**Item 4. Purpose of Transaction**

Item 4 to Schedule 13D is hereby amended to include the following:

The disclosure under Item 3 in this Amendment is incorporated herein by reference.

**Item 5. Interest in Securities of the Issuer**

**(a)**
As of the date of this Schedule 13D, the Reporting Persons beneficially own 3,182,239 Shares, representing 33.7% of the outstanding Shares.

The Reporting Persons also beneficially own warrants representing the right to acquire up to an aggregate of 6,832,379 Shares, however, the exercise of such warrants are subject to a beneficial ownership limitation of 9.99% of the number of Shares outstanding immediately after giving effect to the issuance of the Shares issuable upon exercise of such warrants. If there was no 9.99% limit on the exercise of the warrants, the Reporting Persons would be deemed to be the beneficial owners of 10,014,618 Shares (including 6,832,379 Shares that would be issuable upon exercise of the warrants held by the Reporting Persons), representing 61.5% of the outstanding Shares.

The percentages used herein are based upon the 9,947,841 Shares reported to be outstanding as of May 12, 2026, by the Issuer in its Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on May 13, 2026.

**(b)**
The Reporting Persons have sole voting and dispositive power over 3,182,239 Shares.

**(c)**
Except as set forth in Item 3 and Item 4, the Reporting Persons have not effected any transaction in the Shares during the past sixty days.

**Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.**

Item 6 to Schedule 13D is hereby amended to include the following:

The disclosure under Item 3 and Item 4 in this Amendment is incorporated herein by reference.

The summaries contain herein of the Note Purchase Agreement and the form of Note, as applicable, are not intended to be complete and are qualified in their entirety by reference to the full text of Note Purchase Agreement and the form of Note, as applicable, copies of which are filed as exhibits hereto and which are incorporated by reference herein.
