Registration. The Company agrees that, within twenty (20) business days after the consummation of the Business Combination, the Company
will use commercially reasonable efforts to file with the Commission (at the Company’s sole cost and expense) a post-effective
amendment to the Registration Statement on Form S-1 (File No. 333-[●]) previously filed with the Commission or a new
Registration Statement registering the resale or other disposition of the Registrable Securities (a “Shelf Registration”)
pursuant to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission).

 

    

     

    

 

2.1.2        Effective
Registration. The Company shall use commercially reasonable efforts to cause such Registration Statement to become effective. Subject
to the limitations contained in this Agreement, the Company shall effect any Shelf Registration on such appropriate registration form
of the Commission (a) as shall be selected by the Company and (b) as shall permit the resale or other disposition of the Registrable
Securities by the Holders. If at any time a Registration Statement filed with the Commission pursuant to Section 2.1.1 is
effective and a Holder provides written notice to the Company that it intends to effect an offering of all or part of the Registrable
Securities included on such Registration Statement, the Company will use commercially reasonable efforts to amend or supplement such
Registration Statement as may be necessary in order to enable such offering to take place in accordance with the terms of this Agreement.

 

2.1.3        Underwritten
Offering. Subject to the provisions of subsection 2.1.4 and Section 2.3 hereof, any Demanding Holder may
make a written demand for an Underwritten Offering pursuant to a Registration Statement filed with the Commission in accordance with

Offering and the intended method(s) of distribution thereof (an “Underwritten Demand”). The Company shall,
within ten (10) business days of the Company’s receipt of the Underwritten Demand, notify, in writing, all other Holders of
such demand, and each Holder who thereafter requests to include all or a portion of such Holder’s Registrable Securities in such
Underwritten Offering pursuant to such Underwritten Demand (each such Holder that requests to include all or a portion of such Holder’s
Registrable Securities in such Underwritten Offering, a “Requesting Holder”) shall so notify the Company, in
writing, within two (2) days (one (1) day if such offering is an overnight or bought Underwritten Offering) 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),
such Requesting Holder(s) shall be entitled to have their Registrable Securities included in such Underwritten Offering pursuant
to such Underwritten Demand. All such Holders proposing to distribute their Registrable Securities through such Underwritten Offering

Offering and (iii) an Underwritten Offering unless the reasonably expected aggregate gross proceeds from the offering of the Registrable
Securities to be registered in connection with such Underwritten Offering are at least $[●].

 

    

     

    

 

2.1.4        Reduction
of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Offering pursuant to an Underwritten Demand,
in good faith, advise or advises the Company, the Demanding Holders, the Requesting Holders and other persons or entities holding Class A
Common Stock or other equity securities of the Company that the Company is obligated to include pursuant to separate written contractual
arrangements with such persons or entities (if any) in writing that the dollar amount or number of Registrable Securities or other equity
securities of the Company requested to be included in such Underwritten Offering exceeds the maximum dollar amount or maximum number
of equity securities of the Company 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: (a) first, the Registrable Securities of the Demanding Holders (pro rata based on the respective number of
Registrable Securities that each Demanding Holder has requested be included in such Underwritten Offering and the aggregate number of
Registrable Securities that the Demanding Holders have requested be included in such Underwritten Offering (such proportion is referred
to herein as “Pro Rata”)) that 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 the Requesting Holders, Pro Rata, which can be sold without exceeding the Maximum Number of Securities; (c) third,

Company held by other persons or entities that the Company is obligated to include pursuant to separate written contractual arrangements
with such persons or entities and that can be sold without exceeding the Maximum Number of Securities.

 

2.1.5        A
majority-in-interest of the Demanding Holders initiating an Underwritten Demand shall have the right to withdraw from an Underwritten
Offering pursuant to such Underwritten Demand for any or no reason whatsoever upon written notification to the Company and the Underwriter

2.2          Piggyback
Registration.

 

2.2.1        Piggyback
Rights. Subject to the provisions of subsection 2.2.2 and Section 2.3 hereof, if, at any time on or after
the date the Company consummates a Business Combination, the Company proposes to consummate an Underwritten Offering for its own
account or for the account of stockholders of the Company, then the Company shall give written notice of such proposed action to all
of the Holders as soon as practicable, which notice shall (a) describe the amount and type of securities to be included, the intended
method(s) of distribution and the name of the proposed managing Underwriter or Underwriters, if any, and (b) offer to all of
the Holders the opportunity to include such number of Registrable Securities as such Holders may request in writing within  two
(2) days (unless such offering is an overnight or bought Underwritten Offering, then one (1) day), in each case 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 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 Piggyback Registration and to permit the resale or other disposition of such Registrable Securities
in accordance with the intended method(s) of distribution thereof. All such Holders proposing to include Registrable Securities
in 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. Notwithstanding the foregoing, the Company is not obligated
to effect such Underwritten Offering unless the reasonably expected aggregate gross proceeds from the offering of the Registrable Securities
to be registered in connection with such Underwritten Offering are at least $[●].

shares or equity securities of the Company, if any, as to which the Underwritten Offering has been demanded pursuant to separate written
contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (b) the Registrable
Securities as to which a Piggyback Registration has been requested pursuant to Section 2.2 hereof and (c) the shares
or equity securities of the Company, if any, as to which inclusion in the Underwritten Offering has been requested pursuant to separate
written contractual piggyback registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

 

(i)           If

Registration Withdrawal. Any Holder 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 commencement of the Underwritten Offering. 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 Piggyback
Registration at any time prior to the commencement of the Underwritten Offering. 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

on Registration Rights. If (a) the Company has initiated a Registration, delivered
written notice thereof to the Holders prior to receipt of a demand registration pursuant to subsection 2.1.2 and 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 Offering pursuant to an Underwritten Demand and the Company and the Holders are
unable to obtain the commitment of underwriters to firmly underwrite the offer; or (c) the Holders have requested an
Underwritten Offering pursuant to an Underwritten Demand and in the good faith judgment of the Board such Underwritten Offering
would be seriously detrimental to the Company and the Board concludes as a result that it is essential to defer the undertaking of
such Underwritten Offering at such time, then, in the case of (c) 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 to undertake such Underwritten Offering in the near future and that it is therefore essential to defer the undertaking of
such Underwritten Offering and, further, in the case of (a), (b) and (c) the Company shall have the right to defer such
registration or offering, as applicable, 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 twice in any twelve (12)-month period.

 

2.4          Opt-Out
Notices. Any Holder may deliver written notice (an “Opt-Out Notice”)
to the Company requesting that such Holder not receive notice from the Company of any Underwritten Demand, Piggyback Registration, the
withdrawal of any Underwritten Demand or Piggyback Registration or any event that would lead to a Suspension Period as contemplated by
Section 3.4 hereof; provided, however, that such Holder may later revoke any such Opt-Out Notice in writing. Following receipt
of an Opt-Out Notice from a Holder (unless subsequently revoked), the Company shall not deliver any notice to such Holder pursuant to
subsections 2.1.3, 2.2.1 and 3.1.9 and Section 3.4 hereof, as applicable, and such Holder shall
no longer be entitled to the rights associated with any such notice and each time prior to a Holder’s intended use of an effective
Registration Statement, such Holder will notify the Company in writing at least two Business Days in advance of such intended use, and
if a notice of a Suspension Period was previously delivered (or would have been delivered but for the provisions or this Section 2.4)
and the Suspension Period remains in effect, the Company will so notify such Holder, within one Business Day of such Holder’s notification
to the Company, by delivering to such Holder a copy of such previous notice of such Suspension Period, and thereafter will provide such
Holder with the related notice of the conclusion of such Suspension Period immediately upon its availability.

Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions;
provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify or take any action to which it would be subject to general service of process or taxation in any such
jurisdiction where it is not then otherwise so subject;

 

3.1.5        cause
all such Registrable Securities to be listed on each securities exchange or automated quotation system on which similar securities issued

each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any

for such purpose and promptly use commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal
if such stop order should be issued;

 

3.1.8        during
the Effectiveness Period, furnish a conformed copy of each filing of any Registration Statement or Prospectus or any amendment or supplement
to such Registration Statement or Prospectus or any document that is to be incorporated by reference into such Registration Statement
or Prospectus, promptly after such filing of such documents with the Commission to each seller of such Registrable Securities or its
counsel; provided, that the Company will not have any obligation to provide any document pursuant to this clause that is available on
the Commission’s EDGAR system;

 

3.1.9        notify
the Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act,
of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes
a Misstatement, and then to correct such Misstatement as set forth in Section 3.4 hereof;

 

3.1.10      permit
a representative of the Holders, the Underwriters, if any, and any attorney or accountant retained by such Holders or Underwriters to
participate, at each such person’s own expense, in the preparation of the Registration Statement or the Prospectus, 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 comfort letter from the Company’s independent registered public accountants in the event of an Underwritten Offering, in customary
form and covering such matters of the type customarily covered by 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 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 placement
agent, sales agent or Underwriters may reasonably request and as are customarily included in such opinions and negative assurance letters,
and reasonably satisfactory to such placement agent, sales agent or Underwriters;

 

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       use
commercially reasonable efforts to make available senior executives of the Company to participate in customary “road show”
presentations that may be reasonably requested by the Underwriters in any Underwritten Offering;

 

3.1.16       until
the date the Registrable Securities may be sold under Rule 144, in order to permit the Holders to conduct sales (including continuous
offerings based on market prices and block trades) of the Registrable Securities offered pursuant to the Registration Statement (“Brokerage
Trades”) through [two] or more reputable investment banks or other reputable broker-dealers designated by the Company (“Financial
Counterparties”): (a) enter into an equity distribution agreement or sales agreement with the Financial Counterparties,
in customary form, which shall include, among other provisions, indemnities similar to those in Article IV, and representations,
covenants and other indemnities and rights and obligations as are customary in equity distribution agreements for issuer ATM programs
(including an obligation of the Company to reimburse the Financial Counterparties for the expense of one counsel to the Financial Counterparties);
(b) notify the Holders of the identities of the Financial Counterparties; (c) to the extent requested by a Financial Counterparty
in order to engage in Brokerage Trades, the Company shall allow the Financial Counterparties to conduct customary “underwriter’s
due diligence” with respect to the Company, which may be on a periodic “bring down” basis when the Company files periodic
or current reports or there is material news about the Company, including (1) by using commercially reasonable efforts to cause
its independent certified public accountants to provide to the Financial Counterparties a “cold comfort” letter in form and
substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed
to the Financial Counterparties, (2) by using commercially reasonable efforts to cause its outside counsel to the Company to deliver
an opinion in form, scope and substance as is customarily given in an underwritten public offering, including a standard “10b-5”
letter for such offering, addressed to the Financial Counterparties, and (3) by providing a standard officer’s certificate
from the chief executive officer or chief financial officer, or other officers serving such functions, of the Company addressed to the
Financial Counterparties; and (d) shall take such other reasonable action as requested by the Financial Counterparties in order
to expedite or facilitate the Brokerage Trades; and

 

    

     

    

 

3.1.17       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 in respect 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 or entity may participate
in any Underwritten Offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless
such person or entity (a) agrees to sell such person’s or entity’s securities on the basis provided in any underwriting
arrangements approved by the Company and (b) 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 or includes 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 Registration Statement or
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 Registration Statement or Prospectus may be resumed. If the filing, initial effectiveness or continued use of a
Registration Statement in respect of any Registration or Underwritten Offering 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 (any such
period, a “Suspension Period”). In the event the Company exercises its rights under the preceding sentences in
this Section 3.4, the Holders agree to suspend, immediately upon their receipt of the notices referred to in this
Section 3.4, their use of the Registration Statement or Prospectus in connection with any resale or other disposition of
Registrable Securities. The Company shall immediately notify the Holders of the expiration of any Suspension Period.

 

    

     

    

 

3.5          Reporting
Obligations.

 

3.5.1        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 Section 13(a) or 15(d) of the Exchange Act. 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 resell or otherwise dispose of Registrable Securities 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.

 

3.5.2        The
legend on any Registrable Securities covered by this Agreement shall be removed if (i) such Registrable Securities are sold pursuant
to an effective Registration Statement, (ii) a Registration Statement covering the resale of such Registrable Securities is effective
under the Securities Act and the applicable holder of such Registrable Securities and the broker of such holder each delivers to the
Company a representation letter agreeing that such Registrable Securities will be sold under such effective Registration Statement, (iii) if
Registrable Securities may be sold by the Holder thereof free of restrictions pursuant to Rule 144(b) under the Securities
Act or (iv) such Registrable Securities are being sold, assigned or otherwise transferred pursuant to Rule 144 under the Securities
Act; provided, that with respect to clause (iii) or (iv) above, the Holder of such Registrable Securities has provided
all necessary documentation and evidence (which may include an opinion of counsel) as may reasonably be required by the Company to confirm
that the legend may be removed under applicable securities law. The Company shall cooperate with the applicable holder of Registrable
Securities covered by this Agreement to effect removal of the legend on such shares pursuant to this subsection 3.5.2 as soon
as reasonably practicable after delivery of notice from such Holder that the conditions to removal are satisfied (together with any documentation
required to be delivered by such Holder pursuant to the immediately preceding sentence). The Company shall bear all direct costs and
expenses associated with the removal of a legend pursuant to this subsection 3.5.2; provided, that the applicable Holder
shall be responsible for all legal fees and expenses of counsel incurred by such holder with respect to delivering the legal opinion
to the Company.

 

    

     

    

 

Article 4

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) (collectively, the “Holder Indemnified Persons”)
against all losses, claims, damages, liabilities and expenses (including reasonable attorneys’ fees and inclusive of all reasonable
attorneys’ fees arising out of the enforcement of each such persons’ rights under this Section 4.1) resulting
from any Misstatement, except insofar as the same are caused by or contained or included in any information furnished in writing to the
Company by or on behalf of such Holder Indemnified Person specifically for use in the Registration Statement or Prospectus in which the
Misstatement was made.

 

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, severally and not jointly, indemnify the Company, its officers, directors,
employees, advisors, agents, representatives and each person who controls the Company (within the meaning of the Securities Act) against
any losses, claims, damages, liabilities and expenses (including reasonable attorneys’ fees and inclusive of all reasonable attorneys’
fees arising out of the enforcement of each such persons’ rights under this Section 4.1) resulting from any Misstatement,
but only to the extent that the same are made in reliance on and in conformity with information relating to the Holder so furnished in
writing to the Company by or on behalf of such Holder specifically for use in the Registration Statement or Prospectus in which the Misstatement
was made. In no event shall the liability of any selling Holder hereunder be greater in amount than the net proceeds received by such
Holder from the sale of Registrable Securities pursuant to such Registration Statement giving rise to such indemnification obligation.

 

4.1.3        Any
person entitled to indemnification herein shall (a) 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 (b) 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 or
there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying
party, 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 is held by a court of competent jurisdiction to be unavailable to 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 to the extent permitted by law 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 a court of law by reference to, among other things, whether the
Misstatement relates to information supplied by such indemnifying party or such 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.

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

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 each such 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

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF THE BUYER

 

The Buyer represents and warrants that the statements
contained in this Article III are correct and complete as of the date of this Agreement.

 

Section 3.1          Organization and Good Standing.
The Buyer is a limited liability company duly organized, validly existing, and in good standing under the laws of the state of Delaware.

 

Section 3.2          Power and Authority; Enforceability.
This Agreement constitutes the legal, valid, and binding obligation of the Buyer, enforceable against the Buyer in accordance with its
terms. The Buyer has full entity power and authority to execute and deliver this Agreement and to perform its obligations hereunder.
The Buyer has taken all actions necessary to authorize the execution and delivery of this Agreement, the performance of its obligations
hereunder and the consummation of the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered
by, and is enforceable against, the Buyer.

 

Section 3.3          Investment Representations.

 

(a)       The
Buyer is an “accredited investor” as defined in Rule 501 of Regulation D under the Securities Act.

 

(b)       The
Buyer has received, has thoroughly read, is familiar with and understands the contents of this Agreement.

 

(c)       The
Buyer hereby acknowledges that an investment in the Shares involves certain significant risks. The Buyer acknowledges that there is a
substantial risk that it will lose all or a portion of its investment and that it is financially capable of bearing the risk of such investment
for an indefinite period of time. The Buyer has no need for liquidity in its investment in the Shares for the foreseeable future and is
able to bear the risk of that investment for an indefinite period. The Buyer understands that there presently is no public market for
the Shares and none is anticipated to develop in the foreseeable future. The Buyer’s present financial condition is such that the
Buyer is under no present or contemplated future need to dispose of any portion of the Shares subscribed for hereby to satisfy any existing
or contemplated undertaking, need or indebtedness. The Buyer’s overall commitment to investments which are not readily marketable
is not disproportionate to its net worth and the investment in the Company will not cause such overall commitment to become excessive.

 

(d)       The
Buyer acknowledges that the Shares have not been and will not be registered under the Securities Act, or any state securities act, and
are being sold on the basis of exemptions from registration under the Securities Act and applicable state securities acts, except those
state securities acts that require registration of the Shares thereunder. Reliance on such exemptions, where applicable, is predicated
in part on the accuracy of the Buyer’s representations and warranties set forth herein. The Buyer acknowledges and hereby agrees
that the Shares will not be transferable under any circumstances unless the Buyer either registers the Shares in accordance with federal
and state securities laws or finds and complies with an available exemption under such laws. Accordingly, the Buyer hereby acknowledges
that there can be no assurance that it will be able to liquidate its investment in the Company.

 

(e)       There
are substantial risk factors pertaining to an investment in the Company. The Buyer acknowledges that it has read the information set forth
above regarding certain of such risks and is familiar with the nature and scope of all such risks, including, without limitation, risks
arising from the fact that the Company is an entity with limited operating history and financial resources; and the Buyer is fully able
to bear the economic risks of such investment for an indefinite period, and can afford a complete loss thereof.

 

    3

     

    

 

(f)       The
Buyer has been given the opportunity to (i) ask questions of and receive answers from the Company and its designated representatives concerning
the terms and conditions of the offering, the Company and the business and financial condition of the Company and (ii) obtain any additional
information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to assist the Buyer in
evaluating the advisability of the purchase of the Shares and an investment in the Company. The Buyer further represents and warrants
that, prior to signing this Agreement, it has asked such questions, received such answers and obtained such information as it has deemed
necessary or advisable to evaluate the merits and risks of the purchase of the Shares and an investment in the Company. The Buyer is not
relying on any oral representation made by any person as to the Company or its operations, financial condition or prospects.

 

(g)       The
Buyer understands that no federal, state or other governmental authority has made any recommendation, findings or determination relating
to the merits of an investment in the Company.

TO ANY AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING HERETO.
IN THE EVENT OF AN ACTION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO TRIAL BY A COURT.

 

Section 5.5          Counterparts. This Agreement
may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and
the same instrument.

 

Section 5.6          Headings. The article and
section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation
of this Agreement.

 

Section 5.7          Governing Law. This Agreement,
the entire relationship of the parties hereto, and any litigation between the parties (whether grounded in contract, tort, statute, law
or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the State of Delaware, without
giving effect to its choice of laws principles.

 

Section 5.8          Amendments. This Agreement
may not be amended, modified or waived as to any particular provision, except by a written instrument executed by the parties hereto.

 

Section 5.9          Severability. The provisions
of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability
of the other provisions hereof; provided that if any provision of this Agreement, as applied to any party hereto or to any circumstance,
is adjudged by a Governmental Body, arbitrator, or mediator not to be enforceable in accordance with its terms, the parties hereto agree
that the Governmental Body, arbitrator, or mediator making such determination will have the power to modify the provision in a manner

    5

     

    

 

Section 5.11          Construction. The
parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or
interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of
proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. Any
reference to any federal, state, local, or foreign Law will be deemed also to refer to Law as amended and all rules and regulations
promulgated thereunder, unless the context requires otherwise. The words “include,”
 “includes,” and “including” will be deemed to be followed by “without
limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words
in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words
 “this Agreement,” “herein,” “hereof,” “hereby,”
 “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision
unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have
independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any
respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of
the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such
party hereto is in breach of the first representation, warranty, or covenant.

 

Section 5.12          Waiver. No waiver by any party
hereto of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend
to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising
because of any prior or subsequent occurrence.
