or individual goals (including solely continued service), applicable federal or state securities laws, or any other basis determined by the Administrator in its sole discretion.

(d) Earning of Performance Units and Performance Shares.  After the applicable Performance Period has ended, the holder of Performance Units or Performance Shares shall be entitled to receive a payout of the number of Performance Units or Performance Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding Performance Goals or performance objectives have been achieved.  After the grant of Performance Units or Performance Shares, the Administrator, in its sole discretion, may reduce or waive any performance objectives for the Performance Unit or Performance Share.

(e) Form and Timing of Payment of Performance Units and Performance Shares.  Payment of earned Performance Units and Performance Shares shall be made after the expiration of the applicable Performance Period at the time determined by the Administrator.  The Administrator, in its sole discretion, may pay earned Performance Units and Performance Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned Performance Units or Performance Shares, as applicable, at the close of the applicable Performance Period) or in a combination of cash and Shares.

(f) Cancellation of Performance Units or Performance Shares.  On the date set forth in the Award Agreement, all unearned or unvested Performance Units and Performance Shares shall be forfeited to the Company, and again shall be available for grant under the Plan.

11. Restricted Stock Units.  Restricted Stock Units shall consist of a Restricted Stock, Performance Share or Performance Unit Award that the Administrator, in its sole discretion permits to be paid out in a lump sum, installments or on a deferred basis, in accordance with rules and procedures established by the Administrator

12. Other Stock Based Awards.  Other Stock Based Awards may be granted either alone, in addition to, or in tandem with, other Awards granted under the Plan and/or cash awards made outside of the Plan.  The Administrator shall have authority to determine the Service Providers to whom and the time or times at which Other Stock Based Awards shall be made, the amount of such Other Stock Based Awards, and all other conditions of the Other Stock Based Awards, including any dividend or voting rights and whether the Award should be paid in cash.

13. Leaves of Absence.  Unless the Administrator provides otherwise, vesting of Awards granted under this Plan shall be suspended during any unpaid leave of absence and shall resume on the date the Participant returns to work on a regular schedule as determined by the Company; provided, however, that no vesting credit shall be awarded for the time vesting has been suspended during such leave of absence.  A Service Provider shall not cease to be an Employee in the case of (i) any leave of absence approved by the Company or (ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary.  For purposes of Incentive Stock Options, no leave of absence may exceed 90 days, unless reemployment upon expiration of such leave is guaranteed by statute or contract.  If reemployment upon expiration of a leave of absence approved by the Company is not guaranteed by statute or contract, then at the end of three months following the expiration of the leave of absence, any Incentive Stock Option held by the Participant shall cease to be treated as an Incentive Stock Option and shall be treated for tax purposes as a Nonstatutory Stock Option.

14. Non-Transferability of Awards.  Unless determined otherwise by the Administrator, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by shall or by the laws of descent or distribution and may be exercised, during the lifetime of the

Participant, only by the Participant.  If the Administrator makes an Award transferable, such Award shall contain such additional terms and conditions as the Administrator deems appropriate.

15. Adjustments; Dissolution or Liquidation; Change in Control.

(a) Adjustments.  In the event of any change in the outstanding Shares of Common Stock by reason of any stock split, stock dividend or other non‑recurring dividends or distributions, recapitalization, merger, consolidation, spin‑off, combination, repurchase or exchange of stock, reorganization, liquidation, dissolution or other similar corporate transaction that affects the Common Stock, an adjustment shall be made, as the Administrator deems necessary or appropriate, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.  Such adjustment may include an adjustment to the number and class of Shares which may be delivered under the Plan, the number, class and price of Shares subject to outstanding Awards, the number and class of Shares issuable pursuant to Options, and the numerical limits in Sections 3 and 6(b).  Notwithstanding the preceding, the number of Shares subject to any Award always shall be a whole number.

(b) Dissolution or Liquidation.  In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each Participant as soon as practical prior to the effective date of the proposed transaction.  The Administrator, in its sole discretion, may provide for a Participant to have the right to exercise his Award, to the extent applicable, until 10 days prior to the transaction as to all of the Awarded Stock covered thereby, including Shares as to which the Award would not otherwise be exercisable.  In addition, the Administrator may provide that any Company repurchase option or forfeiture rights applicable to any Award shall lapse 100%, and that any Award vesting shall accelerate 100%, provided the proposed dissolution or liquidation takes place at the time and in the manner contemplated.  To the extent it has not been previously exercised or vested, an Award shall terminate immediately prior to the consummation of such proposed action.

(c) Change in Control.  This Section 15(c) shall apply except to the extent otherwise provided in the Award Agreement.

(i) Stock Options and SARs.  In the event of a Change in Control, each outstanding Option and SAR shall be assumed or an equivalent option or SAR substituted by the successor corporation or a Parent or Subsidiary of the successor corporation.  Unless determined otherwise by the Administrator, if the successor corporation refuses to assume or substitute for the Option or SAR, the Participant shall fully vest in and have the right to exercise the Option or SAR as to all of the Awarded Stock, including Shares as to which it would not otherwise be vested or exercisable.  If an Option or SAR is not assumed or substituted on the Change in Control, the Administrator shall notify the Participant in writing or electronically that the Option or SAR shall be exercisable, to the extent vested, for a period of up to 15 days from the date of such notice, and the Option or SAR shall terminate upon the expiration of such period.  For the purposes of this Section 15(c)(i), the Option or SAR shall be considered assumed if, following the Change in Control, the option or SAR confers the right to purchase or receive, for each Share of Awarded Stock subject to the Option or SAR immediately prior to the Change in Control, the consideration (whether securities, cash, or property) received in the Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares).  However, if the consideration received in the Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option or SAR, for each share of Awarded Stock subject to the Option or SAR, to be solely common stock of the successor corporation or its Parent equal in Fair Market Value to the per share consideration received by holders of Common Stock in the Change in Control.  Notwithstanding anything in this Plan to the contrary, an Award

(ii) Restricted Stock, Performance Shares, Performance Units, Restricted Stock Units and Other Stock Based Awards.  In the event of a Change in Control, each outstanding Award of Restricted Stock, Restricted Stock Unit, Performance Share, Performance Unit, and Other Stock Based Award shall be assumed or an equivalent Restricted Stock, Restricted Stock Unit, Performance Share, Performance Unit, and Other Stock Based Award shall be substituted by the successor corporation or a Parent or Subsidiary of the successor corporation.  Unless determined otherwise by the Administrator, if the successor corporation refuses to assume or substitute for the Award, the Participant shall fully vest in the Award, including as to Shares or Units that would not otherwise be vested, all applicable restrictions shall lapse, and all performance objectives and other vesting criteria shall be deemed achieved at targeted levels.  For the purposes of this Section 15(c)(ii), an Award of Restricted Stock, Restricted Stock Units, Performance Shares, Performance Units, and Other Stock Based Awards shall be considered assumed if, following the Change in Control, the award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control (and if a Restricted Stock Unit or Performance Unit, for each Share as determined based on the then current value of the unit), the consideration (whether stock, cash, or other securities or property) received in the Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares).  However, if the consideration received in the Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide that the consideration to be received for each Share (and if a Restricted Stock Unit or Performance Unit, for each Share as determined based on the then current value of the unit) be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the Change in Control.  Notwithstanding anything in this Plan to the contrary, an Award that vests, is earned, or is paid‑out upon the satisfaction of one or more performance objectives shall not be considered assumed if the Company or its successor modifies any of the performance objectives without the Participant's consent; provided, however, a modification to the performance objectives only to reflect the successor corporation's post‑Change in Control corporate structure shall not be deemed to invalidate an otherwise valid Award assumption.

(iii) Outside Director Awards.  Notwithstanding any provision of Sections 15(c)(i) or 15(c)(ii) to the contrary, with respect to Awards granted to an Outside Director that are assumed or substituted for, if on the date of or following the assumption or substitution, the Participant's status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation by the Participant, then the Participant shall fully vest in and have the right to exercise his Options and Stock Appreciation Rights as to all of the Award, including Shares as to which such Awards would not otherwise be vested or exercisable, and all restrictions on Restricted Stock and Restricted Stock Units, as applicable, shall lapse, and, with respect to Performance Shares, Performance Units, and Other Stock Based Awards, all performance goals and other vesting criteria shall be deemed achieved at target levels and all other terms and conditions met.

16. Date of Grant.  The date of grant of an Award shall be, for all purposes, the date on which the Administrator makes the determination granting such Award, or a later date as is determined by the Administrator.  Notice of the determination shall be provided to each Participant within a reasonable time after the date of such grant.

17. Stockholder Approval and Term of Plan.  The Plan became effective on September 26, 2013 and thereafter shall continue in effect for a term of ten years unless terminated earlier under Section 18 of the Plan.

18. Amendment and Termination of the Plan.

(a) Amendment and Termination.  The Board may at any time amend, alter, suspend or terminate the Plan.

(b) Stockholder Approval.  The Company shall obtain stockholder approval of any Plan amendment to the extent necessary to comply with Applicable Laws.

(c) Effect of Amendment or Termination.  No amendment, alteration, suspension, or termination of the Plan shall materially or adversely impair the rights of any Participant, unless otherwise mutually agreed upon by the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company.  Termination of the Plan shall not affect the Administrator's ability to exercise the powers granted to it under this Plan with respect to Awards granted under the Plan prior to the date of termination.

19. Conditions upon issuance of shares.

(a) Legal Compliance.  Shares shall not be issued pursuant to the exercise of an Award unless the exercise of the Award and the issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance.

(b) Investment Representations.  As a condition to the exercise or receipt of an Award, the Company may require the person exercising or receiving the Award to represent and warrant at the time of any such exercise or receipt that the Shares are being purchased only for investment and without any present intention to sell or distribute the Shares if, in the opinion of counsel for the Company, such a representation is required.

(c) Taxes.  No Shares shall be delivered under the Plan to any Participant or other person until the Participant or other person has made arrangements acceptable to the Administrator for the satisfaction of any non‑U.S., U.S.‑federal, U.S.‑state, or local income and employment tax withholding obligations, including, without limitation, obligations incident to the receipt of Shares.  Upon exercise or vesting of an Award, the Company shall withhold or collect from the Participant an amount sufficient to satisfy such tax obligations, including, but not limited to, by surrender of up to the whole number of Shares covered by the Award sufficient to satisfy the withholding obligations incident to the exercise or vesting of an Award based on the maximum individual income tax rate in the applicable jurisdiction.

20. Severability.  Notwithstanding any contrary provision of the Plan or an Award to the contrary, if any one or more of the provisions (or any part thereof) of this Plan or the Awards shall be held invalid, illegal, or unenforceable in any respect, such provision shall be modified so as to make it valid, legal, and enforceable, and the validity, legality, and enforceability of the remaining provisions (or any part thereof) of the Plan or Award, as applicable, shall not in any way be affected or impaired thereby.

21. Inability to Obtain Authority.  The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

22. No Rights to Awards.  No eligible Service Provider or other person shall have any claim to be granted any Award pursuant to the Plan, and neither the Company nor the Administrator shall be obligated to treat Participants or any other person uniformly.

23. No Stockholder Rights.  Except as otherwise provided in an Award Agreement, a Participant shall have none of the rights of a stockholder with respect to Shares covered by an Award until the Participant becomes the record owner of the Shares.

24. Fractional Shares.  No fractional Shares shall be issued and the Administrator shall determine, in its sole discretion, whether cash shall be given in lieu of fractional Shares or whether such fractional Shares shall be eliminated by rounding up or down as appropriate.

25. Governing Law.  The Plan, all Award Agreements, and all related matters, shall be governed by the laws of the State of Texas, without regard to choice of law principles that direct the application of the laws of another state.

26. No Effect on Terms of Employment or Consulting Relationship.  The Plan shall not confer upon any Participant any right as a Service Provider, nor shall it interfere in any way with his right or the right of the Company or a Parent or Subsidiary to terminate the Participant's service at any time, with or without cause, and with or without notice.

27. Unfunded Obligation.  This Section 27 shall only apply to Awards that are not settled in Shares.  Participants shall have the status of general unsecured creditors of the Company.  Any amounts payable to Participants pursuant to the Plan shall be unfunded and unsecured obligations for all purposes, including, without limitation, Title I of the Employee Retirement Income Security Act of 1974, as amended.  Neither the Company nor any Parent or Subsidiary shall be required to segregate any monies from its general funds, or to create any trusts, or establish any special accounts with respect to such obligations.  The Company shall retain at all times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its payment obligations under this Plan.  Any investments or the creation or maintenance of any trust for any Participant account shall not create or constitute a trust or fiduciary relationship between the Administrator, the Company or any Parent or Subsidiary and Participant, or otherwise create any vested or beneficial interest in any Participant or the Participant's creditors in any assets of the Company or Parent or Subsidiary.  The Participants shall have no claim against the Company or any Parent or Subsidiary for any changes in the value of any assets that may be invested or reinvested by the Company with respect to the Plan.

28. Section 409A.  It is the intention of the Company that no Award shall be "deferred compensation" subject to Section 409A of the Code, unless and to the extent that the Administrator specifically determines otherwise, and the Plan and the terms and conditions of all Awards shall be interpreted accordingly.  The following rules shall apply to Awards intended to be subject to Section 409A of the Code ("409A Awards"):

(a) Any distribution of a 409A Award following a separation from service that would be subject to Section 409A(a)(2)(A)(i) of the Code as a distribution following a separation from service of a "specified employee" (as defined under Section 409A(a)(2)(B)(i) of the Code) shall occur no earlier than the expiration of the six‑month period following such separation from service.

(b) In the case of a 409A Award providing for distribution or settlement upon vesting or lapse of a risk of forfeiture, if the time of such distribution or settlement is not otherwise specified in the Plan or Award Agreement or other governing document, the distribution or settlement shall be made no

later than March 15 of the calendar year following the calendar year in which such 409A Award vested or the risk of forfeiture lapsed.

(c) In the case of any distribution of any other 409A Award, if the timing of such distribution is not otherwise specified in the Plan or Award Agreement or other governing document, the distribution shall be made not later than the end of the calendar year during which the settlement of the 409A Award is specified to occur.
