Third. The purpose of the corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware.

Fourth. The total number of shares of all classes of capital stock, each with a par value of $0.0001 per share, which the Corporation is authorized to issue is 551,000,000, consisting of (a) 550,000,000 shares of common stock (the “Common Stock”), including two separate series of Common Stock consisting of (i) 500,000,000 shares of Class A Common Stock (the “Class A Common Stock”) and (ii) 50,000,000 shares of Class B Common Stock (the “Class B Common Stock”), and (b) 1,000,000 shares of preferred stock (the “Preferred Stock”).

Fifth. The Preferred Stock may be issued in one or more series from time to time, with each such series to consist of such number of shares and to have such voting powers, full or limited, or no voting powers, and such designations, preferences and relative, participating, optional or other special rights, and the qualifications, limitations or restrictions thereof, as shall be stated in the resolution or resolutions providing for the issuance of such series adopted by the board of directors of the Corporation (the “Board”) 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 now or hereafter provided by law, to adopt any such resolution or resolutions.

Sixth. The number of authorized shares of the Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority in voting power of the stock of the Corporation entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto), and no vote of the holders of any of the Preferred Stock voting separately as a class shall be required therefor, unless a vote of any such holder is required pursuant to this Amended and Restated Certificate (including any certificate of designation relating to any series of Preferred Stock).

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

(b) 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 on which the holders of the Common Stock are entitled to vote.

(c) 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, holders of the Class A Common Stock and holders of the Class B Common Stock, voting together as a single class, 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. Notwithstanding the foregoing, except as otherwise required by law or this Amended and Restated Certificate (including a Preferred Stock Designation), holders of shares of any series 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 or other series of Common Stock if the holders of such affected series of Preferred Stock or Common Stock, as applicable, 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).

(d) The number of authorized shares of the Class A Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority in voting power of the stock of the Corporation entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto), and no vote of the holders of any of the Class A Common Stock voting separately as a class shall be required therefor, unless a vote of any such holder is required pursuant to this Amended and Restated Certificate.

Eighth. Class B Common Stock. (a) Shares of Class B Common Stock shall be convertible into shares of Class A Common Stock on a one-for-one basis (the “Initial Conversion Ratio”) (i) at any time and from time to time at the option of the holder thereof and (ii) automatically upon the completion of the Business Combination (as defined below).

(b) Notwithstanding the Initial Conversion Ratio, in the case that additional shares of Class A Common Stock or Equity-linked Securities (as defined below) are issued or deemed issued in excess of the amounts sold in the Corporation’s initial public offering of securities (the “Offering”) and related to the closing of the Business Combination (as defined below), all issued and outstanding shares of Class B Common Stock shall automatically convert into shares of Class A Common Stock at the time of the closing of the Corporation’s initial merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (“Business Combination”) at a ratio for which the shares of Class B Common Stock shall convert into shares of Class A Common Stock will be adjusted such that the number of shares of Class A Common Stock issuable upon conversion of all shares of Class B Common Stock will equal, in the aggregate, 25% of the sum of (i) the total number of shares of Class A Common Stock issued and outstanding upon completion of the Offering plus (ii) the sum of all shares of Class A Common Stock issued or deemed issued or issuable upon conversion or exercise of any Equity-linked Securities issued or deemed issued in connection with a Business Combination (including shares issued or issuable pursuant to any forward purchase agreement entered into with the Corporation at the time of the completion of the Offering but not any warrants issued pursuant to such agreement), excluding (1) any shares of Class A Common Stock or Equity-linked Securities issued, or to be issued, to any seller in a Business Combination, and (2) any private placement warrants issued to the Sponsor (as defined below) or any of their affiliates upon conversion of working capital loans.

As used herein, the term “Equity-linked Securities” means any securities of the Corporation which are convertible, exercisable or exchangeable for shares of Class A common stock issued in connection with a Business Combination.

(c) Notwithstanding anything to the contrary contained herein, (i) the foregoing adjustment to the Initial Conversion Ratio may be waived as to any particular issuance or deemed issuance of additional shares of Class A Common Stock or Equity-linked Securities by the written consent or agreement of holders of a majority of the shares of Class B Common Stock then outstanding consenting or agreeing separately as a single class in the manner provided in Section 8(f), and (ii) in no event shall the Class B Common Stock convert into Class A Common Stock at a ratio that is less than one-for-one.

(d) The foregoing conversion ratio shall also be adjusted to account for any subdivision (by stock split, subdivision, exchange, stock dividend, reclassification, recapitalization or otherwise) or combination (by reverse stock split, exchange, reclassification, recapitalization or otherwise) or similar reclassification or recapitalization of the outstanding shares of Class A Common Stock into a greater or lesser number of shares occurring after the original filing of this Amended and Restated Certificate without a proportionate and corresponding subdivision, combination or similar reclassification or recapitalization of the outstanding shares of Class B Common Stock.

(e) Each share of Class B Common Stock shall convert into its pro rata number of shares of Class A Common Stock pursuant to this Section 8. The pro rata share for each holder of Class B Common Stock will be determined as follows: Each share of Class B Common Stock shall convert into such number of shares of Class A Common Stock as is equal to the product of 1 multiplied by a fraction, the numerator of which shall be the total number of shares of Class A Common Stock into which all of the issued and outstanding shares of Class B Common Stock shall be converted pursuant to this Section 8 and the denominator of which shall be the total number of issued and outstanding shares of Class B Common Stock at the time of conversion.

(f)   Voting. For so long as any shares of Class B Common Stock shall remain outstanding, the Corporation shall not, without the prior vote or written consent of the holders of a majority of the shares of Class B Common Stock then outstanding, voting separately as a single class, amend, alter or repeal any provision of this Amended and Restated Certificate, whether by merger, consolidation or otherwise, if such amendment, alteration or repeal would alter or change the powers, preferences or relative, participating, optional or other or special rights of the Class B Common Stock. Any action required or permitted to be taken at any meeting of the holders of Class B Common Stock 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, shall be signed by the holders of the outstanding Class B Common 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 Class B Common Stock were present and voted 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 minutes of proceedings of stockholders are recorded. Delivery made to the Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested. Prompt written notice of the taking of corporate action without a meeting by less than unanimous written consent of the holders of Class B Common Stock shall, to the extent required by law, be given to those holders of Class B Common Stock who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for notice of such meeting had been the date that written consents signed by a sufficient number of holders of Class B Common Stock to take the action were delivered to the Corporation. The holders of Class B Common Stock are entitled to vote as a separate class to increase the authorized number of shares of Class B Common Stock.

Ninth. Subject to the rights of the holders of Preferred Stock, the holders of shares of Common Stock shall be entitled to receive such dividends and other distributions (payable in cash, property or capital stock of the Corporation) when, as and if declared thereon by the Board from time to time out of any assets or funds of the Corporation legally available therefor and shall share equally on a per share basis in such dividends and distributions subject to such rights of the holders of Preferred Stock.

Tenth. 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, and subject to the rights of the holders of Preferred Stock in respect thereof, the holders of 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, treating the Class B Common Stock on an as-converted basis.

Eleventh. 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.

Twelfth. The incorporator of the corporation is Sherie Hollinger, c/o Kirkland & Ellis LLP, whose mailing address is 609 Main Street, Houston, Texas 77002.

Thirteenth. Number, Election and Term of the Board. (a) The number of directors of the Corporation shall be fixed from time to time in the manner provided in the Amended and Restated Bylaws of the Corporation (“Bylaws”).

(b) Subject to Paragraph SIXTEENTH hereof, commencing at the first annual meeting of the stockholders, and at each annual meeting of the stockholders thereafter, directors elected to succeed those directors whose terms expire shall be elected for a term of office to expire at the third annual meeting of the stockholders after their election.

(c) Subject to Paragraph SIXTEENTH hereof, a director shall hold office until the annual meeting for the year in which his or her term expires and until his or her successor has been elected and qualified, subject, however, to such director’s earlier death, resignation, retirement, disqualification or removal.

(d) Unless, and except to the extent that, the Bylaws shall so require, the election of directors of the corporation need not be by written ballot.

Fourteenth. Subject to Paragraph SIXTEENTH hereof, newly created directorships resulting from an increase in the number of directors and any vacancies on the Board resulting from death, resignation, retirement, disqualification, removal or other cause may be filled solely and exclusively by a majority vote of the remaining directors then in office, even if less than a quorum, or by a sole remaining director (and not by stockholders), and any director so chosen shall hold office for the remainder of the full term of the director to which the new directorship was added or in which the vacancy occurred and until his or her successor has been elected and qualified, subject, however, to such director’s earlier death, resignation, retirement, disqualification or removal.

Fifteenth. Subject to Paragraph SIXTEENTH hereof and except as otherwise required by this Amended and Restated Certificate (including as set forth on Paragraph THIRTY-SECOND hereof), any or all of the directors may be removed from office at any time, but only for cause and only by the affirmative vote of holders of a majority of the voting power of all then outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class.

Sixteenth. Notwithstanding any other provision of Paragraphs THIRTEENTH, FOURTEENTH and FIFTEENTH, and except as otherwise required by law, whenever the holders of one or more series of the Preferred Stock shall have the right, voting separately by class or series, to elect one or more directors, the term of office, the filling of vacancies, the removal from office and other features of such directorships shall be governed by the terms of such series of the Preferred Stock as set forth in this Amended and Restated Certificate (including any Preferred Stock Designation) and such directors shall not be included in any of the classes created pursuant to Paragraphs THIRTEENTH, FOURTEENTH and FIFTEENTH, unless expressly provided by such terms.

Seventeenth. In furtherance and not in limitation of the powers conferred by law, subject to any limitations contained in this Amended and Restated Certificate, the Board is expressly authorized to make, alter and repeal the bylaws of the corporation, but any bylaws adopted by the Board of Directors may be adopted, amended, altered or repealed by the stockholders entitled to vote thereon; provided, however, that in addition to any vote of the holders of any class or series of capital stock of the Corporation required by law or by this Amended and Restated Certificate (including any Preferred Stock Designation), the affirmative vote of the holders of at least a majority of the voting power of all then outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required for the stockholders to adopt, amend, alter or repeal the bylaws; and provided further, however, that no bylaws hereafter adopted by the stockholders shall invalidate any prior act of the Board that would have been valid if such bylaws had not been adopted.

Eighteenth. To the maximum extent permitted under the General Corporation Law of the State of Delaware, the Corporation renounces any interest or expectancy of the Corporation in, or in being offered an opportunity to participate in, business opportunities that are from time to time presented to its directors who are not employees of the Corporation or any of its subsidiaries (“Outside Directors”), other than any such opportunity expressly presented to an Outside Director in such Outside Director’s capacity as a director of the Corporation; and no such Outside Director shall be liable to the Corporation or its stockholders for breach of any fiduciary or other duty by reason of the fact that such Outside Director personally or on behalf of any other person pursues or acquires such business opportunity, directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to the Corporation or its subsidiaries. For purposes of this paragraph EIGHTEENTH, a director shall not be deemed to be an employee of the Corporation solely by reason of holding such position. No amendment or repeal of this paragraph EIGHTEENTH shall apply to or have any effect on the liability or alleged liability of any Outside Director for or with respect to business opportunities of which such Outside Director becomes aware prior to such amendment or repeal. Any person purchasing or otherwise acquiring any interest in any capital stock of the Corporation shall be deemed to have notice of, and to have consented to the provisions of this paragraph.

Nineteenth. Subject to the rights, if any, of the holders of any outstanding series of the Preferred Stock, and to the requirements of applicable law, special meetings of stockholders of the Corporation may be called only by the Chairman of the Board, Chief Executive Officer of the Corporation, or the Board pursuant to a resolution adopted by a majority of the Board, and the ability of the stockholders to call a special meeting is hereby specifically denied. Except as provided in the foregoing sentence, special meetings of stockholders may not be called by another person or persons.

Twentieth. 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.

Twenty-first. Except as may be otherwise provided for or fixed pursuant to this Amended and Restated Certificate (including any Preferred Stock Designation) relating to the rights of the holders of any outstanding series of Preferred Stock, subsequent to the consummation of the Offering, any action required or permitted to be taken by the stockholders of the Corporation must be effected by a duly called annual or special meeting of such stockholders and may not be effected by written consent of the stockholders.

Twenty-second. 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 for any liability (i) for any breach of the director’s duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. Any repeal or modification of this paragraph shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification.

Twenty-third. 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 paragraph TWENTY-THIRD or otherwise. The rights to indemnification and advancement of expenses conferred by this paragraph TWENTY-THIRD 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 paragraph TWENTY-THIRD, 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 paragraph TWENTY-THIRD 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 paragraph TWENTY-THIRD 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 paragraph TWENTY-THIRD, 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 paragraph TWENTY-THIRD 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.

Twenty-fourth. Business Combination Requirements. (a) The provisions of this paragraph TWENTY-FOURTH and the paragraphs TWENTY-FIFTH, TWENTY-SIXTH, TWENTY-SEVENTH, TWENTY-EIGHTH, TWENTY-NINTH, THIRTIETH, THIRTY-FIRST and THIRTY-SECOND 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 paragraph TWENTY-FOUR and the paragraphs TWENTY-FIFTH, TWENTY-SIXTH, TWENTY-SEVENTH, TWENTY-EIGHTH, TWENTY-NINTH, THIRTIETH, THIRTY-FIRST and THIRTY-SECOND 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 (the “SEC”) on , 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 withdrawal of interest to pay the Corporation’s 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 shares in connection with a vote seeking to amend any provisions of this Amended and Restated Certificate as described in paragraph THIRTIETH, or (iii) 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, subject to applicable law. Holders of shares of the 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 holder is XPDI Sponsor LLC (the “Sponsor”) or officers or directors of the Corporation, or affiliates of any of the foregoing) are referred to herein as “Public Stockholders.”

Twenty-fifth. 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, out of funds legally available therefor, upon the consummation of the initial Business Combination pursuant to, and subject to the limitations of, this paragraph TWENTY-FIFTH, Sections (b) and (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 this paragraph TWENTY-FIFTH, Section (b) hereof (the “Redemption Price”); provided, however, that the Corporation shall not redeem or repurchase 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) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (or any successor rule)) in excess of $5 million or any greater net tangible asset or cash requirement which may be contained in the agreement relating to 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 warrant 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 under the Exchange Act (or any successor rules or regulations) and filing proxy materials with 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 this paragraph TWENTY-FIFTH, Section (a) hereof pursuant to a tender offer in accordance with Rule 13e-4 and Regulation 14E under 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 under 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 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 this paragraph TWENTY- FIFTH, Section (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 paragraph TWENTY-FIFTH, Section (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 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 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.

(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 ten 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 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 vote of a majority of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon, unless the matter is one upon which, by applicable law, a different vote is required, in which case such provision shall govern and control the decision with respect to such matter (or approved by such other vote as the applicable stock exchange rules then in effect may require) and (ii) the Redemption Limitation is not exceeded.

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

Twenty-sixth. Distributions from the Trust Account. (a) A Public Stockholder shall be entitled to receive funds from the Trust Account only as provided in paragraph TWENTY-FIFTH, Sections (a), (b) and (d) or paragraph TWENTY-NINTH 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.

(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.

Twenty-seventh. 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.

Twenty-eighth. In the event the Corporation enters into an initial Business Combination with a target business that is affiliated with the Sponsor, or the directors or officers of the Corporation, 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.

Twenty-ninth. The Corporation shall not enter into an initial Business Combination solely with another blank check company or a similar company with nominal operations.

Thirtieth. If, in accordance with paragraph TWENTY-FOURTH, Section (a), any amendment is made to this Amended and Restated Certificate of Incorporation (a) to modify the substance or timing of the Corporation’s obligation to allow redemption in connection with its initial Business Combination or to redeem 100% of the Offering Shares if the Corporation has not consummated an initial Business Combination within 24 months from the date of the closing of the Offering or (b) with respect to any other provisions of this Amended and Restated Certificate of Incorporation relating to stockholders’ rights or pre-initial Business Combination activity, 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 taxes, divided by the number of then outstanding Offering Shares. The Corporation’s ability to provide such opportunity is subject to the Redemption Limitation.

Thirty-first. The Corporation’s initial Business Combination must occur with one or more target businesses that together have a fair market value of at least 80% of the assets held in the Trust Account (excluding any deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time the Corporation signs a definitive agreement in connection with the initial Business Combination.

Thirty-second. Notwithstanding any other provision in this Amended and Restated Certificate, prior to the closing of the initial Business Combination, the holders of Class B Common Stock shall have the exclusive right to elect and remove any director, and the holders of Class A Common Stock shall have no right to vote on the election or removal of any director. This paragraph THIRTY-SECOND may only be amended by a resolution passed by a majority the outstanding shares of Class B Common Stock entitled to vote thereon.

Thirty-third. 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, or any of their respective affiliates, in circumstances where the application of any such doctrine would conflict with any fiduciary duties or contractual obligations they may have as of the date of this Amended and Restated Certificate or in the future. In addition to the foregoing, the doctrine of corporate opportunity shall not apply to any other corporate opportunity with respect to any of the directors or officers of the Corporation unless such corporate opportunity is 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.

Thirty-fourth. Forum. (a) Unless the Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (the “Court of Chancery”) shall, to the fullest extent permitted by law, be the sole and exclusive forum for any stockholder (including a beneficial owner) to bring (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Corporation to the Corporation or the Corporation’s stockholders, (iii) any action asserting a claim against the Corporation, its directors, officers or employees arising pursuant to any provision of the DGCL or this Amended and Restated Certificate or the Bylaws, or (iv) any action asserting a claim against the Corporation, its directors, officers or employees governed by the internal affairs doctrine, except for, as to each of (i) through (iv) above, any claim as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or for which the Court of Chancery does not have subject matter jurisdiction. This exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations. Additionally, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended, against us or any of our directors, officers, other employees or agents.

(b) If any action the subject matter of which is within the scope of paragraph THIRTY-FOURTH, Section (a) immediately above 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 (i) 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 paragraph THIRTY-FOURTH, Section (a) immediately above (an “FSC Enforcement Action”) and (ii) having service of process made upon such stockholder in any such FSC Enforcement Action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder

(c) If any provision or provisions of this paragraph THIRTY-FOURTH, Section (c) shall be held to be invalid, illegal or unenforceable as applied to any person or entity or circumstance for any reason whatsoever, then, to the fullest extent permitted by law, the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this paragraph THIRTY FOURTH (including, without limitation, each portion of any sentence of this paragraph THIRTY-FOURTH containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) and the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this paragraph THIRTY-FOURTH.

Thirty-fifth. The Corporation reserves the right at any time and from time to time to amend, alter, change or repeal any provision contained in this Amended and Restated Certificate (including any Preferred Stock Designation), and other provisions authorized by the laws of the State of Delaware at the time in force that may be added or inserted, in the manner now or hereafter prescribed by this Amended and Restated Certificate and the DGCL; and, except as set forth in paragraphs TWENTY-SECOND and TWENTY-THIRD, all rights, preferences and privileges of whatever nature herein conferred upon stockholders, directors or any other persons by and pursuant to this Amended and Restated Certificate in its present form or as hereafter amended are granted subject to the right reserved in this paragraph THIRTY-FIFTH; provided, however, that paragraphs TWENTY-FOURTH, TWENTY-FIFTH, TWENTY-SIXTH, TWENTY-SEVENTH, TWENTY-EIGHTH, TWENTY-NINTH, THIRTIETH, THIRTY-FIRST and THIRTY-SECOND of this Amended and Restated Certificate may be amended only as provided therein.
