  On
        August
        30, 2007, Cytogen Corporation ("Cytogen") and InPharma AS ("InPharma") executed
        an amendment to the Product License and Assignment Agreement dated as of October
        11, 2006 (the "License Agreement") between the parties.  Under
        the License Agreement, InPharma granted Cytogen exclusive rights for
        CAPHOSOL
  ®
  in
        North America.  The License Agreement also provides Cytogen with the
        option to acquire the rights to CAPHOSOL for the European and Asian
        markets.
  Under
        the
        amendment to the License Agreement, Cytogen and InPharma restructured the
        amounts payable by Cytogen in connection with the exercise of the option for
        European marketing rights.  Cytogen currently is seeking a strategic
        partner to market CAPHOSOL in Europe.
  CAPHOSOL
        is an advanced electrolyte solution for the treatment of oral mucositis caused
        by radiation or high dose chemotherapy and dry mouth that is approved in the
        U.S. as a prescription medical device.  Cytogen introduced CAPHOSOL to
        the U.S market in March 2007.
