Explanation of Responses:

Id Content
F1 This forfeiture of shares for tax withholding purposes relates to the vesting in May 2024 of 4 service vesting restricted stock units granted to the executive in May 2020, 2021, 2022 and 2023. As agreed with the executive, the shares issued to the executive on those vesting events were reduced by a number of shares to cover the executive's tax withholding obligation with respect to the vested restricted stock units. However, the number of shares withheld on the vesting dates was insufficient to cover a Massachusetts income tax surcharge applicable to the executive, so additional shares have been withheld to cover the shortfall, as reported herein.
F2 Represents the closing price of the common stock on the date prior to the tax withholding.
F3 Of the shares held after this forfeiture event on June 5, 2024, 50,594 were issuable on vesting of restricted stock units granted to the reporting person under the 2012 Equity Incentive Plan and are subject to forfeiture.
