                                       5

partnership with limited partners except as otherwise provided by the Act or
this Agreement.

         5.2.     Powers of the General Partner.

                  5.2.1.   General Powers. Without limiting the provisions of
Section 5.1, and subject only to the qualifications of Section 5.3, the General
Partner is empowered to act for and bind the Partnership with respect to all
matters and shall have full power and authority to exercise all powers that may
be lawfully exercised by the general partner of a limited partnership formed
under the Act, and third persons dealing with the Partnership shall be fully
protected in relying on any action taken or instrument executed on behalf of the
Partnership by the General Partner.

         5.3.     Limitations on Powers of the General Partner. Notwithstanding
the provisions of Sections 5.1 and 5.2, without the prior consent of the Limited
Partner, the General Partner shall not take any action that it may not lawfully

         5.4.     Limited Partners. The Limited Partner shall not participate in
or have any control over the management of the business of the Partnership or
transact any business for the Partnership. The Limited Partner shall not have
any power to sign for or bind the Partnership.

                                       6


The Limited Partner shall not have any right to withdraw from or cause the
dissolution of the Partnership or to cause the partition of its properties.

         5.5.     Books and Records. The General Partner shall maintain complete
and accurate books of the Partnership at the Partnership Office, showing the
names, addresses and Partnership Interests and capital accounts of all Partners,
and all receipts, expenditures, assets, liabilities, profits and losses of the

and affairs of the Partnership, as well as all records required by the Act. Each
Partner and his duly authorized representative shall at all reasonable times
during regular business hours, have access to and may inspect and examine the
Partnership's books or records.

         5.6.     Reports Within 90 days after the end of each year, the General
Partner shall prepare, or cause to be prepared, a report which shall include tax
reporting information required by the Partners for preparation of their
respective income tax returns.

accepted accounting practices, as such are applicable to the method of
accounting adopted by the Partnership.

         5.7.     Income Tax Elections. The General Partner, subject only to

                  5.8.1.   General Rules. The General Partner shall maintain a
capital account and an income account for each Partner. Except as otherwise

credited to the capital account of each Partner the amount of cash and the
agreed value of any Assets contributed to the deductions and credits shall be
allocated to the income accounts of the Partners as provided in Section 4.3. At
the end of each Year, and following any sale of the Partnership's assets, in
connection with the liquidation of the Partnership pursuant to Article XIII, the
income accounts of all of the Partners shall be closed out to their respective
capital account. The capital account of a Partner shall be charged with the
amount of any cash distributed and the fair market value of any Assets
distributed to such Partner. Any optional loans or advances made by a Partner to
the Partnership shall not be credited to the lending Partner's income or capital
account. Distributions (whether constituting principal or interest) to a lending
Partner in repayment of any such optional loans or advances shall not be charged
to the lending Partner's income or capital account. In connection with each
assignment of any interest in the Partnership (other than an assignment intended
only to secure payment of indebtedness or other obligation), the capital and
income accounts allocable to such interest in the Partnership shall be
transferred from the assignor to the assignee.

                  5.8.2.   Hypothetical Sale. Upon liquidation of the
Partnership or any Partner's interest in the Partnership, any unsold Partnership
assets shall be valued to determine the gain or loss that would result if such
assets were sold at their fair market value, as determined in good faith by the
General Partner, at the time of such liquidation. The capital accounts of the
Partners

                                       7


shall be adjusted to reflect the manner in which any such gain or loss would
have been allocated if such assets had been sold at such value.

         5.9.     Right to Compete. Neither the General Partner nor any of its
officers, agents or employees shall be obligated to devote its or their full
time and attention to the Partnership and its affairs, but only such time as may
reasonably be necessary for the conduct of the Partnership's business. Nothing
contained in this Agreement shall preclude the General Partner, its officers,
agents or employees from engaging in any business, or making any other
investment, even though such business, or other investment may be in competition
with the business of the Partnership. Any such activity may be undertaken with
or without notice to or participation therein by the other Partner and neither
any Partner nor the Partnership shall have any right or claim with respect to
any such activity or the income or profits therefrom.

         5.10.    Limitation on Responsibility of General Partner. The General
Partner's obligations to perform the functions enumerated herein and such other
obligations as may arise by operation of law or otherwise shall be performable
only to the extent that the Partnership from time to time has funds available
therefor, and neither the General Partner nor its Affiliates shall ever be
personally liable to furnish involuntarily its or their own funds for any such
purposes, to respond in damages, or to render specific performance. The Limited
Partner hereby further agrees to look solely to the Partnership Interest of the
General Partner for recovery of any judgment against the General Partner. In the
exercise of any of its responsibilities or authority under this Agreement or
otherwise, the General Partner shall be obligated to act in good faith; and so
long as it acts in good faith, it shall have no liability or obligation to the
Partnership or to any Partner for any decision, act or omission, whether or not
such decision, act or omission shall have been authorized or reasonably prudent,
and whether or not such decision, act or omission shall have been the result of
the exercise of good or bad business judgment.

                                   ARTICLE VI

                 ASSIGNMENT OR TRANSFER OF INTEREST BY PARTNERS

         6.1.     Conditions of Transfer. Partnership Interests are
transferable, provided, however, that no Partnership Interest, or any portion
thereof, may be transferred without the consent of the other Partner.

         6.2.     Partner Representations. Each of the Partners, by execution of
this Agreement, and each assignee or transferee of a Partner by acceptance of
the rights and interests of his assignor or transferor in the Partnership,
represents and warrants to and covenants and agrees with the Partnership and the
other Partner that such Partner's interest has been acquired under this
Agreement for such Partner's own account, for investment, and not with a view to
or for sale in connection with any distribution thereof or with any present
intention of distributing or selling such interest. The Limited Partner hereby
further represents and warrants to the Partnership and the General Partner as
follows:

                                    (i)      The Limited Partner has such
                           knowledge and experience in financial and business
                           matters, including investing in or dealing with real
                           estate ventures similar to that of the Partnership,
                           that it is capable of

                                       8


                           evaluating the merits and risks of an investment in
                           the Partnership. The Limited Partner is able to bear
                           the economic risk of an investment in the
                           Partnership, including the risk of holding
                           indefinitely any Partnership Interest acquired
                           hereunder.

                                    (ii)     The Limited Partner has been
                           afforded full access to representatives of the
                           General Partner for purposes of such inquiry as such
                           Limited Partner deems appropriate, and all
                           information requested by the Limited Partner
                           concerning the Partnership has been supplied.

                                    (iii)    The Limited Partner recognizes that
                           the Partnership is engaged in an enterprise of high
                           and inherent risks.

         6.3.     Indemnification. Each Partner agrees to indemnify and hold
harmless the Partnership and the other Partner, their respective agents and
representatives and the Affiliates of each of the foregoing, from and against
any and all loss, claims, damage or liability directly or indirectly related to,
arising from or incurred in connection with any breach of the covenants,
representations and warranties of this Article VI (including any
misrepresentation or omission related thereto) by such Partner.

         6.4.     Substituted Limited Partner. An assignee or transferee (other
than an existing Partner) of the interest of the Limited Partner may be admitted
as a Substituted Limited Partner only with the consent of the General Partner
and shall be admitted as of the date of such consent. The granting or denying of
such consent shall be in the absolute discretion of the General Partner. Unless
the assignee is the General Partner, any assignee of a Partnership Interest to
whose admission such consent is given (a "Substituted Limited Partner") shall
become and shall have only the rights and duties of a limited partner of the
Partnership, and the assigned Partnership interest shall thereafter be a Limited
Partnership Interest. Any transferee of the interest of the Limited Partner
shall be entitled only to receive distributions hereunder until such transferee
has been admitted as a limited partner of the Partnership.

         6.5.     Effect of Change in Partners. Subject to all of the provisions
of this Agreement, and to the extent permitted under applicable law, the
dissolution, liquidation, bankruptcy or substitution of the Limited Partner
shall not interrupt the continuity of or cause the termination or dissolution of
the Partnership.

         6.6.     Reconstitution. Upon dissolution of the Partnership, the
