MEETINGS OF STOCKHOLDERS

Section 2.1 Annual Meeting. The annual meeting of the stockholders of the Corporation for the election of Directors and for the transaction of such other business as may properly come before the meeting shall be held at such place, if any, either within or without the State of Delaware, or by means of remote communication, and on such date and at such time as the Board of Directors may fix by resolution and as set forth in the notice of the meeting.

Section 2.2 Special Meetings. Special meetings of stockholders, unless otherwise prescribed by law, may be called at any time by the Chairman of the Board, by the Chief Executive Officer, by the President or by order of the Board of Directors. Special meetings of stockholders prescribed by law for the election of Directors shall be called by the Board of Directors, the Chairman of the Board, the Chief Executive Officer, the President, or the Secretary whenever required to do so pursuant to applicable law. Special meetings of stockholders shall be held on such date and at such time and at such place, if any, either within or without the State of Delaware, as shall be designated in the notice of meeting or by means of remote communication. Except as otherwise provided in Section 3.4 with respect to the nomination of Directors, only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the Corporation’s notice of meeting.

Section 2.3 List of Stockholders Entitled to Vote. The officer who has charge of the stock ledger of the Corporation shall prepare and make, or cause to be prepared and made, at least ten days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting based upon the record date for such meeting determined pursuant to Section 5.8 (provided, however, if the record date for determining the stockholders entitled to vote is less than ten days before the date of the meeting, the list shall reflect the stockholders entitled to vote as of the tenth day before the meeting date), arranged by any applicable voting groups and in alphabetical order, and showing the address of each stockholder and the number of shares of capital stock of the Corporation registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, for a period of at least ten days prior to the meeting: (a) on a reasonably accessible electronic network, provided that the information required to gain access to such list was provided with the notice of the meeting; or (b) during ordinary business hours, at the principal place of business of the Corporation. The Corporation shall not be required to include electronic mail addresses or other electronic contact information on such list. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. Such list shall presumptively determine the identity of the stockholders entitled to vote at the meeting and the number of shares held by each of them. Except as provided by applicable law, the stock ledger shall be the only evidence as to who are the stockholders entitled to examine the stock ledger and the list of stockholders entitled to vote at any meeting of stockholders or to vote in person or by proxy at any such meeting. Notwithstanding the foregoing, the Corporation may maintain and authorize examination of the list of stockholders in any manner expressly permitted by the Delaware General Corporation Law (“DGCL”) at the time.

Section 2.4 Notice of Meeting. Except as otherwise prescribed by law, a notice of each meeting of stockholders, in the form of a writing or electronic transmission, shall be given by the Corporation, not more than sixty (60) nor less than ten (10) days before the date of such meeting, to each stockholder entitled to vote thereat, which notice shall state the place, if any, date and time of the meeting, the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, the record date for determining the stockholders entitled to vote at the meeting, if such date is different from the record date for determining stockholders entitled to notice of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called. If mailed, such notice shall be deemed given when deposited in the United States mail, postage prepaid, directed to such stockholder at his or her address as the same appears on the records of the Corporation. Without limiting the manner by which notices of meetings otherwise may be given effectively to stockholders, any such notice may be given by electronic transmission in the manner provided in Section 232 of the DGCL.

Notice of any meeting need not be given to any stockholder who shall, either before or after the meeting, submit a waiver of notice or who shall attend such meeting, except when the stockholder attends for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Any stockholder so waiving notice of the meeting shall be bound by the proceedings of the meeting in all respects as if due notice thereof had been given.

An affidavit of the Secretary, an Assistant Secretary or the transfer agent or other agent of the Corporation that notice has been duly given shall be evidence of the facts stated therein.

Section 2.5 Adjourned Meetings and Notice Thereof. Any meeting of stockholders may be adjourned to another time or place (including an adjournment taken to address a technical failure to convene or continue a meeting using remote communication), and the Corporation may transact at any adjourned meeting any business which might have been transacted at the original meeting. Notice need not be given of the adjourned meeting if the time, place, if any, thereof, and the means of remote communication, if any, are (i) announced at the meeting at which the adjournment is taken, (ii) displayed, during the time scheduled for the meeting, on the same electronic network used to enable stockholders and proxy holders to participate in the meeting by means of remote communication, or (iii) set forth in the notice of meeting given in accordance with Section 222(a) of the DGCL; provided, however, that if (a) any adjournment or series of adjournments cause the original meeting to be adjourned for more than thirty (30) days after the date originally fixed therefor or (b) a new record date is fixed for stockholders entitled to vote at the adjourned meeting, notice shall be given to each stockholder of record entitled to vote at the adjourned meeting.

Section 2.6 Quorum. At any meeting of stockholders, except as otherwise expressly required by law or by the Certificate of Incorporation, the holders of record of at least a majority of the outstanding shares of capital stock entitled to vote or act at such meeting shall be present in person or represented by proxy in order to constitute a quorum for the transaction of any business. If, however, such quorum shall not be present in person or represented at any meeting of stockholders, the chair of the meeting or the stockholders entitled to vote thereat, present in person or represented by proxy, shall have the power, by the affirmative vote of a majority in voting power thereof, to adjourn the meeting from time to time, in the manner provided in Section 2.5, until a quorum shall be present or represented. At any such adjourned meeting at which there is a quorum present, any business may be transacted that might have been transacted at the meeting originally called. When a quorum is once present to organize a meeting, the quorum cannot be destroyed by the subsequent withdrawal or revocation of the proxy of any stockholder. Shares of capital stock owned by the Corporation or by another corporation, if a majority of the shares of such other corporation entitled to vote in the election of Directors is held by the Corporation, shall not be counted for quorum purposes or entitled to vote.

Section 2.7 Voting.

(a) General. At any meeting of stockholders, each stockholder holding, as of the record date, shares of capital stock entitled to be voted on any matter at such meeting shall have one vote on each such matter submitted to vote at such meeting for each such share of capital stock held by such stockholder, as of the record date, as shown by the list of stockholders entitled to vote at the meeting, unless the Certificate of Incorporation provides for more or less than one vote for any share, on any matter, in which case every reference in these Bylaws to a majority or other proportion of stock shall refer to such majority or other proportion of the votes of such stock.

(b) Proxies. Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for him or her by proxy, provided that no proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. Such authorization may be in a writing executed by the stockholder or his or her authorized officer, director, employee, or agent. To the extent permitted by law, a stockholder may authorize another person or persons to act for him or her as proxy by transmitting or authorizing the transmission of an electronic transmission to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization, or like agent duly authorized by the person who will be the holder of the proxy to receive such transmission, provided that the electronic transmission either sets forth or is submitted with information from which it can be determined that the electronic transmission was authorized by the stockholder. A copy, facsimile transmission, or other reliable reproduction of the proxy authorized by this Section 2.7(b) may be substituted for or used in lieu of the original writing or electronic transmission for any and all purposes for which the original writing or electronic transmission could be used, provided that such copy, facsimile transmission, or other reproduction shall be a complete reproduction of the entire original writing or electronic transmission. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only so long as, it is coupled with an interest, whether in the stock itself or in the Corporation generally, sufficient in law to support an irrevocable power. A stockholder may revoke any proxy that is not irrevocable by attending the meeting and voting in person or by delivering to the Secretary a revocation of the proxy or a new proxy bearing a later date.

Any stockholder directly or indirectly soliciting proxies from other stockholders must use a proxy card color other than white, which shall be reserved for exclusive use by the Board of Directors.

(c) Inspector. The Board of Directors, the Chairman of the Board, the Vice Chairman, the Chief Executive Officer, the President, or the person presiding at a meeting of stockholders may appoint one or more persons to act as inspectors of voting at any meeting with respect to any matter to be submitted to a vote of stockholders at such meeting, with such powers and duties, not inconsistent with applicable law, as may be appropriate. Unless otherwise required by applicable law, inspectors may be officers, employees or agents of the Corporation. Each inspector, before entering upon the discharge of the duties of inspector, shall take and sign an oath to execute faithfully the duties of inspector with strict impartiality and according to the best of such inspector’s ability.

Section 2.8 Action by Consent of Stockholders.

(a) Unless otherwise provided in the Certificate of Incorporation, whenever any action by the stockholders at a meeting thereof is required or permitted by law, the Certificate of Incorporation or these Bylaws, such action 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 and bearing the dates of signature of the stockholders who signed the consent, shall be 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 entitled to vote thereon were present and voted and is delivered to the Corporation by delivery to its registered office in the State of Delaware, the Corporation’s principal place of business, or any officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Such delivery shall be by hand or by certified or registered mail, return receipt requested. Prompt notice of the taking of such action without a meeting and by less than unanimous written consent shall be given to those stockholders who have not consented in writing.

(b) No written consent shall be effective to take the corporate action referred to therein unless, within 60 days of the earliest dated written consent received in accordance with this Section 2.8, a written consent or consents signed by a sufficient number of holders to take such action are delivered to the Corporation in the manner prescribed by this Section 2.8.

(c) Any stockholder of record seeking to have the stockholders authorize or take action by written consent shall, by written notice to the Secretary of the Corporation, request the Board of Directors to fix a record date, as provided for in Section 5.8(b).

Section 2.9 Nature of Business at Annual Meetings of Stockholders.

(a) At any annual meeting of stockholders, only such business shall be conducted as shall have been properly brought before such meeting. To be properly brought before an annual meeting, business must be (i) specified in the notice of meeting or proxy materials accompanying such notice (or any supplement thereto) given by or at the direction of the Board of Directors, (ii) otherwise properly brought before the meeting by or at the direction of the Board of Directors or any committee thereof, or (iii) otherwise properly brought before the meeting by a stockholder of record at the time of the delivery of the notice required by this Section 2.9 (the “Record Stockholder”). For the avoidance of doubt, the foregoing clause (iii) shall be the exclusive means for a stockholder to propose business (other than business included in the Corporation’s proxy materials pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (as so amended, and inclusive of rules and regulations adopted thereunder, the “Exchange Act”) or nominations properly made in accordance with Section 3.4 of these Bylaws) at an annual meeting of stockholders.

For business to be properly brought before an annual meeting by a Record Stockholder pursuant to clause (iii) in the preceding paragraph of this Section 2.9(a), (i) the Record Stockholder must have given timely notice thereof in writing to the Secretary of the Corporation in compliance with the notice procedures set forth in this Section 2.9, must be a stockholder of record of the Corporation at the time of the delivery of said notice and at the time of the meeting and must be entitled to vote at the meeting, (ii) any such business must be a proper matter for stockholder action under Delaware law, and (iii) the Record Stockholder and any Stockholder Associated Person (as defined in Section 2.9(d) below) must have acted in accordance with the representations set forth in the Solicitation Statement required by these Bylaws. To be timely, a Record Stockholder’s notice must be delivered to and received by the Secretary at the principal executive offices of the Corporation not later than the close of business on the ninetieth (90th) day, nor earlier than the close of business on the one hundred twentieth (120th) day, prior to the first anniversary of the preceding year’s annual meeting; provided, however, that subject to the immediately following sentence, in the event that the annual meeting is convened more than thirty (30) days before or more than seventy (70) days after such anniversary date, or if no annual meeting was held in the preceding year, notice by the Record Stockholder must be so received not earlier than the close of business on the one hundred twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made by the Corporation. The minimum timeliness requirements of this paragraph shall apply despite any different timeline described in Rule 14a-19 or elsewhere in Regulation 14A under the Exchange Act, including with respect to any statements or information required to be provided to the Corporation pursuant to Rule 14a-19 by a nominating shareholder and not otherwise specified herein. In no event shall the adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of a Record Stockholder’s notice as described above. A Record Stockholder’s notice to the Secretary shall set forth or include, as the case may be, as to each matter the Record Stockholder proposes to bring before the meeting:

(i) a brief description of the business desired to be brought before the meeting, including the complete text of any resolutions to be presented at the meeting with respect to such business (and in the event that such business includes a proposal to amend these Bylaws, the language of the proposed amendment), and the reasons for conducting such business at the meeting;

(ii) the name and address of record of the Record Stockholder and any Stockholder Associated Person;

(iii) the class, series and number of shares of the Corporation which are owned beneficially or of record, directly or indirectly, by the Record Stockholder or any Stockholder Associated Person (and such notice shall include documentary evidence of such person’s record and/or beneficial ownership of such stock); (iv) any material interest including, but not limited to, any direct or indirect financial interest, of the Record Stockholder or any Stockholder Associated Person in such proposed business;

(v) a reasonably detailed description of any agreement, arrangement or understanding (whether written or oral) that the Record Stockholder or any Stockholder Associated Person has with one another or with any other person in connection with such proposed business;

(vi) a reasonably detailed description of any proxy, contract, arrangement, understanding or relationship (whether written or oral) pursuant to which the Record Stockholder or any Stockholder Associated Person has a right to vote, directly or indirectly, any stock of the Corporation or pursuant to which any other person has the right to vote, directly or indirectly, any stock owned by the Record Stockholder or any Stockholder Associated Person;

(vii) a reasonably detailed description of any derivative positions, hedged positions, synthetic or temporary ownership techniques, swaps, securities loans, timed purchases and other economic and voting interests or similar positions held or beneficially held by the Record Stockholder or any Stockholder Associated Person or to which the Record Stockholder or any Stockholder Associated Person is a party with respect to any stock of the Corporation, and whether and the extent to which any other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including any short positions or any borrowing or lending of stock) has been made, the effect or intent of which is to mitigate loss to or manage risk of stock price changes for, or to increase the voting power of, such Record Stockholder or any Stockholder Associated Person with respect to any stock of the Corporation;

(viii) a representation that the Record Stockholder is a holder of record of shares of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business; and

(ix) a representation whether the Record Stockholder or any Stockholder Associated Person intends, or is part of a group which intends, to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the voting power of the Corporation’s outstanding capital stock reasonably believed by the Record Stockholder or Nominating Stockholder Associated Person to be sufficient to approve or adopt the proposal (such representation in this clause (ix), a “Solicitation Statement”).

A Record Stockholder providing notice of business proposed to be brought before an annual meeting shall further update and supplement such notice, if necessary, so that the information provided or required to be provided in such notice pursuant to this Section 2.9(a) shall be true and correct as of the record date for the meeting, and such update and supplement shall be delivered to and received by the Secretary at the principal executive offices of the Corporation not later than ten (10) days after the record date for determining the stockholders entitled to vote at the meeting; provided, that if such date is after the date of the meeting, not later than the day prior to the meeting.

(b) Notwithstanding anything in these Bylaws to the contrary, no business (except for the election of Directors in accordance with the procedures set forth in Section 3.4 of these Bylaws) shall be conducted at an annual meeting except in accordance with the procedures set forth in this Section 2.9. The chairperson of an annual meeting shall have the power to determine and declare to the meeting whether or not business was properly brought before the meeting in accordance with these provisions, and if he or she should determine that business was not properly brought before the meeting, to declare that such business shall not be transacted. Notwithstanding the foregoing provisions of this Section 2.9, unless otherwise required by law or determined by the Board of Directors in its sole discretion, if the Record Stockholder (or a qualified representative of the stockholder) does not appear at the annual meeting of stockholders of the Corporation to present proposed business, such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this Section 2.9, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such stockholder or must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders.

(c) This Section 2.9 is expressly intended to apply to any business proposed to be brought before an annual meeting of stockholders other than any proposal brought properly under and in compliance with Rule 14a-8 under the Exchange Act or any nomination of any person for election to the Board of Directors (which such nomination shall be governed by Section 3.4 of these Bylaws). In addition to the requirements of this Section 2.9 with respect to any business proposed to be brought before an annual meeting, a stockholder shall comply with all applicable requirements of the Exchange Act with respect to any such business. Nothing in this Section 2.9 shall be deemed to affect the rights of stockholders to request inclusion in the Corporation’s proxy statement of proposals pursuant to Rule 14a-8 under the Exchange Act.

(d) For purposes of these Bylaws, the term “Stockholder Associated Person” shall include each of the following persons: (i) any beneficial owner or beneficial owners, if different than the Record Stockholder, on whose behalf the notice of business in this Section 2.9 is made, (ii) any person controlling, directly or indirectly, or acting in concert with the Record Stockholder or such beneficial owner, (iii) any associate (within the meaning of Rule 12b-2 under the Exchange Act for purposes of these Bylaws) of such Record Stockholder, beneficial owner or person and (iv) any other participant in such solicitation (as described in paragraphs (a)(ii)-(vi) of Instruction 3 to Item 4 of Schedule 14A under the Exchange Act).

ARTICLE III

BOARD OF DIRECTORS

Section 3.1 General Powers. The property, business and affairs of the Corporation shall be managed by or under the direction of a Board of Directors. The Board of Directors may exercise all such powers of the Corporation and have such authority and do all such lawful acts and things as are permitted by law, the Certificate of Incorporation or these Bylaws.

Section 3.2 Number of Directors. The Board of Directors of the Corporation shall consist of one or more members. The exact number of Directors which shall constitute the whole Board of Directors shall be fixed from time to time by resolution adopted by a majority of the whole Board of Directors.

Section 3.3 Election. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, after the first meeting of the Corporation at which Directors are elected, Directors of the Corporation shall be elected each year at the annual meeting of stockholders, or at a special meeting in lieu of the annual meeting called for such purpose, by a majority of votes cast at any meeting for the election of Directors at which a quorum is present; provided, however, that, Directors shall be elected by a plurality of the votes cast at any meeting of stockholders for which (i) the Secretary of the Corporation received a notice that a stockholder has nominated a person for election to the Board of Directors in compliance with the advance notice requirements for stockholder nominees for Director set forth in Section 3.4(a) of these Bylaws and (ii) such nomination has not been withdrawn by such stockholder on or prior to the tenth (10th) day preceding the date the Corporation first mails its notice of meeting for such meeting to the stockholders. For purposes of this Section 3.3, a majority of votes cast shall mean that the number of shares of shares voted “for” a nominee’s election exceeded the number of shares voted “against” such nominee’s election. The voting on Directors at any such meeting shall be by written ballot unless otherwise provided in the Certificate of Incorporation.

Section 3.4 Nominations for Election to the Board of Directors.

(a) Only persons who are nominated in accordance with the following procedures shall be eligible for election as Directors. Nominations of persons for election to the Board of Directors may be made at any meeting of stockholders called for the election of Directors by (i) the Board of Directors or any committee designated by the Board of Directors or (ii) any stockholder of the Corporation entitled to vote for the election of Directors at such meeting (a “Nominating Record Stockholder”) if the nomination by such stockholder is made in accordance with the procedures established by this Section 3.4.

For nominations to be properly brought before a meeting by a Nominating Record Stockholder, (a) the Nominating Record Stockholder must have given timely notice thereof in writing to the Secretary of the Corporation in compliance with the notice procedures set forth in this Section 3.4(a), must be a stockholder of the Corporation of record at the time of the delivery of said notice and at the time of the meeting and must be entitled to vote at the meeting for the election of Directors, and (b) the Nominating Record Stockholder and any Nominating Stockholder Associated Person (as defined in Section 3.4(c) below) must have acted in accordance with the representations set forth in the Nominating Solicitation Statement required by these Bylaws.

For the avoidance of doubt, the foregoing sentence shall be the exclusive means for a stockholder to propose nominations at a meeting of stockholders. To be timely with respect to an annual meeting, a stockholder’s notice shall be delivered to and received by the Secretary at the principal executive offices of the Corporation not later than the close of business on the ninetieth (90th) day, nor earlier than the close of business on the one hundred twentieth (120th) day, prior to the first anniversary of the preceding year’s annual meeting; provided, however, that subject to the next two sentences, in the event that the annual meeting is convened more than thirty (30) days before or more than seventy (70) days after such anniversary date, or if no annual meeting was held in the preceding year, notice by the Nominating Record Stockholder must be so received not earlier than the close of business on the one hundred twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made by the Corporation. Notwithstanding anything in the preceding sentence to the contrary, in the event that the number of Directors to be elected to the Board of Directors is increased and there has been no public announcement naming all of the nominees for Director or indicating the increase in the size of the Board of Directors made by the Corporation at least ten (10) days before the last day that a Nominating Record Stockholder may deliver a notice of nomination in accordance with the preceding sentence, a Nominating Record Stockholder’s notice required by this Section 3.4(a) shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be received by the Secretary not later than the close of business on the tenth (10th) day following the day on which such public announcement is first made by the Corporation. In no event shall the adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of a Nominating Record Stockholder’s notice as described above.

A Nominating Record Stockholder’s notice to the Secretary shall set forth or include, as the case may be:

Such record shall show the name and address of the stockholder in which the shares of capital stock are registered; the number of shares held by such stockholder; the numbers of the certificates covering such shares, if certificated; the date of each such certificate; and in case of certificates which have been cancelled, the dates of cancellation thereof.

The Corporation shall be entitled to treat the holder of record of shares of capital stock as shown on the stock ledger as the owner thereof and as the person entitled to receive dividends thereon, to vote such shares and to receive notice of meetings, and for all other purposes. The Corporation shall not be bound to recognize any equitable or other claim to or interest in any share of capital stock on the part of any other person whether or not the Corporation shall have express or other notice thereof.

Section 5.4 Regulations Relating to Transfer. The Board of Directors may make such rules and regulations as it may deem expedient and not inconsistent with law, the Certificate of Incorporation or these Bylaws concerning the issuance, transfer and registration of shares of capital stock of the Corporation. The Board of Directors may appoint, or authorize any principal officer to appoint, one or more transfer clerks, transfer agents or registrars and may require all certificates for capital stock to bear the signature or signatures of any of them.

Section 5.5 Transfers. Upon surrender to the Corporation or the transfer agent of the Corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignation or authority to transfer, the Corporation shall issue a new certificate or evidence of the issuance of uncertificated shares to the person entitled thereto, cancel the old certificate and record the transaction upon the Corporation’s books. Upon the receipt of proper transfer instructions from the registered owners of uncertificated shares, such uncertificated shares shall be cancelled, issuance of new equivalent uncertificated or certificated shares shall be made to the person entitled thereto and the transaction shall be recorded upon the books of the Corporation.

Section 5.6 Cancellation. Each certificate for capital stock surrendered to the Corporation for exchange or transfer shall be cancelled and no new certificate or certificates shall be issued in exchange for any existing certificate (other than pursuant to Section 5.7) until such existing certificate shall have been cancelled.

Section 5.7 Lost, Destroyed, Stolen and Mutilated Certificates. In the event that any certificate for shares of capital stock of the Corporation shall be mutilated, the Corporation shall issue a new certificate or uncertificated shares in place of such mutilated certificate. In case any such certificate shall be lost, stolen or destroyed, the Corporation may, in the discretion of the Board of Directors or a committee designated thereby with power so to act, issue a new certificate for capital stock or uncertificated shares in the place of any such lost, stolen or destroyed certificate. The applicant for any substituted certificate or certificates or uncertificated shares shall surrender any mutilated certificate or, in the case of any lost, stolen or destroyed certificate, furnish satisfactory proof of such loss, theft or destruction of such certificate and of the ownership thereof. The Board of Directors or such committee may, in its discretion, require the owner of a lost, stolen or destroyed certificate, or his or her representatives, to furnish to the Corporation a bond with an acceptable surety or sureties and in such sum as will be sufficient to indemnify the Corporation against any claim that may be made against it on account of the lost, stolen or destroyed certificate or the issuance of such new certificate or uncertificated shares. A new certificate or uncertificated shares may be issued without requiring a bond when, in the judgment of the Board of Directors, it is proper to do so.

Section 5.8 Fixing of Record Dates.

(a) Stockholder Meetings; Adjournments. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If the Board of Directors so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board of Directors determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the determination of stockholders entitled to vote at the adjourned meeting and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for the determination of stockholders entitled to vote therewith at the adjourned meeting.

(b) Stockholder Action by Consent. In order that the Corporation may determine the stockholders entitled to consent to action in writing without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than ten (10) days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. Any stockholder of record seeking to have the stockholders authorize or take action by written consent shall, by written notice to the Secretary of the Corporation, request the Board of Directors to fix a record date. The Board of Directors shall promptly, but in all events within ten (10) days after the date on which such a request is received, adopt a resolution fixing the record date (unless a record date has previously been fixed by the Board of Directors pursuant to the first sentence of this Section 5.8(b)). If no record date has been fixed by the Board of Directors within ten (10) days of the date on which such a request is received, the record date for determining stockholders entitled to consent to action in writing without a meeting, when no prior action by the Board of Directors is required by applicable law, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or any officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested.

If no record date has been fixed by the Board of Directors and prior action by the Board of Directors is required by applicable law, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the date on which the Board of Directors adopts the resolution taking such prior action.

(c) Distributions, Allotment of Rights, Exercise of Rights, and Other Purposes. In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights or the stockholders entitled to exercise any rights in respect of any change, conversion, or exchange of stock, or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than 60 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

Exhibit 10.1

ADTRAN HOLDINGS, INC.

POLICY FOR THE RECOVERY OF

ERRONEOUSLY AWARDED COMPENSATION

1. Purpose. The purpose of this Policy is to describe the circumstances in which Executive Officers will be required to repay, return, or forfeit Erroneously Awarded Compensation to the Company. This Policy shall be interpreted to comply with Rule 10D-1 promulgated under the Securities Exchange Act of 1934, as amended, and the related listing rules of the Exchange, and, to the extent this Policy is deemed inconsistent with such rules in any manner, this Policy shall be treated as retroactively amended to be compliant with such rules. Capitalized terms shall have the meanings ascribed to such terms in Section 3 below.

2. Administration. This Policy shall be administered by the Committee. The Committee has full and final authority to make all determinations under this Policy, in each case to the extent permitted under the listing rules of the Exchange and in compliance with (or pursuant to an exemption from the application of) Section 409A of the Code. Any determinations made by the Committee shall be final and binding on all affected individuals.

3. Definitions. For purposes of this Policy, the following capitalized terms shall have the meanings set forth below.

(a) “Accounting Restatement” shall mean an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial restatements that is material to the previously issued financial statements (a “Big R” restatement), or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period (a “little r” restatement).

(b) “Board” shall mean the Board of Directors of the Company.

(c) “Clawback Eligible Incentive Compensation” shall mean all Incentive-based Compensation Received by an Executive Officer (i) on or after October 2, 2023, (ii) after beginning service as an Executive Officer, (iii) who served as an Executive Officer at any time during the applicable performance period for such Incentive-based Compensation (whether or not such Executive Officer is serving at the time the Erroneously Awarded Compensation is required to be repaid, returned, or forfeited to the Company Group), (iv) while the Company has a class of securities listed on a national securities exchange or a national securities association, and (v) during the applicable Clawback Period.

(d) “Clawback Period” shall mean, with respect to any Accounting Restatement, the three completed fiscal years of the Company immediately preceding the Restatement Date, including any transition period (that results from a change in the Company’s fiscal year) of less than nine months within or immediately following those three completed fiscal years.

(e) “Code” shall mean the U.S. Internal Revenue Code of 1986, as amended. Any reference to a section of the Code or regulation thereunder includes such section or regulation, any valid regulation or other official guidance promulgated under such section, and any comparable provision of any future legislation or regulation amending, supplementing, or superseding such section or regulation.

(f) “Committee” shall mean the Compensation Committee (if composed entirely of independent directors) of the Board, or, in the absence of such a committee, a majority of the independent directors serving on the Board.

(g) “Company” shall mean ADTRAN Holdings, Inc., a Delaware corporation.

(h) “Company Group” shall mean the Company, together with each of its direct and indirect subsidiaries.

(i) “Effective Date” shall mean October 2, 2023.

(j) “Erroneously Awarded Compensation” shall mean, with respect to each Executive Officer in connection with an Accounting Restatement, the amount of Clawback Eligible Incentive Compensation Received that exceeds the amount of Incentive-based Compensation that otherwise would have been Received had it been determined based on the restated amounts, computed without regard to any taxes paid. For Incentive-based Compensation based on (or derived from) stock price or total stockholder return where the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in the applicable Accounting Restatement, the amount shall be determined by the Committee based on a reasonable estimate of the effect of the Accounting Restatement on the stock price or total stockholder return upon which the Incentive-based Compensation was Received (in which case, the Company shall maintain documentation of such determination of that reasonable estimate and provide such documentation to the Exchange). With respect to any compensation plans or programs of the Company Group that take into account Incentive-Based Compensation, the amount of Erroneously Awarded Compensation subject to recovery (or, to the extent such amount has not yet been paid, forfeiture) under this Policy includes, but is not limited to, the amount of Erroneously Awarded Compensation credited to any notional account and any notional earnings attributable thereto.

(k) “Exchange” shall mean a national securities exchange or national securities association on which the Company has listed securities.

(l) “Executive Officer” shall mean each individual who is currently or was previously designated as an “officer” of the Company in accordance with Rule 16a-1(f) of the Securities Exchange Act of 1934, as amended.

(m) “Financial Reporting Measure” shall mean a measure that is determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any other measure that is derived wholly or in part from such measure. Stock price and total stockholder return (and any measure that is derived wholly or in part from stock price or total stockholder return) shall be considered Financial Reporting Measures for purposes of this Policy. For the avoidance of doubt, a Financial Reporting Measure need not be presented in the Company’s financial statements or included in a filing with the SEC.

2

(n) “Incentive-based Compensation” shall mean any compensation that is granted, earned or vested based wholly or in part upon the attainment of a Financial Reporting Measure.

(o) “Policy” shall mean this Policy for the Recovery of Erroneously Awarded Compensation, as the same may be amended and/or restated from time to time.

(p) “Received” shall, with respect to any Incentive-based Compensation, mean deemed receipt, and Incentive-based Compensation shall be deemed received in the Company’s fiscal period during which the Financial Reporting Measure specified in the Incentive-based Compensation award is attained, even if payment or grant of the Incentive-based Compensation occurs after the end of that period (subject to applicable law, including any Incentive-based Compensation the payment of which has been deferred). For the avoidance of doubt, Incentive-based Compensation that is subject to both a Financial Reporting Measure vesting condition and a service-based vesting condition shall be considered received when the relevant Financial Reporting Measure is achieved, even if the Incentive-based Compensation continues to be subject to the service-based vesting condition.

(q) “Restatement Date” shall mean the earlier to occur of (i) the date the Board, a committee of the Board or the officers of the Company authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare an Accounting Restatement, or (ii) the date a court, regulator, or other legally authorized body directs the Company to prepare an Accounting Restatement.

(r) “SEC” shall mean the U.S. Securities and Exchange Commission.

4. Recovery of Erroneously Awarded Compensation.

(a) In the event that the Company is required to prepare an Accounting Restatement, the Company must recover, reasonably promptly, Erroneously Awarded Compensation Received by any Executive Officer during the applicable Clawback Period, in amounts determined by the Committee pursuant to this Policy. The Company’s obligation to recover Erroneously Awarded Compensation is not dependent on if or when the Company files restated financial statements. Recovery under this Policy with respect to an Executive Officer shall not require the finding of any misconduct by such Executive Officer or such Executive Officer being found responsible for the accounting error leading to an Accounting Restatement. In the event of an Accounting Restatement, the Committee shall determine, in its sole and absolute discretion, the timing and method for promptly recovering Erroneously Awarded Compensation hereunder, including, without limitation, the cancellation of or offsetting against any planned future cash or equity-based awards, to the extent permitted under the listing rules of the Exchange and in compliance with (or pursuant to an exemption from the application of) Section 409A of the Code. The Committee has the power, in its sole discretion, to retain or obtain the advice of a compensation consultant, legal counsel or other adviser as it deems necessary or appropriate to carry out its duties under this Policy.

3

(b) Notwithstanding anything herein to the contrary, the Company shall not be required to take the actions contemplated by Section 4(a) above to the extent that one or more of the following conditions are met and the Committee determines that recovery would therefore be impracticable:

(i) The direct expense paid to a third party to assist in enforcing this Policy against an Executive Officer would exceed the amount to be recovered, after the Company has made a reasonable attempt to recover the applicable Erroneously Awarded Compensation, documented such attempts and provided such documentation to the Exchange; or

(ii) Recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of any member of the Company Group, to fail to meet the requirements of Section 401(a)(13) or Section 411(a) of the Code.

5. Reporting and Disclosure. The Company shall file all disclosures with respect to this Policy in accordance with the requirements of the federal securities laws, including the disclosures required by applicable SEC filings.

6. Indemnification Prohibition. No member of the Company Group shall be permitted to indemnify any Executive Officer against the loss of any Erroneously Awarded Compensation that is repaid, returned, recovered, or forfeited pursuant to the terms of this Policy, including any payment or reimbursement for the cost of third-party insurance purchased by an Executive Officer to cover such losses incurred under this Policy. Further, no member of the Company Group shall enter into any agreement that exempts any Incentive-based Compensation from the application of this Policy or that waives the Company Group’s right to recovery of any Erroneously Awarded Compensation, and this Policy shall supersede any such agreement (whether entered into before, on, or after the Effective Date).

7. Interpretation. The Committee is authorized to interpret and construe this Policy and to make all determinations necessary, appropriate, or advisable for the administration of this Policy.

8. Effective Date. This Policy shall be effective as of the Effective Date.

9. Amendment; Termination. The Board may amend this Policy from time to time in its discretion and shall amend this Policy as it deems necessary, including as and when it determines that it is legally required by any federal securities laws, SEC rules, or the listing rules of the Exchange. The Board may terminate this Policy at any time. Notwithstanding anything in this Section 9 to the contrary, no amendment or termination of this Policy shall be effective if such amendment or termination would (after taking into account any actions taken by the Company contemporaneously with such amendment or termination) cause the Company to violate any federal securities laws, SEC rules or the listing rules of the Exchange.

4

10. Acknowledgment; Benefits Conditioned on Agreeing to this Policy. Each Executive Officer shall be required to sign and return to the Company, within thirty (30) calendar days following the later of (i) the Effective Date of this Policy or (ii) the date the individual becomes an Executive Officer, the Acknowledgment Form attached hereto as Exhibit A, pursuant to which such Executive Officer will agree to be bound by the terms of this Policy. Any employment agreement, equity award agreement, compensatory plan or any other agreement or arrangement with an Executive Officer shall be deemed to include, as a condition to the grant or receipt of any benefit thereunder, an agreement by the Executive Officer to abide by, and for such Executive Officer and his/her Incentive-based Compensation to be subject to, the terms of this Policy. For the avoidance of doubt, each Executive Officer will be fully bound by, and must comply with, this Policy, whether or not such Executive Officer has executed and returned such Acknowledgment Form to the Company.

11. Other Recoupment Rights; Company Claims. The Board intends that this Policy will be applied to the fullest extent of the law. This Policy should be considered as a supplement to any other clawback policy in effect now or in the future at the Company or any other member of the Company Group, and if such other policy provides that a greater amount of compensation shall be subject to clawback, such other policy shall apply to the amount in excess of the amount subject to clawback under this Policy. Any right of recoupment (or right to apply a forfeiture) under this Policy is in addition to, and not in lieu of, any other remedies or rights of recoupment (or forfeiture) that may be available to the Company Group under applicable law, regulation, or rule or pursuant to the terms of any similar policy in any employment agreement, compensation plan or program, award agreement, or similar document and any other legal remedies available to the Company Group, in each case to the extent permitted under the listing rules of the Exchange and in compliance with (or pursuant to an exemption from the application of) Section 409A of the Code. Nothing contained in this Policy, and no recoupment, recovery, or forfeiture as contemplated by this Policy, shall limit any claims, damages, or other legal remedies the Company Group may have against an Executive Officer arising out of or resulting from any actions or omissions by the Executive Officer.

11. Successors. This Policy shall be binding and enforceable against all Executive Officers and their beneficiaries, heirs, executors, administrators or other legal representatives.

ERRONEOUSLY AWARDED COMPENSATION

Policy for the Recovery of Erroneously Awarded Compensation (the “Policy”). Capitalized terms used but not otherwise defined in this Acknowledgment Form (this “Acknowledgment Form”) shall have the meanings ascribed to such terms in the Policy.

By signing this Acknowledgment Form, the undersigned acknowledges and agrees that the undersigned and the undersigned’s Incentive-based Compensation are and will continue to be subject to the Policy and that the Policy will apply both during and after the undersigned’s employment with any member of the Company Group. In the event of any inconsistency or conflict between the Policy and any prior, existing or future employment agreement, compensation plan or program, award agreement or similar document to which the undersigned is or becomes a party or that otherwise is or becomes applicable to the undersigned (collectively, “compensation arrangements”), the undersigned acknowledges and agrees that the Policy shall govern such compensation arrangements, and all such compensation arrangements are hereby automatically deemed amended to the extent necessary to give effect to the Policy. Further, by signing below, the undersigned agrees to abide by the terms of the Policy, including, without limitation, by (i) waiving any rights to indemnification or any claim to insurance under a policy paid for by the Company, in either case in connection with the recovery of Erroneously Awarded Compensation under the Policy and (ii) returning any Erroneously Awarded Compensation to the extent required by the Policy.

Exhibit 10.2

AMENDED AND RESTATED CLAWBACK POLICY

On January 18, 2011, the Board of Directors (the “Board”) of ADTRAN, Inc., the predecessor of ADTRAN Holdings, Inc. (the “Company”), formally approved, upon the recommendation of the Compensation Committee of the Board (the “Committee”), this policy of recoupment for incentive-based compensation in certain circumstances (this “Policy”). This Policy was assumed by the Company on July 6, 2022, and it was amended and restated effective as of October 2, 2023. This Policy was originally adopted in order to comply with Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Section 954”) prior to the time that the Securities and Exchange Commission (the “SEC”) and The Nasdaq Stock Market (“Nasdaq”) adopted final rules implementing Section 954, and to help ensure executive officers act in the best interests of the Company. The SEC adopted final rules implementing Section 954 effective January 27, 2023, and Nasdaq adopted listing rules in compliance with such SEC rules effective October 2, 2023. In order to comply with Nasdaq listing rules, the Company has adopted a new Policy for the Recovery of Erroneously Awarded Compensation (the “Recoupment Policy”), which Recoupment Policy applies with respect to all compensation Received (as defined in the Recoupment Policy) on or after October 2, 2023. This Policy applies to incentive compensation Received prior to October 2, 2023.

Following an accounting restatement due to material noncompliance with any financial reporting requirements under the securities laws, the Company will recover, to the extent permitted by governing law, any incentive compensation awarded, earned, vested or paid to its executive officers (as such term is defined by the Securities Exchange Commission) to the extent’ such incentive compensation was paid or settled as the result of the achievement of financial results that were subsequently the subject of such restatement due to material noncompliance with any financial reporting requirement under the federal securities laws, regardless of individual fault.

This Policy applies to any incentive compensation settled with or paid to an executive officer by the Company prior to October 2, 2023. Subsequent changes in status, including retirement or termination of employment, do not affect the Company’s rights to recover compensation under this Policy.

The Committee will administer this Policy and exercise its discretion and business judgment in the fair application of this Policy based on the facts and circumstances as it deems relevant in its sole discretion. More specifically, the Committee shall determine the appropriate amounts to recoup, the officers from whom such amounts shall be recouped and the timing and form of recoupment; provided, that only compensation paid or settled during the three-year period preceding the date on which the Company is required to prepare an accounting restatement shall be subject to recoupment; provided further, that the recoupment shall not exceed the portion of applicable incentive compensation that is in excess of the amount of incentive compensation that would have been paid or settled based on the actual, restated financial statements. For avoidance of doubt, the Company may set off the amounts of any such required recoupment against any amounts otherwise owed by the Company to an executive officer as determined by the Committee in its sole discretion, to the extent any such offset complies with the requirements of Section 409A of the Internal Revenue Code and the guidance issued thereunder.

If any restatement of the Company’s financial results indicates that the Company should have made higher performance-based payments than those actually made for a period affected by the restatement, then the Committee shall have discretion, but not the obligation, to cause the Company to make appropriate incremental payments to affected officers then-currently employed by the Company. The Committee will determine, in its sole discretion, the amount, form and timing of any such incremental payments, which shall be no more than the difference between the amount of incentive compensation that was paid or awarded and the amount that would have been paid or granted based on the actual, restated financial statements.

ADTRAN HOLDINGS, INC.

AMENDED AND RESTATED CLAWBACK AGREEMENT

ADTRAN Holdings, Inc. (the “Company”) has adopted an Amended and Restated Clawback Policy (the “Policy”) that requires executive officers who receive incentive based compensation to agree to the terms of this Clawback Agreement (this “Agreement”). The Policy provides for the recoupment of certain executive incentive based compensation received in error as determined by accounting restatements resulting from material noncompliance with financial reporting requirements under the federal securities laws. Capitalized terms used but not defined in this Agreement shall have the meaning ascribed to such terms in the Policy.

AGREED TO as of [____].
