Explanation of Responses:

1. Corrects an administrative error in the original Form 4 reporting that the purchase of 5,000 shares of common stock at $7.48 per share on 08/30/11 were directly held by the Reporting Person. Such shares purchased were in fact 4,636 shares of common stock at $7.49 per share, and are held indirectly by the Reporting Person's daughter. The number of shares of common stock held directly by the Reporting Person has been adjusted, accordingly, to reflect the change in indirect ownership reported.

2. The Reporting Person disclaims beneficial ownership of these securities.

3. Corrects an administrative error in the original Form 4 which did not include the purchase of 211 shares of common stock on 09/01/11 for the benefit of, and held indirectly by, the Reporting Person's daughter.

4. The option vested in two equal annual installments beginning on 11/22/2008.

5. The option vests in three equal annual installments beginning on 11/3/2009.

6. The option vests in three equal annual installments beginning on 11/10/2010.
