Pursuant to Section 18-215 of the
Limited Liability Company Act of the State of Delaware

          NRG COMMON STOCK FINANCE I LLC, a limited liability company organized and existing under the Limited Liability Company Act of the State of Delaware (“Issuer”), does hereby certify that (i) pursuant to authority conferred upon the directors of Issuer (the “Directors”) by its Limited Liability Company Agreement and pursuant to the provisions of Section 18-215 of the Limited Liability Company Act of the State of Delaware, the Directors authorized the creation and issuance of Issuer’s Series 1 Exchangeable Limited Liability Company Preferred Interests (the “Preferred Interests”), and (ii) the following resolution fixing the designations, preferences and rights of such Preferred Interests, which was duly adopted by the Directors, on August 4, 2006, remains in full force and effect. Certain capitalized terms used herein are defined in Article 10.

          NOW THEREFORE IT IS RESOLVED, that pursuant to Section 18-215 of the Limited Liability Company Act of Delaware and the authority expressly granted to and vested in the Directors by the provisions of the Limited Liability Company Agreement of NRG Common Stock Finance I LLC, the Directors hereby create a series of preferred limited liability company interests with the designations, preferences and relative, participating, optional or other special rights, and the qualifications, limitations and restrictions as set forth in this Certificate of Designations:

1.     Designation; Components

          1.1     The series will be known as the Series 1 Exchangeable Limited Liability Company Preferred Interests.

          1.2     Each Preferred Interest issued hereunder shall consist of 30 separate components (each, a “Component”). The payments and deliveries by Issuer in respect of any Preferred Interest shall be made as if each Component were a separate Preferred Interest.

2.     Dividends

          2.1     The Preferred Interests will not pay dividends and the Holders will not be entitled to receive dividends.

3.     Ranking

          3.1     The Preferred Interests will, with respect to distributions upon the liquidation, winding up or dissolution of Issuer, rank:

               (a)     senior to all classes of common equity interests in Issuer, including without limitation the common equity limited liability company interests in Issuer (collectively, the “Junior Interests”); and

               (b)     junior to Issuer’s debt obligations, including without limitation the Notes issued by Issuer pursuant to the Note Purchase Agreement (collectively referred to as the “Senior Obligations”).

4.     Redemption and Exchange

          4.1     Redemption

          On the Redemption Date for each Component of each Preferred Interest, such Component shall be redeemed and Issuer shall make a payment to the Holder of such Preferred Interest in Cash equal to the Base Liquidation Preference for such Component as of such
Redemption Date.

          4.2     Exchange

          In addition to payment of the Base Liquidation Preference as provided in Section 4.1, each Holder shall have the right to exchange each Component of each Preferred Interest held by such Holder for the Preferred Net Settlement Amount for such Component by giving notice to Issuer on or prior to the fifth Scheduled Trading Day immediately prior to the Initial Valuation Date. On the Redemption Date for each Component of each Preferred Interest so exchanged, Issuer shall (in addition to paying the Base Liquidation Preference as set forth in Section 4.1) make a payment and/or a delivery to such Holder of (i) an amount in cash equal to the product of the Preferred Net Settlement Amount for such Component and the Cash Settlement Percentage and (ii) a number of shares of NRG Common Stock equal to (x) the product of (A) such Preferred Net Settlement Amount and (B) one minus the Cash Settlement Percentage divided by (y) the VWAP Price on the Valuation Date for such Component; provided that such number of shares so delivered in respect of any Component of any Preferred Interest shall not exceed 86.7661% of the Number of Underlying Shares for such Component.

          Issuer may, by written notice to all Holders on or prior to the third Scheduled Trading Day immediately prior to the Initial Valuation Date, specify a cash settlement percentage (a “Cash Settlement Percentage”) for all Preferred Interests. For the avoidance of doubt, if Issuer does not so specify a Cash Settlement Percentage, the Cash Settlement Percentage shall be zero.

          Payment of Cash and/or delivery of shares of NRG Common Stock in accordance with the provisions of Section 4.1 and Section 4.2 shall be deemed to satisfy Issuer’s obligation to pay the Liquidation Preference for the relevant Preferred Interests.

          4.3     Optional Redemption

          Issuer may, by not less than 10 nor more than 30 Business Days’ prior written notice to all Holders, and subject to the execution by Issuer of such documentation as may be reasonably required based on advice of counsel to such Holders, designate an early redemption date (an “Optional Early Redemption Date”) for any or all of the Components comprising all or part of any Preferred Interest outstanding at the time (each, a “Relevant Component”).

If Issuer elects to redeem any Relevant Component in part, it shall also designate a percentage (the “Redemption Percentage”) representing the portion of such Relevant Component to be redeemed, and such Relevant Component shall be deemed to be two Preferred Interests with terms identical to those of the Relevant Component, except that the first such Component (the “Redeemed Component”) shall have an Initial Base Liquidation Preference equal to the product of the Redemption Percentage and the Initial Base Liquidation Preference for such Relevant Component, and the second such Component (the “Surviving Component”) shall have an Initial Base Liquidation Preference equal to the product of (x) one minus the Redemption Percentage and (y) the Initial Base Liquidation Preference for such Relevant Component. Issuer shall pay the Termination Amount for all Relevant Components (or, in the case of a partial redemption, all Redeemed Components) on the Optional Early Redemption Date. In the case of a partial redemption, each Surviving Component shall survive and continue to be outstanding with the rights and preferences set forth herein.

          Except as expressly set forth herein, upon payment of the Termination Amount for any Component for which an Optional Early Redemption Date has so been declared, all of Issuer’s obligations in respect of the payment and/or delivery pursuant to Section 4.1 and Section 4.2 shall be deemed satisfied with respect to such Component.

          4.4     Adjustment Events

          (a)     If the Calculation Agent has reasonably determined that an Adjustment Event either has occurred or is reasonably likely to occur, then the Calculation Agent will determine whether such Adjustment Event has or is reasonably likely to have a diluting or concentrative effect on the theoretical value of the shares of NRG Common Stock or options on NRG Common Stock and, if so, will make the corresponding adjustment to the Threshold Price (and, in the case of an Adjustment Event of the type described in clause (i) or clause (ii)(A) or (B) of Section 4.4(b), to the Notional Number of Shares) to compensate the Holders on account of such an Adjustment Event.

          (b)     “Adjustment Event” means any of the following:

          (i)     a subdivision, consolidation or reclassification of the NRG Common Stock, or a free distribution or dividend of any shares of NRG Common Stock to existing holders by way of bonus, capitalization or similar issue;

          (ii)     a distribution, issue or dividend to existing holders of NRG Common Stock of (A) such shares, or (B) other share capital or securities granting the right to payment of dividends and/or the proceeds of liquidation of the Company equally or proportionately with such payments to holders of such shares, or (C) share capital or other securities of another issuer acquired or owned (directly or indirectly) by the Company as a result of a spin-off or other similar transaction, or (D) any other type of securities, rights or warrants or other assets, in any case for payment (cash or other consideration) at less than the prevailing market price as reasonably determined by the
Calculation Agent;

          (iii)     any cash dividend or distribution on NRG Common Stock;

          (iv)     a repurchase by the Company or any of its subsidiaries of NRG Common Stock (other than the repurchase of the Notional Number of Shares) whether out of profits or capital and whether the consideration for such repurchase is cash, securities or otherwise;

          (v)     in respect of the Company, an event that results in any shareholder rights being distributed or becoming separated from shares of common stock or other shares of the capital stock of the Company pursuant to a shareholder rights plan or arrangement directed against hostile takeovers that provides upon the occurrence of certain events for a distribution of preferred stock, warrants, debt instruments or stock rights at a price below their market value, as reasonably determined by the Calculation Agent, provided that any adjustment effected as a result of such an event shall be readjusted upon any redemption of such rights; or

          (vi)     any other event that may have a diluting or concentrative effect on the theoretical value of the NRG Common Stock or options on NRG Common Stock, as reasonably determined by the Calculation Agent.

          4.5     Increased Cost Of Hedging and Increased Costs.

          The Calculation Agent may reduce the Threshold Price for any Preferred Interests to account for any period in which it reasonably determines that an Increased Cost of Hedging or an Increased Cost exists in respect of such Preferred Interests.

          4.6     Blackout Adjustments.

          If a Blackout or Suspension Day occurs pursuant to the Underwriting Agreement during the Double Print Period, then the Calculation Agent will make such adjustments to any of the Notional Number of Shares, the Threshold Price, any Preferred Net Settlement Amount or any other term of the Preferred Interests as it reasonably determines are appropriate to preserve the economic value of the transactions contemplated hereby to the Holders due to potential risks under applicable securities laws relating to such Holder’s ability to adjust their hedges in respect of the transactions contemplated by the Transaction Documents as a result of such a Blackout, and, if the Calculation Agent reasonably determines that such adjustments would be insufficient to preserve such economic value to the Holders, then the Holders shall have a right to accelerate such a portion of the Preferred Interests that would preserve such economic value to such Holders (and such an acceleration shall be treated as the designation of an Extraordinary Redemption Date).

          4.7     Use of Cash.

          Issuer shall not make any payment in respect of any Preferred Interest on or after the Initial Valuation Date using Cash not held in the Note Collateral Account as of 8:00AM, New York City time, on the Initial Valuation Date.

5.     Early Redemption Events

          5.1     The occurrence of any of the following events shall constitute an Early Redemption Event (an “Early Redemption
