The securities registered hereunder also include such indeterminate number of each class of identified securities as may be issued upon conversion, exercise or exchange of any other securities that provide for such conversion into, exercise for or exchange into such securities.

In addition, pursuant to Rule 416 under the United States Securities Act of 1933, as amended, the common shares being registered hereunder include such indeterminate number of common shares as may be issuable with respect to the shares being registered hereunder as a result of stock splits, stock dividends, or similar transactions. The proposed maximum initial offering price per security will be determined, from time to time, by the Registrant in connection with the sale of the securities under this Registration Statement.

(2) The common shares include certain share purchase rights (the “Rights”) issued pursuant to that certain Amended and Restated Shareholder Rights Agreement between the Company and Computershare Investor Services Inc., as rights agent (the “Rights Plan”). Until the occurrence of certain events specified in the Rights Plan, none of which have occurred as of the filing of this Registration Statement, the Rights are not exercisable, are evidenced only by the certificates for common shares, if any, and will be transferred along with and only with, and are not severable from, the common shares. The value attributable to the Rights, if any, is reflected in the market price of the common shares. No separate consideration will be payable for the Right.
