        WHEREAS, the Borrower and the Banks have entered into an Amended and Restated Credit Agreement effective as of May 14, 2004 (as amended, the “Credit Agreement”);

        WHEREAS, the Borrower has requested that the Banks extend the Expiration Date and make certain additional changes to the Credit Agreement, and the Banks have agreed to make such changes; and

        WHEREAS, UFJ is prepared to join the Credit Agreement as a Bank;

        NOW, THEREFORE, in consideration of the premises herein contained and other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

        1.     Defined Terms. All capitalized terms used but not otherwise defined in this Amendment shall have the meaning ascribed to them in the Credit Agreement. Unless otherwise specified, all section references herein refer to sections of the Credit Agreement.

         2.     Amendments to Credit Agreement. The Credit Agreement is amended as follows:

    (a)     The Definition of Advance Line Limit. The definition of “Advance Line Limit” is amended to read as follows:


      “‘Advance Line Limit’ means $50,000,000.00.”


    (b)      The Definition of Borrowing Base Sub-Cap. The definition of “Borrowing Base Sub-Cap” is amended and restated to read as follows:


            “‘Borrowing Base Sub-Cap’ means, on the Closing Date, an amount equal to $200,000,000.00; provided, however, Borrower may elect to change such Borrowing Base Sub-Cap five (5) times during any twelve (12) month period to be any of $100,000,000.00, $125,000,000.00, $150,000,000.00, $175,000,000.00 or $200,000,000.00 (provided that, regardless of any Elected Performance L/C Cap, the Borrowing Base Sub-Cap shall never exceed $200,000,000.00), which modified Borrowing Base Sub-Cap shall continue in effect until again changed by Borrower in accordance with this Agreement, or until automatically reduced as hereinafter set forth. Notwithstanding the foregoing, Borrower may not elect a Borrowing Base Sub-Cap unless Borrower’s Net Working Capital and Tangible Net Worth at the time of election are greater than, or equal to, the amounts specified below:


    (a)            If Borrower elects $200,000,000.00, Borrower’s Net Working Capital and Tangible Net Worth must each be at least $37,375,000.00 plus an amount equal to 30% of the Elected Performance L/C Cap;


    (b)            If Borrower elects $175,000,000.00, Borrower’s Net Working Capital and Tangible Net Worth must each be at least $32,375,000.00 plus an amount equal to 30% of the Elected Performance L/C Cap;


    (c)            If Borrower elects $150,000,000.00, Borrower’s Net Working Capital and Tangible Net Worth must each be at least $27,750,000 plus an amount equal to 30% of the Elected Performance L/C Cap; or


    (d)            If Borrower elects $125,000,000.00, Borrower’s Net Working Capital and Tangible Net Worth must each be at least $23,125,000 plus an amount equal to 30% of the Elected Performance L/C Cap; or


    (e)            If Borrower elects $100,000,000.00, Borrower’s Net Working Capital and Tangible Net Worth must each be at least


2


                     $18,500,000 plus an amount equal to 30% of the Elected Performance L/C Cap.


   

     Borrower shall elect which Borrowing Base Sub-Cap is in effect from time to time by delivering to Agent and Banks a written notice of such election in the form of Exhibit I which is attached hereto. In the event that after Borrower makes a Borrowing Base Sub-Cap election Borrower’s Net Working Capital or Tangible Net Worth as reflected on a Compliance Certificate delivered to Agent are not in compliance with the requirements set forth above, the Borrowing Base Sub-Cap shall be automatically reduced to the appropriate level set forth above to cause compliance with the requirements set forth above, provided that if Borrower fails to qualify for (a), (b), (c), (d) or (e) or fails to elect a Borrowing Base Sub-Cap, then the Borrowing Base Sub-Cap shall be $100,000,000.00. Such reduction shall take place upon Agent’s receipt of such Compliance Certificate or notice of election. NOTWITHSTANDING THE FOREGOING, BORROWER MAY NOT ELECT A BORROWING BASE SUB-CAP IN AN AMOUNT IN EXCESS OF THE THEN TOTAL UNCOMMITTED LINE AMOUNT SUBSCRIBED AS SET FORTH ON SCHEDULE 2.01 FROM TIME TO TIME.


    (c)        The Definition of Economic Basis. The following definition of “Economic Basis” is added to Section 1.01 (Definitions) of the Credit Agreement:


   

      “‘Economic Basis’ means the calculation of financial accounting terms using mark to market of certain assets and liabilities as if the accounting standards of the Emerging Issues Task Force (EITF) under EITF-98-10 (accounting for contracts involved in energy trading and risk management activities) applied.”


    (d)        The Definition of Expiration Date. Clause (a) in the definition of “Expiration Date” is amended to read as follows:


   

      “(a)     November 30, 2006.”


    (e)        The Definition of L/C Sub-Limit Cap. Clause (c) and (e) of the definition of “L/C Sub-Limit Cap” is amended to read as follows:


3


    “(a)              Performance L/Cs — $15,000,000.00 but not to exceed the Elected Performance L/C Cap then in effect;


    (b)               Natural Gas/Transportation L/Cs — $40,000,000.00;


    (c)               Ninety (90) Day Swap L/Cs — $50,000,000.00;


    (d)               Three Hundred Sixty-Five (365) Day Swap L/Cs — $25,000,000.00;


    (e)               Natural Gas/Supply L/Cs — $200,000,000.00 less any amounts outstanding under (a), (b), (c) or (d) above.”


    (f)              The Definition of Maturity Date. The definition of “Maturity Date” is amended to read as follows:


                  “‘Maturity Date’ means November 30, 2007.”

    (g)        Section 1.03 (Accounting Principles). Section 1.03(a) is amended by changing the period following the word “applied” on line three to a comma, and adding the following:


  “except for the financial computations relating to the terms ‘Net Working Capital’ and ‘Tangible Net Worth’ which are to be made on an Economic Basis.”

    (h)        Schedule 2.01 (Uncommitted Line and Uncommitted Line Portions). Schedule 2.01 is deleted and replaced with Schedule 2.01 attached to this Amendment.
