death or Disability in accordance with the Option Agreement and this Plan, will cease to be exercisable 9 months after the Termination
Date unless otherwise determined by the Board. Any portion of a Participant’s Option that has not vested on or prior to the
date of the Participant’s death or Disability will no longer be exercisable.



4.6.        Option
Agreements



Each Option must be confirmed,
and will be governed, by an Option Agreement signed by the Company and by the Participant, substantially in the form attached as
Schedule 4.6 (Form of Option Agreement).



4.7.        Prohibition
on Transfer of Options



Options are personal
to the Participant. No Participant may deal with an Option or any interest in it or Transfer an Option except in accordance with
this Plan. A purported Transfer of an Option in violation of this Plan will not be valid and the Company will not issue any Share
upon the attempted exercise of that Option. Subject to Law, the Board may establish rules, Regulations and procedures permitting
the Transfer of Options in circumstances and on terms determined by the Board. If Options have been granted to a Participant’s
Subsidiary or a Consultant’s Consultant Entity and the related Subsidiary ceases to be a Subsidiary or the related Consultant
Entity ceases to so qualify, then the Participant will be deemed to have Transferred any Option held by that entity to the entity,
and that Transfer will be subject to the requirements and sanctions set out in this section. Notwithstanding anything to the contrary
in the Plan, Options cannot be Transferred other than by will or the laws of descent and distribution and will be exercisable during
a Participant’s lifetime only by the Participant.



ARTICLE 5.
EXERCISE OF OPTIONS



5.1.        Method
of Exercise of Option



A Participant may exercise
all or a portion of an Option by delivering to the Company, to the address and person set out in section 10.1, a completed
exercise form in the form attached as Schedule 5.1 (Exercise Form) and, if exercised under section 5.2, accompanied by
payment of the exercise price multiplied by the number of Shares to be purchased.



5.2.        Payment
of Option Price



The purchase price of
each Share purchased under an Option must be paid in full at the time of exercise by bank draft, certified cheque or in any other
manner permitted by the Board and by Law. Upon receipt of payment in full, but subject to this Plan, the number of Shares in respect
of which the Option is exercised will be issued as fully paid and non-assessable.

5.3.        Withholding
of Tax



5.3.1.          If

a condition of issuing the Shares or at any other later date, (1) require the Participant exercising the Option to pay to
the Company, in addition to and in the same manner as the exercise price for the Shares, (2) withhold from any other amounts
payable by the Company to the Participant or (3) transfer from the Participant to the Company Shares issuable upon exercise
of the Option having a Fair Value equal to, any amount that the Company is obliged to remit to that taxing authority in respect
of the exercise of the Option or the sale of the Shares acquired on exercise of the Option. Any additional payment will, in any
event, be due no later than the date as of which any amount with respect to the Option exercised must be included in the gross
income of the Participant for tax purposes.



5.3.2.          Promptly

date and terms of the sale and will provide all other information regarding the sale as the Company may reasonably require.

or Sale of the Company



If there is:



7.1.1.      a
Combination,

7.1.3.      a
reorganization or liquidation of the Company,



the Board, or the board
of directors of any entity assuming the obligations of the Company, having regard to its fiduciary duties and the best interests
of the Company, will, as to unexercised Options, upon written notice to Participants, provide that: (a) all unvested Options of
Executives will vest immediately; (b) all unexercised Options (both vested and unvested) will terminate immediately prior to the
consummation of the merger, consolidation, acquisition, reorganization, liquidation, sale or transfer unless those Options which

Options upon Acquisition by the Company

Options under the Plan in substitution for options held by directors, officers or employees of or consultants to another entity

a result of the acquisition by the Company of property or securities of the other entity. The Company may direct that substitute

Board will, subject to Law, make a substitution or adjustment in

maximum number and/or class of securities of the Company reserved for issuance under this Plan; or

number and/or class of securities of the Company subject to unexercised Options previously granted,



as the Board determines is appropriate in the circumstances.



ARTICLE 8.
Employment and Compensation



8.1.       No
Special Employment Rights



Nothing contained in
the Plan or in any Option will confer upon any Participant any right with respect to the continuation of the Participant’s
appointment, employment or engagement by the Company or interfere in any way with the right of the Company at any time to terminate
or change any terms of that appointment, employment or engagement including any increase or decrease in the compensation of the
Participant.



8.2.       Other
Employee Benefits



The amount of any compensation
deemed to be received by a Participant as a result of the exercise of an Option or the sale of Shares received upon an exercise
of an Option will not constitute compensation for the purpose of determining any other employee benefits of that Participant, including
benefits under any bonus, pension, profit-sharing, life insurance or salary continuation plan, except as otherwise specifically
determined by the Board.

8.3.       Non-Exclusivity

remains outstanding. However, notwithstanding the termination of this Plan, the Board may make any amendments to this Plan, or
to any outstanding Option, that it would be entitled to make if this Plan were still in effect.



9.2.       Amendment
With Individual Consent



With the consent of the
affected Participant, the Board may amend any outstanding Option in any manner to the extent that the Board would have had the

Section
2.
Awards Under the Plan



| | 2.1. | Payment and Deferral of Eligible Remuneration
| | ---- | ---------------------------------------------



Subject to any rules,
approvals and conditions that the Committee may impose, a Participant may, with the consent of the Committee from time to time,
elect to receive Eligible Remuneration, in whole or in part, in the form of Deferred Share Units.



| | 2.2. | Method of Electing
| | ---- | ------------------



2.2.1.     To
elect a form or forms of payment of Eligible Remuneration for the period from June 1, 1999 to May 31, 2000 pursuant to the Plan,
a Participant will, no later than May 5, 2000, complete and deliver to the Secretary of the Corporation a written election in the
form prescribed by the Secretary.



2.2.2.     To
elect a form or forms of payment of Eligible Remuneration for any subsequent fiscal year during which the Plan is in effect and
in respect of which the Eligible Remuneration will become payable, a Participant shall no later than ten days before the end of
a fiscal year complete and deliver to the Secretary of the Corporation a written election for the immediately following fiscal
year in the form attached as Appendix A hereto subject to any changes in such form made by the Committee from time to time.



2.2.3.     The
Participant’s written election will designate the percentage of each item of the Eligible Remuneration for the applicable
fiscal year that the Participant elects to receive in the form of Deferred Share Units and the percentage that the Participant
elects to receive in Shares and/or cash.



- 3 -







2.2.4.     In
the absence of a designation to the contrary, subject to the approval of the Committee, the Participant’s election for the
latest fiscal year with respect to those percentages will continue to apply to all subsequent Eligible Remuneration payments until
the Participant submits another written election in accordance with this section.



2.2.5.     A
Participant will file only one election in respect of the Eligible Remuneration payable in respect of any fiscal year and the election
will be irrevocable for that year. If no election is filed by a Participant, and no prior election remains effective, the Participant
will be deemed to have elected to be paid other than in Deferred Share Units all Eligible Remuneration payable to that Participant
for the applicable fiscal year.



| | 2.3. | Payment of Eligible Remuneration
| | ---- | --------------------------------



Eligible Remuneration
will be paid in Shares or cash, or up to a percentage of such Eligible Remuneration as is established by the Committee, credited
as Deferred Share Units, as elected by the Participant, on a periodic instalment basis as established by the Committee.



| | 2.4. | Deferred Share Units
| | ---- | --------------------



Where a Participant
has elected and is entitled to receive Deferred Share Units, such Deferred Share Units will be credited to an account maintained
for the Participant by the Corporation. The number of Deferred Share Units (including fractional Deferred Share Units, computed
to three digits) to be credited on each of the dates established by the Committee pursuant to section 2.3 will be determined
by dividing the amount of the Eligible Remuneration that is to be paid in the form of Deferred Share Units on that date by the
Fair Market Value per Share on that date.



| | 2.5. | Dividend Equivalents
| | ---- | --------------------



On any date on which
a dividend is paid on Shares, a Participant’s account will be credited with the number of Deferred Share Units (including
fractional Deferred Share Units, computed to three digits) calculated by (i) multiplying the amount of the dividend per Share
by the aggregate number of Deferred Share Units that were credited to the Participant’s account as of the record date for
payment of the dividend, and (ii) dividing the amount obtained in (i) by the Fair Market Value per Share on the date
on which the dividend is paid.



| | 2.6. | Participant’s Account
| | ---- | ---------------------



A written confirmation
of the balance in each Participant’s account will be sent by the Corporation to the Participant upon request of the Participant.



| | 2.7. | Adjustments and Reorganizations
| | ---- | -------------------------------



In the event of any
stock dividend, stock split, combination or exchange of shares, merger, consolidation, spin-off or other distribution (other than
normal cash dividends) of Corporation assets to shareholders, or any other change in the capital of the Corporation affecting Shares,
the Committee, in its discretion, will make, with respect to the number of Deferred Share Units outstanding under the Plan, any
proportionate adjustments as it considers appropriate to reflect that change.

| | 2.8. | Cessation of Service
| | ---- | --------------------



| | 2.8.1. | Termination of Service
| | ------ | ----------------------



2.8.1.1.              A
Participant who has Terminated Service may redeem the Deferred Share Units credited to the Participant’s account by filing
with the Secretary of the Corporation a notice of redemption of the Deferred Share Units in the prescribed form on or before March
15 of the first calendar year commencing after the date the Participant Terminated Service. If the Participant fails to file a
notice of redemption of the Deferred Share Units on or before that date, the Participant will be deemed to have filed with the
Secretary of the Corporation a notice of redemption on that date. The date on which a notice of redemption is filed or deemed to
be filed with the Secretary of the Corporation is the “Filing Date”.



2.8.1.2.              The
notice of redemption filed by the Participant will specify that the Participant wishes to receive either: (i) a lump sum cash
payment (net of any applicable withholdings) equal to the number of Deferred Share Units credited to the Participant’s account
as of the Filing Date multiplied by the Fair Market Value per Share on the Filing Date (the “Final Payment”); or (ii) that
number of Shares that is equal to the number of Deferred Share Units credited to the Participant’s account as of the Filing
Date. The Participant may request on the notice of redemption that the Participant receive a percentage of the Final Payment in
cash and the remaining percentage of the Final Payment in Shares, in either case in accordance with the preceding sentence as appropriately
amended. If a notice of redemption is deemed to be filed or the notice of redemption filed does not request receipt of cash or
Shares, the Participant will be deemed to have requested to receive the entire Final Payment in cash.



2.8.1.3              The
requests of a Participant referred to in paragraph 2.8.1.2 above are subject to the approval of the Committee, and the Committee
will determine, in its sole discretion, what portion of the Final Payment is to be paid to the Participant in cash and what portion
is to be paid in Shares. The Committee will further determine whether payment in Shares will be made by the issuance of Shares
from treasury or through the Corporation contributing all or a Portion of the Final Payment to a Trustee to be used by the Trustee
to purchase Shares on the TSX.



2.8.1.4              Within
seven days following the Filing Date, the Corporation will if the Participant is to receive all or a portion of the Final Payment
in cash, make that payment to the Participant in cash. Within ten (10) business days following the Filing Date, if the Participant
is to receive Shares, the Corporation may, at its discretion, elect to issue Shares from treasury equal to the number of Deferred
Share Units credited to the Participant’s account as of the relevant redemption date or contribute all or the appropriate
portion of the Final Payment to the Trustee and require the Trustee to use that amount as soon as practicable thereafter to purchase
Shares on the TSX and deliver those Shares to the Participant. An amount that would otherwise give rise to fractional Shares will
be paid in cash.



- 5 -







2.8.1.5              For
greater certainty, if a Participant who would otherwise receive Shares is a citizen or resident of a country other than Canada,
the Corporation has the right, in its sole discretion, to pay entirely in cash the Final Payment, should the Corporation determine
that the regulatory or other requirements of the applicable foreign jurisdiction associated with the purchase of Shares are too
onerous to it or the Participant.



2.8.2.     Death
of Participant. In the event of the death of a Participant, the Corporation will make Final Payment, within ninety days after
the Participant’s death, through either: (i) a lump sum cash payment; (ii) an issuance of Shares from treasury or (iii) a
combination of a lump cash payment and issuance of Shares, to or for the benefit of the legal representative of the Participant.
The Committee will determine, in its sole discretion, what portion of the Final Payment is to be paid to the Participant in cash
and what portion is to be paid in Shares. The lump sum cash payment will equal the number of Deferred Share Units credited to the
Participant’s account on the date of payment multiplied by the Fair Market Value per Share determined as of the date that
is five days before the date of payment. The Shares issued from treasury will equal the number of Deferred Share Units credited
to the Participant’s account as of the date of payment.



2.8.3.     Death
of Participant after Termination of Service. If a Participant dies after the Participant has Terminated Service but before
filing a notice of redemption with the Secretary of the Corporation, section 2.8.2 will apply provided that, in no event will
payment or the issuance of Shares be made later than December 31 of the first calendar year commencing after the Participant
has Terminated Service.



2.8.4.     Termination
With Cause. A Participant who has been terminated with cause may not redeem the Deferred Share Units held by that Participant
and those Deferred Share Units so held will be deemed cancelled as of the date of termination of the Participant.

securities and tax law requirements, but no amendment will, without the consent of the Participant or unless required by law, adversely
affect the rights of a Participant with respect to Deferred Share Units that have been credited to the account of the Participant
at the time of such amendment to the Plan.



3.6.2.	    Notwithstanding section
3.6.1, the Board must obtain shareholder approval for the following amendments to the Plan:



| | (a) | an increase to the maximum number of securities reserved for issuance under the Plan or any other
security based compensation arrangement; and

| | (b) | amendments to this section 3.6.
| | --- | -------------------------------



| | 3.7. | Plan Termination

The Board may terminate
the Plan at any time, but no termination will, without the consent of a Participant or unless required by law, adversely affect

the time of such termination of the Plan.
