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.

This Policy was approved and adopted by the Board on February 11, 2015 (the "Effective Date") and is effective from and after such date. Notwithstanding this, if this Policy is not approved by ordinary resolution of shareholders of the Company present in person or voting by proxy at the AGSM, then this Policy shall terminate and be of no further force and effect. If this Policy is approved at the AGSM, the Company will formally amend its articles to include the terms and conditions of the Policy.

Primero has filed the full text of the Policy on SEDAR (www.sedar.com) and Edgar (www.sec.gov).

Executive Compensation Advisory Vote "Say On Pay"

In line with governance trends in respect of executive compensation, commonly known as "Say on Pay", the Board has determined to provide shareholders with a "Say on Pay" advisory vote at its AGSM to endorse or not endorse the Company's approach to executive compensation. 

The Board believes that the Company's compensation program must be competitive with companies in its peer group, provide a strong incentive to its officers to achieve the Company's goals and align the interests of management with the interests of the Company's shareholders.

At the AGSM, the shareholders will be asked to consider the following non-binding advisory resolution:

"BE IT RESOLVED, on an advisory basis and not to diminish the role and responsibilities of the Board of Directors, that the shareholders accept the approach to executive compensation disclosed in the Company's Circular delivered in advance of the 2015 annual general and special meeting of Shareholders."

Since this vote is advisory, it will not be binding on the Board. The Board remains fully responsible for its compensation decisions and is not relieved of this responsibility. However, the Board and the Human Resources Committee will consider the outcome of the vote, as appropriate, when considering future compensation policies, procedures and decisions, all of which are to be consistent with its pay for performance compensation model (see "Statement of Executive Compensation" in the Company's 2015 Management Information Circular filed on SEDAR (www.sedar.com) and Edgar (www.sec.gov) for details regarding the compensation philosophy and guidelines of the Board).
