     A.   MODIFICATION(S) TO LOAN AGREEMENT

          1.   Effective as of the date this Loan Modification Agreement is
               entered into, Sub-letter (a) under Section 2.3 entitled
               "Revolving Line Interest Rates, Payments" is hereby amended to
               read as follows:

               (a) Interest Rate. Advances made under the Committed A/R
               Revolving Line accrue interest on the outstanding principal
               balance at a per annum rate of one percentage point above the
               Prime Rate. After an Event of Default, Obligations accrue
               interest at 5 percent above the rate effective immediately before
               the Event of Default. The interest rate increases or decreases
               when the Prime Rate changes. Interest is computed on a 360 day
               year for the actual number of days elapsed.

          2.   The following defined term under Section 13.1 entitled
               "Definitions" is hereby amended to read as follows:

               "Revolving Maturity Date" is April 19, 2003.

4.   CONSISTENT CHANGES. The Existing Loan Documents are hereby amended wherever
necessary to reflect the changes described above.

5.   NO DEFENSES OF BORROWER. Borrower (and each Pledgor signing below) agrees
that, as of the date hereof, it has no defenses against paying any of the
Obligations.

6.   PAYMENT OF LOAN FEE. Borrower shall pay Bank a fee in the amount of Eleven
Thousand Two Hundred Fifty Dollars ($11,250) ("Loan Fee") plus all out-of-pocket
expenses.

7.   CONTINUING VALIDITY. Borrower (and each Pledgor signing below) understands
and agrees that in modifying the existing Indebtedness, Bank is relying upon
Borrower's representations, warranties, and agreements, as set forth in the
Existing Loan Documents. Except as expressly modified pursuant to this Loan
Modification Agreement, the terms of the Existing Loan Documents remain
unchanged and in full force and effect. Bank's agreement to modifications to the
existing Obligations pursuant to this Loan Modification Agreement in no way
shall obligate Bank to make any future modifications to the Obligations. Nothing
in this Loan Modification Agreement shall constitute a satisfaction of the
Obligations. It is the intention of Bank and Borrower to retain as liable
parties all makers and endorsers of Existing Loan Documents, unless the party is
expressly released by Bank in writing. Unless expressly released herein, no
maker, endorser, or guarantor will be released by virtue of this Loan
Modification Agreement. The terms of this paragraph apply not only to this Loan
Modification Agreement, but also to all subsequent loan modification agreements.

8.   CONDITIONS. The effectiveness of this Loan Modification Agreement is
conditioned upon payment of the Loan Fee.

     This Loan Modification Agreement is executed as of the date first written
above.
