Seller will deliver to Purchasers certificates representing the Shares, together with stock powers duly endorsed by Seller, so that the Shares may be duly registered in Purchasers' name upon receipt by Seller of confirmation that the consideration required pursuant to Article 3.A hereof has been received. Each purchase shall be accomplished by a reverse subsidiary merger as described in Article 11.D(4). 3. Purchase Price Upon the terms and subject to the conditions of this Agreement, Purchasers will purchase the Shares for the purchase price ("Purchase Price") of thirty one million five hundred 3 8 thousand United States ("U.S.") Dollars ($31,500,000), without prejudice to the Production Payment pursuant to Article 4, as follows: A. Purchasers will deliver at the Closing: (1) the sum of twenty one million five hundred thousand U.S. Dollars (U.S. $21,500,000) to the bank designated by Seller in Article 8.A hereof, by transfer in immediately available U.S. Dollars; plus (2) a Promissory Note in the amount of ten million U.S. Dollars ($10,000,000), subject to increase in accordance with Article 3.B below, in the form attached hereto as Schedule A, which Promissory Note shall be subordinate to the Overseas Private Investment Corporation ("OPIC") financing guarantee on terms acceptable to OPIC and Seller, together with a joint and several guaranty of payment from each of the Guarantors and an unconditional and irrevocable letter of credit in the form attached hereto as Schedule A securing payment of the Promissory Note, which letter of credit shall equal thirty percent (30%) of the principal amount of the Promissory Note after giving effect to the initial payment of principal contemplated in Article 3.B. B. At Closing, there shall be a calculation of a Balancing Payment. The Balancing Payment shall be the net sum of all amounts described in this Article 3.B (without duplication). If the Balancing Payment is positive, the principal amount of the Promissory Note shall be increased by such amount. If the Balancing Payment is negative, an initial payment of principal shall be deemed made under the Promissory Note at Closing in the amount of the Balancing Payment. If the Balancing Payment is negative and is in excess of the principal amount of the Promissory Note, the Promissory Note shall be deemed to have been paid in full and the excess amount shall be paid in cash by 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 12 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 be automatically extended at the request of Seller for ninety (90) days. 10 15 A. The following transactions shall take place at Closing: (1) Purchasers shall pay the cash portion of the Purchase Price specified in Article 3.A to Seller's account number 910-1-409-887 at the Chase Manhattan Bank, New York, New York.

Each Party shall bear and pay the expenses incurred by it in connection with the Closing. C. On or before Closing the Purchasers shall deliver to the Seller a copy, certified as a true copy and in full force and effect by a Director, Secretary or Assistant Secretary of a resolution of the Board of Directors of the Purchasers approving the purchase of the Shares on the terms of this Agreement and the execution on behalf of the Purchasers of all other documents contemplated hereby. D. The Parties shall execute all such other documents and do all acts and things as may be reasonably required in order to effect the sale and purchase of the Shares and otherwise carry out the intent of this Agreement. 11 16 9.
