Nebraska Revised Statute 21-2,180
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. A shareholder offered payment under section 21-2,179 who is dissatisfied with that offer must reject the offer and demand payment of the shareholder's stated estimate of the fair value of the shares plus interest.
(b) A shareholder who fails to notify the corporation in writing of that shareholder's demand to be paid the shareholder's stated estimate of the fair value plus interest under subsection (a) of this section within thirty days after receiving the corporation's payment or offer of payment under section 21-2,178 or 21-2,179, respectively, waives the right to demand payment under this section and shall be entitled only to the payment made or offered pursuant to those respective sections.
