Preliminary Statements

        The Borrowers, the Lenders, and the Agent are parties to a Loan and Security Agreement dated as of May 17, 2002, (as heretofore amended, the "Loan Agreement"; terms defined in the Loan Agreement (and not otherwise defined herein) are used in this Amendment as defined in the Loan Agreement).

        The Borrowers have requested that the Loan Agreement be modified to temporarily increase the Revolving Credit Facility from $30 million to $35 million.

        The Agent and Lenders have agreed to the aforementioned modification subject to the provisions of this Amendment.

Statement of Agreement

        Accordingly, in consideration of the Loan Agreement, the Loans made by the Lenders and outstanding thereunder, the mutual promises hereinafter set forth and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

        1.     Amendment to Loan Agreement.    Effective as provided in Section 2 of this Amendment, the Loan Agreement is hereby amended as follows:

        by amending Section 1.1 Definitions by amending the following definitions in their entirety to read as follows:

        "Revolving Credit Commitment" means as to FCC, $30,000,000 (or the principal amount of the then applicable Revolving Credit Facility, if greater), and, as to each Lender from and after an assignment by FCC, the amount set forth for such Lender in the Register maintained by the Agent pursuant to Section 13.1(d), representing such Lender's aggregate obligation, upon and subject to the terms and conditions of this Agreement, to make Revolving Credit Loans to each of the Borrowers.

        "Revolving Credit Facility" means the principal amount of $30,000,000; provided however, that the Revolving Credit Facility shall mean the principal amount of $35,000,000 during the period from the first date that a Borrower requests a borrowing that would cause the Revolving Credit Loans plus the Letter of Credit Obligations then outstanding to exceed $30,000,000 through the first to occur of the ninetieth (90th) day following such date or June 30, 2004.

        2.     Effectiveness of Amendment.    This Amendment shall be effective as of the first date on which the Agent has received each of the following, each in form and substance satisfactory to the Agent (the "Effective Date"):

        (a)   four (4) copies of this Amendment duly executed and delivered by each Borrower and the Lender; and

        (b)   such other agreements, certificates, instruments and other documents as any Lender through the Agent may reasonably request in connection with the transactions contemplated hereby.

        3.     Representations and Warranties.    Each Borrower hereby represents and warrants to the Agent and the Lender that it has the corporate or other power and has taken all actions necessary to authorize it to execute and deliver this Amendment and the other documents contemplated to be delivered by it pursuant to this Amendment and to perform its obligations under the Loan Agreement as amended by this Amendment and under such other documents; that this Amendment has been and each such other document when executed and delivered by such Borrower will have been, duly executed and delivered by such Borrower; and that the Loan Agreement as amended hereby and each such other document, constitute legal, valid and binding obligations of each Borrower, enforceable against each Borrower in accordance with their respective terms.

        4.     Effect of Amendment.    From and after the effectiveness of this Amendment, all references in the Loan Agreement and in any other Loan Document to "this Agreement," "the Loan Agreement," "hereunder," "hereof" and words of like import referring to the Loan Agreement, shall mean and be references to the Loan Agreement as amended by this Amendment. Except as expressly amended hereby, the Loan Agreement and all terms, conditions and provisions thereof remain in full force and effect and are hereby ratified and confirmed. The execution, delivery and effectiveness of this Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of any Lender or the Agent under any of the Loan Documents, nor constitute a waiver of any provision of any of the Loan Documents.

        5.     Counterpart Execution; Governing Law; Costs and Expenses.

        (a)   Execution in Counterparts.    This Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which taken together shall constitute but one and the same agreement. Delivery of an executed signature page of any party hereto by facsimile transmission shall be as effective as delivery of a manually executed counterpart thereof.

        (b)   Governing Law.    This Amendment shall be governed by and construed in accordance with the laws of the State of Georgia.

        (c)   Expenses.    In furtherance and not in limitation of the provisions of the Loan Agreement, the Borrowers will pay or reimburse the Agent and the Lenders for their costs and expenses, including reasonable fees and disbursements of counsel actually incurred, in connection with the preparation and delivery of this Amendment.
