For purposes of this subsection (e), "fair value", with respect to a petitioning shareholder's shares, means the proportionate interest of the shareholder in the corporation, without any discount for minority status or, absent extraordinary circumstances, lack of marketability.
The purchase ordered pursuant to this subsection (e) shall be consummated within 20 days after the date the order becomes final unless before that time the corporation files with the court a notice of its intention to dissolve and articles of dissolution are properly filed with the Secretary of State within 50 days after filing the notice with the court.
After the purchase order is entered and before the purchase price is fully paid, any party may petition the court to modify the terms of the purchase and the court may do so if it finds that such changes are equitable.
Unless the purchase order is modified by the court, the selling shareholder shall have no further rights as a shareholder from the date the seller delivers all of his or her shares to the purchaser or such other date specified by the court.
If the court orders shares to be purchased by one or more other shareholders, in allocating the shares to be purchased by the other shareholders, unless equity requires otherwise, the court shall attempt to preserve the existing distribution of voting rights and other designations, preferences, qualifications, limitations, restrictions and special or relative rights among the holders of the class or classes and may direct that holders of a specific class or classes shall not participate in the purchase.
