Moreover, Claim shall include, but is not limited to, any threatened, pending or contemplated action, suit or proceeding, or any inquiry or investigation, in any way arising out of or alleging any act, error or omission by the Indemnitee as a controlling person of, or as part of a controlling group with respect to, the Corporation or any of its subsidiaries, under any statute, regulation, doctrine, theory, or principle in which liability may be conferred upon a controlling person or group, a person or group exercising control, or any similar status, provided, however, that such control or controlling status derives from or relates to the fact that Indemnitee is or was a director or officer of Corporation or any of its subsidiaries, or is or was serving at the request of Corporation or any of its subsidiaries as a director, officer, employee, trustee, agent or fiduciary of another corporation, partnership, joint venture, employee benefit plan, political action committee, trust or other enterprise, or by reason of anything done or not done by Indemnitee in any such capacity.
