ITEM 1.           SECURITY AND ISSUER.

         This Statement on Schedule 13D (this "Schedule 13D") relates to the
common shares, no par value (the "Common Shares"), of Metrowerks Inc. (the
"Company"), a corporation incorporated under the Canada Business Corporations
Act (the "CBCA"). The principal executive offices of the Company are located at
1500 du College, Suite 300, Saint Laurent, Quebec H4L SG6, Canada.

ITEM 2.           IDENTITY AND BACKGROUND.

         (a)-(c), (f). This Schedule 13D is being filed on behalf of Motorola,
Inc., a Delaware corporation ("Motorola"), and Motorola Canada Acquisition
Corp., a corporation incorporated under the CBCA that is an indirect
wholly-owned subsidiary of Motorola ("Purchaser"). Purchaser recently was
organized for the purpose of making an offer to purchase all of the issued and
outstanding Common Shares (the "Offer") and then, subsequent to the completion
of the Offer, effecting either a compulsory acquisition (the "Compulsory
Acquisition") or other subsequent acquisition transaction (the "Amalgamation"),
as more fully described in Item 4 of this Schedule 13D. Neither the filing of
this Schedule 13D nor the information contained herein shall be deemed to
constitute an affirmation by Motorola or Purchaser that it is the beneficial
owner of the Common Shares referred to herein for purposes of Section 13(d) of
the Securities Exchange Act of 1934, as amended (the "Act"), or for any other
purpose, and such beneficial ownership is expressly disclaimed.

         Motorola's principal executive offices are located at 1303 East
Algonquin Road, Schaumburg, Illinois 60196. Motorola is a global leader in
providing integrated communications solutions and embedded electronic solutions.
These include: (i) software-enhanced wireless telephone, two-way radio,
messaging and satellite communications products and systems, as well as
networking and Internet-access products, for consumers, network operators, and
commercial, government and industrial customers; (ii) embedded semiconductor
solutions for customers in the consumer, networking and computing,
transportation and wireless communications markets; and (iii) embedded
electronic systems for automotive, communications, imaging, manufacturing
systems, computer and consumer markets.

         The names, business addresses and present principal occupations of the
directors and executive officers of Motorola are set forth in the attached
Schedule A, which is incorporated herein by reference. To the best of Motorola's
knowledge, all directors and executive officers of Motorola are citizens of the
United States.

         Purchaser's principal executive offices are located at 3900 Victoria
Park Avenue, North York, Ontario M2H 3H7, Canada. Purchaser has not carried on
any activities except in connection with the Offer and either the Compulsory
Acquisition or the Amalgamation.

         The names, business addresses, present principal occupations of the
directors and executive officers of Purchaser and the citizenship of such
persons are set forth in the attached Schedule B, which is incorporated herein
by reference.

         (d)-(e). Neither Motorola, Purchaser, nor, to the best knowledge of
Motorola or Purchaser, any of the directors or executive officers listed on
Schedule A or Schedule B respectively, has been, during the last five years, (a)
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors) or (b) a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws.

ITEM 3.           SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         The total amount of funds required by Purchaser and Motorola to
consummate the Offer and either the Compulsory Acquisition or the Amalgamation
and to pay related fees and expenses is estimated to be approximately
US$100,000,000. Purchaser will obtain all funds required by it from Motorola.
Motorola will obtain all funds required to consummate the Offer and either the
Compulsory Acquisition or the Amalgamation from working capital.


<PAGE>

ITEM 4.           PURPOSE OF TRANSACTION.

         The purpose of the Offer is to enable Purchaser to acquire the Company
by purchasing all of the issued and outstanding Common Shares.

         On August 19, 1999, Motorola and the Company entered into an agreement
(the "Offer Agreement") providing for the commencement by Motorola, through
Purchaser, of an offer to purchase all of the issued and outstanding Common
Shares at a price of US$6.25 per share. The Offer Agreement provides that,
subject to the terms and conditions contained therein, Purchaser will commence
the Offer as soon as reasonably practicable after the execution of the Offer
Agreement but not later than September 2, 1999. The Offer is being made only for
the Common Shares and not for any options, warrants or other rights to purchase
Common Shares, although the Offer does extend to Common Shares that may become
outstanding pursuant to the exercise of outstanding options to acquire Common
Shares. Treatment of unexercised employee stock options is described below. The
Offer will be made in accordance with applicable laws and will be held open for
acceptance for 21 calendar days, subject to the right of Purchaser to extend the
period during which Common Shares may be deposited.

         At the sole discretion of Motorola, the Offer may be structured to
permit holders that hold Common Shares indirectly through a holding company
incorporated under the CBCA that has no assets other than the Common Shares and
has no tax or other liabilities to deposit all of the holding company's issued
and outstanding shares ("Holdco Shares") and all Common Shares held by the
holding company to Purchaser, whereby Purchaser will purchase such Holdco Shares
in lieu of the Common Shares owned by the holding company that have been
deposited directly under the Offer. The aggregate consideration payable for the
Holdco Shares will be identical to the consideration that the holding company
would have been entitled to receive had the Common Shares owned by the holding
company been purchased directly under the Offer. If a shareholder chooses to use
this alternative, such shareholder will thereby dispose of its entire interest
in its holding company and its entire indirect interest in its Common Shares as
a result of the sale of its Holdco Shares to Purchaser, and each holding company
will become a wholly-owned subsidiary of Purchaser. A valid deposit under the
Offer of a holding company's Holdco Shares and all Common Shares held by such
holding company will constitute an acceptance of the Offer.

         The Offer is subject to certain conditions, including, among others:
(i) a minimum of not less than 77% of the outstanding Common Shares (calculated
on a fully diluted basis, but excluding Common Shares issuable pursuant to the
Option Agreement, as described below) being validly tendered pursuant to the
Offer and not withdrawn and (ii) all requisite regulatory approvals in
connection with the Offer being obtained, in each case as set forth in the Offer
Agreement.

         If within 120 days after the expiry of the Offer the Offer has been
accepted by holders of not less than 90% of all of the Common Shares (including
securities currently convertible into Common Shares), Purchaser intends to
acquire the remainder of the Common Shares, on the same terms as Common Shares
were acquired under the Offer, pursuant to the compulsory acquisition provisions
of Section 206 of the CBCA. If Purchaser takes up and pays for Common Shares
validly deposited under the Offer and the statutory right of acquisition
described above is not available, then Purchaser anticipates that it will seek
to cause a special meeting of shareholders of the Company to be called to
consider an amalgamation, or another transaction including a statutory
arrangement, involving Purchaser (or an affiliate of Purchaser) and the Company
for the purposes of enabling Purchaser to acquire all of the Common Shares not
deposited under the Offer for consideration identical to the consideration
offered under the Offer. Should any such special meeting of shareholders of the
Company be called, Motorola will vote any shares of Common Shares over which it
has voting power in favor of any such subsequent transaction.

         The Offer Agreement provides that the Company will (i) accelerate the
vesting of any outstanding unvested options issued under the Company's Amended
and Restated (#2) 1995 Stock Option Plan or any predecessor plan (the "Plan"),
subject to obtaining the consent of the holder where required under the terms of
the Plan, and (ii) upon the written direction of Motorola, take any action in
respect of the options outstanding under the Plan that is permitted under the
terms of the Plan and under all applicable laws.

         The Offer Agreement further provides that upon the take-up and payment
for Common Shares by Purchaser pursuant to the Offer, and provided Purchaser
thereby acquires at least a majority of the outstanding Common Shares, the
Company shall use its reasonable best efforts to (i) ensure that Purchaser will
have the ability to immediately replace the members of the Board of Directors of
the Company with individuals designated by Purchaser, and (ii) assist Purchaser

<PAGE>

in acquiring, pursuant to a subsequent acquisition transaction or other
transaction proposed by Purchaser, all of the Common Shares not tendered to
Purchaser.

         Concurrently with the execution of the Offer Agreement, Motorola has
entered into separate lock-up agreements, dated as of August 19, 1999 (the
"Lock-Up Agreements"), with each of Jean J. Belanger, Chairman of the Board and
Chief Executive Officer of the Company, and Gregory P. Galanos, President and
Chief Technology Officer of the Company (the "Significant Shareholders").
Pursuant to the Lock-Up Agreements, the Significant Shareholders have
irrevocably and unconditionally agreed to deposit the aggregate of 3,790,478
Common Shares presently beneficially owned by them (representing approximately
25.8% of the Common Shares issued and outstanding), any Common Shares issuable
upon the exercise of certain stock options held by the Significant Shareholders
(subject to the acceleration by the Company of the vesting of such options), and
any Common Shares subsequently obtained by the Significant Shareholders, as soon
as practicable after the execution of the Lock-Up Agreements and in any event no
later than the expiry of the Offer. Among other covenants in the Lock-Up
Agreements, the Significant Shareholders have granted to Motorola their
irrevocable proxy and attorney-in-fact to vote their Common Shares in order to
give effect to the covenants of the Significant Shareholders contained in the
Lock-Up Agreements and in furtherance of the obligations of the Company
contained in the Offer Agreement. The Significant Shareholders have further
agreed (i) to not grant or agree to grant any proxy or other right to vote the
Common Shares of the Significant Shareholders or enter into any voting trust or
other agreement with respect to the right to vote, call meetings of shareholders
or give consents or approvals of any kind as to their Common Shares, and (ii) to
exercise the voting rights attaching to the Common Shares of the Significant
Shareholders and otherwise use their best efforts to oppose any proposed action
by the Company or its shareholders in respect of any amalgamation or other
business combination or similar transaction involving the Company or which might
reasonably be regarded as being directed toward or likely to prevent or delay
the take up and payment of the Common Shares deposited under the Offer or the
successful completion of the Offer.

         Concurrently with the execution of the Offer Agreement and the Lock-Up
Agreements, and as a condition and inducement to Motorola's execution of the
Offer Agreement and completion of the Offer, Motorola and the Company have
entered into a stock option agreement, dated as of August 19, 1999 (the "Option
Agreement"), whereby the Company has granted to Motorola an unconditional,
irrevocable option (the "Option") to purchase an aggregate of 2,913,172 Common
Shares at a price per Common Share equal to US$6.25, provided that the number of
Common Shares that may be acquired by exercising the Option may not exceed 19.9%
of the issued and outstanding Common Shares at the time of the exercise (without
giving effect to the Common Shares issued or issuable under the Option).
Motorola may exercise the Option only if (i) the Offer Agreement is terminated
for reasons set out in the Offer Agreement that also require the Company to pay
Purchaser a termination fee and (ii) the exercise is made prior to (a) thirteen
months (or such longer period as provided in the Option Agreement) after
termination of the Offer Agreement, (b) the completion of the acquisition of all
of the issued and outstanding Common Shares by Motorola or Purchaser, or (c) the
payment of any amounts in connection with the repurchase of the Option in
accordance with the terms of the Option Agreement that total more than $4.7
million.

         If either the Compulsory Acquisition or the Amalgamation is completed
as planned, Motorola expects to cause the Company to (i) have the Common Shares
to cease to be listed on The Toronto Stock Exchange and the National Market
System of The Nasdaq Stock Market, Inc. and (ii) terminate the registration of
the Common Shares pursuant to Section 12(g)(4) of the Act.

         The preceding summary of certain provisions of the Offer Agreement, the
Lock-Up Agreements and the Option Agreement is not intended to be complete and
is qualified in its entirety by reference to the full text of such agreements,
copies of which are filed as Exhibits 1, 2, 3 and 4 hereto, and which are
incorporated herein by reference. Other than as described above, neither
Motorola nor Purchaser has any plans or proposals that relate to or would result
in any of the actions described in subparagraphs (a) through (j) of Item 4 of
Schedule 13D (although, subject to the provisions of the Offer Agreement,
Motorola and Purchaser reserve the right to develop such plans).

ITEM 5.           INTEREST IN SECURITIES OF THE COMPANY.

         (a) Pursuant to the Lock-Up Agreements, Motorola, indirectly, may be
deemed to be the beneficial owner of 3,790,478 Common Shares, which represent
25.8% of the total outstanding Common Shares. In addition, if the Offer
Agreement is terminated for reasons set out in the Offer Agreement that also
require the Company to pay Purchaser a termination fee, Motorola will have the
right pursuant to the Option Agreement to acquire up to an aggregate of
2,913,172 Common Shares, provided that the number of Common Shares that may be
acquired by exercising the Option may not exceed 19.9% of the issued and

<PAGE>

outstanding Common Shares at the time of the exercise (without giving effect to
the Common Shares issued or issuable under the Option). The aggregate 2,913,172
shares that Motorola has the right to acquire by exercising the Option, combined
with the 3,790,478 Common Shares subject to the Lock-Up Agreements, represent
38.2% of the total outstanding Common Shares. Neither the filing of this
Schedule 13D nor any of its contents shall be deemed to constitute an admission
that Motorola or Purchaser is the beneficial owner of the Common Shares referred
to in this paragraph for purposes of Section 13(d) of the Act or for any other
purpose, and such beneficial ownership is expressly disclaimed.

         (b) Motorola and Purchaser have the shared power to vote or to direct
the vote of 3,790,478 Common Shares. Pursuant to the Lock-Up Agreements, each
Significant Shareholder is restricted from voting its Common Shares in
accordance with the limitations summarized in Item 4 above. If Motorola
exercises the Option, it will have the sole power to vote or to direct the vote
of up to an aggregate of 2,913,172 Common Shares.

         (c) Except as set forth in this Item 5, to the best knowledge of
Motorola and Purchaser, neither Motorola, Purchaser, nor any of their respective
directors or executive officers, nor any other person described in Item 2 above
has beneficial ownership of, or has engaged in any transaction during the past
60 days in, any Common Shares.

         (d) None.

         (e) Not applicable.

ITEM 6.           CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
                  RESPECT TO SECURITIES OF THE ISSUER.

         Except as described in this Schedule 13D and as set forth in Item 7 of
this Schedule 13D, to the best knowledge of Motorola and Purchaser, there are no
other contracts, arrangements, understandings or relationships (legal or
otherwise) among the persons named in Item 2 and between such persons and any
person with respect to any securities of the Company, including but not limited
to, transfer or voting of any of the securities of the Company, joint ventures,
loan or option arrangements, puts or calls, guarantees of profits, division of
profits or loss, or the giving or withholding of proxies, or a pledge or
contingency the occurrence of which would give another person voting power or
investment power over the securities of the Company.

Metrowerks Inc.
9801 Metric Boulevard
Suite 100
Austin, Texas 78758

Attention:        Jean Belanger, Chairman of the Board

Dear Sirs:

         This letter agreement (the "Agreement") sets out the terms and
conditions upon which Motorola, Inc. (the "Purchaser") will cause a direct or
indirect wholly-owned subsidiary of the Purchaser (the "Offeror") to make an
offer (the "Offer"), on substantially the terms and conditions summarized in
Schedule "A" forming part of this Agreement, to purchase all of the issued and
outstanding common shares (including any common shares which may become
outstanding pursuant to the exercise of outstanding options to acquire common
shares) (the "Common Shares") of Metrowerks Inc. (the "Company"). The term
"Offer" shall include any amendments to, or extensions of, the Offer made in
accordance with the terms of this Agreement, including, without limitation,
removing or waiving any condition or extending the date by which Common Shares
may be deposited. The Purchaser has, concurrently with the execution of this
Agreement, entered into employment and non-competition agreements with certain
of the Company's key employees (the "Employment Agreements"), lock-up agreements
with Jean Belanger and Gregory Galanos, the Company's principal shareholders
(the "Lock-up Agreements"), and an option agreement with the Company pursuant to
which the Purchaser has been granted the option to purchase Common Shares (the
"Option Agreement"). This Agreement also sets out the terms and conditions of
the agreement by the Company, among other things, to recommend that the holders
of the Common Shares accept the Offer and not to solicit expressions of interest
for, or assist or encourage competing offers for, the Common Shares.

         All references to dollar amounts in this Agreement are to United States
dollars, unless otherwise stated.

1. COVENANTS OF THE OFFEROR. Upon execution of this Agreement, the Purchaser
will cause the Offeror:

         (a)      not later than September 2, 1999 (the "Proposed Offer Date"),
                  to make a take-over bid to purchase 100% of the Common Shares
                  issued and outstanding as of such date, on substantially the
                  terms and conditions summarized in Schedule "A" forming part
                  of this Agreement;

         (b)      subject to the satisfaction of the terms and conditions of the
                  Offer, to take-up and pay for Common Shares tendered under the
                  Offer in accordance with Canadian securities laws and United
                  States securities laws, if applicable; and

         (c)      upon the last take-up and payment of Common Shares under the
                  Offer, to proceed expeditiously with a compulsory acquisition
                  or subsequent acquisition transaction whereby holders of
                  Common Shares will receive cash consideration per Common Share
                  in a transaction which is at least as favourable to holders of
                  Common Shares as the Offer.

         The Purchaser shall cause the Offeror to mail the Offer and
accompanying take-over bid circular (such circular, together with the Offer,
being referred to herein as the "Bid Circular") in accordance with applicable
laws to each holder of Common Shares (a "Shareholder") as soon as reasonably
practicable and not later than 11:59 p.m. (Toronto time) on September 2, 1999
(such time on such date being referred to herein as the "Latest Mailing Time");
provided, however, that if the mailing of the Offer is delayed by (i) an
injunction or order made by a court or regulatory authority of competent
jurisdiction or (ii) the Offeror not having obtained any regulatory waiver,
consent or approval which is necessary to permit it to mail the Offer or take up


<PAGE>


                                      - 3 -


and pay for the Common Shares tendered under the Offer, then, provided that such
injunction or order is being contested or appealed or such regulatory waiver,
consent or approval is being actively sought, as applicable, the Latest Mailing
Time shall be extended for a period ending on the fifth business day following
the date on which such injunction or order ceases to be in effect or such
waiver, consent or approval is obtained, as applicable, provided however that if
such event has not occurred by September 30, 1999, this Agreement will
terminate.

         The Offer will be made in accordance with applicable laws and shall be
open for acceptance for a period of 21 calendar days, subject to the right of
the Offeror to extend the period during which Common Shares may be deposited
under the Offer (the "Expiry Time"). The Purchaser shall cause the Offeror to
use all reasonable efforts to consummate the Offer, subject to the terms and
conditions hereof and thereof.

         At the sole discretion of the Purchaser, the Offer may be structured so
as to permit Shareholders who hold Common Shares indirectly through a holding
company incorporated under the Canada Business Corporation Act and meeting the
requirements described below (a "Holdco") to deposit all of the issued and
outstanding shares of such Holdco (the "Holdco Shares") and all Common Shares
held by such Holdco to the Offer (the "Holdco Alternative"), and the Offeror
will purchase the Holdco Shares in lieu of the Common Shares owned by such
Holdco that have been deposited directly under the Offer. The aggregate
consideration payable for the Holdco Shares would be identical to that which the
Holdco would have been entitled to receive had the Common Shares owned by such
Holdco been purchased directly under the Offer. If a Shareholder chooses to use
the Holdco Alternative, such Shareholder would thereby dispose of its entire
direct interest in its Holdco and its entire indirect interest in its Common
Shares as a result of the sale of its Holdco Shares to the Offeror, and each
Holdco would become a wholly-owned subsidiary of the Offeror. A valid deposit of
Holdco Shares and all Common Shares held by such Holdco under the Offer would
constitute an acceptance of the Offer.



<PAGE>


                                      - 4 -


          If the Holdco Alternative is made available by the Purchaser, a
Shareholder wishing to utilize the Holdco Alternative must first advise the
Offeror of such intention, in writing, at least seven days prior to the Expiry
Time and must enter into a share purchase agreement (a "Holdco Share Purchase
Agreement") with the Offeror in which such Shareholder shall provide the Offeror
with representations, warranties and covenants: (i) to the effect that the
Holdco will have no assets other than the Common Shares and no tax or other
liabilities; (ii) as to the due incorporation of the Holdco and its corporate
authority; (iii) as to the ownership of the outstanding shares of the Holdco and
the Common Shares held by the Holdco; (iv) that the Holdco has never carried on
any business or operations of any kind; (v) that the Holdco has not declared any
dividends or other distributions which would represent a liability on the part
of the Holdco to its shareholders; (vi) as to the paid up capital of each class
and series of shares of the Holdco; (vii) as to the adjusted cost base of the
Common Shares to the Holdco; and (viii) as to such other matters as the Offeror
may reasonably require. The Holdco Share Purchase Agreement shall also provide
that the Shareholders shall indemnify the Offeror against any and all
liabilities of the Holdco (including liabilities arising prior to or as a result
of the sale of the Holdco Shares to the Offeror), and with an opinion of counsel
addressing such matters as are customary in a share purchase transaction. The
Offeror may also require a Shareholder wishing to utilize the Holdco Alterative
to provide it with any such legal opinions, or to obtain any such approvals,
authorizations or income tax rulings, as the Offeror considers reasonably
necessary to provide assurance that the Holdco does not have, and will not have
as a result of the sale of the Holdco Shares to the Offeror, any tax or other
liabilities.

         The Purchaser will use its reasonable efforts to determine whether the
Holdco Alternative can be made available on a basis which is without tax or
other legal risk to the Purchaser and the Offeror.

2. CONDITIONS PRECEDENT TO THE OBLIGATIONS OF THE PURCHASER. Notwithstanding the
foregoing, the obligations of the Purchaser to cause the Offeror to make the
Offer shall be subject to the satisfaction, on the Proposed Offer Date (or any
earlier date on which the Offeror proposes to make the Offer or on any later





<PAGE>


                                      - 5 -

date on which the Offer is required to be made pursuant to Section 1 hereof), of
each of the following conditions precedent:

         (i)      each of the conditions set forth in paragraphs (d) through (h)
                  of section 4 of Schedule "A" hereto shall have been satisfied;
                  and

         (ii)     each of the Specified Representations and Warranties shall be
                  true and correct in all respects, each of the other
                  representations and warranties set forth in this Agreement
                  shall be true and correct in all material respects, and the
                  Company shall have performed in all respects any covenant or
                  complied in all respects with any agreement to be performed by
                  it under this Agreement prior to such date.

         The Company shall deliver to the Purchaser and the Offeror, prior to
the making of the Offer by the Offeror on the Proposed Offer Date (or any
earlier date on which the Offeror proposes to make the Offer or on any later
date on which the Offer is required to be made pursuant to Section 1 hereof), a
certificate of a senior officer of the Company confirming the matters set forth
in paragraphs (i) and (ii) above.

         The foregoing conditions precedent are for the sole benefit of the
Purchaser and may be waived by the Purchaser in whole or in part at any time or
from time to time.

3. DIRECTORS' CIRCULAR. The Company hereby approves of and consents to the Offer
and to the inclusion in the Bid Circular of reference to the determinations,
approvals and recommendations of the Company's board of directors (the "Board")
and of Broadview International referred to in Sections 5(ee) and (ff) hereof.
The Company agrees to prepare and file in accordance with all applicable laws
and make available for mailing, concurrently and together with the Bid Circular,
sufficient copies of a directors' circular meeting the requirements of Canadian
securities laws, in both the English and French languages as circumstances may
require, and a Schedule 14D-9F meeting the requirements of U.S. securities laws




<PAGE>


                                      - 6 -

relating to the Offer (collectively, the "Directors' Circular"). Prior to the
final approval of the Directors' Circular by the Board, the Company shall
provide the Purchaser with a reasonable opportunity to review and comment on the
form of the Directors' Circular, the Purchaser recognizing that whether any such
comments are appropriate will be determined by the Board, acting reasonably. The
Company agrees to provide the Purchaser and its counsel in writing with any
comments that the Company receives from the applicable securities regulatory
authorities in Canada or the U.S. on the Directors' Circular or in connection
with the Offer. The Directors' Circular and all information supplied by the
Company for inclusion in the Bid Circular and any amendments or supplements
thereto, at the time filed with applicable securities regulatory authorities or
first published, sent or given to Shareholders, as the case may be, shall not
contain any misrepresentation (as defined in the Securities Act (Ontario)) or
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, in the light of the circumstances under which they were made, not
misleading.

4. COVENANTS OF THE COMPANY. The Company hereby covenants that from the date
hereof until the earlier of: (i) the Offeror having caused the boards of
directors of the Company and each of its subsidiaries to consist of persons
designated or selected by the Purchaser or having abandoned the Offer; or (ii)
this Agreement having been terminated pursuant to Section 11 hereof:

         (a)      The Company shall operate the business and affairs of the

                  "Confidentiality Agreement") shall continue in full force and
                  effect, save and except for paragraph 1 thereof.

                  the valuation (i) required to enable the Offeror to cause the
                  Company to transfer the shares of Metrowerks Corporation (the
                  Company's United States subsidiary) to the Purchaser on a tax
                  free basis pursuant to Section 88(1) of the Income Tax Act
                  (Canada) immediately following the successful completion of
                  the Offer and (ii) of the Owned Intellectual Property (as
                  hereinafter defined).

         (e)      The Company will (i) accelerate the vesting of any outstanding
                  unvested option issued under the Company's Amended and
                  Restated (#2) 1995 Stock Option Plan or any predecessor plan
                  (the "Plan"), subject to obtaining the consent of the holder
                  where required under the terms of the Plan; and (ii) upon the
                  written direction of the Purchaser, take any action in respect
                  of the options outstanding under the Plan that is permitted
                  under the terms of the Plan and under all applicable laws.

         (f)      The Company agrees to use its reasonable best efforts to
                  co-operate with the Offeror in structuring a transaction or
                  carrying out any necessary reorganization immediately prior to
                  the completion of the Offer that is beneficial to the Offeror
                  and not detrimental to the Shareholders, provided such
                  transaction or reorganization shall not delay the completion
                  of the Offer.

         (g)      Upon the take-up and payment for Common Shares by the Offeror
                  pursuant to the Offer, and provided the Offeror thereby
                  acquires at least a majority of the outstanding Common Shares,
                  the Company shall use its reasonable best efforts to (i)
                  ensure that the Offeror will have the ability to immediately
                  replace the members of the Board with individuals designated
                  by the Offeror, and (ii) assist the Offeror in acquiring
                  pursuant to a subsequent acquisition transaction, or other
                  transaction proposed by the Offeror, all of the Common Shares
                  not tendered to the Offer.

         (h)      The Company agrees to use its reasonable best efforts to
                  preserve intact the goodwill and present relationships of the
                  Corporation and its subsidiaries with the Employees (as
                  hereinafter defined) and with customers, suppliers and other
                  persons with whom the Company and its subsidiaries have
                  business relationships, and to ensure that such relationships
                  are maintained following the completion of the Offer, and the
                  Company shall advise the Purchaser forthwith if it has reason
                  to believe that any such relationship will not continue after
                  the completion of the Offer in substantially the same manner
                  as prior to the date of this Agreement.

         (i)      The Company and its subsidiaries will consult on an ongoing
                  basis with representatives of the Purchaser to report on
                  operational matters and as to the general status of the
                  business, and in order that the representatives of the
                  Purchaser will become more familiar with the philosophy and
                  techniques of the Company and its subsidiaries, as well as
                  with their business and financial affairs, and in order to
                  provide experience as a basis for ongoing relationships in
                  connection with the acquisition of the Company by the
                  Purchaser.

         (j)      In furtherance of the transactions contemplated by this
                  Agreement and the Lock-up Agreements, the Company hereby
                  covenants and agrees to direct its transfer agent to place a
                  stop transfer order on the Common Shares held by Jean Belanger
                  and Gregory Galanos and not to amend, terminate or waive any
                  of the terms of such stop transfer order (other than to permit
                  the transfer of such Common Shares to the Offeror) during the
                  term of this Agreement.

         Nothing contained in this Agreement shall give to the Purchaser or the
Offeror, directly or indirectly, rights to control or direct the Company's
operations prior to the completion of the Offer. Prior to the completion of the

Offer, the Company shall exercise, consistent with the terms and conditions of

                           validly existing under the laws of Canada and has all
                           requisite corporate power and authority to own, lease

                           corporate power and authority to own, lease and
                           operate its properties and to carry on its business
                           as now being conducted.

                  (iii)    All of the outstanding shares of the subsidiaries of
                           the Company are validly issued, fully paid and
                           non-assessable and all such shares are owned directly
                           or indirectly by the Company, free and clear of all
                           liens, claims or encumbrances and there are no
                           outstanding options, rights, entitlements,
                           understandings, subscriptions, warrants rights,

                           transfer or ownership thereof, or commitments
                           (pre-emptive, contingent or otherwise) regarding the
                           right to acquire any such shares or other right with

                           respect to any shares of or in any of its
                           subsidiaries. The Company has disclosed the names and
                           jurisdictions of incorporation of each of its
                           subsidiaries in the Disclosure Letter. Other than
                           such subsidiaries, the Company does not have any
                           ownership interest in any other person or entity.

                  (iv)     The Company and each of its subsidiaries is duly
                           registered, licensed or otherwise qualified as a
                           foreign or extra-provincial corporation to carry on
                           business and is in good standing in each jurisdiction
                           where the character of the properties owned, leased
                           or operated by it or the nature of its activities
                           makes such registration, licence or qualification
                           necessary (except where the failure to be so
                           registered, licensed or otherwise qualified could not
                           reasonably be expected to have, individually or in
                           the aggregate, a Material Adverse Effect).

         (b)      Authority. The Company has all requisite corporate power and
                  authority to enter into this Agreement and to carry out the
                  transactions contemplated hereby. The execution and delivery
                  of this Agreement and the consummation of the transactions
                  contemplated hereby have been duly and validly authorized by
                  all necessary corporate action on the part of the Company and
                  no other corporate proceedings on the part of the Company are
                  necessary to authorize this Agreement. This Agreement has been
                  duly executed and delivered by the Company and constitutes a
                  legal, valid and binding agreement enforceable by the
                  Purchaser against the Company in accordance with its terms,
                  subject, however, to the usual limitations with respect to
                  enforcement imposed by law in connection with bankruptcy or
                  similar proceedings and the availability of equitable
                  remedies. No approval, authorization, registration, consent or
                  order or other action of or filing with any person, including
                  any court, administrative agency or other governmental

                  Agreement and the documents to be delivered hereunder or the
                  consummation by the Company of the transactions contemplated
                  hereby or thereby.

         (c)      Articles of Incorporation and By-laws. The Company has
                  furnished to the Purchaser a complete and correct copy of the
                  Articles of Amalgamation and the by-laws of the Company and
                  the equivalent charter or organizational documents of each of
                  the Company's subsidiaries. Such documents are in full force
                  and effect and no other organizational documents are
                  applicable to or binding upon the Company or any of its
                  subsidiaries. Neither the Company nor any of its subsidiaries
                  is in violation of any of the provisions of its charter or
                  organizational documents.

         (d)      No Conflict. Neither the execution and delivery of this
                  Agreement nor the consummation of the transactions
                  contemplated hereby nor compliance with any of the provisions
                  hereof will (i) conflict with or result in any breach of any
                  provision of the Company's or any of its subsidiaries'
                  Articles of Incorporation or Amalgamation, as the case may be,
                  or By-laws, (ii) result in a violation or breach of, or
                  constitute (with or without due notice or lapse of time or
                  both) a default (or give rise to any right of termination,
                  cancellation or acceleration) under, any of the terms,
                  conditions or provisions of any material note, bond, mortgage,
                  indenture, license, lease, contract, agreement or other
                  instrument or obligation to which the Company or any of its
                  subsidiaries is a party or by which any of them or any of
                  their properties or assets may be bound, or (iii) violate any
                  law, order, writ, injunction, decree, statute, rule or
                  regulation applicable to the Company or any of its
                  subsidiaries or any of their properties or assets (except in
                  the case of (iii) for such violations that could not
                  reasonably be expected to, in the aggregate, constitute a
                  Material Adverse Effect).

                  Company or any subsidiary. All of the outstanding Common
                  Shares have been duly authorized and are validly issued and
                  outstanding as fully paid and non-assessable shares, free of
                  pre-emptive rights. There are no outstanding bonds, debentures
                  or other evidences of indebtedness of the Company or any
                  subsidiary having the right to vote (or that are convertible
                  for or exercisable into securities having the right to vote)
                  with the holders of the Common Shares on any matter. There are
                  no outstanding contractual obligations of the Company or any
                  of its subsidiaries to repurchase, redeem or otherwise acquire

                  securities or with respect to the voting or disposition of any
                  outstanding securities of any of its subsidiaries. No holder
                  of securities issued by the Company has any right to compel
                  the Company to register or otherwise qualify such securities
                  for public sale in Canada or the United States. The Disclosure
                  Letter describes the capitalization of each of the
                  subsidiaries of the Company including, among other things, the
                  authorized and issued capital of such subsidiaries and the
                  names of each of the registered and beneficial holders of
                  securities of such subsidiaries and the number of securities
                  held by such Persons.

         (f)      U.S. Holders. As of April 30, 1999 and July 31, 1999, less
                  than 40% of the outstanding Common Shares were held by "U.S.
                  holders" (as such term is defined for the purposes of Schedule
                  14D-1F under the U.S. Securities Exchange Act of 1934, as
                  amended (the "Exchange Act")). For the twelve calendar month
                  periods ended April 30, 1999 and July 31, 1999, the aggregate
                  trading volume of the Common Shares on national securities
                  exchanges in the United States and on the NASDAQ National
                  Market ("NASDAQ") did not exceed the aggregate trading volume
                  of the Common Shares on securities exchanges in Canada and on
                  the Canadian Dealing Network, Inc. ("CDN") (based on volume
                  figures published by such exchanges, NASDAQ and CDN). The most
                  recent annual report and annual information form filed by the
                  Company with applicable Canadian securities regulatory
                  authorities or with the United States Securities Exchange
                  Commission do not indicate that U.S. holders hold 40% or more
                  of the outstanding Common Shares. The Company is a "foreign
                  private issuer" within the meaning of Rule 3b-4 promulgated
                  under the Exchange Act and Rule 405 of the Securities Act of
                  1933 and is not an "Investment Company" as defined under the
                  United States Investment Company Act of 1940, as amended.

         (g)      Reports. The Company has complied with its obligation to file

                  required to be filed by it with securities regulators under
                  applicable Canadian and U.S. securities laws. Each of such

                  documents or exhibits included or incorporated by reference
                  therein) (collectively, the "Reports") complied with all
                  applicable requirements of law as in effect on the date so
                  filed. None of the Reports, at the time filed, contained any
                  untrue statement of a material fact or omitted to state a
                  material fact required to be stated therein or necessary in
                  order to make the statements therein, in light of the
                  circumstances under which they were made, not misleading. The
                  Company has not filed any confidential material change report
                  with any securities authority or regulator or any stock
                  exchange or other self-regulatory authority which at the date
                  hereof remains confidential. The Company has publicly
                  disclosed in the Reports any information regarding any event,
                  circumstance or action taken or failed to be taken by the
                  Company or its subsidiaries which could individually or in the
                  aggregate reasonably be expected to have a Material Adverse
                  Effect. The Disclosure Letter sets forth a complete list of
                  all Reports filed since July 31, 1998.

         (h)      Financial Statements. The consolidated financial statements of
                  the Company as of and for the year ended July 31, 1998, and
                  for the three quarters ended April 30, 1999, all as contained
                  in the Reports (collectively, the "Company Financial
                  Statements"), were prepared in accordance with United States
                  generally accepted accounting principles applied on a
                  consistent basis throughout the periods involved (except as
                  otherwise stated in such financial statements) and present
                  fairly the consolidated financial position and results of
                  operations of the Company and its subsidiaries for the periods
                  and as of the dates thereof (subject, in the case of unaudited
                  statements, to normal, recurring year-end adjustments) and
                  reflect appropriate and adequate reserves in respect of
                  contingent liabilities, if any, of the Company and its
                  subsidiaries on a consolidated basis. There has been no change

         (r)      Tax Matters.

                  (i)      The Company and each of its subsidiaries have timely
                           filed, or caused to be filed, all Tax Returns
                           required to be filed by them (all of which returns
                           were correct and complete) and have paid, or caused
                           to be paid, all Taxes that are due and payable and
                           the Company has provided adequate accruals in
                           accordance with United States generally accepted
                           accounting principles in its most recently published
                           financial statements for any Taxes for the period
                           covered by such financial statements that have not
                           been paid, whether or not shown as being due on any
                           Tax Returns. The Company and each of its subsidiaries
                           have made adequate provision in their respective
                           books and records for any Taxes accruing in respect
                           of any period subsequent to the period covered by
                           such financial statements. Since such publication
                           date, no Tax liability not reflected in such
                           statements or otherwise provided for has been
                           assessed, proposed to be assessed, incurred or
                           accrued other than in the ordinary course of
                           business. The Company and its subsidiaries have
                           withheld from all payments made by them, or otherwise
                           collected, all amounts in respect of Taxes required
                           to be withheld therefrom or collected by them, and
                           have remitted same to the applicable Governmental
                           Entity within the required time periods. Neither the
                           Company nor any of its subsidiaries has any liability
                           for the Taxes of any other Person.

                  (ii)     Neither the Company nor any of its subsidiaries has
                           received any written notification that any issues
                           have been raised (and are currently pending) by
                           Revenue Canada, the United States Internal Revenue
                           Service or any other taxing authority, including,

                           without limitation, any sales Tax authority, in
                           connection with any of the Tax Returns referred to
                           above, and, no waivers of statutes of limitations or
                           extensions of time have been given or requested with
                           respect to the Company or any of its subsidiaries.
                           Neither the Company nor any of its subsidiaries is a
                           party to any agreement providing for the allocation
                           or sharing of Taxes with any entity that is not a
                           direct, wholly-owned subsidiary of the Company. All
                           Tax liability of the Company and its subsidiaries has
                           been assessed for all fiscal years up to and
                           including the fiscal year ended July 31, 1998. There
                           are no proposed (but unassessed) additional Taxes and
                           none has been asserted. No Tax liens have been filed
                           other than for Taxes not yet due and payable.

                  (iii)    No claim has ever been made by an authority in any
                           jurisdiction where the Company or any of its
                           subsidiaries does not file Tax Returns that the
                           Company or any of its subsidiaries is or may be
                           subject to taxation by that jurisdiction. There are
                           no liens or encumbrances on any of the assets of the
                           Company or any of its subsidiaries that arose in
                           connection with any failure (or alleged failure) to
                           pay any Tax.

                  (iv)     Each of the Company and its subsidiaries has
                           disclosed on its U.S. federal income Tax Returns all
                           positions taken therein that could give rise to a
                           substantial understatement of U.S. federal income Tax
                           within the meaning of U.S. Code Section 6662.

                  (v)      There are no outstanding rulings of, or requests for
                           rulings with, any Tax authority expressly addressed
                           to either the Company or any of its subsidiaries that
                           are, or if issued would be, binding upon the Company
                           or any of its subsidiaries.

                           currently are the subject of an audit. The Company
                           has delivered to the Purchaser correct and complete
                           copies of all income Tax Returns, examination
                           reports, and statements of deficiencies assessed
                           against or agreed to by any of the Company and its
                           subsidiaries for any Tax year which may be subject to
                           reassessment by any Tax authority.

                  (vii)    Neither the Company nor any of its subsidiaries has
                           made any payments, is obligated to make any payments,
                           or is a party to any agreement that under certain
                           circumstances could obligate it to make any payments
                           that will not be deductible under U.S. Code Sections
                           162(m) or 280G (or any similar provisions of state,
                           local or foreign law).

                  Company or any of its subsidiaries as currently conducted.

         (bb)     Representations Complete. None of the representations or
                  warranties made by the Company herein or in the Disclosure
                  Letter, when such documents are read together in their
                  entirety, contains any untrue statement of a fact, or omits to
                  state any fact necessary in order to make the statements
                  contained herein or therein, in the light of the circumstances
                  under which made, not misleading.

         (cc)     No Defaults. Neither the Company nor any of its subsidiaries
                  is in default under, and there exists no event, condition or

                  constitute such a default under any contract, agreement,
                  license or franchise to which it is a party.

         (dd)     Year 2000 Compliance. None of the systems of the Company
                  (including, without limitation, telecommunications, automation
                  and computer related systems of the Company), assets or

                  software (including embedded software) and hardware owned or
                  licensed by the Company or its subsidiaries or used by any of
                  them) has or will have any Year 2000 Error (as hereinafter
                  defined). For the purposes hereof, "Year 2000 Error" means (a)
                  any failure of computer hardware or software products or
                  technology properly to record, store, process, calculate or
                  present calendar dates falling on and after (and if
                  applicable, spans of time including) December 31, 1999 as a
                  result of the occurrence, or use of data consisting of, such
                  dates; (b) any failure of computer hardware or software
                  products or technology to calculate any information dependent
                  on or relating to dates on or after December 31, 1999 in the
                  same manner, and with the same functionality, data integrity
                  and performance, as such computer hardware or software

                  and presents calendar dates on or before December 31, 1999, or
                  information dependent on or relating to such dates; or (c) any
                  loss of functionality or performance with respect to the
                  introduction of records or processing of data containing dates
                  falling on or after December 31, 1999, and for greater
                  certainty, Year 2000 Error shall not include any failure in
                  the performance of any applications created by authorized
                  licensees of the Company's products.

         (ee)     Recommendation of the Offer. The Board, after consultation
                  with its advisers and after receiving the report of the
                  independent committee of the Board, by a resolution of Board,
                  has unanimously (i) determined that the Offer is fair to the
                  Shareholders from a financial point of view and that this
                  Agreement and the transactions contemplated hereby are in the
                  best interests of the Company and the Shareholders, (ii)
                  approved this Agreement and the transactions contemplated
                  hereby, and (iii) resolved to recommend that the Shareholders
                  accept and tender their Common Shares to the Offer, subject to
                  Section 7 of this Agreement and compliance with Section 11 of
                  this Agreement, if applicable.

         (ff)     Fairness Opinion. The Company has received an opinion of its
                  financial advisor, Broadview International, to the effect
                  that, in the context of the transactions contemplated by this
                  Agreement, the Offer is fair to the Shareholders from a
                  financial point of view. Broadview International has
                  authorized the Company to permit references to such fairness
                  opinion to be included in the Bid Circular.

         (gg)     Support of Directors. Each of the directors of the Company has
                  advised the Company that he or she intends to tender his or

         (hh)     Consents and Approval. No governmental or regulatory
                  authorization, approval, order, consent or filing is required
                  on the part of any of the Company, the Purchaser or the
                  Offeror, and no consent, approval or authorization of any
                  other party is required in connection with the Offer and the
                  completion of the transactions contemplated hereby.

         (ii)     Title to Assets. The Company and each of its subsidiaries has
                  good title to all of its leasehold interests and other
                  properties as reflected in the most recent balance sheet
                  included in the Company Financial Statements, except for such
                  properties and assets that have been disposed of in the
                  ordinary course of business since the date of such balance
                  sheet, free and clear of all mortgages, liens, pledges,
                  charges or encumbrances of any nature whatsoever, except (i)
                  the lien for current Taxes, payments of which are not yet
                  delinquent, or (ii) such imperfections in title and easements
                  and encumbrances, if any, as are not substantial in character,
                  amount or extent and do not detract from the value or
                  interfere with the present use of the property subject thereto
                  or affected thereby, or otherwise impair the Company's
                  business operations (in the manner presently carried on by the
                  Company). All leases under which the Company leases any real
                  or personal property are in good standing, valid and effective
                  in accordance with their respective terms, and there is not,
                  under any such leases, any existing default or event which
                  with notice or lapse of time or both could become a default.

         (jj)     Employment Agreements. Each of the Employment Agreements is in
                  full force and effect and is enforceable in accordance with
                  its terms against the Employee which is a party thereto,
                  except as such enforceability may be limited by principles of
                  public policy and subject to laws relating to bankruptcy,
                  insolvency and the relief of debtors and to rules of law
                  governing specific performance, injunctive relief and other

                                     - 49 -

                  equitable remedies, and there has been no amendment to or
                  breach of any such Employment Agreements.

6. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER. The Purchaser represents and
warrants to the Company as follows:

         (a)      Organization. The Purchaser is, and the Offeror will be at the
                  date of the Offer, a corporation duly organized and validly
                  existing under the laws of its jurisdiction of incorporation.

         (b)      Authority. The Purchaser has all requisite corporate power and
                  authority to enter into this Agreement, and the Offeror will
                  have at the date of the Offer all necessary corporate power
                  and authority to make the Offer and to carry out the
                  transactions contemplated hereby and by the Offer. The
                  execution and delivery of this Agreement and the consummation
                  of the transactions contemplated hereby have been duly and
                  validly authorized by all necessary corporate action on the
                  part of the Purchaser, and no other corporate proceedings on
                  the part of the Purchaser are necessary to authorize this
                  Agreement. The Agreement has been duly executed and delivered
                  by the Purchaser and constitutes a legal, valid and binding
                  agreement enforceable by the Company against the Purchaser in
                  accordance with its terms, subject, however, to the usual
                  limitations with respect to enforcement imposed by law in
                  connection with bankruptcy or similar proceedings and the
                  availability of equitable remedies.

         (c)      No Conflict. Neither the execution and delivery of this
                  Agreement nor the consummation of the transactions
                  contemplated hereby nor compliance with any of the provisions
                  hereof will (i) conflict with or result in any breach of any
                  provision of the constating documents of the Purchaser or the
                  Offeror, as the case may be, (ii) result in a violation or
                  breach of, or constitute (with or without due notice or lapse

                                     - 50 -

                  of time or both) a default (or give rise to any right of
                  termination cancellation or acceleration) under, any of the
                  terms, conditions or provisions of any note, bond, mortgage,
                  indenture, license, lease, contract, agreement or other
                  instrument or obligation to which the Purchaser or any of its
                  subsidiaries is a party or by which any of them or any of
                  their properties or assets may be bound, other than such
                  violations, breaches or defaults that shall have been waived,
                  cured or otherwise consented to in accordance with the terms
                  of such agreements or instruments or (iii) to the best of its
                  knowledge, violate any order, writ, injunction, decree,
                  statute, rule or regulation applicable to the Purchaser or any
                  of its subsidiaries or any of their properties or assets,
                  except in the case of (ii) and (iii) for violations, breaches
                  or defaults that could not reasonably be expected to, in the
                  aggregate, materially and adversely affect the Purchaser and
                  its subsidiaries taken as a whole.

         (d)      Financing. The Offeror has entered into adequate arrangements
                  sufficient to ensure, upon satisfaction of the conditions of
                  the Offer, that the required funds are available to effect the
                  full payment by the Offeror of the cash consideration payable
                  pursuant to the Offer.

         (e)      Lock-up Agreements. The Purchaser has executed and delivered
                  the Lock-up Agreements and has not entered into any other
                  agreements with Jean Belanger or Gregory Galanos in respect of
                  the Offer.

7.       EXCLUSIVITY.

         (a)      Neither the Company nor any of its subsidiaries shall, or
                  shall authorize or permit any of its respective officers,
                  directors or employees or any investment banker, financial
                  adviser, lawyer, accountant or other representative retained
                  by it to, without the Purchaser's prior written consent,
                  encourage, entertain, solicit or initiate any inquiries,



<PAGE>


                                     - 51 -

                  proposals or offers from, entertain, engage in or participate
                  in any discussions or negotiations with, or provide any
                  information to, any person or entity (or group thereof) in
                  connection with or for the purpose of soliciting a competing
                  offer or transaction, an alternate proposal, indication of
                  interest or letter of intent with respect to (i) an offer for
                  or the acquisition of any shares of the Company, (ii) the sale
                  of all or any portion of the assets of the Company or its
                  subsidiaries other than in the ordinary course of business,
                  (iii) any amalgamation, merger or other business combination
                  involving the Company or its subsidiaries, (iv) any
                  reorganization, recapitalization, liquidation or winding-up of
                  or similar transaction involving the Company or any of its
                  subsidiaries, or (v) any similar transaction which would
                  accomplish the objectives to be achieved pursuant to any of
                  the transactions described in clauses (i), (ii), (iii) or (iv)
                  above or which would prevent the successful completion of the
                  Offer (an "Acquisition Proposal"). Without limiting the
                  generality of the foregoing, the Company shall immediately
                  cease discussions with any Person other than the Purchaser
                  regarding an Acquisition Proposal, close any data room which
                  it has established, cease to provide any access whatsoever to
                  any third party to any non-public information (whether or not
                  in writing) of the Company (other than access provided
                  pursuant to a continuing legal obligation of the Company
                  entered into prior to the date hereof), terminate any
                  confidentiality or other agreement with any such third party
                  under which it has agreed to provide access to such non-public
                  information and arrange for the return of all non-public
                  information provided to any such third party, and shall not,
                  following the execution of this Agreement, enter into any
                  discussions or confidentiality or other agreement with any
                  third party under which it agrees to provide access to
                  non-public information of the Company.

         (b)      For the purposes hereof, "Superior Proposal" means an
                  Acquisition Proposal that has not been solicited, initiated,
                  assisted or encouraged (except as expressly permitted by the
                  terms of this Agreement) by or on behalf of the Company or by
                  any adviser to or director, officer, employee, investment



<PAGE>


                                     - 52 -

                  banker, financial adviser, lawyer, accountant or other
                  representative of the Company or any affiliate or associate
                  thereof, made to the Company in writing and duly authorized by
                  the board of directors of the Person making such Acquisition
                  Proposal (i) to purchase or otherwise acquire all of the
                  Common Shares, (ii) that provides for a cash consideration per
                  Common Share that exceeds the cash consideration offered by
                  the Offeror pursuant to the Offer, (iii) that is made or
                  proposed to be made by means of a take-over bid, amalgamation
                  or plan of arrangement and is available to all holders of
                  Common Shares, (iv) with conditions no more beneficial, taken
                  as a whole, to the Person making the offer than those
                  contained in the Offer for the benefit of the Offeror, and (v)
                  which the Board determines to be more favourable to the
                  Shareholders from a financial point of view than the Offer and
                  which it intends to recommend to the Shareholders.

         (c)      Subject to compliance with the terms of this Agreement,
                  nothing contained in Section 7(a) shall prevent the Board from
                  considering, negotiating, approving, recommending to the
                  Shareholders or entering into an agreement in respect of an
                  unsolicited bona fide Acquisition Proposal where the Board
                  determines in good faith, after consultation with its
                  financial advisor and after receiving written opinion of
                  outside counsel, that such Acquisition Proposal is a Superior
                  Proposal and that the taking of such action is required in the
                  proper exercise of its fiduciary duties. The Company shall
                  immediately inform the Purchaser orally and in writing of, and
                  immediately provide the Purchaser with, full details and
                  complete copies of and any other information regarding any
                  Superior Proposal, and with all details and information
                  relating to any approach to the Company or any proposal
                  (whether or not in writing) made to the Company which could
                  give rise to a Superior Proposal.

                  fails to make, or modifies, supplements or amends in a manner

                  provided that such right of termination may be exercised by
                  the Company only if after giving written notice to the
                  Purchaser of the terms of such Superior Proposal, the
                  Purchaser has not within a period of five business days
                  following receipt of such notice, agreed to increase the cash
                  consideration payable pursuant to the Offer to an amount at

                  Superior Proposal and the Company shall not enter into any
                  agreement in respect of a Superior Proposal until the

                  been complied with or (B) the Purchaser is in breach of or in
                  default under any material obligation contained in this
                  Agreement or any of the representations and warranties of the
                  Purchaser set forth in Section 6 hereof is inaccurate or
                  untrue in any material respect. Notwithstanding anything to
                  the contrary in this Section 11(a), the termination of this

                                     - 55 -

                  Agreement shall not affect any right any party has with
                  respect to the breach of this Agreement by the other party
                  prior to the termination of this Agreement.

         (b)      In the event that (i) this Agreement is terminated by the
                  Purchaser pursuant to Section 11(a)(i), or this Agreement is
                  terminated by the Company under Section 11(a)(ii)(A), then the
                  Company shall immediately, and in the case of a termination by
                  the Company prior to such termination, pay to the Offeror a
                  termination fee equal to $4,700,000. Any termination of this
                  Agreement by the Company shall not be effective unless and
                  until such termination fee has been paid.

         (c)      This Agreement may be terminated by the Purchaser or by the
                  Company if any court of competent jurisdiction or other
                  governmental body located or having jurisdiction within
                  Canada, the United States or any country or economic region in
                  which either the Company or the Purchaser, directly or
                  indirectly, has material assets or operations, shall have
                  issued a final order, decree or ruling or taken any other
                  final action restraining, enjoining or otherwise prohibiting
                  the Offer and such order, decree, ruling or other action is or
                  shall have become final and nonappealable; provided that such
                  right of termination shall not be available to any party if
                  such party shall have failed to make reasonable efforts to
                  prevent or contest the imposition of such injunction or action
                  and such failure materially contributed to such imposition.

         (d)      In the case of any termination of this Agreement, this
                  Agreement shall be void and of no further force and effect
                  except for this Section 11, provided that nothing herein shall
                  relieve any party from liability for any breach of this
                  Agreement, and further provided that if the Company becomes
                  obligated to and has paid the fees provided for in Section
                  11(b), the Company shall have no further liability under this

                  Agreement. For greater certainty, the termination of this
                  Agreement shall not affect the Confidentiality Agreement which
                  shall continue in full force and effect following the
                  termination hereof.

         12. PUBLICATION/DISCLOSURE. Except as may otherwise be required by law

hereto agrees that it will not publish, file with any securities commission or
other regulatory authority, or otherwise make public or make any public

announcement or release and to reasonably consider any suggested modifications,
which will be provided by the other party in a timely matter. The parties

                               TERMS OF THE OFFER
                               ------------------

1. GENERAL TERMS. The Offer shall be made to purchase all of the Common Shares
by way of a take-over bid circular prepared in compliance with the Securities
Act (Ontario) and other applicable provincial securities laws and, if necessary,
in accordance with the applicable laws of the United States. The Offer shall be

circumstances prescribed in section 2 below.

         The Purchaser shall have the right to vary the terms of the Offer to

         (a)      increase the consideration offered for the Common Shares;

         (b)      extend the period during which Common Shares may be deposited
                  to the Offer;

         (c)      waive any condition of the Offer or reduce the minimum deposit
                  condition contained in paragraph 4(a) hereof; and

         (d) comply with applicable securities laws.

2. MAXIMUM OFFER PERIOD. The Offeror shall no later than 60 calendar days from
the date of the Offer either:

         (a)      abandon the Offer and return all Common Shares deposited
                  thereunder; or

         (b)      waive any conditions that have not been satisfied, if any, and
                  take up and pay for all Common Shares deposited under the
                  Offer.

                                      - 2 -

         The Offer may be extended by the Offeror beyond the date which is 60
calendar days from the date of the Offer, from time-to-time, in the event that
the Offeror first takes up and pays for all deposited Common Shares.

3. PRICE OF THE OFFER. The Offeror shall pay, for each whole Common Share
validly deposited under the Offer and not withdrawn, $6.25 in cash.

4. CONDITIONS OF THE OFFER. The Offer shall not be subject to any conditions
other than the following:

                  (a) there shall have been validly deposited and not withdrawn
                  pursuant to the Offer a number of Common Shares which
                  constitutes at least 77% of the Common Shares outstanding
                  (calculated on a fully diluted basis but excluding Common
                  Shares issuable pursuant to the Option Agreement) (the
                  "minimum share tender condition");

                  (b) all regulatory approvals which are necessary in connection
                  with the Offer shall have been obtained, and no governmental
                  authority or other person shall have opposed or threatened to
                  oppose the purchase of the Common Shares (including any
                  application for interim relief);

                  (c) the Offeror shall have obtained such orders or exemptive
                  relief from the appropriate governmental or regulatory
                  authorities in each applicable jurisdiction as are necessary
                  in connection with completing the Offer and the transactions
                  contemplated thereby;

                  (d) there shall not exist any prohibition at law against the
                  Offeror making the Offer or taking up and paying for Common
                  Shares deposited under the Offer, or completing any subsequent
                  compulsory acquisition or going private transaction;

                  (e)               (i) no act, action, suit or proceeding shall
                                    have been threatened or taken before or by
                                    any domestic or foreign court, tribunal or

                           (ii)     no law, regulation, policy, directive or
                                    order, whether or not having the force of

                  to own or exercise full rights of ownership of Common Shares
                  or which, if the Offer were consummated, could materially and
                  adversely affect the Company and/or its subsidiaries (taken as
                  a whole), or the Offeror's ability subsequently to effect a
                  going private transaction, or which has had or could
                  reasonably be expected to have a Material Adverse Effect;

          (f)     no law, regulation, policy, directive or order, whether or not
                  having the force of law, shall have been proposed, enacted,
                  promulgated or applied, which has had or could reasonably be
                  expected to have a Material Adverse Effect;

         (g)      there shall not have occurred (or if there shall have occurred
                  prior to the date hereof, there shall not have been generally
                  disclosed or the Purchaser shall not otherwise discover, if
                  not previously disclosed to the Purchaser in writing prior to

                       such negotiations,  the Shareholder had full knowledge of
                       and access to  information  concerning  the Company  such
                       that the  underlying  value of the Company was a material
                       factor  considered by the  Shareholder in arriving at the
                       Offer Price, and there were no non- financial  factors or
                       other  factors  peculiar  to the  Shareholder  which were
                       considered  relevant by the  Shareholder in assessing the
                       price  offered by the  Purchaser  and in  arriving at the
                       Offer Price.

                       of incorporation.

                  (b)  Authority.  The  Purchaser  has all  requisite  corporate
                       power and authority to enter into this Agreement, and the

                       limitations with respect to enforcement imposed by law in
                       connection with bankruptcy or similar proceedings and the
                       availability of equitable remedies.

                       Securities Act (Ontario); and

                  (f)  "Shares"  shall  include any shares into which the Shares
                       may  be   reclassified,   subdivided,   consolidated   or

party shall be entitled to the remedy of specific  performance of such covenants

                  and binding agreement enforceable by the Purchaser against the
                  Shareholder in accordance with its terms subject, however, to
                  limitations with respect to enforcement imposed by law in
                  connection with bankruptcy or similar proceedings, the
                  equitable power of the courts to stay proceedings before them
                  and the execution of judgments and to the extent that
                  equitable remedies such as specific performance and injunction
                  are in the discretion of the court from which they are sought.

          (b)     Ownership of Shares. The Shareholder: (i) is the sole
                  beneficial owner of 1,865,239 Shares which are currently held
                  by the Shareholder; and (ii) upon the acceleration of the
                  vesting thereof, will be the sole beneficial owner of the
                  30,000 Shares issuable upon the exercise of stock options held
                  by the Shareholder to acquire such Shares at an exercise price
                  of U.S. $3.95 per Share. The Shareholder also holds an
                  aggregate of 26,000 vested and unvested options to acquire
                  Shares at exercise prices of U.S. $9.35 per Share or higher.
                  Except as stated in this paragraph, the Shareholder does not
                  own or control, directly or indirectly any other Shares or
                  options, rights or other entitlements to acquire Shares. The
                  Shareholder has the exclusive right to dispose of the

                                       -3-

                  Shareholder's Shares as provided in this Agreement and the
                  Shareholder is not a party to, bound or affected by or subject
                  to, any charter or by-law provision, statute, regulation,
                  judgment, order, decree or law of which a breach would occur
                  as a result of the execution and delivery of this Agreement or
                  the consummation of any of the transactions provided for in
                  this Agreement.

          (c)     Good Title. The Shareholder's Shares to be acquired by the
                  Offeror directly or indirectly from the Shareholder pursuant
                  to the Offer will be acquired with good and marketable title,
                  free and clear of any and all mortgages, liens, charges,
                  restrictions, security interests, adverse claims, pledges,
                  encumbrances and demands or rights of others of any nature or
                  kind whatsoever.

          (d)     No Agreements. No person, firm or corporation has any
                  agreement or option, or any right or privilege (whether by
                  law, pre-emptive or contractual) capable of becoming an
                  agreement or option, for the purchase, requisition or transfer
                  from the Shareholder, or any registered holder of
                  Shareholder's Shares, of any of the Shareholder's Shares, or
                  any interest therein or right thereto, except pursuant to this
                  Agreement.

          (e)     Voting. Neither the Shareholder nor any registered holder of
                  the Shareholder's Shares has previously granted or agreed to
                  grant any ongoing proxy in respect of the Shareholder's Shares
                  or entered into any voting trust, vote pooling or other
                  agreement with respect to the right to vote, call meetings of
                  shareholders or give consents or approvals of any kind as to
                  the Shareholder's Shares.

          (f)     No Proceeding Pending. There is no claim, action, lawsuit,
                  arbitration, mediation or other proceeding pending or, to the
                  best of the knowledge, information and belief of the
                  Shareholder, threatened against the Shareholder, which relates
                  to this Agreement or otherwise materially impairs the ability
                  of the Shareholder to consummate the transactions contemplated
                  hereby.

          (g)     Arm's Length Negotiation. The price payable by the Purchaser
                  for the Shares pursuant to the Offer (the "Offer Price") was
                  arrived at through negotiation between the Shareholder and the
                  Purchaser and, at the time of such negotiations, the
                  Shareholder had full knowledge of and access to information
                  concerning the Company such that the underlying value of the
                  Company was a material factor considered by the Shareholder in
                  arriving at the Offer Price, and there were no non- financial
                  factors or other factors peculiar to the Shareholder which
                  were considered relevant by the Shareholder in assessing the
                  price offered by the Purchaser and in arriving at the Offer
                  Price.

          (h)     Company Public Disclosure Documents. To the best of the
                  knowledge of the Shareholder: (i) all forms, reports,

                  the Company with securities regulatory authority under
                  applicable securities laws (collectively, the "Reports") did
                  not, at the time filed, contain any untrue statement of a
                  material fact or omit to state a 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; (ii) the Company has not filed any
                  confidential material change report with any securities
                  regulatory authority or stock exchange which at the date of
                  this Agreement remains confidential; and (iii) the Company has
                  publicly disclosed in the Reports any information regarding
                  any event, circumstances or action taken or failed to be taken
                  by the Company or its subsidiaries which could individually or
                  in the aggregate reasonably be expected to constitute a
                  Material Adverse Effect.

          (i)     Company Representations and Warranties. To the best of the
                  knowledge of the Shareholder, all of the representations and
                  warranties of the Company set forth in the Offer Agreement are
                  true and correct.

2.2               REPRESENTATIONS AND WARRANTIES OF THE PURCHASER.
                  -----------------------------------------------

                  The Purchaser represents and warrants to the Shareholder as
follows:

          (a)     Organization. The Purchaser is, and the Offeror will be at the
                  date of the Offer, a corporation duly organized and validly
                  existing under the laws of its jurisdiction of incorporation.

          (b)     Authority. The Purchaser has all requisite corporate power and
                  authority to enter into this Agreement, and the Offeror will
                  have at the date of the Offer all necessary corporate power
                  and authority to make the Offer and to carry out the
                  transactions contemplated hereby and by the Offer. The
                  execution and delivery of this Agreement and the consummation
                  of the transactions contemplated hereby have been duly and
                  validly authorized by all necessary corporate action on the
                  part of the Purchaser, and no other corporate proceedings on
                  the part of the Purchaser are necessary to authorize this
                  Agreement. The Agreement has been duly executed and delivered
                  by the Purchaser and constitutes a legal, valid and binding
                  agreement enforceable by the Company against the Purchaser in
                  accordance with its terms, subject, however, to the usual
                  limitations with respect to enforcement imposed by law in
                  connection with bankruptcy or similar proceedings and the
                  availability of equitable remedies.

          (c)     Non-Contravention. Neither the execution and delivery of this
                  Agreement nor the consummation of the transactions
                  contemplated hereby nor compliance with any of the provisions

                  hereof will conflict with or result in any breach of any
                  provision of the constating documents of the Purchaser.

                          its subsidiaries or assets;

                  other than in the Shareholder's capacity as director of the

                  fiduciary duties as a director (but subject to the terms and
                  conditions of the Offer Agreement);

          (b)     notify the Offeror within 24 hours of becoming aware of a
                  proposal which, if made in writing, could constitute a

                  offeror;

          (c)     not option, sell, transfer, pledge, encumber, grant a security
                  interest in, hypothecate or otherwise convey the Shareholder's
                  Shares, or any right or interest therein (legal or equitable),
                  to any person, entity or group or agree to do any of the
                  foregoing, provided that the Shareholder shall be entitled to
                  transfer the Shareholder's Shares to a wholly-owned holding
                  company of the Shareholder incorporated under the Canada
                  Business Corporations Act for the purpose of utilizing the
                  Holdco Alternative referred to in the Offer Agreement, if
                  available;

          (d)     not grant or agree to grant any proxy or other right to vote

                  of the restrictions on its rights with respect to the
                  Shareholder's Shares pursuant to this section 3.1, including,
                  but not limited to, the sale of any direct or indirect holding
                  company of the Shareholder (otherwise than to the Offeror
                  pursuant to the Holdco Alternative, if available) or the
                  granting of a proxy on the Shares of any direct or indirect
                  holding company of the Shareholder which would have,
                  indirectly, the effect prohibited by this section 3.1, and not
                  to take any action which would make any representation or
                  warranty of the Shareholder contained herein untrue or
                  incorrect or have the effect of preventing or disabling the
                  Shareholder from performing its obligations under this
                  Agreement;

          (f)     exercise the voting rights attaching to the Shareholder's
                  Shares and otherwise use its best efforts to oppose any
                  proposed action by the Company, its shareholders, any of its
                  subsidiaries or any other person: (i) in respect of any
                  amalgamation, merger, sale of the Company's or its affiliates'
                  or associates' assets, take-over bid, plan of arrangement,
                  reorganization, recapitalization, shareholder rights plan,
                  liquidation or winding-up of, reverse take-over or other
                  business combination or similar transaction involving the
                  Company or any of its subsidiaries, (ii) which might
                  reasonably be regarded as being directed towards or likely to
                  prevent or delay the take up and payment of Shares deposited
                  under the Offer or the successful completion of the Offer, or
                  (iii) which could result in a Material Adverse Effect;

          (g)     use all reasonable commercial efforts to assist the Purchaser
                  and the Offeror to successfully complete the transactions
                  contemplated by this Agreement;

                  Material Adverse Effect or any event, condition, change or
                  development with respect to the Company which could reasonably
                  be expected to cause the conditions to the Offer not to be
                  satisfied, known or that becomes known to the Shareholder;

          (i)     not purchase or obtain or enter into any agreement or right to
                  purchase any additional Shares from and including the date
                  hereof up until the termination or withdrawal of the Offer
                  (other than pursuant to the exercise of employee stock options
                  by the Shareholder);

          (j)     exercise the 30,000 options held by the Shareholder to acquire
                  Shares at an exercise price of U.S. $3.95 per Share and

                  accordance with the terms of this Agreement, and surrender to
                  the Company for cancellation (without payment of any
                  consideration therefor) all of the other options to acquire
                  Shares that are held by the Shareholder, provided that such
                  surrender for cancellation may be made subject to the
                  condition that, and become effective only upon, the Offeror
                  having taken up and paid for any Shares under the Offer;

          (k)     use all reasonable efforts to preserve intact the goodwill of
                  the Company and its subsidiaries, keep available the services
                  of their respective present officers and key employees, and
                  preserve their business relationships with customers and
                  others having business relationships with them and not engage
                  in any action, directly or indirectly, with the intent to
                  adversely impact the transactions contemplated by the Offer
                  Agreement; and

          (l)     resign as a director of the Company effective at the time and
                  in the manner requested by the Purchaser, after the Offeror
                  takes up and pays for the Shareholder's Shares.

party shall be entitled to the remedy of specific performance of such covenants
or commitments and preliminary and permanent injunctive and other equitable

                             STOCK OPTION AGREEMENT

         STOCK OPTION AGREEMENT, dated as of August 19, 1999, between Motorola,
Inc. ("Grantee") and Metrowerks Inc. ("Issuer").

                              W I T N E S S E T H:

         WHEREAS, concurrently herewith, Grantee and Issuer are entering into an
agreement  providing  for  Grantee to offer to acquire  100% of the  outstanding
Common Shares of Issuer (the "Offer Agreement");

         WHEREAS, the Offer Agreement provides for a maximum Termination Fee (as
defined therein; the "Termination Fee") of U.S. $4,700,000;

         WHEREAS, Grantee and Issuer agree that the value of the Option and the
Termination Fee, together, is not to exceed U.S. $4,700,000;

         WHEREAS,  as a condition and  inducement to Grantee's  execution of the
Offer  Agreement and pursuant to the  transactions  contemplated  thereby and in
consideration  therefor,  Issuer  has  agreed to grant  Grantee  the  Option (as
hereinafter defined); and

         WHEREAS, the Board of Directors of Issuer has approved the grant of the
Option and the Offer Agreement prior to the execution hereof;

         NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  mutual
covenants  and  agreements  set forth  herein  and in the Offer  Agreement,  the
parties hereto agree as follows:

         1.       THE OPTION.

         (a)  Issuer  hereby  grants to Grantee  an  unconditional,  irrevocable
option  (the  "Option")  to  purchase,  subject  to the terms  hereof,  up to an
aggregate  of 2,913,172  fully paid and  nonassessable  common  shares of Issuer
("Common  Shares") at a price per share  equal to U.S.  $6.25  (such  price,  as
adjusted if applicable,  the "Option Price") or an aggregate  purchase price for
the Common Shares of U.S. $18,207,325 (the "Aggregate Option Price");  provided,
however,  that in no event  shall the number of shares for which this  Option is
exercisable  exceed 19.9% of the issued and  outstanding  Common Shares (without
giving  effect to any exercise of this  Option) at the time of exercise  without
giving  effect to the Common  Shares  issued or issuable  under the Option.  The
number of Common Shares that may be received upon the exercise of the Option and
the Option Price are subject to adjustment as herein set forth.


         (b) In the  event  that any  additional  Common  Shares  are  issued or
otherwise  become  outstanding  after  the date of this  Agreement  (other  than

pursuant to this  Agreement  and other than  pursuant to an event  described  in
Section 5(a) hereof), the number of Common Shares subject to the Option shall be
increased so that,  after such  issuance,  such number  together with any Common
Shares previously  issued pursuant hereto,  equals 19.9% of the number of Common
Shares then issued and  outstanding  (without  giving  effect to any exercise of
this Option)  without giving effect to any shares subject or issued  pursuant to
the  Option.  Nothing  contained  in  this  Section  1(b) or  elsewhere  in this
Agreement shall be deemed to authorize Issuer or Grantee to breach any provision
of the Offer Agreement.  Any such increase shall not affect the Aggregate Option
Price.

         2.       EXERCISE; CLOSING.

         (a) Grantee  and/or any other  person that shall become a holder of all
or part of the Option in accordance  with the terms of this Agreement (each such
person being  referred to herein as the  "Holder")  may exercise the Option,  in
whole or part,  if,  but only if,  the  Termination  Fee has  become  payable (a
"Triggering  Event") and such exercise is prior to the occurrence of an Exercise
Termination Event (as hereinafter defined).

         (b) Each of the following shall be an "Exercise Termination Event":

                  (i)      the passage of  thirteen  (13) months (or such longer
                           period as provided  in Section 10) after  termination
                           of the Offer Agreement; or

                  (ii)     the  completion  of  the  acquisition  of  all of the
                           issued  and  outstanding  Common  Shares of Issuer by
                           Grantee   or  a  direct  or   indirect   wholly-owned
                           subsidiary of Grantee; or

                  (iii)    the  payment  of  any   combination   of  the  Option
                           Repurchase Price or the Option Share Repurchase Price
                           (as defined in Section 7(a) hereof) or the Substitute
                           Option  Repurchase  Price  or  the  Substitute  Share
                           Repurchase  Price (as defined in Section 9(a) hereof)
                           aggregating U.S. $4,700,000.

         (c) In the event  Holder is  entitled  to and  wishes to  exercise  the
Option (or any portion  thereof),  it shall send to Issuer a written notice (the
date of which being herein referred to as the "Notice Date")  specifying (i) the
total  number of shares it will  purchase  pursuant to such  exercise and (ii) a
place and date not earlier than three  business  days nor later than 60 business
days from the Notice Date for the closing of such purchase (the "Closing Date");
provided,  that if the closing of such purchase  cannot be consummated by reason
of any applicable judgment,  injunction,  decree, order, law or regulation,  the
period of time that would  otherwise  run  pursuant to this  sentence  shall run
instead from the date on which such  restriction on consummation  has expired or
been  terminated;  and  provided,  further,  that if  prior  notification  to or
approval of any  regulatory or antitrust  agency is required in connection  with
such purchase, Holder shall promptly file the required notice or application for
approval,  shall promptly notify Issuer of such filing, and shall  expeditiously
process

                                      - 2 -

<PAGE>



the same and the  period  of time that  otherwise  would  run  pursuant  to this
sentence  shall run  instead  from the date on which any  required  notification
periods have expired or been terminated or such approvals have been obtained and
any requisite waiting period or periods shall have passed.  Issuer agrees to use
its best efforts to obtain any and all regulatory or other  approvals  necessary
in connection  with the granting or exercise of the Option.  Any exercise of the
Option,  in whole  or in  part,  shall be  deemed  to occur on the  Notice  Date
relating to that portion of the exercise of the Option.

         (d) At the closing  referred to in  subsection  (c) of this  Section 2,
Holder  shall (i) pay to Issuer  the  aggregate  purchase  price for the  Common
Shares purchased pursuant to an exercise of the Option in immediately  available
funds by wire  transfer to a bank account  designated  by Issuer,  provided that
failure or refusal of Issuer to designate such a bank account shall not preclude
Holder from exercising the Option by delivery of a certified check or bank draft
and (ii) present and surrender this Agreement to Issuer,  against  delivery,  in
the case of any  exercise  of the  Option  in part  only,  of the new  Agreement
referred to in subsection (e) of this Section 2.

         (e) At such closing,  simultaneously  with the delivery of  immediately
available  funds as provided in  subsection  (d) of this Section 2, Issuer shall
deliver  to Holder a  certificate  or  certificates  representing  the number of
Common Shares purchased by Holder and, if the Option should be exercised in part
only, a new Agreement  evidencing  the rights of the Holder  thereof to purchase
the balance of the shares purchasable hereunder, which new Agreement shall be on
the same terms and conditions as are set forth herein except with respect to the
number of Common  Shares  issuable  pursuant  thereto,  which  shall be  reduced
accordingly in respect of any prior exercises of the Option.

         (f) Certificates for Common Shares delivered at a closing hereunder may
be endorsed with a restrictive legend that shall read substantially as follows:

                  "The transfer of the shares represented by this certificate is
                  subject  to  certain   resale   restrictions   arising   under
                  applicable   securities  laws  (including  the  United  States
                  Securities Act of 1933, as amended)."

         It is  understood  and agreed that the above legend shall be removed by
delivery of  substitute  certificate(s)  without such  reference if Holder shall
have  delivered to Issuer a copy of a letter from the United  States  Securities
and Exchange Commission or a written opinion of counsel of nationally recognized
standing addressed to Issuer, in form and substance  reasonably  satisfactory to
Issuer,  to the effect  that such  legend is not  required  for  purposes of the
Unites  States  Securities  Act of 1933,  as amended  (the "1933  Act") or other
applicable securities laws. In addition,  such certificates shall bear any other
legend as may be required by law.

         (g) Upon the  giving  by Holder  to  Issuer  of the  written  notice of
exercise of the Option  provided for under  subsection (c) of this Section 2 and
the tender of the  applicable  purchase price in  immediately  available  funds,
Holder shall be deemed to be the holder of record of the Common Shares  issuable
upon such  exercise,  notwithstanding  that the share  transfer  books of Issuer
shall then

                                      - 3 -

<PAGE>



be closed or that certificates representing such Common Shares shall not then be
actually  delivered to Holder.  Issuer shall pay all  expenses,  and any and all
United  States  federal,  state and local  taxes and other  charges  that may be
payable  in  connection  with  the  preparation,  issue  and  delivery  of share
certificates  under  this  Section  2 in the  name of  Holder  or its  assignee,
transferee or designee.

         3.       COVENANTS OF ISSUER.

         In  addition  to its other  agreements  and  covenants  herein,  Issuer
agrees:

         (a) that it shall at all times maintain,  free from any subscription or
preemptive rights,  sufficient authorized but unissued Common Shares so that the
Option may be exercised without additional  authorization of Common Shares after
giving effect to all other options,  warrants,  convertible securities and other
rights of third parties to purchase Common Shares from Issuer or to cause Issuer
to issue Common Shares;

         (b) that it will not, by charter  amendment or through  reorganization,
consolidation,  merger, dissolution or sale of assets, or by any other voluntary
act,  avoid  or  seek to  avoid  the  observance  or  performance  of any of the
covenants,  stipulations or conditions to be observed or performed  hereunder by
Issuer;

         (c)  promptly  to take all action as may from time to time be  required
(including  complying with all  applicable  notification,  filing  reporting and
waiting period requirements under the  Hart-Scott-Rodino  Act or otherwise,  and
cooperating  fully with  Holder in  preparing  any  applications  or notices and
providing such  information  to any  regulatory  authority as it may require) in
order to permit Holder to exercise the Option and Issuer duly and effectively to
issue Common Shares  pursuant hereto and to protect the rights of Holder against
dilution; and

         (d) it will  forthwith  following the execution of this  Agreement make
application,  and  thereafter use its best efforts to (i) secure the approval of
The Toronto  Stock  Exchange  (the "TSE") and the NASDAQ  Market,  and any other
stock  exchange  or market on which the  Common  Shares are listed or quoted for
trading,  in respect of the  issuance  and exercise of the Option and (ii) cause
the  Common  Shares  to be issued  pursuant  to the  Option to be  conditionally
approved  for listing (to the extent  they are not already so  approved)  on the
TSE,  the NASDAQ  Market and all other stock  exchanges or markets on which such
Common  Shares  are then  listed or quoted  for  trading,  subject  to the usual
conditions of the TSE and, in the case of the NASDAQ Market, subject to official
notice  of  issuance.  Issuer  agrees  to  provide  Grantee  with  copies of all
correspondence  with all stock  exchanges  or  markets  in  connection  with the
provisions of this  paragraph  and to provide  Grantee with the  opportunity  to
participate  in the  process  of  obtaining,  and any  proceedings  relating  to
obtaining, all such approvals.

         4.       EXCHANGE; REPLACEMENT.

<PAGE>



         This  Agreement  (and the Option  evidenced  hereby) are  exchangeable,
without  expense,  at the option of Holder,  upon  presentation and surrender of
this Agreement at the principal office of Issuer, for other Agreements providing
for Options of different denominations entitling the holder thereof to purchase,
on the same terms and subject to the same conditions as are set forth herein, in
the aggregate the same number of Common Shares purchasable hereunder.  The terms
"Agreement"  and  "Option" as used herein  include  any  Agreements  and related
Options  for  which  this  Agreement  (and the  Option  granted  hereby)  may be
exchanged.  Upon receipt by Issuer of evidence reasonably  satisfactory to it of
the loss, theft,  destruction or mutilation of this Agreement,  and (in the case
of loss, theft or destruction) of reasonably satisfactory  indemnification,  and
upon surrender and  cancellation  of this Agreement,  if mutilated,  Issuer will
execute  and  deliver a new  Agreement  of like  tenor  and  date.  Any such new
Agreement  executed and delivered  shall  constitute  an additional  contractual
obligation on the part of Issuer,  whether or not the Agreement so lost, stolen,
destroyed or mutilated shall at any time be enforceable by any person other than
the holder of the new Agreement.

         5.       ADJUSTMENTS.

         In addition to the  adjustment  in the number of Common Shares that are
purchasable  upon  exercise  of the  Option  pursuant  to  Section  1(b) of this
Agreement,  the number of Common  Shares  purchasable  upon the  exercise of the
Option and the Option Price shall be subject to adjustment  from time to time as
provided in this Section 5.

         (a) In the event of any change in, or  distributions in respect of, the
Common   Shares   by   reason   of   stock   dividends,    split-ups,   mergers,
recapitalizations,  combinations, subdivisions, conversions, exchanges of shares
or the like,  the type and number of Common  Shares  purchasable  upon  exercise
hereof shall be  appropriately  adjusted and proper  provision  shall be made so
that (i) any Holder  shall  receive  upon  exercise of the Option the number and
class of shares, other securities,  property or cash that such Holder would have
received in respect of the Common Shares purchasable upon exercise of the Option
if the Option had been  exercised and such Common Shares had been issued to such
Holder  immediately  prior  to  such  event  or the  record  date  therefor,  as
applicable,  and (ii) in the event that any  additional  Common Shares are to be
issued or otherwise  become  outstanding  as a result of any such change  (other
than  pursuant  to an  exercise  of the  Option),  the  number of Common  Shares
purchasable  upon exercise of the Option shall be increased so that,  after such
issuance and  together  with Common  Shares  previously  issued  pursuant to the
exercise of the Option (as adjusted on account of any of the  foregoing  changes
in the Common Shares), it equals 19.9% of the number of Common Shares issued and
outstanding  (without giving effect to any exercise of this Option)  immediately
after the consummation of such change.

         (b)  Whenever the number of Common  Shares  purchasable  upon  exercise
hereof is  adjusted as  provided  in this  Section 5, the Option  Price shall be
adjusted by multiplying  the Option Price by a fraction,  the numerator of which
shall  be  equal  to the  number  of  Common  Shares  purchasable  prior  to the
adjustment  and the  denominator of which shall be equal to the number of Common
Shares purchasable after the adjustment, with the intention that such adjustment
in the

                                      - 5 -

<PAGE>



Option  Price will result in the Option  having the same  economic  value to the
Holder  following  such  adjustment  in the Option  Price as it did prior to the
event giving rise to the adjustment in the number of Common Shares  provided for
in this Section 5. More  specifically,  in no event shall the  Aggregate  Option
Price increase.

         6.       REGISTRATION.

         (a)  If  any  Triggering  Event  has  occurred  prior  to  an  Exercise
Termination  Event,  Issuer shall,  at the request of Grantee  delivered  within
twelve  (12)  months (or such later  period as  provided  in Section 10) of such
Triggering  Event  (whether  on its own  behalf or on  behalf of any  subsequent
holder of this  Option  (or part  thereof)  or any of the Common  Shares  issued
pursuant hereto),  promptly prepare,  file and keep current a shelf registration
statement under the 1933 Act covering any shares issued and issuable pursuant to
this Option and shall use its reasonable best efforts to cause such registration
statement to become  effective and remain current in order to permit the sale or
other  disposition of any Common Shares issued upon total or partial exercise of
this  Option  ("Option  Shares")  in  accordance  with any  plan of  disposition
requested by Grantee.  Issuer will use its reasonable best efforts to cause such
registration statement promptly to become effective and then to remain effective
for  such  period  not in  excess  of 180 days  from  the day such  registration
statement  first  becomes  effective or such  shorter time as may be  reasonably
necessary  to effect such sales or other  dispositions.  Grantee  shall have the
right to demand  two such  registrations.  Issuer  shall  bear the costs of such
registrations (including, but not limited to, Issuer's attorneys' fees, printing
costs and  filing  fees,  except  for  underwriting  discounts  or  commissions,
brokers'  fees and the fees  and  disbursements  of  Grantee's  counsel  related
thereto).  The  foregoing  notwithstanding,  if, at the time of any  request  by
Grantee  for  registration  of Option  Shares as  provided  above,  Issuer is in
registration with respect to an underwritten public offering by Issuer of Common
Shares,  and if in the  good  faith  judgment  of the  managing  underwriter  or
managing  underwriters,  or, if none, the sole underwriter or  underwriters,  of
such  offering the  inclusion  of the Option  Shares  would  interfere  with the
successful  marketing  of the Common  Shares  offered  by Issuer,  the number of
Option Shares otherwise to be covered in the registration statement contemplated
hereby may be reduced; provided, however, that after any such required reduction
the number of Option  Shares to be included in such  offering for the account of
Holder shall constitute at least 25% of the total number of shares to be sold by
Holder and Issuer in the aggregate; and provided further,  however, that if such
reduction  occurs,  then  Issuer  shall file a  registration  statement  for the
balance as promptly as practicable  thereafter as to which no reduction pursuant
to this Section 6 shall be permitted  or occur and Holder  shall  thereafter  be
entitled  to one  additional  registration  and the  twelve  (12)  month  period
referred  to in the  first  sentence  of this  section  shall  be  increased  to
twenty-four  (24)  months.  Each  such  Holder  shall  provide  all  information
reasonably requested by Issuer for inclusion in any registration statement to be
filed  hereunder.  If  requested  by any such  Holder  in  connection  with such
registration, Issuer shall become a party to any underwriting agreement relating
to the sale of such  shares,  but only to the  extent  of  obligating  itself in
respect  of  representations,   warranties,  indemnities  and  other  agreements
customarily included in such underwriting  agreements for Issuer. Upon receiving
any request  under this Section 6 from any Holder,  Issuer agrees to send a copy
thereof  to any other  person  known to Issuer to be  entitled  to  registration
rights under this Section 6, in each

                                      - 6 -

<PAGE>



case by promptly mailing the same, postage prepaid,  to the address of record of
the persons  entitled to receive  such copies.  Notwithstanding  anything to the
contrary  contained herein,  in no event shall the number of registrations  that
Issuer is  obligated  to effect be  increased  by reason of the fact that  there
shall be more than one Holder as a result of any  assignment or division of this
Agreement.  Securities  held by persons  entitled to  "piggy-back"  registration
rights pursuant to any contractual commitment of the Company may be included for
registration under the registration  statement referred to in this Section 6(a),
but only if such  inclusion  (i) would not reduce the number of Common Shares to
be sold by Holder and (ii) could not reasonably be expected to adversely  affect
the offering being made by Holder pursuant to the registration statement.

         (b) In the event that  Grantee  shall  desire to sell any of the Common
Shares issued upon total or partial  exercise of the Option and such sale in the
manner  proposed  by Grantee  requires,  in the  opinion of counsel to  Grantee,
qualification  of such  Common  Shares  for  resale  under  applicable  Canadian
securities  laws,  Issuer shall  cooperate with Grantee and any  underwriters in
qualifying  such  Common  Shares  for  resale,  including,  without  limitation,
promptly filing a prospectus  which complies with the requirements of applicable
Canadian  securities laws and entering into an underwriting  agreement with such
underwriters  upon such terms and  conditions  as are  customarily  contained in
underwriting agreements with respect to secondary distribution.

         (c) If Common Shares are qualified  for  distribution  pursuant to this
Section 6, Issuer agrees (i) to furnish copies of the prospectus relating to the
Common Shares  covered  thereby in such numbers as Grantee may from time to time
reasonably  request,  and (ii) if any event  shall occur as a result of which it
becomes  necessary to amend or supplement  any  prospectus,  to prepare and file
under the applicable  securities  laws such amendments and supplements as may be
necessary to keep  available for at least 60 days a prospectus  covering  Common
Shares meeting the  requirements of such securities laws, and to furnish Grantee
such numbers of copies of the  prospectus,  as amended or  supplemented,  as may
reasonably  be  requested.  Issuer  shall  bear the  cost of the  qualification,
including but not limited to, all filing fees,  printing expenses,  underwriting
fees and fees and  disbursements  of its counsel and counsel and accountants for
Grantee.

         (d) Issuer shall  indemnify and hold harmless  Grantee,  its affiliates
and its  officers  and  directors  from and against any and all losses,  claims,
damages,  liabilities  and expenses  arising out of or based upon any statements
contained in or omissions or alleged omissions from, each registration statement
or Canadian prospectus filed pursuant to this Section 6; provided, however, that
this provision shall not apply to any loss, liability,  claim, damage or expense
to the extent it arises out of any untrue statement or omission made in reliance
upon and in conformity with written information  furnished to Issuer by Grantee,
its affiliates and its officers and other  representatives  expressly for use in
any  registration  statement or Canadian  prospectus (or any amendment  thereto)
filed  pursuant to this Section 6. Issuer shall also indemnify and hold harmless
each  underwriter and each person who controls any  underwriter  against any and
all losses,  claims,  damages,  liabilities and expenses arising out of or based
upon any statements  contained in or omissions or alleged  omissions  from, each
registration  statement or Canadian prospectus filed pursuant to this Section 6;
provided,  however,  that this provision shall not apply to any loss, liability,
claim, damage or expense to the

                                      - 7 -

<PAGE>



extent it arises out of any untrue  statement or omission made in writing by the
underwriters  expressly  for  use  in any  registration  statement  or  Canadian
prospectus (or any amendment thereto) filed pursuant to this Section 6.

         (e) In the event that Grantee so  requests,  the closing of the sale or
other  disposition  of the  Common  Shares  or other  securities  pursuant  to a
registration  statement or Canadian prospectus filed pursuant to Section 6 shall
occur substantially simultaneously with the exercise of the Option.

         (f) If any of the Common  Shares  acquired  upon exercise of the Option
are not yet listed on any stock  exchange or  included  for trading on any stock
market, or have only been  conditionally  listed or included for trading subject
to notice of issuance,  Issuer,  upon the request of Holder,  shall promptly use
its best efforts to obtain  unconditional  approval of such listing or inclusion
for trading as soon as practicable.

         7.       REPURCHASE OF OPTION AND/OR OPTION SHARES.

         (a) At any  time  and  from  time to time  after  the  occurrence  of a
Triggering Event (i) at the request of Holder,  delivered in writing prior to an
Exercise  Termination  Event (or such later  period as provided in Section  10),
Issuer (or any successor  thereto) shall  repurchase the Option (or such portion
of the Option as Holder  shall  designate)  from Holder at a price (the  "Option
Repurchase  Price") equal to the amount by which (A) the market/offer  price (as
defined below) exceeds (B) the Option Price,  multiplied by the number of shares
for which this Option may then be exercised and (ii) at the request of the owner
of Option Shares from time to time (the "Owner"),  delivered in writing prior to
an Exercise  Termination Event (or such later period as provided in Section 10),
Issuer (or any successor  thereto)  shall  repurchase  such number of the Option
Shares  from  Owner as Owner  shall  designate  at a price  (the  "Option  Share
Repurchase  Price") equal to the market/offer  price multiplied by the number of
Option  Shares so  designated.  The term  "market/offer  price"  shall  mean the
highest of (i) the price per Common  Share at which a tender or  exchange  offer
therefor has been made,  (ii) the price per Common Share to be paid by any third
party pursuant to an agreement with Issuer,  (iii) the highest trading price for
Common  Shares on the TSE or the NASDAQ Market (or, if the Common Shares are not
then  listed on the TSE or the  NASDAQ  Market,  any  other  stock  exchange  or
automated quotation system on which the Common Shares are then listed or quoted)
within the six-month period  immediately  preceding the date Holder gives notice
of the required  repurchase of this Option or Owner gives notice of the required
repurchase of Option Shares,  as the case may be, or (iv) in the event of a sale
of all or substantially  all Issuer's  assets,  the sum of the net price paid in
such sale for such  assets and the current  market  value of the  remaining  net
assets of Issuer as determined  by a nationally  recognized  investment  banking
firm selected by Holder or Owner, as the case may be, and reasonably  acceptable
to Issuer,  divided by the number of Common Shares of Issuer  outstanding at the
time  of such  sale,  which  determination,  absent  manifest  error,  shall  be
conclusive for all purposes of this Agreement.  In determining the  market/offer
price,  the value of  consideration  other  than cash shall be  determined  by a
nationally  recognized  investment  banking firm selected by Holder or Owner, as
the case may be,  and  reasonably  acceptable  to Issuer,  which  determination,
absent manifest error, shall be conclusive for all purposes of this Agreement.

                                      - 8 -

<PAGE>




         (b)  Holder and Owner,  as the case may be, may  exercise  its right to
require Issuer to repurchase  the Option and any Option Shares  pursuant to this
Section 7 by surrendering for such purpose to Issuer, at its principal office, a
copy of this  Agreement  or  certificates  for  Option  Shares,  as  applicable,
accompanied by a written notice or notices  stating that Holder or Owner, as the
case may be,  elects to require  Issuer to  repurchase  this  Option  and/or the
Option Shares in accordance  with the  provisions of this Section 7. As promptly
as  practicable,  and in any event within five business days after the surrender
of the Option and/or certificates  representing Option Shares and the receipt of
such notice or notices  relating  thereto,  Issuer shall  deliver or cause to be
delivered to Holder the Option Repurchase Price and/or to Owner the Option Share
Repurchase  Price  therefor  or the  portion  thereof  that  Issuer  is not then
prohibited under applicable law and regulation from so delivering.

         (c) To the extent that Issuer is  prohibited  under  applicable  law or
regulation from repurchasing the Option and/or the Option Shares in full, Issuer
shall immediately so notify Holder and/or Owner and thereafter  deliver or cause
to be delivered, from time to time, to Holder and/or Owner, as appropriate,  the
portion of the Option  Repurchase Price and the Option Share  Repurchase  Price,
respectively,  that it is no longer  prohibited  from  delivering,  within  five
business  days  after  the date on which  Issuer  is no  longer  so  prohibited;
provided,  however,  that if Issuer at any time  after  delivery  of a notice of
repurchase  pursuant to  paragraph  (b) of this  Section 7 is  prohibited  under
applicable  law or  regulation  from  delivering  to  Holder  and/or  Owner,  as
appropriate,  the Option Repurchase Price and the Option Share Repurchase Price,
respectively,  in full (and Issuer hereby  undertakes to use its reasonable best
efforts to obtain all required  regulatory  and legal  approvals and to file any
required  notices  as  promptly  as  practicable  in  order to  accomplish  such
repurchase),  Holder or Owner may revoke its notice of  repurchase of the Option
and/or the Option Shares  whether in whole or to the extent of the  prohibition,
whereupon,  in the latter  case,  Issuer  shall  promptly  (i) deliver to Holder
and/or Owner, as appropriate, that portion of the Option Repurchase Price and/or
the Option Share Repurchase Price that Issuer is not prohibited from delivering;
and (ii) deliver, as appropriate,  either (A) to Holder, a new Agreement, on the
same  terms  and  subject  to the  same  conditions  as are  set  forth  herein,
evidencing the right of Holder to purchase that number of Common Shares obtained
by multiplying the number of Common Shares for which the  surrendered  Agreement
was  exercisable  at the time of  delivery  of the  notice  of  repurchase  by a
fraction, the numerator of which is the Option Repurchase Price less the portion
thereof  theretofore  delivered  to Holder and the  denominator  of which is the
Option  Repurchase  Price,  and/or (B) to Owner,  a  certificate  for the Option
Shares it is then so prohibited from  repurchasing.  If an Exercise  Termination
Event shall have occurred prior to the date of the notice by Issuer described in
the first sentence of this subsection (c), or shall be scheduled to occur at any
time before the  expiration  of a period  ending on the thirtieth day after such
date,  Holder shall  nonetheless have the right to exercise the Option until the
expiration of such 30-day period.

                                      - 9 -

         8.       SUBSTITUTE OPTION.

         (a) In the event that prior to an Exercise  Termination  Event,  Issuer
shall enter into an agreement (i) to consolidate  with or merge into any person,
other  than  Grantee  or any of its  subsidiaries  and  Issuer  shall not be the
continuing or surviving  corporation of such  consolidation  or merger,  (ii) to
permit any person, other than Grantee or any of its subsidiaries,  to merge into
Issuer and Issuer shall be the continuing or surviving or acquiring corporation,
but in connection with such merger,  the then outstanding Common Shares shall be
changed into or exchanged  for stock or other  securities of any other person or
cash or any other  property or the then  outstanding  Common  Shares shall after
such  merger  represent  less  than  50% of the  outstanding  shares  and  share
equivalents  of the merged or acquiring  company,  or (iii) to sell or otherwise
transfer all or substantially all of its or any Significant  Subsidiary's assets
to any person,  other than to Grantee or any of its  subsidiaries,  then, and in
each such case,  the  agreement  governing  such  transaction  shall make proper
provision  so  that  the  Option  shall,  upon  the  consummation  of  any  such
transaction  and upon the terms and  conditions  set forth herein,  be converted
into, or exchanged for, an option (the "Substitute  Option"), at the election of
Holder, of either (x) the Acquiring  Corporation (as hereinafter defined) or (y)
any person that controls the Acquiring Corporation.

         (b) The following terms have the meanings indicated:

                  (i)      "Acquiring Corporation" shall mean (i) the continuing
                           or surviving person of a consolidation or merger with
                           Issuer  (if  other  than  Issuer),  (ii)  Issuer in a
                           merger in which Issuer is the continuing or surviving
                           or acquiring person,  and (iii) the transferee of all
                           or  substantially  all of  Issuer's  assets  (or  the
                           assets of a Significant Subsidiary of Issuer).

                  (ii)     "Substitute  Shares" shall mean the shares of capital
                           stock (or similar equity  interest) with the greatest
                           voting  power in respect of the election of directors
                           (or other persons similarly responsible for direction
                           of the  business  and  affairs)  of the issuer of the
                           Substitute Option.

                  (iii) "Assigned Value" shall mean the  market/offer  price, as
defined in Section 7.

                    (iv) "Average  Price" shall mean the average  closing  price
                         per Substitute  Share, on the principal  trading market
                         on which  such  shares  are  traded  as  reported  by a
                         recognized source,  for one year immediately  preceding
                         the consolidation,  merger or sale in question,  but in
                         no  event   higher  than  the  closing   price  of  the
                         Substitute  Shares on such market on the day  preceding
                         such  consolidation,  merger or sale;  provided that if
                         Issuer is the  issuer  of the  Substitute  Option,  the
                         Average  Price  shall be  computed  with  respect  to a
                         common share  issued by the person  merging into Issuer
                         or by any company  which  controls or is  controlled by
                         such person, as Holder may elect.

                  (v)      "Significant  Subsidiary" has the meaning ascribed to
                           such   term  in  Rule  405   promulgated   under  the
                           Securities  Exchange  Act of 1934,  as  amended  (the
                           "1934 Act"),  as if the Company  were the  registrant
                           referred to therein.

         (c) The  Substitute  Option  shall have the same  terms as the  Option,
provided that if the terms of the Substitute  Option cannot,  for legal reasons,
be the same as the Option,  such terms shall be as similar as possible and in no
event less  advantageous  to Holder.  The issuer of the Substitute  Option shall
also enter into an agreement  with the then Holder or Holders of the  Substitute
Option in substantially the same form as this Agreement (after giving effect for
such  purpose  to the  provisions  of  Section  9),  which  agreement  shall  be
applicable to the Substitute Option.

         (d) The  Substitute  Option  shall be  exercisable  for such  number of
Substitute  Shares as is equal to the Assigned Value multiplied by the number of
Common  Shares  for which the Option was  exercisable  immediately  prior to the
event  described in the first  sentence of Section 8(a),  divided by the Average
Price.  The exercise price of the Substitute  Option per Substitute  Share shall
then be equal to the Option Price  multiplied  by a fraction,  the  numerator of
which shall be the number of Common Shares for which the Option was  exercisable
immediately  prior to the event  described in the first sentence of Section 8(a)
and the denominator of which shall be the number of Substitute  Shares for which
the Substitute  Option is  exercisable.  In no event shall the Aggregate  Option
Price be increased.

         (e) In no event, pursuant to any of the foregoing paragraphs, shall the
number of shares purchasable upon exercise of the Substitute Option exceed 19.9%
of the Substitute  Shares then issued and outstanding  (without giving effect to
any exercise of this Option) at the time of exercise  (without  giving effect to
Substitute Shares issued or issuable under the Substitute  Option). In the event
that the  Substitute  Option  would be  exercisable  for more than  19.9% of the
Substitute  Shares then issued and  outstanding  prior to exercise  but for this
clause (e), the issuer of the Substitute Option (the "Substitute Option Issuer")
shall make a cash  payment to Holder equal to the excess of (i) the value of the
Substitute  Option  without  giving effect to the  limitation in this clause (e)
over  (ii)  the  value of the  Substitute  Option  after  giving  effect  to the
limitation in this clause (e). This difference in value shall be determined by a
nationally  recognized  investment  banking  firm  selected  by Grantee  (or, if
Grantee is not then the Holder owning Options with respect to the largest number
of Substitute Shares, the largest Holder), which determination,  absent manifest
error, shall be conclusive for all purposes of this Agreement.

         (f) In addition to any other  restrictions or covenants,  Issuer agrees
that it shall  not enter or agree to enter  into any  transaction  described  in
Section 8(a) unless the Acquiring  Corporation  and any person that controls the
Acquiring  Corporation  (i)  assume in  writing  all the  obligations  of Issuer
hereunder  and (ii) take all other  actions  that may be  necessary  so that the
provisions of this Section 8 are given full force and effect.  Without  limiting
the  foregoing,  the  Acquiring  Corporation  and any person that  controls  the
Acquiring  Corporation  shall take any action that may be necessary  (x) so that
the holders of the other common shares issued by the Substitute Option Issuer or
any successor to

                                     - 11 -

<PAGE>



the  Substitute  Option Issuer are not entitled to exercise any rights by reason
of the  issuance  or exercise  of the  Substitute  Option and (y) to prevent the
exercise of any rights by the holders of the other common  shares  issued by the
Substitute  Option Issuer or any successor to the Substitute  Option Issuer that
(A) any holder of the  Substitute  Option  (each such person  being  referred to
herein as a "Substitute Option Holder") or any holder of Substitute Shares (each
such person being  referred to herein as a "Substitute  Share Owner")  purchased
upon exercise of the  Substitute  Option would be  prohibited or precluded  from
exercising or (B) the exercise of which would adversely affect the rights of any
Substitute  Option Holder under the agreement for such Substitute  Option or the
transactions contemplated by the Offer Agreement.

         9.       REPURCHASE OF SUBSTITUTE OPTION.

         (a) At the written  request of a Substitute  Option  Holder at any time
and from  time to time,  the  Substitute  Option  Issuer  shall  repurchase  the
Substitute  Option (or such portion of the  Substitute  Option as the Substitute
Option Holder shall designate) from the Substitute Option Holder at a price (the
"Substitute  Option  Repurchase  Price")  equal to the  amount  by which (i) the
Highest Closing Price (as hereinafter  defined)  exceeds (ii) the exercise price
of the  Substitute  Option,  multiplied by the number of  Substitute  Shares for
which the  Substitute  Option may then be  exercised,  and at the request of the
Substitute  Share Owner,  the  Substitute  Option  Issuer shall  repurchase  the
Substitute Shares at a price (the "Substitute Share Repurchase  Price") equal to
the Highest  Closing  Price  multiplied  by the number of  Substitute  Shares so
designated.  The term  "Highest  Closing  Price" shall mean the highest  closing
price for Substitute  Shares within the six-month period  immediately  preceding
the date the Substitute Option Holder gives notice of the required repurchase of
the Substitute Option or the Substitute Share Owner gives notice of the required
repurchase of the Substitute Shares, as applicable.

         (b) The Substitute Option Holder and the Substitute Share Owner, as the
case may be, may exercise its respective rights to require the Substitute Option
Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to
this Section 9 by surrendering for such purpose to the Substitute Option Issuer,
at its principal  office,  the agreement for such Substitute  Option (or, in the
absence of such an agreement,  a copy of this Agreement) and/or certificates for
Substitute  Shares  accompanied by a written notice or notices  stating that the
Substitute  Option  Holder or the  Substitute  Share Owner,  as the case may be,
elects to require the  Substitute  Option  Issuer to repurchase  the  Substitute
Option and/or the  Substitute  Shares in accordance  with the provisions of this
Section 9. As promptly as practicable and in any event within five business days
after the surrender of the Substitute  Option and/or  certificates  representing
Substitute  Shares and the receipt of such notice or notices  relating  thereto,
the  Substitute  Option  Issuer  shall  deliver or cause to be  delivered to the
Substitute  Option Holder the Substitute  Option  Repurchase Price and/or to the
Substitute  Share Owner the Substitute  Share  Repurchase  Price therefor or the
portion thereof which the Substitute  Option Issuer is not then prohibited under
applicable law and regulation from so delivering.

         (c) To the extent that the Substitute Option Issuer is prohibited under
applicable law or regulation from  repurchasing the Substitute Option and/or the
Substitute Shares in part or in full, the

                                     - 12 -

<PAGE>



Substitute  Option  Issuer shall  immediately  so notify the  Substitute  Option
Holder and/or the Substitute  Share Owner and thereafter  deliver or cause to be
delivered,  from  time to time,  to the  Substitute  Option  Holder  and/or  the
Substitute  Share Owner,  as appropriate,  the portion of the Substitute  Option
Repurchase  Price and/or the Substitute Share  Repurchase  Price,  respectively,
which it is no longer prohibited from delivering,  within five (5) business days
after the date on which the Substitute Option Issuer is no longer so prohibited;
provided,  however,  that if the  Substitute  Option Issuer is at any time after
delivery of a notice of repurchase  pursuant to subsection (b) of this Section 9
prohibited  under applicable law or regulation from delivering to the Substitute
Option Holder and/or the Substitute Share Owner, as appropriate,  the Substitute
Option Repurchase Price and the Substitute Share Repurchase Price, respectively,
in full (and the Substitute  Option Issuer shall use its best efforts to receive
all required  regulatory and legal approvals as promptly as practicable in order
to accomplish such  repurchase),  the Substitute Option Holder and/or Substitute
Share Owner may revoke its notice of repurchase of the Substitute  Option or the
Substitute Shares either in whole or to the extent of prohibition, whereupon, in
the latter case, the Substitute  Option Issuer shall promptly (i) deliver to the
Substitute Option Holder or Substitute Share Owner, as appropriate, that portion
of the Substitute  Option  Repurchase  Price or the Substitute  Share Repurchase
Price that the Substitute  Option Issuer is not prohibited from delivering;  and
(ii) deliver, as appropriate,  either (A) to the Substitute Option Holder, a new
Substitute  Option  evidencing  the  right of the  Substitute  Option  Holder to
purchase that number of Substitute  Shares obtained by multiplying the number of
Substitute Shares for which the surrendered Substitute Option was exercisable at
the time of delivery of the notice of repurchase by a fraction, the numerator of
which  is the  Substitute  Option  Repurchase  Price  less the  portion  thereof
theretofore  delivered to the  Substitute  Option Holder and the  denominator of
which is the Substitute Option  Repurchase  Price,  and/or (B) to the Substitute
Share  Owner,  a  certificate  for the  Substitute  Option  Shares it is then so
prohibited  from  repurchasing.  If an  Exercise  Termination  Event  shall have
occurred  prior  to the  date of the  notice  by the  Substitute  Option  Issuer
described in the first sentence of this subsection (c), or shall be scheduled to
occur at any time before the  expiration of a period ending on the thirtieth day
after such date, the Substitute Option Holder shall  nevertheless have the right
to exercise the Substitute Option until the expiration of such 30-day period.

         10.      EXTENSION.

         The  time  periods  for the  exercise  of  certain  rights  under  this
Agreement  shall  be  extended:  (i) to  the  extent  necessary  to  obtain  all
governmental  and  regulatory  approvals for the exercise of such rights (for so
long as Holder,  Owner,  Substitute  Option Holder or Substitute Share Owner, as
the case  may be,  is using  commercially  reasonable  efforts  to  obtain  such
regulatory approvals),  and for the expiration of all statutory waiting periods;
(ii) during any period for which an injunction or similar legal  prohibition  on
exercise shall be in effect and (iii) if applicable,  to the extent necessary to
avoid liability under Section 16(b) of the 1934 Act by reason of such exercise.

         11.      REPRESENTATIONS AND WARRANTIES.

         Issuer hereby represents and warrants to Grantee as follows:

                                     - 13 -

<PAGE>



         (a) Issuer  has full  corporate  power and  authority  to  execute  and
deliver this Agreement and to consummate the transactions  contemplated  hereby.
The  execution  and  delivery  of this  Agreement  and the  consummation  of the
transactions  contemplated  hereby have been duly and validly  authorized by the
Board of Directors of Issuer and no other  corporate  proceedings on the part of
Issuer  are  necessary  to  authorize   this  Agreement  or  to  consummate  the
transactions so contemplated.  This Agreement has been duly and validly executed
and delivered by Issuer and constitutes a valid and legally  binding  obligation
of Issuer enforceable in accordance with its terms.

         (b) Issuer has taken all  necessary  corporate  action to authorize and
reserve and to permit it to issue, and at all times from the date hereof through
the  termination  of this  Agreement  in  accordance  with its  terms  will have
reserved  for issuance  upon the  exercise of the Option,  that number of Common
Shares equal to the maximum number of Common Shares at any time and from time to
time issuable  hereunder,  and all such shares,  upon  issuance  pursuant to the
Option, will be duly authorized, validly issued, fully paid, nonassessable,  and
will be delivered free and clear of all claims, liens, encumbrances and security
interests  (other than those created by this  Agreement)  and not subject to any
preemptive rights.

         (c) The execution,  delivery and performance of this Agreement does not
or  will  not,  and  the  consummation  by  Issuer  of any  of the  transactions
contemplated  hereby will not, constitute or result in (i) a breach or violation
of or a default under,  its articles or certificate of incorporation or by-laws,
or the comparable  governing  instruments of any of its subsidiaries,  or (ii) a
breach or violation of or a default under, any agreement, lease, contract, note,
mortgage,  indenture,  arrangement  or  other  obligation  of it or  any  of its
subsidiaries  (with or without the giving of notice,  the lapse of time or both)
or under any law,  rule,  ordinance or  regulation or judgment,  decree,  order,
award or governmental or  non-governmental  permit or licence to which it or any
of its subsidiaries is subject.

         12.      ASSIGNMENT.

         Neither  of  the  parties  hereto  may  assign  any of  its  rights  or
obligations  under this Agreement or the Option  created  hereunder to any other
person,  without the express  written  consent of the other  party,  except that
Grantee may, without the prior written consent of Issuer,  assign the Option, in
whole or in part, to any affiliate of Grantee.

         13.      FILINGS; OTHER ACTIONS.

         Each of  Grantee  and  Issuer  will  use its best  efforts  to make all
filings with,  and to obtain  consents of, all third parties and  regulatory and
governmental  authorities  necessary  to the  consummation  of the  transactions
contemplated  by this  Agreement,  including,  without  limitation,  notices and
filings under the Hart-Scott-Rodino Act.

         14.      TOTAL PROFIT.

         (a) Notwithstanding any other provision of this Agreement,  in no event
shall  Grantee's Total Profit (as  hereinafter  defined) exceed U.S.  $4,700,000
million less the amount of any fee paid  pursuant to Section  10(b) of the Offer
Agreement and, if it otherwise  would exceed such amount,  Grantee,  at its sole
election,  shall either (i) reduce the number of Common  Shares  subject to this
Option,  (ii)  deliver  to Issuer  for  cancellation  Option  Shares  previously
purchased by Grantee,  (iii) pay cash to Issuer or (iv) any combination thereof,
so that  Grantee's  actually  realized Total Profit shall not exceed such amount
after taking into account the foregoing actions.

         (b) Notwithstanding any other provision of this Agreement,  this Option
may not be  exercised  for a  number  of  shares  as  would,  as of the  date of
exercise, result in a Notional Total Profit (as defined below) of more than U.S.
$4,700,000  million less the amount of any fee paid pursuant to Section 10(b) of
the Offer  Agreement;  provided that nothing in this sentence shall restrict any
exercise of the Option permitted hereby on any subsequent date.

         (c) As used herein,  the term "Total  Profit"  shall mean the aggregate
amount  (before  taxes) of the  following:  (i) the amount  received  by Grantee
pursuant to Issuer's  repurchase of the Option (or any portion thereof) pursuant
to Section 7, (ii) (x) the amount  received  by  Grantee  pursuant  to  Issuer's
repurchase of Option Shares  pursuant to Section 7, less (y) Grantee's  purchase
price for such Option Shares, (iii) (x) the net cash amounts received by Grantee
pursuant to the sale of Option Shares (or any other  securities  into which such
Option Shares are converted or  exchanged)  to any  unaffiliated  party with the
prior  written  consent of Issuer,  less (y)  Grantee's  purchase  price of such
Option  Shares,  (iv) any  amounts  received  by Grantee on the  transfer of the
Option (or any portion thereof) to any unaffiliated party with the prior written
consent of Issuer,  and (v) any amount  equivalent to the foregoing with respect
to the Substitute Option.

         (d) As used herein,  the term  "Notional  Total Profit" with respect to
any number of shares as to which  Grantee may  propose to  exercise  this Option
shall be the Total Profit  determined as of the date of such  proposed  exercise
assuming that this Option were  exercised on such date for such number of shares
and assuming  that such shares,  together  with all other Option  Shares (or any
other  securities into which such Option Shares are converted or exchanged) held
by Grantee and its affiliates as of such date, were sold for cash at the closing
market price for the Common  Shares as of the close of business on the preceding
trading day (less customary brokerage commissions).

         (e) Grantee and the Company shall with reasonable diligence do all such
things and provide all such reasonable  further assurances as may be required to
give effect to the intentions of this Section 14, and each of them shall provide
such further documents or instruments required by any other as may be reasonably
necessary or desirable to effect the purpose of this Section 14 and to carry out
its provisions.

         15.      SPECIFIC PERFORMANCE.

         The parties  hereto  acknowledge  that damages  would be an  inadequate
remedy  for a breach of this  Agreement  by  either  party  hereto  and that the
obligations  of the parties  hereto shall be  enforceable by either party hereto
through injunctive or other equitable relief.

         16.      SEVERABILITY.

         If any term,  provision,  covenant  or  restriction  contained  in this
Agreement is held by a court or federal,  state or provincial  regulatory agency
of competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or  invalidated.  If for any reason such court or regulatory  agency  determines
that  Holder  is not  permitted  to  acquire,  or  Issuer  is not  permitted  to
repurchase  pursuant to Section 7, the full number of Common Shares  provided in
Section 1(a) hereof (as adjusted  pursuant to Section 1(b) or Section 5 hereof),
it is the express  intention  of Issuer to allow Holder to acquire or to require
Issuer to repurchase such lesser number of shares as may be permissible, without
any amendment or modification hereof.

         17.      NOTICES.

         All  notices,   requests,  claims,  demands  and  other  communications
hereunder  shall be deemed to have been duly given when delivered in person,  by
fax,  telecopy,  or by registered or certified  mail  (postage  prepaid,  return
receipt requested) at the respective  addresses of the parties and in the manner
set forth in the Offer Agreement.

         18.      GOVERNING LAW.

         This  Agreement  shall be governed by and construed in accordance  with
the laws of the Province of Ontario.  The parties hereto  irrevocably  submit to
the  non-exclusive  jurisdiction  of the  courts of the  Province  of Ontario in
respect of the interpretation and enforcement of this Agreement.

         19.      COUNTERPARTS.

         This  Agreement  may be executed in two or more  counterparts,  each of
which shall be deemed to be an original,  but all of which shall  constitute one
and the same agreement.

         20.      EXPENSES.

         Except as  otherwise  expressly  provided  herein,  each of the parties
hereto shall bear and pay all costs and expenses incurred by it or on its behalf
in connection with the transactions  contemplated hereunder,  including fees and
expenses of its own financial consultants,  investment bankers,  accountants and
counsel.

         21.      ENTIRE AGREEMENT.

         Except  as  otherwise   expressly  provided  herein  or  in  the  Offer
Agreement, this Agreement contains the entire agreement between the parties with
respect to the  transactions  contemplated  hereunder and  supersedes  all prior
arrangements or understandings with respect thereof,  written or oral. The terms
and  conditions of this  Agreement  shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assignees.
Nothing in this Agreement,  expressed or implied, is intended to confer upon any
party, other than the parties hereto, and their respective  successors except as
assignees, any rights,  remedies,  obligations or liabilities under or by reason
of this Agreement, except as expressly provided herein.

of reference  only, do not  constitute  part of this  Agreement and shall not be
deemed to limit or otherwise affect any of the provisions hereof.

         IN WITNESS WHEREOF, each of the parties has caused this Agreement to be
executed on its behalf by its officers thereunto duly authorized,  all as of the
date first above written.
