# Footnotes

1 unrelated director means a director who is: (a) not a member of management and is free from any interest and any business, family or other relationship which could reasonably be perceived to materially interfere with the directors ability to act with a view to the best interests of the issuer, other than interests and relationships arising solely from holdings in the issuer, (b) not currently, or has not been within the last three years, an officer, employee of or material service provider to the issuer or any of its subsidiaries or affiliates; and (c) not a director (or similarly situated individual) officer, employee or significant shareholder of an entity that has a material business relationship with the issuer.  A chair or vice chair of the board of directors who is not a member of management is not, for that reason alone, a related director.
