HRS §414-352
How to tell a corporation you want payment for your shares
If a company plans a major action and you disagree, you must tell the company in writing before the vote that you intend to demand payment for your shares. You also must not vote in favor of the action. If you don't follow these steps, you lose the right to payment.
The statute, as written — Notice of intent to demand payment
(a) If proposed corporate action creating dissenters' rights under section 414-342 is submitted to a vote at a shareholders' meeting, a shareholder who wishes to assert dissenters' rights: (1) Must deliver to the corporation before the vote is taken written notice of the shareholder's intent to demand payment for the shareholder's shares if the proposed action is effectuated; and (2) Must not vote the shareholder's shares in favor of the proposed action. (b) A shareholder who does not satisfy the requirements of subsection (a) is not entitled to payment for the shareholder's shares under this part.
