Explanation of Responses:

Id	Content
F1	The reporting person is a managing principal of Castle Creek Capital VI LLC, the sole general partner of Castle Creek Capital Partners VI, LP ("Fund VI"). As of January 28, 2026, Fund VI no longer owns any shares of the Issuer's common stock (the "Fund VI Shares"), although Fund VI's prior ownership of 2,346,104 Fund VI Shares was reported in the Form 4 filed for the reporting person on February 5, 2026 (the "February 5 Form 4"). However, during the period that Fund VI owned such Fund VI Shares, the reporting person was not the beneficial owner of the Fund VI Shares for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose and expressly disclaims such beneficial ownership. This amendment is therefore being filed to remove the 2,346,104 Fund VI Shares and to remove the 3,725 shares that belong to Castle Creek Advisor IV LLC that were previously reported in Table I in the February 5 Form 4.
