Waiver and Amendment Letter

Ladies and Gentlemen:

          We refer to the Loan Agreement dated as of December 22, 2005 among Inco Limited (“you” or the “Borrower”), as borrower, Royal Bank of Canada, as administrative agent, and Morgan Stanley Senior Funding (Nova Scotia) Co. (“MSSF”), Royal Bank of Canada (“RBC”), Goldman Sachs Canada Credit Partners Co. (“GSCCP”), and The Bank of Nova Scotia (“BNS” and, together with MSSF, RBC, BNS and GSCCP, “we” or “us”) and the other banks and other financial institutions party thereto as lenders, as amended by the document entitled First Amendment Agreement between such parties dated as of January 31, 2006 and as further amended by the document entitled Second Amendment Agreement between such parties dated as of February 20, 2006 (such loan agreement as so amended, the “Existing Credit Agreement”). Capitalized terms used but not defined in this letter (the “Waiver and Amendment Letter”) are used with the meanings given to them in the Existing Credit Agreement.

          You have told us that you intend to: (i) enter into the transactions (the “Portugal Transactions”) described in Schedule A hereto; (ii) in connection with such transactions, incur

subordinated convertible debt in the principal amount of up to US$3,000,000,000 from a company (“Portugal”) identified by you to us on the terms and conditions set forth in Schedule B to this Waiver and Amendment Letter (such debt on such terms, the “Portugal Convertible Debt”); and (iii) amend the Support Agreement in the manner described in Schedule C hereto (each such amendment, collectively, the “Support Agreement Amendments”).

Consents in Connection with Portugal Transactions

          Each of the undersigned Lenders (who together constitute the “Majority Lenders” under the Existing Credit Agreement) hereby:

	(i)		consents, pursuant to Section 5.04(e) and Section 9.01, respectively, of the Existing Credit Agreement, to the incurrence of the Portugal Convertible Debt and the proposed use of proceeds thereof notwithstanding Section 5.04(e) or (g) of the Existing Credit Agreement;
	(ii)		consents, pursuant to and to the extent required by Section 5.05 of the Existing Credit Agreement, to the Support Agreement Amendments.

In addition, each of the undersigned Lenders hereby:

	(i)		waives its rights under Section 2.09(a)(y) of the Existing Credit Agreement to be prepaid an amount equal to its pro rata share of the proceeds of the Portugal Convertible Debt or have its Unused Bridge Loan Commitment (as defined in the Existing Credit Agreement) reduced by such amount; and
	(ii)		waives, with respect to the Portugal Convertible Debt, its rights (or those of its affiliates, as the case may be) under the second paragraph under the heading “Compensation” of the Engagement Letter dated October 10, 2005 between Morgan Stanley & Co. Incorporated, RBC Dominion Securities Inc., BNS and Goldman, Sachs & Co.

          Promptly following your acceptance of this Waiver and Amendment Letter, you shall promptly request a like waiver (to the extent applicable) and consent from each of the other Lenders in the manner described in the Existing Credit Agreement; provided, for the avoidance of any doubt, that there shall be no consequences other than such as may be set out in the Existing Credit Agreement for your failure to obtain such waiver and consent from such other Lenders.

Amendments to Existing Credit Agreement

          The definition of “Change of Control” in the Existing Credit Agreement is hereby deleted in its entirety and replaced with the following:

          ““Change of Control” shall be deemed to have occurred at such time as:

(i)

any person or group (as such terms are used in Section 13(d) or Section 14(d) of the 1934 Act), other than Inco or any Subsidiary of Inco or their Affiliates (or their legal representatives) or any employee benefit plan of

			Inco or any Subsidiary of Inco files or is required to file a Schedule 13D or Schedule TO (or any successor schedule form, or report under the 1934 Act) disclosing that such person has become the beneficial owner (as the term “beneficial owner” is used in Rule 13d-3 under the 1934 Act) of more than 50% of the total number of votes attached to all voting securities of Inco then outstanding.
	(ii)		any offeror (as the term “offeror” is defined in Section 89(1) of the OSA for the purpose of Section 101 of the OSA, or any successor provision to either of the foregoing) files or is required to file a report with any securities commission or securities regulatory agency in Canada, disclosing that the offeror has acquired beneficial ownership (within the meaning of the OSA) of, or the power to exercise control or direction over, or securities convertible into, any voting or equity shares of Inco that, together with such offeror’s securities (as the term “offeror’s securities” is defined in Section 89(1) of the OSA or any successor provision thereto in relation to the voting or equity shares of Inco) would constitute voting or equity shares of Inco representing more than 50% of the total number of votes attached to all voting securities of Inco then outstanding;
	(iii)		there is consummated any consolidation, merger, amalgamation, statutory arrangement (involving a business combination), amendment to articles, or similar transaction of Inco (A) in which Inco is not the continuing or surviving corporation, or (B) pursuant to which the common shares of Inco would be redeemed, changed, or converted into or exchanged for cash, securities, or other property;
	(iv)		a majority of the members of the board of directors of Inco cease to be, for at least 90 days, Continuing Directors; or
	(v)		the Effective Date of the Plan of Arrangement (as each such term is defined in the Combination Agreement dated June 25, 2006 between the Borrower and Portugal) occurs,

other than (in each of the cases set out in paragraphs (i), (ii), and (iii) above) (x) an amalgamation, consolidation, statutory arrangement (involving a business combination), amendment to articles, merger, or similar transaction of Inco in which the holders of the voting securities of Inco immediately prior to the amalgamation, consolidation, statutory arrangement, merger, or similar transaction have, directly or indirectly, more than 50% of the voting securities of the continuing or surviving corporation immediately after such transaction is consummated, or (y) in connection with any of the Transactions or any Subsequent Amalgamation.”

          The amount of “US$500,000,000” referred to in section 5.04(g) is hereby deleted and “US$750,000,000” inserted in replacement thereof.

          Promptly following your execution and delivery of this Waiver and Amendment Letter, you shall execute and deliver an amendment, in form and substance acceptable to you, us

           and the other lenders, each acting reasonably, to the Existing Credit Agreement to provide for the following:

(i)

	(ii)		that (A) the Debt incurred in connection with the Transactions, any repayment or refinancing of debt or redemption of preferred shares in connection therewith, and all payments of fees, commissions, and expenses in connection therewith (collectively, the Non-Dissent Transactions) for which the Borrower is liable shall not at any time exceed US$6.3 billion (of which no more than US$5.5 billion shall be senior Debt) and (B) if dissent or appraisal rights are exercised in connection with the Transactions, the aggregate amount of Debt incurred in connection with (I) the payment of fair value for Falconbridge Common Shares pursuant to such rights and the payment of expenses in connection therewith (collectively, the “Dissent Transactions”) and (II) the Non-Dissent Transactions for which the Borrower is liable shall not at any time exceed US$9.3 billion and (C) the Borrower shall not at any time be liable for any Debt incurred in connection with the Non-Dissent Transactions or the Dissent Transactions other than (I) advances under the Delivery Letter Financing Arrangements (as hereinafter defined) and the Existing Credit Agreement and bond debt applied to prepay such advances or terminate commitments to provide such advances and (II) the Portugal Convertible Debt;
	(iii)		that the sources and uses of funds in connection with the Transactions shall be as set out in the letter in form and substance satisfactory to us delivered to us contemporaneously with the execution of this Waiver and Amendment Letter;
	(iv)		if, on any date the Borrower’s credit rating by any two of Moody’s, S&P and Fitch is BB (or equivalent) or lower (either such event, a “Credit Rating Downgrade”), a consolidated fixed charge covenant ratio to be set at a level acceptable to you, us and the other applicable lenders, each acting reasonably; and
	(v)		if, on any date a Credit Rating Downgrade occurs, the Borrower shall, no later than the date that is 2 months from such date, grant to the Lenders first ranking security over all of its assets (subject to carve outs and exclusions agreed to by us,

acting reasonably) located in the United States of America and Canada to secure the Borrower’s obligations under the relevant facility and shall cause each of its subsidiaries located in the United States of America and Canada (including, without limitation, Bird and its subsidiaries) to guarantee the Borrower’s obligations under the relevant facility and to secure such guarantee by granting first ranking security over all of its assets (subject to carve outs and exclusions agreed to by us, acting reasonably) located in the United States of America and Canada. Such security and guarantees shall be in form and substance satisfactory to the administrative agent of each such facility, acting reasonably. The Lenders, the lenders under the financing arrangements contemplated by the Delivery Letter dated May 13, 2006 between you and us, as amended from time to time (the “Delivery Letter Financing Arrangements”), and to the extent required under bonds and other debt instruments issued prior to the date hereof by the Borrower and Bird, the holders of such instruments shall share such security rateably. Such security shall by its terms release as of the Borrower attaining a credit rating higher than BB (or equivalent) from any two of Moody’s, S&P and Fitch. Such security and guarantees will not necessarily apply in respect of bonds issued after the date hereof.

             For certainty, no Advance shall be available under the Existing Credit Agreement until such amendment has been executed and delivered.
