                (1)    the sum of twenty one million five hundred thousand U.S.
                       Dollars (U.S. $21,500,000) to the bank designated by

        B.     At Closing, there shall be a calculation of a Balancing Payment.
               The Balancing Payment shall be the net sum of all amounts

               Seller to Purchasers.

               (1)     In the event that the combined Adjusted Working Capital
                       (as hereinafter defined) of the Companies (i) is less
                       than $0.00, the Balancing Payment shall be reduced in
                       the amount by which the Adjusted Working Capital of the
                       Companies is less than $0.00, or (ii) exceeds $0.00, the
                       Balancing Payment shall be increased in the amount by
                       which the Adjusted Working Capital of the Companies so
                       exceeds $0.00.  The term "Adjusted Working Capital"
                       shall mean the sum of:  the cash, securities and cash
                       equivalents, accounts receivable (minus reserves
                       therefor), crude oil, fuel, materials and supplies, and
                       materials in transit (less reserves therefor), prepaid
                       expenses (including Tax and lease expenses) and other
                       current assets of the Companies as at the Effective
                       Date, less the sum of all current liabilities (which
                       shall not include any liability for disputed royalty as
                       referenced Schedule E) of the Companies as at the
                       Effective Date, all as determined





                                       4
   9

                       in accordance with generally accepted accounting
                       principles employed by the Companies on a basis
                       consistent with prior periods and exclusive of any
                       deferred income taxes.  For purposes of calculating
                       Adjusted Working Capital, the value of any unsold crude
                       oil inventory of the Companies in storage on the
                       Conkouati on the Effective Date shall be included in
                       current assets, shall be measured as of 12:01 a.m. Congo
                       time on the Effective Date and shall be valued based on
                       the net price per barrel received by the Companies for
                       the first sale of crude oil following the Effective
                       Date.  In addition, any unsold crude oil lifted from the
                       Conkouati prior to the Effective Date shall be included
                       in such current assets (to the extent not otherwise
                       included in such current assets) at the actual net price
                       received by the Companies, less the royalty and other
                       amounts payable by the Companies with respect thereto
                       (to the extent not otherwise included in such current
                       liabilities).

                       For purposes of both current assets and current
                       liabilities, amounts in local currency will be converted
                       into U.S.  dollars using the exchange rate available
                       from BIDC - Pointe Noire (i) on the Effective Date for
                       purposes of Article 3.B(l), and (ii) for purposes of
                       Article 3.B(2) through (4), on the first business day of
                       the month in which Closing occurs.

               (2)     The Balancing Payment shall be adjusted to reflect
                       intercompany transfers of cash ("Transfers") between the
                       Effective Date and the Closing.  All Transfers from the
                       Companies to Seller and its Affiliates (other than the
                       Companies) shall be subtracted from the sum of all
                       Transfers from Seller and its Affiliates (other than the
                       Companies) to the Companies.  If the result so obtained
                       is a positive amount, the Balancing Payment shall be
                       increased by such amount.  If the result so obtained is
                       a negative amount, the Balancing Payment shall be
                       reduced by such amount.  Transfers do not include
                       payments of receivables and receipts of payables as
                       specified in Article 3.B(4) below.

               (3)     The Balancing Payment shall be increased by all capital
                       contributions by Seller to the Companies between the
                       Effective Date and the Closing insofar as such capital
                       contributions do not constitute Transfers.

               (4)     Receivables and payables between the Companies and their
                       Affiliates on the date of Closing shall be offset.  All
                       of the payables owed by the Companies to Seller and its
                       Affiliates (other than the Companies) on the date of
                       Closing shall be subtracted from the sum of all
                       receivables owed by the Seller and its Affiliates (other
                       than the Companies) to the Companies on the date of
                       Closing.  If the result so obtained is a positive
                       amount, the Balancing Payment shall be reduced by such
                       amount.  If the result so obtained is a negative amount,
                       the Balancing Payment shall be





                                       5
   10

                       increased by such amount.  All of the receivables and 
                       payables that have been offset shall be cancelled.

               (5)     Recognizing that the resolution of the royalty issue as
                       addressed in Schedule E will result in increased royalty
                       payments being due from the Companies in the future, the
                       Balancing Payment shall be reduced by an amount (the
                       "Royalty Adjustment") equal to U.S. Dollars two million
                       three hundred thousand (U.S. $2,300,000).

               (6)     In order to reflect Purchasers' contribution to the
                       Companies' share of the signature bonus paid to the
                       Government with regard to Amendment No. 2 to the
                       Convention, the Balancing Payment shall be increased by
                       an amount equal to U.S. Dollars one million (U.S.
                       $1,000,000).

        C.     No fewer than ten (10) days prior to Closing, Seller shall
               prepare and deliver to Purchasers an estimated Balancing Payment
               statement as of the date of Closing.  Such Balancing Payment
               shall be reflected in the Promissory Note as provided in 3.B
               above.  Within ninety (90) days following the date of Closing,
               Purchasers shall prepare and deliver to Seller a final Balancing
               Payment statement as of the date of Closing.  Within thirty
               calendar days after Seller's receipt of the final Balancing
               Payment statement, Purchasers and Seller shall endeavor to agree
               on the final adjustments of the Balancing Payment.  If Seller
               and Purchasers cannot agree on the final Balancing Payment, the
               Houston Office of the firm of Price Waterhouse is designated to
               act as an arbitrator and to decide all points of disagreement
               with respect to the final Balancing Payment, such decision to be
               binding on both parties.  The costs and expenses of the
               arbitrator shall be shared equally by Seller and Purchasers.
               Notwithstanding the Balancing Payment being reflected in the
               Promissory Note as set forth above, payments pursuant to the
               final Balancing Payment shall be made in cash.  Should any
               adjustment be necessary to the Balancing Payment as determined
               at Closing, the party owing funds to the other shall pay such
               funds within thirty (30) days following the date of agreement or
               the decision of the arbitrator.

4.      Further Consideration

        A.     As further consideration, Purchasers shall cause the Companies
               to pay Seller a Production Payment based on the crude oil
               produced and sold by the Companies after the Effective Date as
               set forth in Schedule B.  Purchasers shall use reasonable
               efforts to sell the crude oil to third parties in arms length
               transactions in a manner which will achieve the best available
               net back value FOB the Conkouati for the product.  Should the
               crude oil be marketed by an Affiliate of Seller pursuant to an
               Agency Agreement or other agreement with Purchasers, Purchasers
               shall be deemed to have met such "reasonable efforts"
               requirement.





                                       6
   11

        B.     Payments made pursuant to the Production Payment shall be made
               by the Companies in U.S. dollars from a United States bank
               account to a bank account of Seller in the United States, which
               account shall be designated in writing.  The Purchasers further
               agree that no payments pursuant to the Production Payment will
               be deducted from the income of any taxpayer for Congolese income
               tax purposes.

        C.     APC and the Purchasers shall reach an agreement as to the value
               of the Production Payment and shall both report consistently
               with such agreed upon value for U.S. federal income Tax
               purposes.  If the parties cannot agree upon a value, the parties
               shall submit the issue to an agreed upon reputable appraiser
               with expertise in such valuations and shall both report
               consistently with the valuation determined by such appraiser.

        D.     Seller shall be entitled to recoup the Royalty Adjustment, as
               determined in Article 3.B(5), in the manner set forth this
               Article 4(D).  Within forty (40) days after the end of each
               quarterly period in which IA(n) (hereinafter "Payout Amount") is
               greater than zero, Purchasers shall pay Seller an amount equal
               to 50% of IA(n), determined as set forth below, until the sum of
               all such payments shall equal the Royalty Adjustment, plus
               interest at a rate of 7.0% per annum on the unrecouped balance
               of said Royalty Adjustment.

               For period n = 1:

                       IA(l) = IA(O) X (1.020833) + NCF(l); and

               For all periods other than n (1):

                       IA(n) = IA(n-1) X (1.06250) + NCF(n)

               Where:

                       n =            the quarterly period in question, with 
                                      n(l) being the one month period ending
                                      December 31, 1993.

                       IA(n) =        Payout Amount at the end of the quarterly
                                      period "n", where IA(O) = $30,200,000,
                                      expressed as a negative number.

                       NCF(n) =       Net Cash Flow during the quarterly period
                                      "n".  For purposes of this Article 4(D),
                                      "Net Cash Flow" shall mean proceeds from 
                                      the sale of (i) the Companies' total 
                                      Participating Interest share of 
                                      production and (ii) the Companies' 
                                      total entitlement to Hydro-Congo's
                                      Participating Interest share of
                                      production; LESS, applicable






                                       7

                                      royalty payments to the Government and
                                      all Costs and Expenses incurred during
                                      such quarter.  "Costs and Expenses" shall
                                      include all costs including capital
                                      costs, direct operating costs, indirect
                                      operating costs and administrative costs
                                      as chargeable to the Joint Account under
                                      the JOA, Taxes paid on the total
                                      production sold by the Companies and
                                      Production Payments.  For purposes of
                                      computing Net Cash Flow, the principle of
                                      depreciation of capital costs shall not
                                      be applicable.  Net Cash Flow shall be
                                      negative in any quarter in which all
                                      payments exceed all receipts.

        E.     Purchasers shall afford to the officers, attorneys, accountants
               and other authorized representatives of Seller at Seller's sole
               risk and expense, free and full access upon reasonable notice to
               the accounting and production books and records of the Companies
               in order that such individuals may have full opportunity to make
               such examinations and audits as Seller shall deem reasonably
               necessary for the purposes of determining the accuracy of the
               payments made for the recoupment of the Royalty Adjustment as
               provided in Article 4.D., provided such examinations shall not
               unreasonably interfere with the operations of the Companies and
               shall be carried out during regular business hours.  Seller
               shall have the right to make such copies as it deems necessary
               of any such accounting and production books and records.  Seller
               shall keep the results of such examinations confidential and
               shall not reveal the same to any third party without the consent
               of Purchasers.

        F.     The recoupment of the Royalty Adjustment pursuant to Article 4.D
               shall be subordinate to the OPIC Financing Guarantee on terms
               acceptable to OPIC and Seller.

        G.     In consideration for the execution of Amendment No. 2 to the
               Convention, Amoco Congo Exploration Company and Amoco Congo
               Petroleum Company (Amoco Companies) will pay to the Government
               of the Republic of the Congo a signature bonus sum of U.S.
               $2,900,625, representing the Companies' net share of such
               signature bonus.  This payment will be financed one hundred
               percent (100%) by the Companies and shall be treated as a
               Pre-Effective Date liability, with the amount of $2,900,625
               being included as a current liability on the Effective Date for
               purposes of the Balancing payment calculation in Article
               3.B.(l).  As noted in Article 3.B.(6), Purchasers' contribution
               to the Companies' Share of the signature bonus will be included
               in the balancing payment.

5.      Security

        On the date that this Agreement is signed, Purchasers shall cause
        Banque Paribas, Houston Agency to issue an Irrevocable Standby Letter
        of Credit in the form attached





                                       8
   13

        hereto as Schedule C, to secure certain aspects of the performance of
        Purchasers hereunder.  The letter of credit may be drawn by Seller as
        provided therein.

6.      Other Mutual Considerations

        A.     Purchasers have reviewed the assets of the Companies and agree
               to accept those assets at Closing on an "as-is" basis.  Seller
               shall use reasonable efforts to insure that assets as are
               necessary for the continued operation of the Companies will be
               present in the Companies at Closing.  Purchasers recognize,
               however, that Seller is attempting to sell certain tubulars and
               drilling equipment, as listed in Schedule J which are deemed to
               be surplus to the Companies' operations, but not to include
               those listed in the letter of November 23, 1993, from Gerald
               Livingston to Ron Cole likewise included in Schedule J, and
               certain Submarine Power Cable located in France, which are
               likewise deemed to be surplus, and agree that the proceeds from
               any such sale which occurs prior to Closing shall be treated as
               if they were pre Effective Date proceeds, even if sold after the
               Effective Date.  Any obligations or liabilities for storage or
               handling charges, customs duties and fees or other costs
               incurred prior to Closing relating to such surplus equipment and
               materials shall be reimbursed to the Companies by Seller.

        B.     The Companies shall not terminate the national payroll employees
               of the Companies prior to Closing without the prior consent of
               Purchasers.  The Companies shall retain or assume all of the
               liability associated with the pension/benefit obligations with
               respect to the employees of the Companies who are national
               payroll employees, including but not limited to obligations
               associated with salary, severance and/or retirement benefits.
               Purchasers will indemnify and hold Seller and its Affiliates
               harmless from any claims which may arise from such obligations.
               Purchasers shall not terminate the employment or reduce the
               benefits of any of the Companies' national payroll employees
               (other than for theft or other illegal acts) for a period of one
               (1) year after Closing.  The Seller represents and covenants
               that, at Closing, the Companies shall not have any employees who
               are non national payroll employees or any liability with respect
               to any former employees who are or were non national payroll
               employees, except with regard to potential liability relating to
               the lawsuit Patricia Bettis vs. Amoco Production Company, Amoco
               Corporation and Amoco Congo Exploration Company (hereinafter
               "Bettis Litigation") (See Schedule E).

        C.     Seller shall bear and indemnify Purchasers and Companies with
               respect to any obligations or liabilities associated with the
               plugging and abandonment of any wells drilled prior to the
               Effective Date and not listed on Schedule G.  Purchasers will
               fulfill all of the obligations of the Companies, if any (and/or
               of Seller and its Affiliates, if any), associated with plugging
               and abandonment of the wells drilled under the Convention in
               Marine I and all other abandonment and removal obligations
               related to Marine I; and Purchasers will hold the Seller and its





                                       9
   14

               Affiliates harmless from any claim which may arise from such
               obligations and Purchasers will indemnify the Seller and its
               Affiliates from any claims asserted by any third party with
               regard to such plugging, abandonment or removal.

        D.     Except to the extent any refund was reflected in the balance
               sheet of either of the Companies on the Effective Date as an
               asset, the Companies will transfer and assign to Seller prior to
               Closing all their rights to refunds (whether cash or non-cash)
               or credits received after the Closing Date on account of
               operations prior to the Effective Date.

        E.     Materials on order to the Companies at the time of the Effective
               Date shall constitute a post-Effective Date liability.

        F.     Subsequent to Closing, Purchasers shall cause the Companies to
               operate under the Convention as a prudent operator in accordance
               with generally accepted international petroleum standards.

        G.     Should any of Seller's expatriate personnel remain in Pointe
               Noire beyond Closing, they may remain in their current housing
               and retain their current vehicles for so long as they remain in
               the Congo at no expense to Seller.

        H.     At the time of Closing, the assets of the Companies shall not
               include any Amoco Corporation or affiliate or subsidiary,
               proprietary data, software, technology, or information
               (including manuals) as listed in Schedule K or any data or
               software (including Petroware) procured by Amoco Corporation or
               affiliate or subsidiary from a third party under a
               confidentiality agreement.

7.      Company Name Change

        Prior to Closing, Seller shall cause the name of Amoco Congo
        Exploration Company and the name of Amoco Congo Petroleum Company to be
        changed to Yombo Exploration Company and Yombo Petroleum Company,
        respectively.  Purchasers shall have no right to use the trade name or
        trademark "Amoco" or any derivative thereof for any purpose whatsoever
        and shall cause to be removed all signs or labels with such name.

8.      Closing Transactions

        Should Closing not occur by September 15, 1994, or a mutually agreed
        later date, then any Party may by notice to the other Parties,
        terminate this Agreement, subject to the provisions of Article 5;
        provided, however, that if the Closing does not occur because of the
        failure to conclude the closing agreement with the U.S. Internal
        Revenue Service as referred to in Article 13.G., then this date shall

               course of business, consistent with past practices, or as
               permitted in Article 15.

               shall promptly notify the Purchasers thereof.

10.     Representations and Warranties of Purchasers

        A.     Walter represents and warrants to Seller the following:

               (1)     Walter is duly organized, validly existing and in good
                       standing under the laws of the State of Texas and has the
                       corporate power and authority to carry on its business
                       as now conducted.

               (2)     Walter has the corporate power and authority to enter
                       into and perform this Agreement and all other documents
                       and actions required of Walter hereunder.  All corporate
                       proceedings necessary for Walter's execution and
                       performance of this Agreement and of all documents and
                       actions required of Walter hereunder have been taken; and
                       this Agreement constitutes, and such documents upon their
                       execution by duly authorized officers of Walter will
                       constitute, the valid and binding obligations of Walter
                       enforceable in accordance with the terms hereof, except
                       as may be limited by applicable bankruptcy, insolvency,
                       and moratorium and other laws affecting the enforcement
                       of creditors' rights in general and by general principles
                       of equity (whether applied in a proceeding at law or in
                       equity); provided, however, that the inclusion of the
                       foregoing exception shall not be construed to waive,
                       impair, diminish or reduce, or to expand or create, any
                       right, power, privilege or benefit of Walter hereunder,
                       and, in particular, but not by way of limitation, shall
                       not impair any right of Walter to contest the propriety
                       of any bankruptcy, insolvency, moratorium, equitable or
                       other proceeding.  No other act, approval, or proceeding
                       on the part of Walter or the holders of any class of its
                       equity or debt securities or any other person or entity

                       certificate of incorporation or by-laws and will not

                       their respective directors, employees, representatives
                       and agents, disclaim any representations or warranties
                       concerning the profitability of the Companies, the

                       affecting the enforcement of creditors' rights in

                       hereunder.  All corporate proceedings necessary for
                       Nuevo Holdings's execution and performance of this
                       Agreement and of all documents and actions required of

                       will constitute, the valid and binding obligations of
                       Nuevo Holdings enforceable in accordance with the terms
                       hereof, except as may be limited by applicable
                       bankruptcy, insolvency, and moratorium and other laws
                       affecting the enforcement of creditors' rights in
                       general and by general principles of equity (whether
                       applied in a proceeding at law or in equity); provided,
                       however, that the inclusion of the foregoing exception
                       shall not be construed to waive, impair, diminish or
                       reduce, or to expand or create, any right, power,
                       privilege or benefit of Nuevo Holdings hereunder, and,
                       in particular, but not by way of limitation, shall not
                       impair any right of Nuevo Holdings to contest the
                       propriety of any bankruptcy, insolvency, moratorium,
                       equitable or other proceeding.  No other act, approval,
                       or proceeding on the part of Nuevo Holdings or the
                       holders of any class of its equity or debt securities or
                       any other person or entity is required to authorize the
                       execution, delivery and performance of this Agreement by
                       Nuevo Holdings.

               (3)     Nuevo Holdings is purchasing the Shares for its own
                       account for investment purposes and not with a view to,
                       or for sale in connection with, any distribution
                       thereof.  Nuevo Holdings undertakes that the Shares
                       shall not be sold, transferred, offered for sale,
                       pledged, hypothecated or otherwise disposed of in
                       violation of any applicable securities laws or
                       regulations.

               (4)     Nuevo Holdings hereby acknowledges and affirms that it
                       has made its own independent investigation, analysis and
                       evaluation of the Companies and their properties, assets
                       (including its own estimate and appraisal of the extent
                       and value of petroleum reserves), business, financial
                       condition, operations and prospects and have the
                       capacity to evaluate the merits and risks of the
                       acquisition of the Shares.

               (5)     To the best of Nuevo Holdings's knowledge and belief,
                       the making and performance of this Agreement by Nuevo
                       Holdings will not violate any provisions of any laws,
                       rules, regulations, decrees, orders or judgments or any
                       provision of Nuevo Holdings's certificate of
                       incorporation or by-laws and will not result in the
                       breach or violation of, or constitute a default under,
                       any contractual agreement of Nuevo Holdings or require
                       any consent under Nuevo Holdings's certificate of
                       incorporation or by-laws or any law or regulation to
                       which Nuevo Holdings or any of its Affiliates is
                       subject, or any provision of any material indenture,
                       mortgage, lien, lease agreement, instrument, order,
                       arbitration award, judgment or decree to which Nuevo
                       Holdings, or any of its Affiliates is a party or by
                       which Nuevo Holdings or any of its Affiliates or any
                       other respective assets or properties are bound.

               (6)     Nuevo Holdings acknowledges that Seller and the
                       Companies and their respective directors, employees,

                       or warranties concerning the profitability of the
                       Companies, the markets for the Companies products or,
                       except as otherwise expressly provided herein, the
                       capabilities and condition of the Companies or the wells
                       or other facilities in which they hold an interest, and
                       any representations or warranties other than those
                       expressly set forth in this Agreement.

        E.     Purchasers jointly represent and warrant that they have received
               a commitment for political risk insurance and for financial
               guarantees for third party financing from OPIC in a form
               acceptable to Purchasers.

11.     Additional Agreements, Covenants, Rights and Obligations

        A.     Purchasers and Seller shall cooperate and use their best efforts
               to secure any approvals or consents which may be legally or
               contractually required from the Government of Congo, the
               Government of the United States or other governmental
               authorities, or any other entity for the transactions
               contemplated by this Agreement.  Purchasers and Seller shall
               keep each other advised on a timely basis of the steps proposed
               to be taken to obtain such approvals and consents and the
               results thereof.

        B.     Purchasers and Seller shall issue such notices to third parties
               as may be required by law, regulations, rules, decrees or orders
               to inform them of the sale and purchase of the Companies.

        C.     The Parties have determined that the preferential rights
               provided under the JOA will not be triggered by the transaction
               contemplated by this Agreement and that therefore the notices in
               regard to such rights should not be given to the JOA Partners.
               Any assertion by a JOA Partner of such a preferential right
               shall not be considered a breach of any warranty given by
               Seller.

        D.     Purchasers and Guarantors further covenant and represent:

               (1)     Purchasers were each formed solely for the purpose of

                       had no income, had no operating assets, had
                       substantially no liabilities, and conducted no
                       activities that were not related to the acquisition of
                       the Shares.

               (3)     Purchasers have furnished to Seller correct and complete

                       with such financing as is necessary to consummate the
                       purchase of the Shares.

               (4)     To accomplish the acquisition of the Shares, Walter will
                       merge with and into ACEC, and Nuevo will merge with and
                       into ACPC, on the terms and conditions contained in that
                       certain Agreement of Merger in the form attached hereto
                       as Schedule M (the "Merger"), pursuant to which the
                       Companies shall be the surviving entities, and the
                       separate existences of Walter and Nuevo will cease upon
                       completion of the Merger.  This Agreement shall be
                       implemented by means of reverse subsidiary mergers
                       consistent with Schedule M, without affecting any of the
                       rights, remedies or obligations of any of the parties
                       hereto.

               (5)     Prior to the Closing, no Shares are or will be owned
                       either actually or constructively within the meaning of
                       section 318(a) of the Code by Guarantors or a member of

        written notice to the appropriate Purchaser on or before the second
        anniversary date of the date of Closing.  The foregoing is not intended
        to in any way limit the obligation of the Guarantors under Article 30,

                       OPIC of the Shares.

               (5)     The Government agrees that in the event OPIC proceeds
                       against the collateral under its loan, OPIC shall enjoy
                       all the rights and benefits of the Companies under the
                       Yombo Permit and that the Government shall communicate,
                       cooperate and otherwise deal with OPIC as it would have
                       dealt but for the assignment of the shares of the
                       Companies.

               (6)     The Government agrees that in the event of any asserted
                       post-closing default under the Yombo Permit which would
                       give the Government the possible right to terminate, the
                       Government agrees to give OPIC the right to cure.

               (7)     The Government agrees to confirm that immediately
                       following the transfer of the Companies' shares from
                       Seller to Purchasers:

                       (a)    The Companies and/or their Congo branches are

                       (b)    The Yombo Permit is in good standing and in full

               (8)     The Government agrees that the representations,
                       warranties, covenants and confirmations are for the
                       benefit of the Purchasers, the Companies and the Seller,
                       as well as for the benefit of OPIC.

               Investment Corporation ("OPIC") the political risk insurance and
               the financial guarantees for third party financing referenced in
               the commitment issued by OPIC to Purchasers on June 27, 1994.

               the Companies to maintain accounting records in United States
               dollars rather than CFAs shall have been resolved to the
               satisfaction of Purchasers as well as Seller.

                       including the purchase of warehouse inventory, and to
                       use its best efforts to preserve its business
                       organization intact and to conserve the good will and

               (8)     from the date hereof and to the extent that it does not
                       interfere unreasonably with normal business operations,

                       to allow Purchasers at their expense to make an audit or
                       otherwise satisfy itself of the accuracy of the
                       representations contained in this Agreement and that the
                       conditions contained in this Agreement have been

               (9)     other than in the ordinary course of business, not to
                       enter into any contract or agreement that Seller is

                       or amend in any material respect, or be in default in
                       any material respect under any contract or agreement
                       that Seller is required to disclose under Article 9.P;

               (10)    not to increase the indebtedness of, or incur any
                       obligation or liability, direct or indirect, for, either
                       of the Companies other than the incurrence of
                       liabilities in the ordinary course of business
                       consistent with past practices; provided, however, that

                       listed on Schedule I;

               indemnifying party, together with a statement of such
               information respecting any of such facts as it may have and a
               formal demand for indemnification.  The Indemnifying party shall
               not be obligated to indemnify the indemnified party with respect
               to any Claim if the indemnified party knowingly fails to notify
               the indemnifying party in sufficient time to permit the

               timely response thereto.

        B.     The indemnifying party shall be entitled at its cost and expense
               to contest and defend by all appropriate legal proceedings any
               Claim with respect to which they are called upon to indemnify
               the indemnified party; provided, that notice of the intention so
               to contest shall be delivered by the indemnifying party to
               indemnified party within 20 days after the date of receipt by
               the indemnifying party of notice by the indemnified party of the
               assertion of the Claim.  Any such contest may be conducted in
               the name and on behalf of the indemnifying party or the
               indemnified party as may be appropriate.  The indemnified party
               shall have the right but not the obligation to participate in
               such proceedings and to be represented by counsel of its own
               choosing at its sole cost and expense.

        C.     If requested by the indemnifying party, the indemnified party
               agrees to cooperate with the indemnifying party and its counsel
               in contesting any Claim that the indemnifying party elects to
               contest or, if appropriate, in making any counterclaim against
               the person asserting the Claim, or any cross-complaint against
               any person, and the indemnifying party will reimburse the
               indemnified party for any expenses it incurs by so cooperating.
               The indemnified party agrees to afford the indemnifying party
               and its counsel the opportunity to be present at, and to
               participate in, conferences with all persons asserting any Claim
               against the indemnified party or conferences with
               representatives of or counsel for such persons.

        D.     The indemnified party shall take no action which would prejudice
               the indemnifying party's defense of the matter giving rise to
               the Claim.

22.     Taxation

        A.     Tax Indemnification.  Except as otherwise provided in the Tax
               Agreement attached hereto as Schedule D, Purchasers agree to
               indemnify and pay Seller or its Affiliates for Taxes, if any,
               attributable to the Companies in the following manner:  (i) for
               the taxable periods which begin after the Effective Date,
               Purchasers shall indemnify Seller or its Affiliates for all
               Taxes, if any, attributable to the Companies for such periods,
               and (ii) for taxable periods which begin prior to the Effective
               Date but which end after the Effective Date (a "Straddle Taxable
               Period"), Purchasers shall indemnify Seller or its Affiliates
               for its allocable portion of the Taxes attributable to such
               period.  Except as otherwise provided in the Tax Agreement
               attached hereto as Schedule D, Seller agrees to indemnify and
               pay Purchasers or their Affiliates for all Taxes, if any,
               attributable to the Companies in the following manner:  (i) for
               taxable periods which end prior to the Effective Date, Seller
               agrees to indemnify Purchasers or their Affiliates for all Taxes
               attributable to such periods, and (ii) for a Straddle Taxable
               Period, Seller shall indemnify Purchasers and their Affiliates
               for its allocable portion of the Taxes attributable to such
               period.  Taxes for a Straddle Taxable Period shall be
               apportioned between two short periods.  Taxes attributable to
               the short period beginning on the opening date of the Straddle
               Taxable Period and ending at the close of the Effective Date
               shall be attributed to Seller, and Taxes attributable to the
               short period beginning on the first day after the Effective Date
               and ending on the last day of the Straddle Taxable Period shall
               be attributed to Purchasers and their Affiliates.  Taxes shall
               be apportioned between the two short periods by prorating such
               Taxes on a daily basis for the Straddle Taxable Period.
               Purchasers agree to execute and file and/or cause the Companies
               to execute and file such reasonable consents, elections and
               other documents and to take such other actions as may be
               reasonably necessary or appropriate to file, and to enable
               Seller or its Affiliates to file, all Tax returns for periods
               ending on or prior to the Effective Date to the extent that such
               Tax returns include the Companies.  Seller agrees to cooperate
               with Purchasers in the filing of all of the Tax returns for the
               Companies, the Purchasers, and their Affiliates and to execute
               and file such reasonable consents, elections and other documents
               and to take such other actions as may be reasonably necessary or
               appropriate to file such Tax returns.  In addition, Purchasers
               agree to be responsible for the payment of duties, if any, which
               are payable or may become due on the sale of the Shares of the
               Companies by Seller to Purchasers and indemnify Seller against
               any such liability, except as provided in Article 22.G.

        B.     Tax Refunds.  Purchasers agree to pay to Seller, or cause the
               Companies to pay to Seller, any and all Tax refunds received by
               or credited to the Companies after the Effective Date
               attributable to periods of the Companies' corporate existence
               prior to the Effective Date, and to pay such Tax refunds to
               Seller within ten (10)





                                       34
   39

               days after the Companies receives or is credited with such
               refunds.  All other Tax refunds after the Effective Date shall
               be for the account of Purchasers.

        C.     Rights to Contest Tax Claims Before the Payment of Tax.  Seller
               and Purchasers each agree to notify the other promptly in the
               event that in respect of the Companies (i) an examination of any
               Tax return is commenced, (ii) a deficiency assessment or other
               claim is made or asserted by the United States Internal Revenue
               Service, the Congolese Taxing Authority or any other Taxing
               authority.  In the event Seller is solely responsible for paying
               the Taxes described in this Article 22 or required to pay
               Purchasers the amount of such Taxes under any of the terms of
               this Agreement, Purchasers will permit Seller and will cause the
               Companies and/or its successor to permit Seller, at Seller's
               option and expense, to direct the Companies or Purchasers to
               take whatever actions are reasonably necessary in Seller's
               judgment to contest and defend any issues which may result in a
               claim for such Taxes prior to the payment of such Taxes and
               prior to the payment of the amount of such Taxes to Purchasers.
               In the event Purchasers and/or the Companies are responsible for
               paying Taxes described in this Article 22 or required to pay
               Seller the amount of such Taxes under any of the terms of this
               Agreement, Seller will permit Purchasers at Purchasers' option
               and expense, to direct Seller to take whatever actions are
               reasonably necessary in Purchasers' judgment to contest and
               defend any issues which may result in a claim for such Taxes
               prior to the payment of such Taxes and prior to the payment of
               the amount of such Taxes to Seller.  In the event of a claim by
               any Taxing authority which will adversely affect both Seller,
               Purchasers and/or the Companies by the liability to pay Taxes
               and by payments under the terms of this Agreement or, if the
               liability under such claim cannot be readily ascertained, Seller
               and Purchasers agree to cooperate fully with each other, each
               bearing its own expenses, to take whatever action is necessary
               to contest and defend or to direct the Companies to contest and
               defend any issue which may result in a claim for Taxes or a
               payment under the terms of this Agreement prior to the payment
               of such Taxes and prior to the payment of the amount of such
               Taxes to Purchasers or Seller.

        D.     Right to Litigate for Tax Refunds.  If a Tax has been paid to
               any Taxing authority and, as a result of the payment of such
               Tax, either Seller or Purchasers incurs a Unity to make payment
               to the other because of the payment of such Tax, provisions
               similar to Article 22.B above shall apply to enable the party or
               parties bearing the burden of the Tax liability to cause the
               appropriate party to take whatever action is necessary to claim,
               pursue or litigate with respect to a refund of such Tax.  If the
               entire burden of an increased Tax liability has been borne by
               Seller or by Purchasers, the right to litigate for or otherwise
               claim Tax refunds shall be assigned, to the extent it is legally
               permissible to do so, to the party bearing such economic burden.
               If any refunds or settlement amounts shall be delivered to the
               party who did not bear the burden of the Tax liability, such
               party shall assign such amounts to the party who bore the burden
               of the Tax liability.





                                       35
   40

               In the event both Seller and Purchasers jointly bear the
               economic burden of the payment of any Tax described in this
               Article 22.D, Seller and Purchasers agree to cooperate fully
               with each other, each bearing its own expenses, to cause the
               appropriate party to litigate the claim for Tax refund and to
               share the proceeds of any refund or settlement in proportion to
               the economic burden previously borne.

        E.     Tax Returns.  Seller shall be responsible for the preparation
               and filing of all Tax Returns of the Companies for taxable
               periods ending on or before the Closing Date.  Purchasers shall
               be responsible for the preparation and filing of all other Tax
               returns of the Companies for taxable periods ending after the
               Closing Date.

               Purchasers shall execute and file and/or cause the Companies to
               execute and file such reasonable consents, elections and other
               documents and to take such other actions as may be reasonably
               necessary or appropriate to file, and to enable Seller or its
               Affiliates to file any Tax returns for which the Seller is
               responsible.  Seller shall execute and file and/or cause its
               Affiliates to execute and file such reasonable consents,
               elections, and other documents and to take such other actions as
               may be reasonably necessary or appropriate to file, and to
               enable Purchasers, the Companies, or their Affiliates to file
               any Tax returns for which the Purchasers are responsible.

        F.     Payment.  All Taxes shall be paid by the party which is legally
               responsible therefor.

               Upon payment of any Taxes with respect to which a party is
               entitled to receive indemnification hereunder, such party shall
               submit an invoice to the indemnifying party stating that such
               Taxes have been paid and providing in appropriate detail the
               particulars relating thereto.  The indemnifying party shall
               remit payment for such Taxes promptly upon receipt of such
               invoice.

        G.     Transfer Taxes.  Seller will pay any United States sales, use,
               transfer, or documentary Taxes and recording and filing fees
               applicable to the transfer of the Shares to Purchasers at
               Closing.

        H.     Election Under Section 338(h)(10).  Purchasers shall make an
               election under section 338(g) of the Code with respect to the
               Companies.  Purchasers and Seller shall make a timely and
               effective election under section 338(h)(10) of the Code with
               respect to Purchasers' purchase of the Shares.  Purchasers and
               Seller shall cooperate fully with each other in the making of
               such election, and Seller's parent, Seller, Purchasers' parents,
               and Purchasers further agree that they will not take, or cause
               to be taken, any action in connection with the filing of any
               Return of the Companies or otherwise which would be inconsistent
               with or prejudice such elections.  In particular, and not by way
               of limitation, Purchasers shall deliver to Seller all
               information to enable Seller to prepare Form 8023 and all
               attachments





                                       36
   41

               required to be filed therewith (the "Form"), including the
               schedule of required data (as provided in Treasury Regulation
               Section 1.338-IT(e)(1) and any other schedules or data required
               to be attached to the Form.  At Closing, the Form shall be duly
               executed by an authorized person for each Party, and duly and
               timely filed by the Seller on behalf of the Purchasers and the
               Seller (as prescribed by Treasury Regulation Section
               1.338(h)10-1T).  The allocation of purchase price among the
               assets of the Companies shall be made in accordance with section
               338 of the Code and the Treasury Regulations promulgated
               thereunder and shall be mutually agreed to by the parties.

        I.     Termination of Tax Sharing Agreement

               The Companies' obligations under any tax sharing or tax
               allocation agreement shall be extinguished as of the Closing
               Date and such agreement shall be null and void as to the
               Companies after the Closing Date.

23.     Right of First Refusal

        Guarantors shall, prior to any sale, exchange, transfer, contribution,
        reorganization, distribution, actual or constructive liquidation,
        dissolution, lease, farmout, or other disposition of a Company or any
        of the Shares that would have the effect of causing a Company to cease
        being a member of its Consolidated Group or any of the assets of a
        Company or any Separate Unit thereof (other than sales of hydrocarbons
        or surplus materials or equipment in the ordinary course of business),
        notify Seller in writing of the terms and conditions of the proposed
        sale, exchange, transfer, contribution, disposition, reorganization,
        actual or constructive liquidation, dissolution, lease, farmout, or
        other disposition and Seller shall then have thirty (30) days to elect
        to purchase such Shares or assets on such notified terms.

24.     Termination

        A.     This Agreement may be terminated at any time:

               (1)     prior to Closing by the written agreement of Seller and
                       Purchasers;

               (2)     prior to Closing by Seller or Purchasers, by notice
                       thereof to the other, if the purchase and sale of the
                       Shares contemplated hereby shall not have been
                       consummated by September 15, 1994, or December 13, 1994,
                       if this Agreement has been extended pursuant to Article
                       8, or such other date, if any, as Seller and Purchasers
                       shall agree in writing, subject to the provisions of
                       Article 5.

        In the event of the termination of this Agreement by either party as
        provided hereunder, none of the parties shall have any liability
        hereunder of any nature whatsoever to the





                                       37
   42

        other, including any liability for damages; provided that if such
        termination shall result from the willful failure of one party to
        fulfill a condition to the performance of the other party hereto or to
        perform a covenant of this Agreement or from a willful
        misrepresentation by either party, such party shall be fully liable for
        any and all actual damages sustained or incurred by the other party,
        but shall not be liable for indirect, incidental or consequential
        damages, including without limitation, loss of profit or business
        interruption.

25.     Survival

29.     Governing Law and Dispute Resolution

        A.     This Agreement shall be governed by the laws of Illinois
               excluding any choice of law provisions which would require the
               application of the law of any other jurisdiction.

        B.     Any action, dispute, claim or controversy of any kind now
               existing or hereafter arising between any of the parties hereto
               in any way arising out of, pertaining to or in connection with
               this Agreement (a "Dispute") shall be resolved by binding
               arbitration in accordance with the terms hereof.  Any party may,
               by summary proceedings, bring an action in court to compel
               arbitration of any Dispute.

        C.     Any arbitration shall be administered by the American
               Arbitration Association (the "AAA") in accordance with the terms
               of this Article 30, the Commercial Arbitration Rules of the AAA,
               and, to the maximum extent applicable, the Federal Arbitration
               Act.  Judgment on any award rendered by an arbitrator may be
               entered in any court having jurisdiction.

        D.     Any arbitration shall be conducted before one arbitrator.  The
               arbitrator shall be a licensed practicing attorney who is
               knowledgeable in the subject matter of the Dispute selected by
               agreement between the parties hereto.  If the parties cannot
               agree on an arbitrator within 30 days after the request for an
               arbitration, then any party may request the AAA to select an
               arbitrator.  The arbitrator may engage engineers, accountants or
               other consultants that the arbitrator deems necessary to render
               a conclusion in the arbitration proceeding.

        E.     To the maximum extent practicable, an arbitration proceeding
               hereunder shall be concluded within 180 days of the filing of
               the Dispute with the AAA.  Arbitration proceedings shall be
               conducted in Houston, Texas.  Arbitrators shall be empowered to
               impose sanctions and to take such other actions as the
               arbitrators deem necessary to the same extent a judge could
               impose sanctions or take such other actions pursuant to the
               Federal Rules of Civil Procedure and applicable law.  At the
               conclusion of any arbitration proceeding, the arbitrator shall
               make specific written findings of fact and conclusions of law.
               The arbitrator shall have the power to award recovery of all
               costs and fees to the prevailing party.  Each party agrees to
               keep all Disputes and arbitration proceedings strictly
               confidential except for disclosure of information required by
               applicable law.

        F.     All fees of the arbitrator and any engineer, accountant or other
               consultant engaged by the arbitrator, shall be paid by Seller,
               on the one hand, and the Purchasers, on the other hand, equally
               unless otherwise awarded by the arbitrator.

               intent of this Agreement.

        B.     The Guarantors, jointly and severally, unconditionally guarantee
               as if each of them were the primary obligor, the punctual
               payment and performance of the Purchasers' obligations under

        remaining provisions hereof or affecting the validity or enforceability
        of such provision in any other jurisdiction.

33.     Execution in Counterparts

        This Agreement may be executed in any number of counterparts and by
        different parties hereto in separate counterparts, each of which when
        so executed and delivered shall be deemed to be an original and all of
        which taken together shall constitute but one and the same instrument.

34.     Entire Agreement

        This Agreement, including the Schedules, represents the entire
        understanding of the parties, and supersedes and replaces the letter of
        intent, dated December 2, 1993, as amended, and all other prior
        agreements, contracts, arrangements and understandings between the
        parties concerning the subject matter hereof.  There are no other
        terms, conditions, representations or warranties, express or implied,
        written or oral, except as set forth herein.  No amendments,
        modifications or additions hereto shall be binding unless executed in
        writing by Purchasers and Seller.

        law or regulation, the Convention, JOA, or this Agreement, the parties
        agree to keep confidential this Agreement and the terms and provisions
        hereof and not to disclose them to any third party without the prior
        written consent of the parties hereto, provided that after the date of
        Closing the parties hereto jointly shall issue a public announcement of
        the sale and purchase of the Shares.

37.     Restricted Transactions

        During the period beginning on the date hereof and ending on the
