     This CONSENT AND AGREEMENT (this "Consent"), dated as of August 16th, 2006,
is made by and between ARIZONA PUBLIC SERVICE COMPANY, an Arizona corporation
("APS"), and SNOWFLAKE WHITE MOUNTAIN POWER, LLC, an Arizona limited liability
company ("Assignor"), for the benefit of COBANK, ACB, as administrative agent
for the lenders, (in such capacity, "Lender").

                                    RECITALS

     A. Assignor has entered into that certain Credit Agreement relating to
financing for the development, construction, installation, operation and
maintenance of its biomass power plant located in Snowflake, Arizona (the
"Project"), dated as of August   ,2006, among Assignor, Renegy, LLC, and Renegy
Trucking, LLC (collectively, the "Borrowers"), Lender, the LC Issuer (as defined
therein), and the Lenders (as amended, modified and supplemented from time to
time, the "Credit Agreement"). Assignor and Lender have also entered into a
security agreement (the "Security Agreement"), under which Assignor has agreed
to assign its interest under the Assigned Agreement, as defined below, to Lender
as collateral for the loan and other obligations of the Borrowers under the
Credit Agreement.

     B. APS and Assignor are parties to the Master Power Purchase and Sale
Agreement, dated September 6, 2005, together with the Amended and Restated
Transaction Confirmation dated August 16th, 2006 (as amended, modified and
supplemented from time to time, the "Assigned Agreement").

     C. It is a requirement of the Lender under the Credit Agreement and/or the
Security Agreement relating to financing for the Project that APS and the
Assignor shall have executed and delivered this Consent.

                                   AGREEMENT

     NOW, THEREFORE, APS hereby agrees as follows:

     1. Definitions. Unless otherwise defined herein, all capitalized terms used
in this Consent shall have the meanings given to them in the Assigned Agreement.

     2. Consent and Agreement. APS consents to the collateral assignment of the
Assigned Agreement, by Assignor to Lender, and agrees with Lender as follows:

          a. APS consents to the transfer of all the Assignor's right, title and
interest to, in and under the Assigned Agreement, to Lender, solely in
connection with the enforcement of its security interest under the terms of the
Security Agreement, at a foreclosure sale by judicial or non-judicial
foreclosure and sale or by a conveyance by Assignor in lieu of foreclosure and
agrees that upon such enforcement, foreclosure, sale or conveyance APS shall
recognize Lender, but if and only if Lender assumes all

obligations of Assignor under the Assigned Agreement and otherwise satisfies
and complies with all requirements of the Assigned Agreement.

          b.   At all times that this Consent remains in effect, APS will not
without the prior written consent of Lender (such consent not to be
unreasonably withheld, delayed or conditioned), cancel or terminate the
Assigned Agreement or consent to or accept any cancellation or termination
thereof by Assignor except as provided in the Assigned Agreement and in
accordance with Section 2(c) of this Consent.

          c.   APS shall, concurrently with the delivery of any notice of an
Event of Default to the Assignor under the Assigned Agreement, provide to
Lender a copy of any such default notice, in each case pursuant to Section 4 of
this Consent. If APS does not deliver such default notice to Lender when it
delivers such notice to the Assignor under the Assigned Agreement, the Lender's
applicable cure period under the Assigned Agreement and this Consent shall
begin on the date on which such notice is received by Lender. Upon the
occurrence of an Event of Default of the Assignor (subject to the expiration of
the relevant cure periods provided to Assignor under the Assigned Agreement),
APS shall not terminate the Assigned Agreement unless it provides Lender with a
notice of Assignor's Event of Default and affords Lender a period of thirty
(30) days to cure such Event of Default. If possession of the Facility is
necessary for Lender to cure Assignor's Event of Default and Lender commences
foreclosure proceedings against Assignor within thirty (30) days of receiving
notice of such Event of Default from APS, Lender shall be allowed a reasonable
additional period to complete such foreclosure proceedings, such period not to
exceed ninety (90) days. In the event Lender succeeds to Assignor's interest in
the Facility, Lender shall cure any and all Events of Default of the Assignor
in existence under the Assigned Agreement at the time which are capable of
being cured and which are not personal to the Assignor.

          d.   In the event Lender succeeds to or assumes Assignor's interest
under the Assigned Agreement pursuant to the exercise of any rights hereunder,
Lender shall cure any defaults for failure to pay amounts owed under the
Assigned Agreement and any other defaults of the Assignor under the Assigned
Agreement that do not constitute non-curable defaults that are personal to the
Assignor. Lender shall have the right to assign all of its interest in the
Assigned Agreement to a person or entity to whom the Facility is transferred,
so long as such person or entity is of equal or better credit quality than the
Assignor, as determined by APS in its reasonable discretion; provided such
transferee assumes all obligations of Assignor or Lender under the Assigned
Agreement and otherwise satisfies and complies with all requirements of the
Assigned Agreement. Upon such assignment, Lender shall be released from any
further liability thereunder accruing from and after the date of such
assignment to the extent of the interest.

     3.   Effect of this Consent. This Consent shall not change, extend or
alter the Commercial Operation Date set forth in the Assigned Agreement.
Furthermore, no additional cure periods provided to Lender in Section 2(c) of
this Consent shall extend the Commercial Operation Date beyond July 1, 2008.

unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

counterparts, and when executed and delivered by all the parties listed below,
shall constitute a single binding agreement.

     10. Interpretation. All references in this Consent to any document,

include all documents, instruments or agreements issued or executed
