Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, at any time and from time to time on or after the date
the Company consummates the Business Combination, the Holders of at least fifteen percent (15%) of the then-outstanding number of Registrable
Securities (the “Demanding Holders”) may make a written demand for Registration 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 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; and 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.

or other equity securities that the Company desires to sell and the Ordinary Shares, if any, as to which a Registration has been requested
pursuant to separate written contractual piggy-back registration rights held by any other shareholders who desire to sell, exceeds the
maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting
the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar
amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company
shall include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting
Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if

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

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

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 furnish
a copy thereof to each seller of such Registrable Securities and its counsel, including, without limitation, providing copies promptly
upon receipt of any comment letters received with respect to any such Registration Statement or Prospectus;


 


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 (such representative to be selected by a majority of the participating 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; and provided further, the Company may not include the name
of any Holder or Underwriter or any information regarding any Holder or Underwriter in any Registration Statement or Prospectus, any amendment
or supplement to such Registration Statement or Prospectus, any document that is to be incorporated by reference into such Registration
Statement or Prospectus, or any response to any comment letter, without the prior written consent of such Holder or Underwriter and providing
each such Holder or Underwriter a reasonable amount of time to review and comment on such applicable document, which comments the Company
shall include unless contrary to applicable law;


 


3.1.11 obtain a “cold
comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten Registration
which the participating Holders may rely on, 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);


 






    8 


     


    

 


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


 


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


 


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


 


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


 


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


 


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.


 


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.


 






    9 


     


    

 


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.


 


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 (plus local 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.

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

Holder’s rights, duties or obligations under this Agreement, in whole or in part, except in connection with a transfer of Registrable

5.5 Amendments and Modifications.
Upon the written consent of the Company and the Holders of at least a majority in interest 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 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 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.

by the Commission)) or (B) the Holders of all Registrable Securities are permitted to sell the Registrable Securities without registration
pursuant to Rule 144 (or any similar provision) under the Securities Act with no volume or other restrictions or limitations. The
provisions of Section 3.5 and Article IV shall survive any termination.
