Members shall be appointed by the Board based on nominations recommended by the Company's Corporate Governance Committee or a sub-committee thereof, and shall serve for such term as the Board may determine.

The Committee shall have a clear understanding with Management and the Auditors that the Auditors are accountable to the Board and the Committee, as representatives of the Company's Shareholders.
