the Indeck Members or their respective Affiliates, the Members hereby
authorize and direct the Company to enter into and perform agreements between
the Company and Ridgewood or its Affiliates on terms and conditions which are
not in any material respect less favorable to the Company than the terms and
conditions of the agreements between the Company and the Indeck Members and

immediatesly preceeding the date of termination thereof; and

ARTICLE VII
ALLOCATION OF PROFITS AND LOSSES

7.1 Allocations of Profits and Losses.
(a) General Rules. Except as otherwise provided in Section 7.1(b)
or Section 7.1(c)(i) and after giving effect to the allocations set forth in
Section 7.1(c)(ii) and 7.1(c)(iii), all Profits and Losses shall be allocated
among the Members in the following order of priority:

(i) FIRST, there shall be allocated to each Member (other than
Ridgewood) with respect to each Fiscal Year, Profits (including gross income
and gain, if necessary) so that the cumulative amount of Profits allocated
pursuant to this Section 7.1(a)(i) is equal to the cumulative amount of the
distributions theretofore made or to be made to each such Member pursuant to
Sections 8.1(b) and 8.1(c) with respect to such Fiscal Year; and

(ii) SECOND, all remaining items of Profits and Losses, and
other items in the nature of income, gain, loss or deduction shall be
allocated to Ridgewood.

(b) Depreciation. All Depreciation shall be allocated to
Ridgewood.

(i) LOSS LIMITATIONS. The Losses and Depreciation allocated
to any Member pursuant to Sections 7.1(a) and (b) with respect to any Fiscal
Year shall not exceed the maximum amount of Losses and Depreciation that can
be so allocated without causing such Member to have an Adjusted Capital
Account Deficit at the end of such year. All Losses and Depreciation in
excess of the limitation set forth in this Section shall be allocated to the
remaining Members who will not be subject to this limitation, in proportion to
and to the extent of their positive Capital Account balances.

(ii) QUALIFIED INCOME OFFSET. If in any Fiscal Year a Member
unexpectedly receives an adjustment, allocation or distribution described in
Regulations (( 1.704-1(b)(2)(ii)(d)(5) or (6), and such allocation or

distribution causes or increases an Adjusted Capital Account Deficit for such

Fiscal Year, such Member shall be allocated items of income and gain

(consisting of a pro rata portion of each item of Company income, including

gross income and gain) in an amount and manner sufficient to eliminate such
Adjusted Capital Account Deficit as quickly as possible.

(iii) LIMITED EFFECT; CURATIVE ALLOCATIONS. The special rules
set forth in this Section 7.1(c) hereof (the "Regulatory Allocations") are
intended to comply with certain requirements of the Code and Regulations. The

Members do hereby acknowledge and agree that the Regulatory Allocations may
not be consistent with the manner in which the Members intend to divide
Company Losses and similar items. Accordingly, the Tax Matters Member is
hereby authorized and directed to divide other allocations of Profits, Losses,
and other items of income, gain, loss and deduction among the Members in any
reasonable manner so as to prevent the Regulatory Allocations from distorting
the manner in which the Members intend to divide Company Profits, Losses and
similar items. In general, the Members anticipate that this will be
accomplished by specially allocating other Profits, Losses, and other items of
income, gain, loss and deduction among the Members so that, after such
offsetting special allocations are made, the amount of each Member's Capital
Account will be, to the extent possible, equal to the Capital Account balance
such Member would have had if the Regulatory Allocations were not a part of
this Agreement and all Profits, Losses and similar items had been allocated to
the Members solely pursuant to Sections 7.1(a) and (b) hereof.

7.2 Tax Allocations.

(a) Generally. Allocations for tax purposes of items of income,
gain, loss and deduction, and credits and basis therefor, shall be made in the
same manner as allocations of Profits, Losses and similar items as provided
for in Section 7.1. Allocations pursuant to this Section 7.2 are solely for
purposes of federal, state and local income taxes and shall not affect, or in
any way be taken into account in computing, any Partner's Capital Account or
share of Profits, Losses, other items or distributions pursuant to any
provision of this Agreement.

(b) Special Rules.

(i) Elimination of Book/Tax Disparities. If any Company
property has a book value different from its adjusted tax basis to the Company
for federal income tax purposes (whether by reason of the contribution of such
property to the Company, the revaluation of such property hereunder, or
otherwise), allocations of taxable income, gain, loss and deduction under this
Section 7.2 with respect to such asset shall take account of any variation
between the adjusted tax basis of such asset for federal income tax purposes
and its book value in the same manner as under Code Section 704(c) or the
principles set forth in Regulations ( 1.704-1(b)(2)(iv)(g), as the case may

be. Any elections or other decisions relating to such allocations shall be

made by the Tax Matters Member in such manner as reasonably reflects the

purpose and intention of this Agreement.

(ii) Allocation of Separately Stated Items Among Partners.

Each item of income, gain, loss, deduction and credit governed by Code Section
702(a) shall be allocated among the Members in proportion to the allocation of
Profits, Losses and similar items as provided for in Section 7.1.

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

7.3 Allocation Rules for Changes in Membership Interests. If there is a
change in any Member's share of the Company's Profits, Losses or similar items
during any Fiscal Year, including any change resulting from a Member's
transfer of all or any portion of its membership interest, allocations among
the Members shall be made in accordance with their interests in the Company
from time to time during such Fiscal Year in accordance with Code Section 706,
using the closing-of-the-books method, except that Depreciation and similar
items shall be deemed to accrue ratably on a daily basis over the entire
Fiscal Year during which the corresponding asset is owned by the Company for
the entire year, and over the portion of a Fiscal Year after such asset is
placed in service by the Company if such asset is placed in service during the
Fiscal Year.

7.4 Reimbursements. All of the Company's expenses shall be billed
directly to and paid by the Company.

ARTICLE VIII
DISTRIBUTIONS

8.1 Distributions. The Company shall make the following distributions:

(a) Closing Distribution. Upon the Closing of the Purchase
Agreement, the Company shall make a distribution (the "Closing Distribution")
to the Indeck Members (in accordance with the respective interests of the
Indeck Members as shown on Exhibit 8.1), in the amount of (i) $13,000,000,
(ii) less the amounts required to discharge all existing indebtedness of the
Company, including without limitation amounts payable to Indeck Power
Overseas, Ltd. in respect of a promissory note dated ▇▇▇▇▇ ▇▇, ▇▇▇▇, (▇▇▇)
less amounts expended prior to the Effective Date to bring each Project into
operating condition, including without limitation amounts payable to Indeck
Energy Services, Inc. and any of its Affiliates that have paid Company
expenses or advanced funds to the Company, and (iv) plus the amounts of any
prepaid expenses of the Company determined in accordance with generally
accepted accounting principles as of the Effective Date.

Since the exact amount of the Closing Distribution will not be known
on the date of closing of the Purchase Agreement, the Company shall make a
preliminary distribution (the "Preliminiary Closing Distribution") on the date
of closing of an estimated amount determined by the Board of Managers, subject
to a reasonable reserve. Within sixty (60) days after closing, the Board of
Managers shall detemine the exact amount of the Closing Distribution and the
Company shall make a final distribution of the excess of the Closing
Distribution over the amount of the Preliminary Closing Distribution, or the
Indeck Members shall return to the Company an amount equal to the excess of
the Preliminary Closing Distribution over the amount of the Closing
Distribution, as the case may be.

(b) Distribution of Net Cash Flow From Operations. For each Fiscal
Year, the Company shall distribute Net Cash Flow From Operations to the
Members in the following order of priority:

(i) FIRST, the Company shall distribute to Ridgewood one
hundred percent (100%) of Net Cash Flow From Operations until Ridgewood has
received the full amount of any unpaid portion of Ridgewood's Priority Return
From Operations for any preceding Fiscal Year;

(ii) SECOND, the Company shall distribute to Ridgewood one
hundred percent (100%) of Net Cash Flow From Operations until Ridgewood has
received Ridgewood's Priority Return From Operations for the current Fiscal
Year;

(iii) THIRD, the Company shall distribute one hundred percent
(100%) of Net Cash Flow From Operations to the Indeck Members (in accordance
with the respective interests of the Indeck Members as shown on Exhibit 8.1)
until the Indeck Members have collectively received an amount equal to the
amount distributed to Ridgewood with respect to the current Fiscal Year
pursuant to Section 8.1(b)(ii) above.

(iv) FOURTH, after the Company has satisfied all the preceding
distribution requirements of this Section 8.1(b), the Company shall thereafter
distribute any remaining balance of Net Cash Flow From Operations twenty-five
percent (25%) to Ridgewood, and seventy-five percent (75%) to the Indeck
Members (in accordance with the respective interests of the Indeck Members as
shown on Exhibit 8.1), provided however that at such time as Ridgewood shall
have received aggregate distributions equal to Ridgewood's Initial Capital
Contribution pursuant to Section 8.1(c) below, the distribution percentages
set forth in this Section 8.1(b)(iv) shall be amended to fifty percent (50%)
to Ridgewood and fifty percent (50%) to the Indeck Members.

(c) Distributions of Net Cash Flow From Capital Events. The
Company shall distribute Net Cash Flow From Capital Events to the Members
fifty percent (50%) to Ridgewood and fifty percent (50%) to the Indeck Members
(in accordance with the respective interests of the Indeck Members as shown on
Exhibit 8.1); provided, however, to the extent that Net Cash Flow From Capital
Events is attributable to events which may have a material adverse effect upon
the ability of the Facilities to operate in the ordinary course consistent
with past practices (such as insurance or condemnation proceeds), such
proceeds shall be applied first to restore the normal operating capabilities
of the Facilities prior to any distributions to Members.

8.2 Procedure. Distributions under Sections 8.1(b) and 8.1(c) shall be
made by the Company on a quarterly basis within fifteen (15) days after the
end of each calendar quarter, based upon good faith estimates for the Fiscal
Year made by the Board of Managers with due

regard for all information available to the Board of Managers at the time such
distributions are made. Each quarterly distribution shall be made by the
Company as an interim advance against final determination of the results of
operations for such Fiscal Year. Within one hundred twenty (120) days after
the end of each Fiscal Year, the Board of Managers shall determine Net Cash
Flow From Operations and Net Cash Flow From Capital Events, and the
distributions due to the Members with respect to such Fiscal Year. Any excess
of the amount so determined for a Member over the amount of interim advances
received by such Member shall be distributed as soon as reasonably practicable
after the amount of such Member's distribution has been determined, but in no
event later than one hundred thirty (130) days after the end of such Fiscal
Year. Any excess of interim advances paid to a Member over the amount of
distributions determined to be due such Member for any Fiscal Year shall be
repaid to the Company by such Member within ten (10) days of the receipt of
written notice from the Company that excess advances were made, and, to the
extent not repaid, may be offset against future distributions to such Member.
Until distributed, amounts due to the Members under this Article VIII shall be
held in trust by the Company for the Persons entitled to distribution thereof.

ARTICLE IX
TRANSFER OF MEMBERSHIP INTERESTS AND
RESIGNATION OF MEMBERS

9.1 Assignment and Transfer of Membership Interests. An Indeck Member
may sell, assign, pledge or otherwise transfer its interest in the Company to
any other Person, and such person shall become a Substituted Member (as such
term is used in the Act), only after the Member wishing to transfer his or her
interest has received the prior written consent of Ridgewood, which consent
shall not be unreasonably withheld so long as the transfer will not result in
a termination of the Company under section 708 of the Internal Revenue Code.
Ridgewood may sell, assign, pledge or otherwise transfer its interest in the
Company to any other Person, and such Person shall become a Substituted Member
(as such term is used in the Act), only after Ridgewood has received the prior
written consent of the holders of a majority of the Indeck Members, which
consent shall not be unreasonably withheld. A purported transfer made by a
Member in violation of this Section 9.1 shall be null and void ab initio, and
the purported transferee shall have no right to participate in the management
of the business and affairs of the Company or to become a Member. The
admission of a transferee as a Member may be conditioned upon satisfaction of
such terms and compliance with such conditions as Ridgewood and the holders of
a majority of the interests of the Indeck Members (other than the Member
effecting the transfer) may determine, including, without limitation,
requiring the transferee to execute such agreements, instruments and other
documents as may be necessary or desirable to substitute the transferee for
the transferring member hereunder.

9.2 Resignation.

(a) Generally. Resignation of a Member prior to the end of the
term of this Agreement shall constitute a violation of this Agreement.
However, a Member ("Resigning Member") may resign from the Company
("Resignation") by giving notice

to the Company and to each other Member ("Continuing Member"). Such
Resignation shall be effective upon receipt of notice by all such parties.

(b) Damages. In the event of a Resignation in violation of this
Agreement, the Company shall be entitled to damages as provided by the Act.
Such damages shall be offset against amounts that would be otherwise payable
to the Resigning Member as distributions.

(i) General. No Resignation by a Resigning Member shall
relieve such Member of its liabilities and obligations to the Company or the
Members which arose or accrued prior to the effective date of such
Resignation.

(ii) Use of Members' Names and Name Change Matters. From and
after the effective date of a Resignation, neither the Company nor any of its
Affiliates shall use any of the names of the Resigning Member. No later than
60 days following the effective date of such Resignation, the Company shall
obliterate the aforesaid names from all assets and properties of the Company,
including obliteration from letterhead, labelling, packaging, data sheets,
invoices, stationary, business cards and other materials distributed to third
parties, or discard and replace any such materials with materials not bearing
such names.

(d) Ridgewood's Option to Purchase Resigning Members' Interest. In
the event that any of the Indeck Members elect to resign as Members, Ridgewood
shall have the option, exercisable upon thirty (30) days written notice from
the Company that an Indeck Member has tendered its resignation, to purchase
such tendered interest from the Company for the sum of One Hundred Dollars
($100).

ARTICLE XII
INDEMNIFICATION

12.1 Right to Indemnification. Except as limited by law and subject to
the provisions of this Article, from and after the closing of the Purchase
Agreement, the Company shall indemnify the Managers against all expenses
incurred by them in connection with any proceeding in which the Managers are
involved as a result of serving in such capacity, on or after such date,
except that no indemnification shall be provided for a Manager regarding any
matters as to which it shall be finally determined that the Manager did not
act in good faith and in the reasonable belief that its action was in the best
interests of the Company, or with respect to a criminal matter, that it had
reasonable cause to believe that its conduct was unlawful. Subject to the
foregoing limitations, such indemnification may be provided by the Company
with respect to a proceeding in which it is claimed that a Manager received an
improper personal benefit by reason of its position, regardless of whether the
claim arises out of the Manager's service in such capacity, except for matters
as to which it is finally determined that an improper personal benefit was
received by the Manager.

12.2 Award of Indemnification. The determination of whether the Company
is authorized to indemnify a Manager hereunder and any award of
indemnification shall be made in each instance (a) by a majority of the
Managers who are not parties to the proceeding in question, or (b) by
independent legal counsel appointed by the Managers. The Company shall be
obligated to pay indemnification applied for by the Manager unless there is an
adverse determination (as provided above) within forty-five (45) days after
the application. If indemnification is denied, the applicant may seek an
independent determination of its right to indemnification by a court, and in
such event, the Company shall have the burden of proving that the applicant
was ineligible for indemnification under this Article. Notwithstanding the
foregoing, in the case of a proceeding by or in the right of the Company in
which the Manager is adjudged liable to the Company, indemnification hereunder
shall be provided to the Manager only upon a determination by a court having
jurisdiction that in view of all the circumstances of

the case, the Manager is fairly and reasonably entitled to indemnification for
such expenses as the court shall deem proper.

12.3 Successful Defense. Notwithstanding any contrary provisions of
this Article, if a Manager has been wholly successful on the merits in the
defense of any proceeding in which it was involved by reason of its position
as Manager or as a result of serving in such capacity (including termination
of investigative or other proceeding without a finding of fault on the part of
the Manager), the Manager shall be indemnified by the Company against all
expenses incurred by the Manager in connection therewith.

12.4 Advance Payments. Except as limited by law, expenses incurred by a
Manager in defending any proceeding, include a proceeding by or in the right
of the Company, shall be paid by the Company to the Manager in advance of
final disposition of the proceeding upon receipt of its written undertaking to
repay such amount if the Manager is determined pursuant to this Article or
adjudicated to be ineligible for indemnification, which undertaking shall be
an unlimited general obligation but need not be secured and may be accepted
without regard to the financial ability of the Manager to make repayment;
provided, however, that no such advance payment of expenses shall be made if
it is determined pursuant to Section 12.2 of this Article on the basis of the
circumstances known at the time (without further investigation) that the
Manager is ineligible for indemnification.

12.5 Definitions. For purposes of this Article:

"Manager" includes (i) a person serving as an officer of the Company
or in a similar executive capacity appointed by the Manager and exercising
rights and duties delegated by the Manager, (ii) a person serving at the
request of the Company as a director, manager, officer, employee or other
agent of another organization, and (iii) any person who formerly served in any
of the foregoing capacities;

"expenses" means all expenses, including attorneys' fees and
disbursements, actually and reasonably incurred in defense of a proceeding or
in seeking indemnification under this Article, and except for proceedings by
or in the right of the Company or alleging that the Manager received an
improper personal benefit, any judgments, awards, fines, penalties and
reasonable amounts paid in settlement of a proceeding; and

"proceeding" means any threatened, pending or completed action, suit
or proceeding, whether civil, criminal, administrative or investigative, and
any claim which could be the subject of a proceeding.

12.6 Insurance. The Company shall have power to purchase and maintain
insurance on behalf of any Manager, officer, agent or employee against any
liability or cost incurred by such person in any such capacity or arising out
of its status as such, whether or not the Company would have power to
indemnify against such liability or cost.

12.7 Employee Benefit Plan. If the Company or the Manager sponsors or
undertakes any responsibility as a fiduciary with respect to an employee
benefit plan, then for purposes of this Article (i) "Manager" shall be deemed
to include the Manager or any officer of the Company who serves at its request
in any capacity with respect to said plan, (ii) the Manager or officer shall
not be deemed to have failed to act in good faith or in the reasonable belief
that its action was in the best interests of the Company if the Manager or
officer acted in good faith and in the reasonable belief that its action was
in the best interests of the participants or beneficiaries of said plan, and
(iii) "expenses" shall be deemed to include any taxes or penalties imposed
upon the Manager or officer with respect to said plan under applicable law.

12.8 Heirs and Personal Representatives. The indemnification provided
by this Article shall inure to the benefit of the heirs and personal
representatives of each Manager.

12.9 Non-Exclusivity. The provisions of this Article shall not be
construed to limit the power of the Company to indemnify its Manager, Members,
officers, employees or agents to the full extent permitted by law or to enter
into specific agreements, commitments or arrangements for indemnification
permitted by law. The absence of any express provision for indemnification
herein shall not limit any right of indemnification existing independently of
this Article.

12.10 Amendment. The provisions of this Article may be amended or
repealed in accordance with Section 13.2; however, no amendment or repeal of
such provisions that adversely affects the rights of the Manager under this
Article with respect to its acts or omissions at any time prior to such
amendment or repeal shall apply to the Manager without its consent.
