Capitalized terms not otherwise defined in this Form of Proxy have the meaning ascribed to them in the management proxy circular (the “Circular”) dated January 10, 2008 which accompanies this Form of Proxy. In the event of any contradiction between this Form of Proxy and the Circular, the Circular shall govern.

Without limiting the general powers hereby conferred, the undersigned hereby directs the said proxyholder to vote the shares represented by this instrument of proxy in the following manner:

1.  FOR o or AGAINST o (or if no choice is specified, FOR) the approval of the Amalgamation Resolution relating to the Amalgamation of MX with an indirect wholly-owned subsidiary of TSX Group Inc., as specifically set forth in Appendix “A” to the Circular; and

2.  At the discretion of the said proxyholders, upon any amendment or variation of the above matters or any other matter that may properly come before the Meeting or any adjournment or postponement thereof in such manner as such proxyholder, in such proxyholder’s sole judgment, may determine.

This Form of Proxy is solicited on behalf of the management of MX. The shares represented by this Form of Proxy will be voted, where the shareholder has specified a choice with respect to the above matters, as directed above or, if no direction is given, will be voted FOR the Amalgamation Resolution.

Each shareholder has the right to appoint a proxyholder, other than the persons designated above, who need not be a shareholder of MX, to attend, act and vote for him and on his behalf at the Meeting. To exercise such right, the names of the nominees of management should be crossed out and the name of the shareholder’s appointee should be legibly printed in the blank space provided.

The undersigned hereby revokes any proxies heretofore given.

Dated this       day of                      , 2008.
