               5.25% CONVERTIBLE UNSECURED SENIOR SUBORDINATED DEBENTURES


This prospectus supplement is being filed in respect of the offering (the
"Offering") of US$75,000,000 convertible unsecured senior subordinated
debentures (the "Debentures") of Pan American Silver Corp. (the "Company"). The
Debentures offered hereby will mature on July 31, 2009 and will bear interest at
a rate per annum of 5.25%. Interest on the Debentures is payable semi-annually
on January 31 and July 31 in each year commencing on January 31, 2004. The
Debentures will be issued and sold in denominations of US$1,000 and integral
multiples thereof. On or after July 31, 2006, the Debentures may be redeemed in
whole or in part by the Company, at its option on not more than 60 and not less
than 30 days prior notice and subject to regulatory approval, at a price equal
to par, plus accrued and unpaid interest, if any, provided that the weighted
average trading price of the common shares in the capital of the Company (the
"Common Shares") on the Nasdaq National Market ("NASDAQ") for the 20 consecutive
trading days ending five trading days preceding the date of the redemption
notice equals at least 125% of the conversion price, which is initially US$9.57.
On redemption or upon maturity, provided that no default or event of default has
occurred and is continuing, the Company may, at its option, on not more than 60
and not less than 30 days prior notice and subject to regulatory approval, elect
to satisfy its obligation to repay the principal amount of the Debentures by
issuing and delivering that number of freely tradable Common Shares obtained by
dividing the principal amount of the outstanding Debentures which are to be
redeemed or have matured, as the case may be, by 95% of the weighted average
trading price of the Common Shares on NASDAQ for the 20 consecutive trading days
ending five trading days preceding the date fixed for redemption or maturity, as
the case may be. The Debentures will rank subordinate to all current and future
Senior Indebtedness (as defined herein) and will rank at least PARI PASSU with
all other unsecured indebtedness. The Company has agreed that neither it nor its
subsidiaries will issue, by public offering or private placement, any unsecured
bonds, debentures, notes or other capital markets debt instruments unless all
such debt is, by its terms, subordinate to the Debentures. See "Description of
the Debentures -- Subordination".

                                                        CONVERSION PRIVILEGE
  Each US$1,000 principal amount of Debentures will be convertible into Common
  Shares at the option of the holder at any time prior to the earlier of the
  close of business on July 31, 2009 and the last business day immediately
  preceding any date fixed for redemption, into 104.4932 Common Shares
  (subject to adjustment in certain events), representing a conversion price
  of US$9.57.

The closing price of the Common Shares on July 22, 2003 on the Toronto Stock
Exchange (the "TSX") was Cdn.$10.48 per Common Share and on NASDAQ was $7.41 per
Common Share. The TSX has conditionally approved the listing of the Debentures
and the listing of the Common Shares issuable upon conversion of the Debentures.
The Company has notified NASDAQ of the proposed issuance of the Debentures and
the Common Shares issuable upon conversion of the Debentures. There is no
current intention to list the Debentures on NASDAQ. The price for this Offering
was determined by negotiation between the Company and BMO Nesbitt Burns Inc.,
CIBC World Markets Inc. and Canaccord Capital Corporation (collectively, the
"Underwriters").

THE EARNINGS COVERAGE RATIOS OF THE COMPANY FOR THE FISCAL YEAR ENDED
DECEMBER 31, 2002 AND THE 12-MONTH PERIOD ENDED MARCH 31, 2003 ARE EACH LESS
THAN ONE-TO-ONE. SEE "PRO FORMA EARNINGS COVERAGE".

AN INVESTMENT IN THE DEBENTURES IS SUBJECT TO A NUMBER OF RISKS THAT SHOULD BE
CONSIDERED BY A PROSPECTIVE PURCHASER. SEE "RISK FACTORS".

               SPECIAL NOTE REGARDING FORWARD-LOOKING INFORMATION

    Some of the statements included or incorporated by reference in this

of the United States Private Securities Litigation Reform Act of 1995. When used
herein, the words "anticipate", "believe", "estimate", "expect", "target",
"plan", "budget", "may", "schedule" and similar words or expressions, identify
forward-looking statements. These forward-looking statements relate to, among
other things:

    - the sufficiency of the Company's current working capital and anticipated
      operating cash flow;

    - the sufficiency of the mineral reserves and resources at Quiruvilca,
      Huaron, La Colorada, Alamo Dorado and other properties;

    - the estimated cost of and availability of funding for ongoing capital
      improvement programs;

    - the estimated cost of the proposed development of the La Colorada and
      Alamo Dorado projects;

    - estimated exploration expenditures to be incurred on the Company's various
      silver exploration properties;

    - the implementation of the Company's business strategy;

    - compliance with environmental standards;

    - forecast capital and non-operating spending; and

    - levels of silver and other metals production, production costs and metal
      prices.

    These statements reflect the Company's current views with respect to future
events and are necessarily based upon a number of assumptions and estimates that
are inherently subject to significant uncertainties and contingencies. Many
factors, both known and unknown, could cause actual results, performance or
achievements to be materially different from the results, performance or
achievements that are or may be expressed or implied by such forward-looking
statements including, without limitation, the factors identified in the
Company's Annual Information Form, dated May 20, 2003, under the caption "Trends
and Uncertainties." Investors are cautioned against attributing undue certainty
to forward-looking statements. Although the Company has attempted to identify
important factors that could cause actual results to differ materially, there
may be other factors that cause results not to be anticipated, estimated or
intended. The Company does not intend, and does not assume any obligation, to
update these forward-looking statements to reflect changes in assumptions or
changes in circumstances or any other events affecting such statements, other
than as required by applicable law.

                                  agreement; (4) indebtedness incurred specifically for the
                                  development of a particular mineral property with or without
                                  recourse to the Company; (5) all obligations to reimburse
                                  any bank or other person in respect of amounts paid under
                                  letters of credit, acceptances or other similar instruments;
                                  (6) all trade and other accounts payable for goods,
                                  materials or services purchased in the ordinary course of
                                  business; and (7) all other indebtedness of the Company
                                  unless, in the case of any particular indebtedness, the
                                  instrument creating or evidencing the same expressly
                                  provides that such indebtedness shall not be senior in right
                                  of payment to the Debentures. "Senior Indebtedness" shall
                                  not include (A) any indebtedness to the extent incurred in
                                  violation of any covenant under the Indenture; (B) any
                                  liability for foreign, federal, provincial or local taxes,
                                  subject to applicable law; (C) indebtedness that is
                                  subordinate or junior in right of payment to the Debentures;
                                  (D) any indebtedness to any employee, officer or director
                                  of the Company or any of its subsidiaries, subject to
                                  applicable law; and (E) the Debentures.

                                  The Company has agreed that, so long as any of the
                                  Debentures are issued and outstanding, neither it nor its
                                  subsidiaries will issue by public offering or private
                                  placement (whether under a prospectus or registration
                                  statement or pursuant to an exemption from the requirements
                                  therefor) any unsecured bonds, debentures, notes or other
                                  similar instruments unless all such debt is, by its terms,
                                  subordinate to the Debentures.

CONVERSION RIGHTS:                The Debentures are convertible, at the option of the holder,
                                  at any time on or prior to maturity into Common Shares at an
                                  initial conversion price of $9.57 per Common Share which is
                                  equal to a conversion rate of 104.4932 Common Shares per
                                  $1,000 principal amount of Debentures.


                                      S-7



                               
                                  Upon conversion, the receipt by a holder of Common Shares
                                  will satisfy all obligations to pay principal and accrued
                                  but unpaid interest, except if a Debenture is called for
                                  redemption upon a Change of Control or otherwise in which
                                  case a holder will receive a cash payment for accrued and
                                  unpaid interest to but excluding the date of conversion. The
                                  conversion price is subject to adjustment in certain
                                  circumstances. As a result, a holder that converts his or
                                  her Debentures prior to the record date for a periodic
                                  interest payment will not receive any interest for such
                                  period. See "Description of the
                                  Debentures -- Conversion Rights".

OPTIONAL REDEMPTION:              The Company may redeem all or any portion of the Debentures
                                  at any time on or after July 31, 2006 on at least 30 days
                                  notice but not more than 60 days notice provided that the
                                  weighted average trading price of the Common Shares on
                                  NASDAQ for the 20 consecutive trading days ending five
                                  trading days prior to the date on which notice of redemption
                                  is given, is at least 125% of the conversion price then in
                                  effect. The redemption price payable will be the principal
                                  amount of the Debentures plus all accrued but unpaid
                                  interest. See "Description of the Debentures -- Redemption".

OPTIONAL PAYMENT IN COMMON        On redemption or maturity, provided that no default or event
  SHARES ON REDEMPTION OR         of default has occurred and is continuing, the Company may
MATURITY:                         (at its option) on not less than 30 days notice and not more
                                  than 60 days notice, elect to satisfy its obligation to
                                  repay the principal amount of the Debentures by issuing and
                                  delivering that number of freely-tradable Common Shares
                                  obtained by dividing the principal amount of the outstanding
                                  Debentures to be redeemed or which have matured, by 95% of
                                  the weighted average trading price of the Common Shares on
                                  NASDAQ for the 20 consecutive trading days ending five
                                  trading days preceding the date fixed for redemption or
                                  maturity, as the case may be. All accrued but unpaid
                                  interest will be paid in cash. See "Description of the
                                  Debentures -- Share Payment Option".

CHANGE OF CONTROL:                In the event of any Change of Control of the Company, the
                                  Company will be required, within 35 days after the
                                  occurrence of a Change of Control, to make an offer to
                                  redeem all outstanding Debentures at a price equal to 101%
                                  of the principal amount of such Debentures plus accrued but
                                  unpaid interest. In addition, if the Change of Control
                                  occurs on or before July 31, 2006, the holder will also
                                  receive the present value of the amount of interest that
                                  would have been paid if the Debentures had been outstanding
                                  until July 31, 2006. If 90% or more of the aggregate
                                  principal amount of the Debentures outstanding on the date
                                  of the giving of notice of the Change of Control have been
                                  tendered to the Company for redemption, the Company will
                                  have the right and obligation to redeem all remaining
                                  Debentures on the same terms. See "Description of the
                                  Debentures -- Change of Control" for a full description of
                                  what is meant by the term "Change of Control".

SINKING FUND:                     None.

ADDITIONAL AMOUNTS AND TAX        Any payments made by the Company with respect to the
  REDEMPTION:                     Debentures will be made without withholding or deduction for
                                  Canadian taxes unless required by law. If the Company is
                                  required by law to withhold or deduct


                                      S-8



                               
                                  for Canadian taxes with respect to a payment to the holders
                                  of Debentures as a result of a change in law or policy that
                                  arises after the date of issuance of the Debenture, the
                                  Company will pay the additional amount necessary so that the
                                  net amount received by the holders of Debentures after the
                                  withholding or deduction is not less than the amount they
                                  would have received in the absence of the withholding or
                                  deduction. If the Company becomes obligated to pay such
                                  additional amounts, it shall have the right to redeem all,
                                  but not less than all, of the Debentures at an amount in
                                  cash equal to par plus accrued and unpaid interest. See
                                  "Description of the Debentures -- Additional Amounts" and
                                  "Description of the Debentures -- Redemption for Changes in
                                  Canadian Tax Law".

USE OF PROCEEDS:                  The estimated net proceeds to the Company from the sale of
                                  the Debentures offered hereby, after payment of the
                                  Underwriters' fee and the estimated expenses of this
                                  Offering, will be US$72,350,000 or, if the Over-Allotment
                                  Option is exercised in full, US$83,262,500. The net proceeds
                                  from the sale of the Debentures will be used by the Company
                                  to fund development of the Alamo Dorado project, future
                                  capital, development and exploration programs, working
                                  capital requirements and for other general corporate
                                  purposes. See "Use of Proceeds".

PRO FORMA EARNINGS COVERAGE:      On a pro forma basis after giving effect to this offering,
                                  even assuming no exercise of the Over-Allotment Option, the
                                  Company's earnings for both the fiscal year ended
                                  December 31, 2002 and the 12 month period ended March 31,
                                  2003 were insufficient to cover the interest obligations for
                                  such periods. See "Pro Forma Earnings Coverage".

DELIVERY AND FORM:                The Debentures will be issued in "book-entry only" form.
                                  This means they will be issued in the form of fully
                                  registered global debentures held by, or on behalf of, the

                                  RISK FACTORS

    PROSPECTIVE INVESTORS IN THIS OFFERING OF DEBENTURES SHOULD CONSIDER, IN
ADDITION TO THE INFORMATION CONTAINED IN THE ACCOMPANYING BASE PROSPECTUS DATED
JULY 18, 2003 AND THE RISK FACTORS NOTED BELOW, THE RISKS DESCRIBED IN THE
ANNUAL INFORMATION FORM OF THE COMPANY AND MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATION OF THE COMPANY THAT ARE
INCORPORATED BY REFERENCE INTO THIS PROSPECTUS SUPPLEMENT.

LEVEL OF INDEBTEDNESS

    After giving effect to the offering of the Debentures (assuming the
Over-Allotment Option is not exercised) and the application of the net proceeds
therefrom as described under "Use of Proceeds", as of March 31, 2003, the
Company would have had approximately $104.5 million of consolidated indebtedness
(including trade payables). In addition, the terms of the Company's bank
agreements and the Indenture governing the Debentures permit the Company and its
subsidiaries to incur additional debt.

    The Company's substantial debt may have important consequences to holders of
the Debentures. For instance, it could:

    - make it more difficult for the Company to satisfy its financial
      obligations, including those relating to the Debentures;

    - require the Company to dedicate a substantial portion of any cash flow
      from operations to the payment of interest and principal due under its
      debt, including the Debentures, which will reduce funds available for
      other business purposes;

    - increase its vulnerability to general adverse economic and industry
      conditions, including a decrease in the price of silver;

    - limit its flexibility in planning for, or reacting to, changes in its
      business;

    - place it at a competitive disadvantage compared with its competitors that
      have less debt and greater financial resources; and

    - limit its ability to obtain additional financing required to fund working
      capital and capital expenditures and for other general corporate purposes.

    The Company's ability to make payments on its indebtedness and to fund its
operations, working capital and capital expenditures, will depend on its ability
to generate cash in the future. This is subject to general economic, industry,
financial, competitive, legislative, regulatory, and other factors that are
beyond the Company's control. In particular, global or regional economic
conditions could cause the price of silver to fall and hamper the Company's
ability to repay its indebtedness, including the Debentures. The Company's
operations may not generate sufficient cash flow and borrowings may not be
available in an amount sufficient to enable the Company to pay its indebtedness,
including the Debentures, or to fund its other cash needs. The Company may need
to refinance all or a portion of its indebtedness, including the Debentures, on
or before maturity, but such refinancing may be unavailable to it on
commercially reasonable terms, or at all, to meet its obligations or to
successfully execute its business strategy.

PRIOR RANKING INDEBTEDNESS

    The Debentures will be subordinate to all present and future Senior
Indebtedness (as defined below) of the Company.

    The Indenture will not limit the ability of the Company to incur additional
Senior Indebtedness (defined as secured debt and bank/institutional debt,
project debt and trade debt, whether secured or

                                      S-10

unsecured) or indebtedness that is by its terms subordinate to the Debentures.
The Indenture does not contain any provisions specifically intended to protect
the holders of the Debentures in the event of a future leveraged transaction
involving the Company. In the event of any distribution or payment of the
Company's assets in any foreclosure, dissolution, winding-up, liquidation,
reorganization, or other bankruptcy proceeding, holders of secured indebtedness
will have prior claim to those of the Company's assets that constitute their
collateral. Holders of the Debentures will participate ratably with all holders
of the Company's unsecured indebtedness that is deemed to be of the same class
as the Debentures, and potentially with all of the Company's other general
creditors, based upon the respective amounts owed to each holder or creditor, in
the Company's remaining assets. In any of the foregoing events, there can be no
assurance that there will be sufficient assets to pay amounts due on the
Debentures.

SUBORDINATION IN RIGHT OF PAYMENT TO THE OBLIGATIONS OF SUBSIDIARIES

    A significant portion of the Company's operations is conducted by its
subsidiaries, which own most of the Company's consolidated assets. The operating
cash flow of the Company's subsidiaries and the payment of funds by them to the
Company in the form of loans, dividends or otherwise could, in certain
circumstances, affect the Company's operating cash flow and its ability to
service its indebtedness, including the Debentures. The Company's subsidiaries
are separate legal entities that have no obligation to pay any amounts due
pursuant to the Debentures or to make any funds available for that purpose,
whether by dividend, interest, loans, advances or other payments. In addition,
their ability to pay dividends and make loans, advances and other payments to
the Company may be restricted by contractual restrictions, which may include
requirements to maintain minimum levels of working capital and other assets.

    A holder's right to receive payments under the Debentures will be
effectively subordinate to all current and future debts and liabilities of the
Company's subsidiaries. In the event of a bankruptcy, liquidation, winding up,
reorganization or similar proceeding relating to a subsidiary, the Company's
right to receive assets of that subsidiary and a holder's consequent right to
participate in a distribution of those assets will rank behind that subsidiary's
creditors, including trade creditors. As of March 31, 2003, the indebtedness
(including trade payables), excluding intercompany indebtedness, of the
Company's subsidiaries was $29.5 million. The Company's subsidiaries may also
incur additional debt and liabilities in the future.

RIGHT OF EARLY REDEMPTION

    Purchasers of the Debentures should be aware that the Company may redeem all
or part of the Debentures at any time on and after July 31, 2006 subject to
certain conditions and at any time in the event of certain changes in Canadian
tax laws at a price equal to the principal amount of the Debentures redeemed
plus accrued and unpaid interest. The Company may, in some circumstances, also
elect to satisfy the redemption price in cash or by delivering Common Shares in
lieu of cash. See "Description of The Debentures -- Redemption".

BANKRUPTCY AND RELATED LAWS

    The Company is incorporated under the laws of British Columbia and its
principal operating assets are located outside of Canada and the United States.
Under bankruptcy laws in the United States, courts typically have jurisdiction
over a debtor's property, wherever located, including property situated in other
countries.

    The rights of the Trustee to enforce remedies are likely to be significantly
impaired by the restructuring provisions of applicable Canadian federal
bankruptcy, insolvency and other restructuring legislation if the benefit of
such legislation is sought with respect to the Company. For example, both

                                      S-11

the BANKRUPTCY AND INSOLVENCY ACT (Canada) and the COMPANIES' CREDITORS
ARRANGEMENT ACT (Canada) contain provisions enabling "an insolvent person" to
obtain a stay of proceedings as against its creditors and others and to prepare
and file a proposal for consideration by all or some of its creditors to be
voted on by the various classes of its creditors. Such a restructuring proposal,
if accepted by the requisite majorities of creditors and if approved by the
court, would be binding on persons who might not otherwise be willing to accept
it. Moreover, this "proposal" legislation permits, in certain circumstances, the
insolvent debtor to retain possession and administration of its property, even
though it may be in default under the applicable debt instrument.

    The powers of the court under the BANKRUPTCY AND INSOLVENCY ACT (Canada) and
particularly under the COMPANIES' CREDITORS ARRANGEMENT ACT (Canada) have been
exercised broadly to protect a restructuring entity from actions taken by
creditors and other parties. Accordingly, it is impossible to predict if
payments under the Debentures would be made following commencement of or during
such a proceeding, whether or when the Trustee could exercise its rights under
the Indenture or whether and to what extent holders of the Debentures would be
compensated for any delay, if any, in payments of principal and interest.

COMMON SHARE PRICE VOLATILITY

    The Company expects the market price of the Debentures to be significantly
affected by the market price of its Common Shares. This may result in greater
volatility in the trading value of the Debentures than would be expected for
nonconvertible securities issued by the Company. In addition, the Debentures
have a number of features, which, if not met, could result in a holder receiving
less than the value of the Common Shares into which a Debenture is otherwise
convertible. These features could adversely affect the value and trading prices
of the Debentures.

    The trading price of the Common Shares has been and may continue to be
subject to large fluctuations and, therefore, the trading price of the
Debentures may fluctuate significantly, which may result in losses to investors.
The price of the Common Shares may increase or decrease in response to a number
of events and factors, including:

    - trends in the silver mining industry and the markets in which the Company
      operates;

    - changes in the market price of the commodities the Company sells;

    - current events affecting the economic situation in Canada and the
      United States;

    - changes in financial estimates and recommendations by securities analysts;

    - acquisitions and financings;

    - quarterly variations in operating results;

    - the operating and share price performance of other companies that
      investors may deem comparable; and

    - purchase or sales of blocks of the Common Shares.

    This volatility may adversely affect the prices of the Common Shares and the
Debentures regardless of the Company's operating performance.

FAILURE OF AN ACTIVE TRADING MARKET FOR THE DEBENTURES TO DEVELOP

    The Debentures are a new issue of securities for which there is currently no
trading market. Although the TSX has conditionally approved the listing of the
Debentures, no assurance can be given that an active trading market for the
Debentures will develop or be sustained. If an active market for the Debentures
fails to develop or be sustained, the Debentures could trade at prices that may
be

                                      S-12

lower than the initial offering price of the Debentures. Whether or not the
Debentures will trade at lower prices depends on many factors, including:

    - prevailing interest rates and the markets for similar securities;

    - the market price of the Common Shares;

    - general economic conditions; and

    - the Company's financial condition, historic financial performance and
      future prospects.

INABILITY TO FUND PURCHASE OF DEBENTURES

    Upon the occurrence of certain specific kinds of change of control events
occurring before maturity of the Debentures, the Company will be required to
make an offer to redeem all outstanding Debentures. However, it is possible that
following a change of control the Company will not have sufficient funds at that
time to make the required redemption of outstanding Debentures. See "Description
of the Debentures -- Change of Control".

CONVERSION FOLLOWING CERTAIN TRANSACTIONS

    In the case of certain transactions, each Debenture will become convertible
into the securities, cash or property receivable by a holder of Common Shares in
the kind and amount of securities, cash or property into which the Debenture was
convertible immediately prior to the transaction. This change could
substantially lessen or eliminate the value of the conversion privilege
associated with the Debentures in the future. For example, if the Company were
acquired in a cash merger, each Debenture would become convertible solely into
cash and a holder may not be able to reinvest the cash to receive an equivalent
rate of return and will lose the opportunity to participate in any increase in
the value of the Common Shares, if any. See "Description of the
Debentures -- Conversion Rights".

EARNINGS COVERAGE DEFICIENCY

    On a pro forma basis after giving effect to this Offering, even assuming no
exercise of the Over-Allotment Option, the Company's earnings for both the
fiscal year ended December 31, 2002 and the 12 month period ended March 31, 2003
were insufficient to cover the interest obligations for such periods. See
"Pro Forma Earnings Coverage". There can be no assurance that the Company will,
in the future, have sufficient funds to make such payments.

EMPLOYEE RELATIONS

    Certain of the Company's employees and the employees of Peruvian mining
contractors indirectly employed by the Company are represented by unions. At
July 23, 2003, there were 71 employees represented by the Sindicato de
Trebajadores de Pan American Silver S.A.C. -- Mina Quiruvilca (the "Quiruvilca
Union") and 266 employees represented by the Sindicato de Trebajadores de Shorey
y Anexos (the "Shorey Union"). There are also 17 employees at the Huaron mine
who are members of a "union committee" who have rights pursuant to an agreement
dated January 1, 2003. The Company has experienced labour strikes and work
stoppages in the past. The labour agreements with the Quiruvilca Union and the
Shorey Union expired on January 1, 2003, and ordinary course negotiations to
renew the contracts are ongoing. There can be no assurance that these contracts
will be renewed on terms favourable to the Company, if at all and the Company
may experience future work stoppages.

ACQUISITIONS

    An element of the Company's business strategy is to make selected
acquisitions. For example, the Company recently completed the acquisition of
Corner Bay Silver Inc. in February 2003. The Company

                                      S-13

expects to continue to evaluate acquisition opportunities on a regular basis and
intends to pursue those opportunities that it believes are in its long-term best
interests. The success of the Company's acquisitions will depend upon its
ability to effectively manage the operations of entities it acquires and to
realize other anticipated benefits. The process of managing acquired businesses
may involve unforeseen difficulties and may require a disproportionate amount of
management resources. There can be no assurance that the Company will be able to
successfully manage the operations of businesses it acquires or that the
anticipated benefits of its acquisitions will be realized. In addition, the
Company may issue additional Common Shares in connection with aquisitions. These
share issuances may cause dilution to holders of Debentures to the extent they
wish to or are required to, acquire Common Shares in replacement of the
principal amount of the Debentures.

HEDGING ACTIVITIES

    From time to time, the Company engages in hedging activities in connection
with base metals, such as forward sales contracts and commodity put and call
option contracts, to minimize the effect of declines in metal prices on our
operating results. While these hedging activities may protect the Company
against low metal prices, they may also limit the price the Company can receive
on hedged products. As a result, the Company may be prevented from realizing
possible revenues in the event that the market price of a metal exceeds the
price stated in a forward sale or call option contract. As of March 31, 2003,
the Company's forward contract position had a value of $264,000. In addition,
the Company may experience losses if a counterparty fails to purchase under a
contract when the contract price exceeds the spot price of a commodity. The
Company's current policy is to not hedge the price of silver and therefore it is
fully exposed to declines in silver prices.

ENFORCING CIVIL LIABILITIES IN THE UNITED STATES

    The Company is organized under the laws of the Province of British Columbia,
and its principal executive office is located in British Columbia. Many of the
Company's directors, controlling persons, officers and the experts named in this
prospectus are residents of Canada, and a substantial portion of the their
assets and a majority of the Company's assets are located outside the
United States. As a result, it may be difficult for U.S. investors to effect
service of process within the United States upon the directors, controlling
persons, officers and the experts who are not residents of the United States or
to enforce against them judgments of United States courts based upon civil
liability under the federal securities laws of the United States. There is doubt
as to the enforceability in Canada against the Company or against any of its
directors, controlling persons, officers or experts who are not residents of the
United States, of original actions or actions for enforcement of judgments of
United States courts of liabilities based solely upon the federal securities
laws of the United States.

                          PRO FORMA EARNINGS COVERAGE

    The following consolidated financial earnings deficiency figures and cash
flow coverage ratios are calculated, on a pro forma basis, for the fiscal year
ended December 31, 2002 and the 12 month period ended March 31, 2003. In
addition, all figures and ratios give effect to all long-term financial
liabilities of the Company and the repayment, redemption or retirement thereof
since those dates, respectively as well as the issuance of US$75,000,000
principal amount of Debentures hereunder. All amounts are

                                      S-14

calculated assuming there is no exercise of the Over-Allotment Option. All
deficiency figures and coverage ratios have been calculated based on
Canadian GAAP.

(2) Pro forma earnings coverage deficiency is the dollar amount of earnings
    required to attain an earnings coverage ratio of one-to-one. Earnings
    coverage ratio is equal to net income before pro forma interest expense and
    income taxes divided by pro forma interest expense on all debt.

(3) Pro forma earnings coverage deficiency before interest, taxes and unusual
    items is the dollar amount of earnings required to attain an earnings
    coverage ratio before interest, taxes and unusual items of one-to-one.
    Pro forma earnings coverage ratio before interest, taxes and unusual items
    is equal to net income before pro forma interest expense, income taxes and
    write-down of the Company's investment in the Quiruvilca mine and accrual
    for future reclamation costs for the Quiruvilca Mine divided by pro forma
    interest expense on all debt.

(4) Cash flow coverage ratio is equal to cash flow from operating, financing and
    investment activities before interest paid and income taxes divided by pro
    forma interest expense on all debt.

    The foregoing table illustrates that the Company's earning coverage ratio
for the indicated periods, on a pro forma basis, would have been insufficient to
meet its interest obligations if the Debentures had been outstanding during such
periods.

                                      S-15

                         DESCRIPTION OF THE DEBENTURES

    The Debentures will be issued under a trust indenture to be dated as of the
closing date (the "Indenture") between the Company and Computershare Trust
Company of Canada, as trustee (the "Trustee"). The Indenture will be subject to
the provisions of the COMPANY ACT (British Columbia) and the United States Trust
Indenture Act of 1939, as amended (the "TIA"), to the extent set forth in
Rule 4d-9 thereunder.

    The following summary of certain provisions of the Debentures and the
Indenture does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, all of the provisions of the Debentures and the
Indenture, including the definitions therein of certain terms that are not
otherwise defined in this prospectus supplement. Wherever particular provisions
or defined terms of the Indenture (or of the Form of Debentures, which is a part
thereof) are referred to, such provisions or defined terms are incorporated
herein by reference.

GENERAL

    The Debentures will be subordinated unsecured general obligations of the
Company and are convertible into Common Shares, at the option of the holders, as
described under "Description of the Debentures -- Conversion Rights". The
Debentures will be limited in aggregate principal amount to $75,000,000
($86,250,000 if the Over-Allotment Option is exercised in full) and will mature
on July 31, 2009, unless earlier, converted or redeemed by the Company as
described herein. The principal amount of each Debenture will be $1,000 and will
be payable at the office of the Trustee.

    The Debentures will bear interest at the rate of 5.25% per annum on the
principal amount from July 30, 2003, or from the most recent date to which
interest has been paid or provided for until the Debentures are paid in full,
converted or funds are made available for payment in full of the Debentures in
accordance with the Indenture. Interest will be payable at the date of maturity
(or earlier redemption or, in some circumstances, conversion) and semi-annually
on January 31 and July 31 of each year (each an "Interest Payment Date"),
commencing on January 31, 2004. In all cases, interest payments will be made to
holders of record at the close of business on January 15 and July 15 preceding
each Interest Payment Date (each, a "Regular Record Date"). Any interest
payments will be payable in cash or, at the option of the Company, by delivery
of Common Shares to the Trustee for sale on the open market to fund the
Company's cash obligation with respect to the payment of interest on the
Interest Payment Date (See "Description of the Debentures -- Share Payment
Option -- Payment of Interest"). Each payment of interest on the Debentures will
include interest accrued to, but excluding, the applicable Interest Payment Date
or the date of maturity (or earlier redemption or, in some circumstances,
conversion), as the case may be. Any payment of principal and cash interest
required to be made on any day that is not a business day will be made on the
next succeeding business day (and without any interest or other payment in
respect of any such delay). Interest will be computed on the basis of a
365-day year.

    In the event of conversion, redemption, or maturity, interest will cease to
accrue on that Debenture, except as provided in the Indenture; provided,
however, if the Company defaults on its obligation to deliver Common Shares and
cash in lieu of fractional shares upon conversion, redemption or maturity, as
applicable, or defaults on its obligation to deliver cash upon redemption or
maturity, as applicable, interest will continue to accrue on that Debenture
until such default has been cured, in all cases, subject to the terms and
conditions of the Indenture. The Company may not re-issue a Debenture that has
matured or has been converted, redeemed or otherwise cancelled.

    The Indenture also does not contain any covenants or other provisions to
protect holders of the Debentures in the event of a highly leveraged transaction
or a Change of Control, except to the extent described under "Description of the
Debentures -- Change of Control".

                                      S-16

SUBORDINATION

    The Indenture will provide that the Debentures will be subordinated and
junior in right of payment to all present and future Senior Indebtedness of the
Company. "Senior Indebtedness" is defined as (1) all indebtedness secured by a
lien or other encumbrance; (2) all other indebtedness including monetary
obligations under credit facilities, with any bank, insurance company,
investment fund, credit union or other financial institution; (3) any interest
rate agreement or currency agreement; (4) indebtedness incurred specifically for
the development of a particular mineral property with or without recourse to the
Company; (5) all obligations to reimburse any bank or other person in respect of
amounts paid under letters of credit, acceptances or other similar instruments;
(6) all trade and other accounts payable for goods, materials or services
purchased in the ordinary course of business; and (7) all other indebtedness of
the Company unless, in the case of any particular indebtedness, the instrument
creating or evidencing the same expressly provides that such indebtedness shall
not be senior in right of payment to the Debentures. "Senior Indebtedness" shall
not include (A) any indebtedness to the extent incurred in violation of any
covenant under the Indenture; (B) any liability for foreign, federal, provincial
or local taxes, subject to applicable law; (C) indebtedness that is subordinate
or junior in right of payment to the Debentures; (D) any indebtedness to any
employee, officer or director of the Company or any of its subsidiaries, subject
to applicable law; and (E) the Debentures.

    The Debentures will rank PARI PASSU with all other present or future
unsecured indebtedness that is not Senior Indebtedness and that is not expressly
subordinate to the Debentures.

    The Company has agreed that, so long as Debentures are issued and
outstanding, neither it nor its subsidiaries will issue by public offering or
private placement (whether under a prospectus or registration statement or
pursuant to an exemption from the requirements therefor) any unsecured bonds,
debentures, notes or other capital markets debt securities unless all such
indebtedness is by its terms expressly subordinate to the Debentures.

    After giving effect to the offering of the Debentures (assuming the
Over-Allotment Option is not exercised) and the application of the net proceeds
as described under "Use of Proceeds", as of March 31, 2003, the Company would
have had approximately $104.5 million of consolidated indebtedness (including
trade payables), of this $8.7 million would have been secured indebtedness of
the Company and $20.8 million would have been unsecured indebtedness of the
Company's subsidiaries.

    In addition, the Debentures will effectively be subordinated to all existing
and future liabilities of the Company's subsidiaries. Any rights of the Company
to receive assets of any subsidiary upon its liquidation or reorganization and
the consequent right of holders of the Debentures to participate in those assets
will be subject to the claims of that subsidiary's creditors, including trade
creditors, except to the extent that the Company is recognized as a creditor of
that subsidiary, in which case the Company's claim would still be subordinate to
any security interests in the assets of that subsidiary.

CONVERSION RIGHTS

    A holder of a Debenture is entitled to convert the Debenture into Common
Shares at any time on or prior to the close of business on the last business day
prior to the date of maturity, provided that if a Debenture is called for
redemption, the holder is entitled to convert it at any time before the close of
business on the last business day prior to the redemption date. In the case of a
Change of Control (as defined below), a Debenture in respect of which a holder
has delivered a notice accepting a Debenture Offer (as defined below) may be
converted only if such notice is withdrawn by a written notice of withdrawal
delivered by the holder to the Trustee prior to the close of business on the
Change of Control redemption date, in accordance with the terms of
the Indenture.

                                      S-17

    The receipt by a holder of Common Shares upon a conversion will satisfy all
obligations to pay principal and accrued but unpaid interest, except if a
Debenture is called for redemption upon a Change of Control or otherwise, in
which case a holder will receive a cash payment for accrued but unpaid interest
to but excluding the date of conversion.

    The initial conversion price for the Debentures is $9.57 per Common Share
(the "Conversion Price"), which is equal to a conversion rate of 104.4932 shares
per $1,000 principal amount of Debentures. The Conversion Price is subject to
adjustment upon the occurrence of certain events as described below. A holder
otherwise entitled to a fractional Common Share will receive cash in
United States dollars in an amount equal to the Conversion Price on the trading
day immediately preceding the conversion date. A holder may convert a portion of
that holder's Debentures so long as that portion is $1,000 principal amount or
an integral multiple of $1,000. A holder who converts his or her Debentures
prior to the record date for a periodic interest payment will not receive any
interest for such period.

    A certificate for the number of Common Shares into which any Debenture is
converted and any cash payment to be made instead of any fractional shares will
be delivered as soon as practicable, but in any event no later than the fifth
business day following the conversion date. For a summary of the Canadian and
United States federal income tax treatment of a holder receiving Common Shares
upon conversion, see "Income Tax Considerations -- Certain Canadian Federal
Income Tax Considerations -- Exercise of Conversion Right" and "Income Tax
Considerations -- Certain United States Federal Income Tax
Considerations -- Conversion of the Debentures," respectively.

    The Conversion Price is subject to adjustment in some events, including:

    - the issuance of Common Shares as a dividend or a distribution with respect
      to the Common Shares;

    - subdivisions and combinations of the Common Shares;

    - the issuance to all holders of Common Shares of certain rights to
      purchase, for a period not exceeding 45 days, Common Shares at less than
      95% of the Current Market Price of a Common Share (as defined under
      "Description of the Debentures -- Share Payment Option" below);

    - the distribution to holders of Common Shares of evidences of the Company's
      indebtedness, capital stock, cash or assets (including securities, but
      excluding Common Share distributions covered above, those rights,
      dividends and distributions referred to above, and dividends and
      distributions paid exclusively in cash, excepts as set out below);

    - the payment of dividends or other distributions in cash to holders of
      Common Shares to the extent that the aggregate amount of such cash
      dividends or other distributions in any 12 month period exceeds 1% of the
      Current Market Price; and

    - an issuer bid, tender offer or exchange offer is made for all or any
      portion of the Common Shares by the Company or any of its subsidiaries to
      the extent the consideration paid to such holders exceeds 5% of the
      Company's aggregate market capitalization.

    However, adjustment of the Conversion Price is not necessary if holders may
participate in the transactions otherwise giving rise to an adjustment on a
basis as though and to the same effect as if such holders had converted their
Debentures into Common Shares prior to the record date for such transaction.

    No adjustment to the Conversion Price will be required unless such
adjustment would require a change of at least 1% in the Conversion Price then in
effect at such time. Any adjustment that would otherwise be required to be made
shall be carried forward and taken into account in any subsequent adjustment.
Except as stated above, the Conversion Price will not be adjusted for the
issuance of the Common Shares or any securities convertible into or exchangeable
for the Common Shares or carrying the right to purchase any of the foregoing.

                                      S-18

    A U.S. person may, in certain circumstances, be deemed to have received a
distribution subject to United States federal income tax as a dividend, upon a
taxable distribution to holders of Common Shares that results in an adjustment
to the Conversion Price. See "Income Tax Considerations -- Certain Material
United States Federal Income Tax Considerations".

    The Company may, from time to time, to the extent permitted by law and
subject to receipt of all necessary regulatory approvals, decrease the
Conversion Price by any amount for a period of at least 20 business days if the
Company's Board of Directors has determined in good faith (to be evidenced by a
resolution of the Board of Directors) that such decrease would be in the best
interests of the Company. The Company will give notice of such a decrease to the
Trustee at least 15 days before such decrease becomes effective.

    In the event that the Company becomes a party to any transaction, including,
and with some exceptions:

    - any recapitalization or reclassification of the Common Shares;

    - any consolidation, amalgamation or combination of the Company with, or
      merger of the Company into, any other Person, or any merger of another
      Person into the Company; or

    - any sale, transfer or lease of all or substantially all of the
      Company's assets;

pursuant to which the Common Shares are converted into the right to receive
other securities, cash or other property (each of the above being referred to as
a "Transaction"), then the holders of Debentures then outstanding will have the
right to convert the Debentures only into the kind and amount of securities,
cash or other property receivable upon the consummation of that Transaction by a
holder of the number of Common Shares issuable upon conversion of those
Debentures immediately prior to that Transaction. The holders of Debentures will
have no voting rights with respect to any Transaction.

    However, if a Transaction occurs on or before the date which is five years
after the issuance of the Debentures, the consideration into which the
Debentures will be convertible will be limited to the Common Shares or other
prescribed securities (within the meaning of the INCOME TAX ACT (Canada)) of the
Company as specified by the Board of Directors, which includes shares not
redeemable by the holder within five years after the issuance of the Debentures.
As a result, in these circumstances, the consideration issuable on the exercise
of the conversion right could differ from the consideration received by the
holders of Common Shares pursuant to the Transaction, and the conversion rate
could be adjusted so that the consideration into which the Debentures are
convertible after the Transaction is, immediately following the date of the
Transaction, equivalent in value to the value, immediately following the date of
the Transaction, of the consideration a holder would have been entitled to
receive had the holder converted the Debentures into Common Shares immediately
prior to the Transaction. In addition, if the Transaction entails the exchange
of substantially all of the Common Shares for cash (or securities that are
redeemable for cash within 60 days of issue), the Debentures may cease to be
convertible, potentially making it desirable for the holder to exercise its
conversion right prior to the applicable date for such Transaction.

    Where, as a result of a Transaction, the Debentures become convertible into
the kind and amount of securities, cash or property receivable by a holder of
the number of Common Shares issuable upon conversion of those Debentures
immediately prior to that Transaction, the value of the conversion privilege
associated with the Debentures in the future could be substantially lessened or
eliminated. For example, if all of the Common Shares were to be acquired for
cash consideration, each Debenture would become convertible solely into cash and
would no longer be convertible into securities whose value would vary depending
on the Company's future prospects and other factors.

    In the event of a taxable distribution to holders of the Common Shares that
results in an adjustment of the Conversion Price, or in which holders otherwise
participate, or in the event the Conversion Price is decreased at the Company's
discretion, the holders of the Debentures may, in some

                                      S-19

circumstances, be deemed to have received a distribution subject to
United States federal income tax as a dividend. Moreover, in some other
circumstances, the absence of an adjustment to the Conversion Price may result
in a dividend to holders of Common Shares taxable under United States federal
income tax law. See "Income Tax Considerations -- Certain United States Federal
Income Tax Considerations -- Adjustments in the Conversion Price of
the Debentures".

REDEMPTION

    OPTIONAL REDEMPTION

    Except to the extent described under "Redemption for Changes in Canadian Tax
Laws" and "Change of Control", the Debentures will not be redeemable prior to
July 31, 2006. On or after July 31, 2006, the Debentures will be redeemable in
whole at any time or in part from time to time, on at least 30 days' but not
more than 60 days' prior notice of redemption given to holders of Debentures, at
a redemption price equal to par plus accrued and unpaid interest thereon to but
excluding the redemption date, provided that the Current Market Price (as
defined below) is at least 125% of the Conversion Price. Any redemption of
Debentures must be in integral multiples of $1,000 principal amount. The
redemption price will be payable in cash or, at the option of the Company, the
redemption price may be paid by delivery of freely tradeable Common Shares,
except as to any fractional amount which shall be paid in cash in lieu thereof.
Any accrued but unpaid interest will be payable in cash. See "Description of the
Debentures -- Share Payment Option".

    If fewer than all of the Debentures are to be redeemed, the Trustee will
select the Debentures to be redeemed in principal amounts of $1,000 or integral
multiples of $1,000, PRO RATA or by another method that complies with the
requirements of the TSX, or any stock exchange on which the Debentures are
listed or quoted and that the Trustee shall deem equitable. If a portion of a
holder's Debentures is selected for partial redemption and that holder converts
all or a portion of such Debentures prior to the redemption, the converted
portion will be deemed, solely for purposes of determining the aggregate
principal amount of the Debentures to be redeemed by the Company, to form a
portion of those Debentures selected for redemption.

    There is no sinking fund for the Debentures.

    REDEMPTION FOR CHANGES IN CANADIAN TAX LAW

    In addition, the Debentures are redeemable, in whole but not in part, at the
option of the Company for cash in United States dollars at any time upon not
less than 30 days' nor more than 60 days' notice at a redemption price equal to
par plus accrued and unpaid interest thereon to but excluding the redemption
date, in the event that the Company has become or would become obligated to pay,
on the next date on which any amount would be payable under or with respect to
the Debentures, any Additional Amounts (as defined below) as a result of any
change in, or amendment to, the laws (or any regulations promulgated thereunder)
of Canada (or any political subdivision or taxing authority thereof or therein),
or any change in, or amendment to, any official position regarding the
application or interpretation of such laws or regulations, which change or
amendment is announced or becomes effective on or after the date of this
prospectus supplement; provided that the Company determines that the obligation
to pay such Additional Amounts cannot be avoided by the use of reasonable
measures available to the Company (not including substitution of the obligor
under the Debentures).

    No Debentures may be redeemed by the Company pursuant to the provisions
described above if there has occurred and is continuing an Event of Default
described under "Description of Debentures -- Events of Default".

                                      S-20

SHARE PAYMENT OPTION

    PAYMENT OF PRINCIPAL ON REDEMPTION OR AT MATURITY

    For so long as the Common Shares are listed on NASDAQ or a stock exchange in
the United States or Canada, the Company may at its option and subject to
receiving all applicable regulatory approvals, unless an Event of Default has
occurred and is continuing, elect to satisfy all or a portion of its obligations
to pay the outstanding principal amount of Debentures upon redemption or
maturity for any reason (other than redemption for changes in Canadian tax
laws), by issuing and delivering to the registered holder, for each
$1,000 principal amount of Debentures, that number of fully paid and
non-assessable and freely tradeable (in the United States and Canada) Common
Shares equal to the principal amount divided by 95% of the Current Market Price
(as defined below) of the Common Shares on the date of redemption or maturity,
as applicable (the "Share Payment Option"), together with a cash amount equal to
the amount of all accrued and unpaid interest. No fractional Common Shares will
be issued to the holders of Debentures, but, in lieu thereof, the Company will
make a cash payment.

    To exercise the Share Payment Option, the Company must give not less than
30 days' and not more than 60 days' prior notice of such election to the Trustee
and the affected registered holders.

    "Current Market Price" of the Common Shares means an amount equal to the
weighted average trading price of the Common Shares on NASDAQ (or, if the Common
Shares are not listed on the NASDAQ, then the TSX or such other stock exchange
in Canada or in the United States on which the Common Shares are then listed)
for 20 consecutive trading days ending five trading days prior to the date
of determination.

    PAYMENT OF INTEREST

    Subject to receiving applicable regulatory approvals, the Company shall have
the right to elect, from time to time, to issue and deliver Common Shares to the
Trustee (the "Share Interest Payment Election") for sale in the open market to
raise funds in order to satisfy its obligation to pay interest on the Debentures
(the "Interest Obligation").

    Neither the Company's making of the Share Interest Payment Election nor the
consummation of sales of the Common Shares will (i) result in the holders of the
Debentures not being entitled to receive, in accordance with the foregoing
procedures, on the applicable Interest Payment Date cash in an aggregate amount
equal to the interest payable on such Interest Payment Date or (ii) entitle such
holders to receive any Common Shares in satisfaction of the Company's obligation
to pay such interest.

CHANGE OF CONTROL

    Within 35 days following the occurrence of a change of control of the
Company involving the acquisition of beneficial voting control or direction over
66 2/3% or more of the issued and outstanding Common Shares (a "Change of
Control"), the Company will be required to make an offer in writing to redeem
all of the Debentures then outstanding (the "Debenture Offer"), at a cash price
equal to the sum of: (i) 101% of the principal amount thereof (ii) accrued and
unpaid interest; and (iii) in the event that the Change of Control occurs on or
before July 31, 2006, the present value of the amount of interest which would
have accrued and been paid on the Debentures if the Debentures were outstanding
until July 31, 2006 (the "Debenture Offer Price"). The present value of the
amount of interest that would have accrued and been paid on the Debentures will
be computed using a discount rate equal to the US Treasury Yield. The
"US Treasury Yield" means the yield to maturity (as published by the Federal
Reserve, or any other publicly available source for such market data, at the
time of computation) of US Treasury securities with a constant maturity equal to
the then remaining term to July 31, 2006, provided, however, that if the then
remaining term to July 31, 2006 is not equal to the constant maturity of a
US Treasury security for which a yield to maturity is available, the
US Treasury Yield shall be obtained by linear interpolation (calculated to the
nearest one-twelfth of a

                                      S-21

year) from the weekly average yields of US Treasury securities for which such
yields are given, except that if the then remaining term of July 31, 2006 is
less than one year, the weekly average yield on US Treasury securities adjusted
to a constant maturity of one year shall be used.

    The Indenture contains notification and redemption provisions requiring the
Company to give written notice to the Trustee of the occurrence of a Change of
Control within 35 days of such event together with the Debenture Offer. The
Trustee will thereafter promptly mail to each holder of Debentures a notice of
the Change of Control together with a copy of the Debenture Offer to redeem all
the outstanding Debentures.

    The Company will comply with the provisions of Rule 13e-4 and any other
tender offer rules under the Exchange Act or other relevant Canadian and
United States federal, provincial and state securities legislation that may then
be applicable in connection with any Debenture Offer.

    If 90% or more of the aggregate principal amount of the Debentures
outstanding on the date of the giving of notice of the Change of Control have
been tendered to the Company for redemption pursuant to the Debenture Offer, the
Company will have the right and obligation to redeem all the remaining
Debentures at the Debenture Offer Price. Notice of such redemption must be given
by the Company to the Trustee within 10 days following the expiry of the
Debenture Offer, and as soon as possible thereafter, by the Trustee to the
holders of the Debentures not tendered pursuant to the Debenture Offer.

    If a Change of Control was to occur, there can be no assurance that the
Company would have funds sufficient to pay the Debenture Offer Price for all of
the Debentures that might be delivered by holders seeking to accept a Debenture
Offer. Further, payment of the Debenture Offer Price for the Debentures may be
subordinated to the prior payment of Senior Indebtedness as described under
"Description of the Debentures -- Subordination". In addition, the Company's
ability to purchase Debentures with cash may be limited by the terms of its
current and future debt agreements.

    The obligations of the Company arising upon a Change of Control will also be
satisfied if a third party makes the Debenture Offer in the manner and at the
times and otherwise in compliance with the requirements applicable to a
Debenture Offer made by the Company. The failure of the Company (or a third
party, in the case of a Debenture Offer made by a third party) to make or
consummate the Debenture Offer or pay the Debenture Offer Price when due will
give the Trustee and the holders the rights described under "Description of the
Debentures -- Events of Default".

CONSOLIDATION, MERGER AND SALE OF ASSETS

    The Company, without the consent of any holders of outstanding Debentures,
is entitled to amalgamate with, consolidate with or merge into, or sell,
transfer, assign or lease all or substantially all the Company's assets to any
individual, corporation, partnership, limited liability company, joint venture,
association, trust, unincorporated organization or government or any agency or
political subdivision thereof (each a "Person") provided that:

    - the Person, if other than the Company, formed by a consolidation or into
      which the Company is merged, or the Person, if other than one of the
      Company's subsidiaries, which receives the transfer of all or
      substantially all the Company's assets, expressly assumes the Company's
      obligations on the Debentures and under the Indenture;

    - the Trustee is satisfied that the transaction will not result in the
      successor Person being required to make any deduction or withholding on
      account of certain Canadian taxes from any payments in respect of
      the Debentures;

    - immediately before or after giving effect to the consolidation, merger,
      transfer, assignment or lease, no Event of Default (as defined below), and
      no event which, after notice or lapse of time or both, would become an
      Event of Default, has happened and is continuing; and

                                      S-22

    - an officer's certificate and an opinion of counsel, each stating that the
      amalgamation, consolidation, merger, transfer, assignment or lease
      complies with the provisions of the Indenture, have been delivered by the
      Company to the Trustee.

    Upon the assumption of the Company's obligations by another Person in these
circumstances, the Company will be discharged from its obligations with respect
to the Debentures in accordance with the terms and conditions of the Indenture.
In addition, certain of these transactions could constitute a Change of Control,
requiring the Company to make a Debenture Offer.

EVENTS OF DEFAULT

    The Indenture provides that if an Event of Default specified in the
Indenture occurs and is continuing, either the Trustee or the holders of not
less than 25% in aggregate principal amount of the Debentures then outstanding
may declare the principal amount of and accrued interest to the date of that
declaration on all the Debentures to be immediately due and payable. In the case
of some events of bankruptcy or insolvency, the principal amount of, and accrued
interest on, all the Debentures to the date of the occurrence of that event
automatically will become and immediately will be due and payable.

    Under some circumstances, the holders of a majority in aggregate principal
amount of the Debentures may rescind any acceleration with respect to the
Debentures and its consequences. Interest will continue to accrue and be payable
on demand upon a default in:

    - the payment of:

       - principal or interest when due,

       - redemption amounts, or

       - the Debenture Offer Price;

    - the delivery of Common Shares to be delivered on conversion of the
      Debentures; or

    - the payment of cash in lieu of fractional shares to be paid on conversion
      of the Debentures.

    Under the Indenture, Events of Default include:

    - failure by the Company to pay principal on the Debentures in cash or
      pursuant to the Share Payment Option when due, whether at maturity, upon
      redemption, or otherwise and such default continues for five business
      days;

    - failure by the Company to pay interest on the Debentures in cash when due
      and such default continues for a period of 15 business days;

    - failure by the Company to pay the Debenture Offer Price when due;

    - failure by the Company to deliver Common Shares together with cash in
      United States dollars in lieu of fractional shares, when those Common
      Shares or cash in United States dollars in lieu of fractional shares, are
      required to be delivered following conversion of a Debenture and that
      default continues for 10 days;

    - failure by the Company to make a Debenture Offer within 35 days of the
      occurrence of the Change of Control;

    - failure by the Company to comply with any material term, covenant or other
      agreements in the Debentures or the Indenture for a period of 30 days
      after the receipt by the Company of written notice to remedy that default
      from the Trustee or from holders of not less than 25% in aggregate
      principal amount of the Debentures then outstanding;

    - a failure by the Company to pay when due at maturity or upon a default,
      event of default or similar condition under any bond, note, debenture or
      other evidence of indebtedness for money borrowed by the Company or any of
      its subsidiaries having an aggregate outstanding principal

                                      S-23

      amount in excess of $10 million, not including any amounts the Company may
      owe under reimbursement or similar obligations to banks, sureties or other
      entities that have issued letters of credit, surety bonds, performance
      bonds or other guarantees to the extent any demands made under any such
      reimbursement or similar obligation relate to a draw under the related
      letter of credit or other instrument, which draw is being contested in
      good faith by the Company through appropriate proceedings, which default
      shall have resulted in that indebtedness being accelerated without that
      indebtedness being discharged or that acceleration having been rescinded
      or annulled within five business days after the Company's receipt of the
      notice of default from the Trustee or receipt by the Company and the
      Trustee of the notice of default from the holders of not less than 25% in
      aggregate principal amount of the Debentures then outstanding, unless that
      default has been cured or waived within 30 days; and

    - certain events of bankruptcy or insolvency affecting the Company or any of
      its "significant subsidiaries" as that term is defined in Regulation S-X
      under the U.S. Securities Act, or any group or two or more subsidiaries
      that, taken as a whole, would constitute a significant subsidiary of
      the Company.

    The Indenture will provide that the Trustee will, within 30 days after the
occurrence of any continuing default known to the Trustee, mail to all holders
of the Debentures notice of all defaults of which the Trustee is aware unless
those defaults have been cured or waived by the holders before the giving of
that notice. The Trustee may withhold notice as to any default, except in the
case of a default under any of the first six bullets above, if it determines in
good faith that withholding the notice is in the interests of the holders. The
term "default" for the purpose of this paragraph means any event that is, or
after notice or lapse of time or both would become, an Event of Default with
respect to the Debentures.

    If certain events of default specified in the last bullet point above occur
and are continuing, then automatically the principal amount of the Debentures
plus accrued and unpaid interest through such date shall become immediately due
and payable without any action by the Trustee or any holder. If any other event
of default occurs and is continuing (the default not having been cured or waived
as provided under "Modification and Waiver" below), the Trustee or the holders
of at least 50% in aggregate principal amount of the Debentures then outstanding
may declare the Debentures due and payable at their principal amount plus
accrued and unpaid interest, and thereupon the Trustee may, at its discretion,
proceed to protect and enforce the rights of the holders of Debentures by
appropriate judicial proceedings. Such declaration may be rescinded or annulled
with the written consent of the holders of a majority in aggregate principal
amount of the Debentures then outstanding upon the conditions provided in
the Indenture.

    The holders of a majority in aggregate principal amount of the outstanding
Debentures may 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 provided that the direction must not be in conflict
with any law or the Indenture. In addition, the direction is subject to some
other limitations. The Trustee may refuse to perform any duty or exercise any
right or power or expend or risk its own funds or otherwise incur any financial
liability unless it receives indemnity satisfactory to it against any loss,
liability or expense. No holder of any Debenture will have any right to pursue
any remedy with respect to the Indenture or the Debentures, unless:

    - that holder has previously given the Trustee written notice of a
      continuing Event of Default;

    - the holders of at least 25% in aggregate principal amount of the
      outstanding Debentures have made a written request to the Trustee to
      pursue the relevant remedy;

    - the holder giving that written notice has, or the holders making that
      written request have, offered to the Trustee reasonable security or
      indemnity against any loss, liability or expense satisfactory to it; and

                                      S-24

    - the Trustee has failed to comply with the written request within 45 days
      after receipt of that notice, request and offer of security or indemnity.

    The right of any holder:

    - to receive payment of principal, any redemption amounts, the Debenture
      Offer Price or interest in respect of the Debentures held by that holder
      on or after the respective due dates expressed in the Debentures;

    - to convert those Debentures; or

    - to bring suit for the enforcement of any payment of principal, any
      redemption amounts, the Change of Control Purchase Price or interest in
      respect of those Debentures held by that holder on or after the respective
      due dates expressed in the Debentures, or the right to convert

will not be impaired or adversely affected without that holder's consent.

    The holders of Debentures, by extraordinary resolution, may waive any
existing default and its consequences except:

    - any default in any payment on the Debentures;

    - any default with respect to the conversion rights of the Debentures; or

    - any default in respect of the covenants or provisions in the Indenture
      that may not be modified without the consent of the holder of each
      Debenture as described in "Modification and Waiver" below.

    An "extraordinary resolution" is a resolution either passed at a meeting by
66 2/3% principal amount of Debentures represented at the meeting or a
resolution in writing signed by the holders of an aggregate 66 2/3% principal
amount of Debentures outstanding at that time.

    When a default is waived, it is deemed cured and will cease to exist, but
that waiver does not extend to any subsequent or other default or impair any
consequent right. The Company will be required to furnish to the Trustee
annually a statement as to any default by the Company in the performance and
observance of the Company's obligations under the Indenture. In addition, the
Company will be required to file with the Trustee written notice of the
occurrence of any default or Event of Default within five business days of the
Company becoming aware of the occurrence of any default or Event of Default.

MODIFICATION AND WAIVER

    The Indenture or the Debentures may not be modified or amended by the
Company without the consent of each holder affected thereby to, among
other things:

    - reduce the principal amount, Debenture Offer Price or any redemption
      amounts with respect to any Debenture, or extend the stated maturity of
      any Debenture or alter the manner of payment or rate of interest on any
      Debenture or make any Debenture payable in money or securities other than
      that stated in the Debenture;

    - make any change that adversely affects the right of a holder to convert
      any Debenture or to receive Additional Amounts with respect to
      a Debenture;

    - make any change that affects in a manner adverse to the interests of the
      holders the obligation of the Company to make a Debenture Offer;

    - impair the right to institute suit for the enforcement of any payment with
      respect to, or conversion of, the Debentures; or

    - make any change that would result in the Company being required to make
      any deduction or withholding from payments made in respect of
      the Debentures.

                                      S-25

    The Indenture or the Debentures may be modified or amended, subject to the
provisions described above, by the Company and the Trustee with the consent, by
extraordinary resolution of the Debenture holders.

    Without the consent of any holder of Debentures, the Company and the Trustee
may amend the Indenture to:

    - cure any ambiguity, defect or inconsistency, provided, however, that the
      amendment to cure any ambiguity, defect or inconsistency does not, in the
      good faith opinion of the Company's Board of Directors evidenced by a
      resolution of the Company's Board of Directors certified to the Trustee,
      materially adversely affect the rights of any holder of Debentures;

    - provide for the assumption by a successor of the Company's obligations
      under the Indenture;

    - make any change to comply with any exemption from qualification under the
      TIA, or to comply with Canadian federal or provincial legislation relating
      to trust indentures;

    - add to the Company's covenants or the Company's obligations under the
      Indenture for the protection of holders of the Debentures;

    - surrender any right, power or option conferred by the Indenture on
      the Company;

    - decrease the Conversion Price by any amount as contemplated in the
      Indenture; or

    - make any other change that does not adversely affect the rights of any
      holder of Debentures.

ADDITIONAL AMOUNTS

    The Indenture will provide that if the Company is required to make any
withholding or deduction for or on account of any Canadian taxes from any
payment made under or with respect to the Debentures, the Company will pay such
additional amounts of interest ("Additional Amounts") as may be necessary so
that the net amount received by each holder (including Additional Amounts) will
not be less than the amount the holder would have received had such Canadian
taxes not been withheld or deducted; except that no Additional Amounts will be
payable with respect to a payment made to a holder (i) with which the Company
does not deal at arm's length (within the meaning of the INCOME TAX ACT
(Canada)) at the time of making such payment, (ii) which is subject to such
Canadian taxes by reason of its being connected with Canada otherwise than by
the mere holding of the Debentures or the receipt of payments thereunder, or
(iii) which fails to comply with any administrative requirements necessary as a
precondition to exemption from Canadian withholding taxes. The Indenture also
requires the Company to provide to each holder certified copies of tax receipts
or other satisfactory evidence of the payment by the Company of the applicable
Canadian taxes within 30 days after the date of such payment.

    For a description of the exemption from Canadian withholding taxes
applicable to payments under or with respect to the Debentures, see "Income Tax
Considerations -- Certain Canadian Federal Income Tax Considerations". If, as a
result of a change to Canadian withholding tax laws, the Company has become or
would become obligated to pay, on the next date on which any amount would be
payable under or with respect to the Debentures, any Additional Amounts, the
Company may redeem all, but not less than all, the Debentures at a redemption
price equal to par plus accrued and unpaid interest to but excluding the
redemption date. See "Description of the Debentures -- Redemption -- Redemption
for Changes in Canadian Tax Law".

NOTICES

    Except as otherwise provided in the Indenture, notices to holders of
Debentures will be given by mail to the addresses of holders of the Debentures
as they appear in the securities register.

                                      S-26

REPLACEMENT OF DEBENTURES

    Any mutilated Definitive Debenture (as defined below) will be replaced by
the Company at the expense of the holder upon surrender of that Definitive
Debenture to the Trustee. Definitive Debentures that become destroyed, stolen or
lost will be replaced by the Company at the expense of the holder upon delivery
to the Trustee or evidence of the destruction, loss or theft of the Definitive
Debentures satisfactory to the Company and the Trustee. In the case of a
destroyed, lost or stolen Definitive Debenture, an indemnity and surety bond
satisfactory to the Trustee and the Company may be required at the expense of
the holder of that Definitive Debenture before a replacement Debenture will
be issued.

BOOK ENTRY, DELIVERY AND FORM

    The Debentures will be issued in the form of fully registered global
debentures (the "Global Debentures") held by, or on behalf of, CDS and, if
necessary, The Depository Trust Company, or their respective successors
(together, the "Depositories") as custodians for their participants.

    All Debentures will be represented in the form of Global Debentures
registered in the name of the Depositories or their nominees. Purchasers of
Debentures represented by Global Debentures will not receive Debentures in
definitive form. Rather, the Debentures will be represented only in book-entry
form (unless the Company, in its sole discretion, elects to prepare and deliver
definitive Debentures in fully registered form). Beneficial interests in the
Global Debentures, constituting ownership of the Debentures, will be represented
through book-entry accounts of institutions (including the Underwriters) acting
on behalf of beneficial owners, as direct and indirect participants of the
Depositories ("participants"). Each purchaser of a Debenture represented by a
Global Debenture will receive a customer confirmation of purchaser from the
Underwriter or Underwriters from whom the Debenture is purchased in accordance
with the practices and procedures of the selling Underwriters or Underwriters.
The practices of the Underwriters may vary but generally customer confirmations
are issued promptly after execution of a customer order. The Depositories will
be responsible for establishing and maintaining book-entry accounts for their
participants having interests in Global Debentures.

    If: (i) required to do so by law; (ii) the book-based system ceases to
exist; (iii) the Company determines that the Depositories are no longer willing
or able to discharge their responsibilities as depository properly and the
Company is unable to locate a qualified successor; or (iv) the Company, at its
option, elects to terminate the record entry system through the Depositories for
any reason, the Company (with the consent of the Trustee, which consents shall
not be unreasonably withheld) shall have the right to terminate the book entry
system and provide that beneficial owners of Debentures representing by Global
Debentures at such time will receive Debentures in registered and definitive
form ("Definitive Debentures").

TRANSFER AND EXCHANGE OF DEBENTURES

    Transfers of beneficial ownership in Debentures represented by Global
Debentures will be effected through records maintained by the Depositories for
such Global Debentures or their nominees (with respect to interests of
participants) and on the records of participants (with respect to interests of
persons other than participants). Unless the Company elects, in its sole
discretion, to prepare and deliver Definitive Debentures, beneficial owners who
are not participants but who desire to purchase, sell or otherwise transfer
ownership of, or other interests in, Global Debentures may do so only through
participants.

    The ability of a beneficial owner of an interest in Debentures represented
by a Global Debenture to pledge the Debenture or otherwise take action with
respect to such owner's interest in such Debenture (other than through a
participant) may be limited due to a lack of a physical certificate.

                                      S-27

    Registered holders of Definitive Debentures may only transfer such
Debentures upon payment of taxes or other charges incidental thereto, if any, by
executing and delivering a form of transfer together with such Debentures to the
Trustee at its principal offices in the Cities of Vancouver or Toronto whereupon
new Debentures will be issued in authorized denominations in the same aggregate
principal amount as the Debentures so transferred, registered in the name of the
transferee(s). No transfer of a Debenture will be registered during the period
beginning 15 days before the day of the mailing of a notice of redemption or
conversion by the Company and ending at the close of business on the day of such
mailing or during the periods commencing on any record date for the payment of
interest and ending on the next following Interest Payment Date.

PAYMENTS

    Payments of interest and principal on each Global Debenture will be made to
the Depositories or their nominees, as the case may be, as the registered holder
of the Global Debenture. As long as a Depository or its nominee is the
registered owner of a Global Debentures, such Depository or its nominee, as the
case may be, will be considered the sole legal owner of the Global Debenture for
purposes of receiving payments of interest and principal on the Debenture and
for all other purposes under the Indenture and Debenture. Interest payments may
be made by electronic funds transfer on the day interest is payable and
delivered to the Depository or its nominee.

    The Company understands that each Depository or its nominee, upon receipt of
any payment of interest or principal in respect of a Global Debenture, will
credit participants' accounts (on the date interest or principal is payable)
with payments in amounts proportionate to their respective beneficial interest
in the principal amount of such Global Debenture as shown on the records of such
Depository or its nominee. The Company also understands that payments of
interest and principal by participants to the owners of beneficial interest in
such Global Debentures will be governed by standing instructions and customary
practices, as is the case with securities held for the accounts of customers in
bearer form or registered in "street name" and will be the responsibility of
such participants. The responsibility and liability of the Company in respect of
payments on Debentures represented by Global Debentures is limited solely and
exclusively, while the Debentures are registered in Global Debenture form, to
making payment of any interest and principal due on such Global Debenture to a
Depository or its nominee.

    If Definitive Debentures are issued instead of, or in place of, Global
Debentures, payments of interest on each Definitive Debenture will be made by
electronic funds transfer, if agreed to by the holder, or by cheque dated the
Interest Payment Date and mailed to the address of the holder appearing in the
register maintained by the Trustee for the Debentures, at the close of business
on the Regular Record Date. Payment of principal at maturity will be made at the
principal office of the Trustee in the City of Vancouver (or in such other city
or cities as may from time to time be designated by the Company) against
surrender of the Definitive Debentures. If the due date for payment of any
amount of principal or interest on any Definitive Debenture is not, at the place
of payment, a business day (being a day other than a Saturday, Sunday or a day
on which financial institutions at the place of payment are authorized or
obligated by law or regulation to close) such payment will be made on the next
business day and the holder of such Definitive Debenture shall not be entitled
to any further interest or other payment in respect of such delay.

REPORTS TO HOLDERS

    The Company shall file with the Trustee and provide Holders, within 15 days
after the filing thereof with the Ontario Securities Commission and the
U.S. Securities and Exchange Commission (the "SEC"), copies of its annual
financial statements and the information, documents and other reports that the
Company is required to both (a) file with the Ontario Securities Commission or
with the SEC pursuant to Section 13(a) or 15(d) of the Exchange Act and
(b) mail to shareholders. Notwithstanding that the Company may not be required
to remain subject to the reporting requirements of the Ontario

                                      S-28

Securities Commission or the SEC, the Company shall continue to file with the
Ontario Securities Commission and the SEC, as applicable and provide to the
Trustee, and furnish to Holders without cost (a) within 140 days after the end
of each fiscal year, an annual financial statement, and (b) within 60 days after
the end of each of the first three fiscal quarters of each fiscal year, interim
financial statements which shall, at a minimum, contain such information
required to be provided in quarterly reports to security holders of a company
with securities listed on the TSX, whether or not the Company has any of its
securities so listed. Each of such reports will be prepared in accordance with
Canadian disclosure requirements and either Canadian GAAP or U.S. GAAP (whether
or not the Company is a public reporting company at the time). The Company shall
also make such reports available to prospective purchasers of the Debentures
upon their request.

GOVERNING LAW

    The Indenture and the Debentures will be governed by, and construed in
accordance with, the laws of the Province of British Columbia applicable to
contracts executed and to be performed entirely in such Province.

ENFORCEABILITY OF JUDGMENTS

    Since substantially all of the assets of the Company and its subsidiaries
are outside the United States, any judgment obtained in the United States
against the Company, including judgments with respect to amounts payable under
the Debentures, may not be collectible within the United States.

                                      S-29

                           INCOME TAX CONSIDERATIONS

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

    In the opinion of Borden Ladner Gervais LLP, counsel for the Company, and
Blake, Cassels & Graydon LLP, counsel for the underwriters, the following is a
general summary of the principal Canadian federal income tax considerations
generally applicable to a holder of Debentures (a "Holder") who acquires
Debentures under this prospectus and who, at all relevant times, for purposes of
the INCOME TAX ACT (Canada) (the "Canadian Tax Act"), holds the Debentures and
Common Shares acquired under the terms of the Debentures as capital property and
deals with the Company at arm's length. Generally, Debentures and Common Shares
will be considered to be capital property to a Holder provided that the Holder
does not hold the Debentures or Common Shares in the course of carrying on a
business and has not acquired them as an adventure in the nature of trade.
Debentures and Common Shares held by certain "financial institutions" (as
defined in the Canadian Tax Act) will generally not be capital property to such
holders and will be subject to special "mark-to-market rules" contained in the
Canadian Tax Act. This summary does not take into account these mark-to-market
rules. Holders which are financial institutions for purposes of these rules or
which otherwise do not hold their Debentures or Common Shares as capital
property should consult their own tax advisors.

    This summary is based on the current provisions of the Canadian Tax Act and
the regulations thereunder, all specific proposals to amend the Canadian
Tax Act and the regulations thereunder publicly announced by the Minister of
Finance (Canada) prior to the date hereof, and counsel's understanding of the
administrative practices of the Canada Customs and Revenue Agency (the "CCRA").
This summary is not exhaustive of all possible Canadian federal income tax
considerations and, except as mentioned above, does not anticipate any changes
in law whether by legislative, governmental or judicial decision or action, nor
does it take into account provincial, territorial or foreign tax considerations,
which may differ significantly from those discussed herein.

    THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, NOR
SHOULD IT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY PARTICULAR HOLDER AND
NO REPRESENTATION WITH RESPECT TO THE INCOME TAX CONSEQUENCES TO ANY PARTICULAR
HOLDER IS MADE. CONSEQUENTLY, PROSPECTIVE PURCHASERS OF DEBENTURES SHOULD
CONSULT THEIR OWN TAX ADVISORS FOR ADVICE WITH RESPECT TO THE TAX CONSEQUENCES
TO THEM OF HOLDING AND DISPOSING OF DEBENTURES AND COMMON SHARES ACQUIRED UNDER
THE TERMS OF THE DEBENTURES, INCLUDING THE APPLICATION AND EFFECT OF THE INCOME
AND OTHER TAX LAWS OF ANY COUNTRY, PROVINCE, STATE OR LOCAL TAX AUTHORITY.

    For purposes of the Canadian Tax Act, all amounts relating to the
acquisition, holding or disposition of Debentures or Common Shares, including
interest, dividends, adjusted cost base and proceeds of disposition, must be
converted into Canadian dollars based on the United States-Canadian dollar
exchange rate applicable to the effective date of the related acquisition,
disposition or recognition of income.

    RESIDENTS OF CANADA

    The following summary is generally applicable to a Holder who, at all
relevant times, for purposes of the Canadian Tax Act and any applicable income
tax treaty or convention, is or is deemed to be a resident of Canada. Certain
Holders whose Debentures or Common Shares acquired under the terms of the
Debentures might not otherwise qualify as capital property may make an
irrevocable election in accordance with subsection 39(4) of the Canadian
Tax Act to have the Debentures and Common Shares and every "Canadian security"
(as defined in the Canadian Tax Act) owned by such Holder in the taxation year
of the election and in all subsequent years deemed to be capital property.

                                      S-30

    TAXATION OF INTEREST ON DEBENTURES

    A Holder that is a corporation, partnership, unit trust or trust of which a
corporation or partnership is a beneficiary will be required to include in
computing its income for a taxation year any interest on a Debenture that
accrues to the Holder to the end of that taxation year or becomes receivable or
is received by it before the end of that taxation year, except to the extent
that such amount was included in the Holder's income for a preceding
taxation year.

    Any other Holder, including an individual, will be required to include in
computing income for a taxation year any interest on a Debenture received or
receivable by such Holder in that taxation year (depending upon the method
regularly followed by the Holder in computing income), except to the extent that
such amount was included in the Holder's income for a preceding taxation year.

    A Holder that is a "Canadian-controlled private corporation" (as defined in
the Canadian Tax Act) may be liable for a refundable tax of 6 2/3% on certain
investment income, including interest.

    Where a Holder is required to include in computing income, interest on
Debentures that accrued in respect of the period prior to their date of
acquisition by the Holder, the Holder will be entitled to a deduction in
computing income of an equivalent amount. The adjusted cost base to the Holder
of the Debentures will be reduced by the amount which is so deductible.

    Any amount paid by the Company as a penalty or bonus because of early
repayment of all or part of the principal amount of a Debenture will be deemed
to be interest received at that time by the Holder to the extent that such
amount can reasonably be considered to relate to, and does not exceed the value
at the time of the payment of, the interest that would have been paid or payable
by the Company on the Debenture for a period ending after the payment of
such amount.

    If the Company were to satisfy an Interest Obligation in the manner
described above under "Description of Debentures -- Share Payment
Option -- Payment of Interest" or through the issuance of shares on a conversion
as described above under "Description of the Debentures -- Conversion Rights",
the Canadian federal income tax consequences to a Holder would be unlikely to
differ from those described above.

    EXERCISE OF CONVERSION RIGHT

    A Holder that converts a Debenture into Common Shares pursuant to the
Holder's right of conversion will generally be deemed not to have disposed of
the Debenture pursuant to section 51 of the Canadian Tax Act and accordingly
will not be considered to realize a capital gain or capital loss on such
conversion. The cost to such Holder of the Common Shares acquired on the
conversion will be equal to the Holder's adjusted cost base of the Debenture
immediately before the conversion. The adjusted cost base to the Holder of the
Common Shares acquired on the conversion will be averaged with the adjusted cost
base of all other Common Shares held by the Holder as capital property.

    Under the current administrative practice of the CCRA, a Holder who, upon
conversion of a Debenture, receives an amount not in excess of $200 in lieu of a
fraction of a Common Share may either treat this amount as proceeds of
disposition of a portion of a Debenture, thereby realizing a capital gain or
capital loss, or alternatively may reduce the adjusted cost base of the Common
Shares that the Holder receives on the conversion by the amount of cash
received. If the cash consideration exceeds $200, the Holder must treat the
amount as proceeds of disposition of a portion of a Debenture, thereby realizing
a capital gain or capital loss.

    REDEMPTION OR REPAYMENT OF DEBENTURES

    If the Company satisfies its obligations under a Debenture by issuing Common
Shares to the Holder and making any cash payment in lieu of a fraction of a
Common Share as described above

                                      S-31

under "Description of Debentures -- Share Repayment Option -- Payment of
Principal at Maturity or on Redemption" and the Holder does not exercise the
conversion privilege prior to such redemption or repayment, the Holder's
proceeds of disposition of the Debenture will be equal to the fair market value
of the Common Shares (other than Common Shares received in satisfaction of
accrued interest) and cash so received, so that the Holder may realize a capital
gain or capital loss on the disposition of the Debenture. The cost to the Holder
of Common Shares so received will be equal to the fair market value of such
Common Shares. The adjusted cost base to the Holder of Common Shares so received
will be averaged with the adjusted cost base of all other Common Shares held by
the Holder as capital property.

    OTHER DISPOSITIONS OF DEBENTURES

    A disposition or deemed disposition of a Debenture will generally give rise
to a capital gain (or capital loss) to the extent that the Holder's proceeds of
disposition (adjusted as described below), net of any reasonable costs of
disposition, exceed (or are less than) the adjusted cost base of the Debenture
to the Holder immediately before the disposition.

    Upon such a disposition or deemed disposition of a Debenture, a Holder will
generally also be required to include in computing income the amount of interest
accrued on the Debenture from the date of the last interest payment to the date
of disposition to the extent that such amount has not otherwise been included in
computing the Holder's income for the taxation year or a previous taxation year.
A Holder's proceeds of disposition will then be reduced by this amount.

    CAPITAL GAINS OR LOSSES REALIZED ON DISPOSITIONS OF DEBENTURES

    One-half of the amount of any capital gain (a "taxable capital gain")
realized by a Holder in a taxation year must be included in computing the
Holder's income in that year. One-half of the amount of any capital loss (an
"allowable capital loss") realized by a Holder in a taxation year generally may
be deducted from taxable capital gains realized by the Holder in that year.
Allowable capital losses in excess of taxable capital gains may be carried back
and deducted in any of the three preceding taxation years or carried forward and
deducted in any following taxation year against taxable capital gains realized
in such years to the extent and under the circumstances described in the
Canadian Tax Act.

    A capital gain realized by an individual may give rise to a liability for
alternative minimum tax. A Holder that is a "Canadian-controlled private
corporation" (as defined in the Canadian Tax Act) may be liable for a refundable
tax of 6 2/3% on certain investment income, including taxable capital gains.

    COMMON SHARES

    Dividends declared and paid on a Holder's Common Shares will be included in
the Holder's income as taxable dividends received from a taxable Canadian
corporation. The normal gross-up and dividend tax credit rules will apply to
dividends received by a Holder who is an individual and dividends received by a
Holder which is a corporation will normally be deductible in computing its
taxable income. Certain corporations may be liable to pay a refundable tax under
Part IV of the Canadian Tax Act on such dividends.

    A disposition or deemed disposition of a Common Share will generally result
in the Holder realizing a capital gain (or capital loss) to the extent that the
proceeds of disposition of the Common Share exceed (or are less than) the
aggregate of the Holder's adjusted cost base of the Common Share and any
reasonable costs related to the disposition. The general tax treatment of
capital gains and capital losses is discussed above under the heading "Residents
of Canada -- Capital Gains or Losses Realized on Dispositions of Debentures".

                                      S-32

    In the case of a Holder that is a corporation, the amount of any capital
loss otherwise determined resulting from the disposition or deemed disposition
of a Common Share may be reduced by the amount of dividends previously received
or deemed to have been received thereon in accordance with detailed rules
contained in the Canadian Tax Act in this regard. Analogous rules apply where a
corporation is a member of a partnership or a beneficiary of a trust that owns
Common Shares or where a partnership or trust, of which a corporation is a
member or beneficiary, itself is a member of a partnership or a beneficiary of a
trust that owns Common Shares. Holders to whom these rules may be relevant
should consult their own tax advisors.

    NON-RESIDENTS OF CANADA

    The following summary is generally applicable to a Holder who, at all
relevant times, for purposes of the Canadian Tax Act and any applicable income
tax treaty or convention, is or is deemed to be a non-resident of Canada and
does not use or hold and is not deemed to use or hold the Debentures or Common
Shares acquired under the terms of the Debentures in carrying on a business in
Canada (a "Non-Resident Holder"). Special rules, which are not discussed below,
may apply to a Non-Resident Holder which is an insurer that carries on business
in Canada and elsewhere.

    The term "US Holder," for the purposes of this summary, means a Non-Resident
Holder who, for purposes of the Canada-United States Income Tax Convention
(1980) (the "Convention"), is at all relevant times a resident of the
United States and does not use or hold and is not deemed to use or hold the
Debentures or the Common Shares in connection with carrying on a business in
Canada through a permanent establishment or fixed base in Canada.

    TAXATION OF INTEREST ON DEBENTURES

    A Non-Resident Holder will not be subject to Canadian withholding tax in
respect of amounts paid or credited by the Company as, on account or in lieu of
payment of, or in satisfaction of, the principal of the Debentures or interest
thereon including in respect of a payment of a Change of Control
Purchase Price.

    EXERCISE OF CONVERSION RIGHT

    The conversion of a Debenture into Common Shares pursuant to a Non-Resident
Holder's right of conversion will generally be deemed not to constitute a
disposition of the Debenture pursuant to section 51 of the Canadian Tax Act and,
accordingly, the Non-Resident Holder will not realize a capital gain or capital
loss on such conversion.

    DISPOSITION OF DEBENTURES AND COMMON SHARES

    A Non-Resident Holder will not be subject to tax under the Canadian Tax Act
in respect of any capital gain realized by such Non-Resident Holder on a
disposition of a Debenture or a Common Share acquired under the terms of the
Debentures, as the case may be, unless the Debenture or Common Share constitutes
"taxable Canadian property" (as defined in the Canadian Tax Act) of the
Non-Resident Holder at the time of disposition and the Holder is not entitled to
relief under an applicable income tax treaty or convention. As long as the
Common Shares are then listed on a prescribed stock exchange (which currently
includes the TSX and Nasdaq), the Debentures and the Common Shares generally
will not constitute taxable Canadian property of a Non-Resident Holder, unless
at any time during the 60-month period immediately preceding the disposition the
Non-Resident Holder, persons with whom the Non-Resident Holder did not deal at
arm's length, or the Non-Resident Holder together with all such persons, owned
or was considered to own 25% or more of the issued shares of any class or series
of shares of the capital stock of the Company. In this case, both

                                      S-33

the Debentures and the Common Shares will constitute taxable Canadian property
to the Non-Resident Holder.

    If the Debentures or the Common Shares are taxable Canadian property to a
Non-Resident Holder that is a US Holder at the time of disposition, any capital
gain realized on the disposition or deemed disposition of such Debentures or
Common Shares will, according to the Convention, generally not be subject to
Canadian federal income tax unless the value of the shares of the Company at the
time of the disposition of the Debentures or Common Shares is derived
principally from "real estate situated in Canada" within the meaning set out in
the Convention. A Non-Resident Holder whose Debentures or Common Shares are
taxable Canadian property should consult their own advisors.

    TAXATION OF DIVIDENDS ON COMMON SHARES

    Under the Canadian Tax Act, dividends on Common Shares paid or credited to a
Non-Resident Holder will be subject to Canadian withholding tax at the rate of
25% of the gross amount of the dividends. This withholding tax may be reduced
pursuant to the terms of an applicable income tax treaty or convention between
Canada and the country of residence of a Non-Resident Holder. Under the
Convention, a Non-Resident Holder that is a US Holder will generally be subject
to Canadian withholding tax at a rate of 15% of the amount of such dividends. In
addition, under the Convention, dividends may be exempt from Canadian
non-resident withholding tax if paid to certain US Holders that are qualifying
religious, scientific, literary, educational or charitable tax-exempt
organizations and qualifying trusts, companies, organizations or arrangements
operated exclusively to administer or provide pension, retirement or employee
benefits that are exempt from tax in the United States and that have complied
with specific administrative procedures.

CERTAIN MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

    The following summary describes certain material United States federal
income tax consequences of the ownership, disposition and conversion of the
Debentures and the Common Shares into which Debentures may be converted, to
U.S. Holders, defined below, who purchase Debentures at the initial price
pursuant to the offering, and does not address any tax considerations applicable
to subsequent purchasers of the Debentures. This summary is based upon the
provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
applicable Treasury Regulations promulgated and proposed thereunder, judicial
authority and administrative interpretations of the foregoing, all of which are
subject to change, possibly on a retroactive basis. This summary applies only to
U.S. Holders that hold Debentures (and Common Shares into which Debentures may
be converted) as "capital assets" within the meaning of Section 1221 of the
Code. This discussion does not address all of the tax considerations that may be
applicable to a U.S. Holder's particular circumstances or to U.S. Holders that
may be subject to special tax rules such as banks, holders subject to the
alternative minimum tax, tax-exempt organizations, persons that have a
functional currency other than the U.S. dollar, persons holding Debentures or
Common Shares in a tax-deferred or tax-advantaged account, persons who are
partners, shareholders or beneficiaries of an entity that holds the Debentures
or Common Shares, insurance companies, non-United States persons or entities,
dealers in securities or currencies, persons that will hold Debentures as a
position in a hedging transaction, "straddle" or "conversion transaction" for
tax purposes, persons deemed to sell Debentures or Common Shares under the
constructive sale provisions of the Code, or persons who actually or
constructively own 10% or more of the Common Shares. This summary does not
consider the effect of the United States federal estate or gift tax laws or the
tax laws of any applicable foreign, state, local or other jurisdiction.

    For purposes of this summary, "U.S. Holders" includes: (i) individual
citizens or residents of the United States, (ii) corporations or other entities
taxable as corporations that are created or organized in or under the laws of
the United States or of any political subdivision thereof; (iii) estates, the
incomes of which are subject to United States federal income taxation regardless
of the source of such

                                      S-34

income; or (iv) trusts subject to the primary supervision of a United States
court and the control of one or more United States persons or trusts that have
elected to be treated as United States persons under applicable Treasury
Regulations.

    The Company has not sought any ruling from the Internal Revenue Service with
respect to the statements made and the conclusions reached in the following
summary. Accordingly, there can be no assurance that the IRS will not challenge
such statements and conclusions or that a court will not sustain such a
challenge.

    INVESTORS CONSIDERING THE PURCHASE OF DEBENTURES SHOULD CONSULT THEIR OWN
TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE UNITED STATES FEDERAL INCOME
TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING
UNDER THE UNITED STATES FEDERAL ESTATE OR GIFT TAX RULES OR UNDER THE LAWS OF
ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX
TREATY.

    TAXATION OF INTEREST

    Interest paid on the Debentures (including any Canadian taxes withheld
therefrom and any additional amounts paid) will be included in the income of a
U.S. Holder as ordinary income at the time it is treated as received or accrued,
in accordance with such U.S. Holder's regular method of accounting for
United States federal income tax purposes. Such interest will be treated as
income from outside the United States, and generally will be treated as "passive
income" or "financial services income", for United States foreign tax credit
purposes. A U.S. Holder may be entitled to a United States foreign tax credit or
a deduction for any Canadian taxes withheld, although the amount of such credit
or deduction may be limited by the Code. The Code applies various limitations on
the amount of foreign taxes that may be claimed as a credit by U.S. taxpayers.
Because of the complexity of those limitations, U.S. Holders should consult
their own tax advisors with respect to the amount of foreign taxes that can be
claimed as a credit. Alternatively, a U.S. Holder may be entitled to a deduction
for foreign taxes.

    In certain circumstances, the Company may be obligated to pay a holder
amounts in excess of stated interest and principal on the Debentures. For
example, a holder may require the Company to redeem any and all of his or her
Debentures for an amount equal to 101% of the principal amount plus accrued and
unpaid interest in the event of a Change of Control. Under Treasury Regulations,
the possibility of an additional payment under a Debenture may be disregarded
for purposes of determining the amount of interest or original issue discount
income to be recognized by a holder in respect of such instrument (or the timing
of such recognition) if the likelihood of the payment, as of the date the
Debentures are issued, is remote. The Company believes that the likelihood of a
payment with respect to the Debentures as a result of a "Change of Control", or
any other payment in excess of stated interest and principal, is remote and does
not intend to treat these possibilities as affecting the yield to maturity of
any Debenture. The Company's determination that this likelihood is remote is
binding on a U.S. Holder unless the U.S. Holder discloses a contrary position in
a timely filed tax return for the taxable year in which the U.S. Holder acquires
the Debenture. In the event any such contingency occurs, it could affect the
amount and timing of the income that must be recognized by a U.S. Holder of
Debentures. There can be no assurance that the IRS will agree with the position
taken by the Company.

    SALE, EXCHANGE OR REDEMPTION OF THE DEBENTURES

    Upon the sale, exchange (other than a conversion) or redemption of a
Debenture, a U.S. Holder generally will recognize capital gain or loss equal to
the difference between (i) the amount of cash proceeds and the fair market value
of any property received on the sale, exchange or redemption

                                      S-35

(except to the extent such amount is attributable to accrued interest income not
previously included in income, which will be taxable as ordinary income, or is
attributable to accrued interest that was previously included in income, which
amount may be received without generating further income) and (ii) such
U.S. Holder's adjusted tax basis in the Debenture. A U.S. Holder's adjusted tax
basis in a Debenture generally will equal the cost of the Debenture to such
U.S. Holder, less any principal payments received by the U.S. Holder. Such
capital gain or loss will be long-term capital gain or loss if the
U.S. Holder's holding period in the Debentures is more than one year at the time
of sale, exchange or redemption. The deductibility of capital losses is subject
to limitations. Such gain or loss generally will be treated as income or loss
from within the United States for United States foreign tax credit purposes.

    ADJUSTMENTS IN THE CONVERSION PRICE OF THE DEBENTURES

    The conversion price of the Debentures is subject to adjustment under
certain circumstances. Under Section 305 of the Code and the Treasury
Regulations issued thereunder, there may be a taxable constructive distribution
to U.S. Holders, resulting in ordinary income to the extent of the Company's
current and accumulated earnings and profits (as determined under United States
federal income tax principles), if, and to the extent that, certain adjustments
in the conversion price increase such U.S. Holder's proportionate interest in
the earnings and profits and assets of the Company. Such adjustment may occur in
limited circumstances (particularly an adjustment to reflect a taxable dividend
distribution with respect to the Common Shares) and in such case a constructive
distribution would arise, whether or not the U.S. Holders ever convert the
Debentures. Generally, a U.S. Holder's tax basis in a Debenture will be
increased by the amount of any such constructive distribution.

    CONVERSION OF THE DEBENTURES

    A U.S. Holder generally will not recognize any income, gain or loss upon
conversion of a Debenture into Common Shares except with respect to (i) cash
received in lieu of a fractional Common Share and (ii) any payments (including
the receipt of Common Shares) in respect of accrued but unpaid interest. A
U.S. Holder's tax basis in the Common Shares received on conversion of a
Debenture will be the same as such U.S. Holder's adjusted tax basis in the
Debenture at the time of conversion (reduced by any basis allocable to a
fractional share interest), and the holding period for the Common Shares
received on conversion will generally include the holding period of the
Debenture converted. However, a U.S. Holder's tax basis in Common Shares
considered attributable to accrued interest generally will equal the amount of
such accrued interest included in income, and the holding period for such shares
will begin on the date of conversion.

    Cash received in lieu of a fractional Common Share upon conversion will be
treated as a payment in exchange for the fractional Common Share. Accordingly,
the receipt of cash in lieu of a fractional Common Share generally will result
in capital gain or loss (measured by the difference between the cash received
for the fractional share and the holder's adjusted tax basis in the fractional
Common Share).

    SALE OF COMMON SHARES

    Subject to the passive foreign investment company ("PFIC") rules discussed
below, upon the sale or exchange of Common Shares a U.S. Holder generally will
recognize capital gain or loss equal to the difference between (i) the amount of
cash proceeds and the fair market value of any property received upon the sale
or exchange and (ii) such U.S. Holder's adjusted tax basis in the Common Shares.
Such capital gain or loss will be long-term capital gain or loss if the
U.S. Holder's holding period in the Common Shares is more than one year at the
time of the sale or exchange. A U.S. Holder's basis and holding period in Common
Shares received upon conversion of a Debenture are determined as discussed above
under "Conversion of the Debentures". The deductibility of capital losses is
subject to

                                      S-36

limitations. Such gain or loss generally will be treated as income or loss from
within the United States for United States foreign tax credit purposes.

    DIVIDENDS

    Subject to the PFIC rules discussed below, distributions (including any
Canadian taxes withheld therefrom), if any, made on the Common Shares after a
conversion generally will be included in the income of a U.S. Holder as ordinary
dividend income to the extent of the Company's current and accumulated earnings
and profits, as determined under United States federal income tax principles. A
corporate U.S. Holder will not be entitled to a dividends received deduction
generally available upon the receipt of dividends distributed by United States
corporations. Distributions in excess of the Company's current and accumulated
earnings and profits will be treated as a return of capital to the extent of the
U.S. Holder's basis in the Common Shares and thereafter as capital gain.
Dividends will be treated as income from outside the United States, but
generally will be treated as "passive income" or "financial services income",
for United States foreign tax credit purposes. A U.S. Holder may be entitled to
a United States foreign tax credit or deduction for any Canadian tax withheld,
although the amount of such credit or deduction may be limited by the Code.

    PAYMENTS IN CANADIAN DOLLARS

    If any dividends are paid in a currency other than the U.S. dollar, the
amount includible in gross income will be the U.S. dollar value of such
dividend, calculated by reference to the exchange rate in effect on the date of
receipt of the payment, regardless of whether the payment is actually converted
into U.S. dollars. If any Canadian dollars received are later converted into
U.S. dollars, U.S. Holders may realize gain or loss on the conversion. Gain or
loss, if any, realized as a result of currency exchange fluctuations during the
period from the date of inclusion of the payment in income to the date of
conversion of the payment into U.S. dollars will be treated as ordinary income
or loss. This gain or loss generally will be from sources within the
United States for United States foreign tax credit purposes. U.S. Holders should
consult their own tax advisors concerning the possibility of foreign currency
gain or loss if any such currency is not converted into U.S. dollars on the date
of receipt.

    PASSIVE FOREIGN INVESTMENT COMPANY STATUS

    Special United States federal income tax rules apply to United States
persons owning shares of a PFIC. As described below, the Company does not
believe that it currently is a PFIC, nor does the Company anticipate becoming a
PFIC in the foreseeable future. However, there can be no assurance that the IRS
will not successfully challenge the Company's position or that the Company will
not become a PFIC at some future time as a result of changes in its assets,
income or business operations.

    A non-U.S. corporation generally will be classified as a PFIC for
United States federal income tax purposes in any taxable year in which, after
applying relevant look-through rules with respect to the income and assets of
subsidiaries, either at least 75% of its gross income is "passive income", or on
average at least 50% of the gross value of its assets is attributable to assets
that produce passive income or are held for the production of passive income.
For this purpose, passive income generally includes, among other things,
dividends, interest, certain rents and royalties and gains from the disposition
of passive assets. Net gains from commodities transactions are generally treated
as passive income, potentially triggering PFIC status, unless derived in the
active conduct of business as a producer, processor, merchant or handler of
commodities where a corporation's gross receipts from such qualified activities
exceed 85% of its total gross receipts.

    If the Company is classified as a PFIC for any taxable year during which a
U.S. Holder holds Common Shares or Debentures, such U.S. Holder generally will
be taxed at ordinary income tax rates on any gain realized on the sale or
exchange of the Common Shares or Debentures and will also be

                                      S-37

subject to a special interest charge with respect to any such gain and certain
dividends received. Rather than being subject to this tax regime, a U.S. Holder
of Common Shares may:

    - make a "qualified electing fund" election, as defined in the Code, to be
      taxed currently on its pro rata portion of the Company's income and gain,
      whether or not such income or gain is distributed in the form of dividends
      or otherwise, or

    - make a "mark-to-market" election and thereby agree, for the year of the
      election and each subsequent tax year, to recognize ordinary gain or, to
      the extent of prior ordinary gain, ordinary loss based on the increase or
      decrease in market value for such taxable year. The U.S. Holder of Common
      Shares' basis in its Common Shares would be adjusted to reflect any such
      income or loss amounts.

    A U.S. Holder of Debentures will not be eligible to make a "qualified
electing fund" election while the U.S. Holder holds Debentures and therefore
will be unable to make a timely election. It is unclear whether a U.S. Holder of
Debentures will be eligible to make a "mark-to-market" election. U.S. Holders of
Debentures should consult their own tax advisors regarding the federal income
tax consequences that would arise if the Company were treated as a PFIC while a
U.S. Holder held Debentures.

    BACKUP WITHHOLDING TAX

    A "backup" withholding tax may apply to certain payments of principal and
interest and dividends as well as proceeds from a sale or exchange of Debentures
or Common Shares made to certain non-corporate U.S. Holders if certain
information reporting requirements are not met. Backup withholding tax, if any,
would be credited against a U.S. Holder's United States federal income tax
liability. U.S. Holders should consult their own tax advisors as to their
qualification for exemption from any backup withholding tax and the procedure
for obtaining such exemption.

    THE PRECEDING DISCUSSION OF CERTAIN UNITED STATES FEDERAL INCOME TAX
CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE.
ACCORDINGLY, EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS TAX ADVISOR AS TO THE
PARTICULAR UNITED STATES FEDERAL, STATE, AND LOCAL TAX CONSEQUENCES OF
PURCHASING, HOLDING AND DISPOSING OF THE DEBENTURES AND COMMON SHARES. TAX
ADVISORS SHOULD ALSO BE CONSULTED AS TO THE UNITED STATES ESTATE AND GIFT TAX
CONSEQUENCES AND THE FOREIGN TAX CONSEQUENCES OF PURCHASING, HOLDING AND
DISPOSING OF THE DEBENTURES AND COMMON SHARES AS WELL AS THE CONSEQUENCES UNDER
THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION OR UNDER ANY
APPLICABLE TAX TREATY.

                                USE OF PROCEEDS

    The estimated net proceeds to the Company from the sale of the Debentures
offered hereby, after payment of the Underwriters' fee and the estimated
expenses of this Offering, will be US$72,350,000 or, if the Over-Allotment
Option is exercised in full, US$83,262,500. The net proceeds from the sale of
the Debentures will be used by the Company to fund development of the Alamo
Dorado project, future capital, development and exploration programs, working
capital requirements and for other general corporate purposes. Pending the uses
described above, the Company may invest all or a portion of the net proceeds
derived from the sale of the Debentures in short-term interest bearing
securities.

    There may be circumstances where, for business reasons, a reallocation of
the proceeds from the sale of Debentures offered by this prospectus supplement
may be necessary. The Company will only redirect such proceeds to its other
properties and will do so only on the basis of a written recommendation from an
independent, professional geologist or engineer.

                              PLAN OF DISTRIBUTION

    Pursuant to an agreement (the "Underwriting Agreement") dated July 21, 2003,
among the Company and the Underwriters, the Company has agreed to sell and the
Underwriters have severally agreed to purchase on or about July 30, 2003, but in
any event not later than August 31, 2003, all but not less than all of the
US$75,000,000 principal amount of Debentures for an aggregate price of
$75,000,000. The Underwriters will be paid an aggregate commission of $2,250,000
for their services rendered in connection with this Offering, which will be paid
out of the general funds of the Company.

    The obligations of the Underwriters under the Underwriting Agreement are
several and not joint and may be terminated upon the occurrence of certain
stated events. The Underwriters are, however, obligated to take up and pay for
all of the Debentures if any of such Debentures are purchased under the
Underwriting Agreement.

    The Company has granted the Underwriters an option to purchase additional
Debentures up to a maximum of $11,250,000 to cover over-allotments (the
"Over-Allotment Option"). The Underwriters may exercise the Over-Allotment
Option in whole or in part at any time on or before the close of business on the
30th day following the closing of this Offering for the purposes of covering
over-allotments, if any. To the extent that the Over-Allotment Option is
exercised, the additional Debentures will be purchased by the Underwriters for
the principal amount of the Debentures, plus accrued interest, if any, from
July 30, 2003 to the closing date of the issuance of Debentures pursuant to the
Over-Allotment Option, and otherwise on the same terms. If the Over-Allotment
Option is exercised in full, the total aggregate underwriting commission to be
paid to the Underwriters will be US$2,587,500. This prospectus supplement
qualifies the distribution of the Debentures to be issued on exercise of the
Over-Allotment Option.

    The Company has agreed to indemnify the Underwriters and their directors,
officers, employees and agents against certain liabilities, including civil
liabilities under the United States Securities Act of 1933, as amended (the
"U.S. Securities Act"), and applicable Canadian securities legislation, or to
contribute to any payments the Underwriters may be required to make in respect
thereof.

    Subscriptions for Debentures offered hereby will be received subject to
rejection or allotment in whole or in part and the right is reserved to close
the subscription books at any time without notice.

    Pursuant to policy statements of the Ontario Securities Commission, the
Underwriters may not, throughout the period of distribution under this
prospectus, bid for or purchase Debentures or Common Shares. The foregoing
restriction is subject to certain exceptions, as long as the bid or purchase is
not engaged in for the purpose of creating actual or apparent active trading in
or raising the price of such securities. These exceptions include a bid or
purchase permitted under the by-laws and rules of the TSX as well as applicable
rules of Regulation M under the U.S. Securities Act, relating

                                      S-39

to market stabilization and passive market making activities and a bid or
purchase made for and on behalf of a customer where the order was not solicited
during the period of distribution. Subject to the foregoing and applicable laws,
the Underwriters may, in connection with this Offering, over-allot or effect
transactions which stabilize or maintain the market price of the Debentures at
levels other than those which otherwise might prevail on the open market. Such
transactions, if commenced, may be discontinued at any time.

    The terms of the Offering, including the offering price of the Debentures,
was determined by negotiation between the Company and the Underwriters.

    The Offering will be made concurrently in the provinces of British Columbia,
Alberta, Manitoba and Ontario and in the United States pursuant to the
multijurisdictional disclosure system implemented by securities regulatory
authorities in Canada and the United States. Any sales in the United States will
be made through United States registered broker-dealer affiliates of the
Underwriters.

    The Debentures are a newly-listed security with no established trading
market. The TSX has conditionally approved the listing of the Debentures and the
Common Shares issuable upon the conversion of the Debentures. The Company has
notified NASDAQ of the proposed issuance of the Debentures and the Common Shares
issuable upon conversion of the Debentures. There is no current intention to
list the Debentures on NASDAQ.

    The Company has agreed in the Underwriting Agreement that it will not
(subject to certain exceptions) issue or agree to issue any equity securities or
other securities convertible into equity securities until 90 days from closing
of the Offering, without the prior consent of BMO Nesbitt Burns Inc.

                     TRUSTEE, TRANSFER AGENT AND REGISTRAR

    The trustee under the Indenture and the registrar and transfer agent for the
Common Shares is Computershare Trust Company of Canada through its offices in
Vancouver and Toronto.

                                 LEGAL MATTERS

    Certain Canadian and U.S. legal matters relating to the Debentures offered
hereby will be passed upon for the Company by Borden Ladner Gervais LLP and
Skadden, Arps, Slate, Meagher & Flom LLP, respectively, and for the Underwriters
by Blake, Cassels & Graydon LLP and Shearman & Sterling LLP, respectively. As of
the date of this prospectus supplement, the partners and associates of Borden
Ladner Gervais LLP and Blake, Cassels & Graydon LLP, collectively, beneficially
own less than 1% of the outstanding Debentures or Common Shares of the Company.

    The Company may offer and sell Securities to or through underwriters or
dealers, directly to one or more purchasers pursuant to applicable statutory
exemptions, or through agents designated from time to time. The Prospectus
Supplement relating to a particular offering of Securities will identify each

Securities and will set forth the plan of distribution for such Securities,
including the proceeds to the Company and any fees, discounts, concessions or
other compensation payable to the underwriters, dealers or agents, and any other
material terms of the plan of distribution.

    The Common Shares of the Company are listed on the Toronto Stock Exchange

                                  THE COMPANY

    Pan American Silver Corp. is a company incorporated under the COMPANY ACT
(British Columbia). The Company's head office is located at 1500 - 625 Howe
Street, Vancouver, British Columbia, V6C 2T6 and its registered and records
office is located at 900 Waterfront Centre, 200 Burrard Street, Vancouver,
British Columbia, V7X 1T2. In this Prospectus, the term "Pan American" refers to
the Company and its principal subsidiaries.

    A description of the Company's principal subsidiaries as at its most recent
financial year end is set out under the heading "Subsidiaries" on page 3 of the
Company's annual information form which is incorporated by reference in this
Prospectus.

                            BUSINESS OF THE COMPANY

    Pan American is principally engaged in the exploration for, and the
acquisition, development and operation of silver properties.

    Pan American: (i) owns and operates the producing Quiruvilca silver mine in
Peru; (ii) owns and operates the producing Huaron silver mine in Peru;
(iii) owns and operates the producing La Colorada silver mine and development
project located in Mexico (Pan American completed a significant expansion of the
La Colorada mine in June of 2003 and silver production is expected to increase
over the balance of 2003); and (iv) mines and sells silver-rich pyrite
stockpiles at a small-scale operation in central Peru. Pan American also either
holds an interest in or may earn an interest in non-producing silver resource
and silver exploration properties in Peru, Argentina, the United States, Russia
and Mexico, including the significant Alamo Dorado deposit in Mexico on which
the Company is preparing a feasibility study.

                              RECENT DEVELOPMENTS

    In July of 2003, Pan American initiated a technical and economic evaluation
of a possible expansion of the Huaron mine in Peru, which would increase this
mine's production.

    Pan American substantially completed a major expansion at its La Colorada
silver mine in Mexico during June of 2003. The expansion included the
construction of a 600 tonne per day oxide mill, which will add to the mine's
current production from the existing 200 tonne per day sulphide mill. Production
is expected to reach design capacity within a few months following the end of
June of 2003. The expansion was completed ahead of schedule and approximately 5%
under the original US$20 million budget.

    A 6,000 metre infill drilling program has been completed on Pan American's
50%-owned Manantial Espejo silver-gold exploration property in Argentina. The
results have confirmed the size of the deposit and increased Pan American's
confidence in its geological model, leading Pan American and its joint venture
partner, Silver Standard Resources Inc., to accelerate the commissioning of a
feasibility study on the property. The study will be initiated in the fourth
quarter of 2003 for completion in the fall of 2004. Over the remainder of 2003,
geotechnical and environmental work will proceed on the project to facilitate
permitting.

    On February 20, 2003, the Company acquired all of the issued and outstanding
shares of Corner Bay Silver Inc. ("Corner Bay") pursuant to a plan of
arrangement under the Canada Business Corporations Act. Under this plan of
arrangement, each Corner Bay share was exchanged for 0.3846 Common Shares of the
Company plus 0.1923 warrants of the Company, resulting in the issuance of a
total of 7,636,659 Common Shares and 3,818,330 warrants of the Company. Each
whole warrant will allow the holder to purchase one Common Share of the Company
for a price of Cdn$12.00 at any time over a five-year exercise period. Pan
American also issued options to purchase up to 553,846 Common Shares (having
exercise prices of between Cdn$4.55 and Cdn$12.00 and having exercise periods of

                                       7

between one and five years from the date of grant) in consideration for the
termination of 960,000 fully vested stock options held by employees and
shareholders of Corner Bay. Corner Bay, through its subsidiary corporations,
owns the Alamo Dorado silver-gold deposit in Mexico. The Alamo Dorado project is
described under the heading "Narrative Description of the
Business -- Development Projects -- Alamo Dorado Project" on pages 32
through 38 of the Company's annual information form which is incorporated by
reference in this Prospectus.

    In May of 2003, Pan American completed a seven-hole drill program on the
Alamo Dorado project and is undertaking metallurgical testing to update a 2002
feasibility study completed by AMEC E&C Services, Inc. The updated feasibility
study will examine the economic merits of processing ore from the Alamo Dorado
deposit in a conventional oxide leaching mill circuit versus heap leach
processing. The update will also examine the economic merits of a combination
mill for high grade ore and heap leach for low grade ore. The updated study is
expected to be completed in the fourth quarter of 2003. Until this study is
completed and a production decision made, the acquisition of Corner Bay and the
Alamo Dorado project is not expected to have any material effect on the
operating results and financial position of Pan American.

                                USE OF PROCEEDS

    Unless otherwise indicated in the applicable Prospectus Supplement, the net
proceeds from the sale of Securities will be used by the Company to fund
development of the Alamo Dorado project, the expansion of the Huaron mine, other
ongoing development and exploration programs and working capital requirements
and for other general corporate purposes. The Company may, from time to time,
issue Common Shares and other securities otherwise than through the offering of
Securities pursuant to this Prospectus.

                               EARNINGS COVERAGE

    The following consolidated financial earnings deficiency figures and cash
flow coverage ratios are calculated for the year ended December 31, 2002 and the
12-month period ended March 31, 2003 and give effect to all long-term financial
liabilities of Pan American and the repayment, redemption or retirement thereof
since those dates, respectively. The earnings coverage deficiencies, cash flow
ratios and the amount of earnings, cash flow and interest expense set forth
below do not purport to be indicative of earnings coverage deficiencies or
ratios or cash flow coverage ratios for any future periods. The deficiency
figures and coverage ratios have been calculated based on Canadian GAAP. These
coverage deficiencies, coverage ratios, earnings, cash flow or interest expense
do not give effect to the issuance of any Debt Securities that may be issued
pursuant to this Prospectus and any Prospectus Supplement, since the aggregate
principal amounts and the terms of such Debt Securities are not presently known.



                                                                  YEAR ENDED       12 MONTHS ENDED

                                                              ------------------   ---------------
                                                                             
Earnings coverage deficiency(1).............................     $(33,658,000)      $(33,699,000)
Earnings coverage deficiency before unusual items(2)........     $ (6,440,000)      $ (7,247,000)
Cash flow coverage/(deficiency)(3)(4).......................             7.94(3)    $ (7,360,000)(4)


------------------------

(1) Earnings coverage deficiency is the dollar amount of earnings required to
    attain an earnings coverage ratio of one-to-one. Earnings coverage ratio is
    equal to net income before interest expense and income taxes divided by
    interest expense on all debt.

(2) Earnings coverage deficiency before unusual items is the dollar amount of
    earnings required to attain an earnings coverage ratio before unusual items
    of one-to-one. Earnings coverage ratio before unusual items is equal to net
    income before interest expense, income taxes and write-down of the Company's
    investment in the Quiruvilca mine and accrual for future reclamation costs
    for the Quiruvilca Mine divided by interest expense on all debt.

(3) Cash flow coverage is equal to cash flow from operating, financing and
    investment activities before interest expense and income taxes divided by
    interest expense on all debt.

(4) Cash flow deficiency is the dollar amount of cash flow required to attain a
    cash flow coverage ratio of one-to-one. Cash flow coverage ratio is equal to
    cash flow from operating, financing and investment activities before
    interest expense and income taxes divided by interest expense on all debt.

    The Company's interest expense requirements amounted to approximately
$988,000 for the year ended December 31, 2002. The Company's losses before
interest expense and income tax for the year ended December 31, 2002 were
approximately $32,670,000, which is a deficiency of approximately $33,658,000 of
the earnings amount necessary to attain a earnings coverage ratio of one-to-one
for this period.

    The Company's interest expense requirements amounted to approximately
$881,000 for the 12 months ended March 31, 2003. The Company's losses before
interest expense and income tax for the 12 months ended March 31, 2003 were
approximately $32,818,000, which is a deficiency of approximately $33,699,000 of
the earnings amount necessary to attain a earnings coverage ratio of one-to-one
for this period.

    If the Company offers any Debt Securities having a term to maturity in
excess of one year under this Prospectus and a Prospectus Supplement, the
Prospectus Supplement will include earnings coverage ratios giving effect to the
issuance of such Debt Securities.

                          DESCRIPTION OF SHARE CAPITAL

    The Company is authorized to issue 100,000,000 Common Shares, without par
value, of which 52,127,284 are issued and outstanding as at the date of this
Prospectus. There are options outstanding to purchase up to 2,398,036 Common

    Unless stated otherwise in the applicable Prospectus Supplement, no holder
will have the right to require the Company to repurchase the Debt Securities and
there will be no increase in the interest rate if the Company becomes involved
in a highly leveraged transaction or if there is a change of control of the
Company.

    The Company may issue Debt Securities bearing no interest or interest at a
rate below the prevailing market rate at the time of issuance, and offer and
sell these Debt Securities at a discount below their stated principal amount.
The Company may also sell any of the Debt Securities for a currency or currency
unit other than United States dollars, and payments on the Debt Securities may
be payable in a currency or currency unit other than United States dollars. In
any of these cases, the Company will describe any Canadian and United States
federal income tax consequences and other special considerations in the
applicable Prospectus Supplement.

    The Company may issue Debt Securities with terms different from those of
Debt Securities previously issued and, without the consent of the holders
thereof, the Company may reopen a previous issue of a series of Debt Securities
and issue additional Debt Securities of such series (unless the reopening was
restricted when such series was created).

FORM, DENOMINATIONS AND EXCHANGE

    Debt Securities of a series may be issuable solely as registered securities,
solely as bearer securities or as both registered securities and bearer
securities. The Trust Indenture may also provide that Debt Securities of a
series will be issuable in global form. Unless otherwise indicated in the
Prospectus Supplement, bearer securities will have interest coupons attached.

    Registered Debt Securities of any series will be exchangeable for other
registered Debt Securities of the same series and of a like aggregate principal
amount and tenor in different authorized denominations. If (but only if)
provided in the Prospectus Supplement and Trust Indenture, bearer Debt
Securities (with all unmatured coupons, except as provided below, and all
matured coupons in default) of any series may be exchanged for registered Debt
Securities of the same series in any authorized denominations and of a like
aggregate principal amount and tenor. In such event, bearer Debt Securities
surrendered in a permitted exchange for registered Debt Securities between a
regular record date or a special record date and the relevant date for payment
of interest shall be surrendered without the coupon relating to such date for
payment of interest, and interest will not be payable on such date for payment
of interest in respect of the registered security issued in exchange for such
bearer security, but will be payable only to the holder of such coupon when due
in accordance with the terms of the Trust Indenture.

                                       13

    The applicable Prospectus Supplement may indicate the place or places to
register a transfer of Debt Securities. Except for certain restrictions set
forth in the Trust Indenture, no service charge will be made for any
registration of transfer or exchange of the Debt Securities, but the Company
may, in certain instances, require a sum sufficient to cover any tax or other
governmental charges payable in connection with these transactions.

    The Company shall not be required to: (i) issue, register the transfer of or
exchange Debt Securities of any series during a period beginning at the opening
of business 15 days before any selection of Debt Securities of that series is to
be redeemed and ending at the close of business on: (A) if Debt Securities of
the series are issuable only as registered securities, the day of mailing of the
relevant notice of redemption; or (B) if Debt Securities of the series are
issuable as bearer securities, the day of the first publication of the relevant
notice of redemption or, if Debt Securities of the series are also issuable as
registered securities and there is no publication, the mailing of the relevant
notice of redemption; (ii) register the transfer of or exchange any registered
Debt Security, or a portion thereof, called for redemption, except the
unredeemed portion of any registered security being redeemed in part;
(iii) exchange any bearer Debt Security selected for redemption, except that, to
the extent provided with respect to such bearer security, such bearer security
may be exchanged for a registered Debt Security of that series and like tenor,
provided that such registered security shall be immediately surrendered for
redemption with written instruction for payment consistent with the provisions
of the Trust Indenture; or (iv) issue, register the transfer of or exchange any
Debt Securities which have been surrendered for repayment at the option of the
holder, except the portion, if any, thereof not to be so repaid.

PAYMENT

    Unless stated otherwise in the Prospectus Supplement and the Trust
Indenture, the Company will make payments on the Debt Securities at the relevant
office or agency of the Debt Securities Trustee or the Company can make payments
by: (i) cheque mailed or delivered to the person entitled at the address
appearing in the security register of the Debt Securities Trustee; or (ii) wire
transfer to an account in the United States or Canada of the person entitled to
receive payments. Unless stated otherwise in the applicable Prospectus
Supplement, the Company will make payment to the persons in whose names the Debt
Securities are registered on the close of business on the day or days specified
in the Trust Indenture. The Company will make Debt Securities payments in other
forms at a place designated by the Company and specified in the applicable
Prospectus Supplement and Trust Indenture.

GLOBAL SECURITIES

    The registered Debt Securities of a series may be issued in whole or in part
in global form (a "Global Security") and will be registered in the name of and
be deposited with a depositary (the "Depositary"), or its nominee, each of which
will be identified in the Prospectus Supplement. Unless and until exchanged, in
whole or in part, for Debt Securities in definitive registered form, a Global
Security may not be transferred except as a whole by the Depositary for such
Global Security to a nominee of the Depositary, by a nominee of the Depositary
to the Depositary or another nominee of the Depositary or by the Depositary or
any such nominee to a successor of the Depositary or a nominee of the 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 Global Security
will be described in the Prospectus Supplement relating to such series and the
Trust Indenture. The Company anticipates that the following provisions will
apply to all depositary arrangements.

    Upon the issuance of a 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

                                       14

by the Global Security to the accounts of such persons having accounts with such
Depositary or its nominee ("Participants"). Such accounts shall be designated by
the underwriters, dealers or agents participating in the distribution of the
Debt Securities or by the Company if such Debt Securities are offered and sold
directly by the Company. Ownership of beneficial interests in a Global Security
will be limited to participants or persons that may hold beneficial interests
through participants. Ownership of beneficial interests in a Global Security
will be shown on, and the transfer of that ownership will be effected only
through, records maintained by the Depositary therefor or its nominee (with
respect to interest of Participants) or by Participants or persons that hold
through Participants (with respect to interests of persons other than
Participants). The laws of some states in the United States may require that
certain purchasers of securities take physical delivery of such securities in
definitive form.

    So long as the Depositary for a Global Security or its nominee is the
registered owner of the Global Security, such Depositary or such nominee, as the
case may be, will be considered the sole owner or holder of the Debt Securities
represented by the Global Security for all purposes under the Trust Indenture.
Except as provided below, owners of beneficial interests in a Global Security
will not be entitled to have Debt Securities of the series represented by the
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 Trust
Indenture.

    Any payments of principal of, premium, if any, and interest on Global
Securities registered in the name of a Depositary or its nominee will be made to
the Depositary or its nominee, as the case may be, as the registered owner of
the Global Security representing such Debt Securities. None of the Company, the
Debt Securities Trustee or any paying agent for Debt Securities represented by
the Global Securities will have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership
interests of the Global Security or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.

    The Company expects that the Depositary for a 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 the Global
Security as shown on the records of such Depositary or its nominee. The Company
also expects that payments by Participants to owners of beneficial interests in
a Global Security held through such Participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers registered in "street name", and will be the
responsibility of such Participants.

    If a Depositary for a Global Security representing a particular series of
Debt Securities is at any time unwilling or unable or no longer qualified to
continue as depositary and a successor depositary is not appointed by the
Company within 90 days, the Company will issue Debt Securities of such series in
definitive form in exchange for a Global Security representing such series of
Debt Securities. In addition, the Company may at any time and in its sole
discretion determine not to have Debt Securities of a series represented by a
Global Security and, in such event, will issue Debt Securities of a series in
definitive form in exchange for all of the Global Securities representing the
series of Debt Securities.

MERGER, AMALGAMATION OR CONSOLIDATION

    The Trust Indenture will provide that the Company may not consolidate with
or amalgamate or merge with or into any other person or convey, transfer or
lease its properties and assets substantially as an entirety to another person,
unless among other items:

    - the Company is the surviving person, or the resulting, surviving or
      transferee person, if other than the Company, is organized and existing
      under the laws of Canada, any province or territory thereof, the
      United States, any state thereof or the District of Columbia, or, if the

                                       15

      amalgamation, merger, consolidation or other transaction would not impair
      the rights of holders, any other country;

    - the successor person assumes all obligations of the Company under the Debt
      Securities and the Trust Indenture; and

    - the Company or such successor person will not be in default under the
      Trust Indenture immediately after the transaction.

    When such a person assumes the Company's obligations in such circumstances,
subject to certain exceptions, the Company shall be discharged from all
obligations under the Debt Securities and the Trust Indenture.

TAX REDEMPTION

    If and to the extent specified in an applicable Prospectus Supplement and
Trust Indenture, the Debt Securities of a series 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
(i) the Company determines that (A) 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 application or
interpretation of such laws, regulations or rulings (including a holding by a
court of competent jurisdiction), which change or amendment is announced or
becomes effective on or after a date specified in the applicable Prospectus
Supplement and Trust Indenture if any date is so specified, the Company has or
will become obligated to pay, on the next succeeding date on which interest is
due, Additional Amounts with respect to any Debt Security of such series as
described below under "Canadian Withholding Taxes"; or (B) on or after a date
specified in the applicable Prospectus Supplement, 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 province or territory thereof,
including any of those actions specified in (A) above, whether or not such
action was taken or decision was rendered with respect to the Company, or any
change, amendment, application or interpretation shall be officially proposed,
which, in any such case, in the written opinion to the Company of legal counsel
of recognized standing, will result in the Company becoming obligated to pay, on
the next succeeding date on which interest is due, Additional Amounts with
respect to any Debt Securities of such series; and (ii) in any such case, the
Company in its business judgment determines that such obligation cannot be
avoided by the use of reasonable measures available to the Company; provided
however, that (a) no such notice of redemption may be given earlier than
90 days prior to the earliest date on which the Company would be obligated to
pay such Additional Amounts were a payment in respect of the Debt Securities
then due, and (b) at the time such notice of redemption is given, such
obligation to pay such Additional Amounts remains in effect.

    In the event that the Company elects to redeem the Debt Securities of such
series pursuant to the provisions set forth in the preceding paragraph, the
Company shall deliver to the Debt Securities Trustee a certificate, signed by an
authorized officer, stating that the Company is entitled to redeem the Debt
Securities of such series pursuant to their terms.

CANADIAN WITHHOLDING TAXES

    If and to the extent specified in an applicable Prospectus Supplement and
Trust Indenture, all payments made by or on behalf of the Company under or with
respect to the Debt Securities 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 government charge (including penalties,
interest and other liabilities related thereto) imposed or levied by or on
behalf of the Government of Canada or of

                                       16

any province or territory thereof or by any authority or agency therein or
thereof having power to tax ("Canadian Taxes") unless the Company is required to
withhold or deduct Canadian Taxes by law or by the interpretation or
administration thereof by the relevant government authority or agency.

    If the Company is 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, the Company will pay as additional interest such additional
amounts ("Additional Amounts") as may be necessary so that the net amount
received by each holder of Debt Securities after such withholding or deduction
(including with respect to Additional Amounts) will not be less than the amount
the holder of Debt Securities would have received if such Canadian Taxes had not
been withheld or deducted (a similar payment will also be made to holders of
Debt Securities (other than Excluded Holders as defined herein) that are exempt
from withholding but required to pay tax under Part XIII of the INCOME TAX ACT
(Canada) (the "Tax Act") directly on amounts otherwise subject to withholding);
provided, however, that no Additional Amounts will be payable with respect to a
payment made to a holder of Debt Securities (an "Excluded Holder") in respect of
the beneficial owner thereof:

        (1) with which the Company does not deal at arm's length (for purposes
    of the Tax Act) at the time of the making of such payment;

        (2) which is subject to such Canadian Taxes by reason of its failure to
    comply with any certification, identification, information, documentation or
    other reporting requirement 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

        (3) which is subject to such Canadian Taxes by reason of its carrying on
    business in or being connected with Canada or any province or territory
    thereof otherwise than by the mere holding of Debt Securities or the receipt
    of payment thereunder.

    The Company will make such withholding or deduction and remit the full
amount deducted or withheld to the relevant authority as and when required in
accordance with applicable law. The Company will pay all taxes, interest and
other liabilities which arise by virtue of any failure of the Company to
withhold, deduct and remit to the relevant authority on a timely basis the full
amounts required in accordance with applicable law. The Company will furnish to
the holder of the Debt Securities, within 30 days after the date the payment of
any Canadian Taxes is due pursuant to applicable law, certified copies of tax
receipts evidencing such payment by the Company.

    The foregoing obligations shall survive any termination, defeasance or
discharge of the Trust Indenture.

PROVISION OF FINANCIAL INFORMATION

    Unless stated otherwise in an applicable Prospectus Supplement and Trust
Indenture, the Company will file with the Debt Securities Trustee and mail to
all holders of Debt Securities, as their names and addresses appear in the
security register, copies of its annual report or the information, documents and
other reports that the Company is required to provide to its shareholders
pursuant to the applicable Canadian securities legislation and the COMPANY ACT
(British Columbia) and information filed by the Company with the SEC. The
Company will agree to continue to provide the Debt Securities Trustee and
holders (a) within 140 days after the end of each financial year, an annual
report; and (b) within 60 days after the end of each of the first three
financial quarters of each financial year, quarterly reports, even if the
Company is no longer required to do so under the Canadian securities legislation
or the COMPANY ACT (British Columbia) and information filed by the Company with
the SEC. The information contained in these reports will be, at a minimum, the
information required to be provided

                                       17

in annual and quarterly reports by law in Canada to security holders of a
corporation with securities listed on the TSX whether or not the Company has any
of its securities listed on such stock exchange.

EVENTS OF DEFAULT

    When the Company uses the term "event of default" in this Prospectus, the
Company means:

    - the Company fails to pay principal of, or any premium on, any Debt
      Securities of that series when it is due;

    - the Company fails to pay interest or any additional amounts on any Debt
      Securities of that series for 30 days from the date such amounts are due;

    - the Company fails to comply with any of its other agreements in the Trust
      Indenture that affect or are applicable to the Debt Securities for
      60 days after the Company receives written notice from the Debt Securities
      Trustee or after the Company and the Debt Securities Trustee receive
      written notice from the holders of at least 25% in aggregate principal
      amount of the outstanding Debt Securities;

    - certain events involving its bankruptcy, insolvency or
      reorganization; and

    - any other event of default provided for that series of Debt Securities in
      the Trust Indenture.

    An event of default under one series of Debt Securities will not necessarily
be an event of default under another series. The Debt Securities Trustee may
withhold notice to the holders of Debt Securities of any event of default
(except in the payment of principal or interest) if in good faith it considers
it in the interests of the holders to do so.

    If an event of default for any series of Debt Securities occurs and
continues, the Debt Securities Trustee or the holders of at least 25% in
aggregate principal amount of the Debt Securities of that series, subject to any
subordination provisions, may require the Company to repay immediately:

    - the entire principal of the Debt Securities of the series; or

    - if the Debt Securities are discounted securities, that portion of the
      principal as is described in the applicable Prospectus Supplement and
      Trust Indenture.

    If an event of default relates to events involving the Company's bankruptcy,
insolvency or reorganization, the principal of all Debt Securities will become
immediately due and payable without any action by the Debt Securities Trustee or
any holder. Subject to certain conditions, the holders of a majority of the
aggregate principal amount of the Debt Securities of the affected series can
rescind this accelerated payment requirement.

    If Debt Securities are discounted securities, the applicable Prospectus
Supplement will contain provisions relating to the acceleration of maturity of a
portion of the principal amount of the discounted securities upon the occurrence
or continuance of an event of default.

    Other than its duties in case of an event of default, the Debt Securities
Trustee is not obligated to exercise any of its rights or powers under the Trust
Indenture at the request, order or direction of any holders, unless the holders
offer the Debt Securities Trustee reasonable indemnity. If they provide this
reasonable indemnity, the holders of a majority in principal amount of any
series of Debt Securities may, subject to certain limitations, direct the time,
method and place of conducting any proceeding or any remedy available to the
Debt Securities Trustee, or exercising any power conferred upon the Debt
Securities Trustee, for any series of Debt Securities.

    The Company will be required to furnish to the Debt Securities Trustee a
statement annually as to its compliance with all conditions and covenants under
the Trust Indenture and, if the Company is not in compliance, the Company must
specify any events of default.

                                       18

    No holder of Debt Securities of any series will have any right to institute
any proceeding with respect to the Trust Indenture, or for the appointment of a
receiver or a trustee, or for any other remedy, unless:

        (1) the holder has previously given to the Debt Securities Trustee
    written notice of a continuing event of default with respect to the Debt
    Securities of the affected series;

        (2) the holders of at least 25% in principal amount of the outstanding
    Debt Securities of the series affected by an event of default have made a
    written request, and the holders have offered reasonable indemnity, to the
    Debt Securities Trustee to institute a proceeding as trustee; and

        (3) the Debt Securities Trustee has failed to institute a proceeding,
    and has not received from the holders of a majority in aggregate principal
    amount of the outstanding Debt Securities of the series affected by an event
    of default a direction inconsistent with the request, within 60 days after
    their notice, request and offer.

    However, the above limitations do not apply to a suit instituted by a holder
of Debt Securities for the enforcement of payment of principal of, or any
premium or interest on, the Debt Securities on or after the applicable due date
specified in the Debt Securities.

DEFEASANCE

    When the Company uses the term "defeasance" in this Prospectus, the Company
means discharge from some or all of its obligations under a Trust Indenture. If
the Company deposits with the Debt Securities Trustee sufficient cash or
government securities to pay the principal, interest, any premium and any other
sums due to the stated maturity date or a redemption date of the Debt Securities
of a series, then at its option:

    - the Company will be discharged from its obligations with respect to the
      Debt Securities of that series; or

    - the Company will no longer be under any obligation to comply with certain
      restrictive covenants under the Trust Indenture, and certain events of
      default will no longer apply to the Company.

    If this happens, the holders of the Debt Securities of the affected series
will not be entitled to the benefits of the Trust Indenture except for
registration of transfer and exchange of Debt Securities and the replacement of
lost, stolen or mutilated Debt Securities. These holders may look only to the
deposited fund for payment on their Debt Securities.

    To exercise its defeasance option, the Company must deliver to the Debt
Securities Trustee:

        (1) an opinion of counsel in Canada or a ruling from the Canada Customs
    and Revenue Agency to the effect that the holders of the outstanding Debt
    Securities of the affected series will not recognize income, gain or loss
    for Canadian federal, provincial or territorial income or other tax purposes
    as a result of a defeasance and will be subject to Canadian federal or
    provincial income tax and other tax on the same amounts, in the same manner
    and at the same times as would have been the case had the defeasance not
    occurred;

        (2) an opinion of counsel in the United States to the effect that the
    holders of the outstanding Debt Securities of the affected series will not
    recognize gain or loss for United States federal income tax purposes as a
    result of a defeasance and will be subject to United States federal income
    tax on the same amounts, in the same manner and at the same times as would
    have been the case if the defeasance had not occurred; and

        (3) a certificate of an officer of the Company and an opinion of
    counsel, each stating that all conditions precedent provided for relating to
    defeasance have been satisfied.

                                       19

    If the Company will be discharged from its obligations with respect to the
Debt Securities, and not just from its covenants, the U.S. opinion must be based
upon a ruling from or published by the United States Internal Revenue Service or
a change in law to that effect.

    In addition to the delivery of the opinions described above, the following
conditions must be met before the Company may exercise its defeasance option:

    - no event of default or event that, with the passing of time or the giving
      of notice, or both, shall constitute an event of default shall have
      occurred and be continuing for the Debt Securities of the affected series;

    - the Company is not an "insolvent person" within the meaning of applicable
      bankruptcy and insolvency legislation; and

    - other customary conditions precedent are satisfied.

MODIFICATION AND WAIVER

    The Company may modify a Trust Indenture with the consent of the holders of
a majority in aggregate principal amount of the outstanding Debt Securities of
each series affected by the modification. However, without the consent of each
holder affected, no modification may:

    - change the stated maturity of the principal of (or premium, if any), or
      any installment of interest, if any, on any Debt Securities;

    - reduce the principal, premium, if any, or interest rate or any obligation
      to pay any additional amounts;

    - reduce the amount of principal of a Debt Security payable upon
      acceleration of its maturity;

    - change the place or currency of any payment;

    - affect the holder's right, if any, to require the Company to repurchase
      the Debt Securities at the holder's option;

    - impair the right of the holders to institute a suit to enforce their
      rights to payment;

    - adversely affect any conversion or exchange right related to a series of
      Debt Securities;

    - change the percentage of Debt Securities required to modify the Trust
      Indenture or to waive compliance with certain provisions of the Trust
      Indenture; or

    - reduce the percentage in principal amount of outstanding Debt Securities
      necessary to take certain actions.

    The holders of a majority in principal amount of outstanding Debt Securities
of any series may on behalf of the holders of all Debt Securities of that series
waive, in so far as only that series is concerned, past defaults under the Trust
Indenture and the Company's compliance with certain restrictive provisions of
the Trust Indenture. However, these holders may not waive a default in any
payment on any Debt Securities or compliance with a provision that cannot be
modified without the consent of each holder affected.

    The Company may modify the Trust Indenture without the consent of the
holders to:

    - evidence its successor under the Trust Indenture;

    - add to covenants or surrender any right or power for the benefit of
      holders;

    - add events of default;

                                       20

    - provide for bearer securities to become registered securities under the
      Trust Indenture and make other such changes to bearer securities that in
      each case do not materially and adversely affect the interests of holders
      of outstanding Debt Securities;

    - establish the forms of the Debt Securities;

    - appoint a successor trustee under the Trust Indenture;

    - add provisions to permit or facilitate the defeasance or discharge of the
      Debt Securities as long as there is no adverse affect on the holders;

    - cure any ambiguity, correct or supplement any defective or inconsistent
      provision, make any other provisions in each case that would not
      materially and adversely affect the interests of holders of outstanding
      securities and related coupons, if any; or

    - to change or eliminate any provisions where such change takes effect when
      there are no securities outstanding under the Trust Indenture.

GOVERNING LAW

    The Trust Indenture and the Debt Securities will be governed by and
construed in accordance with the laws of the Province of British Columbia and
the federal laws of Canada applicable in British Columbia.

THE TRUSTEE

    The Debt Securities Trustee under the Trust Indenture or its affiliates may
provide banking, registrar and transfer agency and other services to the Company
in the ordinary course of their business.

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

                              PLAN OF DISTRIBUTION

GENERAL

    The Company may offer and sell the Securities, separately or together:
(i) to one or more underwriters or dealers; (ii) through one or more agents; or
(iii) directly to one or more other purchasers. The Securities offered pursuant
to any Prospectus Supplement may be sold from time to time in one or more
transactions at: (i) a fixed price or prices, which may be changed from time to
time; (ii) market prices prevailing at the time of sale; (iii) prices related to
such prevailing market prices; or (iv) other negotiated prices. The Company may
only offer and sell the Securities pursuant to a Prospectus Supplement during
the 25-month period that this Prospectus, including any amendments hereto,
remains valid. The Prospectus Supplement for any of the Securities being offered
thereby will set forth the terms of the offering of such Securities, including
the type of Security being offered, the name or names of any underwriters,
dealers or agents, the purchase price of such Securities, the proceeds to the
Company from such sale, any underwriting commissions or discounts and other
items constituting underwriters' compensation and any discounts or concessions

Prospectus Supplement are deemed to be underwriters in connection with the
Securities offered thereby.

                                       21

BY UNDERWRITERS OR DEALERS

    If underwriters are used in the sale, the Securities will be acquired by the
underwriters for their own account and may be resold from time to time in one or
more transactions, including negotiated transactions, at a fixed public offering
price or at varying prices determined at the time of sale. Unless otherwise set
forth in the Prospectus Supplement relating thereto, the obligations of
underwriters to purchase the Securities will be subject to certain conditions,
but the underwriters will be obligated to purchase all of the Securities offered
by the Prospectus Supplement if any of such Securities are purchased. The
Company may agree to pay the underwriters a fee or commission for various
services relating to the offering of any Securities. Any such fee or commission
will be paid out of the general corporate funds of the Company.

    If dealers are used, and if so specified in the applicable Prospectus
Supplement, the Company will sell such Securities to the dealers as principals.
The dealers may then resell such Securities to the public at varying prices to
be determined by such dealers at the time of resale. Any public offering price
and any discounts or concessions allowed or re-allowed or paid to dealers may be
changed from time to time.

BY AGENTS

    The Securities may also be sold through agents designated by the Company.
Any agent involved will be named, and any fees or commissions payable by the
Company to such agent will be set forth, in the applicable Prospectus
Supplement. Any such fees or commissions will be paid out of the general
corporate funds of the Company. Unless otherwise indicated in the Prospectus
Supplement, any agent will be acting on a best efforts basis for the period of
its appointment.

DIRECT SALES

    Securities may also be sold directly by the Company at such prices and upon
such terms as agreed to by the Company and the purchaser. In this case, no
underwriters, dealers or agents would be involved in the offering.

GENERAL INFORMATION

    Underwriters, dealers or agents who participate in the distribution of
Securities may be entitled under agreements to be entered into with the Company
to indemnification by the Company against certain liabilities, including
liabilities under Canadian provincial and United States 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 or
agents may be customers of, engage in transactions with, or perform services
for, the Company in the ordinary course of business.

    In connection with any offering of Securities, underwriters may over-allot
or effect transactions which stabilize or maintain the market price of the

open market. Such transactions may be commenced, interrupted or discontinued at
any time.

    In accordance with the rules of the National Association of Securities
Dealers, Inc., the Company will not pay a commission to a broker-dealer in
connection with any sale of Securities under this Prospectus that is in excess
of 6%.

                     CHANGES TO CONSOLIDATED CAPITALIZATION

    Since December 31, 2002, the following changes have occurred to the share
and loan capital of the Company, on a consolidated basis:

    - on February 20, 2003, the Company completed the acquisition of Corner Bay
      Silver Inc. by issuing 7,636,659 Common Shares and 3,818,329 warrants to
      purchase Common Shares (having an exercise price of Cdn$12.00 for a
      five-year period ending February 20, 2008). The Company also granted
      553,846 stock options to purchase Common Shares (having exercise prices of
      between Cdn$4.55 and Cdn$12.00 and having exercise periods of between one
      and five years from the date of grant) in consideration for the
      termination of 960,000 fully vested stock options held by employees and
      shareholders of Corner Bay;

    - the Company issued 507,171 Common Shares pursuant to the exercise of stock
      options;

    - the Company issued 100,000 Common Shares pursuant to the exercise of
      warrants;

    - the Company reduced its $5.15 million loan on the Huaron property from
      Banco de Credito del Peru by $812,000. The Huaron loan bears interest at
      six-month LIBOR plus 3% and is repayable at the rate of $135,417 per
      month;

    - Pan American drew down $8,000,000 of its $10,000,000 La Colorada project
      loan facility with International Finance Corporation ("IFC"). The IFC loan
      bears interest at six-month LIBOR plus 3.50% until certain technical and
      financial tests are achieved and six-month LIBOR plus 3.25% thereafter.
      The IFC loan is repayable in semi-annual instalments of $1,000,000
      commencing November 14, 2004. In addition to the interest payments on the
      outstanding balance of the IFC loan, Pan American will be required to make
      additional payments to IFC if the average price of silver for a year
      exceeded $4.75 per ounce. Such payment would be equal to 20% of the
      positive difference between the average price per ounce of silver for a
      year and $4.75 multiplied by the number of ounces of silver produced by
      the La Colorada mine divided by $10,000,000 and multiplied by the greater
      of the loan balance at the end of the year or the originally scheduled
      loan balance at the end of a year; and

    - Pan American has sold forward 11,400 tonnes of zinc. These sales were
      designated as a hedge and represent sales of 1,100 tonnes per month for
      each of the months of June 2003 through and including February 2004 at a
      price of $824 per tonne and sales of 500 tonnes per month for each of the
      months of March 2004 through and including May 2004 at a price of $817 per
      tonne. The difference between the average monthly London zinc cash
      settlement price and the forward sales price will be credited or charged
      to Pan American's revenue during the June 2003 through May 2004 period.

purchaser should refer to any applicable provisions of the Securities
legislation of the purchaser's province for the particulars of these rights or
consult with a legal adviser.

                                AUDITORS' REPORT

To the Directors of
Corner Bay Silver Inc.

    We have audited the consolidated balance sheets of Corner Bay Silver Inc. as
at June 30, 2002 and 2001 and the consolidated statements of operations and
deficit and cash flows for each of the years in the three-year period ended
June 30, 2002. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

    We conducted our audits in accordance with Canadian and United States
generally accepted auditing standards. Those standards require that we plan and
perform an audit to obtain reasonable assurance whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.

    In our opinion, these consolidated financial statements present fairly, in
all material respects, the financial position of the Company as at June 30, 2002
and 2001 and the results of its operations and its cash flows for each of the
years in the three-year period ended June 30, 2002 in accordance with Canadian
generally accepted accounting principles.

   COMMENTS BY AUDITORS FOR U.S. READERS ON CANADA-U.S. REPORTING DIFFERENCES

    In the United States, reporting standards for auditors require the addition
of an explanatory paragraph (following the opinion paragraph) when the financial
statements are affected by conditions and events that cast substantial doubt on
the Company's ability to continue as a going concern, such as those described in
note 1 to the consolidated financial statements. Our report to the shareholders
dated September 6, 2002 is expressed in accordance with Canadian reporting
standards, which do not permit a reference to such events and conditions in the
auditors' report when they are adequately disclosed in the financial statements.

    DECEMBER 31, 2002 AND 2001 (UNAUDITED) AND JUNE 30, 2002, 2001 AND 2000

                        (EXPRESSED IN CANADIAN DOLLARS)

1.  NATURE OF OPERATIONS AND GOING CONCERN

    The Company is in the process of exploring its mineral properties and is
establishing the amount of ore reserves that are economically recoverable from
the Mexico property. The recoverability of amounts shown for these properties
and related deferred exploration expenditures are dependent upon the discovery
of economically recoverable reserves, the preservation of the Company's interest
in the underlying mineral claims, the ability of the Company to obtain the
financing necessary to complete the development of the properties, and future
profitable production or, alternatively, upon the Company's ability to dispose
of its interest on an advantageous basis. Changes in future conditions could
require material writedowns of the carrying amounts of deferred exploration
expenditure.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    These consolidated financial statements have been prepared in accordance
with Canadian generally accepted accounting principles (GAAP). Significant
differences from United States accounting principles are disclosed in Note 15.

BASIS OF CONSOLIDATION

    These consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries, Corner Bay Resources Inc. and Pan MacKenzie
Resources Inc. (including its wholly owned subsidiary Minera Corner Bay S.A. de
C.V.).

DEFERRED EXPLORATION EXPENDITURE

    The deferred exploration expenditure is recorded at cost, net of incidental
revenues generated from the particular properties. These net costs are deferred
until the properties to which they relate are placed into production, sold or
abandoned.

    In March 2000, the Accounting Standards Board of the Canadian Institute of
Chartered Accountants (CICA) issued Accounting Guideline No. 11 entitled,
"Enterprises in the Development Stage" (AcG 11), and subsequently, on March 12,
2002, issued Emerging Issues Committee (EIC) 126 "Accounting by Mining
Enterprises for Exploration Costs." These guidelines address three distinct
issues: (i) capitalization of costs/expenditures (ii) impairment and
(iii) disclosure. Prior to their issuance, development state entities were
exempt from following certain aspects of Canadian generally accepted accounting
principles (GAAP). EIC 126 and AcG 11 require that all companies account for
transactions based on the underlying characteristics of the transactions rather
than the maturity of the enterprise. In addition, EIC 126 and AcG 11 require
specific disclosure of information by development stage companies. These
guidelines were effective for financial periods beginning on or after April 1,
2000, which affects the Company's financial years ended on or after
June 30, 2001.

    EIC 126 and AcG 11 affect mining companies with respect to the deferral of
exploration costs. The appropriate accounting guidance is contained in
Section 3061, "Property, Plant and Equipment" of the CICA Handbook which
permits, but does not require, exploration costs to be capitalized as part of a
mining property, if the Company considers that such costs have the
characteristics of property, plant and equipment. Under this view, deferred
exploration expenditure would not automatically be subject to regular assessment
of recoverability, unless conditions such as those discussed in EIC 126 and
AcG 11 exist.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

    DECEMBER 31, 2002 AND 2001 (UNAUDITED) AND JUNE 30, 2002, 2001 AND 2000

                        (EXPRESSED IN CANADIAN DOLLARS)

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    There would need to be an assessment of deferred exploration expenditure.
Assessment of the probability of recoverability of deferred exploration
expenditure from future operations will require the preparation of a projection
based on objective evidence of economic reserves such as a feasibility study.

    The status of the Company's operations is such that, like most mining
companies in the exploration stage, it would not be practical to obtain a
feasibility study or provide other information that could be used to support
capitalization of deferred exploration expenditure under the alternative view.

    EIC 126 and AcG 11 did not have a significant impact on the Company's
consolidated financial statements.

PROPERTY, PLANT AND EQUIPMENT

    Land and exploration equipment are recorded at cost. Exploration equipment
is amortized on a reducing balance basis at various rates from 14% to 33%.
Amortization relating to equipment used on the mineral properties is capitalized
as part of the deferred exploration expenditure balance.

ASSETS UNDER CONSTRUCTION

    Assets under construction consist of equipment to be commissioned at the
Mexico property site. The assets will be included as part of the equipment
balance once refurbished and transferred to the site. These assets are not being
amortized, as they are not currently ready for use.

FINANCIAL INSTRUMENTS

    The carrying amounts of cash, receivables, prepaid expenses and deposits,
accounts payable and accrued liabilities approximate the fair values of those
financial instruments due to the short-term maturities of such instruments.
Financial instruments that potentially subject the Company to concentrations of
credit risk consist primarily of cash. The Company places its cash with high
credit quality financial institutions.

INCOME TAXES

    The provision for future income taxes is based on the liability method.
Future income taxes arise from the recognition of the tax consequences of
temporary differences by applying statutory income tax rates applicable to
future years to differences between the financial statements' carrying amounts
and the income tax bases of certain assets and liabilities. The Company records
a valuation allowance against any portion of those future income tax assets that
it believes is not, more likely than not, to be realized.

STOCK-BASED COMPENSATION PLAN

    The Company has one stock option plan, which is described in note 5. No
compensation expense is recognized for this plan when stock or stock options are
issued to employees. Any consideration paid on exercise of stock options or
purchase of stock is credited to capital stock.

                                      F-8

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

    DECEMBER 31, 2002 AND 2001 (UNAUDITED) AND JUNE 30, 2002, 2001 AND 2000

                        (EXPRESSED IN CANADIAN DOLLARS)

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Effective July 1, 2002, the Company adopted the new recommendations of the
Canadian Institute of Chartered Accountants Handbook Section 3870, Stock-based
Compensation and Other Stock-based Payments. This section establishes standards
for the recognition, measurement and disclosure of stock-based compensation and
other stock-based payments in exchange for goods and services. The section
requires that all stock-based awards made to non-employees be measured and
recognized using a fair-value based method. The section encourages a fair-value
based method for all awards granted to directors, officers and employees, but
only requires the use of a fair value based method for direct awards of stock,
stock appreciation rights and awards that call for settlement in cash or other
assets.

    For stock options granted to directors, officers and employees, the Company
has adopted the intrinsic value method of accounting for stock-based
compensation. Under this method compensation expense is recognized for the
excess, if any, of the quoted market price of the Company's common shares over
the common share option exercise price on the day that options are granted.

LOSS PER SHARE

    Basic loss per share is computed by dividing the loss for the year by the
weighted average number of common shares outstanding during the year, including
contingently issuable shares that are included when the conditions necessary for
issuance have been met. Diluted earnings per share are calculated in a manner
similar to basic earnings per share, except the weighted average number of
shares outstanding are increased to include potential common shares from the
assumed exercise of options and warrants, if dilutive. The number of additional
shares included in the calculation is based on the treasury stock method for
options and warrants and on the as if converted method for convertible
securities.

    During the year ended June 30, 2001, the Company changed its method of
accounting for earnings per share to comply with the revised standard issued by
the CICA Handbook, Section 3500, "Earnings per share". There was no difference
between the loss per share calculated under the new standard and the amount that
would have been calculated using the previous standard.

USE OF ESTIMATES

    The preparation of financial statements in conformity with Canadian
generally accepted accounting principles (GAAP) requires management to make
estimates and assumptions that affect the reported amounts of assets,
liabilities, revenue and expenses during the reporting period. Actual results
could differ from these estimates.

TRANSLATION OF FOREIGN CURRENCIES

    As the Company considers all of its foreign operations to be fully
integrated, all items denominated in foreign currencies have been translated
using the temporal method. Under this method, monetary assets and liabilities
and non-monetary items carried at market values are translated at the year and
period end exchange rate. Other non-monetary items and revenue and expenses are
translated at approximate rates in effect at the dates of the transactions,
except depletion and amortization, which are translated at the same rates as the
related assets.

    The Alamo Dorado silver/gold property is located in the northwestern state
of Sonora, Mexico. Paved roads connect the state capital of Hermosillo to the
town of Alamos, which is 67 kilometers northwest of the Alamo Dorado Project.

    The 5,369 hectare property consists of the 504 hectare Alamo Ocho concession
held under option by the Company, and the 4,865 hectare Alamo Dorado concession,
which is owned 100% by the Company and surrounds the Alamo Ocho concession. The
Company can earn a 100% interest in Alamo Ocho by paying US$800,000 over six
years. Payments are made semi-annually, of which US$441,000 (unaudited) was paid
to December 31, 2002 (June 30, 2002, 2001 and 2000 were US$450,000, $325,000 and
$nil, respectively).

    During the year ended June 30, 2002, the Company incurred $131,147 (2001 and
2000 -- $nil) in rental payments, and is committed to annual rental payments of
$114,150. During the six-month periods ended December 31, 2002 and 2001, the
Company incurred $35,906 and $23,491 (unaudited), respectively, in rental
payments.

OPTIONS

    On December 15, 1995, the shareholders of the Company approved the amended
stock option plan (dated November 1, 1995) (the Plan) which provides for the
issuance of 1.0 million stock options under the terms of the Plan. On
December 20, 1999 and December 15, 2000, the shareholders approved an amendment
to provide for the further issuance of an additional 1.4 and 2.0 million common
share options, respectively, under the terms of the Plan.

    Under the Plan, the Company provides options to buy common shares of the
Company to directors, officers and service providers. The board of directors
grants such options for periods of up to ten years at prices not lower than the
market price at the date of granting.

    No compensation expense is recognized when stock options are issued to
employees and directors. All consideration paid by employees from the exercise
of stock options or purchase of stock is credited to capital stock.

    Compensation expense is recorded when stock options are issued to
non-employees and is recognized over the vesting period of the options.
Compensation expense is determined as the fair value of the options at the date
of grant using an option-pricing model. During the six months ended
December 31, 2002 and year ended June 30, 2002, no stock options were issued to
non-employees.

    On June 18, 2002, assets under construction were acquired for $3,442,500,
through issuance of common shares (note 4). The purchase price was based on the
value of the common shares.

12.  ACQUISITION OF COMPANY BY PAN AMERICAN SILVER CORP.

    On May 21, 2002, the Company and Pan American Silver Corp. (Pan American)
announced a proposed plan of arrangement whereby Pan American would acquire all
of the issued and outstanding shares of the Company. On June 28, 2002, both
companies announced amended terms to the proposed plan of arrangement. The
amended proposal for a plan of arrangement is subject to approval of the
shareholders of the Company and Pan American and approval by the Ontario
Superior Court of Justice and various regulatory authorities. The shareholders
of the Company and Pan American approved the plan of arrangement on September 4
and 5, 2002, respectively. If remaining approvals are obtained and all material
covenants are satisfied in a timely fashion, the plan of arrangement would
become effective in September 2002.

    Under the terms of the amended plan of arrangement, each Corner Bay
Silver Inc. common share would be exchanged for 0.3846 of a Pan American common
share and 0.1923 of a Pan American common share purchase warrant. Each whole Pan
American common share purchase warrant (the Pan American Warrant) provides the
holder with the rights to purchase a Pan American common share at CAN$12 for a
five-year period after the effective date of the plan of arrangement ("Plan of
Arrangement"). The Pan American Warrants will trade on the Toronto Stock
Exchange.

13.  SUBSEQUENT EVENT

    In July 2002, the principal mineral concession, which hosts the Alamo Dorado
concession, was purchased outright from the concession owners by paying the
remaining option payments in a final lump sum payment of US$345,000 (US$300,000
plus Impuesto Al Valor Agregado (IVA) taxes).

SUBSEQUENT EVENT (UNAUDITED)

    The Company received regulatory approval on the plan on arrangement and on
February 20, 2003 the Company and Pan American Silver Corp. completed the Plan
of Arrangement.

------------------------

(a) In accordance with U.S. GAAP, the Company would be required to charge all
    costs of deferred exploration expenditures to earnings as operating expenses
    as incurred until proven economic reserves are established. As a result of
    accounting for these expenditures in this manner, the unaudited loss for the
    six months ended December 31, 2002 and 2001 would be increased by $537,714
    and $1,415,279, respectively, and loss for the years ended June 30, 2002,
    2001 and 2000 would be increased by $3,154,793, $1,039,657 and $993,487,
    respectively.

(b) The Company accounts for its share options using the intrinsic value method,
    which in the Company's circumstances amounts does not result in different
    from the amounts that would be determined under the provisions of the
    Accounting Principles Board (APB) Opinion No. 25, "Accounting for Stock
    Issued to Employees," (APB 25) and related interpretations. Accordingly, no
    compensation expense for its share option plan has been recognized or
    recorded in the consolidated statement of operations and deficit for any of
    the years presented. A company that does not adopt the fair value method
    must disclose the cost of the stock compensation awards at their fair value
    at the date the award is granted. The unaudited value of the Company's
    options that were granted during six months ended December 31, 2002 was $nil
    (2001 -- $17,846) (three years ended June 30, 2002 were $447,952, $37,605
    and $878,747, respectively). The fair value for 2002 was estimated using the
    Black-Scholes model with assumptions of a three-year expected term
    volatility ranging from 50% to 56% and interest rates from 3.75% to 4.04%.

15.  DIFFERENCE BETWEEN CANADIAN AND UNITED STATES GENERALLY ACCEPTED ACCOUNTING
PRINCIPLES (GAAP) (CONTINUED)
NEW STANDARDS FOR U.S. GAAP

    In June 2001, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standard (SFAS) No. 142, "Goodwill and Other
Intangible Assets". This new standard features new accounting rules for goodwill
and intangible assets. The Company does not foresee any impact on a cumulative
effect of an accounting change or on the carrying value of assets and
liabilities recorded in the consolidated balance sheets upon adoption.
SFAS No. 142 will be adopted on July 1, 2002.

    Also issued in June 2001 was SFAS No. 143, "Accounting for Asset Retirement
Obligations." This statement addresses financial accounting and reporting for
obligations associated with the retirement of tangible long-lived assets and the
associated asset retirement costs. It requires that the fair value of a
liability for an asset retirement obligation be recognized in the period in
which it is incurred if a reasonable estimate of a fair value can be made. The
associated asset retirement costs are capitalized as part of the carrying amount
of the long-lived asset. The Company is analyzing the impact of SFAS No. 143
and will adopt this standard on July 1, 2002.

    In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment
or Disposal of Long-lived Assets." This statement supersedes SFAS No. 121
and the accounting and reporting provisions of APB 30, and also amends ARB 51.
This statement will require one accounting model be used for long-lived assets
to be disposed of by sale, whether previously held and used or newly acquired,
and will broaden the presentation of discontinued operations to include more
disposal transactions. The Company is analyzing the impact of SFAS No. 144
and will adopt this standard on July 1, 2002.

    Effective July 1, 2002, the Company will adopt, for United States reporting
purposes, SFAS No. 145, "Rescission of FASB Statements No. 4, 44 and 64,
Amendments of SFAS No. 13, and Technical Corrections as of April 2002." This
statement rescinds SFAS No. 4, "Reporting Gains and Losses from Extinguishment
of Debt," and an amendment of that statement, SFAS No. 64, "Extinguishment of
Debt Made to Satisfy Sinking-Fund Requirements".

    This statement also rescinds SFAS No. 44, "Accounting for Intangible Assets
of Motor Carriers." This statement amends SFAS No. 13, "Accounting for Leases",
to eliminate an inconsistency between the required accounting for sale-leaseback
transactions and the required accounting for certain lease modifications that
have economic effects that are similar to sale-leaseback transactions. This
statement also amends other existing authoritative pronouncements to make
various technical corrections, clarify meanings or describe their applicability
under changed conditions. The adoption of the new standard is not currently
expected to have a significant impact on the Company's results of operations or
financial position.

15.  DIFFERENCE BETWEEN CANADIAN AND UNITED STATES GENERALLY ACCEPTED ACCOUNTING
PRINCIPLES (GAAP) (CONTINUED)
NEW STANDARDS FOR U.S. GAAP, UNAUDITED TO DECEMBER 31, 2002

    The Company adopted the following standards on July 1, 2002:

    (i) the adoption of SFAS No. 142, Goodwill and Other Intangible Assets, did
not have a material affect on the Company's consolidated financial position or
results of operations.

    (ii) the adoption of SFAS No. 143, Accounting for Asset Retirement
Obligations, did not have a material impact on the Company's results of
operations or shareholders' equity.

    (iii) the adoption of SFAS No. 144, Accounting for the Impairment or
Disposal of Long-lived Assets, did not have a material affect on the Company's
consolidated financial position or results of operations.

    (iv) the adoption of SFAS No. 145, Rescission of FASB Statements No. 4, 44
and 64, Amendments of SFAS No. 13, and Technical Corrections as of April 2002,
did not have a material affect on the Company's results of operations or its
financial position.

FINANCIAL ACCOUNTING STANDARDS BOARD (FASB)

    On July 30, 2002, the FASB issued SFAS No. 146, "Accounting for Costs
Associated with Exit or Disposal Activities." The standard requires companies to
recognize costs associated with exit or disposal activities when they are
incurred rather than at the date of a commitment to an exit or disposal plan.
Examples of costs covered by the standard include lease termination costs and
certain employee severance costs that are associated with a restructuring,
discontinued operation, plant closing or other exit or disposal activity.
SFAS No. 146 is to be applied retroactively to exit or disposal activities
initiated after December 31, 2002. The adoption of the new standard is not
currently expected to have a significant impact on the Company's result of
operations or financial position.

NEW STANDARD FOR CANADIAN GAAP

    The CICA approved a new Handbook Section 3062, "Goodwill and Other
Intangible Assets," which require intangible assets with an indefinite life and
goodwill to be tested for impairment on annual basis. Goodwill and indefinite
life intangible assets will no longer be amortized. Intangible assets with
definite lives will continue to be amortized over their useful lives. The new
section is consistent with those recently approved by the FASB (SFAS No. 142).
The adoption of this new standard is not expected to have any material effect on
the Company's financial position, results of operations or cash flows.
Section 3026 was adopted on July 1, 2002 and the Company does not expect this
adoption to have a significant impact on the Company's results of operations or
financial position.

Silver Corp. ("Pan American") as at December 31, 2002 and for the three months
ended March 31, 2003 and the year ended December 31, 2002 have been prepared by

    (a) A pro forma balance sheet combining the audited balance sheet of Pan
American as at December 31, 2002 with the unaudited balance sheet of Corner Bay
as at December 31, 2002; and

    (b) A pro forma statement of operations combining the audited statement of
operations of Pan American for the year ended December 31, 2002 with the

ended December 31, 2002.

    (c) A pro forma statement of operations combining the unaudited statement of
operations of Pan American for the three months ended March 31, 2003 with the
unaudited statement of operations of Corner Bay for the three month period ended
March 31, 2003.

    The pro forma balance sheet at December 31, 2002 has been prepared as if the
transactions described in Note 3 had occurred on December 31, 2002. The

statements include all adjustments necessary for the fair presentation of the

accounting principles applied on a basis consistent with Pan American's
accounting policies. The pro forma consolidated financial statements are not
intended to reflect the results of operations or the financial position of Pan

effected on the dates indicated. Further, the pro forma financial information is
not necessarily indicative of the results of operations that may be obtained in
the future.

    The unaudited pro forma financial statements should be read in conjunction
with the historical financial statements and notes thereto of Pan American and
Corner Bay described above.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The unaudited pro forma financial statements have been compiled using the
significant accounting policies as set out in the audited financial statements
of Pan American for the year ended December 31, 2002. The significant accounting
policies of Corner Bay conform in all material respects to those of Pan
American, except as described in and adjusted for in Note 4 (d).

3.  BUSINESS COMBINATION

    ACQUISITION OF CORNER BAY

    On February 20, 2003, Pan American completed its proposed merger with Corner
Bay. Under the terms of the acquisition common shares of Corner Bay were,
directly or indirectly, exchanged for common shares of Pan American and warrants
to purchase Pan American common shares, on the basis of one Pan American common
share for every 2.60 Corner Bay shares and one Pan American warrant for every
5.20 Corner Bay common shares. Pan American also agreed to issue 553,846 stock
options to replace 960,000 fully vested stock options currently held by Corner
Bay employees and directors.

    Each whole Pan American warrant will allow the holder to purchase a Pan
American common share for a price of Cdn.$12.00 for a five-year period ended
February 20, 2008.

    As a result, Pan American issued 7,636,659 common shares to the shareholders
of Corner Bay, and 3,818,329 warrants to purchase common shares. The common
shares issued were valued at $54,203,000 which was derived from an issue price
of $11.30 translated at $0.6595 for each U.S. dollar, less a deemed 5% issue
cost of $2,707,000. The share purchase warrants were valued at $8,889,000, which
was derived from a warrant valued at $2.328 per warrant. The warrants were
valued using an option pricing model assuming a weighted average volatility of
the Company's share price of 35% and a weighted average annual risk free rate of
4.16%. The value of the stock options granted was determined to be $1,136,000.

                                                              ============


    The purchase consideration of $64,748,000 for 100% of Corner Bay exceeds the
carrying value of the net assets at December 31, 2002 by $53,880,000 which has
been applied to increase the carrying value of mineral properties. The resulting
future income tax liability of $18,858,000 has also been applied to increase the
carrying value of mineral properties. This allocation is preliminary.

    The value of the common shares to be issued by Pan American was estimated
based on the average closing price of Pan American's common shares for the
period before and after the date that the terms of the transaction were agreed
and announced.
