On July 10, 2026, the Registrant entered into inducement offer letter agreements with certain Reporting Persons, pursuant to which such Reporting Persons agreed to exercise for cash all of their outstanding warrants at the current exercise price of $0.35 per share in consideration for the Registrant's agreement to issue, in a private placement, new unregistered common stock purchase warrants (the "New Warrants"). The Registrant is required to obtain stockholder approval ("Inducement Stockholder Approval") for the issuance of the shares of common stock underlying the New Warrants. The New Warrants will be exercisable beginning on the date Inducement Stockholder Approval is received at an exercise price of $0.35 per share and will expire on the five-year anniversary of the date Inducement Stockholder Approval is received. On July 10, 2026, the Registrant issued warrants to purchase 374,330 shares of Common Stock (the "Solicitation Agent Warrants") to ThinkEquity LLC in connection with a Solicitation Agreement, dated June 25, 2026. The Solicitation Agent Warrants have terms substantially similar to the New Warrants, including with respect to exercise price, expiration and term. ThinkEquity LLC distributed 141,462 Solicitation Agent Warrants to Mr. Stern. On June 10, 2026, Sanitam Parnters LLC ("Sanitam") distributed its holdings in the Registrant's preferred stock and warrants to its members. A.K.S. Family Partners LP received a portion of such distribution. As such Sanitam no longer beneficially owns any securities of the Registrant. The Series C Convertible Preferred Stock of the Registrant is perpetual and has no expiration date. /s/ Adam K. Stern 2026-08-13
