       3.04 Each Partner shall contribute Ten Million Dollars ($10,000,000) as
its share of the Project Equity Contribution, for a total of Thirty Million
Dollars ($30,000,000).  Such Project Equity Contributions shall be made after

On, or prior to, the Financial Closing Date, each Partner shall post one or more
letters of credit, corporate guarantees or other security, in each case
acceptable to the Lenders, to secure its obligation under this paragraph.

       3.05 (a) Following completion of the Project and except as provided in
subparagraph (b), any subsequent equity contributions shall be subject to the
unanimous approval of the Partners, and unless otherwise agreed, shall be in
accordance with the Partner Percentage of each Partner.

            (b)  In the event that one or more Partners fail to make part or
all of any subsequent equity contributions approved pursuant to subparagraph (a)
or approved by the Management Committee in order to avoid default under the
Project Documents, or which, in the reasonable judgment of the Management
Committee, may be necessary to avoid default under such Project Documents, the
interest of each such non-contributing Partner shall be subject to the following
restrictions until such time as the default is cured:

                 (i)   loss of all voting rights under this Agreement, and
                 (ii)  suspension of all distributions to which such Partner
would otherwise be entitled, with the stipulation that such distributions shall
be placed in escrow by the Management Committee until such time as the default
is either cured or the interest of the non-contributing Partner is purchased
pursuant to the procedures set out below.

            (c)  A non-contributing Partner under this Section 3.05 shall have
six (6) months from the date the Management Committee sets for payment of the
subsequent equity contribution to cure any default.  Cure shall consist of
payment in full of the subsequent equity contribution required of the Partner
plus interest on the unpaid amount at the Default Rate applicable to late
payments under the Credit Agreement.  If any such Partner has failed to cure the
default within said six (6) month period, the remaining Partners shall have the
opportunity, pro rata to their respective Partner Percentages, to purchase the
Partnership interest of the non-contributing Partner, pursuant to the provisions
of Section 22, except that the purchase price shall equal the amount of the
subsequent equity contribution which the non-contributing Partner failed to
make.

            (d)  As a condition to participating in any such buyout, a Partner
shall have paid to the Partnership, pro rata to its Partner Percentage, that
part of the capital shortfall created by the non-contributing Partner either
through an additional equity contribution to the Partnership (which shall be
added to the Partner's Capital Account) or, if approved by the Management
Committee, and permitted by the Credit Agreement, through a loan to the
Partnership.  To the extent that a Partner fails to pay its pro rata share of
the subsequent equity contribution required of the non-contributing Partner, the
remaining Partners shall have the opportunity, pro rata to their respective
Partner Percentages, to make up the shortfall, and thereby be eligible to
participate in the purchase of the noncontributing Partner's interest should a
cure not be effected by such non-contributing Partner within the six (6) months
set out herein.  If none of the Partners make up the shortfall created by the
non-contributing Partner, the contributing Partners shall take such action as
they deem appropriate.

            (e)  In addition to its other obligations under subparagraphs (a)
and (b) of this Section, each Partner agrees to contribute additional capital to
the Partnership pursuant to the provisions of this Section 3.05 to satisfy
obligations owed third parties if, as a result of such obligations, the

Managing Partner its true and lawful attorney-in-fact for the express purposes
contained in this Section 6.06 (and no others) and authorizes it to act in its
name, place, and stead and for its use and benefit, to sign, execute, certify,
acknowledge, swear to, file, publish and record (i) all amended name
certificates to be filed by the Partnership under the laws of any jurisdiction
in which the Partnership is doing business;(ii) any amendments and the
instruments described in clause (i), as now or hereafter amended, which are
required to admit any substituted Partner in accordance with the terms of this
Agreement; and (iii) all certificates of cancellation and other instruments
which shall be required by applicable law to effect the dissolution and
termination of the Partnership; provided that any such actions are taken in
accordance with the terms and provisions of this Agreement.  The power of
attorney granted herein may be exercised by any such attorney-in-fact by listing
the Partners executing any agreement, certificate, instrument, or other document
with the single signature of any such attorney-in-fact acting as attorney-in-
fact for such Partners.

       6.07      To reimburse the Managing Partner for all of its incurred in
performing its responsibilities Partnership shall provide the Managing Partner
fee of One Hundred Fifty Thousand Dollars Adjusted, which fee shall be pro-rated
on a monthly basis for any periods less than a year during which a Partner
serves as Managing Partner.  Third party expenses, including legal and
accounting costs, shall be payable by the Partnership, consistent with the
annual budget approved by the Partners.


             SECTION 7. PARTNERSHIP DECISION MAKING; MAJOR DECISIONS

       7.01      (a)  For those decisions requiring a vote of the Partners
(i.e., those decisions for which the Managing Partner does not have sole
authority under paragraph 6.01), the Partners shall have a vote equal to their
respective Partner Percentage.  The Partnership shall execute its decision
making through a Management Committee, established pursuant to sub-paragraph
(b)below.

                 (b)  The Management Committee shall consist of one non-voting
General Manager appointed by the Managing Partner, and one voting member from
each of Adwin, O'Brien and Trigen.  The Management Committee shall be chaired by
the General Manager, and shall meet quarterly at the offices of the Managing
Partner, or at such other location as may be mutually agreeable.  The agenda for
each meeting of the Management Committee will consist of an Operations Report
(which shall address Project availability, efficiency, net production, equipment
runtime, PURPA calculations, equipment condition, permit compliance, and
explanation of any downtime), a Financial Report (which shall address net
income, balance sheet, available cash, deviations from approved budgets, loan
balances, and recommendations for distributions), a Third Party Relationships
Report (which shall address relations with lenders, customers,
contractors/vendors, permitting and regulatory bodies, neighbors and the press),
and a Major Decision Report, with recommendations on Major Decisions to be made.
Minutes of the meetings of the Management Committee shall be maintained by the
General Manager and a copy served on each Partner within five (5) business days
after any meeting of the Committee.  The General Manager shall ensure that
(1) unaudited annual financial statements are ready for review and approval by
the end of February of each year and that audited financial statements are ready
for approval by the end of March of each year, (2) annual tax returns are ready
for review and approval by April 1 of each year, and (3) annual staffing plans
and proposed annual budgets are ready for review by October 1 of each year.  To
the extent possible, the Management Committee will seek to make "Major
Decisions" (as defined in Section 7.04) by consensus.  In the absence of a
consensus, the provisions of Section 7 shall control.

                 (c)  Special meetings of the Management Committee may be
called by Partners holding at least thirty-three and one-third percent (33 1/3%)
of the voting interests in the Partnership upon reasonable written or telephonic
notice to the other Partners.  Meetings of the Management Committee shall be
authorized if a quorum representing fifty-one percent (51%) or more of the
voting interests in the Partnership is represented either in person or by proxy.
Any meeting of the Management Committee may be held by conference telephone or
similar telecommunications arrangement whereby all Partners in attendance may
hear one another.  Any action that may be taken at a meeting of the Partners may
be taken, without a meeting, by the unanimous written consent of those Partners
holding voting interests sufficient to approve such action pursuant to the terms
of this Agreement.

       7.02 To avoid the appearance of any conflict of interest, the Management
Committee shall assign primary responsibility for the negotiation and monitoring
of any agreements, or amendments thereto, between the Partnership and a Partner
(or an Affiliate thereof) to a Disinterested Partner unless there is no
Disinterested Partner.  For purposes of this Agreement, a "Disinterested
Partner" as to a particular decision is one which neither (1) is a contracting
party or an Affiliate of such contracting party with respect to said decision,
nor (2) has a financial interest in the agreement that is the subject of the
decision which is materially different from the financial interest of the
remaining Partners or the Partnership, due to a separate agreement with the
contracting party or its Affiliate.  The Disinterested Partner shall have no
authority to make final decisions with respect to said agreements, but shall
have the primary responsibility for negotiating or monitoring the terms of such
agreements or amendments, subject to approval by the Partnership, as set out in
Sections 7.03 and 7.04. If the Managing Partner is not a Disinterested Partner
and is, therefore, not assigned to any such negotiation or monitoring
responsibility, it shall nevertheless assist and consult with the assigned
Disinterested Partner, including attendance at negotiation sessions, if
requested.

       7.03 With the exception of those decisions set out in Sections 7.04, any
decision which is supported by fifty-one percent (51%) or more of the voting
interests of the Partners shall be deemed to be a decision or act of the
Partnership.  Unless there is no Disinterested Partner, and notwithstanding any
provisions herein to the contrary, the vote of a majority of the voting
interests held by the Disinterested Partners (or the unanimous consent of the
voting interests held by the Disinterested Partners for decisions covered by
Section 7.04) shall be required for those actions of the Partnership which
specially affect the interests of one Partner, either because such Partner or an
Affiliate thereof has a separate contract with the Partnership involving such
decision or has a financial interest in the decision which is materially
different from the financial interests of the remaining Partners or the
Partnership, due to a separate agreement with the contracting party or its
Affiliate (such a decision is hereinafter referred to as "Affiliated Party
Decision").  Without limiting the foregoing, an Affiliated Party Decision shall
include waivers, elections, default notices and the initiation of enforcement
actions under, and the execution, modification, or termination of, contracts
between the Partnership and a Partner or Affiliate of such Partner.

       7.04 Any of the actions specified below (each, a "Major Decision") may
be taken only if agreed upon by a unanimous vote of the Disinterested Partners
with respect to any such decision if such decision involves an "Affiliated Party
Decision"; otherwise, the unanimous vote of all Partners shall be required.  The
following actions shall be covered by this paragraph:

       (a)  Any action which would change or materially or adversely affect the
purpose or business of the Partnership as specified in Section 4;

       (b)  Any issuance of additional interests in the Partnership or the
admission of any Person as a Partner;

       (c)  Any material modification to the Project Documents, including any
modification which involves an expenditure or incurrence of liability, or a
potential liability, on the part of the Partnership in excess of an annual
aggregate total of Two Hundred Thousand Dollars ($200,000), As Adjusted;

       (d)  Any execution by the Partnership of any unbudgeted agreement with a
term greater than one year or involving the expenditure or incurrence of
liability, or a potential liability, in excess of one Hundred Thousand Dollars
($100,000), As Adjusted, in the aggregate;

       (e)  Any sale, assignment, or grant of mortgage or other encumbrance
involving all or substantially all of the assets of the Partnership; provided,
however, that this clause shall not apply to the leasing or installment purchase
of office and related equipment and vehicles;

       (f)  The incurring of unbudgeted indebtedness, or a potential
indebtedness, by the Partnership in excess of One Hundred Thousand Dollars
($100,000), As Adjusted, per occurrence or Five Hundred Thousand ($500,000), As
Adjusted, in the aggregate on an annual basis;

       (g)  The determination of compensation for professionals and consultants
retained by the Partnership;

       (h)  Any material modifications to an insurance and indemnity program
for the Partnership, including any modification which involves an expenditure or
the incurrence of liability, or a potential liability, in excess of Two Hundred
Thousand Dollars ($200,000), As Adjusted, in the aggregate;

       (i)  Approval of the annual operating budget for any calendar year and
approval of any action or actions, which in the aggregate result is an increase
of greater than five percent (5%) in the expenditures or a decrease of greater
than five percent (5%) in the revenues of or to the Partnership as set forth in
the approved annual operating budget;

       (j)  The dissolution of the Partnership, except under Section 21.01(iv);

       (k)  Disposition of assets of the Partnership upon dissolution or
termination of the Partnership;

       (1)  The distribution of cash or other assets to the Partners, the
establishment of any reserves not required by the Lenders or the determination
of Disbursable Assets;

       (m)  The merger or consolidation of the Partnership with or into any
Person; and

       (n)  The decisions identified in Section 6.01(d).

       7.05 Whenever any Partner is requested to evidence its approval of or
agreement to any decision or action of any nature whatsoever that requires
consent of the Partners, the Partner to whom such request has been made shall
respond to such request with reasonable promptness.  Commensurate with the
nature of the approval, action or agreement being sought, the Partner to whom
the request is made shall advise the requesting Partner(s) of its approval or
its reasons for withholding the same.  If the request for approval, agreement or
other action is in writing, the response must also be in writing.

                           SECTION 8. TERM; TERMINATION

       8.01 The Partnership shall continue in existence until the first to
occur of the following events: (a) the date determined by unanimous decision of
the Partners to dissolve the Partnership; (b) the sale of all or substantially
all of the assets of the Partnership; (c) the withdrawal by any Partner
resulting in less than two remaining Partners, unless, if there is a sole
remaining Partner, a second Partner is admitted within the time required by
applicable law; (d) the occurrence of an event specified under applicable law
resulting in a dissolution of the Partnership unless, pursuant to applicable
law, the Partners elect to continue the business of the Partnership; (e)
December 31, 2035; or (f) the dissolution of the Partnership due to an Event of
Default or otherwise in accordance with this Agreement.

       8.02 Upon termination of this Agreement, none of the Partners shall have
any further liability to each other, except any liability which expressly
survives pursuant to Section 30.02 of this Agreement.


                          SECTION 9. SCOPE OF AUTHORITY

       9.01 Except as otherwise expressly provided in this Agreement, no
Partner shall have any authority to bind or act for, or in the name of, or
assume any obligations or responsibilities on behalf of, the other Partners or
the Partnership.  Neither the Partnership nor any Partner shall be responsible
or liable for any indebtedness of a Partner, whether incurred or arising before
or after the execution of this Agreement, except those responsibilities,
liabilities, indebtedness or obligations expressly assumed by such Partner or
the Partnership in writing.  This Agreement shall not be deemed to create a
general partnership among the Partners with respect to any activities
whatsoever, other than activities within the scope and purpose of the
Partnership.


                           SECTION 10.  INDEMNIFICATION

       10.01     Each Partner hereby indemnities and holds harmless the
Partnership as well as the other Partner(s) and their or its Affiliates,
officers, directors, employees and agents from and against any and all claims,
demands, losses, damages, liabilities, lawsuits and other proceedings, judgments
and awards, and costs and expenses (including but not limited to reasonable
attorneys' fees) arising directly or indirectly, in whole or in part, out of any
breach of the provisions of this Agreement by such Partner or its Affiliate,
director, officer, employee or agent.

       10.02     Except as provided in non-waivable provisions of applicable
law:

       (a) The Partnership hereby indemnities each Partner (and its officers,
directors, employees and agents) from and against any liability resulting from
any act omitted or performed by such Partner (or its officer, director, employee
or agent) in good faith on behalf of the Partnership and in a manner reasonably
believed by such Partner (or its officer, director, employee, or agent) to be
within the scope of the authority conferred upon such Partner by this Agreement
and in the best interests of the Partnership.

       (b)  No Partner (and no officer, director, employee or agent of a
Partner) shall be liable, responsible or accountable, in damages or otherwise,
to the Partnership or the Partners for or as a result of any act, omission or
error in judgment which was taken, omitted or made by it in good faith on behalf
of the Partnership and in a manner reasonably believed by it to be within the
scope of the authority granted to it by this Agreement and in the best interests
of the Partnership.  A Partner may consult with such legal or other professional
counsel as it may select.  Any action taken or omitted by it in good faith
reliance on, and in accordance with, the opinion or advice of such counsel shall
afford full protection and justification to it with respect to the action taken
or omitted.

       (c)  The Partnership may reimburse a Partner for all expenses, including
reasonable legal fees, and losses in connection with any suit or action
involving Partnership business (but not in connection with any action brought by
one Partner against another).  Any such indemnification and advancement of
expenses agreed to by the Partnership shall not be exclusive of any other right
available to the Partners, unless otherwise provided in extending the offer
thereof.  The Partnership shall purchase and maintain insurance on behalf of the
Partners against liability.


                      SECTION-11.  LIMITATION OF LIABILITIES

       11.01     No Partner, except as provided in Section 3.05, shall be
liable to any third Person for losses, liabilities or obligations of the
Partnership (except as otherwise expressly agreed to in writing by such Partner)
unless the assets of the Partnership shall first have been exhausted.

       11.02     Unless otherwise decided by the Partnership, the Partnership
shall not enter into any contract, lease, sublease, note, deed of trust, or
other agreement unless there is contained in such instrument an appropriate
provision which (a) limits the claims of all parties to, and beneficiaries
under, such instrument to the assets of the Partnership and (b) expressly waives
any rights of such parties and other beneficiaries to proceed against the
Partners individually.  To the extent the Partnership has entered into any
contract, lease, sublease, note or other agreement in violation of this
requirement prior to the date of this Agreement, the Partners hereby waive any
violation of the provisions of this section.

       11.03     Unless due to a Partner's willful misconduct, gross
negligence, actions taken in bad faith, or actions taken by a Partner for which
there was no basis for the Partner to form a reasonable belief that such actions
were in compliance with the Affiliated Party Decision requirements of Section
7.03, in no event shall any Partner be liable to any other Partner for indirect,
incidental, special or consequential damages including, but not limited to loss
of revenue, loss of profit, cost of capital, or loss of opportunity, regardless
of whether such liability arises out of contract, tort (including negligence),
strict liability, or otherwise.


                          SECTION 12.  CAPITAL ACCOUNTS

       12.01     A separate "Capital Account" shall be maintained for each
Partner in accordance with applicable United States Treasury regulations.  Upon
execution of this Agreement, the Capital Accounts of Adwin and O'Brien shall
consist of the Unreimbursed Development Costs set out in Exhibit A plus their
respective shares of the Project Equity Contribution set out in Section 3.03.
The Capital Account of Trigen shall consist of its share of the Project Equity
Contribution.  The resulting initial Capital Accounts of the Partners are set
out in Exhibit A. Following execution of this Agreement, the Capital Account of
each Partner shall be:

       (a)  increased by (i) the amount of cash and Fair Value of any property
(net of liabilities assumed by the Partnership and liabilities to which the
property is subject) contributed by such Partner to the Partnership pursuant to
this Agreement; (ii) the items of income and gain allocated to such Partner in
accordance with Section 13.01; and (iii) any positive adjustment to such Capital
Account by reason of an adjustment to the Carrying Value of Partnership Assets;

       (b)  decreased by (i) the amount of cash and Fair Value of any property
(net of liabilities assumed by the Partner and liabilities to which the property
is subject) distributed to such Partner by the Partnership pursuant to this
Agreement; (ii) the items of loss and deduction allocated to such Partner in
accordance with Section 13.01; and (iii) any negative adjustment to such Capital
Account by reason of an adjustment to the Carrying Value of Partnership Assets.

       12.02     Immediately prior to the distribution of any property (other
than cash) to a Partner, the Capital Account of each Partner shall be increased
or decreased, as the case may be, to reflect the manner in which the unrealized
income, gain, loss and deduction inherent in such property (that has not
previously been reflected in the Capital Accounts of the Partners) would be
allocated among the Partners in accordance with GAAP as if there had been a
taxable disposition of such property for its Fair Value.

                 SECTION 13.  ALLOCATION

       13.01     For purposes of making allocations to Capital Accounts, all
items of income, gain, loss, deduction and credit of the Partnership shall be
allocated among the Partners in accordance with their respective Partner
Percentages.

       13.02     Any allocation pursuant to Section 13.01 will, however, be
subject to any adjustment required to comply with Sections 704(b) and 704(c) of
the Code and the Treasury Regulations thereunder including, without limitation,
adjustments with respect to any nonrecourse deduction or minimum gain chargeback
within the meaning of Treasury Regulation Section 1.704-2. Any special
allocations of items pursuant to this Section 13.02 shall be taken into account,
to the extent permitted by the Treasury Regulations, in computing subsequent
allocations of income, gain, loss or deductions pursuant to Section 13.01 or
13.03 so that the net amount of any items so allocated and all other items
allocated to each Partner over the life of the Partnership shall, to the extent
possible, be equal to the amount that would have been allocated to each Partner
pursuant to Section 13.09-had such special allocation not occurred.

       13.03     For purposes of making allocations for federal, state, and
local income tax purposes, all items of income, gain, loss, deduction and credit
realized by the Partnership shall, for each fiscal period, be allocated, among
the Partners in the same manner as the correlative items of income, gain, loss,
deduction and credit were allocated pursuant to Section 13.01.


                      SECTION 14.  DISTRIBUTIONS TO PARTNERS

       14.01     Subject to Section 24, and as permitted by the Partnership's
Lenders, the Partnership shall distribute its Disbursable Assets. if any, for
each fiscal quarter to the Partners simultaneously in accordance with the
Partner Percentage of each Partner.


                     SECTION 15.  BOOKS, RECORDS AND ACCOUNTS

       15.01     The Partnership shall maintain, at its principal office, full
and accurate accounts and financial records which all Partners shall have the
right to inspect and examine during reasonable business hours.  In addition,
each Partner may designate a Person or Persons to inspect, examine and audit
such accounts and financial records and to make copies of documents deemed
appropriate during regular business hours at such Partner's sole cost and
expense.  The Managing Partner shall keep or cause such books to be kept and
shall fully and accurately enter all transactions of the Partnership in the
books.  Such books and records of account shall be maintained on the accrual
basis and shall be adequate to provide each Partner with all financial
information that may be needed by such Partner or any of its Affiliates for
purposes of satisfying the financial and tax reporting obligations of such
Partner or Affiliate.  Such books shall be closed and balanced at the end of
each fiscal year.  The Managing Partner will furnish financial statements,
prepared in accordance with GAAP, to each Partner within thirty (30) days
following the end of each quarter.  On or before March 1 of each year, the
Partnership will furnish each Partner, for the prior calendar year, audited
financial statements of the Partnership.  At the request of any Partner, the
Partnership shall give specific answers to questions upon which information is
desired from time-to-time relative to the income, assets, liabilities,
contracts, operations, condition of the property, status of any loans and any
other data with respect to the Partnership or its property.

       15.02     The Partnership shall engage as independent auditors for the
Partnership the firm recommended by the Managing Partner, and approved by the
Management Committee.  The independent auditors shall at the end of each fiscal
year (i) audit the records and accounts of the Partnership and (ii) render their
opinion on the statements of financial condition of the Partnership as of the
end of each fiscal year and related statements of income and changes in
financial condition for each fiscal year.


       SECTION 16.  TAX RETURNS; TAX ACCOUNTING; TAX ELECTIONS

       16.01     It is the intention of the parties that the relationship
created by this Agreement will, for federal, state, local and foreign tax
purposes, be treated as a partnership.  The Partners agree to take all action,
including the amendment of this Agreement and the execution of other documents,
as may be required to qualify for and receive such tax treatment.  Subject to
the provisions of Section 16.04, all of the Partnership's elections for federal
and state tax purposes, except those specifically reserved by the Code to be
made by the individual Partners, shall be determined by the "Tax Matters
Partner" (as defined in Section 16.05) and approved by the other Partners. 
Subject to the provisions of this Section 16.01, the

       Partnership's federal and state tax returns of the Partnership shall be
reviewed and approved by each Partner.  Any Partner who objects to the
presentation of any Partnership item on any such return shall so notify the
Managing Partner in writing within fifteen (15) days after the date on which the
income tax return in question was furnished to such Partner by the Partnership's
independent auditors.  Such notice shall set forth in reasonable detail the
nature of, and basis for, each such objection. copies of such notice shall be
provided to the other Partners and to the independent auditors.  If the Partners
cannot agree upon a mutually satisfactory resolution of any disputed item, any
Partner who objects to the majority decision of the Partners shall be entitled
to take an inconsistent position with respect to any unresolved items on its own
income tax return.  In all other respects each Partner shall report the results
of the operation of the Partnership on its own returns in a manner consistent
with the manner in which such results were reported by the Partnership.

       16.02     Income tax returns of the Partnership shall be prepared by the
independent auditors.  Copies of all income tax returns of the Partnership shall
be furnished to each of the Partners for review and approval by April 1 of each
year for filing such returns, including extensions, if any.  If any Partner
shall fail to approve any such return, an application for an extension of time
to file shall be timely filed.  If all Partners fail to approve the return prior
to the expiration of the extension period, the Managing Partner shall file the
return as approved by a majority-in-interest of the Partners, subject to the
provisions of Section 16.01.

       16.03     The fiscal year and the tax year of the Partnership shall end
on December 31 of each year.

       16.04     The Partnership shall, if requested by any Partner, make the
election provided under Section 754 of the Code.

       16.05     The Managing Partner is hereby designated as the "Tax Matters
Partner," pursuant to Section 6231 of the Code and the applicable regulations
thereunder.

       16.06     Prompt notice shall be given to the Partners upon receipt of
notice that the Internal Revenue Service or any other taxing authority intends
to examine Partnership tax returns for any period.  The Tax Matters Partner
shall promptly supply to the other Partners copies of any communications with
any taxing authority relating to any audit of any tax returns filed by or on
behalf of the Partnership which involve any material issue and shall take such
other steps as may be appropriate to keep the
other Partners fully informed about the course of the audit and any other
administrative or judicial proceeding relating thereto.  The Tax Matters Partner
shall not settle any material claim for additional taxes, interest or penalties,
or other adjustments to the Partnership's tax returns without first obtaining
the approval of the Management Committee.


                            SECTION 17.  BANK ACCOUNTS

       17.01     Except as otherwise required by the Lenders, all funds shall
be deposited in the name of Partnership in such account or accounts as shall be
designated by the Managing Partner.  Except as provided below or as otherwise
required by the Partnership's Lenders, all withdrawals therefrom shall be made
upon checks signed (i) by the chief executive officer, the chief operations
officer, or the chief financial officer of the Managing Partner and (ii) by such
additional person or persons as shall be designated by the Managing Partner from
time-to-time.  Any withdrawal in excess of Twenty Thousand Dollars ($20,000)
which is out of the ordinary course of business of the Partnership or outside
the scope of the approved annual budget, shall be approved in writing by the
Managing Partner and at least one other Partner.  The Managing Partner shall
have no authority to approve withdrawals to itself or its Affiliates that are
outside the scope of the approved annual budget, without the approval of the
Partnership, which decision shall not be unreasonably delayed.


                  SECTION 18.  TRANSFER OF A PARTNER'S INTEREST

       18.01     No Partner may sell, assign or encumber all or any part of its
interest in the Partnership unless each of the conditions set forth herein are
satisfied or waived by consent of the Partners; provided, however, that each
Partner may transfer all or a portion of its interest in the Partnership to an
Affiliate without the consent of, but with notice to the other Partner(s);
provided, however, that such transfer does not cause the Project to lose its
status as a "qualifying cogeneration facility" under PURPA.  Notwithstanding any
other provision of this Agreement, no Partner may sell or assign all or any part
of its interest in the Partnership if such sale or assignment would result in a
total of more than three (3) Partners in the Partnership, unless to remedy a
failed capital call under Section 3.05, or to remedy a potential violation of
the ownership requirements under PURPA, pursuant to Section 18.02 below.

       18.02     If it is determined that the ownership of interests in the
Partnership by any Partner would cause the Project to cease being a "qualifying
cogeneration facility" under PURPA or would cause the Partnership to be
regulated pursuant to the Public Utility Holding Company Act, each Partner
agrees, consistent with the provisions of the Agreement, to reduce its
Partnership Interest, pro rata to its Partner Percentage, to a level which
avoids loss of "qualifying facility" status.  Each Partner agrees that it will
not transfer any interest in the Partnership, the result of which transfer would
cause a loss of "qualifying facility" status.  No transfer shall be allowed or
be effective unless an opinion of counsel satisfactory to the Partners and the
Partnership or other evidence satisfactory to the Management Committee is
obtained stating that such transfer would not (i) cause the Partnership to be
classified as an entity other than a partnership for purposes of the Code or to
be treated as a publicly traded partnership within the meaning of Section 7704
of the Code, (ii) require registration under the Securities Act of 1933 and
would not violate or cause the Partnership to violate any applicable law, and
(iii) adversely affect the status of the Project as a qualifying facility under
PURPA.

       18.03     As a condition to the transfer of any interest, the transferee
shall execute and deliver to each remaining Partner an instrument pursuant to
which it agrees to be bound by the terms of this Agreement and such additional
instruments and documents as may be reasonably required by the remaining
Partners.  

                 SECTION 19.  FIRST RIGHT OF PURCHASE

       19.01     If, at any time, any Partner desires to sell all or any
portion of its interest (other than a sale by a Partner to any Affiliate), such
Partner shall give the other Partners notice of its intention to seek a
purchaser for such interest promptly after making the determination to do so. 
Such Partner, upon securing a bona fide offer to purchase such interest intended
to be sold shall give the other Partners notice of (a) the price (which shall be
a dollar sum), (b) the identity of the proposed purchaser (if then known to the
seller) and (c) all other terms of sale.  The Remaining Partners shall have the
right pro rata to their Partner Percentage, during the forty-five (45) day
period after the giving of the notice of the proposed sale and its terms to
enter into an agreement to purchase all of the interest specified in the notice
(which price shall be prorated if the Remaining Partners want to purchase only a
portion of the interest being offered for sale) and upon the terms set forth in
the notice.  In the event less than all of the Remaining Partners determine to
purchase the interest to be sold within the said forty-five (45) day period,
those Remaining Partners who elect to purchase shall have the right within the
ten (10) day period to purchase the interest to be sold in the same proportion
as the Partner Percentage of each purchasing Remaining Partner bears to the
total Partner Percentage of all such purchasing Remaining Partners.  If none of
the Remaining Partners elect to purchase the seller Partner's interest to be
sold within the said time periods, the selling Partner shall be free for a
period of thirty (30) days thereafter to sell the interest to be sold to the
proposed purchaser on the same terms and conditions contained in the notice to
the Remaining Partners of the proposed sale. if the said sale is not effected
within the said thirty (30) day period, any subsequent sale must again comply
with the requirements of this Section.  Settlement under any purchase agreement
entered into by one or more of the Remaining Partners pursuant to this Section
shall occur within ninety (90) days of the execution of a written purchase
agreement.


                          SECTION 20.  EVENTS OF DEFAULT

       20.01     Each of the following shall be considered to be an "Event of
Default" by a Partner:

            (a)  such Partner shall be named a debtor in any petition, whether
voluntary or involuntary, in any bankruptcy or insolvency proceeding, whether
state or federal, and such petition is not stayed or dismissed within sixty
days;

            (b)  such Partner shall enter into an assignment for the benefit of
creditors;

            (c)  such Partner shall have a receiver appointed to administer its
interest in the Partnership;

            (d)  such Partner shall have its Partnership interest seized by a
general creditor;

            (e)  it shall become unlawful for such Partner to carry on the
business of owning an interest in the Partnership;

            (f)  Except for a failure to make a capital call pursuant to
Section 3.05, such Partner defaults in the performance of, or fails to comply
with, any material obligation or agreement set out in this Agreement, and has
not cured such default within thirty (30) days after notice from any of the
remaining Partners of such default;

            (g)  such Partner commits fraud, is convicted of a crime, or
violates the Affiliated Party provisions of Section 7.02; or

            (h) such Partner is either dissolved or liquidated.

       20.02     Upon the occurrence of an Event of Default, the nondefaulting
Partner(s) may, in addition to all other remedies at law or in equity to which
such Partner(s) may be entitled, elect to purchase the defaulting Partner's
interest in the Partnership pursuant to the provisions of Section 22.


                             SECTION 21.  DISSOLUTION

       21.01     The Partnership shall dissolve upon the first to occur of (i)
termination of the Partnership pursuant to Section 8.01, (ii) such time as the
last Project Document expires by its terms and no longer requires, or
prospectively could require, administration by the Partnership, (iii) upon the
withdrawal of a Partner or upon the occurrence of an Event of Default as to a
Partner under Sections 20.01(a), (b), (c), (d), or (e), unless all of the
remaining, non-defaulting Partners agree, in writing, to continue the business
of the Partnership, or (iv) upon an Event of Default as to a Partner under
Section 20.01(f) if the non-defaulting Partners elect to dissolve the
Partnership.


       SECTION 22.  PURCHASE OF DEFAULTING PARTNER'S INTEREST

       22.01     Upon the occurrence of any Event of Default by any Partner
(the "Defaulting Partner"), the other Partner(s) (the "Remaining Partner(s)")
shall have the right to acquire the Partnership interest of the Defaulting
Partner for cash, in proportion to the respective Partner Percentage of the
Remaining Partners, or if only one Partner remains, all of the Defaulting
Partner's interest, at a price determined pursuant to the procedure set forth in
Section 22.04. If any Remaining Partner should elect not to purchase its pro
rata share of the Defaulting Partner's interest, the Remaining Partner(s) may
purchase the pro rata share of the Defaulting Partner's interest to which the
Partner who chooses not to participate in the buy out of the Defaulting
Partner's interest would otherwise be entitled.  The Remaining Partner(s) may
notify the Defaulting Partner at any time within thirty (30) days of their
knowledge of an Event of Default of its or their election to institute the
procedures set forth in Section 22.04. Upon receipt of notice of the
determination of the Net Fair Market Value of the Defaulting Partner's
Partnership interest, the Remaining Partner(s) may notify the Defaulting Partner
of its or their election to purchase the interest of the Defaulting Partner.

       22.02     The closing of any purchase pursuant to this Section 22 shall
take place at the principal office of the Partnership, unless otherwise mutually
agreed by the Remaining Partner(s), on a date specified by the Remaining
Partner(s) that is not less than ten (10) days following receipt of notice of
determination of the Net Fair Market Value of the Defaulting Partner's
Partnership interest pursuant to Sections 22.04 or 22.05. Upon closing of such
purchase, the Remaining Partner or Partners may elect to offset against the
purchase price the amount of any loss, damage or injury, the amount of which has
been established by a final nonappealable judgment, suffered by it or incurred
as a result of the default of the Defaulting Partner.

       22.03     The right of a single Remaining Partner to elect to acquire
the entire interest of the Defaulting Partner as set forth in this Section 22,
is independent of the Remaining Partner's right to elect to dissolve and
terminate the Partnership pursuant to Section 21 of this Agreement by sixty (60)
days written notice to the Defaulting Partner.

       22.04     The "Net Fair Market Value" of an interest in the Partnership
for purposes of a purchase pursuant to this Section 22 shall be determined as
follows:

            (a)  The Partners shall first attempt to agree upon the "Net Fair
Market Value" of the Partnership as a whole.  The "Net Fair Market Value" of the
Partnership shall mean the cash price at which a sophisticated purchaser would
purchase, and a sophisticated seller would sell, one hundred percent (100%) of
the interests in the Partnership, with neither party being under any compulsion
to effect such transaction and with both parties being reasonably informed as to
all material facts.

            (b)  In the event the Partners are unable to mutually agree upon
the Net Fair Market Value of the Partnership for purposes of Section 22.04
within thirty (30) days of the date the remaining Partners notify the Defaulting
Partner to institute the procedures set forth in Section 22.04, the Partners
shall then attempt to agree upon the appointment of two disinterested appraisers
who shall be members of the American Institute of Appraisers.  If the Partners
are unable to agree upon the selection of two appraisers within seventy five
days, then each Partner shall, within ten (10) days thereafter, select a single
appraiser so qualified and such two appraisers shall select a third appraiser so
qualified.  Each appraiser so selected shall furnish the Partners with a written
appraisal within ninety (90) days of the selection, setting forth such
appraiser's determination of the Net Fair Market Value of the Partnership.  The
average of the two closest valuations of such appraisers shall be treated as the
Net Fair Market Value of the Partnership, and such amount shall be final and
binding on the Partners.  The cost of such appraisal shall be an expense of the
Defaulting Partner.

            (c)  The Net Fair Market Value of the Defaulting Partner's Interest
to be purchased pursuant to this Section 22 shall equal the greater of the
positive balance, if any, in the defaulting Partners "Adjusted Capital Account"
or $100.  For this purpose, the Defaulting Partner's Adjusted Capital Account
shall equal such Partner's Capital Account on the date of the valuation of the
Net Fair Market Value plus or minus the net gain or loss which would have been
credited or debited to such account if: (i) the Partnership's assets had been
sold on such date at a price equal to the Net Fair Market Value of the
Partnership and (ii) the net gain or net loss so determined were allocated among
the Partners in accordance with the provisions of Section 13.

                             SECTION 23.  WINDING UP

       23.01     Upon dissolution of the Partnership pursuant to Section 21 the
Partnership shall immediately commence to wind up its affairs and the Managing
Partner shall proceed with reasonable promptness to liquidate the business of
the Partnership and take account of the assets and liabilities of the
Partnership as promptly as is consistent with obtaining the Fair Value of such
assets. During the period of the winding up of the affairs of the Partnership,
the rights and obligations of the Partners set forth herein with respect to the
management of the Partnership shall continue.  For purposes of winding up, the
Managing Partner shall continue to act as such subject to Section 7.02, unless
Section 6.04 applies.


                    SECTION 24.  DISTRIBUTIONS ON TERMINATION

       24.01     The proceeds from a liquidation, together with assets
distributed in kind, shall be applied and distributed in the following order:

            (a)  First, to the payment of debts and liabilities of the third-
party creditors of the Partnership, in the order of priority provided by law and
to the expenses of liquidation;

            (b)  Second, to the establishment of any reserve that the
Partnership may deem reasonably necessary for any contingent or unforeseen
liabilities of the Partnership or of the Partners arising out of or in
connection with the Partnership.  Such reserves shall be paid to a trust to be
held for the purpose of disbursing such reserves in payment of any
contingencies, and, at the expiration of such period as the Partnership shall
deem advisable, to distribute the balance thereafter remaining in the manner
provided by this Section 25;

            (c)  Third, to the payment of any net indemnity obligations owed
Trigen by either Adwin and/or O'Brien under Section 13 of the Acquisition
Agreement, subject to the requirement that any such indemnity payments be
deducted from the Unreimbursed Development Costs otherwise payable to Adwin
and/or O'Brien under subparagraph (d) below;

            (d)  Fourth, to the payment of any Unreimbursed Development Costs
as set out in Exhibit A (as adjusted pursuant to subparagraph (c)), pro rata to
the amounts owed to individual Partners;

            (e)  Fifth, to the payment of any indebtedness owed to the Partners
by the Partnership, pro rata to the amounts owed to individual Partners;

            (f)  Any balance then remaining shall be distributed to the
Partners (i) to the extent of the positive balances of their Capital Accounts
(after adjustments, if any, for payments under (c) and (d) and any net indemnity
payments owed Adwin and O'Brien by Trigen pursuant to Section 14 of the
Acquisition Agreement, which amounts, if any, shall be deducted from Trigen's
Capital Account and credited to Adwin's and O'Brien's Capital Accounts, as the
case may be), as determined after taking into account all adjustments to Capital
Accounts for the Partnership taxable year during which the liquidation occurs,
in the proportion of such positive balances and (ii) any excess over Capital
Account balances being distributed according to the Partner Percentage of each
Partner, by the end of such taxable year or, if later, within ninety (90) days
after the date of such liquidation.  For purposes of determining Capital
Accounts on liquidation, all unrealized gains, losses and accrued income and
deductions are treated as realized and recognized immediately before the date of
distribution; and

            (g)  Every reasonable effort shall be made to dispose of the assets
of the Partnership so that all distributions may be made to the Partners in
cash.  To the extent such assets are not disposed of for cash, they will be
offered to each Partner and the Partner offering the highest cash price for such
assets shall have the right to purchase them, and the proceeds from such sale(s)
distributed to the Partners as otherwise provided herein.

                        SECTION 25.  DOCUMENTS AND RECORDS

       25.01     All documents and records of the Partnership including,
without limitation, all financial records, vouchers, canceled checks and bank
statements shall be delivered to the Managing Partner upon termination of the
Partnership.  Unless otherwise approved by the Partnership, the Managing Partner
shall retain such documents and records for a period of not less than seven (7)
years and shall make such documents and records available during normal business
hours to the other Partners for inspection and copying at the other Partners'
cost and expense; provided, however, that if there is an audit or threat of
audit, such documents and records shall be retained until the audit is completed
and any tax liability finally determined.


                 SECTION 26.  COMPLIANCE WITH LEGAL REQUIREMENTS

       26.01     This Agreement, and the obligations and rights of the Partners
under this Agreement, shall be construed and applied, so as to be in conformity
with all environmental, regulatory and other laws and rules and regulations of
governmental bodies applicable to the Partnership, or any Partner, or any
Affiliate of a Partner.  In the event that this Agreement, or the performance by
any party of its obligations hereunder, shall conflict-with, or be contrary to,
any such law, rule or regulation, the parties agree to negotiate in good faith
to amend or modify this Agreement so as to comply with such law, rule or
regulation.  In furtherance thereof, the Partners acknowledge their intent to
have the Project be and remain a "qualifying cogeneration facility" under PURPA.
Accordingly and except for the provisions of Section 18.02 as to the transfer of
interests in the Partnership to maintain "qualifying cogeneration facility"
status, if the operation of any provision in this Agreement results or, with the
passage of time, will result in the loss of such "qualifying cogeneration
facility" status, the Partners agree to negotiate in good faith to amend or
modify this Agreement so as to retain and continue such "qualifying cogeneration
facility" status.
