Impact may also file other relevant documents regarding the Business Combination with the SEC. Impact’s stockholders and other interested persons are advised to read, once available, the preliminary Proxy Statement/Prospectus and any amendments thereto and, once available, the definitive Proxy Statement/Prospectus, in connection with Impact’s solicitation of proxies for its special meeting of stockholders to be held to approve, among other things, the proposed merger, because these documents will contain important information about Impact, Zoar Labs Limited, Zoar Limited and the proposed merger. Stockholders of Impact may also obtain a copy of the preliminary or definitive proxy statement, once available, as well as other documents filed with the SEC regarding the proposed merger and other documents filed with the SEC, without charge, at the SEC’s website located at www.sec.gov or by directing a request to: Impact’s Chief Executive Officer at 1400 Broadfield Blvd., Suite 130, Houston, TX.

Participants in the Solicitation

Impact, Zoar Limited, Zoar Labs, and their respective directors and executive officers may be deemed to be participants in the solicitation of proxies from Impact stockholders in connection with the proposed merger. Information about Impact’s directors and executive officers is set forth in Impact’s filings with the SEC. Additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests, by security holdings or otherwise, is contained in the Registration Statement and the Proxy statement/Prospectus included therein.
