4.4 The Option Price on Shares which are the subject of any Options shall in no circumstances be lower than the Market Price of the Shares on the date of the grant of the Option.

4.5 In no event may the term of an Option exceed ten years from the time of the grant of the Option.

4.7 An Option is personal to the Optionee and is non-assignable.

4.8 If, at any particular time, an Option is exercisable as to only part of the Shares to which the Option relates, and if a Public Take-over Bid is made, the Board, in its sole discretion, may determine that the Optionee may forthwith and thereafter until the expiry of the Option in accordance with its terms exercise the Option with respect to all of the Shares to which the Option relates which have not been taken up by the Optionee prior to the date of such determination.

ARTICLE 5

Termination of Employment, Death, Retirement and Resignation

5.1 An Option, and all rights to purchase Shares pursuant thereto, granted to an Eligible Person who dies, may not be exercised by the legal personal representatives of the estate of the Optionee at any time after the earlier of (i) the expiry of the Option in accordance with its terms, and (ii) the end of a period of 18 months after the date of the Optionee's death.

5.2 Subject to 5.3, an Option, and all rights to purchase Shares pursuant thereto, granted to an Eligible Person who subsequently ceases to be an Eligible Person because of retirement or resignation from the Corporation or a Subsidiary or the termination of the employment of such Eligible Person with the Corporation or a Subsidiary, with or without cause, may not be exercised by such Optionee at any time after the earlier of (i) the expiry of the Option in accordance with its terms, and (ii) the end of a period of 30 days from the date the Optionee so ceased to be an Eligible Person.

5.3 An Option, and all rights to purchase Shares pursuant thereto, granted to an Eligible Person who subsequently ceases to be an Eligible Person by reason of retirement or resignation from the Corporation or a Subsidiary at or after normal retirement age, may be exercised by the Optionee at any time prior to but not later than the earlier of (i) the expiry of the Option in accordance with its terms, and (ii) the end of a period of four years from the date the Optionee so ceased to be an Eligible Person.  The Board may at any time, in its sole discretion, determine that any particular Option, (vested or unvested) and all rights to purchase Shares pursuant thereto, granted to an Eligible Person who subsequently ceases to be an Eligible Person by reason of retirement or resignation from the Corporation or a Subsidiary prior to normal retirement age or the termination of the employment of such Eligible Person with the Corporation or a Subsidiary, with or without cause, may be exercised by the Optionee at any time prior to but not later than the earlier of (i) the expiry of the Option in accordance with its terms and (ii) the end of a period, specified by the Board at the time of such determination, not exceeding four years from the date the Optionee so ceased to be an Eligible Person.  For greater certainty, the Board may in its sole discretion make any such determination with respect to all or any part of the Options granted to any Eligible Person who has so ceased to be an Eligible Person.

5.4 Options shall not be affected by any change of employment or office of the Optionee where the Optionee continues to be a full-time employee or a director of the Corporation or any of its Subsidiaries.

ARTICLE 6

Exercise of Options

6.1 Subject to the other provisions of the Plan, an Option may be exercised from time to time by delivery to the Corporation at its head office of a written notice of exercise addressed to the Secretary of the Corporation specifying the number of Shares with respect to which the Option is being exercised and accompanied by payment in full of the Option Price for the Shares then being purchased.  Certificates for such Shares shall be delivered to the Optionee within a reasonable time following the receipt of such notice and payment.

6.2 Notwithstanding any of the provisions contained in the Plan or in any Option, the Corporation's obligation to issue shares to an Optionee pursuant to the exercise of an Option shall be subject to:  (a) completion of such registration or other qualifications of such Shares or obtaining approval of such governmental authority as the Corporation shall determine to be necessary or advisable in connection with the authorization, issuance or sale thereof; (b) the admission of such Shares to listing on any stock exchange on which the Shares may then be listed; and (c) the receipt from the Optionee of such representations, agreements and undertakings as to future dealings in such Shares as the Corporation determines to be necessary or advisable in order to safeguard against the violation of the securities laws of any jurisdiction.  In this connection, the Corporation shall to the extent necessary, take all reasonable steps to obtain such approvals, registrations and qualifications as may be necessary for issuance of such Shares in compliance with applicable securities laws and for the listing of such Shares on any stock exchange on which the Shares are then listed.  The Corporation may endorse such legend or legends upon the certificates for Shares issued pursuant to the exercise of an Option and may issue such "stop transfer" instructions to its transfer agent in respect of such Shares as the Board, in its sole discretion, determines to be necessary or appropriate to:

(a)          prevent a violation of, or to comply with the procedures for an exemption from, the prospectus or registration requirements of applicable securities laws,

(b)          or implement the provisions of this Plan and any agreement between the Corporation and the Optionee with respect to such Shares.

6.3 The Corporation may require an Optionee exercising an Option granted under this Plan, or disposing of shares acquired pursuant to the exercise of an Option, to reimburse the Corporation of or its applicable Subsidiary, for any taxes required by any governmental regulatory authority to be withheld or otherwise deducted and paid by the Corporation or its applicable Subsidiary in respect of the issuance or disposition of such Shares.  In lieu thereof, the Corporation or its applicable Subsidiary, as the case may be, shall have the right to withhold the amount of such taxes from any other sums due to become due from the Corporation or any of its Subsidiaries to the Optionee upon such terms and conditions as the Board shall prescribe.  The Corporation may, in its discretion, hold the share certificate to which such Optionee is entitled upon the exercise of an Option as security for the payment of such withholding tax liability, until cash sufficient to pay that liability has been accumulated.

ARTICLE 7

Certain Adjustments

7.1 Subject to section 7.2, appropriate adjustments in the number of Shares subject to the Plan and, as regards Options granted or to be granted, in the number of Shares optioned and in the Option Price, shall be made by the Board to give effect to adjustments in the number of Shares resulting from a Share Reorganization or other relevant changes in the share capital of the Corporation.

7.2 If and whenever there shall be a Capital Reorganization, any Optionee who exercises an Option after the effective date of the Capital Reorganization (which, in the case of a Capital Reorganization that is a compulsory acquisition of Shares following a take-over bid or issuer bid pursuant to section 206 of the Canada Business Corporations Act, shall be deemed to be the date on which such take-over bid or issuer bid expired) shall be entitled to receive, and shall accept, for the same aggregate Option Price, in lieu of the number of Shares to which such Optionee was therefore entitled upon such exercise, the aggregate amount of cash, shares, other securities or other property which such holder would have been entitled to receive as a result of such Capital Reorganization if, on the effective date thereof, the Optionee had been the registered holder of the number of Shares to which the Optionee was therefore entitled upon such exercise.

ARTICLE 8

Amendment or Discontinuance of Plan

8.1          The Board may, from time to time, amend the Plan, provided that no amendment shall be made without the approval of the Shareholders of the Corporation that will:

(a)          increase the total number of Shares reserved for Options under the Plan (other than an increase resulting from an adjustment provided for in section 7.1),

(b)          reduce the Option Price of any Option granted hereunder (other than adjustments provided for in Section 7.1 hereof), or

(c)          modify the provisions of the Plan relating to eligibility if such modifications would have the potential of broadening or increasing insider participation.

The rights and obligations under any Options granted before amendment of the Plan or any unexercised portion of such option shall not be adversely affected by amendment of the Plan or the Option without the consent of the holder of such Option.

ARTICLE 9

Miscellaneous Provisions

9.1 The holder of an Option shall not have any rights as a shareholder of the Corporation with respect to any of the Shares covered by such Option until the issuance of a certificate for Shares upon the exercise of such Option, in full or in part, and then only with respect to the Shares represented by such certificate or certificates.

9.2 Nothing in the Plan or any Option shall confer upon any Optionee any right to continue in the employ of the Corporation or any of its Subsidiaries or to continue to be an officer, director, or management nominee for election as a director, of the Corporation or any of its Subsidiaries or affect in any way the right of the Corporation or any such Subsidiary to terminate his or her employment at any time; nor shall anything in the Plan or any Option be deemed or construed to constitute an agreement or an expression of intent, on the part of the Corporation or any such Subsidiary to extend the employment of any Optionee beyond the time which he or she would normally be retired pursuant to the provisions of any present or future retirement plan or policy of the Corporation or any such Subsidiary, or beyond the time at which the Optionee would otherwise be retired pursuant to the provisions of any contract of employment with the Corporation or any such Subsidiary.

ARTICLE 10

Shareholders' and Regulatory Approval

10.1          The Plan shall be subject to the approval of the shareholders of the Corporation to be given by resolution passed at a meeting of the shareholders of the Corporation and to all requisite acceptances by The Toronto Stock Exchange.  Any Options granted prior to such approval and acceptance shall be conditional upon such approval and acceptance being given and no such Options may be exercised unless such approval and acceptance is given.
