Explanation of Responses:

1. These shares are held in a trust for the benefit of the reporting person's spouse and children. The reporting person's spouse and nephew are trustees of the trust.

2. Each share of Series A Convertible Preferred Stock is convertible into Common Stock at any time and automatically converts into Common Stock on a 1-for-3.1345 basis immediately prior to the closing of the Issuer's initial public offering of Common Stock and has no expiration date. The number of underlying shares of Common Stock reported in Column 3 does not reflect this 1-for-3.1345 reverse stock split, pursuant to which each share of Series A Convertible Preferred Stock will become convertible into 0.3190 of a share of Common Stock.

Remarks:

This amendment is filed to report shares held in a trust for the benefit of the reporting person's spouse and children as an indirect holding of the reporting person. No other changes were made to the information reported on the original Form 3 filed on January 30, 2014.
