This notice shall state the intention of the Participant or the Participant's legal personal representative to exercise the said Option or a portion thereof, the number of Common Shares in respect of which the Option is then being exercised, and must be accompanied by payment in full of the Option Price for the Common Shares which are the subject of the exercise. 6. Adjustment in Shares 6.1 Appropriate adjustments in the number of Common Shares subject to the Plan and, as regards Options granted or to be granted, in the number of Common Shares optioned and in the Option Price, shall be made by the Board to give effect to adjustments in the number of Common Shares resulting from subdivisions, consolidations or reclassification of the Common Shares or other relevant changes in the authorized or issued capital of the Corporation. 6.2 Options granted to Participants hereunder are non-assignable and, except in the case of the death of a Participant (which is provided for in Section 8), are exercisable only by the Participant to whom the Options have been granted; provided that subject to the prior approval of the Board and the Exchange an Option may be assigned to a corporation controlled by the Participant and 100% beneficially owned by the Participant and his spouse or children, which control and ownership shall continue for as long as any part of the Option remains unexercised. 7. Decisions of the Board All decisions and interpretations of the Board respecting the Plan or Options granted thereunder shall be conclusive and binding on the Corporation and the Participants and their respective legal personal representative and on all directors, officers, employees and other persons eligible under the provisions of the Plan to participate therein. 8. Termination 8.1 If a Participant ceases to be any of a director, officer, employee or person providing services to the Corporation (other than death), he may within 30 days following his ceasing to be a director, officer, employee or person providing services to the Corporation the Participant may within 30 days of ceasing to be a director, officer, employee or person providing services to the Corporation, exercise his Option to the extent that he was entitled to exercise it at the date of such cessation. 8.2 In the event of the death of a Participant, the Option previously granted to the Participant will be exercisable only within 12 months following the death of the Participant and then only: (a) by the person or persons to whom the Participant's rights under the Option shall pass by the Participant's will or the laws of descent and distribution; and (b) if and to the extent that the Participant was entitled to exercise the Option at the date of death of the Participant. 8.3 The Plan does not confer upon a Participant any right with respect to continuation of employment by the Corporation or any Subsidiary, nor does it interfere in any way with the right of the Participant or the Corporation, a Subsidiary to terminate the Participant's employment at any time. 8.4 Options shall not be affected by any change of employment of the Participant where the Participant continues to be employed by the Corporation or any of its Subsidiaries. 9. Effect of Takeover Bid If a bona fide offer (the "Offer") for Common Shares is made to the Participant or to shareholders generally or to a class of shareholders which includes the Participant, which Offer, if accepted in whole or in part, would result in the offeror exercising control over the Corporation within the meaning of subsection 1(3) of the Securities Act (Ontario)(as amended from time to time), then the Corporation shall, immediately upon receipt of notice of the Offer, notify each Participant currently holding an Option of the Offer, with full particulars thereof; whereupon, such Option may be exercised in whole or in part by the Participant so as to permit the Participant to tender the Common Shares received upon such exercise (the "Optioned Shares") pursuant to the Offer. If: (a) the Offer is not completed within the time specified therein; or (b) the Participant does not tender the Optioned Shares pursuant to the Offer; or (c) all of the Optioned Shares tendered by the Participant pursuant to the Offer are not taken up and paid for by the offeror in respect thereof; then the Optioned Shares or, in the case of clause (c) above, the Optioned Shares that are not taken up and paid for shall be returned by the Participant to the Corporation and reinstated as authorized but unissued Common Shares and the terms of the Option as set forth in the Plan shall again apply to the Option. If any Optioned Shares are returned to the Corporation under this Section, the Corporation shall refund the exercise price to the Participant for such Optioned Shares. In no event shall the Participant be entitled to sell the Optioned Shares otherwise than pursuant to the Offer. 10. Effect of Amalgamation, Consolidation or Merger If the Corporation amalgamates, consolidates with or merges with or into another corporation any Common Shares receivable on the exercise of an Option shall be converted into the securities, property or cash which the Participant would have received upon such amalgamation, consolidation or merger if the Participant had exercised his Option immediately prior to the record date applicable to such amalgamation, consolidation or merger, and the Option Price shall be adjusted appropriately by the Board and such adjustment shall be binding for all purposes of the Plan. 11. Amendment or Discontinuance of Plan The Board may amend or discontinue the Plan at any time without the consent of the Participants provided that such amendment shall not alter or impair any Option previously granted under the Plan except as permitted by the provisions of Article 6 hereof. Any amendment of the Plan will require the prior approval of the Exchange and may require the approval of the Corporation's shareholders. 12. Government Regulation The Corporation's obligation to issue and deliver Common Shares under any Option is subject to: (a) the satisfaction of all requirements under applicable securities laws in respect thereof and obtaining all regulatory approvals as the Corporation shall determine to be necessary or advisable in connection with the authorization, issuance or sale thereof; (b) the admission of Common Shares to listing on any stock exchange on which such Common Shares may then be listed; and (c) the receipt from the Participant of such representations, agreements and undertakings as to future dealings in such Common 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 take all reasonable steps to obtain such approvals and registrations as may be necessary for the issuance of such Common Shares in compliance with applicable securities laws and for the listing of such Common Shares on any stock exchange on which such Common Shares are then listed. 13. Participant's Rights A Participant shall not have any rights as a shareholder of the Corporation until the issuance of a certificate for Common Shares upon the exercise of an Option or a portion thereof, and then only with respect to the Common Shares represented by such certificate or certificates. 14. Approvals 14.1 The Plan shall be subject to acceptance by the Exchange and compliance with all conditions imposed by the Exchange. 14.2 Any Options granted prior to such acceptance shall be conditional upon such acceptance being given and conditions complied with and no such Options may be exercised unless such acceptance is given and such conditions complied with. 15.
