      outstanding principal amount of the Revolving Credit Loans to exceed the
      greater of (i) $200 million and (ii) the previous highest aggregate

      the Administrative Agent for the ratable benefit of the Lenders (based on
      each Lender's Commitment Percentage) a fee equal to the product obtained

      principal amount of the Revolving Credit Loans on such Borrowing Date

      Borrowing Date) exceeds the Base Amount."

      4. AMENDMENTS TO SUBSECTION 4.9. Subsection 4.9 of the Credit Agreement is

            "4.9 COMPUTATION OF BORROWING BASE. (a) BORROWING BASE. (i) The

      principal amount (subject to the aggregate amount of the Revolving Credit
      Commitments) of Loans and Letter of Credit Outstandings that the Lenders
      will allow to remain outstanding during the Commitment Period. Until the
      March '99 Redetermination, the Borrowing Base will be based upon the value
      of certain Proved Reserves attributable to the Oil and Gas Properties of
      the Borrower and its Subsidiaries and other assets of the Borrower and its
      Subsidiaries acceptable to the Administrative Agent in its sole
      discretion, and will be determined by the


                                                                               5

      Administrative Agent in accordance with paragraph (d) of this subsection
      4.9, subject to approval by the Supermajority Lenders (or, with respect to
      the March '99 Redetermination, all of the Lenders). Until the Commitments
      are no longer in effect, all Letters of Credit have terminated and all of
      the Loans and all other obligations under this Agreement are paid in full,
      this Agreement shall be subject to the then effective Borrowing Base.

            (b) RESERVE REPORTS. Prior to March 1 and September 1 of each year,
      the Borrower shall, at its own expense, furnish to the Administrative
      Agent and to each Lender Reserve Reports, which Reserve Reports shall be
      dated as of the immediately preceding December 31 (in the case of Reserve
      Reports due on March 1) and June 30 (in the case of Reserve Reports due on
      September 1), and shall set forth, among other things, (i) the Oil and Gas
      Properties, then owned by the Borrower and its Subsidiaries, (ii) the
      Proved Reserves attributable to such Oil and Gas Properties and (iii) a
      projection of the rate of production and net income of the Proved Reserves
      as of the date of such Reserve Report, all in accordance with the
      guidelines published by the Securities and Exchange Commission and such
      assumptions as the Administrative Agent shall provide. Concurrently with
      the delivery of the Reserve Reports, the Borrower shall furnish to the
      Administrative Agent and to each Lender a certificate of a Responsible
      Officer showing any additions to or deletions from the Oil and Gas
      Properties listed in the Reserve Report, which additions or deletions were
      made by the Borrower and its Subsidiaries since the date of the previous
      Reserve Report.

            (c) REDETERMINATIONS OF THE BORROWING BASE. The Borrowing Base shall
      be redetermined (i) after receipt by the Administrative Agent of each
      scheduled Reserve Report, commencing with the Reserve Report prepared as
      of December 31, 1998, (ii) upon the delivery of a Lender Redetermination
      Notice to the Borrower and (iii) upon the delivery of a Borrower
      Redetermination Notice to the Administrative Agent, all as provided in
      this subsection 4.9. Within 15 days after the delivery of a Borrower
      Redetermination Notice or a Lender Redetermination Notice, the Borrower
      shall furnish to the Administrative Agent and to each Lender a Reserve
      Report as of the most recent practicable date. If the Borrower fails to
      deliver a Reserve Report within the time period provided for in the
      preceding sentence, then the Administrative Agent shall have the right to
      rely on the last Reserve Report previously delivered by the Borrower with
      any such adjustments and taking into account any additional information as
      the Administrative Agent may deem appropriate, in its sole discretion. On
      or before the date which is 30 days after receipt (i) of a scheduled
      semi-annual Reserve Report or (ii) of a Reserve Report in connection with
      a Lender Redetermination Notice or a Borrower Redetermination Notice, the
      Administrative Agent shall redetermine the Borrowing Base in its sole
      discretion, and the Administrative Agent shall notify the Borrower and the
      Lenders of its redetermination of the Borrowing Base. Within 10 days after
      receipt from the Administrative Agent of the amount of the its
      redetermination of the Borrowing Base, each Lender shall notify the
      Administrative Agent stating whether or not such Lender agrees with that
      redetermination. Failure of any Lender to give such notice within such

                                                                               6

      period of time shall be deemed to constitute an acceptance of such
      redetermination. If the Supermajority Lenders (or, with respect to the
      March '99 Redetermination, all of the Lenders) agree with that
      redetermination, then the Administrative Agent promptly shall notify the
      Borrower of the Borrowing Base as so redetermined, whereupon that
      redetermined value shall automatically become effective (and shall remain
      effective until the Borrowing Base is again redetermined as provided in
      this subsection 4.9(c)). If the Supermajority Lenders (or, with respect to
      the March '99 Redetermination, all of the Lenders) have not approved or
      are not deemed to have approved the Borrowing Base within the 10 day
      period following their receipt of the proposed amount from the
      Administrative Agent, the Borrowing Base shall be set at the amount of the
      then current Borrowing Base and the Borrowing Base shall remain at such
      level until the Supermajority Lenders (or, with respect to the March '99
      Redetermination, all of the Lenders), utilizing the procedure outlined
      herein, agree on a new Borrowing Base. Each redetermination provided for
      by this subsection 4.9(c) shall be made in accordance with the provisions
      of subsection 4.9(d). It is the intention of the Borrower and the Lenders
      that the Borrowing Base be redetermined within 45 days after the
      furnishing of each Reserve Report, subject to the provisions of this
      paragraph (c).

            (d) CRITERIA. (i) All determinations and redeterminations by the
      Administrative Agent provided for in this subsection 4.9 (and any
      determinations and decisions by either or both of the Administrative Agent
      and the Supermajority Lenders (or, with respect to the March '99
      Redetermination, all of the Lenders) in connection therewith, including
      effecting any redetermination of the value of any component contained in a
      Reserve Report) shall be made by the Administrative Agent and the Lenders
      in their sole discretion and shall be made on a reasonable basis and in
      good faith based upon the application by the Administrative Agent and the
      Lenders of their respective normal oil and gas lending criteria as they
      exist at the time of determination.

            (ii) All redeterminations of the Borrowing Base referred to in this
      subsection 4.9 shall become effective immediately upon the delivery of
      notice by the Administrative
      Agent to the Borrower of the redetermination.

            (iii) Upon the issuance of any Subordinated Indebtedness, the
      Borrowing Base shall be redetermined in accordance with the procedures set
      forth in subsection 4.9 which would have applied had a Borrower
      Redetermination Notice or a Lender Redetermination Notice been delivered.

            (e) TITLE. Concurrently with the delivery to the Administrative
      Agent of each Reserve Report, the Administrative Agent may request that
      the Borrower furnish to the Administrative Agent reasonable evidence of
      the Borrower's title to the Oil and Gas Properties which have been
      developed or acquired by the Borrower subsequent to the Reserve Report
      immediately preceding such Reserve Report."

                                                                               7

      5. AMENDMENTS TO SECTION 4.10. Subsection 4.10 of the Credit Agreement is
hereby amended by deleting such subsection in its entirety and substituting in
lieu
thereof the following:

            "4.10 BORROWING BASE COMPLIANCE. If, upon any redetermination of the
      Borrowing Base pursuant to subsection 4.9(c) other than in connection with
      the issuance of Subordinated Indebtedness provided for in subsection
      8.2(f), the Aggregate Revolving Credit Exposure of the Lenders exceeds the
      Borrowing Base then in effect (any such excess, the "BORROWING BASE
      DEFICIENCY"), the Borrower shall prepay the Revolving Credit Loans and
      then to the extent necessary, cash collateralize the Letter of Credit
      Outstandings in an amount equal to at least 50% of the Borrowing Base
      Deficiency within 90 days after the effective date of the redetermination
      resulting in such Borrowing Base Deficiency, and within the next 90 days
      prepay the Revolving Credit Loans and then cash collateralize the Letter
      of Credit Outstandings in an amount equal to the balance of such Borrowing
      Base Deficiency in each case together with interest accrued to the date of
      such payment or prepayment and any amounts payable under subsection 4.14;
      PROVIDED that, if there exists a Borrowing Base Deficiency upon the March
      '99 Redetermination the Borrower shall within 30 days of the effectiveness
      of the March '99 Redetermination prepay the Revolving Credit Loans and
      then cash collateralize the Letter of Credit Outstandings (together with
      interest accrued to the date of such payment or prepayment and any amounts
      payable under subsection 4.14) in an amount equal to such Borrowing Base
      Deficiency. If at any other time there exists a Borrowing Base Deficiency
      (including as a result of a redetermination in connection with the
      incurrence of Subordinated Indebtedness provided for in subsection
      8.2(f)), the Borrower shall immediately prepay the Revolving Credit Loans
      and then to the extent necessary, cash collateralize the Letter of Credit
      Outstandings in an amount equal to 100% of such Borrowing Base Deficiency
      together with (i) interest accrued to the date of such payment or
      prepayment and (ii) any amounts payable under subsection 4.14.
      Notwithstanding the foregoing, the Borrower shall immediately apply 100%
      of the Net Proceeds of any Redetermination Event described in clauses (a),
      (b), (c) or (d) of the definition thereof to prepay outstanding Loans and
      then cash collateralize the Letter of Credit Outstandings. Prepayments and
      collateralization pursuant to this subsection 4.10 shall be made as set
      forth in subsection 4.5(c)."

      percentages of Proved Reserves consisting of proved developed producing
      reserves, proved developed non-producing reserves and proved undeveloped
      reserves; and"

                                                                               8

      7. AMENDMENTS TO SECTION 7.11. Subsection 7.11 of the Credit Agreement is

      Agent) and PROVIDED that, if upon redetermination of the Borrowing Base in
      connection with the March '99 Redetermination it is determined that there
      is no Borrowing Base Deficiency or if there is, such deficiency is cured
      within 30 days, the Liens created by such Mortgages shall be released if,
      at such time, (x) no Default or Event of Default has occurred and is
      continuing and (y) the December 31, 1998 Reserve Report is delivered by
      the Borrower to the Administrative Agent by March 1, 1999."

      8. AMENDMENT TO SECTION 7. Section 7 of the Credit Agreement is hereby
amended by adding after subsection 7.11 and before Section 8, the following:

            "7.12 ADDITIONAL COLLATERAL. (a) The Borrower shall take all action
      so that no later than December 11, 1998, the schedules of description of
      properties to be included with the Additional Mortgage are delivered in
      proper recordable form to the Administrative Agent, such that the
      Additional Mortgage (when recorded) together with the Existing Mortgage
      shall give the Lenders a first lien on Proved Reserves of the Borrower
      constituting at least 75% of the net present value of all the Proved
      Reserves of the Borrower and its Subsidiaries as reflected in the Reserve
      Report dated September 3, 1998, prepared by the Borrower and delivered to
      the Lenders. In addition, the Adminstrative Agent shall receive no later
      than December 11, 1998, a certificate from the Borrower satisfactory to
      the Administrative Agent as to the fact that the Additional Mortgage
      together with the Existing Mortgage shall give the Lenders when the
      Additional Mortgage is properly filed, a first lien on Proved Reserves of
      the Borrower constituting at least 75% of the net present value of all the
      Proved Reserves of the Borrower and its Subsidiaries as reflected in the
      foregoing Reserve Report.

            (b) The Borrower hereby directs the Administrative Agent to file and
      record the Additional Mortgage in all filing offices as the Administrative
      Agent deems appropriate upon the occurrence of any of the following events
      (and the Administrative Agent and the Lenders agree not to file or record
      the Additional Mortgage until the occurrence of any of the following
      events):


                                                                               9

            (i) the Borrower fails to deliver the certificate required by
      subsection 7.2(f) by January 15, 1999 or if the Borrower delivers such
      certificate, subsequent information is received by the Borrower or the
      Administrative Agent which demonstrates to the reasonable satisfaction of
      the Administrative Agent that the Borrower is not in compliance with
      subsection 8.1(d), (e), or (f); or

            (ii) if the Borrower fails to deliver the Reserve Report for
      December 31, 1998 to the Administrative Agent by March 1, 1999 or if upon
      redetermination of the Borrowing Base in connection with the March '99
      Redetermination it is determined that a Borrowing Base Deficiency exists
      and the Borrower fails to cure such deficiency within 30 days of the
      effective date of the March '99 Redetermination by prepaying the Revolving
      Credit Loans and/or cash collateralizing Letter of Credit Outstandings.

            (c) Upon the filing of the Additional Mortgage to the extent
      required under paragraph (b) above, the Borrower shall take all other
      action so that on such date the Administrative Agent on behalf of the
      Lender shall have a valid perfected first mortgage lien on Proved Reserves
      of the Borrower constituting at least 75% of the net present value of all
      the Proved Reserves of the Borrower and its Subsidiaries as reflected in
      the most recent Reserve Report and thereafter the Borrower shall take such
      action as is necessary so that the Administrative Agent on behalf of the
      Lenders continues to have a first mortgage lien on Proved Reserves of the
      Borrower constituting at least 75% of the net present value of the Proved
      Reserves of the Borrower and its Subsidiaries as reflected in the most
      recent Reserve Report."

      9. AMENDMENT TO SUBSECTION 8.1. Subsection 8.1 of the Credit Agreement is
hereby amended by adding thereto the following paragraphs (d), (e) and (f):

            "(d) AVERAGE DAILY PRODUCTION. Permit the average daily production
      of the Proved Reserves of the Borrower and its Subsidiaries for the
      calendar quarter ending December 31, 1998 to be less than 140 MMCFE/D.

            (e) PROVED RESERVES. Permit the aggregate Proved Reserves of the
      Borrower and its Subsidiaries as of December 31, 1998 to be less than 281
      BCFE.

            (f) WORKING CAPITAL. Permit the Consolidated Working Capital as at
      December 31, 1998 to be less than negative $10,000,000."

      10. AMENDMENT TO SUBSECTION 9(C). Section 9 of the Credit Agreement is
hereby amended by deleting paragraph (c) in its entirety and substituting in
lieu thereof the following:

            "(c) The Borrower or any of its Subsidiaries shall default in the
      observance or performance of any agreement applicable to it contained in
      subsections 4.10, 7.7(a), 7.9 or 7.12 of this Agreement, Section 8 of this
      Agreement or Section 5(b) of the Pledge Agreement; or"

                                                                              10

      11. SCHEDULE 1.1(A), EXHIBIT J AND EXHIBIT K. The Credit Agreement is
