(i)   Section 2.10 shall be amended and restated in its entirety to read as
      follows:

      "2.10 Unused Availability Fee. In addition to interest and all other
      amounts due and payable pursuant to the terms of this Agreement and the
      Note, Borrower agrees to pay to Lender an unused facility fee on the
      unused portion of the Commitment Limit (the "unused portion" being the
      amount by which the Commitment Limit exceeds the outstanding principal
      balance of the Note) from the Effective Date through the Maturity Date, at
      the rate of (a) 0.25% per annum for any amount of such excess up to and
      including 70% of the then effective Commitment Limit or (b) 0.375% per
      annum for such amounts in excess of 70% of the then effective Commitment
      Limit, in each case accrued daily and payable for each three (3) calendar
      month period (each calendar quarter), in arrears fifteen (15) days after
      the last day of each calendar quarter. The amount of the unused facility
      fee shall be calculated each day during the period for which the fee is
      due using an assumed 360 day year.

(j)   Section 2.7 of the Current Loan Agreement shall be deleted in its entirety
      and replaced with the following:

      "2.7 Adjustment of Commitment Limit or Collateral. Lender shall engage a
      third-party consultant, at the sole cost and expense of Borrower, to
      review (a) the Annual Reserve Report delivered to Lender pursuant to
      Section 6.1(c) of this Agreement and (b) the Mid-Year Reserve Report
      delivered to Lender Pursuant to Section 6.1(g) of this Agreement, which
      review shall include preparation of a price-deck established by Lender at
      the lesser of 65% of Base Case NPV9 Asset Value or 80% Downside Case NPV8
      Asset Value for the purpose of establishing a new Borrowing Base. If
      Lender delivers to Borrower written notification that, in Lender's sole
      discretion, the new Borrowing Base does not provide sufficient collateral
      to support Advances up to the Commitment Limit, then the Commitment Limit
      shall be immediately reduced to such an amount as is supported by the
      adjusted Borrowing Base. Provided, however, that, in the event the
      Borrowing Base is reduced pursuant to this Section 2.7, Borrower may
      pledge additional assets as Collateral to Lender as may be necessary, in
      Lender's sole discretion, to support an increase in the reduced Commitment

                                       3


      Limit back to the previously agreed Commitment Limit, and the Commitment
      Limit shall be so adjusted following documentation of such pledge of
      additional assets as Collateral, such documentation to be determined in
      the reasonable discretion of Lender. Provided, further that, if the
      Commitment Limit has been reduced pursuant to this Section 2.7 or pursuant
      to Section 2.9 and in subsequent years the Annual Reserve Report or the
      Mid-Year Reserve Report displays a Borrowing Base that would support a
      Commitment Limit greater than the then-existing Commitment Limit, then the
      Commitment Limit shall be increased to an amount (not to exceed the
      maximum borrowing permissible under the Note) that, in Lender's reasonable
      discretion, would be supported by the information regarding the Collateral
      contained in such Annual Reserve Report."

(k) A new Section 2.12 shall be added to the Current Loan Agreement that reads
as follows:

      "2.12 Commitment Limit Redetermination Requests. No more than one time in
      each of the Borrower's fiscal year, the Borrower may send a written
      request to the Lender to request an increase in the Commitment Limit (a
      "Redetermination Request"). Each Redetermination Request shall include the
      amount of the requested increase in the Commitment Limit, reasonable
      detail regarding the need for such increase in the Commitment Limit and
      information regarding the Borrowing Base necessary to support the
      requested increased Commitment Limit. Upon receipt of a Redetermination
      Request, the Lender shall negotiate with Borrower in good faith regarding
      the terms and conditions of such increase, provided, however, that it
      shall be in the Lender's sole and absolute discretion whether to increase
      the Commitment Limit pursuant to any Redetermination Request. Upon
      resolution of the requested increase in the Commitment Limit pursuant to a
      Redetermination Request, the Borrower shall pay to the Lender an amount
      equal to the Borrowing Base Redetermination Fee, if any."

(l) A new Section 2.2(c) shall be added to the Current Loan Agreement that reads
as follows:

      "(c) Each Request for an Advance delivered to the Lender pursuant to
      Section 2.2(a) above shall include a notification to the Lender if the
      Borrower intends all or any portion of the Advance to be subject to a
      Selected LIBOR specifically indicating which Selected LIBOR will apply.
      Each such interest rate election shall be irrevocable and shall specify
      (i) the Advances to which such interest rate election applies and, if
      different options are being elected with respect to different portions
      thereof, the portions thereof to be allocated to each resulting Advance,
      and (ii) the effective date of the election made pursuant to such interest
      rate election. Notwithstanding the foregoing, the Borrower acknowledges
      and agrees that no more than three separate tranches of Advances may be
      outstanding under any Selected LIBOR. If there are more than three
      separate tranches of LIBOR Advances outstanding when a Request for Advance
      is delivered or if no interest rate election is included in a Request for
      Advance, all Advances made pursuant to such Request for and Advance shall
      be made at the Prime Rate."


                                       4

            any related documents.


(n) A new Section 8.6 shall be added to the Current Loan Agreement that reads as

            of (a) EBITDAX to (b) Accrued Facility Interest Expense and Fees of
            no less than 3.50, calculated at the end of each fiscal quarter.
