Material Amendments to Convertible Notes:

1. The maturity date on the Converible Notes was extended from August 31, 2011 to October 31, 2011. $2.0 million of the principal is due and payable on September 9, 2011 and the remaining $10.5 million is due and payable on October 31, 2011. In exchange for the extension, the Company issued 500,000 shares of its common stock to the Lender (the "Extension Fee Shares"), and the conversion price under each of the Convertible Notes will be automatically adjusted on September 1, 2011 from $9.80 per share to $3.31 per share, which represents the closing price for a share of the Company's common stock on August 31, 2011.

2. The Company was given the right to prepay all or part of the Convertible Notes.

Material Amendments to Consent Fee Note:

1. The Company's right to satisfy payment demands using shares of its common stock was amended to provide that the Company can exercise such right to use shares of common stock as long as the volume weighted average price for a share of its common stock for the 3 consecutive trading day period prior to the date a payment demand is made (the "VWAP Price") is greater than $2.00. Prior to the execution of the Agreement, the Company could only satisfy payment demands using shares of its common stock if the share price was at least $10.00.

2. The Lender's right to make payment demands was amended so that no payment demands can be made prior to October 31, 2011 unless the Company's VWAP Price is greater than $2.00.

3. The Company was given the immediate right to prepay all or part of the Consent Fee Note (the "Call Right"). In the event the Company exercises its Call Right, the amount so called must be paid in cash. Prior to the execution of the Agreement, the Company could not call any part of the Consent Fee Note until January 16, 2012.

Other Material Terms:

1. The Agreement provides that under no circumstances can the Company issue to Lender on an aggregate basis, upon conversion of the Convertible Notes or in satisfaction of payment demands made under the Consent Fee Note, shares constituting more than 19.99% of the Company's issued and outstanding shares immediately prior to the execution of the Agreement ("Share Cap Limitation"). In the event that the Lender attempts to make a conversion under the Convertible Notes but is unable to effect all or part of such conversion because of the Share Cap Limitation, then the Company is obligated to pay Lender an amount in cash equal to the product of (a) the number of shares in excess of the Share Cap Limitation, and (b) the lesser of (i) the volume weighted-average price of the Company's common stock for the three consecutive trading days ending on the trading day immediately preceding the effective date of such conversion, and (ii) $4.50.
