ARTICLE I
  
    Plan    
    

        1.1    Purpose.    This Plan is intended to advance the best interests of the Company, its Affiliates, and its
shareholders by providing those persons who have substantial responsibility for the management and growth of the Company and its Affiliates with additional incentives and an opportunity to obtain or
increase their proprietary interest in the Company, thereby encouraging them to continue to provide services to the Company or any of its Affiliates. 

        1.2    Effective Date of Plan.    This Plan is effective May 1, 1997, if within one year of that date it shall
have been approved by at least a majority vote of shareholders voting in person or by proxy at a duly held shareholders' meeting, or if the provisions of the Company's Articles of Incorporation or
By-laws or applicable state law prescribes a greater degree of shareholder approval for this action, the approval by the holders of that percentage, at a duly held meeting of shareholders.
No Incentive Option or Nonqualified Option shall be granted pursuant to this Plan after April 30, 2007.

corporation (other than the Company) in an unbroken chain of corporations ending with the Company if, at the time of the action or transaction, each of the corporations other than the Company owns
stock possessing more than 50% of the total combined voting power of all classes of stock in one of the other corporations in the chain. The term "subsidiary corporation" means any corporation (other
than the Company) in an unbroken chain of corporations beginning with the Company if, at the time of the action or transaction, each of the corporations other than the last corporation in the unbroken

whether such employee is disabled, then the Company and such employee shall obtain a determination from an impartial reputable physician selected for the purpose of making such determination, whose
decision shall be binding upon all parties. If the Company and such employee cannot agree upon the selection of such physician, the then current president of the Harris County, Texas, Medical Society

changed into or exchanged for a different class of stock or securities of the Company or another corporation, that other stock or security.

total combined voting power of all classes of stock of the Company or of any Affiliate. An individual shall be considered as owning the stock owned, directly or indirectly, by or for his brothers and

ARTICLE IV
  
    General Provisions Relating to Options    
    

        4.1    Authority to Grant Options.    The Committee may grant Options to persons selected by it in accordance with the
terms and conditions of this Plan. Subject only to any applicable limitations set out in this Plan, the number of shares of Stock to be covered by any Option to be granted to an Optionee shall be as
determined by the Committee. 

        4.2    Dedicated Shares.    The total number of shares of Stock with respect to which Options may be granted under the
Plan shall be 58,665 shares. The shares may be treasury shares or authorized but unissued shares. The number of shares stated in this Section 4.2 shall be subject to adjustment in accordance
with the provisions of Section 4.5. 

2

 

        In
the event that any outstanding Option shall expire or terminate for any reason or any Option is surrendered, the shares of Stock allocable to the unexercised portion of that Option
may again be subject to an Option under the Plan. 

        4.3    Non-Transferability.    Options shall not be transferable by the Optionee otherwise than by will or
under the laws of descent and distribution, and shall be exercisable, during the Optionee's lifetime, only by him. 

        4.4    Requirements of Law.    The Company shall not be required to sell or issue any Stock under any Option if
issuing that Stock would constitute or result in a violation by the Optionee or the Company of any provision of any law, statute, or regulation of any governmental authority. Specifically, in
connection with any applicable statute or regulation relating to the registration of securities, upon exercise of any Option, the Company shall not be required to issue any Stock unless the Committee
has received evidence satisfactory to it to the effect that the holder of that Option will not transfer the Stock except in accordance with applicable law, including receipt of an opinion of counsel
satisfactory to the Company to the effect that any proposed transfer complies with applicable law. The determination by the Committee on this matter shall be final, binding and conclusive. The Company
may, but shall in no event be obligated to, register any Stock covered by this Plan pursuant to applicable securities laws of any country or any political subdivision. In the event the Stock issuable
on exercise of an Option is not registered, the Company may imprint on the certificate evidencing the Stock any legend that counsel for the Company considers necessary or advisable to comply with
applicable law. The Company shall not be obligated to take any other affirmative action in order to cause the exercise of an Option and the issuance of shares thereunder, to comply with any law or
regulation of any governmental authority. 

        4.5    Changes in the Company's Capital Structure.    (a) The existence of outstanding Options shall not affect
in any way the right or power of the Company or its shareholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company's capital structure or
its business, or any merger or consolidation of the Company, or any issue of bonds, debentures, preferred or prior preference stock ahead of or affecting the Stock or its rights, or the dissolution or
liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise. 

        (b)   If
the Company shall effect a subdivision or consolidation of shares or other capital adjustment of, or the payment of a dividend in capital stock or other equity
securities of the Company on, Stock, or other increase or reduction of the number of shares of Stock without receiving consideration therefor in money, services, or property, or the reclassification
of Stock, in whole or in part, into other equity securities of the Company, then (i) the number, class and per share price of shares of Stock subject to outstanding Options hereunder shall be
appropriately adjusted (or in the case of the issuance of other equity securities as a dividend on, or in a reclassification of, Stock, the Options shall extend to such other securities) in such a
manner as to entitle an Optionee to receive, upon exercise of an Option, for the same aggregate cash consideration, the same total number and class or classes of shares (or in the case of a dividend
of, or reclassification into, other equity securities, such other securities) he would have held after such adjustment if he had exercised his Option in full 

3

 

immediately
prior to the event requiring the adjustment, or, if applicable, the record date for determining shareholders to be affected by such adjustment; and (ii) the number and class of
shares then reserved for issuance under this Plan (or in the case of a dividend of, or reclassification into, other equity securities, such other securities) shall be adjusted by substituting for the
total number and class of shares of Stock then received, the number and class or classes of shares of Stock (or in the case of a dividend of, or reclassification into, other equity securities, such
other securities) that would have been received by the owner of an equal number of outstanding shares of Stock as a result of the event requiring the adjustment. Comparable rights shall accrue to each
Optionee in the event of successive subdivisions, consolidations, capital adjustments, dividends or reclassifications of the character described above. 

        (c)   If
(i) the Company shall not be the surviving entity in any merger, consolidation or other reorganization (or survives only as a subsidiary of an entity other
than a previously wholly-owned subsidiary of the Company), (ii) the Company sells, leases or exchanges or agrees to sell, lease or exchange all or substantially all of its assets to any other
person or entity (other than a wholly-owned subsidiary of the Company), or (iii) the Company is to be dissolved and liquidated (each such event is referred to herein as a "Corporate Change"),
no later than ten (10) days after the approval by the shareholders of the Company of such merger, consolidation, reorganization, sale, lease or exchange of assets or dissolution, the Committee,
acting in its sole discretion without the consent or approval of any Optionee, shall act to effect one or more of the following alternatives, which may vary among individual Optionees and which may
vary among Options held by any individual Optionee: (1) accelerate the time at which Options then outstanding may be exercised so that such Options may be exercised in full for a limited period
of time on or before a specified date (before or after such Corporate Change) fixed by the Committee, after which specified date all unexercised Options and all rights of Optionees thereunder shall
terminate, (2) require the mandatory surrender to the Company by selected Optionees of some or all of the outstanding Options held by such Optionees (irrespective of whether such Options are
then exercisable under the provisions of this Plan or the Option Agreements evidencing such Options) as of a date, before or after such Corporate Change, specified by the Committee, in which event the
Committee shall thereupon cancel such Options and the Company shall pay to each Optionee an amount of cash per share equal to the excess, if any, of the per share price offered to shareholders of the
Company in any such merger, consolidation, reorganization, sale of assets or dissolution transaction over the exercise price(s) under such Options for such shares, (3) make such adjustments to
the number and class of shares then reserved for issuance under this Plan and/or to Options then outstanding as the Committee deems appropriate to reflect such Corporate Change, including, but not
limited to, having Options then outstanding assumed by the corporation surviving as a result of such Corporate Change and/or having a new option substituted by such surviving corporation for Options
then outstanding (provided, however, that the Committee may determine in its sole discretion that no such adjustment is necessary), or (4) provide that the number and class of shares of Stock
covered by an Option theretofore granted shall be adjusted so that such Option shall thereafter cover the number and class of shares of stock or other securities or property (including, without
limitation, cash) to which the Optionee would have been entitled pursuant to the terms of the agreement of merger, consolidation or sale of assets and dissolution if, immediately prior to such merger,
consolidation or sale of assets and dissolution, the Optionee had been the holder of record of the number of shares of Stock then covered by such Option. 

4

 

        (d)   In
the event of changes in the outstanding Stock by reason of recapitalizations, reorganizations, mergers, consolidations, combinations, exchanges or other relevant
changes in capitalization occurring after the date of the grant of any Option and not otherwise provided for by this Section 4.5, any outstanding Options and any agreements evidencing such
Options shall be subject to adjustment by the Committee at its discretion as to the number and price of shares of stock or other consideration subject to such Options. In the event of any such change
in the outstanding Stock, the aggregate number of shares available under this Plan may be appropriately adjusted by the Committee, whose determination shall be conclusive. 

        (e)   The
issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or property, or for labor or services
either upon direct sale or upon the exercise of rights or warrants to subscribe for them, or upon conversion of shares or obligations of the Company convertible into shares or other securities, shall
not affect, and no adjustment by reason of such issuance shall be made with respect to, the number, class, or price of shares of Stock then subject to outstanding Options. 

        4.6    Market Stand-Off Agreement.    In connection with any underwritten public offering after the
effective date of this Plan pursuant to an effective registration statement under the Securities Act of 1933, as amended, or any successor Federal statute, and the rules and regulations of the
Securities and Exchange Commission promulgated thereunder, as in effect from time to time (the "Securities Act"), covering the offering and sale of shares of Stock, or of any equity security that as a
part of a unit includes Stock, for the account of the Company, an Optionee, if and to the extent requested in good faith by the Company and the managing underwriter of securities of the Company, shall
agree not to sell or otherwise transfer or dispose of any shares of Stock held by him or her or acquired by him or her pursuant to the exercise of an Option (except shares of Stock included in the
registration statement relating to such underwritten public offering) at any time during a period following the effective date of the registration statement relating to such underwritten public
offering; provided, however, that in no event shall such period exceed 180 days. In order to
enforce the foregoing covenant, subject to the foregoing exceptions, the Company may impose stop-transfer instructions with respect to such shares of Stock of an Optionee (and the
securities of every other person subject to such restriction) until the end of such period. The provisions of this Section 4.6 shall apply until the earlier to occur of (i) five
(5) years following the effective date of the "First Qualified Public Offering" (as hereinafter defined), or (ii) such time as an Optionee can sell all remaining shares of Stock held by
him or her within a ninety (90) day period pursuant to Rule 144 or 145 under the Securities Act. For purposes of this Section 4.6, the term "First Qualified Public Offering" means
a firm commitment underwriting that satisfies any requirement contained in the Company's charter document relating to the aggregate net proceeds attributable to sales for the account of the Company
with respect to an underwritten public offering or, if the Company's charter document contains no such requirement, the first underwritten public offering of the Company for the sale of Stock of which
the aggregate net proceeds attributable to sales for the account of the Company exceed $20,000,000. 

 
 

ARTICLE V
  
    Options    
    

        5.1    Type of Option.    The Committee shall specify whether a given Option shall constitute an Incentive Option or a
Nonqualified Option. 

5

 

        5.2    Option Price.    The price at which Stock may be purchased under an Incentive Option shall not be less than the
greater of: (a) 100% of the Fair Market Value of the shares of Stock on the date the Option is granted or (b) the aggregate par value of the shares of Stock on the date the Option is
granted or, if the Shares are without par value on the date the Option is granted, such consideration, expressed in dollars, as may be fixed from time to time by the Board of Directors. The Committee
in its discretion may provide that the price at which shares of Stock may be purchased under an Incentive Option shall be more than 100% of Fair Market Value. In the case of any 10% Shareholder, the
price at which shares of Stock may be purchased under an Incentive Option shall not be less than 110% of the Fair Market Value of the Stock on the date the Incentive Option is granted. 

        The
price at which shares of Stock may be purchased under a Nonqualified Option shall not be less than the greater of: (a) 80% of the Fair Market Value of the shares of Stock on
the date the Option is granted or (b) the aggregate par value of the shares of Stock on the date the Option is granted or, if the Shares are without par value on the date the Option is granted,
such consideration, expressed in dollars, as may be fixed from time to time by the Board of Directors. The Committee in its discretion may provide that the price at which shares of Stock may be
purchased under a Nonqualified Option shall be more than 100% of Fair Market Value. 

        5.3    Duration of Options.    No Option shall be exercisable after the expiration of ten (10) years from the
date the Option is granted. In the case of a 10% Shareholder, no Incentive Option shall be exercisable after the expiration of five years from the date the Incentive Option is granted. 

        5.4    Amount Exercisable—Incentive Options.    Each Option may be exercised from time to time, in whole
or in part, in the manner and subject to the conditions the Committee, in its sole discretion, may provide in the Option Agreement, as long as the Option is valid and outstanding. To the extent that
the aggregate Fair Market Value (determined as of the time an Incentive Option is granted) of the Stock with respect to which Incentive Options first become exercisable by the Optionee during any
calendar year (under this Plan and any other incentive stock option plan(s) of the Company or any Affiliate) exceeds $100,000, the Incentive Options shall be treated as Nonqualified Options. In making
this determination, Incentive Options shall be taken into account in the order in which they were granted. 

        5.5    Exercise of Options.    Each Option shall be exercised by the delivery of written notice to the Committee
setting forth the number of shares of Stock with respect to which the Option is to be exercised, together with: (a) cash, certified check, bank draft, or postal or express money order payable
to the order of the Company, (b) Stock at its Fair Market Value on the date of exercise, and/or (c) any other form of payment which is acceptable to the Committee, in each case for an
amount equal to the exercise price of such shares, and specifying the address to which the certificates for such shares are to be mailed; provided,  however,
 that any share of Stock delivered as payment, in whole or in part, of such exercise price must either (i) not have been acquired by the
Optionee from the Company, or (ii) have been held by the Optionee for at least six (6) months prior to such exercise. As promptly as practicable after receipt of written notification and
payment, the Company shall deliver to the Optionee certificates for such shares, issued in the Optionee's name. If shares of Stock are used in payment of the exercise price, the aggregate Fair Market
Value of the shares of Stock tendered must be equal to or less than the aggregate exercise price of the shares being purchased upon exercise of the Option, and any difference must be paid by cash,
certified check, bank draft or postal or express money order payable to the Company. Delivery of the shares shall be deemed effected for all purposes when a stock transfer agent of the Company shall
have deposited the certificates in the United States mail, addressed to the Optionee, at the address specified by the Optionee in his notice of exercise. 

6

 

        Whenever
an Option is exercised by exchanging shares of Stock owned by the Optionee, the Optionee shall deliver to the Company certificates registered in the name of the Employee
representing a number of shares of Stock legally and beneficially owned by the Optionee, free of all liens, claims, and encumbrances of every kind, accompanied by stock powers duly endorsed in blank
by the record holder of the shares represented by the certificates, (with signature guaranteed by a commercial bank or trust company or by a brokerage firm having a membership on a registered national
stock exchange). The delivery of certificates upon the exercise of Options is subject to the condition that the person exercising the Option provide the Company with the information the Company might
reasonably request pertaining to exercise, sale or other disposition of an Option. 

        5.6    Exercise on Termination of Employment.    

        (a)    Termination Other Than By Death or Disability.    Unless it is expressly provided
otherwise in the Option Agreement, each Option shall terminate on the earlier of the date of expiration of the Option or the date that is one day less than three months after the severance of the
employment relationship between the Optionee and the Company and all Affiliates for any reason (including, but not limited to, Retirement), whether with or without cause, other than death or
Disability (the earlier of such dates being referred to herein as the "Option Termination (Severance) Date"), and during such period the Optionee shall be entitled, at any time prior to the Option
Termination (Severance) Date, to exercise the Option in respect of the number of shares that the Optionee would have been entitled to purchase had the Optionee exercised the Option immediately prior
to such severance of employment. If such Optionee should die after such severance of employment and prior to the Option Termination (Severance) Date, any rights such Optionee may have to exercise the
Option shall be exercisable by the Optionee's executors or administrators or the person or persons to whom the Option shall have been transferred by his will or by the laws of descent or distribution,
as applicable, for the remainder of the period prior to the Option Termination (Severance) Date, unless it is expressly provided otherwise in the Option Agreement. Whether authorized leave of absence
or absence on military or government service shall constitute severance of the employment of the Employee shall be determined by the Committee at that time. 

        In
determining the employment relationship between the Company and the Employee, employment by any Affiliate shall be considered employment by the Company, as shall employment by a
corporation issuing or assuming a stock option in a transaction to which Section 424(a) of the Code applies, or by a parent corporation or subsidiary corporation of the corporation issuing or
assuming a stock option (and for this purpose, the phrase "corporation issuing or assuming a stock option" shall be substituted for the word "Company" in the definitions of parent corporation and
subsidiary corporation in Section 2.1, and the parent-subsidiary relationship shall be determined at the time of the corporate action described in Section 424(a) of the Code). 

        (b)    Death.    If the Optionee, while in the employ of the Company and before the date of
expiration of the Option, dies, the Option shall terminate on the earlier of the date of expiration of the Option or the date that is one day less than one year following the date of the Optionee's
death (the earlier of such dates being referred to herein as the "Option Termination (Death) Date"), unless it is expressly provided otherwise in the Option Agreement. After the death of the Optionee
while in the employ of the Company and before the Option Termination (Death) Date, the Optionee's executors or administrators or any person or persons to whom his Option shall have been transferred by
his will or by the laws of descent and distribution, as applicable, shall have the right, at any time prior to the Option Termination (Death) Date, to exercise the Option in respect of the number of
shares that the Optionee would have been entitled to purchase had he exercised the Option immediately prior to his death, unless it is expressly provided otherwise in the Option Agreement. 

7

 

        (c)    Disability.    If, before the expiration of an Option, the Optionee shall be severed
from the employ of the Company and all Affiliates for Disability, the Option shall terminate on the earlier of the date of expiration of the Option or the date that is one day less than one year after
the date the Optionee was severed because of Disability (the earlier of such dates being referred to herein as the "Option Termination (Disability) Date"), unless it is expressly provided otherwise in
the Option Agreement. Unless it is expressly provided otherwise in the Option Agreement, in the event that the Optionee shall be severed from the employ of the Company and all Affiliates for
Disability, the Optionee shall have the right prior to the Option Termination (Disability) Date to exercise the Option in respect of the number of shares that the Optionee would have been entitled to
purchase had the Optionee exercised the Option immediately prior to his severance of employment for Disability. If such Optionee should die after such severance of employment for Disability and prior
to the Option Termination (Disability) Date, any rights such Optionee may have to exercise the Option shall be exercisable by his executors or administrators or the person or persons to whom the
Option shall have been transferred by his will or by the laws of descent or distribution, as applicable, for the remainder of the period prior to the Option Termination (Disability) Date, unless it is
expressly provided otherwise in the Option Agreement. 

        5.7    Substitution Options.    Options may be granted under this Plan from time to time in substitution for stock
options held by employees of other corporations who are about to become employees of or affiliated with the Company or any Affiliate as the result of a merger or consolidation of the employing
corporation with the Company or any Affiliate, or the acquisition by the Company or any Affiliate of the assets of the employing corporation, or the acquisition by the Company or any Affiliate of
stock of the employing corporation as the result of which it becomes an Affiliate of the Company. The terms and conditions of the substitute Options granted may vary from the terms and conditions set
out in this Plan to the extent the Committee, at the time of grant, may deem appropriate to conform, in whole or in part, to the provisions of the stock options in substitution for which they are
granted. 

        5.8    No Rights as Shareholder.    No Optionee shall have any rights as a shareholder with respect to Stock covered
by his Option until the date a stock certificate is issued for the Stock. 

 
 

ARTICLE VI
  
    Administration    
    

        This Plan shall be administered by the Committee. All questions of interpretation and application of this Plan and Options shall be subject to the determination
of the Committee. A majority of the members of the Committee shall constitute a quorum. All determinations of the Committee shall be made by a majority of its members. Any decision or determination
reduced to writing and signed by a majority of the members shall be as effective as if it had been made by a majority vote at a meeting properly called and held. This Plan shall be administered in
such a manner as to permit the Options granted under it that are designated to be Incentive Options to qualify as Incentive Options. In carrying out its authority under this Plan, the Committee shall
have full and final authority and discretion, including but not limited to the following rights, powers and authorities, to: 

        (a)   determine

ARTICLE VII
  
    Amendment or Termination of Plan    
    

        The Board of Directors of the Company may amend, terminate or suspend this Plan at any time, in its sole and absolute discretion; provided, however, that to the
extent required to maintain the status of any Incentive Option under the Code, no amendment that would (a) change the aggregate number of shares of Stock that may be issued under Incentive
Options, (b) change the class of employees eligible to receive Incentive Options, or (c) decrease the exercise price for Incentive Options below the Fair Market Value of the Stock at the
time it is granted, shall be made without the approval of the holders of a majority of the outstanding shares of the Company's voting stock present in person or by proxy and entitled to vote thereon.
Subject to the preceding sentence, the Board shall have the power to make any changes in this Plan and in the regulations and administrative provisions under it or in any outstanding Incentive Option
as in the opinion of counsel for the Company may be necessary or appropriate from time to time to enable any Incentive Option granted under this Plan to continue to qualify as an incentive stock
option or such other stock option as may be defined under the Code so as to receive preferential federal income tax treatment. 

 
 

ARTICLE VIII
  
    Miscellaneous    
    

        8.1    No Employment or Affiliation Obligation.    The granting of any Option shall not constitute an employment or
consulting contract, express or implied, nor impose upon the Company or any Affiliate any obligation to employ or to retain or to continue to retain the services of any Optionee. The right of the
Company or any Affiliate to terminate the employment or retention of any person shall not be diminished or affected by reason of the fact that an Option has been granted to him. 

        8.2    Forfeiture.    Notwithstanding any other provisions of this Plan, if during the time that an Optionee holds an
Option the Committee finds by a majority vote after full consideration of the facts that the Optionee (a) committed or engaged in fraud, embezzlement, theft, commission of a felony, or proven
dishonesty in the course of his employment by or affiliation with the Company or an Affiliate, which conduct damaged the Company or an Affiliate, or disclosed trade secrets of the Company or an
Affiliate, or (b) participated, engaged in or had a material, financial or other interest, whether as an employee, officer, director, consultant, contractor, shareholder, owner, or otherwise,
in any commercial endeavor anywhere in the world where the Company conducts business that is competitive with the business of the Company or an Affiliate without the written consent of the Company or
such Affiliate, then the Optionee shall forfeit all outstanding Options, including all exercised Options pursuant to which the Company has not yet delivered a stock certificate. Clause (b)
shall not be deemed to have been violated solely by reason of the Optionee's ownership of stock or securities of any publicly owned corporation, if that ownership does not result in effective control
of such corporation. 

        The
decision of the Committee as to the damage done to the Company or an Affiliate, and the extent of the Optionee's competitive activity shall be final. 

9

 

        8.3    Tax Withholding.    The Company or any Affiliate shall be entitled to deduct from other compensation payable to
each Optionee who is an employee of the Company or an Affiliate any sums required by federal, state, or local tax law to be withheld with respect to the grant or exercise of an Option. In the
alternative, the Company may require the Optionee (or other person exercising the Option) to pay the sum directly to the employer corporation. If the Optionee (or other person exercising the Option)
is required to pay the sum directly, payment in cash or by check of such sums for taxes shall be delivered within 10 days after the date of exercise or lapse of restrictions. The Company shall
have no obligation upon exercise of any Option until payment has been received, unless withholding (or offset against a cash payment) as of or prior to the date of exercise is sufficient to cover all
sums due with respect to that exercise. The Company and its Affiliates shall not be obligated to advise an Optionee of the existence of the tax or the amount that the employer corporation will be
required to withhold. 

        8.4    Written Agreement.    Each Option shall be embodied in a written Option Agreement which shall be subject to the
terms and conditions of this Plan and shall be signed by the Optionee and by a member of the Committee on behalf of the Committee and the Company. The Option Agreement may contain any other provisions
that the Committee in its discretion shall deem advisable which are not inconsistent with the terms of this Plan. 

        8.5    Indemnification of the Committee and the Board of Directors.    With respect to administration of this Plan,
the Company shall indemnify each present and future member of the Committee and the Board of Directors against, and each member of the Committee and the Board of Directors shall be entitled without
further act on his part to indemnity from the Company for, all expenses (including attorney's fees, the amount of judgments and the amount of approved settlements made with a view to the curtailment
of costs of litigation, other than amounts paid to the Company itself) reasonably incurred by him in connection with or arising out of any action, suit, or proceeding in which he may be involved by
reason of his being or having been a member of the Committee and/or the Board of Directors, whether or not he continues to be a member of the Committee and/or the Board of Directors at the time of
incurring the expenses—including, without limitation, matters as to which he shall be finally adjudged in any action, suit or proceeding to have been found to have been negligent in the
performance of his duty as a member of the Committee of the Board of Directors. However, this indemnity shall not include any expenses incurred by any member of the Committee and/or the Board of
Directors in respect of matters as to which he shall be finally adjudged in any action, suit or proceeding to have been guilty of gross negligence or willful misconduct in the performance of his duty
as a member of the Committee or the Board of Directors. In addition, no right of indemnification under this Plan shall be available to or enforceable by any member of the Committee and the Board of
Directors unless, within 60 days after institution of any action, suit or proceeding, he shall have offered the Company, in writing, the opportunity to handle and defend same at its own
expense. This right of indemnification shall inure to the benefit of the heirs, executors or administrators of each member of the Committee and the Board of Directors and shall be in addition to all
other rights to which a member of the Committee and the Board of Directors may be entitled as a matter of law, contract, or otherwise. 

        8.6    Gender.    If the context requires, words of one gender when used in this Plan shall include the others and
words used in the singular or plural shall include the other. 

        8.7    Headings.    Headings of Articles and Sections are included for convenience of reference only and do not
constitute part of this Plan and shall not be used in construing the terms of this Plan. 

        8.8    Other Compensation Plans.    The adoption of this Plan shall not affect any other stock option, incentive or
other compensation or benefit plans in effect for the Company or any Affiliate, nor shall this Plan preclude the Company from establishing any other forms of incentive or other compensation for
employees of the Company or any Affiliate. 

10

 

        8.9    Other Options.    The grant of an Option shall not confer upon the Optionee the right to receive any future or
other Options under this Plan, whether or not Options may be granted to similarly situated Optionees, or the right to receive future Options upon the same terms or conditions as previously granted. 

        8.10    Governing Law.    The provisions of this Plan shall be construed, administered, and governed under the laws of
the State of Texas.

Option shall be exercisable in full; and 

        (4)   to
the extent not exercised, installments shall be cumulative and may be exercised in whole or in part until the Option expires on the seventh anniversary of the Date of
Grant. 

               (b)   Notwithstanding
the provisions of Section 1(a) hereof, the Option shall be fully exercisable upon the occurrence of any of the following on or after

the extent that the aggregate fair market value of Stock with respect to which incentive stock options are exercisable for the first time by the Employee during any
calendar year (under the Plan or any other plan of the Company or its Affiliates) exceeds $100,000, the options will be treated as nonqualified stock options. For purposes of this rule, the fair
market value of the Stock is determined at the time the option for the Stock is granted. 

        4.     The
Option granted to the Employee under this Agreement shall not be transferable or assignable by the Employee other than by will or the laws of descent and

Directors of the Company, in its discretion, may require to evidence such persons' agreement to be bound by the terms and provisions of the Shareholders Agreement. 

        6.     THE EMPLOYEE IS HEREBY NOTIFIED THAT IF HE DISPOSES OF STOCK TRANSFERRED TO HIM UPON HIS EXERCISE OF THIS OPTION WITHIN TWO YEARS AFTER THE DATE
OF THE GRANTING OF THE OPTION OR WITHIN ONE YEAR AFTER THE TRANSFER OF THE STOCK TO HIM, ALL OR A PORTION OF HIS OPTION WILL BE TAXED AS IF IT WERE A NONQUALIFIED STOCK OPTION RATHER THAN AN INCENTIVE

right, at any time prior to the Option Termination (Death) Date, to exercise the Option in respect of the number of shares that the Employee would have been entitled to purchase had the Employee
exercised the Option immediately prior to his death. 

        (c)   If,
before the Expiration Date, the Employee shall be severed from the employ of the Company and all Affiliates for Disability, the Option shall terminate on the earlier
of the Expiration Date or the date that is one day less than one year after the date of such severance of employment because of Disability (the earlier of such dates being referred to herein as the
"Option Termination (Disability) Date"), and during such period the Employee shall have the right, at any time prior to the Option Termination (Disability) Date, to exercise the Option in respect of
the number of shares that the Employee would have been entitled to purchase had the Employee exercised the Option immediately prior to such severance of employment for Disability. If the Employee
should die after such severance of employment for Disability and prior to the Option Termination (Disability) Date, any rights the Employee may have to exercise the Option shall be exercisable by his
executors or administrators or the person or persons to whom the Option shall have been transferred by his will or by the laws of descent or distribution, as applicable, for the remainder of the
period prior to the Option Termination (Disability) Date.

Option shall terminate and shall not be exercisable in any event after                        ,

Agreement may not be changed or terminated orally but only by an agreement in writing signed by the party against whom enforcement of any such change or termination
is sought. 

        9.     The
Company shall not be deemed by the grant of the Option (as distinguished from a separate employment agreement, if any) to be required to employ the Employee for any
period. 

        10.   The
Employee shall not have any rights as a shareholder with respect to any shares covered by the Option until the date of the issuance of the stock certificate or
certificates to him for such shares following his exercise of the Option pursuant to its terms and conditions and payment for the shares. No adjustment shall be made for dividends or other rights for
which the record date is prior to the date such certificate or certificates are issued. 

        11.   In
the event of any difference of opinion concerning the meaning or effect of the Plan or this Agreement, such difference shall be resolved by the Committee referred to
in the Plan.

        12.   The
validity, construction and performance of this agreement shall be governed by the laws of the State of Texas. Any invalidity of any provision of this Agreement shall
not affect the validity of any other provision. 

        13.   All

        14.   This
Agreement shall, except as herein stated to the contrary, inure to the benefit of and bind the legal representatives, successors and assigns of the parties hereto.

year following the calendar year in which occurred the first registration of an equity security under section 12 of the Exchange Act; or (ii) such 

other

6. Option Provisions.    
    

        Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The provisions of separate Options need not be
identical, but each Option shall
include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions: 

        (a)   Term. No Option shall be exercisable after the expiration of ten (10) years from the date it was granted. 

        (b)   Price. The exercise price of each Incentive Stock Option shall be not less than one hundred percent (100%) of the Fair
Market Value of the stock subject to the Option on the date the Option is granted; the exercise price of each Nonstatutory Stock Option shall be not less than eighty-five percent (85%) of
the Fair Market Value of the stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Option (whether an Incentive Stock Option or a Nonstatutory Stock Option)
may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying
the provisions of Section 424(a) of the Code. 

        (c)   Consideration. The purchase price of stock acquired pursuant to an Option shall be paid, to the extent permitted by
applicable statutes and regulations, either (i) in cash at the time the Option is exercised, or (ii) at the discretion of the Board or the Committee, at the time of the grant of the
Option, (A) by delivery to the Company of other common stock of the Company, (B) according to a deferred payment or other arrangement (which may include, without limiting the generality
of the foregoing, the use of other common stock of the Company) with the person to whom the Option is granted or to whom the Option is transferred pursuant to subsection 6(d), or (C) in any
other form of legal consideration that may be acceptable to the Board. 

        In
the case of any deferred payment arrangement, interest shall be compounded at least annually and shall be charged at the minimum rate of interest necessary to avoid the treatment as
interest, under any applicable provisions of the Code, of any amounts other than amounts stated to be interest under the deferred payment arrangement. 

        (d)   Transferability. An Option shall not be transferable except by will or by the laws of descent and distribution, and shall
be exercisable during the lifetime of the person to whom the Option is granted only by such person. The person to whom the Option is granted may, by delivering written notice to the Company, in a form
satisfactory to the Company, designate a third party who, in the event of the death of the Optionee, shall thereafter be entitled to exercise the Option. 

        (e)   Vesting. The total number of shares of stock subject to an Option may, but need not, be allotted in periodic installments
(which may, but need not, be equal). The Option Agreement may provide that from time to time during each of such installment periods, the Option may become exercisable ("vest") with respect to some or
all of the shares allotted to that period, and may be exercised with respect to some or all of the shares allotted to such period and/or any prior period as to which the Option became vested but was
not fully exercised. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the Board may
deem appropriate. The vesting provisions of individual Options may vary but in each case will provide for vesting of at least twenty percent (20%) per year of the total number of shares subject to the
Option. The provisions of this subsection 6(e) are subject to any Option provisions governing the minimum number of shares as to which an Option may be exercised. 

        (f)    Termination of Employment or Relationship as a Director or Consultant. In the event an Optionee's Continuous Status as an
Employee, Director or Consultant terminates (other than upon the Optionee's death or disability), the Optionee may exercise his or her Option (to the extent that the 

Optionee
was entitled to exercise it as of the date of termination) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination
of the Optionee's Continuous Status as an Employee, Director or Consultant (or such longer or shorter period, which shall not be less than thirty (30) days, unless such termination is for
cause, specified in the Option Agreement), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionee does not exercise his or
her Option within the time specified in the Option Agreement, the Option shall terminate, and the shares covered by such Option shall revert to and again become available for issuance under the Plan. 

        An
Optionee's Option Agreement may also provide that if the exercise of the Option following the termination of the Optionee's Continuous Status as an Employee, Director, or Consultant
(other than upon the Optionee's death or disability) would result in liability under Section 16(b) of the Exchange Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in the Option Agreement, or (ii) the tenth (10th) day after the last date on which such exercise would result in such liability under
Section 16(b) of the Exchange Act. Finally, an Optionee's Option Agreement may also provide that if the exercise of the Option following the termination of the Optionee's Continuous Status as
an Employee, Director or Consultant (other than upon the Optionee's death or disability) would be prohibited at any time solely because the issuance of shares would violate the registration
requirements under the Securities Act, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option set forth in the first paragraph of this subsection 6(f),
or (ii) the expiration of a period of three (3) months after the termination of the Optionee's Continuous Status as an Employee, Director or Consultant during which the exercise of the
Option would not be in violation of such registration requirements. 

        (g)   Disability of Optionee. In the event an Optionee's Continuous Status as an Employee Director or Consultant terminates as
a result of the Optionee's disability, the Optionee may exercise his or her Option (to the extent that the Optionee was entitled to exercise it as of the date of termination), but only within such
period of time ending on the earlier of (i) the date twelve (12) months following such termination (or such longer or shorter period, which in no event shall be less than six
(6) months, specified in the Option Agreement), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, at the date of termination, the Optionee is not
entitled to exercise his or her entire Option, the shares covered by the unexercisable portion of the Option shall revert to and again become available for issuance under the Plan. If, after
termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall terminate, and the shares covered by such Option shall revert to and again become
available for issuance under the Plan. 

        (h)   Death of Optionee. In the event of the death of an Optionee during, or within a period specified in the Option Agreement
after the termination of, the Optionee's Continuous Status as an Employee, Director or Consultant, the Option may be exercised (to the extent the Optionee was entitled to exercise the Option as of the
date of death) by the Optionee's estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the option upon the Optionee's death
pursuant to subsection 6(d), but only within the period ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer or shorter period, which in
no event shall be less than six (6) months, specified in the Option Agreement), or (ii) the expiration of the term of such Option as set forth in the Option Agreement. If, at the time of
death, the Optionee was not entitled to exercise his or her entire Option, the shares covered by the unexercisable portion of the Option shall revert to and again become available for issuance under
the Plan. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate, and the shares covered by such Option shall revert to and again become available
for issuance under the Plan. 

        (i)    Early Exercise. The Option may, but need not, include a provision whereby the Optionee may elect at any time while an
Employee, Director or Consultant to exercise the Option as to any part or all of the shares subject to the Option prior to the full vesting of the Option. Any unvested shares so purchased shall be
subject to a repurchase right in favor of the Company, with the repurchase price to be equal to the original purchase price of the stock, or to any other restriction the Board determines to 

be
appropriate; provided, however, that (i) the right to repurchase at the original purchase price shall lapse at a minimum rate of twenty
percent (20%) per year over five (5) years from the date the Option was granted, and (ii) such repurchase right shall be exercisable only within (A) the one hundred and twenty
(120) day period following the termination of employment or the relationship as a Director or Consultant, or (B) such longer period as may be agreed to by the Company and the Optionee
(for example, for purposes of satisfying the requirements of Section 1202(c)(3) of the Code (regarding "qualified small business stock")), and (iii) such right shall be exercisable only
for cash or cancellation of purchase money indebtedness for the shares. Should the right of repurchase be assigned by the Company, the assignee shall pay the Company cash equal to the difference
between the original purchase price and the stock's Fair Market Value if the original purchase price is less than the stock's Fair Market Value. 

        (j)    Right of Repurchase. The Option may, but need not, include a provision whereby the Company may elect, prior to the
Listing Date, to repurchase all or any part of the vested shares exercised pursuant to the Option; provided, however, that (i) such repurchase
right shall be exercisable only within (A) the one hundred and twenty (120) day period following the termination of employment or the relationship as a Director or Consultant, or
(B) such longer period as may be agreed to by the Company and the Optionee (for example, for purposes of satisfying the requirements of Section 1202(c)(3) of the Code (regarding
"qualified small business stock")), (ii) such repurchase right shall be exercisable for less than all of the vested shares only with the Optionee's consent, and (iii) such right shall be
exercisable only for cash or cancellation of purchase money indebtedness for the shares at a repurchase price equal to the greater of (A) the stock's Fair Market Value at the time of such
termination or (B) the original purchase price paid for such shares by the Optionee. Should the right of repurchase be assigned by the Company, the assignee shall pay the Company cash equal to
the difference between the original purchase price and the stock's Fair Market Value if the original purchase price is less than the stock's Fair Market Value. 

        (k)   Right of First Refusal. The Option may, but need not, include a provision whereby the Company may elect, prior to the
Listing Date, to exercise a right of first refusal following receipt of notice from the Optionee of the intent to transfer all or any part of the shares exercised pursuant to the Option. 

        (l)    Re-Load Options. Without in any way limiting the authority of the Board or Committee to make or not to make
grants of Options hereunder, the Board or Committee shall have the authority (but not an obligation) to include as part of any Option Agreement a provision entitling the Optionee to a further Option
(a "Re-Load Option") in the event the Optionee exercises the Option evidenced by the Option agreement, in whole or in part, by surrendering other shares of Common Stock in accordance with
this Plan and the terms and conditions of the Option Agreement. Any such Re-Load Option (i) shall be for a number of shares equal to the number of shares surrendered as part or all
of the exercise price of such Option; (ii) shall have an expiration date which is the same as the expiration date of the Option the exercise of which gave rise to such Re-Load
Option; and (iii) shall have an exercise price which is equal to one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Re-Load Option on the date of
exercise of the original Option. Notwithstanding the foregoing, a Re-Load Option which is granted to a 10% shareholder (as described in subsection 5(b)), shall have an exercise price which
is equal to one hundred ten percent (110%) of the Fair Market Value of the stock subject to the Re-Load Option on the date of exercise of the original Option and shall have a term which is
no longer than five (5) years. 

        Any
such Re-Load Option may be an Incentive Stock Option or a Nonstatutory Stock Option, as the Board or Committee may designate at the time of the grant of the original
Option; provided, however, that the designation of any Re-Load Option as an Incentive Stock Option shall be subject to the one hundred
thousand dollar ($100,000) annual limitation on exercisability of Incentive Stock Options described in subsection 12(e) of the Plan and in Section 422(d) of the Code. There shall be no
Re-Load Options on a Re-Load Option. Any such Re-Load Option shall be subject to the availability of sufficient shares under subsection 4(a) and the limits on the
grants of Options under subsection 5(c) 

and
shall be subject to such other terms and conditions as the Board or Committee may determine which are not inconsistent with the express provisions of the Plan regarding the terms of Options. 

 
 

7. Terms of Stock Bonuses and Purchases of Restricted Stock.    
    

        Each stock bonus or restricted stock purchase agreement shall be in such form and shall contain such terms and conditions as the Board or the Committee shall deem
appropriate. The terms and conditions of stock bonus or restricted stock purchase agreements may change from time to time, and the terms and conditions of separate agreements need not be identical,
but each stock bonus or restricted stock purchase agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following
provisions as appropriate: 

        (a)   Purchase Price. The purchase price under each restricted stock purchase Stock Award Agreement shall be such amount as the
Board or Committee shall determine and designate in such agreement, but in no event shall the purchase price be less than eighty-five percent (85%) of the stock's Fair Market Value on the
date such award is made. Notwithstanding the foregoing, the Board or the Committee may determine that eligible participants in the Plan may be awarded stock pursuant to a stock bonus agreement in
consideration for past services actually rendered to the Company or for its benefit. 

        (b)   Transferability. Rights under a stock bonus or restricted stock purchase agreement shall be transferable by the grantee
only upon such terms and conditions as are set forth in the applicable Stock Award Agreement, as the Board or the Committee shall determine in its discretion, so long as stock awarded under such Stock
Award Agreement remains subject to the terms of the agreement. 

        (c)   Consideration. The purchase price of stock acquired pursuant to a stock purchase agreement shall be paid either:
(i) in cash at the time of purchase; (ii) at the discretion of the Board or the Committee, according to a deferred payment or other arrangement with the person to whom the stock is sold;
or (iii) in any other form of legal consideration that may be acceptable to the Board or the Committee in its discretion. Notwithstanding the foregoing, the Board or the Committee to which
administration of the Plan has been delegated may award stock pursuant to a stock bonus agreement in consideration for past services actually rendered to the Company or for its benefit. 

        (d)   Vesting. Shares of stock sold or awarded under the Plan may, but need not, be subject to a repurchase option in favor of
the Company in accordance with a vesting schedule to be determined by the Board or the Committee. The applicable agreement shall provide that (i) the right to repurchase at the original
purchase price shall lapse at a minimum rate of twenty percent (20%) per year over five (5) years from the date the Stock Award was granted, and (ii) such right shall be exercisable only
(A) within the one hundred and twenty (120) day period following the termination of employment or the relationship as a Director or Consultant, or (B) such longer period as may be
agreed to by the Company and the holder of the Stock Award (for example, for purposes of satisfying the requirements of Section 1202(c)(3) of the Code (regarding "qualified small business
stock")), and (iii) such right shall be exercisable only for cash or cancellation of purchase money indebtedness for the shares. 

        (e)   Termination of Employment or Relationship as a Director or Consultant. In the event a Participant's Continuous Status as
an Employee, Director or Consultant terminates, the Company may repurchase or otherwise reacquire, subject to the limitations described in subsection 7(d), any or all of the shares of stock held by
that person which have not vested as of the date of termination under the terms of the stock bonus or restricted stock purchase agreement between the Company and such person. 

 
 

8. Stock Appreciation Rights.    
    

        (a)   The Board or Committee shall have full power and authority, exercisable in its sole discretion, to grant Stock
Appreciation Rights under the Plan to Employees or Directors of or Consultants to the Company or its Affiliates. To exercise any outstanding Stock Appreciation Right, the holder must 

provide
written notice of exercise to the Company in compliance with the provisions of the Stock Award Agreement evidencing such right. Except as provided in subsection 5(c), no limitation shall exist
on the aggregate amount of cash payments the Company may make under the Plan in connection with the exercise of a Stock Appreciation Right. 

        (b)   Three types of Stock Appreciation Rights shall be authorized for issuance under the Plan: 

        (1)   Tandem Stock Appreciation Rights. Tandem Stock Appreciation Rights will be granted appurtenant to an Option, and shall,
except as specifically set forth in this Section 8, be subject to the same terms and conditions applicable to the particular Option grant to which it pertains. Tandem Stock Appreciation Rights
will require the holder to elect between the exercise of the underlying Option for shares of stock and the surrender, in whole or in part, of such Option for an appreciation distribution. The
appreciation distribution payable on the exercised Tandem Right shall be in cash (or, if so provided, in an equivalent number of shares of stock based on Fair Market Value on the date of the Option
surrender) in an amount up to the excess of (A) the Fair Market Value (on the date of the Option surrender) of the number of shares of stock covered by that portion of the surrendered Option in
which the Optionee is vested over (B) the aggregate exercise price payable for such vested shares. 

        (2)   Concurrent Stock Appreciation Rights. Concurrent Rights will be granted appurtenant to an Option and may apply to all or
any portion of the shares of stock subject to the underlying Option and shall, except as specifically set forth in this Section 8, be subject to the same terms and conditions applicable to the
particular Option grant to which it pertains. A Concurrent Right shall be exercised automatically at the same time the underlying Option is exercised with respect to the particular shares of stock to
which the Concurrent Right pertains. The appreciation distribution payable on an exercised Concurrent Right shall be in cash (or, if so provided, in an equivalent number of shares of stock based on
Fair Market Value on the date of the exercise of the Concurrent Right) in an amount equal to such portion as shall be determined by the Board or the Committee at the time of the grant of the excess of
(A) the aggregate Fair Market Value (on the date of the exercise of the Concurrent Right) of the vested shares of stock purchased under the underlying Option which have Concurrent Rights
appurtenant to them over (B) the aggregate exercise price paid for such shares. 

        (3)   Independent Stock Appreciation Rights. Independent Rights will be granted independently of any Option and shall, except
as specifically set forth in this Section 8, be subject to the same terms and conditions applicable to Nonstatutory Stock Options as set forth in Section 6. They shall be denominated in
share equivalents. The appreciation distribution payable on the exercised Independent Right shall be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on
the date of the exercise of the Independent Right) of a number of shares of Company stock equal to the number of share equivalents in which the holder is vested under such Independent Right, and with
respect to which the holder is exercising the Independent Right on such date, over (B) the aggregate Fair Market Value (on the date of the grant of the Independent Right) of such number of
shares of Company stock. The appreciation distribution payable on the exercised Independent Right shall be in cash or, if so provided, in an equivalent number of shares of stock based on Fair Market
Value on the date of the exercise of the Independent Right. 

 
 

9. Cancellation and Re-Grant of Options.    
    

        (a)   The Board or the Committee shall have the authority to effect, at any time and from time to time, (i) the
repricing of any outstanding Options and/or any Stock Appreciation Rights under the Plan and/or (ii) with the consent of the affected holders of Options and/or Stock Appreciation Rights, the
cancellation of any outstanding Options and/or any Stock Appreciation Rights under the Plan and the grant in substitution therefor of new Options and/or Stock Appreciation Rights under the Plan
covering the same or different numbers of shares of stock, but having an exercise price per share not less than eighty-five percent (85%) of the Fair Market Value (one hundred percent
(100%) of the Fair Market 

Value
in the case of an Incentive Stock Option) or, in the case of a 10% shareholder (as described in subsection 5(b)), not less than one hundred ten percent (110%) of the Fair Market Value) per share
of stock on the new grant date. Notwithstanding the foregoing, the Board or the Committee may grant an Option and/or Stock Appreciation Right with an exercise price lower than that set forth above if
such Option and/or Stock Appreciation Right is granted as part of a transaction to which section 424(a) of the Code applies. 

        (b)   Shares subject to an Option or Stock Appreciation Right canceled under this Section 9 shall continue to be counted
against the maximum award of Options and Stock Appreciation Rights permitted to be granted pursuant to subsection 5(c) of the Plan. The repricing of an Option and/or Stock Appreciation Right under
this Section 9, resulting in a reduction of the exercise price, shall be deemed to be a cancellation of the original Option and/or Stock Appreciation Right and the grant of a substitute Option
and/or Stock Appreciation Right; in the event of such repricing, both the original and the substituted Options and Stock Appreciation Rights shall be counted against the maximum awards of Options and
Stock Appreciation Rights permitted to be granted pursuant to subsection 5(c) of the Plan. The provisions of this subsection 9(b) shall be applicable only to the extent required by
Section 162(m) of the Code. 

 
 

10. Covenants of the Company.    
    

        (a)   During the terms of the Stock Awards, the Company shall keep available at all times the number of shares of stock
required to satisfy such Stock Awards. 

        (b)   The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to issue and sell shares of stock upon exercise of the Stock Award; provided, however, that this undertaking shall not require the Company to register under the Securities
Act either the Plan, any Stock Award or any stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission
or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue
and sell stock upon exercise of such Stock Awards unless and until such authority is obtained. 

 
 

11. Use of Proceeds from Stock.    
    

        Proceeds from the sale of stock pursuant to Stock Awards shall constitute general funds of the Company. 

 
 

12. Miscellaneous.    
    

        (a)   The Board shall have the power to accelerate the time at which a Stock Award may first be exercised or the time during
which a Stock Award or any part thereof will vest pursuant to subsection 6(e), 7(d) or 8(b), notwithstanding the provisions in the Stock Award stating the time at which it may first be exercised or
the time during which it will vest. 

        (b)   Neither an Employee, Director or Consultant nor any person to whom a Stock Award is transferred under subsection 6(d),
7(b), or 8(b) shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to such Stock Award unless and until such person has satisfied all
requirements for exercise of the Stock Award pursuant to its terms. 

        (c)   Nothing in the Plan or any instrument executed or Stock Award granted pursuant thereto shall confer upon any Employee,
Director, Consultant or other holder of Stock Awards any right to continue in the employ of the Company or any Affiliate (or to continue acting as a Director or Consultant) or shall affect the right
of the Company or any Affiliate to terminate the employment of any Employee with or without cause, the right of the Company's Board of Directors and/or the Company's shareholders to remove any
Director as provided in the Company's By-Laws and the 

provisions
of the Delaware General Corporation Law, or the right to terminate the relationship of any Consultant subject to the terms of such Consultant's agreement with the Company or Affiliate. 

        (d)   To the extent that the aggregate Fair Market Value (determined at the time of grant) of stock with respect to which
Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year under all plans of the Company and its Affiliates exceeds one hundred thousand dollars ($100,000),
the Options or portions thereof which exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options. 

        (e)   The Company may require any person to whom a Stock Award is granted, or any person to whom a Stock Award is transferred
pursuant to subsection 6(d), 7(b) or 8(b), as a condition of exercising or acquiring stock under any Stock Award, (1) to give written assurances satisfactory to the Company as to such person's
knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and
business matters, and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Stock Award; and (2) to give written
assurances satisfactory to the Company stating that such person is acquiring the stock subject to the Stock Award for such person's own account and not with any present intention of selling or
otherwise distributing the stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (i) the issuance of the shares upon the exercise or
acquisition of stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act, or (ii) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to,
legends restricting the transfer of the stock. 

        (f)    To the extent provided by the terms of a Stock Award Agreement, the person to whom a Stock Award is granted may satisfy
any federal, state or local tax withholding obligation relating to the exercise or acquisition of stock under a Stock Award by any of the following means or by a combination of such means:
(1) tendering a cash payment; (2) authorizing the Company to withhold shares from the shares of the common stock otherwise issuable to the participant as a result of the exercise or
acquisition of stock under the Stock Award; or (3) delivering to the Company owned and unencumbered shares of the common stock of the Company. 

 
 

13. Adjustments upon Changes in Stock.    
    

        (a)   In the event of: 

        (1)   any
merger or consolidation (regardless of whether the Company is the surviving entity) except for a merger or consolidation for the sole purpose of changing the state
of incorporation of the Company and except for a merger or consolidation that does not result in the stockholders of the Company before such event retaining, directly or indirectly, less than a
majority of the voting stock of the surviving or resulting corporation; 

        (2)   a
sale of all or substantially all of the assets of the Company; or 

        (3)   any
other capital reorganization in which more than fifty percent (50%) of the shares of the Company entitled to vote are exchanged except for a reorganization that does
not result in the stockholders of the Company before such event retaining, directly or indirectly, less than a majority of the voting stock of the reorganized corporation 

        (each
of (1), (2) and (3) being a "Change in Control") then: (i) any surviving corporation shall assume any Stock Awards outstanding under the Plan or shall
substitute similar Stock Awards for those outstanding under the Plan, or (ii) such Stock Awards shall continue in full force and effect. In the event any surviving corporation refuses to assume
or continue such Stock Awards, or to substitute 

similar
stock awards for those outstanding under the Plan, then, with respect to Stock Awards held by persons then performing services as Employees, Directors or Consultants for the Company, the time
at which such Stock Awards may first be exercised shall be accelerated and the Stock Awards terminated if not exercised prior to such event. In addition, the Option may, but need not, include a
provision whereby the Option shall in any event be accelerated in full and become fully and immediately vested and exercisable immediately before the occurrence of a Change in Control. In the event of
a dissolution or liquidation of the Company, any Stock Awards outstanding under the Plan shall terminate if not exercised prior to such event. 

        (b)   In addition, with respect to any person who was providing Continuous Service as an Employee, Director or Consultant
immediately prior to the consummation of the Change in Control, any Stock Awards held by such person shall immediately become fully vested and exercisable (and any repurchase right by the Company with
respect to shares acquired by such person under an Option shall lapse) if such person is Involuntarily Terminated Without Cause or Constructively Terminated within eighteen (18) months
following the Change in Control. Notwithstanding the preceding sentence, in the event all of the following occurs: (i) such contemplated Change in Control would occur prior to the date two
(2) years following the adoption of this Section 13(b); (ii) such potential acceleration of vesting (and exercisability) would by
itself result in a contemplated Change in Control that would otherwise be eligible to be accounted for as a "pooling of interests" accounting transaction to become ineligible
for such accounting treatment; and (iii) the potential acquiror of the Company desires to account for such contemplated Change in Control as a "pooling of interests" transaction, then such
acceleration shall not occur unless otherwise expressly provided in an Option. Additionally, in the event that the restrictions upon acceleration provided for in the immediately preceding sentence  by itself would result in a contemplated Change in Control to become ineligible to be accounted for as a "pooling of interests" accounting transaction,
then such restrictions shall be deemed inoperative. Accounting issues shall be determined by the Company's independent public accountants applying generally accepted accounting principles. 

        For
purposes of the Plan, Constructively Terminated shall mean the voluntary termination of employment by Stock Award recipient after a reduction by the Company in Stock Award
recipient's base salary of fifteen percent (15%) or greater without Stock Award recipient's express written consent. 

        For
purposes of the Plan, Involuntarily Terminated Without Cause shall mean dismissal or discharge of Stock Award recipient for any reason other than Cause, death or Disability. 

        For
purposes of the Plan, Cause shall mean any of the following: (a) an intentional act which materially injures the Company; (b) an intentional refusal or failure to
follow lawful and reasonable directions of the Board or an individual to whom participant reports (as appropriate); (c) a willful and habitual neglect of duties; or (d) a conviction of a
felony involving moral turpitude which is reasonably likely to inflict or has inflicted material injury on the Company. 

 
 

14. Amendment of the Plan and Stock Awards.    
    

        (a)   The Board at any time, and from time to time, may amend the Plan. However, except as provided in Section 13
relating to adjustments upon changes in stock, no amendment shall be effective unless approved by the shareholders of the Company within twelve (12) months before or after the adoption of the
amendment, where the amendment will: 

        (1)   Increase the number of shares reserved for Stock Awards under the Plan; 

        (2)   Modify the requirements as to eligibility for participation in the Plan (to the extent such modification requires
shareholder approval in order for the Plan to satisfy the requirements of Section 422 of the Code); or 

        (3)   Modify the Plan in any other way if such modification requires shareholder approval in order for the Plan to satisfy the
requirements of Section 422 of the Code or to comply with the requirements of Rule 16b-3. 

        (b)   The Board may in its sole discretion submit any other amendment to the Plan for shareholder approval, including, but not
limited to, amendments to the Plan intended to satisfy the requirements of Section 162(m) of the Code and the regulations promulgated thereunder regarding the exclusion of performance-based
compensation from the limit on corporate deductibility of compensation paid to certain executive officers. 

        (c)   It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to
provide eligible Employees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to Incentive Stock Options and/or
to bring the Plan and/or Incentive Stock Options granted under it into compliance therewith. 

        (d)   Rights and obligations under any Stock Award granted before amendment of the Plan shall not be impaired by any amendment
of the Plan unless (i) the Company requests the consent of the person to whom the Stock Award was granted and (ii) such person consents in writing. 

        (e)   The Board at any time, and from time to time, may amend the terms of any one or more Stock Award; provided, however, that
the rights and obligations under any Stock Award shall not be impaired by any such amendment unless (i) the Company requests the consent of the person to whom the Stock Award was granted and
(ii) such person consents in writing. 

 
 

15. Termination or Suspension of the Plan.    
    

        (a)   The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate ten
(10) years from the date the Plan is adopted by the Board or approved by the shareholders of the Company, whichever is earlier. No Stock Awards may be granted under the Plan while the Plan is
suspended or after it is terminated. 

        (b)   Rights and obligations under any Stock Award granted while the Plan is in effect shall not be impaired by suspension or
termination of the Plan, except with the written consent of the person to whom the Stock Award was granted. 

 
 

16. Effective Date of Plan.    
    

        The Plan shall become effective as determined by the Board, but no Stock Awards granted under the Plan shall be exercised unless and until the Plan has been
approved by the shareholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board. 

  

 
 

PROS HOLDINGS, INC.
  1999 EQUITY INCENTIVE PLAN
  INCENTIVE STOCK OPTION GRANT    
    

                        ,
Optionee: 

        PROS
Holdings, Inc., a Delaware corporation (the "Company"), pursuant to its 1999 Equity Incentive Plan (the "Plan"), has granted to you, the Optionee named above, an option to
purchase shares of the common stock of the Company ("Common Stock"). This option is intended to qualify as an "incentive stock option" within the meaning of Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"). 

        The
grant hereunder is in connection with and in furtherance of the Company's compensatory benefit plan for participation of the Company's employees (including officers) directors or
consultants and is intended to comply with the provisions of Rule 701 promulgated by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Act"). Defined
terms not explicitly defined in this agreement but defined in the Plan shall have the same definitions as in the Plan. 

        The
details of your option are as follows: 

        1.     Total Number of Shares Subject to this Option.    The total number of shares of Common Stock subject to this
option is                        . 

        2.     Vesting.    Subject to the limitations contained herein, twenty-five percent (25%) of the shares
will vest (become exercisable) on                        , and the shares will then vest twenty-five percent (25%)
each                        thereafter until either (i) you cease to provide
services to the Company for any reason, or (ii) this option becomes fully vested. 

        3.     Exercise Price And Method Of Payment.

        (a)   Exercise Price.    The exercise price of this option
is                        ($            ) per share, being not
less than the fair market value of the Common Stock on the date of grant of this option. 

        (b)   Method of Payment.    Payment of the exercise price per share is due in full upon exercise of all or any part
of each installment which has accrued to you. You may elect, to the extent permitted by applicable statutes and regulations, to make payment of the exercise price under one of the following
alternatives: 

        (i)    Payment of the exercise price per share in cash (including check) at the time of exercise; 

        (ii)   Payment pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board which,
prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company
from the sales proceeds; 

        (iii) Provided that at the time of exercise the Company's Common Stock is publicly traded and quoted regularly in the Wall
Street Journal, payment by delivery of already-owned shares of Common Stock, held for the period required to avoid a charge to the Company's reported earnings, and owned free and clear of any liens,
claims, encumbrances or security interests, which Common Stock shall be valued at its fair market value on the date of exercise; or 

        (iv)  Payment by a combination of the methods of payment permitted by subparagraph 3(b)(i) through
3(b)(iii) above. 

1

 

        4.     Whole Shares.    This option may not be exercised for any number of shares which would require the issuance of
anything other than whole shares. 

        5.     Securities Law Compliance.    Notwithstanding anything to the contrary contained herein, this option may not be
exercised unless the shares issuable upon exercise of this option are then registered under the Act or, if such shares are not then so registered, the Company has determined that such exercise and
issuance would be exempt from the registration requirements of the Act. 

        6.     Term.    The term of this option commences
on                        , the date of grant, and expires
on                        
(the "Expiration Date," which date shall be no more than ten (10) years from the date this option is granted), unless this option expires sooner as set forth below or in the Plan. In no event
may this option be exercised on or after the Expiration Date. This option shall terminate prior to the Expiration Date as follows: three (3) months after the termination of your Continuous
Status as an Employee, Director or Consultant with the Company or an Affiliate of the Company unless one of the following circumstances exists: 

        (a)   Your termination of Continuous Status as an Employee, Director, or Consultant is due to your disability (within the
meaning of Section 422(c)(6) of the Code). This option will then expire on the earlier of the Expiration Date set forth above or twelve (12) months following such termination of
Continuous Status as an Employee, Director or Consultant. 

        (b)   Your termination of Continuous Status as an Employee, Director or Consultant is due to your death or your death occurs
within three (3) months following your termination of Continuous Status as an Employee, Director or Consultant for any other reason. This option will then expire on the earlier of the
Expiration Date set forth above or six (6) months after your death. 

        (c)   If during any part of such three (3) months period you may not exercise your option solely because of the
condition set forth in paragraph 5 above, then your option will not expire until the earlier of the Expiration Date set forth above or until this option shall have been exercisable for an
aggregate period of three (3) months after your termination of the Continuous Status as an Employee, Director, or Consultant. 

        (d)   If your exercise of the option within three (3) months after termination of your Continuous Status as an Employee,
Director, or Consultant with the Company or with an Affiliate of the Company would result in liability under section 16(b) of the Securities Exchange Act of 1934, then your option will expire
on the earlier of (i) the Expiration Date set forth above, (ii) the tenth (10th) day after the last date upon which exercise would result in such liability or (iii) six
(6) months and ten (10) days after the termination of your Continuous Status as an Employee, Director or Consultant with the Company or an Affiliate of the Company. 

        However,
this option may be exercised following termination of Continuous Status as an Employee, Director or Consultant only as to that number of shares as to which it was exercisable on
the date of termination of Continuous Status as an Employee, Director or Consultant under the provisions of paragraph 2 of this option. 

        In
order to obtain the federal income tax advantages associated with an "incentive stock option," the Code requires that at all times beginning on the date of grant of the option and
ending on the day three (3) months before the date of the option's exercise, you must be an employee of the Company or an Affiliate of the Company, except in the event of your death or
permanent and total disability. The Company has provided for continued vesting or extended exercisability of your option under certain circumstances for your benefit, but cannot guarantee that your
option will necessarily be treated as an "incentive stock option" if you provide services to the Company or an Affiliate of the Company as a consultant or exercise your option more than three
(3) months after the date your employment with the Company and all Affiliates of the Company terminates. 

2

 

        7.     Exercise.

        (a)   This option may be exercised, to the extent specified above, by delivering a notice of exercise (in a form designated by
the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional
documents as the Company may then require pursuant to subsection 12(e) of the Plan. 

        (b)   By exercising this option, you agree that: 

        (i)    as a precondition to the completion of any exercise of this option, the Company may require you to enter an arrangement
providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of this option; (2) the lapse of any substantial
risk of forfeiture to which the shares are subject at the time of exercise; or (3) the disposition of shares acquired upon such exercise; 

        (ii)   you will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the
shares of the Common Stock issued upon exercise of this option that occurs within two (2) years after the date of this option grant or within one (1) year after such shares of Common
Stock are transferred upon exercise of this option; and 

        (iii) the Company (or a representative of the underwriters) may, in connection with the first underwritten registration of
the offering of any securities of the Company under the Act, require that you not sell or otherwise transfer or dispose of any shares of Common Stock or other securities of the Company during such
period (not to exceed one hundred eighty (180) days) following the effective date (the "Effective Date") of the registration statement of the Company filed under the Act as may be requested by
the Company or the representative of the underwriters. You further agree that the
Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such period. 

        8.     Right of Repurchase; Right of First Refusal.

        (a)   The Company may elect, prior to the Listing Date, to repurchase all or any part of the vested shares exercised pursuant
to the Option; provided, however, that (i) such repurchase right shall be exercisable only within (A) the one hundred and twenty
(120) day period following the termination of employment or the relationship as a Director or Consultant, or (B) such longer period as may be agreed to by the Company and the Optionee
(for example, for purposes of satisfying the requirements of Section 1202(c)(3) of the Code (regarding "qualified small business stock")), (ii) such repurchase right shall be exercisable
for less than all of the vested shares only with the Optionee's consent, and (iii) such right shall be exercisable only for cash or cancellation of purchase money indebtedness for the shares at
a repurchase price equal to the greater of (A) the stock's Fair Market Value at the time of such termination or (B) the original purchase price paid for such shares by the Optionee. Such
right of repurchase may be assigned by the Company. 

        (b)   If the Company does not elect to exercise its right of repurchase under Section 8(a) above, and at any time
thereafter but prior to the Listing Date the Optionee (including any permitted transferee of the Optionee's shares under Section 8(c)) receives a bona fide offer to purchase all or any of the
vested shares exercised pursuant to the Option (the "Offer") from a third party other than a permitted transferee of his shares under Section 8(c) (the "Offeror") 

3

 

which
the Optionee wishes to accept, the Optionee may transfer such shares pursuant to and in accordance with the following provisions: 

        (i)    the Optionee shall cause the Offer to be reduced to writing and shall notify the Company in writing of his or her desire
to accept the Offer and otherwise comply with the provisions of this Section 8(b). The Optionee's notice shall constitute an irrevocable offer to sell such shares to the Company at a price
equal to the price contained in, and on the same terms and conditions of, the Offer. The notice shall be accompanied by a true copy of the Offer (which shall identify the Offeror). 

        (ii)   the Company shall have the right to offer to purchase all, but not less than all, of the shares covered by the Offer. To
exercise such right, the Company shall, within fifteen (15) days of receipt of such written notice, communicate in writing such election to the Optionee. Such written election to purchase shall
constitute a valid, legally binding and enforceable agreement for the sale and purchase of all of the shares covered by the Offer. 

        (c)   Permitted transfers by an Optionee are (i) transfers to the Optionee's spouse or children, to a trust of which the
Optionee is the settlor or a trustee for the benefit of his spouse or children, and (ii) transfers upon an Optionee's death to his heirs, executors or administrators or to a trust under his or
her will or to his or her guardian or conservator, provided that in any such case the transferee shall have entered into an enforceable written agreement providing that all shares so transferred shall
continue to be subject to the provisions of Section 8(b) and (c) as if such shares were still held by the Optionee, and provided further that such permitted transferee shall not be
permitted to make any further transfers without complying with the provisions of Section 8(b) and (c). Anything to the contrary herein notwithstanding, transferees permitted by this
Section 8(c) shall take any shares so transferred subject to all obligations under Section 8(b) and (c) as if such shares were still held by the Optionee whether or not such
transferees so expressly agree. 

        9.     Transferability.    This option is not transferable, except by will or by the laws of descent and distribution,
and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who,
in the event of your death, shall thereafter be entitled to exercise this option. 

        10.   Option Not a Service Contract.    This option is not an employment contract and nothing in this option shall be
deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company, or of the Company to continue your employment with the Company. In addition, nothing in
this option shall obligate the Company or any Affiliate of the Company, or their respective stockholders, Board of Directors, officers or employees to continue any relationship which you might have as
a Director or Consultant for the Company or Affiliate of the Company. 

        11.   Notices.    Any notices provided for in this option or the Plan shall be given in writing and shall be deemed
effectively given upon receipt or, in the case of notices delivered by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the
address specified below or at such other address as you hereafter designate by written notice to the Company. 

        12.   Governing Plan Document.    This option is subject to all the provisions of the Plan, a copy of which is
attached hereto and its provisions are hereby made a part of this option, including without limitation the provisions of Section 6 of the Plan relating to option provisions, and is further
subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of
this option and those of the Plan, the provisions of the Plan shall control.

        By
this exercise, I agree (i) to provide such additional documents as you may require pursuant to the terms of the 1999 Equity Incentive Plan, (ii) to provide for the
payment by me to you (in the manner designated by you) of your withholding obligation, if any, relating to the exercise of this option, and (iii) if this exercise relates to an incentive stock
option, to notify you in writing within fifteen (15) days after the date of any disposition of any of the shares of Common Stock issued upon exercise of this option that occurs within two
(2) years after the date of grant of this option or within one (1) year after such shares of Common Stock are issued upon exercise of this option. 

        I
hereby make the following certifications and representations with respect to the number of shares of Common Stock of the Company listed above (the "Shares"), which are being acquired
by me for my own account upon exercise of the Option as set forth above: 

        I
acknowledge that the Shares have not been registered under the Securities Act of 1933, as amended (the "Act"), and are deemed to constitute "restricted securities" under
Rule 701 and "control securities" under Rule 144 promulgated under the Act. I warrant and represent to the Company that I have no present intention of distributing or selling said
Shares, except as permitted under the Act and any applicable state securities laws. 

        I
further acknowledge that I will not be able to resell the Shares for at least ninety days after the stock of the Company becomes publicly traded (i.e., subject to the reporting
requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934) under Rule 701 and that more restrictive conditions apply to affiliates of the Company under Rule 144. 

        I
further acknowledge and agree that under the provisions of the Option, the Company may elect, prior to the first date upon which any security of the Company is listed (or approved for
listing) upon notice of issuance on any securities exchange, or designated (or approved for designation) upon notice of issuance as a national market security on an interdealer quotation system (the
"Listing Date"), to repurchase all or any part of the Shares on the terms and conditions provided in the Option and that

such
right of repurchase may be assigned by the Company. I further acknowledge and agree that if the Company does not elect to exercise such right of repurchase, and at any time thereafter but prior
to the Listing Date, I (including any permitted transferee of the Shares under the provisions of the Option) receive a bona fide offer to purchase all or any of the Shares from a third party (other
than such a permitted transferee) which I wish to accept, I may only transfer such Shares pursuant to and in accordance with the provisions of the Option which provide the Company with a right of
first refusal. 

        I
further acknowledge that all certificates representing any of the Shares subject to the provisions of the Option shall have endorsed thereon appropriate legends reflecting the
foregoing limitations, as well as any legends reflecting restrictions pursuant to the Company's Articles of Incorporation, Bylaws, and/or applicable securities laws. 

        I
further agree that, if required by the Company (or a representative of the underwriters) in connection with the first underwritten registration of the offering of any securities of the
Company under the Act, I will not sell or otherwise transfer or dispose of any shares of Common Stock or other securities of the Company during such period (not to exceed one hundred eighty
(180) days) following the effective date of the registration statement of the Company filed under the Act (the "Effective Date") as may be requested by the Company or the representative of the
underwriters. I further agree that the Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such period. 

	 	 	Very truly yours,
