(a) and (b) As of February 16, 2017, the Reporting Person beneficially owned 2,271,438 shares of Common Stock, which represents 6.9% of the outstanding shares of Issuer. This percentage is based upon 30,555,316 shares of Common Stock outstanding as reported on the Company’s Quarterly Report on Form 10-Q filed on November 14, 2016. Such shares of Common Stock include 2,255,438 shares of Common Stock issuable upon exercise of stock

options issued to the Reporting Person and exercisable within 60 days of February 16, 2017, 994,763 of which shares remained subject to vesting as of February 16, 2017. The Reporting Person has sole voting and dispositive power with respect to such shares of Common Stock.

(c) The Reporting Person has not effected any transaction in the Common Stock or other equity securities of Issuer during the past sixty days.

(d) Not applicable.

(e) Not applicable.

The Company granted options to purchase shares of Common Stock to the Reporting Person in connection with, and as an inducement to, the commencement and continuance of his employment with the Company. The options are immediately exercisable when they are granted, but shares underlying the options are subject to repurchase by the Company until they are vested. The option shares vest over four years of service, with 25% vesting upon completion of 12 months of service from the vesting commencement date, and the remainder vesting in 36 equal monthly installments thereafter. Such options may vest on an accelerated basis in connection with a change in control of the Company and certain terminations of the Reporting Person’s employment with the Company.

100% of the unvested portion of the options granted to the Reporting Person in connection with his services as the Company’s President and Chief Executive Officer will vest in full if the Company undergoes a change of control before his service with the Company terminates and, within twelve months after such change of control the Company (or the surviving corporation) terminates his employment for any reason other than cause or his permanent disability or if the Reporting Person terminates his employment for good reason. In addition, if the Company terminates the Reporting Person’s employment for any reason other than cause or his permanent disability or he terminates his employment for good reason, in each case prior to a change of control, then the vested portion of the Reporting Person’s option will be determined by adding 12 months to his actual service. Good reason and change of control in the Reporting Person’s stock option are defined as they are in his employment agreement.

The Employment Letter Agreement with the Reporting Person dated August 4, 2014 and the Stock Option Agreement with the Reporting Person granted on August 4, 2014 were filed as exhibits to the Company’s Quarterly Report on Form 10-Q filed on November 14, 2014 as exhibit numbers 10.1.1 and 10.1.2, respectively, and are incorporated herein by reference.
