Explanation of Responses:

1. Adjusted to reflect the 1-for-5 reverse stock split that occurred on July 11, 2014.

2. The options vest 1/3 on 7/11/2014, and the remaining 2/3 will vest in equal installments on the first and second anniversaries after 7/11/2014.

3. This award was canceled by mutual agreement of the reporting person and the Company in consideration of options granted on July 10, 2014.

4. The options vest 1/3 on 1/15/2015, and the remaining 2/3 will vest in equal installments on the first and second anniversaries after 1/15/2015.

5. The options vested 1/3 on 1/15/2013, and the remaining 2/3 will vest in equal installments on the first and second anniversaries after 1/15/2013.

6. The options vested 1/3 on 12/22/2010, and the remaining 2/3 will vest in equal installments on the first and second anniversaries after 12/22/2010.

7. Each restricted stock unit represents a contingent right to receive one share of the Issuer's common stock.

8. The restricted stock units vest in four equal amounts (25% each) as follows: 25% on the date of grant and 25% when the 20 trading day volume weighted average price of the Issuer's common stock equals or exceeds $20,75, $27.75 and $30.75. The unvested restricted stock units expire on June 30, 2016 if a vesting threshold has not been met by that date.

9. Upon the immediate vesting on April 5, 2013 of 10,000 restricted stock units granted to the reporting person on April 5, 2013, the reporting person elected to defer the receipt of those 10,000 shares of common stock, resulting in the accrual to his phantom stock account of 10,000 shares of phantom stock.

10. Each share of phantom stock represents the right to receive one share of the Issuer's common stock.

11. The phantom stock becomes payable on the earliest to occur of (a) termination of employment, (b) a change in control of the Issuer, or (c) April 1, 2015.
