Footnotes

F1: Upon the closing of the Issuer's initial public offering, each share of Series A-3 Convertible Preferred Stock and Series B Convertible Preferred Stock (collectively, the "Preferred Stock") automatically converted into shares of the Issuer's common stock without payment or further consideration. There was no expiration date for the Preferred Stock. As a result of the Issuer's initial public offering, the reporting person is no longer a 10% owner of the Issuer and is therefore no longer subject to Section 16 in connection with its transactions in the equity securities of the Issuer.
