The right of any director or officer (but not employee) to be indemnified or to the reimbursement or advancement of expenses pursuant hereto (i) is a contract right based upon good and valuable consideration, pursuant to which the person entitled thereto may bring suit as if the provisions hereof were set forth in a separate written contract between the Corporation and the director or officer, and (ii) shall continue to exist after the rescission or restrictive modification hereof with respect to events occurring prior thereto. 20-D. The right to be indemnified or to the reimbursement or advancement of expenses pursuant hereto shall in no way be exclusive of any other rights of indemnification or advancement to which any such director, officer or employee may be entitled, under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise both as to action in his official capacity and as to action in another capacity while holding such office, and shall 6 continue as to a person who has ceased to be a director, officer or employee and shall inure to the benefit of the heirs, executors and administrators of such person. 20-E.
