2.1 Meeting Place. All meetings of the stockholders shall be held, pursuant to proper notice as set forth in Section 2.4 of this Article II, at the principal executive office of the Corporation, or at such other place as shall be determined from time to time by the Board of Directors. The Board of Directors may, in its sole discretion, determine that the meeting may be held solely by means of remote communication, as authorized by Section 211(a) of the General Corporation Law of the State of Delaware (the DGCL).

2.2 Annual Meeting. The annual meeting of the stockholders shall be held on such date and at such time as shall be fixed by resolution of the Board of Directors, at the principal office of the Corporation, or such other place as fixed by the Board of Directors, for the purpose of electing directors and transacting such other business as may properly come before that meeting; provided, however, that the Board of Directors may, in its sole discretion, determine that the meeting shall not be held at any place, but may instead be held solely by means of remote communication as authorized by Section 211 of the DGCL.

2.3 Special Meetings. Special meetings of the stockholders for any purpose may be called at any time by the President, the Board of Directors or the holders of at least ten percent of all the votes entitled to be cast on any issue proposed to be considered at such special meeting. Special meetings of the stockholders shall be held at the Corporation’s principal executive office or at such other place as shall be identified in the notice of such meeting. Only business within the purpose or purposes described in the meeting notice may be conducted at a special stockholders’ meeting.

2.4 Notice of Meetings. Except as otherwise provided by applicable law or the Certificate of Incorporation, whenever stockholders are required or permitted to take any action at a meeting, notice in writing or by electronic transmission of each stockholders’ meeting stating the date, time, place, and 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, and, for a special meeting, the purpose(s) for which the meeting is called, shall be given by the Corporation not less than ten nor more than sixty days prior to the date of the meeting, to each stockholder of record pursuant to Article VII of these Bylaws.

Any previously scheduled meeting of the stockholders may be postponed by resolution of the Board of Directors, except that a meeting requested by the holders of record of shares of stock pursuant to Section 2.3 of these Bylaws may be postponed only by the holders of record that requested the meeting.

2.6 The Board of Directors or the chairperson at any meeting shall have the power to adjourn a meeting of stockholders. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time, place (if any) thereof and 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 adjourned meeting are announced at the meeting at which the adjournment is taken. At the adjourned meeting the Corporation may transact any business that might have been transacted at the original meeting. If the adjournment is for more than 30 days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for stockholders entitled to vote is fixed for the adjourned meeting, the Board shall fix a new record date for determining stockholders entitled to notice of such adjournment meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote at the adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record entitled to vote at such adjourned meeting as of the record date fixed for notice of such adjourned meeting.

2.7 Fixing of Record Date. In order that the Corporation may determine the stockholders entitled to notice of 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, unless otherwise required by law, 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 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 determination of stockholders entitled to vote in accordance herewith at the adjourned meeting.

3

The record date for determining the stockholders entitled to consent to corporate action in writing without a meeting shall not be more than 10 days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no such record date is fixed by the Board of Directors, the record date shall be determined as follows:

(a) if no prior action by the Board of Directors is required under the DGCL, the record date 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; and

(b) if prior action by the Board of Directors is required under the DGCL, the record date shall be the close of business on the day on which the Board of Directors adopts a resolution taking such prior action.

The record date for determining the stockholders entitled to receive payment of any dividend or other distribution or allotment of 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, shall be not more than 60 nor less than 10 days prior to such action. If no such record date is fixed by the Board of Directors, the record date for determining the stockholders for any such purpose shall be the close of business on the day on which the Board of Directors adopts the resolution relating to such purpose.

2.8 Stockholders’ List. The Corporation shall prepare, at least ten days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting (provided, however, if the record date for determining the stockholders entitled to vote is less than ten (10) 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 in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder for any purpose

4

germane to the meeting at least ten (10) days prior to the meeting (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of meeting or (ii) during ordinary business hours at the principal place of business of the Corporation. If the meeting is to be held at a place, then a list of stockholders entitled to vote at the meeting shall be produced and kept at the time and place of the meeting during the whole time thereof and may be examined by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. Except as otherwise provided by law, the stock ledger shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders required by this Section 2.8 or to vote in person or by proxy at any meeting of stockholders.

2.9 Quorum and Adjourned Meetings. Except as otherwise provided in the Certificate of Incorporation or otherwise provided by law, a quorum at any annual or special meeting of stockholders shall consist of stockholders representing, either in person or by proxy, one-third of the votes entitled to be cast on the matter. The stockholders present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. The chairman of the meeting may adjourn the meeting from time to time, whether or not there is such a quorum. No notice of the time and place of adjourned meetings need be given except as provided in the last paragraph of Section 2.6 of these Bylaws.

2.10 Voting. Except as otherwise provided in the Certificate of Incorporation or by law, each outstanding share, regardless of class, is entitled to one vote on each matter voted on at a stockholders’ meeting.

If a quorum exists, then, other than in the election of directors, action on a matter is approved by the vote of the holders of shares of stock having a majority in voting power of the votes cast by the holders of all shares of stock present or represented at the meeting and voting affirmatively or negatively on such matter.

5

Unless otherwise provided in the Certificate of Incorporation, in any election of directors for which a quorum is present, the candidates elected are those receiving a majority of votes cast by the shares entitled to vote in the election; provided that, if the election is contested, the candidates elected are those receiving a plurality of the votes cast by the shares entitled to vote in the election. An election shall be contested if, as determined by the Board of Directors, the number of candidates for director exceeds the number of directors to be elected. For the purposes of this Section 2.10, a majority of votes cast shall mean that the number of votes cast “for” a director’s election exceeds the number of votes cast “against” that director’s election (with abstentions and broker non-votes not counted as a vote cast either “for” or “against” such director’s election).

2.11 Proxies. A stockholder may vote either in person or by granting a proxy in accordance with applicable law. An appointment of a proxy is valid for three years unless a longer period is expressly provided in the appointment form.

2.12 Stockholder Action by Written Consent. Except as otherwise provided by the Certificate of Incorporation, any action required to be taken at any annual or special meeting of stockholders of the Corporation, or any action which may be taken at any annual or special meeting of the stockholders of the Corporation, may be taken without a meeting, without prior notice and without a vote, only if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of all the outstanding shares of stock of the Corporation entitled to vote thereon and shall be delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded.

6

2.13 Stockholder Nomination of Director Candidates.

(a) Subject to the rights of holders of any class or series of stock having a preference over the Corporation’s common stock as to dividends or upon liquidation, if any, nominations for the election of directors may be made by the Board of Directors or a committee appointed by the Board of Directors or by any stockholder who is a stockholder of record of the Corporation at the time the notice provided for in this Section 2.13 is delivered to the Corporation and who is entitled to vote in the election of directors generally at the applicable meeting of stockholders. However, any stockholder entitled to vote in the election of directors generally may nominate one or more persons for election as directors at a meeting only if written notice of such stockholder’s intent to make such nomination or nominations has been received by the Corporation, either by personal delivery or by United States mail, postage prepaid, to the Secretary of the Corporation not later than (i) with respect to the election to be held at an annual meeting of stockholders, not less than ninety days nor more than one hundred twenty days prior to the date one year from the date of the immediately preceding annual meeting of stockholders; provided, however, that in the event that the annual meeting is called for a date that is not within thirty days before or after the date one year from the date of the immediately preceding annual meeting of stockholders, or no annual meeting was held in the immediately preceding year, notice by the stockholder in order to be timely must be so received no later than the close of business on the tenth day following the day on which the public announcement is first made of the date of the annual meeting; and (ii) with respect to an election to be held at a special meeting of stockholders for the election of directors, the close of business on the tenth day following the date on which the public announcement is first made of the date of the special meeting.

7

been nominated or intended to be nominated, by the Board of Directors; and (E) the consent of each nominee to serve as a director of the Corporation if so elected. This Section 2.13 of this Article II shall be the exclusive means for a stockholder to submit nominations of persons for election to the Board of Directors. The Chairperson of the meeting may in his or her discretion determine and declare to the meeting that a nomination was not made in accordance with the foregoing procedures, and if he or she should so determine, he or she shall so declare to the meeting and the defective nomination shall be disregarded.

(b) Notwithstanding anything to the contrary in these Bylaws, unless otherwise required by law, (i) no person shall be eligible for election as a director of the Corporation pursuant to a stockholder nomination unless nominated in accordance with the procedures (including providing the required information) set forth in this Section 2.13 of this Article II, whether such proposed nominee is to be included in the Corporation’s proxy statement or presented to stockholders by means of an independently financed proxy solicitation and (ii) if the stockholder (or a qualified representative) giving the notice does not appear at the meeting to present the nomination, such nomination may be disregarded, irrespective of whether proxies concerning such nomination have been received by the Corporation.

2.14 Stockholder Proposals.

(a) Any stockholder who is a stockholder of record of the Corporation at the time the notice provided for in this Section 2.14 is delivered to the Corporation and who is entitled to vote at a meeting of stockholders may make any proposal at such meeting of stockholders and the same may be discussed and considered only if written notice of such stockholder’s intent to make such proposal(s) has been received by the Corporation, either by personal delivery or by United States mail, postage prepaid, to the Secretary of the Corporation (i) for purposes of an annual meeting, not less than ninety days nor more than one hundred twenty days prior to the date one year from the date of the immediately preceding annual meeting of stockholders; provided, however, that in

8

the event that the annual meeting is called for a date that is not within thirty days before or after the date one year from the date of the immediately preceding annual meeting of stockholders, or no annual meeting was held in the immediately preceding year, notice by the stockholder in order to be timely must be so received no later than the close of business on the tenth day following the day on which the public announcement is first made of the date of the annual meeting; and (ii) for purposes of a special meeting, not less than ninety days nor more than one hundred twenty days prior to the date of such special meeting of stockholders; provided, however, that if the first public announcement of the date of such special meeting is less than one hundred days prior to the date of such special meeting, notice by the stockholder in order to be timely must be so received no less than the tenth day following the day on which public announcement is first made of the date of the special meeting. In no event shall any adjournment or postponement of a special meeting or a public announcement thereof commence a new time period (or extend any time period) for the giving of a stockholder’s notice. Each such notice shall be in writing and shall set forth: (i) the address of the stockholder who intends to make the proposal(s); (ii) a representation that the stockholder is a holder of record of stock of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to vote for the proposal(s); and (iii) such other information regarding each proposal as would be required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission. The Chairperson of the meeting may in his discretion determine and declare to the meeting that a proposal was not made in accordance with the foregoing procedures, and if he should so determine, he shall so declare to the meeting and the defective proposal shall be disregarded.

(b) Notwithstanding anything to the contrary in these Bylaws: (i) no business shall be conducted at any meeting of stockholders except in accordance with the procedures set forth in this Section 2.14 of this Article II (other than the nomination of a person for election as a director, which is governed by Section 2.13 of this Article II and any business brought by the Board of Directors), and (ii) unless otherwise required by law, if a stockholder intending to propose business at a meeting of stockholders does not comply with the procedures (including providing the required information) set forth in this Section 2.14 of this Article II or if such stockholder (or a qualified representative) does not appear at the meeting to present the proposed business, such business shall not be transacted, irrespective of whether proxies concerning such nomination have been received by the Corporation.

(c) Without limiting the foregoing provisions of this Section 2.14 of this Article II (and with respect to the nomination of a person for election as a director, Section 2.13 of this Article II), a stockholder shall also comply with all applicable requirements of the Securities Exchange Act of 1934, as amended (the Exchange Act), and the rules and regulations thereunder with respect to the matters set forth in this Section 2.14 of this Article II; provided, however, that any references in these Bylaws to the Exchange Act or such rules and regulations are not intended to and shall not limit any requirements applicable to nominations or proposals as to any other business to be considered pursuant to this Section 2.14, and compliance with this Section 2.14 of this Article II shall be the exclusive means for a stockholder to make nominations or submit other business. Nothing in these Bylaws shall be deemed to affect any rights (i) of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 (or any successor provision) under the Exchange Act or (ii) of the Corporation to omit a proposal from the Corporation’s proxy statement pursuant to Rule 14a-8 (or any successor provision) under the Exchange Act, or (iii) of the holders of any series of Preferred Stock, if any, to the extent provided for under law, the Certificate of Incorporation or these Bylaws.

11

(b) Shares of certificated stock shall be transferred by delivery of the certificates therefor, accompanied either by an assignment in writing on the back of the certificate or an assignment separate from certificate, or by a written power of attorney to sell, assign and transfer the same, signed by the holder of said certificate.

14

4.11 Waiver of Notice.

The Corporation shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is made or is threatened to be made a party or is otherwise involved in any threatened, pending, or completed action, suit or proceeding, whether civil, criminal, administrative or investigative and whether or not brought by or in the right of the Corporation (a Proceeding) by reason of the fact that such person, or any other person for whom such person is the legal representative, is or was a director or officer of the Corporation, or while a director or officer of the Corporation is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, other enterprise or non-profit entity, including service with respect to employee benefit plans (an Indemnitee), against all liability and loss suffered and expenses (including attorneys’ fees) reasonably incurred by such Indemnitee if such Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any Proceeding, had no reasonable cause to believe that the Indemnitee’s conduct was unlawful. The indemnification provided in this Section 9.1 and the advancement of expenses provided in Section 9.2 of these Bylaws shall, unless otherwise provided when authorized or ratified by the Board of Directors, continue as to an Indemnitee who has ceased to be a director, officer, employee or agent as aforesaid and shall inure to the benefit of the heirs, executors and administrators of such Indemnitee. Any indemnification under this Section 9.1 (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that the indemnification of the Indemnitee is proper in the circumstances because such Indemnitee has met the applicable standard of conduct set forth in this Section. Such determination shall be made, with respect to an Indemnitee who is a director or officer at the time of

23

such determination, (1) by majority vote of the directors who are not party to such Proceeding, even though less than a quorum, or (2) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (3) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (4) by the stockholders.

9.2 Advancement of Expenses. The Corporation shall pay the expenses (including attorneys’ fees) incurred by an Indemnitee in defending any Proceeding referred to in Section 9.1 of these Bylaws in advance of its final disposition; provided that the payment of expenses incurred by an Indemnitee in advance of the final disposition of such Proceeding shall be made only upon receipt of (i) a written affirmation of the Indemnitee’s good faith belief that the Indemnitee met the requisite standard of conduct and (ii) an undertaking by the Indemnitee to repay all amounts advanced if it should ultimately be determined that the Indemnitee is not entitled to be indemnified under this Article or otherwise.

9.3 Claims. If a claim for indemnification or advancement of expenses under this Article is not paid in full within sixty (60) days after a written claim therefore by the Indemnitee has been received by the Corporation, the Indemnitee may file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of such claim. In any such action the Corporation shall have the burden of proving that the Indemnitee was not entitled to the requested indemnification or advancement of expenses.

9.4 Good Faith Defined. For purposes of any determination under Section 9.1, a person shall be deemed to have acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, or, with respect to any criminal action or proceeding, to have had no reasonable cause to believe such person’s conduct was unlawful, if such person’s action is based on good faith reliance on the records or books of account of the Corporation or another enterprise, or on information supplied to such person by the officers of the Corporation or another enterprise in the course of their duties, or on the advice of legal counsel for the Corporation or another enterprise or on information or records given or reports made to the Corporation or another enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Corporation or another enterprise.

24

9.5 Indemnification of Employees and Agents. The Corporation may indemnify employees and agents of the Corporation pursuant to this Article IX to the same extent as an Indemnitee.

9.6 Non-exclusivity of Rights. The right to indemnification under this Article IX for directors, officers, employees and agents shall not be exclusive of any other right which any person may have, or hereafter acquire, under any statute, provision of the Certificate of Incorporation, these Bylaws, other agreement, vote of stockholders or disinterested directors, insurance policy, principles of common law or equity, or otherwise.

9.7 Other Indemnification. The Corporation’s obligation, if any, to indemnify any Indemnitee who was or is serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or non-profit entity shall be reduced by any amount such Indemnitee may collect as indemnification from such other corporation, partnership, joint venture, trust, enterprise or nonprofit entity.

9.8 Amendment or Repeal; Survival. Any repeal or modification of the foregoing provisions of this Article shall not adversely affect any right or protection hereunder of any Indemnitee in respect of any act or omission occurring prior to the time of such repeal or modification. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article IX shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

25

9.9 Insurance. The Corporation may purchase and maintain insurance on behalf of an individual who is or was a director, officer, employee, or agent of the Corporation, or who, while a director, officer, employee, or agent of the Corporation, is or was serving at the request of the Corporation as a director, officer, partner, trustee, employee, or agent of another foreign or domestic corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, against liability asserted against or incurred by the individual in that capacity or arising from the individual’s status as a director, officer, employee, or agent, whether or not the Corporation would have power to indemnify the individual against the same liability under this Article IX.

9.10 Indemnification as a Witness. This Article IX does not limit a Corporation’s power to pay or reimburse expenses incurred by a director in connection with the director’s appearance as a witness in a proceeding at a time when the director has not been made a named defendant or respondent to the proceeding.

9.11 Interpretation. The provisions contained in this Article IX shall be interpreted and applied to provide indemnification to directors, officers, employees and agents of the Corporation to the fullest extent allowed by applicable law, as such law may be amended, interpreted and applied from time to time. The obligations of the Corporation under this Article IX to indemnify, and advance expenses to, a person who is or was a director or officer of the Corporation shall be considered a contract between the Corporation and such person, and no modification or repeal of any provision of this Article IX shall affect, to the detriment of such person, such obligations of the Corporation in connection with a claim based on any act or failure to act occurring before such modification or repeal.

ARTICLE X

BOOKS AND RECORDS

ARTICLE XIII

FORUM SELECTION

13.1 Forum for Adjudication of Certain Dispute. Unless the Corporation consents in writing to the selection of an alternative forum (an Alternative Forum Consent), the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a duty (including any fiduciary duty) owed by any current or former director, officer, stockholder, employee or agent of the Corporation to the

28

Corporation or the Corporation’s stockholders, (iii) any action asserting a claim against the Corporation or any current or former director, officer, stockholder, employee or agent of the Corporation arising out of or relating to any provision of the General Corporation Law of the State of Delaware, the Certificate of Incorporation or these Bylaws (each, as in effect from time to time), or (iv) any action asserting a claim against the Corporation or any current or former director, officer, stockholder, employee or agent of the Corporation governed by the internal affairs doctrine of the State of Delaware; provided, however, that, in the event that the Court of Chancery of the State of Delaware lacks subject matter jurisdiction over any such action or proceeding, the sole and exclusive forum for such action or proceeding shall be another state or federal court located within the State of Delaware, in each such case, unless the Court of Chancery (or such other state or federal court located within the State of Delaware, as applicable) has dismissed a prior action by the same plaintiff asserting the same claims because such court lacked personal jurisdiction over an indispensable party named as a defendant therein. If any action the subject matter of which is within the scope of the preceding sentence is filed in a court other than a court located within 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 located within the State of Delaware in connection with any action brought in any such court to enforce the preceding sentence and (y) having service of process made upon such stockholder in any such action by service upon such stockholder’s counsel in such Foreign Action as agent for such stockholder. Unless the Corporation gives an Alternative Forum Consent, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. Failure to enforce the foregoing provisions would cause the Corporation irreparable harm and the corporation shall be entitled to equitable relief, including injunctive relief and specific performance, to enforce the foregoing provisions. To the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of the corporation shall be deemed to have notice of and consented to the provisions of this Section 13.1. The existence of any prior Alternative Forum Consent shall not act as a waiver of the corporation’s ongoing consent right as set forth above in this Section 13.1 with respect to any current or future actions or claims.

Adopted and Effective May 9, 2023.
