The designations and the powers, privileges and rights, and the qualifications, limitations or restrictions thereof in respect of each class of capital stock of the Corporation are as follows:

A. COMMON STOCK

General. The voting, dividend, liquidation and other rights and powers of the Common Stock are subject to and qualified by the rights, powers and preferences of any series of Preferred Stock as may be designated by the board of directors of the Corporation (the “Board of Directors”) and outstanding from time to time.

Voting. Except as otherwise provided herein or expressly required by law, each holder of Common Stock, as such, shall be entitled to vote on each matter submitted to a vote of stockholders generally and shall be entitled to (i) one (1) vote for each share of Class A Common Stock and (ii) twenty (20) votes for each share of Class B Common Stock, in each case, held of record by such holder as of the record date for determining stockholders entitled to vote on such matter. Except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Amended and Restated Certificate, as may be amended and/or restated from time to time (including any Certificate of Designation (as defined below)) that relates solely to the rights, powers, preferences (or the qualifications, limitations or restrictions thereof) or other terms of one or more outstanding series of Preferred Stock or other classes of Common Stock if the holders of such affected series of Preferred Stock or Common Stock, as applicable, are entitled exclusively, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Amended and Restated Certificate (including any Certificate of Designation) or pursuant to the DGCL.

Except as otherwise required pursuant to this Amended and Restated Certificate and subject to the rights of any holders of any outstanding series of Preferred Stock, the number of authorized shares of each class of Common Stock or 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 stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto).

Except as otherwise required in this Amended and Restated Certificate or by the DGCL, the holders of Common Stock will vote together as a single class on all matters (or, if any holders of Preferred Stock are entitled to vote together with such holders of Common Stock, as a single class with the holders of Preferred Stock).

Dividends.

(i)

Subject to applicable law and the rights and preferences of any holders of any outstanding series of Preferred Stock, the holders of Common Stock, as such, shall be entitled to the payment of dividends on the Common Stock when, as and if declared by the Board of Directors in accordance with applicable law.

(ii)

Dividends of cash or property may not be declared or paid on any class of Common Stock unless a dividend of the same amount per share and same type of cash or property (or combination thereof) per share is concurrently declared or paid on the other classes of outstanding Common Stock.

(iii)

In no event will any stock dividend, stock split, reverse stock split, combination of stock, subdivision, exchange, reclassification or recapitalization be declared or made on any class of Common Stock (each, a “Stock Adjustment”) unless a corresponding Stock Adjustment for all other classes of Common Stock at the time outstanding is made in the same proportion and the same manner (unless such requirement is waived in advance by the written consent or affirmative vote of the holders of shares representing a majority of the voting power of any such other class of Common Stock (voting separately as a single class), in which event, no such Stock Adjustment need be made for such other class of Common Stock). Stock dividends with respect to each class of Common Stock may only be paid with shares of stock of the same class of Common Stock.

Liquidation. Subject to the rights and preferences of any holders of any shares of any outstanding series of Preferred Stock, in the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, the funds and assets of the Corporation that may be legally distributed to the Corporation’s stockholders shall be distributed among the holders of the then outstanding Common Stock pro rata in accordance with the number of shares of Common Stock held by each such holder.

Merger, Consolidation, Tender or Exchange Offer. Except as expressly provided in this Article V, all shares of Common Stock shall, as among each other, have the same rights, preferences and privileges and rank equally, share ratably and be identical in all respects as to all matters (unless holders of shares representing a majority of the voting power of any outstanding class of Common Stock (voting separately as a single class) waive such requirement in advance and in writing as to different treatment of such class of Common Stock, in which event different treatment may be permitted for such class of Common Stock). Without limiting the generality of the foregoing, unless such requirement as to different treatment of such class of Common Stock is waived in advance by the affirmative vote or written consent of holders of shares representing a majority of the voting power of any outstanding class of Common Stock (voting separately as a single class), in which event, different treatment may be permitted for such class of Common Stock, (i) in the event of a merger, consolidation or other business combination requiring the approval of the holders of the Corporation’s capital stock entitled to vote thereon (whether or not the Corporation is the surviving entity), the holders of any class of Common Stock shall have the right to receive, or the right to elect to receive, the same form of consideration, if any, as the holders of any other class of Common Stock, and the holders of any class of Common Stock shall have the right to receive, or the right to elect to receive, at least the same amount of consideration, if any, on a per share basis as the holders of any other class of Common Stock, and (ii) in the event of (a) any tender or exchange offer to acquire any shares of Common Stock by any third party pursuant to an agreement to which the Corporation is a party or (b) any tender or exchange offer by the Corporation to acquire any shares of Common Stock, pursuant to the terms of the applicable tender or exchange offer, the holders of any class of Common Stock shall have the right to receive, or the right to elect to receive, the same form of consideration, if any, as the holders of any other class of Common Stock, and the holders of any class of Common Stock shall have the right to receive, or the right to elect to receive, at least the same amount of consideration, if any, on a per share basis as the holders of any other class of Common Stock; provided that, for the purposes of the foregoing clauses (i) and (ii) and notwithstanding the first sentence of this Article V, Section A.5, in the event any such consideration includes securities, the consideration payable to holders of Class B Common Stock shall be deemed the same form of consideration and at least the same amount of consideration on a per share basis as the holders of Class A Common Stock on a per share basis if the only difference in the per share distribution to the holders of Class B Common Stock is that each share of the securities distributed to such holders has twenty (20) times the voting power of each share of the securities distributed to the holder of a share of Class A Common Stock.

Transfer Rights. Subject to applicable law and the transfer restrictions set forth in the Bylaws and Article V, Section A.7 of this Amended and Restated Certificate, shares of Common Stock and the rights and obligations associated therewith shall be fully transferable to any transferee.

Conversion of Class B Common Stock.

(i)

Voluntary Conversion. Each share of Class B Common Stock shall be convertible into one share of Class A Common Stock at the option of the holder thereof at any time upon written notice to the transfer agent of the Corporation.

(ii)

Automatic Conversion. Each share of Class B Common Stock shall automatically, without any further action, convert into one share of Class A Common Stock upon a Transfer, other than to a Qualified Stockholder, of such share.

(iii)

Procedures. The Corporation may, from time to time, establish such policies and procedures relating to the conversion of Class B Common Stock into Class A Common Stock and the general administration of this multi-class stock structure, including the issuance of stock certificates (or the establishment of book-entry positions) with respect thereto, as it may deem reasonably necessary or advisable, and may from time to time request that holders of shares of Class B Common Stock furnish certifications, affidavits or other proof to the Corporation as it deems necessary to verify the ownership of Class B Common Stock and to confirm that a conversion into Class A Common Stock has not occurred. A determination in good faith by the Secretary of the Corporation that a Transfer results or has resulted in a conversion into Class A Common Stock shall be conclusive and binding.

(iv)

Immediate Effect of Conversion. In the event of a conversion of shares of Class B Common Stock into shares of Class A Common Stock pursuant to this Article V, Section A.7, such conversion(s) shall be deemed to have been made at the time that the Transfer of shares occurred. Upon any conversion of Class B Common Stock into Class A Common Stock, all rights of the holder of shares of Class B Common Stock shall cease and the person or persons in whose names or names the certificate or certificates (or book-entry position(s)) representing the shares of Class A Common Stock are to be issued shall be treated for all purposes as having become the record holder or holders of such shares of Class A Common Stock. Shares of Class B Common Stock that are converted into shares of Class A Common Stock as provided in this Article V, Section A.7 shall be retired and may not be reissued.

(v)

Reservation of Stock. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Class A Common Stock, solely for the purpose of effecting the conversion of the shares of Class B Common Stock, such number of shares of Class A Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Class B Common Stock into shares of Class A Common Stock.

No Further Issuances. Except for a dividend payable in accordance with Article V, Section A.3 or a Stock Adjustment effectuated in accordance with Article V, Section A.3, the Corporation shall not at any time after the effective date of this Amended and Restated Certificate issue any additional shares of Class B Common Stock, unless such issuance is approved by the affirmative vote of the holders of a majority of the outstanding shares of Class A Common Stock, voting as a separate class.

ARTICLE VI

For the management of the business and for the conduct of the affairs of the Corporation it is further provided that:

A. The directors of the Corporation shall be classified with respect to the time for which they severally hold office into three classes, designated as 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 whole Board of Directors. The initial Class I directors shall serve for a term expiring at the 2027 annual meeting of the stockholders of the Corporation; the initial Class II directors shall serve for a term expiring at the 2028 annual meeting of the stockholders of the Corporation; and the initial Class III directors shall serve for a term expiring at the 2029 annual meeting of stockholders of stockholders at the Corporation. At each annual meeting of stockholders of the Corporation beginning with the 2027 annual meeting of stockholders, the successors of the class of directors whose term expires at that meeting shall be elected to hold office for a term expiring at the annual meeting of stockholders held in the third year following the year of their election. If the number of such 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 such additional director of any class elected to fill a newly created directorship 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 shall a decrease in the number of directors remove or shorten the term of any incumbent director. Any such director shall hold office until the annual meeting at which his or her term expires and until his or her successor shall be elected and qualified, or his or her death, resignation, retirement, disqualification or removal from office. The Board of Directors is authorized to assign members of the Board of Directors already in office to their respective class. Each director shall hold office until his or her successor is duly elected and qualified or until his or her earlier death, resignation, disqualification or removal in accordance with this Amended and Restate Certificate.

B. Except as otherwise expressly provided by the DGCL or this Amended and Restate Certificate, the business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. The number of directors that shall constitute the whole Board of Directors shall be fixed exclusively by one or more resolutions adopted from time to time by the Board of Directors in accordance with the Bylaws.

C. Subject to the special rights of the holders of one or more outstanding series of Preferred Stock to elect directors, the Board of Directors or any individual director may be removed from office at any time only for cause and then only by the affirmative vote of the holders of at least 66⅔% of the voting power of all the then outstanding shares of voting stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class.

D. Subject to the special rights of the holders of one or more outstanding series of Preferred Stock to elect directors, except as otherwise provided by law, any vacancies on the Board of Directors resulting from death, resignation, disqualification, retirement, removal or other causes and any newly created directorships resulting from any increase in the number of directors shall be filled (i) after no shares of Class B Common Stock are outstanding, by the affirmative vote of a majority of the directors then in office, even though less than a quorum, or by a sole remaining director and, (ii) when any shares of Class B Common Stock are outstanding, only by the affirmative vote of the holders of at least a majority of the voting power of all of the then outstanding shares of voting stock of the Corporation entitled to vote at an election of directors.

E. Whenever the holders of any one or more series of Preferred Stock issued by the Corporation shall have the right, voting separately as a series or separately as a class with one or more such other series, to elect directors at an annual or special meeting of stockholders, the election, term of office, removal and other features of such directorships shall be governed by the terms of this Amended and Restated Certificate (including any Certificate of Designation). Notwithstanding anything to the contrary in this Article VI, the number of directors that may be elected by the holders of any such series of Preferred Stock shall be in addition to the number fixed pursuant to paragraph B of this Article VI, and the total number of directors constituting the whole Board of Directors shall be automatically adjusted accordingly. Except as otherwise provided in the Certificate of Designation(s) in respect of one or more series of Preferred Stock, whenever the holders of any series of Preferred Stock having such right to elect additional directors are divested of such right pursuant to the provisions of such Certificate of Designation(s), the terms of office of all such additional directors elected by the holders of such series of Preferred Stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate (in which case each such director thereupon shall cease to be qualified as, and shall cease to be, a director) and the total authorized number of directors of the Corporation shall automatically be reduced accordingly.

F. In furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized to adopt, amend or repeal the Bylaws, without the assent or vote of the stockholders of the Corporation entitled to vote with respect thereto in any manner not inconsistent with the laws of the State of Delaware or this Amended and Restated Certificate. Notwithstanding anything to the contrary contained in this Amended and Restated Certificate or any provision of law that might otherwise permit a lesser vote of the stockholders, 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 Amended and Restated Certificate (including any Certificate of Designation(s) in respect of one or more series of Preferred Stock) or the Bylaws of the Corporation, the adoption, amendment or repeal of the Bylaws of the Corporation by the stockholders of the Corporation shall require the affirmative vote of the holders of at least 66⅔% of the voting power of all of the then outstanding shares of voting stock of the Corporation entitled to vote generally in an election of directors.

G. The directors of the Corporation need not be elected by written ballot unless the Bylaws so provide.

ARTICLE VII

A. Any action required or permitted to be taken by the stockholders of the Corporation may be effected at a duly called annual or special meeting of stockholders or may, except as otherwise required by applicable law or this Amended and Restated Certificate, be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, shall be signed by the holders of outstanding shares of stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation in accordance with the applicable provisions of the DGCL.

B. Subject to the special rights of the holders of one or more series of Preferred Stock, and to the requirements of applicable law, special meetings of the stockholders of the Corporation may be called for any purpose or purposes, at any time only (i) by or at the direction of the Board of Directors, the Chairperson of the Board of Directors or the Chief Executive Officer, in each case, in accordance with the Bylaws, or (ii) by the Secretary of the Corporation upon the request, in writing, of any holder of record of at least 25% of the voting power of the issued and outstanding shares of stock of the Corporation. Any such special meeting so called may be postponed, rescheduled or cancelled by the Board of Directors or other person calling the meeting.

C. Advance notice of stockholder nominations for the election of directors and of other business proposed to be brought by stockholders before any meeting of the stockholders of the Corporation shall be given in the manner provided in the Bylaws. Any business transacted at any special meeting of stockholders shall be limited to matters relating to the purpose or purposes identified in the notice of meeting.

ARTICLE VIII

No director of the Corporation shall have any personal liability to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or hereafter may be amended. Any amendment, repeal or modification of this Article VIII, or the adoption of any provision of this Amended and Restated Certificate inconsistent with this Article VIII, shall not adversely affect any right or protection of a director of the Corporation with respect to any act or omission occurring prior to such amendment, repeal, modification or adoption. If the DGCL is amended after approval by the stockholders of this Article VIII to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL as so amended.

ARTICLE IX

A. Subject to Article IX, Section C, the Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation), by reason of the fact that such person is or was a director or officer of the Corporation, or while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that such person’s conduct was unlawful.

B. Subject to Article IX(C), the Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the Corporation, or while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation; except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

C. Any indemnification under this Article IX (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the present or former director or officer is proper in the circumstances because such person has met the applicable standard of conduct set forth in Article IX(A) or Article IX(B), as the case may be. Such determination shall be made, with respect to a person who is a director or officer at the time of such determination, (i) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors designated by a majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion or (iv) by the stockholders. Such determination shall be made, with respect to former directors and officers, by any person or persons having the authority to act on the matter on behalf of the Corporation. To the extent, however, that a present or former director or officer of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith, without the necessity of authorization in the specific case.

D. For purposes of any determination under Article IX(C), a person shall be deemed to have acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, or, with respect to any criminal action or proceeding, to have had no reasonable cause to believe such person’s conduct was unlawful, if such person’s action is based on the records or books of account of the Corporation or another enterprise, or on information supplied to such person by the officers of the Corporation or another enterprise in the course of their duties, or on the advice of legal counsel for the Corporation or another enterprise or on information or records given or reports made to the Corporation or another enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Corporation or another enterprise. The provisions of this Article IX(D) shall not be deemed to be exclusive or to limit in any way the circumstances in which a person may be deemed to have met the applicable standard of conduct set forth in Article IX(A) or Article IX(B), as the case may be.

E. Notwithstanding any contrary determination in the specific case under Article IX(C), and notwithstanding the absence of any determination thereunder, any director or officer may apply to the Court of Chancery of the State of Delaware or any other court of competent jurisdiction in the State of Delaware for indemnification to the extent otherwise permissible under Article IX(A) or Article IX(B). The basis of such indemnification by the Corporation shall be a determination by such court that indemnification of the director or officer is proper in the circumstances because such person has met the applicable standard of conduct set forth in Article IX(A) or Article IX(B), as the case may be. Neither a contrary determination in the specific case under Article IX(C) nor the absence of any determination thereunder shall be a defense to such application or create a presumption that the director or officer seeking indemnification has not met any applicable standard of conduct. Notice of any application for indemnification pursuant to this Article IX shall be given to the Corporation promptly upon the filing of such application. If successful, in whole or in part, the director or officer seeking indemnification shall also be entitled to be paid the expense of prosecuting such application.

F. Expenses (including attorneys’ fees) incurred by a present or former director or officer in appearing at, participating in or defending any civil, criminal, administrative or investigative action, suit or proceeding in advance of its final disposition or in connection with a proceeding brought to establish or enforce a right to indemnification or advancement of expenses under this Article IX shall be paid by the Corporation upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation as authorized in this Article IX. Such expenses (including attorneys’ fees) incurred by employees and agents of the Corporation or by persons acting at the request of the Corporation as directors, officers, employees or agents of another corporation, partnership, joint venture, trust or other enterprise may be so paid upon such terms and conditions, if any, as the Corporation deems appropriate.

G. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article IX shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under this Amended and Restated Certificate, the Bylaws, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office, it being the policy of the Corporation that indemnification of the persons specified in Article IX(A) or Article IX(B) shall be made to the fullest extent permitted by law. The provisions of this Article IX shall not be deemed to preclude the indemnification of any person who is not specified in Article IX(A) or Article IX(B) but whom the Corporation has the power or obligation to indemnify under the provisions of the DGCL, or otherwise.

H. The Corporation may purchase and maintain insurance on behalf of any person who is or was a director or officer of the Corporation, or is or was a director or officer of the Corporation serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Corporation would have the power or the obligation to indemnify such person against such liability under the provisions of this Article IX.

I. For purposes of this Article IX, references to “the Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors or officers, so that any person who is or was a director or officer of such constituent corporation, or is or was a director or officer of such constituent corporation serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Article IX with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued. The term “another enterprise” as used in this Article IX shall mean any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise of which such person is or was serving at the request of the Corporation as a director, officer, employee or agent. For purposes of this Article IX, references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the Corporation” shall include any service as a director, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such director or officer with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Corporation” as referred to in this Article IX.

J. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article IX shall, unless otherwise provided when authorized or ratified as provided in this Article IX, continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

K. Notwithstanding anything contained in this Article IX to the contrary, except for proceedings to enforce rights to indemnification (which shall be governed by Article IX, Section E), the Corporation shall not be obligated to indemnify any present or former director or officer (or his or her heirs, executors or personal or legal representatives) or advance expenses in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized or consented to by the Board of Directors.

L. The Corporation may, to the extent authorized from time to time by the Board of Directors, provide rights to indemnification and to the advancement of expenses to employees and agents of the Corporation and to persons serving at the request of the Corporation as directors, officers, employees and agents of another corporation, partnership, joint venture, trust or other enterprise similar to those conferred in this Article IX to directors and officers of the Corporation.

M. Notwithstanding that a director, officer, employee or agent of the Corporation (collectively, the “Covered Persons”) may have certain rights to indemnification, advancement of expenses and/or insurance provided by other persons (collectively, the “Other Indemnitors”), with respect to the rights to indemnification, advancement of expenses and/or insurance set forth herein, the Corporation: (i) shall be the indemnitor of first resort (i.e., its obligations to Covered Persons are primary and any obligation of the Other Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Covered Persons are secondary); and (ii) shall be required to advance the full amount of expenses incurred by Covered Persons and shall be liable for the full amount of all liabilities, without regard to any rights Covered Persons may have against any of the Other Indemnitors. No advancement or payment by the Other Indemnitors on behalf of Covered Persons with respect to any claim for which Covered Persons have sought indemnification from the Corporation shall affect the immediately preceding sentence, and the Other Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Covered Persons against the Corporation. Notwithstanding anything to the contrary herein, the obligations of the Corporation under this Article IX(M) shall only apply to Covered Persons in their capacity as Covered Persons.

N. Any repeal or amendment of this Article IX by the Board of Directors or the stockholders of the Corporation or by changes in applicable law, or the adoption of any other provision of this Amended and Restated Certificate inconsistent with this Article IX, will, to the extent permitted by applicable law, be prospective only (except to the extent such amendment or change in applicable law permits the Corporation to provide broader indemnification rights to Indemnitees on a retroactive basis than permitted prior thereto), and will not in any way diminish or adversely affect any right or protection existing hereunder in respect of any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision.

ARTICLE X

A. Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery (the “Chancery Court”) of the State of Delaware (or, in the event that the Chancery Court does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) and any appellate court thereof shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action, suit or proceeding brought on behalf of the Corporation, (ii) any action, suit or proceeding asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, stockholder or employee of the Corporation to the Corporation or to the Corporation’s stockholders, (iii) any action, suit or proceeding arising pursuant to any provision of the DGCL or the Bylaws or this Amended and Restated Certificate (as either may be amended from time to time), (iv) any action, suit or proceeding as to which the DGCL confers jurisdiction on the Chancery Court, or (v) any action, suit or proceeding asserting a claim against the Corporation or any current or former director, officer or stockholder governed by the internal affairs doctrine. If any action the subject matter of which is within the scope of the immediately preceding sentence is filed in a court other than the courts in the State of Delaware (a “Foreign Action”) in the name of any stockholder, such stockholder shall be deemed to have consented to (i) the personal jurisdiction of the state and federal courts in the State of Delaware in connection with any action brought in any such court to enforce the provisions of the immediately preceding sentence and (ii) having service of process made upon such stockholder in any such action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder. Notwithstanding the foregoing, the provisions of this Article X(A) shall not apply to suits brought to enforce any liability or duty created by the Securities Act of 1933, as amended (the “Securities Act”), the Exchange Act or any other claim for which the federal courts of the United States have exclusive jurisdiction.

B. Unless the Corporation consents in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act.

C. Any person or entity purchasing or otherwise acquiring any interest in any security of the Corporation shall be deemed to have notice of and consented to this Article X.

ARTICLE XI

A. Notwithstanding anything contained in this Certificate of Incorporation to the contrary, in addition to any vote required by applicable law, the following provisions in this Amended and Restated Certificate may not be amended, altered, repealed or rescinded, in whole or in part, and no provision inconsistent therewith or herewith may be adopted, without the affirmative vote of the holders of at least 66⅔% of the total voting power of all the then outstanding shares of stock of the Corporation entitled to vote thereon, voting together as a single class: Article V, Article VI, Article VII, Article VIII, Article IX, Article X, and this Article XI; provided, however, that, in addition to any other vote required by law or this Certificate of Incorporation, any amendment to this Amended and Restated Certificate that (i) increases the voting power of the Class B Common Stock pursuant to Article V, Section A.2 or (ii) alters or changes Article V, Section A.7 in a manner that adversely affects the holders of Class A Common Stock shall not be approved, in each case, without the affirmative vote of the holders of at least a majority of the total voting power of all then-outstanding shares of Class A Common Stock of the Corporation entitled to vote thereon, voting as a separate class.

B. If any provision or provisions of this Amended and Restated Certificate shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever: (i) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Amended and Restated Certificate (including, without limitation, each portion of any paragraph of this Amended and Restated Certificate containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not, to the fullest extent permitted by applicable law, in any way be affected or impaired thereby and (ii) to the fullest extent permitted by applicable law, the provisions of this Amended and Restated Certificate (including, without limitation, each such portion of any paragraph of this Amended and Restated Certificate containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Corporation to protect its directors, officers, employees and agents from personal liability in respect of their good faith service to or for the benefit of the Corporation to the fullest extent permitted by law.
