Explanation of Responses:
1. In connection with the closing of the Issuer's initial public offering on April 25, 2012, each share of Series A, Series B, Series C and Series F Preferred Stock automatically converted into 0.5 shares of Issuer's Common Stock, and each share of Series E Preferred Stock automatically converted into 0.502315 shares of Issuer's Common Stock, for no additional consideration, reflecting an adjustment following a 1-for-2 reverse stock split effected by the Issuer on April 2, 2012. All shares of Common Stock (including fractions thereof) issued upon conversion were aggregated. No fractional share was issued upon the conversion of any share or shares of Preferred Stock.

Mr. Feiber and Ms. Schoendorf disclaim beneficial ownership of the shares held by MDV except to the extent of any pecuniary interest therein.
3. Shares sold as part of the Issuer's initial public offering.
