THIRD: The purpose of the Corporation is to engage in any lawful act or activity for which corporations may now or hereafter be
organized under the General Corporation Law of the State of Delaware. 
 FOURTH: 1. The total number of shares of stock
which the Corporation shall have authority to issue is Eight Hundred Ten Million (810,000,000), consisting of Eight Hundred Million (800,000,000) shares of Common Stock, par value One Dollar ($1.00) per share (the “Common Stock”), and

 2. Shares of Preferred Stock may be issued from time to time in one or more classes or series, each of which class or series shall have such distinctive designation or title as shall be fixed by
resolution of the Board of Directors of the Corporation (the “Board of Directors”) prior to the issuance of any shares thereof. Each such class or series of Preferred Stock shall have such voting powers, full or limited, or no voting
powers, and such preferences and relative, participating, optional or other special rights and such qualifications, limitations or restrictions thereof, as shall be stated in such resolution providing for the issuance of such class or series of
Preferred Stock as may be adopted from time to time by the Board of Directors prior to the issuance of any shares thereof pursuant to the authority hereby expressly vested in it, all in accordance with the laws of the State of Delaware. The Board of
Directors is further authorized to increase or decrease (but not below the number of shares of such class or series then outstanding) the number of shares of any class or series subsequent to the issuance of shares of that class or series.

 FIFTH: In furtherance and not in limitation of the powers conferred by statute and subject to Article Sixth hereof,
the Board of Directors is expressly authorized to adopt, repeal, rescind, alter or amend in any respect the bylaws of the Corporation (the “Bylaws”). 







 SIXTH: Notwithstanding Article Fifth hereof, the Bylaws may be adopted, repealed,
rescinded, altered or amended in any respect by the stockholders of the Corporation, but only by the affirmative vote of the holders of not less than a majority of the voting power of all outstanding shares of capital stock entitled to vote thereon,
voting as a single class, and by the holders of any one or more classes or series of capital stock entitled to vote thereon as a separate class pursuant to one or more resolutions adopted by the Board of Directors in accordance with Section 2
of Article Fourth hereof. 
 SEVENTH: The business and affairs of the Corporation shall be managed by and under the
direction of the Board of Directors. Except as may otherwise be provided pursuant to Section 2 of Article Fourth hereof in connection with rights to elect additional directors under specified circumstances which may be granted to the holders of
any class or series of Preferred Stock, the exact number of directors of the Corporation shall be fixed from time to time by the Board of Directors. 
 EIGHTH: All directors of the Corporation shall be of one class and shall serve for a term ending at the annual meeting following the annual meeting at which the director was elected.
Notwithstanding the foregoing sentence of this Article Eighth: each director shall serve until his or her successor is elected and qualified or until his or her death, resignation or removal; no decrease in the authorized number of directors shall
shorten the term of any incumbent director; and additional directors, elected pursuant to Section 2 of Article Fourth hereof in connection with rights to elect such additional directors under specified circumstances which may be granted to the
holders of any class or series of Preferred Stock, shall serve for such term or terms and pursuant to such other provisions as are specified in the resolution of the Board of Directors establishing such class or series. 

NINTH: Except as may otherwise be provided pursuant to Section 2 of Article Fourth hereof in connection with rights to elect
additional directors under specified circumstances which may be granted to the holders of any class or series of Preferred Stock, newly created directorships resulting from any increase in the number of directors, or any vacancies on the Board of
Directors resulting from death, resignation, removal or other causes, shall be filled solely by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Board of Directors. Any director
elected in accordance with the preceding sentence shall hold office for a term that shall end at the first annual meeting following his or her election and shall remain in office until such director’s successor shall have been elected and
qualified or until such director’s death, resignation or removal, whichever first occurs. 
 TENTH: RESERVED.

 ELEVENTH: Any action required or permitted to be taken by the stockholders of the Corporation must be effected at
a duly called annual meeting or at a special meeting of stockholders of the Corporation, unless the Board of Directors authorizes such action to be taken by the written consent of the holders of outstanding shares of capital stock having not less
than the minimum voting power that would be necessary to authorize or take such action at a meeting of stockholders at which all shares 







 
entitled to vote thereon were present and voted, provided all other requirements of applicable law and this Restated Certificate of Incorporation have been satisfied. 

TWELFTH: Subject to the terms of any class or series of Preferred Stock, special meetings of the stockholders of the Corporation
may be called by the Board of Directors (or an authorized committee thereof) or the Chairperson of the Board of Directors and shall be called by the Secretary of the Corporation following the Secretary’s receipt of written requests to call a
meeting from the holders of at least 25% of the voting power of the outstanding capital stock of the Corporation who have delivered such requests in accordance with and subject to the provisions of the Bylaws (as amended from time to time),
including any limitations set forth in the Bylaws on the ability to make such a request for such a special meeting. Except as otherwise required by law or provided by the terms of any class or series of Preferred Stock, special meetings of
stockholders of the Corporation may not be called by any other person or persons. 
 THIRTEENTH: Meetings of stockholders
of the Corporation may be held within or without the State of Delaware, as the Bylaws may provide. The books of the Corporation may be kept (subject to any provision of applicable law) 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 Bylaws. 
 FOURTEENTH: The Corporation reserves the
right to adopt, repeal, rescind, alter or amend in any respect any provision contained in this Restated Certificate of Incorporation in the manner now or hereafter prescribed by applicable law, and all rights conferred on stockholders herein are
granted subject to this reservation. 
 FIFTEENTH: A director of the Corporation shall not be personally liable to the
Corporation or to its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to the Corporation or to 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
derives any improper personal benefit. If, after approval of this Article by the stockholders of the Corporation, the General Corporation Law of the State of Delaware is amended to authorize the further elimination or limitation of the 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. 

Any repeal or modification of this Article by the stockholders of the Corporation shall not adversely affect any right or protection of a
director of the Corporation existing at the time of such repeal or modification.
