CERTIFICATE OF DESIGNATIONS

establishing the

Voting Powers, Designations, Preferences, Limitations,

2.822% Convertible Perpetual Preferred Stock

Pursuant to Section 151 of the

General Corporation Law of the State of Delaware

A-5

NRG ENERGY, INC., a corporation organized and existing under the General Corporation Law of the State of Delaware (the “Issuer”), does hereby certify that (i) pursuant to authority conferred upon the Board of Directors of the Issuer by its Amended and Restated Certificate of Incorporation and pursuant to the provisions of Section 151 of the General Corporation Law of the State of Delaware, the Board of Directors authorized the creation and issuance of the Issuer’s 2.822% Convertible Perpetual Preferred Stock (the “Preferred Stock”), and (ii) the following resolution fixing the designations, preferences and rights of such Preferred Stock, which was duly adopted by the Board of Directors, on August 5, 2005, 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 151 of the General Corporation Law of Delaware and the authority expressly granted to and vested in the Board of Directors of the Issuer by the provisions of the Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) of the Issuer, the Board of Directors hereby creates a series of Preferred Stock, par value $0.01 per share, to consist initially of 250,000 shares, 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 and Number of Shares

1.1 The series will be known as the 2.822% Convertible Perpetual Preferred Stock.

1.2 The Preferred Stock will be a series consisting of 250,000 shares with a Liquidation Preference of $1,378.01 per share of the authorized but unissued preferred stock of the Issuer.

2. Dividends

2.1 Payment of Dividends

(a) Holders of Preferred Stock will be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for the payment of dividends, cash dividends at the annual rate of 3.625% of $1,000 per share from, and including, August 11, 2005 to, but excluding, December 30, 2014, and on and after December 30, 2014, at the annual rate of 2.822% of the Liquidation Preference per share. Such dividends shall be payable to Holders of Preferred Stock in arrears in equal amounts quarterly on each Dividend Payment Date, beginning December 15, 2005, in preference to, and in priority over, dividends on any Junior Stock but subject to the rights of any Holders of Senior Stock or Parity Stock.

(b) Dividends shall be cumulative from the initial date of issuance or the last Dividend Payment Date for which accumulated dividends were paid, whichever is later, whether or not funds of the Issuer are legally available for the payment of such dividends. Each such dividend shall be payable to the Holders of record of shares of the

A-6

Preferred Stock on each Dividend Payment Date, as they appear on the Issuer’s stock register at the close of business on such Dividend Payment Date. Accumulated and unpaid dividends for any past Dividend Periods may be declared and paid at any time, without reference to any Dividend Payment Date.

(c) Accumulated and unpaid dividends for any past Dividend Period (whether or not earned and declared) shall cumulate dividends at the annual rate of 8.0% and shall be payable in the manner set forth in this Section 2.1.

(d) The amount of dividends payable for each full Dividend Period for the Preferred Stock shall be computed by dividing the annual dividend rate by four. The amount of dividends payable for the initial Dividend Period, or any other period shorter or longer than a full Dividend Period, on the Preferred Stock shall be computed on the basis of twelve 30-day months and a 360-day year. Dividends on the shares of Preferred Stock will be payable in cash. Holders of Preferred Stock shall not be entitled to any dividends in excess of cumulative dividends (which, for the avoidance of doubt, shall include dividends paid or accumulated at an increased rate pursuant to Section 8.2), as herein provided, on the Preferred Stock.

(e) No dividend shall be declared or paid or set apart for payment or other distribution declared or made, whether in cash, obligations or shares of Capital Stock of the Issuer or other property, directly or indirectly, upon any shares of Junior Stock or Parity Stock, nor shall any shares of Junior Stock or Parity Stock be redeemed, repurchased or otherwise acquired for consideration by the Issuer through a sinking fund or otherwise, unless all accumulated and unpaid dividends through the most recent Dividend Payment Date (whether or not there are funds of the Issuer legally available for the payment of dividends) on the shares of Preferred Stock and any Parity Stock have been or contemporaneously are declared and paid in full or set apart for payment; provided, however, that, notwithstanding any provisions of this paragraph (e) to the contrary, the Issuer may redeem, repurchase or otherwise acquire for consideration Parity Stock pursuant to a purchase or exchange offer made on the same terms to all Holders of the Preferred Stock and Parity Stock. When dividends are not paid in full, as aforesaid, upon the shares of Preferred Stock, all dividends declared on the Preferred Stock and any other Parity Stock shall be declared and paid either (i) pro rata so that the amount of dividends so declared on the shares of Preferred Stock and each such other class or series of Parity Stock shall in all cases bear to each other the same ratio as accumulated dividends on the shares of Preferred Stock and such class or series of Parity Stock bear to each other or (ii) on another basis that is at least as favorable as clause (i) to the Holders of the Preferred Stock entitled to receive such dividends.

3. Ranking

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

(a) senior to all classes of Common Stock and each other class of Capital Stock or series of preferred stock issued by the Issuer, the terms of which

A-7

expressly provide that such class or series will rank junior to the Preferred Stock as to dividend distributions and distributions upon the liquidation, winding up or dissolution of the Issuer (collectively, with the Common Stock, referred to as the “Junior Stock”);

(b) on a parity with any class of Capital Stock or series of preferred stock issued by the Issuer, the terms of which expressly provide that such class or series will rank on a parity with the Preferred Stock as to dividend distributions and distributions upon the liquidation, winding up or dissolution of the Issuer, and the Issuer’s outstanding Existing Preferred Stock (collectively referred to as “Parity Stock”);

(c) junior to each class of Capital Stock (including warrants, rights, calls or options exercisable or convertible into warrants, rights or calls) or series of preferred stock issued by the Issuer, the terms of which expressly provide that such class or series will rank senior to the Preferred Stock as to dividend distributions and distributions upon liquidation, winding up or dissolution of the Issuer (collectively referred to as “Senior Stock”); and

(d) junior to all the Issuer’s existing and future debt obligations and all of its Subsidiaries’ (i) existing and future liabilities and (ii) Capital Stock held by Persons other than the Issuer or its Subsidiaries.

3.2 Except as otherwise provided herein, the Issuer is entitled to amend the Certificate of Incorporation to authorize one or more additional series of preferred stock, file certificates of designation, and issue without restriction from time to time, any series of Junior Stock, Parity Stock or Senior Stock.

4. Conversion

4.1 Conversion Rights

Each Holder of Preferred Stock shall have the right, at its option, at any time during the 90-day period beginning on December 23, 2019, to convert, subject to the terms and provisions of this Article 4, any or all of such Holder’s shares of Preferred Stock into cash and shares of Common Stock. A holder may convert fewer than all of its shares of Preferred Stock.

Any Holder of Preferred Stock intending to convert its shares of Preferred Stock shall give the Issuer written notice of such intention at least 40 Scheduled Trading Days prior to the intended date of such conversion. The Issuer shall, within five Scheduled Trading Days of the receipt of such notice, confirm in writing to such Holder its determination whether or not to make a cash payment in lieu of delivering the Net Shares in connection with such conversion and whether or not to receive cash in lieu of shares of Common Stock, if any, from such Holder pursuant to Section 8.1 in connection with such conversion, which determination shall be irrevocable and binding on the Issuer.

The Issuer shall have the right, at its option, at any time during the 90-day period beginning on December 23, 2019, to purchase any or all of any Holder’s shares of Preferred Stock; provided that the Issuer gives such Holder written notice of its decision

A-8

to exercise such right at least 40 Scheduled Trading Days prior to the intended date of such purchase; and provided, further, that upon receipt of such written notice, such Holder shall be deemed to have elected to convert on the date specified in such written notice the shares of Preferred Stock with respect to which the Issuer is exercising such right, and such shares of Preferred Stock shall be converted in accordance with the terms and provisions of Section 4.2; and provided, further, that the Issuer confirms in such notice its determination whether or not to make a cash payment in lieu of delivering the Net Shares in connection with such conversion and whether or not to receive cash in lieu of shares of Common Stock, if any, from such Holder pursuant to Section 8.1 in connection with such conversion, which determination shall be irrevocable and binding on the Issuer.

The Issuer acknowledges its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange Act and the rules and regulations thereunder, in respect of any election to make a cash payment to a Holder in lieu of delivering Net Shares or to receive cash in lieu of shares of Common Stock, if any, from a Holder pursuant to Section 8.1.

4.2 Conversion Procedures

Conversion of shares of the Preferred Stock may be effected by any Holder thereof upon the surrender to the Issuer, at the principal office of the Issuer or at the office of the Transfer Agent as may be designated by the Board of Directors, of the certificate or certificates for such shares of Preferred Stock to be converted accompanied by a complete and manually signed Conversion Notice (as set forth in the form of Preferred Stock certificate attached hereto) along with appropriate endorsements and transfer documents as required by the Transfer Agent. In case such Conversion Notice shall specify a name or names other than that of such Holder, such notice shall be accompanied by payment of all transfer taxes payable upon the issuance of shares of Common Stock in such name or names.

Other than such taxes, the Issuer shall pay any documentary, stamp or similar issue or transfer taxes that may be payable in respect of any issuance or delivery of shares of Common Stock upon conversion of shares of the Preferred Stock pursuant hereto. The conversion of the Preferred Stock will be deemed to have been made on the date (the “Conversion Date”) such certificate or certificates have been surrendered and the receipt of such Conversion Notice and payment of all required transfer taxes, if any (or the demonstration to the satisfaction of the Issuer that such taxes have been paid). Promptly (but no later than three Exchange Business Days) following the Conversion Date, the Issuer shall, in the case of cash, pay or cause to be paid in immediately available funds, an amount equal to, or, in the case of shares of Common Stock, deliver or cause to be delivered, (i) the Cash Conversion Amount, accumulated and unpaid dividends pursuant to Section 4.3 and certificates representing a number of validly issued, fully paid and nonassessable full shares of Common Stock equal to the Net Share Amount (or cash in lieu of such shares as provided in Section 4.4), and (ii) if less than the full number of shares of the Preferred Stock evidenced by the surrendered certificate or certificates is being converted, a new certificate or certificates, of like tenor, for the number of shares

A-9

evidenced by such surrendered certificate or certificates less the number of shares being converted. On the Conversion Date, the rights of the Holder of the Preferred Stock shall cease except for the right to receive cash and shares of Common Stock and the Person entitled to receive the shares of Common Stock shall be treated for all purposes as having become the Holder of such shares of Common Stock at such time.

4.3 Dividend and Other Payments Upon Conversion

If a Holder of shares of Preferred Stock exercises conversion rights, such shares will cease to accumulate dividends as of the end of the day immediately preceding the Conversion Date. Upon conversion of the Preferred Stock, the Holder shall be entitled to all accumulated and unpaid dividends in respect of those shares of Preferred Stock to the Conversion Date (including, for the avoidance of doubt, dividends accumulated and unpaid since the most recent Dividend Payment Date).

4.4 Conversion Value of Preferred Stock Tendered

Holders tendering the Preferred Stock for conversion shall be entitled to receive, for each share of Preferred Stock converted:

(a) an amount in cash (the “Cash Conversion Amount”) equal to the Issue Price; and

(b) a number of shares (the “Net Share Amount”) of Common Stock of the Issuer (the “Net Shares”) with a value determined by the Calculation Agent based on the Market Price equal to the product of (x) the greater of (i) the difference between the Market Price and the Conversion Price and (ii) zero and (y) the Number of Underlying Shares (the “Net Share Value”).

If the Issuer had elected in the written notice delivered to the converting Holder of the shares of Preferred Stock subject to conversion in accordance with Section 4.1 to make a cash payment, then the Issuer shall, in lieu of delivering the Net Shares, pay to such Holder in cash an amount equal to the Net Share Value.

Payment of the Cash Conversion Amount and all accumulated and unpaid dividends as provided in Section 4.3 and delivery of the Net Shares (or cash in an amount equal to the Net Share Value) shall be deemed to satisfy the Issuer’s obligation to pay the Liquidation Preference.

Anything herein to the contrary notwithstanding, in no event shall the Issuer be required to deliver more than 16,000,000 shares of Common Stock, subject to adjustment as provided herein (such number, including such adjustments, the “Maximum Number of Shares”).

4.5 Total Shares

If more than one share of the Preferred Stock shall be surrendered for conversion by the same Holder at the same time, the amount of the Cash Conversion Amount and

A-10

any accumulated and unpaid dividends and Net Share Amount (or the Net Share Value) shall be computed on the basis of the total number of shares of the Preferred Stock so surrendered.

4.6 Reservation of Shares; Shares to be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock

(a) The Issuer shall: (i) at all times reserve and keep available, free from preemptive rights and not reserved or kept available for issuance upon conversion or settlement of any other security or transaction, for issuance upon the conversion of shares of the Preferred Stock such number of its authorized but unissued shares of Common Stock, or shares of Common Stock held in treasury, as shall from time to time be sufficient if necessary to permit the conversion of all outstanding shares of the Preferred Stock into the Maximum Number of Shares; (ii) prior to the delivery of any securities that the Issuer shall be obligated to deliver upon conversion of the Preferred Stock, comply with all applicable federal and state laws and regulations that require action to be taken by the Issuer (including, without limitation, the registration or approval, if required, of any shares of Common Stock to be provided for the purpose of conversion of the Preferred Stock hereunder); and (iii) ensure that all shares of Common Stock delivered upon conversion of the Preferred Stock, upon delivery, be duly and validly issued and fully paid and nonassessable, free of all liens and charges, not subject to any preemptive rights, freely tradable and in unlegended form.

(b) The Issuer agrees to maintain, at any time at which there are any shares of Preferred Stock outstanding, the approval of the Exchange for the listing of such number of its authorized but unissued shares of Common Stock as shall be sufficient if necessary to permit the conversion of all outstanding shares of the Preferred Stock into the Maximum Number of Shares.

4.7 Adjustments to Conversion Price Upon Potential Adjustment Events

(a) Following the declaration by the Issuer of the terms of any Potential Adjustment Event, the Calculation Agent will determine whether such Potential Adjustment Event has a diluting or concentrative effect on the theoretical value of the Common Stock or an effect on the theoretical value of options on the Common Stock, and, if so, will (i) make the corresponding adjustment(s), if any, to the Conversion Price, as well as to any other variable relevant to the exercise, settlement, payment or other terms of the Preferred Stock as the Calculation Agent determines appropriate to account for the effect of such event on the Preferred Stock and (ii) determine the effective date(s) of the adjustment(s). Upon request of the Issuer, the Calculation Agent will provide documentation setting forth in reasonable detail the basis for such adjustments.

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

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

A-11

(ii) a distribution, issue or dividend to existing holders of the Common Stock of (A) such Common Stock, or (B) other share capital or securities granting the right to payment of dividends and/or the proceeds of liquidation of the Issuer equally or proportionately with such payments to holders of such Common Stock, or (C) share capital or other securities of another issuer acquired or owned (directly or indirectly) by the Issuer 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 determined by the Calculation Agent;

(iii) a cash dividend or cash distribution;

(iv) a call by the Issuer in respect of shares of Common Stock that are not fully paid;

(v) a repurchase by the Issuer or any of its Subsidiaries of shares of Common Stock whether out of profits or capital and whether the consideration for such repurchase is cash, securities or otherwise (except for such repurchases effected under the ASB Agreement);

(vi) in respect of the Issuer, 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 Issuer pursuant to a shareholder rights plan or arrangement directed against hostile takeovers that provides upon the occurrence of certain events for distribution of preferred stock, warrants, debt instruments or stock rights at a price below their market value, as 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

(vii) any other event that may have a diluting or concentrative effect on the theoretical value of the shares of Common Stock or an effect on the theoretical value of options on the Common Stock.

4.8 Consequences of Certain Events

(a) With respect to the following events, the definition and procedures of the Equity Definitions shall apply, mutatis mutandis, as specified:

(i) In the event of a Share-for-Share Merger Event, Alternative Obligation shall apply; provided, that notwithstanding the Equity Definitions, the Calculation Agent will determine in good faith if the relevant Merger Event affects the theoretical value of the Common Stock or the Preferred Stock and, if so, may in its reasonable discretion make the adjustments set forth in paragraph (A) under the definition of “Modified Calculation Agent Adjustment” in Section 12.2(e) of the Equity Definitions to the terms of the Preferred Stock to reflect the characteristics (including without limitation, the volatility, dividend practice and policy and liquidity) of the Common Stock.

A-12

(ii) In the event of a Share-for-Other Merger Event, Cancellation and Payment shall apply.

(iii) In the event of a Share-for-Combined Merger Event, Component Adjustment shall apply.

(iv) In the event of a Share-for Share Tender Offer, Share-for-Other Tender Offer or Share-for-Combined Tender Offer, Modified Calculation Agent Adjustment shall apply.

(v) In the event of a Nationalization, Insolvency or Delisting, Cancellation and Payment shall apply.

(b) For purposes of applying the definitions and procedures specified in Section 4.8(a), capitalized terms used in Section 4.8(a) and not otherwise defined shall have the meanings specified in the Equity Definitions, and the following terms used in the Equity Definitions shall have the following meanings for such purposes:

Equity Definitions Term		Meaning for Purposes of this Section 4.8
Shares		shares of Common Stock
Transaction		the Preferred Stock
Final Valuation Date		December 23, 2019
Trade Date		December 23, 2014

(c) If Cancellation and Payment shall apply, then, for purposes of applying the related definitions and procedures specified in Section 4.8(a), the Preferred Stock shall be deemed to be a Share Forward Transaction, the Holder shall be deemed to be the Determining Party, and Section 12.7(c) of the Equity Definitions shall be deemed to be replaced in its entirety with the following:

“The Issuer shall pay to the Holder of each share of Preferred Stock, in satisfaction of the Issuer’s obligation to pay the Liquidation Preference, the Cancellation Amount, in cash, subject to compliance with the Restricted Payment Provisions.”

(d) The provisions of this Section 4.8 shall be in addition to, and not to the exclusion of, any other rights that a Holder may have under this Certificate of Designations or otherwise.

(e) Upon the occurrence of a Change in Law, the provisions of Section 4.8(a)(iv) shall apply as if a Share-for-Share Tender Offer had occurred, with references to “Tender Offer” and “Tender Offer Date” in the Equity Definitions read to refer to “Change in Law” and “date of the Change in Law”, respectively, for such purposes.

A-13

4.9 Further Adjustment Provisions

(a) There shall be no adjustment of the Conversion Price:

(i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on Capital Stock of the Issuer and the investment of additional optional amounts in shares of Common Stock under any plan;

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director, officer or consultant benefit plan or program of or assumed by the Issuer or any Subsidiaries;

(iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in subsection (ii) and outstanding as of the date the Preferred Stock was first issued;

(iv) for a change in the par value of the Common Stock;

(v) for any repurchase by the Issuer or any of its Subsidiaries of shares of Common Stock at the then current market price of the Common Stock;

(vi) for any Potential Adjustment Event that will have an aggregate effect on the Preferred Stock (when aggregated with the effect of any other Potential Adjustment Event in respect of which no adjustment of the Conversion Price was made pursuant to this clause) that does not exceed $250,000;

(vii) for accumulated and unpaid dividends on the Preferred Stock or the Issuer’s Existing Preferred Stock;

(viii) for any regular, quarterly cash dividend or distribution that does not exceed $0.14 per share of Common Stock; or

(ix) for any event in which the Holders of Preferred Stock will otherwise participate in such event without conversion solely as a Holder of Preferred Stock.

(c) The Issuer may, from time to time, decrease the Conversion Price if the Board of Directors has made a determination that this decrease would be in the best

A-14

interests of the Issuer. Any such determination by the Board of Directors will be conclusive. In addition, the Issuer may decrease the Conversion Price if the Board of Directors deems it advisable to avoid or diminish any income tax to Holders of Common Stock resulting from any stock or rights distribution.

The Fundamental Change Purchase Notice shall state, among other things:

(ii) the number of shares of Preferred Stock to be purchased; and

(iii) that the Issuer shall purchase such Preferred Stock pursuant to the applicable provisions of the Preferred Stock and this Certificate of Designations.

(b) The delivery of such share of Preferred Stock to be purchased (together with all necessary endorsements) to the Transfer Agent at the office of such Transfer Agent shall be a condition to the receipt by the Holder of the Fundamental Change purchase price.

(c) Any purchase by the Issuer contemplated pursuant to the provisions of this Section 5.3 shall be consummated by the delivery of the consideration

5.4 Withdrawal of Fundamental Change Purchase Notice

(a) Notwithstanding anything herein to the contrary, any Holder of Preferred Stock delivering to the Transfer Agent the Fundamental Change Purchase Notice shall have the right to withdraw such Fundamental Change Purchase Notice in whole or as to a portion thereof at any time prior to the close of business on the Business Day before the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Transfer Agent in accordance with this Section 5.4. The Transfer Agent shall promptly notify the Issuer of the receipt by it of any Fundamental Change Purchase Notice or written withdrawal thereof. The written withdrawal shall specify, among other things:

(i) the certificate numbers for the shares of Preferred Stock in respect of which such notice of withdrawal is being submitted;

(ii) the number of shares of Preferred Stock with respect to which such notice of withdrawal is being submitted; and

(b) The Transfer Agent will promptly return to the respective Holders thereof any shares of Preferred Stock with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with this Certificate of Designations, in which case, upon such return, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

5.5 Effect of Fundamental Change Purchase Notice

Upon the receipt by the Transfer Agent of the Fundamental Change Purchase Notice, the Holder of the shares of Preferred Stock in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn) thereafter be entitled to receive the Fundamental Change Purchase Price with respect to such shares of Preferred Stock, subject to Section 5.3. Such Fundamental Change Purchase Price shall be paid to such Holder promptly following the later of (a) the Fundamental Change Purchase Date with respect to such shares of Preferred Stock and (b) the time of delivery of such shares of Preferred Stock to the Transfer Agent by the Holder thereof in the manner required by this Article 5.

Fundamental Change Purchase Notice has first been validly withdrawn as specified in Section 5.4.

The manner in which the deposit required by this Section 5.6 is made by the Issuer shall be at the option of the Issuer; provided, however, that such deposit shall be made in a manner such that the Transfer Agent shall have immediately available funds on the date of deposit. If the Transfer Agent holds cash sufficient to pay the Fundamental Change Purchase Price of any share of Preferred Stock for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with this Certificate of Designations on the Business Day following the Fundamental Change Purchase Date then, effective immediately after such Fundamental Change Purchase Date (regardless of whether or not delivery of such shares of Preferred Stock to the Transfer Agent by the Holder thereof in the manner required by this Article 5 is made), such shares of Preferred Stock will cease to be outstanding, dividends will cease to accumulate and all other rights of the Holder shall terminate (other than the right to receive the Fundamental Change Purchase Price as aforesaid).

Upon surrender of the certificate or certificates representing shares of Preferred Stock that is or are purchased in part, the Issuer shall execute and the Transfer Agent shall authenticate and deliver to the Holder, a new certificate or certificates representing shares of the Preferred Stock in an amount equal to the unpurchased portion of the shares of Preferred Stock surrendered for partial purchase.

5.8 Repayment to the Issuer

The Transfer Agent shall return to the Issuer any cash that remains unclaimed for two years, subject to applicable unclaimed property law, together with interest, if any, thereon held by them for the payment of the Fundamental Change purchase price; provided, however, that to the extent that the aggregate amount of cash deposited by the Issuer pursuant to this Section 5.8 exceeds the aggregate purchase price of the Preferred Stock or portions thereof that the Issuer is obligated to purchase as of the Fundamental Change Purchase Date, then on the Business Day following the Fundamental Change Purchase Date, the Transfer Agent shall return any such excess to the Issuer.

6.3 After payment of the full amount of the Liquidation Preference to which Holders of shares of the Preferred Stock are entitled (including all accumulated and unpaid dividends to which Holders of the shares of Preferred Stock are entitled), the Holders of shares of the Preferred Stock will have no right or claim to any of the remaining assets of the Issuer.

6.4 Neither the voluntary sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all of the property or assets of the Issuer nor the consolidation, merger or amalgamation of the Issuer with or into one or more entities or the consolidation, merger or amalgamation of one or more entities with or into the Issuer will be deemed to be a voluntary or involuntary liquidation, dissolution or winding up of the Issuer, unless such sale, conveyance, exchange or transfer shall be in connection with a liquidation, dissolution or winding up of the business of the Issuer.

6.5 Notwithstanding the foregoing, the Issuer is not required to set aside any funds to protect the Liquidation Preference of the shares of Preferred Stock.

7. Voting Rights

7.2 Except as set forth in this Certificate of Designations, the creation, authorization or issuance of any shares of Junior Stock or Parity Stock or an increase or decrease in the amount of authorized Common Stock or Preferred Stock, shall not require the consent of the Holders of the Preferred Stock and shall not be deemed to affect adversely the rights, preferences, privileges or voting rights of Holders of shares of the Preferred Stock.

Promptly following the end of any Stock Borrow Disruption Period, as determined by the Calculation Agent, the dividend rate shall reset to 2.822%. The “Expected Borrow Cost” is 0.25% per annum.

The Certificate of Amendment has been duly authorized by the Issuer and has been filed with the Secretary of State of the State of Delaware and has become effective in accordance with the General Corporation Law of the State of Delaware (the “DGCL”), and each of the rights, powers and preferences, and qualifications, limitations and restrictions of the Shares set forth in the Certificate of Designations as amended by the Certificate of Amendment are authorized by and do not conflict with the DGCL.

4. The Amendment Agreement has been duly authorized, executed and delivered by the Issuer and is a valid and binding obligation of the Issuer and is enforceable against the Issuer in accordance with its terms.

5. The shares of the [ ]% Perpetual Convertible Preferred Stock (the “Shares”) have been duly authorized and such Shares are validly issued, fully paid and nonassessable.

6. The Shares will be convertible into shares of Common Stock, par value $0.01 per share, of the Issuer (the “Common Stock”) in accordance with the terms of the Certificate of Designations as amended by the Certificate of Amendment. The shares of Common Stock, if any, to be issued by the Issuer upon conversion of the Shares in accordance with the terms of the Certificate of Designations have been duly authorized and, when appropriate certificates representing such shares of Common Stock are duly countersigned by the Issuer’s transfer agent/registrar and issued in accordance with the terms of the Certificate of Designations, such shares of Common Stock will be validly issued, fully paid and nonassessable. The issuance of such shares of Common Stock is not subject to any preemptive rights under the terms of the statute under which the Issuer is incorporated, under the Issuer’s Certificate of Incorporation or under any contractual provision of any document listed on Exhibit A.

7. The execution and delivery of the Transaction Documents by the Issuer and the performance by the Issuer of its obligations thereunder do not and will not (i) conflict with or violate any of the terms or provisions of the Issuer’s Certificate of Incorporation or Bylaws, (ii) result in any breach of any of the terms and provisions of, or constitute a default (or an event which with notice or lapse of time, or both, would constitute a default) under any Specified Contract (it being expressly understood that in each case we express no opinion as to compliance with any financial covenant or test or cross-default provision in any Specified Contract), (iii) violate or conflict with any judgment, decree or order identified to us by the Issuer (we note that none were identified) of any court or any judicial, regulatory or other legal or governmental agency or body having jurisdiction

B-2

over the Issuer or any of the Issuer’s subsidiaries or any of their properties or (iv) violate any Specified Laws (as defined below) which, in our experience, are normally applicable to both general business corporations that are not engaged in regulated business activities and to transactions of the type contemplated by the Amendment Agreement (but without having made any special investigation as to other laws), except in each of the cases of clauses (ii) and (iii), for any such conflict, breach, violation or default which has been waived by the party or parties with power to waive such conflict, breach, violation or default. (The advice in this paragraph is referred to herein as the “No Conflicts Opinion”).

8. No consent, waiver, approval, authorization or order of any court or governmental authority is required for the consummation by the Issuer of the transactions contemplated by the Transaction Documents, except such as may be required under the Securities Act, the security or Blue Sky laws of the various states and any statutes or rules relating to the regulation of energy production (and the rules and regulations thereunder), as to which we express no opinion in this paragraph. (The advice in this paragraph is referred to herein as the “No Consent Opinion”).

9. The Issuer is not, nor immediately after the sale of the Shares to the Purchaser and application of the net proceeds therefrom will be, an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

ooooooooo

We have not undertaken any search of court records or undertaken any other investigation to determine the facts upon which the advice in this letter is based.

We have assumed for purposes of this letter: each document we have reviewed for purposes of this letter is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, and all signatures on each such document are genuine; that the Amendment Agreement and every other agreement we have examined for purposes of this letter constitutes a valid and binding obligation of each party to that document (other than the Issuer) and that each such party has satisfied all legal requirements that are applicable to such party to the extent necessary to entitle such party to enforce such agreement (except that we make no such assumption with respect to the Issuer); and that you have acted in good faith and without notice of any fact which has caused you to reach any conclusion contrary to any of the advice provided in this letter. We have also made other assumptions which we believe to be appropriate for purposes of this letter.

In preparing this letter we have relied without independent verification upon: (i) information contained in certificates obtained from governmental authorities; (ii) factual information represented to be true in the Amendment Agreement and other documents specifically identified at the beginning of this letter as having been read by us; (iii) factual information provided to us by the Issuer or its representatives; and (iv) factual information we

B-3

have obtained from such other sources as we have deemed reasonable. We have assumed that there has been no relevant change or development between the dates as of which the information cited in the preceding sentence was given and the date of this letter and that the information upon which we have relied is accurate and does not omit disclosures necessary to prevent such information from being misleading. For purposes of numbered paragraph 1, we have relied exclusively on a certificate issued by governmental authorities of the State of Delaware, and such opinion is not intended to provide any conclusion or assurance beyond that conveyed in the certificate.

While we have reviewed certain corporate records and other documents specifically identified at the beginning of this letter as having been read by us, we have not undertaken any other investigation to determine the facts upon which the advice in this letter is based. We confirm that we do not have knowledge that has caused us to conclude that our reliance and assumptions cited in the two immediately preceding paragraphs are unwarranted.

Whenever this letter provides advice about (or based upon) our knowledge of any particular information or about any information which has or has not come to our attention such advice is based entirely on the conscious awareness at the time this letter is delivered on the date it bears by the lawyers with Xxxxxxxx & Xxxxx LLP at that time who spent substantial time representing the Issuer in connection with the sale effected pursuant to the Amendment Agreement after consultation with such other lawyers at Xxxxxxxx & Xxxxx LLP who have spent substantial time representing the Issuer on other matters since December 31, 2013.

Each opinion (an “enforceability opinion”) in this letter that any particular contract is a valid and binding obligation or is enforceable in accordance with its terms is subject to: (i) the effect of bankruptcy, insolvency, fraudulent conveyance and other similar laws and judicially developed doctrines in this area such as substantive consolidation and equitable subordination; (ii) the effect of general principles of equity; and (iii) other commonly recognized statutory and judicial constraints on enforceability including statutes of limitations. “General principles of equity” include but are not limited to: principles limiting the availability of specific performance and injunctive relief; principles which limit the availability of a remedy under certain circumstances where another remedy has been elected; principles requiring reasonableness, good faith and fair dealing in the performance and enforcement of an agreement by the party seeking enforcement; principles which may permit a party to cure a material failure to perform its obligations; and principles affording equitable defenses such as waiver, laches and estoppel. It is possible that terms in a particular contract covered by our enforceability opinion may not prove enforceable for reasons other than those explicitly cited in this letter should an actual enforcement action be brought, but (subject to all the exceptions, qualifications, exclusions and other limitations contained in this letter) such unenforceability would not in our opinion prevent the party entitled to enforce that contract from realizing the principal benefits purported to be provided to that party by the terms in that contract which are covered by our enforceability opinion.

B-4

Our advice on every legal issue addressed in this letter is based exclusively on the internal law of the State of New York, the General Corporation Law of the State of Delaware, the Delaware Limited Liability Company Act, and the federal laws of the United States (except that we do not opine as to the federal securities laws with respect to the No Conflicts Opinion and the No Consent Opinion), without our having made any investigation as to the applicability of any specific law unless such advice specifically references a specific law (the “Specified Laws”), and represents our opinion as to how that issue would be resolved were it to be considered by the highest court in the jurisdiction which enacted such law. None of the opinions or other advice contained in this letter considers or covers, and the term “Specified Laws” does not include: (i) any antifraud laws, rules or regulations; (ii) any state securities (or “blue sky”) laws, rules or regulations; (iii) any laws, rules or regulations of the Financial Industry Regulatory Authority, Inc.; (iv) any federal, state, local or foreign laws, statutes, government rules or regulations or decisions governing the rates charged by, or the financial or organizational regulation of, electric utilities, transmission and distribution utilities, retail electric utilities, retail steam, hot water and/or chilled water utilities, public utilities, public service companies, or other similar entities; and (v) any laws, statutes, governmental rules or regulations or decisions which in our experience are not usually considered for or covered by opinions like those contained in this letter or are not generally applicable to transactions of the kind covered by the Transaction Documents including any regulatory laws or requirements specific to the industry in which you or the Issuer is engaged.

In addition, none of the opinions or other advice contained in the letter covers or otherwise addresses any of the following types of provisions which may be contained in the Transaction Documents: (i) provisions mandating contribution towards judgments or settlements among various parties; (ii) waivers of benefits and rights to the extent they cannot be waived under applicable law; (iii) provisions providing for liquidated damages, late charges and prepayment charges, in each case if deemed to constitute penalties; (iv) provisions which might require indemnification or contribution in violation of general principles of equity or public policy, including, without limitation, indemnification or contribution obligations which arise out of the failure to comply with applicable state or federal securities laws; (v) laws and regulations governing restrictions on distributions; or (vi) requirements in the Transaction Documents specifying that provisions thereof may only be waived in writing (these provisions may not be valid, binding or enforceable to the extent that an oral agreement or an implied agreement by trade practice or course of conduct has been created modifying any provision of such documents). This letter does not cover any other laws, statutes, governmental rules or regulations or decisions which in our experience are not usually considered for or covered by opinions like those contained in this letter or are not generally applicable to transactions of the kind covered by the Transaction Documents. We express no opinion as to what law might be applied by any courts to resolve any issue addressed by our opinion and we express no opinion as to whether any relevant difference exists between the laws upon which our opinions are based and any other laws which may actually be applied to resolve issues which may arise. The manner in which any particular issue would be treated in any actual court case would depend in part on facts and circumstances particular to the case and would also depend on how the court

B-5

involved chose to exercise the wide discretionary authority generally available to it. This letter is not intended to guarantee the outcome of any legal dispute that may arise in the future.

We note that certain of the Specified Contracts are governed by laws other than the Specified Laws. Our advice expressed herein is based on the plain language of such Specified Contracts, without regard to the interpretation of such language under such other laws, and we do not assume any responsibility with respect to the effect on the opinions set forth herein of any interpretation thereof inconsistent with such understanding.

This letter speaks as of the time of its delivery on the date it bears. We do not assume any obligation to provide you with any subsequent opinion or advice by reason of any fact about which we did not have knowledge at that time, by reason of any change subsequent to that time in any law other governmental requirement or interpretation thereof covered by any of our opinions or advice, or for any other reason.

This letter may be relied upon by you only for the purpose served by the provision in the Amendment Agreement cited in the initial paragraph of this letter in response to which it has been delivered. Without our written consent: (i) no person other than you may rely on this letter for any purpose; (ii) this letter may not be cited or quoted in any financial statement, offering memorandum, private placement memorandum or other similar document; (iii) this letter may not be cited or quoted in any other document or communication which might encourage reliance upon this letter by any person or for any purpose excluded by the restrictions in this paragraph; and (iv) copies of this letter may not be furnished to anyone for purposes of encouraging such reliance.

	Very truly yours,

Ladies and Gentlemen:

I am Executive Vice President and General Counsel of NRG Energy, Inc., a Delaware corporation (the “Company”), and provide this letter in response to the requirements of Section 5(c) of the Amendment Agreement, dated as of December [ ], 2014 (the “Amendment Agreement”), between the Company and Credit Suisse Capital LLC (“CS” and herein being called “you”). Every term which is defined or given a special meaning in the Purchase Agreement (as defined below) and which is not given a different meaning in this letter has the same meaning whenever it is used in this letter as the meaning it is given in the Purchase Agreement.

I have reviewed executed counterparts of the Amendment Agreement, the Stock Purchase Agreement, dated August 11, 2005, between the Company and Credit Suisse First Boston Capital LLC (the “Purchase Agreement”), the Certificate of Designations (the “Certificate of Designations”), dated August 11, 2005, establishing the 3.625% Perpetual Convertible Preferred Stock, and the Certificate of Amendment to the Certificate of Designations, dated as of the date hereof, establishing the [ ]% Perpetual Convertible Preferred Stock (the “Certificate of Amendment”). For purposes hereof, the Purchase Agreement, the Amendment Agreement, and the Certificate of Amendment, each in the form reviewed by me for purposes of this opinion letter, are referred to herein, collectively, as the “Transaction Documents.”

Subject to the assumptions, qualifications, exclusions and other limitations which are Identified in this letter, I advise you, and with respect to each legal issue addressed in this letter, it is my opinion, that:

1. I have no knowledge about any legal or governmental proceeding that is pending or threatened against the Company or its subsidiaries that has caused me to conclude that such proceeding is required by Item 103 of Regulation S-K (“Regulation S-K”) under the Securities Act of 1933, as amended (the “Securities Act”), to be described in the Exchange Act Reports but that is not so described.

2. The issuance of shares of the Company’s par value $0.01 Common Stock, if any, pursuant to the conversion provisions contained in the Certificate of Designations, as amended by the Certificate of Amendment, is not subject to any preemptive

rights under any contractual provision of any documents of which I have knowledge.

In rendering this opinion, I have examined (i) originals or confirmed copies of the Amended and Restated Certificate of Incorporation, as amended, and Second Amended and Restated Bylaws of the Company, (ii) originals or copies of the resolutions of the board of directors and the finance and risk management committee of the board of directors of the Company approving the Transaction Documents and (iii) such corporate records, agreements and instruments of the Company, and such other documents, records and matters of law as I have deemed necessary for purposes of this opinion. With respect to all documents examined by me, I have assumed that (i) all signatures on documents examined by me are genuine, (ii) all documents submitted to me as originals are authentic and (iii) all documents submitted to me as copies conform with the original copies of those documents.

I am admitted to the bar of the District of Columbia and, as applicable, am opining herein on the General Corporation Law of the State of Delaware. I advise you that issues addressed by this letter may be governed in whole or in part by other laws, but I express no opinion as to whether any relevant difference exists between the laws upon which my opinions are based and any other laws which may actually govern.

My advice on each legal issue addressed in this letter represents my opinion as to how that issue would be resolved were it to be considered by the highest court of the jurisdiction upon whose law my opinion on that issue is based. The manner in which any particular issue would be treated in any actual court case would depend in part on facts and circumstances particular to the case, and this letter is not intended to guarantee the outcome of any legal dispute which may arise in the future.

This letter speaks as of the time of its delivery on the date it bears. I do not assume any obligation to provide you with any subsequent opinion or advice by reason of any fact about which I did not have actual knowledge at that time, by reason of any change subsequent to that time in any law covered by any of my opinions, or for any other reason.

You may rely upon this letter only for the purposes cited in the initial paragraph of this letter in response to which it has been delivered. Without my written consent: (i) no person other than you may rely on this letter for any purpose; (ii) this letter may not be cited or quoted in any financial statement, prospectus, private placement memorandum or other similar document; (iii) this letter may not be cited or quoted in any other document or communication which might encourage reliance upon this letter by any person or for any purpose excluded by the restrictions in this paragraph; and (iv) copies of this letter may not be furnished to anyone for purposes of encouraging such reliance.
