Any attempted Transfer of Voting Shares or any interest therein in violation of this Section 5 shall be null and void. This Section 5 shall not prohibit a Transfer of Voting Shares by any Voting Party (or prohibit any Voting Party from entering into any contract, option or other agreement with respect to, or prohibit such Voting Party from consenting to, a Transfer of any of his, her or its Voting Shares or such Voting Party’s voting or economic interest therein) (i) to any Affiliates or any member of such Voting Party’s immediate family or any Affiliates of such Voting Party, (ii) by gift to (a) in the case of an individual, a member of such Voting Party’s immediate family, (b) a trust, the beneficiary of which is, or is an Affiliate of, such Voting Party or, in the case of an individual, a member of such Voting Party’s immediate family, or (c) a charitable organization, (iii) in the case of an individual, by virtue of laws of descent and distribution upon death, (iv) in the case of an individual, pursuant to a qualified domestic relations order or in connection with a divorce settlement, (v) in the case of a trust, by distribution to one or more of the permissible beneficiaries of such trust, (vi) in the event of SPAC’s liquidation prior to SPAC’s completion of the Business Combination or (vii) in the case of an entity, by virtue of the laws of such Voting Party’s jurisdiction of incorporation or organization, such Voting Party’s organizational documents or the rights attaching to the equity interests in such Voting Party upon dissolution of such Voting Party; provided, however, that in the case of clauses (i) through (v), as a pre-condition to such Transfer, the transferee must agree in a writing, reasonably satisfactory in form and substance to SPAC and Pubco, to be bound by all of the terms of this Agreement.

8 Vesting Provisions.

(a) Sponsor agrees that, on the Closing Date, 25% of the Ordinary Shares to be received by Sponsor at the Closing in accordance with the terms of the Business Combination Agreement in exchange for the shares of Class B common stock, par value $0.0001 per share, of SPAC (the “Founder Shares”) (or the shares of SPAC Class A Common Stock into which the Founder Shares were converted in connection with the Transactions) (the “Earnout Shares”), shall be transferred to an escrow agent reasonably acceptable to Sponsor and Pubco (the “Escrow Agent”), and such Earnout Shares shall thereafter be held by the Escrow Agent in accordance with the terms of this Section 8, the Business Combination Agreement and an escrow agreement reasonably acceptable to Pubco and Sponsor.

(b) The Earnout Shares shall automatically vest in Sponsor, and Sponsor and Pubco shall cause the Earnout Shares to be released to Sponsor promptly, following the first date during the Earnout Period on which the Share Price Level equals or exceeds $12.50 (as equitably adjusted on account of any subdivision, capitalization, share dividend, combination, reclassification or similar equity restructuring transaction or any changes in the Ordinary Shares as a result of a merger, consolidation, reorganization, recapitalization, business combination or similar transaction involving Pubco) (the “Price Target”). Subject to Section 8(c), in the event that the Price Target is not met during the Earnout Period, then this Section 8 shall terminate and no Earnout Shares shall vest in Sponsor hereunder and such shares shall be forfeited, released and returned to Pubco upon the expiration of the Earnout Period.

(c) If, during the Earnout Period, there is a Pubco Sale that will result in the holders of Ordinary Shares receiving a per share price (based on the value of the cash, securities or in-kind consideration being delivered in respect of Ordinary Shares, as determined in good faith by the Board of Directors of Pubco) (the “Per Share Price”) equal to or in excess of the Price Target, then immediately prior to the consummation of such Pubco Sale (a) if the Price Target has not previously been met, it shall be deemed to have been met and (b) Sponsor and Pubco shall cause the Earnout Shares to be released to Sponsor and Sponsor shall be eligible to participate in such Pubco Sale. If, during the Earnout Period, there is a Pubco Sale that will result in the holders of Ordinary Shares receiving a Per Share Price that is less than the Price Target, then this Section 8 shall terminate and no Earnout Shares shall vest in Sponsor hereunder in connection with or following completion of the Pubco Sale and such shares shall be forfeited upon the completion of the Pubco Sale.

(d) As used in this Section 8, (i) the term “Earnout Period” means the period beginning on the date that is sixty (60) days after the Closing Date and ending on the date that is the fifth anniversary of the Closing Date; (ii) the term “Share Price Level” means the Pubco VWAP for any twenty (20) trading days (which may or may not be consecutive) within any consecutive thirty (30) trading day period.

9 Sponsor Lock-up.

(a) Sponsor agrees that it shall not effectuate a Transfer of the Restricted Securities that are held by Sponsor during the period commencing on the Closing Date and ending on (i) for 50% of the Restricted Securities held by Sponsor, the earlier of (1) one (1) year after the Closing Date and (2) the date on which the Pubco VWAP is equal to or greater than $12.50 (as equitably adjusted on account of any subdivision, share split or consolidation, capitalization, share dividend, reorganization, combination, reclassification or similar equity restructuring transaction or any changes in the Ordinary Shares as a result of a merger, consolidation, reorganization, recapitalization, business combination or similar transaction involving Pubco) for a period of at least twenty (20) trading days (which may or may not be consecutive) within any consecutive thirty (30) trading day period commencing after the Closing Date and (ii) for all other Restricted Securities held by Sponsor, one (1) year after the Closing Date (the “Sponsor Lock-Up Period” and such restrictions on Transfer during the Sponsor Lock-Up Period, the “Sponsor Lock-Up”).

(iv) the exercise of any options, warrants or other convertible securities to purchase Ordinary Shares (which exercises may be effected on a cashless basis to the extent the instruments representing such options or warrants permit exercises on a cashless basis); provided, that any Ordinary Shares issued upon such exercise shall be subject to the Sponsor Lock-Up Period;

(v) in the event of the Company’s liquidation, merger, share exchange, reorganization or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property (including, for the avoidance of doubt, a Pubco Sale);

(vi) in connection with any bona fide mortgage, pledge, hypothecation, encumbrance or other grant of a security interest to an unaffiliated financial institution in connection with any bona fide loan or debt transaction or enforcement thereunder, including foreclosure thereof (so long as any such mortgage, pledge, hypothecation, encumbrance or grant of security interest shall be on terms consistent with customary loan or debt transactions), and Sponsor shall provide the Company with written notice prior to entering into such transaction; and

(vii) for purposes of satisfying any withholding and/or other taxes that become payable in connection with the exchange of SPAC Private Warrants held by Sponsor for Pubco Private Warrants in connection with the consummation of the Business Combination;

provided, that in the case of clauses (i) through (iii), such transferee, to the extent not already party hereto, must enter into a written agreement agreeing to be bound by the restrictions herein.

(c) If any Transfer is made or attempted contrary to the provisions of this Agreement, such Transfer shall be null and void ab initio, and the Company shall refuse to recognize any such transferee of the Restricted Securities as one of its equity holders for any purpose.

A COPY OF SUCH SPONSOR SUPPORT AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

5

(e) For the avoidance of any doubt, Sponsor shall retain all of the rights of a holder of the Restricted Securities held by Sponsor during the Sponsor Lock-Up Period, including, where applicable, the right to vote any Restricted Securities, in each case, for so long as Sponsor owns such Restricted Securities.

(f) As used in this Section ‎9, (i) “Transfer” shall mean the (1) sale of, offer to sell, contract or agreement to sell, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Exchange Act and the rules and regulations of the U.S. Securities and Exchange Commission promulgated thereunder with respect to, any security, (2) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (3) public announcement of any intention to effect any transaction specified in clause (1) or (2), and (ii) “Restricted Securities” shall mean the Ordinary Shares and Pubco Private Warrants to be received by Sponsor pursuant to the Business Combination Agreement, together with any (1) securities paid as dividends or distributions with respect to such securities, (2) securities into which such securities are exchanged or converted and (3) securities issued or issuable upon the exercise of the Pubco Private Warrants.

10 Redemption Rights. Each Voting Party agrees not to exercise any right to redeem any Voting Shares Beneficially Owned as of the date hereof or acquired and held in such capacity subsequent to the date hereof.

11 Termination. This Agreement shall automatically terminate upon the earliest to occur of (i) the SPAC Merger Effective Time and (ii) the date on which the Business Combination Agreement is validly terminated in accordance with its terms; provided that (x) in the case of clause (i) those rights and obligations that are explicitly provided for to survive after the Closing (including Section 8, Section 9 and any related definitions used therein) shall continue to apply in accordance with their terms and (y) this Section 11 and Sections 13, 14, 15, 16, 17, 18, 20 and 21 hereof shall continue to apply. In the event of a valid termination of the Business Combination Agreement in accordance with its terms, this Agreement shall be of no force and effect and the parties agree that the Prior Letter Agreement (as defined herein) shall be reinstated and shall be effective and binding upon them in accordance with its terms notwithstanding the termination of such agreement herein. No such termination or reinstatement of the Prior Letter Agreement shall relieve any Voting Party, SPAC or Pubco from any liability resulting from a willful breach of this Agreement occurring prior to such termination or reinstatement.

12 No Agreement as Director or Officer. Each Voting Party is signing this Agreement solely in its capacity as a stockholder of SPAC. No Voting Party makes any agreement or understanding in this Agreement in such Voting Party’s capacity (or in the capacity of any Affiliate, partner or employee of Voting Party) as a director or officer of SPAC or any of its Subsidiaries (if Voting Party holds such office). Nothing in this Agreement will limit or affect any actions or omissions taken by a Voting Party (or any Affiliate, partner or employee of Voting Party) in his, her or its capacity as a director or officer of SPAC, and no actions or omissions taken in any Voting Party’s capacity (or in the capacity of any Affiliate, partner or employee of Voting Party) as a director or officer shall be deemed a breach of this Agreement. Nothing in this Agreement will be construed to prohibit, limit or restrict a Voting Party (or any Affiliate, partner or employee of Voting Party) from exercising his or her fiduciary duties as an officer or director to SPAC or its Subsidiaries.

13 Specific Enforcement. It is agreed and understood that monetary damages would not adequately compensate an injured party for the breach of this Agreement by any party hereto and, accordingly, that this Agreement shall be specifically enforceable, in addition to any other remedy to which such injured party is entitled at law or in equity, and that any breach of this Agreement shall be the proper subject of a temporary or permanent injunction or restraining order. Further, each party hereto waives any claim or defense that there is an adequate remedy at law for such breach or threatened breach or an award of specific performance is not an appropriate remedy for any reason at law or equity and agrees that a party’s rights would be materially and adversely affected if the obligations of the other parties under this Agreement were not carried out in accordance with the terms and conditions hereof.

14 Entire Agreement. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement, or, in the case of a waiver, by the party against whom the waiver is to be effective. No waiver of any provisions hereof by either party shall be deemed a waiver of any other provisions hereof by such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party. Without limiting the generality of the foregoing, SPAC and each of the Voting Parties hereby agree that as of the date of this Agreement, the letter agreement, dated as of February 11, 2021, by and among SPAC and the Voting Parties (the “Prior Letter Agreement”) shall have no further force or effect unless and until this Agreement is terminated pursuant to Section 11(ii).
