On the Closing, the Undersigned will place his KMK Shares and duly executed stock powers of attorney with Xxxxx Xxxxxxx & Xxxxxxx LLP under a written escrow agreement, in form substantially the same as the escrow agreement to be signed by Xxxx Xxx, whereby compliance with this section 3 will be provided for. The restrictions in this section 3 will no longer apply in the event of a take-over bid made to all KMK shareholders or if there is a change of control of KMK.

(b)      During the Cooperative Period, the Undersigned will not dispose of more than the number of KMK Shares set out on Schedule A (“Monthly Sale”) in any 30 consecutive days (non-cumulative) except as further provided in this section 3.

(c)      If, during the Cooperative Period, the Undersigned wishes to sell or otherwise dispose of any shares in excess of the Schedule A amount per month, then up to twice per year the Undersigned must advise KMK in writing of such intention and offer up to the number of shares on Schedule A (“Semi-Annual Sale”) of those shares to KMK on substantially the same terms as it proposes to sell them through a stock exchange or otherwise and must offer them at a price which is 95% of the volume-adjusted average closing price during 5 days before the date of notice. KMK, or its nominee, has the right to accept such offer to sell within five business days of receipt of the notice, failing which the Undersigned shall be free, to sell that number of shares on the stock market. The Undersigned shall be entitled to exercise this election twice per 365 day period commencing from the date of Closing.

(d)      During the Cooperative Period, the Undersigned shall agree that with respect to all KMK Shares received under the Merger he shall vote such shares at each KMK shareholders’ meeting held or convened during the Cooperative Period, in favour of the proposals and resolutions recommended by management of KMK in its formal proxy circular providing the proposal or resolution are reasonable and in compliance with all Canadian laws and security acts. Notwithstanding this covenant, the Undersigned shall be free to

vote his KMK Shares in his own discretion, in respect of any proposed merger of KMK or in connection with the transaction which would constitute a change of control of KMK.

(e)      During the Cooperative Period, the Undersigned shall be entitled to a pre-emptive right to take up his pro rata share of any new securities to be sold by KMK on substantially the same terms as such securities are offered to third parties. The Undersigned must confirm his preparedness to participate in such treasury offerings within 15 days of receipt of notice of the offering. Excluded from this pre-emptive right shall be KMK securities which are allotted or issued for stock options, property acquisitions and securities issued on exercise of options, warrants and property commitments as of the Closing.

(f)      During the Cooperative Period, KMK, using reasonable endeavours, will assist the Undersigned, upon the request of the Undersigned, in disposing on a one time basis, of up to the number of Shares on Schedule A (“One Time Sale”), less the number of shares sold prior to such request under any other paragraph in this section 3 (i.e. monthly or semi-annual sale amounts). The Undersigned will provide 30 days’ notice of the worth of the number of shares he desires to dispose of and KMK will assist to find a buyer for such shares at a price of no less than the prevailing market price of KMK Shares at the time the notice is given by the Undersigned (the price shall be set at 90% of the volume-adjusted average closing price during 10 days before the date of notice). The purchase and sale of such shares shall close within the 30-day notice period and the Undersigned is obligated to provide marketable certificates, free of hold period restrictions or any other encumbrances.
