Explanation of Responses:
1. Includes Restricted Stock Units ("RSUs") issued to Mr. Stark by NRG Energy, Inc. under NRG's Long Term Incentive Plan ("LTIP"). Each RSU is equivalent in value to one share of NRG's Common Stock, par value $.01. Mr. Stark will receive from NRG one such share of Common Stock, as follows: (i) 1,300 RSUs issued on January 4, 2013; (ii) 1,600 RSUs issued on January 3, 2014; (iii) 2,600 RSUs issued on January 3, 2015.
2. Pursuant to the Grant Agreement by and between NRG Energy, Inc. and Mr. Stark, all of the Stock Options vested and became exercisable on January 2, 2012.
3. Pursuant to the Grant Agreement by and between NRG Energy, Inc. and Mr. Stark, 66 2/3% of the Stock Options vested and became exercisable on January 4, 2012. The remaining balance will vest on January 4, 2013.
4. Pursuant to the Grant Agreement by and between NRG Energy, Inc. and Mr. Stark, 33 1/3% of the Stock Options vested and became exercisable on January 3, 2012. The remaining balance will vest as follows: 33 1/3% on January 3, 2013 and January 3, 2014.
5. Mr. Stark was issued 1,300 Performance Units ("PUs") under NRG Energy, Inc.'s LTIP on January 4, 2010.
6. Each PU will be paid out on January 4, 2013 if the average of the closing price of NRG's Common Stock on January 4, 2013 and the nineteen preceding tracking days (the "Measurement Price") is equal to or greater than $31.97 (the "Threshold Price"). The payout for each PU will be equal to a pro-rated amount in between one-half and one share of Common Stock if the Measurement Price equals or exceeds the Threshold Price but is less than $34.69 (the "Target Price"). The payout for each PU will be equal to one share of Common Stock if the Measurement Price equals the Target Price. The payout for each PU will be equal to a pro-rated amount in between one and two shares of Common Stock if the Measurement Price is greater than the Target Price but less than $40.57 (the "Maximum Price"). The payout for each PU will be equal to two shares of Common Stock if the Measurement Price is equal to or greater than the Maximum Price.
7. Mr. Stark was issued 1,500 PUs under NRG Energy, Inc.'s LTIP on January 3, 2011.
8. Each PU will be paid out on January 3, 2014 if the average of the closing price of NRG's Common Stock on January 3, 2014 and the nineteen preceding tracking days (the "Measurement Price") is equal to or greater than $24.57 (the "Threshold Price"). The payout for each PU will be equal to a pro-rated amount in between one-half and one share of Common Stock if the Measurement Price equals or exceeds the Threshold Price but is less than $26.66 (the "Target Price"). The payout for each PU will be equal to one share of Common Stock if the Measurement Price is equal to the Target Price.

The payout for each PU will be equal to two shares of Common Stock if the Measurement Price is equal to or greater than the Maximum Price.
9. Mr. Stark was issued 4,300 Market Stock Units ("MSUs") by NRG under the LTIP on January 3, 2012. The MSUs will convert to shares of NRG Common Stock on January 3, 2015 only in the event the Company has achieved a certain level of total shareholder return ("TSR"). TSR will consist of the average of the closing price of NRG's Common Stock on January 3, 2015 and the nineteen preceding trading days and any dividends paid since the grant date as determined by the Compensation Committee.
10. Mr. Stark will receive a maximum of 8,600 shares of Common Stock if the Company has achieved a 100% increase in TSR since the grant date (the "Maximum"); 4,300 shares of Common Stock if there is no change in TSR since the grant date (the "Target"); or 2,150 shares of Common Stock if there is a 50% decrease in TSR since the grant date (the "Threshold"). Mr. Stark will not receive any shares of Common Stock if TSR has decreased by more than 50% since the grant date. The number of shares of Common Stock that Mr. Stark may receive is interpolated for TSR falling between Threshold, Target, and Maximum levels.
