WHERE TO FIND MORE INFORMATION

We have filed with the SEC, under the Securities Act, a registration statement on
Form F-10 relating to the debt securities. This prospectus, which constitutes a part of the registration statement, does not contain all of the information contained in the registration statement, certain
items of which are contained in the exhibits to the registration statement as permitted by the rules and regulations of the SEC. Statements included or incorporated by reference in this prospectus about the contents of any contract, agreement or
other documents referred to are not necessarily complete, and in each instance, you should refer to the exhibits for a complete description of the matter involved. Under the registration statement, we may, from time to time, sell any combination of
the debt securities described in this prospectus in one or more offerings. Each time we sell debt securities under the registration statement, we will provide a prospectus supplement that will contain specific information about the terms of that
offering. The prospectus supplement may also add, update or change information contained in this prospectus.

Subject to the exemptive
relief in the Decision, we file annual and quarterly financial information and material change reports, business acquisition reports and other material with the securities commission or other similar authority in each of the provinces and
territories of Canada and with the SEC. Under the multijurisdictional disclosure system adopted by the U.S., documents and other information that we file with the SEC may be prepared in accordance with the disclosure requirements of Canada, which
are different from those of the U.S. You may read and download any public document that the Corporation has filed with the securities commission or other similar authority in
