(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 on February 14, 2002, affiliates of Deutsche Banc AG 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 10.41% of our outstanding common stock as of September 6, 2002. Additionally, affiliates of Deutsche Banc AG 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 September 11, 2002.
