TMX Group Inc. Files Preliminary Base Shelf Prospectus

Date 26/05/2010

TMX Group Inc. has filed a preliminary short form base shelf prospectus with securities regulators in each of the provinces of Canada. This will enable TMX Group to offer and issue up to $1,000,000,000 of debt, equity or other securities from time to time during the 25-month period after the shelf prospectus becomes final. The preliminary shelf prospectus will not become final until a final shelf prospectus is filed with the provincial securities regulators in Canada and a receipt is obtained. Should TMX Group offer any securities, it will make available a prospectus supplement that will include the specific terms of the securities being offered.

The net proceeds of any such offerings will be used by TMX Group for general corporate purposes, including repaying outstanding indebtedness from time to time, and funding future acquisitions or investments. TMX Group has no immediate intention to raise funds, other than potentially replacing, in whole or in part, its existing three year term credit facility.
