Explanation of Responses:
1. The Series C preferred stock was not initially convertible. Conversion of the shares of Series C preferred stock was subject to the approval of the Issuer's stockholders in accordance with the Listing Rules of the Nasdaq Stock Market. This approval was obtained on April 5, 2013 and resulted in the automatic conversion of the Series C preferred stock, including accrued dividends (which were converted into an additional 420,616 shares) into Common Stock. No payment or additional consideration was made for the Common Stock or received for the Series C preferred stock, other than cancellation of the Series C preferred stock and accrued dividends in exchange for the Common Stock.
2. All share numbers and exercise prices have been adjusted in this filing to take into account the 1 for 2 reverse stock split that was effective August 30, 2012.
