EXHIBIT 99.4 PURCHASE AND SALE AGREEMENT THIS PURCHASE AND SALE AGREEMENT (the "Agreement"), is entered into effective the 2nd day of May 2002, by and between Shell Pipeline Company LP, a Delaware limited partnership (formerly known as Equilon Pipeline Company LLC) and Equilon Enterprises LLC dba Shell Oil Products US, a Delaware limited liability company (individually "Shell Pipeline" or "SOP US" and collectively "Seller") and Plains All American Pipeline, L. P. ("Buyer"), a Delaware limited partnership. Seller and Buyer are hereinafter sometimes referred to individually as a "Party" or collectively as the "Parties." Other definitions used in this Agreement are found in Annex A attached hereto and made a part hereof. For and in consideration of the mutual covenants, obligations and benefits made and contained herein, the Parties agree as follows: Article 1 Purchase and Sale A. Subject to the terms and conditions set forth below, Seller agrees to sell, grant, transfer, assign and convey, and Buyer agrees to purchase, acquire, pay for and accept all of Seller's right, title and interest in and to the following real and personal property interests, other than the Excluded Assets (the "Property"); (1) The crude oil pipeline systems shown on Exhibits "A" and "A-1 through "A-4", attached hereto and made a part hereof (the "Pipelines"); (2) All of the partnership interests in Rancho Pipeline Holdings LP and Basin Pipeline Holdings LP (the "Companies"), including the general partners of each; (3) All real property interests described and shown on Exhibits "B-1" through "B-4" attached hereto and made a part hereof ("Real Property"); (4) Rights-of-Way and Permits appurtenant to or associated with the Pipelines as further described on Exhibits "C-1" through "C-4", attached hereto and made a part hereof; (5) The Assigned Contracts as further described on Exhibits "D-1" through "D-4" attached hereto and made a part hereof; (6) Any and all pipe, pumps, motors, valves, fittings, miscellaneous equipment and facilities, and buildings associated with the Pipelines as further described on Exhibit "E-1" through "E-4" attached hereto and made a part hereof ("Equipment"); and (7) Books and Records. B. The Property shall not include any real or personal property interests described on the attached Exhibits "F-1" through "F-4" (the "Excluded Assets"). In particular, Seller is not selling to Buyer any of its allowance oil or other oil held in inventory for Seller in any of the Pipelines or in the assets of the Companies. For all of the Excluded Assets, Buyer grants Seller a sixty (60) day right of access, commencing on the Effective Date, to remove such assets, in a reasonable, safe and prudent manner, from the Property. C. Buyer acknowledges that it shall have no rights with respect to the use of the names "Equilon Pipeline Company LLC", "Shell Pipeline Company LP" or "Equilon Enterprises LLC dba Shell Oil Products US" or any and all variations and derivatives thereof, all trademarks, service marks and logos associated therewith, nor any "Goodwill" associated with any of the foregoing. Within sixty (60) days after the Effective Date, Buyer shall remove or cause to be removed, all such names, marks or logos from wherever they may appear on the Property, including the removal of all Equilon Pipeline, Shell Pipeline or Equilon Enterprises line markers. Article 2 Purchase Price A. Price. The price to be paid by Buyer to Seller for the Property shall be three hundred fifteen million dollars ($315,000,000.00) (the "Purchase Price") payable at Closing (as defined below) less the Earnest Money held by Seller, by wire transfer in immediately available funds to an account to be designated by Seller. B. Earnest Money. As evidence of Buyer's ability to perform this Agreement and good faith intent to comply with the terms hereof, Buyer has deposited with Seller an amount equal to five percent (5%) of the Purchase Price as Earnest Money (hereinafter "Earnest Money"). The Earnest Money shall accrue interest at a per annum rate calculated on a daily basis using the three month treasury bill rate published in The Wall Street Journal for any applicable day (with the rate for any day for which a rate is not published being the rate most recently published). All references to Earnest Money shall include interest on the Earnest Money as calculated by using the preceding sentence. If the transaction fails to close because any of the conditions to Closing in Section 3A. is not satisfied, Seller will refund the Earnest Money to Buyer and Buyer and Seller shall each be relieved of all further liability hereunder. Provided, however, if Buyer violates the terms of this Agreement and such violation is not cured by Buyer within 30 days following written notice of such violation from Seller to Buyer, Seller shall be entitled to retain the Earnest Money, as liquidated damages and not as a penalty. Provided further, however, if Seller violates the terms of this Agreement and such violation is not cured by Seller within 30 days following written notice of such violation from Buyer to Seller, Seller shall return the Earnest Money to Buyer and shall also pay Buyer an additional fifteen million dollars ($15,000,000.00), as liquidated damages and not as a penalty and Buyer and Seller shall each be relieved of all further liability hereunder. The Parties agree that if another owner in either of the Basin or Rancho pipeline systems attempts to delay Closing by claiming that it was owed a right of first refusal, Buyer will grant Seller a reasonable time to cure the delay. Article 3 Closing Closing shall take place on the first day of the month immediately following the month in which the waiting period(s) of the HSR Act expire at Seller's offices in Houston, Texas ("Closing"), or at such other time and place as agreed to in writing by the Parties. Control of operations, risk of loss, and transfer of title to the Property from Seller to Buyer shall be effective as of 7:00 a.m. local time on the Closing Date. 2 A. Conditions to Closing. Except as expressly waived by the Parties, the obligations of the Parties to close this transaction are subject to the complete satisfaction, prior to Closing, of each of the following conditions, which conditions the Parties intend to be conditions precedent to Seller's obligation to convey the Property and to Buyer's obligation to pay the Purchase Price: (1) All representations and warranties of the Parties set forth in this Agreement shall be true in all material respects as of the Closing Date as if made on the Closing Date, and the Parties shall have performed all covenants and conditions required by this Agreement to be performed at or prior to Closing and shall have taken all other actions reasonably necessary to close this transaction. (2) No Law shall exist or shall have been enacted restricting or substantially delaying this transaction. (3) Neither Party shall have exercised any right it may have to terminate or refuse to close under this Agreement. (4) If in the judgment of either Seller or Buyer, the pre-merger notification requirements of the HSR Act are applicable to this transaction, then both Seller and Buyer shall file with the Federal Trade Commission and the Department of Justice their respective Notification and Report Forms and any supplemental information, if any, and will comply with the requirements of the HSR Act. The respective obligations of the Parties to consummate this transaction are expressly made subject to satisfactory compliance with the HSR Act, including the expiration of any waiting period(s) required thereunder. (5) If applicable, each Party shall have complied with the requirements of federal and state securities Laws. (6) No Casualty Loss shall have occurred prior to Closing, unless Buyer notifies Seller that it is willing to close despite the Casualty Loss. The term "Casualty Loss" shall mean any single event of loss or damage to the Property or any portion thereof which causes a Material Adverse Environmental Condition or a Material Defect. (7) Each Party shall have received a certificate, dated as of the Closing Date, signed by the other Party's Secretary or Assistant Secretary certifying the incumbency of the officers executing this Agreement on behalf of such Party and any documents to be executed and delivered by it at the Closing. (8) Seller shall have executed and delivered to Buyer the Conveyance Documents. (9) Seller shall have paid to Buyer the Seller's portion of the property Tax in accordance with Section 6.B. B. If any condition or obligation of a Party has not been satisfied or waived, and Closing has not occurred by the close of business on the Closing Date, the Party to whom said obligation is owed may terminate this Agreement immediately upon the giving of written notice thereof to the Party owing such obligation. Buyer shall return all records, maps, files, papers, and other property of Seller then in its possession, and except as provided in Section 2(B), neither Party shall hereafter have any liability under this Agreement. This provision shall not, however, apply to limit the liability of a Party who has willfully caused termination hereof by any act or failure to act in violation of the terms and provisions of this Agreement. 3 Article 4 Allocation of Proceeds and Purchase Price A. All proceeds attributable to the operation, ownership, use or maintenance of or otherwise relating to the Property prior to the Effective Date shall be the property of Seller and to the extent received by Buyer or its Affiliates, Buyer shall promptly and fully disclose, account for and transmit same to Seller. All proceeds attributable to the operation, ownership, use, or maintenance of or otherwise relating to the Property on and after the Effective Date shall be the property of Buyer and to the extent received by Seller or its Affiliates, Seller shall promptly and fully disclose, account for and transmit same to Buyer. B. The Purchase Price for the Property shall be allocated by the Parties' mutual agreement prior to the Closing Date in substantially the same form attached hereto as Exhibit "G" which will represent a reasonable determination in good faith of the fair market value of the Property. Buyer and Seller agree that they shall use these allocations to prepare, on a consistent basis, and file as required, Form 8594 (Asset Acquisition Statement) under Section 1060 of the Code. Article 5 Responsibility For Contractual Payments and Obligations A. Seller shall be responsible for all rentals, contractual payments, compensation owed to employees, operating costs, expenses, fees, vendor and contractor invoices, billings, charges, assessments and other indebtedness and obligations arising from the ownership, operation, use or maintenance of the Property prior to the Effective Date. Buyer shall be responsible for all such payments and obligations arising from the ownership, operation, use or maintenance of the Property on and after the Effective Date. Seller shall be responsible for all Taxes arising from the ownership, operation, use or maintenance of the Property on or before the Closing Date, and Buyer shall be responsible for all Taxes arising from the ownership, operation or maintenance of the Property after the Closing Date. As of the Effective Date (or in the case of Taxes, after the Closing Date) Buyer shall assume and perform all obligations and implied covenants of Seller relating to the Property (whether such obligations are to a grantor, a governmental body or any other Person) to the extent the same are attributable to periods of time on and after the Effective Date (or in the case of Taxes, after the Closing Date), including, but not limited to, any obligations arising with respect to the abandonment, or removal (as the case may be) of any existing facilities, Pipeline, appurtenant or associated equipment or other personal property located on or included in the Property; provided, however, such assumed obligations shall exclude, and Seller agrees to retain and perform all obligations relating to the Property to the extent the same arise out of any Contracts which are not described on Exhibits "D-1" through "D-4" hereto, all obligations that relate to the Excluded Assets, and all obligations of Seller under Article 12 hereof. For clarification, the obligations of Seller under this Article 5 shall not be subject to or governed by Article 12 or Article 13. B. To the extent utilities have not been placed in Buyer's name as of the Effective Date, charges and credits for water, electricity, sewage, gas, and all other utilities shall be adjusted and apportioned between Seller and Buyer through the Effective Date. 4 Article 6 Taxes and Related Matters A. Cooperation. Buyer and Seller agree to furnish, or cause to be furnished, to each other, upon request, as promptly as practicable, such information and assistance relating to the Property as is reasonably necessary for the filing of all Tax returns, the preparation for any audit by any taxing authority, and the prosecution or defense of any Proceeding relating to any Tax return. Seller and Buyer shall cooperate with each other in the conduct of any audit or other Proceeding related to Taxes involving the Property and each shall execute and deliver such documents as are necessary to carry out the intent of this article. Seller and Buyer agree to file such reports, certificates or returns, and provide such evidence of the applicability of exemptions, as are reasonably requested by the other Party or are required under federal, state, local, foreign or other applicable law in order to reduce or eliminate any Taxes attributable to the transaction contemplated by this Agreement. B. Property Taxes. For purposes of this Agreement, general property Taxes in respect to the ownership or use of the Property for the calendar year in which the Closing Date occurs shall be prorated between Buyer and Seller as of the Closing Date regardless of when such general property Taxes are actually billed and payable. At Closing, Seller shall pay to Buyer Seller's share of such general property Taxes attributable to the period on or prior to the Closing Date, using estimates to the extent such general property Taxes have not been billed or are not determinable as of the Closing Date (such estimates are to be based upon (i) such Taxes for the prior year and (ii) to the extent there were no such Taxes for the prior year for any portion of the Property, a fair market valuation of the portion of the Property for which there were no such Taxes for the prior year multiplied by the applicable property Tax rates for the prior year, except in either case that appraised values for the current year, regardless of whether final, and property Tax rates adopted for the current year shall be utilized to the extent available as of the Closing Date). Buyer shall actually pay to the taxing authority all general property Taxes for the year of Closing. Notwithstanding anything in this Agreement to the contrary, no further adjustment shall be made for such general property Taxes, and Buyer hereby agrees to assume the payment of all such general property Taxes effective upon Closing. C. Documentary Transfer Taxes. Buyer shall pay and bear all documentary transfer Taxes that may be required in connection with the purchase and sale of the Property. Seller shall pay or indemnify Buyer for any such Taxes incurred in connection with the transfer of any Property by Seller to the Companies (which indemnity shall survive Closing and not be subject to any deductible or cap under this Agreement). D. Other Transfer Taxes. Buyer shall pay and be responsible for any other applicable transfer Taxes incurred in connection with the purchase and sale of the Property, including, without limitation, any federal, state or local sales, use, or excise Taxes, whether levied on Seller or Buyer. Buyer shall be responsible for, and will file all necessary Tax returns and other documentation with respect to all such Taxes and remit, upon the request of Seller, copies of the portions of such returns relevant to this Agreement and any necessary documentation to Seller. Seller shall pay or indemnify Buyer for any such Taxes incurred in connection with the transfer of any Property by Seller to the Companies (which indemnity shall survive Closing and not be subject to any deductible or cap under this Agreement). E. Confidential Tax Information. After giving full effect to Article 6A, notwithstanding anything to the contrary in this Agreement, neither Party shall be required at any time to disclose to the other Party, or to any other Person, absent legal constraint, any Tax return or other confidential Tax information. 5 F. Deferred Like-Kind Exchange Cooperation. If so requested by Seller, Buyer shall, at no cost or obligation to Buyer, reasonably cooperate in structuring and completing all or a portion of this transaction for Seller so as to effect a disposition of "relinquished property" in connection with a multiple party deferred like-kind exchange pursuant to Section 1031 of the Code. In particular, Buyer hereby consents to the assignment of an interest in the Property to a "qualified intermediary" prior to the Closing hereunder and the assignment by Seller to such "qualified intermediary" of Seller's right to receive the Purchase Price hereunder. Buyer, however, shall not be required to act as a "qualified intermediary." The terms "replacement property," "qualified intermediary," and "relinquished property" as used herein shall have the meanings ascribed to them in Treasury Regulations Section 1.1031(k)-1. Seller shall indemnify Buyer against any Claim arising out of any transaction or action incidental or related to the matters contemplated by this Section 6.F., which indemnity shall survive Closing. No transaction or action contemplated by this Section 6.F shall result in delaying the Closing to a date later than the date on which it otherwise would have occurred. Seller's indemnity under this Section 6.F shall not be subject to any deductible or cap notwithstanding any other provision of this Agreement. G. Allocation of Taxable Income to Periods Before and After Closing Date. Seller (or if applicable a Person or Persons owning a direct or indirect interest in Seller) shall include in its federal Tax return, and its state Tax returns for those states that follow the federal rules, any item of income, gain, loss, deduction and credit with respect to activities of the Companies or Property on or prior to the Closing Date. Seller (or if applicable a Person or Persons owning a direct or indirect interest in Seller) shall pay or cause to be paid all Taxes shown as due (or required to be shown as due) on such Tax returns. Buyer shall include the income, gain, loss, deduction and credit with respect to activities of the Companies after the Closing Date, in either (i) its own federal income Tax return, and in its own state income Tax returns for those states that follow the federal rules or (ii) in federal and state income Tax returns filed by an affiliate or affiliates of Buyer. Seller shall make no election or otherwise take any action to cause the Companies to be treated as associations under Treasury Regulation sections 7701-2 and 7701-3, and shall pay, and indemnify Buyer for (which indemnity shall survive Closing and not be subject to any deductible or cap under this Agreement), any Taxes required to be paid by the Companies attributable to the treatment of either of the Companies as an association. Both the Buyer and Seller recognize that the Texas franchise privilege period pertaining to the Companies does not end at the Closing Date. Therefore, Seller will provide Buyer with all required Tax attributes pertaining to the period prior on or prior to the Closing Date for inclusion into the Tax return to be filed for the Companies by Buyer that includes such Tax attributes in the calculation of the franchise Tax. Seller will be responsible, and will reimburse Buyer, for all increased Taxes paid by Buyer or the Companies, relating to Tax attributes generated on or prior to the Closing Date in any such Texas franchise Tax return. H. Sale of the Companies Treated as Asset Sale for Income Tax Purposes. The sale of the partnership interests in the Companies shall be treated for federal income tax purposes, and for state income tax purposes in those states that follow the federal rules, as a sale of the underlying assets of the Companies in exchange for the Purchase Price at the Closing Date. I. Occasional Sale. This purchase and sale constitutes an isolated or occasional sale and is not subject to sales or use tax with any of the taxing authorities having jurisdiction over this transaction, and no sales tax need be collected by Seller from Buyer at Closing. Seller agrees to cooperate with Buyer in demonstrating the requirements for an isolated or occasional sale or that other sales tax exemptions have been met. 6 J. Certification of Non-Foreign Status. Seller shall provide to Buyer prior to Closing a certification of non-foreign status as described in Treasury Regulation section 1.1445-2(b)(2).

Enter all or part of the Property with Seller's representative, including all or any easements, to view the Pipelines, facilities, Equipment, and other operations conducted thereon prior to Closing, and to conduct a surface only inspection and assessment, inventory, study and examination of the same, independently of any documents, data or information furnished by Seller hereunder; and 2. Inspect and review the Books and Records, including all non-privileged files, records, documents and data related to the above matters, including, but not limited to, pipeline maintenance and construction records. Buyer acknowledges that it shall not have access to Seller's Pipeline Manuals used in the operation of the Pipelines, which are considered by Seller to be proprietary property. Buyer shall not have the right to perform any phase II environmental assessments. B. Except as required by Law, all information acquired by Buyer in any inspection, inventory, study, or examination of the Property, and the results of any analysis thereof, shall be kept confidential by Buyer from anyone other than Seller or Buyer's representatives in accordance with Buyer's executed Confidentiality Agreement.

To be effective, any such notice shall specifically identify and describe the basis for such termination, and shall include substantiating evidence thereof. Minor deviations in the location of a pipeline relative to a defined right-of-way in an easement or encroachments on the right of way shall not be deemed to constitute a Material Defect for purposes of this Agreement.

Notwithstanding the above, if Buyer can provide substantiating evidence that the Property is subject to Material Adverse Environmental Conditions or Material Defects that, when totaled together, would expose Buyer to costs to remedy or cure, or the potential for exposure for claims, damages, penalties assessments or costs in excess of ten percent (10%) of the Purchase Price, Buyer, in its sole discretion, may terminate this Agreement. G. If Seller agrees to remedy any specific Material Adverse Environmental Condition or Material Defect in the Property, then all negotiations and contacts with state, federal and local agencies for approval and review of such remedial action shall be made by Seller, and Buyer shall make no independent contacts with any of the agencies relative to such remedial action. Buyer shall receive copies of all correspondence between Seller and any agencies regarding such remedial action. Article 11 Title A. At Closing, Seller shall grant, transfer, assign, convey, and deliver to Buyer or the Companies, and Buyer shall accept from Seller, by means of a Special Warranty Deed, and other Conveyance Documents, good and marketable title to the Property, free and clear at Closing of any lawful claims of any third party claiming by, through or under Seller, but not otherwise. B. This Agreement is expressly conditioned upon Buyer's approval of Seller's title to, ownership of, interest in, and right to possess the Property. During the period commencing on the date of this Agreement and ending twenty (20) days before Closing ("Title Examination Period"), Buyer and its Affiliates and their employees, agents and contractors shall have full access to and the right (subject to the executed Confidentiality Agreement) to examine all of Seller's records relating to the Property, including but not limited to, those listed on Exhibits "C-1" through "C-4" attached hereto, for all purposes related to this transaction. C. On or before the last day of the Title Examination Period, Buyer shall give Seller written notice of the land and property interests included in the Property which have a Significant Title Defect. Minor deviations in the location of a Pipeline, relative to a defined Right-of-Way in an easement, shall not be deemed to constitute a Significant Title Defect for purposes of this Agreement. If any 12 Significant Title Defect cannot be or is not cured by Seller during the period commencing upon the date of this Agreement and ending on or before the Effective Date, Buyer may, at its election: (1) terminate this Agreement without further obligation or liability by giving written notice to Seller any time prior to Closing; (2) offer to acquire the Property, including the portion affected by the Significant Title Defect, subject to the terms of this Agreement, but at a reduced Purchase Price, which offer Seller may accept or reject in its sole discretion; or (3) acquire the Property, including the portion affected by the Significant Title Defect, without adjustment to the Purchase Price. Article 12 Seller's Responsibility for Claims Relating to the Property A. Seller's Environmental Responsibilities shall be as follows: (1) (a) Ongoing Remediation Sites. Seller agrees to retain full responsibility for all costs, including capital, operating and maintenance costs, incurred in connection with (i) any investigation or monitoring of Environmental Conditions or (ii) any clean-up, remedial, removal or restoration work of those Environmental Conditions, either of which is ongoing on the Closing Date and that is required by any federal, state or local governmental agency or political subdivision with applicable jurisdiction because of the presence, suspected presence, release or suspected release of a Hazardous Substance in the air, soil, surface water, or groundwater on or emanating from the Property (hereinafter the "Ongoing Remedial Work"). The Ongoing Remedial Work is listed in Section 12A. of the Disclosure Statement. The performance of Ongoing Remedial Work will be by the Seller, in the name of the Seller. The Seller will obtain all necessary licenses, manifests, permits and approvals to perform such work. All Ongoing Remedial Work and the disposal of all waste generated by the Ongoing Remedial Work will be performed in accordance with all applicable Laws. Buyer grants to Seller, at no cost to Seller, ingress, egress, access to and use of lands (including land farming activities) and utilities, including but not limited to, electricity and water, as needed by Seller to complete any of the remedial activities described in Section 12A. (1)(a). Seller's responsibility for sites listed in Section 12A of the Disclosure Schedule shall terminate upon Seller's receipt from the applicable regulatory agency of one of the following: (i) concurrence that remediation efforts are complete and the site may be closed; (ii) No Further Action Required letter; or (iii) concurrence with the results of Seller's Risk Based Corrective Action Plan. For releases that were less than the regulatory reporting threshold at the time of the release, Seller's responsibility for these sites would terminate when laboratory results indicate contamination concentrations are below agency clean up requirements. Seller will conduct all communications concerning Seller's remediation activities with all regulatory agencies having jurisdiction. Seller will provide Buyer copies of all correspondence with the applicable regulatory agency concerning Seller's active remediation sites, but Buyer is prohibited from communicating with the regulatory agency concerning Seller's remediation activities. (b) Subsequent Spill on Ongoing Remediation Site. Should Buyer have a reportable release that adversely impacts or affects Seller's Ongoing Remedial Work, then Seller will transfer to Buyer the net present value of the unexpended dollars remaining in the budgeted amount as listed in Section 12A of the Disclosure Schedule for the specific Ongoing Remedial Work at the site where Buyer's release occurred. Buyer shall thereafter assume full responsibility for the Ongoing Remedial Work at the specific site along with the remediation of Buyer's own 13 release. Buyer shall immediately indemnify Seller for anything relating to the particular Ongoing Remedial Work under Sections 13A.(2) or 13C. (2) Environmental Insurance. Seller will provide Buyer (at Seller's expense) with an environmental insurance policy which will provide the following coverages: (i) On-Site Clean Up of Unknown Pre-Existing Conditions (Coverage A), (ii) Third Party claims for On-Site Bodily Injury and Property Damage arising from Unknown Pre-Existing Conditions (Coverage C), (iii) Off-Site Clean Up of Unknown Pre- Existing Conditions (Coverage D) and (iv) Third Party claims for Off-Site Bodily Injury and Property Damage arising from Unknown Pre-Existing Conditions (Coverage F). The Buyer (and its general partner and Affiliates) as well as the Seller will be named as named insureds under such policy. The limit of liability will be $70,000,000 each incident/coverage section aggregate, with a deductible of $100,000 each incident aggregated at $1,000,000 and having a $10,000 maintenance deductible each incident thereafter. In addition, the policy will include environmental cost cap insurance to include coverage for Clean-Up costs from identified pollutants within the Remediation Plan and pollutants different than those in the Remediation Plan with a limit of $5,000,000 each incident and in the aggregate applying to the Ongoing Remedial Work for the benefit of Seller. The policies will have a ten (10) year coverage term, with policy inception being the transaction closure date. Specific coverage details may be reviewed within the insurance policy provided at or within a reasonable period prior to Closing. A specimen of such policy is attached hereto as Exhibit L. (3) Post Closing Assessment. Buyer is prohibited (for purposes of this Agreement) from conducting post closing environmental assessments, except in those cases where a reasonably prudent pipeline operator, not afforded the indemnities and insurance provided in this Agreement, would conduct such assessments in the ordinary course of business or where required by a regulatory agency having jurisdiction as a result of a post Closing release on the Property. Should Buyer conduct a post Closing environmental assessment (i) which is not in accordance with the provisions of the environmental insurance policy referred to in Section 12A(2) of this Agreement, (ii) in a case where a reasonably prudent pipeline operator, not afforded the indemnities and insurance provided in this Agreement, would not conduct such an assessment in the ordinary course of business or (iii) where not required by a regulatory agency having jurisdiction as a result of a post Closing release on the Property, the Buyer shall indemnify, defend, and hold harmless the Buyer Indemnitees from any and all Claims arising out of such post Closing environmental assessment.

Seller shall have the right at all times to participate in the preparation for and conduction of any hearing or trial related to the provisions of this Article 13 for which it would receive indemnification, as well as the right to appear on its own behalf at any such hearing or trial. Any such participation or appearance by Seller shall be at its sole cost and expense. Article 14 Claims Procedure All claims for indemnification by a Party under Articles 12 or 13 (the Party claiming indemnification and the Party against whom such claims are asserted being herein called the "Indemnified Party" and the "Indemnifying Party", respectively) shall be asserted and resolved as follows. A. In the event that any Claim for which an Indemnifying Party would be liable to an Indemnified Party hereunder is asserted against or sought to be collected from such Indemnified Party by a Third Person, such Indemnified Party shall, within forty-five (45) calendar days of the receipt thereof, give notice (the "Claim Notice") to the Indemnifying Party of such Claim specifying the nature of and specific basis for such Claim and the estimated amount thereof, to the extent then feasible, which estimate shall not be binding upon the Indemnified Party in its effort to collect the final amount of such Claim. The failure to give any such notice shall not affect the rights of the Indemnified Party to indemnification hereunder unless the Indemnified Party has proceeded to contest, defend or settle the 17 Claim with respect to which it has failed to give prior notice to the Indemnifying Party. Additionally, to the extent the Indemnifying Party is prejudiced thereby, the failure to so notify the Indemnifying Party of any such Claim shall relieve the Indemnifying Party from liability that it may have to the Indemnified Party under the indemnification provisions contained in Article 12 or Article 13, as applicable, but only to the extent of the loss directly attributable to such failure to notify and shall not relieve the Indemnifying Party from any liability that it may have to the Indemnified Party otherwise. B. The Indemnifying Party shall be given the opportunity, at its cost and expense, to contest and defend, by all appropriate legal Proceedings, any Claim with respect to which it is called upon to indemnify the Indemnified Party under the provisions of this Agreement; provided, however, that notice of the intention to so contest and defend shall be delivered by the Indemnifying Party to the Indemnified Party within thirty (30) calendar days following receipt of the Claim Notice. If the Indemnifying Party does not give notice to the Indemnified Party of its election to contest and defend any such Claim within such period then the Indemnifying Party shall be bound by the result obtained with respect thereto by the Indemnified Party and shall be responsible for all costs incurred in connection therewith. The Claim which the Indemnifying Party elects to contest and defend may be conducted in the name and on behalf of the Indemnifying Party or the Indemnified Party as may be appropriate. Such Claim shall be conducted by counsel employed by the Indemnifying Party who shall be reasonably satisfactory to the Indemnified Party and the Indemnified Party shall have the right to participate in such Claim and to be represented by counsel of its own choosing at its own cost and expense. If the Indemnified Party joins in any such Claim, the Indemnifying Party shall have full authority to determine all action to be taken with respect thereto; provided that if the Indemnifying Party reserves its rights with respect to its indemnification obligations under this Agreement as to such Claim, then the Indemnified Party shall have full authority to determine all action to be taken with respect thereto. At any time after the commencement of defense of any Claim, the Indemnifying Party may request the Indemnified Party to agree in writing to the abandonment of such contest or to the payment or compromise by the Indemnifying Party of the asserted Claim provided the Indemnifying Party agrees in writing to be solely liable for all Losses relating to such Claim, whereupon such action shall be taken unless the Indemnified Party determines that the contest should be continued and notifies the Indemnifying Party in writing within fifteen (15) calendar days of such request from the Indemnifying Party. In the event that the Indemnified Party determines that the contest should be continued, the amount for which the Indemnifying Party would otherwise be liable hereunder shall not exceed the amount which the Indemnifying Party had agreed to pay in payment or consideration of such Claim, provided the other Party to the contested Claim had agreed in writing to accept such amount in payment or compromise of the Claim as of the time the Indemnifying Party made request therefor to the Indemnified Party, and further provided that under such proposed compromise, the Indemnified Party would be fully and completely released from any further liability or obligation with respect to the matters which are the subject of such contested Claim. C. If requested by the Indemnifying Party, the Indemnified Party agrees, at the Indemnifying Party's expense, to cooperate with the Indemnifying Party and its counsel in contesting any Claim that the Indemnifying Party elects to contest, or, if appropriate and related to the Claim in question, in making any counterclaim against the Person asserting the Third Person Claim, or any cross-complaint against any Person other than an Affiliate of the Indemnified Party. D. If any Indemnified Party should have a Claim against the Indemnifying Party hereunder that does not involve a Claim being asserted against or sought to be collected from it by a Third Person, the Indemnified Party shall send a Claim Notice with respect to such Claim to the Indemnifying Party. If 18 the Indemnifying Party disputes such Claim, such dispute shall be resolved in the manner set forth in Article 35 hereof. E. The Indemnified Party agrees to afford the Indemnifying Party and its counsel the opportunity, at the Indemnifying Party's expense, to be present at, and to participate in, conferences with all Persons asserting any Claim against the Indemnified Party and conferences with representatives of, or counsel for, such Persons. F. Upon payment of the amount of any loss, liability, lien, encumbrance, damage, judgment, demand, suit, claim, assessment, charge, fine, penalty or expense (including attorneys' fees and other costs of litigation) by the Buyer pursuant to this Agreement, the Seller shall assign to the Buyer and subrogate the Buyer to, without payment of any further consideration, all rights and remedies of the Seller in respect of the payment and shall provide all reasonable cooperation and assistance required by the Buyer in making and prosecuting a claim for recovery against any Person to the extent that payment is made by Buyer. Seller may not take any action to impair any such right or remedy of Buyer to recover any such payment made by Buyer. By way of clarification, the provisions of this Section 14F shall apply (without limitation) to amounts paid by Buyer pursuant to Articles 5, 13, 14 and 15. Article 15 Incidental Contamination and NORM Buyer acknowledges that the Property may contain inter alia asbestos in pipe coating, undisplaced petroleum hydrocarbon products in pipelines, coats of lead-based paints, PCB's in transformers, mercury in electrical switches, and Naturally Occurring Radioactive Material ("NORM").

Article 16 Tariffs and Allocation of Carrier Obligations and Proceeds A. Buyer agrees that, for a Pipeline which has tariffs on file with a regulatory agency, it will either adopt the Seller's tariff or file its own to be effective as of the Effective Date, if required by law to do so. If there is a protest regarding Seller's cancellation of its tariff, as between Seller and Buyer, Buyer will manage and direct the response to the protest with Seller's cooperation. Seller will be responsible for all regulatory agency and Third Person contacts. B. The Pipelines contain crude oil which is held for the account of shipper(s). It is understood that title to the contents of the Pipelines will remain with the shipper(s) and that Buyer assumes the obligation to handle such contents in accordance with applicable published tariff provisions. Further, to 19 the extent that such crude oil has been tendered for shipment in the Pipelines under an applicable published tariff, but not yet delivered, Buyer shall receive that crude oil for transportation in accordance with applicable published tariffs.
