The Prospectus Supplement relates to the issuance and sale by the Company of up to 1,393,939 shares (the “Shares”) of common stock, $0.001 par value (the “Common Stock”), including the Shares issuable upon the exercise of an over-allotment option granted by the Company to the underwriters pursuant to an Underwriting Agreement dated July 1, 2020, between the Company and Maxim Group LLC, as representative of the several underwriters identified therein (the “Underwriting Agreement”). The Underwriting Agreement is being 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 Supplement with the Commission.

In addition, in rendering this opinion, we assumed that the Shares will be offered in the manner and on the terms identified or referred to in the Underwriting Agreement, the Registration Statement and the Prospectus Supplement.

We are admitted to practice law in the State of California, and we render this opinion only with respect to, and express no opinion herein with concerning the application or effect of the laws of any jurisdiction other than, the existing laws of the United States of America, of the State of California and of the State of Nevada, including all applicable provisions of the Constitution of the State of Nevada and reported judicial decisions relating thereto.

Based upon and subject to the foregoing, we are of the opinion that the Shares have been duly authorized for issuance and, when issued, delivered and paid for in accordance with the Underwriting Agreement, the Registration Statement and the Prospectus Supplement, the Shares will be validly issued, fully paid and nonassessable.
