Explanation of Responses:

1. Represents shares of Common Stock acquired upon the automatic conversion of Series A convertible preferred stock upon the closing of the Issuer's initial public offering of Common Stock.

2. The Series A convertible preferred stock did not have an expiration date. The Series A convertible preferred stock automatically converted into shares of Common Stock at an effective conversion ratio of one-to-one upon the closing of the Issuer's initial public offering of Common Stock.

3. Represents shares of Common Stock acquired upon the automatic conversion of all principal and accrued interest due on these convertible promissory notes upon the closing of the Issuer's initial public offering of Common Stock at an effective conversion price of approximately $13.44.

4. These shares of Common Stock were acquired upon conversion of a convertible promissory note exempt from the definition of a derivative security because the conversion price of such securities did not become fixed until their automatic conversion at the time of closing of the Issuer's initial public offering of Common Stock.

5. Represents shares of Common Stock acquired upon the conversion of a convertible promissory note issued in December 2010. The outstanding principal amount and accrued but unpaid interest therein was automatically converted into shares of Common Stock upon the closing of the Issuer's initial public offering of Common Stock at an effective conversion price of $7.00 which represents the initial public offering price per share of the Common Stock sold by the issuer..
