        This WAIVER AND AMENDMENT AGREEMENT, dated as of September 25, 2002 (this "Agreement"), is made and entered into by Société Générale, as Administrative Agent, Citibank N.A., as Depositary Agent, each of the undersigned Banks and Lender Group Agents (acting in its capacity as a Bank, Related Bank and Lender Group Agent), and GenHoldings I, LLC ("Borrower").

        Reference is made to the Amended and Restated Credit Agreement, dated as of March 15, 2002 (the "Credit Agreement"), among Borrower, Société Générale, as Administrative Agent and a Lead Arranger, Citibank, N.A., as Syndication Agent and a Lead Arranger, the other agents and arrangers listed on the signature pages thereto, JPMorgan Chase Bank, as issuer of the Letters of Credit, the financial institutions from time to time party thereto as lenders, and the other persons party thereto from time to time. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Credit Agreement.

RECITALS

        WHEREAS, an Inchoate NEG Downgrade Event has occurred and is continuing and therefore, pursuant to the proviso to Section 3.15.1(a)(i) of the Credit Agreement, on any date on which Project Costs are due and payable, Borrower is required to make, or cause to be made, Cash Equity Contributions in an amount that, after giving effect to any Alternatively Sourced Equity Contributions then available to pay such Project Costs, is sufficient to pay such Project Costs in an aggregate amount up to the then current Available Equity Commitment; and

        WHEREAS, the parties hereto wish to clarify that Cash Equity Contributions made pursuant to the proviso to Section 3.15.1(a)(i) to the Credit Agreement are not intended to be treated as Alternatively Sourced Equity Contributions by amending the definition of Alternatively Sourced Equity Contributions; and

        WHEREAS, the parties hereto wish to clarify that Borrower will be responsible for the reasonable fees, expenses and disbursements of (a) Luskin, Stern & Eisler LLP which shall serve as special counsel to Administrative Agent and (b) a financial consultant to Administrative Agent, in each case in connection with certain ongoing issues related to the Credit Documents, by amending Section 11.4.1 of the Credit Agreement; and

        WHEREAS, the parties hereto wish to clarify the process pursuant to which disbursements are made from the Construction Account to pay Project Costs under circumstances in which no Borrowing is requested and therefore the parties would like to make clarifying changes to the form of Construction Requisition in order to address such circumstances (including circumstances in which Borrower is making Cash Equity Contributions pursuant to the proviso contained in Section 3.15.1(a)(i) of the Credit Agreement); and

        WHEREAS, to facilitate the making of Equity Contributions by Borrower (specifically Equity Contributions in the form of payments made directly by or on behalf of Borrower for the payment of Project Costs), the parties hereto wish to permit certain Alternatively Sourced Equity Contributions to be credited against the Total Equity Commitment whether or not such amounts have been disbursed from the Construction Account in accordance with Section 4.1.2 of the Depositary Agreement (as required by Section 3.7.5 of the Credit Agreement) so long as the other conditions in Section 3.7 of the Credit Agreement have been met and therefore the parties wish to amend the Credit Agreement to eliminate the requirement that all Alternatively Sourced Equity Contributions must be disbursed in accordance with Section 4.1.2 of the Depositary Agreement; and

C-1

        WHEREAS, due to its failure to provide credit support as required under Section 3.4 of each of the PGET Purchase/Sale Agreements, PGET is in default under each of the PGET Purchase/Sale Agreements; and

        WHEREAS, because each PGET Purchase/Sale Agreement is a Major Project Document and because certain Banks believe (although Borrower does not acknowledge) that each default by PGET described above would reasonably be expected to have a Project Material Adverse Effect on the relevant Project, such Banks believe (although Borrower does not acknowledge) that a Project Inchoate Default under Section 6.1.7 of each Project Company Guaranty and a Project Fundamental Inchoate Default under Section 6.2.6 of each Project Company Guaranty has occurred and is continuing and that, if the default by PGET is not cured within the time specified therefore in each Project Company Guarantee, a Project Event of Default under Section 6.1.7 of each Project Company Guaranty and a Borrower Event of Default under Section 7.1.12 of the Credit Agreement will occur and be continuing (such Project Inchoate Defaults, Project Fundamental Inchoate Defaults, Project Events of Default, and Borrower Event of Default and any Borrower Inchoate Default resulting from the default by PGET described above, the "PGET Defaults"); and

        WHEREAS, Section 4.15.2 of the Millennium Project Company Guaranty requires that Completion of the Millennium Project be achieved on or before the EPC Date Certain which, for the Millennium Project, is August 20, 2002; and

        WHEREAS, because the Millennium Project has not achieved Completion on or before the EPC Date Certain, a Project Inchoate Default exists under Section 6.1.6(e) of the Millennium Project Company Guaranty (the "Millennium Completion Default"); and

        WHEREAS, the Construction Requisition required to be submitted by Borrower in order to request a disbursement of funds from the Construction Account requires Borrower to state, among other things, that no (a) Borrower Inchoate Default or Borrower Event of Default or (b) Project Inchoate Default or Project Event of Default with respect to the Subject Intermediate Holding Companies, Subject Project Company or Subject Project has occurred and is continuing; and

        WHEREAS, with respect to the PGET Defaults and the Millennium Completion Default, Borrower has requested (notwithstanding the fact that Borrower does not acknowledge the PGET Defaults) that, in order to permit disbursements from the Construction Account, the Majority Banks waive the requirements contained in the Construction Requisition, that (a) each Subject Project is reasonably expected to achieve Completion on or before the EPC Date Certain and (b) no (i) Borrower Inchoate Default or Borrower Event of Default or (ii) Project Inchoate Default or Project Event of Default with respect to the Subject Intermediate Holding Companies, Subject Project Company or Subject Project has occurred and is continuing; and

        WHEREAS, pursuant to Section 4.1.2 of the Depositary Agreement, Administrative Agent shall instruct Depositary Agent to make the withdrawals and disbursements requested in a Construction Requisition only so long as no Borrower Event of Default or Disbursement Project Event of Default has occurred and is continuing; and

        WHEREAS, with respect to the PGET Defaults and the Millennium Completion Default, Borrower has requested (notwithstanding the fact that Borrower does not acknowledge the PGET Defaults) that, to permit the making of withdrawals and disbursements requested in a Construction Requisition, the Majority Banks waive the requirement in Section 4.1.2 of the Depositary Agreement that no Borrower Event of Default or Disbursement Project Event of Default has occurred and is continuing; and

        WHEREAS, pursuant to Section 4.2.2 of the Depositary Agreement, Administrative Agent shall instruct Depositary Agent to make the disbursements from the Pre-Completion Revenue Account as specified in an applicable Disbursement Request only so long as (i) no Borrower Event of Default has

occurred and is continuing at the time the disbursements are made and (ii) with respect to the disbursements described in clause First of such Section 4.2.2, no Disbursement Project Event of Default has occurred and is continuing; and

        WHEREAS, with respect to the PGET Defaults and the Millennium Completion Default, Borrower has requested (notwithstanding the fact that Borrower does not acknowledge the PGET Defaults) that, to permit the making of disbursements from the Pre-Completion Revenue Account pursuant to clauses First, Second and Third of Section 4.2.2 of the Depositary Agreement, the Majority Banks waive the requirement that no (i) no Borrower Event of Default has occurred and is continuing at the time the disbursements are made and (ii) with respect to the disbursements described in clause First of such Section 4.2.2, no Disbursement Project Event of Default has occurred and is continuing; and

        WHEREAS, pursuant to Sections 3.7.1 and 3.7.6 of the Credit Agreement, Alternatively Sourced Equity Contributions are not credited against the Total Equity Commitment unless, among other things, (a) no (i) Borrower Inchoate Default or Borrower Event of Default or (ii) Project Event of Default or Project Inchoate Default with respect to the Subject Intermediate Holding Companies, Subject Project Company or Subject Project shall have occurred and be continuing and (b) each Subject Project shall be reasonably expected to achieve Completion on or prior to the EPC Date Certain therefore; and

        WHEREAS, with respect to the PGET Defaults and the Millennium Completion Default, Borrower has requested (notwithstanding the fact that Borrower does not acknowledge the PGET defaults) that, to permit the crediting of Alternatively Sourced Equity Contributions made by or on behalf of Borrower from August 22, 2002 through and including the date which is three Banking Days after the date on which this Agreement becomes effective, the Majority Banks waive the following conditions precedent to the crediting of Alternatively Sourced Equity Contributions: (a) the condition precedent, pursuant to Section 3.7.1 of the Credit Agreement, that no (i) Borrower Inchoate Default or Borrower Event of Default or (ii) Project Event of Default or Project Inchoate Default with respect to the Subject Intermediate Holding Companies, Subject Project Company or Subject Project shall have occurred and be continuing and (b) the condition precedent, pursuant to Section 3.7.6 of the Credit Agreement, that each Subject Project shall be reasonably expected to achieve Completion on or prior to the EPC Date Certain therefore; and

        WHEREAS, the achievement of Completion by an Approved Project is a Credit Event and, pursuant to Section 3.12.2 of the Credit Agreement, it is a condition precedent to each Credit Event that no (a) Borrower Inchoate Default or Borrower Event of Default or (b) Project Inchoate Default or Project Event of Default with respect to the Subject Intermediate Holding Companies, Subject Project Company or Subject Project shall have occurred and be continuing; and

        WHEREAS, with respect to the PGET Defaults and the Millennium Completion Default, for the purpose of the achievement of Completion by the Millennium Project, Borrower has requested (notwithstanding the fact that Borrower does not acknowledge the PGET Defaults) that the Majority Banks waive the requirement that no (a) Borrower Inchoate Default or Borrower Event of Default or (b) Project Inchoate Default or Project Event of Default with respect to the Subject Intermediate Holding Companies, Subject Project Company or Subject Project shall have occurred and be continuing; and

        WHEREAS, pursuant to the second sentence of Section 5.15.1 of each Project Company Guaranty, each Project Company may enter into Permitted Change Orders (as defined in each applicable Project Company Guaranty) only so long as no Project Event of Default or Project Fundamental Inchoate Default has occurred and is continuing; and

        WHEREAS, with respect to the PGET Defaults and the Millennium Completion Default, Borrower has requested (notwithstanding the fact that Borrower does not acknowledge the PGET

C-3

Defaults) that, to permit each Project Company to enter into Permitted Change Orders, the Majority Banks waive the requirement that each Project Company may enter into Permitted Change Orders only so long as no Project Event of Default or Project Fundamental Inchoate Default has occurred and is continuing; and

        WHEREAS, the parties hereto have agreed to make the amendments described below and the Majority Banks are willing to provide the waivers requested by Borrower in accordance with and subject to the terms and conditions hereof.
