US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 1 PERFORMANCE AWARD AGREEMENT Grant Date:____________ Re: Performance Unit Grant I am pleased to inform you that KBR, Inc. (the “Company”) has granted you two classes of performance units (one class being referred to as the “Book-to-Bill Performance Units,” the other class being referred to as the “TSR Performance Units,” and the two classes collectively referred to as the “Performance Units”) under the Company’s Amended and Restated 2006 Stock and Incentive Plan, as amended and restated (the “Plan”), subject to the terms and conditions in the Plan and as set forth in this Performance Award Agreement, including any exhibits attached hereto (collectively, the “Agreement”) as follows: 1. Grant of Performance Units. The number of Book-to-Bill Performance Units granted to you as a Performance Award under the Plan is _______. Each Book-to-Bill Performance Unit shall have a target value of $1.00. The actual value, if any, of a Book-to-Bill Performance Unit at the end of the Performance Period (as defined in Exhibit A) will, subject to Paragraph 3 below, be determined based on the level of achievement during the Performance Period of the Book- to-Bill -related performance objectives set forth in Exhibit A hereto, which is made a part hereof for all purposes. The target number of TSR Performance Units granted to you as a Performance Award under the Plan is _______. Each TSR Performance Unit represents the right to receive one share of the Company’s common stock (“Stock”). The number of TSR Performance Units subject to this Agreement may be adjusted upward or downward in accordance with the level of achievement during the Performance Period of the TSR-related performance objectives set forth in Exhibit A hereto. You shall have no right to dividend equivalents with respect to any of the Performance Units. Eighty percent of each class of the Performance Units shall be “Tranche One PUs” and twenty percent of each class of the Performance Units shall be “Tranche Two PUs.” 2. Terms of Performance Units. (a) Vesting. Except as otherwise provided in subparagraphs (b) and (d) below, you will vest in the Performance Units earned (if any) for the Performance Period only if you are an employee of the Company or a Subsidiary on the date such earned Performance Units are paid, as provided in Paragraph 3 below. In addition, except as otherwise provided in subparagraphs (b) and (d) below, you shall, for no consideration, forfeit all of the Tranche Two PUs on

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 2 December 31, 2022, if the Committee that administers the Plan (the “Committee”) determines, in its sole discretion, that calendar year 2022 was not a successful year for the Company. Any such determination by the Committee shall be made on or before March 31, 2023. (b) Death, Disability or Retirement. Unless otherwise provided in an agreement pursuant to Paragraph 14, if you cease to be an employee of the Company or a Subsidiary as a result of (i) your death, (ii) your permanent disability (disability being defined as being physically or mentally incapable of performing either your usual duties as an employee or any other duties as an employee that the Company reasonably makes available and such condition is likely to remain continuously and permanently, as determined by the Company or employing Subsidiary), or (iii) your retirement with the approval of the Committee (with such approval to be granted or withheld in the sole discretion of the Committee), then, in any such case, a prorata portion of each class of your Performance Units that become “earned,” if any, as provided in Exhibit A, will become vested; provided, however, that if the Tranche Two PUs have been forfeited pursuant to the last two sentences of subparagraph (a) above prior to the occurrence of an event described in clause (i), (ii) or (iii) of this sentence, then the Tranche Two PUs shall remain forfeited, no portion of the Tranche Two PUs will vest upon the occurrence of any such event, and the prorata portion of each class of your Performance Units that become “earned”, if any, and that may become vested pursuant to this sentence shall be determined based solely upon the Tranche One PUs. The “prorata portion” that becomes vested shall be a fraction, the numerator of which is the number of days in the Performance Period in which you were an employee of the Company or a Subsidiary and the denominator of which is the total number of days in the Performance Period. If your termination for the above reasons is after the end of the Performance Period but before payment of the Performance Units earned, if any, for such Performance Period, you will be fully vested in any such earned Performance Units that have not yet been forfeited and which are still outstanding. (c) Other Terminations. If you terminate employment from the Company and its Subsidiaries for any reason other than as provided in subparagraph (b) above or subparagraph (d) below or if you breach any of the covenants set forth in Paragraph 6, all unvested Performance Units held by you shall be forfeited without payment immediately upon such termination or the occurrence of such breach (as applicable). (d) Corporate Change. Notwithstanding any other provision hereof, unless otherwise provided in an agreement pursuant to Paragraph 14, your Performance Units shall become fully vested at the maximum earned percentage provided in Exhibit A upon your Involuntary Termination or termination for Good Reason within two years following a Corporate Change (as provided in the Plan) (a “Double Trigger Event”) during the Performance Period; provided, however, that if the Tranche Two PUs have been forfeited pursuant to the last two sentences of subparagraph (a) above prior to the occurrence of a Double Trigger Event, then the Tranche Two PUs shall

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 3 remain forfeited, no portion of the Tranche Two PUs will vest upon the occurrence of the Double Trigger Event, and the portion of your Performance Units that become vested pursuant to this sentence shall be determined based solely upon the Tranche One PUs. If a Double Trigger Event occurs after the end of the Performance Period and prior to payment of the earned Performance Units, you will be 100% vested in your earned Performance Units that have not yet been forfeited and which are still outstanding upon the Double Trigger Event and payment will be made in accordance with the results achieved for the Performance Period ended as provided in Exhibit A. For purposes of this Agreement, employment with the Company includes employment with a Subsidiary. For the avoidance of doubt, it is expressly provided that you shall be considered to have terminated employment with the Company at the time of the termination of the “Subsidiary” status under the Plan of the entity or other organization that employs you. 3. Payment of Vested Performance Units. As soon as administratively practicable after the end of the Performance Period, but no later than the March 15th following the end of the Performance Period, or with respect to a Double Trigger Event occurring prior to the end of the Performance Period, the date of the Double Trigger Event (but no later than the March 15th following the calendar year in which occurs the date of the Double Trigger Event), you shall be entitled to receive from the Company (a) a payment in cash equal to the product of the “Average Book-to-Bill Payout Ratio” (as defined in Exhibit A) and the sum of the target values of your vested Book-to-Bill Performance Units and (b) a payment in a number of shares of Stock (rounded to the nearest wholes share) equal to the product of the “TSR Payout Percentage” (as determined in accordance with Exhibit A) and your vested target TSR Performance Units; provided, however, that such payment amounts may be reduced, but not increased, by any amount (including a reduction resulting in a payment of $0 and zero shares of Stock) in the sole discretion of the Committee and, in the case of any such reduction, the Committee shall determine the allocation of such reduction between the payments otherwise provided for in clauses (a) and (b) above (provided that any such discretion to reduce such payment amounts may not be exercised by the Committee at any time after the occurrence of a Corporate Change). Except as provided in Exhibit A with respect to a Double Trigger Event, if the performance thresholds set forth in Exhibit A with respect to a class of Performance Units are not met, no payment shall be made with respect to such class of Performance Units, whether or not vested. Notwithstanding the foregoing, in no event may the amount paid to you by the Company in any year with respect to Performance Units earned hereunder exceed any applicable limit under Article V of the Plan. Further, the Company shall not be obligated to deliver any shares of Stock if counsel to the Company determines that such delivery would violate any applicable law or any rule or regulation of any governmental authority or any rule or regulation of, or agreement of the Company with, any securities exchange or association upon which the Stock is listed or quoted. 4. Recovery of Payment of Vested Performance Units. If, within the three-year period beginning on the date that you receive a payment pursuant to Paragraph 3, the basis upon

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 4 which the performance measurements were achieved during any calendar year of the Performance Period changes because of any restatement of or revision to the Company’s financial results, shareholder return, or any other performance measure for the same calendar year, regardless of fault, and the value of the Performance Units earned at the end of the Performance Period is determined to have resulted in an overpayment based on such calendar year’s restated or revised financial results, shareholder return or other performance measure, the Committee may, in its sole and absolute discretion, seek recovery of the amount of the Performance Award determined to be an overpayment or hold the overpayment as debit against future Awards for up to a three-year period following the end of the Performance Period. In addition, the Company may seek recovery of any benefits provided to you under this Agreement if such recovery is required by any clawback policy adopted by the Company, which may be amended from time to time, including, but not limited to, any clawback policy adopted to satisfy the minimum clawback requirements adopted under the Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act of 2010 and the regulations thereunder or any other applicable law or securities exchange listing standard. The Company reserves the right, without your consent, to adopt any such clawback policy, including, but not limited to, such clawback policies applicable to this Performance Award with retroactive effect. 5. Limitations Upon Transfer. All rights under this Agreement shall belong to you and may not be transferred, assigned, pledged, or hypothecated in any way (whether by operation of law or otherwise), other than by will or the applicable laws of descent and distribution or, if you are exclusively subject to the laws of the United States, pursuant to a “qualified domestic relations order” (as defined by the Code), and shall not be subject to execution, attachment, or similar process. Upon any attempt to transfer, assign, pledge, hypothecate, or otherwise dispose of such rights contrary to the provisions in this Agreement or the Plan, or upon the levy of any attachment or similar process upon such rights, such rights shall immediately become null and void. 6. Non-Competition; Non-Solicitation; Non-Disclosure. (a) Following the date you enter into this Agreement, the Company and/or its Subsidiary(ies) shall provide you access to Confidential Information (as defined below). Such Confidential Information shall be for use only during your employment with the Company, and as an express incentive for the Company to enter into this Agreement and to grant to you the Performance Units (which grant, you acknowledge, shall further align your interests with the long-term business interests of the Company and its Subsidiaries) and provide you with Confidential Information, you have voluntarily agreed to the covenants set forth in this Paragraph 6. You agree and acknowledge that the limitations and restrictions set forth herein, including geographical and temporal restrictions on certain competitive activities, are reasonable in all respects, do not interfere with public interests, will not cause you undue hardship, and are material and substantial parts of this Agreement intended and necessary to prevent unfair competition and to protect the Company’s and its Subsidiaries’ trade secrets and other Confidential Information, goodwill and legitimate business interests.

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 5 (b) During the Prohibited Period (as defined below), you shall not, without the prior written approval of the Company, directly or indirectly, for yourself or on behalf of or in conjunction with any other person or entity of any nature: (i) engage in or participate within the Market Area (as defined below) in competition with the Company or any of its Subsidiaries in any aspect of the Business (as defined below), which prohibition shall prevent you from directly or indirectly: (A) owning, managing, operating, or being an officer or director of, any business that competes with the Company or any of its Subsidiaries in the Market Area, or (B) joining, becoming an employee or consultant of, or otherwise being affiliated with, any person or entity engaged in, or planning to engage in, the Business in the Market Area in competition, or anticipated competition, with the Company or any of its Subsidiaries in any capacity (with respect to this clause (B)) in which your duties or responsibilities are the same as or similar to the duties or responsibilities that you had on behalf of the Company or any of its Subsidiaries, or involve direct or indirect oversight over such duties or responsibilities; (ii) appropriate any Business Opportunity of, or relating to, the Company or any of its Subsidiaries located in the Market Area; (iii) solicit, canvass, approach, encourage, entice or induce any customer or supplier of the Company or any of its Subsidiaries for whom or which you had responsibility in the final 12 months prior to the termination of your employment with the Company to cease or lessen such customer’s or supplier’s business with the Company or any of its Subsidiaries; or (iv) solicit, canvass, approach, encourage, entice or induce any employee or contractor of the Company or any of its Subsidiaries to terminate his, her or its employment or engagement with the Company or any of its Subsidiaries. (c) Notwithstanding any other provision of this Agreement: (i) the covenants set forth in this Paragraph 6 shall not apply to restrict any of your activities within the State of California, including if you are a California resident; and (ii) if prohibited by any applicable law regarding non-competition restrictions in Washington, D.C., the covenants set forth in Paragraphs 6(b)(i) and 6(b)(ii) shall not apply with respect to any activities conducted within (including individuals’ performance of work in) Washington, D.C.; provided, however, for the avoidance of doubt, the foregoing exceptions under this Paragraph 6(c) shall not limit any other obligations that you owe to the Company or any of

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 6 its Subsidiaries under any other agreements or applicable laws, including (without limitation) with respect to the protection of Confidential Information. (d) If you are an attorney at law or licensed lawyer in any jurisdiction, none of the restrictions set forth in this Paragraph 6 shall be interpreted or applied in a manner to prevent or restrict you from practicing law, as it is the intent of this Paragraph 6 to create certain limitations on your business activities only, and not to create limitations that would restrict you from practicing law. If you are an attorney at law or licensed to practice law, you acknowledge and agree that, both during your employment with the Company and thereafter, you shall be bound by all ethical and professional obligations (including those with respect to conflicts of interest and confidentiality) that may arise from your provision of legal services to, and acting as legal counsel for, the Company and (as applicable) its Subsidiaries. (e) You agree, both during and after your employment with the Company, not to use or disclose any Confidential Information other than for the benefit of the Company or its Subsidiaries in the course of your duties for the Company or its applicable Subsidiary. All trade secrets, non-public information, designs, ideas, concepts, improvements, product developments, discoveries and inventions, whether patentable or not, that are conceived, made, developed or acquired by or disclosed to you, individually or in conjunction with others, in connection with your employment with the Company or otherwise during the time that you are or have been employed or engaged by the Company or any of its Subsidiaries (whether during business hours or otherwise and whether on the Company’s or its Subsidiaries’ premises or otherwise), that relate to the Companies’ or its Subsidiaries’ businesses or properties, products or services (including all such information relating to corporate opportunities, operations, future plans, methods of doing business, business plans, formulas, strategies for developing business and market share, research, financial and sales data, pricing terms, evaluations, opinions, interpretations, acquisition prospects, the identity of customers or their requirements, research and development information, the identity of key contacts within customers’ organizations or within the organization of acquisition prospects, or marketing and merchandising techniques, prospective names and marks) is defined as “Confidential Information”. For purposes of this Agreement, Confidential Information shall not include any information that (i) is or becomes generally available to the public other than as a result of a disclosure or wrongful act of you or your agents; (ii) was available to you on a non-confidential basis before its disclosure by the Company or any of its Subsidiaries; or (iii) becomes available to you on a non-confidential basis from a source other than the Company or any of its Subsidiaries; provided, that such source is not bound by a confidentiality agreement with, or other obligation with respect to confidentiality to, the Company or any of its Subsidiaries. (f) Notwithstanding the foregoing Paragraph 6(e), nothing in this Agreement shall prohibit or restrict you from lawfully (i) initiating communications directly with, cooperating with, providing information to, causing information to be provided to,

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 7 or otherwise assisting in an investigation by, any governmental authority (in each instance regarding a possible violation of any law); (ii) responding to any inquiry or legal process directed to you from any such governmental authority; (iii) testifying, participating or otherwise assisting in an action or proceeding by any such governmental authority relating to a possible violation of law or (iv) making any other disclosures that are protected under the whistleblower provisions of any applicable law. Additionally, pursuant to the federal Defend Trade Secrets Act of 2016, you shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (x) is made (A) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney and (B) solely for the purpose of reporting or investigating a suspected violation of law; (y) is made to your attorney in relation to a lawsuit for retaliation against you for reporting a suspected violation of law or (z) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Nothing in this Agreement requires you to obtain prior authorization before engaging in any conduct described in this paragraph, or to notify the Company or any of its Subsidiaries that you have engaged in any such conduct. (g) Because of the difficulty of measuring economic losses to the Company and its Subsidiaries as a result of a breach or threatened breach of the covenants set forth in this Paragraph 6, and because of the immediate and irreparable damage that would be caused to the Company and its Subsidiaries for which they would have no other adequate remedy, the Company and each of its Subsidiaries shall be entitled to enforce the foregoing covenants, in the event of a breach or threatened breach, by injunctions and restraining orders from any court of competent jurisdiction, without the necessity of showing any actual damages or that money damages would not afford an adequate remedy, and without the necessity of posting any bond or other security. The aforementioned equitable relief shall not be the Company’s or its Subsidiaries’ exclusive remedy for a breach but instead shall be in addition to all other rights and remedies available to the Company and each of its Subsidiaries at law and equity. (h) The covenants in this Paragraph 6, and each provision and portion hereof, are severable and separate, and the unenforceability of any specific covenant (or portion thereof) shall not affect the provisions of any other covenant (or portion thereof). Moreover, in the event any arbitrator or court of competent jurisdiction shall determine that the scope, time or territorial restrictions set forth are unreasonable, then it is the intention of the parties that such restrictions be enforced to the fullest extent which such arbitrator or court deems reasonable, and this Agreement shall thereby be reformed. (i) The following terms shall have the following meanings: (i) “Business” shall mean the business and operations that are the same or similar to those performed by the Company and any of its Subsidiaries for

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 8 which you provide services or about which you obtain Confidential Information during your employment with the Company. (ii) “Business Opportunity” shall mean any commercial, investment or other business opportunity relating to the Business. (iii) “Market Area” shall mean: (i) during that portion of the Prohibited Period that exists during which you are employed by the Company, any geographic area or market where you provide, or have provided, services to the Company or any of its Subsidiaries; and (ii) during that portion of the Prohibited Period that exists following the date that you are no longer employed by the Company, any geographic area or market where you provided services to the Company or any of its Subsidiaries as of the date you are no longer employed by the Company or during the 12 months prior to such date. (iv) “Prohibited Period” shall mean the period during which you are employed by the Company and continuing for a period of 12 months following the date that you are no longer employed by the Company; provided, however, with respect to a termination of employment with the Company on or after the date upon which a Corporate Change occurs, the Prohibited Period shall end on the date of such termination of employment with respect to the obligations under Paragraphs 6(b)(i) and 6(b)(ii). 7. Withholding of Tax. You acknowledge that, regardless of any action taken by the Company or, if different, your employer (the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to your participation in the Plan and legally applicable to you (“Tax-Related Items”), is and remains your responsibility and may exceed the amount actually withheld by the Company or the Employer. You further acknowledge that the Company and/or the Employer (1) do not make representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Performance Units including, but not limited to, the grant, vesting or payout of the Performance Units, the subsequent sale of any Stock that may be issued under this Agreement and the receipt of any dividends; and (2) do not commit to structure the terms of the Performance Units or any aspect of the Performance Units to reduce or eliminate your liability for Tax-Related Items or achieve any particular tax result. Further, if you are subject to Tax-Related Items in more than one jurisdiction, you acknowledge that the Company and/or Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction. Prior to any relevant taxable or tax withholding event, as applicable, you agree to make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax- Related Items. In this regard, you authorize the Company and/or your Employer or their respective agents, at their discretion, to satisfy any applicable withholding obligations with regard to all Tax-Related Items by one or a combination of the following: (a) withholding

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 9 from your wages or other cash compensation paid to you by the Company and/or your Employer, or (b) withholding from the payout of the Performance Units; provided, however, that if you receive shares of Stock pursuant to Paragraph 3, then withholding with respect to such shares shall be in the form of shares of Stock. Depending on the withholding method, the Company may withhold or account for Tax- Related Items by considering applicable minimum statutory withholding amounts or other applicable withholding rates, including maximum applicable rates, in which case you may receive a refund of any over-withheld amount in cash and will have no entitlement to the Performance Units or, if applicable, any Stock that may have been issuable under this Agreement. You agree to pay the Company or the Employer, including through withholding from your wages or other cash compensation paid to you by the Company or the Employer, any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of your participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to deliver the cash settlement, or any other form of pay-out for the Performance Units, if you fail to comply with your obligations in connection with the Tax-Related Items. Notwithstanding the preceding provisions of this Paragraph 7, your liability with respect to Tax-Related Items shall be subject to any international tax assignment agreement then in effect between you and the Company, the Employer or any of their respective affiliates or any tax policies or procedures applicable to your home country, and in the event of any conflict between the terms of this Paragraph 7 and the terms of such international tax assignment agreement or such tax policies or procedures, the terms of such international tax assignment agreement or such tax policies or procedures, as applicable, shall control. 8. Nature of Grant. In accepting the Performance Units, you acknowledge, understand and agree that: (a) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time, to the extent permitted by the Plan; (b) the grant of the Performance Units is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of Performance Units, or benefits in lieu of Performance Units, even if Performance Units have been granted in the past; (c) all decisions with respect to future Performance Units or other grants, if any, will be at the sole discretion of the Company; (d) the grant of Performance Units and your participation in the Plan shall not create a right to employment or be interpreted as forming an employment or service contract with the Company, your Employer, or any Subsidiary and shall not interfere with the ability of the Employer to terminate your employment or service relationship (if any); (e) you are voluntarily participating in the Plan; (f) the Performance Units, and the income and value of same, are not intended to replace any pension rights or compensation; (g) the Performance Units, and the income and value of same, are not part of normal or expected compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, holiday-pay, bonuses, long-service awards, leave-related payments, pension or retirement benefits or similar mandatory payments; (h) the future value of the Performance Units and any Stock that may be issued under this Agreement is unknown, indeterminable and cannot be predicted with certainty;

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 10 (i) no claim or entitlement to compensation or damages shall arise from the forfeiture of the Performance Units resulting from you ceasing to provide employment or other services to the Company or your Employer (for any reason whatsoever whether or not later found to be invalid or in breach of employment laws in the jurisdiction where you are employed or the terms of your employment agreement, if any); (j) in the event of involuntary termination of your active employment or other services (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where you are employed or the terms of your employment agreement, if any), unless otherwise provided in this Agreement or determined by the Company, your right to vest in the Performance Units under the Plan, if any, will terminate effective as of the date that you are no longer actively providing services and will not be extended by any notice period (e.g., active services would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where you are employed or the terms of your employment agreement, if any), except as expressly provided herein, and that the Company shall have the exclusive discretion to determine when you are no longer actively providing services for purposes of the Performance Units (including whether you may still be considered to be providing services while on an approved leave of absence); (k) unless otherwise provided in the Plan or by the Company in its discretion, the Performance Units and the benefits evidenced by this Agreement do not create any entitlement to have the Performance Units or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting the shares of the Company; (l) unless otherwise agreed with the Company, the Performance Units, and the income and value of same, are not granted as consideration for, or in connection with, services you may provide as a director of a Subsidiary; (m) if you are requested to make repayment under Paragraph 4, you will make repayment immediately; and (n) the following provisions apply only if you are providing services outside the United States: (i) the Performance Units, and the income and value of same, are not part of normal or expected compensation or salary for any purpose; and (ii) neither the Company, the Employer nor any Subsidiary shall be liable for any foreign exchange rate fluctuation between your local currency and the United States Dollar that may affect the value of the Performance Units or the subsequent payout of the Performance Units or sale of any shares of Stock that may be issued under this Agreement. 9. No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding your participation in the Plan. You should consult with your own personal tax, legal and financial advisors regarding your participation in the Plan before taking any action related to the Plan. 10. Data Privacy. (a) Declaration of Consent. By accepting the Performance Units via the Company’s acceptance procedure, you are declaring that you agree with the data processing practices described herein and consent to the collection, processing and use of Data by the Company and the transfer of Data to the recipients mentioned below,

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) 11 including recipients located in countries which may not have a similar level of protection from the perspective of the data protection laws in your country. (b) Data Collection and Usage. The Company and the Employer may collect, process and use certain personal information about you, including, but not limited to, your name, home address and telephone number, email address, date of birth, social insurance number, passport or other identification number, salary, nationality, job title, any shares or directorships held in the Company and details of all Performance Units, whether vested or unvested, held in your favor (“Data”), for the purposes of implementing, administering and managing the Plan. The legal basis, where required, for the processing of Data is your consent. (c) Plan Administration Service Providers. The Company may select a service provider to assist in the implementation, administration and management of the Plan and the Company may share Data with such service provider. In such case, you may be asked to agree on separate terms and data processing practices with the service provider(s), which will be a condition of your ability to participate in the Plan. (d) International Data Transfers. The Company is based in the United States, which means that it will be necessary for Data to be transferred to, and processed in, the United States. You understand that your country may have enacted data privacy laws that are different from the laws of the United States. As a result, in the absence of appropriate safeguards such as standard data protection clauses, the processing of your Data in the United States or, as the case may be, other countries might not be subject to substantive data processing principles or supervision by data protection authorities. In addition, you might not have enforceable rights regarding the processing of your Data in such countries. The Company’s legal basis for the transfer of Data is your consent. (e) Data Retention. The Company will hold and use the Data only as long as is necessary to implement, administer and manage your participation in the Plan, or as required to comply with legal or regulatory obligations, including under tax, labor and exchange control laws. (f) Voluntariness and Consequences of Consent Denial or Withdrawal. Participation in the Plan is voluntary and you are providing the consents herein on a purely voluntary basis. You understand that you may withdraw consent at any time with future effect for any or no reason. If you do not consent, or if you later seek to revoke your consent, your salary from or employment and career with the Employer will not be affected; the only consequence of refusing or withdrawing consent is that the Company would not be able to offer Performance Units to you or administer or maintain your participation in the Plan. (g) Data Subject Rights.

This Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company or upon any person lawfully claiming under you. 12. Modification. Except to the extent permitted by the Plan, any modification of this Agreement will be effective only if it is in writing and signed by each party whose rights hereunder are affected thereby. 13. Plan Controls. This grant is subject to the terms of the Plan, which are hereby incorporated by reference. In the event of a conflict between the terms of this Agreement and the Plan, the Plan shall be the controlling document. Capitalized terms used herein or in Exhibit A and not otherwise defined herein or in Exhibit A shall have the meaning ascribed to them in the Plan. 14. Other Agreements. The terms of this Agreement shall be subject to and governed by, and shall not modify, the terms and conditions of any employment, severance, and/or change- in-control agreement between the Company (or a Subsidiary) and you (“Other Agreement”), except that, notwithstanding anything in such Other Agreement to the contrary, any normal retirement age of 65 or other retirement-based vesting, payment or benefit provisions in such Other Agreement shall be of no force or effect for all purposes of the Performance Units granted under this Agreement. 15.

You hereby consent to receive such documents by electronic delivery and agree to participate in the Plan through an on-line or electronic system established and maintained by the Company or a third party designated by the Company. 16. Severability. If one or more of the provisions of this Agreement shall be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby and the invalid, illegal or unenforceable provisions shall be deemed null and void; however, to the extent permissible by law, any provisions which could be deemed null and void shall first be construed, interpreted or revised retroactively to permit this Agreement to be construed so as to xxxxxx the intent of this Agreement and the Plan.

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT A) A-1 EXHIBIT A To Performance Award Agreement Performance Goals Except as otherwise provided in the Agreement, the provisions of this Exhibit A shall determine the extent, if any, that the Performance Units become “earned” and payable. I. Performance Period The Performance Period shall be the period beginning January 1, 2022, and ending December 31, 2024. II. Total Shareholder Return (“TSR”) The payment of a TSR Performance Unit will be determined based on the comparison of (i) the average of the TSRs (as defined below) of the Company’s common stock measured at the end of each calendar quarter during the Performance Period, with each quarter’s TSR indexed back to the beginning of the calendar year in which such calendar quarter occurs, to (ii) the average of the TSRs of each of the common stocks of the members of the Peer Group measured at the end of each calendar quarter during the Performance Period, with each quarter’s TSR indexed back to the beginning of the calendar year in which such calendar quarter occurs. “TSR” or “Total Shareholder Return” shall mean, with respect to a calendar quarter, the change in the price of a share of common stock from the beginning of the calendar year in which such calendar quarter occurs (as measured by the simple average of the closing prices of a share of such stock trading during regular trading hours for the last twenty trading days preceding the beginning of such calendar year) until the end of the applicable calendar quarter to be measured during the Performance Period (as measured by the simple average of the closing prices of a share of such stock trading during regular trading hours for the last twenty trading days of the calendar quarter), adjusted to reflect the reinvestment of dividends (if any) through the purchase of common stock at the closing price on the corresponding dividend payment date, which shall be the ex-dividend date, and rounded to the first decimal place. Dividends per share paid other than in the form of cash shall have a value equal to the amount of such dividends reported by the issuer to its shareholders for purposes of Federal income taxation. A. Average TSR The average TSR for a company for the Performance Period shall be the sum of the TSRs of the company measured at the end of each calendar quarter during the Performance Period, divided by 12. The average TSR for a company during the Performance Period shall be calculated based on the following formula:

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT A) A-2 2022 TSR Formula - Sustained Performance q=12 Average indexed performance =  (xq / x) q=1 12 where: x = share price at beginning of calendar year in which the applicable calendar quarter occurs (measured by simple average of the closing prices of a share trading during regular trading hours for the last twenty trading days preceding the beginning of such calendar year) xq = closing share price at the end of each quarter (measured by simple average of the closing prices of a share trading during regular trading hours for the last twenty trading days of such calendar quarter, and adjusted for dividends paid (where the dividend payment date is the ex- dividend date)) q = quarter number (1 through 12) Example 1: Date Share price * Index (x) (xq / x) 1/1/2022 $ 20.00 3/31/2022 $ 22.00 110.0 6/30/2022 $ 24.00 120.0 9/30/2022 $ 21.00 105.0 12/31/2022 $ 20.00 100.0 3/31/2023 $ 18.00 90.0 6/30/2023 $ 22.00 110.0 9/30/2023 $ 25.00 125.0 12/31/2023 $ 28.00 140.0 3/31/2024 $ 31.00 110.7 6/30/2024 $ 33.00 117.9 9/30/2024 $ 30.00 107.1 12/31/2024 $ 28.00 100.0 q=12  (xq / x) = 1,335.7 q=1 q=12  (xq / x) = 111.3 q=1 12 * Average price adjusted for dividends paid in the period, where the dividend payment date is the ex-dividend date.

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT A) A-3 B. Peer Group and TSR Payout Once the average TSR for the Company during the Performance Period is calculated, the average TSR for each company in the Peer Group shall be calculated. The Peer Group shall consist of the following companies (including KBR, Inc.): Booz Xxxxx Xxxxxxxx Holding Corporation Leidos Holdings, Inc. CACI International Inc ManTech International Corporation Fluor Corporation Xxxxxxx Corporation Xxxxxx Engineering Group Inc. Science Applications International Corporation No company shall be added to, or removed from, the Peer Group during the Performance Period, except that a company shall be removed from the Peer Group if during such period (i) such company ceases to maintain publicly available statements of operations prepared in accordance with GAAP, (ii) such company is not the surviving entity in any merger, consolidation, or other reorganization (or survives only as a subsidiary of an entity other than a previously wholly owned entity of such company), or (iii) such company sells, leases, or exchanges all or substantially all of its assets to any other person or entity (other than a previously wholly owned entity of such company). If one or more Peer Group companies are removed from the Peer Group, then the percentiles and TSR payouts will adjust for the change in “n” of the formula provided below; provided, however, that the adjustment must require at least a 90.0 percentile to receive the maximum TSR payout and at least a 20.0 percentile to receive the threshold TSR payout. After the average TSR is determined for the Company and each company in the Peer Group, the Company’s average TSR rank among the average TSRs for the Peer Group for the Performance Period and the Company’s applicable “TSR Payout Percentage” shall be determined by the following formula:

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT A) A-4 TSR Peer Group Percentile and TSR Payout Percentage Table Threshold Target Maximum Percentile <20% 20% 50% ≥90% TSR Payout Percentage 0% 25% 100% 200% LTI TSR Calculation Method Ranking Percentile * TSR Payout Percentage** Maximum 1 100.0% 200.0% 2 87.5% 193.8% 3 75.0% 162.5% 4 62.5% 131.3% Target 5 50.0% 100.0% 6 37.5% 68.8% Threshold 7 25.0% 37.5% 8 12.5% 0.0% 9 0.0% 0.0% * Rounded to 1 decimal place. ** For a Percentile ranking between Threshold and Target or Target and Maximum, the TSR Payout Percentage earned shall be determined by linear interpolation between maximum and threshold based on the Percentile ranking achieved. Rounded to 1 decimal place. Percentile for TSR purposes Percentile = (n - r) * 100% (n - 1) where: n = number of Peer Group companies (including KBR) r = KBR ranking in the list of companies (including KBR) Example 1 Example 3 KBR ranked 2nd out of 9 companies KBR ranked 3rd out of 8 companies (9 - 2) * 100% = 87.5% (8 - 3) * 100% = 71.4% (9 - 1) (8 - 1) Example 2 Example 4 KBR ranked 4th out of 9 companies KBR ranked 5th out of 7 companies (9 - 4) * 100% = 62.5% (7 - 5) * 100% = 33.3% (9 - 1) (7 - 1)

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT A) A-5 The TSR Payout Percentage and related payout shall be subject to reduction as provided in Paragraph 3 of the Agreement. Notwithstanding any of the foregoing, (a) unless otherwise provided in an agreement pursuant to Paragraph 14 of the Agreement, the TSR Payout Percentage shall equal 200% for payment in connection with a Double Trigger Event as provided in Paragraph 2(d) of the Agreement, and (b) if on the Grant Date you are an employee of the Company or any employing Subsidiary of the Company who is either the Company’s Chief Executive Officer or a direct report to the Company’s Chief Executive Officer and the Company’s average TSR (as determined pursuant to Part II.A. of this Exhibit A) at the end of the Performance Period is negative (i.e., an index below 100), then no payment hereunder with respect to the TSR performance measure will exceed the Target (100%) payout under the TSR Peer Group Percentile and TSR Payout Percentage Table above; provided, however, that this clause (b) shall not apply if, pursuant to the first sentence of Paragraph 2(d) of the Agreement, your outstanding Performance Units become fully vested at the maximum earned percentage provided in Exhibit A (200%) upon a Double Trigger Event occurring during the Performance Period. III. Book-to-Xxxx X. Book-to-Bill Determinations in General The payment of a Book-to-Bill Performance Unit will be determined based on the Average Book-to-Bill Payout Ratio as determined under Part III. of this Exhibit A. For purposes of Part III. of this Exhibit A, the following terms shall have the following meanings: “Average Book-to-Bill Payout Ratio” means the quotient obtained by dividing (i) the sum of the Book-to-Bill Payout Ratios for each of the three calendar years in the Performance Period by (ii) three. “Book-to-Bill Payout Ratio” means, with respect to a calendar year during the Performance Period, the amount determined in accordance with the following table: Threshold Target Maximum Book-to-Bill Ratio for the calendar year ˂ Threshold Ratio for the calendar year Threshold Ratio for the calendar year Target Ratio for the calendar year ≥Maximum Ratio for the calendar year Book-to-Bill Payout Ratio for the calendar year* 0% 25% 100% 200% * If the Book-to-Xxxx Xxxxx for the calendar year is between the Threshold Ratio and the Target Ratio under the first row of the table above, then the Book-to-Bill Payout Ratio for such calendar year shall be determined by linear interpolation between Threshold (25%)

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT A) A-6 and Target (100%) based on the Book-to-Bill Ratio result. If the Book-to-Bill Ratio for the calendar year is between the Target Ratio and the Maximum Ratio under the first row of the table above, then the Book-to-Bill Payout Ratio for such calendar year shall be determined by linear interpolation between Target (100%) and Maximum (200%) based on the Book-to-Bill Ratio result. Each Book-to-Bill Payout Ratio determined by linear interpolation shall be rounded to one decimal place. “Book-to-Bill Ratio” means, with respect to a calendar year, the quotient obtained by dividing (i) the aggregate dollar amount of the Company’s and its consolidated subsidiaries new orders for projects awarded during such year (which shall include, without limitation, new projects for such year, options exercised during such year with respect to projects (including new projects), and the expansion during such year of the scope of projects (including new projects); however, any contraction during such year of the scope of a project (including a new project) shall reduce the amount described in this clause (i)), by (ii) the aggregate dollar amount of the Company’s and its consolidated subsidiaries revenues for projects completed during such calendar year. The Book-to-Bill Ratio for each calendar year shall be determined by the Committee in its sole discretion. “Maximum Ratio” means, with respect to a calendar year during the Performance Period, a Book-to-Xxxx Xxxxx established by the Committee as the Maximum Ratio for such calendar year, which ratio shall be greater than the Target Ratio established by the Committee for such calendar year. “Target Ratio” means, with respect to a calendar year during the Performance Period, a Book-to-Xxxx Xxxxx established by the Committee as the Target Ratio for such calendar year, which ratio shall be greater than the Threshold Ratio and less than the Maximum Ratio established by the Committee for such calendar year. “Threshold Ratio” means, with respect to a calendar year during the Performance Period, a Book-to-Xxxx Xxxxx established by the Committee as the Threshold Ratio for such calendar year, which ratio shall be less than the Target Ratio established by the Committee for such calendar year. B. Determination of the “Earned” Value of Book-to-Bill Performance Units The “target” value of a Book-to-Bill Performance Unit is $1.00; its maximum value is $2.00 per unit, and its minimum value will be zero per unit. The value of an “earned” Book-to-Bill Performance Unit shall be determined by multiplying its “target” value of $1.00 by the Average Book-to-Bill Payout Ratio for the Performance Period, subject to reduction as provided in Paragraph 3 of the Agreement. Notwithstanding the foregoing, unless otherwise provided in an agreement pursuant to Paragraph 14 of the Agreement, the Average Book-to-Bill Payout Ratio shall be deemed to have been met at the maximum level (200%) in connection with a Double Trigger Event as provided in Paragraph 2(d) of the Agreement.

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT A) A-7 IV. Adjustments to Performance Measurements for Significant Events If, after the beginning of the Performance Period, there is a change in accounting standards required by the Financial Accounting Standards Board, the performance results shall be adjusted by the Company’s independent accountants as appropriate to disregard such change. In addition, the results of the Company or a peer group company shall be adjusted to reflect any stock splits or other events described in Article XIII of the Plan. V. Committee Certification As soon as reasonably practical following the end of the Performance Period, but in no event later than the March 15th following the end of the Performance Period, the Committee shall review and determine the performance results for the Performance Period and certify those results in writing. No Performance Units earned and vested shall be payable prior to the Committee’s certification; provided, however, Committee certification shall not apply in the event of a Double Trigger Event, unless otherwise provided in an agreement pursuant to paragraph 14 of the Agreement.

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT B) B-1 EXHIBIT B KBR, INC. Terms and Conditions of Performance Unit Grant SPECIAL PROVISIONS OF PERFORMANCE UNITS IN CERTAIN COUNTRIES This Exhibit B includes special country-specific terms that apply to residents in countries listed below. This Exhibit B is part of the Agreement. Unless otherwise provided below, capitalized terms used but not defined herein shall have the same meanings assigned to them in the Plan and the Agreement. This Exhibit B also includes information regarding exchange controls and certain other issues of which you should be aware with respect to your participation in the Plan. The information is based on the exchange control and other laws in effect in the respective countries as of January 2022. Such laws are often complex and change frequently. Note certain individual exchange control reporting requirements may apply upon vesting of the Performance Units and results may be different based on the particular facts and circumstances. As a result, the Company strongly recommends that you do not rely on the information noted herein as the only source of information relating to the consequences of your participation in the Plan because the information may be out of date at the time your Performance Units vest or your Performance Units are settled under the Plan. In addition, the information is general in nature and may not apply to your particular situation, and the Company is not in a position to assure you of any particular result. Accordingly, you should seek appropriate professional advice as to how the relevant laws in your country may apply to your situation. If you are a citizen or resident of a country other than the country in which you are working or if you transfer employment after the Performance Units are granted to you, the information contained in this Exhibit B for the country you work in at the time of grant may not be applicable to you and the Company, in its discretion, may determine to what extent the terms and conditions contained herein shall be applicable to you. If you transfer residency and/or employment to another country or are considered a resident of another country listed in this Exhibit B after the Performance Units are granted to you, the terms and/or information contained for that new country (rather than the original grant country) may be applicable to you.

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT B) B-2 AUSTRALIA AMENDED AND RESTATED KBR, INC. 2006 STOCK AND INCENTIVE PLAN Offer Document.

The offer of Performance Units under the Plan to Australian resident employees is intended to comply with the provisions of the Australian Corporations Act 2001 (Cth) (“Corporations Act”), Australian Securities and Investments Commission (“ASIC”) Regulatory Guide 49 and ASIC Class Order 14/1000. Additional Documents. In addition to the information set out in the Agreement, including this Exhibit B, you are also being provided with copies of the following documents: (a) the Plan; and (b) the Plan prospectus. (collectively, the “Additional Documents”). The Additional Documents provide further information to help you make an informed investment decision about participating in the Plan.

The information herein is general information only. It is not advice or information that takes into account your objectives and financial situation. You should consider obtaining your own financial product advice from a person who is licensed by ASIC to give such advice. Risk Factors for Australian Residents. You should have regard to risk factors relevant to investment in securities generally and, in particular, to the holding of shares of Stock. For example, the price at which a share of Stock is quoted on the New York Stock Exchange (“NYSE”) may increase or decrease due to a number of factors. There is no guarantee that the price of a share of Stock will increase. Factors which may affect the price of a share of Stock include fluctuations in the domestic and international market for the listed stocks, general economic conditions, including interest rates, inflation rates, legislation or regulation, the nature of the markets in which the Company operates and general operational and business risks.

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT B) B-3 More information about potential factors that could affect the Company’s business and financial results is included in the Company’s most recent Annual Report on Form 10-K and other filings the Company may make from time to time with the U.S. Securities and Exchange Commission. Copies of these reports are available at xxxx://xxx.xxx and upon request to the Company. In addition, you should be aware that the Australian dollar value of the shares of Stock you may acquire under the Plan will be affected by the U.S./Australian dollar exchange rate. Participating in the Plan involves risks related to fluctuations in this rate of exchange. Common Stock in a U.S. Corporation. Common stock of a U.S. corporation is analogous to ordinary shares of an Australian corporation. Each holder of a share of Stock is entitled to one vote. Further, shares of Stock are not liable to any further calls for payment of capital or for other assessment by the Company and have no sinking fund provisions, pre-emptive rights, conversion rights or redemption provisions. Ascertaining the Market Price of Shares. You may ascertain the market price of a share of Stock by obtaining the current trading price of a share on the NYSE at xxxxx://xxx.xxxx.xxx/xxxxx under the ticker “KBR”. The Australian dollar equivalent of that price can be obtained at: xxxx://xxx.xxx.xxx.xx/xxxxxxxxxx/xxxxxxxxx/xxxxxxxx- rates.html. This will not be a prediction of the market price of an individual share when such shares are acquired under the Plan or of the applicable exchange rate on the acquisition date. Tax Information. The Plan is a plan to which subdivision 83A-C of the Income Tax Assessment Act 1997 (Cth) applies (subject to conditions in the Act). Exchange Control Information. Exchange control reporting is required for cash transactions exceeding AUD10,000 and for international fund transfers. The Australian bank assisting with the transaction will file the report for you.

Any Stock issued upon settlement of the Performance Units will be deposited into a Company-designated brokerage account outside Bahrain. In no event will Stock be issued or delivered in Bahrain. The issuance of Stock pursuant to the Performance Units described herein has not and will not be registered in Bahrain and, hence, the Stock described herein may not be admitted or used for offering, placement or public circulation in Bahrain.

US/INTERNATIONAL EMPLOYEE (CASH/STOCK) (EXHIBIT B) B-6 CANADA AMENDED AND RESTATED KBR, INC. 2006 STOCK AND INCENTIVE PLAN Foreign Account/Asset Tax Reporting Information. You may be required to report your specified foreign property on Form T1135 (Foreign Income Verification Statement) if the total cost of your specified foreign property exceeds C$100,000 at any time in the year. Foreign specified property includes cash, any shares of Stock issued to you upon vesting and settlement of your Award as well as the Performance Units. Performance Units must be reported - generally at a nil cost - if the C$100,000 cost threshold is exceeded because of other foreign property that you hold. If shares of Stock are acquired, their cost generally is the adjusted cost base (“ACB”). The ACB would normally equal the fair market value of the shares of Stock issued to you upon vesting and settlement of your Award, but if you own other shares, this ACB may have to be averaged with the ACB of the other shares. The Form T1135 is required for every year during which your foreign specified property exceeds C$100,000 and must be filed with your annual tax return. Termination of Employment. The following provision supplements Paragraph 8(j) of the Agreement and supplements the balance of the Agreement: For purposes of this Award, in the event of your termination of employment for any reason (regardless of the reason for such termination and whether or not the termination is later found to be invalid, unlawful or in breach of employment laws in the jurisdiction where you are providing services or the terms of your employment agreement, if any), unless otherwise provided in this Agreement or the Plan, your right to vest in the Performance Units, if any, will terminate effective as of the date that is the earliest of (1) the date you are no longer actually providing services to the Company or any of its Subsidiaries; or (2) the date you receive (or provide) written notice of termination of employment. Subject to the below, on and after such date, you will no longer be considered to be an "employee" or "employed" for the purposes of this Agreement. Unless explicitly required by applicable legislation, such date will exclude and will not be extended by any period during which notice, pay in lieu of notice or related payments or damages are provided or required to be provided under statute, contract, common/civil law or otherwise. Furthermore, you will not earn, or be entitled to earn, any pro-rated vesting for that portion of time before the date on which your right to vest terminates, nor will you be entitled to any compensation for lost vesting. Notwithstanding the foregoing, if applicable employment standards legislation explicitly requires continued entitlement to vesting during a statutory notice period, your right to vest in the Performance Units, if any, will terminate effective as of the last day of your minimum statutory notice period, but you will not earn or be entitled to pro-rated vesting if the vesting date falls after the end of your statutory notice period, nor will you be entitled to any compensation for lost vesting.
