               (e)  Borrower or Guarantor or any party acting at the behest
of Borrower or Guarantor challenges the validity or enforceability of this
Guarantee, the Note, the Security Instruments or the other Loan Documents
and/or Borrower or Guarantor or any party acting at the behest of Borrower or
Guarantor asserts defenses (other than (1) the defense of payment in full of
the Obligations, provided that no other Event of Default has occurred and is
continuing, or (2) a defense made in good faith as to the improper exercise
of Lender's remedies under the Note, the Security Instruments or the other
Loan Documents, provided that no Event of Default has occurred and is
continuing at the time of Lender's exercise of such remedies) to the validity
or enforceability of this Guarantee, the Note, the Security Instruments or
the other Loan Documents, in each case solely for the purpose of delaying,
hindering or impairing Lender's rights and remedies under this Guarantee, the
Note, the Security Instruments or the other Loan Documents.

misapplies or misappropriates Rents, tenant security deposits, insurance
proceeds or condemnation awards;

               (g)  Borrower's failure to comply with the provisions of
Section 3.3, 3.9, 4.2. 4.3. 12.1, 12.2, 13.1, 13.2, 13.3, 13.4 or 13.5 of the
Security Instruments;

               (h)  Borrower defaults under Section 8.2 or 8.3 of the
Security Instruments;

               (i)  a voluntary bankruptcy or insolvency proceeding is filed
or instituted by Borrower or Guarantor, or an involuntary bankruptcy or
insolvency proceeding is filed or instituted against Borrower or Guarantor
which is not dismissed within ninety (90) days of the filing thereof (unless
such involuntary proceeding is brought by Lender); or

               (j)  any financial information concerning Borrower or the
Guarantor provided in this Guarantee, the Note, the Security Instruments or
the other Loan Documents or otherwise in order to induce Lender to make the
loan evidenced by the Note is fraudulent in any respect, contains any
fraudulent information or misrepresents in any material respect the financial
condition of Borrower or any Guarantor or Indemnitor;

          The Guarantor also agrees to pay any and all costs and expenses
(including, without limitation, all reasonable fees and disbursements of
counsel) which may be paid or incurred by Lender in connection with the
enforcement of this Guarantee. The foregoing shall not in any manner impair
or release the debt evidenced by the Note or the other Loan Documents or
otherwise impair or derogate from the Lender's ability to enforce its rights
under the Loan Documents.

          2.   Guarantee Absolute. The Guarantor guarantees that, to the
extent of the Guaranteed Obligations, the Debt will be paid strictly in
accordance with the terms of the Security Instruments regardless of any
requirement of law, regulation or order now or hereafter in effect in any
jurisdiction affecting any of such terms or the rights of Lender with respect
thereto. The liability of the Guarantor hereunder shall be absolute and
unconditional irrespective of:

               (a)  any lack of validity or enforceability of the Note, the
Security Instruments, the other Loan Documents or any other agreement between
Lender and the Borrower relating thereto;

               (b)  any change in the time, manner, place of payment of the
indebtedness under, or in any other term of, or any other amendment or waiver
of, or any consent to, departure from, any agreement between the Borrower and
Lender, including, without limitation, the Note, the Security Instruments or
the other Loan Documents;

               (c)  the insolvency of, or voluntary or involuntary
bankruptcy, assignment for the benefit of creditors, reorganization or other
similar proceedings affecting, the Borrower or any of its assets; or

               (d)  any other circumstance which might otherwise constitute a
defense available to, or a discharge of, the Borrower in respect of the Debt
or of the Guarantor in respect of this Guarantee.

          No payment made by the Guarantor, any other guarantor or any other
Person, or received or collected by the Lender from the Guarantor, any other
guarantor or any other Person by virtue of any action or proceeding or set
off or application at any time in reduction of or in payment of the Debt
shall be deemed to modify, release or otherwise affect the liability of
Guarantor under this Guarantee. Notwithstanding any such payments received or
collected by the Lender in connection with the Debt, Guarantor shall remain
liable for the balance of the Guaranteed Obligations until the Debt is paid
in full. This Guarantee shall continue to be effective or be reinstated, as
the case may be, if at any time any payment of the Debt or any portion
thereof is rescinded or must otherwise be returned by the Lender upon the
insolvency, bankruptcy or reorganization of the Borrower or otherwise, all as
though such payment had not been made.

          Lender shall not be required to inquire into the powers of the
Borrower or any of its partners, managers or other agents acting or
purporting to act on its behalf, and monies, advances, renewals or credits
described in Section 1 hereof in fact borrowed or obtained from Lender in
professed exercise of such powers shall be deemed to form part of the debts
and liabilities hereby guaranteed, notwithstanding that such borrowing or
obtaining of monies, advances, renewals, or credits shall be in excess of the
powers of the Borrower, or of its partners, managers or other agents
aforesaid, or be in any way irregular, defective or informal.

          3.   Dealing with the Borrower and Others.

               (a)  The Guaranteed Obligations shall not be released,
discharged, limited or in any way affected by anything done, suffered or
permitted by Lender in connection with any monies or credit advanced by
Lender to the Borrower or any security therefor, including any loss of or in
respect of any security received by Lender from the Borrower or others. It is
agreed that Lender, without releasing, discharging, limiting or otherwise
affecting in whole or in part the Guaranteed Obligations and liabilities
hereunder, may, without limiting the generality of the foregoing:

                     (i) grant time, renewals, extensions, indulgences,
releases and discharges to the Borrower and any other Person guaranteeing
payment of or otherwise liable with respect to the Debt (each such Person, an
"Obligor");

                    (ii) take or abstain from taking security or collateral
from the Borrower or any Obligor or from perfecting security or collateral of
the Borrower or any Obligor;

                   (iii) accept compromises from the Borrower or any Obligor;

                    (iv) apply all monies at any time received from the
Borrower or any Obligor upon such part of the Obligations as Lender may see
fit; or

                     (v) otherwise deal with the Borrower or any Obligor as
Lender may see fit.

               (b)  Lender shall not be bound or obliged to exhaust recourse
     against the Borrower or any other Obligor or any security, guarantee,
     indemnity, mortgage or collateral it may hold or take any other action
     (other than make demand pursuant to Section 7 of this Guarantee) before
     being entitled to payment from the Guarantor hereunder; and

               (c)  Any account settled by or between Lender and the Borrower
     shall be accepted by the Guarantor as conclusive evidence that the
     balance or amount thereby appearing due to Lender is so due.

          4.   Subrogation. The Guarantor shall not exercise any right of
subrogation with respect to payments made to Lender hereunder until such time
as all indebtedness of the Borrower to Lender shall have been irrevocably
paid in full in cash. In the case of the liquidation, winding-up or
bankruptcy of the Borrower (whether voluntary or involuntary) or in the event
that the Borrower shall make an arrangement or composition with its
creditors, Lender shall have the right to rank first for its full claim and
to receive all payments in respect thereof until its claim has been paid in
full and the Guarantor shall continue to be liable to Lender for any balance
of the Guaranteed Obligations. The Guarantor, to the extent permitted by law,
irrevocably releases and waives any subrogation rights or right of
contribution or indemnity (whether arising by operation of law, contract or
otherwise) Guarantor may have against the Borrower or any Person constituting
the Borrower if and to the extent any such right or rights would give rise to
a claim under the U.S. Bankruptcy Code that payments to Lender with respect
to the Obligations constitute a preference in favor of Guarantor or a claim
under the Bankruptcy Code that any such preference is recoverable from
Lender.

          5.   Representations and Warranties.  The Guarantor hereby
represents and warrants to Lender that:

               (a)  the Guarantor is not insolvent (as such term is defined
     in the debtor/creditor laws of the State of New York), and Guarantor now

     debtor/creditor laws of the State of New York), or (ii) violate any
     provision of any requirement of law or contractual obligation of
     Guarantor and will not result in or require the creation or imposition
     of any lien on any of the properties or revenues of Guarantor pursuant
     to any requirement of law or contractual obligation of Guarantor.

               (c)  the Guarantor has all requisite power and authority to
     execute, deliver and perform its obligations under this Guarantee.

     performance by the Guarantor of its obligations hereunder does not and
     will not contravene, violate or conflict with any requirement of law,
     and does not and will not contravene, violate or conflict with, or
     result in a breach of or default under, the operating agreement of
     Borrower, or any contractual obligation to which Guarantor or its assets
     is or are subject, and does not require or result in the creation or
     imposition of any lien in favor of any Person other than Lender.

               (e)  the execution and delivery hereof and the performance by
     the Guarantor of its obligations hereunder does not and will not
     contravene, violate or conflict with, or result in a breach of or
     default under, any indenture, mortgage, deed of trust, ground lease,
     contract, assignment, agreement or other instrument to which the
     Borrower or the assets of the Borrower are subject.

               (f)  no consent of any other party (including, without
     limitation, any partner, or any creditor of the Guarantor or Borrower)
     is required that has not been obtained by the Guarantor.

               (g)  this Guarantee has been duly executed and delivered by
     Guarantor and is the legal, valid and binding obligation of Guarantor,
     enforceable against Guarantor in accordance with its terms, except as
     enforceability may be limited by applicable bankruptcy, moratorium,
     insolvency, reorganization or similar laws affecting creditors' rights
     generally.

          6.   Intentionally Omitted.

          7.   Demand for Payment: The Guarantor shall make payment of the
Guaranteed Obligations and other amounts payable by the Guarantor hereunder
forthwith after demand therefor is made by Lender to the Guarantor in

Borrower or any other Person, prior to demanding payment of the Guaranteed
Obligations from the Guarantor.
