	  	 Monthly Anniversary Date
 of the Termination Date

		
	Tier 1	  	24 Month
	Tier 2	  	18 Month
	Tier 3	  	18 Month
	Tier 4	  	12 Month

 Except as
provided below with respect to a Specified Employee, the payment of any outplacement benefits provided in this Section 5.01(f) shall be made to a Participant as soon as administratively practicable after the Participant has provided the
appropriate claim documentation, but in no event shall the payment for any such outplacement benefits be paid later than the last day of the calendar year following the calendar year in which the expense was incurred. Notwithstanding anything herein
to the contrary, to the extent required by Section 409A of the Code: (1) the amount of outplacement benefits eligible for reimbursement or to be

  

 -12- 

 
provided as an in-kind benefit under this Plan during a calendar year may not affect the outplacement benefits eligible for reimbursement or to be provided as an in-kind benefit in any other
calendar year, and (2) the right to reimbursement or in-kind benefits under this Plan shall not be subject to liquidation or exchange for another benefit. With respect to a Specified Employee, during the six month period commencing the date
after the Specified Employee’s Termination Date, the cost of any outplacement benefits provided in this Section 5.01(f) which are not otherwise exempt from Section 409A of the Code shall be paid by the Specified Employee to the
outplacement service provider and reimbursed by the Company after the completion of such six month period but no later than the last day of the calendar year following the calendar year in which such outplacement benefits were incurred. 

Section 5.02 Golden Parachute Tax. 
 (a) If any benefit or payment by the Company or its subsidiaries to a Tier 1, Tier 2, or Tier 3 Participant (whether paid or payable or distributed or distributable pursuant to the terms of this Plan or
otherwise, including any acceleration of vesting or payment) (a “Payment”) is determined to be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties are incurred by such Tier 1, Tier 2, or Tier 3
Participant with respect to such excise tax (such excise tax, together with any such interest and penalties, being herein collectively referred to as the “Excise Tax”), then the Tier 1, Tier 2, or Tier 3 Participant shall be entitled to
receive an additional payment (the “Gross-Up Payment”) in an amount such that the net amount of such additional payment retained by Executive, after payment of all federal, state and local income and employment taxes (including, without
limitation, any federal, state, and local income and employment taxes and Excise Tax imposed on the Gross-Up Payment), shall be equal to the Excise Tax imposed on the Payment. The payment of any Gross-Up Payment shall be made prior to the date the
Tier 1, Tier 2, or Tier 3 Participant is to remit the Excise Tax as provided under the Code. 
 (b) Anything in this Plan to the
contrary notwithstanding, in the event it shall be determined that any Payment would be subject to the Excise Tax, then in the case of a Tier 4 Participant, after taking into account any reduction in the Payments provided by reason of section 280G
of the Code in such other plan, arrangement or agreement, the cash severance payments shall first be reduced, and the noncash severance payments shall thereafter be reduced, to the extent necessary so that no portion of the Payments is subject to
the Excise Tax but only if (A) the net amount of such Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Payments and after taking into account the phase out of itemized
deductions and personal exemptions attributable to such reduced Total Payments) is greater than or equal to (B) the net amount of such Payments without such reduction (but after subtracting the net amount of federal, state and local income
taxes on such Total Payments and the amount of Excise Tax to which the Tier 4 Participant would be subject in respect of such unreduced Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable
to such unreduced Payments); provided, however, that the Tier 4 Participant may elect to have the noncash severance payments reduced (or eliminated) prior to any reduction of the cash severance payments. 
 (c) Subject to the provisions of Section 5.02(d) hereto, all determinations required to be made under this Section 5.02, including
whether and when a Gross-Up Payment is

  

 -13- 

 
required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by an independent accounting firm of nationally recognized
standing selected by the Company and which is not serving as accountant or auditor for the Company or the individual, entity or group effecting the Change in Control (the “Accounting Firm”), which shall provide detailed supporting
calculations both to the Company and the Participant within 30 business days of the receipt of the notice from the Participant that there has been a Payment or such earlier time as is requested by the Company. All fees and expenses of the Accounting
Firm shall be borne solely by the Company. Any determination by the Accounting Firm shall be binding upon the Company and the Participant. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial
determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments will not have been made by the Company which should have been made (“Underpayment”), consistent with the calculations required to be made hereunder. In
the event that the Company exhausts its remedies pursuant to Section 5.02(d) hereof and a Tier 1, Tier 2, or Tier 3 Participant thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the
Underpayment that has occurred and the amount of the Underpayment shall be promptly paid by the Company to or for the benefit of the Tier 1, Tier 2, or Tier 3 Participant. 
 (d) A Tier 1, Tier 2, or Tier 3 Participant shall notify the Company in writing of any claim by the Internal Revenue Service that, if
successful, would require the payment by the Company of a Gross-Up Payment. Such notification shall be given as soon as practicable but no later than ten business days after a Tier 1, Tier 2, or Tier 3 Participant is informed in writing of such
claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. A Tier 1, Tier 2, or Tier 3 Participant shall not pay such claim prior to the expiration of the 30-day period following the
date on which it gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies a Tier 1, Tier 2, or Tier 3 Participant in writing prior to the
expiration of such period that it desires to contest such claim, a Tier 1, Tier 2, or Tier 3 Participant shall: 
 (i) give the Company any information reasonably requested by the Company relating to such claim; 
 (ii)
take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including without limitation, accepting legal representation with respect to such claim by an attorney reasonably
selected by the Company; 
 (iii) cooperate with the Company in good faith in order to effectively contest such
claim; and 
 (iv) permit the Company to participate in any proceedings relating to such claim; provided,
however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold a Tier 1, Tier 2, or Tier 3 Participant harmless, on an
after-tax basis, for any Excise Tax or federal, state and local income and employment tax (including interest and penalties with respect thereto) imposed as a result of such

  

 -14- 

 
representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Section 5.02(d), the Company shall control all proceedings taken in connection with
such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct a Tier 1, Tier 2, or
Tier 3 Participant to pay the tax claimed and sue for a refund or to contest the claim in any permissible manner, and the Tier 1, Tier 2, or Tier 3 Participant agrees to prosecute such contest to a determination before any administrative tribunal,
in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs a Tier 1, Tier 2, or Tier 3 Participant to pay such claim and sue for a refund, the Company shall
advance the amount of such payment to the Tier 1, Tier 2, or Tier 3 Participant, on an after-tax basis, and shall hold Tier 1, Tier 2, or Tier 3 Participant harmless from any Excise Tax or federal, state or local income or employment tax (including
interest or penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance; and further provided that any extension of the statute of limitations relating to payment of taxes
for the taxable year of the Tier 1, Tier 2, or Tier 3 Participant with respect to which such contested amount is claimed to be due is limited solely to such contested amount. The Company’s control of the contest, however, shall be limited to
issues with respect to which a Gross-Up Payment would be payable hereunder, and the Tier 1, Tier 2, or Tier 3 Participant shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other
taxing authority. 
 (e) If, after the receipt by a Tier 1, Tier 2, or Tier 3 Participant of an amount advanced by the Company
pursuant to Section 5.02(d), a Tier 1, Tier 2, or Tier 3 Participant becomes entitled to receive any refund with respect to such claim, the Tier 1, Tier 2, or Tier 3 Participant shall (subject to the Company’s complying with the
requirements of Section 5.02(d)) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by a Tier 1, Tier 2, or Tier 3 Participant of an
amount advanced by the Company pursuant to Section 5.02(d), a determination is made that the Tier 1, Tier 2, or Tier 3 Participant shall not be entitled to any refund with respect to such claim and the Company does not notify the Tier 1, Tier
2, or Tier 3 Participant in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance
shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid. 
 (f) In the event that the Excise Tax
is subsequently determined to be less than initially determined by the Accounting Firm, a Tier 1, Tier 2, or Tier 3 Participant shall repay to the Company at the time that the amount of such reduction in Excise Tax is determined (but, if previously
paid to the taxing authorities, not prior to the time the amount of such reduction is refunded to the Tier 1, Tier 2, or Tier 3 Participant or otherwise realized as a benefit by a Tier 1, Tier 2, or Tier 3 Participant) the portion of the Gross-Up
Payment that would not have been paid if the Excise Tax as subsequently determined had been applied in initially calculating the Gross-Up Payment, with the amount of such repayment determined by the Accounting Firm. 
  

 -15- 

 Section 5.03 Condition to Receipt of Severance Benefits. As a condition to
receipt of any payment or benefits under this Article V, such Participant must enter into a Non-Solicitation, Non-Disclosure, Non-Disparagement and Release Agreement with the Company and its affiliates in the form then currently used by the company
which terminates on the monthly anniversary date of each Participant’s Termination Date as set forth below: 
  

			
	 Participant
	  	 Monthly Anniversary Date
 of the Termination Date

		
	Tier 1	  	36 Month
	Tier 2	  	36 Month
	Tier 3	  	36 Month
	Tier 4	  	24 Month

 Section 5.04
Limitation of Benefits. 
 (a) Anything in this Plan to the contrary notwithstanding, the Company’s obligation to
provide the Continued Benefits shall cease if and when the Participant becomes employed by a third party that provides such Participant with substantially comparable health and welfare benefits. 
 (b) Any amounts payable under this Plan shall be in lieu of and not in addition to any other severance or termination payment under any
other plan or agreement with the Company. Without limiting the generality of the foregoing, in the event that a Participant becomes entitled to any payment under this Plan, such Participant shall not be entitled to receive any payment under the
Company’s Executive Severance Plan. As a condition to receipt of any payment under this Plan, the Participant shall waive any entitlement to any other severance or termination payment by the Company. 
 ARTICLE VI 
 DISPUTE RESOLUTION 
 Section 6.01 Negotiation. In case a claim, dispute or controversy shall arise
between any Participant (or any person claiming by, through or under any Participant) and the Company (including the Compensation Committee) relating to or arising out of this Plan, either disputant shall give written notice to the other disputant
(“Dispute Notice”) that it wishes to resolve such claim, dispute or controversy by negotiations, in which event the disputants shall attempt in good faith to negotiate a resolution of such claim, dispute or controversy. If the claim,
dispute or controversy is not so resolved within 30 days after the effective date of the Dispute Notice (as described in section 7.08), either disputant may initiate arbitration of the claim, dispute or controversy as provided in Section 6.02,
except in the case of a dispute regarding the determination of Good Reason which shall be adjudicated by the [Bankruptcy Court]. All negotiations pursuant to this Section 6.01 shall be held at the Company’s principal offices in Houston,
Texas (or such other place as the disputants shall mutually agree) and shall be treated as compromise and settlement negotiations for the purposes of the federal and state rules of evidence and procedure. 
  

 -16- 

 Section 6.02 Arbitration. Any claim, dispute or controversy arising out of or
relating to this Plan which has not been resolved by negotiations in accordance with Section 6.01 within 30 days of the effective date of the Dispute Notice (as described in Section 7.08) shall, upon the written request of either
disputant, be finally settled by arbitration conducted expeditiously in accordance with the commercial arbitration rules of the American Arbitration Association regarding resolution of employment-related disputes. The arbitrator may, without
limitation, award injunctive relief, but shall not be empowered to award damages in excess of compensatory damages and each disputant shall be deemed to have irrevocably waived any damages in excess of compensatory damages, such as punitive damages.
The arbitrator’s decision shall be final and legally binding on the disputants and their successors and assigns, and judgment by the arbitrator may be entered in any court having jurisdiction. Each party shall pay its own fees, disbursements,
and costs relating to or arising out of any arbitration, provided that the Company shall pay on behalf of the Participant all fees, disbursements, and costs relating to or arising out of any arbitration in respect of any claim brought by a
Participant at any time following a Change in Control. All arbitration conferences and hearings shall be held within a thirty (30) mile radius of Houston, Texas. 
 ARTICLE VII 
 MISCELLANEOUS PROVISIONS 
 Section 7.01 Cumulative Benefits. Except as provided in Sections 4.02 and 5.03, the rights and benefits provided to any
Participant under this Plan are in addition to and shall not be a replacement of, all of the other rights and benefits provided to such Participant under any Benefit Plan or any agreement between such Participant and the Company except for any
severance or termination benefits. 
 Section 7.02 No Mitigation. No Participant shall be required to mitigate the
amount of any payment provided for in this Plan by seeking or accepting other employment following a termination of his or her employment with the Company or otherwise. Except as otherwise provided in Sections 4.03 and 5.04, the amount of any
payment provided for in this Plan shall not be reduced by any compensation or benefit earned by a Participant as the result of employment by another employer or by retirement benefits. The Company’s obligations to make payments to any
Participant required under this Plan shall not be affected by any set off, counterclaim, recoupment, defense or other claim, right or action that the Company may have against such Participant. 
 Section 7.03 Amendment or Termination. The Board may amend or terminate the Plan at any time; provided, however, that the Plan
may not be amended or terminated during the pendency of, or within six (6) months following, a Potential Change in Control, or within two (2) years following a Change in Control. Notwithstanding the foregoing, nothing herein shall abridge
the authority of the Compensation Committee to designate a new Participant or to determine that a Participant shall no longer be entitled to participate in the Plan in accordance with section 2.01(a) hereof. The Plan shall terminate when all of the
obligations to Participants hereunder have been satisfied in full. 
 Section 7.04 Enforceability. The failure of
Participants or the Company to insist upon strict adherence to any term of the Plan on any occasion shall not be considered a waiver of such party’s rights or deprive such party of the right thereafter to insist upon strict adherence to that
term or any other term of the Plan. 
  

 -17- 

 Section 7.05 Administration. 
 (a) The Compensation Committee shall have full and final authority, subject to the express provisions of the Plan, with respect to
designation of Participants and administration of the Plan, including but not limited to, the authority to construe and interpret any provisions of the Plan and to take all other actions deemed necessary or advisable for the proper administration of
the Plan. 
 (b) The Company shall indemnify and hold harmless each member of the Compensation Committee and any other employee
of the Company that acts at the direction of the Compensation Committee against any and all expenses and liabilities arising out of his or her administrative functions or fiduciary responsibilities, including any expenses and liabilities that are
caused by or result from an act or omission constituting the negligence of such member in the performance of such functions or responsibilities, but excluding expenses and liabilities that are caused by or result from such member’s or
employee’s own gross negligence or willful cause. Expenses against which such member or employee shall be indemnified hereunder shall include, without limitation, the amounts of any settlement or judgment, costs, counsel fees, and related
charges reasonably incurred in connection with a claim asserted or a proceeding brought or settlement thereof. 
 Section 7.06 Consolidations, Mergers, Etc. In the event of a merger, consolidation or other transaction, nothing herein shall relieve the Company from any of the obligations set forth in the Plan; provided, however, that nothing
in this Section 5.06 shall prevent an acquirer of or Successor to the Company from assuming the obligations, or any portion thereof, of the Company hereunder pursuant to the terms of the Plan provided that such acquirer or Successor provides
adequate assurances of its ability to meet this obligation. In the event that an acquirer of or Successor to the Company agrees to perform the Company’s obligations, or any portion thereof, hereunder, the Company shall require any person, firm
or entity which becomes its Successor to expressly assume and agree to perform such obligations in writing, in the same manner and to the same extent that the Company would be required to perform hereunder if no such succession had taken place.

 Section 7.07 Successors and Assigns. This Plan shall be binding upon and inure to the benefit of the Company and
its Successors and assigns. This Plan and all rights of each Participant shall inure to the benefit of and be enforceable by such Participant and his or her personal or legal representatives, executors, administrators, heirs and permitted assigns.
If any Participant should die while any amounts are due and payable to such Participant hereunder, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Plan to such Participant’s devisees,
legatees or other designees or, if there be no such devisees, legatees or other designees, to such Participant’s estate. No payments, benefits or rights arising under this Plan may be assigned or pledged by any Participant, except under the
laws of descent and distribution. 
  

 -18- 

 Section 7.08 Notices. All notices and other communications provided for in this
Plan shall be in writing and shall be sent, delivered or mailed, addressed as follows: (a) if to the Company, at the Company’s principal office address or such other address as the Company may have designated by written notice to all
Participants for purposes hereof, directed to the attention of the General Counsel, and (b) if to any Participant, at his or her residence address on the records of the Company or to such other address as he or she may have designated to the
Company in writing for purposes hereof. Each such notice or other communication shall be deemed to have been duly given or mailed by United States certified or registered mail, return receipt requested, postage prepaid, except that any change of
notice address shall be effective only upon receipt. 
 Section 7.09 Tax Withholding. The Company shall have the
right to deduct from any payment hereunder all taxes (federal, state or other) which it is required to withhold therefrom. 
 Section 7.10 No Employment Rights Conferred. This Plan shall not be deemed to create a contract of employment between any Participant and the Company and/or its affiliates. Nothing contained in this Plan shall (i) confer
upon any Participant any right with respect to continuation of employment with the Company or (ii) subject to the rights and benefits of any Participant hereunder, interfere in any way with the right of the Company to terminate such
Participant’s employment at any time. 
 Section 7.11 Entire Plan. This Plan contains the entire understanding
of the Participants and the Company with respect to severance arrangements maintained on behalf of the Participants by the Company. There are no restrictions, agreements, promises, warranties, covenants or undertakings between the Participants and
the Company with respect to the subject matter herein other than those expressly set forth herein. 
 Section 7.12 Prior
Agreements. Except as provided in Section 7.15 below, this Plan supersedes all prior agreements, programs and understandings (including verbal agreements and understandings) between the Participants and the Company regarding the terms and
conditions of Participant’s severance arrangements in the event of a Change in Control. 
 Section 7.13
Severability. If any provision of the Plan is, becomes or is deemed to be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions of this Plan shall not be affected thereby.

 Section 7.14 Governing Law. This Plan shall be governed by and construed in accordance with the laws of the State
of Delaware, without giving effect to its conflict of laws rules, and applicable federal law. 
 Section 7.15 Employment
Agreements. Notwithstanding anything herein to the contrary, if any Participant has entered into an employment agreement with the Company, then the severance benefits provided for in such employment agreement shall be the only severance benefits
such Participant shall be entitled to, and the severance benefits under the employment agreement shall supersede the severance benefits provided under this Plan.

grant policies). For option grants, one-third (1/3) of the shares subject to the Initial Grant will vest on the one-year anniversary of vesting start date, with 1/36 of the total shares subject to the Initial Grant vesting monthly over the next
two years, such that the Initial Grant will be fully vested three (3) years following the vesting start date, subject to the Outside Director continuing his or her service on such dates. For restricted stock unit grants, one-third (1/3) of
the shares subject to the Initial Grant will vest on each of the first three anniversaries of the vesting start date, such that the Initial Grant will be fully vested three (3) years following the vesting start date, subject to the Outside
Director continuing his or her service on such dates. 

	 	•	 	 Annual Grant. At each annual meeting after the first year of service on the Board, each Outside Director will receive an additional option or

Company’s equity grant policies) (the “Annual Grant”). The vesting schedules for Annual Grants will be the same as those for Initial Grants. 

 Any equity grants made to the Outside Directors pursuant to this Policy will be subject to the terms and conditions of the 2006 Equity Incentive Plan (the “Plan”), or such other equity
