TORONTO, July 11, 2012 - Maple Group Acquisition Corporation ("Maple") and TMX Group Inc. ("TMX Group") (TSX:X) today announced that the British Columbia Securities Commission ("BCSC") and Alberta Securities Commission ("ASC") have approved final recognition orders with respect to Maple's proposed acquisition of TMX Group and TSX Venture Exchange and that the BCSC has approved a final recognition order with respect to Maple's proposed acquisition of The Canadian Depository for Securities Limited ("CDS") and that the ASC has approved a variation order for the Natural Gas Exchange. These orders provide the terms under which the BCSC and ASC will permit Maple to operate a combined exchange and clearing group. Maple has agreed to the terms of these orders.

The final BCSC and ASC recognition orders reflect a commitment by Maple to the continued success of the TSX Venture Exchange and the Natural Gas Exchange, including formal governance commitments that provide for a significant role on the TSX Venture Exchange Board of Directors and the Maple Board of Directors for individuals with public venture market expertise. TSX Venture will also maintain national and local public venture advisory committees that will be comprised of participants in the Canadian public venture capital market and that will provide advice and recommendations to the board of directors of TSX Venture Exchange on all policy, operational and strategic issues that are likely to have a significant impact on the Canadian public venture market.

On July 4, 2012, Maple and TMX Group announced that they had obtained final recognition orders for their transaction from the Ontario Securities Commission ("OSC") and Autorité des marchés financiers ("AMF"), and that it has received a "no action" letter from the Competition Bureau.

Speaking on behalf of Maple, Luc Bertrand said, "The publication of recognition orders from the British Columbia and Alberta Securities Commissions establishes the terms under which they will permit us to operate our integrated exchange and clearing group. This sets the stage for Maple to take up TMX Group shares under its offer on July 31, and we now strongly urge TMX Group shareholders to deposit and tender their shares to our offer before it expires on July 31."
Tom Kloet, Chief Executive Officer, TMX Group said, "I'd like to thank the BCSC and ASC, and all regulators across Canada, for their hard work on this file. Following completion of the transaction, TMX Group will be a stronger organization, able to introduce new innovation and efficiency to the Canadian market, and to grow, compete and win more effectively on the global stage. We look forward to a successful conclusion of the tendering process and to the work ahead to bring our plans to fruition."

Offer to TMX Group shareholders

Maple's offer to acquire a minimum of 70% and a maximum of 80% of the shares of TMX Group for $50 in cash per share is open until 5:00p.m. (Eastern Time) on Tuesday, July 31, 2012, unless further extended or withdrawn. 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.

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, including receipt of the remaining required regulatory approvals. Maple is also seeking to complete the proposed acquisitions of Alpha and CDS concurrently with or as soon as possible following the completion of the Maple offer.

Minimum and Full Deposit Elections

Maple's offer includes a minimum tender condition that requires 70% of TMX Group shares outstanding be deposited to the offer. Maple recognizes TMX Group shareholders who support the offer may also want to retain as many of their TMX Group shares as possible in order to participate in the successor company and its ongoing upside potential. Accordingly, the offer includes a "minimum deposit" election designed to provide TMX Group shareholders with the opportunity to support Maple's transaction by having only the minimum number of TMX Group shares acquired for cash while still satisfying the minimum tender condition.

Shareholders that support the Maple Acquisition should accept the Offer, tender their TMX Shares under the Offer and make either the Full Deposit Election or the Minimum Deposit Election.

Shareholders that would like to receive as much cash as possible for their TMX Shares pursuant to the Maple Acquisition should make the Full Deposit Election.

Shareholders that would like to support the Offer but would like to receive as many Maple Shares as possible for their TMX Shares pursuant to the Maple Acquisition should make the Minimum Deposit Election.
