             BioMarin and Genzyme Announce FDA Panel Meeting for Aldurazyme

     Novato, Calif. and Cambridge,  Mass. - BioMarin Pharmaceutical Inc. (Nasdaq
and Swiss SWX New  Market:  BMRN)  and  Genzyme  General  (Nasdaq:  GENZ)  today
announced  that the U.S.  Food and Drug  Administration  (FDA) has  advised  the
companies  that  their  biologics   license   application   for   Aldurazyme(TM)
(laronidase)  will be reviewed by the FDA's  Endocrinologic  and Metabolic Drugs
Advisory  Committee on January 15, 2003.  Genzyme also announced  today that the
same panel will review its application to market Fabrazyme(TM) (agalsidase beta)
for the treatment of Fabry disease on January 13.

     Aldurazyme is an investigational  enzyme  replacement  therapy for patients
with  mucopolysaccharidosis  I (MPS I). A  Marketing  Authorization  Application
(MAA) for  Aldurazyme is under review at the European  Agency for the Evaluation
of Medicinal  Products (EMEA);  the companies expect a response from EMEA in the
first half of 2003.

About MPS I

     MPS I is a progressive,  debilitating and fatal genetic disease caused by a
deficiency  of the  enzyme  alpha-L-iduronidase.  This  deficiency  leads to the
accumulation of complex  carbohydrates in the lysosomes of cells, leading to the
progressive  dysfunction  of  cellular,  tissue  and  organ  systems.  Resulting
manifestations,  which span a spectrum of severity, can include impaired cardiac
and  pulmonary  function,  delayed  physical  development,  skeletal  and  joint
deformities,  reduced endurance,  and in some cases,  delayed mental function. A
majority of patients die before adulthood from complications of the disease.

     BioMarin  and  Genzyme  formed  a joint  venture  in 1998  to  develop  and
commercialize  Aldurazyme  worldwide.  Under the terms of the joint venture,  if
approved for commercial sale,  BioMarin will manufacture  Aldurazyme and Genzyme
will have responsibility for the commercialization of the product. The companies
have obtained  Orphan Drug  designation and Fast Track status for Aldurazyme for
the  treatment of MPS I from the FDA and orphan  medicinal  product  designation
from the EMEA.



     Genzyme General  develops and markets  therapeutic  products and diagnostic
products and  services.  Genzyme  General has five  therapeutic  products on the
market and a strong pipeline of therapeutic  products in development  focused on
