 The Board of Directors of KBR, Inc. (the “Board”) previously established the KBR, Inc. 2006 Stock and Incentive Plan (the “2006
Plan”). Section XI of the 2006 Plan authorizes the Compensation Committee of the Board to grant “Performance Awards” with such terms as the Compensation Committee may establish in its discretion. Effective January 1, 2007, the

amended.

Participant’s behalf to a qualified plan maintained by the Company or to any cafeteria plan under Section 125 of the Code maintained by the Company and (ii) deferrals of compensation made at the Participant’s election pursuant to

herein are included solely for convenience, and if there is any conflict between headings and the text of the Plan, the text shall control. 
 ARTICLE III 
 PARTICIPATION 
 3.1 Participants. Active employees who are Senior Executives as of the beginning of each Plan Year shall be Participants for such Plan Year. 
 3.2 Partial Plan Year Participation. If, after the beginning of a Plan Year, an employee who was not previously a Participant for such Plan
Year (i) is newly appointed or elected as a Senior Executive or (ii) returns to active employment as a Senior Executive following a leave of absence, such employee shall become a Participant effective with the first day of the month
following such appointment or election or return to active service, as the case 

  

 4 









 
may be, for the balance of the Plan Year, on a prorated basis, unless the Committee shall determine, in its sole discretion, that the participation shall be
delayed until the beginning of the next Plan Year. 
 If an employee who has previously been designated as a Participant for a particular
Plan Year takes a leave of absence during such Plan Year, the Committee may exercise its discretion to reduce Participant’s rights to a Reward for such Plan Year on a prorated basis corresponding to that portion of the Plan Year during which he
or she was no longer an active Participant, in which case the prorated portion of the Reward shall be paid in accordance with the provisions of Section 6.1. 
 Each Participant shall be assigned to a Participant Category at the time he or she becomes a Participant for a particular Plan Year. If a Participant thereafter incurs a change in status due to promotion, demotion,
reassignment or transfer, such Participant’s Reward Opportunity shall be automatically adjusted to correspond with the Reward Opportunity for the new Participant Category, such adjustment to be made on a pro rata basis for the balance of the
Plan Year effective with the first day of the month following such change in status, unless the Committee exercises its discretion to reduce Participant’s rights to a Reward for such Plan Year on a prorated basis corresponding to that portion
of the Plan Year during which he or she had a change in status. 
 3.3 No Right to Participate. Except as provided in Sections
3.1 and 3.2, no Participant or other employee of the Company or an Affiliate shall, at any time, have a right to participate in the Plan for any Plan Year, notwithstanding having previously participated in the Plan. 
 3.4 Plan Exclusive. No employee shall simultaneously participate in this Plan and in any other short-term incentive plan of the Company or
an Affiliate unless such employee’s participation in such other plan is approved by the CEO, or his delegate. 
 3.5 Consent to
Dispute Resolution. Participation in the Plan constitutes consent by the Participant to be bound by the terms and conditions of the Dispute Resolution Program 

  

 5 









 
which in substance requires that all disputes arising out of or in any way related to employment with the Company or its Affiliates, including any disputes
concerning the Plan, be resolved exclusively through such program, which includes binding arbitration as the last step. 
 ARTICLE IV

 ADMINISTRATION 
 Each Plan Year, the Committee shall establish the basis for payments under the Plan in relation to given Performance Goals, as more fully described in Article V hereof, and, following the end of each Plan Year, determine the actual Reward
payable for each Participant Category. The Committee shall construe and interpret the Plan, prescribe, amend and rescind rules, regulations and procedures relating to its administration and make all other determinations necessary or advisable for
administration of the Plan. Decisions of the Committee shall be conclusive and binding. Subject only to compliance with the express provisions hereof, the Committee may act in its sole and absolute discretion with respect to matters within its
authority under the Plan. 
 ARTICLE V 
 REWARD DETERMINATIONS 
 5.1 Performance Measures. A combination of Performance Measures
shall be used in determining Performance Goals for any Plan Year. 
 5.2 Performance Requirements. No later than the
first 90 days after the commencement of each Plan Year, (i) the Committee shall approve the Performance Measures applicable to certain Participants, and (ii) the Committee shall establish a Reward Schedule which aligns the level of
achievement of applicable Performance Goals with Reward Opportunities, such that the level of achievement of the pre-established Performance Goals at the end of the Plan Year will determine the actual Reward. 
 5.3 Reward Determinations. After the end of each Plan Year, the Committee shall determine the extent to which the Performance Goals have
been achieved, and the amount of the Reward shall be computed for each Participant in accordance with the Reward Schedule. 
  

 6 









 5.4 Reward Opportunities. The established Reward Opportunities may vary in relation to the
Participant Categories and within the Participant Categories. In the event a Participant changes Participant Categories during a Plan Year, the Participant’s Reward Opportunities shall be adjusted in accordance with the applicable provisions of
Section 3.2. 
 5.5 Discretionary Adjustments. Once established, Performance Goals will not be changed during the Plan
Year. However, if the Committee, in its sole and absolute discretion, determines that there has been (i) a change in the business, operations, corporate, or capital structure, (ii) a change in the manner in which business is conducted, or
(iii) any other material change or event which will impact one or more Performance Goals in a manner the Committee did not intend, then the Committee may, reasonably contemporaneously with such change or event, make negative adjustments to
reduce or eliminate the compensation that was due upon attainment of the Performance Goals as it shall deem appropriate and equitable. 
 ARTICLE VI 
 DISTRIBUTION OF REWARDS 
 6.1 Form and Timing of Payment. Except as otherwise provided below, the amount of each Reward shall be paid in a cash lump sum on the Payment Date. In the event of termination of a Participant’s
employment prior to the Payment Date for any reason other than death (in which case payment shall be made in accordance with the applicable provisions of Article VII), the amount of any Reward (or prorated portion thereof) payable pursuant to the
provisions of Sections 7.1 or 7.2 shall be paid in cash on the Payment Date, or as soon thereafter as practicable. 
 6.2 Excess
Remuneration. Notwithstanding the provisions of Section 6.1, to the extent that incentive compensation hereunder does not qualify as performance-based compensation pursuant to Section 162(m) of the Code with respect to a
Participant who is a “covered employee” for purposes of Section 162(m), the portion of a Reward which would otherwise cause such Participant’s compensation to exceed the limitation on the amount of compensation deductible by the
Company in any taxable year pursuant to such Section 162(m) 

  

 7 









 
shall automatically be deferred until such Participant is no longer a “covered employee.” In such case, interest shall be credited on the portion
of the Reward deferred for the period of the deferral as provided pursuant to the KBR Benefit Restoration Plan, as amended, or other applicable plan. 
 6.3 Elective Deferral. Nothing herein shall be deemed to preclude a Participant’s election to defer receipt of a percentage of his or her Reward beyond the time such amount would have been payable
hereunder pursuant to the KBR Elective Deferral Plan or other similar plan and in compliance with the requirements of Code Section 409A and related regulations and U.S. Department of Treasury pronouncements. 
 6.4 Tax Withholding. The Company or employing entity through which payment of a Reward is to be made shall have the right to deduct from
any payment hereunder any amounts that Federal, state, local or foreign tax laws require with respect to such payments. 
 ARTICLE VII

 TERMINATION OF EMPLOYMENT 
 7.1 Termination of Service During Plan Year. In the event a Participant’s employment is terminated prior to the last business day of a Plan Year for any reason other than death, normal retirement at or after age 65 or
disability (as determined under the Company’s Long Term Disability Plan), all of such Participant’s rights to a Reward for such Plan Year shall be forfeited unless the Committee shall determine that such Participant’s Reward for such
Plan Year shall be prorated based upon that portion of the Plan Year during which he or she was a Participant, in which case the prorated portion of the Reward shall be paid in accordance with the provisions of Section 6.1. In the case of death
during the Plan Year, the prorated amount of such Participant’s Reward shall be paid to the Participant’s estate, or if there is no administration of the estate, to the heirs at law, on the Payment Date, or as soon thereafter as
practicable. In the case of disability or normal retirement at or after age 65, the prorated amount of a Participant’s Reward shall be paid in accordance with the provisions of Section 6.1. 
  

 8 









 7.2 Termination of Service After End of Plan Year But Prior to the Payment Date. If a
Participant’s employment is terminated after the end of the applicable Plan Year, but prior to the Payment Date, for any reason other than termination for Cause, the amount of any Reward applicable to such Plan Year shall be paid to the
Participant in accordance with the provisions of Section 6.1, except in the case of death, in which case the amount of the Reward then unpaid shall be paid to such Participant’s estate, or if there is no administration of the estate, to
the heirs at law, as soon as practicable. 
 If a Participant’s employment is terminated for Cause, all of such Participant’s
rights to a Reward applicable to such Plan Year shall be forfeited. 
 ARTICLE VIII 
 RIGHTS OF PARTICIPANTS AND BENEFICIARIES 
 8.1 Status as a Participant or Beneficiary. Neither status as a Participant or Beneficiary shall be construed as a commitment that any Reward will be paid or payable under the Plan. 
 8.2 Employment. Nothing contained in the Plan, or in any document related to the Plan or to any Reward, shall confer upon any Participant
any right to continue as an employee or in the employ of the Company or an Affiliate or constitute any contract or agreement of employment for a specific term or interfere in any way with the right of the Company or an Affiliate to reduce such
person’s compensation, to change the position held by such person or to terminate the employment of such person, with or without cause. 
 8.3 Nontransferability. No benefit payable under, or interest in, this Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge and any such attempted action
shall be void and no such benefit or interest shall be, in any manner, liable for, or subject to, debts, contracts, liabilities or torts of any Participant or Beneficiary; provided, however, that, nothing in this Section 8.3 shall prevent
transfer (i) by will, (ii) by applicable laws of descent and distribution, or (iii) pursuant to an order that satisfies the requirements for a “qualified domestic relations order” as such 

  

 9 









 
term is defined in section 206(d)(3)(B) of ERISA and section 414(p)(1)(A) of the Code, including an order that requires distributions to an alternate payee
prior to a Participant’s “earliest retirement age” as such term is defined in section 206(d)(3)(E)(ii) of ERISA and section 414(p)(4)(B) of the Code. Any attempt at transfer, assignment or other alienation prohibited by the preceding
sentence shall be disregarded and all amounts payable hereunder shall be paid only in accordance with the provisions of the Plan. 
 8.4
Nature of Plan. No Participant, Beneficiary or other person shall have any right, title, or interest in any fund or in any specific asset of the Company or any Affiliate by reason of any Reward hereunder. There shall be no funding of any
benefits which may become payable hereunder. Nothing contained in the Plan (or in any document related thereto), nor the creation or adoption of the Plan, nor any action taken pursuant to the provisions of the Plan shall create, or be construed to
create, a trust of any kind or a fiduciary relationship between the Company or an Affiliate and any Participant, Beneficiary or other person. To the extent that a Participant, Beneficiary or other person acquires a right to receive payment with
respect to a Reward hereunder, such right shall be no greater than the right of any unsecured general creditor of the Company or other employing entity, as applicable. All amounts payable under the Plan shall be paid from the general assets of the
Company or employing entity, as applicable, and no special or separate fund or deposit shall be established and no segregation of assets shall be made to assure payment of such amounts. Nothing in the Plan shall be deemed to give any employee any
right to participate in the Plan except in accordance herewith. 
 ARTICLE IX 
 CORPORATE CHANGE 
 In the event of a Corporate Change, (i) with respect to
a Participant’s Reward Opportunity for the Plan Year in which the Corporate Change occurred, such Participant shall be entitled to an immediate cash payment equal to the maximum amount of Reward he or she would have been entitled to receive for
the Plan Year, prorated to the date of the Corporate Change; and (ii) with respect to a Corporate Change that occurs after the end of the Plan Year but prior to the Payment Date, a Participant shall be entitled to an immediate cash payment
equal to the Reward earned for such Plan Year. 
  

 10 









 ARTICLE X 
 AMENDMENT AND TERMINATION 
 Notwithstanding anything herein to the contrary, the Committee may, at
any time, terminate or, from time to time amend, modify or suspend the Plan; provided, however, that, without the prior consent of the Participants affected, no such action may adversely affect any rights or obligations with respect to any Rewards
theretofore earned for a particular Plan Year, whether or not the amounts of such Rewards have been computed and whether or not such Rewards are then payable, subject to the Committee’s express rights as set forth herein. 
 ARTICLE XI 
 MISCELLANEOUS

 11.1 Governing Law. The Plan and all related documents shall be governed by, and construed in accordance with, the laws
of the State of Texas, without giving effect to the principles of conflicts of law thereof, except to the extent preempted by federal law. The Federal Arbitration Act shall govern all matters with regard to arbitrability. 
 11.2 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, each provision shall be fully severable and the Plan shall be construed and enforced as if said illegal or invalid provision had never been included herein. 
 11.3 Successor. All obligations of the Company under the Plan shall be binding upon and inure to the benefit of any successor to the
Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. 
 11.4 Effective Date. This Plan shall be effective from and after January 1, 2007, and shall remain in effect until such time as it may
be terminated or amended pursuant to Article X. 
  

 11
