    NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto hereby covenant and agree to be bound as follows:

    Section 1.  Capitalized Terms.  Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to them in the Financing Agreement, unless the context shall otherwise require.

    Section 2.  Amendments.  The Financing Agreement is hereby amended as follows:

    2.1  The Advances.  Section 2.1 of the Financing Agreement is amended in its entirety as follows:

    Section 2.1  The Advances.  On the terms and subject to the conditions hereof, at the Borrower's request, the Lender, in its absolute and sole discretion and without any commitment to do so, may make the following Advances available to the Borrower:

    2.1(a)  up to seventy-five percent (75%) of the net amount of Eligible Accounts which are listed in the Borrower's most current Borrowing Base Certificate and which are deemed eligible for advances by the Lender, or such greater or lesser percentage at the Lender's sole and absolute discretion (the "Accounts Advances") not to exceed however the maximum amount of Two Million Five Hundred Thousand and no/100 Dollars ($2,500,000);

    2.1(b)  up to thirty percent (30%) of the net amount of Eligible Inventory of finished goods which is listed in the Borrower's most current Borrowing Base Certificate and which is deemed eligible for advances by the Lender, or such greater or lesser percentage at the Lender's sole and absolute discretion, not to exceed a maximum amount of $500,000 (the "Inventory Advances");

    Notwithstanding the preceding clauses 2.1(a),and 2.1(b), the maximum aggregate amount advanced from time to time shall not exceed $2,500,000.

    At the Borrower's request, Lender may in its sole and absolute discretion issue letters of credit, not to exceed a maximum amount of $410,000 in the aggregate. Any such issued letter of credit shall reduce the available amount of Accounts Advances by the amount of any issued letter(s) of credit. Borrower agrees to pay Lender any amounts paid by Lender on any such letters of credit. In addition to the Letter of Credit Fee, Borrower also agrees to pay Lender's customary charges for issuing such letters of credit and to reimburse Lender for any cost and expenses it incurs in connection with any such guarantee.

    Loans for additional sums requested by the Borrower may be made at the Lender's sole discretion based upon the Lender's valuation of the Borrower's collateral or other factors. The Borrower acknowledges and agrees that the Lender may from time to time, for the Lender's convenience, segregate or apportion the Borrower's collateral for purposes of determining the amounts and maximum amounts of Advances which may be made hereunder. Nevertheless, the Lender's security interest in all such collateral, and any other collateral rights, interests and properties which may now or hereafter be available to the Lender, shall secure and may be applied to the payment of any and all Advances and other indebtedness secured by the Lender's security interest, in any order or manner of application and without regard to the method by which the Lender determines to make Advances hereunder.

    2.2  Letter of Credit Fee.  Section 2.9 of the Financing Agreement is amended in its entirety as follows:

    Section 2.9  Letter of Credit Fee.  The Borrower shall pay to the Lender an annual fee in an amount equal to one percent (1%) of the maximum aggregate amount of the letters of credit ($4,100) (the "Letter of Credit Fee"). The initial Letter of Credit Fee shall be paid in full by February 19, 1998. The next Letter of Credit Fee shall be payable on June 27, 1998 and subsequent Letter of Credit Fees shall be payable on each June 27 thereafter.
