Explanation of Responses:

Id Content
F1 Due to a clerical error related to the reporting of shares previously withheld by the Company to satisfy tax obligations upon the vesting of Restricted Stock Units, this number was previously overstated by 35 shares. This value reflects the adjustment, decreasing the amount beneficially owned by 35 shares.
F2 The options became exercisable based on the following vesting schedule: twenty five percent (25%) vested on the first anniversary of the grant date and an additional twelve and one half percent (12.5%) vested on each sixth month anniversary date thereafter through the fourth anniversary of the date of grant. All options are currently exercisable.
