ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On August 13, 2004, the Company and its wholly-owned subsidiary,  Axiom
Pharmaceutical  Corporation,  a  Delaware  corporation,  completed  the  sale of
substantially  all of the assets located at the Company's  former  manufacturing
sites in  Congers,  New York to IVAX  Pharmaceuticals  New York LLC,  a New York
limited  liability  company  ("IVAX").  In exchange for the Congers assets,  the
Company  received  from IVAX cash in the amount of $2.5 million and IVAX assumed
certain  related  liabilities.  The sale  price was  determined  by  arms-length
negotiation between the parties based on a variety of factors.

         The sale of  substantially  all of the Congers assets is described more
fully in the Company's  definitive  proxy  statement on Schedule 14A, filed with
