Explanation of Responses:

Such vesting may be accelerated in connection with a Change in Control (as defined in the Issuer's Omnibus Incentive Compensation Plan). ( 2 )Reflects the previous transfer by the Reporting Person of 5,833 shares of Class A common stock to Argonaut 22 LLC at the Reporting Person's election. ( 3 )The shares are owned directly by Argonaut 22 LLC. Spinnaker Capital LLC is the Managing Member of Argonaut 22 LLC and the Reporting Person, a director of the Issuer, is the Managing Member of Spinnaker Capital LLC.
