THE ARRANGEMENT

Subject to the terms of the Arrangement Agreement, this Plan of Arrangement will become effective at the Effective Time (except as otherwise provided herein) and will be binding from and after the Effective Time on: (i) the Company; (ii) the Acquiror; (iii) all holders and all beneficial owners of Shares; (iv) all holders and all beneficial owners of Options; (v) the registrar and transfer agent in respect of the Shares; and (vi) the Depository.

On the Effective Date and commencing at the Effective Time, the following shall occur and be deemed to occur in the following order without further act or formality:

C-5

At the time of mailing the Proxy Circular or as soon as practicable after the Effective Date, the Company shall forward to each Shareholder and Optionholder at the address of such holder as it appears on the register maintained by or on behalf of the Company in respect of the holders of Shares or Options, as the case may be, the Letter of Transmittal in the case of holders of Shares and instructions for obtaining delivery of that portion of the Purchase Price or the Option Consideration, as the case may be, payable to such holder following the Effective Date pursuant to this Plan of Arrangement.

Prior to the Effective Date, (i) the Acquiror shall deposit, or arrange to be deposited, the money required for the payment of the aggregate Cash Proceeds per Share (the “Purchase Price”) for the Shares acquired pursuant to Section 2.2(5) for the benefit of and in trust for the holders of Shares entitled to receive Cash Proceeds per Share for each Share held by them in a special account with the Depository to be paid to or to the order of the respective former holders of such Shares without interest, and (ii) the Company shall deposit the money required for the payment of the aggregate Option Consideration for the Options which are acquired by the Company for cash pursuant to Section 2.2(3) for the benefit of and in trust for the holders of such Options in a special account with the Depository to be paid to or to the order of the respective former holders of such Options without interest. All such money shall be cash, denominated in Canadian dollars in same day funds payable at Toronto, Ontario. Such money shall not be used for any purpose except as provided in this Plan of Arrangement. Such payment to or to the order of the aforesaid former holders shall be made on presentation and surrender at the principal office of the Depository in the City of Toronto of, in the case of Shares, the certificate(s) representing the Shares which were acquired by the Acquiror pursuant to Section 2.2(5), and a duly completed Letter of Transmittal and such other documents and instruments, if any, as the Acquiror and/or the Depository may reasonably require. Upon surrender to the Depository for transfer to the Acquiror of, in the case of a Shareholder, a

C-6

certificate which immediately prior to the Effective Time represented Shares in respect of which the holder is entitled to receive cash under the Arrangement, and a duly completed Letter of Transmittal, and such other documents and instruments as would have been required to effect the transfer of the Shares formerly represented by such certificate under the CBCA and the by-laws of the Company and such additional documents and instruments as the Acquiror and the Depository may reasonably require, such former holder shall be entitled to receive in exchange therefor, and as soon as practicable after the Effective Time the Depository shall deliver to such holder, by cheque (or, if required by applicable laws, a wire transfer) for the amount of cash such holder is entitled to receive under the Arrangement (together, if applicable, with any unpaid dividends or distributions declared on the Shares, if any, prior to the Effective Time). In the event of a transfer of ownership of Shares that was not registered in the securities register of the Company, the amount of cash payable for such Shares under the Arrangement may be delivered to the transferee if the certificate representing such Shares is presented to the Depository as provided above, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable share transfer taxes have been paid. As soon as practicable after the Effective Time, the Depositary shall deliver on behalf of the Company to each Optionholder, as reflected on the books and records of the Company, a cheque (or, if required by applicable laws, a wire transfer) for the amount of cash such Optionholder is entitled to receive under the Arrangement in accordance with Section 2.2(3). Thereafter, the Acquiror and the Company shall be fully and completely discharged from their obligation to pay the Purchase Price to the former holders of such Shares and the aggregate Option Consideration to former holders of Options referred to in Section 2.2(5) and 2.2(3), respectively, and the rights of such holders shall be limited to receiving, without interest, from the Depository their proportionate part of the money so deposited on, in case of Shareholders, presentation and surrender of the documentation specified above. Any interest on such deposit shall belong to the Acquiror.

Any amounts deposited with the Depository for the payment of the Purchase Price or the aggregate Option Consideration which remain unclaimed on the date which is six years from the Effective Date shall be forfeited to the Acquiror and paid over to or as directed by the Acquiror and the former holders of Shares and/or Options shall thereafter have no right to receive their respective entitlement to the Purchase Price or the aggregate Option Consideration, as applicable.

If the Company declares, sets aside or pays any dividend on, or makes any other actual, constructive or deemed distribution in respect of any of the Shares, or otherwise makes any payments to the holders of the Shares in their capacity as such, during the period commencing on the date of the Arrangement Agreement and ending on the Effective Date, the Acquiror may reduce the amount of the Cash Proceeds per Share by any amount it determines in its sole discretion, provided that such discount shall not exceed the amount of such dividend, distribution or payment received per Share. No dividend or other distribution declared or made after the Effective Time with respect to

C-7

the Shares with a record date after the Effective Time shall be delivered to the holder of any unsurrendered certificate which, immediately prior to the Effective Time, represented outstanding Shares.

Any transfer of securities pursuant to this Plan of Arrangement shall be free and clear of any Liens.
