Directors of the Company via unanimous written consent on September 13, 2023 and September 18, 2023, relating to the authorization of the Sales Agreement, and the issuance of the Shares, as certified by an officer of the Company as of the date hereof.

We have examined originals or copies of such corporate records and certificates of public officials as we have deemed necessary or advisable for purposes of this opinion. We have relied upon the certificates of all public and corporate officials with respect to the accuracy of all matters contained therein. We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of natural persons and the conformity to originals of all copies of all documents submitted to us.

We note that the Company has reserved, and assume it will continue to maintain reserved, a sufficient number of shares of its duly authorized, but unissued, common stock as is necessary to provide for the issuance of the Shares.

Based on and subject to the foregoing and the qualifications, limitations, exceptions and assumptions set forth below, it is our opinion that the Shares have been duly authorized and, when issued and paid for in accordance with the terms of the Sales Agreement, will be validly issued, fully paid and non-assessable.

We express no opinion as to the laws of any jurisdiction other than the laws of the State of Nevada.

(i) shall not be deemed to be transacting business in any other state or jurisdiction other than the State of Nevada and (ii) does not consent to the jurisdiction of any state other than the State of Nevada.

In giving these consents, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Act, the rules and regulations of the Commission promulgated thereunder, or Item 509 of Regulation S-K. This opinion letter is rendered as of the date first written above and we disclaim any obligation to advise you of facts, circumstances, events or developments which hereafter may be brought to our attention and which may alter, affect or modify the opinion expressed herein. Our opinion is expressly limited to the matters set forth above and we render no opinion, whether by implication or otherwise, as to any other matters relating to the Company or the Shares.
