least three years of continuous service with the Company or any Subsidiary and
attaining the age of 62. Without limiting the generality of the foregoing, in no
event shall Retirement include the involuntary termination of the Grantees

clauses (b) and (c) shall not apply if the Optionee is residing in Canada. The requirement of
payment in cash shall be deemed satisfied if the Optionee shall have made arrangements

requirement be satisfied by retention by the Company of a portion of the shares purchased upon
exercise of this Option. If such election is made, the shares so retained shall be credited
against such withholding requirement at the Market Value per Share on the date of exercise.
In no event, however, shall the Company accept Common Shares for payment of taxes in excess of
required tax withholding rates.8.
