2.1 MEMBERS. The names and addresses of the Members, their capital commitments
to the Company and their membership interests in certain allocations and

extent otherwise provided in the Act.

2.3 MEETINGS OF MEMBERS.

(a)      Meetings of Members may be called for any proper purpose at any time
         by a majority of the Membership Interests. The Members calling the
         meeting shall determine the date, time and place of each meeting of
         Members, and written notice thereof shall be given to each Member not
         less than seven days nor more than 60 days prior to the date of the
         meeting. Notice shall be sent to Members of record on the date when
         the meeting is called. The business of each meeting of Members shall
         be limited to the purposes described in the notice. A written waiver
         of notice, executed before or after a meeting by a Member or its
         authorized attorney shall be deemed equivalent to notice of the
         meeting.

(b)      Persons holding a majority in interest in the Membership Interests
         shall constitute a quorum for the transaction of any business at a
         meeting of Members. Members may attend a meeting in person or by proxy.
         Members may also participate in a meeting by means of conference
         telephone or similar communications equipment that permits all Members
         present to hear each other. If less than a quorum of the Members is
         present, the meeting may be adjourned by the chairman to a later date,
         time and place, and the meeting may be held as adjourned without
         further notice. When an adjourned meeting is reconvened, any business
         may be transacted that might have been transacted at the original
         meeting.

2.4 ACTION WITHOUT A MEETING. There is no requirement that the Members hold a
meeting in order to take action on any matter. Any action required or permitted
to be taken by the Members may be taken without a meeting if one or more written
consents to such action shall be signed by Members who hold the Membership
Interests or other interest in the Company required to approve the action being
taken. Such written consents shall be delivered to the principal office of the
Company and unless otherwise specified shall be effective on the date when the
first consent is so delivered. Prompt notice shall be given to all Members who
did not consent to any action taken by written consent of Members without a
meeting.

2.5 VOTING RIGHTS. Unless otherwise required by the Act or this Agreement, all
actions, approvals and consents to be taken or given by the Members under the
Act, this Agreement or otherwise shall require the affirmative vote or written
consent of Members holding a majority of the Membership Interests.

2.6 LIMITATION OF LIABILITY OF MEMBERS. Except as otherwise provided in the Act,
no Member of the Company shall be obligated personally for any debt, obligation
or liability of the Company or of any other Member, whether arising in contract,
tort or otherwise, solely by reason of being a Member of the Company. Except as
otherwise provided in the Act, by law or expressly in this Agreement, no Member
shall have any fiduciary or other duty to another Member with respect to the
business and affairs of the Company, and no Member shall be liable to the
Company or any other Member for acting in good faith reliance upon the
provisions of this Agreement. No Member shall have any responsibility to restore
any negative balance in its Capital Account (as




                                      -4-

defined in Section 6.1) or to contribute to or in respect of the liabilities or
obligations of the Company or return distributions made by the Company except as
required by the Act or other applicable law; PROVIDED, HOWEVER, that Members are
responsible for their failure to make required Capital Contributions under
Section 6.2. The failure of the Company to observe any formalities or
requirements relating to the exercise of its powers or the management of its
business or affairs under this Agreement or the Act shall not be grounds for
making its Members responsible for the liabilities of the Company.

2.7 NO RIGHT TO WITHDRAW. No Member shall have any right to resign or withdraw
from the Company without the consent of the other Members or to receive any
distribution or the repayment of its Capital Contributions except as provided in
Section 7.2 and Article IX upon dissolution and liquidation of the Company. No
Member shall have any right to have the fair value of its Membership Interest in
the Company appraised and paid out upon the resignation or withdrawal of such
Member or any other circumstances.


                                  ARTICLE III.
                                   MANAGEMENT

3.1 GENERAL. Except as otherwise specifically provided in this Agreement, the
business, property and affairs of the Company shall be managed directly by the
Members. The Members shall have the full and complete right, power and authority
to do on behalf of the Company all things which, in the judgment of a majority
in interest of the Members, are necessary or desirable to carry out the purposes
of the Company as set forth in this Agreement or as required by law. Approval by
or action taken by a majority in interest of the Members in accordance with this
Agreement shall constitute approval or action by the Company and shall be
binding on all of the Members.

3.2 TAX MATTERS MEMBER. The Member so designated by a majority the Membership
Interests from time to time shall serve as the "Tax Matters Member" of the
Company for purposes of Section 6231(a)(7) of the Internal Revenue Code of 1986,
as amended (the "Code"), with power to manage and represent the Company in any
administrative proceeding of the Internal Revenue Service. The initial Tax
Matters Partner of the Company shall be AFG Investment Trust A.

3.3 COMPENSATION. The Members shall not be entitled to receive a management fee.
All reasonable expenses incurred with respect to the organization, operation and
winding down and liquidation of the Company, including without limitation legal,
accounting and licensing expenses, shall be borne by the Company. The Members
shall be entitled to reimbursement from the Company for such expenses paid by
them.


                                   ARTICLE IV.
                                 INDEMNIFICATION

4.1 DEFINITIONS.  For purposes of this Article IV:

(a)      "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




                                      -5-

         or alleging that a Manager received an improper personal benefit,
         any judgments, awards, fines, penalties and reasonable amounts paid
         in settlement of a proceeding; and

(b)      "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.

4.2 RIGHT TO INDEMNIFICATION. No Member shall be liable to any Member or to the
Company for honest mistakes of judgment or negligence or for losses due to such
mistakes or negligence or for the negligence, whether of omission or commission,
dishonesty or bad faith of any employee or other agent of the Company selected
with reasonable care. A Member shall be fully protected and justified with
respect to any action or omission taken or suffered by it in good faith in
reliance upon and in accordance with the opinion or advice as to matters of law
of legal counsel, or as to the matters of accounting of accountants, in each
case selected by a majority in interest of the Members with reasonable care.

4.3 AWARD OF INDEMNIFICATION. The determination of whether the Company is
authorized to indemnify a Member hereunder and any award of indemnification
shall be made in each instance by (a) a majority of the Members who are not
parties to the proceeding in question, (b) independent legal counsel appointed
by the Members, or (c) the holders of a majority of the Membership Interests of
the Members who are not parties to the proceeding in question. The Company shall
be obliged to pay indemnification applied for by a Member unless there is an
adverse determination (as provided above) within 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 a Member is adjudged
liable to the Company, indemnification hereunder shall be provided to such
Member only upon a determination by a court having jurisdiction that in view of
all the circumstances of the case, such Member is fairly and reasonably entitled
to indemnification for such expenses as the court shall deem proper.

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

4.5 ADVANCE PAYMENTS. Except as limited by law, expenses incurred by a Member in
defending any proceeding, including a proceeding by or in the right of the
Company, shall be paid by the Company to the Member in advance of final
disposition of the proceeding upon receipt of its written undertaking to repay
such amount if the Member 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 Member to make repayment; PROVIDED, HOWEVER, that
no such advance payment of expenses




                                      -6-

shall be made if it is determined pursuant to Section 4.3 on the basis of the
circumstances known at the time (without further investigation) that the Member
is ineligible for indemnification.

4.6 INSURANCE. The Company shall have power to purchase and maintain insurance
on behalf of any Member, 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.

4.7 NON-EXCLUSIVITY. The provisions of this Article IV shall not be construed to
limit the power of the Company to indemnify its 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 IV.

4.8 AMENDMENT. The provisions of this Article IV may be amended or repealed in
accordance with Section 10.5; PROVIDED, HOWEVER, that no amendment or repeal of
such provisions that adversely affects the rights of a Member under this Article
IV with respect to its acts or omissions at any time prior to such amendment or
repeal shall apply to such Member without its consent.


                                   ARTICLE V.
                              CONFLICTS OF INTEREST

5.1 TRANSACTIONS WITH INTERESTED PERSONS. Unless entered into in bad faith, no
contract or transaction between the Company and one or more of its Members, or
between the Company and any other corporation, partnership, association or other
organization in which one or more of its Members have a financial interest or
are directors, partners, managers or officers, shall be voidable solely for this
reason or solely because such Member was present or participated in the
authorization of such contract or transaction if:

(a)      the material facts as to the relationship or interest of such
         Member and as to the contract or transaction were disclosed or known
         to the other Members and the contract or transaction was authorized
         by the disinterested Members; or

(b)      the contract or transaction was fair to the Company as of the time it
         was authorized, approved or ratified by the disinterested Members;

and no Member interested in such contract or transaction, because of such
interest, shall be considered to be in breach of this Agreement or liable to the
Company or Member, or any other person or organization for any loss or expense
incurred by reason of such contract or transaction or shall be accountable for
any gain or profit realized from such contract or transaction.




                                      -7-

                                  ARTICLE VI.
                       CAPITAL ACCOUNTS AND CONTRIBUTIONS

6.1 CAPITAL ACCOUNTS.

(a)      There shall be established on the books of the Company a separate
         capital account (a "Capital Account") for each Member.

(b)      The Capital Account of each Member (regardless of the time or manner in
         which such Member's interest was acquired) shall be maintained in
         accordance with the rules of Section 704(b) of the Code, and Treasury
         Regulation Section 1.704-1(b)(2)(iv). Adjustments shall be made to the
         Capital Accounts for distributions and allocations as required by the
         rules of Section 704(b) of the Code and the Treasury Regulations
         thereunder.

(c)      If there is a transfer of all or a part of an interest in the Company
         by a Member, the Capital Account of the transferor that is attributable
         to the transferred interest shall carry over to the transferee of such
         Member.

(d)      Notwithstanding any other provision contained herein to the contrary,
         no Member shall be required to restore any negative balance in its
         Capital Account.

6.2 CAPITAL CONTRIBUTIONS. The capital commitment of each Member shall be as set
forth in Schedule A under the column marked "Capital Commitment." Each Member
shall contribute 6.67% of the amount of its capital commitment to the Company
immediately upon execution of this Agreement, and shall thereafter make
contributions to the capital of the Company at such times and in such amounts as
may be requested, if at all, upon reasonable notice by a majority in interest of
the Members (each a "Capital Contribution"). No Member shall be required to make
Capital Contributions to the Company in an aggregate amount in excess of his or
her Capital Commitment; PROVIDED, HOWEVER, the Company may borrow from its
Members as well as from banks or other lending institutions to finance its
working capital or the acquisition of assets or for other purposes upon such
terms and conditions as shall be approved by the Members, and any such borrowing
from Members shall not be considered Capital Contributions or reflected in their
Capital Accounts. The value of all non-cash Capital Contributions made by
Members shall be set forth on SCHEDULE A hereto. No Member shall be entitled to
any interest or compensation with respect to its Contribution or any services
rendered on behalf of the Company except as specifically provided in this
Agreement or approved by the Members. No Member shall have any liability for the
repayment of the Contribution of any other Member and each Member shall look
only to the assets of the Company for return of its Contribution.


                                  ARTICLE VII.
                        PROFITS, LOSSES AND DISTRIBUTIONS

7.1 PROFITS, LOSSES AND DISTRIBUTIONS.

(a)      All profits and losses arising from the normal course of business
         operations or otherwise and all cash available for distribution from
         whatever source, commencing with the date of this Agreement, shall be
         allocated or distributed to the Members according to their respective
         Membership Interests.

(b)      All profits and losses allocated to the Members shall be credited or
         charged, as the case may be, to their Capital Accounts. The terms
         "profits" and "losses" as used in this




                                      -8-

         Agreement shall mean income and losses, and each item of income, gain,
         loss, deduction or credit entering into the computation thereof, as
         determined in accordance with the accounting methods followed by the
         Company and computed in a manner consistent with Treasury Regulation
         Section 1.704-1(b)(2)(iv). Profits and losses for federal income tax
         purposes shall be allocated in the same manner as profits and losses
         for purposes of this Article VII, except as provided in Section 7.3(a).

7.2 DISTRIBUTIONS UPON DISSOLUTION.

(a)      Upon dissolution and termination, after payment of, or adequate
         provision for, the debts and obligations of the Company, the remaining
         assets of the Company (or the proceeds of sales or other dispositions
         in liquidation of the Company assets, as may be determined by the
         remaining or surviving Member(s)) shall be distributed to the Members
         in accordance with the positive balances in their Capital Accounts
         after taking into account all Capital Account adjustments for the
         Company taxable year. No Member shall be liable to the Company or any
         other Member for any negative balance in its Capital Account.

(b)      With respect to assets distributed in kind to the Members in
         liquidation or otherwise, (i) any unrealized appreciation or unrealized
         depreciation in the values of such assets shall be deemed to be profits
         and losses realized by the Company immediately prior to the liquidation
         or other distribution event, and (ii) such profits and losses shall be
         allocated to the Members and credited or charged to their Capital
         Accounts, and any property so distributed shall be treated as a
         distribution of an amount in cash equal to the excess of such fair
         market value over the outstanding principal balance of and accrued
         interest on any debt by which the property is encumbered. For the
         purposes of this Section 7.2(b), "unrealized appreciation" or
         "unrealized depreciation" shall mean the difference between the fair
         market value of such assets, taking into account the fair market value
         of the associated financing but subject to Section 7701(g) of the Code,
         and the Company's basis in such assets as determined under Treasury
         Regulation Section 1.704-1(b). This Section 7.2(b) is intended to
         provide a rule for allocating unrealized gains and losses upon
         liquidation or other distribution event, and nothing contained in this
         Section 7.2(b) or elsewhere in this Agreement is intended to treat or
         cause such distributions to be treated as sales for value. The fair
         market value of such assets shall be determined by an appraiser or
         other method to be selected by the Members.

7.3 SPECIAL PROVISIONS. Notwithstanding the foregoing provisions in this Article
VII:

(a)      Income, gain, loss and deduction with respect to Company property which
         has a variation between its basis computed in accordance with Treasury
         Regulation Section 1.704-(b) and its basis computed for Federal income
         tax purposes shall be shared among Members so as to take account of the
         variation in a manner consistent with the principles of Section 704(c)
         of the Code and Treasury Regulation Section 1.704-3.

(b)      Section 704 of the Code and the Treasury Regulations issued thereunder,
         including but not limited to the provisions of such regulations
         addressing qualified income offset provisions, minimum gain chargeback
         requirements and allocations of deductions




                                      -9-

         attributable to nonrecourse debt and partner nonrecourse debt, are
         hereby incorporated by reference into this Agreement.

7.4 DISTRIBUTION OF ASSETS IN KIND. No Member shall have the right to require
any distribution of any assets of the Company to be made in cash or in kind. If
a majority in interest of the Members determine to distribute assets of the
Company in kind, such assets shall be distributed on the basis of their fair
market value as determined by a majority in interest of the Member. Any Member
entitled to any interest in such assets shall, unless otherwise determined by a
majority in interest of the Members, receive separate assets of the Company, and
not an interest as tenant-in-common with other Members so entitled in each asset
being distributed. Distributions in kind need not be made on a pro-rata basis
but may be made on any basis which a majority in interest of the Members
determine to be reasonable under the circumstances.


                                 ARTICLE VIII.
                             TRANSFERS OF INTERESTS

8.1 TRANSFER OF A MEMBER'S MEMBERSHIP INTEREST. The unanimous vote of the
non-assigning Members shall be required for the assignment, pledge, mortgage,
hypothecation, sale or other disposition or encumbrance of all or any part of
any Member's interest in the Company (collectively, a "Transfer"), which consent
may be withheld for any or no reason. The Members shall not cause or permit
interests in the Company to become "traded on an established securities market"
and shall withhold their consent to any Transfer that, to any Member's knowledge
after reasonable inquiry, would otherwise be accomplished by a trade on a
"secondary market (or the substantial equivalent thereof)," in each case within
the meaning of Sections 7704 or 469(k) of the Code and any regulations
promulgated thereunder that are in effect at the time of the proposed Transfer.
Any Transfer of a Member's interest in the Company which requires a unanimous
vote hereunder shall be made only upon receipt of a written opinion of counsel
for the Company or of other counsel reasonably satisfactory to the Company
(which opinion shall be obtained at the expense of the transferor) that such
Transfer will not result in (a) the Company or the Members being subjected to
any material additional regulatory requirements, (b) a violation of applicable
law or this Agreement, (c) the Company being classified as an association
taxable as a corporation or the Company otherwise being taxed as a corporation,
or (d) any adverse tax consequences to any Member to the extent the Transfer
results in the Company being deemed terminated pursuant to Section 708(b)(1)(B)

Agreement must be in writing




                                      -11-

address of the principal office of the Company specified in Section 1.3.

or written agreements or understandings with respect to the Company. This
Agreement is binding on and inures to the benefit of the parties and their

those transactions.

10.7 WAIVER OF CERTAIN RIGHTS. Each Member irrevocably waives any right it may
have to maintain any action for dissolution of the Company or for partition of
the property of the Company. The failure of any Member to insist upon strict
performance of a covenant hereunder or of any obligation hereunder, irrespective
of the length of time for which such failure continues, shall not be a waiver of
such Member's right to demand strict compliance herewith in the future. No
consent or waiver, express or implied, to or of any breach or default in the
performance of any obligation hereunder shall constitute a consent or waiver to
or of any other breach or default in the performance of the same or any other
obligation hereunder.

10.8 THIRD-PARTY BENEFICIARIES. The provisions of this Agreement are not
intended to be for the benefit of any creditor or other person to whom any debts
or obligations are owed by, or who may have any claim against, the Company or
any of its Members, except for Members in their capacities as such.
Notwithstanding any contrary provision of this Agreement, no such creditor or
person shall obtain any rights under this Agreement or shall, by reason of this
Agreement, be permitted to make any claim against the Company or any Member.
