TORONTO, March 30, 2012 /PRNewswire/ – Maple Group Acquisition Corporation
(“Maple”), a corporation whose investors comprise 13 of Canada’s
leading financial institutions and pension funds, and TMX Group Inc.
(“TMX Group”) (TSX:X), today announced the extension of Maple’s offer
to acquire a minimum of 70% and a maximum of 80% of the shares of TMX
Group to 5:00p.m. (Eastern Time) on Monday, April 30, 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further extended or withdrawn.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.

Today’s announcement follows progress announced by Maple and TMX Group
on March 15, 2012 that the Autorit des march s financiers (“AMF”)
intends to approve the Maple transaction and that the Ontario
Securities Commission (“OSC”) has informed Maple that it has requested
its staff to develop draft recognition orders with detailed terms and
conditions required by the OSC. The draft orders will be published for
a 30-day public comment period in the near future.

As previously disclosed, under the support agreement, 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 work to settle the terms and conditions of the
recognition orders and to resolve outstanding issues and concerns
raised by the securities regulatory authorities and the Competition
Bureau. However, there can be no assurance that the terms and
conditions of the 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 the securities regulatory authorities
and the Commissioner of Competition. As a result, there can be no
assurance that the required regulatory approvals will be obtained.

Given the current status of the regulatory approvals, it is apparent
that the offer will not be completed by April 30, 2012, which is the
outside date under the support agreement between Maple and TMX Group,
and the expiry date under the acquisition governance agreement between
the Maple investors and the debt facilities committed to Maple to fund
the Maple transaction. The Maple investors are in active negotiations
among themselves and with Alpha and the Canadian Depository for
Securities Limited (“CDS”) and certain other shareholders of Alpha and
CDS, but have not yet reached agreement among themselves, or as
applicable with Alpha and CDS and those other shareholders, as to the
price or terms of these acquisitions. Under the support agreement Maple
agreed to use commercially reasonable efforts to enter into definitive
agreements for the acquisition of Alpha and CDS prior to the completion
of the Maple offer. Under the acquisition governance agreement between
the Maple investors, each Maple investor has also agreed to use
commercially reasonable efforts to pursue and effect the acquisitions
concurrently with or as soon as practicable following completion of the
Maple offer, including to negotiate in good faith the price and other
terms and conditions of those acquisitions.

In considering any further extensions of the offer beyond April 30,
2012, Maple will review and assess the progress of its discussions with
securities regulators and the Competition Bureau in respect of the
regulatory approvals, its discussions with Alpha, CDS and their
security holders in respect of the acquisitions of Alpha and CDS, as
well as all other circumstances affecting the Maple transaction. It is
Maple’s current intention to further extend the offer on or before
April 30, 2012 if Maple is satisfied with those matters. Therefore, as
announced on March 15, 2012, Maple and TMX Group are in discussions
regarding an extension of the outside date under the support agreement,
and Maple is in discussions concerning the extension of related
agreements among the thirteen Maple investors and with its lenders in
respect of the extension of the debt financing to be used to fund the
acquisition. However, there can be no assurance at this time that the
offer will be further extended.

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 August 8, 2011, the
Notice of Extension dated September 29, 2011, the Notice of Change and
Extension dated October 31, 2011, the Notice of Extension dated January
31, 2012, the Notice of Extension dated February 24, 2012, and a
further Notice of Extension to be filed by Maple on SEDAR and mailed to
TMX Group’s shareholders in respect of the extension of the offer
announced today. These documents are also available at www.abetterexchange.com.

Securities Exchange Act of 1934, as amended (the “U.S. Exchange Act”).
Accordingly, the offer is not subject to Section 14(d) of the U.S.
Exchange Act, or Regulation 14D promulgated by the U.S. Securities and
Exchange Commission (the “SEC”) thereunder. The offer is being

law of any state or other jurisdiction of the United States. The Maple
shares to be issued pursuant to the plan of arrangement will be issued
in reliance upon the exemption from the registration requirements of
the U.S. Securities Act provided by section 3(a)(10) thereof and only
to the extent that corresponding exemptions from the registration or
qualification requirements of state “blue sky” securities laws are
available.
