(2) Calculated based on Rule 13d-3(d)(i) of the Exchange Act, using 134,496,713 Ordinary Shares outstanding as of March 18, 2002. 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 Debentures, but we did not assume conversion of any other holder's Debentures. Does not include our Ordinary Shares that may be issued by us upon purchase of the Debentures 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 Debentures, or any future pledgees, donees, assignees, transferees or successors of or from any such other holders of Debentures, do not beneficially own any of our Ordinary Shares other than the Ordinary Shares issuable upon conversion of the Debentures at the initial conversion rate.
