A majority of the entire membership may vote to dissolve the credit union at a regular or special meeting called for that expressly stated purpose. Any member, within twenty days of the date of the mailing of notice of such meeting, may vote on the question of dissolution by signing a statement in form approved by the superintendent of credit unions, and such vote shall have the same force and effect as any other vote. The credit union shall thereupon immediately cease to do all business except for the purpose of liquidation, and the president and secretary shall, within fifteen days following such meeting, notify the superintendent in writing of its intention to liquidate, and shall include in such notice a list of the names of directors and officers of the credit union together with their addresses.
