ARTICLE III

PREFERENTIAL RIGHTS AND CONSENTS TO ASSIGNMENT

3.1 Allocated Values.

3.1.1 Buyer’s good faith allocation of the value of the Properties is set forth in Exhibits “A-1” through “A-3” (“Good Faith Allocation”), and shall be used, if necessary, for purposes of Sections 3.2, 3.3 and 5.2.

3.1.2 On or before the Closing Date, Buyer and Seller will use commercially reasonable efforts agree upon an allocation of the unadjusted Purchase Price among the Properties in compliance with the principles of Section 1060 of the Code, and the Treasury Regulations thereunder. If Seller and Buyer agree to such allocation, Seller and Buyer agree (1) that such allocation shall be used by Seller and Buyer as the basis for reporting asset values and other items for purposes of all federal, state, and local Tax Returns, including without limitation Internal Revenue Service Form 8594, (2) that neither Seller nor Buyer or any of their respective Affiliates or direct or indirect owners will take a position on any Tax Return, or before any Governmental Authority in connection with the examination of a Tax Return or in any Tax Proceeding that is in any manner inconsistent with such allocation, except as required by applicable Law or with the written consent of the other Party, and (3) Buyer and Seller agree that each shall furnish the other a copy of Form 8594 (Asset Acquisition Statement under Section 1060) proposed to be filed with the Internal Revenue Service by such Party or any Affiliate thereof thirty (30) days prior to such filing.

3.2 Preferential Rights to Purchase.

3.2.1 The Parties agree that those preferential purchase rights set forth in Schedule 3.2 that are currently attributable to the holders identified on such schedule with respect to such preferential purchase rights may be triggered by the transactions contemplated by this Agreement (collectively, the “Applicable Preferential Rights”). For each Property subject to any Applicable Preferential Right, except any Applicable Preferential Right held by Buyer or its Affiliates, Seller shall (i) provide such notice to the applicable Third Party as may be required using the applicable Good Faith Allocation and the form of Preferential Right Notice Letter attached hereto as Exhibit “G”, or as

HOUSTON 1139976v.13

otherwise mutually agreed, and (ii) comply in all other respects with the agreement under which the Applicable Preferential Right arises. If, prior to Closing, the holder of an Applicable Preferential Right notifies Seller that it elects to exercise its Applicable Preferential Right (in accordance with and determined by the agreement under which such Applicable Preferential Right arises), the Properties subject to such exercised Applicable Preferential Right shall be excluded from this Agreement and the Purchase Price shall be reduced by the value allocated to such Property in Exhibits “A-1”, “A-2”, or “A-3”. Buyer remains obligated to purchase the remainder of the Properties that are not affected by exercised Applicable Preferential Rights. Upon consummation of the sale of any Properties to the holder of such Applicable Preferential Right, any such Properties shall be deemed for all purposes to constitute Excluded Properties.

3.2.2 If on the Closing Date, any Applicable Preferential Right has not been waived in writing by the holder thereof or the time for such holder to exercise such Applicable Preferential Right has not expired, then (subject to Sections 15.2, 15.3 and 17.1) the Closing with respect to the Properties to which such Applicable Preferential Right applies shall proceed upon the mutual agreement of Seller and Buyer, so long as Seller’s notification to the holder of such Applicable Preferential Right was given at least thirty (30) Days prior to such Closing Date.

3.2.3 If the Parties do not reach a mutual agreement as contemplated in the prior paragraph, then the applicable Properties shall be deemed Excluded Properties and the Closing shall otherwise proceed. Thereafter, Seller shall promptly notify Buyer if the holder of the Applicable Preferential Right does not exercise such right prior to the expiration of such right, then within ten (10) Business Days after Buyer’s receipt of such notice, the Parties shall conduct a second closing whereby Seller shall sell, assign and convey to Buyer, and Buyer shall purchase and accept from Seller, such Property pursuant to the terms of this Agreement and for the value allocated to such Properties in Exhibits “A-1”, “A-2” or “A-3” (except “Closing Date” with respect to any such Property shall mean the date of assignment of such Property from Seller to Buyer), subject to any purchase price adjustments consistent with this Agreement. If for any reason the purchase and sale of the Properties covered by the Applicable Preferential Rights which have been exercised by the holder thereof are not or cannot be consummated with the holder of the Applicable Preferential Rights in accordance with the agreement under which the Applicable Preferential Right arises, or the holder of the Applicable Preferential Right is unable to satisfy the conditions to closing contained therein, Seller shall promptly notify Buyer and, if the Closing has not yet occurred, the affected Property shall be included in the Closing or, if the Closing has previously occurred, then within ten (10) Business Days after Buyer’s receipt of such notice, the Parties shall conduct an additional closing whereby Seller shall sell, assign and convey to Buyer, and Buyer shall purchase and accept from Seller, such Property pursuant to the terms of this Agreement and for the value allocated to such Properties in Exhibits “A-1”, “A-2” or “A-3” (except “Closing Date” with respect to any such Property shall mean the date of assignment of such Property from Seller to Buyer), subject to any Purchase Price adjustments consistent with this Agreement.

HOUSTON 1139976v.13

3.2.4 If (i) the holder of an Applicable Preferential Right validly exercises its Applicable Preferential Right after the Closing or (ii) the Parties inadvertently close on a Property subject to a preferential purchase right that is not listed on Schedule 3.2 (a “PPR”), either without having provided the required notification to the holder of such Applicable Preferential Right or PPR (“Pref Holder”) or without such Pref Holder having waived such Applicable Preferential Right or PPR or the time for such Pref Holder to exercise such Applicable Preferential Right or PPR having expired, and (ii) after the closing on such Property, the Pref Holder elects to exercise, then Buyer shall convey such Property directly to the Pref Holder, and Buyer shall be entitled to receive the consideration for such Property to be paid by such Pref Holder directly from such Pref Holder; provided, however, that if such Pref Holder requires that the conveyance of such Property be made by Seller, then Buyer shall re-convey such Property to Seller in exchange for a refund from Seller of the Good Faith Allocation of such Property, and Seller shall then convey such Property to such Pref Holder and be entitled to retain the consideration for such Property paid by such Pref Holder, in each of the foregoing cases, subject to any purchase price adjustments consistent with this Agreement.

3.2.5 Any Applicable Preferential Right or PPR must be exercised subject to all the terms and conditions of this Agreement, including the payment to Seller of the Performance Deposit upon exercise of the Applicable Preferential Right or PPR.

3.2.6 For the avoidance of doubt, Third Party Claims relating to or arising out of Applicable Preferential Rights or PPRs to the extent related to (i) a Good Faith Allocation or (ii) Buyer’s agreement to proceed with Closing prior to receipt of a written waiver or expiration of an Applicable Preferential Right or PPR (any such Third Party Claim, a “PPR Claim”) shall not be a Seller Retained Liability but shall be the responsibility of Buyer (without regard to any deductibles or thresholds contained in this Agreement that may be otherwise applicable). Buyer releases Seller Group from and shall fully protect, defend, indemnify and hold harmless Seller Group from and against any and all PPR Claims, no matter whether arising before, on or after the Closing Date. This indemnity and defense obligation shall apply regardless of cause or of any negligent acts or omissions (including active or passive, sole, concurrent or comparative negligence or gross negligence), strict liability, breach of duty (statutory or otherwise), violation of Law, or other fault of Seller Group, or any pre-existing defect.

3.2.7 Notwithstanding anything to the contrary herein, Buyer will have no obligation to purchase any Property that was treated as an Excluded Property pursuant to Section 3.2.3 after the Cut-Off Date.

3.3 Consents to Assignment.

3.3.1 If a required consent to assignment of a Property (other than Contracts or Customary Post-Closing Consents) has not been obtained prior to Closing, the Property with respect to which consent is required but not obtained shall be excluded from this Agreement and the Purchase Price shall be adjusted by the value allocated to such Property in Exhibits “A-1”, “A-2” or “A-3”, if any. Buyer remains obligated to

HOUSTON 1139976v.13

purchase from Seller the remainder of the Properties that are not subject to such unobtained required consent, subject to the terms and conditions of this Agreement. If Seller subsequently obtains any required consents prior to the Cut-Off Date not obtained prior to or at Closing, Seller shall promptly notify Buyer and within ten (10) Business Days after Buyer’s receipt of such notice, Seller shall sell, assign and convey to Buyer and Buyer shall purchase and accept from Seller such Properties pursuant to the terms of this Agreement and for the value allocated to such Properties in Exhibits “A-1”, “A-2” or “A-3”, if any, with respect to such affected Property (except “Closing Date” with respect to such Property shall mean the date of assignment of such Property from Seller to Buyer).

3.3.2 With respect to Contracts constituting Properties that require consent to assignment (other than Customary Post-Closing Consents), Seller shall use Commercially Reasonable Efforts to obtain such consent prior to Closing using the form of Consent Notice Letter attached hereto as Exhibit “H”, or as otherwise mutually agreed, and if such consent has not been obtained prior to Closing, upon the mutual agreement of the Parties, Seller shall execute and deliver such instruments and take such other actions as Buyer may reasonably request to carry out the intent of this Agreement and the transfer of such Contracts. Such instruments and actions shall include the execution of back-to-back agreements to effect the transfer to Buyer of the benefits and burdens of or on Seller under such Contracts which Seller is obligated to perform (provided that entering into such back-to-back agreements does not result in a breach of any obligations under any such Contract). In any such back-to-back agreement (i) Seller shall continue to be bound thereby and (ii) (A) Buyer shall perform and discharge fully all the obligations of Seller thereunder after the Effective Time and indemnify Seller for all Claims arising out of such performance by Buyer, (B) Seller shall, without further consideration therefor, pay, assign and remit to Buyer promptly all monies, rights and other considerations received in respect of such performance, (C) Seller shall promptly exercise or exploit the beneficial rights and options of Buyer under such Contract at Buyer’s expense and (D) if and when any such consent shall be obtained or such a Contract shall otherwise become assignable, Seller shall promptly assign, in a manner consistent with Section 2.1, its rights and obligations under such Contract to Buyer and Buyer shall, without the payment of any further consideration therefor, assume such rights and obligations and continue to indemnify Seller as stated above. To the extent that Seller is unable to assign a Contract with respect to which Seller has elected that this Section 3.3.2 shall apply, Seller shall use Commercially Reasonable Efforts to continue to seek consent to assignment of such Contract until the earlier of (x) the first anniversary of the Closing Date or (y) the date such Contract is terminated in accordance with its terms or otherwise at the direction of Buyer, to the extent such termination does not breach such Contract.

3.4 Applicable Consents and Waivers. Each Party hereby gives, and shall cause its Affiliates to give, any required consents and hereby waives, and shall cause its Affiliates to waive, any Applicable Preferential Rights or PPRs held by such Party or its Affiliates.

HOUSTON 1139976v.13

ARTICLE IV

TITLE REVIEW

4.1 Review of Title Records. After execution and delivery of this Agreement and prior to the Closing Date, Seller shall make available to Buyer and Buyer’s representatives, at reasonable times during Seller’s regular business hours and at their current locations (or such other locations as Seller designates) upon reasonable notice, for examination and copying, at Buyer’s expense, Records in Seller’s possession relating to title to the Properties. If Buyer requests copies of title Records, Seller shall use its Commercially Reasonable Efforts to provide the requested copies to Buyer at Buyer’s expense. Such review will be subject to the terms of the Confidentiality Agreement.

4.2 Waiver. Buyer (on behalf of Buyer Group and their successors and assigns) hereby irrevocably waives and releases for all purposes all objections and defects and Claims (whether known or unknown) associated with the title to the Properties, except for any special warranty of title given in the Assignment and ▇▇▇▇ of Sale or Deed. For the avoidance of doubt, this Section 4.2 shall not diminish or affect in any way the Parties’ rights and obligations under Section 19.6 or any indemnity provided in this Agreement.

ARTICLE V

CONDITION OF THE PROPERTIES

5.1 Access. Commencing after the Signing Date and until the Closing Date, but subject to the succeeding sentence, Seller shall provide Buyer access (during Seller’s regular business hours and to the extent it does not unreasonably interfere with Seller’s operations) to the Properties that it operates, and Seller shall use Commercially Reasonable Efforts to obtain permission for Buyer to gain access to the Properties that are operated by Third Parties after the Signing Date, to conduct a Phase I analysis of the same subject to the following conditions, it being agreed that Buyer and its Representatives may not conduct any Invasive Activities or inspections (other than a visual inspection) and may not operate any equipment or machinery in the course of such inspection. Notwithstanding anything otherwise provided in this Agreement, Buyer shall not have the right to access the ▇▇▇▇▇▇▇ Plant until Seller provides Buyer notice in accordance with Section 5.2.6 that Seller has completed the ▇▇▇▇▇▇▇ Plant Remediation Project. Such inspection shall be (a) conducted in accordance with the terms of the Confidentiality Agreement, (b) subject to any releases or other agreements required by the operator of the Properties, (c) only for the purpose of effecting the transactions contemplated by this Agreement and (d) subject at all times to Buyer’s and its Representatives’ compliance with Seller’s (or the applicable Third Party operator’s) applicable policies and procedures, including Seller’s (or the applicable Third Party operator’s) code of conduct, digital security, health, safety, security, and environmental policies and procedures. If, at any time, Seller believes in good faith that Buyer or any of its Representatives have not complied with Seller’s (or the applicable Third Party operator’s) applicable policies and procedures, then Seller may immediately terminate Buyer’s and its Representatives’ access to the Properties. Buyer shall be responsible for arranging, at its own cost, transportation to and from any such Properties. From and after the Signing Date until the Closing Date, Seller shall make available to Buyer and its Representatives, at reasonable times (which may be outside of normal business hours, such as evening hours and on weekends, if approved by Seller) and at their current locations (or such other locations as Seller designates)

HOUSTON 1139976v.13

upon reasonable notice, for examination and copying, all Records (other than title Records and title information, which Records and information are exclusively covered in Section 4.1) relating to the condition of the Properties insofar as the same are in possession of Seller or its Affiliates and, prior to the Signing Date, are not located at the Properties; provided, that Seller may restrict access and provision of information to the extent it reasonably believes necessary to (i) comply with existing confidentiality obligations owed to Third Parties (provided further that Seller shall use its Commercially Reasonable Efforts to secure waivers of any such confidentiality obligations), (ii) ensure compliance with antitrust and other Laws, (iii) preserve the secrecy of confidential information to the extent not related to the Properties and (iv) preserve a valid legal privilege relating to existing or anticipated Third Party Claims. From and after the Signing Date until the Closing Date, at reasonable times and upon reasonable notice, Seller shall afford Buyer and such Buyer’s Representatives reasonable access to selected employees of Seller Group that have been involved with the operation of the Properties solely to the extent such access does not disrupt the daily activities of such employees in any material respect. To the fullest extent permitted by Law, Buyer (on behalf of Buyer Group and their successors and assigns) shall indemnify, defend and hold harmless Seller Group, the other owners of interests in the Properties and their respective officers, directors, managers, employees, agents and representatives, from any and all Claims, including those for (1) any injury, illness or death of any Persons including Buyer Group, Seller Group or their respective Representatives; (2) damages to property (including damage to property of Third Parties, Seller Group, Buyer Group or their respective and/or of Buyer’s Representatives); and (3) damages to natural resources or environmental damage to or associated with the Properties to the extent caused by, arising out of, or resulting from the activities of Buyer Group or its Representatives in connection with any site visit or physical inspection of the Properties even if such indemnified event is caused by, arises out of or results from the active or passive, sole, concurrent or comparative negligence or gross negligence, strict liability, breach of duty (statutory or otherwise), violation of Law or other fault of the aforesaid indemnified parties, or any pre-existing defect, but not to the extent that such indemnified event or occurrence is caused by or the result of willful misconduct of such indemnified parties.

5.2 Alleged Adverse Conditions.

5.2.1 Subject to Section 5.2.6, as soon as reasonably practicable, but not later than the earlier of: (i) five (5) Business Days prior to the Closing Date, and (ii) forty-five (45) Days after the Signing Date (such time period, the “Adverse Condition Claim Period”), Buyer may notify Seller in writing of any Adverse Conditions with respect to any of the Properties (each, an “Alleged Adverse Condition”). Buyer’s notice asserting Alleged Adverse Conditions shall include a complete description and full explanation (including copies of any and all supporting documentation associated therewith) of each individual Alleged Adverse Condition being claimed and an estimate of the Prudent Cost Response that Buyer in good faith attributes to bringing such condition into compliance with Environmental Laws (such notice, an “Adverse Condition Notice”). The Parties shall meet from time to time as necessary in an attempt to agree on a resolution with respect to any outstanding Alleged Adverse Conditions timely raised hereunder.

HOUSTON 1139976v.13

5.2.2 Seller has the right, but not the obligation, to attempt, at its sole cost, to cure or remove any Alleged Adverse Condition with respect to the Properties of which it has been duly advised by Buyer during the Adverse Condition Claim Period or ▇▇▇▇▇▇▇ Plant Adverse Conditions Claim Period (as applicable). If prior to Closing or, solely with respect to Adverse Condition Notices delivered in accordance with Section 5.2.6, if within ten (10) Business Days after the end of the ▇▇▇▇▇▇▇ Plant Adverse Conditions Claim Period, Seller has given notice to Buyer that it elects to attempt to correct the Alleged Adverse Condition, then Seller may elect, by written notice to Buyer prior to the Closing, to continue to correct such condition to completion following Closing; provided that if such Alleged Adverse Condition is not corrected on or before one hundred eighty (180) Days after the Closing or one hundred eighty (180) Days after the end of the ▇▇▇▇▇▇▇ Plant Adverse Condition Claim Period: (i) with respect to Alleged Adverse Conditions raised pursuant to Section 5.2.6 or (ii) if the Adverse Condition Threshold Amount is first exceeded during the ▇▇▇▇▇▇▇ Plant Adverse Condition Claim Period, then, upon Seller’s receipt of written notice from Buyer of such non-completion given within thirty (30) Days following the end of such one hundred eighty (180) Day period, and subject to the right of Seller to initiate binding arbitration in accordance with the provisions set forth in Article 18 to resolve any dispute regarding any such alleged non-completion, Seller shall pay to Buyer, subject to Section 5.2.5, an amount equal to the remaining Prudent Cost Response for such Alleged Adverse Condition.

5.2.3 If the Parties are unable to agree as to the existence, validity, value or resolution of one or more of the Alleged Adverse Conditions prior to Closing (such inability to agree, an “Adverse Condition Dispute”), then (subject to Sections 15.2, 15.3 and 17.1) Buyer shall be obligated to Close and, except as to Alleged Adverse Conditions of which Seller has given notice to Buyer that it elects to correct (as provided above), at Seller’s election either: (i) the affected Property shall be an Excluded Property and the Purchase Price shall be reduced by the Good Faith Allocation of such Property, (ii) subject to Section 5.2.5, Seller shall indemnify Buyer pursuant to Section 8.3.2 and the Property shall remain a Property acquired by Buyer without any adjustment of the Purchase Price or (iii) subject to Section 5.2.5, the Property shall remain a Property acquired by Buyer and the Purchase Price shall be reduced by an amount equal to the lesser of the Good Faith Allocation of such Property and the Prudent Cost Response for such Alleged Adverse Condition; provided however, that either Party may initiate, within sixty (60) Days after Closing (but not later), binding arbitration in accordance with the provisions set forth in Article 18 to resolve any dispute arising prior to Closing regarding any Alleged Adverse Condition or the Prudent Cost Response thereof, except as to Alleged Adverse Conditions of which Seller has given notice that it elects to cure (as provided in Section 5.2.2). Notwithstanding the foregoing sentence, either Party may initiate, within sixty (60) Days after the one hundred eighty (180) Day cure period (but not later), binding arbitration in accordance with the provisions set forth in Article 18 to resolve any dispute regarding the failure to pursue diligently a cure or completion of the cure of an Alleged Adverse Condition that Seller has elected to cure.

5.2.4 Notwithstanding anything to the contrary in Article 18, any arbitration initiated under this Section 5.2 shall be exclusively and finally resolved by a single arbitrator if the Adverse Condition Dispute involves less than Five Million Dollars

HOUSTON 1139976v.13

($5,000,000) and by a panel of three arbitrators if the Adverse Condition Dispute involves more than Five Million Dollars ($5,000,000). Any such arbitrator (the “Environmental Referee”) shall be an environmental attorney(s) with at least ten (10) years experience in oil and gas facility environmental matters, shall have not at any point in the past ten (10) years represented or been adverse to either Party (or any of their Affiliates) and shall be selected by mutual agreement of Buyer and Seller within thirty (30) Days after the initiation of binding arbitration under Article 18, and absent such agreement, shall be selected by the Houston, Texas regional office of the AAA upon written request of either Party. Except as otherwise provided in the two preceding sentences, Adverse Condition Dispute arbitrations shall be conducted in accordance with Article 18.

5.2.5 Notwithstanding anything contained in this Agreement to the contrary but subject to Seller’s indemnification obligations set forth in Sections 8.2, 8.3 and 8.6, Buyer shall not be entitled to a Purchase Price adjustment, an indemnity or any other remedy relating to an Adverse Condition unless (i) a Claim for the Alleged Adverse Condition is asserted by Buyer within the Adverse Condition Claim Period or the ▇▇▇▇▇▇▇ Plant Adverse Conditions Claim Period (as applicable), (ii) the amount of the Prudent Cost Response for such individual Alleged Adverse Condition exceeds a threshold amount of One Million Dollars ($1,000,000) (the “Adverse Condition Threshold Amount”), and (iii) the Aggregate Transaction Claims for which Seller is responsible exceeds the Aggregate Deductible Amount (it being acknowledged and agreed that, subject to the provisions of Sections 8.2, 8.3 and 8.6, Buyer shall be solely responsible for and bear all costs and expenses or loss of value associated with each individual Alleged Adverse Condition asserted by Buyer hereunder up to the Adverse Condition Threshold Amount and for the aggregate of the Alleged Adverse Conditions to the extent they do not, when combined with the other Aggregate Transaction Claims for which Seller is responsible, exceed the Aggregate Deductible Amount). Seller’s election to attempt to cure, or to provide indemnity against an Alleged Adverse Condition, shall not constitute a waiver of Seller’s right to dispute the existence, nature or value of, or cost to cure, the Alleged Adverse Condition. Notwithstanding anything in this Agreement to the contrary, Buyer may not assert an Alleged Adverse Condition with respect to a Property (i) of which it is the operator or (ii) in which it owns an interest and with respect to which it is aware of such Alleged Adverse Condition.

5.2.6 Notwithstanding anything otherwise provided in this Section 5.2.6, Buyer shall have the right to provide Seller an Adverse Condition Notice related solely to the ▇▇▇▇▇▇▇ Plant for a period beginning on the Day Seller gives Buyer written notice that Seller has completed the ▇▇▇▇▇▇▇ Plant Remediation Project and ending on the Day which is thirty (30) Days later (the “▇▇▇▇▇▇▇ Plant Adverse Conditions Claim Period”). Except as otherwise expressly provided in this Section 5.2.6, any Alleged Adverse Conditions related to the ▇▇▇▇▇▇▇ Plant shall be subject to the procedures set forth in Section 5.2.

5.3 Waiver. Except as provided in the next sentence of this Section 5.3, Buyer (on behalf of Buyer Group and their successors and assigns) irrevocably waives and releases for all purposes all objections and Claims associated with the environmental,

HOUSTON 1139976v.13

physical, contractual and any other conditions of any Properties (including Adverse Conditions and Alleged Adverse Conditions) unless (a) asserted within the Adverse Condition Claim Period or the ▇▇▇▇▇▇▇ Plant Adverse Conditions Claim Period (as applicable) and as otherwise required by Section 5.2 and (b) in excess of the Adverse Condition Threshold Amount and the Aggregate Deductible Amount; provided however, all Alleged Adverse Condition Claims are deemed waived for all purposes by Buyer unless they are either settled by written agreement of the Parties or referred to arbitration under Article 18 in either case (x) within sixty (60) Days after the Adverse Condition Claim Period as provided in Section 5.2.3 or the ▇▇▇▇▇▇▇ Plant Adverse Conditions Claim Period (as applicable), or (y) within sixty (60) Days after the cure period lasting one hundred eighty (180) Days after the Adverse Condition Claim Period or the ▇▇▇▇▇▇▇ Plant Adverse Conditions Claim Period (as applicable), for those Alleged Adverse Conditions for which Seller provides Buyer notice that it will continue attempting to bring into compliance with Environmental Law after the Adverse Condition Claim Period or the ▇▇▇▇▇▇▇ Plant Adverse Conditions Claim Period (as applicable), and, subject to the foregoing exceptions, Buyer (on behalf of Buyer Group and their successors and assigns) irrevocably waives and releases and shall be solely responsible for any and all Claims it and they may have against Seller and Seller Group with respect to environmental, physical, contractual and any other conditions of the Properties (including Adverse Conditions and Alleged Adverse Conditions). For the avoidance of doubt, this Section 5.3 shall not diminish or affect in any way the Parties’ rights and obligations under any indemnities provided in this Agreement, including the indemnities set forth in Sections 8.3 and 8.6.

ARTICLE VI

ACCOUNTING

6.1 Products and Line Fill. Seller shall measure all Hydrocarbons, plant products and residue gas associated with the Properties and stored in tanks and vessels to the bottom of the applicable flange as of the Effective Time. Seller shall determine the Line Fill, if any, as of the Effective Time. Seller shall be entitled to the proceeds of such Hydrocarbons, helium and other inerts, plant products and residue gas produced or attributable to the Properties and saved for any period prior to the Effective Time, and shall be entitled to the Line Fill, if any, as of the Effective Time, all at the prices set forth in Schedule 6.1; provided, however, that all of the foregoing shall be less any applicable production tax, severance tax or similar Tax or other applicable deductions. Unless the actual amounts are readily available to Seller reasonably in advance of Closing, the estimated amounts to which Seller is entitled shall be included in the calculation of the Closing Purchase Price and shall be incorporated into the Preliminary Settlement Statement. The actual amounts to which Seller is entitled (to the extent the same differ from the estimate included in the Preliminary Settlement Statement) shall be accounted for in the Final Settlement Statement if they were not accounted for in the Preliminary Settlement Statement. Buyer shall be entitled to the proceeds of Hydrocarbons, helium and other inerts, plant products and residue gas produced or attributable to the Properties and saved for any period after the Effective Time.

6.2 Revenues, Expenses and Capital Expenditures. Except as expressly provided otherwise in this Agreement:

HOUSTON 1139976v.13

6.2.1 Seller is entitled to all revenues and accounts receivable attributable to the Properties it transfers, and is responsible for all expenses, accounts payable and capital expenditures attributable to the Properties it transfers, in each case to the extent they relate to the period prior to the Effective Time.

6.2.2 Seller also is entitled to the sum of Three Hundred Forty Thousand Dollars (US$340,000) per month (prorated on a daily basis for any partial month) (as an agreed reimbursement in lieu of Seller’s actual overhead) for the period from the Effective Time until the Closing Date.

6.2.3 Buyer is entitled to all revenues and accounts receivable attributable to the Properties it acquires, and is responsible for all expenses, accounts payable and capital expenditures attributable to the Properties it acquires, in each case to the extent they relate to the period from and after the Effective Time.

6.2.4 Seller shall estimate the above amounts and incorporate such estimate into the Preliminary Settlement Statement. The actual amounts (to the extent the same differ from the estimate included in the Preliminary Settlement Statement) shall be accounted for in the Final Settlement Statement.

6.3 Taxes.

6.3.1 Seller shall bear all Taxes attributable to the ownership or operation of the Properties prior to and including the Closing Date, in the case of income, franchise, margin and similar Taxes and prior to the Effective Time, in the case of all other Taxes, and all deductions, credits or refunds pertaining to the aforementioned Taxes, no matter when received, shall belong to Seller. Buyer shall bear all Taxes attributable to the ownership or operation of the Properties after the Closing Date, in the case of income, franchise, margin, and similar Taxes and on and after the Effective Time, in the case of all other Taxes and all deductions, credits or refunds pertaining to the aforementioned Taxes no matter when received, shall belong to Buyer. Property Taxes, whether or not based on production, shall be prorated based on a percentage of the assessment period occurring before and after the Effective Time. Property Taxes based on production (other than severance) shall be deemed by the Parties to apply to production in the Tax period for which the Tax is levied. Seller shall estimate all Taxes attributable to the ownership or operation of the Properties (excluding Seller’s income taxes, franchise taxes or margin taxes) and incorporate such estimate, to be reasonably acceptable to Buyer, into the Preliminary Settlement Statement. The actual amounts (to the extent the same differ from the estimate included in the Preliminary Settlement Statement) shall be accounted for by the Parties in the Final Settlement Statement.

6.3.2 Buyer acknowledges that Sales Tax may be due and owing as a result of Seller’s transfer of the Properties to Buyer and that Buyer is solely liable for any and all such Sales Tax. In Exhibit “A-2”, Buyer and Seller have agreed on the value of the tangible personal property being transferred. Seller shall provide Buyer with such documentation and information as Buyer shall reasonably request in connection with Buyer’s determination as to whether any of the tangible personal property being

HOUSTON 1139976v.13

transferred is eligible for an “isolated or occasional sale” exemption from Sales Tax. Prior to the delivery of the Preliminary Settlement Statement, Buyer shall provide Seller with documentation detailing the basis for Buyer’s allocation of the Purchase Price to any Property that is or is not subject to Sales Tax. Buyer shall pay any Sales Tax on its acquisition of all nonexempt tangible personal property by means of incorporating the amount into the Preliminary Settlement Statement (and the actual amounts, to the extent the same differ from the estimates included in the Preliminary Settlement Statement, shall be accounted for in the Final Settlement Statement) and Seller shall remit the Sales Tax collected from Buyer to the applicable Governmental Authority. If Buyer qualifies for any exemptions, at least three (3) Business Days prior to Closing, Buyer shall provide Seller with any exemption certificates required by state Law and Seller shall be released from collecting Sales Tax on otherwise taxable items that qualify for such exemptions. If Seller is required to pay any Sales Tax, interest or penalty thereon other than amounts taken into account in the Preliminary Settlement Statement (as adjusted by the Final Settlement Statement), Buyer shall reimburse Seller within thirty (30) Days after receipt of Seller’s written notice of the payment. Notwithstanding anything contained in this Agreement to the contrary, Buyer (on behalf of Buyer Group and their successors and assigns) releases Seller Group from and shall fully protect, defend, indemnify and hold harmless Seller Group from and against any and all Claims (no matter when asserted) relating to, arising out of, or connected with, directly or indirectly, Sales Tax resulting from or associated with Seller’s transfer of the Properties to Buyer. These indemnity and defense obligations will apply regardless of cause or of any negligent acts or omissions (including active or passive, sole, concurrent or comparative negligence), strict liability, breach of duty (statutory or otherwise), or other fault of Seller Group, or any pre-existing defect.

6.3.3 Buyer and Seller shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of original or amended Tax Returns and any audit, litigation, refund claim or other proceeding (each a “Tax Proceeding”) with respect to Taxes, provided that, except to the extent such cooperation relates to Taxes for which the Party asked to cooperate would be responsible under this Agreement, such requested Party (i) shall incur no additional costs, expenses, fees or liabilities or (ii) shall be reimbursed for all additional costs, expenses, fees or liabilities as a result of or connected with the request. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records, accounting data and information which are reasonably relevant to any such Tax Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Notwithstanding anything to the contrary in this Agreement, the Buyer and Seller agree (a) to retain all books and records with respect to Tax matters pertinent to the Properties relating to any taxable period beginning before the Closing Date until thirty (30) Days after the expiration of the statute of limitations (and, to the extent notified by Buyer or Seller, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any Governmental Authority and (b) to give the other Party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other Party so requests, the Buyer or Seller, as the case may be, shall allow the other Party to take possession of such books and records. Buyer and Seller further agree, upon

HOUSTON 1139976v.13

request, to use their Commercially Reasonable Efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated hereby).

6.3.4 Seller shall retain authority to settle any Tax Proceedings relating to Taxes for all tax periods prior to the Effective Time, and to file any amended Tax Returns resulting from any such settlement; provided, however, that Seller shall take no action with respect to Taxes that would increase Buyer’s liability for Taxes under this Agreement or otherwise. Buyer shall have authority to settle any Tax Proceedings relating to Tax for tax periods after the Effective Time and to file any amended Tax Returns resulting from any such settlement; provided, however, that Buyer shall take no action with respect to Taxes that would increase Seller’s liability for Taxes under this Agreement or otherwise.

6.4 Obligations and Credits. All Prepaid Amounts attributable to the Properties or other amounts paid by Seller (including amounts paid pursuant to an authorization for expenditure) prior to the Effective Time in respect of the Properties for services performed (or to be performed) or goods purchased (or to be purchased) after the Effective Time, and not otherwise taken into account in the Preliminary Settlement Statement, shall be reimbursed to Seller by Buyer as provided in this Section 6.4. Seller shall estimate the above amounts and incorporate such estimate into the Preliminary Settlement Statement. The actual amounts (to the extent the same differ from the estimates included in the Preliminary Settlement Statement) shall be accounted for in the Final Settlement Statement.

6.5 Preliminary Settlement Statement. No later than three (3) Business Days prior to the Closing Date, Seller shall submit to Buyer a preliminary settlement statement in substantially the form of Exhibit “I” (the “Preliminary Settlement Statement”) and include therewith an estimate, prepared in good faith, of the Purchase Price due by Buyer, taking into account the estimate of adjustments permitted hereunder as identified on such form. In connection with Seller’s preparation of the Preliminary Settlement Statement, Buyer shall cooperate by timely delivering to Seller all information in its possession relevant to the preparation of the Preliminary Settlement Statement that is requested by Seller and that relates to the Properties. Buyer shall have two (2) Business Days to review the Preliminary Settlement Statement. On the Day following the expiration of such two (2) Business Day review period, Buyer shall submit a written report containing any changes Buyer proposes to be made to the Preliminary Settlement Statement. The Parties shall attempt to agree on a final Preliminary Settlement Statement no later than one (1) Day prior to Closing. If the Parties are unable to agree by that date, Seller’s good faith estimate shall be used to determine the adjustments to the Purchase Price to be used at Closing in the Preliminary Settlement Statement.

6.6 Final Settlement Statement. As soon as reasonably practicable, but in no event later than one hundred eighty (180) Days after the end of the Transition Period, Seller shall deliver to Buyer a statement setting forth the adjustments to the Purchase Price pursuant to this Article 6 and any other adjustments to the Purchase Price expressly permitted hereunder, in substantially the form of the Preliminary Settlement Statement (the “Final Settlement Statement”). Upon request, Seller shall provide accounting support for any entry on the Final

HOUSTON 1139976v.13

Settlement Statement of which Buyer is not already in possession. As soon as reasonably practicable, but in no event later than forty-five (45) Days after Buyer receives the Final Settlement Statement, Buyer may deliver to Seller a written report containing any changes that Buyer proposes in good faith to be made to such statement, stating in reasonable detail its objections and the amounts to which it objects. If Buyer fails to timely deliver the written report to Seller containing changes Buyer proposes to be made to the Final Settlement Statement, the statement as delivered by Seller shall be deemed to be correct and shall be final and binding on the Parties and not subject to further review, audit, arbitration or legal proceedings. If Buyer timely delivers the written report to Seller containing changes Buyer proposes to be made to the Final Settlement Statement, then as soon as reasonably practicable, but in no event later than thirty (30) Days after Seller receives Buyer’s written report, the Parties shall meet and undertake to agree on the final adjustments to the Final Settlement Statement. If the Parties fail to agree on the final adjustments within the thirty (30) Day period, then either Party, by written notice to the Accounting Referee and the other Party, may submit the disputed items to the Accounting Referee for resolution (with copy concurrently delivered to the other Party). Each Party shall have the right to submit to the Accounting Referee (with copy concurrently delivered to the other Party) (i) a position statement on such disputed items within ten (10) Business Days after receipt of the notice to the Accounting Referee and (ii) a rebuttal statement to the other Party’s position statement within ten (10) Business Days after expiration of such ten (10) Business Day period. Failure of a Party to timely submit its position statement to the Accounting Referee shall constitute a waiver by such Party as to each particular item in dispute and its agreement to the amount proposed by the other Party. Either Party may request that the Accounting Referee accept or decline the appointment in writing within ten (10) Business Days after its receipt of the initial position statement. The Accounting Referee will make a determination resolving the disputed items to be reflected in the Final Settlement Statement based on the written position statements and rebuttal statements from Buyer and Seller and the Accounting Referee shall not take any testimony or hear any oral argument. The Accounting Referee may request, as it deems appropriate, any additional information from (and provide opportunity to rebut responses to) the Parties, with notice to both Parties of all such requests and the related responses. The Parties shall respond promptly to all requests from the Accounting Referee for additional information and clarification. The Accounting Referee shall address only those items in dispute and may not determine the disputed items to be greater than the greatest amount claimed by a Party or smaller than the smallest amount claimed by a Party. The Accounting Referee shall resolve the disputes within thirty (30) Days after expiration of the ten (10) Day rebuttal period. The decision of the Accounting Referee shall be in writing and will be final and binding on and non-appealable by the Parties, absent manifest error. The fees and expenses associated with the Accounting Referee shall be borne equally by Buyer and Seller and paid promptly upon receipt of the Accounting Referee’s invoices. Any amounts owed by one Party to the other Party as a result of the Final Settlement Statement shall be paid within fifteen (15) Business Days after the date when the amounts are agreed upon by the Parties, are deemed correct as provided above or the Parties receive the decision of the Accounting Referee, and the amounts included in the Final Settlement Statement shall be final and binding between the Parties and not subject to further audit, arbitration or other legal proceeding. The Accounting Referee shall act as an expert for the limited purpose of determining the specific disputed matter submitted by either Party and may not award damages or penalties to either Party with respect to any matter. Except as expressly provided herein, whenever the Accounting Referee is retained to resolve a dispute as provided

HOUSTON 1139976v.13

pursuant to this Agreement, the Accounting Referee may determine the issues in dispute following such procedures, consistent with the express provisions of this Agreement, as the Accounting Referee deems appropriate to the circumstances and with reference to the amounts in issue. Except as expressly provided herein, the Parties do not intend to impose any particular procedures upon the Accounting Referee, it being the desire of the Parties that any such disagreement shall be resolved as expeditiously and inexpensively as reasonably practicable.

6.7 Post-Closing Revenues. Except as expressly provided otherwise in this Agreement, Buyer shall pay Seller any and all amounts received after Closing by Buyer (to the extent not accounted for in the Final Settlement Statement or the Transition Services Agreement) that are attributable to the ownership of the Properties prior to the Effective Time. Except as expressly provided otherwise in this Agreement, Seller shall pay Buyer any and all amounts received after Closing by Seller (to the extent not accounted for in the Final Settlement Statement or the Transition Services Agreement) that are attributable to the ownership of the Properties after the Effective Time. The Party responsible for the payment of amounts received shall reimburse the other Party within ninety (90) Days after the end of the month in which such amounts were received by the Party responsible for payment and, if paid, no further adjustments shall be made with respect to such amounts in the Final Settlement Statement.

6.8 Post-Closing Expenses. Except as expressly provided otherwise in this Agreement, Seller shall reimburse Buyer for any and all costs and disbursements paid after Closing by Buyer (to the extent not accounted for in the Final Settlement Statement or the Transition Services Agreement) that are attributable to the ownership of the Properties prior to the Effective Time. Except as expressly provided otherwise in this Agreement, Buyer shall reimburse Seller for any and all costs and disbursements paid after Closing by Seller (to the extent not accounted for in the Final Settlement Statement or the Transition Services Agreement) that are attributable to the ownership of the Properties after the Effective Time. The Party responsible for the payment shall reimburse the other Party within ninety (90) Days after the end of the month in which the applicable invoice and proof of payment of such invoice were received by the Party responsible for payment and, if paid, no further adjustments shall be made with respect to such amounts in the Final Settlement Statement.

6.9 Audits. Seller has retained audit claims and other Claims against Third Parties related to periods as an Excluded Property, as more specifically described in Section 2.1. Notwithstanding anything in this Agreement to the contrary, (i) Seller shall have the right to conduct and participate in audits and other Claims related to joint operations or plant activities provided for under any construction, operation, gas processing, gas purchase, transportation or other Contract relating to the Properties in accordance with the terms thereof and any audits or Claims conducted by any Governmental Authority (whether or not being conducted as of the Closing Date), in each case to the extent any such audit or Claim relates to periods prior to the Closing Date and (ii) no audit or other Claim of Seller relating to the Properties is waived or released by Seller under this Agreement nor shall any indemnity in this Agreement affect any such audit Claim by Seller Group related to joint operations under any operating or other agreement relating to the Properties in accordance with the terms thereof to the extent any such audit relates to periods for which Seller Group is responsible under this Agreement.

ARTICLE VII

CASUALTY LOSS

7.1 Notice of Casualty Loss. From the Signing Date until Closing, Seller shall notify Buyer in a reasonably timely manner of each instance of Casualty Loss with respect to the Properties known to Seller.

7.2 Resolution of Casualty Loss.

7.2.1 If, after the Signing Date but prior to the Closing Date, any Property suffers a Casualty Loss, then (subject to Sections 15.2, 15.3 and 17.1) Buyer shall nevertheless be required to proceed to Closing with respect to such Property and Seller shall elect by written notice to Buyer prior to Closing either (i) to cause, at Seller’s sole cost and expense, any such Property affected by a Casualty Loss to be repaired or restored to a quality and condition comparable to that existing with respect to such Property immediately before the Casualty Loss using the Prudent Cost Response (in the case of expenditures necessary to comply with Environmental Laws), as promptly as reasonably practicable (which work may extend after the Closing Date, so long as Seller is diligently pursuing such repairs or restoration activities but not longer than one hundred eighty (180) Days after the Closing Date unless mutually acceptable to the Parties) or (ii) to make an appropriate monetary adjustment to the Purchase Price reflecting the “reduction in value” of such Casualty Loss in accordance with Section 7.2.2.

7.2.2 For the purposes of this Article 7, “reduction in value” due to a Casualty Loss is based on the principle that Seller should generally bear the costs of repair and restoration of such Property to a quality and condition comparable to that existing with respect to such Property immediately before the Casualty Loss, limited (i) in the case of expenditures necessary to comply with Environmental Laws, to the lesser of (A) the Prudent Cost Response and (B) the Good Faith Allocation applicable to the affected Property in Exhibits “A-1”, “A-2”, or “A-3” and (ii) in the case of expenditures not necessary to comply with Environmental Laws, to the Good Faith Allocation applicable to the affected Property in Exhibits “A-1”, “A-2”, or “A-3” and (iii) in all cases, to the amount which, when combined with the other Aggregate Transaction Claims for which Seller is responsible, exceeds the Aggregate Deductible Amount; provided that, if such repair or restoration costs result in the Properties having a quality or condition better than that existing immediately prior to the Casualty Loss, Buyer shall bear, or reimburse Seller if already incurred by Seller, an equitable portion of such repair or restoration costs. If Section 7.2.1(ii) is applicable, Seller shall notify Buyer at least ten (10) Days prior to the Closing of its proposed monetary adjustment and if the Parties have a dispute regarding the amount of the appropriate monetary adjustment (such dispute, a “Casualty Loss Dispute”), the Parties shall Close with an adjusting payment to Buyer in the amount of Seller’s good faith estimate of the reduction in value associated with such Casualty Loss and equitable allocation of repair or restoration costs to Buyer; provided, however, either Party may initiate, within thirty (30) Days (but not later) after the Closing Date, binding arbitration in accordance with Article 18 to resolve the Casualty Loss Dispute by delivering to the other Party a written notice setting forth the

HOUSTON 1139976v.13

Casualty Loss in dispute, the Properties affected, the specific description of the Casualty Loss, such Party’s good faith estimate of the value of such Casualty Loss and equitable allocation of cost, and any available documentation upon which such Party’s belief is based as to the existence, validity, value or cure of such Casualty Loss (such notice, a “Casualty Loss Dispute Notice”).

7.2.3 Notwithstanding anything to the contrary in Article 18, any arbitration initiated under this Section 7.2 shall be exclusively and finally resolved by a single arbitrator if the Casualty Loss Dispute involves less than Ten Million Dollars ($10,000,000) and by a panel of three arbitrators if the Casualty Loss Dispute involves more than Ten Million Dollars ($10,000,000). Any such arbitrator (the “Casualty Referee”) shall be an insurance loss consultant(s) with at least ten (10) years experience in oil and gas facility insurance loss analysis matters, shall have not at any point in the past ten (10) years represented or been adverse to either Party or any of their Affiliates and shall be selected by mutual agreement of Buyer and Seller within fifteen (15) Days after the delivery and receipt of the applicable Casualty Loss Dispute Notice, and absent such agreement, shall be selected by the Houston, Texas regional office of the AAA upon written request of either Party. Except as otherwise provided in the preceding two sentences, Casualty Loss Dispute arbitrations shall be conducted in accordance with Article 18; provided, if there is a difference between the good faith estimates of Seller and Buyer as to the reduction in value or equitable allocation of costs in excess of twenty percent (20%) of such arithmetical average, then the arbitrators shall be obligated to select as the reduction in value one of the good faith estimates proposed by the Parties, but not another amount in between the two estimates or otherwise. Any Claim for a Casualty Loss not referred to binding arbitration under Article 18 within thirty (30) Days after Closing shall be deemed waived.

7.2.4 In each case, Seller shall be entitled to retain all rights to insurance and other Claims against Third Parties with respect to the Casualty Loss, except to the extent the Parties otherwise agree in writing.

7.2.5 As used in Section 7.2, Prudent Cost Response shall not include costs related to Decommissioning, Asbestos and Related Liabilities, Process Safety Management and Disclosed Environmental Liabilities.

ARTICLE VIII

ALLOCATION OF RESPONSIBILITIES AND INDEMNITIES

8.1 Opportunity for Review.

Environmental Claims relating to, arising out of, or connected with, directly or indirectly (and whether asserted before or after Closing without extending the time limitations of Section 8.7), the ownership or operation of the Properties, or any part thereof, to the extent such Non-Environmental Claims are attributable to the period prior to the Effective Time and of which Buyer provides notice to Seller in accordance with Section 8.8 within twelve (12) months after the Closing Date, including Non-Environmental Claims relating to (A) injury, illness or death of any Person, (B) damages to or loss of any property or resources, (C) breach of contract, (D) common law causes of action such as active or passive, sole, concurrent or comparative negligence or gross negligence, strict liability, nuisance or trespass, or (E) violation of Law; and (b) all Claims arising out of any breach by Seller of Seller’s representations, warranties or covenants set forth in this Agreement. These indemnity and defense obligations apply regardless of cause or of any negligent acts or omissions (including active or passive, sole, concurrent or comparative negligence or gross negligence), strict liability, breach of duty (statutory or otherwise), violation of Law, or other fault of Buyer Group, or any pre-existing defect. Notwithstanding anything in this Agreement to the contrary, Seller has no obligation under this Agreement or otherwise to protect, defend, indemnify and hold harmless Buyer Group from and against any Non-Environmental Claims to the extent that Buyer is not entitled to a remedy therefor under Section 8.7. As of Closing, Buyer releases Seller Group from, and assumes and is solely responsible for, all Non-Environmental Claims either waived by Buyer or not subject to indemnification by Seller at the time in question under the terms of this Section 8.2.

8.3 Seller’s Environmental Indemnity Obligation.

8.3.1 If Closing occurs, then from and after the Closing Date, Seller hereby releases Buyer Group from, and, subject to the limitations set forth in Section 8.7 or elsewhere in this Agreement, shall fully protect, defend, indemnify and hold harmless Buyer Group from and against, all Environmental Claims (other than Decommissioning, Asbestos and Related Liabilities, Process Safety Management and Disclosed Environmental Liabilities) relating to, arising out of, or connected with, directly or indirectly (and whether asserted before or after Closing without extending the time limitations of Section 8.7), the ownership or operation of the Properties, or any part thereof, to the extent such Environmental Claims are attributable to the period prior to the Effective Time and of which Buyer provides notice to Seller in accordance with Section 8.8 within six (6) months after the Closing Date, including in all such cases Environmental Claims relating to (A) injury, illness or death of any Person, (B) damages to or loss of any property or resources, (C) breach of contract, (D) common law causes of action such as active or passive, sole, concurrent or comparative negligence or gross negligence, strict liability, nuisance or trespass, or (E) violation of Law.

8.3.2 If Closing occurs and Seller has elected under Section 5.2.2 to indemnify Buyer with respect to an Alleged Adverse Condition, then on and after the Closing Date, Seller shall release Buyer Group from, and, subject to the limitations set forth in Section 5.2 (including thresholds and time limitations therein) and Section 8.7 or elsewhere in this Agreement, shall fully protect, defend, indemnify and hold harmless Buyer Group from and against any and all Claims

HOUSTON 1139976v.13

relating to, arising out of, or connected with, directly or indirectly, such Alleged Adverse Condition (provided that this Section 8.3.2 shall not be applicable to any Environmental Claims, all of which are covered exclusively in accordance with Section 8.3.1).

8.3.3 These indemnity and defense obligations apply regardless of cause or of any negligent acts or omissions (including active or passive, sole, concurrent or comparative negligence or gross negligence), strict liability, breach of duty (statutory or otherwise), violation of Law, or other fault of Buyer Group, or any pre-existing defect. Notwithstanding anything in this Agreement to the contrary, Seller has no obligation under this Agreement or otherwise to protect, defend, indemnify and hold harmless Buyer Group from and against any Environmental Claims to the extent that Buyer is not entitled to a remedy therefor under Section 8.7 or elsewhere in this Agreement. As of Closing, Buyer (on behalf of Buyer Group and their successors and assigns) releases Seller Group from, and assumes and is solely responsible for, all Environmental Claims either waived by Buyer or not subject to indemnification by Seller at the time in question under the terms of this Section 8.3.

8.4 Buyer’s Non-Environmental Indemnity Obligation. If Closing occurs, then from and after the Closing Date, Buyer (on behalf of Buyer Group and their successors and assigns) hereby releases Seller Group from, and shall fully protect, defend, indemnify and hold harmless Seller Group from and against, (a) all Non-Environmental Claims relating to, arising out of, or connected with, directly or indirectly (and whether asserted before or after Closing without extending the time limitations of Section 8.7), the ownership or operation of the Properties, or any part thereof, to the extent such Non-Environmental Claims are attributable to (i) the Good Faith Allocation, (ii) applicable PPR, to the extent Buyer and Seller agree to close prior to receipt of a written waiver of such purchase rights, (iii) the period prior to the Effective Time (no matter when asserted) for any Non-Environmental Claims for which (x) Seller owes no indemnity under this Agreement or Seller’s indemnity obligation under this Agreement has expired, (y) the time period set forth in Section 8.7 has expired, or (z) the threshold and deductible amounts set forth in Section 8.7 are not met, and (iv) the period of time on or after the Effective Time, including Non-Environmental Claims relating to (A) injury, illness or death of any Person, (B) damages to or loss of any property or resources, (C) breach of contract, (D) common law causes of action such as active or passive, sole, concurrent or comparative negligence or gross negligence, strict liability, nuisance or trespass, or (E) violation of Law; and (b) all Claims arising out of any breach by Buyer of Buyer’s representations, warranties or covenants set forth in this Agreement. These indemnity and defense obligations apply regardless of cause or of any negligent acts or omissions (including active or passive, sole, concurrent or comparative negligence or gross negligence), strict liability, breach of duty (statutory or otherwise), violation of Law, or other fault of Seller Group, or any pre-existing defect.

8.5 Buyer’s Environmental Indemnity Obligation. Subject to Buyer’s rights to provide Seller an Adverse Condition Notice after Closing during the ▇▇▇▇▇▇▇ Plant Adverse Conditions Claim Period and to receive a Purchase Price adjustment therefore, if

HOUSTON 1139976v.13

Closing occurs, then from and after the Closing Date, Buyer (on behalf of Buyer Group and their successors and assigns) hereby releases Seller Group from, and shall fully protect, defend, indemnify and hold harmless Seller Group from and against, all Environmental Claims (including Decommissioning, Asbestos and Related Liabilities, Process Safety Management and Disclosed Environmental Liabilities) relating to, arising out of, or connected with, directly or indirectly (and whether asserted before or after Closing without extending the time limitations of Section 8.7), the ownership or operation of the Properties, or any part thereof, to the extent such Environmental Claims are attributable to (i) the period prior to the Effective Time for any Environmental Claims for which (x) Seller owes no indemnity under this Agreement or Seller’s indemnity obligation under this Agreement has expired, (y) the time period set forth in Section 8.7 has expired, or (z) the threshold and deductible amounts set forth in Section 8.7 are not met, (ii) the period prior to the Effective Time for any Environmental Claims for Decommissioning, Asbestos and Related Liabilities, Disclosed Environmental Liabilities or Process Safety Management and (iii) the period of time on or after the Effective Time, including in all such cases, Environmental Claims relating to (A) injury, illness or death of any Person, (B) damages to or loss of any property or resources, (C) breach of contract, (D) common law causes of action such as active or passive, sole, concurrent or comparative negligence or gross negligence, strict liability, nuisance or trespass, or (E) violation of Law.

8.6 Seller’s Retained Liabilities. If Closing occurs, then from and after the Closing Date, Seller shall release Buyer Group from, and shall fully protect, defend, indemnify and hold harmless Buyer Group from and against, any and all Third Party Claims relating to, arising out of, or connected with, directly or indirectly (and no matter when asserted) (collectively, “Seller Retained Liabilities”): (1) ownership or operation of the Excluded Properties including, with respect to such Excluded Properties, Third Party Claims relating to: (A) injury, illness or death of any Person, (B) damages to or loss of any property or resources, (C) breach of contract, (D) common law causes of action such as active or passive, sole, concurrent or comparative negligence or gross negligence, strict liability, nuisance or trespass, and (E) violation of Law, even if caused in whole or in part by the negligent acts or omissions (including active or passive, sole, concurrent or comparative negligence or gross negligence), strict liability, or other legal fault of any Person indemnified hereunder, (2) Seller’s failure to properly or timely pay royalties prior to the Effective Time, (3) the matters described in Schedule 10.1.4, and (4) any breach of Seller’s representations and warranties in Sections 10.1.1 through 10.1.3. Claims under this Section 8.6 may be made even if a Claim could also be asserted under Sections 8.2 or 8.3 and Claims under this Section 8.6 are not subject to any of the limitations set forth in Section 8.7.

8.7 Claim Periods and Deductibles. Seller will not have an obligation or liability to the Buyer Group under Sections 8.2 and 8.3 for:

HOUSTON 1139976v.13

8.7.1 any Claim under Sections 8.2, if Buyer has not provided Seller with an Indemnity Claim Notice within twelve (12) months from and after the Closing Date with respect to such Claim or any Claim under Sections 8.3, if Buyer has not provided Seller with an Indemnity Claim Notice within six (6) months from and after the Closing Date with respect to such Claim (other than Claims under Section 8.3.2, which shall survive indefinitely);

8.7.2 any Claim under Sections 8.2 or 8.3, if such Claim has a value of One Million Dollars ($1,000,000) or less (and these types of Claims shall not be counted in determining the Aggregate Deductible Amount);

8.7.3 any Claim to the extent the Aggregate Transaction Claims for which Seller is responsible do not exceed the Aggregate Deductible Amount (and Claims for which Seller is not responsible, including liabilities and obligations assumed by Buyer under Section 12.3 shall not be counted in determining the Aggregate Deductible Amount);

8.7.4 Seller’s aggregate liability for indemnification for Claims arising under this Agreement shall be limited to Twenty percent (20%) of the Purchase Price;

8.7.5 any Claim asserted against Seller to the extent Buyer Group has liability for the matters underlying such Claim pursuant to any Contract (other than this Agreement or any Operative Documents) between the Parties or their respective Affiliates (by way of example, and not in limitation thereof, under any construction, operation, gas processing, gas purchase, transportation or other agreement relating to the Properties);

8.7.6 any Consequential Damages resulting from or arising out of any Claim by Buyer (other than Consequential Damages awarded against Buyer as a result of a Third Party Claim); and

8.7.7 any Claims expressly waived by Buyer in this Agreement or other written agreement.

8.8 Notice of Claims. If a Claim is asserted against a Person for which a Party may have an obligation of indemnity and defense under this Article 8 or any other provision of this Agreement (an “Indemnity Claim”), the indemnified Person shall give the indemnifying Party prompt written notice of the underlying Claim setting forth the particulars associated with the underlying Claim (including a copy of the written underlying Third Party Claim, if any) as then known by the indemnified Person (“Indemnity Claim Notice”). For Indemnity Claims with respect to which the threshold limitations in Section 8.7 apply, an Indemnity Claim shall be deemed to have been made (subject to the other provisions of Section 8.7) upon the indemnified Person’s providing an initial Indemnity Claim Notice to the indemnifying Party stating that the Claim underlying the Indemnity Claim could reasonably be expected in good faith to exceed the applicable threshold amount. The indemnified Person shall, to the extent practicable, give an Indemnity Claim Notice within such time as shall allow the

HOUSTON 1139976v.13

indemnifying Party a reasonable period in which to evaluate and timely respond to the underlying Claim; provided, however, that (a) failure to do so shall not affect an indemnified Person’s rights hereunder except for, and only to the extent of, any incremental costs incurred by the indemnified Person with respect to the Indemnity Claim resulting from the failure to give notice; (b) the foregoing shall not extend the time periods set forth in Section 8.7 (if applicable to the Claim), but if an Indemnity Claim Notice is given to an indemnifying Party within the applicable time period (if any) with respect to such Claim set forth in Section 8.7, such Indemnity Claim Notice shall be effective, subject to the other provisions of Article 8, as to costs and expenses incurred or suffered after the expiration of any such time period, with respect to the matter generally described in such Indemnity Claim Notice; and (c), without extending the time periods set forth in Section 8.7, the indemnified Person shall not be required to provide an Indemnity Claim Notice unless and until such Person believes that the Claim underlying the Indemnity Claim could reasonably be expected in good faith to exceed the applicable threshold (if any) set forth in Section 8.7.

8.9 Defense of Third Party Claims. Upon receipt of an Indemnity Claim Notice involving a Third Party for which an indemnifying Party believes it may have an obligation of indemnity under this Agreement, the indemnifying Party shall, if it so elects in accordance with this Section 8.9 (without prejudice to its right to contest its obligation of indemnity under this Agreement), assume the defense of the Third Party Claim with counsel selected by the indemnifying Party and reasonably satisfactory to the indemnified Person as provided herein below. The indemnified Person shall cooperate in all reasonable respects; provided, however, it shall not be obligated to incur any out-of-pocket cost or expense in such defense. If any Third Party Claim involves a fact pattern wherein each Party may have an obligation to indemnify the other Party, each Party may assume the defense of and hire counsel for that portion of the Third Party Claim for which it may have an obligation of indemnity. In all instances, the indemnified Person may employ separate counsel and participate in the defense of any Third Party Claim; provided, however, if the indemnifying Party has assumed the defense of a Third Party Claim pursuant to this Section 8.9 and has agreed to indemnify the indemnified Person, the fees and expenses of counsel employed by the indemnified Person shall be borne solely by the indemnified Person. If (a) the underlying Third Party Claim meets any applicable per-Claim threshold, (b) the underlying Third Party Claim plus all previously asserted underlying Claims that meet any applicable per-Claim threshold have exceeded the Aggregate Deductible Amount, if applicable in the circumstances, and (c) the indemnifying Party elects, by written notice, to undertake the defense of the Third Party Claim within thirty (30) Days after receipt of the Indemnity Claim Notice, then, subject to the limitations on indemnity contained in this Agreement, (i) the indemnifying Party shall defend the indemnified Person against such Third Party Claim, (ii) the indemnifying Party shall pay any judgment entered or settlement with respect to such Third Party Claim, (iii) the indemnifying Party shall not consent to the entry of any judgment or enter into any settlement with respect to such Third Party Claim that (A) does not include a provision whereby the plaintiff or claimant in the matter releases the indemnified Person from all liability with respect to such Third Party Claim and (B) would restrict such indemnified Person’s ability to conduct its business, and (iv) the indemnified Person shall not consent to the entry of any judgment or enter into any settlement with respect to such Third Party Claim without the indemnifying Party’s prior written consent, not to be unreasonably withheld, conditioned or delayed. If the indemnifying Party has not elected to undertake the defense of a Third Party Claim, or if the indemnifying Party assumes the defense of a Third Party Claim

Notwithstanding anything to the contrary contained in this Agreement, if there is a failure of any condition to be satisfied in favor of a Party or if there is a breach of any representation or warranty or pre-Closing covenant of another Party to the Knowledge of the first Party and the first Party elects to proceed with the Closing, then, except to the extent such failure or breach is described in a written notice given by the first Party to the second Party prior to the Closing Date, the condition that is unsatisfied or the representation, warranty or pre-Closing covenant that is breached at the Closing Date will be deemed waived by such first Party, and, absent a written waiver, the terms of which shall govern, such first Party will be deemed to fully release and forever discharge the other Parties on account of any and all Claims with respect to the same, including any Claims for indemnification hereunder, and such Party agrees not to make, file or bring any Claim with respect to such released Claims. If such written notice is given prior to Closing, and Closing does occur, this provision shall have no impact on either Party’s rights or obligations pursuant to Article VIII insofar as applicable to the failure or breach described in such notice. The term “pre-Closing covenant” refers to a covenant to the extent applicable to a period prior to the Closing.

ARTICLE XVII

TERMINATION

17.1 Grounds for Termination. Subject to Section 17.2, this Agreement may be terminated (except for the provisions referenced in Section 17.2) at any time prior to Closing upon the occurrence of any one or more of the following:

17.1.1 by the mutual written agreement of the Parties;

17.1.2 by Buyer, if any of the conditions set forth in Sections 15.2 or 15.3 shall have become incapable of fulfillment, and shall not have been waived by Buyer (provided, however, that Buyer is not in material breach of its representations, warranties or covenants contained in this Agreement and, further provided, that Buyer shall have given Seller at least five (5) Business Days in which to attempt to cure the situation and at the end of such cure period, the relevant condition precedent remains unable to be satisfied prior to the Closing Date); provided however, the cure period shall be extended for a further twenty (20) Business Days if Seller is using good faith and reasonable efforts to satisfy such condition and it is reasonably possible that such condition can be satisfied within the cure period as extended;

17.1.3 by Seller, if any of the conditions set forth in Sections 15.1 or 15.3 shall have become incapable of fulfillment, and shall not have been waived by Seller (provided, however, that Seller is not in material breach of its representations, warranties or covenants contained in this Agreement);

17.1.4 by either Party, if under the HSR Act or otherwise, the Federal Trade Commission or the Department of Justice shall have commenced or threatened to commence any proceeding to delay or enjoin or seek damages in respect of the transactions evidenced by this Agreement (“threatened,” for purposes of this Section 17.1.4, means an actual vote of the Commissioners of the Federal Trade Commission to commence such a proceeding);

HOUSTON 1139976v.13

17.1.5 by either Party, if consummation of the transactions contemplated by this Agreement would violate any non-appealable final order, decree or judgment of any Governmental Authority enjoining, restraining or prohibiting (i) Seller’s proposed sale of Properties to Buyer, or (ii) the consummation of the transactions contemplated by this Agreement;

17.1.6 by either Party, if any material Governmental Approval of the consummation of the transactions contemplated under the terms of this Agreement (except for those Customary Post-Closing Consents) is required and not obtained from any Governmental Authority having appropriate jurisdiction;

17.1.7 by Seller, if Seller has not received the Performance Deposit by the date and time provided in Section 2.5;

17.1.8 by either Party, if the Termination Defect Amount meets or exceeds the requisite amount set forth in the definition of such term; or

17.1.9 by either Party, if Closing has not occurred on or before the Termination Date, for any reason (provided, however, that the terminating Party is not in material breach of its representations, warranties or covenants contained in this Agreement).

17.2 Effect of Termination. Except as otherwise provided in this Section 17.2, if this Agreement is terminated in accordance with Section 17.1, neither Party shall have any right or remedy against the other Party as a result of such termination, except for any breach of this Agreement and except that performance of the indemnity obligation in Section 5.1 and the obligations contained in Section 14.13 and Articles 17, 18 and 19 shall survive termination of this Agreement. If Closing does not occur, Seller shall refund the Performance Deposit to Buyer unless Closing did not occur because of Buyer’s breach of this Agreement, including breach of Buyer’s representations and warranties herein, or Buyer’s failure or refusal to Close that is not permitted by the terms of this Agreement, in any of which events Seller shall be entitled to retain the Performance Deposit as liquidated damages and not a penalty or Consequential Damages. The provisions for payment of the Performance Deposit as liquidated damages in this Section 17.2 have been included because, in the event of termination of this Agreement as described in Section 17.1, both Buyer and Seller agree that the actual damages that would be incurred by Seller are reasonably expected to approximate the amount of the Performance Deposit and because the actual amount of such damages would be difficult, if not impossible, to measure precisely and Buyer waives any rights to claim otherwise, and Seller shall have no liability or obligation to any member of the Buyer Group relating to or arising out of the Performance Deposit.

17.3 Dispute over Right to Terminate. Each Party acknowledges and agrees that if the Closing fails to occur, or is rendered incapable of occurring, as a result of the breach by such Party of any term or provision of this Agreement (such breach, a “Closing Failure Breach”), the other Party would be damaged irreparably. Accordingly, each Party agrees that the other Party shall be entitled to an injunction or injunctions to prevent any such Closing Failure Breach and to enforce specifically this Agreement and the terms and provisions hereof in

HOUSTON 1139976v.13

any action instituted in any court of the United States or any state thereof having jurisdiction over the Parties and the matter. If there is a dispute between the Parties over the right of a Party to terminate this Agreement, the Closing shall not occur on the Closing Date. A Party that disputes the right of the other Party to terminate this Agreement may, within thirty (30) Days after the Closing Date, initiate litigation to resolve the dispute. If the Party that disputes the right of the other Party to terminate this Agreement fails (for any reason whatsoever) to initiate litigation within such thirty (30) Day period, this Agreement shall be deemed properly terminated as of the original date of termination (without prejudice to Seller’s right to retain the Deposit together with any interest earned thereon pursuant to Section 17.2), and the Party that disputes or has the right to dispute the termination of this Agreement, on behalf of itself, its Affiliates, and the officers, directors, agents, employees, successors and assigns of itself and its Affiliates, irrevocably waives any and all Claims it and they may have against the terminating Party for termination of this Agreement.

17.4 Confidentiality. Both Parties agree to be bound by the terms and conditions of the Confidentiality Agreement as if each were a signatory party thereto and to cause their respective Affiliates to comply therewith as if they were signatories thereto. Notwithstanding the termination of this Agreement or any other provision of this Agreement to the contrary but subject to the next sentence of this Section 17.4, the terms of the Confidentiality Agreement, shall remain in full force and effect. If Closing of the transaction contemplated under the terms of this Agreement occurs, the terms and conditions of the Confidentiality Agreement shall terminate (which termination shall be effective as of the Closing) as and to the extent provided in Section 19.4 but shall remain in full force and effect as to all Excluded Properties and other assets, properties and information of or about Seller Group, including the Seller Standards.

ARTICLE XVIII

ARBITRATION

18.1 Friendly Consultation.

18.1.1 In the event of any Arbitrable Dispute, the Parties shall attempt in the first instance to resolve such dispute through friendly consultations between the Parties. The Parties agree to attempt to resolve all Arbitrable Disputes arising hereunder promptly, equitably and in a good faith manner.

18.1.2 If the Parties are unable to resolve the Arbitrable Dispute through friendly consultation, any Party may request by written notice resolution by management-level negotiations by the Parties. Within fifteen (15) Days after delivery of the notice, each Party shall submit to the other Party a written response. The notice and the response each shall include (i) a brief summary of that Party’s position and (ii) the name and title of that Party’s representative and of any other Person who will accompany the representative to the meeting. Within fifteen (15) Days after delivery of such written response, the representatives of both Parties (and any accompanying Persons) shall meet at a mutually acceptable time and place, and thereafter continue to meet as often as they reasonably deem necessary, to use their good faith and reasonable efforts to attempt to resolve the dispute. All negotiations pursuant to this clause shall be confidential and

HOUSTON 1139976v.13

shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

18.2 Arbitration.

18.2.1 an Arbitrable Dispute has not been resolved within forty-five (45) Days after delivery of the notice requesting management-level negotiations, or if the Parties failed to meet within fifteen (15) Days after delivery of such notice, then the Arbitrable Dispute may be submitted by any Party to binding arbitration pursuant to the terms of this Article 18, regardless of whether such Arbitrable Dispute otherwise would be considered justiciable or ripe for resolution by any court or arbitral tribunal, by giving written notice thereof to the other Party; provided, however, that in no event shall a Party have the right to submit the Arbitrable Dispute to arbitration if the institution of legal or equitable proceedings based on such Arbitrable Dispute would be barred by any applicable survival period under this Agreement or the applicable statute of limitations. A Party submitting such Arbitrable Dispute to binding arbitration shall do so in accordance with the AAA commercial arbitration rules and procedures then in effect (the “AAA Rules”), with a copy of its submission to the other Party.

18.2.2 The arbitration shall take place in Houston, Texas.

18.2.3 The submitting Party’s notice initiating binding arbitration must describe in reasonable detail the nature of the dispute and the facts and circumstances relating thereto and identify the arbitrator it has appointed. The other Party shall respond to the submitting Party within thirty (30) Days after receipt of the submitting Party’s notice, agreeing to the designation of its arbitrator as the single arbitrator or identifying the arbitrator such other Party has appointed. All arbitrators must be neutral parties who are not and have not been an Affiliate of any Party, nor an employee, director, officer, shareholder, owner, partner, agent or a contractor of or legal counsel to any Party or any Affiliate of such Party or such related Persons, either presently or at any time during the previous ten (10) years. For these purposes, the term “neutral” shall not disqualify a Person owning securities in mutual funds that own securities of Buyer, Seller or their respective Affiliates. Arbitrators must have not less than fifteen (15) years experience as a lawyer and have a legal practice that includes significant experience in energy asset acquisition and divestiture transactions of similar complexity as the transactions contemplated in this Agreement. A single arbitrator shall control the proceedings if appointment of a single arbitrator is accepted by all Parties; if the Arbitrable Dispute involves Ten Million Dollars ($10,000,000) or less; or if the Arbitrable Dispute involves more than Ten Million Dollars ($10,000,000) and the other Party fails to appoint an arbitrator within the required thirty (30) Day period. If the Arbitrable Dispute involves more than Ten Million Dollars ($10,000,000) and the other Party timely appoints an arbitrator, the arbitral tribunal shall consist of three (3) arbitrators, comprised of the two Party-appointed arbitrators and a third arbitrator to be appointed by the two Party-appointed arbitrators within thirty (30) Days after the second arbitrator has been appointed. The third arbitrator shall act as chairman of the panel. If the Arbitrable Dispute involves Ten Million Dollars ($10,000,000) or less and the Parties are unable to agree on a single arbitrator within forty-five (45) Days after the submitting Party’s notice,

HOUSTON 1139976v.13

then either Party may request the Houston, Texas office of the AAA (or, if there is no such office, the office of the AAA serving Houston, Texas) to select the single arbitrator, with due regard given to the selection criteria above and input from the Parties. If the Arbitrable Dispute involves more than Ten Million Dollars ($10,000,000) and the two Party-appointed arbitrators are unable to agree on a third arbitrator within thirty (30) Days after the second arbitrator has been appointed, then either Party may request the Houston, Texas office of the AAA to select the third arbitrator, with due regard given to the selection criteria above and input from the Parties. The AAA shall select the single or third arbitrator, as the case may be, as provided in the AAA Rules not later than thirty (30) Days after such request. In the event the AAA should fail to select an arbitrator within such thirty (30) Day period, then either Party may petition the Chief United States District Judge for the Southern District of Texas to select the applicable single or third arbitrator, as the case may be, due regard being given to the selection criteria above and input from the Parties.

18.2.4 The arbitrators shall follow the Code of Ethics for Arbitrators in Commercial Disputes approved by the American Bar Association House of Delegates on February 9, 2004 and approved by the Executive Committee of the Board of Directors of the AAA.

18.2.5 Within thirty (30) Days after the selection of the panel (whether it be a single arbitrator or three arbitrators), each Party shall submit to the arbitrator(s) (with copies to the other Party) such Party’s position statement and proposal for resolution of the Arbitrable Dispute, together with any supporting data or materials. Within ten (10) Business Days after such thirty (30) Day period, each Party shall be permitted to submit to the arbitrator(s) (with copies to the other Party) such Party’s rebuttal statement to the other Party’s position statement and a revised proposal, if any, for resolution of the Arbitrable Dispute, together with any supporting data or materials. Within forty-five (45) Days after the expiration of the rebuttal period, the arbitrator(s) shall hold a hearing in Houston, Texas during which the Parties may present argument in support of their respective proposals. The arbitrator(s) (by majority rule if there are three (3) arbitrators) shall determine the outcome of the Arbitrable Dispute by selecting, for each disputed point, either the proposed resolution submitted by one Party or the proposed resolution submitted by the other Party; provided that, if the Parties jointly notify in writing the arbitrators of their agreement on any particular disputed issue, the arbitrators shall follow the agreed outcome on such issue. The arbitrators’ decision shall be by majority rule if there are three (3) arbitrators and the award shall be rendered in writing. The arbitrators shall endeavor to render the award within sixty (60) Days following commencement of the hearing.

18.2.6 The arbitration shall proceed under the AAA Rules and shall be governed by the Federal Arbitration Act, 9 U.S.C. Section 1, et. seq. The arbitrators may, in their discretion, limit or expand discovery in any arbitration proceeding as they shall determine is appropriate in the circumstances, taking into account the needs of the disputing Parties and the desirability of making discovery expeditious and cost-effective. The arbitrators shall also permit the exchange of lists of exhibits and witnesses in advance of the hearing.

HOUSTON 1139976v.13

18.2.7 The decision of such arbitrators shall be final and in writing. The Parties expressly covenant and agree to be bound by the award of the arbitrators as a final determination of the matter in dispute, and a judgment thereon may be entered in any court of competent jurisdiction. In rendering an award the arbitrators shall abide by (i) the terms and conditions of this Agreement and (ii) the Laws of the State of Texas. The arbitrators shall not have jurisdiction or authority to add to, detract from or alter in any way the provisions of this Agreement or to waive, alter, amend, revoke or suspend any of the provisions of this Agreement, provided, however, that the arbitrators shall have the power to decide all questions with respect to the interpretation and validity of this Section 18.2.

18.2.8 The arbitrators may award equitable relief, such as specific performance, as well as monetary damages for any Party’s breach of such Party’s obligations under this Agreement, but in no event may the arbitrators award Consequential Damages or any other damages expressly waived in Section 8.12 or that is contrary to applicable Law.

18.2.9 All fees and costs of any arbitration will be assessed and paid, in the absence of the disputing Parties’ agreement to the contrary, equally by all disputing Parties; provided that, the arbitrators may apportion the costs of arbitration between the Parties in such manner as it deems reasonable, taking into account the circumstances of the Arbitrable Dispute, the conduct of the Parties and the result of arbitration. The arbitration panel shall be empowered and directed to enter an award by default against any Party to the arbitration who declines to pay when required by the arbitration panel its share of such fees and costs. In addition, the arbitration panel shall be entitled to award to a Party such Party’s reasonable attorneys’ fees and expert fees, as determined by the arbitration panel considering those factors mentioned in the first sentence of this Section 18.2.9, incurred in connection with such Party’s preparation for and participation in the arbitration.

18.2.10 Except to the extent required by Law or court or administrative order, no Party, arbitrator, representative, counsel or witness shall disclose or confirm to any Person not present at the negotiation or arbitration any information about the negotiation or arbitration proceeding or hearings, including the names of the parties and the arbitrators, the nature and amount of the claims, the financial condition of any party, the expected date of the hearing or the award made.

18.2.11 To the extent, the Arbitrable Dispute arises in whole or in part under Article 5 or Article 7 of this Agreement, this Article 18 shall apply to the extent amended by such Article.

18.2.12 Notwithstanding the other provisions set forth in this Article 18, a court of competent jurisdiction may issue a pre-arbitral injunction, pre-arbitral attachment, or other order in aid of arbitration proceedings and the enforcement of any award. Without prejudice to such provisional remedies as may be available under the jurisdiction of a court, the arbitration panel shall have full authority to ▇▇▇▇▇

▇▇▇▇▇▇▇ 1139976v.13

provisional remedies and to direct the Parties to request that any court modify or vacate any temporary or preliminary relief issued by such court.

18.3 Continuing Obligations and Rights. When any Arbitrable Dispute occurs, the Parties shall continue to make payments of undisputed amounts in accordance with this Agreement, and the Parties shall otherwise continue to exercise their respective rights, and fulfill their respective obligations, under this Agreement. While any friendly consultations or arbitration are pending, no Party shall exercise any other remedies hereunder arising by virtue of the matters in dispute; provided, however, a Party’s right to terminate this Agreement pursuant to Article 17 shall not be suspended during the pendency of any friendly consultations or arbitration.

18.4 Interim Remedies. Before a notice to arbitrate is given or prior to the selection of the arbitrator(s), nothing contained herein shall prevent a Party from applying to a court that would otherwise have jurisdiction for provisional or interim measures. After the arbitrator(s) has been selected, the arbitrator(s) shall have sole jurisdiction to hear such applications, except that any measures ordered by the arbitrator(s) may be immediately and specifically enforced by a court otherwise having jurisdiction over the Parties.

19.2 Costs and Post-Closing Consents. Notwithstanding other provisions of this Agreement, Buyer shall be responsible for recording and filing documents associated with the assignment of the applicable Properties to it and for all costs and fees associated therewith, including filing the assignments and deed(s) with appropriate Governmental Authorities as required by applicable Law. Buyer shall also be responsible for the payment of any and all transfer, Sales, gross receipts, use or similar Taxes or assessments resulting from its acquisition of Properties as contemplated by this Agreement. As soon as practicable after recording or filing, Buyer shall furnish Seller with all recording data and evidence of all required filings. Buyer shall also be responsible for obtaining Customary Post-Closing Consents applicable to the Properties acquired by it under this Agreement and all costs and fees associated therewith. Except as expressly provided otherwise in this Agreement, all fees, costs and expenses incurred by the Parties in negotiating this Agreement and in consummating the transactions contemplated by this Agreement shall be paid in full by the Party that incurred such fees, costs and expenses.

19.3 Records.

19.3.1 Seller and Buyer shall meet within thirty (30) Business Days after the Closing Date and from time to time thereafter in order to plan an orderly transition of the Records to Buyer. Within a commercially reasonable period (which is anticipated to be at least one hundred twenty (120) Days after the end of the Transition Period), Seller shall make available for Buyer to pick up or for Buyer to have delivered (at Buyer’s sole expense) to a location of Buyer’s choice the Records that are maintained by Seller or its Affiliates (or, in the case of Records located at the Properties, make such Records available to Buyer at such locations); provided, however, Seller may retain copies or originals of any or all Records. If Seller retains originals of Records under this Section 19.3, Seller will deliver to Buyer scanned electronic copies of such original Records at Seller’s expense.

19.3.2 Seller is not obligated to create any Records for Buyer or to provide Records in a form or format other than the form or format in which they exist as

HOUSTON 1139976v.13

of the Signing Date or to provide them to Buyer in any sequence or priority. Seller will provide the Records to Buyer in the formats and on media used by Seller, or native to the system in which such data or information resides. If Seller has any Records in an electronic format, Seller will deliver such Records in such electronic format. If Buyer requests any Records in a specific format or report form and Seller is able, with Commercially Reasonable Efforts, to provide such Records in such requested format or report form, Buyer will reimburse Seller for all costs incurred by Seller related to the provision of such Records in such requested format or report form.

19.3.3 If Buyer desires to have copies of Records prior to the time by which Seller is obligated to furnish the Records to Buyer under this Section 19.3, Seller will use Commercially Reasonable Efforts to cause the copies requested by Buyer to be made and delivered to Buyer; provided, however, that Seller has no obligation to provide Buyer with copies of Records prior to Closing and if Seller is willing to provide copies of any such Records prior to Closing, Buyer shall reimburse Seller for all costs of copying and providing such Records to Buyer. The provisions of this Section 19.3.3 are without prejudice to Buyer’s rights under Sections 4.1 and 5.1.

19.3.4 Buyer shall maintain the Records received from Seller for seven (7) years after the Closing Date and afford Seller reasonable access to the Records and a right to copy the Records at Seller’s expense as reasonably requested by Seller. Buyer may retain the Records in electronic format in its ordinary course of business. If Buyer desires to destroy the Records within such seven (7) year period, it shall notify Seller prior to such destruction, and provide Seller an opportunity to take possession of them at Seller’s expense. In addition, Buyer shall afford Seller full access to records and data produced after the Closing Date and reasonably requested by Seller in connection with any Claim for indemnity by Buyer under this Agreement (excluding, however, attorney work product and attorney-client communications entitled to legal privilege), and a right to copy such records and data at Seller’s expense. Furthermore, Seller shall afford Buyer full access to records and data which have not been delivered to Buyer and which are reasonably requested by Buyer in connection with any Claim for which Buyer is responsible under this Agreement (excluding, however, attorney work product and attorney-client communications entitled to legal privilege), and a right to copy such records and data at Seller’s Expense if such records or data should have been delivered to Buyer as Records, and, in all other cases, at Buyer’s expense.

19.4 Post-Closing Confidentiality of Records. Effective upon the execution of this Agreement, Buyer hereby ratifies the Confidentiality Agreement and agrees to be subject thereto, as if each entity comprising Buyer was a signatory hereto. Effective upon, and only upon, the Closing with respect to a particular Property:

19.4.1 with respect to such information to the extent that it relates solely to such Property and liabilities assumed with respect thereto, (x) Buyer shall have no further obligations of confidentiality to Seller under the Confidentiality Agreement in respect thereof and (y), except to the extent related to the enforcement of its rights or defense of its obligations under this Agreement, Seller hereby agrees to treat such information insofar as it pertains solely to such Property and assumed liabilities with

HOUSTON 1139976v.13

respect thereto as confidential information of Buyer in accordance with the terms of the Confidentiality Agreement; and

19.4.2 with respect to such information to the extent that it does not relate solely to such Property and liabilities assumed with respect thereto, such information shall remain subject to the terms and conditions of the Confidentiality Agreement on and after the Closing Date, and Buyer hereby acknowledges its obligation to treat such information as confidential information of Seller in accordance with the terms of the Confidentiality Agreement.

19.5 GAAP/Financial Reporting. Except as otherwise expressly provided in this Agreement, all accounting matters under this Agreement shall be determined in accordance with GAAP. With respect to each Party’s financial reporting obligations, Buyer shall commence reporting production and revenues from the Properties effective as of the Closing Date, unless otherwise required by GAAP.

19.6 Further Assurances.

19.6.1 From and after Closing, at the request of Seller but without further consideration, Buyer shall execute and deliver or use Commercially Reasonable Efforts to cause to be executed and delivered such other instruments of conveyance and take such other actions as Seller reasonably may request to more effectively put Seller in possession of any Property that was not intended to be (i) a Property or (ii) conveyed or was conveyed in error by the Parties (including reassignment from Buyer to Seller of any Property that was conveyed in violation of valid preferential purchase rights or material consents to assignment), or to more effectively implement Buyer’s assumption of obligations under Section 12.3. From and after Closing, at the request of Buyer but without further consideration, Seller shall execute and deliver or use Commercially Reasonable Efforts to cause to be executed and delivered such other instruments of conveyance and take such other actions as Buyer reasonably may request to more effectively put Buyer in possession of any Properties conveyed or to have been conveyed to Buyer in accordance with the terms of this Agreement.

19.6.2 Except to the extent constituting Excluded Properties, Seller and Buyer agree that it is the intent of the Parties that Seller assign and convey to Buyer all of the upstream oil and gas assets and midstream assets owned by Seller, which were reflected in the financial information provided to Buyer in the Data Room or were, as of the Effective Time, located in Finney, Grant, Hamilton, Haskell, Kearny, Morton, Seward, ▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ Counties, Kansas.

19.7 Extent of Indemnification. Without limiting or enlarging the scope of the indemnification, defense, release, disclaimer and assumption provisions set forth in this Agreement, to the fullest extent permitted by Law, an indemnified Person shall be entitled to indemnification hereunder in accordance with the terms hereof, regardless of whether the indemnifiable loss giving rise to any such indemnification obligation is the result of the active or passive, sole, concurrent or comparative negligence or gross negligence, strict

HOUSTON 1139976v.13

liability, breach of duty (statutory or otherwise), or other fault or violation of any Law of or by any such indemnified Person, or any pre-existing defect.

19.8 Amendments and Severability. No amendments, waivers or other modifications of this Agreement will be effective or binding on either of the Parties unless the same are in writing, designated as an amendment or modification, and signed by both Parties. The invalidity of any one or more provisions of this Agreement will not affect the validity of this Agreement as a whole, and in case of any such invalidity, this Agreement will be construed as if the invalid provision had not been included herein.

19.9 Successors and Assigns. This Agreement and all of the provisions of this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns, but neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned (by operation of Law or otherwise) prior to the Closing Date by either of the Parties without the prior written consent of the other Party; provided, however, that Buyer may assign this Agreement or any of its rights, interests or obligations hereunder to a wholly-owned Affiliate of such Party. Assignment shall not relieve the assignor of liability hereunder. In the event Buyer or any subsequent (direct or indirect) assignee of Buyer assigns this Agreement or any of its rights or interests under Article 8 of this Purchase Agreement to a Third Party (by operation of law or otherwise), Buyer or its subsequent assignee, as applicable, shall no longer have any rights to make a claim for indemnification under Article 8 following such assignment.

19.10 Headings and Exhibits. The headings contained in this Agreement are inserted for convenience only, shall not constitute a part of this Agreement, and are in no way to be construed as a limitation on the scope of particular sections to which they refer. Information set forth in any Exhibit or Schedule to this Agreement is deemed to have been disclosed for all purposes of this Agreement.

19.11 Governing Law; Consent to Jurisdiction.

19.11.1 This Agreement (including administration of the arbitration provisions set forth in Article 18) shall be governed by and construed and enforced in accordance with the substantive Laws of the State of Texas, without regard to its conflict of laws rules or principles.

19.11.2 The Parties hereby irrevocably submit to the exclusive jurisdiction of the state and federal courts located in ▇▇▇▇▇▇ County, Texas in connection with any dispute arising under or relating to this Agreement, the Operative Documents or any of the transactions contemplated hereby or thereby, that is permitted to be commenced in court, and each Party irrevocably agrees that all Claims in respect of such dispute or proceeding that is permitted to be commenced in court shall be heard and determined exclusively in such courts. The Parties hereby irrevocably waive, to the fullest extent permitted by Law, any objection which they may now or hereafter have to the venue of any dispute arising under or relating to this Agreement or any of the transactions contemplated hereby brought in such court or any defense of inconvenient forum for the maintenance of

HOUSTON 1139976v.13

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.

19.11.3 To the fullest extent permitted by applicable Law, each Party hereby waives any right to a trial by jury of any claim or cause of action based upon or arising out of or related to this Agreement, the other Operative Documents, or the transactions contemplated hereby or thereby, in any action, proceeding or other litigation of any type brought by any of the Parties against any other Party, whether with respect to contract claims, tort claims, or otherwise. The Parties each agree that any such claim or cause of action shall be tried by a court trial without a jury. Without limiting the foregoing, the Parties further agree that their respective right to a trial by jury is waived by operation of this Section 19.11 as to any action, counterclaim or other proceeding which seeks, in whole or in part, to challenge the validity or enforceability of this Agreement or the other Operative Documents or any provision hereof or thereof.

19.11.4 Each Party represents, covenants and warrants that it is subject to service of process in the State of Texas and that it will remain so subject so long as this Agreement remains in effect. If, for any reason, a Party should not be so subject, it hereby designates and appoints, without power of revocation, the Secretary of State of the State of Texas as such Party’s agent upon whom may be served all process, pleadings, notices or other papers which may be served upon such Party as a result of any of its obligations under this Agreement.

19.12 No Partnership Created. It is not the purpose or intention of this Agreement to create (and it should not be construed as creating) a joint venture, partnership or any type of association, and the Parties are not authorized to act as an agent or principal for each other with respect to any matter related hereto. Nothing contained in this Agreement prevents either Buyer or Seller from engaging in any business or purchasing any asset, whether or not in the vicinity of the Properties or in competition with the business of the other.

19.13 Public Announcements. Seller (on behalf of Seller Group) and Buyer (on behalf of Buyer Group) agree not to issue any public statement or press release concerning this Agreement or the transactions contemplated hereby (including price or other terms) without the prior written consent of the other Party, and then only after prior reasonable consultation with the other Party regarding the timing and content of the statement; provided, however, if Seller, on the one hand, or Buyer, on the other is required by Law or the rules of the New York Stock Exchange or another securities exchange to make a public announcement or statement, then the same may be made without the approval of the other Party so long as the other Party is provided reasonable advance notice and with the further understanding that the Party not required to make any such announcement or statement shall have the right to issue its own announcement or statement in connection with or in response to any such required public announcement or statement.

19.14 No Third Party Beneficiaries. Nothing contained in this Agreement entitles any Person other than Seller and Buyer or their permitted successors and assigns to any

HOUSTON 1139976v.13

Claim, remedy or right of any kind whatsoever, except with respect to waivers and indemnities that expressly provide for waivers or indemnification of Buyer Group, Seller Group or another Person, in which case members of such groups and such other Persons are considered third party beneficiaries for the sole purposes of those waiver and indemnity provisions. The immediately preceding sentence notwithstanding, any claim for indemnity or defense under this Agreement shall only be brought and administered by a Party to this Agreement. Each Party may elect to exercise or not exercise the indemnification and defense rights under this Agreement on behalf of any member of the Buyer Group or Seller Group, as applicable, and no member of any such group shall have any rights under this Agreement except to the extent exercised on its or his behalf. For the avoidance of doubt, there will be no third party beneficiaries under this Agreement for breaches of Article 14.

19.15 Waiver of Consumer Rights. As partial consideration for the Parties entering into this Agreement, each Party can and does hereby waive the provisions of the Texas Deceptive Trade Practices Consumer Protection Act, Article 17.41 et. seq., Texas Business and Commerce Code, a law that gives consumers special rights and protection, and all other consumer protection Laws of the State of Texas, or of any other state that may be applicable to this transaction, that may be waived by such Party. It is not the intent of either Party to waive and neither Party does waive any Law or provision thereof that is prohibited by Law from being waived. Each Party represents that it has had an adequate opportunity to review the preceding waiver provision, including the opportunity to submit the same to legal counsel for review and advice and after consultation with an attorney of its own selection voluntarily consents to this waiver, and understands the rights being waived herein.

19.16 Not to be Construed Against Drafter. The Parties acknowledge that they have had an adequate opportunity to review each and every provision contained in this Agreement and to submit the same to legal counsel for review and comment. Based on the foregoing, the Parties agree that the rule of construction that a contract be construed against the drafter, if any, not be applied in the interpretation or construction of this Agreement.

19.17 Possible Exchange. Seller reserves the right to structure the transactions contemplated under the terms of this Agreement as a non-simultaneous like-kind exchange pursuant to Section 1031 of the Code, and its implementing Treasury Regulations. In connection with effectuating a non-simultaneous like-kind exchange, Seller reserves the right, at or prior to the Closing Date or any subsequent closing, to assign its rights under this Agreement to a Qualified Intermediary (as that term is defined in §1.103(k)-1(g)(4) of the Treasury Regulations) or to a Qualified Exchange Accommodation Titleholder (as that term is defined in Revenue Procedure 2000-37) notwithstanding Section 19.9. In addition, should Seller choose to structure a non-simultaneous like-kind exchange, the Parties agree to execute all documents reasonably necessary to effectuate the non-simultaneous like-kind exchange; provided that Buyer shall incur no additional costs, expenses, fees or liabilities as a result of or in connection with the exchange requested by the Seller. Buyer and Seller acknowledge and agree that any assignment of rights under this Agreement to a Qualified Intermediary or an Exchange Accommodation Titleholder shall not release either Party from any of its liabilities and obligations to the other Party under this Agreement, and that neither Party represents to the other Party that any particular Tax treatment will be given to any Party as a result thereof. In no event will either Party be liable to

HOUSTON 1139976v.13

the other for any failure of any transaction to qualify for like-kind treatment under Section 1031 of the Code.

19.18 Schedules. With respect to the representations and warranties of each Party contained in this Agreement, such Party shall have the right until two (2) Business Days prior to the Closing to supplement or modify such Party’s Schedules with respect to any matter hereafter arising or discovered which, if existing or known on the Signing Date, would have been required to be set forth or described in such Party’s Schedule; provided, however that for all purposes of this Agreement, including for purposes of determining whether the conditions set forth in Article 15 have been fulfilled or whether an obligation has arisen under Article VIII, the Schedules shall be deemed to exclude all information contained in any supplement or modification thereto. Certain information set forth in the Schedules is included solely for informational purposes, and the specification of any dollar amount in the representations and warranties contained in this Agreement or the inclusion of any specific item in the Schedules is not intended to imply that such amounts (or higher or lower amounts) are or are not material, and no Party shall use the fact of the setting of such amounts or the fact of the inclusion of any such item in the Schedules in any dispute or controversy between the Parties as to whether any obligation, item, or matter not described herein or included in a Schedule is or is not required to be disclosed or is or is not material for purposes of this Agreement.

19.19 Supplementation of Exhibits. The Parties agree and acknowledge that, Exhibits “A-1” through “A-6” and, “B” to this Agreement may be incorrect, incomplete or subject to revision to include additional or supplemental information prior to the Closing. As soon as practicable, but no later than five (5) Business Days prior to Closing, Seller shall have the right to deliver to Buyer a replacement for Exhibits “A-1” through “A-6” and, “B”; provided, however, such replacement Exhibits must be consistent with Section 19.6.2. Prior to Closing, Buyer and Seller shall reach agreement in writing upon the form and content of each such replacement Exhibits, consent by each Party not to be unreasonably withheld, conditioned or delayed.

19.20 Acknowledgement of Parties; Conspicuousness. EACH PARTY SPECIFICALLY ACKNOWLEDGES AND AGREES (1) THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS HEREOF, AND (2) THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT. EACH PARTY FURTHER AGREES THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY SUCH PROVISIONS OF THIS AGREEMENT ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISIONS OR THAT SUCH PROVISIONS ARE NOT “CONSPICUOUS”. The Parties expressly hereby acknowledge and agree that the provisions contained in this Agreement that are set out in “bold” or in “ALL CAPS” satisfy the requirement of the “express negligence rule” and any other requirement at law or in equity that provisions contained in a contract be conspicuously marked or highlighted.

19.21 Waiver of Compliance. Any failure of Seller, on the one hand, or Buyer, on the other hand, to comply with an obligation, covenant, agreement or condition contained in

HOUSTON 1139976v.13

this Agreement may be expressly waived in writing by the non-failing Party, but, except as otherwise provided in this Agreement, such waiver or failure to insist upon strict compliance shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

19.22 Entire Agreement. The Confidentiality Agreement and this Agreement (including the Exhibits, Schedules, and other documents and ancillary agreements referred to herein, which form a part of this Agreement) embodies the entire agreement and understanding of the Parties in respect of the subject matter contained herein and therein and, except as otherwise provided in Section 17.4, supersedes all prior and contemporaneous negotiations, understandings, letters of intent, and agreements (whether oral or written) between the Parties or their Affiliates relating to the terms of purchase and sale of the Properties and constitute the entire understanding and agreement between the Parties with respect to the sale, assignment and conveyance of the Properties and other transactions contemplated by this Agreement. There are no restrictions, promises, warranties, covenants or undertakings with respect to the transactions contemplated hereby and thereby, other than those expressly set forth or referred to in this Agreement.

19.23 Conflicts. In the event of any conflict between the provisions of this Agreement and the Operative Documents, the provisions of this Agreement shall control. Nothing in the Operative Documents shall be deemed to expand, diminish or otherwise modify the rights or obligations of the Parties as expressed in the provisions of this Agreement.

19.24 Time of Essence. Time is of the essence with respect to all provisions of this Agreement that specify a time for performance; provided, however, that the foregoing shall not be construed to limit or deprive a Party of the benefits of any grace or cure period allowed in this Agreement.

19.25 Counterparts. This Agreement may be executed simultaneously in two or more counterparts (including by means of facsimile or email of a portable document format (pdf) of the signature pages), each of which shall be deemed to be an original, but all of which taken together shall constitute one and the same instrument.

19.26 Financial Statements.

19.26.1 After the Signing Date, Buyer, at Buyer’s expense, may engage Ernst & Young to conduct an audit of the revenues and expenses (and other SEC required disclosures) of Seller attributable to the Properties for a period prior to the Effective Time through the Closing Date, such period to be determined by SEC requirements. In that regard, prior to Closing, Seller shall provide Ernst & Young reasonable access to its records related to the Properties (to the extent such information is available) and personnel of Seller as Ernst & Young may reasonably request in order to conduct such audit at Buyer's sole cost and expense. At all times prior to Closing, Buyer shall cause Ernst & Young not to share with Buyer or its Affiliates information related to, arising out of, or derived from Ernst & Young’s review and audit of Seller’s records. After Closing, Seller shall provide Buyer reasonable access to its records related to the Properties (to the extent such information is available) and personnel of Seller as Buyer may reasonably request to enable Buyer, and its representatives and accountants, at

HOUSTON 1139976v.13

Buyer's sole cost and expense, to audit any records that Buyer reasonably deems necessary. The Parties shall use Commercially Reasonable Efforts to complete such audit prior to April 30, 2012. Notwithstanding the foregoing, (i) Seller shall in no event be required to create new records relating to the Properties and (ii) the access to be provided to Buyer pursuant to this Section shall not interfere with Seller’s ability to prepare its own financial statements or its regular conduct of business and shall be made available during Seller’s normal business hours.

19.26.2 Buyer (on behalf of the Buyer Group and their successors and assigns) releases Seller Group from and shall fully protect, defend, indemnify and hold Seller Group harmless from and against any and all Claims relating to, arising out of, or connected with, directly or indirectly, the preparation or furnishing of any information or records referred to in this Section 19.26, any actions, statements, representations or certifications of Seller’s and its Affiliates’ personnel, accountants, consultants, contractors or auditors with respect to such information or records, or Buyer’s use of any such information or records, the inclusion of any such records or information or matters derived therefrom, in any debt or equity offering documents, filings with any exchange or the U.S. Securities and Exchange Commission, or related materials, regardless of cause or of any negligent acts or omissions (including active or passive, sole, concurrent or comparative negligence or gross negligence), strict liability, breach of duty (statutory or otherwise), violation of Law, or other fault of Seller Group, or any pre-existing defect.
