The Plan became effective as of January 1, 2005 for amounts deferred in respect of fiscal 2005 and subsequent performance periods. The restatement of the Plan became effective as of January 1, 2008.

No adjustment or amendment under this paragraph 9 shall affect the timing of any redemptions under the Plan or the timing or form of any payments under the Plan.

10. Redemption of Units. Subject to the provisions of paragraph 5A and the terms of any grants made thereunder, Deferred Stock Units will be redeemable and the value thereof payable in accordance with the applicable provisions of this paragraph 10 after the Participant has a Termination of Employment or dies.

(a) Termination of Employment.

(i) Subject to subparagraph 10(a)(ii), if a Participant has a Termination of Employment, the aggregate value of the Participant’s Deferred Stock Units will be redeemed automatically on the earlier of (i) thirty (30) days after the date of such Participant’s Termination of Employment and (ii) December 31st of the calendar year that includes the date of such Termination of Employment or, if later, the 15th day of the first calendar month that begins after the date of such Termination of Employment.

- 5 -

(ii) Notwithstanding anything to the contrary in subparagraphs (a)(i) and (c) hereof, if a Participant who is a Specified Employee has a Termination of Employment, no redemption of Deferred Stock Units nor payment in respect thereof shall be made under this Plan to such Participant prior to the date that is six months after the date of such Participant’s Termination of Employment, unless it is determined that payment would constitute a short-term deferral within the meaning of United States Treasury Regulation Section 1.409A-1(b)(4).

(b) Death. If the Participant dies before having a Termination of Employment, the aggregate value of the Participant’s Deferred Stock Units will be redeemed no later than the 60th day after the date of the Participant’s death and paid to the beneficiary of the Deferred Stock Units appointed in the Participant’s will or, in the absence of such beneficiary, the legal representative of the Participant’s estate. Any unvested Deferred Stock Units will automatically vest upon the Participant’s death.

(c) Payment Forms.

(i) The aggregate value of the Deferred Stock Units redeemed under this paragraph 10 and determined in accordance with paragraph 7 as at the redemption date will be paid net of any applicable withholdings to the Participant, or in the event of the Participant’s death, his beneficiary or legal representative, in a single-sum cash payment. The Administrator shall establish procedures for the Participant or beneficiary or legal representative to make such elections and; in the event that no such election is made in accordance with such procedures, payment shall be made in cash. If the Participant elects for the cash payment to be used to purchase Common Shares, the Bank shall contribute to an account of a custodian or other independent agent (the “Custodian”) an amount of cash sufficient to purchase the whole number of Common Shares to which the Participant is entitled and, upon making such contribution, payment shall be deemed to have been made. The Custodian shall, as soon as practicable thereafter, purchase those Common Shares on a securities exchange on which the Common Shares are listed or traded. Any fractional shares shall be paid in cash based on the Value of a Unit on the redemption date. The Custodian shall deliver to the Participant a certificate for the Common Shares purchased or deposit such Common Shares into a stock brokerage account maintained by the Participant.

(ii) Subject to subparagraph 10 (a)(ii), all amounts payable to a Participant who has had a Termination of Employment shall be paid on the earlier of (i) thirty (30) days after the date of such Participant’s Termination of Employment and (ii) December 31st of the calendar year that includes the date of such Termination of Employment or, if later, the 15th day of the first calendar month that begins after the date of such Termination of Employment. All amounts payable to a beneficiary of a Participant who has died shall be paid no later than the last day of the Participant’s taxable

- 6 -

year that includes the date of such death or, if later, the 15th day of the third calendar month that begins after the date of such death.

(iii) In all cases where the Participant elects that the cash payment be used to purchase Common Shares, the redemption may take effect only within such periods as are designated from time to time by the Bank’s Compliance Department as being “trading windows” open for trading by Bank executives. In the event that the redemption date does not fall during a “trading window” period, payment will be made in cash.

(d) Compliance with Canadian Tax Rules. If redemption and payment otherwise would be required to be made pursuant to this paragraph 10 at a time when payment is not permitted to be made in accordance with the Canadian Tax Rules to the extent the Canadian Tax Rules are applicable, then, notwithstanding any other provision of this paragraph 10, such payment shall be made to a trustee to be held in trust for the benefit of the Participant in a manner that causes the payment to be included in the Participant’s income under the Code and does not violate the Canadian Tax Rules, provided that if the Administrator determines that payment may be made to the Participant in some other manner and/or time which complies simultaneously with the requirements of Section 409A and the Canadian Tax Rules, then the Administrator may direct that such payment be paid in such manner and/or at such time.

(e) Prohibition on Becoming an Independent Contractor. Following a cessation of employment with the Bank and all Bank Affiliates, a Participant who is subject to the Canadian Tax Rules is prohibited from providing services to the Bank and any Bank Affiliate as an independent contractor for a period that does not end before the end of the calendar year that begins after such cessation of employment.

11. Transferability of Awards. Deferred Stock Units shall not be subject to anticipation, alienation, sale, pledge, encumbrance, attachment, or garnishment and shall not be transferable or assignable other than by will or the laws of succession.

12. No Right to Employment. Neither participation in the Plan nor any action under the Plan shall be construed to give any Participant a right to be retained in the employment of the Bank or of any Bank Affiliate.

13. Unfunded Plan. Unless otherwise determined by the Committee, the Plan shall be unfunded and any obligation to make a payment in the future upon redemption of Deferred Stock Units will remain an unfunded liability recorded on the books of the Bank. To the extent any person holds any rights by virtue of a grant awarded under the Plan, such rights (unless otherwise determined by the Committee) shall be no greater than the rights of an unsecured creditor of the Bank.

14. Successors and Assigns. The Plan shall be binding on all successors and assigns of the Bank and a Participant, including without limitation, the estate of such

- 7 -

Participant and the executor, administrator or trustee of such estate, or a receiver or trustee in bankruptcy or representative of the Participant’s creditors.

15. Administration. The Plan shall be administered by the Administrator on behalf of and under instructions of the Committee.

The Committee shall, in its absolute discretion: (i) interpret the Plan; (ii) establish, amend and rescind any rules and regulations relating to the Plan; (iii) make any other determinations that the Committee deems necessary or desirable for the administration of the Plan, (iv) and correct any defect or supply any omission or reconcile any inconsistency in the Plan in the manner and to the extent the Committee deems necessary or desirable. Any decision of the Committee in the interpretation and administration of the Plan, as described herein, shall be final, conclusive and binding on all parties concerned. The Committee shall have the power to delegate, on such terms as the Committee deems appropriate, any or all of its powers and responsibilities under this Plan to the Chief Executive Officer of the Bank, including the power to make discretionary decisions.

16. Plan Amendment.

(a) The Administrator may amend the Plan and the form of any notice or election relating to Deferred Stock Units:

(i) as may be required to conform to applicable laws (and interpretations thereof published by the relevant governmental authority, including applicable tax laws and Code section 409A;

(ii) as may be required or desired for the efficient administration of the Plan; provided that no amendment shall be inconsistent with the intentions underlying the Plan as described in subparagraph 1(a) nor shall it affect the substance of the Plan and the Deferred Share Units; and further provided that if authority over a proposed amendment is specifically delegated to the Committee in its charter, the Committee shall have such authority in place of the Administrator.

(b) The Committee may amend the Plan and the terms of any notice or election relating to Deferred Stock Units (including Additional Deferred Stock Units) as it deems necessary or appropriate, provided that no amendment shall be inconsistent with the intentions underlying the Plan as described in subparagraph 1 (a).

(c) Notwithstanding subparagraphs 16(a) and (b), except to the extent required to conform the Plan to applicable laws (including applicable tax laws), no such amendment shall, without the consent of the affected Participant adversely affect the rights of the Participant with respect to Deferred Stock Units to which the Participant is entitled at the time of amendment under the Plan.

17. Plan Termination. The Committee may terminate the Plan at any time. However, if so terminated, prior awards shall remain outstanding and in effect in accordance with their applicable terms and conditions.

- 8 -

18. Value of Deferred Stock Units Not Guaranteed. The value of a Deferred Stock Unit is based on the price of a Common Share and is thus not guaranteed. The value of a Deferred Stock Unit at the time it is redeemed may be higher or lower than the value at the time any election is made or any Deferred Stock Unit is credited to a Participant’s account under the Plan. 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.

19. Tax Matters and Withholding. Regardless of any action that the Bank or any applicable Bank Affiliate takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding related to the Deferred Stock Units and legally applicable to the Participant (“Tax-Related Items”), the Participant acknowledges that the ultimate liability for all Tax-Related Items legally due by the Participant is and remains Participant’s responsibility and may exceed the amount actually withheld by the Bank or the Bank Affiliate. The Participant further acknowledge that the Bank and/or the Bank Affiliate (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the awards, including the grant, vesting or redemption of the awards; and (b) do not commit to structure the terms of the awards or any aspect of the awards to reduce or eliminate Participant’s liability for Tax-Related Items or to achieve any particular tax result. Prior to any relevant taxable or tax withholding event, as applicable, the Participant will pay or make adequate arrangements satisfactory to the Bank and/or the Bank Affiliate to satisfy all Tax-Related Items. In this regard, Participant authorizes the Bank and/or the Bank Affiliate to withhold all applicable Tax-Related Items legally payable by Participant from wages or other cash compensation paid to Participant by Bank and/or the Bank Affiliate. The Bank or Custodian may refuse to deliver the Common Shares or any amount payable to the Participant if there is a failure to comply with the obligations in connection with Tax-Related Items.

20. Governing Law/Severability. The validity, construction and effect of the Plan and any actions taken or relating to the Plan shall be governed by the substantive laws, but not the choice of law rules, of the Province of Ontario. In the event any provision of this Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included. This Plan constitutes the final understanding between the Participant and the Bank regarding these awards. Any prior agreements, commitments or negotiations concerning these Awards are superseded.

21. Claim Procedure For Benefits

(a) The Committee will endeavor to administer the Plan fairly and consistently and to pay all benefits to which Participants or beneficiaries are properly entitled. All claims for unpaid benefits should be made in writing to the Committee. The Committee may request additional information necessary to consider the claim further. If a claim is wholly or partially denied, the Committee will notify the claimant of the adverse decision within a reasonable period of time, but not later than ninety (90) days after receiving the claim, unless the Committee determines

- 9 -

that special circumstances require an extension. In such case, a written extension notice shall be furnished before the end of the initial 90-day period. The extension cannot exceed ninety (90) days. The extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Committee expects to render the decision. The claim determination time frames begin when a claim is filed, without regard to whether all the information necessary to make a claim determination accompanies the filing. Any notice of denial shall include:

(i) The specific reason or reasons for denial with reference to those specific Plan provisions on which the denial is based;

(ii) A description of any additional material or information necessary to perfect the claim and an explanation of why that material or information is necessary; and

(iii) A description of the Plan’s appeal procedures and time frames, including a statement of the claimant’s right to bring a civil action following an adverse decision on appeal.

(b) A claimant, or a claimant’s authorized representative, may appeal a denied claim within sixty (60) days after receiving the Committee’s notice of denial. A claimant has the right to:

(i) Submit to the Committee, for review, written comments, documents, records and other information relating to the claim;

(ii) Request, free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claimant’s claim; and

(iii) A review on appeal that takes into account all comments, documents, records, and other information submitted by the claimant, without regard to whether such information was submitted or considered in the initial claim decision.

The Committee will make a full and fair review of the appeal and may require additional documents as it deems necessary in making such a review. A final decision on review shall be made within a reasonable period of time, but not later than sixty (60) days following receipt of the written request for review, unless the Committee determines that special circumstances require an extension. In such case, a written extension notice will be sent to the claimant before the end of the initial 60-day period. The extension notice shall indicate the special circumstances and the date by which the Committee expects to render the appeal decision. The extension cannot exceed a period of sixty (60) days. The appeal time frames begin when an appeal is filed, without regard to whether all the information necessary to make an appeal decision accompanies the filing. If an extension is necessary because the claimant failed to submit necessary information, the days from the date the Committee sends the extension notice until the claimant responds to the request for additional information are not counted as part of the appeal determination period. The Committee’s notice of

- 10 -

denial on appeal shall include:

(i) The specific reason or reasons for denial with reference to those Plan provisions on which the denial is based;

(ii) A statement that the claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of all documents, records, and other information relevant to the claimant’s claim; and

(iii) A statement describing any voluntary appeal procedures offered by the Plan and the claimant’s right to obtain the information about such procedures, and a statement of the claimant’s right to bring an action under the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).

22. Electronic Delivery. By participating in the Plan or accepting the Deferred Stock Units granted under it, each Participant consents and agrees (i) to electronic delivery of any documents that the Bank may elect to deliver (including, but not limited to, plan documents, grant or award notifications, notices, deferral elections and agreements, and all other forms of communications) in connection with any Award made or offered under the Plan; (ii) that any and all procedures the Bank has established or may establish for an electronic signature system for delivery and acceptance of any such documents that the Bank may elect to deliver, and agrees that his or her electronic signature is the same as, and shall have the same force and effect as, his or her manual signature; and (iii) that any such procedures and delivery may be affected by a third party engaged by the Bank to provide administrative services related to the Plan.

23. Acknowledgements. By accepting the grant of the Deferred Stock Units, the Participant acknowledges and agrees that:

(a) the Deferred Stock Units are granted voluntarily by the Bank, are discretionary in nature, and may be modified, suspended, or terminated by the Bank at any time;

(b) the Deferred Stock Units are voluntary and occasional and do not create any contractual or other right to receive future awards of cash or benefits in lieu of cash, even if awards have been awarded repeatedly in the past;

(c) all decisions with respect to future Deferred Stock Units, if any, will be at the sole discretion of the Bank;

(d) the Deferred Stock Units are an extraordinary item that do not constitute compensation of any kind for services of any kind rendered to the Bank or the Employer, and which are outside the scope of the Participant’s employment contract, if any;

(e) the Deferred Stock Units are not part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement benefits or welfare benefits or

- 11 -

similar payments, and in no event should be considered as compensation for, or in any way relating to, past services for the Bank or any Bank Affiliate;

(f) in consideration of the grant of the Deferred Stock Units, no claim or entitlement to compensation or damages arises from forfeiture of the Deferred Stock Units resulting from Participant’s termination for cause and Participant’s irrevocably releases the Bank and the Employer from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, then, by accepting this award, Participant shall be deemed irrevocably to have waived his or her entitlement to pursue such claim;

(g) the Participant is solely responsible to investigate and comply with any exchange control laws applicable to the Participant in connection with the grant and redemption and any payments pursuant to the Deferred Stock Units; and

(h) the Bank is not providing any tax, legal, or financial advice, nor is the Bank making any recommendations regarding the Deferred Stock Units. The Participant is hereby advised to consult with his or her personal tax, legal, and financial advisors regarding the awards before taking any action in relation thereto.

23. Country Specific Provisions.

(a) Notwithstanding any provisions in this Plan, the Deferred Stock Units shall be subject to any special terms and conditions set forth in Exhibit A to this Plan for the applicable country. Moreover, if the Participant relocates to one of the countries included in Exhibit A, the special terms and conditions for such country will apply to the Participant to the extent that the Bank determines that the application of such terms and conditions is necessary or advisable in order to comply with local law or facilitate the administration of the awards. Exhibit A constitutes part of this Plan.

(b) If the Participant moves to any other country, additional terms and conditions may apply to the Participant’s awards. The Bank reserves the right to impose other requirements on the awards to the extent the Bank determines it is necessary or advisable in order to comply with local law or facilitate the administration of the awards and to require the Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing.

The Bank shall not be required to deliver any redemption payment or proceeds until such obligations are satisfied.

The following sections supplement the provision regarding tax and social insurance contribution withholding/reporting authorizations/responsibility in the Plan:

Any sum withheld on an estimated basis will be repaid to the Participant to the extent that such sum was not applied in satisfaction of the actual tax liabilities arising.

At the Bank’s direction, Participant shall satisfy any tax and National Insurance Contribution withholding obligation by one or some combination of the following methods: (a) by cash payment, (b) from salary, or (c) from any cash payment payable to the Participant upon redemption of the Deferred Stock Units.

If payment or withholding of the Tax-Related Items is not made within 90 days of the event giving rise to the Tax-Related Items (the “Due Date”) or such other period specified in Section 222(1)(c) of the United Kingdom Income Tax (Earnings and Pensions) Act 2003, the amount of any uncollected Tax-Related Items will constitute a loan owed by the Participant to the Employer, effective on the Due Date. The Participant agrees that the loan will bear interest at the then-current Official Rate of Her Majesty’s Revenue and Customs (“HMRC”), that it will be immediately due and repayable, and that the Bank, Custodian or the Employer may recover it at any time thereafter by any of the means referred to in the Plan. The Participant will be responsible for reporting and paying any income tax and National Insurance Contributions due on this additional benefit directly to HMRC under the self-assessment regime.
