Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as Nevada counsel to Ondas Holdings Inc., a Nevada corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-3 on the date hereof (as amended from time to time, the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”).

The Registration Statement relates to the registration and sale by the selling securityholders named in the Registration Statement of an aggregate of 780,000 shares (the “Shares”) of common stock, par value $0.0001 per share, of the Company (the “Common Stock”) issued to BAR Holdings, Inc. (f/k/a Ardenna, Inc.) ("Ardenna") in connection with the acquisition of the assets of Ardenna that closed on April 5, 2022. 

This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act in connection with the filing of the Registration Statement. All capitalized terms used herein and not otherwise defined shall have the respective meanings given to them in the Registration Statement.

In connection with this opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Registration Statement and exhibits thereto, including the prospectus comprising a part thereof; (ii) the Amended and Restated Articles of Incorporation of the Company, as amended, as currently in effect; (iii) the Amended and Restated Bylaws of the Company, as amended, as currently in effect; and (iv) certain resolutions and minutes of meetings of the Board of Directors of the Company relating to (A) the issuance and sale of the Shares, (B) the specimen Common Stock certificate, and (C) other related matters. For the purpose of rendering this opinion, we have made such factual and legal examinations as we deemed necessary under the circumstances, and in connection therewith we have examined, among other things, originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials, certificates of officers or other representatives of the Company, and other instruments and have made such inquiries as we have deemed appropriate for the purpose of rendering this opinion.

In our examination, we have assumed without independent verification the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified, conformed or photostatic copies, and the authenticity of the originals of such copies. In making our examination of executed documents, we have assumed that the parties thereto, other than the Company, had the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and the execution and delivery by such parties of such documents and the validity and binding effect thereof on such parties. Our opinions are subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity). As to any facts material to the opinions expressed herein which were not independently established or verified, we have relied upon oral or written statements and representations of officers or other representatives of the Company and others.

On the basis of, and in reliance on, the foregoing examination and subject to the assumptions, exceptions, qualifications and limitations contained herein, we are of the opinion that the Shares to be resold by the selling securityholders, have been duly and validly authorized for issuance.
