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, on no more than two occasions, in each case make a written demand 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 provisos 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.


 






    3


     


    

 


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;


 






    4


     


    

 


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
the Ordinary Shares or other securities comprised of Registrable Securities, Pro Rata, as to which registration has been requested pursuant
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.


 


3. REGISTRATION PROCEDURES.

Whenever the Company is required to effect the registration of any Registrable Securities pursuant to Section 2, the Company shall use
its best efforts to effect the registration and sale of such Registrable Securities in accordance with the intended method(s) of distribution
thereof as expeditiously as practicable, and in connection with any such request:


 


3.1.1 Filing Registration
Statement. The Company shall use its best efforts to, as expeditiously as possible after receipt of a request for a Demand Registration
pursuant to Section 2.1, prepare and file with the Commission a Registration Statement on any form for which the Company then qualifies

Registration Statement to become effective and use its best efforts to keep it effective for the period required by Section 3.1.3; provided,
however, that the Company shall have the right to defer any Demand Registration for up to thirty (30) days, and any Piggy-Back Registration
for such period as may be applicable to deferment of any demand registration to which such Piggy-Back Registration relates, in each case
if the Company shall furnish to the holders a certificate signed by Chief Executive Officer or Chairman of the Company stating that, in
the good faith judgment of the Board of Directors of the Company, it would be materially detrimental to the Company and its shareholders
for such Registration Statement to be effected at such time; provided further, however, that the Company shall not have the right to exercise
the right set forth in this provision more than once in any 365-day period in respect of a Demand Registration hereunder.

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-[______]), 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.

hereto other than as expressly set forth in Article 4 and this Section 6.2. Any additional holder of Registrable Securities may become
