Reg. §1.704-l(b)(2)(ii)(d)(5), or Treas. Reg. §1.704- l(b)(2)(ii)(d)(6), items of Company income and gain shall be specially allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by the Regulations, the Adjusted Capital Account Deficit of the Member as quickly as possible, provided that an allocation pursuant to this Section 5.3 (c) shall be made only if and to the extent that the Member would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article V have been tentatively made as if this Section 5.3(c) were not in the Agreement.

(e) Nonrecourse Deductions. Nonrecourse Deductions for any Allocation Year shall be specially allocated to the Members in proportion to their respective Common Interest percentages.

(f) Member Nonrecourse Deductions. Any Member Nonrecourse Deductions for any Allocation Year shall be specially allocated to the Member who bears the economic risk of loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Treas.

(g) Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Company asset, pursuant to Sections 734(b) or 743(b) of the Code is required, pursuant to Treas. Reg. §1.704-l(b)(2)(iv)(m)(2) or Treas. Reg. §1.704- l(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts as the result of a distribution to a Member in complete liquidation of such Member’s interest in the Company, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Members in accordance with their interests in the Company in the event Treas. Reg. §1.704-

l(b)(2)(iv)(m)(2) applies, or to the Member to whom such distribution was made in the event Treas. Reg. §1.704-l(b)(2)(iv)(m)(4) applies.

(h) Allocations Relating to Taxable Issuance of Common Interests. Any income, gain, loss, or deduction realized as a direct or indirect result of the issuance of Common Interests by the Company to a Member (the “Issuance Items”) shall be allocated among the Members so that, to the extent possible, the net amount of such Issuance Items, together with all other allocations under this Agreement to each Member shall be equal to the net amount that would have been allocated to each such Member if the Issuance Items had not been realized.

5.4 Curative Allocations. The allocations set forth in Sections 5.3(a), 5.3(b), 5.3(c), 5.3(d), 5.3(e), 5.3(f), 5.3(g), and 5.5 (the “Regulatory Allocations”) are intended to comply with certain requirements of the Regulations. It is the intent of the Members that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Company income, gain, loss, or deduction pursuant to this Section 5.4. Therefore, notwithstanding any other provision of this Article V (other than the Regulatory Allocations), the Board shall make such offsetting special allocations of Company income, gain, loss, or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if the Regulatory Allocations were not part of the Agreement and all Company items were allocated pursuant to Sections 5.1, 5.2, and 5.3(h).

5.5 Loss Limitation. Losses allocated pursuant to Section 5.2 hereof shall not exceed the maximum amount of Losses that can be allocated without causing any Member to have an Adjusted Capital Account Deficit at the end of any Allocation Year. In the event some but not all of the Members would have Adjusted Capital Account Deficits as a consequence of an allocation of Losses pursuant to Section 5.2 hereof, the limitation set forth in this Section 5.5 shall be applied on a Member by Member basis and Losses not allocable to any Member as a result of such limitation shall be allocated to the other Members in accordance with the positive balances in such Member’s Capital Accounts so as to allocate the maximum permissible Losses to each Member under Treas. Reg. §1.704-l(b)(2)(ii)(d).

5.6 Other Allocation Rules.

(a) For purposes of determining the Profits, Losses, or any other items allocable to any period, Profits, Losses, and any such other items shall be determined on a daily, monthly, or other basis, as determined by the Board using any permissible method under Section 706 of the Code and the Regulations thereunder.

(b) The Members are aware of the income tax consequences of the allocations made by this Article V and hereby agree to be bound by the provisions of this Article V in reporting their shares of Company income and loss for income tax purposes.

(c) Solely for purposes of determining a Member’s proportionate share of the “excess nonrecourse liabilities” of the Company within the meaning of Treas. Reg. §1.752-3(a)(3), the Members’ interests in Company profits are in proportion to their respective Common Interest percentages.

To the extent permitted by Treas. Reg. §1.704-2(h)(3), the Board shall endeavor to treat distributions of Net Cash Flow as having been made from the proceeds of a Nonrecourse Liability or a Member Nonrecourse Debt only to the extent that such distributions would cause or increase an Adjusted Capital Account Deficit for any Member.

5.7 Tax Allocations: Section 704(c) of the Code. In accordance with Section 704(c) of the Code and the Regulations thereunder, income, gain, loss, and deduction with respect to any Property contributed to the capital of the Company shall, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such Property to the Company for federal income tax purposes and its initial Gross Asset Value (computed in accordance with the definition of Gross Asset Value) using the “traditional method” as described in Treas. Reg. §1.704-3(b)(l).

In the event the Gross Asset Value of any Company asset is adjusted pursuant to subparagraph (ii) of the definition of Gross Asset Value, subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Section 704(c) of the Code and the Regulations thereunder.

Any elections or other decisions relating to such allocations shall be made by the Board in any manner that reasonably reflects the purpose and intention of this Agreement. Allocations pursuant to this Section 5.7 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement.

(b) A Member may not receive a distribution from the Company to the extent that, after giving effect to the distribution, all liabilities of the Company, other than liabilities to Members on account of their Capital Contributions, would exceed the fair value of the Company’s assets.

(c) To the extent a Member receives a distribution of Company property which is Section 751 Property, Other Property, or both, the Company may make a true-up distribution and/or take other appropriate actions (including increasing the amount of any distribution or making special allocations to one ore more of its Members), in consultation with it tax adviser, so that Section 751(b) of the Code will not apply to the distribution.

ARTICLE VII
DISSOLUTION

7.1 Events of Dissolution. The Company shall be dissolved and its affairs wound up upon the occurrence of any of the following events (each, an “Event of Dissolution”):

(a) The Members holding a majority of the Common Interests vote for dissolution;

(b) The Board votes for dissolution;

(d) At any time at which there shall be no Members.

7.2 Liquidation and Termination. On dissolution of the Company, the Board may appoint one or more other Persons as liquidator (the “Liquidator”). The Liquidator shall proceed diligently to wind up the affairs of the Company and make final distributions as provided in this Agreement. The costs of liquidation shall be borne as a Company expense. Until final distribution, the Liquidator shall continue to operate the Company properties with all of the power and authority of the Board. The steps to be accomplished by the Liquidator are as follows:

(a) as promptly as practicable after dissolution and again after final liquidation, the Liquidator shall cause a proper accounting to be made by a recognized firm of certified public accountants of the Company’s assets, liabilities, and operations through the last day of the calendar month in which the dissolution occurs or the final liquidation is completed, as applicable;

(b) the Liquidator shall pay from Company funds all of the debts and liabilities of the Company (including, without limitation, all expenses incurred in liquidation) or otherwise make adequate provision for them (including, without limitation, the establishment of a cash escrow fund for contingent liabilities in such amount and for such term as the Liquidator may reasonably determine); and

(i) the Liquidator may sell any or all Company property, including to Members, and any resulting gain or loss from each sale shall be computed and allocated to the Capital Accounts of the Members;

(ii) with respect to all Company property that has not been sold, the fair market value of that property shall be determined and the Capital Accounts of the Members shall be adjusted to reflect the manner in which the unrealized income, gain, loss, and deduction inherent in property that has not been reflected in the Capital Accounts previously would be allocated among the Members if there were a taxable disposition of that property for the fair market value of that property on the date of distribution; and

(iii) Company property shall be distributed among the Members in accordance with the positive Capital Account balances of the Members, as determined after taking into account all Capital Account adjustments for the taxable year of the Company during which the liquidation of the Company occurs (other than those made by reason of this clause (iii)); and those distributions shall be made by the end of the taxable year of the Company during which the liquidation of the Company occurs (or, if later, 90 days after the date of the liquidation).

All distributions in kind to the Members shall be made subject to the liability of each distributee for its allocable share of costs, expenses, and liabilities previously incurred or for which the Company has committed prior to the date of termination and those costs, expenses, and liabilities shall be allocated to the distributee under this Section 8.2. The distribution of cash and/or property to a Member in accordance with the provisions of this Section 8.2 constitutes a complete return to the Member of its Capital Contributions and a complete distribution to the Member of its Common Interests and all the Company’s property. To the extent that a Member returns funds to the Company, it has no claim against any other Member for those funds.

7.3 Compliance with Regulations; Deficit Capital Accounts. In the event the Company is “liquidated” within the meaning of Treas. Reg. §1.704-l(b)(2)(ii)(g), distributions shall be made pursuant to this Article VIII to the Members who have positive Capital Accounts in compliance with Treas. Reg. §1.704-l(b)(2)(ii)(b)(2). If any Member has a deficit balance in his Capital Account (after giving effect to all contributions, distributions and allocations for all Allocation Years, including the Allocation Year during which such liquidation occurs), such Member shall have no obligation to make any contribution to the capital of the Company with respect to such deficit, and such deficit shall not be considered a debt owed to the Company or to any other Person for any purpose whatsoever. In the discretion of the Liquidator, a pro rata portion of the distributions that would otherwise be made to the Members pursuant to this Article VIII may be:

(a) Distributed to a trust established for the benefit of the Members for the purposes of liquidating Company assets, collecting amounts owed to the Company, and paying any contingent or unforeseen liabilities or obligations of the Company. The assets of any such trust shall be distributed to the Members from time to time, in the reasonable discretion of the Liquidator, in the same proportions as the amount distributed to such trust by the Company would otherwise have been distributed to the Members pursuant to Section 8.2 hereof; or

(b) Withheld to provide a reasonable reserve for Company liabilities (contingent or otherwise) and to reflect the unrealized portion of any installment obligations owed to the Company, provided that such withheld amounts shall be distributed to the Members as soon as practicable.

ARTICLE VIII
TRANSFER OF INTERESTS IN THE COMPANY

Each of the Members may sell, assign, transfer, convey, gift, exchange or otherwise dispose of any or all of its Common Interests and, upon receipt by the Company of a written agreement executed by the person or entity to whom such Common Interests are to be transferred agreeing to be bound by the terms of this Agreement, such person shall be admitted as a member.

ARTICLE IX
TAX MATTERS

9.1 Tax Elections. The Board shall, without any further consent of the Members being required (except as specifically required herein), make any and all elections for federal, state, local, and foreign tax purposes including, without limitation, any election, if permitted by applicable law: (i) to make the election provided for in Section 6231(a)(l)(B)(ii) of the Code; (ii) to adjust the basis of Property pursuant to Sections 754, 734(b) and 743(b) of the Code, or comparable provisions of state, local or foreign law, in connection with transfers of Common Interests and Company distributions; (iii) with the consent of all of the Members, to extend the statute of limitations for assessment of tax deficiencies against the Members with respect to adjustments to the Company’s federal, state, local or foreign tax returns; and (iv) to the extent provided in Section 6221 through 6231 of the Code and similar provisions of federal, state, local or foreign law, to represent the Company and the Members before taxing authorities or courts of competent jurisdiction in tax matters affecting the Company or the Members in their capacity as Members, and to file any tax returns and execute any agreements or other documents relating to or affecting such tax matters, including agreements or other documents that bind the Members with respect to such tax matters or otherwise affect the rights of the Company and the Members. NRG Energy, Inc. is specifically authorized to act as the “Tax Matters Member” under the Code and in any similar capacity under state or local law.

ARTICLE X
EXCULPATION AND INDEMNIFICATION

10.1 Exculpation. Notwithstanding any other provisions of this Agreement, whether express or implied, or any obligation or duty at law or in equity, none of the Members, Managers, or any officers, directors, stockholders, partners, employees, affiliates, representatives or agents of any of the foregoing, nor any officer, employee, representative or agent of the Company (individually, a “Covered Person” and, collectively, the “Covered Persons”) shall be liable to the Company or any other person bound by this Agreement for any act or omission (in relation to the Company, its property or the conduct of its business or affairs, this Agreement, any related document or any transaction or investment contemplated hereby or thereby) taken or omitted by a Covered

Person in the reasonable belief that such act or omission is in or is not contrary to the best interests of the Company and is within the scope of authority granted to such Covered Person by the Agreement, provided such act or omission does not constitute fraud, willful misconduct, bad faith, or gross negligence.

10.2 Indemnification. To the fullest extent permitted by law, the Company shall indemnify and hold harmless each Covered Person from and against any and all losses, claims, demands, liabilities, expenses, judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative (“Claims”), in which the Covered Person may be involved, or threatened to be involved, as a party or otherwise, by reason of its management of the affairs of the Company or which relates to or arises out of the Company or its property, business or affairs. A Covered Person shall not be entitled to indemnification under this Section 11.2 with respect to (i) any Claim with respect to which such Covered Person has engaged in fraud, willful misconduct, bad faith or gross negligence or (ii) any Claim initiated by such Covered Person unless such Claim (or part thereof) (A) was brought to enforce such Covered Person’s rights to indemnification hereunder or (B) was authorized or consented to by the Board. Expenses incurred by a Covered Person in defending any Claim shall be paid by the Company in advance of the final disposition of such Claim upon receipt by the Company of an undertaking by or on behalf of such Covered Person to repay such amount if it shall be ultimately determined that such Covered Person is not entitled to be indemnified by the Company as authorized by this Section 11.2.

10.3 Amendments. Any repeal or modification of this Article 11 by the Members shall not adversely affect any rights of such Covered Person pursuant to this Article 8, including the right to indemnification and to the advancement of expenses of a Covered Person existing at the time of such repeal or modification with respect to any acts or omissions occurring prior to such repeal or modification.

ARTICLE XI
MISCELLANEOUS

11.1 Amendments. Amendments to this Agreement and to the Certificate of Formation shall be approved in writing by the Members owning a majority of the Common Interests. An amendment shall become effective as of the date specified in the approval of the Members or if none is specified as of the date of such approval or as otherwise provided in the Act.

11.2 Severability. If any provision of this Agreement is held to be invalid or unenforceable for any reason, such provision shall be ineffective to the extent of such invalidity or unenforceability; provided, however, that the remaining provisions will continue in full force without being impaired or invalidated in any way unless such invalid or unenforceable provision or clause shall be so significant as to materially affect the expectations of the Members regarding this Agreement. Otherwise, any invalid or unenforceable provision shall be replaced by the Members with a valid provision which

most closely approximates the intent and economic effect of the invalid or unenforceable provision.

11.3 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without regard to the principles of conflicts of laws thereof.

11.4 Limited Liability Company. The Members intend to form a limited liability company and do not intend to form a partnership under the laws of the State of Delaware or any other laws.
