All amounts paid on shares of an expelled or withdrawing member, with any dividends accredited thereto to the date thereof, shall, as funds become available and after deducting all amounts due from the member to the credit union, be paid to him. The credit union may require 60 days' notice of intention to withdraw shares. Withdrawing or expelled members shall have no further rights in the credit union, but they shall not by such withdrawal or expulsion be released from any remaining liability to the credit union.
