### Footnotes:

(1) On March 23, 2022, Mr. Toler was granted a target of 21,919 performance stock units ("PSUs") under the Issuer's 2020 Equity Incentive Plan.  Each PSU represents the right, upon achievement of certain specified performance-based vesting criteria, to receive one share of the Issuer's common stock.  On January 17, 2023, the Compensation Committee of the Board of Directors determined that 25% of the performance-based conditions were met resulting in 5,480 PSUs earned by Mr. Toler. This transaction is late due to an inadvertent administrative error and not any error of Mr. Toler.

(2) Shares withheld to satisfy tax withholding obligation applicable to the vesting of 5,480 stock-settled PSUs, which may be settled, on a 1-for-1 basis, only in shares of common stock. Fractional amounts have been rounded to the nearest whole number.

(3) Shares withheld to satisfy tax withholding obligation applicable to the vesting of 6,666 stock-settled restricted stock units ("RSUs"), which may be settled, on a 1-for-1 basis, only in shares of common stock. Fractional amounts have been rounded to the nearest whole number.

(4) Shares withheld to satisfy tax withholding obligation applicable to the vesting of 31,766 stock-settled RSUs, which may be settled, on a 1-for-1 basis, only in shares of common stock. Fractional amounts have been rounded to the nearest whole number.
