2. REGISTRATION
RIGHTS.


 


2.1 Demand Registration.


 


2.1.1 Request
for Registration. At any time and from time to time on or after (i) the date that the Company consummates a Business Combination
with respect to the Private Units (or underlying shares of Common Stock), Over-Allotment Units (or underlying shares of Common
Stock) and Loan Securities or (ii) three months prior to the Release Date with respect to all other Registrable Securities, the
holders of a majority-in-interest of the Registrable Securities, as the case may be, held by the Investors, officers or directors
of the Company or their affiliates, or the transferees of the Investors, may make a written demand, on no more than two occasions,
for registration under the Securities Act of all or part of their Registrable Securities, as the case may be (a “Demand
Registration” ). Any demand for a Demand Registration shall specify the number of shares of Registrable Securities
proposed to be sold and the intended method(s) of distribution thereof. The Company will notify all holders of Registrable Securities
of the demand, and each holder of Registrable Securities who wishes to include all or a portion of such holder’s Registrable Securities
in the Demand Registration (each such holder including shares of Registrable Securities in such registration, a “Demanding
Holder”) shall so notify the Company within fifteen (15) days after the receipt by the holder of the notice from the
Company. Upon any such request, the Demanding Holders shall be entitled to have their Registrable Securities included in the Demand
Registration, subject to Section 2.1.4 and the provisos set forth in Section 3.1.1. The Company shall not be obligated to effect
more than an aggregate of two (2) Demand Registration under this Section 2.1.1 in respect of all Registrable Securities.


 


2.1.2 Effective
Registration. A registration will not count as a Demand Registration until the Registration Statement filed with the Commission
with respect to such Demand Registration has been declared effective and the Company has complied with all of its obligations under
this Agreement with respect thereto; provided, however, that if, after such Registration Statement has been declared effective,
the offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop order or injunction of
the Commission or any other governmental agency or court, the Registration Statement with respect to such Demand Registration will
be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise
terminated, and (ii) a majority-in-interest of the Demanding Holders thereafter elect to continue the offering; provided, further,
that the Company shall not be obligated to file a second Registration Statement until a Registration Statement that has been filed
is counted as a Demand Registration or is terminated.


 


2.1.3 Underwritten
Offering. If a majority-in-interest of the Demanding Holders so elect and such holders so advise the Company as part of their
written demand for a Demand Registration, the offering of such Registrable Securities pursuant to such Demand Registration shall
be in the form of an underwritten offering. In such event, the right of any holder to include its Registrable Securities in such
registration shall be conditioned upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable
Securities in the underwriting to the extent provided herein. All Demanding Holders proposing to distribute their Registrable Securities
through such underwriting shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected
for such underwriting by a majority-in-interest of the holders initiating the Demand Registration.


 


2.1.4 Reduction
of Offering. If the managing Underwriter or Underwriters for a Demand Registration that is to be an underwritten offering advises
the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the
Demanding Holders desire to sell, taken together with all other shares of Common Stock or other securities which the Company desires
to sell and the shares of Common Stock, if any, as to which registration has been requested pursuant to written contractual piggy-back
registration rights held by other stockholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum
number of shares that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution
method, or the probability of success of such offering (such maximum dollar amount or maximum number of shares, as applicable,
the “Maximum Number of Shares” ), then the Company shall include in such registration: (i) first, the Registrable
Securities as to which Demand Registration has been requested by the Demanding Holders (pro rata in accordance with the number
of shares that each such Person has requested be included in such registration, regardless of the number of shares held by each
such Person (such proportion is referred to herein as “Pro Rata” )) that can be sold without exceeding
the Maximum Number of Shares; (ii) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing
clause (i), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding
the Maximum Number of Shares; and (iii) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing
clauses (i) and (ii), the shares of Common Stock or other securities for the account of other persons that the Company is obligated
to register pursuant to written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number
of Shares.


 






    	 



    	 



    

 


2.1.5 Withdrawal.
If a majority-in-interest of the Demanding Holders disapprove of the terms of any underwriting or are not entitled to include all
of their Registrable Securities in any offering, such majority-in-interest of the Demanding Holders may elect to withdraw from
such offering by giving written notice to the Company and the Underwriter or Underwriters of their request to withdraw prior to
the effectiveness of the Registration Statement filed with the Commission with respect to such Demand Registration. If the majority-in-interest
of the Demanding Holders withdraws from a proposed offering relating to a Demand Registration, then such registration shall not
count as a Demand Registration provided for in Section 2.1.


 


2.2 Piggy-Back
Registration.


 


2.2.1 Piggy-Back
Rights. If at any time on or after the date the Company consummates a Business Combination the Company proposes to file a Registration
Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable
or exchangeable for, or convertible into, equity securities, by the Company for its own account or for stockholders of the Company
for their account (or by the Company and by stockholders of the Company including, without limitation, pursuant to Section 2.1),
other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange
offer or offering of securities solely to the Company’s existing 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 (x) give written notice
of such proposed filing to the holders of Registrable Securities as soon as practicable but [in no event less than ten (10) days]
before the anticipated filing date, which notice shall describe the amount and type of securities to be included in such offering,
the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, of the offering,
and (y) offer to the holders of Registrable Securities in such notice the opportunity to register the sale of such number of shares
of Registrable Securities as such holders may request [in writing within five (5) days] following receipt of such notice (a “Piggy-Back
Registration” ). Subject to Section 2.2.2, the Company shall cause such Registrable Securities to be included in such
registration and shall use its reasonable best efforts to cause the managing Underwriter or Underwriters of a proposed underwritten
offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms and conditions
as any similar securities of the Company and to permit the sale or other disposition of such Registrable Securities in accordance
with the intended method(s) of distribution thereof. All holders of Registrable Securities proposing to distribute their securities
through a Piggy-Back Registration that involves an Underwriter or Underwriters shall enter into an underwriting agreement in customary
form with the Underwriter or Underwriters selected for such Piggy-Back Registration. Notwithstanding the provisions set forth in
the immediately preceding sentences, the right to a Piggy-Back Registration set forth under this Section 2.2.1 with respect to
the Registrable Securities shall terminate on the seventh anniversary of the Effective Date.


 


2.2.2 Reduction
of Offering. If the managing Underwriter or Underwriters for a Piggy-Back Registration that is to be an underwritten offering
advises the Company and the holders of Registrable Securities in writing that the dollar amount or number of shares of Common Stock
which the Company desires to sell, taken together with the shares of Common Stock, if any, as to which registration has been demanded
pursuant to written contractual arrangements with persons other than the holders of Registrable Securities hereunder, the Registrable
Securities as to which registration has been requested under this Section 2.2, and the shares of Common Stock, if any, as to which
registration has been requested pursuant to the written contractual piggy-back registration rights of other stockholders of the
Company, exceeds the Maximum Number of Shares, then the Company shall include in any such registration:


 


a) If
the registration is undertaken for the Company’s account: (A) first, the shares of Common Stock or other securities that the Company
desires to sell that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number
of Shares has not been reached under the foregoing clause (A), the shares of Common Stock or other securities, if any, comprised
of Registrable Securities, as to which registration has been requested pursuant to the applicable written contractual piggy-back
registration rights of such security holders, Pro Rata, that can be sold without exceeding the Maximum Number of Shares; and (C)
third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), the shares
of Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written
contractual piggy-back registration rights with such persons and that can be sold without exceeding the Maximum Number of Shares;


 



    	 



    	 



    

 





b) If
the registration is a “demand” registration undertaken at the demand of persons other than either the holders of Registrable
Securities, (A) first, the shares of Common Stock or other securities for the account of the demanding persons that can be sold
without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached
under the foregoing clause (A), the shares of Common Stock or other securities that the Company desires to sell that can be sold
without exceeding the Maximum Number of Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached
under the foregoing clauses (A) and (B), collectively the shares of Common Stock or other securities comprised of Registrable Securities,
Pro Rata, as to which registration has been requested pursuant to the terms hereof, that can be sold without exceeding the Maximum
Number of Shares; and (D) fourth, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses
(A), (B) and (C), the shares of Common Stock or other securities for the account of other persons that the Company is obligated
to register pursuant to written contractual arrangements with such persons, that can be sold without exceeding the Maximum Number
of Shares.


 


2.2.3 Withdrawal.
Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable Securities in any
Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness of the Registration
Statement. The Company (whether on its own determination or as the result of a withdrawal by persons making a demand pursuant to
written contractual obligations) may withdraw a Registration Statement at any time prior to the effectiveness of such Registration
Statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the holders of Registrable Securities
in connection with such Piggy-Back Registration as provided in Section 3.3.


 


2.2.4 Registrations
on Form S-3 . The holders of Registrable Securities may at any time and from time to time, request in writing that the
Company register the resale of any or all of such Registrable Securities on Form S-3 or any similar short-form registration which
may be available at such time (“Form S-3”); provided, however, that (i) the Company shall not be obligated
to effect such request through an underwritten offering and (ii) the Company shall not be obligated to effect more than two such
requests. Upon receipt of such written request, the Company will promptly give written notice of the proposed registration to all
other holders of Registrable Securities, and, as soon as practicable thereafter, effect the registration of all or such portion
of such holder’s or holders’ Registrable Securities as are specified in such request, together with all or such portion of the
Registrable Securities or other securities of the Company, if any, of any other holder or holders joining in such request as are
specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided,
however, that the Company shall not be obligated to effect any such registration pursuant to this Section 2.2.4: (i) if Form S-3
is not available for such offering; or (ii) if the holders of the Registrable Securities, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities
(if any) at any aggregate price to the public of less than $500,000. Registrations effected pursuant to this Section 2.2,4 shall
not be counted as Demand Registrations effected pursuant to Section 2.1.

of the Board of Directors of the Company, it would be materially detrimental to the Company and its stockholders for such Registration
Statement to be effected at such time; provided further, however, that the Company shall not have the right to exercise the right
set forth in this provision more than once in any 365-day period in respect of a Demand Registration hereunder.

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

may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be

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

the Company, pursuant to a written insider trading compliance program adopted by the Company’s Board of Directors, of the ability
of all “insiders” covered by such program to transact in the Company’s securities because of the existence of material
non-public information, each holder of Registrable Securities included in any registration shall immediately discontinue disposition
of such Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such holder receives

omission (or alleged omission) to state a material fact required to be stated therein or necessary to make the statements therein
not misleading, or any violation by the Company of the Securities Act or any rule or regulation promulgated thereunder applicable
to the Company and relating to action or inaction required of the Company in connection with any such registration; and the Company
shall promptly reimburse the Investor Indemnified Party for any legal and any other expenses reasonably incurred by such Investor
Indemnified Party in connection with investigating and defending any such expense, loss, judgment, claim, damage, liability or
action; provided, however, that the Company will not be liable in any such case to the extent that any such expense, loss, claim,
damage or liability arises out of or is based upon any untrue statement or allegedly untrue statement or omission or alleged omission
made in such Registration Statement, preliminary prospectus, final prospectus, or summary prospectus, or any such amendment or
supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by such selling holder expressly
for use therein. The Company also shall indemnify any Underwriter of the Registrable Securities, their officers, affiliates, directors,
partners, members and agents and each person who controls such Underwriter on substantially the same basis as that of the indemnification
provided above in this Section 4.1.


 






    	 



    	 



    

 


4.2 Indemnification
by Holders of Registrable Securities. Each selling holder of Registrable Securities will, in the event that any registration
is being effected under the Securities Act pursuant to this Agreement of any Registrable Securities held by such selling holder,
indemnify and hold harmless the Company, each of its directors and officers and each Underwriter (if any), and each other selling
holder and each other person, if any, who controls another selling holder or such Underwriter within the meaning of the Securities
Act, against any losses, claims, judgments, damages or liabilities, whether joint or several, insofar as such losses, claims, judgments,
damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or allegedly untrue
statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered
under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement,
or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or the alleged omission
to state a material fact required to be stated therein or necessary to make the statement therein not misleading, if the statement
or omission was made in reliance upon and in conformity with information furnished in writing to the Company by such selling holder
expressly for use therein, and shall reimburse the Company, its directors and officers, and each other selling holder or controlling
person for any legal or other expenses reasonably incurred by any of them in connection with investigation or defending any such
loss, claim, damage, liability or action. Each selling holder’s indemnification obligations hereunder shall be several and not
joint and shall be limited to the amount of any net proceeds actually received by such selling holder.


 


4.3 Conduct of
Indemnification Proceedings. Promptly after receipt by any person of any notice of any loss, claim, damage or liability or
any action in respect of which indemnity may be sought pursuant to Section 4.1 or 4.2, such person (the “Indemnified Party”)
shall, if a claim in respect thereof is to be made against any other person for indemnification hereunder, notify such other person
(the “Indemnifying Party” ) in writing of the loss, claim, judgment, damage, liability or action; provided,
however, that the failure by the Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying Party from
any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying
Party is actually prejudiced by such failure. If the Indemnified Party is seeking indemnification with respect to any claim or
action brought against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action,
and, to the extent that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel
satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume
control of the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal
or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs
of investigation; provided, however, that in any action in which both the Indemnified Party and the Indemnifying Party are named
as defendants, the Indemnified Party shall have the right to employ separate counsel (but no more than one such separate counsel)
to represent the Indemnified Party and its controlling persons who may be subject to liability arising out of any claim in respect
of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the fees and expenses of such counsel
to be paid by such Indemnifying Party if, based upon the written opinion of counsel of such Indemnified Party, representation of
both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. No Indemnifying
Party shall, without the prior written consent of the Indemnified Party, consent to entry of judgment or effect any settlement
of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnity
could have been sought hereunder by such Indemnified Party, unless such judgment or settlement includes an unconditional release
of such Indemnified Party from all liability arising out of such claim or proceeding.


 






    	 



    	 



    

 


4.4 Contribution.


 


4.4.1 If the indemnification
provided for in the foregoing Sections 4.1, 4.2 and 4.3 is unavailable to any Indemnified Party in respect of any loss, claim,
damage, liability or action referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party,
shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage, liability or
action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties
in connection with the actions or omissions which resulted in such loss, claim, damage, liability or action, as well as any other
relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying Party shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by such Indemnified Party or such Indemnifying Party and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.


 


4.4.2 The parties
hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.4 were determined by pro rata allocation
or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately
preceding Section 4.4.1.


 


4.4.3 The amount paid
or payable by an Indemnified Party as a result of any loss, claim, damage, liability or action referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such
Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this
Section 4.4, no holder of Registrable Securities shall be required to contribute any amount in excess of the dollar amount of the
net proceeds (after payment of any underwriting fees, discounts, commissions or taxes) actually received by such holder from the
sale of Registrable Securities which gave rise to such contribution obligation. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty
of such fraudulent misrepresentation.


 


5. RULE 144.


 


5.1 Rule 144.
The Company covenants that it shall file any reports required to be filed by it under the Securities Act and the Exchange Act and
shall take such further action as the holders of Registrable Securities may reasonably request, all to the extent required from
time to time to enable such holders to sell Registrable Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144 under the Securities Act, as such Rules may be amended from time to time, or any similar
rule or regulation hereafter adopted by the Commission.


 


6. MISCELLANEOUS.


 


6.1 Other Registration
Rights. The Company represents and warrants that, except as disclosed in the Company’s registration statement on Form S-1 (File
No. 333-[*]), no person, other than the holders of the Registrable Securities, has any right to require the Company to register
any of the Company’s share capital for sale or to include the Company’s share capital in any registration filed by the Company
for the sale of share capital for its own account or for the account of any other person.


 


6.2 Assignment;
No Third Party Beneficiaries. 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. This Agreement and the rights, duties and obligations of the holders of Registrable
Securities hereunder may be freely assigned or delegated by such holder of Registrable Securities in conjunction with and to the
extent of any transfer of Registrable Securities by any such holder. This Agreement and the provisions hereof shall be binding
upon and shall inure to the benefit of each of the parties, to the permitted assigns of the Investors or holder of Registrable
Securities or of any assignee of the Investors or holder of Registrable Securities. This Agreement is not intended to confer any
rights or benefits on any persons that are not party hereto other than as expressly set forth in Article 4 and this Section 6.2.

personally served, delivered by reputable air courier service with charges prepaid, or transmitted by hand delivery, telegram,

refers to this Agreement. Waivers may be made in advance or after the right waived has arisen or the breach or default waived has
occurred. Any waiver may be conditional. No waiver of any breach of any agreement or provision herein contained shall be deemed
a waiver of any preceding or succeeding breach thereof nor of any other agreement or provision herein contained. No waiver or extension
of time for performance of any obligations or acts shall be deemed a waiver or extension of the time for performance of any other
obligations or acts.


 


6.10 Remedies

under this Agreement, the Investor or any other holder of Registrable Securities may proceed to protect and enforce its rights
by suit in equity or action at law, whether for specific performance of any term contained in this Agreement or for an injunction
against the breach of any such term or in aid of the exercise of any power granted in this Agreement or to enforce any other legal
or equitable right, or to take any one or more of such actions, without being required to post a bond. None of the rights, powers
or remedies conferred under this Agreement shall be mutually exclusive, and each such right, power or remedy shall be cumulative
and in addition to any other right, power or remedy, whether conferred by this Agreement or now or hereafter available at law,
in equity, by statute or otherwise.

Trial by Jury. Each party hereby irrevocably and unconditionally waives the right to a trial by jury in any action, suit, counterclaim
or other proceeding (whether based on contract, tort or otherwise) arising out of, connected with or relating to this Agreement,
the transactions contemplated hereby, or the actions of the Investor in the negotiation, administration, performance or enforcement
