THIRD AMENDMENT TO LLC AGREEMENT

THIS THIRD AMENDMENT TO LLC AGREEMENT (this "Amendment") is made and entered into as of June 30, 2003 by and between DUKE ENERGY ▇▇▇▇▇▇, LLC, a Delaware limited liability company ("▇▇▇▇ ▇▇▇▇▇▇"), DUKE ENERGY ERIE, LLC, a Delaware limited liability company ("Duke Erie"), UAE REF-FUEL LLC, a Delaware limited liability company ("UAE RF") and UAE REF-FUEL II CORP., a Delaware Corporation and a wholly owned subsidiary of UAE RF ("UAE ▇▇ ▇▇").

W I T N E S S E T H:

WHEREAS, pursuant to the Amended and Restated Limited Liability Company Agreement, dated as of April 30, 2001, between UAE RF and Duke Energy Global Markets, Inc., a Nevada corporation ("Duke RF") (as amended, modified and supplemented through the date hereof, the "LLC Agreement"), each of Duke RF and UAE RF owned 50% of the membership interests in Duke/UAE Ref-Fuel LLC (the "Company"); and

WHEREAS, pursuant to the Contribution to Capital, Assignment and Assumption Agreement, dated as of June 20, 2003, among Duke RF, Duke Erie and ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ ▇▇ transferred and assigned (i) a 49.8% membership interest in the Company to ▇▇▇▇ ▇▇▇▇▇▇; and (ii) a 0.2% membership interest in the Company to Duke Erie (such transfers and assignments, the "Duke Transfers"); and

WHEREAS, pursuant to the Contribution to Capital, Assignment and Assumption Agreement, dated as of June 30, 2003, between UAE RF and UAE ▇▇ ▇▇ and executed concurrently herewith, UAE RF transferred and assigned a 0.1% interest in the capital of the Company, effective June 30, 2003 (the "UAE Transfer Date"), to UAE ▇▇ ▇▇ and, as a result of the concurrent execution of this Amendment, a 1% interest in all Profits and Losses of the Company realized after the date hereof, with such future Profits and Losses being determined solely for this purpose as if the Book Value of all Company assets had been adjusted as of the date hereof to equal their respective fair market values in accordance with clause (ii) of the definition of "Book Value" in the LLC Agreement (such transfer and assignment, the "UAE Transfer"). For purposes of this Amendment, the term "interest in the capital of the Company" means an amount that is equal to the Company's liquidation value at the time of the UAE Transfer, i.e., an amount that is equal to the total distributable proceeds available within the Company assuming that all of the Company's assets were sold for their Fair Market Value and after all of the Company's liabilities are paid as of such date. It is the intention of the parties hereto that "interest in the capital of the Company" be interpreted in a manner that is consistent with the term "capital interest" as defined in Internal Revenue Procedure 93-27); and

WHEREAS, as a result of the Duke Transfers, ▇▇▇▇ ▇▇▇▇▇▇ owns a 49.8% membership interest in the Company and Duke Erie owns a 0.2% membership interest in the Company; and

WHEREAS, as a result of the UAE Transfer, UAE RF owns a 49.9% interest in the capital of the Company and has a right and obligation that is equal to 49% of the Profits and Losses of the Company realized after the date hereof and computed as described above, and UAE ▇▇ ▇▇ owns a 0.1% interest in the capital of the Company and has a right and obligation to receive 1% of the Profits and Losses of the Company realized after the date hereof and computed as described above; and

WHEREAS, neither ▇▇▇▇ ▇▇▇▇▇▇'▇ nor Duke Erie's percentage interest in or right to receive Profits, Losses and Distributable Cash or distributions of the Company will be changed or modified in any way as a result of the UAE Transfer; and

WHEREAS, ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ Erie, UAE RF and UAE ▇▇ ▇▇ desire to amend the LLC Agreement in order to reflect the transfers discussed above.

NOW, THEREFORE, in consideration of the mutual covenants contained herein and other valuable consideration, the receipt, adequacy and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows:

Capitalized terms used and not defined herein shall have the meanings assigned to them in the LLC Agreement.

WHEREAS, the parties hereto desire to amend certain provisions of the LLC Agreement; and

WHEREAS, the parties hereto constitute all of the parties to the LLC Agreement.

NOW THEREFORE, in consideration of the premises, the parties hereto intending legally to be bound hereby agree as follows:

Section 1. Amendments.

(A) Section 8.1 of the LLC Agreement is hereby amended in its entirety to read as follows:

"Section 8.1 Board of Directors.

(a) The overall management and control of the Company shall be exercised by a committee appointed by the Members (the "Board of Directors"). For as long as Duke RF and UAE RF each own a 50% Ownership Percentage, the Board of Directors shall consist of four individuals appointed by Duke RF, four individuals appointed by UAE RF and the Chairman and Chief Executive Officer of the Company. Upon the admission of any new Member, the Board of Directors shall be reconstituted so that each Member (including the new Member) shall appoint a number of individuals to the Board of Directors equal to its Ownership Percentage divided by 12.5, rounded to the nearest whole number, but not less than one. Each representative on the Board of Directors shall be a senior officer of the Member (or an Affiliate of such Member) appointing him or her. The representatives on the Board of Directors appointed by each Member shall together have a single vote equal to the Ownership Percentage of the Member that appointed such representatives. The Chairman and Chief Executive Officer shall be a non-voting member of the Board of Directors. Any of a Member's representatives may cast such Member's vote on the Board of Directors whether one or more of such representatives is present at any meeting of the Board of Directors. Each, representative on the Board of Directors shall hold office until death, resignation or removal at the pleasure of the Member that appointed such representative of the Board of Directors. If a vacancy occurs on the Board of Directors, the Member that appointed such vacating representative shall appoint a successor. Each Member may also designate an alternate who shall be authorized to act in the absence of the representative for whom he or she is an alternate. Each alternate shall also hold office until death, resignation or removal at the pleasure of the appointing Member. The initial representatives and alternates of the Board of Directors and their successors shall be appointed by the respective Members by written notice to the other Members. 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 may delegate such of its authorities and responsibilities to a Member or any other party as the Board of Directors may elect. 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 to be at the pleasure of the Board of Directors.

(b) The Board of Directors shall hold such meetings as may be called by any Board of Directors representative upon 10 days' prior written notice for meetings in person, or upon 24 hours' prior written notice for special telephonic or televideo meetings; provided, however, that a

valid meeting of the Board of Directors may be held in the absence of such notice, or upon shorter notice, if at least one representative of each Member on the Board of Directors attends or participates in such meeting. 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 Board of Directors representative or alternate 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. Participation in a meeting via telephone or televideo shall constitute presence in person at such meeting. The Chairman and Chief Executive Officer, if any, shall keep and maintain minutes of each meeting of the Board of Directors with the other books and records of the Company.

(c) 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.

(d) The Board of Directors may take action on a matter at a meeting only if representatives designated by Members holding a majority of the Ownership Percentages are present in person or by proxy (a "Quorum"). Once a Member is represented for any purpose at a meeting, such Member is deemed present for Quorum purposes for the remainder of the meeting and for any adjournment of that meeting unless a new record date is or must be set for that adjourned meeting. In the absence of a Quorum at the opening of any meeting of the Board of Directors, such meeting may be adjourned from time to time by the vote of Members holding not less 51% of the Ownership Percentages cast on the motion to adjourn.

(e) All actions of the Board of Directors shall require the affirmative vote of representatives designated by Members holding a majority of the Ownership Percentages; provided, however, that for as long as Duke RF and UAE RF each own a 50% Ownership Percentage, all actions shall require the affirmative vote of at least one representative on the Board of Directors representing Duke RF and at least one representative on the Board of Directors representing UAE RF. The Members shall not vote their Membership Interests directly except as required under the Act, and the Preferred Interests shall have no voting rights.

(f) In the event that any Member ceases to be a Member of the Company for any reason whatsoever, the representatives on the Board of Directors appointed by such Member shall immediately cease to be representatives on the Board of Directors.

(g) Subject to such supervisory powers, if any, as may be exercised by the Board of Directors, the Chairman and Chief Executive Officer, if any, shall be the chief executive officer of the Company and, if present, shall preside at meetings of the Board of Directors, and shall see that all orders and resolutions of the Members and Board of Directors are carried into effect. The Chairman and Chief Executive Officer, if any, shall, subject to the control of the Board of Directors, have the general powers and duties of management usually vested in the office of the chairman and chief executive officer of a corporation and shall exercise and perform such other powers and duties as may be from time to time prescribed by the Board of Directors or prescribed by this Agreement. The Chairman and Chief Executive Officer, if any, shall have the power to execute bonds, mortgages and other contracts on behalf of the Company, except where required or permitted by law to be otherwise signed and executed and except where the signing and execution thereof shall be expressly delegated by the Board of Directors to some other officer or agent of the Company to the exclusion of the Chairman and Chief Executive Officer, if any.

(h) Subject to such supervisory powers, if any, as may be exercised by the Board of Directors or assigned by the Board of Directors to the Chairman and Chief Executive Officer, the President, if any, shall be the chief operating officer of the Company, shall, if present and in the absence of

the Chairman and Chief Executive Officer, preside at meetings of the Board of Directors and shall, subject to the control of the Board of Directors, have general and active management of the business of the Company. The President, if any, shall have the general powers and duties of management usually vested in the office of the president of a corporation and shall exercise and perform such other powers and duties as may be from time to time prescribed by the Board of Directors or prescribed by this Agreement. The President, if any, shall have the power to execute bonds, mortgages and other contracts on behalf of the Company, except where required or permitted by law to be otherwise signed and executed and except where the signing and execution thereof shall be expressly delegated by the Board of Directors to some other officer or agent of the Company to the exclusion of the President."

(B) The definition of "Management Committee" set forth in Appendix A to the LLC Agreement is hereby amended in its entirety to read as follows:

"'Board of Directors' means the committee established in accordance with Section 8.1(a) of the LLC Agreement."

(C) The LLC Agreement is hereby amended so that all references to "Management Committee" in the LLC Agreement shall be read as "Board of Directors".

Section 2. Effective Date. The amendments to the LLC Agreement set forth above shall be effective as of the date hereof.

Section 3. Miscellaneous.

(A) Except as expressly amended and modified by this Amendment, the LLC Agreement shall continue to be in full force and effect in accordance with its terms.

(B) This Amendment may be executed in any number of counterparts, and each such counterpart shall for all purposes be an original and all counterparts shall together constitute one and the same instrument.

(C) This Amendment shall be governed by, and construed and interpreted in accordance with, the internal laws of the State of Delaware without regard to the principles of conflicts of laws thereof.

IN WITNESS WHEREOF, the parties hereto have caused this Second Amendment to the LLC Agreement to be duly executed and delivered as of the date first written above.

CONTRIBUTIONS TO THE COMPANY

Section 5.1 Capital Contributions.

As of the Effective Date, as a result of the purchase by UAE RF of the Purchased Interests pursuant to the LLC Interest Purchase Agreement, the Ownership Percentages of the Members are as set forth on Exhibit B hereto. As of the Effective Date, immediately after such

purchase, the Members made the Capital Contributions to the Company set forth under the caption "Effective Date Capital Contributions" on Exhibit A hereto, and following such capital contributions the Ownership Percentages of the Members remained as set forth on Exhibit D hereto.

Section 5.2 Additional Capital Contributions.

(a) Each Member shall make its proportionate share, based on_. its respective Ownership Percentage, of such Additional Capital Contributions (i) as the Management Committee shall determine to be necessary (other than with respect to Additional Capital Contributions required pursuant to clause (ii) below) or (ii) as required to meet such Member's obligations under the Equity Contribution Agreement. The Management Committee, in the case of Additional Capital Contributions pursuant to clause (i) hereof, shall give the Members reasonable prior notice of the amount of the Additional Capital Contribution and the Capital Call Date. The notice provisions of the Equity Contribution Agreement shall govern the timing of Additional Capital Contributions pursuant to clause (ii) above. When determining the number of days of prior notice for Additional Capital Contributions made pursuant to clause (i) above, the Management Committee may consider the needs of the Company for the contribution, and in no event shall such prior notice need to be longer than 30 days. If a Member does not make any required Additional Capital Contribution pursuant to this Section 5.2(a), then such noncontributing Member hereby consents to the application to it of the remedies provided in Section 5.2(c), and further agrees that the availability or exercise, or both, of such remedies shall not preclude, limit, or restrict any other remedies that maybe available at law, in equity, by statute, or otherwise in respect of any failure by such non-contributing member to make any such Additional Capital Contribution. Additional Capital Contributions made pursuant to Section 5.2(a)(i) or (ii) shall be made for Preferred Interests as further set forth in this Section 5.2.

(b) All Additional Capital Contributions shall be Tendered and made on or before the respective Capital Call Date. Upon the making of Additional Capital Contributions, each Member's respective Capital Account shall be adjusted appropriately as provided herein. Absent the approval of the Management Committee or as otherwise provided in this Article V, all Additional Capital Contributions made by the Members shall be made pro rata based upon their Ownership Percentages, and no Additional Capital Contribution shall result in any modification to the Ownership Percentages of the Members.

(c) In addition to the rights provided under Section 5.2(e), if a Member (the "Non-Contributing Member") does not Tender, on or before the Capital Call Date, an Additional Capital Contribution it is required to make pursuant to Section 5.2(a), each Member who has Tendered its related Additional Capital Contribution (each, a "Contributing Member"), shall have the right, but not the obligation, exercisable within 180 days after the Capital Call Date, to do any or all of the following: (i) refuse to make or withdraw all or part of such Contributing Member's Additional Capital Contribution (and such withdrawn Additional Capital Contribution shall be deemed to have never been made), (ii) make a Capital Contribution Loan in the amount of the Contributing Member's Additional Capital Contribution, and (iii) make a Capital Contribution Loan for all or part of the Non-Contributing Member's Additional Capital Contribution.

A "Capital Contribution Loan" is a Member Loan for all or part of an Additional Capital Contribution, (A) that shall have a term determined by the Member making the Loan, which shall be at least one year, (B) that shall bear interest at an interest rate equal to 15% per annum, (C) that shall be mandatorily prepaid by the Company out of Distributable Cash before any distributions are made to the Members pursuant to Section 6.1, (D) all or any portion of which (including accrued and unpaid interest) shall be convertible, at the option of the Contributing Member, at any time and from time to time during the first year of the term of such Capital Contribution Loan, into Preferred Interests with an Unreturned Capital Balance equal to the amount of the outstanding principal and accrued and unpaid interest so converted; provided, however, that such conversion shall not cause an Adverse QF Event or an Adverse PUHCA Event, (E) all or any portion of which shall be assignable pursuant to Section 5.2(e), and (F) which shall be represented by a promissory note substantially in the form of Exhibit C (a "Note"). Any such conversion to Preferred Interests shall be effective immediately upon

the giving of notice thereof by the Contributing Member (or any permitted assignee of such Capital Contribution Loan) to the Company and the Non-Contributing Member, which notice shall specify the amount of principal and interest so converted. The Company shall execute such Note and execute such other documents and instruments and take such further actions as are required by the Contributing Member to give effect to this Section 5.2(c).

If more than one Contributing Member elects to make a Capital Contribution Loan, such Contributing Members shall be entitled to make such Loans in accordance with their Ownership Percentages.

(d) If a Member fails to make an Additional Capital Contribution, the Management Committee (upon the vote of representatives of Members holding a majority of the Ownership Percentage exclusive of the Ownership Percentage of the Non-Contributing Member) may cancel the requested Additional Capital. Contribution at any time prior to the date any Capital Contribution Loans in respect of such Additional Capital Contributions are funded. If any capital call is cancelled after one or more Members has contributed an Additional Capital Contribution, such contributions shall immediately be returned to the Contributing Members.

(e) Any Contributing Member shall be permitted to assign its rights and remedies under Section 5.2(c) and any Capital Contribution Loan and Note in respect thereof to any Person (including the right to convert such loan into a Preferred Interest); provided; however, that such assignment will not result in an Adverse QF Event or an Adverse PUHCA Event for the Company or any Member.

Section 5.3 No Withdrawal of Capital. Except as specifically provided in this Agreement, no Member shall have the right to withdraw all or any part of its Capital Contributions from the Company, nor shall any Member have any right to demand and receive property other than cash as a return of its Capital Contributions. Except as specifically provided in this Agreement, no Member shall have the right to receive interest on its Capital Contributions or its Capital Account.

Section 5.4 Required Capital Contributions. No Member shall have any obligation to make any Capital Contributions to the Company other than as expressly set forth herein. In particular, no Member shall have any obligation to restore (to the Company or to any creditor of the Company) any deficit balance in its Capital Account at any time, whether on liquidation or otherwise, and such deficit balance shall not be considered a debt owed by Such Member to the Company or to any other Person for any purpose whatsoever.

Section 5.5 Member Loans. One or more Members may make loans (a "Member Loan") to the Company at such times and in such amounts as shall be authorized by the Management Committee or as provided in Section 5.2; provided, however, that no Member shall be required to make any Member Loan. No Member Loan shall be treated as a Capital Contribution for any purpose under this Agreement, nor shall any Member Loan (other than a Capital Contribution Loan) entitle a Member to any increase in its share of the Profits, Losses, Distributable Cash, or other distributions of the Company. Each Member Loan shall be repayable at such time or times, shall bear interest at such rate, and shall otherwise have such terms and conditions as shall be provided in this Agreement or as shall otherwise be agreed to by the lending Member and the Management Committee; provided, however, that without unanimous consent of the Management Committee, no Member Loan (other than a Capital Contribution Loan) shall prohibit distributions by the Company except during any time when there are amounts that are due and payable on such Member Loan.

Section 5.6 Maintenance of Capital Accounts.

(a) A Capital Account shall be established and maintained for each Member.

(b) Each Member's Capital Account (i) shall be increased by (A) the amount of money contributed by such Member to the Company, (B) the Fair Market Value of property contributed by such Member to the Company (net of liabilities secured by such contributed property that the Company is considered to assume or take subject to under Section 752 of the Code) and (C) allocations to such Member of Company income and gain (or items thereof), including income and

gain exempt from tax and income and gain described in Section 1.704-1(b)(2)(iv)(g) of the Regulations, but excluding income and gain described in Section 1.704-1(b)(4)(i) of the Regulations or allocated to a Member pursuant to Section 704(c) of the Code, and (ii) shall be decreased by (A) the amount of money distributed to such Member by the Company (B) the Fair Market Value of property distributed to such Member by the Company (net of liabilities secured by such distributed property that such Member is considered to assume or take subject to under Section 752 of the Code), after adjusting each Member's Capital Account by such Member's share of the unrealized income, gain, loss and deduction inherent in such property and not previously reflected in such Capital Account, as if the property had been sold for its then Fair Market Value on the date of distribution, (C) allocations to such Member of expenditures of the Company described in Section 705(a)(2)(B) of the Code and (D) allocations of Company loss and deduction (or items thereof), including loss and deduction described in Section 1.704-1(b)(2)(iv)(g) of the Regulations, but excluding items described in clause (ii)(C) of this Section 5.6(b) and loss or deduction described in Section 1.704-1(b)(4)(i) or Section 1.704-1(b)(4)(iii) of the Regulations. The Members' Capital Accounts also shall be maintained and adjusted as permitted by the provisions of Section 1.704-1(b)(2)(iv)(f) of the Regulations and as required by the other provisions of Section 1.704-1(b)(2)(iv) and Section 1.704-1(b)(4) of the Regulations, including adjustments to reflect the allocations to the Members of depreciation, depletion, amortization and gain or loss as computed for book purposes with respect to property contributed to the Company, rather than the allocation of the corresponding items, as computed for tax purposes, as required by Section 1.704-1(b)(2)(iv)(g) of the Regulations. Upon the transfer of all or part of an interest in the Company, the Capital Account of the transferor that is attributable to the transferred interest in the Company shall carry over to the transferee Member in accordance with the provisions of Section 1.704-1(b)(2)(iv)(1) of the Regulations, except as otherwise required to satisfy Section 1.704-1(b) of the Regulations in connection with a termination of the Company under Section 708(b)(1)(B) of the Code.

(c) In the event the Management Committee shall determine that it is prudent to modify the manner in which the Capital Accounts, or any debits or credits thereto (including, without limitation, debits or credits relating to liabilities that are secured by contributed or distributed property or that are assumed by the Company or the Members) are computed in order to comply with the Code and the Regulations, the Management Committee may make such modification; provided, that, in the good faith judgment of the Management Committee, it is not likely to have a material adverse effect on the amounts distributable or the timing of distributions to any Member. The Management Committee also shall (i) make any adjustments that are necessary or appropriate to maintain equality between (A) the Capital Accounts of the Members and (B) the amount of Company capital reflected on the Company's balance sheet, as computed for book purposes, in accordance with Section 1.704-1(b)(2)(iv)(g) of the Regulations, and (ii) make any appropriate modifications in the event unanticipated events might otherwise cause this Agreement not to comply with Section 1.704-1(b) of the Regulations.

Such determination shall be conclusively evidenced by the signature of an Authorized Signatory on such Certificate.

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);

(2) second, to the Members holding Preferred Interests pro rata based on, and to the extent of, their respective Unallocated Preferred Returns; and

(3) third, 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;

(2) second, to the Members pro rata based on, and to the extent of, their respective Preferred Equity; and

(3) third, 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 Membership Interests 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 1.704-1(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 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 1.7042(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 1.704-2(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 VIII, 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 VII 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 Management Committee, except that Depreciation shall be deemed to accrue ratably on a daily basis 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.

(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 Section 1.704-1(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 Management Committee.

(ii) Tax Credits. Any tax credits shall be allocated among the Members in accordance with Regulations Section 1.704-1(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 Management Committee, 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 Management Committee.

(a) The overall management and control of the Company shall be exercised by a committee appointed by the Members (the "Management Committee"). For as long as Duke RF and UAE RF each own a 50% Ownership Percentage, the Management Committee shall consist of three individuals appointed by Duke RF and three individuals appointed by UAE RF. Upon the admission of any new Member, the Management Committee shall be reconstituted so that each Member (including the new Member) shall appoint a number of individuals to the Management Committee equal to its Ownership Percentage divided by 16²/3, rounded to the nearest whole number, but not less than one. Each representative on the Management Committee shall be a senior officer of the Member (or an Affiliate of such Member) appointing him or her. The representatives on the Management Committee appointed by each Member shall together have a single vote equal to the Ownership Percentage of the Member that appointed such representatives. Any of a Member's representatives may cast such Member's vote on the Management Committee whether one or more of such representatives is present at any meeting of the Management Committee. Each representative on the Management Committee shall hold office until death, resignation or removal at the pleasure of the Member that appointed such

representative of the Management Committee. If a vacancy occurs on the Management Committee, the Member that appointed such vacating representative shall appoint a successor. Each Member may also designate an alternate who shall be authorized to act in the absence of the representative for whom he or she is an alternate. Each alternate shall also hold office until death, resignation or removal at the pleasure of the appointing Member. The initial representatives and alternates of the Management Committee and their successors shall be appointed by the respective Members by written notice to the other Members. The Management Committee 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 Management Committee may delegate such of its authorities and responsibilities to a Member or any other party as the Management Committee may elect. The Management Committee shall appoint such officers as it shall determine appropriate for the Company. Such officers shall hold office until death, resignation or removal, with removal to be at the pleasure of the Management Committee.

(b) The Management Committee shall hold such meetings as may be called by any Management Committee representative upon 10 days' prior written notice for meetings in person, or upon 24 hours' prior written notice for special telephonic or televideo meetings; provided, however, that a valid meeting of the Management Committee may be held in the absence of such notice, or upon shorter notice, if at least one representative of each Member on the Management Committee attends or participates in such meeting. When feasible, the Chairman and Chief Executive Officer, if any, shall provide the representatives on the Management Committee with an agenda for each Management Committee meeting reasonably in advance of such meeting. No Management Committee representative or alternate shall be entitled to compensation or reimbursement of expenses from the Company for attendance at such meetings. Any meeting of the Management Committee may be held by conference telephone call, televideo arrangement or through similar communications equipment. Participation in a meeting via telephone or televideo shall constitute presence in person at such meeting. The Chairman and Chief Executive Officer, if any, shall keep and maintain minutes of each meeting of the Management Committee with the other books and records of the Company.

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

(d) The Management Committee may take action on a matter at a meeting only if representatives designated by Members holding a majority of the Ownership Percentages are present in person or by proxy (a "Quorum"). Once a Member is represented for any purpose at a meeting, such Member is deemed present for Quorum purposes for the remainder of the meeting and for any adjournment of that meeting unless a new record date is or must be set for that adjourned meeting. In the absence of a Quorum at the opening of any meeting of the Management Committee, such meeting may be adjourned from time to time by the vote of Members holding not less 51% of the Ownership Percentages cast on the motion to adjourn.

(e) All actions of the Management Committee shall require the affirmative vote of representatives designated by Members holding a majority of the Ownership Percentages; provided, however, that for as long as Duke RF and UAE RF each own a 50% Ownership Percentage, all actions shall require the affirmative vote of at least one representative on the Management Committee representing Duke RF and at least one representative on the Management Committee representing UAE RF. The Members shall not vote their Membership Interests directly except as required under the Act, and the Preferred Interests shall have no voting rights

(f) In the event that any Member ceases to be a Member of the Company for any reason whatsoever, the representatives on the Management Committee appointed by such Member shall immediately cease to be representatives on the Management Committee.

(g) Subject to such supervisory powers, if any, as may be exercised by the Management Committee, the Chairman and Chief Executive Officer, if any, shall be the chief executive officer of the Company and, if present, shall preside at meetings of the Management Committee, and shall see that all orders and resolutions of the Members and Management Committee are carried into effect.

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 has guaranteed nor shall it have any obligation with respect to the return of a Member's Capital Contributions, and no Member has guaranteed profits from the operation of the Company.

Section 8.4 No Exclusive Duty to Company.

(a) A Member shall not be required to tend to the business and affairs of the Company as such Member's sole and exclusive function, and any Member may have other business interests and may engage in other activities in addition to those relating to the Company, including those that may be in competition with the Company or any of its Members.

liability to the Company or to any of the other Members as a result of engaging in any other business or venture.

(b) Notwithstanding Section 8.4(a), no Member nor any Affiliate of such a Member, shall own or acquire any equity interest in a Facility in the United States unless such Member or its Affiliate first offers (a "Facility Investment Offer") the opportunity to acquire such equity interest to the Company at the same price and on substantially the same terms and conditions as (or more favorable terms and conditions than) are available to such Member or its Affiliate. The offering Member or Affiliate shall notify the Company in writing, in reasonable detail (which writing may be a preliminary term sheet setting forth the general terms and conditions of the proposed transaction), of any Facility Investment Offer and shall provide to the Company such information as the Company may reasonably request in order to evaluate such offer, subject to any confidentiality agreement or other restriction applicable to the offering Member or Affiliate. The determination by the Company as to whether to accept or decline any Facility Investment Offer shall be made by a vote of the. Members holding a majority of the Ownership Percentages, exclusive of the Ownership Percentage of the Member who makes, or whose Affiliate makes, the Facility Investment Offer. Such determination shall be communicated to the offering Member in writing within 20 Business Days of receipt by the Company of the Facility Investment Offer. If (i) the Company declines such Facility Investment Offer, (ii) the Company accepts such Facility Investment Offer and fails, for any reason, within 60 days of the date of acceptance by the Company of such Facility Investment Offer, to enter into a binding agreement with third parties to effect such acquisition of or investment in the equity interest or (iii) the Company enters into a binding agreement with third parties, but fails, for any reason, within 180 days of the date of the binding agreement (or within three years of the date of the binding agreement if such acquisition or investment is in the construction or development of a new Facility) to complete such acquisition or investment, then the Member who made such offer, or any Affiliate of such Member, shall be free to effect such acquisition or investment at any time thereafter, and, so long as such acquisition or investment does not materially and adversely affect the Company, the Company will make its personnel and other resources available, on commercially reasonable terms, to assist the Member or its Affiliates in such acquisition or investment. This Section 8.4(b) shall not apply to, and no Facility Investment Offer shall be required in connection with, (i) the acquisition by a Member or its Affiliate of an equity interest that constitutes less than 5% o of the outstanding equity of, any Person; (ii) any acquisition or investment by a Member or its Affiliate in a Person that derives less than a majority of its net income from a Facility or Facilities; (iii) any acquisition or investment in a Member or any Affiliate of a Member by, or any merger, consolidation, or statutory share exchange by a Member or any Affiliate with, any Person that, at the time of such acquisition or investment, owns or has an equity interest in another Facility so long as the primary purpose for such acquisition or investment is not the acquisition or investment by the Member or its Affiliate in such Facility; or (iv) any joint venture (whether by contract or through the creation of a partnership, limited liability company or similar vehicle) with any Person that, at the time of creation of such joint venture, owns or has an equity interest in a Facility so long as the primary purpose for the creation of such joint venture is not the acquisition or investment by the Member or its Affiliate in such Facility.

Section 8.5 Indemnity of Members. Employees and Other Agent.

(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 Management Committee 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 Management Committee; 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, 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.

Section 8.7 Business Plan.

(a) The Members shall agree on a business plan for the Company (the "Initial Business Plan"), covering the operations of the Company and the Project Partnerships for the period from the date of this Agreement through December 31, 2001. The Initial Business Plan shall include a detailed budget for the Company and each Project Partnership prepared in accordance with customary practices for Facilities similar to those run by the Project Partnerships, and shall show (i) assumptions and projections of revenues and expenses for the Company and each respective Project Partnership by category and by month during such time period, (ii) known Maintenance Capital Expenditures to be incurred during such time period and (iii) the amount of working capital to be spent and retained by the Company during such time period. If the Members have been unable to agree upon and approve the Initial Business Plan prior to the Effective Date, then a Dispute shall be deemed to have occurred for purposes of Section 14.1. During any period of Dispute with respect to the Initial Business Plan, the business plan for the Company and the Project Partnerships in effect at the Effective Date shall be extended to the extent necessary to continue the short-term operation of the Company and the Project Partnerships.

(b) At least 45 days prior to the commencement of each calendar year, the Management Committee shall diligently and in good faith seek to approve an annual business plan for such calendar year (each, an "Annual Business Plan") prepared in a manner similar to the preparation of the Initial Business Plan (including, without limitation, detail on Maintenance Capital Expenditures to be incurred within one year of approval of such Annual Business Plan). If the Management Committee has been unable to agree upon and approve the Annual Business Plan for a calendar year prior to the commencement thereof, the Management Committee shall diligently and in good faith seek to approve an amended Annual Business Plan for the remainder of such year, but if no such Annual Business Plan is approved by January 31 of such year then a Dispute shall be deemed to have occurred for purposes of Section 14.1; provided, however, that no arbitrator of any such Dispute shall be permitted to make any determination with respect to, require any Member to make, an Additional Capital Contribution.

During any period of Dispute with respect to any Annual Business Plan (and any period of a calendar year for which an Annual Business Plan has not been approved by the Management Committee), the Annual Business Plan then in effect shall remain in effect and be extended to the extent necessary to continue the short-term operation of the Company and the Project Partnerships.

(a) None of UAE Holdings, UAE, UAE RF, Duke RF, Duke Capital Corporation, 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.

RF or any other Member or any Subsidiary of such Member will consummate any Transfer if based on the information received by UAE RF, Duke RF or such other Member, set forth above, such Transfer would result in an Adverse QF Event, or if UAE RF, Duke RF 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.

ARTICLE XI

TRANSFERS; ADJUSTMENT OF INITIAL OWNERSHIP PERCENTAGES

Section 11.1 Restrictions on Transfers.

(a) Subject to Section 11.2 and subsection (c) of this Section 11.1, a Member may (i) transfer, sell, assign, pledge, encumber or otherwise directly dispose of all of any portion of its Membership Interest, or (ii) by merger or other business combination involving such Member or a company directly or indirectly owning equity interests in such Member, cause a change in the ownership of, all or, any portion of its 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. The transferring Member and the transferee shall execute and acknowledge any and all such instruments as the Company may reasonably request to effectuate such Transfer, in each case in form and substance reasonably satisfactory to the Company. 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 the Transaction Documents, except as permitted thereunder.

Section 11.2 Rights of First Offer.

(a) Except as provided in Section 11.2(b), in the event that a Member or any of its Affiliates desires to transfer, sell, assign, pledge, encumber, or otherwise directly dispose of all or any portion of its Membership Interest than a Preferred Interest (an "Assignment") to any Person (other than an Affiliate of such Member), such Member (the "Assigning Member") shall first provide to each other Member and to the Company a written notice (a "First Offer Notice") that describes the Membership Interest the Assigning Member proposes to Assign, the purchase price or other consideration for which the Assigning Member proposes to Assign such Membership Interest, and the material terms and conditions upon which such Assignment is to take place. For a period of 60 days (or such longer period necessary to determine Fair Market Value) after delivery of the First Offer Notice, the Members other^- than the Assigning Member shall have the right and option (a "First Offer Right"), by giving written notice of the exercise of such right and option to the Assigning Member, all other Members (who are not Affiliates of the Assigning Member), and the Company, to purchase all, but not less than all, of the Membership Interest described in the First Offer Notice, for the same or a higher price and upon the same terms and conditions set forth in the First Offer Notice. The First Offer Right of each Member, other than the Assigning Member, shall be exercisable for a portion of the Membership Interest described in the First Offer Notice, such portion being the percentage of such Membership Interest that represents the Ownership Percentage of such Member as a percentage of the total Ownership Percentages of all Members (excluding the Ownership Percentage that is owned by the Assigning Member and its Affiliates), or such other percentage as all Members other than the Assigning Member and its Affiliates shall agree. If any Member fails to elect to exercise, or elects not to exercise, its First Offer Right prior to the end of the First Offer Period, such Member's First Offer Right may be exercised by the electing Members in proportion to their respective Ownership Percentages (excluding the Ownership Percentages of the Assigning Member and its Affiliates and of such non-electing Members). To the extent that any Assigning Member proposes in a First Offer Notice to accept consideration other than cash for a Membership Interest, the other Members may exercise their First Offer Rights by agreeing to pay such other consideration or to pay cash to the Assigning Member in an amount equal to the Fair Market Value of the consideration described in the First Offer Notice (or such higher price), and to the extent that the Assigning Member is proposing to Assign other assets in addition to a Membership Interest, the minimum purchase price for such Membership Interest shall equal the Fair Market Value thereof (it being understood that for purposes of this sentence the Assigning Member shall be considered the seller and that the other Members exercising their options to purchase their proportionate shares of the Membership Interest proposed to be Assigned shall be considered the buyers, in each case within the meaning of "Fair Market Value" as defined herein). If, prior to the end of the First Offer Period, the other Members have provided notice of their elections to acquire the entire Membership Interest that is the subject of the First Offer Notice, then such Members shall be obligated to acquire such Membership Interest on the terms described above no later than 90 days after the end of the First Offer Period, and the closings of all such sales to other Members shall be conducted simultaneously at the offices of the Company. If any Member fails to make payment of its purchase price or otherwise fails to perform its agreement to acquire a portion of the Membership Interest that is the subject of the First Offer Notice, then the Assigning Member may, in its sole discretion, (i) sell to such performing Members, in proportion to their Ownership Percentages (excluding the Ownership Percentages of the Assigning Member, all non-electing Members, and such non-performing Member), to the extent such performing Members agree, the Ownership Percentage that such non-performing Member has elected to purchase, or, if such performing Members do not agree, (ii) complete the sale of a portion or portions of such Membership Interest to other Members pursuant to their elections and seek such damages or equitable relief as maybe available at law or equity from such non-performing Member. In addition, if performing Members are unwilling to purchase the entire offered Membership Interest, the Assigning Member may treat either the entire Membership Interest that is the subject of the First Offer Notice or such portion thereof as the non-performing Member had elected to purchase as not subscribed pursuant to the First Offer, in

which case such Membership Interest or portion thereof (if the remaining amount is being sold to the performing Members) may be Assigned as set forth below. If, prior to the end of the First Offer Period, the Members other than the Assigning Member have not provided written notice of elections to purchase all of the Membership Interest described in the First Offer Notice, then the Assigning Member may, subject to Section 11.1, at any time during a period of 180 days after the end of the First Offer Period, Assign all, but not less than all, of the Membership Interest described in the First Offer Notice to any Person for a price and upon terms and conditions at least as favorable to the Assigning Member as those described in the First Offer Notice. If a binding agreement to complete such Assignment is not signed within such 180-day period, then such Membership Interest shall again become subject to the provisions of this Section 11.2. Notwithstanding the foregoing provisions of this Section 11.2(a), a Member may pledge or grant a security interest in all or a portion of its Membership Interest to a third party non-Affiliate in connection with a bona fide financing (or to a third party non-Affiliate in connection with one or more bona fide refinancings thereof); provided, however, that any subsequent Transfer of a Membership Interest so pledged or in which a security interest is so granted, whether pursuant to a foreclosure or otherwise, shall constitute an Assignment and give rise to a First Offer Right.

(b) In the event any Member is subject to Regulatory Restrictions at the time an Assigning Member provides a First Offer Notice, such Member shall be permitted to assign its rights and remedies under Section 11.2(a) to any other Person in order to comply with such Regulatory Restrictions; provided, however, that the exercise of such rights by the assignee will not cause an Adverse QF Event or an Adverse PUHCA Event for the Company or any Member.

(c) Notwithstanding the provisions of Section 11.2(a) (but subject to Section 11.1), at any time any Member may Assign all or any portion of its Membership Interest to an Affiliate of such Member or to Duke RF or UAE RF without complying with the provisions of Section 11.2(a); provided, however, that any such Assignment to an Affiliate does not result in an Adverse PUHCA Event or an Adverse QF Event. Notice of any Assignment permitted under this Section 11.2(c) shall be given by the Member effecting the Assignment to each other Member at least five Business Days prior to such Assignment. This Section 11.2 shall not apply to any transaction other than an Assignment, and in particular (but without limitation) shall not apply to the sale of any Member (or any company or other entity directly or indirectly owning interests in such Member) or to the creation by any Member of a Subsidiary to which such Member Assigns or contributes all or any portion of a Membership Interest.

Section 11.3 Purchase Option Upon Withdrawal. Involuntary Transfer or Breach.

(a) Upon the occurrence of any of the following events ("Defaults") concerning any Member, the other Members shall have the right to purchase the entire Membership Interest held by such Member at Fair Market Value and on the terms and conditions set forth in this Section 11.3:

(i) the filing of a petition by a Member for relief as a debtor or bankrupt under the U.S. Bankruptcy Code or any similar federal or state law affording debtor relief proceedings; the adjudication of insolvency of a Member as finally determined by a court proceeding or the filing by or on behalf of a Member to accomplish the- same or for the appointment of a receiver, custodian, assignee or trustee for the benefit of creditors of a Member;

(ii) the commencement of any proceedings relating to a Member by a third party under the U.S. Bankruptcy Code or similar federal or state law or other reorganization, arrangement, insolvency, adjustment of debt or liquidation law; the allowance of a Member's Membership Interest (or portion thereof) to become subject to attachment, garnishment, charging order, or similar charge unless any such preceding enumerated event is susceptible to cure and is cured within 90 days;

(iii) any withdrawal or attempted withdrawal of a Member other than as a result of a transfer of such Member's Membership Interest in accordance with this Article XI; or

(iv) the dissolution or termination of any Member that is a partnership or limited liability company; the liquidation of any Member that is a corporation; and the death or adjudication of incompetency of any individual Member.

(b) Any Member whose Membership Interest is subject to the purchase rights created by this Section 11.3 is referred to as the "Defaulting Member." Any Defaulting Member shall have the obligation to give notice to the other Members and the Company of any event triggering purchase rights under this Section 11.3.

(c) The non-defaulting Members' collective purchase rights under this Section 11.3 shall be allocated to the non-defaulting members on a pro rata basis in accordance with the Ownership Percentages of the non-defaulting Members electing to exercise such rights or as they otherwise agree. The non-defaulting Members' rights to purchase the Defaulting Member's interest pursuant to this Section 11.3 may be exercised by delivery of written notice to the Defaulting Member no later than 60 days after the last to occur of (i) the occurrence of the event giving rise to the purchase right under this Section 11.3 and (ii) actual receipt by the nondefaulting Members and the Company of written notice of the occurrence of such event. Upon delivery of such notice to purchase, the purchasing Member(s) shall have the right to purchase the Defaulting Member's Membership Interest, and the Defaulting Member shall be required to sell such interest for Fair Market Value.

(d) The Company may purchase the Defaulting Member's Membership Interest if it is not purchased by the non-defaulting Members by delivering written notice to the Defaulting Member within 5 days after the expiration of all time periods referenced in subsection (c). If the non-defaulting Members and the Company do not exercise their purchase rights pursuant to this Section 11.3, the Defaulting Partner's Partnership Interest shall be and become the interest of an assignee as set forth in Section 11.4.

(e) Unless otherwise agreed, the closing of the purchase of any Membership Interest under this Section 11.3 shall occur within 90 days after all notices are delivered to the Defaulting Member under subsections (c) and (d). The Purchase Price shall be payable in the full amount thereof in cash at closing. The Purchase Price shall be in full and complete satisfaction of the Defaulting Member's Membership Interest (or portion thereof purchased) and shall be binding upon the Defaulting Member and its respective successors and assigns.
