AMENDMENTS TO EXISTING WARRANTS

This prospectus supplement is being filed to disclose the following:

On March 31, 2024, we entered into a warrant amendment agreement (the “Warrant Amendment Agreement”) with an institutional investor under which the Company agreed to amend certain outstanding warrants to purchase up to an aggregate of 800,000 shares of Common Stock that were previously issued in November 2022 with an exercise price of $0.3288 per share. In January 2023, the Existing Warrants’ exercise price was adjusted to $8.22 as a result of the Company’s reverse stock split.

Under the Warrant Amendment Agreement, with respect to Existing Warrants to purchase up to an aggregate of 800,000 shares of Common Stock held by an institutional investor, the Company agreed to (i) lower the exercise price of such Existing Warrants to $1.10 per share, (ii) provide that such Existing Warrants, as amended, will not be exercisable until the Company receives approval from its stockholders with respect to the issuance of shares of Common Stock issuable upon exercise of the amended Existing Warrants (such date, the “Stockholder Approval Date”) and (iii) extend the original expiration date of such Existing Warrants to be five (5) years following the Stockholder Approval Date. These amendments became effective on March 31, 2024.
