The Registration Statement relates to the proposed issuance and sale by the Company, from time to time, pursuant to Rule 415 under the Securities Act, of up to $50,000,000 of: (i) shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”); (ii) shares of the Company’s preferred stock, par value $0.001 per share (the “Preferred Stock”); and (iii) warrants to purchase Common Stock or Preferred Stock (the “Warrants”. The Common Stock, the Preferred Stock, and the Warrants are referred to herein as the “Securities”.

We have examined copies of such agreements, instruments and documents and undertaken such further inquiry as we consider necessary or advisable for purposes of rendering the opinions set forth below.

In giving this consent, we do not thereby admit that we are an “expert” within the meaning of the Securities Act.
