PERFORMANCE STOCK UNIT AGREEMENT

AGREEMENT by and between KBR, Inc., a Delaware corporation (the “Company”), and ________________ (“Employee”) made effective as of ____________________ (the “Grant Date”).

1.    Grant of Performance Stock Units.

(a)    Units. Pursuant to the KBR, Inc. 2006 Stock and Incentive Plan, as amended and restated (the “Plan”), units evidencing the right to receive __________ shares of the Company’s common stock (“Stock”), are awarded to Employee, subject to the conditions of the Plan and this Agreement (the “Performance Stock Units”).

(b)    Plan Incorporated. Employee acknowledges receipt of a copy of the Plan, and agrees that this award of Performance Stock Units shall be subject to all of the terms and conditions set forth in the Plan, including future amendments thereto, if any, pursuant to the terms thereof, which is incorporated herein by reference as a part of this Agreement. Except as defined herein, capitalized terms shall have the same meanings ascribed to them under the Plan.

2.    Terms of Performance Stock Units. Employee hereby accepts the Performance Stock Units and agrees with respect thereto as follows:

(a)    Forfeiture of Performance Stock Units. In the event of termination of Employee’s employment with the Company or any employing Subsidiary of the Company for any reason other than (i) normal retirement on or after age 70, (ii) death or (iii) disability (disability being defined as being physically or mentally incapable of performing either the Employee’s usual duties as an Employee or any other duties as an Employee that the Company or employing Subsidiary reasonably makes available and such condition is likely to remain continuously and permanently, as determined by the Company or employing Subsidiary), or except as otherwise provided in the second and third sentences of subparagraph (c) of this Paragraph 2, Employee shall, for no consideration, forfeit all Performance Stock Units to the extent they are not fully vested. Notwithstanding the foregoing, if the Company determines that there has been a legal judgment and/or legal development in Employee’s jurisdiction that likely would result in the favorable treatment that applies to the Performance Stock Units under the Plan being deemed unlawful and/or discriminatory, the provision above regarding termination of employment related to normal retirement on or after age 70 shall not be applicable to Employee. In addition, except as otherwise provided in the second and third sentences of subparagraph (c) of this Paragraph 2, Employee shall, for no consideration, forfeit all of the Performance Stock Units on December 31, 2016, if a consolidated net cost savings target of $175 million (as measured for purposes of the publicly disclosed Company cost savings target) is not achieved and approved by the Committee that administers the Plan (the “Committee”) and the Company’s Chief Executive Officer.

(b)    Assignment of Award. The Performance Stock Units may not be sold, assigned, pledged, exchanged, hypothecated or otherwise transferred, encumbered or disposed of unless transferable by will or the laws of descent and distribution or pursuant to a “qualified domestic relations order” as defined by the U.S. Internal Revenue Code (the “Code”).

(c)    Vesting Schedule. The Performance Stock Units shall vest in accordance with the following schedule provided that Employee has been continuously employed by the Company from the date of this Agreement through the applicable vesting date and such Performance Stock Units have not been forfeited pursuant to the last sentence of subparagraph (a) of this Paragraph 2:

Notwithstanding the foregoing, unless otherwise provided in an Other Agreement pursuant to Paragraph 11, the Performance Stock Units shall become fully vested on the earliest of (i) the occurrence of Employee’s Involuntary Termination or termination for Good Reason within two years following a Corporate Change (as such terms are defined in the Plan), (ii) the date Employee’s employment with the Company is terminated by reason of death or disability (as determined above), or (iii) Employee’s attainment of age 70 while employed with the Company; provided, however, that if the Performance Stock Units have been forfeited pursuant to the last sentence of subparagraph (a) of this Paragraph 2 prior to the date of the occurrence of an event described in clause (i), (ii) or (iii) of this sentence, then the Performance Stock Units shall remain forfeited and shall not vest upon the occurrence of any such event. In the event Employee’s employment is terminated for any other reason, including retirement prior to age 70 with the approval of the Company or employing Subsidiary, the Committee or its delegate, as appropriate, may, in the Committee’s or such delegate’s sole discretion, approve the acceleration of the vesting of any or all Performance Stock Units that have not yet been forfeited and which are still outstanding and subject to restrictions, such vesting acceleration to be effective on the date of such approval or Employee’s termination date, if later. Notwithstanding the foregoing, in no event shall the Performance Stock Units become fully vested prior to the expiration of one month from the Grant Date.

Notwithstanding the foregoing, if the Company determines that there has been a legal judgment and/or legal development in Employee’s jurisdiction that likely would result in the favorable retirement treatment that applies to the Performance Stock Units under the Plan being deemed unlawful and/or discriminatory, Performance Stock Units shall not become fully vested on Employee's attainment of age 70 while still employed by the Company. Instead, Performance Stock Units that have not yet been forfeited and which are still outstanding and subject to restrictions shall become fully vested when Employee's employment is terminated for any reason with at least 25 years of service at the Company or employing Subsidiary (or such lesser number of years of service under special circumstances as may be determined in the Committee’s (or its delegate’s) sole discretion) subject, however, to this being considered nondiscriminatory by legal counsel and to the Committee's (or its delegate’s) sole discretion to approve such acceleration of vesting.

(d)    Stockholder Rights. Employee shall have no rights of a stockholder with respect to shares of Stock subject to this Award unless and until such time as the Award has been settled by the transfer of shares of Stock to Employee.

(e)    Payment for Vested Performance Stock Units. Payment for vested Performance Stock Units shall be made as soon as administratively practicable after vesting, but in no event later than thirty days after the vesting date. Settlement will be made in the form of shares of Stock equal in number to the number of Performance Stock Units with respect to which payment is being made on the applicable date; provided, however, that payment for a vested Performance Stock Unit shall be made at the time provided above solely in cash (in lieu of in the form of a share of Stock) in an amount equal to the Fair Market Value as of the vesting date of such Performance Stock Unit if there are an insufficient number of shares available for delivery under the Plan at the time of such settlement as determined by the Committee or its delegate in the Committee’s or such delegate’s sole discretion. Notwithstanding the foregoing, the Company shall not be obligated to deliver any shares of Stock if counsel to the Company determines that such sale or 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.

(f)    Recovery of Benefits. The Company shall seek recovery of any benefits provided hereunder to Employee 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 Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the regulations thereunder or any other applicable law.

3.    Responsibility for Taxes. Employee acknowledges that, regardless of any action taken by the Company, or if different, Employee’s employer (“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 Employee’s participation in the Plan and legally applicable to Employee (“Tax-Related Items”), is and remains Employee’s responsibility and may exceed the amount actually withheld by the Company and/or the Employer. Employee further acknowledges that the Company and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Performance Stock Units, including but not limited to, the grant, vesting or settlement of the Performance Stock Units, the subsequent sale of Stock acquired pursuant to such settlement and the receipt of any dividends; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Performance Stock Units to reduce or eliminate the Employee’s liability for Tax-Related Items or achieve any particular tax result. Further, if Employee is subject to Tax-Related Items in more than one jurisdiction between the Grant Date and the date of any relevant taxable event, Employee acknowledges that the Company and/or the 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, Employee agrees to pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, Employee authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

(a)    withholding from Employee’s wages or other cash compensation paid to Employee by the Company and/or the Employer; or

(b)    withholding from proceeds of the sale of shares of Stock acquired upon settlement of the Performance Stock Units either through a voluntary sale or through a mandatory sale arranged by the Company (on Employee’s behalf pursuant to this authorization without further consent); or

(c)    withholding in shares of Stock to be issued upon settlement of the Performance Stock Units.

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 Employee will receive a refund of any over-withheld amount in cash and will have no entitlement to the Stock equivalent. If the obligation for Tax-Related Items is satisfied by withholding in Stock, for tax purposes, Employee is deemed to have been issued the full number of shares of Stock subject to the vested Performance Stock Units, notwithstanding that a number of the shares of Stock are held back solely for the purpose of paying the Tax-Related Items.

Employee agrees to pay to the Company or the Employer, including through withholding from Employee's wages or other cash compensation paid to Employee by the Company and/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 Employee’s participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the Stock or the proceeds of the sale of Stock, if Employee fails to comply with Employee’s obligations in connection with the Tax-Related Items.

Notwithstanding the preceding provisions of this Paragraph 3, Employee’s liability with respect to Tax-Related Items shall be subject to any international tax assignment agreement then in effect between Employee and the Company, the Employer or any of their respective affiliates or any tax policies or procedures applicable to the Employee’s home

country, and in the event of any conflict between the terms of this Paragraph 3 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.

4.    Employment Relationship. For purposes of this Agreement, Employee shall be considered to be in the employment of the Company as long as Employee remains an employee of the Company, a Parent Corporation or Subsidiary of the Company, or a corporation or a Parent Corporation or subsidiary of such corporation assuming or substituting a new award for this Award. Without limiting the scope of the preceding sentence, it is expressly provided that Employee 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 Employee. Any question as to whether and when there has been a termination of such employment, and the cause of such termination, shall be determined by the Committee, or its delegate, as appropriate, and its determination shall be final.

5.    Committee’s Powers. No provision contained in this Agreement shall in any way terminate, modify or alter, or be construed or interpreted as terminating, modifying or altering any of the powers, rights or authority vested in the Committee or, to the extent delegated, in its delegate pursuant to the terms of the Plan or resolutions adopted in furtherance of the Plan, including, without limitation, the right to make certain determinations and elections with respect to the Performance Stock Units.

6.    Data Privacy Notice and Consent. Employee hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Employee’s personal data as described in this Agreement and any other Performance Stock Unit grant materials by and among, as applicable, Employee’s employer, the Company, and its Subsidiaries for the exclusive purpose of implementing, administering and managing Employee’s participation in the Plan.

(c)    all decisions with respect to future Performance Stock Units or other grants, if any, will be at the sole discretion of the Company;

(d)    the grant of Performance Stock Units and Employee’s participation in the Plan will not create a right to employment or be interpreted as forming an employment or service contract with the Company, the Employer or any Subsidiary of the Company and shall not interfere with the ability of the Company, the Employer or any Subsidiary of the Company, as applicable to terminate Employee’s employment or service relationship (if any);

(e)    Employee’s participation in the Plan is voluntary;

(f)    the Performance Stock Units and the Stock underlying the Performance Stock Units are not intended to replace any pension rights or compensation;

(i)    no claim or entitlement to compensation or damages shall arise from forfeiture of Performance Stock Units resulting from Employee ceasing to provide employment or other services to the Company or the Employer (for any reason whatsoever, and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Employee is employed or the terms of Employee's employment agreement, if any) and in consideration of the grant of Performance Stock Units to which Employee is not otherwise entitled, Employee irrevocably agrees never to institute any claim against the Company, any of its Subsidiaries or the Employer;

(k)    unless otherwise provided in the Plan or by the Company in its discretion, the Performance Stock Units and the benefits evidenced by this Agreement do not create any entitlement to have the Performance Stock 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; and

(l)    the following provisions apply only if Employee is providing services outside the United States: (i) the Performance Stock Units and the shares of Stock subject to the Performance Stock Units are not part of normal or expected compensation or salary for any purpose; and (ii) Employee acknowledges and agrees that neither the Company, the Employer nor any Subsidiary of the Company shall be liable for any foreign exchange rate fluctuation between Employee's local currency and the United States Dollar that may affect the value of the Performance Stock Units or of any amounts due to Employee pursuant to the settlement of the Performance Stock Units or the subsequent sale of any shares of Stock acquired upon settlement.

EMPLOYEE:

Date:    

This Addendum includes special country-specific terms that apply to residents in countries listed below. This Addendum 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 Addendum also includes information regarding exchange controls and certain other issues of which Employee should be aware with respect to Employee’s participation in the Plan. The information is based on the securities, exchange control and other laws in effect in the respective countries as of February 2014. Such laws are often complex, change frequently, certain individual exchange control reporting requirements may apply upon vesting of Performance Stock Units and/or sale of Stock and results may be different based on the particular facts and circumstances. As a result, the Company strongly recommends that Employee does not rely on the information noted herein as the only source of information relating to the consequences of Employee’s participation in the Plan because the information may be out of date at the time Employee’s Performance Stock Units vest or Employee sells shares of Stock acquired under the Plan.

In addition, the information is general in nature and may not apply to Employee’s particular situation, and the Company is not in a position to assure Employee of any particular result. Accordingly, Employee is advised to seek appropriate professional advice as to how the relevant laws in Employee’s country may apply to Employee’s situation.

If Employee is a citizen or resident of a country other than the country in which Employee is working, or if Employee transfers employment after the Performance Stock Units are granted to Employee, the information contained in this Addendum for the country Employee works in at the time of grant may not be applicable to Employee and the Company, in its discretion, determines to what extent the terms and conditions contained herein shall be applicable to Employee. If Employee transfers residency and/or employment to another country or is considered a resident of another country listed in the Addendum after the Performance Stock Units are granted to Employee, the terms and/or information contained for that new country (rather than the original grant country) may be applicable to Employee.

Due to exchange control regulations in Algeria, Employee, or in the event of Employee’s death, the Employee’s legal representative, shall receive only a cash payment in an amount equal to the value of the shares of Stock on each vesting date, as provided in Paragraph 2(c) of the Agreement. Any provisions in the Agreement referring to the issuance of shares of Stock pursuant to vested Performance Stock Units shall not be applicable to Employee so long as Employee is a resident of Algeria. So long as the Employee is a resident of Algeria, Employee may not receive or hold shares of Stock in connection with the Performance Stock Units awarded under the Plan.

Employee acknowledges that, even though Employee receives only a cash payment upon vesting of the Performance Stock Units, he or she may still be subject to certain exchange control requirements under local laws. The cash payment and the receipt of any dividends must be repatriated to Algeria. Employee is advised to consult with his or her personal consultant to ensure compliance with any exchange control obligations arising from Employee’s participation in the Plan.

Employee may need to obtain prior approval from the Angolan central bank prior to opening a non-Angolan bank or brokerage account and receiving shares of Stock or proceeds from the sale of shares of Stock into such account. Proceeds from the sale of shares of Stock and the receipt of any dividends must be repatriated to Angola. Employee is advised to consult with his or her personal consultant to ensure compliance with any exchange control obligations arising from Employee’s participation in the Plan.

Employee’s right to participate in the Plan and receive Performance Stock Units granted under the Plan are subject to an Australian Addendum to the Plan. Employee’s right to receive Performance Stock Units is subject to the terms and conditions as stated in the Australian Addendum, the specific relief instrument granted by the Australian Securities and Investment Commission, the Plan and the Agreement.

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 Employee. If there is no Australian bank involved in the transfer, Employee will have to file the report.

If Employee acquires shares of Stock under the Plan and offers the shares of Stock for sale to a person or entity resident in Australia, the offer may be subject to disclosure requirements under Australian law. Employee should obtain legal advice on disclosure obligations prior to making any such offer.

By accepting the Performance Stock Units, Employee agrees that he or she will comply with Brazilian law when he or she vests in the Performance Stock Units and sells shares of Stock. Employee also agrees to report any and all taxes associated with the vesting of the Performance Stock Units, the sale of shares of Stock acquired pursuant to the Plan and the receipt of any dividends.

Employee must prepare and submit a declaration of assets and rights held outside Brazil to the Central Bank on an annual basis if he or she holds assets or rights valued at more than US$100,000. The assets and rights that must be reported include shares of Stock.

Notwithstanding any discretion in the Plan or anything to the contrary in the Agreement, the award of Performance Stock Units does not provide any right for Employee to receive a cash payment and shall be paid in shares of Stock only.

Employee may be required to report his or her foreign property on Form T1135 (Foreign Income Verification Statement) if the total cost of his or her foreign property exceeds C$100,000 at any time in the year. Foreign property includes shares of Stock acquired under the Plan.

The following provision supplements Paragraph 2 of the Agreement:

In the event of Employee’s termination of employment for any reason (whether or not in breach of local labor laws), unless otherwise provided in this Agreement or the Plan, Employee’s right to vest in the Performance Stock Units, if any, will terminate effective as of the date that is the earlier of (1) the date upon which Employee’s employment with the Company or any of its Subsidiaries is terminated; (2) the date Employee is no longer actively providing services to the Company or any of its Subsidiaries; or (3) the date Employee receives written notice of termination of employment from the Employer, regardless of any notice period or period of pay in lieu of such notice required under applicable laws (including, but not limited to statutory law, regulatory law and/or common law); the Company shall have the exclusive discretion to determine when the Employee is no longer actively employed for purposes of the Performance Stock Units (including whether Employee may be considered to be providing services while on a leave of absence).

This provision supplements Paragraph 6 of the Agreement:

Employee hereby authorizes the Company and representatives of any Subsidiary to discuss with and obtain all relevant information from all personnel, professional or not, involved in the administration and operation of the Plan. Employee further authorizes the Company and any Subsidiary and the administrators of the Plan to disclose and discuss the Plan with their advisors. Employee further authorizes the Company and any Subsidiary to record such information and to keep such information in Employee’s file.

The parties acknowledge that it is their express wish that the Agreement, including this Addendum, as well as all documents, notices and legal proceedings entered into, given or instituted pursuant hereto or relating directly or indirectly hereto, be drawn up in English.

Due to local regulatory requirements, upon vesting of the Performance Stock Units, Employee agrees to the immediate sale of any shares of Stock to be issued to him or her upon vesting and settlement of the Performance Stock Units. Employee further agrees that the Company is authorized to instruct its designated broker to assist with the mandatory sale of such shares of Stock (on Employee’s behalf pursuant to this authorization) and Employee expressly authorizes the Company’s designated broker to complete the sale of such shares of Stock. Employee acknowledges that the Company’s designated broker is under no obligation to arrange for the sale of shares of Stock at any particular price. Upon sale of shares of Stock, the Company agrees to pay Employee the cash proceeds from the sale of shares of Stock, less any brokerage fees or commissions and subject to any obligation to satisfy the Tax-Related Items.

Employee understands and agrees that, to facilitate compliance with exchange control requirements, Employee will be required to immediately repatriate to China the cash proceeds from the immediate sale of shares of Stock issued upon the vesting of the Performance Stock Units. Employee further understands that, under local law, such repatriation of the cash proceeds may need to be effectuated through a special exchange control account established by the Company or its Subsidiaries, and Employee hereby consents and agrees that the proceeds from the sale of shares of Stock acquired under the Plan may be transferred to such special account prior to being delivered to Employee. The Company may deliver the proceeds to Employee in U.S. dollars or local currency at the Company’s discretion. If the proceeds are paid in U.S. dollars, Employee understands that he or she will be required to set up a U.S. dollar bank account in China so that the proceeds may be deposited into this account. If the proceeds are converted to local currency, there may be delays in delivering the proceeds to Employee and due to fluctuations in the Stock trading price and/or the U.S. dollar/PRC exchange rate between the vesting/sale date and (if later) when the sale proceeds can be converted into local currency, the sale proceeds that Employee receives may be more or less than the market value of the shares of Stock on the vesting/sale date (which is the amount relevant to determining Employee’s tax liability). Employee agrees to bear the risk of any currency fluctuation between the date the Performance Stock Units vest and the date of conversion of the proceeds into local currency.

Employee further agrees to comply with any other requirements that may be imposed by the Company in the future to facilitate compliance with exchange control requirements in China.

Employee must repatriate the proceeds from the sale of shares of Stock and any dividends received in relation to the shares of Stock and convert the proceeds into local currency within a reasonable timeframe (i.e., within 90 days of receipt). Employee will receive a foreign inward remittance certificate (“FIRC”) from the bank where Employee deposits the foreign currency. Employee should maintain the FIRC received from the bank as evidence of the repatriation of the funds in the event that the Reserve Bank of India or the Employer requests proof of repatriation. It is Employee’s responsibility to comply with applicable exchange control laws in India.

Employee is required to declare in his or her annual tax return (a) any foreign assets held by him or her or (b) any foreign bank accounts for which he or she has signing authority.

If Employee remits funds into or out of Indonesia, the Indonesian Bank through which the transaction is made will submit a report on the transaction to the Bank of Indonesia for statistical reporting purposes. For transactions of US$10,000 or more, a description of the transaction must be included in the report. Although the bank through which the transaction is made is required to make the report, Employee must complete a “Transfer Report Form.” The Transfer Report Form will be provided to Employee by the bank through with the transaction is to be made.

This section replaces Paragraph 6 of the Agreement.

Employee understands that the Employer, the Company and any Subsidiary may hold certain personal information about Employee, including, but not limited to, Employee’s name, home address and telephone number, date of birth, social insurance (to the extent permitted under Italian law) or other identification number, salary, nationality, job title, any shares of Stock or directorships held in the Company or any Subsidiary, details of all Performance Stock Units or other entitlement to shares of Stock granted, awarded, canceled, exercised, vested, unvested or outstanding in Employee’s favor, for the exclusive purpose of implementing, managing and administering the Plan (“Data”).

Employee also understands that providing the Company with Data is necessary for the performance of the Plan and that Employee’s refusal to provide such Data would make it impossible for the Company to perform its contractual obligations and may affect Employee’s ability to participate in the Plan.

In accepting the Performance Stock Units, Employee acknowledges that he or she has received a copy of the Plan and the Agreement and has reviewed the Plan and the Agreement, including this Addendum, in their entirety and fully

understands and accepts all provisions of the Plan and the Agreement, including this Addendum. Employee further acknowledges that he or she has read and specifically and expressly approves the following Paragraphs of the Agreement: Paragraph 2: Terms of the Performance Stock Units; Paragraph 3: Responsibility for Taxes; Paragraph 4: Employment Relationship; Paragraph 7: Nature of Grant; Paragraph 10: Compliance with Law; Paragraph 12: Governing Law and Venue; Paragraph 14: Insider Trading/Market Abuse Laws; Paragraph 15: Electronic Delivery and Acceptance; Paragraph 16: Severability; Paragraph 18: Addendum; Paragraph 19: Imposition of Other Requirements and the Data Privacy Notice in this Addendum.

Starting from tax returns filed in 2014 for fiscal year 2013, if Employee is an Italian resident who, at any time during the fiscal year, holds foreign financial assets (including cash and shares of Stock) which may generate income taxable in Italy, Employee is required to report these assets on his or her annual tax return for the year during which the assets are held, or on a special form if no tax return is due. These reporting obligations also apply if Employee is the beneficial owner of foreign financial assets under Italian money laundering provisions.

As from 2011, Italian residents may be subject to tax on the value of financial assets held outside of Italy. The taxable amount will be the fair market value of the financial assets. The fair market value is considered to be the value of the shares of Stock on the stock market on December 31 of each year or on the last day of holding the shares of Stock (in such case, or when the shares of Stock are acquired during the course of the year, the tax is levied in proportion to the actual days of holding over the calendar year).

If Employee is a resident of Japan or a foreign national who has established permanent residency in Japan, Employee will be required to report details of any assets (including any Stock acquired under the Plan) held outside Japan as of December 31st of each year, to the extent such assets have a total net fair market value exceeding ¥50,000,000. Such report will be due by March 15th of the following year. The penalty for fraudulent reporting is imprisonment up to one year or a fine up to ¥500,000. Employee should consult with his or her personal tax advisor as to whether the reporting obligation applies to him or her and whether he or she will be required to report details of any outstanding Performance Stock Units or shares of Stock held by him or her in the report.

If Employee is a resident of Kazakhstan, he or she will be required to notify the National Bank of Kazakhstan if the value of the shares of Stock upon vesting of the Performance Stock Units exceeds US$100,000. Employee is responsible for complying with applicable exchange control regulations in Kazakhstan. As the exchange control regulations in Kazakhstan may change without notice, Employee should consult a legal advisor to ensure compliance with the regulations.

Exchange control laws require Korean residents who realize US$500,000 or more from the sale of shares of Stock or receipt of dividends in a single transaction are required to repatriate the proceeds to Korea within 18 months of receipt.

Employee will be required to declare all foreign accounts (i.e., non-Korean bank accounts, brokerage accounts, etc.) to the Korean tax authorities and file a report if the monthly balance of such accounts exceeds a certain limit (currently KRW 1 billion or an equivalent amount in foreign currency).

In accepting the award of Performance Stock Units, Employee acknowledges that Employee has received a copy of the Plan, has reviewed the Plan and the Agreement in their entirety and fully understands and accepts all provisions of the Plan and the Agreement. Employee further acknowledges that Employee has read and specifically and expressly approves the terms and conditions of Paragraph 7 of the Agreement, in which the following is clearly described and established:

In accepting the award of Performance Stock Units, Employee expressly recognizes that KBR, Inc., with registered offices at 601 Jefferson Street, Suite 3400, Houston, Texas 77002, U.S.A., is solely responsible for the administration of the Plan and that Employee’s participation in the Plan and acquisition of shares of Stock does not constitute an employment relationship between Employee and KBR, Inc. since Employee is participating in the Plan on a wholly commercial basis and Employee’s sole employer is KBR in Mexico (“KBR-Mexico”), not KBR, Inc. in the U.S. Based on the foregoing, Employee expressly recognizes that the Plan and the benefits that Employee may derive from participation in the Plan do not establish any rights between Employee and Employee’s employer, KBR-Mexico, and do not form part of the employment conditions and/or benefits provided by KBR-Mexico and any modification of the Plan or its termination shall not constitute a change or impairment of the terms and conditions of Employee’s employment.

Employee further understands that Employee’s participation in the Plan is as a result of a unilateral and discretionary decision of KBR, Inc.; therefore, KBR, Inc. reserves the absolute right to amend and/or discontinue Employee’s participation at any time without any liability to Employee.

Finally, Employee hereby declares that Employee does not reserve to Employee any action or right to bring any claim against KBR, Inc. for any compensation or damages regarding any provision of the Plan or the benefits derived under the Plan, and Employee therefore grants a full and broad release to KBR, Inc., its Subsidiary, branches, representation offices, its shareholders, officers, agents or legal representatives with respect to any claim that may arise.

Aceptando este Premio (Award), el Participante (Employee) reconoce que ha recibido una copia del Plan, que lo ha revisado como así también el Convenio en su totalidad, y comprende y está de acuerdo con todas las disposiciones tanto del Plan como del Convenio. Asimismo, el Participante reconoce que ha leído y específicamente y expresamente manifiesta la conformidad del Participante con los términos y condiciones establecidos en la cláusula 7 de dicho Convenio, en el cual se establece claramente que:

There are no country specific provisions.

The sale or disposal of shares of Stock acquired under the Plan may be subject to certain restrictions under Philippine securities laws. Those restrictions should not apply if the offer and resale of the shares of Stock takes place outside of the Philippines through the facilities of a stock exchange on which the shares of Stock are listed. The shares of Stock currently are listed on the New York Stock Exchange in the United States of America.

There are no country specific provisions.

Any shares of Stock issued pursuant to the Performance Stock Units shall be delivered to Employee through a brokerage account in the U.S. Employee may hold shares of Stock in Employee’s brokerage account in the U.S.; however, in no event will shares of Stock issued to Employee and/or share certificates or other instruments be delivered to Employee in Russia. Employee is not permitted to make any public advertising or announcements regarding the Performance Stock Units in Russia, or promote these to other Russian legal entities or individuals, and Employee is not permitted to sell or otherwise dispose of shares of Stock directly to other Russian legal entities or individuals. Employee is permitted to sell shares of Stock only on the New York Stock Exchange and only through a U.S. broker.

Within a reasonably short time after the sale of shares of Stock, the cash proceeds must be initially credited to Employee through a foreign currency account at an authorized bank in Russia. After the cash proceeds are initially received in Russia, they may be further remitted to foreign banks subject to the following limitations: (i) the foreign account may be opened only for individuals; (ii) the foreign account may not be used for business activities; and (iii) the Russian tax authorities must be given notice about the opening/closing of each foreign account within one month of the account opening/closing. Employee is encouraged to contact his or her personal advisor before remitting proceeds from participation in the Plan to Russia, as exchange control requirements may change.

Employee acknowledges that the Agreement, the grant of the Performance Stock Units, the Plan and all other materials Employee may receive regarding participation in the Plan do not constitute advertising or an offering of securities in Russia. Absent any requirement under local law, the issuance of securities pursuant to the Plan has not and will not be registered in Russia and therefore, the securities described in any Plan-related documents may not be used for offering or public circulation in Russia.

If Employee continues to hold shares of Stock acquired at vesting of the Performance Stock Units after an involuntary termination of employment, Employee will not be eligible to receive unemployment benefits in Russia.

The following provisions supplement Paragraph 6: Data Privacy Notice and Consent provision in the Agreement and to the extent inconsistent, the below language for Russia supersedes Paragraph 6: Data Privacy Notice and Consent:

Employee understands and agrees that the Company may require Employee to complete and return a Consent to Processing of Personal Data form (the “Consent”) to the Company. If a Consent is required by the Company but Employee fails to provide such Consent to the Company, Employee understands and agrees that the Company will not be able to administer or maintain the Option or any other awards. Therefore, Employee understands that refusing to complete any required Consent or withdrawing his or her consent may affect Employee’s ability to participate in the Plan. For more information on any required Consent or withdrawal of consent, Employee understands he or she may contact the U.S. human resources representative/U.S. stock administration.

This document may not be distributed in the Kingdom of Saudi Arabia except to such persons as are permitted under the Offers of Securities Regulations issued by the Capital Market Authority.

The Capital Market Authority does not make any representation as to the accuracy or completeness of this document, and expressly disclaims any liability whatsoever for any loss arising from, or incurred in reliance upon, any part of this document. Prospective purchasers of securities offered hereby should conduct their own due diligence on the accuracy of the information relating to the securities. If Employee does not understand the contents of this document, Employee should consult his or her own advisor or an authorized financial advisor.

Notwithstanding any discretion in the Plan or anything to the contrary in the Agreement, the Performance Stock Units do not provide any right for Employee to receive a cash payment and shall be paid in shares of Stock only.

The grant of Performance Stock Units is being made in reliance of section 273(1)(f) of the Securities and Futures Act (Chap. 289) (“SFA”) for which it is exempt from the prospectus and registration requirements under the SFA and is not made to Employee with a view of the Performance Stock Units being subsequently offered to any other party. The Plan has not been lodged or registered as a prospectus with the Monetary Authority of Singapore. Employee should note that the Restricted Share Units are subject to section 257 of the SFA and Employee will not be able to make (i) any subsequent sale of the shares of Stock in Singapore or (ii) any offer of such subsequent sale of the shares of Stock subject to the Restricted Share Units in Singapore, unless such sale or offer in is made pursuant to the exemptions under Part XIII Division (1) Subdivision (4) (other than section 280) of the SFA.

If Employee is a director of a Singapore Subsidiary, Employee must notify the Singapore Subsidiary in writing within two business days of Employee receiving or disposing of an interest (e.g., Performance Stock Units, shares of Stock) in the Company or any Subsidiary or within two business days of Employee becoming a director if such an interest exists at the time. This notification requirement also applies to an associate director of the Singapore Subsidiary and to a shadow director of the Singapore Subsidiary (i.e., an individual who is not on the board of directors of the Singapore Subsidiary but who has sufficient control so that the board of directors of the Singapore Subsidiary acts in accordance with the “directions and instructions” of the individual).

By Employee’s acceptance of the Performance Stock Units and the Agreement, Employee agrees to notify his or her Employer of the amount of Employee’s gain at vesting. Once the notification is made, Employee’s Employer will obtain a directive from the South African Revenue Service as to the correct amount of tax to be withheld. If Employee fails to advise Employee’s employer of any gain Employee receives, Employee may be liable for a fine. Employee will be responsible for paying any difference between the actual tax liability and the amount withheld.

Employee is solely responsible for complying with applicable South African exchange control regulations. Because the exchange control regulations change frequently and without notice, Employee should consult Employee’s legal advisor prior to the acquisition or sale of shares of Stock under the Plan to ensure compliance with current regulations. It is Employee’s responsibility to comply with South African exchange control laws, and neither the Company nor the Employer will be liable for any fines or penalties resulting from failure to comply with applicable laws.

There are no country specific provisions.

If proceeds from the sale of shares of Stock or the receipt of dividends are equal to or greater than US$50,000 or more in a single transaction, Employee must repatriate the proceeds to Thailand immediately upon receipt and convert the funds to Thai Baht or deposit the proceeds in a foreign currency deposit account maintained by a bank in Thailand within 360 days of repatriation. In addition, Employee must report the inward remittance to the Bank of Thailand on a foreign exchange transaction form. If Employee fails to comply with these obligations, he or she may be subject to penalties assessed by the Bank of Thailand. Because exchange control regulations change frequently and without notice, Employee should consult his or her personal advisor before selling shares of Stock to ensure compliance with current regulations. Employee is responsible for ensuring compliance with all exchange control laws in Thailand and neither the Company nor any of its Subsidiaries will be liable for any fines or penalties resulting from his or her failure to comply with applicable laws.

The Plan is only being offered to qualified Employees and is in the nature of providing equity incentives to employees of the Company’s affiliate in the United Arab Emirates (“UAE”). Any documents related to the Plan, including the Plan, Plan prospectus and other grant documents (“Plan Documents”), are intended for distribution only to such Employees and must not be delivered to, or relied on by, any other person. Prospective stockholders should conduct their own due diligence on the securities. If Employee does not understand the contents of the Plan Documents, Employee should consult an authorized financial adviser.

The Emirates Securities and Commodities Authority has no responsibility for reviewing or verifying any Plan Documents nor taken steps to verify the information set out in them, and thus, are not responsible for such documents.

The section supplements Paragraph 3 of the Agreement.

Notwithstanding Paragraph 3 of the Agreement, Employee agrees that if he or she do not pay or the Employer or the Company does not withhold from Employee the full amount of Tax-Related Items that Employee owes due to the vesting of the Performance Stock Units, or the release or assignment of the Performance Stock Units for consideration, or the receipt of any other benefit in connection with the Performance Stock Units (the “Taxable Event”) within 90 days after the Taxable Event, or such other period specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) Act 2003, then the amount of income tax that should have been withheld shall constitute a loan owed by Employee to the Employer, effective 90 days after the Taxable Event. Employee agrees that the loan will bear interest at Her Majesty’s Revenue & Customs (“HMRC”) official rate and will be immediately due and repayable by Employee, and the Company and/or the Employer may recover it at any time thereafter by withholding the funds from salary, bonus or any other funds due to Employee by the Employer, by withholding in shares of Stock issued upon vesting and settlement of the Performance Stock Units or from the cash proceeds from the sale of shares of Stock or by demanding cash or a cheque from Employee. Employee also authorizes the Company to delay the issuance of any shares of Stock to Employee unless and until the loan is repaid in full.

Notwithstanding the foregoing, if Employee is an officer or executive director (as within the meaning of Section 13(k) of the U.S. Securities and Exchange Act of 1934, as amended), the terms of the immediately foregoing provision will not apply. In the event that Employee is an officer or executive director and the amount necessary to satisfy Tax-Related Items is not collected from or paid by Employee within 90 days of the Taxable Event, any uncollected amounts of income tax may constitute a benefit to Employee on which additional income tax and national insurance contributions may be payable. Employee acknowledges that Employee ultimately will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Company or the Employer (as appropriate) for the value of any national insurance contributions due on this additional benefit. Employee acknowledges that the Company or the Employer may recover any such additional income tax and national insurance contributions at any time thereafter by any of the means referred to in Paragraph 3 of the Agreement.
