5. The Agreement and certain other Reviewed Documents purport to be governed by the laws of states other than the State of California. We are not licensed to practice law in any state other than the State of California. To the extent that the laws of any jurisdiction other than the internal laws of the State of California, the Federal laws of the United States or the Delaware General Corporation Law (“DGCL”) may bear upon or otherwise be relevant to any of our opinions or other statements expressed in this letter, we have assumed (without rendering any opinion to such effect) that such other laws are in all respects identical to the laws of the State of California, without regard to conflict of law provisions, and would not cause any of our opinions or other statements to be incorrect or misleading or cause us otherwise to change or reword such opinions or other statements.

C. Knowledge:

Whenever an opinion or other statement set forth in this letter is qualified by “known to us,” “to our knowledge” or a similar phrase, it means: (1) the actual knowledge (as opposed to constructive or imputed knowledge) of those lawyers who are currently employed by our law firm and who have rendered legal services to the Company since January 1, 2020; (2) other than an inquiry of the lawyers referred to in clause (1) and our review of the Reviewed Documents, we have not conducted any independent investigation or inquiry to determine the accuracy of such opinion or statement; and (3) no inference as to our knowledge of any matters bearing on the accuracy of any such opinion or statement should be drawn from the fact of our representation of the Company.

D. Opinions:

Based upon and subject to the foregoing and the qualifications and limitations set forth below, we are of the opinion that:

1. The Company is a corporation validly existing and in good standing under the laws of Delaware. The Company has all requisite power and authority, and all material governmental licenses, authorizations, consents and approvals that are required to own and operate its properties and assets and to carry on its business as now conducted and as proposed to be conducted (all as described in the Company’s Registration Statement ). .

2. The Company has all requisite power and authority (i) to execute, deliver and perform the Transaction Documents, (ii) to issue, sell and deliver the Shares and (iii) to carry out and perform its obligations under, and to consummate the transactions contemplated by, the Transaction Documents.

3. All action on the part of the Company, its directors and its stockholders necessary for the authorization, execution and delivery by the Company of the Transaction Documents, the authorization, issuance, sale and delivery of the Shares pursuant to the Agreement and the consummation by the Company of the transactions contemplated by the Transaction Documents has been duly taken. The Transaction Documents have been duly and validly executed and delivered by the Company and constitute the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with their terms, except that (a) such enforceability may be limited by bankruptcy, insolvency or other similar laws affecting the enforcement of creditors’ rights in general and (b) the remedies of specific performance and injunctive and other forms of injunctive relief may be subject to equitable defenses.

4. The Shares which are being issued on the date hereof pursuant to the Agreement have been duly authorized and validly issued and are fully paid and nonassessable and free of preemptive or similar rights, and have been issued in compliance with applicable securities laws, rules and regulations.

5. The Registration Statement which registers the sale of the Shares to the Purchasers is currently effective, and no stop order suspending the effectiveness of the Registration Statement under the Securities Act has been issued and, to our knowledge, no proceedings for that purpose have been instituted or overtly threatened. Any required filing of the Prospectus Supplement pursuant to Rule 424(b) under the Securities Act has been made in the manner and within the time required by Rule 424(b). Each of the Registration Statement, as of the time it became effective and the Prospectus Supplement as of its date and the date hereof, complied as to form in all material respects with the requirements of the Securities Act.

6. To our knowledge, the Company has filed all reports required to be filed by it under Sections 13(a) and 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) since January 1, 2021 (the “SEC Reports”). As of their respective filing dates, the SEC Reports complied in all material respects as to form with the requirements of the Exchange Act and the rules and regulations of the Commission promulgated thereunder.

7. The execution, delivery and performance by the Company of, and the compliance by the Company with the terms of, the Transaction Documents and the issuance, sale and delivery of the Shares pursuant to the Transaction Documents do not (a) conflict with or result in a violation of any provision of law, rule or regulation or any rule or regulation of any Trading Market applicable to the Company or of the Certificate of Incorporation or Bylaws of the Company, (b) conflict with, result in a breach of or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or result in or permit the termination or modification of, any material agreement, instrument, order, writ, judgment or decree known to us to which the Company is a party or is subject that is included in the SEC Reports, (c) result in the creation or imposition of any lien, claim or encumbrance on any of the assets or properties of the Company or (d) result in a violation of any statute, law, rule, or regulation which, in our experience is typically applicable to transactions of the nature contemplated by the Transaction Documents and is applicable to the Company.

8. In connection with the valid execution, delivery and performance by the Company of the Transaction Documents, or the offer, sale, issuance or delivery of the Shares, or the consummation of the transactions contemplated thereby, no consent, license, permit, waiver, approval or authorization of, or designation, declaration, registration or filing with, any court, governmental or regulatory authority, or self-regulatory organization, is required, except for (i) the registration of the offer and sale of the Shares under the Securities Act, which has been effected, (ii) the filing of a Notice of Listing of Additional Shares with The Nasdaq Capital Market and (iii) such consents, approvals, authorizations, orders and registrations or filings as may be required under applicable state securities laws, as to which we express no opinion.

9. The Company is not, and after the consummation of the transactions contemplated by the Transaction Documents shall not be, an Investment Company within the meaning of the Investment Company Act of 1940, as amended.

10. To our knowledge, except as described in the Registration Statement and the Prospectus, or as set forth below, there are no legal, governmental or regulatory investigations, actions suits or proceedings pending to which the Company is or may be a party or to which any property of the Company is or may be the subject which, individually or in the aggregate, if determined adversely to the Company, could reasonably be expected to have a Material Adverse Effect; and to our knowledge, no such investigations, actions, suits or proceedings are threatened or contemplated by any governmental or regulatory authority or threatened by others.

E. Negative Assurance Statement:

The establishment or confirmation of factual matters or of statistical, financial or quantitative information is beyond the scope and purpose of our professional engagement in this matter. Therefore, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Preliminary Prospectus or the Prospectus, and we have not made, or undertaken any obligation to make, any independent check or verification thereof of the accuracy, completeness or fairness of such statements. However, we have participated in telephonic conferences with officers and other representatives of the Company, representatives of the placement agents, counsel for the placement agents and the independent registered public accounting firm for the Company during which telephonic conferences the contents of the Registration Statement, the Preliminary Prospectus and the Prospectus and related matters were discussed.
