	 	2.	REGISTRATION RIGHTS.




 


	 	2.1	Demand Registration.




 





2.1.1
Request for Registration. At any time and from time to time on or after (i) the date that the Company consummates a Business Combination
with respect to the Private Units (or underlying Ordinary Shares), Over-Allotment Units (or underlying Ordinary Shares) and Working Capital
Loan Securities or (ii) three months prior to the Release Date with respect to all other Registrable Securities, the holders of a majority-in-interest
of the Registrable Securities, as the case may be, held by the Investors, officers or directors of the Company or their affiliates, or
the transferees of the Investors, may make a written demand, on no more than two occasions, for registration under the Securities Act
of all or part of their Registrable Securities, as the case may be (a “Demand Registration”). Any demand for
a Demand Registration shall specify the number of shares of Registrable Securities proposed to be sold and the intended method(s) of
distribution thereof. The Company will notify, in writing, all holders of Registrable Securities of the demand, with ten (10) days of
the Company’s receipt of such demand, and each holder of Registrable Securities who wishes to include all or a portion of such
holder’s Registrable Securities in the Demand Registration (each such holder including shares of Registrable Securities in such
registration, a “Demanding Holder”) shall so notify the Company within fifteen (15) days after the receipt
by the holder of the notice from the Company. Upon any such request, the Demanding Holders shall be entitled to have their Registrable
Securities included in the Demand Registration, subject to Section 2.1.4 and the provisions set forth in Section 3.1.1. The Company shall
not be obligated to effect more than an aggregate of two (2) Demand Registrations under this Section 2.1.1 in respect of all Registrable
Securities.


 


2.1.2
Effective Registration. A registration will not count as a Demand Registration until the Registration Statement filed with the
Commission with respect to such Demand Registration has been declared effective and the Company has complied with all of its obligations
under this Agreement with respect thereto; provided, however, that if, after such Registration Statement has been declared effective,
the offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop order or injunction of the Commission
or any other governmental agency or court, the Registration Statement with respect to such Demand Registration will be deemed not to
have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and
(ii) a majority-in-interest of the Demanding Holders thereafter elect to continue the offering; provided, further, that the Company shall
not be obligated to file a second Registration Statement until a Registration Statement that has been filed is counted as a Demand Registration
or is terminated.


 


2.1.3
Underwritten Offering. If a majority-in-interest of the Demanding Holders so elect and such holders so advise the Company as part
of their written demand for a Demand Registration, the offering of such Registrable Securities pursuant to such Demand Registration shall
be in the form of an underwritten offering. In such event, the right of any holder to include its Registrable Securities in such registration
shall be conditioned upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable
Securities in the underwriting to the extent provided herein. All Demanding Holders proposing to distribute their Registrable Securities
through such underwriting shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected
for such underwriting by a majority-in-interest of the holders initiating the Demand Registration.


 




    	 



     


    




 


2.1.4
Reduction of Offering. If the managing Underwriter or Underwriters for a Demand Registration that is to be an underwritten offering
advises the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the
Demanding Holders desire to sell, taken together with all other Ordinary Shares or other securities which the Company desires to sell
and the Ordinary Shares, if any, as to which registration has been requested pursuant to written contractual piggy-back registration
rights held by other shareholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum number of shares that
can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability
of success of such offering (such maximum dollar amount or maximum number of shares, as applicable, the “Maximum Number of
Shares”), then the Company shall include in such registration: (i) first, the Registrable Securities as to which Demand
Registration has been requested by the Demanding Holders (pro rata in accordance with the number of shares that each such Person has
requested be included in such registration, regardless of the number of shares held by each such Person (such proportion is referred
to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Shares; (ii) second, to
the extent that the Maximum Number of Shares has not been reached under the foregoing clause (i), the Ordinary Shares or other securities
that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; and (iii) third, to the extent that
the Maximum Number of Shares has not been reached under the foregoing clauses (i) and (ii), the Ordinary Shares or other securities for
the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons
and that can be sold without exceeding the Maximum Number of Shares.


 


2.1.5
Withdrawal. If a majority-in-interest of the Demanding Holders disapprove of the terms of any underwriting or are not entitled
to include all of their Registrable Securities in any offering, such majority-in-interest of the Demanding Holders may elect to withdraw
from such offering by giving written notice to the Company and the Underwriter or Underwriters of their request to withdraw prior to
the effectiveness of the Registration Statement filed with the Commission with respect to such Demand Registration. If the majority-in-interest
of the Demanding Holders withdraws from a proposed offering relating to a Demand Registration, then such registration shall not count
as a Demand Registration provided for in Section 2.1. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred
by the holders of Registrable Securities in connection with such Demand Registration as provided in Section 3.3.


 




    	 



     


    




 


	 	2.2	Piggy-Back Registration.




 


2.2.1
Piggy-Back Rights. If at any time on or after the date the Company consummates a Business Combination the Company proposes to
file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations
exercisable or exchangeable for, or convertible into, equity securities, by the Company for its own account or for shareholders of the
Company for their account (or by the Company and by shareholders of the Company including, without limitation, pursuant to Section 2.1),
other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange
offer or offering of securities solely to the Company’s existing shareholders, (iii) for an offering of debt that is convertible
into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall (x) give written notice of such
proposed filing to the holders of Registrable Securities as soon as practicable but in no event less than ten (10) days before the anticipated
filing date, which notice shall describe the amount and type of securities to be included in such offering, the intended method(s) of
distribution, and the name of the proposed managing Underwriter or Underwriters, if any, of the offering, and (y) offer to the holders
of Registrable Securities in such notice the opportunity to register the sale of such number of shares of Registrable Securities as such
holders may request in writing within five (5) days following receipt of such notice (a “Piggy-Back Registration”).
The Company shall cause such Registrable Securities to be included in such registration and shall use its best efforts to cause the managing
Underwriter or Underwriters of a proposed underwritten offering to permit the Registrable Securities requested to be included in a Piggy-Back
Registration on the same terms and conditions as any similar securities of the Company and to permit the sale or other disposition of
such Registrable Securities in accordance with the intended method(s) of distribution thereof. All holders of Registrable Securities
proposing to distribute their securities through a Piggy-Back Registration that involves an Underwriter or Underwriters shall enter into
an underwriting agreement in customary form with the Underwriter or Underwriters selected for such Piggy-Back Registration.


 


2.2.2
Reduction of Offering. If the managing Underwriter or Underwriters for a Piggy-Back Registration that is to be an underwritten
offering advises the Company and the holders of Registrable Securities in writing that the dollar amount or number of Ordinary Shares
which the Company desires to sell, taken together with the Ordinary Shares, if any, as to which registration has been demanded pursuant
to written contractual arrangements with persons other than the holders of Registrable Securities hereunder, the Registrable Securities
as to which registration has been requested under this Section 2.2, and the Ordinary Shares, if any, as to which registration has been
requested pursuant to the written contractual piggy-back registration rights of other shareholders of the Company, exceeds the Maximum
Number of Shares, then the Company shall include in any such registration:


 


a)
If the registration is undertaken for the Company’s account: (A) first, the Ordinary Shares or other securities that the Company
desires to sell that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of
Shares has not been reached under the foregoing clause (A), the Ordinary Shares or other securities, if any, comprised of Registrable
Securities, as to which registration has been requested pursuant to the applicable written contractual piggy-back registration rights
of such security holders, Pro Rata, that can be sold without exceeding the Maximum Number of Shares; and (C) third, to the extent that
the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), the Ordinary Shares or other securities for
the account of other persons that the Company is obligated to register pursuant to written contractual piggy-back registration rights
with such persons and that can be sold without exceeding the Maximum Number of Shares;


 




    	 



     


    




 


b)
If the registration is a “demand” registration undertaken at the demand of persons other than either the holders of Registrable
Securities, (A) first, the Ordinary Shares or other securities for the account of the demanding persons that can be sold without exceeding
the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause
(A), the Ordinary Shares or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of
Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), collectively

to the terms hereof, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, to the extent that the Maximum
Number of Shares has not been reached under the foregoing clauses (A), (B) and (C), the Ordinary Shares or other securities for the account
of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, that can be
sold without exceeding the Maximum Number of Shares.


 


2.2.3
Withdrawal. Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable
Securities in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness
of the Registration Statement. The Company (whether on its own determination or as the result of a withdrawal by persons making a demand
pursuant to written contractual obligations) may withdraw a Registration Statement at any time prior to the effectiveness of such Registration
Statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the holders of Registrable Securities
in connection with such Piggy-Back Registration as provided in Section 3.3.


 


2.2.4
Registrations on Form S-3. The holders of Registrable Securities may at any time and from time to time, request in writing that
the Company register the resale of any or all of such Registrable Securities on Form S-3 or any similar short-form registration which
may be available at such time (“Form S-3”); provided, however, that the Company shall not be obligated to effect
such request through an underwritten offering. Upon receipt of such written request, the Company will promptly give written notice of
the proposed registration to all other holders of Registrable Securities, and, as soon as practicable thereafter, effect the registration
of all or such portion of such holder’s or holders’ Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities or other securities of the Company, if any, of any other holder or holders joining
in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such registration pursuant to this Section 2.3: (i) if Form
S-3 is not available for such offering; or (ii) if the holders of the Registrable Securities, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities
(if any) at any aggregate price to the public of less than $500,000. Registrations effected pursuant to this Section 2.3 shall not be
counted as Demand Registrations effected pursuant to Section 2.1.

with the Company’s obligation to comply with Federal and applicable state securities laws.


 




    	 



     


    




 


	 	4.	INDEMNIFICATION AND CONTRIBUTION.




 


4.1
Indemnification by the Company. The Company agrees to indemnify and hold harmless each Investor and each other holder of Registrable
Securities, and each of their respective officers, employees, affiliates, directors, partners, members, attorneys and agents, and each
person, if any, who controls an Investor and each other holder of Registrable Securities (within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act) (each, an “Investor Indemnified Party”), from and against any expenses,
losses, judgments, claims, damages or liabilities, whether joint or several, arising out of or based upon any untrue statement (or allegedly
untrue statement) of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was
registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration
Statement, or any amendment or supplement to such Registration Statement, or arising out of or based upon any omission (or alleged omission)
to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by
the Company of the Securities Act or any rule or regulation promulgated thereunder applicable to the Company and relating to action or
inaction required of the Company in connection with any such registration; and the Company shall promptly reimburse the Investor Indemnified
Party for any legal and any other expenses reasonably incurred by such Investor Indemnified Party in connection with investigating and
defending any such expense, loss, judgment, claim, damage, liability or action; provided, however, that the Company will not be liable
in any such case to the extent that any such expense, loss, claim, damage or liability arises out of or is based upon any untrue statement
or allegedly untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus, final prospectus,
or summary prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company,
in writing, by such selling holder expressly for use therein. The Company also shall indemnify any Underwriter of the Registrable Securities,
their officers, affiliates, directors, partners, members and agents and each person who controls such Underwriter on substantially the
same basis as that of the indemnification provided above in this Section 4.1.


 


4.2
Indemnification by Holders of Registrable Securities. Each selling holder of Registrable Securities will, in the event that any
registration is being effected under the Securities Act pursuant to this Agreement of any Registrable Securities held by such selling
holder, indemnify and hold harmless the Company, each of its directors and officers and each Underwriter (if any), and each other selling
holder and each other person, if any, who controls another selling holder or such Underwriter within the meaning of the Securities Act,
against any losses, claims, judgments, damages or liabilities, whether joint or several, insofar as such losses, claims, judgments, damages
or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or allegedly untrue statement of a
material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities
Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or
supplement to the Registration Statement, or arise out of or are based upon any omission or the alleged omission to state a material
fact required to be stated therein or necessary to make the statement therein not misleading, if the statement or omission was made in
reliance upon and in conformity with information furnished in writing to the Company by such selling holder expressly for use therein,
and shall reimburse the Company, its directors and officers, and each other selling holder or controlling person for any legal or other
expenses reasonably incurred by any of them in connection with investigation or defending any such loss, claim, damage, liability or
action. Each selling holder’s indemnification obligations hereunder shall be several and not joint and shall be limited to the
amount of any net proceeds actually received by such selling holder.


 




    	 



     


    




 


4.3
Conduct of Indemnification Proceedings. Promptly after receipt by any person of any notice of any loss, claim, damage or liability
or any action in respect of which indemnity may be sought pursuant to Section 4.1 or 4.2, such person (the “Indemnified Party”)
shall, if a claim in respect thereof is to be made against any other person for indemnification hereunder, notify such other person (the
“Indemnifying Party”) in writing of the loss, claim, judgment, damage, liability or action; provided, however,
that the failure by the Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability
which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is
actually prejudiced by such failure. If the Indemnified Party is seeking indemnification with respect to any claim or action brought
against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent
that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel satisfactory to the
Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume control of the defense
of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently
incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however,
that in any action in which both the Indemnified Party and the Indemnifying Party are named as defendants, the Indemnified Party shall
have the right to employ separate counsel (but no more than one such separate counsel) to represent the Indemnified Party and its controlling
persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party
against the Indemnifying Party, with the fees and expenses of such counsel to be paid by such Indemnifying Party if, based upon the written
opinion of counsel of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual
or potential differing interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party,
consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified
Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such judgment or
settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.


 


	 	4.4	Contribution.




 


4.4.1
If the indemnification provided for in the foregoing Sections 4.1, 4.2 and 4.3 is unavailable to any Indemnified Party in respect of
any loss, claim, damage, liability or action referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified
Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage, liability or
action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in
connection with the actions or omissions which resulted in such loss, claim, damage, liability or action, as well as any other relevant
equitable considerations. The relative fault of any Indemnified Party and any Indemnifying Party shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by such Indemnified Party or such Indemnifying Party and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such statement or omission.


 




    	 



     


    




 


4.4.2
The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.4 were determined by pro
rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately
preceding Section 4.4.1.


 


4.4.3
The amount paid or payable by an Indemnified Party as a result of any loss, claim, damage, liability or action referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such
Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section
4.4, no holder of Registrable Securities shall be required to contribute any amount in excess of the dollar amount of the net proceeds
(after payment of any underwriting fees, discounts, commissions or taxes) actually received by such holder from the sale of Registrable
Securities which gave rise to such contribution obligation. No person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.


 


	 	5.	RULE 144.




 


5.1
Rule 144. The Company covenants that it shall file any reports required to be filed by it under the Securities Act and the Exchange
Act and shall take such further action as the holders of Registrable Securities may reasonably request, all to the extent required from
time to time to enable such holders to sell Registrable Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144 under the Securities Act, as such Rules may be amended from time to time, or any similar rule
or regulation hereafter adopted by the Commission. Upon the request of any holder of Registrable Securities, the Company shall deliver
to such Holder a written certification of a duly authorized officer as to (A) whether the Company has filed (i) all reports and other
materials required to be filed pursuant to Sections 13(a) or 15(d) of the Exchange Act, as applicable, during the preceding 12 months
(or for such shorter period that the Company was required to file such reports and materials), other than Current Reports on Form 8-K
and (ii) current “Form 10 information” (within the meaning of Rule 144 under the Securities Act) with the Commission reflecting
the Company’s status as an entity that is no longer an issuer described in paragraph (i)(1)(i) of Rule 144 under the Securities
Act and (B) the first date that the Company filed “Form 10 information” (within the meaning of Rule 144 under the Securities
Act) with the Commission.


 


	 	6.	MISCELLANEOUS.




 


6.1
Other Registration Rights. The Company represents and warrants that, except as disclosed in the Company’s registration statement
on Form S-1 (File No. 333-259031 ), no person, other than the holders of the Registrable Securities, has any right to require the
Company to register any of the Company’s share capital for sale or to include the Company’s share capital in any registration
filed by the Company for the sale of share capital for its own account or for the account of any other person.

or of any assignee of the Investors or holder of Registrable Securities. This Agreement is not intended to confer any rights or benefits
on any persons that are not party hereto other than as expressly set forth in Article 4 and this Section 6.2. Any additional holder of
Registrable Securities may become party to this Agreement by executing and delivering a joinder to the Company and the Sponsor in form
and substance reasonably satisfactory to the Company.


 


6.3
