cancelled, expired or otherwise terminated for any reason whatsoever, as the case may be, will ipso facto again be immediately available for purchase pursuant to Awards granted under this Plan.

All grants of Awards under this Plan will be evidenced by Award Agreements. Award Agreements will be subject to the applicable provisions of
this Plan and will contain such provisions as are required by this Plan and any other provisions that the Board may direct. Any one officer of the Corporation is authorized and empowered to execute and deliver, for and on behalf of the Corporation,
an Award Agreement to each Participant granted an Award pursuant to this Plan.



|3.7 | Non-transferability of Awards
|--- | -----------------------------

No assignment or transfer of Awards, whether voluntary, involuntary, by operation of law or otherwise, vests any interest or right in such
Awards whatsoever in any assignee or transferee (except that, if, and for so long as the Shares are listed on the TSX, a Participant may transfer Awards to Permitted Assigns in a manner consistent with applicable tax and securities laws) and
immediately upon any assignment or transfer, or any attempt to make the same, such Awards will terminate and be of no further force or effect. If any Participant has transferred Awards to a corporation pursuant to this Section 3.7, such Awards
will terminate and be of no further force or effect if at any time the transferor should cease to own all of the issued shares of such corporation.



|3.8 | Dividend Equivalents
|--- | --------------------



| | (a) | RSUs, PSUs and DSUs shall be credited with dividend equivalents in the form of additional RSUs, PSUs and DSUs
as of each dividend payment date in respect of which normal cash dividends are paid on Shares. Such dividend equivalents shall be computed by dividing: (a) the amount obtained by multiplying the amount of the dividend declared and paid per
Share by the number of RSUs, PSUs and DSUs held by the Participant on the record date for the payment of such dividend,
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

date, with fractions computed to three decimal places. Dividend equivalents credited to a Participants accounts shall vest in proportion to the RSUs, PSUs and DSUs to which they relate.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | The Board may in its discretion include in an Award Agreement applicable to an Other Share-Based Award a
dividend equivalent right entitling the Participant to receive amounts equal to the normal cash dividends that would be paid, during the time such Award is outstanding and unexercised, on the Shares covered by such Award if such Shares were then
outstanding and may decide whether such payments shall be made in cash, in Shares or in another form, whether they shall be conditioned upon the vesting of the Award to which they relate, the time or times at which they shall be made, and such other
terms and conditions as the Board shall deem appropriate.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | The foregoing does not obligate the Corporation to make dividends on Shares and nothing in this Plan shall be
interpreted as creating such an obligation.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------



|3.9 | Permitted Assigns
|--- | -----------------

If, and for so long as the Shares are listed on the TSX, grants of Awards may be made to Permitted Assigns of Employees, Directors and
Consultants and may be transferred by Employees, Directors and Consultants to a Permitted Assign of an Employee, Director or Consultant as applicable, except for U.S. Taxpayers, if transfer to a Permitted Assign would be prohibited by
Section 409A of the Code. In any such case, the provisions of ARTICLE 10 shall apply to the Award as if the Award was held by the Employee, Director or Consultant rather than such persons Permitted Assign.

In the event of the death of the Permitted Assign, the Award shall be automatically transferred to the Employee, Director or Consultant who
effected the transfer of the Award to the deceased Permitted Assign.

ARTICLE 12

SHARE CAPITAL ADJUSTMENTS



|12.1 | General
|---- | -------

The existence of any Awards does not affect in any way the right or power of the Corporation or its shareholders to make, authorize or
determine any adjustment, recapitalization, reorganization or any other change in the Corporations capital structure or its business, or any amalgamation, combination, arrangement, merger or consolidation involving the Corporation, to create
or issue any bonds, debentures, Shares or other securities of the Corporation or to determine the rights and conditions attaching thereto, to effect the dissolution or liquidation of the Corporation or any sale or transfer of all or any part of its
assets or business, or to effect any other corporate act or proceeding, whether of a similar character or otherwise, whether or not any such action referred to in this Section would have an adverse effect on this Plan or on any Award granted
hereunder.



|12.2 | Reorganization of Corporations Capital
|---- | ---------------------------------------

Should the Corporation effect a subdivision or consolidation of Shares or any similar capital reorganization or a payment of a stock dividend
(other than a stock dividend that is in lieu of a cash dividend), or should any other change be made in the capitalization of the Corporation that does not constitute a Change in Control and that would warrant the amendment or replacement of any
existing Awards in order to adjust the number of Shares that may be acquired on the vesting of outstanding Awards and/or the terms of any Award in order to preserve proportionately the rights and obligations of the Participants holding such Awards,
the Board will, subject to the prior approval of the Exchange, authorize such steps to be taken as it may consider to be equitable and appropriate to that end.



|12.3 | Other Events Affecting the Corporation
|---- | --------------------------------------

In the event of an amalgamation, combination, arrangement, merger or other transaction or reorganization involving the Corporation and
occurring by exchange of Shares, by sale or lease of assets or otherwise, that does not constitute a Change in Control and that warrants the amendment or replacement of any existing Awards in order to adjust: (a) the number of Shares that may
be acquired on the vesting of outstanding Awards and/or (b) the terms of any Award in order to preserve proportionately the rights and obligations of the Participants holding such Awards, the Board will, subject to the prior approval of the
Exchange, authorize such steps to be taken as it may consider to be equitable and appropriate to that end.



|12.4 | Immediate Acceleration of Awards
|---- | --------------------------------

Where the Board determines that the steps provided in Sections 12.2 and 12.3 would not preserve proportionately the rights, value and
obligations of the Participants holding such Awards in the circumstances or otherwise determines that it is appropriate the Board may permit the immediate vesting of any unvested Awards and immediate lapse of any Restricted Period.



|12.5 | Issue by Corporation of Additional Shares
|---- | -----------------------------------------

Except as expressly provided in this ARTICLE 12, neither the issue by the Corporation of shares of any class or securities convertible into or
exchangeable for shares of any class, nor the



---



- 20 -



conversion or exchange of such shares or securities, affects, and no adjustment by reason thereof
is to be made with respect to the number of Shares that may be acquired as a result of a grant of Awards.



|12.6 | Fractions
|---- | ---------

No fractional Shares will be issued pursuant to an Award. Accordingly, if, as a result of any adjustment under Section 12.2, 12.3 or
dividend equivalent, a Participant would become entitled to a fractional Share, the Participant has the right to acquire only the adjusted number of full Shares and no payment or other adjustment will be made with respect to the fractional Shares,
which shall be disregarded.

ARTICLE 13

MISCELLANEOUS PROVISIONS



|13.1 | Legal Requirement
|---- | -----------------

The Corporation is not obligated to grant any Awards, issue any Shares or other securities, make any payments or take any other action if, in
the opinion of the Board, in its sole discretion, such action would constitute a violation by a Participant, Director or the Corporation of any provision of any applicable statutory or regulatory enactment of any government or government agency or
the requirements of any stock exchange upon which the Shares may then be listed.



|13.2 | Participants Entitlement
|---- | -------------------------

Except as otherwise provided in this Plan, Awards previously granted under this Plan are not affected by any change in the relationship
between, or ownership of, the Corporation and an Affiliate. For greater certainty, all grants of Awards remain are not affected by reason only that, at any time, an Affiliate ceases to be an Affiliate.



|13.3 | Withholding Taxes
|---- | -----------------

The granting or vesting or lapse of the Restricted Period of each Award under this Plan is subject to the condition that if at any time the
Board determines, in its discretion, that the satisfaction of withholding tax or other withholding liabilities is necessary or desirable in respect of such grant, vesting or lapse of the Restricted Period, such action is not effective unless such
withholding has been effected to the satisfaction of the Board. In such circumstances, the Board may require that a Participant pay to the Corporation such amount as the Corporation or an Affiliate is obliged to remit to the relevant taxing
authority in respect of the granting or vesting or lapse of the Restricted Period of the Award. Any such additional payment is due no later than the date on which any amount with respect to the Award is required to be remitted to the relevant tax
authority by the Corporation or an Affiliate, as the case may be.



|13.4 | Rights of Participant
|---- | ---------------------

No Participant has any claim or right to be granted an Award and the granting of any Award is not to be construed as giving a Participant a
right to remain as an employee, consultant or director of the Corporation or an Affiliate. No Participant has any rights as a shareholder of the



---



- 21 -



Corporation in respect of Shares issuable pursuant to any Award until the allotment and issuance
to such Participant, or as such Participant may direct, of certificates representing such Shares.



|13.5 | Other Incentive Awards
|---- | ----------------------

The Board shall have the right to grant other incentive awards based upon Shares under this Plan to Participants in accordance with applicable
laws and regulations and subject to regulatory approval, including without limitation the approval of the Exchange (to the extent the Corporation has any securities listed on the particular exchange), having such terms and conditions as the Board
may determine, including without limitation the grant of Shares based upon certain conditions and the grant of securities convertible into Shares.



|13.6 | Blackout Period
|---- | ---------------

If an Award expires during, or within five business days after, a trading black-out period imposed by the Corporation to restrict trades in
the Corporations securities, then, notwithstanding any other provision of this Plan, the Award shall expire ten business days after the trading black-out period is lifted by the Corporation.



|13.7 | Termination
|---- | -----------

The Board may, without notice or shareholder approval, terminate the Plan on or after the date upon which no Awards remain outstanding.



|13.8 | Amendment
|---- | ---------



| | (a) | Subject to the rules and policies of any stock Exchange on which the Shares are listed and applicable law, the
Board may, without notice or shareholder approval, at any time or from time to time, amend the Plan for the purposes of:

| | (i) | making any amendments to the general vesting provisions or Restricted Period of each Award;
| | --- | -------------------------------------------------------------------------------------------



| | (ii) | making any amendments to the provisions set out in ARTICLE 10;
| | ---- | --------------------------------------------------------------



| | (iii) | making any amendments to add covenants of the Corporation for the protection of Participants, as the case may
be, provided that the Board shall be of the good faith opinion that such additions will not be prejudicial to the rights or interests of the Participants, as the case may be;
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | making any amendments not inconsistent with the Plan as may be necessary or desirable with respect to matters
or questions which, in the good faith opinion of the Board, having in mind the best interests of the Participants and Directors, it may be expedient to make, including amendments that are desirable as a result of changes in law in any jurisdiction
where a Participant resides, provided that the Board shall be of the opinion that such amendments and modifications will not be prejudicial to the interests of the Participants and Directors; or
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---



- 22 -



| | (v) | making such changes or corrections which, on the advice of counsel to the Corporation, are required for the
purpose of curing or correcting any ambiguity or defect or inconsistent provision or clerical omission or mistake or manifest error, provided that the Board shall be of the opinion that such changes or corrections will not be prejudicial to the
rights and interests of the Participants.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Subject to Section 11.1, the Board shall not materially adversely alter or impair any rights or increase
any obligations with respect to an Award previously granted under the Plan without the consent of the Participant, as the case may be.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Notwithstanding any other provision of this Plan, none of the following amendments shall be made to this Plan
without approval of the Exchange (to the extent the Corporation has any securities listed on the particular Exchange) and the approval of shareholders in accordance with the requirements of such Exchange(s):
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | amendments to the Plan which would increase the number of Shares issuable under the Plan, except as otherwise
provided pursuant to the provisions in the Plan, including Sections 12.2 and 12.3, which permit the Board to make adjustments in the event of transactions affecting the Corporation or its capital;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | amendments to the Plan which would increase the number of Shares issuable to Insiders, except as otherwise
provided pursuant to the provisions in the Plan, including Sections 12.2 and 12.3, which permit the Board to make adjustments in the event of transactions affecting the Corporation or its capital; and
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | amendments to this Section 13.8.
| | ----- | --------------------------------

Any amendment that would cause an Award held by a U.S. Taxpayer to fail to comply with Section 409A of the Code shall be null and
void ab initio.



|13.9 | Section 409A of the Code
|---- | ------------------------

This Plan will be construed and interpreted to be exempt from, or where not so exempt, to comply with Section 409A of the Code to the
extent required to preserve the intended tax consequences of this Plan. The Corporation reserves the right to amend this Plan to the extent it reasonably determines is necessary in order to preserve the intended tax consequences of this Plan in
light of Section 409A of the Code and any regulations or guidance under that section. In no event will the Corporation be responsible if Awards under this Plan result in adverse tax consequences to a U.S. Taxpayer under Section 409A of the
Code. Notwithstanding any provisions of the Plan to the contrary, in the case of any specified employee within the meaning of Section 409A of the Code who is a U.S. Taxpayer, distributions of non-qualified deferred compensation
under Section 409A of the Code made in connection with a separation from service within the meaning set forth in Section 409A of the Code may not be made prior to the date which is 6 months after the date of separation
from service (or, if earlier, the date of death of the U.S. Taxpayer). Any amounts subject to a delay in payment pursuant to the



---



- 23 -



preceding sentence shall be paid as soon practicable following such 6-month anniversary of such
separation from service.



|13.10 | Requirement of Notification of Election Under Section 83(b) of the Code
|----- | -----------------------------------------------------------------------

If a Participant, in connection with the acquisition of Restricted Shares under the Plan, is permitted under the terms of the Award Agreement
to make the election permitted under Section 83(b) of the Code (i.e., an election to include in gross income in the year of transfer the amounts specified in Section 83(b) of the Code notwithstanding the continuing transfer restrictions)
and the Participant makes such an election, the Participant shall notify the Corporation of such election within ten (10) days of filing notice of the election with the Internal Revenue Service, in addition to any filing and notification
required pursuant to regulations issued under Section 83(b) of the Code.



|13.11 | Indemnification
|----- | ---------------

Every member of the Board will at all times be indemnified and saved harmless by the Corporation from and against all costs, charges and
expenses whatsoever including any income tax liability arising from any such indemnification, that such member may sustain or incur by reason of any action, suit or proceeding, taken or threatened against the member, otherwise than by the
Corporation, for or in respect of any act done or omitted by the member in respect of this Plan, such costs, charges and expenses to include any amount paid to settle such action, suit or proceeding or in satisfaction of any judgment rendered
therein.



|13.12 | Participation in the Plan
|----- | -------------------------
