Parent hereby acknowledges that the Initial Contribution to RERH Holdings hereunder is absolute and irrevocable, without reservation or retention of any interest whatsoever by Parent. RERH hereby irrevocably directs Parent to make the Initial Contribution directly as if it were “revenue” under Section 6.11 of the CSRA.

SECTION 2.2 Contingent Equity Contributions.

          (a) If, and only if, on November 1, 2009, the then outstanding Exposure under the CSRA exceeds the Target Exposure for such date (the “Additional Contribution Trigger”), Parent shall within two (2) Business Days of such date, make a capital contribution in cash to RERH equal to $250,000,000 (“Additional Contribution”). Parent hereby acknowledges that any Additional Contribution to RERH hereunder, subject to the occurrence of the Additional Contribution Trigger or an Accelerated Contribution Event, (i) is absolute and irrevocable, without recourse, without reservation or retention of any interest whatsoever by Parent and (ii) shall be required to be contributed by Parent regardless of whether the amount of such Additional Contribution would be sufficient to reduce Exposure under the CSRA to the amount required for such date in the ESDS. RERH hereby irrevocably directs Parent to make all Additional Contributions directly to the account of MLCI in accordance with Section 6.18 of the CSRA.

          (b) If, and only if, on October 31, 2010, either (i) the Exposure under the CSRA is in excess of zero or (ii) the Credit Sleeve Termination Date has not occurred (either of (i) or (ii), a “Final Contribution Trigger”), Parent shall on such date make a capital contribution in cash to RERH in an amount sufficient to permit RERH to reduce Exposure under the CSRA to zero on such date and to the extent necessary to cause the Credit Sleeve Termination Date to occur on such date (“Final Contribution” and together with any Additional Contribution, the “Contingent Equity Contributions”); provided, that Parent shall not be obligated to contribute an amount under this clause (b) in excess of $400 million (“Maximum Amount of the Final Contribution”).

Each of NRG Retail and RERH Holdings hereby acknowledges that it shall not have any interest in or right to any Contingent Equity Contribution and to the extent it shall be deemed to have any such interest or right therein it hereby absolutely and irrevocably assigns all of its rights, title and interest hereunder (including to any Contingent Equity Contributions hereunder), without recourse, without reservation or retention of any interest whatsoever to RERH.

          (e) The Parent, NRG Retail, RERH Holdings and RERH agree that the obligations of the Parent are not conditioned on RERH, NRG Retail or RERH Holdings issuing any securities to the Parent, NRG Retail or RERH Holdings in respect of any payment made in respect of the Parent’s obligations pursuant to Sections 2.1 and 2.2 hereof and the obligations of the Parent shall not be construed as an obligation of the Parent, NRG Retail or RERH Holdings to extend a loan, credit or financial accommodation to NRG Retail, RERH Holdings or RERH.

     (f) any representation, warranty, certification or statement of fact made or deemed made by the Parent herein, in any Transaction Document or in any document delivered in connection herewith or therewith shall be incorrect or misleading in any material respect when made or deemed made; or

SECTION 2.4 Waiver.

          (a) RERH or MLCI may at any time, without the consent of the Parent, without notice to the Parent and without affecting or impairing RERH’s or the MLCI’s rights, or impairing the Parent’s obligations hereunder, do any of the following with respect to any Obligation under the Transaction Documents: (a) in accordance with the terms of the Transaction Documents, make changes,

amendments, modifications or waivers thereof) for the benefit of MLCI; provided that if the NRG Credit Agreement is no longer in effect or at any time the aggregate outstanding principal amount of Indebtedness outstanding and/or available to be drawn thereunder is less than $100 million then the foregoing clause shall be deemed to apply to such Specified Covenants as the same were in effect immediately before the NRG Credit Agreement ceased to be in effect or immediately before the aggregate outstanding principal amount and/or amount available to be drawn thereunder was reduced to less than $100 million, as the case may be, and without giving effect to any amendments or waivers entered into immediately prior to or otherwise in connection with the termination of such agreement or such reduction in principal amount and provided further that (i) with respect to Section 5.02 of the NRG Credit Agreement the following clause shall not apply “maintain such other insurance as otherwise required by the Security Documents”, (ii) with respect to Section 6.07 of the NRG Credit Agreement, to the extent that the incorporation of such Section herein would result in a breach under such Section under the NRG Credit Agreement or under Section 4.08 of the Senior Note Documents, such incorporation shall be deemed null and void only to the extent necessary to prevent such breach from occurring and (iii) nothing in this Agreement shall limit the Liens of the lenders or the loans under the NRG Credit Agreement with respect to the Parent or any of its Subsidiaries other than RERH Holdings and its Subsidiaries.

     Notwithstanding anything to the contrary in this Agreement or any other Transaction Document, (x) Parent shall have at all times the right (and MLCI shall have no right or claim in respect of any such action) to amend, restate, supplement, replace, obtain waivers or consents, or otherwise modify any and all terms and conditions of the NRG Credit Agreement (including the Specified Covenants) in accordance with the terms thereof (provided that after the date when the aggregate outstanding principal amount of Indebtedness outstanding and/or available to be drawn thereunder was reduced to less than $100 million, no such amendment, restatement, supplement, replacement, waiver or modification shall affect the Specified Covenants hereunder), and (y) (except following the date when the aggregate outstanding principal amount of Indebtedness outstanding and/or available to be drawn under the NRG Credit Agreement was reduced to less than $100 million) a waiver of any breach of, or consent obtained under, any term or condition of the NRG Credit Agreement (including with respect to the Specified Covenants) obtained in accordance with the terms and conditions thereof shall operate, automatically and without further action, as a waiver or consent in respect of the same terms and conditions under this Agreement and any other Transaction Document as relevant to the Specified Covenants.
