Explanation of Responses:

( 1 )Thomas L. Walker, who is a director of the issuer, is the treasurer for the reporting person and serves on the issuer's board of directors as the reporting person's representative. In light of Mr. Walker's relationship with the reporting person, the reporting person may be deemed a "director by deputization" of the issuer for purposes of Section 16 of the Securities Exchange Act of 1934. This filing is therefore being made out of an abundance of caution, without taking any position as to whether the reporting person is in fact a director by deputization. Mr. Walker disclaims beneficial ownership of any securities of the issuer held by the reporting person, except to the extent of his pecuniary interest therein, if any. ( 2 )Distribution from Goff Jones Strategic Partners, LLC ("Goff Jones"), of which the reporting person is a member. Goff Jones no longer serves its original purpose and is being dissolved. Prior to its dissolution, Goff Jones distributed all of its Common Stock and warrants exercisable for Common Stock to its members. No securities of the issuer were sold by Goff Jones as part of the dissolution. ( 3 )The reporting person's beneficial ownership has been reduced to adjust for an overstatement of one share of Common Stock in a Form 4 filed on April 27, 2026. ( 4 )Represents the weighted average sale price of Common Stock purchased in a series of open market transactions on the transaction date at prices ranging from $0.4 to $0.4327 per share. ( 5 )The reporting person undertakes to provide, upon request by the staff of the Securities and Exchange Commission, the issuer, or a security holder of the issuer, full information regarding the number of shares purchased at each price. ( 6 )Prior to the dissolution of Goff Jones, the reporting person received a portion of the warrants held by Goff Jones exercisable for 205,716 shares of Common Stock.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
