provided,
however, as to any particular Registrable Securities, such securities shall cease to be Registrable Securities when: (i) a
registration statement with respect to the sale of such securities shall have become effective under the Securities Act and such securities
shall have been sold, transferred, disposed of or exchanged in accordance with such Registration Statement; (ii) such securities
shall have been otherwise transferred, new certificates for such securities not bearing a legend restricting further transfer shall have
been delivered by the Company and subsequent public distribution of such securities shall not require registration under the Securities

Registration. The following shall be inserted as a new Section 3.5A of the YSB Shareholders Agreement:


 


“3.5A
Shelf Registration.


 





	 	(a)	Filing. The Company shall file within 20 days of the Second Merger Effective Time or within
    60 days of the Second Merger Effective Time if the Company is required to include therein additional financial information that is
    not included in the Form F-4 at the time of the Second Merger Effective Time, and use commercially reasonable efforts to cause
    to be declared effective as soon as practicable thereafter within 90 calendar days following the Second Merger Effective Time, but
    if the SEC notifies the Company that the Shelf will not be “reviewed” or will not be subject to further review, such
    effectiveness date shall be no later than the 10th business day after the date the Company is notified (orally or in writing, whichever
    is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject to further review,
    a Registration Statement for a Shelf Registration on Form F-1 or Form S-1, as applicable (the “Form F-1 Shelf”)
    or, if the Company is eligible to use a Registration Statement on Form F-3 or Form S-3, a Shelf Registration on Form F-3
    or Form S-3, as applicable (the “Form F-3 Shelf”, together with the Form F-1 Shelf, the “Shelf”),
    in each case, covering the resale of all the Registrable Securities (determined as of two business days prior to such filing) on
    a delayed or continuous basis; provided, however, that the Company’s obligations to include the Registrable Securities held
    by a holder of Registrable Securities (the “Holder”) in the Shelf are contingent upon such Holder furnishing in
    writing to the Company such information regarding the Holder, the securities of the Company held by the Holder and the intended method
    of disposition of the Registrable Securities as shall be reasonably requested by the Company to effect the registration of the Registrable
    Securities, and the Holder shall execute such documents in connection with such registration as the Company may reasonably request
    that are customary of a selling shareholder in similar situations. Such Shelf shall provide for the resale of the Registrable Securities
    included therein pursuant to any method or combination of methods legally available to, and requested by, any Holder named therein.
    The Company shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the SEC such amendments,
    including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use
    and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities in
    such Shelf. In the event the Company files a Form F-1 Shelf, the Company shall use its commercially reasonable efforts to convert
    the Form F-1 Shelf (and any Subsequent Shelf Registration) to a Form F-3 Shelf as soon as practicable after the Company
    is eligible to use Form F-3. References to Section 3.5 in Section 3.10 of the YSB Shareholders Agreement shall exclude
    this Section 3.5A.



 






    10


     


    

 





	 	(b)	Subsequent Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any
    reason at any time while Registrable Securities are still outstanding, the Company shall use its commercially reasonable efforts
    to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including obtaining
    the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts
    to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any order
    suspending the effectiveness of such Shelf or file an additional registration statement as a Shelf (a “Subsequent Shelf
    Registration”) registering the resale of all Registrable Securities (determined as of two business days prior to such filing),
    and pursuant to any method or combination of methods legally available to, and requested by, any Holder named therein. If a Subsequent
    Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration
    to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that
    the Subsequent Shelf Registration shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under
    the Securities Act) if the Company becomes a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities
    Act) at the most recent applicable eligibility determination date), and (ii) keep such Subsequent Shelf Registration continuously
    effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any
    Registrable Securities included in such Subsequent Shelf Registration. Any such Subsequent Shelf Registration shall be on Form F-3
    or Form S-3, as applicable, to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration
    shall be on another appropriate form.
	 	 	 
	 	(c)	Underwriting. If the Holders of Registrable Securities requesting registration under this
    Section 3.5A intend to distribute the Registrable Securities covered by their request by means of an underwriting, the provisions
    of Section 3.3(b) shall apply to such registration.”

to the Series A Holders, only by the Majority Series A Holders (and the relevant holders of the Ordinary Shares which the Series A

a majority of the outstanding Ordinary Shares; provided, however, that any Ordinary Holder may waive any of its own rights hereunder
without obtaining the consent of any other Ordinary Holders. Any amendment or waiver effected in accordance with this Section 10
shall be binding upon the Company, the Series A Holders, the Series B Holders, the Ordinary Holders and their respective permitted
transferees. Notwithstanding the foregoing and anything to the contrary contained herein, (i) only upon the prior written
consent of the Company and the Holders of at least a majority of the Registrable Securities at the time in question, compliance with
any of the provisions, covenants and conditions set forth in Section 3 (Registration Rights) of this Agreement may be waived, or
any of such provisions, covenants or conditions may be amended or modified; provided, however, that any amendment or modification to
Section 3 (Registration Rights) of this Agreement that would have a disproportionately adverse effect on any party’s rights
hereunder in any material respect shall require the prior written consent of such party, and (ii) no amendment or modification shall

value $0.00002 per share, on a one-for-one basis in connection with the First Merger (the “Sponsor Share Conversion”).
Notwithstanding the foregoing, if (i) after completion of the Sponsor Share Forfeiture, the First Merger does not occur and the
Business Combination Agreement is terminated, or (ii) after completion of the First Merger, the Second Merger does not occur and
the Business Combination Agreement is terminated, each of SPAC, Sponsor and the Company shall take all such actions that are necessary,
proper or advisable under applicable Laws such that Sponsor shall, to the fullest extent possible, be returned to the position in which

that notwithstanding the foregoing, any amendment or modification to this Agreement that would have a disproportionately adverse effect
on any party’s rights hereunder in any material respect shall require the prior written consent of such party.


 


5.9.            Counterparts.
This Agreement may be executed in multiple counterparts (including by electronic means), each of which shall be deemed an original, and
all of which together shall constitute the same instrument, but only one of which need be produced.


 






    15


     


    

 


5.10.          Termination.
This Agreement shall automatically terminate upon the earliest of (i) the First Merger Effective Time (provided, however,
that upon such termination, Article III, Article IV and Article V shall survive indefinitely), (ii) the termination
of the Business Combination Agreement in accordance with its terms and (iii) the 270th day after the date hereof (and if such 270th
day shall not be a Business Day, then the next following Business Day), or such later date as otherwise agreed in writing by the Consent
Parties, and upon such termination, no party shall have any liability hereunder other than for its actual fraud or for its willful and
material breach of this Agreement prior to such termination. Each Shareholder shall have the right to elect, in his, her or its sole
discretion, to terminate its own obligations under Article II of this Agreement if the Business Combination Agreement is amended
without the prior written consent of such Shareholder such that, after giving effect to all such amendments, the consideration payable
or issuable to such Shareholder under the Business Combination Agreement is decreased (either in terms of share number or ownership percentage)
or the form of consideration is changed, including any change to the Share Consolidation Factor or the terms of the Share Consolidation.
