PRELIMINARY STATEMENT 1. The Bank issued and the Borrowers accepted and agreed to a Commitment Letter dated August 16, 1993 as amended by a First Amendment to Commitment Letter dated as of December 31, 1993 (the "Commitment Letter") pursuant to which the Bank agreed to make available to the Borrowers a working capital line of credit in a principal amount up to $5,000,000. Unless otherwise defined herein, capitalized terms used herein shall have the same respective meanings as set forth in the Commitment Letter. 2. The Borrowers and the Bank acknowledge and agree that Events of Default have occurred and currently exist under the Commitment Letter because the Borrowers are in breach of financial covenants with respect to minimum quick ratio, minimum profitability, maximum leverage and minimum capital base as set forth in Paragraphs 21, 22, 23 and 24 respectively, of Schedule II to the Commitment Letter (the "Existing Defaults"). As a result of, inter alia, the Existing Defaults, the Bank is entitled to enforce its remedies under the Commitment Letter and is not required to make any further advances under the Commitment Letter.
