Before a conversion plan takes effect, a converting exchange may amend or withdraw the plan by the affirmative vote of at least two-thirds of the members of its board of directors or, if the exchange does not have a board of directors, by approval of the attorney in fact. The written consent of the commissioner is required for any amendment to a conversion plan adopted after the commissioner has approved the plan under Section 829.106.
