Director and Executive Share Ownership Guidelines Directors’ Share Ownership Guidelines Alcan’s Directors’ Share Ownership Guidelines are set out in section VII. 3. of the Alcan Inc. Board of Directors Charter, which reads as follows: In order to ensure alignment of the interests of Directors with those of Shareholders, at least one half of the Directors’ fees are paid to non-executive Directors in Deferred Share Units, being the economic equivalent of the Common Shares of the Company. All non-executive Directors must hold a minimum of the equivalent of three times their respective annual Director’s fees in the form of (i) Common Shares of the Company and/or (ii) Deferred Share Units. Directors will have five years from the time of their first election to the Board to meet these Share ownership requirements.
