                                                                  April 11, 2000

Needham & Company, Inc.
c/o CIBC World Markets Corp.
One World Financial Center
New York, New York  10281
On behalf of the Several
Underwriters named on
Schedule I attached hereto.

Ladies and Gentlemen:

          GSI Lumonics Inc., a corporation organized and existing under the laws
of New Brunswick, Canada (the "Company"), proposes, subject to the terms and
conditions contained herein, to sell to you and the other underwriters named on
Schedule I to this Agreement (the "Underwriters"), for whom you are acting as
Representatives (the "Representatives"), an aggregate of 4,000,000 shares (the
"Firm Shares") of the Company's common shares (the "Common Shares").  All of the
Firm Shares are to be issued and sold by the Company.  The respective amounts of
the Firm Shares to be purchased by each of the several Underwriters are set
forth opposite their names on Schedule I hereto. In addition, the Company and
the persons listed on Schedule II hereto (the "Selling Shareholders") propose to
grant to the Underwriters an option to purchase up to an aggregate of 600,000
additional Common Shares (the "Option Shares") from it and the Selling
Shareholders for the purpose of covering over-allotments in connection with the
sale of the Firm Shares.  Of the 600,000 Option Shares, up to 296,612 are first
to be sold by the Company and then up to 303,388 are to be sold by the Selling
Shareholders.  The Firm Shares and the Option Shares are together called the
"Shares."

          The public offering price per share for the Shares and the purchase
price per share for the Shares to be paid by the several Underwriters shall be
agreed upon by the Company, acting on behalf of itself and the Selling
Shareholders, and the Representatives, acting on behalf of the several
Underwriters, and such agreement shall be set forth in a separate written
instrument substantially in the form of Exhibit A hereto (the "Price
Determination Agreement").  The Price Determination Agreement may take the form
of an exchange of any standard form of written telecommunication among the
Company, the Selling Shareholders and the Representatives and shall specify such
applicable information as is indicated in Exhibit A hereto.  The offering of the
Shares will be governed by this Agreement, as supplemented by the Price
Determination Agreement.  From and after the date of the execution and delivery
of the Price


Determination Agreement, this Agreement shall be deemed to incorporate, and,
unless the context otherwise indicates, all references contained herein to "this
Agreement" and to the phrase "herein" shall be deemed to include, the Price
Determination Agreement.

            1.   Sale and Purchase of the Shares.
                 -------------------------------

          On the basis of the representations, warranties and agreements
contained in, and subject to the terms and conditions of, this Agreement:

            (a) The Company agrees to sell to each of the Underwriters, and each
       of the Underwriters agrees, severally and not jointly, to purchase from
       the Company, the number of Firm Shares set forth opposite the name of
       such Underwriter under the column "Number of Firm Shares to be Purchased
       from the Company" on Schedule I to this Agreement, subject to adjustment
       in accordance with Section 11 hereof.  The purchase price for the Firm
       Shares (the "Initial Price") shall be as set out in the Price
       Determination Agreement.

            (b) The Company and the Selling Shareholders grant to the several
       Underwriters an option to purchase, severally and not jointly, all or any
       part of the Option Shares at the Initial Price.  The number of Option
       Shares to be purchased by each Underwriter shall be the same percentage
       (adjusted by the Representatives to eliminate fractions) of the total
       number of Option Shares to be purchased by the Underwriter as such
       Underwriter is purchasing of the Firm Shares.  Such option may be
       exercised only to cover over-allotments in the sales of the Firm Shares
       by the Underwriters and may be exercised in whole or in part at any time
       on or before 12:00 noon, New York City time, on the business day before
       the Firm Shares Closing Date (as defined below), and from time to time
       thereafter within 30 days after the date of this Agreement, in each case
       upon written, facsimile or telegraphic notice, or verbal or telephonic
       notice confirmed by written, facsimile or telegraphic notice, by the
       Representatives to the Company no later than 12:00 noon, New York City
       time, on the business day before the Firm Shares Closing Date or at least
       two business days before the Option Shares Closing Date (as defined
       below), as the case may be, setting forth the number of Option Shares to
       be purchased and the time and date (if other than the Firm Shares Closing
       Date) of such purchase.  Such option, if exercised in part, shall first
       be satisfied by purchase of Option Shares to be sold by the Company and
       then by purchase of Option Shares to be sold by the Selling Shareholders,
       on a pro rata basis.

            (c) The Company understands that the Underwriters, other than
       Nesbitt Burns Inc. ("Nesbitt Burns"), propose to make a public offering
       of Shares in the United States and CIBC World Markets Inc. ("CIBC Inc."),
       the Canadian affiliate of CIBC World Markets Corp. and Nesbitt Burns,
       propose to make a public offering of Shares in Canada, as set out in the
       Prospectus (defined below), all as soon as the Representatives deem
       advisable after this Agreement has been executed and delivered.

                                      -2-


       CIBC Inc. and Nesbitt Burns shall offer Shares directly in Canada only as
       permitted by the Canadian Securities Laws (as hereinafter defined).

          2.     Delivery and Payment.  Delivery by the Company to the
                 --------------------
Representatives for the respective accounts of the Underwriters, and payment of
the purchase price by certified or official bank check or checks payable in New
York Clearing House (same day) funds or immediately available funds by wire
transfer drawn to the order of the Company for the shares purchased from the
Company, against delivery of the respective certificates therefor to the
Representatives, shall take place at the offices of CIBC World Markets Corp.,
One World Financial Center, New York, New York 10281, or such other location as
agreed to by the Company and the Representatives, at 10:00 a.m., New York City
time, on the fifth business day following the date of this Agreement, or at such
time on such other date, not later than 10 business days after the date of this
Agreement, as shall be agreed upon by the Company and the Representatives (such
time and date of delivery and payment are called the "Firm Shares Closing
Date").

          In the event the option with respect to the Option Shares is exercised
in whole or on one or more occasions in part, delivery by the Company and the
Selling Shareholders of the Option Shares to the Representatives for the
respective accounts of the Underwriters and payment of the purchase price
thereof in immediately available funds by wire transfer or by certified or
official bank check or checks payable in New York Clearing House (same day)
funds or immediately available funds by wire transfer to the Company and to the
Selling Shareholders for the shares purchased from the Selling Shareholders
shall take place at the offices specified above of CIBC World Markets Corp., or
such other location as agreed to by the Company and the Representatives, at the
time and on the date (which may be the same date as, but in no event shall be
earlier than, the Firm Shares Closing Date) specified in the notice referred to
in Section 1(b) (such time and date of delivery and payment are called the
"Option Shares Closing Date").  The Firm Shares Closing Date and the Option
Shares Closing Date are called, individually, a "Closing Date" and, together,
the "Closing Dates."

          Certificates evidencing the Shares shall be registered in such names
and shall be in such denominations as the Representatives shall request, in the
case of the Firm Shares, at least two full business days before the Firm Shares
Closing Date or, in the case of Option Shares, on the day of notice of exercise
of the option as described in Section l(b) and shall be made available to the
Representatives for checking and packaging, at such place as is designated by
the Representatives, on the full business day before the Firm Shares Closing
Date (or the Option Shares Closing Date in the case of the Option Shares).

          3.     Registration Statement and Prospectus; Public Offering.  The
                 ------------------------------------------------------
Company has prepared and filed in conformity with the requirements of the
Securities Act of 1933, as amended (the "Securities Act"), and the published
rules and regulations thereunder (the "Rules") adopted by the Securities and
Exchange Commission (the "Commission") a Registration Statement  (as hereinafter
defined) on Form S-3 (No. 333-32966), including a preliminary prospectus
relating to the Shares, and such amendments thereof as may have been required to
the

                                      -3-


date of this Agreement. Copies of such Registration Statement (including all
amendments thereof) and of the related U.S. Preliminary Prospectus (as
hereinafter defined) have heretofore been delivered by the Company to you. The
term "U.S. Preliminary Prospectus" means any preliminary prospectus (as
described in Rule 430 of the Rules) included at any time as a part of the
Registration Statement or filed with the Commission by the Company with the
consent of the Representatives pursuant to Rule 424(a) of the Rules. The term
"Registration Statement" as used in this Agreement means the initial
registration statement (including all exhibits, financial schedules and
information deemed to be a part of the Registration Statement through
incorporation by reference or otherwise), as amended at the time and on the date
it becomes effective (the "Effective Date") including the information (if any)
deemed to be part thereof at the time of effectiveness pursuant to Rule 430A of
the Rules. If the Company has filed an abbreviated registration statement to
register additional Shares pursuant to Rule 462(b) under the Rules (the "462(b)
Registration Statement") then any reference herein to the Registration Statement
shall also be deemed to include such 462(b) Registration Statement. The term
"U.S. Prospectus" as used in this Agreement means the prospectus in the form
included in the Registration Statement at the time of effectiveness; or, if Rule
430A of the Rules is relied on, the term U.S. Prospectus shall also include the
final prospectus filed with the Commission pursuant to Rule 424(b) of the Rules.
The Company also has prepared and filed with the Canadian securities regulatory
authorities in all the provinces of Canada (the "Qualifying Provinces") a
preliminary short form prospectus relating to the Shares (in the English and
French languages, as applicable, including any documents incorporated therein by
reference, the "Canadian Preliminary Prospectus") and has obtained from the
Ontario Securities Commission (the "OSC") a mutual reliance review system
decision document, evidencing that receipts of securities regulatory authorities
in each of the Qualifying Provinces have been issued in respect of the Canadian
Preliminary Prospectus.

          In addition, the Company (a) has prepared and filed with the Canadian
securities regulatory authorities in all of the Qualifying Provinces, a final
short form prospectus relating to the Shares (in the English and French
languages, as applicable, including any documents incorporated therein by
reference, the "Canadian Final Prospectus") omitting the PREP Information (as
hereinafter defined) in accordance with the rules and procedures established
pursuant to the Canadian Securities Administrators' National Policy No. 44
(incorporated by reference into Rule 44-1C (In the Matter of Rules for Shelf
Prospectus Offerings and for Pricing Offerings after the Prospectus is
Receipted)) for the pricing of securities after the final receipt for a
prospectus has been obtained (the "PREP Procedures") and (b) will prepare and
file, promptly after the execution and delivery of this Agreement, (i) with the
Canadian securities regulatory authorities in all of the Qualifying Provinces,
in accordance with the PREP Procedures, a supplemented prospectus setting forth
the PREP Information (in the English and French languages, as applicable,
including any documents incorporated therein by reference, the "Canadian
Supplemented Prospectus").  The information, if any, included in the Canadian
Supplemented Prospectus that is omitted from the Canadian Final Prospectus for
which a final receipt has been obtained from the OSC, but that is deemed under
the PREP Procedures to be incorporated by reference into the Canadian Final
Prospectus as of the date of the Canadian Supplemented Prospectus is referred to
herein as the "PREP Information".  The Canadian Final

                                      -4-


Prospectus for which a final receipt has been obtained from the OSC is herein
referred to as the "Canadian Prospectus," except that, if, after the execution
of this Agreement, a Canadian Supplemented Prospectus containing the PREP
Information is thereafter filed with the Canadian securities regulatory
authorities in all of the Qualifying Provinces, the term "Canadian Prospectus"
shall refer to such Canadian Supplemented Prospectus, including the documents
incorporated by reference therein. The U.S. Prospectus and the Canadian
Prospectus in the respective forms used to confirm sales of Shares are
hereinafter collectively referred to as the "Prospectus".

          The Company and the Selling Shareholders understand that the
Underwriters propose to make a public offering of the Shares, as set forth in
and pursuant to the U.S. Prospectus, as soon after the Effective Date and the
date of this Agreement as the Representatives deem advisable.  The Company and
the Selling Shareholders hereby confirm that the Underwriters and dealers have
been authorized to distribute or cause to be distributed each U.S. Preliminary
Prospectus and Canadian Preliminary Prospectus and are authorized to distribute
the U.S. Prospectus, the Canadian Final Prospectus and the Canadian Supplemented
Prospectus, as from time to time amended or supplemented if the Company
furnishes amendments or supplements thereto to the Underwriters in each case in
accordance with the rules and regulations governing the distribution in the
United States and Canada.

          4.     Covenants, Representations and Warranties of the Company.  The
                 --------------------------------------------------------
Company covenants, represents and warrants to each Underwriter as follows:

            (a) The Company shall, as soon as possible, comply with the PREP
       Procedures and file with the securities regulatory authorities in each of
       the Qualifying Provinces the Canadian Supplemented Prospectus relating to
       the Shares and otherwise fulfill and comply with, to the satisfaction of
       the Representatives, all applicable securities laws in each of the
       Qualifying Provinces and the respective regulations and rules under such
       laws together with applicable published policy statements of the Canadian
       Securities Administrators and the securities regulatory authorities in
       the Qualifying Provinces (the "Canadian Securities Laws") required to be
       fulfilled or complied with by the Company to enable the Shares to be
       lawfully distributed in the Qualifying Provinces through investment
       dealers or brokers registered as such in the Qualifying Provinces. These
       requirements shall be fulfilled in each of the Qualifying Provinces not
       later than 5:00 p.m. (Toronto Time) on the next business day following
       the date hereof, or by such later date or dates as may be determined by
       the Representatives in their sole discretion.

            (b) On the Effective Date, the Registration Statement (in such form
       as at the Effective Date) complied, and on the date of the U.S.
       Prospectus, the date any post-effective amendment to the Registration
       Statement becomes effective, the date any supplement or amendment to the
       U.S. Prospectus is filed with the Commission and each Closing Date, the
       Registration Statement and the U.S. Prospectus (and any amendment thereof
       or supplement thereto) will comply, in all material respects, with

                                      -5-


       the applicable provisions of the Securities Act and the Rules and the
       Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
       rules and regulations of the Commission thereunder. The Registration
       Statement did not, as of the Effective Date, contain any untrue statement
       of a material fact or omit to state any material fact required to be
       stated therein or necessary in order to make the statements therein not
       misleading; and on the Effective Date and the other dates referred to
       above neither the Registration Statement nor the U.S. Prospectus nor any
       amendment thereof or supplement thereto will contain any untrue statement
       of a material fact or will omit to state any material fact required to be
       stated therein or necessary in order to make the statements therein not
       misleading. When any related preliminary prospectus was first filed with
       the Commission (whether filed as part of the Registration Statement or
       any amendment thereto or pursuant to Rule 424(a) of the Rules) and when
       any amendment thereof or supplement thereto was first filed with the
       Commission, such preliminary prospectus as amended or supplemented
       complied in all material respects with the applicable provisions of the
       Securities Act and the Rules and did not contain any untrue statement of
       a material fact or omit to state any material fact required to be stated
       therein or necessary in order to make the statements therein not
       misleading. Notwithstanding the foregoing, none of the representations
       and warranties in this paragraph 4(b) shall apply to statements in, or
       omissions from, the Registration Statement or the Prospectus made in
       reliance upon, and in conformity with, information herein or otherwise
       furnished in writing by the Representatives on behalf of the several
       Underwriters expressly for use in the Registration Statement or the
       Prospectus. With respect to the preceding sentence, the Company
       acknowledges that the only information furnished in writing by the
       Representatives on behalf of the several Underwriters for use in the
       Registration Statement or the Prospectus are the sections with respect to
       "Underwriting" in the U.S. Prospectus and in the Canadian Prospectus
       (other than the information therein with respect to the Company's $13.1
       million credit facility) and information about orders and delivery on the
       inside covers thereof.

            (c) The Registration Statement is effective under the Securities
       Act; and no stop order preventing or suspending the effectiveness of the
       Registration Statement or suspending or preventing the use of the U.S.
       Prospectus has been issued; and no proceedings for that purpose have been
       instituted or, to the Company's knowledge after due inquiry are
       threatened under the Securities Act. Any required filing of the U.S.
       Prospectus and any supplement thereto pursuant to Rule 424(b) of the
       Rules has been or will be made in the manner and within the time period
       required by such Rule 424(b).

            (d) The documents incorporated by reference in the Registration
       Statement and the U.S. Prospectus, at the time they were filed with the
       Commission, complied in all material respects with the requirements of
       the Exchange Act and, when read together and with the other information
       in the Registration Statement and the U.S. Prospectus, do not contain an
       untrue statement of a material fact or omit to state a

                                      -6-


       material fact required to be stated therein or necessary in order to make
       the statements therein, in the light of the circumstances under which
       they were made, not misleading.

            (e) The financial statements of the Company (including all notes and
       schedules thereto) included or incorporated by reference in the
       Registration Statement, the U.S. Prospectus and the Canadian Prospectus
       present fairly, in all material respects, the financial position, the
       results of operations, the statements of cash flows and the statements of
       stockholders' equity and the other information purported to be shown
       therein of the Company at the respective dates and for the respective
       periods to which they apply in conformity with U.S. generally accepted
       accounting principles in the case of the U.S. Prospectus and Canadian
       generally accepted accounting principles in the case of the Canadian
       Prospectus, consistently applied throughout the periods involved, except
       as indicated therein.  The summary and selected financial data included
       in the U.S. Prospectus and the Canadian Prospectus present fairly the
       information shown therein as at the respective dates and for the
       respective periods specified; and the summary and selected financial data
       have been presented on a basis consistent with the consolidated financial
       statements so set forth in or incorporated by reference in the U.S.
       Prospectus and the Canadian Prospectus and other financial information.

            (f) Ernst & Young LLP and Arthur Andersen LLP, whose reports are
       filed with the Commission as a part of the Registration Statement, are
       and, during the periods covered by their reports, were independent public
       auditors as required by the Securities Act and the Rules.

            (g) The Company and each of its subsidiaries other than those
       subsidiaries that, in aggregate, total less than 10% of consolidated
       revenues and individually are less than 2% of consolidated revenues (the
       "Subsidiaries") is a corporation duly organized, validly existing and in
       good standing under the laws of the jurisdiction of its incorporation.
       The Company does not control directly or indirectly any entities, other
       than the Subsidiaries.  The Company and each Subsidiary is duly qualified
       to do business and is in good standing as a foreign corporation in each
       jurisdiction in which the nature of the business conducted by it or
       location of the assets or properties owned, leased or licensed by it
       requires such qualification, except for such jurisdictions where the
       failure to so qualify would not have a material adverse effect on the
       assets or properties, business, results of operations or financial
       condition of the Company and each of its subsidiaries, taken as a whole
       (a "Material Adverse Effect").  The Company and each of its Subsidiaries
       has all requisite corporate power and authority, and all necessary
       authorizations, approvals, consents, orders, licenses, certificates and
       permits of and from all governmental or regulatory bodies or any other
       person or entity (collectively, the "Permits"), to own, lease and license
       its assets and properties and conduct its business, all of which are
       valid and in full force and effect, as described in the Registration
       Statement and the Prospectus, except where the lack of such Permits,
       individually or in the aggregate, would not have a Material Adverse

                                      -7-


       Effect. The Company and each of its Subsidiaries has fulfilled and
       performed in all material respects all of its material obligations with
       respect to such Permits; and no event has occurred that could reasonably
       be expected to result in revocation or termination thereof or results in
       any other material impairment of the rights of the Company or any
       Subsidiaries, as the case may be thereunder.  Except as may be required
       under the Securities Act, Canadian Securities Laws and state and foreign
       Blue Sky laws, no other Permits are required on the part of the Company
       or any Subsidiary to enter into, deliver and perform this Agreement and
       to issue and sell the Shares.

            (h) The Company and each of its Subsidiaries owns or possesses
       adequate and enforceable rights to use all patents, trademarks, trademark
       applications, trade names, service marks, copyrights, copyright
       applications, licenses, know-how and other similar rights and proprietary
       knowledge (collectively, "Intangibles") described in the Prospectus as
       being owned by it necessary for the conduct of its business.  Except as
       expressly set forth in the Registration Statement and the Prospectus or
       as otherwise disclosed in writing to the Underwriters, neither the
       Company nor any of its Subsidiaries has received any notice of, or is
       aware of, any infringement of or conflict with asserted rights of others
       with respect to any Intangibles.

            (i) The Company and each of its Subsidiaries has good and marketable
       title in fee simple to all items of real property and good and marketable
       title to all personal property described in the Prospectus as being owned
       by it subject to defects that would not result in a Material Adverse
       Effect. Any real property and buildings described in the Prospectus as
       being held under lease by the Company and each of its Subsidiaries is
       held by it under valid, existing and enforceable leases, free and clear
       of all liens, encumbrances, claims, security interests and defects,
       except such as are described in the Registration Statement and the
       Prospectus or would not have a Material Adverse Effect.

            (j) Except as expressly set forth in the Registration Statement and
       the Prospectus, there are no litigation or governmental proceedings to
       which the Company or its Subsidiaries is subject or which is pending or,
       to the knowledge of the Company, threatened, against the Company or any
       of its Subsidiaries, which, individually or in the aggregate, might
       reasonably be expected to have a Material Adverse Effect, adversely
       affect the consummation of this Agreement or which is required to be
       disclosed in the Registration Statement and the Prospectus that is not so
       disclosed.

            (k) Subsequent to the respective dates as of which information is
       given in the Registration Statement and the Prospectus, except as
       described therein (a) there has not been any material adverse change with
       regard to the assets or properties, business, results of operations or
       financial condition of the Company; (b) neither the Company nor its
       Subsidiaries has sustained any loss or interference with its assets,
       businesses or properties (whether owned or leased) from fire, explosion,
       earthquake,

                                      -8-


       flood or other calamity, whether or not covered by insurance, or from any
       labor dispute or any court or legislative or other governmental action,
       order or decree which would have a Material Adverse Effect; and (c) since
       the date of the latest balance sheet included in the Registration
       Statement and the Prospectus, except as reflected therein, neither the
       Company nor its Subsidiaries has (i) issued any securities or incurred
       any liability or obligation, direct or contingent, for borrowed money,
       except such options or shares issued in the ordinary course of business
       under existing stock option or similar plans since the date referred to
       in the Prospectus, liabilities or obligations incurred in the ordinary
       course of business, (ii) entered into any material transaction not in the
       ordinary course of business or (iii) declared or paid any dividend or
       made any distribution on any shares of its stock or redeemed, purchased
       or otherwise acquired or agreed to redeem, purchase or otherwise acquire
       any shares of its stock.

            (l) There is no document, contract or other agreement of a character
       required to be described in the Registration Statement or Prospectus or
       to be filed as an exhibit to the Registration Statement which is not
       described or filed as required by the Securities Act, the Rules or
       Canadian Securities Laws.  Each description of a contract, document or
       other agreement in the Registration Statement and the Prospectus
       accurately reflects in all material respects the terms of the underlying
       document, contract or agreement.  Each agreement described in the
       Registration Statement and Prospectus or listed in the Exhibits to the
       Registration Statement or incorporated by reference to which the Company
       or a Subsidiary is a party, subject to customary exceptions, is in full
       force and effect and is valid and enforceable by and against the Company
       or a Subsidiary, as the case may be, in accordance with its terms.
       Neither the Company nor any Subsidiary, if such Subsidiary is a party,
       nor to the Company's knowledge, any other party is in default in the
       observance or performance of any term or obligation to be performed by it
       under any such agreement, and no event has occurred which with notice or
       lapse of time or both would constitute such a default, in any such case
       which default or event, individually or in the aggregate, would have a
       Material Adverse Effect.  No default exists, and no event has occurred
       which with notice or lapse of time or both would constitute a default, in
       the due performance and observance of any term, covenant or condition, by
       the Company or any Subsidiary, if such Subsidiary is a party thereto, of
       any other agreement or instrument to which the Company or such Subsidiary
       is a party or by which the Company, any Subsidiary or their respective
       properties or business may be bound or affected which default or event,
       individually or in the aggregate, would have a Material Adverse Effect.

            (m) Neither the Company nor any of its Subsidiaries is in violation
       of any term or provision of its charter or by-laws or of any franchise,
       license, permit, judgment, decree, order, statute, rule or regulation,
       where the consequences of such violation, individually or in the
       aggregate, would have a Material Adverse Effect.

                                      -9-


            (n) Neither the execution, delivery and performance of this
       Agreement by the Company nor the consummation of any of the transactions
       contemplated hereby (including, without limitation, the issuance and sale
       by the Company of the Shares) will give rise to a right to terminate or
       accelerate the due date of any payment due under, or conflict with or
       result in the breach of any term or provision of, or constitute a default
       (or an event which with notice or lapse of time or both would constitute
       a default) under, or require any consent or waiver under, or result in
       the execution or imposition of any lien, charge or encumbrance upon any
       properties or assets of the Company or any Subsidiary pursuant to the
       terms of, any indenture, mortgage, deed of trust or other agreement or
       instrument to which the Company or any Subsidiary is a party or by which
       either the Company or any Subsidiary or any of their respective
       properties or businesses is bound, or any franchise, license, permit,
       judgment, decree, order, statute, rule or regulation applicable to the
       Company or any Subsidiary or violate any provision of the charter or by-
       laws of the Company or any Subsidiary, except for such consents or
       waivers which have already been obtained and are in full force and effect
       or which if not obtained would not have a Material Adverse Effect.

            (o) The Company has authorized and outstanding capital stock as set
       forth under the caption "Capitalization" in the Prospectus.  The
       certificates evidencing the Shares are in due and proper legal form and
       have been duly authorized for issuance by the Company.  All of the issued
       and outstanding Common Shares have been duly and validly issued and are
       fully paid and nonassessable.  There are no statutory preemptive or other
       similar rights to subscribe for or to purchase or acquire any Common
       Shares of the Company or any Subsidiaries or any such rights pursuant to
       their certificate of incorporation, articles or by-laws or any agreement
       or instrument to or by which the Company or any of its Subsidiaries is a
       party or bound.  The Shares, when issued and sold pursuant to this
       Agreement, will be duly and validly issued, fully paid and nonassessable;
       and none of them will be issued in violation of any preemptive or other
       similar right.  Except as disclosed in the Registration Statement and the
       Prospectus, there is no outstanding option, warrant or other right
       calling for the issuance of, and there is no commitment, plan or
       arrangement to issue, any shares of the Company or any Subsidiaries or
       any security convertible into, or exercisable or exchangeable for, such
       shares other than options or shares issued in the ordinary course of
       business under existing stock option or similar plans since the date
       referred to in the Prospectus.  The Common Shares and the Shares conform
       in all material respects to all statements in relation thereto contained
       in the Registration Statement and the Prospectus.  All outstanding shares
       of capital stock of each Subsidiary have been duly authorized and validly
       issued, and are fully paid and nonassessable and are owned directly by
       the Company or by another wholly owned subsidiary of the Company, free
       and clear of any security interests, liens, encumbrances, equities or
       claims, other than those described in the Prospectus.

            (p) No holder of any security of the Company has the right to have
       any security owned by such holder included in the Registration Statement
       or to demand

                                      -10-


       registration of any security owned by such holder during the period
       ending 90 days after the date of this Agreement. Each director and
       officer of the Company and Sumitomo Heavy Industries Ltd. have delivered
       to the Representatives its or his written lock-up agreement in the form
       attached to this Agreement ("Lock-Up Agreement").

            (q) All necessary corporate action has been duly and validly taken
       by the Company to authorize the execution, delivery and performance of
       this Agreement and the issuance and sale of the Shares by the Company.
       This Agreement has been duly and validly authorized, executed and
       delivered by the Company and constitutes and will constitute the legal,
       valid and binding obligation of the Company enforceable against the
       Company in accordance with its terms, except as the enforceability
       thereof may be limited by bankruptcy, insolvency, reorganization,
       moratorium or other similar laws affecting the enforcement of creditors'
       rights generally and by general equitable principles.

            (r) Neither the Company nor any of its Subsidiaries are involved in
       any labor dispute nor, to the knowledge of the Company, is any such
       dispute threatened, which dispute would have a Material Adverse Effect.
       The Company is not aware of any existing or imminent labor disturbance by
       the employees of any of its principal suppliers or contractors which
       would have a Material Adverse Effect. The Company is not aware of any
       threatened or pending litigation between the Company or any of its
       Subsidiaries and any of its executive officers which, if adversely
       determined, could have a Material Adverse Effect and has not been
       informed that such officers will not remain in the employment of the
       Company.

            (s) No material transaction has occurred between or among the
       Company and any of its officers or directors or five percent shareholders
       or any affiliate or affiliates of any such officer or director or five
       percent shareholders that is required to be described in and is not
       described in the Registration Statement and the Prospectus.

            (t) The Company has not taken, nor will it take, directly or
       indirectly, any action designed to or which would reasonably be expected
       to cause or result in, or which has constituted or which would reasonably
       be expected to constitute, the stabilization or manipulation of the price
       of the Common Shares to facilitate the sale or resale of any of the
       Shares.

            (u) The Company and its Subsidiaries have filed all material
       federal, state, provincial, local and foreign tax returns which are
       required to be filed through the date hereof, or have received extensions
       thereof, and have paid all taxes shown on such returns and all
       assessments received by them to the extent that the same are material and
       have become due other than those taxes and assessments that are currently
       being challenged and for which a reserve has been taken. There are no tax
       audits or investigations pending, which if adversely determined would
       have a Material Adverse

                                      -11-


       Effect; nor are there any material proposed additional tax assessments
       against the Company or any of its Subsidiaries.

            (v) The Shares have been duly authorized for quotation on the
       National Association of Securities Dealers Automated Quotation ("Nasdaq")
       National Market System, subject to official Notice of Issuance and have
       been approved for listing on The Toronto Stock Exchange.

            (w) The books, records and accounts of the Company and its
       Subsidiaries accurately and fairly reflect, in reasonable detail, the
       transactions in, and dispositions of, the assets of, and the results of
       operations of, the Company and its Subsidiaries.  The Company and each of
       its Subsidiaries maintains a system of internal accounting controls
       sufficient to provide reasonable assurances that (i) transactions are
       executed in accordance with management's general or specific
       authorizations, (ii) transactions are recorded as necessary to permit
       preparation of financial statements in accordance with U.S. and Canadian
       generally accepted accounting principles and to maintain asset
       accountability, (iii) access to assets is permitted only in accordance
       with management's general or specific authorization and (iv) the recorded
       accountability for assets is compared with the existing assets at
       reasonable intervals and appropriate action is taken with respect to any
       differences.

            (x) The Company and its Subsidiaries are insured by insurers of
       recognized financial responsibility against such losses and risks and in
       such amounts as are customary in the businesses in which it or they are
       engaged; all policies of insurance and fidelity or surety bonds insuring
       the Company or any of its Subsidiaries or the Company's or its
       Subsidiaries' respective businesses, assets, employees, officers and
       directors are in full force and effect; the Company and each of its
       Subsidiaries are in compliance with the terms of such policies and
       instruments in all material respects; and neither the Company nor any
       Subsidiary of the Company believes that it will not be able to renew its
       existing insurance coverage as and when such coverage expires or to
       obtain similar coverage from similar insurers as may be necessary to
       continue its business at a cost that would not have a Material Adverse
       Effect.

            (y) Each approval, consent, order, authorization, designation,
       declaration or filing of, by or with any regulatory, administrative or
       other governmental body necessary in connection with the execution and
       delivery by the Company of this Agreement and the consummation of the
       transactions herein contemplated required to be obtained or performed by
       the Company (except such additional steps as may be required by the
       National Association of Securities Dealers, Inc. (the "NASD") or may be
       necessary to qualify the Shares for public offering by the Underwriters
       under the state securities or Blue Sky laws) has been obtained or made
       and is in full force and effect.

                                      -12-


            (z) To the best of the knowledge of the Company, there are no
       affiliations with the NASD among the Company's officers, directors or,
       any five percent or greater stockholder of the Company, except as set
       forth in the Registration Statement or otherwise disclosed in writing to
       the Representatives.

           (aa) (i) Each of the Company and its Subsidiaries is in compliance
       with all rules, laws and regulations relating to the use, treatment,
       storage and disposal of toxic substances and protection of health or the
       environment ("Environmental Law") which are applicable to its business
       except for non-compliance that would not have a Material Adverse Effect;
       (ii) neither the Company nor any of its Subsidiaries has received any
       notice from (x) any third party of an asserted claim under Environmental
       Laws which would have a Material Adverse Effect, or (y) any governmental
       authority of an asserted claim under Environmental Laws; (iii) each of
       the Company and its Subsidiaries has received all permits, licenses or
       other approvals required of it under applicable Environmental Laws to
       conduct its business, except where the failure to obtain such permit,
       license or approval would not have a Material Adverse Effect, and is in
       compliance with all terms and conditions of any such permit, license or
       approval; (iv) to the Company's knowledge, no facts currently exist that
       will require the Company or any of its Subsidiaries to make future
       material capital expenditures to comply with Environmental Laws; and (v)
       no property which is or has been owned, leased or occupied by the Company
       or its Subsidiaries has been designated as a Superfund site pursuant to
       the Comprehensive Environmental Response, Compensation, and Liability Act
       of 1980, as amended (42 U.S.C. Section 9601, et. seq.) ("CERCLA"), or
       otherwise designated as a contaminated site under applicable state,
       provincial or local law. Neither the Company nor any of its Subsidiaries
       has been named as a "potentially responsible party" under CERCLA.

            (bb) In the ordinary course of its business, the Company
       periodically reviews the effect of Environmental Laws on the business,
       operations and properties of the Company and its Subsidiaries, in the
       course of which the Company identifies and evaluates associated costs and
       liabilities (including, without limitation, any capital or operating
       expenditures required for clean-up, closure of properties or compliance
       with Environmental Laws, or any permit, license or approval, any related
       constraints on operating activities and any potential liabilities to
       third parties). On the basis of such review, the Company has in good
       faith concluded that such associated costs and liabilities would not,
       singly or in the aggregate, have a Material Adverse Effect.

            (cc) The Company is not and, after giving effect to the offering and
       sale of the Shares and the application of proceeds thereof as described
       in the Prospectus, will not be an "investment company" within the meaning
       of the Investment Company Act of 1940, as amended (the "Investment
       Company Act").

            (dd) None of the Company, any of its Subsidiaries or any other
       person acting on behalf of the Company or any of its Subsidiaries,
       including, without

                                      -13-


       limitation, any director, officer, agent or employee of the Company or
       any of its Subsidiaries has directly or indirectly, while acting on
       behalf of the Company or any of its Subsidiaries (i) used any corporate
       funds for unlawful contributions, gifts, entertainment or other unlawful
       expenses relating to political activity; (ii) made any unlawful payment
       to foreign or domestic government officials or employees or to foreign or
       domestic political parties or campaigns from corporate funds; (iii)
       violated any provision of the Foreign Corrupt Practices Act of 1977, as
       amended; or (iv) made any other unlawful payment; except to the extent
       that any such unlawful contribution, payment or act would not be
       material.

            (ee) The Company shall use the net proceeds of the offering of the
       Shares to be sold by it pursuant to this Agreement in the manner
       specified in the Prospectus under the caption "Use of Proceeds".

            (ff) The Company is eligible to use the PREP Procedures and a
       receipt has been obtained from the OSC in respect of the Canadian
       Prospectus.

            (gg) Filing of the Canadian Preliminary Prospectus, the Canadian
       Final Prospectus and the Canadian Supplemented Prospectus shall
       constitute a representation and warranty by the Company to the
       Underwriters that as of the date of filing:

                    (i) all information and statements (except information
                relating solely to the Underwriters) contained in the Canadian
                Final Prospectus or the Canadian Supplemented Prospectus, as the
                case may be, including the documents incorporated therein by
                reference and any other management information circular,
                financial statements or material change reports (other than
                confidential material change reports) filed by the Company with
                any securities regulatory authority in any of the Qualifying
                Provinces after the date of the Canadian Prospectus and prior to
                the termination of the distribution of the Shares (collectively,
                the "Documents Incorporated by Reference"), are true and correct
                and contain no misrepresentation and constitute full, true and
                plain disclosure of all material facts relating to the Company
                and the Shares;

                    (ii) no material fact or information has been omitted from
                such disclosure (except facts or information relating solely to
                the Underwriters) which is required to be stated in such
                disclosure or is necessary to make the statements or information
                contained in such disclosure not misleading in light of the
                circumstances under which they were made; and

                    (iii) such documents comply fully with the requirements of
                the Canadian Securities Laws.

       Such filings shall also constitute the Company's consent to the
       Underwriters' use of the Canadian Preliminary Prospectus, Canadian Final
       Prospectus, the Documents

                                      -14-


       Incorporated by Reference and the Canadian Supplemented Prospectus in
       connection with distribution of the Shares in the Qualifying Provinces in
       compliance with the provisions of this Agreement and the Canadian
       Securities Laws.

                 --------------------------------------------------------
Shareholders.  Each Selling Shareholder hereby severally covenants, represents

and warrants to each Underwriter as follows:

            (a) Such Selling Shareholder (i) has caused certificates or (ii) has
       executed a Power of Attorney (as hereinafter defined) authorizing the
       person named therein to exercise such number of options and cause the
       certificates, for the number of Option Shares to be sold by such Selling
       Shareholder hereunder to be delivered to LaBarge Weinstein (the
       "Custodian"), endorsed in blank or with blank stock powers duly executed,
       with a signature appropriately guaranteed, such certificates to be held
       in custody by the Custodian for delivery, pursuant to the provisions of
       this Agreement and agreements dated March 2000 between the Custodian and
       each Selling Shareholder (together, the "Custody Agreement").

            (b) Such Selling Shareholder has granted an irrevocable power of
       attorney (the "Power of Attorney") to the person named therein, on behalf
       of such Selling Shareholder, to execute and deliver this Agreement and
       any other document necessary or desirable in connection with the
       transactions contemplated hereby and to deliver the Option Shares to be
       sold by the Selling Shareholder pursuant hereto.

            (c) This Agreement, the Custody Agreement, the Power of Attorney and
       the Lock-Up Agreement have each been duly authorized, executed and
       delivered by or on behalf of such Selling Shareholder and, assuming due
       authorization, execution and delivery by the other parties hereto or
       thereto, constitutes the valid and legally binding agreement of such
       Selling Shareholder, enforceable against such Selling Shareholder in
       accordance with its terms.  If a Selling Shareholder is an individual, he
       or she is of the age of majority, of sound mind and does not have the
       status of a bankrupt.

            (d) The execution and delivery by such Selling Shareholder of this
       Agreement and the performance by such Selling Shareholder of its
       obligations under this Agreement (i) will not contravene any provision of
       applicable law, statute, regulation or filing or any agreement or other
       instrument binding upon such Selling Shareholder or any judgment, order
       or decree of any governmental body, agency or court having jurisdiction
       over such Selling Shareholder, (ii) does not require any consent,
       approval, authorization or order of or registration or filing with any
       court or governmental agency or body having jurisdiction over it, except
       such as may be required by the Blue Sky laws of the various states in
       connection with the offer and sale of the Shares which have been or will
       be effected in accordance with this Agreement, (iii) does not and will
       not violate any statute, law, regulation or filing or judgment,
       injunction, order or decree applicable to such Selling Shareholder or
       (iv)

                                      -15-


       will not result in the creation or imposition of any lien, charge or
       encumbrance upon any property or assets of such Selling Shareholder
       pursuant to the terms of any agreement or instrument to which such
       Selling Shareholder is a party or by which such Selling Shareholder may
       be bound or to which any of the property or assets of such Selling
       Shareholder is subject in any case in such a manner as to impair the
       ability of such Selling Shareholder to perform this Agreement.

            (e) Such Selling Shareholder has (or upon exercise of such Selling
       Shareholder's options will have) valid and marketable title to the Option
       Shares to be sold by such Selling Shareholder free and clear of any lien,
       claim, security interest or other encumbrance, including, without
       limitation, any restriction on transfer other than restrictions on
       transfer  pursuant to the Lock-Up Agreement or securities laws (except
       that there is no restriction on transfer under securities laws in the
       case of the Option Shares in connection with this Offering).

            (f) Such Selling Shareholder has full legal right, power and
       authorization, and any approval required by law, to sell, assign,
       transfer and deliver the Option Shares to be sold by such Selling
       Shareholder in the manner provided by this Agreement.

            (g) Upon delivery of and payment for the Option Shares to be sold by
       such Selling Shareholder pursuant to this Agreement, the several
       Underwriters will receive valid and marketable title to such Option
       Shares free and clear of any lien, claim, security interest or other
       encumbrance other than as created or permitted to exist by the
       Underwriters.

            (h) All information relating to such Selling Shareholder furnished
       in writing by such Selling Shareholder expressly for use in the
       Registration Statement and the Prospectus is, and on each Closing Date
       will be, true, correct, and complete, and does not, and on each Closing
       Date will not, contain any untrue statement of a material fact or omit to
       state any material fact necessary to make such information not
       misleading.

            (i) Such Selling Shareholder has reviewed the Registration Statement
       and Prospectus and, although such Selling Shareholder has not
       independently verified the accuracy or completeness of all the
       information contained therein, nothing has come to the attention of such
       Selling Shareholder that causes such Selling Shareholder to believe that
       (i) on the Effective Date, the Registration Statement contained any
       untrue statement of a material fact or omitted to state any material fact
       required to be stated therein in order to make the statements made
       therein not misleading and (ii) on the Effective Date, the Prospectus
       contained and, on each Closing Date contains, any untrue statement of a
       material fact or omitted or omits to state any material fact necessary in
       order to make the statements made therein, in the light of the

       is correct insofar as it relates to them and stating in effect that:

                 (i) in their opinion the audited financial statements and
              financial statement schedules included or incorporated by
              reference in the Registration Statement, the U.S. Prospectus and
              the Canadian Prospectus and reported on by them comply as to form
              in all material respects with the applicable accounting
              requirements of the Securities Act and the Rules and Canadian
              Securities Laws, as applicable;

                 (ii) on the basis of a reading of the amounts included in the
              Registration Statement and the U.S. Prospectus or incorporated by
              reference in the Canadian Prospectus under the headings "Summary
              Consolidated Financial Data" and "Selected Consolidated Financial
              Data," carrying out certain procedures (but not an examination in
              accordance with generally accepted

                                      -18-


              auditing standards) which would not necessarily reveal matters of
              significance with respect to the comments set forth in such
              letter, a reading of the minutes of the meetings of the
              stockholders and directors of the Company, and inquiries of
              certain officials of the Company who have responsibility for
              financial and accounting matters of the Company as to transactions
              and events subsequent to the date of the latest audited financial
              statements, except as disclosed in the Registration Statement and
              the Prospectus, nothing came to their attention which caused them
              to believe that:

                       (A) the amounts in "Summary Consolidated Financial Data,"
                     and "Selected Consolidated Financial Data" included in the
                     Registration Statement and the Prospectus do not agree with
                     the corresponding amounts in the audited and unaudited
                     financial statements from which such amounts were derived;
                     or

                       (B) with respect to the Company, there were, at a
                     specified date not more than three business days prior to
                     the date of the letter, any increases in the current
                     liabilities and long-term liabilities of the Company or any
                     decreases in net income or in working capital or the
                     stockholders' equity of the Company, as compared with the
                     amounts shown on the Company's audited balance sheet for
                     the fiscal year ended December 31, 1999 included in the
                     Registration Statement and U.S. Prospectus and incorporated
                     by reference in the Canadian Prospectus;

                 (iii)  they have performed certain other procedures as may be
              permitted under generally acceptable auditing standards as a
              result of which they determined that certain information of an
              accounting, financial or statistical nature (which is limited to
              accounting, financial or statistical information derived from the
              general accounting records of the Company) set forth in the
              Registration Statement and the Prospectus and reasonably specified
              by the Representatives agrees with the accounting records of the
              Company; and

                 (iv) based upon the procedures set forth in Sections 6(g)(ii)
              and (iii) above and a reading of the amounts included in the
              Registration Statement under the headings "Summary Consolidated
              Financial Data" and "Selected Consolidated Financial Data"
              included in the Registration Statement and the Prospectus and a
              reading of the financial statements from which certain of such
              data were derived, nothing has come to their attention that gives
              them reason to believe that the "Summary Consolidated Financial"
              and "Selected Consolidated Financial Data" included in the
              Registration Statement and the Prospectus do not comply as to the
              form in all material respects with the applicable accounting
              requirements of the Securities Act, Canadian Securities

                                      -19-


              Laws and the Rules or that the information set forth therein is
              not fairly stated in relation to the financial statements included
              in the Registration Statement or the Prospectus from which certain
              of such data were derived.

                 References to the Registration Statement and the Prospectus in
              this Section 6(g) are to such documents as amended and
              supplemented at the date of the letter.

            (h) The Representatives shall have received on each Closing Date
       from Milbank, Tweed, Hadley & McCloy LLP, U.S. counsel for the Company,
       an opinion, addressed to the Representatives and dated such Closing Date,
       and stating in effect that:

                 (i) Each of the Lock-Up Agreements, assuming it has been duly
              executed by the Company's stockholders, directors and officers and
              duly and validly delivered by such persons, constitutes the legal,
              valid and binding obligation of each such person enforceable
              against each such person in accordance with its terms, except as
              the enforceability thereof may be limited by applicable
              bankruptcy, insolvency, reorganization, moratorium or other
              similar laws affecting the enforcement of creditors' rights
              generally (and the possible judicial application of foreign laws
              or governmental action affecting the rights of creditors
              generally) and except as enforceability is subject to the
              application of general principles of equity (regardless of whether
              considered in a proceeding in equity or at law), including,
              without limitation, (a) the possible unavailability of specific
              performance, injunctive relief or any other equitable remedy and
              (b) concepts of materiality, reasonableness, good faith and fair
              dealing.

                 (ii) No consent, approval, authorization or order of any New
              York or United States Federal court or governmental agency or
              regulatory body is required for the execution, delivery or
              performance of this Agreement by the Company or the consummation
              of the transactions contemplated hereby, except such as have been
              obtained under the Securities Act and such as may be required
              under state securities or Blue Sky laws in connection with the
              purchase and distribution of the Shares by the several
              Underwriters.

                 (iii)  The statements in the U.S. Prospectus under the caption
              "Tax Considerations," excluding "Canadian Tax Considerations"
              insofar as such statements constitute a summary of documents
              referred to therein or matters of law, are fair summaries in all
              material respects and accurately present the information called
              for with respect to such documents and matters.

                 (iv) The Registration Statement, all preliminary prospectuses
              and the U.S. Prospectus and each amendment or supplement thereto
              (except for the

                                      -20-


              financial statements and schedules and other financial and
              statistical data included therein, as to which such counsel need
              express no opinion) comply as to form in all material respects
              with the requirements of the Securities Act and the Rules.

                 (v) The Registration Statement is effective under the
              Securities Act, and no stop order suspending the effectiveness of
              the Registration Statement has been issued and to such counsel's
              knowledge no proceedings for that purpose have been instituted or
              are threatened, pending or contemplated.  Any required filing of
              the U.S. Prospectus and any supplement thereto pursuant to Rule
              424(b) under the Securities Act has been made in the manner and
              within the time period required by such Rule 424(b).

                 (vi) The Company is not an "investment company" or an entity
              controlled by an "investment company" as such terms are defined in
              the Investment Company Act of 1940.

          To the extent deemed advisable by such counsel, they may rely as to
matters of fact on certificates of responsible officers of the Company and
public officials and on the opinions of other counsel satisfactory to the
Representatives as to matters which are governed by laws other than the laws of
the State of New York, the General Corporation Law of the State of Delaware and
the federal laws of the United States; provided that such counsel shall state
that in their opinion that the Underwriters and they are justified in relying on
such other opinions.  Copies of such certificates and other opinions shall be
furnished to the Representatives and counsel for the Underwriters.



          In addition, such counsel shall state that such counsel has
participated in conferences with officers and other representatives of the
Company, representatives of the Representatives and representatives of the
independent certified public accountants of the Company, at which conferences
the contents of the Registration Statement and the Prospectus and related
matters were discussed and, although such counsel is not passing upon and does
not assume any responsibility for the accuracy, completeness or fairness of the
statements contained in the Registration Statement and the Prospectus (except as
specified in the foregoing opinion), on the basis of the foregoing, no facts
have come to the attention of such counsel which cause such counsel to believe
that the Registration Statement at the time it became effective (except with
respect to the financial statements and notes and schedules thereto and other
financial data, as to which such counsel need express no belief) contained any
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 the Prospectus as amended or supplemented (except with respect to the
financial statements, notes and schedules thereto and other financial data, as
to which such counsel need make no statement) on the date thereof contained any
untrue statement of a material fact or

                                      -21-


       omitted to state a material fact necessary in order to make the
       statements therein, in the light of the circumstances under which they
       were made, not misleading.

            (i) The Representatives shall have received on each Closing Date
       from LaBarge Weinstein or Stewart McKelvy Stirling Scales, each Canadian
       counsel for the Company, an opinion, addressed to the Representatives and
       dated such Closing Date, and stating in effect that:

                 (i) The Company has been duly continued and is validly existing
              as a corporation under the laws of its jurisdiction of
              continuance.  The Company is duly qualified and in good standing
              as a foreign corporation in each jurisdiction in which the
              character or location of its assets or properties (owned, leased
              or licensed) or the nature of its businesses makes such
              qualification necessary, except for such jurisdictions where the
              failure to so qualify, individually or in the aggregate, would not
              have a Material Adverse Effect.

                 (ii) The Company has all requisite corporate power and
              authority to own, lease and license its assets and properties and
              conduct its business as now being conducted and as described in
              the Registration Statement, the U.S. Prospectus and the Canadian
              Prospectus and with respect to the Company to enter into, deliver
              and perform this Agreement and to issue and sell the Shares other
              than those required under the state and foreign Blue Sky laws.

                 (iii)  The Company has authorized and issued capital stock as
              set forth in the Registration Statement and the Prospectus under
              the caption "Capitalization"; the certificates evidencing the
              Shares are in due and proper legal form and have been duly
              authorized for issuance by the Company; all of the outstanding
              Common Shares of the Company have been duly and validly authorized
              and issued and are fully paid and nonassessable and none of them
              was issued in violation of any preemptive or other similar right.
              The Shares when issued and sold pursuant to this Agreement will be
              duly and validly issued, outstanding, fully paid and nonassessable
              and none of them will have been issued in violation of any
              preemptive or other similar right.   To the best of such counsel's
              knowledge, except as disclosed in the Registration Statement and
              the Prospectus, there are no preemptive or other rights to
              subscribe for or to purchase or any restriction upon the voting or
              transfer of any securities of the Company pursuant to the
              Company's Memorandum of Association, articles or by-laws or other
              governing documents or any agreements or other instruments to
              which the Company is a party or by which it is bound. To the best
              of such counsel's knowledge, except as disclosed in the
              Registration Statement and the Prospectus, there is no outstanding
              option, warrant or other right calling for the issuance of, and no
              commitment, plan or arrangement to issue, any shares of stock of
              the Company or any security convertible into,

                                      -22-


              exercisable for, or exchangeable for stock of the Company other
              than as may have been issued in the ordinary course since the date
              thereof. The Common Shares conform in all material respects to the
              descriptions thereof contained in the Registration Statement and
              the Prospectus.

                 (iv) All necessary corporate action has been duly and validly
              taken by the Company to authorize the execution, delivery and
              performance of this Agreement and the issuance and sale of the
              Shares.  This Agreement has been duly and validly authorized,
              executed and delivered by the Company, and this Agreement
              constitutes the legal, valid and binding obligation of the
              Company.

                 (v) To the best of such counsel's knowledge, neither the
              execution, delivery and performance of this Agreement by the
              Company nor the consummation of any of the transactions
              contemplated hereby (including, without limitation, the issuance
              and sale by the Company of the Shares) will give rise to a right
              to terminate or accelerate the due date of any payment due under,
              or conflict with or result in the breach of any term or provision
              of, or constitute a default (or any event which with notice or
              lapse of time, or both, would constitute a default) under, or
              require consent or waiver under, or result in the execution or
              imposition of any lien, charge, claim, security interest or
              encumbrance upon any properties or assets of the Company or any of
              the Subsidiaries pursuant to the terms of any indenture, mortgage,
              deed of trust, note or other agreement or instrument of which such
              counsel is aware and to which the Company or any of the
              Subsidiaries is a party or by which either the Company or any of
              the Subsidiaries or any of its respective properties or businesses
              is bound, or any franchise, license, permit, judgment, decree,
              order, statute, rule or regulation of which such counsel is aware
              or violate any provision of the charter or by-laws of the Company.

                 (vi) To the best of such counsel's knowledge, no default
              exists, and no event has occurred which with notice or lapse of
              time, or both, would constitute a default, in the due performance
              and observance of any term, covenant or condition by the Company
              or any of the Subsidiaries of any indenture, mortgage, deed of
              trust, note or any other agreement or instrument to which the
              Company or any of the Subsidiaries is a party or by which it or
              any of the Subsidiaries or any of their respective assets or
              properties or businesses may be bound or affected, where the
              consequences of such default, individually or in the aggregate,
              would have a Material Adverse Effect.

                 (vii)  To the best of such counsel's knowledge, the Company is
              not in violation of any term or provision of its charter or by-
              laws and is not in violation of any terms or provisions of any
              franchise, license, permit, judgment, decree, order, statute, rule
              or regulation, where the consequences of

                                      -23-


              such violation, individually or in the aggregate, would have a
              Material Adverse Effect.

                 (viii)  No consent, approval, authorization or order of any
              court or governmental agency or regulatory body is required for
              the execution, delivery or performance of this Agreement by the
              Company or the consummation of the transactions contemplated
              hereby, except such as have been obtained under the Canadian
              Securities Laws in connection with the purchase and distribution
              of the Shares by the several Underwriters.

                 (ix) To the best of such counsel's knowledge, there is no
              litigation or governmental or other proceeding or investigation,
              before any court or before or by any public body or board pending
              or threatened against, or involving the assets, properties or
              businesses of, the Company or any of the Subsidiaries which would
              have a Material Adverse Effect.

                 (x) The statements in the U.S. Prospectus under the caption
              "Tax Considerations," excluding "U.S. Tax Considerations" and in
              the Canadian Prospectus under the caption "Certain Canadian
              Federal Income Tax Considerations" insofar as such statements
              constitute a summary of documents referred to therein or matters
              of law, are fair summaries in all material respects and accurately
              present the information called for with respect to such documents
              and matters.

                 (xi) All of the documents incorporated by reference in the
              Canadian Prospectus have been filed (in English and French, as
              applicable) in each of the Qualifying Provinces.

                 (xii)  The Canadian Supplemented Prospectus, Canadian Final
              Prospectus and the Canadian Preliminary Prospectus and each
              amendment or supplement thereto (except for the financial
              statements and schedules and other financial and statistical data
              included therein, as to which such counsel need express no
              opinion) comply as to form in all material respects with the
              requirements of the Canadian Securities Laws.

                 (xiii)  All necessary documents and proceedings have been filed
              and taken and all other legal requirements have been fulfilled
              under the laws of each of the provinces of Canada to qualify the
              Shares to be offered and sold to the public in each province of
              Canada by or through registrants, investment dealers or brokers
              registered under applicable legislation of such provinces who have
              complied with the relevant provisions of such legislation.

                                      -24-


                 (xiv)  Montreal Trust Company of Canada has been duly appointed
              the registrar and transfer agent of the Shares at its principal
              transfer office in the cities of Toronto.

                 (xv) The Shares have been approved for listing on The Toronto
              Stock Exchange.

                 (xvi)  The capital stock of the Company conforms in all
              material respects to the description thereof contained in the
              Prospectus under the caption "Description of Common Shares."

          To the extent deemed advisable by such counsel, they may rely as to
       matters of fact on certificates of responsible officers of the Company
       and public officials and on the opinions of other counsel satisfactory to
       the Representatives as to matters which are governed by laws other than
       the laws of the Province of Ontario and the federal laws of Canada
       provided that such counsel shall state that in their opinion the
       Underwriters and they are justified in relying on such other opinions.
       Copies of such certificates and other opinions shall be furnished to the
       Representatives and counsel for the Underwriters.

          In addition, such counsel shall state that such counsel has
       participated in conferences with officers and other representatives of
       the Company, representatives of the Representatives and representatives
       of the independent certified public accountants of the Company, at which
       conferences the contents of the Registration Statement and the Prospectus
       and related matters were discussed and, although such counsel is not
       passing upon and does not assume any responsibility for the accuracy,
       completeness or fairness of the statements contained in the Registration
       Statement and the Prospectus (except as specified in the foregoing
       opinion), on the basis of the foregoing, no facts have come to the
       attention of such counsel which cause such counsel to believe that the
       Registration Statement at the time it became effective (except with
       respect to the financial statements and notes and schedules thereto and
       other financial data, as to which such counsel need express no belief)
       contained any 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 the Prospectus as amended or
       supplemented (except with respect to the financial statements, notes and
       schedules thereto and other financial data, as to which such counsel need
       make no statement) on the date thereof contained any untrue statement of
       a material fact or omitted to state a material fact necessary in order to
       make the statements therein, in the light of the circumstances under
       which they were made, not misleading.

            (j) The Representatives shall have received on each Closing Date
       from counsel for the Company in the jurisdiction listed opposite the name
       of each of the Subsidiaries listed on Schedule III (the "Material
       Subsidiaries"), an opinion, addressed to the Representatives and dated
       such Closing Date, and stating in effect that:

                                      -25-


                 (i) Each Material Subsidiary has been duly organized and is
              validly existing as a corporation under the laws of its
              jurisdiction of incorporation.  Each such Material Subsidiary is
              duly qualified and in good standing as a foreign corporation in
              each jurisdiction in which the character or location of its assets
              or properties (owned, leased or licensed) or the nature of its
              businesses makes such qualification necessary, except for such
              jurisdictions where the failure to so qualify, individually or in
              the aggregate, would not have a Material Adverse Effect.

                 (ii) Each such Material Subsidiary has all requisite corporate
              power and authority to own, lease and license its assets and
              properties and conduct its business as now being conducted.

                 (iii)    The issued and outstanding shares of capital stock of
              each such Material Subsidiary have been duly authorized and
              validly issued, are fully paid and nonassessable and are owned by
              the Company or by another wholly owned subsidiary of the Company,
              free and clear of any perfected security interest or, to the
              knowledge of such counsel, any other security interests, liens,
              encumbrances, equities or claims, other than those described in
              the Registration Statement or the Prospectus.

                 (iv) To the best of such counsel's knowledge, there is no
              litigation or governmental or other proceeding or investigation,
              before any court or before or by any public body or board pending
              or threatened against, or involving the assets, properties or
              businesses of, such Material Subsidiary which would have a
              Material Adverse Effect.

              To the extent deemed advisable by such counsel, they may rely as
       to matters of fact on certificates of responsible officers of such
       Material Subsidiary and public officials. Copies of such certificates
       shall be furnished to the Representatives and counsel for the
       Underwriters.

            (k) The Representatives shall have received on each Option Shares
       Closing Date from Milbank, Tweed, Hadley & McCloy LLP an opinion,
       addressed to the Representatives and dated such Closing Date, and stating
       in effect that:

                   (i) Assuming that they have been duly and validly executed
           and delivered by or on behalf of the Selling Shareholders, this
           Agreement, the Custody Agreement, the Power of Attorney and the Lock-
           Up Agreement each constitutes the legal, valid and binding obligation
           of the Selling Shareholders enforceable against the Selling
           Shareholders in accordance with its terms except as such
           enforceability may be limited by applicable bankruptcy, insolvency,
           reorganization, moratorium or other similar laws affecting the

                                      -26-


           enforcement of creditors' rights generally (and the possible judicial
           application of foreign laws or governmental action affecting the
           rights of creditors generally) and except as enforceability is
           subject to the application of general principles of equity
           (regardless of whether considered in a proceeding in equity or at
           law), including, without limitation, (a) the possible unavailability
           of specific performance, injunctive relief or any other equitable
           remedy and (b) concepts of materiality, reasonableness, good faith
           and fair dealing.

                 (ii) To the extent that the laws of the State of New York or
           the federal laws of the United States applies, all of the Selling
           Shareholders' rights in the Option Shares to be sold by the Selling
           Shareholders pursuant to this Agreement, have been transferred to the
           Underwriters who have severally purchased such Option Shares pursuant
           to this Agreement, free and clear of adverse claims, assuming for
           purposes of this opinion that the Underwriters purchased the same in
           good faith without notice of any adverse claims.

                (iii) No consent, approval, authorization, license, certificate,
           permit or order of any New York or United States federal court,
           governmental or regulatory agency, authority or body is required in
           connection with the performance of this Agreement by the Selling
           Shareholders or the consummation of the transactions contemplated
           hereby, including the delivery and sale of the Option Shares to be
           delivered and sold by the Selling Shareholders, except such as may be
           required under state securities or Blue Sky laws in connection with
           the purchase and distribution of the Shares by the several
           Underwriters.

           To the extent deemed advisable by such counsel, they may rely as to
     matters of fact on certificates of the Selling Shareholders and on the
     opinions of other counsel satisfactory to the Representatives as to matters
     which are governed by laws other than the laws of the State of New York,
     the General Corporation Law of the State of Delaware or the federal laws of
     the United States in the case of Milbank, Tweed, Hadley & McCloy and the
     laws of the Province of Ontario and the federal laws of Canada applicable
     therein in the case of LaBarge Weinstein; provided that such counsel shall
     state that in their opinion the Underwriters and they are justified in
     relying on such other opinions. Copies of such certificates and other
     opinions shall be furnished to the Representatives and counsel for the
     Underwriters.

            (l) All proceedings taken in connection with the sale of the Firm
     Shares and the Option Shares as herein contemplated shall be reasonably
     satisfactory in form and substance to the Representatives, and their
     counsel and the Underwriters shall have received from Torys a favorable
     opinion, addressed to the Representatives and dated such Closing Date, with
     respect to the Shares, the Registration Statement and the Prospectus, and
     such other related matters, as the Representatives may reasonably

                                      -27-


       request, and the Company shall have furnished to Torys such documents as
       they may reasonably request for the purpose of enabling them to pass upon
       such matters.

            (m) The Representatives shall have received copies of the Lock-up
       Agreements executed by each entity or person described in Section 4(p).

            (n) The Company and the Selling Shareholders shall have furnished or
       caused to be furnished to the Representatives such further certificates
       or documents as the Representatives shall have reasonably requested.

            7.   Covenants of the Company.
                 ------------------------

            (a) The Company covenants and agrees as follows:

                 (i) The Company will use its best efforts to cause the
              Registration Statement, if not effective at the time of execution
              of this Agreement, and any amendments thereto, to become effective
              as promptly as possible.  The Company shall prepare the U.S.
              Prospectus in a form approved by the Representatives (such
              approval not to be unreasonably withheld) and file such U.S.
              Prospectus pursuant to Rule 424(b) under the Securities Act not
              later than the Commission's close of business on the second
              business day following the execution and delivery of this
              Agreement, or, if applicable, such earlier time as may be required
              by Rule 430A(a)(3) under the Securities Act.

                 (ii) The Company shall promptly advise the Representatives in
              writing (i) when any amendment to the Registration Statement shall
              have become effective, (ii) of any request by the Commission for
              any amendment of the Registration Statement or the U.S. Prospectus
              or for any additional information, (iii) of the prevention or
              suspension of the use of any preliminary prospectus or the U.S.
              Prospectus or of the issuance by the Commission of any stop order
              suspending the effectiveness of the Registration Statement or the
              institution or threatening of any proceeding known to it for that
              purpose and (iv) of the receipt by the Company of any notification
              with respect to the suspension of the qualification of the Shares
              for sale in any jurisdiction or the initiation or threatening of
              any proceeding for such purpose.  The Company shall not file any
              amendment of the Registration Statement or supplement to the
              Prospectus unless the Company has furnished the Representatives a
              copy for its review prior to filing and shall not file any such
              proposed amendment or supplement to which the Representatives
              reasonably object.  The Company shall use its best efforts to
              prevent the issuance of any such stop order and, if issued, to
              obtain as soon as possible the withdrawal thereof.

                 (iii)  If, at any time within one year after the date hereof
              when a prospectus relating to the Shares is required to be
              delivered under the

                                      -28-


              Securities Act and the Rules, any event occurs as a result of
              which the U.S. Prospectus as then amended or supplemented would
              include any untrue statement of a material fact or omit to state
              any material fact necessary to make the statements therein in the
              light of the circumstances under which they were made not
              misleading, or if it shall be necessary to amend or supplement the
              U.S. Prospectus to comply with the Securities Act or the Rules,
              the Company promptly shall prepare and file with the Commission,
              subject to the second sentence of paragraph (ii) of this Section
              7(a), an amendment or supplement which shall correct such
              statement or omission or an amendment which shall effect such
              compliance.

                 (iv) The Company shall make generally available to its security
              holders and to the Representatives as soon as practicable, but not
              later than 45 days after the end of the 12-month period beginning
              at the end of the fiscal quarter of the Company during which the
              Effective Date occurs (or 90 days if such 12-month period
              coincides with the Company's fiscal year), an earning statement
              (which need not be audited) of the Company, covering such 12-month
              period, which shall satisfy the provisions of Section 11(a) of the
              Securities Act or Rule 158 of the Rules.

                 (v) The Company shall furnish to the Representatives and
              counsel for the Underwriters, without charge, signed copies of the
              Registration Statement (including all exhibits thereto and
              amendments thereof) and to each other Underwriter a copy of the
              Registration Statement (without exhibits thereto) and all
              amendments thereof and, so long as delivery of a prospectus by an
              Underwriter or dealer may be required by the Securities Act or the
              Rules, as many copies of any preliminary prospectus and the
              Prospectus and any amendments thereof and supplements thereto as
              the Representatives may reasonably request.

                 (vi) The Company shall cooperate with the Representatives and
              their counsel in endeavoring to qualify the Shares for offer and
              sale to the extent required by law in connection with the offering
              under the laws of such jurisdictions as the Representatives may
              designate and shall maintain such qualifications in effect so long
              as required for the distribution of the Shares; provided, however,
              that the Company shall not be required in connection therewith, as
              a condition thereof, to qualify as a foreign corporation or to
              execute a general consent to service of process in any
              jurisdiction or subject itself to taxation as doing business in
              any jurisdiction.

                 (vii)  Without the prior written consent of  CIBC World Markets
              Corp., for a period of 90 days after the date of this Agreement,
              the Company shall not issue, sell or register with the Commission
              (other than on Form S-8 or on any successor form), or otherwise
              dispose of, directly or indirectly, any

                                      -29-


              equity securities of the Company (or any securities convertible
              into, exercisable for or exchangeable for equity securities of the
              Company), except for the issuance of the Shares pursuant to the
              Registration Statement and the issuance of options and shares
              pursuant to the Company's existing stock option plan or bonus plan
              or shareholder rights plan as described in the Registration
              Statement and the Prospectus. In the event that during this
              period, (i) any shares are issued pursuant to the Company's
              existing stock option plan or bonus plan or (ii) any registration
              is effected on Form S-8 or on any successor form relating to
              shares that are issuable during such 90 period, the Company shall
              obtain the written agreement of such grantee or purchaser or
              holder of such registered securities if it is a director or
              executive officer of the Company, that, for a period of 90 days
              after the date of this Agreement, such person will not, without
              the prior written consent of CIBC World Markets Corp. which would
              not be unreasonably withheld or delayed, offer for sale, sell,
              distribute, grant any option for the sale of, or otherwise dispose
              of, directly or indirectly, or exercise any registration rights
              with respect to, any shares of Common Shares (or any securities
              convertible into, exercisable for, or exchangeable for any shares
              of Common Shares) owned by such person.

                 (viii)  On or before completion of this offering, the Company
              shall make all filings required under applicable securities laws
              and by the Nasdaq National Market.

                 (ix) The Company will apply the net proceeds from the offering
              of the Shares in the manner set forth under "Use of Proceeds" in
              the Prospectus.

               Canadian Final Prospectus and the Canadian Supplemented
               Prospectus in the English language signed and certified as
               required by the Canadian Securities Laws applicable in the
               Qualifying Provinces other than Quebec;

               and substance satisfactory to the Underwriters, acting
               reasonably, dated in the case of the Canadian Preliminary

               Prospectus, in the case of the Canadian Final Prospectus, as of
               the date of the Canadian Final Prospectus, and, in the case of
               the Canadian Supplemented Prospectus, as of the date of the
               Canadian Supplemented Prospectus to the effect that the French
               language version of the Canadian Preliminary Prospectus, the
               Canadian Final Prospectus and the Canadian Supplemented
               Prospectus, including in each case the Documents Incorporated by
               Reference, as the case may be, except for the consolidated
               financial statements of the Company included in the Prospectus,
               together with the reports of Ernst & Young LLP on such financial
               statements as at and for the periods included in the Prospectus
               and including the notes with respect to such financial statements
               and Management's Discussion and Analysis of Financial Condition
               and Results of Operations included in the Prospectus (the
               "Financial Information") as to which no opinion need be
               expressed, is in all material respects a complete and accurate
               translation of the English language version thereof, and that
               such English and French language versions are not susceptible of
               any materially different interpretation with respect to any
               matter contained therein; and

                  (E) an opinion of Ernst & Young LLP addressed to the
               Underwriters, the Company, LaBarge Weinstein and Torys, dated in
               the case of the Canadian Preliminary Prospectus, as of the date
               of the Canadian Preliminary Prospectus, in the case of the
               Canadian Final Prospectus, as of the date of the Canadian Final
               Prospectus and, in the case of the Canadian Supplemented
               Prospectus, as of the date of the Canadian Supplemented
               Prospectus, to the effect that the French language version of the
               Financial Information is in all material respects, a complete and
               proper translation of the English language version thereof.

                (xi) During the period from the date of this Agreement to the
       completion of distribution of the Shares, to promptly notify, whether
       directly or through public announcement, the Underwriters in writing of:

                  (A) any material change (actual, anticipated, contemplated or
               threatened, financial or otherwise) known to it in the business,
               affairs, operations, assets, liabilities (contingent or
               otherwise) or capital of the Corporation and its Subsidiaries
               taken as a whole; or

                                      -31-


                  (B) any material fact which has arisen or been discovered and
               would have been required to have been stated in the Prospectus
               had the fact arisen or been discovered on, or prior to, the date
               of such document; and

       any change in any material fact (which for the purposes of this Agreement
       shall be deemed to include the disclosure of any previously undisclosed
       material fact) contained in the Canadian Prospectus or any Canadian
       Prospectus Amendment, including all Documents Incorporated by Reference,
       which fact or change is, or may be, of such a nature as to render any
       statements in the Prospectus misleading or untrue or which would result
       in a misrepresentation in the Prospectus or which would result in the
       Prospectus not complying (to the extent that such compliance is required)
       with the Canadian Securities Laws.

       The Company shall promptly, and in any event within any applicable time
       limitation, comply, to the reasonable satisfaction of the Underwriters,
       with all applicable filings and other requirements under the Canadian
       Securities Laws as a result of such fact or change. However, the Company
       shall not file any amendment to the Canadian Prospectus (a "Canadian
       Prospectus Amendment") or other document without first obtaining approval
       from the Underwriters, after consultation with the Underwriters with
       respect to the form and content thereof, which approval will not be
       unreasonably withheld. The Company shall in good faith discuss with the
       Underwriters any fact or change in circumstances (actual, anticipated,
       contemplated or threatened, financial or otherwise) which is of such a
       nature that there is reasonable doubt whether written notice need be
       given under this paragraph.

           (xii)    If during the period of distribution to the public of the
       Shares, there shall be any change in the Canadian Securities Laws which,
       in the opinion of the Underwriters, requires the filing of a Canadian
       Prospectus Amendment, the Company shall, to the satisfaction of the
       Underwriters, acting reasonably, promptly prepare and file such Canadian
       Prospectus Amendment with the appropriate securities regulatory authority
       in each of the Qualifying Provinces where such filing is required.

           (xiii)   When the Company is required to prepare or prepares any
       Canadian Prospectus Amendment, the Company shall also prepare and deliver
       promptly to each of the Underwriters signed and certified copies of all
       Canadian Prospectus Amendments in the English and French language which
       have not been previously delivered. The Canadian Prospectus Amendments
       shall be in form and substance satisfactory to the Underwriters acting
       reasonably. Concurrently with the delivery of any Canadian Prospectus
       Amendments, the Company shall deliver to each of the Underwriters, with
       respect to such Canadian Prospectus Amendments, documents similar to
       those

                                      -32-


       referred to in Sections 7(a)(xi)(C), (D) and (E). The Company shall
       promptly furnish the Underwriters, without charge, with commercial copies
       of the English and French language versions of such Canadian Prospectus
       Amendment, in such quantities and at such cities as the Representatives
       may from time to time reasonably request.

           (xiv)    To cause commercial copies of the Canadian Prospectus in the
       English and French languages to be delivered to the Underwriters without
       charge, in such numbers and in such cities as the Underwriters may
       reasonably request by oral instructions to the printer of the Prospectus
       given forthwith after the Underwriters have been advised that the Company
       has complied with the Canadian Securities Laws with respect to the filing
       thereof. Such delivery shall be effected as soon as possible and, in any
       event, on or before a date one Business Day after compliance with the
       Canadian Securities Laws with respect to the filing thereof.

       (b) The Company agrees to pay, or reimburse if paid by the
   Representatives, whether or not the transactions contemplated hereby are
   consummated or this Agreement is terminated, all costs and expenses incident
   to the performance of the obligations of the Company under this Agreement
   including those relating to: (i) the preparation, printing, filing and
   distribution of the Registration Statement including all exhibits thereto,
   each preliminary prospectus, the Prospectus, all amendments and supplements
   to the Registration Statement and the Prospectus if required during the one
   year period after the date hereof, and the printing, filing and distribution
   of this Agreement; (ii) the preparation and delivery of certificates for the
   Shares to the Underwriters; (iii) the registration or qualification of the
   Shares for offer and sale under the securities or Blue Sky laws of the
   various jurisdictions referred to in Section 7(a)(vi), including the
   reasonable fees and disbursements of counsel for the Underwriters in
   connection with such registration and qualification and the preparation,
   printing, distribution and shipment of preliminary and supplementary Blue Sky
   memoranda (of not more than U.S.$5,000); (iv) the furnishing (including costs
   of shipping and mailing) to the Representatives and to the Underwriters of
   copies of each preliminary prospectus, the Prospectus and all amendments or
   supplements to the Prospectus, and of the several documents required by this
   Section to be so furnished, as may be reasonably requested for use in
   connection with the offering and sale of the Shares by the Underwriters or by
   dealers to whom Shares may be sold; (v) the filing fees of the NASD in
   connection with its review of the terms of the public offering and reasonable
   fees and disbursements of counsel for the Underwriters in connection with
   such review; (vi) inclusion of the Shares for quotation on the Nasdaq
   National Market; (vii) all transfer taxes, if any, with respect to the sale
   and delivery of the Shares by the Company and the Selling Shareholders to the
   Underwriters; and (viii) all costs and expenses incident to listing the
   Shares on the Nasdaq National Market and The Toronto Stock Exchange. Subject
   to the provisions of Section 10, the Underwriters agree to pay, whether or
   not the transactions contemplated hereby are consummated or this Agreement is
   terminated, all costs and expenses incident to the

                                      -33-


       performance of the obligations of the Underwriters under this Agreement
       not payable by the Company pursuant to the preceding sentence, including,
       without limitation, the fees and disbursements of counsel for the
       Underwriters.

            8.  Indemnification.
                ----------------

            (a) The Company, and each Selling Shareholder agrees, jointly and
       severally, to indemnify and hold harmless each Underwriter and each
       person, if any, who controls any Underwriter within the meaning of
       Section 15 of the Securities Act or Section 20 of the Exchange Act or who
       is an affiliate of a Representative against any and all losses, claims,
       damages and liabilities, joint or several (including any reasonable
       investigation, legal and other expenses incurred in connection with, and
       any amount paid in settlement of, any action, suit or proceeding or any
       claim asserted), to which they, or any of them, may become subject under
       the Securities Act, the Exchange Act, Canadian Securities Laws or other
       federal, provincial or state law or regulation, at common law or
       otherwise, insofar as such losses, claims, damages or liabilities arise
       out of or are based upon any untrue statement or alleged untrue statement
       of a material fact contained in any preliminary prospectus, the
       Registration Statement or the Prospectus or any amendment thereof or
       supplement thereto required within one year from the date hereof, or in
       any Blue Sky application or other information or other documents executed
       by the Company filed in any state or other jurisdiction to qualify any or
       all of the Shares under the securities laws thereof (any such
       application, document or information being hereinafter referred to as a
       "Blue Sky Application") or arise out of or are based upon any omission or
       alleged omission to state therein a material fact required to be stated
       therein or necessary to make the statements therein not misleading;
       provided, however, that such indemnity shall not inure to the benefit of
       any Underwriter (or any person controlling such Underwriter) on account
       of any losses, claims, damages or liabilities arising from the sale of
       the Shares to any person by such Underwriter if such untrue statement or
       omission or alleged untrue statement or omission was made in such
       preliminary prospectus, the Registration Statement or the Prospectus, or
       such amendment or supplement thereto, or in any Blue Sky Application in
       reliance upon and in conformity with information furnished in writing to
       the Company by the Representatives on behalf of any Underwriter
       specifically for use therein; provided, further, that with respect to any
       such untrue statement or omission made in any preliminary prospectus, the
       indemnity agreement contained in this Section 8(a) shall not inure to the
       benefit of the Underwriter from whom the person asserting any such
       losses, claims, damages or liabilities purchased the Shares concerned if
       any such loss, claim, damage or liability of such Underwriter is a result
       of the fact that both (A) a copy of the Prospectus was not sent or given
       to such person at or prior to written confirmation of the sale of such
       Share to such person and (B) the untrue statement or omission in the
       preliminary prospectus was corrected in the Prospectus.  Notwithstanding
       the foregoing,

                                      -34-


       liability of any Selling Shareholder pursuant to the provisions of this
       Section 8(a) shall be limited to an amount equal to the aggregate net
       proceeds received by such Selling Shareholder from the sale of the Option
       Shares sold by such Selling Shareholders hereunder. This indemnity
       agreement will be in addition to any liability which the Company and
       Selling Shareholders may otherwise have.

            (b) Each Underwriter agrees, severally and not jointly, to indemnify
       and hold harmless the Company, the Selling Shareholders and each person,
       if any, who controls the Company within the meaning of Section 15 of the
       Securities Act or Section 20 of the Exchange Act, each director of the
       Company, and each officer of the Company who signs the Registration
       Statement, to the same extent as the foregoing indemnity from the
       Company, and the Selling Shareholders to each Underwriter, but only
       insofar as such losses, claims, damages or liabilities arise out of or
       are based upon any untrue statement or omission or alleged untrue
       statement or omission which was made in any preliminary prospectus, the
       Registration Statement or the Prospectus, or any amendment thereof or
       supplement thereto, contained in the sections with respect to
       "Underwriting" in the U.S. Prospectus and in the Canadian Prospectus
       (other than the information therein with respect to the Company's $13.1
       million credit facility) and information about orders and delivery on the
       inside covers thereof; provided however, that the obligation of each
       Underwriter to indemnify the Company or the Selling Shareholders
       (including any controlling person, director or officer thereof) shall be
       limited to the net proceeds received by the Company or the Selling
       Shareholder from such Underwriter.

            (c) Any party that proposes to assert the right to be indemnified
       under this Section 8 will, promptly after receipt of notice of
       commencement of any action, suit or proceeding against such party in
       respect of which a claim is to be made against an indemnifying party or
       parties under this Section 8, notify each such indemnifying party of the
       commencement of such action, suit or proceeding, enclosing a copy of all
       papers served.  No indemnification provided for in Section 8(a) or 8(b)
       shall be available to any party who shall fail to give notice as provided
       in this Section 8(c) if the party to whom notice was not given was
       unaware of the proceeding to which such notice would have related and was
       materially prejudiced by the failure to give such notice but the omission
       so to notify such indemnifying party of any such action, suit or
       proceeding shall not relieve it from any liability that it may have to
       any indemnified party for contribution or otherwise than under this
       Section 8.  In case any such action, suit or proceeding 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 in, and, to the extent that it shall wish, jointly with any
       other indemnifying party similarly notified, to assume the defense
       thereof, with counsel reasonably satisfactory to such indemnified party,
       and after notice from the indemnifying party to such indemnified party of
       its election so to assume the defense thereof and the approval by the
       indemnified party of such counsel, the indemnifying parties shall not be
       liable to such indemnified party for any legal or other expenses,

                                      -35-


       except as provided below and except for the reasonable costs of
       investigation subsequently incurred by such indemnified party in
       connection with the defense thereof. The indemnified party shall have the
       right to employ its counsel in any such action, but the fees and expenses
       of such counsel shall be at the expense of such indemnified party unless
       (i) the employment of counsel by such indemnified party has been
       authorized in writing by the indemnifying parties, (ii) the indemnified
       party shall have been advised by counsel that there may be one or more
       legal defenses available to it which are different from or in addition to
       those available to the indemnifying party (in which case the indemnifying
       parties shall not have the right to direct the defense of such action on
       behalf of the indemnified party) or (iii) the indemnifying parties shall
       not have employed counsel to assume the defense of such action within a
       reasonable time after notice of the commencement thereof, in each of
       which cases the fees and expenses of counsel shall be at the expense of
       the indemnifying parties. In no event shall the indemnifying parties be
       responsible for fees and expenses of more than one firm for all
       indemnified parties. An indemnifying party shall not be liable for any
       settlement of any action, suit, proceeding or claim effected without its
       written consent, which consent shall not be unreasonably withheld or
       delayed.

          9.     Contribution.  In order to provide for just and equitable
                 ------------
contribution in circumstances in which the indemnification provided for in
Section 8(a) or 8(b) is due in accordance with its terms but for any reason is
held to be unavailable to or insufficient to hold harmless an indemnified party
under Section 8(a) or 8(b), then each indemnifying party shall contribute to the
aggregate losses, claims, damages and liabilities (including any investigation,
legal and other expenses reasonably incurred in connection with, and any amount
paid in settlement of, any action, suit or proceeding or any claims asserted,
but after deducting any contribution received by any person entitled hereunder
to contribution from any person who may be liable for contribution) to which the
indemnified party may be subject in such proportion as is appropriate to reflect
the relative benefits received by the Company and the Selling Shareholders on
the one hand and the Underwriters on the other from the offering of the Shares
or, if such allocation is not permitted by applicable law or indemnification is
not available as a result of the indemnifying party not having received notice
as provided in Section 8 hereof, in such proportion as is appropriate to reflect
not only the relative benefits referred to above but also the relative fault of
the Company and the Selling Shareholders on the one hand and the Underwriters on
the other in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations.  The relative benefits received by the Company, the
Selling Shareholders and the Underwriters shall be deemed to be in the same
proportion as (x) the total proceeds from the offering (net of underwriting
discounts but before deducting expenses) received by the Company or the Selling
Shareholders, as set forth in the table on the cover page of the Prospectus,
bear to (y) the underwriting discounts received by the Underwriters, as set
forth in the table on the cover page of the Prospectus.  The relative fault of
the Company and the Selling Shareholders or the Underwriters shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact related to information supplied by the Company and
the Selling Shareholders or the Underwriters and the parties' relative intent,
knowledge, access

                                      -36-


to information and opportunity to correct or prevent such statement or omission.
The Company, the Selling Shareholders and the Underwriters agree that it would
not be just and equitable if contribution pursuant to this Section 9 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. Notwithstanding
the provisions of this Section 9, (i) in no case shall any Underwriter (except
as may be provided in the Agreement Among Underwriters) be liable or responsible
for any amount in excess of the underwriting discount applicable to the Shares
purchased by such Underwriter hereunder; (ii) the Company shall be liable and
responsible for any amount in excess of such underwriting discount; and (iii) in
no case shall any Selling Shareholders be liable and responsible for any amount
in excess of the aggregate net proceeds of the sale of Shares received by such
Selling Shareholders; provided, however, that no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this Section 9, each person, if
any, who controls an Underwriter within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act shall have the same rights
to contribution as such Underwriter, and each person, if any, who controls the
Company within the meaning of the Section 15 of the Securities Act or Section
20(a) of the Exchange Act, each officer of the Company who shall have signed the
Registration Statement and each director of the Company shall have the same
rights to contribution as the Company, subject in each case to clauses (i) and
(ii) in the immediately preceding sentence of this Section 9. Any party entitled
to contribution will, promptly after receipt of notice of commencement of any
action, suit or proceeding against such party in respect of which a claim for
contribution may be made against another party or parties under this Section 9,
notify such party or parties from whom contribution may be sought, but the
omission so to notify such party or parties from whom contribution may be sought
shall not relieve the party or parties from whom contribution may be sought from
any other obligation it or they may have hereunder or otherwise than under this
Section 9. No party shall be liable for contribution with respect to any action,
suit, proceeding or claim settled without its written consent. The Underwriter's
obligations to contribute pursuant to this Section 9 are several in proportion
to their respective underwriting commitments and not joint.

          10.    Termination.  This Agreement may be terminated with respect to
                 -----------
the Shares to be purchased on a Closing Date by the Representatives by notifying
the Company and the Selling Shareholders at any time:

            (a) in the absolute discretion of the Representatives at or before
       any Closing Date:  (i) if on or prior to such date, any domestic or
       international event or act or occurrence has materially disrupted, or in
       the opinion of the Representatives will in the future materially disrupt,
       the securities markets; (ii) if there has occurred any new outbreak or
       material escalation of hostilities or other calamity or crisis the effect
       of which on the financial markets of the United States or Canada is such
       as to make it, in the judgment of the Representatives, inadvisable to
       proceed with the offering; (iii) if there shall be such a material
       adverse change in general financial, political or economic conditions or
       the effect of international conditions on the financial markets

                                      -37-


       in the United States or Canada is such as to make it, in the judgment of
       the Representatives, inadvisable or impracticable to market the Shares;
       (iv) if trading in the Shares has been suspended by the Commission, the
       Ontario Securities Commission or The Toronto Stock Exchange, or trading
       generally on the New York Stock Exchange, Inc., the American Stock
       Exchange, Inc., the Nasdaq National Market or The Toronto Stock Exchange
       has been suspended or limited, or minimum or maximum ranges for prices
       for securities shall have been fixed, or maximum ranges for prices for
       securities have been required, by said exchanges or by order of the
       Commission, the National Association of Securities Dealers, Inc., or any
       other governmental or regulatory authority; (v) if a banking moratorium
       has been declared by any state or federal authority; or (vi) if, in the
       judgment of the Representatives, there has occurred since the date hereof
       a Material Adverse Effect, or

            (b) at or before any Closing Date, that any of the conditions
       specified in Section 6 shall not have been fulfilled when and as required
       by this Agreement.

          If this Agreement is terminated pursuant to any of its provisions,
neither the Company nor the Selling Shareholders shall be under any liability to
any Underwriter, and no Underwriter shall be under any liability to the Company,
except that (y) if this Agreement is terminated by the Representatives or the
Underwriters because of any failure, refusal or inability on the part of the
Company or the Selling Shareholders to comply with the terms or to fulfill any
of the conditions of this Agreement, the Company or, if applicable, the
defaulting Selling Shareholders will reimburse the Underwriters for all
reasonable out-of-pocket expenses (including the reasonable fees and
disbursements of their counsel) incurred by them in connection with the proposed
purchase and sale of the Shares or in contemplation of performing their
obligations hereunder and (z) no Underwriter who shall have failed or refused to
purchase the Shares agreed to be purchased by it under this Agreement, without
some reason sufficient hereunder to justify cancellation or termination of its
obligations under this Agreement, shall be relieved of liability to the Company,
the Selling Shareholders or to the other Underwriters for damages occasioned by
its failure or refusal.

          11.    Substitution of Underwriters.  If one or more of the
                 ----------------------------
Underwriters shall fail (other than for a reason sufficient to justify the
cancellation or termination of this Agreement under Section 10) to purchase on
any Closing Date the Shares agreed to be purchased on such Closing Date by such
Underwriter or Underwriters, the Representatives may find one or more substitute
underwriters to purchase such Shares or make such other arrangements as the
Representatives may deem advisable or one or more of the remaining Underwriters
may agree to purchase such Shares in such proportions as may be approved by the
Representatives, in each case upon the terms set forth in this Agreement.  If no
such arrangements have been made by the close of business on the business day
following such Closing Date,

            (a) if the number of Shares to be purchased by the defaulting
       Underwriters on such Closing Date shall not exceed 10% of the Shares that
       all the Underwriters are obligated to purchase on such Closing Date, then
       each of the nondefaulting

                                      -38-


       Underwriters shall be obligated to purchase such Shares on the terms
       herein set forth in proportion to their respective obligations hereunder;
       provided, that in no event shall the maximum number of Shares that any
       Underwriter has agreed to purchase pursuant to Section 1 be increased
       pursuant to this Section 11 by more than one-ninth of such number of
       Shares without the written consent of such Underwriter, or

            (b) if the number of Shares to be purchased by the defaulting
       Underwriters on such Closing Date shall exceed 10% of the Shares that all
       the Underwriters are obligated to purchase on such Closing Date, then the
       Company shall be entitled to one additional business day within which it
       may, but is not obligated to, find one or more substitute underwriters
       reasonably satisfactory to the Representatives to purchase such Shares
       upon the terms set forth in this Agreement.

          In any such case, either the Representatives or the Company shall have
the right to postpone the applicable Closing Date for a period of not more than
five business days in order that necessary changes and arrangements (including
any necessary amendments or supplements to the Registration Statement or
Prospectus) may be effected by the Representatives and the Company.  If the
number of Shares to be purchased on such Closing Date by such defaulting
Underwriter or Underwriters shall exceed 10% of the Shares that all the
Underwriters are obligated to purchase on such Closing Date, and none of the
nondefaulting Underwriters or the Company shall make arrangements pursuant to
this Section 11 within the period stated for the purchase of the Shares that the
defaulting Underwriters agreed to purchase, this Agreement shall terminate with
respect to the Shares to be purchased on such Closing Date without liability on
the part of any nondefaulting Underwriter to the Company or the Selling
Shareholders and without liability on the part of the Company, except in both
cases as provided in Sections  7(b), 8, 9 and 10.  The provisions of this
Section 11 shall not in any way affect the liability of any defaulting
Underwriter to the Company or the nondefaulting Underwriters arising out of such
default.  A substitute underwriter hereunder shall become an Underwriter for all
purposes of this Agreement.

          12.    Miscellaneous.  The respective agreements, representations,
                 -------------
warranties, indemnities and other statements of the Company or its officers, of
the Selling Shareholders and of the Underwriters set forth in or made pursuant
to this Agreement shall remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or the
Selling Shareholders or any of the officers, directors or controlling persons
referred to in Sections 8 and 9 hereof, and shall survive delivery of and
payment for the Shares.  The provisions of Sections 7(b), 8, 9 and 10 shall
survive the termination or cancellation of this Agreement.

          This Agreement has been and is made for the benefit of the
Underwriters, the Company and the Selling Shareholders and their respective
successors and assigns, and, to the extent expressed herein, for the benefit of
persons controlling any of the Underwriters, or the Company, and directors and
officers of the Company, and their respective successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement.

Needham & Company, Inc.
c/o CIBC World Markets Corp.

On behalf of the Several
Underwriters named on
Schedule I attached hereto

Ladies and Gentlemen:

     Reference is made to the Underwriting Agreement, dated April 11, 2000 (the
"Underwriting Agreement"), among GSI Lumonics Inc., a New Brunswick corporation
(the "Company"), the Selling Shareholders named therein and the several
Underwriters named in Schedule I thereto and hereto (the "Underwriters"), for
whom you are acting as Representatives (the "Representatives").  The
Underwriting Agreement provides for the purchase by the Underwriters from the
Company, subject to the terms and conditions set forth therein, of an aggregate
of 4,000,000 of the Company's common shares (the "Firm Shares") and for the
Company and the Selling Shareholders to grant to the Underwriters an option to
purchase up to an aggregate of 600,000 additional Common Shares (the "Option
Shares") from it and the Selling Shareholders as contemplated in the
Underwriting Agreement for the purposes of covering over-allotments in
connection with the sale of the Firm Shares.  This Agreement is the Price
Determination Agreement referred to in the Underwriting Agreement.

     Pursuant to second paragraph of the Underwriting Agreement, the undersigned
agree with the Representatives as follows:

     The initial public offering price per share for the Firm Shares shall be
U.S.$..

     The purchase price per share for the Firm Shares to be paid by the several
Underwriters to the Company on the Closing Date shall be U.S.$.; and the
underwriting discounts and commissions per share for the Firm Shares to be paid
by the Company to the several Underwriters on the Closing Date shall be U.S.$..
Any Option Shares shall


be sold for the same price per share and with the same underwriting discounts
and commissions per share as apply to the Firm Shares.

     The price, commission and net proceeds for the Firm Shares to be sold in
Canada will be calculated in Canadian dollars at the approximate equivalent of
the U.S. dollar amount set out above, based on the prevailing U.S. dollar
exchange rates as of the date of pricing of the Offering.

     The Company and the Selling Shareholders represent and warrant to each of
the Underwriters, and the Selling Shareholders represent and warrant to the
Company, that their representations and warranties set forth in Section 4 and
Section 5 of the Underwriting Agreement are accurate as though expressly made at
and as of the date hereof.

     As contemplated by the Underwriting Agreement, attached as Schedule I is a
completed list of the several Underwriters, which shall be a part of this
Agreement and the Underwriting Agreement.

     This agreement shall be governed by and construed in accordance with the
laws of the State of New York without regard to the conflict of laws principles
of such state.


     If the foregoing is in accordance with your understanding of the agreement
among the Underwriters, the Company and the Selling Shareholders, please sign
and return to the Company a counterpart hereof; whereupon this instrument along
with all counterparts and together with the Underwriting Agreement shall be a
binding agreement among the Underwriters, the Company and the Selling
Shareholders in accordance with its terms and the terms of the Underwriting
Agreement.

                                      Very truly yours,

                                      GSI LUMONICS INC.
