The Notes, with respect to the provisions thereof governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein, constitute a legal, valid and binding obligation of the Bank enforceable in accordance with their terms.

The opinions set forth in paragraphs 2 and 3 above as to the enforceability of the Notes and the Indenture, respectively, are subject to the qualifications that:
