Ladies and Gentlemen:

We have acted as counsel to Rezolute, Inc., a Nevada corporation (the “Company”), in connection with Registration Statement on Form S-3 (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, relating to the resale of up to 1,295,383 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share, by certain selling stockholders named in the Registration Statement (the “Selling Stockholders”) issued pursuant to the securities purchase agreement by and among the Company and certain Selling Stockholders.

We have examined such documents and have reviewed such questions of law as we have considered necessary or appropriate for the purposes of our opinions set forth below.

We have also assumed the legal capacity for all purposes relevant hereto of all natural persons.
