EVIDENCE OF GRANT AND ACKNOWLEDGEMENT

CLASSIFICATION OF OPTIONS

VESTING OF TIME-BASED OPTIONS

Subject to Section 5(b) and Sections 6 to 11 hereof, Time-Based Options shall become Vested Options as follows:

30 percent on the first Anniversary Date;

an additional 30 percent on the second Anniversary Date; and

an additional 40 percent on the third Anniversary Date.

The number of Time-Based Options that become Vested Options under Section 5(a) shall be determined by rounding the result up to the nearest whole number of Time-Based Options, if necessary, to an aggregate maximum of the total number of Time-Based Options granted under this Agreement. No fractional Time-Based Options shall become Vested Options. No cash or other compensation shall be paid to the Participant at any time in lieu thereof any fractional Time-Based Options.

Subject to Sections 3 and 6 to 11, the Participant shall be entitled to exercise or surrender all or any number of the Vested Options, in accordance with Section 13, during the period from the Vesting Date of such Vested Option pursuant to Section 5(a) to the Expiry Date, or such earlier termination date as provided herein.

As an alternative to the exercise of a Vested Option, the Participant may surrender any Vested Option as to an associated TSAR in accordance with Section 13 hereof. Upon surrendering to the Corporation the Vested Options to purchase a specified number of Shares, the Participant shall receive a cash payment equal to the Appreciated Value multiplied by the number of Vested Options surrendered, less required applicable statutory and other withholdings. Thereafter the number of Vested Options so surrendered with respect to such specified number of Shares will be cancelled and terminated by the Corporation and the Participant shall have no further right, title or interest in such surrendered Vested Options or the underlying Shares.

TERMINATION OF EMPLOYMENT

Upon a Termination of Employment, the Participant shall be entitled to exercise or surrender any Vested Options during the Termination Exercise Period, but only to the extent such Vested Options have become Vested Options pursuant to Sections 5(a) or 11 on or prior to the Date Employment Ceases.

Notwithstanding Section 5(a), Time-Based Options which do not become Vested Options on or prior to the Date Employment Ceases shall not thereafter become Vested Options.

DEATH OR RETIREMENT OF PARTICIPANT

In the event the Participant ceases to be an employee of the Corporation or an Affiliated Entity by reason of the Participant’s death or Retirement on a date prior to the date he or she reaches age 60:

the Participant shall be entitled to exercise or surrender any Vested Options during the Death or Retirement Exercise Period, but only to the extent they have become Vested Options pursuant to Sections 5(a) or 11 on or prior to the date of such death or Date of Retirement, as applicable; and

notwithstanding Section 5(a), Time-Based Options which do not become Vested Options on or prior to the date of such death or Date of Retirement, as applicable, shall not thereafter become Vested Options.

In the event the Participant ceases to be an employee of the Corporation or an Affiliated Entity by reason of his or her death or Retirement on a date that occurs on or after the date he or she reaches the age 60, but before age 65, his or her Time-Based Options shall continue to become Vested Options in accordance with the provisions of this Agreement including, without limitation, Section 5(a), and the Participant shall be entitled to exercise or surrender any such Vested Options until the Expiry Date.

In the event the Participant ceases to be an employee of the Corporation or an Affiliated Entity by reason of his or her death or Retirement on a date that occurs on or after the date he or she reaches age 65, the Participant shall be entitled, during the period extending from the date of such death or Date of Retirement, as applicable, to the Expiry Date, to exercise or surrender, in full or in part, any unexercised Time-Based Option (irrespective of whether such Time-Based Option has become a Vested Option in accordance with the provisions of this Agreement including, without limitation Section 5(a)).

DISABILITY OF PARTICIPANT

LEAVES OF ABSENCE AND FAMILY LEAVE

In the event the Participant is on a Paid Leave of Absence or on Family Leave, Time-Based Options shall continue to be and become Vested Options in accordance with the provisions of this Agreement including, without limitation, Section 5(a), and the Participant shall be entitled to exercise or surrender any Vested Options during the period of such Paid Leave of Absence or Family Leave and thereafter, unless there occurs a Termination of Employment during such period, in which case the provisions of Section 6 shall apply, or unless the Participant’s death or Retirement occurs during such period, in which case the provisions of Section 7 shall apply.

In the event the Participant is on an Unpaid Leave of Absence:

Time-Based Options shall continue to be and become Vested Options in accordance with the provisions of Section 5(a) during the period commencing on the Date of Unpaid Leave of Absence and ending on the 31^st calendar day following the Date of Unpaid Leave of Absence, unless there occurs a Termination of Employment during such period, in which case the provisions of Section 6 shall apply, or unless the Participant’s death or Retirement occurs during such period, in which case the provisions of Section 7 shall apply;

notwithstanding Section 5(a), Time-Based Options which do not become Vested Options on or prior to the 31^st calendar day following the Date of Unpaid Leave of Absence shall not become Vested Options during the balance of the Participant’s Unpaid Leave of Absence, unless the Participant’s death or Retirement occurs during such period, in which case the provisions of Section 7 shall apply;

notwithstanding Section 5(a), Time-Based Options which do not become Vested Options on or prior to the 31^st calendar day following the Date of Unpaid Leave of Absence shall become Vested Options on the Participant’s Return to Service Date, but only to the extent that such Time-Based Options would have become Vested Options pursuant to Section 5(a) on or prior to the Return to Service Date if the period of Unpaid Leave of Absence had not occurred and provided that the Return to Service Date occurs prior to the Expiry Date;

in the event that the Participant’s Return to Service Date occurs prior to the Expiry Date, any Time-Based Options which did not become Vested Options on or prior to the 31^st calendar day following the Date of Unpaid Leave of Absence or pursuant to Section 9(b)(iii) shall become Vested Options solely in accordance with the provisions of Section 5(a); and

FORFEITURE AND TERMINATION OF TIME-BASED OPTIONS

Unless previously forfeited in accordance with the provisions hereof, upon the occurrence of a Termination of Employment, Time-Based Options which have not become Vested Options on or prior to the Date Employment Ceases shall be forfeited by the Participant and shall terminate on the Date Employment Ceases and, thereafter, the Participant will have no further right, title or interest in such Time-Based Options.

Upon the occurrence of a Termination of Employment, Vested Options which are not exercised or surrendered by the end of the Termination Exercise Period shall be forfeited by the Participant and shall terminate on the last day of the Termination Exercise Period and, thereafter, the Participant will have no further right, title or interest in such Vested Options.

Where the Participant ceases to be an employee of the Corporation or an Affiliated Entity by reason of the Participant’s death or Retirement on a date that is prior to the date that the Participant reaches age 60, unless previously forfeited in accordance with the provisions hereof, Time-Based Options which have not become Vested Options on or prior to the date of death or Date of Retirement, as applicable, shall be forfeited by the Participant and shall terminate on the date of death or Date of Retirement, as applicable, and, thereafter, the Participant will have no further right, title or interest in such Time-Based Options.

After the occurrence of any of the events in Sections 10(a) – (e), this Agreement shall terminate and be of no further force or effect whatsoever with respect to those Time-Based Options which have been forfeited and terminated or have expired and the Participant shall have no cause of action nor make any claim against the Corporation or any Affiliated Entity for damages or for loss of opportunity arising from the forfeiture and termination or expiry of such Time-Based Options or the termination of this Agreement insofar as it relates to such Time-Based Options pursuant to this Section 10.

EARLY EXERCISE AND ACCELERATED VESTING

Notwithstanding any other provision of this Agreement, but subject to Section 11(b), the Committee or the Board may pass a resolution which accelerates the vesting of a Time-Based Option and which permits the Participant to exercise or surrender in full or in part any unexercised Time-Based Option, whether or not the Time-Based Option has otherwise become a Vested Option, at such time or times and/or in such manner following the passing of such resolution as is specified in the resolution, which resolution may be passed for any reason which, in the sole opinion of the Committee or the Board, warrants altering the provisions pursuant to which a Time-Based Option vests or is exercisable or can be surrendered upon the occurrence of a Change in Control, including a Take-Over Bid which would, if successful, result in a Change in Control.

In the event of a Change in Control, all Time-Based Options granted to the Participant hereunder that are outstanding and are not Vested Options immediately prior to such Change in Control shall become Vested Options immediately prior to the occurrence of such Change in Control, and the Participant shall be entitled, commencing as of the time immediately prior to the occurrence of such Change in Control, to exercise in full or in part such Vested Options until the Expiry Date, and Section 11(b)(iii) shall apply, if applicable, except to the extent that an award of Options meeting the requirements set out below in this Section 11(b)(i) (such award, a “Replacement Award”) is provided to the Participant to replace such award of Time-Based Options (each award of Options intended to be replaced by a Replacement Award, a “Replaced Award”) effective on or immediately after the time of such Change in Control. An award of options shall meet the requirements of this Section 11(b)(i) (and hence qualify as a Replacement Award) if (A) it has an intrinsic value equal to the intrinsic value of the Replaced Award as of the

date of the Change in Control, (B) it relates to publicly traded equity securities of the Corporation, the entity surviving the Corporation following the Change in Control or the parent company of such surviving entity, (C) it contains terms relating to vesting that are substantially identical to those of the Replaced Award, and (D) its other terms and conditions are not less favorable to the Participant than the terms and conditions of the Replaced Award (including the provisions that would apply in the event of a subsequent Change in Control) as of the date of the Change in Control. Without limiting the generality of the foregoing, a Replacement Award may take the form of a continuation of the applicable Replaced Award if the requirements of the preceding sentence are satisfied. If a Replacement Award is granted, the Replaced Award shall not immediately vest prior to the occurrence of the Change in Control giving rise to the replacement. The determination whether the conditions of this Section 11(b)(i) are satisfied shall be made by the Committee, as constituted immediately before the Change in Control, in its sole discretion. All Time-Based Options that become Vested Options pursuant to this Section 11(b)(i) shall entitle the Participant, commencing as of the time immediately prior to the occurrence of the Change in Control, to exercise or surrender in full or in part such Vested Options until the Expiry Date.

Notwithstanding any other provision of this Agreement to the contrary, upon the Participant’s Termination of Employment by the Corporation or an Affiliated Entity, as applicable, without CIC Cause, or by the Participant for Good Reason, within the Specified Period following a Change in Control, the Participant shall be entitled, commencing as of the time immediately prior to such Termination of Employment, to exercise or surrender in full or in part any unexercised Time-Based Option (irrespective of whether such Time-Based Option has become a Vested Option in accordance with Section 5(a)) or Replacement Award, as applicable, until the Expiry Date.

If a “take-over bid” (within the meaning of applicable securities legislation) made by any person for the voting securities of the Corporation (a “Take-over Bid”) would, if successful, result in a Change in Control, and if a Replacement Award is not granted in accordance with Section 11(b)(i), then:

the Corporation will promptly notify the Participant of the Take-over Bid and the Participant’s rights under this Section 11(b)(iii);

vesting of all Time-Based Options that have not yet become Vested Options pursuant to Section 5(a) at the time a formal Take-over Bid offer has been made will be accelerated so as to be and become Vested Options (irrespective of whether such Time-Based Options have become Vested Options in accordance with Section 5(a)) on the date the formal Take-over Bid offer is made;

the Participant shall be entitled to exercise, in full or in part, the Time-Based Options in the manner set out in this Agreement, with any necessary modifications (or such other manner as may be prescribed by the Committee or the Board including, but not limited to, a form of cashless exercise), during the period ending on the earlier of the expiration of the Take-over Bid and the Expiry Date, for the purpose of tendering the Shares acquired pursuant to the exercise of the Time-Based Options to the Take-over Bid;

the Participant shall be entitled to deal with the Time-Based Options in such other manner (in addition to the exercise set out in paragraph 11(b)(iii)(C)) as may be prescribed by the Committee or the Board, in its discretion; and

if the Shares acquired pursuant to the exercise of the Time-Based Options are not deposited by the Participant pursuant to the Take-over Bid or, if deposited, are subsequently withdrawn by the Participant or not all taken up and paid for by the offeror or if the offeror fails to take-up and pay for the Shares pursuant to the terms of the Take-over Bid or if the Take-over Bid fails to close for any other reason, then the Participant shall promptly return such Shares (or the portion that are not taken up and paid for) to the Corporation for cancellation. Such Shares shall be deemed not to have been issued and the related Time-Based Options shall be deemed not to have been exercised, and the Corporation shall refund to the Participant, if applicable, the aggregate Exercise Price for the Time-Based Options. In such event, Time-Based Options will become Vested Options solely in accordance with Sections 5(a) or 11(b)(ii), and any other action by the Participant permitted in accordance with Section 11(b)(iii)(D) shall be deemed not to have occurred.
