The Board of Directors of the Registrant has adopted a new By-Law No. A4 of the Registrant setting out advance notice requirements for director nominations (the “ Advance Notice By-Law ”). At the upcoming 2014 annual general meeting (the “ Meeting ”), shareholders will be asked to consider and, if thought appropriate, pass an ordinary resolution confirming the Advance Notice By-Law.

The Advance Notice By-Law sets forth a procedure requiring advance notice to the Registrant by any shareholder who intends to nominate any person for election as director of the Registrant other than pursuant to (a) a requisition of a meeting made pursuant to the provisions of the Business Corporations Act (Ontario) (the “ OBCA” ), or (b) a shareholder proposal made pursuant to the provisions of the OBCA. Among other things, the Advance Notice By-Law fixes a deadline by which shareholders must notify the Registrant of their intention to nominate directors and sets out the information that shareholders must provide in the notice for it to be valid. In particular, under the Advance Notice By-Law, a shareholder wishing to nominate a director would be required to provide notice to the Registrant in the prescribed form within the following time periods:

In the case of an annual meeting of shareholders (which includes an annual and special meeting held at the same time), not less than 30 nor more than 65 days prior to the date of the annual meeting of shareholders; provided, however, that in the event that the annual meeting of shareholders is to be held on a date that is less than 50 days after the date on which the first public announcement of the date of the annual meeting was made, not later than the close of business on the tenth day following the day on which the first public announcement of the date of the shareholder meeting was made by the Registrant; and

In the case of a special meeting (which is not also an annual meeting) of shareholders called for the purpose of electing directors (whether or not called for other purposes as well), not later than the close of business on the fifteenth day following the day on which the first public announcement of the date of the special meeting of shareholders was made by the Registrant.

If confirmed, the Advance Notice By-Law will provide a mechanism through which shareholders are able to receive appropriate disclosure with respect to proposed director nominees prior to a meeting. It will also provide the Registrant with the opportunity, prior to a meeting, to confirm the eligibility of a proposed director to serve as an independent director and to confirm certain other information about the proposed nominee and the nominating shareholder that could be material to a reasonable shareholder’s understanding of such proposed nominee’s independence, or lack thereof.

The inclusion of advance notice requirements in a corporation’s by-laws has become a common and important tool for public companies in Canada and the United States to ensure that shareholders are provided with appropriate and timely information in connection with the election of directors. The proposed timing for the delivery of a notice under the Advance Notice By-Law and the information that must be submitted are in keeping with recognized good governance principles. The Board believes that the Advance Notice By-Law will benefit shareholders by:

facilitating orderly nomination and meeting processes;

treating all shareholders fairly by providing timely and adequate notice of director nominations; and

allowing all shareholders to fully participate in the director election process and to register an informed vote.

The Advance Notice By-Law has been effective since its adoption by the Board. Pursuant to the provisions of the OBCA, the Advance Notice By-Law will cease to be effective unless confirmed by a resolution of a simple majority of the votes cast by shareholders at the Meeting.

The above summary is qualified in its entirety by the full text of the Advance Notice By-Law which has been furnished as Document 1 attached to this Report.

In no event shall any adjournment or postponement of an annual or special meeting of shareholders or the announcement thereof commence a new time period for the giving of a Nominating Shareholder’s notice as described above.

4.	To be in proper written form, a Nominating Shareholder’s notice to the secretary of the Corporation must:

set forth, as to each person whom the Nominating Shareholder proposes to nominate for election as a director (each, a “ Proposed Nominee ”):

the name, age, business address and, if applicable, residential address of such person;

ii.

iii.

full particulars regarding (1) any proxy or other Arrangement pursuant to which such person or any of its Representatives has a right to vote or direct the voting of any shares of the Corporation, and (2) any other Arrangement of such person or any of its Representatives relating to the voting of any shares of the Corporation or the nomination of any person(s) to the Board;

iv.

All information to be provided in a timely notice pursuant to Section 4 above shall be provided as of the record date for determining shareholders entitled to vote at the meeting (if such date shall then have been publicly announced) and as of the date of such notice. The Nominating Shareholder shall update such information forthwith if there are any material changes in the information previously disclosed.

For the avoidance of doubt, Section 1 above shall be the exclusive means for any person to bring nominations for election to the Board before any annual or special meeting of shareholders of the Corporation. No person shall be eligible for election as a director of the Corporation unless such person has been nominated in accordance with the provisions of this By-Law No. A4; provided, however, that nothing in this By-Law No. A4 shall be deemed to preclude discussion by a shareholder (as distinct from the nomination of directors) at a meeting of shareholders of any matter in respect of which such shareholder would have been entitled to submit a proposal pursuant to the Act.

8.	Notwithstanding the foregoing, the Board may, in its sole discretion, waive all or any of the requirements in this By-Law No. A4.

Nothing in this By-Law No. A4 shall obligate the Corporation or the Board to include in any proxy statement or other shareholder communication distributed by or on behalf of the Corporation or the Board any information with respect to any proposed nomination or any Nominating Shareholder or Proposed Nominee.

10.	For purposes of this By-Law No. A4:
