W I T N E S S E T H: WHEREAS, Bank and Borrower entered into that certain Second Amended and Restated Loan Agreement dated December 22, 1997 (the "Loan Agreement"), pursuant to which Borrower obtained a credit facility in the amount of up to the lesser of the Borrowing Base (as defined in the Loan Agreement) or the Commitment (as defined in the Loan Agreement); and WHEREAS, Bank and Borrower entered into that certain First Amendment to Second Amended and Restated Loan Agreement dated May 19, 1998 (the "First Amendment") in order to modify certain terms of the Loan Agreement to, among other things, establish the current Borrowing Base and modify certain financial covenants; and WHEREAS, Bank and Borrower entered into that certain Second Amendment to Second Amended and Restated Loan Agreement dated July 8, 1998 (the "Second Amendment") in order to modify certain terms of the Loan Agreement to, among other things, further modify the Borrowing Base; and WHEREAS, Bank and Borrower now desire to further amend that Loan Agreement as herein set forth. NOW, THEREFORE, in consideration of the premises herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 1. Definitions. Except as otherwise provided, unless the context hereof indicates otherwise, all capitalized terms used herein shall have the same meaning as such capitalized terms are defined in the Loan Agreement. 2. Borrowing Base. Section 2.2(b) of the Loan Agreement is hereby deleted in its entirety and replaced with the following: "(b) After receipt of all of the information required by Section 2.2(a), Bank may redetermine the amount of the Borrowing Base in accordance with the customary practices of Bank for oil and gas loans to be effective as of April 1 and October 1 of such year. In connection with the initial Redetermination of the Borrowing Base as 1 2 set forth herein, Borrower agrees to pay to Bank an Engineering Fee in the amount of $2,500. Thereafter, upon each subsequent delivery to Bank of the information required by 2.2(a), Borrower shall pay to Bank an Engineering Fee in the amount of $2,500. Until the next determination of the amount of the Borrowing Base by Bank on or about October 1, 1998, the amount of the Borrowing Base shall be deemed to be $5,240,000. Until each new determination of Borrowing Base is made by Bank, the amount of the Borrowing Base shall be deemed to be the Borrowing Base last deemed or calculated, as the case may be. In addition to the foregoing, Bank or Borrower may initiate a redetermination of the Borrowing Base at any other time as it so elects, provided, however, that Borrower may initiate only two (2) such unscheduled redeterminations during any consecutive twelve (12) month period by specifying in writing to Bank the date on which Borrower will furnish the information required by Section 2.2(a) and the date on which it desires such redetermination to occur. Bank shall have at least forty-five (45) days after the delivery of the information required by Section 2.2(a) to make any unscheduled redetermination of the Borrowing Base requested by Borrower. Bank may, at any time and at its expense, initiate an unscheduled redetermination of the Borrowing Base by specifying in writing to Borrower the date by which Borrower is to furnish the information required by Section 2.2(a) (excluding the information required by Section 2.2(a)(i) and the projected date on which such redetermination is to occur. Failure of Borrower to timely furnish such information required by Section 2.2(a) shall not preclude Bank's right to redetermine the Borrowing Base based on information previously furnished to Bank. Bank shall promptly notify Borrower in writing of the new Borrowing Base. Any redetermination of the Borrowing Base shall not be effective until written notice is sent to Borrower." 3. Interest Rate. Section 2.4(a) of the Loan Agreement is hereby deleted in its entirety and the following substituted therefor: "(a) Each Prime Rate Advance shall bear interest on the unpaid principal amount thereof until payment in full at a rate equal to the sum of the Prime Rate plus one percent (1%) , but in no event to exceed the Highest Lawful Rate. Any change in the interest rate accruing on an Advance resulting from a change in the Prime Rate shall become effective as of the opening of business on the day on which such change in the Prime Rate shall occur. For the period from August 19, 1998 through September 30, 1998, Borrower may not elect to have any Advance accrue interest at a rate using LIBOR. Thereafter, and as long as no Event of Default or Potential Default has occurred or is continuing, each LIBOR Advance shall bear interest on the unpaid principal amount thereof until payment in full at the Effective LIBOR Rate, but in no event to exceed the Highest Lawful Rate." 2 3 4. Equity Offering. A new Section 6.34 is hereby added to the Loan Agreement as follows: "6.34 Equity Offering. On or before September 30, 1998, Borrower shall have completed the closing and funding of the issuance, in accordance with all applicable securities and other Laws, of an amount of the common stock of Borrower which results in net proceeds to Borrower (after deducting all costs and expenses associated therewith, including, without limitation, all underwriting fees, printing costs, placement fees and expenses, accountants, attorneys and other professional fees) of at least $3,000,000, upon terms and conditions which are approved, in advance, by Bank and provided that the net proceeds thereof shall be used by Borrower to redevelop, recomplete and workover any of the existing Oil and Gas Properties of Borrower which are part of the Collateral and for other general working capital purposes." 5.
