MAPLE AND TMX GROUP NOTE PUBLICATION OF ALBERTA SECURITIES COMMISSION STAFF NOTICE

Maple Group Acquisition Corp. and TMX Group Inc. have noted the publication of a staff notice and accompanying news release by the Alberta Securities Commission with respect to the ASC's continued review of Maple's proposed acquisition of TMX Group and related transactions.

The staff notice and news release indicate that ASC staff have reviewed the Maple proposal as it relates to the ASC's oversight of Toronto Stock Exchange, TSX Venture Exchange and Natural Gas Exchange, and that the ASC expects to amend and restate its recognition orders for TSX-V and NGE and its exemption order for TSX in accordance with Maple's application. This is subject to a review by the ASC of any further changes to Maple's proposal, any changes to the recognition or exemption orders proposed by the Ontario Securities Commission, and the Autorite des marches financiers and the pending proposed recognition and exemption orders from the British Columbia Securities Commission.

The ASC further indicated its intention is to co-ordinate the issuance of its final orders with the other securities regulators.

The ASC staff notice 21-702 can be found on-line.

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 regulatory authorities 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.

Maple's offer to acquire a minimum of 70 per cent and a maximum of 80 per cent of the shares of TMX Group for $50 in cash per share is open until 5 p.m. (Eastern Time) on Thursday, May 31, 2012. Maple expects to have further information about the timing for receipt of potential final regulatory approvals by May 31, 2012, at which time it expects to further extend its offer to the date on which it expects to take up shares of TMX Group under the offer. Maple has agreed, under its support agreement with TMX Group, to continue to extend the expiry date of the offer until July 31, 2012, if necessary to obtain the required regulatory approvals. The offer is part of an integrated acquisition transaction, valued at approximately $3.8-billion, to acquire 100 per cent of TMX Group shares. The TMX Group board of directors continues to unanimously recommend that TMX Group shareholders accept and tender their shares under the Maple offer.

Details of Maple's offer are available in its offer and circular dated June 10, 2011, as varied by the notice of variation dated June 24, 2011, the notice of change and extension dated Aug. 8, 2011, the notice of extension dated Sept. 29, 2011, the notice of variation and extension dated Oct. 31, 2011, the notice of extension dated Jan. 31, 2012, the notice of extension dated Feb. 24, 2012, the notice of extension dated March 30, 2012, and the notice of change and extension dated May 3, 2012.
