Each of the Reporting Persons acquired beneficial ownership of the Units solely for investment purposes. In the future, each of the Reporting Persons may, directly or indirectly, acquire or dispose of additional Units, either through open market or privately negotiated transactions.

The Class B Units are not currently convertible into Common Units. However, at any time, any holder of Class B Units has the right to require the Partnership to use its reasonable best efforts to submit to a vote of its securityholders the approval of a change in the terms of the Class B Units to provide that each Class B Unit is convertible at any time into one Common Unit at the option of the holder of such Class B Unit.

The Subordinated Units are not currently convertible into Common Units. However, if certain performance thresholds over certain time periods as set forth in the Partnership's limited partnership agreement are met, then the Subordinated Units shall convert into Common Units.

(b)     None of the Reporting Persons has the sole power to vote or to direct the vote of, or to dispose or direct the disposition of, any Units.

On June 8, 2001, PAAI LLC sold 5,215,401 Subordinated Units at a purchase price of $22.00 per Subordinated Unit pursuant to certain unit transfer agreements (collectively, the "Unit Transfer Agreements") by and among the Reporting Persons and certain purchasers. On June 8, 2001, Plains contributed 287,500 Subordinated Units to Plains AAP, L.P., a Delaware limited partnership ("Plains AAP"), pursuant to a letter agreement among Plains, Plains AAP and the other parties thereto. On June 8, 2001, in connection with the consummation of the transactions contemplated by the Unit Transfer Agreements, PAAI transferred 150,808 Common Units to certain employees in connection with the vesting of such Common Units pursuant to certain transaction grant agreements and 15,000 Common Units to certain directors of PAAI in connection with the vesting of such Common Units pursuant to the terms of the PAAI 1998 Long Term Incentive Plan.

                    WHEREAS, prior to the Closing Date, PAAI was the sole general partner of the MLP and certain affiliates of the MLP;

                    WHEREAS, prior to the Closing Date, PAAI has, among other actions, formed the Successor GP pursuant to the Delaware Limited Liability Company Act and in connection with the Contribution Agreement, all of the property used in the trade or business of PAAI as general partner of the MLP will be transferred to the Successor GP;

                    WHEREAS, in connection with the Contribution Agreement, all of the property used in the trade or business associated with the headquarter employees described in Section 1(a)(ii) of this Agreement will be transferred by Parent to the Successor GP;

                    WHEREAS, in connection with the Contribution Agreement, the Successor GP will succeed to the management and business activities formerly performed by PAAI;

                    WHEREAS, pursuant to Section 5.10(a) of the Contribution Agreement, as of the Closing Date, Parent, PAAI and the Successor GP shall (i) identify the headquarter employees of Parent engaged in the business of managing the MLP that will be transferred to the Successor GP and (ii) provide for the immediate transfer of employment of such headquarter employees and the immediate transfer of all of the current employees of PAAI to the Successor GP (collectively, the "Transferred Employees") and make such arrangements as are necessary with respect to compensation and employee benefit plans for Transferred Employees, all as immediately as practicable;

                    WHEREAS, pursuant to Section 5.10(a) of the Contribution Agreement, as of the Closing Date, Parent, PAAI and the Successor GP are to determine the treatment of obligations and liabilities under certain employee benefit plans in which Transferred Employees participate and enter into any transition services arrangements deemed necessary by the parties for a period of no more than three months following the Closing Date;

                    WHEREAS, Parent, PAAI and the Successor GP desire to set forth their obligations and liabilities with respect to Transferred Employees and to establish necessary transition services arrangements for Transferred Employees; and

                    WHEREAS, this Agreement is being executed simultaneously with the Closing of the Contribution Agreement.

                    NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein, the parties hereto agree as follows:

                    Section 1.  Transferred Employees' Covenants.

(a)     Transferred Employees. The Transferred Employees shall include (i) all of the employees employed by PAAI immediately prior to the Closing Date and (ii) the headquarter employees employed by Parent immediately prior to the Closing Date who perform services related to the business of managing the MLP and are identified on Schedule A attached hereto.
(b)     Employment Agreements. Effective as of the Closing Date, the Successor GP will assume the obligations under the employment agreements between Parent and Greg Armstrong dated March 1, 1993, as amended, and between Parent and Harry Pefanis dated November 23, 1998, in accordance with the amendment and restatement of such employment agreements as approved by the Board of Directors of PAAI as sole member of the Successor GP.
(c)     Transition and Retention Bonuses. The transition bonuses approved by the Compensation Committee of Parent on May 7, 2001 for certain Transferred Employees will be paid by Parent to each such Transferred Employee for the account of the Successor GP as soon as practicable following the date such bonuses are earned. In addition, any portion of the retention bonus under the Parent's retention bonus program announced to employees in December 2000 with respect to a Transferred Employee that is unpaid as of the Closing Date will be paid by Parent to each such Transferred Employee for the account of the Successor GP as soon as practicable following the date such bonus is earned in accordance with the retention bonus program. Parent shall grant each Transferred Employee credit for service with the Successor GP for all purposes under the Parent's retention bonus program.
(d)     1996 Stock Incentive Plan.
	(i)     With respect to options granted to Transferred Employees (who are not key employees described in Section 1(d)(ii) below) under Parent's 1996 Stock Incentive Plan that are unvested and forfeitable as of the Closing Date, each such Transferred Employee shall receive an amount of cash equal to the difference between (A) the average of the closing sales prices on the American Stock Exchange of the Parent stock for the five trading days immediately preceding the date hereof and (B) the option exercise price of such options, multiplied by the number of unvested shares subject to such options. Such amount shall be paid by Parent as soon as practicable following the Closing Date.
	(ii)    With respect to options granted to certain key Transferred Employees (identified on Schedule B attached hereto) under Parent's 1996 Stock Incentive Plan that are unvested on the Closing Date, PAAI shall grant, and the Successor GP shall assume administrative responsibility for, phantom equity awards payable in subordinated units of the MLP (or, to the extent such subordinated units have been converted into common units, payable in common units) comparable in value to such options and subject to the same vesting schedule as such options. The number of subordinated units of the MLP subject to such phantom equity awards shall be determined for each such Transferred Employee by (A) multiplying the difference between (1) the average of the closing sales prices on the American Stock Exchange of the Parent stock for the five trading days immediately preceding the date hereof and (2) the option exercise price of such options, by the number of unvested shares subject to such options, and (B) dividing the result in clause (A) by $22.00, rounded up to the nearest whole unit. Such phantom equity awards shall provide for distribution equivalent rights ("DERs"), i.e., the right to receive the cash equivalent of any distributions made with respect to a subordinated unit during the period from the Closing Date and prior to the vesting of such phantom equity award, that shall be payable in cash on the vesting of the applicable phantom equity award. Parent shall, or shall cause its Affiliates to, deliver to each such Transferred Employee for the account of the Successor GP on or prior to vesting such number of subordinated units of the MLP subject to phantom equity awards and cash equal to the DERs as determined above in accordance with the vesting schedule of such phantom equity awards. Documents evidencing such grants shall be delivered as soon as practicable after the Closing Date.
(e)     Officers' Retirement Plan. The vesting service for each of the Transferred Employees with a Deferred Compensation Agreement on the date hereof is set forth in Schedule C attached hereto.

In consideration of the receipt of the amounts described in the foregoing provisions of this clause (e), each Transferred Employee shall agree to relinquish all rights with respect to such Transferred Employee's Deferred Compensation Agreement .
(f)     Long-Term Incentive Plan. Effective as of the Closing Date, the Successor GP shall assume the PAAI 1998 Long-Term Incentive Plan and all outstanding awards granted thereunder that are unvested as of the Closing Date on the same terms and conditions. All non-employee director awards will vest on the date hereof in accordance with their terms. Such director awards shall be paid by PAAI or its Affiliates in accordance with the terms of the plan as soon as practicable following the date hereof and PAAI shall be reimbursed by the MLP for such payments in accordance with the MLP Partnership Agreement. Except with respect to such director awards, Parent and PAAI shall have no future liability with respect to such plan and such unvested awards; provided, however, that the parties hereto acknowledge that the Successor GP, upon vesting of such awards, may seek to satisfy such awards by the purchase of common units of the MLP directly or indirectly from Parent or PAAI.
(g)    Qualified Retirement Plans.
	(i)     Parent 401(k) Plan.
	(A)     As soon as practicable after the date hereof, the Successor GP shall establish or designate, and maintain, a qualified defined contribution plan (the "Successor 401(k) Plan") to provide benefits to the Transferred Employees who, on the Closing Date, are participants in the Parent 401(k) Plan ("Plan Participants") which are substantially equivalent to the benefits provided to participants under the Parent 401(k) Plan (provided, however, that all matching contributions may be paid in cash). The Successor 401(k) Plan shall be qualified under Sections 401(a) and 401(k) of the Code and shall provide the Plan Participants credit for service with Parent and its affiliates (including PAAI) and their respective predecessors prior to the Closing Date for all purposes for which service was recognized under the Parent 401(k) Plan.
	(B)     As soon as practicable after the filing of the determination letter request described in clause (C) below, Parent shall cause the trustee of the Parent 401(k) Plan to transfer to the trust forming a part of the Successor 401(k) Plan cash or assets in which Plan Participants are currently invested (or with respect to participant loans granted prior to the Closing Date, if any, such loans and any promissory notes or other documents evidencing such loans) in an amount equal to the account balances of Plan Participants as of a valuation date (the "Valuation Date") not more than 60 days preceding the date of transfer, increased by any contributions due for periods prior to the Closing Date and not made as of the Valuation Date, reduced by any benefits paid during the period following such Valuation Date to the date of transfer, and adjusted for any investment earnings or losses during the period following such Valuation Date to the date of transfer (the "Account Balances").
	(C)     No later than 60 days after the Closing Date, the Successor GP shall file a request for a determination letter with the IRS that the Successor 401(k) Plan and related trust satisfy the requirements for qualification under Sections 401(a) and 401(k) of the Code. The Successor GP agrees that it shall amend the Successor 401(k) Plan in any respect as may be required by the IRS in order to receive a favorable determination letter from the IRS that the Successor 401(k) Plan and related trust satisfy the requirements for qualification under Sections 401(a) and 401(k) of the Code. No transfer shall be made unless the Successor GP files with the IRS the request for determination letter referred to in this clause (C).
	(D)     In consideration of the agreements of Parent contained in clauses (B) and (C) of this Section 1(g)(i), the Successor GP shall, effective as of the Closing Date, assume all of the liabilities and obligations of Parent and its affiliates in respect of the Plan Participants and their beneficiaries under the Parent 401(k) Plan, and Parent and its affiliates and the Parent 401(k) Plan shall, except to the extent set forth in this Agreement, be relieved of all liabilities and obligations to the Plan Participants and their beneficiaries arising out of the Parent 401(k) Plan.
	(ii)     Permian Plans. Effective as of the Closing Date, the Successor GP acknowledges and agrees that it shall take all actions necessary to assume the responsibilities and activities formerly performed by Parent and PAAI with respect to the administration of the Permian Corporation Savings Plan and Permian Corporation Retirement Plan.

(i)     The Successor GP Plans. No later than the end of the Transition Period (as defined below): (i) the Successor GP shall establish, for the benefit of the Transferred Employees, employee benefit plans (the "Successor GP Plans") that will provide benefits comparable to those provided to the Transferred Employees under the Parent Plans identified in Schedule D hereto, and (ii) the Transferred Employees will be participants in the Successor GP Plans to the extent that any such Transferred Employees were participants in the Parent Plans during the Transition Period.

                    Section 4.  Standard of Services.

          (b)     The Successor GP shall make available to Parent on a timely basis all data, information and other materials within its control that are reasonably necessary for Parent to perform, or cause to be performed, the Transition Services. The parties hereto agree that Parent shall have no liability for any failure to perform or for the late performance of any of the Transition Services to the extent such non-performance or late performance results from having failed to provide, or cause be provided to, Parent, the data, information or other materials required to perform the Transition Services.

          (c)     Parent shall (i) maintain records regarding Transition Services in the same manner that it has kept records for itself prior to the date hereof, and (ii) provide the Successor GP with reasonable access to such records.

In addition, employee benefits and compensation costs and reimbursements with respect to services provided by Parent's Environmental Health and Safety Manager to the Successor GP shall be payable by the Successor GP under this Agreement consistent with past practice of such employee's provision of services to PAAI.

                    Section 6.  Covenants.

                    Section 7.  Independent Contractor. Parent shall not have any responsibility with respect to the management or operation of the business being transferred to Successor GP, and its responsibilities shall be limited to providing the Transition Services described herein. Parent shall provide the Transition Services as an independent contractor only, and this Agreement does not and shall not be construed as creating a joint venture, partnership or agency relationship between the parties.

                    Section 8.  Indemnification.

          (a)     Indemnification by Parent and PAAI.
