The Reporting Persons will acquire 3,485,446 of the Shares reported owned herein in the Initial Closing (as defined in Item 4 below) pursuant to the 2025 Purchase Agreement (as defined in Item 4 below) in connection with the 2025 Private Placement (as defined in Item 4 below).

The aggregate purchase price of the 2,800,907 Shares and Warrants to purchase 5,601,814 Shares to be acquired by the SMAs in the Initial Closing pursuant to the 2025 Purchase Agreement is approximately $1,145,571. The source of funding for the transactions pursuant to which the Reporting Persons obtained ownership of the Shares referenced above was derived from the working capital of 325 Master Fund and the SMAs (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business). 101,207 of the Shares reported owned herein were granted to Mr. Friedberg in connection with his service as a director of the Issuer."

Item 4 is hereby amended to add the following: On October 24, 2025 (the "Subscription Date"), the Issuer entered into a Securities Purchase Agreement (the "2025 Purchase Agreement") with 325 and certain other accredited investors (collectively with 325, the "Investors"), pursuant to which, among other things, certain of the Reporting Persons agreed to purchase (i) 17,114,912 Shares at a purchase price of $0.409 per Share and (ii) warrants to purchase 34,229,824 Shares (the "Warrants") with an exercise price of $0.409 per Share as part of a private placement (the "2025 Private Placement"). Pursuant to the 2025 Purchase Agreement, the Issuer agreed to issue to the Investors, and the Investors agreed to purchase, a number of Shares equal to 19.99% of the number of Shares issued and outstanding immediately prior to the Subscription Date (the "Initial Shares") and Warrants to purchase up to a number of Shares equal to 200% of the Initial Shares at an initial closing (the "Initial Closing"), which is expected to occur in the near future. In connection with the Initial Closing, (a) 325 Master Fund will acquire 684,539 Shares and 1,369,078 Warrants, and (b) the SMAs will acquire an aggregate of 2,800,907 Shares and 5,601,814 Warrants. The remaining 13,629,466 Shares and 27,258,932 Warrants will be issued to 325 Master Fund and the SMAs upon the Issuer's receipt of stockholder approval of the 2025 Private Placement (the "Stockholder Approval"). The Warrants are not exercisable unless and until the Issuer obtains the Stockholder Approval. The Warrants are not subject to any redemption provision, and once exercisable, can be exercised for cash or on a cashless basis at the discretion of the holder. The Warrants do not have any voting rights, but do have the right to participate in any dividends or distributions made by the Issuer. The number of Shares underlying, and the exercise price of, the Warrants is subject to full ratchet antidilution protection and standard adjustments in the event of certain events, such as stock splits, combinations, dividends, distributions, reclassifications, mergers or other corporate changes; provided, however, that in no event will the exercise price of the Warrants be equal to less than $0.14944 per Share. The 2025 Purchase Agreement and the Warrants provide that each Investor's beneficial ownership of Shares, including after taking into account the full exercise of such Investor's Warrant, shall in no event exceed 49.5% of the issued and outstanding Shares (the "Maximum Ownership Limitation"). Pursuant to the Warrants, in the event that an Investor's Warrant is not exercisable for Shares due to the beneficial ownership of such Investor exceeding the Maximum Ownership Limitation, the applicable Warrant will be exercisable for shares of the Issuer's Series A Convertible Preferred Stock, par value $0.0001 per share (the "Preferred Stock"), that are convertible into an equivalent number of Shares for which the Warrant is exercisable. The Warrants expire five years from the anniversary of the Initial Closing. The Preferred Stock is pari passu with the Shares, having the same dividend and liquidation rights (on an as-converted basis) as the Shares. The shares of the Preferred Stock are convertible on a one-for-1,000 basis (adjustable for certain recapitalizations and similar events) into Shares (i) at the holder's request as long as the conversion does not cause such holder's beneficial ownership of Shares to exceed the Maximum Ownership Limitation and (ii) automatically upon transfer if such transfer does not cause the transferee's beneficial ownership of Shares to exceed the Maximum Ownership Limitation. Except as otherwise required by law, the Preferred Stock will have no voting rights. The 2025 Purchase Agreement contains a "most favored nation" provision that allows each Investor to claim any preferable terms from any future securities offering by the Issuer and also provides the Investors with certain participation rights in future financings. In addition, pursuant to the 2025 Purchase Agreement, the Issuer agreed not to increase the size of the Issuers board of directors to more than seven directors without the prior written consent of 325. The 2025 Purchase Agreement contains customary representations, warranties and covenants, customary conditions to closing, indemnification obligations of the Issuer, other obligations of the parties, and termination provisions. Among other covenants, the 2025 Purchase Agreement requires the Issuer to file a proxy statement on Schedule 14A with the Securities and Exchange Commission (the "SEC") within fifteen (15) days of the Initial Closing and hold a special meeting of stockholders at the earliest practical date thereafter for purposes of obtaining the Stockholder Approval. In the event that the Issuer fails to obtain the Stockholder Approval by February 28, 2026, the Investors will be refunded all amounts paid into escrow for the remaining Shares and Warrants. In connection with the Initial Closing, certain of the Reporting Persons will be entering into a registration rights agreement with the Issuer, to be effective upon the Initial Closing (the "2025 Registration Rights Agreement") pursuant to which the Issuer is required to file a registration statement with the SEC to register the resale of the Shares and the Shares and Preferred Stock issuable upon exercise of the Warrants be issued in connection with the 2025 Private Placement. In connection with the Initial Closing, certain of the Reporting Persons will be entering into a voting agreement with the Issuer, to be effective upon the Initial Closing (the "2025 Voting Agreement"), to support the transactions contemplated by the 2025 Purchase Agreement, including obtaining the Stockholder Approval. The foregoing descriptions of the 2025 Purchase Agreement, Warrants and Preferred Stock do not purport to be complete and are subject to and are qualified in their entirety by reference to the full text of the Form of 2025 Purchase Agreement, Form of Warrant and Certificate of Designation of the Preferred Stock, copies of which are attached hereto as Exhibits 99.1 and are incorporated by reference herein.
