Canadian Warrants

Warrants may be exercised at any time during the period commencing at market open (Toronto time) on July 20, 2010, and ending at the expiry date. Warrants not exercised prior to the expiry date will be void and of no value.

The company uses the book-entry-only system administered by CDS with respect to the Class A shares, preferred shares and warrants. A holder of warrants may subscribe for units by instructing the CDS participant holding the subscriber's warrants to exercise all or a specified number of such warrants and forwarding the subscription price for each unit subscribed for to such CDS participant.

A holder of warrants may subscribe for a whole number of units by instructing the CDS participant holding the subscriber's warrants to exercise all or a specified number of such warrants and forwarding the subscription price for each unit subscribed for in accordance with the terms of the offering and the warrant indenture to the CDS participant which holds the subscriber's warrants.

The entire subscription price for units subscribed for must be paid at the time of subscription and must be received by the warrant agent prior to the date of the exercise of the warrants. Accordingly, a subscriber subscribing through a CDS participant must deliver its payment and instructions sufficiently in advance of the expiry date to allow the CDS participant to properly exercise the warrants on such subscriber's behalf. Units will be issued on a fully paid basis only. Class A shares and preferred shares not issued prior to the closing of the record on a distribution record date will not be eligible to receive the applicable distribution. Holders of warrants are encouraged to contact their broker or other CDS participants as each CDS participant may have an earlier cut-off time.

Each holder of warrants that subscribes for units to which such holder is entitled pursuant to the basic subscription privilege may, at any time during the exercise period, subscribe for additional units pursuant to the additional subscription privilege, if applicable, at a price equal to the subscription price for each additional unit. Holders of warrants will not be required to fully exercise all of their warrants under the basic subscription privilege in order to be eligible for the additional subscription privilege.

To apply for additional units under the additional subscription privilege, a beneficial holder of warrants must forward his or her request to a CDS participant. Payment for additional units must accompany the request when it is delivered to the CDS participant. Accordingly, the subscriber must deliver payment and instructions sufficiently in advance of the expiry date to allow the CDS participant to properly exercise warrants on such subscriber's behalf and apply for additional units under the additional subscription privilege, as applicable. Payment in full of the subscription price must be received by the warrant agent prior to 5 p.m. (Toronto time) on the expiry date, failing which the subscriber's entitlement to such units will terminate. Any excess funds will be returned by mail or credited to a subscriber's account with its CDS participant, without interest or deduction. Units will be issued on a fully paid basis only.

Holders of warrants are encouraged to contact their broker or other CDS participants as each CDS participant may have an earlier cut-off time. Holders of warrants who wish to exercise their warrants and receive Class A shares and preferred shares are reminded that because warrants must be exercised through a CDS participant, a significant amount of time may elapse from the date of exercise and the date the Class A shares and preferred shares issuable upon the exercise thereof are issued to the holder.

The Class A shares and preferred shares are not registered under the 1933 act. The offering is made in Canada and not in the United States. The offering is not, and under no circumstances is to be construed as, an offering of any Class A shares and preferred shares for sale in the United States or an offering to or for the account or benefit of any U.S. person or a solicitation therein of an offer to buy any securities. Accordingly, the warrants may not be distributed to shareholders located in the United States, and no subscriptions will be accepted from any person, or their agent, who appears to be, or who the company has reason to believe is, resident in the United States. Each CDS participant will, prior to the expiry date, attempt to sell for the U.S. Class A shareholders the warrants allotable to such U.S. Class A shareholders at the price or prices it determines in its discretion. Any proceeds received by the CDS participant with respect to such warrants are expected to be delivered by the CDS participant as soon as practicable to such U.S. Class A shareholders.

All Class A shareholders whose recorded address is outside of Canada, other than those Class A shareholders who confirm their eligibility to receive and exercise warrants, are advised that their warrants will be held by their CDS participant for the account of such Class A shareholders. The CDS participant will, prior to the expiry date, attempt to sell for such Class A shareholders the warrants allotable to such Class A shareholders at the price or prices it determines in its discretion. Any proceeds received by the CDS participant with respect to such warrants are expected to be delivered by the CDS participant as soon as practicable to such Class A shareholders.

The warrants will be governed by the terms of a warrant indenture to be dated July 19, 2010, between the company and Computershare Trust Company of Canada, as warrant agent. The warrant indenture provides for appropriate adjustments to the warrants in the event of stock dividends, subdivisions, consolidations and other forms of capital reorganization.

The company will pay a warrant exercise fee at the time the warrant is exercised equal to 31 cents per warrant to the CDS participant whose client is exercising the warrant. The warrant exercise fee payable is subject to a maximum of $2,500 per beneficial subscriber in respect of warrants exercised by or on behalf of any single beneficial subscriber pursuant to the basic subscription privilege.

The Toronto Stock Exchange has been advised the company has not retained the services of any securities dealer or broker to solicit subscriptions for shares and will not pay any fee or commission for soliciting such subscriptions.
