2. 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.

3. The sales reported on this Form 4 were effected pursuant to a trading plan adopted by the Reporting Person's trust pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended.

4. Each share of Series A Convertible Preferred Stock was convertible into Common Stock at any time and automatically converted 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 had no expiration date.

5. The number of underlying shares of Common Stock reported in Column 7 reflects the automatic conversion of shares of Series A Preferred Stock into Common Stock on a 1-for-3.1345 basis immediately prior to the closing of the Issuer's initial public offering.

Remarks:

In addition to reporting a current indirect transaction by a trust holding shares for the benefit of the reporting person's spouse and children, this Form 4 also reports previously unreported historical transactions by the trust.
