THIRD: The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware, as from time to time amended.

FOURTH: The total number of shares of stock which the Corporation shall have authority to issue is one thousand (1,000) shares of common stock, par value $0.01 per share.

FIFTH: In furtherance and not in limitation of the powers conferred by law, subject to any limitations contained elsewhere in this certificate of incorporation, bylaws of the Corporation may be adopted, amended or repealed by a majority of the Board of Directors of the Corporation, but any bylaws adopted by the Board of Directors may be amended or repealed by the stockholders entitled to vote thereon. Election of directors need not be by written ballot.

SIXTH: (a) Limitation of Liability. No director of the Corporation shall be personally liable to the Corporation or any of its stockholders for monetary damages for breach of fiduciary duty as a director, except that the foregoing provision shall not eliminate or limit the liability of a director (i) for any breach of such 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 Title 8, Section 174 of the Delaware General Corporation Law or (iv) for any transaction from which such director derived an improper personal benefit. If the Delaware General Corporation Law hereafter is amended to authorize the further elimination or limitation on personal liability of directors, then the liability of a director of the Corporation, in addition to the limitation on personal liability provided herein, shall be limited to the fullest extent permitted by the amended Delaware General Corporation Law.

(b) Indemnification. Any person who was or is made a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including an action by or in the right of the Corporation) (hereinafter a “proceeding”), by reason of the fact that he 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 or of a partnership, joint venture, trust or other enterprise shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement, actually and reasonably incurred by him or her in connection therewith; provided, however, that the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) that was initiated by such person only if such proceeding (or part thereof) was authorized or ratified by the Board of Directors of the Corporation. The right to indemnification conferred in this ARTICLE SIXTH, paragraph (b), shall be a contract right. For purposes of this ARTICLE SIXTH, paragraph (b), reference to “the Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued would have had power and authority to indemnify its directors and officers so that any person who is or was a director or officer of such constituent corporation, or is or was serving at the request of such constituent corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this ARTICLE SIXTH, paragraph (b), with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued.

(c) Payment of Expenses in Advance. Expenses (including attorneys’ fees) incurred by an officer or director in defending an action, suit or proceeding referred to in ARTICLE SIXTH, paragraph (b), above may be paid by the Corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board of Directors in the specific case upon receipt of an undertaking by or on behalf of the director or officer to repay such amount unless it shall ultimately be determined that he or she is entitled to be indemnified by the Corporation as authorized in ARTICLE SIXTH, paragraph (b).

(d) Indemnification Not Exclusive. The indemnification provided under ARTICLE SIXTH, paragraph (b), shall not be deemed exclusive of (i) any other rights to which those seeking indemnification may be entitled under any bylaw, any agreement, any insurance purchased by the Corporation, vote of stockholders or disinterested directors or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office or (ii) the power of the Corporation to indemnify any person who is or was an employee or agent of the Corporation or of another corporation, joint venture, trust or other enterprise that he or she is serving or has served at the request of the Corporation, to the same extent and in the same situations and subject to the same determinations with respect to directors and officers. The indemnification provided by ARTICLE SIXTH, paragraph (b), shall continue as to any person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such person.

(e) Other. Any repeal or modification of this ARTICLE SIXTH by the stockholders of the Corporation shall be prospective only, and shall not adversely affect any limitation on the personal liability of a director of the Corporation or the Indemnification of any officer or director of the Corporation existing at the time of such repeal or modification.
