and from time to time on or after the date the Company consummates the Business Combination, the Holders of at least a majority-in-interest
of the then-outstanding number of Registrable Securities (the “Demanding Holders”) may make a written
demand for Registration of at least fifteen percent (15%) of the then-outstanding number of 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 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; 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.


 


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 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 Common Stock or other equity securities that the Company desires to sell and Common Stock, if any,
as to which a Registration has been requested pursuant to separate written contractual piggy-back registration rights held by any
other stockholders 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 Registrable Securities of Holders exercising their
rights to register their Registrable Securities (Pro Rata) pursuant to subsection 2.2.1 hereof, without exceeding the
Maximum Number of Securities; (iii) third, to the extent that the Maximum Number of Securities has not been reached under
the foregoing clauses (i) and (ii), Common Stock or other equity securities that the Company desires to
sell, which can be sold without exceeding the Maximum Number of Securities; and (iv) fourth, to the extent that the Maximum
Number of Securities has not been reached under the foregoing clauses (i), (ii) and (iii),

pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number
of Securities.


 


2.1.5       Demand
Registration Withdrawal. A majority-in-interest of the Demanding Holders initiating a Demand Registration or a majority-in-interest
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 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, 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.

of the Company (or by the Company and by the stockholders of the Company including, without limitation, pursuant to Section 2.1
hereof), 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 stockholders, (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 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 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

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 shares of Common Stock,
if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights of
other stockholders 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,

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), Common Stock,

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 or Underwriters (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. 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

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”); 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 register 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 $10,000,000.


 


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 the Chairman of the Board 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, 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.

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

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;


 






    	 	8	 



    


    

 


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 or any document that is to be incorporated by reference into 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;


 


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 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 Registrable Securities involving gross proceeds in excess of $50,000,000, 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.


 






    	 	9	 



    


    

 


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.


 


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 shares of Common Stock 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.


 


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 and directors
and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities
and expenses (including attorneys’ fees) caused by 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 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.


 


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 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 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.


 






    	 	10	 



    


    

 


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.

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, but only if such Permitted Transferee agrees
to become bound by the transfer restrictions set forth in this Agreement.


 


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

5.5.       Amendments
and Modifications. Upon the written consent of the Company and the Holders of at least sixty-five percent (65%) of the Registrable
Securities at the time in question, 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 his, her
or its capacity as a holder of the shares of capital stock 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 (i) a Holder of Registrable Securities
and (ii) the Sponsor and its permitted transferees under the Forward Purchase Agreement, has any right to require the Company to
register 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 upon the earlier of (i)  the tenth anniversary of the date of this Agreement or (ii) the
date as of which (A) all of the Registrable Securities have been sold pursuant to a Registration Statement (but in no event
prior to the applicable period referred to in Section 4(a)(3) of the Securities Act and Rule 174 thereunder (or any successor
rule promulgated thereafter by the Commission)) or (B) the Holders of all Registrable Securities are permitted to sell the
Registrable Securities under Rule 144 (or any similar provision) under the Securities Act without limitation on the amount
of securities sold or the manner of sale. The provisions of Section 3.5 and Article IV shall survive
any termination.
