                      MEMBERSHIP AND CAPITAL

     3.1  Members Initial Capital Contributions.  The sole initial Member of
the Company is NEI, which is admitted to the Company as a Member effective
upon its execution of this Agreement. The Capital Contribution of NEI has been
made by virtue of the conversion of its membership interest in AllEnergy
Marketing Company, L.L.C., a Massachusetts limited liability company merged
with and into the Company on the date hereof.
<PAGE>
     3.2  Maintenance of Capital Accounts.  A separate account (each a
"Capital Account") shall be established and maintained for each Member which
shall be increased by (a) such Member's Capital Contributions and (b) such
Member's share of the Net Profit of the Company, and shall be charged with (c)
Distributions to such Member and (d) such Member's share of the Net Losses of
the Company. It is the intention of the Members that the Capital Accounts be
maintained in accordance with the provisions of Section 704(b) of the Code and
the Regulations thereunder, that any liabilities be taken into account in
accordance with the provisions of Section 752 of the Code and the Regulations
thereunder, and that this Agreement be interpreted consistently therewith.

     3.3  Percentage Interests.  The percentage interest of each Member in
the profits of the Company (each a "Percentage Interest") shall initially be
as follows:

                           NEI     100%

The Percentage Interests of the Members shall be subject to adjustment as
provided in Sections 3.6 and 3.7.4.

     3.4  Additional Capital Contributions.

          3.4.1   Required Contributions.  The Required Members may from
     time to time determine that additional Capital Contributions are
     required by the Company. In such a case, each Member agrees that within
     not more than ten Business Days (or such longer period of time as the
     Required Members may determine) following the determination by the
     Required Members that additional Capital Contributions are necessary,
     which period may be extended by agreement of the Required Members, such
     Member will contribute to the Company (in cash unless otherwise
     determined (and agreed as to the nature and valuation) by the Required
     Members) as an additional Capital Contribution that percentage of the
     aggregate additional Capital Contributions required of all Members that
     is equal to its Percentage Interest.

          3.4.2   Funds Transfers.  Capital Contributions required by this
     Section 3.4 shall be made by wire transfer of immediately available
     funds to the Company' s account at such bank as the Company may from
     time to time designate in writing (or if property other than cash is to
     be contributed, in the manner specified by the Required Members).

          3.4.3   Voluntary Contributions.  Following the Effective Date, no
     Member shall be required or permitted to make any Capital Contributions
     to the Company except pursuant to this Section 3.4.

     3.5  Return of Capital Contributions.  No Member shall have the right
to demand a return of all or any part of its Capital Contributions, and any
return of the Capital Contributions of any Member shall be made solely from
the assets of the Company and only in accordance with the terms of this
Agreement. No interest shall be paid to any Member with respect to its Capital
Contributions.

     3.6  Additional Members; New Issuances; Classes of Members.  Except as
contemplated by Article 9, no new Members shall be admitted to the Company
without the consent of the Required Members. Upon the written consent of the
Required Members, the Company may issue Interests, which may represent
interests in both the capital and the profits of the Company or which may be
interests in only the future profits of the Company ("Profits Interests") to
Persons who are not yet Members, or may increase the Interest of an existing
Member, for such consideration (including but not limited to cash, other
property or the provision of services, whether future, current or past) and on
such terms as the Required Members shall determine. Upon the issuance of a new
Interest, or an increase in the Percentage Interest represented by an existing
Interest, the Percentage Interests of all existing Members shall be diluted
<PAGE>
ratably. Each Person that is to be issued an Interest shall deliver to the
Company, as a condition of its admission to the Company as a Member, such
documents of the type specified in Section 9.5.1(i) and (ii) as the Required
Members shall request. The Members shall constitute a single class of Members
for all purposes under the Act and this Agreement unless and to the extent
that this Agreement specifically provides for different classes or groups of
Members of the Company.

                            ARTICLE 4

                   STATUS AND RIGHTS OF MEMBERS

     4.1  Limited Liability.  Except as otherwise provided by the Act, the
debts, obligations and liabilities of the Company, whether arising in
contract, tort or otherwise, shall be solely the debts, obligations and
liabilities of the Company, and no Member nor any other Indemnified Person
shall be obligated personally for any such debt, obligation or liability of
the Company.  All Persons dealing with the Company shall look solely to the
assets of the Company for the payment of the debts, obligations or liabilities
of the Company.

     4.2  No Make Up.  In no event shall any Member be required to pay to
the Company, to any other Member or its Affiliate or to any third party, any
deficit balance that may exist from time to time in such Member's Capital
Account.

     4.3  Return of Distributions.  Except as otherwise expressly required
by law, a Member, in its capacity as such, shall have no liability either to
the Company or any of its creditors in excess of (a) the amount of its Capital
Contributions actually made, (b) its share of any assets and undistributed
profits of the Company, (c) its obligation to make Capital Contributions and
any other payments expressly provided for in this Agreement, and (d) to the
extent required by law, the amount of any Distributions wrongfully distributed
to it; provided, however, that, to the maximum extent permitted by applicable
law, the obligations of the Members under Section 3.4 shall be solely for the
benefit of the Company and not the creditors of the Company.  Except as
required by law or a court of competent jurisdiction, no Member shall be
obligated by this Agreement to return any Distribution to the Company or pay
the amount of any Distribution for the account of the Company or to any
creditor of the Company. However, if any court of competent jurisdiction holds
that, notwithstanding the provisions of this Agreement, any Member is
obligated to return or pay any part of any Distribution, the obligation shall
be that of such Member alone, and not of any other Member unless the court so
provides.  The amount of any Distribution returned to the Company by or on
behalf of a Member or paid by or on behalf of a Member for the account of the
Company or to a creditor of the Company shall be added to the account or
accounts from which it was subtracted when it was distributed to the Member.

     4.4  Specific Limitations.  No Member shall have the right or power to:
(a) withdraw or reduce its Capital Contribution except as a result of the
dissolution of the Company or as otherwise provided by law or in this
Agreement, (b) other than upon the Effective Date or with the approval of the
Required Members, make voluntary Capital Contributions or to contribute any
property to the Company other than cash, (c) bring an action for partition
against the Company or any Company assets, (d) cause the termination and
dissolution of the Company, except as set forth in this Agreement, or (e) upon
the distribution of its Capital Contribution require that property other than
cash be distributed in return for its Capital Contribution.  Each Member
hereby irrevocably waives any and all rights that it may have to maintain an
action for partition of any of the Company's property.  Except as otherwise
set forth in this Agreement, no Member shall have priority over any other
Member either as to the return of its Capital Contribution or as to Net
Profit, Net Loss, or Distributions; provided, that this provision shall not
apply to the repayment by the Company of loans (as distinguished from Capital
<PAGE>
Contributions) which a Member has made to the Company.  Other than upon the
termination and dissolution of the Company as provided by this Agreement,
there has been no time agreed upon when the Capital Contribution of any Member
will be returned.

     4.5  Hiring of Company Employees.

          4.5.1   Hiring of Company Employees.  During the Term, no Member
     nor any Affiliate of a Member shall hire, employ or otherwise retain the
     services of, including as an independent contractor, any person who is
     then serving, or who within the last year served, as either the chief
     executive officer or the chief operating officer of the Company, without
     the prior written consent of the other Members, which consent will not
     unreasonably be withheld.  In the event that any employee or former
     employee of the Company (including, with the consent of the other
     Members, the chief executive officer or chief operating officer of the
     Company, but not including any secretarial or clerical employee) is at
     any time hired, employed or otherwise retained to provide services by a
     Member or an Affiliate of a Member, such employee shall not (and the
     hiring Member or Affiliate shall not permit such employee to) for the
     one-year period commencing on the date on which he or she begins
     providing services to such Member or Affiliate of a Member, perform,
     engage in, participate in, direct, or otherwise consult or provide
     advice or information with respect to, any business activity that
     competes directly with any business activity engaged in by the Company.

          4.5.2   Severability.  If any of the restrictions set forth in
     this Section 4.5 should, for any reason whatsoever, be declared invalid
     by a court of competent jurisdiction, the validity or enforcement of the
     remainder of such restrictions and covenants shall not thereby be
     adversely affected.  Each Member agrees that, if any provision of this
     Section 4.5 should be adjudicated to be invalid or unenforceable, such
     provision shall be deemed deleted therefrom with respect, and only with
     respect, to the operation of such provision in the particular
     jurisdiction in which such adjudication was made; provided, however,
     that to the extent any such provision may be made valid and enforceable
     in such jurisdiction by limitations on the scope of the activities,
     geographical area or time period covered, the Members agree that such
     provision instead shall be deemed limited to the extent, and only to the
     extent, necessary to make such provision enforceable to the fullest
     extent permissible under the laws and public policies applied in such
     jurisdiction.

     4.6  Confidential Information.

          4.6.1   Non-Disclosure: Non-Utilization.  Each Member agrees that,
     from the commencement of the Term until the end of the period specified
     in Section 4.6.4 and regardless of whether the Member is still a Member
     or has ceased to be a Member, except as otherwise consented to by the
     Required Members, all non-public confidential or proprietary information
     furnished to it pursuant to this Agreement or otherwise in connection
     with the Company's operation of its business, including without
     limitation, any and all information concerning the Company's suppliers
     and customers and the Company's business dealings with such Persons
     ("Confidential Information), will be kept confidential and will not be
     disclosed or utilized by such Member, or by any of its agents,
     representatives, employees or Affiliates (or any employee, agent or
     representative thereof), in any manner or for any purpose whatsoever, in
     whole or in part, except that (a) each Member shall be permitted to
     disclose such Confidential Information to those of its agents,
     attorneys, accountants, financial and business consultants, other
     representatives, and employees who need to be familiar with such
     Confidential Information in connection with such Member's investment in
     the Company and who are charged with an obligation of confidentiality,
<PAGE>
     (b) each Member shall be permitted to disclose such Confidential
     Information to financial institutions and bona fide prospective
     purchasers and capital investors when such Persons are charged with an
     obligation of confidentiality, (c) each Member shall be permitted to
     disclose such Confidential Information to its members, partners and
     stockholders so long as they agree not to utilize such Confidential
     Information in their own business or that of any Affiliate in any way
     and to keep such Confidential Information confidential (including from
     any Affiliate) on the terms set forth herein, (d) each Member shall be
     permitted to disclose Confidential Information to the extent required by
     law, so long as such Member shall have first afforded the Company with a
     reasonable opportunity to contest the necessity of disclosing such
     Confidential Information, (e) each Member shall be permitted to disclose
     Confidential Information to the extent necessary for the enforcement of
     any right of such Member arising under this Agreement and (f) each
     Member shall be permitted to disclose that Confidential Information
     expressly permitted by the Required Members to be disclosed.  No Member,
     nor any officer, agent, representative or Affiliate of a Member, nor any
     officer, agent or representative of the Company shall disclose the terms
     of this Agreement to any Person except (i) to the extent required by law
     or (ii) for legitimate business purposes approved by the Required
     Members.  For purposes of this Agreement, Confidential Information shall
     not include any information (other than proprietary compilations of
     information that is non-confidential or is in the public domain) which
     (a) is within the public domain prior to the time it is furnished or
     thereafter comes within the public domain other than as a result of any
     disclosure by a Member in violation of the terms of this Agreement, (b)
     was in the possession of a Member on a non-confidential basis prior t
     the execution of this Agreement or (c) is obtained by a Member from a
     third party not known by the Member to be under any confidentiality
     obligation to the Member, whether by contractual, legal or fiduciary
     obligation or otherwise.

          4.6.2   Precautionary Measures.  Each Member shall take such
     precautionary measures as may be required to ensure (and such Member
     shall be responsible for) compliance with this Section 4.6 by any of its
     Affiliates, and its and their directors, officers, employees, agents,
     representatives and other Persons to which it may disclose Confidential
     Information in accordance with this Section 4.6.

          4.6.3   Destruction or Return of Confidential Information.  In the
     event a Member shall cease to be a Member, it shall promptly destroy
     (and provide a certificate of destruction to the Company with respect
     to), or return to the Company, all Confidential Information of the
     Company in its possession. Notwithstanding the immediately preceding
     sentence, a Member that ceases to be a Member may retain for a stated
     period, but not disclose to any other Person, Confidential Information
     for the exclusive purposes of (A) explaining such Member's corporate
     decisions with respect to the Company or (B) preparing such Member's tax
     returns and defending audits, investigations and proceedings relating
     thereto; provided, however, that the Member must notify the Company in
     advance of such retention and specify in such notice the stated period
     of such retention.

          4.6.4   Survival of Provision Beyond Term.  The obligations of
     each Member under this Section 4.6 shall survive both the termination of
     such Member's membership in the Company and the dissolution and
     termination of the Company until, unless extended pursuant to Section
     9.9, the earlier of the fifth anniversary of the termination of such
     Member's membership or the third anniversary of the end of the Term.

     4.7  Remedies.  The Members agree that no adequate remedy at law exists
for a breach or threatened breach of any of the provisions of Section 4.5 or
Section 4.6 hereof, the continuation of which unremedied will cause the
<PAGE>
Company and the other Members to suffer irreparable harm.  Accordingly,
notwithstanding Section 16.5, 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 Section 4.5 or 4.6 and to specific performance of their rights
hereunder, as well as to any other remedies available at law or in equity.

                            ARTICLE 5

                            MANAGEMENT

     5.1  Management by the Members.  The management of the Company is fully
vested in the Members, acting exclusively in their membership capacities. Each
Member may designate by written notice to the Company and the other Member,
one or more representatives of such Member (each, a "Representative") who
shall be authorized to speak on behalf of and take actions on behalf of such
Member and, if such authorization is subject to any limits, conditions or
qualifications, shall specify the precise nature of such limits, conditions or
qualifications.  A Member's designation may be changed at any time by notice
to the Company.  In the absence of a designated Representative, the chief
executive officer of such Member shall be such Member's Representative.  The
Members expressly intend that the Company will not have "managers," as that
term is used in the Act or in Rev. Proc. 95-10, 1995-3 I.R.B. 20, it being
understood that the Representatives do not constitute "managers," but that
each Representative acts solely as the agent of the Member that appointed it.

     5.2  Meetings of Members; Consents.  Deliberations and actions of the
Members (including deliberations and actions by the Required Members) shall
occur at meetings of the Members or by written consents executed by the
Members in accordance with Section 5.10.  Meetings of the Members, for any
purpose or purposes, may be called by any Member or Members holding Interests
representing, in the aggregate, at least a 50% Percentage Interest.

     5.3  Place of Meetings.  The Required Members may designate any place,
either within or outside The Commonwealth of Massachusetts, as the place of
meeting for any meeting of the Members.  If no designation is made, the place
of meeting shall be the principal place of business of the Company.

     5.4  Notice of Meetings.  Except as provided in Section 5.5, notice
stating the place, day and hour of a meeting of Members shall be delivered in
accordance with Section 16.4 not less than forty-eight (48) hours before the
time of the meeting, by or at the direction of the Member or Members calling
the meeting, to each other Member.  The purpose or purposes of such meeting
shall be specified in such notice.

     5.5  Meeting of All Members.  If the Required Members consent to the
holding of a meeting of Members at any time and place and attend such meeting,
such meeting shall be valid without call or notice, and at such meeting any
lawful action may be taken.

     5.6  Quorum.  The Required Members, represented in person or by proxy,
shall constitute a quorum at any meeting of Members.

     5.7  Voting by Percentage Interests; Voting Thresholds.  Except as
provided otherwise in this Agreement, voting shall be according to the
Members' respective Percentage Interests; provided, however, that unless
otherwise expressly provided in this Agreement, all decisions by the Members
shall require the affirmative vote of each of the Required Members.

     5.8  Representatives and Proxies.  At any meeting of Members, a Member
shall be deemed in attendance if at least one of its Representatives is in
attendance. The vote of a Member at a meeting of Members shall be determined
by the Representatives in attendance after such consultation with the Member's
other executive officers and directors as may be required.  At any meeting of
<PAGE>
Members, a Member may instead vote by proxy executed in writing by the Member
or by a duly authorized attorney-in-fact.  Such proxy shall be filed with the
Company before or at the time of the meeting.  No proxy shall be valid after
eleven (11) months from the date of its execution, unless otherwise provided
in the proxy.

     5.9  Conference Telephone.  Any Member may participate in a meeting of
the Members by means of conference telephone or similar communications
equipment which permits all persons participating in the meeting to hear each
other, and participation in the meeting by means of such equipment shall
constitute presence in person at such meeting.

     5.10 Action by Members Without a Meeting.  Action required or permitted
to be taken at a meeting of Members may be taken without a meeting if the
action is evidenced by one or more written consents describing the action
taken, signed by the Required Members and delivered to the Company for
inclusion in the minutes or for filing with the Company records.  Action taken
under this Section 5.10 is effective when the Required Members have signed the
consent, unless the consent specifies a different effective date.

     5.11 Waiver of Notice.  When any notice is required to be given to any
Member, a waiver thereof in writing signed by or on behalf of the Member
entitled to such notice, whether before, at or after the time stated therein,
shall be equivalent to the giving of such notice.

     5.12 Advisory Board.  The Members hereby establish, for the purposes of
providing advice and counsel and making recommendations to the Members in
respect of their management of the Company, an advisory board (the "Advisory
Board").  Each Member shall designate three Persons to serve on the Advisory
Board. In addition, each of the chief executive officer and chief operating
officer of the Company will serve on such board.  The Advisory Board shall
have no authority to bind or otherwise act on behalf of the Company, nor may
the Members delegate any portion of their authority as Members to the Advisory
Board; however, the Members may take into account the advice of such Board in
exercising their rights and fulfilling their obligations as Members.  The
Advisory Board may adopt such procedures and rules as to its conduct and
proceedings as its members may from time to time determine.

     5.13 Duties and Authority of the Members.  Each Member shall have the
full power and authority to take any and all actions on behalf of or with
respect to the Company that are permitted under Massachusetts law to be taken
by members of a limited liability company; provided, however, that each Member
agrees not to take any action in the name of or on behalf of the Company
unless such action, and the taking thereof by such Member, shall have been
authorized by the Required Members or is expressly authorized by this
Agreement.  The Required Members may ratify previously unauthorized actions
taken by a Member in the name of and on behalf of the Company, which
ratification shall cure any breach by such Member of the prior sentence
arising from such actions.  Subject to the two immediately preceding
sentences, the powers and authority granted to the Members hereunder shall
include all those necessary or convenient for the furtherance of the purpose
and powers of the Company and shall include the power and authority to make
all decisions and take all actions with regard to the management, operations,
assets, financing and capitalization of the Company, including without
limitation, the power and authority to make decisions concerning, and take all
actions in respect of, all those matters specified in Section 2.6.

     5.14 Officers: Authority.  The Required Members may designate one or
more Persons to be officers of the Company and may remove any such Person as
an officer 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 Required Members may delegate to them,
including the power to execute documents, and shall serve at the pleasure of
the Required Members.  Unless the authority of the Person designated as the
<PAGE>
officer in question is limited or expanded in the document appointing such
officer or is otherwise specified by the Required Members, any officer so
appointed shall have the same authority to act for the Company as a
corresponding officer of a Delaware corporation would have to act for a
Delaware corporation in the absence of a specific delegation of authority;
provided, however, that unless such power is specifically delegated to the
officer in question either for a specific transaction or generally, no such
officer shall have the power to act in a manner that is not consistent with
the Business Plan and Annual Budget then in effect, to lease or acquire real
property, to borrow an amount of money in excess of $1,000,000, to issue
notes, debentures, securities, equity or other interests of or in the Company,
to make investments in (other than the temporary investment of surplus cash),
or to acquire securities of any Person, to give guarantees or indemnities, to
merge, consolidate, liquidate or dissolve the Company or to sell or lease all
or any substantial portion of the assets of the Company, and; provided,
however, that no such officer shall have the power to enter into, purchase,
acquire or otherwise invest in options, futures contracts, forward contracts,
collars, spot contracts or swap contracts related to the choice, purchase or
consumption of any Energy Commodity or any other financial products marketed
or used in connection therewith, unless such transaction is consistent with a
code of standards and controls for such transactions which has been approved
by the Required Members, or has otherwise specifically been approved by the
Required Members.  The Required Members, in their discretion, may by written
instrument signed by such Members ratify any act previously taken by an
officer acting on behalf of the Company.  By their signatures to this
Agreement, the Required Members hereby designate the following Persons as the
initial officers of the Company:

Chairman and Chief Executive Officer:   William H. Heil
President and Chief Operating Officer:  John H. Dickson
Vice President and Treasurer 
 (Chief Financial Officer):        Marcy L. Reed
Vice Presidents:                   Christopher G. Gulick

Company will comply with all legal requirements applicable with respect to
transactions between it and any Member or Affiliate of a Member and will not
engage in any transaction with a Member or an Affiliate of any Member without
the prior written consent of the other Members, other than any transaction

including price, at least as favorable to the Company as the Company might
obtain in an arm s-length transaction with an unaffiliated counterparty.  In
the event of such a transaction, the Company will give notice immediately to
both Members of the occurrence of such transaction and the terms on which it
was effected, unless the transaction and the terms on which it was effected
were previously approved by the Required Members. The Company shall not enter

supplier of Energy Commodities or Energy Related Products and Services without
the prior written approval of the Required Members.

                            ARTICLE 6

                      BUSINESS PLAN: BUDGET

     6.1  Business Plan.  At least 45 days prior to the-beginning of the
second and each subsequent Fiscal Year, the Required Members shall discuss and
revise the business plan of the Company then in effect (the "Business Plan")
of the Company so that the Business Plan at all times reflects the strategic
<PAGE>
plan for the Company for the then current Fiscal Year and the subsequent four
Fiscal Years.

     6.2  Annual Budget.  The Required Members shall, at least 45 days
before the beginning of each subsequent Fiscal Year, determine a budget for
the Company 

for the next Fiscal Year (the budget for the Company's first Fiscal Year and
each subsequent budget, each an "Annual Budget"); provided that if an Annual
Budget is not agreed upon for any Fiscal Year, the Annual Budget for the
preceding Fiscal Year shall remain in effect. Notwithstanding the proviso to
the immediately preceding sentence, the Members agree that if they cannot
agree on an Annual Budget, they will implement the dispute resolution
provisions of Section 16.5, provided, however, that, no arbitration shall be
required.  Each Annual Budget shall include a projected profit and loss
statement, cash flow statement and balance sheet for the next Fiscal Year, and
shall specify and quantify capital expenditures.  

                            ARTICLE 7

         DISTRIBUTIONS AND ALLOCATIONS OF PROFIT AND LOSS

     7.1  Distributions.

          7.1.1   In General.  Subject to Section 3.7.2, the Company shall
     make Distributions at such times and in such amounts as the Required
     Members shall determine; provided, that, all Distributions (other than
     Distributions in liquidation of the Company) shall be made ratably in
     accordance with the Members' Percentage Interests and all Distributions
     in liquidation of the Company shall be made in proportion to the
     Members' Capital Account balances so as to reduce each Member' 5 Capital
     Account balance to zero.

          7.1.2   Statutory Bar on Distributions.  Notwithstanding any
     provision to the contrary contained in this Agreement, the Company shall
     not make a Distribution to any Member on account of its interest in the
     Company if such Distribution would violate Section 18-607 of the Act or
     other applicable law.

          7.1.3   Withholding.  All amounts withheld pursuant to the Code or
     any provision of any federal, state, local or foreign tax law with
     respect to any payment, distribution, or allocation to the Company or
     the Members shall be treated as amounts distributed to the Members
     pursuant to Section 7.1 for all purposes under this Agreement.  The
     Company shall withhold from Distributions to, and with respect to
     allocations to, the Members and to pay over to the appropriate federal,
     state, local or foreign government any amounts required to be so
     withheld, and shall allocate any such amounts to the Members in respect
     of whose Distribution or allocation the tax was withheld.

          7.1.4   Property Distributions and Installment Sales.  The
     Required Members may from time to time determine to distribute property
     other than cash to the Members.  In such a case, such in-kind
     Distribution shall be made to the Members entitled thereto in the same
     proportions as the Members would have been entitled to cash
     distributions.  The amount by which the fair market value of any
     property to be distributed in kind to the Members exceeds or is less
     than the Book Value of such property shall, to the extent not otherwise
     recognized by the Company, be taken into account in determining Net
     Profit and Net Loss and determining the Capital Accounts of the Members
     as if such property had been sold at its fair market value immediately
     prior to its distribution.  If any assets are sold in transactions in
     which, by reason of the provisions of section 453 of the Code or any
     successor thereto, gain is realized but not recognized, such gain shall
<PAGE>
     be taken into account when realized in computing gain or loss of the
     Company for purposes of allocation of Net Profit or Net Loss under this
     Article 7, and, if such sales shall involve substantially all the assets
     of the Company, the Company shall be deemed to have been dissolved and
     terminated notwithstanding any election by the Members to continue the
     Company for purposes of collecting the proceeds of such sales.

     7.2  Allocations of Net Profits.  Subject to Section 7.4, the Net
Profit of the Company shall be allocated among the Members ratably in
accordance with their Percentage Interests.

     7.3  Allocation of Net Losses.  Subject to Section 7.4, the Net Loss of
the Company shall be allocated among the Members ratably in accordance with
their Percentage Interests.

     7.4  Other Allocation Provisions.  Prior to making the allocations of
Net Profit or Net Loss for the Fiscal Year in accordance with Sections 7.2 and
7.3, income, gain, loss, deduction and credit (and items thereof) shall be
allocated in accordance with the provisions of this Section 7.4 to the extent
required by the Code and applicable Regulations.  Any amounts allocated
pursuant to this Section 7.4 shall not again be allocated under Section 7.2 or
7.3.

          7.4.1   Qualified Income Offset: Nonrecourse and Member
     Nonrecourse Deductions.  There is hereby included in the Agreement such
     provisions governing the allocation of income, gain, loss, deduction and
     credit (and items thereof) as may be necessary to provide that the
     Company's allocation provisions contain a so-called "Qualified Income
     Offset provision and comply with all provisions relating to the
     allocation of so-called Nonrecourse Deductions" and "Member Nonrecourse
     Deductions" and the chargeback thereof as set forth in the Regulations
     under Section 704(b) of the Code. Allocations of Nonrecourse Deductions
     shall be made ratably among the Members in accordance with their
     Percentage Interests.  In allocating Net Profits pursuant to Section 7.2
     hereof, the Required Members shall take into account (and, if necessary,
     modify the allocations to reflect) anticipated future allocations under
     the minimum gain chargeback rules of Regulation sec. 1.704-2.

          7.4.2   Special Adjustments.  To the extent that an adjustment to
     the adjusted tax of any Company asset is required pursuant to Section
     734(b) or Section 743(b) of the Code and is required, pursuant to
     Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in
     determining Capital Accounts, the amount of such adjustment to the
     Capital Accounts shall be treated as an item of gain (if the adjustment
     increases the basis of the asset) or loss (if the adjustment decreases
     such basis), and such gain or loss shall be specially allocated to the
     Members in a manner consistent with the manner in which their Capital
     Accounts are required to be adjusted pursuant to such Section of the
     Regulations.

          7.4.3   Recourse Indebtedness.  In the event that indebtedness of
     the Company is recourse to one or more, but not all, of the Members, the
     Required Members, with the advice of independent accountants, shall make
     such modifications to the allocation provisions of Sections 7.2 and 7.3
     as it shall determine to be appropriate.

          7.4.4   Limitation on Net Losses.  Notwithstanding any other
     provision of this Agreement to the contrary, Net Loss shall not be
     allocated to any Member if such allocation would cause such Member to
     have an Adjusted Capital Account Deficit or increase such Member's
     Adjusted Capital Account Deficit.  To the extent an allocation of Net
     Loss would cause or increase an Adjusted Capital Account Deficit as to
     any Member, the limitation set forth in this Section 7.4.4 shall be
     applied on a Member by Member basis in accordance with the Members'
<PAGE>
     respective Percentage Interests so as to allocate the maximum
     permissible Net Loss to each Member without causing any Member to have
     an Adjusted Capital Account Deficit.

     7.5  Changes in Members' Interests.  If during any Fiscal Year of the
Company there is a change in any Member's Interest in the Company, the
Required Members shall confer with the tax advisors to the Company and, in
conformity with such advice allocate the Net Profit or Net Loss to the Members
so as to take into account the varying Interests of the Members in the Company
in a manner that complies with the provisions of Section 706 of the Code and
the Regulations thereunder.

     7.6  Tax Allocations.

          7.6.1   In General.  Subject to Section 7.6.2, each item of
     income, gain, loss and deduction, as determined for federal income tax
     purposes, shall be allocated among the Members in the same manner as its
     correlative item of "book" income, gain, loss or deduction is allocated
     pursuant to Sections 7.2 through 7.5.

          7.6.2   Section 704(c) Allocations.  In the event there is a
     difference between the Book Value at which any property is accepted as a
     contribution to the capital of the Company (or deemed accepted pursuant
     to Regulation Section 1 .704-1(b)(2)(iv)(g)) and the adjusted tax basis
     of such property to the Company, the Company shall, solely for federal
     income tax purposes, specially allocate the income, gain, loss and
     deduction attributable to such property as and to the extent required by
     Section 704(c) of the Code and any applicable Regulations under Section
     704(b) or Section 704(c) of the Code.

     7.7  Tax Credits.  All foreign tax credits of the Company for a Fiscal
Year (or portion thereof, if appropriate) shall be allocated among the Members
in the same proportion as the net income and gains of the Company that were
subject to the foreign taxes that gave rise to such credits.  All other items
of federal income tax credit shall be allocated among the Members in
accordance with their Percentage Interests.

     7.8  Adjustment of Capital Accounts.  Unless the Members shall
determine otherwise, the Book Values of all the Company's assets shall be
adjusted to equal their respective gross fair market values, as determined by
the Required Members (and the Capital Accounts of the Members shall be
adjusted accordingly by treating any increase in Book Value as an item of Book
Gain and any decrease in Book Value as an item of Book Loss), as of the
following times: (a) the acquisition of an additional Interest in the Company
by any new or existing Member in exchange for more than a de minimis
additional Capital Contribution; (b) the distribution by the Company to a
Member of more than a de minimis amount of assets of the Company as
consideration for an Interest; and (c) the liquidation of the Company;
provided, however, that adjustments pursuant to clauses (a) and (b) above
shall be made only if the Required Members reasonably determine that such
adjustments are necessary or appropriate to reflect the relative economic
interests of the Members in the Company.

     7.9  Interpretation.  It is the intent of the Members that the Company
be treated as a partnership for federal tax purposes and that the provisions
hereof relating to each Member's distributive share of income, gain, loss,
deduction, and credit (and items thereof) comply with the provisions of
Sections 704(b), 704(c), 706 and other relevant provisions of the Code and the
applicable Regulations.  In furtherance of the foregoing, the Members hereby
agree that they will seek to resolve any ambiguity in the provisions of this
Agreement in a manner that will preserve and protect the tax allocations
provided for in this Article 7 for federal income tax purposes and, subject to
the last sentence hereof, to adopt such curative provisions to offset the
effect of the allocations required by Section 7.4 as they may deem necessary.
<PAGE>
Notwithstanding the foregoing, no Member shall have the right to require or
compel any distribution of cash or property not authorized or provided for by
the provisions of this Agreement or to alter any distribution of cash or
property provided for by the provisions of this Agreement on the ground that
such action is necessary to cause the provisions hereof to conform to the
provisions of the Regulations.

     7.10 Loans to Company.  Nothing in this Agreement shall prevent any
Member from making secured or unsecured loans to the Company by agreement with
the Company.

                            ARTICLE 8

                        TAX MATTERS MEMBER

     8.2  Indemnity of Tax Matters Member.  The Company shall indemnify and
reimburse the Tax Matters Member for all expenses (including legal and
accounting fees) incurred as Tax Matters Member pursuant to this Article 8 in
connection with any administrative or judicial proceeding with respect to the
tax liability of the Members as long as the Tax Matters Member has determined
in good faith that its course of conduct was in, or not opposed to, the best
interest of the Company.  The payment of all such expenses shall be made
before any Distributions are made to the Members.  The taking of any action
and the incurring of any expense by the Tax Matters Member in connection with
any such proceeding, except to the extent provided herein or required by law,
is a matter in the sole discretion of the Tax Matters Member and the
provisions on limitations of liability of the Tax Matters Member and
indemnification set forth in Article 13 shall be fully applicable to the Tax
Matters Member in its capacity as such.

     8.3  Information Furnished.  To the extent and in the manner provided

best efforts to keep each Member informed of any administrative and judicial
proceedings for the adjustment at the Company level of any item required to be
taken into account by a Member for income tax purposes or any extension of the

respect to any Company item, or of any agreement with the Internal Revenue
Service that would result in any material change either in income or loss as
previously reported.

     8.5  Notices to Tax Matters Member.  Any Member that receives a notice
of an administrative proceeding under Code Section 6233 relating to the
Company shall promptly notify the Tax Matters Member of the treatment of any
Company item on such Member's federal income tax return that is or may be
inconsistent with the treatment of that item on the Company's return.  Any
Member that enters into a settlement agreement with the Internal Revenue
Service or any other government agency or official with respect to any Company
item shall notify the Tax Matters Member of such agreement and its terms
within sixty days after its date.

     9.2  Delivery to Members; Inspection.  Upon the request of any Member
for any purpose reasonably related to such Member's Interest as a Member of
the Company:

          9.2.1   The Company shall promptly deliver to the requesting
     Member, at the expense of the Company, a copy of the information
     required to be maintained by Sections 10.1.1. through 10.1.4.

          9.2.2   The Members may review, at the Company's office during

bodies.

                            ARTICLE 10

                     AMENDMENTS TO AGREEMENT

     10.1 Amendments.  This Agreement may be amended or modified with the
prior written consent of the Required Members; provided, that, the Members
expressly agree that in the event of a Transfer of all or a portion of a
Member's Interest or the admission of a new Member, this Agreement shall be
revised to reflect such Transfer or such admission, as the case may be, and to
amend such provisions of this Agreement as the Members shall determine to be
appropriate, it being contemplated that in the event that either Member
Transfers all of its Interest to another Person and such Person is admitted as
a Member, such Person shall be subject to all of the provisions of this
Agreement to which the transferor Member was previously subject.

     10.2 Filings.  The Members shall cause to be prepared and filed any
amendment to the Certificate that may be required to be filed under the Act as
a consequence of any amendment to this Agreement.

                            ARTICLE 11

                      DISSOLUTION OF COMPANY

     11.1 Termination of Membership.  No Member shall resign or withdraw
from the Company and any attempted resignation or withdrawal shall be, and is
hereby declared, null and void ab initio, except that, (i) subject to the
restrictions set forth in Article 9, any Member may Transfer its Interest in
the Company and the transferee may become a Member in place of the Member
which transferred its Interest and (ii) subject to the provisions of Section
9.6, any Member may withdraw from the Company in connection with its making of
a Buy-Sell Offer.  If any Member ceases to be a Member for any reason, the
business of the Company may be continued by the remaining Members (so long as
there are two such remaining Members) as provided in clause (d) of Section
12.2. The Members agree that the unauthorized resignation or withdrawal of a
Member may cause irreparable injury to the Company and other Member for which
monetary damages (or other remedies at law) are inadequate in view of (i) the
complexities and uncertainties in measuring the actual damages that would be
sustained by reason of such unauthorized resignation or withdrawal and (ii)
the uniqueness of the Company's business and the relationship between the
Members.  Accordingly, the Members agree that the provisions of this Section
12.1 may be enforced by specific performance.

     11.2 Events of Dissolution or Liquidation.  The Company shall be
dissolved upon the happening of any of the following events: (a) a Regulatory
Dissolution Election unless the Special Purchase Right is exercised,
(b)December 31, 2096 unless such date is extended pursuant to Section 2.4, (c)
the unanimous written determination of the Members, (d) the withdrawal,
bankruptcy or dissolution of any Member, unless there are at least two
remaining Members and the business of the Company is continued by the consent
of remaining Members holding Interests that together represent more than a 50%
Percentage Interest within 90 days following the occurrence of any such event,
or (e) the entry of a decree of judicial dissolution under Section 18-802 of
the Act.

     11.3 Liquidation.  If the Company is dissolved and not continued, the
Company shall immediately commence to wind up its affairs.  A reasonable
period of time shall be allowed for the orderly termination of the Company's
business, discharge of its liabilities, and distribution or liquidation of the
<PAGE>
remaining assets so as to enable the Company to minimize the normal losses
attendant to the liquidation process. The Company's property and assets or the
proceeds from the liquidation thereof shall, subject to the requirements of
the Act, be distributed in accordance with Section 12.4, after the Members'
Capital Accounts have been adjusted to reflect all Net Profits and Net Losses
of the Company through the date of distribution (including Net Profits and Net
Losses arising from the revaluation of the Company's assets pursuant to
Section 7.8; provided, however, that in the event of a liquidating
distribution resulting from a Regulatory Dissolution Election, the gross fair
market values of the Company' s assets shall not be adjusted pursuant to
Section 7.8 and shall be deemed to equal their Book Values).  A full
accounting of the assets and liabilities of the Company shall be taken and a
statement thereof shall be furnished to each Member within 30 days after the
distribution of all of the assets of the Company.  Such accounting and
statements shall be prepared under the direction of the Required Members. 
Upon such final accounting, the Company shall terminate and an authorized
person, appointed pursuant to Section 2.7, shall cancel the Certificate in
accordance with the Act.

     11.4 Distributions to Members.  Distributions to Members upon
liquidation shall be made in accordance with the Members' Capital Account
balances. Notwithstanding Section 12.3 or the first sentence of this Section
12.4, the Company shall not make any Distribution pursuant to this Section
12.4 unless the Required Members shall have determined that the Company has
sufficient assets to pay all accrued and contingent liabilities of which the
Required Members are aware after making reasonable inquiry.

     11.5 No Action for Dissolution.  The Members acknowledge that
irreparable damage would be done to the goodwill and reputation of the Company
if any Member should bring an action in court to dissolve the Company under
circumstances where dissolution is not required by Section 12.2.  This
Agreement has been drawn carefully to provide fair treatment of all parties
and equitable payment in liquidation of the Interests of all Members. 
Accordingly, except where the Members have failed to liquidate the Company as
required by Section 12.2 and except as specifically provided in Section
18-802(a) of the Act, each Member hereby waives and renounces its right to
initiate legal action to seek dissolution or to seek the appointment of a
receiver or trustee to liquidate the Company.

     11.6 No Further Claim.  Upon dissolution, each Member shall look solely
to the assets of the Company for the return of its Capital Contributions, and
if the Company's property remaining after payment or discharge of the debts
and liabilities of the Company, including debts and liabilities owed to one or
more of the Members, is insufficient to return the aggregate Capital
Contributions of each Member, a Member shall have no recourse against the
Company or any other Member except to the extent that the other Member has
received Distributions in excess of those to which such Member was entitled to
under the terms of this Agreement.

                            ARTICLE 12

                         INDEMNIFICATION

     12.1 General.  To the maximum extent permitted by law, the Company
shall indemnify, defend, and hold harmless each Member, including the Tax
Matters Member, and each Member's officers, trustees, directors, partners,
members, shareholders, and employees (and each such Person's officers,
trustees, directors, partners, members, shareholders, and employees), and the
employees and officers of the Company (all indemnified persons being referred
to as "Indemnified Persons"), from any liability, loss, or damage incurred by
the Indemnified Person by reason of any act performed or omitted to be
performed by the Indemnified Person in connection with the business of the
Company and from liabilities or obligations of the Company imposed on such
Person by virtue of such Person's position with the Company, including
<PAGE>
attorneys' fees and costs and any amounts expended in the settlement of any
such claims of liability, loss, or damage; provided however, that, if the
liability, loss, damage, or claim arises out of any action or inaction of an
Indemnified Person, indemnification under this Section 13.1 shall be available
only if (a) either (i) the Indemnified Person, at the time of such action or
inaction, determined, in good faith, that its or his course of conduct was in,
or not opposed to, the best interests of the Company, or (ii) in the case of
inaction by the Indemnified Person, the Indemnified Person did not intend its
or his inaction to be harmful or opposed to the best interests of the Company,
and (b) the action or inaction did not constitute fraud or a Violation of the
Business Judgment Rule by the Indemnified Person, and provided, further, that
indemnification under this Section 13.1 shall be recoverable only from the
assets of the Company and not from any assets of the Members.  The Company may
pay or reimburse attorneys' fees of an Indemnified Person as incurred, if such
Indemnified Person executes an undertaking to repay the amount so paid or
reimbursed if there is a final determination by a court of competent
jurisdiction that such Indemnified Person is not entitled to indemnification
under this Article 13.  The Company may pay for insurance covering liability
of the Indemnified Persons for negligence in operation of the Company  s
affairs.

     12.2 Persons Entitled to Indemnity.  Any Person who is within the
definition of "Indemnified Person" at the time of any action or inaction in
connection with the business of the Company shall be entitled to the benefits
of this Article 13 as an "Indemnified Person" with respect thereto, regardless
whether such Person continues to be within the definition of "Indemnified
Person" at the time of such Person's claim for indemnification or exculpation
hereunder.

     12.3 Procedure Agreements.  The Company may enter into an agreement
with any of its officers and employees setting forth procedures consistent
with applicable law for implementing the indemnities provided in this Article
13.
