2.1.1
Request for Registration. Subject to the provisions of subsection ‎2.1.4 and Section ‎2.4 hereof, at
any time and from time to time on or after the date the Company consummates the initial Business Combination, the Sponsor 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 (i) file a Registration
Statement in respect of all Registrable Securities requested by the Sponsor and Requesting Holder(s) pursuant such Demand Registration,
not more than forty five (45) days immediately after the Company’s receipt of the Demand Registration, and (ii) shall effect the
registration thereof as soon as practicable thereafter. 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) the Sponsor thereafter
affirmatively elects 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 the Sponsor so advises the Company as part of its 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 the Sponsor 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 Sponsor.


 


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 Sponsor and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable
Securities that the Sponsor and the Requesting Holders (if any) desire to sell, taken together with all other Ordinary Shares or other
equity securities that the Company desires to sell and the Ordinary Shares, if any, as to which a Registration has been requested pursuant
to separate written contractual piggy-back registration rights held by any other shareholders who desire to sell, exceeds the maximum
dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed
offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum
number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include
in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Sponsor and the Requesting Holders (if any) (pro
rata based on the respective number of Registrable Securities that each Sponsor and Requesting Holder (if any) has requested be included
in such Underwritten Registration and the aggregate number of Registrable Securities that the Sponsor and Requesting Holders have requested
be included in such Underwritten Registration) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the
extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Ordinary Shares or other equity
securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (iii) third, to
the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the Ordinary Shares or
other equity securities of other persons or entities that the Company is obligated to register in a Registration 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. The Sponsor 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

2.2 Piggyback
Registration.


 


2.2.1 Piggyback
Rights. If, at any time on or after the date the Company consummates a Business Combination, the Company proposes to file a Registration
Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or
exchangeable for, or convertible into equity securities, for its own account or for the account of shareholders of the Company (or by
the Company and by the shareholders of the Company including, without limitation, pursuant to Section ‎2.1 hereof),
other than a Registration Statement (i) filed in connection with any employee share option or other benefit plan, (ii) for an exchange
offer or offering of securities solely to the Company’s existing shareholders, (iii) for an offering of debt that is convertible
into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall give written notice of such proposed
filing to all of the Holders of Registrable Securities as soon as 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
enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Company.


 


2.2.2 Reduction
of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Registration that is to be a Piggyback
Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration

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


 


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


 


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

2.2.3 Piggyback
Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration for
any or no reason whatsoever upon written notification to the Company and the Underwriter 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
Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to Section ‎2.2 hereof
shall not be counted as a Registration pursuant to a Demand Registration effected under Section ‎2.1 hereof.


 


2.3 Registrations
on Form S-3. The Holders of Registrable Securities may at any time, and from time to time, request in writing that the Company, pursuant
to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission), register the resale of any or
all of their Registrable Securities on Form S-3 or any similar short-form registration statement that may be available at such time (“Form
S-3”); 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
$1,000,000.


 


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

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 $10,000,000, 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.


 


3.6 Requirements
for Participation in Underwritten Offerings and Limitations on Registration Rights. 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.

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
agents 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.


 






    10


     


    

 


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 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.

bound by the transfer restrictions set forth in this Agreement and other applicable agreements.

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.

Company unless and until the Company shall have received (i) written notice of such assignment as provided in Section ‎5.1 hereof

5.3 Counterparts.

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 (I) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK AS APPLIED TO AGREEMENTS AMONG NEW
YORK RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN NEW YORK AND (II) THE VENUE FOR ANY ACTION TAKEN WITH RESPECT TO THE

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 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

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

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.
