entirety with the information set forth below with respect to the Selling

offered by the Selling Securityholders hereby. Unless otherwise indicated, none

Supplement or in another supplement to the Prospectus.

(1)  Assumes conversion of all of the holder's LYONs at a conversion rate of
     5.277 ordinary shares per $1,000 principal amount at maturity of the LYONs.
     This conversion rate is subject to adjustment, however, as described under
     "Description of the LYONs--Conversion Rights." As a result, the number of
     our ordinary shares issuable upon conversion of the LYONs may increase or
     decrease in the future. Does not include our ordinary shares that may be
     issued by us upon purchase of the LYONs by us at the option of the holder.

(2)  Calculated based on Rule 13d-3(d)(i) of the Exchange Act, using 134,168,793
     ordinary shares outstanding as of November 9, 2001. In calculating this
     amount for each holder, we treated as outstanding the number of our
     ordinary shares issuable upon conversion of all of that holder's LYONs, but
     we did not assume conversion of any other holder's LYONs. Does not include
     our ordinary shares that may be issued by us upon purchase of the LYONs by
     us at the option of the holder.

(3)  Information about other selling securityholders will be set forth in
     prospectus supplements, if required.

(4)  Assumes that any other holders of LYONs, or any future pledgees, donees,
     assignees, transferees or successors of or from any such other holders of
     LYONs, do not beneficially own any of our ordinary shares other than the
     ordinary shares issuable upon conversion of the LYONs at the initial
     conversion rate.
