Ind. Code § 23-1-37-2
As used in this chapter, "director" means an individual who is or was a director of a corporation or an individual who, while a director of a corporation, is or was serving at the corporation's request as a director, officer, partner, member, manager, trustee, employee, or agent of another foreign or domestic corporation, partnership, limited liability company, joint venture, trust, employee benefit plan, or other enterprise, whether for profit or not. A director is considered to be serving an employee benefit plan at the corporation's request if the director's duties to the corporation also impose duties on, or otherwise involve services by, the director to the plan or to participants in or beneficiaries of the plan. "Director" includes, unless the context requires otherwise, the estate or personal representative of a director.
