Explanation of Responses:
1. These securities are held by Anthem Capital II, L.P. ("Anthem"). The general partner of Anthem is Anthem Capital Partners, LLC ("Anthem Partners"). Mr. Gust is a manager of Anthem Partners and may be deemed to share voting and dispositive power over the securities held by Anthem. Mr. Gust disclaims beneficial ownership of the securities, except to the extent of his pecuniary interest therein.
2. The shares underlying this option are fully vested.
3. The number of underlying shares of common stock and the exercise price reported reflect a 1-for-3.302 reverse stock split of the Issuer's common stock effected on October 25, 2013.
4. Mr. Gust received this option in his capacity as a director of the Issuer. The option is held for the benefit of Anthem Capital and may only be exercised at the direction of Anthem Capital. The net proceeds received from the exercise and sale of the shares, if any, would be remitted to Anthem Capital. Mr. Gust disclaims beneficial ownership of the shares underlying the option, except to the extent of his pecuniary interest therein.
5. Each share of Series A-1 Preferred Stock is convertible, at any time, at the holder's election, into the Issuer's common stock on a 1-for-3.302 basis. In addition, effective immediately prior to the closing of the Issuer's initial public offering of its common stock, each share of Series A-1 Preferred Stock will automatically convert into approximately 0.3028 shares of the Issuer's common stock. The Series A-1 Preferred Stock has no expiration date.
