[FORM OF INTEREST CALCULATION AGENCY AGREEMENT]

INTEREST CALCULATION AGENCY AGREEMENT

     INTEREST CALCULATION AGENCY AGREEMENT between MGE ENERGY, INC. (the
“Issuer”) and                      (“                    ”) dated as of                                , 2003.

PRELIMINARY STATEMENT

     1.     The Issuer proposes to issue and sell its Medium-Term Notes due from
Nine Months to 30 Years from Date of Issue (the “Notes”) from time to time
under, and pursuant to, the terms of an Indenture (the “Indenture”), dated as
of                                , 2003 between the Company and                     , as Trustee (in
such capacity, the “Trustee”). Capitalized terms not otherwise defined herein
shall have the meanings assigned to them in the Indenture and if not defined
therein then as defined in the Prospectus and Prospectus Supplement relating to
the Notes.

     2.     The Issuer desires to appoint an agent of the Issuer to calculate the
base rates applicable to those Notes on which interest is to accrue, at any
time, at a variable or floating rate (“Floating Rate Notes”), determined by
references to the Commercial Paper Rate, LIBOR, the Prime Rate, the Treasury
Rate or other interest rate basis as is set forth in a pricing supplement
(collectively, the “Base Rates”) as are specified and described in the Floating
Rate Notes.

     NOW, THEREFORE, the Issuer and hereby agree as follows:

     SECTION 1. APPOINTMENT OF CALCULATION AGENT. The Issuer hereby appoints
[                    ] as Calculation Agent (in such capacity, the “Calculation Agent”)
of the Issuer with respect to any Floating Rate Notes to be issued by the
Issuer under and pursuant to the terms of the Indenture, and the Calculation
Agent hereby accepts its obligations as set forth in this Agreement upon the
terms and conditions set forth herein.

     SECTION 2. CALCULATION OF BASE RATES. The calculation date (the
“Calculation Date”) for each applicable Interest Determination Date for any
Note shall be the earlier of (i) the tenth calendar day after such Interest
Determination Date or, if any such day is not a Business Day, the next
succeeding Business Day and (ii) the Business Day preceding the applicable
Interest Payment Date or date of Maturity, as the case may be. The Calculation
Agent shall notify the Issuer and the Trustee of the applicable interest rate
on or prior to each such Calculation Date.

     If at any time the Calculation Agent is not also acting as Trustee under
the Indenture, the Issuer shall, upon the issuance of each Floating Rate Note
having a different Base Rate or different Interest Determination Dates than the
Base Rate or Interest Determination Dates for any prior Floating Rate Note,
notify such Calculation Agent of such Interest Determination Dates and the
applicable interest rate base(s) or formula for such Floating Rate Note.

 

 

     SECTION 3. NEW BASE RATES. If the Issuer proposes to issue Floating Rate
Notes whose interest rate will be determined on a basis or formula not referred
to above (a “New Base Rate”), the Issuer shall give a description of such New
Base Rate to the Calculation Agent. The Calculation Agent shall determine if
it is able and willing to calculate the New Base Rate and upon its agreement in
writing to do so the term “Base Rate’’ shall be deemed to include the New Base
Rate. If the Calculation Agent notifies the Issuer that it is not able or
willing to calculate the New Base Rate, or that it is only willing to do so on
the basis of an increase of its fees not acceptable to the Issuer, the
Calculation Agent shall have no responsibility with respect to such New Base
Rate and the Issuer shall appoint a different calculation agent to determine
the New Base Rate.

     SECTION 4. FEES AND EXPENSES. The Calculation Agent shall be entitled to
such compensation for its services under this Agreement as may be agreed upon
with the Issuer, and the Issuer shall pay such compensation and shall reimburse
the Calculation Agent for all reasonable expenses, disbursements and advances
incurred or made by the Calculation Agent in connection with the services
rendered by it under this Agreement, including reasonable legal fees and
expenses, upon receiving an accounting therefor from the Calculation Agent.

     SECTION 5. RIGHTS AND LIABILITIES OF CALCULATION AGENT. The Calculation
Agent shall incur no liability for, or in respect of, any action taken, omitted
to be taken or suffered by it in reliance upon any Floating Rate Note,
certificate, affidavit, instruction, notice, request, direction, order,
statement or other paper, document or communication reasonably believed by it
to be genuine. Any certificate, affidavit, instruction, notice, request,
direction, order, statement or other communication from the Issuer made or
given by it and sent, delivered or directed to the Calculation Agent under,
pursuant to or as permitted by any provision of this Agreement shall be
sufficient for purposes of this Agreement if such communication is in writing
and signed by any officer of the Issuer. The Calculation Agent may consult
with counsel satisfactory to it and the opinion of such counsel shall
constitute full and complete authorization and protection of the Calculation
Agent with respect to any action taken, omitted to be taken or suffered by it
hereunder in good faith and in accordance with and in reliance upon the opinion
of such counsel. In acting under this Agreement, the Calculation Agent (in its
capacity as such) does not assume any obligation towards, or any relationship
of agency or trust for or with the holders of the Notes.

     SECTION 6. RIGHT OF CALCULATION AGENT TO OWN FLOATING RATE NOTES. The
Calculation Agent may act as Trustee under the Indenture and it and its
officers, employees and shareholders may become owners of, or acquire any
interests in, Floating Rate Notes, with the same rights as if the Calculation
Agent were not the Calculation Agent, and it may engage in, or have an interest
in, any financial or other transaction with the Issuer as if the Calculation
Agent were not the Calculation Agent.

     SECTION 7. DUTIES OF CALCULATION AGENT. The Calculation Agent shall be
obligated only to perform such duties as are specifically set forth herein and
no

2

 

other duties or obligations on the part of the Calculation Agent, in its
capacity as such, shall be implied by this Agreement.

     SECTION 8. TERMINATION, RESIGNATION OR REMOVAL OF CALCULATION AGENT. The
Calculation Agent may at any time terminate this Agreement by giving no less
than 90 days written notice to the Issuer unless the Issuer consents in writing
to a shorter time. Upon receipt of notice of termination by the Calculation
Agent. the Issuer agrees promptly to appoint a successor Calculation Agent.
The Issuer may terminate this Agreement at any time by giving written notice to
the Calculation Agent and specifying the date when the termination shall become
effective; provided, however, that no termination by the Calculation Agent or
by the Issuer shall become effective prior to the date of the appointment by
the Issuer, as provided in Section 9 hereof, of a successor Calculation Agent
and the acceptance of such appointment by such successor Calculation Agent. If
an instrument of acceptance by a successor Calculation Agent shall not have
been delivered to the Calculation Agent within 30 days after the giving of such
notice of resignation, the resigning Calculation Agent may petition any court
of competent jurisdiction for the appointment of a successor Calculation Agent.
Upon termination by either party pursuant to the provisions of this section,
the Calculation Agent shall be entitled to the payment of any compensation owed
to it by the Issuer hereunder and to the reimbursement of reasonable expenses,
disbursements and advances incurred or made by the Calculation Agent in
connection with the services rendered by it hereunder, as provided by Section 4
hereof.

     SECTION 9. APPOINTMENT OF SUCCESSOR CALCULATION AGENT. Any successor
Calculation Agent appointed by the Issuer or by a court following termination
of this Agreement pursuant to the provisions of Section 8 hereof shall execute
and deliver to the Calculation Agent and to the Issuer an instrument accepting
such appointment, and thereupon such successor Calculation Agent shall, without
any further act or instrument become vested with all the rights, immunities,
duties and obligations of the Calculation Agent, with like effect as if
originally named as Calculation Agent hereunder, and the resigning Calculation
Agent shall thereupon be obligated to transfer and deliver, and such successor
Calculation Agent shall be entitled to receive and accept, copies of any
available records maintained by the resigning Calculation Agent in connection
with the performance of its obligations hereunder.

     SECTION 10. INDEMNIFICATION. The Issuer shall indemnity and hold harmless
the Calculation Agent, its officers and employees from and against all actions,
claims, damages, liabilities, losses and expenses (including reasonable legal
fees and expenses) relating to or arising out of actions or omissions in any
capacity hereunder, except actions, claims, damages, liabilities, losses and
expenses relating to or arising from the negligence or willful misconduct of
the Calculation Agent, its officers or employees. The Calculation Agent shall
indemnify and hold harmless the Issuer, its officers and employees from and
against all actions, claims, damages, liabilities, losses and expenses
(including reasonable legal fees and expenses) relating to or arising from the
negligence or willful misconduct of the Calculation Agent, its officers or
employees. This Section 10 shall survive the payment in full of all
obligations under the Notes, whether by redemption, repayment or otherwise.

AGENT. Any corporation into which the Calculation Agent may be merged,

conversion or consolidation to which the Calculation Agent may be a party, or
any corporation to which the Calculation Agent may sell or otherwise transfer
all or substantially all of its corporate trust business, shall, to the extent
permitted by applicable law, become the Calculation Agent under this Agreement

                                   LIABILITIES

2.1      Sale and Purchase.

                  (a) At Closing, subject to the conditions hereof, Seller
         agrees to sell, assign, transfer, convey and deliver ("Transfer") to
         Buyer, and Buyer agrees to accept, purchase and pay for ("Purchase")
         the Assets. The Assets are subject to leases, easements, Permitted
         Encumbrances and other encumbrances specifically listed on the
         Schedules attached hereto. Some of the Assets are subject to rights of
         first refusal by third parties or necessity of obtaining consent from
         third parties for assignment, all as specifically listed in the
         Schedules attached hereto or in this Agreement.

                  (b) The Assets being Transferred by Seller to Buyer exclude
         the Third Party Inventory, described in Schedule 2.1.4(g), Third Party
         Property, described in Schedule 11.4(a), and the Excluded Assets,
         described in Schedules 2.1.1(f), and the Excluded Rail Cars, described
         in Schedule 2.1.2(f).

                  (c) Buyer acknowledges that Sinclair Marketing, Inc.
         ("Sinclair") has a right-of-first-refusal ("ROFR") to purchase Seller's
         interest in the two Terminals located at Boise and Burley, Idaho and
         that waiver of Sinclair's ROFR must be obtained before Seller can
         transfer its interest in the Terminals to Buyer. In the event that
         Sinclair refuses to provide the waiver in advance of Closing, the
         Terminals shall be removed from the Assets, and Seller shall enter into
         an equivalent, substitute arrangement/agreement with Buyer, on terms
         mutually acceptable to Buyer and Seller, subject to any required prior
         approval by applicable Antitrust Regulatory Authorities, such as a
         throughput agreement, lease agreement, license agreement or some other
         arrangement to provide to Buyer the same commercial benefit it would
         have acquired if it had purchased Seller's interest in the Terminals.
         The documents evidencing any substitute arrangement will include a full
         indemnity from Seller in favor of Buyer if such substitute arrangement
         is challenged by Sinclair or any other Person or otherwise fails to
         provide the required commercial benefit to Buyer.

                  (d) For Marketer Agreements, where the Marketer sells and
         delivers Motor Fuels to retail service stations located in states other
         than Utah, Wyoming, Idaho and Montana (as well as in these four
         states), Seller shall assign to Buyer Seller's interest in that portion
         of the Marketer Agreements, which covers the Marketers' sale and
         delivery of Motor Fuels to retail service stations located in the
         states of Utah, Wyoming, Idaho

                                       18
<PAGE>

         and/or Montana. Such assignment shall be in form and content mutually
         satisfactory to Buyer and Seller. Seller shall retain that portion of
         the Marketer Agreements that covers the Marketers' sale and delivery of
         Motor Fuels to retail service stations located in states other than
         Utah, Wyoming, Idaho and Montana.

                  (e) Three of the Retail Sites in Wyoming are branded
         "Coastal." Pursuant to the Trademark License Agreement between Seller
         and El Paso CGP Corporation (formerly known as The Coastal
         Corporation), Seller has the right to use the Coastal trademark at the
         three Retail Sites in Wyoming until April 24, 2011. If Buyer chooses to
         maintain the Coastal trademark at these three Retail Sites (until no
         later than April 24, 2011), Seller will assign to Buyer Seller's right
         to use the Coastal Trademark at these three sites until April 24, 2011.

                  (f) In addition to the Marketer Agreements, Seller is
         obligated to provide price incentives to certain Marketers, and Seller
         has entered into loan and reimbursement agreements, such price
         incentive, loan and reimbursement arrangements being listed in Schedule
         3.3(a)(iv). At Closing, Seller shall assign to Buyer and Buyer shall
         assume the obligations under these price incentive agreements, and
         Buyer shall receive a conveyance of and be entitled to receive
         reimbursement from Marketers of any unamortized balances of the loan
         and reimbursement agreements if Marketers breach these agreements or
         switch suppliers before the loans or reimbursement obligations are
         completely amortized.

2.2      Disclaimer of Warranties.

                  (a) Seller will Transfer the Assets to Buyer, and Buyer will

         to the Land and Improvements transferred by deed to Buyer (subject only
         to leases, easements and Permitted Encumbrances specifically noted on
         the Schedules) and to the personal property transferred by bill of sale
         or other instrument of assignment or conveyance to Buyer.

                  (b) SELLER EXPRESSLY DISCLAIMS ANY AND ALL LIABILITY FOR ANY
         IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR
         PURPOSE OF THE ASSETS. BUYER WAIVES THE UNIFORM COMMERCIAL CODE
         WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE WITH
         RESPECT TO SUCH IMPROVEMENTS AND EQUIPMENT, PROVIDED THIS WAIVER WILL
         NOT LIMIT THE REPRESENTATIONS AND WARRANTIES OF SELLER CONTAINED IN
         THIS AGREEMENT.

                  For and in consideration of the respective conveyances,

         cash deposit is provided, then Seller will invest such amount in

                  (c) At Closing, Buyer will pay to Seller $25 million plus the
         Net Inventory Estimate provided for in Section 3.3 less the Pension
         Benefit Amount Estimate reduced by the sum of the cash Deposit amount
         and any accrued interest on such cash Deposit.

                  (h) Credit Card Proceeds. Seller sells product to Marketers in
         Utah, Wyoming, Idaho and Montana on certain credit terms. When the
         Marketers resell the product to their customers, the Marketers submit

         when Seller's assignment to Buyer of Seller's supply agreements with
         the Marketers in Utah, Wyoming, Idaho and Montana becomes effective,
         many of these Marketers will owe Seller for product purchased from
         Seller prior to the Effective Time. This amount due Seller shall be
         part of Seller's accounts receivable. For up to thirty (30) days beyond
         the Closing Date, Seller shall have the right to retain credit card
         proceeds arising with respect to sales transactions executed prior to
         the Effective Time from any Marketers in Utah, Wyoming, Idaho and

         sold by Seller to the Marketers prior to the Effective Time. After
         Seller has been paid all amounts owing to it for the pre-Effective Time
         accounts receivable, the remaining credit card proceeds will be
         transferred to and become the property of Buyer.

         towards obtaining the Antitrust Regulatory Authorities approval of
         Seller's sale of the Assets to Buyer pursuant to the terms and

<PAGE>

         are held separately and managed separately and independently from
         Seller and Seller's other assets and business operations, from
         September 10, 2002 until Closing (the "Held Separate Period"). During
         the Held Separate Period, the Assets and the Operations will be under
         the management of the trustee approved by the FTC ("Held Separate
         Trustee") and the manager approved by the Federal Trade Commission
         ("Held Separate Manager"), and Seller's employees employed at the
         Assets during this period will be "Held Separate Employees", who will
         report to the Held Separate Manager. During the Held Separate Period,
         Seller and Buyer will need to coordinate and cooperate with the Held
         Separate Manager and Held Separate Employees with respect to certain
         matters involving the Assets including gaining access to and inspecting
         the Assets and Operations, interviewing Held Separate Employees and
         conducting inventories of the Assets.

                  (c) Seller and Buyer agree to use all reasonable efforts to
         obtain the approval of the Antitrust Regulatory Authorities to the
         transactions contemplated by this Agreement. In this connection, Seller
         will (i), as promptly as practicable after execution of this Agreement,
         file with the applicable Antitrust and Regulatory Authorities all
         reports and other documents required to be filed with such agencies
         concerning the transactions contemplated hereby (ii) will promptly
         comply with, or cause to be complied with, any requests by the
         Antitrust Regulatory Authorities for additional information concerning
         such transactions in each case so that approvals can be granted as soon
         as practicable after the execution of this Agreement and (iii) take all
         actions reasonably necessary and within Seller's control to obtain the
         required approvals from Antitrust Regulatory Authorities as soon as
         practicable following the execution of this Agreement.

                  (b) the regular, full-time and regular, part-time employees,
         including Short-Term Inactive Employees as defined below in paragraph
         4.1(c), working at the Refinery, in marketing support and at the Retail

         Non-Represented Employees, the "Employees"); and

                  (c) the employees at the Refinery and in marketing support
         who, as of the date of this Agreement, are not actively at work,
         including those who are on inactive employee status or leave of absence

         illness but who is not on inactive employee status or leave of absence
         other than a Family Medical Leave. "Long-Term Inactive Employee" shall
         mean an employee who is on inactive employee status or leave of absence
         except a Family Medical Leave. Schedule 4.1 shall identify in separate
         groupings the Short-Term Inactive Employees who are on Family Medical
         Leave and all the Long-Term Inactive Employees, and the reason for such

         again at Closing.

4.2      Represented Employees.

                  Seller represents that it is bound by the Collective
Bargaining Agreement, which is attached in Schedule 4.2(a)(i) ("Collective
Bargaining Agreement") between Seller and the Paper, Allied-Industrial Chemical
and Energy Workers International Union - Local 8-578 (the "Union"). Buyer agrees
to recognize the Union as the exclusive representative for the employees in the
bargaining unit covered by the Collective Bargaining Agreement. Subject to any
limitations imposed by Applicable Law, Buyer shall adopt the Collective
Bargaining Agreement and maintain it in full force and effect during its current
term, except for changes permitted under the Collective Bargaining Agreement or
mutually agreed to between the Buyer and the Union and except that Buyer shall
not be required to continue the existing employee benefits (as set out on
Schedule 4.2(b) ("Seller's Union Benefits"), but shall be entitled to establish
such benefits as may be allowed by the Collective Bargaining Agreement ("Buyer's
Union Benefits") for employees covered by the Collective Bargaining Agreement,
and such employees shall be entitled to participate in Buyer's Union Benefits.
Buyer shall make every commercially reasonable effort to obtain the approval of
all third party plan providers for participation in such plans by said
Employees.

4.3      Offers of Employment.

                  (a) Offers of Employment by Buyer.

                           (i) Buyer shall offer regular, full-time or regular,
                  part-time employment to all Represented Employees (excluding
                  Long-Term Inactive Employees but including Short-Term Inactive
                  Employees) on the terms provided

                                       35
<PAGE>

                  in the Collective Bargaining Agreement, except to the extent
                  otherwise permitted under Section 4.2; and

                           (ii) Except as otherwise agreed between Buyer and
                  Seller, Buyer shall offer regular, full-time or regular,
                  part-time employment to the Non-Represented Employees
                  (excluding Long-term Inactive Employees but including
                  Short-Term Inactive Employees). Seller shall make every
                  reasonable effort, prior to the Effective Time, to retain in
                  employment all Employees.

                           (iii) Buyer shall offer employment to Non-Represented
                  Employees at a monthly salary or hourly rate of pay ("Base Pay
                  Rate") that is at least equivalent to the Base Pay Rate that
                  the Employee had with the Seller as of the last regularly
                  scheduled workday immediately prior to the Effective Time.
                  Buyer shall establish a bonus plan for Non-Represented
                  Employees that is substantially comparable to the bonus plans
                  in place for such Non-Represented Employees prior to the
                  Effective Time. Buyer shall provide, for a period of one year
                  following the Effective Time, to the Non-Represented
                  Employees, which become employed by Buyer as of the Effective
                  Time and only to the extent such employees continue to be
                  employed by Buyer, benefits that are reasonably and
                  substantially comparable in the aggregate to the benefits
                  provided to the Non-Represented Employees by Seller
                  immediately prior to the Effective Time.

                  (b) Employment Data. Seller shall, at least ten (10) days
         prior to Closing, provide Buyer with employment data, including, but
         not limited to, the name, title, employment history (including years of
         service), and current salary, bonus and incentive opportunity, accrued
         and used vacation, sick or short-term disability pay accrued and

                                       36
<PAGE>

         used, exempt or non-exempt status, and the job grade of each
         Represented and Non-Represented Employee. Seller shall retain
         responsibility and liability, if any, for all Long-Term Inactive
         Employees.

                  (c) Notice of Offers. Buyer shall notify Seller of the
         acceptance of any employment offer made by Buyer to the Employees,
         within five (5) business days of the acceptance of such offer.

                  (d) Orderly Transition. Buyer shall employ each Employee who
         accepts Buyer's offer of employment. Seller agrees to use its
         reasonable efforts to assist Buyer in the orderly transition to Buyer
         of any such Employees. Each such accepting Employee shall, from the
         Effective Time, be referred to in this Agreement as an "Acquired
         Employee".

                    (e) Employment Assurances. For a period of one year
         following the Effective Time, Buyer shall not reduce the Acquired
         Employee's Base Pay Rate, the type of benefits available to the
         Acquired Employees, the dollar amount of the Buyer's contribution to
         such benefits, the dollar amount of benefits available under such
         benefits or any other rights of the Acquired Employees under such
         benefits, and shall not terminate such Acquired Employee's employment
         except for "cause". For the purposes of this section, "cause" shall
         include (i) any meaning ascribed to "cause" under any Applicable Law,
         (ii) the commission of an illegal or unethical act, (iii) negligence or
         willful misconduct in carrying out (or failing to carry out) the
         employee's duties or responsibilities, (iv) any other failure to comply
         with any of Buyer's policies or practices that could have resulted in
         termination of such employee, and (v) any other concept of cause which
         could result in termination under Seller's general practices. At the
         Effective

                                       37
<PAGE>

         Time and during the stated one year period, Acquired Employees shall be
         treated no less favorably than similarly situated employees of Buyer.

                  (f) Seller waives any claims it may have under any employment,
         confidentiality, non-disclosure, trade secret or non-competition
         agreement, or similar agreement, to the extent that they would
         otherwise limit any Acquired Employees in the performance of their
         duties for Buyer.

                  (g) Seller plans to provide a merit increase to its
         Non-Represented Employees' Base Pay Rates effective March 1, 2003 as
         more particularly described in Schedule 4.3(g) (the "Merit Increase").
         If the Effective Time occurs before March 1, 2003, Buyer shall,
         effective on March 1, 2003, provide to the Acquired Employees the
         equivalent Merit Increase to the Base Pay Rate, which the Acquired
         Employees would have received from Seller if they were still employed
         by Seller on March 1, 2003.

4.4      Employee Benefits for Acquired Employees.

                  (a) For a period of at least one year following the Effective
         Time, Buyer shall permit the Non-Represented Employees, who become
         Acquired Employees, to participate in Buyer's employee pension benefit
         plans, as that term is defined by Section 3(2) of the Employee
         Retirement Income Security Act of 1974 as amended ("ERISA"), employee
         welfare benefit plans (as that term is defined by Section 3(1) of
         ERISA), and other benefit and compensation programs, policies, and
         practices, that are or will be generally available to Buyer's similarly
         situated salaried employees. Buyer shall provide each Non-Represented
         Employee with the benefits that are set out on Schedule 4.4 ("Salaried
         Employee Benefits") on terms as are currently applicable to similarly
         situated salaried employees, consistent with the Employment Assurances
         in Section 4.3(e).

                                       38
<PAGE>

                  (b) Buyer shall permit the Represented Employees to
         participate in Buyer's benefit plans per Article VII of the Collective
         Bargaining Agreement. Buyer shall permit the Represented Employees who
         become Acquired Employees to participate in compensation programs,
         policies and practices as per the Collective Bargaining Agreement.

4.5      Welfare Plan Coverage.

                  (a) With respect to each Acquired Employee who elects to
         participate in Buyer's employee welfare benefit plans, Buyer shall, to
         the extent allowed under Buyer's plans, waive any pre-existing
         condition exclusions to coverage, any evidence of insurability
         provisions, any active at work requirement and any waiting period or
         service requirements under its employee welfare benefit plans that did
         not exist or had been waived or otherwise satisfied under comparable
         employee welfare benefit plans sponsored by the Seller, provided the
         Acquired Employee enrolls within thirty-one (31) days of the Closing
         Date. For each Acquired Employee, Buyer shall also apply towards any
         deductible requirements and out-of-pocket maximum limits under its
         employee welfare benefit plans applicable to the year of such Acquired
         Employee's employment commencement date, any amounts paid by such
         Acquired Employee toward such requirements and limits under the
         Seller's employee welfare benefit plans in which he or she participated
         during such year. Seller will secure information as has been received
         by the welfare claims processors as of the last day of the calendar
         month in which the Effective Time occurs, from others and/or provide
         the information necessary within 14 days after the end of the calendar
         month following the calendar month in which the Effective Time occurs
         to establish any such amounts paid by Acquired Employees. After

                                       39
<PAGE>

         the initial enrollment of Acquired Employees into Buyer's health plans,
         and thereafter upon written request of Seller (which request shall be
         no more frequently than quarterly) until eighteen (18) months after the
         Closing Date, Buyer shall furnish Seller with the names of the Acquired
         Employees who enroll in any of Buyer's health plans and specify the
         health plans in which such Acquired Employees enroll.

                  (b) Buyer shall, to the extent permitted under Buyer's plans,
         cause all those employee welfare benefit plans, programs, policies, and
         practices in which the Acquired Employees participate, including but
         not limited to, Buyer's vacation, severance pay plan (for any Acquired
         Employees who did not receive benefits under the Workforce
         Stabilization Plan), disability and sick leave programs, to recognize
         past service as recognized by the Seller's employee welfare benefit
         plans (such past service as reflected in the personnel records
         furnished to Buyer by Seller) for purposes of eligibility to
         participate, eligibility for enrollment, eligibility for the
         commencement of benefits, and eligibility for the levels of benefits
         where there are service-related benefit schedules.

                  (c) If Buyer establishes a flexible spending plan (the
         "Buyer's FSP") Acquired Employees shall be eligible to participate in
         Buyer's FSP following the Closing Date. As appropriate, Seller and the
         Buyer shall take all reasonable steps necessary or appropriate so that
         the account balances under the Seller's Flexible Spending Plan (the
         "Seller's FSP") of each Acquired Employee who has elected to
         participate therein in the year in which the Closing Date occurs shall
         be transferred, as soon as practicable after the Closing Date, from the
         Seller's FSP to the Buyer's FSP, and so that the contribution elections
         of each such Acquired Employee as in effect immediately before the
         Closing Date remain in effect under the Buyer's FSP immediately after
         the transfer of such

                                       40
<PAGE>

         account balance. If the aggregate amount of the transferred account
         balances of the Acquired Employees is negative, then the Buyer shall
         pay Seller the amount of such aggregate negative balance to the extent
         recouped by the Buyer. From and after the date an Acquired Employee's
         account in Seller's FSP is transferred in accordance with this Section
         4.5, the Buyer shall be solely responsible for, and shall satisfy from
         the Buyer's FSP, all claims, whether incurred before, on or after the
         Closing Date, for which such Acquired Employee was entitled to seek
         reimbursement under the Seller's FSP for the year in which the Closing
         Date occurs.

4.6      Pension.

                  (a) Buyer shall cause its employee pension benefit plans
         (whether defined contribution plans, as defined in Section 3(34) of
         ERISA, or defined benefit plans, as defined in Section 3(35) of ERISA)
         to recognize the past service of the Acquired Employees as recognized
         by the Seller's employee pension benefit plans for purposes of
         eligibility to participate, eligibility for enrollment, eligibility for
         vesting, eligibility for the commencement of benefits, eligibility for
         the forms of benefits, eligibility for early retirement subsidies and
         eligibility for the levels of benefits where contributions to the plan
         or payments from the plan depend in whole or in part on service. Buyer
         shall cause its employee pension benefit plans to recognize service
         recognized by the Seller's employee pension benefit plans for purposes
         of benefit accruals.

                  (b) If the Buyer has an employee pension defined benefit plan
         (as defined in Section 3(35) of ERISA), the Buyer may provide that the
         Acquired Employee's accrued benefit in the Buyer's employee pension
         plan, which would be payable at normal retirement age in straight life
         annuity form (regardless of actual form of payment) will be

                                       41
<PAGE>

         reduced by the accrued benefit payable at normal retirement age in
         straight life annuity form in the Seller's employee pension defined
         benefit plan (regardless of actual payment date or form). As soon as
         practicable after the Effective Date, Seller will provide to Buyer a
         list of the Acquired Employees' accrued benefits payable at normal
         retirement age in straight life annuity form and lump sum form from
         Seller's employee pension defined benefit plan.

                  (c) If the Buyer does not have an employee pension defined
         benefit plan (as defined in Section 3(35) of ERISA), the Parties shall
         negotiate and provide an appropriate provision such as would provide
         the Acquired Employees with benefits that are reasonably and
         substantially comparable in the AGGREGATE.

4.7      Defined Contribution Plan

                  If administratively feasible, and allowed pursuant to Buyer's
defined contribution plan, Buyer agrees to accept as a direct rollover each
Acquired Employee's distribution from Seller's savings plans for any Acquired
Employee who so elects, for at least seven months after Closing. Acquired
Employees will also have the option to leave their accounts in Seller's savings
plan(s) (except in the case of certain small accounts) or to request
distribution of those portions of the accounts that are currently distributable,
under the terms of the plan(s). Buyer will have no obligation with respect to
amounts attributable to Seller's savings plan other than acceptance of the
direct rollovers requested by Acquired Employees. Seller and Buyer agree to
cooperate to ensure a smooth transition/rollover of the account balances from
the Seller's defined contribution plan to the Buyer's defined contribution plan.
Buyer shall provide Seller with a copy of the most recent favorable
determination letter from the Internal Revenue Service with respect to the plan
of Buyer which will be receiving a direct rollover.

                                       42
<PAGE>

4.8      Vacation.

                  (a) Seller shall compensate Acquired Employees for vacation
         the Acquired Employees have carried over from prior years with Seller
         up to through and including the Effective Time.

                  (b) Buyer shall honor the Acquired Employee's remaining
         accrued vacation entitlement in and for the calendar year 2003, but not
         any carry over amounts which shall be the responsibility of Seller. At
         the beginning of the calendar year next succeeding the Closing Date
         (i.e., calendar 2004), employees would be covered by the Buyer's
         vacation schedule with recognition of past service to determine
         vacation entitlement level. Within 30 days after the Effective Date,
         Seller will provide to Buyer a list of the remaining accrued vacation
         entitlement for the Acquired Employees.

                  (c) Within 30 days after the Closing Date, year 2003 earned
         and accrued vacation liabilities of Acquired Employees will be
         calculated as follows: the days during 2003 that Seller owned the
         Assets will be calculated as will the number of days Buyer will own the
         Assets. Fractions will be calculated in which the numerators will be
         the number of days during 2003 that Seller owned the Assets and the
         number of days during 2003 that Buyer will own the Assets,
         respectively, and the denominators will be the number of days in year
         2003. These fractions will be multiplied by the number of remaining
         eligibility hours of vacation entitlement (not including carried over
         vacation) for Acquired Employees at the Effective Time, whether already
         taken or not. This procedure will be applied separately to hourly and
         salaried Acquired Employee vacations. The resulting calculation will
         yield the number of hours of vacation attributable to the account of
         both the Buyer and the Seller. Actual remaining hours of vacation
         entitlement (not including carried over vacation) will be calculated
         separately for salaried and hourly Acquired Employees. To the extent
         the total actual remaining vacation entitlement

                                       43
<PAGE>

         (not including carried over vacation hours) to be taken in 2003 by
         Acquired Employees is greater than the total number of vacation hours
         attributable to the Buyer, Seller will pay Buyer the dollar amount of
         the difference. This dollar amount will be calculated by multiplying
         the total number of vacation hours (by which the total actual remaining
         vacation entitlement less carried over vacation hours to be taken in
         2003 exceeds the total number of vacation hours attributable to Buyer
         in 2003) by the average hourly rate (based on a group rate and not an
         individual-by-individual rate analysis) or the average staff employee
         rate (based on a group rate and not an individual-by-individual rate
         analysis). Seller will then pay the resulting dollar amount to Buyer
         within thirty (30) days after the Closing Date.

4.9      Liabilities and Indemnities.

                  (a) Workers' Compensation. Seller shall be responsible for
         workers' compensation claims with respect to any Acquired Employee if
         the incident or alleged incident giving rise to the claim occurred at
         or prior to the Effective Time. Buyer shall be responsible for any
         workers' compensation claims with respect to any Acquired Employee if
         the incident or alleged incident giving rise to the claim occurs after
         the Effective Time. In the event of doubt as to the date of the
         occurrence of the incident or alleged incident, Buyer shall process the
         claim. With respect to all workers' compensation or similar claims
         (hereinafter "Compensation Claims") filed with an appropriate agency by
         or on behalf of any Acquired Employee employed by Seller immediately
         prior to the Effective Time and thereafter employed by Buyer (such

                                       44
<PAGE>

         employees are, for purposes of this paragraph, hereinafter collectively
         referred to as "Claiming Employee"), or by the spouse, dependent(s) or
         personal representative of such Claiming Employee which is first filed
         after the Effective Time, (A) Seller shall process, defend and be
         responsible for, and shall indemnify Buyer and its Affiliates against
         any such Compensation Claim if the incident or alleged incident giving
         rise to the claim is alleged to have occurred on or prior to the
         Effective Time, (B) Buyer shall process, defend and be responsible for,
         and shall indemnify Seller against any such Compensation Claim if the
         incident or alleged incident giving rise to the claim is alleged to
         have occurred subsequent to the Effective Time, and (C) in the event
         any such Compensation Claim is filed after the Effective Time and the
         incident or alleged incident giving rise to the claim is alleged to
         have occurred both prior and subsequent to the Effective Time, Buyer
         shall, in consultation with Seller and taking into account Seller's
         reasonable suggestions, process such claim (and Seller shall reimburse
         Buyer for its allocable portion of the reasonable cost of defense), and
         the liability for such claim as between the parties shall be based upon
         the length of exposure to such incident or alleged incident while
         employed by Seller and then by Buyer. Thus, as between the parties, the
         proportionate share of liability shall equal a fraction the denominator
         of which shall be the Claiming Employee's total length of exposure to
         such incident or alleged incident, and the numerator of which shall be
         in the case of Buyer, the Claiming Employee's total length of exposure
         while employed by Buyer, and in the case of Seller, the Claiming
         Employee's total length of exposure while employed by the Seller.

                  (b) Indemnities.

                           (i) To the maximum extent permitted by Applicable
                  Law, Seller shall defend, indemnify, and hold harmless Buyer
                  and its Affiliates from and against any Damages, and any
                  fines, penalties and assessments, arising out of (a) claims by
                  Employees (other than Acquired Employees) that arise prior to,
                  on, or after the Effective Time and relate to their employment
                  with, or the termination of their employment from, the Seller
                  or its Affiliates; and (b) claims by Acquired Employees that
                  arise on or prior to the Effective Time which relate to their
                  employment with, or the termination of their employment from,
                  the Seller or its Affiliates; and

                           (ii) To the maximum extent permitted by Applicable
                  Law, Buyer shall defend, indemnify, and hold harmless Seller
                  and its Affiliates from and against any Damages, and any
                  fines, penalties and assessments, arising out of claims by the
                  Acquired Employees that arise after the Effective Time and
                  relate to their employment with, or the termination of their
                  employment from, the Buyer.

4.10     Transition of Employees.

                  From and after the Closing Date, Buyer and Seller agree to
cooperate to ensure an orderly transition and subsequent administration of the
Acquired Employees. Upon reasonable notice a Party will provide, or cause to be
provided, such information and assistance to the other Party as may reasonably
be requested by that Party in connection with any employment-related litigation,
claim, grievance, arbitration, discovery, or other proceeding with respect to
Employees or Acquired Employees, to which Buyer or Seller or any of their
Affiliates is or may become a party.

4.11     Pension Benefit Amount.

                  (a) Calculation. As soon as practicable after Closing, but in
         no event later than ninety (90) days after Closing, Seller will provide
         to Buyer a schedule which reflects the final accrued benefits payable
         at normal retirement age in straight life annuity form for each
         Acquired Employee. As soon as practicable after receipt of this final
         benefit information, Buyer and Seller shall, with the assistance of
         their respective actuaries, determine the amount of the difference
         between the projected benefit obligation and the accumulated benefit
         obligation of the Seller's pension plan obligation with respect to the
         final accrued benefits of the Acquired Employees (the "Pension Benefit
         Amount"). The Pension Benefit Amount will be determined applying the
         actuarial assumptions as set forth in Schedule 4.11 attached hereto.

                  (b) Cost of Actuaries. Each Party shall bear the cost of its
         designated actuary in calculating the final Pension Benefit Amount.

                  (c) Pension Benefit Adjustment. Seller and Buyer agree to
         adjust the Purchase Price by making a Pension Benefit Adjustment as
         follows:

                           (1) If the final Pension Benefit Amount as determined
                  pursuant to subsection (a) above exceeds the Pension Benefit
                  Estimate, then Seller shall make a payment in the amount of
                  such difference to Buyer; and

                           (2) If the final Pension Benefit Amount as determined
                  pursuant to subsection (a) above is less than the Pension
                  Benefit Estimate then Buyer shall make a payment in the amount
                  of such difference to Seller; and

                           (3) Each payment required under this Section 4.11(c)
                  shall be made by wire transfer of funds to an account
                  specified by the receiving party within five

                                       47
<PAGE>

                  (5) days following calculation of the final Pension Benefit
                  Amount and the Pension Benefit Adjustment. Any amount not paid
                  when due shall bear interest at the Late Payment Rate for the
                  period past due.

                           (4) All payments made pursuant to this subsection
                  4.11(c) will be treated as an adjustment in the Purchase
                  Price.

                                    ARTICLE 5

agency having jurisdiction thereof nor are there any current union
representation claims involving any of the Employees. Seller does not have
Knowledge of any strike, work stoppages, work slowdowns, picketing, lockouts or
similar labor activity or of any threats thereof, except for routine grievance
matters, by or with respect to any of the Employees. And, except as set forth in
Schedule 5.14, to the Knowledge of Seller, there exits no charge of
discrimination or lawsuit involving any alleged violation of any fair employment
law, wage payment law, occupational safety and health law, and no threatened or
pending litigation arising out of any employment relationship or other

         of any third party (and Seller is not aware of any assertions made by
         any third party alleging such infringement), (ii) Seller's rights in

         to license the right to use, all such patented technology to Buyer in

         technology to Buyer), and (iv) no third party has rights in, or
         otherwise has the right to restrict the Buyer's use of the patented
         technology as of and following the Closing (except for the exclusive

         complete list of all Licensed Technology, which is used or held for use
         in the operation of the Assets, owned by a third party and licensed or

         may be, has the right to use such Licensed Technology as it is
         currently being used in connection with the Assets, and such licenses
         are valid, binding, in full force and effect and enforceable against
         such third party licensor or sublicensor in accordance with their
         terms. Except for the Licensed Technology disclosed on Schedule
         16.1(c), such Licensed Technology may be assigned or sublicensed to
         Buyer without the consent of any third party.

                  (c) To Seller's Knowledge, no product, component, method,
         process, or material (including computer software) used in Operations
         infringes on, misappropriates, or otherwise violates the Intellectual
         Property rights of any third party.

                  (d) There are no demands, actions or proceedings pending or to
         Seller's Knowledge threatened, against Seller relating to the
         Operations alleging infringement, misappropriation, or violation of any
         Intellectual Property right of any Person, and Seller has no Knowledge
         that the Operations infringe, misappropriate, or violate the
         Intellectual Property rights of any Person. To Seller's Knowledge, no
         Person is infringing, misappropriating, challenging or violating, the
         Intellectual Property owned or used or held for use by Seller in
         connection with the Operations.

5.16     Maintenance of Assets.

                  Seller will continue to perform until Closing, maintenance on
the Assets in accordance with its normal practices for all of its United States
refineries, pipelines, retail sites and equipment comparable to the Assets based
upon the use which has been and will be made of

                                       56
<PAGE>

the Assets prior to Closing. Seller's normal maintenance practices are to
maintain adequately the Assets consistent with good order and repair and in a
reasonably safe condition.

5.17     Shared Assets.

                  Schedule 5.17 lists all assets located at the Refinery that
are shared with other operations, facilities or Affiliates of Seller that will
not be included in the Assets transferred to Buyer at Closing.

5.18     Financial Statements.

                  The unaudited financial statements with respect to the Assets
and the Operations attached as Schedule 5.18 have been delivered by Seller to
Buyer. Such financial statements are hereinafter referred to as the "Financial
Statements". The Financial Statements, including the related notes and
schedules, have been prepared from the books and records of Seller relating to
the Assets and Operations in conformity with United States generally accepted
accounting principles applied on a basis consistent with preceding years and
throughout the periods involved and present fairly the financial position and
results of operations of the Operations as of the dates of such statements.

5.19     Instruments in Full Force and Effect.

                  The contracts and agreements constituting a part of the Assets
including the Contracts, Leases and Easements, Marketer Agreements, Permits and
Pipeline Agreements ("Instruments") are valid, binding and in full force and
effect, have not been amended or supplemented in any manner or respect except as
disclosed on Schedule 5.19, and upon assignment and assumption, with applicable
consents if necessary, will be enforceable by Buyer in accordance with their
respective terms. There are no defaults by Seller thereunder and Seller knows of
no defaults thereunder by any other party thereto, and no event has occurred
that with

                                       57
<PAGE>

the lapse of time or action or inaction by any party thereto would result in a
violation thereof or a default thereunder. Subject to any required third party
consents, none of the rights under the Instruments will be impaired by the
consummation of the transactions contemplated by this Agreement, and all such
rights will inure to and be enforceable by Buyer after the Closing without the
authorization, consent, approval, permit or licenses of or filing with any other
Person. The Instruments constitute all material contracts and agreements used in
or relating to the Operations other than the contracts and agreements
specifically listed as Excluded Assets.

5.20     Shipping History.

                  The Assets assigned to Buyer at the Closing will include all
of Seller's and its Affiliates' rights to the shipping history of Seller and its
Affiliates for feedstocks into the Refinery and products out of the Refinery,
including shipping history on the Chevron crude and products pipeline and the
Pacific pipeline. In addition, Seller will use best efforts to obtain for Buyer
the shipping history on the Chevron crude and products pipeline and the Pacific
pipeline which has been used by others to supply the Assets or furnish offtake
from the Assets. Schedule 5.20 includes a description of Seller's pipeline
history and allocation of pipeline capacity with respect to the Refinery and
other Assets and Operations. Absent such assignment, Seller shall enter into an
equivalent, substitute arrangement/agreement with Buyer, on terms mutually
acceptable to Buyer, to provide Buyer with the same commercial benefit of such
assignment of capacity.

5.21     Sufficiency of the Assets.

                  Except for the Excluded Assets, the Assets being transferred
to Buyer by Seller at Closing include all properties, assets and rights used by
or held for use by the Seller in the Operations. Seller further represents that
(i) the Assets in use at the Refinery from August 2,

                                       58
<PAGE>

2002 through the Effective Time include, in all material respects, the same
assets, rights and properties used in the operation of the Refinery during the
period from January 1, 2002 through August 2, 2002 and (ii) since August 2,
2002, the Assets have been operated by Seller in the ordinary course of business
and Seller has not removed or retired any material assets or relinquished any
material rights used or held for use in the Refinery.

5.22     Employee Benefit Matters.

                  Buyer, from and after the Effective Time, will not have any
liability under or with respect to any of Seller's or its Affiliates "employee
plans" as such term is defined in Section 3(3) of ERISA or any other
compensation plan or arrangement prior or heretofore maintained by Seller or its
Affiliates.

5.23     Absence of Certain Business Practices.

                  Neither Seller nor any officer, employee or agent of Seller,
nor any other Person acting on its behalf, has, directly or indirectly, given or
agreed to give any gift or similar benefit to any customer, supplier, government
employee or other Person who is or may be in a position to help or hinder the
operation of the Assets (or to assist Seller in connection with any actual or
proposed transaction) which (1) might subject Seller to any damage or penalty in
any civil, criminal or governmental litigation or proceeding, (2) if not given
in the past, might have had a material adverse effect on the Assets or its
operation of the Assets, or (3) if not continued in the future, might materially
adversely effect the Assets.

the commercial potential, condition and usefulness of the Assets, taking into
consideration all current Legal Requirements and the likelihood that such laws

including the making of employees available to Seller at Seller's expense as
witnesses or deponents as Seller may request for (a) financial reporting, (b)
tax or similar purposes or (c) purposes of investigating claims, or conducting
litigation or administrative proceedings with third parties or government
agencies. Buyer will keep and maintain the records to which Seller or its
representatives may request access pursuant to this Section 11.1, such records
to be maintained for a period of ten (10) years from the Closing Date in the
case of environmental records and five (5) years for all other records or such
longer period as may be required by law or reasonably requested by Seller;
provided, if Buyer decides to dispose of or destroy such records prior to such
time periods it may do so provided it provides at least thirty (30) days notice
to Seller prior to such disposal or destruction and provides Seller with an
opportunity to take possession of such records.

11.2     Qualifications, Approvals, Licenses and Permits.

                  Buyer shall proceed diligently and in good faith and shall use
reasonable efforts at Buyer's expense to obtain all necessary United States and

and after the Effective Time.

11.3     No Trademarks

                  Except as specifically permitted under Article 16 and the

Trademarks is granted by this

Agreement or by the transfer of the Assets to Buyer. Buyer acknowledges and
agrees that Seller and its Affiliates have the absolute and exclusive right to
the Trademarks (and signs, which identify or portray Seller's Trademarks), and
all rights to which, and the goodwill represented thereby and pertaining
thereto, are being retained by Seller and its Affiliates, subject however to
rights under the Trademark License Agreement. Consistent with the terms and
conditions of the Trademark License Agreement, Buyer shall be allowed to use
signage, which identifies or portrays such Trademarks and brand names of Seller.
Seller shall continue to retain ownership of these signs, which shall be loaned
to Buyer. Seller acknowledges that its right to signs cover only the proprietary
"facia" signage which actually includes or incorporates the proprietary
trademark or logo of Seller.

11.4     Third Party Property.

                  Buyer shall grant or continue to grant such rights-of-way,
easements or other rights of ingress or egress necessary to allow (a) any third
party which holds any Third Party Property, described in Schedule 11.4(a), on
the Land to have access to such Third Party Property for the purposes of
repairing, maintaining or otherwise utilizing such property, for so long as the
Third Party Property remains on the Land; and (b) Seller or its Affiliates which
hold any assets described on Schedule 11.4(b) to have access to such assets for
the purposes of operating, repairing, maintaining or otherwise utilizing such
assets.

                          COVENANTS OF BUYER AND SELLER

                  Buyer and Seller each covenant as follows:

12.1     Antitrust Compliance.

                  Notwithstanding any other provision of this Agreement, either
Party at any time may terminate this Agreement upon notice to the other, without
liability to the other Party, if the Antitrust Regulatory Authorities advise
Seller of their final disapproval (by the vote of the Commissioners) of the
transactions contemplated by this Agreement.

12.2     Purchase Price Allocations.

                  Schedule 12.2 is an allocation of the Purchase Price (the
"Allocation") among the Assets pursuant to the provisions of Section 1060 of the
Code and the Treasury Regulations promulgated thereunder. Any subsequent
adjustments to Purchase Price shall be reflected in Schedule 12.2, as revised by
Buyer, in a manner consistent with the Allocation and Section 1060 of the Code
and the Treasury Regulations promulgated thereunder. The parties recognize that
the Purchase Price does not include the Buyer's acquisition expenses and that
Buyer will allocate such expenses appropriately. Buyer and Seller shall not take
any position on their respective income tax returns that is inconsistent with
the allocation of the Purchase Price as set forth in Schedule 12.2. Buyer and
Seller shall duly prepare and timely file Internal Revenue Service Form 8594 and
Form 8824 and any comparable state, local or foreign forms (including any
successor forms) (collectively the "1060 Forms") and any required attachments
thereto required under Section 1060 of the Code, the Treasury Regulations
promulgated thereunder or any provisions of state, local, or foreign law in
accordance with the Allocation among the Assets as set forth in such Schedule
12.2. The Parties shall cooperate in the preparation of any 1060 Forms and shall
file such 1060 Forms in the manner required by applicable law.

                                       73

12.3     Tax Election.

                  Either Party may elect to structure the conveyance, transfer
and/or assignment of all or an applicable portion of the Assets as a tax-free
exchange pursuant to Section 1031 of the Code (a "1031 Exchange"), provided that
such Party gives notice of such election to the other Party at least fifteen
(15) days prior to the Effective Time, and provided that Seller or Buyer shall
not be required to take title to any other property. If such an exchange is
elected by such Party (the "Electing Party"), the Parties will execute all
necessary 1031 Exchange documents (provided, that any costs and expenses
incurred shall be borne by the Electing Party), which shall be in a form
mutually acceptable to the Parties. The Electing Party will indemnify the other
Party and its Affiliates, employees and agents against any and all Damages,
which may be sustained by them on account of or in connection with such election
to structure the transaction as a 1031 Exchange.

12.4     Collection of Amounts Owed to a Party.

                  It is the intention of the Parties that, as between the
Parties, Seller shall be entitled to all income attributable to the operations
conducted prior to and including the Effective Time and Buyer shall be entitled
to all income attributable to the operations conducted after the Effective Time.
Each Party shall pay to the other Party, promptly after receipt thereof, any
amount received by said Party from any third party with respect to (i) rentals,
fees or other revenues relating to the operation of the Assets and attributable
to the ownership period of the other Party; and (ii) products delivered,
services performed or other obligations performed by the other Party and
attributable to the ownership period of such other Party.

<PAGE>

12.5     Payment of Transfer Taxes; Recording Fees.

                  Buyer and Seller shall each pay one-half of all transfer
Taxes, which are assessed or imposed on the transfer of the Assets from Seller
to Buyer. By way of example, but not exclusion, Buyer and Seller shall share the
costs equally of all real estate transfer taxes, or other excise taxes on real
estate sales, all sales taxes, business occupation taxes, applicable motor fuel
taxes and applicable environmental taxes and fees on all petroleum products
transferred, as well as any other Taxes assessed or imposed on the transfer or
sale of the assets, personal property or inventory included herein, and all
costs to record any deeds. Each Party shall cooperate with the other to take
advantage of all applicable tax exemptions and provide applicable tax exemption
certificates. Buyer and Seller shall each pay one-half of any title insurance
premium due for any title insurance policies obtained by or for Buyer and
one-half of the costs of any required surveys.

12.6     Payment of Certain Expenses Due and Payable After the Effective Time;
         Cooperation.

                  (a) Buyer shall pay, as and when due, all emissions fees,
         permit fees and utility bills due and payable after the Effective Time,
         and Seller shall reimburse Buyer within thirty (30) days after invoice
         for any amounts under such bills attributable to any period prior to
         the Effective Time. Buyer shall pay, and be entitled to collect, any
         rents due subsequent to the Effective Time under leases which are
         assumed Leases, and Seller shall either pay, or be entitled to receive
         from Buyer, as the case may be, within thirty (30) days after invoice
         or notice, any amounts attributable to any period prior to and
         including the Effective Time.

                  (b) Buyer shall file, or cause to be filed, all required
         reports and returns incident to all ad valorem taxes, real property
         taxes, personal property taxes and similar

                                       75
<PAGE>

         obligations, which reports and returns are due on or after the
         Effective Time and shall pay or cause to be paid to the taxing
         authorities all such taxes reflected on such reports or returns even if
         same are for periods prior to the Effective Time and Seller shall
         reimburse Buyer within thirty (30) days after invoice for any such
         taxes and similar obligations which are attributable to any period
         prior to the Effective Time.

                  (c) Seller and Buyer agree to cooperate with the other in the
         event one of them is involved in a tax controversy concerning the
         Assets and the other has either records or personnel which may be of
         assistance to the Party engaged in the controversy. Seller and Buyer
         further agree that if, in such Party's view, such cooperation becomes
         an unreasonable financial burden, they will agree upon a reasonable
         method of reimbursement to the burdened Party.

                  (d) If a Party hereto makes or has made any payment to a third
         party pursuant to any assigned contract, lease, agreement or
         commitment; and (i) such payment is made in respect of work performed,
         services provided or goods delivered during a period of time which
         includes the Effective Time; or (ii) the Effective Time intervenes
         between the making of such payment and the performance of the work or
         services or delivery of goods, the Parties will allocate the burden of
         such payment in a manner which reflects the relative benefit of such
         work performed, services provided or goods delivered to each Party;
         provided, however, it shall be presumed that any work performed,
         services provided or goods delivered prior to and including the
         Effective Time are for the benefit of Seller and any work performed,
         services provided or goods delivered after the Effective Time are for
         the benefit of Buyer.

12.7     Assets Not Assigned at Closing.

                  To the extent that any of the Assets including Intellectual
Property, Licensed Technology, Contracts, Leases and Easements, Marketers
Agreements or Permits that would otherwise be assigned under this Agreement, as
contemplated by Section 3.2(a)(iii), are not capable of being assigned,
transferred, subleased or sublicensed without the consent of, or waiver by, any
other Party thereto or any other Person, or if such assignment, transfer,
sublease or sublicense or attempted assignment, transfer, sublease or sublicense
would constitute a breach thereof or a violation of any Legal Requirement, this
Agreement shall not constitute an assignment, transfer, sublease or sublicense,
or an attempted assignment, transfer, sublease or sublicense of any such Asset.
In the event Seller is unable to obtain a required consent, the Seller and Buyer
shall cooperate and use reasonable efforts to implement arrangements designed to
obtain for Buyer (without cost or expense to Buyer beyond that which Buyer would
otherwise pay in customary and ordinary license fees (but not transfer fees), if
any, to a third party licensor for assignment of the license to Buyer) the
benefits and privileges of the applicable asset, instrument, contract, license
or document and assuming implementation of such alternative agreement, the
failure to obtain the consent will not constitute a failure of a condition to
close. Even if Buyer waives the condition in Section 7.3 with respect to a
particular consent, Seller, for a period of ninety (90) days after Closing, will
continue to use its reasonable efforts with the assistance of Buyer to obtain a
consent to an assignment from Seller to Buyer of each of the Contracts, Leases,
Easements and Permits listed which assignments are not made at Closing.

12.8     Relationship of the Parties.

                  Nothing in this Agreement or the Related Agreements shall be
construed to create any joint venture, partnership, agency or other similar
fiduciary relationship between the Parties

                                       77
<PAGE>

hereto or thereto. The Parties to this Agreement and the Related Agreements are
nothing other than independent contractors for the sale or purchase of specific
property, goods or services. The Parties acknowledge that, for purposes of this
Agreement and the Related Agreements, (i) none of the Parties or their
Affiliates shall be considered to be the agent, representative, employee,
master, or servant of the others for any purpose, (ii) none of the Parties or
their Affiliates shall have any obligation to manage or operate any of their
respective businesses with any duty or standard of care to the other Party or
their Affiliates, and (iii) none of the Parties or their Affiliates have any
authority, right or power to enter into a contract or commitment, assume any
obligation or make any representation or warranty on behalf of the others
(except as expressly specified in this Agreement or the Related Agreements). The
Parties agree and acknowledge that except as expressly provided herein or in the
Related Agreements, none of the Parties or their Affiliates shall owe duties,
fiduciary or otherwise to the other. The Parties and their Affiliates are, and
will be after Closing, competitors with the right to pursue any business
opportunity for their respective individual benefit and make no representation
or warranty regarding the manner in which they will conduct their respective
businesses and operations. None of the Parties or their Affiliates shall have
any obligation to refrain from (i) engaging in the same or similar activities or
lines of business as the Parties or their Affiliates, (ii) developing or
marketing any products or services that compete, directly or indirectly with
those Parties or their Affiliates, (iii) investing or owning any interest
publicly or privately in, or developing a business relationship with, any Person
engaged in the same or similar activities or lines of business as, or otherwise
in direct or indirect competition with, the Parties or their Affiliates, or (iv)
doing business with any client or customer of the Parties or their Affiliates.
None of the Parties or their Affiliates shall have any obligation to offer any
business opportunity (except as expressly specified in this

                                       78
<PAGE>

Agreement or the Related Agreements) and may modify or otherwise change any of
their respective businesses or operations at any time.

12.9     PMPA Compliance.

                  (a) To the extent the Marketers Agreement constitute a
         "franchise relationship," as that term is defined in the Petroleum
         Marketing Practices Act, 15 U.S.C., Section 2801 et seq. ("PMPA"),
         Seller and Buyer will comply with all aspects of the PMPA and any other
         applicable law in the assignment and assumption of the Marketers
         Agreement.

                  (b) Seller shall indemnify and hold Buyer, its Affiliates,
         agents and employees harmless from and against each and every loss,
         cost, claim, obligation, damage, liability, payment, fine, penalty
         cause of action, judgment (including expert witness fees and attorneys'
         fees awarded to any franchisees as part of a judgment), lien or
         expense, including, but not limited to, reasonable attorneys' fees and
         other litigation expense (a "PMPA Claim") to the extent that any such
         PMPA Claim seeks to invalidate or claim the invalidity of Seller's
         assignment of its franchise agreements to Buyer, unless such PMPA Claim
         is based on any act or omission by Buyer occurring after the Closing
         Date.

                  (c) Buyer shall indemnify and hold Seller, its Affiliates,
         agents and employees harmless from and against each and every PMPA
         Claim of any kind or character which result from, arise out of, or are
         in any way related to Buyer's failure to fulfill its obligations under
         this Agreement or the PMPA, and Buyer's failure to fulfill any
         obligations arising after the Effective Time contained in the Marketer
         Agreements assigned to Buyer by Seller.

14.2     Notification and Third Party Claims.

                  Within thirty (30) days following the determination thereof,
an Indemnified Party shall give the Indemnifying Party written notice of any
matter which an Indemnified Party has determined has given rise to a right of
indemnification under this Agreement, stating the amount of the Damage, if
known, and method of computation thereof, all with reasonable particularity and
containing a reference to the provisions of this Agreement in respect of which
such right of indemnification is claimed or arises ("Claim Notice"), provided
that the failure of the Indemnified Party to provide such 30-day notice shall
only relieve the Indemnifying Party of its obligation to indemnify the
Indemnified Party to the extent that the Indemnifying Party is actually
prejudiced by such failure. The obligations and liabilities of an Indemnifying
Party under this Article 14 with respect to Damages arising from claims of any
third party that are subject to the indemnification provisions of this Article
14 ("Third Party Claims") shall be governed by and contingent upon the following
additional terms and conditions:

                                       83
<PAGE>

                  (a) Within thirty (30) days of the receipt of a Claim Notice
         of a Third Party Claim, the Indemnifying Party shall notify the
         Indemnified Party whether the Indemnifying Party elects to defend such
         Third Party Claim. If the Indemnifying Party so elects, it shall
         undertake the defense thereof by counsel of its own choosing, which
         counsel shall be reasonably satisfactory to the Indemnified Party;
         provided that if a conflict of interest exists between the Indemnified
         Party and the Indemnifying Party with respect to such Third Party
         Claim, or if the Indemnifying Party elects not to defend such Third
         Party Claim, or if the Indemnifying Party fails to notify the
         Indemnified Party within the thirty (30) day notice period that it
         elects to defend such Claim, such Indemnified Party shall be entitled
         to select counsel of its own choosing, in which event the Indemnifying
         Party shall be obligated to pay the reasonable fees and expenses of
         such counsel to the extent that the Indemnifying Party is finally
         determined to be obligated to indemnify the Indemnified Party under
         this Agreement. The Claim Notice of the Third Party Claim by the
         Indemnified Party shall contain all material information known to the
         Indemnified Party with respect to the Third Party Claim and shall
         include copies of materials submitted to the Indemnified Party by the
         relevant third party with respect to the Third Party Claim.

                  (b) If the Indemnifying Party refuses or fails at any time to
         defend the Indemnified Party against any Third Party Claim, the
         Indemnified Party shall have the right to undertake the defense, and to
         compromise or settle such Third Party Claim. Such settlement shall be
         on behalf of and for the account and at the risk of the Indemnifying
         Party to the extent that the Indemnifying Party is finally determined
         to be obligated to

                                       84
<PAGE>

         indemnify the Indemnified Party under this Agreement with respect to
         such Third Party Claim.

                  (c) If the Indemnifying Party elects to undertake and
         diligently pursues the defense of a Third Party Claim hereunder, the
         Indemnifying Party shall control all aspects of the defense and if the
         Indemnifying Party acknowledges in writing its duty to provide full
         indemnification to the Indemnified Party regarding such Third Party
         Claim, the Indemnifying Party may enter into a settlement of such Third
         Party Claim and may settle, compromise or enter into a judgment with
         respect to such Third Party Claim; provided that the Indemnifying Party
         obtains a full and unconditional release of the Indemnified Party or
         otherwise obtains the consent of the Indemnified Party, if it would
         result in the imposition of any non-monetary liability or obligation on
         the Indemnified Party.

                  (d) If the Indemnifying Party elects to undertake and
         diligently pursues the defense of a Third Party Claim hereunder, the
         Indemnified Party shall provide the Indemnifying Party with access to
         all reasonably requested witnesses, records and documents of the
         Indemnified Party relating to any Third Party Claim.

                  (e) The Indemnified Party may participate in the defense of
         any Third Party Claim at its own expense.

14.3     LIMITATION ON INDEMNIFICATION.

                  (a) WITH RESPECT OF ANY CLAIM BY A PARTY FOR INDEMNITY UNDER
         THIS ARTICLE 14 WHICH DOES NOT INVOLVE A THIRD PARTY CLAIM, NO PARTY TO
         THIS AGREEMENT SHALL SEEK, AND AN ARBITRATOR APPOINTED UNDER ARTICLE 15

         CLAIM.

                  (b) SUBJECT TO SUBSECTION (d) BELOW, A PARTY SHALL HAVE NO

14.4     Coordination of Indemnification Rights.

                  (a) Except for any action seeking specific performance and/or
         injunctive relief for the breach of any covenant contained in this
         Agreement, or for common law fraud or deceit, the indemnification
         provided any Person pursuant to this Article 14 shall be such

                                       86
<PAGE>

         Person's sole remedy for any breach by any Party hereto of any
         representation, warranty or covenant contained in this Agreement, or in
         any certificate (to the extent such certificates relate to matters
         covered by the representations, warranties or covenants contained
         herein) required to be delivered in connection herewith, or in
         connection with the consummation of the transactions provided for
         hereby.

                  (b) A Claim Notice in connection with any Section of this
         Article 14 shall be deemed to be a Claim Notice in connection with all
         Sections of this Article 14, pursuant to which the Person asserting
         such claim has any right to be indemnified, defended or held harmless.

                  (c) Notwithstanding any provisions to the contrary contained
         in this Article 14, the right of any Person to be indemnified, defended
         or held harmless in connection with any claim pursuant to any Section
         of this Article 14 shall be reduced to the extent that such Person is
         or has been indemnified, defended and/or held harmless with respect to
         such claim, pursuant to any other provisions of this Agreement or any
         of the Related Agreements.

                  (d) In the event that an Indemnified Party has a right of
         recovery against any third party with respect to any Damages in
         connection with which a payment is made to such Indemnified Party by an
         Indemnifying Party; then (i) such Indemnifying Party shall, to the
         extent of such payment, be subrogated to all of the rights of recovery
         of such Indemnified Party against such third party with respect to such
         Damages; and (ii) such Indemnified Party shall execute all papers
         required and take all action necessary to secure such rights,
         including, but not limited to, the execution of such documents as are

                  (e) In the event of any conflict between this Article 14 and

right to cure, within a reasonable time, not to exceed thirty (30) days after
receipt of written notice, and in a manner reasonably satisfactory to such
Person, any matter giving rise to such obligation to the extent such matter
could reasonably be expected to be cured within such time period; provided,
however, that any such cure shall not relieve or reduce any such obligation to
the extent that such cure is inadequate.

                  All of the representations, warranties and covenants of the
Parties set forth in this Agreement and the obligations of the Parties set forth
in this Article 14 shall survive the Closing.

                                   ARTICLE 15

                               DISPUTE RESOLUTION

15.1     Dispute Resolution.

                  Any controversy or claim ("Claim"), whether based on contract,
tort, statute or other legal or equitable theory (including but not limited to
any claim of fraud, misrepresentation or fraudulent inducement or any question
of validity or effect of this Agreement including this section) arising out of
or related to this Agreement (including any amendments or extensions), or the
breach or termination thereof, shall be settled by mediation and consultations
between the

                                       88
<PAGE>

Parties initiated upon the Notice of any Party. In the event of failure of such
mediation and consultations to settle such Claim in a manner acceptable to all
Parties within thirty (30) days following the Notice, then any such Claim shall
be settled by binding arbitration in accordance with this provision and the then
current CPR Institute for Dispute Resolution Rules for Non-Administered
Arbitration of Business Disputes. The arbitration shall be governed by the
United States Arbitration Act, 9 U.S.C. Sections 1-16, to the exclusion of any
provision of state law inconsistent therewith or which would produce a different
result, and judgment upon the award rendered by the arbitrator may be entered by
any court having proper jurisdiction.

15.2     Place.

                  The arbitration shall be in Houston, Texas.

15.3     Arbitrators.

                  There shall be three (3) independent and impartial arbitrators
of whom Seller appoints one (1) and Buyer appoints one (1) and the third of
which shall be appointed by the two (2) Party-appointed arbitrators in
accordance with the arbitration rules. The arbitrators shall determine the
Claims of the Parties and render a final award in accordance with the
substantive law of the State of Texas, excluding the conflicts provisions of
such law. The arbitrators shall set forth the reasons for the award in writing.

15.4     Statute of Limitations.

                  Subject to Section 14.4, any Claim by a Party for indemnity
under Sections 14(a)(i) or 14(b)(i) shall be time-barred if the asserting Party
commences arbitration with respect to such Claim later than two (2) years after
the Party becomes actually aware of such cause of action. All statutes of
limitations and defenses based upon passage of time applicable to any

                                       89
<PAGE>

such Claim of a defending Party (including any counterclaim or setoff) shall be
tolled while the arbitration is pending.

15.5     Discovery.

                  The arbitrator shall order the Parties to promptly exchange
copies of all exhibits and witness lists, and, if requested by a Party, to
produce other relevant documents, to answer up to ten (10) interrogatories
(including subparts), to respond to up to ten (10) requests for admissions
(which shall be deemed admitted if not denied) and to produce for deposition
and, if requested, at the hearing all witnesses that such Party has listed and
up to four (4) other persons within such Party's control. Any additional
discovery shall only occur by agreement of the Parties or as ordered by the
arbitrator upon a finding of good cause.

15.6     Costs.

                  Unless otherwise specified by the arbitrator, each Party shall
bear its own costs, expenses and attorneys' fees; provided that if court
proceedings to stay litigation or compel arbitration are necessary, the Party
who unsuccessfully opposes such proceedings shall pay all reasonable associated
costs, expenses, and attorneys' fees in connection with such court proceeding.

15.7     Breach.

                  The Parties recognize that irreparable injury will result from
a breach of any provision of this Agreement and that money damages will be
inadequate to fully remedy the injury. In order to prevent such irreparable
injury, the arbitrator shall have the power to grant temporary or permanent
injunctive or other equitable relief. Prior to the appointment of an arbitrator
a Party may, notwithstanding any other provision of this Agreement, seek
temporary injunctive relief from any court of competent jurisdiction; provided
that the Party seeking such

                                       90
<PAGE>

relief shall (if arbitration has not already been commenced) simultaneously
commence arbitration. Such court ordered relief shall not continue more than ten
(10) days after the appointment of the arbitrator (or in any event for longer
than sixty (60) days).

15.8     Consent to Jurisdiction.

                  The Parties hereby consent to the non-exclusive jurisdiction
of the state or federal courts of Texas for the enforcement of any award
rendered by the arbitrators.

                                   ARTICLE 16

                               TECHNOLOGY TRANSFER

16.1     Intellectual Property Owned by Seller.

                  (a) Pursuant to the Related Agreements, Seller is licensing
         certain Intellectual Property to Buyer for use at the Refinery and/or
         in connection with the operation of the Assets, with respect to the
         patented technology listed in Schedule 16.1(a): (i) HF Alkylation
         Technology, (ii) Maxcat Coke Reduction Technology and (iii) Crude
         Assays Database. The KEAS technology is provided for in Subsection
         16.1(c) herein. Trademarks are excluded except as licensed under the
         Trademark License Agreement.

                  (b) With respect to any other Intellectual Property owned by
         Seller or its Affiliates and used or held for use in the Operations.
         Seller hereby grants to Buyer a non-exclusive, royalty-free, fully
         paid-up and perpetual license to use such Intellectual Property in
         Buyer's operations. Such license rights shall be without the right of
         Buyer to extend the use of such Intellectual Property to any other
         activities, operations or facilities of Buyer and shall be without the
         right of Buyer to sublicense such Intellectual Property to third
         parties; however, such license shall be transferable by Buyer to any
         subsequent owner of the Refinery without the consent of Seller.

                                       91
<PAGE>

                  (c) Seller has rights to use Knock Engine Automation System
         ("KEAS") technology in Operations at the Refinery. Seller has
         previously granted an exclusive license to this KEAS technology to
         Waukesha Engine Division of Dresser Industries, Inc. ("Waukesha"). It
         is understood that Seller will retain its rights to the KEAS technology
         for use at other facilities but has no right to license this technology
         to Buyer for use at the Refinery or otherwise; and therefore Buyer will
         be required to obtain a license from the exclusive licensee (Waukesha)
         in order to use this technology in Buyer's operation of the Assets.
         Prior to Closing, Seller shall use reasonable efforts in an effort to
         assist Buyer in obtaining a license to this technology from Waukesha in
         a form and substance acceptable to Buyer. If Seller is unsuccessful in
         obtaining a license from Waukesha for Buyer for this technology in a
         form and substance satisfactory to Buyer, on or before Closing, Seller
         will substitute equivalent assets or arrangement.

16.2     Licensed Technology.

                  (a) With respect to Licensed Technology used or held for use
         in the Operations and that is held by Seller or its Affiliates with an
         unrestricted right to sublicense to third parties (listed in Schedule
         16.1(b) attached hereto), Seller hereby grants to Buyer a non-exclusive
         sublicense, under each applicable license, to use such Licensed
         Technology in Buyer's operations of the Assets. Such sublicense shall
         be under the same terms and conditions under which Seller licenses the
         Licensed Technology. Such sublicense shall be without the right to
         extend to any other activities, operations or facilities of Buyer or to
         any third parties. For the avoidance of doubt, Seller uses and will
         continue to use this Licensed Technology in the operations of other
         refineries of Seller.

                                       92
<PAGE>

         Such sublicense shall be transferable by Buyer to any subsequent owner
         of the Refinery without the consent of Seller.

                  (b) With respect to any Licensed Technology used or held for
         use in the Operations of the Assets and held by Seller or its
         Affiliates without the unrestricted right to sublicense to third
         parties (listed in Schedule 16.1(c) attached hereto), prior to Closing,
         Seller agrees to use reasonable efforts to obtain from the licensor the
         right of Buyer to continue to use such Licensed Technology in Buyer's
         operations of the Assets under the same terms and conditions as those
         under which Seller licenses such Licensed Technology provided that
         Seller has provided such terms and conditions to Buyer. Any fees or
         costs necessary to obtain such right on behalf of Buyer shall be paid
         by Seller. Buyer may, at its option, notify Seller in writing of its
         desire to negotiate directly with the licensor of such Licensed
         Technology, and if Buyer enters into a direct licensing relationship
         with such licensor, Seller shall be under no further obligation with
         respect to such license.

                  (c) It is understood that Licensed Technology was acquired by
         Seller subject to certain third party obligations. In any sublicense by
         Seller to Buyer for the right to use any such third party Licensed
         Technology under this Section, Buyer agrees to assume all obligations
         related to Buyer's use of such Licensed Technology in its operations of
         the Assets. In the event that Seller's rights to the Licensed
         Technology are terminated, then Seller shall provide notice to Buyer of
         such termination, as much before such termination as is reasonably
         practicable under the circumstances, and in such event Seller will use
         its reasonable efforts to accommodate Buyer's reasonable requests that
         would enable Buyer to continue to use such Licensed Technology. The
         foregoing shall not, however, obligate

                                       93
<PAGE>

         Seller to extend to Buyer or maintain for Buyer the right to use such
         third party Licensed Technology in the same manner and to the same
         extent as practiced by Seller prior to the Closing Date, where the
         extension or maintenance of such right would be to the detriment of the
         rights of Seller or any of its Affiliates to practice under its own
         rights and licenses.

16.3     Confidential Technology Information

                  (a) "Confidential Technology Information" shall mean any
         technical information or trade secrets of Seller that are made
         available to Buyer for its use after Closing pursuant to Section
         16.1(b) and that are marked confidential or which by their nature or
         content should be reasonably understood to be confidential; provided,
         however Confidential Technology Information shall not include any
         information that: (i) was available to the public prior to, or becomes
         available to the public subsequent to, the receipt of such Confidential
         Technology Information by Buyer and through no fault of Buyer; or (ii)
         was in the possession of Buyer prior to the receipt of such
         Confidential Technology Information and was not acquired by Buyer from
         a third party under an existing obligation of confidence; or (iii) is
         subsequently received by Buyer from a third party without an obligation
         of confidentiality; or (iv) is independently developed by an employee
         or employees of Buyer not having direct access to such Confidential
         Technology Information.

                   (b) For two years after the Closing Date, Buyer shall
         maintain the Confidential Technology Information in confidence; shall
         restrict the disclosure of Confidential Technology Information to only
         those of its employees who require it in connection with Buyer's
         operation of the Refinery and other Assets; shall not disclose
         Confidential Technology Information to any third party; and shall not
         use Confidential

                                       94
<PAGE>

         Technology Information for any purpose other than in connection with
         Buyer's operation of the Refinery and other Assets.

                  (c) Nothing in this Article 16 shall restrict in any way the
         right of Seller or its Affiliates to use or disclose or permit others
         to use or disclose Confidential Technology Information which it
         possesses and otherwise has a free right to use and disclose.

                  (d) Confidential Technology Information, which is required to
         be disclosed, (i) by any applicable law, stock exchange rules or by any
         applicable judgment, order or decree of any governmental entity having
         jurisdiction or (ii) in connection with the preparation of tax returns,
         communications with governmental authorities with respect thereto or
         proceedings relating to taxes, may be disclosed, provided that Buyer
         discloses such Confidential Technology Information to the least extent
         practicable, and Buyer provides Seller with prompt and reasonable
         notice thereof so that Seller may seek a suitable protective order or
         other appropriate remedy and/or waive compliance with the provisions of
         this Article 16. In the event that such protective order or other
         remedy is not obtained or Seller waives compliance with the provisions
         of this Article 16, and Buyer is required to disclose such Confidential
         Technology Information, Buyer will furnish only that portion of the
         Confidential Technology Information which Buyer is required to disclose
         and, to the extent practicable, Buyer will exercise its best efforts to
         obtain reliable assurance that confidential treatment shall be accorded
         and such Confidential Technology Information so furnished.

                  (e) Buyer shall have a right to disclose Confidential
         Technology Information to service providers, consultants, independent
         contractors and government agencies, as required to operate the Assets
         in the normal course of business (except that any Licensed

                                       95
<PAGE>

         Technology that is prohibited from disclosure pursuant to the terms of
         the third party license agreement covering such confidential
         information shall be subject to the restrictions on disclosure set
         forth in such license agreement), but only if such recipient agrees to
         be bound pursuant to a written obligation of confidentiality and nonuse
         comprising restrictions at least as stringent as provided herein, and
         provided that Buyer and the recipients comply with the restrictions and
         obligations of any grants, assignments, licenses or sublicenses of any
         Intellectual Property or Licensed Technology.

16.4     Limitation of Warranties.

                  ANY ORAL OR WRITTEN REPORT, DATA OR OTHER INFORMATION PROVIDED
TO BUYER PURSUANT TO THIS ARTICLE 16, WHETHER PROVIDED UNDER LICENSE OR
OTHERWISE, SHALL BE PROVIDED ON AN "AS IS" BASIS WITHOUT ANY WARRANTIES, EXPRESS
OR IMPLIED INCLUDING BUT NOT LIMITED TO THE RESULTS OR EFFECTS OBTAINED THROUGH
USE OF INFORMATION, OR THAT IT IS FIT FOR ANY USE INTENDED OR CAN BE USED
WITHOUT INFRINGING THE PATENT OR COPYRIGHT RIGHTS OF A PERSON. WITHOUT ANY
LIMITATION ON THE PRECEDING, ANY IMPLIED WARRANTY OR MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE IS EXPRESSLY EXCLUDED FROM THIS ARTICLE 16 WITH RESPECT
TO ANY INFORMATION PROVIDED UNDER THIS ARTICLE 16. IN NO EVENT WILL ANY PARTY BE
LIABLE FOR LOSS OF PROFITS, OR INDIRECT, CONSEQUENTIAL (EXCEPT FOR BREACH OF
CONFIDENTIALITY) OR SPECIAL DAMAGES RESULTING FROM THE OTHER PARTY'S USE OR
DISCLOSURE OF ANY INFORMATION. The use by Buyer of Intellectual Property or
Confidential Technology Information disclosed under this Article 16 by

                                       96
<PAGE>

Seller to Buyer shall be solely at Buyer's own risk and Seller shall not be
liable for any damage resulting from inaccuracy, incorrectness, unsoundness,
and/or unreliability in the use thereof, whether or not such liability is cause
by the negligence of Seller.

16.5     Default.

                  In the event that any Party hereunder for a period of thirty
(30) days fails materially to perform any of its material obligations or
materially violates any material provisions of this Article 16, a nondefaulting
party may give written notice to the other Party to this Article 16 specifying
the particulars of such failure or violation (hereinafter "Default") and, in the
event the defaulting party shall not remedy or begin to remedy such Default
within thirty (30) days after receipt of such notice, the nondefaulting party
may entirely at its option, in addition to any of the other rights and remedies
permitted under this Agreement, on ten (10) days' written notice to the other
party seek specific performance and/or damages pursuant to the Dispute
Resolution provisions of Article 15. The failure of a Party to insist upon

<PAGE>

                  (c) by Seller or Buyer if the other Party fails to materially
         comply with its covenants and obligations in this Agreement; provided
         that the Terminating Party must give the defaulting Party at least

                                  MISCELLANEOUS

20.1     Entire Agreement; Amendments.

                  This Agreement and the Related Agreements, including their
Exhibits and Schedules, and other writings referred to herein or delivered
pursuant hereto which form a part hereof, including, without limitation, the
Confidentiality Agreement between Seller and Buyer dated June ____, 2002,
contain the entire understanding of the Parties with respect to the subject
matter hereof. There are no restrictions, agreements, promises, warranties,
covenants, or undertakings other than those expressly set forth herein or
therein. This Agreement and the Related Agreements supersede any and all prior
agreements and understandings between the Parties with respect to the subject
matter hereof. This Agreement shall not be amended, altered, or modified except
by an instrument in writing duly executed by the Parties hereto.

20.2     Invalidity.

                  If any provision of this Agreement is held to be illegal,
invalid, or unenforceable under any present or future laws, such provision shall
be fully severable; this Agreement shall be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part of this
Agreement; and the remaining provisions of this Agreement shall remain in full
force and effect, unaffected by the illegal, invalid or unenforceable provision
or by its severance from this Agreement. In lieu of such illegal, invalid, or
unenforceable provision, there shall be

                                      100
<PAGE>

added automatically as a part of this Agreement a provision as similar in terms
to such illegal, invalid or unenforceable provision as may be possible and be
legal, valid and enforceable.

20.3     Effect of Waiver or Consent.

                  No waiver or consent, express or implied, by any Party to or
of any breach or default by any other Party in the performance by such other
Party of its obligations hereunder shall be deemed or construed to be a consent
or waiver to or of any other or subsequent breach or default in the performance
by such other Party of the same or any other obligations of such other Party
hereunder. Failure on the part of a Party to exercise its rights or to complain
of any act of the other Party or to declare the other Party in default,
irrespective of how long such failure continues, shall not constitute a waiver
by such Party of its rights hereunder until the applicable statute of limitation
period has run.

20.4     Limitation on Benefits of this Agreement.

                  No person or entity other than the Parties hereto (or their
respective successors or assigns as permitted hereunder) is or shall be entitled
to bring any action to enforce any provision of this Agreement against either of
the Parties hereto, and the covenants, undertakings, and agreements set forth in
this Agreement shall be solely for the benefit of, and shall be enforceable only
by, the Parties hereto (or their respective successors and assigns as permitted
hereunder).

20.5     Notices.

20.13    Confidentiality.

                  (a) This Agreement, the Related Agreements, the data and
         information provided by Seller to Buyer related to the Assets and the
         sale of the Assets to Buyer, and the discussions and negotiations
         between Seller and Buyer related to this transaction (collectively,
         "Transaction Information") are confidential, and Seller and Buyer shall
         each maintain the confidentiality of the Transaction Information until
         the Effective Time. Seller and Buyer shall use reasonable efforts not
         to make disclosure of the Transaction Information to any Person, other
         than its officers, employees, advisers and representatives (or the
         Antitrust Regulatory Authorities) to whom such disclosure is necessary
         or convenient for the completion of the transactions contemplated by
         this Agreement, or any of the Related Agreements, and except in an
         arbitration proceeding as described in Article 15 or as may be required
         by a court of competent jurisdiction. Seller and Buyer shall
         appropriately notify each officer, employee, adviser and representative
         to whom any such disclosure is made, that such disclosure is made in
         confidence and shall be kept in confidence. Nothing herein shall
         prohibit the Parties from disclosing the Transaction Information as may
         be required under applicable securities laws or regulations.

                  (b) Each of Seller and Buyer shall use diligent efforts in
         accordance with customary and reasonable commercial practice, and at
         least with the same degree of skill and care that it would manifest in
         protection of its own confidential information, to protect the
         Transaction Information.

                                      105
<PAGE>

                  (c) Each of the Parties shall notify the other promptly, in
         the event that it becomes aware of the unauthorized possession or use
         of the Transaction Information (or any part thereof) by any third
         Person, including any of its officers, employees, advisers or
         representatives. Seller and Buyer shall cooperate with the other in
         connection with the other's efforts to terminate or prevent such
         unauthorized possession or use of its Transaction Information. The
         Party which allowed or made the disclosure of Transaction Information
         to an unauthorized third party shall pay the other's reasonable
         out-of-pocket expenses in so cooperating in protecting its Transaction
         Information, unless the unauthorized possession or use of the
         Transaction Information resulted from the willful misconduct or gross
         negligence of the Party otherwise entitled to reimbursement of its
         expenses.

                  (d) Each of Seller and Buyer acknowledges that the other will
         suffer injury for which the other will not have an adequate remedy at
         law, in the event of a breach of the provisions of this Section 20.13,
         and that the other shall be entitled to injunctive relief as is
         reasonably necessary to prevent or curtail such breach, whether actual
         or threatened; provided, that, in no event (including, but not limited
         to, a willful breach of this Agreement by Seller or Buyer,
         respectively) shall Seller or Buyer be prevented from exercising all of
         the rights granted to it hereunder.

                  (e) Notwithstanding any other provision of this Agreement, the
         obligations of each of Seller and Buyer to maintain the confidentiality
         of the Transaction Information (each in such capacity a "Disclosing
         Party") shall not apply to any portion of the Transaction Information
         that:

                                      106
<PAGE>

                           (i) is or becomes generally available to the public
                  through no fault of the Disclosing Party, including
                  information in the public domain;

                           (ii) the Disclosing Party receives from a third party
                  without any requirement to keep such information secret;

                           (iii) the Disclosing Party can prove was in its
                  possession without any obligation of secrecy at the time of
                  its disclosure; or

                           (iv) the Disclosing Party develops independently of
                  and without reference to or use of the Transaction
                  Information.

                  (f) Seller acknowledges and agrees that, as of the Effective
         Time, nothing herein shall restrict the use by Buyer of the Records,
         the same becoming property of the Buyer as a consequence of the
         transactions contemplated herein. Except for Records, Buyer shall not
         use the Transaction Information for any purpose other than the
         evaluation of the transactions contemplated hereunder.

                  (g) In the event of any inconsistency between the provisions
         of this Section 20.13 and the confidentiality provisions of any Related
         Agreement, the provisions of the Related Agreement shall control with
         respect to any matters addressed by such Related Agreement.

                  (h) The provisions of this Section 20.13 shall remain in force
         for a period of two (2) years from the Effective Time.

                  (i) If the Closing does not occur, Buyer shall within twenty
         (20) days after receiving a written request from Seller return to
         Seller all written Confidential Technical Information which is not a
         Record, including all photocopies of the same.

Agreement, each of the Parties to this Agreement, and the Related Agreements,

preparation, execution and Closing of this Agreement, and the Related
Agreements, and the transactions provided for hereby and thereby.

20.15    Assignment.

         Seller may upon written notice to Buyer transfer or assign any of its
rights but not its obligations under this Agreement to an Affiliate of Seller
which is directly or indirectly wholly- owned by ConocoPhillips. Buyer may upon
written notice to Seller transfer its rights and obligations under this
Agreement to a direct or indirect wholly owned subsidiary of Buyer. Even if
consent is obtained, no Party may make an assignment or delegation, above,
unless such Party delivers to the other Party hereto such written assumptions,
affirmations and/or legal opinions as such other Party may reasonably request to
preserve their rights and remedies hereunder, and Seller and Buyer shall remain
liable to each other for their respective obligations under this and the related
Agreements, notwithstanding any assignment, unless otherwise relieved in writing
by the other Party. This Agreement shall inure to the benefit of and will be
binding upon the Parties hereto and their respective legal representatives,
