Each valuation, determination and demand of REPS specified in this clause (ii) shall be made by REPS without consultation with the Sleeve Provider unless such consultation is sought by REPS, except that:

     (1) if the Sleeve Provider disputes any such valuation, determination or demand, prior to any action taken under paragraphs (2) or (3) below, and prior to the commencement of any further remedial action, REPS shall negotiate with the Sleeve Provider in good faith for one Business Day to resolve any such dispute and upon resolution of such dispute, the applicable valuation, determination or demand shall be adjusted accordingly, with corresponding adjustments to the subsequent requests to the Persons to whom such valuations, determinations or demands apply;

     (2) if the Sleeve Provider disputes any such valuation based on Market Information, prior to any action taken under paragraph (3) below, the Market Information and resulting calculation shall be determined in accordance with Section 12.13 and upon such determination, the applicable valuation shall be adjusted accordingly, with corresponding adjustments to the subsequent requests to the Persons to whom such valuations apply; provided that, until such determination in accordance with Section 12.13, the valuation determined by REPS shall apply;

     (3) to the extent applicable, if after the application of paragraphs (1) and (2) above, the Sleeve Provider in its reasonable discretion determines that (x) more than $15,000,000 in outstanding value of Merrill Collateral remains at any time posted or is requested to be posted in excess of the amount that is required to be posted as determined by REPS (determined, in each case, on aggregate basis across all Persons to whom the Sleeve Provider has such excess posted or has requested posting of Merrill Collateral in an outstanding value of $2,000,000 or more in connection with this Agreement), or (y) more than $5,000,000 in outstanding value of Merrill Collateral remains at any time posted or is requested to be posted to any single Person in excess of the amount that is required to be posted as determined by REPS, then, in either case, if REPS disputes such determination, such determination shall be referred by the parties to the Calculation Agent within three Business Days for resolution, and upon resolution of such dispute the applicable valuation shall apply and REPS shall use its reasonable best efforts to negotiate with, and to the extent applicable, dispute valuations of, or provide updated valuations to each such Person holding excess Merrill Collateral that the Sleeve Provider may direct in accordance with the resolution; provided that in lieu thereof REPS may instead authorize the Sleeve Provider to do so; and provided further that, until resolution of this dispute by the Calculation Agent, the valuation determined by REPS shall apply; and

     (4) to the extent applicable, if after application of paragraphs (1) and (2) above the Sleeve Provider in its reasonable discretion determines that the outstanding value of any single Counterparty’s cash collateral posted or requested to be posted to any Sleeve Obligor as determined by REPS is more than $5,000,000 in deficiency of the amount that is required to be posted as determined by Sleeve Provider, then, if REPS disputes such determination, such determination shall be referred by the parties to the Calculation Agent for within three Business Days, and upon resolution of such dispute the applicable valuation shall apply and REPS shall use its reasonable best efforts to negotiate with, and to the extent applicable, dispute valuations of, or provide updated valuations to each such Counterparty that the Sleeve Provider may direct in accordance with the resolution; provided that in lieu thereof REPS may instead authorize the Sleeve Provider to do so; and provided further that, until resolution of this dispute by the Calculation Agent, the valuation determined by REPS shall apply .

The Sleeve Provider shall notify NRG, promptly upon receipt from any beneficiary or recipient of an ML Guarantee or any secured party to which the Sleeve Provider has provided collateral pursuant to Section 2 (whether an ML Guarantee, posted cash collateral, surety bond, letter of credit or other collateral or credit support, “Merrill Collateral” or “ML Collateral”) of any demand for payment under such ML Collateral or any Collateral Foreclosure thereon or of any notice of default. The Sleeve Provider shall notify NRG of the Dollar amount paid by the Merrill Parties as a result of such demand or the Dollar amount of Merrill Collateral relating to such Collateral Foreclosure, as applicable, and the date on which payment was made by a Merrill Party in respect of such demand or the date on which such Collateral Foreclosure occurred, as applicable (any such date, a “Capital Outlay Date”).

NRG hereby unconditionally and irrevocably promises to pay to the Sleeve Provider, on behalf of the applicable Merrill Party, the entire outstanding Dollar amount of each payment on behalf of the Sleeve Obligors by the ML Guarantee Provider or the Sleeve Provider arising from each demand for payment under Merrill Collateral or payment on behalf of the Sleeve Obligors by the Sleeve Provider arising from each Collateral Foreclosure of ML Collateral and the entire outstanding Dollar amount of any ML Collateral that is not returned by any person to the Merrill Parties for any reason (including, any bankruptcy or insolvency of the applicable counterparty) within one Business Day of the time required by the terms of the applicable Counterparty Document or other applicable arrangement pursuant to which such Merrill Collateral was posted to such person (each, a “Draw Reimbursement Obligation”), notwithstanding the identity of the beneficiary or recipient of any Merrill Collateral, and without presentment, demand, protest or other formalities of any kind. Each such Draw Reimbursement Obligation shall mature on the Business Day following the date the Sleeve Provider delivers notice to NRG of the related Capital Outlay Date as provided in Section 3.01 (the “Notice Date”); provided that, in the event that, on or prior to the Business Day following the Notice Date, NRG delivers to the Sleeve Provider in good faith a written notice referred to in Section 8.02(b) or (c) predicated upon (i) failure to pay under any ML Guarantee after demand by the beneficiary complying with the terms and conditions of the ML Guarantee or (ii) the breach of a Merrill Party of its obligations under Section 2.01 or any Credit Support Agreement, such Draw Reimbursement Obligation shall mature and be payable on the earliest of (A) the date that the notice to the Sleeve Provider is withdrawn, (B) the date the underlying failure related to the Draw Reimbursement Obligation is cured, (C) the date that the remedies under Section 9.02 with respect to such failure have been resolved, mutually concluded, or finally determined by a court of competent jurisdiction, or (D) January 29, 2010 (any Reimbursement Obligation subject to the foregoing proviso, a “Deferred Draw Reimbursement Obligation”).

          Notwithstanding any payment of a Draw Reimbursement Obligation NRG makes as required in this Section 3.02, NRG does not by making such payment waive any rights under Sections 8.02 and 9.02 against a Merrill Party related to the applicable Draw Reimbursement Obligation, subject to the limitations in Section 9.04.

     (e)  this Reimbursement Guaranty and the obligations of the Reimbursement Guarantors hereunder shall be valid and enforceable and shall not be subject to any reduction, limitation, impairment, discharge or termination for any reason (other than payment in full of the Guaranteed Obligations), including the occurrence of any of the following, whether or not any Reimbursement Guarantor shall have had notice or knowledge of any of them: (i) any failure or omission to assert or enforce or agreement or election not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or demand or any right,

power or remedy (whether arising under the Transaction Documents, at law, in equity or otherwise) with respect to the Guaranteed Obligations or any agreement relating thereto, or with respect to any other guaranty of or security for the payment of the Guaranteed Obligations; (ii) any rescission, waiver, amendment or modification of, or any consent to departure from, any of the terms or provisions (including provisions relating to events of default) hereof, any of the other Transaction Documents or any agreement or instrument executed pursuant thereto, or of any other guaranty or security for the Guaranteed Obligations, in each case whether or not in accordance with the terms hereof or such Transaction Document or any agreement relating to such other guaranty or security; (iii) the Guaranteed Obligations, or any agreement relating thereto, at any time being found to be illegal, invalid or unenforceable in any respect; (iv) any Merrill Party’s consent to the change, reorganization or termination of the corporate structure or existence of NRG or any of its Subsidiaries and to any corresponding restructuring of the Guaranteed Obligations; (v) any failure to perfect or continue perfection of a security interest in any collateral which secures any of the Guaranteed Obligations; and (vi) any other act or thing or omission, or delay to do any other act or thing, which may or might in any manner or to any extent vary the risk of any Reimbursement Guarantor as an obligor in respect of the Guaranteed Obligations.

          11.04. Waivers by Reimbursement Guarantors. Each Reimbursement Guarantor hereby waives, for the benefit of the Merrill Parties: (a) any right to require any Merrill Party, as a condition of payment or performance by such Reimbursement Guarantor, to (i) proceed against NRG, any other guarantor (including any other Reimbursement Guarantor) of the Guaranteed Obligations or any other Person, (ii) proceed against or exhaust any security held from NRG, any such other guarantor or any other Person, (iii) proceed against or have resort to any balance of any Posted Collateral or credit on the books of any Merrill Party in favor of NRG or any other Person, or (iv) pursue any other remedy in the power of any Merrill Party whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability of NRG or any other Reimbursement Guarantor including any defense based on or arising out of the lack of validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument relating thereto; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms hereof, to the extent the same may be waived, (ii) the benefit of any statute of limitations affecting such Reimbursement Guarantor’s liability hereunder or the enforcement hereof, and (iii) promptness, diligence and any requirement that any Merrill Party protect, secure, perfect or insure any security interest or lien or any property subject thereto; (e) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance hereof, notices of default hereunder or under any agreement or instrument related thereto, notices of any renewal, extension or modification of the Guaranteed Obligations or any agreement related thereto, notices of any extension of credit to NRG and notices of any of the matters referred to in Section 11.04; and (f) any other defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof.

          11.05. [Intentionally Deleted].

          11.06. [Intentionally Deleted].

          11.07. Continuing Reimbursement Guaranty. This Reimbursement Guaranty is a continuing guaranty and shall remain in effect until all of the Guaranteed Obligations shall have been paid in full (subject to reinstatement as provided in Section 11.10(b) below).

          11.08. Authority of Reimbursement Guarantors or NRG. It is not necessary for any Merrill Party to inquire into the capacity or powers of any Reimbursement Guarantor or NRG or the officers, directors or any agents acting or purporting to act on behalf of any of them.

Any Reimbursement Guaranty may be made to NRG or continued from time to time, without notice to or authorization from any Reimbursement Guarantor regardless of the financial or other condition of NRG at the time of any such grant or continuation. No Merrill Party shall have any obligation to disclose or discuss with any Reimbursement Guarantor its assessment, or any Reimbursement Guarantor’s assessment, of the financial condition of NRG. Each Reimbursement Guarantor has adequate means to obtain information from NRG on a continuing basis concerning the financial condition of NRG and its ability to perform its obligations under the Transaction Documents, and each Reimbursement Guarantor assumes the responsibility for being and keeping informed of the financial condition of NRG and of all circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations. Each Reimbursement Guarantor hereby waives and relinquishes any duty on the part of any Merrill Party to disclose any matter, fact or thing relating to the business, operations or conditions of NRG now known or hereafter known by any Merrill Party.

          11.10. Bankruptcy, etc.

          (a) Each Reimbursement Guarantor acknowledges and agrees that any interest on any portion of the Guaranteed Obligations which accrues after the commencement of any bankruptcy, reorganization or insolvency case or proceeding (or, if interest on any portion of the Guaranteed Obligations ceases to accrue by operation of law by reason of the commencement of such case or proceeding, such interest as would have accrued on such portion of the Guaranteed Obligations if such case or proceeding had not been commenced) shall be included in the Guaranteed Obligations because it is the intention of Reimbursement Guarantors and Merrill Parties that the Guaranteed Obligations which are guaranteed by Reimbursement Guarantors pursuant hereto should be determined without regard to any rule of law or order which may relieve NRG of any portion of such Guaranteed Obligations. Reimbursement Guarantors will permit any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit of creditors or similar person to pay the Merrill Parties, or allow the claim of the Merrill Parties in respect of, any such interest accruing after the date on which such case or proceeding is commenced.

          (b) In the event that all or any portion of the Guaranteed Obligations are paid by NRG or a Reimbursement Guarantor, the obligations of Reimbursement Guarantors hereunder

shall continue and remain full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) are rescinded or recovered directly or indirectly from any Merrill Party as a preference, fraudulent transfer or otherwise, and any such payments which are so rescinded or recovered shall constitute Guaranteed Obligations for all purposes hereunder.

          12.13. Certain Dispute Resolution Procedures.

Market Information that the Parties have agreed are not in dispute; and (B) calculating the component that is in dispute by seeking four actual quotations at mid market from reference market makers, and taking the arithmetic average of those obtained; provided that if such number of quotations are not available for a particular component, then fewer than such number of quotations may be used for such component; and if no quotations are available for a particular component, then the Calculation Agent shall use its own calculations for that component.
