II” by the filing of its original certificate of incorporation with the Secretary of State of the State of Delaware on January 29, 2021. This Amended and Restated Certificate of Incorporation (this “Restated Certificate”), which both restates and further amends the provisions of the corporation’s certificate of incorporation, was duly adopted in accordance with the provisions of Sections 242 and 245 of the General Corporation Law of the State of Delaware. The certificate of incorporation of the corporation is hereby amended and restated to read in its entirety as follows:

The total number of shares of Common Stock authorized to be issued is 3,000,000,000 shares of Common Stock, par value $0.0001 per share, which shall be divided into the following series: one series comprised of 2,500,000,000 shares and denominated Class A Common Stock (“Class A Common Stock”); and one series comprised of 500,000,000 shares and denominated Class B Common Stock (“Class B Common Stock” and together with the Class A Common Stock, the “Common Stock”). The total number of shares of Preferred Stock authorized to be issues is 50,000,000 shares of Preferred Stock, $0.0001 par value per share (the “Preferred Stock”). Upon the effectiveness of the Amended and Restated Certificate of Incorporation first setting forth this sentence (the “Effective Time”) each share of the Class K Common Stock (as defined in the certificate of incorporation of the Corporation in effect immediately prior to the

1.2. The number of authorized shares of Common Stock (including the Class A Common Stock or Class B Common Stock) may be increased or decreased (but not below the number of shares thereof then-outstanding) by the affirmative vote of the holders of a majority of the voting power of all of the then-outstanding shares of the capital stock of the Corporation entitled to vote thereon, irrespective of the provisions of Section 242(b)(2) of the General Corporation Law, and no vote of the holders of the Common Stock voting separately as a class (and/or the Class A Common Stock or Class B Common Stock voting separately as a series) shall be required therefor.

2.1. The Corporation’s Board of Directors (the “Board of Directors”) is authorized, subject to any limitations prescribed by the law of the State of Delaware, by resolution or resolutions adopted from time to time, to provide for the issuance of shares of Preferred Stock in one or more series, and, by filing a certificate of designation pursuant to the applicable law of the State of Delaware (“Certificate of Designation”), to establish from time to time the number of shares to be included in each such series, to fix the designation, powers (including voting powers), preferences and relative, participating, optional or other special rights (and the qualifications, limitations or restrictions thereof) of the shares of each such series and, except where otherwise provided in the applicable Certificate of Designation, to increase (but not above the total number of authorized shares of the Preferred Stock) or decrease (but not below the number of shares of such series then outstanding) the number of shares of any such series. The number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of all the then-outstanding shares of capital stock of the Corporation entitled to vote thereon, irrespective of the provisions of Section 242(b)(2) of the General Corporation Law, and no vote of the holders of the Preferred Stock voting separately as a class shall be required therefor, unless a separate vote of the holders of one or more series is required pursuant to the terms of any Certificate of Designation.

2.2. Except as otherwise expressly provided in this Restated Certificate (including any Certificate of Designation designating any series of Preferred Stock pursuant to the foregoing provisions of this Article IV), (i) any new series of Preferred Stock may be designated, fixed and determined as provided herein by the Board of Directors without approval of the holders of the Class A Common Stock or the Class B Common Stock or the holders of the Preferred Stock, or any series thereof, and (ii) any such new series may have powers, preferences and rights, including, without limitation, voting powers, dividend rights, liquidation rights, redemption rights and conversion rights, senior to, junior to or pari passu with the rights of the Class A Common Stock or Class B Common Stock, any series of the Preferred Stock, or any future class or series of capital stock of the Corporation.

3.1. Equal Status. Except as otherwise provided in this Restated Certificate of Incorporation or required by applicable law, shares of Class A Common Stock and Class B Common Stock shall have the same rights and powers, rank equally (including as to dividends and distributions, and upon any liquidation, dissolution or winding up of the Corporation, but excluding voting and other matters as described in Article IV Section 3.2 below), share ratably and be identical in all respects and as to all matters.

3.2. Voting Rights. Except as otherwise expressly provided by this Restated Certificate of Incorporation or as required by law, the holders of shares of Class A Common Stock and Class B Common Stock shall (i) at all times vote together as a single class and not as separate series or classes on all matters (including the election of directors) submitted to a vote of the stockholders of the Corporation, (ii) be entitled to notice of any stockholders’ meeting in accordance with the Bylaws of the Corporation (as the same may be amended and/or restated from time to time, the “Bylaws”) and (iii) be entitled to vote upon such matters and in such manner as may be provided by applicable law; provided, however, that, except as otherwise required by law or this Restated Certificate of Incorporation, holders of shares of Class A Common Stock and Class B Common Stock shall not be entitled to vote on any amendment to this Restated Certificate of Incorporation (including any Certificate of Designation relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together as a class with the holders of one or more other such series, to vote thereon pursuant to this Restated Certificate of Incorporation (including any Certificate of Designation relating to any series of Preferred Stock). Except as otherwise expressly provided herein or required by applicable law, each holder of Class A Common Stock shall have the right to one (1) vote per share of Class A Common Stock held of record by such holder and each holder of Class B Common Stock shall have the right to ten (10) votes per share of Class B Common Stock held of record by such holder.

3.3. Dividends and Distribution Rights. Shares of Class A Common Stock and Class B Common Stock shall be treated equally, identically and ratably, on a per share basis, with respect to any dividends or distributions as may be declared and paid from time to time by the Board of Directors out of any assets of the Corporation legally available therefor; provided, however, that in the event a dividend is paid in the form of shares of Class A Common Stock or Class B Common Stock (or rights to acquire such shares), then holders of Class A Common Stock shall receive shares of Class A Common Stock (or rights to acquire such shares, as the case may be) and holders of Class B Common Stock shall receive shares of Class B Common Stock (or rights to acquire such shares, as the case may be), with holders of shares of Class A Common Stock and Class B Common Stock receiving, on a per share basis, an identical number of shares of Class A Common Stock or Class B Common Stock, as applicable. Notwithstanding the foregoing, the Board of Directors may pay or make a disparate dividend or distribution per share of Class A Common Stock or Class B Common Stock (whether in the amount of such dividend or distribution payable per share, the form in which such dividend or distribution is payable, the timing of the payment, or otherwise) if (i) such disparate dividend or distribution is approved in advance by the affirmative vote of the holders of a majority of the then-outstanding shares of

Class A Common Stock and Class B Common Stock, each voting separately as a class or (ii) such disparate dividend or distribution is paid in the form of securities (or the right to receive securities) of another entity, and (A) the holders of Class A Common Stock receive securities entitling the holder thereof to cast one vote per security (or the right to receive such securities, as applicable) and (B) the holders of Class B Common Stock receive securities entitling the holder thereof to cast ten (10) votes per security (or the right to receive such securities, as applicable). The terms of any securities distributed to stockholders pursuant to the preceding clause (ii) shall be substantially identical, other than with respect to voting rights.

3.4. Subdivisions, Combinations or Reclassifications. Shares of Class A Common Stock or Class B Common Stock may not be subdivided, combined or reclassified unless the shares of the other class are concurrently therewith proportionately subdivided, combined or reclassified in a manner that maintains the same proportionate equity ownership between the holders of the outstanding Class A Common Stock and Class B Common Stock on the record date for such subdivision, combination or reclassification; provided, however, that shares of one such class may be subdivided, combined or reclassified in a different or disproportionate manner if such subdivision, combination or reclassification is approved in advance by the affirmative vote of the holders of a majority of the then-outstanding shares of Class A Common Stock and Class B Common Stock, each voting separately as a class.

3.5. Liquidation, Dissolution or Winding Up. Subject to the preferential or other rights of any holders of Preferred Stock then outstanding, upon the liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, holders of Class A Common Stock and Class B Common Stock will be entitled to receive ratably, on a per share basis, all assets of the Corporation available for distribution to its stockholders unless disparate or different treatment of the shares of each such class with respect to distributions upon any such liquidation, dissolution or winding up is approved in advance by the affirmative vote of the holders of a majority of the then-outstanding shares of Class A Common Stock and Class B Common Stock, each voting separately as a class; provided, that for the avoidance of doubt, consideration to be paid or received by a holder of Common Stock pursuant to any employment, consulting, severance or similar services arrangement shall not be deemed to be assets of the Corporation available for distribution to its stockholders for the purpose of this Section 3.5.

3.6. Merger or Consolidation. In the case of any distribution or payment made or other consideration paid in respect, or upon conversion or exchange, of the shares of Class A Common Stock or Class B Common Stock upon the merger or consolidation of the Corporation with or into any other entity, or in the case of any other transaction having an effect on stockholders substantially similar to that resulting from a merger or consolidation, such distribution or payment shall be made, or other consideration shall be paid, ratably on a per share basis among the holders of the Class A Common Stock and Class B Common Stock as a single class; provided, however, that shares of one such class may receive different or disproportionate distributions, payments, or other consideration in connection with such merger, consolidation or other transaction if (i) the only difference in the per share distribution, payment, or other consideration to the holders of the Class A Common Stock and Class B Common Stock is that any securities that a holder of a share of Class B Common Stock receives as part of such merger,

consolidation or other transaction upon conversion or in exchange for such holder’s Class B Common Stock shall have ten (10) times the voting power of any securities that a holder of a share of Class A Common Stock receives as part of such merger, consolidation or other transaction upon conversion or in exchange for such holder’s Class A Common Stock, or (ii) such merger, consolidation or other transaction is approved by the affirmative vote of the holders of a majority of the then-outstanding shares of Class A Common Stock and Class B Common Stock, each voting separately as a class; provided, further, that for the avoidance of doubt, consideration to be paid or received by a holder of Common Stock in connection with any such merger, consolidation or other transaction pursuant to any employment, consulting, severance or similar services arrangement shall not be deemed to be consideration paid in respect, or upon conversion or exchange, of shares of Common Stock for the purpose of this Section 3.6.

3.7. Determinations by the Board of Directors. In case of an ambiguity in the application of any provision set forth in this Section 3 or in the meaning of any term or definition set forth in this Section 3, the Board of Directors, but not a committee thereof, shall have the power to determine, in its sole discretion, the application of any such provision or any such term or definition with respect to any situation based on the facts believed in good faith by it. A determination of the Board of Directors in accordance with the preceding sentence shall be conclusive and binding on the stockholders of the Corporation. Such determination shall be evidenced in a writing adopted by the Board of Directors, and such writing shall be made available for inspection by any holder of capital stock of the Corporation at the principal executive offices of the Corporation.

1. Optional Conversion. Each share of Class B Common Stock shall be convertible into one (1) fully paid and nonassessable share of Class A Common Stock at the option of the holder thereof at any time upon written notice to the Corporation. Before any holder of Class B Common Stock shall be entitled to convert any of such holder’s shares of such Class B Common Stock into shares of Class A Common Stock, such holder shall deliver an instruction, duly signed and authenticated in accordance with any procedures set forth in the Bylaws or any policies of the Corporation then in effect (which will be available upon request therefor made to the Secretary), at the principal corporate office of the Corporation or of any transfer agent for the Class B Common Stock, and shall give written notice to the Corporation at its principal corporate office of such holder’s election to convert the same and shall state therein the name or names in which the shares of Class A Common Stock issuable on conversion thereof are to be registered on the books of the Corporation. The Corporation shall, as soon as practicable thereafter, register on the Corporation’s books ownership of the number of shares of Class A Common Stock to which such record holder of Class B Common Stock, or to which the nominee or nominees of such record holder, shall be entitled as aforesaid. Such conversion shall be deemed to have occurred immediately prior to the close of business on the date such notice of the election to convert is received by the Corporation, and the person or persons entitled to receive the shares of Class A Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Class A Common Stock as of such date. The

2. Automatic Conversion. Each share of Class B Common Stock shall automatically, without further action by the Corporation or the holder thereof, be converted into one (1) fully paid and nonassessable share of Class A Common Stock immediately prior to the close of business on the earlier of (i) ten (10) years from the Closing Date (as defined below) and (ii) the date specified by the affirmative vote of the holders of Class B Common Stock representing not less than two-thirds (2/3) of the voting power of the outstanding shares of Class B Common Stock, voting separately as a single class (each of the events referred to in (i) through (ii) are referred to herein as an “Automatic Conversion”). The Corporation shall provide notice of an Automatic Conversion of shares of Class B Common Stock pursuant to this Section 2 of Article V to record holders of such shares of Class B Common Stock as soon as practicable following the Automatic Conversion. Such notice shall be provided by any means then permitted by the General Corporation Law; provided, however, that no failure to give such notice nor any defect therein shall affect the validity of an Automatic Conversion. Upon and after an Automatic Conversion, the person registered on the Corporation’s books as the record holder of the shares of Class B Common Stock so converted immediately prior to an Automatic Conversion shall be registered on the Corporation’s books as the record holder of the shares of Class A Common Stock issued upon Automatic Conversion of such shares of Class B Common Stock, without further action on the part of the record holder thereof. Immediately upon the effectiveness of an Automatic Conversion, the rights of the holders of the shares of Class B Common Stock, converted pursuant to an Automatic Conversion shall cease, and the holders shall be treated for all purposes as having become the record holder or holders of such shares of Class A Common Stock into which such shares of Class B Common Stock were converted.

4. Policies and Procedures. The Corporation may, from time to time, establish such policies and procedures, not in violation of applicable law or this Restated Certificate of Incorporation or the Bylaws, relating to the conversion of shares of the Class B Common Stock into shares of Class A Common Stock as it may deem necessary or advisable. If the Corporation has reason to believe that a Transfer that is not a Permitted Transfer has occurred, the Corporation may request that the purported transferor furnish affidavits or other evidence to the Corporation as it reasonably deems necessary to determine whether a Transfer that is not a Permitted Transfer has occurred, and if such transferor does not within ten (10) days after the date of such request furnish sufficient (as determined by the Board of Directors (but not a committee thereof)) evidence to the Corporation (in the manner provided in the request) to enable the Corporation to determine that no such Transfer has occurred, any such shares of Class B Common Stock, to the extent not previously converted, shall be automatically converted into shares of Class A Common Stock on a one to one basis, and such conversion shall thereupon

be registered on the books and records of the Corporation. In connection with any action of stockholders taken at a meeting, the stock ledger of the Corporation shall be presumptive evidence as to who are the stockholders entitled to vote in person or by proxy at any meeting of stockholders and the classes of shares held by each such stockholder and the number of shares of each class held by such stockholder.

(f) “Permitted Entity” shall mean with respect to a Qualified Stockholder: (i) a Permitted Trust solely for the benefit of (A) such Qualified Stockholder, (B) one or more Family Members of such Qualified Stockholder, or (C) any other Permitted Entity of such Qualified Stockholder; or (ii) any general partnership, limited partnership, limited liability company, corporation or other entity exclusively owned by (A) such Qualified Stockholder, (B) one or more Family Members of such Qualified Stockholder, or (C) any other Permitted Entity of such Qualified Stockholder.

(g) “Permitted Foundation” shall mean with respect to a Qualified Stockholder: a trust or private non-operating foundation that is tax-exempt under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (the “Code”), so long as such Qualified Stockholder has dispositive power and Voting Control with respect to the shares of Class B Common Stock held by such trust or organization and the Transfer to such trust does not involve any payment of cash, securities, property or other consideration (other than an interest in such trust or organization) to such Qualified Stockholder.

(h) “Permitted IRA” shall mean an Individual Retirement Account, as defined in Section 408(a) of the Code, or a pension, profit sharing, stock bonus or other type of plan or trust of which a Qualified Stockholder is a participant or beneficiary and which satisfies the requirements for qualification under Section 401 of the Code; provided that in each case such Qualified Stockholder has sole dispositive power and exclusive Voting Control with respect to the shares of Class B Common Stock held in such account, plan or trust.

(k) “Permitted Trust” shall mean a bona fide trust where each trustee is (i) a Qualified Stockholder, (ii) a Family Member of such Qualified Stockholder, (iii) a professional in the business of providing trustee services, including private professional fiduciaries, trust companies and bank trust departments, or (iv) an individual who may be removed and replaced at the sole discretion of a Qualified Stockholder or a Family Member of such Qualified Stockholder.

(l) “Qualified Stockholder” shall mean: (i) the record holder of a share of Class B Common Stock as of the Closing Date; (ii) the initial record holder of any shares of Class B Common Stock that are originally issued by the Corporation after the Closing Date pursuant to the exercise, settlement, exchange or conversion of any Option or Convertible Security that, in each case, was outstanding as of the Closing Date; (iii) each natural person who, prior to the Closing Date, transferred shares of capital stock of the Corporation (or a company that combined with the Corporation or a subsidiary of the Corporation) to a Permitted Entity, Permitted Foundation or Permitted IRA that is or becomes a Qualified Stockholder; (iv) each natural person who transferred shares of, or equity awards for, Class B Common Stock (including any Option exercisable or Convertible Security exchangeable for or convertible into shares of Class B Common Stock) to a Permitted Entity, Permitted Foundation or Permitted IRA that is or becomes a Qualified Stockholder; and (v) a Permitted Transferee.

(ii) entering into a voting trust, agreement or arrangement (with or without granting a proxy) solely with stockholders who are holders of Class B Common Stock that (A) is disclosed either in a Schedule 13D filed with the Securities and Exchange Commission or in writing to the Secretary of the Corporation, (B) either has a term not exceeding one (1) year or is terminable by the holder of the shares subject thereto at any time and (C) does not involve any payment of cash, securities, property or other consideration to the holder of the shares subject thereto other than the mutual promise to vote shares in a designated manner;

(iv) the pledge of shares of Class B Common Stock by a stockholder that creates a mere security interest in such shares pursuant to a bona fide loan or indebtedness transaction for so long as such stockholder continues to exercise Voting Control over such pledged shares; provided, however, that a foreclosure on such shares or other similar action by the pledgee (including the exercise of any proxy authority granted to such pledgee pursuant to such pledge) shall constitute a Transfer unless such foreclosure or similar action qualifies as a Permitted Transfer;

(v) the fact that, as of the Closing Date or at any time after the Closing Date, the spouse of any holder of Class B Common Stock possesses or obtains an interest in such holder’s shares of Class B Common Stock arising solely by reason of the application of the community property laws of any jurisdiction, so long as no other event or circumstance shall exist or have occurred that constitutes a Transfer of such shares of Class B Common Stock;

A Transfer shall also be deemed to have occurred with respect to a share of Class B Common Stock beneficially held by (A) an entity that is a Permitted Entity, Permitted Foundation or Permitted IRA, if there occurs any act or circumstance that causes such entity to no longer be a Permitted Entity, Permitted Foundation or Permitted IRA or (B) an entity that is a Qualified Stockholder, if, in either case, there occurs a transfer on a cumulative basis, from and after the Closing Date, of a majority of the voting power of the voting securities, or securities that otherwise entitle a party to elect a majority of the members of the board of directors or governing body, of such entity or any direct or indirect Parent of such entity, other than a transfer to parties that are, as of the Closing Date, holders of voting securities of any such entity or Parent of such entity.

7. Effect of Conversion on Payment of Dividends. Notwithstanding anything to the contrary in Sections 1, 2 or 3 of this Article V, if the date on which any share of Class B Common Stock is converted into Class A Common Stock pursuant to the provisions of Sections 1, 2 or 3 of this Article V occurs after the record date for the determination of the holders of Class B Common Stock entitled to receive any dividend or distribution to be paid on the shares of Class B Common Stock, the holder of such shares of Class B Common Stock as of such

record date will be entitled to receive such dividend or distribution on such payment date; provided, that, notwithstanding any other provision of this Restated Certificate of Incorporation, to the extent that any such dividend or distribution is payable in shares of Class B Common Stock, such shares of Class B Common Stock shall automatically be converted to Class A Common Stock on a one-to-one basis.

8. Reservation. The Corporation shall at all times reserve and keep available, out of its authorized and unissued shares of Class A Common Stock, solely for the purpose of effecting conversions of shares of Class B Common Stock into Class A Common Stock, such number of duly authorized shares of Class A Common Stock as shall from time to time be sufficient to effect the conversion of all then-outstanding shares of Class B Common Stock. If at any time the number of authorized and unissued shares of Class A Common Stock shall not be sufficient to effect the conversion of all then-outstanding shares of Class B Common Stock, the Corporation shall promptly take such corporate action as may be necessary to increase its authorized but unissued shares of Class A Common Stock to such number of shares as shall be sufficient for such purpose, including, without limitation, obtaining the requisite stockholder approval of any necessary amendment to this Restated Certificate of Incorporation. All shares of Class A Common Stock which are so issuable shall, when issued, be duly and validly issued, fully paid and non-assessable shares. The Corporation shall take all such action as may be necessary to ensure that all such shares of Class A Common Stock may be so issued without violation of any applicable law or regulation.

9. Determinations by the Board of Directors. In case of an ambiguity in the application of any provision set forth in this Article V or in the meaning of any term or definition set forth in this Article V, the Board of Directors (but not a committee thereof), shall have the power to determine, in its sole discretion, the application of any such provision or any such term or definition with respect to any situation based on the facts believed in good faith by it. A determination of the Board of Directors in accordance with the preceding sentence shall be conclusive and binding on the stockholders of the Corporation. Such determination shall be evidenced in a writing adopted by the Board of Directors, and such writing shall be made available for inspection by any holder of capital stock of the Corporation at the principal executive offices of the Corporation.

The Board of Directors shall have the power to adopt, amend or repeal the Bylaws. Any adoption, amendment or repeal of the Bylaws by the Board of Directors shall require the approval of a majority of the Whole Board. For purposes of this Restated Certificate of Incorporation, the term “Whole Board” shall mean the total number of authorized directors whether or not there exist any vacancies in previously authorized directorships. The stockholders shall also have power to adopt, amend or repeal the Bylaws; provided, however, that, notwithstanding any other provision of this Restated Certificate of Incorporation or any provision of law that might otherwise permit a lesser or no vote, but in addition to any vote of the holders of any class or series of stock of the Corporation required by applicable law or by this Restated Certificate of Incorporation, the affirmative vote of the holders of at least two-thirds

(2/3) of the voting power of all of the then-outstanding shares of the capital stock of the Corporation entitled to vote thereon, voting together as a single class, shall be required for the stockholders to adopt, amend or repeal any provision of the Bylaws, provided, further, that, in the case of any proposed adoption, amendment or repeal of any provisions of the Bylaws that is approved by at least two-thirds (2/3) of the Whole Board and submitted to the stockholders for adoption thereby, then only the affirmative vote of the holders of a majority of the voting power of all of the then-outstanding shares of the capital stock of the Corporation entitled to vote thereon, voting together as a single class, shall be required to adopt, amend or repeal any such provision of the Bylaws.

2.1. The directors shall be divided, with respect to the time for which they severally hold office, into three classes as nearly equal in size as is practicable, designated as Class I, Class II and Class III, respectively (the “Classified Board”). The Board of Directors is authorized to assign members of the Board of Directors already in office to such classes of the Classified Board. The initial term of office of the Class I directors shall expire at the Corporation’s first annual meeting of stockholders following the Closing Date, the initial term of office of the Class II directors shall expire at the Corporation’s second annual meeting of stockholders following the Closing Date, and the initial term of office of the Class III directors shall expire at the Corporation’s third annual meeting of stockholders following the Closing Date. At each annual meeting of stockholders following the Closing Date, directors elected to succeed those directors of the class whose terms then expire shall be elected for a term of office expiring at the third succeeding annual meeting of stockholders after their election.

2.5. Any vacancy occurring in the Board of Directors for any cause, and any newly created directorship resulting from any increase in the authorized number of directors, shall be filled only by the affirmative vote of a majority of the directors then in office, even if less than a quorum, or by a sole remaining director, and shall not be filled by the stockholders. Any director elected in accordance with the preceding sentence shall hold office for a term expiring at the annual meeting of stockholders at which the term of office of the class to which the director has been assigned expires and until such director’s successor shall have been duly elected and qualified, or until such director’s earlier death, resignation, disqualification or removal.

2.7. In case of an ambiguity in the application of any provision set forth in this Section 2 of Article VII or in the meaning of any term or definition set forth in this Section 2 of Article VII (including any such term used in any other provision of this Restated Certificate of Incorporation), the Board of Directors, or a committee thereof, shall have the power to determine, in its sole discretion, the application of any such provision or any such term or definition with respect to any situation based on the facts believed in good faith by it. A determination of the Board of Directors (or a committee thereof, as applicable) in accordance with the preceding sentence shall be conclusive and binding on the stockholders of the Corporation. Such determination shall be evidenced in a writing adopted by the Board of Directors (or a committee thereof, as applicable), and such writing shall be made available for inspection by any holder of capital stock of the Corporation at the principal executive offices of the Corporation.

1. Limitation of Liability. To the fullest extent permitted by law, no director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. Without limiting the effect of the preceding sentence, if the General Corporation Law is hereafter amended to authorize the further elimination or limitation of the liability of a director, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law, as so amended.

2. Special Meeting of Stockholders. Special meetings of the stockholders of the Corporation may be called only by the Chairperson of the Board of Directors, the Chief Executive Officer, the Lead Independent Director (as defined in the Bylaws) or the Board of Directors acting pursuant to a resolution adopted by a majority of the Whole Board, and may not be called by the stockholders or any other person or persons.

3. Advance Notice of Stockholder Nominations and Business Transacted at Special Meetings. Advance notice of stockholder nominations for the election of directors of the Corporation and of business to be brought by stockholders before any meeting of stockholders of the Corporation shall be given in the manner provided in the Bylaws. Business transacted at special meetings of stockholders shall be limited to the purpose or purposes stated in the notice of meeting.

If any provision of this Restated Certificate of Incorporation shall be held to be invalid, illegal, or unenforceable, then such provision shall nonetheless be enforced to the maximum extent possible consistent with such holding and the remaining provisions of this Restated Certificate of Incorporation (including without limitation, all portions of any section of this Restated Certificate of Incorporation containing any such provision held to be invalid, illegal, or unenforceable, which is not invalid, illegal, or unenforceable) shall remain in full force and effect.

1. General. The Corporation reserves the right to amend or repeal any provision contained in this Restated Certificate of Incorporation in the manner prescribed by the laws of the State of Delaware and all rights conferred upon stockholders are granted subject to this reservation; provided, however, that, notwithstanding any provision of this Restated Certificate of Incorporation (including any Certificate of Designation) or any provision of law that might otherwise permit a lesser vote or no vote (but subject to Section 2 of Article IV hereof), but in addition to any vote of the holders of any class or series of the stock of the Corporation required by law or by this Restated Certificate of Incorporation (including any Certificate of Designation), and subject to Sections 1 and 2.1 of Article IV, the affirmative vote of the holders of at least two-

thirds (2/3) of the voting power of all of the then-outstanding shares of the capital stock of the Corporation entitled to vote thereon, voting together as a single class, shall be required to amend or repeal, or adopt any provision inconsistent with, this Section 1 of this Article XI, Sections 1.2 and 2 of Article IV, or Article V, Article VI, Article VII, Article VIII, Article IX, Article X or Article XII (the “Specified Provisions”); provided, further, that, if two-thirds (2/3) of the Whole Board has approved such amendment or repeal of, or any provision inconsistent with, the Specified Provisions, then only the affirmative vote of the holders of a majority of the voting power of all of the then-outstanding shares of the capital stock of the Corporation entitled to vote thereon, voting together as a single class (in addition to any other vote of the holders of any class or series of stock of the Corporation required by law or by this Restated Certificate of Incorporation, including any Certificate of Designation), shall be required to amend or repeal, or adopt any provision inconsistent with, the Specified Provisions. Notwithstanding anything to the contrary herein, prior to an Automatic Conversion, and in addition to any other vote required pursuant to this Article XI, the Corporation shall not, without the prior affirmative vote of the holders of at least two-thirds (2/3) of the then-outstanding shares of Class B Common Stock, voting separately as a single class:
