Dear Sirs:

                  Sierra Wireless, Inc. (the "COMPANY"), a corporation
incorporated in Canada under the CANADA BUSINESS CORPORATIONS ACT and certain
shareholders of the Company named in Schedule 2 hereto (the "SELLING
SHAREHOLDERS"), propose to sell an aggregate of 4,000,000 common shares (the
"FIRM SHARES") in the capital of the Company (the "COMMON SHARES"). Of the
4,000,000 Firm Shares, 3,842,222 are being sold by the Company and 157,778 are
being sold by the Selling Shareholders. In addition, the Company proposes to
grant to the Underwriters named in Schedule 1 hereto (the "UNDERWRITERS") an
option to purchase up to an additional 600,000 Common Shares on the terms and
for the purposes set forth in Section 3 (the "OPTION SHARES"). The Firm Shares
and the Option Shares, if purchased, are hereinafter collectively called the
"SHARES." This is to confirm the agreement concerning the purchase of the Shares
from the Company and the Selling Shareholders by the Underwriters.

         1. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE COMPANY AND THE
SUBSIDIARIES. The Company and each of the entities listed on Schedule 3 (each, a
"SUBSIDIARY" and collectively, the "SUBSIDIARIES"), jointly and severally,
represent, warrant and agree that:

         (a) The Company has prepared and filed with the British Columbia
     Securities Commission in the Province of British Columbia, Canada (the
     "PRINCIPAL CANADIAN REGULATOR") and with the securities regulatory
     authorities (the "CANADIAN SECURITIES REGULATORY AUTHORITIES") in the
     Provinces of Alberta, Saskatchewan, Manitoba, Ontario, Quebec, Nova Scotia,
     New Brunswick, Prince Edward Island and Newfoundland and Labrador, Canada
     (the "CANADIAN QUALIFYING JURISDICTIONS") a preliminary short form
     prospectus relating to the Shares (in the English and French languages, as
     applicable, the "CANADIAN PRELIMINARY PROSPECTUS"). The Company has filed
     the Canadian Preliminary Prospectus with the Principal Canadian Regulator
     and the Canadian Securities Regulatory Authorities pursuant to National
     Policy 43-201 - Mutual Reliance Review System for Prospectuses and Annual
     Information Forms and its related memorandum of understanding, and the
     Principal Canadian Regulator is acting as principal regulator. The Company
     has also filed the Canadian Preliminary Prospectus with the Principal
     Canadian Regulator and the Canadian Securities Regulatory Authorities
     pursuant to National


                                                                               2

     Instrument 44-103 - Post-Receipt Pricing (the "PREP PROCEDURES"). The
     Principal Canadian Regulator has issued a preliminary Mutual Reliance
     Review System Decision Document for the Canadian Preliminary Prospectus.
     The Company has prepared in conformity with the requirements of the United
     States Securities Act of 1933, as amended (the "SECURITIES ACT"), and the
     rules and regulations thereunder, and filed with the United States
     Securities and Exchange Commission (the "COMMISSION") a registration
     statement on Form F-10 (File No. 333-110219) covering the registration of
     the Shares under the Securities Act, including the Canadian Preliminary
     Prospectus (with such deletions therefrom and additions thereto as are
     permitted or required by Form F-10 and the applicable rules and regulations
     (the "RULES AND REGULATIONS") of the Commission) (the "U.S. PRELIMINARY
     PROSPECTUS").


         (b) The Company (A) has prepared and filed (1) with the Principal
     Canadian Regulator and the Canadian Securities Regulatory Authorities, a
     final short form prospectus relating to the Shares (in the English and
     French languages, as applicable, the "CANADIAN FINAL PREP PROSPECTUS")
     which omits the PREP Information (as hereinafter defined) in accordance
     with the PREP Procedures and (2) with the Commission, an amendment to such
     registration statement, including the Canadian Final PREP Prospectus (with
     such deletions therefrom and additions thereto as are permitted or required
     by Form F-10 and the Rules and Regulations), and (B) will prepare and file,
     promptly and, in any event, within one business day after the execution and
     delivery of this Agreement, (1) with the Principal Canadian Regulator and
     the Canadian Securities Regulatory Authorities, in accordance with the PREP
     Procedures, a Canadian Supplemented PREP Prospectus setting forth the PREP
     Information (in the English and French languages, as applicable, the
     "CANADIAN SUPPLEMENTED PREP PROSPECTUS"), and (2) with the Commission, in
     accordance with General Instruction II.L. of Form F-10, the Canadian
     Supplemented PREP Prospectus (with such deletions therefrom and additions
     thereto as are permitted or required by Form F-10 and the Rules and
     Regulations) (the "U.S. SUPPLEMENTED PROSPECTUS"). Copies of the
     registration statement, the amendments thereto and the form of the U.S.
     Supplemented Prospectus have been delivered by the Company to you. Copies
     of the Canadian Preliminary Prospectus and the Canadian Final PREP
     Prospectus and the form of the Canadian Supplemented PREP Prospectus have
     been delivered by the Company to you. The information included in the
     Canadian Supplemented PREP Prospectus that is omitted from the Canadian
     Final PREP Prospectus and which is deemed under the PREP Procedures to be
     incorporated by reference in the Canadian Final PREP Prospectus as of the
     date of the Canadian Supplemented PREP Prospectus is referred to herein as
     the "PREP INFORMATION." Each prospectus relating to the Shares (A) used in
     the United States (1) before the time such registration statement on Form
     F-10 became effective or (2) after such effectiveness and prior to the
     execution and delivery of this Agreement or (B) used in Canada (1) before a
     final Mutual Reliance Review System Decision Document for the Canadian
     Final PREP Prospectus had been received from the Principal Canadian
     Regulator on behalf of itself and the Canadian Securities Regulatory
     Authorities or (2) after such final Mutual Reliance Review System Decision
     Document has been received and prior to the execution and delivery of this
     Agreement, in each case, including the documents incorporated by reference
     therein, that omits the PREP Information, is herein called a "PRELIMINARY
     PROSPECTUS." Such registration statement on Form F-10, including the


                                                                               3


     exhibits thereto and the documents incorporated by reference therein, as
     amended at the time it became effective is herein called the "REGISTRATION
     STATEMENT." The prospectus included in the Registration Statement at the
     time it became effective, including the documents incorporated by reference
     therein, is herein called the "U.S. PROSPECTUS", except that if a U.S.
     Supplemented Prospectus containing the PREP Information is thereafter
     furnished to the Underwriters after the execution of this Agreement
     (whether or not such prospectus is required to be filed pursuant to the
     Rules and Regulations), the term "U.S. PROSPECTUS" shall refer to such U.S.
     Supplemented Prospectus, including the documents incorporated by reference
     therein. The Canadian Final PREP Prospectus for which a final Mutual
     Reliance Review System Decision Document has been received from the
     Principal Canadian Regulator on behalf of itself and the Canadian
     Securities Regulatory Authorities, including the documents incorporated by
     reference therein, is herein referred to as the "CANADIAN PROSPECTUS",
     except that, if, after the execution of this Agreement, a Canadian
     Supplemented PREP Prospectus containing the PREP Information is thereafter
     filed with the Principal Canadian Regulator and the Canadian Securities
     Regulatory Authorities, the term "CANADIAN PROSPECTUS" shall refer to such
     Canadian Supplemented PREP Prospectus, including the documents incorporated
     by reference therein. Any amendment to the Canadian Prospectus, any amended
     or supplemental prospectus or auxiliary material, information, evidence,
     return, report, application, statement or document that may be filed by or
     on behalf of the Company under the securities laws of the Province of
     British Columbia or the Canadian Qualifying Jurisdictions (collectively,
     the "CANADIAN SECURITIES LAWS") prior to the Second Delivery Date (as
     hereinafter defined) or, where such-document is deemed to be incorporated
     by reference into the Canadian Final PREP Prospectus, prior to the expiry
     of the period of distribution of the Shares, is referred to herein
     collectively as the "SUPPLEMENTARY MATERIAL." The Canadian Prospectus and
     the U.S. Prospectus are referred to collectively herein as the
     "PROSPECTUS."


         (c) The Company is qualified to file a prospectus in the form of a
     short form prospectus pursuant to the requirements of National Instrument
     44-101-Short Form Prospectus Distributions. The Company meets the general
     eligibility requirements for use of Form F-10 under the Securities Act. A
     final Mutual Reliance Review System Decision Document has been received
     from the Principal Canadian Regulator on behalf of itself and the Canadian
     Securities Regulatory Authorities in respect of the Canadian Final PREP
     Prospectus and no order suspending the distribution of the Shares has been
     issued by the Principal Canadian Regulator or any of the Canadian
     Securities Regulatory Authorities. The Registration Statement has become
     effective under the Securities Act and no stop order suspending the
     effectiveness of the Registration Statement has been issued under the
     Securities Act and no proceedings for that purpose have been instituted or
     are pending or, to the knowledge of the Company, are contemplated by the
     Commission, and any request on the part of the Commission for additional
     information has been complied with.

         (d) At the time the Registration Statement and any amendments or
     supplements thereto became effective under the Securities Act and at all
     times subsequent thereto up to and including the Second Delivery Date (as
     defined herein): (A) the Canadian Prospectus complied and will comply in
     all material respects with the Canadian


                                                                               4

     Securities Laws; (B) the U.S. Prospectus conformed and will conform to the
     Canadian Prospectus except for such deletions therefrom and additions
     thereto as are permitted or required by Form F-10 and the Rules and
     Regulations; (C) the Registration Statement and any amendments or
     supplements thereto complied and will comply in all material respects with
     the requirements of the Securities Act and the Rules and Regulations; (D)
     neither the Registration Statement nor any amendment or supplement thereto
     contained or will contain an untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading; and (E) each of the Canadian
     Prospectus, any Supplementary Material or any amendment or supplement
     thereto, together with each document incorporated therein by reference,
     constituted and will constitute full, true and plain disclosure of all
     material facts relating to the Company and the Shares, and each of the U.S.
     Prospectus, the Canadian Prospectus and any Supplementary Material or any
     amendment or supplement thereto, together with each document incorporated
     therein by reference, did not and will not contain an untrue statement of a
     material fact or omit to state a material fact necessary in order to make
     the statements therein, in light of the circumstances under which they were
     made, not misleading, except that the representations and warranties
     contained in clauses (D) and (E) above do not apply to statements or
     omissions made in reliance upon and in conformity with information relating
     to any Underwriter furnished in writing to the Company by any Underwriter
     expressly for use in the Registration Statement, the U.S. Prospectus, the
     Canadian Prospectus or any Supplementary Material.

         (e) Each document filed or to be filed with the Principal Canadian
     Regulator and the Canadian Securities Regulatory Authorities and
     incorporated or deemed to be incorporated by reference in the Canadian
     Prospectus complied or will comply when so filed and at a Delivery Date (as
     defined in Section 5 hereof) in all material respects with the Canadian
     Securities Laws and none of such documents contained or will contain at the
     time of its filing any untrue statement of a material fact or omitted or
     will omit at the time of its filing to state a material fact required to be
     stated therein or necessary to make the statements therein, in light of the
     circumstances under which they were or are made, not misleading.

         (f) The documents incorporated or deemed to be incorporated by
     reference in the Registration Statement and the U.S. Prospectus, at the
     time they were or hereafter are filed with the Commission, complied and
     will comply in all material respects with the requirements of the United
     States Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"),
     and the Rules and Regulations, and, when read together with the other
     information in the U.S. Prospectus, at the time the Registration Statement
     became effective, at the time the U.S. Prospectus was issued and at a
     Delivery Date did not and will not contain an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading.

         (g) The Company and each of the Subsidiaries have been duly formed and
     are validly existing and in good standing under the laws of their
     respective jurisdictions of organization, are duly qualified to do business
     and are in good standing as foreign entities in each jurisdiction in which
     their respective ownership or lease of property or the conduct of their
     respective businesses requires such qualification except, with respect to


                                                                               5

     each Subsidiary, where the failure to be so qualified or in good standing
     would not have a material adverse effect, and have all power and authority
     necessary to own or hold their respective properties and to conduct the
     businesses in which they are engaged; and Schedule 3 contains a complete
     list of each subsidiary of the Company that is a "Significant Subsidiary"
     of the Company (as such term is defined in Rule 1-02 of Regulation S-X
     ("RULE 1-02") under the Securities Act of 1933, as amended, and certain
     other subsidiaries of the Company not included in Schedule 3 do not, when
     considered in the aggregate as a single subsidiary, constitute a
     "Significant Subsidiary" (as defined in Rule 1-02).

         (h) The Company has an authorized capitalization as set forth under the
     heading "DESCRIPTION OF SHARE CAPITAL" in the Prospectus, and all of the
     issued shares in the capital of the Company have been duly and validly
     authorized and issued, are fully paid and non-assessable and conform to the
     description thereof contained in the Prospectus; and all of the issued
     shares in the capital or shares of capital stock of each Subsidiary have
     been duly and validly authorized and issued and are fully paid and
     non-assessable and are owned directly or indirectly by the Company, free
     and clear of all liens, encumbrances, equities or claims, except for the
     general security agreement between the Company and Royal Bank, dated as of
     October 7, 1996 (the "ROYAL BANK GENERAL SECURITY AGREEMENT"). All of the
     Company's options, warrants or other rights to purchase or exchange any
     securities for shares of the Company's capital stock have been duly and
     validly authorized and issued, were issued in compliance with federal,
     provincial and state securities laws, and conform to the descriptions
     thereof contained in the Prospectus.

         (i) The Shares to be sold by the Company under the Registration
     Statement and Prospectus have been duly and validly authorized and, when
     issued and delivered against payment therefor as provided herein, will be
     duly and validly issued, fully paid and non-assessable and will conform to
     the description thereof contained in the Prospectus. Upon payment for and
     delivery of such Shares pursuant to this Agreement, the Underwriters will
     acquire good and valid title to such Shares, free and clear of all liens,
     encumbrances, equities, preemptive rights, subscription rights, other
     rights to purchase, voting or transfer restrictions and other claims.

         (j) This Agreement has been duly authorized, executed and delivered by
     the Company.

         (k) The execution, delivery and performance of this Agreement by the
     Company and the consummation of the transactions contemplated hereby will
     not conflict with or result in a breach or violation of (i) any of the
     terms or provisions of, or constitute a default under, any indenture,
     mortgage, deed of trust, loan agreement or other agreement or instrument to
     which the Company or any of the Subsidiaries is a party or by which the
     Company or any of the Subsidiaries is bound or to which any of the
     properties or assets of the Company or any of the Subsidiaries is subject,
     or (ii) the charter, by-laws or other organizational documents of the
     Company or any of the Subsidiaries or (iii) any statute or any order, rule
     or regulation of any court or governmental agency or body having
     jurisdiction over the Company or any of the Subsidiaries or any of their
     properties or


                                                                               6


     assets, in the case of (i) the effect of which would have a material
     adverse effect or impair the ability of the Company to consummate the
     transactions contemplated in the Registration Statement and Prospectus; and
     except for the registration of the Shares under the Securities Act and such
     consents, approvals, authorizations, registrations or qualifications as may
     be required under the Exchange Act, the Canadian Securities Laws and
     applicable state or foreign securities laws in connection with the purchase
     and distribution of the Shares by the Underwriters, no consent, approval,
     authorization or order of, or filing or registration with, any such court
     or governmental agency or body is required for the execution, delivery and
     performance of this Agreement by the Company and the consummation of the
     transactions contemplated hereby.

         (l) Except as required under the Amended and Restated Registration
     Rights Agreement dated September 30, 1998 (the "Registration Rights
     Agreement"), which rights have been satisfied or waived in connection with
     the sale of the Shares, there are no contracts, agreements or
     understandings between the Company and any person granting such person the
     right (other than rights which have been waived or satisfied) to require
     the Company to file a registration statement under the Securities Act or a
     prospectus under the Canadian Securities Laws with respect to any
     securities of the Company owned or to be owned by such person or to require
     the Company to include such securities in the securities registered
     pursuant to the Registration Statement or qualified for distribution
     pursuant to the Canadian Prospectus or in any securities being registered
     pursuant to any other registration statement filed by the Company under the
     Securities Act or qualified for distribution pursuant to any other
     prospectus filed by the Company under the Canadian Securities Laws.

         (m) Except as described in the Prospectus, the Company has not sold or
     issued any common shares during the six-month period preceding the date of
     the Prospectus, including any sales pursuant to Rule 144A under, or
     Regulations D or S of, the Securities Act, other than shares issued
     pursuant to employee benefit plans, qualified share option plans or other
     employee compensation plans or pursuant to outstanding options, rights or
     warrants.

         (n) (i) Neither the Company nor any of the Subsidiaries has sustained,
     since the date of the latest audited financial statements incorporated by
     reference in the Prospectus, any material 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
     Prospectus; and, (ii) since such date, there has not been any material
     change in the share capital or long-term debt of the Company or any of the
     Subsidiaries or any material adverse change, or any development that in the
     Company's reasonable judgment as of this date is more likely than not to
     involve a prospective material adverse change, in or affecting the general
     affairs, management, financial position, shareholders' equity or results of
     operations of the Company and the Subsidiaries, otherwise than as set forth
     or contemplated in the Prospectus.

         (o) The financial statements (including the related notes and
     supporting schedules and any pro forma financial statements) incorporated
     by reference in the


                                                                               7


     Prospectus present fairly the financial condition and results of operations
     of the entities purported to be shown thereby, at the dates and for the
     periods indicated, and have been prepared in conformity with, in the case
     of the Registration Statement and the U.S. Prospectus, United States
     generally accepted accounting principles and, in the case of the Canadian
     Prospectus, Canadian generally accepted accounting principles, in each case
     applied on a consistent basis throughout the periods involved, except that
     all historical financial statements of AirPrime, Inc. (now called Sierra
     Wireless America, Inc.) were prepared solely in conformity with United
     States generally accepted accounting principles, and except as otherwise
     stated therein.

         (p) (i) KPMG LLP, who have certified certain financial statements of
     the Company, whose report is incorporated by reference in the Prospectus
     and who have delivered the initial letter referred to in Section 9(h)(i)
     hereof, are independent public accountants as required by the Securities
     Act and the Rules and Regulations and independent chartered accountants as
     required by Canadian Securities Laws; and, (ii) Deloitte & Touche LLP, who
     have certified certain financial statements of AirPrime, Inc., whose report
     is incorporated by reference in the Prospectus, and who have delivered the
     letter referred to in Section 9(h)(ii) hereof, were, during the periods
     covered by the report, independent public accountants as required by the
     Securities Act and the Rules and Regulations. Except as described in the
     Prospectus and as pre-approved in accordance with the requirements set
     forth in Section 10A of the Exchange Act, neither KPMG LLP nor Deloitte &
     Touche LLP has engaged in any "prohibited activities" (as defined in
     Section 10A of the Exchange Act) on behalf of the Company or its
     Subsidiaries.

         (q) The Company and each of the Subsidiaries own no real property and
     have good and marketable title to all personal property reflected as owned
     by them, in each case free and clear of all liens, encumbrances and defects
     (except under the Royal Bank General Security Agreement) except such as are
     described in the Prospectus or such as do not materially affect the value
     of such personal property and do not materially interfere with the use made
     and proposed to be made of such personal property by the Company and the
     Subsidiaries; and all real property and buildings held under lease by the
     Company and the Subsidiaries are held by them under valid, subsisting and
     enforceable leases, with such exceptions as are not material and do not

         proceedings have been taken and all necessary authorizations,
         approvals, permits, consents and orders have been obtained under the
         Canadian Securities Laws to permit the Shares to be issued, offered,
         sold and delivered in the Canadian Qualifying Jurisdictions by or
         through persons registered under such laws; and no other consent,
         approval, authorization, license, order, registration, qualification or
         decree of or with any government, governmental instrumentality,
         authority or agency or court of Canada or of any Canadian Qualifying
         Jurisdiction is required to be obtained by the Company or the Selling
         Shareholders for such issuance, offering, sale or delivery of the
         Shares or the consummation by the Company and the Selling Shareholders
         of the transactions contemplated by this Agreement, except such as have
         been obtained.

               (xvi) 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, provided that such choice of law
         is bona fide (in the sense that it was not made with a view to avoiding
         the consequences of the laws of any other jurisdiction) and provided
         that such choice of law is not contrary to public policy as that term
         is applied by a British Columbia Court ("Public Policy"). In such
         counsel's opinion, there is no reason under the laws of the Province of
         British Columbia or the federal laws of Canada applicable therein for a
         British Columbia Court to not give effect to the choice of New York law
         to govern this Agreement, subject to the aforementioned provisos.

               (xvii) 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 DWT Corp. as its agent to receive service of process in
         the United States of America under this Agreement and to provisions in
         this Agreement whereby the Company submits to the non-exclusive
         jurisdiction of a New York Court.

               (xviii) If this Agreement is 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 clause (xvi) above, recognize the
         choice of New York law and, upon appropriate evidence as to such law
         being adduced, apply such law, provided that none of the provisions of
         this Agreement, or of applicable New York law, are contrary to Public
         Policy, provided, however, that, in matters of procedure, the laws of
         the Province of British Columbia will be applied, and 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
         proper forum to hear such an action, or if concurrent proceedings are
         being brought elsewhere.


                                                                              24


               (xix) 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 against the Company, 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 Company, as recognized by a British
         Columbia Court (and submission by the Company in this Agreement to the
         jurisdiction of the New York Court will be deemed sufficient for such
         purpose); (B) 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); (C) the enforcement of such judgment in British Columbia
         does not constitute, directly or indirectly, the enforcement of foreign
         revenue, expropriatory or penal laws; (D) in an action to enforce a
         default judgment, the judgment does not contain a manifest error on its
         face; (E) the enforcement of such judgment in the Province of British
         Columbia does not result in giving foreign laws extraterritorial
         effect; and (F) the action to enforce such judgment is commenced in
         compliance with the Limitations Act (British Columbia), except that a
         British Columbia Court may stay an action to enforce a foreign judgment
         if an appeal is pending or the time for appeal has not expired,
         provided that under the Currency Act (Canada), a British Columbia Court
         may only give judgment in Canadian dollars.

               (xx) All laws of the Province of Quebec relating to the use of
         the French language will have been complied with in connection with the
         sale of the Shares to purchasers in the Province of Quebec provided
         that such purchasers receive copies of the Canadian Prospectus in the
         French language alone, in the English and French languages
         simultaneously or, in the case of purchasers having specifically so
         requested in writing, in the English language alone and that such
         purchasers receive forms of order and confirmation drawn solely in the
         French language or in a bilingual format (on the assumption that no
         documents other than the Canadian Prospectus and the forms of order and
         confirmation constitute the contract for purchase of the Shares).

               (xxi) Neither the Company nor any subsidiary is an "investment
         company" as defined in the Investment Company Act

               (xxii) This Agreement has been duly authorized, executed and
         delivered by Sierra Wireless Data, Inc. and Sierra Wireless America,
         Inc.

               In rendering such opinion, such counsel, in the case of Blake,
         Cassels Graydon LLP, may (i) state that its opinion is limited to
         matters governed by the laws of British Columbia, Alberta, Ontario and
         Quebec and the federal laws of Canada having application there; and
         (ii) rely (to the extent such counsel deems proper and specifies in its
         opinion), as to matters involving the application of the laws of the
         other Canadian Qualifying Jurisdictions, the State of Delaware,


                                                                              25


          England and Wales, and Hong Kong and upon the opinion of other counsel
          of good standing, provided that such other counsel is satisfactory to
          counsel for the Underwriters and furnishes a copy of its opinion to
          the Underwriters and, in the case of Davis Wright Tremaine LLP, may
          state that its opinion is limited to matters governed by the federal
          laws of the United States of America and the laws of the State of
          Delaware. Such counsel shall also have furnished to the Underwriters
          a written statement, addressed to the Underwriters and dated such
          Delivery Date, in form and substance satisfactory to the Underwriters,
          to the effect that (x) such counsel has acted as counsel to the
          Company on a regular basis (except that, with respect to intellectual
          property matters, the Company is represented by other outside
          counsel), and has acted as counsel to the Company in connection with
          previous financing transactions and has acted as counsel to the
          Company in connection with the preparation of the Registration
          Statement and the Prospectus, and (y) based on the foregoing, no facts
          have come to the attention of such counsel which lead it to believe
          that the Registration Statement, as of the Effective Date, contained
          any untrue statement of a material fact or omitted to state any
          material fact required to be stated therein or necessary in order to
          make the statements therein not misleading, or that the Prospectus
          contains any untrue statement of a material fact or omits to state a
          material fact required to be stated therein or necessary in order to
          make the statements therein, in light of the circumstances under which
          they were made, not misleading. The foregoing opinion and statement
          may be qualified by a statement to the effect that such counsel does
          not assume any responsibility for the accuracy, completeness or
          fairness of the statements contained in the Registration Statement or
          the Prospectus including the financial statements incorporated by
          reference therein except for the statements made in the U.S.
          Prospectus under the captions "Description of Share Capital," and
          "Certain Tax Considerations for U.S. Holders" and in the Canadian
          Prospectus under the caption "Eligibility for Investment" and
          "Purchasers Statutory Rights," insofar as such statements relate to
          the Shares and concern legal matters.

         (e) Thelen Reed & Priest shall have furnished to the Underwriters their
     written opinion, as patent counsel to the Company, addressed to the
     Underwriters and dated such Delivery Date, in form and substance reasonably
     satisfactory to the Underwriters and their counsel, to the effect that:

               (i) To the best of its knowledge, the statements contained in the
         Prospectus, insofar as they constitute facts pertaining to its
         representation and involve matters of US law, are accurate statements
         or summaries of the matters therein set forth.

               (ii) To the best of its knowledge, the issued patents described
         in [Exhibits] hereto were validly and properly issued.

               (iii) To the best of its knowledge, except as described in the
         Prospectus and except for ex parte prosecution of patent applications
         and potential interferences or re-examination proceedings initiated by
         the Company between patents of the Company and


                                                                              26


          patents of others, there are no legal or governmental proceedings,
          pending or threatened, relating to the patents or patent applications
          of the Company.

               (iv) To the best of its knowledge, except as described in the
         Prospectus and except for potential interferences or re-examination
         proceedings initiated by the Company between patents of the Company
         and patents of others, there are no legal or governmental proceedings,
         pending or threatened, against the Company with respect to the patents
         or patent applications of others.

               (v) To the best of its knowledge, it and the Company have
         properly filed and have prosecuted in a timely manner, or are so
         prosecuting, each of the Company's pending patent applications and
         granted patents.

               (vi) In prosecution of the United States patents and patent
         applications listed in [Exhibits], it has complied and is continuing to
         comply and, to the best of its knowledge, the Company has complied and
         is continuing to comply, in each case on an ongoing basis with the
         requirements of the United States Patent and Trademark Office as set
         forth in 37 C.F.R. Section 1.56.

               (vii) To the best of its knowledge, the Company has clear title
         to or has rights in the issued patents and pending patent applications
         described in [Exhibit] hereto.

               (viii) None of the issued patents described in [Exhibit] hereto
         has been revoked.

               (ix) To its knowledge, based upon the information provided to
         it by the Company, the Company is not infringing or otherwise violating
         any patents of others.

         (f) The respective counsel for each of the Selling Shareholders listed
     in Schedule 2 (which counsel may also be counsel to the Company) shall each
     have furnished to the Underwriters its written opinion, as counsel to the
     Selling Shareholder for whom it is acting as counsel, addressed to the
     Underwriters and dated the First Delivery Date, in form and substance
     reasonably satisfactory to the Underwriters and their counsel, to the
     effect that:

               (i) Based solely (A) on its review of the certificate(s)
         representing the Shares to be delivered by the Selling Shareholder and
         (B) search results under the Personal Property Security Act (Ontario)
         and Personal Property Security Act (British Columbia) and assuming (x)
         that the Shares were validly issued by the Company to the Selling
         Shareholder; and (y) the Underwriters do not have or are not deemed to
         have any knowledge or any adverse claim (as such term is referred to in
         the Canada Business Corporations Act) as it relates to the Shares:

               (1) immediately prior to the First Delivery Date, such Selling
         Shareholder is the registered owner of the Shares to be sold by such
         Selling Shareholder under this Agreement, and such Shares are free from
         any security interest perfected by


                                                                              27


          registration under the Personal Property Security Act (Ontario) and
          Personal Property Security Act (British Columbia);

               (2) each of the several Underwriters has acquired such Shares,
         free from any adverse claim in accordance with Section 60(2) of the
         Canada Business Corporations Act.

         In rendering such opinion, such counsel may (i) state that its opinion
     is limited to matters governed by the laws of British Columbia and the
     federal laws of Canada and (ii) in rendering the opinion in Section 9(f)(i)
     above, rely upon a certificate of such Selling Shareholder in respect of
     matters of fact as to ownership of and liens, encumbrances, equities or
     claims on the shares of Shares sold by such Selling Shareholder, provided
     that such counsel shall furnish copies thereof to the Underwriters.


         (g) The Underwriters shall have received from Simpson Thacher &
     Bartlett LLP, U.S. counsel for the Underwriters, such opinion or opinions,

     reasonably require, and the Company shall have furnished to such counsel
     such documents as they reasonably request for the purpose of enabling them

                                                                              28


         (i) With respect to the letter of KPMG LLP referred to in the preceding
     paragraph and delivered to the Underwriters concurrently with the execution
     of this Agreement (the "INITIAL LETTER"), the Company shall have furnished
     to the Underwriters a letter (the "BRING-DOWN LETTER") of such accountants,

         the Prospectus and, in their opinion (A) the Registration Statement and
         the Prospectus, as of the Effective Date, did not include any untrue
         statement of a material fact and did not omit to state any material
         fact required to be stated therein or necessary to make the statements
         therein not misleading, and (B) since the Effective Date of the
         Registration Statement, no event has occurred which should have been
         set forth in a supplement or amendment to the Registration Statement or
         the Prospectus.

         (k) Each Selling Shareholder shall have furnished to the Underwriters
     on the First Delivery Date a certificate, dated the First Delivery Date,
     signed by, or on behalf of, such Selling Shareholder stating that the
     representations, warranties and agreements of such Selling Shareholder
     contained herein are true and correct as of the First Delivery Date and

     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
     Prospectus or (ii) since such date there shall not have been any material
     change in the share capital, long-term debt or intellectual property of the
     Company or any of the


                                                                              29


     Subsidiaries or any material adverse change, or any development involving a
     prospective material adverse change, in or affecting the general affairs,
     management, financial position, shareholders' equity or results of
     operations of the Company and the Subsidiaries, 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 Shares being
     delivered on such Delivery Date on the terms and in the manner contemplated
     in the Prospectus.

         (m) Subsequent to the execution and delivery of this Agreement there
     shall not have occurred any of the following: (i) trading in securities
     generally on the New York Stock Exchange, the American Stock Exchange or
     the TSX or in the over-the-counter market, or trading in any securities of
     the Company on any exchange or in the over-the-counter market, shall have

     major hostilities, there shall have been an escalation in major hostilities
     involving the United States or Canada or there shall have been a
     declaration of a national emergency or war by the United States or Canada
     or (iv) there shall have occurred such a material adverse change in general
     economic, political or financial conditions (or the effect of international
     conditions on the financial markets in the United States shall be such) as
     to make it, in the reasonable judgment of a majority in interest of the
     several Underwriters, impracticable or inadvisable to proceed with the
     public offering or delivery of the Shares being delivered on such Delivery
     Date on the terms and in the manner contemplated in the Prospectus.

         (n) Nasdaq and the TSX shall have conditionally approved the Shares to
     be issued and sold by the Company hereunder for listing, subject only to
     official notice of issuance and the filing of all required documentation.

         All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriters.

         10. INDEMNIFICATION AND CONTRIBUTION

         (a) The Company and the Subsidiaries, jointly and severally, shall
     indemnify and hold harmless each Underwriter (including any Underwriter in
     its role as qualified independent underwriter pursuant to the rules of the
     National Association of Securities Dealers, Inc.), its officers and
     employees and each person, if any, who controls any Underwriter within the
     meaning of the Securities Act, from and against any loss, claim, damage or
     liability, joint or several, or any action in respect thereof (including,
     but not limited to, any loss, claim, damage, liability or action relating
     to purchases and sales of Shares), to which that Underwriter, officer,
     employee or controlling person may become subject, under the Securities
     Act, the Canadian Securities Laws or otherwise, insofar as such loss,
     claim, damage, liability or action arises out of, or is based upon, (i) any
     untrue


                                       30


     statement or alleged untrue statement of a material fact contained (A) in
     any Preliminary Prospectus, the Registration Statement or the Prospectus,
     or in any amendment or supplement thereto or (B) in any materials or
     information provided to investors by, or on behalf of, the Company in
     connection with the marketing of the offering of the Shares, including any
     roadshow or investor presentation made to investors by the Company (whether
     in person or electronically) ("ROADSHOW MATERIALS"), (ii) the omission or
     alleged omission to state in any Preliminary Prospectus, the Registration
     Statement or the Prospectus, or in any amendment or supplement thereto, or
     in any Roadshow Materials that has been reviewed by the Company any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading or (iii) any act or failure to act or any
     alleged act or failure to act by any Underwriter in connection with, or
     relating in any manner to, the Shares or the offering contemplated hereby,
     and which is included as part of or referred to in any loss, claim, damage,
     liability or action arising out of or based upon matters covered by clause
     (i) or (ii) above (PROVIDED that the Company and the Subsidiaries shall not
     be liable in the case of any matter covered by this clause (iii) to the
     extent that it is determined in a final judgment by a court of competent
     jurisdiction that such loss, claim, damage, liability or action resulted
     directly from any such act or failure to act undertaken or omitted to be
     taken by such Underwriter through its gross negligence, contravention of
     law or willful misconduct), and shall reimburse each Underwriter and each
     such officer, employee and controlling person promptly upon demand for any
     legal or other expenses reasonably incurred by that Underwriter, officer,
     employee or controlling person in connection with investigating or
     defending or preparing to defend against any such loss, claim, damage,
     liability or action as such expenses are incurred; PROVIDED, HOWEVER, that
     the Company and the Subsidiaries shall not be liable in any such case to
     the extent that any such loss, claim, damage, liability or action arises
     out of, or is based upon, any untrue statement or alleged untrue statement
     or omission or alleged omission made in any Preliminary Prospectus, the
     Registration Statement or the Prospectus, or in any such amendment or
     supplement, in reliance upon and in conformity with the written information
     concerning such Underwriter furnished to the Company by any Underwriter
     specifically for inclusion therein, which information consists solely of
     the information specified in Section 10(f), PROVIDED, FURTHER, that the
     indemnity agreement provided in this Section 10(a) with respect to any
     Preliminary Prospectus shall not inure to the benefit of any Underwriter
     from whom the person asserting any loss, claim, charge, liability or
     litigation based upon any untrue statement or alleged untrue statement of
     material fact or omission or alleged omission to state therein a material
     fact purchased Shares, if a copy of the Prospectus in which such untrue
     statement or alleged untrue statement or omission or alleged omission was
     corrected was not sent or given within the time required by the Securities
     Act and the Rules and Regulations or the Canadian Securities Laws, as
     applicable, unless such failure is the result of noncompliance by the
     Company with Section 6(f) hereof. The foregoing indemnity agreement is in
     addition to any liability which the Company or any Subsidiary may otherwise
     have to any Underwriter or to any officer, employee or controlling person
     of that Underwriter.

         (b) The Selling Shareholders, severally and not jointly, shall
     indemnify and hold harmless each Underwriter, its officers and employees,
     and each person, if any, who controls any Underwriter within the meaning of
     the Securities Act, from and against any


                                                                              31


     loss, claim, damage or liability, joint or several, or any action in
     respect thereof (including, but not limited to, any loss, claim, damage,
     liability or action relating to purchases and sales of Shares), to which
     that Underwriter, officer, employee or controlling person may become
     subject, under the Securities Act, the Canadian Securities Laws or
     otherwise, insofar as such loss, claim, damage, liability or action arises
     out of, or is based upon, (i) any breach of the Selling Shareholder's
     representations set forth in Section 2 of this Agreement or (ii) any untrue
     statement or alleged untrue statement of a material fact contained in any
     Preliminary Prospectus, the Registration Statement or the Prospectus, or in
     any amendment or supplement thereto, that was provided by such Selling
     Shareholder to the Company for inclusion therein; PROVIDED, FURTHER, that
     the indemnity agreement provided in this Section 10(a) with respect to any
     Preliminary Prospectus shall not inure to the benefit of any Underwriter
     from whom the person asserting any loss, claim, charge, liability or
     litigation based upon any untrue statement or alleged untrue statement of
     material fact or omission or alleged omission to state therein a material
     fact purchased Shares, if a copy of the Prospectus in which such untrue
     statement or alleged untrue statement or omission or alleged omission was
     corrected was not sent or given within the time required by the Securities
     Act and the Rules and Regulations or the Canadian Securities Laws, as
     applicable, unless such failure is the result of noncompliance by the
     Company with Section 6(f) hereof. The foregoing indemnity agreement is in
     addition to any liability which the Selling Shareholders may otherwise have
     to any Underwriter or to any officer, employee or controlling person of
     that Underwriter. Notwithstanding the provisions of this Section 10(b), in
     no event shall any Selling Shareholder be required to make any
     indemnification payment or liability obligation to the extent such amount
     is in excess of the net proceeds received by such Selling Shareholder in
     the offering of the Shares by such Selling Shareholder.

         (c) Each Underwriter, severally and not jointly, shall indemnify and
     hold harmless the Company, its officers and employees, each of its
     directors, and each person, if any, who controls the Company within the
     meaning of the Securities Act, from and against any loss, claim, damage or
     liability, joint or several, or any action in respect thereof, to which the
     Company or any such director, officer or controlling person may become
     subject, under the Securities Act, the Canadian Securities Laws, or
     otherwise, insofar as such loss, claim, damage, liability or action arises
     out of, or is based upon, (i) any untrue statement or alleged untrue
     statement of a material fact contained in any Preliminary Prospectus, the
     Registration Statement or the Prospectus or in any amendment or supplement
     thereto or (ii) the omission or alleged omission to state in any
     Preliminary Prospectus, the Registration Statement or the Prospectus, or in
     any amendment or supplement thereto, any material fact required to be
     stated therein or necessary to make the statements therein not misleading,
     but in each case only to the extent that the untrue statement or alleged
     untrue statement or omission or alleged omission was made in reliance upon
     and in conformity with written information concerning such Underwriter
     furnished to the Company through the Underwriters by or on behalf of that
     Underwriter specifically for inclusion therein and described in Section
     10(f), and shall reimburse the Company and any such director, officer or
     controlling person for any legal or other expenses reasonably incurred by
     the Company or any such director, officer or controlling person in
     connection with investigating or defending or preparing to defend against
     any such loss, claim, damage, liability or action as such


                                                                              32


     expenses are incurred. The foregoing indemnity agreement is in addition to
     any liability which any Underwriter may otherwise have to the Company or
     any such director, officer, employee or controlling person.

         (d) Promptly after receipt by an indemnified party under this Section
     10 of notice of any claim or the commencement of any action, the
     indemnified party shall, if a claim in respect thereof is to be made
     against the indemnifying party under this Section 10, notify the
     indemnifying party in writing of the claim or the commencement of that
     action; PROVIDED, HOWEVER, that the failure to notify the indemnifying
     party shall not relieve it from any liability which it may have under this
     Section 10 except to the extent it has been materially prejudiced by such
     failure and, PROVIDED FURTHER, that the failure to notify the indemnifying
     party shall not relieve it from any liability which it may have to an
     indemnified party otherwise than under this Section 10. If any such claim
     or action shall be brought against an indemnified party, and it shall
     notify the indemnifying party thereof, the indemnifying party shall be
     entitled to participate therein and, to the extent that it wishes, jointly
     with any other similarly notified indemnifying party, to assume the defense
     thereof with counsel reasonably satisfactory to the indemnified party.
     After notice from the indemnifying party to the indemnified party of its
     election to assume the defense of such claim or action, the indemnifying
     party shall not be liable to the indemnified party under this Section 10
     for any legal or other expenses subsequently incurred by the indemnified
     party in connection with the defense thereof other than reasonable costs of
     investigation; PROVIDED, HOWEVER, that the Underwriters shall have the
     right to employ counsel to represent jointly the Underwriters and their
     respective officers, employees and controlling persons who may be subject
     to liability arising out of any claim in respect of which indemnity may be
     sought by the Underwriters against the Company, any Subsidiary or any
     Selling Shareholder under this Section 10 if, in the reasonable judgment of
     the Underwriters, it is advisable for the Underwriters to be represented by
     separate counsel, and in that event the fees and expenses of such separate
     counsel shall be paid by the Company, the Subsidiaries or the Selling
     Shareholders. Any indemnified party shall have the right to employ separate
     counsel in any such action and to participate in the defense thereof but
     the fees and expenses of such counsel shall be at the expense of such
     indemnified party unless (i) the employment thereof has been specifically
     authorized by the indemnifying party in writing, (ii) such indemnified
     party shall have been advised by such counsel that there may be one or more
     legal defenses available to it which are different from or additional to
     those available to the indemnifying party and in the reasonable judgment of
     such counsel it is advisable for such indemnified party to employ separate
     counsel or (iii) the indemnifying party has failed to assume the defense of
     such action and employ counsel reasonably satisfactory to the indemnified
     party, in which case, if such indemnified party notifies the indemnifying
     party in writing that it elects to employ separate counsel at the expense
     of the indemnifying party, the indemnifying party shall not have the right
     to assume the defense of such action on behalf of such indemnified party
     (but for clarification, will continue to have the right to employ counsel
     to assume the defense for such action, on its own behalf), it being
     understood, however, that the indemnifying party shall not, in connection
     with any one such action or separate but substantially similar or related
     actions in the same jurisdiction arising out of the same general
     allegations or circumstances, be liable for the reasonable fees and
     expenses of more than one separate firm of attorneys at any


                                                                              33


     time for all such indemnified parties, which firm shall be designated in
     writing by the Underwriters, if the indemnified parties under this Section
     10 consist of any Underwriter or any of their respective officers,
     employees or controlling persons, or by the Company, if the indemnified
     parties under this Section 10 consist of the Company or any of the
     Company's directors, officers, employees or controlling persons or any
     Selling Shareholder. No indemnifying party shall (i) without the prior
     written consent of the indemnified parties (which consent shall not be
     unreasonably withheld), settle or compromise or consent to the entry of any
     judgment with respect to any pending or threatened claim, action, suit or
     proceeding in respect of which indemnification or contribution may be
     sought hereunder (whether or not the indemnified parties are actual or
     potential parties to such claim or action) unless such settlement,
     compromise or consent includes an unconditional release of each indemnified
     party from all liability arising out of such claim, action, suit or
     proceeding, or (ii) be liable for any settlement of any such action
     effected without its written consent (which consent shall not be
     unreasonably withheld), but if settled with the written consent of the
     indemnifying party or if there be a final judgment of the plaintiff in any
     such action, the indemnifying party agrees to indemnify and hold harmless
     any indemnified party from and against any loss or liability by reason of
     such settlement or judgment.

         (e) If the indemnification provided for in this Section 10 shall for
     any reason be unavailable to or insufficient to hold harmless an
     indemnified party under Section 10(a) 10(b) or 10(c) in respect of any
     loss, claim, damage or liability, or any action in respect thereof,
     referred to therein, then each indemnifying party shall, in lieu of
     indemnifying such indemnified party, contribute to the amount paid or
     payable by such indemnified party as a result of such loss, claim, damage
     or liability, or action in respect thereof, (i) in such proportion as shall
     be appropriate to reflect the relative benefits received by the Company,
     the Subsidiaries and the Selling Shareholders on the one hand and the
     Underwriters on the other from the offering of the Shares or (ii) if the
     allocation provided by clause (i) above is not permitted by applicable law,
     in such proportion as is appropriate to reflect not only the relative
     benefits referred to in clause (i) above but also the relative fault of the
     Company, the Subsidiaries, and the Selling Shareholders on the one hand and
     the Underwriters on the other with respect to the statements or omissions
     which resulted in such loss, claim, damage or liability, or action in
     respect thereof, as well as any other relevant equitable considerations.
     The relative benefits received by the Company, the Subsidiaries, and the
     Selling Shareholders on the one hand and the Underwriters on the other with
     respect to such offering shall be deemed to be in the same proportion as
     the total net proceeds from the offering of the Shares purchased under this
     Agreement (before deducting expenses) received by the Company, the
     Subsidiaries, and the Selling Shareholders, on the one hand, and the total
     underwriting discounts and commissions received by the Underwriters with
     respect to the Shares purchased under this Agreement, on the other hand,
     bear to the total gross proceeds from the offering of the Shares under this
     Agreement, in each case as set forth in the table on the cover page of the
     Prospectus. The relative fault shall be determined by reference to whether
     the untrue or alleged untrue statement of a material fact or omission or
     alleged omission to state a material fact relates to information supplied
     by the Company, the Subsidiaries, the Selling Shareholders or the
     Underwriters, the intent of the parties and their relative knowledge,
     access to information and opportunity to correct or prevent such statement
     or


                                                                              34


     omission. For purposes of the preceding two sentences, the net proceeds
     deemed to be received by the Company shall be deemed to be also for the
     benefit of the Subsidiaries and information supplied by the Company shall
     also be deemed to have been supplied by the Subsidiaries. The Company, the
     Subsidiaries, the Selling Shareholders and the Underwriters agree that it
     would not be just and equitable if contributions pursuant to this Section
     10(e) were to be 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 into account the equitable
     considerations referred to herein. The amount paid or payable by an
     indemnified party as a result of the loss, claim, damage or liability, or
     action in respect thereof, referred to above in this Section 10(e) shall be
     deemed to include, for purposes of this Section 10(e), 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 Section 10(e), no Underwriter shall be required to
     contribute any amount in excess of the amount by which the total price at
     which the Shares underwritten by it and distributed to the public was
     offered to the public exceeds the amount of any damages which such
     Underwriter has otherwise paid or become liable to pay by reason of any
     untrue or alleged untrue statement or omission or alleged omission, and no
     Selling Shareholder shall be required to contribute any amount in excess of
     the net proceeds received by such Selling Shareholder in the offering of
     the Shares by such Selling Shareholder. No person guilty of fraudulent
     misrepresentation (within the meaning of Section 10(f) of the Securities
     Act) shall be entitled to contribution from any person who was not guilty
     of such fraudulent misrepresentation. The Underwriters' obligations to
     contribute as provided in this Section 10(e) are several in proportion to
     their respective underwriting obligations and not joint.

         (f) The Underwriters severally confirm and the Company acknowledges
     that the statements with respect to the public offering of the Shares by
     the Underwriters set forth on the cover page of, the legend concerning
     over-allotments on the inside front cover page of and the concession and
     reallowance figures appearing under the caption "Underwriting" in, the
     Prospectus are correct and constitute the only information concerning such
     Underwriters furnished in writing to the Company by or on behalf of the
     Underwriters specifically for inclusion in the Registration Statement and
     the Prospectus.

         11. [INTENTIONALLY OMITTED.]

         12. DEFAULTING UNDERWRITERS

         (a) If, on either Delivery Date, any Underwriter defaults in the
     performance of its obligations under this Agreement, the non-defaulting
     Underwriter shall be obligated to purchase the Shares which the defaulting
     Underwriter agreed but failed to purchase on such Delivery Date provided,
     however, that the non-defaulting Underwriter shall not be obligated to
     purchase any of the Shares on such Delivery Date if the total number of
     Shares which the defaulting Underwriter agreed but failed to purchase on
     such date exceeds 9.09% of the total number of Shares to be purchased on
     such Delivery Date, and the non-defaulting Underwriter shall not be
     obligated to purchase more than 110% of the number of Shares which it
     agreed to purchase on such Delivery Date pursuant to the


                                       35

     terms of Section 3. If the foregoing maximums are exceeded, the
     non-defaulting Underwriter shall have the right, but shall not be
     obligated, to purchase all the Shares to be purchased on such Delivery
     Date. If the non-defaulting Underwriter does not elect to purchase the
     Shares which the defaulting Underwriter agreed but failed to purchase on
     such Delivery Date, this Agreement (or, with respect to the Second Delivery
     Date, the obligation of the Underwriters to purchase, and of the Company to
     sell, the Option Shares) shall terminate without liability on the part of
     any non-defaulting Underwriter or the Company or the Selling Shareholders,
     except that the Company will continue to be liable for the payment of
     expenses to the extent set forth in Sections 8 and 14. As used in this
     Agreement, the term "Underwriter" includes, for all purposes of this
     Agreement unless the context requires otherwise, any party not listed in
     Schedule 1 hereto who, pursuant to this Section 12, purchases Firm Shares
     which a defaulting Underwriter agreed but failed to purchase.

         (b) Nothing contained herein shall relieve a defaulting Underwriter of
     any liability it may have to the Company and the Selling Shareholders for
     damages caused by its default. If other underwriters are obligated or agree
     to purchase the Shares of a defaulting or withdrawing Underwriter, either
     the Underwriters or the Company may postpone the Delivery Date for up to
     seven full business days in order to effect any changes that in the opinion
     of counsel for the Company or counsel for the Underwriters may be necessary
     in the Registration Statement, the Prospectus or in any other document or
     arrangement.

         13. TERMINATION. The obligations of the Underwriters hereunder may be
terminated by the Underwriters by notice given to and received by the Company
and the Selling Shareholders prior to delivery of and payment for the Firm
Shares if, prior to that time, any of the events described in Sections 9(k) or
9(l), shall have occurred or if the Underwriters shall decline to purchase the
Shares for any reason permitted under this Agreement.

         14. REIMBURSEMENT OF UNDERWRITERS' EXPENSES. If (a) the Company or any
Selling Shareholder shall fail to tender the Shares for delivery to the
Underwriters for any reason permitted under this Agreement, or (b) the
Underwriters shall decline to purchase the Shares for any reason permitted under
this Agreement (including the termination of this Agreement pursuant to Section
13), the Company shall reimburse the Underwriters for the reasonable
out-of-pocket expenses (including fees and expenses of counsel) incurred by them
in connection with this Agreement and the proposed purchase of the Shares, and
upon demand the Company shall pay the full amount thereof to the Underwriters.
If this Agreement is terminated pursuant to Section 12 by reason of the default
of one of the Underwriters, neither the Company nor any Selling Shareholder
shall be obligated to reimburse any defaulting Underwriter on account of those
expenses.

         15. NOTICES, ETC. All statements, requests, notices and agreements
hereunder shall be in writing, and:

         (a) if to the Underwriters, shall be delivered or sent by mail, telex

inure to the benefit of and be binding upon the Underwriters, the Company, the
Selling Shareholders and their respective personal representatives (if
applicable) and successors. This Agreement and the terms and provisions hereof
are for the sole benefit of only those persons, except that (A) the
representations, warranties, indemnities and agreements of the Company and the
Selling Shareholders contained in this Agreement shall also be deemed to be for
the benefit of the officers and employees of each Underwriter and the person or

directors of the Company and the Selling Shareholders, officers of the Company
who have signed the Registration Statement, officers of the Selling Shareholder
and any person controlling the Company or the Selling Shareholders within the
meaning of Section 15 of the Securities Act. Nothing in this Agreement is
intended or shall be construed to give any person, other than the persons
referred to in this Section 16, any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision contained herein.

         17. SURVIVAL. The respective indemnities, representations, warranties
and agreements of the Company, the Subsidiaries, the Selling Shareholders and
the Underwriters contained in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall survive the delivery of and
payment for the Shares and shall remain in full force and effect, regardless of
any investigation made by or on behalf of any of them or any person controlling
any of them.

         18. AGREEMENT BETWEEN UNDERWRITERS. Each of the Underwriters agrees
with the other that it will be liable for its proportionate share, based on the
proportion that is the number of shares set forth opposite such Underwriter's
name in Schedule 1 to the total number of shares to be purchased by the
Underwriters hereunder, of any losses, damages, liabilities or expenses
(collectively, the "LOSSES"), joint or several, paid or incurred by any
Underwriter to any person other than an Underwriter as a result of the offering
of shares contemplated herein, whether such losses arise under applicable
securities laws or otherwise, and including, without limitation, those losses
arising out of or based upon (i) any information or statement in any Preliminary


                                                                              37


Prospectus or the Prospectus or any other selling or advertising material
approved and used by the Underwriter in connection with the sale of the Shares
being a misrepresentation (as defined in the Securities Act (British Columbia)
or untrue, false or misleading; and (ii) any legal or other expenses reasonably
incurred by the Underwriter or any of them in connection with investigating or
defending any claim or action in respect of such losses.

         19. DEFINITION OF THE TERM "BUSINESS DAY." For purposes of this
Agreement, "BUSINESS DAY" means any day on which the New York Stock Exchange,
Inc. is open for trading.

         20. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the laws of New York.

         21. CONSENT TO JURISDICTION. Each party irrevocably agrees that any
legal suit, action or proceeding arising out of or based upon this Agreement or
the transactions contemplated hereby ("RELATED PROCEEDINGS") may be instituted
in the federal courts of the United States of America located in the City of New
York or the courts of the State of New York in each case located in the Borough
of Manhattan in the City of New York (collectively, the "SPECIFIED COURTS"), and
irrevocably submits to the non-exclusive jurisdiction of such courts in any such
suit, action or proceeding. The parties further agree that service of any
process, summons, notice or document by mail to such party's address set forth
above shall be effective service of process for any lawsuit, action or other
proceeding brought in any such court. The parties hereby irrevocably and
unconditionally waive any objection to the laying of venue of any lawsuit,
action or other proceeding in the Specified Courts, and hereby further
irrevocably and unconditionally waive and agree not to plead or claim in any
such court that any such lawsuit, action or other proceeding brought in any such

FORM LOCK-UP LETTER AGREEMENT

LEHMAN BROTHERS INC.,
CIBC WORLD MARKETS INC.
c/o LEHMAN BROTHERS INC.
745 Seventh Avenue
New York, NY   10019

Dear Sirs:

         The undersigned understands that you propose to enter into an
Underwriting Agreement (the "UNDERWRITING AGREEMENT") providing for the purchase
by you (the "UNDERWRITERS") of 4,000,000 common shares (the "FIRM SHARES") in
the capital of Sierra Wireless, Inc. (the "COMPANY"). In addition, the
undersigned understands that you will be granted an option to purchase up to
600,000 common shares in the capital of the Company (the "Option Shares"). The
undersigned understands that the Underwriters propose to reoffer the Firm Shares
and the Option Shares, if any, to the public (the "OFFERING").

         In consideration of the execution of the Underwriting Agreement by the
Underwriters, and for other good and valuable consideration, the undersigned
hereby irrevocably agrees that, without the prior written consent of Lehman
Brothers Inc., and CIBC World Markets Inc., such consent not to be unreasonably
withheld, the undersigned will not, directly or indirectly, (1) offer for sale,
sell, pledge, or otherwise dispose of (or enter into any transaction or device
that is designed to, or could be expected to, result in the disposition by any
person at any time in the future of) any common shares in the capital of the
Company (the "Shares") (including, without limitation, Shares that may be deemed
to be beneficially owned by the undersigned in accordance with the rules and
regulations of the Securities and Exchange Commission and Shares that may be
issued upon exercise of any option or warrant) or securities convertible into or
exchangeable for Shares owned by the undersigned on the date of execution of
this Lock-Up Letter Agreement or on the date of the completion of the Offering,
or (2) enter into any swap or other derivatives transaction that transfers to
another, in whole or in part, any of the economic benefits or risks of ownership
of such Shares, whether any such transaction described in clause (1) or (2)
above is to be settled by delivery of Shares or other securities, in cash or
otherwise, for a period of ninety (90) days after the date of the final
Prospectus relating to the Offering.

         In furtherance of the foregoing, the Company and its Transfer Agent are
hereby authorized to decline to make any transfer of securities if such transfer
would constitute a violation or breach of this Lock-Up Letter Agreement.

         It is understood that, if the Company notifies you that it does not
intend to proceed with the Offering, if the Underwriting Agreement does not
become effective, or if the Underwriting Agreement (other than the provisions
thereof which survive termination) shall terminate or be terminated prior to
payment for and delivery of the Shares, we will be released from our obligations
under this Lock-Up Letter Agreement.





         The undersigned understands that the Company, the Underwriters and the
shareholders selling shares in the Offering will proceed with the Offering in
reliance on this Lock-Up Letter Agreement.

         The undersigned hereby represents and warrants that the undersigned has
full power and authority to enter into this Lock-Up Letter Agreement and that,
upon request, the undersigned will execute any additional documents necessary in
connection with the enforcement hereof. Any obligations of the undersigned shall
be binding upon the heirs, personal representatives, successors and assigns of
the undersigned.

                                        Very truly yours,
