Common Shares, Debt Securities, Warrants, Units and Subscription Rights are sometimes referred to collectively herein as the “Securities.” Securities may be issued in an unspecified number (with respect to Common Shares, Warrants, Units and Subscription Rights) or in an unspecified principal amount (with respect to Debt Securities). The Registration Statement provides that the Securities may be offered separately or together, in separate series, in amounts, at prices and on terms to be set forth in one or more prospectus supplements (each a “Prospectus Supplement”) to the prospectus contained in the Registration Statement.
