Advance Notice Policy

Primero also announces today the approval by its Board of Directors of an Advance Notice Policy (the "Policy"), the purpose of which is to provide shareholders, directors, and management of the Company with a clear framework for nominating directors in certain circumstances. The Policy fixes a deadline by which holders of record of common shares of the Company must submit director nominations to the Company in writing prior to any annual or special meeting of shareholders and sets forth the information that a shareholder must include in the notice for it to be valid.

It is the position of the Board and the Company that this Policy is in the best interest of the Company, its shareholders and other stakeholders. This policy will be subject to an annual review, and will reflect changes as required by applicable securities regulatory agencies or stock exchanges, or so as to meet industry standards.

In the case of an annual meeting of shareholders, notice to the Company must be made not less than 30 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 (the "Notice Date") on which the first public announcement of the date of the annual meeting was made, notice may be made not later than the close of business on the 15^th day following the Notice Date.

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), notice to the Company must be made not later than the close of business on the 15^th day following the day on which the first public announcement of the date of the special meeting of shareholders was made.
