(a) If the action giving rise to the right to dissent is to be approved at a meeting of shareholders, the notice of meeting shall inform the shareholders of their right to dissent and the procedure to dissent. Prior to the meeting, the savings bank shall furnish to the shareholders material information with respect to the transaction that will enable a shareholder to objectively vote on the transaction and to determine whether or not to exercise dissenters’ rights. A shareholder may assert dissenters’ rights only if the shareholder delivers to the savings bank, before the vote is taken, a written demand for payment for his shares if the proposed action is consummated and the shareholder does not vote in favor of the proposed action.
     (b) If the action giving rise to the right to dissent is not to be approved at a meeting of shareholders, the notice to shareholders describing the action taken shall inform the shareholders of their right to dissent and the procedure to dissent. Prior to, or concurrently with, the notice the savings bank shall furnish to the shareholders material information with respect to the transaction that will enable a shareholder to objectively determine whether or not to exercise dissenters’ rights. A shareholder may assert dissenters’ rights only if he delivers to the savings bank within 30 days from the date of mailing the notice a written demand for payment for his shares.
     (c) The Secretary may promulgate rules to govern the procedure to be used by savings banks and dissenters in arriving at a value and price for dissenters’ shares, as well as how distribution shall be made. In no case shall the rules be more restrictive than the provisions applicable to ordinary corporations under the Business Corporation Act of 1983.
