HESI acknowledges and agrees that, except as may be expressly set forth herein as a Service (including such agreed Additional Services to be provided pursuant to Section 2.3 below) or otherwise expressly set forth in the Separation Agreement, an Ancillary Agreement or other binding definitive agreement, no member of the KBR Group shall be obligated to provide, or cause to be provided, any service or goods to any member of the Halliburton Group.

(c) KBR and members of the KBR Group shall not be required to perform Services hereunder that conflict with or violate any applicable law, contract, license, authorization, certification or permit. KBR will use reasonable best efforts to secure all necessary consents and/or approvals of vendors, lessors and licensors relating to the Services.

SECTION 2.2 Service Coordinators. Each party will nominate in writing a representative to act as the primary contact with respect to the provision of the Services and the resolution of disputes under this Agreement (each such person, a “Service Coordinator”). The initial Service Coordinators shall be the Chief Accounting Officers (or their designated delegates) for each of Halliburton and KBR. Unless HESI and KBR otherwise agree in writing, HESI and KBR agree that all notices and communications relating to this Agreement other than those day to day communications and billings relating to the actual provision of the Services shall be directed to the Service Coordinators in accordance with Section 11.2 hereof. The Service Coordinators shall meet as expeditiously as possible to resolve any dispute hereunder; any dispute that is not resolved by the Service Coordinators within forty-five (45) days shall be resolved in accordance with the dispute resolution and arbitration procedures set forth in Article VII of the Separation Agreement.

SECTION 2.3 Additional Services.

(a) From the date hereof until ninety (90) days following the IPO Closing Date (the “Extension Period”), from time to time HESI may request additional Services from KBR by providing written notice. The cost of such additional Services shall be determined in accordance with the general principles described in Section 3.1(a). Upon the mutual written agreement as to the nature, cost, duration and scope of such additional Services, HESI and KBR shall supplement in writing the Schedules hereto to include such additional Services (such agreed services, the “Additional Services”).

(b) KBR shall be obligated to provide to HESI and the members of the Halliburton Group any Additional Service inadvertently or unintentionally omitted from the list of Initial Services that was provided by the KBR Group to the Halliburton Group immediately prior to the IPO Closing Date or was included in the 2006 budget of Halliburton—KBR intercompany services. KBR, in its sole discretion, may decline to provide any Additional Service requested by HESI which does not meet the criteria of the preceding sentence.

KBR shall have the right to hire third party subcontractors to provide all or part of any Services hereunder so long as such subcontracting is consistent with past practices and the practice applied by KBR generally from time to time within its own organization. If subcontracting for a Service is not consistent with past practices and the practice applied by KBR generally from time to time within its own organization, then KBR shall give notice of its intent to subcontract such Service to HESI and HESI shall have sixty (60) days to determine, in its sole discretion, whether to permit such subcontracting or whether to cancel such Service in accordance with Article VI hereof.

SECTION 2.5 Standard of Performance; Limitation of Liability.

(a) The Services to be provided hereunder shall be performed with the same general degree of care, at the same general level and at the same general degree of accuracy and responsiveness, as when performed within the KBR organization prior to the date of this Agreement. It is understood and agreed that KBR is not a professional provider of the types of services included in the Services and that KBR personnel performing Services have other responsibilities, and will not be dedicated full-time to performing Services.

(b) In the event KBR or any member of the KBR Group fail to provide, or cause to be provided, the Services in accordance herewith, the sole and exclusive remedy of HESI shall be to, at HESI’s sole discretion, within ninety (90) days from the date that KBR fails to provide such Service either (i) have the Service reperformed, or (ii) not pay for such Service, or if payment has already been made, receive a refund of the payment made for such defective service; provided that in the event KBR defaults in the manner described in Section 7.1(ii) or (iii), HESI shall have the further rights set forth in Section 7.1.

(c) EXCEPT AS EXPRESSLY SET FORTH IN THIS SECTION 2.5, NO REPRESENTATIONS OR WARRANTIES OF ANY KIND, IMPLIED OR EXPRESSED, ARE MADE BY KBR OR ANY MEMBER OF THE KBR GROUP WITH RESPECT TO THE SERVICES UNDER THIS AGREEMENT AND ALL SUCH REPRESENTATIONS OR WARRANTIES ARE HEREBY WAIVED AND DISCLAIMED. HESI HEREBY EXPRESSLY WAIVES ANY RIGHT HESI OR ANY MEMBER OF THE HALLIBURTON GROUP MAY OTHERWISE HAVE FOR ANY LOSSES, TO ENFORCE SPECIFIC PERFORMANCE OR TO PURSUE ANY OTHER REMEDY AVAILABLE IN CONTRACT, AT LAW OR IN EQUITY IN THE EVENT OF ANY NON-PERFORMANCE, INADEQUATE PERFORMANCE, FAULTY PERFORMANCE OR OTHER FAILURE OR BREACH BY KBR OR ANY MEMBER OF THE KBR GROUP UNDER OR RELATING TO THIS AGREEMENT, NOTWITHSTANDING THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT OR ACTIVE OR PASSIVE) OF KBR OR ANY MEMBER OF THE KBR GROUP OR ANY THIRD PARTY SERVICE PROVIDER AND WHETHER DAMAGES ARE ASSERTED IN CONTRACT OR TORT, UNDER FEDERAL, STATE OR NON U.S. LAWS OR OTHER STATUTE OR OTHERWISE; PROVIDED, HOWEVER, THAT THE FOREGOING WAIVER SHALL NOT EXTEND TO COVER, AND KBR SHALL BE RESPONSIBLE FOR, SUCH LOSSES CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF KBR, ANY MEMBER OF THE KBR GROUP OR ANY THIRD PARTY SERVICE PROVIDER.

SECTION 2.6 Service Boundaries and Scope. Except as provided in a Schedule for a specific Service: (a) KBR shall be required to provide, or cause to be provided, the Services only at the locations such Services are being provided by any member of the KBR Group for any member of the Halliburton Group immediately prior to the IPO Closing Date; and (b) the Services shall be available only for purposes of conducting the business of the Halliburton Group substantially in the manner it was conducted immediately prior to the IPO

- 4 -

Closing Date. Except as provided in a Schedule for a specific Service, in providing, or causing to be provided, the Services, KBR shall not be obligated to: (i) maintain the employment of any specific employee or hire additional employees; (ii) purchase, lease or license any additional equipment (including, without limitation, computer equipment, software, furniture, furnishings, fixtures, machinery, vehicles, tools and other tangible personal property) that it would not acquire in the ordinary course of business; (iii) make modifications to its existing systems; or (iv) pay any costs related to the transfer or conversion of data of any member of the Halliburton Group.

SECTION 2.8 Transitional Nature of Services; Changes. The parties acknowledge the transitional nature of the Services and that KBR may make changes from time to time in the manner of performing the Services if KBR is making similar changes in performing similar services for members of its own Group and if KBR furnishes to HESI substantially the same notice KBR shall provide members of its own Group respecting such changes.

ARTICLE III

SERVICE CHARGES

SECTION 3.1 Compensation.

(a) General Principles Relating to Charges for Services. Subject to the specific terms of this Agreement, the Services will be charged and paid for on the same general basis as has been heretofore in effect, with the intent that such charges shall approximate the fully allocated direct and indirect costs of providing and discontinuing the Services, but without any element of profit. It is the further intent of the parties that the fully allocated direct and indirect costs incurred by KBR and its subsidiaries in providing Services under this Agreement will be charged on a basis that allocates such costs on a fair and nondiscriminatory basis. The parties shall use good faith efforts to discuss any situation in which the actual charge for a Service is expected significantly to exceed the estimated charge set forth on a Schedule for a particular Service; provided, however, that charges incurred in excess of any such estimate shall not justify ceasing the provision of, or payment for, Services under this Agreement.

(b) Service Fees. In consideration for the provision of a Service, each member of the Halliburton Group receiving Services shall pay to KBR or the member of the KBR Group providing such Services, as applicable, either (i) a mutually agreed fixed fee for such Service or (ii) a reimbursement for all reasonable, out-of-pocket cash costs that are incurred to provide such Service, including, as applicable, one-time set-up costs for Services. The Service fees in effect from the date hereof until December 31, 2006 are set forth on the attached Schedules. The Service fees to be charged for each succeeding calendar year shall be determined annually in connection with the KBR and Halliburton annual planning process or otherwise as the parties may agree. From time to time, the

- 5 -

Service Coordinators may, in accordance with the general principles described in Section 3.1(a), agree in writing to update, modify or amend any Service fee set forth on a Schedule or agreed in connection with the annual planning process or otherwise by the parties. The Service Coordinators may agree on any such update, modification or amendment for any reason, including, but not limited to, error in the Schedule or incorrect estimates, rates, fees or prices in the underlying budget data from which the Service fee was derived.

SECTION 3.2 Performance under Ancillary Agreements. Notwithstanding anything to the contrary contained herein, HESI shall not be charged under this Agreement for any services that are specifically required to be performed under the Separation Agreement or any other Ancillary Agreement and any such other services shall be performed and charged for in accordance with the terms of the Separation Agreement or such other Ancillary Agreement.

ARTICLE IV

PAYMENT

SECTION 4.1 Payment.

(a) Prior to the Distribution and unless otherwise agreed by the mutual agreement of the Service Coordinators with respect to a particular Service, charges for Services shall be paid at the end of each month by intercompany account transfer, consistent with the parties’ standard intercompany account settlement prior to the date of this Agreement. On or before the end of each month, KBR shall deliver to the HESI Service Coordinator and such other persons as he may from time to time designate a memorandum setting forth in reasonable detail for the period covered: (i) the invoice amount for the Services rendered, (ii) the basis for the calculation of the costs, and (iii) such additional information as HESI may reasonably request (the “Fee Memorandum”). Adjustment credits or debits, if any, shall be shown on, and settled concurrently with, the Fee Memorandum next succeeding the Fee Memorandum for which the adjustment is made. Interest will accrue on any unpaid Fee Memorandum amounts at the rate of interest then in effect between HESI and KBR Holdings, LLC for outstanding intercompany account balances, until such amounts, together with all accrued and unpaid interest thereon, are paid in full.

(b) After a Distribution, if any, or upon such time as the parties agree to cease the settlement of amounts due hereunder through intercompany account settlement, KBR shall deliver to HESI, on or before the end of each month, addressed to the attention of the Halliburton Chief Accounting Officer or such other person as HESI may designate in writing, an invoice containing all the information contained in the Fee Memorandum (the “Invoice”). Absent manifest error in the calculations contained in an Invoice (if there is manifest error, HESI will correct such error and show such recalculation), HESI shall wire transfer to the account of KBR, within fifteen (15) days after the date of the Invoice, the invoiced amount in full in accordance with written wiring instructions previously provided by KBR. Adjustment credits or debits shall be shown on, and settled concurrently with, the Invoice next succeeding the Invoice for which the adjustment is made. Interest will accrue on any unpaid Invoice amounts at the rate of LIBOR plus

- 6 -

2.0%, until such amounts, together with all accrued and unpaid interest thereon, are paid in full.

(c) All timely payments under this Agreement shall be made without early payment discount. Any preexisting obligation to make payment for Services provided hereunder shall survive the termination of this Agreement.

SECTION 4.2 Payment Disputes. HESI may object to any amounts for any Service at any time before, at the time of or after payment is made, provided such objection is made in writing to KBR within ninety (90) days following the date of the disputed Fee Memorandum or Invoice, as applicable. HESI must timely pay the disputed items in full pending resolution of the dispute. Payment of any amount shall not constitute approval thereof. The Service Coordinators shall meet as expeditiously as possible to resolve any dispute. Any dispute that is not resolved by the Service Coordinators within forty-five (45) days shall be resolved in accordance with the dispute resolution and arbitration procedures set forth in Article VII of the Separation Agreement. Neither party (or any member of its respective Group) shall have a right of set-off against the other party (or any member of its respective Group) for billed amounts hereunder. Upon written request, KBR will provide to HESI reasonable detail and support documentation to permit HESI to verify the accuracy of a Fee Memorandum or Invoice, as applicable. Certain Services are subject to true-up as set forth in the attached Schedules. In addition, from time to time, the Service Coordinators, by mutual agreement, may conduct a true-up process to adjust other Service charges based on a reconciliation of budgeted usage and costs with the parties’ actual experience.

SECTION 4.3 Error Correction. KBR shall make adjustments to charges as required to reflect the discovery of errors or omissions in charges. Services under this Agreement and charges therefor shall be subject to audit in accordance with Section 4.5 hereof.

SECTION 4.4 Taxes. Any transfer taxes, excises, fees or other charges (including, without limitation, value added, sales, use, or receipts taxes, but not including a tax on or measured by the income, net or gross revenues, business activity, or capital of a member of the KBR Group), or any increase therein, now or hereafter imposed directly or indirectly by law upon any fees paid hereunder for Services, which a member of the KBR Group is required to pay or incur in connection with the provision of Services hereunder (“Tax”), shall be passed on to HESI as an explicit surcharge and shall be paid by HESI in addition to any Service fee payment, whether included in the applicable Service fee payment, or added retroactively. If HESI submits to KBR a timely and valid resale or other exemption certificate acceptable to KBR and sufficient to support the exemption from Tax, then such Tax will not be added to the Service fee payable pursuant to Article III; provided, however, if a member of the KBR Group is ever required to pay such Tax, HESI will promptly reimburse KBR for such Tax, including any interest, penalties, and attorney’s fees related thereto. The parties will cooperate to minimize the imposition of any Taxes.

SECTION 4.5 Records; Audits.

(a) KBR shall maintain true and correct records of all receipts, invoices, reports and such other documents relating to the Services rendered hereunder in

- 7 -

accordance with its standard accounting practices and procedures, consistently applied. Without limiting the generality of the foregoing, KBR’s accounting records shall be maintained in sufficient detail to enable an auditor to verify the accuracy, completeness and appropriateness of the charges for the Services hereunder. KBR shall retain such accounting records and make them available to Halliburton’s auditors for a period of not less than six (6) years from the close of each fiscal year of KBR; provided, however, that KBR may, at its option, transfer such accounting records to HESI upon termination of this Agreement.

(b) Upon written request, HESI and its duly authorized representatives shall have access during customary business hours to the accounting records and other documents maintained by the KBR Group that relate to this Agreement and shall have the right to audit such records; provided, however, that the same period cannot be re-audited. Any dispute arising out of an audit that is not resolved by the mutual agreement of the Service Coordinators shall be resolved in accordance with the dispute resolution and arbitration procedures set forth in Article VII of the Separation Agreement.

ARTICLE V

TERM

SECTION 5.1 Term. HESI shall undertake to provide to itself and members of the Halliburton Group, and to terminate as soon as reasonably practicable in accordance with Article VI, the Services provided to HESI or any member of the Halliburton Group hereunder. Except as otherwise expressly agreed or unless sooner terminated, this Agreement shall continue in full force and effect between the parties for so long as any Service set forth in any Schedule hereto is being provided to HESI or any member of the Halliburton Group and this Agreement shall terminate upon the cessation of all Services provided hereunder. Notwithstanding the foregoing, each Service shall be provided until the date set forth in the relevant Schedule for such Service, unless such Service is terminated prior to such date by HESI pursuant to Article VI or by mutual agreement of the parties.

ARTICLE VI

After the date hereof, HESI may, without cause and in accordance with the terms and conditions hereunder, request the discontinuation of one or more specific Services or all of the Services provided thereunder by giving KBR at least thirty (30) days prior written notice; provided, however, that (i) HESI shall be liable to KBR for all costs and expenses KBR or any member of the KBR Group remains obligated to pay in connection with, and attributable to, the provision of the discontinued Service or Services and (ii) KBR shall use reasonable best efforts to minimize all such costs and expenses. HESI may request partial discontinuation of a Service and KBR shall use reasonable best efforts to accommodate such request. In such case, by mutual agreement, the parties may agree to partial discontinuation of a Service and a corresponding reduction in consideration payable therefor pursuant to Article III. The parties shall cooperate as reasonably required to effectuate an orderly and systematic transfer to the Halliburton Group of all of the duties and

- 8 -

obligations previously performed by KBR or a member of the KBR Group under this Agreement.

SECTION 6.2 Procedures Upon Discontinuation or Termination of Services. Upon the discontinuation or termination of a Service hereunder, this Agreement shall be of no further force and effect with respect to such Service, except as to obligations accrued prior to the date of discontinuation or termination; provided, however, that Article I, Article VIII and Article IX of this Agreement shall survive such discontinuation or termination. Each party and the applicable member(s) of its respective Group shall, within sixty (60) days after discontinuation or termination of a Service, to the extent reasonably practicable, deliver to the other party and the applicable member(s) of its respective Group all property in its possession, including but not limited to (i) originals of all books, records, contracts, receipts for deposits and all other papers or documents in its possession which pertain exclusively to the business of the other party and relate to such Service, and (ii) copies of books, records, contracts, receipts for deposits and all other papers or documents maintained by the other party and which pertain in part, to the business of the other party and relate to such Service; provided that a party may retain archival copies of material provided to the other party pursuant to this Section 6.2.

ARTICLE VII

DEFAULT

SECTION 7.1 Termination for Default. In the event (i) of a failure of HESI to pay for Services in accordance with the terms of this Agreement, (ii) of a failure of KBR to perform, or cause to be performed, the Services in accordance with the terms of this Agreement which failure results or could reasonably result in a material adverse impact on the business, operations or financial results of the Halliburton Group taken as a whole, or (iii) any party shall default, in any material respect, in the due performance or observance by it of any of the other terms, covenants or agreements contained in this Agreement, then the non-defaulting party shall have the right, at its sole discretion, to immediately terminate this Agreement if the defaulting party has (A) failed to cure the default within thirty (30) days of receipt of the written notice of such default or, (B) if such default is not reasonably susceptible to cure within a 30-day period, failed to take action within thirty (30) days of receipt of the written notice of default reasonably designed to cure such default as soon as is reasonably practicable. HESI’s right to terminate this Agreement set forth in (ii) and (iii) above and the rights set forth in Section 2.5 shall constitute HESI’s sole and exclusive rights and remedies for a breach by KBR hereunder (including without limitation any breach caused by an Affiliate of KBR or other third party providing a Service hereunder).
