Amendment No. 1 to Registration Statement on Form S-4 Material U.S. Federal Income Tax Consequences of the Merger, page 113 1. We note your response to prior comment 14. However, your revised disclosure states that the Merger "should" qualify as a reorganization and furthermore continues to assume the material tax consequences at issue (e.g. "Assuming the Merger constitutes a reorganization...", "If the Merger so qualifies...", etc.). Please revise your prospectus disclosure to provide a firm conclusion regarding treatment of the transaction under Section 368(a) and remove language stating that it is intended that, or generally, certain material tax consequences will apply. Please also remove any statement that assumes the material tax consequences at issue. Refer to Section III of Staff Legal Bulletin No. 19 for guidance. Dane Saglio Seneca Biopharma, Inc.
