Re: Registration Statement/Form S-1A

 

Gentlemen:

 

We have acted as special Nevada counsel to Arch Therapeutics, Inc. (the “Company”) in connection with the filing by the Company of a Registration Statement on Form S-1 (as amended, the “Registration Statement”), as amended, with the Securities and Exchange Commission in connection with the registration under the Securities Act of 1933, as amended (“Securities Act”), of the offering from time to time by the selling stockholders, as described in the Registration Statement, of up to 45,600,000 shares of the Company’s common stock, par value $0.001 per share (the “Common Shares”), including 11,400,000 shares of common stock (“Shares”) currently issued and outstanding and an aggregate of 34,200,000 shares of common stock currently issuable upon the exercise of the Company’s Series A Warrants, Series B Warrants and Series C Warrants (collectively, the “Warrants” and such shares of common stock currently issuable upon exercise of the Warrants, the “Warrant Shares”), all issued and sold in the Company’s private placement offering closed on February 4, 2014, as more fully described in the Registration Statement and associated prospectus. Pursuant to Rule 416 under the Securities Act, the registration includes such indeterminate number of additional shares of common stock of the Company as may be issued or issuable because of stock splits, stock dividends, stock distributions, and similar transactions.

 

As the special Nevada counsel to the Company in connection with the Registration Statement, we have examined the actions taken by the Company in connection with the authorization of the issuance of the Shares, and such documents as we have deemed necessary to render this opinion.

 

Based upon and subject to the foregoing, it is our opinion that (i) the Shares are duly authorized, validly issued, fully paid, and non-assessable; and (ii) the Warrant Shares have been duly authorized and, when issued and paid for upon exercise of the Warrants as contemplated by the Warrants, will be validly issued, fully paid and nonassessable.

 

We consent to the use of this opinion as an exhibit to the Registration Statement and further consent to all references to us in the Registration Statement and any amendment thereto.

  

  Sincerely,
