                             PRODUCT SALES AGREEMENT
                               GENERAL PROVISIONS


1.   DELIVERIES
     A.   When delivery is point of origin, delivery shall be deemed to have
          been completed:
          1.   To ships or barges when the product has passed the vessel's
               loading flange;
          2.   To tank trucks when the product has actually been delivered into
               the truck;
          3.   To tank cars when the carrier accepts the same for shipment;
          4.   To pipelines upon metering of the product.
     B.   When delivery is point of destination, delivery shall be deemed to
          have been completed:
          1.   From ships or barges when the product has passed the vessel's
               discharge flange;
          2.   From tank trucks when truck has been placed at buyer's facilities
               for unloading;
          3.   From tank cars when carrier delivers same at the destination;
          4.   From pipeline upon metering of the product.
     C.   When by an in-line product transfer, delivery shall be deemed to have
          been completed upon execution of the order by the pipeline carrier.
     D.   If any common or contract carrier trucks are used, Warren shall not be
          liable to Buyer for quantity or quality of product.  After completion
          of loading at the point of origin, Buyer agrees that the handling,
          care or use of product delivered as herein provided shall thereafter
          be at Buyer's sole risk and expense.
2.   MEASUREMENT--Measurement shall be done in the manner customarily utilized
     at the point of delivery so long as it is in accordance with one of the
     following alternatives:
     A.   On all deliveries into/out of tank cars, the quantity shall be
          determined by official tank car capacity tables, meters with no vapor
          return, or by weighing, in accordance with GPA Publication 8162 and
          all revisions thereof.
     B.   On all deliveries into/out of transport and tank truck equipment,
          quantities shall be determined by meter with no vapor return, slip
          tube, rotary gauging device or weighing, in accordance with GPA
          Publication 8162 and all revisions thereof.
     C.   On all deliveries into/out of pipeline, quantity shall be determined
          by turbine or positive displacement pipeline meter in accordance with
          API Manual of Petroleum  Measurement Standards and all revisions
          thereof.
     D.   On all deliveries to/from ships or barges, shore tank or turbine or
          positive displacement meter measurements shall determine quantity,
          unless otherwise agreed upon.  Use of meters shall not allow vapor
          return.
     E.   All quantities shall be corrected to 60 degrees Fahrenheit and
          equilibrium vapor pressure at 60 degrees Fahrenheit.
     F.   Volume and compressibility correction factors shall be determined from
          referenced API tables or computer programs used to generate these
          tables.
3.   PASSAGE OF TITLE AND WARRANTY OF TITLE--Title to the product and risk of
     loss shall pass to Buyer upon delivery.  Warren warrants to Buyer that it
     has title to the product(s) delivered by it hereunder and the right to
     deliver same, and agrees to indemnify, defend and hold the Buyer harmless
     from and against any loss, claim or demand by reason of any failure of such
     title or breach of this warranty.  Except as set forth in this paragraph 3
     and elsewhere herein, WARREN MAKES NO OTHER WARRANTY WITH RESPECT TO THE
     PRODUCT OR OTHERWISE, INCLUDING WITHOUT LIMITATION, ANY WARRANTY OF
     MERCHANTABILITY OR OF FITNESS FOR A PARTICULAR PURPOSE.
4.   TAXES--Any tax, duty, toll, fee, impost, charge or other exaction, or the
     amount equivalent thereto, now or hereafter imposed, levied or assessed by
     any governmental authority upon, measured by, incident to or as a result of
     the transaction herein provided for, or the transportation, importation,
     production, manufacture, use or ownership of the goods or source materials
     thereof which are the subject matter of this Agreement, shall, if
     collectible or payable by Warren, be paid by Buyer on demand by Warren.
     Notwithstanding the foregoing, it is understood and agreed that any
     personal property taxes levied or assessed by any governmental authority
     upon the value of the products covered by this Agreement shall be paid by
     the party having title thereto at the time of such assessment.  Buyer shall
     furnish Warren proper exemption certificate where tax exemption is claimed
     on any or all product(s) delivered hereunder, or shall pay such taxes.
5.   FUTURE OBLIGATIONS--SUPPLIER/PURCHASER RELATIONSHIP--This Agreement is
     freely entered into between the parties hereto.  It does not reflect or
     grow out of any previously existing legal obligation which either party may
     have to the other to supply any petroleum product.  Part of the
     consideration for this Agreement is each party's express agreement that
     neither party expects or desires that this Agreement form the basis of any
     additional future obligation of either party to supply any petroleum
     product to the other.  To the extent that under present or future laws or
     regulations this Agreement may give rise to such obligations, each party
     hereby waives in advance its right to enforce any such obligation and upon
     submittal of written notice of termination by one party to the other under
     this Agreement, it is agreed that both parties intend to terminate any such
     additional future supplier/buyer relationship which may be created by this
     Agreement under such laws or regulations.  Additionally, at any time
     hereafter, the parties agree to submit and/or execute documentation in
     compliance with the then applicable laws and regulations as may be
     necessary to evidence such termination insofar as the parties are
     concerned.  The parties further agree to obtain any other consents or
     authorization required under the then applicable laws and regulations
     insofar as reasonably possible to give effect to the intent hereof.
6.   GOVERNMENT REGULATIONS & LAW--Warren warrants that the product it delivers
     hereunder will be produced and delivered in full compliance with all
     applicable federal and state laws and regulations and all Presidential
     Proclamations which may be applicable.  This agreement shall be construed
     in accordance with the laws of the State of Oklahoma including the Uniform
     Commercial Code.  Buyer agrees to comply with the provisions contained in
     Exhibit "B" attached hereto, to the extent that such provisions are legally
     applicable to Buyer.
7.   FORCE MAJEURE--If either party is rendered unable, wholly or in part, to
     perform its obligations under this Agreement (other than to make payments
     due hereunder) due to force majeure, defined herein as acts of God, flood,
     fire, explosion or storm; transportation difficulty; strike, lockout or
     other industrial disturbance; war or any law, rule, order or action of any
     court or instrumentality of the federal or any state government;
     exhaustion, reduction or unavailability of products from one or more of the
     sources of supply from which deliveries are normally made hereunder, or
     exhaustion or unavailability or delay in delivery of any material or
     product necessary in the manufacture of the product(s) deliverable
     hereunder; or any other cause or causes beyond its control whether similar
     or dissimilar to those stated above, then in any such event, it is agreed
     that the affected party shall give promptly after the occurrence of force
     majeure notice and full particulars of such force majeure to the other
     party, the obligations of the affected party shall be suspended for the
     duration of such inability to perform but for no longer period, and such
     cause shall, so far as possible, be remedied with all reasonable dispatch.
     Force majeure shall also include the failure of any third party pipeline,
     through no fault of the parties hereto, to accept the referenced products
     for transportation to or from Warren's facilities.
8.   ASSIGNMENT--This Agreement shall extend to and be binding upon the parties
     hereto, their heirs, executors, administrators, successors and assigns; but
     it is expressly agreed that neither party shall voluntarily assign this
     Agreement without the prior written consent of the other.
9.   NOTICE--Any notice hereunder shall be in writing and shall be delivered
     personally, by mail, by telex, or by telegram to the address first
     hereinabove set forth, unless changed by notice.  Such notice shall be
     deemed to have been given on the date of the delivery thereof.
10.  WAIVER--The waiver by either party of the breach of any provision hereof by
     the other party shall not be deemed to be a waiver of the breach of any
     other provision or provisions hereof or of any subsequent or continuing
     breach of such provision or provisions.
11.  ALTERATIONS--No oral promises, agreements or warranties shall be deemed a
     part hereof, nor shall any alteration or amendment of this Agreement, or
     waiver of any of its provisions, be binding upon either party hereto unless
     the same be in writing, signed by the party charged.
12.  INSPECTION--Unless otherwise specified, Buyer will provide gauging,
     sampling, and testing at no charge to Warren.  Either party may secure
     outside inspectors to perform this work and if this is done, the payments
     for these services will be shared equally among the parties unless some
     other arrangement for payment is mutually agreed upon.
13.  MARINE PROVISIONS--If delivery of any products hereunder is to be
     accomplished by waterborne transportation, the provisions set out in the
     "Marine Provisions" attached hereto and made a part hereof shall apply to
     such deliveries.
14.  INVOICES AND TERMS OF PAYMENT--Invoices will be prepared by Warren and
     transmitted to the Buyer from time to time during the month.  Unless
     otherwise specified, payment is due within ten (10) days after receipt of
     invoice.
15.  FINANCIAL RESPONSIBILITY--If in the judgment of Warren the financial
     responsibility of Buyer becomes impaired or unsatisfactory, advance cash
     payments or acceptable security including, but not limited to a letter of
     credit from a financial institution acceptable to Warren shall be given by
     Buyer upon demand of Warren, and Buyer's failure to abide by the provisions
     of this Paragraph shall be considered a breach hereof and in such event
     payment for all products delivered hereunder shall be due and owing and
     shall be paid immediately, and Warren may without waiving any rights or
     remedies it may have, withhold further deliveries until such payment or
     security is received.  Buyer's duty to provide the hereinabove credit
     assurance shall be a condition precedent to Warren's obligation to perform
     under this agreement.
16.  CONFLICTS OF INTEREST--No director, employee or agent of either party shall
     give or receive any commission, fee, rebate, gift or entertainment of
     significant cost or value in connection with this Agreement.  Any
     representative(s) authorized by either party may audit the applicable
     records of the other party solely for the purpose of determining whether
     there has been compliance with this paragraph.
17.  AUDIT--Each party and its duly authorized representatives shall have access
     to the accounting records and other documents maintained by the other party
     which relate to the product being delivered to the other party under this
     Agreement and shall have the right to audit such records once a year at any
     reasonable time or times during the terms of this Agreement and for two
     years after the year in which this Agreement terminates.  Neither party
     shall make claim on the other for any adjustment after said two-year
     period.
18.  QUALITY--Any requirements of customer pertaining to potential contaminants
     and/or specific hydrocarbon composition not listed in Warren's product
     specification must be identified by customer and allowable concentrations
     agreed to in writing by both parties prior to delivery of product to be
     effective under this Agreement.
19.  WARREN'S TANK CARS--Unless Warren's tank cars are unloaded and returned to
     railroad, Buyer shall be liable to Warren for rental at the rate of
     ________________ for each day or fraction thereof in excess of
     ________________ days (LPG cars).  Tank cars shall not be diverted without
     Warren's written consent.
20.  PRICES--Prices at destination include allowance for transportation charges
     at lowest applicable common carrier rate between shipping point and actual
     destination.  Warren reserves the right to add other shipping points and to
     change the shipping points on which destination prices are based.  Notice
     of any such additions or changes in shipping points shall be given to Buyer
     in writing and unless objected to within ten days after receipt, said
     shipping points shall be deemed accepted by Buyer.  Deletions of shipping
     points shall be made in like manner with like effect.  Destination prices
     are subject to adjustment with changes in common carrier freight rates and
     any changes in applicable freight rates shall be for Buyer's account.
     Unless otherwise provided, if common carrier is employed, transportation
     charges shall be paid by consignee directly to carrier.

     If prices are based on quotations in  industry publications, quotations
     published on dates of shipment shall apply.  If no quotations for date of
     shipment are published in designated industry publication, the last
     previous quotations in such publication shall govern.



                                                         PRODUCT SALES AGREEMENT
                                                                    ATTACHMENT A

                                                                  (PSA #S-40844)


1.   SHORTAGE OF PRODUCTS.  Due to uncertainties in the supply/demand situation,
     Warren may not have sufficient supplies of said product to be delivered
     hereunder from its then contemplated sources of supply to meet the full
     requirements of all of its customers, contract or otherwise.  Whenever that
     situation exists and regardless of whether Warren's performance hereunder
     is otherwise excused, Warren shall have, in addition to any other rights
     Warren may have under this Agreement, the right to reduce deliveries of
     such product on any basis which in Warren's opinion is equitable, allowing
     for such priorities to such classes of customers as Warren deems
     appropriate.  No such priorities to such classes of customers as Warren
     deems appropriate.  No such reduction need be made up.  If any such
     reduction occurs, Buyer shall have the option to accept such reduction
     occurs, Buyer shall have the option to accept such reduction or to
     terminate this Agreement as to any or all products by fifteen (15) day's
     notice to Warren given at any time within thirty (30) days after the notice
     of reduction.

2.   BRAND NAMES.  Buyer agrees not represent, or authorize or permit any other
     person to represent, that the product delivered hereunder is the product of
     Warren.  All products delivered to Buyer hereunder shall be used for sold
     under Buyer's own brand names or under brand names approved by Warren, and
     Buyer shall not authorize or permit said product to be used or sold under
     any other brand names.

3.   CONDUCT OF BUYER'S BUSINESS.  Buyer agrees to conduct all operations in
     strict compliance with all applicable law, ordinances, and regulations of
     governmental authorities.  Buyer in the performance of this Agreement is
     engaged in an independent business and nothing therein contained shall be
     construed as giving to Warren any right to control Buyer in any way in its
     performance of this Agreement.  Warren has no right to exercise control
     over any of the Buyer's employees.  All employees of Buyer shall be
     entirely under the control and direction of Buyer who shall be responsible
     for their actions and omissions.
