Section 1. Authorized Shares. The total number of shares of all classes of capital stock which the Corporation shall have authority to issue is 550,000,000 shares, consisting of two classes as follows:

1. 50,000,000 shares of Preferred Stock, par value $0.001 per share (the “Preferred Stock”); and

2. 500,000,000 shares of Common Stock, par value $0.001 per share (the “Common Stock”).

The Preferred Stock and the Common Stock shall have the designations, rights, powers and preferences and the qualifications, restrictions and limitations thereof, if any, set forth below.

Section 2. Preferred Stock. The Board of Directors of the Corporation (the “Board of Directors”) is authorized, subject to limitations prescribed by law, to provide, by resolution or resolutions for the issuance of shares of Preferred Stock in one or more series, and with respect to each series, to establish the number of shares to be included in each such series, and to fix the voting powers (if any), designations, powers, preferences, and relative, participating, optional or other special rights, if any, of the shares of each such series, and any qualifications, limitations or restrictions thereof. The powers (including voting powers), preferences, and relative, participating, optional and other special rights of each series of Preferred Stock and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding. Subject to the rights of the holders of any series of Preferred Stock, the number of authorized shares of Preferred Stock may be increased or decreased (but

not below the number of shares thereof then outstanding) by the approval of the Board of Directors and by the affirmative vote of the holders of a majority in voting power of the outstanding shares of capital stock of the Corporation entitled to vote generally in an election of directors, without the separate vote of the holders of the Preferred Stock as a class, irrespective of the provisions of Section 242(b)(2) of the DGCL.

Section 3. Common Stock.

(a) Except as otherwise provided by the DGCL or this Third Amended and Restated Certificate of Incorporation (as it may be amended, the “Certificate of Incorporation”) and subject to the rights of holders of any series of Preferred Stock, all of the voting power of the stockholders of the Corporation shall be vested in the holders of the Common Stock. Each share of Common Stock shall entitle the holder thereof to one vote for each share held by such holder on all matters voted upon by the stockholders of the Corporation; provided, however, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate of Incorporation (including any certificate of designation relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Certificate of Incorporation (including any certificate of designation relating to any series of Preferred Stock) or pursuant to the DGCL.

(b) Except as otherwise required by law or expressly provided in this Certificate of Incorporation, each share of Common Stock shall have the same powers, rights and privileges and shall rank equally, share ratably and be identical in all respects as to all matters.

(c) Subject to the rights of the holders of Preferred Stock and to the other provisions of applicable law and this Certificate of Incorporation, holders of Common Stock shall be entitled to receive equally, on a per share basis, such dividends and other distributions in cash, securities or other property of the Corporation if, as and when declared thereon by the Board of Directors from time to time out of assets or funds of the Corporation legally available therefor.

(d) In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, after payment or provision for payment of the Corporation’s debts and any other payments required by law and amounts payable upon shares of Preferred Stock ranking senior to the shares of Common Stock upon such dissolution, liquidation or winding up, if any, the remaining net assets of the Corporation shall be distributed to the holders of shares of Common Stock and the holders of shares of any other class or series ranking equally with the shares of Common Stock upon such dissolution, liquidation or winding up, equally on a per share basis. A merger or consolidation of the Corporation with or into any other corporation or other entity, or a sale or conveyance of all or any part of the assets of the Corporation (which shall not in fact result in the liquidation of the Corporation and the distribution of assets to its stockholders) shall not be deemed to be a voluntary or involuntary liquidation or dissolution or winding up of the Corporation within the meaning of this Paragraph (d).

(e) No holder of shares of Common Stock shall be entitled to preemptive or subscription rights.

ARTICLE FIVE

Section 1. Board of Directors. Except as otherwise provided in this Certificate of Incorporation, the business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors.

Section 2. Number of Directors. Subject to any rights of the holders of any class or series of Preferred Stock to elect additional directors under specified circumstances or otherwise, the number of directors which shall constitute the Board of Directors shall be fixed from time to time exclusively by resolution of the Board.

Section 3. Classes of Directors. The directors of the Corporation, other than those who may be elected by the holders of any series of Preferred Stock, shall be divided into three classes, as nearly equal in number as possible, designated Class I, Class II and Class III.

Section 4. Election and Term of Office. The directors shall be elected by a plurality of the votes cast; provided that, whenever the holders of any class or series of capital stock of the Corporation are entitled to elect one or more directors pursuant to the provisions of this Certificate of Incorporation (including, but not limited to, any duly authorized certificate of designation), such directors shall be elected by a plurality of the votes cast by such holders. The term of office of the initial Class I directors shall expire at the first annual meeting of stockholders following the date the Common Stock is first publicly traded (the “IPO Date”), the term of office of the initial Class II directors shall expire at the second succeeding annual meeting of stockholders after the IPO Date and the term of office of the initial Class III directors shall expire at the third succeeding annual meeting of the stockholders after the IPO Date. For the purposes hereof, the Board of Directors may assign directors already in office to Class I, Class II and Class III, in accordance with the terms of that certain Director Nomination Agreement, dated on or about October 23, 2020 (as amended and/or restated or supplemented in accordance with its terms, the “Nomination Agreement”), by and among the Corporation and the investors named therein. At each annual meeting of stockholders after the IPO Date, directors elected to replace those of a class whose terms expire at such annual meeting shall be elected to hold office until the third succeeding annual meeting after their election and until their respective successors shall have been duly elected and qualified. 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. Nothing in this Certificate of Incorporation shall preclude a director from serving consecutive terms. Elections of directors need not be by written ballot unless the Bylaws of the Corporation (as amended and/or restated the “Bylaws”) shall so provide.

Section 5. Newly-Created Directorships and Vacancies. Subject to the rights of the holders of any series of Preferred Stock then outstanding and except as otherwise set forth in the Nomination Agreement, newly created directorships resulting from any increase in the authorized number of directors or any vacancies in the Board of Directors resulting from death, resignation, disqualification, removal from office or any other cause may be filled only by resolution of a majority of the directors then in office, although less than a quorum, or by a sole remaining director, and may not be filled in any other manner. A director elected or appointed to fill a vacancy shall serve for the unexpired term of his or her predecessor in office and until his or her successor is elected and qualified or until his or her earlier death, resignation or removal. A director elected or appointed to fill a position resulting from an increase in the number of directors shall hold office until the next election of the class for which such director shall have been elected or appointed and until his or her successor is elected and qualified, or until his or her earlier death, resignation or removal. No decrease in the authorized number of directors shall shorten the term of any incumbent director.

Section 6. Removal and Resignation of Directors. Subject to the rights of the holders of any series of Preferred Stock then outstanding and notwithstanding any other provision of this Certificate of Incorporation, (i) prior to the first date (the “Trigger Date”) on which Vista Foundation Fund II, L.P., Vista Foundation Fund II-A, L.P., VFF II FAF, L.P., Vista Foundation Fund II Executive, L.P., Vista Foundation Associates II, LLC and Merritt VI Aggregator, LLC (collectively, “Vista”) and their Affiliated Companies (as defined herein) cease to beneficially own in the aggregate (directly or indirectly) 40% or more of the voting power of the then outstanding shares of capital stock of the Corporation then entitled to vote generally in the election of directors (“Voting Stock”), directors may be removed with or without cause upon the affirmative vote of stockholders representing at least a majority of the voting power of the then outstanding shares of Voting Stock, voting together as a single class and (ii) on and after the Trigger Date, directors may only be removed for cause and only upon the affirmative vote of stockholders representing at least sixty-six and two-thirds percent (66²⁄₃%) of the voting power of the then outstanding shares of Voting Stock. Any director may resign at any time upon notice in writing or by electronic transmission to the Corporation.

Section 7. Rights of Holders of Preferred Stock. Notwithstanding the provisions of this ARTICLE FIVE, whenever the holders of one or more series of Preferred Stock shall have the right, voting separately or together by series, to elect directors at an annual or special meeting of stockholders, the election, term of office, filling of vacancies and other features of such directorship shall be subject to the rights of such series of Preferred Stock. During any period when the holders of any series of Preferred Stock, voting separately as a series or together with one or more series, have the right to elect additional directors, then upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of directors of the Corporation shall automatically be increased by such specified number of directors, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions, and (ii) each such additional director shall serve until such director’s successor shall have been duly elected and qualified, or until such director’s right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his or her earlier death, resignation, disqualification or removal. Except as otherwise provided by the Board of Directors in the resolution or resolutions establishing such series, whenever the holders of any series of Preferred Stock having such right

to elect additional directors are divested of such right pursuant to the provisions of such stock, the terms of office of all such additional directors elected by the holders of such stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate (in which case each such director thereupon shall cease to be qualified as, and shall cease to be, a director) and the total authorized number of directors of the Corporation shall automatically be reduced accordingly.

Section 8. Advance Notice. Advance notice of stockholder nominations for the election of directors and of business to be brought by stockholders before any meeting of the stockholders of the Corporation shall be given in the manner provided in the Bylaws.

ARTICLE SIX

Section 1. Limitation of Liability.

(a) To the fullest extent permitted by the DGCL as it now exists or may hereafter be amended (but, in the case of any such amendment, only to the extent such amendment permits the Corporation to provide broader exculpation than permitted prior thereto), no director of the Corporation shall be liable to the Corporation or its stockholders for monetary damages arising from a breach of fiduciary duty as a director.

(b) Any amendment, repeal or modification of the foregoing paragraph shall not adversely affect any right or protection of a director of the Corporation existing at the time of such amendment, repeal or modification with respect to any act, omission or other matter occurring prior to such amendment, repeal or modification.

ARTICLE SEVEN

Section 1. Action by Written Consent. Prior to the first date (the “Stockholder Consent Trigger Date”) on which Vista and its Affiliated Companies (as defined herein) cease to beneficially own in the aggregate (directly or indirectly) at least 35% of the voting power of the then outstanding Voting Stock, any action which is required or permitted to be taken by the Corporation’s stockholders may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of the Corporation’s stock entitled to vote thereon were present and voted. From and after the Stockholder Consent Trigger Date, any action required or permitted to be taken by the Corporation’s stockholders may be taken only at a duly called annual or special meeting of the Corporation’s stockholders and the power of stockholders to consent in writing without a meeting is specifically denied; provided, however, that any action required or permitted to be taken by the holders of Preferred Stock, voting separately as a series or separately as a class with one or more other such series, may be taken without a meeting, without prior notice and without a vote, to the extent expressly so provided the resolutions creating such series of Preferred Stock.

Section 2. Special Meetings of Stockholders. Subject to the rights of the holders of any series of Preferred Stock then outstanding and to the requirements of applicable law, special meetings of stockholders of the Corporation may be called only (i) by or at the direction of the Board of Directors or the Chairman of the Board of Directors pursuant to a written resolution adopted by the affirmative vote of the majority of the total number of directors that the Corporation would have if there were no vacancies or (ii) prior to the Stockholder Consent Trigger Date, by the Chairman of the Board of Directors at the written request of the holders of a majority of the voting power of the then outstanding shares of Voting Stock in the manner provided for in the Bylaws. Any business transacted at any special meeting of stockholders shall be limited to the purpose or purposes stated in the notice of the meeting.

ARTICLE EIGHT

Section 1. Certain Acknowledgments. In recognition and anticipation that (i) certain of the directors, partners, principals, officers, members, managers and/or employees of Vista or its Affiliated Companies (as defined below) may serve as directors or officers of the Corporation and (ii) Vista and its Affiliated Companies engage and may continue to engage in the same or similar activities or related lines of business as those in which the Corporation, directly or indirectly, may engage and/or other business activities that overlap with or compete with those in which the Corporation, directly or indirectly, may engage, and (iii) that the Corporation and its Affiliated Companies may engage in material business transactions with Vista and its Affiliated Companies, and that the Corporation is expected to benefit therefrom, the provisions of this ARTICLE EIGHT are set forth to regulate and define to the fullest extent permitted by law the conduct of certain affairs of the Corporation as they may involve Vista and/or its Affiliated Companies and/or their respective directors, partners, principals, officers, members, managers and/or employees, including any of the foregoing who serve as officers or directors of the Corporation (collectively, the “Exempted Persons”), and the powers, rights, duties and liabilities of the Corporation and its officers, directors and stockholders in connection therewith. As used in this Certificate of Incorporation, “Affiliated Companies” shall mean (a) in respect of Vista, any entity that controls, is controlled by or under common control with Vista (other than the Corporation and any company that is controlled by the Corporation) and any investment funds managed by Vista and (b) in respect of the Corporation, any company controlled by the Corporation.

Section 2. Competition and Corporate Opportunities. To the fullest extent permitted by applicable law, none of the Exempted Persons shall have any fiduciary duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as the Corporation or any of its Affiliated Companies, and no Exempted Person shall be liable to the Corporation or its stockholders for breach of any fiduciary duty solely by reason of any such activities of Vista, its Affiliated Companies or such Exempted Person. To the fullest extent permitted by applicable law, the Corporation, on behalf of itself and its Affiliated Companies, renounces any interest or expectancy of the Corporation and its Affiliated Companies in, or in being offered an opportunity to participate in, business opportunities that are from time to time presented to the Exempted Persons, even if the opportunity is one that the Corporation or its Affiliated Companies might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each Exempted Person shall have no duty to communicate or offer such business opportunity to the Corporation or its Affiliated Companies and, to the fullest extent permitted by applicable law, shall not be liable to the Corporation, any of its Affiliated Companies or its stockholders for breach of any fiduciary or other duty, as a director, officer or stockholder of the Corporation solely, by reason of the fact that Vista, its

Affiliated Companies or any such Exempted Person pursues or acquires such business opportunity, sells, assigns, transfers or directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to the Corporation or any of its Affiliated Companies. Notwithstanding anything to the contrary in this Section 2, the Corporation does not renounce any interest or expectancy it may have in any business opportunity that is expressly offered to any Exempted Person solely in his or her capacity as a director or officer of the Corporation, and not in any other capacity.

Section 3. Certain Matters Deemed Not Corporate Opportunities. In addition to and notwithstanding the foregoing provisions of this ARTICLE EIGHT, a corporate opportunity shall not be deemed to belong to the Corporation if it is a business opportunity the Corporation is not financially able or contractually permitted or legally able to undertake, or that is, from its nature, not in the line of the Corporation’s business or is of no practical advantage to it or that is one in which the Corporation has no interest or reasonable expectancy.

Section 4. Amendment of this Article. Notwithstanding anything to the contrary elsewhere contained in this Certificate of Incorporation, subject to the rights of the holders of any series of Preferred Stock then outstanding, and in addition to any vote required by applicable law, the affirmative vote of the holders of at least eighty percent (80%) of the voting power of the then outstanding shares of Voting Stock, voting together as a single class, shall be required to alter, amend or repeal, or to adopt any provision inconsistent with, this ARTICLE EIGHT; provided however, that, to the fullest extent permitted by law, neither the alteration, amendment or repeal of this ARTICLE EIGHT nor the adoption of any provision of this Certificate of Incorporation inconsistent with this ARTICLE EIGHT shall apply to or have any effect on the liability or alleged liability of any Exempted Person for or with respect to any activities or opportunities which such Exempted Person becomes aware prior to such alteration, amendment, repeal or adoption.

Section 5. Deemed Notice. Any person or entity purchasing or otherwise acquiring or holding any interest in any shares of the Corporation shall be deemed to have notice of and to have consented to the provisions of this ARTICLE EIGHT.

(c) at or subsequent to such time, the Business Combination is approved by the Board of Directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least sixty-six and two-thirds percent (66²⁄₃%) of the outstanding Voting Stock which is not owned by such Interested Stockholder.

Section 3. Exceptions to Prohibition on Interested Stockholder Transactions. The restrictions contained in this ARTICLE NINE shall not apply if:

Notwithstanding anything in this ARTICLE NINE to the contrary, the term “Interested Stockholder” shall not include: (x) Vista or any of its Affiliated Companies, or any other Person with whom any of the foregoing are acting as a group or in concert for the purpose of acquiring, holding, voting or disposing of shares of Stock of the Corporation, (y) any Person who would otherwise be an Interested Stockholder either in connection with or because of a transfer, sale, assignment, conveyance, hypothecation, encumbrance, or other disposition of five percent (5%) or more of the outstanding Voting Stock of the Corporation (in one transaction or a series of transactions) by Vista or any of its Affiliates or Associates to such Person; provided, however, that such Person was not an Interested Stockholder prior to such transfer, sale, assignment, conveyance, hypothecation, encumbrance, or other disposition; or (z) any Person whose ownership of shares in excess of the fifteen percent (15%) limitation set forth herein is the result of action taken solely by the Corporation, provided that, for purposes of this clause (z) only, such Person shall be an Interested Stockholder if thereafter such Person acquires additional shares of Voting Stock of the Corporation, except as a result of further action by the Corporation not caused, directly or indirectly, by such Person; provided, that, for the purpose of determining whether a Person is an Interested Stockholder, the Voting Stock of the Corporation deemed to be outstanding shall include Stock deemed to be owned by the Person through application of this definition of “owned” but shall not include any other unissued Stock of the Corporation which may be issuable pursuant to any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or otherwise;
