        <footnote id="F3">1/4th of the shares subject to the option became vested and exercisable on the Exercisable Date set forth above, and 1/48th vested or will vest each month thereafter on the same day of the month subject to Dr. Zediker continuing to serve as a service provider to the Issuer through the applicable vesting date.</footnote>

        <footnote id="F5">100% of the shares subject to the option became vested and exercisable on the Exercisable Date set forth above.</footnote>
        <footnote id="F6">The option is held directly by Dr. Zediker's spouse. Dr. Zediker may be deemed to share voting and investment control over the option; however, Dr. Zediker disclaims beneficial ownership of the option except to the extent of his pecuniary interest therein.</footnote>
