(“NRG”), NRG Energy Holdings Inc., EME, certain of EME’s debtor subsidiaries, the Official Committee of Unsecured Creditors of EME and its debtor subsidiaries, the PoJo Parties (as defined therein) and the proponent noteholders thereto (the “PSA”) and (2) an Asset Purchase Agreement, dated October 18, 2013, by and among NRG, EME and NRG Energy Holdings Inc. (the “Acquisition Agreement,” together with the PSA, the “Agreements”). The sole purpose of this Amendment is to file the PSA and the Acquisition Agreement and applicable exhibits thereto as exhibits to the Original Report. Except for the foregoing, this Amendment does not amend, modify or update the disclosures contained in the Original Report. No changes were made to the text of the Original Report.

Important Information Regarding the Agreements

The Agreements and the description of the Agreements and the exhibits included therein contained in the Original Report have been provided in order to give investors and security holders information regarding the terms of the Agreements. They are not intended to provide any factual information about EME, NRG or their respective subsidiaries or affiliates. The representations, warranties and covenants contained in the Agreements (1) were made only for purposes of the Agreements and as of specific dates, (2) were solely for the benefit of the parties to the Agreements and the other persons and entities named as third-party beneficiaries of certain covenants therein and (3) may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made by each contracting party to the other for purposes of allocating contractual risk between them that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any description thereof as characterization of the actual state of facts or conditions of EME, NRG or any of their respective subsidiaries, affiliates or businesses. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Agreements, which subsequent information may or may not be fully reflected in the public disclosures by EME or NRG.
