Newpark Resources, Inc. Amended and Restated Employee Stock Purchase Plan

1.Purpose.

The purpose of this Plan is to assist Eligible Employees of the Company, and its Subsidiaries to acquire a stock ownership interest in the Company, thereby attracting, retaining and rewarding such employees and strengthening the mutual interest between employees and the Company’s stockholders. The Plan is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423(b) of the Code, although the Company makes no undertaking or representation to maintain such qualification. Notwithstanding the foregoing, the Company may establish one or more sub-plans of the Plan (and separate Offerings thereunder) which do not qualify as a Code Section 423 employee stock purchase plan for Eligible Employees of Designated Subsidiaries located and established in countries outside of the United States in order to achieve tax, employment, securities law or other purposes and objectives, and to conform the terms of the Plan with the laws and requirements of such countries in order to allow such Eligible Employees to purchase shares of Stock in a manner similar to the Plan.

Appointment of Committee members shall be effective upon acceptance of appointment. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan. Committee members may resign at any time by delivering written notice to the Board. Vacancies in the Committee may only be filled by the Board.

3.2.Action by the Administrator. A majority of the Committee shall constitute a quorum for purposes of any actions taken as the Administrator. The acts of a majority of the Committee members present at any meeting at which a quorum is present, and, subject to applicable law and the Bylaws of the Company, acts approved in writing by a majority of the Committee in lieu of a meeting, shall be deemed the acts of the Administrator. When acting as the Administrator, each member of the Committee is entitled to, in good faith, rely or act upon any report or other information furnished to that member by any officer or other employee of the Company or any Designated Subsidiary, the Company’s independent certified public accountants, or any executive compensation consultant or other professional retained by the Company to assist in the operation, administration and interpretation of the Plan.

3.3.Authority of Administrator. The Administrator shall have the power, subject to, and within the limitations of, the express provisions of the Plan:

(a) To determine when and how rights to purchase stock of the Company shall be granted and the provisions of each offering of such rights (which need not be identical), including establishing the timing and length of Offering Periods and establishing minimum and maximum contribution rates.

(b) To establish new or changing limits on the number of shares of Stock an Eligible Employee may elect to purchase with respect to any Offering Period, if such limits are announced prior to the first Offering Period to be affected.

(c) To establish, in its sole discretion, sub-plans of the Plan (and separate Offerings thereunder) which do not satisfy the requirements of Code Section 423 for purposes of effectuating the participation of Eligible Employees employed by a Designated Subsidiary established in a country outside of the United States. For purposes of the foregoing, the Administrator may establish one or more sub-plans (and separate Offerings thereunder) to: (i) amend or vary the terms of the Plan in order to conform such terms with the laws, rules and regulations of each country outside of the United States where the Designated Subsidiary is located and established; (ii) amend or vary the terms of the Plan in each country where the Designated Subsidiary is located and established as it considers necessary or desirable to take into account or to mitigate or reduce the burden of taxation and social insurance contributions for Participants or the Designated Subsidiary, or (iii) amend or vary the terms of the Plan in each country outside of the United States where the Designated Subsidiary is located and established as it considers necessary or desirable to meet the goals and objectives of the Plan. Each sub-plan established hereunder shall be reflected in a written appendix to the Plan for each Designated Subsidiary in such country, and shall be treated as being separate and

independent from the Plan; provided, the total number of shares of Stock authorized to be issued under the Plan shall include any shares of Stock issued under such non-Code Section 423 sub-plans. To the extent permitted under applicable law, the Administrator may delegate its authority and responsibilities hereunder to an appropriate sub-committee consisting of one or more officers of the Company.

(d) To designate from time to time which Subsidiaries of the Company shall be Designated Subsidiaries, which designation may be made without the approval of the stockholders of the Company. The Administrator may provide that the non-U.S. Eligible Employees of any Designated Subsidiary shall only be eligible to participate in the Non-Section 423 Offering.

(e) To construe and interpret the Plan and rights granted under it, and to establish, amend and revoke rules and regulations for its administration. The Administrator, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective.

(f) To amend the Plan as provided in ARTICLE 13.

(g) Generally, to exercise such powers and to perform such acts as the Administrator deems necessary or expedient to promote the best interests of the Company and its Subsidiaries and to carry out the intent that the Plan be treated as an “employee stock purchase plan” within the meaning of Section 423 of the Code.

The Administrator shall have the authority to delegate routine day-to-day administration of the Plan to such officers and employees of the Company as the Administrator deems appropriate.

3.4.Decisions Binding. The Administrator’s interpretation of the Plan, any Options granted pursuant to the Plan, and all decisions and determinations by the Administrator with respect to the Plan are final, binding, and conclusive on all parties.

4.Shares Subject to the Plan.

4.1.Number of Shares. Subject to ARTICLE 12, the aggregate number of shares of Stock which may be issued pursuant to rights granted under the Plan shall be 2,000,000 shares. If any Option granted under the Plan shall for any reason terminate without having been exercised, the Stock not purchased under such Option shall again become available for the Plan. For avoidance of doubt, the limitation set forth in this paragraph may be used to satisfy purchases of Shares under either a Section 423 Offering or a NonSection 423 Offering

4.2.Individual Share Limit. Notwithstanding anything herein to the contrary, and in addition to the limitation set forth in Section 8.4, below, the maximum shares of Stock that may be acquired by a Participant pursuant to an Option for each Offering Period is two thousand (2,000) shares of Common Stock. The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of Common Stock an Eligible Employee may purchase on the Purchase Date of each Offering Period.

4.3.Stock Distributed. Any Stock distributed pursuant to the Plan may consist, in whole or in part, of authorized and unissued Stock, treasury stock or Stock purchased on the open market.

5.Offering Periods.

The Administrator may from time to time grant Options to purchase Stock of the Company under the Plan to Eligible Employees during one or more Offering Periods selected by the Administrator commencing on an Enrollment Date. For purposes of the Plan, the Administrator may establish separate Offerings under the Plan (the terms of which need not be identical) in which Eligible Employees of one or more Designated Subsidiaries may participate, even if the dates of the applicable Offering Periods of each such Offering are identical and the provisions of the Plan will separately apply to each Offering. In the event an Offering Period is not designated by the Administrator, the right to purchase Stock of the Company under the Plan shall be granted twice each year on February 15 and August 15 of each calendar year and the term of the Offering Period shall be six months; provided however, that the first Offering Period shall commence on July 1, 2017 and end on August 14, 2017.

6.Participation.

6.1.Eligibility. Any Eligible Employee who shall be employed by the Company or a Designated Subsidiary on the day immediately preceding a given Enrollment Date for an Offering Period shall be eligible to participate in the Plan during such Offering Period, subject to the requirements of this ARTICLE 6 and the limitations imposed by Section 423(b) of the Code.

6.2.Enrollment. Except as otherwise designated by the Administrator, an Eligible Employee may become a Participant in the Plan for an Offering Period during the Enrollment Period prior to the beginning of the Offering Period to which it relates. An election to participate in the Plan shall be made by completing the online enrollment process through the Company’s designated Plan broker (or such other enrollment procedures that the Administrator may establish in its sole discretion). A payroll deduction authorization will be effective for the first Offering Period following the completion of the enrollment process and all subsequent Offering Periods thereafter until (i) the Participant has elected to withdraw from the Plan in accordance with Section 10.1, (ii) the authorization is modified by completing a subsequent online enrollment process in accordance with this ARTICLE 6, (iii) the Participant’s employment is terminated or (iv) the Participant is otherwise ineligible to participate in the Plan. An Eligible Employee may not initiate, increase or decrease Contributions as of any date other than during an Enrollment Period.

6.3.Automatic Re-Enrollment. Following the end of each Offering Period, each Participant shall be automatically re-enrolled in the next Offering Period at the applicable rate of payroll deductions in effect on the last Trading Day of the prior Offering Period or otherwise as provided under ARTICLE 7, unless (i) the Participant has elected to withdraw from the Plan in accordance with Section 10.1, (ii) the Participant’s employment has terminated, or (iii) the Participant is ineligible to participate in the next Offering Period.

6.4.Non-U.S. Employees. An Eligible Employee who is a citizen or resident of a jurisdiction other than the United States (without regard to whether such individual also is a citizen or resident of the United States, for tax purposes or otherwise) may be excluded from participation in the Plan or an Offering if the participation of such Eligible Employee is prohibited under the laws of the applicable jurisdiction or if complying with the laws of the applicable jurisdiction would cause the Plan or a Section 423 Offering to violate Section 423 of the Code. In the case of a Non-Section 423 Offering, an Eligible Employee (or group of Eligible Employees) may be excluded from participation in the Plan or an Offering if the Administrator has determined, in its sole discretion, that participation of such Eligible Employee(s) is prohibited under applicable law, or is not advisable or practicable for any reason.

7.Payroll Deductions.

7.1.Payroll Deductions. During the online enrollment process, an Eligible Employee shall authorize a Contribution amount to be withheld by the Company or the Designated Subsidiary employing such Eligible Employee on each payday during an Offering Period as payroll deductions under the Plan. The Contribution shall be designated in a whole percentage between one percent (1%) and ten percent (10%) of the Eligible Employee’s Compensation to be deducted on each payday during an Offering Period and credited to the Participant’s Account for the purchase of Stock pursuant to the Offering. A Participant may elect to have Contributions completely discontinued at any time, but an election to discontinue Contributions during an Offering Period shall be deemed to be an election to withdraw pursuant to Section 10.1. No change in Contributions other than complete discontinuance can be made during an Offering Period, and, specifically, once an Offering Period has commenced, a Participant may not alter the rate of his or her Contribution for such offering. Notwithstanding the foregoing, if local law prohibits payroll deductions, a Participant may elect to participate in an Offering Period through Contributions to his or her Account in a format and pursuant to a process acceptable to the Administrator. In such event, any such Participant shall be deemed to participate in a separate Offering under the Plan, unless the Administrator otherwise expressly provides.

7.2.Frequency of Payroll Deductions. Except as otherwise designated by the Administrator, payroll deductions for a Participant shall commence on the first payroll on or following the Enrollment Date and shall end on the last payroll in the Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in ARTICLE 10.

7.3.Insufficient Payroll Deductions. If in any payroll period a Participant’s Compensation is insufficient (after other authorized deductions) to permit a Contribution, no Contribution shall be made on the effected payroll date. Deduction of the full amount originally elected by the Participant will recommence as soon as his or her Compensation is sufficient to permit such Contribution; provided, however, no additional amounts will be deducted on any future payroll date to satisfy missed Contributions which occurred during insufficient payroll periods.

7.4.Decrease of Payroll Deductions. Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 8.4, a Participant’s Contributions may be suspended by the Administrator at any time during an Offering Period.

8.Grants and Exercise of Rights.

8.1.Grant of Rights. On the Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period shall, subject to the maximum number of shares of Stock specified under Section 4.2 and the provisions of Section 8.4, be granted an Option to purchase that number of shares of Stock equal to the quotient of (i) the aggregate Contributions authorized to be withheld by such Participant in accordance with Section 7.1 for such Offering Period and held in the Participant’s Account, divided by (ii) the Purchase Price of the Stock as of the Enrollment Date.

8.2.Exercise of Rights. Subject to the limitations set forth in Section 8.4, each Participant in the Plan automatically and without any further action will be deemed to have exercised the Participant’s Option on each Purchase Date, to the extent that the balance then in the Participant’s Account under the Plan is sufficient to purchase at the Purchase Price the whole number of shares of Stock subject to the Option granted to such Participant under this Plan for such Offering Period. No fractional shares shall be issued on the exercise of rights granted under this Plan.

8.3.Excess Account Balances. Any amounts remaining in a Participant’s Account as of any Purchase Date after the purchase of Stock shall be distributed to the Participant, without interest, as soon as practicable after the Purchase Date; provided, however, that any amounts attributable to any fractional share that was not purchased on the Purchase Date shall be carried over to the next Offering Period unless the Participant has elected to withdraw from the Plan in accordance with Section 10.1. Notwithstanding the foregoing, the Administrator may, in its sole discretion, establish alternative means for treating amounts remaining in Participant Accounts following any Purchase Date to the extent consistent with applicable law.

8.4.Limitation on Purchase of Stock. In addition to the limitations set forth in Section 4.2, above, an Eligible Employee may not be granted an Option under the Plan if such Option, (together with any other rights granted to such Eligible Employee under “employee stock purchase plans” of the Company, any Parent or any Subsidiary, as specified by Section 423(b)(8) of the Code), excluding Options granted pursuant to any Non-Section 423 Offering, permits such Eligible Employee to purchase Stock of the Company or any Parent or Subsidiary at a rate which exceeds $25,000 of fair market value of such Stock (determined as of the first day of the Offering Period during which such Option is granted) for each calendar year in which such Option is outstanding at any time. This limitation shall be applied in accordance with Section 423(b)(8) of the Code.

8.5.Five Percent Limit. An Eligible Employee may not be granted an Option to purchase Stock under this Plan if such Participant (directly or through attribution), immediately after such Option is granted, would own or hold options to purchase Common Stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or any of its Subsidiaries.

8.6.Pro Rata Allocation of Shares. If the Administrator determines that, on a given Purchase Date, the number of shares of Stock with respect to Options are to be exercised may exceed (i) the number of shares of Stock that were available for issuance under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of shares of Stock available for issuance under the Plan on such Purchase Date, the Administrator may in its sole discretion provide that the Company shall make a pro rata allocation of the shares of Stock available for purchase on such Enrollment Date or Purchase Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participants for whom Options to purchase Stock are to be exercised pursuant to this ARTICLE 8 on such Purchase Date, and shall either (x) continue all Offering Periods then in effect, or (y) terminate any or all Offering Periods then in effect pursuant to ARTICLE 12. The Company may make pro rata allocation of the shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s stockholders subsequent to such Enrollment Date. The balance of the amount credited to the account of each Participant which has not been applied to the purchase of shares of Stock shall be paid to such Participant in one lump sum in cash, without interest, as soon as reasonably practicable after the Purchase Date.

8.7.Withholding. At the time a Participant’s Option under the Plan is exercised, in whole or in part, or at the time some or all of the Stock issued under the Plan is disposed of, the Participant shall make adequate provision for the Company’s federal, state, local, non-U.S. or other tax withholding obligations, if any, which arise upon the exercise of the Option or the disposition of the Stock in accordance with such procedures and withholding methods that may be established by the Administrator in its sole discretion. At any time, the Company or a Designated Subsidiary may, but shall not be obligated to, withhold from the Participant’s compensation or other amounts payable to the Participant the amount necessary to meet applicable withholding obligations, including any withholding required to make available to the Company or a Designated Subsidiary any tax deductions or benefits attributable to sale or early disposition of Stock by the Participant.

9.Issuance of Stock.

9.1.Brokerage Account or Plan Share Account. By enrolling in the Plan, each Participant shall be deemed to have authorized the establishment of a brokerage account on his or her behalf at a securities brokerage firm selected by the Administrator. Alternatively, the Administrator may provide for Plan share accounts for each Participant to be established by the Company or by an outside entity selected by the Administrator which is not a brokerage firm. Stock purchased by a Participant pursuant to the Plan shall be held in the Participant’s brokerage or Plan share account. Participants may be required to enter into agreements and authorizations (the terms of which may include, without limitation, conditions or restrictions on the transfer of shares of Stock from Participants’ brokerage accounts) with the Plan broker selected by the Administrator and the Company as the Company may prescribe.

9.2.Conditions upon Issuance of Stock. The Company shall not be required to issue or deliver any certificate or certificates for shares of Stock purchased upon the exercise of rights under the Plan prior to fulfillment of all of the following conditions:

(a) The admission of such shares to listing on all stock exchanges, if any, on which the Stock is then listed;

(b) The completion of any registration or other qualification of such shares under any state or federal law or under the rulings or regulations of the Securities and Exchange Commission or any other governmental regulatory body, which the Administrator shall, in its absolute discretion, deem necessary or advisable;

(c) The obtaining of any approval or other clearance from any state or federal governmental agency which the Administrator shall, in its absolute discretion, determine to be necessary or advisable;

(d) The payment to the Company of all amounts which it is required to withhold under federal, state or local law upon exercise of the rights, if any; and

(e) The lapse of such reasonable period of time following the exercise of the rights as the Administrator may from time to time establish for reasons of administrative convenience.

10.Withdrawal.

10.1.Withdrawal. A Participant may withdraw all, but not less than all, of the Contributions credited such Participant’s Account and not yet used to exercise such Participant’s Option under the Plan at any time by completing the appropriate online withdrawal process through the Company’s designated Plan broker or contacting the Company. A notice of withdrawal must be received no later than the last day of the month immediately preceding the month of the Purchase Date. Upon receipt of such notice, Contributions on behalf of the Participant shall be discontinued and such Participant may not again be eligible to participate in the Plan until the next Enrollment Period. All of the Participant’s Contributions credited to such Participant’s Account during the Offering Period shall be paid to such Participant, without interest, as soon as reasonably practicable.

10.2.Future Participation. A Participant’s withdrawal from an Offering Period shall not have any effect upon eligibility to participate in any similar plan which may hereafter be adopted by the Company or a Designated Subsidiary or in subsequent Offering Periods which commence after the termination of the Offering Period from which the Participant withdraws.

11.Termination of Employment Eligibility.

11.1.General. If the employment of a Participant terminates prior to the Purchase Date relating to a particular Offering Period for any reason, including retirement, death or failure of a Participant to remain an Eligible Employee of the Company or of a Designated Subsidiary, participation in the Plan immediately and without any act on the part of the Participant shall terminate. Following the Participant’s termination of employment as described above, the Company will refund to the Participant or, in the case of the death of the Participant, the person or persons entitled thereto, any unused Contributions credited to the Participant’s Account during the Offering Period, without interest, and thereupon the Participant’s Option shall terminate.

11.2.Transfer of Employment. A Participant whose employment transfers or whose employment terminates with an immediate rehire (with no break in service) by or between the Company or any Designated Subsidiary (including transfers between Designated Subsidiaries) participating in a Section 423 Offering will not be treated as having terminated employment for purposes of participating in the Plan or an Offering; provided, however, if a Participant transfers from a Section 423 Offering to a Non-Section 423 Offering (or vice versa) or between Non-Section 423 Offerings, the Participant will be treated as having withdrawn from the Offering Period in accordance with ARTICLE 10, unless otherwise determined by the Administrator in its sole decision.

11.3.Leave of Absence.

(a) During a paid leave of absence approved by the Company and meeting the requirements of U.S. Treasury Regulation Section 1.421-1(h)(2), a Participant’s elected Contributions shall continue.

(b) If a Participant takes an unpaid leave of absence that is approved by the Company and meets the requirements of Treasury Regulation Section 1.421-1(h)(2), then Contributions on behalf of the Participant shall be discontinued and no other Contributions shall be permitted (unless otherwise determined by the Administrator or required by applicable law). Any amounts credited to the Participant’s Account may be used to purchase Stock on the next applicable Purchase Date.

(c) If a Participant takes a leave of absence that is not described in Section 11.3(a) or 11.3(b), then the Participant shall be considered to have withdrawn from the Plan in accordance with ARTICLE 10 hereof.

Further, notwithstanding the preceding provisions of this Section 11.3, if a Participant takes a leave of absence and such leave of absence exceeds 90 days, then the Participant shall be considered to have withdrawn from the Plan in accordance with ARTICLE 10 hereof on the 91st day of such leave of absence; provided, however, that if the Participant’s right to employment is guaranteed either by statute or contract, then such 90-day period shall be extended until the last day upon which such reemployment rights are so guaranteed.

12.Adjustments Upon Changes in Stock.

12.1.Changes in Capitalization; Other Adjustments.

(a) Subject to Section 12.3, whenever any change is made in the Stock by reason of any stock dividend or by reason of subdivision, stock split, reverse stock split, combination or exchange of shares, recapitalization, reorganization, reclassification of shares, or any other similar corporate event affecting the Stock, appropriate action will be taken by the Board to make such proportionate adjustments, if any, as the Board in its discretion may deem appropriate to reflect such change with respect to (i) the aggregate number and type of shares of Stock (or other securities or property) that may be issued under the Plan (including, but not limited to, adjustments of the limitations established pursuant to Section 4.2 on the maximum number of shares of Stock that may be purchased); (ii) the class(es) and number of shares and price per share of Stock subject to outstanding Options; and (iii) the Purchase Price with respect to any outstanding Options.

(b) If the Company shall not be the surviving corporation in any merger or consolidation (or survives only as a subsidiary of another entity), or if the Company is to be dissolved or liquidated, then unless a surviving corporation assumes or substitutes new options (within the meaning of Section 424(a) of the Code) for all Options then outstanding under this Plan, (i) the Purchase Date for all Options then outstanding under this Plan shall be accelerated to dates fixed by the Administrator or the Board prior to the effective date of such merger or consolidation or such dissolution or liquidation and (ii) upon such effective date any unexercised Options shall expire.

12.2.No Adjustment under Certain Circumstances. No adjustment or action described in this ARTICLE 12 or in any other provision of the Plan shall be authorized to the extent that such adjustment or action would cause the Plan to fail to satisfy the requirements of Section 423 of the Code.

12.3.No Other Rights. Except as expressly provided in the Plan, no Participant shall have any rights by reason of any subdivision or consolidation of shares of stock of any class, the payment of any dividend, any increase or decrease in the number of shares of stock of any class or any dissolution, liquidation, merger, or consolidation of the Company or any other corporation. Except as expressly provided in the Plan or pursuant to action of the Administrator or the Board under the Plan, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Stock subject to an outstanding Option or the Purchase Price of the Stock subject to an outstanding Option.

13.Amendment, Modification, and Termination.

13.1.Amendment, Modification and Termination. The Administrator or the Board may amend, suspend or terminate the Plan at any time and from time to time; provided, however, that if stockholder approval is required pursuant to the Code, United States federal securities laws or regulations, or the rules or regulations of the New York Stock Exchange (or any other securities exchange on which the Common Stock is listed or traded), then no such amendment shall be effective unless approved by the Company’s stockholders within such time period and manner as may be required. Upon termination of the Plan, all Contributions shall cease and all amounts then credited to a Participant’s Account shall be refunded, without interest, to each Participant.

13.2.Rights Previously Granted. Except as provided in ARTICLE 12 or this ARTICLE 13, no termination, amendment or modification may make any change in any right theretofore granted which adversely affects the rights of any Participant without the consent of such Participant, provided that an Offering Period may be terminated, amended or modified by the Administrator if the Administrator determines that the termination of the Offering Period or the Plan is in the best interests of the Company and its stockholders.

13.3.Certain Changes to Plan. Without stockholder consent and without regard to whether any Participant rights may be considered to have been adversely affected, to the extent permitted by Section 423 of the Code, the Administrator shall be entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed Contribution authorizations, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Stock for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable which are consistent with the Plan.

14.Code Section 409A; Tax Qualification.

14.1.Code Section 409A. Options to purchase Stock granted under a Section 423 Offering are exempt from the application of Section 409A of the Code. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Administrator determines that an Option granted under the Plan may be subject to Section 409A of the Code or that any provision in the Plan would cause an Option under the Plan to be subject to Section 409A of the Code, the Administrator may amend the terms of the Plan and/or of an outstanding Option granted under the Plan, or take such other action the Administrator determines is necessary or appropriate, in each case, without the Participant’s consent, to exempt any outstanding Option or future Option that may be granted under the Plan from or to allow any such Options to comply with Section 409A of the Code, but only to the extent any such amendments or action by the Administrator would not violate Section 409A of the Code. Notwithstanding the foregoing, the Company will have no liability to a Participant or any other party if the Option to purchase Stock under the Plan that is intended to be exempt from or compliant with Section 409A of the Code is not so exempt or compliant or for any action taken by the Administrator with respect thereto. The Company makes no representation that the right to purchase Stock under the Plan is compliant with Section 409A of the Code.

14.2.Tax Qualification. Although the Company may endeavor to (i) qualify an Option to purchase Stock for favorable tax treatment under the laws of the United States or jurisdictions outside of the United States or (ii) avoid adverse tax treatment (e.g., under Section 409A of the Code), the Company makes no representation to that effect and expressly disavows any covenant to maintain favorable or avoid unfavorable tax treatment, notwithstanding anything to the contrary in this Plan, including Section 14.1 above. The Company shall be unconstrained in its corporate activities without regard to the potential negative tax impact on Participant’s under the Plan.

15.Miscellaneous.

15.1.Restriction upon Assignment. An Option granted under the Plan shall not be transferable and is exercisable during the Participant’s lifetime only by the Participant. Any such attempt at assignment, transfer, pledge, or other disposition shall be without effect, and the Company will treat such act as an election to withdraw Participant’s entire Account in accordance with ARTICLE 10.

15.2.Rights as a Stockholder. With respect to shares of Stock subject to an Option granted under the Plan, a Participant shall not be deemed to be a stockholder of the Company, and the Participant shall not have any of the rights or privileges of a stockholder, until such shares have been recorded in the books of the brokerage firm selected by the Administrator or, as applicable, the Company, its transfer agent, stock plan administrator or such other outside entity which is not a brokerage firm. No adjustments shall be made for dividends (ordinary or extraordinary, whether in cash securities, or other property) or distribution or other rights for which the record date occurs prior to the date of such issuance, except as otherwise expressly provided herein. Unless otherwise determined by the Administrator or required by applicable law, the Company shall not deliver to any Participant any certificates evidencing Stock issued in connection with any purchase under the Plan.

15.3.Participant Accounts. No interest shall accrue on any amounts credited to a Participant Account. All payroll deductions or lump sum contributions of a Participant under the Plan will be deposited with the general funds of the Company and may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deduction amounts.

15.4.Currency Conversion. Eligible Employees who are paid in currency other than U.S. dollars, and who contribute such currency to the Plan through contributions or payroll deductions will have such amounts converted to U.S. dollars. The exchange rate and method for such conversion will be determined as prescribed by the Administrator for each Offering and as may be specified pursuant to any sub-plan established under the Plan. In no event will any procedure implemented for dealing with exchange rate fluctuations that may occur during an Offering result in the acquisition of shares of Stock below the Purchase Price. Each Eligible Employee shall bear the risk of any currency exchange fluctuations (if applicable) between the date on which any Eligible Employee amounts are converted to U.S. dollars and the Purchase Date.

15.5.Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

15.6.Reports. Statements of account shall be given to participating Employees at least annually, which statements shall set forth the amounts of payroll deductions, the Purchase Price, the number of shares purchased and the remaining cash balance, if any.

15.7.No Employment Rights. Nothing in the Plan shall be construed to give any person (including any Eligible Employee or Participant) the right to remain in the employ of the Company or any Parent or Subsidiary or to affect the right of the Company or any Parent or Subsidiary to terminate the employment of any person (including any Eligible Employee or Participant) at any time, with or without cause.

15.8.Severability. If any provision of the Plan shall be held illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining provisions hereof; instead, the provisions shall be fully severable and the Plan shall be construed and enforced as if said illegal or invalid provision had never been included herein.

15.9.Governing Law. The validity and enforceability of this Plan shall be governed by and construed in accordance with the laws of the State of Texas without regard to otherwise governing principles of conflicts of law.
