The amount of Obligations owed by Borrower to Foothill pursuant toSection 2.1is greater than the
limitations set forth inSection 2.1and, pursuant toSection 2.5, constitutes an
Overadvance as of July 20, 2001. Borrower has failed to immediately pay to Foothill, in cash, the amount of the excess constituting an Overadvance. This failure is in violation of Section 2.5of the Agreement and constitutes an Event of Default underSection 8.3of the
Agreement.
