The Employee further covenants and agrees that, for the period commencing on the Commencement Date and ending one (1) year after the termination of Employee’s employment with the Company, whether with or without Cause or with or without Good Reason, the Employee shall not, except in connection with the performance of the Employee’s duties hereunder, directly or indirectly, whether for or on behalf of the Employee or any other person or entity, knowingly solicit, induce, or attempt to solicit or induce any person or entity to cease or reduce doing business with, or referring patients or business to, the Company and/or its Affiliates, or in any way interfere or attempt to interfere with the relationship between any such person or entity, on the one hand, and the Company or any such Affiliate, on the other hand. 8.4.1. Without limiting the generality of the foregoing, the term “person” or “entity” includes, without limitation, any client, customer, patient, third party payor, governmental agency and/or its fiscal intermediaries, contractor, supplier, licensee, or other business relation of the Company or any of its Affiliates with whom Employee, within the twelve (12) months prior to the termination of Employee’s employment, engaged, had contact with or received Confidential Information about, and (i) that is directly or indirectly receiving goods or services from, or providing goods and services to, the Company and/or any of its Affiliates or (ii) that is directly or indirectly providing or referring any client, customer, or patient to, or otherwise providing or referring business to or for, the Company or any of its Affiliates. 8.5. Covenant Not Hire Employees. The Employee further covenants and agrees that, for the period commencing with the date hereof and ending one (1) year after the termination of Employee’s employment with the Company, whether with or without Cause or with or without Good Reason, the Employee shall not, except in connection with the performance of the Employee’s duties hereunder, directly or indirectly, whether for or on behalf of the Employee or any other person or entity: 8.5.1. induce or attempt to induce any employee of the Company or any of its Affiliates to leave the employ of the Company or such Affiliate, or in any way interfere with the relationship between the Company or any such Affiliate, on the one hand, and any employee thereof, on the other hand; or 8.5.2. solicit for hire or hire any person who was an employee of the Company or any of its Affiliates until six (6) months after such individual’s DocuSign Envelope ID: 9ECAE601-F283-44DF-96B0-37E03A43D927

14 employment relationship with the Company or any such Affiliate has been terminated, provided that the Employee may hire any such person (so long as such person is not a manager or executive officer of the Company or any such Affiliate) who responds to a general advertisement offering employment. 8.6. Remedies. The Employee acknowledges that the covenants contained in this Section 8 are reasonable and necessary protections of the legitimate business interests of the Company; that any violation of these covenants may cause substantial injury and irreparable harm to the Company and its goodwill; that it is extremely difficult, if not impossible, to ascertain the actual damages that would result to the Company in the event of a breach or threatened breach by the Employee of any of the covenants contained in this Section 8; and that the Company would not have entered into this Agreement without receiving the Employee’s additional consideration in binding the Employee to these covenants. Accordingly, the Employee specifically agrees that the Employee’s failure to strictly comply with or perform any of the Employee’s obligations under the provisions of this Section 8 shall constitute a material breach thereof by the Employee, and, in the event of a breach or threatened breach by the Employee of any of the provisions of this Section 8, the Company, in addition to and not in limitation of any other rights, remedies, or damages available to the Company, at law or in equity, shall be entitled to seek a temporary restraining order, preliminary injunction, and permanent injunction in order to prevent or restrain any such breach or threatened breach by the Employee or by any other person or entity directly or indirectly acting for, on behalf of, or with the Employee. No right or remedy granted herein is exclusive of any other right or remedy, but every such right or remedy shall be cumulative and shall be in addition to every other right or remedy herein or now or hereafter existing at law or in equity. 8.7. Construction. 8.7.1. If the Employee violates any covenant contained in this Section 8 and the Company Group brings an action for injunctive or other relief, neither the Company Group shall, as a result of the time involved in obtaining the relief, be deprived of the benefit of the full period of the restrictive covenant. Accordingly, such restrictive covenant shall be deemed to have the duration herein computed from the date the relief is granted, but reduced by the time between the period when the restrictive covenant began to run and the date of the first violation of the restrictive covenant by the Employee. 8.7.2. If any court shall determine that the duration or geographical limit of any restrictive covenant contained in this Section 8 is unenforceable, it is the intention of the Parties that such restrictive covenant shall not thereby be terminated, but shall be deemed amended to the extent required to render it valid and enforceable, and such amendment shall apply only with respect to the operation of this Section 8 in the jurisdiction of the court that has made the adjudication. 8.7.3. The failure of the Company Group to enforce any provision or provisions of this Section 8 shall not in any way be construed to be a waiver of any DocuSign Envelope ID: 9ECAE601-F283-44DF-96B0-37E03A43D927

15 such provision or provisions, nor prevent the Company Group from thereafter enforcing each and every other provision of this Section 8. 8.7.4. The Employee’s agreements and covenants contained in this Section 8 are, and shall be construed as, agreements and covenants separate, independent, and mutually exclusive of any other provision of this Agreement. The existence of any claim or cause of action of the Employee against the Company Group, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company Group of the Employee’s agreements and covenants contained in this Section 8. 8.7.5. All of the Company’s Affiliates, including all members of the Company Group (other than the Company) are specifically hereby named as third- party beneficiaries of this Section 8 with full right, power, and authority to enforce any of the provisions of this Section 8 against the Employee. 8.7.6. The provisions of this Section 8 may be enforced by the Company’s successors and assigns and the Company’s Affiliates, including all members of the Company Group (other than the Company), as third-party beneficiaries. 8.8. Survival. Except as otherwise provided herein, the provisions of this Section 8 shall survive the termination or expiration of this Agreement or the Employee’s employment hereunder for any reason or regardless of the reason whatsoever, whether voluntary or involuntary. 8.9. Exceptions. The Employee’s ownership of less than a one percent (1%) interest in a publicly held entity solely for investment purposes shall not, by itself, be deemed to constitute a breach of Section 8.3 hereof. If the Company terminates the Employee’s employment hereunder without Cause pursuant to Section 6.4.1 hereof or the Employee terminates the Employee’s employment for Good Reason pursuant to Section 6.7 hereof, then the provisions of Section 8.3 hereof shall not apply following such termination; provided, however, that all other provisions of this Section 8 shall continue in full force and effect to the extent applicable. 8.10. Review by Employee. THE EMPLOYEE HAS CAREFULLY READ AND CONSIDERED THE PROVISIONS OF THIS SECTION 8, AND HAVING DONE SO, AGREES THAT THE COVENANTS SET FORTH HEREIN AND THE REMEDIES AFFORDED THE COMPANY GROUP HEREUNDER ARE FAIR AND REASONABLE AND ARE REASONABLY REQUIRED FOR THE PROTECTION OF THE LEGITIMATE BUSINESS INTERESTS AND GOODWILL OF THE COMPANY GROUP. THE EMPLOYEE UNDERSTANDS THAT THE FOREGOING RESTRICTIONS MAY LIMIT THE EMPLOYEE’S ABILITY TO EARN A LIVELIHOOD IN A BUSINESS SIMILAR TO THE BUSINESS OF THE COMPANY AND ANY OF ITS AFFILIATES, BUT THE EMPLOYEE NEVERTHELESS BELIEVES THAT THE EMPLOYEE HAS RECEIVED AND WILL RECEIVE SUFFICIENT CONSIDERATION AND OTHER BENEFITS AS AN EXECUTIVE OF DocuSign Envelope ID: 9ECAE601-F283-44DF-96B0-37E03A43D927
