Explanation of Responses:

Each such person disclaims any such beneficial ownership except to the extent of his pecuniary interest therein. ( 2 )As contemplated in connection with the initial public offering of the Issuer, 239,016 shares of common stock of the Issuer were returned by the reporting person to the Issuer for no consideration and cancelled because the underwriters' over-allotment option was not exercised in full.
