Except as provided in the next sentence, the waiver must be in writing, signed by the Director entitled to the notice, and filed with the minutes or corporate records.

Meeting by Telephone, etc. Any or all of the members of the Board or of any committee designated by the Board may participate in a meeting of the Board or the committee by means of conference telephone or similar communications equipment by which all Directors participating may simultaneously hear each other during the meeting, and participation by these means constitutes presence in person at the meeting.

Section 4.10. Removal. Any Director may be removed, either with or without cause, at any meeting of the Shareholders called for that purpose if the meeting notice states that the purpose or one of the purposes of the meeting is removal of the Director and if the number of votes cast to remove the Director exceeds the number of votes cast not to remove the Director. If the notice so provides, the vacancy caused by the removal may be filled at the meeting by vote of the holders of a majority of the outstanding shares present and entitled to vote for the election of Directors. Section 4.11. Vacancies. Any vacancy occurring in the Board, caused by removal, resignation, death or other incapacity, or increase in the number of Directors, may be filled by the Shareholders or by the Board, or, if the Directors remaining in office constitute fewer than a quorum of the Board, they may fill the vacancy by a majority vote of the remaining members of the Board, until the next annual meeting of the Shareholders, or until the earlier removal, resignation, death or other incapacity of the Director.
