     Whereas, the Obligors wish to prepay the Notes in full and are permitted to do so pursuant to Section 2.2 of the Note Agreement, provided that the Obligors pay interest accrued to the date of prepayment and a premium equal to the Make-Whole Amount, provided, further, that the Obligors wish to prepay the Notes together with interest accrued thereon, but without premium, except as provided below;

     Whereas, the Company wishes to redeem the Warrant and shall remit to the Investor an amount equal to $1,300,000, such amount to constitute satisfaction of the premium due pursuant to Section 2.2 of the Note Agreement and the redemption price of the Warrant;

     Whereas, the Company will derive substantial direct and indirect benefit from the waiver as provided in Section 7 hereof by the Investor of its right to receive the Make-Whole Amount pursuant to said Section 2.2 in connection with the prepayment in full of the Notes by the Obligors and as an inducement to the Investor to waive such right the Company has agreed to execute and deliver this Agreement to the Investor;
