Terminated Merger Agreement - TMX and LSE Groups

June 30, 2011

The Autorité des marchés financiers (“AMF”) announces the cancellation of its public consultation, including the public hearings that had been scheduled for July 14 and 15, 2011, organized for the purpose of gathering comments on the proposed transaction between TMX Group Inc. (“TMX Group”) and London Stock Exchange Group PLC (“LSEG”).

The cancellation is further to the request for withdrawal submitted on June 29, 2011 by TMX Group, LSEG and Bourse de Montréal Inc. with respect to the application filed on May 13, 2011 seeking authorization for various aspects related to the proposed transaction.

However, the AMF will continue with its examination of the application filed on May 13, 2011 by the Canadian Derivatives Clearing Corporation (“CDCC”) seeking recognition as a clearing house.
