have been surrendered without being exercised in full shall again be available
for issuance under this Plan.

5.       OPTIONS

         The Committee may, from time to time and upon such terms and conditions
as it may determine, authorize the granting to Participants of Options provided,
however, that: (i) at no time shall the number of Common Shares reserved for
issuance to any one Participant under the Plan or any other share compensation
arrangement exceed 5% of the outstanding issue of Common Shares; (ii) at no time
shall the number of Common Shares reserved for issuance pursuant to stock
options granted to "insiders" (as that term is defined in Section 627 of The
Toronto Stock Exchange Company Manual) exceed 10% of the outstanding issue of
Common Shares; (iii) under no circumstances shall insiders be issued in excess
of 10% of the outstanding issue of Common shares within any one-year period
pursuant to the exercise of Options granted under the Plan or any other share
compensation arrangement; and (iv) under no circumstances shall any one insider
and that insider's associates be issued in excess of 5% of the outstanding issue
of Common Shares within any one-year period pursuant to the exercise of Options
granted under the Plan or any other share compensation arrangement.

6.       AGREEMENT

         The terms and conditions of each Option shall be embodied in a written
agreement (the "Agreement") in a form approved by the Committee which shall
contain terms and conditions not inconsistent with the Plan and which shall
incorporate the Plan by reference. Options granted under the Plan shall comply
with the following terms and conditions:

         (i)      Each Agreement shall specify the number of Common Shares for
which Options have been granted.

         (ii) Each Agreement shall specify the Option Price, which shall not be
less than 100% of the Fair Market Value per Common Share on the Date of Grant.

         (iii) Each Agreement shall specify that the Option Price shall be
payable (a) in cash or by cheque acceptable to the Company, (b) by the transfer
to the Company of Common Shares having an aggregate Fair Market Value per Common
Share at the date of exercise equal to the aggregate Option Price or (c) by a
combination of such methods of payment.

         (iv) Successive grants may be made to the same Participant whether or
not any Options previously granted to such Participant remain unexercised.

         (v) Each Agreement shall specify the applicable vesting schedule and
the effective term of the Option. In the event of a termination of a
Participant's employment by reason of death or Permanent Disability, 50% of such
Participant's Options shall become Vested Options if such Options were less than
50% vested at the time of such termination.

         (vi) Options granted under the Plan are not intended to qualify as
"incentive stock options" within the meaning of Section 422A of the Code.

         (vii) No Option shall be exercisable more than ten years from the date
of Grant.

         (viii) Each Option granted under the Plan shall be subject to such
additional terms and conditions, not inconsistent with the Plan, which are
prescribed by the Committee and set forth in the applicable Agreement.

         (ix) As soon as practicable following the exercise of any Options, a
certificate evidencing the number of Common Shares issued in connection with
such exercise shall be issued in the name of the Participant or as the
Participant shall otherwise, in writing, direct.

7.       TERMINATION OF EMPLOYMENT, CONSULTING AGREEMENT OR TERM OF OFFICE

         (a) In the event that a Participant's employment, consulting
arrangement or term of office with the Company or one of its Subsidiaries
terminates for any reason, unless the Committee or the Board determines
otherwise, any Options which have not become Vested Options shall terminate and
be cancelled without any consideration being paid therefor.

         (b) In the event that a Participant's employment with the Company or
one of its Subsidiaries is terminated without Cause, or the Participant's
employment is terminated by reason of the Participant's voluntary resignation
(including by reason of retirement), death or Permanent Disability, or upon the
termination of a Participants' consulting arrangement or term of office, the
Participant (or the Participant's estate) shall be entitled to exercise the
Participant's Options which have become Vested Options as of the date of
termination for a period of 30 days, or such longer period as the Committee or
the Board determines, following the date of termination.

         (c) In the event that a Participant's employment, consulting
arrangement or term of office with the Company or one of its Subsidiaries is
terminated for Cause, such Participant's Vested Options shall terminate and be
cancelled without any consideration being paid therefor.

8.       TRANSFERABILITY

         No Option shall be transferable by a Participant other than by will or
the laws of descent and distribution, provided, however, that Options may be
transferred if approved by the Committee or the Board and by any regulatory
authority having jurisdiction or stock exchange on which the common shares
subject to Options are listed. Options shall be exercisable during the
Participant's lifetime only by the Participant or by the Participant's guardian
or legal representative.

9.       ADJUSTMENTS

         The Committee may make or provide for such adjustments in the maximum
number of Common Shares specified in Paragraph 4, in the number of Common Shares
covered by outstanding Options granted hereunder, and/or in the Option Price
applicable to such Options as the Committee in its sole discretion may determine
is equitably required to prevent dilution or enlargement of the rights of
Participants that otherwise would result from any stock dividend, stock split,
combination of shares, recapitalization or other change in the capital structure
of the Company, merger, consolidation, spin-off, reorganization, partial or
complete liquidation, issuance of rights or warrants to purchase securities or
any other corporate transaction or event having an effect similar to any of the
foregoing.

10.      FRACTIONAL SHARES

         The Company shall not be required to issue any fractional Common Shares
pursuant to the Plan. The Committee may provide for the elimination of fractions
or for the settlement of fractions in cash.

11.      WITHHOLDING TAXES

         The Company and its Subsidiaries shall have the right to require any
individual entitled to receive Common Shares pursuant to an Option to remit to
the Company, prior to the delivery of any certificates evidencing such shares,
any amount sufficient to satisfy any Canadian or United States federal, state,
provincial or local tax withholding requirements. Prior to the Company's
determination of such withholding liability, such individual may make an
irrevocable election to satisfy, in whole or in part, such obligation to remit
taxes by directing the Company to withhold Common Shares that would otherwise be
received by such individual. Such election may be denied by the Committee in its
discretion, or may be made subject to certain conditions specified by the
Committee, including, without limitation, conditions intended to avoid the
imposition of liability against the individual under Section 16(b) of the
Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder.

12.      REGISTRATION RESTRICTIONS

         An Option shall not be exercisable unless and until (i) a registration
statement under the Securities Act of 1933, as amended, has been duly filed and
declared effective pertaining to the Common Shares subject to such Option, such
Common Shares shall have been qualified under applicable state "blue sky" laws
and the Company has been a "reporting issuer" for purposes of the Ontario
Securities Act in good standing for not less than twelve months, or (ii) the
Committee, in its sole discretion determines that such registration,
qualification and status is not required as a result of the availability of an
exemption from such registration, qualification, and status under such laws.

13.      SHAREHOLDER RIGHTS

         A Participant shall have no rights as a shareholder with respect to any
Common Shares issuable upon exercise of an Option until a certificate or
certificates evidencing such shares shall have been issued to such Participant,
and no adjustment shall be made for dividends or distributions or other rights
in respect of any share for which the record date is prior to the date upon
which the Participant shall become the holder of record thereof.

14.      BREACH OF RESTRICTIVE COVENANTS

         If (i) a Participant is a party to an employment agreement with the
Company or any of its Subsidiaries or affiliates and (ii) such Participant
materially breaches any of the restrictive covenants set forth in such
employment agreement (including, without limitation, any restrictive covenants
relating to non-competition, non-solicitation or confidentiality), then all of
such Participant's Options (whether or not Vested Options) shall terminate and
be cancelled without consideration being paid therefor.

15.      AMENDMENTS, ETC.

         (a) The Board may at any time and from time to time alter, amend,
suspend or terminate the Plan in whole or in part, and the Committee may,
subject to applicable legal requirements at any time and from time to time waive
any provision of any Option or Agreement; provided, however, that no termination
or amendment of the Plan or any waiver of any provision of any Option or
Agreement may, without the consent of the Participant to whom any Award shall
previously have been granted, adversely affect the rights of such Participant in
such Award; provided further, however that amendments shall be subject to (x)
the approval of a majority of the Common Shares entitled to vote if the
Committee determines that such approval is necessary in order for the Company to
rely on the exemptive relief provided under Rule 16b-3




<PAGE>   7

and (y) all other approvals, whether regulatory, shareholder or otherwise, which
are required by law, The Toronto Stock Exchange or any other applicable
securities exchange.

         (b) The Plan shall not confer upon a Participant any right with respect
to continuance of employment or other service with the Company or any
Subsidiary, nor will it interfere in any way with any right the Company or any
Subsidiary would otherwise have to terminate such Participant's employment or
other service at any time.

16.      EFFECTIVE DATE

         The Plan shall be effective as of June 7, 1999.

17.      GOVERNING LAW

         The Plan and all rights hereunder shall be construed in accordance with
and governed by the laws of the Province of Ontario and the laws of Canada
applicable therein.
