<PAGE>

               8.1.11 Change of Control. The Sponsor (which for purposes of this
          Section 8.1.11 shall be deemed to include Sponsor's Affiliates, except
          Renegy Holdings (as defined below)) shall cease to directly or
          indirectly maintain at least 50.1% of the economic interests in and
          voting power of Borrowers (a "Change of Control"); provided, that, in
          the event the membership interests in Borrowers are transferred to
          Renegy Holdings, Inc. ("Renegy Holdings") pursuant to a transaction in
          substantially the form and substance as contemplated by the
          Contribution and Merger Agreement, as amended, included as an annex to
          Renegy Holdings' Registration Statement on Form S-4 filed with the
          Securities and Exchange Commission on August 9, 2007 and pursuant to
          which Sponsor will be issued shares of common stock of Renegy Holdings
          (the "Transaction"), a Change of Control shall not be deemed to occur
          if Sponsor's economic interests in and voting power of Renegy Holdings
          falls below 50.1% after the one year anniversary of the
          Term-Conversion Date provided Renegy Holdings continues to maintain
          directly or indirectly 100% of the economic interests in and voting
          power of Borrowers and Sponsor continues to exercise titular and
          effective managerial control of Renegy Holdings; provided, further,
          that upon Sponsor's death, a Change of Control shall not be deemed to
          occur until one year has passed and will not be deemed to occur if as
          of such time 100% of the economic and voting interests in Borrowers
          (or, in the event the Transaction shall have occurred, Renegy
          Holdings) maintained by Sponsor at the time of Sponsor's death have
          been transferred, provided that such interests constitute at least
          50.1% of the economic and voting interests in Borrowers (or, in the
          event the Transaction shall have occurred, Renegy Holdings), so long
          as:

               (a) the applicable transferee is a corporation, limited liability
          company or limited partnership organized or formed in the United
          States or a state or commonwealth therein;

               (b) at the time of the proposed disposition, the applicable
          transferee's unsecured senior long-term debt has a rating of at least
          Baa3 by Moody's and BBB- by S&P;

               (c) the electric energy generation business is a substantial part
          of the applicable transferee's business;

               (d) on or before the date of any such disposition, the applicable
          transferee (or its applicable subsidiary) enters into a pledge
          agreement in substantially the form of Exhibit D-3-A, pursuant to
          which such transferee (or subsidiary) shall pledge all of its
          ownership interests in Borrowers to Collateral Agent (or, in the event
          the Transaction shall have occurred, the ownership interests in
          Borrowers shall continue to be pledged by Renegy Holdings to
          Collateral Agent) and executes and delivers all other applicable
          Credit Documents as requested by Administrative Agent; and

               (e) on or before the date of any such disposition, the applicable
          transferee delivers to Administrative Agent (addressed to the Secured
          Parties)

                                        2

<PAGE>

          such opinions, resolutions, certificates and other evidence as
          Administrative Agent may reasonably request (all of which shall be in
          form and substance reasonably satisfactory to Administrative Agent) to
          ensure Administrative Agent's reasonable satisfaction as of the date
          of any such disposition with the matters covered by Sections 3.1.1
          through 3.1.6(a), 3.1.8 and 3.1.18 (with respect solely to the
          applicable transferee and, if reasonably requested by Administrative
          Agent, Borrowers and, if the Transaction shall occur, Renegy
          Holdings);

          provided further that, any transaction involving the effective
          transfer by Sponsor of interests to a purchaser of production tax
          credits or similar tax attributes arising from ownership of a Borrower
          shall not constitute a Change of Control so long as the Sponsor
          directly or indirectly maintains at least 50.1% of the voting
          interests in the Borrowers.

          (b) Section 8.1.18 is hereby deleted in its entirety and replaced with
     the following:

               8.1.18 Paper Sludge Shortfall. The Abitibi mill shall for any
          reason have ceased delivery of paper sludge to the Project in an
          amount at least equal to 250 bone-dry tons per day, for a period of 45
          days, or Abitibi has announced that it intends such cessation, and
          Borrowers shall not have in place at the Site or available from
          counterparties under contracts a fuel supply stockpile such that (a)
          during the first year after such moment (i.e., after either the end of
          such 45-day period or the end of the 45-day period following the time
          of Abitibi's announcement, as applicable), would allow the Project to
          continue operating without paper sludge at a capacity of 24.5 MW for
          400 days and (b) from and after the first anniversary of such moment,
          would allow the Project to continue operating without paper sludge at
          a capacity of 24.5 MW for 800 days (the amount of fuel described in
          clause (a) or clause (b), as applicable, the "Alternative Fuel
          Stockpile").

          (c) The Fuel Stockpile definition in Exhibit A to Credit Agreement is
     hereby deleted in its entirety and replaced with the following:

               "Fuel Stockpile" means a 2.5-year availability of fuel (other
          than paper sludge) either on the Site or available from counterparties
          on contractual terms reasonably acceptable to the Administrative
          Agent, provided that at least a 1-year stockpile of such 2.5-year
          availability of fuel (other than paper sludge) shall be on the Site at
          all times and provided further that such 2.5-year availability of fuel
