A. PURPOSE

The overall purpose of the Audit Committee (the "Committee") is to ensure that the Company's management has designed and implemented an effective system of internal financial controls, to review and report on the integrity of the consolidated financial statements and related financial disclosure of the Company and to review the Company's compliance with regulatory and statutory requirements as they relate to financial statements, taxation matters and disclosure of financial information.

B. COMPOSITION, PROCEDURES AND ORGANIZATION

The Committee shall consist of at least three members of the Board of Directors (the "Board"), the majority of whom shall not be officers, employees or control persons of the Company or its associates or affiliates (as the terms “control person”, “associate” and “affiliate” are defined in the TSX Venture Exchange’s Corporate Finance Manual).

The Board, at its organizational meeting held in conjunction with each annual general meeting of the shareholders, shall appoint the members of the Committee for the ensuing year. The Board may at any time remove or replace any member of the Committee and may fill any vacancy in the Committee.
Unless the Board has appointed a chair of the Committee, the members of the Committee shall elect a chair and a secretary from among their number.
The quorum for meetings shall be a majority of the members of the Committee, present in person or by telephone or other telecommunication device that permits all persons participating in the meeting to speak and to hear each other.
The Committee shall have access to such officers and employees of the Company and to the Company's external auditors, and to such information respecting the Company, as it considers to be necessary or advisable in order to perform its duties and responsibilities.
Meetings of the Committee shall be conducted as follows:
1. the Committee shall meet at least four times annually, or more frequently as circumstances dictate, at such times and at such locations as may be requested by the chair of the Committee. The external auditors or any member of the Committee may request a meeting of the Committee;
2. the external auditors shall receive notice of and have the right to attend all meetings of the Committee; and
3. management representatives may be invited to attend all meetings except private sessions with the external auditors.
The external auditors shall communicate directly to the Committee through its chair and may bypass management if deemed necessary. The Committee, through its chair, may contact directly any employee in the Company as it deems necessary, and any employee may bring before the Committee any matter involving questionable, illegal or improper financial practices or transactions.
