               compliance with the above-described covenant as of all other
               dates and (2) shall not limit or impair the Bank's right to
               demand strict performance of these covenants as of all other
               dates and (3) shall not limit or impair the Bank's right to

affirms and reaffirms that notwithstanding the terms of the Loan Agreement to
the contrary, (i) that the definition of "Code", "UCC" or "Uniform Commercial
Code" as set forth in the Loan Agreement shall be deemed to mean and refer to
"the Uniform Commercial Code" as adopted by the State of California, as may be
