Explanation of Responses:

( 1 )The reporting person is the Manager of JCMWZ, LLC. The reporting person disclaims beneficial ownership of these securities except to the extent of his pecuniary interest therein. ( 2 )Due to an unintentional scrivener's error, the total reported in Box 5 on the Reporting Person's Form 4 filed May 13, 2025 incorrectly reported ownership of 49,542 shares. This amendment corrects this error. ( 3 )The reported price is a weighted average purchase price. These shares were purchased in multiple transactions at prices ranging from $11.64 to $11.74 per share. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within the range set forth in this footnote. ( 4 )Total shares beneficially owned reduced from 408,155 shares reported on June 20, 2023 to 68,026 due to a 1-6 reverse stock split on September 26, 2023. ( 5 )Reporting Person, as VP-Investments of THRC Holdings, LP, a Texas limited partnership ("THRC") may be deemed to exercise voting and investment power over the Issuer's Class A common stock directly owned by THRC, and therefore, may be deemed to beneficially own such shares. THRC directly holds the securities of the Issuer. Reporting Person disclaims beneficial ownership of all equity securities reported herein except to the extent of its respective pecuniary interest therein, and the filing of this Form 4 shall not be construed as an admission that any such Reporting Person is the beneficial owner of any equity securities covered by this Form 4. ( 6 )The reported price in Column 4 is a weighted average purchase price. These shares were purchased in multiple transactions at prices ranging from $12.02 to $12.62 per share.
