          WHEREAS, Issuer and Purchaser wish to sell and purchase Issuer’s Series 1 Exchangeable Limited
Liability Company Preferred Interests (the “Preferred Interests”) on the terms and conditions as
set forth herein; and

          WHEREAS, the Preferred Interests will have the terms and provisions contained in the
Certificate of Designations to be filed with the Delaware Secretary of State as of the date hereof
(the “Certificate of Designations”); and

          WHEREAS, the Preferred Interests will be redeemable and exchangeable into cash and shares of

          WHEREAS, the Preferred Interests will be offered and sold to Purchaser without registration
under the Securities Act of 1933, as amended (the “Act”), in reliance on an exemption pursuant to
Section 4(2) under the Act;

          NOW, THEREFORE, in consideration of their mutual covenants herein contained, the parties
hereto, intending to be legally bound, hereby mutually covenant and agree as follows:

          1.   Definitions.   As used herein, the following terms have the meanings set forth below.
Capitalized terms not defined herein shall have the meaning ascribed to them in the Certificate of
Designations or, if the meaning of any such term is not specified in the Certificate of
Designations, the meaning ascribed to such term in the Note Purchase Agreement.

          “Daily Funding Amount” means, for the Preferred Interests initially issued on the Issue Date
pursuant to Section 3, for any Funding Date, the product of (i) the Daily Notional Amount for the
Scheduled Trading Day in the Reference Period corresponding to such Funding Date and (ii) the
Funding Percentage. Each Daily Funding Amount shall be allocated among all of the Preferred
Interests proportionally for the purpose of determining the Initial Base Liquidation Preferences of
each such Preferred Interest.

 

 

          “Daily Share Percentage” means 55.0000%.

Issuer, Credit Suisse International and Credit Suisse Securities (USA) LLC, as agent.

“Potential Early Redemption Event” means any event that, with the passage of time or giving of
notice or both, will constitute an Early Redemption Event.

          2.   Single Agreement.   All Preferred Interests are issued and sold by Issuer and purchased by
Purchaser pursuant to this Agreement in reliance on the fact that this Agreement, the Pricing
Confirmation and all Preferred Interests issued hereunder form a single agreement between the
parties, and the parties would not otherwise issue and sell or purchase any Preferred Interests.

          3.   Sale and Purchase.   (a) Upon the terms and subject to the conditions set forth herein, Issuer
agrees to issue and sell to Purchaser, and Purchaser agrees to purchase from Issuer, Preferred
Interests having the terms set forth in the Certificate of Designations and in the Pricing
Confirmation.

                    (b)     On the Issue Date, Issuer will deliver a certificate substantially in
the form of Exhibit A hereto, duly completed, representing the Preferred Interests issued on the
Issue Date to Purchaser (or an agent specified by Purchaser).

                    (c)     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.

                    (d)     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
Preferred Interests 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.

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.

          12.   Governing Law.

                    (a)     THIS AGREEMENT AND ANY PRICING CONFIRMATIONS 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.

                    (b)     The parties hereto irrevocably and unconditionally submit, for themselves and
their property, to the nonexclusive jurisdiction of the Federal and state courts located in the
Borough of Manhattan, in the City of New York in any suit or proceedings arising out of or relating
to this Agreement, the transactions contemplated hereby, or for the recognition or enforcement of
any judgment. 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 clause (b) of this section. 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.

          13.   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.

          14.   Matters Relating to Credit Suisse Capital LLC and Credit Suisse Securities (USA) LLC.

                    (a)     Agent may assign or transfer any of its rights or duties hereunder without the
prior written consent of the other parties hereto to any affiliate of Credit Suisse, so long as
such affiliate is a broker-dealer registered with the Securities and Exchange Commission.

14

 

                    (b)     Agent shall act as “agent” for Purchaser and Issuer in connection with the
transaction contemplated by this Agreement.

                    (c)     Agent will furnish to Purchaser upon written request a statement as to the
source and amount of any remuneration received or to be received by Agent in connection herewith.

                    (d)     Agent has no obligation hereunder, by guaranty, endorsement or otherwise, with
respect to performance of Purchaser’s obligations hereunder or under the any Transaction Document.

                    (e)     Purchaser is an “OTC derivatives dealer” as such term is defined in the Exchange
Act and is an affiliate of Agent.

                    (f)     Purchaser is not a member of the Securities Investor Protection Corporation.

          15.   Integration; Amendments and Waivers.

                    (a)     Except as provided herein, this Agreement and the Pricing Confirmation
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, 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.

          16.   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 the Certificate of Designations shall
not waive, affect or diminish any right of Purchaser thereafter to demand strict compliance and
performance herewith or therewith. Any suspension or waiver by Purchaser of an Early Redemption
Event under the Certificate of Designations shall not suspend, waive or affect any other default or
Early Redemption Event by Issuer under the Certificate of Designations whether the same is prior or
subsequent thereto and whether of the same or of a different type. None of the undertakings,
agreements, warranties, covenants and representations of Issuer contained in this Agreement and no
Early Redemption Event under the Certificate of Designations 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.

15

 

          17.   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 Certificate of
Designations.

          18.   Non-Confidentiality.   The parties hereby agree that (i) Issuer and each of its employees,
representatives, or other agents may disclose to any persons the tax treatment and tax structure of
the transactions contemplated by the Transaction Documents and all materials of any kind, including
opinions or other tax analyses, provided by Purchaser and its affiliates to Issuer relating to such
tax treatment and tax structure; provided that the foregoing does not constitute an authorization
to disclose the identity of Purchaser or its affiliates, agents or advisers, or, except to the
extent relating to such tax structure or tax treatment, any specific pricing terms or commercial or
financial information, and (ii) Purchaser does not assert any claim of proprietary ownership in
respect of any description contained herein or therein relating to the use of any entities, plans
or arrangements to give rise to a particular United States federal income tax treatment for Issuer.

          19.   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.

          20.   Agreements Regarding the Pricing Confirmation.

                    (a)     This Agreement, as supplemented by the Pricing Confirmation, is a “qualified
financial contract”, as such term is defined in Section 5-701(b)(2) of the General Obligations Law
of New York (the “General Obligations Law”); (iii) the Pricing Confirmation constitutes a
“confirmation in writing sufficient to indicate that a contract has been made between the parties”
hereto, as set forth in Section 5-701(b)(3)(b) of the General Obligations Law; and (iv) this
Agreement constitutes a prior “written contract” as set forth in Section 5-701(b)(1)(b) of the
General Obligations Law, and each party hereto intends and agrees to be bound by this Agreement, as
supplemented by the

Pricing Confirmation.

                    (b)     Issuer and Purchaser further agree and acknowledge that this Agreement, as
supplemented by the Pricing Confirmation, constitutes a contract “for the sale or purchase of a
security”, as set forth in Section 8-113 of the Uniform Commercial Code of New York.

          21.   Purchaser’s Market Activities.

16

 

                    (a)     At any time Purchaser remains a Holder of Preferred Interests, Purchaser and its
affiliates may buy or sell shares of NRG Common Stock or other securities or buy or sell options or
futures contracts or enter into swaps or other derivative securities in order to adjust its hedge
position with respect to the Preferred Interests held by Purchaser.

                    (b)     Purchaser and its affiliates also may be active in the market for shares of NRG
Common Stock other than in connection with hedging activities in relation to the Preferred
Interests held by Purchaser.

                    (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 Closing Price
and/or 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 Closing Price
and/or the VWAP Price, each in a manner that may be adverse to Issuer.

          22.   Survival.   The representations and warranties of Issuer and Purchaser in this Agreement
shall survive the execution, delivery and acceptance hereof by the parties hereto and the closing
of the transactions described herein or related hereto.

          2.     Single Agreement.  All Preferred Interests are issued and sold by Issuer and
purchased by Purchaser pursuant to this Agreement in reliance on the fact that this Agreement, the
Pricing Confirmation and all Preferred Interests issued hereunder form a single agreement between
the parties, and the parties would not otherwise issue and sell or purchase any Preferred
Interests.

          3.     Sale
and Purchase.  (a) Upon the terms and subject to the conditions set forth herein, Issuer
agrees to issue and sell to Purchaser, and Purchaser agrees to purchase from Issuer, Preferred
Interests having the terms set forth in the Certificate of Designations and in the Pricing
Confirmation.

               (b)     On the Issue Date, Issuer will deliver a certificate substantially
in the form of Exhibit A hereto, duly completed, representing the Preferred Interests issued on the
Issue Date to Purchaser (or an agent specified by Purchaser).

               (c)     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.

               (d)     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 Preferred Interests 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.

          9.     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 transaction 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 9 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.

          11.     Counterparts.  This Agreement may be signed in counterparts, each of which shall be
an original and all of which together shall constitute one and the same instrument.

          12.     Governing Law.

               (a)     THIS AGREEMENT AND ANY PRICING CONFIRMATIONS 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.

               (b)     The parties hereto irrevocably and unconditionally submit, for themselves
and their property, to the nonexclusive jurisdiction of the Federal and state courts located in the
Borough of Manhattan, in the City of New York in any suit or proceedings arising out of or relating
to this Agreement, the transactions contemplated hereby, or for the recognition or enforcement of
any judgment. 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 clause (b) of this section. 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.

          13.     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.

          14.     Matters Relating to Credit Suisse Capital LLC and Credit Suisse Securities (USA)
LLC.

               (a)     Agent may assign or transfer any of its rights or duties hereunder without
the prior written consent of the other parties hereto to any affiliate of Credit Suisse, so long as
such affiliate is a broker-dealer registered with the Securities and Exchange Commission.

14

 

               (b)     Agent shall act as “agent” for Purchaser and Issuer in connection with the
transaction contemplated by this Agreement.

               (c)     Agent will furnish to Purchaser upon written request a statement as to the
source and amount of any remuneration received or to be received by Agent in connection herewith.

               (d)     Agent has no obligation hereunder, by guaranty, endorsement or otherwise,
with respect to performance of Purchaser’s obligations hereunder or under the any Transaction
Document.

               (e)     Purchaser is an “OTC derivatives dealer” as such term is defined in the
Exchange Act and is an affiliate of Agent.

               (f)     Purchaser is not a member of the Securities Investor Protection
Corporation.

          15.     Integration; Amendments and Waivers.

               (a)     Except as provided herein, this Agreement and the Pricing Confirmation
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, 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.

          16.     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 the Certificate of Designations
shall not waive, affect or diminish any right of Purchaser thereafter to demand strict compliance
and performance herewith or therewith. Any suspension or waiver by Purchaser of an Early
Redemption Event under the Certificate of Designations shall not suspend, waive or affect any other
default or Early Redemption Event by Issuer under the Certificate of Designations whether the same
is prior or subsequent thereto and whether of the same or of a different type. None of the
undertakings, agreements, warranties, covenants and representations of Issuer contained in this
Agreement and no Early Redemption Event under the Certificate of Designations 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.

15

 

          17.     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 Certificate of
Designations.

          18.     Non-Confidentiality.  The parties hereby agree that (i) Issuer and each of its
employees, representatives, or other agents may disclose to any persons the tax treatment and tax
structure of the transactions contemplated by the Transaction Documents and all materials of any
kind, including opinions or other tax analyses, provided by Purchaser and its affiliates to Issuer
relating to such tax treatment and tax structure; provided that the foregoing does not constitute
an authorization to disclose the identity of Purchaser or its affiliates, agents or advisers, or,
except to the extent relating to such tax structure or tax treatment, any specific pricing terms or
commercial or financial information, and (ii) Purchaser does not assert any claim of proprietary
ownership in respect of any description contained herein or therein relating to the use of any
entities, plans or arrangements to give rise to a particular United States federal income tax
treatment for Issuer.

          19.     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.

          20.     Agreements Regarding the Pricing Confirmation.

               (a)     This Agreement, as supplemented by the Pricing Confirmation, is a
“qualified financial contract”, as such term is defined in Section 5-701(b)(2) of the General
Obligations Law of New York (the “General Obligations Law”); (iii) the Pricing Confirmation
constitutes a “confirmation in writing sufficient to indicate that a contract has been made between
the parties” hereto, as set forth in Section 5-701(b)(3)(b) of the General Obligations Law; and
(iv) this Agreement constitutes a prior “written contract” as set forth in Section 5-701(b)(1)(b)
of the General Obligations Law, and each party hereto intends and agrees to be bound by this
Agreement, as supplemented by the Pricing Confirmation.

               (b)     Issuer and Purchaser further agree and acknowledge that this Agreement, as
supplemented by the Pricing Confirmation, constitutes a contract “for the sale or purchase of a
security”, as set forth in Section 8-113 of the Uniform Commercial Code of New York.

          21.     Purchaser’s Market Activities.

16

 

               (a)     At any time Purchaser remains a Holder of Preferred Interests, Purchaser
and its affiliates may buy or sell shares of NRG Common Stock or other securities or buy or sell
options or futures contracts or enter into swaps or other derivative securities in order to adjust
its hedge position with respect to the Preferred Interests held by Purchaser.

               (b)     Purchaser and its affiliates also may be active in the market for shares
of NRG Common Stock other than in connection with hedging activities in relation to the Preferred
Interests held by Purchaser.

               (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 Closing
Price and/or 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 Closing
Price and/or the VWAP Price, each in a manner that may be adverse to Issuer.

          22.     Survival.  The representations and warranties of Issuer and Purchaser in this
Agreement shall survive the execution, delivery and acceptance hereof by the parties hereto and the
closing of the transactions described herein or related hereto.
