Section 2.1.          Grant of Options.  The Committee may from time to time grant Options to Eligible Persons.  Options may be Incentive Stock Options or Nonincentive Stock Options as designated by the Committee on or before the Date of Grant.  If no such designation is made by the Committee for an Option, the Option shall be a Nonincentive Stock Option.  The aggregate Fair Market Value (determined as of the Date of Grant) of the Shares with respect to which Incentive Stock Options are exercisable for the first time by an Optionee during any calendar year under the Plan and all such plans of the Company and any parent or Subsidiary of the Company (as defined in Section 424 of the Code) shall not exceed $100,000.

Section 2.3.          Term of Option.  The term of an Option shall be determined by the Committee, provided that, in the case of an Incentive Stock Option, if the grant is to a person who owns directly or indirectly (within the meaning of Section 422(b)(6) of the Code) stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, the term of the Option shall not exceed five years from the Date of Grant.  Notwithstanding any other provision of this Plan, no Option shall be exercised after the expiration of its term.

Section 2.4.          Vesting.  Options shall be exercisable at such times and subject to such terms and conditions as the Committee shall specify in the option agreement.  Unless the option agreement specifies otherwise, the Committee shall have discretion at any time to accelerate such times and otherwise waive or amend any conditions in respect of all or any portion of any Options.  Notwithstanding the other provisions of this Section 2.4 and unless otherwise provided in the option agreement, in the event that an Optionee’s employment is terminated without Cause by the Company, a Subsidiary or successor entity, or is terminated by the Optionee for Good Reason, in either case in connection with or within 18 months after a Change in Control, all Options held by the Optionee immediately prior to such termination shall become immediately exercisable.

Section 2.5.          Termination of Options.

(a)          Except as otherwise provided in the Plan or the option agreement, the portion of an Option that is exercisable shall automatically and without notice terminate upon the earliest to occur of the following:

(c)          The Committee shall have discretion at any time to extend the term of any Nonincentive Stock Option to any date that is not later than the date described in Section 2.5(a)(v).

Section 2.6.          Exercise of Options.  An Option may be exercised in whole or in part to the extent exercisable in accordance with Section 2.4 and the option agreement.  An Option shall be deemed exercised when (i) the Company has received written notice of such exercise in accordance with the terms of the Option and (ii) full payment of the aggregate exercise price of the Shares as to which the Option is exercised has been made.  Unless further limited by the Committee for any Option, the exercise price of any Shares purchased shall be paid solely in cash, by certified or cashier's check, by money order, by personal check, by withholding Shares from an Award or with Shares owned by the Optionee for at least six months, or by a combination of the foregoing.  If the exercise price is paid in whole or in part with Shares, the value of the Shares withheld shall be their Fair Market Value on the date received by the Company.  An Optionee may elect to have Shares withheld to satisfy federal or state income tax withholding requirements applicable upon the exercise of an Option.

Section 2.7.          Corporate Transactions.

(a)           In the event of a merger, consolidation or other reorganization of the Company in which the Company is not the surviving entity, the Board or the Committee may provide for payment in cash or in securities of the Company or the surviving entity in lieu of and in complete satisfaction of Options.

(b)           Except as otherwise expressly provided herein, the issuance by the Company of shares of its capital stock of any class, or securities convertible into shares of capital stock of any class, either in connection with direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of or exercise price of Shares then subject to outstanding Options granted under the Plan.

(c)           Without limiting the generality of the foregoing, the existence of outstanding Options granted under the Plan shall not affect in any manner the right or power of the Company to make, authorize or consummate (i) any or all adjustments, recapitalizations, reorganizations or other changes in the Company's capital structure or its business; (ii) any merger or consolidation of the Company; (iii) any issue by the Company of debt securities, or preferred or preference stock that would rank above the Shares subject to outstanding Options; (iv) the dissolution or liquidation of the Company; (v) any sale, transfer or assignment of all or any part of the assets or business of the Company; or (vi) any other corporate act or proceeding, whether of a similar character or otherwise.

Section 2.8.          Issuance of Shares.  No person shall be, or have any of the rights or privileges of, a stockholder of the Company with respect to any of the Shares subject to any Option unless and until such Shares (whether represented by certificates or in book-entry or other electronic form) shall have been issued and delivered to such person.

Section 3.1.          Grant of Restricted Stock Awards.  The Committee may from time to time grant Restricted Stock Awards to Eligible Persons.

Section 3.2.          Terms and Conditions of Restricted Stock Awards.  Each Restricted Stock Award shall specify the number of shares of Restricted Stock awarded, the price, if any, to be paid by the Participant receiving the Restricted Stock Award, the date or dates on which the Restricted Stock will vest and any other terms and conditions that the Committee may determine.  The vesting and number of shares of Restricted Stock may be conditioned upon the completion of a specified period of service with the Company or its Subsidiaries or upon the attainment of any performance goals established by the Committee, including without limitation goals related to the performance of the Company or any Subsidiary, division, department or other unit of the Company, the performance of the Company’s common stock or other securities, the performance of the recipient of the Restricted Stock Award or any combination of the foregoing.  A Participant may elect to have Shares withheld from a Restricted Stock Award to satisfy federal or state income tax withholding requirements applicable upon the vesting of Restricted Stock.

Section 3.3.          Restrictions on Transfer.  Unless otherwise provided in the grant relating to a Restricted Stock Award, the Restricted Stock granted to a Participant (whether represented by certificates or in book-entry or other electronic form) shall be registered in the Participant's name or, at the option of the Committee, not issued until such time as the Restricted Stock shall become vested or as otherwise determined by the Committee.  If certificates are issued prior to the shares of Restricted Stock becoming vested, such certificates shall either be held by the Company on behalf of the Participant, or delivered to the Participant bearing a legend to restrict transfer of the certificate until the Restricted Stock has vested, as determined by the Committee.  The Committee shall determine whether the Participant shall have the right to vote and/or receive dividends on the Restricted Stock before it has vested.  Except as may otherwise be expressly permitted by the Committee, no share of Restricted Stock may be sold, transferred, assigned or pledged by the Participant until such share has vested in accordance with the terms of the Restricted Stock Award.  Except as provided in Section 3.4 or unless the grant of a Restricted Stock Award specifies otherwise, in the event that a Participant ceases to be an Employee before all the Participant's Restricted Stock has vested, or in the event other conditions to the vesting of Restricted Stock have not been satisfied prior to any deadline for the satisfaction of such conditions set forth in the award agreement, the shares of Restricted Stock that have not vested shall be forfeited and any purchase price paid by the Participant for the forfeited Shares shall be returned to the Participant.  At the time Restricted Stock vests (and, if the Participant has been issued legended certificates for Restricted Stock, upon the return of such certificates to the Company), such vested shares shall be issued to the Participant (or the beneficiary designated by the Participant in the event of death), in certificated or book entry or other electronic form, free of all restrictions.

Section 3.4.          Accelerated Vesting.  Notwithstanding the vesting conditions set forth in a Restricted Stock Award, unless the Restricted Stock Award grant or other agreement with the Participant specifies otherwise:

(a)           the Committee may in its discretion at any time accelerate the vesting of Restricted Stock or otherwise waive or amend any conditions of a grant of a Restricted Stock Award, and

(b)           in the event that a Participant’s employment is terminated without Cause by the Company, a Subsidiary or successor, or is terminated by the Participant for Good Reason, in either case in connection with or within 18 months after a Change in Control, all shares of Restricted Stock held by the Participant immediately prior to such termination shall immediately become vested.

Section 3.5.          Section 83(b) Election.  If a Participant receives Restricted Stock that is subject to a “substantial risk of forfeiture,” such Participant may elect under Section 83(b) of the Code to include in his or her gross income, for the taxable year in which the Restricted Stock is received, the excess of the Fair Market Value of such Restricted Stock on the Date of Grant (determined without regard to any restriction other than one which by its terms will never lapse), over the amount paid for the Restricted Stock.  If the Participant makes the Section 83(b) election, the Participant shall (a) make such election in a manner that is satisfactory to the Committee, (b) provide the Company with a copy of such election, (c) agree to notify the Company promptly if any Internal Revenue Service or state tax agent, on audit or otherwise, questions the validity or correctness of such election or of the amount of income reportable on account of such election and (d) agree to such federal and state income tax withholding as the Committee may reasonably require in its sole discretion.

Section 4.1.          Terms and Conditions of Performance Awards.  The Committee may from time to time grant Awards that are intended to be “performance-based compensation,” which are payable in stock, cash or a combination thereof, at the discretion of the Committee.

(a)           Performance Period.  The Committee shall establish a Performance Period for each Performance Award at the time such Performance Award is granted.  A Performance Period may overlap with Performance Periods relating to other Performance Awards granted hereunder to the same Participant.  The Committee shall not grant Performance Awards to Section 162(m) Participants after the earliest to occur of (i) the 90^th day after the start of the Performance Period, (ii) the date on which 25% of the Performance Period has elapsed or (iii) the date on which the satisfaction of the Performance Objectives becomes substantially certain.

(b)           Performance Objectives.  The Committee shall establish written performance objectives for the Participant at the time of the grant of each Performance Award.  Each Performance Award shall be contingent upon the achievement of the Performance Objectives established by the Committee.  Performance Objectives shall be based on earnings, cash flow, economic value added, total stockholder return, return on equity, return on capital, return on assets, revenues, operating profit, EBITDA, net profit, earnings per share, stock price, cost reduction goals, debt to capital ratio, financial return ratios, profit or operating margins, working capital or any combination of the foregoing, for the Company on a consolidated basis or, if applicable, for one or more Subsidiaries, divisions, departments or other units of the Company or one or more of its Subsidiaries.

(c)           Amount; Frequency.  The Committee shall determine at the time of grant of Performance Awards the target and maximum values of Performance Awards and the date or dates when Performance Awards are earned.

(d)           Payment.  Following the end of each Performance Period, the holder of each Performance Award will be entitled to receive payment of an amount, not exceeding the maximum value of the Performance Award, based on the achievement of the Performance Objectives for such Performance Period, as determined in writing by the Committee. Unless otherwise provided in the Performance Award, if the Participant exceeds the specified minimum level of acceptable achievement but does not attain the Performance Objectives, the Participant shall be deemed to have partly earned the Performance Award, and shall become entitled to receive a portion of the total award, as determined by the Committee.  Unless otherwise provided in the Performance Award, if a Performance Award is granted after the start of a Performance Period, the Performance Award shall be reduced to reflect the portion of the Performance Period during which the Performance Award was in effect.

(e)           Termination of Employment.  Unless otherwise provided in the Performance Award, a Participant who receives a Performance Award and who ceases to be an Employee as a result of death, Disability or retirement before the end of the applicable Performance Period shall be entitled to receive, to the extent earned as a result of the full or partial achievement of the Performance Objectives during the Performance Period, a portion of the Performance Award that is proportional to the portion of the Performance Period during which the Participant was employed, with payment to be made following the end of the Performance Period.  Unless otherwise provided in the Performance Award, a Participant who receives a Performance Award who ceases to be an Employee for any reason other than death, Disability or retirement shall not be entitled to any part of the Performance Award.

(f)            Accelerated Vesting.  Notwithstanding the vesting conditions set forth in a Performance Award, unless the Performance Award specifies otherwise (i) the Committee may in its discretion at any time accelerate the time at which the Performance Award is considered to have been earned or otherwise waive or amend any conditions (including but not limited to Performance Objectives) in respect of a Performance Award, and (ii) all Performance Awards shall be considered earned upon a Change in Control of the Company.  In addition, upon a Change in Control of the Company, unless a Performance Award specifies otherwise, each Participant shall receive the target Performance Award such Participant could have earned for the proportionate part of the Performance Period prior to the Change in Control, and shall retain the right to earn any additional portion of his or her Performance Award if such Participant remains in the Company's employ through the end of the Performance Period.

(g)           Stockholder Rights.  The holder of a Performance Award shall, as such, have none of the rights of a stockholder of the Company.

(h)           Annual Incentive Plan.  Cash awards based on the attainment of the performance objectives established under the Company’s Annual Incentive Plan may, in the Committee’s discretion, be considered Performance Awards granted under the Plan, provided that such awards are subject to the terms and conditions of this Article IV.

Section 5.1.          Administration of the Plan.  The Plan shall be administered by the Committee.  The Committee shall have the authority to interpret the provisions of the Plan, to adopt such rules and regulations for carrying out the Plan as it may deem advisable, to decide conclusively all questions arising with respect to the Plan, to establish performance criteria in respect of Awards under the Plan, to determine whether Plan requirements have been met for any Participant in the Plan and to make all other determinations and take all other actions necessary or desirable for the administration of the Plan.  All decisions and acts of the Committee shall be final and binding upon all affected Participants.  If there is no Committee, the Board shall administer the Plan and in such case all references to the Committee shall be deemed to be references to the Board.

Section 5.2.          Adjustments for Changes in Capitalization.  In the event of any (a) stock dividends, stock splits, recapitalizations, combinations, exchanges of shares, mergers, consolidations, liquidations, split-ups, split-offs, spin-offs or other similar changes in capitalization, (b) distributions to stockholders, including a rights offering, other than regular cash dividends, (c) changes in the outstanding stock of the Company by reason of any increase or decrease in the number of issued Shares resulting from a split-up or consolidation of Shares or any similar capital adjustment or the payment of any stock dividend, (d) Share repurchase at a price in excess of the market price of the Shares at the time such repurchase is announced or (e) other similar increase or decrease in the number of the Shares, the Committee, in its sole discretion, shall make appropriate adjustment in the number and kind of shares authorized by the Plan in the number, price or kind of shares covered by the Awards and in any outstanding Awards under the Plan.  In addition, upon the occurrence of any event described in this Section 5.2, the Committee, in its sole discretion, shall make appropriate adjustment in the limits specified in Section 1.3(b), (c) and (d) so that the effect of such limits is, as nearly as practicable, equivalent to the effect of such limits prior to the event in question, provided that any such adjustment complies with applicable laws and does not cause an award that is intended to satisfy the performance-based compensation exception under Section 162(m) of the Code to fail to satisfy the exception.  In the event of any adjustment in the number of Shares covered by any Award, any fractional Shares resulting from such adjustment shall be disregarded and each such Award shall cover only the number of full Shares resulting from such adjustment.

Section 5.3.          Amendment.

(a)           The Board may amend or modify the Plan in any respect at any time, subject to stockholder approval if required by applicable law or regulation or by applicable stock exchange rules.  Such action shall not impair any of the rights of any Participant with respect to any Award outstanding on the date of the amendment or modification without the Participant’s written consent.

(b)           The Committee shall have the authority to amend any Award to include any provision which, at the time of such amendment, is authorized under the terms of the Plan; however, no outstanding Award may be revoked or altered in a manner unfavorable to the Participant without the written consent of the Participant.

Section 5.4.          Transferability of Awards.  An Award shall not be transferable by the Participant otherwise than by will or the laws of descent and distribution.  So long as a Participant lives, only such Participant or his or her guardian or legal representative shall have the right to exercise such Award.

Section 5.5.          Beneficiary.  A Participant may file with the Company a written designation of beneficiary, on such form as may be prescribed by the Committee, to receive any Shares, Awards or payments that become deliverable to the Participant pursuant to the Plan after the Participant's death.  A Participant may, from time to time, amend or revoke a designation of beneficiary.  If no designated beneficiary survives the Participant, the executor or administrator of the Participant's estate shall be deemed to be the Participant’s beneficiary.

Section 5.6.         Non-uniform Determinations.  Determinations by the Committee under the Plan (including, without limitation, determinations of the Eligible Persons to receive Awards, the form, amount and timing of Awards, the terms and provisions of Awards and the agreements evidencing Awards and provisions with respect to termination of employment) need not be uniform and may be made by the Committee selectively among persons who receive, or are eligible to receive, Awards under the Plan, whether or not such persons are similarly situated.

Section 5.7.          Duration and Termination.  No awards shall be made under the Plan after April 23, 2022, provided that no Incentive Stock Option shall be granted under the Plan on or after the tenth anniversary of the effective date of the Plan.  The Board may suspend, discontinue or terminate the Plan at any time.  The suspension, discontinuance or termination of the Plan shall not impair any of the rights of any holder of any Award outstanding on the date of the Plan's suspension, discontinuance or termination without the holder's written consent.

Section 5.8.         Withholding.  Prior to the issuance of any Shares under the Plan, arrangements satisfactory to the Committee in its sole discretion shall have been made for the Participant’s payment to the Company of the amount, if any, that the Committee determines to be necessary for the Company or Subsidiary employing the Participant to withhold in accordance with applicable federal or state income tax withholding requirements.  If the Committee allows Shares to be withheld from an Award to satisfy such withholding requirements, the amount withheld in Shares shall not exceed the minimum amount required to be withheld, determined on the date that the amount of tax to be withheld is to be determined.  When payments under the Plan are made in cash, such payments shall be net of an amount sufficient to satisfy such withholding requirements.

Section 5.9.          Agreements and Undertakings.  As a condition of any issuance or transfer of Shares, the Committee may obtain such agreements or undertakings, if any, as it may deem necessary or advisable to assure compliance with any provision of the Plan, any agreement or any law or regulation including, but not limited to, the following:

(a)           a representation, warranty or agreement by the Participant to the Company that the Participant is acquiring the Shares for investment and not with a view to, or for sale in connection with, the distribution of any such Shares; and

(b)           a representation, warranty or agreement to be bound by any restrictions that are, in the opinion of the Committee, necessary or appropriate to comply with the provisions of any securities law deemed by the Committee to be applicable to the issuance of the Shares.

Section 5.10.       Uncertificated Shares.  In lieu of issuing stock certificates for Shares acquired pursuant to the Plan, the Company may issue such Shares in book-entry or other electronic or uncertificated form, unless prohibited by applicable law or regulation or by applicable stock exchange rules.

Section 5.11.       Governing Law.  The Plan shall be governed by the laws of the State of Texas except to the extent that federal law or Nevada corporate law is controlling.

Section 5.12.       Effective Date.  The Plan amends and restates the Existing Plan in its entirety, effective October 31, 2017.
