The accrued interest on the principal amount of the Notes shall be calculated at the rate of 6% per annum and shall be payable semi-annually in cash, subject to Section 6 hereof, or in shares of the Borrower’s common stock, par value $.001 per share (the “Common Stock”), at the option of the Borrower, as more fully set forth in Section 5 hereof.

b. This Agreement, the Notes, the Draw Down Notices (as defined in Section 4 hereof) and each other document which evidences and/or secures the Loans are hereinafter collectively rePferred to as the “Loan Documents.”

3. Term and Termination. Subject to Section 9 hereof, the aggregate principal amount of the outstanding Notes and all accrued and unpaid interest thereon and other sums owing hereunder and thereunder shall be due and payable on the earlier (the “Maturity Date”) of: (i) July 31, 2007, or (ii) the acceleration of the obligations as contemplated by this Agreement. The Maturity Date may be extended as agreed upon in writing between the parties.

4. Draw Down Terms and Procedures. The Borrower shall deliver to the Lenders an executed draw down notice in connection with each request for a Loan to be made by the Lenders under this Agreement in the form attached hereto as Exhibit B (a “Draw Down Notice”). The Draw Down Notice shall be delivered to the Lenders at least two (2) business days prior to the Lenders making any Loan hereunder. The Borrower shall not make any request for a Loan and the Lenders shall not be obligated to honor any request for a Loan pursuant to this Agreement if such request is for an amount exceeding $250,000 in any twenty-four (24) hour

period; provided, however, this limitation may be waived with the prior written consent of the Lenders. The right of the Borrower to issue a Draw Down Notice and request a Loan pursuant to this Agreement shall terminate on December 31, 2003, unless otherwise extended in writing by the Lenders, the Borrower and the Senior Lenders (as defined in Section 7 hereof) under the Senior Credit Facility (as defined in Section 7 hereof). Other than with the prior written consent of the Lenders, all Loans made to the Borrower pursuant to this Agreement shall be used solely to repurchase shares of the Borrower’s Common Stock in the open market or in private transactions. Upon the Lenders’ receipt of a Draw Down Notice, the Lenders shall make the Loan to the Borrower within two (2) business days of the date of receipt of such Draw Down Notice.

5. Repayment of Loans. Subject to the provisions of Section 6 hereof, the Borrower may, at its option, repay the principal amount under the Notes and any interest accrued thereon in cash, subject to Section 6 hereof, or in shares of Common Stock. In the event that the Borrower elects to repay any of the principal amount under the Notes or any interest accrued thereon in shares of Common Stock, the Borrower shall provide each of the Lenders with twenty (20) trading days prior written notice (the “Borrower’s Repayment Notice”) of its intention to make such payments in shares of Common Stock. The number of shares of Common Stock to be issued as payment of the principal amount under the Notes and any interest accrued thereon and upon a Triggering Event (as defined in Section 10 hereof) shall be an amount equal to the quotient of (a) aggregate principal amount of the Notes plus accrued and unpaid interest thereon to be paid in shares of Common Stock, divided by (b) ninety-two percent (92%) of the average of the Volume Weighted Average Prices (as defined below) of the Common Stock for the twenty (20) trading days immediately prior to the date of the Borrower’s Repayment Notice. For purposes of this Agreement, Volume Weighted Average Price shall mean the daily volume weighted average price (based on a trading day from 9:30 a.m. to 4:00 p.m. eastern time) of the Common Stock on The Nasdaq SmallCap Market or the OTC Bulletin Board as reported by Bloomberg Financial LP using the AQR function. If the Borrower elects to repay the outstanding principal amount of the Notes and accrued but unpaid interest thereon in shares of Common Stock, the Borrower represents and warrants that the shares of Common Stock shall be issued in a transaction exempt from registration in accordance with the Securities Act of 1933, as amended (the “Securities Act”). Notwithstanding any other provision in the Loan Documents, the Borrower shall not be obligated to issue any shares of Common Stock in repayment of the Loans and accrued interest thereon which, in the aggregate, would exceed 9.99% of the outstanding Common Stock as of the date of this Agreement.

c. ACCELERATION AND ENFORCEMENT OF SUBORDINATED CLAIMS. Each of the Subordinated Lenders agrees not to demand, accelerate, bring suit to collect or otherwise exercise or enforce any right or remedy in respect of the amounts due under the Subordinated Credit Facility and the Notes or commence or prosecute any action or proceeding thereon or otherwise exercise or enforce any right or remedy in respect of the amounts due under the Subordinated Credit Facility and the Notes, including any right or remedy that otherwise might be available to it in any Bankruptcy Case, unless the Senior Indebtedness outstanding under the Loan Documents has been declared immediately due and payable by the Senior Lenders or has otherwise become immediately due and payable.

iv. Each of the Subordinated Lenders agrees to execute and deliver to the Administrative Agent all such further reasonable instruments confirming the irrevocable authorizations referred to in the foregoing clause (C) as the Administrative Agent may reasonably request at any time.

v. Each of the Subordinated Lenders agrees not to initiate or prosecute, or encourage any other entity to initiate or prosecute, any claim, objection, action or proceeding (or vote any claim in a Bankruptcy Case which would have the effect of) challenging or objecting to the enforceability of the Senior Indebtedness, any liens or security interests securing the Senior Indebtedness, any claim or adequate protection rights granted or allowed by a bankruptcy court in favor of the Secured Parties, the terms of any proposed orders authorizing the use of cash collateral to which the holders of a majority in principal amount of the Senior Indebtedness consent, or the terms of any proposed debtor-in-possession financing to be provided by any Secured Party or otherwise supported by the holders of a majority in the principal amount of the Senior Indebtedness in a Bankruptcy Case.

g. FURTHER ASSURANCES. Each of the Subordinated Lenders, at its own cost, shall take any further action as the Senior Lenders or any agent thereof may reasonably request in order to carry out more fully the intent and purpose of these subordination provisions.

h. BINDING EFFECT; LEGENDS. This Agreement shall be a continuing agreement, shall be binding upon and shall inure to the benefit of the parties hereto from time to time and their respective successors and assigns, shall be irrevocable, and shall remain in full force and effect until the Senior Indebtedness shall have been indefeasibly paid in full in cash, the commitments under the Credit Agreement shall have been irrevocably terminated, all letters of credit issued pursuant to any Loan Document shall have expired or terminated and the Interest

Parent and each holder of Subordinated Claims represents, warrants and agrees that the following legend will be and shall at all times remain placed conspicuously upon the face and signatures pages of the Notes and each other instrument evidencing any Subordinated Claim held by such holder:

“The indebtedness and all obligations evidenced or represented hereby, and certain other subordinated claims, are postponed, subordinated and junior in right of payment to Senior Indebtedness, as defined in and on the terms set forth in the Subordination Agreement dated as of June 13, 2003, executed and delivered for the benefit of the holders of such Senior Indebtedness by the maker hereof, Deutsche Bank AG New York Branch, and certain other signatories thereto. The provisions of said agreement are hereby incorporated herein, as if set forth at length herein and a copy of said agreement will be provided by Parent upon request.”

Parent agrees that neither Parent nor any of its subsidiaries shall at any time issue any promissory note in substitution, replacement or exchange for the Notes or any such other instrument, and (notwithstanding any contrary agreement enforceable by any holder of Subordinated Claims) neither Parent nor any of its subsidiaries shall be obligated to issue any such promissory note or other instrument, except only a promissory note that has such legend likewise placed thereon.

i. SUBROGATION. No payment or distribution to any holder of Senior Indebtedness pursuant to the provisions hereof shall entitle the Subordinated Lenders to exercise any right of subrogation in respect thereof until the indefeasible payment in full in cash of all Senior Indebtedness, the termination of all commitments under the Credit Agreement, the termination of all Interest Rate Agreements (as defined in the Credit Agreement) to which any Secured Party is a party, and the termination or expiration of each letter of credit issued by any Secured Party pursuant to the terms of any Loan Document.
