We have acted as special securities counsel for JanOne Inc., a Nevada corporation (the “Company”), in connection with the issuance of up to 571,428 shares (the “Shares”) of common stock of the Company, par value $0.001 per share (the “Common Stock”). The Shares are included in a Registration Statement on Form S-3 (File No. 333-251645) (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), and declared effective by the Commission on December 29, 2020, a base prospectus, dated December 23, 2020, included in the Registration Statement at the time it was originally declared effective (the “Base Prospectus”), and a prospectus supplement, dated January 29, 2021, filed with the Commission pursuant to Rule 424(b)(5) under the Securities Act (the “Prospectus Supplement”; together with the Base Prospectus, the “Prospectus”). The Shares are being sold pursuant to a Securities Purchase Agreement, dated January 29, 2021, between the Company and certain purchasers party thereto (the “Securities Purchase Agreement”). The form of Securities Purchase Agreement was filed as an exhibit to a Current Report on Form 8-K and incorporated by reference into the Registration Statement. This opinion is being rendered in connection with the filing of the Prospectus with the Commission. All capitalized terms used herein and not otherwise defined shall have the respective meanings given to them in the Registration Statement and the Prospectus.

You have requested our opinion as to the matters set forth below in connection with the Registration Statement and the Prospectus. In connection with the opinion expressed herein, we have examined such documents, records, and matters of law as we have deemed relevant or necessary for purposes of such opinion including, without limitation: (i) the Registration Statement, the Base Prospectus, and the Prospectus Supplement; (ii) the Articles of Incorporation and Bylaws of the Company, each as amended to date; (iii) the resolutions adopted by the Board of Directors of the Company or authorized committees thereof (either at meetings or by unanimous written consent) authorizing the issuance and sale of the Shares pursuant to the terms of the Registration Statement, including to establish the sale price of the Shares; (iv) the Securities Purchase Agreement; and (v) such other documents and records and matters of law as we have deemed necessary or appropriate for purposes of this opinion.

To the extent relevant to any opinion below, we have also assumed that, at the time of the sale or delivery of the Shares: (i) the Registration Statement is effective under the Securities Act and the rules and regulations promulgated thereunder, and such effectiveness has not been terminated or rescinded, and complied with all applicable laws; (ii) the Prospectus Supplement relating to the Shares being offered was prepared and filed in compliance with the Securities Act and the rules and regulations promulgated thereunder, and complied with all applicable laws; (iii) inasmuch as the Shares being offered are to be sold pursuant to the Underwriting Agreement, such Underwriting Agreement, in the form filed as an exhibit to the Registration Statement, was duly authorized, executed, and delivered by the Company and the other parties thereto, and constitutes a valid, binding, and enforceable obligation of the Company and the other parties thereto, enforceable against each of them in accordance with its terms, and the Shares offered and sold pursuant thereto were offered and sold in accordance with the terms thereof; (iv) the Shares being offered will be issued and sold in compliance with applicable federal and state securities laws and for the consideration set forth in, and otherwise as contemplated by and in conformity with, the Registration Statement, the Prospectus, and the Prospectus Supplement relating to the Shares being offered; (v) any applicable listing or other requirements of the Nasdaq Stock Market have been complied with; (vi) with respect to the Shares issued and sold, there will be sufficient shares of Common Stock authorized and available for issuance, and that the consideration for the issuance and sale of the Shares is in an amount that is not less that the par value of the Common Stock; and (vii) the Company is a corporation duly organized, validly existing, and in good standing under the laws of the State of Nevada and shall have the necessary power and authority to issue and sell the Shares.

On the basis of, and in reliance on, the foregoing examination and subject to the assumptions, exceptions, qualifications, and limitations contained herein, if the Board of Directors of the Company has taken all necessary corporate action to authorize the issuance and sale of the Shares, including the terms of the offering thereof and related matters in accordance with the Securities Purchase Agreement and the applicable purchase or similar agreement therefor, and when issued and paid for as described in the Prospectus, we are of the opinion that the Shares will be duly authorized, validly issued, fully paid, and non-assessable.
