On December 2, 2024, the Reporting Persons and other unrelated investors entered into a Securities Purchase Agreement with the Issuer (the "Purchase Agreement"), pursuant to which the Reporting Persons purchased (i) 2,222 shares of the Issuer's Series A Preferred Stock (the "Series A") for an aggregate offering price of approximately $5.5 million and (ii) a warrant (the "Warrant") to purchase 3,333,000 shares of Issuer's Common Stock exercisable thereunder (the " Warrant Shares"). The Warrant has an exercise price per share of $2.30. The Warrant is exercisable at any time and from time to time on or after the Stockholder Approval (as defined below) until the five-year anniversary of the Warrant's issue date. BHC may not exercise the Warrant if BHC, together with its affiliates, would beneficially own more than 19.99% of the number of shares of the Common Stock outstanding immediately after giving effect to such exercise. BHC may increase or decrease this percentage not in excess of 45.00% by providing at least 61 days' prior notice to the Issuer. Subject to the terms and limitations contained in the Certificate of Designation of Preferences, Rights and Limitations of Series A Convertible Preferred Stock (the "Certificate of Designation") governing the Series A, the Series A will not become convertible until the Issuer's stockholders approve (i) the issuance of all Common Stock issuable upon conversion of the Series A and (ii) the issuance of the Warrant Shares upon exercise of the Warrant (collectively, the "Stockholder Approval"). On the first trading day following the announcement of the Stockholder Approval, the Issuer may, at its option, cause each share of Series A to automatically convert into such number of shares of Common Stock, at the conversion price of $2.25 per share (the "Conversion Price"), subject to the terms and limitations contained in the Certificate of Designation. Additionally, subject to the terms and limitations in the Certificate of Designation, if the Issuer has not elected to automatically convert the Series A, then at the option of each individual holder of Series A, each share of the Series A held by such holder, not otherwise converted, shall be convertible into the applicable number of shares of Common Stock at the Conversion Price. On March 6, 2025, the Issuer's stockholders approved, among other things, subject to certain conditions, the issuance of the Issuer's outstanding Common Stock in accordance with Nasdaq Listing Rule 5635, upon (i) the conversion of the Series A pursuant to the terms of the Certificate of Designation and (ii) the exercise of Warrants and the underlying Warrant Shares at less than the "minimum price" under Nasdaq Listing Rule 5635(d), and each of (i) and (ii) which may be deemed a "change of control" under Nasdaq Listing Rule 5635(b), including the issuance of equity compensation to one of the Issuer's officers upon conversion of the Series A and the exercise of the Warrants to purchase Warrant Shares at less than market value under Nasdaq Listing Rule 5635(c). On March 10, 2025, following the Stockholder Approval, the Issuer exercised its option to automatically convert each share of Series A into 1,000 shares of Common Stock. Accordingly, BHC owns 2,809,848 shares of the Issuer's Common Stock. Further, BHC also has a right to exercise its Warrant to purchase 3,333,000 Warrant Shares but since the BHC's ownership as of the date of this filing is in excess of the 19.99% beneficial ownership limitation only a portion of the Warrant Shares, 2,980,148, are exercisable as of the date of this filing. The foregoing description is qualified in its entirety by the full text and form of the Certificate of Designation, the Warrant, and the Purchase Agreement, copies of which are filed herewith as Exhibits 7.03, 7.04 and 7.05, respectively. The source of the funds for the purchases by BHC described above was from available cash on hand.

Other than as described above, and except that the Reporting Persons may, from time to time or at any time, subject to market conditions and other factors, purchase additional shares of Common Stock in the open market, in privately negotiated transactions or otherwise, or sell at any time all or a portion of the shares of Common Stock now owned or hereafter acquired by them to one or more purchasers, the Reporting Persons do not have any present plans which relate to or would result in: (a) the acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (e) any material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer's business or corporate structure; (g) changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or j) any action similar to any of those actions enumerated above.

BHC - 19.99% BUSH LLC - 19.99% Guth - 19.99% Ramamurthy - 19.99% Each Reporting Person disclaims beneficial ownership of the shares other than those shares which such person owns of record. The percentage of outstanding Common Stock of the Issuer which may be deemed to be beneficially owned by each Reporting Person is set forth on Line 13 of such Reporting Person's cover sheet. Such percentage was calculated based on (a) 4,829,457 shares of Common Stock reported by the Issuer to be outstanding as of January 21, 2025, on the Issuer's Definitive Proxy Statement filed with the SEC on January 27, 2025 and (b) 21,157,000 shares of Common Stock issued in connection with the automatic conversion of the Series A sold pursuant to the Purchase Agreement.

(ii) shared power to vote or to direct the vote: See line 8 of cover sheets. (iii) sole power to dispose or to direct the disposition: See line 9 of cover sheets.
