Account shall be established and maintained in respect of each Partner.

        Section 5.2 Maintenance of Capital Accounts. Each Partner's Capital
Account shall be credited with (i) the amount of cash and the fair market value
of other property (net of liabilities that the Partnership is considered to
assume or take subject to, under Section 752 of the Code) contributed by such
Partner to the capital of the Partnership and (ii) allocations to it pursuant to
Section 7.1 of income (or items thereof) including tax-exempt income and gain. A
Partner's Capital Account shall be debited with (i) the cash and fair market
value of property distributed to such Partner (net of liabilities that such
Partner is considered to assume or take subject to, under Section 752 of the
Code), (ii) allocations to it of expenditures of the Partnership described in
Section 705(a)(2)(b) of the Code, and (iii) allocations to it pursuant to

or loss allocated among the Partners pursuant to Sections 7.1 and 7.2, and the
proceeds thereof distributed. The Partners shall maintain their Capital Accounts
in accordance with the Code and the Regulations.

        Section 5.4 Compliance with Regulations. The provisions of this
Agreement relating to the maintenance of Capital Accounts are intended to comply
with Section 1.704-1(b) of the Regulations and shall be interpreted and applied
in a manner consistent with such Regulations. In the event that the General
Partner shall determine, after consultation with the Limited Partner, that it is
prudent to modify the manner in which the Capital Accounts are computed in order
to comply with changes in such Regulations or for other reasons, the General
Partner may in its sole discretion make such modification.

ARTICLE VI. CAPITAL CONTRIBUTIONS AND PERCENTAGE INTERESTS

        Section 6.1 General Partner Capital. The General Partner, in its
capacity as General Partner, shall contribute cash or cash equivalents to the
Partnership's capital at such times as Capital Contributions are made by the
Limited Partner in an amount equal to 1.01% of the amount contributed by the
Limited Partner, as determined pursuant to Sections 6.2, 6.3 and 6.4. It is
intended that the General Partner's Capital Contributions shall result in a 1%
Percentage Interest for the General Partner.

        Section 6.2 Limited Partner Capital Contributions. The Limited Partner
shall contribute as a Capital Contribution the property described in an
assignment and assumption agreement dated as of the date hereof (the "Assignment
and Assumption Agreement"), the form of which is attached as Appendix A hereto.
Such Capital Contribution shall be a net contribution comprising certain assets
which will be assigned to the Partnership by the Limited Partner net of certain
liabilities which will be assumed by the Partnership, all pursuant to the
Assignment and Assumption or Agreement. It is intended that the Limited
Partner's Capital Contribution shall result in a 99% Percentage Interest for the
Limited Partner.

                                       8


        Section 6.3 Contributions of Property. The Partners agree that the fair
market value of the property contributed pursuant to Section 6.2 shall be as set
forth in Appendix B hereto.

        Section 6.4 Estimated Fair Market Value. If the Partners are unable, at
the time of execution of this Agreement, to establish the fair market value of
all or any part of any property contributed by the Limited Partner pursuant to
Section 6.2, the Partners may initially set forth an estimated value for such
property pending final determination of the fair market value thereof. In such
event, the General Partner's contribution pursuant to Section 6.1 shall
initially be calculated using the estimated value of such property. Adjustments
(either additional contributions from the General Partner or refund of excess
contributions to the General Partner, as the case may be) shall be effected upon
the final determination by the Partners of the fair market value of such
property.

        Section 6.5 Percentage Interests. The Partners' respective Percentage
Interests shall be the percentage determined by dividing the amount of each
Partner's Capital Account by the total of the aggregate Capital Accounts of all
Partners. It is intended that the General Partner's Percentage Interest shall be
1% and that the Limited Partner's Percentage Interest shall be 99%. In the event
that any Partnership Interest or portion thereof is transferred in accordance
with this Agreement, the transferee shall succeed to the Percentage Interest of
the transferor Partner to the extent that such Percentage Interest relates to
the transferred Partnership Interest or portion thereof.

        Section 6.6 Additional Capital Contributions. The Partners may, but
shall not be required to, make additional Capital Contributions.

                                       9


        Section 6.7 Loans to the Partnership. Loans by Partners to the
Partnership shall not be considered Capital Contributions, nor shall Capital
Contributions by the Partners be deemed loans. If any Partner advances funds to
the Partnership in excess of the amounts required hereunder or in any separate
agreement with the General Partner to be contributed by it to the capital of the
Partnership, the making of any such advance shall not result in any increase in
the amount of the Capital Account or Partnership Interest of such Partner. The
amount of any such advance shall be a debt of the Partnership to such Partner
and shall be payable or collectible only out of the Partnership Assets in
accordance with the terms and conditions upon which such advance is made.

        Section 6.8 Limitations. No Partner, without the prior written consent
of the General Partner, which consent may be withheld for any reason or for no
reason, may (i) withdraw or reduce its Capital Contribution to the Partnership,
(ii) bring an action for partition against the Partnership, (iii) except as
provided in Section 6.2, contribute or receive property other than cash as or
for its Capital Contributions, (iv) have priority over any other Partner as to
the return of its Capital Contribution or as to the Partnership's Profits,
Losses or distributions or (v) pledge, mortgage or otherwise encumber all or
part of its Partnership Interest.

        (c) Notwithstanding the foregoing provisions of this Article VII, if any
Partner unexpectedly receives an adjustment, allocation or distribution
described in paragraphs (5) or (6) of Section 1.704-1(b)(2)(ii)(d) of the
Regulations, which creates a deficit balance in its Capital Account that exceeds
such Partner's share of minimum gain, plus such Partner's obligation to restore
such deficit, such Partner shall be allocated items of income and gain in an
amount sufficient to eliminate any such deficit balance as quickly as possible
in accordance with the rules of Section 1.704-1(b)(2)(ii)(d) of the Regulations.

        Section 7.2 Gain or Loss from the Sale; Involuntary Conversion or Other
Disposition of Partnership Property. The General Partner shall allocate any

accordance with their respective Percentage Interests.

        Section 7.3 Allocations for Tax Purposes.

        (a) Except as otherwise provided in this Agreement, for Federal income
tax purposes, any item of Partnership income, gain, loss, deduction and credit
(and the character and

                                       11


source of such items) shall be allocated among the Partners in the same manner
as the corresponding item of income, gain, loss, deduction or credit is
allocated to Capital Accounts pursuant to this Article, and the Partnership
shall maintain such books, records, and accounts as are necessary to make such
allocations.

        (b) If, as a result of contributions of property by a Partner to the
Partnership, Section 704(c) of the Code requires allocations of income, gain,
loss and deduction of the Partnership in a manner different from that set forth
in this Section, the provisions of Section 704(c) of the Code and the
Regulations thereunder shall control, solely for federal income tax purposes,
with regard to allocations of items of Partnership income, gain, loss and
deduction.

        (c) If a Partner sells or exchanges a part of its interest in the
Partnership, or if the interest of a Partner is reduced, the Partner's
distributive share of items allocated pursuant to Section 7.3(a) shall be
determined as if the Partnership's books of account were closed on the date on
which such sale, exchange or reduction of interest occurred.

                                       12

all amendments thereto, the names and addresses of the Partners, information

Losses, and information relating to compensation of the Partners, or may state
such information in the aggregate rather than with respect to any individual
Partner.

        Section 10.3 Reliance of Third Parties. Any person dealing with the
Partnership shall be entitled to deal with the General Partner as if it were the
sole party in interest in the Partnership's assets and business, both legally
and beneficially. Every agreement, instrument and document executed by the
General Partner with respect to any business or property of the Partnership
shall be conclusive evidence in favor of any person relying thereon or claiming
thereunder that (i) at the time of the execution or delivery thereof, this
Agreement was in full force and effect, (ii) such agreement, instrument or
document was duly executed in accordance with this Agreement and is binding upon
the Partnership, and (iii) the General Partner was duly authorized and empowered

General Partner shall notify the other Partners of all non-routine actions
regarding the Partnership.

        Section 10.5 Admission of New Partners. The General Partner may admit
other Limited Partners on such terms and conditions as it may, in its sole
discretion, deem appropriate, provided that the rights of the existing Limited
Partners are not impaired thereby. The General Partner shall not admit any new
General Partner without the consent of all of the Limited Partners, which
consent shall not unreasonably be withheld.

        Section 10.6 General Partner Power to Amend. Provided that the other
Partners are notified within thirty days thereafter, the General Partner may
amend this Agreement to (i) add (subject to the consent of the other Partners
and to the other provisions of this Agreement) to the General Partner's duties
or obligations, (ii) correct any error or resolve any ambiguity in or
inconsistency among the provisions of this Agreement, (iii) delete or add any
provision required to be deleted or added by any state securities commission or
similar governmental authority for the benefit or protection of the other

Partnership or add Limited Partners, subject to Section 10.6 above, or (v) make
any change that in the General Partner's sole opinion is necessary or prudent to
satisfy any requirement, condition or guideline contained in any opinion,
directive, order or ruling of any U.S., state, regional, or local agency or
judicial authority, or contained in any U.S., state, or local statute, code or
regulation. However, such amendments shall not without the consent of each
affected Partner: (i) reduce any Partner's Percentage Interest, (ii) change the
liabilities of any Partner, (iii) convert any Limited Partner to a General
Partner, (iv) allow any Limited Partner to exercise control of the Partnership's
business or (v) otherwise adversely affect any other Partner.

any document that may be required in connection with any such amendment.

consent of all other Partners, nothing in this Agreement shall authorize the
General Partner to:

        (a) Manage the affairs or business of the Partnership in a manner
contrary to this Agreement;

        (b) Sell, trade, give or otherwise alienate the Partnership's Assets
except in the ordinary course of business or in a liquidation;

        (c) Negligently do any act that would subject any Limited Partner to
liability as a general partner in any jurisdiction or that would cause the
Partnership to be classified as other than a partnership for federal income tax
purposes; and

borrow money without the consent of the other Partners, which consent shall not
be unreasonably withheld.

other things:

        (a) Whether the transfer may violate any agreement or any law or other
governmental requirement or prohibition;

qualification as a limited partnership under the Act or result in a termination
of the Partnership under Section 708 of the Code; and

        (c) Whether the transfer may cause the Partnership to be classified
other than as a partnership for federal or state tax purposes.

                                       21

regarding the Partnership's tax returns shall survive the termination of the

regarding the federal income taxation of the Partnership and items of
Partnership income, gain, loss and deduction.

        Section 13.4 Tax Policy. The General Partner shall make any and all tax

partner in the Partnership and due to any Claim against, or related to, the
Partnership or the Partnership's assets, business or activities, become liable,
or be subject to any Claim, in excess of its Partnership Interest, the other
Partners, each in proportion to its Percentage Interest, shall indemnify and
