In connection herewith, we have examined the originals, or photocopies or copies, certified or otherwise identified to our satisfaction, of: (i) the Registration Statement, as amended, filed by the Company with the SEC and to which this opinion is attached as an exhibit; (ii) the articles of association of the Company, as currently in effect (the “Articles”); (iii) a draft of the amended articles of association of the Company, to be in effect immediately prior to the closing of the Merger (the “Amended Articles”); (iv) resolutions of the board of directors of the Company (the “Board”) and the shareholders of the Company (the “Shareholders”) which have heretofore been approved and relate to the Registration Statement and to the consummation of the transactions contemplated by the Business Combination Agreement and other actions to be taken in connection therewith; (v) the Business Combination

Agreement, (vi) the applicable warrant agreements for the Public Warrants, Private Placement Warrants and PIPE Warrants; and (vii) such other corporate records, agreements, documents and other instruments, and such certificates or comparable documents of public officials and of officers of the Company as we have deemed relevant and necessary as a basis for the opinions hereafter set forth. We have also made inquiries of such officers as we have deemed relevant and necessary as a basis for the opinions hereafter set forth.

In such examination, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, confirmed as photostatic copies and the authenticity of the originals of such latter documents. As to all questions of fact material to the opinion set forth below that have not been independently established, we have relied upon certificates or comparable documents of officers and representatives of the Company.

On the basis of the foregoing, and in reliance thereon, we are of the opinion that (i) the Ordinary Shares, the Francisco Shares, the FPA Shares, the Escrow Shares and PIPE Shares that have been previously issued by the Company have been duly authorized, and are validly issued, fully paid and non-assessable; (ii) the Private Placement Warrants and PIPE Warrants, assuming they were executed and delivered in accordance with the provisions of the applicable warrant agreements governing such warrants, have been duly authorized, validly issued, fully paid and non-assessable; and (iii) the Ordinary Shares issuable upon the exercise of the Public Warrants, Private Placement Warrants and PIPE Warrants have been duly authorized, and when issued and delivered against payment therefore pursuant to the applicable warrants and related warrant agreements, will be validly issued, fully paid and non-assessable.

Members of our firm are admitted to the Bar in the State of Israel, and we do not express any opinion as to the laws of any other jurisdiction. This opinion is limited to the matters stated herein and no opinion is implied or may be inferred beyond the matters expressly stated.

We consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm appearing under the caption “Legal Matters” in the prospectus forming part of the Registration Statement. In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act, the rules and regulations of the SEC promulgated thereunder or Item 509 of the SEC’s Regulation S-K promulgated under the Securities Act.
