         This prospectus  supplement  supplements the prospectus dated September

similar information in the prospectus:

                                 ---------------



                             SELLING SECURITYHOLDERS

         The  following  table  presents  information  provided  by the  Selling
Securityholders  with respect to beneficial  ownership of our ordinary shares as
of December 31, 2001,  and as adjusted to reflect the sale of the shares offered
by this prospectus and prospectus supplement, by the Selling Securityholders and
assumes that all shares being offered by this  prospectus are ultimately sold in
the offering by the Selling Securityholders.

The table includes all shares  issuable within 60 days of December 31, 2001 upon
the exercise of options,  warrants and other  rights  beneficially  owned by the
indicated  shareholders  on that  date and  registered  under  the  registration
statement  of  which  this  prospectus  and  prospectus  supplement  are a part.
Beneficial  ownership as set forth below includes the power to direct the voting
or the  disposition  of the  securities  or to receive the  economic  benefit of
ownership of the securities. To our knowledge, except under applicable community
property  laws or as otherwise  indicated,  the persons  named in the table have
sole voting and sole investment control with respect to all shares  beneficially
owned.  The applicable  percentage of ownership for each shareholder is based on
17,496,819  ordinary  shares  outstanding as of December 31, 2001 and 16,123,578
ordinary  shares  outstanding  immediately  following  the  completion  of  this
offering,  together with applicable options and/or warrants for that shareholder
