CAPITALIZATION

Section 4.1 Authorized Capital Stock. The total number of shares of all classes of capital stock which the Corporation is authorized to issue is 101,000,000 shares, consisting of (a) 100,000,000 shares of common stock, par value $0.0001 per share (the “Common Stock”) and (b) 1,000,000 shares of preferred stock, par value $0.0001 per share (the “Preferred Stock”).

Effective upon the filing of this Amended and Restated Certificate with the Secretary of State of the State of Delaware, a 1.2-for-1 forward stock split for each share of Common Stock outstanding or held in treasury immediately prior to such time shall automatically and without any action of the part of the holders thereof occur (the “Forward Stock Split”). The par value of the Common Stock shall remain $0.0001 per share. This conversion shall apply to all shares of Common Stock. No fractional shares of Common Stock shall be issued upon the Forward Stock Split or otherwise. In lieu of any fractional shares of Common Stock to which the stockholder would otherwise be entitled upon the Forward Stock Split, the Corporation shall pay cash equal to such fraction multiplied by the then fair market value of the Common Stock as determined by the Board.

All certificates representing shares of Common Stock outstanding immediately prior to the filing of this Amended and Restated Certificate shall immediately after the filing of this Amended and Restated Certificate represent instead the number of shares of Common Stock as provided above. Notwithstanding the foregoing, any holder of Common Stock may (but shall not be required to) surrender his, her or its stock certificate or certificates to the corporation, and upon such surrender the Corporation will issue a certificate for the correct number of shares of Common Stock to which the holder is entitled under the provisions of this Forward Stock Split. Shares of Common Stock that were outstanding prior to the filing of this Amended and Restated Certificate, and that are not outstanding after and as a result of the filing of this Amended and Restated Certificate, shall resume the status of authorized but unissued shares of Common Stock.

Section 4.2 Preferred Stock. Subject to Article IX of this Amended and Restated Certificate, the Board of Directors of the Corporation (the “Board”) is hereby expressly authorized to provide out of the unissued shares of the Preferred Stock for one or more series of Preferred Stock and to establish from time to time the number of shares to be included in each such series and to fix the voting rights, if any, designations, powers, preferences and relative, participating, optional, special and other rights, if any, of each such series and any qualifications, limitations and restrictions thereof, as shall be stated in the resolution or resolutions adopted by the Board providing for the issuance of such series and included in a certificate of designation (a “Preferred Stock Designation”) filed pursuant to the DGCL, and the Board is hereby expressly vested with the authority to the full extent provided by law, now or hereafter, to adopt any such resolution or resolutions.

Section 4.3 Common Stock.

(i) Except as otherwise required by law or this Amended and Restated Certificate (including any Preferred Stock Designation), the holders of the shares of Common Stock shall exclusively possess all voting power with respect to the Corporation.

(ii) Except as otherwise required by law or this Amended and Restated Certificate (including any Preferred Stock Designation), the holders of shares of Common Stock shall be entitled to one vote for each such share on each matter properly submitted to the stockholders of the Corporation on which the holders of the shares of Common Stock are entitled to vote.

(iii) Except as otherwise required by law or this Amended and Restated Certificate (including any Preferred Stock Designation), at any annual or special meeting of the stockholders of the Corporation, the holders of the shares of Common Stock shall have the exclusive right to vote for the election of directors and on all other matters properly submitted to a vote of the stockholders of the Corporation. Notwithstanding the foregoing, except as otherwise required by law or this Amended and Restated Certificate (including any Preferred Stock Designation), the holders of the shares of Common Stock shall not be entitled to vote on any amendment to this Amended and Restated Certificate (including any amendment to any Preferred Stock Designation) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series of Preferred Stock are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Amended and Restated Certificate (including any Preferred Stock Designation) or the DGCL.

(c) Liquidation, Dissolution or Winding Up of the Corporation. Subject to applicable law, the rights, if any, of the holders of any outstanding series of the Preferred Stock and the provisions of Article IX hereof, in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, after payment or provision for payment of the debts and other liabilities of the Corporation, the holders of the shares of Common Stock shall be entitled to receive all the remaining assets of the Corporation available for distribution to its stockholders, ratably in proportion to the number of shares of Common Stock held by them.

Section 4.4 Rights and Options. The Corporation has the authority to create and issue rights, warrants and options entitling the holders thereof to acquire from the Corporation any shares of its capital stock of any class or classes, with such rights, warrants and options to be evidenced by or in instrument(s) approved by the Board. The Board is empowered to set the exercise price, duration, times for exercise and other terms and conditions of such rights, warrants or options; provided, however, that the consideration to be received for any shares of capital stock issuable upon exercise thereof may not be less than the par value thereof.

ARTICLE VIII

LIMITED LIABILITY; INDEMNIFICATION

Section 8.1 Limitation of Director Liability. A director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or may hereafter be amended unless a director violated his or her duty of loyalty to the Corporation or its stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived improper personal benefit from his or her actions as a director. Any amendment, modification or repeal of the foregoing sentence shall not adversely affect any right or protection of a director of the Corporation hereunder in respect of any act or omission occurring prior to the time of such amendment, modification or repeal.

Section 8.2 Indemnification and Advancement of Expenses.

(a) To the fullest extent permitted by applicable law, as the same exists or may hereafter be amended, the Corporation shall indemnify and hold harmless each person who is or was made a party or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”) by reason of the fact that he or she 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 nonprofit entity, including service with respect to an employee benefit plan (an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent, or in any other capacity while serving as a director, officer, employee or agent, against all liability and loss suffered and expenses (including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred by such indemnitee in connection with such proceeding. The Corporation shall to the fullest extent not prohibited by applicable law pay the expenses (including attorneys’ fees) incurred by an indemnitee in defending or otherwise participating in any proceeding in advance of its final disposition; provided, however, that, to the extent required by applicable law, such payment of expenses in advance of the final disposition of the proceeding shall be made only upon receipt of an undertaking, by or on behalf of the indemnitee, to repay all amounts so advanced if it shall ultimately be determined that the indemnitee is not entitled to be indemnified under this Section 8.2 or otherwise. The rights to indemnification and advancement of expenses conferred by this Section 8.2 shall be contract rights and such rights shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators. Notwithstanding the foregoing provisions of this Section 8.2(a), except for proceedings to enforce rights to indemnification and advancement of expenses, the Corporation shall indemnify and advance expenses to an indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board.

(b) The rights to indemnification and advancement of expenses conferred on any indemnitee by this Section 8.2 shall not be exclusive of any other rights that any indemnitee may have or hereafter acquire under law, this Amended and Restated Certificate, the Bylaws, an agreement, vote of stockholders or disinterested directors, or otherwise.

(c) Any repeal or amendment of this Section 8.2 by the stockholders of the Corporation or by changes in law, or the adoption of any other provision of this Amended and Restated Certificate inconsistent with this Section 8.2, shall, unless otherwise required by law, be prospective only (except to the extent such amendment or change in law permits the Corporation to provide broader indemnification rights on a retroactive basis than permitted prior thereto), and shall not in any way diminish or adversely affect any right or protection existing at the time of such repeal or amendment or adoption of such inconsistent provision in respect of any proceeding (regardless of when such proceeding is first threatened, commenced or completed) arising out of, or related to, any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision.

(d) This Section 8.2 shall not limit the right of the Corporation, to the extent and in the manner authorized or permitted by law, to indemnify and to advance expenses to persons other than indemnitees.

ARTICLE IX

BUSINESS COMBINATION REQUIREMENTS; EXISTENCE

Section 9.1 General.

(a) The provisions of this Article IX shall apply during the period commencing upon the effectiveness of this Amended and Restated Certificate and terminating upon the consummation of the Corporation’s initial Business Combination and no amendment to this Article IX shall be effective prior to the consummation of the initial Business Combination unless approved by the affirmative vote of the holders of at least sixty-five percent (65%) of all then outstanding shares of the Common Stock.

(b) Immediately after the Offering, a certain amount of the net offering proceeds received by the Corporation in the Offering (including the proceeds of any exercise of the underwriters’ over-allotment option) and certain other amounts specified in the Corporation’s registration statement on Form S-1, as initially filed with the Securities and Exchange Commission on January 21, 2021, as amended (the “Registration Statement”), shall be deposited in a trust account (the “Trust Account”), established for the benefit of the Public Stockholders (as defined below) pursuant to a trust agreement described in the Registration Statement. Except for the payment of deferred underwriting commissions and the withdrawal of interest to pay taxes, none of the funds held in the Trust Account (including the interest earned on the funds held in the Trust

Account) will be released from the Trust Account until the earliest to occur of (i) the completion of the initial Business Combination, (ii) the redemption of 100% of the Offering Shares (as defined below) if the Corporation is unable to complete its initial Business Combination within 24 months from the closing of the Offering, and (iii) the redemption of shares in connection with a vote seeking to amend any provisions of the Amended and Restated Certificate relating to the Corporation’s pre-initial Business Combination activity and related stockholders’ rights (as described in Section 9.7). Holders of shares of Common Stock included as part of the units sold in the Offering (the “Offering Shares”) (whether such Offering Shares were purchased in the Offering or in the secondary market following the Offering and whether or not such holders are Founders (as such term is defined in the Registration Statement), officers or directors of the Corporation, or affiliates of any of the foregoing) are referred to herein as “Public Stockholders.”

Section 9.2 Redemption Rights.

(a) Prior to the consummation of the initial Business Combination, the Corporation shall provide all holders of Offering Shares with the opportunity to have their Offering Shares redeemed upon the consummation of the initial Business Combination pursuant to, and subject to the limitations of, Sections 9.2(b) and 9.2(c) (such rights of such holders to have their Offering Shares redeemed pursuant to such Sections, the “Redemption Rights”) hereof for cash equal to the applicable redemption price per share determined in accordance with Section 9.2(b) hereof (the “Redemption Price”); provided, however, that the Corporation shall not redeem Offering Shares to the extent that such redemption would result in the Corporation’s failure to have net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (or any successor rule)) of at least $5,000,001 or any greater net tangible asset or cash requirement which may be contained in the agreement relating to the initial Business Combination upon consummation of the initial Business Combination (such limitation hereinafter called the “Redemption Limitation”). Notwithstanding anything to the contrary contained in this Amended and Restated Certificate, there shall be no Redemption Rights or liquidating distributions with respect to any rights or warrants issued pursuant to the Offering.

(b) If the Corporation offers to redeem the Offering Shares other than in conjunction with a stockholder vote on an initial Business Combination with a proxy solicitation pursuant to Regulation 14A of the Exchange Act (or any successor rules or regulations) and filing proxy materials with the Securities and Exchange Commission (the “SEC”), the Corporation shall offer to redeem the Offering Shares upon the consummation of the initial Business Combination, subject to lawfully available funds therefor, in accordance with the provisions of Section 9.2(a) hereof pursuant to a tender offer in accordance with Rule 13e-4 and Regulation 14E of the Exchange Act (or any successor rule or regulation) (such rules and regulations hereinafter called the “Tender Offer Rules”) which it shall commence prior to the consummation of the initial Business Combination and shall file tender offer documents with the SEC prior to the consummation of the initial Business Combination that contain substantially the same financial and other information about the initial Business Combination and the Redemption Rights as is required under Regulation 14A of the Exchange Act (or any successor rule or regulation) (such rules and regulations hereinafter called the “Proxy Solicitation Rules”), even if such information is not required under the

6

Tender Offer Rules; provided, however, that if a stockholder vote is required by law to approve the proposed initial Business Combination, or the Corporation decides to submit the proposed initial Business Combination to the stockholders for their approval for business or other legal reasons, the Corporation shall offer to redeem the Offering Shares, subject to lawfully available funds therefor, in accordance with the provisions of Section 9.2(a) hereof in conjunction with a proxy solicitation pursuant to the Proxy Solicitation Rules (and not the Tender Offer Rules) at a price per share equal to the Redemption Price calculated in accordance with the following provisions of this Section 9.2(b). In the event that the Corporation offers to redeem the Offering Shares pursuant to a tender offer in accordance with the Tender Offer Rules, the Redemption Price per share of the Common Stock payable to holders of the Offering Shares tendering their Offering Shares pursuant to such tender offer shall be equal to the quotient obtained by dividing: (i) the aggregate amount on deposit in the Trust Account as of two business days prior to the consummation of the initial Business Combination, including interest not previously released to the Corporation to pay its taxes, by (ii) the total number of then outstanding Offering Shares. If the Corporation offers to redeem the Offering Shares in conjunction with a stockholder vote on the proposed initial Business Combination pursuant to a proxy solicitation, the Redemption Price per share of the Common Stock payable to holders of the Offering Shares exercising their Redemption Rights shall be equal to the quotient obtained by dividing (a) the aggregate amount on deposit in the Trust Account as of two business days prior to the consummation of the initial Business Combination, including interest not previously released to the Corporation to pay its taxes, by (b) the total number of then outstanding Offering Shares.

(c) If the Corporation offers to redeem the Offering Shares in conjunction with a stockholder vote on an initial Business Combination pursuant to a proxy solicitation, a Public Stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13(d)(3) of the Exchange Act), shall be restricted from seeking Redemption Rights with respect to more than an aggregate of 15% of the Offering Shares without the prior consent of the Corporation.

(d) In the event that the Corporation has not consummated an initial Business Combination within 24 months from the closing of the Offering, the Corporation shall (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than 10 business days thereafter subject to lawfully available funds therefor, redeem 100% of the Offering Shares in consideration of a per-share price, payable in cash, equal to the quotient obtained by dividing (A) the aggregate amount then on deposit in the Trust Account, including interest not previously released to the Corporation to pay its taxes (less up to $100,000 of such net interest to pay dissolution expenses), by (B) the total number of then outstanding Offering Shares, which redemption will completely extinguish rights of the Public Stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Board in accordance with applicable law, dissolve and liquidate, subject in each case to the Corporation’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law.

(e) If the Corporation offers to redeem the Offering Shares in conjunction with a stockholder vote on an initial Business Combination, the Corporation shall consummate the proposed initial Business Combination only if (i) such initial Business Combination is approved by the affirmative vote of the holders of a majority of the shares of the Common Stock that are voted at a stockholder meeting held to consider such initial Business Combination and (ii) the Redemption Limitation is not exceeded.

(f) If the Corporation conducts a tender offer pursuant to Section 9.2(b), the Corporation shall consummate the proposed initial Business Combination only if the Redemption Limitation is not exceeded.

Section 9.3 Distributions from the Trust Account.

(a) A Public Stockholder shall be entitled to receive funds from the Trust Account only as provided in Sections 9.2(a), 9.2(b), 9.2(d) or 9.7 hereof. In no other circumstances shall a Public Stockholder have any right or interest of any kind in or to distributions from the Trust Account, and no stockholder other than a Public Stockholder shall have any interest in or to the Trust Account.

(b) Each Public Stockholder that does not exercise its Redemption Rights shall retain its interest in the Corporation and shall be deemed to have given its consent to the release of the remaining funds in the Trust Account to the Corporation, and following payment to any Public Stockholders exercising their Redemption Rights, the remaining funds in the Trust Account shall be released to the Corporation.

7

(c) The exercise by a Public Stockholder of the Redemption Rights shall be conditioned on such Public Stockholder following the specific procedures for redemptions set forth by the Corporation in any applicable tender offer or proxy materials sent to the Public Stockholders relating to the proposed initial Business Combination. Payment of the amounts necessary to satisfy the Redemption Rights properly exercised shall be made as promptly as practical after the consummation of the initial Business Combination.

Section 9.4 Share Issuances. Prior to the consummation of the Corporation’s initial Business Combination, the Corporation shall not issue any additional shares of capital stock of the Corporation that would entitle the holders thereof to receive funds from the Trust Account or vote on any initial Business Combination, on any pre-Business Combination activity or on any amendment to this Article IX.

Section 9.5 Transactions with Affiliates. In the event the Corporation enters into an initial Business Combination with a target business that is affiliated with any of the Founders, any director or officer of the Corporation or any of their respective affiliates, the Corporation, or a committee of the independent directors of the Corporation, shall obtain an opinion from an independent accounting firm or an independent investment banking firm that is a member of the Financial Industry Regulatory Authority that such Business Combination is fair to the Corporation from a financial point of view.

Section 9.6 No Transactions with Other Blank Check Companies. The Corporation shall not enter into an initial Business Combination with another blank check company or a similar company with nominal operations.

Section 9.7 Additional Redemption Rights. If, in accordance with Section 9.1(a), any amendment is made to this Article IX, the Public Stockholders shall be provided with the opportunity to redeem their Offering Shares upon the approval of any such amendment, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest not previously released to the Corporation to pay its taxes, divided by the number of then outstanding Offering Shares; provided, however, that any such amendment will be voided, and this Article IX will remain unchanged, if any stockholders who wish to redeem are unable to redeem due to the Redemption Limitation.

ARTICLE X

CORPORATE OPPORTUNITY

To the extent allowed by law, the doctrine of corporate opportunity, or any other analogous doctrine, shall not apply with respect to the Corporation or any of its officers or directors, and the Corporation renounces any expectancy that any of the directors or officers of the Corporation will offer any such corporate opportunity of which he or she may become aware to the Corporation, except, the doctrine of corporate opportunity shall apply with respect to any of the directors or officers of the Corporation only with respect to a corporate opportunity that was offered to such person solely in his or her capacity as a director or officer of the Corporation and such opportunity is one the Corporation is legally and contractually permitted to undertake and would otherwise be reasonable for the Corporation to pursue, and to the extent the director or officer is permitted to refer that opportunity to the Corporation without violating any legal obligation.
