The offer is part of an integrated acquisition transaction, valued at approximately $3.8 billion, to acquire 100% of TMX Group shares. The TMX Group Board of Directors continues to unanimously recommend that shareholders accept and tender their shares under the Maple offer.

If all required regulatory approvals are obtained prior to July 31, 2012, Maple expects to be in a position to take up TMX Group shares deposited under the offer on July 31, 2012, subject to the satisfaction of the minimum tender condition and the satisfaction or waiver of the other conditions of the offer.

Additional Information
As previously disclosed, under the support agreement with TMX Group, Maple has agreed to use commercially reasonable efforts to obtain all required regulatory approvals, including from the securities regulators and the Commissioner of Competition, and to accept all conditions, commitments and undertakings necessary to do so, provided they do not result in a "Material Detriment" as defined in the support agreement. Maple will continue to work to settle the terms and conditions of the required recognition orders and to resolve outstanding issues and concerns raised by securities regulators and the Commissioner of Competition. However, there can be no assurance that the terms and conditions of such final recognition orders will not result in a Material Detriment or that remedies short of a Material Detriment will address the issues and concerns raised by securities regulators and the Commissioner of Competition. As a result, there can be no assurance that the required regulatory approvals will be obtained.
