SERVICES AGREEMENT

This Agreement is entered into August 1, 2021 between Signature Analytics LLC (“SA”) and MediciNova, Inc. (“Client”) located at 4275 Executive Square, Suite 300, La Jolla, CA 92037.

1. Services. During the term of this Agreement, SA will provide financial and accounting services (“Services”) as agreed from time to time by Client and SA. All such Services shall be performed by SA and its agents in conformity with the highest professional and ethical standards generally accepted as applicable to such Services. The term of this Agreement will be one year with automatic annual renewals. However, Client or SA may terminate this Agreement at any time by giving at least thirty (30) days’ prior written notice. Any notices under this Agreement may be delivered by hand, email, U.S. mail or courier. SA has the sole discretion to place and remove the Service Providers (as defined in Appendix A) working with Client. SA will report and pay any income tax withholdings, disability, unemployment, workers’ compensation, employee benefits, and similar items for its employees. Fees and Hourly Rates of the Service Providers are stated in the attached Appendix A, which is included as part of this Agreement.

2. Nondisclosure. SA shall only use and/or disclose Client’s financial data and records (“Confidential Information”) as reasonably necessary for the purposes of this Agreement. This restriction will not apply to information that (a) is already known by SA at the time of receipt; (b) becomes publicly known through no wrongful act of SA; (c) is rightfully received from a third party without obligation of confidentiality; or (d) is required to be disclosed by applicable law.

3. On-Site Representatives. If any Service Provider of SA is required to go on-site to the offices of Client, Client agrees to follow all government guidelines pertaining to COVID-19 safety. If the Service Provider does not feel safe from COVID-19 on-site, or at the instruction of SA, that person may immediately leave, which shall not constitute a breach of this Agreement. The parties shall then work promptly and in good faith to determine a reasonable solution.

4. Placement. During the term of this Agreement and for 6 months thereafter, if Client directly or indirectly hires any Service Provider assigned to Client, either as a full-time or part-time employee or independent contractor, it is agreed Client will pay SA the following placement fee(s): CFO, VP of Accounting and Process, and Chief Accounting Officer $85,000; Controller and Director of Process Implementation $60,000; Accounting Manager $40,000; Senior Accountant $25,000; and Staff Accountant and Bookkeeper $20,000. Client acknowledges that if Client hires any of the Service Providers: (a) SA invested substantial time and money to locate, hire and train its Service Providers, and SA will be required to do so again, (b) each of SA’s Service Providers perform similar, concurrent services for multiple SA clients, so SA will be required to cover its other clients, and (c) the unique nature of SA’s business model creates additional risks and costs. Therefore, Client and SA agree these fees accurately reflect the reasonable value of SA’s time, costs and other financial considerations.

5. Limiting Conditions. All Services will be subject to the following conditions: (a) all statements, communications, results, reviews, reports and other deliverables provided by SA as part of the Services (collectively, “SA Reports”) will be solely for the use of Client, including for purposes of Client’s disclosure and reporting obligations under the Securities Act of 1933 and the Securities Exchange Act of 1934, in each case as amended (the “Acts”), the rules and regulations under the Acts and Client’s obligations as the issuer of securities on one or more stock exchanges; (b) information in the SA Reports may not be modified in any way except by SA; (c) SA will not express an opinion or any other form of assurance regarding the Client’s financial statements or otherwise, and no SA Reports should be interpreted as such; (d) the Services will not be provided as Certified Public Accountant services; (e) the Services will not include any financial audit or audit of financial statements, nor may SA’s name be used in association with any audit; (f) the SA Reports may not be relied upon to discover errors, fraud or illegal acts, but if SA discovers any such matters, SA will use reasonable efforts to bring them to Client’s attention; and (g) Client’s management shall be solely responsible for internal controls, legal compliance, accuracy of financial statements, information and data, conformity with GAAP, and the review of all SA Reports before they are used or relied upon.
