), the obligations of Parent under this Section 10.17 shall terminate, and Parent shall have no further liability or obligation under

this Agreement with respect to any Claim asserted or Loss sought by any Buyer Indemnitee against Parent in accordance with Article IX following the Parent Release Date.
