STATEMENTS REGARDING FORWARD-LOOKING INFORMATION

This Notice of Variation and some of the material incorporated by reference into this Notice of Variation contain certain "forward-looking statements" as well as forward-looking information within the meaning of theSecurities Act (Ontario). Forward-looking statements can be identified by the use of words such as "plans", "expects" or "does not expect", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate", or "believes", or variation of such words and phrases or state that certain actions, events or results "may", "could", "should", "would", "might" or "will" be taken, occur or be achieved. Forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of Teck or Inco to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. These forward-looking statements include estimates, forecasts, and statements as to management's expectations concerning Teck, including after its proposed acquisition of Inco, with respect to, among other things, the size and quality of Teck's development projects, mineral reserves and mineral resources, future trends, plans, strategies, objectives and expectations, including with respect to future operations, products, services and projects for Teck, the proposed integration of management of Teck and Inco, progress in development of mineral properties, future production, capital and mine production costs,

demand and market outlook for commodities, future commodity prices and treatment and refining charges, the application of Teck's CESL technology in Inco's operations, expected synergies and cost savings from the proposed acquisition of Inco, including the timing thereof, and the financial results, cash flows and operations of Teck and Inco, including following Teck's proposed acquisition of Inco. These forward-looking statements involve numerous assumptions, risks and uncertainties and actual results may vary materially.

These statements are based on a number of assumptions, including, among others, assumptions regarding general business and economic conditions, interest rates, the supply and demand for, deliveries of, and the level and volatility of prices of nickel, cobalt, platinum group metals, zinc, copper, coal and gold and other primary metals and minerals as well as oil, natural gas and petroleum products produced by Teck and Inco, the timing of the receipt of regulatory and governmental approvals for Teck's and Inco's development projects and other operations, the availability of financing for Teck's and Inco's development projects on reasonable terms, Teck's and Inco's respective costs of production and their respective production and productivity levels, as well as those of their competitors, power prices, market competition, the accuracy of Teck's and Inco's reserve estimates (including, with respect to size, grade and recoverability) and the geological, operational and price assumptions on which these are based, future commodity prices, production of commodities by Teck, Inco and their respective competitors, the realization of synergies, transaction costs, and the future financial performance of Teck and Inco.

The foregoing list of assumptions is not exhaustive. Events or circumstances could cause actual results to differ materially. Factors that may cause actual results to vary include, but are not limited to: the Teck Subordinate Voting Shares issued in connection with the proposed acquisition may have a market value lower than expected, the businesses of Teck and Inco may not be integrated successfully or such integration may be more difficult, time-consuming or costly than expected, the expected combination benefits and synergies and cost savings from the Teck/Inco transaction may not be fully realized or not realized within the expected time frame, the possible delay in the completion of the steps required to be taken for the eventual combination of the two companies, business and economic conditions in the principal markets for the companies' products, the supply, demand, and prices for metals to be produced, changes in commodity and power prices, changes in interest and currency exchange rates, inaccurate geological and metallurgical assumptions (including with respect to the size, grade and recoverability of mineral reserves and resources), unanticipated operational difficulties (including failure of plant, equipment or processes to operate in accordance with specifications or expectations, cost escalation, unavailability of materials and equipment, government action or delays in the receipt of government approvals, industrial disturbances or other job action, and unanticipated events related to health, safety and environmental matters), political risk, social unrest, changes in general economic conditions or conditions in the financial markets and other risk factors related to the mining and metals industry as detailed from time to time in Teck's and Inco's reports filed with the SEC.

Certain of these risks are described in more detail in the annual information form of Teck and in its public filings with the SEC. Teck does not assume the obligation to revise or update these forward-looking statements after the date of this document or to revise them to reflect the occurrence of future unanticipated events, except as may be required under applicable securities laws.

Except as otherwise indicated, the information concerning Inco contained in this Notice of Variation has been taken from or is based upon publicly available documents and records on file with Canadian securities regulatory authorities, the SEC and other public sources. Although Teck has no knowledge that would indicate that any statements contained herein concerning Inco taken from or based upon such documents and records are untrue or incomplete, neither Teck nor any of its directors or officers assumes any responsibility for the accuracy or completeness of such information, including any of Inco's financial statements, or for any failure by Inco to disclose events or facts which may have occurred or which may affect the significance or accuracy of any such information but which are unknown to Teck. Teck has no means of verifying the accuracy or completeness of any of the information contained herein that is derived from Inco's publicly available documents or records or whether there has been any failure by Inco to disclose events that may have occurred or may affect the significance or accuracy of any information.

NOTICE OF VARIATION

August 3, 2006

TO: THE SHAREHOLDERS OF INCO

This Notice of Variation amends and supplements the Offer and Circular dated May 23, 2006, as amended by the First Variation dated July 24, 2006, pursuant to which the Offeror is offering to purchase, on the terms and subject to the conditions contained therein, all of the outstanding Inco Shares, other than any Inco Shares owned, directly or indirectly, by the Offeror and its affiliates on any Take-Up Date, and including any Inco Shares that may become issued and outstanding after the date of this Notice of Variation but prior to the Expiry Time upon the conversion, exchange or exercise of any securities of Inco (other than Rights) that are convertible into or exchangeable or exercisable for Inco Shares.

Except as otherwise set forth in this Notice of Variation, the terms and conditions previously set forth in the Offer and Circular and the First Variation continue to be applicable in all respects. This Notice of Variation should be read in conjunction with the Offer and Circular, the First Variation, the replacement Letter of Transmittal and the replacement Notice of Guaranteed Delivery.

All references to the "Offer" in the Offer and Circular, the replacement Letter of Transmittal, the replacement Notice of Guaranteed Delivery and this Notice of Variation mean the Original Offer as amended by the First Variation and this Notice of Variation, and all references in such documents to the "Circular" mean the Original Circular as amended by the First Variation and this Notice of Variation. Capitalized terms used in this Notice of Variation and not defined herein that are defined in the Offer and Circular have the respective meanings ascribed thereto in the Offer and Circular.

1. Amendment of Offered Consideration

The Offeror has varied the Offer by amending the consideration offered to Shareholders from, at the election of each holder of Inco Shares, (a) $78.50 in cash, or (b) 0.9776 of a Teck Subordinate Voting Share and $0.05 in cash for each Inco Share, subject in each case to pro ration, to, at the election of each holder of Inco Shares, (a) $82.50 in cash, or (b) 1.1293 Teck Subordinate Voting Shares and $0.05 in cash for each Inco Share, subject in each case to pro ration. Accordingly, the definitions of "Cash Alternative" and "Share Alternative" in the Offer and Circular (found at pages 7 and 12, respectively, of the Offer and Circular) are deleted and replaced by the following, respectively:

"Cash Alternative" means $82.50 in cash for each Inco Share, subject to pro ration as set out herein.

"Share Alternative" means 1.1293 Teck Subordinate Voting Shares and $0.05 in cash for each Inco Share, subject to pro ration as set out herein.

All references in the Offer and Circular and the First Variation to the price offered by the Offeror are amended to reflect the foregoing changes.

The Maximum Cash Consideration has been increased to $9,091,281,360 and the Maximum Share Consideration has been reduced to 132,303,608 Teck Subordinate Voting Shares. Accordingly, the definitions of "Maximum Cash Consideration" and "Maximum Share Consideration" in the Offer and Circular (found at page 10 of the Offer and Circular) are deleted and replaced by the following, respectively:

"Maximum Cash Consideration" means $40.00 multiplied by the number of Inco Shares To Which The Bid Relates. Based on the number of Inco Shares outstanding on a fully diluted basis as of June 30, 2006, the Maximum Cash Consideration is $9,091,281,360.

"Maximum Share Consideration" means 0.5821 multiplied by the number of Inco Shares To Which The Bid Relates. Based on the number of Inco Shares outstanding on a fully diluted basis as of June 30, 2006, the Maximum Share Consideration is 132,303,608 Teck Subordinate Voting Shares.

All references in the Offer and Circular and the First Variation to the Maximum Cash Consideration and the Maximum Share Consideration offered by the Offeror are amended to reflect the foregoing changes.

Assuming that either all Shareholders tendered to the Cash Alternative or all Shareholders tendered to the Share Alternative, after the effect of pro ration, each Shareholder would be entitled to receive $40.00 in cash and 0.5821 of a Teck Subordinate Voting Share for each Inco Share tendered, subject to adjustment for fractional shares. In light of the total amount of cash available under the Offer relative to the size of the Offer, it is unlikely that Shareholders who elect to receive the Cash Alternative will receive only cash consideration for their Inco Shares.

All references in the Offer and Circular and the First Variation to the amount of cash and Teck Subordinate Voting Shares that would be received assuming that either all Shareholders tendered to the Cash Alternative or all Shareholders tendered to the Share Alternative, are amended to reflect the foregoing.

On July 28, 2006, the last trading day prior to the Offeror's announcement of its intention to amend the consideration offered for the Inco Shares, the closing price of the Teck Subordinate Voting Shares on the TSX and NYSE was Cdn.$73.01 and U.S.$64.87, respectively, and the closing price of the Inco Shares on the TSX and NYSE was Cdn.$86.57 and U.S.$76.40, respectively. The volume-weighted average trading price of the Inco Shares on the TSX for the 30 trading days ended July 28, 2006 was Cdn.$76.12. The volume-weighted average trading price of the Inco Shares on the NYSE for the 30 trading days ended July 28, 2006 was U.S.$66.53. The Offer price of Cdn.$82.50 per Inco Share represents a premium of approximately 8.4% and a discount of approximately 4.7% to the 30 trading day volume-weighted average trading price and the closing price, respectively, of the Inco Shares on the TSX as at July 28, 2006 and a premium of approximately 9.6% and a discount of approximately 4.6% to the 30 trading day volume-weighted average trading price and the closing price, respectively, of the Inco Shares on the NYSE as at July 28, 2006.

Assuming that all of the conditions to the Offer are satisfied or waived, all Shareholders whose Inco Shares are taken up under the Offer, including Shareholders who have already deposited their Inco Shares to the Offer, will receive the amended consideration for their Inco Shares.

2. Amendments to Pro Forma Financial Information

The Summary of Teck and Inco Historical and Pro Forma Financial Information in the "Summary of the Offer" (found at pages 21-23 of the Offer and Circular) is deleted and replaced by the following:

SUMMARY OF TECK AND INCO
HISTORICAL AND PRO FORMA FINANCIAL INFORMATION

The following tables present a summary of certain historical audited consolidated financial information in respect of each of Teck and Inco as at and for the years ended December 31, 2005 and 2004 and certain historical unaudited consolidated financial information of Teck and Inco as at and for the six months ended June 30, 2006 and 2005. Teck's financial statements as at and for such periods are incorporated by reference in this Offer and Circular. Copies of Teck's financial statements and related notes incorporated herein by reference can be found atwww.sedar.com andwww.sec.gov.

The historical information presented for Inco is derived from the audited consolidated financial statements of Inco as at and for the years ended December 31, 2005 and 2004, which statements are incorporated by reference in this Offer and Circular, and from the unaudited consolidated financial statements of Inco as at and for the six months ended June 30, 2006 and 2005. Copies of Inco's financial statements and related notes incorporated by reference herein can be found atwww.sedar.com andwww.sec.gov.

The tables also present Teck's pro forma consolidated financial information as at and for the six months ended June 30, 2006 and for the year ended December 31, 2005 after giving effect to Teck's acquisition of all of the Inco Shares pursuant to the Offer. This information is derived from and should be read in conjunction with the financial statements of each of Teck and Inco and the related notes to those financial statements incorporated by reference herein and in conjunction with the unaudited consolidated financial statements of Inco as at and for the six months ended June 30, 2006 and 2005. The summary pro forma consolidated financial information set forth below should also be read in conjunction with Teck's unaudited pro forma consolidated financial statements, the accompanying notes thereto and the compilation report of PricewaterhouseCoopers LLP thereon included in this Notice of Variation. The pro forma consolidated

balance sheet has been prepared from the unaudited consolidated balance sheet of each of Teck and Inco as at June 30, 2006 and gives pro forma effect to the acquisition of Inco by Teck as if the transaction occurred on June 30, 2006. The pro forma consolidated statements of earnings for the six month period ended June 30, 2006 and for the year ended December 31, 2005 have been prepared from the unaudited statements of earnings of each of Teck and Inco for the six months ended June 30, 2006 and from the audited statements of earnings of each of Teck and Inco for the year ended December 31, 2005 and gives pro forma effect to the acquisition of Inco by Teck as if the transaction occurred on January 1, 2005.

In preparing the unaudited pro forma consolidated financial statement information, management of the Offeror has made certain assumptions that affect the amounts reported in the unaudited pro forma consolidated financial statement information. The summary unaudited pro forma consolidated financial information is not intended to be indicative of the results that would actually have occurred, or the results expected in future periods, had the events reflected herein occurred on the dates indicated. Actual amounts recorded upon consummation of the transaction contemplated by the Offer will differ from the pro forma information presented below.As Teck only has access to Inco's publicly available information, no attempt has been made to calculate or estimate the effect of harmonization of accounting policies or practices between Teck and Inco.

Shareholder Rights Plan

On July 20, 2006, with the consent of Teck and Inco, the Ontario Securities Commission issued a cease-trade order with respect to any securities issued or to be issued under or in connection with the Rights Plan, effective as of 4:30 p.m. (Toronto time) on August 16, 2006.

Teck Financial Results for the Three Months Ended June 30, 2006

On July 24, 2006, Teck reported unaudited net earnings for the second quarter of 2006 of $613 million or $2.95 per share, up significantly from net earnings of $225 million or $1.11 per share in the second quarter of 2005. The significantly higher earnings in the second quarter were a result of higher prices for Teck's products. Average London Metal Exchange cash prices for copper and zinc were U.S.$3.27 and U.S.$1.49 per pound, respectively, in the quarter, up significantly from U.S.$1.54 and U.S.$0.58 per pound, respectively, in the second quarter in 2005. Coal prices averaged U.S.$116 per tonne in the second quarter of 2006 compared with U.S.$94 per tonne a year ago. A lower U.S./Canadian dollar exchange rate of $1.00/$1.12 in the second quarter compared with $1.00/$1.24 a year ago partially offset the higher commodity prices.

Teck's net earnings in the first half of the year were $1.1 billion, more than double the net earnings of $430 million in the first half of 2005, as a result of higher commodity prices. Net earnings in the first two quarters of the year are typically lower than the last two quarters, due to the seasonality of shipments from Teck's Red Dog mine in Alaska. Red Dog's zinc sales in the first half of 2006 accounted for approximately 32% of its planned annual sales. Coal sales volumes at Elk Valley Coal Partnership in the first half of 2006 were approximately 45% of planned sales volumes for the year. For further detail regarding Teck's financial results, please refer to the Unaudited Consolidated Interim Financial Statements and related notes thereto for the six months ended June 30, 2006 and 2005 and Management's Discussion and Analysis of Financial Position and Operating Results related thereto, which are incorporated by reference herein.

Termination of Inco/Falconbridge Support Agreement

On July 27, 2006, Inco's offer to acquire all the outstanding shares of Falconbridge expired. On July 28, 2006, Falconbridge announced that the support agreement between Inco and Falconbridge had been terminated.

8. Replacement Letter of Transmittal and Replacement Notice of Guaranteed Delivery

Shareholders will not be required to pay any fee or commission if they accept the Offer by depositing their Inco Shares directly with the Depositary or the U.S. Forwarding Agent or if they make use of the services of a member of the Soliciting Dealer Group to accept the Offer.

The Original Offer was accompanied by a Letter of Transmittal (printed on green paper) and a Notice of Guaranteed Delivery (printed on yellow paper) to accept the Offer. Shareholders may continue to use the original Letter of Transmittal or the original Notice of Guaranteed Delivery to accept the Offer, in which case the original Letter of Transmittal or the original Notice of Guaranteed Delivery, as the case may be, shall be deemed to be amended to reflect the terms and conditions of the replacement Letter of Transmittal and replacement Notice of Guaranteed Delivery and of the Offer as amended and supplemented by the First Variation and this Notice of Variation.

However, such rights must be exercised within prescribed time limits. Holders of Inco Shares should refer to the applicable provisions of the securities legislation of their province or territory for particulars of those rights or consult with a lawyer.

The foregoing, together with the Offer and Circular, contains no untrue statement of a material fact and does not omit to state a material fact that is required to be stated or that is necessary to make a statement not misleading in the light of the circumstances in which it was made.

ANNEX A

NOTE: The following compilation report is provided solely to comply with the applicable requirements of Canadian securities laws. The Canadian auditing standards specify the procedures that should be performed which are outlined in the report. These procedures would not be sufficient to allow for an expression of opinion under the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"). The procedures that would be performed to allow for an expression of an opinion under the standards of the PCAOB would be more extensive and greater in scope than that required by the Canadian auditing standards. Accordingly, no opinion is expressed on the pro forma information under the standards of the PCAOB.

PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS OF TECK COMINCO LIMITED

The following selected unaudited pro forma consolidated financial information is presented for illustrative purposes only and is not necessarily indicative of the operating results or financial condition of the consolidated entities that would have been achieved if the Offer had been completed during the periods presented, nor is the selected pro forma consolidated financial information necessarily indicative of the future operating results or financial position of the consolidated entities.

COMPILATION REPORT ON PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

To the Directors of Teck Cominco Limited

We have read the accompanying unaudited pro forma consolidated balance sheet of Teck Cominco Limited (the "company" or "Teck") as at June 30, 2006 and the unaudited pro forma consolidated statements of earnings for the six months then ended and for the year ended December 31, 2005, and have performed the following procedures.

1.

Compared the figures in the columns captioned "Teck" to the unaudited consolidated financial statements of the company as at June 30, 2006 and for the six months then ended, and the audited consolidated financial statements of the company for the year ended December 31, 2005 respectively, and found them to be in agreement.

2.

Compared the figures in the columns captioned "Inco US$" to the unaudited consolidated financial statements of Inco Limited as at June 30, 2006 and for the six months then ended and the audited consolidated financial statements of Inco Limited for the year ended December 31, 2005 respectively, and found them to be in agreement.

3.

Made enquiries of certain officials of the company who have responsibility for financial and accounting matters about:

(a): the basis for determination of the pro forma adjustments; and
(b): whether the pro forma consolidated financial statements comply as to form in all material respects with the regulatory requirements of the various Securities Commissions and similar regulatory authorities in Canada.

The officials:

(a): described to us the basis for determination of the pro forma adjustments, and
(b): stated that the pro forma consolidated financial statements comply as to form in all material respects with the regulatory requirements of the various Securities Commissions and similar regulatory authorities in Canada.

4.: Read the notes to the pro forma consolidated financial statements, and found them to be consistent with the basis described to us for determination of the pro forma adjustments.
5.: Recalculated the application of the pro forma adjustments to the aggregate of the amounts in the columns captioned "Teck" and "Inco CDN$" as at June 30, 2006 and for the six months then ended,

A-1

and for the year ended December 31, 2005, and found the amounts in the columns captioned "Pro forma Teck" to be arithmetically correct.

A pro forma financial statement is based on management assumptions and adjustments which are inherently subjective. The foregoing procedures are substantially less than either an audit or a review, the objective of which is the expression of assurance with respect to management's assumptions, the pro forma adjustments, and the application of the adjustments to the historical financial information. Accordingly, we express no such assurance. The foregoing procedures would not necessarily reveal matters of significance to the pro forma consolidated financial statements, and we therefore make no representation about the sufficiency of the procedures for the purposes of a reader of such statements.

These unaudited pro forma consolidated financial statements (pro forma financial statements) of Teck Cominco Limited (Teck) have been prepared in accordance with generally accepted accounting principles in Canada. These pro forma financial statements do not contain all of the information required for annual financial statements. Accordingly they should be read in conjunction with the most recent annual and interim financial statements of Teck, and the most recent annual and interim financial statements of Inco Limited (Inco).

These pro forma financial statements have been prepared assuming that the acquisition of Inco had been completed on January 1, 2005 for the unaudited pro forma consolidated statements of earnings and on June 30, 2006 for the unaudited pro forma consolidated balance sheet.

These pro forma financial statements are not intended to reflect the financial position which would have resulted had the transaction actually been affected on June 30, 2006 or the results of operations had the transaction been effected on January 1, 2005. Further, the pro forma results of operations may not be indicative of future results.

2. SIGNIFICANT ACCOUNTING POLICIES

Accounting policies used in the preparation of these pro forma financial statements are those disclosed in Teck's audited consolidated financial statements for the year ended December 31, 2005 and Teck's unaudited consolidated financial statements for the six months ended June 30, 2006. As Teck only has access to Inco's publicly available information, no calculations or estimates have been made to harmonize the accounting policies of Teck and Inco.

For the purposes of these pro forma financial statements, the Inco balance sheet as at June 30, 2006 has been translated into Canadian dollars at the period end rate of 1.1150, the Inco statement of earnings for the year ended December 31, 2005 has been translated at an average rate of 1.2116 and the Inco statement of earnings for the six months ended June 30, 2006 has been translated at an average rate of 1.1384.

3. PRO FORMA ADJUSTMENTS

The acquisition of Inco by Teck is accounted for using the purchase method. Accordingly, Inco's assets and liabilities are measured at their individual fair values on the date of the acquisition and the difference between these fair values and the price paid for Inco shares is recorded on the balance sheet as goodwill. Inco's shareholders' equity is eliminated upon consolidation. Teck's assets and liabilities are not revalued as part of this process.

The pro forma financial statements assume the completion of a business combination whereby 227.3 million shares of Inco at June 30, 2006 calculated on a fully-diluted basis are acquired for total consideration of $18,268 million, comprising 132.3 million subordinate voting shares of Teck, and $9,091 million in cash. For the purpose of these pro forma financial statements, Teck has assumed that the maximum cash component of the Offer will be reached. The final amount of the cash portion of the consideration will depend on decisions relating to the exercise of options made by holders of Inco stock options, the conversion, if any, of Inco's convertible debentures, and elections made by shareholders of Inco on acceptance of the Offer.

The measurement of the purchase consideration in the pro forma financial statements is based on a Teck subordinate voting share price of $73.01 at the time of the Offer. The actual measurement date of the purchase consideration will occur on the date when sufficient shares have been tendered to make the Offer binding. The value of the purchase consideration will be based on the market price of Teck shares at the time the Offer closes. Consequently, the eventual value of the purchase consideration for accounting purposes will differ from the amount assumed in the pro forma financial statements due to any future changes in the market price of Teck's subordinate voting shares.

The allocation of the purchase price to the assets and liabilities of Inco as presented in these pro forma financial statements is preliminary and subject to change. In arriving at the fair values of assets and liabilities Teck has made assumptions, estimates and assessments which are based on limited information. The actual fair values of the assets and liabilities will be determined as of the date of the acquisition, not the dates used in the preparation of these pro forma financial statements. The amounts determined may differ materially from the amounts disclosed in the purchase price allocation set out in (d) below due to changes in the estimates of fair values of the assets and liabilities as more information is available for assessment. Any such changes in the determination and allocation of the purchase price could also result in changes to the adjustments to earnings in subsequent periods.

The pro forma adjustments reflect Teck's acquisition of 100% of Inco's assets and liabilities at their fair values and the accounting for Inco as a wholly owned subsidiary.

A-6

Balance Sheet Adjustments:

Adjustments related to the pro forma consolidated balance sheet as at June 30, 2006 have been made as follows:

(a)

The following adjustments have been made to reflect the book value of Inco at the date of acquisition:

i.: to give effect to proceeds of $409 million deemed to be received by Inco on the exercise of in-the-money warrants and employee and director share options;
ii.: to give effect to the conversion of all outstanding Inco convertible debt instruments to common shares of Inco;

(b)

To record the settlement of the Inco exchangeable debentures previously issued by Teck with shares of Inco currently held by Teck.

(c)

To record the purchase of Inco shares for cash and Teck shares as follows:

(C$ millions)
Cash portion of the Offer	$	9,091
Issue of 132.3 million Teck subordinate voting shares⁽¹⁾		9,177

		18,268
Estimated transaction fees including net break fees and expenses of Teck and Inco		435
Cost of investment in Inco at June 30, 2006		191

Total purchase price	$	18,894

(1): The purchase price was calculated using a price of $73.01 for each Teck subordinate voting share issued, net of deemed issue costs.

(d): The following allocates the purchase price based on management's preliminary estimate of fair values after giving effect to (a) above:

(C$ millions)	Inco Book Value		Fair Value Adjustments		Inco Fair Value
Cash and cash equivalents	$	1,178	$	—	$	1,178

(e): To record the proceeds of the additional $5.390 billion debt and the conversion of $350 million of temporary investments into cash to finance the acquisition. Teck has arranged bridge financing facilities of US$5.85 billion. Teck plans to draw on this facility together with cash and temporary investments on hand to finance the transaction. A portion of the drawn facility is assumed to be repaid from Inco's cash balances immediately following the transaction.
(f): To eliminate the investment in Inco on consolidation.

A-7

Income Statement Adjustments:

(g): To eliminate the amortization of unamortized transitional adjustments and past service costs related to defined benefit pensions and other post-retirement benefits of Inco.
(h): To depreciate and amortize the preliminary fair value adjustments allocated to property, plant and equipment. An amount of $4.3 billion has been allocated to non-amortizable assets. To the extent that this amount is allocated to property, plant and equipment, amortization charges may increase. Any amount allocated to goodwill will be subject to impairment tests and may be written off in future periods. In addition, an amount of $11.8 billion has been allocated to assets, including Voisey's Bay and Goro, which were not in production in 2005 ($6 billion has been allocated to assets which were not in production in the first half of 2006).
(i): To adjust interest expense and interest income to reflect changes in Teck's debt structure, including additional debt incurred as a result of the transaction, the conversion and redemption of certain Inco and Teck debt instruments, fair value adjustments to Inco debt and the reduction of cash balances resulting from the transaction.
(j): To provide for taxes on the above items.

4. ITEMS NOT ADJUSTED

The adjustments made to the pro forma consolidated statements of earnings reflect only those items which are expected to recur and do not include one time charges to income which are expected to occur immediately following the transaction. In addition, the pro forma consolidated statements of earnings do not give effect to operating efficiencies, cost savings and synergies that may result from the acquisition, including potential cost savings at the corporate level and potential synergies in exploration activities and at operations.

Total liabilities and shareholders' equity		$	36,730	$	(40	)	$	36,690

(a): Convertible Debentures

Under Canadian GAAP the convertible debentures due 2024, redeemed on June 1, 2006, were classified as equity with related interest being charged directly to retained earnings. For US GAAP purposes, interest on these debentures would be charged against current period earnings.

(b): Share of Earnings in Fording Canadian Coal Trust (FCCT)

The company accounts for its share of earnings of FCCT on an equity basis. Adjustments in respect of the company's share of earnings in FCCT arise due to various differences between US and Canadian GAAP in the underlying entity.

(c): Unrealized Holding Gains on Investments

Under Canadian GAAP, the company's marketable securities are carried at cost. For US GAAP purposes, the company's marketable securities are considered to be available-for-sale. Available-for-sale securities are carried at market value with unrealized gains or losses included in comprehensive income until realized or until an other than temporary decline occurs.

(d): Deferred Start-Up Costs

Under Canadian GAAP, certain mine start-up costs are deferred until the mine reaches commercial levels of production and are amortized over the life of the project. Under US GAAP, these costs are expensed as incurred.

(e): Research and Development Expense

Under Canadian GAAP, development costs are deferred and amortized if the development project meets certain generally accepted criteria for deferral and amortization. In addition, fixed assets including equipment may be acquired or constructed in order to provide facilities or carry out a research and development project. The use of such assets will extend over a number of accounting periods and accordingly, are capitalized and amortized over their useful lives. Under US GAAP, research and development costs are charged to expense in the period incurred.

A-11

(f): Exploration Expense

Under Canadian GAAP, capitalized exploration expenditures are classified under property, plant and equipment with the related mineral claim. For US GAAP, exploration expenditures are not capitalized unless proven and probable reserves have been established by a feasibility study.

(g): Comprehensive Income

Under US GAAP, comprehensive income is recognized and measured in accordance with FASB Statement No. 130, "Reporting Comprehensive Income". Comprehensive income includes all changes in equity other than those resulting from investments by owners and distributions to owners. Comprehensive income includes two components, net income and other comprehensive income (OCI). OCI includes amounts that are recorded as an element of shareholders' equity but are excluded from net income as these transactions or events were attributable to changes from non-owner sources. These items include additional minimum pension liability adjustments, holding gains and losses on certain investments, gains and losses on certain derivative instruments and foreign currency gains and losses related to self-sustaining foreign operations (cumulative translation adjustment). A standard for comprehensive income is not yet effective under Canadian GAAP.

(h): Derivative Instruments

Under Canadian GAAP, derivative instruments to which hedge accounting is applied are held off-balance sheet with realized gains and losses recorded in net earnings. Non-hedge derivative instruments must be recorded on the balance sheet at fair value with changes in fair value recorded in other income.

For US GAAP purposes, all derivatives are recorded on the balance sheet as either assets or liabilities at fair value. The accounting for changes in the fair value of derivatives depends on whether the derivative has been designated as a fair value or cash flow hedge and whether it qualifies as part of a hedging relationship.

For fair value hedges, the effective portion of the changes in fair value of the derivatives is offset by changes in the fair value of the hedged item in net earnings. For cash flow hedges the effective portion of the changes in fair value are accumulated in other comprehensive income and released into net earnings when the hedged item affects net earnings. For derivatives not accounted for as part of a hedging relationship, changes in fair value are included in net earnings.

(i): Asset Retirement Obligations

For US GAAP purposes the company adopted FASB Statement No. 143, "Accounting for Asset Retirement Obligations", effective January 1, 2003. The company adopted the provisions of CICA 3110, "Asset Retirement Obligations", for Canadian GAAP purposes effective January 1, 2004.

The Canadian and US standards for Asset Retirement Obligations are substantially the same; however, due to the difference in adoption dates, different discount rate assumptions were used. This resulted in differences in the asset and liability balances on adoption and will result in different amortization and accretion charges over time.

(j): Additional Minimum Pension Liability

For US GAAP purposes, the company is required to recognize an additional minimum pension liability in the amount of the excess of the company's unfunded accrued benefit obligation over the fair value of the plan assets. An intangible asset is recorded equal to any unrecognized past service costs. Changes in the additional minimum pension liability and intangible asset are recorded in other comprehensive income.

(k): Capitalized Interest

For US GAAP purposes, interest costs must be capitalized for all assets that are under development. For Canadian GAAP, the company capitalizes interest only on project specific debt.

(l): Unrealized Currency Translation Gains (Losses) on Voisey's Bay Project Deferred Income and Mining Tax Liabilities

For the purpose of these pro forma financial statements, Inco is considered to be a self sustaining foreign entity whose functional currency is the US dollar. For US GAAP purposes, unrealized non-cash currency translation gains and losses arising from the translation into United States dollars, at the end of each period, of certain Canadian dollar-denominated deferred income and mining tax liabilities established in 1996 upon the acquisition of the Voisey's Bay deposits are included in the determination of earnings. Under Canadian GAAP, these unrealized non-cash currency translation gains and losses have been

A-12

deferred and included in property, plant and equipment as part of development costs for the Voisey's Bay project until operations commence.

(m): Deferred Stripping Costs

Effective January 1, 2006, under Canadian GAAP, the company adopted EIC 160 "Stripping Costs Incurred in the Production Phase of a Mining Operation", and under US GAAP, EITF 04-6 "Accounting for Stripping Costs Incurred During Production in the Mining Industry". Both standards require stripping costs to be accounted for as a variable production cost to be included in the costs of inventory produced during the production phase.

Under Canadian GAAP, the company has elected to use prospective adoption, and amortizes the existing balance sheet amount relating to deferred stripping costs over the reserves to which it relates. Under US GAAP, the company has retroactively adopted EITF 04-06, whereby the cumulative effect of the adjustment is recognized in the opening balance of retained earnings. This resulted in an initial US GAAP difference to decrease property, plant and equipment by $52 million, decrease future income tax liability by $22 million and decrease retained earnings by $30 million.

Canadian GAAP permits capitalization of stripping activity which represents a betterment of a mineral property. Betterment occurs when the stripping activity increases future output of the mine by providing access to additional sources of reserves. Capitalized stripping costs are amortized on a unit of production basis over the proven and probable reserves to which they relate. Under US GAAP, all stripping costs are treated as variable production costs.
