5.2 More than one Option may be granted to the same Optionee, provided that such Optionee does not hold Options covering more than 5% of the issued and outstanding Total Shares.

The Estate shall be entitled to exercise the vested Options outstanding at the time of the Optionee’s death within the later of (i) 180 days of the Optionee’s death, or (ii) an extended period, if any, ending on the earlier of:

- the date on which the Estate Extension Period ends; or

Retirees shall be entitled to exercise the vested Options then outstanding, as the case may be within the later of (i) 90 days of the date of retirement or (ii) an extended period, if any, ending on the earlier of:

- the date on which the Extension Period ends; or

- the day that the Option Period expires; or

- the day on which the Optionee ceases to be retired pursuant to Section 1.18 of the Plan; and

If the date on which an Option expires occurs during a Blackout Period or within 10 Business Days after the last day of a Blackout Period, the date of expiry of such Option will be the last day of such 10 Business Day period.

8. Exercise of Option

8.1 A vested Option may be exercised in whole at any time or in part from time to time during the Option Period.

8.2 A vested Option may be exercised in such manner as the Corporate Secretary may determine from time to time, including, without limitation, processes administered by the Company or by third parties mandated by the Company, whether using telephone or Internet facilities, or otherwise. The process approved by the Corporate Secretary shall be posted on the human resources portion of the Company’s enterprise web portal and shall be communicated to Employees, Officers, Directors and Consultants by other means from time to time. Upon full payment of the subscription price together with any amount that may be required to be withheld or deducted under applicable taxation or other laws, the Company shall cause a certificate for the number of Shares indicated in the Optionee’s notice to be issued in the name of the Optionee and delivered to the address indicated in the notice no later than 10 business days following the exercise of the Option. If the Optionee does not remit to the Company such amount required to be withheld or deducted in cash at the time of the exercice, the Company may cause to be sold, in the market, such number of Shares underlying the Options as is necessary to pay such amount and shall use the proceeds of the sale for such purpose.

9. Subscription Price

The price at which Shares may be purchased under the Plan shall be determined by the Board based on the date an Option is granted, provided however that such price may not be less than the market price of the shares being the closing sale price of the Shares on the Toronto Stock Exchange on the trading day immediately preceding the date of grant.

10. Option Unassignable

The Optionee may not assign, pledge or encumber any Option nor any interest therein other than by will or under the law of succession.

11. Shareholder Rights

An Optionee shall not have any rights as a shareholder of the Company with respect to any of the Shares covered by his/her Option until the Optionee has become the registered holder of such Shares.

12. Effect of any Amendment to the Share Capital

In the event of any change in the number of outstanding Shares of the Company following any share dividend, subdivision, reorganization, merger, consolidation, combination or exchange of shares or any other similar corporate change, the Board shall make an equitable adjustment to the maximum number or the class of shares issuable under the Plan or covered by outstanding Options and to the subscription price for such shares. Such adjustment shall be final and binding for the purposes of the Plan.

13. Taxes imposed in respect of Options

Optionees shall be responsible for any tax that may be imposed either directly or indirectly on the Optionee or the Company or any of its subsidiaries in respect of the Optionee as a result of the grant of an Option or in respect of the benefit inuring to the Optionee in respect of any Option. The Company, or, as the case may be, the subsidiary of the Company that is liable to pay or withhold any such tax may, to the extent permitted by the law under which any such tax is imposed, recover from the Optionee in respect of whom the tax is imposed the amount of any such tax paid or payable.

14. Amendment and Termination

14.1 The Board, on the recommendation of the Committee, may, at any time and from time to time, amend, suspend or terminate the Plan, in whole or in part, or amend any term of any issued and outstanding Option (including, without limitation, the price at which Shares may be purchased under the Plan, the vesting and the expiry date of an outstanding Option) provided that no such amendment, suspension or termination may be made without:

14.1.1 Obtaining approval of the shareholders of the Company, unless not required pursuant to Section 14.2 or applicable regulatory authority or stock exchange requirements;

14.1.2 obtaining any required approval of any applicable regulatory authority or stock exchange; and

14.1.3 in the case of issued and outstanding Options, obtaining the consent or, subject to regulatory approval, the deemed consent of the concerned Optionee in the event that the amendment materially prejudices the Optionee’s rights.

14.2 Shareholder approval is not required with respect to the following amendments, in as much as the amendment is in accordance with applicable regulatory requirements:

- 6 -

14.2.1 changing the eligibility for, and limitations on, participation in the Plan;

14.2.2 modifying the periods referred to in Subsections 6.1.1 to 6.1.6 during which Options may be exercised, subject to, as the case may be, (i), subject to Section 7, the Option Period terminating on or before the tenth anniversary of the date of the grant of the Option, and (ii) a maximum Option exercise period extension of three years for any Employee, Officer, Consultant or Director;

14.2.3 changing the terms on which Options may be granted and exercised including, without limitation, the provisions relating to the price at which Shares may be purchased under the Plan, vesting, expiry, assignment and the adjustments to be made pursuant to Section 12;

14.2.4 making any addition to, deletion from or alteration of the provisions of the Plan that are necessary to comply with applicable law or the requirements of any applicable regulatory authority or stock exchange;

14.2.5 correcting or rectifying any ambiguity, defective provision, error or omission in the Plan; and

14.2.6 changing the provisions relating to the administration of the Plan;

unless any amendment made to the Plan would reduce the subscription price of an issued and outstanding Option, lead to a significant or unreasonable dilution of the outstanding Shares or provide additional material benefits to Insiders, in which case approval of the shareholders of the Company must be obtained. In addition, if an amendment would reduce the subscription price of any outstanding Option held by an Insider or would extend the expiry date of Options held by Insiders beyond the exercise periods contemplated under the Plan, approval of the shareholders of the Company, other than the relevant Insiders, must be obtained.
