     D. General.
        -------

     1. Except as specifically provided herein, all terms and conditions of the

Borrowers acknowledge that except as specifically provided in this Amendment,
nothing in this Amendment shall affect Borrowers' obligations under the
Agreement, which obligations remain valid, binding and enforceable, or shall
constitute a waiver by Lender of any of Lender's rights or remedies, now or at

parties hereto on different counterparts), each of which shall constitute an
original, but all of which when taken together shall constitute a single

in the Agreement and reaffirm all covenants set forth therein. The Borrowers

provisions hereof, there exists no Event of Default as defined in the Agreement,
nor any condition, act or event which with the giving of notice or the passage
of time or both would constitute any such Event of Default.
