Serono  announced  that  shareholders  have  approved all the resolutions at the

growth  of  Rebif in the US and the strong overall performance of our business,"
said  Ernesto  Bertarelli,  Chief  Executive  Officer of Serono.  "We also broke
through  the $1.5 billion revenue mark and made a number of significant business
agreements  which  will  support  our  future  growth."

Shareholders approved the following main resolutions:

     -    A  cash  dividend  of  CHF 110.8 million or $81.4 million (1)(2001 CHF
          100.5  million  or  $62.0  million)

     -    Dividend  gross  per  bearer share CHF 7.00 or $5.15 (2001 CHF 6.25 or
