The purpose of the Corporation is to conduct any lawful business, to promote any lawful purpose and to engage in any lawful act or activity for which a corporation may be organized under the General Corporation Law of the State of Delaware. The Corporation is to have perpetual existence.

4.1Authorized Capital Stock. The Corporation is authorized to issue two classes of stock to be designated, respectively, “Common Stock” and “Preferred Stock.” The total number of shares which the Corporation is authorized to issue is One Billion One Million (1,001,000,000) shares. One Billion (1,000,000,000) shares shall be Common Stock, each having a par value of one-tenth of one cent ($.001), and One Million (1,000,000) shares shall be Preferred Stock, each having a par value of one-tenth of one cent ($.001).

4.2Preferred Stock. The Preferred Stock may be issued from time to time in one or more series. The Board of Directors is hereby authorized, by filing a certificate (a “Preferred Stock Designation”) pursuant to the Delaware General Corporation Law, to fix or alter from time to time the designation, powers, preferences and rights of the shares of each such series and the

qualifications, limitations or restrictions of any wholly unissued series of Preferred Stock, and to establish from time to time the number of shares constituting any such series or any of them; and to increase or decrease the number of shares subsequent to the issuance of shares of that series, but not below the number of shares of such series then outstanding. In case the number of shares of any series shall be decreased in accordance with the foregoing sentence, the shares constituting such decrease shall resume the status that they had prior to the adoption of the resolution originally fixing the number of shares of such series.

5.1Election of Directors. Elections of directors need not be by written ballot unless the Bylaws of the Corporation shall so provide. At each annual meeting of stockholders, directors of the Corporation shall be elected to hold office until the expiration of the term for which they are elected, and until their successors have been duly elected and qualified; except that if any such election shall not be so held, such election shall take place at a stockholders’ meeting called and held in accordance with the Delaware General Corporation Law. Commencing with the 2013 annual meeting of stockholders, directors shall be elected at each annual meeting of stockholders to hold office until the next annual meeting and until their respective successors have been duly elected and qualified. Directors elected at the 2010 annual meeting of stockholders shall hold office until the 2013 annual meeting of stockholders, directors elected at the 2011 annual meeting of stockholders shall hold office until the 2014 annual meeting of stockholders, and directors elected at the 2012 annual meeting of stockholders shall hold office until the 2015 annual meeting of stockholders.

5.2Number of Directors. The number of directors of the Corporation shall be fixed from time to time by a bylaw or amendment thereof duly adopted by the Board of Directors or by the stockholders. Vacancies occurring on the board of directors for any reason may be filled by vote of a majority of the remaining members of the board of directors, although less than a quorum, at any meeting of the board of directors. A person so elected by the board of directors to fill a vacancy shall hold office until the unexpired portion of the term of the director whose place shall be vacant, and until his or her successor shall have been duly elected and qualified.

5.3Additional Authority. Except as otherwise provided in this Restated Certificate of Incorporation, in furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized to make, repeal, alter, amend and rescind any or all of the Bylaws of the Corporation.

Stockholders of the Corporation shall take action by meetings held pursuant to this Restated Certificate of Incorporation and the Bylaws. Stockholders of the Corporation shall have no right to take any action by written consent without a meeting. Subject to the rights of the holders of any stock having a preference over the Common Stock as to the dividends or liquidation, special meetings of the stockholders shall be called only by the Board, the Chairman of the Board or the Chief Executive Officer. Stockholders shall not be permitted to call a special meeting or to require the Board to call a special meeting of stockholders. Meetings of stockholders may be held within or out of the State of Delaware, as the Bylaws 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 Bylaws of the Corporation.

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 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 Delaware Code 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 Delaware Code order a meeting of the creditors or class of creditors, and/or 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.

8.1Limitation of Directors’ Liability. To the fullest extent permitted by the General Corporation Law of the State of Delaware as the same exists or may hereafter be amended, no director or officer of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer. Without limiting the effect of the preceding sentence, if the General Corporation Law of the State of Delaware is hereafter amended to authorize further reductions in or elimination of the liability of the Corporation’s directors or officers for breach of fiduciary duty, then a director or an officer of the Corporation shall not be liable for any such breach to the fullest extent permitted by the General Corporation Law of the State of Delaware as so amended.

8.2Indemnification of Corporate Agents. To the fullest extent permitted by applicable law, the Corporation is also authorized to provide indemnification of (and advancement of expenses to) such agents (and any other persons to which Delaware law permits this Corporation to provide indemnification) through Bylaw provisions, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise, in excess of the indemnification and advancement otherwise permitted by Section 145 of the General Corporation Law of the State of Delaware law, subject only to limits created by applicable Delaware law (statutory or non-statutory), with respect to actions for breach of duty to the Corporation, its stockholders, and others.

8.3Repeal or Modification. Any repeal or modification of the foregoing provisions of this Article 8 shall not adversely affect any right of indemnification or limitation of liability of an agent of the Corporation relating to the acts or omissions occurring prior to such repeal or modification.

The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Restated 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.

IN WITNESS WHEREOF, this Restated Certificate of Incorporation has been executed by a duly authorized officer of the Corporation on this 13th day of November, 2025.
