Upon closing of the transactions contemplated by the August 2025 Exchange Agreement, the August 2025 Exchange Notes and August 2025 Exchange Warrants were cancelled and the Investors relinquished all rights, title and interest in such securities. The August 2025 Exchange Agreement includes certain covenants, including, among others, that (i) the Company will use commercially reasonable efforts to maintain the listing of its common stock on a stock exchange, (ii) while Preferred Stock remains outstanding, (A) during a certain 90 day period, the Company will not, with certain exceptions, offer or issue any equity or related securities, and (B) the Company will not, without approval from the Investors holding a majority of the outstanding Preferred Stock, issue any equity security having a preference over or party with the Preferred Stock with respect to dividends, liquidation or redemption or having a preference over the common stock with respect to dividends, liquidation or redemption, and the Company and its subsidiaries will not incur any indebtedness. The Company also agreed not to enter into any fundamental transaction, such as a merger, sale of more than 50% of the outstanding voting shares, sale of substantially all assets, or business combination, unless such transaction complies with the terms of the Series F Preferred Stock Certificate of Designations and the Series G Certificate of Designations, as amended. The August 2025 Exchange Agreement contains customary representations and warranties between the Company and the Investors.

The issuance of shares of Series F Preferred Stock and Series G Preferred Stock pursuant to the August 2025 Exchange Agreement, and the common stock issuable upon conversion thereof, was made in reliance on the exemption from registration provided by Section 3(a)( 9) of the Securities Act because it involves an exchange with the Company’s exchange security holders exclusively where no commission or other remuneration is paid or given directly or indirectly for soliciting such exchange and Rule 506(b) Regulation D (“Regulation D”) as promulgated by the SEC, because, among other things, the transaction did not involve a public offering and the investors represented that they are accredited investors. *Amendment to Series F Preferred Stock and Series G Preferred Stock Certificates of Designations* On August 14, 2025, the Company filed Certificates of Amendment with the Delaware Secretary of State (each a “Certificate of Amendment” and together, the “Certificates of Amendment”) to each of the Series F Preferred Stock Certificate of Designations (the “Series F Certificate of Designations”) and the Series G Preferred Stock Certificate of Designations (the “Series G Certificate of Designations” and together with the Series F Certificate of Designations, the “Certificates of Designations”), which were originally filed with the Delaware Secretary of State on July 29, 2025.

On August 14, 2025, the Company entered into an Amendment and Exchange Agreement (the “ August 2025 Exchange Agreement”) with certain investors (each individually an “Investor” and collectively, the “Investors”), pursuant to which the Company agreed to exchange (i) certain outstanding senior secured convertible notes with an aggregate principal and accrued interest of approximately $5 million (the “ August 2025 Exchange Notes”) for the issuance of approximately 4,730 shares of Series F Preferred Stock, par value $0.001 per share (“Series F Preferred Stock”) and (ii) warrants issued during August 2025 (the “ August 2025 Exchange Warrants”) for the issuance of approximately 6,362 shares of Series G Preferred Stock, par value $0.001 per share (“Series G Preferred Stock,” and together with the Series F Preferred Stock, the “Preferred Stock”), previously issued pursuant to the Securities Purchase Agreements, as may have been amended from time to time, dated May 14, 2024, January 23, 2025 and March 6, 2025.

The Company also agreed not to enter into any fundamental transaction, such as a merger, sale of more than 50% of the outstanding voting shares, sale of substantially all assets, or business combination, unless such transaction complies with the terms of the Series F Preferred Stock Certificate of Designations and the Series G Certificate of Designations, as amended.

The issuance of shares of Series F Preferred Stock and Series G Preferred Stock pursuant to the August 2025 Exchange Agreement, and the common stock issuable upon conversion thereof, was made in reliance on the exemption from registration provided by Section 3(a)( 9) of the Securities Act because it involves an exchange with the Company’s exchange security holders exclusively where no commission or other remuneration is paid or given directly or indirectly for soliciting such exchange and Rule 506(b) Regulation D (“Regulation D”) as promulgated by the SEC, because, among other things, the transaction did not involve a public offering and the investors represented that they are accredited investors.
