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 5:00 p.m.
(Eastern Time) on Tuesday, July 31, 2012, unless further extended or
withdrawn. The TMX Group Board of Directors continues to unanimously
recommend that shareholders accept and tender their shares under 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 that 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 transaction 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 Group shares pursuant to the Maple transaction should make
the Full Deposit Election. Shareholders that would like to support the
Maple transaction but would like to receive as many Maple Shares as
possible for their TMX Group shares pursuant to the Maple transaction
should make the Minimum Deposit Election.

Time to Act

TMX Group shareholders are encouraged to immediately deposit their
shares to the Maple offer:

Beneficial shareholders – If your TMX Group shares are held in a brokerage account or otherwise
through an intermediary, you must contact your broker/intermediary
immediately and advise them of your instructions for depositing your
TMX Shares on your behalf to Maple’s offer prior to 5:00 p.m. (Eastern
time) on July 31, 2012.

Registered Shareholders (who have a physical certificate in their name) – If your TMX Group
shares are held in your own name, please complete the Letter of
Transmittal (printed on GREEN paper) and deposit it along with your
share certificate in the enclosed envelope to the Depositary –
Computershare Investor Services Inc. – along with all other documents
required by the instructions set out in the Letter of Transmittal prior
