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 Business Combination, the Holders of at least a majority in interest of the then-outstanding number of Registrable Securities
(the “Demanding Holders”) may make a written demand for Registration under the Securities Act of all or part of their
Registrable Securities, which written demand shall describe the amount and type of securities to be included in such Registration and
the intended method(s) of distribution thereof (such written demand a “Demand Registration”). The Company shall, within
ten (10) days of the Company’s receipt of the Demand Registration, notify, in writing, all other Holders of Registrable Securities
of such demand, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable
Securities in a Registration pursuant to a Demand Registration (each such Holder that includes all or a portion of such Holder’s
Registrable Securities in such Registration, a “Requesting Holder”) shall so notify the Company, in writing, within
five (5) days after the receipt by the Holder of the notice from the Company. Upon receipt by the Company of any such written notification
from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable Securities included
in a Registration pursuant to a Demand Registration and the Company shall effect, as soon thereafter as 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. 


 






    5


     


    

 


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.


  


2.1.4 Reduction of Underwritten
Offering. If the managing Underwriter or Underwriters in an Underwritten Registration pursuant to a Demand Registration, in good faith,
advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable
Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other Class A Common
Stock or other equity securities that the Company desires to sell and the Class A Common Stock, if any, as to which a Registration has
been requested pursuant to separate written contractual piggy-back registration rights held by any other stockholders who desire to sell,
exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely
affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum
dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company
shall include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting
Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if
any) has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Demanding
Holders and Requesting Holders have requested be included in such Underwritten Registration (such proportion is referred to herein as
“Pro Rata”)) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the
Maximum Number of Securities has not been reached under the foregoing clause (i), Class A Common Stock 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), Class A Common Stock 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. A majority-in-interest of the Demanding Holders initiating a Demand Registration or a majority-in-interest of the Requesting
Holders (if any), pursuant to a Registration under subsection 2.1.1 shall have the right to withdraw from a Registration pursuant to such
Demand Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any)
of their intention to withdraw from such Registration prior to the effectiveness of the Registration Statement filed with the Commission
with respect to the Registration of their Registrable Securities pursuant to such Demand Registration. Notwithstanding anything to the
contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Registration
pursuant to a Demand Registration prior to its withdrawal under this subsection 2.1.5. 


 


2.2 Piggyback Registration.


 


2.2.1 Piggyback Rights. If,
at any time on or after the date the Company consummates an initial 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 stockholders of the Company (or by
the Company and by the stockholders of the Company including, without limitation, pursuant to Section 2.1 hereof), other than a Registration
Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities
solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company
or (iv) for a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of
Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration
Statement, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of
distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the
Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request
in writing within five (5) days after receipt of such written notice (such Registration a “Piggyback Registration”). The Company
shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use its commercially reasonable
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 in writing that the dollar
amount or number of shares of Class A Common Stock that the Company desires to sell, taken together with (i) the shares of Class A Common
Stock, 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 shares of Class A Common Stock, if any, as to which Registration has been requested pursuant
to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities,
then:


 


(a) If the Registration is
undertaken for the Company’s account, the Company shall include in any such Registration (A) first, the Class A Common Stock 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 exercising its rights to register its Registrable Securities, 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 Class A Common Stock, if any, as to which Registration has been requested
pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding
the Maximum Number of Securities;


  






    7


     


    

 


(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 Class A Common Stock 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 Class A Common Stock 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 Class A Common Stock 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.


  






    8


     


    

 


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 file a Registration Statement relating to all or such portion
of such Holder’s Registrable Securities as are specified in such written request, together with all or such portion of Registrable
Securities of any other Holder or Holders joining in such request as are specified in the written notification given by such Holder or
Holders; provided, however, that the Company shall not be obligated to effect any such Registration pursuant to Section 2.3 hereof if
(i) a Form S-3 is not available for such offering; or (ii) the Holders of Registrable Securities, together with the Holders of any other
equity securities of the Company entitled to inclusion in such Registration, propose to sell the Registrable Securities and such other
equity securities (if any) at any aggregate price to the public of less than $10,000,000.


 


2.4 Restrictions on Registration
Rights. If (A) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of
the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and
provided that the Company has delivered written notice to the Holders prior to receipt of a Demand Registration pursuant to subsection
2.1.1 and it continues to actively employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become
effective; (B) the Holders have requested an Underwritten Registration and the Company and the Holders are unable to obtain the commitment
of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the Board such Registration would be seriously detrimental
to the Company and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time,
then in each case the Company shall furnish to such Holders a certificate signed by the Chairman of the Board stating that in the good
faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future
and that it is therefore essential to defer the filing of such Registration Statement. In such event, the Company shall have the right
to defer such filing for a period of not more than thirty (30) days; provided, however, that the Company shall not defer its obligation
in this manner more than once in any 12 month period.

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

by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that such representative
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

law;

and reasonably satisfactory to a majority in interest of the participating Holders;


 






    11

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 $51,000,000, 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

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 ninety (90) days in any 12-month period, 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.


  






    12


     


    

 


3.5 Reporting Obligations.
As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange
Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required
to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders
with true and complete copies of all such filings. The Company further covenants that it shall take such further action as any Holder
may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of the Class A Common Stock
held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated
under the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon
the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether
it has complied with such requirements.





 


ARTICLE IV


INDEMNIFICATION AND CONTRIBUTION


 


4.1 Indemnification.


 


4.1.1 The Company agrees to
indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and each person who controls
such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’
fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary
Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information
furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers
and directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided
in the foregoing with respect to the indemnification of the Holder.


 


4.1.2 In connection with any
Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing
such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus
and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the
Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation
reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus
or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein
or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained
in any information or affidavit so furnished in writing by such Holder expressly for use therein. 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. For the avoidance of doubt,
the obligation to indemnify under this Section 4.1.2 shall be several, not joint and several, among the Holders of Registrable Securities,
and the total indemnification liability of a Holder under this Section 4.1.2 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.


  






    13


     


    

 


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.


 


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.

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

of the assignee, in a form reasonably satisfactory to the Company, to be bound by the terms and provisions of this Agreement (which may
be accomplished by an addendum or certificate of joinder to this Agreement). Any transfer or assignment made other than as provided in
this Section 5.2 shall be null and void.

5.3 Counterparts. This Agreement

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 capital stock of the Company,
in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected.
No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the
Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or
the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude
the exercise of any other rights or remedies hereunder or thereunder by such party.


 


5.6 Other Registration Rights.
The Company represents and warrants that no person, other than 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

of all Registrable Securities are permitted to sell the Registrable Securities under Rule 144 (or any similar provision) under the Securities
Act without limitation on the amount of securities sold or the manner of sale and without compliance with the current public reporting
requirements set forth under Rule 144(i)(2). The provisions of Section 3.5 and Article IV shall survive any termination.
