         in effect until the next redetermination thereof resulting from the
         making of an Advance hereunder or the repayment of any principal on the
         Notes.

                  "LENDERS" means each signatory hereto other than Borrower,

         Note.

         (f) The definition of "Maximum Loan Amount" in Section 1.1 of the
Original Agreement is hereby amended in its entirety to read as follows:

                  "MAXIMUM LOAN AMOUNT" has the following meaning:

                  30, 1999, the Maximum Loan Amount means the amount of
                  $320,000,000.

                           (b) From May 1, 1999 until and including December 31,
                  1999, the Maximum Loan Amount means the amount of
                  $300,000,000.

                  Amount means the amount of $275,000,000.

                  Notwithstanding the foregoing, in the event Borrower issues
                  preferred or common shares of capital stock for an aggregate
                  price of not less than $80,000,000 on or before April 30,
                  1999, the Maximum Loan Amount shall be $320,000,000 until
                  Lenders have no further obligations to make Advances hereunder
                  and the Obligations have been paid in full.

         (g) The definition of "Percentage Share" in Section 1.1 of the Original
Agreement is hereby amended in its entirety to read as follows:

                  "PERCENTAGE SHARE" means, with respect to any Lender (a) when
         used in Sections 2.1, 2.5 or 2.A.2(b), in any Request for Advance or
         when no Loans are outstanding hereunder, the percentage set forth
         opposite such Lender's name on the signature pages of this Agreement or
         as set forth on any amendment, assignment or other instrument that
         expressly designates the Percentage Share of a Lender that is a party
         thereto, and (b) when used otherwise, the percentage equal to the
         unpaid principal balance of such Lender's Loan at the time in question
         divided by the aggregate unpaid principal balance of all Loans at such
         time.

         Section 2.2 COMMITMENT AND FACILITY FEES. The first sentence of Section
2.5 of the Original Agreement is hereby amended in its entirety to read as
follows:

                  "In consideration of each Lender's commitment to make Advances
                  up to the amount of the Borrowing Base in effect from time to
                  time, Borrower will pay to Agent for the account of each
                  Lender a commitment fee determined on a daily basis by
                  applying the Commitment Fee Margin in effect at such time to
                  such Lender's Percentage Share of the unused portion of the
                  Borrowing Base on each day during

                                        4


<PAGE>   5
                  the Commitment Period, determined for each such day by
                  deducting from the Borrowing Base the aggregate unpaid
                  principal balance of the Loans and outstanding LC Obligations
                  at the end of such day."

         Section 2.3 CURRENT RATIO. Section 5.2(k) of the Original Agreement is
hereby deleted in its entirety and paragraphs (l), (m), and (n) of such Section
are hereby amended by designating such paragraphs as "(k), (l), and (m),"
respectively.

                                  ARTICLE III.

                        REDETERMINATION OF BORROWING BASE
                         AND WAIVER OF EXISTING DEFAULT

         Section 3.1 BORROWING BASE REDETERMINATION. Contemporaneously with the
execution and delivery of this Amendment by the parties hereto, the Borrowing
Base is hereby redetermined to be $320,000,000, such redetermination to remain
in effect until the next Determination Date.

         Section 3.1 WAIVER OF CURRENT RATIO DEFAULT. Section 5.2(k) of the
Original Agreement provides that the ratio of Borrower's Consolidated Current
Assets to Borrower's Consolidated Current Liabilities (the "CURRENT RATIO") will
never be less than 1.0 to 1.0. Borrower has informed Agent that at September 30,
1998 Borrower's Current Ratio was not in compliance with Section 5.2(k) of the
Original Agreement. Such noncompliance constitutes a Default under the Original
Agreement (herein called the "SUBJECT DEFAULT"), and Borrower has requested that
Lenders waive the Subject Default. Based upon the representations and warranties
set forth in Section 5.1 of this Amendment, Lenders hereby waive the Subject
Default. The waiver provided herein shall be effective only in this specific
instance and for the purpose described herein and shall in no event be construed
to be a waiver of any other Default or Event of Default now existing or
hereafter arising under, or any other violation by Borrower of, the Credit
Agreement or any other Loan Document or any other waiver of any of Agent's or
any Lender's rights or remedies under the Credit Agreement or any other Loan
Document.

                                   ARTICLE IV.

                           CONDITIONS OF EFFECTIVENESS

         Section 4.1 EFFECTIVE DATE. This Amendment shall become effective as of

         respects at and as of the time of the effectiveness hereof.

                  (b) Borrower is duly authorized to execute and deliver this
         Amendment and is and will continue to be duly authorized to borrow
         monies and to perform its obligations under the Credit Agreement.
         Borrower has duly taken all corporate action necessary to authorize the
         execution and delivery of this Amendment.

                  (c) The execution and delivery by Borrower of this Amendment
         and the performance by Borrower of its obligations hereunder do not and
         will not conflict with any provision of law, statute, rule or
         regulation or of the certificate of incorporation and bylaws of
         Borrower, or of any material agreement, judgment, license, order or
         permit applicable to or binding upon Borrower, or result in the
         creation of any lien, charge or encumbrance upon any assets or

                  (d) When duly executed and delivered, each of this Amendment
         and the Credit Agreement will be a legal and binding obligation of
         Borrower, enforceable in accordance with its terms, except as limited

         relating to the enforcement of creditors' rights and by equitable
         principles of general application.

                  (e) The audited Consolidated financial statements of Borrower
         dated as of December 31, 1997 and the unaudited financial statements of
         Borrower dated as of June 30, 1998 fairly present the Consolidated
         financial position at such dates and the Consolidated statement of
         operations and the changes in Consolidated financial position for the
         periods ending on such dates for Borrower. Copies of such financial
         statements have heretofore been delivered to each Lender. Since June
         30, 1998, no material adverse change has occurred in the financial
         condition or businesses of Borrower except for changes in oil and gas
         prices that affect the industry in which Borrower operates.
