The Company desires to retain Consultant to serve as an independent contractor to provide consultation and expertise and/or to perform other ad hoc services for the Company, and Consultant is willing to perform such services, on the terms described below. In consideration of the mutual promises contained herein, the Parties agree as follows:

1. Services and Compensation

Consultant shall perform the services (the “Services”) described in more detail on Exhibit A, and the Company agrees to provide Consultant the compensation described on Exhibit A for Consultant’s performance of the Services described therein. Consultant shall devote approximately three (2) days a week of the Consultant’s time, attention and efforts to the performance of the Services.

The Consultant acknowledges and agrees that the Consultant’s appointment is made on the basis of his qualifications and expertise, and that the Consultant will be providing his professional and objective opinions in the context of the Services. Consultant shall comply with all applicable laws and Company safety rules in the course of performing the Services.

2. Confidentiality

A. Definition of Confidential Information. “Confidential Information” means any information (including any and all combinations of individual items of information) that relates to the actual or anticipated business and/or products, research or development of the Company, its affiliates or subsidiaries or to the Company’s, its affiliates’ or subsidiaries’ technical data, trade secrets, or know-how, including, but not limited to, research, product plans, or other information regarding the Company’s, its affiliates’ or subsidiaries’ products or services and markets therefor, customer lists and customers (including, but not limited to, customers of the Company on whom Consultant called or with whom Consultant became acquainted during the term of this Agreement), software, developments, inventions, discoveries, ideas, processes, formulas, technology, designs, drawings, engineering, hardware configuration information, marketing, finances, and other business information that is either (A) disclosed by the Company, its affiliates or subsidiaries, either directly or indirectly, in writing, orally or by drawings or inspection of premises, parts, equipment, or other property of Company, its affiliates or subsidiaries, or (B) otherwise obtained by Consultant in connection with the performance of the Services. Notwithstanding the foregoing, Confidential Information shall not include any such information which Consultant can establish by contemporaneous written documentation (i) was publicly known prior to the time of disclosure to Consultant; (ii) becomes publicly known after disclosure to Consultant through no wrongful action or inaction of Consultant; or (iii) was not obtained in connection with the performance of the Services and is in the rightful possession of Consultant, without confidentiality obligations, at the time of disclosure as shown by Consultant’s then-contemporaneous written records; provided that any combination of individual items of information shall not be deemed to be within any of the foregoing exceptions merely because one or more of the individual items are within such exception, unless the combination as a whole is within such exception.

B. Nonuse and Nondisclosure. During and after the term of this Agreement, Consultant will hold in the strictest confidence, and take all reasonable precautions to prevent any unauthorized use or disclosure of Confidential Information, and Consultant will not (i) use the Confidential Information for any purpose whatsoever other than as necessary for the performance of the Services on behalf of the Company, or (ii) disclose the Confidential Information to any third party without the prior written consent of an authorized representative of Company, except that Consultant may disclose Confidential Information to any third party on a need-to-know basis for the purposes of Consultant performing the Services; provided, however, that such third party is subject to written non-use and non- disclosure obligations at least as protective of Company and the Confidential Information as this Article 2. Consultant may also disclose Confidential Information to the extent compelled by applicable law; provided however, prior to such disclosure, Consultant shall provide prior written notice to Company and seek a protective order or such similar confidential protection as may be available under applicable law. Notwithstanding anything to the contrary in this Agreement or in any terms or conditions attached hereto, should Consultant be compelled to disclose any Confidential Information by applicable law (whether in judicial or administrative proceedings or to comply with requirements otherwise imposed by any governmental or regulatory agency), Consultant shall disclose only that portion of the Confidential Information that is legally required, and shall not disclose any such Confidential Information to any other party other than the party to which Consultant is legally required to disclose the Confidential Information. Consultant agrees that no ownership of Confidential Information is conveyed to the Consultant. Without limiting the foregoing, Consultant shall not use or disclose any Company property, intellectual property rights, trade secrets or other proprietary know-how of the Company to invent, author, make, develop, design, or otherwise enable others to invent, author, make, develop, or design identical or substantially similar designs or products as those developed under this Agreement for any third party. Consultant agrees that Consultant’s obligations under this Section 2.B shall continue after the termination of this Agreement.

C. Other Client Confidential Information. Consultant agrees that Consultant will not improperly use, disclose, or induce the Company to use any proprietary information or trade secrets of any former or concurrent employer of Consultant or other person or entity with which Consultant has an obligation to keep any information in confidence. Consultant also agrees that Consultant will not bring onto the Company’s premises or transfer onto the Company’s technology systems any unpublished document, proprietary information, or trade secrets belonging to any third party unless disclosure to, and use by, the Company has been consented to in writing by such third party.

D. Third Party Confidential Information. Consultant recognizes that the Company has received and in the future will receive from third parties their confidential or proprietary information subject to a duty on the Company’s part to maintain the confidentiality of such information and to use it only for certain limited purposes. Consultant agrees that at all times during the term of this Agreement and thereafter, Consultant owes the Company and such third parties a duty to hold all such confidential or proprietary information in the strictest confidence and not to use it or to disclose it to any person, firm, corporation, or other third party except as necessary in carrying out the Services for the Company consistent with the Company’s agreement with such third party.

E. Federal Defend Trade Secrets Act of 2016. Consultant understands that pursuant to the federal Defend Trade Secrets Act of 2016, Consultant 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. Consultant further understands that nothing contained in this Agreement limits Consultant’s ability to (A) communicate with any federal, state or local governmental agency or commission, including to provide documents or other information, without notice to the Company, or (B) share compensation information concerning Consultant or others, except that this does not permit Consultant to disclose compensation information concerning others that Consultant obtains because Consultant’s job responsibilities require or allow access to such information.

3. Ownership

A. Assignment of Inventions. Consultant agrees that all right, title, and interest in and to any copyrightable material, notes, records, reports, drawings, designs, inventions, improvements, developments, discoveries, ideas and trade secrets conceived, discovered, authored, invented, developed or reduced to practice by Consultant, solely or in collaboration with others, during the term of this Agreement and arising out of, or in connection with, performing the Services under this Agreement and any copyrights, patents, trade secrets, mask work rights or other intellectual property rights relating to the foregoing (collectively, “Inventions”), are the sole property of the Company. Consultant also agrees to promptly make full written disclosure to the Company of any Inventions and to deliver and assign (or cause to be assigned) and without additional compensation hereby irrevocably assigns fully to the Company all right, title and interest in and to the Inventions. No rights or licenses, including without limitation to trademarks, inventions, copyrights, patents or other intellectual properties, are implied or granted to Consultant, whether by implication, estoppel or otherwise, under this Agreement.

B. Pre-Existing Materials. Subject to Section 3.A, Consultant will provide the Company with prior written notice if, in the course of performing the Services, Consultant incorporates into any Invention or utilizes in the performance of the Services any invention, discovery, idea, original works of authorship, development, improvements, trade secret, concept, or other proprietary information or intellectual property right owned by Consultant or in which Consultant has an interest, prior to, or separate from, performing the Services under this Agreement (“Prior Inventions”), and the Company is hereby granted a nonexclusive, royalty-free, perpetual, irrevocable, transferable, worldwide license (with the right to grant and authorize sublicenses) to make, have made, use, import, offer for sale, sell, reproduce, distribute, modify, adapt, prepare derivative works of, display, perform, and otherwise exploit such Prior Inventions, without restriction, including, without limitation, as part of or in connection with such Invention, and to practice any method related thereto. Consultant will not incorporate any invention, discovery, idea, original works of authorship, development, improvements, trade secret, concept, or other proprietary information or intellectual property right owned by any third party into any Invention without Company’s prior written permission.

C. Moral Rights. Any assignment to the Company of Inventions includes all rights of attribution, paternity, integrity, modification, disclosure and withdrawal, and any other rights throughout the world that may be known as or referred to as “moral rights,” “artist’s rights,” “droit moral,” or the like (collectively, “Moral Rights”). To the extent that Moral Rights cannot be assigned under applicable law, Consultant hereby waives and agrees not to enforce any and all Moral Rights, including, without limitation, any limitation on subsequent modification, to the extent permitted under applicable law.

D. Further Assurances. Consultant agrees to assist Company, or its designee, at the Company’s expense, in every proper way to secure the Company’s rights in Inventions in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other instruments that the Company may deem necessary in order to apply for, register, obtain, maintain, defend, and enforce such rights, and in order to deliver, assign and convey to the Company, its successors, assigns and nominees the sole and exclusive right, title, and interest in and to all Inventions and testifying in a suit or other proceeding relating to such Inventions. Consultant further agrees that Consultant’s obligations under this Section 3.D shall continue after the termination of this Agreement.

E. Attorney-in-Fact. Consultant agrees that, if the Company is unable because of Consultant’s unavailability, dissolution, mental or physical incapacity, or for any other reason, to secure Consultant’s signature with respect to any Inventions, including, without limitation, for the purpose of applying for or pursuing any application for any United States or foreign patents or mask work or copyright registrations covering the Inventions assigned to the Company in Section 3.A, then Consultant hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as Consultant’s agent and attorney-in-fact, to act for and on Consultant’s behalf to execute and file any papers and oaths and to do all other lawfully permitted acts with respect to such Inventions to further the prosecution and issuance of patents, copyright and mask work registrations with the same legal force and effect as if executed by Consultant.
