One billion, four hundred million (1,400,000,000) of such shares shall consist of common shares, par value one dollar ($1.00) per share, and one million (1,000,000) of such shares shall consist of preferred shares, par value one dollar ($1.00) per share. The designations and the powers, preferences and rights, and the qualifications, limitations or restrictions thereof are as follows: A. Each share of common stock shall be equal in all respects to all other shares of such stock, and each share of outstanding common stock is entitled to one vote. B. Each share of preferred stock shall have or not have voting rights as determined by the Board of Directors prior to issuance. Dividends on all outstanding shares of preferred stock must be declared and paid, or set aside for payment, before any dividends can be declared and paid, or set aside for payment, on the shares of common stock with respect to the same dividend period. In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, the holders of the preferred stock shall be entitled, before any assets of the Corporation shall be distributed among or paid over to the holders of the common stock, to an amount per share to be determined before issuance by the Board of Directors, together with a sum of money equivalent to the amount of any dividends declared thereon and remaining unpaid at the date of such liquidation, dissolution or winding up of the Corporation. After the making of such payments to the holders of the preferred stock, the remaining assets of the Corporation shall be distributed among the holders of the common stock alone, according to the number of shares held by each. If, upon such liquidation, dissolution or winding up, the assets of the Corporation distributable as aforesaid among the holders of the preferred stock shall be insufficient to permit the payment to them of said amount, the entire assets shall be distributed ratably among the holders of the preferred stock. The Board of Directors shall have authority to divide the shares of preferred stock into series and fix, from time to time, before issuance, the number of shares to be included in any series and the designation, relative rights, preferences and limitations of all shares of such series. The authority of the Board of Directors with respect to each series shall include the determination of any or all of the following, and the shares of each series may vary from the shares of any other in the following respects: (a) the number of shares constituting such series and the designation thereof to distinguish the shares of such series from the shares of all other series; (b) the rate of dividend, cumulative or noncumulative, and the extent of further participation in dividend distribution, if any; (c) the prices at which issued (at not less than par) and the terms and conditions upon which the shares may be redeemable by the Corporation; (d) sinking fund provisions for the redemption or purchase of shares; (e) the voting rights; and (f) the terms and conditions upon which the shares are convertible into other classes of stock of the Corporation, if such shares are to be convertible. 2

C. No holder of any class of stock issued by this Corporation shall be entitled to pre-emptive rights. FIFTH: The Corporation is to have perpetual existence. SIXTH: The private property of the stockholders shall not be subject to the payment of corporate debts to any extent whatever. SEVENTH: (a) 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 five nor more than twelve directors, the exact number of directors to be determined from time to time by resolution adopted by 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. At the 1988 Annual Meeting of stockholders, Class I directors shall be elected for a one-year term, Class II directors for a two-year term and Class III directors for a three-year term. At each succeeding Annual Meeting of stockholders beginning in 1989, 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 or removal from office. Except as otherwise required by law, any vacancy on the Board of Directors that results from an increase in the number of directors shall be filled only by a majority of the Board of Directors then in office, provided that a quorum is present, and any other vacancy occurring in the Board of Directors shall be filled only by a majority of the directors then in office, even if 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 serve for the remaining term of his predecessor. Notwithstanding the foregoing, whenever the holders of any one or more classes or series of preferred stock or any other class of 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 the Certificate of Designation with respect to such stock, such directors so elected shall not be divided into classes pursuant to this Article SEVENTH, and the number of such directors shall not be counted in determining the maximum number of directors permitted under the foregoing provisions of this Article SEVENTH, in each case unless expressly provided by such terms. (b) Nominations for the election of directors may be made by the Board of Directors or by any stockholder entitled to vote in the election of directors. Any stockholder entitled to vote 3

in the election of directors, however, may nominate one or more persons for election as director only if written notice of such stockholder's intent to make such nomination or nominations has been given either by personal delivery or by United States mail, postage prepaid, to the Secretary of the Corporation not later than (i) with respect to an election to be held at an Annual Meeting of stockholders, 45 days in advance of the date on which the Corporation's proxy statement was released to stockholders in connection with the previous year's Annual Meeting of stockholders and (ii) with respect to an election to be held at a special meeting of stockholders for the election of directors, the close of business on the seventh day following the day on which notice of such meeting is first given to stockholders. Each such notice shall include: (A) the name and address of the stockholder who intends to make the nomination or nominations and of the person or persons to be nominated; (B) a representation that the stockholder is a holder of record of stock of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (C) a description of all arrangements or understandings between such stockholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations is or are to be made by the stockholder; (D) such other information regarding each nominee proposed by such stockholder as would have been required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission if the nominee had been nominated by the Board of Directors; and (E) the written consent of each nominee to serve as a director of the Corporation if elected. The chairman of any meeting of stockholders may refuse to acknowledge the nomination of any person if not made in compliance with the foregoing procedure. (c)Notwithstanding any other provision of this Certificate of Incorporation or the by-laws (and notwithstanding the fact that a lesser percentage may be specified by law, this Certificate of Incorporation or the by-laws), and in addition to any affirmative vote required by law, the affirmative vote of the holders of at least 80% of the voting power of the outstanding capital stock of the Corporation entitled to vote, voting together as a single class, shall be required to amend, adopt in this Certificate of Incorporation or in the by-laws any provision inconsistent with, or repeal this Article SEVENTH. EIGHTH:Any action required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of such holders and may not be effected by any consent in writing by any such holders. Except as otherwise required by law, special meetings of stockholders of the Corporation may be called only by the Chairman of the Board, the President or a majority of the Board of Directors, subject to the rights of holders of any one or more classes or series of preferred stock or any other class of stock issued by the Corporation which shall have the right, voting separately by class or series, to elect directors. Notwithstanding any other provision of this Certificate of Incorporation or the by-laws (and notwithstanding that a lesser percentage may be specified by law, this Certificate of Incorporation or the by-laws), and in addition to any affirmative vote required by law, the affirmative vote of the holders of at least 80% of the voting power of the outstanding capital stock of the Corporation entitled to vote, voting together as a single class, shall be required to amend, adopt in this Certificate of Incorporation or in the by-laws any provision inconsistent with, or repeal this Article EIGHTH. 4

Such committee or committees shall have such name or names as may be stated in the by-laws of the Corporation or as may be determined from time to time by resolution adopted by the Board of Directors. When and as authorized by the affirmative vote of the holders of a majority of the stock issued and outstanding having voting power given at a stockholders' meeting duly called for that purpose, to sell, lease or exchange all of the property and assets of the Corporation, including its good will and its corporate franchises, upon such terms and conditions and for such consideration, which may be in whole or in part shares of stock in, and/or other securities of, any other corporation or corporations, as its Board of Directors shall deem expedient and for the best interests of the Corporation. TENTH: Whenever a compromise or arrangement is proposed between this Corporation and its creditors or any class of them and/or between this Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of this Corporation or of any creditor or stockholder thereof, or on the application of any receiver or receivers appointed for this Corporation under the provisions of Section 279 of Title 8 of the Delaware Code order a meeting of the creditors or class of creditors, and/or of the stockholders or class of stockholders of this Corporation, as the case may be, to be summoned in such manner as the said court directs.

Elections of Directors need not be by ballot unless the by-laws of the Corporation shall so provide. TWELFTH: 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.

If the Delaware General Corporation Law hereafter is amended to authorize the further limitation or elimination of the liability of directors, then the liability of a director of the Corporation, in addition to the limitation on liability provided herein, shall be limited to the fullest extent permitted by the Delaware General Corporation Law, as amended. Any repeal or modification of this Article FOURTEENTH shall not increase the liability of any director of this Corporation for any act or occurrence taking place prior to such repeal or modification, or otherwise adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification. FIFTEENTH: 1. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director, officer or employee of the Corporation, whether the basis of such proceeding is alleged action in an official capacity as a director, officer or employee or in any other capacity while serving as a director, officer, or employee, shall be indemnified and held harmless by the Corporation to the fullest extent permitted 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 such law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including, without limitation, attorneys' fees, judgments, fines and amounts paid in settlement) reasonably incurred or suffered by such person in connection therewith, and such indemnification shall continue as to a person who has ceased to be a director, officer or employee and shall inure to the benefit of such person's heirs, executors and administrators. The Corporation shall indemnify a director, officer or employee in connection with an action, suit or proceeding (other than an action, suit or proceeding to enforce indemnification rights provided for herein or elsewhere) initiated by such director, officer or employee only if such action, suit or proceeding was authorized by the Board of Directors. The right to indemnification conferred in this Paragraph I shall be a contract right and shall include the right to be paid by the Corporation the expenses incurred in defending any action, suit or proceeding in advance of its final disposition; provided, however, that, if the Delaware General Corporation Law requires, the payment of such expenses incurred by a director or officer in such person's capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person) in advance of the final disposition of an action, suit or proceeding shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that such director or officer is not entitled to be indemnified for such expenses under this Article FIFTEENTH or otherwise. 2. The Corporation may, to the extent authorized from time to time by the Board of Directors, provide indemnification and the advancement of expenses, to any agent of the Corporation and to any person (other than directors, officers and employees of the Corporation, 9

who shall be entitled to indemnification under Paragraph 1 above) who is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, to such extent and to such effect as the Board of Directors shall determine to be appropriate and permitted by applicable law, as the same exists or may hereafter be amended. 3. The rights to indemnification and to the advancement of expenses conferred in this Article FIFTEENTH shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the Certificate oflncorporation or by-laws of the Corporation, agreement, vote of stockholders or disinterested directors or otherwise.
