RECITALS

A.            Borrower and Lender have entered into that certain Loan and Security Agreement dated as of May 1, 2008, Amendment No. 1 to the Loan and Security Agreement dated as of November 19, 2008, Amendment No. 2 to the Loan and Security Agreement dated as of May 31, 2009, (as may be amended, restated, or otherwise modified, the “Loan Agreement”), pursuant to which Lender has agreed to extend and make available to Borrower certain advances of money.

B.            Borrower and Lender have entered into that certain Forbearance Agreement dated as of July 31, 2009, as amended by the Amendment to Forbearance Agreement, dated as of August 14, 2009, the Second Amendment to Forbearance Agreement dated as of August 20, 2009, the Third Amendment to Forbearance Agreement dated as of September 23, 2009 (as so amended, the “Forbearance Agreement”), pursuant to which Lender agreed to forbear from exercising its remedies under the Loan Agreement as a result of the Specified Default, subject to the terms and conditions, and for the period specified in the Forbearance Agreement.

C.            Pursuant to Section 7.23 of the Loan Agreement, Borrower was required to pay to Lender the remaining balance of the Restructuring Fee in the amount of $160,000 on the earliest of (i) September 30, 2009, (ii) the acceleration of the Secured Obligations, and (iii) payment in full of the Secured Obligations.  Borrower acknowledges that it has failed to make the required payment of $160,000 by such date and, as a result, an Event of Default (the “Specified Payment Default”) has occurred and is continuing under Section 9.2 of the Loan Agreement.
