Explanation of Responses:

1. On December 18, 2006, Mr. Ragan was issued 6,300 Restricted Stock Units ("RSU's") by NRG Energy, Inc. under NRG Energy, Inc.'s Long Term Incentive Plan (the "LTIP"). Each RSU is equivalent in value to one share of NRG's Common Stock, par value $0.01. On December 18, 2009, 6,300 of the originally granted 6,300 RSUs vested. Pursuant to the LTIP, Mr. Ragan elected to satisfy his tax withholding obligation upon the exchange of common stock for RSU's by surrendering a number of shares of common stock having a value on the date of the exchange equal to the tax withholding obligation. This form is being filed to reflect the surrender of 2,108 shares of common stock to satisfy the grantee's tax withholding obligation.
