Explanation of Responses:

Id Content
F1 The reported sales were to cover taxes upon the vesting of restricted stock units, as required by the Company's equity incentive plan.
F2 On February 2, 2021, the reporting person was granted a target of 11,580 shares of restricted stock units, with the right to earn up to 300% of the target shares, subject to satisfaction of pre-determined, performance-based vesting criteria. On February 7, 2023, the Company's Compensation Committee of the Board of Directors determined and approved the achievement of the performance criteria for the restricted stock units, which resulted in 23,160 additional shares being earned by the reporting person. Of the 34,740 restricted stock units that were awarded, 17,370 will vest immediately and 17,370 will vest quarterly in the next two years.
