  offer
• Offer remains open until 5:00 p.m. (Eastern time) on August 10

TORONTO, July 31, 2012 /CNW/ – Maple Group Acquisition Corporation
(“Maple”) and TMX Group Inc. (“TMX Group”) today announced that all of
the conditions to Maple’s offer to acquire up to 80% of the TMX Group
shares for $50 per share in cash (including the receipt of all regulatory approvals) have been satisfied
of the initial expiry of the Maple offer at 5:00 p.m. (Eastern time) on
July 31, 2012. Approximately 91% of the outstanding TMX Group shares
have been deposited under the offer, satisfying the minimum tender
condition. Maple has taken up all TMX Group shares deposited under the
offer in accordance with the terms thereof, and the offer has been
further extended for an additional 10-day period until 5:00 p.m.
(Eastern time) on August 10, 2012 (the “deposit extension period”).
The purpose of the deposit extension period is to provide those TMX
Group shareholders that have not yet deposited their TMX Group shares
under the offer an opportunity to receive cash in respect of a portion
of their TMX Group shares.

A new Board of Directors has been appointed for Maple, TMX Group and its
principal operating subsidiaries, and the new Board will name TMX Group
officers as officers of Maple. As disclosed in Maple’s Notice of Change
of Information filed on SEDAR on July 19, 2012, Chuck Winograd will
serve as the Chair of the Maple Board and the TMX Group Board, and Tom
Kloet will serve as Chief Executive Officer of both Maple and TMX
Group, in addition to serving on the Boards of Maple and TMX Group.

In addition to Mr. Winograd and Mr. Kloet, the other Directors, as
disclosed in Maple’s Notice of Change of Information dated July 19,
2012, are: Luc Bertrand, Denyse Chicoyne, Marie Giguère, George Gosbee,
William Hatanaka, Harry Jaako, William Linton, Jean Martel, William T.
Royan, Gerri Sinclair, Kevin Sullivan, Anthony Walsh, Eric M.
Wetlaufer, and Tom Woods.

Maple intends to complete the acquisitions of Alpha Trading Systems Inc.
and Alpha Trading Systems Limited Partnership (collectively, “Alpha”)
and The Canadian Depository for Securities Limited (“CDS”) on August 1,
2012. As previously announced, Maple will be renamed “TMX Group
Limited” on August 10, 2012.

Mr. Winograd made the following comment:

“It is a privilege to be invited to serve as Chair and to help guide
this great institution forward. In addition to being a successful
business with interesting growth opportunities, TMX Group plays a
central role in Canada’s capital markets and has an important public
interest mandate. I look forward to working with my fellow directors,
Tom Kloet and the management team, to advance the company’s goals and
enhance its contribution to the success of Canada’s public capital
markets.”

Mr. Kloet added:

“TMX Group is pleased with today’s outcome. Tomorrow, we will welcome
employees from CDS and Alpha to our organization and together we will
build an even stronger, more competitive company. We are excited by
the opportunities before us and are committed to serving all of our
clients with excellence and innovation in the months and years ahead.”

“I would also like to take this opportunity to thank our departing
directors for their years of service to TMX Group and for their
guidance and direction throughout this process. I would particularly
like to thank Wayne Fox. For over 15 years, 11 of them as Chair, he
provided leadership and direction to a number of CEOs and helped guide
this company through several important milestones. I am personally
grateful to him for his counsel and partnership over my time at TMX
Group and throughout the process that we have just concluded. I look
forward to working with the new Board, which includes new and
continuing Directors, to advance the company’s objectives.”

Speaking on behalf of Maple investors, Luc Bertrand said:

“We are very pleased with the level of support that shareholders have
shown for this transaction as well as for the integrated exchange and
clearing business proposition we have put forward. We also thank the
Canadian regulatory authorities for their rigour and diligence in
reviewing our proposal. The company will move forward with a new Board
that represents a cross-section of experience and knowledge reflecting
the importance of the company across the Canadian capital marketplace
and the commitments made to regulatory authorities. I look forward to
serving with my fellow Directors and to contributing to TMX Group’s
future success.”

Further Details

The Maple offer remains open for deposits until the expiry of the
deposit extension period at 5:00 p.m. (Eastern time) on August 10,
2012. Any TMX Group shareholder that wishes to receive cash
consideration for a portion of their TMX Group shares must deposit
their shares under the offer prior to such time and select the “Full
Deposit Election” in respect of such shares, failing which those TMX
Group shares will be acquired in exchange for Maple shares on a
one-for-one basis pursuant to the subsequent arrangement, as described
below.

Of the deposited TMX Group shares, approximately 83% of the outstanding
TMX Group shares were deposited under the Full Deposit Election made
available under the offer, and approximately 8% of the outstanding TMX
Group shares were deposited under the “Minimum Deposit Election”.

Since more than 70% of the outstanding TMX Group Shares have been
deposited under the offer under the Full Deposit Election, no TMX Group
Shares deposited under the Minimum Deposit Election will be acquired
under the Offer.

In addition, since more than 80% of the outstanding TMX Group shares
have been deposited under the offer under the Full Deposit Election,
the number of TMX Group shares to be acquired for $50 cash per TMX
Group share will be pro rated at the expiry of the deposit extension
period. If the applicable pro ration factor to be applied at the expiry
of the deposit extension period had been applied to the TMX Group
shares deposited as of 5:00 p.m. on July 31, 2012, approximately 96% of
the TMX Group shares subject to Full Deposit Elections would have been
acquired for $50 in cash per share, with the remaining approximately 4%
of the TMX Group shares deposited under such election being returned to
the depositing TMX Group shareholders and exchanged for Maple shares on
a one-for-one basis upon completion of the subsequent arrangement
described below. However, such percentages will not be finalized until
the expiry of the deposit extension period and will vary to the extent
that any additional TMX Group shares are deposited under the offer
under the Full Deposit Election during the deposit extension period.

Upon expiry of the deposit extension period, Maple will apply the
applicable pro-ration factor to TMX Group shares deposited prior to
such time under the Full Deposit Election and pay for those TMX Group
shares that are to be acquired. Shareholders should expect to receive
payment through the appropriate intermediaries during the week of
August 13, 2012. Any TMX Group shares deposited but not acquired under
the Maple offer (including those deposited under the Minimum Deposit
Election) will be returned to the depositing TMX Group shareholders
and, together with all TMX Group shares not tendered to the Maple
offer, will be exchanged for Maple shares on a one-for-one basis upon
completion of the subsequent arrangement described below.

Maple will use its best efforts to complete the subsequent arrangement
within 35 days following expiry of the deposit extension period. The
subsequent arrangement is a share exchange transaction pursuant to a
court-approved plan of arrangement under which the remaining TMX Group
shares held by TMX Group shareholders (other than Maple) will be
exchanged for common shares of Maple on a one-for-one basis. Such plan
of arrangement will be subject to court approval following a hearing by
the court on its fairness to TMX Group shareholders. As at least
two-thirds of the outstanding TMX Group shares will be acquired by
Maple at the expiry of the deposit extension period, the applicable
shareholder approvals for the subsequent arrangement are assured. A
management information circular in respect of the subsequent
arrangement is expected to be filed and mailed to TMX Group
shareholders shortly following the expiry of the deposit extension
period, and the shareholder meeting to consider the subsequent
arrangement is scheduled to be held on September 12, 2012.

Maple has received conditional approval to list the Maple shares on
Toronto Stock Exchange following completion of the subsequent
arrangement. Listing of the Maple shares on Toronto Stock Exchange is
subject to the satisfaction of the applicable conditions on or before
October 2, 2012.
