This Consulting Agreement (this “Agreement”) is made and entered into as of April 3, 2025 (the “Effective Date”) by and between Sahil Kirpekar, with an address at [●] (“Consultant”),  and atai Life Sciences AG, a German Public Limited Company having a principal place of business at Wallstraße 16, 10179, Berlin, Germany (“atai”). Both atai and Company  may each hereinafter be referred to individually as a “Party”, and collectively as the “Parties”.

Whereas, atai is a global biotechnology company builder which develops innovative treatments that address significant unmet medical needs and lead to paradigm shifts in the mental health space, thereby serving the millions of people globally that suffer from mental health disorders; and

Whereas, Consultant has experience in Business Development; and

Whereas, atai wants to engage Consultant to perform, and Consultant wants to provide, the Services in accordance with this Agreement.

Now, therefore, in consideration of the premises and terms set forth below, and other good and valuable consideration, the sufficiency of which are hereby acknowledged, the Parties agree as follows:

a) Consultant agrees to provide, with the title “Advisor” and in strict accordance with the terms and conditions of this Agreement, such consulting, advisory and related services (the “Services”) as are described in one or more written Statements of Work, substantially in the form of Exhibit A hereto, that are mutually agreed to and executed from time to time by both Parties pursuant to this Agreement (each, a “SOW”). Once executed, a SOW will be attached to and made a part of this Agreement as a sequentially-numbered exhibit (e.g., B-1, B-2, etc.); provided, that, a given SOW (a) governs only the Services described in such SOW, and (b) is subject to the terms and conditions herein unless such SOW expressly and unambiguously indicates the intent of the Parties to include terms that diverge from this Agreement. Unless otherwise stated in an individual SOW, each new SOW shall be considered to supercede and terminate the prior numbered SOW.

b) In the performance of the Services, Consultant shall strictly comply with (x) the applicable SOW including the delivery of any deliverables in accordance with any timelines provided for in such SOW, (y) all federal, state, local, national and international laws, statutes, ordinances, rules, regulations, and codes, applicable to Consultant with regard to the provision of the Services (“Applicable Laws”), and (z) all rules, procedures and standards promulgated from time to time by atai and provided to Consultant with regard to the conduct of Consultant. Consultant shall not infringe on the intellectual property rights of any third party in the performance of the Services.

2.  Invoicing & Compensation; Reimbursement of Costs. In full consideration for the Consultant’s performance of the Services and transfer of intellectual property generated thereby, atai shall pay Consultant such compensation as provided for in the governing SOW (rounded to the nearest quarter hour if provided on an hourly basis or prorated if provided on any other basis), plus, reimburse to Consultant any expenses preapproved by atai in writing which are supported by relevant receipts, itemized separately on the relevant invoice, and consistent with atai’s policy on expense reimbursement. Consultant shall not be entitled to, and hereby waives any interest in and to, any other benefits, coverages or privileges, including without limitation social security, unemployment, medical, disability or pension payments, made available to employees of atai. Consultant’s compensation hereunder is not subject to withholding for foreign, federal, social security, state or local taxes. Consultant understands that the Consultant may be liable for self-employment (e.g., social security and medicare) tax, in accordance with applicable law. The Consultant shall indemnify and hold harmless atai and its directors, officers, employees, agents, consultants and other representatives (collectively, "Representatives") in relation to the payment of all such taxes, including withholding taxes, employee social security, disability, unemployment and any interest and penalties applied thereon. On request, Consultant shall provide proof of timely payment of all such taxes to atai. The Consultant shall, unless otherwise set forth in the applicable SOW, (a) provide atai with an invoice for the Services within the first five (5) business days of each month during the Term for the services and approved expenses applicable to the prior month, and (b) send all such invoices to [●].  Invoices shall include the following details: (a) the date and invoice number of such invoice; (b) the purchase order (PO) number applicable to such invoice; (c) the name of the legal entity providing services (and registration ID number, if applicable); (d) the name of the program for which the Consultant is providing services (where applicable). In the situation that this Agreement covers more than one program, the invoice must specify the amount directed to each program; (e) total invoiced amount, including VAT/sales tax for each item on the invoice; (f) VAT/sales tax IDs and VAT/sales tax status; and (f) the name of the Company Subcontractor or other person(s) providing the services. Consultant shall provide atai with a completed Internal Revenue Service Form W-9 (if located in the United States) or Form W-8 (if located outside the United States) prior to or with delivery of the initial invoice in accordance with this paragraph. Unless expressly set forth in a given SOW, all prices, fees and other charges will be in US dollars, and will include all taxes, including local, state, federal or foreign sales and use taxes, and VAT, if any. All undisputed, invoiced amounts by company check or electronic wire will be made within thirty (30) days following atai’s receipt of Consultant’s invoice. The Parties agree that the payment provided hereunder to Consultant represents fair market value for the Services and transfer of intellectual property and is not in any way dependent on the volume or value of any referrals or business that otherwise may be generated between the Parties.

3.  Independent Contractor; Subcontracting.  Consultant is not, nor shall Consultant be deemed to be at any time during the Term, an employee of atai, or any of its Affiliates; Consultant’s status and relationship with atai shall be that of an independent contractor and consultant, and Consultant will determine the method, means and details of performing the Services, including making themselves reasonably available outside of standard working hours. atai has specifically contracted for Consultant’s Services and therefore, Consultant may not assign, delegate or subcontract Consultant’s obligations under this Agreement, either in whole or in part, without the prior written consent of atai (“Consent”). Nothing in this Agreement shall be construed to give Consultant authority to (a) represent that Consultant is an employee of atai, (b) to bind atai with respect to contracts or any other matters, or (c) to represent atai before any court or government or regulatory authority without the express written authorization of atai. As used herein, the term “Affiliates” shall mean any Person in control of, controlled by or under common control with a Party, or any of its respective subsidiaries, parent companies, or related companies, divisions, predecessors, successors, interests, assigns, and/or entities in which it has an ownership interest, and all Persons acting by, through, under and/or in concert with any of foregoing. As used herein, the term “Person(s)” shall mean any individual, corporation, company, partnership, trust, limited liability company or other entity.

4.  Term of Agreement; Termination.  This Agreement commences on the Effective Date and terminates at 11:59 p.m. EST on the first (1st) anniversary of the Effective Date, unless extended by mutual written consent of the Parties or earlier terminated by either Party in accordance with Section 5 below (the "Term"); provided, however, that if a given SOW is in progress on such anniversary date, the Term will instead expire upon the completion of the Services governed by such SOW. Sections 6 through 13 and 16 through 17 shall survive the termination or expiration of this Agreement for any reason.

5.  Cancellation of Services.  Either Party may terminate this Agreement or any SOW hereunder upon ten (10) days prior written notice to the other Party for any or no reason. Any such termination will be without prejudice to any right or remedy such terminating Party may have due to any failure of the other Party to perform its obligations under this Agreement. In the event of a termination, Consultant shall immediately cease all work, shall comply with its obligations hereunder, including the return of any Confidential Information (as defined herein), and shall be entitled to payment hereunder for Services performed or expenses incurred prior to the effective date of termination. Notwithstanding the foregoing, atai may terminate this Agreement, effective immediately upon written notice, if Consultant breaches or threatens to breach any material provision of this Agreement.

6.  Warranties of Consultant.  Consultant represents and warrants to atai that (a) with respect to any information, know-how, knowledge or data disclosed by Consultant to atai in the performance of this Agreement, Consultant has the full and unrestricted right to disclose the same; (b) Consultant will provide the Services in a professional, diligent and timely manner, in accordance with this Agreement, any reasonable instructions from atai, and all Applicable Laws; (c) Consultant is free to undertake the Services required by this Agreement, and there is, and shall be during the Term, no conflict of interest between Consultant’s performance of this Agreement and any obligation Consultant may have to any third party; and (d) Consultant has, and at all times during the Term will maintain, all professional and/or business licenses and/or registrations required or reasonably expected of Consultant. Subject to the foregoing, Consultant retains the right to contract with third parties for Consultant’s consulting services without restriction.

7. Third-Party Suppliers and Sub-Contractors. Consultant’s services hereunder are personal; accordingly, Consultant shall not, absent Consent, subcontract any portion of the Services to any third party; and, in the event of any such Consent, Consultant shall at all times be responsible for work performed by such third party, as well as such third party’s strict compliance with this Agreement.

8.  Confidentiality. Consultant acknowledges that any use or disclosure of Confidential Information not specifically authorized by atai may cause substantial and irreparable harm to atai or its Affiliates. Consultant shall therefore hold in confidence, and shall not disclose, any Confidential Information except (a) as expressly permitted by this Agreement, or (b) as required by applicable law or legal process, in which instance Consultant shall provide atai with prior written notice of any such disclosure so that atai can seek an appropriate protective order. For the avoidance of doubt, nothing in this Agreement prohibits Consultant from making disclosures to responsible government officials that are required or protected by laws in the United States, and the United States Defend Trade Secrets Act, 18 U.S.C. § 1833(b) may provide immunity to Consultant for certain disclosures of trade secrets to his attorney or to government officials in the United States. Consultant shall use Confidential Information solely to perform the Services and shall not use or exploit such Confidential Information for the benefit of Consultant or any third party without Consent. Consultant shall immediately notify atai of, and shall thereafter assist atai in remedying, any unauthorized use or disclosure of any Confidential Information. Consultant shall not provide any information to atai in violation of the proprietary rights of any third party. The obligations of Consultant pursuant to this Section 8 shall survive the expiration or termination of this Agreement and continue thereafter in perpetuity.

No rights, obligations, representations or terms other than those expressly set forth herein are to be implied from this Agreement; nothing herein shall be construed as granting any right or license to Consultant under any inventions owned or controlled by atai or its Affiliates. The Confidential Information is, and shall remain, the property of atai or its Affiliates. atai makes no express or implied representation or warranty as to the accuracy or completeness of any Confidential Information; the Confidential Information is provided to Consultant “AS IS” and Consultant agrees that it shall not be entitled to rely on the accuracy or completeness of any Confidential Information. Consultant shall, within thirty (30) days of the termination or expiration of this Agreement, return to atai or destroy (at atai’s discretion) all Confidential Information (and any copies thereof), whether in writing or presented, stored or maintained in or by electronic, magnetic or other means; provided, however, that Consultant may retain one (1) copy of the Confidential Information for the sole purpose of monitoring its obligations hereunder.

As used in this Agreement, “Confidential Information” means any information, except to the extent excluded pursuant to this Section 8, whether in written, oral, electronic or other form, disclosed by or on behalf of atai or its Affiliates to the Consultant, or developed by or on behalf of the Consultant in performance of the Services. Confidential Information includes all information and facts concerning this Agreement and the relationship between the Parties, atai’s or its Affiliates’ business plans, customers, future customers, suppliers, licensors, licensees, partners, investors, affiliates, training methods, financial information, sales prospects, client lists, ideas, discoveries, creations, innovations, improvements, know-how, inventions, designs, developments, software, methods, and any other financial, scientific, technical, trade or business secret or confidential or proprietary information of atai. As used herein, the term “trade secrets” will be given its broadest possible interpretation under applicable law. Notwithstanding the foregoing, Confidential Information excludes any information that Consultant can establish by written records: (w) was in Consultant’s possession prior to disclosure hereunder; (x) is or becomes available to the general public through no wrongful act of Consultant; (y) is disclosed to Consultant by a third party having both (i) no duty of confidentiality regarding such information and (ii) the legal right to disclose such information; or (z) has been developed by or for Consultant independently without the use of, and having no access to, the Confidential Information.

9.  Non-Solicitation.  During the Term and for a period of twelve (12) months thereafter (or to the maximum extent permitted by law prior to such time), Consultant shall not, either alone or in association with any third party, (a) solicit, or permit any organization directly or indirectly controlled by Consultant (an “Organization”) to solicit, any employee of atai or its Affiliates to leave the employ of atai or its Affiliates; (b) solicit for employment, hire or engage as an independent contractor, or permit any Organization to solicit for employment, hire or engage as an independent contractor, any person who is employed or engaged by atai or its Affiliates during the Term; and/or (c) solicit, divert or take away, the business or patronage of any clients, customers or accounts, or prospective clients, customers or accounts, of atai or its Affiliates that were contacted, solicited or served by Consultant on behalf of atai during the Term. Notwithstanding the foregoing, Consultant is not prohibited from engaging in any general solicitations, so long as such solicitation does not specifically target any of the individuals who are then employed by atai or its Affiliates.

10.  Effect of Breach.  Consultant acknowledges and agrees that a breach of any of the restrictive covenants contained in Sections 7 (Third-Party Suppliers and Sub-Contractors), 8 (Confidentiality), 9 (Non-Solicitation) or 11 (Ownership of Inventions) (collectively, the “Restrictive Covenants”) would cause irreparable injury to atai and that remedies at law of atai for any material breach of such covenants would be inadequate; therefore, atai shall be entitled to specific performance of the Restrictive Covenants or injunctive relief against activities in violation of the Restrictive Covenants, or both, but such relief shall not diminish the right of atai to claim and recover damages against Consultant for any breach of the Restrictive Covenants in addition thereto. Consultant acknowledges and represents that it has obtained its own independent legal advice regarding the matters contained in this Agreement, and that Consultant has not relied on any representation by atai or its attorneys not expressly stated herein.

The Consultant and atai agree that, to the extent that any atai Inventions include any work of authorship that qualifies as a ‘work made for hire’ as defined by U.S. copyright law, atai owns such work of authorship as a work made for hire thereunder. Consultant shall maintain complete and accurate Records of all atai Inventions, including any Records necessary to document conception and/or reduction to practice of any atai Inventions. Upon atai’s request, and at atai’s expense, Consultant shall perform all acts, including the execution of all documents, deemed necessary or desirable by atai in applying for, obtaining, perfecting and enforcing IP Rights worldwide (all such acts, collectively, “Advancing IP Rights”); if atai is unable for any reason to secure Consultant’s for any such document, the Consultant hereby irrevocably designates and appoints any officer of atai as Consultant’s attorney-in-fact to take any and all lawfully permitted acts directed to Advancing IP Rights, all with the same legal force and effect as if taken by Consultant.

Subject to the foregoing Incorporated IP license, Consultant has exclusive ownership of all Consultant Inventions.
