Effect of a Take-Over BidIf a bona fide offer (an "Offer") for Shares is made to the optionee or to shareholders of the Company generally or to a class of shareholders which includes the optionee, which Offer, if accepted in whole or in part, would result in the offeror becoming a control person of the Company, within the meaning of subsection 1(1) of the Securities Act, the Company shall, immediately upon receipt of notice of the Offer, notify each optionee of full particulars of the Offer, whereupon all Option Shares subject to such option will become Vested and the option may be exercised in whole or in part by the optionee so as to permit the optionee to tender the Option Shares received upon such exercise, pursuant to the Offer.  However, if:

the Offer is not completed within the time specified therein; or

(b)

all of the Option Shares tendered by the optionee pursuant to the Offer are not taken up or paid for by the offeror in respect thereof,

then the Option Shares received upon such exercise, or in the case of clause (b) above, the Option Shares that are not taken up and paid for, may be returned by the optionee to the Company and reinstated as authorized but unissued Shares and with respect to such returned Option Shares, the option shall be reinstated as if it had not been exercised and the terms upon which such Option Shares were to become Vested pursuant to this section shall be reinstated.  If any Option Shares are returned to the Company under this section 6.03, the Company shall immediately refund the exercise price to the optionee for such Option Shares.

6.04

Acceleration of Expiry DateIf at any time when an option granted under the Plan remains unexercised with respect to any Unissued Option Shares, an Offer is made by an offeror, the Directors may, upon notifying each optionee of full particulars of the Offer, declare all Option Shares issuable upon the exercise of options granted under the Plan, Vested, and declare that the Expiry Date for the exercise of all unexercised options granted under the Plan is accelerated so that all options will either be exercised or will expire prior to the date upon which Shares must be tendered pursuant to the Offer, provided such Offer is completed.

6.05

Effect of a Change of ControlIf a Change of Control occurs, all Option Shares subject to each outstanding option will become Vested, whereupon such option may be exercised in whole or in part by the optionee.

PART 8

AMENDMENT OF PLAN

8.01

Board May Amend  The Board may, by resolution, amend or terminate this Plan, but no such amendment or termination shall, except with the written consent of the optionees concerned, affect the terms and conditions of options previously granted under this Plan which have not then been exercised or terminated.
