LoanAmendment

On September 19, 2023, SMX (Security Matters) Public Limited Company (the “Company”) amended its (a) loan agreement dated September 7, 2015 (as amended to date, the “Degania Agreement”), by and between Degania A. Business AGSHAH Ltd. and Kibbutz Degania and Kamea-the United Kibbutz Movement Ltd. (public benefit company) (“Kamea”) and (b) loan agreement dated September 7, 2015 (as amended to date, “Ketura Agreement” and, with the Degania Agreement, the “Loan Agreements”), between Ketura International Energy AGSHAH Ltd. and Kibbutz Ketura.

Pursuant to the amendment to the Loan Agreements (the “Amendment”), among other things, Kamea agreed to convert $657,203 of indebtedness (the “Indebtedness Amount”) under the Loan Agreements into 487,281 ordinary shares of the Company (the “Shares”), as payment in full for such indebtedness; provided however, that in the event the proceeds received from Kamea with respect to any sales of the Shares are not at least equal to the Indebtedness Amount, the Company will remain liable to Kamea for the balance of the Indebtedness Amount. The Company intends to promptly file a registration statement to register the Shares on behalf of Kamea.

The Shares will be issued in a private placement under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), and have not been registered under the Securities Act or applicable state securities laws. Accordingly, the Shares may not be offered or sold in the United States except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act and such applicable state securities laws. This Report on Form 6-K shall not constitute an offer to sell or a solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state or other jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or other jurisdiction.

The foregoing is a brief description of the Amendment, and is qualified in its entirety by reference to the full text of the Amendment.
