(a) Voting. Each holder of Common Stock, as such, shall be entitled to one vote for each share of Common Stock held of record by such holder on all matters on which stockholders generally are entitled to vote; provided, however, that, except as otherwise required by applicable law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate of Incorporation, including any certificate of designations relating to any series of Preferred Stock (each hereinafter referred to as a “Preferred Stock Designation”), 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 Certificate of Incorporation (including any Preferred Stock Designation).

BOARD OF DIRECTORS

Section 5.1 Number. Subject to the rights of the holders of any outstanding series of Preferred Stock and subject to Section 5.3(c), the Board of Directors shall solely consist of such number of directors as shall be determined from time to time by resolution adopted by the affirmative vote of a majority of the total number of directors then authorized.

Section 5.2 Classification; Designation; Nomination; Vacancies.

(a) Except as may be otherwise provided with respect to directors elected by the holders of any series of Preferred Stock provided for or fixed pursuant to the provisions of Article IV (including any Preferred Stock Designation (the “Preferred Stock Directors”)), the Board of Directors shall be divided into three classes, designated Class I, Class II and Class III. Class I directors shall initially serve until the Corporation’s first annual meeting of stockholders following the effectiveness of this Section 5.2; Class II directors shall initially serve until the Corporation’s second annual meeting of stockholders following the effectiveness of this Section 5.2; and Class III directors shall initially serve until the Corporation’s third annual meeting of stockholders following the effectiveness of this Section 5.2. Upon the expiration of the initial term of each class of directors set forth in the preceding sentence of this Section 5.2(a), respectively, directors of such class shall be elected to hold office for a three-year term and until the election and qualification of their respective successors in office or until any such director’s earlier death, resignation, removal (in accordance with this Certificate of Incorporation), retirement or disqualification. In the case of any increase or decrease, from time to time, in the number of directors (other than Preferred Stock Directors), the number of directors in each class shall be fixed solely by the Board of Directors (as determined solely by the Board of Directors); provided, further, that the Board of Directors shall not change the class designation of the THG Designees (as defined below) without the prior written approval of the THG Stockholders (as defined below). Subject to the immediately preceding sentence and Section 5.2(c), the Board of Directors shall have the exclusive power to fix the number of directors in each class and is authorized to assign members of the Board of Directors already in office to Class I, Class II or Class III.

(b) Subject to the rights of the holders of any outstanding series of Preferred Stock and subject to Section 5.2(c) and Section 5.2(e), unless otherwise required by applicable law, newly created directorships resulting from any increase in the authorized number of directors and any vacancies in the Board of Directors resulting from death, resignation, retirement, disqualification, removal (in accordance with this Certificate of Incorporation) or other cause shall be filled solely by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Board of Directors, or by the sole remaining director. Any director so chosen shall hold office until the next election of the class for which such director shall have been chosen and until his or her successor shall have been duly elected and qualified or until any such director’s earlier death, resignation, removal (in accordance with this Certificate of Incorporation), retirement or disqualification. No decrease in the authorized number of directors shall shorten the term of any incumbent director.

3

(c) In connection with the election of directors at each annual or special meeting of stockholders of the Corporation at which directors are to be elected, the THG Stockholders shall have the right, but not the obligation, to designate for nomination by the Corporation to the Board of Directors a number of designees equal to (in no case less than zero): (i) two directors so long as the THG Stockholders and their respective Affiliates collectively beneficially own 16.7% or more of the outstanding shares of Equity Securities (within the meaning of clause (i) of the definition of Equity Securities); and (ii) one director in the event that the THG Stockholders and their respective Affiliates collectively beneficially own less than 16.7% but more than 5% of the outstanding shares of Equity Securities (within the meaning of clause (i) of the definition Equity Securities), in each case of clause (i) and (ii), the directors to be nominated at such meeting shall be reduced by the number of THG Designees serving on the Board of Directors at such time who are not members of the class subject to election at such meeting of stockholders of the Corporation; provided, that the THG Stockholders shall permanently, and despite any later increase in their beneficial ownership, no longer be entitled to designate a director nominee at such time as the THG Stockholders and their respective Affiliates collectively beneficially own Common Stock representing less than 5% of the outstanding shares of Equity Securities (within the meaning of clause (i) of the definition of Equity Securities).

(d) With respect to any annual or special meeting of stockholders of the Corporation at which directors are to be elected, to the extent that the THG Stockholders have the right to designate a THG Designee pursuant to Section 5.2(c) at such annual or special meeting and subject to the laws of the State of Delaware (including with respect to fiduciary duties under Delaware law), each THG Designee (i) will be nominated and recommended by the Board of Directors to be elected as a director at such annual or special meeting of stockholders and included in the Corporation’s slate of nominees to be elected or appointed to the Board of Directors at such annual or special meeting of stockholders, (ii) will be recommended by the Board of Directors to the stockholders of the Corporation for a vote in favor of any such THG Designee, (iii) will be included in any proxy or consent solicitation statement of the Corporation or the Board of Directors in favor of any nominees for election or appointment to the Board of Directors and (iv) without limiting the foregoing, will receive the Corporation’s best efforts to cause such nominees who are THG Designees to be elected to the Board of Directors, including the Corporation providing at least as high a level of support for the election of such nominees as it provides to any other individual standing for election as a director.

(e) For so long as the THG Stockholders have the right to designate a THG Designee pursuant to Section 5.2(c), in the event that a vacancy is created at any time by the death, resignation, removal (in accordance with this Certificate of Incorporation), retirement or disqualification of any member of the Board of Directors designated by the THG Stockholders pursuant to Section 5.2(c), the vacancy so created shall be filled solely with a designee of the THG Stockholders (subject to the laws of the State of Delaware (including with respect to fiduciary duties under Delaware law)), and may not be filled with any other Person.

4

(f) In the event that the THG Stockholders shall cease to have the right to designate one or more director(s) pursuant to Section 5.2(c), the THG Designee(s) selected by the THG Stockholders shall continue to serve until his or her term expires at the next applicable annual meeting of stockholders of the Corporation or until his earlier death, resignation, removal, retirement or disqualification. In the event such THG Designee resigns, is removed or is not renominated for election (due to THG Stockholder ceasing to have the right to designate such THG Designee) in accordance with this Section 5.2(f), the directors remaining in office shall be entitled to decrease the size of the Board of Directors to eliminate such vacancy and no consent under Section 5.3(c)(ii) shall be required in connection with such decrease.

(g) Any director, or the entire Board of Directors (other than any Preferred Stock Director), may be removed from office at any time, but only for cause and only by the affirmative vote of at least 66²/₃% of the voting power of the stock outstanding and entitled to vote on the election of directors, voting together as a single class. Notwithstanding the foregoing, whenever the holders of any class or series are entitled to elect one or more directors by this Certificate of Incorporation (including any Preferred Stock Designation), with respect to the removal without cause of a director or directors so elected, the vote of the holders of the outstanding shares of that class or series, and not the vote of the outstanding shares as a whole, shall apply.

(h) During any period when the holders of any series of Preferred Stock have the right to elect additional directors as provided for or fixed pursuant to the provisions of Article IV (including any Preferred Stock Designation), and 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 be increased by such number of directors that the holders of any series of Preferred Stock have a right to elect, 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 Preferred Stock Director shall serve until such Preferred Stock 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 his or her earlier death, resignation, removal, retirement or disqualification. Except as otherwise provided for or fixed pursuant to the provisions of Article IV (including any Preferred Stock Designation), whenever the holders of any series of Preferred Stock having such right to elect additional directors cease to have or are otherwise divested of such right pursuant to said provisions, the terms of office of all such Preferred Stock Directors elected by the holders of such Preferred Stock, or elected to fill any vacancies resulting from the death, resignation, removal, retirement or disqualification of such additional directors, shall forthwith terminate (in which case each such Preferred Stock Director shall cease to be qualified as a director and shall cease to be a director) and the total authorized number of directors of the Corporation shall be automatically reduced accordingly.

Section 5.3 Powers.

(a) Except as otherwise required by the DGCL or as provided in this Certificate of Incorporation (including any Preferred Stock Designation, Section 5.2 and this Section 5.3) the business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors.

5

(b) Except as required by applicable law, for so long as the THG Stockholders and their respective Affiliates collectively beneficially own 15% or more of the outstanding shares of Equity Securities (within the meaning of clause (i) of the definition Equity Securities), the attendance of at least one THG Designee shall be required to constitute a quorum of the Board of Directors (or any committee of the Board of Directors on which a THG Designee serves) for the transaction of business with respect to such action or decision unless each THG Designee provides notice in writing or by electronic transmission to the remaining members of the Board of Directors, the Chairman of the Board of Directors or the Secretary of the Corporation waiving his or her right to be included in the quorum at such meeting; provided, however, that this Section 5.3(b) shall not apply to any Board of Directors meeting or committee meeting necessary to address any catastrophe or other similar emergency condition for the Corporation or in the case of any other emergency (as defined in Section 110 of the DGCL). Notwithstanding the foregoing, if there is less than a quorum at any meeting of the Board of Directors (or any committee thereof on which any of the THG Designees serves), a majority of the directors of the Corporation present may adjourn the meeting to a time no earlier than five business days after written notice of such adjournment has been given to each director of the Corporation not then in attendance. If a THG Designee is not present at the next meeting following an adjournment, then the presence of a number of directors of the Corporation exceeding 50% of the entire Board of Directors (or exceeding 50% of the entire committee, as applicable) entitled to vote shall constitute a quorum for the next meeting.

(c) Until the earlier of (i) the THG Stockholders and their respective Affiliates first ceasing to collectively beneficially own at least 5% of the outstanding shares of Equity Securities (within the meaning of clause (i) of the definition Equities Securities), (ii) July 10, 2027 and (iii) the termination of the Stockholders’ Agreement (as defined below), the following actions by the Corporation or any of its subsidiaries shall require the approval of the THG Stockholders, in addition to any approval by the stockholders of the Corporation or by the Board of Directors (or by the required governing body of any subsidiary of the Corporation as required by such subsidiary’s organizational documents) required by applicable law, this Certificate of Incorporation or the Bylaws of the Corporation (as amended and/or restated from time to time in accordance with the terms thereof and Section 10.2, the “Bylaws”):

(i) any amendment, modification or restatement of this Certificate of Incorporation or the Bylaws or the organizational documents of any subsidiary of the Corporation that is a “significant subsidiary” as defined in Rule 1-02 of Regulation S-X under the Exchange Act (as defined below);

(ii) any increase or decrease in the size of the Board of Directors;

(iii) terminating the employment of the Chief Executive Officer of the Corporation or hiring a new Chief Executive Officer of the Corporation, or removing the Chairperson of the Board of Directors or appointing a new Chairperson of the Board of Directors; and

(iv) initiating a voluntary liquidation, dissolution, receivership, bankruptcy or other insolvency proceeding involving the Corporation or any subsidiary of the Corporation that is a “significant subsidiary” as defined in Rule 1-02 of Regulation S-X under the Exchange Act.

6

(d) For so long as the THG Stockholders have the right to designate a THG Designee pursuant to Section 5.2(c) and to the fullest extent permitted by applicable law (including with respect to fiduciary duties under Delaware law), each committee of the Board of Directors shall include at least one THG Designee; provided that the ability of any THG Designee to serve on a committee shall be subject to the Corporation’s obligation to comply with any applicable independence requirements of The Nasdaq Stock Market LLC (or such other securities exchange or interdealer quotation system on which shares of Common Stock are then listed or quoted), the Securities and Exchange Commission and state law (including with respect to fiduciary duties under Delaware law) as determined in good faith by the Board of Directors.

The Board of Directors may postpone, reschedule or cancel any annual meeting of stockholders previously scheduled by the Board of Directors.

Notwithstanding the foregoing, 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 Preferred Stock Designation related to such series of Preferred Stock.

(i) any merger or consolidation of the Corporation or any direct or indirect majority-owned subsidiary of the Corporation (A) with the interested stockholder, or (B) with 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 this Article VIII 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 offer by the Corporation to purchase stock made on the same terms to all holders of said stock; or (E) any issuance or transfer of stock by the Corporation; provided, however, that in no case under items (C) through (E) of this subsection (iii) shall there be an increase in the interested stockholder’s proportionate share of the stock of any class or series of the Corporation or of the voting stock of the Corporation (except as a result of immaterial changes due to fractional share adjustments);

(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) through (iv) above) provided by or through the Corporation or any direct or indirect majority-owned subsidiary.

(d) “control,” including the terms “controlling,” “controlled by” and “under common control with,” means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a person, whether through the ownership of voting stock, by contract, or otherwise. A person who is the owner of 20% or more of the outstanding voting stock of a corporation, partnership, unincorporated association or other entity shall be presumed to have control of such entity, in the absence of proof by a preponderance of the evidence to the contrary. Notwithstanding the foregoing, a presumption of control shall not apply where such person holds voting stock, in good faith and not for the purpose of circumventing this Article VIII, as an agent, bank, broker, nominee, custodian or trustee for one or more owners who do not individually or as a group (as such term is used in Rule 13d-5 under the Exchange Act, as such Rule is in effect as of the date of this Certificate of Incorporation) have control of such entity.

(e) “interested stockholder” means any person (other than the Corporation or any direct or indirect majority-owned subsidiary of the Corporation) that either (i) is the owner of 15% or more of the outstanding voting stock of the Corporation, or (ii) is an affiliate or associate of the Corporation and was the owner of 15% or more of the outstanding voting stock of the Corporation at any time within the three-year period immediately prior to the date on which it is sought to be determined whether such person is an interested stockholder; and the affiliates and associates of such person; provided, however, that the term “interested stockholder” shall not include (A) any Principal Holder or Principal Holder Direct Transferee, (B) a stockholder that becomes an interested stockholder inadvertently and (x) as soon as practicable divests itself of ownership of sufficient shares so that such stockholder ceases to be an interested stockholder and (y) would not, at any time within the three-year period immediately prior to a business combination between the Corporation and such stockholder, have been an interested stockholder but for the inadvertent acquisition of ownership or (C) any person whose ownership of shares in excess of the 15% limitation set forth herein is the result of any action taken solely by the Corporation; provided, however, that such person specified in this clause (C) 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. For the avoidance of doubt, for purposes of this Article VIII, the Board of Directors, in its sole discretion, shall determine whether a stockholder became an interested stockholder inadvertently.

10

pursuant to a tender or exchange offer made by such person or any of such person’s affiliates or associates until such tendered stock is accepted for purchase or exchange; or (B) the right to vote such stock pursuant to any agreement, arrangement or understanding; provided, however, that a person shall not be deemed the owner of any stock because of such person’s right to vote such stock if the agreement, arrangement or understanding to vote such stock arises solely from a revocable proxy or consent given in response to a proxy or consent solicitation made to 10 or more persons; or

(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 clause (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.

(g) “Principal Holder Direct Transferee” means any person that acquires (other than in a registered public offering), directly from one or more of the Principal Holders, beneficial ownership of 15% or more of the then-outstanding voting stock of the Corporation.

(h) “Principal Holders” means (A) the THG Investor and its current and future affiliates (so long as any such respective affiliate remains an affiliate), (B) its and their related trusts, trustees and family members, (C) its and their respective successors and assigns and (D) any “group” of which any such person referred to in the foregoing clauses (A) through (C) is part under Rule 13d-5 of the Exchange Act; provided, however, that the term “Principal Holders” shall not include the Corporation or any of the Corporation’s direct or indirect subsidiaries.

(i) “stock” means, with respect to any corporation, capital stock and, with respect to any other entity, any equity interest.

(j) “voting stock” means stock of any class or series entitled to vote generally in the election of directors and, with respect to any entity that is not a corporation, any equity interest entitled to vote generally in the election of the governing body of such entity. Every reference in this Article VIII to a percentage or proportion of voting stock shall refer to such percentage or other proportion of the votes of such voting stock.

Section 11.2 Renunciation of Certain Corporate Opportunities; No Duty to Refrain. To the fullest extent permitted by applicable law, the Corporation hereby renounces any interest or expectancy in, or right to be offered an opportunity to participate in, any business opportunity which may be a corporate opportunity for (a) the THG Investor or any of its Affiliates or (b) any Non-Employee Director or his or her Affiliates (such Persons (as defined below) identified in (a) and (b) above being referred to, collectively, as “Identified Persons” and, individually, as an “Identified Person”) and the Corporation or any of its Affiliates. To the fullest extent permitted by applicable law, none of the Identified Persons shall have any duty to refrain from directly or indirectly (i) engaging in the same or similar business activities or lines of business in which the Corporation or any of its Affiliates now engages or proposes to engage or (ii) otherwise competing with the Corporation or any of its Affiliates, and, to the fullest extent permitted by applicable law, no Identified Person shall be liable to the Corporation or its stockholders or to any Affiliate of the Corporation for breach of any fiduciary duty solely by reason of the fact that such Identified Person engages in any such activities. In the event that any Identified Person acquires knowledge of a potential transaction or other business opportunity which may be a corporate opportunity for itself, herself or himself and the Corporation or any of its Affiliates, such Identified Person shall, to the fullest extent permitted by applicable law, have no duty to communicate or offer such transaction or other business opportunity to the Corporation or any of its Affiliates and, to the fullest extent permitted by applicable law, shall not be liable to the Corporation or its stockholders or to any Affiliate of the Corporation for breach of any fiduciary duty as a stockholder, director or officer of the Corporation solely by reason of the fact that such Identified Person pursues or acquires such corporate opportunity for itself, herself or himself, or offers or directs such corporate opportunity to another Person. Notwithstanding the foregoing and anything in this Section 11.2 to the contrary, the Corporation does not renounce its interest in any corporate opportunity offered to any Non-Employee Director if such opportunity is expressly offered in writing to such person solely in his or her capacity as a director or officer of the Corporation, and the provisions of Section 11.1 shall not apply to any such corporate opportunity.

Section 11.3 Opportunities Not Deemed Corporate Opportunities. In addition to and notwithstanding the foregoing provisions of this Article XI, a corporate opportunity shall not be deemed to be a potential corporate opportunity for the Corporation if it is a business opportunity that (a) the Corporation is neither financially or legally able, nor contractually permitted, to undertake, (b) from its nature, is not in the line of the Corporation’s business or is of no practical advantage to the Corporation or (c) is one in which the Corporation has no interest or reasonable expectancy.

Section 11.4 Notice and Consent. To the fullest extent permitted by applicable law, any Person purchasing or otherwise acquiring or holding any interest in any shares of capital stock of the Corporation shall be deemed to have notice of and to have consented to the provisions of this Article XI.

To the fullest extent permitted by the DGCL as the same exists or as may hereafter be amended, no director or officer of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, as applicable. All references in this Article XII to a director shall also be deemed to refer to such other person or persons, if any, who, pursuant to a provision set forth in this Certificate of Incorporation in accordance with Section 141(a) of the DGCL, exercise or perform any of the powers or duties otherwise conferred or imposed upon the Board of Directors by the DGCL.

Section 12.2 Amendment or Repeal.

Section 13.1 Forum. Unless the Corporation, in writing, selects or consents to the selection of an alternative forum: (a) the sole and exclusive forum for any complaint asserting any internal corporate claims (as defined below), to the fullest extent permitted by applicable law, and subject to applicable jurisdictional requirements, shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have, or declines to accept, jurisdiction, another state court or a federal court located within the State of Delaware); and (b) the sole and exclusive forum for any complaint asserting a cause of action arising under the Securities Act, to the fullest extent permitted by applicable law, shall be the federal district courts of the United States of America. For purposes of this Article XIII, “internal corporate claims” means claims, including claims in the right of the Corporation that are based upon a violation of a duty by a current or former director, officer, employee or stockholder in such capacity, or as to which the DGCL confers jurisdiction upon the Court of Chancery. Any person or entity purchasing or otherwise acquiring or holding any interest in shares of stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article XIII.

Section 13.2 Enforceability. If any provision of this Certificate of Incorporation shall be held to be invalid, illegal or unenforceable as applied to any person or entity or circumstance for any reason whatsoever, then, to the fullest extent permitted by applicable law, the validity, legality and enforceability of such provision in any other circumstance and of the remaining provisions of this Certificate of Incorporation (including each portion of any sentence of this Article XIII containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) and the application of such provision to other persons or entities or circumstances shall not in any way be affected or impaired thereby.
