a) make a formal take-over bid for shares of the Issuers referred to above;

b) propose a transaction that would constitute a take-over bid in reliance on an exemption in the Securities Act (Ontario); or

c) propose a reorganization, amalgamation, merger, arrangement or similar business combination with any of the Issuers referred to above which would result in IGIM's managed accounts controlling any of such Issuers, alone or with others.

To the best of its knowledge, IGIM and its managed accounts do not in the ordinary course of business receive material facts or changes about the Issuers referred to above which have not been publicly disclosed.
