Article
II

COVENANTS

 

Section
2.1    
Stockholder Nominees.  

 

(a)    The Stockholders shall initially have the right to designate three (3) individuals to be nominated as Directors (the “Stockholder
Nominees” and each, a “Stockholder Nominee”), and the total number of Stockholder Nominees that the Stockholders
are entitled to so designate shall be subsequently adjusted from time to time pursuant to Section 2.1(b). Notwithstanding anything in
this Agreement to the contrary, and without limiting the generality of Section 2.1(c), each designee of the Stockholders to be nominated
as Directors must be an Eligible Designee.

 

(b)    

 

(i)    
If, on the record date for any meeting of stockholders of the Company following the Effective Time (the “Applicable
Meeting”) at which Directors are to be elected, the aggregate number of shares of Common Stock beneficially owned by the Scott
Family Stockholders, as a percentage of the aggregate number of shares of Common Stock then issued and outstanding (the “Common
Ownership Percentage”), constitutes less than the then applicable Stockholder Nominee Ownership Threshold, then the number of
Stockholder Nominees shall be reduced, to the total number set forth opposite the Stockholder Nominee Ownership Threshold which represents
the Common Ownership Percentage of the Scott Family Stockholders at such time; provided that the Stockholders shall deliver, no
later than three business days prior to the Applicable Meeting, a report that sets forth the number of shares of Common Stock held by
the Scott Family Stockholders individually and in the aggregate, as of the date of delivery of such report (the “Annual Report”);
provided, further (x) the Stockholders shall provide prior written notice to the Company of any changes in the number
of shares held by the Scott Family Stockholders after delivery of the Annual Report and before the record date for the Applicable Meeting
and (y) such written notice shall provide the number of shares of Common Stock held by the Scott Family Stockholders individually and
in the aggregate taking into account any such change provided in clause (x).

 

(ii)    
Upon any reduction in the number of Stockholder Nominees required by Section 2.1(b)(i), effective at and after the Applicable
Meeting, the number of Stockholder Nominees to which the Stockholders are entitled to designate under this Section 2.1 shall be the total
number set forth opposite the Stockholder Nominee Ownership Threshold which represents the Common Ownership Percentage of the Scott Family
Stockholders at such time. In the case that the number of Stockholder Nominees is

 

    

     

    

so
reduced, and the existing term in office of Stockholder Nominees extends beyond the date of the Applicable Meeting (such that, absent
resignation on the Applicable Meeting, the Stockholder Nominees remaining on the Board would exceed the number of Stockholder Nominees
to which the Stockholders are entitled), then at the request of the Company the Stockholders shall cause one or more of the Stockholder
Nominees (as designated by the Stockholders in the case that the number of Stockholder Nominees is reduced to one (1) or to two (2))
to resign from the Board effective at the Applicable Meeting, and all rights under this Section 2.1 in respect of such Stockholder Nominee(s)
shall be terminated and be of no further force and effect; provided that Section 2.6 shall survive any such termination. As a
condition to any Stockholder Nominee’s appointment or election to the Board, such Stockholder Nominee shall deliver to the Board
an irrevocable resignation letter which may be accepted by the Board upon the date on which the number of Stockholder Nominees is reduced
pursuant to the preceding sentence (and subject to the ability of the Stockholders to designate which Stockholder Nominee or Stockholder
Nominees to remove in the case that the number of Stockholder Nominees is reduced to one (1) or to two (2)). Once the number of Stockholder
Nominees has been reduced, it will not subsequently be increased even if the Stockholders acquire Beneficial Ownership of additional
Common Stock such that the number of Stockholder Nominees then serving on the Board is less than the number of Stockholder Nominees set
forth opposite the Stockholder Nominee Ownership Threshold which represents the Stockholders’ Common Ownership Percentage at such
time.

 

(iii)    
Subject to the other provisions of this Agreement, the Company shall include each Stockholder Nominee to which the Stockholders
are entitled to designate under this Section 2.1 on the Company’s slate of nominees for election as Directors at any applicable
meeting of stockholders at which Directors are to be elected and shall, to the fullest extent permitted by applicable Law, use its reasonable
best efforts (and in any event at least the same level of efforts used for the Company’s other Director nominees) to cause each
such Stockholder Nominee to be elected and maintained in office as a Director (including, without limitation, using its reasonable best
efforts to solicit from the stockholders of the Company eligible to vote for the election of Directors proxies in favor of the election
of each such Stockholder Nominee at any meeting of stockholders held to elect Directors). Subject to Section 2.1(c) and to the Company’s
required efforts set forth in this Section 2.1(b)(iii) with respect to Stockholder Nominees, if a Stockholder Nominee resigns or is otherwise
unavailable to serve as a Director, the Stockholders shall have the exclusive right to designate the replacement for such Stockholder
Nominee for so long as the Stockholders have the right to designate such Stockholder Nominee and the Company shall, consistent with its
obligations set forth in the immediately preceding sentence, cause any such replacement Stockholder Nominee to be promptly appointed or
elected to the Board.

 

(iv)     
For purposes of this Agreement, the “Stockholder Nominee Ownership Thresholds” shall be as follows:

 

    

     

    

	Common Ownership Percentage	Total Number of Stockholder Nominees
	Greater than or equal to 15%	3
	Greater than or equal to 10% but less than 15%	2
	Greater than or equal to 5% but less than 10%	1
	Less than 5%	0

 

(c)    
Notwithstanding anything in this Agreement to the contrary, neither the Company nor the Board shall be under any obligation
to nominate or appoint to the Board, or solicit votes for, any Person pursuant to Section 2.1, in event that: (i)  the election
of such Person to the Board would cause the Company to not be in compliance with applicable Law, (ii) such Person has been the subject
of any event required to be disclosed pursuant to Items 2(d) or 2(e) of Schedule 13D under the Exchange Act or Item 401(f) of Regulation
S-K of the Securities Act (for the avoidance of doubt, excluding bankruptcies) involving an act of moral turpitude by such individual
or is subject to any order, decree or judgment of any Governmental Entity prohibiting service as a director of any public company, (iii)
such Person fails to satisfy the mandatory director qualification and eligibility criteria required by any applicable SEC rules, rules
of any exchange on which the Company’s securities are then traded, or other binding legal requirements of the Company, or otherwise
fails to be reasonably acceptable to the Governance and Nominating Committee of the Board applying standards consistent with past practice
in evaluating Scott family director nominees or (iv) such Person does not qualify as an Eligible Designee. In the event a Person nominated
by the Stockholders as a Stockholder Nominee is not nominated or appointed to the Board as a result of a failure to satisfy any of the
requirements described in clauses (i) through (iv) of the immediately preceding sentence, the Stockholders will be permitted to designate
a replacement Stockholder Nominee (which replacement Stockholder Nominee will also be subject to the requirements of this Section 2.1(c)). 

 

(d)    
The Stockholder Nominees shall be entitled to attend meetings of any Committee on a non-voting basis, in each case, in a
manner consistent with the existing practice of the Board as of prior to the date of this Agreement.

 

Section
2.2    
Board Observers.

 

(a)    
For so long as the Stockholders are entitled to designate one or more Stockholder Nominees pursuant to Section 2.1, at any
time following the Effective Time, the Stockholders shall have the right to designate an equal number of representatives to act as a non-voting
observer of meetings of the Board and any Committee (in each case, except to the extent excluded therefrom pursuant to Section 2.2(d))
(each, a “Stockholder Board Observer”), as the number of Stockholder Nominees to which the Stockholders are so entitled
to designate at such time, and the total number of Stockholder Board Observers shall be subsequently adjusted from time to time concurrently
with any adjustment to the number of Stockholder Nominees that the Stockholders are entitled to so designate pursuant to Section 2.1(b).
Notwithstanding anything in this Agreement to the contrary, and without limiting the generality of Section 2.2(f), each designee

 

    

     

    

of
the Stockholders to act as a non-voting observer of meetings of the Board and any Committee must be an Eligible Designee.

 

(b)    
The Company agrees that each Stockholder Board Observer shall be entitled to attend, in a non-voting observer capacity,
all meetings of the Board and any Committees (in each case, except to the extent excluded therefrom pursuant to Section 2.2(d)) for the
purposes of permitting such Stockholder Board Observer to: (i) have current information with respect to the affairs of the Stockholders
and the actions taken by the Board, (ii) provide, when requested, input and advice to the Board or Committee at such time with respect
thereto, and (iii) consider and discuss, in his or her capacity as a stockholder of the Company, all Confidential Information received
from the Company with the Stockholders. As a non-voting observer, any Stockholder Board Observer shall be provided with (concurrently
with delivery to the Directors and in the same manner delivery is made to them) copies of all notices, minutes, consents, and all other
materials or information (financial or otherwise) that are provided to the Directors with respect to a meeting or any written consent
in lieu of meeting (except to the extent such Stockholder Board Observer has been excluded therefrom pursuant to Section 2.2(d)).

 

(c)    
In no event shall any Stockholder Board Observer (i) be deemed to be a member of the Board or such Committees, (ii) have
the right to vote on any matter under consideration by the Board or such Committees or otherwise have any power to cause the Company to
take, or not to take, any action, or (iii) have or be deemed to have, or otherwise be subject to, any duties (fiduciary or otherwise)
to the Company or its stockholders or any duties (fiduciary or otherwise) otherwise applicable to the Directors of the Company.

 

(d)    
Notwithstanding anything to the contrary in this Agreement, the Company shall be entitled, and does hereby expressly reserve
the right, to withhold any materials or information and to exclude any Stockholder Board Observer from all or any portion of any meeting
if and solely to the extent:

 

(i)    
access to such materials or information or attendance at such meeting would reasonably be expected to adversely affect the
attorney-client privilege between the Company and its counsel;

 

(ii)    
access to such materials or information or attendance at such meeting would reasonably be expected to result in disclosure
of confidential supervisory information to the Stockholder Board Observer;

 

(iii)    
the Stockholder Board Observer is a competitor of the Company, owns a material interest in a competitor of the Company or
the Stockholder Board Observer has a material business or financial interest in the matter to be discussed by the Board or Committee;
or

 

(iv)     
such meeting is an executive session limited solely to independent director members or other directors of the Board, independent
auditors, and/or legal counsel, as the Board may designate, or such Stockholder Board Observer would not meet the applicable standards
for independence adopted by The NASDAQ Stock Market, or such other exchange on which the Company’s securities are then traded (assuming
for

 

    

     

    

purposes
of the analysis that such Stockholder Board Observer were a member of the Board).

 

(e)    
Upon any reduction in the number of Stockholder Nominees required by ‎Section 2.1(b)(i) at any time following
the Effective Time, the number of Stockholder Board Observers that the Stockholders have a right to designate under this ‎Section
2.2 shall be reduced by the same number of Stockholder Nominees that are required to resign pursuant to ‎Section 2.1(b)(ii)
(and the Stockholders shall designate which Stockholder Board Observers to remove in the case that the number of Stockholder Board Observers
is reduced to one (1) or to two (2)), and all rights under this ‎Section 2.2 in respect of such Stockholder Board Observer(s)
shall be terminated and be of no further force and effect, provided that ‎Section 2.6 shall survive any such termination.
Once the number of Stockholder Board Observers has been reduced as a result in a reduction to the number of Stockholder Nominees, it will
not subsequently be increased even if the Stockholders acquire Beneficial Ownership of additional Common Stock such that the number of
Stockholder Nominees then serving on the Board is less than the number of Stockholder Nominees set forth opposite the Stockholder Nominee
Ownership Threshold which represents the Stockholders’ Common Ownership Percentage at such time.  

 

(f)     
Notwithstanding anything in this Agreement to the contrary, the Board shall not be obligated to accept or recognize a Person
as a Stockholder Board Observer for purposes of this Agreement if (i) such Person’s role as a Stockholder Board Observer would
cause the Company to not be in compliance with applicable Law, (ii) such Person has been the subject of any event required to be disclosed
pursuant to Items 2(d) or 2(e) of Schedule 13D under the Exchange Act or Item 401(f) of Regulation S-K of the Securities Act (for the
avoidance of doubt, excluding bankruptcies) involving an act of moral turpitude by such individual or is subject to any order, decree
or judgment of any Governmental Entity prohibiting service as a director of any public company, (iii)  such Person fails to
complete reasonable and customary onboarding documentation, including providing reasonably required information to the Company, and executing
a Board Observer and Confidentiality Agreement or other confidentiality agreement, in each case to the extent such requirements are consistent
with those applicable to the other observers of the board of directors of the Company or (iv) such Person does not qualify as an Eligible
Designee. In the event the Stockholders designate a Person that is not entitled to be designated as a Stockholder Board Observer as a
result of a failure to satisfy any of the requirements described in clauses (i) through (iv) of the immediately preceding sentence, the
Stockholders will be permitted to designate a replacement Stockholder Board Observer (which replacement Stockholder Board Observer will
also be subject to the requirements of this Section 2.2(f)).

Article
IV

REGISTRATION RIGHTS

 

Section
4.1    
Shelf Registration.

 

(a)    
Following demand by any Stockholder after expiration of the Lock-Up Period, the Company shall as promptly as practicable
(i) prepare and file with the SEC 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 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 or any successor
rule thereto (a “Shelf Registration”), (ii) amend an existing registration statement so that it is usable for Shelf
Registration and an offering on a delayed or continuous basis of Registrable Securities, or (iii) file a prospectus supplement that shall
be deemed to be a part of an existing registration statement in accordance with Rule 430B under the Securities Act that is usable for
Shelf Registration and an offering on a delayed or continuous basis of Registrable Securities (as applicable, a “Shelf Registration
Statement”). 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)    
Effective Registration Statement. The Company shall use its best efforts to (i) cause the Shelf Registration Statement
filed pursuant to Section 4.1(a) 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,
this Agreement is terminated in accordance with its terms, or the Company is no longer eligible to maintain a Shelf Registration Statement,
including by filing successive replacement or renewal Shelf Registration Statements upon the expiration of such Shelf Registration Statement.

 

(c)    
Additional Registrable Securities; Additional Selling Stockholders. At any time and from time to time that a Shelf
Registration Statement is effective, if a Scott Family Stockholder holding Registrable Securities requests (i) the registration under
the Securities Act of additional Registrable Securities pursuant to such Shelf Registration Statement or (ii) that such Scott Family Stockholder
be added as a selling stockholder 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 Stockholder.

 

    

     

    

(d)    
 Right to Effect Shelf Takedowns. Each Scott Family Stockholder 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”); provided, that any Shelf Takedown that is an Underwritten Shelf Takedown shall
be subject to Section 4.1(e). A Scott Family Stockholder shall give the Company prompt written notice of the consummation of a Shelf Takedown. 

 

(e)    
Underwritten Shelf Takedowns. A Stockholder intending to effect a Shelf Takedown, shall be entitled to request, by
written notice to the Company (an “Underwritten Shelf Takedown Notice”), that the 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 Stockholder pursuant to the Underwritten Shelf Takedown and the intended method of
distribution. 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 Scott Family Stockholders and shall include in such
Underwritten Shelf Takedown, subject to Section 4.3, 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 one or more Scott Family Stockholders
no later than five (5) business days (or, in the case of an Underwritten Shelf Takedown structured as a block trade, two (2) business
days) after the date of the Company’s notice. The Company shall not be required to facilitate an Underwritten Shelf Takedown (i)
unless the Aggregate Offering Price from such offering is at least $50,000,000, (ii) in the case of a marketed underwritten offering (and,
for the avoidance of doubt, excluding any underwritten block trade), more than two (2) times in the aggregate in any 12-month period,
and (iii) in the case of an underwritten block trade, more than four (4) times in the aggregate in any 12-month period.

 

(f)     
Selection of Underwriters. The Initiating Holder of an Underwritten Shelf Takedown shall have the right to select
the investment banking firm(s) and manager(s) to administer such Underwritten Shelf Takedown (including which such underwriters will serve
as lead or co-lead), subject to the approval of the Company (which approval shall not be unreasonably withheld, conditioned or delayed).

 

Section
4.2    
Demand Registrations.

 

(a)    
Right to Demand Registrations. If the Company is not eligible under applicable Law to register Registrable Securities
by way of a Registration Statement on Form S-3 pursuant to Section 4.1, any Stockholder after expiration of the Lock-Up Period 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”). 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 Stockholder
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 two (2) business days) after receipt of a Demand Registration Request, the Company shall give
written notice of the Demand Registration Request to all other Scott Family Stockholders that hold Registrable Securities. As promptly
as practicable after receipt of a Demand Registration Request, the Company shall register all Registrable Securities (i) that have been
requested to be registered in

 

    

     

    

the
Demand Registration Request and (ii) subject to Section 5.3, with respect to which the Company has received a written request for inclusion
in the Demand Registration from one or more Scott Family Stockholders no later than fifteen (15) days after the date on which notice
was given to Scott Family Stockholders of the Demand Registration Request. The Company shall use its best efforts to cause the Registration
Statement filed pursuant to this Section 4.2(a) to be declared effective by the SEC or otherwise become effective under the Securities
Act as promptly as practicable after the filing thereof. The Company shall not be required to effect a Demand Registration unless the
Demand Registration includes Registrable Securities in an amount not less than the Minimum Amount.

 

(b)    
Number of Demand Registrations. The Stockholders shall be entitled to request up to two (2) Demand Registrations
in the aggregate (which, for the avoidance of doubt, shall be in addition to any Shelf Registration pursuant to Section 4.1, other than
any Underwritten Shelf Takedown, which shall be deemed a Demand Registration for these purposes and count towards such maximum number
of Demand Registrations) during any 12-month period.

 

(c)    
Withdrawal. A Scott Family Stockholder may, by written notice to the Company, withdraw its Registrable Securities
from a Demand Registration at any time prior to the effectiveness of the applicable Registration Statement. Upon receipt of notices from
all applicable Scott Family Stockholders to such effect, or if such withdrawal shall reduce the Aggregate Offering Price for the offering
of the Registrable Securities to be registered in connection with such Demand Registration below the Minimum Amount, 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 pursuant to such Registration Statement, provided that such Demand Registration Request shall not count against the
limitation on the number of such Stockholder’s Demand Registrations set forth in Section 4.2(b). In the event that all applicable
Scott Family Stockholders withdraw their Registrable Securities from a Demand Registration and the withdrawal is a Permissible Withdrawal,
such Demand Registration Request shall not count against the limitation on the number of Demand Registrations set forth in Section 4.2(b).

 

(d)    
Selection of Underwriters. If a Demand Registration is an underwritten offering, the Initiating Holder shall have
the right to select the investment banking firm(s) to act as the managing underwriter(s) in connection with such offering (including which
such managing underwriters will serve as lead or co-lead), subject to the approval of the Company (which approval shall not be unreasonably
withheld, conditioned or delayed).

 

Section
4.3    
Inclusion of Other Securities; Priority. The Company shall not include in any Demand Registration or Shelf Takedown
any securities that are not Registrable Securities without the prior written consent of the Stockholder(s) holding the Registrable Securities
participating in such Demand Registration or Shelf Takedown. If a Demand Registration or Shelf Takedown involves an underwritten offering
and the managing underwriters of such offering advise the Company and the Scott Family Stockholders 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 the Initiating
Holder and the Participating Holders pro rata based on the number of Registrable Securities proposed to be sold by the Initiating Holder
and each Participating Holder, 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 Participating Holder is participating
in such Demand Registration or Underwritten Shelf Takedown and the managing underwriters of such offering determine that 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 Participating Holder in such offering.

 

Section
4.4    
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), (iii)
in connection with any dividend or distribution reinvestment or similar plan or (iv) that is a Demand Registration or Shelf Takedown hereunder),
whether for its own account or for the account of one or more stockholders of the Company (a “Piggyback Registration”),
the Company shall give prompt written notice to each Scott Family Stockholder of its intention to effect such a registration (but in no
event less than ten (10) days prior to the proposed date of filing of the applicable Registration Statement, or, in the case of a previously
effective Registration Statement, the applicable prospectus supplement) and, subject to Section 4.4(b) and Section 4.4(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 Scott Family Stockholder for the account of such Scott Family
Stockholder, provided that the Company has received a written request for inclusion therein from such Scott Family Stockholder
no later than three (3) days after the date on which the Company has given notice of the Piggyback Registration to Scott Family Stockholders.
The Company may terminate or withdraw a Piggyback Registration prior to the effectiveness of such registration at any time in its sole
discretion, subject to any other contractual obligations between the Company and any other holders of Equity Securities with respect to
such Piggyback Registration. 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 Scott Family Stockholders 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. A Scott Family Stockholder may, by written notice to the

 

    

     

    

Company,
withdraw its Registrable Securities from a Piggyback Registration at any time prior to the effectiveness of the applicable Registration
Statement.

 

(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, the Equity Securities that the Company proposes to sell in such offering; (ii) second, any Registrable Securities
requested to be included therein by any Scott Family Stockholders, allocated, in the case of this clause (ii), pro rata among such Scott
Family Stockholders on the basis of the number of Registrable Securities initially proposed to be included by each such Scott Family Stockholder
in such offering, up to the number of Registrable 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); and (iii) third, any Equity Securities proposed to be included in such offering
by any other Person to whom the Company has a contractual obligation to facilitate such offering, allocated, in the case of this clause
(iii), pro rata among such Persons on the basis of the number of Equity Securities initially proposed to be included by each such 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).

 

(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 the Stockholders, 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,
the Equity Securities that the Person demanding the offering pursuant to such contractual right proposes to sell in such offering; (ii)
second, any Registrable Securities requested to be included therein by any Scott Family Stockholders, allocated, in the case of
this clause (ii), pro rata among such Scott Family Stockholders on the basis of the number of Registrable Securities initially proposed
to be included by each such Scott Family Stockholder in such offering, up to the number of Registrable 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); and (iii) third, any Equity Securities
proposed to be sold for the account of the Company in such offering and any Equity Securities proposed to be included in such offering
by any other Person to whom

 

    

     

    

the
Company has a contractual obligation to facilitate such offering, allocated, in the case of this clause (iii), pro rata among the Company
and such Persons on the basis of the number of Equity Securities initially proposed to be included by the Company and each such other
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. If a Piggyback Registration or Piggyback Shelf Takedown is initiated as a primary underwritten
offering on behalf of the Company, the Company shall have the right to select the investment banking firm(s) to act as the managing underwriter(s)
in connection with such offering. 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, the right to select
the investment banking firm(s) to act as the managing underwriter(s) in connection with such offering shall be governed by such applicable
contractual arrangement between the Company and such holder of Equity Securities, provided that such managing underwriter shall
be reasonably acceptable to the Scott Family Stockholder or Scott Family Stockholders holding a majority of the Registrable Securities
proposed to be included in such Piggyback Registration or Piggyback Shelf Takedown (such approval not to be unreasonably withheld, conditioned
or delayed); provided, further, that such Scott Family Stockholder or Scott Family Stockholders may designate a co-managing
underwriter to participate in the Piggyback Registration or Piggyback Shelf Takedown, in each case to the extent permitted by such applicable
contractual arrangement between the Company and such holder of Equity Securities.

 

Section
4.5    
Holdback Agreements.

 

(a)    
Stockholders of Registrable Securities. Each Initiating Holder and Participating Holder agrees that in connection
with any underwritten Demand Registration, Underwritten Shelf Takedown or a registered underwritten offering of shares of Common Stock
by the Company in a primary offering for its own account, and upon written request from the managing underwriter(s) for such offering,
such Stockholder 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 seven (7) days prior to and sixty (60) days after the pricing
of such offering), effect any public sale or distribution of any Similar Securities to those being registered, including any sale under
Rule 144. The foregoing provisions of this Section 4.5(a) shall not apply to offers or sales of Registrable Securities that are included
in an offering pursuant to Section 4.1, Section 4.2 or Section 4.4 of this Agreement and shall be applicable to the Stockholders only
if, for so long as and to the extent that the Company, the directors and executive officers of the Company, and each selling stockholder
included in such offering are subject to the same restrictions if requested by the managing underwriter(s) for such offering, and the
Company uses its reasonable best efforts to ensure that each other holder of at least 5% of the outstanding shares of Common Stock is
subject to the same restrictions if requested by the managing underwriter(s) for such offering. Each Stockholder 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 4.5(a) and are necessary to give further effect thereto. Any discretionary waiver or termination of the requirements under
the foregoing

 

    

     

    

provisions
made by the Company or the applicable managing underwriter(s) shall apply to each Stockholder that holds or Beneficially Owns Registrable
Securities proposed to be sold in such offering on a pro rata basis. Without limiting the foregoing, if after the date hereof the Company
grants any Person (other than a Stockholder) any rights to demand or participate in a registration, the Company agrees that it shall
include in such Person’s agreement a covenant consistent with the foregoing provisions of this Section 4.5(a).

 

(b)    
The Company. To the extent 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 for its own account during the
period commencing seven (7) days prior to and ending sixty (60) days after the pricing of an underwritten offering pursuant to Section
4.1, Section 4.2, or Section 4.4 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 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.

 

Section
4.6    
Suspensions. Up to two (2) times in any twelve (12) month period, and for no more than ninety (90) days in the aggregate,
upon giving prompt written notice to the Scott Family Stockholders, the Company shall be entitled to delay or suspend the filing,
effectiveness or use of a Registration Statement or Prospectus (a “Suspension”) if the Company determines in good faith
that proceeding with the filing, effectiveness or use of such Registration Statement or Prospectus would require the Company to publicly
disclose material non-public information in such Registration Statement or Prospectus so that it would not be materially misleading, the
disclosure of which (i) would not be required to be made at such time but for the filing, effectiveness or use of such Registration Statement
or Prospectus and (ii) would, in the good faith judgment of the Company, have a material adverse effect on the Company or on any pending
negotiation or plan of the Company to effect a merger, acquisition, disposition, financing, reorganization, recapitalization or other
similar transaction. Each Scott Family Stockholder who is notified by the Company of a Suspension pursuant to this Section 4.6
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 Stockholder to immediately discontinue) offers and sales of Registrable Securities
pursuant to such Registration Statement or Prospectus and any other use of such Registration Statement or Prospectus until 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 4.7(g). If the Company delays or suspends
a Demand Registration, the Initiating Holder of 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 limitation on the number of such Initiating Holder’s
Demand Registrations set forth in Section 4.2(b). The Company shall promptly notify the Scott Family Stockholders of the expiration
of any period during which it exercised its rights under this Section. The Company agrees that, in the event it exercises its rights under
this Section, it shall, within sixty (60) days following the Stockholders’ receipt of the notice of suspension, update the suspended
Registration Statement as

 

    

     

    

may
be necessary to permit the Scott Family Stockholders to resume use thereof in connection with the offer and sale of their Registrable
Securities in accordance with applicable law.

 

Section
4.7    
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 best 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 practicable and, pursuant thereto,
the Company shall as expeditiously as possible and as applicable:

 

(a)    
prepare and file with the SEC a Registration Statement with respect to such Registrable Securities, make all required filings
required in connection therewith and (if the Registration Statement is not automatically effective upon filing) use its reasonable best
efforts to cause such Registration Statement to become effective as promptly as practicable;

 

(b)    
prepare and file with the SEC such amendments and supplements to any Registration Statement and the Prospectus used in connection
therewith as may be (i) reasonably requested by any selling Scott Family Stockholder (to the extent such request relates to information
relating to such Scott Family Stockholder), or (ii) necessary to keep such Registration Statement effective until all of the Registrable
Securities covered by such Registration Statement have been disposed of and comply with the applicable requirements of the Securities
Act with respect to the disposition of the Registrable Securities covered by such Registration Statement;

 

(c)    
before filing a Registration Statement or Prospectus, or any amendments or supplements thereto and in connection therewith,
furnish to the managing underwriter or underwriters, if any, and to each Scott Family Stockholder participating in the registration, without
charge, such number of copies of the Prospectus included in such Registration Statement (including each preliminary Prospectus) and any
supplement thereto (in each case including all exhibits thereto and all documents incorporated by reference therein) and such other documents
as such Stockholder may reasonably request, including in order to facilitate the disposition of the Registrable Securities owned by such
Scott Family Stockholder, which documents will be subject to the review of such underwriters and such Stockholders and their respective
counsel, and not file any Registration Statement or Prospectus or amendments or supplements thereto to which the Scott Family Stockholders
covered by the same or the underwriter or underwriters, if any, shall reasonably object;

 

(d)    
use its reasonable best efforts to register or qualify such Registrable Securities under such other securities or blue sky
Laws of such U.S. jurisdiction(s) as any Scott Family Stockholder participating in the registration or any managing underwriter reasonably
requests and do any and all other acts and things that may be necessary or reasonably advisable to enable such Stockholder and each underwriter,
if any, to consummate the disposition of such Scott Family Stockholder’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 or subject itself 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 4.7(d);

 

(e)    
use its reasonable best efforts to cause all Registrable Securities covered by any Registration Statement to be registered
with or approved by such other Governmental Entities

 

    

     

    

or
self-regulatory bodies as may be necessary or reasonably advisable in light of the business and operations of the Company to enable each
Scott Family Stockholder participating in the registration to consummate the disposition of such Registrable Securities in accordance
with the intended method or methods of disposition thereof; provided, that the Company shall not be required to qualify generally
to do business, subject itself to taxation or consent or subject itself 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 4.7(e);

 

(f)     
promptly notify each Scott Family Stockholder participating in the registration and the managing underwriters of any underwritten
offering:

 

(i)    
each time when the Registration Statement, any pre-effective amendment thereto, the Prospectus or any Prospectus supplement
or any post-effective amendment to the Registration Statement has been filed and, with respect to the Registration Statement or any post-effective
amendment thereto, when the same has become effective;

 

(ii)    
of any oral or written comments by the SEC or of any request by the SEC or any other federal or state governmental authority
for amendments or supplements to the Registration Statement or the Prospectus or for any additional information regarding such Stockholder;

 

(iii)    
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

 

(iv)     
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;

 

(g)    
notify each Scott Family Stockholder participating in such registration, at any time when a Prospectus relating thereto
is required to be delivered under the Securities Act, upon becoming aware 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 Stockholder 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;

 

(h)    
in the event of the issuance of any stop order suspending the effectiveness of a Registration Statement, any order suspending
or preventing the use of any related Prospectus or any suspension of the qualification or exemption from qualification of any Registrable
Securities for sale in any jurisdiction, use its best efforts to promptly obtain the withdrawal or lifting of any such order or suspension;

 

    

     

    

(i)    
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 Scott Family Stockholder covered thereby by name or
otherwise identifies such Scott Family Stockholder as the holder of any securities of the Company without the consent of such Scott Family
Stockholder (such consent not to be unreasonably withheld or delayed), unless and to the extent such disclosure is required by Law; provided,
that (i) each Stockholder 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 (ii) each Scott Family Stockholder
agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished to the Company
by such Scott Family Stockholder (including with respect to any inaccuracy in any representations or warranties made by such Stockholder
in any underwriting agreement) or of the occurrence of any event that would cause the Registration Statement or the Prospectus included
in such Registration Statement to contain an untrue statement of a material fact regarding such Stockholder or the distribution of such
Registrable Securities or to omit to state any material fact regarding such Scott Family Stockholder or the distribution of such Registrable
Securities required to be stated therein or necessary to make the statements made therein not misleading in 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 Stockholder such that such Registration Statement and Prospectus shall not contain
any untrue statement of a material fact regarding such Scott Family Stockholder or the distribution of such Registrable Securities or
omit to state a material fact regarding such Scott Family Stockholder 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;

 

(j)    
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 reasonable best efforts to cause such Registrable Securities
to be listed on a national securities exchange selected by the Company after consultation with the Stockholders participating in such
registration;

 

(k)    
provide a transfer agent and registrar (which may be the same entity) for all such Registrable Securities not later than

financial and other records relating to the Company and its business reasonably requested by such Scott Family Stockholder or underwriter,
cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by
any such Scott Family Stockholder, 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;
provided, that any Person gaining access to information or personnel of the Company pursuant to this Section 4.7(l) shall (i) reasonably
cooperate with the Company to limit

 

    

     

    

any
resulting disruption to the Company’s business and (ii) protect the confidentiality of any information regarding the Company which
the Company determines in good faith to be confidential and of which determination such Person is notified, pursuant to customary confidentiality
agreements reasonably acceptable to the Company;

 

(m)     
otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the SEC, and make available
to its stockholders, 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 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, promptly incorporate in a supplement to the Prospectus

or any Scott Family Stockholder participating in such underwritten offering to be included therein, the purchase price for the securities
to be paid by the underwriters and any other applicable terms of such underwritten offering (and the Scott Family Stockholders shall promptly
supply any such information within their possession), and promptly make all required filings of such supplement or post-effective amendment;

 

(o)    
in the case of an underwritten offering of Registrable Securities, enter into such customary agreements (including underwriting
and lock-up agreements in customary form) and take all such other customary actions as any Scott Family Stockholder 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;

 

(p)    
in the case of an underwritten offering of Registrable Securities, furnish to each underwriter, if any, participating in
an offering of Registrable Securities (i) (A) all legal opinions of outside counsel to the Company required to be included in the Registration
Statement and (B) a written legal opinion of outside counsel to the Company, dated the closing date of the offering, in form and substance
as is customarily given in opinions of outside counsel to the Company to underwriters in underwritten registered offerings; and (ii) (A)
obtain all consents of independent public accountants required to be included in the Registration Statement and (B) on the date of the
execution of the applicable underwriting agreement and at the closing of the offering, dated the respective dates of delivery thereof,
a “comfort letter” signed by the Company’s independent public accountants in form and substance as is customarily given
in accountants’ letters to underwriters in underwritten registered offerings;

 

(q)    
in the case of an underwritten offering of Registrable Securities, make senior management of the Company available, to the
extent requested by the managing underwriter(s), to assist in the marketing of the Registrable Securities to be sold in such underwritten
offering, including the participation of such members of senior management of the Company in “road show” presentations and
other customary marketing activities, including “one-

 

    

     

    

on-one”
meetings with prospective purchasers of the Registrable Securities to be sold in such underwritten offering (with an understanding that
these shall be scheduled in a collaborative manner so as not to unreasonably interfere with the conduct of business of the Company),
and otherwise facilitate, cooperate with, and participate in such underwritten offering and customary selling efforts related thereto,
in each case to the same extent as if the Company were engaged in a primary underwritten registered offering of its Common Stock;

 

(r)     
cooperate with the Scott Family Stockholders 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 representing such number
of shares of Common Stock and registered in such names as the Scott Family Stockholders may reasonably request a reasonable period of
time prior to sales of Registrable Securities pursuant to such Registration Statement; provided, that the Company may satisfy its
obligations hereunder without issuing physical stock certificates through the use of The Depository Trust Company’s Direct Registration
System;

 

(s)     
not later than the effective date of such Registration Statement, provide a CUSIP number for all Registrable Securities
covered thereby and provide the applicable transfer agent with printed certificates for the Registrable Securities in a form eligible
for deposit with The Depository Trust Company; provided, that the Company may satisfy its obligations hereunder without issuing
physical stock certificates through the use of The Depository Trust Company’s Direct Registration System;

 

(t)    
upon the request of any Scott Family Stockholder, promptly amend any Shelf Registration Statement or take such other action
as may be necessary to de-register, remove or withdraw all or a portion of such Scott Family Stockholder’s shares of Common Stock
from a Shelf Registration Statement, as requested by such Stockholder; and

 

(u)    
otherwise use its reasonable best efforts to take or cause to be taken all other actions necessary or reasonably advisable
to effect the registration, marketing and sale of such Registrable Securities contemplated by this Agreement.

 

(v)    
Each Stockholder agrees that upon receipt of any notice from the Company of the happening of any event of the kind described
in Section 4.7(g) or Section 4.7(h), such Stockholder shall use its best efforts to discontinue (and direct any other Person making offers
or sales of Registrable Securities on behalf of such Stockholder to discontinue) offers and sales of Registrable Securities pursuant to
such Registration Statement or Prospectus and any other use of such Registration Statement or Prospectus until such time as it is advised
in writing by the Company that the use of the Registration Statement or Prospectus may be resumed. If the Company gives any such notice
in respect of a Demand Registration, the Initiating Holder shall be entitled to withdraw its Demand Registration Request and, if it does
so, such Demand Registration Request shall not count against the limitation on the number of such Initiating Holder’s Demand Registrations
set forth in Section 4.2(b).

 

Section
4.8    
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 (which shall contain such terms and conditions as are generally
prevailing in agreements of that type, including indemnities no more burdensome to the indemnifying party and no less favorable to the
recipient thereof than those provided in Section 4.10 hereof) 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 Scott Family Stockholder that holds or Beneficially Owns any Registrable Securities included in any underwritten offering hereunder
shall be required to make any representations or warranties to the Company or the underwriters (other than representations and warranties
regarding (A) such Scott Family Stockholder’s identity and ownership of its Registrable Securities to be sold in such offering,
(B) such Scott Family Stockholder’s power and authority to effect such transfer, (C) such Scott Family Stockholder’s intended
method of disposition, (D) information furnished by such Scott Family Stockholder expressly for inclusion in any Registration Statement
or Prospectus, and (E) such matters pertaining to such Scott Family Stockholder’s compliance with securities Laws 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, other than indemnities that are no more burdensome to the indemnifying party and no less favorable to the recipient thereof
than those provided in Section 4.10 hereof.

 

Section
4.9    
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 in connection with the registration of Registrable Securities,
including, without limitation, (i) all SEC, FINRA 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
reasonable fees and disbursements of one counsel in connection therewith); (iv) all printing, messenger, telephone and delivery 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 fees; (vii) all fees and expenses of counsel to the Company and up to $50,000 of

retained by the Company (for the avoidance of doubt, excluding underwriters) in connection with or incident to any registration of Registrable
Securities pursuant to this Agreement (all such costs, fees and expenses, “Registration Expenses”). Each Scott Family
Stockholder shall bear its respective Selling Expenses associated with a registered sale of its Registrable Securities pursuant to this
Agreement. For the avoidance of doubt, neither Registration Expenses nor Selling Expenses shall include the fees or expenses of any underwriters’
counsel.

 

(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 at the request of one or more Scott Family Stockholder(s)

 

    

     

    

(unless
withdrawn following commencement of a Suspension) shall be borne by such Scott Family Stockholder(s).

 

Section
4.10     Indemnification;
Contribution.

 

(a)    
The Company shall, to the fullest extent permitted by Law, indemnify and hold harmless each Scott Family Stockholder, any
Person who is a “controlling person” of such Stockholder or any of its subsidiaries 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, advisory board members, directors, officers, trustees, managers, members, employees, agents,
Affiliates and shareholders, and each other agent, if any, who acts on behalf of or controls any such Stockholder or Controlling Person
(each of the foregoing, a “Covered Person”) against any losses, claims, actions, damages, liabilities (or actions or
proceedings in respect thereof, whether or not such Covered Person is a party thereto) and expenses (including reasonable costs of investigation
and legal 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) (a “Free Writing Prospectus”) or any amendment thereof or supplement
thereto or any document incorporated by reference therein or (ii) any omission or alleged omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading, 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 or any 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 or arises out of or based
upon such Covered Person’s failure to deliver a copy of the Prospectus or any amendments or supplements thereto to a purchaser (if
so required) after the Company has furnished such Covered Person with a sufficient number of copies of the same. This indemnity shall
be in addition to any liability the Company may otherwise have.

 

(b)    
In connection with any registration in which a Stockholder is participating, each such Stockholder shall (severally and
not jointly), to the fullest extent permitted by Law, indemnify and hold harmless the Company, any Person who is a Controlling Person
of the Company, their respective direct and indirect general and limited partners, advisory board members, directors, officers, trustees,
managers, members, employees, agents, Affiliates and shareholders, and each other agent, if any, who acts on behalf of or controls the
Company or Controlling Person (each of the foregoing, a “Company Covered Person”) against any losses, claims, actions,
damages, liabilities (or actions or proceedings in respect thereof, whether or not such Company Covered Person is a party thereto) and
expenses (including reasonable costs of

 

    

     

    

investigation
and legal 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 or any amendment thereof or supplement thereto or
any document incorporated by reference therein or (ii) any omission or alleged omission of a material fact required to be stated therein
or necessary to make the statements therein not misleading, but, in the case of each of clauses (i) and (ii) solely 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 or any amendment thereof or supplement thereto or any document incorporated by reference
therein in reliance upon, and in conformity with, written information regarding such Stockholder prepared and furnished to the Company
by such Stockholder expressly for use therein; provided, that the obligation to indemnify pursuant to this Section 4.10(b) shall
be individual and several, not joint and several, for each participating Stockholder and shall not exceed an amount equal to the net
proceeds (after deducting its portion of Selling Expenses) actually received by such Stockholder in the sale of Registrable Securities
to which such Registration Statement or Prospectus relates; provided, further, that notwithstanding anything in this Agreement
to the contrary, in no event shall the Stockholders or any other Covered Person be deemed a Company Covered Person. This indemnity shall
be in addition to any liability which such Stockholder 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, 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)
in the reasonable judgment of any such indemnified party, based upon advice of its counsel, a conflict of interest exists or may potentially
exist between such indemnified party and the indemnifying party with respect to such claims or (E) the indemnified party has reasonably
concluded 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 proviso in the foregoing sentence, no indemnifying
party shall,

 

    

     

    

in connection with any one claim
or action or separate but substantially similar or related actions arising out of the same general circumstances or allegations, be liable
for the fees, costs and expenses of more than one 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 (not to be unreasonably withheld, conditioned or delayed), 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
in either case such judgment or settlement does not impose any admission of wrongdoing or injunctive or equitable relief binding on any
indemnified party and includes as an unconditional term thereof the giving by the claimant or plaintiff therein 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 4.10 is held by a court of competent jurisdiction to be unavailable
to, or unenforceable by, or is for any reason insufficient to hold harmless as contemplated by this Section 4.10 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 or omissions which resulted
in such loss, claim, action, damage, liability or expense as well as any other relevant equitable considerations. The 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, and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or omission. 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 4.10(d). In no event shall the amount which a Stockholder may be
obligated to contribute pursuant to this Section 4.10(d) exceed an amount by which the net proceeds (after deducting its portion of Selling
Expenses) actually received by such Stockholder in the sale of Registrable Securities that gives rise to such obligation to contribute
exceeds the amount of any damages which such indemnifying party has otherwise been required to pay by reason of such untrue statement
or omission. 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 4.10 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 Stockholder.

 

    

     

    

Section
4.11     Rule
144 Compliance. With a view to making available to the Stockholders of Registrable Securities the benefits of Rule 144 and any other
rule or regulation of the SEC that may at any time permit a Scott Family Stockholder to sell securities of the Company to the public
without registration, the Company shall:

 

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

 

(b)    
use reasonable best 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;

 

(c)    
furnish to any Stockholder, 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;

 

(d)    
take such further action as any Scott Family Stockholder may reasonably request, to the extent required from time to time
to enable such Scott Family Stockholder to sell Registrable Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144 or 144A or Regulations S under the Securities Act, as such Rules may be amended from time to time,
or any similar rule or regulation hereafter adopted by the SEC.

 

Section
4.12     Scott
Family Stockholders. As a condition to participating in any registration pursuant to this Article IV, any Scott Family Stockholder
that is not already party to this Agreement (or has not already executed and delivered a joinder to this Agreement) shall be required
to agree in writing to be bound by this Agreement and the Voting Agreement (if then in effect), which such joinder shall be substantially
in the form of Exhibit B attached hereto. For purposes of furnishing notices under this Article IV to Scott Family Stockholders
who are not already party to this Agreement (or have not already executed and delivered a joinder to this Agreement), the Company shall
only be obligated to notify such Scott Family Stockholders, if any, for whom the Stockholders have provided names and addresses to the
Company in advance of such notice period.

Section
5.3    
Enforcement. The Parties agree that irreparable damage would occur and that the Parties would not have any adequate
remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or
were otherwise breached by the other Party. It is accordingly agreed that each of the Parties will be entitled to an injunction or injunctions
to prevent breaches and/or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement,
in each case without the necessity of providing any bond or other security, in any federal court located in the State of Delaware or in
Delaware state court, this being in addition to any other remedy to which they are entitled at law or in equity.

 

Section
5.4    
Entire Agreement; No Third Party Beneficiaries. This Agreement constitutes the entire agreement among the Parties
with respect to the subject matter hereof and supersedes all prior agreements and understandings, both written and oral, between the Parties
with respect to the subject matter hereof. This Agreement will be binding upon and inure solely to the benefit of each Party and its successors
and permitted assigns. Except as set forth in the immediately preceding sentence, nothing in this Agreement, express or implied, is intended
to or will confer upon any Person that is not a Party any rights, benefits or remedies hereunder; provided, however, that (a) the Scott
Family Stockholders shall be express third party beneficiaries of and shall be entitled to directly enforce Article IV (subject to the
requirement under Section 4.12 for a Scott Family Stockholder to be party to, or execute and deliver a joinder to, this Agreement in order
to participate in any registration pursuant to Article IV) and (b) prior to the Effective Time, GWB shall be an express third party beneficiary
of and shall be entitled to directly enforce Section 5.5.  Nothing in this Agreement shall, or shall be construed or deemed
to, constitute a transfer of any Equity Securities or any legal or beneficial interest in or voting or other control over any Equity Securities
or as creating or forming a “group” for purposes of the Exchange Act, and all rights, ownership and benefits of and relating
to the Equity Securities shall remain vested in and belong to each Stockholder, subject to the agreements of the parties set forth herein.  

 

Section
5.5    
Amendments; Waiver. No provision of this Agreement may be amended or waived unless (a) in the case of any amendment
or waiver prior to the Effective Time, GWB has provided its prior written consent thereto and (b) such amendment or waiver is in writing
and signed, in the case of an amendment, by the Parties, or in the case of a waiver, by the Party or Parties against whom the waiver is
to be effective. 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. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by applicable
Law. Except to the extent otherwise provided herein with respect to the exercise of rights of a Stockholder pursuant to Article IV, any
action to be taken by the Stockholders under this Agreement, or any amendment or waiver of this Agreement by the Stockholders, may be
taken by one or more Stockholders holding two-thirds of the Equity Securities then held by all the Stockholders.

 

    

     

    

Section
5.6    
Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned,
in whole or in part, by any Party without the prior written consent of the other Parties; provided, however, that any Scott Family Stockholder
shall be entitled to transfer Equity Securities of the Company to any other Scott Family Stockholder and, in connection therewith, assign
the rights, interests and obligations applicable to a Scott Family Stockholder under this Agreement to any such transferee. Any assignment
in violation of the preceding sentence will be void. Subject to the preceding two sentences, this Agreement will be binding upon, inure
to the benefit of, and be enforceable by, the Parties and their respective successors and assigns. This Section 5.6 shall not be deemed
to prevent the Company from engaging in any merger, consolidation or other business combination transaction. For the avoidance of doubt,
no transferee of Equity Securities of the Company who is not a Scott Family Stockholder shall acquire any rights under, or be deemed to
have the benefit of, any of the provisions contained in this Agreement. If the Company or any of its successors or assigns (i) consolidates
with or merges into any other Person and is not the continuing or surviving entity of such consolidation or merger or (ii) engages in
any transaction as a result of which the Company or any of its successors or assigns is not the publicly traded parent company of the
corporate group that includes the Company or any of its successors or assigns, then in each such case, the Company will cause proper provision
to be made so that the successors and assigns of the Company, or the publicly traded parent company of the corporate group that includes
the Company or any of its successors or assigns, will expressly assume the obligations of the Company set forth in this Agreement.

 

Section
5.7    
Governing Law. This Agreement and any claim, controversy or dispute arising under or related thereto, the relationship
of the Parties, and/or the interpretation and enforcement of the rights and duties of the Parties, whether arising at law or in equity,
in contract, tort or otherwise, will be governed by, and construed and interpreted in accordance with, the laws of the State of Delaware,
without regard to its rules regarding conflicts of law to the extent that the application of the laws of another jurisdiction would be
required thereby.

 

Section
5.8    
Expenses. If and only if the Merger is consummated in accordance with the terms of the Merger Agreement, as the same
may be amended from time to time, then, at the Closing and following the Effective Time, the Company shall pay or cause to be paid to
the Stockholders all reasonable and documented out-of-pocket expenses incurred by the Stockholders in connection with therewith, up to
a maximum of $8,500,000.

 

Section
5.9    
Interpretation. Unless otherwise expressly provided, for the purposes of this Agreement, the following rules of interpretation
shall apply:

 

(a)    
The article and section headings contained in this Agreement are for convenience of reference only and will not affect in
any way the meaning or interpretation hereof.

 

(b)    
When a reference is made in this Agreement to an article or a section, paragraph, such reference will be to an article or
a section, paragraph hereof unless otherwise clearly indicated to the contrary.

 

    

     

    

(c)    
Unless it would be duplicative, whenever the words “include,” “includes” or “including”
are used in this Agreement, they will be deemed to be followed by the words “without limitation.”

 

(d)    
The words “hereof,” “herein” and “herewith” and words of similar import will, unless
otherwise stated, be construed to refer to this Agreement as a whole and not to any particular provision of this Agreement.

 

(e)    
The word “extent” in the phrase “to the extent” will mean the degree to which a subject or other
thing extends, and such phrase will not mean simply “if.”

 

(f)     
The meaning assigned to each term defined herein will be equally applicable to both the singular and the plural forms of
such term, and words denoting any gender will include all genders. Where a word or phrase is defined herein, each of its other grammatical
forms will have a corresponding meaning.

 

(g)    
A reference to any period of days will be deemed to be to the relevant number of calendar days, unless otherwise specified.

 

(h)    
All terms defined in this Agreement will have the defined meanings when used in any certificate or other document made or
delivered pursuant hereto unless otherwise defined therein.

 

(i)    
A holder of any Voting Securities held in trust shall be deemed to be the relevant trust and/or trustee thereof acting in
his or her capacities as such trustees, in each case as the context may require to be most protective of the Company, including for purposes
of such trustee’s representations and warranties as to the proper organization of the trust, their power and authority as trustees
and the non-contravention of the trust’s governing documents.

 

(j)    
The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question
of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the Parties, and no presumption or burden
of proof will arise favoring or disfavoring any Party by virtue of the authorship of any provisions hereof.

 

(k)    
Any statute or rule defined or referred to herein or in any agreement or instrument that is referred to herein means such
statute or rule as from time to time amended, modified or supplemented, including by succession of comparable successor statutes or rules
and references to all attachments thereto and instruments incorporated therein.

 

Section
5.10     Consent
to Jurisdiction. Each of the Parties agrees that any legal action or proceeding with respect to this Agreement, or for recognition
and enforcement of any judgment in respect of this Agreement and obligations arising hereunder brought by any other Party or its successors
or assigns, will be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within
the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal
court within the State of Delaware). Each of the Parties hereby irrevocably submits with regard to any such action or proceeding for itself
and in respect of its property, generally and unconditionally,

 

    

     

    

to
the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement in any court
other than the aforesaid courts. Each of the Parties hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense,
counterclaim or otherwise, in any action or proceeding with respect to this Agreement (a) any claim that it is not personally subject
to the jurisdiction of the above-named courts for any reason other than the failure to serve in accordance with this Section 5.10, (b)
any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such
courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment
or otherwise), and (c) to the fullest extent permitted by the applicable law, any claim that (i) the suit, action or proceeding in such
court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper, or (iii) this Agreement or
the subject matter hereof, may not be enforced in or by such courts.

 

Section
5.11     Waiver
of Jury Trial. EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
(WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY OR THE
ACTIONS OF ANY OF THE PARTIES IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.

 

Section
5.12     Severability.
If any term or other provision of this Agreement is held to be invalid, illegal or incapable of being enforced by any rule of law or public
policy by a court of competent jurisdiction, all other conditions and provisions of this Agreement will nevertheless remain in full force
and effect, insofar as the foregoing can be accomplished without materially affecting the economic benefits anticipated by the Parties.
Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties will negotiate
in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible to the fullest extent
permitted by applicable law in an acceptable manner to the end that the transactions contemplated by this Agreement are fulfilled to the
extent possible.

 

Section
5.13     Headings.
The descriptive headings contained in this Agreement are for reference purposes only and will not affect in any way the meaning or interpretation
of this Agreement.

 

Section
5.14     Counterparts.
This Agreement may be executed in two or more counterparts, each of which when executed will be deemed to be an original, and all of which
together will be considered one and the same agreement and will become effective when one or more counterparts have been signed by each
of the Parties and delivered to the other Parties. For purposes of this Agreement, facsimile signatures or signatures by other electronic
form of transfer will be deemed originals, and the Parties agree to exchange original signatures as promptly as possible.

Gentlemen:

 

Reference is made to the Stockholders’

in accordance with its terms, the “Stockholders’ Agreement”), by and between the Stockholders (as defined in
the Stockholders’ Agreement) party thereto and First Interstate BancSystem, Inc., a Montana corporation (the “Company”).  Pursuant
to the Agreement, among other things, each of the Stockholders that holds Common Stock is required to enter into this Voting Agreement

Stockholders’ Agreement).  Defined terms used but not otherwise defined herein shall have the meanings ascribed thereto
in the Stockholders’ Agreement.

 

Accordingly, with respect
to any vote or consent in respect of the election of any candidate nominated by the Board for election or appointment as a Director (other
than to the extent relating to the election or appointment of a Stockholder Nominee), but only if the Stockholders have designated one
or more Stockholder Nominees who are then serving on the Board or have designated one or more Stockholder Nominees for election as a director
at the applicable meeting pursuant to this Agreement, Stockholder shall (a) in the case of any vote, cause all shares of Common Stock
that it Beneficially Owns (and which are entitled to vote on the election of Directors) to be counted as present for purposes of calculating
a quorum and (b) vote, or cause to be voted, or execute written consents with respect to, all shares of Common Stock that it Beneficially
Owns (and which are entitled to vote on such matter) at its election either (i) in accordance with the recommendation of the Board as
to the election of Directors or (ii) in the same proportions as the votes cast on the election of Directors in respect of all shares of
Common Stock not Beneficially Owned by such Stockholder; provided that such Stockholder shall only be required to vote, or cause to be
voted, or execute written consents, pursuant to this clause (b) to the extent such matter is not inconsistent with any provision of the
Stockholders’ Agreement.

 

This Voting Agreement and
any claim, controversy or dispute arising under or related to this Voting Agreement shall be governed by, and construed in accordance
with the laws of, the State of Delaware without regard to its choice of law provisions.
