 NOW, THEREFORE,
in consideration of the premises and the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, each intending to be legally bound, hereby agree as
follows: 
 1. Agreement to Vote. The Sponsor, by this Agreement, with respect to its Parent Class B Shares,
hereby agrees to vote at any duly called meeting of the shareholders of Parent (or any adjournment or postponement thereof), and in any action by resolution of the shareholders of Parent, all of Sponsor’s Parent Class B Shares in favor of
the approval and adoption of the Business Combination Agreement and the transactions contemplated by the Business Combination Agreement. 

2. Lockup. 

(a) The Sponsor agrees that the Sponsor Shares and the Sponsor Warrants (collectively, the “Sponsor
Securities”) may not be transferred, assigned or sold (except to the extent set forth in Section 2(b)) (the “Lockup”) until the earliest to occur: (i) the termination of the Business
Combination Agreement in accordance with its terms and (ii) the Closing Date. 
 (b) Notwithstanding the provisions set
forth in Section 2(a), transfers, assignments and sales by the Sponsor of the Sponsor Securities are permitted (i) to Parent’s officers or directors, any affiliates












 
or family members of any of Parent’s officers or directors, any members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates;
(ii) in the case of an individual, by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, an affiliate of such person or to a
charitable organization; (iii) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order; (v) by
private sales or transfers made in connection with the consummation of the transactions contemplated by the Business Combination Agreement at prices no greater than the price at which the applicable Sponsor Securities were originally purchased;
(vi) by virtue of the Sponsor’s governing documents upon the winding up and subsequent liquidation or dissolution of the Sponsor; (vii) to Parent for no value for cancellation in connection with the consummation of the transactions
contemplated by the Business Combination Agreement; (viii) in the event of Parent’s liquidation prior to the completion of the transactions contemplated by the Business Combination Agreement; or (ix) in the event of completion of a
liquidation, merger, share exchange or other similar transaction which results in all of TopCo’s shareholders having the right to exchange their Parent Class A Shares for cash, securities or other property subsequent to the completion of
the transactions contemplated by the Business Combination Agreement; provided, however, that in the case of clauses (i) through (vi) these permitted transferees must enter into a written agreement agreeing to be bound by the restrictions
herein. For the avoidance of doubt, transfers of Sponsor Securities issued or issuable upon the exercise of the Sponsor Warrants or conversion of the Sponsor Securities shall be permitted regardless of whether a filing under Section 16(a) of
the Exchange Act shall be required or shall be voluntarily made with respect to such transfers; provided, that, for the avoidance of doubt, the obligations of the Sponsor hereunder shall be deemed to be satisfied by the existence of any stop
order and restrictions currently existing on the Sponsor Securities. 
 3. Waiver of Anti-dilution
Protection. The Sponsor hereby, subject to and conditioned upon the occurrence of the Closing, waives (for itself and for its successors and assigns) to the fullest extent of the law and the Amended and Restated Memorandum and
Articles of Association of Parent, and agrees not to assert or perfect, any rights to adjustment or other anti-dilution protections with respect to the rate that the Parent Class B Shares held by it convert into TopCo Ordinary Shares in
connection with the transactions contemplated by the Business Combination Agreement. 
 4. Deferral of Sponsor
Shares. Subject to and conditioned upon the occurrence of the Closing, immediately following the First Merger Effective Time, 1,250,000 Sponsor Shares held by Sponsor as of immediately prior to the First Merger Effective Time, which will have
been exchanged for TopCo Ordinary Shares (the “Deferred Sponsor Shares”) pursuant to the First Merger, shall become unvested and shall be subject to the following transfer restrictions and vesting and buyback provisions: 

(a) If, at any time during the five (5) years following the Closing (the “Vesting Period”), the TopCo
Ordinary Share Price is at or above a VWAP of $12.50 per share for any ten (10) trading days within any twenty (20) trading day period, one-half (1/2) of the Deferred Sponsor Shares shall immediately
vest and no longer be subject to the Buyback and the transfer restrictions provided for in Section 4(c) and Section 4(d), respectively. 

(b) If, at any time during the Vesting Period, the TopCo Ordinary Share Price is at or above a VWAP of $15.00 per share for
any ten (10) trading days within any twenty (20) trading day period, all remaining unvested Deferred Sponsor Shares shall immediately vest and no longer be subject to the Buyback and the transfer restrictions provided for in
Section 4(c) and Section 4(d), respectively. 
 (c) The Sponsor and
TopCo hereby agree that, the Deferred Sponsor Shares that do not vest in accordance with Section 4(a) and Section 4(b) during the Vesting Period are transferred back to TopCo for a consideration
equal to their nominal value, payable on such date, and shall be cancelled as 

  
 2 












 
soon as practicable by TopCo and without any encumbrance, third party right, further right, obligation or liability of any kind or nature on the part of Parent, TopCo or the Sponsor or any
otherparty (the “Buyback”). If, between the date of this Agreement and the Closing, the outstanding Sponsor Shares shall have been changed into a different number of shares or a different class, by reason of any dividend,
subdivision, reclassification, recapitalization, split, combination or exchange, or any similar event shall have occurred (including any of the foregoing in connection with the First Merger), then the number of Deferred Sponsor Shares to become
unvested and subject to the transfer restrictions and vesting and Buyback provisions set forth herein, will be equitably adjusted to reflect such change. The Sponsor and TopCo agree and undertake to enter into a confirmatory agreement in respect of
the transfer of the relevant Deferred Sponsor Shares at such time. 
 (d) Subject to the limitations contemplated herein,
the Sponsor shall be entitled to the voting and dividend rights generally granted to holders of TopCo Ordinary Shares with regard to the Deferred Sponsor Shares; provided that the Deferred Sponsor Shares shall not entitle the Sponsor, without
limiting Section 4(e), to any consideration in connection with any sale or other similar transaction and may not be offered, sold, transferred, redeemed, assigned, pledged, hypothecated, encumbered or otherwise disposed of
(whether by operation of law or otherwise) by the Sponsor or be subject to execution, attachment or similar process without the consent of TopCo, and shall bear a customary legend with respect to such transfer restrictions. Any attempt to so sell,
transfer, assign, pledge, hypothecate, encumber or otherwise dispose of such Deferred Sponsor Shares shall be null and void; provided, that, notwithstanding the foreging, transfers, assignments and sales by the Sponsor of the Deferred Sponsor Shares
are permitted (i) to Parent’s officers or directors, any affiliates or family members of any of Parent’s officers or directors, any members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any
employees of such affiliates; (ii) in the case of an individual, by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, an affiliate of
such person or to a charitable organization; (iii) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations
order; (v) by private sales or transfers made in connection with the consummation of the transactions contemplated by the Business Combination Agreement at prices no greater than the price at which the applicable Deferred Sponsor Shares were
originally purchased; (vi) by virtue of the Sponsor’s organizational documents upon the winding up and subsequent liquidation or dissolution of the Sponsor; (vii) to Parent for no value for cancellation in connection with the
consummation of the transactions contemplated by the Business Combination Agreement; (viii) in the event of Parent’s liquidation prior to the completion of the transactions contemplated by the Business Combination Agreement; or
(ix) in the event of completion of a liquidation, merger, share exchange or other similar transaction which results in all of TopCo’s shareholders having the right to exchange their Parent Class A Shares for cash, securities or other
property subsequent to the completion of the transactions contemplated by the Business Combination Agreement; provided, however, that in the case of clauses (i) through (vi) these permitted transferees must enter into a written agreement
agreeing to be bound by the restrictions herein. For the avoidance of doubt, transfers of the Deferred Sponsor Shares issuable in accordance with this Section 4 shall be permitted regardless of whether a filing under
Section 16(a) of the Exchange Act shall be required or shall be voluntarily made with respect to such transfers. 
 (e)
In the event that there is a Company Sale after the Closing and during the Vesting Period that will result in the holders of TopCo Ordinary Shares receiving a Company Sale Price equal to or in excess of the applicable price per share set forth set
forth in Section 4(a) and Section 4(b), then immediately prior to the consummation of the Company Sale any such vesting of Deferred Sponsor Shares set forth herein that has not previously occurred
shall be deemed to have occurred and the holders of such Deferred Sponsor Shares shall be eligible to participate in such Company Sale.

banking firm determines relevant and (ii) with respect to any other non-cash assets, the fair value thereof as of the date of valuation as determined by an independent, nationally recognized investment
