          3.01. Notice of Payment on ML Guarantee or Collateral Foreclosure. The Sleeve Provider shall notify REPS, 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 Article 2 (whether a 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 REPS 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”).

          3.02. Repayment of Draw Reimbursement Obligations. REPS 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 Reliant Retail 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 Reliant Retail 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 REPS 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, REPS 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, (D) the date that the Working Capital Facility matures (whether on the Maturity Date under, and as defined in, the Working Capital Facility, by acceleration or otherwise), or (E) November 1, 2010 (any Reimbursement Obligation subject to the foregoing proviso, a “Deferred Draw Reimbursement Obligation”).

Notwithstanding any payment of a Draw Reimbursement Obligation REPS makes as required in this Section 3.02, REPS 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.

          3.03. Interest.

          (a) (i) REPS hereby unconditionally promises to pay to the Sleeve Provider, when due and payable in accordance with Section 3.03(d):

     (B) interest accruing at a rate per annum equal to the LIBO Rate (as defined in the Working Capital Facility and incorporated by reference in accordance with Section 3.03(a)(ii)) plus 5.875% on the unpaid Dollar amount of each Deferred Reimbursement Obligation for the period from and including the Business Day following the related Notice Date to but excluding the date the Dollar amount of such Deferred Reimbursement Obligation shall be paid in full.

          (c) with respect to each month in which Exposure exceeds the Maximum Permitted Exposure, the Excess Exposure Fee for such month (which shall be in addition to the Monthly Sleeve Fee and the Additional Sleeve Fee for such month), which shall be payable promptly, and in event within three Business Days of notice from the Sleeve Provider to REPS that such Excess Exposure Fee is due and payable; and

          (d) with respect to the month of April 2009, the “Monthly Sleeve Fee” (as defined in the Existing CSRA) in respect of such month (the “April 2009 Sleeve Fee”), which amount shall be due and payable and calculated in accordance with the relevant provisions of the Existing CSRA (as if the Existing CSRA remained in effect); provided that the Parties acknowledge and agree that no “True-Up Sleeve Fee Amount” or other adjustment to the April 2009 Sleeve Fee or any other sleeve fees previously paid under the Existing CSRA shall be due and payable.

All Monthly Sleeve Fee, Additional Sleeve Fee and Excess Exposure Fee or any portion of any thereof shall not be refundable under any circumstances. In addition, REPS hereby unconditionally promises to pay to the Sleeve Provider from time to time on demand interest accruing at a rate per annum equal to the Post-Default Rate (as in effect from time to time) on the aggregate amount of any Monthly Sleeve Fee, Additional Sleeve Fee or Excess Exposure Fee that is not paid in full when due.

on the Credit Sleeve Termination Date a make-whole payment in an amount equal to $10,000,000 (the “Make-whole Payment”); provided that, no Make-whole Payment will be due if, following the occurrence on or prior to January 1, 2010 of any Sleeve Provider Event of Default under Section 8.02(b), (f), (g) or (h), the Reliant Retail Obligors shall have declared the Unwind Start Date and be actively pursuing the engagement of a Replacement Sleeve Provider. The Make-whole Payment or any portion thereof shall not be refundable under any circumstances.

          (a) Payments by Reliant Retail Obligors. Except to the extent otherwise provided herein, all payments in respect of Reimbursement Obligations, interest, Monthly Sleeve Fees, Additional Sleeve Fees, any Excess Exposure Fee, Make-whole Payment and other amounts to be made by the Reliant Retail Obligors under this Agreement, and, except to the extent otherwise provided therein, all payments to be made by the Reliant Retail Obligors under any other Transaction Document, shall be made in Dollars, in immediately available funds, without deduction, set-off or counterclaim to the Sleeve Provider at the account designated on Schedule 3.06(a) or any other account designated in writing by the Sleeve Provider to REPS not less than five Business Days before any payment is made, not later than 3:00 p.m., New York City time, on the date on which such payment shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day).

          (d) There are no facts, circumstances or conditions known to the Reliant Retail Obligors arising out of or relating to the operations or ownership of the Reliant Retail Obligors or of the property owned, operated or leased by the Reliant Retail Obligors that are not specifically included in the financial information furnished to the Sleeve Provider that could be reasonably expected to result in any Environmental Liabilities that could reasonably be expected to have a Material Adverse Effect, except for such liabilities that are (i) covered by environmental liability insurance, (ii) subject to an indemnity from any Governmental Authority, or (iii) subject to an indemnity satisfactory to REPS from a Person that is not an Affiliate of REPS that REPS has determined in good faith is appropriately credit worthy in relation to the potential amount of such liabilities.

          (e) As of the Third A&R Date, to the knowledge of the Reliant Retail Obligors, no environmental Lien has attached to any property owned by the Reliant Retail Obligors and, to the knowledge of the Reliant Retail Obligors, no facts, circumstance or conditions exist that could, individually or in the aggregate, reasonably be expected to result in an environmental Lien that would have a Material Adverse Effect.

          5.11. Taxes. The Reliant Retail Obligors have filed all Federal, state and other material tax returns and reports required to be filed after giving effect to applicable extensions, except for tax returns or reports the failure of which to timely file could not reasonably be expected to have a Material Adverse Effect, and have paid all Federal, state and other material taxes, assessments, fees and other governmental charges levied or imposed upon them or their properties, income or assets otherwise due and payable, except those which are being contested in good faith by appropriate proceedings diligently conducted and for which adequate reserves have been provided in accordance with GAAP.

          (a) The Reliant Retail Obligors shall maintain in effect the Risk Management Policy with respect to Approved Markets. The Reliant Retail Obligors may waive the Risk Management Policy with respect to Approved Markets with respect to individual actions, provided that any such waiver shall require prior written approval of the Sleeve Provider, which shall not be unreasonably withheld or delayed, and shall be responded to in any event within three Business Days. The Reliant Retail Obligors may amend or otherwise modify in general the Risk Management Policy with respect to Approved Markets, provided that REPS shall promptly provide to the Sleeve Provider copies of final requests for such general amendments or modifications to the Risk Management Policy promptly after providing such final requests to senior management, and before becoming effective such amendments or modifications shall be approved by the Sleeve Provider, which approval shall not be unreasonably withheld or delayed, and shall be responded to in any event within three Business Days.

          (b) The Reliant Retail Obligors shall comply with the Risk Management

Policy to the extent required by the following:

     (i) If there shall occur any violation of any Risk Limit as set forth in any Risk Limit Report, the Reliant Retail Obligors shall have three Business Days to cure the same after notice thereof delivered to or received from the Sleeve Provider or, with respect any violation under clause (a) of the definition of Risk Limit, any Responsible Officer or other executive officer of REPS obtaining knowledge of such occurrence; provided that if at any time the mark-to-market loss on position(s) in violation of the Risk Limits exceeds $25,000,000, the Reliant Retail Obligors shall have only one Business Day after the date of the delivery or receipt of notice or, with respect to any violation under clause (a) of the definition of Risk Limit, knowledge to cure the same such that the position(s) in violation do not exceed such threshold (however, if such threshold is exceeded during the last day of any three Business Day cure period, such three Business Day cure period shall be extended through the following Business Day such that the Reliant Retail Obligors shall have the fourth Business Day to cure such violation). If cure is not effected within such three (or four) Business Day period, then as the Sleeve Provider’s sole remedy with respect to such violation, other than under Section 6.13(b)(ii), the Sleeve Provider shall have the right to enter into hedges with REPS to effect the cure at prices consistent with the prices the Sleeve Provider would use in transactions with third parties at the applicable times and in the applicable volumes. In exercising such right, Sleeve Provider will use the same standard of care as Sleeve Provider uses in conducting transactions to correct risk policy violations under Sleeve Provider’s risk policies.

     (ii) In addition to the rights of Sleeve Provider under Section 6.13(b)(i), if there shall occur any Level III Violation, after providing notice thereof to Sleeve Provider in accordance with Section 6.13(a), at the Sleeve Provider’s request the Reliant Retail Obligors will take the following actions:

          (A) Notify immediately the Chief Executive Officer, Chief Financial Officer, Chief Risk Officer and Controller of the Level III Violation;

          (B) Present to the Merrill Parties within five Business Days a Working Plan that has been approved by the Chief Executive Officer;

          (C) Present to Merrill Parties within 30 Business Days a Remediation Plan that has been approved by the Chief Executive Officer. The Merrill Parties shall have two Business Days after receipt of such Remediation Plan to consult with the Reliant Parties and review and agree upon the same. If the Merrill Parties and the Reliant Retail Obligors do not mutually agree on the Remediation Plan at the end of such two Business Day period, then a third-party evaluator chosen from the list set forth in Schedule 1.01(a) shall be engaged to mediate promptly the matters in dispute; and

          (D) Submit the Remediation Plan to the Audit Committee promptly after its determination in accordance with paragraph (C) above. If the Audit Committee does not approve the Remediation Plan within six Business Days after submission, the Reliant Retail Obligors shall consult with the Merrill Parties and make reasonable

modifications to the Remediation Plan based upon comments from the Audit Committee, and resubmit the same within ten Business Days after the end of such six Business Day period.

It shall be a Reliant Event of Default (a “Risk Management Event of Default”) if the Reliant Retail Obligors (1) do not comply with the process provided for in Section 6.13(b)(ii)(A) through (D), and the same is not cured within two Business Days, or (2) if the resubmitted Remediation Plan described in Section 6.13(b)(ii)(D) above is not implemented by the Reliant Retail Obligors in all material respects. A Risk Management Event of Default shall be the sole Reliant Events of Default or Defaults with respect thereto for any non-compliance with the Risk Management Policy or breach of Section 6.13(b).

          6.14. Employees. Have sufficient officers and employees that, taken together with the services provided under arm’s length service contracts (including the NRG Parent Service Agreement and the Transition Services Agreement, if then in effect), RERH Holdings and its Subsidiaries can run the Retail Energy Business in a manner consistent with the business operations of the Retail Energy Business as of the Third A&R Date and provide the Retail Provided Services in accordance with the NRG Parent Services Agreement.

          6.15. Information Technology Systems. Own or have access to (through arm’s length contracts including the IT Service Agreement, the Transition Services Agreement, the NRG Parent Services Agreement and the IP License Agreement, if the same are then in effect), at all times, the Information Technology Systems necessary to run the Retail Energy Business, including Information Technology Systems providing capabilities consistent with the arrangements in place for the Retail Energy Business as of the Third A&R Date and provide the Retail Provided Services in accordance with the NRG Parent Services Agreement.

          6.16. Marks. Own the Marks necessary to run the Retail Energy Business using the “Reliant” name consistent with the arrangements in place for the Retail Energy Business as of the Third A&R Date.

          6.17. NRG Parent Services Agreement.

     (a) Promptly upon receipt, furnish to the Sleeve Provider the Corporate Cost Center Allocation under the NRG Parent Services Agreement for each Fiscal Quarter contemplated by Section 5.1(b) of the NRG Parent Services Agreement, including the cost center basis for such Corporate Cost Center Allocation as between the cost centers referred to on Exhibit C to the NRG Parent Services Agreement; provided that at the option of REPS, certain of the cost centers may be reported on a consolidated basis. The Reliant Retail Obligors shall not approve any change in the methodology for allocation of the costs and expenses giving rise to the Corporate Cost Center Allocation referred to on Exhibit B to the NRG Parent Services Agreement proposed by NRG Parent without giving 30 days prior written notice to the Sleeve Provider and, in the event NRG Parent proposes to change the methodology for allocation of such costs and expenses in a manner materially adverse to the Reliant Retail Obligors (it being expressly understood that an increase is not in and of itself “materially adverse”), the Reliant Retail Obligors shall not

approve such change without the approval of the Sleeve Provider, such approval not to be unreasonably withheld or delayed.

     (b) Commencing with the 2010 Fiscal Year, consult with the Sleeve Provider in the event that the Corporate Cost Center Allocation for any Fiscal Year reflects an increase of more than 5% over the prior Fiscal Year. In such case, and to the extent that third-party suppliers could reasonably be expected to provide all or certain of the Administrative Services provided under the NRG Parent Services Agreement on a more cost effective basis than under the NRG Parent Service Agreement (taking into account all relevant factors including demobilization and transition costs), REPS shall solicit as promptly as practicable, through an industry standard request for proposals, bids for comparable administrative services from recognized third-party service providers for those Administrative Services determined not to be cost effective under the NRG Parent Services Agreement. Upon receipt and review of the bids procured, REPS shall choose the service provider best able to provide the administrative services required (and shall furnish a written assessment of the bids provided to the Sleeve Provider, together with written support for any bids proposed to be accepted that are not the lowest cost bids). REPS shall promptly deliver the notice required under Section 3.4(b) of the NRG Parent Services Agreement with respect to any Administrative Services that are to be performed by third-party service providers in accordance with the foregoing.

          6.18. Obligation to Post Collateral to Sleeve Provider.

     (a) Upon receipt of any Required Equity Contribution, REPS shall post such Required Equity Contribution in cash to the Sleeve Provider.

     (b) The Sleeve Provider hereby unconditionally promises to pay to REPS, with respect to any Posted Collateral which is cash, interest accruing at a rate per annum equal to the Federal Funds Rate, for each day, on the Dollar amount of such collateral posted as cash held by the Sleeve Provider on such day (which has not been theretofore applied or used by the Merrill Parties to satisfy any Draw Reimbursement Obligation or any other Secured Obligation or otherwise returned to REPS). Such interest shall be payable monthly in arrears within two Business Days following the last day of each month and on the Credit Sleeve Termination Date.

     (c) The Sleeve Provider will, notwithstanding Section 9-207 of the New York Uniform Commercial Code, have the right to (i) sell, pledge, rehypothecate, assign, invest, use, commingle or otherwise dispose of, or otherwise use in its business any Posted Collateral it holds, free from any claim or right of any nature whatsoever of the Reliant Retail Obligors, including any equity or right of redemption by the Reliant Retail Obligors and (ii) register any Posted Collateral in the name of the Sleeve Provider, its custodian or a nominee for either. Upon the occurrence and continuance of a Reliant Event of Default, the Merrill Parties shall have, in addition to all other rights and remedies in favor of a secured party existing at law or equity, the rights and remedies of a secured party under the UCC with respect to the Posted Collateral, including the right to apply Posted Collateral in satisfaction of the Secured Obligations.

     (d) Promptly following the occurrence of the Credit Sleeve Termination Date (or concurrently therewith to the extent that the Reliant Retail Obligors have made arrangements

satisfactory to the Merrill Parties to cause the occurrence of the Credit Sleeve Termination Date in accordance with Section 6.19(b) below) and the date on which all other Secured Obligations have been paid or satisfied in full (other than indemnities and any similar obligations of the Reliant Retail Obligors not then due and payable and that expressly survive termination of this Agreement and the other Transaction Documents), the Merrill Parties shall return all Posted Collateral, together with any accrued interest, to REPS which has not been theretofore applied and will not be concurrently applied in connection with arrangements made in accordance with Section 6.19(d) below or otherwise used by the Merrill Parties to satisfy any Draw Reimbursement Obligation or any other Secured Obligation or otherwise returned to REPS.

          6.19. Credit Sleeve Termination Date and Transition Period.

     (a) The Reliant Retail Obligors shall cause the Credit Sleeve Termination Date to occur on or prior to November 1, 2010. Except as expressly provided in clause (d) below, the “Credit Sleeve Termination Date” shall not occur until the date on which all Merrill Collateral, including all ML Guarantees, posted by the Merrill Parties have been returned to the Merrill Parties and the Merrill Parties have been legally discharged from all obligations in respect of the transactions contemplated hereby and all ML Guarantees have been terminated, and on which all other obligations owed to the Merrill Parties hereunder and under the other Transaction Documents have been paid and satisfied in full (other than indemnities and any similar obligations of the Reliant Retail Obligors not then due and payable and that expressly survive termination of this Agreement and the other Transaction Documents).

     (b) The Reliant Retail Obligors shall, on or prior to the Transition Start Date, inform each Accepted Counterparty and each other beneficiary of any ML Collateral, including each beneficiary of any ML Guarantee, that on November 1, 2010 (or such earlier date as the Reliant Retail Obligors may elect to cause the “Credit Sleeve Termination Date”, such date, the “Transition End Date”), that the Reliant Retail Obligors desire for such Accepted Counterparty or other beneficiary, as the case may be, to release all ML Collateral, including each ML Guarantee, and to discharge all future obligations of the Merrill Parties to provide or post any future collateral or ML Guarantee, in exchange for alternate collateral or other arrangements to be negotiated between the Reliant Retail Obligors and such Accepted Counterparty or other beneficiary, in each case, to be effective on the Transition End Date. During the Transition Period, the Reliant Retail Obligors agree to use all commercially reasonable efforts to effect the release and discharge of all ML Collateral on the Transition End Date in accordance with the foregoing sentence, and shall on or prior to the second Business Day of each calendar week during the Transition Period, provide to the Merrill Parties a reasonably detailed summary of the progress of negotiations with each Accepted Counterparty and each other beneficiary in connection with the Transition End Date. Nothing in this clause (b), or any action or inaction of any Accepted Counterparty or any other beneficiary of any ML Collateral, shall relieve the Reliant Retail Obligors of the obligation to cause the Credit Sleeve Termination Date to occur in accordance with clause (a) above.

     (c) Without limiting the generality of clause (b) above, with respect to each Exchange Traded Contract and each corresponding Mirror OTC Contract that is held by the Reliant Retail Obligors and the Merrill Parties on the Transition End Date, the Reliant Retail Obligors will, or

will cause an Affiliate to, (i) enter into a transaction on ICE or NYMEX, as applicable, to transfer the Sleeve Provider’s position in such Exchange Traded Contract to such Reliant Retail Obligor or such Affiliate and (ii) close-out each related Mirror OTC Contract (which may be through novation of the Sleeve Provider’s position under such Mirror OTC Contract to such Affiliate), in each case, at no cost or expense to the Merrill Parties. Concurrently with the completion of the foregoing transfers and novations, the Merrill Parties shall be legally discharged from all obligations under such transactions, the Merrill Parties shall have received the return of all variation margin and all other ML Collateral posted in connection therewith, and all related ML Guarantees shall be terminated; provided that nothing in this clause (c) shall relieve the Reliant Retail Obligors of the obligation to cause the Credit Sleeve Termination Date to occur in accordance with clause (a) above.

     (d) If, notwithstanding the use of all commercially reasonable efforts by the Reliant Retail Obligors to effect a full release of the Merrill Parties in accordance with clauses (a) and (b) above, the Merrill Parties remain obligated in respect of any Accepted Trades on November 1, 2010 under which the aggregate exposure of all such Accepted Trades (expressed in BCFe) is equal to or less than 30 BCFe (calculated based on the absolute volume of such Accepted Trades, whether a buy or a sell transaction), then the Reliant Retail Obligors may elect to satisfy their obligations to release and discharge the Merrill Parties in respect of such Accepted Trades by (i) posting (and maintaining to the extent required below) cash collateral in an amount at least equal to the Cash Coverage Amount and (ii) posting (and maintaining to the extent required below) cash collateral or providing one or more letters of credit satisfactory to the Merrill Parties or a guarantee by a Person with at least an Investment Grade Credit Rating, for an amount at least equal to the Additional Coverage Amount (the “Clean-Up Option”). At any time and from time to time after any such posting or other arrangements have been made, the Reliant Retail Obligors shall be required to post additional cash collateral to the extent that the Merrill Parties reasonably determine that the aggregate amount of cash collateral and other support then posted is insufficient to exceed the actual liabilities of the Merrill Parties at any time following the exercise of such Clean-Up Option. Until such time as all Merrill Collateral, including all ML Guarantees, posted by the Merrill Parties have been returned to the Merrill Parties and the Merrill Parties have been legally discharged from all obligations in respect of the transactions contemplated hereby and all ML Guarantees have been terminated, and on which all other obligations owed to the Merrill Parties hereunder and under the other Transaction Documents have been paid and satisfied in full (other than indemnities and any similar obligations of the Reliant Retail Obligors not then due and payable and that expressly survive termination of this Agreement and the other Transaction Documents) and on which all other Secured Obligations have been paid or satisfied in full (other than indemnities and any similar obligations of the Reliant Retail Obligors not then due and payable and that expressly survive termination of this Agreement and the other Transaction Documents), the Merrill Parties shall be entitled to retain and apply all such posted collateral and any other support in satisfaction of the obligations of the Reliant Retail Obligors.

          6.20. IT Trust Transfer and Allocation Plan. Shall (a) implement the IT Trust Transfer and Allocation Plan as promptly as practicable in accordance with its terms pursuant to documentation in form and substance satisfactory to the Sleeve Provider, (b) cause modifications of the Transition Services Agreement contemplated by Section 3.2(f) of the

Purchase and Sale Agreement in form and substance satisfactory to the Sleeve Provider (i) necessary to implement the IT Trust Transfer and Allocation Plan and (ii) as may be required to ensure that at all times the Reliant Retail Obligors have access to Information Systems Technology necessary to run the Retail Energy Business (including providing the Retail Provided Services), including Information Technology Systems providing capabilities consistent with the arrangements in place for the Retail Energy Business as of the Third A&R Date and (c) following the complete implementation of the IT Trust Transfer and Allocation Plan, dissolve the IT Trust in a manner reasonably satisfactory to the Sleeve Provider.

          Section 7. Negative Covenants. From the Third A&R Date until the Credit Sleeve Termination Date, the Reliant Retail Obligors shall not, and shall cause their Subsidiaries not to:

          7.01. Liens. Create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind on any asset now owned or hereafter acquired, except Permitted Liens.

     (a) Indebtedness of RERH Holdings and the Reliant Retail Obligors under this Agreement, if any, and the Working Capital Facility;

     (b) intercompany Indebtedness (i) between or among Reliant Retail Obligors and (ii) Indebtedness of Subsidiaries of RERH Holdings that are not Reliant Retail Obligors to Reliant Retail Obligors; provided that (A) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than RERH or any Subsidiary, and (B) any sale or other transfer of any such Indebtedness to a Person that is not RERH or any Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness by RERH or such Subsidiary, as the case may be, that was not permitted by this clause;

     (c) Indebtedness of RERH Holdings or any of its Subsidiaries in respect of workers’ compensation claims, self-insurance obligations, performance and surety bonds provided by RERH Holdings or a Subsidiary in the ordinary course of business;

     (d) Indebtedness of RERH Holdings or any of its Subsidiaries arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days;

     (e) Indebtedness arising from agreements of RERH Holdings or a Subsidiary providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or Equity Interests of a Subsidiary of RERH Holdings; provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds (including non-cash proceeds) actually received by RERH Holdings and/or such Subsidiary in connection with such disposition;

     (f) Additional Indebtedness of Subsidiaries of RERH Holdings or purchase money obligations in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, not to exceed $20,000,000, the proceeds of which are used for, or assumed in connection with, general corporate purposes of RERH or any of its Subsidiaries, including for any capital expenditures; provided that (i) except for regularly scheduled amortization payments in any year not exceeding 5% of original principal amount of such Indebtedness, any Indebtedness incurred in reliance on this clause (f) shall mature no earlier than 6 months after the Credit Sleeve Termination Date and (ii) the terms of all such Indebtedness shall permit prepayment thereof at any time from any Person or source at par without any premium or penalty;

     (g) the Guarantee by (i) Reliant Retail Obligors of Indebtedness of Reliant Retail Obligors that is otherwise permitted by this Section 7.03, (ii) Reliant Retail Obligors of Indebtedness of Subsidiaries of RERH Holdings that are not Reliant Retail Obligors that is otherwise permitted by this Section 7.03 and (iii) RERH of the obligations of REES under the Amended and Restated Power Purchase Agreement between REES and FPL Upton Wind II, L.P. dated May 30, 2003, as in effect on the date hereof;

          (i) so long as no Reliant Default exists or would result therefrom, (A) any Subsidiary of RERH Holdings may consolidate or merge with or into any one or more other Subsidiaries of RERH Holdings; provided that in the event that a Subsidiary of RERH Holdings is a Reliant Retail Obligor, such Subsidiary may only consolidate or merge with or into another Subsidiary of RERH Holdings that is a Reliant Retail Obligor, and (B) any Person may be merged with or into any Subsidiary of RERH Holdings if the resulting entity is a Wholly Owned Subsidiary of RERH Holdings, provided that the provisions of Section 6.11(a) are complied with in connection with any such transaction involving a Subsidiary of RERH Holdings that is not a Reliant Retail Obligor; and

          (ii) so long as no Reliant Default exists or would result therefrom, any Subsidiary of RERH Holdings may sell, transfer, assign, convey, lease or otherwise dispose of any or all of its assets to any one or more other Subsidiaries of RERH Holdings, provided that the provisions of Section 6.11(a) are complied with in connection with any such transaction involving a Subsidiary of RERH Holdings that is not a Reliant Retail Obligor.

          (b) In addition, the Reliant Retail Obligors shall not, nor shall they permit any of their Subsidiaries to, directly or indirectly, lease all or substantially all of their properties or assets, in one or more related transactions, to any Person that is not a Reliant Retail Obligor.

          (d) For the avoidance of doubt, nothing in this Section 7.04 is intended to prohibit any Asset Sale permitted by Section 7.05.

          7.05. Asset Sales.

          (a) Consummate an Asset Sale unless (i) it receives consideration at the time of such Asset Sale that is not less than $0 and at least equal to the Fair Market Value of the assets issued or sold or otherwise disposed of (as reasonably determined by such Reliant Retail Obligor), (ii) at least 90% (or, in the case of an Asset Sale comprised of any tangible personal property, 75%) of the consideration therefor received in the Asset Sale by RERH Holdings or such Subsidiary is in the form of cash or Cash Equivalents (which, except for cash used to close out existing Power and Hedging Contracts related to the supply for the assets sold, shall be applied to the repayment of any outstanding principal and interest on the Working Capital Facility and payment of outstanding Reimbursement Obligations then due, with surplus being deemed and available for application in accordance with Section 6.11(c)) and (iii) it has closed out existing Power and Hedging Contracts necessary to close out substantially all of the supply for the assets sold (and caused the return of any ML Guarantee relating to such supply or such assets being sold). For purposes of this provision, each of the following shall be deemed to be cash:

liabilities that are by their terms subordinated to the Credit Sleeve Obligations) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases such Reliant Retail Obligor from further liability;

     (B) any securities, notes or other Obligations received by a Reliant Retail Obligor from such transferee that are converted (by sale or other disposition) by such Reliant Retail Obligor into cash, to the extent of the cash received in that conversion within 60 days; and

          (b) Consummate any sale, lease, conveyance or other disposition (i) comprised of Residential Mass Customers, (ii) comprised of any Mark, or any rights in any Information Technology Systems (except for termination or expiration of licenses or leases for Information Technology Systems in the ordinary course of business), the IT Trust (except in accordance with the IT Trust Transfer and Allocation Plan) or the NRG IT Trust, (iii) comprised of the Equity Interests in REPS or any other Subsidiary of RERH Holdings, (iv) comprised of all or substantially all of the assets of REPS or any other Subsidiary of RERH Holdings or (v) to the extent a Reliant Default or Reliant Event of Default would result therefrom.

REPS agrees to keep the Merrill Parties reasonably apprised of all negotiations and the material terms and conditions of any proposed sale, lease, conveyance or other disposition of any C&I Customers, and to the extent the Merrill Parties elect to provide any comments to REPS with respect to the terms and conditions or documentation of any such sale or other disposition (which comments are provided to REPS within a commercially reasonable time period), REPS agrees such comments will be accepted to the extent determined by the Reliant Retail Obligors using their reasonable business judgment.

          7.06. Limitation on Issuances and Sales of Equity Interests.

The Reimbursement Guarantors hereby jointly and severally agree, in furtherance of the foregoing and not in limitation of any other right which any Merrill Party may have at law or in equity against any Reimbursement Guarantor by virtue hereof, that upon the failure of REPS to pay any of the Guaranteed Obligations when and as the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C. Section 362(a)), the Reimbursement Guarantors will upon demand pay, or cause to be paid, in accordance with the terms of this Agreement, to the Merrill Parties, an amount equal to the sum of the unpaid principal amount of all Guaranteed Obligations then due as aforesaid, accrued and unpaid interest on such Guaranteed Obligations (including interest which, but for REPS’s becoming the subject of a case under the Bankruptcy Code, would have accrued on such Guaranteed Obligations, whether or not a claim is allowed against REPS for such interest in the related bankruptcy case) and all other Guaranteed Obligations then owed to the Merrill Parties as aforesaid.

          11.03. Liability of Reimbursement Guarantors Absolute. Each Reimbursement Guarantor agrees that its obligations hereunder are irrevocable, absolute, independent and unconditional and shall not be affected by any circumstance which constitutes a legal or equitable discharge of a guarantor or surety other than payment in full of the Guaranteed Obligations. In furtherance of the foregoing and without limiting the generality thereof, each Reimbursement Guarantor agrees as follows:

     (a) this Reimbursement Guaranty is a guaranty of payment when due and not of collectability. This Reimbursement Guaranty is a primary obligation of each Reimbursement Guarantor and not merely a contract of surety;

     (b) the obligations of each Reimbursement Guarantor hereunder are independent of the obligations of REPS and the obligations of any other guarantor (including any other Reimbursement Guarantor) of the obligations of REPS, and a separate action or actions may be brought and prosecuted against such Reimbursement Guarantor whether or not any action is brought against REPS or any of such other guarantors and whether or not REPS is joined in any such action or actions;

     (c) payment by any Reimbursement Guarantor of a portion, but not all, of the Guaranteed Obligations shall in no way limit, affect, modify or abridge any Reimbursement Guarantor’s liability for any portion of the Guaranteed Obligations which

has not been paid; and without limiting the generality of the foregoing, if the Merrill Parties is awarded a judgment in any suit brought to enforce any Reimbursement Guarantor’s covenant to pay a portion of the Guaranteed Obligations, such judgment shall not be deemed to release such Reimbursement Guarantor from its covenant to pay the portion of the Guaranteed Obligations that is not the subject of such suit, and such judgment shall not, except to the extent satisfied by such Reimbursement Guarantor, limit, affect, modify or abridge any other Reimbursement Guarantor’s liability hereunder in respect of the Guaranteed Obligations;

     (d) any Merrill Party, upon such terms as it deems appropriate, without notice or demand and without affecting the validity or enforceability hereof or giving rise to any reduction, limitation, impairment, discharge or termination of any Reimbursement Guarantor’s liability hereunder, from time to time may (i) renew, extend, accelerate, increase the rate of interest on, or otherwise change the time, place, manner or terms of payment of the Guaranteed Obligations; (ii) settle, compromise, release or discharge, or accept or refuse any offer of performance with respect to, or substitutions for, the Guaranteed Obligations or any agreement relating thereto and/or subordinate the payment of the same to the payment of any other obligations; (iii) request and accept other guaranties of the Guaranteed Obligations and take and hold security for the payment hereof or the Guaranteed Obligations; (iv) release, surrender, exchange, substitute, compromise, settle, rescind, waive, alter, subordinate or modify, with or without consideration, any security for payment of the Guaranteed Obligations, any other guaranties of the Guaranteed Obligations, or any other obligation of any Person (including any other Reimbursement Guarantor) with respect to the Guaranteed Obligations; (v) enforce and apply any security now or hereafter held by or for the benefit of such Merrill Party in respect hereof or the Guaranteed Obligations and direct the order or manner of sale thereof, or exercise any other right or remedy that such Merrill Party may have against any such security, in each case as such Merrill Party in its discretion may determine consistent herewith or any applicable security agreement, including foreclosure on any such security pursuant to one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable, and even though such action operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of any Reimbursement Guarantor against REPS or any security for the Guaranteed Obligations; and (vi) exercise any other rights available to it under the Transaction Documents; and

     (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 REPS 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 REPS, 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 REPS, any such other guarantor or any other Person, (iii) proceed against or have resort to any balance of any Collateral Account or credit on the books of any Merrill Party in favor of REPS 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 REPS 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 REPS 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. Reimbursement Guarantors’ Rights of Subrogation, Contribution, etc. Until the Guaranteed Obligations shall have been indefeasibly paid in full (other than indemnities and any similar obligations of the Reliant Retail Obligors not then due and payable and that expressly survive termination of this Agreement and the other Transaction Documents),

each Reimbursement Guarantor hereby agrees not to exercise any claim, right or remedy, direct or indirect, that such Reimbursement Guarantor now has or may hereafter have against REPS or any other Reimbursement Guarantor or any of its assets in connection with this Reimbursement Guaranty or the performance by such Reimbursement Guarantor of its obligations hereunder, in each case whether such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise and including (a) any right of subrogation, reimbursement or indemnification that such Reimbursement Guarantor now has or may hereafter have against REPS with respect to the Guaranteed Obligations, (b) any right to enforce, or to participate in, any claim, right or remedy that any Merrill Party now has or may hereafter have against REPS, and (c) any benefit of, and any right to participate in, any collateral or security now or hereafter held by any Merrill Party. In addition, until the Guaranteed Obligations shall have been indefeasibly paid in full (other than indemnities and any similar obligations of the Reliant Retail Obligors not then due and payable and that expressly survive termination of this Agreement and the other Transaction Documents), each Reimbursement Guarantor shall withhold exercise of any right of contribution such Reimbursement Guarantor may have against any other guarantor (including any other Reimbursement Guarantor) of the Guaranteed Obligations, including any such right of contribution as contemplated by Section 11.02. Each Reimbursement Guarantor further agrees that, to the extent the agreement to withhold the exercise of its rights of subrogation, reimbursement, indemnification and contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation, reimbursement or indemnification such Reimbursement Guarantor may have against REPS or against any collateral or security, and any rights of contribution such Reimbursement Guarantor may have against any such other guarantor, shall be junior and subordinate to any rights any Merrill Party may have against REPS, to all right, title and interest any Merrill Party may have in any such collateral or security, and to any right any Merrill Party may have against such other guarantor. If any amount shall be paid to any Reimbursement Guarantor on account of any such subrogation, reimbursement, indemnification or contribution rights at any time when all Guaranteed Obligations shall not have been finally and indefeasibly paid in full (other than indemnities and any similar obligations of the Reliant Retail Obligors not then due and payable and that expressly survive termination of this Agreement and the other Transaction Documents), such amount shall be held in trust for the Merrill Parties and shall forthwith be paid over to the Merrill Parties to be credited and applied against the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms hereof.

          11.06. Subordination of Other Obligations. Any Indebtedness of REPS or any Reimbursement Guarantor now or hereafter held by any Reimbursement Guarantor (the “Obligee Guarantor”) is hereby subordinated in right of payment to the Guaranteed Obligations during the existence of a Reliant Event of Default, and any such indebtedness collected or received by the Obligee Guarantor during the existence of a Reliant Event of Default shall be held in trust for the Merrill Parties and shall forthwith be paid over to the Merrill Parties to be credited and applied against the Guaranteed Obligations but without affecting, impairing or limiting in any manner the liability of the Obligee Guarantor under any other provision hereof.

          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 indefeasibly paid in full. Each Reimbursement Guarantor hereby

irrevocably waives any right to revoke this Reimbursement Guaranty as to future transactions giving rise to any Guaranteed Obligations.

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

          11.09. Financial Condition of REPS. Any Reimbursement Guarantee may be made to REPS or continued from time to time, without notice to or authorization from any Reimbursement Guarantor regardless of the financial or other condition of REPS 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 REPS. Each Reimbursement Guarantor has adequate means to obtain information from REPS on a continuing basis concerning the financial condition of REPS 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 REPS 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 REPS now known or hereafter known by any Merrill Party.

          11.10. Bankruptcy, etc.

          (a) So long as any Guaranteed Obligations remain outstanding, no Reimbursement Guarantor shall, without the prior written consent of Merrill Parties acting pursuant to the instructions of Requisite Lenders, commence or join with any other Person in commencing any bankruptcy, reorganization or insolvency case or proceeding of or against REPS or any other Reimbursement Guarantor or admit in writing or in any legal proceeding that it is unable to pay its debts as they become due. The obligations of Reimbursement Guarantors hereunder shall not be reduced, limited, impaired, discharged, deferred, suspended or terminated by any case or proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of REPS or any other Reimbursement Guarantor or by any defense which REPS or any other Reimbursement Guarantor may have by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding.

          (b) Each Reimbursement Guarantor acknowledges and agrees that any interest on any portion of the Guaranteed Obligations which accrues after the commencement of any case or proceeding referred to in clause (a) above (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 REPS 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.

          (c) In the event that all or any portion of the Guaranteed Obligations are paid by REPS, 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.

     (b) In addition to the confidentiality restrictions with respect to third parties in paragraph (a) above, the Merrill Parties agree that:

          12.05. Waiver. No failure on the part of any Party to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under this Agreement preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The remedies provided herein are cumulative and not exclusive of any remedies provided by law.

          12.06. Amendments, Etc.. Except as otherwise expressly provided in this Agreement, any provision of this Agreement or in any other Transaction Document between or among any of the Merrill Parties, on one hand, and any of the Reliant Retail Obligors, on the other hand, may be modified or supplemented only by an instrument in writing signed by the applicable Parties thereto.
