Item 4 — Purpose of Transaction

On September 1, 2026, the Reporting Person, as one of the multiple purchasers, entered into a Securities Purchase Agreement (the "SPA") with David E. Lazar (the "Seller"), the then controlling shareholder of the Issuer, pursuant to which the Reporting Person agreed to purchase, in a private transaction, 193,347 shares of Series AAA Preferred Stock of the Issuer, which were subsequently converted into 26,121,180 shares of Common Stock of the Issuer, from the Seller for an aggregate purchase price of $1,296,000. The transactions contemplated by the SPA occurred on September 25, 2026. In connection with the closing of the transaction contemplated by the SPA, William H Crampton was appointed to serve as a member of the board of directors of the Issuer (the "Board") to fill in the vacancy due to the resignation of the Avraham Ben-Tzv. The foregoing description of the SPA does not purport to be complete and is qualified in its entirety by reference to the full text of the SPA, which is filed as Exhibit 99.1 hereto. Depending on prevailing market, economic and other conditions, the Reporting Person may from time to time acquire additional Common Stock or engage in discussions with the Issuer concerning future acquisitions of its shares. Such acquisitions may be made by means of open-market purchases, privately negotiated transactions, direct acquisitions from the Issuer or otherwise. Except as set forth in this Item 4, the Reporting Person has no plans or proposals that 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 material change in the present capitalization or dividend policy of the Issuer; (e) any other material change in the Issuer's business or corporate structure; (f) changes in the Issuer's charter, by-laws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (g) 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; (h) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended; or (i) any action similar to any of those enumerated above. The Reporting Person may, at any time and from time to time, formulate other purposes, plans or proposals regarding the Issuer, or any other actions that could involve one or more of the types of transactions or have one or more of the results described in clauses (a) through (i) of this Item 4.
