$40,000,000 outstanding under the Second Amended and Restated Loan Agreement
dated as of March 30, 2001 (collectively, the "LOAN AGREEMENT"), between the

particularly set forth herein.

         1. WAIVER AND DIRECTION. Subject to the terms and conditions set forth
in Section 3 hereof, and based upon information furnished by the Company to the

the assets and stock of the corporations whose stock is which are the subject of
the Stock Sale contemporaneously with the closing of the Stock Sale.

         2. AMENDMENT TO INTEREST RATE.

                  (a) Effective April 20, 2001, the Rate of interest payable
         under the Note will be the Note Interest Rate. As used herein, "NOTE
         INTEREST RATE" means, as of any date of determination, a rate per annum
         equal to (a) if such date is prior to April 20, 2001, the greater of:
         (i) 8.56% or (ii) the Prime Rate plus one and one-half percent (1.50%)
         and (b) if such date is on or after April 20, 2001, the greater of: (i)
         8.56% or (ii) the lesser of (A) the highest interest rate allowed by
         applicable law on the Note and (B) the Prime Rate PLUS one and one-half
         of one percent (1.50%) plus the Applicable Adjustment Margin as of such
         date."

         determination, an amount equal to the product of (a) one-half of one
         percent (0.50%) TIMES (b) the number of complete 30 consecutive day
         periods which shall have expired since April 20, 2001 as of such date
         of determination."
