Under a make-whole provision in the Subscription Agreement, the Issuer agreed to adjust the price for the Units by issuing additional shares of Common Stock to the Reporting Person on June 23, 2025 in the event that the Issuer VWAP during the period from September 25, 2024 through June 21, 2025 is less than $10.00. "Issuer VWAP" for this purpose means the average of the daily volume-weighted average prices of the Common Stock on Nasdaq for completed trading days, as reported on Bloomberg or, if not reported thereby, any other authoritative source.
