Explanation of Responses:

Id	Content
F1	The original Form 4, filed on June 4, 2025, is being amended by this Form 4 amendment to reflect that the grant previously reported was a grant of options instead of an award of shares of restricted stock.
F2	The option agreement provides that the option becomes exercisable in three equal annual installments over three years beginning on the first anniversary of the option's grant date. The option was granted on May 22, 2025.
