RECITALS WHEREAS, Employer and Employee entered into an Executive Agreement dated January 1, 2019 (the "Executive Agreement"), and Employer and Employee intend this Agreement to replace such Executive Agreement; and WHEREAS, Employer desires to continue to employ Employee pursuant to the terms and conditions and for the consideration set forth in this Agreement, and Employee desires to continue to be employed by Employer pursuant to such terms and conditions and for such consideration; NOW THEREFORE, for and in consideration of the mutual promises, covenants, and obligations contained herein, Employer and Employee agree as follows: ARTICLE 1: EMPLOYMENT AND DUTIES: 1.1 Employer agrees to continue to employ Employee, and Employee agrees to continue to be employed by Employer, as of the Effective Date and continuing until the date of termination of Employee's employment pursuant to the provisions of Article 3, subject to the terms and conditions of this Agreement. 1.2 As of the Effective Date, Employee will be employed as President, Western Hemisphere. Employee agrees to serve in the assigned position or in such other executive capacities as may be requested from time to time by Employer and to perform diligently and to the best of Employee's abilities the duties and services relating to such position as reasonably determined by Employer, as well as such additional or different duties and services appropriate to such positions which Employee from time to time may be reasonably directed to perform by Employer. 1.3 Employee shall at all times comply with and be subject to such policies and procedures as Employer may establish from time to time, including, without limitation, the Halliburton Company Code of Business Conduct (the "Code of Business Conduct"), Company Policy 3-90020, "Director and Executive Compensation Administration" (with respect to the prohibition of discretionary payments in certain situations), Company Policy 3-90050, "Termination of Officers Who Participate in Violations or Disregard Supervisory Responsibilities", Company Policy 3-90070, "Recoupment of Incentive Compensation Following a Restatement," and Company

&nbsp;&nbsp;&nbsp;&nbsp;2 of 16 Policy 3-90080, "Supplemental Policy for Recoupment of Incentive-Based Compensation," all of which have been made available to Employee and are available under "COBC" or "Policies" as posted on Halworld located at http://halworld.corp.halliburton.com, as well as Section 35(a) of the Halliburton Company By-Laws (with respect to the limitations on the advancement of legal expenses), a copy of which has been made available to Employee. By signing this Agreement, Employee hereby represents and warrants that Employee has read, understood and agrees to the terms and conditions contained in such Code of Business Conduct, policies, and By-Laws. 1.4 Employee shall, during the period of Employee's employment by Employer, devote Employee's full business time, energy, and best efforts to the business and affairs of Employer.

The foregoing notwithstanding, the parties recognize and agree that Employee may engage in passive personal investments and other business activities which do not conflict with the business and affairs of the Halliburton Entities or interfere with Employee's performance of Employee's duties hereunder. Employee may not serve on the board of directors of any entity other than a Halliburton Entity while employed by Employer without the approval thereof in accordance with Employer's policies and procedures regarding such service. Employee shall be permitted to retain any compensation received for approved service on any unaffiliated corporation's board of directors to the extent permitted under a Halliburton Entity's policies and procedures. 1.5 Employee acknowledges and agrees that Employee owes a fiduciary duty of loyalty, fidelity and allegiance to act at all times in the best interests of Employer and the other Halliburton Entities and to do no act which would, directly or indirectly, injure any such entity's business, interests, or reputation. It is agreed that any direct or indirect interest in, connection with, or benefit from any outside activities, particularly commercial activities, which interest might in any way adversely affect Employer, or any Halliburton Entity, involves a possible conflict of interest. In keeping with Employee's fiduciary duties to Employer, Employee agrees that Employee shall not knowingly become involved in a conflict of interest with Employer or the Halliburton Entities, or upon discovery thereof, allow such a conflict to continue. Moreover, Employee shall not engage in any activity that might involve a possible conflict of interest without first obtaining approval in accordance with the applicable Halliburton Entity's policies and procedures. 1.6 Nothing contained herein shall be construed to preclude the transfer of Employee's employment to another Halliburton Entity ("Subsequent Employer") as of, or at any time after, the Effective Date and no such transfer shall be deemed to be a termination of employment for purposes of Article 3 hereof; provided, however, that, effective with such transfer, all of Employer's obligations hereunder shall be assumed by and be binding upon, and all of Employer's rights hereunder shall be assigned to, such Subsequent Employer and the defined term "Employer" as used herein shall thereafter be deemed amended to mean such Subsequent Employer. Except as otherwise provided above, all of the terms and conditions of this Agreement, including without limitation, Employee's rights and obligations, shall remain in full force and effect following such transfer of employment.

ARTICLE 4: OWNERSHIP AND PROTECTION OF INTELLECTUAL PROPERTY AND CONFIDENTIAL INFORMATION: 4.1 All information, ideas, concepts, improvements, discoveries, works of authorship, and inventions, whether patentable or copyrightable or not, which are conceived, reduced to practice, authored, made, developed or acquired by Employee, individually or in conjunction with others, in the scope of Employee's employment by Employer or any of its affiliates, and/or during the term of Employee's employment (whether during business hours or otherwise and whether on Employer's premises or otherwise) which relate to the business, products or services of Employer or its affiliates (including, without limitation, all such information relating to any corporate opportunities, research, financial and sales data, pricing and trading terms, evaluations, opinions, interpretations, acquisition prospects, the identity of customers or their requirements, the identity of key contacts within the customer's organizations or within the organization of acquisition prospects, or marketing and merchandising techniques, prospective names, and marks), and all documents, things, writings and items of any type or in any media embodying any of the foregoing (collectively, "Developments"), and any and all proprietary rights of any kind thereto, including without limitation all rights relating to patents, copyrights, trade secrets, and trademarks, shall be the sole and exclusive property of Employer or its affiliates, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;9 of 16 and any and all proprietary rights of any kind thereto, including without limitation all rights relating to patents, copyrights, trade secrets, and trademarks. Employee acknowledges that the assignment of Employee's entire right, title and interest in and to any and all such Developments to Employer is deemed effective upon the earliest of the conception, development, first reduction to practice, or creation of the Development by Employee. Employee agrees, without further consideration and upon request by Employer, to assist and cooperate with Employer by executing any and all documents, and by performing any and all lawful acts, necessary to document the assignment to Employer (or Employer's designee) of Employee's right, title and interest in and to any and all such Developments and to assist Employer (or Employer's designee) in perfecting such rights. 4.2 In connection with its employment of Employee, Employer shall provide to Employee such Confidential Information of Employer as is reasonably necessary for Employee to perform Employee's obligations hereunder. Employee agrees that "Confidential Information" as used herein shall include, without limitation, Employer's trade secrets, confidential and/or proprietary information, and all other information and data that is not generally known to third persons who could derive economic value from its use or disclosure, including, but not limited to, Employer's strategies, methods, products, software, books, records, data and technical information concerning its products, equipment, services, and processes, procurement procedures and pricing techniques, and the names of and other information (such as credit and financial data) concerning its vendors, customers and business affiliates. Employee agrees that such Confidential Information constitutes valuable, special, and unique assets which Employer or its affiliates use in their business to obtain a competitive advantage over their competitors. Employee further agrees that protection of such Confidential Information against unauthorized disclosure and use is of critical importance to Employer and its affiliates in maintaining their competitive position. Employee shall not, at any time during or after the term of employment, use, publish, disclose, claim ownership of, communicate, divulge or send to others, access, or take, any Confidential Information of Employer or its affiliates, including Employer's vendors, consultants, joint ventures, or customers, except to the extent needed to carry out Employee's obligations hereunder, or as otherwise authorized in writing by Employer. Employee also agrees that Employee will not upload or cause to be uploaded to any online electronic data storage site (e.g., "cloud" storage sites) any Confidential Information. Employee acknowledges and agrees that any unauthorized use or disclosure of such Confidential Information would cause irreparable harm to Employer. Confidential Information shall not include information in the public domain (but only if the same becomes part of the public domain through a means other than a use or disclosure prohibited hereunder). The above notwithstanding, a disclosure shall not be unauthorized to the extent (i) it is required by law or by a court of competent jurisdiction or (ii) it is required in connection with any judicial, arbitration, dispute resolution or other legal proceeding in which Employee's legal rights and obligations as an employee or under this Agreement are at issue; provided, however, that Employee shall, to the extent practicable and lawful in any such event, give prior notice to Employer of Employee's intent to disclose any such confidential business information in such context so as to allow Employer or its affiliates an opportunity (which Employee will not oppose) to obtain such protective orders or similar relief with respect thereto as may be deemed appropriate, and that Employee shall limit any such disclosure to that required by the foregoing circumstances.

Upon termination of Employee's employment, Employee promptly shall deliver the same, and all copies thereof, to Employer. 4.4 If, in the performance of Employee's duties for Employer, it is necessary to temporarily remove documents or information from Employer's premises, Employee will remove only such documents or information as necessary to perform such duties and will immediately return such documents or information to Employer's premises upon completion of such duties and at any time upon request. Employee further agrees not to commingle such documents or information with Employee's personal records and documents. Employee agrees to maintain any back-up copies of documents or information at Employer's premises and not to maintain any back- up copies away from Employer's premises. All documents or information (including computer records, facsimile and e-mail) and materials created, received or transmitted in connection with Employee's work or using Employer facilities are presumptively Employer's property and subject to inspection by Employer at any time. Any computer media (e.g., disks, tapes, external thumb drives, flash drives, external hard drives, DVDs or CDs), personally owned computers of Employee (including the contents of such computer's hard drive) and data storage accounts on which any Employer documents or information has been stored may also be reviewed by Employer to determine if they contain any Confidential Information. 4.5 Pursuant to the Defend Trade Secrets Act of 2016, Employee acknowledges that an individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (a) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. 4.6 For purposes of this Article 4, "affiliates" shall mean entities in which Employer has a 20% or more direct or indirect equity interest. ARTICLE 5: POST-EMPLOYMENT COVENANTS 5.1 In consideration of the access to the Confidential Information provided by Employer, the payment made under Section 3.4 and the other consideration provided herein, and to protect Employer's Confidential Information, and the goodwill, customer and employee base, and contractual relationships of Employer, Employee agrees to the provisions of Sections 5.2, 5.3 and 5.4. 5.2 Employee agrees that, for a period of two (2) years following termination of employment, Employee shall not, anywhere in the world, directly or indirectly, either (a) solicit, encourage, or induce to terminate or reduce its business with Employer, or (b) provide any

&nbsp;&nbsp;&nbsp;&nbsp;11 of 16 products and/or services that compete directly with products and/or services provided, marketed, and/or under development by Employer at any time during the two (2) years preceding the termination of Employee's employment, in both cases, to any person or entity who paid or engaged Employer for products and/or services, or who received the benefit of Employer's products and/or services, or with whom Employee had any substantial dealings while Employee was employed by Employer, during the two (2) years preceding Employee's termination of employment with Employer. 5.3 Employee further agrees that, for a period of two (2) years following termination of employment, Employee shall not, anywhere in the world, solicit, directly or indirectly, or cause or permit others to solicit, directly or indirectly, any Former or Current Employee. The term "solicit" as used in this Section 5.3 shall have the same meaning provided for such term in Section 3.7 above. 5.4 Employee further agrees that, for a period of two (2) years following termination of employment, Employee shall not engage, directly or indirectly, either as proprietor, stockholder, partner, director, officer, member, employee, consultant, or otherwise, (i) in any existing or future business, or in any existing or future division or unit of a commercially diverse business enterprise, anywhere in the world, that is owned in whole or in part or effectively controlled by any of the companies listed or described in Section 3.8(a) above; or (ii) in any existing or future business operating in North America or in any of the ten countries outside of North America that produced the highest revenues for Employer in the year proceeding Employee's termination of employment that offers, sells, or provides equipment, products or services that compete with Employer's equipment, products or services, except as permitted by Section 3.8(b) above. 5.5 Employee agrees that (a) the covenants contained in this Agreement are necessary for the protection of Employer's business, goodwill, customer and employee relationships and Confidential Information, and (b) the compensation and other consideration received by Employee, including access to Confidential Information, are based on the parties' agreement to such covenants. Employee represents and warrants that the time, scope of activity and geographic area restricted by Sections 3.6, 3.7, 3.8, 5.2, 5.3, and 5.4 are reasonable, especially in view of the worldwide scope of the business operations of Employer, Employee's position and responsibilities with Employer, and the nature of the Confidential Information, that the enforcement of those restrictions contained in Sections 3.6, 3.7, 3.8, 5.2, 5.3, and 5.4 would not be unduly burdensome to or impose any undue hardship on Employee, and that Employee will be able to earn a reasonable living while abiding by such covenants. Employee agrees that the restraints and provisions of Sections 3.6, 3.7, 3.8, 5.2, 5.3, and 5.4 are no greater than necessary, and are as narrowly drafted as reasonably possible, to protect the legitimate interests of Employer, including the Confidential Information and trade secrets of Employer. Employee irrevocably waives all defenses to the strict enforcement of the covenants contained in Sections 3.6, 3.7, 3.8, 5.2, 5.3, and 5.4, and agrees that the breach or violation, or threat thereof, of the obligations and covenants set forth in any of such Sections shall entitle Employer, as a matter of right, to an injunction without the requirement of a bond, restraining any further or continued breach or violation of said obligations and covenants. The parties agree

&nbsp;&nbsp;&nbsp;&nbsp;12 of 16 and acknowledge that the nature of Employer's business, including the locations of its projects, vendors, customers, and potential customers, is global in nature. Accordingly, the parties expressly agree that the foregoing restrictions on Employee need to be global in territorial scope to adequately protect Employer's business, goodwill, customer and employee relationships and Confidential Information, and that such global territorial restriction is reasonable in view of Employer's business, Employee's position and responsibilities with Employer, and Employee's access to the Confidential Information of Employer. If the scope of any restriction contained in Sections 3.6, 3.7, 3.8, 5.2, 5.3, and 5.4 is deemed by a court or arbitrator to be broader than reasonable, which the parties agree should not be the case, then such restriction shall be enforced to the maximum extent permitted by law, and Employee and Employer hereby agree that such scope may be modified accordingly in any proceeding brought to enforce such restriction. 5.6 The provisions of Sections 3.6, 3.7, 3.8, 5.2, 5.3, and 5.4 are, and shall be construed as, independent covenants, and no claimed or actual breach of any contractual or legal duty by Employer shall excuse or terminate Employee's obligations under this Agreement or preclude Employer from obtaining injunctive relief for Employee's violation, or threatened violation, of any of those provisions. The restrictive periods set forth in this Agreement shall not expire, and shall be tolled, during any period in which Employee is in violation of this Agreement. 5.7 Employee agrees that Employee shall not make, directly or indirectly, whether in writing, orally or electronically, any negative, derogatory or other comment that could reasonably be expected to be detrimental to the Halliburton Entities, their business or operations or any of their current or former employees, officers or directors. Employee consents to Employer showing this Agreement to any third party believed by Employer to be a prospective or actual employer of Employee, and to insisting on Employee's compliance with the terms of this Agreement. Notwithstanding the foregoing, nothing in this Agreement, including the non-disclosure provisions above, limits Employee's ability to communicate with the Securities and Exchange Commission (or any other governmental agency) regarding any possible violations of law, to otherwise participate in any investigation or proceeding that may be conducted by a governmental agency (including providing documents or other information without notice to Employer), or to receive any award for information provided to a governmental agency. ARTICLE 6: MISCELLANEOUS: 6.1 Except as otherwise provided in Section 4.5 hereof, for purposes of this Agreement, the terms "affiliate" or "affiliated" means an entity who directly, or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with a Halliburton Entity or in which a Halliburton Entity has a 50% or more equity interest. 6.2 This Agreement may be executed in one or more counterparts, each of which shall be deemed an original and all of which together shall constitute a single instrument. Execution and delivery of this Agreement electronically signed by Employee via DocuSign or such other commercially available electronic software which results in confirmed signatures delivered electronically shall constitute a valid and binding execution and delivery of this Agreement by Employee. Such electronic copies shall constitute enforceable original documents and shall be

&nbsp;&nbsp;&nbsp;&nbsp;13 of 16 considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. Employee shall not raise the use of electronic mail attachment in "pdf" or similar format to deliver a signature, or the fact that any signature was transmitted or communicated as an attachment to an electronic mail message, as a defense to the formation of a contract and waives any such defense. An electronically scanned copy of a signature shall constitute and shall be deemed to be sufficient evidence of Employee's execution of this Agreement, without necessity of further proof. It shall not be necessary in making proof of this Agreement to produce or account for more than one such counterpart. 6.3 For purposes of this Agreement, notices and all other communications provided for herein shall be in writing and shall be deemed to have been duly given when received by or tendered to Employee or Employer, as applicable, by pre-paid courier or by United States registered or certified mail, return receipt requested, postage prepaid, addressed as follows: If to Employer, to Halliburton Company via electronic delivery to the designated E-Sign application; via Email: FHOUEXEC@Halliburton.com or via mail to Halliburton Company at 3000 North Sam Houston Parkway East, Houston, Texas 77032, to the attention of the General Counsel of Halliburton Company, or to such other address as Employee shall receive notice thereof. If to Employee, to Employee's last known personal residence or email address. 6.4 This Agreement shall be governed by and construed and enforced in all respects in accordance with the law of the State of Texas, without regard to principles of conflicts of law, unless preempted by federal law, in which case federal law shall govern; provided, however, that the Dispute Resolution Plan and the Federal Arbitration Act shall govern in all respects with regard to the resolution of disputes hereunder. Employee and Employer further agree that any lawsuit, arbitration, or other proceeding arising out of or related in any way to this Agreement or their relationship shall be commenced and maintained only in the federal or state courts or before an arbitrator in Harris County, Texas, and each party waives any current or future objection to such venue and hereby further agrees to submit to the jurisdiction of any duly authorized court or arbitrator in Harris County, Texas with respect to any such proceeding. 6.5 No failure by either party hereto at any time to give notice of any breach by the other party of, or to require compliance with, any condition or provision of this Agreement shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. 6.6 It is a desire and intent of the parties that the terms, provisions, covenants, and remedies contained in this Agreement shall be enforceable to the fullest extent permitted by law. If any such term, provision, covenant, or remedy of this Agreement or the application thereof to any person, association, or entity or circumstances shall, to any extent, be construed to be invalid or unenforceable in whole or in part, then such term, provision, covenant, or remedy shall be construed in a manner so as to permit its enforceability under the applicable law to the fullest extent permitted by law. In any case, the remaining provisions of this Agreement or the application thereof to any

Accordingly, the parties agree that any such dispute shall, as the sole and exclusive forum, be submitted for resolution through the Dispute Resolution Plan; provided, however, that Employer, on its own behalf and on behalf of any of the Halliburton Entities, shall be entitled to seek a restraining order or injunction in any court of competent jurisdiction to prevent any breach or the continuation of any breach of the provisions of Sections 3.6, 3.7, and 3.8, and Articles 4 and 5 pending initiation or completion of proceedings under the Dispute Resolution Plan. Employee hereby consents that such restraining order or injunction may be granted without the necessity of Employer posting any bond. The parties agree that the resolution of any such dispute through such plan shall be final and binding. A copy of the Dispute Resolution Plan, as currently in effect, has been made available to Employee and is available on Halworld under "DRP" located at http://halworld.corp.halliburton.com. Halliburton Company reserves the right to amend, or discontinue such plan, in accordance with, and subject to, the plan's provisions regarding same. By signing this Agreement, Employee hereby represents and warrants that Employee has read, understood and agrees to the terms and conditions contained in such Dispute Resolution Plan. THE PARTIES ACKNOWLEDGE THAT, BY SIGNING THIS AGREEMENT, THEY ARE KNOWINGLY AND VOLUNTARILY WAIVING ANY RIGHT THAT THEY MAY HAVE TO A JURY TRIAL. 6.8 This Agreement shall be binding upon and inure to the benefit of Employer, to the extent herein provided, Halliburton Entity and any other person, association, or entity which may hereafter acquire or succeed to all or substantially all of the business or assets of Employer by any means whether direct or indirect, by purchase, merger, consolidation, or otherwise. Employee's rights and obligations under this Agreement are personal and such rights, benefits, and obligations of Employee shall not be voluntarily or involuntarily assigned, alienated, or transferred, whether by operation of law or otherwise, without the prior written consent of Employer, other than in the case of Death or incompetence of Employee. 6.9 This Agreement replaces and merges any previous agreements, understandings and discussions pertaining to the subject matter covered herein and therein, including but not limited to the Executive Agreement. This Agreement constitutes the entire agreement of the parties with regard to the terms of Employee's employment, termination of employment and severance benefits, and contains all of the covenants, promises, representations, warranties, and agreements between the parties with respect to such matters. Each party to this Agreement acknowledges that no representation, inducement, promise, or agreement, oral or written, has been made by either party with respect to the foregoing matters which is not embodied herein, and that no agreement, statement, or promise relating to the employment of Employee by Employer that is not contained in this Agreement shall be valid or binding. Any modification of this Agreement will be effective only if it is in writing and signed by each party whose rights hereunder are affected thereby, provided that any such modification must be authorized or approved by the Compensation Committee or its delegate, as appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;15 of 16 6.10 DEFEND TRADE SECRETS ACT NOTICE. Employee is hereby notified in accordance with the Defend Trade Secrets Act of 2016 that Employee will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If Employee files a lawsuit for retaliation against Employer for reporting a suspected violation of law, Employee may disclose Employer's trade secrets to Employee's attorney and use the trade secret information in the court proceeding if Employee files any document containing the trade secret under seal, and does not disclose the trade secret, except pursuant to court order. 6.11 Notwithstanding any provision of the Agreement to the contrary, the following provisions shall apply for purposes of complying with Section 409A of the Internal Revenue Code and applicable Treasury authorities ("Section 409A"): (i) If Employee is a "specified employee," as such term is defined in Section 409A, any payments or benefits that are deferred compensation under Section 409A and are payable or provided as a result of the termination of Employee's employment shall be payable on the date that is the earlier of (a) the date that is six months and one day after Employee's termination, (b) the date of Employee's Death, or (c) the date that otherwise complies with the requirements of Section 409A.
