The
purpose of the ECO-STIM ENERGY SOLUTIONS, INC. 2015 STOCK INCENTIVE PLAN (as it may be amended, restated or otherwise modified
from time to time, the “Plan”) is to provide a means through which ECO-STIM ENERGY SOLUTIONS, INC.,
a Nevada corporation (the “Company”), and its Affiliates may attract and retain able persons to serve
as Directors or Consultants or to enter the employ of the Company and its Affiliates and to provide a means whereby those individuals
upon whom the responsibilities of the successful administration and management of the Company and its Affiliates rest, and whose
present and potential contributions to the Company and its Affiliates are of importance, can acquire and maintain stock ownership
or other awards, thereby strengthening their concern for the welfare of the Company and its Affiliates and their desire to remain
employed by, or continue providing services to, the Company and its Affiliates. A further purpose of the Plan is to provide such
individuals with additional incentive and reward opportunities designed to enhance the profitable growth of the Company and its
Affiliates. Accordingly, the Plan provides for granting Incentive Stock Options, Options that do not constitute Incentive Stock
Options, Restricted Stock Awards, Performance Awards, Phantom Stock Awards, Bonus Stock Awards, or any combination of the foregoing,
as is best suited to the circumstances of the particular employee, Director or Consultant as provided herein.


 


The
Plan as set forth herein constitutes an amendment and restatement of the Eco-Stim Energy Solutions, Inc. 2014 Stock Incentive
Plan (the “Prior Plan”). Except as provided in the following sentence, the Plan as set forth herein
shall supersede and replace in its entirety the Prior Plan. Notwithstanding any provisions herein to the contrary, each Award
granted under the Prior Plan prior to the Effective Date shall be subject to the terms and provisions applicable to such Award
under the Prior Plan as in effect immediately prior to the Effective Date, except that any such Award that is an Option or a Stock
Appreciation Right shall also be subject to the provisions of Paragraph VII(f) of the Plan as set forth herein.

IV.ADMINISTRATION


 


(a)Composition
of Committee. The Plan shall be administered by a committee of, and appointed by, the Board
that shall be comprised solely of two or more Directors who are both (i) outside Directors (within the meaning of section 162(m)
of the Code and applicable interpretive authority thereunder) and (ii) non-employee Directors (within the meaning of Rule 16b-3).
In the absence of the Board’s appointment of a committee to administer the Plan, the Board shall serve as the Committee.


 


(b)Powers.
Subject to the express provisions of the Plan, the Committee shall have authority, in its discretion, to determine which employees,
Consultants or Directors shall receive an Award, the time or times when such Award shall be made, the type of Award that shall
be made, the number of shares of Common Stock to be subject to each Option, Restricted Stock Award, or Bonus Stock Award, and
the number of shares of Common Stock to be subject to or the value of each Performance Award or Phantom Stock Award. In making
such determinations, the Committee shall take into account the nature of the services rendered by the respective employees, Consultants
or Directors, their present and potential contribution to the Company’s success, and such other factors as the Committee
in its sole discretion shall deem relevant.


 


(c)Additional
Powers. The Committee shall have such additional powers as are delegated to it by the other provisions of the Plan. Subject
to the express provisions of the Plan, this shall include the power to construe the Plan and the respective agreements executed
hereunder, to prescribe, amend, suspend or waive rules and regulations relating to the Plan, to determine the terms, restrictions,
and provisions of the agreement relating to each Award, including such terms, restrictions, and provisions as shall be requisite
in the judgment of the Committee to cause designated Options to qualify as Incentive Stock Options, and to make all other determinations
necessary or advisable for administering the Plan. The Committee may correct any defect or supply any omission or reconcile any
inconsistency in the Plan or in any agreement relating to an Award in the manner and to the extent the Committee shall deem expedient
to carry the Plan or any such agreement into effect. All determinations and decisions made by the Committee on the matters referred
to in this Paragraph IV and in construing the provisions of the Plan shall be conclusive.


 


(d)Delegation
of Authority by the Committee. Notwithstanding the preceding provisions of this Paragraph IV or any other provision of
the Plan to the contrary, subject to the constraints of applicable law, the Committee may from time to time, in its sole discretion,
delegate to the Chief Executive Officer of the Company the administration (or interpretation of any provision) of the Plan, and
the right to grant Awards under the Plan, insofar as such administration (and interpretation) and power to grant Awards relates
to any person who is not then subject to section 16 of the Exchange Act (including any successor section to the same or similar
effect). Any such delegation may be effective only so long as the Chief Executive Officer of the Company is a member of the Board,
and the Committee may revoke such delegation at any time in its sole discretion. The Committee may put any conditions and restrictions
on the powers that may be exercised by the Chief Executive Officer of the Company upon such delegation as the Committee determines
in its sole discretion. In the event of any conflict in a determination or interpretation under the Plan as between the Committee
and the Chief Executive Officer of the Company, the determination or interpretation, as applicable, of the Committee shall be
conclusive.

V.SHARES
SUBJECT TO THE PLAN; AWARD LIMITS; GRANT OF AWARDS


 


(a)Shares
Subject to the Plan and Award Limits. Subject to adjustment in the same manner as provided in Paragraph XII with respect
to shares of Common Stock subject to Options then outstanding, the aggregate maximum number of shares of Common Stock that may
be issued under the Plan, and the aggregate maximum number of shares of Common Stock that may be issued under the Plan through
Incentive Stock Options, shall not exceed 1,000,000 shares (which number includes the 500,000 shares
of Common Stock originally available for issuance pursuant to the Prior Plan, including shares of Common Stock previously issued
pursuant to an Award (or made subject to an Award that has not expired or been terminated) granted under the Prior Plan prior
to the Effective Date), as well as an additional 500,000 shares of Common Stock first being made available for issuance under
the Plan in connection with this amendment and restatement of the Plan). Shares shall be deemed to have been issued under
the Plan only to the extent actually issued and delivered pursuant to an Award. To the extent that an Award lapses or the rights
of its holder terminate, any shares of Common Stock subject to such Award shall again be available for the grant of an Award under
the Plan. In addition, shares issued under the Plan and forfeited back to the Plan, shares surrendered in payment of the exercise
price or purchase price of an Award, and shares withheld for payment of applicable employment taxes and/or withholding obligations
associated with an Award shall again be available for the grant of an Award under the Plan. Notwithstanding any provision in the
Plan to the contrary, (i) the maximum number of shares of Common Stock that may be subject to Awards denominated in shares of
Common Stock granted under the Plan to any one individual during any 12-month period may not exceed 200,000 shares (subject to
adjustment from time to time in accordance with the provisions of the Plan) and (ii) the maximum amount of compensation that may
be paid under all Performance Awards that are not denominated in shares of Common Stock (including the Fair Market Value of any
shares of Common Stock paid in satisfaction of such Performance Awards) granted to any one individual during any 12-month period
may not exceed $1,000,000, and any payment due with respect to a Performance Award shall be paid no later than 10 years after
the date of grant of such Performance Award. The limitations set forth in the preceding sentence shall be applied in a manner
that will permit Awards that are intended to provide “performance-based” compensation for purposes of section 162(m)
of the Code to satisfy the requirements of such section, including, without limitation, counting against such maximum number of
shares, to the extent required under section 162(m) of the Code and applicable interpretive authority thereunder, any shares subject
to Awards granted to employees that are canceled or repriced. In addition, and notwithstanding any provision herein to the contrary,
the aggregate grant date fair value (computed as of the date of grant in accordance with applicable financial accounting rules)
of all Awards granted to any individual, non-employee Director during any single calendar year beginning on or after January 1,
2015 shall not exceed $500,000; provided, however, that such limitation shall be (x) $600,000 in the first year an individual
becomes a non-employee Director and (y) determined without regard to grants of Awards, if any, made to a non-employee Director
during any period in which such individual was an employee or Consultant.


 




    	 	6	 



     

    

  


(b)Grant
of Awards. The Committee may from time to time grant Awards to one or more employees, Consultants,
or Directors determined by it to be eligible for participation in the Plan in accordance with the terms of the Plan. For
the avoidance of doubt, the Committee shall have the exclusive authority and sole discretion to determine the types of Awards
granted to such employees, Consultants, or Directors and in no event shall such employees,
Consultants, or Directors be permitted at any time to elect the types of Awards granted to them under the Plan.


 


(c)Stock
Offered. Subject to the limitations set forth in Paragraph V(a), the stock to be offered pursuant to the grant of an Award
may be authorized but unissued Common Stock or Common Stock previously issued and outstanding and reacquired by the Company. Any
of such shares that remain unissued and that are not subject to outstanding Awards at the termination of the Plan shall cease
to be subject to the Plan but, until termination of the Plan, the Company shall at all times make available a sufficient number
of shares to meet the requirements of the Plan. The shares of the Company’s stock to be issued pursuant to any Award may
be represented by physical stock certificates or may be uncertificated. Notwithstanding references in the Plan to certificates,
the Company may deliver uncertificated shares of Common Stock in connection with any Award.


 


VI.ELIGIBILITY


 


Awards
may be granted only to persons who, at the time of grant, are employees, Consultants, or Directors. An Award may be granted on
more than one occasion to the same person, and, subject to the limitations set forth in the Plan, such Award may include an Incentive
Stock Option, an Option that is not an Incentive Stock Option, a Restricted Stock Award, a Performance Award, a Phantom Stock
Award, a Bonus Stock Award, or any combination thereof.


 


VII.STOCK
OPTIONS


 


(a)Option
Period. The term of each Option shall be as specified by the Committee at the date of grant, but in no event shall an
Option be exercisable after the expiration of 10 years from the date of grant.


 


(b)Limitations
on Exercise of Option. An Option shall be exercisable in whole or in such installments and at such times as determined
by the Committee.


 


(c)Special
Limitations on Incentive Stock Options. An Incentive Stock Option may be granted only to an individual who is employed
by the Company or any “parent corporation” or “subsidiary corporation” (as such terms are defined in section
424 of the Code) of the Company at the time the Option is granted. To the extent that the aggregate fair market value (determined
at the time the respective Incentive Stock Option is granted) of stock with respect to which Incentive Stock Options are exercisable
for the first time by an individual during any calendar year under all incentive stock option plans of the Company and its parent
and subsidiary corporations, within the meaning of section 424 of the Code, exceeds $100,000 or such other amount as may be prescribed
under section 422 of the Code or applicable regulations or rulings from time to time, such Incentive Stock Options shall be treated
as Options that do not constitute Incentive Stock Options. The Committee shall determine, in accordance with applicable provisions
of the Code, Treasury regulations, and other administrative pronouncements, which of a Participant’s Incentive Stock Options
will not constitute Incentive Stock Options because of such limitation and shall notify the Participant of such determination
as soon as practicable after such determination. No Incentive Stock Option shall be granted to an individual if, at the time the
Option is granted, such individual owns stock possessing more than 10% of the total combined voting power of all classes of stock
of the Company or of its parent or subsidiary corporation, within the meaning of section 422(b)(6) of the Code, unless (i) at
the time such Option is granted, the option price is at least 110% of the Fair Market Value of the Common Stock subject to the
Option and (ii) such Option by its terms is not exercisable after the expiration of five years from the date of grant. Except
as otherwise provided in sections 421 or 422 of the Code, an Incentive Stock Option shall not be transferable otherwise than by
will or the laws of descent and distribution and shall be exercisable during the Participant’s lifetime only by such Participant
or the Participant’s guardian or legal representative.


 




    	 	7	 



     

    

  


(d)Option
Agreement. Each Option shall be evidenced by an Option Agreement in such form and containing such provisions not inconsistent
with the provisions of the Plan as the Committee from time to time shall approve, including, without limitation, provisions to
qualify an Option as an Incentive Stock Option under section 422 of the Code. Each Option Agreement shall specify the effect of
termination of (i) employment, (ii) the consulting or advisory relationship, or (iii) membership on the Board or the board of
directors (or analogous governing body) of an Affiliate of the Company, as applicable, on the exercisability of the Option. An
Option Agreement may provide for the payment of the option price, in whole or in part, by the delivery of a number of shares of
Common Stock (plus cash if necessary) having a Fair Market Value equal to such option price. Moreover, an Option Agreement may
provide for a “cashless exercise” of the Option by establishing procedures satisfactory to the Committee with respect
thereto. Further, an Option Agreement may provide, on such terms and conditions as the Committee in its sole discretion may prescribe,
for the grant of a Stock Appreciation Right in connection with the grant of an Option and, in such case, the exercise of the Stock
Appreciation Right shall result in the surrender of the right to purchase a number of shares under the Option equal to the number
of shares with respect to which the Stock Appreciation Right is exercised (and vice versa). In the case of any Stock Appreciation
Right that is granted in connection with an Incentive Stock Option, such right shall be exercisable only when the Fair Market
Value of the Common Stock exceeds the exercise price specified therefor in the Option or the portion thereof to be surrendered.
The terms and conditions of the respective Option Agreements need not be identical. The Committee may, in its sole discretion,
amend an outstanding Option Agreement from time to time in any manner that is not inconsistent with the provisions of the Plan
(including, without limitation, an amendment that accelerates the time at which the Option, or a portion thereof, may be exercisable),
provided that, except as otherwise provided in the Plan or the applicable Option Agreement, any such amendment shall not materially
reduce the rights of a Participant without the consent of such Participant.


 


(e)Option
Price and Payment. The price at which a share of Common Stock may be purchased upon exercise of an Option shall be determined
by the Committee but, subject to the special limitations on Incentive Stock Options set forth in Paragraph VII(c) and to adjustment
as provided in Paragraph XII, such purchase price shall not be less than the Fair Market Value of a share of Common Stock on the
date such Option is granted. The Option or portion thereof may be exercised by delivery of an irrevocable notice of exercise to
the Company, as specified by the Committee. The purchase price of the Option or portion thereof shall be paid in full in the manner
prescribed by the Committee. Separate stock certificates shall be issued by the Company for those shares acquired pursuant to
the exercise of an Incentive Stock Option and for those shares acquired pursuant to the exercise of any Option that does not constitute
an Incentive Stock Option.


 




    	 	8	 



     

    

  


(f)Restrictions
on Repricing of Options or Stock Appreciation Rights. Subject to the provisions of Paragraph XII, the terms of outstanding
Option Agreements may not be amended without the approval of the stockholders of the Company so as to (i) reduce the option price
of any outstanding Options or Stock Appreciation Rights, (ii) grant a new Option, Stock Appreciation Right or other Award in substitution
for, or upon the cancellation of, any previously granted Option or Stock Appreciation Right that has the effect of reducing the
exercise price thereof, (iii) exchange any Option or Stock Appreciation Right for shares of Common Stock, cash or other consideration
when the exercise price per share of Common Stock under such Option or Stock Appreciation Right exceeds the Fair Market Value
of the underlying shares, or (iv) take any other action that would be considered a “repricing” of an Option or Stock
Appreciation Right under the listing standards of the National Association of Securities Dealers, Inc. Automated Quotation System
(“NASDAQ”) or, if the Common Stock is not then-listed on the NASDAQ, to the extent applicable, on any
other national securities exchange on which the Common Stock is listed. Subject to Paragraph XII and the last sentence of Paragraph
VII(d), the Committee shall have the authority, without the approval of the stockholders of the Company, to amend any outstanding
Option Agreement to increase the per share exercise price of any outstanding Options or Stock Appreciation
Rights or to cancel and replace any outstanding Options or Stock Appreciation Rights with the grant of Options or Stock Appreciation
Rights having a per share exercise price that is equal to or greater than the per share exercise price of the original Award.


 


(g)Stockholder
Rights and Privileges. The Participant shall be entitled to all the privileges and rights of a stockholder only with respect
to such shares of Common Stock as have been purchased under the Option and for which shares of stock have been delivered to the
Participant.


 


(h)Options
and Rights in Substitution for Options Granted by Other Employers. Options and Stock Appreciation Rights may be granted
under the Plan from time to time in substitution for options and such rights held by individuals providing services to corporations
or other entities who become employees, Consultants, or Directors as a result of a merger or consolidation or other business transaction
with the Company or any Affiliate.


 


VIII.RESTRICTED
STOCK AWARDS


 


(a)Forfeiture
Restrictions to be Established by the Committee. Shares of Common Stock that are the subject of a Restricted Stock Award
shall be subject to restrictions on transferability by the Participant and an obligation of the Participant to forfeit and surrender
the shares to the Company under certain circumstances (the “Forfeiture Restrictions”). The Forfeiture Restrictions
shall be determined by the Committee in its sole discretion, and the Committee may provide that the Forfeiture Restrictions shall
lapse upon (i) the attainment of one or more Performance Measures, (ii) the Participant’s continued employment with the
Company or one of its Affiliates or continued service as a Consultant or Director for a specified period of time, (iii) the occurrence
of any event or the satisfaction of any other condition specified by the Committee in its sole discretion, or (iv) a combination
of any of the foregoing. Each Restricted Stock Award may have different Forfeiture Restrictions, in the discretion of the Committee.


 




    	 	9	 



     

    

  


(b)Other
Terms and Conditions. Unless provided otherwise in a Restricted Stock Agreement, the Participant shall have the right
to receive dividends with respect to Common Stock subject to a Restricted Stock Award, to vote Common Stock subject thereto, and
to enjoy all other stockholder rights, except that (i) the Participant shall not be entitled to delivery of the stock certificate
until the Forfeiture Restrictions have expired, (ii) the Company shall retain custody of the stock until the Forfeiture Restrictions
have expired, (iii) the Participant may not sell, transfer, pledge, exchange, hypothecate, or otherwise dispose of or encumber
the stock until the Forfeiture Restrictions have expired, (iv) a breach of the terms and conditions established by the Committee
pursuant to the Restricted Stock Agreement shall result in a forfeiture of the Restricted Stock Award, and (v) with respect to
the payment of any dividend with respect to shares of Common Stock subject to a Restricted Stock Award directly to the Participant,
each such dividend shall be paid no later than the end of the calendar year in which the dividends are paid to stockholders of
such class of shares or, if later, the fifteenth day of the third month following the date the dividends are paid to stockholders
of such class of shares. At the time a Restricted Stock Award is granted, the Committee may, in its sole discretion, prescribe
additional terms, conditions, or restrictions relating to Restricted Stock Awards, including, but not limited to, rules pertaining
to the termination of employment or service as a Consultant or Director (by retirement, disability, death, or otherwise) of a
Participant prior to expiration of the Forfeitures Restrictions. Such additional terms, conditions, or restrictions shall be set
forth in a Restricted Stock Agreement made in conjunction with the Award.


 


(c)Payment
for Restricted Stock. The Committee shall determine the amount and form of any payment for Common Stock received pursuant
to a Restricted Stock Award, provided that in the absence of such a determination, a Participant shall not be required to make
any payment for Common Stock received pursuant to a Restricted Stock Award, except to the extent otherwise required by law.


 


(d)Committee’s
Discretion to Accelerate Vesting of Restricted Stock Awards. Subject to any limitations imposed under section 162(m) of
the Code, the Committee may, in its discretion and as of a date determined by the Committee, fully vest any or all Common Stock
awarded to a Participant pursuant to a Restricted Stock Award and, upon such vesting, all Forfeiture Restrictions applicable to
such Restricted Stock Award shall terminate as of such date. Any action by the Committee pursuant to this Subparagraph may vary
among individual Participants and may vary among the Restricted Stock Awards held by any individual Participant.


 


(e)Restricted
Stock Agreements. At the time any Award is made under this Paragraph VIII, the Company and the Participant shall enter
into a Restricted Stock Agreement setting forth each of the matters contemplated hereby and such other matters as the Committee
may determine to be appropriate. The terms and provisions of the respective Restricted Stock Agreements need not be identical.
Subject to the restriction set forth in the first sentence of Subparagraph (d) above, the Committee may, in its sole discretion,
amend an outstanding Restricted Stock Agreement from time to time in any manner that is not inconsistent with the provisions of
the Plan, provided that, except as otherwise provided in the Plan or the applicable Restricted Stock Agreement, any such amendment
shall not materially reduce the rights of a Participant without the consent of such Participant.

IX.PERFORMANCE
AWARDS


 


(a)Performance
Period. If the Committee grants one or more Performance Awards to a Participant, the Committee shall establish, with respect
to and at the time each such Performance Award is granted, the number of shares of Common Stock subject to, or the maximum value
of, such Performance Award and the performance period over which the performance applicable to such Performance Award shall be
measured.


 


(b)Performance
Measures. A Performance Award shall be awarded to a Participant contingent upon future performance of the Company or any
Affiliate, division, or department thereof under a Performance Measure during the performance period. With respect to Performance
Awards that are intended to constitute “performance-based” compensation under section 162(m) of the Code, the Committee
shall establish the initial Performance Measures applicable to such performance within any time period required under section
162(m) of the Code and applicable authority thereunder. The Committee, in its sole discretion, may provide for an adjustable Performance
Award value based upon the level of achievement of Performance Measures.


 


(c)Awards
Criteria. In determining the value of Performance Awards, the Committee shall take into account a Participant’s
responsibility level, performance, potential, other Awards, and such other considerations as it deems appropriate. The Committee,
in its sole discretion, may provide for a reduction in the value of a Participant’s Performance Award during the performance
period.


 


(d)Payment.
Following the end of the performance period, the holder of a Performance Award shall be entitled to receive payment of an amount
not exceeding the number of shares of Common Stock subject to, or the maximum value of, the Performance Award, based on the achievement
of the Performance Measures for such performance period, as determined and certified in writing by the Committee. Payment of a
Performance Award may be made in cash, Common Stock, or a combination thereof, as determined by the Committee. Payment shall be
made in a lump sum or in installments as prescribed by the Committee. If a Performance Award covering shares of Common Stock is
to be paid in cash, such payment shall be based on the Fair Market Value of the Common Stock on the payment date or such other
date as may be specified by the Committee in the Performance Award Agreement. A Participant shall not be entitled to the privileges
and rights of a stockholder with respect to a Performance Award covering shares of Common Stock until payment has been determined
by the Committee and such shares have been delivered to the Participant.


 


(e)Termination
of Award. A Performance Award shall terminate if the Participant does not remain continuously in the employ of the Company
and its Affiliates or does not continue to perform services as a Consultant or a Director for the Company and its Affiliates at
all times during the applicable performance period through the payment date, except as may be determined by the Committee.

(f)Performance
Award Agreements. At the time any Award is made under this Paragraph IX, the Company and the Participant shall enter into
a Performance Award Agreement setting forth each of the matters contemplated hereby and such additional matters as the Committee
may determine to be appropriate, including, in the discretion of the Committee, the payment of dividend equivalents on any shares
of Common Stock at the time of payment of the Performance Award (or at such other time designated by the Committee) for the period
beginning on the date of grant and ending on the date of payment of the Performance Award (or for such other period designated
by the Committee). The terms and provisions of the respective Performance Award Agreements need not be identical.


 


X.PHANTOM
STOCK AWARDS


 


(a)Phantom
Stock Awards. Phantom Stock Awards are rights to receive shares of Common Stock (or the Fair Market Value thereof), or
rights to receive an amount equal to any appreciation or increase in the Fair Market Value of Common Stock over a specified period
of time, which vest over a period of time as established by the Committee, without satisfaction of any performance criteria or
objectives that are based on one or more Performance Measures. The Committee may, in its discretion, require payment or other
conditions of the Participant respecting any Phantom Stock Award. A Phantom Stock Award may include, without limitation, a Stock
Appreciation Right that is granted independently of an Option; provided, however, that the exercise price per share of Common
Stock subject to the Stock Appreciation Right shall be (i) determined by the Committee but, subject to adjustment as provided
in Paragraph XII, such exercise price shall not be less than the Fair Market Value of a share of Common Stock on the date such
Stock Appreciation Right is granted, and (ii) subject to the restrictions on repricings described in Paragraph VII(f) in the same
manner as applies to Options.


 


(b)Award
Period. The Committee shall establish, with respect to and at the time of each Phantom Stock Award, a period over which
the Award shall vest with respect to the Participant.


 


(c)Awards
Criteria. In determining the value of Phantom Stock Awards, the Committee shall take into account a Participant’s
responsibility level, performance, potential, other Awards, and such other considerations as it deems appropriate.


 


(d)Payment.
Following the end of the vesting period for a Phantom Stock Award (or at such other time as the applicable Phantom Stock Award
Agreement may provide), the holder of a Phantom Stock Award shall be entitled to receive payment of an amount, not exceeding the
maximum value of the Phantom Stock Award, based on the then vested value of the Award. Payment of a Phantom Stock Award may be
made in cash, Common Stock, or a combination thereof as determined by the Committee. Payment shall be made in a lump sum or in
installments as prescribed by the Committee. Any payment to be made in cash shall be based on the Fair Market Value of the Common
Stock on the payment date or such other date as may be specified by the Committee in the Phantom Stock Award Agreement. Cash dividend
equivalents may be paid during or after the vesting period with respect to a Phantom Stock Award, as determined by the Committee.
A Participant shall not be entitled to the privileges and rights of a stockholder with respect to a Phantom Stock Award until
the shares of Common Stock, if any, have been delivered to the Participant.


 




    	 	12	 



     

    

  


(e)Termination
of Award. A Phantom Stock Award shall terminate if the Participant does not remain continuously in the employ of the Company
and its Affiliates or does not continue to perform services as a Consultant or a Director for the Company and its Affiliates at
all times during the applicable vesting period, except as may be otherwise determined by the Committee.


 


(f)Phantom
Stock Award Agreements. At the time any Award is made under this Paragraph X, the Company and the Participant shall enter
into a Phantom Stock Award Agreement setting forth each of the matters contemplated hereby and such additional matters as the
Committee may determine to be appropriate. The terms and provisions of the respective Phantom Stock Award Agreements need not
be identical.


 


XI.BONUS
STOCK AWARDS


 


Each
Bonus Stock Award granted to a Participant shall constitute a transfer of unrestricted shares of Common Stock on such terms and
conditions as the Committee shall determine. Bonus Stock Awards shall be made in shares of Common Stock and need not be subject
to performance criteria or objectives or to forfeiture. The purchase price, if any, for shares of Common Stock issued in connection
with a Bonus Stock Award shall be determined by the Committee in its sole discretion.


 


XII.RECAPITALIZATION
OR REORGANIZATION


 


(a)No
Effect on Right or Power. The existence of the Plan and the Awards granted hereunder shall not affect in any way the right
or power of the Board or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization,
or other change in the Company’s or any Affiliate’s capital structure or its business, any merger, consolidation or
other business combination of the Company or any Affiliate, any issue of debt or equity securities ahead of or affecting Common
Stock or the rights thereof, the dissolution or liquidation of the Company or any Affiliate, any sale, lease, exchange, or other
disposition of all or any part of its assets or business, or any other corporate act or proceeding.


 


(b)Subdivision
or Consolidation of Shares; Stock Dividends. The shares with respect to which Awards may be granted are shares of Common
Stock as presently constituted, but if, and whenever, prior to the expiration of an Award theretofore granted, the Company shall
effect a subdivision or consolidation of shares of Common Stock or the payment of a stock dividend on Common Stock without receipt
of consideration by the Company, the number of shares of Common Stock with respect to which such Award may thereafter be exercised
or satisfied, as applicable, (i) in the event of an increase in the number of outstanding shares, shall be proportionately increased,
and the purchase price per share, if any, shall be proportionately reduced, and (ii) in the event of a reduction in the number
of outstanding shares, shall be proportionately reduced, and the purchase price per share, if any, shall be proportionately increased.
Any fractional share resulting from such adjustment shall be rounded up to the next whole share.


 




    	 	13	 



     

    

  


(c)Recapitalizations
and Corporate Changes. If the Company recapitalizes, reclassifies its capital stock, or otherwise changes its capital
structure or another change or event occurs that constitutes an Equity Restructuring Event (a “recapitalization”),
(A) the Committee shall equitably adjust the number and class of shares of Common Stock (or other securities or property) covered
by each outstanding Award and the terms and conditions, including the exercise price and performance criteria (if any), of such
Award to equitably reflect such recapitalization and shall adjust the number and class of shares of Common Stock (or other securities
or property) with respect to which Awards may be granted after such recapitalization and (B) the Committee shall make a corresponding
and proportionate adjustment with respect to the maximum number of shares of Common Stock (or other securities) that may be delivered
with respect to Awards under the Plan as provided in Paragraph V(a), the individual Award limitations set forth in Paragraph V(a)
and the class of shares of Common Stock (or other securities) available for grant under the Plan. If (i) the Company shall not
be the surviving entity in any merger, consolidation or other business combination or reorganization (or survives only as a subsidiary
of an entity), (ii) the Company sells, leases, or exchanges all or substantially all of its assets to any other person or entity,
(iii) the Company is dissolved and liquidated, (iv) any person or entity, including a “group” as contemplated by section
13(d)(3) of the Exchange Act, acquires or gains ownership or control (including, without limitation, the power to vote) of more
than 50% of the outstanding shares of the Company’s voting stock (based upon voting power), or (v) as a result of or in
connection with a contested election of directors of the Company, the persons who were directors of the Company before such election
shall cease to constitute a majority of the Board (each such event is referred to herein as a “Corporate Change”),
then (x) within 10 days after the consummation by the Company of such merger, consolidation, combination, reorganization, sale,
lease, or exchange of assets or dissolution and liquidation or such change in the Board or (y) no later than 30 days after a Corporate
Change of the type described in clause (iv), the Committee, acting in its sole discretion without the consent or approval of any
Participant, shall effect one or more of the following alternatives in an equitable and appropriate manner to prevent dilution
or enlargement of the benefits or potential benefits intended to be made available under the Plan, which alternatives may vary
among individual Participants and which may vary among Options or Stock Appreciation Rights held by any individual Participant:
(1) accelerate the time at which Options or Stock Appreciation Rights then outstanding may be exercised so that such Awards may
be exercised in full for a limited period of time on or before a specified date fixed by the Committee, after which specified
date all such unexercised Options and Stock Appreciation Rights and all rights of Participants thereunder shall terminate, (2)
require the mandatory surrender to the Company by all or selected Participants of some or all of the outstanding Options or Stock
Appreciation Rights held by such Participants (irrespective of whether such Awards are then exercisable under the provisions of
the Plan) as of a date, before or after such Corporate Change, specified by the Committee, in which event the Committee shall
thereupon cancel such Awards and the Company shall pay (or cause to be paid) to each Participant an amount of cash per share equal
to the excess, if any, of the amount calculated in Subparagraph (d) below (the “Change of Control Value”)
of the shares subject to such Awards over the exercise price(s) under such Awards for such shares, or (3) make such adjustments
to Options or Stock Appreciation Rights then outstanding as the Committee deems appropriate to reflect such Corporate Change and
to prevent the dilution or enlargement of rights (provided, however, that the Committee may determine in its sole discretion that
no adjustment is necessary to such Awards then outstanding), including, without limitation, adjusting such an Award to provide
that the number and class of shares of Common Stock covered by such Award shall be adjusted so that such Award shall thereafter
cover securities of the surviving or acquiring corporation or other property (including, without limitation, cash) as determined
by the Committee in its sole discretion.


 




    	 	14	 



     

    

  


(d)Change
of Control Value. For the purposes of clause (2) in Subparagraph (c) above, the Change of Control Value shall equal the
amount determined in the following clause (i), (ii) or (iii), whichever is applicable: (i) the per share price offered to stockholders
of the Company in any such merger, consolidation, or other business combination, reorganization, sale of assets or dissolution
and liquidation transaction, (ii) the per share price offered to stockholders of the Company in any tender offer or exchange offer
whereby a Corporate Change takes place, or (iii) if such Corporate Change occurs other than pursuant to a tender or exchange offer,
the fair market value per share of the shares into which such Options or Stock Appreciation Rights being surrendered are exercisable,
as determined by the Committee as of the date determined by the Committee to be the date of cancellation and surrender of such
Awards. In the event that the consideration offered to stockholders of the Company in any transaction described in this Subparagraph
(d) or Subparagraph (c) above consists of anything other than cash, the Committee shall determine the fair cash equivalent of
the portion of the consideration offered which is other than cash.


 


(e)Other
Changes in the Common Stock. In the event of changes in the outstanding Common Stock by reason of recapitalizations, reorganizations,
mergers, consolidations, combinations, split-ups, split-offs, spin-offs, exchanges, or other relevant changes in capitalization
or distributions (other than ordinary dividends) to the holders of Common Stock occurring after the date of the grant of any Award
and not otherwise provided for by this Paragraph XII, such Award and any agreement evidencing such Award shall be subject to adjustment
by the Committee at its sole discretion as to the number and price of shares of Common Stock or other consideration subject to
such Award in an equitable and appropriate manner so as to prevent the dilution or enlargement of the benefits or potential benefits
intended to be made available under such Award. In the event of any such change in the outstanding Common Stock or distribution
to the holders of Common Stock, or upon the occurrence of any other event described in this Paragraph XII, the aggregate maximum
number of shares available under the Plan, the aggregate maximum number of shares that may be issued under the Plan through Incentive
Stock Options, and the maximum number of shares that may be subject to Awards granted to any one individual shall be appropriately
adjusted to the extent, if any, determined by the Committee, whose determination shall be conclusive.


 


(f)Stockholder
Action. Any adjustment provided for in the above Subparagraphs shall be subject to any stockholder
action required by applicable law or regulation or the Company’s Articles of Incorporation or bylaws.


 


(g)No
Adjustments Unless Otherwise Provided. Except as hereinbefore expressly provided, the issuance by the Company of shares
of stock of any class or securities convertible into shares of stock of any class, for cash, property, labor or services, upon
direct sale, upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the
Company convertible into such shares or other securities, and in any case whether or not for fair value, shall not affect, and
no adjustment by reason thereof shall be made with respect to, the number of shares of Common Stock subject to Awards theretofore
granted or the purchase price per share, if applicable.

Board in its discretion may terminate the Plan at any time with respect to any shares of Common Stock for which Awards have not
theretofore been granted. The Board shall have the right to alter or amend the Plan or any part thereof from time to time; provided

granted without the consent of the Participant, and provided, further, that the Board may not, without approval of the stockholders
of the Company, (a) amend the Plan to increase the aggregate maximum number of shares that may be issued under the Plan, increase

without the consent of any Participant or beneficiary of any Award, to adopt any such clawback policies and procedures, including
such policies and procedures applicable to the Plan or any Award agreement with retroactive effect.


 


(g)Delayed
Payment Restriction. Notwithstanding any provision in the Plan or an Award agreement to the contrary, if any payment or
