The information appearing under the section entitled “Selling Securityholders”
in the prospectus is amended and restated by the information appearing below.

SELLING SECURITYHOLDERS

The notes were originally issued in a private offering to Initial Purchasers led by Citigroup Global Markets Inc. and Barclays Bank PLC. The Initial Purchasers have advised us that the notes were resold in transactions exempt from the registration requirements of the Securities Act to “qualified institutional buyers,” as defined by Rule 144A under the Securities Act and outside the United States in reliance on Regulation S. Selling securityholders, including their transferees, pledgees, donees or successors, may from time to time offer and sell pursuant to this prospectus supplement and the underlying prospectus any or all of the notes and the ordinary shares into which the notes are convertible.

The table below sets forth information with respect to the selling securityholders, the principal amount of the notes and the number of ordinary shares into which the notes are convertible beneficially owned by each selling securityholder that may be offered pursuant to this prospectus supplement and the underlying prospectus. Unless set forth below, none of the selling security-holders has had within the past three years any material relationship with us or any of our predecessors or affiliates.

We have prepared the table based on information given to us by, or on behalf of, the selling securityholders on or before October 20, 2004. Because the selling securityholders may offer, pursuant to this prospectus supplement and the underlying prospectus, all or some portion of the notes or ordinary shares listed below, no estimate can be given as to the amount of notes or ordinary shares that will be held by the selling securityholders upon consummation of any sales. In addition, the selling securityholders listed in the table may have sold, transferred or otherwise disposed of, in transactions exempt from the registration requirements of the Securities Act, some or all of their notes since the date as of which the information in the table is presented.

Information about the selling securityholders may change over time. Any changed information given to us by the selling securityholders will be set forth in additional prospectus supplements or amendments to the underlying prospectus if and when necessary.
