    <exhibitInfo>Item 4: Information with respect to the Reporting Persons' ownership of the Common Stock as of May 15, 2025, is incorporated by reference to items (5) - (9) and (11) of the cover page of the respective Reporting Person.

The amount benefically owned by each Reporting Person includes 4,500,000 pre-funded warrants exercisable to common stock and subject to a 9.99% Beneficial Ownership Limitation.  The Issuer shall not effect any exercise of any Warrants, to the extent that, after giving effect to such attempted exercise, such Holder would be a benefical owner of Common Stock beneficially owned by the Holder for purposes of Section 13(d) or Section 16 of the Exchange Act and the applicable rules and regulations of the Commission would beneficially own a number of shares of Common Stock in excess of the Beneficial Ownership Limitation.

The amount beneficially owned by each Reporting Person is determined based on 150,484,182 Common Stock. Such amount is calculated using 145,984,182 Common Stock outstanding as of February 24, 2025, according to the issuer's Form 10-K filed with the SEC on February 27, 2025, as well as 4,500,000 pre-funded warrants.
