         constating instrument, as applicable) or (B) in default in the
         performance or observance of any obligation, covenant or condition
         contained in any indenture, mortgage, deed of trust, loan agreement,
         lease or other agreement or instrument to which it is a party or by
         which it or any of its properties may be bound (except, in the case of
         clause (B) above, for such defaults which would not result in a
         Material Adverse Effect);

                  (q)    The statements set forth in the Prospectuses under the
         captions "Description of the Notes", insofar as they purport to
         constitute a summary of the terms of the Securities; under the captions
         "Tax Considerations", "Description of Certain Indebtedness" and
         "Underwriting", insofar as they purport to describe the provisions of
         the laws and documents referred to therein, are a fair summary of such
         terms and provisions and insofar as such statements constitute legal
         considerations, are accurate and correct in all material respects;

                  (r)    Except as disclosed in the Prospectuses or as would not
         individually or in the aggregate have a Material Adverse Effect (A) the

         Environmental Laws (as defined herein), (B) the Company and



                                       7
<PAGE>

         its subsidiaries have all permits, authorizations and approvals
         required under any applicable Environmental Laws and are in compliance
         with their requirements, (C) there are no pending or, to the knowledge
         of the Company, threatened Environmental Claims (as defined herein)
         against the Company or any of its subsidiaries, and (D) to the
         knowledge of the Company, there are no circumstances with respect to
         any property or operations of the Company or its subsidiaries that
         could reasonably be anticipated to form the basis of an Environmental
         Claim against the Company or its subsidiaries. In addition, based upon
         the Company's reviews, conducted in the ordinary course of its
         business, of the effect of Environmental Laws on the business and
         operations of the Company and its subsidiaries, the Company has
         reasonably concluded that, except as disclosed in the Prospectuses, the
         costs and liabilities under Environmental Laws (including, without
         limitation, any capital or operating expenditures required for
         clean-up, remediation, closure of properties or compliance with
         Environmental Laws or any permit, license or approval, any related
         constraints on operating activities and potential liabilities to third
         parties) would not, singularly or in the aggregate, have a Material
         Adverse Effect, or be required to be disclosed in the Prospectuses;

         adversely to the Company or any of its subsidiaries, would individually
         or in the aggregate have a Material Adverse Effect; and, to the best of

         Governmental Agency is required to effect payments of principal,
         premium, if any, and interest on the Securities;

                  (v)    No withholding tax imposed under the federal laws of

         Effect;

         aware of any infringement of or conflict with asserted rights of others

         circumstances which would render any Intellectual Property invalid or
         inadequate to protect the interest of the Company or any of its
         subsidiaries therein, and which infringement or conflict (if the
         subject of any unfavorable decision, ruling or finding) or invalidity
         or inadequacy, individually or in the aggregate, would result in a
         Material Adverse Effect;

                  (aa)  Neither the Company nor any of its subsidiaries has
         taken, directly or indirectly, any action which was designed to or
         which has constituted or which might reasonably be expected to cause or
         result in stabilization or manipulation of the price of any security of
         the Company or, except as permitted by this Agreement, facilitate the
         sale or resale of the Securities;

         Company and its consolidated subsidiaries for the periods specified;

         disturbance by the employees of any of its or any subsidiary's

         memorandum (the "CANADIAN OFFERING MEMORANDUM") prepared for such
         purpose, pursuant to exemptions from the prospectus requirements of the

         and will not be, directly or indirectly, invested in or committed to
         any business activities in any of the Prohibited Countries;

         Form 52-109F2 under Multilateral Instrument 52-109 - Certification of
         Disclosures in Issuer's Annual and Interim Filings ('"52-109"), and
         such controls and procedures are effective to ensure that all material
         information concerning the Company is made known, on a timely basis, to
         the individuals responsible for the preparation of the Company's
         filings with the Commission and the BCSC. The Company has disclosed to

         accepted accounting principles and to maintain asset accountability;
         (C) access to assets is permitted only in accordance with management's
         general or specific authorization; and (D) the recorded accountability
         for assets is compared with the existing assets at reasonable intervals
         and appropriate action is taken with respect to any differences; and

                  (kk)  The Company has complied in all material respects with
         the Sarbanes-Oxley Act of 2002 and the corporate governance rules of
         the Nasdaq National Market applicable to it.

         2.   Subject to the terms and conditions herein set forth, the Company

         such order at the earliest possible time; to file promptly all reports
         required to be filed by the Company (i) with the Commission pursuant to

         subsequent to the date of the Prospectuses and for so long as the

         a foreign corporation or to file a general consent to service of
         process in any jurisdiction and further provided that nothing contained
         in this Section 5(b) shall require the Company to file or qualify a
         prospectus in any province or territory of Canada, other than British
         Columbia (for the purpose of qualifying under British Columbia

                  or as a foreign corporation for the transaction of business
                  under the laws of each other jurisdiction in which it owns or
                  leases properties or conducts any business so as to require
                  such qualification, or is subject to no material liability or
                  disability by reason of the failure to be so qualified in any
                  such jurisdiction (such counsel being entitled to rely in
                  respect of the opinion in this clause upon opinions of local
                  counsel and in respect of matters of fact upon certificates of
                  officers of the Company, provided that such counsel shall
                  state that they believe that both you and they are justified
                  in relying upon such opinions);

                         (iv)   To such counsel's knowledge, based solely upon
                  documents provided to such counsel by the Company and
                  conferences with officers and other representatives of the
                  Company in connection with the offering of the Securities, and
                  other than as set forth in the Prospectuses, and any amendment
                  or supplement thereto, there are no legal or governmental
                  proceedings pending to which the Company or any of its
                  subsidiaries is a party or of which any property of the
                  Company or any of its subsidiaries is the subject which are of
                  a character required by the British Columbia Securities Laws
                  to be described or referred to in the Prospectuses and any
                  amendment or supplement thereto, and no such proceedings are
                  threatened or contemplated by any Governmental Agency or
                  threatened by others;

                         (v)    This Agreement has been duly authorized and, to
                  the extent that execution and delivery are governed by the
                  laws of the Province of British Columbia and the federal laws
                  of Canada applicable therein, executed and delivered by the
                  Company;

                         (vi)   The Indenture and the Securities have been duly
                  authorized and, to the extent that execution, issuance and
                  delivery are matters governed by the laws of the Province of
                  British Columbia and the federal laws of Canada applicable
                  therein, the Indenture has been duly executed and delivered by
                  the Company and the Securities have been duly executed, issued
                  and delivered by the Company; and the Securities and the
                  Indenture conform in all material respects to the descriptions
                  thereof in the Prospectuses as amended or supplemented;


                                       20

                         (vii)  The form of global certificate representing the
                  Securities, as included in the Indenture, has been duly
                  approved and adopted by the Company and complies in all
                  material respects with all applicable statutory requirements
                  of the Province of British Columbia and of Canada applicable
                  therein and with any applicable requirements of the constating
                  documents of the Company;

                         (viii) The Indenture and the issuance of the Securities
                  thereunder comply, to the extent applicable, with the
                  provisions of the Canada Business Corporations Act. No
                  registration, filing or recording of the Indenture under
                  British Columbia Securities Laws is necessary in order to
                  preserve or protect the validity or enforceability of the
                  Indenture or the Securities issued thereunder;

                         (ix)   The issue and sale of the Securities and the
                  compliance by the Company with all of the provisions of the
                  Securities, the Indenture and this Agreement and the
                  consummation by the Company of the transactions herein and
                  therein contemplated will not (A) conflict with or result in a
                  breach or violation of any of the terms or provisions of, or
                  constitute a default under, any of the agreements or
                  instruments set forth in the Company's officer's certificate
                  prepared in support of such counsel's opinion and delivered in
                  draft form to counsel for the Underwriters prior to the
                  execution of this Agreement, (B) result in any violation of
                  the provisions of the Articles of Continuance or the By-laws,
                  as amended of the Company or (C) contravene any federal,
                  provincial or local law, rule or regulation of the Province of
                  British Columbia or Canada applicable to the transactions
                  contemplated by the issue and sale of the Securities or the
                  provisions of the Indenture or this Agreement or, to the best
                  of such counsel's knowledge, any order applicable to the
                  Company of any court or of any other governmental body or
                  instrumentality having jurisdiction over it or any of its
                  property that would have a Material Adverse Effect (it being
                  understood that for the purpose of the opinion in this clause
                  (C), such counsel is not passing upon compliance with respect
                  to antifraud or similar provisions of any securities laws of
                  the Province of British Columbia or the Federal laws of Canada
                  applicable therein);

                         (x)    No Governmental Authorization of or with any
                  Governmental Agency in Canada is required for the issue and
                  sale of the Securities or the consummation by the Company of
                  the transactions contemplated by this Agreement or the
                  Indenture, except such as have been obtained;

                         (xi)   To such counsel's knowledge, the Company is not
                  in violation of its constating documents or in default in the
                  performance or observance of any material obligation, covenant
                  or condition contained in any of the agreements or instruments
                  set forth in the Company's officer's certificate prepared in
                  support of such counsel's opinion and delivered in draft form
                  to counsel for the Underwriters prior to the execution of this
                  Agreement;


                                       21
<PAGE>

                         (xii)  To such counsel's knowledge, all descriptions in
                  the Prospectuses as amended or supplemented of contracts,
                  agreements, arrangements and other documents to which the
                  Company or its subsidiaries are a party are correct in all
                  material respects;

                         (xiii) The information in the Registration Statement
                  under "Part II - Indemnification of Directors and Officers"
                  and the statements set forth in the Prospectuses under the
                  captions "Risk Factors -- Risks Related to the Notes and Our
                  Structure -- "It may be difficult for you...", "Description of
                  the Notes -- Enforceability of Judgments", and "Tax
                  Considerations -- Certain Canadian Federal Income Tax
                  Considerations", insofar as they purport to describe the
                  provisions of the laws of the Province of British Columbia or
                  the federal laws of Canada applicable therein, and under the
                  captions "Underwriting" and "Description of Certain
                  Indebtedness" have been reviewed by such counsel and, to the
                  extent that such statements constitute matters of law or legal
                  conclusions, such statements fairly present the information
                  disclosed therein and, insofar as such statements purport to
                  describe the provisions of laws or documents referred to
                  therein, such statements are correct in all material respects;

                         (xiv)  Insofar as matters of the laws of the Province
                  of British Columbia and the federal laws of Canada applicable
                  therein are concerned, the Registration Statement and the
                  filing of the Registration Statement with the Commission have
                  been duly authorized by and on behalf of the Company; and the
                  Registration Statement has been duly executed pursuant to such
                  authorization by and on behalf of the Company;

                         (xv)   A final receipt has been obtained in respect of
                  the Base PREP Prospectus from the BCSC and, subject to the
                  filing of standard post closing notices, all necessary
                  documents have been filed, all necessary proceedings have been
                  taken and all necessary authorizations, approvals, permits and
                  consents have been obtained under British Columbia Securities
                  Laws to permit the Securities to be offered, sold and
                  delivered, as contemplated by this Agreement and pursuant to
                  the U.S./Canada Multi-Jurisdictional Disclosure System
                  ("MJDS"), in the United States, and no other Governmental
                  Authorization of or with any Governmental Agency in Canada or
                  the Province of British Columbia is required for such
                  offering, sale or delivery of the Securities pursuant to the
                  MJDS in the United States or the consummation by the Company
                  of the transactions contemplated by this Agreement, except
                  such as have been obtained;

                         (xvi)  The Company is a "Reporting issuer" under the
                  securities legislation of the Province of British Columbia and
                  is not on the list of defaulting issuers maintained under such
                  legislation; and the Company meets the general requirements to
                  use a short form prospectus under National Instrument
                  44-101-Short Form Prospectus Distributions;

                         (xvii) To such counsel's knowledge, there are no
                  franchises, contracts, indentures, mortgages, loan agreements,
                  notes, leases or other instruments that in



                                       22
<PAGE>

                  accordance with the requirements of the BCSC are required to
                  be made publicly available in connection with the offering of
                  the Securities that have not been made publicly available as
                  would be required; and there are no documents required to be
                  filed with the BCSC in connection with the offering of the
                  Securities that have not been filed as required;

                         (xviii) No withholding tax imposed under the federal
                  laws of Canada or the laws of the Province of British Columbia
                  will be payable in respect of the payment of the commissions
                  contemplated by this Agreement by the Company to an
                  Underwriter, provided that the Underwriter deals at arm's
                  length with the Company (as such term is understood for
                  purposes of the Income Tax Act (Canada)), and that such
                  commissions are payable in respect of services rendered by the
                  Underwriter wholly outside of Canada that are performed in the
                  ordinary course of business carried on by the Underwriter that
                  includes the performance of such services for a fee and any
                  such amount is reasonable in the circumstances;

                         (xix)  No goods and services tax imposed under the
                  federal laws of Canada will be payable by the Company in
                  respect of the payment of commissions as contemplated by this
                  Agreement to an Underwriter, provided that such commissions
                  are in respect of services performed by an Underwriter wholly
                  outside of Canada;

                         (xx)   No stamp duty, documentary taxes or similar
                  taxes are payable by the Company under the federal laws of
                  Canada or the laws of the Province of British Columbia in
                  connection with the sale and delivery of the Securities
                  pursuant to this Agreement by the Company;

                         (xxi)  A court of competent jurisdiction in the
                  Province of British Columbia (a "BRITISH COLUMBIA COURT")
                  would give effect to the choice of the law of the State of New
                  York ("NEW YORK LAW") as the proper law governing this
                  Agreement, the Indenture and the Securities, provided that
                  such choice of law is: (A) bona fide (primarily in the sense
                  that it was not made with a view to avoiding the consequences
                  of the laws of any other jurisdiction); (B) legal; and (C) not
                  contrary to public policy as that term is applied by a British
                  Columbia Court ("PUBLIC POLICY"). To such counsel's knowledge,
                  no Public Policy would be offended by recognition of this
                  choice of law, nor are we aware of any basis upon which such
                  choice of law would not be bonafide and legal;

                         (xxii) In an action on a final and conclusive judgment
                  in personam of any federal or state court in the State of New
                  York (a "NEW YORK COURT") that is not impeachable as void or
                  voidable under New York law, a British Columbia Court would
                  give effect to the appointment by the Company of CT
                  Corporation System as its agent to receive service of process
                  in the United States of America under this Agreement and the
                  Indenture and to the provisions in this Agreement and the
                  Indenture whereby the



                                       23
<PAGE>

                  Company submits to the non-exclusive jurisdiction of a New
                  York Court, except that a British Columbia Court may not
                  consider itself bound by any provision of this Agreement or
                  the Indenture purporting to make that submission to
                  jurisdiction exclusive;

                         (xxiii) If this Agreement, the Indenture or the
                  Securities are sought to be enforced in the Province of
                  British Columbia in accordance with the laws applicable
                  thereto as chosen by the parties, namely New York law, a
                  British Columbia Court would, subject to paragraph (xxi)
                  above, recognize the choice of New York law and, upon such law
                  being specifically pleaded and appropriate evidence as to such
                  law being adduced, apply such law to all issues that under the
                  conflict rules of the Province of British Columbia, are to be
                  determined in accordance with the proper or governing law of
                  the contract, provided that: (A) none of the provisions of
                  this Agreement, the Indenture or the Securities, as the case
                  may be, or of applicable New York law, are contrary to Public
                  Policy; (B) such New York law does not constitute, directly or
                  indirectly, revenue, expropriatory, public or penal laws; (C)
                  in matters of procedure, the laws of the Province of British
                  Columbia will be applied; (D) a British Columbia Court will
                  retain discretion to decline to hear such action if it is
                  contrary to Public Policy for it to do so, or if it is not the
                  appropriate forum to hear such an action, or if concurrent
                  proceedings are being brought elsewhere; and (E) a British
                  Columbia Court may not enforce an obligation enforceable under
                  the laws of the Province of British Columbia where performance
                  of the obligation would be illegal under the laws of the place
                  of performance;

                         (xxiv) The laws of the Province of British Columbia and
                  the federal laws of Canada applicable therein permit an action
                  to be brought in a British Columbia Court on a final and
                  conclusive judgment in personam of a New York Court that is
                  subsisting and unsatisfied respecting the enforcement of this
                  Agreement, the Indenture or the Securities, that is not
                  impeachable as void or voidable under New York law and that is
                  for a sum certain if: (A) the New York Court that rendered
                  such judgment had jurisdiction over the judgment debtor, as
                  recognized by a British Columbia Court (and submission by the
                  Company in this Agreement and the Indenture to the
                  jurisdiction of the New York Court will be deemed sufficient
                  for such purpose); (B) proper service of process in respect of
                  the proceeding in which such judgment was obtained was made in
                  accordance with New York law; (C) such judgment was not
                  obtained by fraud or in a manner contrary to natural justice
                  and the enforcement thereof would not be inconsistent with
                  Public Policy or contrary to any order made by the Attorney
                  General of Canada under the Foreign Extraterritorial Measures
                  Act (Canada) or contrary to any order made by the Competition
                  Tribunal under the Competition Act (Canada); (D) the
                  enforcement of such judgment in British Columbia does not
                  constitute, directly or indirectly, the enforcement of any
                  laws of the State of New York or of the United States of
                  America which a British Columbia Court would characterize as
                  revenue, expropriatory, public or penal laws; (E) in an action
                  to enforce a default judgment, the judgment does not



                                       24
<PAGE>

                  contain a manifest error on its face; (F) the action to
                  enforce such judgment is commenced within the applicable
                  limitation period after the date of such judgment; and (G) the
                  judgment does not conflict with another final and conclusive
                  judgment in the same cause of action, provided that a British
                  Columbia Court may stay an action to enforce a foreign
                  judgment if an appeal of a judgment is pending or the time for

                  incorporated therein or omitted therefrom, as to which such
                  counsel need express no opinion) appear on their face to be

                  to the requirements, including the PREP Procedures, of the

                  issue, sale and delivery of the Securities by the Company or
                  the Underwriters to purchasers resident in the Designated
                  Provinces, either through registrants or dealers registered
                  under applicable laws who comply with such applicable laws or
                  in circumstances in which there is an exemption from the
                  registration requirements of the applicable laws, except such
                  filings as may be required after the Time of Delivery under

                  although they are not passing upon and do not assume any
                  responsibility for the accuracy, completeness or fairness of
                  the statements contained in the Registration Statement or the
                  Prospectuses, except for those referred to in the opinion in

                  xiii of this Section 7(d), such counsel has no reason to
                  believe that, as of its effective date, the Registration
                  Statement or any further amendment thereto made by the Company
                  prior to the Time of Delivery (other than the financial
                  statements and related schedules therein, as to which such
                  counsel need express no opinion) contained an untrue statement
                  of a material fact or omitted to state a material fact
                  required to be stated therein or necessary to make the
                  statements therein not misleading or that, as of their dates,
                  the Prospectuses or any further amendment or supplement
                  thereto made by the Company prior to the Time of Delivery
                  (other than the financial statements and related schedules
                  therein, as to which such counsel need express no opinion)
                  contained an untrue statement of a material fact or omitted to
                  state a material fact necessary to make the statements
                  therein, in the light of the circumstances under which they
                  were made, not misleading or that, as of the Time of Delivery,
                  the Prospectuses or any further amendment or supplement
                  thereto made by the Company prior to the Time of Delivery
                  (other than the financial statements and related schedules
                  therein, as to which such counsel need express no opinion)
                  contains an untrue statement of a material fact or omits to
                  state a material fact necessary to make the statements
                  therein, in the light of the circumstances under which they
                  were made, not misleading;

                  In giving such opinion, such counsel may rely, as to all
                  matters governed by the laws of jurisdictions other than the
                  laws of the Provinces of British Columbia, Alberta, Ontario
                  and Quebec and the federal laws of Canada applicable therein,
                  upon opinions of local counsel, who shall be counsel
                  satisfactory to counsel for the Underwriters, in which case
                  the opinion shall state that they believe the Underwriters and
                  they are entitled to so rely. Such counsel may also state
                  that, insofar as such opinion involves factual matters, they
                  have relied, to the extent they deem proper, upon certificates
                  of officers of the Company and certificates of public
                  officials; provided that such certificates have been delivered
                  to the Underwriters. Such opinion may be subject to
                  assumptions, qualifications and limitations as are reasonable
                  and customary in legal opinions of this type and as shall be
                  satisfactory to counsel for the Underwriters but shall not
                  state that it is to be governed or qualified by, or that it is
                  otherwise subject to, any treatise, written policy or other
                  document relating to legal opinions.

                  will not result in any violation of the Memorandum and
                  Articles of Association of MIHL, and do not and will not
                  conflict with, or result in a breach of any of the terms or
                  provisions of (i) any existing applicable Cayman Islands
                  statute, regulation or rule; or (ii) to such counsel's
                  knowledge, any order or decree of any Cayman Islands
                  government, governmental, regulatory or administration agency,
                  authority, commission or instrumentality having jurisdiction
                  over MIHL or any of its properties or assets;

                         (iv)   MIHL has not failed to obtain any licence,
                  permit, franchise or other administrative, governmental or
                  regulatory approval in the Cayman Islands necessary to the
                  ownership of its property or to the conduct of its business,
                  which failure to obtain has or could have a material adverse
                  effect on the business of MIHL;

                         (v)    Based solely on such counsel's search of the

                  George Town, Grand Cayman on or immediately prior to the Time
                  of Delivery and on a certificate of the Secretary of MIHL in
                  support of such counsel's opinion, a copy of which shall be
                  provided to you, MIHL is not the subject of any legal
                  proceedings before any Court of the Cayman Islands; there is
                  no mechanism for identifying whether MIHL is the subject of
                  proceedings before any arbitrator or governmental body in the
                  Cayman Islands, but such counsel has not been informed or
                  notified of any such proceedings.

                  The opinion shall make reference to, and have annexed, a
                  certified true copy of the Register of Members of MIHL,
                  showing who are the current shareholders of MIHL as of the
                  Time of Delivery.

                  (k)    On the date of the Prospectuses at a time prior to the

         amendment to the Registration Statement filed subsequent to the date of
         this Agreement and also at the Time of Delivery, KPMG LLP shall have
         furnished to you a letter or letters, dated the respective dates of
         delivery thereof, in form and substance satisfactory to you, to the
         effect set forth in Annex I hereto (the executed copy of the letter
         delivered prior to the execution of this Agreement is attached as Annex
         I(a) hereto and a draft of the form of letter to be delivered on the
         effective date of any post-effective amendment to the Registration
         Statement and as of each Time of Delivery is attached as Annex I(b)
         hereto);

                  (l)    (i) Neither the Company nor any of its subsidiaries
         shall have sustained since the date of the latest audited financial
         statements included or incorporated by reference in the Prospectuses
         any loss or interference with its business from fire, explosion, flood
         or other calamity, whether or not covered by insurance, or from any
         labor dispute or court or governmental action, order or decree,
         otherwise than as set forth or contemplated in the Prospectuses, and
         (ii) since the respective dates as of which information is given in the
         Prospectuses there shall not have been any change in the share capital
         or long-term debt of the Company or any of its subsidiaries or any
         change, or any development involving a prospective change, in or
         affecting the general affairs, management, financial position,
         shareholders' equity or results of operations of the Company and its
         subsidiaries taken as a whole, otherwise than as set forth or
         contemplated in the Prospectus, the effect of which, in any such case
         described in clause (i) or (ii), is in the judgment of the Underwriters
         so material and adverse as to make it impracticable or inadvisable to
         proceed with the public offering or the delivery of the Securities on
         the terms and in the manner contemplated in the Prospectuses;

                  (m)    On or after the date hereof (i) no downgrading shall
         have occurred in the rating accorded the Company's debt securities by
         any "nationally recognized statistical rating organization", as that
         term is defined by the Commission for purposes of Rule 436(g)(2) under
         the Act, and (ii) no such organization shall have publicly announced
         that it has under surveillance or review, with possible negative
         implications, its rating of any of the Company's debt securities;

                  (n)    On or after the date hereof there shall not have
         occurred any of the following: (i) a suspension or material limitation
         in trading in securities generally on the Nasdaq National Market
         ("NASDAQ"), or the New York Stock Exchange ("NYSE"), or The Toronto
         Stock Exchange (the "TSX"); (ii) a suspension or material limitation in
         trading in the Company's securities on Nasdaq or the TSX; (iii) a
         general moratorium on commercial banking activities in New York or
         Canada declared by the relevant authorities, or a material disruption
         in commercial banking or securities settlement or clearance services in
         the United States or Canada; (iv) a change or development involving a
         prospective change in Canada taxation affecting the Company, the
         Securities or the transfer thereof or (v) the outbreak or escalation of
         hostilities involving the United States or Canada or the declaration by
         the United States or Canada of a national emergency or war or (vi) the
         occurrence of any other calamity or crisis or any change in financial,
         political or economic conditions or currency exchange rates or controls
         in the United States, Canada or elsewhere, if the effect of any such
         event specified in clause (v)



                                       35
<PAGE>

         or (vi) in the judgment of the Underwriters makes it impracticable or
         inadvisable to proceed with the public offering or the delivery of the
         Securities on the terms and in the manner contemplated in the
         Prospectuses;

                  (o)    The Company shall have complied with the provisions of
         Section 5(c) hereof with respect to the furnishing of prospectuses on
         the New York Business Day next succeeding the date of this Agreement;
         and

                  (p)    The Company shall have furnished or caused to be
         furnished to you at the Time of Delivery certificates of officers of
         the Company satisfactory to you as to the accuracy of the
         representations and warranties of the Company herein at and as of such
         Time of Delivery, as to the performance by the Company of all of its
         obligations hereunder to be performed at or prior to such Time of
         Delivery, as to the matters set forth in subsections (a) and (l) of
         this Section and as to such other matters as you may reasonably
         request.

         8.       (a) The Company will indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the Act, any
British Columbia Securities Laws or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in any preliminary prospectus, the Registration Statement (including
PREP Information), the U.S. Prospectus or the Canadian Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse each Underwriter for any legal or other expenses reasonably incurred
by such Underwriter in connection with investigating or defending any such
action or claim as such expenses are incurred; provided, however, that the
Company shall not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any preliminary
prospectus, the Registration Statement (including the PREP Information), the
U.S. Prospectus or the Canadian Prospectus or any such amendment or supplement
in reliance upon and in conformity with written information furnished to the
Company by any Underwriter through ABN AMRO Incorporated or BNP Paribas
Securities Corp. expressly for use therein.

         (b)    Each Underwriter will indemnify and hold harmless the Company
against any losses, claims, damages or liabilities to which the Company may
become subject, under the Act, any British Columbia Securities Laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any preliminary prospectus, the
Registration Statement (including the PREP Information), the U.S. Prospectus or
the Canadian Prospectus, or any amendment or supplement thereto, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, in each case to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission was
made in any preliminary prospectus, the


                                       36
<PAGE>

Registration Statement (including the PREP Information), the U.S. Prospectus or
the Canadian Prospectus or any such amendment or supplement in reliance upon and
in conformity with written information furnished to the Company by such
Underwriter through ABN AMRO Incorporated or BNP Paribas Securities Corp.
expressly for use therein; and will reimburse the Company for any legal or other
expenses reasonably incurred by the Company in connection with investigating or
defending any such action or claim as such expenses are incurred.

         (c)    Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who shall not,
except with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party under such subsection for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified party is an actual or
potential party to such action or claim) unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act, by or
on behalf of any indemnified party.

         (d)    If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Underwriters
on the other from the offering of the Securities. If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law or if the indemnified party failed to give the notice required under
subsection (c) above, then each indemnifying party shall contribute to such
amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and the Underwriters on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other shall be



                                       37
<PAGE>

deemed to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectuses. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company on the one hand or the Underwriters on the other and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and the Underwriters agree that
it would not be just and equitable if contribution pursuant to this subsection
(d) were determined by pro rata allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to above in
this subsection (d). The amount paid or payable by an indemnified party as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above in this subsection (d) shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (d), no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations in this subsection
(d) to contribute are several in proportion to their respective underwriting
obligations and not joint.

         (e)    The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company (including any
person who, with his or her consent, is named in the Registration Statement as
about to become a director of the Company) and to each person, if any, who
controls the Company within the meaning of the Act.

         9.    (a) If any Underwriter shall default in its obligation to
purchase the Securities which it has agreed to purchase hereunder, you may in
your discretion arrange for you or another party or other parties to purchase
such Securities on the terms contained herein. If within thirty-six hours after
such default by any Underwriter you do not arrange for the purchase of such
Securities, then the Company shall be entitled to a further period of thirty-six
hours within which to procure another party or other parties satisfactory to you
to purchase such Securities on such terms. In the event that, within the
respective prescribed periods, you notify the Company that you have so arranged
for the purchase of such Securities, or the Company notifies you that it has so
arranged for the purchase of such Securities, you or the Company shall have the
right to postpone the Time of Delivery for a period of not more than seven days,
in order to effect whatever changes may thereby be made necessary in the
Registration



                                       38
<PAGE>

Statement or the Prospectuses, or in any other documents or arrangements, and
the Company agrees to file promptly any amendments to the Registration Statement
or the Prospectuses which in your opinion may thereby be made necessary. The
term "Underwriter" as used in this Agreement shall include any person
substituted under this Section with like effect as if such person had originally
been a party to this Agreement with respect to such Securities.

         (b)    If, after giving effect to any arrangements for the purchase of
the Securities of a defaulting Underwriter or Underwriters by you and the
Company as provided in subsection (a) above, the aggregate principal amount of
such Securities which remains unpurchased does not exceed one-eleventh of the
aggregate principal amount of all the Securities, then the Company shall have
the right to require each non-defaulting Underwriter to purchase the principal
amount of Securities which such Underwriter agreed to purchase hereunder and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the principal amount of Securities which such Underwriter agreed
to purchase hereunder) of the Securities of such defaulting Underwriter or
Underwriters for which such arrangements have not been made; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

         (c)    If, after giving effect to any arrangements for the purchase of
the Securities of a defaulting Underwriter or Underwriters by you and the
Company as provided in subsection (a) above, the aggregate principal amount of
Securities which remains unpurchased exceeds one-eleventh of the aggregate
principal amount of all the Securities, or if the Company shall not exercise the
right described in subsection (b) above to require non-defaulting Underwriters
to purchase Securities of a defaulting Underwriter or Underwriters, then this
Agreement shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company, except for the expenses to be borne
by the Company and the Underwriters as provided in Section 6 hereof and the
indemnity and contribution agreements in Section 8 hereof; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

         10.    The respective indemnities, agreements, representations,
warranties and other statements of the Company and the several Underwriters, as
set forth in this Agreement or made by or on behalf of them, respectively,
pursuant to this Agreement, shall remain in full force and effect, regardless of
any investigation (or any statement as to the results thereof) made by or on
behalf of any Underwriter or any controlling person of any Underwriter, or the
Company, or any officer or director or controlling person of the Company, and
shall survive delivery of and payment for the Securities.

         11.    If this Agreement shall be terminated pursuant to Section 9
hereof, the Company shall not then be under any liability to any Underwriter
except as provided in Sections 6 and 8 hereof; but, if for any other reason, the
Securities are not delivered by or on behalf of the Company as provided herein,
the Company will reimburse the Underwriters through you for all out-of-pocket
expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Underwriters in making preparations for the
purchase, sale and delivery of the Securities, but the Company shall then be
under no further liability to any Underwriter except as provided in Sections 6
and 8 hereof.


                                       39
<PAGE>

         12.    In all dealings hereunder, you shall act on behalf of each of
the Underwriters, and the parties hereto shall be entitled to act and rely upon
any statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by ABN AMRO Incorporated or BNP Paribas Securities Corp.
on behalf of the Underwriters.

         All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of ABN AMRO
Incorporated, 55 East 52nd Street, 6th Floor, New York, NY 10055, Attention:
Syndicate Desk, Liz Chan, Fax: (212) 409-5256 and BNP Paribas Securities Corp.,
787 Seventh Avenue, 8th Floor, New York, NY 10019-6016, Attention: Tim McCann,
Fax: (212) 841-3158; and if to the Company shall be delivered or sent by mail,
telex or facsimile transmission to the address of the Company set forth in the
Registration Statement, Attention: Chief Financial Officer; provided, however,
that any notice to an Underwriter pursuant to Section 8(c) hereof shall be
delivered or sent by mail, telex or facsimile transmission to such Underwriter
at its address set forth in its Underwriters' Questionnaire, or telex
constituting such Questionnaire, which address will be supplied to the Company
by you upon request. Any such statements, requests, notices or agreements shall
take effect upon receipt thereof.

         13.    This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Company and, to the extent provided in
Sections 8 and 10 hereof, the officers and directors of the Company and each
person who controls the Company or any Underwriter, and their respective heirs,
executors, administrators, successors and assigns, and no other person shall
acquire or have any right under or by virtue of this Agreement. No purchaser of
any of the Securities from any Underwriter shall be deemed a successor or assign
by reason merely of such purchase.

         14.    The Company irrevocably (i) agrees that any legal suit, action
or proceeding against the Company brought by any Underwriter or by any person
who controls any Underwriter arising out of or based upon this Agreement or the
transactions contemplated hereby may be instituted in any New York Court, (ii)
waives, to the fullest extent it may effectively do so, any objection which it
may now or hereafter have to the laying of venue of any such proceeding and
(iii) submits to the exclusive jurisdiction of such courts in any such suit,
action or proceeding. The Company irrevocably waives any immunity to
jurisdiction to which it may otherwise be entitled or become entitled (including
sovereign immunity, immunity to pre-judgment attachment, post-judgment
attachment and execution) in any legal suit, action or proceeding against it
arising out of or based on this Agreement or the transactions contemplated
hereby which is instituted in any New York Court or in any competent court in
Canada. The Company has appointed CT Corporation System 111 Eighth Avenue, New
York, New York 10011, as its authorized agent (the "AUTHORIZED AGENT") upon whom
process may be served in any such action arising out of or based on this
Agreement or the transactions contemplated hereby which may be instituted in any
New York Court by any Underwriter or by any person who controls any Underwriter,
expressly consents to the jurisdiction of any such court in respect of any such
action, and waives any other requirements of or objections to personal
jurisdiction with respect thereto. Such appointment shall be irrevocable. The
Company represents and warrants that the Authorized Agent has agreed to act as
such agent for service of process and agrees to take any and all action,
including the



                                       40
<PAGE>

filing of any and all documents and instruments, that may be necessary to
continue such appointment in full force and effect as aforesaid. Service of
process upon the Authorized Agent and written notice of such service to the
Company shall be deemed, in every respect, effective service of process upon the
Company.

         15.    In respect of any judgment or order given or made for any amount
due hereunder that is expressed and paid in a currency (the "JUDGMENT CURRENCY")
other than United States dollars, the Company will indemnify each Underwriter
against any loss incurred by such Underwriter as a result of any variation as
between (i) the rate of exchange at which the United States dollar amount is
converted into the judgment currency for the purpose of such judgment or order
and (ii) the rate of exchange at which an Underwriter is able to purchase United
States dollars with the amount of judgment currency actually received by such
Underwriter. The foregoing indemnity shall constitute a separate and independent
obligation of the Company and shall continue in full force and effect
notwithstanding any such judgment or order as aforesaid. The term "RATE OF
EXCHANGE" shall include any premiums and costs of exchange payable in connection
with the purchase of or conversion into United States dollars.

         16.    Time shall be of the essence of this Agreement. As used herein,
and except as otherwise provided, the term "BUSINESS DAY" shall mean any day
when the Commission's office in Washington, D.C. is open for business.

         17.    THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK.

         18.    This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such respective counterparts shall together constitute one and
the same instrument.

         19.    The Company is authorized, subject to applicable law, to
disclose any and all aspects of this potential transaction that are necessary to
support any U.S. federal income tax benefits expected to be claimed with respect
to such transaction, and all materials of any kind (including tax opinions and
other tax analyses) related to those benefits, without the Underwriters imposing
any limitation of any kind.

                  FORM OF ANNEX I DESCRIPTION OF COMFORT LETTER


         Pursuant to Section 7(j) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

                  (i) They are independent certified public accountants with
         respect to the Company and its subsidiaries within the meaning British
         Columbia Securities Laws, the Act and the applicable published rules
         and regulations thereunder (collectively, the "ACCOUNTING
         REQUIREMENTS");

                  (ii) In their opinion, the financial statements and any
         supplementary financial information and schedules (and, if applicable,
         financial forecasts and/or pro forma financial information) audited by
         them and included in the Prospectuses and the Registration Statement
         comply as to form in all material respects with the Accounting
         Requirements and, if applicable, they have made a review in accordance
         with standards established by the Canadian Institute of Chartered
         Accountants ("CICA"), which are substantially similar to those of the
         American Institute of Certified Public Accountants ("AICPA") of the
         unaudited consolidated interim financial statements, and if applicable,
         selected financial data, pro forma financial information, financial
         forecasts and/or condensed financial statements derived from audited
         financial statements of the Company for the periods specified in such
         letter, as indicated in their reports thereon, copies of which have
         been separately furnished to the representatives of the Underwriters
         (the "REPRESENTATIVES") and are attached hereto;

                  (iii) They have made a review in accordance with standards
         established by CICA, which are substantially similar to those of AICPA
         of the unaudited condensed consolidated statements of income,
         consolidated balance sheets and consolidated statements of cash flows
         included in the Prospectuses and on the basis of specified procedures
         including inquiries of officials of the Company who have responsibility
         for financial and accounting matters regarding whether the unaudited
         condensed consolidated financial statements referred to in paragraph
         (vi)(A)(i) below comply as to form in all material respects with the
         Accounting Requirements, nothing came to their attention that cause
         them to believe that the unaudited condensed consolidated financial
         statements do not comply as to form in all material respects with the
         Accounting Requirements;

                  (iv) The unaudited selected financial information with respect
         to the consolidated results of operations and financial position of the
         Company for the five most recent fiscal years included in the
         Prospectuses agrees with the corresponding amounts (after restatements
         where applicable) in the audited consolidated financial statements for
         such five fiscal years which

         were included or incorporated by reference in the Company's Annual
         Reports on Form 40-F or Annual Information Form for such fiscal years;

                  (v) On the basis of limited procedures, not constituting an
         examination in accordance with generally accepted auditing standards,
         consisting as applicable in the circumstances of a reading of the
         unaudited financial statements and other information referred to below,
         a reading of the latest available interim financial statements of the
         Company and its subsidiaries, inspection of the minute books of the
         Company and its subsidiaries since the date of the latest audited
         financial statements included in the Prospectuses, inquiries of
         officials of the Company and its subsidiaries responsible for financial
         and accounting matters and such other inquiries and procedures as may
         be specified in such letter, nothing came to their attention that
         caused them to believe that:

                           (A) (i) the unaudited consolidated statements of
                  income, consolidated balance sheets and consolidated
                  statements of cash flows included in the Prospectuses do not
                  comply as to form in all material respects with the Accounting
                  Requirements, or (ii) any material modifications should be
                  made to the unaudited condensed consolidated statements of
                  income, consolidated balance sheets and consolidated
                  statements of cash flows included in the Prospectuses for them
                  to be in conformity with Canadian GAAP applicant on the basis
                  substantially consistent with that of the audited financial
                  statements in the Prospectuses;

                           (B) any other unaudited income statement data and
                  balance sheet items included in the Prospectuses do not agree
                  with the corresponding items in the unaudited consolidated
                  financial statements from which such data and items were
                  derived, and any such unaudited data and items were not
                  determined on a basis substantially consistent with the basis
                  for the corresponding amounts in the audited consolidated
                  financial statements included in the Prospectuses;

                           (C) if applicable, any unaudited pro forma
                  consolidated condensed financial statements included in the
                  Prospectuses do not comply as to form in all material respects
                  with the Accounting Requirements or the pro forma adjustments
                  have not been properly applied to the historical amounts in
                  the compilation of those statements;

                           (D) as of a specified date not more than five days
                  prior to the date of such letter, there have been no changes
                  in the consolidated capital stock (other than issuances of
                  capital stock upon exercise of options and stock appreciation
                  rights, upon earn-outs of performance shares and upon
                  conversions of convertible securities, in each case which were
                  outstanding on the date of the latest financial statements
                  included in the Prospectuses) or any increase in the
                  consolidated long-term debt of the Company and its
                  subsidiaries, or any decreases in consolidated net current
                  assets or stockholders' equity or other items specified by the
                  Representatives, or any increases in any items specified by
                  the Representatives, in each case as compared with amounts
                  shown in the latest


                                    Annex I-2

<PAGE>


                  balance sheet included in the Prospectus, except in each case
                  for changes, increases or decreases which the Prospectus
                  disclose have occurred or may occur or which are described in
                  such letter; and


                           (E) for the period from the date of the latest
                  financial statements included in the Prospectuses to the
                  specified date referred to in clause (E) there were no
                  decreases in consolidated net revenues or operating profit or
                  the total or per share amounts of consolidated net income or
                  other items specified by the Representatives, or any increases
                  in any items specified by the Representatives, in each case as
                  compared with the comparable period of the preceding year and
                  with any other period of corresponding length specified by the
                  Representatives, except in each case for decreases or
                  increases which the Prospectuses discloses have occurred or
                  may occur or which are described in such letter; and

                  (i) In addition to the examination referred to in their
         report(s) included in the Prospectuses and the limited procedures,
         inspection of minute books, inquiries and other procedures referred to
         in paragraphs (iii) and (vi) above, they have carried out certain
         specified procedures, not constituting an examination in accordance
         with generally accepted auditing standards, with respect to certain
         amounts, percentages and financial information specified by the
         Representatives, which are derived from the general accounting records
         of the Company and its subsidiaries, which appear in the Prospectuses,
         or in Part II of, or in exhibits and schedules to, the Registration
         Statement specified by the Representatives, and have compared certain
         of such amounts, percentages and financial information with the
         accounting records of the Company and its subsidiaries and have found
         them to be in agreement.
