Explanation of Responses:

Id	Content
F1	The option is immediately exercisable as of the grant date. 1/60th of the shares vest monthly after the vesting commencement date of April 23, 2013, subject to the Reporting Person's continuous service to the Issuer on each such date. Unvested shares are subject to acceleration upon the occurrence of certain events. Unvested shares exercised are subject to a right of repurchase in favor of the Issuer should the Reporting Person cease to provide continuous service.
F2	This amendment is solely being filed to correct the original Form 4 filed on June 2, 2021 (the "Original Form 4"). The Original Form 4 reported the exercise, and subsequent sale, of 9,360 shares of common stock. The reporting person's broker administering the Rule 10b5-1 trading plans for the reporting person has advised the reporting person that the June 1, 2021 transactions listed on the Original Form 4 were executed by the broker in error. The broker has unwound these transactions through the broker's error account. Therefore, the transactions did not occur for purposes of the reporting person's account. We are reporting the corrected number of the shares underlying the relevant stock option beneficially owned by the reporting person. The transactions reported on the Original Form 4 did not result in a net change of the reporting person's common stock holdings. The reporting person held 85,321 shares of common stock as of June 1, 2021.
