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

     /(1)/  We believe that any registered sales under the prospectus and its
            accompanying supplements that exceed the total principal amount of
            notes originally issued by us is the result of sales by selling
            securityholders that acquired previously registered notes and
            subsequently requested that those notes be registered.

                  The number of shares of common stock owned prior to the
offering includes shares of common stock into which the notes are convertible.
The number of shares of common stock offered hereby is based on a conversion
price of $60.60 per share of common stock and a cash payment in lieu of any
fractional share. Information concerning other selling securityholders will be
set forth in prospectus supplements from time to time, if required. The number
of shares of common stock owned by the other selling securityholders or any
future transferee from any such holder assumes that they do not beneficially own
any common stock other than common stock into which the notes are convertible at
a conversion price of $60.60 per share.

                  Except as set forth in this paragraph, none of the selling
securityholders nor any of their affiliates, officers, directors or principal
equity holders has held any position or office or has had any material
relationship with us within the past three years. Based exclusively on a
Schedule 13G filed with the Securities and Exchange Commission, affiliates of
Deutsche Banc Alex Brown Inc. own common stock and Chess Units of Foreign
Securities ("CUFS") that are convertible into common stock which, assuming
conversion of the CUFS, represent in the aggregate approximately 12.1% of our
outstanding common stock as of September 30, 2001. Additionally, affiliates of
Deutsche Banc Alex Brown Inc. provided us with a bridge loan facility used in
connection with our purchase of MAP Medizin-Technologie GmbH in February, 2001.
A portion of the proceeds we received upon the sale of the notes was used to
repay this bridge loan.


                  INVESTING IN THE NOTES OR THE COMMON STOCK INTO WHICH THE
NOTES ARE CONVERTIBLE INVOLVES A HIGH DEGREE OF RISK. PLEASE CONSIDER THE "RISK
FACTORS" BEGINNING ON PAGE 5 OF THE PROSPECTUS.

                  NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE
SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED
UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
CONTRARY IS A CRIMINAL OFFENSE.

          The date of this prospectus supplement is February 15, 2002.
