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

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 such 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 Corporation, in writing,
within five (5) days after the receipt by the Holder of the notice from the Corporation. Upon receipt by the Corporation of
any such written notification from a Requesting Holder(s), such Requesting Holder(s) shall be entitled to have their Registrable
Securities included in a Registration pursuant to such Demand Registration and the Corporation shall effect, as soon thereafter
as practicable, but not more than forty five (45) days immediately after the Corporation’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 Corporation be obligated to effect more than one (1) Registration for each

a Demand Registration under this subsection 2.1.1, or more than three (3) Registrations in the aggregate pursuant to
Demand Registrations under this subsection 2.1.1, with respect to any or all Registrable Securities; provided,

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 (subject to Section 2.1.4)

2.1.2        Effective
Registration. Notwithstanding the provisions of subsection 2.1.1 above or any other part of this Agreement, a Registration

with the Commission with respect to a Registration pursuant to a Demand Registration has been declared effective by the Commission
and (ii) the Corporation 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 Corporation in writing, but in no event later than five (5) days,
of such election; provided, further, that the Corporation 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 Corporation 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 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 Common Stock or other equity securities that the Corporation desires to sell and the 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,

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”))
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 Common Stock or other equity securities that the Corporation desires to

to such Demand Registration. Notwithstanding anything to the contrary in this Agreement, the Corporation shall be responsible for

2.2         Piggyback

2.2.1        Piggyback

use its best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable
Securities requested by the Holders pursuant to this subsection 2.2.1 to be included in a Piggyback Registration on the
same terms and conditions as any similar securities of the Corporation 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

(b)          If
the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Corporation

persons or entities, other than the Holders of Registrable Securities, 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

for any or no reason whatsoever upon written notification to the Corporation 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 Corporation (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 Corporation 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.

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 Corporation shall not be obligated
to effect such request through an Underwritten Offering. Within five (5) days of the Corporation’s receipt of a written
request from a Holder or Holders of Registrable Securities for a Registration on Form S-3, the Corporation 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 Corporation, in writing, within ten (10) days after the receipt by the Holder of the notice
from the Corporation. As soon as practicable thereafter, but not more than thirty (30) days after the Corporation’s
initial receipt of such written request for a Registration on Form S-3, the Corporation 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 Corporation 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 Corporation 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 $5,000,000.

2.4         Restrictions
on Registration Rights. If (A) during the period starting with the date sixty (60) days prior to the Corporation’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 Corporation initiated Registration and provided that the Corporation 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 Corporation and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer;

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 detrimental to the Corporation for such Registration Statement to be filed in the near future and that it is

to any Registrable Securities held by any Holder, until after the expiration of the Founder Shares Lock-Up Period or the Private

of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case
including all exhibits thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement
(including each preliminary Prospectus), and such other documents as the Underwriters and the Holders of Registrable Securities
included in such Registration or the legal counsel for any such Holders may request in order to facilitate the disposition of the
Registrable Securities owned by such Holders;


 


3.1.4        prior
to any public offering of Registrable Securities, use its best efforts to (i) register or qualify the Registrable Securities
covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United
States as the Holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution)
may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement
to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business and operations
of the Corporation and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable
Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions;
provided, however, that the Corporation 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 by the Corporation are then listed;


 




    	 	- 8 -	 



     


    

  


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 or its counsel;


 


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 Underwriter
to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Corporation’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 Corporation, prior to the release or disclosure
of any such information;


 


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


 


3.1.12      on
the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of
counsel representing the Corporation 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 assurances letters, and reasonably satisfactory to the Underwriter or, if there is none,
to a majority in interest of the participating Holders;


 


3.1.13      in
the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and customary
form, with the managing Underwriter of such offering;


 


3.1.14      make
available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve
(12) months beginning with the first day of the Corporation’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;


 


3.1.15      if
the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $25,000,000, use its
reasonable efforts to make available senior executives of the Corporation 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.


 




    	 	- 9 -	 



     


    

  


3.2         Registration
Expenses. The Registration Expenses of all Registrations shall be borne by the Corporation. 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 Corporation pursuant to a Registration initiated by the Corporation hereunder unless such person (i) agrees to sell such
person’s securities on the basis provided in any underwriting arrangements approved by the Corporation 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 Corporation 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 Corporation 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 Corporation 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 Corporation to make an Adverse Disclosure
or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Corporation for
reasons beyond the Corporation’s control, the Corporation 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 Corporation to be necessary for such purpose. In the
event the Corporation 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 Corporation 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 Corporation, at all times while it shall be reporting
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 Corporation 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 that are not otherwise publicly available
on the Commission’s EDGAR website. The Corporation 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, including providing any legal opinions. Upon the request of any Holder, the Corporation shall deliver
to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

INDEMNIFICATION
AND CONTRIBUTION


 


4.1         Indemnification.


 


4.1.1        The
Corporation 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 actual and reasonable 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 Corporation
by such Holder expressly for use therein. The Corporation shall indemnify the Underwriters, their officers and directors and each
person who controls such Underwriters (within the meaning of the Securities Act) as may be provided in any Underwriting or similar
agreement entered into by the Corporation and the Underwriters relating to an Underwritten Offering.


 




    	 	- 10 -	 



     


    

  


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


 


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


 


4.1.4        The
indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by
or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive
the transfer of securities. The Corporation 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 Corporation’s
or such Holder’s indemnification is unavailable for any reason.


 


4.1.5        If
the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold
harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the
indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified
party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether
any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to
state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the
indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct
or prevent such action; provided, however, that the liability of any Holder under this subsection 4.1.5 shall
be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount
paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject
to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges
or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that
it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined by pro rata allocation
or by any other method of allocation, which does not take account of the equitable considerations referred to in this subsection
4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall
be entitled to contribution pursuant to this subsection 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

5.2         Assignment;
No Third Party Beneficiaries.


 


5.2.1        This
Agreement and the rights, duties and obligations of the Corporation hereunder may not be assigned or delegated by the Corporation
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 and other applicable letter agreements.


 


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

to be bound by the terms and provisions of this Agreement (which may be accomplished by an addendum or certificate of joinder to

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.

OF SUCH JURISDICTION.


 


5.5         Amendments
and Modifications. Upon the written consent of the Corporation 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 its capacity
as a holder of the shares of capital stock of the Corporation, 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 Corporation
and any other party hereto or any failure or delay on the part of a Holder or the Corporation in exercising any rights or remedies
under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Corporation. 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 Corporation represents and warrants that no person, other than a Holder of Registrable Securities,
has any right to require the Corporation to register any securities of the Corporation for sale or to include such securities of
the Corporation in any Registration filed by the Corporation for the sale of securities for its own account or for the account
of any other person. Further, the Corporation 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.


 


5.7         Term.
This Agreement shall terminate 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(3) of the Securities Act and Rule 174 thereunder) or (B) all
such Securities cease to be Registrable Securities. The provisions of Section 3.5 and Article IV shall
survive any termination.
