4. Adjustment of Share Purchase Price

(a) If at any time in the twelve-month period following the date of this Agreement any person or group of persons acting jointly or in concert, including, for the avoidance of doubt, the Purchaser, acquires all or substantially all of the assets of the Corporation and its subsidiaries, taken as a whole, or acquires all of the common shares in the capital of the Corporation (the “Common Shares”) (any such transaction being a “Price Protection Transaction”) then, within five business days following completion of the Price Protection Transaction, the Purchaser shall pay, or cause an Affiliate to pay, to the Vendor, the Adjustment Payment (as defined below), if applicable, in immediately available funds.

(b) The “Adjustment Payment” will be equal to:

(c) If all or any portion of the Transaction Consideration is in the form of:

(i) cash, the consideration shall be valued based on the face value of the cash,

(ii) publicly traded securities, the consideration shall be valued based on the closing price of such securities on the date of the completion of the Price Protection Transaction on the published market on which the greatest volume of trading in such securities occurred over the twenty days preceding such date,

(iii) securities that are not publicly traded until the date of the completion of the Price Protection Transaction, the consideration shall be valued based on the closing price of such securities on the five trading days following the completion of the Price Protection Transaction on the published market on which the greatest volume of trading in such securities occurred over such period, or

(iv) any other consideration, the consideration shall be valued at its fair market value as the Vendor and the Purchaser shall mutually agree, acting reasonably.

(d) If all or any portion of the Transaction Consideration has a value expressed in a currency other than Canadian dollars, then the value of that consideration will be expressed in Canadian dollars based upon a conversion rate of exchange equal to the noon spot rate quoted by the Bank of Canada on the date of the completion of the Price Protection Transaction for the purchase of Canadian dollars using the currency in which the consideration (or portion thereof) was originally denominated.

(e) In the event of any disagreement between the parties with respect to the calculation of the Transaction Consideration, the matter will be submitted to an internationally recognized firm of chartered accountants independent of both parties and their Affiliates to be agreed upon by the parties.
