such Corporator's election. No person shall be elected or re-elected as a
Corporator for a term extending beyond his or her 75th birthday.

            Section 2. MEETINGS. The Annual Meeting of the Corporators shall be

            Section 5. RESIGNATION AND REMOVAL. Any Corporator may resign at any
time by giving written notice to the President or the Clerk. Unless otherwise

Board of Corporators present and voting be declared forfeited, and the Clerk
shall notify him or her of the action taken. If any member of the Board of
Corporators fails to attend three consecutive annual meetings, his or her
membership shall be declared forfeited, and the Board of Corporators shall

cause, including but not limited to a violation of the Corporation's Standards
of Conduct as in effect on the date of such violation, by a two-thirds vote of
the Corporators present and voting or by a two-thirds vote of the Board of
Trustees at a regular or special meeting of the Trustees. In the event any
Corporator is employed by a subsidiary bank of the Corporation as an officer or
other employee and such officer or other employee resigns from such position or
is terminated from such position, with or without cause, then the Board of
Trustees, by a majority vote, may in its discretion remove such person from his

notice of such meeting, except where a Trustee attends a meeting for the express
purpose of objecting to the transaction of any business because such meeting is
not lawfully called or convened.
