     B.   Guarantor is the general partner of Borrower.

     C.   As a condition precedent to Lender making the Original Loan to
Borrower, Guarantor executed and delivered that certain Foreclosure Guaranty

"Guaranty"; a copy of such Guaranty is attached hereto as Exhibit A).

     D.   The Original Loan matured on June 12, 1996 and has not been repaid.
In lieu of exercising its rights and remedies with respect to Borrower's failure
to repay the Original Loan when due, Lender agreed with Borrower to amend and
restate the various terms, conditions, covenants and provisions of the Original
Loan and its related documents.  The Original Loan, as so amended and restated,
is hereinafter referred to as the "Amended and Restated Loan".

     E.   Lender has agreed to amend and restate the Original Loan on the
condition that Guarantor duly execute and deliver this Reaffirmation in favor of
and for the benefit of Lender.

     NOW, THEREFORE, in consideration of the foregoing recitals and the mutual
covenants and promises herein and for other good and valuable consideration, the
receipt and adequacy of which are hereby conclusively acknowledged, Lender and
Guarantor agree as follows:

     1.   Guarantor hereby reaffirms the terms and provisions of the Guaranty.

     2.   Guarantor hereby covenants and agrees that, notwithstanding the
amendment and restatement of the Original Loan, the Guaranty shall remain in
full force and effect and guarantor's obligations thereunder shall apply to the
