Preliminary Short Form Prospectus


NEW ISSUE		October 30, 2007

TECK COMINCO LIMITED

US$2,500,000,000
Debt Securities

Teck Cominco Limited (“Teck Cominco” or the “company”) may from time to time offer for sale debt securities up to an aggregate initial offering price of US$2,500,000,000 (or the equivalent in other currencies), during the 25 month period that this prospectus, including any amendments hereto, remains valid. The debt securities may be offered separately or together, in one or more series, in amounts, at prices and on other terms to be determined based on market conditions at the time of sale and set forth in an accompanying prospectus supplement.

We will provide the specific terms of the debt securities in respect of which this prospectus is being delivered (the “offered debt securities”) and all information omitted from this prospectus in supplements to this prospectus. You should read this prospectus and any applicable prospectus supplement carefully before you invest.

Neither the United States Securities and Exchange Commission nor any state securities regulator has approved or disapproved these debt securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

We are permitted, under a multijurisdictional disclosure system adopted by the United States and Canada, to prepare this prospectus in accordance with Canadian disclosure requirements, which are different from United States disclosure requirements. We prepare our financial statements, which are incorporated by reference herein, in accordance with Canadian generally accepted accounting principles, and they are subject to Canadian auditing and auditor independence standards. As a result, they may not be comparable to financial statements of United States companies.

Owning the debt securities may subject you to tax consequences both in the United States and Canada. This prospectus or any applicable prospectus supplement may not describe these tax consequences fully. You should read the tax discussion in any applicable prospectus supplement and should consult with your own tax advisor with respect to your own particular circumstances.

Your ability to enforce civil liabilities under the United States federal securities laws may be affected adversely because we are incorporated in Canada, most of our officers and directors and some of the experts named in this prospectus are not residents of the United States, and many of our assets and all or a substantial portion of the assets of such persons are located outside of the United States.

The company may sell the debt securities to or through underwriters or dealers, and also may sell the debt securities to one or more other purchasers directly or through agents. See “Plan of Distribution”. A prospectus supplement will set forth the names of any underwriters, dealers or agents involved in the sale of any offered debt securities and will set forth the terms of the offering of the offered debt securities, including, to the extent applicable, the initial public offering price, the proceeds to the company, the principal amounts, if any, to be purchased by underwriters, the underwriting discounts or commissions, and any other discounts or concessions to be allowed or reallowed to dealers.

Our head and registered office is located at 200 Burrard Street, Suite 600, Vancouver, British Columbia V6C 3L9.

Except as set forth under “Description of Debt Securities”, and unless the context otherwise requires, all references in this prospectus to the “company”, “we”, “us” and “our” refer to Teck Cominco Limited and its subsidiaries and joint ventures.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement on Form F-9 relating to the debt securities that we have filed with the United States Securities and Exchange Commission (the “SEC”). Under the registration statement, we may, from time to time, sell any combination of the debt securities described in this prospectus in one or more offerings up to an aggregate initial offering price of US$2,500,000,000. This prospectus provides you with a general description of the debt securities that we may offer. Each time we sell debt securities under the registration statement, we will provide a prospectus supplement that will contain specific information about the terms of that offering of debt securities. The prospectus supplement may also add, update or change information contained in this prospectus. Before you invest, you should read both this prospectus and any applicable prospectus supplement together with the additional information described under the heading “Where You Can Find More Information”. This prospectus does not contain all of the information set forth in the registration statement, certain parts of which are omitted in accordance with the rules and regulations of the SEC. You may refer to the registration statement and the exhibits to the registration statement for further information with respect to us and the debt securities.

The debt securities will not be qualified for sale under the securities laws of Canada or any province or territory of Canada, unless the applicable prospectus supplement indicates otherwise with respect to the offered debt securities, and may not be offered or sold, directly or indirectly, in Canada or to residents of Canada in contravention of the securities laws of any province or territory of Canada. Each underwriter and each dealer participating in the distribution of offered debt securities will agree that, unless the applicable prospectus supplement indicates otherwise, it will not, directly or indirectly, offer, sell or deliver any such offered debt securities purchased by it in connection with such distribution, in Canada or to residents of Canada in contravention of the securities laws of any province or territory of Canada.

WHERE YOU CAN FIND MORE INFORMATION

We file with the British Columbia Securities Commission (the “BCSC”), a commission of authority in the Province of British Columbia, Canada, similar to the SEC, and with the various securities commissions or similar authorities in each of the provinces and territories of Canada, annual and quarterly reports, material change reports and other information. We are also an SEC registrant subject to the informational requirements of the U.S. Securities Exchange Act of 1934 (the “Exchange Act”) and accordingly, file with, or furnish to, the SEC certain reports and other information. Under a multijurisdictional disclosure system adopted by the United States and Canada, these reports and other information (including financial information) may be prepared in accordance with the disclosure requirements of Canada, which differ from those in the United States. You may read and copy any document we file with or furnish to the SEC at the SEC’s public reference room at 100 F Street, N.E., Room 1580, Washington, D.C. 20549. You may also obtain copies of the same documents from the public reference room by paying a fee. Please call the SEC at 1-800-SEC-0330 or contact them at www.sec.gov for further information on the public reference room and copying charges.

Under the multijurisdictional disclosure system adopted by the United States and Canada, the SEC and the BCSC allow us to “incorporate by reference” certain information that we file with them, which means that we can disclose important information to you by referring you to those documents. Information that is incorporated by reference is an important part of this prospectus.

We caution that the foregoing list of important factors and assumptions is not exhaustive. Events or circumstances could cause our actual results to differ materially from those estimated or projected and expressed in, or implied by, these forward-looking statements. Accordingly, you should not place undue reliance on forward-looking statements. You should also carefully consider the matters discussed under “Risk Factors” in this prospectus. We undertake no obligation to update publicly or otherwise revise any forward-looking statements or the foregoing list of factors, whether as a result of new information or future events or otherwise, except as may be required in connection with a material change in the information disclosed in this prospectus or as otherwise required by law.

RISK FACTORS

Before making an investment decision, you should carefully consider the risks and uncertainties described below as well as the other information contained and incorporated by reference in this prospectus. These risks and uncertainties are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently consider immaterial may also impair our business operations. If any of such risks actually occur, our business, prospects, financial condition, cash flows and operating results could be materially harmed.

We face risks in the mining and metals business

The business of exploring for minerals is inherently risky. Few properties that are explored are ultimately developed into producing mines.

Mineral properties are often non-productive for reasons that cannot be anticipated in advance. Even after the commencement of mining operations, such operations may be subject to risks and hazards, including environmental hazards, industrial accidents, unusual or unexpected geological formations, unanticipated metallurgical difficulties, ground control problems and flooding. The Trail metallurgical operations, and our concentrate mills and coal preparation plants are also subject to risks of process upsets and equipment malfunctions. Equipment and supplies may from time to time be unavailable on a timely basis. The occurrence of any of the foregoing could result in damage to or destruction of mineral properties or production facilities, personal injuries or death, environmental damage, delays or interruption of production, increases in production costs, monetary losses, legal liability and adverse governmental action.

Our insurance may not provide adequate coverage

Our property, business interruption and liability insurance may not provide sufficient coverage for losses related to these or other hazards. Insurance against certain risks, including certain liabilities for environmental pollution, may not be available to us or to other companies within the industry. In addition, our insurance coverage may not continue to be available at economically feasible premiums, or at all. Any such event could have a material adverse affect on our business.

We could be subject to potential labour unrest or other labour disturbances as a result of the failure of negotiations in respect of our collective agreements

Over 6,400 of our approximately 8,700 employees are employed under collective bargaining agreements. We could be subject to labour unrest or other labour disturbances as a result of delays in or the failure of negotiations in respect of our collective agreements, which could, while ongoing, have a material adverse effect on our business.

We may not be able to hire enough skilled employees to support our operations

We compete with other mining companies to attract and retain key executives and skilled and experienced employees. The mining industry is labour intensive and our success depends to a significant extent on our ability to attract, hire, train and retain qualified employees, including our ability to attract employees with needed skills in the geographic areas in which we operate. We could experience increases in our recruiting and training costs and decreases in our operating efficiency, productivity and profit margins, if we are not able to attract, hire and retain a sufficient number of skilled employees to support our operations.

We could become subject to material pension liabilities

We have assets in defined benefit pension plans which arise through employer contributions and returns on investments made by the plans. The returns on investments are subject to fluctuations depending upon market conditions and we are responsible for funding any shortfall of pension assets compared to our pension obligations under these plans.

We also have certain obligations to former employees with respect to post-retirement benefits. The cost of providing these benefits can fluctuate and the fluctuations can be material.

Our liabilities under defined benefit pension plans and in respect of other post-retirement benefits are estimated based on actuarial and other assumptions. These assumptions may prove to be incorrect and may change over time and the effect of these changes can be material.

Fluctuations in the market price of base metals, specialty metals, metallurgical coal and gold may significantly affect the results of our operations

The results of our operations are significantly affected by the market price of base metals, specialty metals, metallurgical coal and gold, which are cyclical and subject to substantial price fluctuations. Our earnings are particularly sensitive to changes in the market price of zinc, copper and metallurgical coal. Market prices can be

affected by numerous factors beyond our control, including levels of supply and demand for a broad range of industrial products, substitution of new or different products in critical applications for our existing products, expectations with respect to the rate of inflation, the relative strength of the Canadian dollar and of certain other currencies, interest rates, speculative activities, global or regional political or economic crises and sales of gold and base metals by holders in response to such factors. If prices should decline below our cash costs of production and remain at such levels for any sustained period, we could determine that it is not economically feasible to continue commercial production at any or all of our mines. We may also curtail or suspend some or all of our exploration activities, with the result that our depleted reserves are not replaced.

Our general policy is not to hedge changes in prices of our mineral production. From time to time, however, we may undertake hedging programs in specific circumstances, with an intention to reduce the risk of a commodity’s market price while optimizing upside participation, to maintain adequate cash flows and profitability to contribute to the long-term viability of our business. There are, however, risks associated with hedging programs including, among other things, an increase in the world price of the commodity, an increase in gold lease rates (in the case of gold hedging), an increase in interest rates, rising operating costs, counterparty risks and production interruption events.

Fluctuations in the price and availability of consumed commodities affect our costs of production

Prices and availability of commodities consumed or used in connection with exploration, development, mining, smelting and refining, such as natural gas, diesel, oil and electricity, as well as reagents such as copper sulfate, also fluctuate and these fluctuations affect the costs of production at our various operations. Our smelting and refining operations at Trail require concentrates that we purchase from third parties. The availability of those concentrates and the treatment charges we can negotiate fluctuate depending on market conditions. These fluctuations can be unpredictable, can occur over short periods of time and may have a materially adverse impact on our operating costs or the timing and costs of various projects. Our general policy is not to hedge our exposure to changes in prices of the commodities we use in our business.

We face risks associated with shortage of mining equipment and supplies

The growth in global mining activities has created a demand for mining equipment and related supplies that exceeds supply. For example, there is a global shortage of haulage truck tires which is expected to continue into 2008. Consequently, if equipment or other supplies cannot be procured on a timely basis, our expansion activities, production, development or operations could be negatively affected. The pace of global mining development activities has also led to supply constraints, limitation on the availability of labour and other cost pressures that will affect our development operations. Lead times for major equipment orders have increased. Wage pressures and other cost escalation will also affect construction activities at our development projects.

Our acquisition of properties may be affected by competition from other mining companies

Because the life of a mine is limited by its ore reserves, we are continually seeking to replace and expand our reserves through the exploration of our existing properties as well as through acquisitions of interests in new properties or of interests in companies which own such properties. We encounter strong competition from other mining companies in connection with the acquisition of properties. This competition may increase the cost of acquiring suitable properties, should such properties become available to us.

We face competition in product markets

The mining industry in general is intensely competitive and even if commercial quantities of mineral resources are developed, a profitable market may not exist for the sale of such minerals. We must sell base metals, metal concentrates, by-product metals and concentrate, metallurgical coal and gold at prices determined by world markets over which we have no influence or control. Our competitive position is determined by our costs in comparison to those of other producers in the world. If our costs increase due to our locations, grade and nature of ore bodies, foreign exchange rates, or our operating and management skills, our profitability may be affected. We

have to compete with larger companies that have greater assets and financial and human resources than us, and which may be able to sustain larger losses than us to develop or continue business.

We may face restricted access to markets in the future

Access to our markets may be subject to ongoing interruptions and trade barriers due to policies and tariffs of individual countries, and the actions of certain interest groups to restrict the import of certain commodities. Although there are currently no significant trade barriers existing or impending of which we are aware that do, or could, materially affect our access to certain markets, there can be no assurance that our access to these markets will not be restricted in the future.

Our reserve and resource estimates may prove to be incorrect

Disclosed reserve estimates should not be interpreted as assurances of mine life or of the profitability of current or future operations. We estimate and report our mineral reserves and resources in accordance with the requirements of the applicable Canadian securities regulatory authorities and industry practice.

We estimate and report oil and gas reserves and resources in accordance with the requirements of the applicable Canadian securities regulatory authorities and industry practice. Estimates of reserves and resources for oil and gas reporting purposes are not comparable to mineral reserve and resource estimates.

The SEC does not permit mining companies in their filings with the SEC to disclose estimates other than mineral reserves. However, because we prepared this prospectus in accordance with Canadian disclosure requirements, this prospectus also incorporates estimates of mineral resources. Mineral resources are concentrations or occurrences of minerals that are judged to have reasonable prospects for economic extraction, but for which the economics of extraction cannot be assessed, whether because of insufficiency of geological information or lack of feasibility analysis, or for which economic extraction cannot be justified at the time of reporting. Consequently, mineral resources are of a higher risk and are less likely to be accurately estimated or recovered than mineral reserves.

Our mineral reserves and resources are estimated by persons who are employees of the respective operating company for each of our operations under the supervision of our employees. These individuals are not “independent” for purposes of applicable securities legislation. As a rule, we do not use outside sources to verify mineral reserves or resources except at the initial feasibility stage.

The mineral and oil and gas reserve and resource figures incorporated in this prospectus by reference are estimates based on the interpretation of limited sampling and subjective judgments regarding the grade, continuity and existence of mineralization, as well as the application of economic assumptions, including assumptions as to operating costs, foreign exchange rates and future commodity prices. The sampling, interpretations or assumptions underlying any reserve or resource estimate may be incorrect, and the impact on reserves or resources may be material. Should the mineralization and/or configuration of a deposit ultimately turn out to be significantly different from that currently envisaged, then the proposed mining plan may have to be altered in a way that could affect the tonnage and grade of the reserves mined and rates of production and, consequently, could adversely affect the profitability of the mining operations. In addition, short term operating factors relating to the reserves, such as the need for orderly development of ore bodies or the processing of new or different ores, may cause reserve and resource estimates to be modified or operations to be unprofitable in any particular fiscal period.

There can be no assurance that our projects or operations will be, or will continue to be, economically viable, that the indicated amount of minerals or petroleum products will be recovered or that they will be recovered at the prices assumed for purposes of estimating reserves.

The depletion of our mineral reserves may not be offset by future discoveries or acquisitions of mineral reserves

We must continually replace mineral reserves depleted by production to maintain production levels over the long term. This is done by expanding known mineral reserves or by locating or acquiring new mineral deposits.

There is, however, a risk that depletion of reserves will not be offset by future discoveries of mineral reserves. Exploration for minerals and oil and gas is highly speculative in nature and the projects involve many risks. Many projects are unsuccessful and there are no assurances that current or future exploration programs will be successful. Further, significant costs are incurred to establish mineral or oil and gas reserves and to construct mining and processing facilities. Development projects have no operating history upon which to base estimates of future cash flow and are subject to the successful completion of feasibility studies, obtaining necessary government permits, obtaining title or other land rights and availability of financing. In addition, assuming discovery of an economic orebody, depending on the type of mining operation involved, many years may elapse from the initial phases of drilling until commercial operations are commenced. Accordingly, there can be no assurances that our current work programs will result in any new commercial mining operations or yield new reserves to replace and/or expand current reserves.

We may be adversely affected by currency fluctuations

Our operating results and cash flow are affected by changes in the Canadian dollar exchange rate relative to the currencies of other countries. Exchange rate movements can have a significant impact on results as a significant portion of our operating costs are incurred in Canadian and other currencies and most revenues are earned in U.S. dollars. To reduce the exposure to currency fluctuations, we enter into limited foreign exchange contracts from time to time, but these hedges do not eliminate the potential that such fluctuations may have an adverse effect on us. In addition, foreign exchange contracts expose us to the risk of default by the counterparties to such contracts, which could have a material adverse effect on our business.

We may be adversely affected by interest rate changes

Our exposure to changes in interest rates results from investing and borrowing activities undertaken to manage our liquidity and capital requirements. We have incurred indebtedness that bears interest at fixed and floating rates, and we have entered into interest rate swap agreements to effectively convert some fixed rate exposure to floating rate exposure. There can be no assurance that we will not be materially adversely affected by interest rate changes in the future. In addition, our use of interest rate swaps exposes us to the risk of default by the counterparties to such arrangements. Any such default could have a material adverse effect on our business.

Changes in environmental, health and safety laws may have a material adverse effect on our operations

Environmental, health and safety legislation affects nearly all aspects of our operations, including mine development, worker safety, waste disposal, emissions controls and protection of endangered and protected species. Compliance with environmental, health and safety legislation can require significant expenditures and failure to comply with environmental, health or safety legislation may result in the imposition of fines and penalties, the temporary or permanent suspension of operations, clean-up costs arising out of contaminated properties, damages, and the loss of important permits. Exposure to these liabilities arises not only from our existing operations, but from operations that have been closed or sold to third parties. We are required to reclaim properties after mining is completed and specific requirements vary among jurisdictions. In some cases, we may be required to provide financial assurances as security for reclamation costs, which may exceed our estimates for such costs. Our historical operations have generated significant environmental contamination. We could also be held liable for worker exposure to hazardous substances. There can be no assurances that we will at all times be in compliance with all environmental, health and safety regulations or that steps to achieve compliance would not materially adversely affect our business.

Environmental, health and safety laws and regulations are evolving in all jurisdictions where we have activities. We are not able to determine the specific impact that future changes in environmental laws and regulations may have on our operations and activities, and our resulting financial position; however, we anticipate that capital expenditures and operating expenses will increase in the future as a result of the implementation of new and increasingly stringent environment, health and safety regulations. For example, emissions standards for carbon dioxide and sulphur dioxide are becoming increasingly stringent as are laws relating to the use and production of regulated chemical substances. Further changes in environmental, health and safety laws, new information on existing environmental, health and safety conditions or other events, including legal proceedings based upon such conditions, or an inability to obtain necessary permits, could require increased financial reserves or compliance

expenditures or otherwise have a material adverse effect on us. Changes in environmental, health and safety legislation could also have a material adverse effect on product demand, product quality and methods of production and distribution. In the event that any of our products were demonstrated to have negative health effects, we could be exposed to workers compensation and product liability claims which could have a material adverse effect on our business.

We are highly dependent on third parties for the provision of transportation services

Due to the geographical location of many of our mining properties and operations, we are highly dependent on third parties for the provision of rail and port services. We negotiate prices for the provision of these services in circumstances where we may not have viable alternatives to using specific providers, or have access to regulated rate setting mechanisms. Contractual disputes, demurrage charges, rail and port capacity issues, availability of vessels and rail cars, weather problems or other factors can have a material adverse effect on our ability to transport materials according to schedules and contractual commitments.

Our Red Dog mine operates year-round on a 24 hour per day basis. The annual production of the mine must be stored at the port site and shipped within an approximately 100-day window when sea ice and weather conditions permit. Two purpose-designed shallow draft barges transport the concentrates to deep water moorings. The barges cannot operate in severe swell conditions.

Unusual ice or weather conditions, or damage to the barges or ship loading equipment could restrict our ability to ship all of the stored concentrate. Failure to ship the concentrate during the shipping season could have a material adverse effect on our sales, as well as on our Trail metallurgical operations, and could materially restrict mine production subsequent to the shipping season.

Aboriginal title claims and rights to consultation and accommodation may affect our existing operations as well as development projects and future acquisitions

Governments in many jurisdictions must consult with aboriginal peoples with respect to grants of mineral rights and the issuance or amendment of project authorizations. Consultation and other rights of aboriginal people may require accommodations, including undertakings regarding employment and other matters in impact and benefit agreements. This may affect our ability to acquire within a reasonable time frame effective mineral titles in these jurisdictions, including in some parts of Canada in which aboriginal title is claimed, and may affect the timetable and costs of development of mineral properties in these jurisdictions. The risk of unforeseen aboriginal title claims also could affect existing operations as well as development projects and future acquisitions. These legal requirements may affect our ability to expand or transfer existing operations or to develop new projects.

We operate in foreign jurisdictions and face added risks and uncertainties due to different economic, cultural and political environments

Our business operates in a number of foreign countries where there are added risks and uncertainties due to the different economic, cultural and political environments. Some of these risks include nationalization and expropriation, social unrest and political instability, uncertainties in perfecting mineral titles, trade barriers and exchange controls and material changes in taxation. Further, developing country status or an unfavorable political climate may make it difficult for us to obtain financing for projects in some countries.

We face risks associated with our development projects

The Fort Hills project is at an early stage of development. Petro-Canada, as project operator, in consultation with UTS and us, will be responsible for further definition of the scope and parameters of the project and its design and development. There can be no assurance that the development or construction activities will commence in accordance with current expectations or at all. The Galore Creek project is at a similar stage of development. Construction and development of these projects are subject to numerous risks, including, without limitation:

	•		risks resulting from the fact that the Fort Hills project and the Galore Creek project are at an early stage of development and therefore are subject to development and construction risks, including the risk of significant cost overruns and delays in construction, and technical and other problems;

	•		risks associated with delays in obtaining, or conditions imposed by, regulatory approvals;

	•		risks associated with obtaining amendments to existing regulatory approvals and additional regulatory approvals which will be required;

	•		risks of significant fluctuation in prevailing prices for copper, gold, oil, other petroleum products and natural gas, which may affect the profitability of the projects;

	•		risks resulting from the fact that we are a minority partner in the Fort Hills Energy Limited Partnership and major decisions with respect to project design and construction may be made without our consent;

	•		risks associated with the fact that our company and NovaGold Canada Inc. are 50% partners in the Galore Creek project and major project decisions require the agreement of both parties;

	•		risks associated with litigation;

	•		risks resulting from dependence on third parties for services and utilities for the project;

	•		risks associated with the ability of our partners to finance their respective shares of project expenditures; and

	•		risks associated with our obtaining financing for these projects on commercially reasonable terms.

Regulatory efforts to control greenhouse gas emissions could materially negatively affect our business

Our businesses include several operations that emit large quantities of carbon dioxide, or that produce or will produce products that emit large quantities of carbon dioxide when consumed by end users. This is particularly the case with our metallurgical coal operations and our oil sands projects. Carbon dioxide and other greenhouse gases are the subject of increasing public concern and regulatory scrutiny.

The Kyoto Protocol is an international agreement that sets limits on greenhouse gas emissions from certain signatory countries. While the United States government has announced that it will not ratify the protocol, the Canadian Parliament voted to ratify its participation in this agreement and the Kyoto Protocol came into force in Canada on February 16, 2005. The Kyoto agreement commits Canada to limit its net greenhouse gas emissions to 6% below the levels emitted in 1990. Canada’s current level of greenhouse gas emissions significantly exceeds the agreed-upon limit.

In 2007, the Government of Canada announced a policy objective of reducing total Canadian greenhouse gas emissions by 20% below 2006 levels by 2020 and by 60% to 70% below that level by 2050. As part of this initiative, the federal Government intends to require reductions in emission intensity levels from certain industrial facilities, including oil and gas facilities and smelting and refining facilities, by 6% per year for each year from 2007 to 2010 and 2% per year each year thereafter. Affected facilities will be permitted to meet reduction targets by emissions trading or contributions to a technology fund, in addition to emissions abatement. Additional policy measures are anticipated in coming years under this federal policy framework.

In Alberta, the Climate Change and Emissions Management Act and the Specified Gas Emitters Regulation require certain existing large emitters (facilities, including oil sands facilities, that are releasing 100,000 tonnes or more of greenhouse gas emissions in any calendar year after and including 2003) to reduce their emissions intensity by 12% starting July 1, 2007. The regulation also outlines options for meeting reduction targets. If reducing emissions intensity by 12% is not initially possible, large emitters will be able to invest in an Alberta-based technology fund to develop infrastructure to reduce

emissions or to support research into innovative climate change solutions. Large emitters will be required to pay $15 per tonne to the technology fund for every tonne of emissions above the 12% reduction target. Alternatively, large emitters could also invest in Alberta-based projects outside their operations that reduce or offset emissions on their behalf.

In British Columbia, the provincial government has announced a policy goal of reducing greenhouse gas emission by at least 33% below current levels by 2020. Interim targets will be set for 2012 and 2016. The mechanisms by which these targets are to be achieved are not yet established.

The primary source of greenhouse gas emissions in Canada is the use of hydrocarbon energy. Our operations depend significantly on hydrocarbon energy sources to conduct daily operations, and there are currently no economic substitutes for these forms of energy. The federal and provincial governments have not finalized any formal regulatory programs to control greenhouse gases and it is not yet possible to reasonably estimate the nature, extent, timing and cost of any programs proposed or contemplated, or their potential effects on operations. Most of Elk Valley Coal Partnership’s products are sold outside of Canada, and sales are not expected to be significantly affected by Canada’s Kyoto ratification decision. However, the broad adoption by Kyoto signatory countries and others of emission limitations or other regulatory efforts to control greenhouse gas emissions could materially negatively affect the demand for coal, oil and natural gas, as well as restrict development of new coal or oil sands projects and increase production and transportation costs.

Although we believe our financial statements are prepared with reasonable safeguards to ensure reliability, we cannot provide absolute assurance

We prepare our financial reports in accordance with accounting policies and methods prescribed by Canadian generally accepted accounting principles. In the preparation of financial reports, management may need to rely upon assumptions, make estimates or use their best judgment in determining the financial condition of the company. Significant accounting policies are described in more detail in the notes to our annual consolidated financial statements for the year ended December 31, 2006, which are incorporated by reference into this prospectus. In order to have a reasonable level of assurance that financial transactions are properly authorized, assets are safeguarded against unauthorized or improper use and transactions are properly recorded and reported, we have implemented and continue to analyze our internal control systems for financial reporting. Although we believe our financial reporting and financial statements are prepared with reasonable safeguards to ensure reliability, we cannot provide absolute assurance in that regard.

We are subject to legal proceedings, the outcome of which may affect our business

The nature of our business subjects us to numerous regulatory investigations, claims, lawsuits and other proceedings in the ordinary course of our business. The results of these legal proceedings cannot be predicted with certainty. There can be no assurances that these matters will not have a material adverse effect on our business.

Prior to our acquisition in 2000 of a majority interest in Cominco Ltd. (now Teck Cominco Metals Ltd.) (“Cominco”), Cominco’s Trail smelter discharged smelter slag into the Columbia River. These discharges commenced prior to Cominco’s acquisition of the Trail smelter in 1906 and continued until 1996. Slag was discharged pursuant to permits issued in British Columbia subsequent to the enactment of relevant environmental legislation in 1967. Slag and other non-slag materials released from the Trail smelter in British Columbia have traveled down river and mixed with substances discharged from many other smelting and industrial facilities located along the length of the Upper Columbia River system in Canada and the U.S.A.

Slag is a glass-like compound consisting primarily of silica, calcium and iron, which contains small amounts of base metals such as zinc, lead, copper and cadmium. It is sufficiently inert that it is not characterized as a hazardous waste under applicable Canadian or U.S. regulations. While slag has been deposited into the river, further study is required to assess what effect the presence of slag in the river has had and whether it poses an unacceptable risk to human health or the environment. A large number of studies regarding slag deposition and its effects have been conducted by various governmental agencies on both sides of the border. The historical studies of which we are aware have not identified unacceptable risks resulting from the presence of slag in the river.

On June 2, 2006, Cominco and our affiliate, Teck Cominco American Incorporated (“TCAI”), entered into a Settlement Agreement (the “Agreement”) with the U.S. Environmental Protection Agency (“EPA”) and the United States under which TCAI is paying for and conducting a remedial investigation and feasibility study (“RI/FS”) of contamination in the Upper Columbia River (the “Studies”) under the oversight of the EPA. The RI/FS is being prepared by independent consultants approved by the EPA and retained by TCAI. TCAI is paying the EPA’s oversight costs and providing funding for the participation of other governmental parties, the State of Washington and two native tribes, the Confederated Tribes of the Colville Nation (the “Colville Tribe”) and the Spokane Tribe. Cominco has guaranteed TCAI’s performance of the Agreement. TCAI has also placed US$20 million in escrow as financial assurance of its obligations under the Agreement and we have accrued our estimate of the costs of the Studies. Contemporaneously with the execution of the Agreement, the EPA withdrew a unilateral administrative order (“UAO”) purporting to compel Cominco to conduct the Studies.

The RI/FS process requires TCAI to submit a work plan for the assessment of site conditions to the EPA which, when approved, will lead to the development of a set of sampling and other plans and actual field work. Data from field work will be used to determine whether further studies are required. When sufficient data have been compiled to adequately assess risk, a baseline human health and environmental risk assessment (“RA”) will be produced to identify risks, if any, that may exist to humans and to various environmental receptors. The RA will form the basis for the RI/FS. The remedial investigation will identify potential remedial options available to mitigate any unacceptable risks; the feasibility study will consider engineering, procedural and practical constraints to these remedial options. Based on the RI/FS, the EPA will determine whether and what remedial actions are appropriate in accordance with criteria that take into account, among other factors, technical feasibility, effectiveness, cost, effects on the environment resulting from the remediation action, and acceptability of the relevant remedial option to the community. Each work product and plan in this process is subject to EPA approval. Internal consultation processes of the EPA will include consultation with state and other federal agencies and the two Indian Tribes bordering the site.

While the UAO was outstanding, two citizens of Washington State and members of the Colville Tribe commenced an enforcement proceeding under Section 310(a)(i) of the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) to enforce the UAO and to seek fines and penalties against Cominco for non-compliance. Cominco sought to have all claims dismissed on the basis that the court lacked jurisdiction because the CERCLA statute was not intended to govern the discharges of a facility occurring in another country. That case has proceeded through U.S. Federal District Court and the Federal Court of Appeals for the 9th Circuit. The 9th Circuit affirmed the District Court decision denying Cominco’s motion to dismiss the case on jurisdictional grounds and found that CERCLA could be applied to Cominco’s disposal practices in British Columbia because they may have had an effect in Washington State. The 9th Circuit has issued a stay of its decision pending the resolution of a further appeal by Cominco to the U.S. Supreme Court.

On February 27, 2007, Cominco filed a petition for review and reversal with the U.S. Supreme Court. Cominco’s petition was supported by amicus briefs filed by Canada, the Province of British Columbia, the Mining Association of Canada, the U.S. National Mining Association, the U.S. Association of Manufacturers, the Canadian and U.S. Chambers of Commerce and the Consumer Electronics Association. On June 4, 2007, the U.S. Supreme Court requested the Solicitor General to opine on the petition for review on behalf of the Administration.

By letter dated July 27, 2007, we received notification from the Colville Tribe that they have been appointed lead administrative trustee to the recently formed Upper Columbia/Lake Roosevelt Natural Resource Trustee Council comprised of the Colville Tribe, the Spokane Tribe, the State of Washington and the U.S. Department of Interior. We were advised that the primary purpose of the council is the integration and coordination of the assessment of potential natural resource damages during the on-going RI/FS at the site. We believe, and have so informed the council, that it is premature to conduct such studies until the RI/FS is complete.

There can be no assurance that the U.S. Supreme Court will agree to hear Cominco’s appeal or reverse the decision or that the withdrawal of the UAO and the settlement of the Agreement will be sufficient to resolve the matter or that Cominco or its affiliates will not be faced with further liability in relation to this matter. Until the Studies contemplated by the Agreement are completed, it is not possible to estimate the extent and cost, if any, of remediation or restoration that may be required. The Studies may conclude, on the basis of risk, cost, technical

feasibility or other grounds, that no remediation should be undertaken. If remediation is required, the cost of remediation may be material.

THE COMPANY

Teck Cominco Limited is the continuing company resulting from the merger in 1963 of three companies, Teck-Hughes Gold Mines Ltd., Lamaque Gold Mines Limited and Canadian Devonian Petroleum Ltd., incorporated in 1913, 1937 and 1951, respectively.

RECENT DEVELOPMENTS

Acquisition of Aur Resources Inc.

Pursuant to our offer dated July 17, 2007, we acquired approximately 93% of the outstanding common shares of Aur on August 22, 2007. In September 2007, we acquired the balance of the outstanding shares of Aur pursuant to a compulsory acquisition in accordance with the CBCA. In October 2007, Aur’s common shares were

voluntarily delisted from the Toronto Stock Exchange and the Santiago Stock Exchange and Aur ceased to be a reporting issuer in all provinces of Canada.

Aur is a Canadian company active in the acquisition, exploration, development and mining of mineral properties. Aur’s principal mining assets consist of its 76.5% shareholding interest in the Quebrada Blanca copper mine in Chile, its 90% shareholding interest in the Andacollo copper mine and the Andacollo hypogene copper-gold deposit under development in Chile and its 100% interest in the Duck Pond copper-zinc mine in Newfoundland, Canada.

For further information regarding Aur, please see the Business Acquisition Report dated October 29, 2007 incorporated by reference in this prospectus. Continuous disclosure documents for Aur can be found at Aur’s filer profile on SEDAR at www.sedar.com.

USE OF PROCEEDS

Unless otherwise indicated in the applicable prospectus supplement, we will use the net proceeds from the sale of the debt securities to repay existing indebtedness outstanding from time to time and for general corporate purposes. We may invest funds that we do not immediately require in short-term marketable securities.

EARNINGS COVERAGE

Earnings coverage ratios are included in this prospectus in accordance with Canadian disclosure requirements. They have been calculated on a consolidated basis using financial information prepared in accordance with Canadian generally accepted accounting principles and do not give pro forma effect to any offering of debt securities offered by this prospectus or to any change in indebtedness subsequent to the dates indicated below. For purposes of these calculations, reported net earnings have been increased by interest expense and income and mining taxes. The earnings coverage ratio is equal to net earnings, adjusted as described above, divided by interest expense. These ratios do not purport to be indicative of earnings coverage ratios for any future period.

The earnings coverage ratio for the year ended December 31, 2006 was 36.7 times interest expense. For the twelve-month period ended September 30, 2007, the earnings coverage ratio was 36.3 times interest expense. Our earnings for the year ended December 31, 2006 and the twelve-month period ended September 30, 2007 before interest expense, income and mining taxes, depreciation and amortization amounted to approximately $4.0 billion and $3.7 billion, respectively, which amounted to 39.3 times and 39.5 times our interest expense for those periods, respectively.

DESCRIPTION OF SHARE CAPITAL

We are authorized to issue an unlimited number of Class A common shares and Class B subordinate voting shares and an unlimited number of preference shares, issuable in series. As at October 25, 2007, there were outstanding 9,353,470 Class A common shares, 432,440,402 Class B subordinate voting shares (or 433,178,226 calculated on a fully diluted basis, excluding the conversion rights of holders of Class A common shares) and no preference shares.

Class A common shares carry the right to 100 votes per share. Class B subordinate voting shares carry the right to one vote per share. Each Class A common share is convertible, at the option of the holder, into one Class B subordinate voting share. In all other respects, the Class A common shares and Class B subordinate voting shares rank equally, including in respect of dividends and the right to receive the remaining property of the company upon dissolution. No dividends may be paid on the Class A common shares or the Class B subordinate voting shares unless all dividends on any preference shares outstanding have been paid. Subject to the rights, privileges, restrictions and conditions attaching to any preference shares, the holders of Class A common shares and Class B subordinate voting shares are entitled to dividends as may be declared by the board of directors of the company in their discretion out of funds legally available therefor.

The attributes of the Class B subordinate voting shares contain so-called “coattail provisions” which provide that, if an offer (an “Exclusionary Offer”) to purchase Class A common shares that is required to be made to all or substantially all holders thereof, is not made concurrently with an offer to purchase Class B subordinate voting shares on identical terms, then each Class B subordinate voting share will be convertible into one Class A common share. The Class B subordinate voting shares will not be convertible in the event that an Exclusionary Offer is not accepted by holders of a majority of the Class A common shares (excluding those shares held by the person making the Exclusionary Offer). If an offer to purchase Class A common shares does not, under applicable securities legislation or the requirements of any stock exchange having jurisdiction, constitute a “take-over bid” or is otherwise exempt from any requirement that such offer be made to all or substantially all holders of Class A common shares, the coattail provisions will not apply.

The voting rights attached to the outstanding Class B subordinate voting shares represent approximately 31.6% of the aggregate voting rights attached to the Class A common shares and Class B subordinate voting shares.

DESCRIPTION OF DEBT SECURITIES

In this section, the words “company”, “we”, “us” and “our” refer only to Teck Cominco Limited and not to any of our subsidiaries or joint ventures. The following description sets forth certain general terms and provisions of the debt securities. The particular terms and provisions of the series of debt securities offered by a prospectus supplement, and the extent to which the general terms and provisions described below may apply thereto, will be described in such prospectus supplement.

Unless otherwise specified in the applicable prospectus supplement, the debt securities will be issued under the trust indenture (the “indenture”) dated as of September 12, 2002 entered into between the company and The Bank of New York, as trustee (the “trustee”). A copy of the form of indenture has been filed with the SEC as an exhibit to the registration statement of which this prospectus forms a part and a copy of the executed indenture is also available on SEDAR at www.sedar.com. The following statements with respect to the indenture and the debt securities are brief summaries of certain provisions of the indenture and do not purport to be complete. For a more complete description, including the definition of any terms used but not defined under this section, prospective investors should refer to the indenture. Whenever we refer to particular provisions of the indenture, those provisions are qualified in their entirety by reference to the indenture.

We may from time to time issue debt securities and incur additional indebtedness otherwise than through the offering of debt securities pursuant to this prospectus.

General

The indenture does not limit the aggregate principal amount of debt securities (which may include debentures, notes or other evidences of indebtedness) which may be issued thereunder. It provides that debt securities may be issued from time to time in one or more series and may be denominated and payable in foreign currencies, including composite currencies. Special Canadian and United States federal income tax considerations applicable to any debt securities so denominated will be described in the prospectus supplement relating thereto. The debt securities offered pursuant to this prospectus will be limited to US$2,500,000,000 (or the equivalent in other currencies) aggregate principal amount. Unless otherwise indicated in the applicable prospectus supplement, the indenture also permits the company to increase the principal amount of any series of debt securities previously issued and to issue such increased principal amount.

The terms of the debt securities we may offer may differ from the general information provided below. In particular, certain covenants described below may not apply to certain debt securities we may offer under the indenture. We may issue debt securities with terms different from those of debt securities previously issued under the indenture.

The applicable prospectus supplement will set forth the specific terms relating to the debt securities of the series being offered and may include, without limitation, any of the following:

	•		the specific designation of the offered debt securities;

	•		the aggregate principal amount of the offered debt securities;

	•		the extent and manner, if any, to which payment on or in respect of the offered debt securities will be senior or will be subordinated to the prior payment of our other liabilities and obligations;

	•		the percentage or percentages of principal amount at which the offered debt securities will be issued;

	•		the date or dates, if any, on which the offered debt securities will mature and the portion (if less than all of the principal amount) of the offered debt securities to be payable upon declaration of acceleration of maturity;

	•		the rate or rates per annum (which may be fixed or variable) at which the offered debt securities will bear interest, if any, the date or dates from which any such interest will accrue (or the method by which such date or dates will be determined) and the dates on which any such interest will be payable and the regular record dates for any interest payable on the offered debt securities;

	•		any mandatory or optional redemption or sinking fund or analogous provisions, including the period or periods within which, the price or prices at which and the terms and conditions upon which the offered debt securities may be redeemed or purchased at the option of the company or otherwise;

	•		whether the offered debt securities will be issuable in whole or in part in the form of one or more registered global securities (“registered global securities”) and, if so, the identity of the depositary for such registered global securities;

	•		the denominations in which registered debt securities (“registered securities”) will be issuable, if other than denominations of US$1,000 and any integral multiple thereof;

	•		each place where the principal of and any premium and interest on the offered debt securities will be payable and each place where the offered debt securities may be presented for registration of transfer or exchange;

	•		if other than United States dollars, the foreign currency or the units based on or relating to foreign currencies in which the offered debt securities are denominated and/or in which the payment of the principal of and any premium and interest on the offered debt securities will or may be payable;

	•		any index formula or other method pursuant to which the amount of payments of principal of, and any premium and interest on, the offered debt securities will or may be determined;

	•		whether and under what circumstances we will pay Additional Amounts (as defined below under “– Payment of Additional Amounts”) on the offered debt securities in respect of certain taxes (and the terms of any such payment) and, if so, whether we will have the option to redeem the offered debt securities rather than pay the Additional Amounts (and the terms of any such option);

	•		the terms and conditions, if any, on which the debt securities may be convertible into or exchangeable for any other of our securities or securities of other entities;

	•		whether the payment of the offered debt securities will be guaranteed by any other person;

	•		whether the offered debt securities will have the benefit of any security interest created pursuant to the terms of the indenture; and

•

any other terms of the offered debt securities, including covenants and events of default which apply solely to the offered debt securities, or any covenants or events of default generally applicable to the debt securities which are not to apply to the offered debt securities.

Unless otherwise indicated in the applicable prospectus supplement, the indenture does not afford the holders the right to tender debt securities to the company for repurchase or provide for any increase in the rate or rates of interest at which the debt securities will bear interest in the event we should become involved in a highly leveraged transaction or in the event of a change in control of the company.

Our debt securities may be issued under the indenture bearing no interest or interest at a rate below the prevailing market rate at the time of issuance, to be offered and sold at a discount below their stated principal amount. The Canadian and United States federal income tax consequences and other special considerations applicable to any such discounted debt securities or other debt securities offered and sold at par which are treated as having been issued at a discount for Canadian and/or United States federal income tax purposes will be described in the prospectus supplement relating thereto.

Unless otherwise specified in the applicable prospectus supplement, upon completion of an offering of offered debt securities, we will advance the proceeds of such offering to our subsidiary, Cominco, and Cominco will issue us a note (a “Cominco note”) in the amount of such proceeds. The principal amount of such Cominco note, plus (i) accrued and unpaid interest thereon at least equal to accrued and unpaid interest on the applicable offered debt securities and (ii) other monetary obligations payable pursuant to the Cominco note, will become due and payable on demand by us or, upon an event of default under the indenture, on demand by us or our assignee. Any Cominco notes issued will be pledged in favor of the trustee for the benefit of the holders of the applicable offered debt securities. A breach under the collateral documents relating to any such pledge will be an event of default under the indenture. It will also be an event of default under the indenture if at any time following the termination of the collateral documents relating to any such pledge:

	•		Cominco or any successor thereto which has assumed Cominco’s obligations under any such pledge has been, for a period of not less than 30 consecutive days, the primary obligor or guarantor with respect to Indebtedness (as defined below under “– Certain Covenants”) in an aggregate amount which exceeds 10% of Consolidated Net Tangible Assets (as defined below under “– Certain Covenants”);

	•		we have not, within such 30 day period, created a security interest in favor of the trustee in another note or evidence of Indebtedness issued to us by Cominco or such successor in the same principal amount and substantially similar to such collateral documents that ranks equally and ratably with unsecured and unsubordinated Indebtedness of Cominco or such successor; and

	•		on the 30th day of such 30 day period Cominco or such successor was a Subsidiary (as defined below under “– Certain Covenants”).

As a result, for so long as this intercompany arrangement and pledge are in place, upon the occurrence of an event of default under the indenture, the trustee on behalf of the holders of the applicable offered debt securities will have the right to make a demand on the Cominco note and will have a claim against Cominco in an amount equal to the amount due under the applicable offered debt securities. Therefore, the applicable offered debt securities will in effect rank equally and ratably with any unsecured and unsubordinated debt issued or guaranteed by Cominco.

Ranking and Other Indebtedness

Except as indicated herein or in the applicable prospectus supplement, the debt securities will be unsecured obligations and will rank equally with all of our other unsecured and unsubordinated Indebtedness from time to time outstanding. The debt securities will be effectively subordinated to all Indebtedness and other liabilities of our subsidiaries (other than those of Cominco so long as the pledge of the Cominco note remains in place) and subordinated to all secured Indebtedness and other secured liabilities of Cominco to the extent of the assets securing

such Indebtedness and other liabilities. At September 30, 2007, the aggregate amount of the Indebtedness and trade payables of our subsidiaries (other than Cominco) and the secured Indebtedness of Cominco was approximately $713 million. In addition, Compañía Minera Antamina S.A., in which we have a 22.5% interest, had outstanding at September 30, 2007, US$733 million of revolving debt, trade payables and current taxes, our proportionate share of which is reflected in our consolidated balance sheet. Elk Valley Coal Partnership, in which we have a 40% partnership interest, has given an unsecured guarantee of up to $400 million of indebtedness of Fording Inc., which guarantee is limited in recourse against us to the assets of Elk Valley Coal Partnership. The debt securities will be effectively subordinated to the obligations of Elk Valley Coal Partnership under this guarantee.

Pledge Termination

Under the circumstances set forth below, we may terminate the pledge of a Cominco note.

If we elect to terminate the pledge of a Cominco note, we are obligated to notify each debt rating agency known to us which has assigned a rating to the applicable offered debt securities and which is designated by the SEC as a “Nationally Recognized Statistical Rating Organization” (a “Participating NRSRO”) and the trustee of our intention to exercise our option to terminate the pledge of such Cominco note at least 45 days prior to the proposed date of such termination (the “Release Date”). In order to effect the termination of the pledge of a Cominco note, on the proposed Release Date we are obligated to deliver to the trustee an officers’ certificate stating that we have satisfied each of the conditions listed below.

After delivery of such officers’ certificate, we may, at our option and without the consent of the holders of the applicable offered debt securities, permanently terminate the pledge of a Cominco note, provided that at the time of such termination:

	•		Cominco shall not be the primary obligor or guarantor with respect to any Indebtedness, other than Indebtedness which in the aggregate does not exceed an amount equal to 10% of Consolidated Net Tangible Assets;

	•		the rating assigned to the applicable offered debt securities by at least two Participating NRSRO’s (or if there is only one Participating NRSRO, by that one Participating NRSRO) is within one of the ratings categories assigned by them designating “investment grade” corporate debt securities;

	•		at least two Participating NRSRO’s (or if there is only one Participating NRSRO, that one Participating NRSRO) have affirmed that the rating assigned by them to the applicable offered debt securities shall not be downgraded as a result of the termination of the pledge, or notice thereof; and

	•		no default or event of default has occurred and is continuing under the indenture.

Form, Denomination, Exchange and Transfer

Unless otherwise indicated in the applicable prospectus supplement, the debt securities will be issued only in fully registered form without coupons and in denominations of US$1,000 or any integral multiple thereof. Debt securities may be presented for exchange and registered securities may be presented for registration of transfer in the manner, at the places and, subject to the restrictions set forth in the indenture and in the applicable prospectus supplement, without service charge, but upon payment of any taxes or other governmental charges due in connection therewith. The company has appointed the trustee as security registrar.

Payment

Unless otherwise indicated in the applicable prospectus supplement, payment of the principal of and any premium and interest on registered securities (other than registered global securities) will be made at the office or agency of the trustee at 101 Barclay Street, Floor 21 West, New York, New York 10286, Attention: Global Finance

Unit, to the persons in whose name such registered securities are registered at the close of business on the regular record date for such interest payment.

Registered Global Securities

The registered securities of a particular series may be issued in the form of one or more registered global securities which will be registered in the name of and be deposited with a depositary, or its nominee, each of which will be identified in the prospectus supplement relating to such series. Unless and until exchanged, in whole or in part, for debt securities in definitive registered form, a registered global security may not be transferred except as a whole by the depositary for such registered global security to a nominee of such depositary, by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor.

The specific terms of the depositary arrangement with respect to any portion of a particular series of debt securities to be represented by a registered global security will be described in the prospectus supplement relating to such series. The company anticipates that the following provisions will apply to all depositary arrangements.

Upon the issuance of a registered global security, the depositary therefor or its nominee will credit, on its book entry and registration system, the respective principal amounts of the debt securities represented by such registered global security to the accounts of such persons having accounts with such depositary or its nominee (“participants”) as will be designated by the underwriters, investment dealers or agents participating in the distribution of such debt securities, or by the company if such debt securities are offered and sold directly by the company. Ownership of beneficial interests in a registered global security will be limited to participants or persons that may hold beneficial interests through participants. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of such ownership will be effected only through, records maintained by the depositary therefor or its nominee (with respect to beneficial interests of participants) or by participants or persons that hold through participants (with respect to interests of persons other than participants).

So long as the depositary for a registered global security or its nominee is the registered owner thereof, such depositary or such nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by such registered global security for all purposes under the indenture. Except as provided below, owners of beneficial interests in a registered global security will not be entitled to have debt securities of the series represented by such registered global security registered in their names, will not receive or be entitled to receive physical delivery of debt securities of such series in definitive form and will not be considered the owners or holders thereof under the indenture.

Principal, premium, if any, and interest payments on a registered global security registered in the name of a depositary or its nominee will be made to such depositary or nominee, as the case may be, as the registered owner of such registered global security. None of the company, the trustee or any paying agent for debt securities of the series represented by such registered global security will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in such registered global security or for maintaining, supervising or reviewing any records relating to such beneficial interests.

We expect that the depositary for a registered global security or its nominee, upon receipt of any payment of principal, premium or interest, will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such registered global security as shown on the records of such depositary or its nominee. We also expect that payments by participants to owners of beneficial interests in such registered global security held through such participants will be governed by standing instructions and customary practices, as is now the case with debt securities held for the accounts of customers registered in “street name”, and will be the responsibility of such participants.

If the depositary for a registered global security representing debt securities of a particular series is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act and no successor depositary is appointed within 90 days after we receive notice or become aware of such condition, we will issue registered securities of such series in definitive form in exchange for such registered global security. In addition, we may at any time and in our sole discretion determine not to have the debt securities of a

particular series represented by one or more registered global securities and, in such event, will issue registered securities of such series in definitive form in exchange for all of the registered global securities representing debt securities of such series.

Negative Pledge

We have covenanted under the indenture that for so long as any of our debt securities under the indenture are outstanding, and subject to the provisions of the indenture, we will not, and we will not permit any Restricted Subsidiary to, create, incur, issue, assume or otherwise have outstanding any Mortgage on or over any Principal Property now owned or hereafter acquired by Teck Cominco or a Restricted Subsidiary to secure any Indebtedness, or on shares of stock or Indebtedness of any Restricted Subsidiary now owned or hereafter acquired by Teck Cominco or a Restricted Subsidiary to secure any Indebtedness, unless at the time thereof or prior thereto the debt securities then outstanding under the indenture (together with, if and to the extent we so determine, any other Indebtedness then existing or thereafter created) are secured equally and rateably with (or prior to) any and all such Indebtedness for so long as such Indebtedness is so secured by such Mortgage; provided, however, such negative pledge will not apply to or operate to prevent or restrict the following permitted encumbrances:

	(1)		any Mortgage on property, shares of stock or Indebtedness of any person existing at the time such person becomes a Restricted Subsidiary or created, incurred, issued or assumed in connection with the acquisition of any such person;

	(2)		any Mortgage on any Principal Property created, incurred, issued or assumed at or prior to the time such property became a Principal Property or existing at the time of acquisition of such Principal Property by Teck Cominco or a Restricted Subsidiary, whether or not assumed by Teck Cominco or such Restricted Subsidiary; provided that no such Mortgage will extend to any other Principal Property of Teck Cominco or any Restricted Subsidiary;

	(3)		any Mortgage on all or any part of any Principal Property (including any improvements or additions to improvements on a Principal Property) hereafter acquired, developed, expanded or constructed by Teck Cominco or any Restricted Subsidiary to secure the payment of all or any part of the purchase price, cost of acquisition or cost of development, expansion or construction of such Principal Property or of improvements or additions to improvements thereon (or to secure

			any Indebtedness incurred by Teck Cominco or a Restricted Subsidiary for the purpose of financing all or any part of the purchase price, cost of acquisition or cost of development, expansion or construction thereof or of improvements or additions to improvements thereon) created prior to, at the time of, or within 360 days after the later of, the acquisition, development, expansion or completion of construction (including construction of improvements or additions to improvements thereon), or commencement of full operation of such Principal Property; provided that no such Mortgage will extend to any other Principal Property of Teck Cominco or a Restricted Subsidiary other than, in the case of any such construction, improvement, development, expansion or addition to improvement, all or any part of any other Principal Property on which the Principal Property so constructed, developed or expanded, or the improvement or addition to improvement, is located;

	(4)		any Mortgage on any Principal Property of any Restricted Subsidiary to secure Indebtedness owing by it to Teck Cominco or to another Restricted Subsidiary;

	(5)		any Mortgage on any Principal Property of Teck Cominco to secure Indebtedness owing by it to a Restricted Subsidiary;

	(6)		any Mortgage on any Principal Property or other assets of Teck Cominco or any Restricted Subsidiary existing on the date of the indenture, or arising thereafter pursuant to contractual commitments entered into prior to the date of the indenture;

	(7)		any Mortgage on any Principal Property or other assets of Teck Cominco or any Restricted Subsidiary created for the sole purpose of extending, renewing, altering or refunding any of the foregoing Mortgages, provided that the Indebtedness secured thereby will not exceed the principal amount of Indebtedness so secured at the time of such extension, renewal, alteration or refunding, plus an amount necessary to pay fees and expenses, including premiums, related to such extensions, renewals, alterations or refundings, and that such extension, renewal, alteration or refunding Mortgage will be limited to all or any part of the same Principal Property and improvements and additions to improvements thereon and/or shares of stock and Indebtedness of a Restricted Subsidiary which secured the Mortgage extended, renewed, altered or refunded or either of such property or shares of stock or Indebtedness; or

	(8)		any Mortgage on any Principal Property or on any shares of stock or Indebtedness of any Restricted Subsidiary created, incurred, issued or assumed to secure Indebtedness of Teck Cominco or any Restricted Subsidiary, which would otherwise be subject to the foregoing restrictions, in an aggregate amount which, together with the aggregate principal amount of other Indebtedness secured by Mortgages on any Principal Property or on any shares of stock or Indebtedness of any Restricted Subsidiary then outstanding (excluding Indebtedness secured by Mortgages permitted under the foregoing exceptions) and the Attributable Debt in respect of all Sale and Leaseback Transactions entered into after the date of the indenture (not including Attributable Debt in respect of any such Sale and Leaseback Transactions the proceeds of which are applied as set forth below under “– Limitation on Sale and Leaseback Transactions”) would not then exceed 10% of Consolidated Net Tangible Assets.

For purposes of the foregoing and the covenant below entitled “– Limitation on Sale and Leaseback Transactions”, the giving of a guarantee which is secured by a Mortgage on a Principal Property or on shares of stock or Indebtedness of any Restricted Subsidiary, and the creation of a Mortgage on a Principal Property or on shares of stock or Indebtedness of any Restricted Subsidiary to secure Indebtedness which existed prior to the creation of such Mortgage, will be deemed to involve the creation of Indebtedness in an amount equal to the principal amount guaranteed or secured by such Mortgage but the amount of Indebtedness secured by Mortgages on any Principal Property and shares of stock and Indebtedness of Restricted Subsidiaries will be computed without cumulating the underlying Indebtedness with any guarantee thereof or Mortgage securing the same.

The following types of transactions will not be deemed to be Mortgages securing Indebtedness: any acquisition by Teck Cominco or any Restricted Subsidiary of any property or assets subject to any reservation or

exception under the terms of which any vendor, lessor or assignor creates, reserves or excepts or has created, reserved or excepted an interest in base metals, precious metals, oil, gas or any other mineral or timber in place or the proceeds thereof; any conveyance or assignment whereby Teck Cominco or any Restricted Subsidiary conveys or assigns to any person or persons an interest in base metals, precious metals, oil, gas or any other mineral or timber in place or the proceeds thereof; or any Mortgage upon any property or assets owned or leased by Teck Cominco or any Restricted Subsidiary or in which Teck Cominco or any Restricted Subsidiary owns an interest to secure to the person or persons paying the expenses of developing or conducting operations for the recovery, storage, transportation or sale of the mineral resources of the said property (or property with which it is utilized) the payment to such person or persons of Teck Cominco’s or the Restricted Subsidiary’s proportionate part of such development or operating expense; provided that such Mortgage does not extend beyond such property or assets and that the principal amount of any Indebtedness secured thereby does not exceed the amount of such expenses.

Limitation on Sale and Leaseback Transactions

Sale and Leaseback Transactions by Teck Cominco or any Restricted Subsidiary of any Principal Property are prohibited by the indenture unless (1) such transaction involves a lease or right to possession or use for a temporary period not to exceed three years following such transaction, by the end of which it is intended that the use of such property by the lessee will be discontinued; or (2) immediately prior to the entering into of such transaction, Teck Cominco or such Restricted Subsidiary could create a Mortgage on such Principal Property securing Indebtedness in an amount equal to the Attributable Debt with respect to the particular Sale and Leaseback Transaction; or (3) the proceeds of such transaction (a) are equal to or greater than the fair market value (as determined by our board of directors) of the Principal Property so sold and leased back at the time of entering into such Sale and Leaseback Transaction and (b) within 180 days after such transaction, are applied to either the payment of all or any part of the purchase price, cost of acquisition, cost of development, cost of expansion or cost of construction of a Principal Property or cost of improvements or additions to improvements thereon or the prepayment (other than mandatory prepayment) of Funded Debt of Teck Cominco or a Restricted Subsidiary (other than Funded Debt held by Teck Cominco or any Restricted Subsidiary).

Consolidation, Amalgamation and Merger and Sale of Assets

We may not consolidate or amalgamate with or merge into or enter into any statutory arrangement with any other person, or, directly or indirectly, convey, transfer or lease all or substantially all our properties and assets to any person, unless:

	•		the person formed by or continuing from such consolidation or amalgamation or into which we are merged or with which we enter into such statutory arrangement or the person which acquires or leases all or substantially all of our properties and assets is organized and existing under the laws of the United States, any state thereof or the District of Columbia or the laws of Canada or any province or territory thereof, or, if such consolidation, amalgamation, merger, statutory arrangement or other transaction would not impair the rights of the holders of the debt securities under the indenture, in any other country, provided that if such successor person is organized under the laws of a jurisdiction other than the United States, any state thereof or the District of Columbia, or the laws of Canada or any province or territory thereof, the successor person assumes our obligations under the debt securities and the indenture to pay Additional Amounts (as defined below under “– Payment of Additional Amounts”), and, in connection therewith, for purposes of the provisions described in “– Payment of Additional Amounts” and “– Tax Redemption” below, the reference to such successor jurisdiction is added with “Canada” and “Canadian” in each place that “Canada” or “Canadian” appears therein;

	•		the successor person expressly assumes or assumes by operation of law all of our obligations under our debt securities and under the indenture;

	•		immediately before and after giving effect to such transaction, no event of default and no event which, after notice or lapse of time or both, would become an event of default, will have happened and be continuing; and

•

certain other conditions are met.

If, as a result of any such transaction, any of our Principal Properties become subject to a Mortgage, then, unless such Mortgage could be created pursuant to the indenture provisions described under “– Negative Pledge” above without equally and ratably securing our debt securities, we, simultaneously with or prior to such transaction, will cause our debt securities to be secured equally and ratably with or prior to the Indebtedness secured by such Mortgage.

Payment of Additional Amounts

Unless otherwise specified in the applicable prospectus supplement, all payments made by or on behalf of us under or with respect to any series of our debt securities issued under the indenture will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including penalties, interest and other liabilities related thereto) imposed or levied by or on behalf of the Government of Canada or any province or territory thereof or by any authority or agency therein or thereof having power to tax (hereinafter “Canadian Taxes”), unless we are required to withhold or deduct Canadian Taxes by law or by the interpretation or administration thereof by the relevant government authority or agency. If we are so required to withhold or deduct any amount for or on account of Canadian Taxes from any payment made under or with respect to the debt securities issued under the indenture, we will pay to each holder of such debt securities as additional interest such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each such holder after such withholding or deduction (and after deducting any Canadian Taxes on such Additional Amounts) will not be less than the amount such holder would have received if such Canadian Taxes had not been withheld or deducted. However, no Additional Amounts will be payable with respect to a payment made to a debt securities holder (such holder, an “Excluded Holder”):

	•		with which we do not deal at arm’s length (for the purposes of the Income Tax Act (Canada)) at the time of the making of such payment;

	•		which is subject to such Canadian Taxes by reason of the debt securities holder being a resident, domicile or national of, or engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some connection with Canada or any province or territory thereof otherwise than by the mere holding of the debt securities or the receipt of payments thereunder;

	•		which is subject to such Canadian Taxes by reason of the debt securities holder’s failure to comply with any certification, identification, documentation or other reporting requirements if compliance is required by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such Canadian Taxes; or

	•		which is subject to such Canadian Taxes because the debt securities holder is not entitled to the benefit of an applicable treaty by reason of the legal nature of such holder.

We will also:

	•		make such withholding or deduction; and

	•		remit the full amount deducted or withheld to the relevant authority in accordance with applicable law.

We will furnish to the holders of the debt securities, within 60 days after the date the payment of any Canadian Taxes is due pursuant to applicable law, certified copies of tax receipts or other documents evidencing such payment by us.

We will indemnify and hold harmless each holder of debt securities (other than an Excluded Holder) and upon written request reimburse each such holder for the amount (excluding any Additional Amounts that have previously been paid by us) of:

	•		any Canadian Taxes so levied or imposed and paid by such holder as a result of payments made under or with respect to the debt securities;

	•		any liability (including penalties, interest and expenses) arising therefrom or with respect thereto; and

	•		any Canadian Taxes imposed with respect to any reimbursement under the preceding two bullet points, but excluding any such Canadian Taxes on such holder’s net income.

Wherever in the indenture there is mentioned, in any context, the payment of principal (and premium, if any), interest, if any, or any other amount payable under or with respect to a debt security, such mention will be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

Tax Redemption

Unless otherwise specified in the applicable prospectus supplement, a series of our debt securities will be subject to redemption at any time, in whole but not in part, at a redemption price equal to the principal amount thereof together with accrued and unpaid interest to the date fixed for redemption, upon the giving of a notice as described below, if we determine that:

•

as a result of any change in or amendment to the laws (or any regulations or rulings promulgated thereunder) of Canada or of any political subdivision or taxing authority thereof or therein affecting taxation, or any change in official position regarding the application or interpretation of such laws, regulations or rulings by any legislative body, court, governmental agency or regulatory authority (including a holding by a court of competent jurisdiction), which change or amendment is announced or becomes effective on or after the date of this prospectus, we have or will become obligated to pay, on the next succeeding date on which interest is due, Additional Amounts; or

•

on or after the date of this prospectus, any action has been taken by any taxing authority of, or any decision has been rendered by a court of competent jurisdiction in, Canada or any political subdivision or taxing authority thereof or therein, including any of those actions specified in the paragraph immediately above, whether or not such action was taken or decision was rendered with respect to us, or any change, amendment, application or interpretation will be officially proposed, which, in any such case, in the written opinion of our legal counsel, will result in our becoming obligated to pay, on the next succeeding date on which interest is due, Additional Amounts with respect to any debt security of such series,

and, in any such case, we, in our business judgment, determine that such obligation cannot be avoided by the use of reasonable measures available to us.

In the event that we elect to redeem a series of our debt securities pursuant to the provisions set forth in the preceding paragraph, we will deliver to the trustee an officers’ certificate, signed by two authorized officers, stating that we are entitled to redeem such series of our debt securities pursuant to their terms.

Notice of intention to redeem such series of our debt securities will be given not more than 60 nor less than 30 days prior to the date fixed for redemption and will specify the date fixed for redemption.

Provision of Financial Information

We will file with the trustee, within 15 days after we file them with the SEC, copies, which may be in electronic format, of our annual report and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. Notwithstanding that we may not be required to remain subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the SEC, we will continue to provide the trustee:

•

within 140 days after the end of each fiscal year, the information required to be contained in annual reports on Form 20-F, Form 40-F or Form 10-K as applicable (or any successor form); and

•

within 60 days after the end of each of the first three fiscal quarters of each fiscal year, the information required to be contained in reports on Form 6-K (or any successor form) which, regardless of applicable requirements will, at a minimum, contain such information required to be provided in quarterly reports under the laws of Canada or any province thereof to security holders of a corporation with securities listed on the Toronto Stock Exchange, whether or not we have any of our securities listed on such exchange.

Such information will be prepared in accordance with Canadian disclosure requirements and GAAP; provided, however, that we will not be obligated to file such report with the SEC if the SEC does not permit such filings.

Events of Default

The following are summaries of events of default under the indenture with respect to debt securities of any series:

	•		default in the payment of any interest on any debt securities of that series when such interest becomes due and payable, and such default is continued for 30 days;

	•		default in the payment of the principal of (or premium, if any, on) any debt securities of that series when it becomes due and payable;

	•		default in the performance, or breach, of any of the covenants of the company in the indenture in respect of the debt securities of that series and described above under “– Consolidation, Amalgamation and Merger and Sale of Assets”;

	•		default in the performance, or breach, of any other covenant of the company in the indenture in respect of the debt securities of that series, and such default or breach is continued for 60 days after written notice to us as provided in the indenture;

	•		if an event of default (as defined in any indenture or instrument under which we or one of our Restricted Subsidiaries has at the time of the indenture or will thereafter have outstanding any Indebtedness) has occurred and is continuing, or Teck Cominco or any Restricted Subsidiary has failed to pay principal amounts with respect to such Indebtedness at maturity and such event of default or failure to pay has resulted in Indebtedness under such indentures or instruments being declared due, payable or otherwise being accelerated, in either event so that an amount in excess of the greater of US$50,000,000 and 2% of our Shareholders’ Equity will be or become due, payable and accelerated upon such declaration or prior to the date on which the same would otherwise have become due, payable and accelerated (the “accelerated indebtedness”), and such acceleration will not be rescinded or annulled, or such event of default or failure to pay under such indenture or instrument will not be remedied or cured, whether by payment or otherwise, or waived by the holders of such accelerated indebtedness, then (i) if the accelerated indebtedness will be as a result of an event of default which is not related to the failure to pay principal or

			interest on the terms, at the times, and on the conditions set out in any such indenture or instrument, it will not be considered an event of default for purposes of the indenture governing our debt securities until 30 days after such Indebtedness has been accelerated, or (ii) if the accelerated indebtedness will occur as a result of such failure to pay principal or interest or as a result of an event of default which is related to the failure to pay principal or interest on the terms, at the times, and on the conditions set out in any such indenture or instrument, then (A) if such accelerated indebtedness is, by its terms, non-recourse to us or our Restricted Subsidiaries, it will not be considered an event of default for purposes of the indenture governing our debt securities; or (B) if such accelerated indebtedness is recourse to us or our Restricted Subsidiaries, any requirement in connection with such failure to pay or event of default for the giving of notice or the lapse of time or the happening of any further condition, event or act under such other indenture or instrument in connection with such failure to pay principal or an event of default will be applicable together with an additional seven days before being considered an event of default for purposes of the indenture;

	•		certain events of bankruptcy, insolvency or reorganization occur;

	•		certain events of default concerning the collateral documents relating to the pledge described above under “– General”; and

	•		any other events of default provided with respect to debt securities of that series.

If an event of default with respect to any series of the debt securities occurs and is continuing, unless the principal amount of all of the debt securities of that series will have already become due and payable, the trustee may, in its discretion, and will upon request in writing made by the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of such affected series, declare by written notice to us as provided in the indenture, the principal amount of all debt securities of such affected series and all accrued interest thereon to be immediately due and payable. However, at any time after a declaration of acceleration with respect to the debt securities has been made and before a judgment or decree for payment of the money due has been obtained, the holders of a majority in aggregate principal amount of the outstanding debt securities of that series may, under certain circumstances, rescind and annul such declaration.

Except in cases of default where the trustee is required to exercise those rights and powers vested in it by the indenture, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs, the trustee is not required to take any action under the indenture at the request of any holders of the debt securities unless the holders offer the trustee protection from expenses and liability satisfactory to the trustee (called an “indemnity”). If such indemnity is provided, the holders of a majority in aggregate principal amount of the outstanding debt securities may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee and these majority holders may also direct the trustee to perform or exercise any trust or power granted to the trustee under the indenture with respect to the debt securities.

No holder of debt securities of any series will have any right to institute any proceeding with respect to the indenture, or for the appointment of a receiver or a trustee or for any other remedy thereunder, unless:

	(1)		such holder has previously given to the trustee written notice that an event of default has occurred with respect to the debt securities of such series;

	(2)		the holders of at least 25% in aggregate principal amount of the outstanding debt securities of such series make a written request that the trustee take action because of the default, and such holder or holders offer an indemnity satisfactory to the trustee against the cost and other liabilities of taking that action; and

	(3)		the trustee has not received from the holders of a majority in aggregate principal amount of the outstanding debt securities of such series a direction inconsistent with such request and has failed to take any action for 60 days after receipt of the above notice, request and direction.

However, such above-mentioned limitations do not apply to a suit instituted by the holder of a debt security for the enforcement of payment of the principal of, or any premium, if any, or interest on such debt securities on or after the applicable due date specified in such debt securities.

The trustee may withhold notice of any continuing default from the holders of the debt securities (except a default in the payment of principal (or premium, if any) or interest, if any, if it determines in good faith that withholding notice is in the interest of the holders.

Every year we will furnish to the trustee a written statement of certain of our officers certifying that to their knowledge we are in compliance with the indenture and the debt securities or, if not, specifying any known default.

Modification and Waiver

Modifications and amendments of the indenture may be made by us and the trustee with the consent of the holders of a majority in principal amount of the outstanding debt securities of each series issued under the indenture affected by such modification or amendment; provided, however, that no such modification or amendment may, without the consent of the holder of each outstanding debt security of such affected series:

	•		change the stated maturity of the principal of (or premium, if any) or any installment of interest, if any, on any debt security;

	•		change any of our obligations to pay Additional Amounts (except under certain circumstances provided in the indenture);

	•		reduce the principal amount of (or premium, if any), or rate of interest, if any, on any debt security;

	•		reduce the amount of principal of a debt security payable upon acceleration of the maturity thereof or the amount thereof provable in bankruptcy or adversely affect any right of repayment at the option of any holder of debt securities;

	•		change the place of payment;

	•		change the currency of payment of principal of (or premium, if any) or interest, if any, on any debt security;

	•		adversely affect any right to convert or exchange any debt security;

	•		impair the right to institute suit for the enforcement of any payment on or with respect to any debt security;

	•		reduce the voting or quorum requirements relating to meetings of holders of debt securities;

	•		reduce the percentage of aggregate principal amount of outstanding debt securities of such series, the consent of the holders of which is required for modification or amendment of the applicable indenture provisions or for waiver of compliance with certain provisions of the indenture or for waiver of certain defaults; or

	•		modify any provisions of the indenture relating to the modification and amendment of the indenture or the waiver of past defaults of covenants except as otherwise specified in the indenture.

The holders of a majority in principal amount of our outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive, insofar as that series is concerned, compliance by us with

certain restrictive provisions of the indenture. The holders of a majority in principal amount of outstanding debt securities of any series may waive any past default under the indenture with respect to that series, except a default in the payment of the principal of (or premium, if any) and interest, if any, on any debt security of that series or in respect of a provision which under the indenture cannot be modified or amended without the consent of the holder of each outstanding debt security of that series. The indenture or the debt securities may be amended or supplemented, without the consent of any holder of such debt securities, in order to, among other things, cure any ambiguity or inconsistency or to make any change, in any case, that would not adversely affect any holder of such debt securities.

Defeasance and Covenant Defeasance

Unless otherwise specified in the applicable prospectus supplement, the indenture provides that, at our option, we will be discharged from any and all obligations in respect of the outstanding debt securities of any series upon irrevocable deposit with the trustee, in trust, of money and/or U.S. government securities which will provide money in an amount sufficient in the opinion of a nationally recognized firm of financial advisers or independent chartered accountants as evidenced by a certificate of an officer of the company delivered to the trustee to pay the principal of (and premium, if any) and interest, if any, on the outstanding debt securities of such series (hereinafter referred to as a “defeasance”) (except with respect to the authentication, transfer, exchange or replacement of our debt securities or the maintenance of a place of payment and certain other obligations set forth in the indenture). Such trust may only be established if, among other things:

	•		we have delivered to the trustee an opinion of counsel in the United States stating that (i) we have received from, or there has been published by, the United States Internal Revenue Service a ruling, or (ii) since the date of execution of the indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that the holders of the outstanding debt securities of such series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred;

	•		we have delivered to the trustee an opinion of counsel in Canada or a ruling from the Canada Revenue Agency to the effect that the holders of the outstanding debt securities of such series will not recognize income, gain or loss for Canadian federal, provincial or territorial income or other Canadian tax purposes as a result of such defeasance and will be subject to Canadian federal, provincial or territorial income and other Canadian tax on the same amounts, in the same manner and at the same times as would have been the case had such defeasance not occurred (and for the purposes of such opinion, such Canadian counsel will assume that holders of the outstanding debt securities of such series include holders who are not resident in Canada);

	•		no event of default or event that, with the passing of time or the giving of notice, or both, will constitute an event of default will have occurred and be continuing on the date of such deposit;

	•		we are not an “insolvent person” within the meaning of the Bankruptcy and Insolvency Act (Canada) on the date of such deposit and after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally; and

	•		other customary conditions precedent are satisfied.

We may exercise our defeasance option notwithstanding our prior exercise of our covenant defeasance option described in the following paragraph if we meet the conditions described in the preceding paragraph at the time we exercise the defeasance option.

The indenture provides that, at our option, unless and until we have exercised our defeasance option described above, we may omit to comply with the covenants described under “– Negative Pledge” and “– Limitation on Sale and Leaseback Transactions”, and certain aspects of the covenant described under “– Consolidation,

Amalgamation, Merger and Sale of Assets” and certain other covenants and such omission will not be deemed to be an event of default under the indenture and our outstanding debt securities upon irrevocable deposit with the trustee, in trust, of money and/or U.S. government securities which will provide money in an amount sufficient in the opinion of a nationally recognized firm of financial advisers or independent chartered accountants as evidenced by a certificate of an officer of the company delivered to the trustee to pay the principal of (and premium, if any) and interest, if any, on the outstanding debt securities (hereinafter referred to as “covenant defeasance”). If we exercise our covenant defeasance option, the obligations under the indenture other than with respect to such covenants and the events of default other than with respect to such covenants will remain in full force and effect. Such trust may only be established if, among other things:

	•		we have delivered to the trustee an opinion of counsel in the United States to the effect that the holders of our outstanding debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred;

	•		we have delivered to the trustee an opinion of counsel in Canada or a ruling from the Canada Revenue Agency to the effect that the holders of our outstanding debt securities will not recognize income, gain or loss for Canadian federal, provincial or territorial income or other Canadian tax purposes as a result of such covenant defeasance and will be subject to Canadian federal, provincial or territorial income and other Canadian tax on the same amounts, in the same manner and at the same times as would have been the case had such covenant defeasance not occurred (and for the purposes of such opinion, such Canadian counsel will assume that holders of our outstanding debt securities include holders who are not resident in Canada);

	•		no event of default or event that, with the passing of time or the giving of notice, or both, will constitute an event of default will have occurred and be continuing on the date of such deposit;

	•		we are not an “insolvent person” within the meaning of the Bankruptcy and Insolvency Act (Canada) on the date of such deposit and after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally; and

	•		other customary conditions precedent are satisfied.

Governing Law

The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

Consent to Service

Under the indenture, Teck Cominco has irrevocably appointed CT Corporation System, 111 — 8th Avenue, 13th Floor, New York, New York 10011, as its authorized agent upon which process may be served in any suit or proceeding arising out of or relating to the indenture or the debt securities that may be instituted in any federal or New York state court located in the Borough of Manhattan, in the City of New York, or brought by the trustee (whether in its individual capacity or in its capacity as trustee under the indenture), and will irrevocably submit to the non-exclusive jurisdiction of such courts.

Discharge of the Indenture

We may satisfy and discharge our obligations under the indenture with respect to the debt securities by delivering to the trustee for cancellation all outstanding debt securities or by depositing with the trustee or the paying agent, after the debt securities have become due and payable, whether at stated maturity, on any redemption

date or otherwise, cash sufficient to pay all of the outstanding debt securities and pay all other sums payable under the indenture by us.

Enforceability of Judgments

We are incorporated under and governed by the laws of Canada. Many of our assets are located outside the United States and most of our directors and officers and some of the experts named in this prospectus are not residents of the United States. As a result, it may be difficult for you to effect service within the United States upon us and upon those directors, officers and experts, or to realize in the United States upon judgments of courts of the United States predicated upon our civil liability and the civil liability of our directors, officers or experts under the United States federal securities laws. We have been advised by our Canadian counsel, Lang Michener LLP, that there is doubt as to the enforceability in Canada by a court in original actions, or in actions to enforce judgments in United States courts, of civil liabilities predicated upon United States federal securities laws.

CERTAIN INCOME TAX CONSEQUENCES

The applicable prospectus supplement will describe to an investor who is a non-resident of Canada certain Canadian federal income tax consequences of acquiring any debt securities offered thereunder, including whether the payments of principal, premium (if any) and interest will be subject to Canadian non-resident withholding tax. The applicable prospectus supplement will also describe certain United States federal income tax consequences of the acquisition, ownership and disposition of any debt securities offered thereunder by an initial investor who is a United States person (within the meaning of the United States Internal Revenue Code).

PLAN OF DISTRIBUTION

We may sell the debt securities to or through underwriters or dealers, and also may sell the debt securities to one or more other purchasers directly or through agents.

The applicable prospectus supplement will set forth the terms of the offering relating to the particular debt securities, including, to the extent applicable, the name or names of any underwriters or agents, the initial public offering price or prices of the offered debt securities, the proceeds to us from the sale of the offered debt securities, any underwriting discount or commission and any discounts, concessions or commissions allowed or reallowed or paid by any underwriter to other dealers. Any initial public offering price and any discounts, concessions or commissions allowed or reallowed or paid to dealers may be changed from time to time.

The debt securities may be sold from time to time in one or more transactions at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at prices to be negotiated with purchasers.

In connection with the sale of debt securities, underwriters may receive compensation from us or from purchasers of debt securities for whom they may act as agents in the form of concessions or commissions. Underwriters, dealers and agents that participate in the distribution of debt securities may be deemed to be underwriters and any commissions received by them from us and any profit on the resale of debt securities by them may be deemed to be underwriting commissions under the U.S. Securities Act of 1933, as amended (the “Securities Act”).

If so indicated in the applicable prospectus supplement, we may authorize dealers or other persons acting as the company’s agents to solicit offers by certain institutions to purchase the offered debt securities directly from the company pursuant to contracts providing for payment and delivery on a future date. Such contracts will be subject only to the conditions set forth in such prospectus supplement, which will also set forth the commission payable for solicitation of such contracts.

Underwriters, dealers and agents who participate in the distribution of the debt securities may be entitled under agreements to be entered into with us to indemnification by us against certain liabilities, including liabilities

under the Securities Act, or to contributions with respect to payments which such underwriters, dealers, or agents may be required to make in respect thereof. Such underwriters, dealers and agents may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

In connection with any offering of debt securities, the underwriters may over-allot or effect transactions which stabilize or maintain the market price of the debt securities offered at a level above that which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time.

The debt securities will not be qualified for sale under the securities laws of Canada or any province or territory of Canada, unless the applicable prospectus supplement indicates otherwise with respect to the offered debt securities, and may not be offered or sold, directly or indirectly, in Canada or to residents of Canada in contravention of the securities laws of any province or territory of Canada. Each underwriter and each dealer participating in the distribution of offered debt securities will agree that, unless the applicable prospectus supplement indicates otherwise, it will not, directly or indirectly, offer, sell or deliver any such offered debt securities purchased by it in connection with such distribution in Canada or to residents of Canada in contravention of the securities laws of any province or territory of Canada.

Each series of debt securities will be a new issue of debt securities with no established trading market. Unless otherwise specified in the applicable prospectus supplement relating to a series of debt securities, the debt securities will not be listed on any securities exchange or automated quotation system and you may not be able to resell the debt securities purchased. Certain broker-dealers may make a market in the debt securities, but will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given that any broker-dealer will make a market in the debt securities of any series or as to the liquidity of the trading market for the debt securities of any series.

LEGAL MATTERS

Unless otherwise specified in the applicable prospectus supplement, certain matters of Canadian law will be passed upon for the company by Lang Michener LLP, Toronto and Vancouver, Canada. Certain matters of United States law will be passed upon for the company by Paul, Weiss, Rifkind, Wharton & Garrison LLP, New York, New York. In addition, certain matters of United States law will be passed upon for the underwriters by Shearman & Sterling LLP, Toronto, Canada.

The partners and associates of Lang Michener LLP and the individuals named under the heading “Experts” as a group beneficially own, directly and indirectly, less than 1% of any class of our securities.

PART II

INFORMATION NOT REQUIRED TO BE DELIVERED
TO OFFEREES OR PURCHASERS

Indemnification

Under the Canada Business Corporations Act (the “CBCA”), Teck Cominco Limited (the “Registrant”) may indemnify a present or former director or officer of the Registrant or another individual who acts or acted at the Registrant’s request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of that association with the Registrant or the other entity. The Registrant may not indemnify an individual unless the individual acted honestly and in good faith with a view to the best interests of the Registrant, or, as the case may be, to the best interests of the other entity for which the individual acted as a director or officer or in a similar capacity at the Registrant’s request and in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the individual had reasonable grounds for believing that the conduct was lawful. The indemnification may be made in connection with a derivative action only with court approval. The aforementioned individuals are entitled to indemnification from the Registrant as a matter of right if they were not judged by the court or other competent authority to have committed any fault or omitted to do anything that the individual ought to have done and they fulfill the conditions set out above. The Registrant may advance moneys to the individual for the costs, charges and expenses of a proceeding; however, the individual shall repay the moneys if the individual does not fulfill the conditions set out above.

The by-laws of the Registrant provide that, subject to the limitations contained in the CBCA, the Registrant shall indemnify a director or officer, a former director or officer, or a person who acts or acted at the Registrant’s request as a director or officer of a body corporate of which the Registrant is or was a shareholder or creditor (or a person who undertakes or has undertaken any liability on behalf of the Registrant or any such body corporate) and his heirs and legal representatives against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by him in respect of any civil, criminal or administrative action or proceeding to which he was made a party by reason of being or having been a director or officer of the Registrant or such body corporate, if he acted honestly and in good faith with a view to the best interests of the Registrant, and in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, he had reasonable grounds for believing that his conduct was lawful. The by-laws of the Registrant also provide that the Registrant shall also indemnify such a person in such other circumstances as the CBCA permits or requires.

The by-laws of the Registrant provide that the Registrant may, subject to the limitations contained in the CBCA, purchase and maintain insurance for the benefit of any person referred to in the foregoing paragraph. The Registrant has purchased third party director and officer liability insurance.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable.
