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

thereafter as practicable, but not more than forty-five (45) days immediately after the Company’s receipt of the Demand Registration,

Registration under this subsection 2.1.1 with respect to any or all Registrable Securities; provided, however,

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.


 






    4 


     


    

 


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.

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.

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 shares of Common Stock or
other equity securities that the Company desires to sell and the shares of 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), the Registrable
Securities of Holders (Pro Rata, based on the respective number of Registrable Securities that each Holder has so requested) exercising

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 shares of Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding
the Maximum Number of Securities; and (iv) fourth, to the extent that the Maximum Number of Securities has not been reached under the
foregoing clauses (i), (ii) and (iii), the shares of Common Stock or other equity securities of other persons or entities that the Company

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

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
(or in the case of an Underwritten Registration pursuant to Rule 415 under the Securities Act, at least two business days prior to the
time of pricing of the applicable 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 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

Registration prior to its withdrawal under this subsection 2.2.3.


  


2.2.4 Unlimited Piggyback Registration

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

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

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 twelve (12)-month period.

be listed on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed;


 


3.1.6 provide a transfer agent or warrant agent,
as applicable, and registrar for all such Registrable Securities no later than the effective date of such Registration Statement;


 


3.1.7 advise each seller of such Registrable
Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending
the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and promptly use
its reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;


 


3.1.8 at least five (5) days prior to the filing
of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus or any document
that is to be incorporated by reference into such Registration Statement or Prospectus, furnish a copy thereof to each seller of such
Registrable Securities and its counsel, including, without limitation, providing copies promptly upon receipt of any comment letters received
with respect to any such Registration Statement or Prospectus;


 


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


 


3.1.10 permit a representative of the Holders
(such representative to be selected by a majority of the participating Holders), the Underwriters, if any, and any attorney or accountant
retained by such Holders, or Underwriter to participate, at each such person’s own expense, in the preparation of the Registration
Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such
representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that
such representatives, or Underwriters enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company,
prior to the release or disclosure of any such information; and provided further, the Company may not include
the name of any Holder or Underwriter or any information regarding any Holder or Underwriter in any Registration Statement or Prospectus,
any amendment or supplement to such Registration Statement or Prospectus, any document that is to be incorporated by reference into such
Registration Statement or Prospectus, or any response to any comment letter, without the prior written consent of such Holder or Underwriter
and providing each such Holder or Underwriter a reasonable amount of time to review and comment on such applicable document, which comments
the Company shall include unless contrary to applicable law;


 


3.1.11 obtain a “cold comfort” letter
from the Company’s independent registered public accountants in the event of an Underwritten Registration which the participating
Holders may rely on, in customary form and covering such matters of the type customarily covered by “cold comfort” letters
as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders;


 


3.1.12 on the date the Registrable Securities
are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel representing the Company for the
purposes of such Registration, addressed to the Holders, the placement agent or sales agent, if any, and the Underwriters, if any, covering
such legal matters with respect to the Registration in respect of which such opinion is being given as the Holders, placement agent, sales
agent, or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters, and reasonably
satisfactory to a majority in interest of the participating Holders;


 


3.1.13 in the event of any Underwritten Offering,

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);


 






    9 


     


    

 


3.1.15 if the Registration involves the Registration
of Registrable Securities involving gross proceeds in excess of $50,000,000, 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 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 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 shares
of the 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 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.


 


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 or alleged untrue statement of material fact contained in the 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, but only to the extent that such untrue
statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however,
that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability
of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the
sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters,
their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent
as provided in the foregoing with respect to indemnification of the Company.


 


4.1.3 Any person entitled to indemnification
herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided
that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure
has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict
of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to
assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying
party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall
not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not
be obligated to pay the fees and expenses of more than one counsel (plus local counsel) for all parties indemnified by such indemnifying
party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between
such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the
consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects
by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement
does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from
all liability in respect to such claim or litigation.


 


4.1.4 The indemnification provided for under
this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or
any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each
Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified
party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.


  






    11 


     


    

 


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.

business day following the date on which it is mailed and, in the case of notices delivered by courier service, hand delivery, or facsimile,
at such time as it is delivered to the addressee (with the delivery receipt or the affidavit of messenger) or at such time as delivery

5.2 Assignment; No Third Party Beneficiaries.


 


5.2.1 This Agreement and the rights, duties and
obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in part.


 


5.2.2 Prior to the expiration of the Founder
Shares Lock-up Period or the Private Placement Lock-up Period, as the case may be, no Holder may assign or delegate such Holder’s
rights, duties or obligations under this Agreement, in whole or in part, except in connection with a transfer of Registrable Securities
by such Holder to a Permitted Transferee but only if such Permitted Transferee agrees to become bound by the transfer restrictions set
forth in this Agreement.


 


5.2.3 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.


 






    12 


     


    

 


5.2.4 This Agreement shall not confer any rights
or benefits on any persons that are not parties hereto, other than as expressly set forth in this Agreement and Section 5.2 hereof.


  


5.2.5 No assignment by any party hereto of such
party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company unless and until the Company shall
have received (i) written notice of such assignment as provided in Section 5.1 hereof and (ii) the written agreement
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 may
be executed in multiple counterparts (including facsimile or PDF counterparts), each of which shall be deemed an original, and all of
which together shall constitute the same instrument, but only one of which need be produced.


 


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, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION AND (II) THE VENUE FOR
ANY ACTION TAKEN WITH RESPECT TO THIS AGREEMENT SHALL BE ANY STATE OR FEDERAL COURT IN NEW YORK COUNTY IN THE STATE OF NEW YORK.


 


5.5 Amendments and Modifications. Upon

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 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 conflict between
any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.

upon the earlier of (i) the tenth anniversary of the date of this Agreement or (ii) the date as of which (A) all of the Registrable Securities
have been sold pursuant to a Registration Statement (but in no event prior to the applicable period referred to in Section 4(a)(3) of
the Securities Act and Rule 174 thereunder (or any successor rule promulgated thereafter by the Commission)) or (B) the Holders 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. The provisions of Section 3.5 and Article
IV shall survive any termination.
