Section 2 Election Under the Plan

Subject to Section 2.2 and such rules, regulations, approvals and conditions as the Committee may impose, an Eligible Director will receive 50% of his or her Annual Retainer in the form of Deferred Stock Units and may elect to receive any or all of the remainder of his Annual Retainer (“Elective Annual Retainer”) in the form of Deferred Stock Units. Any portion of the Eligible Director’s Elective Annual Retainer that is not so-elected will be paid in cash in Quarterly installments. Further, as part of the election with regard to the form or forms of payment of his or her Elective Annual Retainer, an Eligible Director may elect to have the portion of his or her Annual Retainer being paid in the form of Deferred Stock Units redeemed in return for Common Stock (i) immediately at the end of each Quarter or (ii) six months after his or her Termination Date (in either case, the “Entitlement Date.”)

(a) A person who is an Eligible Director on the effective date of the Plan may elect a form or forms of payment of his or her Elective Annual Retainer payable for services provided after such effective date of the Plan by completing and delivering to the Secretary of the Company an initial Election Notice by no later than 30 days after the effective date of the Plan, which shall apply to the Eligible Director’s Elective Annual Retainer payable for services provided after the effective date of such election, subject to the provisions of Section 2.2(c).

4

(b) An individual who becomes an Eligible Director during a year may elect the form or forms of payment of his or her Elective Annual Retainer earned in Quarters that commence after the date the election is made by completing and delivering to the Secretary of the Company an Election Notice. Such Election Notice shall not be effective if (i) such Election Notice is not completed and delivered to the Secretary of the Company within 30 days after the individual becomes an Eligible Director; or (ii) the individual previously participated in this Plan or any other plan that is required to be aggregated with this Plan for purposes of Section 409A of the Code.

(c) An Eligible Director who has made an election under Section 2.2(a) or 2.2(b), or who has never made any such election, may elect the form or forms of payment of his or her Elective Annual Retainer for a subsequent fiscal year by completing and delivering to the Secretary of the Company a new Election Notice on or before December 31 immediately preceding the first day of such subsequent fiscal year.

(d) For greater certainty, if the Company establishes a policy for members of the Board with respect to the acquisition and/or holding of Common Stock and/or DSUs, each Director shall ensure that any election he or she makes under this Section 2.2 complies with such policy.

2.3.1 Deferred Stock Units shall be credited to the Eligible Director’s Account as of the applicable Credit Date. The number of Deferred Stock Units (including fractional Deferred Stock Units) to be credited to an Eligible Director’s Account as of a particular Credit Date pursuant to this Section 2.3.1 shall be determined by dividing the portion of that Eligible Director’s Annual Retainer for the applicable period to be satisfied by Deferred Stock Units by the Fair Market Value on the particular Credit Date.

2.3.2 Deferred Stock Units credited to an Eligible Director’s Account under Section 2.3.1, together with any additional Deferred Stock Units granted in respect thereof under Section 2.4, will be fully vested upon being credited to an Eligible Director’s Account and the Eligible Director’s entitlement to payment of such Deferred Stock Units at his or her Entitlement Date shall not thereafter be subject to satisfaction of any requirements as to any minimum period of membership on the Board.

On any payment date for dividends paid on Common Stock, an Eligible Director shall be credited with dividend equivalents in respect of Deferred Stock Units credited to the Eligible Director’s Account as of the record date for payment of dividends. Such dividend equivalents shall be converted into additional Deferred Stock Units (including fractional Deferred Stock Units) based on the Fair Market Value as of the date on which the dividends on the Common Stock are paid.

5

An Eligible Director’s Account shall record at all times the number of Deferred Stock Units standing to the credit of the Eligible Director. Upon payment or delivery of Common Stock in satisfaction of Deferred Stock Units credited to an Eligible Director in the manner described herein, such Deferred Stock Units shall be cancelled. A written confirmation of the balance in each Eligible Director’s Account shall be provided by the Company to the Eligible Director at least annually.

Notwithstanding any other provision of the Plan, in the event of any change in the Common Stock by reason of any stock dividend, split, recapitalization, reclassification, amalgamation, arrangement, merger, consolidation, combination or exchange of Common Stock or distribution of rights to holders of Common Stock or any other form of corporate reorganization whatsoever, an equitable adjustment shall be made to any Deferred Stock Units then outstanding. Such adjustment shall be made by the Committee, subject to Applicable Law, shall be conclusive and binding for all purposes of the Plan.

Upon the occurrence of a Covered Transaction, as that term is defined in Section 9(f) of the EIP, the following shall apply:

(a) Unless otherwise determined by the Board, such fractional portion of an Eligible Director’s Annual Retainer earned in the current Quarter but not yet paid shall be immediately paid in accordance with Section 2.1, and the Credit Date shall be immediately prior to the effective date of the Covered Transaction.

(b) The Committee, in its discretion, may take one or more of the following actions:

(1) Provide for the acceleration of any time period relating to the redemption of the Deferred Stock Units (provided that acceleration is only permitted to the extent permitted by Section 409A of the Code, as applicable);

(2) Provide for the cancellation of the Deferred Stock Units (without the consent of the Eligible Director) in exchange for the payment to the Eligible Director of cash or other property with a Fair Market Value equal to the amount that would have been received (net of any taxes required to be withheld) upon the redemption of the Deferred Stock Units had the Deferred Stock Units been redeemed immediately prior to the Covered Transaction;

(3) Adjust the terms of the Deferred Stock Units in a manner determined by the Committee to reflect the Covered Transaction;

(4) Cause the Deferred Stock Units or the Plan to be assumed, or new rights substituted therefore, by any other entity; or

6

(5) Make such other provision as the Committee may consider equitable to the Eligible Directors and in the best interests of the Company.

Section 3 Redemptions

Subject to Section 3.3, all vested Deferred Stock Units credited to an Eligible Director’s Account on his or her Entitlement Date shall be redeemed in return for Common Stock on such date.

In the event that the Committee is unable, by an Eligible Director’s Entitlement Date, to compute the final value of the Deferred Stock Units recorded in such Eligible Director’s Account by reason of the fact that any data required in order to compute the market value of a Stock has not been made available to the Committee and such delay is not caused by the Eligible Director, then the Entitlement Date shall be the next following trading day on which such data is made available to the Committee.

Notwithstanding any other provision of the Plan, all amounts payable to, or in respect of, an Eligible Director hereunder shall be paid on or before December 31 of the calendar year commencing immediately after the Eligible Director’s Entitlement Date.

Section 4 General

Unless otherwise determined by the Committee, the Plan shall be unfunded. To the extent any individual holds any rights by virtue of an election under the Plan, such rights (unless otherwise determined by the Committee) shall be no greater than the rights of an unsecured general creditor of the Company.

The Plan shall be binding on all successors and permitted assigns of the Company and an Eligible Director, including without limitation, the estate of such Eligible Director and the legal representative of such estate, or any receiver or trustee in bankruptcy or representative of the Company’s or the Eligible Director’s creditors.

7

The Board may amend or terminate the Plan at any time it deems necessary or appropriate, but no such amendment or termination shall, without the consent of the Eligible Director or unless required by law, adversely affect the rights of an Eligible Director with respect to any amount of his or her Annual Retainer in respect of which an Eligible Director has then received or elected to receive Deferred Stock Units. Notwithstanding the foregoing, any amendment or termination of the Plan shall be such that the Plan continuously meets the requirements of Section 409A of the Code.

For avoidance of doubt, if any provision of the Plan contravenes any regulations or U.S. Treasury guidance promulgated under Section 409A of the Code or would cause the Deferred Stock Units to be subject to the interest and penalties under Section 409A of the Code, such provision of the Plan shall be modified, without the consent of any Eligible Director, to maintain, to the maximum extent practicable, the original intent of the applicable provision without violating the provisions of Section 409A of the Code.

The Committee and each Eligible Director will ensure that all actions taken and decisions made by the Committee or an Eligible Director, as the case may be, pursuant to the Plan, comply with applicable securities regulations and policies of the Company relating to insider trading and “black out” periods. All Deferred Stock Units shall be considered a “security” of the Company solely for reporting purposes under the insider trading policy and pre-clearance procedures of the Company.

Subject to the requirements of Applicable Law, an Eligible Director may designate in writing a person who is a dependant or relation of the Eligible Director as a beneficiary to receive any benefits that are payable under the Plan upon the death of such Eligible Director. The Eligible Director may, subject to Applicable Law, change such designation from time to time. Such designation or change shall be in the form of Schedule B. The initial designation of each Eligible Director shall be executed and filed with the Secretary of the Company within sixty (60) days following the Effective Date of the Plan. Changes to such designation may be filed from time to time thereafter.

In the event of an Eligible Director’s death, any and all Deferred Stock Units then credited to the Eligible Director’s Account shall become payable to the Eligible Director’s Beneficiary in accordance with Section 3 and the date of death shall be deemed to be the Termination Date.

8

4.8.1 Except as specifically set out in the Plan, no Eligible Director or any other person shall have any claim or right to any benefit in respect of Deferred Stock Units granted or Annual Retainers payable pursuant to the Plan.

4.8.2 Rights of Eligible Directors respecting Deferred Stock Units and other benefits under the Plan shall not be transferable or assignable other than by will or the laws of descent and distribution.

4.8.3 The Plan shall not be construed as granting an Eligible Director a right to be retained as a member of the Board or a claim or right to any future grants of Deferred Stock Units, future Annual Retainers or other benefits under the Plan.

4.8.4 Under no circumstances shall Deferred Stock Units be considered Common Stock nor shall they entitle any Eligible Director or other person to exercise voting rights or any other rights attaching to the ownership of Common Stock.

Any obligation of the Company pursuant to the terms of the Plan is subject to compliance with Applicable Law. The Eligible Directors shall comply with Applicable Law and furnish the Company with any and all information and undertakings as may be required to ensure compliance therewith.

For greater certainty, and without derogation from any rights the Company may have with respect to the withholding of taxes, source deductions or other amounts pursuant to Applicable Law, the Company shall be entitled to deduct any amount of withholding taxes and other withholdings from any amount paid or credited hereunder for purposes of compliance or intended compliance with Applicable Law.
