     3. Prior to the execution and delivery of this Agreement, each Member has executed and delivered to each of Bear Cub and Buyers a power of attorney in substantially the form attached hereto as Exhibit A appointing Robert J.

     NOW, THEREFORE, in consideration of the mutual promises hereinafter set forth and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

     1.4 Other Terms. Other terms may be defined elsewhere in the text of this Agreement and shall have the meanings indicated throughout this Agreement.

ARTICLE II
THE TRANSACTION

     2.1 The Transaction. Subject to and upon the terms and conditions of this Agreement, at the Closing, each Member shall sell, transfer, convey, assign and deliver to Buyers, and Buyers shall purchase and acquire from each Member, all of such Member’s Equity Interest in Pueblo, including all of such Member’s Interests, free and clear of all Liens. The Interests to be acquired by Buyers at Closing shall constitute all of the outstanding Equity Interests in Pueblo.

     2.2 Consideration.

          (a) The aggregate consideration to be paid by Buyers for the Interests shall consist of (i) Transaction Units and (ii) the Cash Amount (together, the “Aggregate Consideration”). The “Cash Amount” of the Aggregate Consideration shall be $34,735,049.00 (Thirty Four Million Seven Hundred Thirty Five Thousand Forty Nine and no/100 dollars) less (i) the sum of (A) the Debt Payoff Amount, (B) to the extent not paid prior to the Measurement Time, the Expenses, and (C) the Working Capital Deficit, if any, plus (ii) the Working Capital Surplus, if any. The Aggregate Consideration shall be payable in the manner described in Section 2.2(b) and Section 2.3.

          (b) At the Closing:

                (i) (A) Pueblo Holdings shall pay to the Sellers’ Representative, by wire transfer of immediately available funds to the account designated in writing by Sellers’ Representative to Buyer at least two Business Days prior to Closing, an amount in Cash equal to the Estimated Cash Amount minus the Escrow Deposit and (B) the Partnership shall deliver to the Sellers’ Representative irrevocable instructions to the Partnership’s transfer agent to prepare and deliver to the Sellers’ Representative a share certificate in the name of each Member and in the amount set forth opposite such Member’s name as set forth on Schedule A;

                (ii) the Partnership shall deposit with the Escrow Agent the Escrow Deposit to secure and be available to satisfy the rights of Buyers under Section 2.3(d)(i);

                (iii) to the extent unpaid, Pueblo Holdings shall pay to the payees of any Expenses by wire transfer of immediately available funds to the account(s) designated by such Persons in the applicable Payoff Letters; the amounts specified in the Payoff Letters; and

                (iv) Pueblo Holdings shall pay to each holder of any Third-Party Debt, by wire transfer of immediately available funds to the account(s) designated by such Persons in the applicable Debt Payoff Letters, the amounts specified in the Debt Payoff Letters.

     2.3 Adjustments.

          (a) Preparation of Estimated Closing Statement. The Sellers’ Representative shall prepare in good faith and deliver to Pueblo Holdings, at least four Business Days prior to the Closing Date and at the sole expense of Sellers, a statement as of the Closing Date (the “Estimated Closing Statement”), setting forth a detailed determination of the Estimated Cash Amount. The “Estimated Cash Amount” shall be $34,735,049.00 minus (i) the sum of (A) the Debt Payoff Amount, (B) to the extent unpaid as of the Measurement Time, the Expenses, and (C) the estimated amount of Working Capital Deficit, if any, plus (ii) the estimated amount of Working Capital Surplus, if any. The Debt Payoff Amount and the Expenses shall be based on amounts set forth in the Debt Payoff Letters or the Payoff Letters, or, to the extent a Debt Payoff Letter or a Payoff Letter has not been provided for a Third-Party Debt or Expense, an estimate of such amounts, and in each case, shall be subject to final determination in the Final Closing Statement. Each estimation set forth in the Estimated Closing Statement shall be made as of the Measurement Time. Appropriate adjustments to the Aggregate Consideration Price shall be made after the Closing pursuant to Sections 2.3(b), (c), and (d).

          (b) Preparation of Closing Statement. As soon as reasonably practicable after the Closing Date (and, in any event, within 90 days after the Closing Date), Pueblo Holdings shall prepare and deliver to Sellers’ Representative, at the sole expense of Pueblo Holdings, a closing statement as of the Measurement Time (the “Proposed Closing Statement”), setting forth the proposed final calculation of (i) Net Working Capital, (ii) Debt Payoff Amount, (iii) Expenses, and (iv) the Cash Amount of the Aggregate Consideration. If Pueblo Holdings does not deliver the Proposed Closing Statement when required, Sellers’ Representative may prepare and deliver it to Pueblo Holdings, and, in such case, Pueblo Holdings shall have Sellers’ Representative objection rights under this Section 2.3.

          (c) Examination of Proposed Closing Statement. Sellers’ Representative shall review the Proposed Closing Statement to confirm the accuracy of the Proposed Closing Statement and Pueblo Holdings’ calculations. If Sellers’ Representative fails to give Pueblo Holdings written notice of any disputed amounts within 30 days after Sellers’ Representative receives the Proposed Closing Statement (the “Review Period”), then the Proposed Closing Statement shall become the Final Closing Statement for purposes hereof. If Sellers’ Representative gives Pueblo Holdings written notice of any disputed items within the Review Period, Pueblo Holdings and Sellers’ Representative shall attempt in good faith to agree on any adjustments that should be made to the Proposed Closing Statement. If Pueblo Holdings and Sellers’ Representative fail to resolve any disputed amounts within 60 days after Sellers’ Representative receives the Proposed Closing Statement, Pueblo Holdings and Sellers’ Representative will engage the Audit Firm to resolve any such disputed matters in accordance

with the terms of this Agreement, and, in connection with such engagement Pueblo Holdings, Pueblo and Sellers’ Representative shall execute any engagement, indemnity and other agreements as the Audit Firm may require as a condition to such engagement. The Audit Firm’s engagement shall be limited to the resolution of disputed amounts set forth in the Proposed Closing Statement that have been identified by Sellers’ Representative, and no other matter relating to the Final Closing Statement shall be subject to determination by the Audit Firm except to the extent affected by resolution of the disputed amounts. The Parties shall cooperate diligently with any reasonable request of the Audit Firm in an effort to resolve any disputed matter as soon as reasonably possible after the Audit Firm is engaged. If possible, the decision of the Audit Firm shall be made within 30 days after being engaged. In any event, the decision shall be final and binding on the Parties. The Proposed Closing Statement shall be revised, if necessary, to reflect the final determination of (i) Net Working Capital, (ii) Debt Payoff Amount, (iii) Expenses and (iv) the Cash Amount of the Aggregate Consideration (the final form of the Proposed Closing Statement, including any revisions that are made thereto pursuant to this Section 2.3(c), is referred to herein as the “Final Closing Statement”).

          (d) Adjustments.

                (i) If the Cash Amount of the Aggregate Consideration as reflected on the Final Closing Statement is less than the Estimated Cash Amount (the amount of such shortfall, if any, being hereinafter referred to as the “Aggregate Consideration Deficit”), then an amount of Cash equal to such Aggregate Consideration Deficit shall be released promptly from the Escrow Fund and paid to Pueblo Holdings in accordance with Section 2.4(b)(i).

                (ii) If the Cash Amount of the Aggregate Consideration as reflected on the Final Closing Statement is greater than the Estimated Cash Amount (the amount of such excess being hereinafter referred to as the “Aggregate Consideration Surplus”), then Pueblo Holdings shall immediately tender payment of such Aggregate Consideration Surplus, in Cash, to the Sellers’ Representative.

          (e) No Duplicative Effect. The provisions of this Section 2.3 and of any other Transaction Document shall apply in such a manner so as not to include in the components and calculations any duplicative effect of any item of adjustment and, except as otherwise expressly provided in this Agreement or as described in the Sample Balance Sheet, the Parties covenant and agree that no amount shall be (or is intended to be) included, in whole or in part (either as an increase or reduction) more than once in the calculation of Net Working Capital, the Debt Payoff Amount, Expenses, or the Unpaid Environmental Deductible in each case, if any, or the Cash Amount of the Aggregate Consideration or any component of any of the foregoing, or any other calculated amount pursuant to this Agreement if the effect of such additional inclusion (either as an increase or reduction) would be to cause such amount to be overstated or understated for purposes of such calculation. The Parties acknowledge and agree that, if there is a conflict between a determination, calculation or methodology set forth in the Sample Balance Sheet or the definitions contained in this Agreement, as applicable, on the one hand, and those provided by GAAP, on the other hand, (i) the determination, calculation or methodology set forth in the Sample Balance Sheet or the definitions contained in this Agreement, as applicable, shall control to the extent that the matter is included in the Sample Balance Sheet or the definitions contained

in this Agreement as a line item or specific adjustment and (ii) the determination, calculation or methodology prescribed by GAAP shall otherwise control.

          (f) Fees and Expenses of the Audit Firm. If the Parties submit any disputed amounts to the Audit Firm for resolution as provided in Section 2.3(c) above, the fees and expenses of the Audit Firm (the “Audit Fees”) will be paid by and apportioned between Pueblo Holdings and the Sellers based on the aggregate dollar amount of the amount in dispute and the relative recovery as determined by the Audit Firm of Sellers and Pueblo Holdings, respectively. The Sellers and Pueblo Holdings shall promptly, and in any event within five Business Days after the final determination of the Final Closing Statement, pay to the Audit Firm the amount of Audit Fees payable by Sellers and Pueblo Holdings pursuant to the preceding sentence.

     2.4 Escrow.

          (a) Escrow Deposit. At or prior to the Closing, Pueblo Holdings, Sellers’ Representative, Bear Cub and the Escrow Agent shall enter into the Escrow Agreement. Notwithstanding any other provision in this Agreement to the contrary, in order to secure the indemnity obligations of the Sellers to the Buyer Indemnities under this Agreement and the recovery by the Buyers of any Aggregate Consideration Deficit, Buyers shall deposit the Escrow Deposit with the Escrow Agent at Closing to be held in escrow pursuant to the terms of this Agreement and the Escrow Agreement.

          (b) Distribution of Escrow Fund.

                (i) Upon the Buyers becoming entitled to a distribution of all or a portion of the Escrow Fund pursuant to Section 2.3(d)(i), the Escrow Agent shall deliver (A) to the Buyers out of the Escrow Fund, Cash in an amount equal to the Aggregate Consideration Deficit, (B) to the Audit Firm an amount in Cash equal to the amount payable to the Audit Firm by Sellers in accordance with Section 2.3(f), if applicable, and (C) to Sellers’ Representative any Cash remaining in the Escrow Fund after the payments in clauses (A) and (B) of this Section 2.4(b)(i) have been made. If the Aggregate Consideration Deficit is greater than the amount of Cash in the Escrow Fund (such excess, the “Escrow Cash Shortfall”), then, in addition to the Cash distribution as provided above, each Member shall deliver to Pueblo Holdings, within 10 days after written notice of an Escrow Cash Shortfall to the Seller Representative (a “Shortfall Notice”), an amount in Cash equal to the Escrow Cash Shortfall multiplied by such Member’s Pro Rata Portion; provided that if any amounts are unpaid pursuant to this Section 2.4(b)(i), Buyers shall be allowed to pursue a claim for such unpaid amounts in accordance with the procedures set forth in Section 10.4(h). If it is determined that Buyers are not entitled to a distribution of the Escrow Fund pursuant to Section 2.3(d)(i), the Escrow Agent shall deliver (A) to the Audit Firm an amount in Cash equal to the amount payable to the Audit Firm by Sellers in accordance with Section 2.3(f), if applicable, and (B) to Sellers’ Representative all of the Cash remaining in the Escrow Fund upon such distribution.

                (ii) Notwithstanding anything in this Agreement to the contrary, the Escrow Agent shall distribute on a quarterly basis to the Sellers’ Representative, all interest, distributions, dividends and other income earned on the Escrow Fund.

          (c) Written Instructions. Sellers’ Representative and Pueblo Holdings hereby covenant and agree that when any Person becomes entitled to any distribution from the Escrow Fund pursuant to any provision of this Agreement, Pueblo Holdings and Sellers’ Representative shall promptly execute and deliver to the Escrow Agent joint written instructions setting forth the amounts to be paid to such Person, if any, from the Escrow Fund in accordance with this Agreement and all other means of calculating amounts due under this Agreement (a “Joint Direction”). Each of Pueblo Holdings and Sellers’ Representative agree to confer as promptly as practicable and to use its reasonable best efforts to reach agreement as to the calculation of and entitlement to such amounts and the applicable Escrow Fund(s) from which such amounts will be distributed. In furtherance and not in limitation of the foregoing:

                (i) if the Sellers’ Representative or Pueblo Holdings shall fail to execute and deliver a Joint Direction, either of the Sellers’ Representative or Buyers, as applicable, shall be entitled to receive distributions from the Escrow Fund from the Escrow Agent promptly upon delivery to the Escrow Agent of a written instruction, order or judgment issued or entered by a court of competent jurisdiction setting forth the amount to be paid to such Party pursuant to Section 2.4(b)(i) (a “Court Direction”);

                (ii) Pueblo Holdings and Sellers’ Representative covenant and agree jointly to instruct the Escrow Agent in writing, (1) within five Business Days after the final determination, of the Final Closing Statement to make the Cash distributions, if any, required by Section 2.3(d)(i), (2) if applicable, promptly within five Business Days after the determination by the Audit Firm of Net Working Capital, the Credit Agreement Balance, Third-Party Debt, Expenses, the Unpaid Environmental Deductible or the Cash Amount of the Aggregate Consideration, as applicable, to release, if applicable, to the Audit Firm out of the Escrow Fund the amount payable to the Audit Firm by the Sellers in accordance with Section 2.3(f).

     2.5 Delivery to Sellers’ Representative. Each Member acknowledges and agrees that delivery to the Sellers’ Representative of any amounts and all Transaction Units to which such Member is entitled under this Agreement shall constitute delivery to such Member for all purposes and the Buyer shall have no further liability to such Member with respect to such amounts or Transaction Units so delivered to the Sellers’ Representative.

ARTICLE III
REPRESENTATIONS AND WARRANTIES OF MEMBERS

     Subject to the limitations set forth in Article X, each Member, severally and not jointly with any other Member, represents and warrants as to itself to Buyers as follows (such representations and warranties being deemed to be made as of the date hereof and on a continuous basis until the Closing) except as set forth in the Disclosure Letter:

     3.1 Organization, Good Standing and Authority of Sellers.

          (a) Such Member, if other than an individual, is a corporation, limited liability company, limited partnership or trust duly organized or formed, validly existing and in good standing under the laws of its jurisdiction of incorporation, organization or formation, has all

requisite power and authority to own, lease and operate its properties and to carry on its business as now being conducted.

          (b) Such Member has the full right, power and authority to enter into this Agreement and the Transaction Documents to which it shall be a party and to transfer, convey and sell to Buyers at the Closing the Interests owned by it. If such Member is other than an individual, the execution, delivery and performance of this Agreement and the other Transaction Documents to which it is or is intended to be a party have been duly authorized by all requisite corporate, limited liability company or limited partnership action on the part of such Member. This Agreement and the other Transaction Documents to which such Member is or shall be a party have been or will be duly executed and delivered by such Member, and (assuming due authorization, execution and delivery hereof by the other parties hereto and thereto) such Transaction Documents constitute or, if not yet executed, will at Closing constitute, legal, valid and binding obligations of such Member, enforceable against such Member in accordance with their terms, subject, as to enforceability, to bankruptcy, insolvency, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

     3.2 Title to Interests. Such Member has good and valid record and beneficial title to the Interests as set forth beside such Member’s name on Schedule A, free and clear of any and all Liens. The Interests set forth opposite such Member’s name on Schedule A constitute all of the Equity Interests of Pueblo held of record or beneficially by such Member. Upon the Closing, Buyers will acquire good title to all of the Equity Interests of Pueblo as set forth opposite such Member’s name on Schedule A, free and clear of any Liens, other than any Liens created by Buyers. Neither such Member, nor, to the knowledge of such Member, Bear Cub or any other Member is a party to (i) any option, warrant, purchase right or other Contract (other than this Agreement) that could require any such Seller or, after the Closing, Buyers, to sell, transfer or otherwise dispose of any Equity Interest of Pueblo or (ii) any voting trust, proxy or other agreement or understanding with respect to the voting of any Equity Interest of Pueblo. As of the Closing, except for the Interests in Pueblo set forth opposite such Member’s name on Schedule A, such Member will not own any Equity Interests of Pueblo.

     3.3 No Conflicts. Neither the execution and delivery by such Member of this Agreement, any other Transaction Documents to which such Member is or shall be a party or any instrument required hereby or thereby to be executed and delivered by it at Closing nor the performance by such Member of its obligations hereunder or thereunder will require any consent under, conflict with, violate or breach the terms of, cause a default (with or without notice or lapse of time or both) or give rise to right of termination, cancellation or acceleration of any obligation or to the loss of a benefit under, or result in the creation of any Lien on any of such Member’s Interests under (i) if such Member is other than an individual, the Organizational Documents of such Member, (ii) any Contract or other instrument to which such Member is a party or by which it or any of its properties or assets are bound, or (iii) assuming the consents, approvals, authorizations or permits and filings or notifications referred to in Section 4.5 are duly and timely obtained any Law, Regulation or Order applicable to such Member.

     3.4 Investor Status

          (a) The Transaction Units are being acquired by such Member for investment purposes only, for such Member’s own account and not as nominee or agent for any other Person or entity, and not with a view to, or for resale in connection with, any distribution thereof within the meaning of the Securities Act. Such Member is not a party to or bound by, and does not intend or have any plans to enter into, any Contract with any Person to sell, transfer or pledge any part of the Transaction Units, except for bona fide pledges or sales or transfers made in compliance with all applicable securities laws.

          (b) Such Member has such expertise, knowledge and sophistication in financial and business matters generally that it is capable of evaluating, and has evaluated, the merits and economic risks of its investment in the Partnership and the suitability of the Transaction Units as an investment.

          (c) In connection with the acquisition of the Transaction Units hereunder, such Member (or such Member’s Purchaser Representative) has had the opportunity to examine all aspects of the Partnership, its operations, and its financial condition that such Member (or such Member’s Purchaser Representative) has deemed relevant, and has had access to all information with respect to the Partnership and its business in order to make an evaluation thereof. In connection with the acquisition of the Transaction Units hereunder, such Member (or such Member’s Purchaser Representative) has had the opportunity to ask such questions of and receive answers from directors, officers, employees and representatives of the Managing General Partner concerning the Partnership and to obtain such additional information about the Partnership as such Member (or such Member’s Purchaser Representative) deems necessary for an evaluation thereof. The investment decision of such Member to acquire the Transaction Units has been based solely upon the evaluation made by such Member (or such Member’s Purchaser Representative) of the Partnership. In evaluating the suitability of an investment in the Partnership, such Member has not been furnished and no Member (or such Member’s Purchaser Representative) has relied upon any representations or other information (whether oral or written) other than as contained in the representations and warranties of the Buyers in this Agreement.

          (d) Such Member acknowledges that copies have been made available to it, sufficiently in advance of this Agreement as such Member (or such Member’s Purchaser Representative) deems necessary to evaluate an investment in the Transaction Units, of each of the Partnership SEC Documents, and has been informed that copies of Exhibits to each of the Partnership SEC Documents will be made available to any Member (or such Member’s Purchaser Representative) upon such Member’s written request.

          (e) Such Member (i) is an “Accredited Investor” as defined in Rule 501 of Regulation D under the Securities Act or (ii) either alone or with his Purchaser’s Representative has such knowledge and experience in financial and business matters that he is capable of evaluating the merits and risks of an investment in the Partnership.

          (f) Such Member acknowledges that the Transaction Units have not been offered or sold by means of any form of general solicitation or general advertising or by means of publicly disseminated advertisements or sales literature.

     3.5 Status of Transaction Units; Disposition.

          (a) Such Member acknowledges that no registration statement relating to the Transaction Units has been filed under the Securities Act or any state securities law and that, consequently, the Transaction Units are “restricted securities” within the meaning of Rule 144 under the Securities Act, may not be sold, pledged, hypothecated or otherwise transferred (and, therefore, must be held by such Member) unless the Transaction Units subsequently are registered under the Securities Act and such state laws or until an exemption from such registration requirements is available.

          (b) Neither such Member nor anyone acting on such Member’s behalf has offered or sold or will offer or sell any of the Transaction Units by means of any form of general solicitation or general advertising or has taken or will take any action that would constitute a distribution of the Transaction Units under the Securities Act, would render the disposition of the Transaction Units a violation of Section 5 of the Securities Act or any state or other applicable securities law, or would require registration or qualification pursuant thereto.

ARTICLE IV
REPRESENTATIONS AND WARRANTIES OF BEAR CUB

     Subject to the limitations set forth in Article X, Bear Cub represents and warrants to Buyers as follows (such representations and warranties being deemed to be made as of the date hereof and on a continuous basis until the Closing) except as set forth in the Disclosure Letter:

     4.1 Organization, Good Standing and Authority; Capitalization of Bear Cub.

          (a) Bear Cub is a limited liability company duly formed, validly existing and in good standing under the Laws of the State of Colorado and has all requisite limited liability company power and authority to carry on its business as it is now being conducted and to own, operate and lease the assets it now owns, operates or holds under lease.

          (b) Bear Cub has the full right, power and authority to enter into this Agreement and the Transaction Documents to which it shall be a party.

written notification that any event has occurred or any circumstance or condition exists, and, to Bear Cub’s Knowledge, no event has occurred, and no circumstance or condition does exist, that (with or without notice or lapse of time) could reasonably be expected to constitute or result in a material violation or non-compliance by any of the Pueblo Companies with any such Authorization.

REPRESENTATIONS AND WARRANTIES OF THE BUYERS

     The Buyers jointly and severally represent and warrant to Sellers as follows (such representations and warranties being deemed to be made as of the date hereof and on a continuous basis until the Closing), in each case except as to matters disclosed in the Partnership SEC Documents:

Each of the Partnership and Pueblo Holdings and its Significant Subsidiaries is a corporation, limited liability company or limited partnership duly organized or formed, validly existing and in good standing under the laws of its jurisdiction of incorporation, organization or formation, has all requisite power and authority to own, lease and operate its properties and to carry on its business as now being conducted, and is duly qualified and licensed, as may be required, and in good standing to do business in each jurisdiction in which the business it is conducting, or the operation, ownership or leasing of its properties, makes such qualification and licensing necessary, other than in such jurisdictions in which the failure so to be qualified and licensed could not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect on the Partnership. Each of the Partnership and Pueblo Holdings has heretofore made available to Sellers complete and correct copies of its Organizational Documents, each as amended to date.

     5.2 Authority; No Violations, Consents and Approvals.

          (a) Other than approval by the General Partner, which approval has been obtained, no vote of holders of any Equity Interest of the Partnership is necessary to approve this Agreement, the other Transaction Documents to which the Buyers are or will be a party, or the performance by the Buyers of their respective obligations hereunder or thereunder. The Buyers have all requisite limited partnership and corporate power and authority to enter into this Agreement and the other Transaction Documents to which it shall be a party and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary partnership and corporate action on the part of each of the Buyers. This Agreement has been duly executed and delivered by each of the Buyers and, assuming this Agreement constitutes the valid and binding obligation of Sellers and Sellers’ Representative, constitutes a valid and binding obligation of each of the Buyers enforceable in accordance with its terms, subject as to enforceability to bankruptcy, insolvency, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

          (b) The execution and delivery of this Agreement by the Buyers does not, and the consummation of the transactions contemplated hereby and compliance with the provisions hereof will not, conflict with, or result in any violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any material obligation or to the loss of a material benefit under, or give rise to a right of purchase under, result in the creation of any Lien upon any of the properties or assets of the Partnership or any of its Subsidiaries under, or otherwise result in a material detriment to the Partnership or any of its Subsidiaries under, any provision of (i) the Organizational Documents of the Partnership (each as amended to date) or any provision of the comparable charter or organizational documents of any of its Subsidiaries, (ii) any loan or credit agreement, note, bond, mortgage, indenture, lease or other agreement, instrument, permit, concession, franchise or license or other Contract applicable to the Partnership or any of its Subsidiaries, (iii) any joint venture or other ownership arrangement or (iv) assuming each Notification and Authorization referred to in Section 5.2 is duly and timely made or obtained, any Law, Regulation or Order applicable to the Partnership or any of its Subsidiaries or any of their respective properties or assets, other than, in the case of clause (ii) or (iii), any such conflicts, violations, defaults, rights, Liens or detriments that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect on the Partnership.

          (c) No Notification to, and no Authorization from, any Governmental Authority is required by or with respect to the Partnership or any of its Subsidiaries in connection with the execution and delivery by the Buyers of this Agreement and the other Transaction Documents to which they are or will be a party or the performance by the Buyers of their respective obligations hereunder or thereunder, except for: (i) such filings and/or notices as may be required under the Securities Act or the Exchange Act; (ii) filings with the Nasdaq; (iii) such filings and approvals as may be required by any applicable state securities, “blue sky” or takeover laws or environmental laws; (iv) any Post-Closing Notifications; and (v) any such

     5.3 SEC Documents. The Partnership has made available to Bear Cub and each Member a true and complete copy of each of the Partnership SEC Documents and exhibits to each of the Partnership SEC Documents. The Partnership SEC Documents constitute each registration statement, prospectus (other than preliminary prospectuses), and other material report and schedule filed by the Partnership with the SEC since December 31, 2005 (other than any registration statement and related prospectus relating to any employee benefit plan) and include all the material reports and schedules (other than preliminary material) that the Partnership was required to file with the SEC since December 31, 2005. As of their respective dates, the Partnership SEC Documents complied as to form in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and the rules and regulations of the SEC thereunder applicable to such Partnership SEC Documents, and none of the Partnership SEC Documents contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of the Partnership included in the Partnership SEC Documents were prepared from the books and records of the Partnership and its subsidiaries, complied as to form in all material respects with the published rules and regulations of the SEC with respect thereto, were prepared in accordance with GAAP applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto or, in the case of the unaudited statements, as permitted by Rule 10.01 of Regulation S-X of the SEC) and fairly present in accordance with applicable requirements of GAAP (subject, in the case of the unaudited statements, to normal, recurring adjustments, none of which is material) the consolidated financial position of the Partnership and its consolidated subsidiaries as of their respective dates and the consolidated results of operations and the consolidated cash flows of the Partnership and its consolidated Subsidiaries for the periods presented therein. Notwithstanding the foregoing statements, the Buyers make no representation or warranty and shall have no liability with respect to any current report on Form 8-K of the Partnership that has been “furnished” rather than “filed” with the SEC.

     5.4 Absence of Certain Changes or Events. Except as disclosed in, or reflected in the financial statements included in, the Partnership SEC Documents, since December 31, 2005, the Partnership has conducted its business only in the ordinary course of business, and there has not been: (a) any material damage, destruction or other casualty loss (whether or not covered by insurance) affecting the business or assets owned or operated by the Partnership and its subsidiaries; or (b) any other transaction, commitment, dispute or other event or condition (financial or otherwise) of any character (whether or not in the ordinary course of business) that, individually or in the aggregate, has resulted in or could reasonably be expected to result in a Material Adverse Effect on the Partnership.

     5.5 Litigation. Except as disclosed in the Partnership SEC Documents, there is no suit, action or proceeding pending, or, to Buyers’ Knowledge, threatened against or affecting the Partnership or any Subsidiary of the Partnership (“Partnership Litigation”), and, to the Buyers’ Knowledge, there are no facts that are likely to give rise to any Partnership Litigation, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect on the Partnership, nor is there any judgment, decree, injunction, rule or order of any

Governmental Authority or arbitrator outstanding against the Partnership or any Subsidiary of the Partnership that could reasonably be expected to result in a Material Adverse Effect on the Partnership.

     5.6 Taxes. From and at all times since its formation, the Partnership has qualified as a partnership for U.S. federal income tax purposes under Section 7704(c) of the Code, and all Tax Returns have been prepared consistently therewith.

     5.7 Broker’s or Finder’s Fees. No investment banker, broker, finder or other Person is entitled to any brokerage or finder’s fee or similar commission in respect of the transactions contemplated by this Agreement or any Transaction Document based in any way on agreements, arrangements or understandings made by or on behalf of Buyers or any of its Affiliates that is, or following the Closing would be, an obligation of Pueblo, Sellers or any of their respective Affiliates.

     5.8 Investment Intent. Buyers are acquiring the Interests for their own account for investment and not with a view to, or for sale in connection with, any distribution thereof, nor with any present intention of distributing or selling the same; and neither Buyer has any present or contemplated agreement, undertaking, arrangement, obligation, indebtedness or commitment providing for the disposition thereof.

               (i) with respect to each individual Claim, the Buyer Indemnitees, collectively, or the Seller Indemnitees, collectively, shall have suffered or incurred Losses with respect to the individual Claim or series of related Claims that arise out of substantially the same facts and circumstances for which recovery is sought in excess of $25,000, in which case the full amount of such Losses shall be recoverable, subject to the limitations imposed by the other provisions of this Section 10.4; provided, however, that this clause (i) shall not apply for purposes of determining whether the Deductible shall have been satisfied; and

          (e) Notwithstanding anything to the contrary in this Agreement:

               (i) For purposes of determining whether a representation or warranty contained herein, other than those set forth in Sections 4.14, 4.19 and 5.3, has been breached for purposes of this Article X and determining the amount of Losses suffered thereby by any Buyer Indemnitee or Seller Indemnitee, as the case may be, each representation and warranty set forth in this Agreement (other than as aforesaid), and any qualification with respect to any such representation or warranty set forth in the Disclosure Letter in the case of representations or warranties by the Members or Bear Cub, shall be read without regard or giving effect to any “material,” “materiality,” “Material Adverse Effect,” and “substantial” qualifications that may be contained in any such representation or warranty; provided, however, that the defined term “Material Contract” and all “material,” “materiality,” “Material Adverse Effect,” and “substantial” qualifications that are contained in any defined term shall be given effect;

          (f) Subject to Section 10.4(h), if a Claim for indemnification is asserted with respect to a breach of a Title Representation:

               (i) each Indemnifying Member shall be severally liable for 50% of all Losses incurred by the Indemnified Party with respect to such breach and the Indemnified Party shall be entitled to recover from, and shall have personal recourse to and against, each Indemnifying Member for 50% of such Loss; and

               (ii) Until the Survival Date, Bear Cub shall be jointly and severally liable with the Indemnifying Members for the full amount of such Loss.

          (g) If a Claim for indemnification is asserted by any Buyer Indemnitee under Section 10.3, the Buyer Indemnitee may, except as set forth in Section 10.4(h), only assert such Claim against, and attempt to recover the Losses with respect to such Claim from, Bear Cub.

          (h) If a Claim for indemnification is asserted by any Buyer Indemnitee under Section 10.3(a) with respect to a breach of a Title Representation, the Buyer Indemnitee must first only assert such Claim against, and attempt to recover the Losses with respect to such Claim

40

from, Bear Cub. If Bear Cub does not satisfy the Losses associated with any such Claim within 30 days following the day that the Claim is first asserted against Bear Cub, the Buyer Indemnitees shall be entitled to assert and pursue any and all rights to indemnification from Bear Cub and, in accordance with Section 10.4(f), the Indemnifying Members;

               (i) Notwithstanding any other provision of this Agreement, except as provided in Section 10.4(f) and Section 10.4(h) the Buyer Indemnitees shall not be entitled to recover Losses from or have any other recourse against any Member relating to any claim arising from this Agreement.

     10.5 Intentionally Omitted.

     10.6 Notice of Asserted Liability; Opportunity to Defend.

          (a) All claims for indemnification hereunder shall be asserted and handled pursuant to this Section 10.6. 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 10.1(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 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 10.1.

          (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

41

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 and the Indemnifying Party shall be responsible for paying for counsel for the Indemnified Party if it is otherwise entitled to indemnification with respect to such matter. If a Proceeding is asserted against both the Indemnifying Party and the Indemnified Party and there are 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 may be effected by the Indemnifying Party without the Indemnified Party’s written consent 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.

          (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 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. Notwithstanding anything to the contrary contained in this Agreement, no Third Person Claim may be settled or otherwise compromised without the prior written consent of the Indemnifying Party.

          (f) The costs and expenses of a Buyer Indemnitee or Seller 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 Buyer Indemnitee or Seller Indemnitee, as the case may be, has the right to control shall be treated as “Losses” for all purposes hereunder.

     10.7 Exclusive Remedy. AS BETWEEN THE SELLER INDEMNITEES AND BEAR CUB AND MEMBERS, ON ONE HAND, AND THE BUYER INDEMNITEES AND THE BUYERS, ON THE OTHER, AFTER CLOSING, OTHER THAN WITH RESPECT TO CLAIMS FOR FRAUD, (A) THE PROVISIONS SET FORTH IN THIS ARTICLE X 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 UNDER THIS AGREEMENT OR WITH RESPECT TO THE TRANSACTIONS CONTEMPLATED HEREBY OTHER THAN AS IS EXPRESSLY PROVIDED IN THIS ARTICLE X.

     10.8 Limitation on Damages. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IN NO EVENT SHALL ANY PARTY BE LIABLE AFTER THE CLOSING TO ANY OTHER PARTY, OR TO ANY INDEMNITEE, UNDER THIS AGREEMENT FOR ANY EXEMPLARY, PUNITIVE, REMOTE, SPECULATIVE, CONSEQUENTIAL, INDIRECT OR SPECIAL DAMAGES, AND NO CLAIM SHALL BE MADE OR AWARDED AGAINST ANY PARTY, FOR ANY SUCH DAMAGES; PROVIDED, HOWEVER, SUBJECT TO THE LIMITATIONS IN SECTION 10.4, THIS SECTION 10.8 SHALL NOT LIMIT THE RIGHT OF THE OR BUYERS TO RECOVER ANY LOSS TO THE EXTENT (A) ACTUALLY SUFFERED, INCURRED OR PAID BY THE BUYERS TO ANY THIRD PARTY OR WITH RESPECT TO ANY THIRD PARTY OBLIGATION OR (B) ARISING OR RESULTING FROM A BREACH OF SECTION 4.14 OR 4.20.

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

     10.10 Disclaimer. WITHOUT DIMINISHING THE REPRESENTATIONS AND WARRANTIES MADE BY BEAR CUB IN ARTICLE IV, BUYERS ACKNOWLEDGE THAT BUYERS HAVE HAD AN OPPORTUNITY TO INSPECT THE ASSETS AND HAVE BEEN ADVISED BY BEAR CUB THAT: (1) THE ASSETS OWNED BY THE PUEBLO COMPANIES HAVE BEEN USED FOR NATURAL GAS, NATURAL GAS LIQUIDS, CONDENSATE OR REFINED PRODUCT OPERATIONS AND PHYSICAL CHANGES IN SUCH ASSETS AND IN THE LANDS BURDENED THEREBY MAY HAVE OCCURRED AS A RESULT OF SUCH USES, AND (2) SUCH ASSETS INCLUDE BURIED PIPELINES AND OTHER EQUIPMENT, THE LOCATIONS OF WHICH MAY NOT BE READILY APPARENT BY A PHYSICAL INSPECTION OF SUCH ASSETS OR THE LANDS BURDENED THEREBY; AND BUYERS ACKNOWLEDGE AND AFFIRM THAT, EXCEPT AS EXPRESSLY REPRESENTED AND WARRANTED BY BEAR CUB IN THIS AGREEMENT, THE ASSETS ARE ACCEPTED AS IS WHERE IS.

EXCEPT AS EXPRESSLY SET OUT IN THIS AGREEMENT, SELLERS MAKE NO REPRESENTATION, WARRANTY OR COVENANT, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE WITH RESPECT TO THE ASSETS, TO THE BUYERS WITH RESPECT TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

          (a) The Party believing a dispute to exist will give the other Parties prompt written notice thereof, setting forth in reasonable detail the facts alleged to give rise to such dispute, any relevant contractual provisions, the nature of any claimed default or breach and a statement of the manner in which such Party believes the dispute should be resolved.

          (b) Within 20 days after receipt of such notice, each Party against whom relief is sought in connection with such dispute will deliver a written response, setting forth in reasonable detail its views of the facts alleged to give rise to such dispute, any relevant contractual provisions, the nature of the claimed default or breach and a statement of the manner in which such Party believes the dispute should be resolved.

          (c) If the Parties do not agree on the manner in which the dispute should be resolved, they will arrange to hold a meeting within 10 days after delivery of the response. Each Party will have in attendance at such meeting a representative with the authority to resolve such dispute. At the meeting (and any adjournments thereof), the Parties will negotiate in an attempt to agree as to whether a dispute exists, the exact nature of the dispute and the manner in which the dispute should be resolved. Any resolution of the dispute will be evidenced by a written agreement setting forth in reasonable detail the actions to be taken by each Party. If no such written agreement is reached within 20 days after the first meeting, each Party shall be entitled to pursue any and all remedies available to it, including pursuing an action in a court of law or equity.

     11.7 Governing Law and Dispute Resolution.

          (a) Governing Law. This Agreement, and all rights and obligations arising hereunder, shall be governed by, enforced in accordance with, and interpreted under, the Laws of the State of Texas, 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 Dallas, Texas, and appropriate courts of appeal therefrom, over any dispute arising out of or relating to this Agreement, the rights and obligations arising hereunder, or any of the transactions contemplated hereby, and each Party hereby irrevocably agrees that all claims in respect of such dispute or proceeding shall be heard and determined in such courts. The Parties hereby irrevocably waive, to the fullest extent permitted by Law, (i) any objection that they may now or hereafter have with respect to venue in such court for any dispute arising out of or relating to this Agreement, the rights and obligations arising hereunder, or any of the transactions contemplated hereby and (ii) 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 11.7(b) by the mailing of a copy thereof in the manner specified by the provisions of Section 11.8.

          (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 resulting in 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.

          (d) Settlement Proceedings. All aspects of any settlement proceedings, including discovery, testimony and other evidence, negotiations and communications pursuant to this Section 11.7, 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.

or at such other address as a Party may designate by written notice to the other Parties in the manner provided in this Section 11.8. 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.

     11.9 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 unreasonably be withheld or delayed. Prior to Closing the Partnership and Bear Cub will consult in advance on the necessity for, and the timing and content of, any communications to be made to the public and, subject to legal

constraints, to the form and content of any application or report to be made to any Governmental Authority that relates to the transactions contemplated by this Agreement.

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

     11.11 No Partnership; Third Party Beneficiaries. Nothing in this Agreement shall be deemed to create a joint venture, partnership, tax partnership, or agency relationship between 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 X shall inure to the benefit of the Buyer Indemnitees and the Seller Indemnitees as provided therein.

     11.12 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.

     11.13 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.

     11.14 Specific Performance. The Parties recognize that, if Sellers should refuse to perform under the provisions of this Agreement, monetary damages alone will not be adequate. The Buyers shall therefore be entitled, in addition to any other remedies that may be available, including money damages, to obtain specific performance of the terms of this Agreement. In the event of any action to enforce this Agreement specifically, Sellers and Sellers’ Representative hereby waives the defense that there is an adequate remedy at law. The parties recognize, however, that, if the Buyers should refuse to perform under the provisions of this Agreement monetary damages will be adequate. Sellers shall therefore be entitled as its sole remedy in lieu of specific performance to recover damages with respect to the failure of the Buyers to comply with their obligations arising under this Agreement.

     11.15 Affiliate Liability. Each of the following is herein referred to as a “Buyer Affiliate”: (i) any direct or indirect holder of the Common Units, Subordinated Units, General Partner Units or other Equity Interests in the Partnership (whether limited or general partners, members, stockholders or otherwise), and (ii) any director, officer, manager, employee, representative or agent of (A) the Partnership or Pueblo Holdings or any Subsidiary of either of them or (B) any Person who directly or indirectly controls the Partnership. Except to the extent that a Buyer Affiliate is an express signatory thereto or an express assignee of the Partnership, or Pueblo Holdings, no Buyer Affiliate shall have any liability or obligation to Sellers of any nature whatsoever in connection with or under this Agreement, any of the Transaction Documents or the transactions contemplated herein or therein, and Sellers on behalf of themselves and each Pueblo Company and Seller Affiliate hereby waive and release all claims of any such liability and obligation. Notwithstanding the foregoing, no Seller shall be deemed an Affiliate of the Partnership.

     11.16 No Waiver of Claims for Fraud. The liability of any Party under Article X 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 11.16 shall be deemed a waiver of any defenses that may be available in respect of actions or claims for fraud, including defenses of statutes of limitations or limitations of damages.

     11.17 No Recovery. No Seller shall be entitled to indemnification or contribution from any Pueblo Company for any Losses that it is obligated to pay pursuant to any Claim brought by a Buyer Indemnitee. Sellers hereby waive and release any and all rights that they may have to assert claims of indemnification or contribution against any Pueblo Company under this Agreement, any other Transaction Document, any other Contract or any provision of their Organizational Documents for any Losses that any Seller is obligated to pay pursuant to any Claim brought by a Buyer Indemnitee.

     11.18 Appointment of Sellers’ Representative.

          (a) If at any time Robert J. Clark (or any successor Sellers’ Representative) dies or becomes disabled or is otherwise unable or refuses to perform his duties as the Sellers’ Representative, the Members shall designate a successor as soon as practicable and shall notify the Partnership in writing of such designation. Upon written notice delivered to the Partnership, the Members may change the identity of the Sellers’ Representative by written consent signed by each Member. In either case, each Member shall execute and deliver a power of attorney substantially in the form of Exhibit H attached hereto appointing such Sellers’ Representative upon the terms and conditions stated therein (including as a result of the resignation by the Sellers’ Representative). If any Member does not deliver a power of attorney, such Sellers’ Representative shall nonetheless have all of the rights, powers and obligations to the same extent of the previous Sellers’ Representative as set forth on Exhibit H hereto.

          (b) By execution of this Agreement, Robert J. Clark has accepted his appointment as Sellers’ Representative and in consideration for Robert J. Clark’s (or any successor Sellers’ Representative) agreement to act as the Sellers’ Representative.
