EFFECTIVE DATE: July 1, 2022

David Whitescarver (“Consultant”)

RECITAL:

CSI and Consultant desire to enter into an arrangement by which Consultant will provide consulting services to CSI pursuant to the terms and conditions contained in this Agreement.

AGREEMENT:

In consideration of the mutual benefits contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1.Term. This Agreement will be effective as of the Effective Date set forth above and will continue for 12 months, unless earlier terminated as provided in paragraph 8 herein. This Agreement may be renewed as mutually agreed upon in writing between the parties.

2.Services. During the Consulting Period, Consultant will provide his expertise and knowledge to CSI from time to time and at such locations as mutually agreed upon by Consultant and CSI from time to time (the “Services”); provided, however, that in no event shall such services be greater than 20 hours per month (which is less than twenty percent (20%) of the level of services performed by Consultant for CSI over the 36-month period ending on June 30, 2022). Consultant will have primary control over the means and manner of performing the Services but will perform the Services in a quality and efficient manner in accordance with the reasonable requirements of CSI and will respond promptly to requests. Consultant understands that CSI will not provide Consultant any training for Consultant’s performance of the Services under this Agreement. CSI understands that Consultant may provide services to other entities during the Consulting Period, provided Consultant complies with this Agreement and Sections 9-14 of his Employment Agreement with CSI dated May 11, 2017 (the “Prior Employment Agreement”). Consultant will provide all materials, equipment and supplies necessary to perform the Services.

3.Payment. Payment to Consultant for the Services will be $300.00 per hour. Consultant will invoice CSI for such Services following completion of such Services and any pre-approved expenses incurred. Invoices will be paid within 30 days of receipt.

4.Ownership. Consultant hereby acknowledges that all information, enhancements, alterations, modifications, improvements, discoveries, ideas, processes, designs, trade secrets or other useful technical information or know how relating to CSI’s products, devices, processes or procedures, or otherwise prepared for the benefit of CSI or its customers (the “Works”) developed or suggested by Consultant will be “works made for hire” (as defined in 17 U.S.C. §101 (1976), as amended) for CSI, and as such will be the exclusive property of CSI. If any Work is held not to be “work made for hire,” Consultant hereby assigns to CSI all of his right, title and interest in such Work. Consultant hereby assigns to CSI all of his right, title and interest in the Works. Consultant will give all assistance that CSI reasonably requires to perfect, protect and use CSI’s rights to the Works. In particular, Consultant will sign all documents, do all things and supply all information that CSI may reasonably deem necessary or desirable to enable CSI to obtain patent, copyright or trademark protection for the Works anywhere in the world. Consultant warrants that he has the right to use any copyrightable materials used by Consultant under this Agreement or otherwise in connection with the Services and that no rights of others are infringed by his work hereunder.

5.Consultant’s Inventions. All information disclosed by Consultant to CSI during the Consulting Period will be presumed to be developed and disclosed pursuant to the terms of this Agreement and will belong to CSI as provided in paragraph 4 above. If Consultant has developed an idea or invention that he considers to be Consultant’s property but that he wants to disclose to CSI for consideration for development, Consultant must clearly identify such information as being owned by him prior to disclosure to CSI and a separate CSI disclosure document will be executed by CSI prior to disclosure of such ideas and/or invention by Consultant.

6.Confidential Information.

a.For purposes of this Agreement, “Confidential Information” means any information or computation of information not generally known that is proprietary to CSI and includes, without limitation, all trade secrets, inventions and information contained in or relating to CSI’s product development and designs, tolerances, manufacturing methods, processes, techniques, composition of products, plant default, tooling, marketing plans or proposals, strategies, research and development activities and plans, clinical research activities, data and plans, customer information, sales information, financial information, clinical information, corporate development and financing matters, intellectual property, and all Works.

b.Nondisclosure. During the Consulting Period and thereafter, Consultant will hold the Confidential Information in strictest of confidence and will not, without the prior written authorization of CSI, divulge, disclose, transfer, convey, communicate or make accessible to any person or use in any way the Confidential Information for any reason including the Consultant’s own or another’s benefit or permit the same to be used in competition with CSI. Notwithstanding anything to the contrary in this Agreement or otherwise, nothing will limit Consultant’s rights under applicable law to provide truthful information to any governmental entity or to file a charge with or participate in an investigation conducted by any governmental entity. Furthermore, Consultant is hereby notified that the immunity provisions in Section 1833 of title 18 of the United States Code provide that an individual cannot be held criminally or civilly liable under any federal or state trade secret law for any disclosure of a trade secret that is made (1) in

confidence to federal, state or local government officials, either directly or indirectly, or to an attorney, and is solely for the purpose of reporting or investigating a suspected violation of the law, (2) under seal in a complaint or other document filed in a lawsuit or other proceeding, or (3) to his attorney in connection with a lawsuit for retaliation for reporting a suspected violation of law (and the trade secret may be used in the court proceedings for such lawsuit) as long as any document containing the trade secret is filed under seal and the trade secret is not disclosed except pursuant to court order.

c.Insider Trading Restrictions. Consultant acknowledges that he is aware, and that he has been advised, that United States securities laws prohibit any person having material, non-public information about a company from purchasing or selling securities of that company.

7.Independent Contractor. Consultant is and will remain an independent contractor and is not and will not be deemed to be an employee of CSI. CSI will not treat Consultant as an employee for federal, state, or local tax purposes or for any other purpose. CSI will not withhold or pay payroll or employment taxes of any kind with respect to any amounts that Consultant is paid under this Agreement, including, but not limited to, FICA, FUTA, federal and state personal income tax, state disability insurance tax, and state unemployment insurance benefits tax. Consultant is personally responsible for making all filings with and payments to the Internal Revenue Service and state and local taxing authorities as are appropriate to Consultant’s status as an independent contractor and Consultant’s employees or other business operations. CSI has not obtained and will not obtain workers’ compensation insurance for Consultant. Consultant will comply with the workers’ compensation laws with respect to Consultant, if applicable. Consultant understands that he is not entitled to unemployment benefits or any other benefits normally afforded to an employee of CSI due to his status as an independent contractor. Consultant will have no authority or right under any circumstance whatsoever to incur any indebtedness in the name of CSI, or otherwise to bind or purport to bind CSI in any manner or thing whatsoever. Consultant will comply with all federal, state, and local laws, and rules and regulations that now apply or may in the future apply to Consultant. Neither this Agreement nor the relationship between the parties constitutes a partnership, franchise or joint venture. Consultant will be solely and entirely responsible for Consultant’s acts in performing Services under this Agreement.
