PRINCETON, N.J.--(BUSINESS WIRE)--Dec. 29, 2005--NRG Energy, Inc. (NYSE:NRG) today announced that as of 5:00 p.m., New York City time, on December 29, 2005, it had received valid tenders and consents from holders of approximately $1,124,875,000 in aggregate principal amount of Texas Genco LLC's and Texas Genco Financing Corp.'s 6.875% senior notes due 2014 (CUSIP Nos. 882444AA0, U88243AA5) (the "Texas Genco Notes"), representing approximately 99.98% of the outstanding Texas Genco Notes, in connection with its previously announced tender offer and consent solicitation for the Texas Genco Notes pursuant to NRG's Offer to Purchase and Consent Solicitation Statement dated December 15, 2005 relating to the Texas Genco Notes.

With the receipt of the requisite consents, Texas Genco will execute a supplemental indenture governing the Texas Genco Notes which will amend the indenture under which the Texas Genco Notes were issued to eliminate substantially all of the restrictive covenants and events of default and related provisions in the indenture, which satisfies the "Supplemental Indenture Condition," as defined in NRG's Offer to Purchase and Consent Solicitation Statement dated December 15, 2005 relating to the Texas Genco Notes. The amendments to the indenture will not become operative until payment for all validly tendered Texas Genco Notes is made by NRG.

Consummation of the tender offer is conditioned upon the satisfaction of certain conditions, including (1) NRG having obtained funds sufficient to pay the consideration, costs and expenses of the tender offer and consent solicitation from the financing transactions related to the pending acquisition of Texas Genco LLC, (2) the consummation of NRG's pending acquisition of Texas Genco LLC, and (3) certain other customary conditions. There can be no assurance that any of such conditions will be met.

Texas Genco Notes may be tendered pursuant to the tender offer until 5:00 p.m., New York City time, on January 31, 2006 (the "Expiration Date"), or such later date and time to which the Expiration Date is extended, unless the tender offer is earlier terminated by NRG. Holders who validly tender Texas Genco Notes after 5:00 p.m., New York City time, on December 29, 2005, but on or prior to the Expiration Date will not be eligible to receive the consent payment of $30.00 per $1,000 principal amount of the Texas Genco Notes. Any Texas Genco Notes not tendered and purchased pursuant to the tender offer will remain outstanding and the holders thereof will be bound by the amendments contained in the supplemental indenture eliminating substantially all of the restrictive covenants in the indenture even though they have not consented to the amendments.

Subject to the terms and conditions of the tender offer and consent solicitation, payment for tendered Texas Genco Notes will be made on the first business day following the Expiration Date, or as soon thereafter as practicable.

The complete terms and conditions of the tender offer and consent solicitation are described in the Offer to Purchase and Consent Solicitation Statement dated December 15, 2005 relating to the Texas Genco Notes, copies of which may be obtained from MacKenzie Partners, Inc., the information agent for the tender offer and consent solicitation, at 800.322.2885 (U.S. Toll Free) and 212.929.5500 (collect).
