2. REGISTRATION
RIGHTS.


 


2.1 Demand
Registration.


 


2.1.1 Request
for Registration. At any time and from time to time on or after the date that the Company consummates a Business Combination
with respect to the Founder Shares, Private Warrants and Working Capital Loan Securities (or underlying securities), the holders
of a majority-in-interest of such Founder Shares, Private Warrants and Working Capital Loan Securities (or underlying securities),
or other Registrable Securities, as the case may be, the Investors, officers or directors of the Company or their affiliates,
or the transferees of the Investors, may make a written demand for registration under the Securities Act of all or part of their
Founder Shares and Private Warrants or Working Capital Loan Securities (or underlying securities or other 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 all holders of Registrable Securities of the 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 three (3) Demand Registrations
under this Section 2.1.1 in respect of all Registrable Securities.


 






    2


     


    

 


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 stockholders 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; (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. 


 


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.


 






    3


     


    

 


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 Ordinary Shares, if any, as to which registration has been demanded pursuant
to separate written contractual arrangements with persons or entities 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 stockholders
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) the Ordinary Shares or other securities that the Company
desires to sell that can be sold without exceeding the Maximum Number of Shares; (B) 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, which can be sold without exceeding the Maximum Number of Shares; and (C) 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; and


 


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 which 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, which 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. 


 


2.3 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.

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
the President 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 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 the immediately preceding proviso more than
once in any 365-day period in respect of a Demand Registration hereunder.

statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements
therein not misleading, and promptly make available to the holders of Registrable Securities included in such Registration Statement
any such supplement or amendment; except that before filing with the Commission a Registration Statement or prospectus or any

Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions;

to Suspend Distribution. Upon receipt of any notice from the Company of the happening of any event of the kind described in
Section 3.1.4(iv), or, in the case of a resale registration on Form S-3 pursuant to Section 2.3 hereof, upon any suspension by
the Company, pursuant to a written insider trading compliance program adopted by the Company’s Board of Directors, of the
ability of all “insiders” covered by such program to transact in the Company’s securities because of the existence
of material non-public information, each holder of Registrable Securities included in any registration shall immediately discontinue
disposition of such Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such

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 whether or not any such person is a party to any such claim or action and including any and all legal and
other expenses incurred in giving testimony or furnishing documents in response to a subpoena or otherwise; 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. Subject to the limitations set forth in Section 4.4.3 hereof, 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 advice 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) with respect to any action shall be entitled to
contribution in such action from any person who was not guilty of such fraudulent misrepresentation.


 


5. UNDERWRITING
AND DISTRIBUTION.


 


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 Rule may be amended from time to time, or
any similar rule or regulation hereafter adopted by the Commission. 


 


6. MISCELLANEOUS.


 


6.1 Other
Registration Rights. The Company represents and warrants that no person, other than the holders of the Registrable Securities,
has any right to require the Company to register any shares of the Company’s capital stock for sale or to include shares
of the Company’s capital stock in any registration filed by the Company for the sale of shares of capital stock for its
own account or for the account of any other person.

Securities hereunder may be freely assigned or delegated by such holder of Registrable Securities in conjunction with and to the
extent of any transfer of Registrable Securities by any such holder. This Agreement and the provisions hereof shall be binding
upon and shall inure to the benefit of each of the parties, to the permitted assigns of the Investors or holder of Registrable
Securities 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.

then such notice shall be deemed given on the next business day. Notice otherwise sent as provided herein shall be deemed given
