Sheldon S. Adler	Skadden, Arps, Slate, Meagher & Flom 919 Third Avenue New York, New York 10022

SIXTH: I. The business and affairs of the Corporation shall be managed by or under the direction of a Board of Directors consisting of not less than three directors, the exact number of directors to be determined from time to time by resolution adopted by the affirmative vote of a majority of the entire Board of Directors. The directors shall be divided into three classes, designated Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire Board of Directors. Class I directors initially shall be elected for a one-year term to expire at the 1987 annual meeting of stockholders, Class II directors for a two-year term to expire at 1988 annual meeting of stockholders and Class III directors for a three-year term to expire at the 1989 meeting of stockholders. At each succeeding annual meeting of stockholders, beginning in 1987, successors to the class of directors whose term expires at that annual meeting shall be elected for a three-year term. If the number of directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional director of any class elected to fill a vacancy resulting from an increase in such class shall hold office for a term that shall coincide with the remaining term of that class, but in no case will a decrease in the number of directors shorten the term of any incumbent director. A director shall hold office until the annual meeting for the year in which his term expires and until his successor shall be elected and shall qualify, subject however, to prior death, resignation, retirement, disqualification or removal from office. Any vacancy on the Board of Directors that results from an increase in the number of directors may be filled by a majority of the directors then in office, although less than a quorum, or by a sole remaining director. Any director elected to fill a vacancy not

resulting from an increase in the number of directors shall have the same remaining term as that of his predecessor.

Notwithstanding the foregoing, whenever the holders of any one or more classes or series of Preferred Stock issued by the Corporation shall have the right, voting separately by class or series, to elect directors at an annual or special meeting of stockholders, the election, term of office, filling of vacancies and other features of such directorships shall be governed by the terms of this Certificate of Incorporation applicable thereto, and such directors so elected shall not be divided into classes pursuant to this Article SIXTH unless expressly provided by such terms.

II. Except to the extent prohibited by law, the Board of Directors shall have the right (which, to the extent exercised, shall be exclusive) to establish the rights, powers, duties, rules and procedures that from time to time shall govern the Board of Directors and each of its members, including without limitation the vote required for any action by the Board of Directors, and that from time to time shall affect the directors power to manage the business and affairs of the Corporation; and no By-laws shall be adopted by stockholders which shall impair or impede the implementation of the foregoing.

SEVENTH: The directors shall have concurrent power with the stockholders to make, alter, amend, change, add to or repeal the By-Laws of the Corporation. In addition to the powers and authority hereinbefore or by statute expressly conferred upon them, the directors are hereby empowered to exercise all such powers and do all such acts and things as may be exercised or done by the Corporation, subject, nevertheless, to the provisions of the statutes of Delaware, this Certificate of Incorporation, and any By-Laws adopted by the stockholders; provided, however, that no By-Laws hereafter adopted by the stockholders shall invalidate any prior act of the directors which would have been valid if such By-Laws had not been adopted.

EIGHTH: Meetings of stockholders may be held within or without the State of Delaware, as the By-Laws may provide. The books of the Corporation may be kept (subject to any provision contained in the statutes) outside the State of Delaware at such place or places as may be designated from time to time by the Board of Directors or in the By-Laws of the Corporation.

NINTH: Whenever a compromise or arrangement is proposed between the Corporation and its creditors or any class of them and/or between the Corporation and its stockholders or any class of them, any court of the equitable jurisdiction within the State of Delaware may, on the application in a summary way of the Corporation or of any creditor or stockholder thereof or on the application of any receiver or receivers appointed for the Corporation under the provisions of Section 291 of Title 8 of the GCL or on the application of trustees in dissolution or of any receiver or receivers appointed for the Corporation under the provisions of Section 279 of Title 8 of the GCL, order a meeting of the stockholders or class of stockholders of the Corporation, as the case may be, to be summoned in such manner as the said court directs. If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, agree to any

compromise or arrangement and to any reorganization of the Corporation as a consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of the Corporation, as the case may be, and also on the Corporation.

TENTH: The Corporation shall indemnify to the full extent authorized or permitted by law any person made, or threatened to be made, a party to any action or proceeding (whether civil or criminal or otherwise) by reason of the fact that he, his testator or intestate, is or was a director or officer of the Corporation or by reason of the fact that such director or officer, at the request of the Corporation, is or was serving any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, in any capacity. Nothing contained herein shall affect any rights to indemnification to which employees other than directors and officers may be entitled by law. No director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty by such a director as a director. Notwithstanding the foregoing sentence, a director shall be liable to the extent provided by applicable law (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) pursuant to Section 174 of the GCL, or (iv) for any transaction from which such director derived an improper personal benefit. No amendment to or repeal of this Article TENTH shall apply to or have any effect on the liability or alleged liability of any director of the Corporation for or with respect to any acts or omissions of such director occurring prior to such amendment.

ELEVENTH: The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, and all rights conferred upon stockholders herein are granted subject to this reservation.

I, THE UNDERSIGNED, being the incorporator hereinbefore named, for the purpose of forming a corporation pursuant to the GCL, do make this Certificate, hereby declaring and certifying that this is my act and deed and the facts herein stated are true, and accordingly have hereunto set my hand this third day of October, 1986.
