     proceeding under any bankruptcy or insolvency laws commenced against the
     Borrower is dismissed within ninety (90) days.


     The "Maturity Date" shall mean the earlier to occur of (a) September 2,
2007 or (b) the date upon which the Borrower receives the proceeds of the sale

Lender and the Borrower shall constitute a waiver of the rights and remedies of
the Lender hereunder. No single or partial waiver by the Lender of any default
or right or remedy which it may have shall operate as a waiver of any other
default, right or remedy or of the same default, right or remedy on a future
occasion.
