        <footnote id="F2">Includes 7,500 shares of common stock that are subject to a right of repurchase by the issuer that lapses over time in accordance with the terms of a stock option award that was early exercised by the reporting person.</footnote>
        <footnote id="F3">The option vests over 5 years at the rate of 1/5th of the total number of shares on the 12 month anniversary from the vesting commencement date (March 21, 2016), and the remaining shares vesting equal monthly installments thereafter for the remaining four years. The vesting conditions of the award were subsequently amended to accelerate the vesting date to the first day of the month and year that such vesting date would have otherwise occurred. The option includes an early exercise provision that allows the reporting person to exercise the option as to the unvested shares (in addition to the vested shares), subject to the issuer's right of repurchase of any unvested shares that lapses over the vesting period.</footnote>
        <footnote id="F4">The option vests over 5 years at the rate of 1/60th of the total shares on each monthly anniversary from the vesting commencement date of April 1, 2017. The option includes an early exercise provision that allows the optionee to exercise the option as to the unvested shares (in addition to the vested shares), subject to the issuer's right of repurchase of any unvested shares that lapses over the vesting period.</footnote>
