ARTICLE III

The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware (the “DGCL”) as it now exists or may hereafter be amended and supplemented.

The Corporation is authorized to issue three classes of stock to be designated, respectively, “Class A Common Stock”, Class B Common Stock and “Preferred Stock.” The total number of shares of capital stock which the Corporation shall have authority to issue is 310 million (310,000,000). The total number of shares of all classes of capital stock that the Corporation is authorized to issue is (i) 250 million (250,000,000) shares of Class A common stock, having a par value of $0.001 per share (the “Class A Common Stock”), (ii) 50 million (50,000,000) shares of Class B common stock, having a par value of $0.001 per share (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”), and (iii) 10 million (10,000,000) shares of preferred stock, having a par value of $0.001 per share (the “Preferred Stock”) as of the Effective Time (as defined herein) of this Amended and Restated Certificate of Incorporation (the “Restated Certificate”).

Effective at the Effective Time, each share of common stock of the Corporation issued and outstanding immediately prior to the Effective Time (the “Original Capital Stock”) shall be automatically reclassified as one (1) outstanding share of Class A Common Stock (the “Reclassification” and, such shares, the “Reclassified Shares”) without any action on the part of the Corporation or the holder of such shares. The Reclassified Shares shall be uncertificated and any stock certificate that, immediately prior to the Effective Time, represented shares of Original Capital Stock shall upon surrender to the Corporation be cancelled.

ARTICLE V

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.

1.    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.

2.    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 and shall be entitled to one (1) vote for each share of Common Stock held of record by such holder as of the record date for determining stockholders entitled to vote on such matter. Except as otherwise required in this Restated Certificate or by applicable law, the holders of Common Stock shall vote together as a single class on all matters (or, if any holders of Preferred Stock are entitled to vote together with the holders of Common Stock, as a single class with such holders of Preferred Stock). Except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Restated Certificate (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 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 as a separate class pursuant to this Restated Certificate (including any Certificate of Designation) or pursuant to the DGCL.

Subject to the rights of any holders of any outstanding series of Preferred Stock, the number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote thereon, irrespective of the provisions of Section 242(b)(2) of the DGCL.

3.    Dividends. Subject to applicable law and the rights and preferences of any holders of any outstanding series of Preferred Stock or any class or series of capital stock of the Corporation having a preference over or the right to participate with the Class A Common Stock with respect to the payment of dividends, dividends may be declared and paid on the Class A Common Stock out of the assets of the Corporation that are by law available therefor, at such times and in such amounts as the Board of Directors in its discretion shall determine. Dividends shall not be declared or paid on the Class B Common Stock.

4.    Liquidation. 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 capital stock of the Corporation having a preference over or the right to participate with the Class A Common Stock with respect to amounts payable upon a voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation, in the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation, after payment or

3

provision for payment of the debts and other liabilities of the Corporation and of the preferential and other amounts, if any, to which the holders of Preferred Stock or any class or series of capital stock of the Corporation having a preference over such amounts shall be entitled, the holders of all outstanding shares of Class A Common Stock shall be entitled to receive the remaining assets of the Corporation available for distribution ratably in proportion to the number of shares held by each such stockholder. Without limiting the rights of the holders of Class B Common Stock to have their Common Units (as defined below) redeemed or exchanged in accordance with Article XI of the LLC Agreement (as defined below), the holders of shares of Class B Common Stock shall be entitled to receive $0.001 per share in any liquidation, dissolution or winding up on a pari passu basis with the holders of Class A Common Stock, and upon receiving such amount, the holders of shares of Class B Common Stock, as such, shall not be entitled to receive any other assets or funds of the Corporation. A consolidation, reorganization or merger of the Corporation with any other person or persons, or a sale of all or substantially all of the assets of the Corporation, shall not be considered to be a dissolution, liquidation or winding up of the Corporation within the meaning of this Article V(A)(4).

5.    Additional Shares. From and after the Effective Time, additional shares of Class B Common Stock may be issued only to, and registered in the name of, the Existing Owner (as defined below), its respective successors and assigns as well as its respective transferees permitted in accordance with Article V(A)(6) (including all subsequent successors, assigns and permitted transferees) (the Existing Owner together with such persons, collectively, “Permitted Class B Owners”) in accordance with Article VI and the aggregate number of shares of Class B Common Stock following any such issuance registered in the name of each such Permitted Class B Owner must be equal to the aggregate number of Common Units (as defined below) held of record by such Permitted Class B Owner under the LLC Agreement (as defined below). As used in this Restated Certificate (i) “Existing Owner” means Smith & Nephew, Inc., (ii) “Common Unit” means a membership interest in Bioventus LLC, a Delaware limited liability company, or any successor entities thereto (the “LLC”), to be authorized and issued under its Second Amended and Restated Limited Liability Company Agreement, as such agreement may be further amended, restated, amended and restated, supplemented or otherwise modified from time to time (the “LLC Agreement”), and constituting a “Common Unit” as defined in the LLC Agreement.

6.    Transfers. A holder of Class B Common Stock may surrender shares of Class B Common Stock to the Corporation for no consideration at any time. Following the surrender of any shares of Class B Common Stock to the Corporation, the Corporation will take all actions necessary to retire such shares and such shares shall not be re-issued by the Corporation. “Transfer” (and, with a correlative meaning, “transferring”) means any sale, transfer, assignment, redemption, pledge, encumbrance or other disposition of (whether directly or indirectly, whether with or without consideration and whether voluntarily or involuntarily or by operation of law) (i) any interest (legal or beneficial) in any shares of capital stock of the Corporation or (ii) any equity or other interest (legal or beneficial) in any stockholder if substantially all of the assets of such stockholder consist solely of shares of capital stock of the Corporation.

A holder of Class B Common Stock may transfer shares of Class B Common Stock to any transferee (other than the Corporation) only if, and only to the extent permitted by the LLC

4

Agreement, such holder also simultaneously transfers an equal number of such holder’s Common Units (as such numbers may be adjusted to reflect equitably any stock split, subdivision, combination or similar change with respect to the Class B Common Stock or Common Units) to such transferee in compliance with the LLC Agreement. The transfer restrictions described in this Article V(A)(6) are referred to as the “Restrictions.”

Any purported transfer of shares of Class B Common Stock in violation of the Restrictions shall be null and void ab initio. If, notwithstanding the Restrictions, a person shall, voluntarily or involuntarily, purportedly become or attempt to become, the purported owner (“Purported Owner”) of shares of Class B Common Stock in violation of the Restrictions, then the Purported Owner shall not obtain any rights in and to such shares of Class B Common Stock (the “Restricted Shares”), and the purported transfer of the Restricted Shares to the Purported Owner shall not be recognized by the Corporation or the Corporation’s transfer agent (the “Transfer Agent”).

Upon a determination by the Board of Directors that a person has attempted or may attempt to transfer or to acquire Restricted Shares in violation of the Restrictions, the Board of Directors may take such action as it deems advisable to refuse to give effect to such transfer or acquisition on the books and records of the Corporation, including without limitation to cause the Transfer Agent to record the Purported Owner’s transferor as the record owner of the Restricted Shares, and to institute proceedings to enjoin or rescind any such transfer or acquisition.

The Board of Directors may, to the extent permitted by law, from time to time establish, modify, amend or rescind, by bylaw or otherwise, regulations and procedures that are consistent with the provisions of this Article V(A)(6) for determining whether any transfer or acquisition of shares of Class B Common Stock would violate the Restrictions and for the orderly application, administration and implementation of the provisions of this Article V(A)(6). Any such procedures and regulations shall be kept on file with the Secretary of the Corporation and with its Transfer Agent and shall be made available for inspection by any prospective transferee and, upon written request, shall be mailed to holders of shares of Class B Common Stock.

The Board of Directors shall have all powers necessary to implement the Restrictions, including without limitation the power to prohibit the transfer of any shares of Class B Common Stock in violation thereof. As used in this Article V(A)(6), the term “transfer,” as it relates to the shares of Class B Common Stock, shall not be deemed to include any bona fide pledge or collateralization by a holder thereof to a financial institution in connection with any bona fide loan or debt transaction, but such term shall include any foreclosure on such shares by such financial institution following or in connection with any such pledge or collateralization.

7.    Redemption and Cancellation. To the extent that any Permitted Class B Owner exercises its right pursuant to the LLC Agreement to have its Common Units redeemed by the LLC in accordance with the LLC Agreement, then simultaneous with the payment of cash or Class A Common Stock consideration to such Permitted Class B Owner by the LLC (in the case of a redemption) or the Corporation (in the case of an election by the Corporation pursuant to the LLC Agreement to effect a direct exchange with such Permitted Class B Owner) in accordance with the LLC Agreement, the Corporation shall cancel for no consideration a number

5

of shares of Class B Common Stock registered in the name of the redeeming or exchanging Permitted Class B Owner equal to the number of Common Units held by such Permitted Class B Owner that are redeemed or exchanged in such redemption or exchange transaction. Notwithstanding the Restrictions, (i) in the event that any outstanding share of Class B Common Stock shall cease to be held by a registered holder of Common Units, such share of Class B Common Stock shall automatically and without further action on the part of the Corporation or any holder of Class B Common Stock be cancelled for no consideration, and the Corporation will take all actions necessary to retire such share and such share shall not be re-issued by the Corporation, (ii) in the event that any registered holder of the Class B Common Stock no longer holds an interest in the Common Units, the shares of Class B Common Stock registered in the name of such holder shall automatically and without further action on the part of the Corporation or any holder of Class B Common Stock be cancelled for no consideration, and the Corporation will take all actions necessary to retire such shares and such shares shall not be re-issued by the Corporation and (iii) in the event that no Permitted Class B Owner owns any Common Units that are redeemable pursuant to the LLC Agreement, then all shares of Class B Common Stock will be cancelled for no consideration, and the Corporation will take all actions necessary to retire such shares and such shares shall not be re-issued by the Corporation.

8.    Legends. All certificates or book entries representing shares of Class B Common Stock, as the case may be, shall bear a legend substantially in the following form (or in such other form as the Board of Directors may determine):

THE SECURITIES REPRESENTED BY THIS [CERTIFICATE][BOOK ENTRY] ARE SUBJECT TO THE RESTRICTIONS (INCLUDING RESTRICTIONS ON TRANSFER AND OWNERSHIP) SET FORTH IN THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION (A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE CORPORATION AND SHALL BE PROVIDED FREE OF CHARGE TO ANY STOCKHOLDER MAKING A REQUEST THEREFOR).

To the extent shares of Class B Common Stock are uncertificated, the Corporation shall give notice of the restrictions set forth herein in accordance with the DGCL.

9.    Fractional Shares. The Class B Common Stock may be issued and transferred in fractions of a share which shall entitle the holder to exercise voting rights and to have the benefit of all other rights of holders of Class B Common Stock. Subject to the Restrictions, holders of shares of Class B Common Stock shall be entitled to transfer fractions thereof and the Corporation shall, and shall cause the Transfer Agent to, facilitate any such transfers, including by issuing certificates or making book entries representing any such fractional shares. For all purposes of this Amended and Restated Certificate of Incorporation (including, without limitation, Article V(A)(2), Article V(A)(4), Article V(A)(6), Article V(A)(7), this Article V(A)(9), Article VI(D) and Article VI(E) hereof), all references to the Class B Common Stock or any share thereof (whether in the singular or plural) shall be deemed to include references to any fraction of a share of Class B Common Stock.

B. PREFERRED STOCK

Shares of Preferred Stock may be issued from time to time in one or more series, each of such series to have such terms as stated or expressed herein and in the resolution or resolutions providing for the creation and issuance of such series adopted by the Board of Directors as hereinafter provided.

Authority is hereby expressly granted to the Board of Directors from time to time, subject to any limitations prescribed by law or that certain stockholders agreement, to be entered into by and among the Corporation, the LLC and the other persons party thereto (as it may be amended from time to time, the “Stockholders Agreement”), to issue the Preferred Stock in one or more series, and in connection with the creation of any such series, by adopting a resolution or resolutions providing for the issuance of the shares thereof and by filing a certificate of designation relating thereto in accordance with the DGCL (a “Certificate of Designation”), to determine and fix the number of shares of such series and such voting powers, full or limited, or no voting powers, and such designations, preferences and relative participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including without limitation thereof, dividend rights, conversion rights, redemption privileges and liquidation preferences, and to increase or decrease (but not below the number of shares of such series then outstanding) the number of shares of any series as shall be stated and expressed in such resolutions, all to the fullest extent now or hereafter permitted by the DGCL. In case the number of shares of any series shall be so decreased, the shares constituting such decrease shall resume the status which they had prior to the adoption of the resolution originally fixing the number of shares of such series. Without limiting the generality of the foregoing, the resolution or resolutions providing for the creation and issuance of any series of Preferred Stock may provide that such series shall be superior or rank equally or be junior to any other series of Preferred Stock to the extent permitted by law and this Restated Certificate (including any Certificate of Designation). Except as otherwise required by law, holders of any series of Preferred Stock shall be entitled only to such voting rights, if any, as shall expressly be granted thereto by this Restated Certificate (including any Certificate of Designation).

Subject to the rights of any holders of any outstanding series of Preferred Stock, the number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote thereon, irrespective of the provisions of Section 242(b)(2) of the DGCL.

ARTICLE VI

A.    The Corporation shall undertake all actions, including, without limitation, any subdivision (by any stock split, stock dividend, reclassification, recapitalization or similar event) or combination (by reverse stock split, reclassification, recapitalization or similar event), with respect to the shares of Class A Common Stock necessary to maintain at all times a one-to-one ratio between the number of Common Units owned by the Corporation and the number of outstanding shares of Class A Common Stock, disregarding, for purposes of maintaining the one-to-one ratio, (i) shares of Class A Common Stock issued pursuant to the Bioventus Phantom Profits Interest Plan (the “Bioventus Stock Plan”), the 2021 Incentive Award Plan and any other stock incentive plan adopted by the Corporation from time to time, that have not vested

7

thereunder, (ii) treasury stock, and (iii) Preferred Stock or other debt or equity securities (including without limitation warrants, options and rights) issued by the Corporation that are convertible or exercisable or exchangeable for Class A Common Stock (except to the extent the net proceeds from such other securities, including without limitation any exercise or purchase price payable upon conversion, exercise or exchange thereof, has been contributed by the Corporation to the equity capital of the LLC) (clauses (i), (ii) and (iii), collectively, the “Disregarded Shares”).

B.    The Corporation shall undertake all actions, including, without limitation, any subdivision (by any stock split, stock dividend, reclassification, recapitalization or similar event) or combination (by reverse stock split, reclassification, recapitalization or similar event), with respect to the shares of Class B Common Stock necessary to maintain at all times a one-to-one ratio between the number of Common Units owned by all Permitted Class B Owners and the number of outstanding shares of Class B Common Stock owned by all Permitted Class B Owners.

C.    The Corporation shall not undertake or authorize (i) any subdivision (by any stock split, stock dividend, reclassification, recapitalization or similar event) or combination (by reverse stock split, reclassification, recapitalization or similar event) of the Class A Common Stock that is not accompanied by an identical subdivision or combination of the Common Units to maintain at all times a one-to-one ratio between the number of Common Units owned by the Corporation and the number of outstanding shares of Class A Common Stock, disregarding, for purposes of maintaining such one-to-one ratio, the Disregarded Shares; or (ii) any subdivision (by any stock split, stock dividend, reclassification, recapitalization or similar event) or combination (by reverse stock split, reclassification, recapitalization or similar event) of the Class B Common Stock that is not accompanied by an identical subdivision or combination of the Common Units to maintain at all times, subject to the provisions of this Restated Certificate, a one-to-one ratio between the number of Common Units owned by the Permitted Class B Owners and the number of outstanding shares of Class B Common Stock, unless, in the case of clause (i) or (ii) of this Article VI(C), such action is necessary to maintain at all times both a one-to-one ratio between the number of Common Units owned by the Corporation and the number of outstanding shares of Class A Common Stock, disregarding, for purposes of maintaining such one-to-one ratio, the Disregarded Shares, and a one-to-one ratio between the number of Common Units owned by the Permitted Class B Owners and the number of outstanding shares of Class B Common Stock.

D.    The Corporation shall not issue, transfer or dispose of treasury stock or repurchase shares of Class A Common Stock unless in connection with any such issuance, transfer, disposition or repurchase the Corporation takes or authorizes all requisite action such that, after giving effect to all such issuances, transfers, dispositions or repurchases, the number of Common Units owned by the Corporation will equal on a one-for-one basis the number of outstanding shares of Class A Common Stock, disregarding, for purposes of maintaining the one-to-one ratio, the Disregarded Shares.

E.     The Corporation shall not issue, transfer or dispose of treasury stock or repurchase or redeem shares of Preferred Stock unless in connection with any such issuance, transfer,

8

disposition, repurchase or redemption the Corporation takes all requisite action such that, after giving effect to all such issuances, transfers, dispositions, repurchases or redemptions, the Corporation holds (in the case of any issuance, transfer or disposition) or ceases to hold (in the case of any repurchase or redemption) equity interests in the LLC which (in the good faith determination by the Board of Directors) are in the aggregate substantially equivalent in all respects to the outstanding Preferred Stock so issued, transferred, disposed, repurchased or redeemed.

F.    The Corporation shall not consolidate, merge, combine or consummate any other transaction (other than an action or transaction for which an adjustment is provided in one of the preceding paragraphs of this Article VI or in Article V) in which shares of Class A Common Stock are exchanged for or converted into other stock or securities, or the right to receive cash and/or any other property, unless in connection with any such consolidation, merger, combination or other transaction each Common Unit shall be entitled to be exchanged for or converted into (without duplication of any corresponding share of Class A Common Stock which the Corporation may elect to issue upon a redemption of such Common Unit by the holder thereof) the same kind and amount of stock or securities, cash and/or any other property, as the case may be, into which or for which each share of Class A Common Stock is exchanged or converted, in each case to maintain at all times a one-to-one ratio between (x) the stock or securities, or rights to receive cash and/or any other property issuable in such transaction in exchange for or conversion of one share of Class A Common Stock and (y) the stock or securities, or rights to receive cash and/or any other property issuable in such transaction in exchange for or conversion of one Common Unit. The foregoing provisions of this Article VI(F) shall not apply to any action or transaction (including any consolidation, merger or combination) approved by the holders of a majority of the voting power of the Class A Common Stock and Class B Common Stock, each voting as a separate class.

ARTICLE VII

The Corporation shall at all times reserve and keep available out of its authorized but unissued shares or other securities the number of shares or securities required to satisfy its obligations in connection with any exchange pursuant to the LLC Agreement; provided that nothing contained herein shall be construed to preclude the Corporation from satisfying its obligations in respect of any such exchange by delivery of shares of Class A Common Stock which are held in the treasury of the Corporation. The Corporation covenants that all shares of Class A Common Stock issued upon any such exchange will, upon issuance, be validly issued, fully paid and non-assessable.

ARTICLE VIII

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

A.    Subject to the special rights of the holders of one or more outstanding series of Preferred Stock to elect directors (such directors, “Preferred Stock Directors”), the directors of the Corporation shall be divided into three classes, designated as Class I, Class II and Class III.

9

The initial Class I directors shall serve for a term expiring at the first annual meeting of the stockholders following the initial registration of the Class A Common Stock pursuant to the Securities Exchange Act of 1934, as amended; the initial Class II directors shall serve for a term expiring at the second annual meeting of the stockholders following such registration; and the initial Class III directors shall serve for a term expiring at the third annual meeting following such registration. At each annual meeting of stockholders of the Corporation beginning with the first annual meeting of stockholders following such registration, subject to any special rights of the holders of one or more outstanding series of Preferred Stock to elect Preferred Stock Directors, 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. 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. No decrease in the number of directors shall shorten the term of any incumbent director. Subject to the Stockholders Agreement, the Board of Directors is authorized to assign members of the Board of Directors already in office upon the effectiveness of this Restated Certificate to Class I, Class II and Class III.

B.    Except as otherwise expressly provided by the DGCL or this Restated Certificate, the business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. Subject to the Stockholders Agreement, the number of directors which shall constitute the whole Board of Directors shall be fixed exclusively by one or more resolutions adopted from time to time by a majority of the Whole Board. For purposes of this Restated Certificate, the term “Whole Board” shall mean the total number of authorized directors for the Board of Directors whether or not there exist any vacancies in previously authorized directorships.

C.    Subject to the special rights of the holders of one or more outstanding series of Preferred Stock to elect Preferred Stock Directors and subject to the Stockholders Agreement, the Board of Directors or any individual director may be removed from office at any time, but only for cause and only by the affirmative vote of the holders of at least two-thirds 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.

D.    Subject to the special rights of the holders of one or more outstanding series of Preferred Stock to elect Preferred Stock Directors and subject to the Stockholders Agreement, 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 exclusively 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 (other than any Preferred Stock Directors), and shall not be filled by the stockholders. Any director appointed in accordance with the preceding sentence shall hold office until the expiration of the term of the class to which such director shall have been appointed or until his or her earlier death, resignation, retirement, disqualification, or removal.

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

10

more such other series, to elect Preferred Stock Directors, the election, term of office, removal and other features of such directorships shall be governed by the terms of this Restated Certificate (including any Certificate of Designation). Notwithstanding anything to the contrary in this Article VIII, 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 Article VIII(B), 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 Bylaws of the Corporation (the “Bylaws”). In addition to any vote of the holders of any class or series of stock of the Corporation required by applicable law or by this Restated Certificate (including any Certificate of Designation in respect of one or more series of Preferred Stock) or the Bylaws, the adoption, amendment or repeal of the Bylaws by the stockholders of the Corporation shall require the affirmative vote of the holders of at least two-thirds 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, voting together as a single class.

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

ARTICLE IX

A.    Until such time the Corporation ceases to be a “controlled company” within the meaning of the corporate governance standards of The Nasdaq Global Market, as amended from time to time (the “Trigger Date”), any action required or permitted to be taken by the stockholders of the Corporation at any annual or special meeting of stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, are signed by the holders of outstanding 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 of stock of the Corporation entitled to vote thereon were present and voted and delivered to the Corporation in accordance with the DGCL; provided, however, that no action by stockholders may be taken by written consent in lieu of a meeting of stockholders unless such written consent and the taking of the action specified therein have been previously approved by the affirmative vote of Directors constituting a majority of the Whole Board and provided, further, 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

11

so provided by the applicable Certificate of Designation relating to such series of Preferred Stock. From and after the Trigger Date, any action required or permitted to be taken by the stockholders of the Corporation must be effected at an annual or special meeting of the stockholders and may not be effected by written consent in lieu of a meeting; 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.    Subject to the special rights of the holders of one or more series of Preferred Stock, special meetings of the stockholders may be called only by (a) the chairperson of the Board of Directors, (b) the Chief Executive Officer, (c) the President, (d) the Secretary or (e) a resolution adopted by the affirmative vote of Directors constituting a majority of the Whole Board.

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.

ARTICLE X

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 X, or the adoption of any provision of the Restated Certificate inconsistent with this Article X, 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 X 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 XI

The Corporation shall have the power to provide rights to indemnification and advancement of expenses to its current and former officers, directors, employees and agents and to any person who 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.

ARTICLE XII

To the fullest extent permitted by the laws of the State of Delaware, (a) the Corporation hereby renounces all interest and expectancy that it otherwise would be entitled to have in, and all rights to be offered an opportunity to participate in, any business opportunity that from time to time may be presented to (i) the Board of Directors or any director, (ii) any stockholder, officer or agent of the Corporation, or (iii) any affiliate of any person or entity identified in the

12

preceding clause (i) or (ii), but in each case excluding any such person in its capacity as an employee of the Corporation or its subsidiaries; (b) no holder of Class A Common Stock or Class B Common Stock and no director that is not an employee of the Corporation or its subsidiaries will have any duty to refrain from (i) engaging in a corporate opportunity in the same or similar lines of business in which the Corporation or its subsidiaries from time to time is engaged or proposes to engage or (ii) otherwise competing, directly or indirectly, with the Corporation or any of its subsidiaries; and (c) if any holder of Class A Common Stock or Class B Common Stock or any director that is not an employee of the Corporation or its subsidiaries acquires knowledge of a potential transaction or other business opportunity which may be a corporate opportunity both for such holder of Class A Common Stock or Class B Common Stock or such director or any of their respective affiliates, on the one hand, and for the Corporation or its subsidiaries, on the other hand, such holder of Class A Common Stock or Class B Common Stock or director shall have no duty to communicate or offer such transaction or business opportunity to the Corporation or its subsidiaries and such holder of Class A Common Stock or Class B Common Stock or director may take any and all such transactions or opportunities for itself or offer such transactions or opportunities to any other person or entity. The preceding sentence of this Article XII shall not apply to any potential transaction or business opportunity that is expressly offered to a director, who is not an employee of the Corporation or its subsidiaries, solely in his or her capacity as a director of the Corporation.

To the fullest extent permitted by the laws of the State of Delaware, no potential transaction or business opportunity may be deemed to be a potential corporate opportunity of the Corporation or its subsidiaries unless (a) the Corporation and its subsidiaries would be permitted to undertake such transaction or opportunity in accordance with this Restated Certificate, (b) the Corporation and its subsidiaries at such time have sufficient financial resources to undertake such transaction or opportunity and (c) such transaction or opportunity would be in the same or similar line of business in which the Corporation and its subsidiaries are then engaged or a line of business that is reasonably related to, or a reasonable extension of, such line of business.

No holder of Class A Common Stock or Class B Common Stock and no director will be liable to the Corporation or its subsidiaries or stockholders for breach of any duty (contractual or otherwise) by reason of any activities or omissions of the types referred to in this Article XII, except to the extent such actions or omissions are in breach of this Article XII.

ARTICLE XIII

Unless the Corporation consents in writing to the selection of an alternative forum, (a) 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) 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, other employee or stockholder 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 of the Corporation or this Restated Certificate (as either may be amended from time to time) or as to which the DGCL

13

confers jurisdiction on the Chancery Court or (iv) any action, suit or proceeding asserting a claim against the Corporation governed by the internal affairs doctrine; and (b) 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 of 1933, as amended. If any action the subject matter of which is within the scope of clause (a) 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 (x) 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 clause (a) of the immediately preceding sentence and (y) 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.

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 XIII. Notwithstanding the foregoing, the provisions of this Article XIII shall not apply to suits brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts of the United States have exclusive jurisdiction.

If any provision or provisions of this Article XIII shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever, (a) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Article XIII (including, without limitation, each portion of any paragraph 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) shall not in any way be affected or impaired thereby and (b) the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby.

14

to the fullest extent permitted by applicable law, the provisions of this Restated Certificate (including, without limitation, each such portion of any paragraph of this 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.

ARTICLE XV

A.    The effective time of this Restated Certificate shall be the date and time that this Restated Certificate is filed with the Secretary of State of the State of Delaware (the “Effective Time”).
