AND THE INSTITUTIONS NAMED IN THE CREDIT AGREEMENT AS BANKS AND BANK ONE, OKLAHOMA, N.A., AS AGENT THIS FIRST AMENDMENT TO CREDIT AGREEMENT ("Amendment"), made and entered into this 10th day of February, 1999, by and among CONTINENTAL RESOURCES, INC., an Oklahoma corporation (individually, "Resources") and CONTINENTAL GAS, INC., an Oklahoma corporation (individually, "Gas") (Resources and Gas are herein- after collectively referred to as "Borrowers" and individually as a "Borrower"), andBANK ONE, OKLAHOMA, N.A., a national banking association ("Bank One- Oklahoma"), and each of the financial institutions which is a party hereto (as evidenced by the signature pages to this Amendment) or which may from time to time become a party hereto pursuant to the provisions of Section 28 of the Credit Agreement or any successor or assignee thereof (hereinafter collectively referred to as "Banks", and individually a "Bank") and Bank One-Oklahoma, as Agent (the "Agent") . W I T N E S S E T H: WHEREAS, on May 14, 1998 Borrowers, Banks and Agent entered into that certain Credit Agreement (the "Agreement") whereby Banks provided Borrower with a revolving line of credit in an amount which could not exceed $175,000,000.00 as evidenced by the Note subject to a Borrowing Base. WHEREAS, the obligations described in the Agreement are secured by, among other things not specifically set forth herein, certain Oil and Gas Proper- ties and other Collateral; and WHEREAS, all capitalized terms not otherwise defined herein shall have those meanings assigned to such terms in the Agreement; WHEREAS, Borrower, Banks and Agent desire to amend the Agreement for the first time in order to, among other things not specifically set forth in this recital, amend the dates for reporting semiannual reserve information and for redeterminations of the Borrowing Base. NOW THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Borrower, Banks and Agent hereby agree to amend the agreement as follows: CHANGES TO THE AGREEMENT 1. Section 7 of the Agreement, Borrowing Base, at Subsection (b), Subsequent Determinations of Borrowing Base, is hereby amended and restated in its entirety as follows: (b) Subsequent Determinations of Borrowing Base. Subsequent determinations of the Borrowing Base shall be made by the Banks at least semi- annually on March 1 and September 1 of each year beginning March 1, 1999 or as Unscheduled Redeterminations. In connection with, and as of, each determination of the Borrowing Base, the Banks shall also redetermine the Monthly Commitment Reduction. The Borrowers shall furnish to the Banks as soon as possible but in any event no later than February 1 of each year, beginning February 1, 1999, with an engineering report in form and substance satisfactory to the Agent prepared by an independent petroleum engineering acceptable to Agent covering the Oil and Gas Properties utilizing economic and pricing parameters used by Agent as established from time to time, together with such other information concerning the value of the Oil and Gas Properties as the Agent shall deem necessary to determine the value of the Oil and Gas Properties. By August 1 of each year, or within thirty (30) days after either (I) receipt of notice from Agent that the Banks require an Unscheduled Redetermination, or (ii) the Borrowers give notice to Agent of their desire to have an Unscheduled Redetermi- nation performed, the Borrowers shall furnish to the Banks an engineering report in form and substance satisfactory to Agent prepared by Borrowers' in-house engineering staff valuing the Oil and Gas Properties utilizing economic and pricing parameters used by the Agent as established from time to time, together with such other information, reports and data concerning the value of the Oil and Gas Properties as Agent shall deem reasonably necessary to determine the value of such Oil and Gas Properties. Agent shall by notice to the Borrowers no later than March 1 and September 1 of each year, or within a reasonable time thereafter (herein called the "Determination Date"), notify the Borrowers of the designation by the Banks of the new Borrowing Base and Monthly Commitment Reduction for the period beginning on such Determination Date and continuing until, but not including, the next Determination Date. If an Unscheduled Redetermination is made by the Banks, the Agent shall notify the Borrowers within a reasonable time after receipt of all requested information of the new Borrowing Base and Monthly Commitment Reduction, and such new Borrowing Base and Monthly Commitment Reduction shall continue until the next Determination Date. If the Borrowers do not furnish all such informa- tion, reports and data by any date specified in this Section 7(b), the Banks may nonetheless designate the Borrowing Base and Monthly Commitment Reduction at any amounts which the Banks in their discretion determine and may redesignate the Borrowing Base and Monthly Commitment Reduction from time to time thereafter until the Banks receive all such information, reports and data, whereupon the Banks shall designate a new Borrowing Base and Monthly Commitment Reduction as described above. Each Bank shall determine the amount of the Borrowing Base and Monthly Commitment Reduction based upon the loan collateral value which such Bank in its discretion (using such methodology, assumptions and discounts rates as such Bank customarily uses in assigning col- lateral value to oil and gas properties, oil and gas gathering systems, gas processing and plant operations) assigns to such Oil and Gas Properties and other Collateral of the Borrowers at the time in question and based upon such other credit factors consistently applied (including, without limitation, the assets, liabilities, cash flow, business, properties, prospects, management and ownership of the Borrowers and their affiliates) as such Bank customarily considers in evaluating similar oil and gas credits, but such Bank in its dis- cretion shall not be required to give any additional positive value to any Oil and Gas Property over the current economic and pricing parameters used by such Bank for such Determination Date which additional value is derived directly from a hedging, forward sale or swap agreement covering such Oil and Gas Pro- perty as of the date of such determination. All determinations or Unscheduled Redeterminations of the Borrowing Base and the Monthly Commitment Reduction require the approval of Majority Banks; provided, however, that notwithstanding anything to the contrary herein, the amount of the Borrowing Base may not be increased, nor may the Monthly Commitment Reduction be reduced, without the approval of all Banks. If the Banks cannot otherwise agree on the Borrowing Base or the Monthly Commitment Reduction, each Bank shall submit in writing to the Agent its proposed Borrowing Base nd Monthly Commitment Reduction and the Borrowing Base and Monthly Commitment Reduction shall be set on the basis of the weighted average of the Borrowing Bases and the weighted average of the Monthly Commitment Reductions proposed by the Banks. If at any time any of the Oil and Gas Properties are sold, the Borrowing Base then in effect shall automatically be reduced by a sum equal to the amount of prepayment required to be made pursuant to Section 12(r) hereof. The Borrowing Base shall be additionally reduced from time to time pursuant to the provisions of Sections 2(e) and 2(f) hereof. It is expressly understood that the Banks have no obli- gation to designate the Borrowing Base or the Monthly Commitment Reduction at any particular amounts, except in the exercise of their discretion, whether in relation to the Revolving Commitment or otherwise. Provided, however, that the Banks shall not have the obligation to designate a Borrowing Base in an amount in excess of the Revolving Commitment or its legal or internal lending limits. Upon the issuance of any public note issue permitted pursuant to Section 13(f)(iv) hereof, the Banks shall have the right to perform an Unscheduled Redetermination of the Borrowing Base. 2. Section 12 of the Agreement, Affirmative Covenants, at Subsection (a)(iii), Report on Properties, is hereby amended to replace the reference to the months of "April" and "October" with the months of "February" and "August" occurring in the second line of said Section 12(a)(iii). NOTICES AND WAIVERS. Borrower is hereby notified of the following occurrences and the Banks hereby provide the following waivers. 1. Borrowing Base. Pursuant to Section 2(e) of the Agreement, the Borrowers hereby voluntarily reduce the Borrowing Base from $75,000,000.00 to $25,000,000.00 until March 1, 1999. It is agreed by the Borrowers, the Banks and the Agent that this reduction shall be retroactively effective to the originally scheduled redetermination date of November 1, 1998. 2.
