Demand Registration.


 


2.1.1       
Request for Registration. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, at any time and from
time to time on or after the date the Company consummates the initial Business Combination, the Holders of at least thirty percent
(30%) in interest of the then outstanding number of Registrable Securities (the “Demanding
Holders”) may make a written demand for Registration under the Securities Act of all or part of their Registrable
Securities, which written demand shall describe the amount and type of securities to be included in such Registration and the intended
method(s) of distribution thereof (such written demand a “Demand Registration”).
The Company shall, within ten (10) days of the Company’s receipt of the Demand Registration, notify, in writing, all other
Holders of Registrable Securities of such demand, and each Holder of Registrable Securities who thereafter wishes to include all
or a portion of such Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder
that includes all or a portion of such Holder’s Registrable Securities in such Registration, a “Requesting
Holder”) shall so notify the Company, in writing, within five (5) days after the receipt by the Holder of the
notice from the Company. Upon receipt by the Company of any such written notification from a Requesting Holder(s), such Requesting
Holder(s) shall be entitled to have their Registrable Securities included in a Registration pursuant to a Demand Registration and
the Company shall effect, as soon thereafter as practicable, the Registration of all Registrable Securities requested by the Demanding
Holder(s) and Requesting Holder(s) pursuant to such Demand Registration, including by filing a Registration Statement relating
thereto as soon as practicable, but not more than forty five (45) days immediately after the Company’s receipt of the
Demand Registration. Under no circumstances shall the Company be obligated to effect more than an aggregate of three (3) Registrations
pursuant to a Demand Registration under this subsection 2.1.1 with respect to any or all Registrable Securities; provided,
however, that a Registration shall not be counted for such purposes unless a Form S-1 or any similar long-form registration
statement that may be available at such time (“Form S-1”) has become
effective and all of the Registrable Securities requested by the Requesting Holders to be registered on behalf of the Requesting
Holders in such Form S-1 Registration have been sold, in accordance with Section 3.1 of this Agreement.



    5


     


    


2.1.2       
Effective Registration. Notwithstanding the provisions of subsection 2.1.1 above or any other part of this
Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration
Statement filed with the Commission with respect to a Registration pursuant to a Demand Registration has been declared effective
by the Commission and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided,
further, that if, after such Registration Statement has been declared effective, an offering of Registrable Securities in
a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission,
federal or state court or any other governmental agency the Registration Statement with respect to such Registration shall 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 initiating such Demand Registration thereafter affirmatively elect to
continue with such Registration and accordingly notify the Company in writing, but in no event later than five (5) days, of such
election; provided, further, that the Company shall not be obligated or required to file another Registration Statement
until the Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration
becomes effective or is subsequently terminated.


 


2.1.3       
Underwritten Offering. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, if a majority-in-interest
of the Demanding Holders so advise the Company as part of their Demand Registration that the offering of the Registrable Securities
pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder
or Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s
participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten
Offering to the extent provided herein. All such Holders proposing to distribute their Registrable Securities through an Underwritten
Offering under this subsection 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected
for such Underwritten Offering by the majority-in-interest of the Demanding Holders initiating the Demand Registration.



    6


     


    


2.1.4       
Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Registration pursuant
to a Demand Registration, in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing
that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire
to sell, taken together with all other Ordinary Shares or other equity securities that the Company desires to sell and the Ordinary
Shares, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back registration
rights held by any other shareholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities
that can be sold in the Underwritten 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 such securities, as applicable,
the “Maximum Number of Securities”), then the Company shall include in
such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting Holders
(if any) (pro rata based on the respective number of Registrable Securities that each such Holder has requested be included in
such Underwritten Registration and the aggregate number of Registrable Securities that such Holders have requested be included
in such Underwritten Registration (such proportion is referred to herein as “Pro Rata”))
that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of
Securities has not been reached under the foregoing clause (i), the Ordinary Shares or other equity securities that the Company

Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the Ordinary Shares or other equity
securities of other persons or entities that the Company is obligated to register in a Registration pursuant to separate written
contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities.

to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Registration prior to the
effectiveness of the Registration Statement filed with the Commission with respect to the Registration of their Registrable Securities
pursuant to such Demand Registration. Notwithstanding anything to the contrary in this Agreement, (i) the Company may effect any
Underwritten Registration pursuant to any then effective Registration Statement, including a Form S-3, that is then available for
such offering and (ii) the Company shall be responsible for the Registration Expenses incurred in connection with a Registration
pursuant to a Demand Registration prior to its withdrawal under this subsection 2.1.5.



    7


     


    


2.2         
Piggyback Registration.


 


2.2.1      
Piggyback Rights. If, at any time on or after the date the Company consummates an initial 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, for its own account or
for the account of shareholders of the Company (or by the Company and by the shareholders of the Company), other than a Registration

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 give written notice of such proposed

filing date of such Registration Statement, which notice shall (A) 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,
in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to register the sale of such number
of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such written notice (such
Registration a “Piggyback Registration”). The Company shall, in good
faith, cause such Registrable Securities to be included in such Piggyback 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 by
the Holders pursuant to this subsection 2.2.1 to be included in a Piggyback Registration on the same terms and conditions as any
similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable
Securities in accordance with the intended method(s) of distribution thereof. All such Holders proposing to distribute their Registrable
Securities through an Underwritten Offering under this subsection 2.2.1 shall enter into an underwriting agreement in customary
form with the Underwriter(s) selected for such Underwritten Offering by the Company.


 


2.2.2

arrangements with persons or entities other than the Holders of Registrable Securities hereunder (ii) the Registrable Securities
as to which registration has been requested pursuant to Section 2.2 hereof, and (iii) the Ordinary Shares, if any, as to which
Registration has been requested pursuant to separate written contractual piggy-back registration rights of other shareholders of
the Company, exceeds the Maximum Number of Securities, then:


 


(a)               
If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A)
first, the Ordinary Shares or other equity securities that the Company desires to sell, which can be sold without exceeding the
Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing
clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to
subsection 2.2.1 hereof, pro rata, based on the respective number of Registrable Securities that each Holder has so requested
exercising its rights to register its Registrable Securities pursuant to subsection 2.2.1 hereof, which can be sold without
exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached
under the foregoing clauses (A) and (B), the Ordinary Shares, if any, as to which Registration has been requested pursuant to written
contractual piggy-back registration rights of other shareholders of the Company, which can be sold without exceeding the Maximum
Number of Securities;



    8


     


    


(b)              
If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then
the Company shall include in any such Registration (A) first, the Ordinary Shares or other equity securities, if any, of such requesting
persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of
Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A),
the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection
2.2.1, pro rata, based on the respective number of Registrable Securities that each Holder has requested be included in such
Underwritten Registration and the aggregate number of Registrable Securities that the Holders have requested to be included in
such Underwritten Registration, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent
that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Ordinary Shares or other
equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D)
fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C),

Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback
Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any)

filed with the Commission with respect to such Piggyback Registration (or in the case of an Underwritten Registration pursuant
to Rule 415 under the Securities Act, at least two business days prior to the time of pricing of the applicable offering). The
Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate
written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback
Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in
this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration
prior to its withdrawal under this subsection 2.2.3.



    9


     


    


2.2.4

Commission), register the resale of any or all of their Registrable Securities on Form S-3 or any similar short-form registration
statement that may be available at such time pursuant to this Section 2.3 (“Form S-3”);
provided, however, that the Company shall not be obligated to effect such request through an Underwritten Offering. Within five
(5) days of the Company’s receipt of a written request from a Holder or Holders of Registrable Securities for a Registration
on Form S-3, the Company shall promptly give written notice of the proposed Registration on Form S-3 to all other Holders of Registrable
Securities, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s
Registrable Securities in such Registration on Form S-3 shall so notify the Company, in writing, within ten (10) days after the
receipt by the Holder of the notice from the Company. As soon as practicable thereafter, but not more than twelve (12) days after
the Company’s initial receipt of such written request for a Registration on Form S-3, the Company shall file a Registration
Statement relating to all or such portion of such Holder’s Registrable Securities as are specified in such written request,
together with all or such portion of Registrable Securities of any other Holder or Holders joining in such request as are specified
in the written notification given by such Holder or Holders; provided, however, that the Company shall not be obligated to effect
any such Registration pursuant to Section 2.3 hereof if (i) a Form S-3 is not available for such offering; or (ii) the Holders
of Registrable Securities, together with the Holders of any other equity securities of the Company entitled to inclusion in such
Registration, propose to sell the Registrable Securities and such other equity securities (if any) at any aggregate price to the
public of less than $5,000,000.


 


2.4         
Restrictions on Registration Rights. If (A) during the period starting with the date sixty (60) days prior to the
Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after
the effective date of, a Company initiated Registration and provided that the Company has delivered written notice to the Holders
prior to receipt of a Demand Registration pursuant to subsection 2.1.1 and it continues to actively employ, in good faith, all
reasonable efforts to cause the applicable Registration Statement to become effective; (B) the Holders have requested an Underwritten
Registration and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer;
or (C) in the good faith judgment of the Board, such Registration would be seriously detrimental to the Company and the Board concludes
as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case, the Company
shall furnish to such Holders a certificate signed by a Co-Chairman of the Board, the chief executive officer of the Company or
chief financial officer of the Company stating that in the good faith judgment of the Board it would be seriously detrimental to
the Company for such Registration Statement to be filed in the near future and that it is therefore essential to defer the filing
of such Registration Statement. In such event, the Company shall have the right to defer such filing for a period of not more than
thirty (30) days; provided, however, that the Company shall not defer its obligation in this manner more than once in any 12-month
period. Notwithstanding anything to the contrary contained in this Agreement, the Company shall not be required to effect or permit
any Registration or cause any Registration Statement to become effective, with respect to any Registrable Securities held by any
Holder, until after the expiration of the Founder Shares Lock-Up Period or the Private Placement Lock-Up Period, as the case may
be.

registered on such Registration Statement or any Underwriter of Registrable Securities or as may be required by the rules, regulations
or instructions applicable to the registration form used by the Company or by the Securities Act or rules and regulations thereunder
to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in
accordance with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus;


 


3.1.3       
prior to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish without charge to
the Underwriters, if any, and the Holders of Registrable Securities included in such Registration, and such Holders’ legal
counsel, copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement
(in each case including all exhibits thereto and documents incorporated by reference therein), the Prospectus included in such
Registration Statement (including each preliminary Prospectus), and such other documents as the Underwriters and the Holders of
Registrable Securities included in such Registration or the legal counsel for any such Holders may request in order to facilitate
the disposition of the Registrable Securities owned by such Holders;


 


3.1.4       
prior to any public offering of Registrable Securities, use its best efforts to (i) register or qualify the Registrable
Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in
the United States as the Holders of Registrable Securities included in such Registration Statement (in light of their intended
plan of distribution) may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration
Statement to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business
and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Holders
of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities
in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business
in any jurisdiction where it would not otherwise be required to qualify or take any action to which it would be subject to general
service of process or taxation in any such jurisdiction where it is not then otherwise so subject;

3.1.7      advise each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of
the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation
or threatening of any proceeding for such purpose and promptly use its reasonable best efforts to prevent the issuance of any stop
order or to obtain its withdrawal if such stop order should be issued;


 


3.1.8      at least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to
such Registration Statement or Prospectus furnish a copy thereof to each seller of such Registrable Securities or its counsel;


 


3.1.9      notify the Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under
the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement,
as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.4 hereof;


 


3.1.10   
permit a representative of the Holders, the Underwriters, if any, and any attorney or accountant retained by such Holders
or Underwriter to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause
the Company’s officers, directors and employees to supply all information reasonably requested by any such representative,
Underwriter, attorney or accountant in connection with the Registration; provided, however, that such representatives
or Underwriters enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to
the release or disclosure of any such information;


 


3.1.11   
obtain a “cold comfort” letter from the Company’s independent registered public accountants in the event
of an Underwritten Registration, in customary form and covering such matters of the type customarily covered by “cold comfort”
letters as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating
Holders;


 


3.1.12   
on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such
date, of counsel representing the Company for the purposes of such Registration, addressed to the Holders, the placement agent
or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of
which such opinion is being given as the Holders, placement agent, sales agent, or Underwriter may reasonably request and as are
customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority in interest of
the participating Holders;



    12

in the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing Underwriter of such offering;


 


3.1.14   
make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of
at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective
date of the Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;


 


3.1.15   
if the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $25,000,000,
use its reasonable efforts to make available senior executives of the Company to participate in customary “road show”
presentations that may be reasonably requested by the Underwriter in any Underwritten Offering; and


 


3.1.16   
otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the
Holders, in connection with such Registration.


 


3.2         
Registration Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged
by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such
as Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the
definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the
Holders.


 


3.3         
Requirements for Participation in Underwritten Offerings. No person may participate in any Underwritten Offering
for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees
to sell such person’s securities on the basis provided in any underwriting arrangements approved by the Company and (ii)
completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements
and other customary documents as may be reasonably required under the terms of such underwriting arrangements.


 


3.4          Suspension of Sales; Adverse Disclosure. Upon receipt of written notice from the Company that a Registration Statement
or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until
he, she or it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that
the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice),
or until he, she or it is advised in writing by the Company that the use of the Prospectus may be resumed. If the filing, initial
effectiveness or continued use of a Registration Statement in respect of any Registration at any time would require the Company
to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable
to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action
to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period
of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose.
In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their
receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or
offer to sell Registrable Securities. The Company shall immediately notify the Holders of the expiration of any period during which
it exercised its rights under this Section 3.4.



    13


     


    


3.5         
Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it
shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file
within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections
13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings. The Company
further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from
time to time to enable such Holder to sell Ordinary Shares held by such Holder without registration under the Securities Act within
the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including providing any legal opinions.
Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as
to whether it has complied with such requirements.

INDEMNIFICATION AND CONTRIBUTION


 


4.1         
Indemnification.


 


4.1.1       
The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers, directors
and agents and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages,
liabilities and out-of-pocket expenses (including without limitation reasonable outside attorneys’ fees) resulting from any
untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus
or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein
or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information
or affidavit so furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters,
their officers and directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same
extent as provided in the foregoing with respect to the indemnification of the Holder.



    14


     


    


4.1.2       
In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder
shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection
with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors,
officers and agents and each person who controls the Company (within the meaning of the Securities Act) against all losses, claims,
damages, liabilities and out-of-pocket expenses (including without limitation reasonable outside attorneys’ fees) resulting
from any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary
Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or
omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided,
however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities,
and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received
by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities
shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning
of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.


 


4.1.3       
Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim
with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s
right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless
in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties
may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability
for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An
indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees
and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless
in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other
of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party,
consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money
(and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include
as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability
in respect to such claim or litigation.


 


4.1.4       
The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation
made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall
survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees
to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s
or such Holder’s indemnification is unavailable for any reason.



    15


     


    


4.1.5       
If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and out-of-pocket expenses referred
to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable
by the indemnified party as a result of such losses, claims, damages, liabilities and out-of-pocket expenses in such proportion
as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant
equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to,
among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified
party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity
to correct or prevent such action; provided, however, that the liability of any Holder under this subsection 4.1.5
shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The
amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include,
subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees,
charges or out-of-pocket expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties
hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 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 this subsection 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution pursuant to this subsection 4.1.5 from any person who was not guilty of
such fraudulent misrepresentation.

5.2.2       
Prior to the expiration of the Founder Shares Lock-up Period or the Private Placement Lock-up Period, as the case may be,

of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth

that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in his, her
or its capacity as a holder of the shares of the Company, in a manner that is materially different from the other Holders (in such
capacity) shall require the consent of the Holder so affected. No course of dealing between any Holder or the Company and any other
party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement
shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or
remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder
or thereunder by such party.



    17

Other Registration Rights. The Company represents and warrants that no person, other than a Holder of Registrable

of the Company in any Registration filed by the Company for the sale of securities for its own account or for the account of any
other person, other than pursuant to the Forward Purchase Agreement. Further, the Company represents and warrants that this Agreement
