          (c)     No later than 9:00AM, New York City time on each Scheduled Trading Day in the Reference Period, Issuer shall specify to Purchaser a Daily Notional Number of Shares (which shall equal the Daily Notional Number of Shares specified by NRG Common Stock Finance II for such Scheduled Trading Day pursuant to the NRG CSF II Note Purchase Agreement), subject to the following guidelines:

          (1)     the Daily Notional Number of Shares for such Scheduled Trading Day, when aggregated with any purchases made on such day by the Company or any “affiliated purchaser” (as such term is defined in Rule 10b-18 under the Securities Exchange Act of 1934, as amended (“Rule 10b-18”)) of the Company other than NRG Common Stock Finance II, shall not exceed the number of shares of NRG Common Stock that the Company could have purchased on that day pursuant to the safe harbor provisions of Rule 10b-18 (determined, for purposes of this Agreement, by excluding from any calculation of ADTV (as such term is used in Rule 10b-18) any purchase or sale of shares of NRG Common Stock effected by Purchaser or an affiliate of Purchaser in connection with any Transaction Document that would otherwise have been included in such calculation of ADTV);

          (2)     the Daily Notional Number of Shares for such Scheduled Trading Day shall not cause the Notional Amount to exceed $500,000,000; and

          (3)     Issuer acknowledges that, as of the date of this Agreement, it intends (but without being legally bound to do so), to the extent not inconsistent with the requirements in the immediately preceding clause (1), to select the Daily Notional Number of Shares for each Scheduled Trading Day in the Reference Period so that the Notional Amount equals $500,000,000 on or prior to the end of the Reference Period. If the Notional Amount as of the end of the Reference Period is less than $500,000,000, the parties shall work together in good faith to execute such documents, substantially similar to the Transaction Documents, as may be required to enter into transactions substantially similar to those contemplated by the Transaction Documents so that the aggregate notional amounts of all such transactions equals $500,000,000.

          (d)     Purchaser will make payment to Issuer in immediately available funds by wire transfer to an account designated by Issuer on each day that is one Settlement Cycle following each Exchange Business Day in the Reference Period (each such date of payment, a “Funding Date”) in an amount equal to the Daily Funding Amount for such Funding Date.

          (e)     On the last Exchange Business Day of the Reference Period, the Calculation Agent will deliver to the parties a pricing confirmation setting forth the final pricing terms of the Note issued on the Issue Date (a “Pricing Confirmation”), duly completed and substantially in the form of Exhibit B hereto. Upon receipt of the Pricing Confirmation, the parties will each execute a copy thereof; provided that regardless of whether either party executes a copy of the Pricing Confirmation, the terms set forth in the Pricing Confirmation shall be binding on the parties absent manifest error, unless such party notifies the other party that it reasonably believes that an error has been made in the computation of such terms within three Business Days of receipt thereof, in which case the parties shall work together to determine the correct terms.

          SECTION 4.   Payment and Delivery at Maturity.   (a) On the Maturity Date for each Component of each Note, Issuer shall make a payment to the Noteholder of such Note in Cash equal to the Principal Amount of such Component as of such Maturity Date.

          (b)     In addition to payment of principal as provided in Section 4(a), each Noteholder shall have the right to exchange each Component of each Note held by such Noteholder for the 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 Maturity Date for each Component of each Note so exchanged, Issuer shall (in addition to the Principal Amount set forth in Section 4(a)) make a payment and/or a delivery to such Noteholder of (i) an amount in cash equal to the product of the 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 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 the number of shares so delivered in respect of any Component of any Note shall not exceed 77.3980% of the Number of Underlying Shares for such Component.

          (c)     Issuer may, by written notice to all Noteholders 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 Notes issued hereunder. For the avoidance of doubt, if Issuer does not so specify a Cash Settlement Percentage, the Cash Settlement Percentage shall be zero.

          SECTION 5.   Payments.   (a) All payments of, or in respect of, principal or any other payment on any Note shall be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts by wire transfer of immediately available funds to an account designated by the Noteholder of such Note.

          (b)     All payments of, or in respect of, principal or any other payment on the Notes made by Issuer hereunder will be made without withholding or deduction for, or on account of, any present or future taxes, duties, fines, penalties, assessments or other governmental charges of whatsoever nature (or interest on any taxes, duties, fines, penalties, assessments or other governmental charges of whatsoever nature) imposed, levied, collected, withheld or assessed by, within or on behalf of any jurisdiction in which Issuer is organized, deemed to reside or engaged in business for tax purposes, or any jurisdiction from or through which any amount is paid by Issuer or any political subdivision or governmental authority thereof or therein having power to tax other than Excluded Taxes (collectively “Taxes”), unless such withholding or deduction is required by law. If any such Taxes shall at any time be required in respect of the payment of any amounts by Issuer under any Note, Issuer will pay to each Noteholder such additional amounts as may be necessary to ensure that the amounts received by such Noteholder after such withholding or deduction shall equal the amounts of principal and interest which would have been receivable in respect of such Note in the absence of such withholding or deduction.

          (c)     To the extent permitted by applicable law, each Noteholder that is not a United States person within the meaning of Code section 7701(a)(30) (a “Non-U.S. Participant”) shall deliver to Issuer on or prior to the Issue Date (or in the case of a Noteholder that is an assignee, on the date of such assignment to such Noteholder) two accurate and complete original signed copies of IRS Form W-8BEN, W-8ECI, or
W-8IMY (or any successor or other applicable form prescribed by the IRS) certifying to such Noteholder’s entitlement to a complete exemption from United States withholding tax on interest payments to be made hereunder.

If a Noteholder that is a Non-U.S. Participant is claiming a complete exemption from withholding on interest pursuant to Sections 871(h) or 881(c) of the Code, such Noteholder shall deliver (along with two accurate and complete original signed copies of IRS Form W-8BEN) a certificate in form and substance reasonably acceptable to Issuer (any such certificate, a “Withholding Certificate”). If any Noteholder determines, as a result of any change in applicable law, regulation or treaty, or in any official application or interpretation thereof, that it is unable to submit to Issuer any form or certificate that such Noteholder is obligated to submit pursuant to this subsection (c) or that such Noteholder is required to withdraw or cancel any such form or certificate previously submitted or any such form or certificate otherwise becomes ineffective or inaccurate, such Noteholder shall promptly notify Issuer of such fact and such Noteholder shall to that extent not be obligated to provide any such form or certificate and will be entitled to withdraw or cancel any affected form or certificate, as applicable. Each Noteholder that is not a Non-U.S. Participant (other than any such Noteholder which is taxed as a corporation for U.S. federal income tax purposes) shall provide two properly completed and duly executed copies of IRS Form W-9 (or any successor or other applicable form) to the Company certifying that such Noteholder is exempt from United States backup withholding tax. Notwithstanding any other provision of this paragraph (c) if a Noteholder fails to provide a Withholding Certificate providing for a complete exemption from withholding for whatever reason upon becoming party to this agreement, then such Noteholder shall be deemed not to have complied with this paragraph (c) for purposes of subsection (c) under the definition for Excluded Taxes.

          SECTION 6.   Representations and Warranties of Issuer.   Issuer represents and warrants to Purchaser, as of the Issue Date, as of each Scheduled Trading Day during the Reference Period for which the Daily Notional Number of Shares is greater than zero and, with respect to the representations and warranties set forth in clauses (t) through (dd), on each Business Day that Collateral is delivered by Issuer

          (r)     it (A) has timely filed, caused to be timely filed or will timely file or cause to be timely filed all material tax returns that are required to be filed by it as of the date hereof, if any, and (B) has paid all material taxes shown to be due and payable on said returns or on any assessment made against it or any of its property, if any, and all other material taxes, assessments, fees, liabilities or other charges imposed on it or any of its property by any governmental authority, unless in each case the same are being contested in good faith (for purposes of determining whether a tax return has been timely filed, any extensions shall be taken into account);

          (s)     all representations and warranties of Issuer under all Transaction Documents are true and correct;

          (t)     it has not (A) created or permitted to exist any Lien upon or with respect to the Collateral, (B) sold or otherwise disposed of, or granted any option with respect to, any of the Collateral or (C) entered into or consented to any agreement (other than, in the case of clause (x), this Agreement) (x) that restricts in any manner the rights of any present or future owner of any Collateral with respect thereto or (y) pursuant to which any person other than Issuer, Purchaser and any securities intermediary through whom any of the Collateral is held (but in the case of any such securities intermediary only in respect of Collateral held through it) has or will have Control in respect of any Collateral;

          (u)     other than financing statements or other similar or equivalent documents or instruments with respect to the security interests in the Collateral created by Section 20 below, no financing statement, security agreement or similar or equivalent document or instrument covering all or any part of the Collateral is on file or of record in any jurisdiction in which such filing or recording would be effective to perfect a Lien, security interest or other encumbrance of any kind on such Collateral;

          (v)     all Collateral consisting of securities and all financial assets underlying Collateral consisting of security entitlements (each as defined in Section 8-102 of the UCC) at any time pledged hereunder is and will be issued by an issuer organized under the laws of the United States, any State thereof or the District of Columbia and is and will be (i) certificated (and the certificate or certificates in respect of such securities or financial assets are and will be located in the United States) and registered in the name of Issuer or held through a securities intermediary whose securities intermediary’s jurisdiction (within the meaning of Section 8-110(e) of the UCC) is located in the United States or (ii) uncertificated and either registered in the name of Issuer or held through a securities intermediary whose securities intermediary’s jurisdiction (within the meaning of Section 8-110(e) of the UCC) is located in the United States; provided that this representation shall not be deemed to be breached if, at any time, any such Collateral is issued by an issuer that is not organized under the laws of the United States, any State thereof or the District of Columbia, and the parties hereto agree to procedures or amendments hereto necessary to enable Purchaser to maintain a valid and continuously perfected security interest in such Collateral, in respect of which Purchaser will have Control, subject to no prior Lien (and the parties hereto agree to negotiate in good faith any such procedures or amendments);

          (j)     Issuer shall have furnished to Purchaser such further certificates and documents as Purchaser shall reasonably request (including an officer’s certificate of an officer of the Company) to the effect that, during the Reference Period, the Company could have purchased shares of NRG Common Stock with an aggregate purchase price equal to the aggregate amount of Cash contributed by the Company to Issuer pursuant to the Issuer Common Equity Interest Purchase Agreement in compliance with Delaware law;

          SECTION 11.   Events of Default.   The occurrence of any of the following events shall constitute an event of default (an “Event of Default”) hereunder and under each Note:

          (a)     failure by Issuer to make, when due, any payment (including, without limitation, of principal) or delivery under this Agreement, any Note or any other Transaction Document to which it is a party;

          (b)     failure by Issuer to perform when due its obligations set forth in Section 8(c) or Section 19(a);

          (c)     failure by Issuer to comply with or perform any agreement or obligation (other than an obligation to make any payment or delivery referred to in Section 11(a) or an obligation referred to in Section 11(b)) under this Agreement, any Note or any other Transaction Document to be complied with or performed by it in accordance with this Agreement, any Note or any other Transaction Document if such failure is not remedied on or before the third Business Day after notice of such failure is given to Issuer;

          (d)     this Agreement, any Note or any other Transaction Document ceases to be in full force and effect, or is declared by a court of competent jurisdiction to be null and void, invalid or unenforceable in any material respect, or Issuer or any Affiliate of Issuer party to any Transaction Document disaffirms, disclaims, repudiates or rejects, in whole or in part, or challenges the validity of, this Agreement any Note or any other Transaction Document;

          (e)     a representation made or repeated by Issuer or any Affiliate of Issuer party to any Transaction Document in this Agreement or any other Transaction Document proves to have been incorrect or misleading in any material respect when made or repeated or deemed to have been made or repeated;

          (f)     Issuer or the Company is (1) dissolved (other than pursuant to a consolidation, amalgamation or merger); (2) becomes insolvent or is unable to pay its debts or fails or admits in writing its inability generally to pay its debts as they become due; (3) makes a general assignment, arrangement or composition with or for the benefit of its creditors; (4) institutes or has instituted against it a proceeding seeking a judgment of insolvency or bankruptcy or any other relief under any bankruptcy or insolvency law or other similar law affecting creditors’ rights, or a petition is presented for its winding-up or liquidation, and, in the case of any such proceeding or petition instituted or presented against it, such proceeding or petition (A) results in a judgment of insolvency or bankruptcy or the entry of an order for relief or the making of an order for its winding-up or liquidation or (B) is not dismissed, discharged, stayed or restrained in each case within 15 days of the institution or presentation thereof; (5) has a resolution passed for its winding-up, official management or liquidation (other than pursuant to a consolidation, amalgamation or merger); (6) seeks or becomes subject to the appointment of an administrator, provisional liquidator, conservator, receiver, trustee custodian or other similar official for it or for all or substantially all its assets; (7) has a secured party take possession of all or substantially all its assets or has a distress, execution attachment, sequestration or other legal process levied, enforced or sued on or against all or substantially all its assets and such secured party maintains possession, or any such process is not dismissed, discharged, stayed or restrained, in each case within 15 days thereafter; (8) causes or is subject to any event with respect to it which, under the applicable laws of any jurisdiction, has an analogous effect to any of the events specified in clauses (1) to (7) (inclusive); or (9) takes any action in furtherance of, or indicating its consent to, approval of, or acquiescence in, any of the foregoing acts;

          (g)     due to the adoption of, or any change in, any applicable law after the date hereof, or due to the promulgation of, or any change in, the interpretation by any court, tribunal or regulatory authority with competent jurisdiction of any applicable law after such date, it becomes unlawful for Issuer or any Affiliate of Issuer party to any Transaction Document (i) to perform any absolute or contingent obligation to make a payment or delivery, or to receive a payment or delivery in respect of this Agreement or any other Transaction Document or to comply with any other material provision of this Agreement or any other Transaction Document or (2) to perform any contingent or other obligation which Issuer or such Affiliate has under this Agreement or any other Transaction Document; and

          (h)     any legal proceeding shall have been instituted or any other event shall have occurred or condition shall exist that would reasonably be expected to have a material adverse effect on (i) the ability of Issuer or any Affiliate of Issuer party to any Transaction Document to perform its obligations under this Agreement, any Note or any other Transaction Document, or (ii) the validity or binding effect of any agreement of Issuer or such Affiliate under this Agreement, any Note or any other Transaction Document.

          SECTION 12.   Remedies Upon Default.   (a) Upon the occurrence, and during the continuance of, any Event of Default, the Noteholder of any Notes issued hereunder may declare the Termination Amount of any or all of the Components comprising any or all of such Notes to be immediately due and payable and exercise any and all remedies available to it under this Agreement and the Notes; provided that in the case of any of the events specified in Section 11(f), without any notice, the Termination Amount of all Components comprising all Notes issued hereunder shall become immediately due and payable without presentment, demand for payment, protest, notice of nonpayment or other notice of any kind, all of which are hereby waived by Issuer.

          (b)     Except as expressly set forth herein, upon payment and delivery of the Termination Amount for any Component so declared due and payable, all of Issuer’s obligations in respect of the payment and/or delivery pursuant to Section 4 shall be deemed satisfied with respect to such Component.

          (c)     Upon the occurrence, and during the continuance of, any Event of Default, any Noteholder is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to, and Issuer agrees that any Noteholder shall have the right to, (i) set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Noteholder to or for the credit or the account of Issuer (including without limitation pursuant to any Transaction Document) against any and all of the obligations of Issuer now or hereafter existing under this Agreement and the Notes held by such Noteholder, and (ii) set-off any obligation that such Noteholder or any Affiliate of such Noteholder may have to Issuer against any right such Noteholder or any of its Affiliates may have against Issuer (including without limitation any right to receive a payment or delivery pursuant to any provision of this Agreement and the Notes), in each case irrespective of whether or not such Noteholder shall have made any demand under this Agreement or the Notes or any such agreement and although such obligations may be unmatured. In the case of a set-off of any obligation to release, deliver or pay assets against any right to receive assets of the same type, such obligation and right shall be set-off in kind. In the case of a set-off of any obligation to release, deliver or pay assets against any right to receive assets of any other type, the value of each of such obligation and such right shall be reasonably determined by the Calculation Agent and the result of such set-off shall be that the net obligor shall pay or deliver to the other party an amount of cash or assets, at the net obligor’s option, with a value (determined, in the case of a delivery of assets, by the Calculation Agent) equal to that of the net obligation.

In determining the value of any obligation to release or deliver any securities or right to receive any securities, the value at any time of such obligation or right shall be determined by reference to the market value of such securities at such time. If an obligation or right is unascertained at the time of any such set-off, the Calculation Agent may in good faith estimate the amount or value of such obligation or right, in which case set-off will be effected in respect of that estimate, and the relevant party shall account to the other party at the time such obligation or right is ascertained. The rights of any Noteholder under this Section 12(c) are in addition to other rights and remedies (including, without limitation, other rights of set-off) that any Noteholder may have as a matter of law, pursuant to contract or otherwise.

          SECTION 13.   Extraordinary Events.   (a) If the Calculation Agent has reasonably determined that an Extraordinary Event has occurred, then it shall so notify the parties, and the Noteholder of such Note may, in its sole discretion, designate any Trading Day as the Accelerated Maturity Date for any or all of the Components comprising such Note (each, a “Relevant Component”) in whole or in part. If such Noteholder exercises its right to designate the Accelerated Maturity Date for any Relevant Component in part, it shall also designate a percentage (the “Acceleration Percentage”) representing the portion of such Relevant Component being accelerated, and such Relevant Component shall be deemed to be two Components with terms identical to those of such Relevant Component, except that the first such Component (the “Accelerated Component”) shall have an Initial Principal Amount equal to the product of the Acceleration Percentage and the Initial Principal Amount of such Relevant Component, and the second such Component (the “Surviving Component”) shall have an Initial Principal Amount equal to the product of (x) one minus the Acceleration Percentage and (y) the Initial Principal Amount of such Relevant Component. Issuer shall pay the Termination Amount for all Relevant Components (or, in the case of a partial acceleration, all Accelerated Components) on the Accelerated Maturity Date. In the case of a partial acceleration, each Surviving Component shall survive and continue to be outstanding and in full force and effect hereunder.

          (b)     Except as expressly set forth herein, upon payment and delivery of the Termination Amount for any Component for which an Accelerated Maturity Date has so been declared, all of Issuer’s obligations in respect of the payment and/or delivery pursuant to Section 4 shall be deemed satisfied with respect to such Component.

          SECTION 14.   Adjustment Event.   (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 14(b), to the Notional Number of Shares) to compensate Noteholders 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.

          SECTION 15.   Increased Cost of Hedging and Increased Costs.   The Calculation Agent may reduce the Threshold Price for any Note 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 Note.

          SECTION 16.   Optional Unwind.   (a) Issuer may, by not less than 10 nor more than 30 Business Days prior written notice to all Noteholders, and subject to the execution by Issuer of such documentation as may be reasonably required based on advice of counsel to the Noteholders, designate an unwind date (an “Unwind Date”) for any or all of the Components comprising any Note (each, a “Relevant Component”) outstanding at the time. If Issuer elects to unwind any Relevant Component in part, it shall also designate a percentage (the “Unwind Percentage”) representing the portion of such Relevant Component to be unwound, and such Relevant Component shall be deemed to be two Components with terms identical to those of such Relevant Component, except that the first such Component (the “Unwound Component”) shall have an Initial Principal Amount equal to the product of the Unwind Percentage and the Initial Principal Amount of such Relevant Component, and the second such Component (the “Surviving Component”) shall have an Initial Principal Amount equal to the product of (x) one minus the Unwind Percentage and (y) the Initial Principal Amount of such Relevant Component. Issuer shall pay the Termination Amount for all Relevant Components (or, in the case of a partial unwind, all Unwound Components) on the Unwind Date. In the case of a partial unwind, each Surviving Component shall survive and continue to be outstanding and in full force and effect hereunder.

          (b)     Except as expressly set forth herein, upon payment and delivery of the Termination Amount for any Component for which an Unwind Date has so been declared, all of Issuer’s obligations in respect of the payment and/or delivery pursuant to Section 4 shall be deemed satisfied with respect to such Component.

          SECTION 17.   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 Net Settlement Amount or any other term of the Notes as it reasonably determines are appropriate to preserve the economic value of the transactions contemplated hereby to the Noteholders due to potential risks under applicable securities laws relating to such Noteholders’ 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 Noteholders, then the Noteholders will have a right to accelerate such a portion of the Notes that would preserve such economic value to such holders (and such an acceleration shall be treated as the designation of an Accelerated Maturity Date).

          SECTION 18.   Indemnification.   Issuer agrees to indemnify and hold harmless Purchaser, its Affiliates and its assignees and their respective directors, officers, employees, agents and controlling persons (Purchaser and each such person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities, joint or several, to which such Indemnified Party may become subject, and relating to or arising out of any third party claims arising out of the transactions contemplated by the Transaction Documents, and will reimburse any Indemnified Party for all expenses (including reasonable counsel fees and expenses) as they are incurred in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Issuer. Issuer will not be liable under the foregoing indemnification provision to the extent that any loss, claim, damage, liability or expense has resulted from Purchaser’s breach of a material term of such Transaction Document, willful misconduct or gross negligence. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Issuer shall contribute, to the maximum extent permitted by law (but only to the extent that such harm was not caused by Purchaser’s breach of a material term of such Transaction Document, willful misconduct or gross negligence), to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability. Issuer also agrees that no Indemnified Party shall have any liability to Issuer or any person asserting claims on behalf of or in right of Issuer in connection with or as a result of any matter referred to in any Transaction Document except to the extent that any losses, claims, damages, liabilities or expenses incurred by Issuer result from the breach of a material term of such Transaction Document, or the Indemnified Party’s gross negligence or willful misconduct. The provisions of this Section 18 shall survive termination or completion of any Transaction Document and any assignment and delegation of any Transaction Document and shall inure to the benefit of any successor or assignee of Purchaser.

          SECTION 19.   Delivery of Collateral.   (a) On each Funding Day, Issuer shall deliver to Purchaser in pledge hereunder Eligible Collateral consisting of a number of shares of NRG Common Stock equal to the product of the Daily Share Percentage and the Daily Notional Number of Shares for the Schedule Trading Day in the Reference Period corresponding to such Funding Day (such shares of NRG Common Stock, the “Initial Pledged Items”). “Eligible Collateral” means Cash, shares of NRG Common Stock and Qualifying Preferred Stock, in each case provided that Issuer has good and marketable title thereto, free of any and all lien, mortgage, interest, pledge, charge or encumbrance of any kind (other than the security interests in the Collateral created hereby, a “Lien”) and Transfer Restrictions and that Purchaser has a valid, first priority perfected security interest therein, a first Lien thereon and Control with respect thereto.

          Any delivery of any securities or security entitlements (each as defined in Section 8-102 of the UCC) as Collateral to Purchaser by Issuer shall be effected (A) in the case of Collateral consisting of certificated securities registered in the name of Issuer, by delivery of certificates representing such securities to the Custodian, accompanied by any required transfer tax stamps, and in suitable form for transfer by delivery or accompanied by duly executed instruments of transfer or assignment in blank, with signatures appropriately guaranteed, all in form and substance satisfactory to Purchaser, and the crediting by the Custodian of such securities to a securities account (as defined in Section 8-501 of the UCC) (the “Collateral Account”) of Purchaser maintained by the Custodian, (B) in the case of Collateral consisting of uncertificated securities registered in the name of Issuer, by transmission by Issuer of an instruction to the issuer of such securities instructing such issuer to register such securities in the name of the Custodian or its nominee, accompanied by any required transfer tax stamps, the issuer’s compliance with such instructions and the crediting by the Custodian of such securities to the Collateral Account, (C) in the case of securities in respect of which security entitlements are held by Issuer through a securities intermediary, by the crediting of such securities, accompanied by any required transfer tax stamps, to a securities account of the Custodian at such securities intermediary or, at the option of Purchaser, at another securities intermediary satisfactory to Purchaser and the crediting by the Custodian of such securities to the Collateral Account or (D) in any case, by complying with such alternative delivery instructions as Purchaser shall provide to Issuer in writing. Any Cash held by Issuer at any time shall be held in the Collateral Account or, if Purchaser has delivered alternative instructions to Issuer in writing, as directed pursuant to such instructions.

          SECTION 20.   Grant Of Security Interests In The Collateral.   In order to secure the full and punctual payment, observance and performance of the covenants and agreements contained in this Agreement and the Notes (such covenants and agreements, collectively, the “Secured Obligations”), Issuer hereby assigns and pledges to Purchaser, and grants to Purchaser, as secured party, for the benefit of the Noteholders from time to time, a security interests in and to, and a Lien upon and right of set-off against, and transfers to Purchaser, as and by way of a security interest having priority over all other security interests, with power of sale, all of Issuer’s right, title and interest in and to all of Issuer’s now existing or hereafter arising rights, title, interests, powers and privileges in and to all of the following assets of Issuer, wherever situated, whether now existing or hereafter acquired (collectively, the “Collateral”): (i) all Accounts; (ii) all Chattel Paper; (iii) all Deposit Accounts; (iv) all Documents; (v) all Equipment; (vi) all Financial Assets; (vii) all General Intangibles; (viii) all Instruments; (ix) all Inventory; (x) all Investment Property; (xi) all Securities Accounts; (xii) all Eligible Collateral of Issuer; (xiii) the Collateral Account; (xiv) all Cash or other money, cash or cash equivalents of Issuer; (xv) all books and records pertaining to the Collateral; and (xvi) all Proceeds of any of
the foregoing.

The parties hereto expressly agree that all rights, assets and property at any time held in or credited to the Collateral Account shall be treated as financial assets (as defined in Section 8-102 of the UCC).

          SECTION 21.   Certain Covenants Of Issuer Relating To The Collateral.   Issuer agrees that, so long as any of the Secured Obligations remain outstanding and other than as contemplated by the Transaction Documents:

          (a)     Issuer shall ensure at all times that a Collateral Event of Default shall not occur, and shall pledge additional Collateral in the manner described hereunder as necessary to cause such requirement to be met. “Collateral Event of Default” means, at any time, the occurrence of either of the following: (A) failure of the Collateral to include, as Eligible Collateral, a number of shares of NRG Common Stock at least equal to the aggregate Number of Underlying Shares for all Notes issued hereunder or an Equivalent Number of Qualifying Preferred Stock or (B) failure at any time of the security interests in the Collateral created hereby to constitute valid and perfected security interests in all of the Collateral, subject to no prior, equal or junior Lien, and, with respect to any Collateral consisting of securities or security entitlements (each as defined in Section 8-102 of the UCC), as to which Purchaser has Control, or, in each case, assertion of such by Issuer in writing.

          (b)     Issuer shall, at its own expense and in such manner and form as Purchaser may require, give, execute, deliver, file and record any financing statement, notice, instrument, document, agreement or other papers that may be necessary or desirable in order to (i) create, preserve, perfect, substantiate or validate any security interest granted pursuant hereto, (ii) create or maintain Control with respect to any such security interests in any investment property (as defined in Section 9-102(a) of the UCC) or (iii) enable Purchaser to exercise and enforce its rights hereunder with respect to such security interest.

          (c)     Issuer shall warrant and defend Issuer’s title to the Collateral, subject to the rights of Purchaser, against the claims and demands of all persons. Purchaser may elect, but without an obligation to do so, to discharge any Lien of any third party on any of the Collateral.

          (d)     Issuer agrees that Issuer shall not change (i) Issuer’s legal name, its identity or limited liability company structure or its Federal Taxpayer Identification Number in any manner or (ii) Issuer’s “location” (as defined in Section 9-307 of UCC), unless (x) Issuer shall have given Purchaser not less than 10 days’ prior notice thereof and (y) all filings have been made under the UCC and all other actions have been taken that are required so that such change will not at any time adversely affect the validity, perfection or priority of the security interests in the Collateral created by this clause (d).

          (e)     Issuer agrees that Issuer shall not (i) create or permit to exist any lien (other than the security interests in the Collateral created hereby) or any Transfer Restriction upon or with respect to the Collateral, (ii) sell or otherwise dispose of, or grant any option with respect to, any of the Collateral or (iii) enter into or consent to any agreement (x) that restricts in any manner the rights of any present or future owner of any Collateral with respect thereto (other than this Agreement) or (y) pursuant to which any person other than Issuer, Purchaser and any securities intermediary through whom any of the Collateral is held (but in the case of any such securities intermediary only in respect of Collateral held through it) has or will have Control in respect of any Collateral.

          SECTION 22.   Administration Of The Collateral And Valuation Of Securities:   (a) Purchaser shall determine on each Business Day whether a Collateral Event of Default shall have occurred. If on any Business Day Purchaser reasonably determines that a Collateral Event of Default shall have occurred, Purchaser shall promptly notify Issuer of such determination by telephone call to Issuer followed by a written confirmation of such call.

          (b)     Concurrently with the delivery of any additional Eligible Collateral to Purchaser pursuant to Section 19 above, Issuer shall notify Purchaser on the date of such delivery of the identity of the additional items of Eligible Collateral being pledged and the representations and warranties contained in Section 6(s) through Section 6(x) above shall be deemed to be repeated as of such date with respect to such items of additional Eligible Collateral.

          (c)     Issuer shall be permitted to substitute as Collateral an Equivalent Number of Qualifying Preferred Stock that meets the criteria for Eligible Collateral for NRG Common Stock if, immediately following such substitution, there would not be a Default. The NRG Common Stock so substituted for shall be deemed released from the security interest granted herein and shall no longer constitute Collateral.

          (d)     Purchaser may at any time or from time to time, in its sole discretion, cause any or all of the Collateral that is registered in the name of Issuer or Issuer’s nominee to be transferred of record into the name of the Custodian, Purchaser or its nominee. Issuer shall promptly give to Purchaser copies of any notices or other communications received by Issuer with respect to Collateral that is registered, or held through a securities intermediary, in the name of Issuer or Issuer’s nominee and Purchaser shall promptly give to Issuer copies of any notices and communications received by Purchaser with respect to Collateral that is registered, or held through a securities intermediary, in the name of Custodian, Purchaser or its nominee.

          (e)     Issuer agrees that Issuer shall forthwith upon demand pay to Purchaser:

          (i)     the amount of any taxes that Purchaser or the Custodian may have been required to pay by reason of the security interests in the Collateral created hereby or to free any of the Collateral from any Lien thereon; and

          (ii)     the amount of any and all costs and expenses, including the fees and disbursements of counsel and of any other experts, that Purchaser or the Custodian may incur in connection with (A) the enforcement of this pledge, including such expenses as are incurred to preserve the value of the Collateral and the validity, perfection, rank and value of the security interests in the Collateral created hereby, (B) the collection, sale or other disposition of any of the Collateral, (C) the exercise by Purchaser of any of the rights conferred upon it hereunder or (D) any Acceleration Event.

          Any such amount not paid on demand shall bear interest (computed on the basis of a year of 360 days and payable for the actual number of days elapsed) at a rate per annum equal to 5% plus the prime rate as published from time to time in The Wall Street Journal, Eastern Edition.

          SECTION 23.   Income And Voting Rights In Collateral.   Purchaser shall have the right to receive and retain as Collateral hereunder all proceeds, including, without limitation, any dividend, extraordinary or otherwise, and interest of the Collateral, and Issuer shall take all such action as Purchaser shall deem necessary or appropriate to give effect to such right.

          Unless an Acceleration Event shall have occurred and be continuing, Issuer shall have the right, from time to time, to vote and to give consents, ratifications and waivers with respect to the Collateral.

          If an Acceleration Event shall have occurred and be continuing, Purchaser shall have the right, to the extent permitted by law, and Issuer shall take all such action as may be necessary or appropriate to give effect to such right, to vote and to give consents, ratifications and waivers, and to take any other action with respect to any or all of the Collateral with the same force and effect as if Purchaser were the absolute and sole owner thereof.

          SECTION 24.   Remedies.   Purchaser may exercise all the rights of a secured party under the UCC (whether or not in effect in the jurisdiction where such rights are exercised).

          Issuer hereby irrevocably appoints Purchaser as Issuer’s true and lawful attorney (which power of attorney is coupled with an interest), with full power of substitution, in the name of Issuer, Purchaser or otherwise, for the sole use and benefit of Purchaser, but at the expense of Issuer, to the extent permitted by law, to exercise, at any time and from time to time while an Event of Default has occurred, all or any of the following powers with respect to all or any of the Collateral:

          (a)     to demand, sue for, collect, receive and give acquittance for any and all monies due or to become due upon or by virtue thereof;

          (b)     to settle, compromise, compound, prosecute or defend any action or proceeding with respect thereto;

          (c)     to sell, transfer, assign or otherwise deal in or with the same or the proceeds or avails thereof, as fully and effectually as if Purchaser were the absolute owner thereof and in connection therewith, to make all necessary deeds, bills of sale, instruments of assignment, transfer or conveyance of the property, and all instructions and entitlement orders in respect of the property thus to be (or that is being or has been) sold, transferred, assigned or otherwise dealt in; and

          (d)     to extend the time of payment of any or all thereof and to make any allowance and other adjustments with reference thereto;

provided that Purchaser shall give Issuer not less than one Business Day’s prior written notice of the time and place of any sale or other intended disposition of any of the Collateral, except any Collateral that threatens to decline speedily in value, including, without limitation, equity securities, or is of a type customarily sold on a recognized market. Purchaser and Issuer agree that such notice constitutes “reasonable authenticated notification” within the meaning of Section 9 611(b) of the UCC.

          SECTION 25.   Collateral Rights Termination.   The rights hereby granted by Issuer in the Collateral shall cease, terminate and be void upon satisfaction of all of the Secured Obligations. Any Collateral remaining at the time of such termination shall be fully released and discharged from the security interests in the Collateral created hereby and delivered to Issuer, all at the request and expense of Issuer.

          SECTION 26.   Limit on Beneficial Ownership.   Notwithstanding anything to the contrary in this Agreement, on any Maturity Date, any Accelerated Maturity Date or Unwind Date, upon the occurrence of an Event of Default, or otherwise, in no event shall any Noteholder be entitled to acquire, receive or exercise any rights of a secured party in respect of Collateral consisting of, shares of any class of voting securities of an issuer to the extent that, upon such acquisition, receipt or exercise, the “beneficial ownership” (within the meaning of Section 13 of the Exchange Act of 1934, as amended, and the rules promulgated thereunder) of such Noteholder or any entity that directly or indirectly controls such Noteholder (collectively, such Noteholder’s “Noteholder Group”) would equal or exceed 4.5% of the outstanding shares of such class or any member of the Noteholder Group would be deemed to directly or indirectly own 4.5% or more of the outstanding equity of the issuer of such stock or have the right to vote securities conferring 4.5% or more of the total vote on general corporate matters with respect to such issuer. The inability of any Noteholder to acquire, receive or exercise rights with respect to Collateral consisting of, shares provided by this Agreement at any time as a result of this provision shall not preclude such Noteholder from taking such action at a later time when permitted by this provision. If any delivery owed to any Noteholder hereunder is not made, in whole or in part, as a result of this Section 26, Issuer’s obligation to make such delivery shall not be extinguished, and Issuer shall make such delivery as promptly as practicable following notice from such Noteholder that such delivery would be permitted by this Section 26.

          SECTION 27.   Note Register.   (a) Issuer shall cause to be kept a note register (the “Note Register”) for the Notes in which, subject to such reasonable regulations as it may prescribe, Issuer shall provide for the registration of the Notes and the registration of transfers of the Notes. Issuer shall initially be the note registrar (in such capacity, the “Note Registrar”) for the purpose of registering the Notes and transfers of Notes as herein provided and may appoint a successor to itself, subject to the last sentence of this Section 27(a). Upon any resignation of any Note Registrar, Issuer shall promptly appoint a successor or, if it elects not to make such an appointment, assume the duties of the Note Registrar. If a person other than Issuer is appointed as Note Registrar, Issuer will give Purchaser prompt written notice of the appointment of such Note Registrar and of the location, and any change in the location of the Note Register.

          (b)     Upon surrender for registration of transfer of any certificate representing any Note at an office or agency of Issuer where the principal of the Notes is payable, Issuer shall execute, and the relevant Noteholder shall obtain from Issuer, in the name of the designated transferee or transferees, one or more new certificates of a like aggregate principal amount.

          (c)     At the option of a Noteholder, certificates with respect to any Notes may be exchanged for other certificates of a like aggregate principal amount upon surrender of the certificates to be exchanged at the office or agency of Issuer where the principal of the Notes
are payable.

          (d)     All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of Issuer, evidencing the same debt, and entitled to the same benefits under this Agreement, as the Notes surrendered upon such registration of transfer or exchange.

          (e)     No service charge shall be made by Issuer for any registration of transfer or exchange of any Note, but Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes.

          (f)     Subject to Section 9, the Notes shall be freely transferable at any time without the consent of Issuer to any Person that (i) makes the representations and warranties set forth in Sections 7(f), (g) and (h) as of the date of the relevant transfer, (ii) agrees to the be bound by the covenants set forth in Section 9 and (iii) becomes the Noteholder of Notes with an aggregate Initial Principal Amount of 10% or more of the aggregate Initial Principal Amount of all Notes outstanding at the time of such transfer; provided that the Notes shall not be transferable prior to the payment by Purchaser of the Daily Funding Amount for the Funding Date corresponding to the last Exchange Business Day in the Reference Period.

          SECTION 28.   Mutilated, Destroyed, Lost or Stolen Notes.   (a) If (i) any mutilated Note is surrendered to Issuer, or Issuer receives evidence to its satisfaction of the destruction, loss or theft of any Note, and (ii) there is delivered to Issuer such security or indemnity as may be reasonably required by it to hold Issuer harmless, then, in the absence of notice to Issuer or the Note Registrar that such Note has been acquired by a bona fide purchaser, Issuer shall execute and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Note, a replacement Note of a like aggregate principal amount; provided, however, that if Notes represented by any such destroyed, lost or stolen certificate, but not a mutilated certificate, shall have become or within seven days shall be due and payable, instead of issuing a replacement certificate, Issuer may pay to the holder of such destroyed, lost or stolen Note the amount due when so due or payable without
surrender thereof.

          (b)     Any duplicate Note issued pursuant to this Section 28 in replacement for any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of Issuer, whether or not the mutilated, destroyed, lost or stolen Note shall be found at any time or be enforced by any person, and shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Notes duly issued hereunder.

          SECTION 29 .   Successors and Assigns.   This Agreement and any Note issued hereunder shall inure to the benefit of, and be binding upon, Issuer and Purchaser and their respective successors and assigns (including without limitation any Noteholder).

Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.

          SECTION 32.   Governing Law; Jurisdiction.   (a) THIS AGREEMENT AND THE PRICING CONFIRMATION HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PROVISIONS THEREOF PROVIDED THAT AS TO ANY ITEMS OF COLLATERAL LOCATED IN ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK, PURCHASER SHALL HAVE, IN ADDITION TO ANY RIGHTS UNDER THE LAWS OF THE STATE OF NEW YORK, ALL OF THE RIGHTS TO WHICH A SECURED PARTY IS ENTITLED UNDER THE LAWS OF SUCH OTHER JURISDICTION. THE PARTIES HERETO HEREBY AGREE THAT THE CUSTODIAN’S JURISDICTION, WITHIN THE MEANING OF SECTION 8-110(e) OF THE UCC, INSOFAR AS IT ACTS AS A SECURITIES INTERMEDIARY HEREUNDER OR IN RESPECT HEREOF, IS THE STATE OF NEW YORK.

Each party hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that Purchaser may otherwise have to bring any action or proceeding relating to this Agreement against Issuer or its properties in the courts of any jurisdiction.

          (c)     Issuer irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in Section 32(b). Each party hereto irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of any such suit, action or proceeding in any such court.

          SECTION 33.   Calculation Agent.   All calculations and determinations hereunder shall be made by the Calculation Agent. The Calculation Agent shall make all calculations and determinations hereunder in good faith and in a commercially reasonable manner. All calculations and determinations of the Calculation Agent so made shall be binding on the parties in the absence of manifest error.

          SECTION 34.   Integration; Amendments and Waivers.   (a) Except as provided herein, this Agreement and the Notes constitute the complete agreement between the parties with respect to the subject matter hereof and thereof, supersede any previous agreement or understanding between them relating hereto or thereto and may not be modified, altered or amended except as provided therein.

          (b)     No amendment or waiver of any provision of this Agreement or any Note, nor consent to any departure by Issuer therefrom, shall in any event be effective unless the same shall be in writing and signed by Issuer and Purchaser.

          SECTION 35.   No Waiver by Purchaser.   Purchaser’s failure, at any time or times, to require strict performance by Issuer of any provision of this Agreement or any Note shall not waive, affect or diminish any right of Purchaser thereafter to demand strict compliance and performance herewith or therewith.

None of the undertakings, agreements, warranties, covenants and representations of Issuer contained in this Agreement or any Note and no Event of Default under this Agreement shall be deemed to have been suspended or waived by Purchaser unless such suspension or waiver is by an instrument in writing signed by an officer of Purchaser and directed to Issuer specifying such suspension or waiver.

          SECTION 36.   Waiver of Jury Trial.   The parties hereto waive all right to trial by jury in any action or proceeding to enforce or defend any rights under this Agreement or the Notes.

          SECTION 38.   Severability.   Wherever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

          (c)     Purchaser shall make its own determination as to whether, when or in what manner any hedging or market activities in NRG Common Stock shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the VWAP Price.

          (d)     Any market activities of Purchaser and its Affiliates with respect to NRG Common Stock may affect the market price and volatility of NRG Common Stock, as well as the VWAP Price, each in a manner that may be adverse to Issuer.
