MEDIA  RELEASE


FOR  IMMEDIATE  RELEASE
-----------------------


                     SERONO AND AMGEN SIGN LICENSE AGREEMENT
                         FOR MULTIPLE SCLEROSIS PRODUCT


THOUSAND  OAKS,  CALIFORNIA,  USA  AND GENEVA, SWITZERLAND - NOVEMBER 13, 2002 -
Amgen  Inc. (NASDAQ:AMGN) and Serono S.A. (virt-x: SEO and NYSE: SRA). Amgen and
Serono  announced  today  that  they have signed a license and commercialization
agreement  by which Serono will sell the marketed drug Novantrone  (mitoxantrone
for  injection concentrate) in the United States.  Novantrone is approved by the
FDA  in  the  United States for secondary progressive, progressive relapsing and
worsening  relapsing-remitting  multiple sclerosis, as well as for certain forms
of  cancer  in  the  United  States.  The  terms  were  undisclosed.

Novantrone  was  acquired  by  Amgen  in  connection with Amgen's acquisition of
Immunex  Corporation  in  July  2002.  The  drug  was approved by the FDA for MS
indications in October, 2000, and had US sales of $71 million last year.  It has
also been approved for certain oncology indications since 1987. Full prescribing
information  for  Novantrone  can  be  obtained  by visiting www.novantrone.com.
                                                             -------------------

Closing of the transaction is subject to review and clearance by U.S. regulatory
authorities.

Amgen  is  a global biotechnology company that discovers, develops, manufactures
and  markets  important  human  therapeutics  based  on advances in cellular and
molecular  biology. Serono is a global biotechnology leader with six recombinant
products  on  the  market,  Gonal-F  ,  Luveris  ,  Ovidrel /Ovitrelle , Rebif ,
Serostim  and  Saizen  (somatropin).  (Luveris  is  not  approved  in  the USA).



This  news  release contains forward-looking statements that involve significant
risks  and uncertainties, including the possibility that the license transaction
will  not  close  or that the companies may be required to modify aspects of the
transaction  to  achieve  regulatory approval, and other risks and uncertainties
including  those  discussed below and more fully described in the Securities and
Exchange Commission reports filed by Amgen, including its most recent Form 10-Q.
Amgen conducts research in the biotechnology/pharmaceutical field where movement
from  concept  to  product is uncertain; consequently, there can be no guarantee
that any particular product candidate will be successful and become a commercial
product.  Furthermore,  our  research,  testing,  pricing,  marketing  and other
operations  are  subject  to  extensive  regulation  by  domestic  and  foreign
government  regulatory  authorities.  In  addition,  sales  of  our products are
affected  by  reimbursement  policies  imposed  by third party payors, including
governments,  private  insurance  plans  and  managed  care  providers.  These
government  regulations  and  reimbursement policies may affect the development,
usage  and  pricing  of  our  products.
In  addition, while we routinely obtain patents for our products and technology,
the protection offered by our patents and patent applications may be challenged,
invalidated  or  circumvented  by  our  competitors.  Because  forward-looking
statements involve risks and uncertainties, actual results may differ materially
from  current  results expected by Amgen. Amgen is providing this information as
of  November  13,  2002  and  expressly disclaims any duty to update information
contained  in  this  press  release.


Some  of  the  statements  in  this  press  release  are  forward  looking. Such
statements  are inherently subject to known and unknown risks, uncertainties and
other  factors  that  may  cause  actual results, performance or achievements of
Serono  S.A.  and  affiliates  to be materially different from those expected or
anticipated  in  the  forward-looking statements. Forward-looking statements are
based on Serono's current expectations and assumptions, which may be affected by
a  number  of  factors, including those discussed in this press release and more
fully  described  in  Serono's  Annual  Report  on Form 20-F filed with the U.S.
Securities  and  Exchange  Commission on May 21 2002.  These factors include any
failure  or  delay  in  Serono's ability to develop new products, any failure to
receive  anticipated  regulatory  approvals,  any  problems  in  commercializing
current  products  as  a  result of competition or other factors, our ability to
obtain  reimbursement  coverage  for  our  products,  and government regulations
limiting  our  ability  to  sell  our  products. Serono has no responsibility to
update the forward-looking statements contained in this press release to reflect
events  or  circumstances  occurring  after  the  date  of  this  press release.
