Indiana Code Title 27. Insurance § 27-1-9-9

Sec. 9. (a) If any shareholder of any corporation a party to a merger or consolidation who did not vote in favor of such merger or consolidation at the meeting at which the agreement of merger or consolidation was adopted by the shareholders of such corporation shall, at any time within thirty (30) days after the filing of the affidavit of notice of the adoption of the agreement of merger or consolidation as provided for in sections 3 and 4 of this chapter, object thereto in writing and demand payment of the value of his shares, the surviving or new corporation shall, in the event that the merger or consolidation shall be made effective, pay to such shareholder upon surrender of his certificates therefor, the value of such shares at the effective date of the merger or consolidation.  If within thirty (30) days after such effective date, the value of such shares is agreed upon between the shareholder and the surviving or new corporation, as the case may be, payment therefor may be made within ninety (90) days after the effective date.  If, within thirty (30) days after such effective date, the surviving or new corporation, as the case may be, and the shareholder do not so agree, either such corporation or the shareholder may, within ninety (90) days after such effective date, petition the judge of the circuit or superior court of the county in which the principal office of the corporation is located, to appraise the value of such shares, and payment of the appraised value thereof shall be made within sixty (60) days after the entry of the judgment or order finding such appraised value.  The practice, procedure, and judgment in the circuit or superior court upon such petition shall be the same, so far as practicable, as that under the eminent domain laws in this state, and the judgment of such circuit or superior court in such matter shall be final.

(b) Upon the effective date of the merger or consolidation, any shareholder who has made such objection and demand shall cease to be a shareholder and shall have no rights with respect to such shares except the right to receive payment therefor.  Every shareholder who did not vote in favor of such merger or consolidation and who does not object in writing and demand payment of the value of his shares at the time and in the manner provided in this section shall be conclusively presumed to have assented to such merger or consolidation.
