The Registration Statement relates to the registration of the offer and resale by certain selling stockholders of the Company of up to 6,497,800 shares of the Company’s Common Stock (the “Common Stock”), par value $0.0001 per share (the “Shares”), which consists of (a) up to an aggregate of 6,130,000 shares of Common Stock that are issuable upon exercise of unregistered warrants (the “PIPE Warrants”) purchased pursuant to the Securities Purchase Agreement, dated June 19, 2024, by and between the Company and the investor signatory thereto (the “Purchase Agreement”), and (b) up to 367,800 shares of Common Stock that are issuable upon the exercise of certain unregistered private placement warrants (the “Placement Agent Warrants” and, together with the PIPE Warrants, the “Warrants”) issued to designees of H.C. Wainwright & Co., LLC, the Company’s placement agent pursuant to an engagement letter, dated as of June 18, 2024.
This opinion letter is being furnished in accordance with the requirements of Item 16 of Form S-1 and Item 601(b)(5)(i) of Regulation S-K promulgated under the Securities Act.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this opinion letter. With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters. In our examination of the aforesaid documents, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the accuracy and completeness of all documents submitted to us, the authenticity of all original documents, and the conformity to authentic original documents of all documents submitted to us as copies (including pdfs). We are opining herein as to the General Corporation Law of the State of Delaware, and we express no opinion with respect to any other laws.
For all purposes of the opinions expressed herein, we have assumed, without independent investigation, the following:
(a) Factual Matters. To the extent that we have reviewed and relied upon (i) certificates of the Company or authorized representatives thereof, (ii) representations of the Company set forth in the Purchase Agreement and (iii) certificates and assurances from public officials, all of such certificates, representations and assurances are accurate with regard to factual matters and all official records (including filings with public authorities) are properly indexed and filed and are accurate and complete.
