Item 5.  Other Events
- -------  ------------

                  Enzon, Inc.  ("Enzon" or the "Company")  announced that it has
selected  Medac GmbH (MEDAC) as its  marketing  partner in Europe and Russia for
ONCASPAR (Registered Trademark).  ONCASPAR is Enzon's oncology product now being
sold in the U.S. for the  indication of acute  lymphoblastic  leukemia (ALL) for
patients  who  are  hypersensitive  to  native  forms  of  asparaginase.  MEDAC,
headquartered   in  Hamburg,   Germany,   develops  and  markets  anti-  cancer,
anti-coagulant and diagnostic products.  MEDAC will buy ONCASPAR from Enzon at a
set price which  increases  over the term of the  agreement.  The agreement also
contains escalating minimum annual purchase  requirements.  Additionally,  MEDAC
will be  responsible  to obtain  registrations  for  ONCASPAR  in the  remaining
European  countries  where it is not yet approved,  market the product in Europe
and  Russia,  and  conduct  clinical  trials  in Europe  for front  line use and
additional  indications  including  non-Hodgkin's  lymphoma,  adult ALL, chronic
lymphocytic  leukemia  (CLL) and AIDS related  lymphoma.  MEDAC has an extensive
sales base in Germany where ONCASPAR is already  approved,  as well as marketing
capabilities throughout the rest of Europe and Russia. In particular,  MEDAC has
extensive  sales   experience  with  the  leukemia  market  in  Europe.   Native
asparaginase  is currently  sold in Europe as a treatment for not only pediatric
ALL, but also for adult ALL, non-Hodgkin's lymphoma and other indications.

         Enzon also announced that it has successfully completed the transfer of
know-how  for  the   manufacture   of  PEG-INTRON  A  to  Schering   Corporation
("Schering"),  a subsidiary of Schering-Plough  Corporation,  and has received a
payment of $1  million.  In 1995,  Schering  and Enzon  amended  their  existing
agreement to include the transfer of Enzon's PEG-INTRON A know-how and worldwide
manufacturing  rights to Schering  for $3 million,  of which $2 million was paid
last year. At that time,  Schering  invested $2 million in Enzon's common stock.
Enzon retained the option to be Schering's exclusive manufacturer of the product
for the U.S. market.
