A. A director may resign at any time by delivering a written notice of resignation to the board of directors or its chairman, or to the secretary of the corporation.
B. A resignation is effective as provided in subdivision A 9 of § 13.1-610 unless the resignation provides for a delayed effectiveness including effectiveness determined upon a future event or events. If a resignation provides for a delayed effectiveness, the board of directors may fill the pending vacancy before the effectiveness of the resignation if the board of directors provides that the successor does not take office until the effectiveness of the resignation. A resignation that is conditioned upon failing to receive a specified vote for election as a director may provide that it is irrevocable.

D. Upon the resignation of a director, the corporation may file an amended annual report with the Commission indicating the resignation of the director and the successor in office, if any.
