 AND TO:	
 	

CIBC MELLON TRUST COMPANY (the "Depositary") or MELLON INVESTOR SERVICES LLC (the "U.S. Forwarding Agent"), at its offices set out herein

        The
undersigned delivers to you the enclosed certificate(s) representing Common Shares and Rights, if applicable, subject only to the provisions of the Offer regarding withdrawal. The
undersigned irrevocably accepts the Offer for such Common Shares and Rights upon the terms and conditions contained in the Offer. The undersigned understands that by depositing Common Shares to the
Offer the undersigned will be deemed to have deposited the Rights associated with such Common Shares. No additional payment will be made for the Rights and no amount of the consideration to be paid by
the Offeror will be allocated to the Rights. Unless waived by the Offeror, holders of Common Shares are required to deposit one Right for each Common Share in order to effect a valid deposit of such
Common Share or, if available a book-entry confirmation must be received by the Depositary with respect thereto. The following are the details of the enclosed certificate(s):

have been delivered to holders of Common Shares, specify certificates representing Rights in this Box. Note that in any case, a deposit of Common Shares constitutes an agreement by the undersigned to deliver Rights certificate(s) representing Rights
equal in number to the number of deposited Common Shares to the Depositary or the U.S. Forwarding Agent, as applicable within three trading days on the Toronto Stock Exchange (the "TSX") after the date, if any, that Rights certificate(s) are
distributed. The Offeror reserves the right to require, if the Separation Time occurs before the Expiry Time, that the Depositary receive, prior to taking up the Common Shares for payment pursuant to the Offer, Rights certificate(s) from the
undersigned representing Rights equal in number to the Common Shares deposited.

BOX 2

ELECTION FOR CASH OR SHARES	

 
	
Pursuant to the Offer, the undersigned hereby elects to receive one of the following forms of consideration for all of the deposited Inco Shares represented by the certificate(s) listed in Box 1
above. Shareholders may elect to receive either the Cash Alternative (Choice A) OR the Share Alternative (Choice B).	

 
	
Shareholders may choose only ONE of the choices below:	

 
	
 o  Choice A — The CASH ALTERNATIVE	

 
	
Shareholders who check this box will receive Cdn.$82.50 in cash for each Inco Share deposited under this Choice A (subject to pro ration and subject to the election made in
Box 3 below with respect to currency of payment)	

 
	
o  Choice B — The SHARE ALTERNATIVE	

 
	
Shareholders who check this box will receive 1.1293 Class B subordinate voting shares of Teck Cominco Limited (a "Teck Subordinate Voting Share") and Cdn.$0.05 in cash for each Inco
Share deposited under this Choice B (subject to pro ration and subject to the election made in Box 3 below with respect to currency of payment)	

 
	
If a Shareholder fails to elect the Cash Alternative or does not properly elect either the Cash Alternative, on the one hand, or the Share Alternative, on the other hand, with respect to any Inco
Shares deposited by it pursuant to the Offer, such Shareholder will be deemed to have elected the Share Alternative and will be entitled to receive only 1.1293 Teck Subordinate Voting Shares and Cdn.$0.05 in cash as consideration for each of such
Shareholder's Inco Shares, subject to pro ration as described in Section 1 of the Offer, "The Offer".	

 
	

Fractional Teck Subordinate Voting Shares will not be issued in connection with the Offer. Where on any Take-Up Date a Shareholder is to receive Teck Subordinate Voting Shares as consideration pursuant to the Offer and the aggregate number of Teck
Subordinate Voting Shares to be issued to such Shareholder would result in a fraction of a Teck Subordinate Voting Share being issuable, the number of Teck Subordinate Voting Shares to be received by such Shareholder will be rounded down and in lieu
of a fractional Teck Subordinate Voting Share, the Shareholder will receive a cash payment determined on the basis of an amount equal to the Average Market Price multiplied by the fractional share amount. See Section 1 of the Offer,
"The Offer".	

 
	

As described in the Offer, the maximum amount of cash consideration available pursuant to the Offer is Cdn.$9,091,281,360 and the maximum number of Teck Subordinate Voting Shares issuable pursuant to the Offer is 132,303,608 Teck Subordinate Voting
Shares. The consideration payable pursuant to the Offer will be pro rated as necessary on each Take-Up Date to ensure that the total aggregate consideration payable pursuant to the Offer and in any Compulsory Acquisition or Subsequent Acquisition
Transaction does not exceed these maximum aggregate amounts and will be based on the number of Inco Shares acquired on a Take-Up Date in proportion to the number of Inco Shares outstanding on a fully-diluted basis, as set forth in Section 1 of
the Offer, "The Offer".	

 
	
If a Shareholder delivers a Notice of Guaranteed Delivery in respect of Inco Shares deposited with this Letter of Transmittal, the election (or deemed election) made in that Notice of Guaranteed
Delivery as to the consideration to be received shall supersede any election made in this Letter of Transmittal. See Instruction 2 of this Letter of Transmittal "Procedure for Guaranteed Delivery".

	BOX 3

CURRENCY OF PAYMENT
	
 o	
Check here if you wish to receive payment of all cash consideration payable to you pursuant to the Offer in U.S. dollars based upon the Bank of Canada noon buying rate of exchange for U.S. dollars on the
applicable Take-Up Date.
	
  A Shareholder who does not check the box above will receive payment of all cash consideration pursuant to the Offer in Canadian dollars.
	

	 

	

	BOX 4

TAX DEFERRAL ELECTION FOR CANADIAN SHAREHOLDERS
	
 o	

Check this box if the beneficial owner of the deposited Inco Shares represented by the certificates listed in Box 1, (1) is an "Eligible Holder" (defined below), and (2) would like to make
the joint tax election with the Offeror described in Section 18 of the Circular, "Certain Canadian Federal Income Tax Considerations — Holders Resident in Canada — Resident Holders Who Accept the
Offer — Exchange of Inco Shares for Cash and Teck Subordinate Voting Shares — Disposition Where an Election is Made under Subsection 85(1) or 85(2) of the Tax Act" in the event that Teck Subordinate Voting
Shares are received as partial consideration for such Inco Shares. Eligible Holders who check this box and submit this Letter of Transmittal will receive a tax instruction letter from the Depositary.
	
  The joint tax election can only be made by beneficial owners of Inco Shares who are Eligible Holders, and who receive Teck Subordinate Voting Shares as part of the consideration for their Inco Shares. No
joint tax election will be made with any other persons.
	
  An "Eligible Holder" means a person who is (i) resident in Canada for purposes of the Income Tax Act
(Canada) (the "Tax Act") and who is not exempt from tax under Part I of the Tax Act, or (ii) a partnership if one or more of the partners would be an Eligible Holder.
	
  Eligible Holders should note that because of the pro ration provisions of the Offer, a Shareholder electing the Cash Alternative may receive Teck Subordinate Voting Shares, and a Shareholder electing the
Share Alternative may receive more cash than the Cdn.$0.05 per Inco Share provided for under the Share Alternative. Eligible Holders should consult their own advisors as to whether they should make this tax election and (if so) the procedure for
doing so. It is the Eligible Holder's responsibility to take the steps required to make a valid tax election.
	
 o	

Eligible Holders who check the box above and would like to make a similar election for Québec income tax purposes should also check this box to receive a tax instruction letter relating to such Québec tax election from
the Depositary.

        The
person signing this Letter of Transmittal (or, in the case of Inco Shares deposited by book-entry transfer with DTC, an Agent's Message) (the
"signatory") acknowledges receipt of the Offer and Circular and acknowledges that there will be a binding agreement between the signatory and the
Offeror effective immediately following the Offeror taking up the Inco Shares covered by this Letter of Transmittal and delivered to the Depositary or the U.S. Forwarding Agent (the
"Deposited Shares") in accordance with the terms and subject to the conditions of the Offer. The signatory represents and warrants that: (i) the
signatory has full power and authority to deposit, sell, assign and transfer all right, title and interest in and to the Deposited Shares and in and to all rights and benefits arising from such
Deposited Shares, including, without limitation, any and all dividends (other than regular quarterly cash dividends declared by Inco in accordance with its current dividend policy as established on
April 19, 2005 and amended on February 7, 2006), distributions, payments, securities, rights (including Rights), warrants, assets, property or other interests which may be declared,
paid, accrued, issued, distributed, made or transferred on or in respect of the Deposited Shares or any of them on or after the date of the Offer, including any dividends, distributions or payments on
such dividends, distributions, payments, securities, rights, (including Rights), warrants, assets, property or other interests (collectively,
"Distributions") being deposited to the Offer; (ii) the signatory or the person on whose behalf the Deposited Shares are being deposited owns
(including, without limitation, within the meaning of Rule 14e-4 under the U.S. Exchange Act) the Deposited Shares that are being deposited; (iii) the Deposited
Shares and Distributions have not been sold, assigned or transferred, nor has any agreement been entered into to sell, assign or transfer any of the Deposited Shares and Distributions, to any other
person; (iv) the deposit of the Deposited Shares and Distributions complies with applicable Laws; and (v) when the Deposited Shares and Distributions are taken up and paid for by the
Offeror, the Offeror will acquire good title thereof, free and clear of all liens, restrictions, charges, encumbrances, claims and rights of others. 

        IN CONSIDERATION OF THE OFFER AND FOR VALUE RECEIVED, upon the terms and subject to the conditions set forth in the Offer and in this
Letter of Transmittal, subject only to the withdrawal rights set out in the Offer, the signatory irrevocably accepts the Offer for and in respect of the Deposited Shares and (unless deposit is to be
made pursuant to the procedure for deposit by book-entry transfer set forth in Section 5 of the Offer, "Manner of Acceptance — Acceptance by
Book-Entry Transfer") delivers to the Offeror the enclosed Common Share certificate(s) and Rights certificate(s) (if applicable) representing the Deposited Shares and, on and
subject to the terms and conditions of the Offer, deposits, sells, assigns and transfers to the Offeror all right, title and interest in and to the Deposited Shares, and in and to all rights and
benefits arising from the Deposited Shares including any and all Distributions. 

        If,
on or after the date of the Offer, Inco should divide, combine, reclassify, consolidate, convert or otherwise change any of the Inco Shares or its capitalization, or should disclose
that it has taken or intends to take any such action, then the Offeror may, in its sole discretion and without prejudice to its rights under Section 2 of the Offer, "Conditions of the Offer",
make such adjustments as it deems appropriate to reflect such division, combination, reclassification, consolidation, conversion or other change in the Offered Consideration or other terms of the
Offer (including, without limitation, the type of securities offered to be purchased and the consideration payable therefor). 

        Inco
Shares acquired pursuant to the Offer shall be transferred by the Shareholder and acquired by the Offeror free and clear of all liens, charges, encumbrances, claims and equities and
together with all rights and benefits arising therefrom, including, without limitation, Rights, whether or not separated from the Common Shares and the right to any Distributions which may be
declared, accrued, paid, issued, distributed, made or transferred on or after date of Offer on or in respect of the Deposited Shares, whether or not separated from the Deposited Shares but subject to
any Deposited Shares being validly withdrawn by or on behalf of the depositing Shareholder. If, on or after the date of the Offer, Inco should declare or pay any dividend (other than regular quarterly
cash dividends declared by Inco in accordance with its current dividend policy as established on April 19, 2005 and amended on February 7, 2006) or declare, make or pay any other
distribution or payment on or declare, allot, reserve or issue any securities, rights or other interests with respect to any Inco Shares, which is or are payable or distributable to the Shareholders
of record on a date prior to the transfer into the name of the Offeror or its nominees or transferees on the securities register maintained by or on behalf of Inco in respect of Inco Shares, then
(a) in the case of any such cash dividend, distribution or payment that does not exceed the cash consideration per Inco Share, the cash consideration payable per Inco Share pursuant to the
Offer will be 

6

 

reduced
by the amount of any such dividend, distribution or payment; and (b) in the case of any such cash dividend, distribution or payment that exceeds the cash consideration per Inco Share,
or in the case of any other dividend, distribution, payment, right or other interest, the whole of any such dividend, distribution, payment, right or other interest will be promptly remitted and
transferred by the depositing Shareholder to the Depositary for the account of the Offeror accompanied by appropriate documentation of transfer. Pending such remittance, the Offeror will be entitled
to any such dividend, distribution, payment, right or other interest and may withhold the entire amount of cash and share consideration payable by the Offeror pursuant to the Offer or deduct from the
purchase price payable by the Offeror pursuant to the Offer the amount or value thereof, as determined by the Offeror in its sole discretion. 

        If
the Separation Time does not occur prior to the Expiry Time, a deposit of Common Shares will also constitute a deposit of the Rights associated with such Common Shares. If the
Separation Time occurs before the Expiry Time and Rights certificates are distributed by Inco to Shareholders prior to the time that the undersigned's Common Shares are deposited pursuant to the
Offer, in order for the Common Shares to be validly deposited, Rights certificate(s) representing Rights equal in number to the number of Common Shares deposited must be delivered to the Depositary or
the U.S. Forwarding Agent, as applicable. If the Separation Time occurs before the Expiry Time and Rights certificates are not distributed by the time that the undersigned deposits its Common
Shares pursuant to the Offer, the undersigned may deposit its Rights before receiving Rights certificate(s) by using the guaranteed delivery procedure set forth in the Offer and Notice of
Guaranteed Delivery. 

        In
any case, a deposit of Common Shares constitutes an agreement by the undersigned to deliver Rights certificate(s) representing Rights equal in number to the number of Common Shares
deposited pursuant to the Offer to the Depositary or the U.S. Forwarding Agent, as applicable, on or before the third trading day on the TSX after the date, if any, that Rights certificate(s)
are distributed. The Offeror reserves the right to require, if the Separation Time occurs before the Expiry Time, that the Depositary or the U.S. Forwarding Agent receives, prior to taking up
the Common Shares for payment pursuant to the Offer, Rights certificate(s) from the undersigned representing Rights equal in number to the Common Shares deposited by the undersigned. 

        If
the undersigned's Common Share certificates or Rights certificates, if applicable, are not immediately available or the undersigned cannot deliver its Common Share certificates or
Rights certificates, if applicable, and all other required documents to the Depositary or the U.S. Forwarding Agent, as applicable at or prior to the Expiry Time, the undersigned may
nevertheless validly deposit such Inco Shares according to the guaranteed delivery procedures set forth in the Offer and the Notice of Guaranteed Delivery. 

        The
execution of this Letter of Transmittal (or, in the case of Inco Shares deposited by book-entry transfer with DTC, an Agent's Message), irrevocably constitutes and
appoints, effective on and after the date that the Offeror takes up and pays for the Deposited Shares covered by this Letter of Transmittal or book entry transfer (which shares upon being taken up and
paid for are, together with any Distributions thereon, referred to as the "Purchased Securities"), any one of the President and Chief Executive Officer,
the Senior Vice President, Commercial Affairs, the Vice President and General Counsel or the Corporate Secretary of the Offeror and any other person designated by the Offeror in writing (each an
"Appointee") as the true and lawful agents, attorneys and attorneys-in-fact and proxies, with full power of substitution (such
power of attorney being deemed to be an irrevocable power coupled with an interest), of the depositing Shareholder with respect to the Purchased Securities. This Letter of Transmittal (or, in the case
of Shares deposited by book-entry transfer with DTC, an Agent's Message), authorizes an Appointee, in the name and on behalf of such Shareholder (a) to register or record the
transfer and/or cancellation of such Purchased Securities (to the extent consisting of securities) on the appropriate register maintained by or on behalf of Inco; (b) for so long as any
Purchased Securities are registered or recorded in the name of such Shareholder, to exercise any and all rights of such Shareholder including, without limitation, the right to vote, to execute and
deliver any and all instruments of proxy, authorizations or consents in form and on terms satisfactory to the Offeror in respect of any or all Purchased Securities, to revoke any such instrument,
authorization or consent, and to designate in such instrument, authorization or consent any person or persons as the proxy of such Shareholder in respect of the Purchased Securities for all purposes,
including, without limitation, in connection with any meeting or meetings (whether annual, special or otherwise or any adjournment thereof, including without limitation, any meeting to consider a
Subsequent Acquisition Transaction) of holders of relevant securities of Inco; (c) to execute, endorse and 

7

 

negotiate,
for and in the name of and on behalf of such Shareholder, any and all cheques or other instruments representing any Distribution payable to or to the order of, or endorsed in favour of,
such Shareholder; and (d) to exercise any other right of a holder of Purchased Securities. 

        A
Shareholder accepting the Offer under the terms of this Letter of Transmittal revokes any and all other authority, whether as agent, attorney-in-fact, attorney,
proxy or otherwise, previously conferred or agreed to be conferred by the Shareholder at any time with respect to the Deposited Shares or any Distributions. The Shareholder accepting the Offer agrees
that no subsequent authority, whether as agent, attorney-in-fact, attorney, proxy or otherwise will be granted with respect to the Deposited Shares or any Distributions by or
on behalf of the depositing Shareholder unless the Deposited Shares are not taken up and paid for pursuant to the Offer. A Shareholder accepting the Offer also agrees not to vote any of the Purchased
Securities at any meeting (whether annual, special or otherwise or any adjournment thereof, including, without limitation, any meeting to consider a Subsequent Acquisition Transaction) of holders of
relevant securities of Inco and not to exercise any of the other rights or privileges attached to the Purchased Securities, and agrees to execute and deliver to the Offeror any and all instruments of
proxy, authorizations or consents in form and on terms satisfactory to the Offeror in respect of any or all of the Purchased Securities, and agrees to appoint in any such instruments of proxy,
authorizations or consents, the person or persons specified by the Offeror as the proxy of the holder of the Purchased Securities. Upon such appointment, all prior proxies and
other authorizations (including, without
limitation, all appointments of any agent, attorney-in-fact or attorney) or consents given by the holder of such Purchased Securities with respect thereto will be revoked and
no subsequent proxies or other authorizations or consents may be given by such person with respect thereto.

        A
Shareholder accepting the Offer covenants under the terms of this Letter of Transmittal to execute, upon request of the Offeror, any additional documents, transfers and other
assurances as may be necessary or desirable to complete the sale, assignment and transfer of the Purchased Securities to the Offeror. Each authority herein conferred or agreed to be conferred may be
exercised during any subsequent legal incapacity of such holder and shall, to the extent permitted by law, survive the death or incapacity, bankruptcy or insolvency of the holder and all obligations
of the holder herein shall be binding upon the heirs, executors, administrators, attorneys, personal representatives, successors and assigns of such holder. 

        Settlement
with each Shareholder who has deposited and not validly withdrawn Inco Shares pursuant to the Offer will be made by the Depositary forwarding a certificate for the Teck
Subordinate Voting Shares, if any, to which such Shareholder is entitled pursuant to the Offer, and a cheque in Canadian dollars (or U.S. dollars if the Shareholder has so elected) in
payment of the cash component, if any, of the Offered Consideration and, if applicable, in payment for the cash equivalent of any fractional Teck Subordinate Voting Share determined in accordance with
the Offer, that is payable to such Shareholder. Subject to the foregoing and unless otherwise directed in this Letter of Transmittal, the certificates, if any, and cheque will be issued in the name of
the registered Shareholder of the Inco Shares so deposited. Unless the Person depositing the Inco Shares instructs the Depositary to hold the certificate representing the Teck Subordinate Voting
Shares, if any, and cheque for pick-up by checking the appropriate box in this Letter of Transmittal, the certificate, if any, and cheque will be forwarded by first class insured mail to
such Person at the address specified in this Letter of Transmittal. If no such address is specified, the certificate and cheque will be sent to the address of the Shareholder as shown on the
securities register maintained by or on behalf of Inco. Certificates and cheques mailed in accordance with this paragraph will be deemed to be delivered at the time of mailing. 

        The
undersigned understands and acknowledges that payment for Inco Shares tendered pursuant to this Letter of Transmittal will be made only after timely receipt by the Depositary of
(i) such Inco Shares, and (ii) this Letter of Transmittal or a facsimile thereof, properly completed and duly executed, with any signatures guaranteed, if so required, and all other
documents required by this Letter of Transmittal before 5:00 p.m. (Toronto time) on the third trading day on the TSX after the date on which the Expiry Time occurs. The undersigned also
understands and acknowledges that under no circumstances will interest accrue or be paid by the Offeror or the Depositary to persons depositing Inco Shares on the purchase price of Inco Shares
purchased by the Offeror, regardless of any delay in making payment of such purchase price. 

        If
any deposited Inco Shares are not accepted for payment pursuant to the terms and conditions of the Offer for any reason, or if certificates are submitted for more Inco Shares than are
deposited, certificates for 

8

 

unpurchased
Inco Shares will be returned to the depositing Shareholder as soon as is practicable following the termination or withdrawal of the Offer by either (i) sending new certificates
representing Inco Shares not purchased or by returning the deposited certificates (and other relevant documents) or (ii) in the case of Inco Shares deposited by book-entry
transfer of such Inco Shares pursuant to the procedures set forth in "Manner of Acceptance — Acceptance of Book-Entry Transfer" in Section 5 of
the Offer, such Inco Shares will be credited to the depositing holder's account maintained with the CDS or DTC, as applicable. Unless otherwise directed in this Letter of Transmittal, certificates and
other relevant documents will be forwarded by first class mail in the name of and to the address specified in this Letter of Transmittal or, if such name or address is not so specified, in such name
and to such address of the registered holder as shown on the securities register maintained by Inco or its transfer agent, as soon as practicable after the termination of the Offer. Shareholders
depositing Inco Shares will not be required to pay any fees or commissions if they accept the Offer by transmitting their Inco Shares directly to 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. 

        By
reason of the use by the signatory of an English language form of Letter of Transmittal, the signatory shall be deemed to have required that any contract evidenced by the Offer as
accepted through this Letter of Transmittal, as well as all documents related thereto, be drawn exclusively in the English language. En raison de l'usage d'une lettre d'envoi en langue anglaise par le
signataire, le soussigné et les destinataires sont présumés avoir requis que tout contrat attesté par l'offre acceptée par
cette lettre d'envoi, de même que tous les documents qui s'y rapportent, soient rédigés exclusivement en langue anglaise.

INSTRUCTIONS    
    

1.     Use of Letter of Transmittal  

	(a)
	This
Letter of Transmittal or a facsimile thereof, properly completed and duly executed, covering the Inco Shares deposited pursuant to the Offer, in either case with the signature(s)
guaranteed if required in Instruction 4 below, together with accompanying certificates representing the Deposited Shares (or, alternatively, a book-entry confirmation together with
DTC, an Agent's Message with respect thereto) and all other documents required by the terms of the Offer and this Letter of Transmittal must be received by the Depositary or the U.S. Forwarding
Agent at any of the offices specified on the back cover page at or prior to midnight (Toronto time), on August 16, 2006, unless the Offer in respect of the Inco Shares is accelerated, extended
or withdrawn or unless the procedure for guaranteed delivery set out in Instruction 2 below is used. Shareholders accepting the Offer using book-entry transfer must ensure that the
required documents are sent to the Depositary at its offices in Toronto, Ontario. Such documents should not be sent to the U.S. Forwarding Agent.

	(b)
	The
method used to deliver this Letter of Transmittal and any accompanying certificates representing Inco Shares or an Agent's Message, including delivery through DTC, is at the
option and risk of the depositing Shareholder. If certificates for Inco Shares are to be sent by mail, registered mail with return receipt requested, properly insured, is recommended, and it is
suggested that the mailing be made sufficiently in advance of the Expiry Time to permit delivery to the Depositary or the U.S. Forwarding Agent at or prior to such time. Delivery will only be
effective upon actual receipt of certificates for such Inco Shares by the Depositary.

	(c)
	Shareholders
whose Inco Shares are registered in the name of a broker, dealer, commercial bank, trust company or other nominee should immediately contact such nominee in order to take
the necessary steps to be able to deposit such Inco Shares. 

2.     Procedure for Guaranteed Delivery  

        If a Shareholder wishes to accept the Offer and either (i) the certificates representing such Shareholder's Inco Shares are not immediately available or
(ii) the holder cannot deliver the certificates and all other required documents to the Depositary or the U.S. Forwarding Agent by the Expiry Time, those Inco Shares may nevertheless be
deposited pursuant to the Offer provided that all of the following conditions are met: 

	(a)
	such
deposit is made only at the principal office of the Depositary in Toronto, Ontario by or through an Eligible Institution;

	(b)
	a
Notice of Guaranteed Delivery (which is printed on yellow paper) in the form accompanying the Offer and Circular or a facsimile thereof, properly completed and duly executed,
including a guarantee by an Eligible Institution in the form specified in the Notice of Guaranteed Delivery, is received by the Depositary at its principal office in Toronto, Ontario as set out in the
Notice of Guaranteed Delivery, at or before the Expiry Time;

	(c)
	the
certificate(s) representing all deposited Common Shares in proper form for transfer and, if the Separation Time has occurred before the Expiry Time and Rights certificates have
been distributed to Shareholders before the Expiry Time, the certificates representing the deposited Rights, together with this Letter of Transmittal or a facsimile hereof, relating to such Inco
Shares, properly completed and duly executed, with any required signature guarantees relating to such Inco Shares, and all other documents required by this Letter of Transmittal, are received by the
Depositary at its office in Toronto, Ontario at the applicable address specified in the Notice of Guaranteed Delivery before 5:00 p.m. (Toronto time) on the third trading day on the TSX after
the Expiry Date; and

	(d)
	in
the case of Rights where the Separation Time has occurred prior to the Expiry Time but Rights certificates have not been distributed to Shareholders prior to the Expiry Time, the
certificate(s) representing the deposited Rights, in proper form for transfer together with this Letter of Transmittal (or a facsimile hereof), properly completed and duly executed with
signatures guaranteed if so required, covering the deposited Rights, and all other documents required by this Letter of Transmittal 

15

 

are
received by the Depositary at its office in Toronto, Ontario at or prior to 5:00 p.m. (Toronto time) on the third trading day on the TSX after Rights are distributed to Shareholders. 

        The
Notice of Guaranteed Delivery may be delivered by hand or transmitted by facsimile or mail to the Depositary at its office in Toronto, Ontario at the applicable address set out in
the Notice of Guaranteed Delivery and must include a guarantee by an Eligible Institution in the form set out in the Notice of Guaranteed Delivery. Delivery of the Notice of
Guaranteed Delivery and this Letter of Transmittal and accompanying certificates to any office other than such office of the Depositary does not constitute delivery for purposes of satisfying a
guaranteed delivery.

        An
"Eligible Institution" means a Canadian Schedule I chartered bank, a major trust company in Canada, a member of the Securities
Transfer Agents Medallion Program (STAMP), a member of the Stock Exchange Medallion Program (SEMP), or a member of the New York Stock Exchange, Inc. Medallion Signature Program (MSP).
Members of these programs are usually members of a recognized stock exchange in Canada or the United States, members of the Investment Dealers Association of Canada, members of the National
Association of Securities Dealers, Inc. or banks or trust companies in the United States. 

3.     Signatures  

        No signature guarantee is required on this Letter of Transmittal if: 

	(a)
	this
Letter of Transmittal is signed by the registered owner of the Inco Shares exactly as the name of the registered holder appears on the Inco Share certificate deposited herewith,
and the cash payable and/or the certificates for Teck Subordinate Voting Shares issuable, in each case pursuant to the Offer, are to be delivered directly to such registered holder, or

	(b)
	Inco
Shares are deposited for the account of an Eligible Institution. 

        In
all other cases, all signatures on this Letter of Transmittal must be guaranteed by an Eligible Institution. If a certificate representing Inco Shares is registered in the name of a
person other than the signatory of this Letter of Transmittal or if the cash payable and/or certificates for the Teck Subordinate Voting Shares issuable are to be delivered to a person other than the
registered owner, the certificate must be endorsed or accompanied by an appropriate power of attorney, in either case, signed exactly as the name of the registered owner appears on the certificate
with the signature on the certificate or power of attorney guaranteed by an Eligible Institution. 

4.     Guarantee of Signatures  

        If this Letter of Transmittal is signed by a person other than the registered owner(s) of the Deposited Shares, or if Deposited Shares not purchased are to be
returned to a person other than such registered owner(s) or sent to an address other than the address of the registered owner(s) as shown on the registers of Inco or if payment is to be issued in the
name of a person other than the registered owner(s) of the Deposited Shares, such signature must be guaranteed by an Eligible Institution (except that no guarantee is required if the signature is that
of an Eligible Institution). 

5.     Fiduciaries, Representatives and Authorizations  

        Where this Letter of Transmittal is executed by a person acting as an executor, administrator, trustee or guardian, or on behalf of a corporation, partnership or
association or is executed by any other person acting in a representative or fiduciary capacity, such person should so indicate when signing and this Letter of Transmittal must be accompanied by
satisfactory evidence of the authority to act. Either of the Offeror or the Depositary, in their sole discretion, may require additional evidence of authority or additional documentation. 

6.     Delivery Instructions  

        If any cheque(s) or certificate(s) are to be sent to someone at an address other than the address of the Shareholder as it appears in Box A on this Letter
of Transmittal, entitled "Registration and Payment Instructions", then Box B on this Letter of Transmittal, entitled "Delivery Instructions", should be completed. If Box B is not
completed, any cheque(s) or certificate(s) in respect of Teck Subordinate Voting Shares issued in 

16

 

exchange
for Inco Shares will be mailed to the depositing Shareholder at the address of the Shareholder as it appears in Box A or, if no address of the Shareholder is provided in Box A,
then it will be mailed to the address of the Shareholder as it appears on the securities register of Inco. Any cheque(s) or certificate(s) mailed in accordance with the Offer and this Letter of
Transmittal will be deemed to be delivered at the time of mailing. 

7.     Partial Deposits  

        If less than the total number of Inco Shares evidenced by any certificate submitted is to be deposited, fill in the number of Inco Shares to be deposited in
Box 1 on this Letter of Transmittal. In such case, new certificate(s) for the number of Inco Shares not deposited will be sent to the registered holder as soon as practicable after the Expiry
Time (unless otherwise provided in Box B on this Letter of Transmittal). The total number of Inco Shares evidenced by all certificates delivered will be deemed to have been deposited unless
otherwise indicated. 

8.     Solicitation  

        Identify the investment dealer or broker, if any, who solicited acceptance of the Offer by completing Box F on this Letter of Transmittal and present a
list of beneficial holders, if applicable. 

9.     U.S. Shareholders and Substitute Form W-9  

        United States federal income tax law generally requires that a U.S. Shareholder who receives cash in exchange for Inco Shares must provide the
Depositary with his correct Taxpayer Identification Number ("TIN"), which, in the case of a Shareholder who is an individual, is generally the individual's social security number. If the Depositary is
not provided with the correct TIN or an adequate basis for an exemption, such holder may be subject to penalties imposed by the Internal Revenue Service and backup withholding in an amount equal to
28% of the gross proceeds of any payment received hereunder. If withholding results in an overpayment of taxes, a refund may be obtained. 

        To
prevent backup withholding, each U.S. Shareholder must provide his correct TIN by completing the "Substitute Form W-9" set forth in this document, which
requires such holder to certify under penalties of perjury, (1) that the TIN provided is correct (or that such holder is awaiting a TIN), (2) that (i) the holder is exempt
from backup withholding, (ii) the holder has not been notified by the Internal Revenue Service that he is subject to backup withholding as a result of a failure to report all interest or
dividends or (iii) the Internal Revenue Service has notified the holder that he is no longer subject to backup withholding, and (3) that the holder is a U.S. person (including a
U.S. resident alien). 

        Exempt
holders (including, among others, all corporations) are not subject to backup withholding and reporting requirements. To prevent possible erroneous backup withholding, an exempt
holder must enter its correct TIN in Part 1 of Substitute Form W-9, write "Exempt" in Part 2 of such form, and sign and date the form. See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 (the "W-9 Guidelines") for additional instructions. 

        If
Inco Shares are held in more than one name or are not in the name of the actual owner, consult the enclosed W-9 Guidelines for information on which TIN
to report. 

        If
a U.S. Shareholder does not have a TIN, such holder should: (i) consult the enclosed W-9 Guidelines for instructions on applying for a TIN,
(ii) write "Applied For" in the space for the TIN in Part 1 of the Substitute Form W-9, and (iii) sign and date the Substitute Form W-9
and the Certificate of Awaiting Taxpayer Identification Number set forth in this document. In such case, the Depositary may withhold 28% of the gross proceeds of any payment made to such holder
prior to the time a properly certified TIN is provided to the Depositary, and if the Depositary is not provided with a TIN within sixty (60) days, such amounts will be paid over to the Internal
Revenue Service. 

        If
the Substitute Form W-9 is not applicable to a U.S. Shareholder because such holder is not a U.S. person for United States federal
income tax purposes, such holder will instead need to submit an appropriate and properly completed IRS Form W-8 Certificate of Foreign Status, signed under penalty of
perjury. Such appropriate IRS Form W-8 may be obtained from the Depositary. 

17

 

        A U.S. SHAREHOLDER WHO FAILS TO PROPERLY COMPLETE THE SUBSTITUTE FORM W-9 SET FORTH IN THIS LETTER OF TRANSMITTAL OR, IF APPLICABLE, THE
APPROPRIATE IRS FORM W-8 MAY BE SUBJECT TO BACKUP WITHHOLDING OF 28% OF THE GROSS PROCEEDS OF ANY PAYMENTS MADE TO SUCH HOLDER PURSUANT TO
THE OFFER.

10.   Currency of Payment  

        Shareholders can also elect to receive all cash consideration payable to such Shareholder pursuant to the Offer in U.S. dollars. If a Shareholder wishes to
receive the cash consideration pursuant to the Offer in U.S. dollars, Box 3 above, captioned "Currency of Payment" and, if applicable, the Notice of Guaranteed Delivery must be
completed. Otherwise, cash payment will be received in Canadian dollars. The Depositary will determine the amount payable to Shareholders receiving payment in U.S. dollars based upon the Bank
of Canada noon buying rate of exchange for U.S. dollars on the applicable Take-Up Date. 

11.   Miscellaneous  

	(a)
	If
the space on this Letter of Transmittal is insufficient to list all certificates for Common Shares or Rights, if applicable, additional certificate numbers and number of Deposited
Shares may be included on a separate signed list affixed to this Letter of Transmittal.

	(b)
	If
Deposited Shares are registered in different forms (e.g., "John Doe" and "J. Doe"), a separate Letter of Transmittal should be signed for each different registration.

	(c)
	No
alternative, conditional or contingent deposits will be acceptable. All depositing holders of Inco Shares by execution of this Letter of Transmittal or a facsimile hereof waive any
right to receive any notice of the acceptance of Deposited Shares for payment, except as required by applicable law.

	(d)
	The
Offer and any agreement resulting from the acceptance of the Offer will be construed in accordance with and governed by the laws of the Province of Ontario and the federal laws of
Canada applicable therein. Each party to any agreement resulting from the acceptance of the Offer unconditionally and irrevocably attorns to the exclusive jurisdiction of the courts of the Province
of Ontario.

	(e)
	The
Offeror will not pay any fees or commissions to any broker or dealer or any other person for soliciting deposits of Inco Shares pursuant to the Offer (other than to members of the
Soliciting Dealer Group and the Depositary), except as otherwise set forth in the Offer.

	(f)
	Before
completing this Letter of Transmittal, you are urged to read the accompanying Offer and Circular.

	(g)
	All
questions as to the form of documents and the validity, eligibility (including time of receipt) and acceptance for exchange of any deposit of Inco Shares will be determined by the
Offeror, in its sole discretion, which determination will be final and binding on all parties. The Offeror reserves the absolute right to reject any and all deposits of Inco Shares determined by it
not to be in proper form, or the acceptance for exchange of Teck Subordinate Voting Shares and/or payment of cash in respect of which may, in the opinion of the Offeror's counsel, be unlawful. The
Offeror may, in its sole discretion, waive any of the conditions of the Offer, in whole or in part, at any time and from time to time on or before the Expiry Time, without prejudice to any other
rights which the Offeror may have; provided, however, that the Offeror may not waive the Minimum Tender Condition in order to acquire Inco Shares representing less than 50% of the Inco Shares
outstanding held by Independent Shareholders (as defined in the Rights Plan Agreement). No deposit of Inco Shares will be deemed to be properly made until all defects and irregularities have
been cured or waived. None of the Offeror, the Depositary or the U.S. Forwarding Agent or any other person will be under any duty to give notification of any defect or irregularity in deposits
or incur any liability for failure to give any such notice. The Offeror's interpretation of the terms and conditions of the Offer (including this Letter of Transmittal and the Notice of Guaranteed
Delivery) will be final and binding on all parties. The Offeror reserves the right to permit the Offer to be accepted in a manner other than as set forth herein.

a letter describing the loss, to the Depositary. The Depositary will forward such letter to Inco's registrar and transfer agent so that the transfer agent may provide replacement instructions. If a
certificate has been lost, destroyed, mutilated or mislaid, please ensure that you provide your telephone number so that the Depositary or Inco's transfer agent may contact you.

to the IRS. The IRS uses the number for identification purposes and may also provide this information to various government agencies for tax enforcement or litigation purposes. Payers must be given
the numbers whether or not recipients are required to file tax returns. Payers must generally withhold 28% of taxable interests, dividends, and certain other
payments made to a payee who does not furnish a taxpayer identification number to payer. Certain penalties may also apply. 

Penalties  

	(1)
	Failure to Furnish Taxpayer Identification Number. — If you fail to furnish your taxpayer
identification number to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

	(2)
	Civil Penalty for False Information With Respect to Withholding. — If you make a false statement
with no reasonable basis that results in no backup withholding, you are subject to a $500 penalty.

	(3)
	Criminal Penalty for Falsifying Information. — Willfully falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or imprisonment.

        This Notice of Guaranteed Delivery must be used to accept the offer dated May 23, 2006 (the
"Offer"), as amended and supplemented by the notice of variation and extension dated July 24, 2006 and the notice of variation and
extension dated August 3, 2006, made by Teck Cominco Limited (the "Offeror"), a corporation existing under the laws of Canada, to purchase

of Inco Limited, a corporation existing under the laws of Canada, other than any Inco Shares owned, directly or indirectly, by the Offeror and its affiliates on any Take-Up Date, if
certificates for the Inco Shares to be deposited are not immediately available or if the holder of Inco Shares (the "Shareholder") is not able to
deliver the certificates and all other required documents to the Depositary or the U.S. Forwarding Agent at or prior to the Expiry Time (as defined in the Offer). This Notice of
Guaranteed Delivery may be delivered by hand or transmitted by facsimile or mail to the Depositary at its office in Toronto, Ontario at the address or facsimile number, listed in this Notice of
Guaranteed Delivery. 

        The
terms and conditions of the Offer are incorporated by reference in this Notice of Guaranteed Delivery. Capitalized terms used but not defined in this Notice of Guaranteed
Delivery which are defined in the Offer (the "Offer") and accompanying Circular (together, the "Offer and
Circular") dated May 23, 2006, as amended and supplemented, have the meanings ascribed to them in the Offer and Circular. 

WHEN AND HOW TO USE THIS NOTICE OF GUARANTEED DELIVERY  

        As set forth in Section 5 of the Offer, "Manner of Acceptance — Procedure for Guaranteed Delivery", if a
Shareholder wishes to deposit Inco Shares pursuant to the Offer and certificates representing such Inco Shares are not immediately available or the Shareholder cannot deliver the certificates
and all other required documents to the Depositary or the U.S. Forwarding Agent by the Expiry Time, those Inco Shares may nevertheless be deposited pursuant to the Offer by utilizing the
procedures contemplated by this Notice of Guaranteed Delivery, provided that all of the following conditions are met: 

	(a)
	the
deposit is made only at the principal office of the Depositary in Toronto, Ontario or by or through an Eligible Institution;

	(b)
	this
Notice of Guaranteed Delivery or a manually signed facsimile hereof, properly completed and duly executed, including a guarantee to deliver by an Eligible Institution in
the form specified below, is received by the Depositary at its office in Toronto, Ontario as set out below, at or before the Expiry Time;

	(c)
	the
certificate(s) representing all deposited Common Shares, and if the Separation Time under the Rights Plan has occurred before the Expiry Time and Rights certificates have
been distributed to Shareholders before the Expiry Time, the certificate(s) representing the deposited Rights, each in 

 

proper
form for transfer, together with a properly completed and duly signed Letter of Transmittal and Election Form (the "Letter of Transmittal")
or a manually signed facsimile thereof, relating to such Inco Shares, with signatures guaranteed if so required in accordance with the Letter of Transmittal, and all other documents required by
the Letter of Transmittal, are received by the Depositary at its office in Toronto, Ontario at the address specified below before 5:00 p.m. (Toronto time) on the third trading day on the
Toronto Stock Exchange (the "TSX") after the date on which the Expiry Time occurs; and 

	(d)
	in
the case of Rights where the Separation Time has occurred prior to the Expiry Time but Rights certificates have not been distributed to Shareholders prior to the Expiry Time,
the certificate(s) representing the deposited Rights, in proper form for transfer together with the Letter of Transmittal (or a facsimile thereof), properly completed and duly executed,
covering the deposited Rights, and all other documents required by the Letter of Transmittal are received by the Depositary at its office in Toronto, Ontario or the U.S. Forwarding Agent
before 5:00 p.m. (Toronto time) on the third trading day on the TSX after Rights certificates are distributed to Shareholders. 

        An
"Eligible Institution" means a Canadian Schedule I chartered bank, a major trust company in Canada, a member of the
Securities Transfer Agents Medallion Program (STAMP), a member of the Stock Exchange Medallion Program (SEMP), or a member of the New York Stock Exchange, Inc. Medallion Signature
Program (MSP). Members of these programs are usually members of a recognized stock exchange in Canada or the United States, members of the Investment Dealers Association of Canada,
members of the National Association of Securities Dealers, Inc. or banks or trust companies in the United States. 

        The
undersigned understands and acknowledges that payment for Inco Shares tendered pursuant to the Letter of Transmittal will be made only after timely receipt by the Depositary or
the U.S. Forwarding Agent of (i) such Inco Shares, and (ii) a Letter of Transmittal or a facsimile thereof, properly completed and duly executed, with any signatures
guaranteed, if so required, and all other documents required by the Letter of Transmittal before 5:00 p.m. (Toronto time) on the third trading day on the TSX after the date on which the
Expiry Time occurs. The undersigned also understands and acknowledges that under no circumstances will interest accrue or be paid by the Offeror or the Depositary to persons depositing Inco
Shares on the purchase price of Inco Shares purchased by the Offeror, regardless of any delay in making payment of such purchase price, and that the consideration for Inco Shares tendered
pursuant to the guaranteed delivery procedures will be the same as that for Inco Shares delivered to the Depositary before the Expiry Time, even if the Inco Shares to be delivered pursuant to
the guaranteed delivery procedures are not so delivered to the Depositary, and therefore payment by the Depositary on account of such Inco Shares is not made, until after the take up and payment
for the Inco Shares pursuant to the Offer. 

        All
authority conferred, or agreed to be conferred, by this Notice of Guaranteed Delivery may be exercised during any subsequent legal incapacity of the undersigned and shall, to
the extent permitted by law, survive the death or incapacity, bankruptcy or insolvency of the undersigned and all obligations of the undersigned under this Notice of Guaranteed Delivery shall be
binding upon the heirs, personal representatives, successors and assigns of the undersigned.

from the undersigned representing Rights equal in number to the Common Shares deposited.

ELECTION FOR CASH OR SHARES	

 
	
Pursuant to the Offer, the undersigned hereby elects to receive one of the following forms of consideration for all of the deposited Inco Shares represented by the certificate(s) listed above.
Shareholders may elect to receive the Cash Alternative (Choice A) OR the Share Alternative (Choice B).	

 
	
Shareholders may choose only ONE of the choices below:	

 
	
 o  Choice A — The CASH ALTERNATIVE	

 
	
Shareholders who check this box will receive Cdn.$82.50 in cash for each Inco Share

deposited under this Choice A (subject to pro ration and subject to the election made below with respect to currency of payment)	

 
	
o  Choice B — The SHARE ALTERNATIVE	

 
	
Shareholders who check this box will receive 1.1293 Class B subordinate voting shares of

Teck Cominco Limited ("Teck Subordinate Voting Share") and Cdn.$0.05 in cash for each

Inco Share deposited under this Choice B (subject to pro ration and subject to the election made below with respect to currency of payment)	

 
	
If a Shareholder fails to elect the Cash Alternative or does not properly elect either the Cash Alternative, on the one hand, or the Share Alternative, on the other hand, with respect to any Inco
Shares deposited by the Shareholder pursuant to the Offer, such Shareholder will be deemed to have elected the Share Alternative and will be entitled to receive only 1.1293 Teck Subordinate Voting Shares and Cdn.$0.05 in cash as consideration for
each of such Shareholder's Inco Shares, subject to pro ration as described in Section 1 of the Offer, "The Offer".	

 
	
 Fractional Teck Subordinate Voting Shares will not be issued in connection with the Offer. Where on any Take-Up Date a Shareholder is to receive Teck Subordinate Voting Shares as consideration pursuant
to the Offer and the aggregate number of Teck Subordinate Voting Shares to be issued to such Shareholder would result in a fraction of a Teck Subordinate Voting Share being issuable, the number of Teck Subordinate Voting Shares to be received by such
Shareholder will be rounded down and in lieu of a fractional Teck Subordinate Voting Share, the Shareholder will receive a cash payment determined on the basis of an amount equal to the Average Market Price multiplied by the fractional share amount.
See Section 1 of the Offer, "The Offer".	

 
	
 As described in the Offer, the maximum amount of cash consideration available pursuant to the Offer is Cdn.$9,091,281,360 and the maximum number of Teck Subordinate Voting Shares issuable pursuant to
the Offer is 132,303,608 Teck Subordinate Voting Shares. The consideration payable pursuant to the Offer will be pro rated as necessary on each Take-Up Date to ensure that the total aggregate consideration payable pursuant to the Offer and in
any Compulsory Acquisition or Subsequent Acquisition Transaction does not exceed these maximum aggregate amounts and will be based on the number of Inco Shares on a Take-Up Date acquired in proportion to the number of Inco Shares outstanding on a
fully-diluted basis, as set forth in Section 1 of the Offer, "The Offer".	

 
	
An election (or deemed election) as to the consideration to be received by a Shareholder made in this Notice of Guaranteed Delivery shall supersede any election made in a Letter of
Transmittal.
