The Reporting Person disclaims beneficial ownership over these shares of common stock, which are held directly by the UTMA, except to the extent of the Reporting Person's indirect pecuniary interest therein. | These shares are held by the Reporting Person's adult child. The Reporting Person disclaims beneficial ownership over these shares of common stock, which are held directly by the adult child of the Reporting Person. | At the Effective Time, each Issuer stock option for which the applicable exercise price was less than $13.00 (each, an "In-the-Money Option") that was outstanding immediately prior to the Effective Time became fully vested and exercisable and was canceled in exchange for the payment in cash equal to the product of (i) the total number of shares of common stock subject to such canceled In-the-Money Option immediately prior to the Effective Time and (ii) the excess of $13.00 over the exercise price per share subject to each such canceled In-the-Money Option, without interest.
