The bid is planned to commence on March 3^rd, 2011 and is due to terminate on March 2^nd, 2012.

The 2011 repurchase program represents $200 million in cash flow generation and cash-on-hand, and in addition up to $245 million from the remaining undistributed net proceeds from the Maidstone Bakeries sale in October 2010. The net proceeds of $400 million from that sale, after taxes and $30 million allocated to restaurant owners, is expected to be distributed in its entirety by the end of the third quarter of 2011.

Tim Hortons may discontinue purchases at any time, subject to compliance with applicable regulatory requirements. Shares purchased pursuant to the share repurchase program will be cancelled.

The maximum number of shares that may be purchased during any trading day may not exceed 25% of the average daily trading volume on the TSX, excluding purchases made by Tim Hortons under its current normal course issuer bid, based on the previous six completed calendar months, for a daily total of 93,920 common shares. This limit, for which there are permitted exceptions, is determined in accordance with regulatory requirements.
