agreements contained herein, and subject to the terms and conditions hereof,
Borrowers and Lender hereby agree as follows:

     1.  DEFINITIONS. All capitalized terms used but not elsewhere defined

Credit Agreement.

     2.  AMENDMENTS TO CREDIT AGREEMENT. The Credit Agreement is amended as
follows:

     2.01  The definition of "Overadvance Amount" appearing in Section 1.1 of

amount of each Loan for the period commencing on the date thereof until such
Loan is paid in full, at a rate per annum determined by reference to the
Prime Rate or the LIBOR Rate, respectively. The applicable basis for
determining the rate of interest shall be selected by Borrowers at the time a
borrowing is requested pursuant to SECTION 2.3 or at the time a Notice of

interest at a rate determined by reference to the Prime Rate. Subject to

Overadvance as computed and determined from time to time and (ii) three
percent (3%) for all Loans greater than the Borrowing Base MINUS the Special
Overadvance as computed and determined from time to time, or (b) if it is a
LIBOR Rate Loan, then at the sum of the LIBOR Rate for the applicable
Interest Period PLUS three percent (3.0%)."

     2.03.  Section 4.2 of the Credit Agreement is hereby amended by
inserting a comma after the phrase "Prime Rate Loans" appearing therein.
