Halliburton or any member of the Halliburton Group, on the other hand (including any contractual agreements or arrangements existing or alleged to exist between or among any such members on or before the Separation Time). At any time, at the request
of any other party, each party shall cause each member of its respective Group to execute and deliver releases reflecting the provisions hereof.

(iii) provided by KBR to Halliburton specifically for inclusion in Halliburton’s annual or quarterly reports following the IPO Closing Date. 
 As
used in this Section 3.2, “Appropriate Members of the KBR Group” means the member or members of the KBR Group, if any, whose acts, conduct or omissions or failures to act caused, gave rise to or resulted in the Loss from and
against which indemnity is provided. 
 3.3 Indemnification by Halliburton. Except as provided in this Article III, Halliburton and
the Appropriate Members of the Halliburton Group shall indemnify, defend and hold harmless KBR, each member of the KBR Group and their respective successors and assigns (collectively, the “KBR Indemnitees”), from and against any and
all Losses of the KBR Indemnitees relating to, arising out of or resulting from any of the following (without duplication):

to be stated therein or necessary to make the statements therein not misleading, with respect to all information contained in the IPO Registration Statement or any IPO Prospectus provided by Halliburton specifically for inclusion therein and set
forth on Schedule 3.3(f); and 
 (g) the Silica Note and any reimbursement obligations of the Halliburton Group to the
KBR Group with respect thereto. 
 As used in this Section 3.3, “Appropriate Members of the Halliburton Group” means the member or
members of the Halliburton Group, if any, whose acts, conduct or omissions or failures to act caused, gave rise to or resulted in the Loss from and against which indemnity is provided. 
 3.4 Indemnifications Relating to FCPA Subject Matters 
 (a) Halliburton Indemnity. Halliburton agrees to indemnify and hold harmless the KBR FCPA Indemnitees from and against any Penalties (such Penalties hereinafter referred to as “Halliburton Indemnified
FCPA Matters”); provided, that with respect to any KBR FCPA Indemnitee that is not wholly owned, directly or indirectly, by the KBR Group as of the date hereof (a “non-wholly owned majority subsidiary”), the Halliburton
indemnity provided under this Section 3.4(a) shall be limited to that percentage of Penalties assessed against or paid by such non-wholly owned majority subsidiary equal to the KBR Group’s ownership interest in such non-wholly owned
majority subsidiary as of the date hereof. 
 For avoidance of doubt, the Halliburton indemnification provided under this Section 3.4(a) shall not apply
to any losses, claims, liabilities or damages relating to the FCPA Subject Matters that are not Halliburton Indemnified FCPA Matters (and the indemnity provided under Section 3.4(a) will not include any such other losses, claims, liabilities or
damages), regardless of how denominated or the cause of action, whether in tort, contract, a criminal proceeding or otherwise. Without limiting the foregoing, “Halliburton Indemnified FCPA Matters” shall not include, and the indemnity
provided under this Section 3.4(a) shall not apply to: (x) Third-Party FCPA Claims; (y) losses, claims, liabilities or damages that (I) are special, indirect, derivative or consequential, (II) relate to or result in threatened or
actual suspension or debarment from bidding or continued activity under government contracts, (III) relate to alleged or actual damage to business or other reputation or loss of, or adverse effect on, cash flow, assets, goodwill, results of
operations, business, prospects, profits or business value, whether in the present or future, (IV) relate to alleged or actual adverse consequences in obtaining, continuing or termination of financing for current or future projects, and/or
(V) are as a result of claims by directors, officers, employees, Affiliates, advisors, attorneys, agents, debt holders or other interest holders or constituents of KBR or any member of the KBR Group in their capacity as such; or (z) costs
or expenses incurred for any monitor required by or agreed to with, a Governmental Authority to review continued compliance by the KBR Group with Applicable FCPA Law. 
  

 21 

 (b) Sole Beneficiaries. The indemnity provided under Section 3.4(a) is solely
for the benefit of the KBR FCPA Indemnitees, and no provision of this Agreement shall create any third party beneficiary or other rights in any Person or Persons other than the KBR FCPA Indemnitees. 
 (c) Control of Proceedings. Until such time, if ever, that KBR exercises its right to assume control over the investigation,
defense and/or settlement of FCPA Subject Matters with respect to KBR pursuant to Section 3.4(e), Halliburton and its Majority Owned Subsidiaries shall at all times, in their sole discretion, have and maintain control over the investigation,
defense and/or settlement of, any FCPA Subject Matter. Even if KBR exercises its right pursuant to Section 3.4(e) hereof, Halliburton and its Majority Owned Subsidiaries shall at all times, in their sole discretion, have and maintain control
over the investigation, defense and/or settlement of FCPA Subject Matters with respect to Halliburton. Notwithstanding the foregoing, (i) no settlement by KBR of any claims relating to FCPA Subject Matters effected without the prior written
consent of Halliburton will be effective or binding upon Halliburton, any member of the Halliburton Group or their respective successors or assigns, and (ii) no settlement by Halliburton of any claims relating to FCPA Subject Matters effected
without the prior written consent of KBR will be effective or binding upon any KBR FCPA Indemnitee. The parties agree that Halliburton may terminate its indemnity provided under Section 3.4(a) upon the settlement by KBR of any claims relating
to FCPA Subject Matters effected without the prior written consent of Halliburton. 
 (d) Cooperation. At all times
during the term of this Agreement, including whether or not or before or after KBR exercises its right to assume control over the investigation, defense and/or settlement of FCPA Subject Matters pursuant to Section 3.4(e) hereof, KBR, at
Halliburton’s expense, shall use best efforts to assist with Halliburton’s full cooperation with any Governmental Authority in Halliburton’s investigation of FCPA Subject Matters and its investigation, defense and/or settlement of any
Governmental FCPA Claim. Without limiting the foregoing, KBR’s best efforts to assist with Halliburton’s full cooperation contemplated by the preceding sentence shall include: 
 (i) At the request of Halliburton, the voluntary and truthful disclosure to Halliburton, the DOJ, the Commission or other Governmental
Authority of all information in KBR’s possession, custody or control (in any form or medium, including documents) respecting the activities of KBR, Halliburton and its or their current and former directors, officers, employees, agents,
distributors and Affiliates relating to FCPA Subject Matters about which Halliburton inquires or which is material to the investigation conducted by Halliburton, the DOJ, the Commission or other Governmental Authority into the FCPA Subject Matters.

 (ii) At the written request of Halliburton, the voluntary production to Halliburton, the DOJ, the Commission or other
Governmental Authority, of all documents, records or other tangible evidence in KBR’s possession, custody or control relating to FCPA Subject Matters. Without limiting the foregoing, KBR will assemble, organize and produce, or take reasonable
steps to effectuate the production of, all documents, records, or other tangible evidence related to FCPA Subject Matters in KBR’s possession, custody, or control in such reasonable 

  

 22 

 
format as Halliburton, the DOJ, the Commission or other Governmental Authority requests. KBR shall preserve, maintain and retain all such documents, records
and other tangible evidence related to FCPA Subject Matters. KBR shall provide Halliburton access to all electronic mail, metadata, computer hard drives, computer tape or other electronic data necessary to answer a subpoena of any Governmental
Authority. 
 (iii) At the request of Halliburton, the provision of access to copies of KBR’s original documents and
records relating to FCPA Subject Matters in KBR’s possession, custody or control and, using reasonable best efforts, in the custody or control of all current and former directors, officers, employees, agents, distributors, attorneys and
Affiliates. 
 (iv) At the written request of Halliburton, using reasonable best efforts, (A) making available any of
KBR’s current and former directors, officers, employees, agents, distributors, attorneys and Affiliates who may have been involved in FCPA Subject Matters and whose cooperation is requested by Halliburton, the DOJ, the Commission or other
Governmental Authority; (B) recommending orally and in writing that any and all such Persons cooperate fully (including by appearing for interviews with Governmental Authorities or testimony, including sworn testimony before a grand jury) with
(x) any investigation conducted by Halliburton, the DOJ, the Commission or other Governmental Authority with respect to FCPA Subject Matters, or (y) any prosecution of individuals (including without limitation the cooperation of current or
former directors, officers or employees of KBR who are not defendants in the prosecution) or entities; and (C) taking appropriate disciplinary action with respect to such of KBR’s current and former directors, officers, employees, agents,
distributors and Affiliates who do not cooperate, or who cease to cooperate, fully as contemplated herein. 
 (v) At the
written request of Halliburton, the provision of testimony and other information deemed necessary by Halliburton to identify or establish the original location, authenticity or other evidentiary foundation necessary to admit into evidence documents
in any criminal or other proceeding as requested by Halliburton related to FCPA Subject Matters. 
 (vi) At the written
request of Halliburton, using reasonable best efforts, the provision of access to the outside accounting and legal consultants of KBR whose work includes or relates to FCPA Subject Matters, as well as the records, reports and documents of those
outside consultants related to FCPA Subject Matters. 
 (vii) At the request of Halliburton, KBR shall not assert a claim of
attorney-client or work-product privilege as to: (i) any KBR original documents or records, or any copies thereof, in possession of attorneys of KBR relating to FCPA Subject Matters, (ii) any memoranda of witness interviews (including
exhibits thereto) by attorneys or employees of KBR relating to FCPA Subject 

  

 23 

 
Matters; (iii) due diligence reports by attorneys of KBR relating to agents of KBR that are or have been created contemporaneously with and related to
transactions or events underlying FCPA Subject Matters; or (iv) documents that are or have been created by attorneys of KBR in connection with internal investigations by Halliburton or KBR into FCPA Subject Matters. 
 Notwithstanding anything to the contrary contained in this Agreement, in making production of any documents, disclosure of any information or available any people,
pursuant to this Section 3.4(d), KBR shall not be required to (1) expressly or implicitly waive its right to assert any privilege that is available under law against Persons other than the Governmental Authority at issue concerning the
documents or information at issue or the subject matters thereof; or (2) produce, disclose or make available any legal advice or attorney work product relating to or given in connection with (A) internal investigations by Halliburton or
KBR; (B) investigations conducted by any Governmental Authority, proceedings related thereto or resulting therefrom; or (C) any Third-Party Claims. 
 KBR shall promptly inform and disclose to Halliburton any developments, communications or negotiations between KBR, on the one hand, and any Governmental Authority or third party, on the other hand, with respect to FCPA Subject Matters,
except as prohibited by law or lawful order of a Governmental Authority. Halliburton may terminate its indemnity provided under Section 3.4(a) upon the material breach by KBR of its obligations under this Section 3.4(d); provided, however,
that if, despite using KBR’s best efforts or reasonable best efforts, as the case may be, to assist with Halliburton’s full cooperation in accordance with this Section 3.4(d), KBR is unable to achieve the desired goal contemplated by
any of the foregoing subsections (i)-(vii), Halliburton shall not have grounds to terminate such indemnity. Termination of Halliburton’s indemnity provided under Section 3.4(a) pursuant to this Section 3.4(d) shall not preclude
Halliburton from pursuing any other rights or seeking any and all other available remedies against KBR for material breach by KBR of its obligations under this Section 3.4(d). 
 (e) Assumption of Control by KBR; Refusal of Settlement. KBR, by written notice to Halliburton, may (i) take control over the
investigation, defense and/or settlement of FCPA Subject Matters with respect to KBR or (ii) refuse (in KBR’s sole discretion) to agree to a settlement of FCPA Subject Matters negotiated and presented by Halliburton. In either such event,
Halliburton may terminate its indemnity provided under Section 3.4(a). Notwithstanding the foregoing, a member of the KBR Group that is not a Majority Owned Subsidiary as of the date hereof may control the investigation, defense and/or
settlement of FCPA Subject Matters solely with respect to such subsidiary, and may agree to a settlement of FCPA Subject Matters solely with respect to such subsidiary without the prior written consent of Halliburton, and any such control or
agreement to a settlement shall not allow Halliburton to terminate its indemnity provided under Section 3.4(a). 
 (f)
No Admission. Each of Halliburton and KBR do not, by the making of the indemnities in this Section 3.4 or by any other provision of this Agreement, concede that it or any of its Affiliates have violated applicable Law. 
 (g) Expenses. Until such time, if ever, that KBR exercises its right to assume control over the investigation, defense and/or
settlement of FCPA Subject Matters pursuant to 

  

 24 

 
Section 3.4(e), Halliburton shall bear, at its sole expense, all attorneys’, accountants’, consultants’ and other professionals’
fees and expenses and all other costs incurred on behalf of Halliburton and KBR in the investigation, defense, and/or settlement of FCPA Subject Matters, except as contemplated by Section 3.11. After such time, if ever, that KBR exercises its
right to assume control over the investigation, defense and/or settlement of FCPA Subject Matters pursuant to Section 3.4(e), Halliburton shall continue to bear, at its sole expense, all attorneys’, accountants’, consultants’,
and other professionals’ fees and expenses and all other costs incurred on its own behalf in the investigation, defense, and/or settlement of FCPA Subject Matters, but shall no longer be responsible for such fees, expenses and costs incurred on
behalf of KBR. Nothing in this Section 3.4(g) shall prohibit KBR from at any time engaging (at KBR’s own expense) its own legal advisors, accountants, consultants or other professionals with respect to the FCPA Subject Matters. 

(h) Communication. Notwithstanding the rights and obligations set forth in Section 3.4(d), each of Halliburton and KBR
agrees to provide, or cause to be provided, to each other as soon as reasonably practicable after written request therefor, any Information relating to FCPA Subject Matters in the possession or under the control of such party that the requesting
party reasonably needs (i) to comply with reporting, disclosure, filing or other requirements imposed on the requesting party (including under applicable securities laws) by a Governmental Authority having jurisdiction over the requesting
party, (ii) for use in any Regulatory Proceeding, judicial proceeding or other proceeding or in order to satisfy audit, accounting, claims, regulatory, litigation or other similar requirements, (iii) to allow the other party to
investigate, defend and/or settle any Governmental FCPA Claim or Third-Party FCPA Claim for which such party is responsible under this Agreement, or (iv) to comply with its obligations under this Agreement or any Ancillary Agreement; provided,
however, that in the event that any party determines that any such provision of Information could violate any Law or agreement, or waive any attorney-client or work-product privilege other than as contemplated by Section 3.4(d)(vii), the
parties shall take all reasonable measures to permit the compliance with such obligations in a manner that avoids any such harm or consequence. Until such time, if ever, that KBR exercises its right pursuant to Section 3.4(e) hereof,
Halliburton shall provide to KBR copies of all correspondence between Halliburton and any Governmental Authority with respect to the FCPA Subject Matters insofar as such correspondence relates to KBR. In addition, until such time, if ever, that KBR
exercises its right pursuant to Section 3.4(e) hereof, from time to time and upon KBR’s reasonable request, the attorneys, accountants, consultants or other advisors of the Board of Directors of Halliburton or any special committee of
independent directors thereof shall brief the Board of Directors of KBR, the special committee of independent directors formed pursuant to Section 5.3(c) or the agents or representatives of either of them, concerning the status of or issues
arising under or relating to Halliburton’s investigation of FCPA Subject Matters and its defense and/or settlement of any Governmental FCPA Claim. 
 (i) Procedures for Foreign Agents. The parties agree that Halliburton may terminate its indemnity provided under Section 3.4(a) upon the material breach by KBR of its obligations under
Section 8.14(b). 
  

 25 

 3.5 Indemnifications Relating to Barracuda-Caratinga Project. 
 (a) Halliburton Indemnity. Halliburton agrees to indemnify and hold harmless the KBR B-C Indemnitees from and against (i) all
out-of-pocket cash costs and expenses they incur after the date hereof as a result of the replacement of the subsea flow-line bolts installed in connection with the development of the Barracuda-Caratinga Project, and (ii) any cash damages,
losses, liabilities, obligations, judgments, claims, payments, interest costs, expenses or other award assessed against the KBR B-C Indemnitees in connection with the arbitration of the Barracuda-Caratinga Bolts Matter, and/or any cash settlement or
compromise amounts agreed to in lieu thereof (the foregoing (i) and (ii), the “Halliburton Indemnified Barracuda-Caratinga Matters”). 
 For avoidance of doubt, the Halliburton indemnification provided under this Section 3.5(a) shall not apply to any other losses, claims, liabilities or damages relating to the Barracuda-Caratinga Project that are
not Halliburton Indemnified Barracuda-Caratinga Matters (and the indemnity provided under Section 3.5(a) will not include any such other losses, claims, liabilities or damages), regardless of how denominated or the cause of action, whether in
tort, contract, a criminal proceeding or otherwise. Without limiting the foregoing, “Halliburton Indemnified Barracuda-Caratinga Matters” shall not include, and the Halliburton indemnity provided under this Section 3.5(a) shall not
apply to: (x) Third Party Claims other than claims commenced by Barracuda & Caratinga Leasing Company B.V. or Affiliates of Petrobras with respect to the Barracuda-Caratinga Bolts Matter, or (y) losses, claims, liabilities or
damages that (I) are special, indirect, derivative or consequential, (II) relate to alleged or actual damage to business or other reputation or loss of, or adverse effect on, cash flow, assets, goodwill, results of operations, business,
prospects, profits or business value, whether in the present or future, or (III) relate to alleged or actual adverse consequences in obtaining, continuing or termination of financing for current or future projects. 
 (b) Sole Beneficiaries. The indemnity provided under Section 3.5(a) is solely for the benefit of the KBR B-C Indemnitees, and
no provision of this Agreement shall create any third party beneficiary or other rights in any Person or Persons other than the KBR B-C Indemnitees. 
 (c) Control of Proceedings. Until such time, if ever, that Halliburton exercises its right pursuant to Section 3.5(e) hereof, the KBR B-C Indemnitees shall at all times, in their sole discretion, have and
maintain control over the defense, counterclaim and/or settlement of the Barracuda-Caratinga Bolts Matter in respect of which indemnity may be sought under Section 3.5(a). Notwithstanding the foregoing, (i) no settlement by KBR of any
claims relating to the Barracuda-Caratinga Bolts Matter effected without the prior written consent of Halliburton will be effective or binding upon Halliburton, any member of the Halliburton Group or their respective successors and assigns, and
(ii) no settlement by Halliburton of any claims relating to the Barracuda-Caratinga Bolts Matter effected without the prior written consent of KBR will be effective or binding upon any KBR B-C Indemnitee. The parties agree that Halliburton may
terminate its indemnity provided under Section 3.5(a) upon the settlement by KBR of any claims relating to the Barracuda-Caratinga Bolts Matter effected without the prior written consent of Halliburton. 
 (d) Cooperation; Provision of Information. Upon such time, if ever, that Halliburton exercises its right pursuant to
Section 3.5(e), KBR shall use best efforts to fully 

  

 26 

 
cooperate with Halliburton in the defense, counterclaim and/or settlement of the Barracuda-Caratinga Bolts Matter. At all times under this Agreement, KBR
shall promptly inform and disclose to Halliburton any developments, communications or negotiations between KBR, on the one hand, and Petrobras, its Affiliates or any third party, on the other hand, with respect to the Barracuda-Caratinga Bolts
Matter, except as prohibited by law or lawful order of a government or Governmental Authority or a court of competent jurisdiction. Halliburton may terminate its indemnity provided under Section 3.5(a) upon the material breach by KBR of its
obligations under this Section 3.5(d). Termination of the Halliburton indemnity provided under Section 3.5(a) pursuant to this Section 3.5(d) shall not preclude Halliburton from pursuing any other rights or seeking any and all other
available remedies against KBR for material breach by KBR of its obligations under this Section 3.5(d). 
 (e)
Assumption of Control by Halliburton; Refusal of Settlement. Halliburton, by written notice to KBR, may (i) take control over the defense, counterclaim and/or settlement of the Barracuda-Caratinga Bolts Matter or (ii) refuse (in
Halliburton’s sole discretion) to agree to a settlement of the Barracuda-Caratinga Bolts Matter negotiated and presented by KBR. If Halliburton exercises its right pursuant to this Section 3.5(e) to control the defense, counterclaim and/or
settlement of the Barracuda-Caratinga Bolts Matter, and KBR refuses to agree to a settlement of the Barracuda-Caratinga Bolts Matter negotiated and presented by Halliburton, Halliburton may terminate its indemnity provided under Section 3.5(a).

 (f) Expenses. Until such time, if ever, that Halliburton exercises its right to assume control over the defense,
counterclaim and/or settlement of the Barracuda-Caratinga Bolts Matter pursuant to Section 3.5(e), KBR shall bear, at its sole expense, all attorney’s, accountants’, consultants’ and other professionals’ fees and expenses
and other costs incurred on behalf of Halliburton and KBR in the defense, counterclaim and/or settlement of the Barracuda-Caratinga Bolts Matter, except as contemplated by Section 3.11. Nothing in this Section 3.5(f) shall prohibit
Halliburton from at any time engaging (at Halliburton’s own expense) its own legal advisors, accountants, consultants or other professionals with respect to the Barracuda-Caratinga Bolts Matter. 
 (g) Master Intercompany Reimbursement Agreement. The parties agree that the rights and obligations set forth in this
Section 3.5 shall supersede the rights and obligations of the parties under, and control over, the Master Intercompany Reimbursement Agreement dated as of December 16, 2005 between Halliburton and KBR Holdings, LLC solely with respect to
the Barracuda-Caratinga Bolts Matter. 
 (h) Communication. Each of Halliburton and KBR agrees to provide, or cause to
be provided, to each other as soon as reasonably practicable after written request therefor, any Information relating to the Barracuda-Caratinga Bolts Matters in the possession or under the control of such party that the requesting party reasonably
needs (i) to comply with reporting, disclosure, filing or other requirements imposed on the requesting party (including under applicable securities laws) by a Governmental Authority having jurisdiction over the requesting party, (ii) for
use in any Regulatory Proceeding, judicial proceeding or other proceeding or in order to satisfy audit, accounting, claims, regulatory, litigation or other similar requirements, (iii) to allow the other party to defend, counterclaim and/or
settle the Barracuda-Caratinga Bolts Matter or any Third Party Claim relating to the Barracuda-Caratinga Bolts 

  

 27 

 
Matter for which such party is responsible under this Agreement, or (iv) to comply with its obligations under this Agreement or any Ancillary Agreement;
provided, however, that in the event that any party determines that any such provision of Information could violate any law or agreement, or waive any attorney-client or work-product privilege, the parties shall take all reasonable measures to
permit the compliance with such obligations in a manner that avoids any such harm or consequence. In addition, until such time, if ever, that Halliburton exercises its right pursuant to Section 3.5(e) hereof, from time to time and upon
Halliburton’s reasonable request, the attorneys, accountants, consultants or other advisors of the Board of Directors of KBR or any special committee of independent directors thereof shall brief members of Halliburton senior management, the
Board of Directors of Halliburton or any special committee of independent directors thereof concerning the status of or issues arising under or relating to KBR’s defense, counterclaim and/or settlement of the Barracuda-Caratinga Bolts Matters.

 (i) Arbitration Recovery. The parties agree that KBR shall be entitled to retain the cash proceeds of any judgment,
decision or award entered in favor of a member of the Halliburton Group and/or the KBR Group (including any judgment, decision or award for any counterclaim), or any cash settlement or compromise in lieu thereof received from Petrobras or its
Affiliate by a member of the Halliburton Group and/or the KBR Group, in connection with the Barracuda-Caratinga Bolts Matter; provided, however, that Halliburton shall be entitled to any portion of such judgment, decision or award or any settlement
or compromise amount (i) which is designated by an arbitration panel or otherwise agreed by Petrobras or its Affiliate with Halliburton and/or KBR to constitute recovery of legal fees, costs or expenses paid by Halliburton or advanced to KBR by
Halliburton and (ii) which constitutes recovery by KBR of out-of-pocket cash costs and expenses advanced to KBR by Halliburton or paid by Halliburton pursuant to the Halliburton indemnity provided under Section 3.5(a). 
 3.6 Indemnification Obligations Net of Insurance Proceeds and Other Amounts. 
 (a) The parties intend that any Loss subject to indemnification or reimbursement pursuant to this Article III will be net of Insurance
Proceeds that actually reduce the amount of the Loss. Accordingly, the amount which any party (an “Indemnifying Party”) is required to pay to any Person entitled to indemnification under this Article III (an
“Indemnitee”) will be reduced by any Insurance Proceeds theretofore actually recovered by or on behalf of the Indemnitee in reduction of the related Loss. If an Indemnitee receives a payment (an “Indemnity Payment”)
required by this Agreement from an Indemnifying Party in respect of any Loss and subsequently receives Insurance Proceeds, then the Indemnitee will pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received over
the amount of the Indemnity Payment that would have been due if the Insurance Proceeds recovery had been received, realized or recovered before the Indemnity Payment was made. Notwithstanding anything to the contrary in the Transition Services
Agreements, the parties agree that if any such Insurance Proceeds were paid by an insurance company under a plan, such as a retrospective premium or large deductible program, where such Insurance Proceeds are subsequently billed back to one of the
parties by the insurance company, then (i) if billed to the Indemnifying Party, it will pay the insurance company and will not charge such amount to the Indemnitee, or (ii) if billed to the Indemnitee, the Indemnifying Party will pay on
behalf of or reimburse, as appropriate, the Indemnitee for such amount. 
  

 28 

 (b) An insurer who would otherwise be obligated to pay any claims shall not be relieved
of the responsibility with respect thereto or, solely by virtue of the indemnification provisions hereof, have any subrogation rights with respect thereto, it being expressly understood and agreed that no insurer or any other third party shall be
entitled to a “windfall” (i.e., a benefit they would not be entitled to receive in the absence of these indemnification provisions) by virtue of the indemnification provisions herein. Nothing contained in this Agreement or any Ancillary
Agreement shall obligate any member of any Group to seek to collect or recover any Insurance Proceeds. 
 3.7 Procedures for
Indemnification of Third Party Claims. 
 (a) If an Indemnitee shall receive notice or otherwise learn of the assertion by
a Person (including any Governmental Authority) who is not a member of the Halliburton Group or the KBR Group of any claims or of the commencement by any such Person of any Action (collectively, a “Third Party Claim”) with respect
to which an Indemnifying Party may be obligated to provide indemnification to such Indemnitee pursuant to this Article III, such Indemnitee shall give such Indemnifying Party written notice thereof within 20 days after becoming aware of such Third
Party Claim. Any such notice shall describe the Third Party Claim in reasonable detail. Notwithstanding the foregoing, the failure of any Indemnitee or other Person to give notice as provided in this Section 3.7(a) shall not relieve the related
Indemnifying Party of its obligations under this Article III, except to the extent that such Indemnifying Party is actually prejudiced by such failure to give notice. 
 (b) An Indemnifying Party may elect to defend (and, unless the Indemnifying Party has specified any reservations or exceptions, to seek to
settle or compromise), at such Indemnifying Party’s own expense and by such Indemnifying Party’s own counsel, any Third Party Claim for which indemnification is available under this Article III. Within 30 days after the receipt of notice
from an Indemnitee in accordance with Section 3.7(a) (or sooner, if the nature of such Third Party Claim so requires), the Indemnifying Party shall notify the Indemnitee of its election whether the Indemnifying Party will assume responsibility
for defending such Third Party Claim, which election shall specify any reservations or exceptions. After notice from an Indemnifying Party to an Indemnitee of its election to assume the defense of a Third Party Claim, such Indemnitee shall have the
right to employ separate counsel and to participate in (but not control) the defense, compromise or settlement thereof, but the fees and expenses of such counsel shall be the expense of such Indemnitee except as set forth in the next sentence. In
the event that the Indemnifying Party has elected to assume the defense of a Third Party Claim for which indemnification is available under this Article III but has specified, and continues to assert, any reservations or exceptions in such notice,
then, in any such case, the reasonable fees and expenses of one separate counsel for all Indemnitees shall be borne by the Indemnifying Party. 
 (c) If an Indemnifying Party elects not to assume responsibility for defending a Third Party Claim for which indemnification is available under this Article III, or fails to notify an Indemnitee of its election as
provided in Section 3.7(b), such Indemnitee may defend such Third Party Claim at the cost and expense (including allocated costs of in-house counsel and other personnel) of the Indemnifying Party. 
  

 29 

 (d) Unless the Indemnifying Party has failed to assume the defense of the Third Party
Claim for which indemnification is available under this Article III in accordance with the terms of this Agreement, no Indemnitee may settle or compromise such Third Party Claim without the consent of the Indemnifying Party. 
 (e) Except with respect to Halliburton Indemnified FCPA Matters and the Barracuda-Caratinga Bolts Matter, which shall be governed by
Section 3.4 and Section 3.5 respectively, no Indemnifying Party shall consent to entry of any judgment or enter into any settlement of the Third Party Claim without the consent of an Indemnitee if the effect thereof is to permit any
injunction, declaratory judgment, other order or other nonmonetary relief to be entered, directly or indirectly, against such Indemnitee. 
 (f) In the event of payment by or on behalf of any Indemnifying Party to any Indemnitee in connection with any Third Party Claim under this Article III, such Indemnifying Party shall be subrogated to and shall stand
in the place of such Indemnitee as to any events or circumstances in respect of which such Indemnitee may have any right, defense or claim relating to such Third Party Claim against any claimant or plaintiff asserting such Third Party Claim or
against any other person. Such Indemnitee shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense (including allocated costs of in-house counsel and other personnel) of such Indemnifying Party, in prosecuting
any subrogated right, defense or claim. In the event of an Action in which the Indemnifying Party is not a named defendant, if either the Indemnitee or Indemnifying Party shall so request, the parties shall endeavor to substitute the Indemnifying
Party for the named defendant, if at all practicable. If such substitution or addition cannot be achieved for any reason or is not requested, the named defendant shall allow the Indemnifying Party to manage the Action as set forth in this
Section 3.7 and the Indemnifying Party shall fully indemnify the named defendant against all costs of defending the Action (including court costs, sanctions imposed by a court, attorneys’ fees, experts’ fees and all other external
expenses, and the allocated costs of in-house counsel and other personnel), the costs of any judgment or settlement, and the costs of any interest or penalties relating to any judgment or settlement. 
 3.8 Additional Matters. (a) Any claim under this Article III on account of a Loss which does not result from a Third Party Claim shall be
asserted by written notice given by the Indemnitee to the Indemnifying Party. Such Indemnifying Party shall have a period of 30 days after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not respond within
such 30-day period, such Indemnifying Party shall be deemed to have refused to accept responsibility to make payment. If such Indemnifying Party does not respond within such 30-day period or rejects such claim in whole or in part, such Indemnitee
shall be free to pursue such remedies as may be available to such party as contemplated by this Agreement and the Ancillary Agreements. 
 (b) THE PARTIES UNDERSTAND AND AGREE THAT THE INDEMNIFICATION OBLIGATIONS HEREUNDER AND UNDER THE ANCILLARY AGREEMENTS MAY INCLUDE INDEMNIFICATION FOR LOSSES RESULTING FROM, OR ARISING OUT OF, DIRECTLY OR
INDIRECTLY, AN INDEMNIFIED PARTY’S OWN NEGLIGENCE OR STRICT LIABILITY. 
  

 30 

 (c) The provisions of Sections 3.2 through 3.8 shall not apply with respect to
indemnification or indemnification procedures concerning: Taxes (which are governed exclusively by the Tax Sharing Agreement), employee benefits matters (which are governed exclusively by the Employee Matters Agreement), intellectual property
matters (which are governed exclusively by the Intellectual Property Matters Agreement) or services provided under the Transition Services Agreements (which are governed exclusively by the Transition Services Agreements). 
 3.9 Remedies Cumulative. The remedies provided in this Article III shall be cumulative and, subject to the provisions of Article VII, shall not
preclude assertion by any Indemnitee of any other rights or the seeking of any and all other remedies against any Indemnifying Party. 
 3.10
Survival of Indemnities. The rights and obligations of each of Halliburton and KBR and their respective Indemnitees under this Article III shall survive the sale or other transfer by any party of any assets or businesses or the assignment by
it of any Liabilities. 
 3.11 Indemnification of Directors and Officers. It is the parties’ intent that each of KBR and
Halliburton, as applicable, shall be responsible for the costs and expenses incurred pursuant to any indemnification obligations to its current and former officers, directors, employees and agents. To the extent that a party’s current or former
officer, director, employee or agent shall receive indemnification or an advancement of funds from the other party (the party so indemnifying or advancing funds, the “advancing party”) pursuant to an indemnification obligation of
the advancing party to such person under its certificate of incorporation or by-laws, an employment agreement or otherwise, then the advancing party shall be reimbursed promptly and in full by the other party. The parties agree that reimbursement
pursuant to this Section 3.11 shall not be construed to expand or limit the parties’ respective indemnification rights and obligations under this Article III or to confer upon any Person any rights of indemnification. For purposes of this
Section 3.11, persons who serve on the Board of Directors of KBR and who serve as officers of Halliburton after the IPO Closing Date shall be deemed to be directors and officers of Halliburton. 
 3.12 Mitigation of Damages. The parties each agree to attempt to mitigate, and to cause each of the members of their respective Groups to attempt
to mitigate, any Losses that such party may suffer as a consequence of any matter giving rise to a right to indemnification under this Article III by taking all actions which a reasonable person would undertake to minimize or alleviate the amount of
Losses and the consequences thereof, as if such person would be required to suffer the entire amount of such Losses and the consequences thereof by itself, without recourse to any remedy against another person, including pursuant to any right of
indemnification hereunder.

 33 

 ARTICLE V 
 CORPORATE GOVERNANCE AND OTHER MATTERS 
 5.1 Charter and Bylaws. As of the IPO Closing Date, the KBR
Charter and Amended and Restated Bylaws of KBR shall be in the forms of Schedule 5.1(a) and Schedule 5.1(b), respectively, with such changes therein as may be agreed to in writing by Halliburton. 
 5.2 KBR Board Representation. 
 (a) Beginning on the IPO Closing Date, and for so long as the Halliburton Group beneficially owns shares of KBR Common Stock representing a majority of the total voting power of all of the outstanding KBR Voting Stock, Halliburton shall
have the right to designate for nomination by the KBR Board (or any nominating committee thereof) for election to the KBR Board (each person so designated, a “Halliburton Designee”) a majority of the members of the KBR Board,
including the Chairman of the Board. For so long as the Halliburton Group beneficially owns shares of KBR Common Stock representing less than a majority but at least 15% of the total voting power of all of the outstanding shares of KBR Voting Stock,
Halliburton shall have the right to designate for nomination by the KBR Board (or any nominating committee thereof) for election to the KBR Board a proportionate number of Halliburton Designees to the KBR Board, as calculated in accordance with
Section 5.2(d). Notwithstanding anything to the contrary set forth herein, (i) KBR’s obligations with respect to the election or appointment of Halliburton Designees shall be limited to the obligations set forth under this
Section 5.2 and (ii) shall be further limited by KBR’s compliance with Law and any applicable Commission or stock exchange director independence requirements. 
 (b) For so long as the Halliburton Group beneficially owns shares of KBR Common Stock representing a majority of the total voting power of
all of the outstanding shares of KBR Voting Stock, KBR shall use reasonable best efforts to avail itself of the “Controlled Companies” exemption set forth in Rule 303A of the NYSE Listed Company Manual, and any exemption to any analogous
Commission rule or requirement, to exempt KBR from compliance with corporate governance requirements relating to director independence. For so long as the Halliburton Group beneficially owns shares of KBR Common Stock representing a majority of the
total voting power of all of the outstanding shares of KBR Voting Stock, commencing with the annual meeting of stockholders of KBR to be held in 2007 and prior to each annual meeting of stockholders of KBR thereafter, Halliburton shall be entitled
to present to the KBR Board or any nominating committee thereof for nomination thereby such number of Halliburton Designees for election to the KBR Board (or if there is a classified board, the class of directors up for election) at such annual
meeting as would result in Halliburton having the appropriate number of Halliburton Designees on the KBR Board as determined pursuant to this Section 5.2. 
 (c) KBR shall at all such times exercise all authority under applicable Law and use reasonable best efforts to cause all such Halliburton
Designees to be nominated for election as KBR Board members by the KBR Board (or any nominating committee thereof). KBR shall cause each Halliburton Designee for election to the KBR Board to be included in the slate of nominees recommended by the
KBR Board to holders of KBR Common Stock (including at any special meeting of stockholders held for the election of directors) and shall use 

  

 34 

 
reasonable best efforts to cause the election of each such Halliburton Designee, including soliciting proxies in favor of the election of such persons. In
the event that any Halliburton Designee elected to the KBR Board shall cease to serve as a director for any reason, the vacancy resulting therefrom shall be filled by the KBR Board with a substitute Halliburton Designee. In the event that as a
result of any increase in the size of the KBR Board, Halliburton is entitled to have one or more additional Halliburton Designees elected to the KBR Board pursuant to this Section 5.2, the KBR Board shall appoint the appropriate number of such
additional Halliburton Designees. 
 (d) If at any time the Halliburton Group beneficially owns shares of KBR Common Stock
representing less than a majority but at least 15% of the total voting power of all of the outstanding shares of KBR Voting Stock, the number of persons Halliburton shall be entitled to designate for nomination by the KBR Board (or any nominating
committee thereof) for election to the KBR Board shall be equal to the number of directors computed using the following formula (rounded to the nearest whole number): the product of (i) the percentage of the total voting power of all of the
outstanding shares of KBR Voting Stock beneficially owned by the Halliburton Group and (ii) the number of directors then on the KBR Board (assuming no vacancies exist). Notwithstanding the foregoing, if the calculation set forth in the
foregoing sentence would result in Halliburton being entitled to elect a majority of the members of the KBR Board, the formula will be recalculated with the product being rounded down to the nearest whole number; provided, however, that if the
Halliburton Group, at any time, acquires additional shares of KBR Common Stock so that the Halliburton Group beneficially owns shares of KBR Common Stock representing a majority of the total voting power of all of the outstanding shares of KBR
Voting Stock, then the number of persons Halliburton shall be entitled to designate for nomination by the KBR Board (or any nominating committee thereof) for election to the KBR Board shall be adjusted upward, if appropriate as a result of rounding,
in accordance with the provisions of this Section 5.2(d). If the number of Halliburton Designees serving on the KBR Board exceeds the number determined pursuant to the foregoing sentences of this Section 5.2(d) (such difference being
herein called the “Excess Director Number”), then Halliburton in its sole discretion shall instruct such Halliburton Designees (the number of which designees shall be equal to the Excess Director Number) to promptly resign from the
KBR Board, and, to the extent such persons do not so resign, Halliburton shall assist KBR in increasing the size of the KBR Board, so that after giving effect to such increase, the number of Halliburton Designees on the KBR Board is in accordance
with the provisions of this Section 5.2(d). 
 (e) The parties hereto agree that the KBR Board shall consist of seven
directors as of the IPO Closing Date, including at least four Halliburton Designees consisting of Messrs. Albert O. Cornelison, Jr., C. Christopher Gaut, Andrew R. Lane and Mark A. McCollum, and including Mr. William Utt, the KBR President and
CEO. 
 (f) For so long as the Halliburton Group beneficially owns shares of KBR Common Stock representing a majority of the
total voting power of all of the outstanding shares of KBR Voting Stock, the parties agree that the Halliburton Board of Directors will review and approve all KBR Group projects with an estimated value in excess of $250 million. 
  

 35 

 5.3 Committees. 
 (a) Effective as of the IPO Closing Date and for so long as the Halliburton Group beneficially owns shares of KBR Common Stock
representing a majority of the total voting power of all of the outstanding shares of KBR Voting Stock, any committee of the Board of Directors of KBR (other than the Audit Committee and a special committee of independent directors of KBR to be
formed pursuant to Section 5.3(c) hereof) shall, unless Halliburton consents otherwise, be composed of directors at least a majority of which are Halliburton Designees. Effective as of the IPO Closing Date and for so long as the Halliburton
Group beneficially owns shares of KBR Common Stock representing less than a majority but at least 15% of the total voting power of all of the outstanding shares of KBR Voting Stock, each committee of the KBR Board of Directors (other than the Audit
Committee and the special committee of independent directors of KBR to be formed pursuant Section 5.3(c) hereof) shall, unless Halliburton consents otherwise, include at least one Halliburton Designee to the extent permitted by Law or
applicable Commission or stock exchange requirement. 
 (b) The parties agree that the KBR Board shall form and maintain an
executive committee, which committee shall exercise the authority of the KBR Board of Directors when the KBR Board of Directors is not in session in reviewing and approving the analysis, preparation and submission of significant project bids,
managing the review, negotiation and implementation of significant project contracts, and reviewing the business and affairs of the KBR Group to ensure that Halliburton’s business practices and standards with respect to internal controls and
the Halliburton Code of Business Conduct are consistently implemented and maintained by the KBR Group. For so long as the Halliburton Group beneficially owns shares of KBR Common Stock representing a majority of the total voting power of all
outstanding shares of KBR Voting Stock, the executive committee shall consist solely of Halliburton Designees. If at any time the Halliburton Group beneficially owns shares of KBR Common Stock representing less than a majority but at least 15% of
the total voting power of all of the outstanding shares of KBR Voting Stock, then Halliburton shall be entitled to designate for appointment by the Board to the executive committee at least one Halliburton Designee. 
 (c) The parties agree that the KBR Board shall form a special committee of independent directors of KBR which shall exercise the authority
of the KBR Board of Directors with respect to FCPA Subject Matters and the rights and obligations of KBR under Section 3.4 hereof. The members of such special committee shall satisfy in all material respects the independence standards of Rule
303A of the NYSE Listed Company Manual, as if those standards applied. 
 5.4 Subscription Right. 
 (a) KBR hereby grants to Halliburton, on the terms and conditions set forth herein, a continuing right (the “Subscription
Right”) to purchase from KBR, at the times set forth herein: 
 (i) with respect to the issuance of a class or series
of shares of KBR Voting Stock, the number of such shares as is necessary to allow Halliburton to 

  

 36 

 
maintain its Voting Percentage (or, in the case of a class or series not outstanding prior to such issuance, 80% of the total number of shares of such class
or series being issued); and 
 (ii) with respect to the issuance of a class or series of shares of KBR Non-Voting Stock, the
number of such shares as is necessary to allow Halliburton to maintain its Ownership Percentage with respect to such class or series of shares (or, in the case of a class or series not outstanding prior to such issuance, 80% of the total number of
shares of such class or series being issued). 
 The Subscription Right shall be assignable, in whole or in part and from time to time, by Halliburton to any
member of the Halliburton Group or to a Halliburton Transferee pursuant to Section 5.8. The exercise price for each share purchased pursuant to an exercise of the Subscription Right shall be: (i) in the event of the issuance by KBR of
shares in exchange for cash consideration, the per share price paid to KBR in the related Issuance Event (defined below); and (ii) in the event of the issuance by KBR of shares for consideration other than cash, the per share Market Price of
such shares at the Issuance Event Date (defined below). 
 (b) The provisions of Section 5.4(a) hereof notwithstanding,
and subject to Section 5.6 hereof, the Subscription Right granted pursuant to Section 5.4(a) shall not apply and shall not be exercisable in connection with the issuance by KBR of any shares of KBR Common Stock pursuant to any stock option
or other executive, director or employee benefit, compensation or incentive plan maintained by KBR, to the extent such issuance: (i) would not result in Halliburton and other members of the Halliburton Group losing collective control of KBR
within the meaning of Section 368(c) of the Code, (ii) would not cause Halliburton to fail to satisfy the stock ownership requirements of Section 1504(a)(2) of the Code with respect to the stock of KBR or (iii) would not cause a
change of control under the provisions of Section 355(e) of the Code. The Subscription Right granted pursuant to Section 5.4(a) shall terminate if at any time the Voting Percentage, or the Ownership Percentage with respect to any class or
series of KBR Non-Voting Stock, is less than 80%. 
 (c) At least 20 Business Days prior to the issuance of any shares of KBR
Stock (other than pursuant to any stock option or other executive or employee benefit or compensation plan maintained by KBR in the circumstances described in Section 5.4(b) above and other than issuances of shares to any member of the
Halliburton Group) or the first date on which any event could occur that, in the absence of a full or partial exercise of the Subscription Right, would result in a reduction in the Voting Percentage, a reduction in any Ownership Percentage or the
issuance of any shares of a class or series of KBR Non-Voting Stock not outstanding prior to such issuance, KBR will notify Halliburton in writing (a “Subscription Right Notice”) of any plans it has to issue such shares and the date
on which such issuance could first occur (such issuance being referred to herein as an “Issuance Event” and the closing date of such issuance an “Issuance Event Date”). The Subscription Right Notice shall also
specify the number of shares KBR intends to issue or may issue (or, if an exact number is not known, a good faith estimate of the range of shares KBR may issue) and the other terms and conditions of such Issuance Event. 
  

 37 

 (d) The Subscription Right may be exercised by Halliburton (or any member of the
Halliburton Group to which all or any part of the Subscription Right has been assigned) for a number of shares equal to or less than the number of shares the Halliburton Group is entitled to purchase pursuant to Section 5.4(a). The Subscription
Right may be exercised at any time after receipt of an applicable Subscription Right Notice and prior to the applicable Issuance Event Date by the delivery to KBR of a written notice to such effect specifying (i) the number of shares to be
purchased by Halliburton or any member of the Halliburton Group, and (ii) a determination of the exercise price for such shares. Upon any such exercise of the Subscription Right, KBR will, on or prior to the applicable Issuance Event Date,
deliver to Halliburton (or any member of the Halliburton Group designated by Halliburton), against payment therefor, certificates (issued in the name of Halliburton or its permitted assignee hereunder or as directed by Halliburton) representing the
shares being purchased upon such exercise. Payment for such shares shall be made by wire transfer or intrabank transfer of immediately-available funds to such account as shall be specified by KBR, for the full purchase price of such shares.

 (e) Except as provided in Section 5.4(f), any failure by Halliburton to exercise the Subscription Right, or any
exercise for less than all shares purchasable under the Subscription Right, in connection with any particular Issuance Event shall not affect Halliburton’s right to exercise the Subscription Right in connection with any subsequent Issuance
Event; provided, however, that the Voting Percentage and any Ownership Percentage following such Issuance Event in connection with which Halliburton so failed to exercise such Subscription Right in full or in part shall be recalculated to account
for the dilution of Halliburton’s interest. 
 (f) The Subscription Right, or any part thereof, assigned to any member of
the Halliburton Group other than Halliburton, shall terminate in the event that such member ceases to be a Majority Owned Subsidiary of Halliburton for any reason whatsoever. 
 5.5 Issuance of Stock. Notwithstanding anything to the contrary in this Article V, following the IPO Closing Date and until the earliest to occur
of (i) the date of any Distribution or (ii) the date that Halliburton ceases to control KBR within the meaning of Section 368(c) of the Code, without the prior written consent of Halliburton, KBR shall not issue any stock of KBR or
any securities, securities-based awards, options, warrants or rights convertible into or exercisable or exchangeable for stock of KBR if such issuance would cause Halliburton to fail to control KBR within the meaning of Section 368(c) of the
Code, would cause Halliburton to fail to satisfy the stock ownership requirements of Section 1504(a)(2) of the Code with respect to the stock of KBR or would cause a change of control under the provisions of Section 355(e) of the Code.

 5.6 Settlement of KBR Benefit Plan Awards. Following the IPO Closing Date and until the earliest to occur of (i) the date of
any Distribution or (ii) the date that Halliburton ceases to control KBR within the meaning of Section 368(c) of the Code, without the prior written consent of Halliburton, KBR shall not issue any stock of KBR (or any securities,
security-based awards, options, warrants or rights convertible into or exercisable or exchangeable for stock of KBR) in settlement of any award, including without limitation any KBR restricted stock unit, phantom stock, option, stock appreciation
right or other securities-based award, granted pursuant to any stock option or other executive, director or employee benefit, compensation or incentive 

  

 38 

 
plan maintained by KBR. The parties hereby acknowledge and agree that it is their mutual intent that settlement of any such KBR award shall be made in cash,
in treasury shares or via purchase by KBR of KBR Common Stock in the open marketplace. 
 5.7 Applicability of Rights to Parent in the
Event of an Acquisition. In the event KBR merges into, consolidates, sells substantially all of its assets to or otherwise becomes an Affiliate of a Person (other than Halliburton), pursuant to a transaction or series of related transactions in
which Halliburton or any member of the Halliburton Group receives equity securities of such Person (or of any Affiliate of such Person) in exchange for KBR Common Stock held by Halliburton or any member of the Halliburton Group, all of the rights of
Halliburton set forth in this Article V and in Section 8.5 shall continue in full force and effect and shall apply to the Person the equity securities of which are received by Halliburton pursuant to such transaction or series of related
transactions (it being understood that all other provisions of this Agreement will apply to KBR notwithstanding this Section 5.7). KBR agrees that, without the consent of Halliburton, it will not enter into any agreement which will have the
effect set forth in the first clause of the preceding sentence, unless such Person agrees to be bound by the foregoing provision. 
 5.8
Transfer of Halliburton’s Rights Under Article V. Halliburton may transfer all or any portion of its rights under this Article V to a transferee of any KBR Common Stock from any member of the Halliburton Group (a “Halliburton
Transferee”) holding at least 15% of the voting power of all of the outstanding shares of KBR Common Stock. Halliburton shall give written notice to KBR of its transfer of rights under this Article V no later than 30 days after
Halliburton enters into a binding agreement for such transfer of rights. Such notice shall state the name and address of the Halliburton Transferee and identify the amount of KBR Common Stock transferred and the scope of rights being transferred
under this Article V. In connection with any such transfer, the term “Halliburton” as used in this Article V shall, where appropriate to give effect to the assignment of rights and obligations hereunder to such Halliburton Transferee,
be deemed to refer to such Halliburton Transferee. Halliburton and any Halliburton Transferee may exercise the rights under this Article V in such priority, as among themselves, as they shall agree upon among themselves, and KBR shall observe any
such agreement of which it shall have notice as provided above. 
 5.9 Restricted Opportunities Under KBR Charter. For so long as
Article Eighth of the KBR Charter remains in effect in accordance with its current terms, Halliburton, on behalf of itself and each member of the Halliburton Group, hereby agrees to renounce, to the fullest extent permitted by applicable Law, any
and all rights, interest or expectancy with respect to each investment, commercial activity or other opportunity that, in each case, is a “Restricted Opportunity” (as such term is defined in the KBR Charter as in effect on the date
hereof). 
  

 39 

 ARTICLE VI 
 SUBSEQUENT TRANSACTION 
 6.1 Sole Discretion of Halliburton. 
 (a) Halliburton shall, in its sole and absolute discretion, determine whether one or more transfers of its KBR Common Stock or a
Distribution shall occur, the date of the consummation of such transfer(s) or Distribution and all terms of such transfer(s) or Distribution, including, without limitation, the form, structure and terms of any transaction(s), exchange(s) and/or
offering(s) to effect such transfer(s) or Distribution and the timing of and conditions to the consummation of such transfer(s) or Distribution. In addition, Halliburton may at any time decide to abandon such transfer(s) or Distribution or to modify
or change the terms of such transfer(s) or Distribution, including, without limitation, by accelerating or delaying the timing of the consummation of all or part of such transfer(s) or Distribution. In the case of a Distribution, this Agreement is
intended to be, and is hereby adopted as, a plan of reorganization under Section 368 of the Code. 
 (b) Halliburton
shall select any investment banker(s) and manager(s) in connection with the transfer(s) or Distribution, as well as any financial printer, solicitation and/or exchange agent and outside counsel; provided, however, that nothing herein shall prohibit
KBR from engaging (at its own expense) its own financial, legal, accounting and other advisors in connection with such transfer or Distribution. 
 6.2 Cooperation for Halliburton Transfers. KBR agrees, at KBR’s sole expense, that it, and the members of the KBR Group, will use reasonable best efforts to assist Halliburton in any transfer of all or any portion of its KBR
Common Stock, whether in a public or private sale, exchange or other transaction to a Halliburton Transferee, including the execution and delivery of instruments of conveyance, assignment, assumption and delivery of stock certificates, stock powers
and other agreements or documents, in form and substance reasonably satisfactory to Halliburton, as shall be necessary to transfer such KBR Common Stock to the Halliburton Transferee and to vest in such Halliburton Transferee all related rights and
obligations as shall be assigned to it by Halliburton hereunder and under any Ancillary Agreement. The rights and obligations of the parties in this Section 6.2 are in addition to any rights and obligations set forth in any Ancillary Agreement.

 6.3 Cooperation for Halliburton Distribution. KBR agrees, at KBR’s sole expense, to take all actions requested by Halliburton
to facilitate a Distribution, including, without limitation, internal restructurings and continuation of businesses necessary to achieve such tax-free Distribution. KBR shall cooperate with Halliburton in all respects to accomplish any Distribution
and shall, at Halliburton’s direction, promptly take any and all actions necessary or desirable to effect such Distribution, including, without limitation, the following actions: 
 (a) Halliburton and KBR shall prepare, file with the Commission and mail, prior to the date of the Distribution to the holders of common
stock of Halliburton such information statement, registration statement or other information concerning KBR and the Distribution (and such other matters as Halliburton shall reasonably determine) as is necessary 

  

 40 

 
and as may be required by Law and applicable stock exchange requirement. Halliburton and KBR will prepare, and KBR will, to the extent required under
applicable Law, file with the Commission any such registration statement or other documentation which Halliburton and KBR determine is necessary or desirable to effectuate the Distribution, and Halliburton and KBR shall each use reasonable best
efforts to respond promptly to any comments of the Commission thereto and to obtain all necessary approvals from the Commission with respect thereto as soon as practicable. 
 (b) Halliburton and KBR shall take all such actions as may be necessary or appropriate under the securities or blue sky laws of the United
States (and any comparable laws under any foreign jurisdiction) in connection with the Distribution. 
 (c) KBR shall prepare
and file, and shall use its reasonable best efforts to have approved, an application for the listing of the KBR Common Stock to be distributed in the Distribution on the NYSE or such other exchange on which KBR Common Stock shall then be listed,
subject to official notice of distribution. 
 (d) Halliburton and KBR shall enter into a Distribution Agreement in form and
substance acceptable to Halliburton, a form of which is attached hereto as Schedule 6.3. 
 6.4 Registration Rights Agreement.
The Registration Rights Agreement sets forth the rights and obligations of the parties with respect to the registration and subsequent offering of shares of KBR Common Stock held by the Halliburton Group. 
 ARTICLE VII 
 ARBITRATION; DISPUTE RESOLUTION

 7.1 Agreement to Arbitrate. The procedures for discussion, negotiation and arbitration set forth in this Article VII shall be the
final, binding and exclusive means to resolve, and shall apply to all disputes, controversies or claims (whether in contract, tort or otherwise) that may rise out of or relate to, or arise under or in connection with: (a) this Agreement , any
Prior Transfer Agreement and/or any Ancillary Agreement, (b) the transactions contemplated hereby or thereby, including all actions taken in furtherance of the transactions contemplated hereby or thereby on or prior to the date hereof, or
(c) for a period of ten years after the IPO Closing Date, the commercial or economic relationship of the parties, in each case between or among any member of the Halliburton Group and the KBR Group. Each party agrees on behalf of itself and
each member of its respective Group that the procedures set forth in this Article VII shall be the final, binding and exclusive remedy in connection with any dispute, controversy or claim relating to any of the foregoing matters and irrevocably
waives any right to commence any Action in or before any Governmental Authority, except as expressly provided in Section 7.7(b) and except to the extent provided under the Federal Arbitration Act in the case of judicial review of arbitration
results or awards. Each party on behalf of itself and each member of its respective Group irrevocably waives any right to any trial by jury with respect to any dispute, controversy or claim covered by this Section 7.1. 
  

 41 

 7.2 Escalation. (a) It is the intent of the parties to use their respective reasonable best
efforts to resolve expeditiously any dispute, controversy or claim between or among them with respect to the matters covered by this Article VII pursuant to Section 7.1 that may arise from time to time on a mutually acceptable negotiated basis.
In furtherance of the foregoing, any party involved in a dispute, controversy or claim may deliver a notice (an “Escalation Notice”) demanding an in-person meeting involving representatives of the parties at a senior level of
management (or if the parties agree, of the appropriate business function or division within such entity) who have not previously been directly engaged in asserting or responding to the dispute. A copy of any such Escalation Notice shall be
delivered addressed to the General Counsel, or like chief legal officer or official, of each party involved in the dispute, controversy or claim (which copy shall state that it is an Escalation Notice pursuant to this Agreement). Any agenda,
location or procedures for such discussions or negotiations between the parties may be established by agreement of the parties from time to time; provided, however, that the parties shall use their reasonable best efforts to meet within 20 days of
the Escalation Notice. 
 (b) Following delivery of an Escalation Notice, the parties shall undertake good faith, diligent
efforts to negotiate a commercially reasonable resolution of the dispute, controversy or claim. The parties may, by mutual consent, retain a mediator to aid the parties in their discussions and negotiations by informally providing advice to parties.
Any opinion expressed by the mediator shall be strictly advisory and shall not be binding on the parties, nor shall any opinion expressed by the mediator be admissible in any arbitration proceedings. The mediator may be chosen from a list of
mediators previously selected by the parties or by other agreement of the parties. Costs of the mediation shall be borne equally by the parties involved in the matter, except that each party shall be responsible for its own expenses. Mediation is
not a prerequisite to an Arbitration Demand Notice under Section 7.3. 
 7.3 Demand for Arbitration. (a) At any time
following 60 days after the date of an Escalation Notice (the “Arbitration Demand Date”), any party involved in the dispute, controversy or claim (regardless of whether such party delivered the Escalation Notice) may deliver a
notice demanding arbitration of such dispute, controversy or claim (an “Arbitration Demand Notice”). Delivery of an Escalation Notice by a party shall be a prerequisite to delivery of an Arbitration Demand Notice by either party,
provided, however, that in the event that any party shall deliver an Arbitration Demand Notice to another party, such other party may itself deliver an Arbitration Demand Notice to such first party with respect to any related dispute, controversy or
claim with respect to which the Applicable Deadline has not passed without the requirement of delivering an Escalation Notice. No party may assert that the failure to resolve any matter during any prior discussions or negotiations, the course of
conduct during such prior discussions or negotiations, or the failure to agree on a mutually acceptable time, agenda, location or procedures for a meeting is a prerequisite to an Arbitration Demand Notice under Section 7.3. In the event that
any party delivers an Arbitration Demand Notice with respect to any dispute, controversy or claim that is the subject of any then pending arbitration proceeding or of a previously delivered Arbitration Demand Notice, all such disputes, controversies
and claims shall be resolved in the arbitration proceeding for which an Arbitration Demand Notice was first delivered unless the arbitrators in their sole discretion determine that it is impracticable or otherwise inadvisable to do so. 

 

 42 

 (b) Except as may be expressly provided in any Ancillary Agreement or Prior Transfer
Agreement, any Arbitration Demand Notice may be given until the date that is two years after the later of the occurrence of the act or event giving rise to the underlying claim or the date on which such act or event was, or should have been, in the
exercise of reasonable due diligence, discovered by the party asserting the claim (as applicable and as it may in a particular case be specifically extended by the parties in writing, the “Applicable Deadline”). Any discussions,
negotiations or mediations between the parties pursuant to this Agreement or otherwise will not toll the Applicable Deadline unless expressly agreed in writing by the parties. Each of the parties agrees on behalf of itself and each member of its
Group that if an Arbitration Demand Notice with respect to a dispute, controversy or claim is not given prior to the expiration of the Applicable Deadline, as between or among the parties and the members of their Groups, such dispute, controversy or
claim will be barred. Subject to Section 7.7(b) and Section 7.9, upon delivery of an Arbitration Demand Notice pursuant to Section 7.3(a) prior to the Applicable Deadline, the dispute, controversy or claim, and all substantive and
procedural issues related thereto, shall be decided by a three member panel of arbitrators in accordance with this Article VII. 
 7.4
Arbitrators. (a) The party delivering the Arbitration Demand Notice shall notify the American Arbitration Association (“AAA”) and the other parties in writing describing in reasonable detail the nature of the dispute.
Within 20 days of the date of the Arbitration Demand Notice, each party to the dispute shall select one arbitrator from the members of a panel of arbitrators of the AAA. The selected arbitrators shall then jointly select a third arbitrator from the
members of a panel of arbitrators of the AAA, and such third arbitrator shall be disinterested with respect to each of the parties and shall be experienced in complex commercial arbitration. In the event that the parties’ selected arbitrators
are unable to agree on the selection of the third arbitrator, the AAA shall select the third arbitrator, within 45 days of the date of the Arbitration Demand Notice. In the event that any arbitrator is unable to serve, his replacement will be
selected in the same manner as the arbitrator to be replaced. The vote of two of the three arbitrators shall be required for any decision under this Article VII. 
 (b) The arbitrators will set a time for the hearing of the matter which will commence no later than 180 days after the date of appointment
of the third arbitrator and which hearing will be no longer than 30 days (unless in the judgment of the arbitrators the matter is unusually complex and sophisticated and thereby requires a longer time, in which event such hearing shall be no longer
than 90 days). The final decision of such arbitrators will be rendered in writing to the parties not later than 60 days after the last day of the hearing, unless otherwise agreed by the parties in writing. 
 (c) The place of any arbitration hereunder will be Houston, Texas and the language of any arbitration hereunder will be English, unless
otherwise agreed by the parties. Unless otherwise agreed by the parties, the arbitration hearing shall be conducted on consecutive days. 
 7.5 Hearings. Within the time period specified in Section 7.4(b), the matter shall be presented to the arbitrators at a hearing by means of written submissions of memoranda and verified witness statements, filed simultaneously,
and responses, if necessary in the judgment of the arbitrators or both of the parties. If the arbitrators deem it to be essential to a fair resolution 

  

 43 

 
of the dispute, live cross-examination or direct examination may be permitted, but is not generally contemplated to be necessary. The arbitrators shall
actively manage the arbitration with a view to achieving a just, speedy and cost-effective resolution of the dispute, claim or controversy. The arbitrators may, in their discretion, set time and other limits on the presentation of each party’s
case, its memoranda or other submissions, and may refuse to receive any proffered evidence, which the arbitrators, in their discretion, find to be cumulative, unnecessary, irrelevant or of low probative nature. Any arbitration hereunder shall be
conducted in accordance with the Commercial Arbitration Rules of the AAA in effect on the date the notice of Arbitration Demand Notice is served. The decision of the arbitrators will be final and binding on the parties, and judgment thereon may be
had and will be enforceable in any court having jurisdiction over the parties. Arbitration awards will bear interest at an annual rate of the then-prevailing prime rate plus 2% per annum, subject to any maximum amount permitted by applicable
law. To the extent that the provisions of this Agreement and the prevailing rules of the AAA conflict, the provisions of this Agreement shall govern. 
 7.6 Discovery and Certain Other Matters. (a) Any party involved in a dispute, controversy or claim subject to this Article VII may request document production from the other party or parties of specific
and expressly relevant documents, with the reasonable expenses of the producing party incurred in such production paid by the requesting party. Any such discovery shall be conducted in accordance with the International Bar Association Rules on the
Taking of Evidence in International Commercial Arbitration, subject to the discretion of the arbitrators. Any such discovery shall be conducted expeditiously and shall not cause the hearing to be adjourned except upon consent of all parties involved
in the applicable dispute or upon an extraordinary showing of cause demonstrating that such adjournment is necessary to permit discovery essential to a party to the proceeding. Disputes concerning the scope of document production and enforcement of
the document production requests will be determined by written agreement of the parties involved in the applicable dispute or, failing such agreement, will be referred to the arbitrators for resolution. All discovery requests will be subject to the
parties’ rights to claim any applicable privilege. The arbitrators will adopt procedures to protect the proprietary rights of the parties and to maintain the confidential treatment of the arbitration proceedings (except as may be required by
law). Subject to the foregoing, the arbitrators shall have the power to issue subpoenas to compel the production of documents relevant to the dispute, controversy or claim. 
 (b) The arbitrators shall have full power and authority to determine issues of arbitrability but shall otherwise be limited to
interpreting or construing the applicable provisions of this Agreement, any Ancillary Agreement or any Prior Transfer Agreement, and will have no authority or power to limit, expand, alter, amend, modify, revoke or suspend any condition or provision
of this Agreement, any Ancillary Agreement or any Prior Transfer Agreement; it being understood, however, that the arbitrators will have full authority to implement the provisions of this Agreement, any Ancillary Agreement or any Prior Transfer
Agreement, and to fashion appropriate remedies for breaches of this Agreement (including interim or permanent injunctive relief); provided that the arbitrators shall not have (i) any authority in excess of the authority a court having
jurisdiction over the parties and the controversy or dispute would have absent these arbitration provisions or (ii) any right or power to award punitive or treble damages. It is the intention of the parties that in rendering a decision the
arbitrators give effect to the applicable provisions of this Agreement, the Ancillary Agreements and the Prior Transfer Agreements and 

  

 44 

 
follow applicable law (it being understood and agreed that this sentence shall not give rise to a right of judicial review of the arbitrators’ award).

 (c) If a party fails or refuses to appear at and participate in an arbitration hearing after due notice, the arbitrators
may hear and determine the controversy upon evidence produced by the appearing party. 
 (d) Arbitration costs will be borne
equally by each party involved in the matter, and each party will be responsible for its own attorneys’ fees and other costs and expenses, including the costs of witnesses selected by such party. 
 7.7 Certain Additional Matters. (a) Any arbitration award shall be a bare award limited to a holding for or against a party and shall be
without findings as to facts, issues or conclusions of law (including with respect to any matters relating to the validity or infringement of patents or patent applications) and shall be without a statement of the reasoning on which the award rests,
but must be in adequate form so that a judgment of a court may be entered thereupon. Judgment upon any arbitration award hereunder may be entered in any court having jurisdiction thereof. 
 (b) Prior to the time at which all of the arbitrators have been appointed pursuant to Section 7.4, any party may seek one or more
temporary restraining orders in a court of competent jurisdiction if necessary in order to preserve and protect the status quo. Neither the request for, nor grant or denial of, any such temporary restraining order shall be deemed a waiver of the
obligation to arbitrate as set forth herein and the arbitrators may dissolve, continue or modify any such order. Any such temporary restraining order shall remain in effect until the first to occur of the expiration of the order in accordance with
its terms or the dissolution thereof by the arbitrators. 
 (c) Except as required by law, the parties shall hold, and shall
cause their respective officers, directors, employees, agents and other representatives to hold, the existence, content and result of mediation or arbitration in confidence in accordance with the provisions of Section 8.11 and except as may be
required in order to enforce any award. Each of the parties shall request that any mediator or arbitrator comply with such confidentiality requirement. 
 7.8 Continuity of Service and Performance. Unless otherwise agreed in writing, the parties will continue to provide service and honor all other commitments under this Agreement, each Ancillary Agreement, each
Prior Transfer Agreement and any other agreement between or among any members of the Halliburton Group and the KBR Group during the course of the dispute resolution procedures pursuant to this Article VII with respect to all matters not subject to
such dispute, controversy or claim. 
 7.9 Law Governing Arbitration Procedures. The interpretation of the provisions of this Article
VII, only insofar as they relate to the agreement to arbitrate and any procedures pursuant thereto, shall be governed by the Federal Arbitration Act, as amended, and other applicable federal law. In all other respects, the interpretation of this
Agreement shall be governed as set forth in Section 9.3. 
  

 45 

 ARTICLE VIII 
 COVENANTS AND OTHER MATTERS 
 8.1 Other Agreements. In addition to the specific agreements, documents
and instruments contemplated by this Agreement, Halliburton and KBR agree to execute or cause to be executed by the appropriate parties and deliver, as appropriate, such other agreements, instruments and other documents as may be necessary or
desirable in order to effect the purposes of this Agreement and the Ancillary Agreements. 
 8.2 Further Instruments. The parties
intend to separate the KBR Business from the Halliburton Business hereby, and to convey, assign or otherwise transfer to the KBR Group the assets, rights and other items relating to the KBR Business, and to convey, assign or otherwise transfer to
the Halliburton Group the assets, rights and other items relating to the Halliburton Business. At the request of either Halliburton or KBR following the Separation Date, and without further consideration, the other party will execute and deliver,
and will cause the applicable members of its Group to execute and deliver, to the requesting party and the applicable members of its Group such other instruments of transfer, conveyance, assignment, substitution and confirmation and take such action
as the requesting party may reasonably deem necessary or desirable in order more effectively to transfer, convey and assign to the requesting party and the members of its Group and confirm the requesting party’s and the members of its
Group’s title to all of the assets, rights and other items contemplated to be transferred to the requesting party and the members of its Group pursuant to a Prior Transfer Agreement, this Agreement, the Ancillary Agreements, and any documents
referred to therein, to put the requesting party and the members of its Group in actual possession and operating control thereof and to permit the requesting party and the members of its Group to exercise all rights with respect thereto (including,
without limitation, rights under contracts and other arrangements as to which the consent of any third party to the transfer thereof shall not have previously been obtained). At the request of either Halliburton or KBR following the Separation Date,
and without further consideration, the other party will execute and deliver, and will cause the applicable members of its Group to execute and deliver, to the requesting party and the applicable members of its Group all instruments, assumptions,
novations, undertakings, substitutions or other documents and take such other action as the requesting party may reasonably deem necessary or desirable in order to have the other party fully and unconditionally assume and discharge the Liabilities
contemplated to be assumed by the other party under a Prior Transfer Agreement, this Agreement, any Ancillary Agreement or any document in connection herewith and to relieve the Halliburton Group or the KBR Group, as applicable, of any liability or
obligation with respect thereto and evidence the same to third parties. Neither the requesting party nor the other party shall be obligated, in connection with the foregoing, to expend money other than reasonable out-of-pocket expenses,
attorneys’ fees and recording or similar fees. Furthermore, each party, at the request of another party hereto, shall execute and deliver such other instruments and do and perform such other acts and things as may be necessary or desirable for
effecting completely the consummation of the transactions contemplated hereby. 
 8.3 Provision of Corporate Records. Except as
contemplated by Sections 3.4 and 3.5, as soon as practicable after the Separation Date, subject to the provisions of this Section 8.3 and the provisions of Section 6.2 of the Transition Services Agreements, Halliburton shall use 

  

 46 

 
reasonable best efforts to deliver or cause to be delivered to KBR all KBR Books and Records in the possession of Halliburton or any member of the
Halliburton Group, and KBR shall use reasonable best efforts to deliver or cause to be delivered to Halliburton all Halliburton Books and Records in the possession of KBR or any member of the KBR Group. The foregoing shall be limited by the
following: 
 (a) To the extent any document (including computer files, as applicable) can be subdivided without unreasonable
effort or cost into two portions, one of which constitutes a KBR Book and Record and the other of which constitutes a Halliburton Book and Record, such document (including computer files, as applicable) shall be so subdivided and the appropriate
portions shall be delivered to the parties. 
 (b) In the case of this Section 8.3, “reasonable best efforts”
shall require only deliveries of (i) specific and discrete books and records or a reasonably limited class of items requested by the other party and (ii) specific and discrete books and records identified by either party in the ordinary
course of business and determined by such party to be material to the other’s business. 
 (c) Each party may retain
copies of books and records delivered to the other, subject to holding in confidence in accordance with Section 8.11 information contained in such books and records. 
 (d) Each party may in good faith refuse to furnish any books and records under this Section 8.3 if it reasonably believes in good
faith that doing so could materially adversely affect its ability to successfully assert a claim of Privilege. 
 (e) Neither
party shall be required to deliver to the other books and records or portions thereof which are subject to any Law or confidentiality agreements which would by their terms prohibit such delivery; provided, however, that if requested by the other
party, such party shall use reasonable best efforts to seek a waiver of or other relief from such confidentiality restriction. 
 (f) Nothing in this Section 8.3 shall affect the rights and obligations of any party to the Tax Sharing Agreement with respect to the sharing of information related to Taxes. 
 8.4 Agreement For Exchange of Information. 
 (a) Each of Halliburton and KBR agrees to provide, or cause to be provided, to each other as soon as reasonably practicable after written request therefor, any Information in the possession or under the control of
such party that the requesting party reasonably needs: (i) to comply with reporting, disclosure, filing or other requirements imposed on the requesting party (including under applicable securities laws) by a Governmental Authority having
jurisdiction over the requesting party, (ii) for use in any Regulatory Proceeding, judicial proceeding or other proceeding or in order to satisfy audit, accounting, claims, regulatory, litigation, subpoena or other similar requirements,
(iii) to comply with its obligations under this Agreement or any Ancillary Agreement or (iv) in connection with its ongoing businesses as it relates to the conduct of such business, as the case may be; provided, however, that in the event
that any party determines that any such provision of Information could be commercially 

  

 47 

 
detrimental, violate any Law or agreement, or waive any attorney-client privilege, the parties shall take all reasonable measures to permit the compliance
with such obligations in a manner that avoids any such harm or consequence. 
 (b) After the Separation Date, notwithstanding
the parties’ rights and obligations in Section 8.5 hereof, (i) each party shall maintain in effect at its own cost and expense adequate systems and controls for its business to the extent necessary to enable the other party to satisfy
its reporting, accounting, audit and other obligations in compliance with all applicable Law and stock exchange requirements, and (ii) each party shall provide, or cause to be provided, to the other party and the applicable members of its Group
in such form as such requesting party shall request, at no charge to the requesting party, all financial and other data and information as the requesting party determines necessary or advisable in order to prepare its financial statements and
reports or filings with any Governmental Authority. 
 (c) Any Information owned by a party that is provided to a requesting
party pursuant to this Section 8.4 shall be deemed to remain the property of the providing party. Unless specifically set forth herein, nothing contained in this Agreement shall be construed as granting or conferring rights of license or
otherwise in any such Information. 
 (d) To facilitate the possible exchange of Information pursuant to this Section 8.4
and other provisions of this Agreement, each party agrees to use reasonable best efforts to retain all Information in its respective possession or control substantially in accordance with its record retention policies as in effect on the Separation
Date. For so long as the Halliburton Group collectively beneficially owns shares of KBR Common Stock representing at least 15% or more of the total voting power of all of the outstanding shares of KBR Voting Stock, KBR shall not amend its or any
member of its Group’s record retention policies without the consent of Halliburton. However, except as set forth in the Tax Sharing Agreement, at any time after the date that the Halliburton Group collectively beneficially owns shares of KBR
Common Stock representing less than 15% of the total voting power of all of the outstanding shares of KBR Voting Stock, KBR may amend its record retention policies at KBR’s discretion; provided, however, that KBR must give Halliburton thirty
(30) days prior written notice of such change in the policy. No party will destroy, or permit any member of its Group to destroy, any Information that exists on the Separation Date (other than Information that is permitted to be destroyed under
the Halliburton record retention policy in effect as of the date hereof) without first using its reasonable best efforts to notify the other party of the proposed destruction and giving the other party the opportunity to take possession of such
Information prior to such destruction. 
 (e) No party shall have any liability to any other party in the event that any
Information exchanged or provided pursuant to this Section 8.4 is found to be inaccurate, in the absence of willful misconduct by the party providing such Information. No party shall have any duty to update any Information exchanged or provided
pursuant to this Section 8.4. No party shall have any liability to any other party if any Information is destroyed or lost after reasonable best efforts by such party to comply with the provisions of Section 8.4(d). 
 (f) The rights and obligations granted under this Section 8.4 are subject to any specific limitations, qualifications or additional
provisions on the sharing, exchange or 

  

 48 

 
confidential treatment of Information set forth in Sections 3.4 and 3.5 of this Agreement and any Ancillary Agreement. 
 (g) Each party hereto shall, except in the case of a dispute subject to Article VII brought by one party against another party (which
shall be governed by such discovery rules as may be applicable under Article VII or otherwise), use reasonable best efforts to make available to each other party, upon written request, the former, current and future directors, officers, employees,
other personnel and agents of such party as witnesses and any books, records or other documents within its control or which it otherwise has the ability to make available, to the extent that any such person (giving consideration to business demands
of such directors, officers, employees, other personnel and agents) or books, records or other documents may reasonably be required by the other party in connection with any Regulatory Proceeding, judicial proceeding or other proceeding in which the
requesting party may from time to time be involved, regardless of whether such Regulatory Proceeding, judicial proceeding or other proceeding is a matter with respect to which indemnification may be sought hereunder. The requesting party shall bear
all costs and expenses in connection therewith; provided that witnesses shall be made available under this Section 8.4(g) without cost other than reimbursement of actual out-of-pocket expenses and reasonable attorneys’ fees and expenses
incurred. 
 8.5 Auditors and Audits; Annual and Quarterly Statements and Accounting. (a) Each party agrees that, for so long as
the Halliburton Group beneficially owns shares of KBR Common Stock representing 15% or more of the total voting power of all of the outstanding shares of KBR Voting Stock, and with respect to any financial reporting period during which the
Halliburton Group collectively beneficially owns shares of KBR Common Stock representing 15% or more of the total voting power of all of the outstanding shares of KBR Voting Stock: 
 (i) Selection of Auditor. KBR shall not select a different accounting firm than the firm selected by Halliburton to audit its
financial statements to serve as its independent certified public accountants for purposes of providing an opinion on its consolidated financial statements without Halliburton’s prior written consent (which shall not be unreasonably withheld).
At all times, KBR shall retain a nationally recognized accounting firm to serve as its independent certified public accountants for purposes of providing an opinion on KBR’s consolidated financial statements (the “KBR
Auditors”). 
 (ii) Annual and Quarterly Reviews. KBR shall use reasonable best efforts to enable the KBR
Auditors to complete their audit such that they will date their opinion on KBR’s audited annual financial statements on the same date that Halliburton’s Auditors date their opinion on Halliburton’s audited annual financial statements,
and to enable Halliburton to meet its timetable for the printing, filing and public dissemination of Halliburton’s annual financial statements, including press releases relating to earnings information. KBR shall use reasonable best efforts to
enable the KBR Auditors to complete their quarterly review procedures such that they will provide clearance on KBR’s quarterly financial statements on the same date that Halliburton’s Auditors provide 

  

 49 

 
clearance on Halliburton’s quarterly financial statements, and to enable Halliburton to meet its timetable for the printing, filing and public
dissemination of Halliburton’s quarterly financial statements, including press releases relating to earnings information. 
 (iii) Information for Preparation of Financial Statements. KBR shall provide to Halliburton on a timely basis all Information that Halliburton reasonably requires to meet its schedule for the preparation, printing, filing and public
dissemination of Halliburton’s annual, quarterly and periodic financial statements, including press releases relating to earnings information. Without limiting the generality of the foregoing, KBR will provide all required financial information
with respect to the KBR Group to the KBR Auditors in a sufficient and reasonable time and in sufficient detail to permit the KBR Auditors to take all steps and perform all reviews necessary to provide sufficient assurance to Halliburton’s
Auditors with respect to Information to be included or contained in Halliburton’s annual, quarterly and periodic financial statements, including press releases relating to earnings information. Similarly, Halliburton shall provide to KBR on a
timely basis all Information that KBR reasonably requires to meet its schedule for the preparation, printing, filing and public dissemination of KBR’s annual, quarterly and periodic financial statements, including press releases relating to
earnings information. Without limiting the generality of the foregoing, Halliburton will provide all required financial Information with respect to the Halliburton Group to Halliburton’s Auditors in a sufficient and reasonable time and in
sufficient detail to permit Halliburton’s Auditors to take all steps and perform all reviews necessary to provide sufficient assurance to the KBR Auditors with respect to Information to be included or contained in KBR’s annual, quarterly
and periodic financial statements, including press releases relating to earnings information. 
 (iv) Access to Auditors
and Work Papers. KBR shall authorize the KBR Auditors to make available to Halliburton’s Auditors both the personnel who performed or are performing the annual audits and quarterly reviews of KBR and work papers related to such reviews of
KBR, in all cases within a reasonable time prior to the KBR Auditors’ opinion date, so that Halliburton’s Auditors are able to perform the procedures they consider necessary to take responsibility for the work of the KBR Auditors as it
relates to Halliburton’s Auditors’ report on Halliburton’s financial statements, all within sufficient time to enable Halliburton to meet its timetable for the printing, filing and public dissemination of Halliburton’s annual and
quarterly financial statements, including press releases relating to earnings information. Similarly, Halliburton shall authorize Halliburton’s Auditors to make available to the KBR Auditors both the personnel who performed or are performing
the annual audits and quarterly reviews of Halliburton and work papers related to such reviews of Halliburton, in all cases within a reasonable time prior to Halliburton’s Auditors’ opinion date, so that the KBR Auditors are able to
perform the procedures they consider necessary to take responsibility for the work of Halliburton’s Auditors as it relates to the KBR Auditors’ report on KBR’s financial statements, all within sufficient time to 

  

 50 

 
enable KBR to meet its timetable for the printing, filing and public dissemination of KBR’s annual and quarterly financial statements, including press
releases relating to earnings information. 
 (v) Accounting Principles and Practices. Without the prior written
consent of Halliburton, KBR may not change its accounting principles or practices if a change in such accounting principle or practice would be required to be disclosed in KBR’s financial statements as filed with the SEC or otherwise publicly
disclosed, except for such changes which are required by GAAP and as to which there is no discretion on the part of KBR, as concurred in by the KBR Auditors prior to its implementation. KBR shall give Halliburton as much prior notice as reasonably
practical of any proposed determination of, or any significant changes in, its accounting estimates or, subject as aforesaid, accounting principles from those in effect on the Separation Date. KBR will consult with Halliburton and, if requested by
Halliburton, KBR will consult with Halliburton’s Auditors with respect thereto. Halliburton shall give KBR as much prior notice as reasonably practical of any proposed determination of, or any significant changes in, its accounting estimates or
accounting principles pertaining to KBR from those in effect on the Separation Date. 
 (vi) Comfort Letters. Upon
Halliburton’s request, KBR shall use reasonable best efforts to cause to be delivered “comfort letters” of the KBR Auditors with regard to KBR’s financial statements, dated as of the pricing dates and the closing dates and
addressed to the underwriters, in any offering of securities by Halliburton or any member of the Halliburton Group for which such comfort letters are required by underwriters. Such “comfort letters” shall be in form reasonably satisfactory
to Halliburton and customary in scope and substance for “comfort letters” delivered by independent public accountants in connection with public securities offerings. 
 (vii) Auditor Consents. KBR shall use reasonable best efforts to cause the KBR Auditors to consent to inclusion of the information
described in this Section 8.5 and to be named in Halliburton’s filings with the Commission with respect to any such information as is customary for such consents. 
 (b) Provision of Financial Information. For so long as the Halliburton Group collectively beneficially owns 15% or more of the
total voting power of all of the outstanding shares of KBR Voting Stock: (i) KBR will furnish Halliburton within ten (10) Business Days after the end of each quarter and ten (10) Business Days after the end of each fiscal year, the

 (c) Assignment to Halliburton Transferee. Halliburton may transfer all or any
portion of its rights under this Section 8.5 to a Halliburton Transferee holding at least 15% of the voting power of all of the outstanding KBR Common Stock. Halliburton shall give written notice to KBR of its transfer of rights under this
Section 8.5 no later than 30 days after Halliburton enters into a binding agreement for such transfer of rights. Such notice shall state the name and address of the Halliburton Transferee and identify the amount of KBR Common Stock transferred
and the scope of rights being transferred under this Section 8.5. In connection with any such transfer, the term “Halliburton” as used in this Section 8.5 shall, where appropriate to give effect to the assignment of rights and
obligations hereunder to such Halliburton Transferee, be deemed to refer to such Halliburton Transferee. Halliburton and any Halliburton Transferee may exercise the rights under this Section 8.5 in such priority, as among themselves, as they
shall agree upon among themselves, and KBR shall observe any such agreement of which it shall have notice as provided above. 
 8.6 Audit
Rights. To the extent any member of the Halliburton Group provides goods or services to any member of the KBR Group, or any member of the KBR Group provides goods or services to a member of the Halliburton Group, under this Agreement or under
any Ancillary Agreement (other than pursuant to the Transition Services Agreements), the company providing such goods or services (the “Providing Company”) shall maintain complete and accurate books and records relating to costs and
charges made to the company receiving such goods and services (the “Receiving Company”). Books and accounts shall be maintained in accordance with generally accepted accounting principles, consistently applied. Annually, the
Receiving Company, at its expense, shall be entitled to audit the Providing Company’s books and records related to the goods and services provided during the preceding year, using its own personnel or personnel from its independent auditing
firm. Discrepancies identified as a result of any audit shall be promptly reconciled and agreed between the parties or, if no such reconciliation is agreed by the parties, shall be resolved in accordance with the dispute resolution provisions of
Article VII of this Agreement. Any charge which is not questioned by the Receiving Company within the calendar year after the calendar year in which the charge was rendered shall be deemed incontestable. 
 8.7 Preservation of Legal Privileges. (a) Halliburton and KBR recognize that the members of their respective groups possess and will possess
information and advice that has been previously developed but is legally protected from disclosure under legal privileges, such as the attorney-client privilege or work product exemption and other concepts of legal protection
(“Privilege”). Each party recognizes that they shall be jointly entitled to the Privilege with respect to such privileged information and that each shall be entitled to maintain, preserve and assert for its own benefit all such
information and advice, but both parties shall ensure that such information is maintained so as to protect the Privileges with respect to the other party’s interest. To that end, neither party will knowingly waive or compromise any Privilege
associated with such information and advice without the prior written consent of the other party. In the event that privileged information is required to be disclosed to any arbitrator or mediator in connection with a dispute between the parties,
such disclosure shall not be deemed a waiver of Privilege with respect to such information, and any party receiving it in connection with a proceeding shall be informed of its nature and shall be required to safeguard and protect it. 
  

 52 

 (b) The rights and obligations created by this Section 8.7 shall apply to all
information relating to the KBR Business as to which, but for the Separation, either party would have been entitled to assert or did assert the protection of a Privilege, including (i) any and all information generated prior to the Separation
Date but which, after the Separation, is in the possession of either party and (ii) all information generated, received or arising after the Separation Date that refers to or relates to information described in the preceding clause (i).

 (c) Upon receipt by either party of any subpoena, discovery or other request that may call for the production or disclosure
of information that is the subject of a Privilege, or if a party obtains knowledge that any current or former employee of a party has received any subpoena, discovery or other request that may call for the production or disclosure of such
information, such party shall provide the other party a reasonable opportunity to review the information and to assert any rights it may have under this Section 8.7 or otherwise to prevent the production or disclosure of such information.
Absent receipt of written consent from the other party to the production or disclosure of information that may be covered by a Privilege, each party agrees that it will not produce or disclose any information that may be covered by a Privilege
unless a court of competent jurisdiction has entered a final, nonappealable order finding that the information is not entitled to protection under any applicable Privilege. 
 (d) Nothing in this Section 8.7 shall limit or qualify the rights and obligations of the parties in Section 3.4(d),
Section 3.5(d) and Section 8.15. 
 8.8 Payment of Expenses. KBR shall pay all underwriting fees, discounts and commissions
and other direct costs incurred in connection with the IPO. Except as otherwise provided in this Agreement, the Ancillary Agreements or any other agreement between the parties relating to the Separation, the IPO or the Distribution, all other
out-of-pocket costs and expenses of the parties hereto in connection with the preparation of this Agreement and the Ancillary Agreements, the Separation, the IPO and the Distribution shall be paid by Halliburton. Notwithstanding the foregoing, KBR
shall pay any internal fees, costs and expenses incurred by KBR in connection with the Separation, the IPO and the Distribution. 
 8.9
Governmental Approvals. The parties acknowledge that certain of the transactions contemplated by this Agreement and the Ancillary Agreements may be subject to certain conditions established by applicable government regulations, orders, and
approvals (“Existing Authority”). The parties intend to implement this Agreement, the Ancillary Agreements and the transactions contemplated hereby and thereby consistent with and to the extent permitted by Existing Authority and to
cooperate toward obtaining and maintaining in effect such Governmental Approvals as may be required in order to implement this Agreement and each of the Ancillary Agreements as fully as possible in accordance with their respective terms. To the
extent that any of the transactions contemplated by this Agreement or any Ancillary Agreement require any Governmental Approvals, the parties will use their reasonable best efforts to obtain any such Governmental Approvals. 
 8.10 Continuance of Halliburton Credit Support. (a) Duration of Existing Credit Support Agreements. Notwithstanding any other
provision of this Agreement or any Ancillary Agreement to the contrary, and except as set forth in Section 8.10(b) below, the parties hereby agree that Halliburton and each applicable member of the Halliburton Group shall maintain in 

  

 53 

 
full force and effect each Credit Support Agreement which is issued and outstanding as of the Separation Date until the earlier of: (i) such time as the
project contract, or all obligations of any member of the KBR Group thereunder, to which such Credit Support Agreement relates terminates or (ii) such time as such Credit Support Agreement or the underlying instrument to which it relates

 8.11 Confidentiality. 
 (a) Until the date that is five (5) years from the date hereof, Halliburton and KBR shall hold and shall cause the members of the Halliburton Group and the KBR Group, respectively, to hold, and shall each cause
their respective officers, employees, agents, consultants and advisors to hold, in strict confidence and not to disclose or release without the prior written consent of the other party, any and all Confidential Information (as defined herein);
provided, that the parties may disclose, or may permit disclosure of, Confidential Information: (i) to their respective auditors, attorneys, financial advisors, bankers and other appropriate consultants and advisors who have a need to know such
information and are informed of their obligation to hold such information confidential to the same extent as is applicable to the parties hereto and in respect of whose failure to comply with such obligations, Halliburton or KBR, as the case may be,
will be responsible or (ii) to the extent any member of the Halliburton Group or the KBR Group is compelled to disclose any such Confidential Information by judicial or administrative process or, in the opinion of legal counsel, by other
requirements of Law. Notwithstanding the foregoing, in the event that any demand or request for disclosure of Confidential Information is made pursuant to clause (ii) above, Halliburton or KBR, as the case may be, shall promptly notify the
other of the existence of such request or demand and shall provide the other a reasonable opportunity to seek an appropriate protective order or other remedy, which both parties will cooperate in seeking to obtain. In the event that such appropriate
protective order or other remedy is not obtained, the party being compelled to disclose the Confidential Information shall furnish or cause to be furnished only that portion of the Confidential Information that is legally required to be disclosed.
As used in this Section 8.11, “Confidential Information” shall mean all proprietary, technical or operational information, data or material of one party which, prior to or following the Separation Date, has been disclosed by
Halliburton or members of the Halliburton Group, on the one hand, or KBR or members of the KBR Group, on the other hand, in written, oral (including by recording), electronic, or visual form to, or otherwise has come into the possession of, the
other, including pursuant to any provision of this Agreement (except to the extent that such Confidential Information can be shown to have been (a) in the public domain through no fault of such party or (b) later lawfully acquired from
other sources by the party to which it was furnished; provided, however, in the 

  

 56 

 
case of (b) that such sources did not provide such Confidential Information in breach of any confidentiality obligations). 
 (b) Notwithstanding anything to the contrary set forth herein, (i) Halliburton and the other members of the Halliburton Group, on the
one hand, and KBR and the other members of the KBR Group, on the other hand, shall be deemed to have satisfied their obligations hereunder with respect to Confidential Information if they exercise the same degree of care (but no less than a
reasonable degree of care) as they take to preserve confidentiality for their own similar Information and (ii) confidentiality obligations provided for in any agreement between Halliburton or any other member of the Halliburton Group, or KBR or
any other members of the KBR Group, on the one hand, and any employee of Halliburton or any other member of the Halliburton Group, or KBR or any other members of the KBR Group, on the other hand, shall remain in full force and effect. Confidential
Information of Halliburton or any other member of the Halliburton Group, on the one hand, or KBR or any other member of the KBR Group, on the other hand, in the possession of and used by the other as of the Separation Date may continue to be used by
such Person in possession of the Confidential Information in and only in the operation of the Halliburton Business or the KBR Business, as the case may be, and may be used only so long as the Confidential Information is maintained in confidence and
not disclosed in violation of Section 8.11(a). Such continued right to use may not be transferred to any third party unless the third party purchases all or substantially all of the business and assets in which the relevant Confidential
Information is used or employed in one transaction or in a series or related transactions. In the event that such right to use is transferred in accordance with the preceding sentence, the transferring party shall not disclose the source of the
relevant Confidential Information. 
 (c) Nothing in this Section 8.11 shall limit or qualify the rights and obligations
of the parties with respect to Sections 3.4 and 3.5 hereof. 
 (d) Nothing in Sections 8.3, 8.4 or 8.5 shall require KBR to
violate any agreement with any third parties regarding the confidentiality of confidential and proprietary information relating to that third party or its business; provided, however, that in the event that KBR is required under Sections 8.3, 8.4 or
8.5 to disclose any such information, KBR shall use reasonable best efforts to seek to obtain such third party’s consent to the disclosure of such information. Similarly, nothing in Sections 8.3, 8.4 or 8.5 shall require Halliburton to violate
any agreement with any third parties regarding the confidentiality of confidential and proprietary information relating to that third party or its business; provided, however, that in the event that Halliburton is required under Sections 8.3, 8.4 or
8.5 to disclose any such information, Halliburton shall use reasonable best efforts to seek to obtain such third party’s consent to the disclosure of such information. 
 (e) Nothing in this Section 8.11 shall limit or qualify the rights and obligations of the parties under the Intellectual Property
Matters Agreement. 
 8.12 Receipt of Notices. If a party receives a notice or other communication from any Governmental Authority or
third party, or otherwise becomes aware of any fact or circumstance after the Separation Date relating to an asset, contract or ownership interest transferred to the other party or liability assumed by the other party, it will promptly forward the
notice or other 

  

 57 

 
communication to the other party or give notice to the other party of such fact or circumstance of which it has become aware. Each of Halliburton and KBR
will comply, and will cause members of their respective Groups to comply, with this Section 8.12. 
 8.13 Non Solicitation of

KBR or a member of the KBR Group immediately after the Separation Date or (ii) solicit or encourage any current employee or independent contractor of the KBR Group who has worked full-time for the KBR Business to leave the employment of KBR or
a member of the KBR Group. Nothing in this Section 8.13 shall prevent or restrict Halliburton or any member of the Halliburton Group from employing any individual who responds to a general solicitation for employment made by or on behalf of
Halliburton or any member of the Halliburton Group that is not specifically directed at employees, independent contractors or officers of KBR who have worked in the KBR Business or any individual who, after the Separation Date, initiates contact
with Halliburton or any member of the Halliburton Group for purposes of seeking employment. 
 (b) KBR No Hire. For a
period of one (1) year from the Separation Date, KBR agrees not to (i) solicit, recruit or hire any employees, independent contractors or officers of the Halliburton Group who have worked for or been contracted to the Halliburton Business

Halliburton Group who has worked full-time for the Halliburton Business to leave the employment of Halliburton or a member of the Halliburton Group. Nothing in this Section 8.13 shall prevent or restrict KBR or any member of the KBR Group from
employing any individual who responds to a general solicitation for employment made by or on behalf of KBR or any member of the KBR Group that is not specifically directed at employees, independent contractors or officers of Halliburton who have
worked in the Halliburton Business or any individual who, after the Separation Date, initiates contact with KBR or any member of the KBR Group for purposes of seeking employment. 
 8.14 Halliburton Policies and Procedures. (a) For so long as the Halliburton Group beneficially owns shares of KBR Common Stock representing
a majority of the total voting power of all of the outstanding shares of KBR Voting Stock, the KBR Group will consistently implement and maintain Halliburton’s business practices and standards with respect to internal controls and the
Halliburton Code of Business Conduct, which Halliburton may amend or supplement from time to time in its sole discretion. 
 (b) Notwithstanding the foregoing, for a period of five (5) years following the Separation Date, the KBR Group will consistently implement and maintain the business practices and standards adopted by the Halliburton Board of Directors
in July 2006 for the KBR Group with respect to internal control procedures relating to use of foreign agents; provided, however, 

  

 58 

 
that the KBR Group may amend such procedures during such 5-year period upon the prior written consent of Halliburton, not to be unreasonably withheld.

 8.15 Antitrust Matters. KBR and Halliburton each agree, on behalf of itself and the members of its Group, to at all times during
the term of this Agreement use reasonable best efforts to assist with the other party’s full cooperation with any Governmental Authority in its investigation of Antitrust Matters and such other party’s investigation, defense and/or
settlement of any claim by any Governmental Authority relating to or arising out of the Antitrust Matters. Without limiting the foregoing, a party’s reasonable best efforts to assist with the other party’s full cooperation contemplated by
the preceding sentence shall include: 
 (a) Without limiting or qualifying the parties’ rights and obligations in
Section 8.4 or Section 3.4, each of Halliburton and KBR agrees, on behalf of itself and the members of its Group, to provide, or cause to be provided, to each other as soon as reasonably practicable after written request therefor, any
Information relating to the Antitrust Matters, in the possession or under the control of such party that the requesting party reasonably needs: (i) to comply with reporting, disclosure, filing or other requirements imposed on the requesting
party (including under applicable securities laws) by a Governmental Authority having jurisdiction over the requesting party, (ii) for use in any Regulatory Proceeding, judicial proceeding or other proceeding or in order to satisfy audit,
accounting, claims, regulatory, litigation, subpoena or other similar requirements, (iii) to allow the other party to defend or settle any claim relating to Antitrust Matters for which such party may be responsible, or (iv) to comply with
its obligations under this Agreement or any Ancillary Agreement; provided, however, that neither party shall be required by this Section 8.15 to violate any Law or waive any attorney-client or other work-product privilege. In the event that any
party determines that such provision of Information pursuant to this Section 8.15 could violate any Law or agreement, or waive any attorney-client or work-product privilege, the parties shall take all reasonable measures to permit the
compliance with such obligations in a manner that avoids any such harm or consequence. 
 (b) Notwithstanding
Section 8.4, each party hereby undertakes, on behalf of itself and the members of its Group, to preserve, maintain and retain all documents, records and other tangible evidence related to Antitrust Matters. 
 (c) Each party agrees, on behalf of itself and the members of its Group, to use reasonable best efforts to (i) make available any of

conducted by a party, the DOJ or other Governmental Authority with respect to the Antitrust Matters.

to promptly inform and disclose to the other party any developments, communications or negotiations between such party or any member of its Group, on the one hand, and any Governmental Authority or third party, on the other hand, with respect to

Third Party Beneficiaries; Assignment. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective legal representatives, successors and assigns, and nothing in this Agreement, express or implied, is
