The Resale Shares, the Warrant Shares, the Underlying Common Shares, the Common Warrants and the Series A Preferred Shares are included in a registration statement on Form S-3 under the U.S. Securities Act of 1933, as amended (the “Act”), filed with the United States Securities and Exchange Commission (the “Commission”) on the date hereof (the “Registration Statement”).
