WHEREAS, the Preferred Interests will be redeemable and exchangeable into cash and shares of common stock, par value $0.01, of NRG Energy, Inc. (the “Company”, and such common stock, the “NRG Common Stock”) in accordance with the Certificate
of Designations; and

WHEREAS, the Preferred Interests will be offered and sold to Purchaser without registration under the Securities Act of 1933, as amended (the “Act”), in reliance on an exemption pursuant to Section 4(2) under the Act;

NOW, THEREFORE, in consideration of their mutual covenants herein contained, the parties hereto, intending to be legally bound, hereby mutually covenant and agree as follows:

“Note Purchase Agreement” means the Note Purchase Agreement dated as of August 4, 2006 among Issuer, Credit Suisse International and Credit Suisse Securities (USA) LLC, as agent.

“Potential Early Redemption Event” means any event that, with the passage of time or giving of notice or both, will constitute an Early Redemption Event.

2. Single Agreement. All Preferred Interests are issued and sold by Issuer and purchased by Purchaser pursuant to this Agreement in reliance on the fact that this Agreement, the Pricing Confirmation and all Preferred Interests issued hereunder form a single agreement between the parties, and the parties would not otherwise issue and sell or purchase any Preferred Interests.

3. Sale and Purchase. (a) Upon the terms and subject to the conditions set forth herein, Issuer agrees to issue and sell to Purchaser, and Purchaser agrees to purchase from Issuer, Preferred Interests having the terms set forth in the Certificate of Designations and in the Pricing Confirmation.

(c) Purchaser will make payment to Issuer in immediately available funds by wire transfer to an account designated by Issuer on each day that is one Settlement Cycle following each Exchange Business Day in the Reference Period (each such date of payment, a “Funding Date”) in an amount equal to the Daily Funding Amount for such Funding Date.

(d) On the last Exchange Business Day of the Reference Period, the Calculation Agent will deliver to the parties a pricing confirmation setting forth the final pricing terms of the Preferred Interests issued on the Issue Date (a “Pricing Confirmation”), duly completed and substantially in the form of Exhibit B hereto. Upon receipt of the Pricing Confirmation, the parties will each execute a copy thereof; provided that regardless of whether either party executes a copy of the Pricing Confirmation, the terms set forth in the Pricing Confirmation shall be binding on the parties absent manifest error, unless such party notifies the other party that it reasonably believes that an error has been made in the computation of such terms within three Business Days of receipt thereof, in which case the parties shall work together to determine the correct terms.
