(A) The Compensation Committee shall appoint a Committee to administer, construe and interpret the Plan.

Decisions of the Committee, with respect to any matter involving the Plan, shall be final and binding on the Company, its shareholders, each Employer and all officers and other executives of the Employers. For purposes of ERISA, the Committee shall be the Plan “administrator” and shall be the “named fiduciary” with respect to the general administration of the Plan.

(B) The Committee shall maintain complete and adequate records pertaining to the Plan, including but not limited to Participants’ Accounts, amounts transferred to the Trust, reports from the Trustee and all other records which shall be necessary or desirable in the proper administration of the Plan. The Committee shall furnish the Trustee such information as is required to be furnished by the Committee or the Company pursuant to the Trust Agreement.

(C) The Company shall indemnify and hold harmless each member of the Committee against any and all expenses and liabilities arising out of his or her administrative functions or fiduciary responsibilities, including any expenses and liabilities that are caused by or result from an act or omission constituting the negligence of such member in the performance of such functions or responsibilities, but excluding expenses and liabilities that are caused by or result from such member’s own gross negligence or willful misconduct. Expenses against which such member shall be indemnified hereunder shall include, without limitation, the amounts of any settlement or judgment, costs, counsel fees, and related charges reasonably incurred in connection with a claim asserted or a proceeding brought or settlement thereof.

(D) The Committee may designate any Subsidiary as an Employer by written instrument delivered to the Secretary of the Company and the designated Employer. Such written instrument shall specify the effective date of such designated participation, may incorporate specific provisions relating to the operation of the Plan which apply to the designated Employer only and shall become, as to such designated Employer and its employees, a part of the Plan. Each designated Employer shall be conclusively presumed to have consented to its designation and to have agreed to be bound by the terms of the Plan and any and all amendments thereto upon its submission of information to the Committee required by the terms of or with respect to the Plan; provided, however, that the terms of the Plan may be modified so as to increase the obligations of an Employer only with the consent of such Employer, which consent shall be conclusively presumed to have been given by such Employer upon its submission of any

information to the Committee required by the terms of or with respect to the Plan. Except as modified by the Committee in its written instrument, the provisions of this Plan shall be applicable with respect to each Employer separately, and amounts payable hereunder shall be paid by the Employer which employs the particular Participant, if not paid from the Trust Fund.

(E) No member of the Committee shall have any right to vote or decide upon any matter relating solely to himself or herself under the Plan or to vote in any case in which his or her individual right to claim any benefit under the Plan is particularly involved. In any case in which a Committee member is so disqualified to act and the remaining members cannot agree, the Compensation Committee shall appoint a temporary substitute member to exercise all the powers of the disqualified member concerning the matter in which he or she is disqualified.

(A) Each Allocation Year the Compensation Committee shall, in its sole discretion, determine what amounts shall be available for allocation to the Accounts of the Participants pursuant to Paragraph (D) below.

(B) No award shall be made to any person while he or she is a voting member of the Compensation Committee.

(C) The Compensation Committee from time to time may adopt, amend or revoke such regulations and rules as it may deem advisable for its own purposes to guide in determining which of the Senior Executives it shall deem to be Participants for a particular Allocation Year and the method and manner of payment thereof to the Participants.

(D) The Compensation Committee, during the Allocation Year involved or during the next succeeding Allocation Year, shall determine which Senior Executives it shall designate as Participants for such Allocation Year and the amounts allocated to each Participant for such Allocation Year. In making its determination, the Compensation Committee shall consider such factors as the Compensation Committee may in its sole discretion deem material. The Compensation Committee, in its sole discretion, may notify a Senior Executive at any time during a particular Allocation Year or in the Allocation Year following the Allocation Year for which the award is made that he or she has been selected as a Participant for all or part of such Allocation Year, and may determine and notify him or her of the amount which shall be allocated to such Participant for such Allocation Year. The decision of the Compensation Committee in selecting a Senior Executive to be a Participant or in making any allocation to him or her shall be final and conclusive, and nothing herein shall be deemed to give any Senior Executive or his or her legal representatives or assigns any right to be a Participant for such Allocation Year or to be allocated any amount except to the extent of the amount, if any, allocated to a Participant for a particular Allocation Year, but at all times subject to the provisions of the Plan.

(E) A Senior Executive whose service is terminated during the Allocation Year may be selected as a Participant for such part of the Allocation Year prior to his or her Termination of Service and be granted such award with respect to his or her services during such part of the Allocation Year as the Compensation Committee, in its sole discretion and under any rules it may promulgate, may determine.

(F) Allocations to Participants under the Plan shall be made by crediting their respective Accounts on the books of their Employers as of the last day of the Allocation Year. Accounts of Participants shall also be credited with interest as of the last day of each Allocation Year, at the rate set forth in Paragraph (G) below, on the average monthly credit balance of the Account being calculated by using the balance of each Account on the first day of each month. Prior to Termination of Service, the annual interest shall accumulate as a part of the Account balance. After Termination of Service, the annual interest for such Allocation Year may be paid as more particularly set forth hereinafter in Article VII, Paragraph (C).

(G) For amounts allocated to a Participant’s Account that are attributable to Allocation Years prior to the 2007 Allocation Year, interest shall be credited on such amounts at the rate of 5% per annum for periods prior to Termination of Service and at the rate of 10% per annum for periods subsequent to Termination of Service. With respect to amounts allocated to a Participant’s Account that are attributable to the 2007 Allocation Year and any subsequent Allocation Years, earnings (or losses) shall be credited (or deducted) based on the moderate premixed portfolio in the KBR Employee Benefit Master Trust (“Master Trust”), or, if no such investment option is offered, on the default investment option under the Master Trust, for periods prior to Termination of Service, and earnings (or losses) shall be credited (or deducted) based on the Vanguard Prime Money Market Fund, or if such Fund is not available, on the Fidelity Money Market Fund, for periods subsequent to Termination of Service.

No Participant shall have any right to commute, encumber, pledge, transfer or otherwise dispose of or alienate any present or future right or expectancy which he or she may have at any time to receive payments of any allocations made to such Participant, all such allocations being expressly hereby made non-assignable and non-transferable; provided, however, that nothing in this Article shall prevent transfer (A) by will, (B) by the applicable laws of descent and distribution or (C) pursuant to an order that satisfies the requirements for a “qualified domestic relations order” as such term is defined in Section 206(d)(3)(B) of the ERISA and Section 414(p)(1)(A) of the Code, including an order that requires distributions to an alternate payee prior to a Participant’s “earliest retirement age” as such term is defined in Section 206(d)(3)(E)(ii) of the ERISA and Section 414(p)(4)(B) of the Code. Attempts to transfer or assign by a Participant (other than in accordance with the preceding sentence) shall, in the sole discretion of the Compensation Committee after consideration of such facts as it deems pertinent, be grounds for terminating any rights of such Participant to any awards allocated to but not previously paid over to such Participant.

All amounts, including interest, credited to a Participant’s Account prior to the 2005 Allocation Year shall be fully vested and not subject to forfeiture for any reason, except as provided in Article V, regardless of the number of years of participation in the Plan by such Participant. All amounts, including interest, credited to a Participant’s Account, which are attributable to the 2005 and 2006 Allocation Years, shall be fully vested and not subject to forfeiture for any reason, except as provided in Article V, when such Participant has five consecutive years of participation in the Plan as measured from the date such Participant first became a Participant in the Plan. All amounts, including interest, credited to a Participant’s Account, which are attributable to the 2007 Allocation Year and any subsequent Allocation Years in which such Participant may receive an award, shall be subject to the graded vesting schedule below such that the portions of the Participant’s Account that become vested over time are not subject to forfeiture for any reason, except as provided in Article V; provided, however, that a minimum of five years (unless the Compensation Committee imposes a different minimum participation requirement for a Senior Executive at the time an award is made) participation in the Plan is required before the Participant’s Account may vest according to the graded vesting schedule below.

Termination Age*	Vesting Percentage
Age 60 or older	100%
59	90%
58	80%
57	70%
56	60%
55	50%
<55	0%

Minimum participation in the Plan of five years (unless the Compensation Committee imposes a different minimum participation requirement for a Senior Executive at the time an award is made).

(A) Upon Termination of Service of a Participant the Committee (i) shall certify to the Trustee or the treasurer of the Employer, as applicable, the amount credited to the Participant’s Account on the books of each Employer for which the Participant was employed at a time when he or she earned an award hereunder, and (ii) shall determine whether the payment of the amount credited to the Participant’s Account under the Plan is to be paid directly by the applicable Employer, from the Trust Fund, if any, or by a combination of such sources (except to the extent the provisions of the Trust Agreement if any, specify payment from the Trust Fund).

(B) Any amounts payable under Paragraph (A) above shall be paid in a single lump sum payment upon Termination of Service. Notwithstanding the foregoing, in the case of a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, any payments payable as a result of the Participant’s Termination of Service (other than death or disability (as defined under Section 409A of the Code)) shall not be payable before the earlier of (i) the date that is six months after the Participant’s Termination of Service, (ii) the date of the Participant’s death, or (iii) the date that otherwise complies with the requirements of Section 409A. For purposes of the Plan, a Participant shall be a “specified employee” for the twelve-month period beginning on April 1 of a Plan Year if the Participant is a “key employee” as defined in Section 416(i) of the Code (without regard to Section 416(i)(5) of the Code) as of December 31 of the preceding Plan Year. The Trustee or the treasurer of the Employer, as applicable, shall make payments of awards in the manner designated, subject to all of the other terms and conditions of this Plan and the Trust Agreement if any. This Plan shall be deemed to authorize the payment of all or any portion of a Participant’s award from the Trust Fund to the extent such payment is required by the provisions of the Trust Agreement, if any.

(C) Any earnings or losses on any payment to be paid to a specified employee under Paragraph (B) above that is delayed because of Section 409(A) shall be adjusted with the final payment. In such case, the interest is accrued on an annual basis, and the “specified employee” will be entitled to the prorated portion of such annual interest, as calculated up until the actual date of payout pursuant to this Paragraph (or, with respect to post 2006 allocations, as adjusted for earnings and losses as provided in IV (G)).

(D) If a Participant shall die prior to Termination of Service while in the service of an Employer, or after Termination of Service and prior to the time when all amounts payable to him or her under the Plan have been paid to such Participant, any remaining amounts payable to the Participant hereunder shall be payable to the estate of the Participant no later than 74 days after the Participant’s death. The Committee shall cause the Trustee or the treasurer of the Employer, as applicable, to pay to the estate of the Participant all of the vested benefits then standing to his or her credit in a lump sum.

(E) If the Plan is terminated pursuant to the provisions of Article X, the Compensation Committee may, at its election and in its sole discretion, cause the Trustee or the treasurer of the Employer, as applicable, to pay to all Participants all of the awards then standing

to their credit in the form of lump sum payments, provided such distribution is in compliance with the requirements of Section 409A.

This Plan constitutes a mere promise by the Employers to make benefit payments in the future and Participants have the status of general unsecured creditors of the Employers. Further, the adoption of this Plan and any setting aside of amounts by the Employers with which to discharge their obligations hereunder shall not be deemed to create a trust; legal and equitable title to any funds so set aside shall remain in the Employers, and any recipient of benefits hereunder shall have no security or other interest in such funds. Any and all funds so set aside shall remain subject to the claims of the general creditors of the Employers, present and future. This provision shall not require the Employers to set aside any funds, but the Employers may set aside such funds if they choose to do so.

Article VIII above to the contrary notwithstanding, the Employers may fund all or part of their obligations hereunder by transferring assets to a domestic trust if the provisions of the trust agreement creating the Trust require the use of the Trust’s assets to satisfy claims of an Employer’s general unsecured creditors in the event of such Employer’s insolvency and provide that no Participant shall at any time have a prior claim to such assets. Any transfers of assets to a trust may be made by each Employer individually or by the Company on behalf of all Employers. The assets of the Trust shall not be deemed to be assets of this Plan.

The Compensation Committee shall have the power and right from time to time to modify, amend, supplement, suspend or terminate the Plan as it applies to each Employer, provided that no such change in the Plan may deprive a Participant of the amounts allocated to his or her Account or be retroactive in effect to the prejudice of any Participant. Any such modification, amendment, supplement suspension or termination shall be in writing and signed by a member of the Compensation Committee.

(A) No Participant shall have any preference over the general creditors of an Employer in the event of such Employer’s insolvency.

(B) Nothing contained herein shall be construed to give any person the right to be retained in the employ of an Employer or to interfere with the right of an Employer to terminate the employment of any person at any time.

(C) If the Committee receives evidence satisfactory to it that any person entitled to receive a payment hereunder is, at the time the benefit is payable, physically, mentally or legally incompetent to receive such payment and to give a valid receipt therefor, and that an individual or institution is then maintaining or has custody of such person and that no guardian, committee or other representative of the estate of such person has been duly appointed, the Committee may direct that such payment thereof be paid to such individual or institution maintaining or having custody of such person, and the receipt of such individual or institution shall be valid and a complete discharge for the payment of such benefit.

(D) Payments to be made hereunder may, at the written request of the Participant, be made to a bank account designated by such Participant, provided that deposits to the credit of such Participant in any bank or trust company shall be deemed payment into his or her hands.

(E) Wherever any words are used herein in the masculine, feminine or neuter gender, they shall be construed as though they were also used in another gender in all cases where they would so apply, and whenever any words are used herein in the singular or plural form, they shall be construed as though they were also used in the other form in all cases where they would so apply.

(F) THIS PLAN SHALL BE CONSTRUED AND ENFORCED UNDER THE LAWS OF THE STATE OF TEXAS EXCEPT TO THE EXTENT PREEMPTED BY FEDERAL LAW.

(G) It is intended that the provisions of this Plan satisfy the requirements of Section 409A and that the Plan be operated in a manner consistent with such requirements to the extent applicable. Therefore, the Committee may make adjustments to the Plan and may construe the provisions of the Plan in accordance with the requirements of Section 409A.

This restatement of the Plan shall be effective from the Effective Date and the Plan shall continue in force during subsequent years unless amended or revoked by action of the Compensation Committee.

Articles XIII, XIV and XV of the Plan are referred to as the “Grandfathered Plan”. The Grandfathered Plan contains the provisions governing the deferrals of accounts earned and vested by Senior Executives on or before December 31, 2004. This Appendix A preserves the material terms of the Grandfathered Plan as in effect on December 31, 2004, and is intended to satisfy the requirements of Section 409A as to grandfathered amounts. The provisions of this Appendix A shall apply to, and be effective only with respect to, the deferral of earned and vested amounts under the Grandfathered Plan before January 1, 2005, and the amounts earned on such deferrals credited at any time. The Plan provides for separate accounting of such amounts deferred, earned, and vested before January 1, 2005, and the Credited Investment Return thereon.

No amendment to the Plan shall be deemed to amend this Appendix A and the relevant provisions of the Plan in effect prior to such amendment unless otherwise specifically set forth therein. Pursuant to Section 1.409A-6(a)(4) of the Treasury Regulations, a modification is material “if a benefit or right existing as of October 3, 2004 is materially enhanced or a new material benefit or right is added, and such material enhancement or addition affects amounts earned and vested before January 1, 2005”.

The provisions of the Plan applicable to the Grandfathered Plan Accounts shall be administered in a manner consistent with the Grandfathered Plan and Appendix A. Wherever the Plan has added, changed, or otherwise altered any terms of the Grandfathered Plan that were in effect on December 31, 2004, in a manner that would constitute a material modification, as described above, such changes will be disregarded in the administration of the Grandfathered Plan Accounts herein.

Interest shall be credited on amounts allocated to Participants’ Accounts at the rate of 5% per annum for periods prior to Termination of Service and at the rate of 10% per annum for periods subsequent to Termination of Service.

All amounts credited to a Participant’s Account shall be fully vested and not subject to forfeiture for any reason except as provided in Article V.

a time when he or she earned an award hereunder, (ii) shall determine whether the payment of the amount credited to the Participant’s Account under the Plan is to be paid directly by the applicable Employer, from the Trust Fund, if any, or by a combination of such sources (except to the extent the provisions of the Trust Agreement if any, specify payment from the Trust Fund) and (iii) shall determine and certify to the Trustee or the treasurer of the Employer, as applicable, the method of payment of the amount credited to a Participant’s Account, selected by the Committee from among the following alternatives:

(1)

single lump sum payment upon Termination of Service;

(2) payment of one-half of the Participant’s balance upon Termination of Service, with payment of the additional one-half to be made on or before the last day of a period of one year following Termination of Service;

(3) monthly installments over a period not to exceed ten years with such payments to commence upon Termination of Service.

The above notwithstanding, if the total amount credited to the Participant’s Account upon Termination of Service is less than $50,000, such amount shall always be paid in a single lump sum payment upon Termination of Service.

(B) Interest on the second half of a payment under Paragraph (A)(2) above shall be paid with the final payment, while interest on payments under Paragraph (A)(3) above may be paid at each year end or may be paid as a part of a level monthly payment computed by the Committee through the use of such methodologies as the Committee shall select from time to time for such purpose.

(C) If a Participant shall die while in the service of an Employer, or after Termination of Service and prior to the time when all amounts payable to him or her under the Plan have been paid to such Participant, any remaining amounts payable to the Participant hereunder shall be payable to the estate of the Participant. The Committee shall cause the Trustee or the treasurer of the Employer, as applicable, to pay to the estate of the Participant all of the awards then standing to his or her credit in a lump sum or in such other form of payment consistent with the alternative methods of payment set forth above as the Committee shall determine after considering such facts and circumstances relating to the Participant and his or her estate as it deems pertinent.

(D) If the Plan is terminated pursuant to the provisions of Article VIII, the Compensation Committee may, at its election and in its sole discretion, cause the Trustee or the treasurer of the Employer, as applicable, to pay to all Participants all of the awards then standing to their credit in the form of lump sum payments.
