        2.2.    FPL and/or Enron, directly or indirectly through their
                respective affiliates, have an interest in each of the Projects.

                Agreement Addressing Renewable Energy Pricing and Payment
                Issues, dated on or about June 19, 2001, as amended by Amendment
                No. 1 to Agreement Addressing Renewable Energy Pricing and
                Payment Issues, dated on or about November 30, 2001 (each, as
                amended, a "Renewable Agreement" and, together, the "Renewable
                Agreements"). The Renewable Agreements, among other things,
                contain certain provisions applicable to the pricing terms of
                the PPAs.

        2.4.    Certain of the Parties and/or their affiliates are presently
                engaged in civil litigation in a California superior court

                and Exchange Commission ("SEC") and/or the Federal Energy
                Regulatory Commission ("FERC") which, among other things,
                concern claims arising from the relationship between Edison, as
                purchaser, and the PPA Sellers, as seller, under the PPAs.

        2.5.    On December 2, 2001, Enron Corp. (Case No. 01-16034 AJG), and
                subsequently certain of its affiliates, including, without
                limitation, Enron Wind, LLC, Enron Wind Systems, LLC and ZWHC
                LLC, filed voluntary petitions for relief under Chapter 11 of
                Title 11 of the United States Code, as amended, (collectively,
                the "Enron Bankruptcy") in the U.S. Bankruptcy Court for the
                Southern District of New York ("Bankruptcy Court").

        2.6.    It is the Parties' intentions to resolve the claims referenced
                in Section 2.4 through (i) this Master Definitive Agreement, and
                (ii) through the PPA amendments entered into by Edison and the
                individual PPA Sellers, the form of which is attached hereto as
                Attachment E (the "PPA Amendments"). This Master Definitive
                Agreement and the PPA Amendments are collectively referred to
                herein as the "Definitive Agreements." In entering into the
                Definitive Agreements, each of the PPA Sellers is acting on
                behalf of itself and (in its capacity as Project Manager under
                the applicable PPA) all others, if any, who have an ownership or
                other interest in the PPA Seller's respective Project(s), or any
                portion thereof.

        2.7.    Prior to the execution of the Definitive Agreements, Edison,
                Enron and FPL agreed to take certain actions in anticipation of
                the Definitive Agreements being executed, as set forth in a
                confidential Memorandum of Understanding, dated December 19,
                2002 ("MOU"). The MOU memorialized both the essential terms that
                the Parties agreed to include in the Definitive Agreements as
                well as those actions that the Parties agreed to take prior to
                the execution of the Definitive Agreements. The MOU

                immediately upon the parties to the MOU upon its execution as

                after December 1, 2002 at 12:01 A.M. Pacific Time shall be
                recalculated using the "adjusted" capacity price shown in
                Attachment A as to the Project, and, effective as of the
                Satisfaction Date, the difference (without interest) shall be
                applied as a credit to Edison against the next payment due the
                Project for both energy and capacity pursuant to the PPA;
                provided, however, that if the amount of such credit to Edison
                exceeds the full amount owing in the first payment due the
                Project after the Satisfaction Date, Edison shall fully offset
                the current amount owed under the PPA by Edison and apply the
                remaining balance of the credit as an offset to each successive
                payment due the Project by Edison thereafter in the same manner
                until the credit is fully utilized (all such offsets accruing as
                of the Satisfaction Date).

        7.4.    If the credit owed Edison for the Project has not been fully
                utilized by the conclusion of three successive billing cycles,
                then Edison may, at its option, invoice the Project for the
                remaining, unutilized portion of the credit, which invoice shall
                be paid by the Project within ten (10) days of receipt.

        7.5.    Following the Satisfaction Date, capacity payments for
                deliveries by the Project made from and after December 1, 2002
                for which payment has not yet been made shall be calculated
                using the applicable adjusted as-available capacity price set
                forth in Attachment A and incorporated in each respective PPA
                Amendment.

8.      ENERGY RATE TO TRACK CPUC CHANGES

        As memorialized in the PPA Amendments, each PPA will, upon the
        occurrence of the Satisfaction Date, be amended as of the Effective Date
        to provide as follows:

                                      - 7 -


                                  CONFIDENTIAL
                         CONTAINS PRIVILEGED INFORMATION
                                 DO NOT RELEASE

        8.1.    In the event that the CPUC changes the applicable rate for
                energy (including, but not limited to, changes to the
                CPUC-approved SRAC rate) that is generally applicable, during
                any part of the remaining term of the PPAs, to those entities
                owning renewable QFs that signed a Renewable Agreement and is
                applicable under the PPAs, then, on the date on which such
                change becomes effective, and continuing until such time as such
                rate is no longer applicable pursuant to the terms of the PPAs,
                as amended, the energy rate for power purchases made pursuant to
                the PPAs shall, without further action by the Parties or
                otherwise, be the revised rate adopted by the CPUC.

        8.2.    Nothing herein shall preclude any Party from seeking rehearing
                or other appropriate review of any CPUC order(s) or decision(s)
                effecting a change in rate(s) for energy sales under the PPAs or
                from fully participating in any CPUC proceedings pertaining to
                such change or proposed change.

        8.3.    Notwithstanding any of the other provisions of this Article 8,
                nothing in this Article 8 shall be construed as modifying or
                diminishing any rights or obligations of the Parties under the
                energy rate provisions of the Parties' Renewable Agreements,
                including, but not limited to, the provisions therein applicable
                to the Fixed Rate associated with the Fixed Rate Period, nor
                shall anything in this Article 8 be construed as conferring upon
                the CPUC any rate setting authority that it does not already
                possess with respect to the PPAs, as amended pursuant to the
                Renewable Agreements.

9.      TREATMENT OF OUTSTANDING ACCOUNTS RECEIVABLE BALANCES, IF ANY

        To the extent Edison has not previously paid a Project its applicable
        Final Payment Amount as shown on Attachment B:

        9.1.    Pending the occurrence of the Satisfaction Date, Edison may and
                will continue to withhold the Final Payment Amount for the
                Project, as well as any accrued, but unpaid, interest thereon.

        9.2.    On the Satisfaction Date, (i) the Final Payment Amount for the
                Project, including all accrued interest thereon, if any, shall,
                if not previously paid by Edison, be deemed to have been paid in
                full, without any further payment by Edison; and (ii) all
                provisions of a Renewable Agreement that were conditioned on
                Edison's payment of the Final Payment Amount shall be deemed to
                have become fully effective as to the Project as if such Final
                Payment amount had been paid in accordance with the applicable
                Renewable Agreement.

10.     WAIVER OF CERTAIN QF REQUIREMENTS

                                      - 8 -


                                  CONFIDENTIAL
                         CONTAINS PRIVILEGED INFORMATION
                                 DO NOT RELEASE

        10.1.   Effective on the Satisfaction Date, each Project's PPA will be
                amended, as memorialized in the PPA Amendments, to provide that
                the Project shall not, on or after such date, be required to
                satisfy any ownership or size limitation requirements applicable
                to QFs, including, without limitation, those requirements set
                forth in 16 U.S.C. Section 796(17) (A) (ii), 16 U.S.C. Section
                796(17)(C)(ii) and 18 C.F.R. Sections 292.204(a)(1) and 292.206
                (collectively, the "Waived QF Requirements").

        10.2.   The PPA Amendments shall not affect any other rights,
                obligations or liabilities of either Edison or the Projects, and
                each of them, arising under state and federal law, and neither
                Edison nor the Projects shall assert such PPA Amendments as a
                basis for avoiding, amending or modifying any terms of each
                Project's PPA other than those that would require compliance
                with the Waived QF Requirements absent the PPA Amendment.

        10.3.   Without limiting the foregoing, it is expressly understood that
                although, upon the occurrence of the Satisfaction Date, each
                Project will no longer be required to comply with the Waived QF
                Requirements, and therefore will no longer be required to be or
                certify as a QF under PURPA and FERC's regulations implementing
                PURPA, the Projects, and each of them, will nonetheless, except
                as to the Waived QF Requirements, continue to generate power for
                sale to Edison under the PPAs in the manner required by PURPA,
                16 U.S.C. Section 796(17)(A)(i), 16 U.S.C. Section 796(17)(B),
                and 16 U.S.C. Section 796(17)(C)(i) (but not including, in
                addition to the Waived QF Requirements, any QF certification
                requirements), and FERC's regulations implementing the foregoing
                requirements set forth in this Section, 18 C.F.R. Section
                292.204 (b), as wind power production facilities, and further
                that, with the exception of the Waived QF Requirements, the PPAs
                applicable to the Projects shall continue to be administered by
                Edison as QF contracts.

        10.4.   It is expressly understood that in connection with the
                Definitive Agreements, the Projects intend to seek approval of
                the rates provided in the PPAs, as amended pursuant to the
                Renewable Agreements and the Definitive Agreements, pursuant to
                Section 205 of the Federal Power Act, as amended. No Party shall
                assert that either the seeking or the granting of such rate
                approval constitutes a basis for altering, amending or avoiding
                any of the terms or conditions of a PPA, as amended.

11.     RELEASES; WAIVER OF CIVIL CODE SECTION 1542

        11.1.   As of the Satisfaction Date, Edison, on the one hand, and Enron,
                FPL and each PPA Seller (on behalf of itself, its respective
                Project and (in its capacity as Project Manager under the
                applicable PPA) all others who have an ownership or other
                interest in such Project or any portion of it), on

                                      - 9 -


                                  CONFIDENTIAL
                         CONTAINS PRIVILEGED INFORMATION
                                 DO NOT RELEASE

                the other hand, mutually release and discharge one another, and
                each of their respective affiliates, parents, shareholders,
                directors, officers, employees, agents and advisors, partners,
                joint venturers, predecessors, successors and assigns, and all
                others who have an ownership interest in such Project or any
                portion of it from any and all claims, obligations, losses,
                causes of action, allegations, demands and liabilities, of
                whatsoever kind and nature, character and description, whether
                in law or equity, whether sounding in tort, contract or under
                other applicable law, whether known or unknown, whether
                anticipated or unanticipated, or whether asserted or unasserted,
                of or to a Party (collectively, "Claims") based on or arising
                out of: (i) lack of compliance by the Project or its affiliates
                with the Waived QF Requirements as to such Projects at any time
                prior to the Satisfaction Date; (ii) Edison's Claims asserted in
                the SEC Proceeding; (iii) Edison's Claims in the FERC
                Proceeding; (iv) all Claims asserted on behalf of any of the
                Projects or by Edison in the Cabazon Litigation and/or, if
                applicable, which concern or pertain to Edison's withholding or
                non-payment of the Final Payment Amount for any of the Projects
                and/or any accrued interest thereon; and (v) any Claims which
                arise from any subsequent FERC proceeding or any other
                proceeding regarding the issue of QF status as it pertains to
                the Waived QF Requirements that may affect payment obligations
                under the PPAs applicable to the Projects.

        11.2.   Each of the Parties believes that it is fully familiar with the
                facts giving rise to this settlement, including any facts that
                have arisen as the result of any investigations of Enron Corp.
                and its affiliates by governmental entities, including, without
                limitation, by FERC, the United States Congress and the State of
                California, in relation to the conduct of Enron Corp. and its
                affiliates in the electric power market, but agrees that the
                Definitive Agreements shall remain fully effective and binding
                as to each of them even if the facts turn out to be different
                from what they now believe them to be or there are additional
                future investigations of Enron Corp. and its affiliates as to
                the matters which are the subject of the Definitive Agreements.
                Further, as to specific matters released in Section 11.1, each
                of the Parties waives the benefit of California Civil Code
                Section 1542 (or any similar law from another jurisdiction).
                Section 1542 of the California Civil Code provides as follows:

                                "A GENERAL RELEASE DOES NOT
                        EXTEND TO CLAIMS WHICH THE
                        CREDITOR DOES NOT KNOW OR SUSPECT
                        TO EXIST IN HIS FAVOR AT THE TIME OF
                        EXECUTING THE RELEASE, WHICH IF
                        KNOWN BY HIM MUST HAVE
                        MATERIALLY AFFECTED HIS
                        SETTLEMENT WITH THE DEBTOR."

                                     - 10 -


                                  CONFIDENTIAL
                         CONTAINS PRIVILEGED INFORMATION
                                 DO NOT RELEASE

                Such waiver is not a mere recital but a knowing and intentional
                waiver of a known right undertaken after consultation with
                counsel and with a full understanding of the risks and
                uncertainties inherent in such a release. Notwithstanding the
                waiver of Civil Code Section 1542, the Parties, and each of
                them, acknowledge that the releases in the Definitive Agreements
                are specific to the matters set forth in the releases and are
                not intended to create general releases as to all Claims, or
                potential Claims, between the Parties.

        11.3.   As of the Satisfaction Date, Edison will release and discharge
                the Sagebrush Partnership and its successors and assigns
                (provided that the effectiveness of the release in this Section
                11.3, but no other provision of the Definitive Agreements, shall
                be expressly conditioned on the Sagebrush Partnership and its
                successors and assigns providing a mutual release reasonably
                satisfactory to Edison prior to the Satisfaction Date), in each
                case, from any and all Claims (as defined in Section 11.1 above)
                based on or arising out of: (i) lack of compliance by any of the
                Projects or their affiliates with the Waived QF Requirements as
                to such Projects at any time prior to the Satisfaction Date;
                (ii) Edison's Claims asserted in the SEC Proceeding; (iii)
                Edison's Claims in the FERC Proceeding; (iv) all defenses and
                Claims asserted by Edison in the Cabazon Litigation; and (v) any
                Claims which arise from any subsequent FERC proceeding or any
                other proceeding regarding the issue of QF status as it pertains
                to the Waived QF Requirements.

        11.4.   As of the Satisfaction Date, the release provisions set forth in
                the Renewable Agreement for each Project shall be deemed
                ratified by the applicable PPA Seller and Edison, confirming
                that such release provisions are, as of such date, in full force
                and effect and not subject to any further conditions, in
                accordance with the terms, conditions and applicable dates, as
                provided in such release provisions without modification.

        11.5.   Effective on the Satisfaction Date, Edison, on the one hand, and
                Enron, FPL, and the PPA Sellers, on the other hand, represent
                and warrant each to the other that, as of the date on which each
                such Party executes the Master Definitive Agreement, it is,
                without investigation, unaware of any defenses to the validity
                of the release provisions set forth in the Renewable Agreements,
                other than those expressly released or waived in the Definitive
                Agreements.

12.     COVENANTS AT EXECUTION OF THE DEFINITIVE AGREEMENTS

        12.1.   Subject to the provisions of Section 12.3, each Party covenants
                not to challenge or seek to modify pursuant to Section 206 of
                the Federal Power Act either the adjusted capacity rate provided
                for in Attachment A or the Fixed Rate associated with the Fixed
                Rate Period.

                                     - 11 -


                                  CONFIDENTIAL
                         CONTAINS PRIVILEGED INFORMATION
                                 DO NOT RELEASE

        12.2.   Each PPA Seller (on behalf of the applicable Project) covenants
                that it will not assert rate authority obtained pursuant to
                Section 205 of the Federal Power Act, as amended, as a basis,
                whether directly or indirectly, for avoiding any provision of
                the PPM, as amended.

        12.3.   The covenants of Sections 12.1 and 12.2 shall terminate on the
                Termination Date, if any.

        12.4.   Each Party hereto represents and warrants that it has obtained
                all necessary approvals to enter into, execute and, upon receipt
                of the Required. Regulatory Approvals, to implement, the
                Definitive Agreements. Enron further represents and warrants
                that the transaction contemplated by the MOU has been submitted
                to the Enron Bankruptcy Creditors' Committee and that the
                Creditors' Committee has indicated, pursuant to the manner in
                which such indications have generally been given in the Enron
                Bankruptcy, that (i) it has no objection to Enron seeking
                approval of the Bankruptcy Court for such transaction, and (ii)
                it has no present intention to file an objection to such
                transaction.

        12.5.   Each PPA Seller, on behalf of itself and its applicable Project,
                specifically represents that the approvals of those lenders and
                other investors or participants in the Project which are
                necessary or deemed necessary or advisable by such PPA Seller,
                as well as such other consents and approvals, if any, which may
                be necessary or deemed necessary or advisable by such PPA
                Seller, in each case, under the PPA and various other Project
                agreements, have been obtained.

        12.6.   Each Party represents and warrants that it has not, at any time
                prior to its execution of the Definitive Agreements, assigned or
                otherwise transferred, or purported to assign or otherwise
                transfer, to any party, directly or indirectly, voluntarily,
                involuntarily or by operation of law, any Claims it may have
                against the other Party, or any Claims being released by the
                provisions of Section 11.1 of this Master Definitive Agreement
                or which are encompassed within the release provisions of the
                Renewable Agreements for the Projects.

13.     ESTOPPEL LETTER

        For a period of eighteen (18) months after the Satisfaction Date, so
        long as a Project is in compliance with its PPA and the terms and
        conditions of the Definitive Agreements after taking into consideration
        the effect of the releases and waivers contemplated in the Definitive
        Agreements and in the Renewable Agreement for the Project, Edison will,

        OTHER MATTERS

        14.1.   Within five (5) Business Days following the Satisfaction Date,
                Edison will withdraw with prejudice, or, where required by
                applicable rules of procedure, seek permission from the
                applicable agency to withdraw with prejudice: (i) any and all
                interventions, complaints, allegations, and motions in the SEC
                Proceeding; and (ii) any and all interventions, complaints,
                allegations, and motions in the FERC Proceeding that are based
                on the Claims released and/or waived in the Definitive
                Agreements, including, but not necessarily limited to, filing a
                Notice of Withdrawal pursuant to 18 C.F.R. Section 385.216 for
                the purpose of withdrawing Edison's petition for declaratory
                order and complaint in FERC Docket No. EL03-19-000.

        14.2.   Within five (5) Business Days following the Satisfaction Date,
                Edison will withdraw and/or waive any claims it has asserted in
                the Enron Bankruptcy that are based on the Claims released
                and/or waived in the Definitive Agreements. Edison shall not be
                obligated to withdraw and/or waive any other claim that it has
                filed in the Enron Bankruptcy, such as, but not limited to, its
                claim against Enron Corp. based on alleged energy market
                manipulation and related activities.

        14.3.   Within five (5) Business Days following the Satisfaction Date,
                the PPA Sellers who are parties to the Cabazon Litigation shall
                cause to be filed with the superior court a request for
                dismissal of the Cabazon Litigation in its entirety with
                prejudice.

        14.4.   Each of the Parties shall bear its own attorneys' fees and costs
                in the FERC Proceeding, the SEC Proceeding, and the Cabazon
                Litigation.

        14.5.   Each of the Parties covenants that, after the Satisfaction Date,
                it will not bring, enter into, participate or intervene in or
                otherwise pursue, directly or indirectly, any subsequent actions
                or proceedings arising from or related to any of the Claims
                released in the Definitive Agreements, except for the purpose of
                enforcing any of the terms of the Definitive Agreements.

        14.6.   As of the Satisfaction Date, Edison, on the one hand, and Enron,
                FPL, and each PPA Seller, on the other hand, as to each other,
                irrevocably waive, discharge and agree to forego any rights they
                have or may have to the benefit of any ruling(s) of FERC or the
                SEC in the FERC Proceeding and/or the SEC Proceeding (or any
                subsequent proceedings which concern the same general factual
                allegations as form the basis of the Claims

                released and/or waived in the Definitive Agreements) in respect
                of the rates Edison must pay, refunds of prior amounts paid by
                Edison, or other economic effect upon or under the PPA for each
                of the Projects. To the extent any Party actually receives any
                funds from another Party on account of such rights or benefits
                the receipt of which would be inconsistent with the waiver,
                discharge, etc. provided for in this paragraph, such Party will
                promptly pay such funds over to the other Party.

15.     CONDITIONS PRECEDENT TO EFFECTIVENESS OF DEFINITIVE AGREEMENTS;
        REGULATORY AND OTHER APPROVALS

        Certain terms and conditions of the Definitive Agreements will not
        become effective until the Satisfaction Date, the occurrence of which
        requires that the Required Regulatory Approvals first be either obtained
        or waived in writing. For this purpose "Required Regulatory Approvals"
        means the approval of each regulatory agency or court described in
        Sections 15.1, 15.2 and 15.3 below with respect to which the responsible
        agency or court has issued an order meeting the finality requirements
        set forth below for each respective agency or court and which approves
        the Definitive Agreements without modification thereto which is
        unacceptable, in its reasonable business judgment, to a Party whose
        rights or obligations under the Definitive Agreements are materially
        adversely affected by such modification. The Parties agree to cooperate
        and use their reasonable best efforts (which shall not require the
        taking of any appeal beyond the initial court or agency from which
        approval has been sought and which appeals, if taken, shall not extend
        the Satisfaction Date absent the agreement of the Parties) to obtain the
        Required Regulatory Approvals promptly. The Parties agree to notify each
        other promptly in writing in the event it is determined that any
        Required Regulatory Approval will not be forthcoming. In such event, any
        Party may notify the SEC, FERC, the CPUC, the Bankruptcy Court and/or
        the court in the Cabazon Litigation of such non-approval without prior
        notice to the other Parties.

        15.1.   FERC APPROVAL:

                15.1.1  The Parties acknowledge that FERC Approval is a
                        condition precedent to the occurrence of the
                        Satisfaction Date. "FERC Approval" means that FERC has
                        issued an order approving the Definitive Agreements and
                        satisfying the other requirements set forth in Section
                        15.1.3 as to which (1) rehearing of the order has been
                        denied or the time for requesting rehearing of the order
                        has expired and no request for rehearing has been filed
                        and (2) as of the date on which all other conditions
                        precedent to the occurrence of the Satisfaction Date
                        have been satisfied, no stay of the order has been
                        granted by FERC or a court of competent jurisdiction and
                        no motion or

                                     - 14 -

                                 DO NOT RELEASE

                        other request for stay of the order is then pending
                        before FERC or a court of competent jurisdiction.

                15.1.2  The Parties understand that Edison, on the one hand, and
                        Enron, FPL and the Enron affiliates named as respondents
                        in the FERC Proceeding, on the other hand, for the
                        purpose of obtaining FERC Approval, shall jointly file
                        at FERC an offer of settlement pursuant to 18 C.F.R.
                        Section 385.602 within 15 days after the Master
                        Definitive Agreement has been executed or within such
                        other time period as may be agreed upon by Edison, Enron
                        and FPL.

                15.1.3  FERC Approval, as contemplated herein, shall include not
                        only the reasonableness of the terms and provisions of
                        the Definitive Agreements but shall expressly include
                        acceptance of the rates provided for in each PPA, as
                        amended pursuant to the applicable Renewable Agreement
                        and the Definitive Agreements, under Section 205 of the
                        Federal Power Act, so that no further FERC approval or
                        FERC proceedings of any kind are required in connection
                        with the rates applicable to the amended PPAs and the
                        Projects; provided, however, that FERC approval of any
                        application related to the transmission facilities used
                        to deliver power from the Projects to Edison shall not
                        be a condition precedent to the occurrence of the
                        Satisfaction Date. The Section 205 application seeking
                        FERC Approval shall include a request that FERC's
                        acceptance of such rates shall have no precedential
                        effect as to any other power seller or contract that is
                        not expressly subject to the terms and conditions of the
                        Definitive Agreements or as to any of the Parties or PPA
                        Sellers with respect to other disputes that are not
                        addressed in the Definitive Agreements.

                15.1.4  Nothing in this Article 15 shall prevent a PPA Seller or
                        Edison from seeking or opposing any action by the CPUC
                        that is generally applicable to QFs that would have the
                        effect, whether directly or indirectly, of changing a
                        rate or other provision of a PPA or other power purchase
                        agreement between Edison and a PPA Seller that has been
                        or continues to be subject to the jurisdiction of the
                        CPUC.

                15.1.5  Nothing in this Article 15 or elsewhere in the
                        Definitive Agreements shall prevent, or be construed to
                        prevent, Edison or a PPA Seller from enforcing the terms
                        of a PPA, except as expressly provided in the Definitive
                        Agreements.

                                 DO NOT RELEASE

                15.1.6  Absent the agreement of the Parties to the proposed
                        change, the standard of review for changes by the FERC
                        to the rates and other terms of the PPAs, as amended,
                        shall be the "public interest" standard of review set
                        forth in United Gas Pipe Line Co. v. Mobile Gas Service
                        Corp., 350 U.S. 332 (1956) and Federal Power Commission
                        v. Sierra Pacific Power Co., 350 U.S. 348 (1956);
                        provided that nothing herein shall affect or modify any
                        provision of a PPA or of any other power purchase
                        agreement that provides for rate or administrative
                        changes based upon determinations of the CPUC that are
                        applicable generally to QFs.

        15.2.   CPUC APPROVAL:

                15.2.1  The Parties acknowledge that CPUC Approval is a
                        condition precedent to the occurrence of the
                        Satisfaction Date. "CPUC Approval" means that the CPUC
                        has issued a final decision, no longer subject to
                        appeal, that approves the Definitive Agreements and
                        satisfies the other requirements set forth in Section
                        15.2.2. However, Edison in its sole discretion may
                        unilaterally waive CPUC Approval as to all or any
                        individual aspects of the Definitive Agreements
                        requiring such approval at any time by giving notice of
                        such waiver in writing to the affected PPA Sellers and
                        the other Parties hereto.

                15.2.2  CPUC Approval shall require findings that the Definitive
                        Agreements and the rates provided for in such Definitive
                        Agreements, are reasonable and that payments made
                        pursuant to the PPAs, as modified by the PPA Amendments,
                        are fully recoverable in Edison's retail rates, subject
                        only to the CPUC's review of Edison's ongoing
                        administration of the PPAs, as amended.

                15.2.3  Within fifteen (15) days of execution of the Master
                        Definitive Agreement or within such other time period as
                        may be agreed to by Edison, Enron and FPL, Edison will
                        seek CPUC Approval by filing an advice letter of the
                        type and in the manner contemplated by CPUC Decision
                        ("D") No.98-12-066 (83 CPUC 2d 506, Dec. 17, 1998) or by
                        another appropriate filing if it is determined that
                        D.98-12-066 is inapplicable to the Definitive
                        Agreements.

        15.3.   BANKRUPTCY COURT APPROVAL:

                15.3.1  The Parties acknowledge that Bankruptcy Court Approval
                        is a condition precedent to the occurrence of the
                        Satisfaction Date.

                                 DO NOT RELEASE

                        "Bankruptcy Court Approval" means that the Bankruptcy
                        Court has issued an order approving the Definitive
                        Agreements and the PPA Notes that (1) is no longer
                        subject to a motion for re-argument under Bankruptcy
                        Rule 9023 and (2) which, as of the date on which all
                        other conditions precedent to the occurrence of the
                        Satisfaction Date have been satisfied, has not been
                        stayed by the Bankruptcy Court or by another tribunal
                        with jurisdiction in the matter. For purposes of this
                        Section 15.3.1, the Enron Bankruptcy shall be deemed to
                        include, in addition to the matters identified in
                        Section 2.5, the bankruptcies of any Enron affiliated
                        entities, whether mentioned in Section 2.5 or not, that,
                        prior to the Satisfaction Date, are in Chapter 11 or
                        another form of bankruptcy (but only to the extent that
                        such Enron affiliated entities have a property interest,
                        direct or indirect, in one or more of the Projects).
                        Bankruptcy Court Approval shall also include the
                        approval and confirmation by the Bankruptcy Court that
                        the PPA Notes, and Enron Wind Systems' obligations
                        thereunder, without amendment or modification,
                        constitute administrative expenses of the debtor's
                        estate, entitled to priority under Section 507(a)(1) of
                        Chapter 11 of the United States Bankruptcy Code, as
                        amended.

                15.3.2  Enron shall promptly seek Bankruptcy Court Approval upon
                        execution of the Definitive Agreements. Edison, FPL, the
                        PPA Sellers, and their respective affiliates will take
                        such reasonable actions as Enron may request to support
                        such approval and will take no actions in opposition to
                        or inconsistent with the request for Bankruptcy Court
                        Approval.

        15.4.   SEC APPROVAL:

                The occurrence of the Satisfaction Date is not conditioned upon
                SEC approval or on any other action by the SEC.

16.     STANDSTILL; STAY

        16.1.   The standstill provisions set forth in Section 16.2 shall remain
                in effect for a period of thirty (30) days from the Effective
                Date as to any proceeding in which a request for stay has been
                submitted but not yet acted upon, but shall terminate (except
                with respect to the FERC Proceeding as described below in this
                Section 16.1) as to any matter in which the Parties' request for
                stay has been denied in whole or in part. The Parties recognize
                that the procedural schedule in the FERC Proceeding has been
                suspended until January 22, 2003, and intend to seek an
                extension of that suspension so that FERC may consider this
                settlement; as to that proceeding, the

                                 DO NOT RELEASE

                standstill provisions of Section 16.2 shall remain in effect
                unless and until an extension of the suspension is denied.
                Except as to the matters described in Section 16.2, neither the
                standstill nor the pendency of a request for stay pursuant to
                the terms of the MOU shall require any of the Parties hereto to
                refrain from any action in the FERC Proceeding, the SEC
                Proceeding, the Cabazon Litigation or otherwise.

        16.2.   Pursuant to Section 16.1 above for the period specified, the
                Parties agree to:

                16.2.1  Refrain from initiating any new discovery of each other
                        or requiring responses from each other to existing
                        discovery in the SEC Proceeding, the FERC Proceeding and
                        in the Cabazon Litigation;

                16.2.2  Extend day-for-day during the above-referenced period
                        the response dates for all outstanding discovery
                        requests previously served by Edison in the SEC
                        Proceeding and the FERC Proceeding;

                16.2.3  Refrain from taking any further action with respect to
                        Edison's demand for adequate assurances or the Projects'
                        response to such demand.

        16.3.   In connection with the foregoing day-for-day extensions, the
                Parties agree that in no case will any discovery response be due
                sooner than eight (8) Business Days following termination of the
                standstill and that no response to or production requested by
                any motion to compel shall be due sooner than five (5) Business
                Days following termination of the standstill.

        16.4.   Except insofar as any obligation set forth in this paragraph has
                already been satisfied by a Party pursuant to its obligations
                under Section 4(B) of the MOU, the Parties will, as soon as
                practicable, cooperate and use their reasonable best efforts to
                mutually seek a stay of the SEC Proceeding, the FERC Proceeding
                and the Cabazon Litigation pending the obtaining or waiver of
                the Required Regulatory Approvals; provided that the failure to
                obtain any such stay will not, by itself, void the Definitive
                Agreements, or any of them; and provided further that any stays
                implemented pursuant to this paragraph shall terminate
                automatically and without the further action of the Parties upon
                the occurrence, if any, of the Termination Date. The Parties'
                requests for stays in the SEC Proceeding and FERC Proceeding
                shall include a request that all established deadlines in such
                proceedings be extended day-for-day during the periods in which
                the stays are in effect. The Parties' request for stay in the
                Cabazon Litigation shall expressly request a continuance of the
                trial date in that case to a date that is no earlier than 150
                days following the termination, if any, of the stay, as

                well as a commensurate continuance of all then-existing
                deadlines in the litigation.

        16.5.   Should the Court in the Cabazon Litigation decline to stay that
                matter and/or continue the trial date and associated deadlines
                as requested by the Parties, then the plaintiffs in the Cabazon
                Litigation shall promptly dismiss their complaint against Edison
                without prejudice and the parties to the Cabazon Litigation
                shall enter into a tolling agreement for the purpose of tolling
                any applicable statutes of limitations or defenses based on
                similar time bars during the period commencing with the
                dismissal of the complaint in the Cabazon Litigation and ending
                when the plaintiffs therein first become entitled to reinstitute
                their complaint following a failure of the settlement
                memorialized in the Definitive Agreements.

17.     GENERAL PROVISIONS

        17.1.   CONFIDENTIALITY:

                17.1.1  The Parties agree that their negotiations (including the
                        prior negotiations as reflected in the MOU) and the
                        terms of the Definitive Agreements are and shall remain
                        confidential, except insofar as disclosure of the terms
                        and conditions of such negotiations or agreements is
                        necessary to achieve the purposes of such agreements. To
                        that end, voluntary disclosure may be made only as
                        necessary to obtain lender and other power seller or
                        participant or investor approval, FERC Approval, CPUC
                        Approval, Creditors' Committee and Bankruptcy Court
                        Approval, stays of the SEC and FERC Proceedings and the
                        Cabazon Litigation and such other required consents,
                        approvals and notices; provided that:

                        (i)     if an existing confidentiality agreement,
                                protective order or similar obligation is
                                applicable, the Party making disclosure shall
                                notify the receiving party of the confidential
                                nature of the terms and conditions of the MOU
                                and Definitive Agreements and that the existing
                                confidentiality agreement or obligation is
                                applicable thereto;

                        (ii)    if a confidentiality agreement or obligation is
                                not applicable thereto, the Party making
                                disclosure shall use reasonable efforts to first
                                obtain an appropriate confidentiality agreement
                                from the party to whom information concerning
                                the MOU and/or Definitive Agreements is
                                disclosed (and to advise the other Parties if it
                                is not able to do so prior to making
                                disclosure), or

                                     - 19 -


                                  CONFIDENTIAL
                         CONTAINS PRIVILEGED INFORMATION
                                 DO NOT RELEASE

                                in the case of disclosure to a regulatory agency
                                or the Bankruptcy Court, for the purpose of
                                obtaining approval from such agency or Court,
                                seek and use its reasonable best efforts to
                                obtain confidentiality protection from the
                                reviewing agency or the Bankruptcy Court; and

                        (iii)   in the case of any disclosure to a participant
                                or investor in any of the Projects, the Party
                                making disclosure shall be required only to
                                clearly mark all disclosure materials as
                                confidential and to advise the recipient thereof
                                in writing as to the confidential nature of such
                                materials and to further affirmatively state
                                that such materials may not be disclosed to
                                third parties by the recipient.

                17.1.2  The draft of any request for a protective order of, or
                        confidential treatment by, an administrative agency or
                        by the Bankruptcy Court shall be provided to the
                        non-drafting Party sufficiently in advance of filing to
                        permit the non-drafting Party a reasonable opportunity
                        to review and comment upon the draft.

                17.1.3  The Parties acknowledge that the Enron Creditors'
                        Committee and its advisors are already subject to
                        appropriate confidentiality obligations. Edison also
                        understands that, subject to appropriate confidentiality
                        procedures standard for such transactions in the
                        Bankruptcy Court context, disclosure may be made to
                        prospective purchasers (and their potential lenders and
                        advisors) in connection with a sale of the Projects or
                        an interest therein. Notwithstanding the foregoing, in
                        connection with (i) the proposed sale, assignment or
                        other transfer of a Project or of the interest of a
                        Party or its affiliate (or any interest of the Enron
                        Bankruptcy estate) in such Project to a third party, or
                        (ii) the proposed sale of Portland General Electric, a
                        Party shall be entitled to disclose the MOU and
                        Definitive Agreements to a potential purchaser, its
                        affiliates, potential lenders and advisors, provided
                        that the Party making, disclosure shall first obtain an
                        appropriate confidentiality agreement from the potential
                        purchaser. Further, a Party shall not be in breach of
                        its obligations under this Section 17.1 on account of
                        disclosure of any information subject to the provisions
                        of this Section 17.1 to the extent that such information
                        (i) becomes generally available to the public other than
                        as the result of a breach of this Master Definitive
                        Agreement by the disclosing Party; (ii) is obtained from
                        a third

                        party not known to the receiving Party to be prohibited
                        from making disclosure or (iii) is required by
                        applicable law, order, regulation or ruling to be
                        disclosed publicly to, or is publicly disclosed by, a
                        governmental authority, including any court or
                        regulatory agency; and provided, further, that after the
                        Satisfaction Date, the Parties shall be entitled, in the
                        ordinary course of business, to disclose the Definitive
                        Agreements to any legal or financial advisor,
                        accountant, consultant, Project operator or manager,
                        taxing authority or Project property owner or lessor,
                        provided that the Party making such disclosure in the
                        ordinary course of business shall be required to clearly
                        mark all disclosure materials as confidential and to
                        advise the recipient thereof in writing as to the
                        confidential nature of such materials and to further
                        affirmatively state that such materials may not be
                        disclosed to third parties by the recipient.

        17.2.   Effect on PPAs: Except as provided in the Definitive Agreements,
                all provisions of the PPAs shall remain in effect and unchanged.
                Nothing herein shall be read to extend or reduce the term of any
                PPA.

        17.3.   No Waiver: None of the provisions of the Definitive Agreements,
                including this paragraph, shall be considered waived by a Party
                unless such waiver is given in writing. The failure of any Party
                to insist in any one or more instances upon strict performance
                of any of the provisions of the Definitive Agreements or to take
                advantage of any of its rights hereunder shall not be construed
                as a waiver of any such provisions or the relinquishment of any
                such rights for the future, but the same shall continue and
                remain in full force and effect.

        17.4.   Further Agreements: This Master Definitive Agreement shall not
                be amended, changed, modified, abrogated or superseded by a
                subsequent agreement unless such subsequent agreement is in the
                form of a written instrument signed by all of the Parties;
                provided that an instrument which affects only certain of the
                Parties shall be effective if signed by such Parties but shall
                not be effective with respect to the rights and obligations of
                any other Parties.

        17.5.   Entire Agreement; Conflict; Advice of Counsel; Fees and
                Expenses: The Definitive Agreements constitute the entire
                agreement of the Parties concerning the subject matter thereof
                and supercede any and all prior negotiations, correspondence,
                undertakings, and agreements between the Parties, including,
                without limitation, the MOU, concerning the subject matter of
                the Definitive Agreements. Notwithstanding the foregoing, to the
                extent there is a conflict or inconsistency between the
                provisions of this Master Definitive Agreement and the
                provisions of a PPA

                Amendment, the terms of this Master Definitive Agreement shall
                control. The Parties have read the Definitive Agreements, have
                had the advice and assistance of legal counsel in entering into
                them, and have not been influenced to any extent whatsoever by
                any representations or statements made by any Party other than
                those in the Definitive Agreements. The Parties, and each of
                them, shall bear their own attorneys' fees and costs arising
                from or pertaining to (i) the negotiation, preparation and
                implementation of the Definitive Agreements and (ii) the
                obtaining of the Required Regulatory Approvals.

        17.6.   Successors and Assigns: This Master Definitive Agreement shall
                be binding upon and inure to the benefit of the Parties hereto
                and their respective successors and assigns.

        17.7.   Construction: The Definitive Agreements have been drafted by all
                of the Parties and shall not be construed against any Party as
                the sole drafter or pursuant to any other rule of construction.

        17.8.   Governing Law: The Definitive Agreements shall be governed by
                and construed under the laws of the State of California without
                regard to its conflict of laws principles.

        17.9.   Headings: The headings used in the Definitive Agreements are for
                convenience and reference purposes only and do not themselves
                constitute any of the terms of the Definitive Agreements.

        17.10.  No Precedent; Use in Litigation; No Third Party Beneficiaries:
                Each Party agrees that the Definitive Agreements arise from
                unique facts and circumstances and, as such, the various
                provisions of the Definitive Agreements shall not, except as
                expressly provided for herein, be used as evidence relevant to,
                or the basis for disputing the validity or appropriateness of,
                any determination of avoided costs before the FERC, CPUC or any
                court or other judicial or quasi-judicial body, and nothing
                herein may be used as an admission against any Party. Further,
                the Parties do not admit liability as to any of the Claims
                released herein and acknowledge that the Definitive Agreements
                establish no precedents with respect to other parties selling
                pursuant to other power purchase agreements, with respect to
                other power purchase agreements, or with respect to disputes
                other than those that are referenced in this Master Definitive
                Agreement. Except for the purpose of obtaining the Required
                Regulatory Approvals or as otherwise expressly authorized by
                this Master Definitive Agreement, including with respect to
                obtaining a stay of the SEC Proceeding pursuant to Section 16.4,
                no Party will introduce or otherwise use the Definitive
                Agreements or any of their terms or conditions in any judicial
                or administrative proceeding or to influence any governmental
                action, other than for the purpose of effectuating and

        The Parties enter into this Amendment with reference to the following
        facts, among others:

        2.1.    On [___], Edison and Seller or Seller's predecessor in interest

        below), as follows:

        3.1.    Waived Qualifying Facility Requirements. Section 4.4.12 of the
                Contract [revise if applicable QF warranty terms are contained
                in a section other than 4.4.12] is hereby replaced in its
                entirety with the following new Section 4.4.12:

                "4.4.12 Notwithstanding any other provision of this Contract,
                        effective on and after the Satisfaction Date, as defined
                        in Section 4 of Amendment No. [_], the Project shall not
                        be required to satisfy any ownership or size limitation
                        requirements applicable to Qualifying Facilities,
                        including, without limitation, 16 U.S.C. Section
                        796(17)(A)(ii), 16 U.S.C. Section 796(17)(C)(ii) and 18
                        C.F.R. Sections 292.204(a)(1) and 292.206 (collectively,
                        the "Waived QF Requirements"). Notwithstanding the
                        foregoing, and although the Project will no longer be
                        required to comply with the Waived QF Requirements and
                        therefore will no longer be required to be or certify as
                        a Qualifying Facility under the Public Utility
                        Regulatory Policies Act of 1978 ("PURPA") and the
                        regulations of the Federal Energy Regulatory Commission
                        ("FERC") implementing PURPA, the Project will, except
                        for the Waived QF Requirements, continue to generate
                        power for sale to Edison under the Contract in the
                        manner required under 16 U.S.C. Section 796(17)(A)(i),
                        16 U.S.C. Section 796(17)(B), and 16 U.S.C. Section
                        796(17)(C)(i) (but not including, in addition to the
                        Waived QF Requirements, any Qualifying Facility
                        certification requirements) of PURPA and the FERC
                        regulations implementing the foregoing provisions
                        identified in this sentence, 18 C.F.R. Section
                        292.204(b), as wind power production facilities, and
                        further, that with the exception of the Waived QF
                        Requirements, this Contract shall continue to be
                        administered by Edison as a Qualifying Facility
                        contract."

        3.2.    Reduction in Capacity Price. Section 9.1.1.2 [revise if
                applicable capacity terms are contained in a Section other than
                9.1.1.2] of the Contract is hereby amended to add the following
                new subsections (c) and (d):

                "(c)    Notwithstanding Section 9.1.1.2 (b) above, effective for
                        deliveries made beginning at 12:01 a.m. Pacific Time on
                        December 1, 2002 through and including the last day of
                        the Contract Term, the time-differentiated D variable
                        shall be calculated using an annual as-available
                        capacity rate of [the project-specific adjusted $/kw-yr
                        capacity price from Attachment A to the Master
                        Definitive Agreement] in lieu of the rate that would
                        otherwise apply under Section 9.1.1.2(b)."

                "(d)    Promptly after the Satisfaction Date, as defined in
                        Section 4 of Amendment No. [ ], any capacity ---
                        payments previously made by Edison to Seller for
                        deliveries made on and after December 1, 2002 which were
                        based upon the capacity price in effect prior to the
                        occurrence of the Satisfaction Date shall be
                        recalculated using the capacity price as revised
                        pursuant to the foregoing Section 9.1.1.2(c). [revise
                        cross-reference as necessary]. The difference (without
                        interest) between the capacity payment(s) actually made
                        for such deliveries and the payments that would have
                        been made using the adjusted capacity price specified in
                        Section 9.1.1.2(c) shall be applied as a credit to
                        Edison against the next payment due to Seller for both
                        Energy and capacity pursuant to the Contract; provided,
                        however, that if the amount of such credit to Edison
                        exceeds the full amount owing for the first payment due
                        to Seller after the Satisfaction Date, Edison shall take
                        a credit equal to the full amount owing for the first
                        payment due Seller after the Satisfaction Date, and
                        shall apply the remaining balance of the credit as an
                        offset to each successive payment due to Seller by
                        Edison thereafter in the same manner until the credit is
                        fully utilized (all such offsets accruing as of the
                        Satisfaction Date). If the credit owed Edison by Seller
                        has not been fully utilized by the conclusion of three
                        successive billing cycles after the Satisfaction Date,
                        then Edison may, at its option, invoice Seller for the
                        remaining, unutilized portion of the credit, which
                        invoice shall be paid by Seller within ten (10) days of
                        receipt."

        3.3.    Energy Pricing. New Sections 9.3.1 through 9.3.5 [revise
                cross-reference as necessary] are added to the Contract as

                "9.3.1  In the event that the Commission changes the applicable
                        rate for Energy (including, but not limited to, changes
                        to the Commission-approved SRAC rate) that is generally
                        applicable, during any part of the remaining term of the
                        Contract, to those entities owning renewable Qualifying
                        Facilities that signed a Renewable Agreement (as defined

                        by the Parties or otherwise, be the revised rate adopted
                        by the Commission."

                "9.3.2  Nothing herein shall preclude any Party from seeking

                        to such change or proposed change."

                        9.3.2 above, nothing in those sections shall be
                        construed as modifying or diminishing any rights or
                        obligations of the Parties under the Energy rate

                        Rate Period (as those terms are defined in the Renewable
                        Agreement), nor shall anything in Sections 9.3.1 and
                        9.3.2 be construed as conferring upon the Commission any
                        rate setting authority that it does not already possess
                        with respect to the Contract, as amended pursuant to the
                        Renewable Agreement."

                "9.3.4  The term 'SRAC' as used herein shall have the same

        Upon the occurrence of the Satisfaction Date, this Amendment shall
