F1	These shares are represented by restricted stock units (the "RSUs"). Each RSU represents a contingent right to receive one share of Common Stock of the Issuer. The RSUs will vest over a three year period at a rate of 33% on February 1, 2027, 33% on February 14, 2028 and 34% on February 12, 2029, subject to the Reporting Person's continuous service with the Issuer as of each such vesting date.
F2	The Issuer has adopted a "sell-to-cover" policy to satisfy the tax withholding obligations of the Reporting Person. The sales reported on this Form 4 represent the number of shares required to be sold by the Reporting Person to cover tax withholding obligations in connection with the vesting of restricted stock units. Such sales were automatic and not at the discretion of the Reporting Person.

Full information regarding the number of shares sold at each price shall be provided upon request to the staff of the U.S. Securities and Exchange Commission, the Issuer, or a security holder of the Issuer.
F4	Represents the weighted average sales price per share. The shares sold at prices ranging from $12.88 to $12.91 per share.
