Key milestone achieved in TSX Group Inc./MX combination

FEBRUARY 13, 2008 (Toronto) – Shareholders of Montréal Exchange Inc. today voted 99.6% in favour of the combination with TSX Group Inc. to form TMX Group Inc., as announced December 10, 2007.

“This is a significant step towards completing the transaction,” said Michael Ptasznik, Interim Co-CEO, TSX Group. “Our efforts are now focused on obtaining the necessary regulatory approvals needed to finalize the combination.”

On February 1, 2008, the Autorité des marchés financiers (AMF) published MX’s application for an amendment to its recognition order to permit the transaction to be completed. TSX Group has provided important undertakings in conjunction with that process. The comment period is open until March 3, 2008 and will be followed by public hearings in Montreal on March 26 and 27, 2008.

“We believe the combination will provide great benefits for shareholders, Quebec and Canadian capital markets, added Mr. Ptasznik, “We are pleased that the AMF comment period is open and hearings have been scheduled. While we may not be able to close by March 31, 2008, we do hope to complete the transaction as soon as possible after the public hearings and receiving the AMF's decision and all other approvals."
