CONSULTING AND SERVICES AGREEMENT

This Consulting and Services Agreement (“Agreement”) is made as of July 27, 2017 by and between NuVasive, Inc. (“NuVasive” or “Company”) and Jason Hannon, an individual (“Consultant”) (individually referred to herein as a “Party” or collectively the “Parties”).

WHEREAS, NuVasive is a medical device company that develops, manufactures and supplies certain spinal and orthopedic implants and other associated equipment, supplies and services and desires to retain Consultant for the performance of certain strategic sales and operational consulting services, as more fully described herein.

WHEREAS, Consultant has the appropriate expertise and qualifications to consult with the Company regarding the sales of certain of its products and services.

NOW, THEREFORE, the Parties agree as follows:

(a)         Services. Consultant shall perform the Services specified in Exhibit A (the “Services”). Consultant represents, warrants and covenants that Consultant will perform the Services under this Agreement in a timely, professional and workmanlike manner and that all materials, information and deliverables provided to Company will comply with the requirements set forth in Exhibit A.

(b)         Payment. The Company will pay to Consultant, as full and complete payment for the performance of the Services, the compensation described in Exhibit A, in the time and manner of payment described on Exhibit A. Consultant acknowledges that he is not entitled to any other compensation or remuneration of any kind whatsoever, except as outlined in this Agreement.

(c)         Expenses. Consultant is not expected nor required to generate any business related expenses; however, should he do so without advance written notice to Company and the Company’s approval of such expenses, he is responsible for all such expenses. The Company shall reimburse Consultant for all pre-approved out-of-pocket expenses incurred by Consultant in connection with the performance of the Services, provided that Consultant provides accounts or invoices therefor evidencing such expenses.

(a)         Independent Consultant. Consultant is an independent contractor and is not an agent or employee of, and has no authority to bind, the Company by contract or otherwise in any matter whatsoever, unless otherwise specifically provided in writing by the

Company. Consultant will perform the Services under the general direction of the Company, but Consultant will determine, in Consultant’s sole discretion, the manner and means by which the Services are to be accomplished, subject to the requirement that Consultant shall at all times comply with applicable law. The Company has no right or authority to control the manner or means by which the Services are accomplished. Consultant shall not be considered under the provisions of this Agreement or otherwise as having any employee status or as being entitled to participate in any benefit plans or arrangements by the Company provided to its regular employees.

(b)         Employment Taxes and Benefits. No part of the Compensation paid to Consultant pursuant to this Agreement will be subject to withholding by the Company for the payment of any social security, federal, state, or any other employee payroll taxes. The Company will regularly report amounts paid to Consultant under this Agreement to the Internal Revenue Services as required by law, and Consultant will be issued an IRS Form 1099 regarding any payments he receives from the Company. The Consultant is solely responsible for payment of all income, social security, employment-related, or other taxes incurred as a result of the performance of Services by Consultant under this Agreement. Consultant will indemnify and hold harmless the Company from and against any and all tax liability related to this Agreement as well as any claim, actions, or charges arising out of or cause by Consultant’s classification as an independent contractor.

(a)         Confidential Information. Consultant recognizes and acknowledges that Consultant will acquire information and materials from the Company and knowledge about the business, products, methods, policies, plans, strategies, processes, procedures, reports, analyses, finances, experimental work, intellectual property, trade secrets, computer programs, designs, technology, know-how, inventions (whether patentable or not), works of authorship, customers, clients, employees, consultants and suppliers and other data of the Company and its affiliates from the Company and that all such knowledge, information and materials acquired are and will be the trade secrets and confidential and proprietary information of the Company (collectively “Confidential Information”). Consultant understands that the foregoing list of information and materials is not exhaustive, and that Confidential Information also includes other information that is marked or otherwise identified as confidential or proprietary, or that would otherwise appear to a reasonable person to be confidential or proprietary in the context and circumstances in which the information is known or used. Consultant further understands that the goodwill of the Company depends, among other things, upon keeping such information confidential and that unauthorized disclosure of the Confidential Information would irreparably damage the Company; and that by reason of Consultant’s duties under this Agreement and any other agreement between the Company and Consultant pertaining to Consultant’s Services, Consultant may come into possession of Confidential Information, even though Consultant may not himself take any direct part in or furnish the services performed for the Company’s clients or customers. Consultant’s obligations under this section do not apply to any

Confidential Information that Consultant can demonstrate (a) was in the public domain at or subsequent to the time the Confidential Information was communicated to Consultant by Company through no fault of Consultant; (b) was rightfully in Consultant’s possession free of any obligation of confidence at or subsequent to the time the Confidential Information was communicated to Consultant by Company; or (c) was independently developed by employees of Consultant without use of, or reference to, any Confidential Information communicated to Consultant by Company. A disclosure of any Confidential Information by Consultant (a) in response to a valid order by a court or other governmental body or (b) as otherwise required by law will not be considered to be a breach of this Agreement or a waiver of confidentiality for other purposes; provided, however, that Consultant provides prompt prior written notice thereof to Company to enable Company to seek a protective order or otherwise prevent the disclosure.

(b)         Nondisclosure and Nonuse. Consultant agrees to hold all Confidential Information in confidence, not to directly or indirectly disclose, publish communicate or make available Confidential Information, or allow it to be disclosed, published, communicated or made available, in whole or in part, to any entity or person or use it commercially, except in performing the Services, and not to allow any unauthorized person access to it. Consultant will not at any time during or after the Term of this Agreement disclose any Confidential Information to any third-party person or entity, or permit any third-party person or entity to examine and/or make copies of any reports or any documents prepared by Consultant or that come into the possession or under the control of the Consultant by reason of Consultant’s Services without the Company’s express written consent.

(c)         Assignment of Rights. All Confidential Information and all title, patents, patent rights, copyrights, trade secret rights, sui generis database rights and other intellectual or industrial property rights of any sort anywhere in the world (collectively “Rights”) in connection therewith shall be the sole property of the Company. Consultant hereby assigns to the Company any Rights Consultant may have or acquire in such Confidential Information. At all times, both during the Term of this Agreement and after its termination, Consultant will keep in confidence and trust and will not use or disclose any Confidential Information or anything related to it without the prior written consent of an officer of the Company.

(d)         Injunctive Relief. Consultant acknowledges that disclosure or unauthorized use of any Confidential Information by Consultant and/or breach of the covenants set forth above will give rise to irreparable injury to the Company or the owner of such information, inadequately compensable in damages. Consultant further acknowledges and agrees that the covenants contained in this Agreement are necessary for the protection of the Company’s legitimate business interests and are reasonable in scope and content. In the event of a breach or threatened breach by Consultant of any of the provisions hereof, Consultant hereby consents and agrees that the Company shall be entitled to pre-judgment injunctive relief or similar equitable relief to restrain Consultant from

committing or continuing any such breach or threatened breach.

(e)         Non-Interference with Business. During the Term of this Agreement, Contractor agrees not to perform any service that may utilize any of the Confidential Information obtained from the Company or any Confidential Information developed during the course of performing the Services for the Company or during Consultant’s prior employment with the Company, for any other person or entity, and - in particular - any other person or entity engaged in the development, manufacture, distribution, or sales of health care products or services.

(f)         Non-Solicitation. Consultant agrees that during the Term, he shall not, for any or no reason, whether directly on such person’s own behalf or as an employee, independent contractor, partner, owner, officer, director of any entity, or in any other capacity: (1) solicit, entice, persuade, induce, call upon or provide services to any of the customers, accounts or clients that Consultant worked with, had responsibility or oversight of, provided services related to, or learned significant information about during the course of Consultant’s engagement with the Company for any purpose other than for the benefit of the Company; and/or (2) induce or influence, or seek to induce or influence, any person who is employed or engaged by the Company (as an agent, employee, independent contractor, or in any other capacity), or any successor thereto, with the purpose of obtaining such person as an employee, consultant or independent contractor for a business competitive with the Company, or causing such person to terminate or reduce his or her employment, agency or relationship with the Company, or any successor thereto.

(a)         Consultant will indemnify and hold harmless Company from and against any and all claims, suits, actions, demands, and proceedings against Company and all losses, costs, and liabilities directly related to such claims, suits, actions, demands, and proceedings against Company or its subsidiaries or affiliated entities, arising out of or related to (i) any material breach of this Agreement by Consultant or (ii) Consultant’s gross negligence and/or fraud in the performance of the Services under this Agreement.

(b)         The Indemnification Agreement entered into as of May 14, 2014 by the Parties is hereby amended by changing the definition of “Agent” therein to include Consultant’s capacity pursuant to this Agreement as a consultant.

At all times, Consultant will observe Company’s rules and regulations with respect to Consultant’s conduct, health, safety, anti-harassment/discrimination/retaliation and protection of persons and property.

(a)         Ownership. NuVasive is, and shall be, the sole and exclusive owner of all right, title and interest in and to all Company Innovations that are created, made, conceived, reduced to practice or authored by Consultant in the course of performing the Services including any and all intellectual property rights therein. In this Agreement, “Company Innovations” means all discoveries, designs, developments, improvements, inventions (whether or not protectable under patent laws), works of authorship, information fixed in any tangible medium of expression (whether or not protectable under copyright laws), trade secrets, know-how, ideas (whether or not protectable under trade secret laws), mask works, trademarks, service marks, trade names and trade dress that Consultant, solely or jointly with others, creates, derives, conceives, develops, makes or reduces to practice under the Services Consultant provides pursuant to this Agreement.

(b)         Disclosure and Assignment of Company Innovations. Consultant agrees to maintain adequate and current records of all Company Innovations, which records shall be and remain the property of Company. Consultant agrees to promptly disclose and describe to Company all Company Innovations. Consultant represents, warrants and covenants that all Company Innovations shall be free and clear of any liens and encumbrances. Consultant hereby does and will irrevocably assign to Company or Company’s designee all of Consultant’s right, title and interest in and to any and all Company Innovations and all associated records, such assignment to occur with respect to each Company Innovation at the time the Company Innovation is first conceived, made, derived, developed, written or created, and regardless of when the Company Innovation is first conceived, made, derived, developed, written or created. To the extent any of the rights, title and interest in and to Company Innovations cannot be assigned by Consultant to Company, Consultant hereby grants to Company an exclusive, royalty-free, transferable, irrevocable, worldwide, fully paid-up license (with rights to sublicense through multiple tiers of sublicensees) to fully use, practice and exploit those non-assignable rights, title and interest, including, but not limited to, the right to make, use, sell, offer for sale, import, have made, and have sold, the Company Innovations. To the extent any of the rights, title and interest in and to the Company Innovations can neither be assigned nor licensed by Consultant to Company, Consultant hereby irrevocably waives and agrees never to assert the non-assignable and non-licensable rights, title and interest against Company, any of Company’s successors in interest, or any of Company’s customers. If any Company Innovations include any work of authorship that qualifies as a “work made for hire” as defined in subclause (2) under Section 101 of the Copyright Law of the United States (Title 17 of the United States Code, as may be amended from time to time), Company and Consultant agree that Company owns such work of authorship as a work made for hire under such section.

(c)         Assistance. Consultant agrees to perform, during and after the Term of this Agreement, all acts that Company deems necessary or desirable to permit and assist Company, at its expense, in obtaining, perfecting and enforcing the full benefits, enjoyment, rights and title throughout the world in the Company Innovations as provided to Company under this Agreement. If Company is unable for any reason to secure Consultant’s signature to any document required to file, prosecute, register or memorialize the assignment of any

rights under any Company Innovations as provided under this Agreement, Consultant hereby irrevocably designates and appoints Company and Company’s duly authorized officers and agents as Consultant’s agents and attorneys-in-fact to act for and on Consultant’s behalf and instead of Consultant to take all lawfully permitted acts to further the filing, prosecution, registration, memorialization of assignment, issuance and enforcement of rights in, to and under the Company Innovations, all with the same legal force and effect as if executed by Consultant. The foregoing is deemed a power coupled with an interest and is irrevocable.

(a)         No Conflict. Consultant represents and warrants to the Company that he is not now nor shall he be a party to any other agreement or under any obligation to or restriction by any third-party which would prevent Consultant from entering into or performing this Agreement.

(b)         Notice; Non-Disclosure. During the Term of the Agreement, Consultant agrees to promptly and properly advise NuVasive of all matters coming to his attention that could, in any manner, materially and adversely affect the business or interests of NuVasive.
