ARTICLE VII

ALLOCATIONS

        Section 7.1    Profits and Losses.

        (a)    Profits.    Subject to Section 7.1(c), any Profits of the Company for any Fiscal Year or any other period shall be allocated among the Members as follows:

        (1)   first, to the Members pro rata until the cumulative amount of Profits allocated to each Member pursuant to this Section 7.1(a)(1) equals the cumulative amount of Losses allocated to each Member pursuant to Section 7.1(b), with such Losses to be offset in reverse chronological order (i.e., Losses allocated pursuant to Section 7.1(b)(3) shall first be offset, Losses allocated pursuant to Section 7.1(b)(2) shall next be offset, and Losses allocated pursuant to Section 7.1(b)(1) shall be offset last); and

        (2)   second, to the Members in accordance with their respective Ownership Percentages.

        (b)    Losses.    Subject to Section 7.1(c), any Losses of the Company for any Fiscal Year or other period shall be allocated among the Members as follows:

        (1)   first, to the Members pro rata based on, and to the extent of, their respective Common Equity; and

        (2)   second, to the Members in accordance with their respective Ownership Percentages.

        (c)    Special Rules.    Notwithstanding the general allocation rules set forth in Sections 7.1(a) and (b), the following special allocation rules shall apply under the circumstances described:

        (i)    Limitation on Loss Allocations.    The Losses allocated to any Member pursuant to Section 7.1(b) with respect to any Fiscal Year shall not exceed the maximum amount of Losses that can be so allocated without causing such Member to have an Adjusted Capital Account Deficit at the end of such Fiscal Year if any other Member has a positive Capital Account balance. All Losses in excess of the limitation set forth in this Section 7.1(c)(i) shall be allocated (1) first, to those Members who will not be subject to this limitation, in the ratio that their Ownership Percentages bear to each other, and (2) second, any remaining amount to the Members in the manner required by the Code and the Regulations.

        (ii)    Qualified Income Offset.    If in any Fiscal Year a Member unexpectedly receives an adjustment, allocation or distribution described in Regulations Section 1.704-l(b)(2)(ii)(d)(4), (5) or (6), and such adjustment, allocation or distribution causes or increases an Adjusted Capital Account Deficit for such Member, then, before any other allocations are made under this Agreement or otherwise, such Member shall be allocated items of income and gain (consisting of a pro rata portion of each item of Company income, including gross income and gain) in an amount and manner sufficient to eliminate such Adjusted Capital Account Deficit as quickly as possible.

        (iii)    Company Minimum Gain Chargeback.    If there is a net decrease in Company Minimum Gain during any Fiscal Year, then, except as provided in Regulations Section 1.704-2(f)(2), (3) or (5), each Member shall be allocated items of income and gain for such Fiscal Year (and, if necessary, for subsequent Fiscal Years) in proportion to, and to the extent of, such Member's share

5

of the net decrease in Company Minimum Gain during such Fiscal Year. To the extent that this Section 7.1(c)(iii) is inconsistent with Regulations Section 1.704-2(f) or 1.704-2(k) or incomplete with respect to such Regulations, the Company Minimum Gain Chargeback provided for herein shall be applied and interpreted in accordance with such Regulations.

        (iv)    Member Nonrecourse Debt Minimum Gain Chargeback.    If there is a net decrease in Member Nonrecourse Debt Minimum Gain during any Fiscal Year, then, except as provided in Regulations Section l.704-2(i)(4), each Member shall be allocated items of income and gain for such Fiscal Year (and, if necessary, for subsequent Fiscal Years) in proportion to, and to the extent of, such Member's share of the net decrease in Member Nonrecourse Debt Minimum Gain during such Fiscal Year. For purposes of determining whether the Company has a net decrease in Member Nonrecourse Debt Minimum Gain, all increases and decreases, if any, of Member Nonrecourse Debt Minimum Gain allocated to the Company with respect to its interests in lower-tier partnerships (such as the Project Partnerships) in accordance with Regulations Section 1.704-2(k) shall be aggregated and netted with all such increases and decreases at the Company level. To the extent that this Section 7.1(c)(iv) is inconsistent with Regulations Section 1.704-2(i)(4) or 1.704-2(k) or incomplete with respect to such Regulations, the Member Nonrecourse Debt Minimum Gain chargeback provided for herein shall be applied and interpreted in accordance with such Regulations.

        (v)    Member Nonrecourse Deductions.    Member Nonrecourse Deductions shall be allocated among the Members in accordance with the ratios in which the Members share the economic risk of loss for the Member Nonrecourse Debt that gave rise to those deductions. This allocation is intended to comply with the requirements of Regulations Section 1.704-2(i) and shall be interpreted and applied consistent therewith.

        (vi)    Company Nonrecourse Deductions.    Nonrecourse deductions that are not related to Member Nonrecourse Debt shall be allocated to the Members in proportion to their respective Ownership Percentages.

        (vii)    Curative Allocations.    Any allocations of items of income, gain, or loss pursuant to Sections 7.1(c)(i)-(vi) hereof shall be taken into account in computing subsequent allocations pursuant to this Article VII, so that the net amount of any items so allocated and the income, losses, and other items allocated to each Member pursuant to this Article Vll shall, to the extent possible, be equal to the net amount that would have been allocated to each Member had no allocations ever been made pursuant to Sections 7.1(c)(i)-(vi).

        (viii)    Change in Regulations.    If the Regulations incorporating the allocations set forth in Sections 7.1(c)(i)-(vii) (the "Regulatory Allocations") are hereafter changed or if new Regulations are hereafter adopted, and such changed or new Regulations, in the opinion of tax counsel for the Company, make it necessary to revise the Regulatory Allocations or provide further special allocation rules in order to avoid a significant risk that a material portion of any allocation set forth in this Article VII would not be respected for Federal income tax purposes, the Members shall make such reasonable amendments to this Agreement as, in the opinion of such counsel, are necessary or desirable, taking into account the interests of the Members as a whole and all other relevant factors, to avoid or reduce significantly such risk to the extent possible without materially changing the amounts allocable and distributable to any Member pursuant to this Agreement.

        (ix)    Change in Members' Interests.    In the event of a transfer of a Membership Interest or a change in a Member's Ownership Percentage during any Fiscal Year, allocations among the Members shall be made in accordance with their Ownership Percentages from time to time during such Fiscal Year in accordance with Code Section 706, using the methodology determined by the Board of Directors, except that Depreciation shall be deemed to accrue ratably on a daily basis

6

over the entire Fiscal Year during which the corresponding asset is owned by the Company if such asset is placed in service prior to or during the Fiscal Year.

         (x)  Notwithstanding anything in this Agreement to the contrary, solely for purposes of computing the Profits and Losses allocable to MSW Holdings II and UAE XX XX (but not for purposes of computing any Profits or Losses allocable to MSW Xxxxxx or Duke Erie), the Profits and Losses allocable to MSW Holdings II and UAE XX XX shall be computed as if the Book Value of all Company assets had been adjusted as of June 30, 2003 to equal their respective fair market values in accordance with clause (ii) of the definition of Book Value herein (the "Hypothetical Revaluation"); any items of income, gain, loss, expense, or deduction that would have been allocable to either MSW Holdings II or UAE XX XX but that have not been allocated to either MSW Holdings II or UAE XX XX by reason of the Hypothetical Revaluation shall be specially allocated 99.8% to MSW Holdings II and 0.2% to UAE XX XX.

        (d)    Optional Capital Account Restoration Obligation.    Notwithstanding any other provision of this Agreement, if an item of loss, deduction, income or gain would be allocated from or to a Member in a manner other than in accordance with the Member's Ownership Percentage as a result of such Member having an Adjusted Capital Account Deficit, such Member shall be entitled, at its sole option, to elect to agree to unconditionally restore a deficit balance (or portion thereof) in its Capital Account by providing written notice of such election to the Company and the other Members such that such Member shall not incur an Adjusted Capital Account Deficit; provided, however, such Member may eliminate such deficit restoration obligation (in whole or in part) if, after such elimination, such Member does not then have an Adjusted Capital Account Deficit by providing written notice thereof to the Company and the other Member. This section is intended to meet the requirements of Regulations Section 1.704-1(b)(2) such that a Member shall not be denied an allocation of loss or deduction or be allocated income or gain as the result of an Adjusted Capital Account Deficit.

        (e)    Excess Nonrecourse Liabilities.    For purposes of calculating Members' shares of "excess nonrecourse liabilities" of the Company (within the meaning of Regulations Section 1.752-3), the Members intend that they be considered as sharing profits of the Company in proportion to their respective Ownership Percentages.

        Section 7.2    Tax Allocations.

        (a)    In General.    Except as set forth in Section 7.2(b), allocations for tax purposes of items of income, gain, loss, deduction, and credits, shall be made in the same manner as the applicable allocation of Profit or Loss set forth in Section 7.1. Allocations pursuant to this Section 7.2 are solely for purposes of Federal, state and local income 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, Distributable Cash or other distributions pursuant to any provision of this Agreement.

        (b)    Special Rules.

        (i)    Elimination of Book/Tax Disparities.    In determining a Member's allocable share of Company taxable income or tax loss, the Member's allocable share of each item of income, gain, loss and deduction shall be properly adjusted to reflect the difference between such Member's share of the adjusted tax basis and the Book Value of each of the Company assets used in determining such item. With respect to depreciation, for example, in determining the taxable income or tax loss allocable to a Member, Profits and Losses allocable to that Member shall be adjusted by eliminating Depreciation allocable to that Member and substituting therefor tax depreciation, amortization or other cost recovery deduction allocable to that Member determined by reference to that Member's share of the tax basis of Company assets. This provision is intended to comply with the requirements of Code Section 704(c) and Regulations

7

Section 1.704-l(b)(2)(iv)(f)(4) and shall be interpreted in conformity therewith. Any elections or other decisions relating to such tax allocations shall be made by the Board of Directors.

        (ii)    Tax Credits.    Any tax credits shall be allocated among the Members in accordance with Regulations Section l.704-l(b)(4)(ii), unless the applicable Code provision shall otherwise require.

        (c)    Conformity of Reporting.    The Members are aware of the income tax consequences of the allocations made by this Section 7.2 and hereby agree to be bound by the provisions of this Section 7.2 in reporting their shares of Company profits, gains, income, losses, deductions, credits and other items for income tax purposes.

        Section 7.3    Code Section 754 Election.    To the extent and at the times provided by law, the Board of Directors, on behalf of the Company, may elect in a timely manner pursuant to Section 754 of the Code and pursuant to corresponding provisions of applicable state and local tax laws, to adjust the tax bases of the assets of the Company pursuant to Sections 734 and 743 of the Code.

ARTICLE VIII

MANAGEMENT OF THE COMPANY

        Section 8.1    Board of Directors.

        (a)   The overall management and control of the Company shall be exercised by a board of directors elected by the Members ("Board of Directors"). The Board of Directors shall be empowered to set policy for, and to make all decisions on behalf of the Company, subject to the limitations set forth in this Agreement. The Board of Directors shall appoint such officers as it shall determine appropriate for the Company. Such officers shall hold office until death, resignation or removal, with removal at the pleasure of the Board of Directors. The Board of Directors may delegate such of its authorities and responsibilities to such officers.

        (b)   The Board of Directors shall hold such meetings as may be called by any director upon 10 days' prior written notice for meetings in person, or upon 24 hours' prior written notice for special telephonic or televideo meetings. When feasible, the Chairman and Chief Executive Officer, if any, shall provide the representatives on the Board of Directors with an agenda for each Board of Directors meeting reasonably in advance of such meeting. No director shall be entitled to compensation or reimbursement of expenses from the Company for attendance at such meetings. Any meeting of the Board of Directors may be held by conference telephone call, televideo arrangement or through similar communications equipment.

Unless the act of a greater number is required by law or this Agreement, the act of a majority of the directors present at any such meeting at which a quorum is present shall be the act of the Board of Directors.

        (d)   Any action required or permitted to be taken at a meeting of the Board of Directors may be taken without a meeting if all representatives on the Board of Directors consent thereto in writing. Such consents shall be filed with the minutes of the Board of Directors.

        Section 8.3    Liability for Certain Acts.    Each Member shall act in good faith with respect to the Company and with such care as an ordinary prudent person in a like position would use under similar circumstances.

No Member shall be liable to the Company or to any other Member for any loss or damage sustained by the Company or any Member, except for (i) any loss or damage resulting from intentional misconduct, gross negligence or a knowing violation of law by such Member or its officers, directors, agents or Affiliates, or (ii) a transaction for which such Member, or its officers, directors, agents or Affiliates received a personal benefit in violation or breach of the provisions of this Agreement. In no event shall any Member be liable to the Company or to any other Member for any indirect or consequential damages sustained by the Company or any other Member.

Neither the Company nor any Member shall have any right, by virtue of this Agreement, to share or participate in such other investments or activities of a Member or to the income or proceeds derived therefrom. A Member shall incur no liability to the Company or to any of the other Members as a result of engaging in any other business or venture.

        Section 8.5    Indemnity of Members, Employees and Other Agents.

        (a)   To the fullest extent permitted under the Act, the Company shall indemnify the Company's officers and employees, the representatives (including any alternates) on the Board of Directors and the other Members (and the respective officers, directors, employees, agents, members and stockholders of each of the foregoing) (each of the foregoing, an "Indemnitee") in connection with the management of the Company when the same shall be acting within the scope of their authority conferred by the provisions of this Agreement or pursuant to a duly authorized delegation of authority from the Board of Directors; provided that no such indemnification shall be available in respect of (i) any loss or damage to the extent that such loss or damage results from intentional misconduct, gross negligence or a knowing violation of law by the party seeking indemnification or its Affiliate or (ii) a transaction for which the Person seeking indemnity hereunder or its Affiliate received a personal benefit in violation or breach of the provisions of this Agreement.

        (b)   To the extent that an Indemnitee is successful on the merits or otherwise in any Proceeding (as hereafter defined), such Indemnitee shall be indemnified by the Company against all expenses actually and reasonably incurred by such Indemnitee or on such Indemnitee's behalf in connection therewith. If an Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all Claims, issues or matters in such Proceeding, the Company shall indemnify such Indemnitee against all expenses actually and reasonably incurred by him or on his behalf in connection with each successfully resolved Claim, issue or matter. For purposes of this Section 8.5(b) and without limitation, the termination of any Claim, issue or matter in such a Proceeding by dismissal or withdrawal with or without prejudice, shall be deemed to be a successful result as to such Claim, issue or matter. For purposes of this Section 8.5, "Proceeding" includes any action, suit, arbitration, alternate dispute resolution mechanism, investigation, administrative hearing and any other proceeding (including any appeals from any of the foregoing) whether civil, criminal,

9

administrative or investigative that arise out of or otherwise relate to this Agreement and the terms hereof.

        (c)   The Company shall advance all reasonable expenses incurred by or on behalf of an Indemnitee in connection with any Proceeding within 20 days after the receipt by the Company of a statement or statements from the Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the expenses incurred by the Indemnitee and shall include or be preceded or accompanied by an undertaking by or on behalf of any Indemnitee to repay any expenses advanced if it shall ultimately be determined that such Indemnitee is not entitled to be indemnified against such expenses.

        Section 8.6    Compensation.    No Member shall be entitled to compensation for actions taken on behalf of the Company; however, Members shall be reimbursed for all reasonable and necessary expenses incurred on behalf of the Company if provided for in the operating budget of the Company.

ARTICLE IX

RIGHTS AND OBLIGATIONS OF MEMBERS

        Section 9.1    Limitation on Liability and Authority.    Each Member's liability shall be limited as set forth in this Agreement, the Act and other applicable law. Each Member agrees that it will not exercise its authority under the Act to bind or commit the Company to agreements, transactions or other arrangements, or hold itself out as an agent of the Company, unless such Member is acting expressly within the scope of its authority under this Agreement or an express duly authorized delegation of authority by the Board of Directors.

        Section 9.2    No Liability for Company Obligations.    No Member will have any liability for any debts or losses of the Company except as provided by law relating to liability for wrongful distributions or pursuant to Section 7.1(d) relating to a Member's Capital Account restoration option.

        Section 9.3    Priority and Return of Capital.    Except as is expressly provided herein, no Member shall have priority over any other Member, either as to the return of Capital Contributions or as to Profits, Losses, or distributions.

        Section 9.4    Waiver of Conflicts.    To the fullest extent permitted by law, each Member hereby waives any conflicts of interest of UAE and its Affiliates (including MSW Holdings II), of each other Member and its Affiliates, and of each of their respective members, shareholders, directors, officers and employees (each, a "Related Party") arising out of or relating to any relationships between a Related Party and its Affiliates, currently existing or hereafter arising, including without limitation the activities of any Related Party or Affiliates of any Related Party as a provider of credit support under the Equity Contribution Agreement. In each case, the Related Party shall have the same rights and powers in its relevant capacity as would an unrelated third party and may exercise such rights and powers without regard to such other capacities and as though such Related Party were not a party to this Agreement, all without liability for any duties owed in such other capacities or for any benefits derived by any other Related Person in such other capacities.

        Section 9.5    Regulatory Matters.

        (a)   None of UAE Holdings, UAE, MSW Holdings II, UAE XX XX, MSW Xxxxxx, Xxxx Erie nor any other Member of the Company shall take any action, and each shall use commercially reasonable efforts to prevent any third-party action within its reasonable control, if such action would result in an Adverse QF Event or an Adverse PUHCA Event. Each of UAE Holdings, UAE, MSW Holdings II, UAE XX XX, MSW Xxxxxx, Xxxx Erie and each other Member of the Company hereby agrees to

10

cooperate with any affected Member, and to use all commercially reasonable efforts, to remedy any Adverse QF Event or Adverse PUHCA Event. Each of UAE Holdings, UAE, MSW Holdings II, UAE XX XX, MSW Xxxxxx, Xxxx Erie and each other Member of the Company agrees to use commercially reasonable efforts not to acquire any interest in any electric utility or electric utility holding company that would result in an Adverse QF Event. Subject to the requirements above, in connection with any Transfer, MSW Holdings II, UAE XX XX, MSW Xxxxxx, Xxxx Erie and their respective Subsidiaries, or any other Member and any Subsidiary of such Member, as applicable, will request that the proposed assignee represent either (i) that to its knowledge it does not have any stockholders who are "public utility companies" or "holding companies" within the meaning of PUHCA (and if such transferor is a publicly owned corporation or a subsidiary of a publicly owned corporation, it may rely on the fact that publicly available 13(d) or 13(g) documents do not reveal ownership by "public utility companies" or "holding companies") or (ii) if it does know of such stockholders who are "public utility companies" or "holding companies," the amount of such ownership by such stockholders in such assignee. Unless otherwise required by law, none of MSW Holdings II, UAE XX XX, MSW Xxxxxx, Xxxx Erie or their respective Subsidiaries, or any other Member or any Subsidiary of such Member will consummate any Transfer if based on the information received by MSW Holdings II, UAE XX XX, MSW Xxxxxx, Xxxx Erie or such other Member, set forth above, such Transfer would result in an Adverse QF Event or if MSW Holdings II, UAE XX XX, MSW Xxxxxx, Xxxx Erie or such other Member or one of their respective Subsidiaries otherwise has knowledge that such Transfer would result in an Adverse QF Event. If any party breaches the covenants set forth in this Section 9.5(a), then the other parties shall be entitled to such relief at law or in equity as may be awarded by a court of competent jurisdiction.

        (b)   Each of the Members agrees to cause the Project Partnerships to file an application for each of the waste-to-energy projects of the Project Partnerships to be designated as an exempt wholesale generator under PUHCA and to use commercially reasonable efforts to secure such designation.

Copies of all notices and other information received by the tax matters partner shall promptly be given to all Members.

12

Membership Interest (any transaction described in clauses (i) or (ii), a "Transfer"), in each case without the prior consent of any other Member.

        (b)   All Transfers hereunder shall be by instrument (including in the case of a merger or business combination the relevant agreement or plan of merger or combination), in form and substance reasonably satisfactory to the Company, which instrument shall contain an express statement by the transferee of its agreement to accept, adopt and be bound by all of the terms and provisions of this Agreement, as the same may have been amended from time to time, which shall include a Certificate duly endorsed for transfer by the transferring Member and delivered to the Company. All Transfers shall provide for the payment by the transferring Member of all reasonable expenses incurred by the Company in connection with such Transfer, including, without limitation, the necessary amendments to this Agreement to reflect such Transfer.

In no event shall the Company dissolve or terminate pursuant to Section 708 of the Code or otherwise upon the admission of any Member to the Company or upon any permitted Transfer of an interest in the Company by any Member.

        (c)   Notwithstanding anything to the contrary in this Agreement, at law or in equity, no Member shall Transfer or otherwise affect any Membership Interest in a way that would cause a default under any material agreement, license, permit or other instrument of any kind whatsoever to which the Company is a party or by which it is bound or that would cause, or might be reasonably expected to cause, an Adverse PUHCA Event or an Adverse QF Event. In addition, without the consent of the other Members, no Transfer (whether to a Subsidiary or otherwise) shall relieve or release the assigning Member from any of its obligations under this LLC Agreement or the Equity Contribution Agreement, except as permitted thereunder.

The property of the Company shall be liquidated as promptly as is consistent with obtaining the fair value thereof. If any assets are to be distributed in kind, the Liquidating Trustee shall ascertain the Fair Market Value of such assets (based upon a single appraisal, in the case of a disagreement, at the expense of the Company). Each Member's Capital Account shall be charged or credited, as the case may be, for the net gain or net loss on the sale of the assets or in the case of an in-kind distribution, any net gain or net loss deemed recognized on such deemed sale, as if such asset had been sold for cash at such Fair Market Value and the net gain or net loss recognized thereby shall be allocated to and among the Members in accordance with Article VII.

        (iv)  thereafter, to the Members in accordance with their respective Ownership Percentages.

        Section 12.4    Certificate of Cancellation.    When all debts, liabilities and obligations of the Company have been paid and discharged or adequate provisions have been made therefor and all of the remaining property and assets of the Company have been distributed to the Members, a Certificate of Cancellation shall be executed and filed with the Secretary of State of Delaware in accordance with Section 18-203 of the Act.

        Section 12.5    Return of Contribution; Nonrecourse Against Other Members.    Except as provided by law or as expressly provided in this Agreement, upon dissolution, each Member shall look solely to the assets of the Company for the return of its Capital Contribution.
