The tender offer is scheduled to expire at midnight, Eastern Time, on 16 June 2009 (the "Expiration Date"), unless extended or earlier terminated. The total consideration for each CAD 1000 principal amount of the Notes is CAD 1010 (the "Total Consideration"), which includes an early tender payment of CAD 10 per CAD 1000 principal amount of Notes (the "Early Tender Payment") and the Purchase Price (as defined below). The Early Tender Payment is payable only to holders of Notes who tender and validly deliver their Notes on or before 5:00 p.m., Eastern Time, on 01 June 2009 (the "Early Tender Time"), if such Notes are accepted for purchase by the company. Holders who tender their Notes after the Early Tender Time and on or before the Expiration Date will be entitled to receive CAD 1000 per CAD 1000 principal amount of the Notes (the "Purchase Price"), if such Notes are accepted for purchase by the company. Holders of Notes accepted for purchase by the company will also receive in addition to the Total Consideration or Purchase Price, as applicable, accrued and unpaid interest on any Notes so purchased from the last interest payment date to, but not including, the date on which the Notes are purchased. The company expects to accept the Notes for purchase promptly after the Expiration Date and expects that it will pay the Total Consideration or Purchase Price, as applicable, on the Notes on the business day following the date that the Notes are accepted. As of 19 May 2009, approximately CAD 540 million aggregate principal amount of the Notes were outstanding.

The company may increase or waive the Tender Cap at its sole discretion. If the aggregate principal amount of Notes validly tendered pursuant to the tender offer exceeds the Tender Cap, then, if the company accepts Notes for purchase, it will purchase such Notes on a pro rata basis among the tendering Holders of Notes, based on the aggregate principal amount of Notes tendered by each Holder. The company's obligation to consummate the tender offer is conditioned upon the satisfaction or waiver of certain conditions described in the Offer to Purchase (as defined below), including the company obtaining at least CAD 250 million in proceeds from an offering of debt securities, on terms and conditions reasonably satisfactory to the company, on or before the Expiration Date.
