KBR Benefit Restoration Plan, as restated effective December 31, 2010

WHEREAS, the Board of Directors of Halliburton Company (“Halliburton”) previously adopted the Halliburton Company Benefit Restoration Plan, as most recently amended and restated effective January 1, 2004, for the benefit of its employees and the employees of its subsidiaries to aid such employees in making more adequate provision for their retirement; and

WHEREAS, Halliburton took action on the Deconsolidation Date to split-off the Company and its subsidiaries such that they ceased to be members of the Halliburton controlled group; and

WHEREAS, the Company desired to provide benefits for certain of its new employees including certain current employees who had previously participated in the HAL Plan, as hereafter defined; and

WHEREAS, pursuant to the terms of the HAL Plan, each Employer thereunder was liable for the benefits related to its employees, and the Company and the Employers hereunder continued to provide to such employees an opportunity to make deferrals of certain amounts, consistent with the provisions of Section 409A of the Internal Revenue Code of 1986 as amended (the “Code”); and

WHEREAS, the provisions of the HAL Plan, as amended through the Effective Date, will remain in effect for all deferrals prior to the Effective Date; and

WHEREAS, the Company desires to preserve the material terms of the HAL Plan as in effect on December 31, 2004 (the “Grandfathered Plan”) in order that the Grandfathered Plan qualify as a grandfathered plan for purposes of Section 409A of the Code; and

WHEREAS, certain provisions applicable solely to the Grandfathered Plan are preserved in Appendix A, for purposes of determining the terms applicable to amounts deferred under the Grandfathered Plan, which provisions shall be substituted for the corresponding provisions contained herein.

WHEREAS, the Company desires to make certain amendments to the Plan effective December 31, 2010, without making any changes to the material terms of the Grandfathered Plan.

NOW THEREFORE, the HAL Plan, including the Grandfathered Plan, is hereby continued for Participants with the terms set forth below, and is hereby renamed the KBR Benefit Restoration Plan to read as follows, effective as of the Effective Date:

The purpose of the KBR Benefit Restoration Plan is to provide a vehicle to restore qualified plan benefits which are reduced as a result of limitations on contributions imposed under the Internal Revenue Code or due to participation in other company sponsored plans and to defer compensation that would otherwise be treated as excessive employee remuneration within the meaning of Section 162(m) of the Internal Revenue Code.

Such Committee, or such successor Committee as may be duly appointed by the Compensation Committee, shall serve at the pleasure of the Compensation Committee. 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.

(ii)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.

(iii)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.

(iv)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 materially 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.

(v)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.

(i)The Committee shall determine for each Allocation Year which Participants' allocations of Employer contributions (other than matching contributions) under qualified defined contribution plans sponsored by the Employers have been reduced for such Allocation Year by reason of the application of Section 401 (a)(17) or Section 415 of the Code, or any combination of such Sections, or by reason of elective deferrals under the KBR Elective Deferral Plan, and shall allocate to the credit of each such Participant under the Plan an amount equal to the amount of such reductions applicable to such Participant. In addition, the Committee shall allocate to the credit of each Participant under the Plan the amount of Employer matching contributions that would have been allocated to such Participant’s account under Employer’s qualified defined contribution plan with respect to (i) the amount of such Participant's compensation (as such term is defined in Employer’s qualified defined contribution plan) deferred under the KBR Elective Deferral Plan for such Allocation Year and (ii) the amount of such compensation not so deferred that is in excess of the compensation limit under Section 401 (a)(17) of the Code for such Allocation Year.

(ii)Allocations to Participants under the Plan shall be made by crediting their respective Account 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 (C) 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 shall be paid as more particularly set forth hereinafter in Article VII, Paragraph (D).

(iii)Interest shall be credited on amounts allocated to Participants' Account at the rate of 10% per annum.

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

(i)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).

(ii)Any amount payable under Paragraph (A) above shall be paid in a single lump sum payment upon Termination of Service. Notwithstanding the foregoing, for purposes of the Plan, all Participants shall be “specified employees” within the meaning of Section 409A(a)(2)(B)(i) of the Code, and 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 Employee’s death, or (iii) the date that otherwise complies with the requirements of Section 409A.

(iii)The Trustee or the treasurer of the Employer, as applicable, shall make payment of awards in the manner required by Paragraph (B) above, 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.

(iv)Interest on any payment to be paid to a specified employee under Paragraph (B) above that is delayed because of Section 409A shall be paid 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.

(v)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 benefits then standing to his or her credit in a lump sum.

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 amendments to the Plan (a) that are required to comply with applicable law or (b) that facilitate Plan administration without increasing benefits under the Plan to any Participants may be made by the Chief Executive Officer of the Company (the “CEO”), or his designee. Notwithstanding the preceding sentence, 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 and the interest rate applicable to amounts credited to Participants’ Accounts for periods subsequent to Termination of Service shall not be reduced below 6% per annum. Any such modification, amendment, supplement, suspension or termination shall be in writing and signed by a member of the Compensation Committee or its designee (or the CEO, or his designee, as applicable).

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

(ii)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.

(iii)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.

(iv)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.

(v)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.

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

(vii)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.

(H)    All deferrals and payments provided for hereunder shall be subject to applicable withholding and other deductions as shall be required of the Employer under any applicable local, state or federal law.

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

Date 31 December 2010    

Articles XIII and XIV 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 Participants 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 interest on the Trust Fund pursuant to Section (B) of Article XIII, below, and credited at any time. The Plan provides for separate accounting of such amounts deferred, earned, and vested before January 1, 2005, and such interest on the Trust Fund.

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 Proposed 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....”

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.

(i)There shall be no further allocations to any Participant under the Grandfathered Plan.

(ii)Interest shall be credited on amounts allocated to Participants' Account at the rate of 10% per annum.

(i)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) 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:

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.

(ii)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.

(iii)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.

(iv)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.
