(c)              
Section 2(a) shall immediately terminate and be of no further force and effect in the event that the applicable
Holder and its controlled Affiliates are not then in breach of this Section 2:


(i)                
the Company enters into a definitive agreement with an unaffiliated third party involving a Change of Control;


(ii)             
a bona fide tender offer or exchange offer with respect to the Equity Securities is commenced which, if successful,

or has failed to recommend against such transaction within ten (10) Business Days after the commencement thereof; or


(iii)           
the Company becomes subject to any voluntary or involuntary reorganization or restructuring process under Laws relating

the completion of the Company’s annual meeting of shareholders to be held in 2021 (including any adjournments or postponements

the Investor shall: (i) cause all Voting Securities then Beneficially Owned by it and its controlled Affiliates to be present,
in person or by proxy, at any meeting of the Company’s shareholders, so that all such Voting Securities shall be counted
for the purpose of determining the presence of a quorum at such meeting; and (ii) vote and cause to be voted all Voting Securities
then Beneficially Owned by it and its controlled Affiliates consistent with the recommendation of the Board with respect to any
business or proposal on which the shareholders of the Company are entitled to vote, other than with respect to an Extraordinary
Transaction. Neither the Investor nor any of its Affiliates shall have an obligation to vote its shares or submit written consents
in any prescribed manner in the case of any Extraordinary Transaction. For the avoidance of doubt,
nothing in this Agreement shall (i) restrict the Investor’s or its Affiliates’ ability to tender any of its Voting
Securities into a tender or exchange offer (regardless of whether or not the Board has recommended such tender or exchange offer)
or (ii) be considered a




    	7  





    	 



    


waiver of any appraisal or dissenters’ rights
with respect to any Extraordinary Transaction that the Investor or its Affiliates may be entitled
to under any applicable Law.  This Section 3 shall apply to a Holder that is an permitted assignee of the Investor
pursuant to Section 15(o) in the same manner it applies to the Investor; provided that the Investor transfers to
such Holder its Equity Securities constituting at least nine percent (9%) of the then-issued and outstanding Voting Securities
in connection with such assignment.


Section
4.               
Shelf Registration.


(a)              
Filing. As promptly as practicable after the date hereof but no later than ten (10) Business Days after the
Closing Date, and provided that the Company shall then qualify for the use of a Registration Statement on Form S-3 or any successor
form thereto, the Company shall prepare and file with the SEC a Registration Statement on Form S-3 or any successor form thereto,
or amend an existing Registration Statement on Form S-3 that has previously been filed with the SEC, for an offering to be made
on a delayed or continuous basis pursuant to Rule 415 under the Securities Act (a “Shelf Registration Statement”)
that covers all Registrable Securities then outstanding for an offering to be made on a delayed or continuous basis pursuant to
Rule 415 under the Securities Act (a “Shelf Registration”). If permitted under the Securities Act, such Shelf
Registration Statement shall be an “automatic shelf registration statement” as defined in Rule 405 under the Securities
Act.


(b)              
Effectiveness. The Company shall use its commercially reasonable efforts to (i) cause the Shelf Registration
Statement filed pursuant to this Section 4 to be declared effective by the SEC or otherwise become effective under the Securities
Act as promptly as practicable after the filing thereof and (ii) keep such Shelf Registration Statement continuously effective
and in compliance with the Securities Act and useable for the resale of Registrable Securities until such time as there are no
Registrable Securities remaining, including by filing successive replacement or renewal Shelf Registration Statements upon the
expiration of such Shelf Registration Statement; provided that the Company shall then qualify for the use of a Registration
Statement on Form S-3 or any successor form thereto.


(c)              
Additional Registrable Securities; Additional Selling Equityholders. At any time and from time to time that
a Shelf Registration Statement is effective, if a Holder of Registrable Securities requests (i) the registration under the Securities
Act of additional Registrable Securities pursuant to such Shelf Registration Statement or (ii) that such Holder be added as a selling
equityholder in such Shelf Registration Statement, the Company shall as promptly as practicable amend or supplement the Shelf Registration
Statement to cover such additional Registrable Securities and/or Holder; provided that the Company shall not be obligated
to make any such amendment or supplement more than once within any ninety (90) day period.


(d)              
Right to Effect Shelf Takedowns. Each Holder shall be entitled, at any time and from time to time when a Shelf
Registration Statement is effective, to sell any or all of the Registrable Securities covered by such Shelf Registration Statement
(a “Shelf Takedown”). A Holder shall give the Company prompt written notice of the consummation of a Shelf Takedown.
Each Holder agrees to use its commercially reasonable efforts to coordinate with the Company with respect to any sales of Registrable
Securities under a Shelf Registration Statement,




    	8  





    	 



    


including to provide written notice to the Company no later
than the end of the trading day immediately prior to any day that sales under a Shelf Registration Statement are effected.


(e)              
Underwritten Shelf Takedowns. A Holder intending to effect a Shelf Takedown shall be entitled to request by
written notice to the Company (an “Underwritten Shelf Takedown Notice”) that a Shelf Takedown be an Underwritten
Offering (an “Underwritten Shelf Takedown”). The Underwritten Shelf Takedown Notice shall specify the number
of Registrable Securities intended to be offered and sold by such Holder pursuant to the Underwritten Shelf Takedown. Promptly
after receipt of an Underwritten Shelf Takedown Notice (but in any event within two (2) Business Days), the Company shall give
written notice of the requested Underwritten Shelf Takedown to all other Holders of Registrable Securities and shall include in
such Underwritten Shelf Takedown, subject to Section 6, all Registrable Securities that are then covered by the Shelf Registration
Statement and with respect to which the Company has received a written request for inclusion therein from a Holder no later than
five (5) Business Days after the date of the Company’s notice. The Company shall not be required to facilitate an Underwritten
Shelf Takedown unless the expected aggregate gross proceeds from such offering (after giving effect to any withdrawal under Section
4(f)) are at least $75 million.


(f)               
Withdrawal. A Holder may, by written notice to the Company, withdraw the Registrable Securities of such Holder
from an Underwritten Shelf Takedown at any time prior to the pricing of an Underwritten Shelf Takedown. Upon receipt of notices
from all applicable Holders to such effect, the Company shall cease all efforts to consummate such Underwritten Shelf Takedown,
and such Underwritten Shelf Takedown shall not count for purposes of the limit on the number of Underwritten Shelf Takedowns in
Section 9(c).


(g)              
Selection of Underwriters. The Holder initially requesting an Underwritten Shelf Takedown shall have the right
to select the investment banking firm(s) and manager(s) to administer such Underwritten Shelf Takedown, subject to the approval
of (i) the other Holders (if any) who have requested to participate in such Underwritten Shelf Takedown (which approval shall not
be unreasonably withheld, conditioned or delayed) and (ii) the Company (which approval shall not be unreasonably withheld, conditioned
or delayed).


Section

Demand Registrations.

Right to Demand Registrations. At any time after the date hereof, any Holder may, by providing written notice
to the Company, request to sell all or part of its Registrable Securities pursuant to a Registration Statement separate from a
Shelf Registration Statement (a “Demand Registration”); provided that there is not then an effective
Registration Statement with respect to such Registrable Securities. Each request for a Demand Registration (a “Demand
Registration Request”) shall specify the number of Registrable Securities intended to be offered and sold by such Holder
pursuant to the Demand Registration and the intended method of distribution thereof, including whether it is intended to be an
Underwritten Offering. Promptly (but in any event within three (3) Business Days) after receipt of a Demand Registration Request,
the Company shall give written notice of the Demand Registration Request to all other Holders of Registrable Securities. As promptly
as practicable and no later than ten (10) Business Days after receipt of a Demand Registration Request, the Company shall register
all Registrable




    	9  





    	 



    


Securities (i) that have been requested to be registered
in the Demand Registration Request and (ii) subject to Section 6, with respect to which the Company has received a written
request for inclusion in the Demand Registration from a Holder no later than five (5) Business Days after the date on which the
Company has given notice to the Holders of the Demand Registration Request. The Company shall use its commercially reasonable efforts
to cause the Registration Statement filed pursuant to this Section 5(a) to be declared effective by the SEC or otherwise
become effective under the Securities Act as promptly as practicable after the filing thereof. A Demand Registration shall be effected
by way of a Registration Statement on Form S-3 or any similar short-form registration statement to the extent the Company is permitted
to use such form at such time. The Company shall not be required to effect a Demand Registration unless the expected aggregate
gross proceeds from the offering of the Registrable Securities to be registered in connection with such Demand Registration (after
giving effect to any withdrawal under Section 5(b)) are at least $75 million.


(b)              
Withdrawal. A Holder may, by written notice to the Company, withdraw the Registrable Securities of such Holder
from a Demand Registration at any time prior to the effectiveness of the applicable Registration Statement. Upon receipt of notices
from all applicable Holders to such effect, the Company shall cease all efforts to seek effectiveness of the applicable Registration
Statement, unless the Company intends to effect a primary offering of securities or a secondary offering of securities for shareholders
other than Holders pursuant to such Registration Statement, and such Demand Registration shall not count for purposes of the limit
on the number of Demand Registrations in Section 9(c).


(c)              
Selection of Underwriters. If a Demand Registration is an Underwritten Offering, the Holder initially requesting
such Demand Registration shall have the right to select the investment banking firm(s) to act as the managing underwriter(s) in
connection with the related offering, subject to the approval of (i) the other Holders (if any) who have requested to participate
in such Demand Registration (which approval shall not be unreasonably withheld, conditioned or delayed) and (ii) the Company (which
approval shall not be unreasonably withheld, conditioned or delayed).


Section
6.               
Inclusion of Other Securities; Priority. If a Demand Registration or Shelf Takedown involves an Underwritten
Offering, and the managing underwriters of such offering advise the Company and the Holders in writing that, in their opinion,
the number of Equity Securities proposed to be included in such Demand Registration or Underwritten Shelf Takedown, including all
Registrable Securities and all other Equity Securities proposed to be included in such offering, exceeds the number of Equity Securities
that can reasonably be expected to be sold in such offering without adversely affecting the success of the offering (including
the price, timing or distribution of the securities to be sold in such offering), the Company shall include in such Demand Registration
or Underwritten Shelf Takedown: (i) first, the Registrable Securities proposed to be sold by Holders in such offering; and
(ii) second, any Equity Securities proposed to be included therein by any other Persons (including Equity Securities to
be sold for the account of the Company and/or any other holders of Equity Securities), allocated, in the case of this clause (ii),
among such Persons in such manner as the Company may determine. If more than one Holder is participating in such Demand Registration
or Underwritten Shelf Takedown and the managing underwriters of such offering determine that




    	10  





    	 



    


only a limited number of Registrable Securities may be
included in such offering without reasonably being expected to adversely affect the success of the offering (including the price,
timing or distribution of the securities to be sold in such offering), then the Registrable Securities that are included in such
offering shall be allocated pro rata among the participating Holders on the basis of the number of Registrable Securities initially
requested to be sold by each such Holder in such offering.


Section
7.               
Piggyback Registrations.


(a)              
Whenever the Company proposes to register any Equity Securities under the Securities Act (other than a registration
(i) pursuant to a Registration Statement on Form S-8 (or other registration solely relating to an offering or sale to employees
or directors of the Company pursuant to any employee stock plan or other employee benefit arrangement), (ii) pursuant to a Registration
Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor
rule thereto) or (iii) in connection with any dividend or distribution reinvestment or similar plan), whether for its own account
or for the account of one or more shareholders of the Company (other than the Holders of Registrable Securities) (a “Piggyback
Registration”), the Company shall give prompt written notice to each Holder of Registrable Securities of its intention
to effect such a registration (but in no event less than ten (10) Business Days prior to the proposed date of filing of the applicable
Registration Statement and, subject to Section 7(b) and Section 7(c), shall include in such Registration Statement
and in any offering of Equity Securities to be made pursuant to such Registration Statement that number of Registrable Securities
requested to be sold in such offering by such Holder for the account of such Holder; provided, that the Company has received
a written request for inclusion therein from such Holder no later than five (5) Business Days after the date on which the Company
has given notice of the Piggyback Registration to Holders. The Company may terminate or withdraw a Piggyback Registration prior
to the effectiveness of such registration at any time in its sole discretion. If a Piggyback Registration is effected pursuant
to a Registration Statement on Form S-3 or the then-appropriate form for an offering to be made on a delayed or continuous basis
pursuant to Rule 415 under the Securities Act or any successor rule thereto (a “Piggyback Shelf Registration Statement”),
the Holders of Registrable Securities shall be notified by the Company of and shall have the right, but not the obligation, to
participate in any offering pursuant to such Piggyback Shelf Registration Statement (a “Piggyback Shelf Takedown”),
subject to the same limitations that are applicable to any other Piggyback Registration as set forth above.


(b)              
Priority on Primary Piggyback Registrations. If a Piggyback Registration or Piggyback Shelf Takedown is initiated
as a primary Underwritten Offering on behalf of the Company and the managing underwriters of the offering advise the Company in
writing that, in their opinion, the number of Equity Securities proposed to be included in such offering, including all Registrable
Securities and all other Equity Securities proposed to be included in such offering, exceeds the number of Equity Securities that
can reasonably be expected to be sold in such offering without adversely affecting the success of the offering (including the price,
timing or distribution of the securities to be sold in such offering), the Company shall include in such Piggyback Registration
or Piggyback Shelf Takedown: (i) first, Equity Securities that the Company proposes to sell in such offering; and (ii) second,
any Registrable Securities requested




    	11  





    	 



    


to be included in such offering by any Holders or any Equity
Securities proposed to be included in the offering by any other Person to whom the Company has a contractual obligation to facilitate
such offering, allocated, in the case of this clause (ii), pro rata among such Holders and Persons on the basis of the number of
Equity Securities initially proposed to be included by each such Holder or Person in such offering, up to the number of Equity
Securities, if any, that the managing underwriters determine can be included in the offering without reasonably being expected
to adversely affect the success of the offering (including the price, timing or distribution of the securities to be offered in
the offering).


(c)              
Priority on Secondary Piggyback Registrations. If a Piggyback Registration or a Piggyback Shelf Takedown is
initiated as an Underwritten Offering on behalf of a holder of Equity Securities to whom the Company has a contractual obligation
to facilitate such offering, other than Holders of Registrable Securities exercising rights pursuant to Section 5, for which
the specified priorities are in Section 6, and the managing underwriters of the offering advise the Company in writing that,
in their opinion, the number of Equity Securities proposed to be included in such offering, including all Registrable Securities
and all other Equity Securities requested to be included in such offering, exceeds the number of Equity Securities which can reasonably
be expected to be sold in such offering without adversely affecting the success of the offering (including the price, timing or
distribution of the securities to be sold in such offering), the Company shall include in such Piggyback Registration or Piggyback
Shelf Takedown: (i) first, Equity Securities that the Person demanding the offering pursuant to such contractual right
proposes to sell in such offering; and (ii) second, any Registrable Securities requested to be included in such offering
by the Holders or any Equity Securities proposed to be included in such offering by the Company or any other Person to whom the
Company has a contractual obligation to facilitate such offering, allocated, in the case of this clause (ii), pro rata among such
Holders and Persons on the basis of the number of Equity Securities initially proposed to be included by each such Holder or Person
in such offering, up to the number of Equity Securities, if any, that the managing underwriters determine can be included in the
offering without reasonably being expected to adversely affect the success of the offering (including the price, timing or distribution
of the securities to be offered in such offering).


(d)              
Selection of Underwriters. The Holders shall have no right to select the investment banking firm(s) to act
as the managing underwriter(s) in connection with a Piggyback Registration pursuant to this Section 7.


Section
8.               
Holdback Agreements.


(a)              
Holders of Registrable Securities. Each Holder of Registrable Securities that
holds or Beneficially Owns at least five percent (5%) of the outstanding Common Stock agrees that in connection with any
registered Underwritten Offering of Common Stock, and upon request from the managing underwriter(s) for such offering, such Holder
shall not, without the prior written consent of such managing underwriter(s), during such period as is reasonably requested by
the managing underwriter(s) (which period shall in no event be longer than three (3) days prior to and ninety
(90) days after the pricing of such offering), Transfer any Registrable Securities (subject to such exceptions as may be
agreed by the managing underwriter(s) and the Holders). The foregoing provisions of this Section 8(a) shall not apply to
offers or sales of




    	12  





    	 



    


Registrable Securities that are included in an offering pursuant
to Section 4, Section 5, Section 6, and Section 7 of this Agreement and shall be applicable to the
Holders of Registrable Securities only if, for so long as and to the extent that the Company, the
directors and executive officers of the Company and each selling shareholder included in
such offering are subject to the same restrictions. Each Holder of Registrable Securities agrees to execute and deliver
such other agreements as may be reasonably requested by the managing underwriter(s) that are consistent with the foregoing provisions
of this Section 8(a) and are necessary to give further effect thereto.


(b)              
 The Company. To the extent reasonably requested by the managing underwriter(s)
for the applicable offering, the Company shall not effect any sale registered under the Securities Act or other public distribution
of Equity Securities during the period commencing three (3) days prior to and ending ninety
(90) days (or for such shorter period as to which the managing underwriter(s) may agree) after the pricing of an Underwritten Offering
pursuant to Section 4, Section 5, and Section 7 of this Agreement,
other than a registration (i) pursuant to a Registration Statement on Form S-8 (or other registration solely relating
to an offering or sale to employees or directors of the Company pursuant to any employee equity plan or other employee benefit
arrangement), (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a transaction subject to Rule
145 under the Securities Act or any successor rule thereto) or (iii) in connection with any dividend or distribution reinvestment
or similar plan, and subject to such exceptions as may be agreed by the managing underwriter(s) and the Company, including exceptions
to permit sales of Common Stock by the Company under an “at-the-market” equity distribution program, if the managing
underwriter(s) determine that such sales would not be expected to adversely affect the success of the offering (including the price,
timing or distribution of the securities to be offered in such offering). Notwithstanding the foregoing, the Company shall not
be required to enter into any such holdback agreement or otherwise so agree during the consecutive ninety (90) day period immediately
following the expiration of any other holdback agreement or other such agreement it has entered into pursuant to this Section
8(b).


Section
9.               
Suspensions and other Limitations.


(a)              
The Company shall be entitled at any time by providing written notice to the Holders of Registrable Securities to
delay or suspend the filing, effectiveness or use of a Registration Statement or Prospectus (a “Suspension”)
if the Board determines in good faith that (i) proceeding with the filing, effectiveness or use of such Registration Statement
or Prospectus would reasonably be expected to require the Company to disclose any information the disclosure of which would have
a material adverse effect on the Company or its business and that the Company would not otherwise be required to disclose at such
time, (ii) the registration or offering proposed to be delayed or suspended would reasonably be expected to, if not delayed
or suspended, have a material adverse effect on any pending negotiation or plan of the Company to effect a bona fide merger, acquisition,
disposition, financing, reorganization, recapitalization or other similar transaction, in each case that, if consummated, would
be material to the Company, or (iii) a material corporate transaction has occurred or is probable and any financial statements
or pro forma financial information required to be included or incorporated by reference in a Registration Statement or Prospectus
by Regulation S-X are unavailable without unreasonable effort or expense; provided, that the Company shall not be
entitled to exercise a Suspension




    	13  





    	 



    


(A) more than twice during any one-year period or (B)
for a period exceeding sixty (60) days on any one occasion. The Company shall not register any securities for sale for its own
account or that of another shareholder during any Suspension. Each Holder who is notified by the Company of a Suspension pursuant
to this Section 9 shall keep the existence of such Suspension confidential and shall immediately discontinue (and direct
any other Person making offers or sales of Registrable Securities on behalf of such Holder to immediately discontinue) offers and
sales of Registrable Securities pursuant to such Registration Statement or Prospectus until the earlier of the expiration of such
Suspension or such time as it is advised in writing by the Company that the use of the Registration Statement or Prospectus may
be resumed and if applicable, is furnished by the Company with a supplemented or amended Prospectus as contemplated by Section
10(f). The Company shall use its commercially reasonable efforts to limit the length of any Suspension. Notice of the commencement
of any Suspension shall simply specify such commencement and shall not contain any facts or circumstances relating to such commencement
or any material non-public information. If the Company delays or suspends a Demand Registration, the Holder that initiated such
Demand Registration shall be entitled to withdraw its Demand Registration Request and, if it does so, such Demand Registration
Request shall not count against the limitations on the number of such Holder’s Demand Registrations set forth in Section
9(c).


(b)              
In the event the Updated Financial Statements are not available to the Company in accordance with Section 6.18 of
the Stock Purchase Agreement to the extent required by applicable securities Laws in order to enable the Company to fulfill any
of its obligations under Sections 4(a) and (b), Section 5(a), Section 6 and Section 9(c), then
such of the Company’s obligations to the extent so affected hereunder shall be tolled such that the Company shall comply
with such obligations within five (5) Business Days after the Company completes the preparation of such Updated Financial Statements
in compliance with the requirements of Regulation S-X of the SEC and to the extent required by applicable securities Laws in order
to enable the Company to fulfill its obligations hereunder.


(c)              
The Company shall not be required to effect more than two (2) total Underwritten Shelf Takedowns in any one-year
period and three (3) Demand Registrations pursuant to this Agreement; provided, however, that a registration shall
not count as a Demand Registration for purpose of this Section 9(c) unless and until the Holders of Registrable Securities
are able to register and sell at least ninety percent (90%) of the Registrable Securities requested to be included in such registration.


Section
10.           
Registration Procedures. If and whenever the Company is required to effect the registration of any Registrable
Securities pursuant to this Agreement, the Company shall use its commercially reasonable efforts to effect and facilitate the registration,
offering and sale of such Registrable Securities in accordance with the intended method of disposition thereof as promptly as is

(a)

Statement to become effective as promptly as practicable.
Before filing a Registration Statement or any amendments or supplements thereto (excluding, for the avoidance of doubt, the filing
of any document under the Exchange Act incorporated by reference therein), the Company shall, at the Company’s expense, furnish
to counsel to the Holders for such registration copies of all documents proposed to be filed, and give counsel to the Holders participating
in such registration a reasonable opportunity to review and comment on such documents and keep such Holders reasonably informed
as to the registration process;


(b)              
prepare and file with the SEC such amendments and supplements to any Registration Statement and the Prospectus used

requirements of the Securities Act with respect to the disposition of the Registrable Securities covered by such Registration Statement
in accordance with the intended method or methods of disposition by the sellers of such Registrable Securities set forth in such
Registration Statement or Prospectus;

thereto and all documents incorporated by reference therein) and such other documents in each case as such Holder may reasonably
request, including in order to facilitate the disposition of the Registrable Securities owned by such Holder (it being understood
that the Company consents to the use of the Prospectus and any amendment or supplement to the Prospectus by the Holders covered
by the Registration Statement and the underwriter or underwriters, if any, in connection with the offering and sale of the Registrable
Securities covered by the Prospectus or any amendments or supplements to the Prospectus);

requests and (ii) do any and all other acts and things that may be necessary or reasonably advisable to enable such Holder and
each underwriter, if any, to consummate the disposition of such Holder’s Registrable Securities in such jurisdiction(s);
provided, that the Company shall not be required to qualify generally to do business, subject itself to taxation or consent
to general service of process in any jurisdiction where it would not otherwise be required to do so but for its obligations pursuant
to this Section 10(d);


(e)

or any post-effective amendment thereto, when the same has become effective;

of the issuance by the SEC of any stop order suspending the effectiveness of such Registration Statement or the initiation
or threatening of any proceedings for any such purpose; and

of the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable
Securities for sale under the applicable securities or blue-sky laws of any jurisdiction;


(f)

to be delivered under the Securities Act, of the occurrence of any event that would cause the Prospectus included in such Registration
Statement to contain an untrue statement of a material fact or to omit any fact necessary to make the statements made therein not
misleading in light of the circumstances under which they were made, and, as promptly as practicable, prepare, file with the SEC
and furnish to such Holder a reasonable number of copies of a supplement or amendment to such Prospectus so that, as thereafter
delivered to the purchasers of such Registrable Securities, such Prospectus will not contain any untrue statement of a material
fact or omit to state any fact necessary to make the statements therein not misleading in light of the circumstances under which
they were made;


(g)              
promptly obtain the withdrawal or lifting of any stop order suspending the effectiveness of a Registration Statement,

not file or make any amendment to any Registration Statement with respect to any Registrable Securities, or any amendment
of or supplement to the Prospectus used in connection therewith, that refers to any Holder covered thereby by name or otherwise
identifies such Holder as the holder of any securities of the Company without the consent of such Holder (such consent not to be
unreasonably withheld or delayed), unless and to the extent such disclosure is required by Law;


(i)                
cause such Registrable Securities to be listed on each securities exchange on which the Common Stock is then listed
or, if the Common Stock is not then listed on any securities exchange, use its commercially reasonable efforts to cause such Registrable
Securities to be listed on a national securities exchange selected by the Company after consultation with the Holders participating
in such registration;

    	16  





    	 



    


business reasonably requested by such Holder or underwriter

by any such Holder, underwriter, attorney, accountant or agent in connection with such registration or offering and make senior
management of the Company and the Company’s independent accountants available for customary due diligence and drafting sessions;

(l)                
otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC,
and make available to its shareholders, as soon as reasonably practicable, an earnings statement (in a form that satisfies the
provisions of Section 11(a) of the Securities Act and Rule 158 under the Securities Act or any successor rule thereto) covering
the period of at least twelve (12) months beginning with the first (1st) day of the Company’s first full fiscal quarter after
the effective date of the applicable Registration Statement, which requirement shall be deemed satisfied if the Company timely
files complete and accurate information on Forms 10-K, 10-Q and 8-K under the Exchange Act and otherwise complies with Rule 158
under the Securities Act or any successor rule thereto;

(n)              
in the case of an Underwritten Offering of Registrable Securities, enter into such customary agreements (including

as any Holder participating in such offering or the managing underwriter(s) of such offering reasonably requests in order to expedite
or facilitate the disposition of such Registrable Securities;


(o)

cooperate with the Holders of the Registrable Securities to facilitate the timely preparation and delivery of certificates
representing the Registrable Securities to be sold pursuant to such Registration Statement free of any restrictive legends and

advisable to effect the registration, marketing and sale of such Registrable Securities contemplated by this Agreement.


Each Holder shall furnish to the Company
in writing such information regarding itself and the distribution proposed by it as the Company may reasonably request for use
in connection with a Registration Statement or Prospectus, and the Company shall not be obligated to effect any registration of
such Holder’s Registrable Securities unless and until such Holder shall have furnished to the Company in writing such information.
Each Holder agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished
to the Company by such Holder or of the occurrence of any event that would cause the Prospectus included in such Registration Statement
to contain an untrue statement of a material fact regarding such Holder or the distribution of such Registrable Securities or to
omit to state any material fact regarding such Holder or the distribution of such Registrable Securities required to be stated
therein or necessary to make the statements made therein not misleading in




    	18  





    	 



    


light of the circumstances under which they were made and
to furnish to the Company, as promptly as practicable, any additional information required to correct and update the information
previously furnished by such Holder such that such Prospectus shall not contain any untrue statement of a material fact regarding
such Holder or the distribution of such Registrable Securities or omit to state a material fact regarding such Holder or the distribution
of such Registrable Securities necessary to make the statements therein not misleading in light of the circumstances under which
they were made.


Section
11.           
Participation in Underwritten Offerings. No Person may participate in any Underwritten Offering pursuant to
this Agreement unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements
in customary form approved by the Persons entitled under this Agreement to approve such arrangements and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under
the terms of such underwriting arrangements; provided, that no Holder of Registrable Securities included in any Underwritten
Offering shall be required to make any representations or warranties to the Company or the underwriters (other than representations
and warranties regarding (A) such Holder’s ownership of its Registrable Securities to be sold in such offering; (B)
such Holder’s power and authority to effect such Transfer; and (C) such other matters as may be reasonably requested
by the managing underwriter(s)) or to undertake any indemnification obligations to the Company or the underwriters with respect
thereto, except to the extent otherwise provided in Section 13 hereof, mutatis mutandis. Any liability of any Holder
under an underwriting agreement entered into pursuant to this Section 11 shall be limited to liability arising from the
breach of its representations and warranties contained in that underwriting agreement and shall be limited to an amount equal to
the net amount received by that Holder from the sale of Registrable Securities pursuant to such Registration Statement.


Section
12.           
Registration Expenses.


(a)              
The Company shall pay directly or promptly reimburse all costs, fees and expenses (other than Selling Expenses) incident
to the Company’s performance of or compliance with this Agreement, including, without limitation,
(i) all SEC, Financial Industry Regulatory Authority and other registration and filing fees;
(ii) all fees and expenses associated with filings to be made with, or the listing of any Registrable Securities on, any securities
exchange or over-the-counter trading market on which the Registrable Securities are to be listed or quoted; (iii) all fees
and expenses of complying with securities and blue-sky laws (including fees and disbursements of counsel for the Company in connection
therewith); (iv) all printing, messenger, telephone and delivery expenses (including the cost of distributing Prospectuses in preliminary
and final form as well as any supplements thereto); (v) all fees and expenses incurred in connection with any “road show”
for Underwritten Offerings, including all costs of travel, lodging and meals; (vi) all transfer agent’s and registrar’s

and (ix) all fees and expenses




    	19  





    	 



    


of underwriters (other than Selling Expenses) customarily
paid by the issuers or sellers of securities (all such costs, fees and expenses, “Registration Expenses”). In
connection with each Shelf Registration, Shelf Takedown or Demand Registration initiated pursuant to this Agreement (but, for the
avoidance of doubt, not a Piggyback Registration), the Company shall reimburse the Holders covered by such registration for the
reasonable and documented fees and disbursements of one law firm chosen by the Holders of a majority of the number of Registrable
Securities included in such Shelf Registration, Shelf Takedown or Demand Registration Request, as applicable. Except as set forth
in the preceding sentence, each Holder shall pay the fees and expenses of any counsel engaged by such Holder and shall bear its
respective Selling Expenses associated with a registered sale of its Registrable Securities pursuant to this Agreement.


(b)              
The obligation of the Company to bear and pay the Registration Expenses shall apply irrespective of whether a registration,
once properly demanded or requested, becomes effective or is withdrawn or suspended; provided, that the Registration Expenses
for any Registration Statement withdrawn solely at the request of one (1) or more Holder(s) (unless withdrawn following commencement
of a Suspension) shall be borne by such Holder.


Section
13.           
Indemnification; Contribution.


(a)              
The Company shall, to the fullest extent permitted
by law, indemnify and hold harmless each Holder of Registrable Securities, any Person who is a “controlling person”
of such Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each such Person, a “Controlling
Person”), their respective direct and indirect general and limited partners, directors, officers, trustees, managers,
members, employees, agents, Affiliates and shareholders, and each other Person, if any, who acts on behalf of or controls any such
Holder or Controlling Person (each of the foregoing, a “Covered Person”) against any losses, claims, actions,
damages, liabilities and expenses, joint or several, to which such Covered Person may become subject under the Securities Act,
the Exchange Act, any state blue-sky securities laws, any equivalent non-U.S. securities laws or otherwise, insofar as such losses,
claims, actions, damages, liabilities or expenses arise out of or are based upon (i) any untrue or alleged untrue statement of
a material fact contained in or incorporated by reference in any Registration Statement, Prospectus, preliminary Prospectus, free
writing prospectus (as defined in Rule 405 under the Securities Act or any successor rule thereto) or any amendment thereof or
supplement thereto or any document incorporated by reference therein, (ii) any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein not misleading or (iii) any violation or alleged violation
by the Company of the Securities Act or any other similar federal or state securities laws or any rule or regulation promulgated
thereunder applicable to the Company and relating to any action or inaction required of the Company in connection with any registration
of securities, and the Company shall reimburse each Covered Person for any legal or other
expenses reasonably incurred by such Covered Person in connection with investigating, defending or settling any such loss, claim,
action, damage or liability; provided, that the Company shall not be so liable in
any such case to the extent that any loss, claim, action, damage, liability or expense arises out of or is based upon any such
untrue statement or alleged untrue statement, or omission or alleged omission, made or incorporated by reference in any such Registration
Statement, Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any
successor rule thereto) or any




    	20  





    	 



    


amendment thereof or supplement thereto or any document incorporated
by reference therein in reliance upon, and in conformity with, written information prepared and furnished to the Company by
such Covered Person expressly for use therein. This indemnity shall be in addition to any liability the Company may
otherwise have.


(b)              
In connection with any registration in which a Holder of Registrable Securities is participating, each such Holder
shall furnish to the Company in writing such information as the Company reasonably requests for use in connection with any such
Registration Statement or Prospectus and shall, to the fullest extent permitted by law, indemnify and hold harmless the Company,
its directors and officers, employees, agents, Affiliates and shareholders and any Person who is
a Controlling Person with respect to the Company against any losses, claims, actions, damages, liabilities and expenses, joint
or several, to which they or any of them may become subject under the Securities Act, the Exchange Act, any state blue-sky securities
laws, any equivalent non-U.S. securities laws or otherwise, insofar as such losses, claims, actions, damages, liabilities or expenses
arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Registration Statement,
Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any successor rule
thereto) or any amendment thereof or supplement thereto or (ii) any omission or alleged omission of a material fact required to
be stated therein or necessary to make the statements therein, in the case of any Prospectus, preliminary prospectus, free writing
prospectus or any supplement thereto, in light of the circumstances under which made, not misleading, but, in the case of each
of clauses (i) and (ii), only to the extent that such untrue statement or alleged untrue statement, or omission or alleged omission,
is made in such Registration Statement, Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under
the Securities Act or any successor rule thereto) or any amendment thereof or supplement thereto in reliance upon, and in conformity
with, written information prepared and furnished to the Company by such Holder expressly
for use therein, and such Holder shall reimburse the Company,
its directors and officers, employees, agents, Affiliates and shareholders and any Person
who is a Controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating, defending
or settling any such loss, claim, action, damage or liability; provided, that the obligation to indemnify pursuant
to this Section 13(b) shall be individual and several, not joint and several, for each participating Holder and shall not
exceed an amount equal to the net proceeds (after deducting Selling Expenses) actually received by such Holder in the sale of Registrable
Securities to which such Registration Statement or Prospectus relates. The Company and the Holders of the Registrable Securities
hereby acknowledge and agree that, unless otherwise expressly agreed to in writing by such Holders, the only information furnished
or to be furnished to the Company for use in any Registration Statement or Prospectus relating to the Registrable Securities or
in any amendment, supplement or preliminary materials associated with the same are statements specifically relating to (a) the
beneficial ownership of shares of Equity Securities by such Holder and its Affiliates, (b) the name and address of such Holder
and any other beneficial owner of such Holder’s Registrable Securities and (c) any additional information about such Holder
or the plan of distribution (other than for an underwritten offering) required by law or regulation to be disclosed in any such
document. This indemnity shall be in addition to any liability which such Holder may otherwise
have.


(c)              
Any Person entitled to indemnification hereunder shall give prompt written notice to the indemnifying party of any
claim with respect to which it seeks indemnification; provided,




    	21  





    	 



    


that any failure or delay to so notify the indemnifying party
shall not relieve the indemnifying party of its obligations hereunder, except to the extent that the indemnifying party is actually
and materially prejudiced by reason of such failure or delay. In case a claim or an action that is subject or potentially subject
to indemnification hereunder is brought against an indemnified party, the indemnifying party shall be entitled to participate in
and shall have the right, exercisable by giving written notice to the indemnified party as promptly as practicable after receipt
of written notice from such indemnified party of such claim or action, to assume, at the indemnifying party’s expense, the
defense of any such claim or action, with counsel reasonably acceptable to the indemnified party; provided, that any indemnified
party shall continue to be entitled to participate in the defense of such claim or action, with counsel of its own choice, but
the indemnifying party shall not be obligated to reimburse the indemnified party for any fees, costs and expenses subsequently
incurred by the indemnified party in connection with such defense unless (A) the indemnifying party has agreed in writing to pay
such fees, costs and expenses, (B) the indemnifying party has failed to assume the defense of such claim or action within a reasonable
time after receipt of notice of such claim or action, (C) having assumed the defense of such claim or action, the indemnifying
party fails to employ counsel reasonably acceptable to the indemnified party, (D) the use of counsel chosen by the indemnifying
party to represent the indemnified party would present such counsel with a conflict of interest or (E) the indemnified party has
reasonably concluded upon the advice of counsel that there may be one or more legal or equitable defenses available to it and/or
other any other indemnified party which are different from or additional to those available to the indemnifying party. Subject
to the foregoing sentence, no indemnifying party shall, in connection with any one claim or action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same general circumstances or allegations, be liable for
the fees, costs and expenses of more than one (1) firm of attorneys (in addition to any local counsel) for all indemnified parties.
The indemnifying party shall not have the right to settle a claim or action for which any indemnified party is entitled to indemnification
hereunder without the consent of the indemnified party, and the indemnifying party shall not consent to the entry of any judgment
or enter into or agree to any settlement relating to such claim or action, unless such judgment or settlement does not impose any
admission of wrongdoing or ongoing obligations on any indemnified party and includes as an unconditional term thereof the giving
by the claimant or plaintiff therein to such indemnified party, in form and substance reasonably satisfactory to such indemnified
party, of a full and final release from all liability in respect of such claim or action. The indemnifying party shall not be liable
hereunder for any amount paid or payable or incurred pursuant to or in connection with any judgment entered or settlement effected
with the consent of an indemnified party unless the indemnifying party has also consented to such judgment or settlement (such
consent not to be unreasonably withheld, conditioned or delayed).


(d)              
If the indemnification provided for in this Section 13 is held by a court of competent jurisdiction to be
unavailable to, or unenforceable by, an indemnified party in respect of any loss, claim, action, damage, liability or expense referred
to herein, then the applicable indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to
the amount paid or payable by such indemnified party as a result of such loss, claim, action, damage, liability or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party,
on the other hand, in connection with the statements, omissions or violations which resulted in such loss, claim, action, damage,
liability or expense as well as any other relevant equitable considerations. The




    	22  





    	 



    


relative fault of the indemnifying party, on the one hand,
and of the indemnified party, on the other hand, shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party, whether the violation of the Securities Act or any other federal
or state securities law or rule or regulation promulgated thereunder applicable to the Company and relating to any action or inaction
required of the Company in connection with any registration of securities was perpetrated by the indemnifying party or the indemnified
party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement,
omission or violation. The parties agree that it would not be just and equitable if contribution pursuant hereto were determined
by pro rata allocation or by any other method or allocation that does not take into account the equitable considerations referred
to in this Section 13(d). In no event shall the amount which a Holder of Registrable Securities may be obligated to contribute
pursuant to this Section 13(d) exceed an amount equal to the net proceeds (after deducting Selling Expenses) actually received
by such Holder in the sale of Registrable Securities that gives rise to such obligation to contribute. No indemnified party guilty
or liable of “fraudulent misrepresentation” within the meaning of Section 11(f) of the Securities Act shall be
entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.


(e)              
The provisions of this Section 13 shall remain in full force and effect regardless of any investigation made
by or on behalf of any indemnified party or any officer, director or Controlling Person of such indemnified party and shall survive
the Transfer of any Registrable Securities by any Holder.


Section
14.           
Rule 144 Compliance.


(a)              
With a view to making available to the Holders of Registrable Securities the benefits of Rule 144 and any other rule
or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration,
the Company shall:


(i)               
make and keep public information available, as those terms are understood and defined in Rule 144;


(ii)             
use commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents required
of the Company under the Securities Act and the Exchange Act; and


(iii)           
furnish to any Holder of Registrable Securities, promptly upon request, a written statement by the Company as to
its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act.


(b)              
To the extent permitted by applicable Law,
upon the Investor’s delivery to the Company of a certificate and opinion of counsel reasonably satisfactory to the Company
(it being agreed that an opinion of outside counsel of national standing shall be deemed reasonably satisfactory to the Company)
certifying that the Investor has held the shares of Common Stock acquired under the terms of the Stock Purchase Agreement
for the requisite holding period under Rule 144, that the Investor is not an “affiliate”
of the Company (as defined in Rule 144) and that




    	23  





    	 



    


such shares may be freely transferred without registration
under applicable securities laws, the Company shall, and shall cause its transfer agent to, use commercially reasonable efforts
to take all necessary actions as promptly as reasonably practicable following the delivery of such certificate to remove the applicable
legend from, and terminate any applicable stop transfer instructions with respect to, such shares of Common Stock in connection
with a transfer thereof by the Investor pursuant to Rule 144 as an non-affiliate (as defined in
Rule 144) of the Company.


Section
15.           
Miscellaneous.


(a)              
Termination. This Agreement shall terminate, with respect to any Holder and automatically without further
action, at such time as such Holder ceases to hold or Beneficially Own any Voting Securities; provided that the provisions
of Section 12, Section 13 and Section 15 shall survive such termination. Neither the provisions of this Section
15(a) nor the termination of this Agreement shall relieve (i) any party hereto from any liability of such party to any
other party incurred prior to such termination or (ii) any party hereto from any liability to any other party arising out
of or in connection with a breach of this Agreement.


(b)              
Amendment. The provisions of this Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the provisions of this Agreement may not be given, without
the prior written consent of the Company and each Holder that would be affected by such amendment, modification, supplement, waiver
or consent.


(c)              
No Waivers. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate
as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise
of any other right, power or privilege.


(d)              
No Inconsistent Agreements. Each of the Company and the Holders represents and warrants that (i) it has not
entered into, and agrees that it will not enter into, any agreement with respect to its securities that violates or subordinates
or is otherwise inconsistent with the rights granted and the obligations assumed under this Agreement, or provides rights that
are senior in priority to the rights granted under this Agreement and (ii) its Constituent Documents, as may be amended from time
to time, shall not at any time be inconsistent with the terms of this Agreement. Each of the parties hereto acknowledges and agrees
that if there is any inconsistency between the terms of this Agreement and the Stock Purchase Agreement,
the Stock Purchase Agreement shall prevail to the extent of the inconsistency, unless otherwise expressly agreed.


(e)              
Adjustments Affecting Registrable Securities. The Company shall use its commercially reasonable efforts to
not take any action, or permit any change to occur, with respect to its Equity Securities which would materially and adversely
affect the ability of a Holder to include the Registrable Securities held by such Holder in a registration undertaken pursuant
to this Agreement (including effecting a stock split or a combination of shares that would reasonably be expected to have such
an effect).


(f)               
Responsibility. The Investor shall be responsible for any breach or deemed breach of this Agreement by any
of its Affiliates or Representatives.

(g)              
 Expenses. Except as specifically provided herein, all fees and expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be paid by the party incurring such fees or expenses.

(i)                
Interpretation. The parties have participated jointly in negotiating and drafting this Agreement. In the event
that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by
the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of
any provision of this Agreement. When a reference is made in this Agreement to Sections, such reference shall be to a Section of
this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,”
“includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words
“but not limited to.” References to any Law or form (including in the definition thereof) shall be deemed to include
references to such Law or form as amended, modified, supplemented or replaced to or at the applicable time, and all references
to any section of any Law include any successor to such section (and in the case of statutes, include any rules and regulations
promulgated under such statute). References to “$” or “dollars” shall refer to United States dollars.


(j)                
Counterparts. This Agreement may be executed in two or more counterparts (including by email, facsimile or
other electronic means), all of which shall be considered one and the same agreement and shall become effective when counterparts
have been signed by each of the parties and delivered to the other party, it being understood that all parties need not sign the
same counterpart.


(k)              
Entire Agreement. This Agreement (including the documents and the instruments referred to herein), together
with the Stock Purchase Agreement, constitutes the entire agreement among the parties and supersedes all prior agreements and understandings,
both written and oral, among the parties with respect to the subject matter hereof.


(l)                
Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State
of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware
or any other jurisdiction) that would cause the application of the law of any jurisdiction other than the State of Delaware.


(m)            
Jurisdiction and Venue. The parties hereto hereby irrevocably submit to the jurisdiction of the Delaware Court
of Chancery or, in the event (but only in the event) that such court does not have subject matter jurisdiction over such action
or proceeding, in the United States District Court for the District of Delaware in respect of the interpretation and enforcement
of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated
hereby, and hereby waive, and agree not to assert, as a




    	26  





    	 



    


defense in any action, suit or proceeding for the interpretation
or enforcement hereof or of any such document, that it is not subject thereto or that such action, suit or proceeding may not be
brought or is not maintainable in the Delaware Court of Chancery or, in the event (but only in the event) that such court does
not have subject matter jurisdiction over such action or proceeding, in the United States District Court for the District of Delaware,
or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree
that all claims with respect to such action or proceeding shall be heard and determined in the Delaware Court of Chancery or, in
the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, in
the United States District Court for the District of Delaware. The parties hereto hereby consent to and grant the Delaware Court
of Chancery or, in the event (but only in the event) that such court does not have subject matter jurisdiction over such action
or proceeding, the United States District Court for the District of Delaware, jurisdiction over the person of such parties and,
to the extent permitted by law, over the subject matter of such dispute and agree that mailing of process or other papers in connection
with any such action or proceeding in the manner provided in Section 15(h) or in such other manner as may be permitted by
law shall be valid and sufficient service thereof. EACH OF THE PARTIES IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHTS TO TRIAL BY JURY IN CONNECTION WITH ANY PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.


(n)              
Specific Performance. Each party agrees that irreparable damage would occur in the event that any of the provisions
of this Agreement were not performed by it in accordance with their specific terms or were otherwise breached or threatened to
be breached. It is accordingly agreed that each party shall be entitled to enforce specifically the terms and provisions of this
Agreement and injunctive relief, in addition to being entitled to exercise all rights provided in this Agreement and granted by
law, it being agreed by the parties that the remedy at law, including monetary damages, for breach of any such provision will be
inadequate compensation for any loss, and that any defense or objection in any action for specific performance or injunctive relief
for which a remedy at law would be adequate is hereby waived.


(o)              
Assigns. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns and transferees. Neither this Agreement nor any right, benefit, remedy, obligation
or liability arising hereunder may be assigned by any party without the prior written consent of the other parties, and any assignment
without such consent shall be null and void and of no effect, except that (i) the Company may assign this Agreement at any time
in connection with a sale or acquisition of the Company, whether by merger, consolidation, sale of all or substantially all of
the Company’s assets or similar transaction, without the consent of the Holders (provided, that the successor or acquiring
Person agrees in writing to assume all of the Company’s rights and obligations under this Agreement) and (ii) the Investor
may assign any and all of its rights under this Agreement at any time to a transferee in connection with any Transfer to such transferee
of its Equity Securities constituting at least three percent (3%) of the issued and outstanding shares of Common Stock as of immediately
after the Closing (taking into account the issuance of the Share Consideration), subject to appropriate adjustment for any subsequent
stock split, stock dividend, stock combination, recapitalization or similar change in the capitalization of the Company (provided




    	27  





    	 



    


that such transferee executes and delivers a counterpart
to this Agreement in the form attached hereto as Exhibit A).


(p)              
No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto and their respective
successors and permitted assigns and transferees and nothing herein, express or implied, is intended to or shall confer upon any
other Person any legal or equitable right, benefit or remedy of any nature whatsoever, under or by reason of this Agreement. Notwithstanding
the previous sentence, the parties hereto hereby acknowledge that the Persons set forth in Section 13 shall be express third-party
beneficiaries of the obligations of the parties hereto set forth in Section 13.


(q)              
Severability. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted
in such manner as to be effective and valid under applicable Law, but if any provision or portion of any provision of this Agreement
is held to be invalid, illegal or unenforceable in any respect under any applicable Law in any jurisdiction, such invalidity, illegality
or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall
be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or unenforceable provision or portion thereof
shall be interpreted to be only so broad as is enforceable.


(r)               
Further Assurances. Each party to this Agreement shall cooperate and take such action as may be reasonably
requested by another party to this Agreement in order to carry out the provisions and purposes of this Agreement and the transactions
contemplated hereby.


(s)               
Delivery by Email, Facsimile or Other Electronic Transmission. This Agreement and any signed agreement or
instrument entered into in connection with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed
and delivered by means of a facsimile machine or by email delivery of a “.pdf” format data file, shall be treated in
all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as
if it were the original signed version thereof delivered in person. No party hereto or to any such agreement or instrument shall
raise the use of a facsimile machine or email delivery of a “.pdf” format data file to deliver a signature to this
Agreement or any amendment hereto or the fact that any signature or agreement or instrument was transmitted or communicated through
the use of a facsimile machine or email delivery of a “.pdf” format data file as a defense to the formation of a contract
and each party hereto forever waives any such defense.
