AMENDMENT TO OPTION AND PURCHASE AGREEMENT THIS AMENDMENT TO OPTION AND PURCHASE AGREEMENT (this "Amendment") is entered into as of this 11th day of August, 1998, by and between FORELAND CORPORATION, a Nevada corporation ("Foreland") on the one hand, and PETRO SOURCE CORPORATION, a Utah corporation ("Petro Source Corporation"), FORELAND REFINING CORPORATION, a Texas corporation ("Foreland Refining"), and PETROSOURCE TRANSPORTATION, a Utah corporation ("Petrosource Transportation"), on the other (Petro Source Corporation, Foreland Refining, and Petrosource Transportation are collectively referred to as "PSC"), based on the following: PREMISES A. Foreland, Petro Source Corporation, and Petrosource Transportation are parties to that certain Option and Purchase Agreement dated December 31, 1997 (the "Option and Purchase Agreement"). Foreland Refining is a successor, through merger, to Petro Source Refining Corporation, a Utah corporation ("Petro Source Refining"), which was also a party to the Option and Purchase Agreement. B. In May 1998, Foreland exercised its option to purchase the Business and Business Assets as defined in the Option and Purchase Agreement, and the parties are obligated to close that transaction. C. The parties desire to amend the Option and Purchase Agreement in order to modify certain provisions thereof to reflect changes and modifications that have been agreed to since the execution of the Option and Purchase Agreement, including the restructuring of the transaction as the acquisition of certain assets of Foreland Refining, including the stock of Petrosource Transportation, by a newly-formed, wholly-owned subsidiary of Foreland, Foreland Asset Corporation ("Foreland Asset"), followed by the acquisition by Foreland of Foreland Refining, rather than the sale of assets of Petro Source Refining and Petrosource Transportation to Foreland as originally contemplated by the Option and Purchase Agreement. D. The parties desire to ratify and reaffirm all of the terms and conditions of the Option and Purchase Agreement, except those provisions specifically modified by the terms of this Amendment. AGREEMENT NOW, THEREFORE, based on the foregoing premises, and in consideration of the mutual covenants and agreements hereinafter set forth and the mutual benefit to the parties to be derived herefrom, it is hereby agreed as follows: 1.

The Closing Statement shall contain and shall have attached thereto such supporting documentation and other data as is reasonably necessary to provide a basis for the Estimated Adjustments to Base Price shown therein.

(iii) The net amount of the Estimated Adjustments to Base Price shall be paid by the delivery by Foreland to Petro Source Corporation at the Closing of 763,602 shares of Foreland Stock (the "Closing Shares"), which shall be registered in the name of Petro Source Corporation and held and disposed of in accordance with the terms and conditions of subparagraph (e) of this section 3.05A. (d) Payments and Deliveries. Prior to 11:00 a.m. Houston time on the Closing Date, Foreland shall (i) pay an amount equal to the Base Price for the account of Petro Source Corporation by wire transfer of funds to Petro Source Corporation's designated bank account, and (ii) deliver to Petro Source Corporation one or more certificates for the Original Shares and the Closing Shares.. Petro Source Corporation shall deliver or cause to be delivered the Releases, as defined in Section 6.03A, together with all conveyances, instruments, and documents to be delivered by or on behalf of Petro Source Corporation at Closing. (e) Delivery and Sale of Original Shares and Closing Shares. The Original Shares and the Closing Shares shall be issued, held, and disposed of as follows: (i) At the earliest practicable date, but in any event by the earlier of the date that is (A) 10 days after the filing by Foreland of a report containing historical and pro forma combined financial information respecting the purchased Business and Business Assets pursuant to section 13 of the Securities Exchange Act of 1934, or (B) 75 days after the Closing Date, Foreland shall file, at its sole cost, a Registration Statement on such form as Foreland may select under the Securities Act covering the resale of the Closing Shares and the Original Shares, by and for the account of Petro Source Corporation, which shall be named as a selling shareholder in the Registration Statement, all as more particularly set forth in Article IX hereof. Foreland shall utilize its best efforts to obtain the effectiveness of the Registration Statement at the earliest practicable date and to maintain its effectiveness until June 30, 1999. In the event that all of the Closing Shares are not sold by Petro Source Corporation under the Registration Statement on or before December 31, 1998, Foreland shall pay interest to Petro Source Corporation in cash equal to 5.0% per annum multiplied by the difference between (i) the Estimated Adjustments to Base Price less (ii) the net proceeds realized by Petro Source Corporation from the sale of such Closing Shares. Such amounts shall be paid by Foreland to Petro Source Corporation on the last day of each month beginning with the last day of January 1999. The amount described in the preceding sentence shall be paid in addition to the interest Petro Source Corporation is entitled to receive pursuant to the following paragraph. (ii) Petro Source Corporation may cause to be sold, at any time and from time-to-time and in accordance with the Registration Statement, that number of Closing Shares that yields proceeds, net of brokerage and other usual and customary transaction costs, the Estimated Adjustments to Base Price, plus simple interest on the unpaid balance from the Closing Date to the date such net proceeds from such sale are available to the account of Petro Source Corporation at the rate of 10% per annum (the "Realizable Amount"), provided, however, that Petro Source Corporation shall not sell or place an order to sell in the Nasdaq SmallCap Market that number of Closing Shares that would yield net proceeds of more than $400,000 in any consecutive 30 day period without Foreland's prior consent. There are no restrictions on the sale of the Original Shares of Foreland Stock delivered to Petro Source Corporation at Closing, other than in accordance with the Registration Statement. (iii) If the net proceeds from the sale of Closing Shares are less than the Realizable Amount, Petro Source Corporation may demand that Foreland pay such deficiency, in which case Foreland shall, within five days after such demand, at its option, either pay such amount in cash in immediately available funds or deliver to Petro Source Corporation such additional shares of Common Stock as Foreland estimates will yield net proceeds in the amount sufficient for Petro Source Corporation to realize in cash the Realizable Amount (the "Additional Shares"). Should the proceeds from the Additional Shares prove to be insufficient for Petro Source Corporation to realize in cash the Realizable Amount, Petro Source Corporation may demand that Foreland pay such deficiency, in which case Foreland shall, within five days after such demand, pay Petro Source Corporation such deficiency in cash. (iv) If any Closing Shares or Additional Shares remain unsold after the receipt by Petro Source Corporation of the Realizable Amount, such shares shall be returned to Foreland for cancellation. If Closing Shares or Additional Shares have been sold for net proceeds in excess of the Realizable Amount, such excess proceeds shall also be delivered to Foreland. Petro Source Corporation agrees to provide Foreland with access to the records concerning the sales of Closing Shares and Additional Shares in order to permit Foreland to verify the amount realized by Petro Source Corporation on such sales. 8.

Foreland and its representatives shall be provided access to all of Petro Source Corporation's books, records, computer runs, and other documents containing information on which the Adjustment Statement is based for the purpose of conducting an audit thereof or such other review as Foreland may deem appropriate. (b) Final Determination of Adjustments. The Adjustment Statement shall become final and binding on Petro Source Corporation and Foreland on the twentieth business day following the date the Adjustment Statement is received by Foreland, unless prior to such twentieth business day Foreland shall deliver to Petro Source Corporation notice of its disagreement with the contents of the Adjustment Statement, together with proposed changes thereto. If Foreland has delivered a notice of disagreement, then the Adjustment Statement will become final and binding upon written agreement between Foreland and Petro Source Corporation resolving all disagreements of Foreland. If the Adjustment Statement has not become final and binding by the thirtieth business day following its receipt by Foreland, then the Adjustment Statement shall be submitted to binding arbitration in accordance with the commercial rules of the American Arbitration Association, except that only one arbitrator shall be used. The fees and expenses of such arbitration shall be borne 50% by Petro Source Corporation and 50% by Foreland. The determination of the Adjustment Statement by such arbitration shall be final and binding upon Foreland and Petro Source Corporation. (c) Adjustment Payments. On the day the Adjustment Statement becomes final and binding, Foreland and Petro Source Corporation shall make the following payments: (i) If the mathematical sum of the actual amounts of the items specified in subsections 3.05(a) through (h) as shown in the final and binding Adjustment Statement, is less than the mathematical sum of the items to specified in subsections 3.05(a) through (h) in the Closing Statement, then Petro Source Corporation shall pay Foreland an amount equal to such deficiency. (ii) If the mathematical sum of the actual amounts of the items specified in subsections 3.05(a) through (h) as shown in the final and binding Adjustment Statement, exceeds the mathematical sum of the items to specified in subsections 3.05(a) through (h) in the Closing Statement, then Foreland shall pay Petro Source Corporation an amount equal to such excess. Any payments required by this Section 3.06A shall be by wire transfer to the account designated by the party to receive such payment. 9.
