Shaping the Future: Creating a Global Industry Leader

Forward-Looking Statements These materials include "forward-looking statements" (as defined in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934) including statements regarding, among other things, the benefits of the combination with Inco and the combined company's plans, objectives, expectations and intentions. All statements other than historical information are forward-looking statements. These forward-looking statements are based on management's current beliefs and expectations, speak only as of the date made, and are subject to a number of significant risks and uncertainties that cannot be predicted or quantified and are beyond our control. Future developments and actual results could differ materially from those set forth in, contemplated by or underlying the forward-looking statements. The following factors, among others, could cause actual results to differ from those described in the forward- looking statements in this document: (i) the ability to obtain governmental approvals of the combination on the proposed terms and schedule; (ii) the failure of Inco's shareholders to approve the plan of arrangement; (iii) the failure of Phelps Dodge's shareholders to authorize the issuance of Phelps Dodge common shares, the change of Phelps Dodge's name to (Phelps Dodge Inco) and an increase in the size of Phelps Dodge's board of directors as required under the combination agreement; (iv) the risks that the businesses of Phelps Dodge and Inco and/or Falconbridge will not be integrated successfully; (v) the risks that the cost savings, growth prospects and any other synergies from the combination may not be fully realized or may take longer to realize than expected; (vi) the risks that the cost savings, growth prospects and any other synergies from the combination may not be fully realized or may take longer to realize than expected; (vi) the combined company's inability to refinance indebtedness incurred in connection with the combination on favorable terms or at all; (vii) the possibility that Phelps Dodge will combine with Inco only; (viii) the possible impairment of goodwill resulting from the combination and the resulting impact on the combined company's assets and earnings; and (ix) additional factors that may affect future results of the combined company set forth in Phelps Dodge's, Inco's and Falconbridge's filings with the Securities and Exchange Commission, which filings are available at the SEC's Web site at (www.sec.gov). Except as required by law, we are under no obligation, and expressly disclaim any obligation, to update, alter or otherwise revise any forward-looking statement whether written or oral, that may be made from time to time, whether as a result of new information, future events or otherwise.

Supplemental Data These materials also include terms used to describe supplemental data. Any such data or terms are not a substitute for any U.S. generally accepted accounting principle measure and should be evaluated within the context of our U.S. GAAP results. Any such references may not be comparable to similarly titled measures reported by other companies. As required by Regulation G, we have posted on our Web site - www.phelpsdodge.com - a full reconciliation of non-GAAP financial measures to U.S. GAAP financial measures. Unless otherwise indicated, all information in this presentation relating to Phelps Dodge is on a post-FIN-46 basis (i.e., Candelaria and El Abra are fully consolidated with minority interests shown separately rather than a pro rata consolidation). Note: In connection with the proposed combination, Phelps Dodge intends to file a preliminary proxy statement on Schedule 14A with the SEC. Investors are urged to read the proxy statement (including all amendments and supplements to it) when it is filed because it contains important information. Investors may obtain free copies of the proxy statement, as well as other filings containing information about Phelps Dodge, Inco and Falconbridge, without charge, at the SEC's Web site (www.sec.gov). Copies of Phelps Dodge's filings may also be obtained without charge from Phelps Dodge at Phelps Dodge's Web site (www.phelpsdodge.com) or by directing a request to Phelps Dodge, One North Central Avenue, Phoenix, Arizona 85004-4414, Attention: Assistant General Counsel and Corporate Secretary, (602) 366-8100.
