I. Capital Stock.

A.Common Stock and Preferred Stock may be issued from time to time by the Corporation for such consideration as may be fixed by the Board of Directors of the Corporation. The Board of Directors is hereby expressly authorized, by resolution or resolutions, to provide, out of the unissued shares of Preferred Stock, for one or more series of Preferred Stock and, with respect to each such series, to fix, without further stockholder approval, the designation of such series, the powers (including voting powers), preferences and relative, participating, optional and other special rights, and the qualifications, limitations or restrictions thereof, of such series of Preferred Stock and the number of shares of such series. The powers, preferences and relative, participating, optional and other special rights of, and the qualifications, limitations or restrictions thereof, of each series of Preferred Stock, if any, may differ from those of any and all other series at any time outstanding.

B.Each holder of record of Common Stock, as such, shall have one vote for each share of Common Stock which is outstanding in his, her or its name on the books of the Corporation on all matters on which stockholders are entitled to vote generally. Except as otherwise required by law, holders of Common Stock shall not be entitled to vote on any amendment to this Third Amended and 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 with the holders of one or more other such series, to vote thereon pursuant to this Third Amended and Restated Certificate of Incorporation (including any certificate of designation relating to any series of Preferred Stock) or pursuant to the DGCL.

C.Except as otherwise required by law, holders of any series of Preferred Stock shall be entitled to only such voting rights, if any, as shall expressly be granted thereto by this Third Amended and Restated Certificate of Incorporation (including any certificate of designation relating to such series of Preferred Stock).

D.Subject to applicable law and the rights, if any, of the holders of any outstanding series of Preferred Stock or any class or series of stock having a preference over or the right to participate with the Common Stock with respect to the payment of dividends, dividends may be declared and paid ratably on the Common Stock out of the assets of the Corporation which are legally available for this purpose at such times and in such amounts as the Board of Directors in its discretion shall determine.

E.Upon the dissolution, liquidation or winding up of the Corporation, after payment or provision for payment of the debts and other liabilities of the Corporation and subject to the rights, if any, of the holders of any outstanding series of Preferred Stock or any class or series of stock having a preference over or the right to participate with the Common Stock with respect to the distribution of assets of the Corporation upon such dissolution, liquidation or winding up of the Corporation, the holders of Common Stock shall be entitled to receive the remaining assets of the Corporation available for distribution to its stockholders ratably in proportion to the number of shares held by them.

F.The number of authorized shares of Preferred Stock or 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 in voting power of the stock of the Corporation entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto), and no vote of the holders of any of the Common Stock or the Preferred Stock voting separately as a class shall be required therefor, unless a vote of any such holder is required pursuant to this Third Amended and Restated Certificate of Incorporation (including any certificate of designation relating to any series of Preferred Stock).

ARTICLE V

AMENDMENT OF THE CERTIFICATE OF INCORPORATION AND BYLAWS

A.Notwithstanding anything contained in this Third Amended and Restated Certificate of Incorporation to the contrary, in addition to any vote required by applicable law, the following provisions in this Third Amended and Restated Certificate of Incorporation may be amended, altered, repealed or rescinded, in whole or in part, or any provision inconsistent therewith or herewith may be adopted, only by the affirmative vote of the holders of at least 66-2/3% in voting power of all the then-outstanding shares of stock of the Corporation entitled to vote thereon, voting together as a single class: this Article V, Sections (A), (B) and (C) of Article VI, Article VII, Article VIII and Article IX; provided, however, that the provisions of this sentence relating to Sections (A) and (C) of Article VI will expire at the 2021 annual meeting of stockholders. For the purposes of this Third Amended and Restated Certificate of Incorporation, beneficial ownership of shares shall be determined in accordance with Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any successor provision thereto.

B.The Board of Directors is expressly authorized to make, repeal, alter, amend and rescind, in whole or in part, the bylaws of the Corporation (as in effect from time to time, the “Bylaws”) without the assent or vote of the stockholders in any manner not inconsistent with the laws of the State of Delaware or this Third Amended and Restated Certificate of Incorporation. Notwithstanding anything to the contrary contained in this Third Amended and Restated Certificate of Incorporation, the affirmative vote of a majority in voting power of all the then-outstanding shares of stock of the Corporation entitled to vote thereon, voting together as a single class, shall be required in order for the stockholders of the Corporation to alter, amend, repeal or rescind, in whole or in part, any provision of the Bylaws or to adopt any provision inconsistent therewith.

ARTICLE VI

BOARD OF DIRECTORS

A.The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. Except as otherwise provided for or fixed pursuant to the provisions of Article IV (including any certificate of designation with respect to any series of Preferred Stock) and this Article VI relating to the rights of the holders of any series of Preferred Stock to elect additional directors, the total number of directors shall be determined from time to time exclusively by resolution adopted by the Board of Directors.

1. Beginning at the 2021 annual meeting of stockholders, directors shall be elected to hold office for a one-year term expiring at the next annual meeting of stockholders, and the directors shall not be divided into classes, with all directors elected at the 2021 annual meeting of stockholders and each annual meeting thereafter being elected in accordance with this Section (A)(1) of Article VI; provided that, prior to the 2021 annual meeting of stockholders, the Board of Directors shall be divided into classes in the manner set forth below in Section (A)(2) of this Article VI. The term of each director shall continue until the annual meeting at which such director’s term expires and until such director’s successor shall be elected and qualified, or, if earlier, such

director’s death, resignation, retirement, disqualification or removal from office.

2. Solely with respect to directors holding office prior to the 2021 annual meeting of stockholders (other than those directors elected by the holders of any series of Preferred Stock, voting separately as a series or together with one or more other such series, as the case may be), the directors shall be divided into three classes designated Class I,Class II and Class III. Each class shall consist, as nearly as possible, of one-third of the total number of such directors. 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 such director’s term expires and until such director’s successor shall be elected and qualified, or such director’s death, resignation, retirement, disqualification or removal from office. The Board of Directors is authorized to assign members of the Board of Directors to their respective classes. The Class I directors or such directors’ successors shall hold office for a term expiring at the 2021 annual meeting of stockholders. At the 2019 annual meeting of stockholders, the Class II directors or such directors’ successors shall be elected to hold office for a one-year term expiring at the 2020 annual meeting of stockholders. At the 2020 annual meeting of stockholders, the Class III directors or such directors’ successors shall be elected to hold office for a one-year term expiring at the 2021 annual meeting of stockholders.

B.Subject to the rights granted to the holders of any one or more series of Preferred Stock then outstanding, any newly created directorship on the Board of Directors that results from an increase in the number of directors and any vacancy occurring in the Board of Directors (whether by death, resignation, retirement, disqualification, removal or other cause) shall be filled by a majority of the directors then in office, although less than a quorum, or by a sole remaining director. Any director elected to fill a vacancy occurring in the Board of Directors (whether by death, resignation, retirement, disqualification, removal or other cause) shall hold office for a term equal to the then-existing remainder of the term of the director originally elected to hold the directorship now vacant and shall remain in office until such director’s successor shall be elected and qualified, or such director’s earlier death, resignation, retirement, disqualification or removal. Any director elected to fill a newly created directorship on the Board of Directors resulting from an increase in the number of directors shall hold office for a term expiring at the next annual meeting of stockholders and shall remain in office until such director’s successor shall be elected and qualified, or until such director’s earlier death, resignation, retirement, disqualification or removal.

C.Any or all of the directors elected (other than the directors elected by the holders of any series of Preferred Stock of the Corporation, voting separately as a series or together with one or more other such series, as the case may be) for a term of more than one year (as well as any successor to such director if such director does not serve the entirety of such term) may be removed from office at any time but only for cause and only by the affirmative vote of a majority in voting power of all the then-outstanding shares of stock of the Corporation entitled to vote thereon, voting together as a single class. Except as set

forth in the immediately preceding sentence, any or all of the directors (other than the directors elected by the holders of any series of Preferred Stock of the Corporation, voting separately as a series or together with one or more other such series, as the case may be) may be removed from office at any time, with or without cause, by the affirmative vote of a majority in voting power of all the then-outstanding shares of stock of the Corporation entitled to vote thereon, voting together as a single class.

D.Elections of directors need not be by written ballot unless the Bylaws shall so provide.

E.During any period when the holders of any series of Preferred Stock have the right to elect additional directors pursuant to the provisions of such Preferred Stock, then upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of directors of the Corporation shall automatically be increased by such specified number of directors, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions, and (ii) each such additional director shall serve until such director’s successor shall have been duly elected and qualified, or until such director’s right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to such director’s earlier death, resignation, retirement, disqualification or removal. Except as otherwise provided by the Board of Directors in the resolution or resolutions establishing such series, 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 Preferred Stock, the terms of office of all such additional directors elected by the holders of such stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate and the total authorized number of directors of the Corporation shall be reduced accordingly.

ARTICLE VII

LIMITATION OF DIRECTOR LIABILITY

A.To the fullest extent permitted by the DGCL or any other law of the State of Delaware (as they exist on the date hereof or as they may hereafter be amended), a director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty owed to the Corporation or its stockholders.

B.Neither the amendment nor repeal of this Article VII, nor the adoption of any provision of this Third Amended and Restated Certificate of Incorporation, nor, to the fullest extent permitted by the DGCL or any other law of the State of Delaware (as they exist on the date hereof or as they may hereafter be amended), any modification of law shall eliminate, reduce or otherwise adversely affect any right or protection of a current or former director of the Corporation existing at the time of such amendment, repeal, adoption or modification.

ARTICLE VIII

CONSENT OF STOCKHOLDERS IN LIEU OF MEETING, ANNUAL AND SPECIAL MEETINGS OF STOCKHOLDERS

A.Any action required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of such holders and may not be effected by any consent in writing by such holders; provided, however, that any action required or permitted to be taken by

the holders of Preferred Stock, voting separately as a series or separately as a class with one or more other such series, may be taken without a meeting, without prior notice and without a vote, to the extent expressly so provided by the applicable certificate of designation relating to such series of Preferred Stock.

B.Except as otherwise required by law and subject to the rights of the holders of any series of Preferred Stock, special meetings of the stockholders of the Corporation for any purpose or purposes may be called at any time only by or at the direction of the Board of Directors or the Chair of the Board of Directors.

C.An annual meeting of stockholders for the election of directors to succeed those whose terms expire and for the transaction of such other business as may properly come before the meeting, shall be held at such place, if any, on such date, and at such time as shall be fixed exclusively by resolution of the Board of Directors or a duly authorized committee thereof.

ARTICLE IX

2. upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned (as defined below) at least 85% of the voting stock (as defined below) of the Corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned by (i) persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer, or

3. at or subsequent to such time, the business combination is approved by the Board of Directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66-2/3% of the outstanding voting stock of the Corporation which is not owned by the interested stockholder.

2. “associate,” when used to indicate a relationship with any person, means: (i) any corporation, partnership, unincorporated association or other entity of which such person is a director, officer or partner or is, directly or indirectly, the owner of 20% or more of any class of voting stock; (ii) any trust or other estate in which such person has at least a 20% beneficial interest or as to which such person serves as trustee or in a similar fiduciary capacity; and (iii) any relative or spouse of such person, or any relative of such spouse, who has the same residence as such person.

3. “business combination,” when used in reference to the Corporation and any interested stockholder of the Corporation, means:

(i) any merger or consolidation of the Corporation or any direct or indirect majority-owned subsidiary of the Corporation with (a) the interested stockholder, or (b) any other corporation, partnership, unincorporated association or other entity if the merger or consolidation is caused by the interested stockholder and as a result of such merger or consolidation Section (B) of this Article IX is not applicable to the surviving entity;

(ii) any sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of transactions), except proportionately as a stockholder of the Corporation, to or with the interested stockholder, whether as part of a dissolution or otherwise, of assets of the Corporation or of any direct or indirect majority-owned subsidiary of the Corporation which assets have an aggregate market value equal to 10% or more of either the aggregate market value of all the assets of the Corporation determined on a consolidated basis or the aggregate market value of all the outstanding stock of the Corporation;

(iii) any transaction which results in the issuance or transfer by the Corporation or by any direct or indirect majority-owned subsidiary of the Corporation of any stock of the Corporation or of such subsidiary to the interested stockholder, except: (a) pursuant to the exercise, exchange or conversion of securities exercisable for, exchangeable for or convertible into stock of the Corporation or any such subsidiary which securities were outstanding prior to the time that the interested stockholder became such; (b) pursuant to a merger under Section 251(g) of the DGCL; (c) pursuant to a dividend or distribution paid or made, or the exercise, exchange or conversion of securities exercisable for, exchangeable for or convertible into stock of the Corporation or any such subsidiary which security is distributed, pro rata to all holders of a class or series of stock of the Corporation subsequent to the time the interested stockholder became such; (d) pursuant to an exchange

(iv) any transaction involving the Corporation or any direct or indirect majority-owned subsidiary of the Corporation which has the effect, directly or indirectly, of increasing the proportionate share of the stock of any class or series, or securities convertible into the stock of any class or series, of the Corporation or of any such subsidiary which is owned by the interested stockholder, except as a result of immaterial changes due to fractional share adjustments or as a result of any purchase or redemption of any shares of stock not caused, directly or indirectly, by the interested stockholder; or

(v) any receipt by the interested stockholder of the benefit, directly or indirectly (except proportionately as a stockholder of the Corporation), of any loans, advances, guarantees, pledges, or other financial benefits (other than those expressly permitted in subsections (i)-(iv) above) provided by or through the Corporation or any direct or indirect majority-owned subsidiary.

such person shall be an interested stockholder if thereafter such person acquires additional shares of voting stock of the Corporation, except as a result of further corporate action not caused, directly or indirectly, by such person. For the purpose of determining whether a person is an interested stockholder, the voting stock of the Corporation deemed to be outstanding shall include stock deemed to be owned by the person through application of the definition of “owner” below but shall not include any other unissued stock of the Corporation which may be issuable pursuant to any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or otherwise.

6. “owner,” including the terms “own” and “owned,” when used with respect to any stock, means a person that individually or with or through any of its affiliates or associates:

(iii) has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting (except voting pursuant to a revocable proxy or consent as described in item (b) of subsection (ii) above), or disposing of such stock with any other person that beneficially owns, or whose affiliates or associates beneficially own, directly or indirectly, such stock.
