(b) For purposes of allocating liability between Sellers and Buyer under the indemnity provisions of this Agreement, Losses shall be deemed to be attributable to ownership, use, operation, maintenance, improvement or abandonment as of the time that an injury or alleged injury is suffered by a Person, and not as of the time that a claim or legal action is filed or as of the time that an allegedly deficient condition was created. Page 15 of 53 3.4 CLAIMS PROCEDURES. (a) Any party entitled to indemnification hereunder (the "Indemnitee") shall notify the party liable for such indemnification (the "Indemnitor") in writing of any Loss which the Indemnitee has determined has given or could give rise to a claim for indemnification under this Agreement. Such notice (a "Notice of Claim") shall specify in reasonable detail, so far as the Indemnitee is able to do so, the nature and any particulars of any such claim giving rise to a right of indemnification (including the amount thereof, so far as the Indemnitee is able to do so). Any Notice of Claim shall be given promptly after Indemnitee has actual knowledge of the Loss, and in no event more than 45 calendar days after such knowledge (or, in the case of a Loss involving filing of a complaint or other pleading, such Notice of Claim shall be given to allow reasonable time for the Indemnitor to answer or otherwise respond to such pleading). Failure or delay of the Indemnitee to give such notice shall relieve the Indemnitor of any liability to the extent actual prejudice results. The Indemnitee shall permit access (or ensure that any relevant Affiliate permits access) by the Indemnitor or its representatives to all personnel, records and other materials reasonably required by them for their use in connection with any Claim, and shall cooperate with the Indemnitor in connection with all such Claims as reasonably required by the Indemnitor. (b) With respect to any suit, cause of action, legal or administrative proceeding, arbitration, demand or claim by a third party (a "Claim") that could give rise to indemnification under this Agreement, the Indemnitor shall defend (in the name of the Indemnitee, if necessary), at its own expense with attorneys of its own selection (and who shall be reasonably satisfactory to the Indemnitee), any such Claim, and the Indemnitee shall not settle any such Claim without the Indemnitor's written consent; provided, that if any Indemnitor is not defending such Claim within 30 calendar days after having been afforded the opportunity to do so in accordance with this Section, then the Indemnitee shall have the right to reasonably defend the Claim in such manner as it may deem appropriate at the cost and expense of the Indemnitor, and the Indemnitor shall promptly reimburse the Indemnitee therefor in accordance with this Agreement, and the Indemnitor's consent to any proposed settlement shall not be unreasonably withheld. Notwithstanding the assumption by the Indemnitor of the defense of any Claim as provided in this Section 3.4, the Indemnitee shall be permitted to participate in the defense of such Claim and to employ counsel at its own expense (subject to the right of the Indemnitor to control and direct such defense). (c) If the Indemnitor does not assume the defense of any Claim, then any failure of the Indemnitee to defend shall not relieve the Indemnitor of its obligations hereunder; provided that the Indemnitee shall have given the Indemnitor notice of its intention not to defend and afforded the Indemnitor the opportunity to assume the defense within such period as may be reasonable (taking into consideration when determining whether such period is reasonable, the time when notice was given to the Indemnitee by the Indemnitor that such Indemnitor did not intend to assume the defense thereof). Notwithstanding any other provision of this Section 3.4, no Indemnitor shall settle any Claim without the consent of the Indemnitee if such settlement would involve an admission by the Indemnitee of criminal liability, the consent to any equitable order or injunction or otherwise materially and adversely affect the Indemnitee or its subsidiaries. Page 16 of 53 3.5 SECURITY FOR SELLERS' LIABILITIES. On the Closing, Sellers shall deliver to Buyer a Guaranty Agreement executed by Chevron Corporation in the form attached as Exhibit J to this Agreement, by which Chevron Corporation shall guarantee to Buyer the performance and payment when due by each of Sellers of certain obligations arising under this Agreement. 3.6 SECURITY FOR BUYER'S LIABILITIES. (a) On the Closing, Buyer shall deliver to the MMS a supplemental performance bond in the penal sum required by the MMS executed and acknowledged by Buyer and sureties acceptable to CUSA and the MMS in the form of supplemental bond prescribed by the MMS attached as Exhibit K to this Agreement (the "MMS Performance Bond"), guaranteeing performance and payment when due by Buyer of its Abandonment Obligations with respect to the interests in the offshore MMS oil and gas leases transferred hereunder. A duplicate original of the MMS Performance Bond shall be provided to Sellers on the Closing. Buyer shall not enter into any amendment, waiver, assignment or termination of the MMS Performance Bond without the prior written consent of CUSA. CUSA's consent shall not be unreasonably withheld for amendments of such bond that do not materially impact CUSA's security, or for substitution of a surety that has on the substitution date credit ratings from Standard & Poor's or the equivalent that are as good as or better than the credit ratings for the surety or sureties accepted by CUSA on the Closing. CUSA may otherwise withhold its consent to amendments, waivers, assignments or terminations of the bond in its sole discretion, except as described in clauses (e) and (f) below. Sellers and Buyer shall endeavor to cause the MMS to agree that in the event of any default with respect to Buyer's Abandonment Obligations, the MMS would proceed against the MMS Performance Bond before proceeding against CUSA. CUSA and the sureties providing the MMS Performance Bond shall enter into a similar agreement. (b) On the Closing, Buyer shall deliver to Sellers a performance bond in favor of Sellers in a penal sum equal to Five Million Dollars ($5,000,000) minus the penal sum required for the MMS Performance Bond in clause (a) above, executed and acknowledged by Buyer and sureties acceptable to Sellers in the form attached as Exhibit L to this Agreement ("Sellers' Performance Bond"), guaranteeing to Sellers the performance and payment when due by Buyer of the Buyer's Abandonment Obligations arising under this Agreement. Seller's Performance Bond shall be maintained by Buyer in full force and effect at all times until the earlier of (i) the date on which all Abandonment Obligations assumed by Buyer have been completely performed and satisfied or (ii) the date Buyer's Abandonment Obligation expenditures are fully credited against the penal sum of such bond, as described in clauses (c) and (d) below. Sellers' consent shall not be unreasonably withheld for substitution of a surety that has on the substitution date credit ratings from Standard & Poor's or the equivalent that are as good as or better than the credit ratings for the surety or sureties accepted by Sellers on the Closing. (c) Buyer shall maintain accurate records of their actual expenditures incurred in performing its Abandonment Obligations, and shall deliver to Sellers reports of such expenditures promptly after each calendar year in which Abandonment Obligations are performed. For purposes of this Agreement, any expenditures for an Abandonment Obligation completion of which requires approval from a Governmental Authority or contract Page 17 of 53 party shall not be deemed expended until the calendar year in which such approval is obtained. Sellers or their authorized representatives may audit Buyer's records for the purpose of verifying the actual expenditures incurred in performing Buyer's Abandonment Obligations. Any disputes concerning the amount of such expenditures or their attribution to performance of Abandonment Obligations shall be resolved in accordance with Section 12.6 below. (d) Sellers and Buyer shall jointly maintain an account of Buyer's Abandonment Obligation expenditures determined in accordance with clause (c) above. In such account, Buyer's expenditures for those Abandonment Obligations covered by the MMS Performance Bond shall be credited against the penal sum of the MMS Performance Bond. Buyer's other Abandonment Obligation expenditures shall be credited against the penal sum of Sellers' Performance Bond until an amount equal to such penal sum is attained. At any time after any calendar year in which Abandonment Obligation expenditures are credited against the penal sum under the MMS Supplemental Performance Bond under this clause (d), Buyer may require that CUSA consent to partial reduction of such penal sum in the amount of such credit, conditioned on the consent of MMS to such partial reduction. At any time after any calendar year in which Abandonment Obligation expenditures are credited against the penal sum under the Sellers' Performance Bond under this clause (d), Buyer may require that Sellers consent to partial reduction of such penal sum in the amount of such credit. (e) Until a consent to reconveyance or surety bond termination is executed by Sellers, the performance bonds described in this Section 3.6 shall remain in full force and effect and Sellers shall have all remedies available under such instruments or applicable Laws to enforce performance of Buyer's obligations and to execute on such security in the event of any default in performance or payment of such obligations when due. Buyer waives the right to require Sellers to proceed against or exhaust any particular security or make any election of remedies. (f) Buyer shall not sell, assign, pledge, grant a security interest in or otherwise transfer ("transfer") any interest in the real property interests included in the Transferred Properties, and Plains Resources Inc. shall not transfer any interest in any subsidiary designated to hold title to the Transferred Properties or the interests transferred hereunder in GGP, PANGL, PAPCO or PATC, without first obtaining the written consent of Sellers. Sellers shall not withhold their consent to such transfer if the transfer will meet each of the following criteria to Sellers' reasonable satisfaction: (i) The transfer will not increase the cost or time for performance of Sellers' then remaining retained Abandonment Obligations. (ii) The transfer will not impair the ability or likelihood of performance of Buyer's then remaining assumed Abandonment Obligations. (iii) Sellers will continue to hold unimpaired all rights granted by Buyer in accordance with this Agreement applicable to performance of Sellers' then remaining retained Abandonment Obligations, including rights to use of emission reduction credits, rights to Clean Seas spill response commitments, Page 18 of 53 rights as an additional insured under Buyer's insurance, and rights under the MMS Performance Bond and Sellers' Performance Bond required hereunder. Notwithstanding the foregoing, Sellers hereby consent to Buyer's granting of security interests in the Transferred Properties to the lenders providing acquisition funding for the Closing of this Agreement and to the sureties providing the MMS Performance Bond and the Sellers' Performance Bond, and their respective successors or assigns or substitute parties (provided that Sellers' consent based on the above criteria shall be required for any execution, foreclosure, trustee sale or other transfer by or on behalf of such lenders or sureties, which would result in a party other than the lender or sureties acquiring an interest). If Sellers' consent based on the above criteria is obtained with respect to a transfer in which the transferee provides Sellers with bonds in forms and from sureties satisfying the requirements for the MMS Performance Bond and Sellers' Performance Bond hereunder, Sellers shall consent to the release of the respective bond or bonds furnished by Buyer. ARTICLE 4 DEPOSIT AND PURCHASE PRICE 4.1 DEPOSIT. Within three Business Days after the Execution Date, Buyer shall deliver to Sellers a deposit of One Hundred Thousand Dollars ($100,000) (the "Deposit").

Buyer shall have the right to have their representatives audit the records used by Sellers in calculating such measurement and valuation. (b) PAYABLES. All credits and payment obligations associated with the Transferred Properties (including accounts payable and prepayments) which have been paid by Sellers and their Affiliates or which have accrued on or before the Closing Date and which relate to liabilities that have been assumed by Buyer or for which Buyer is otherwise responsible shall be prorated to CUSA or CPL, as applicable, for the period prior to the Closing Date and to Buyer, for the period on and after the Closing Date. Sellers shall pay all such items due prior to the Closing Date and Buyer shall pay for all such items due on and after the Closing Date. (c) RECEIVABLES. Accounts receivable or other rights to revenue associated with the Transferred Properties, to the extent that such accounts receivable and rights to revenue are attributable to transactions prior to the Closing Date, shall not be part of the sale but shall remain the property of Sellers whenever collected. (d) TAXES. The allocation between Sellers and Buyer of responsibility for and payment of all property and excise taxes shall be made in accordance with the provisions of Article 10 below. 4.4 SETTLEMENT STATEMENT. A preliminary estimate of the value of the Measured Inventories as of the Closing Date under Section 4.3(a) above shall be calculated by Sellers and set forth in a settlement estimate (the "Settlement Estimate") delivered to Buyer not later than five (5) Business Days prior to the scheduled date for Closing. A final determination of the value of the Measured Inventories as of the Closing Date under Section 4.3(a) above shall be calculated by Sellers and set forth in a settlement statement (the "Settlement Statement") delivered to Buyer not later than 180 calendar days after the Closing. The Settlement Statement shall contain information detailing the basis for Sellers' calculations, and Buyer and its representatives shall have access to such records of Sellers as may be reasonably requested Page 20 of 53 for verifying the measurements and calculations. If Buyer gives to Sellers written notice of dispute of any element of the Settlement Statement within 60 calendar days after receiving the Settlement Statement, (i) Sellers or Buyer, as the case may be, shall pay all undisputed amounts to the other within 75 calendar days after receiving the Settlement Statement and (ii) the disputed amount shall be negotiated between Sellers and Buyer. If such negotiations do not result in a resolution of the dispute within fifteen calendar days after Buyer's notice of dispute, the disputed amount shall be determined by one partner of an independent accounting firm jointly selected by Sellers and Buyer, whose determination shall be consistent with the provisions of this Agreement and shall be final and conclusive. The disputed amount shall be payable by the parties owing such amount within five Business Days following settlement or resolution of the dispute. Any amounts owing under the Settlement Statement shall bear interest at the Interest Rate from the Closing Date until paid. 4.5 ALLOCATION OF PURCHASE PRICE. The Purchase Price shall be allocated among the Transferred Properties potentially subject to rights of first refusal in accordance with Schedule 10 attached to this Agreement. ARTICLE 5 CLOSING 5.1 TIME AND PLACE OF CLOSING.

IN ADDITION, BUYER ACKNOWLEDGES THAT SELLERS HAVE NOT MADE, AND SELLERS HEREBY EXPRESSLY DISCLAIM AND NEGATE, ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, FITNESS FOR PARTICULAR PURPOSE, OR CONFORMITY TO MODELS OR SAMPLES OR MATERIALS AND ANY OTHER REPRESENTATION OR WARRANTY, EXPRESS, STATUTORY OR IMPLIED RELATING TO THE TRANSFERRED PROPERTIES. EXCEPT AS EXPRESSLY SET FORTH IN ARTICLE 7, AND WITHOUT LIMITATION ON THE DISCLAIMERS SET FORTH IN ARTICLE 7, BUYER IS ACQUIRING THE TRANSFERRED PROPERTIES IN AN "AS-IS, WHERE-IS" CONDITION WITH ALL FAULTS. (b) DUE DILIGENCE. Subject to Section 8.2, Buyer shall have the right to conduct its own due diligence review of the Transferred Properties and the Partnerships' Facilities, the title and other public records applicable thereto, and the records made available by Sellers to Buyer pursuant to the Confidentiality Agreement with respect to (i) the quality and validity of Sellers' title to the Transferred Properties and the Partnerships' Facilities, (ii) the Page 35 of 53 environmental condition of the Transferred Properties and the Partnerships' Facilities, (iii) the structural condition of the Transferred Properties and the Partnerships' Facilities, and (iv) confirmation that financial and operational results for 1998 and the portion of 1999 through the Approval Date are consistent with previously disclosed financial and operating information. Such due diligence shall be conducted in substantial compliance with a timetable and plan to be agreed upon in writing by Sellers and Buyer. If Buyer's examination results in a Material Discovery of Title Defects, Environmental Conditions, Structural Conditions or adverse condition revealed by the confirmation described in clause (iv) above (an "Item (iv) Condition") of the Transferred Properties and the Partnerships' Facilities, then Buyer shall have the right to bring the results of its examination and investigation to the attention of Sellers by written notice if and only if such notice is given to Sellers by the earlier of (i) 15 days prior to the scheduled Closing Date in accordance with Section 5.2 above or (ii) June 15, 1999 (the "Approval Date"). For purposes of this Section 8.1, a "Material Discovery" shall mean the discovery of Title Defects, Environmental Conditions, Structural Conditions or Item (iv) Conditions not known to Buyer as of the Execution Date, or not set forth with reasonable specificity in the data room or Disclosure Letter, which could reasonably be expected to reduce the economic value of the Transferred Properties and the Partnerships' Facilities by (or impose a liability on Buyer of) at least Fifty Thousand Dollars ($50,000) per individual Title Defect, Environmental Condition, Structural Condition or Item (iv) Condition and total at least One Hundred Thousand Dollars ($100,000) in the aggregate in order to cure or remediate such matters. (c) RECOURSE FOR DUE DILIGENCE MATTERS. If written notice of such facts constituting a Material Discovery is given to Sellers on or before the Approval Date, the parties agree to discuss appropriate remedial actions or adjustments to this Agreement to take into account the individual Title Defects, Environmental Conditions, Structural Conditions or Item (iv) Conditions constituting such Material Discovery. If (i) Sellers receive such timely notice from Buyer and (ii) Sellers undertake to Buyer's reasonable satisfaction to cure or indemnify Buyer against the individual Title Defects, Environmental Conditions, Structural Conditions or Item (iv) Conditions constituting such Material Discovery, then the closing condition specified in Section 6.2(g) shall be deemed satisfied. If Sellers do not provide such an undertaking and the parties cannot agree on an appropriate amendment to this Agreement within 15 calendar days after such written notice is given, then Buyer shall have the right to terminate this Agreement within 10 calendar days after such written notice by giving written notice of termination to Sellers; otherwise, Buyer shall accept the Transferred Properties and the Partnerships' Facilities in their "as is" condition and the parties shall proceed with the Closing without exclusion of assets or reduction of Purchase Price. (d) SELLERS' ADDITIONAL DISCLOSURES. Sellers may similarly conduct such examination or investigation as it may choose with respect to the Transferred Properties and should it determine that a matter exists which should have been disclosed in any of the schedules or in any other written disclosure made prior to the execution of this Agreement, it shall add such matter (any matter so added being called a "Sellers Defect") to the appropriate schedule or disclosure by giving written notice of such addition to Buyer promptly after Sellers' discovery thereof but in no event less than 15 calendar days prior to the Closing Date, and for the purposes of Sellers' representations and warranties, each such Sellers Defect shall be deemed to have been disclosed on such schedule or disclosure on the Execution Date. If Page 36 of 53 any such Sellers Defect is a Title Defect, Environmental Condition, Structural Condition or Item (iv) Condition that would result in or be part of a Material Discovery, Buyer shall have the right to include the Sellers Defect in a notice of Material Discovery given to Sellers within 10 calendar days after Buyer is notified of the Sellers Defect. 8.2 BUYER'S RIGHT TO ENTER. (a) As contemplated to facilitate Buyer's due diligence review under Section 8.1 above, Sellers hereby grant to Buyer and its representatives the right at Buyer's sole risk to enter onto the Transferred Properties from time to time upon reasonable notice to Sellers, for the purposes of inspection of the Transferred Properties, including both internal and external inspection, evaluation and appraisal of such facilities. If Buyer plans to perform any excavation, take soil samples, or conduct other activities on the Transferred Properties which may affect Sellers' operations, Buyer shall provide Sellers with written notification of such plans and shall obtain Sellers' written approval and all necessary approvals from Government Authorities prior to conducting any such activities. Buyer shall restore the Transferred Properties to their condition existing prior to Buyer's operations or activities upon the Transferred Properties pursuant hereto, including repairs or maintenance as such are required as a result of Buyer's operations or activities. When and as reasonably requested by Buyer, Sellers shall endeavor to secure comparable rights for Buyer to enter onto and to conduct due diligence activities with respect to the Partnerships' Facilities, on terms and conditions protecting the partnerships and their partners (including Sellers) comparable to those set forth in this Article 8. (b) Buyer shall obtain and maintain at a minimum the following types and amounts of insurance with respect to the exercise by Buyer and its representatives of the rights granted in this Section 8.2: (i) comprehensive public liability and property damage insurance with limits of not less than $2,000,000 combined single limit per occurrence; (ii) automobile, aircraft and watercraft liability insurance with a $2,000,000 limit; (iii) workers' compensation insurance with limits as required by law; and (iv) employer's liability insurance with a $2,000,000 limit. Prior to any exercise of the rights granted hereby, Buyer shall furnish to Sellers a certificate evidencing the existence of the insurance required hereunder, confirming that the insurance: (v) is obtained from and maintained with an insurer acceptable to Sellers; (vi) covers Buyer's obligations under the indemnity provisions of this Agreement; Page 37 of 53 (vii) names Chevron Corporation and its Affiliates as additional insureds (or, in the case of workers' compensation insurance, provides a waiver of subrogation to any rights against Chevron Corporation and its Affiliates); and (viii) contains a provision pursuant to which the insurer agrees not to cancel or modify the insurance coverage without furnishing at least thirty (30) days' prior written notice to Sellers. (c) Buyer waives and releases all claims against Chevron Corporation and its Affiliates, and their directors, officers, employees and agents, for injury to or death of any persons or damage to property arising in any way from the exercise of rights granted to Buyer by this Section 8.2 or the activities performed pursuant to this Section 8.2 by Buyer or its representatives on the Transferred Properties and the Partnerships' Facilities. (d) Buyer shall release, defend, indemnify and hold harmless Chevron Corporation and its Affiliates, and their directors, officers, employees and agents, from and against any and all Losses arising out of (i) any and all statutory or common law liens or other encumbrances for labor or materials furnished in connection with such rights granted hereunder, including but not limited to samplings, studies or surveys that Buyer may conduct with respect to the Transferred Properties pursuant to this Section, or (ii) any injury to or death of persons or damage to property occurring in, on or about the Transferred Properties as a result of such exercise of the rights granted hereunder or activities conducted pursuant to this Section 8.2. Such indemnity shall apply whether or not an indemnitee was or is claimed to be passively, concurrently, or actively negligent, and regardless of whether liability without fault is imposed or sought to be imposed on one or more of the indemnitees. This indemnity shall not apply to the extent that it is void or otherwise unenforceable under applicable law in effect on or validly retroactive to the execution date of this Agreement and shall not apply where such loss, cost, damage, injury, liability or claim is the result of the sole negligence or willful misconduct of any indemnitee. (e) Buyer agrees not to permit its activities permitted by this Section to unreasonably interfere with the business and operations of the Transferred Properties, and agrees that such inspections and all such documents shall be subject to the Confidentiality Agreement. Such activities shall also be conducted in compliance with Laws and Sellers' reasonable safety regulations. 8.3 OPERATION OF TRANSFERRED PROPERTIES PRIOR TO CLOSING. (a) Sellers shall promptly notify Buyer of any casualty to the Transferred Properties or the Partnerships' Facilities, or any eminent domain or other condemnation proceeding commenced with respect to such properties, between the Execution Date and the Closing. If any such Losses relate to or may result in the loss of any material portion of the Transferred Properties or the Partnerships' Facilities ("material" for purposes of this Section 8.3 shall mean a net loss incurred by or allocated to Sellers' interest in excess of $500,000), either Sellers or Buyer may, at their option, elect to terminate this Agreement by written notice to the other parties given within 15 calendar days after becoming aware of such Page 38 of 53 casualty or condemnation proceeding, in which event Sellers shall refund the Deposit as provided in Article 4, and none of the parties shall have any further rights or obligations hereunder. If no such notice of termination is timely given, the Agreement shall continue in effect, and upon the Closing, Buyer shall be entitled to any property insurance proceeds, compensation, awards, or other payments or relief resulting from such casualty or condemnation proceeding (other than proceeds or other relief expended by Sellers in remedying the casualty). (b) Except as otherwise provided herein, Sellers will not, without the prior written approval of Buyer, sell, transfer or abandon any portion of the Transferred Properties belonging to them other than the sale, transfer or abandonment in the ordinary course of the operations consistent with past practices of (i) Hydrocarbon Inventories of any value or (ii) other items having a per item fair market value of less than Twenty-Five Thousand Dollars ($25,000) of materials, supplies, spare parts, inventories, furniture, motor vehicles, rolling stock, tools, implements, appliances, machinery, equipment, improvements or other tangible personal property or fixtures forming a part of the Transferred Properties. (c) Sellers shall use commercially reasonable efforts to cause the PAPCO, PANGL, PATC and GGP partnerships to distribute to their partners, including Sellers, prior to Closing, any cash that is not necessary for the ordinary course of business funding requirements of the applicable entity. Such cash shall be allocated between Sellers and Buyer in accordance with Section 2.4 above. 8.4 ANNOUNCEMENTS. Except for disclosures that Sellers or Buyer reasonably believe are required by Law or any securities exchange to which Sellers or Buyer may be subject, neither Sellers nor Buyer shall issue any press release or otherwise make any public announcement on or prior to the Closing Date with respect to this transaction without the prior written consent of the other parties, which shall not be unreasonably withheld or delayed. 8.5 REQUIREMENTS FOR TRANSFER OF TRANSFERRED PROPERTIES. (a) RIGHTS OF FIRST REFUSAL. Certain of the Transferred Properties, identified in Schedules 10 and 11 attached to this Agreement, are potentially subject to rights of first refusal. Sellers and Buyer have in good faith allocated the Purchase Price among the Transferred Properties potentially subject to such rights of first refusal in Schedule 10 attached to this Agreement. Sellers and Buyer shall cooperate and shall promptly undertake such action as may be required to satisfy obligations under any rights of first refusal with respect to the Transferred Properties; provided that neither Sellers nor Buyer shall be required to pay any additional consideration beyond that contemplated (if any is contemplated) by the terms of such rights. If a third party shall properly exercise any such right, the Transferred Properties shall be excluded from the sale to Buyer hereunder and the Purchase Price reduced by the consideration received by Sellers from the third party in exercise of such right; provided, however, that should the Purchase Price be reduced more than ten percent (10%) due to the exercise of such rights of first refusal, Buyer may terminate this Agreement and receive a full reimbursement of its Deposit. Page 39 of 53 (b) TRANSFER OF APPLICABLE CONTRACTS. At and effective as of the Closing, Sellers shall assign all their rights and delegate performance of all their duties to Buyer under the contracts included in the Applicable Contracts as described in Schedule 5, and Buyer shall assume and agree to perform all duties of Sellers under each such contract. Without limitation, this assumption by Buyer includes their assumption of any termination charges associated with a termination of any such contract made after the Closing. Notwithstanding the foregoing, if any contract provides that any notice to or consent by any third party is required as a condition of assignment, such contract shall not be assigned until and unless such requirements shall have been satisfied. Buyer and Sellers shall use their commercially reasonable efforts, each as to matters within its control, to satisfy such requirements as of the Closing Date. If any such requirement is not satisfied as of the Closing and the Closing occurs, Sellers and Buyer shall consider whether to exclude the affected contracts from the transfer hereunder or to enter into alternative arrangements with each other or with third parties, but in no event shall the Purchase Price be adjusted in respect of exclusion of any contract. (c) TRANSFER OF APPLICABLE PERMITS. Buyer and Sellers shall use their commercially reasonable efforts, each as to matters within its control, to obtain all regulatory approvals, including the Applicable Permits as described in Schedule 6, to be transferred or reissued in favor of Buyer as soon as practicable following the Closing Date and, if possible, during the four-month transition period under the Services Agreement. If the transfer or reissuance of regulatory approvals in favor of Plains has not been obtained or is not reasonably likely to be obtained within such time period, Chevron and Plains shall make alternative arrangements for operatorship that shall be sufficient to ensure that ongoing operational services and responsibilities are transferred to the fullest extent permitted by law. Such alternative arrangements may include, but are not limited to, (i) transfer of the applicable regulatory approvals to a party mutually acceptable to Chevron, Plains, the applicable unit or partnership and regulatory agencies, or (ii) Chevron's and Plains's entering into an agency or contractor relationship in which Chevron remains the named operator or permittee of record. Notwithstanding the continuation of Chevron as a named operator or permittee of record, for purposes of the applicable Unit and Partnership Agreements, Plains shall be recognized as the duly designated operator and manager of the unit and partnership facilities. (d) TRANSFER OF CONTRACTS AND PERMITS TO PARTNERSHIPS AND SUCCESSOR OPERATORS. Certain additional contracts and permits identified in Schedule 7 attached to this Agreement have been issued in the name of CUSA or CPL but are associated with assets or operations now owned or conducted by PANGL, PAPCO, PATC or GGP. Such contracts and permits are not to be transferred to Buyer, but Sellers and Buyer shall use their commercially reasonable efforts, each as to matters within its control, to cause such contracts and permits to be transferred or reissued in favor of the applicable partnership or successor operator. Notwithstanding the foregoing, if any contract or permit provides that any notice to or consent by any Government Authority is required as a condition of assignment, such contract or permit shall not be assigned until and unless such requirements shall have been satisfied. Sellers and Buyer shall use their commercially reasonable efforts, each as to matters within its control, to satisfy such requirements as soon as reasonably practicable following the Closing, during the transition period in which Sellers continue as permittee or operator of record under the Services Agreement. Page 40 of 53 (e) COSTS OF TRANSFER OF APPLICABLE PERMITS. Buyer shall bear all costs and expenses incurred in connection with the transfer, amendment, reissuance or issuance of Applicable Permits to Buyer. Buyer, at its sole expense, shall provide bonds or other security as may be required by Government Authorities for the transfer or reissuance of the Applicable Permits to Buyer. These bonds or other security shall be independent of the security furnished by Buyer to Sellers under Section 3.6. Sellers shall bear all costs and expenses incurred in the transfer, amendment, reissuance or issuance of the contracts and permits identified in Schedule 7 to the applicable partnerships. (f) ADMISSION TO PARTNER OR MEMBER STATUS. It is understood that the transfer of the Partnership Interests or the interests in Clean Seas does not automatically result in Buyer's being admitted to partner status under the terms of the applicable partnership or limited liability company agreements. Sellers and Buyer shall use their commercially reasonable efforts, each as to matters within its control, to cause Buyer to be admitted to partner status under each such partnership or limited liability company agreement effective as of the Closing Date. (g) UNIT OPERATORSHIP. CUSA is the current operator of the Point Arguello Unit pursuant to the applicable unit operating agreements identified in Part B of Schedule 2. Sellers and Buyer shall use their commercially reasonable efforts, each as to matters within its control, to cause Buyer to be designated as the successor operator for such unit effective as of the Closing Date. (h) MANAGING PARTNER AND OPERATOR SUCCESSION. CPL is the current managing general partner of PATC, and the managing general partner and operator of PAPCO and PANGL, and CUSA is the current managing general partner and operator of GGP pursuant to the applicable partnership agreements and management services agreements between each partnership and CPL or CUSA. Sellers and Buyer shall use their commercially reasonable efforts, each as to matters within its control, to cause Buyer to be designated as the successor managing general partner and operator for each such partnership effective as of the Closing Date. 8.6 OTHER GOVERNMENT AUTHORITY REVIEWS AND APPROVALS. (a) PRE-MERGER NOTIFICATION. The consummation of the transactions contemplated by this Agreement may be subject to the premerger notification requirements of Section 7A of the Clayton Act (15 U.S.C. Section 18a) as enacted by the Hart-Scott-Rodino Antitrust Improvements Act of 1976. Sellers and Buyer shall cooperate and promptly undertake all filings and other actions as may be required to comply with such requirements. Should the reviewing agency advise any party of its need for additional information, that party, with the cooperation of the other parties if appropriate, shall promptly respond to the reviewing agency's request. Should the reviewing agency or another interested governmental agency advise any party of its opposition to the transactions contemplated herein, the parties shall diligently endeavor to persuade the agency concerned to abandon its opposition and, failing to do so, the parties shall take such additional action as they may agree. Page 41 of 53 (b) TARIFFS FILED WITH FERC. Certain of the Transferred Properties being conveyed hereunder are operated as a common carrier pipeline system subject to tariffs filed with the Federal Energy Regulatory Commission ("FERC") identified in Schedule 13. Buyer shall adopt such FERC tariffs as of the Closing or, upon notification by Buyer, Sellers shall withdraw such tariffs as Buyer may designate. (c) CHANGE OF OPERATOR. To the extent that Buyer is designated and approved as operator of any of the Transferred Properties, Buyer shall promptly and diligently make all necessary filings and satisfy all necessary requirements with the MMS and any other appropriate Government Authorities in order to transfer operations of such Transferred Properties from Sellers to Buyer. ARTICLE 9 POST-CLOSING COVENANTS 9.1 TERMINATION OF RIGHTS TO SELLERS' INSURANCE. (a) Sellers and Buyer acknowledge that Chevron Corporation has maintained worldwide programs of property and liability insurance coverage for itself and its Affiliates, including with respect to the Partnership Interests owned by its Affiliates and the other Transferred Properties. Such programs have been designed to achieve a cost-effective, coordinated risk-management package for the entire corporate group. All of the insurance policies through which such worldwide programs of coverage are presently or have previously been provided are herein called the "Chevron Corporation Policies." (b) It is the understanding and intention of Sellers and Buyer that: (i) from and after the Closing, no insurance coverage shall be provided for Buyer under the Chevron Corporation Policies relating to the Transferred Properties; and (ii) from and after the Closing, no claims regarding any matter whatsoever, whether or not arising from events occurring prior to the Closing, shall be made against or with respect to the Chevron Corporation Policies by Buyer. (c) Buyer, on behalf of itself and its successors and assigns, hereby releases, to the extent permitted by applicable Law, Sellers and their Affiliates from any claim made after the Closing against or with respect to any of the Chevron Corporation Policies by or through Buyer (except for Buyer's entitlement to proceeds of insurance with respect to casualties as provided in Section 8.3(a)). (d) Nothing contained in the foregoing provision of this Section 9.1 shall in any Page 42 of 53 way limit, impair or constitute a release or discharge of any right of Buyer or obligation of Sellers with respect to any representation, warranty, covenant, agreement, indemnity or other obligation of Sellers contained in this Agreement (regardless of whether the same was, is or may be covered by any insurance described herein), all of which rights and obligations shall continue in full force and effect. 9.2 BUYER'S INSURANCE. Prior to the Closing Date, Buyer shall purchase and shall thereafter maintain in full force and effect Commercial General Liability Insurance (Claims Made Basis) including, but not limited to, pollution liability coverage for sudden and accidental leaks or spills covering Buyer's ownership and operation of the Transferred Properties (including Sellers' obligations under any Applicable Permit pertaining to the Transferred Properties and any liability of Seller as a result of being named on or the holder of such Applicable Permit) of $250,000,000 per accident or occurrence with a policy aggregate totaling $250,000,000 onshore and offshore, with a deductible not in excess of $1,000,000, from insurance carriers having a claims payment rating of A or better from Standard & Poor's, and having an endorsement naming Sellers as the additional insureds with severability of interest clause (cross liability) and waiving subrogation against Sellers, which shall be primary as to any other existing, valid and collectible insurance, self-insurance or fronting policy of insurance of Buyer and/or Sellers or their Affiliates. Such insurance shall specifically provide that covered liabilities include those indemnities and other obligations assumed by Buyer pursuant to Article 3 above. Such insurance shall specifically provide that the insurer agrees not to cancel or materially reduce the insurance coverage without furnishing at least thirty (30) days' prior written notice to Sellers. Such insurance is to remain in effect until all necessary federal, state or local agencies and contract parties have approved the completion of all Abandonment Obligations assumed by Buyer hereunder. Such insurance in no way limits Buyer's obligation with respect to any claim, damage or loss resulting from Buyer's ownership and operation of the Transferred Properties, oil spills, abandonment of wells, facilities and remediation of the surface, subsurface and waters as required herein or Buyer's obligations and agreements (including indemnity obligations) under any provision of this Agreement. 9.3 REMOVAL OF PROPRIETARY TECHNICAL INFORMATION. Except as provided in any third party license included in the Transferred Properties, Sellers may remove all proprietary technical information in written form that is owned by a third party (or is not in use or has not been in use within one (1) year prior to Closing) at the Transferred Properties or that is proprietary to Sellers or their Affiliates. Schedule 14 identifies the items containing such proprietary technical information as of the Execution Date. Page 43 of 53 9.4 REPLACEMENT OF SELLERS' IDENTIFICATION. Buyer shall, at its own expense and in a timely manner not exceeding three months after the Closing, remove or cause to be removed all signs and placards which identify Sellers as prior owner or operator of each of the Transferred Properties, including any usage of trademarks or trade names of Sellers and their Affiliates. Buyer shall, at its own expense and in a timely manner not to exceed one week after the Closing, erect or install signs and placards as may be required by state or other governmental agencies identifying Buyer as the owner and/or operator of each of the Transferred Properties. 9.5 ACCESS BY SELLERS AFTER CLOSING. In the event of Closing, Buyer shall grant to Sellers a right of entry to the Transferred Properties to perform retained Abandonment Obligations at Sellers' sole cost, risk and expense, if Sellers, in their sole discretion, determine that such action is necessary to reduce alleged future liabilities of Sellers. Sellers agree to indemnify, hold harmless, and defend Buyer from and against all loss, liability, claims, fines, expenses, costs (including attorneys' fees and expenses), and causes of action caused by or arising out of Sellers' use of the right of entry granted hereby and/or Sellers' performance of retained Abandonment Obligations hereunder. Any such entry or action on the Transferred Properties by Sellers shall not be construed as an admission of responsibility by Sellers, nor shall Sellers' action lessen or reduce Buyer's responsibility for liability. A perpetual right of entry for retained Abandonment Obligations shall be incorporated in the final documents transferring title to Buyer. Promptly after all Abandonment Obligations allocated to Sellers have been completed, Sellers shall execute, acknowledge and deliver such documents as Buyer may reasonably request to terminate such rights of entry. 9.6 ABANDONMENT PROJECT PERMITTING, PLANNING AND EXECUTION SERVICES. Effective on the Closing Date, Sellers and Buyer shall each perform certain project permitting, planning and execution services as described in Schedule 13 attached to this Agreement. 9.7 SERVICES AGREEMENT. Effective on the Closing Date, Sellers and Buyer shall enter into a Services Agreement for (a) the provision of administrative and operational services by Sellers and their Affiliates to Buyer during a transition period not exceeding four months commencing on the Closing Date (provided that Sellers' Y2K supervisory services shall be provided for the full duration of the Y2K work program described in Section 7.6(b) above), and (b) the provision of project management services by Sellers to Buyer with respect to the Reconfiguration 2 Project defined in the letter dated April 29, 1999 from Sellers to the PAPCO and PATC partners attaching a proposed Application for Expenditure, effective when an Application for Expenditure relating to such project is approved by the PAPCO and PATC partnerships. The Services Agreement shall be substantially in the form of Exhibit E attached hereto. Sellers and Buyer shall negotiate mutually satisfactory definitions of the transition services and Reconfiguration 2 Project services, and the compensation applicable to such services, promptly following the Execution Date and in any event prior to the Closing Date. In connection with CUSA's performance of transition services, CUSA will not terminate its retained Point Arguello Unit Contract Personnel Agreement (the "Texaco Personnel Agreement") dated as of October 1, 1996 with Texaco Exploration and Production, Inc. ("Texaco") until CUSA's operatorship of Platform Harvest is transferred to Buyer or until the end of the transition period under the Services Agreement, whichever occurs earlier. Page 44 of 53 ARTICLE 10 TAXES 10.1 TRANSFER TAXES.

(a) All real estate, occupation, ad valorem, personal property taxes and charges (e.g., direct assessments) on any of the Transferred Properties shall be prorated as of the Closing Date.

At the Closing Date, Buyer shall pay Sellers all state and local sales or use taxes determined by Buyer's independent accounting firm, PricewaterhouseCoopers LLP, to be applicable, and Sellers shall remit such amount to the appropriate taxing authority in accordance with applicable law, provided, however, that if Buyer hold a direct payment permit which is valid on the Closing Date, Buyer shall assume all responsibility for remitting to the appropriate taxing authority the state and local sales and use taxes due and shall provide Sellers with any exemption certificates or other documentation required under applicable Law in lieu of paying Sellers the taxes due. Buyer shall hold harmless and shall indemnify Sellers for any sales or use taxes assessed against Sellers by any taxing authority in respect of this sale including the amounts of any penalties, interest and attorney's fees. (c) In the event that the transferor or transferee of any of the Transferred Properties receives a notice of liability for additional taxes or charges (the party receiving such notice of liability will hereafter be referred to as the liable party) which are assessed upon or levied against any of the Transferred Properties after the Closing Date with respect to any period for which the liable party is not responsible for payment under the above terms then the other party (being the transferee or transferor, respectively) (hereafter referred to as the responsible party) after receiving such notice of liability shall have the option of either: Page 45 of 53 (i) Paying the tax directly, including payment under protest to preserve the right to contest the liability, or (ii) Challenging the liability asserted in such notice, taking all action necessary and incident to such challenge. If the responsible party elects to challenge the validity of such bill or any portion thereof, the liable party shall extend reasonable cooperation to the responsible party in such efforts at no expense to the responsible party. Notwithstanding the foregoing, the liable party may elect to pay such notice of liability; however, the responsible party will not have to reimburse such payment unless the responsible party has consented to that payment and reimbursement and the responsible party's right to contest such liability is preserved. (d) Should this purchase and sale constitute an isolated or occasional sale and not be subject to sales or use tax with any of the taxing authorities having jurisdiction over this transaction, no sales tax will be collected by Sellers from Buyer at the Closing Date. Sellers agree to cooperate with Buyer in demonstrating that the requirements for an isolated or occasional sale or any other sales tax exemption have been met. 10.3 PARTNERSHIPS AND PARTNERSHIP INTERESTS. Sellers shall be responsible for the discharge of all notice requirements contained in the partnership agreements related to the transferred partnership interests.

The party receiving a refund shall make a good faith effort to ascertain the source of the refund and to resolve by mutual consent the ownership of any refunds related to the subject properties. 10.5 COMPLIANCE AND CONTESTS. Subject to the reimbursement of reasonable out-of-pocket expenses, the parties hereto will provide each other such records and assistance as may be reasonably requested by any of them in connection with the preparation of any tax return, and audit or other examination by any taxing authority, and any judicial and administrative proceedings related to the liability for taxes (including without limitation, any additions to or refund of taxes).

Notwithstanding the foregoing, Buyer shall have the right, prior to the Approval Date and effective on notice given to Sellers, to designate one or more of its wholly-owned subsidiaries, or Plains All American Pipeline, L.P. or its affiliated partnerships, to receive all or designated portions of the Transferred Properties and interests in GGP, PANGL, PAPCO, PATC and Clean Seas to be transferred at the Closing Date, PROVIDED that at the Closing Buyer shall furnish Sellers with (i) a Guaranty Agreement in substantially the form of Exhibit J attached hereto executed by Plains Resources Inc. in favor of Sellers, guaranteeing full payment and performance when due of any obligations hereunder assumed by such subsidiaries, and (ii) certificates by officers of such designated subsidiaries certifying the accuracy of the matters required to be certified by Buyer under Article 7 above and evidencing each such subsidiary's assumption of the duties of Buyer under this Agreement associated with the Transferred Properties and partnership or limited liability company interests to be transferred to such subsidiary; and PROVIDED FURTHER that Buyer shall be solely responsible for securing any consents required from unit members, partners or Government Authorities for designation of such subsidiaries as owners, partners or operators of the applicable units and partnerships. 12.6 GOVERNING LAW AND DISPUTE RESOLUTION. (a) The interpretation and enforcement of this Agreement, and any arbitration and arbitral decision pursuant to subparagraph (c) below, shall be governed by the substantive law of the State of California, without the application of its conflict of law rules; provided, however, questions concerning arbitrability under the dispute resolution provision hereof shall be governed exclusively by the United States Arbitration Act. Page 48 of 53 (b) Should any party hereto institute any arbitration or court proceeding permitted under this Section 12.6 to enforce any provision hereof or for damages by reason of the breach, default or liability of the other party arising out of any provision of this Agreement or otherwise, the prevailing party (as determined by the arbitral panel or court) shall be entitled to recover costs of the arbitration or court proceeding and reasonable attorneys' fees to be fixed by the arbitral panel or court. (c) The parties desire to avoid all forms of traditional litigation and therefore agree that all disputes, controversies or claims arising out of or relating to this Agreement (collectively "Disputes") shall be resolved in accordance with the following procedures: (i) The parties shall use all commercially reasonable efforts to resolve Disputes through direct discussions. The management of each party commits itself to respond promptly to any communications concerning Disputes. (ii) Within thirty (30) days of written notice that there is a Dispute, representatives of the parties with authority to settle the matter shall meet at a mutually acceptable time and place in San Francisco, California, or such other location as may be agreed, and as often thereafter as they deem reasonably necessary in an effort to reach an amicable resolution. If a negotiator intends to be accompanied at a meeting by an attorney, the other negotiator shall be given at least three (3) Business Days' notice of such intention and may also be accompanied by an attorney. (iii) If no amicable resolution is reached as a result of the procedure in subparagraph (ii) hereof, (A) Within sixty (60) days of the written notice referenced in subparagraph (ii), the parties shall exchange written statements of their positions concerning the Dispute, and thereafter shall participate in a final meeting for the purpose of attempting to settle such Dispute. Each party's written statement of position shall state whether the party desires to present live witnesses (and, if so, who) at the next meeting to resolve the Dispute (described hereinafter); (B) Within three (3) weeks of the exchange of written statements, the parties represented by the respective presidents or vice presidents of Sellers and Buyer and with the assistance of such counsel, experts and others as may be appropriate, shall meet and again attempt to reach an amicable resolution or settlement of the Dispute. (iv) If no amicable resolution or settlement is reached as a result of the procedures in subparagraph (i), (ii) or (iii) herein, the Dispute shall be finally resolved through binding arbitration which shall be conducted expeditiously. The parties and arbitration panel shall endeavor to complete the arbitration process within one hundred twenty (120) days of the conclusion of the procedures set forth in paragraph (iii) hereof. Unless otherwise agreed to by the parties, such arbitration shall be conducted in accordance with the Center for Public Resources ("CPR") Rules of Non-Administered Page 49 of 53 Arbitration of Business Disputes (the "CPR Rules"), with Sellers collectively being considered one "party" and Buyer and any of its subsidiaries collectively being considered one "party" for purposes of the CPR Rules. A panel of three (3) arbitrators shall be selected in accordance with the CPR Rules, provided that if the parties fail to select three arbitrators from one or more panels submitted by CPR, CPR shall not have the power to make appointments but shall continue to submit additional panels until all three arbitrators have been selected. Unless the parties agree otherwise, the place of arbitration shall be San Francisco, California. The arbitrators shall not be empowered to award any form of exemplary or punitive damages. As part of any arbitral award pursuant to this paragraph, the arbitrators shall render a reasoned award. The parties consent to judgment on such award being entered in any court having jurisdiction. (d) All negotiations, discussions and documents pursuant to or in furtherance of this dispute resolution are confidential and shall be treated as compromise and settlement negotiations for purposes of the Federal Rules of Evidence and state rules of evidence. (e) Each party is required to continue to perform its obligations under this Agreement pending final resolution of any Dispute. (f) Any judicial proceedings permitted to be brought with respect to this Agreement shall be brought in any state or federal court of competent jurisdiction in the State of California, and the parties generally and unconditionally accept the exclusive jurisdiction of such courts. The parties waive, to the fullest extent permitted by applicable law, any objection which they may now or hereafter have to the bringing of any such action or proceeding in such jurisdiction.

CUSA _____________ BUYER _____________ CPL _____________ 12.7 ENTIRE AGREEMENT AND MODIFICATIONS. (a) This Agreement constitutes the entire agreement between Sellers and Buyer with respect to the subject matter hereof, superseding all prior statements, representations, discussions, agreements and understandings relating to such subject matter; provided, however, that the Confidentiality Agreement shall remain in effect until and unless the Closing occurs. (b) Except as otherwise specifically provided in this Agreement, all covenants, agreements, representations, guaranties, indemnities, and warranties shall survive the Execution Date of this Agreement, the Closing Date, and the delivery and recordation of deeds, assignments or bills of sale which convey the Transferred Properties to Buyer. (c) No modification to this Agreement shall be binding unless in writing and signed by representatives of all parties hereto. The waiver or failure of any party to enforce any provision of this Agreement shall not be construed or operate as a waiver of any further breach of such provision or of any other provision of this Agreement. 12.8 PARTIES IN INTEREST. Nothing in this Agreement, whether express or implied, is intended to confer any rights or remedies under or by reason of this Agreement on any persons other than the parties to it and their respective successors and assigns, nor is anything in this Agreement intended to relieve or discharge the obligation or liability of any third person to any party to this Agreement, nor shall any provision of this Agreement give any third persons any right of subrogation or action over and against any party to this Agreement. 12.9 SEVERABILITY. In the event any provision of this Agreement is held to be invalid by a court or arbitrator of competent jurisdiction, the invalidity of any such provision shall in no way affect any other provision contained herein; provided, however, that any such invalidity does not materially prejudice either Buyer or Sellers in their respective rights and obligations contained in the valid provisions of this Agreement. 12.10 RECORDS AND ASSISTANCE. (a) For a period of seven years after the Closing Date, Buyer will retain the CUSA Records and the CPL Records defined in Sections 2.1 and 2.2 above (the "Records") and will make such Records available to Sellers for inspection and copying upon reasonable notice at Page 51 of 53 Buyer's headquarters (or at such other location in the United States as Buyer shall designate in writing to Sellers) at reasonable times and during regular office hours. Following the expiration of such seven-year period, Buyer shall provide Sellers with 60 days' prior written notice of Buyer's intent to destroy any Records transferred to Buyer pursuant to this Agreement. If Sellers do not consent to the proposed destruction of Records, Buyer shall either continue to retain the Records and continue to make them available to Sellers as provided in the preceding sentence or require Sellers to remove such records at Sellers' cost and expense. To the extent Buyer receive copies of the Records because such Records relate to both the Transferred Properties and properties excluded from the Transferred Properties, Buyer shall maintain those portions of the Records which do not relate solely to the Transferred Properties strictly confidential and shall not disclose any such Records to any person or agency, unless such disclosure is required by Law. (b) In the event of any dispute with respect to the ownership or operation of the Transferred Properties arising out of events which occurred prior to Closing, Buyer shall cooperate with Sellers, at no cost to Buyer, in the resolution of such dispute, including, without limitation, appearing in any litigation which may result therefrom; provided, however, that Buyer's agreement so to cooperate shall not be deemed an acceptance by Buyer of any liability arising from such dispute, as to which the other provisions of this Agreement shall control. Buyer, acknowledging that Sellers have continuing obligations with respect to outstanding lawsuits and claims associated with the Transferred Properties and that Sellers may be parties to claims and litigation asserted after Closing arising out of ownership or operations prior to Closing, shall make available to Sellers, upon Sellers' request at all reasonable times, but at no cost to Buyer, any and all files and business records in Buyer's custody or control transferred by Sellers to Buyer hereunder and, except in the case of a conflict of interest between the parties, any and all individuals employed by Buyer whose testimony or knowledge in the opinion of Sellers' counsel may be necessary or useful to it respecting the issues involved in such claims or litigation or in anticipation thereof. (c) While Sellers are transferring books and records pertaining to the Transferred Properties to Buyer, Sellers by such act in no way intend to waive their attorney-client and work product privileges as to such documents which may be contained in such books and records and in particular with respect to those files associated with outstanding claims and lawsuits which have been identified in this Agreement. Buyer shall continue to maintain the confidential status of those files or turn them over to Sellers if so requested. 12.11 COUNTERPARTS. This Agreement may be executed in two or more counterparts and by different parties on separate counterparts, all of which shall be considered one and the same agreement, and each of which shall be deemed an original.
