Closing Over Breaches or Unsatisfied Conditions. If Sellers or Purchaser elect to proceed with the Closing with Knowledge of any failure of any condition to be satisfied in its favor, the condition that is unsatisfied at the Closing Date and the underlying breach of the representation, warranty or covenant which resulted in the failure of the condition to be satisfied 21 (if applicable) will be deemed waived by such Party and such Party will be deemed to fully release and forever discharge the other Party on account of any and all claims, demands or charges, known or unknown, with respect to the same. 6.8. Imbalances. Schedule 6.8 sets forth the actual amounts of the Imbalance Payables and the Imbalance Receivables as of the date set forth in such schedule. Sellers agree to cause the Partnership to use commercially reasonable efforts to minimize the amount of the Imbalance Payables and the Imbalance Receivables outstanding as of the Effective Time. Sellers will make a good faith estimate of the Imbalance Payables and the Imbalance Receivables as of the date five Business Days before Closing and will update Schedule 6.8 to reflect such estimate. The net amount of the Imbalance Payables and the Imbalance Receivables set forth in the final Schedule 6.8 will be cashed out as between Sellers and Purchaser based upon the formula set forth in Schedule 6.8 and identified as the "Imbalance Cash Out Formula" (the "IMBALANCE VALUE"). The Purchase Price will be adjusted by the Imbalance Value in accordance with Section 2.4. 6.9. Further Actions. Each of the Purchaser, the Sellers and the Partnership shall execute and deliver such instruments and take such other actions as may reasonably be required to (a) carry out the intent of this Agreement and (b) consummate the transactions contemplated hereby. In addition, (i) at or prior to the Closing, Sellers shall terminate any authorizations and powers of attorney regarding the Partnership or its business in favor of any Person other than a Transferred Employee and shall cause the Partnership to terminate (and to obtain mutual releases with respect to any liabilities and obligations under) any Contracts with Sellers or any of their respective Affiliates other than items 1 and 2 on Schedule 6.9 and (ii) effective as of the Closing, Sellers shall cause the Partnership to have no right or responsibility with respect to any of the types of obligations described in Section 4.17. 6.10. Access to Information; Cooperation. (a) From the date hereof until the Closing Date, Sellers will (i) give, and will cause the Partnership to give, Purchaser, its counsel, financial advisors, auditors and other authorized representatives reasonable access during normal business hours to the offices, properties, assets, books, records and other documents of the Partnership and to the books and records of the Sellers relating to the Partnership (provided, however, that the Purchaser shall not be entitled to conduct any environmental testing or sampling on or at any properties or Facilities of the Partnership without the prior written consent of the Sellers (which consent may be withheld in Sellers' sole discretion), (ii) furnish, and will cause the Partnership to furnish, to Purchaser, its counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information prepared by Sellers or the Partnership in the ordinary course of business and relating to the Partnership as such person may reasonably request, and (iii) permit Purchaser to make such inquiries of such persons having business relationships with the Partnership (including suppliers, licenses and customers) as Purchaser shall reasonably determine (provided that such inquiries are coordinated with Sellers, and Sellers are given the opportunity to have a representative participate with the Purchaser), and Sellers will cooperate fully, and will cause the Partnership to cooperate fully, with Purchaser in connection therewith. Any investigation pursuant to this Section 6.10 shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of Sellers or the Partnership. No investigation by Purchaser or other information received by Purchaser shall 22 operate as a waiver or otherwise affect any representation, warranty, covenant or agreement given or made by Sellers or the Partnership hereunder. (b) Promptly following Closing, Sellers will provide representatives of Purchaser, at no cost or expense to Sellers, with assistance and access to data during normal business hours, including accounting and other books and records of the Partnership and Sellers (to the extent related to the Partnership) and appropriate personnel of Sellers and Sellers' Affiliates, reasonably required by Purchaser to enable Purchaser to prepare for the Partnership: (i) an audited balance sheet and related statements of income and cash flows for each of its three most recent fiscal years, or (ii) other financial statements. Sellers agree to authorize Purchaser's independent auditors access to the Partnership's working papers. However, it is expressly agreed that no Purchaser representative, including the independent auditors engaged by Purchaser as contemplated by this Section 6.10(b), will have access to any unpublished accounting information or working papers other than those of the Partnership. 6.11. Notices of Certain Events. Each Party shall promptly notify the other Party of: (a) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement; (b) any notice or other communication from any Governmental Entity in connection with the transactions contemplated by this Agreement; (c) any written notice or threat of the cancellation of any insurance policy maintained on behalf of the Partnership or any denial of coverage or reservation of rights notice received with respect to any claim for which insurance is or may be available; (d) any actions, suits, claims, investigations or proceedings commenced, or, to either Party's Knowledge, threatened against, or relating to or involving or otherwise affecting Sellers, Purchaser or the Partnership that, if pending on the date of this Agreement, would have been required to have been disclosed under this Agreement; and (e) any damage, destruction, loss or casualty (whether or not covered by insurance) or any other event that would have a material effect on the business of the Partnership. 6.12. Casualty Loss. In the event any assets of the Partnership are lost, damaged or destroyed by fire, flood, storm or other casualty or taken in condemnation prior to the Closing Date, and the monetary value of such loss, damage, destruction or taking ("CASUALTY LOSS") is less than $2 million (without regard to insurance coverage), then the Casualty Loss will not affect Closing or the Purchase Price, and Purchaser will be entitled to receive (and Sellers will assign any of their respective rights to) any insurance proceeds paid or payable with respect to the Casualty Loss. If the Casualty Loss is $2 million or more (without regard to insurance coverage), the Purchase Price shall be reduced by an amount equal to the amount of such Casualty Loss, and the Partnership shall assign to Sellers if necessary and Sellers shall be entitled to receive or retain any insurance and/or condemnation payable in connection therewith.. In addition to the foregoing right, if the sum of the Casualty Loss and the net present value of any 23 lost net revenues that is reasonably expected to be suffered by the Partnership from and after the Closing as a result of such Casualty Loss exceeds $10 million, either Party may terminate this Agreement pursuant to Section 9.1. 6.13. Insurance. Effective at Closing, Sellers may terminate or cause the Partnership to terminate all insurance coverage on the Partnership or its assets (the "PARTNERSHIP INSURANCE POLICIES"), and Purchaser is solely responsible to provide any insurance coverage from and after the Closing Date. Any premiums returned to Sellers or the Partnership related to periods after Closing will be paid to Purchaser. Nothing in this Section will terminate coverage with respect to any claims made under the Partnership Insurance Policies before Closing. 6.14. Excluded Assets. Before Closing, Sellers shall cause the Partnership to assign all right, title and interest in and to the assets and properties listed on Schedule 6.14 to this Agreement (the "EXCLUDED ASSETS") to Sellers or one of Sellers' Affiliates. Notwithstanding anything to the contrary contained in this Agreement, the transactions contemplated by this Agreement exclude the Excluded Assets. 6.15. Books and Records. At Closing, Sellers shall deliver to Purchaser or cause to be present at the Facilities, originals of the Partnership's partnership agreement and any company records related to the Partnership. Within a reasonable period (not to exceed 90 days) after the Closing Date, Sellers shall deliver to Purchaser all originals of any other books, logs, records, documents and data of the Partnership or the Sellers and its Affiliates, to the extent relating solely or primarily to the Partnership or the Facilities and not delivered pursuant to the preceding sentence, as well as copies of all books, logs, records, documents and data of the Sellers and its Affiliates that relate to the Partnership or the Facilities and do not relate solely to the Sellers or such Affiliates (any information not relating to the Partnership or the Facilities may be redacted), as applicable. 6.16. Title Review. (a) Within the Defect Examination Period (as defined below), Purchaser may conduct a review of the Partnership's title to the real property interests described in Schedule 4.21 or used in the conduct of the Partnership's business (the "REAL PROPERTY INTERESTS"), and assert "Title Defects" as defined below against Sellers, in accordance with the procedures set forth in this Section 6.16. As used in this Section 6.16, "Title Defect" means any title gap, Lien (other than a Permitted Lien) or failure to grant the rights currently used by the Partnership, in, upon or against the Partnership's title to the Real Property Interests that would cause the Partnership not to have good and marketable title to such Real Property Interests or not to be able to use such Real Property Interests for the Partnership's business as currently conducted. The foregoing notwithstanding, any defect in title, title gap, Lien, or failure to grant the rights currently used by the Partnership, with respect to an easement or right-of-way, will not constitute a Title Defect if the defect, title gap, Lien or failure to grant the rights currently used by the Partnership does not and is not reasonably likely to prohibit or interfere with the use thereof in accordance with past practice. (b) Prior to the expiration of the Defect Examination Period, Purchaser shall furnish to Sellers written notice(s) (each, a "DEFECT NOTICE") specifying in reasonable detail each 24 matter which, in Purchaser's opinion, constitutes a Title Defect (including any and all reasonable supporting documentation), and which Purchaser wishes to assert as a Title Defect hereunder, together with the costs that Purchaser, in good faith, estimates to be the costs necessary to cure or remediate the described Title Defects (each a "DEFECT AMOUNT"). The "DEFECT EXAMINATION PERIOD" shall mean the period commencing on the date hereof and ending 40 days after such date or 2 Business Days before Closing, if earlier. Any Title Defects not asserted by Purchaser on or before the expiration of the Defect Examination Period in accordance with this Section 6.16 shall be deemed conclusively to be waived. Sellers shall have no liability for any Defect Amount until and unless the sum of all Defect Amounts exceeds $250,000 (the "TITLE THRESHOLD") and then only to the extent that such sum exceeds the Title Threshold. (c) If the sum of all Defect Amounts asserted by Purchaser exceeds $5,000,000, Sellers may terminate this Agreement pursuant to Section 9.1. If the sum of all Defect Amounts asserted by Purchaser is good faith exceeds $10,000,000, Purchaser may terminate this Agreement pursuant to Article 9. (d) Sellers shall provide a written response to Purchaser within 15 days following the expiration of the Defect Examination Period stating, with respect to each Title Defect asserted in the Defect Notice(s), whether or not Sellers agree: (a) that the alleged Title Defect constitutes a Title Defect under the terms of this Agreement; and (b) that Purchaser's estimate of the Defect Amount attributable to each Title Defect asserted by Purchaser is acceptable to Sellers (the "RESPONSE NOTICE"). If Sellers disagree with Purchaser's assertion of the existence of a Title Defect or the Defect Amount with respect thereto, Sellers' Response Notice shall also specify in reasonable detail Sellers' grounds for such disagreement, the Defect Amount estimated in good faith by Sellers therefor, or both, as the case may be. If Sellers do not include in their Response Notice an objection to a Title Defect or to the Defect Amount, or if Sellers' Response Notice agrees that the alleged Title Defect constitutes a Title Defect under the terms of this Agreement and that Purchaser's estimate of the Defect Amount is acceptable, then that Defect Amount shall be the amount taken into consideration under this Section 6.16, regardless of the costs that Purchaser in fact incurs in curing that Title Defect. Sellers and Purchaser will attempt in good faith to resolve any disagreements with respect to the matters set forth in Purchaser's Defect Notice(s) and Sellers' Response Notice within 30 days following Purchaser's receipt of Sellers' Response Notice. If Sellers and Purchaser are unable, within such 30 day period, to agree in writing as to the existence or value, as applicable, of any Title Defect, the Parties agree to submit the dispute to an oil and gas title attorney licensed to practice law in the state of Oklahoma and mutually agreeable to the Parties (or if the Parties do not agree, as appointed by a state district judge in Beckham County, Oklahoma)(herein, the "INDEPENDENT ATTORNEY"). The decision of the Independent Attorney with respect to the disputed matters shall be final and binding on the Parties. The Parties will direct the Independent Attorney to render its decision with respect to such matters within 15 days after the dispute is submitted, or such reasonably longer period as the Independent Attorney requires in its reasonable discretion. Sellers and Purchaser will each promptly provide all information and documents within their respective possession that the Independent Attorney requests in order to make its decision with respect to the disputed matters. The fees of the Independent Attorney will be borne equally by Sellers, on the one hand, and Purchaser, on the other hand. 25 (e) With respect to each Title Defect, Sellers may, at their election, either remit to Purchaser the Defect Amount (after satisfaction of the Title Threshold) or at Sellers' sole cost and expense, and subject to the prior consent of Purchaser (such consent not to be unreasonably withheld), cure within the Cure Period (as hereinafter defined) such Title Defect asserted by Purchaser for which Sellers are liable hereunder. The "Cure Period" shall mean the period of time commencing on the expiration of the Defect Examination Period and ending 90 days after such date. Immediately following the expiration of the Cure Period, Sellers shall provide Purchaser with written evidence of any curative actions which, in Sellers' determination, cure the Title Defect. On or before the expiration of 15 days following Purchaser's receipt of such notice, Purchaser shall provide to Sellers in writing a list of those Title Defects asserted by Purchaser which Sellers claim to have cured pursuant to this Section, and which Purchaser determines not to have been cured. For a period of 30 days after Sellers' receipt of Purchaser's notice of uncured Title Defects, Sellers and Purchaser shall attempt in good faith to resolve disputes as to such items by agreement. In the event that the dispute concerning any uncured Title Defect is not resolved within this 30 day period, and the Parties are unable to resolve all disputes concerning the existence of Title Defects or Defect Amounts within this 30 day period, then Sellers shall remit to Purchaser the Defect Amount for such uncured Title Defect (after satisfaction of the Title Threshold). (f) The existence of any dispute under this Section 6.16 will not delay Closing, and the resolution of disputes regarding any Title Defect asserted by Purchaser in conformance with this Section 6.16 will be resolved after the Closing as herein provided.

Indemnification by Sellers. Sellers (jointly and severally) agree to indemnify and hold Purchaser, its Affiliates and their respective directors, officers, employees, contractors, agents and other representatives (each such Person being herein called a "PURCHASER INDEMNIFIED PARTY," and all such Persons being collectively herein called the "PURCHASER INDEMNIFIED PARTIES") harmless against any liability, loss, damage, action, award, suit, proceeding, hearing, investigation, charge, complaint, demand, injunction, judgment, order, decree, ruling, taxes or liens, claim, cost, or expense (including penalties and interest and reasonable legal fees and costs) (individually or collectively, "LOSSES") that such Purchaser Indemnified Party incurs to the extent arising out of or resulting from any of the following: (i) the failure of any of the representations and warranties made by Sellers in Article 4 of this Agreement or in any certificate delivered at the Closing (other than with respect to the first sentence of Section 4.6) to be true and correct as of the date made (provided, however, that with respect to any claim for indemnity brought after Closing for purposes of determining whether a breach of such representations and warranties has occurred and the amount of Losses incurred, any limitation or qualification as to materiality or Material Adverse Effect set forth in such representation and warranty shall be disregarded); (ii) the failure of Sellers to perform any of the covenants and agreements contained herein; (iii) as a result of the Partnership being a part of a "single employer" within the meaning of Section 4001 of ERISA, or would otherwise have any liability of any Benefit Plan of Sellers or their Affiliates; (iv) for any Tax of Sellers or any Tax of the Partnership arising as a result of the Partnership being a part of a consolidated group under Treasury Regulation Section 1.1-502 (or any similar provision of state or local law); (v) any Excluded Asset (vi) the breach of the representation and warranty of the Sellers made in the first sentence of Section 4.6 or in any certificate delivered at the Closing with respect to such representation; or (vii) relating to or arising out of the matters disclosed on Schedule 8.1. 8.2. Indemnification by Purchaser. Purchaser agrees to indemnify and hold each Seller, its Affiliates and their respective directors, officers, employees, contractors, agents and other representatives (each such Person being herein called a "SELLER INDEMNIFIED PARTY," and all such Persons being collectively herein called the "SELLER INDEMNIFIED PARTIES") harmless against any Losses that such Seller Indemnified Party incurs to the extent arising out of or resulting from any of the following: (i) the failure of any of the representations and warranties made by Purchaser in Article 5 of this Agreement or in any certificate delivered at the Closing to be true and correct as of the date made; (ii) the failure of Purchaser to perform any of the covenants and agreements contained herein; or (iii) except as otherwise provided in Section 3.4 or 8.1 hereof, all obligations and liabilities of whatever kind and nature, primary or secondary, direct or indirect, absolute or contingent, known or unknown, whether or not accrued, relating to the business of the Partnership, the assets of the Partnership or the ownership of the Interests, including any such obligations or liabilities contained in any contract or any license, lease, contract, commitment, agreement or instrument binding the Partnership and whether arising before or after the Closing Date. 8.3. Indemnification Procedures. The Party entitled to receive indemnification under this Agreement (the "INDEMNITEE"), shall promptly give to the other party (the "INDEMNIFYING PARTY") written notice of any matter that such party has determined has given or could give rise 28 to a right of indemnification under this Agreement. If an Indemnitee receives notice of any claim by a third party which is or may be subject to indemnification (a "THIRD PARTY CLAIM"), Indemnitee shall give Indemnifying Party prompt written notice of such Third Party Claim and Indemnifying Party shall, at Indemnifying Party's expense, defend against such Third Party Claim. If, however, Indemnifying Party fails to acknowledge in writing its obligation to indemnify Indemnitee hereunder against all Losses that may result from such Third Party Claim, then Indemnitee, at Indemnifying Party's expense, shall be entitled, at its option, to assume the defense of such Third Party Claim through counsel of its choice. In any event, Indemnitee shall have the right to employ Indemnitee's own counsel and participate in the defense of the case, but the fees and expenses of Indemnitee's counsel shall be at the expense of Indemnitee, unless (a) the employment of Indemnitee's counsel at the expense of Indemnifying Party shall have been authorized in writing by Indemnifying Party in connection with the defense of the action, suit, or proceeding or (b) Indemnitee shall have reasonably concluded that Indemnitee's interests could only be adequately protected by Indemnitee's direct participation in or defense of the action, suit or proceeding. In any case described in clause (b) of the preceding sentence, Indemnifying Party shall not have the right to direct the defense of the action, suit or proceeding on behalf of Indemnitee, but the fees and expenses incurred in connection therewith shall be borne by Indemnifying Party. No such Third Party Claim may be settled by Indemnifying Party without the written consent of Indemnitee, unless the settlement involves only the payment of money by Indemnifying Party and such payment does not affect the goodwill of Indemnitee and/or the Partnership. Similarly, no Third Party Claim which is being defended in good faith by Indemnifying Party shall be settled by Indemnitee without the written consent of Indemnifying Party. 8.4. Conduct of Defense. Any Party granted the right to direct the defense of a claim pursuant to this Section shall: (a) keep the other Party to this Agreement fully informed of the action, suit, or proceeding at all stages of the matter, whether or not represented; (b) promptly submit to the other Party copies of all pleadings, responsive pleadings, motions, and other similar legal documents and papers received in connection with the action, suit or proceeding; (c) permit the other Party to this Agreement and its counsel, to the extent practicable, to confer on the conduct of the defense of the action, suit, or proceeding; and (d) to the extent practicable, permit the other Party to this Agreement and its counsel an opportunity to review all legal papers to be submitted before the submission. Subject to an appropriate confidentiality agreement, the Party shall make available to each other and each other's counsel and accountants all of the books and records relating to the action, suit, or proceeding, and each Party shall render to the other any assistance as may be reasonably required in order to insure the proper and adequate defense of the action, suit, or proceeding. 8.5. Survival of Representations, Warranties and Indemnity Obligations. The Parties' representations and warranties contained in this Agreement will survive Closing for a period of one year after the Closing Date (other than the representations and warranties under (i) Section 4.19, which will survive Closing for a period of two years after the Closing Date, (ii) Sections 4.2, 4.6 and 5.2, which will survive indefinitely and without limitation, and (iii) Sections 4.8, 4.9, 4.20(c) and 4.20(d), which will survive until 30 days after the expiration of the statute of limitations applicable to the matters covered thereby) and will then terminate and be of no further force or effect. The expiration or termination of any representation or warranty does not affect the obligations under this Article 8 if the Party seeking indemnification provides proper 29 notice of the claim or event for which indemnification is sought prior to such expiration or termination. Neither Party has any liability to indemnify, defend or hold harmless the other Party with respect to a breach of a representation or warranty unless proper notice of a claim for such indemnification or defense is received prior to the expiration or termination of the applicable representation or warranty. 8.6. Exclusivity of Remedies. The Parties acknowledge that the sole and exclusive remedy with respect to the subject matter of this Agreement is the right to indemnification according to the provisions set forth in this Article 8. In no event will either Party be responsible for lost profits, punitive damages, consequential damages or any other remedy otherwise available at law or in equity. 8.7. Liability Cap. (a) EXCEPT AS PROVIDED IN SECTION 8.7(B), (I) NO CLAIM FOR INDEMNIFICATION MAY BE MADE UNDER SECTION 8.1(I) (WHETHER MADE UNDER ARTICLE 4 OR ANY CERTIFICATE DELIVERED AT CLOSING) UNLESS AND UNTIL THE AGGREGATE AMOUNT OF LOSSES THAT MAY BE CLAIMED THEREUNDER EXCEEDS $5,000,000, AND THE INDEMNIFYING PARTY SHALL BE LIABLE UNDER SECTION 8.1 ONLY TO THE EXTENT SUCH LOSSES SUFFERED BY THE INDEMNIFIED PARTY EXCEED $5,000,000 IN THE AGGREGATE; (II) NO LOSS WHICH INVOLVES LESS THAN $25,000 SHALL BE INCLUDED IN DETERMINING WHETHER THE AMOUNT OF SUCH INDEMNIFICATION EXCEEDS THE DEDUCTIBLE AMOUNT OF $5,000,000; AND (III) IN NO EVENT SHALL SELLERS' LIABILITY FOR ANY LOSSES UNDER SECTION 8.1(I) EXCEED $40,000,000. (b) The deductible set forth in Section 8.7(a)(I) shall not apply to breaches of any representations and warranties (whether made under Article 4 or in any certificate delivered at Closing) of Sellers under Sections 4.2, 4.4, 4.6, 4.8, 4.20(c) and 4.20(d). (c) IN NO EVENT SHALL PURCHASER'S LIABILITY FOR ANY LOSSES UNDER SECTION 8.2(I) AND 8.2(III) EXCEED $40,000,000. 8.8. Claim Reimbursement and Reduction. Any claim for Losses shall be reduced to the extent of any third party insurance or condemnation payment actually received by the Indemnified Party. ARTICLE 9 TERMINATION 9.1. Rights to Terminate. To the extent set forth in Section 9.2 of this Agreement, this Agreement may be terminated as follows: (a) By mutual written consent of Sellers and Purchaser, this Agreement may be terminated at any time prior to Closing. 30 (b) Either Sellers or Purchaser may terminate this Agreement if a material default or breach of any provision of this Agreement has been committed by the other Party and such material default or breach has not been cured or waived by the date thirty (30) days after receipt by the other Party of written notice from the terminating Party specifying with particularity such breach or default. Such cure period may extend the Automatic Termination Date as defined in (c) below by a maximum of 10 days. (c) This Agreement shall terminate automatically if the Closing has not occurred by 5:00 p.m. Central Standard Time on the date that is 60 days after the execution of this Agreement (the "AUTOMATIC TERMINATION DATE"). (d) Either Party may terminate this Agreement as provided in Section 6.12 or in Section 6.l6. 9.2. Effect of Termination. If there has been a termination pursuant to Section 9.1, then this Agreement shall be deemed terminated, and all further obligations of the Parties hereunder shall terminate, except that the obligations set forth in Articles 8 and 10 shall survive. In the event of such termination of this Agreement, there will be no liability for damages on the part of a Party to another under and by reason of this Agreement or the transactions contemplated hereby except as set forth in Article 8, and except for intentionally fraudulent acts by a Party, the remedies for which will not be limited by the provisions of this Agreement. The foregoing provisions will not, however, limit or restrict the availability of injunctive or other equitable relief to the extent that the same would otherwise be available to a Party hereunder. ARTICLE 10 MISCELLANEOUS 10.1. Assignment. Neither Party may assign, delegate, sub-contract or otherwise transfer this Agreement or any of its rights or obligations without the other Party's prior written consent; provided, however, that Purchaser shall have the right to designate one or more Affiliates to take title to the Interests, but in such event, Purchaser shall remain liable for all of its obligations hereunder. 10.2. Notices. Any notice or other communication required to be given hereunder by either party shall be deemed duly given (i) when personally delivered to the other party, or (ii) three (3) Business Days after mailing if mailed by certified mail return receipt requested, postage prepaid, addressed to the other party at the address specified below or to such address as either party may designate by giving written notice to the other.

(a) All information disclosed in connection with the negotiation and performance of this Agreement other than, with respect to the Purchaser, information regarding the Partnership from and after the Closing is "CONFIDENTIAL INFORMATION." Purchaser and Sellers: (i) shall not disclose any Confidential Information by any means whatsoever to anyone other than an officer, director, partner, or employee of, or counsel or accountant for, Purchaser or Sellers (collectively, "PERMITTED RECIPIENT"), (ii) may disclose the Confidential Information only to a Permitted Recipient and only as provided in this Section, and (iii) shall protect the confidentiality of the Confidential Information in accordance with this Agreement. The Confidential Information is proprietary and commercially sensitive and may constitute a trade secret, and disclosure to the general public could cause harm to one or both Parties. (b) A Party may disclose Confidential Information only to its Permitted Recipients who have a bona fide need to have such information in order to perform obligations or exercise rights of a Party under this Agreement, but such disclosure may be made only after a Permitted Recipient has been provided with a copy of this Agreement and has agreed (which, consistent with but not as a limitation on Section 10.8, must be in writing) to be bound by the terms hereof. (c) Each Party is responsible for: (i) ensuring compliance by its Permitted Recipients with the confidentiality provisions of this Agreement, and (ii) any unauthorized disclosure by its Permitted Recipients. 10.8. Exceptions to Confidentiality Obligations. (a) The confidentiality obligations and restrictions of Section 10.7 do not apply to a disclosure to a Governmental Entity, to the public, or in judicial, administrative, or governmental proceedings if required by law, rule, governmental order, or requirement of any stock exchange or securities regulatory authority; provided however, that prior to making any such disclosure, it must notify the other Party, and such notice must specify and include: (i) the date on which it intends to make such disclosure, and (ii) the text of the proposed announcement or other disclosure; (b) The confidentiality obligations of this Agreement do not apply to information that: (i) at the time of disclosure was in the public domain through reasons other than by: (A) a breach by the other Party of this Agreement, or (B) action or failure to act on the part of the other Party; or 33 (ii) at the time of disclosure by the disclosing Party was lawfully acquired by the other Party from a third party source, provided that such source was not at the time bound by a confidentiality or similar agreement prohibiting the disclosure thereof. (c) The Party asserting that information is not subject to the confidentiality obligations of this Agreement has the burden of proof of substantiating that assertion. 10.9. Governing Law And Jurisdiction. This Agreement will be governed by and construed in accordance with the laws of the State of Texas, without regard to principles of conflicts of laws. Each Party hereby irrevocably and unconditionally submits to the exclusive jurisdiction of the competent courts in the city of Dallas, Texas, thereby expressly waiving any other jurisdiction to which they may be entitled by reason of their present or future domicile or otherwise. THE PARTIES HEREBY WAIVE ANY AND ALL RIGHTS TO DEMAND A TRIAL BY JURY. 10.10. Further Assurances. Purchaser and Sellers agree to execute all instruments and documents, and to take all actions that are reasonably necessary to effect the transactions contemplated by this Agreement. 10.11. No Third Party Beneficiary. Nothing expressed or referred to in this Agreement will be construed to give any Person other than the Parties to this Agreement any legal or equitable right, remedy or claim under or with respect to this Agreement, or any provision of this Agreement. 10.12. Waiver. The delay or failure of a Party to exercise any right or to insist on performance of any obligations is not a waiver of that right or obligation, or any similar right or obligation. Waivers are only effective in writing. 10.13. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement will continue in full force and effect and will in no way be affected, impaired or invalidated. 10.14. Like-Kind Exchange. So long as it does not delay the Closing and Sellers pay the transaction costs for such exchange, Sellers will have the right at any time prior to Closing to assign all or a portion of its rights (but not its obligations) under this Agreement to a qualified intermediary in order to accomplish the transactions contemplated by this Agreement in a manner that would comply, either in whole or in part, with the requirements of a like-kind exchange pursuant to Section 1031 of the Code. If Sellers assign their rights under this Agreement for this purpose, Sellers shall provide Purchaser with prior written notice and Purchaser agrees that, if so requested by Sellers, it will: (a) provide a written consent to Sellers' assignment of its rights in this Agreement for the sole purpose herein described, and (b) pay the Purchase Price into a qualified escrow or qualified trust account at Closing as directed in writing by Sellers. Any assignment of this Agreement to a qualified intermediary will not release Sellers from any of their liabilities or obligations to Purchaser under this Agreement. Sellers will be solely responsible to designate and obtain exchange property and to otherwise comply with 34 Section 1031 of the Code. The rights of the Parties will not be affected by any determination that the transaction does not qualify as a like-kind exchange. 10.15. Release of Information. The Parties shall cooperate with each other in releasing information concerning this Agreement and the transactions contemplated hereby. No press releases or other public announcements concerning the transactions contemplated by this Agreement shall be made by any Party without prior consultation with, and agreement of, the other Parties, except for any legally required communication by any Party and then only with prior consultation and as much advance notice as is practicable under the circumstances requiring any announcement, together with copies of all drafts of the proposed text. In no event shall Sellers release or disclose any information about the performance of the Partnership or its business with respect to any period before or after the Closing, except for any legally required communication by any Party and then only with prior consultation and as much advance notice as is practicable under the circumstances requiring any announcement, together with copies of all drafts of the proposed text.

In 2004, the Partnership voluntarily disclosed a potential non-compliance situation to the Oklahoma Department of Environmental Quality. The potential non-compliance involved the quantification of potential emissions from flashing of liquid hydrocarbons from depressuring operations at natural gas compressor stations and plants. The affected compressor stations are: (i) County Line Compressor Station; (ii) Big Mac Compressor Station; (iii) Dill City Compressor Station; (iv) Elk City Compressor Station; (v) Mayfield Compressor Station; and (vi) Merrit Compressor Station. The affected sites will require renewal of their operating permits. Schedule 4.16 SCHEDULE 4.17 HEDGING [GRAPHIC APPEARS HERE] Schedule 4.17 SCHEDULE 4.19 ENVIRONMENTAL MATTERS 1. In 2001, soil and ground water hydrocarbon contamination were found to exist at the Merrit Compressor Station located approximately six miles southwest of Elk City, in Beckham County, Oklahoma. The contamination resulted from historical overfills of tanks located on the site. Microbes were injected into the subsoil strata containing groundwater and monitoring wells were drilled to assess the progress of remediation. Subsequent testing of groundwater showed successful remediation of hydrocarbon contamination to levels below the Oklahoma closure criteria. Bio-remediation of contaminated soil was begun and has continued for the past several years. Recent tests of soil show successful remediation of the soil contamination and the receipt of a State of Oklahoma Closure Letter is expected shortly.
