F1: Restricted stock units convert into shares of common stock on a one-for-one basis.

F2: The Reporting Person received 7,434 shares of common stock upon vesting of the restricted stock units, as reported in this Form 4. The Reporting Person forfeited 2,917 shares of common stock underlying the vested and outstanding restricted stock units to cover tax withholdings, using the market price of the Issuer's common stock at the time of forfeiture.

F3: The restricted stock units ("RSUs") were scheduled to vest over three years, with 1/3 of the RSUs vesting following the one-year anniversary of the date of grant, and the remaining RSUs vesting in four equal installments, commencing six months after the one-year anniversary of the date of grant and every six months thereafter until fully vested, provided that grantee is still employed on each such vesting date. In connection with the termination of the Reporting Person's employment as President and CEO of the Issuer, vesting of 7,434 RSUs was accelerated and the remaining RSUs were automatically forfeited as of the date of such termination.
