Ladies and Gentlemen:

We refer to the Registration Statement on Form S-3 (the “Registration Statement”) filed on October 28, 2020 by Workhorse Group, Inc., a Nevada corporation (the “Company”), with the Securities and Exchange Commission with respect to the registration of up to an aggregate of 6,820,512 shares of the Company’s common stock, par value $0.001 per share (the “Shares”) pursuant to (1) a Registration Rights Agreement dated as of December 31, 2018 (“Registration Rights Agreement”), entered into pursuant to that certain Credit Agreement dated December 31, 2018 among the Company, Wilmington Trust, as Agent, and the Lenders party thereto; and (2) a Purchase Agreement between the Company and Antara Capital LP, dated as of October 14, 2020 (the “Purchase Agreement”).

As counsel to the Company, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this 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. We are opining herein as to the Nevada Revised Statutes, and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or, in the case of Nevada, any other laws, or as to any matters of municipal law or the laws of any local agencies within any state.

We have made such examination as we have deemed necessary for the purpose of this opinion.  Based upon such examination, it is our opinion, that Shares have been duly authorized for issuance and, when issued, delivered and paid for in accordance with and in the manner described in the Registration Statement, the Registration Rights Agreement and the Purchase Agreement, the Shares will be validly issued, fully paid and non-assessable.

No opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement, the Registration Rights Agreement or the Purchase Agreement. In connection with this opinion we have examined and relied on the representations and warranties as to factual matters in the Registration Statement. Our knowledge of the Company and its legal and other affairs is limited by the scope of our engagement, which scope includes the delivery of this opinion letter. We do not represent the Company with respect to all legal matters or issues. The Company may employ other independent counsel and, to our knowledge, handles certain matters and issues without the assistance of independent counsel.
