Alpha and the Maple Proposal

Business as Usual and Committed to our Mandate

TORONTO, May 17, 2011 - Alpha Group ("Alpha") commented today that it remains committed to making
the Canadian capital markets more efficient, less expensive, more liquid and
will continue business as usual, as well as execute on all its strategic
initiatives including its application to become a listing exchange.

On May 14, 2011, Alpha was informed of the Maple Group Acquisition
Corporation ("Maple") proposal to acquire the TMX Group and to seek its
merger with the Canadian Depository for Securities ("CDS") and Alpha. Alpha
was not a participant in any discussions with the Maple proponents and has no
further information on the Maple proposal than what has been publicly
disclosed to date.

"We are a driving force in our industry, in the capital formation process
in Canada, and in the overall Canadian economy's global competitive advances,
"stated Jos Schmitt, CEO of Alpha Group. "Alpha is an agent of change that
has brought a competitive marketplace and a new level of maturity to the
Canadian capital markets. That maturity is at the basis of the various
developments that we see today. With the advent of the Maple proposal, we as
an industry are now presented with multiple paths to move forward, and once a
final choice is made there is no doubt in my mind that the journey will
continue to be extremely exciting."

Since 2008, Alpha has been a successful catalyst of change in the
Canadian capital markets industry, gaining over 20% of the combined TSX and
TSX-V listed securities trading volume. Because of Alpha, the Canadian market
is more efficient, trading costs have been reduced significantly, liquidity
has increased and new, innovative technology and services have made our
industry more competitive globally. Alpha will continue to champion these
core principles, regardless of the path that will be chosen by the Canadian
capital markets industry.

"From day one we have sought to redefine our entire industry for the
better," continued Schmitt. "Our commitment to that vision is unwavering.
Discussions on Alpha's corporate future are a shareholder matter. Therefore
Alpha management will remain removed from the discussions and focused on
executing our mandate and strategy."
