SEVENTH: (a) This corporation shall to the fullest extent permitted by Delaware law, as in effect from time to time (but, in the case of any amendment of the General Corporation Law of the State of Delaware, only to the extent that such amendment permits this corporation to provide broader indemnification rights than said law permitted this corporation to provide prior to such amendment), indemnify each person who is or was a director or officer of this corporation or of any of its wholly-owned subsidiaries at any time on or after October 28, 1988 who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, or was or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a "proceeding"), by reason of the fact that he or she is or was a director, officer, employee or agent of this corporation or of any of its subsidiaries, or is or was at any time serving, at the request of this corporation, any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise in any capacity against all expense, liability and loss (including, but not limited to, attorneys' fees, judgments, fines, excise taxes or penalties (with respect to any employee benefit plan or otherwise), and amounts paid or to be paid in settlement) incurred or suffered by such director or officer in connection with such proceeding; provided, however, that, except as provided in Paragraph (e) of this Article SEVENTH, this corporation shall not be obligated to indemnify any person under this Article SEVENTH in connection with a proceeding (or part thereof) if such proceeding (or part thereof) was not authorized by the Board of Directors of this corporation and was initiated by such person against (i) this corporation or any of its subsidiaries, (ii) any person who is or was a director, officer, employee or agent of this corporation or any of its subsidiaries and/or (iii) any person or entity which is or was controlled, controlled by, or under common control with, this corporation or has or had business relations with this corporation or any of its subsidiaries. (b) The right to indemnification conferred in this Article SEVENTH shall be a contract right, shall continue as to a person who has ceased to be a director or officer of this corporation or of any of its wholly-owned subsidiaries and shall inure to the benefit of his or her heirs, executors and administrators, and shall include the right to be paid by this corporation the expenses incurred in connection with the defense or investigation of any such proceeding in advance of its final disposition; provided, however, that, if and to the extent that Delaware law so requires, the payment of such expense in advance of the final disposition of a proceeding shall be made only upon delivery to this corporation of an undertaking, by or on 4 behalf of such director or officer or former director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer or former director or officer is not entitled to be indemnified by this corporation. (c) The corporation's obligation to indemnify and to pay expenses in advance of the final disposition of a proceeding under this Article SEVENTH shall arise, and all rights and protections granted to directors and officers under this Article SEVENTH shall vest, at the time of the occurrence of the transaction or event to which any proceeding relates, or at the time that the action or conduct to which any proceeding relates was first taken or engaged in (or omitted to be taken or engaged in), regardless of when any proceeding is first threatened, commenced or completed. (d) Notwithstanding any other provision of this Restated Certificate of Incorporation or the By-Laws of this corporation, no action by this corporation, either by amendment to or repeal of this Article SEVENTH or the By-Laws of this corporation or otherwise shall diminish or adversely affect any right or protection granted under this Article SEVENTH to any director or right or protection granted under this Article SEVENTH to any director or officer or former director or officer of this corporation or of any of its wholly-owned subsidiaries which shall have become vested as aforesaid prior to the date that any such amendment, repeal or other corporate action is taken. (e) If a claim for indemnification and/or for payment of expenses in advance of the final disposition of a proceeding arising under this Article SEVENTH is not paid in full by this corporation within thirty days after a written claim has been received by this corporation, the claimant may at any time thereafter bring suit against this corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. (f) The right to indemnification and the payment of expenses incurred in connection with the defense or investigation of a proceeding in advance of its final disposition conferred in this Article SEVENTH shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of this Restated Certificate of Incorporation, By-laws, agreement, vote of stockholders or disinterested directors or otherwise. This corporation may also indemnify all other persons to the fullest extent permitted by Delaware law. EIGHTH: A. The business and affairs of the corporation shall be managed by or under the direction of the Board of Directors. The number of directors of the corporation shall be fixed by or pursuant to the By-laws of the corporation. Election of directors need not be by written ballot unless the By-laws so provide. B. The term of office of any director shall expire at the next succeeding annual meeting of stockholders. NINTH: A director of this corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except: (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the General Corporation Law of the State of Delaware or (iv) for any transaction from which the director derived any improper personal benefit. If the General Corporation Law of the State of Delaware is amended after approval by the stockholders of this Article NINTH to further eliminate or limit the personal liability of directors, then the liability of a director of the corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law of the State of Delaware, as so amended. No amendment to or repeal of this Article NINTH shall adversely affect any right or protection of a director of the corporation existing at the time of such amendment or repeal.
