TMX Group opened a trading window for employees on Thursday February 10, 2011, following disclosure of the company's fourth quarter and full year 2010 financial results, and following the announcement of TMX Group's plans to merge with London Stock Exchange Group plc. In accordance with TMX Group's Timely Disclosure Policy, this trading window is expected to remain open until March 3, 2011. After this trading window closes, optionholders (including reporting insiders) will be prevented from completing transactions involving the exercise of TMX Group options and subsequent sale of the underlying TMX Group common shares until the next trading window opens. It is currently unknown when that will occur. Therefore, certain optionholders may elect to exercise stock options during the current trading window, particularly where those options are set to expire in the current trading window.
Please note that our reporting insiders, among others, are obligated to hold minimum equity ownership levels.
