ARTICLE II
SALE OF PROPERTIES

2.1 Sale and Purchase. On the Closing Date, but effective as of the Effective Time, and upon the terms and conditions of this Agreement: (a) Seller shall sell, assign and convey the Properties to Buyer, and (b) Buyer shall purchase and accept the Properties from Seller; provided, however, that Seller expressly excepts, reserves and retains, unto itself and its Affiliates, successors and assigns, the Excluded Properties.

2.2 Purchase Price. The total consideration for the Properties, subject to adjustments as described below, is (a) the payment by Buyer to Seller of Three Billion Xxx Xxxxxxx Xxxxxxx Xxxxxx Xxxxxx Dollars (US $3,100,000,000) (“Purchase Price”), payable in full (less the amount of the Performance Deposit paid by Buyer to Seller) at Closing in immediately available funds, and (b) Buyer’s assumption of the Assumed Obligations. The Purchase Price shall be adjusted as follows:

2.2.1 increased by the Computed Interest on the Purchase Price for the period from the Effective Time through the earlier to occur of (a) August 31, 2010 and (b) the Closing Date, less the Computed Interest on the Performance Deposit from the date of its receipt by Seller until the earlier to occur of (i) August 31, 2010 and (ii) the Closing Date;

2.2.2 decreased by the amount of Operating Revenues to which Buyer is entitled under Article 6.2 but which are collected and retained by Seller;

2.3 Purchase Price Allocation For Tax purposes, on or before the Closing Date, Buyer and Seller shall agree in writing as to the allocation of the Purchase Price among the Properties under the methodology required pursuant to Section 1060 of the Code (the “Purchase Price Allocation”). If an adjustment to the Purchase Price is made under this Agreement, the Parties shall adjust the Purchase Price Allocation to be consistent with the Adjusted Purchase Price. Seller and Buyer shall report the transactions contemplated hereby on all U.S. federal income tax returns (including Form 8594 and all other information returns and supplements thereto required to be filed by the Parties under Section 1060 of the Code) in a manner consistent with such Purchase Price Allocation.

ARTICLE III
PREFERENTIAL RIGHTS AND CONSENTS TO ASSIGNMENT

3.1 Preferential Rights to Purchase. Seller shall use Buyer’s good faith allocation of the Purchase Price set forth in Exhibit “A” to provide any required preferential right to purchase notifications in connection with the transactions contemplated hereby, using the form of Preferential Purchase Right Notice Letter attached as Exhibit “J”.

3.1.1 If, as of the Closing Date, a holder of a preferential purchase right (“PPR”) has notified Seller that it elects to exercise its PPR with respect to the Properties to which its PPR applies (determined by and in accordance with the agreement in which the PPR arises), then the Properties covered by that PPR will not be sold to the Party originally executing this Agreement as “Buyer” (subject to the remaining provisions in this Article), and the Purchase Price will be reduced by the value allocated to such Properties in Exhibit “A”. Buyer remains obligated to purchase the remainder of the Properties not affected by an exercised PPR or a PPR for which the time to exercise has not expired. Upon the consummation of the sale of any Properties to the holder of such preferential right, any such Properties shall be deemed for all purposes to constitute “Excluded Properties”.

3.1.2 After the Closing, if for any reason the purchase and sale of the Properties covered by the PPR is not or cannot be consummated with the holder of the PPR that exercised its PPR or if the time for exercising the PPR expires without exercise by any holder of the PPR, Seller may so 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 Exhibit “A” (except the Closing Date with respect to such Properties will be the date of assignment of such Properties from Seller to Buyer).

3.1.3 If on the Closing Date any PPR applicable to some Properties has not been waived and the time to elect has not elapsed, Closing with respect to such Properties affected thereby shall proceed. If (i) the holder of a PPR validly exercises its preferential right to purchase after the Closing, or (ii) the Parties inadvertently close on a Property subject to a PPR either without having provided the required notification to the holder of such PPR or without such holder having waived such PPR or the time for such holder to exercise such PPR having expired, and after closing on such Property, the holder of such PPR elects to exercise such PPR, then within ten (10) Business Days of (i) or (ii) above (x) Buyer and Seller shall execute such instruments as reasonably necessary to revoke, extinguish and/or rescind the original assignment of such affected Property(ies) to Buyer and/or re-convey such affected Properties to Seller, as appropriate (each hereinafter a “Rescission”), effective as of the Effective Time, (y) Seller shall cause an amount equal to (1) Buyer’s good faith allocation of the Purchase Price set forth in Exhibit “A” attributable to such affected Property(ies) or, in the case of an affected Property that is not allocated a value in Exhibit “A”, as may be mutually agreed by the Parties; provided that if no such agreement is reached, such matter shall be an Arbitrable Dispute; (2) decreased by the amount of Operating Revenues attributable to such

Properties after the Effective Time that are actually accounted for, collected or retained by Buyer; (3) increased by the Charges attributable to such Properties after the Effective Time that are paid or accounted for by Buyer; and (4) increased by the amount of taxes and assessments attributable to such Properties paid by Buyer, to be paid to Buyer in accordance with wire instructions to be provided by Buyer at least two (2) Business Days prior to the end of such ten (10) Business Day period and (z) any Properties in which the holder of a PPR validly exercises and acquires shall automatically, and without need to amend this Agreement, be deemed to constitute Excluded Properties for all purposes of this Agreement, and the Buyer shall have no further obligations with respect to such Excluded Properties. If for any reason the purchase and sale of such affected Property(ies) covered by the validly exercised PPR contemplated by this Article 3.1.3 is not or cannot be consummated with the holder of the PPR within ninety (90) Days after the Closing, Seller shall so notify Buyer within three (3) Business Days, 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 Buyer’s good faith allocation of the Purchase Price set forth in Exhibit “A” (except “Closing Date” with respect to any such Properties shall mean the date of assignment of such Properties from Seller to Buyer).

3.1.4 Any PPR must be exercised subject to the terms and conditions of this Agreement, including the payment to Seller of a performance deposit in an amount that corresponds to the percentage of the Purchase Price set forth in Article 2.4.

3.2 Consents to Assignment.

3.2.1 If a required consent 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 Exhibit “A” or, in the case of an affected Property that is not allocated a value in Exhibit “A”, as may be mutually agreed by the Parties; provided that if no such agreement is reached prior to Closing, such matter shall be an Arbitrable Dispute. Buyer remains obligated to purchase from Seller the remainder of the Properties that are not subject to such unobtained required consent. If Seller subsequently obtains any required consents 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 Exhibit “A” or otherwise determined by mutual agreement or determined pursuant to the provisions of Article 18 for purposes of the adjustment to the Purchase Price previously made 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).

3.2.2 With respect to Contracts and Other Agreements incident to ownership of or reasonably necessary for the operation of the Properties that require consent to assignment and which consent has not been obtained prior to Closing, Buyer at its option, shall have the right to elect to have this Article 3.2.2 apply with respect thereto, instead of having the affected Property (and the related Contract or Other

Agreement) excluded from this Agreement as provided in Article 3.2.1. If Buyer elects to have this Article 3.2.2 apply to any such Contract or Other Agreement, Seller shall execute and deliver such instruments and take such other actions as Buyer may reasonably request in order to carry out the intent of this Agreement and the transfer of such Contracts or Other Agreements, including the execution of back-to-back agreements to effect the transfer from Seller to Buyer of the benefits and burdens of or on Seller under all such Contracts or Other Agreements under 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 or Other Agreement), to the extent that Seller is unable to transfer or assign such Contract or Other Agreement to Buyer. To the extent that Seller is unable to assign a Contract or Other Agreement with respect to which Seller has elected that this Article 3.2.2 shall apply, Seller shall use commercially reasonable efforts to continue to hold such Contract or Other Agreement for the benefit of Buyer until such time as (x) such Contract or Other Agreement can be assigned to Buyer in accordance with the terms thereof, or (y) the Contract or Other Agreement is terminated in accordance with its terms or otherwise at the direction of Buyer, to the extent such termination does not breach such Contract or Other Agreement.

3.3 Affiliate Consents and Waivers. Each Party shall cause its Affiliates to give any required consents and waive any PPR held by such Affiliates.

ARTICLE IV

4.1 Review of Title Records. Not later than (i) five (5) Business Days after the execution and delivery of the Agreement with respect to the Properties set forth on Schedule 4.1 or (ii) August 2, 2010 with respect to all other Properties, Seller shall make available (during Seller’s regular business hours and at their current location) for Buyer’s review, Records in Seller’s and its Affiliates’ 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.

5.1.1 Any such inspection, including through the performance of Phase I Environmental Site Assessments, shall be conducted in accordance with the terms of the Confidentiality Agreement and subject to any releases or other agreements required by the operator of the Properties. Prior to Closing, Buyer may not operate equipment, conduct testing, sample materials, perform Phase II environmental audits, or conduct invasive activities during such inspection without Seller’s prior written consent, which consent shall not be unreasonably withheld. Buyer shall be responsible for arranging, at its own cost, transportation to and from the Properties. During the time period between the Closing and the Adverse Condition Diligence Review Deadline, Buyer may not conduct testing, sample materials, conduct invasive activities related to environmental conditions or perform Phase II environmental audits without in any case obtaining any applicable Third Party operator’s prior written consent, and without obtaining Seller’s prior written consent, which consent shall not be unreasonably withheld, unless recommended in a Phase I environmental audit or required by applicable Law in which case Seller’s prior written consent will not be required.

5.1.2 Buyer’s access to the Properties shall be at Buyer’s sole risk and expense; and Buyer hereby releases Seller Group from and shall fully indemnify, defend, protect and hold Seller Group harmless from and against any and all Losses and Third Party Claims to the extent arising out of or connected with Buyer’s inspection of the Properties or travel to or from or presence on the Properties in connection with the transactions contemplated by this Agreement.

As soon as reasonably practical (and on an ongoing basis), but no later than one hundred twenty (120) Days after the Closing Date (the “Adverse Condition Diligence Review Deadline”), Buyer shall notify Seller of any conditions that might constitute Alleged Adverse Conditions. Buyer’s notice of such conditions must include (i) a description of each individual condition to which Buyer takes exception (including any and all supporting documentation) and (ii) an estimate of the costs Buyer in good faith attributes to bringing such condition into compliance with applicable Environmental Laws. Seller and Buyer shall meet from time to time to attempt to agree on a resolution of Alleged Adverse Conditions.

5.2.1 If the Parties are unable to agree on resolution of any Alleged Adverse Conditions on or before sixty (60) Days after the Adverse Condition Diligence Review Deadline, Seller has the option, in its sole discretion, to either (a) bring the Alleged Adverse Condition into compliance with Environmental Laws (as in effect as of the Closing Date); or (b) deliver to Buyer an indemnity agreement in favor of Buyer Group, upon terms reasonably acceptable to Buyer, fully releasing Buyer Group from and protecting, defending, indemnifying and holding Buyer Group harmless from and against all Environmental Claims arising from or relating to such Alleged Adverse Condition.

Seller’s remediation of any Alleged Adverse Condition may

not materially interfere with the use of operation of the affected Property. If Seller does not remediate an Alleged Adverse Condition within such period, Buyer shall give Seller written notice of such failure or non-completion and within five (5) Business Days following the earlier to occur of the date that (i) Seller and Buyer agree in writing on the existence and value of the Alleged Adverse Condition or (ii) resolution of any dispute regarding the existence or value of the Alleged Adverse Condition in accordance with the provisions of Article 5.4, Seller shall pay to Buyer an amount equal to the value of such Alleged Adverse Condition, if any, as so agreed or determined.

5.2.3 If an Alleged Adverse Condition can be remediated, the adjustments or payments with respect to that Alleged Adverse Condition shall not exceed the Prudent Cost Response.

5.2.4 Notwithstanding anything contained in this Agreement to the contrary, Buyer shall not be entitled to an adjustment or other remedy relating to any Alleged Adverse Condition unless and until the aggregate value of all Aggregate Transaction Claims exceeds the Deductible, and then only to the extent such Aggregate Transaction Claims exceeds the Deductible; and Buyer shall be solely responsible for and bear all costs and expenses associated with any and all Aggregate Transaction Claims up to the Deductible. No payment shall be due with respect to any Alleged Adverse Condition for which Seller, at its option, delivers to Buyer an indemnity agreement in favor of Buyer in accordance with Article 5.2.1, nor shall any Alleged Adverse Condition for which Seller has indemnified Buyer be included as an Aggregate Transaction Claim.

5.3 Waiver. Buyer (on behalf of Buyer Group and their successors and assigns) waives for all purposes all objections and Claims (whether known or unknown) associated with environmental conditions (including Alleged Adverse Conditions) except for (a) Buyer’s rights with respect to Seller’s indemnity under Article 8.3, (b) Alleged Adverse Conditions Buyer raised to Seller by proper notice within the applicable time period specified in, and as otherwise required by, Article 5.2, and (c) such Alleged Adverse Conditions as are settled by written agreement of the Parties or determined in accordance with Article 5.4.

Except as otherwise provided in the preceding sentence, any Environmental Dispute arbitration proceeding shall be conducted in accordance with Article 18. To the extent that the award of the Environmental Referee with respect to any Alleged Adverse Condition value is not taken into account as an adjustment to the Purchase Price pursuant to Article 6, then within ten (10) Days after the Environmental Referee delivers written notice to Buyer and Seller of the

award with respect to an Alleged Adverse Condition value, and subject to the other terms hereof and after taking into account all previous adjustments to the Purchase Price in accordance with Article 6, (i) Buyer shall pay to Seller the amount, if any, so awarded by the Environmental Referee to Seller and (ii) Seller shall pay to Buyer the amount, if any, so awarded by the Environmental Referee to Buyer.

6.7.1 Seller shall reimburse Buyer for any and all Charges paid by Buyer (to the extent not accounted for in the Final Accounting Settlement or the Transition Agreement) that are attributable to periods prior to the Effective Time, except producing, drilling and overhead charges payable to Seller or its Affiliates and the sum per month specified in Article 6.2.2 which are to be retained by Seller, and

ARTICLE VII
LOSS, CASUALTY AND CONDEMNATION

7.1 Notice of Loss. Seller shall promptly notify Buyer of all instances of Casualty Loss that occur and become known to Seller between the date of this Agreement and Closing.

7.2 Casualty Loss. If, prior to Closing, any Properties are impacted by a Casualty Loss, Seller and Buyer shall meet to attempt to agree on an adjustment to the Purchase Price reflecting the reduction in value of the Properties because of such Casualty Loss. For this purpose “reduction in value” is based on the principle that Seller should generally bear the costs of repairing the Properties to the state existing immediately prior to the Casualty Loss, but if such repair results in equipment or facilities that are newer than or upgraded from that which existed immediately prior to the Casualty Loss, Buyer should bear a portion of such costs as is equitable given the benefit to Buyer of such newer or upgraded equipment or facilities. No adjustment associated with a Casualty Loss will exceed the reasonable value claimed by the Buyer in the applicable claim to Seller of such Casualty Loss.

7.2.1 If the Parties are unable to agree on resolution of a Casualty Loss, the Parties shall Close with the Purchase Price being decreased by the arithmetic average of the good faith estimates of the reduction in value associated with such Casualty Loss by both Buyer and Seller; provided, however, that within thirty (30) Days after the Closing Date, either Party may initiate binding arbitration in accordance with Article 18 to resolve the dispute. Any claim with respect to a Casualty Loss not referred to arbitration within thirty (30) Days following Closing (or, with respect to any Casualty Loss for which Seller provides notice that it will continue attempting to cure after Closing, within thirty (30) Days after the one hundred eighty (180) Day period cure period following Closing has expired) shall be deemed waived by Buyer for all purposes.

7.2.2 Seller shall retain any and all insurance proceeds and other payments associated with or attributable to any Casualty Losses.

(f) any Claims relating to the Properties operated by Seller and arising out of the gross negligence or willful misconduct of the Seller or its Affiliates; and

(g) any Claims or obligations relating to Seller’s employees for which Seller has agreed to be responsible pursuant to the provisions of the Transition Agreement.

Claims under this Article 8.6 may be made whether or not a Claim also could be asserted under Articles 8.2 or 8.3, and Claims under this Article 8.6 are not subject to any of the limitations set forth in Article 8.7 or elsewhere in this Agreement and survive indefinitely.

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

(a) any Claim under Article 8.2 or 8.3, if Buyer has not provided Seller with a Claim Notice within twenty-four (24) months from and after Closing with respect to such Claim (other than (i) Claims under Article 8.2(b) with respect to the breach of Article 10.1.23 for which a Claim Notice must be given within seventy-two (72) months from and after Closing and (ii) any Claim under (A) Article 8.2(b) with respect to the breach of any of the Seller’s covenants in Articles 3, 6, 17, 19 or Exhibit “K” or relating to a breach of Article 10.1.6 and (B) Article 8.3(b), each of which shall survive indefinitely); and

(b) any and all Claims (other than any Claim under Article 8.2(b) with respect to the breach of any covenants set forth in Articles 3, 6, 17, 19 and Exhibit “K” or relating to the breach of any representation or warranty in Article 10.1.6 or Article 10.1.23, for which there shall be no threshold or deductible hereunder) in the aggregate up to three percent (3%) of the Purchase Price.

Seller shall not collectively be required to indemnify Buyer under Articles 8.2 and 8.3 for aggregate damages in excess of the Purchase Price.

In calculating the foregoing deductible amounts set forth in this Article 8.7, any dollar or materiality qualifiers in the representations and warranties shall be disregarded. Notwithstanding anything in this Agreement to the contrary, with respect to an Alleged Adverse Condition and/or any Claim relating thereto, in determining whether Buyer is entitled to a remedy for such Alleged Adverse Condition and/or any Claim relating thereto, the threshold amounts with respect thereto shall not be applied more than once.

8.8 Notice of Claims. If a Claim is asserted against a Party for which the other Party may have an obligation of indemnity and defense (whether under this Article 8 or any other provision of this Agreement), the Party seeking indemnification (“Indemnified Party”) shall give the Party from which the Indemnified Party seeks indemnification (“Indemnifying Party”) prompt written notice of the Claim, setting forth the particulars associated with the

Claim (including a copy of the written Claim, if any) as then known by the Indemnified Party (“Claim Notice”).

8.9 Defense of Claims. Within thirty (30) Days after the Indemnifying Party receives a Claim Notice, the Indemnifying Party shall notify the Indemnified Party whether or not the Indemnifying Party will assume responsibility for defense and payment of the Claim. The Indemnified Party is authorized, prior to and during such thirty (30) Day period, to file any motion, pleading or other answer that it deems necessary or appropriate to protect its interests, or those of the Indemnifying Party, and that is not prejudicial to the Indemnifying Party. If the Indemnifying Party elects not to assume responsibility for defense and payment of the Claim, the Indemnified Party may defend against, or enter into any settlement with respect to, the Claim as it deems appropriate without relieving the Indemnifying Party of any indemnification obligations the Indemnifying Party may have with respect to such Claim. The Indemnifying Party’s failure to respond in writing to a Claim Notice within the thirty (30) Day period shall be deemed an election by the Indemnifying Party not to assume responsibility for defense and payment of the Claim. If the Indemnifying Party elects to assume responsibility for defense and payment of the Claim: (a) the Indemnifying Party shall defend the Indemnified Party against the Claim with counsel of the Indemnifying Party’s choice (reasonably acceptable to Indemnified Party which shall cooperate with the Indemnifying Party in all reasonable respects in such defense), (b) the Indemnifying Party shall pay any judgment entered or settlement with respect to such Claim, (c) the Indemnifying Party shall not consent to entry of any judgment or enter into any settlement with respect to the Claim that (i) does not include a provision whereby the plaintiff or claimant in the matter releases the Indemnified Party from all liability with respect to the Claim or (ii) contains terms that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity), and (d) the Indemnified Party shall not consent to entry of any judgment or enter into any settlement with respect to the Claim without the Indemnifying Party’s prior written consent. In all instances the Indemnified Party may employ separate counsel and participate in defense of a Claim, but the Indemnified Party shall bear all fees and expenses of counsel employed by the Indemnified Party.

8.10 Waiver of Certain Damages. Each Party irrevocably waives and agrees not to seek indirect, consequential, punitive or exemplary damages of any kind in connection with any dispute arising out of or related to this Agreement or breach hereof. For the avoidance of doubt, this Article 8.10 does not diminish or otherwise affect the Parties’ rights and obligations to be indemnified against, and provide indemnity for, Claims under any indemnities in this Agreement.

8.11 Exclusive Remedy. Except for remedies that cannot be waived as a matter of Law, if Closing occurs, the indemnities set forth in this Agreement shall be the exclusive remedy for breach of any representation, warranty or covenant set forth in this Agreement; provided, however, nothing in this Article 8.11 shall be deemed to affect any Person’s right to equitable relief (including specific performance) for breach of a covenant set forth in this Agreement.

9.2 Disclaimer of Statements and Information. Except for the representations and warranties of Seller set forth in this Agreement and the disclosures relating thereto, Seller expressly disclaims any and all liability and responsibility for and associated with the quality, accuracy, completeness or materiality of information, data and materials shown to or furnished (electronically, orally, in writing or any other medium and whether or not shown or furnished before or after execution of this Agreement) to Buyer Group and associated with the Properties or the transactions contemplated by this Agreement; and Buyer (on behalf of Buyer Group and their successors and assigns) irrevocably waives any and all claims they may have against Seller Group associated with the same.

Buyer is sophisticated in evaluation, purchase, ownership and operation of oil and gas properties and related facilities similar to the Properties, and in making its decision to enter into this Agreement and to consummate the transactions contemplated herein, Buyer (a) relied solely on its own independent investigation and evaluation of the Properties and the advice of its engineers, contractors, geological and geophysical advisors, lawyers and accountants and not on any comments, statements, reports, projections or other documents or materials provided by or for Seller or its agents, whether before or after execution of this Agreement, and (b) satisfied itself as to the environmental, physical and other condition of, and contractual arrangements affecting, the Properties.

ARTICLE XII
ADDITIONAL COVENANTS

12.1 Subsequent Operations. Seller makes no representations or warranties to Buyer as to transferability or assignability of operatorship of any Properties that Seller currently operates. Rights and obligations associated with operatorship of the Properties are governed by operating and similar agreements covering the Properties and will be decided in accordance with the terms of such agreements.

12.2 Buyer’s Assumption of Obligations. If Closing occurs, and subject only to Seller’s indemnities in Articles 5.2, 8.2, 8.3 and 8.6, and except for other matters that are Seller’s or its Affiliate’s express obligations under this Agreement, Buyer hereby assumes, shall pay and shall timely perform and discharge all of Seller’s duties and obligations associated with the Properties arising prior to, on or after the Closing (including any and all contractual duties and obligations arising therefrom) (collectively, the “Assumed Obligations”), and in fulfilling these obligations, Buyer shall comply with all Laws.

12.3 Asbestos and NORM. The Properties may currently or have in the past contained asbestos and NORM, and special procedures associated with assessment, remediation, removal, transportation or disposal of asbestos and NORM may be necessary, and Buyer acknowledges and agrees as follows from and after Closing.

12.3.1 Except with respect to a breach by Seller of any of its representations or warranties contained in Article 10, as limited by Article 8, Buyer accepts sole responsibility for and agrees to pay any and all costs and expenses associated with assessment, remediation, removal, transportation and disposal of asbestos and NORM associated with the Properties, and may not claim the fact that assessment, remediation, removal, transportation or disposal of asbestos and NORM are not complete or that additional costs and expenses are required in connection with assessment, remediation, removal, transportation or disposal of asbestos and NORM as an Alleged Adverse Condition or the basis for any other redress against Seller or its Affiliates, and Buyer (on behalf of Buyer Group and their successors and assigns) irrevocably waives any and all Losses and Third Party Claims they may have against Seller Group associated with the same; and

12.3.2 Except with respect to a breach by Seller of any of its representations or warranties contained in Article 10, as limited by Article 8, Buyer releases Seller Group from and shall fully protect, defend, indemnify, and hold Seller Group harmless from and against any and all Losses and Third Party Claims relating to, arising out of, or connected with, directly or indirectly, the assessment, remediation, removal, transportation and disposal of asbestos and NORM associated with the Properties, no matter whether arising before, on or after the Effective Time. This indemnity and defense obligation will apply regardless of cause or of any negligent acts or omissions (including sole negligence, concurrent negligence or strict liability), breach of duty (statutory or otherwise), violation of Law or other fault of Seller Group, or any pre-existing defect. For the removal of doubt, Buyer’s release under this Article 12.3 does not prevent Buyer from asserting

the existence of an Alleged Adverse Condition under Article 5.2 for asbestos or NORM that is, as of a date prior to Closing, in a condition that violates existing Laws. The preceding sentence shall in no way expand Buyer’s rights under Article 5.2 or diminish Buyer’s waiver contained in Article 5.3.

12.4 Plugging and Abandonment. The Properties may contain xxxxx and facilities that have been shut in or temporarily or permanently abandoned including such xxxxx as are listed on Schedule 12.4, and Buyer acknowledges and agrees as follows from and after Closing:

12.4.1 Except with respect to a breach by Seller of any of its representations or warranties contained in Article 10, as limited by Article 8, Buyer hereby expressly assumes and accepts sole and exclusive responsibility for and agrees to pay all costs and expenses associated with Plugging and Abandonment of all xxxxx and facilities associated with the Properties (whether or not listed on Schedule 12.4), and may not claim the fact that Plugging and Abandonment operations are not complete or that additional costs and expenses are required to complete Plugging and Abandonment operations as an Alleged Adverse Condition or the basis for any other redress against Seller or its Affiliates, and Buyer (on behalf of Buyer Group and their successors and assigns) irrevocably waives any and all Losses and Third Party Claims they may have against Seller Group associated with the same; and

12.4.2 Except with respect to a breach by Seller of any of its representations or warranties contained in Article 10, as limited by Article 8, Buyer releases Seller Group from and shall fully protect, defend, indemnify, and hold Seller Group harmless from and against any and all Losses and Third Party Claims relating to, arising out of, or connected with, directly or indirectly, Plugging and Abandonment operations, no matter whether arising before, on or after the Effective Time. This indemnity and defense obligation will apply regardless of cause or of any negligent acts or omissions (including sole negligence, concurrent negligence or strict liability), breach of duty (statutory or otherwise), violation of Law, or other fault of Seller Group, or any pre-existing defect. For the removal of doubt, Buyer’s release under this Article 12.4 does not prevent Buyer from asserting the existence of an Alleged Adverse Condition under Article 5.2 for any condition that, as of a date prior to Closing, violates existing Laws with respect to Plugging and Abandonment operations. The preceding sentence shall in no way expand Buyer’s rights under Article 5.2 or diminish Buyer’s waiver contained in Article 5.3.

12.5 Process Safety Management. Buyer acknowledges that Process Safety Management is an ongoing process, and Buyer acknowledges and agrees as follows from and after Closing:

(a) Except with respect to a breach by Seller of any of its representations or warranties contained in Article 10, as limited by Article 8, Buyer accepts sole responsibility for and agrees to pay all costs and expenses associated with Process Safety Management associated with the Properties (including identification,

evaluation and remediation), and may not claim the fact that the Process Safety Management is not complete or that additional costs and expenses are required to comply with or complete Process Safety Management as an Alleged Adverse Condition, or the basis for any other redress against Seller, and Buyer (on behalf of Buyer Group and their successors and assigns) irrevocably waives any and all claims they may have against Seller Group associated with the same; and

(b) Except with respect to a breach by Seller of any of its representations or warranties contained in Article 10, as limited by Article 8, Buyer 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, Process Safety Management associated with the Properties, no matter whether arising before or after the Effective Time. This indemnity and defense obligation will apply regardless of cause or of any negligent acts or omissions (including sole negligence, concurrent negligence or strict liability), breach of duty (statutory or otherwise), violation of Law, or other fault of Seller Group, or any pre-existing defect. For the removal of doubt, Buyer’s release under this Article 12.5 does not prevent Buyer from asserting the existence of an Alleged Adverse Condition under Article 5.2 for any condition that, as of a date prior to Closing, violates existing Laws with respect to Process Safety Management. The preceding sentence shall in no way expand Buyer’s rights under Article 5.2 or diminish Buyer’s waiver contained in Article 5.3.

12.6 Imbalances. Imbalances may exist as of the Effective Time. If Closing occurs, all Imbalances (whether for over-production or over-deliveries by Seller or under-production or under-deliveries by Seller) will pass to Buyer as of the Effective Time, and Buyer thereupon shall be entitled to all rights and shall assume all obligations with respect to any and all such Imbalances. There shall be no amounts paid to or by either Party to the other as a Purchase Price adjustment, as part of the Final Accounting Settlement or otherwise, based on Imbalances. Subject to Article 8, if Closing occurs:

12.6.1 Buyer accepts sole responsibility for and agrees to pay all costs and expenses, if any, associated with Imbalances, and Buyer (on behalf of Buyer Group and their successors and assigns) irrevocably waives any and all claims they may have against Seller Group associated with the same; and

12.6.2 Buyer releases Seller Group from and shall fully protect, defend, indemnify and hold Seller Group harmless from and against any and all Losses and Third Party Claims relating to, arising out of, or connected with, directly or indirectly, Imbalances, no matter whether arising before, on or after the Effective Time.

12.7 Suspense Funds. Buyer acknowledges that Suspense Funds may exist as of the Effective Time. Seller shall transfer at Closing any Suspense Funds held by Seller as operator of any Properties and the obligations with respect thereto to Buyer. This transfer shall be accounted for in the Final Accounting Statement. Subject to Article 6 and Article 8, if Closing occurs:

12.7.1 Buyer accepts sole responsibility for and agrees to pay all costs and expenses associated with the Suspense Funds, and Buyer (on behalf of Buyer Group and their successors and assigns) irrevocably waives any and all claims they may have against Seller Group associated with the same; and

12.7.2 Buyer releases Seller Group from and shall fully protect, defend, indemnify and hold Seller Group harmless from and against any and all Losses and Third Party Claims relating to, arising out of, or connected with, directly or indirectly, the Suspense Funds, no matter whether arising before, on or after the Effective Time.

12.8 Sales Tax. The Parties agree that this sale is an occasional sale of assets by Seller in which it does not trade in the ordinary course of business. The Parties shall take commercially reasonable actions to assert and establish the occasional sale exemption from Sales Tax associated with the transactions contemplated hereby. If Sales Tax is due and owing as a result of Seller’s transfer of the Properties to Buyer, Buyer shall be solely responsible and liable for any and all such Sales Tax. Before the Closing Date, Buyer and Seller shall agree on the value of the tangible personal property being transferred and Buyer shall provide Seller with documentation detailing the basis for Buyer’s allocation of the Purchase Price to any such Properties that are subject to Sales Tax. Buyer shall provide Seller with an exemption certificate for any tangible personal property included in the Properties for which it claims a Sales Tax exemption. Seller shall invoice, and Buyer shall pay, any Sales Tax on Buyer’s acquisition of all nonexempt tangible personal property and Seller shall remit the Sales Tax to the applicable governmental entity or authority. If Seller is later required to pay any additional Sales Tax, interest, or penalty thereon, 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 (including Article 6 or Article 8), Buyer releases Seller Group from and shall fully protect, defend, indemnify and hold Seller Group harmless from and against any and all Losses and Third Party 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 Properties to Buyer.

12.9 Guaranty Agreement and First Amendment to Deed of Guarantee and Indemnity.

12.9.2 Seller has caused its ultimate parent company or an Affiliate of Seller (who is acceptable to Seller) to execute and deliver the Guaranty Agreement in the form of Exhibit “I-2” simultaneously with the execution of this Agreement.

12.9.3 Each of Seller and Buyer has caused BP Exploration Operating Company Limited and Apache Corporation, respectively, to execute and deliver the First Amendment to Deed of Guarantee and Indemnity simultaneously with the execution of this Agreement.

12.10 Transition Agreement. Buyer and Seller shall execute and deliver the Transition Agreement at Closing.

12.11 Seismic Data. Notwithstanding anything in this Agreement to the contrary, Buyer is responsible for obtaining any necessary consents to Seller’s assignment of any Third Party Seismic Data licenses or other agreements or for Buyer to enter into new licenses or other agreements, in each case as may be needed to permit Buyer to continue to utilize any Third Party Seismic Data covering the Properties after the Closing Date. Seller shall reasonably assist Buyer in contacting the relevant Third Parties, but Buyer shall be solely responsible for and shall bear all costs and transfer and other fees required to obtain assignments or new licenses or other agreements in connection with Third Party Seismic Data. With respect to any of Seller’s wholly-owned seismic data pertaining to the Properties, Buyer and Seller shall execute and deliver the Seismic License at Closing.

12.12.1 Without the consent of Buyer (which shall not be unreasonably withheld or delayed), during the Interim Period, Seller shall not, with respect to the Properties:

(a) except with respect to matters indemnified by Seller that are referenced in Exhibit “C”, waive, compromise or settle any right or claim which reasonably would be expected to have a Material Adverse Effect;

(b) incur any obligation in excess of $500,000 with respect to the Properties for which Buyer would be responsible after Closing, other than in connection with transactions in the normal, usual and customary manner, of a nature and in an amount consistent with past practices employed by Seller with respect to the Properties and/or in connection with situations believed in good faith by Seller to constitute an emergency (in which case Seller’s obligation is limited to notifying Buyer as soon as reasonably practicable of such emergency and obligations);

(c) encumber, sell, lease, or otherwise dispose of any of the Properties having a value in excess of $500,000 (excluding sales of hydrocarbons therefrom), except to the extent replaced by equivalent property or to the extent used, consumed or abandoned in the normal operations of Seller’s business; or

(d) enter into a contract or commitment for any capital expenditure or acquisition or construction of fixed assets in either case for which Buyer would be responsible after Closing in an amount individually in excess of $500,000, except in connection with situations believed in good faith by Seller to constitute an emergency (in which case Seller’s obligation is limited to notifying Buyer as soon as reasonably practicable of such emergency and obligations).

12.12.2 Regardless of whether all of the operations conducted by Seller during the Interim Period with respect to any of the Properties have been fully

completed by Seller prior to Closing, upon Closing Buyer shall assume full responsibility for the completion of all such operations applicable to the Properties, subject, however, to the terms of the Transition Agreement during the Transition Period.

12.12.3 Buyer acknowledges Seller owns undivided interests in certain of the Properties and that Seller does not operate all of the Properties, and Buyer agrees that the acts or omissions of Third Party working interests owners (including Third Party operators) shall not constitute a breach of the provisions of this Article 12.12, nor shall any action required by a vote of working interest owners constitute such a breach so long as Seller has voted its interest in a manner that complies with the provisions of this Article 12.12. Furthermore. Seller shall not be deemed or held to be in breach of any of Seller’s representations, warranties, covenants or other agreements contained in this Agreement to the extent that any such breach arises out of or in connection with the actions of Buyer or Buyer’s Affiliates as operators or co-owners of any of the Properties prior to the Closing.

12.13 Consents to Assign. Prior to the Closing Date, Seller shall attempt to obtain consents necessary to assign the Properties to Buyer at Closing.

12.14 Notification of Breaches. Until Closing:

12.14.1 Buyer shall notify Seller promptly upon Buyer’s knowledge that any of Seller’s or Buyer’s representations or warranties in this Agreement are untrue in any material respect or will be untrue in any material respect as of the Closing Date or that any covenant or agreement to be performed or observed by Seller prior to or on the Closing Date has not been so performed or observed in any material respect or that any title defect or noncompliance with any Environmental Law exists.

12.14.2 Seller shall notify Buyer promptly upon Seller’s knowledge that any of Seller’s or Buyer’s representations or warranties in this Agreement are untrue in any material respect or will be untrue in any material respect as of the Closing Date or that any covenant or agreement to be performed or observed by Buyer prior to or on the Closing Date has not been so performed or observed in a material respect.

12.14.3 If any of Buyer’s or Seller’s representations or warranties are untrue or will become untrue in any material respect between the date of execution of this Agreement and the Closing Date, or if any of Buyer’s or Seller’s covenants or agreements to be performed or observed prior to or on the Closing Date shall not have been so performed or observed in any material respect, but if such breach of representation, warranty, covenant or agreement shall (if curable) be cured by the Closing, then such breach shall be considered not to have occurred for all purposes of this Agreement.

12.15 Third Party-Owned Software. Buyer shall be responsible for the purchase of all Third Party-Owned Software that is needed or is appropriate for Buyer’s operation of the Properties as currently operated by Seller. Seller will use reasonable efforts to procure for Buyer the rights (including seeking and obtaining relevant vendor consents) to access

and use (or permit Seller to access and use on Buyer’s behalf) all Third Party-Owned Software during the Transition Period only, and Buyer shall bear all costs and fees, if any, to procure such consents and shall reimburse Seller in the Final Accounting Settlement for any such costs or fees incurred by Seller in connection therewith. Buyer acknowledges that Buyer’s rights to access and use Third Party-Owned Software under Third Party consents so procured by Seller will expire at the end of the Transition Period, and Buyer agrees to obtain its own licenses for all Third Party-Owned Software that Buyer deems necessary or appropriate in connection with the operation of the Properties after the Transition Period. Upon termination of the Transition Period, Buyer shall certify to Seller in writing that all Third Party-Owned Software for which consents were obtained for it by Seller either has been de-installed or have been licensed by Buyer from the applicable vendor. Seller shall have the right to confirm, at Seller’s expense, that post-Transition Period use by Buyer of all Third Party-Owned Software has either ceased or continues under license(s) Buyer has acquired from the applicable vendors.

12.16 Financial Statements. Both prior to and after the Closing, Seller shall provide Buyer with access (upon reasonable notice and during normal business hours ) to (i) information reasonably requested by Buyer from Seller’s operating and financial Records relating primarily to the Properties for the fiscal years ended December 31, 2008 and December 31, 2009 which were previously made available to Seller’s auditors for purposes of preparing BP North American Gas Strategic Performance Unit’s (“NAG SPU”) annual audited and quarterly reviewed financial statements for those years with respect to the Properties and (ii) information reasonably requested by Buyer from NAG SPU’s corresponding records for any completed fiscal quarter for the fiscal year to be ended December 31, 2010 prior to the Closing, including (in each case) Records reasonably requested with respect to oil and natural gas reserves and production and direct lease operating costs with respect to each of the Properties and the gross revenues from each of the Properties and such other information relating to the Properties as Buyer may reasonably request in order for Buyer to prepare financial statements for the year ended December 31, 2009 and periods ended June 30, 2010, in each case to the extent necessary to be included by Buyer in any filings under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) with respect to or as a result of the transactions contemplated by this Agreement (the “SEC Basis Financial Statements”) (it being acknowledged that Seller shall not be required to prepare any pro formas and forward-looking statements).

Seller shall reasonably cooperate with the Buyer’s independent public accountants in the preparation, audit and/or review of the SEC Basis Financial Statements so that Buyer may file the SEC Basis Financial Statements within the time period required by the Exchange Act, which cooperation will include the delivery of one or more customary representation letters from Seller to such independent public accountants as may be

reasonably required by such independent public accountants to perform an audit in accordance with generally accepted auditing standards or a review in accordance with AICPA standards and to render an opinion acceptable to the SEC with respect to the audit or review of the SEC Basis Financial Statements, it being understood that such representation letters shall acknowledge (i) Seller’s use of estimates and allocations in the preparation of the SEC Basis Financial Statements, and (ii) Seller’s belief that the SEC Basis Financial Statements represent the financial conditions and results of operations of the Properties, and that such estimates and allocations were made on a reasonable basis. The cost incurred by Seller and its Affiliates in providing the financial Records (including fees of accountants) to Buyer and assisting Buyer as provided in this Article shall be borne by Buyer. Buyer releases Seller Group from and shall fully protect, defend, indemnify and hold Seller Group harmless from and against any and all claims, liabilities, losses or damages (including costs of investigation and attorneys’ and experts’ fees and expenses) relating to, arising out of, or connected with, directly or indirectly, the preparation or furnishing of any such records to Buyer, any actions, representations or certifications of Seller’s and its Affiliates’ personnel or auditors with respect to the information contained in such Records, or Buyer’s use of the information contained in such Records, the inclusion of such financial Records in any debt or equity offering documents or related materials, regardless of cause or of any negligent acts or omissions (including sole negligence, concurrent negligence or strict liability), breach of duty (statutory or otherwise), violation of Law, or other fault of Seller Group, or any pre-existing defect.

If the Parties are unable to agree by that date, Seller’s good faith estimate shall be used to determine the Adjusted Purchase Price to be used at Closing. If the Closing Payment is a positive number, such amount shall constitute the dollar amount to be paid by Buyer to Seller at Closing pursuant to Article 16.3.1. If the Closing Payment is a negative number, the absolute value of such amount shall constitute the dollar amount to be paid by Seller to Buyer pursuant to Article 16.2.1. Seller or Buyer, as applicable, also shall provide to the other Party wiring instructions designating the account(s) to which Buyer or Seller, as applicable, shall deliver the Closing Payment. Closing shall be held on the Closing Date in Seller’s office at 000 XxxxXxxx Xxxx Xxxxxxxxx, Xxxxxxx, Xxxxx 00000 or such other place as Seller may notify Buyer before the Closing Date.

ARTICLE XVII
TERMINATION

17.1 Grounds for Termination. This Agreement may be terminated (except for the individual provisions specifically referenced in Article 17.2 below) at any time prior to Closing (unless another date is stated below):

17.1.1 by the Parties’ mutual written agreement;

17.1.2 by either Party, if consummation of the transactions contemplated by this Agreement would violate any non-appealable final order, decree or judgment of any state or federal court or agency enjoining, restraining, prohibiting or awarding substantial damages in connection with (a) Seller’s proposed sale of Properties to Buyer, or (b) consummation of the transactions contemplated by this Agreement;

17.1.3 by Seller, if Buyer refuses or fails to fulfill its obligations under Article 2.4, without necessity of notice or right to cure;

17.1.4 by either Party, if at any time prior to the Closing Date, such Party becomes aware that any condition precedent to such Party’s obligation to Close cannot be satisfied prior to the Closing Date, provided, however, that the terminating Party shall have given the other Party at least five (5) Business Days (“cure period”) 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;

17.1.5 notwithstanding anything contained in this Agreement to the contrary, by the Seller or Buyer, if Closing has not occurred on or before October 29, 2010 (unless such date is extended by mutual agreement of the Parties); provided, however, that no Party shall have the right to terminate this Agreement pursuant to this Article 17.1.5 if such Party is at such time in material breach of any provision of this Agreement; or

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

17.2 Effect of Termination; Failure to Close. Except as otherwise provided in this Article 17.2, if this Agreement is terminated in accordance with Article 17.1, such termination is without liability to either Party, except performance of obligations in this Article 17.2, Articles 5.1.2, 17.3, 17.4, 18.1, 18.2, 19.1, 19.3, 19.7, 19.8, 19.10, 19.12, 19.13, 19.14, 19.15, 19.16, 19.17 and 19.20, all of which provisions survive termination of this Agreement. If Closing does not occur, Seller shall on the earlier of (i) November 3, 2010 or (ii) within three (3) Business Days after termination of this Agreement, refund the Performance Deposit together with Computed Interest thereon through the end of the Day immediately preceding the date of such refund to Buyer unless Closing did not occur because of Buyer’s material breach of this

Agreement or Buyer’s failure or refusal to Close that is not permitted by the terms of this Agreement. If Closing does not occur because of Buyer’s material breach of this Agreement or Buyer’s failure or refusal to Close that is not permitted by the terms of this Agreement, Seller shall on the earlier of (i) November 3, 2010 or (ii) within three (3) Business Days after termination of this Agreement, refund to Buyer an amount equal to (i) the Performance Deposit together with Computed Interest thereon through the end of the Day immediately preceding the date of such refund minus (ii) an amount equal to five percent (5%) of the Purchase Price together with Computed Interest thereon from July 30, 2010 through the end of the Day immediately preceding the date of such refund (the “Reverse Breakup Fee”). Seller’s retention of the Reverse Breakup Fee shall constitute liquidated damages and not a penalty. Each Party agrees that notwithstanding anything in this Agreement to the contrary, in the event that the Reverse Breakup Fee shall be retained by Seller in accordance with this Article 17.2, the payment of such Reverse Breakup Fee shall be the sole and exclusive remedy of any member of the Seller Group against any member of the Buyer Group, and in no event will any member of the Seller Group seek to recover any other money damages or seek any other remedy based on a claim at law or in equity with respect to (1) any loss suffered, directly or indirectly, as a result of the failure of the transactions contemplated hereby to be consummated, (2) the termination of this Agreement, (3) any liabilities or obligations arising under this Agreement, or (4) any claims or actions arising out of or relating to any breach, termination or failure of or under this Agreement, and no member of the Buyer Group shall have any further liability or obligation to any member of the Seller Group relating to or arising out of this Agreement or the transactions contemplated hereby. The provisions for payment of the Reverse Breakup Fee as liquidated damages in this Article 17.2 have been included because, in the event of termination of this Agreement as described in Article 17.2, both Buyer and Seller agree that the actual damages that would be incurred by Seller are reasonably expected to approximate the amount of the Reverse Breakup Fee 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 Reverse Breakup Fee.

17.3 Dispute over Right to Terminate. If there is a dispute between the Parties over the right of a Party to terminate this Agreement, Closing shall not occur on the Closing Date, and the Party that disputes the right of the other Party to terminate is entitled, within thirty (30) Business Days after the Closing Date, to initiate litigation to resolve the dispute. If the Party that disputes the other Party’s right to terminate this Agreement does not initiate litigation within the thirty (30) Business 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 Reverse Breakup Fee together with any interest earned thereon pursuant to Article 17.2), and the Party that disputes or has a right to dispute 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. Notwithstanding the termination of this Agreement or any other provision of this Agreement to the contrary, the terms of the Confidentiality Agreement remain in full force and effect, provided that if and when Closing occurs and

effective on the Closing Date, the Confidentiality Agreement shall terminate to the extent (and only to the extent) it applies to the Properties conveyed at Closing.

ARTICLE XVIII
ARBITRATION

18.1 Friendly Consultation. 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.

18.2 Arbitration.

18.2.1 The Parties shall attempt to resolve any Arbitrable Dispute promptly by negotiation between representatives who have authority to settle the controversy. Either Party may give the other Party written notice of any Arbitrable Dispute not resolved in the normal course of business. Within thirty (30) Days after delivery of the notice, the receiving Party shall submit to the other a written response. The notice and response shall include (a) a statement of that Party’s position and a summary of arguments supporting that position, and (b) the name and title of that Party’s representative and of any other Person who will accompany the representative. Within thirty (30) Days after delivery of the initial notice, the executives of both Parties 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 shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

18.2.2 If an Arbitrable Dispute has not been resolved within sixty (60) Days after delivery of the initial notice set forth in Article 18.2.1, or if the Parties failed to meet within thirty (30) Days after delivery of such notice, the Parties shall endeavor to settle the dispute by mediation under the AAA Mediation Procedure then currently in effect. Either Party may ask AAA to select a mediator or the Parties may mutually agree on a mediator.

18.2.3 If any Arbitrable Dispute has not been resolved within sixty (60) Days after a Party initially asked the AAA to select a mediator pursuant to Article 18.2.2, then, at the request of either Party, such Arbitrable Dispute shall be submitted to binding arbitration in accordance with the AAA Commercial Arbitration Rules then in effect (the “AAA Rules”).

18.2.4 Except as otherwise provided in Article 5.4 any arbitration hereunder will be conducted before a panel that shall consist of two (2) Party-appointed arbitrators, one (1) appointed by Seller and one (1) appointed by Buyer and a third neutral arbitrator who shall chair the panel. No arbitrator may be a current or former officer, director, employee or consultant of, or other person who has had a business or personal relationship with, a Party or of any of its Affiliates. Each arbitrator must be an attorney

licensed in the State of Texas and must have not less than seven (7) years of experience in the U.S. oil and gas industry. The third arbitrator (if applicable) shall be selected as provided in the AAA Rules.

18.2.5 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. If there is any inconsistency between this Article 18 and the AAA Rules or the Federal Arbitration Act, this Article 18 shall control. The arbitrators may, in their discretion, limit or expand discovery in any arbitration proceeding. The arbitrators’ award shall be 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 (a) the terms and conditions of this Agreement and (b) 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. 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 punitive damages or any other damages expressly waived in Article 8.10.

18.2.6 The arbitration shall take place in Houston, Texas.

18.2.7 The arbitration panel 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 attorney’s fees and expert fees, as determined by the arbitration panel considering those factors mentioned in the first sentence of this Article 18.2.7, incurred in connection with such Party’s preparation for and participation in the arbitration.

18.2.8 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 American Arbitration Association.

18.2.9 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 arbitral tribunal shall have full authority to grant provisional remedies and to direct the Parties to request that any court modify or vacate any temporary or preliminary relief issued by such court.

18.2.10 Before a request to arbitrate under Article 18.2.3 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, they 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.

ARTICLE XIX

Buyer shall maintain the Records received from Seller for five (5) years after the Closing Date and afford Seller full access to the Records and a right to copy the Records at Seller’s expense as reasonably requested by Seller. 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 by Buyer for indemnity or breach of Seller’s representations, warranties or covenants 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.

19.5 Further Assurances. After Closing and on an on-going basis: (a) Buyer shall execute and deliver or use reasonable efforts to cause to be executed and delivered any other instruments of conveyance and take any other actions as Seller reasonably requests 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 (including reassignment from Buyer to Seller of any Properties that were conveyed in violation of valid preferential purchase rights or material consents to assignment disclosed in Schedules to this Agreement and subject commensurate payment adjustment), or to implement Buyer’s assumption of obligations pursuant to Article 12.2; and (b) Seller shall execute and deliver or use reasonable efforts to cause to be executed and delivered any other instruments of conveyance and take any other actions as Buyer reasonably requests to more effectively put Buyer in possession of the Properties conveyed or to have been conveyed in accordance with the terms of this Agreement. 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 owned by Seller, which were reflected in the financial information provided to Buyer in the Data Room or were, as of the

19.8 Successors and Assigns. Except as expressly provided otherwise in this Agreement, this Agreement may not be assigned, (in whole or in part), without the express prior written consent of the non-assigning Party, except that Seller may assign its rights to proceeds hereunder.

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.

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. Each Party has had an adequate opportunity to review each and every provision of this Agreement and to submit the same to legal counsel for review and advice.

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.
