1.       DESCRIPTION OF EXISTING OBLIGATIONS: Among other amounts which may be
owing by Seller to Buyer, Seller is indebted to Buyer pursuant to, among other
documents, a Restated Non-Recourse Receivables Purchase Agreement, dated
September 25, 2001, by and between Seller and Buyer, as may be amended from time
to time, (the "Non-Recourse Receivables Purchase Agreement"). Capitalized terms
used without definition herein shall have the meanings assigned to them in the
Non-Recourse Receivables Purchase Agreement.

Hereinafter, all obligations owing by Seller to Buyer shall be referred to as
the "Obligations" and the Non-Recourse Receivables Purchase Agreement and any
and all other documents executed by Seller in favor of Buyer shall be referred
to as the "Existing Documents."

2.       DESCRIPTION OF CHANGE IN TERMS.

         A.       Modification(s) to Non-Recourse Receivables Purchase
                  Agreement:

                  The second paragraph under Section 2.1 entitled "Sales and
                  Purchase" is hereby amended to read as follows:

                  Each purchase and sale is at Buyer and Seller's discretion.
                  Buyer will not (i) pay Seller an aggregate outstanding amount
                  exceeding $12,500,000.00 or (ii) buy any Purchased Receivable
                  after April 1, 2003 (the "Maturity Date"). Each purchase and
                  sale will be on an assignment form acceptable to Buyer.

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

4.       NO DEFENSES OF SELLER. Seller agrees that, as of this date, it has no
defenses against the obligations to pay any amounts under the Obligations.

5.       PAYMENT OF LOAN FEE. Seller shall pay to Buyer a fee in the amount of
Two Thousand Five Hundred and 00/100 Dollars ($2,500.00) (the "Loan Fee") plus
all out-of-pocket expenses, for increasing and extending the line.

6.       CONTINUING VALIDITY. Seller understands and agrees that in modifying
the existing Obligations, Buyer is relying upon Seller's representations,
warranties, and agreements, as set forth in the Existing Documents. Except as
expressly modified pursuant to this Non-Recourse Receivables Purchase
Modification Agreement, the terms of the Existing Documents remain unchanged and
in full force and effect. Buyer's agreement to modifications to the existing
Obligations pursuant to this Non-Recourse Receivables Purchase Modification
Agreement in no way shall obligate Buyer to make any future modifications to the
Obligations. Nothing in this Non-Recourse Receivables Purchase Modification
Agreement shall constitute a satisfaction of the Obligations. It is the
intention of Buyer and Seller to retain as liable parties all makers and
endorsers of Existing Documents, unless the party is expressly released by Buyer
in writing. No maker, endorser, or guarantor will be released by virtue of this
Non-Recourse Receivables Purchase Modification Agreement. The terms of this
paragraph apply not only to this Non-Recourse Receivables Purchase


                                       1

Modification Agreement, but also to any subsequent Non-Recourse Receivables
Purchase modification agreements.

7.       CONDITIONS. The effectiveness of this Non-Recourse Receivables Purchase
Modification Agreement is conditioned upon payment of the Loan Fee.

8.       COUNTERSIGNATURE. This Non-Recourse Receivables Purchase Modification
Agreement shall become effective only when executed by Seller and Buyer.
