                  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. The Limited Partner shall not

                  5.8.1. General Rules. The General Partner shall maintain a
capital account and an income account for each Partner. Except as otherwise
provided herein, each Partner's capital account shall be maintained in
accordance with Treasury Regulation Section 1.704-1(b)(2)(iv). There shall be
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

the Partnership shall not be credited to the lending Partner's income or capital
account. Distributions (whether constituting principal or interest) to a lending

                  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

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 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 bold
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
Partnership may be reconstituted and its business continued without being wound
up if there remains at least one general partner. The business of the
Partnership may be carried on by any such remaining general partner.

                                  ARTICLE VII

         7.1. Reimbursement of Certain Costs. The General Partner shall be
reimbursed promptly by the Partnership for all actual, reasonable, and necessary
expenditures made from time to time on behalf of the Partnership in connection
with the affairs of the Partnership, or the performance of the duties of the
General Partner hereunder.

                                  ARTICLE VIII

                           DISSOLUTION AND LIQUIDATION

                  8.2.2. Application of Proceeds. The proceeds of such
liquidation and any unsold assets shall be applied in the following order of
priority:

                  (i) first, to the expenses of such liquidation;

                  (ii) second, to the debts and liabilities of the Partnership
                  to third parties, if any, in the order of priority provided by
                  law;

                  (iii) third, to a reasonable reserve to be set up to provide
                  for any contingent or unforeseen liabilities or obligations of
                  the Partnership to third parties (to be held and disbursed, at
                  the reasonable discretion of the General Partner, by an escrow
                  agent selected by it) and at the expiration of such period as
                  the General Partner may reasonably deem advisable, the balance
                  shall be distributed as provided herein;

                  (iv) fourth, to all loans that any Partner may have made and
                  any other debts or liquidated obligations of the Partnership
                  to the Partners;

                  (v) fifth, to the Partners until they shall have received back
                  the amounts shown in, and in the proportions of, their capital
                  accounts; and


                                       9



                  (vi) sixth, the remaining assets of the Partnership, if any,
                  shall be distributed to the Partners (or their successors and
                  assigns) in accordance with their respective Ownership
                  Interests.

                  8.2.3. Restoration of Negative Capital Account. If, upon the
liquidation of the Partnership or the liquidation of a Partner's interest in the
Partnership, a Partner shall have a negative balance in his capital account,
after giving effect to all adjustments to the capital account of such Partner
pursuant to Article IV and Section 5.8, then notwithstanding anything herein,
such Partner shall contribute to the Partnership cash in the amount of such
deficit balance. Contributions made under this Section shall be made by the end
of the taxable year of the Partnership in which the liquidation of the
Partnership or the liquidation of such Partner's interest in the Partnership
occurs (or, if later, within ninety days after the date of such liquidation);
and shall be used first to satisfy any amounts then owing by the Partnership to
its creditors to the extent that such creditors have recourse to the assets of
the Partners; any remaining amount shall be distributed to the Partners having
positive balances in their capital accounts in proportion to such positive
balances. Notwithstanding anything herein, a Partner required to make a
contribution pursuant to this Section 8.2.3 shall be personally liable to make
such contribution. For purposes of this Section 8.2.3, the term "liquidation"
shall have the meaning given it in the first two sentences of Treasury
Regulation Section 1.704-1(b)(2)(i)(g).
