death, resignation or removal from office. Despite the expiration of a
director's term, the director continues to serve until a successor is elected
and qualifies or until there is a decrease in the number of directors. (A
decrease in the number of directors does not shorten an incumbent director's
term except in the case of a director continuing to serve beyond the expiration
of his term.) A director may qualify either by giving notice to the Secretary of
his acceptance of the office of director or by attending a meeting of the Board
of Directors. A director may resign by delivering notice to the Board of
Directors or to any other officer of the Corporation.

      5.2 VACANCIES. If a vacancy occurs on the Board of Directors, including a
vacancy resulting from the resignation, death or removal of a director and a

taken, the affirmative vote of a majority of directors present is the act of the
Board of Directors, except as otherwise provided in Article 9 of the Bylaws with
respect to the amendment or repeal of bylaws.

meeting of the Board of Directors must be preceded by at least two (2) days
notice of the date, time and place of the meeting. The notice need not describe
the purpose(s) of the special meeting unless a purpose is to remove an officer
or director in which case notice of that purpose shall be given. Notice of a
special meeting may be communicated orally. Whether or not the notice of a
special meeting describes the purpose(s) of the meeting, the Board of Directors
may consider and act upon any matter at a special meeting.

      5.7 EMERGENCY MEETINGS. It an extraordinary event prevents a quorum of the
Board of Directors from assembling in time to deal with the business for which a
meeting has been or is to be called, any director may call an emergency meeting
of the Board of directors. Notice of an emergency meeting need be given only to
those directors whom it is practicable to reach and may be given in any
practicable manner allowable under the Law. One (1) or more officers of the
Corporation present at an emergency meeting of the Board of Directors may be
deemed to be directors for the meeting, in order of rank and within the same
rank in order of seniority, as necessary to achieve a quorum.
