                  (a)      that Member is duly incorporated, organized or formed
         (as applicable), validly existing, and (if applicable) in good standing
         under the Law of the jurisdiction of its incorporation, organization or

         Agreement and the other documents contemplated herein, and they

         limited by bankruptcy, insolvency or similar Laws of general
         application and by the effect of general principles of equity,
         regardless of whether considered at law or in equity); and

                  (c)      that Member's authorization, execution, delivery, and
         performance of this Agreement does not and will not (i) conflict with,
         or result in a breach, default or violation of, (A) the organizational
         documents of such Member, (B) any contract or agreement to which that
         Member is a party or is otherwise subject, or (C) any Law, order,

         3.03     DISPOSITIONS AND ENCUMBRANCES OF MEMBERSHIP INTERESTS.

                  (a)      GENERAL RESTRICTION. A Member may not Dispose of or
         Encumber all or any portion of its Membership Interest except in strict
         accordance with this Section 3.03. (References in this Section 3.03 to
         Dispositions or Encumbrances of a "Membership Interest" shall also
         refer to Dispositions or Encumbrances of a portion of a Membership
         Interest.) Any attempted Disposition or Encumbrance of a Membership
         Interest, other than in strict accordance with this Section 3.03, shall
         be, and is hereby declared, null and void ab initio. The Members agree
         that a breach of the provisions of this Section 3.03 may cause
         irreparable injury to the Company and to the other Members for which
         monetary damages (or other remedy at law) are inadequate in view of (i)
         the complexities and uncertainties in measuring the actual damages that
         would be sustained by reason of the failure of a Member to comply with
         such provision and (ii) the uniqueness of the Company business and the
         relationship among the Members. Accordingly, the Members agree that the
         provisions of this Section 3.03 may be enforced by specific
         performance.

                  (b)      DISPOSITIONS OF MEMBERSHIP INTERESTS.

                           (i)      GENERAL RESTRICTION. A Member may not

                                    (A)      such Member must receive the
                           unanimous consent of the non- Disposing Members,
                           which consent shall not be unreasonably withheld by
                           each of such other Members; provided, however, that
                           such consent need not be obtained if (I) the proposed
                           Assignee is a Affiliate of the Disposing Member and
                           (II) such proposed Assignee demonstrates to the
                           reasonable satisfaction of the other Members that it
                           has the ability to meet the financial and contractual
                           commitments and other obligations of the Disposing
                           Member; and

                                    (B)      such Member must comply with the
                           requirements of Section 3.03(b)(iii) and, if the
                           Assignee is to be admitted as a Member, Section
                           3.03(b)(ii).

                           (ii)     ADMISSION OF ASSIGNEE AS A MEMBER. An
                  Assignee has the right to be admitted to the Company as a
                  Member, with the Membership Interest (and attendant Sharing
                  Ratio) so transferred to such Assignee, only if (A) the
                  Disposing Member making the Disposition has granted the
                  Assignee either (I) the Disposing Member's entire Membership
                  Interest or (II) the express right to be so admitted; and (B)
                  such Disposition is effected in strict compliance with this

                  Sections 3.03(b)(i) and 3.03(b)(ii), any Disposition of a
                  Membership

                                       7


                  Interest and any admission of an Assignee as a Member shall
                  also be subject to the following requirements, and such
                  Disposition (and admission, if applicable) shall not be
                  effective unless such requirements are complied with;
                  provided, however, that the Management Committee, in its sole
                  and absolute discretion, may waive any of the following
                  requirements:

                                    (A)      DISPOSITION DOCUMENTS. The

                  (c)      ENCUMBRANCES OF MEMBERSHIP INTEREST. A Member may
         Encumber its Membership Interest if (i) the instrument creating such
         Encumbrance provides that any foreclosure of such Encumbrance (or
         Disposition in lieu of such foreclosure) must comply with the
         requirements of Section 3.03(b), and (ii) any such Encumbrance is not
         prohibited by the Loan Documents.

                  (d)      RIGHT OF FIRST REFUSAL. Except as otherwise expressly
         permitted by this Agreement, this Section 3.03(d) shall apply to any
         proposed voluntary Disposition of a Membership Interest to any
         purchaser (other than a majority owned Affiliate of the disposing
         party) for consideration in the form of cash or promissory notes or
         other obligations to pay sums certain. The Member proposing to make
         such a Distribution shall provide written notice (a "Disposition
         Notice") to the remaining Members at least 90 days prior to the
         proposed Disposition. The Disposition Notice must set forth the
         identity of the proposed transferee, the sale price, and all other
         material terms and conditions of the proposed Disposition. In the Case
         of a Change of member Control, the Disposition notice must set forth
         the portion, if less than 100%, of the total purchase price that is
         applicable to such Member's Membership Interest. Upon receipt of a
         Disposition Notice, the remaining Members shall have the option for a
         period of 30 days to purchase all, but not less than all, of such
         Membership Interest. Such Membership Interest shall be allocated to the
         Members exercising their option under this Section 3.03(d) pro rata in
         accordance with their Membership Interests. The purchase pursuant to
         the exercise of this option shall be at the price and pursuant to the
         terms and conditions of the proposed Disposition. If no Member
         exercises such option, the Member proposing such Disposition shall be
         free, for a period of 60 days after the expiration of the remaining
         Members' options, to Dispose of the Membership Interests that were the
         subject of the Disposition Notice, but only to the party, and for the
         price and on the terms and conditions, set forth in the Disposition
         Notice. If the proposed disposition does not occur within 60 days after
         the expiration of the remaining Members' options, the Membership
         Interest may not be Disposed of pursuant to this section 30.0(d) unless
         the Member again complies with the terms of this Agreement.

                  (e)      RIGHTS IN MEMBERSHIP INTERESTS PLEDGED AS COLLATERAL.
         Any other provision of this Agreement to the contrary notwithstanding,
         by executing and delivering this Agreement, each Member shall be deemed
         to have consented to (i) the pledge, assignment, hypothecation and
         transfer to any creditor of the Company or NE Genco or its agents,
         successors or assigns of, and the grant to such creditor or other
         Person of a lien on and security interest in, as security for the
         indebtedness of the Company or NE Genco to such creditor, all of such
         Member's right, title and interest in, to and under its Membership
         Interest and any other collateral securing such indebtedness, (ii) the
         exercise by any such creditor or other Person of the rights and
         remedies under any security document related to such collateral,
         including, without limitation, the right to exercise the voting and
         consensual rights and other powers of each Member to the extent
         provided in any such security document, and (ii) the right to foreclose
         upon or exercise a power of sale with respect to the Membership
         Interest of each Member and any other collateral subject to such
         security documents and to cause the agent or designee of such creditor
         or any third party purchaser of such Membership Interest to become an
         additional or substitute Member, and (c) all other provisions of the
         loan and security documents relating to such indebtedness or
         collateral, the issuance of new or substituted Membership Interests, or
         the ownership of Membership Interests.

         3.04     CREATION OF ADDITIONAL MEMBERSHIP INTEREST. Provided that the
same is not prohibited by the Loan Documents, additional Membership Interests
may be created and issued to existing Members or to other Persons, and such
other Persons may be admitted to the Company as Members, with the unanimous
consent of the existing Members, on such terms and conditions as the existing
Members may unanimously determine at the time of admission. The terms of
admission or issuance must specify the Sharing Ratios applicable thereto and may
provide for the creation of different classes or groups of Members having
different rights, powers, and duties. The Management Committee may reflect the
creation of any new class or group in an amendment to this Agreement indicating
the different rights, powers, and duties. Any such admission is effective only
after the new Member has executed and delivered to the Members an instrument
containing the notice address of the new Member, the Assignee's ratification of
this Agreement and agreement to be bound by it, and its confirmation that the
representations and warranties in Section 3.02 are true and correct with respect
to it. The provisions of this Section 3.04 shall not apply to Dispositions of
Membership Interests or admissions of Assignees in connection therewith, such
matters being governed by Section 3.03.

         3.5      ACCESS TO INFORMATION. Each Member shall be entitled to
receive any information that it may request concerning the Company; provided,
however, that this Section 3.05 shall not obligate the Company or the Management
Committee to create any information that does not already exist at the time of
such request (other than to convert existing information from one medium to
another, such as providing a printout of information that is stored in a
computer database). Each Member shall also have the right, upon reasonable
notice, and at all reasonable times during usual business hours to inspect the
properties of the Company and to audit, examine and make copies of the books of
account and other records of the Company. Such right may be exercised through
any agent or employee of such Member designated in writing by it or by an
independent public accountant, engineer, attorney or other consultant so
designated. The Member making the request shall bear all costs and expenses
incurred in any inspection, examination or audit made on such Member's behalf.

to the provisions of Section 3.06.

                           (ii)     disclosures and uses that are approved by
                  the Management Committee;

                           (iii)    disclosures to an Affiliate of such Member
                  on a "need to know" basis in connection with the Company, if
                  such Affiliate has agreed to abide by the terms of this
                  Section 3.06;

                           (iv)     disclosures to a Person that is not a Member
                  or an Affiliate of a Member, if such Person has been retained
                  to provide services by the Member in connection with the

                           (v)      disclosures to lenders, potential lenders or
                  other Persons providing financing to the Company and potential
                  purchasers of equity interests in the Company, if such Persons
                  have agreed to abide by the terms of this Section 3.06;

                           (vi)     disclosures to any independent system
                  operator or its consultants and representatives in connection
                  with the Acquisitions or the conduct of the businesses of the

                           (viii)   disclosures that a Member is legally

                  documents, subpoena, civil investigative demand, order of a
                  court of competent jurisdiction, or similar process, or
                  otherwise by Law or securities exchange requirements;
                  provided, however, that, prior to any such disclosure, such
                  Member shall, to the extent legally permissible:

                                    (A)      provide the Management Committee
                           with prompt notice of such requirements so that one
                           or more of the Members may seek a protective order or
                           other appropriate remedy or waive compliance with the
                           terms of this Section 3.06(b)(vii);

                                    (B)      consult with the Management
                           Committee on the advisability of taking steps to
                           resist or narrow such disclosure; and

                                       10


                                    (C)      cooperate with the Management
                           Committee and with the other Members in any attempt
                           one or more of them may make to obtain a protective
                           order or other appropriate remedy or assurance that
                           confidential treatment will be afforded the
                           Confidential Information; and in the event such
                           protective order or other remedy is not obtained, or
                           the other Members waive compliance with the
                           provisions hereof, such Member agrees (I) to furnish
                           only that portion of the Confidential Information
                           that the other Members are advised by counsel to the
                           disclosing Member is legally required and (II) to
                           exercise all reasonable efforts to obtain assurance
                           that confidential treatment will be accorded such
                           Confidential Information.

                  (c)      Each Member shall take such precautionary measures as
         may be required to ensure (and such Member shall be responsible for)
         compliance with this Section 3.06 by any of its Affiliates, and its and
         their directors, officers, employees and agents, and other Persons to
         which it may disclose Confidential Information in accordance with this
         Section 3.06.

                  (d)      A Terminated Member shall promptly destroy (and
         provide a certificate of destruction to the Company with respect to) or
         return to the Company, as directed by the Management Committee, all
         Confidential Information in its possession. Notwithstanding the
         immediately-preceding sentence, a Terminated Member may, subject to the
         other provisions of this Section 3.06, retain and use Confidential
         Information for the limited purpose of preparing such Terminated
         Member's tax returns and defending audits, investigations and
         proceedings relating thereto.

                  (e)      The Members agree that no adequate remedy at law
         exists for a breach or threatened breach of any of the provisions of
         this Section 3.06, the continuation of which unremedied will cause the
         Company and the other Members to suffer irreparable harm. Accordingly,
         the Members agree that the Company and the other Members shall be
         entitled, in addition to other remedies that may be available to them,
         to immediate injunctive relief from any breach of any of the provisions
         of this Section 3.06 and to specific performance of their rights
         hereunder, as well as to any other remedies available at law or in
         equity.

                  (f)      The obligations of the Members under this Section
         3.06 shall terminate on the third anniversary of the end of the Term.

         3.07     LIABILITY TO THIRD PARTIES. No Member shall be liable for the
debts, obligations or liabilities of the Company.

         3.08     WITHDRAWAL. A Member may not withdraw or resign from the
Company except as permitted by this Agreement.

Sharing Ratio of all monies that in the unanimous judgment of the Management
Committee are necessary to enable the Company to acquire the Projects and to
cause the assets of the Operating Entities to be properly operated and
maintained and to pay and perform their respective costs, expenses, obligations
and liabilities. The Management Committee shall notify each Member of the need
for Capital Contributions pursuant to this Section 4.02 when appropriate, which
notice must include a statement in reasonable detail of the proposed uses of the

Business Day following each Member's receipt of its notice) before which the

         4.03     FAILURE TO CONTRIBUTE.

                  (a)      If a Member does not contribute, within 10 Days of
         the date required, all or any portion of a Capital Contribution that
         Member is required to make as provided in this Agreement, the other
         Members may cause the Company to exercise, on notice to that Member
         (the "Non-Contributing Member"), one or more of the following remedies:

                           (i)      taking such action (including court
                  proceedings) as the other Members may deem appropriate to
                  obtain payment by the Non-Contributing Member of the portion
                  of the Non-Contributing Member's Capital Contribution that is
                  in default, together with interest thereon at the Default Rate
                  from the date that the Capital Contribution was due until the
                  date that it is made, all at the cost and expense of the
                  Non-Contributing Member;

                           (ii)     permitting the other Members in proportion
                  to their Sharing Ratios or in such other percentages as they
                  may agree (the "Lending Member, " whether one or more), to
                  advance the portion of the Non-Contributing Member's Capital
                  Contribution that is in default, with the following results:

                                    (A)      the sum advanced constitutes a loan
                           from the Lending Member to the Non-Contributing
                           Member and a Capital Contribution of that sum to the
                           Company by the Non-Contributing Member pursuant to
                           the applicable provisions of this Agreement,

                                    (B)      the principal balance of the loan
                           and all accrued unpaid interest thereon is due and
                           payable in whole on the tenth Day after written
                           demand therefor by the Lending Member to the
                           Non-Contributing Member,

                                    (C)      the amount lent bears interest at
                           the Default Rate from the Day that the advance is
                           deemed made until the date that the loan, together
                           with all interest accrued on it, is repaid to the
                           Lending Member,

                                    (D)      all distributions from the Company
                           that otherwise would be made to the Non-Contributing
                           Member (whether before or after dissolution of the
                           Company) instead shall be paid to the Lending Member
                           until the loan and all interest accrued on it have
                           been paid in full to the Lending Member (with
                           payments being applied first to accrued and unpaid
                           interest and then to principal),

                                    (E)      the payment of the loan and
                           interest accrued on it is secured by a security
                           interest in the Non-Contributing Member's Membership
                           Interest, as more fully set forth in Section 4.03(b),
                           and

                                    (F)      the Lending Member has the right,
                           in addition to the other rights and remedies granted
                           to it pursuant to this Agreement or available to it
                           at Law or in equity, to take any action (including
                           court proceedings) that the Lending Member may deem
                           appropriate to obtain payment by the Non-Contributing
                           Member of the loan and all accrued and unpaid
                           interest on it, at the cost and expense of the
                           Non-Contributing Member;

                           (iii)    exercising the rights of a secured party
                  under the Uniform Commercial Code of the State of Delaware, as
                  more fully set forth in Section 4.03(b); or

                           (iv)     exercising any other rights and remedies
                  available at Law or in equity.

In addition, the failure to make such contributions shall constitute a Default
by the Non-Contributing Member, and the other Members shall have the rights set
forth in Article 9 with respect to such Default.

                                       12


Account of the Disposing Member that is attributable to such Membership Interest

         5.01     DISTRIBUTIONS OR BILLINGS. Distributions to the Members shall
be made only to all simultaneously in proportion to their respective Sharing
Ratios (at the time the amounts of such distributions are determined) and in
such aggregate amounts and at such times as shall be determined by the
Management Committee and as are permitted by the Loan Documents. When so
permitted, the Management Committee shall endeavor to distribute to the Members,
on or before the end of each calendar quarter, or more often if approved by the
Management Committee, the estimated amount of any cash available for such
calendar quarter (net of any adjustments, if any, made to reflect the actual
cash available for the preceding calendar quarter). Any cash in excess of the
Working Capital Requirements shall be distributed to the Members based on their
respective Sharing Ratios.

         5.02     DISTRIBUTIONS ON DISSOLUTION AND WINDING UP. Upon the
dissolution and winding up of the Company, after adjusting the Capital Accounts

Members' positive Capital Account balances.

                  (a)      For purposes of maintaining the Capital Accounts
         pursuant to Section 4.06 and for income tax purposes, except as
         provided in Section 5.03(b), each item of income, gain, loss, deduction
         and credit of the Company shall be allocated to the Members in
         accordance with their Sharing Ratios.

                  (b)      For income tax purposes, income, gain, loss, and
         deduction with respect to property contributed to the Company by a
         Member or revalued pursuant to Treasury Regulation Section 1.704-
         1(b)(2)(iv)(f) shall be allocated among the Members in a manner that
         takes into account the variation between the adjusted tax basis of such
         property and its book value, as required by Section 704(c) of the Code
         and Treasury Regulation Section 1.704-l(b)(4)(i), using the remedial

Persons shown on the records of the Company to have been Members as of the last
calendar day of the period for which the allocation or distribution is to be
made. Notwithstanding the foregoing, if during any taxable year there is a
change in any Member's Sharing Ratio, the Members agree that their allocable
shares of such items for the taxable year shall be determined on any method
determined by the Management Committee to be permissible under Code Section 706
and the related Treasury Regulations to take account of the Members' varying
Sharing Ratios.

                                    ARTICLE 6
                                   MANAGEMENT

         6.01     MANAGEMENT BY MEMBERS. Except as described below in Sections
6.03 and 6.05, the management of the Company is fully vested in the Members,
acting exclusively in their membership capacities. To facilitate the orderly and
efficient management of the Company, the Members shall act (a) collectively as a
"committee of the whole" pursuant to Section 6.02 or (b) through the delegation
from time to time of certain responsibility and authority to particular Members
pursuant to Section 6.04. No Member has the right, power or authority to act for
or on behalf of the Company, to do any act that would be binding on the Company,
or to incur any expenditures on behalf of the Company, except in accordance with
the immediately preceding sentence. Decisions or actions taken in accordance
with the provisions of this Agreement shall constitute decisions or actions by
the Company and shall be binding on each Member, Representative, Officer and
employee of the Company.

         6.2      MANAGEMENT COMMITTEE. The Members shall act collectively
through meetings as a "committee of the whole," which is hereby named the
"Management Committee." The Management Committee shall conduct its affairs in
accordance with the following provisions and the other provisions of this
Agreement:

                  (a)      REPRESENTATIVES.

                           (i)      DESIGNATION. To facilitate the orderly and
                  efficient conduct of Management Committee meetings, each
                  Member shall notify the other Members, from time to time, of
                  the identity of two of its officers, employees or agents who
                  will represent it at such meetings (each a "Representative").
                  In addition, each Member may (but shall have no obligation to)
                  notify the other Members, from time to time, of the identity
                  of other officers, employees or agents who will represent it
                  at any meeting that the Member's Representatives are unable to
                  attend (each an "Alternate Representative"). (The term
                  "Representative" shall also refer to any Alternate
                  Representative that is actually performing the duties of the
                  applicable Representative.). The initial Representatives of
                  each Member are set forth on Exhibit A. A Member may designate
                  different Representatives or Alternate Representatives for any
                  meeting of the Management Committee by notifying each of the
                  other Members at least three Business Days prior to the
                  scheduled date for such meeting; provided, however, that if
                  giving such advance notice is not feasible, then such new
                  Representatives or Alternate Representatives shall present
                  written evidence of their authority at the commencement of
                  such meeting.

                                       15


                           (ii)     AUTHORITY. Each Representative shall have
                  the full authority to act on behalf of the Member that
                  designated such Representative; the action of a Representative
                  at a meeting (or through a written consent) of the Management
                  Committee shall bind the Member that designated such
                  Representative; and the other Members shall be entitled to
                  rely upon such action without further inquiry or investigation
                  as to the actual authority (or lack thereof) of such
                  Representative. In addition, the act of an Alternate
                  Representative shall be deemed the act of the Representative
                  for which such Alternate Representative is acting, without the
                  need to produce evidence of the absence or unavailability of
                  such Representative.

                           (iii)    DISCLAIMER OF DUTIES; INDEMNIFICATION. EACH
                  REPRESENTATIVE SHALL REPRESENT, AND OWE DUTIES TO, ONLY THE
                  MEMBER THAT DESIGNATED SUCH REPRESENTATIVE (THE NATURE AND
                  EXTENT OF SUCH DUTIES BEING AN INTERNAL CORPORATE AFFAIR OF
                  SUCH MEMBER), AND NOT TO THE COMPANY, ANY OTHER MEMBER OR
                  REPRESENTATIVE, OR ANY OFFICER OR EMPLOYEE OF THE COMPANY. THE
                  PROVISIONS OF SECTION 6.05 SHALL ALSO INURE TO THE BENEFIT OF
                  EACH MEMBER'S REPRESENTATIVES. THE COMPANY SHALL INDEMNIFY,
                  PROTECT, DEFEND, RELEASE AND HOLD HARMLESS EACH REPRESENTATIVE
                  FROM AND AGAINST ANY CLAIMS ASSERTED BY OR ON BEHALF OF ANY
                  PERSON (INCLUDING ANOTHER MEMBER), OTHER THAN THE MEMBER THAT
                  DESIGNATED SUCH REPRESENTATIVE, THAT ARISE OUT OF, RELATE TO
                  OR ARE OTHERWISE ATTRIBUTABLE TO, DIRECTLY OR INDIRECTLY, SUCH
                  REPRESENTATIVE'S SERVICE ON THE MANAGEMENT COMMITTEE, OTHER
                  THAN SUCH CLAIMS ARISING OUT OF THE FRAUD OR WILLFUL
                  MISCONDUCT OF SUCH REPRESENTATIVE.

                           (iv)     ATTENDANCE. Each Member shall use all
                  reasonable efforts to cause its Representatives or Alternate
                  Representatives to attend each meeting of the Management
                  Committee, unless its Representatives are unable to do so
                  because of a "force majeure" event or other event beyond his
                  reasonable control, in which event such Member shall use all
                  reasonable efforts to cause its Representatives or Alternate
                  Representatives to participate in the meeting by telephone
                  pursuant to Section 6.02(h).

                  (b)      CHAIRMAN AND SECRETARY. One of the Representatives
         will be designated as Chairman of the Management Committee, in
         accordance with this Section 6.02(b), to preside over meetings of the
         Management Committee. The Management Committee shall also designate a
         Secretary of the Management Committee, who need not be a
         Representative.

                  (c)      PROCEDURES. The Secretary of the Management Committee
         shall maintain written minutes of each of its meetings, which shall be
         submitted for approval no later than the next regularly-scheduled
         meeting. The Management Committee may adopt whatever rules and
         procedures relating to its activities as it may deem appropriate,
         provided that such rules and procedures shall not be inconsistent with
         or violate the provisions of this Agreement.

                  (d)      TIME AND PLACE OF MEETINGS. The Management Committee
         shall meet quarterly, subject to more or less frequent meetings upon
         approval of the Management Committee. Notice of, and an agenda for, all
         Management Committee meetings shall be provided by the Chairman to all
         Members at least ten Days prior to the date of each meeting, together
         with proposed minutes of the previous Management Committee meeting (if
         such minutes have not been previously ratified). Special meetings of
         the Management Committee may be called at such times, and in such
         manner, as any Member deems necessary. Any Member calling for any such
         special meeting shall notify the Chairman, who in turn shall notify all
         Members of the date and agenda for such meeting at least ten Days prior
         to the date of such meeting. Such ten-day period may be shortened by
         the Management Committee. All meetings of the Management Committee
         shall be held at a location designated by the Chairman. Attendance of a
         Member at a meeting of the Management Committee shall constitute a
         waiver of notice of such meeting, except where such Member attends the
         meeting for the express purpose of objecting to the transaction of any
         business on the ground that the meeting is not lawfully called or
         convened.

                                       16


                  (e)      QUORUM. The presence of one Representative designated
         by each Member shall constitute a quorum for the transaction of
         business at any meeting of the Management Committee.

                  (f)      VOTING. Except as provided otherwise in this
         Agreement, (i) voting at any meeting of the Management Committee shall
         be according to the Members' respective Sharing Ratios, and (ii) the
         affirmative vote of Members holding a majority of the Sharing Ratios
         shall constitute the act of the Management Committee.

                  (g)      ACTION BY WRITTEN CONSENT. Any action required or
         permitted to be taken at a meeting of the Management Committee may be
         taken without a meeting, without prior notice, and without a vote if a
         consent or consents in writing, setting forth the action so taken, is
         signed by Members that could have taken the action at a meeting of the
         Management Committee at which all Members entitled to vote on the
         action were represented and voted.

                  (h)      MEETINGS BY TELEPHONE. Members may participate in and
         hold such meeting by means of conference telephone, video conference or
         similar communications equipment by means of which all persons
         participating in the meeting can hear each other. Participation in such
         a meeting shall constitute presence in person at such meeting, except
         where a Member participates in the meeting for the express purpose of
         objecting to the transaction of any business on the ground that the
         meeting is not lawfully called or convened.

                  (i)      SUBCOMMITTEES. The Management Committee may create
         such subcommittees, delegate to such subcommittees such authority and
         responsibility, and rescind any such delegations, as it may deem
         appropriate.

                  (j)      OFFICERS. The Management Committee may designate one
         or more Persons to be Officers of the Company. Any Officers so
         designated shall have such titles and, subject to the other provisions
         of this Agreement, have such authority and perform such duties as the
         Management Committee may specifically delegate to them and shall serve
         at the pleasure of the Management Committee.

         6.03     DELEGATION TO PARTICULAR MEMBER. The Management Committee may
delegate to one or more Members such authority and duties as the Management
Committee may deem advisable. Decisions or actions taken by any such Member in
accordance with the provisions of this Agreement shall constitute decisions or
actions by the Company and shall be binding on each Member, Representative,
Officer and employee of the Company. Any delegation pursuant to this Section
6.03 may be revoked at any time by the Management Committee. With respect to
duties discharged hereunder by a Member (a) such Member may discharge such
duties through the personnel of a Affiliate of such Member, and (b) unless the
Members otherwise agree, the Company shall compensate such Member (or its
Affiliate, as applicable) for the performance of such duties in an amount equal
to the manhours expended by the personnel of such Member (or its Affiliate)
multiplied by the applicable rate(s) shown on Exhibit B (which rates each shall
escalate on the first day of each calendar year during the term hereof by an
amount which is 5% of the rate applicable during the prior calendar year), and
shall reimburse such Member for all out of pocket costs incurred by such Member
in discharging such duties. In addition, prior to performing any such duties,
the performing Member shall provide to the other Member for approval an estimate
of man-hours and types of personnel required to perform the delegated duties and
a schedule for the performance of the delegated duties and for other costs
associated therewith, and shall promptly inform the other Member of any variance
from the budget or schedule.

         6.04     AFFILIATE AGREEMENTS; CONFLICTS OF INTEREST. Subject to any
other agreement between the Members (and their respective Affiliates, as
applicable), a Member or an Affiliate of a Member may engage in and possess
interests in other business ventures of any and every type and description,
independently or with others, including ones in competition with the Company,
with no obligation to offer to the Company, any other Member or any Affiliate of
another Member the right to participate therein. Subject to, and in addition to,
Section 6.03(a), the Company may transact business with any Member or Affiliate
thereof, provided the terms of those transactions are approved by the Management
Committee or expressly contemplated by this Agreement. Without limiting the
generality of the foregoing, the Members recognize and agree that they and their
respective Affiliates currently engage in certain activities involving the
generation, transmission, distribution, marketing and trading of electricity

                                       17


and other energy products (including futures, options, swaps, exchanges of
future positions for physical deliveries and commodity trading), and the
gathering, processing, storage and transportation of such products, as well as
other commercial activities related to such products, and that these and other
activities by Members and their Affiliates may be made possible or more
profitable by reason of the Company's activities (herein referred to as "Outside
Activities"). The Members agree that (i) no Member or Affiliate of a Member
shall be restricted in its right to conduct, individually or jointly with
others, for its own account any Outside Activities, and (ii) no Member or its
Affiliates shall have any duty or obligation, express or implied, to account to,
or to share the results or profits of such Outside Activities with, the Company,
any other Member or any Affiliate of any other Member, by reason of such Outside
Activities.

         6.05     UNANIMOUS CONSENT REQUIRED FOR CERTAIN ACTION. Any other
provision of this Agreement to the contrary notwithstanding, the unanimous
consent of the Members, including at least one Independent Member, shall be
required to:

                  (a)      File a bankruptcy or insolvency petition or otherwise
         institute insolvency proceedings with respect to the Company, or take
         any action that would result in such an event occurring with respect to
         NE Genco.

                  (b)      Cause the dissolution, liquidation, consolidation,
         merger or sale of substantially all of the assets of the Company or NE
         Genco.

                  (c)      Cause or permit the Company to engage in any other
         activity other than those set forth in Section 2.04.

                  (d)      Amend this Agreement in any manner that would have a
         material adverse impact on any creditor of the Company.

         6.06     CERTAIN ACTIONS PROHIBITED. So long as the Company has any
indebtedness outstanding, (a) the Company shall not be dissolved, liquidated,
consolidated or merged with any other entity, nor shall this Agreement be
amended in any manner that would have a material adverse impact on the holders
of such indebtedness, and (b) notwithstanding the failure of the Members to
continue the existence of the Company as provided in Section 2.06 during such
period, no action shall be taken by the Company or any of the Members shall
cause any collateral for such indebtedness to be liquidated or that would
adversely affect the rights of the holders of such indebtedness or their agents
to exercise their rights under any security documents relating thereto or to
retain such collateral until such indebtedness is paid in full or otherwise
completely discharged.

         6.07     DISCLAIMER OF DUTIES AND LIABILITIES.

                  (a)      NO MEMBER SHALL OWE ANY DUTY (INCLUDING ANY FIDUCIARY
         DUTY) TO THE OTHER MEMBERS OR TO THE COMPANY, OTHER THAN THE DUTIES
         THAT ARE EXPRESSLY SET FORTH IN THIS AGREEMENT.

                  (b)      NO MEMBER SHALL BE LIABLE (WHETHER IN CONTRACT, TORT
         OR OTHERWISE) FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL
         DAMAGES).

                  (c)      THE OBLIGATIONS OF THE MEMBERS UNDER THIS AGREEMENT
         ARE OBLIGATIONS OF THE MEMBERS ONLY, AND NO RECOURSE SHALL BE AVAILABLE
         AGAINST ANY OFFICER, DIRECTOR OR AFFILIATE OF ANY MEMBER, EXCEPT AS
         PERMITTED UNDER APPLICABLE LAW.

         6.08     INDEMNIFICATION. Each Member shall indemnify, protect, defend,
release and hold harmless each other Member, and such other Member's
Representatives, Affiliates, and their respective directors, officers, employees
and agents from and against any Claims asserted by or on behalf of any Person
(including another Member) that arise out of, relate to or are otherwise
attributable to, directly or indirectly, a breach by the indemnifying Member of
this Agreement, or the negligence, gross negligence or willful misconduct of the
indemnifying Member in connection with the Project or this Agreement; provided,
however, that this Section 6.05

                                       18


shall not apply to any Claim or other matter for which a Member (or its
Representative) has no liability or duty, or is indemnified or released,
pursuant to Section 6.02(a)(iii), 6.07 or 6.08.

                                    ARTICLE 7
                                      TAXES

         7.01     TAX RETURNS. The Tax Matters Member shall prepare and timely
file (on behalf of the Company) all federal, state and local tax returns
required to be filed by the Company. Each Member shall furnish to the Tax
Matters Member all pertinent information in its possession relating to the
Company's operations that is necessary to enable the Company's tax returns to be
timely prepared and filed. The Company shall bear the costs of the preparation
and filing of its returns.

         7.02     TAX ELECTIONS. The Company shall make the following elections
on the appropriate tax returns:

                  (a)      to adopt as the Company's fiscal year the calendar
         year;

                  (b)      to adopt the accrual method of accounting;

                  (c)      if a distribution of the Company's property as
         described in Code Section 734 occurs or upon a transfer of Membership
         Interest as described in Code Section 743 occurs, on request by notice
         from any Member, to elect, pursuant to Code Section 754, to adjust the
         basis of the Company's properties;

                  (d)      to elect to amortize the organizational expenses of
         the Company ratably over a period of 60 months as permitted by Section
         709(b) of the Code; and

                  (e)      any other election the Management Committee may deem
         appropriate.

Neither the Company nor any Member shall make an election for the Company to be
excluded from the application of the provisions of subchapter K of chapter 1 of
subtitle A of the Code or any similar provisions of applicable state law and no
provision of this Agreement (including Section 2.07) shall be construed to
sanction or approve such an election.

         7.03     TAX MATTERS MEMBER.

                  (a)      NRG shall be the "tax matters partner" of the Company
         pursuant to Section 6231 (a)(7) of the Code (the "Tax Matters Member").
         At the request of each other Member, the Tax Matters Member shall take
         such action as may be necessary to cause, to the extent possible, such
         other Member to become a "notice partner" within the meaning of Section
         6223 of the Code. The Tax Matters Member shall inform each other Member
         of all significant matters that may come to its attention in its
         capacity as Tax Matters Member by giving notice thereof on or before
         the fifth Business Day after becoming aware thereof and, within that
         time, shall forward to each other Member copies of all significant
         written communications it may receive in that capacity.

                  (b)      The Tax Matters Member shall take no action without
         the authorization of the Management Committee, other than such action
         as may be required by Law. Any cost or expense incurred by the Tax
         Matters Member in connection with its duties, including the preparation
         for or pursuance of administrative or judicial proceedings, shall be
         paid by the Company.

                  (c)      The Tax Matters Member shall not enter into any
         extension of the period of limitations for making assessments on behalf
         of the Members without first obtaining the consent of the Management
         Committee. The Tax Matters Member shall not bind any Member to a
         settlement agreement without obtaining the consent of such Member. Any
         Member that enters into a settlement agreement with respect to any
         Company item (as described in Code Section 6231(a)(3)) shall notify the
         other Members of such settlement agreement and its terms within 90 Days
         from the date of the settlement.

                                       19


                  (d)      No Member shall file a request pursuant to Code
         Section 6227 for an administrative adjustment of Company items for any
         taxable year without first notifying the other Members. If the
         Management Committee consents to the requested adjustment, the Tax
         Matters Member shall file the request for the administrative adjustment
         on behalf of the Members. If such consent is not obtained within 30
         Days from such notice, or within the period required to timely file the
         request for administrative adjustment, if shorter, any Member,
         including the Tax Matters Member, may file a request for administrative
         adjustment on its own behalf. Any Member intending to file a petition
         under Code Sections 6226, 6228 or other Code Section with respect to
         any item involving the Company shall notify the other Members of such
         intention and the nature of the contemplated proceeding. In the case
         where the Tax Matters Member is the Member intending to file such
         petition on behalf of the Company, such notice shall be given within a
         reasonable period of time to allow the other Members to participate in
         the choosing of the forum in which such petition will be filed.

                  (e)      If any Member intends to file a notice of
         inconsistent treatment under Code Section 6222(b), such Member shall
         give reasonable notice under the circumstances to the other Members of
         such intent and the manner in which the Member's intended treatment of
         an item is (or may be) inconsistent with the treatment of that item by
         the other Members.

         records of the Company, supporting documentation of the transactions
         with respect to the conduct of the Company's business and minutes of
         the proceedings of its Members and the Management Committee, and any
         other books and records that are required to be maintained by
         applicable Law.

                  (b)      The books of account of the Company shall be (i)
         maintained on the basis of a fiscal year that is the calendar year,
         (ii) maintained on an accrual basis in accordance with generally
         accepted accounting principles, consistently applied, and (iii) audited
         by the Certified Public Accountants at the end of each calendar year.

         8.02     REPORTS.

                  (a)      With respect to each calendar year, the Management
         Committee shall prepare and deliver to each Member:

                  returns and such other accounting, tax information and
                  schedules as shall be necessary for the preparation by each
                  Member on or before July 15 following the end of each calendar
                  year of its income tax return with respect to such year.

                  (b)      Within 15 Business Days after the end of each
         calendar month, the Management Committee shall cause to be prepared and
         delivered to each Member, with an appropriate certificate of the Person
         authorized to prepare the same (provided that the Management Committee
         may change the financial statements required by this Section 8.02(b) to
         a quarterly basis or may make such other change therein as it may deem
         appropriate):

                  Member's Capital Account as of the end of such month and the
                  portion of the calendar year then ended; and

                           (iii)    A statement comparing the actual financial
                  status and results of the Company as of the end of or for such
                  month and the portion of the calendar year then ended with the
                  budgeted or forecasted status and results as of the end of or
                  for such respective periods.

                  (c)      The Management Committee shall also cause to be
         prepared and delivered to each Member such other reports, forecasts,
         studies, budgets and other information as the Management Committee may
         request from time to time.

         8.03     BANK ACCOUNTS. Funds of the Company shall be deposited in such
banks or other depositories as shall be designated from time to time by the
Management Committee. All withdrawals from any such depository shall be made
only as authorized by the Management Committee and shall be made only by check,
wire transfer, debit memorandum or other written instruction.

                                    ARTICLE 9
                                  BUYOUT OPTION

         9.01     BUYOUT EVENTS. This Article 9 shall apply to any of the
following events (each a "Buyout Event"):

                  (a)      a Member shall dissolve or become Bankrupt; or

                  (b)      a Member shall commit a Default.

In each case, the Member with respect to whom a Buyout Event has occurred is
referred to herein as the "Affected Member."

         9.02     PROCEDURE. If a Buyout Event occurs and is not cured within 30
Business Days of the Affected Member's receipt of notice thereof from another
Member (or such shorter period (not less than 10 Business Days) as may be
reasonable under the circumstances and set forth in such notice), then each of
the other Members shall have the option to acquire the Membership Interest of
the Affected Member (or to cause it to be acquired by a third party designated
by the other Members), in accordance with procedures that are substantively
equivalent to those set forth in Section 3.03(b)(iii) (and with the Members
exercising such preferential right also being referred to herein as "Purchasing
Members ").

         9.03     PURCHASE PRICE; TERMS AND METHOD OF PAYMENT. The purchase
price for a Membership Interest being purchased pursuant to this Article 9 (the
"Purchase Price") shall be determined in the following manner. The Affected
Member and the Purchasing Members shall attempt to agree upon the fair market
value of the applicable Membership Interest and the terms and method of payment
of such amount. If those Members do not reach such agreement on or before the
30th Day following the exercise of the option, any such Member, by notice to the
others, may require the determination of fair market value and the terms and
method of payment to be made by the Arbitrator pursuant to Article 10.

         9.04     CLOSING. If an option to purchase is exercised in accordance
with the other provisions of this Article 9, the closing of such purchase shall
occur on the 30th Day after the determination of the Fair Market Value pursuant
to Section 9.03 (or, if later, the fifth Business Day after the receipt of all
applicable regulatory and governmental approvals to the purchase), and shall be
conducted in a manner substantively equivalent to that set forth in Section
3.03.

         9.05     TERMINATED MEMBER. Upon the occurrence of a closing under
Section 9.04, the following provisions shall apply to the Affected Member (now a
"Terminated Member"):

                  (a)      The Terminated Member shall cease to be a Member
         immediately upon the occurrence of the closing.

                                       21


                  (b)      As the Terminated Member is no longer a Member, it
         will no longer be entitled to receive any distributions (including
         liquidating distributions) or allocations from the Company, and neither
         it nor its Representative shall be entitled to exercise any voting or
         consent rights or to receive any further information (or access to
         information) from the Company.

                  (c)      The Terminated Member must pay to the Company all
         amounts owed to it by such Member.

                  (d)      The Terminated Member shall remain obligated for all
         liabilities it may have under this Agreement or otherwise with respect
         to the Company that accrue prior to the closing.

                  (f)      The Sharing Ratio of the Terminated Member shall be
         allocated among the purchasing Members in the proportion of the total
         Purchase Price paid by each.

                                   ARTICLE 10
                               DISPUTE RESOLUTION

         10.01    DISPUTES. This Article 10 shall apply to any dispute arising
under or related to this Agreement (whether arising in contract, tort or
otherwise, and whether arising at law or in equity), including (a) any dispute
regarding the construction, interpretation, performance, validity or
enforceability of any provision of this Agreement or whether any Person is in
compliance with, or breach of, any provisions of this Agreement, and (b) the
applicability of this Article 10 to a particular dispute. Notwithstanding the
foregoing, this Article 10 shall not apply to any matters that, pursuant to the
provisions of this Agreement, are to be resolved by a vote of the Members
(including through the Management Committee); provided, however, that if a vote,
approval, consent, determination or other decision must, under the terms of this
Agreement, be made (or withheld) in accordance with a standard other than Sole
Discretion (such as a reasonableness standard), then the issue of whether such
standard has been satisfied may be a dispute to which this Article 10 applies.
Any dispute to which this Article 10 applies is referred to herein as a
"Dispute." With respect to a particular Dispute, each Member that is a party to
such Dispute is referred to herein as a "Disputing Member." The provisions of
this Article 10 shall be the exclusive method of resolving Disputes.

         10.02    NEGOTIATION TO RESOLVE DISPUTES. If a Dispute arises, either
Disputing Member may initiate the dispute-resolution procedures of this Article
10 by delivering a notice (a "Dispute Notice") to the other Disputing Members.
Within 10 Days of delivery of a Dispute Notice, each Disputing Member shall
designate a representative, and such representatives shall promptly meet
(whether by phone or in person) in a good faith attempt to resolve the Dispute.
If such representatives can resolve the Dispute, such resolution shall be
reported in writing and shall be binding upon the Disputing Members. If such
representatives are unable to resolve the Dispute within 30 Days following the
delivery of the Dispute Notice (or such other period as such representatives may
agree), or if a Disputing Member fails to appoint a representative within 10
Days of delivery following the delivery of the Dispute Notice, then any
Disputing Member may take such Dispute to litigation.

                                   ARTICLE 11
                    DISSOLUTION, WINDING-UP AND TERMINATION

         11.01    DISSOLUTION. The Company shall dissolve and its affairs shall
be wound up on the first to occur of the following events (each a "Dissolution
Event"):

                  (a)      the unanimous consent of the Members; or

                  (b)      entry of a decree of judicial dissolution of the
         Company under Section 18-802 of the Act.

         11.02    WINDING-UP AND TERMINATION.

                  (a)      On the occurrence of a Dissolution Event, the
         Management Committee shall select one Member to act as liquidator. The
         liquidator shall proceed diligently to wind up the affairs of the
         Company

                                       22


         and make final distributions as provided herein and in the Act. The
         costs of winding up shall be borne as a Company expense. Until final
         distribution, the liquidator shall continue to operate the Company
         properties with all of the power and authority of the Members. The
         steps to be accomplished by the liquidator are as follows:

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

                           (ii)     the liquidator shall discharge from Company
                  funds all of the Indebtedness and other debts, liabilities and
                  obligations of the Company (including all expenses incurred in
                  winding up and any loans described in Section 4.03) or
                  otherwise make adequate provision for payment and discharge
                  thereof (including the establishment of a cash escrow fund for
                  contingent liabilities in such amount and for such term as the
                  liquidator may reasonably determine); and

                           (iii)    all remaining assets of the Company shall be
                  distributed to the Members as follows:

                                    (A)      the liquidator may sell any or all
                           Company property, including to Members, and any
                           resulting gain or loss from each sale shall be
                           computed and allocated to the Capital Accounts of the
                           Members in accordance with the provisions of Article
                           5;

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

                                    (C)      Company property (including cash)
                           shall be distributed among the Members in accordance
                           with Section 5.02; and those distributions shall be
                           made by the end of the taxable year of the Company
                           during which the liquidation of the Company occurs
                           (or, if later, 90 Days after the date of the
                           liquidation).

                  (b)      The distribution of cash or property to a Member in
         accordance with the provisions of this Section 11.02 constitutes a
         complete return to the Member of its Capital Contributions and a
         complete distribution to the Member of its Membership Interest and all
         the Company's property and constitutes a compromise to which all
         Members have consented pursuant to Section 18-502(b) of the Act. To the
         extent that a Member returns funds to the Company, it has no claim
         against any other Member for those funds.

         11.03    DEFICIT CAPITAL ACCOUNTS. No Member will be required to pay to
the Company, to any other Member or to any third party any deficit balance that
may exist from time to time in the Member's Capital Account.

         11.04    CERTIFICATE OF CANCELLATION. On completion of the distribution
of Company assets as provided herein, the Members (or such other Person or
Persons as the Act may require or permit) shall file a certificate of
cancellation with the Secretary of State of Delaware, cancel any other filings
made pursuant to Section 2.05, and take such other actions as may be necessary
to terminate the existence of the Company. Upon the filing of such certificate
of cancellation, the existence of the Company shall terminate (and the Term
shall end), except as may be otherwise provided by the Act or other applicable
Law.

                                   ARTICLE 12
                               GENERAL PROVISIONS

         12.01    OFFSET. Whenever the Company is to pay any sum to any Member,
any amounts that Member owes the Company may be deducted from that sum before
payment.

                                       23


         12.02    NOTICES. Except as expressly set forth to the contrary in this
Agreement, all notices, requests or consents provided for or permitted to be
given under this Agreement must be in writing and must be delivered to the
recipient in person, by courier or mail or by facsimile or other electronic
transmission. A notice, request or consent given under this Agreement is
effective on receipt by the Member to receive it; provided, however, that a
facsimile or other electronic transmission that is transmitted after the normal
business hours of the recipient shall be deemed effective on the next Business
Day. All notices, requests and consents to be sent to a Member must be sent to
or made at the addresses given for that Member on Exhibit A or in the instrument
described in Section 3.03(b)(iv)(A)(II) or 3.04, or such other address as that
Member may specify by notice to the other Members. Any notice, request or
consent to the Company must be given to all of the Members. Whenever any notice
is required to be given by Law, the Delaware Certificate or this Agreement, a
written waiver thereof, signed by the Person entitled to notice, whether before
or after the time stated therein, shall be deemed equivalent to the giving of
such notice.

         12.03    ENTIRE AGREEMENT; SUPERSEDING EFFECT. This Agreement
constitutes the entire agreement of the Members and their Affiliates relating to
the Company and the transactions contemplated hereby and supersedes all
provisions and concepts contained in all prior contracts or agreements between
the Members or any of their Affiliates with respect to the Company and the
transactions contemplated hereby, whether oral or written, except for the
Preliminary Agreement as specifically provided herein, and for liabilities
accrued under the Preliminary Agreement.

         12.04    PRESS RELEASES. Each Member agrees that it shall not (and
shall cause its Affiliates not to), without the other Members' consent, issue a
press release or have any contact with or respond to the news media with any
sensitive or Confidential Information, except as required by securities or
similar laws applicable to a Member and its Affiliates. Any press release by a
Member or its Affiliates with respect to any sensitive or Confidential
Information shall be subject to review and approval by the other Party, which
approval shall not be unreasonably withheld.

         12.05    EFFECT OF WAIVER OR CONSENT. Except as otherwise provided in
this Agreement, a waiver or consent, express or implied, to or of any breach or
default by any Member in the performance by that Member of its obligations with
respect to the Company is not a consent or waiver to or of any other breach or
default in the performance by that Member of the same or any other obligations
of that Member with respect to the Company. Except as otherwise provided in this
Agreement, failure on the part of a Member to complain of any act of any Member
or to declare any Member in default with respect to the Company, irrespective of
how long that failure continues, does not constitute a waiver by that Member of
its rights with respect to that default until the applicable
statute-of-limitations period has run.

         12.06    AMENDMENT OR RESTATEMENT. This Agreement or the Delaware
Certificate may be amended or restated only by a written instrument executed
(or, in the case of the Delaware Certificate, approved) by all of the Members.

         12.07    BINDING EFFECT. Subject to the restrictions on Dispositions
set forth in this Agreement, this Agreement is binding on and shall inure to the
benefit of the Members and their respective successors and permitted assigns.

         12.08    GOVERNING LAW; CONSTRUCTION. This Agreement is governed by and
shall be construed in accordance with the Law of the state of Delaware,
excluding any conflict-of-laws rule or principle that might refer the governance
or the construction of this agreement to the Law of another jurisdiction. In the
event of a direct conflict between the provisions of this Agreement and any
mandatory, non-waivable provision of the Act, such provision of the Act shall
control.
