No insider trading

MONTREAL, Dec. 14 /CNW Telbec/ - Montreal Exchange Inc. (MX) (TSX: MXX) responded today to unfounded allegations of insider trading in respect of certain of its officers and directors.

At the time the transactions took place, MX was not in discussions or negotiations with any party in respect of a merger or other transaction. Furthermore, the transactions took place between fully informed insiders; therefore, no insider trading was possible.

The transactions in question occurred on August 2, 2007 and related to the purchase of MX shares by certain insiders of MX, including Mr. Jean Turmel, the Chairman of MX, and Mr. Luc Bertrand, the CEO of MX, from two other executives and insiders of MX, who had announced their departure from the company. The transactions were duly executed.
