to time on or after the date the Company consummates the Business Combination, (i) the Holders of at least thirty percent (30%) in interest
of the then-outstanding number of Registrable Securities or (ii) Cantor and its permitted designees (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)
to the Company, 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 reasonably practicable, but not more than forty five (45) days
immediately after the Company’s receipt of the Demand Registration, the Registration of all Registrable Securities requested by
the Demanding Holders and Requesting Holders pursuant to such 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, including one (1) Demand Registration on behalf of Cantor and its designees; 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 for resale on behalf of the Requesting Holders in such Form S-1 Registration have been sold,
in accordance with Section 3.1 of this Agreement.


 


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.


 


2.1.4        Reduction
of Underwritten Offering. If the managing Underwriter(s) 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 for its own account 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 Demanding Holder and Requesting Holder (if
any) has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Demanding
Holders and Requesting 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 desires to sell for its own account, which can be sold without exceeding the Maximum Number of Securities; and (iii) third,
to the extent that the 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 for resale in a Registration pursuant
to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities.

of the Requesting Holders (if any), pursuant to a Registration under subsection 2.1.1 shall have the right to withdraw from a Registration
pursuant to such Demand Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter(s) (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.


 


2.2           Piggyback
Registration.


 


2.2.1        Piggyback
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, for its own account or for the account of shareholders of the Company (or by
the Company and by the shareholders of the Company including, without limitation, pursuant to Section 2.1 hereof), other than
a Registration Statement (i) filed in connection with any employee share 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 give written notice of such
proposed filing to all of the Holders of Registrable Securities as soon as reasonably practicable but not less than ten (10) days
before the anticipated 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(s), if any,
in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to register the resale 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(s) 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
        Reduction of Piggyback Registration. If the managing Underwriter(s) in an
Underwritten Registration that is to be a Piggyback Registration, in good faith, advises the Company and the Holders of Registrable
Securities participating in the Piggyback Registration in writing that the dollar amount or number of the Ordinary Shares that the
Company desires to sell, taken together with (i) the 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 (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 for its own account, 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 the resale of their Registrable Securities pursuant to subsection 2.2.1 hereof, Pro Rata, 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;


 


(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
the resale of their Registrable Securities pursuant to subsection 2.2.1, pro rata based on the 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 for its own account, 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), the Ordinary Shares or other equity securities for the account of other persons or entities that
the Company is obligated to register for resale pursuant to separate written contractual arrangements with such persons or entities, which
can be sold without exceeding the Maximum Number of Securities.


 






    


     


    

 


2.2.3
        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(s) (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the
Registration Statement 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.


 


2.2.4        Unlimited
Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to Section 2.2 hereof shall
not be counted as a Registration pursuant to a Demand Registration effected under Section 2.1 hereof.


 


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, pursuant to Rule 415 under the Securities Act (or any
successor rule promulgated thereafter by the 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 (“Form S-3”), or if the
Company is ineligible to use Form S-3, on Form S-1; 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 reasonably 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 register the resale of 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 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 $10,000,000. The Company shall maintain
each registration statement pursuant to this Section 2.3 (a “Shelf”) in accordance with the terms
hereof, and shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements as may be
necessary to keep such Shelf continuously effective, available for use and in compliance with the provisions of the Securities Act
until such time as there are no longer any Registrable Securities included on such Shelf. In the event the Company files a Shelf on
Form S-1, the Company shall use its commercially reasonable efforts to convert the Form S-1 to a Form S-3 as soon as
reasonably practicable after the Company is eligible to use Form S-3. Registrations effected pursuant to this Section 2.3 shall
not be counted as Demand Registrations effected pursuant to Section 2.1.


 






    


     


    

 


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 materially 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 the Chairman of the Board stating that in the good faith judgment of the Board it would be materially 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, no Registration shall be effected or permitted and no Registration Statement shall
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.

        prepare and file with the Commission such amendments and post-effective amendments to the
Registration Statement, and such supplements to the Prospectus, as may be reasonably requested by the majority in interest of the
Holders with Registrable Securities registered for resale 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 Underwriter(s),
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 Underwriter(s) and the Holders of Registrable Securities included in such Registration
or the legal counsel for any such Holders may reasonably 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;


 


3.1.5        cause
all such Registrable Securities to be listed on each securities exchange or automated quotation system on which similar securities issued
by the Company are then listed;


 


3.1.6        provide
a transfer agent or warrant agent, as applicable, and registrar for all such Registrable Securities no later than the effective date of
such Registration Statement;


 


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 Underwriter(s), if any, and any attorney or accountant retained by such Holders or Underwriter(s)
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 Underwriter(s) 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(s) 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 Underwriter(s), if any, covering such legal matters with respect to the Registration in respect of which such opinion is being
given as the participating 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;


 


3.1.13        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(s) 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 (or any successor rule promulgated
thereafter by the Commission);


 


3.1.15        if
the Registration involves the Registration of the resale of the 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(s) 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 participating 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 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 reasonably practicable after the time of such notice), or until 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.


 


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 (or any successor rule promulgated thereafter by the Commission), 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.


 






    


     


    

 


3.5         Limitations
on Registration Rights. Notwithstanding anything herein to the contrary, (i) neither Cantor nor its designees may exercise their rights
under Sections 2.1 and 2.2 hereunder after five (5) and seven (7) after the effective date of the registration statement relating to the
Company’s initial public offering, respectively, and (ii) Cantor may not exercise their rights under Section 2.1 more than one time.


 


ARTICLE IV 


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, 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 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 furnished in writing to the Company by such Holder expressly
for use therein. The Company shall indemnify the Underwriter(s), their officers and directors and each person who controls such Underwriter(s)
(within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the
Holder.


 


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 and officers and agents and each person who controls the Company (within the meaning of the
Securities Act) against any losses, claims, damages, liabilities and out-of-pocket expenses (including, without limitation,
reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement,
Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any 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 Underwriter(s), their officers, directors and each person who controls such Underwriter(s) (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.


 


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 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 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 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.


 






    


     


    

 


ARTICLE V


MISCELLANEOUS

given, served, sent, and received, in the case of mailed notices, on the third Business Day following the date on which it is mailed and,
in the case of notices delivered by courier service, hand delivery, electronic mail, telecopy, telegram or facsimile, at such time as
it is delivered to the addressee (with the delivery receipt or the affidavit of messenger) or at such time as delivery is refused by the
addressee upon presentation. Any notice or communication under this Agreement must be addressed, if to the Company, to: Endurance Acquisition
Corp., 630 Fifth Avenue, 20th Floor, New York, NY 10111, Attention: Richard Davis, Chief Executive Officer, and, if to any
Holder, at such Holder’s address or facsimile number as set forth in the Company’s books and records. Any party may change
its address for notice at any time and from time to time by written notice to the other parties hereto, and such change of address shall
become effective thirty (30) calendar days after delivery of such notice as provided in this Section 5.1.


 


5.2           Assignment;
No Third Party Beneficiaries.


 


5.2.1       This
Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or
in part.


 


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, no Holder may assign
or delegate such Holder’s rights, duties or obligations under this Agreement, in whole or in part, except in connection with a transfer
of Registrable Securities by such Holder to a Permitted Transferee.


 






    


     


    

 


5.2.3        This
Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties and its successors and
the permitted assigns of the Holders, which shall include Permitted Transferees.


 


5.2.4        This
Agreement shall not confer any rights or benefits on any persons that are not parties hereto, other than as expressly set forth in this
Agreement and Section 5.2 hereof.


 


5.2.5        No
assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company
unless and until the Company shall have received (i) written notice of such assignment as provided in Section 5.1 hereof
and (ii) the written agreement of the assignee, in a form reasonably satisfactory to the Company, to be bound by the terms and provisions
of this Agreement (which may be accomplished by an addendum or certificate of joinder to this Agreement). Any transfer or assignment made
other than as provided in this Section 5.2 shall be null and void.


 


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


  


5.4        Governing
Law; Venue. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES EXPRESSLY AGREE
THAT THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK AS APPLIED TO AGREEMENTS AMONG NEW YORK
RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN NEW YORK, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION.


 


5.5        Amendments
and Modifications. Upon the written consent of the Company and the Holders of at least a majority in interest of the then outstanding
Registrable Securities (which majority interest must include Cantor if such amendment or modification affects in any way the rights of
Cantor hereunder), compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any of
such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing,
any amendment hereto or waiver hereof that adversely affects one Holder, solely in its capacity as a holder of capital 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.


 






    


     


    

 


5.6
        Other Registration Rights. The Company represents and warrants that no person,
other than a Holder of Registrable Securities, has any right to require the Company to register the offer, sale or resale of any
securities of the Company for sale or to include such securities 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. Further, the Company represents and warrants that
this Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions and in the event of
a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.


 


5.7        Term.
This Agreement shall terminate with respect to any Holder on the date that such Holder no longer holds any Registrable Securities. The
provisions of Section 3.5 and Article IV shall survive any termination.
