Explanation of Responses:
1. Represents shares withheld for payment of tax liability as a result of the vesting of restricted stock units, which was not included in the original report due to an administrative error.
2. Represents shares withheld for payment of tax liability as a result of the vesting of restricted stock units.
Remarks:
This amendment is being filed to amend the original Form 4 to report an additional 2,867 shares that were withheld to pay withholding taxes upon the vesting of restricted stock units, but were not included in the original Form 4 due to an administrative error. The Schedule 13G (Amendment No. 11) filed by the reporting person on February 11, 2021 correctly reported his share ownership (taking into account the 2,867 shares withheld but not previously reported on the Form 4).
