Explanation of Responses:

Id	Content
F1	Represents the acquisition of Common Stock from the vesting of one-third of the performance stock units ("PSUs") granted on January 27, 2024 upon achieving the $7.00 share price target (adjusted for dividends paid).
F2	Represents the withholding by the Issuer of shares of Common Stock (based on $6.77 per share, the closing stock price on October 25, 2024) to satisfy tax withholding obligations associated with the vesting of PSUs and the consequent issuance of Common Stock.
F3	PSUs represent contingent rights to receive Common Stock on a one-for-one basis. These PSUs vest as follows: (a) one-third of these PSUs vest if, during any period of 90 consecutive trading days during the three-year period beginning on the grant date (the "Performance Period"), the Issuer's Common Stock closing stock price (plus the per share value of any dividends issued during the measurement date) (the "Stock Price") is at or above $7.00, (b) one-third of these PSUs vest, if during any period of 90 consecutive trading days during the Performance Period, the Stock Price is at or above $8.00, and (c) one-third of these PSUs vest, if during any 90 consecutive trading days during the Performance Period, the Stock Price is at or above $9.00. On March 12, 2024, the Board of Directors of the Issuer declared a special dividend of $0.60 per share of Common Stock, and each applicable Stock Price hurdle was lowered by $0.60 accordingly.
