In the event that the Common Shares shall be subdivided or

in Section 5.1, in the number or kind of outstanding Common Shares or of any

or for which they shall have been exchanged, pursuant to a Reorganization or
otherwise, then there shall be substituted for each Common  Share referred
to in the Plan or for each share into which such Common Share shall have been so
changed or exchanged, the kind of securities into which each outstanding Common
Share shall be so changed or exchanged and an equitable adjustment shall be
made, if required, in the number of DSUs then recorded in the Directors
Account, such adjustment, if any, to be reasonably determined by the Committee
and to be effective and binding for all purposes.

Plan may be amended, suspended or terminated at any time by the Board in whole

|7.2 | Plan Termination
|--- | ----------------

---

- 9 -

The Committee may decide to discontinue granting awards under
the Plan at any time in which case no further Deferred Share Units shall be
awarded or credited under the Plan. Any Deferred Share Units which remain
outstanding in a Participants Account at that time shall continue to be dealt
with according to the terms of the Plan. The Plan shall terminate when all
payments owing pursuant to Section 4.2 of the Plan have been made and all
Deferred Share Units have been cancelled in all Participants Accounts.

|8.  | GENERAL PROVISIONS
|--- | ------------------
|    |                   
|8.1 | Withholding       

The Corporation shall not have any responsibility for or in
respect of the tax consequences of a grant of Deferred Share Units to, or the
receipt of Deferred Share Units or payout in respect thereof by, Participants
under this Plan. The Corporation may withhold from any amount payable to a
Participant, either under this Plan, or otherwise, such amount as may be
necessary or desirable as determined by the Corporation in its sole discretion
so as to ensure that the Corporation will be able to comply with the applicable
provisions of any federal, provincial, state or local law relating to the
withholding or remittance of tax or other required deductions or amounts,
including on the amount, if any, includable in the income of a Participant. The
Corporation shall also have the right in its discretion to satisfy any such
withholding tax liability by retaining, acquiring or selling (on such terms as
the Corporation determines in its sole discretion, and, in the case of a sale,
without any requirement to obtain the best possible price) on behalf of a
Participant any Common Shares which would otherwise be issued or provided to a
Participant hereunder, or to require a Participant, as a condition of receiving
anything under this Plan, to deliver cash or certified cheque payable to the
Corporation for the amount of applicable tax as determined by the Corporation in
its sole discretion.

|8.2 | Assignability
|--- | -------------

No right to receive payment of DSUs and other benefits under
the Plan shall be transferable or assignable by a Participant except by will or
laws of descent and distribution.

|8.3 | Unfunded Plan
|--- | -------------

Unless otherwise determined by the Committee, the Plan shall be
unfunded. To the extent any Participant or his or her estate holds any rights by
virtue of a grant of Deferred Share Units under the Plan, such rights (unless
otherwise determined by the Committee) shall be no greater than the rights of an
unsecured creditor of the Corporation.

|8.4 | Final Determination
|--- | -------------------

---

- 10 -

Any determination or decision by or opinion of the Committee
made or held pursuant to the terms of the Plan shall be final, conclusive and
binding on all parties concerned. All rights, entitlements and obligations of
Participants under the Plan are set forth in the terms of the Plan and cannot be
modified by any other documents, statements or communications, except by Plan
amendments referred to in Section 7.1 of the Plan.

|8.5 | No Right to Employment
|--- | ----------------------

Participation in the Plan shall not be construed to give any
Participant a right to be retained as a Director.

|8.6 | No Other Benefit
|--- | ----------------

No amount will be paid to, or in respect of, a Participant
under the Plan to compensate for a downward fluctuation in the price of Common
Shares nor will any other form of benefit be conferred upon, or in respect of, a
Participant for such purpose.

|8.7 | No Shareholder Rights
|--- | ---------------------

Under no circumstances shall Deferred Share Units be considered
Common Shares nor shall they entitle any Participant to exercise voting rights
or any other rights attaching to the ownership of Common Shares nor shall any
Participant be considered the owner of Common Shares by virtue of the award of
Deferred Share Units.

|8.8 | Reorganization of the
Corporation
|--- | ---------------------------------

The existence of any Deferred Share Units shall not affect in
any way the right or power of the Corporation or its shareholders to make or
authorize any adjustment, recapitalization, reorganization or other change in
the Corporations capital structure or its business, or any amalgamation,
combination, merger or consolidation involving the Corporation or to create or
issue any bonds, debentures, shares or other securities of the Corporation or
the rights and conditions attaching thereto or to affect the dissolution or
liquidation of the Corporation or any sale or transfer of all or any part of its
assets or business, or any other corporate act or proceeding, whether of a
similar nature or otherwise.

|8.9 | Successors and Assigns
|--- | ----------------------

The Plan shall be binding on all successors and assigns of the
Corporation.

|8.10 | General Restrictions and
  Assignment
|---- | -------------------------------------

Except as required by law, the rights of a Participant under
the Plan are not capable of being anticipated, assigned, transferred, alienated,
sold, encumbered, pledged, mortgaged or charged and are not capable of being
subject to attachment or legal process for the payment of any debts or
obligations of the Participant.

|8.11 | Section 409A
|---- | ------------

It is intended that the provisions of this Plan comply with
Section 409A, and all provisions of this Plan shall be construed and interpreted
in a manner consistent with the requirements for avoiding taxes or penalties
under Section 409A. Notwithstanding anything in the Plan to the contrary, the
following will apply with respect to the rights and benefits of U.S. Eligible
Participants under the Plan:

| | (a) | Except as permitted under Section 409A, any deferred
      compensation (within the meaning of Section 409A) payable to or for the
      benefit of a U.S. Eligible Participant may not be reduced by, or offset
      against, any amount owing by the U.S. Eligible Participant to the
      Corporation or any of its affiliates.

| | (b) | If a U.S. Eligible Participant becomes entitled to
      receive payment in respect of any Deferred Share Units as a result of his
      or her separation from service (within the meaning of Section 409A), and
      the U.S Eligible Participant is a specified employee (within the meaning
      of Section 409A) at the time of his or her separation from service, and
      the Committee makes a good faith determination that (i) all or a portion
      of the Deferred Share Units constitute deferred compensation (within the
      meaning of Section 409A) and (ii) any such deferred compensation that
      would otherwise be payable during the six-month period following such
      separation from service is required to be delayed pursuant to the
      six-month delay rule set forth in Section 409A in order to avoid taxes or
      penalties under Section 409A, then payment of such deferred compensation
      shall not be made to the U.S Eligible Participant before the date which is
      six months after the date of his or her separation from service (and shall
      be paid in a single lump sum on the first day of the seventh month
      following the date of such separation from service) or, if earlier, the
      U.S Eligible Participants date of death.

|8.12 | Forfeiture Provision

If a Participant is subject to tax under the Income Tax Act(Canada) and also is a U.S. Eligible Participant with respect to DSUs, the
following special rules regarding forfeiture of such Deferred Share Units will
apply if the Participants DSUs are subject to Section 409A. For greater
clarity, these forfeiture provisions are intended to avoid adverse tax
consequences under Section 409A and/or under paragraph 6801(d) of the
regulations under the Income Tax Act(Canada), that may result because of
the different requirements as to the time of settlement of Deferred Share Units
with respect to a Participants separation from service (within the meaning of
Section 409A) (Separation From Service) and his retirement or loss of
office (under tax laws of Canada). If a Participant otherwise would be entitled
to payment of DSUs in any of the following circumstances, such DSUs shall
instead be immediately and irrevocably forfeited (for greater certainty, without
any compensation therefore):

| | (a) | a Participant experiences a Separation From Service as a
      result of a permanent decrease in the level of services provided to less
      than 20% of his past service in circumstances that do not constitute a
      retirement from, or loss of office or employment with, the Corporation or
      an affiliate thereof, within the meaning of paragraph 6801(d) of the
      regulations under the Income Tax Act(Canada); or

      thereof, within the meaning of paragraph 6801(d) of the regulations under
