PURPOSE AND ADMINISTRATION OF THE PLAN

The purpose of this Plan is to strengthen the alignment of interests between the Eligible Directors and the shareholders of the Corporation, including the Issuer and its shareholders, by linking a portion of annual director compensation to the future value of the Common Shares. In addition, this Plan has been adopted for the purpose of advancing the interests of the Corporation and the Issuer through the motivation, attraction and retention of directors of the Corporation and the Designated Affiliates of the Corporation. It is generally recognized that deferred stock unit plans aid in attracting, retaining and encouraging director commitment and performance due to the opportunity offered to them to receive compensation in line with the value of an entity’s equity.

This Plan shall be administered by the Board and the Board shall have full authority to administer this Plan including the authority to interpret and construe any provision of this Plan and to adopt, amend and rescind such rules and regulations for administering this Plan as the Board may deem necessary in order to comply with the requirements of this Plan. All actions taken and all interpretations and determinations made by the Board in good faith shall be final and conclusive and shall be binding on the Participants and the Corporation. No member of the Board shall be personally liable for any action taken or determination or interpretation made in good faith in connection with this Plan and all members of the Board shall, in addition to their rights as directors of the Corporation, be fully protected, indemnified and held harmless by the Corporation with respect to any such action taken or determination or interpretation made in good faith. The appropriate officers of the Corporation are hereby authorized and empowered to do all things and execute and deliver all instruments, undertakings and applications and writings as they, in their absolute discretion, consider necessary for the implementation of this Plan and of the rules and regulations established for administering this Plan. All costs incurred in connection with this Plan shall be for the account of the Corporation.

The Corporation shall maintain a register in which shall be recorded:

DEFERRED PHANTOM STOCK UNIT AWARDS

This Plan is hereby established for Eligible Directors.

The Board shall grant and issue to each Eligible Director on each DSU Issue Date, that number of Deferred Phantom Stock Units having a value equal to 50% of the Director’s Remuneration payable to such Eligible Director for the current Quarter (the “Entitlement”). More specifically, the number of Deferred Phantom Stock Units to be granted to an Eligible Director will be determined by dividing the Entitlement by the closing price for a Common Share on the TSX on the business day immediately preceding the DSU Issue Date.

Within 30 days of the Separation Date, a Participant may deliver to the Corporation a Redemption Notice specifying a Redemption Date.

Each Deferred Phantom Stock Unit held by a Participant who ceases to be an Eligible Director shall be redeemed by the Corporation on the relevant Redemption Date for a DSU Payment to be made to the Participant on the Participant’s Redemption Date without any further action on the part of the holder of the Deferred Phantom Stock Unit in accordance with this Article Three.

Each grant of Deferred Phantom Stock Units under this Plan shall be evidenced by a letter issued to the Participant by the Corporation (“DSU Grant Letter”). Such Deferred Phantom Stock Units shall be subject to all applicable terms and conditions of this Plan and may be subject to any other terms and conditions which are not inconsistent with this Plan and which the Board deems appropriate for inclusion in a DSU Grant Letter. The provisions of the various DSU Grant Letters entered into under this Plan need not be identical, and may vary from Quarter to Quarter and from Participant to Participant.

In the event that a dividend (other than stock dividend) is declared and paid by the Issuer on Common Shares, a Participant will be credited with additional Deferred Phantom Stock Units. The number of such additional Deferred Phantom Stock Units will be calculated by dividing the total amount of the dividends that would have been paid to the Participant if the Deferred Phantom Stock Units in the Participant’s account

on the dividend record date had been outstanding Common Shares (and the Participant held no other Common Shares), by the Market Value as determined on the date on which the dividends were paid on the Common Shares.

This Plan, as set forth herein, shall be deemed to become effective as of January 1, 2011. This Plan shall remain in effect until it is terminated by the Board. Upon termination of this Plan, the Corporation shall redeem all remaining Deferred Phantom Stock Units under Section 3.3 above, as at the applicable Separation Date for each of the remaining Participants.

ARTICLE 4

WITHHOLDING TAXES

The Corporation or any Designated Affiliate of the Corporation will withhold any taxes or source deductions which the Corporation or any Designated Affiliate of the Corporation is required by any law or regulation of any governmental authority whatsoever to withhold in connection with any payment made under this Plan.

ARTICLE 5

GENERAL

The Board may from time to time in the absolute discretion of the Board amend, modify and change the provisions of this Plan, provided that any amendment, modification or change to the provisions of this Plan which would:

shall only be effective upon such amendment, modification or change being approved by the Board, and, if required, by the TSX and any other regulatory authorities having jurisdiction over the Corporation and provided any such amendment shall be effective only if this Plan will continue to meet the requirements of paragraph 6801(d) of the regulations to the Income Tax Act (Canada) or any successor to such provision.

The Board may amend or discontinue this Plan at any time in its sole discretion, provided that such amendment or discontinuance may not in any manner adversely

- 7 -

affect the Participant’s rights under any Deferred Phantom Stock Unit granted under this Plan

Except as otherwise may be expressly provided for under this Plan or pursuant to a will or by the laws of intestacy, no Deferred Stock Unit and no other right or interest of a Participant is assignable or transferable, and any such assignment or transfer in violation of this Plan shall be null and void.

No holder of any Deferred Phantom Stock Units shall have any rights as a shareholder of the Corporation or the Issuer at any time. Nothing in this Plan shall confer on any Eligible Director the right to continue as a Director of the Corporation or as a director of any Designated Affiliate or interfere with right to remove such director.

In the event there is any change in the Common Shares, whether by reason of a stock dividend, stock split, reverse stock split, consolidation, subdivision, reclassification or otherwise, an appropriate proportionate adjustment shall be made by the Board with respect to the number of Deferred Phantom Stock Units then outstanding under this Plan as the Board, in its sole discretion, may determine to prevent dilution or enlargement of rights.

All such adjustments, as determined by the Board, shall be conclusive, final and binding for all purposes of this Plan.

The Corporation makes no representation or warranty as to the future value of any rights of Deferred Phantom Stock Units issued in accordance with the provisions of this Plan. No amount will be paid to, or in respect of, an Eligible Director under this Plan or pursuant to any other arrangement, and no additional Deferred Phantom Stock Units will be granted to such Eligible Director to compensate for a downward fluctuation in the price of the Common Shares, nor will any other form of benefit be conferred upon, or in respect of, an Eligible Director for such purpose.

If any provision of this Plan or any Deferred Phantom Stock Unit contravenes any law or any order, policy, by-law or regulation of any regulatory body having jurisdiction, then such provision shall be deemed to be amended to the extent necessary to bring such provision into compliance therewith.

This Plan shall be governed by and construed in accordance with the laws of the Province of British Columbia.
