To the fullest extent permitted by the Delaware General Corporation Law, as the same exists or may hereafter be amended (the “Delaware Law”), a director of the corporation shall not be liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. The corporation shall indemnify, in the manner and to the fullest extent permitted by the Delaware Law, any person (or the estate of any person) who is or was a party to, or is threatened to be made a party to, any threatened, pending or completed action, suit or proceeding, whether or not by or in the right of the corporation, and whether civil, criminal, administrative, investigative or otherwise, by reason of the fact that such person is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise. The corporation may indemnify, in the manner and to the fullest extent permitted by the Delaware Law, any person (or the estate of any person) who is or was a party to, or is threatened to be made a party to, any threatened, pending or completed action, suit or

proceeding, whether or not by or in the right of the corporation, and whether civil, criminal, administrative, investigative or otherwise, by reason of the fact that such person is or was an employee or agent of the corporation, or is or was serving at the request of the corporation as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise. Expenses incurred by any such director, officer, employee or agent in defending any such action, suit or proceeding may be advanced by the corporation prior to the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director, officer, employee or agent to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified as authorized by the Delaware Law and this Article VIII. The corporation may, to the fullest extent permitted by the Delaware Law, purchase and maintain insurance on behalf of any such director, officer, employee or agent against any liability which may be asserted against such person.
