that the Administrator deems necessary or advisable for administering the Plan.

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted under this Plan shall be exercisable according to the
terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option shall be deemed exercised when the Company receives: (x) written or electronic notice of exercise
(in accordance with the Award Agreement) from the person entitled to exercise the Option, and (y) full payment for the Shares with respect to which the Option is exercised (including provision for any applicable tax withholding). Full payment
may consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Participant or, if requested
by the Participant, in the name of the Participant and his spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or
receive dividends or any other rights as a stockholder shall exist with respect to the Awarded Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is
exercised. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 16 of the Plan or the applicable Award Agreement. Exercising an Option
in any manner shall decrease the number of Shares thereafter available for sale under the Option, by the number of Shares as to which the Option is exercised. 

(ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the
Participant’s death or Disability, the Participant may exercise his Option within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option shall remain exercisable for 30 days following the Participant’s termination after which the
Option shall terminate. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his entire Option, the Shares covered by the unvested portion of the Option shall revert to the
Plan. If the Participant does not exercise his Option as to all of the vested Shares within the time specified by the Award Agreement, the Option shall terminate, and the remaining Shares covered by the Option shall revert to the Plan. 

(iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of his Disability, the Participant
may exercise his Option, to the extent vested, within the time specified in the Award Agreement (but in no event later than the expiration of the term of the Option as set forth in the Award Agreement). If no time for exercise of the Option on
Disability is specified in the Award Agreement, the Option shall remain exercisable for 12 months following the Participant’s termination for Disability. Unless otherwise provided by the Administrator, on the date of termination for
Disability, the unvested portion of the Option shall revert to the Plan. If after termination for Disability, the Participant does not exercise his Option as to all of the vested Shares within the time specified by the Award Agreement, the
Option shall terminate and the remaining Shares covered by such Option shall revert to the Plan. 
 (iv) Death of
Participant. If a Participant dies while a Service Provider, the Option, to the extent vested, may be exercised within the time specified in the Award Agreement (but in no event may the Option be exercised later than the expiration of the
term of the Option as set forth in the Award Agreement), by the beneficiary designated by the Participant prior to his death; provided that such designation must be acceptable to the Administrator. If no beneficiary has been designated by the
Participant, then the Option may be exercised by the personal representative of the Participant’s estate, or by the persons to whom the Option is transferred pursuant to the Participant’s will or in accordance with

  
 10 

 
the laws of descent and distribution. If the Award Agreement does not specify a time within which the Option must be exercised following a Participant’s death, it shall be exercisable
for 12 months following his death. Unless otherwise provided by the Administrator, if at the time of death, the Participant is not vested as to his entire Option, the Shares covered by the unvested portion of the Option shall immediately revert
to the Plan. If the Option is not exercised as to all of the vested Shares within the time specified by the Administrator, the Option shall terminate, and the remaining Shares covered by such Option shall revert to the Plan. 

(v) Termination for Cause. Unless otherwise determined by the Administrator at the time of grant, or if no rights of the
Participant are reduced, thereafter, if a Participant ceases to be a Service Provider as a result of (x) a termination for Cause or (y) a voluntary resignation by the Participant after the occurrence of an event that would be grounds for a
termination for Cause, all Options, whether vested or not vested, that are held by such Participant shall thereupon terminate and expire as of the date of such termination for no consideration. 

8. Restricted Stock. 

(a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to
time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, shall determine.

Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, shall determine. Unless the Administrator determines otherwise, Shares of Restricted Stock shall be held by
the Company as escrow agent until the restrictions on the Shares have lapsed. 
 (c) Removal of Restrictions. Except as
otherwise provided in this Section 8, Shares of Restricted Stock covered by each Award made under the Plan shall be released from escrow as soon as practical after the last day of the Period of Restriction. The Administrator, in its sole
discretion, may accelerate the time at which any restrictions shall lapse or be removed. 
 (d) Voting Rights. During the Period
of Restriction, Service Providers holding Shares of Restricted Stock may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. 

(e) Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock
shall be entitled to receive all dividends and other distributions paid with respect to such Shares unless otherwise provided in the Award Agreement; provided, that any such dividends or other distributions will be subject to the same vesting
requirements and other restrictions as the underlying Shares of Restricted Stock and shall be paid at the time the Shares of Restricted Stock become vested. If any dividends or distributions are paid in Shares, the Shares shall be subject to
the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid. 
 (f)
Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which restrictions have not lapsed shall revert to the Company and again shall become available for grant under the Plan.

time to time as shall be determined by the Administrator, in its sole discretion. The Administrator shall have complete discretion to determine the number of SARs granted to any Service Provider. The Administrator, subject to the
provisions of the Plan, shall have complete discretion to determine the terms and conditions of SARs granted under the Plan, including the sole discretion to accelerate exercisability at any time.

(b) SAR Agreement. Each SAR grant shall be evidenced by an Award Agreement that shall specify the exercise price, the term, the
conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, shall determine. 
 (c)
Expiration of SARs. A SAR granted under the Plan shall expire upon the date determined by the Administrator, in its sole discretion, as set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Sections 7(d)(ii),
7(d)(iii), 7(d)(iv) and 7(d)(v) shall also apply to SARs. 
 (d) Payment of SAR Amount. Upon exercise of a SAR, a Participant
shall be entitled to receive payment from the Company in an amount determined by multiplying: 
 (i) The difference between the Fair Market
Value of a Share on the date of exercise over the exercise price; times 
 (ii) The number of Shares with respect to which the SAR is
exercised. 
 (iii) At the sole discretion of the Administrator, the payment upon the exercise of a SAR may be in cash, in Shares of
equivalent value, or in some combination thereof. 
 10. Performance Units and Performance Shares. 

(a) Grant of Performance Units and Performance Shares. Subject to the terms and conditions of the Plan, Performance Units and
Performance Shares may be granted to Service Providers at any time and from time to time, as shall be determined by the Administrator in its sole discretion. The Administrator shall have complete discretion in determining the number of
Performance Units and Performance Shares granted to each Service Provider. 
 (b) Value of Performance Units and Performance
Shares. Each Performance Unit shall have an initial value established by the Administrator on or before the date of grant. Each Performance Share shall have an initial value equal to the Fair Market Value of a Share on the date of
grant. 
 (c) Performance Objectives and Other Terms. The Administrator shall set Performance Goals or other performance
objectives in its sole discretion which, depending on the extent to which they are met, shall determine the number or value of Performance Units and Performance Shares that shall be paid out to the Participant. Each award of Performance Units
or Performance Shares shall be evidenced by an Award Agreement that shall specify the Performance Period and such other terms and conditions as the Administrator in its sole discretion shall determine. The Administrator may set Performance
Goals or performance objectives based upon the achievement of Company-wide, divisional, 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. 

  
 12 

 (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 earned Performance Shares, if any, 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. 

(g) Termination for Cause. Unless otherwise determined by the Administrator at the time of grant, or if no rights of the
Participant are reduced, thereafter, if a Participant ceases to be a Service Provider as a result of (x) a termination for Cause or (y) a voluntary resignation by the Participant after the occurrence of an event that would be grounds for a
termination for Cause, all Performance Units and Performance Shares, whether vested or not vested, that are held by such Participant shall thereupon terminate and expire as of the date of such termination for no consideration. 

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. 

  
 13 

 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 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. Repurchase Rights. To the extent that the Common Stock is not listed on any established stock exchange or a national market
system, all Awards issued or issuable pursuant to this Plan, including Shares issued in respect thereof, shall be subject to the Company repurchase rights as follows: 

(a) Company Repurchase Rights.

(i) In the event of a Participant’s termination of employment or service for Cause (or a voluntary termination after the occurrence of
an event that would be, as determined by the Administrator, grounds for a termination of employment or service for Cause) or a Participant’s breach of any non-competition, non-solicitation, non-disparagement, confidentiality or similar
restrictive covenant agreement with the Company or its Subsidiaries, the Company may, at any time during the period commencing on the six (6)-month anniversary of such termination for Cause or breach, as applicable, and ending on the two (2)-year
anniversary of such termination for Cause or breach, repurchase from the Participant any Common Stock previously acquired by the Participant pursuant to an Award under the Plan at a repurchase price equal to the lesser of (i) the original purchase
price or exercise price (as applicable), and (ii) Fair Market Value as of the date of repurchase. 
 (ii) Unless otherwise provided in a
Participant’s Award Agreement, in the event of a Participant’s termination for any reason other than as described in Section 15(b)(i) hereof, the Company may at any time during the ninety (90) day period commencing on the six (6) month
anniversary of such termination or the date on which the Participant acquires Common Stock pursuant to an Award hereunder following such termination, as applicable: (i) repurchase from the Participant each outstanding vested Option or Stock
Appreciation Right based on the difference between the exercise price of a share of Common Stock relating to such Option or Stock Appreciation Right and the Fair Market Value of a share of Common Stock on the date of repurchase, and (ii) repurchase
from the Participant any Common Stock previously acquired by the Participant pursuant to an Award under the Plan at a repurchase price equal to Fair Market Value as of the date of repurchase. 

(iii) If the Company elects to exercise the rights under this Section 15(b), the Company shall do so by delivering to the Participant a
notice of such election, specifying the number of shares of Common Stock to be purchased and the closing date and time of such purchase. Such closing shall take place within thirty (30) days following such notice (provided, that such time shall
be extended as necessary to comply with the requirements of the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, or other applicable legal requirements) at the Company’s principal executive offices, or at such other time and
location as the parties to such purchase may mutually determine. At such closing, the Company shall pay the Participant the repurchase price as specified in this Section 15(b) in cash or by cancellation of indebtedness of the
Participant. The Company will be entitled to receive customary representations and warranties from the Participant regarding the Common Stock being repurchased including, but not limited to, the representation that the Participant has good and
marketable title to the Common Stock to be repurchased free and clear of all liens, claims and other encumbrances. 
 (iv) All repurchases
shall be subject to applicable restrictions contained in the Delaware General Corporation Law and in the Company’s and its Subsidiaries’ debt financing agreements. If any such restrictions prohibit the repurchase of Common Stock for
cash, the Company shall have the right to deliver, as payment of the repurchase price, a subordinated note or notes payable in 

  
 14 

 
up to five equal annual installments beginning on the first anniversary of the repurchase closing and bearing an annual interest rate compounded annually equal to the applicable federal rate then
in effect (provided that such notes shall accelerate and be payable in full once the Company is permitted to repurchase the Common Stock or repay such notes under the debt financing agreements or, if earlier, upon a Change in Control). Any such
notes issued by the Company shall be subject to any restrictive covenants in the debt financing agreements to which the Company and its Subsidiaries is subject at the time of the repurchase closing. If any such restrictions prohibit the
repurchase of Common Stock for such subordinated notes, then the time periods provided herein for repurchases shall be suspended, and the Company may make such repurchases as soon as it is permitted to do so under such restrictions. 

(b) Effect of Public Offering. For the avoidance of doubt, the Company shall cease to have rights pursuant to this Section 15
following the completion of a bona fide initial public offering pursuant to an effective registrations statement filed with the U.S. Securities and Exchange Commission under the Securities Act. 

16. 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) of the Plan. 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 16(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, the Participant shall (A) fully vest in and have the right to exercise each outstanding time-vesting Option and SAR as to all of the Awarded Stock, including Shares as to which it would not
otherwise be vested or exercisable and (B) vest in each outstanding performance-vesting Option and SAR subject to the actual achievement of the applicable Performance Goals as of the date of the Change in Control, or as otherwise determined to be
reasonable by the Administrator, in its sole discretion. Any unvested Awards that do not vest in connection with a Change in Control pursuant to this Section 16(c)(i) (after giving effect to the preceding sentence) shall be automatically
cancelled and forfeited for no consideration upon the closing 

  
 15 

 
of such 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. 
 (ii) Restricted
Stock, Performance Shares, Performance Units, Restricted Stock Units and Other Stock-Based Awards. In the event of a Change in Control, the Participant shall (A) fully vest in each outstanding time-vesting Award of Restricted Stock, Restricted
Stock Unit, and Other Stock-Based Award, including as to Shares or Units that would not otherwise be vested, all applicable restrictions shall lapse, and other vesting criteria shall be deemed achieved at
targeted levels and (B) vest in each outstanding performance-vesting Award of Restricted Stock, Restricted Stock Unit, Performance Share, Performance Unit and Other Stock-Based Award, in each case subject
to the actual achievement of the applicable Performance Goals as of the date of the Change in Control, or as otherwise determined to be reasonable by the Administrator, in its sole discretion. Any unvested Awards that do not vest in connection
with a Change in Control pursuant to this Section 16(c)(ii) (after giving effect to the preceding sentence) shall be automatically cancelled and forfeited for no consideration upon the closing of such Change in Control. 

17. 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. 

18. Term of Plan. From its effectiveness, the Plan shall continue in effect for a term of ten years unless terminated earlier
under Section 19 of the Plan. 
 19. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan, subject to the terms and
conditions set forth in the Stockholders Agreement. 
 (b) Stockholder Approval. The Company shall obtain stockholder approval
of (i) any increase of the Award Pool and (ii) any other Plan amendment to the extent necessary to comply with the Stockholders Agreement and 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. 

20. 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. 

  
 16 

 (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 the whole number of Shares covered by the Award sufficient to satisfy the minimum applicable tax
withholding obligations incident to the exercise or vesting of an Award. 
 21. 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. 

22. 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. 
 23. 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. 

24. 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; provided, however, that all shares of Common Stock received by a Participant hereunder (whether issued upon initial
grant of Restricted Shares or Performance Shares or issued upon exercise, vesting or other provision of another Award) and all other Awards, including for the avoidance of doubt after vesting, shall be subject to the terms and conditions of the
Stockholders Agreement, and in connection with any Award Agreement each Participant will become a party to the Stockholders Agreement and agree to be bound thereby (to the extent not already a party thereto). 

25. 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. 

26. 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. 
 27. 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. 

  
 17 

 28. Unfunded Obligation. This Section 28 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. 
 29.
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. 
 30. Construction. Headings in this Plan are included for convenience and shall not be
considered in the interpretation of the Plan. References to sections are to Sections of this Plan unless otherwise indicated. Pronouns shall be construed to include the masculine, feminine, neutral, singular or plural as the identity of
the antecedent may require. This Plan shall be construed according to its fair meaning and shall not be strictly construed against the Company. 

31. Compensation Recoupment. All compensation and Awards payable or paid under the Plan and any sub-plans shall be subject to the
Company’s ability to recover incentive-based compensation from executive officers, as is or may be required by the provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act, any regulations or rules promulgated thereunder, or
any other “clawback” provision required by applicable law or the listing standards of any applicable stock exchange or national market system.

 WARREN RESOURCES, INC. 

2016 EQUITY INCENTIVE PLAN 

RESTRICTED STOCK UNIT AWARD AGREEMENT 

Subject to the terms and conditions of the Notice of Restricted Stock Unit Award (the “Notice”), this Restricted Stock Unit
Award Agreement (this “Award Agreement”), and the Warren Resources, Inc. 2016 Equity Incentive Plan (the “Plan”), the individual set forth in the Notice (the “Participant”)
is hereby granted Restricted Stock Units (the “RSUs”) in Warren Resources, Inc., a Delaware corporation (the “Company”). Unless otherwise specifically indicated, all terms used in this Award
Agreement shall have the meaning as set forth in the Notice or the Plan. 
 1. Vesting Schedule and Risk of Forfeiture.

(a) Vesting Schedule. Subject to the Participant’s continuous service with the Company as a Service Provider and any other
limitations set forth in the Notice, the Plan or this Award Agreement, the RSUs shall vest in accordance with the Vesting Schedule provided in the Notice. 

(b) Risk of Forfeiture. The RSUs shall be subject to a risk of forfeiture until such time the risk of forfeiture lapses in
accordance with the above Vesting Schedule. All or any portion of the RSUs subject to a risk of forfeiture shall automatically be forfeited and immediately returned to the Company if the Participant’s continuous status as a Service
Provider is interrupted or terminated for any reason other than as permitted under the Plan. The Company shall implement any forfeiture under this Section 1 in a unilateral manner, without the Participant’s consent, and with no payment to
the Participant, cash or otherwise, for the forfeited RSUs. 
 2. Dividend Equivalent Rights. Subject to the terms and
conditions of this Award Agreement, the Notice and the Plan, the Participant is hereby granted a Dividend Equivalent Right (the “DER”) to accompany each RSU. Upon payment of a dividend to a holder of Shares, the Company
shall credit the Participant with a dollar amount equal to (i) the per Share dividend payment, multiplied by (ii) the number of unvested RSUs granted pursuant to this Award Agreement, provided that the Participant has not experienced a
“separation from service” (as defined in Treasury Regulation Section 1.409A-1(h)) with the Company and its Affiliates through the date that such dividend payment was made. Any DERs credited pursuant to the foregoing provisions
shall be subject to the same terms and conditions as the RSUs to which they are attributable and shall be forfeited at the same time as the RSUs to which they are attributable. 

3. Settlement of RSUs into Shares. Subject to the terms of this Award Agreement, on the date all or any portion of the RSUs become
nonforfeitable pursuant to the Vesting Schedule, each RSU that becomes nonforfeitable shall immediately and automatically be converted into one Share of the Company’s Common Stock and immediately thereafter shall be granted to the
Participant.

  
 1 

 4. Taxes. The Participant hereby acknowledges and understands that he or she may
suffer adverse tax consequences as a result of the Participant’s receipt of, vesting in, or disposition of, the RSUs. 
 (a)
Representations. The Participant has reviewed with his or her own tax advisors the tax consequences of this Award Agreement and the RSUs granted hereunder, including any U.S. federal, state and local tax laws, and any other applicable
taxing jurisdiction. The Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. The Participant hereby acknowledges and understands that he or she (and not the
Company) shall be responsible for his or her own tax liability that may arise as a result of his or her receiving this Award Agreement and the RSUs granted hereunder. 

(b) Payment of Withholding Taxes. The Participant shall make appropriate arrangements with the Company for the satisfaction of all
U.S. federal, state, local and non-U.S. income and employment tax withholding requirements applicable to any RSUs that settle in Shares in accordance with Section 3. The Committee shall have the sole authority to determine whether a “net
withholding” may be permitted or is required for purposes of the Participant satisfying his or her obligations under this Section 4(b); provided that no Shares shall be withheld with a value exceeding the maximum individual statutory tax rate
for each applicable tax jurisdiction. The Participant hereby acknowledges his or her understanding that the Company’s obligations under this Award Agreement are fully contingent on the Participant first satisfying this Section
4(b). Therefore, a failure of the Participant to reasonably satisfy this Section 4(b) in accordance with the Committee’s sole and absolute discretion shall result in the automatic termination and expiration of this Award Agreement and the
Company’s obligations hereunder. The Participant hereby agrees that a breach of this Section 4(b) shall be deemed to be a material breach of this Award Agreement. 

(c) No Application of Section 409A. The RSUs and this Award Agreement are intended to avoid the application of Section 409A of the
Code (“Section 409A”) because there is no deferral arrangement. Notwithstanding any other provision in the Plan or this Award Agreement to the contrary, the Committee shall have the right, in its sole discretion, to
adopt such amendments to the Plan or this Award Agreement or take such other actions (including amendments and actions with retroactive effect) as the Committee determines are necessary or appropriate for the RSUs to comply with Section 409A. 

(d) Rule 10b5-1 Plan/Arrangement. If the Company does not approve a “net withholding” concept for the Participant to
satisfy his or her withholding obligation, then the Participant may instruct a broker whom it has selected to sell a number of Shares (that are issued under Section 3 hereof) equal to the number of Shares required to satisfy the Company’s
withholding obligations in this Section 4, as determined by the applicable supplemental withholding rate.
