duty as a director, except (i) for any breach of the director’s duty of loyalty to the Corporation or its stockholders, or (ii) for acts or omissions which are not in good faith or which involve intentional misconduct or knowing violation of the law, or (iii) for any matter in respect of which such director shall be liable under Section 174 of Title 8 of the General Corporation Law of the State of Delaware or any amendment thereto or successor provision thereto, or (iv) for any transaction from which the director shall have derived an improper personal benefit. Neither amendment nor repeal of this paragraph (a) nor the adoption of any provision of the Certificate of Incorporation inconsistent with this paragraph (a) shall eliminate or reduce the effect of this paragraph (a) in respect of any matter occurring, or any cause of action, suit or claim that, but for this paragraph (a) of this Article SEVENTH, would accrue or arise, prior to such amendment, repeal or adoption of an inconsistent provision.

(b) The Corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to, or testifies in, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative in nature, by reason of the fact that such person is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, employee benefit plan, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding to the full extent permitted by law, and the Corporation may adopt bylaws or enter into agreements with any such person for the purpose of providing for such indemnification.

Expenses incurred by an officer, director, employee or agent in defending or testifying in a civil, criminal, administrative or investigative action, suit or proceeding may be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such director or officer is not entitled to be indemnified by the Corporation against such expenses as authorized by this Article SEVENTH, and the Corporation may adopt bylaws or enter into agreements with such persons for the purpose of providing for such advances.

The indemnification permitted by this Article SEVENTH shall not be deemed exclusive of any other rights to which any person may be entitled under any agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding an office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such person.

The Corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, employee benefit plan trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Corporation would have the power to indemnify such person against such liability under the provisions of this Article SEVENTH or otherwise.
