expressly forth in the Letter Agreement, the Merger Agreement or other Transaction Documents, (iii) take any action that would reasonably

any Transaction Document and the Letter Agreement) (such agreements, collectively, the “Sponsor Affiliate Agreements”)
will be terminated effective as of the First Effective Time (other than those Sponsor Affiliate Agreements with obligations that will

the discharge of such obligations upon the Closing), and thereupon shall be of no further force or effect, without any further action
on the part of any of the Sponsor or SPAC, and on and from the effectiveness of such terminations neither SPAC, the Sponsor, nor any of
their respective affiliates or subsidiaries shall have any further rights, duties, liabilities or obligations under any of the Sponsor

with any fractional shares rounded down to the nearest full share; provided that the number of SPAC B Ordinary Shares so surrendered
shall not under any event exceed thirty percent (30%) of the aggregate number of SPAC Class B Ordinary Shares held by Sponsor as
of the date hereof.


 


Section 4.13           Lock-Up
Provisions.


 


(a)            Subject
to the exceptions set forth herein, during the applicable Lock-Up Period (as defined below), Sponsor agrees not to, without the prior
written consent of the Company Board, Transfer any Locked-Up Securities held by it. The foregoing limitations shall remain in full force
and effect for a period of six (6) months from and after the Closing (such period, the “Lock-Up Period”) with
respect to all the Locked-Up Securities. For purpose of this Section 4.13, “Locked-Up Securities” means any Company
Ordinary Shares or Company Warrants that are held by Sponsor immediately after the First Effective Time and any Company Ordinary Shares
acquired by Sponsor upon the conversion, exercise or exchange of the SPAC Warrants or Company Warrants.


 


(b)            The
restrictions set forth in Section 4.13(a) (the “Lock-Up Restrictions”) shall not apply to:


 


(i)            transfers
by the Sponsor to (A) any shareholder, partner or member of the Sponsor via dividend or share repurchase as part of a distribution,
or (B) any Person that is an affiliate of the Sponsor;


 


(ii)            transfers
by virtue of the Laws of the state of Sponsor’s organization and Sponsor’s Organizational Documents upon dissolution of Sponsor;


 






    10


     


    

 


(iii)            pledges
of any Locked-Up Securities to a financial institution that create a mere security interest in such Locked-Up Securities pursuant to a
bona fide loan or indebtedness transaction so long as Sponsor continues to control the exercise of the voting rights of such pledged Locked-Up
Securities (as well as any foreclosures on such pledged Locked-Up Securities so long as the transferee in such foreclosure agrees to become
a party to this Agreement and be bound by all obligations applicable to Sponsor, provided that such agreement shall only take effect
in the event that the transferee takes possession of the Locked-Up Securities as a result of foreclosure);


 


(iv)           transfers
of any Company Ordinary Shares acquired as part of the Permitted Financing or Subsequent Equity Financing;


 


(v)            transactions
relating to Company Ordinary Shares or other securities convertible into or exercisable or exchangeable for Company Ordinary Shares acquired
in open market transactions after the Closing, provided that no such transaction is required to be, or is, publicly announced (whether
on Form 4, Form 5 or otherwise, other than a required filing on Schedule 13F, 13G or 13G/A) during the applicable Lock-Up Period;


 


(vi)            the
exercise of any options or warrants to purchase Company 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);


 


(vii)           the
establishment, at any time after the Closing, by the Company of a trading plan providing for the sale of Company Ordinary Shares that
meets the requirements of Rule 10b5-1(c) under the Exchange Act (a “Trading Plan”); provided, however,
that no sales of Locked-Up Securities, shall be made by Sponsor pursuant to such Trading Plan during the applicable Lock-Up Period and
no public announcement or filing is voluntarily made regarding such plan during the applicable Lock-Up Period;


 


(viii)          transfers
made in connection with a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s
shareholders having the right to exchange their Company Ordinary Shares for cash, securities or other property subsequent to the Closing
Date; and


 


(ix)            transactions
to satisfy any U.S. federal, state, or local income tax obligations of Sponsor (or its direct or indirect owners) arising from a change
in the U.S. Internal Revenue Code of 1986, as amended (the “Code”), a change in or promulgation of new U.S. Treasury
Regulations, or promulgation of any judicial or administrative guidance, in each case, after the date on which the Merger Agreement was
executed by the parties, and such change or promulgation prevents the Mergers from qualifying as a “reorganization” pursuant
to Section 368 of the Code, in each case, solely to the extent necessary to cover the increase in the U.S. income tax liability of
Sponsor directly resulting from such revised tax treatment of the Mergers;


 


provided,
however, that in the case of clauses (i) through (iii), these permitted transferees must enter into a written agreement,
in substantially the form of this Agreement, agreeing to be bound by the Lock-Up Restrictions and shall have the same rights and benefits
under this Agreement. For purposes of this paragraph, “affiliate” shall have the meaning set forth in Rule 405 under
the Securities Act of 1933, as amended.


 






    11


     


    

 


(c)            For
the avoidance of doubt, Sponsor shall retain all of its rights as a shareholder of the Company during the Lock-Up Period, including the
right to vote any Locked-Up Securities or receive any dividends or distributions thereon.


 


(d)            In
furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the Locked-Up Securities,
are hereby authorized to decline to make any transfer of securities if such Transfer would constitute a violation or breach of the Lock-Up
