Explanation of Responses:

1. The Series A Preferred Stock was automatically converted into Common Stock on a 6.986-for-1 basis upon the closing of the Issuer's initial public offering without payment of further consideration and had no expiration date.

2. These securities are held of record by Alta Partners VIII, L.P. ("APVIII"). Alta Partners Management VIII, LLC ("APMVIII") is the general partner of APVIII. Guy Nohra, Daniel Janney and Farah Champsi are managing directors of APMVIII and exercise shared voting and investment power with respect to the shares owned by APVIII. Each of the reporting persons disclaims beneficial ownership of such securities, except to the extent of his or its proportionate pecuniary interest therein. Mr. Janney, as a director of the Issuer, files Section 16 reports separately.

3. Upon the closing of the Issuer's initial public offering, this warrant to purchase shares of Series A Preferred Stock automatically converted on a 6.986-for-1 basis into a warrant to purchase shares of Common Stock, and the exercise price automatically adjusted accordingly. The transaction is listed solely for the purpose of reporting the change in the shares underlying the warrant and the change in exercise price.

4. The warrant is immediately exercisable.
