has the status of bankrupt. A director need not hold shares issued by the Corporation. If the Corporation is an offering corporation then at least one-third of the directors shall not be officers or employees of the Corporation or any of its affiliates.

4.3 Number of Directors

The board shall consist of such number of directors as shall be set out in the articles or as may from time to time be determined in accordance with the Act. If the board is empowered by special resolution to determine the number of directors within a range set out in the articles:

4.8 Vacancies

Subject to the Act, a quorum of directors (whether or not the majority of such quorum are resident Canadians) may fill a vacancy among the directors, except a vacancy resulting from:

(a) an increase in the number of directors otherwise than pursuant to a special resolution empowering the board to fix the number of directors within a range set out in the articles;

If the Corporation has fewer than three directors, one of the directors present at a meeting of directors shall be a resident Canadian. Subject to the Act, the board may transact business at a meeting of directors where a majority of resident Canadian directors is not present if a resident Canadian director who is unable to be present approves in writing or by telephone or other communications facilities the business transacted at the meeting, and a majority of resident Canadian directors would have been present had that director been present at the meeting. If the Corporation has only one director, that director may constitute a meeting.
