or (y) the 15th day following the day on which public announcement of the date of such meeting is first made by the corporation.

(i) set forth, as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (A) the name and address of such stockholder, as they appear on the corporation's books, and of such beneficial owner, if any, (B) the class or series and number of shares of the corporation that are, directly or indirectly, owned beneficially and of record by such stockholder and such beneficial owner, if any, as of the date of such notice (which information shall be supplemented by such stockholder and beneficial owner not later than 10 days after the record date for the meeting to disclose such ownership as of the record date), and (C) any other information relating to such stockholder and beneficial owner, if any, that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for, as applicable, the proposal and/or for the election of directors in a contested election pursuant to Section 14 of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”);

(ii) if the notice relates to any business other than the nomination of a director that the stockholder proposes to bring before the meeting, set forth (A) a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest of such stockholder and beneficial owner, if any, in such business, and (B) a description of all agreements, arrangements and understandings between such stockholder and beneficial owner and any other person or persons (including their names) in connection with the proposal of such business by such stockholder;

(iii) set forth, as to each person, if any, whom the stockholder proposes to nominate for election or reelection as a director (A) all information relating to such person that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors in a contested election pursuant to Section 14 of the Exchange Act (including such person's written consent to being named in the proxy statement as a nominee and to serving as a director if elected) and (B) a description of all direct and indirect compensation and other monetary agreements, arrangements and understandings during the past three years, and any other relationships, between or among such stockholder and beneficial owner, if any, and their respective affiliates and associates, or others acting in concert therewith, on the one hand, and each proposed nominee, and their respective affiliates and associates, or others acting in concert therewith, on the other hand, including, without limitation all information that would be required to be disclosed pursuant to Rule 404 promulgated under Regulation S-K if the stockholder making the nomination and any beneficial owner on whose behalf the nomination is made, if any, or any affiliate or associate thereof or person acting in concert therewith, were the “registrant” for purposes of such rule and the nominee were a director or executive officer of such registrant; and

(iv) with respect to each nominee for election or reelection to the Board of Directors, include the completed and signed questionnaire, representation, and agreement required by Section 2.13(d) of this Article II below. The corporation may require any proposed nominee to furnish such other information as may reasonably be required by the corporation to determine the

Docusign Envelope ID: E0A90D4B-0F74-4568-9560-B59E5BCE8C46

eligibility of such proposed nominee to serve as an independent director of the corporation or that could be material to a reasonable stockholder’s understanding of the independence, or lack thereof, of such nominee.

(c) Notwithstanding anything in the second sentence of paragraph (b) of this Section 2.13 of this Article II to the contrary, in the event that the number of directors to be elected to the Board of Directors of the corporation at an annual meeting is increased, whether by increase in the size of the Board of Directors, or by any vacancy in the Board of Directors to be filled at such annual meeting, and there is no public announcement by the corporation naming all of the nominees for directors or specifying the size of the increased Board of Directors at least 75 days prior to the first anniversary of the preceding year’s annual meeting, a stockholder’s notice required by this Section 2.13 of this Article II shall also be considered timely, but only with respect to nominees for any such vacant positions and for any new positions created by such increase, if it shall be delivered to the secretary at the principal executive offices of the corporation not later than the close of business on the 10th day following the day on which such public announcement is first made by the corporation.

(d) To be eligible to be a nominee for election or reelection as a director of the corporation, a person must deliver (in accordance with the time periods prescribed for delivery of notice under paragraphs (b) and (c) above) to the secretary of the corporation at the principal executive offices of the corporation a completed, written and signed questionnaire (in the form customarily used by the corporation for its directors) with respect to the background and qualification of such person and the background of any other person or entity on whose behalf the nomination is being made (which questionnaire shall be provided by the secretary upon written request) and a written representation and agreement (in the form provided by the secretary upon written request) that such person:

(i) is not and will not become a party to (A) any agreement, arrangement or understanding with, and has not given any commitment or assurance to, any person or entity as to how such person, if elected as a director of the corporation, will act or vote on any issue or question (a “Voting Commitment”) that has not been disclosed to the corporation or (B) any Voting Commitment that could limit or interfere with such persons' ability to comply, if elected as a director of the corporation, with such person's fiduciary duties under applicable law;

(ii) is not and will not become a party to any agreement, arrangement or understanding with any person or entity other than the corporation with respect to any direct or indirect compensation, reimbursement or indemnification in connection with service or action as a director that has not been disclosed therein; and

(iii) in such person’s individual capacity and on behalf of any person or entity on whose behalf the nomination is being made, would be in compliance, if elected as a director of the corporation, and will comply with all applicable publicly disclosed corporate governance, conflict of interest, confidentiality, and stock ownership and trading policies and guidelines of the corporation.

Notwithstanding the foregoing provisions of this Section 2.13 of this Article II, a stockholder shall also comply with all applicable requirements of the Exchange Act, and the rules and regulations

Docusign Envelope ID: E0A90D4B-0F74-4568-9560-B59E5BCE8C46

thereunder with respect to the matters set forth in this Section 2.13 of this Article II, and nothing in this Section 2.13 of this Article II shall be deemed to affect any rights of stockholders to request inclusion of proposals in the corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act (or any successor provision thereof) and, to the extent required by such rule, have such proposals considered and voted on at an annual meeting.

Section 14. Places of Meetings. Meetings of stockholders shall be held at any place designated by the Board of Directors (a) within or outside the State of Delaware, or (b) by means of remote communication (a “Virtual Meeting”), in each case as may be determined by the Board of Directors from time to time. In the absence of any such designation, stockholders’ meetings shall be held at the registered office of the corporation or the Board of Directors may, in its sole discretion, determine that the meeting shall not be held at any place, but will instead be held solely by means of remote communication as provided under Section 211 of the Delaware General Corporation Law (“DGCL”).

ARTICLE III. DIRECTORS

Section 1. Powers. The business of the corporation shall be managed by or under the direction of its Board of Directors, which may exercise all such powers of the corporation and do all such lawful acts and things as are not by applicable law or by the Certificate of Incorporation or by these Amended and Restated Bylaws (these “Bylaws”) directed or required to be exercised or done by the stockholders.

Section 2. Number; Election; Tenure and Qualification. The number of directors which shall constitute the whole board shall be fixed from time to time by resolution of the Board of Directors; provided however, that the number of directors constituting the whole board shall be not less than three (3) members and not more than seven (7) members. With the exception of the first Board of Directors, which shall be appointed by the incorporator, and except as provided in the corporation’s Certificate of Incorporation or in Section 3 of this Article III, the directors shall be elected at the annual meeting of the stockholders by a majority vote of the shares represented in person or by proxy and each director elected shall hold office until his successor is elected and qualified unless he shall resign, become disqualified, disabled, or otherwise removed. Directors need not be stockholders. Each director shall hold office until the annual meeting of stockholders for the year in which such director’s term expires and a successor is duly elected and qualified or until his or her earlier death, resignation or removal.

Section 3. Vacancies and Newly Created Directorships. Unless otherwise provided in the Certificate of Incorporation, vacancies and newly-created directorships resulting from any increase in the authorized number of directors may be filled by a majority of the directors then in office, though less than a quorum, or by a sole remaining director, except that any vacancy created by the removal of a director by the stockholders for cause shall be filled, in addition to any other vote otherwise required by law, only by vote of the holders of at least a majority of the outstanding shares of common stock, par value of $0.00001 per share, of the corporation entitled to vote with respect thereto, present in person and represented by proxy, voting together as a single class, at a meeting of the stockholders. The directors so chosen shall serve until the next annual election and until their successors are duly elected and shall qualify, unless sooner displaced. If there are no

Docusign Envelope ID: E0A90D4B-0F74-4568-9560-B59E5BCE8C46

directors in office, then an election of directors may be held in the manner provided by applicable law. If, at the time of filling any vacancy or any newly created directorship, the directors then in office shall constitute less than a majority of the whole board (as constituted immediately prior to any such increase), the Court of Chancery may, upon application of any stockholder or stockholders holding at least ten percent of the total number of shares at the time outstanding having the right to vote for such directors, summarily order an election to be held to fill any such vacancies or newly created directorships, or to replace the directors chosen by the directors then in office.

Section 4. Location of Meetings. The Board of Directors of the corporation may hold meetings, both regular and special, either within or without the State of Delaware.

Section 5. Meeting of Newly Elected Board of Directors. The first meeting of each newly elected Board of Directors shall be held immediately following the annual meeting of stockholders and no notice of such meeting shall be necessary to the newly elected directors in order legally to constitute the meeting, provided a quorum shall be present. In the event such meeting is not held at such time, the meeting may be held at such time and place as shall be specified in a notice given as hereinafter provided for special meetings of the Board of Directors, or as shall be specified in a written waiver signed by all of the directors.

Section 6. Regular Meetings. Regular meetings of the Board of Directors may be held without notice at such time and at such place as shall from time to time be determined by the Board of Directors; provided that any director who is absent when such a determination is made shall be given notice of such location; and provided further that, in the ordinary course, the regular meetings of the Board of Directors shall be held in the United States.

Section 7. Special Meetings. Special meetings of the Board of Directors may be called by the Chief Executive Officer on two days’ notice to each director by mail, overnight courier service or facsimile; special meetings shall be called by the Chief Executive Officer or Secretary in a like manner and on like notice on the written request of two directors unless the Board of Directors consists of only one director, in which case special meetings shall be called by the Chief Executive Officer or Secretary in a like manner and on like notice on the written request of the sole director. Notice may be waived in accordance with Section 229 of the General Corporation Law of the State of Delaware.

Section 8. Quorum and Action at Meetings. At all meetings of the Board of Directors, a majority of the directors then in office shall constitute a quorum for the transaction of business, and the act of a majority of the directors present at any meeting at which there is a quorum shall be the act of the Board of Directors, except as may be otherwise specifically provided by statute or by the Certificate of Incorporation. If a quorum shall not be present at any meeting of the Board of Directors, the directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

Section 9. Action Without a Meeting. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting, if all members of

Docusign Envelope ID: E0A90D4B-0F74-4568-9560-B59E5BCE8C46

the Board of Directors or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board of Directors or committee.

Section 10. Telephonic Meeting. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, members of the Board of Directors, or any committee designated by the Board of Directors, may participate in a meeting of the Board of Directors, or any committee, by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at the meeting.

Section 11. Committees. The Board of Directors may, by resolution passed by a majority of the whole board, designate one or more committees, each committee to consist of one or more of the directors of the corporation. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of any such absent or disqualified member.

Section 12. Committee Authority. Any such committee, to the extent provided in the resolution of the Board of Directors, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and affairs of the corporation, and may authorize the seal of the corporation to be affixed to all papers which may require it; but no such committee shall have the power or authority in reference to (a) approving, adopting or recommending to the stockholders, any action or matter expressly required by the General Corporation Law of the State of Delaware to be submitted to stockholders for approval, or (b) adopting, amending or repealing any Bylaw of the corporation. Such committee or committees shall have such name or names as may be determined from time to time by resolution adopted by the Board of Directors.

Section 13. Committee Minutes. Each committee shall keep regular minutes of its meetings and report the same to the Board of Directors when required to do so by the Board of Directors.

Section 14. Directors Compensation. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, the stockholders of the corporation shall have the authority to fix the total amount of compensation that will be paid to the directors, and the Board of Directors shall have the authority to allocate such total amount amongst the directors. The directors may be paid their expenses, if any, of attendance at each meeting of the Board of Directors and may be paid a fixed sum for attendance at each meeting of the Board of Directors or a stated salary as director. No such payment shall preclude any director from serving the corporation in any other capacity and receiving compensation therefor. Members of special or standing committees may be allowed like compensation for attending committee meetings.

Section 15. Resignation. Any director or officer of the corporation may resign at any time. Each such resignation shall be made in writing and shall take effect at the time specified

Docusign Envelope ID: E0A90D4B-0F74-4568-9560-B59E5BCE8C46

therein, or, if no time is specified, at the time of its receipt by the Board of Directors, the Chief Executive Officer or the Secretary. The acceptance of a resignation shall not be necessary to make it effective unless expressly so provided in the resignation.

Section 16. Removal. Unless otherwise restricted by statute, by the Certificate of Incorporation or by these Bylaws, any director or the entire Board of Directors may be removed, only with cause and only by an affirmative vote of the holders of at least a majority of the voting power of the outstanding shares of capital stock of the corporation entitled to vote generally in the election of directors, present in person or represented by proxy, voting together as a single class, at a meeting of the stockholders called for that purpose. At least thirty (30) days prior to any meeting of stockholders at which it is proposed that any director be removed from office, written notice of such proposed removal shall be sent to the director whose removal will be considered at the meeting. For purposes of this Section 16 of this Article III, “cause” with respect to the removal of any director, shall mean only (i) conviction of a felony, (ii) declaration of unsound mind by order of a court, (iii) gross dereliction of duty, (iv) commission of any act involving moral turpitude, or (v) commission of an act that constitutes intentional misconduct or a knowing violation of law if such action in either event results both in an improper substantial personal benefit to such director and a material injury to the corporation. No reduction of the authorized number of directors shall have the effect of removing any director prior to the expiration of such director’s term of office.

ARTICLE IV. NOTICES

Section 1. Notice to Directors and Stockholders. Whenever, under the provisions of the statutes or of the Certificate of Incorporation or of these Bylaws, notice is required to be given to any director or stockholder, it shall not be construed to mean personal notice, but such notice may be (i) given in writing, by mail, addressed to such director or stockholder, at his address as it appears on the records of the corporation, with postage thereon prepaid, and such notice shall be deemed to be given at the time when the same shall be deposited in the United States mail or (ii) sent by electronic mail or via an electronic portal, addressed to such director or stockholder, at his address, telephone number, or electronic mail address as it appears on the records of the corporation, and such notice shall be deemed to given when sent, if sent by electronic mail or electronic portal during the director or stockholder’s normal business hours, and if not sent during normal business hours, then on the director or stockholder’s next business day. An affidavit of the Secretary or an Assistant Secretary or of the transfer agent of the corporation that the notice has been given shall in the absence of fraud, be prima facie evidence of the facts stated therein. Notice to directors may also be given by telephone (with confirmation of receipt).

Section 2. Notice by Electronic Transmission. Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the corporation under any provision of the DGCL, the Certificate of Incorporation, or these Bylaws shall be effective if given by a form of electronic transmission consented to by the stockholder to whom the notice is given. A corporation may give a notice by electronic mail without obtaining the consent noted herein. Any such consent shall be revocable by the stockholder by written notice or electronic transmission to the corporation. Notwithstanding the foregoing, a notice may not be given by an electronic transmission from and after the time that:

Docusign Envelope ID: E0A90D4B-0F74-4568-9560-B59E5BCE8C46

(a) the corporation is unable to deliver by electronic transmission two consecutive notices given by the corporation; and

(b) such inability becomes known to the Secretary or an Assistant Secretary of the corporation or to the transfer agent, or other person responsible for the giving of notice.

However, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action.

Any notice given pursuant to the preceding paragraph shall be deemed given:

(1) if by a posting on an electronic network together with separate notice to the stockholder of such specific posting, upon the later of (A) such posting and (B) the giving of such separate notice; and

(2) if by any other form of electronic transmission, when

directed to the stockholder.

An affidavit of the Secretary or an Assistant Secretary or of the transfer agent or other agent of the corporation that the notice has been given by a form of electronic transmission shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

An “electronic transmission” means any form of communication, not directly involving the physical transmission of paper, that creates a record that may be retained, retrieved, and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such a recipient through an automated process.

Notice by a form of electronic transmission shall not apply to Sections 164, 296, 311, 312, or 324 of the DGCL.

Section 3. Waiver. Whenever any notice is required to be given under the provisions of the statutes or of the Certificate of Incorporation or of these Bylaws, a waiver thereof in writing, signed by the person or persons entitled to said notice, whether before or after the time stated therein, shall be deemed equivalent thereto. The written waiver need not specify the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders, directors, or members of a committee of directors. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting 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. Attendance at the meeting is not a waiver of any right to object to the consideration of matters required by the General Corporation Law of the State of Delaware to be included in the notice of the meeting but not so included, if such objection is expressly made at the meeting.
