NO OBLIGATION TO EXERCISE OPTION. The granting of an option shall not impose any obligation upon the optionee to exercise such option.

The Option Period for an Option will be determined by the Committee at the time the Option is granted and may be up to 10 years from the date the Option is granted. At the time an Option is granted, the Committee may determine that, with respect to that Option, upon the occurrence of one of the events described in [subsection 10.1] there will come into force a time limit for exercise of such Option which is different than the Option Period, and in the event of such a determination, the Option Agreement for such Option will contain provisions which specify the events and time limits related to that determination. Subject to the applicable maximum Option Period provided for in this [subsection 8.1] and subject to applicable regulatory requirements and approvals, the Committee may extend the Option Period of an outstanding Option beyond its original expiration date, provided that shareholder approval, including disinterested shareholder approval if required by the TSX, is obtained for any extension of the Option Period of an outstanding Option.

The Company may exercise the Purchase Option by delivering or mailing to the Participant (or the Participant’s estate), within 180 days after the termination of the Service of the Participant, a written notice of exercise of the Purchase Option. Such notice shall specify the number of Shares to be purchased. If and to the extent the Purchase Option is not so exercised by the giving of such a notice within such 180-day period, the Purchase Option shall automatically expire and terminate effective upon the expiration of such180-day period.
