Procedure if shareholder dissatisfied with payment or offer.
(MBCA 13.26) (a) A shareholder paid pursuant to section 21-2,178 who is dissatisfied with the amount of the payment must notify the corporation in writing of that shareholder's estimate of the fair value of the shares and demand payment of that estimate plus interest, less any payment under section 21-2,178.
