Units
Warrants

Silver Wheaton Corp. ("Silver Wheaton" or the "Corporation") may offer and sell from time to time, common shares (the "Common Shares"), preferred shares (the "Preferred Shares"), debt securities (the "Debt Securities"), subscription receipts (the "Subscription Receipts"), units (the "Units") and warrants (the "Warrants") (all of the foregoing, collectively, the "Securities") or any combination thereof in one or more series or issuances up to an aggregate total offering price of US$2,000,000,000 (or the equivalent thereof in other currencies) during the 25 month period that this short form base shelf prospectus (the "Prospectus"), including any amendments thereto, remains effective. The Securities may be offered separately or together, in amounts, at prices and on terms to be determined based on market conditions at the time of sale and set forth in an accompanying shelf prospectus supplement (a "Prospectus Supplement").

Silver Wheaton is permitted, under a multijurisdictional disclosure system adopted by the securities regulatory authorities in Canada and the United States, to prepare this Prospectus in accordance with the disclosure requirements of Canada. Prospective investors in the United States should be aware that such requirements are different from those of the United States. The financial statements incorporated by reference herein have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS") and may be subject to Canadian auditing and independence standards and thus may not be comparable to financial statements of United States companies.

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely by the fact that the Corporation is incorporated under the laws of Ontario, Canada, that some or all of its officers and directors may be residents of a foreign country, that some or all of the experts named in this Prospectus may be, and the underwriters, dealers or agents named in any Prospectus Supplement may be, residents of a foreign country, and a substantial portion of the assets of the Corporation and said persons may be located outside of the United States.

These securities have not been approved or disapproved by the United States Securities and Exchange Commission (the "SEC") nor any state or Canadian securities commission nor has the SEC or any state securities commission passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offence.

Prospective investors should be aware that the acquisition of the Securities described herein may have tax consequences in Canada and the United States. Such consequences may not be described fully herein or in any applicable Prospectus Supplement. Prospective investors should read the tax discussion contained in this Prospectus under the heading "Certain Federal Income Tax Considerations" as well as the tax discussion contained in the applicable Prospectus Supplement with respect to a particular offering of Securities.

The specific terms of the Securities with respect to a particular offering will be set out in the applicable Prospectus Supplement. Where required by statute, regulation or policy, and where Securities are offered in currencies other than Canadian dollars, appropriate disclosure of foreign exchange rates applicable to such Securities will be included in the Prospectus Supplement describing such Securities.

All applicable information permitted under applicable laws to be omitted from this Prospectus that has been omitted will be contained in one or more Prospectus Supplements that will be delivered to purchasers together with this Prospectus. Each Prospectus Supplement will be incorporated by reference into this Prospectus for the purposes of securities legislation as of the date of the Prospectus Supplement and only for the purposes of the distribution of the Securities to which the Prospectus Supplement pertains. Prospective investors should read this Prospectus and any applicable Prospectus Supplement carefully before investing in any Securities issued pursuant to this Prospectus.

No underwriter has been involved in the preparation of this Prospectus or performed any review of the contents of this Prospectus.

This Prospectus constitutes a public offering of these Securities only in those jurisdictions where they may be lawfully offered for sale and therein only by persons permitted to sell such Securities. The Corporation may offer and sell Securities to, or through, underwriters or dealers and may also offer and sell certain Securities directly to other purchasers or through agents pursuant to exemptions from registration or qualification under applicable securities laws. A Prospectus Supplement relating to each issue of Securities offered pursuant to this Prospectus will set forth the names of any underwriters, dealers or agents involved in the offering and sale of such Securities and will set forth the terms of the offering of such Securities, the method of distribution of such Securities including, to the extent applicable, the proceeds to the Corporation, if any, and any fees, discounts or any other compensation payable to underwriters, dealers or agents and any other material terms of the plan of distribution.

In connection with any offering of Securities, except as otherwise set out in a Prospectus Supplement relating to a particular offering of Securities, the underwriters or dealers may over-allot or effect transactions which stabilize or maintain the market price of the 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. However, no underwriter or dealer involved in an "at-the-market distribution", as defined in Canadian National Instrument 44-102 — Shelf Distributions ("NI 44-102"), no affiliate of such an underwriter or dealer and no person or company acting jointly or in concert with such an underwriter or dealer will over-allot Securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Securities. See "Plan of Distribution".

The outstanding Common Shares are listed and posted for trading on the Toronto Stock Exchange (the "TSX") and are listed on the New York Stock Exchange (the "NYSE") under the symbol "SLW". On May 1, 2015, the last trading day prior to the date of this Prospectus, the closing price of the Common Shares on the TSX was C$24.52 and on the NYSE was US$20.17.Unless otherwise specified in the applicable Prospectus Supplement, the Preferred Shares, Debt Securities, Subscription Receipts, Units and Warrants will not be listed on any securities exchange. Consequently, unless otherwise specified in the applicable Prospectus Supplement, there is no market through which the Preferred Shares, Debt Securities, Subscription Receipts, Units and Warrants may be sold and purchasers may not be able to resell any such Securities purchased under this Prospectus. This may affect the pricing of the Preferred Shares, Debt Securities, Subscription Receipts, Units and Warrants in the secondary market, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer regulation.

The Corporation's head office is located at Suite 3150, Park Place, 666 Burrard Street, Vancouver, British Columbia, V6C 2X8 and its registered office is located at Suite 2100, 40 King Street West, Toronto, Ontario, M5H 3C2.

Eduardo Luna, being a director of the Corporation resides outside Canada. Mr. Luna has appointed Cassels Brock & Blackwell LLP, Suite 2100, 40 King Street West, Toronto, Ontario M5H 3L2, as his agent for service of process in Canada. Prospective investors are advised that it may not be possible for investors to enforce judgments obtained in Canada against Mr. Luna, even though he has appointed an agent for service of process.

Investing in the Securities involves significant risks. Prospective purchasers of the Securities should carefully consider the risk factors described under the heading "Risk Factors" and elsewhere in this Prospectus and in documents incorporated by reference in this Prospectus.

All dollar amounts in this Prospectus are in United States dollars, unless otherwise indicated. See "Currency Presentation and Exchange Rate Information".

There can be no assurance that forward — looking statements will prove to be accurate and even if events or results described in the forward-looking statements are realized or substantially realized, there can be no assurance that they will have the expected consequences to, or effects on, the Corporation. Accordingly, readers should not place undue reliance on forward-looking statements and are cautioned that actual outcomes may vary. The forward-looking statements included and incorporated by reference in this Prospectus are for the purpose of providing investors with information to assist them in understanding the Corporation's expected financial and operational performance and may not be appropriate for other purposes.

CAUTIONARY NOTE TO UNITED STATES INVESTORS REGARDING PRESENTATION OF MINERAL
RESERVE AND MINERAL RESOURCE ESTIMATES

This Prospectus, including the documents incorporated by reference herein, has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. The terms "mineral reserve", "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms defined in accordance with Canadian National Instrument 43-101 — Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended. These definitions differ from the definitions in Industry Guide 7 ("SEC Industry Guide 7") under the U.S. Securities Act of 1933, as amended (the "U.S. Securities Act"). Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Also, under SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority.

In addition, the terms "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence and as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures.

Accordingly, information contained in this Prospectus and the documents incorporated by reference herein that describes the Corporation's mineral deposits may not be comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

See "Description of the Business — Technical Information" in the Annual Information Form (as defined herein), which is incorporated by reference herein, for a description of certain of the mining terms used in this Prospectus and the documents incorporated by reference herein.

FINANCIAL INFORMATION

Unless otherwise indicated, all financial information included and incorporated by reference in this Prospectus is determined using IFRS, which differs from United States generally accepted accounting principles.

CURRENCY PRESENTATION AND EXCHANGE RATE INFORMATION

The financial statements of the Corporation incorporated by reference in this Prospectus are reported in United States dollars. All dollar amounts referenced, unless otherwise indicated, are expressed in United States dollars and are referred to as "United States dollars" or "US$". Canadian dollars are referred to as "Canadian dollars" or "C$".

The high, low and closing noon spot rates for Canadian dollars in terms of the United States dollar for each of the two years in the period ended December 31, 2014, as quoted by the Bank of Canada, were as follows:

	Year ended December 31

	2014		2013
High	C$	1.1643	C$	1.0706
Low		1.0614		0.9832
Closing		1.1601		1.0623

THE CORPORATION

General

Silver Wheaton is a mining company which generates its revenue primarily from the sale of silver and gold. To date, the Corporation has entered into 18 long-term purchase agreements and one (1) early deposit long-term purchase agreement associated with silver and/or gold, relating to 28 different mining assets, whereby Silver Wheaton acquires silver and gold production from the counterparties for a per ounce cash payment at or below the prevailing market price. The primary drivers of the Corporation's financial results are the volume of silver and gold production at the various mines and the price of silver and gold realized by Silver Wheaton upon sale.

The Corporation is actively pursuing future growth opportunities, primarily by way of entering into long-term precious metal purchase agreements. There is no assurance, however, that any potential transaction will be successfully completed.

For a further description of the business of the Corporation, see the sections entitled "Corporate Structure" and "Description of the Business" in the Annual Information Form.

The Corporation may, from time to time, during the 25-month period that this Prospectus remains valid, offer for sale and issue Securities. The Corporation may issue and sell up to US$2,000,000,000, in the aggregate, of Securities.

The Corporation may sell the Securities, separately or together, to or through underwriters or dealers, and also may sell Securities to one or more other purchasers directly or through agents. Each Prospectus Supplement will set forth the terms of the offering, including the name or names of any underwriters, dealers or agents and any fees or compensation payable to them in connection with the offering and sale of a particular series or issue of Securities, the public offering price or prices of the Securities and the proceeds to the Corporation from the sale of the Securities.

The 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 negotiated prices, including in transactions that are deemed to be "at-the-market distributions" as defined in NI 44-102, including sales made directly on the TSX, NYSE or other existing trading markets for the Securities. The prices at which the Securities may be offered may vary as between purchasers and during the period of distribution. If, in connection with the offering of Securities at a fixed price or prices, the underwriters have made abona fide effort to sell all of the Securities at the initial offering price fixed in the applicable Prospectus Supplement, the public offering price may be decreased and thereafter further changed, from time to time, to an amount not greater than the initial public offering price fixed in such Prospectus Supplement, in which case the compensation realized by the underwriters will be decreased by the amount that the aggregate price paid by purchasers for the Securities is less than the gross proceeds paid by the underwriters to the Corporation.

Underwriters, dealers and agents who participate in the distribution of the Securities may be entitled under agreements to be entered into with the Corporation to indemnification by the Corporation against certain liabilities, including liabilities under the U.S. Securities Act and Canadian securities legislation, or to contribution 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, the Corporation in the ordinary course of business.

In connection with any offering of Securities, other than an "at-the-market distribution", the underwriters may over-allot or effect transactions which stabilize or maintain the market price of the 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. No underwriter or dealer involved in an "at the market distribution", as defined in NI 44-102, no affiliate of such an underwriter or dealer and no person acting jointly or in concert with such an underwriter or dealer will over allot Securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Securities.

Unless otherwise specified in the applicable Prospectus Supplement, the Corporation does not intend to list any of the Securities other than the Common Shares on any securities exchange. Unless otherwise specified in the applicable Prospectus Supplement, the Preferred Shares, Debt Securities, Subscription Receipts, Units and Warrants will not be listed on any securities exchange. Consequently, unless otherwise specified in the applicable Prospectus Supplement, there is no market through which the Preferred Shares, Debt Securities, Subscription Receipts, Units and Warrants may be sold and purchasers may not be able to resell any such Securities purchased under this Prospectus. This may affect the pricing of the Preferred Shares, Debt Securities, Subscription Receipts, Units and Warrants in the secondary market, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer regulation. No assurances can be given that a market for trading in Securities of any series or issue will develop or as to the liquidity of any such market, whether or not the Securities are listed on a securities exchange.

DESCRIPTION OF SECURITIES

Common Shares

The authorized share capital of the Corporation consists of an unlimited number of Common Shares. As of the date of this Prospectus, there are an aggregate of 403,969,215 Common Shares issued and outstanding. In addition, as of the date of this Prospectus, there were 4,285,300 Common Shares issuable upon the exercise of outstanding stock options, 170,317 Common Shares issuable upon the vesting of restricted share units and 10,000,000 outstanding Warrants. The Common Shares may be offered separately or together with other Securities, as the case may be.

Holders of Common Shares are entitled to receive notice of any meetings of shareholders of the Corporation, to attend and to cast one vote per Common Share at all such meetings. Holders of Common Shares do not have cumulative voting rights with respect to the election of directors and, accordingly, holders of a majority of the Common Shares entitled to vote in any election of directors may elect all directors standing for election. In 2014, the Corporation adopted advance notice provisions for the nomination of directors which apply in circumstances where director nominations are made by shareholders of the Corporation, other than in connection with (i) the requisition of a shareholders' meeting, or (ii) a shareholder proposal, in each case made pursuant to theBusiness Corporations Act (Ontario). The advance notice provisions fix a deadline by which holders of record of Common Shares must submit director nominations to the Corporation prior to any annual or special meeting of shareholders and sets forth the information that a shareholder must include in the notice to the Corporation.

Holders of Common Shares are entitled to receive on a pro rata basis such dividends, if any, as and when declared by the Corporation's Board of Directors at its discretion from funds legally available therefor and upon the liquidation, dissolution or winding up of the Corporation, are entitled to receive on a pro rata basis the net assets of the Corporation after payment of debts and other liabilities, in each case subject to the rights, privileges, restrictions and conditions attaching to any other series or class of shares ranking senior in priority to or on a pro rata basis with the holders of Common Shares with respect to dividends or liquidation. Although the articles of the Corporation provide for the potential issuance of Preferred Shares, there is currently no other series or class of shares outstanding which ranks senior in priority to the Common Shares. The Common Shares do not carry any pre-emptive, subscription, redemption or conversion rights, nor do they contain any sinking or purchase fund provisions. The Common Shares do not carry any provisions permitting or restricting the issuance of additional securities or other material restrictions, nor do they contain any provisions requiring a securityholder to contribute additional capital.

Preferred Shares

The authorized share capital of the Corporation consists of an unlimited number of Preferred Shares. As of the date of this Prospectus, there are nil Preferred Shares issued and outstanding. The Preferred Shares may be offered separately or together with other Securities, as the case may be.

The Preferred Shares may, at any time or from time to time, be issued in one or more series. The Corporation's Board of Directors shall fix before issue, the number of, the consideration per share of, the designation of, and the provisions attaching to the shares of each series. Except as required by law or as otherwise determined by the Corporation's Board of Directors in respect of a series of shares, the holder of a Preferred Share shall not be entitled to vote at meetings of shareholders. The Preferred Shares of each series rank on a priority with the Preferred Shares of every other series and are entitled to preference over the Common Shares and any other shares ranking subordinate to the Preferred Shares with respect to priority and payment of dividends and distribution of assets in the event of liquidation, dissolution or winding-up of the Corporation. The Preferred Shares do not carry any provisions permitting or restricting the issuance of additional securities or other material restrictions, nor do they contain any provisions requiring a securityholder to contribute additional capital.

Debt Securities

In this section describing the Debt Securities, the term "Corporation" refers only to Silver Wheaton Corp. without any of its subsidiaries. The following description sets forth certain general terms and provisions of Debt Securities that may be issued hereunder and is not intended to be complete. The Debt Securities may be offered separately or together with other Securities, as the case may be. The specific terms of Debt Securities, including the extent to which the general terms described in this section apply to those Debt Securities, will be set forth in the applicable Prospectus Supplement.

The Debt Securities will be issued in one or more series under an indenture (the "Indenture") to be entered into between the Corporation and one or more trustees (the "Trustee") that will be named in a Prospectus Supplement for a series of Debt Securities. To the extent applicable, the Indenture will be subject to and governed by theUnited States Trust Indenture Act of 1939, as amended. A copy of the form of the Indenture to be entered into has been filed with the SEC as an exhibit to the registration statement of which this Prospectus forms a part and will be filed with the securities commissions or similar authorities in each of the provinces of Canada when it is entered into. The description of certain provisions of the Indenture in this section do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the provisions of the Indenture. Terms used in this summary that are not otherwise defined herein have the meaning ascribed to them in the Indenture.

The Corporation may issue Debt Securities and incur additional indebtedness other 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 the Corporation may issue under the Indenture and does not limit the amount of other indebtedness that the Corporation may incur. The Indenture provides that the Corporation may issue Debt Securities from time to time in one or more series which may be denominated and payable in United States dollars, Canadian dollars or any other currency. Unless otherwise indicated in the applicable Prospectus Supplement, the Indenture also permits the Corporation, without the consent of the holders of any Debt Securities, to increase the principal amount of any series of Debt Securities the Corporation has previously issued under the Indenture and to issue such increased principal amount.

The particular terms relating to Debt Securities offered by a Prospectus Supplement (the "Offered Securities") will be described in the related Prospectus Supplement. This description may include, but may not be limited to, any of the following, if applicable:

•: the specific designation of the Offered Securities; any limit on the aggregate principal amount of the Offered Securities; the date or dates, if any, on which the Offered Securities will mature and the portion (if less than all of the principal amount) of the Offered Securities to be payable upon declaration of acceleration of maturity;
•: the rate or rates (whether fixed or variable) at which the Offered Securities will bear interest, if any, the date or dates from which any such interest will accrue and on which any such interest will be payable and the record dates for any interest payable on the Offered Securities that are in registered form;
•: the terms and conditions under which the Corporation may be obligated to redeem, repay or purchase the Offered Securities pursuant to any sinking fund or analogous provisions or otherwise;
•: the terms and conditions upon which the Corporation may redeem the Offered Securities, in whole or in part, at its option;
•: the covenants applicable to the Offered Securities;
•: the terms and conditions for any conversion or exchange of the Offered Securities for any other securities;

•: whether the Offered Securities will be issuable in registered form or bearer form or both, and, if issuable in bearer form, the restrictions as to the offer, sale and delivery of the Offered Securities which are in bearer form and as to exchanges between registered form and bearer form;
•: whether the Offered Securities will be issuable in the form of registered global securities ("Global Securities"), and, if so, the identity of the depositary for such registered Global Securities;
•: the denominations in which registered Offered Securities will be issuable, if other than denominations of US$2,000 and integral multiples of US$1,000 and the denominations in which bearer Offered Securities will be issuable, if other than US$5,000;
•: each office or agency where payments on the Offered Securities will be made (if other than the offices or agencies described under the heading "Payment" below) and each office or agency where the Offered Securities may be presented for registration of transfer or exchange;
•: if other than United States dollars, the currency in which the Offered Securities are denominated or the currency in which the Corporation will make payments on the Offered Securities;
•: any index, formula or other method used to determine the amount of payments of principal of (and premium, if any) or interest, if any, on the Offered Securities; and
•: any other terms of the Offered Securities which apply solely to the Offered Securities, or terms described herein as generally applicable to the Debt Securities which are not to apply to the Offered Securities.

Unless otherwise indicated in the applicable Prospectus Supplement:

•: holders may not tender Debt Securities to the Corporation for repurchase; and

the rate or rates of interest on the Debt Securities will not increase if the Corporation becomes involved in a highly leveraged transaction or the Corporation is acquired by another entity.The Corporation may issue Debt Securities under the Indenture bearing no interest or interest at a rate below the prevailing market rate at the time of issuance and, in such circumstances, the Corporation may offer and sell those Debt Securities at a discount below their stated principal amount. The Corporation will describe in the applicable Prospectus Supplement any Canadian and U.S. federal income tax consequences and other special considerations applicable to any 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 U.S. federal income tax purposes.

Any Debt Securities issued by the Corporation will be direct, unconditional and unsecured obligations of the Corporation and will rank equally among themselves and with all of the Corporation's other unsecured, unsubordinated obligations, except to the extent prescribed by law. Debt Securities issued by the Corporation will be structurally subordinated to all existing and future liabilities, including trade payables and other indebtedness, of the Corporation's subsidiaries. The Corporation will agree to provide to the Trustee (i) annual reports containing audited financial statements and (ii) quarterly reports for the first three quarters of each fiscal year containing unaudited financial information.

Form, Denomination, Exchange and Transfer

Unless otherwise indicated in the applicable Prospectus Supplement, the Corporation will issue Debt Securities only in fully registered form without coupons, and in denominations of US$2,000 and integral multiples of US$1,000. Debt Securities may be presented for exchange and registered Debt Securities may be presented for registration of transfer in the manner to be set forth in the Indenture and in the applicable Prospectus Supplement, without service charges. The Corporation may, however, require payment sufficient to cover any taxes or other governmental charges due in connection with the exchange or transfer. The Corporation will appoint the Trustee as security registrar. Bearer Debt Securities and the coupons applicable to bearer Debt Securities thereto will be transferable by delivery.

Payment

Unless otherwise indicated in the applicable Prospectus Supplement, the Corporation will make payments on registered Debt Securities (other than Global Securities) at the office or agency of the Trustee, except that

the Corporation may choose to pay interest (a) by check mailed to the address of the person entitled to such payment as specified in the security register, or (b) by wire transfer to an account maintained by the person entitled to such payment as specified in the security register. Unless otherwise indicated in the applicable Prospectus Supplement, the Corporation will pay any interest due on registered Debt Securities to the persons in whose name such registered Securities are registered on the day or days specified in the applicable Prospectus Supplement.

Registered Global Securities

Unless otherwise indicated in the applicable Prospectus Supplement, registered Debt Securities of a series will be issued in global form that will be deposited with, or on behalf of, a depositary (the "Depositary") identified in the Prospectus Supplement. Global Securities will be registered in the name of the Depositary, and the Debt Securities included in the Global Securities may not be transferred to the name of any other direct holder unless the special circumstances described below occur. Any person wishing to own Debt Securities issued in the form of Global Securities must do so indirectly by virtue of an account with a broker, bank or other financial institution that, in turn, has an account with the Depositary.

Special Investor Considerations for Global Securities

The Corporation's obligations under the Indenture, as well as the obligations of the Trustee and those of any third parties employed by the Corporation or the Trustee, run only to persons who are registered as holders of Debt Securities. For example, once the Corporation makes payment to the registered holder, the Corporation has no further responsibility for the payment even if that holder is legally required to pass the payment along to an investor but does not do so. As an indirect holder, an investor's rights relating to a Global Security will be governed by the account rules of the investor's financial institution and of the Depositary, as well as general laws relating to debt securities transfers.

An investor should be aware that when Debt Securities are issued in the form of Global Securities:

•: the investor cannot have Debt Securities registered in his or her own name;
•: the investor cannot receive physical certificates for his or her interest in the Debt Securities;
•: the investor must look to his or her own bank, brokerage firm or other financial institution for payments on the Debt Securities and protection of his or her legal rights relating to the Debt Securities;
•: the investor may not be able to sell interests in the Debt Securities to some insurance companies and other institutions that are required by law to hold the physical certificates of Debt Securities that they own;
•: the Depositary's policies will govern payments, transfers, exchange and other matters relating to the investor's interest in the Global Security; the Corporation and the Trustee will have no responsibility for any aspect of the Depositary's actions or for its records of ownership interests in the Global Security; the Corporation and the Trustee also do not supervise the Depositary in any way; and
•: the Depositary will usually require that interests in a Global Security be purchased or sold within its system using same-day funds.

Special Situations When Global Security Will be Terminated

In a few special situations described below, a Global Security will terminate and interests in it will be exchanged for physical certificates representing Debt Securities. After that exchange, an investor may choose whether to hold Debt Securities directly or indirectly through an account at its bank, brokerage firm or other financial institution. Investors must consult their own banks, brokers or other financial institutions to find out how to have their interests in Debt Securities transferred into their own names, so that they will be registered holders of the Debt Securities represented by each Global Security.

The special situations for termination of a Global Security are:

•: when the Depositary notifies the Corporation that it is unwilling, unable or no longer qualified to continue as Depositary (unless a replacement Depositary is named); and
•: when and if the Corporation decides to terminate a Global Security.

The Prospectus Supplement may list situations for terminating a Global Security that would apply only to the particular series of Debt Securities covered by the Prospectus Supplement. When a Global Security terminates, the Depositary (and not the Corporation or the Trustee) will be responsible for deciding the names of the institutions that will be the initial direct holders.

Events of Default

Unless otherwise indicated in the applicable Prospectus Supplement, the term "Event of Default" with respect to Debt Securities of any series means any of the following:

(a): default in the payment of the principal of (or any premium on) any Debt Security of that series at its Maturity;
(b): default in the payment of any interest on any Debt Security of that series when it becomes due and payable, and continuance of such default for a period of 30 days;
(c): default in the deposit of any sinking fund payment, when the same becomes due by the terms of the Debt Securities of that series;
(d): default in the performance, or breach, of any other covenant or agreement of the Corporation in the Indenture in respect of the Debt Securities of that series (other than a covenant or agreement for which default or breach is specifically dealt with elsewhere in the Indenture), where such default or breach continues for a period of 90 days after written notice thereof to the Corporation by the Trustee or the holders of at least 25 per cent in principal amount of all outstanding Debt Securities affected thereby;
(e): certain events of bankruptcy, insolvency or reorganization; or
(f): any other event of default provided with respect to the Debt Securities of that series.

If an Event of Default occurs and is continuing with respect to Debt Securities of any series, then the Trustee or the holders of not less than 25 per cent in principal amount of the outstanding Debt Securities of that series may require the principal amount (or, if the Debt Securities of that series are Original Issue Discount Securities or Indexed Securities, such portion of the principal amount as may be specified in the terms of that series) of all the outstanding Debt Securities of that series and any accrued but unpaid interest on such Debt Securities be paid immediately. However, at any time after a declaration of acceleration with respect to Debt Securities of any series or all series affected (or of all series, as the case may be) has been made and before a judgment or decree for payment of the money due has been obtained, the holders of a majority in principal amount of the outstanding Debt Securities of such series or of all series affected (or of all series, as the case may be), by written notice to the Corporation and the Trustee, may, under certain circumstances, rescind and annul such acceleration. The applicable Prospectus Supplement will contain provisions relating to acceleration of the maturity of a portion of the principal amount of Original Issue Discount Securities or Indexed Securities upon the occurrence of any Event of Default and the continuation thereof.

Other than its duties in the case of an Event of Default, the Trustee will not be obligated to exercise any of its rights and powers under the Indenture at the request or direction of any of the holders, unless the holders have offered to the Trustee reasonable indemnity. If the holders provide reasonable indemnity, the holders of a majority in principal amount of the outstanding Debt Securities of all series affected by an Event of Default may, subject to certain limitations, direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Debt Securities of all series affected by such Event of Default.

No holder of a Debt Security of any series will have any right to institute any proceedings, judicial or otherwise, unless:

•: such holder has previously given to the Trustee written notice of a continuing Event of Default with respect to the Debt Securities of that series;
•: the holders of at least 25 per cent in principal amount of the outstanding Debt Securities of all series affected by such Event of Default have made written request and have offered reasonable indemnity to the Trustee to institute such proceedings as trustee; and
•: the Trustee has failed to institute such proceeding, and has not received from the holders of a majority in the aggregate principal amount of outstanding Debt Securities of all series affected by such Event of Default a direction inconsistent with such request, within 60 days after such notice, request and offer.

However, these limitations do not apply to a suit instituted by the holder of a Debt Security for the enforcement of payment of principal of or interest on such Debt Security on or after the applicable due date of such payment.

The Corporation will be required to furnish to the Trustee annually an officers' certificate as to the performance of certain of its obligations under the Indenture and as to any default in such performance.

Defeasance

In this section, the term "defeasance" means discharge from some or all of the Corporation's obligations under the Indenture with respect to Debt Securities of a particular series. Unless otherwise stated in the applicable Prospectus Supplement, if the Corporation deposits with the Trustee sufficient cash or government securities to pay the principal, interest, any premium and any other sums due to the stated maturity or a redemption date of the Debt Securities of a particular series, then at its option:

•: the Corporation will be discharged from its obligations with respect to the Debt Securities of such series with certain exceptions, and the holders of the Debt Securities of the affected series will not be entitled to the benefits of the Indenture except for registration of transfer and exchange of Debt Securities and replacement of lost, stolen or mutilated Debt Securities and certain other limited rights. Such holders may look only to such deposited funds or obligations for payment; or
•: the Corporation will no longer be under any obligation to comply with certain covenants under the Indenture, and certain Events of Default will no longer apply to it.

Unless otherwise stated in the applicable Prospectus Supplement, to exercise defeasance the Corporation also must deliver to the Trustee:

•: an opinion of U.S. counsel to the effect that the deposit and related defeasance would not cause the holders of the Debt Securities of the applicable series to recognize income, gain or loss for U.S. federal income tax purposes and that holders of the Debt Securities of that series 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; and
•: an opinion of Canadian counsel or a ruling from Canada Revenue Agency that there would be no such recognition of income, gain or loss for Canadian federal or provincial income tax purposes and that holders of the Debt Securities of that series will be subject to Canadian federal and provincial 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.

In addition, no Event of Default with respect to the Debt Securities of the applicable series can have occurred and the Corporation cannot be an insolvent person under theBankruptcy and Insolvency Act (Canada). In order for U.S. counsel to deliver the opinion that would allow the Corporation to be discharged from all of its obligations under the Debt Securities of any series, the Corporation must have received from, or there must have been published by, the Internal Revenue Service a ruling, or there must have been a change in law so that the deposit and defeasance would not cause holders of the Debt Securities of such series to recognize income, gain or loss for U.S. federal income tax purposes and so that such holders would 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.

Modifications and Waivers

The Corporation may modify or amend the Indenture with the consent of the holders of a majority in aggregate principal amount of the outstanding Debt Securities of all series affected by such modification or amendment; provided, however, unless otherwise stated in the applicable Prospectus Supplement, that the Corporation will be required to receive consent from the holder of each outstanding Debt Security of such affected series to:

•: change the stated maturity of the principal of, or interest on, such outstanding Debt Security;
•: reduce the principal amount of or interest on such outstanding Debt Security;
•: reduce the amount of the principal payable upon the acceleration of the maturity of an outstanding Original Issue Discount Security;
•: change the place or currency of payments on such outstanding Debt Security;
•: reduce the percentage in principal amount of outstanding Debt Securities of such series, from which the consent of holders is required to modify or amend the Indenture or waive compliance with certain provisions of the Indenture or waive certain defaults; or
•: modify any provisions of the Indenture relating to modifying or amending the Indenture or waiving past defaults or covenants except as otherwise specified.

The holders of a majority in principal amount of Debt Securities of any series or of the affected series may waive the Corporation's compliance with certain restrictive provisions of the Indenture with respect to such series. The holders of a majority in principal amount of outstanding Debt Securities of all series with respect to which an Event of Default has occurred may waive any past default under the Indenture, except a default in the payment of the principal of or interest on any Debt Security or in respect of any item listed above.

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 does not adversely affect the interests of any holder of such Debt Securities.

Consent to Jurisdiction and Service

Under the Indenture, the Corporation will irrevocably appoint an authorized agent upon which process may be served in any suit, action or proceeding arising out of or relating to the Offered Securities or the Indenture that may be instituted in any United States federal or New York state court located in The City of New York, and will submit to such non-exclusive jurisdiction.

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.

Enforceability of Judgments

Since a substantial portion of the assets of the Corporation are outside the United States, any judgment obtained in the United States against the Corporation may need to be satisfied by seeking enforcement of such judgment in a court located outside of the United States from the Corporation's assets. The Corporation has been advised by its Canadian counsel, Cassels Brock & Blackwell LLP, that there is doubt as to the enforceability in Canada by a court in original actions, or in actions to enforce judgments of United States courts, of civil liabilities predicated upon United States federal securities laws.

The Trustee

The Trustee under the Indenture or its affiliates may provide banking and other services to the Corporation in the ordinary course of their business.

The Indenture will contain certain limitations on the rights of the Trustee, as long as it or any of its affiliates remains the Corporation's creditor, to obtain payment of claims in certain cases or to realize on certain property received on any claim as security or otherwise. The Trustee and its affiliates will be permitted to engage in other transactions with the Corporation. If the Trustee or any affiliate acquires any conflicting interest and a default occurs with respect to the Debt Securities, the Trustee must eliminate the conflict or resign.

Subscription Receipts

The following description sets forth certain general terms and provisions of Subscription Receipts that may be issued hereunder and is not intended to be complete. Subscription Receipts may be issued at various times which will entitle holders thereof to receive, upon satisfaction of certain release conditions and for no additional consideration, Common Shares, Debt Securities, Warrants, Units or any combination thereof. The Subscription Receipts may be offered separately or together with other Securities, as the case may be. Subscription Receipts will be issued pursuant to one or more subscription receipt agreements (each, a "Subscription Receipt Agreement"), each to be entered into between the Corporation and an escrow agent (the "Escrow Agent") that will be named in the relevant Prospectus Supplement. Each Escrow Agent will be a financial institution organized under the laws of Canada or a province thereof and authorized to carry on business as a trustee. If underwriters or agents are used in the sale of any Subscription Receipts, one or more of such underwriters or agents may also be a party to the Subscription Receipt Agreement governing the subscription receipts sold to or through such underwriter or agent.

The statements made in this Prospectus relating to any Subscription Receipt Agreement and Subscription Receipts to be issued under this Prospectus are summaries of certain anticipated provisions thereof and do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the provisions of the applicable Subscription Receipt Agreement. You should refer to the Subscription Receipt Agreement relating to the specific Subscription Receipts being offered for the complete terms of the Subscription Receipts. A copy of any Subscription Receipt Agreement relating to an offering or Subscription Receipts will be filed by the Corporation with the securities regulatory authorities in applicable Canadian offering jurisdictions and the United States after the Corporation has entered into it.

The particular terms of each issue of Subscription Receipts will be described in the related Prospectus Supplement. This description may include, but may not be limited to, any of the following, if applicable:

•: the designation and aggregate number of such Subscription Receipts being offered;
•: the price at which such Subscription Receipts will be offered;
•: the designation, number and terms of the Common Shares, Debt Securities, Warrants, Units or any combination thereof to be received by the holders of such Subscription Receipts upon satisfaction of the release conditions, and any procedures that will result in the adjustment of those numbers;
•: the conditions (the "Release Conditions") that must be met in order for holders of such Subscription Receipts to receive, for no additional consideration, Common Shares, Debt Securities, Warrants, Units or any combination thereof;
•: the procedures for the issuance and delivery of the Common Shares, Debt Securities, Warrants, Units or any combination thereof to holders of such Subscription Receipts upon satisfaction of the Release Conditions;

•: the terms and conditions under which the Escrow Agent will release all or a portion of the Escrowed Funds to the Corporation upon satisfaction of the Release Conditions and if the Subscription Receipts are sold to or through underwriters or agents, the terms and conditions under which the Escrow Agent will release a portion of the Escrowed Funds to such underwriters or agents in payment of all or a portion of their fees or commissions in connection with the sale of the Subscription Receipts;
•: procedures for the refund by the Escrow Agent to holders of such Subscription Receipts of all or a portion of the subscription price of their Subscription Receipts, plus any pro rata entitlement to interest earned or income generated on such amount, if the Release Conditions are not satisfied;
•: any contractual right of rescission to be granted to initial purchasers of such Subscription Receipts in the event that this Prospectus, the Prospectus Supplement under which Subscription Receipts are issued or any amendment hereto or thereto contains a misrepresentation;
•: any entitlement of the Corporation to purchase such Subscription Receipts in the open market by private agreement or otherwise;
•: if the Subscription Receipts are issued as a Unit with another Security, the date, if any, on and after which the Subscription Receipts and the other Security will be separately transferable;
•: whether the Corporation will issue such Subscription Receipts as global securities and, if so, the identity of the depository for the global securities;
•: whether the Corporation will issue such Subscription Receipts as bearer securities, as registered securities or both;
•: provisions as to modification, amendment or variation of the Subscription Receipt Agreement or any rights or terms of such Subscription Receipts, including upon any subdivision, consolidation, reclassification or other material change of the Common Shares, Debt Securities, Warrants, Units or other securities, any other reorganization, amalgamation, merger or sale of all or substantially all of the Corporation's assets or any distribution of property or rights to all or substantially all of the holders of Common Shares;
•: whether the Corporation will apply to list such Subscription Receipts on any exchange;
•: material United States and Canadian federal income tax consequences of owning such Subscription Receipts; and
•: any other material terms or conditions of such Subscription Receipts.

Rights of Holders of Subscription Receipts Prior to Satisfaction of Release Conditions

The holders of Subscription Receipts will not be, and will not have the rights of, shareholders of the Company. Holders of Subscription Receipts are entitled only to receive Common Shares, Debt Securities, Warrants, Units or a combination thereof on exchange or conversion of their Subscription Receipts, plus any cash payments, all as provided for under the Subscription Receipt Agreement and only once the Release Conditions have been satisfied.

Escrow

The Subscription Receipt Agreement will provide that the Escrowed Funds will be held in escrow by the Escrow Agent, and such Escrowed Funds will be released to the Company (and, if the Subscription Receipts are sold to or through underwriters or agents, a portion of the Escrowed Funds may be released to such underwriters or agents in payment of all or a portion of their fees in connection with the sale of the Subscription Receipts) at the time and under the terms specified by the Subscription Receipt Agreement. If the Release Conditions are not satisfied, holders of Subscription Receipts will receive a refund of all or a portion of the

subscription price for their Subscription Receipts, plus their pro-rata entitlement to interest earned or income generated on such amount, if provided for in the Subscription Receipt Agreement, in accordance with the terms of the Subscription Receipt Agreement.

Modifications

The Subscription Receipt Agreement will specify the terms upon which modifications and alterations to the Subscription Receipts issued thereunder may be made by way of a resolution of holders of Subscription Receipts at a meeting of such holders or consent in writing from such holders. The number of holders of Subscription Receipts required to pass such a resolution or execute such a written consent will be specified in the Subscription Receipt Agreement.

Units

The following description sets forth certain general terms and provisions of the Units that may be issued hereunder and is not intended to be complete. Units may be issued at various times comprising any combination of the other Securities described in this Prospectus. Each Unit will be issued so that the holder of such Unit is also the holder of each Security composing such Unit. Therefore, the holder of a Unit will have the rights and obligations of a holder of each included Security (except in some cases where the right to transfer an included Security of a Unit may not occur without the transfer of the other included security comprising part of such Unit). The Units may be offered separately or together with other Securities, as the case may be.

The particular terms of each issue of Units will be described in the related Prospectus Supplement. This description may include, but may not be limited to, any of the following, if applicable:

•: the designation and aggregate number of Units;
•: the price at which the Units will be offered;
•: the designation and terms of the Units and the Securities comprising the Units, including whether and under what circumstances those Securities may be held or transferred separately;
•: any provisions for the issuance, payment, settlement, transfer or exchange of the Units or of the Securities comprising the units;
•: whether the Corporation will apply to list the Units on any exchange;
•: the material United States and Canadian Federal income tax consequences of owning the Units, including how the purchase price paid will be allocated among the Securities comprising the Units; and
•: whether the Units will be issued in fully registered or global form.

Warrants

The following description sets forth certain general terms and provisions of Warrants for the purchase of Common Shares, Preferred Shares, Units or Debt Securities that may be issued hereunder and is not intended to be complete. The Warrants may be offered separately or together with other Securities, as the case may be. Warrants may be issued at various times under one or more warrant indenture to be entered into by the Corporation and one or more banks or trust companies acting as warrant agent.

The statements made in this Prospectus relating to any warrant indenture and Warrants to be issued under this Prospectus are summaries of certain anticipated provisions thereof and do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the provisions of the applicable warrant indenture. You should refer to the warrant indenture relating to the specific Warrants being offered for the

complete terms of the Warrants. A copy of any warrant indenture relating to an offering or Warrants will be filed by the Corporation with the securities regulatory authorities in applicable Canadian offering jurisdictions and the United States after the Corporation has entered into it.

The particular terms of each issue of Warrants will be described in the related Prospectus Supplement. This description may include, but may not be limited to, any of the following, if applicable:

•: the designation and aggregate number of Warrants;
•: the price at which the Warrants will be offered;
•: the designation, number and terms of the Common Shares, Preferred Shares, Units or Debt Securities, as applicable, purchasable upon exercise of the Warrants, and procedures that will result in the adjustment of those numbers;
•: the date on which the right to exercise the Warrants will commence and the date on which the right will expire;
•: the exercise price of the Warrants;
•: if the Warrants are issued as a Unit with another Security, the date, if any, on and after which the Warrants and the other Security will be separately transferable;
•: any minimum or maximum amount of Warrants that may be exercised at any one time;
•: any terms, procedures and limitations relating to the transferability, exchange or exercise of the Warrants;
•: whether the Warrants will be subject to redemption or call and, if so, the terms of such redemption or call provisions;
•: provisions as to modification, amendment or variation of the warrant indenture or any rights or terms of such Warrants, including upon any subdivision, consolidation, reclassification or other material change of the Common Shares, Preferred Shares, Units, Debt Securities or other securities, any other reorganization, amalgamation, merger or sale of all or substantially all of the Corporation's assets or any distribution of property or rights to all or substantially all of the holders of Common Shares;
•: material United States and Canadian federal income tax consequences of owning the Warrants; and
•: any other material terms or conditions of the Warrants.

Warrant certificates will be exchangeable for new Warrant certificates of different denominations at the office indicated in the Prospectus Supplement. Prior to the exercise of their Warrants, holders of Warrants will not have any of the rights of holders of the securities subject to the Warrants. The Corporation may amend the warrant indenture(s) and the Warrants, without the consent of the holders of the Warrants, to cure any ambiguity, to cure, correct or supplement any defective or inconsistent provision or in any other manner that will not prejudice the rights of the holders of outstanding Warrants, as a group.

CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

The applicable Prospectus Supplement may describe certain Canadian federal income tax consequences to an investor who is a non-resident of Canada or to an investor who is a resident of Canada of acquiring, owning and disposing of any of the Securities offered thereunder.

INTERESTS OF EXPERTS

The scientific and technical information for the Corporation's mineral projects on a property material to the Company contained in the Annual Information Form, other than for the Salobo mine, was sourced by the Corporation from the following SEDAR (www.sedar.com) and EDGAR (www.sec.gov) filed documents:

b.: San Dimas mine — Primero Mining Corp's ("Primero") MD&A and Primero's annual information form filed on March 31, 2015; and

A summary of the information sourced from the annual information forms of each of Primero, Goldcorp and Barrick is contained in the Annual Information Form under "Technical Information — Further Disclosure Regarding Mineral Projects on Material Properties — San Dimas Mine, Mexico," "Technical Information — Further Disclosure Regarding Mineral Projects on Material Properties — Peñasquito Mine, Mexico," "Technical Information — Further Disclosure Regarding Mineral Projects on Material Properties — Pascua-Lama Project, Border of Chile and Argentina", respectively. A summary of the information sourced from the annual financial statements and/or the management's discussion and analysis for each of Primero, Goldcorp and Barrick, as the case may be, is contained in the Annual Information Form under "General Development of the Business" and "Description of the Business". Neil Burns, M.Sc., P.Geo., Vice President, Technical Services, and Samuel Mah, M.A.Sc., P.Eng., Senior Director, Project Evaluations, are the qualified persons as defined by NI 43-101 in connection with the mineral reserve and mineral resource estimates and the scientific and technical information, and have reviewed and approved the disclosure, for the San Dimas mine, the Peñasquito mine and the Pascua-Lama project contained in the Annual Information Form.

Christopher Jacobs, CEng MIMMM, Vice President and Mining Economist, Micon International Ltd., James Turner, CEng MIMMM, Senior Mineral Process Engineer, Micon International Ltd., Barnard Foo, P. Eng., M. Eng., MBA, Senior Mining Engineer, Micon International Ltd. and Jason Ché Osmond, FGS, C.Geol, EurGeol, Senior Geologist, Micon International Ltd. prepared a technical report in accordance with NI 43-101 entitled "Technical Report on the Mineral Reserves and Mineral Resources of the Salobo Copper-Gold Mine Carajás, Pará State, Brazil" dated March 19, 2013 (the "Salobo Report") and have reviewed and approved the disclosure concerning the Salobo mine contained in the Annual Information Form, which for greater certainty includes disclosure regarding forecasted production from the Salobo mine attributable to Silver Wheaton. A copy of the Salobo Report is available under Silver Wheaton's profile on SEDAR at www.sedar.com and on EDGAR at (www.sec.gov) and a summary of the Salobo Report is contained in the Annual Information Form under the heading "Technical Information — Further Disclosure Regarding Mineral Projects on Material Properties — Salobo Mine, Brazil".

The aforementioned firms or persons held no securities or other property of the Corporation or of any associate or affiliate of the Corporation when they prepared the reports, the mineral reserve estimates or the mineral resource estimates referred to above, or following the preparation of such reports or estimates and did not, and will not, receive any direct or indirect interest in any securities or other property of the Corporation or of any associate or affiliate of the Corporation in connection with the preparation of such reports or estimates, other than Neil Burns and Samuel Mah, who together hold less than 1% of the Common Shares. None of the aforementioned persons are currently expected to be elected, appointed or employed as a director, officer or employee of the Corporation or of any associate or affiliate of the Corporation, other than Neil Burns and Samuel Mah who are employees of the Corporation.

Deloitte LLP is the auditor of the Corporation and is independent of the Corporation within the meaning of the Rules of Professional Conduct of the Institute of Chartered Accountants of British Columbia and the rules and standards of the United States Public Company Accounting Oversight Board and the securities laws and regulations administered by the SEC.

LEGAL MATTERS

Certain legal matters in connection with the Offering will be passed upon on behalf of the Corporation by Cassels Brock & Blackwell LLP, as to Canadian legal matters, and Paul, Weiss, Rifkind, Wharton & Garrison LLP, as to United States legal matters. As of the date hereof, the partners and associates of Cassels Brock & Blackwell own, directly or indirectly, less than 1% of the Common Shares.

ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES

The Corporation is an Ontario corporation and its principal place of business is in Canada. The majority of the directors and officers of the Corporation are resident outside of the United States and a substantial portion of its assets and the assets of such persons are located outside of the United States. Consequently, it may be difficult for United States investors to effect service of process within the United States on the Corporation or its directors or officers, or to realize in the United States on judgments of courts of the United States predicated on civil liabilities under the U.S. Securities Act. Investors should not assume that Canadian courts would enforce judgments of United States courts obtained in actions against the Corporation or such persons predicated on the civil liability provisions of the United States federal securities laws or the securities or "blue sky" laws of any state within the United States or would enforce, in original actions, liabilities against the Corporation or such persons predicated on the United States federal securities or any such state securities or "blue sky" laws. The Corporation has been advised by its Canadian counsel, Cassels Brock & Blackwell LLP, that a judgment of a United States court predicated solely upon civil liability under United States federal securities laws would probably be enforceable in Canada if the United States court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes. The Corporation has also been advised by Cassels Brock & Blackwell LLP, however, that there is substantial doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon United States federal securities laws.

The Corporation filed with the SEC, concurrently with the Registration Statement on Form F-10 of which this prospectus is a part, an appointment of agent for service of process on Form F-X. Under the Form F-X, the Corporation appointed Puglisi & Associates as its agent for service of process in the United States in connection with any investigation or administrative proceeding conducted by the SEC, and any civil suit or action brought against or involving the Corporation in a United States court, arising out of or related to or concerning the offering of Securities under this Prospectus.

Limitation

(3) A corporation shall not indemnify an individual under subsection (1) unless the individual acted honestly and in good faith with a view to the best interests of the corporation 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 corporation's request.

Same

(4) In addition to the conditions set out in subsection (3), if the matter is a criminal or administrative action or proceeding that is enforced by a monetary penalty, the corporation shall not indemnify an individual under subsection (1) unless the individual had reasonable grounds for believing that the individual's conduct was lawful.

Derivative Actions

(4.1) A corporation may, with the approval of a court, indemnify an individual referred to in subsection (1), or advance moneys under subsection (2), in respect of an action by or on behalf of the corporation or other entity to obtain a judgment in its favour, to which the individual is made a party because of the individual's association with the corporation or other entity as described in subsection (1), against all costs, charges and expenses reasonably incurred by the individual in connection with such action, if the individual fulfils the conditions set out in subsection (3).

Right to Indemnity

(4.2) Despite subsection (1), an individual referred to in that subsection is entitled to indemnity from the corporation in respect of all costs, charges and expenses reasonably incurred by the individual in connection with the defence of any civil, criminal, administrative, investigative or other proceeding to

Insurance

(4.3) A corporation may purchase and maintain insurance for the benefit of an individual referred to in subsection (1) against any liability incurred by the individual,

(a): in the individual's capacity as a director or officer of the corporation; or
(b): in the individual's capacity as a director or officer, or a similar capacity, of another entity, if the individual acts or acted in that capacity at the corporation's request.

Application to Court

(5) A corporation or a person referred to in subsection (1) may apply to the court for an order approving an indemnity under this section and the court may so order and make any further order it thinks fit.

Idem

(6) Upon an application under subsection (5), the court may order notice to be given to any interested person and such person is entitled to appear and be heard in person or by counsel.

Article 6 of By-Law No. 2 of the Corporation provides as follows:

Protection of Directors, Officers and Others

6.03 Limitation of Liability. Except as otherwise provided in the OBCA, no director or officer for the time being of the Corporation shall be liable for the acts, receipts, neglects or defaults of any other director or officer or employee or for joining in any receipt or act for conformity or for any loss, damage or expense happening to the Corporation through the insufficiency or deficiency of title to any property acquired by the Corporation or for or on behalf of the Corporation or for the insufficiency or deficiency of any security in or upon which any of the moneys of or belonging to the Corporation shall be placed out or invested or for any loss or damage arising from the bankruptcy, insolvency or tortious act of any persons, firm or corporation including any person, firm or corporation with whom or which any moneys, securities or effects shall be lodged or deposited for any loss, conversion, misapplication or misappropriation of or any damage resulting from any dealings with any moneys, securities or other assets belonging to the Corporation or for any other loss, damage or misfortune whatever which may happen in the execution of the duties of his respective office or trust or in relation thereto unless the same shall happen by or through his failure to exercise the powers and to discharge the duties of his office honestly, in good faith and in the best interests of the Corporation and in connection therewith to exercise the degree of care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. The directors for the time being of the Corporation shall not be under any duty or responsibility in respect of any contract, act or transaction whether or not made, done or entered into in the name or on behalf of the Corporation, except such as shall have been submitted to and authorized or approved by the board. If any director or officer of the Corporation shall be employed by or shall perform services for the Corporation otherwise than as a director or officer or shall be a member of a firm or a shareholder, director or officer of a company which is employed by or performs services for the Corporation, the fact of his being a director or officer of the Corporation

II-2

shall not disentitle such director or officer or such firm or company, as the case may be, from receiving proper remuneration for such services.

6.04 Indemnity. Subject to the limitations contained in the OBCA, the Corporation shall indemnify a director or officer, a former director or officer, or another individual who acts or acted at the Corporation'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 Corporation or other entity, if

(b): 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 individual's conduct was lawful; and
(c): a court or other competent authority has not judged that the individual has committed any fault or omitted to do anything that the individual ought to have done.

The Corporation shall also indemnify such person in such other circumstances as the OBCA permits or requires.

Section 6.05Insurance: The Corporation may purchase and maintain insurance for the benefit of any person referred to in Section 6.04 against such liabilities and in such amounts as the board may from time to time determine and are permitted by the OBCA.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, 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 Act and is therefore unenforceable.
