WHEREAS, the Holder has agreed to forbear from exercising its Initial Repurchase Rights with respect to not less than 75% in aggregate principal amount of the Notes beneficially owned by the Holder as of the effective date of this Agreement, in consideration for the Company's purchase of 25% in aggregate principal amount of the Holder's Notes and the right to exercise a Repurchase Right on January 31, 2009.

NOW, THEREFORE, in consideration of the premises and the mutual covenants and provisions hereinafter contained, the parties hereto hereby agree as follows:

   1. In consideration of the agreements set forth in Section 2 hereto, the Company agrees to purchase from the Holder, and Holder agrees to sell to the Company, such number of Notes as shall equal 25% of the aggregate principal amount of the Holder's Notes (the "Purchased Notes") for a cash payment equal to $297.95 per $1,000 in aggregate principal amount of Notes (the "Cash Payment").

   2. The Company agrees that it shall pay Holder the Cash Payment for the Purchased Notes not later than Friday, May 23, 2008.

   3. In consideration for Holder's forbearance agreement set forth in Section 2, the Company agrees to issue Holder a warrant to purchase 25,000 shares of common stock of the Company for each $1,000,000 in aggregate principal amount of Notes deferred pursuant to Section 2.
