Ladies and Gentlemen:


We have acted as special Nevada counsel to Arch Therapeutics, Inc. (the “Company”) in connection with the sale and issuance (the “Offering”) of up to 14,285,714 shares of the Company’s common stock, par value $0.001 per share (the “Common Stock” and such shares, the “Shares”), Series I Common Stock Purchase Warrants (the “Series I Warrants”) to purchase up to an aggregate of 14,285,714 shares of Common Stock (the “Series I Warrant Shares”), and the issuance of a warrant (the “Placement Agent Warrant” and together with the Series I Warrants, the “Warrants”) to H.C. Wainwright & Co., LLC, the Company’s exclusive placement agent (the “Placement Agent”), as part of the compensation payable to the Placement Agent in connection with this Offering, to purchase up to an aggregate of 1,071,429 shares of Common Stock (the “Placement Agent Warrant Shares”, and together with the Series I Warrant Shares, the “Warrant Shares”), pursuant to the Registration Statement on Form S-3 (File No. 333-213878) (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations promulgated thereunder, and declared effective by the Commission on October 20, 2016, together with the Prospectus contained therein (the “Prospectus”), and supplemented by the Prospectus Supplement filed on the date hereof (the “Prospectus Supplement”). The Shares and Series I Warrants are to be sold to certain institutional and accredited investors pursuant to a Securities Purchase Agreement dated October 16, 2019 (the “SPA”).


As the special Nevada counsel to the Company in connection with the proposed potential issuance and sale of the above-referenced Shares, Warrants and Warrant Shares, we have examined the actions taken by the Company in connection with the authorization of the issuance of the Shares, the Warrants, and the Warrant Shares, and such documents as we have deemed necessary to render this opinion. We have examined and relied upon certificates of public officials and, as to certain matters of fact that are material to our opinion, we have also relied upon the representations and warranties of the Company contained in a certificate of an officer of the Company.
