 ATAI LIFE SCIENCES AG 

STOCK OPTION AGREEMENT- INCORPORATED TERMS AND CONDITIONS 

AGREEMENT made as of the date of grant set forth in the Stock Option Grant Notice by and between ATAI Life Sciences AG, a German stock
corporation and any successor corporation under the terms of the Plan (the “Company”), and the individual whose name appears on the Stock Option Grant Notice (the “Participant”). 

WHEREAS, the Company desires to grant to the Participant an Option to purchase shares of its Common Stock, under and for the purposes set
forth in the Company’s 2020 Employee, Director and Consultant Equity Incentive Plan (the “Plan”); 
 WHEREAS, the Company and
the Participant understand and agree that any terms used and not defined herein have the same meanings as in the Plan; and 
 WHEREAS, the
Company and the Participant each intend that the Option granted herein shall be of the type set forth in the Stock Option Grant Notice. 

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth and for other good and valuable consideration, the parties
hereto agree as follows: 
 1. GRANT OF OPTION. 

The Company hereby grants to the Participant the right and option to purchase all or any part of an aggregate of the number of Shares set forth
in the Stock Option Grant Notice, on the terms and conditions and subject to all the limitations set forth herein and in the Plan, which is incorporated herein by reference, and subject to applicable securities laws. The Participant acknowledges
receipt of a copy of the Plan. 
 2. EXERCISE PRICE. 

The exercise price of the Shares covered by the Option shall be the amount per Share set forth in the Stock Option Grant Notice, subject to
adjustment, as provided in the Plan, in the event of a stock split, reverse stock split or other events affecting the holders of Shares after the date hereof (the “Exercise Price”). Payment shall be made in accordance with Paragraph 9 of
the Plan. 
 3. EXERCISABILITY OF OPTION. 

Subject to the terms and conditions set forth in this Agreement and the Plan, the Option granted hereby shall become vested and exercisable as
set forth in the Stock Option Grant Notice and is subject to the other terms and conditions of this Agreement and the Plan. 

  
  

 













 4. TERM OF OPTION. 

This Option shall terminate on the Option Expiration Date as specified in the Stock Option Grant Notice and, if this Option is designated in
the Stock Option Grant Notice as 
 an ISO and the Participant owns as of the date hereof more than 10% of the total combined voting power of all classes of
capital stock of the Company or an Affiliate, such date may not be more than five3 years from the date of this Agreement, but shall be subject to earlier termination as provided herein or in the
Plan. 
 If the Participant ceases to be an Employee, Director or Consultant of the Company or of an Affiliate for any reason other than the
death or Disability of the Participant, or termination of the Participant for Cause (the “Termination Date”), the Option to the extent then vested and exercisable pursuant to Section 3 hereof as of the Termination Date, and not
previously terminated in accordance with this Agreement, may be exercised within three (3)4 months after the Termination Date, or on or prior to the Option Expiration Date as specified in
the Stock Option Grant Notice, whichever is earlier, but may not be exercised thereafter except as set forth below. In such event, the unvested portion of the Option shall not be exercisable and shall expire and be cancelled on the Termination Date.

 If this Option is designated in the Stock Option Grant Notice as an ISO and the Participant ceases to be an Employee of the Company or of
an Affiliate but continues after termination of employment to provide service to the Company or an Affiliate as a Director or Consultant, this Option shall continue to vest in accordance with Section 3 above as if this Option had not terminated
until the Participant is no longer providing services to the Company. In such case, this Option shall automatically convert and be deemed a Non-Qualified Option as of the date that is three (3) months
from termination of the Participant’s employment and this Option shall continue on the same terms and conditions set forth herein until such Participant is no longer providing service to the Company or an Affiliate. 

Notwithstanding the foregoing, in the event of the Participant’s death within three (3) months after the Termination Date, the
Participant’s Survivors may exercise the Option within one (1) year after the Termination Date, but in no event after the Option Expiration Date as specified in the Stock Option Grant Notice, and this Option shall thereupon terminate. 

In the event the Participant’s service is terminated by the Company or an Affiliate for Cause, the Participant’s right to exercise
any unexercised portion of this Option even if vested shall cease immediately as of the time the Participant is notified his or her service is terminated for Cause, and this Option shall thereupon terminate. Notwithstanding anything herein to the
contrary, if subsequent to the Participant’s termination, but prior to the exercise of the Option, the Administrator determines that, either prior or subsequent to the Participant’s termination, the Participant engaged in conduct which
would constitute Cause, then the Participant shall immediately cease to have any right to exercise the Option and this Option shall thereupon terminate. 

In the event of the Disability of the Participant while an Employee, Director or Consultant of the Company or of an Affiliate, as determined
in accordance with the Plan, the Option shall be exercisable within one (1) year after the Participant’s termination of service due 
  

 
 3 Under the ISO rules, five years is the maximum term for an ISO grant to a greater than 10% stockholder. 

4 Three months is the maximum time period for an ISO. If the time period is longer, any option exercised
more than three months after the individual ceases to be an Employee of the company shall be deemed pursuant to the Code to be a non-qualified stock option. 

  
 2 

 
  













 to Disability or, if earlier, on or prior to the Option Expiration Date as specified in the Stock Option
Grant Notice. In such event, the Option shall be fully vested and exercisable. 
 In the event of the death of the Participant while an
Employee, Director or Consultant of the Company or of an Affiliate, the Option shall be exercisable by the Participant’s Survivors within one (1) year after the date of death of the Participant or, if earlier, on or prior to the Option
Expiration Date as specified in the Stock Option Grant Notice. In such event, the Option shall be fully vested and exercisable. 
 5.
METHOD OF EXERCISING OPTION. 
 Subject to the terms and conditions of this Agreement, the Option may be exercised by notice in text
form (sec. 126b of the German Civil Code) to the Company or its designee, in substantially the form of Exhibit A attached hereto (or in such other form acceptable to the Company, which may include electronic notice) (“Notice of
Exercise”). Such notice shall state the number of Shares with respect to which the Option is being exercised and shall be signed by the person exercising the Option (which signature may be provided electronically in a form acceptable to the
Company). Payment of the Exercise Price for such Shares shall be made in accordance with Paragraph 9 of the Plan. The Company shall deliver such Shares as soon as practicable after the notice shall be received, provided, however, that the Company
may delay issuance of such Shares (i) until completion of any action or obtaining of any consent, which the Company deems necessary under any applicable law (including, without limitation, foreign securities laws, United States state securities
or “blue sky” laws) and (ii) in order to minimize the cost and effort of the issuance and delivery of the Shares (e.g. by combining several deliveries of shares), but only for a reasonable time, which may not exceed a period of three
months. The Shares as to which the Option shall have been so exercised shall be delivered as provided above to or upon the order of the person exercising the Option. In the event the Option shall be exercised, pursuant to Section 4 hereof, by
any person other than the Participant, such notice shall be accompanied by appropriate proof of the right of such person to exercise the Option. All Shares that shall be purchased upon the exercise of the Option as provided herein shall be fully
paid and nonassessable. 
 6. PARTIAL EXERCISE. 

Exercise of this Option to the extent above stated may be made in part at any time and from time to time within the above limits, except that
no fractional share shall be issued pursuant to this Option. 
 7. NON-ASSIGNABILITY. 

The Option shall not be transferable by the Participant otherwise than by will or by the laws of descent and distribution. In relation to U.S.
Taxpayers, if this Option is a Non-Qualified Option then it may also be transferred pursuant to a qualified domestic relations order as defined by the U.S. Code or Title I of the U.S. Employee Retirement
Income Security Act or the rules thereunder. Except as provided above in this paragraph, the Option shall be exercisable, during the Participant’s lifetime, only by the Participant (or, in the event of legal incapacity or incompetency, by the
Participant’s guardian or representative) and shall not be 

  
 3 

 
  













 assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be
subject to execution, attachment or similar process. Any attempted transfer, assignment, pledge, hypothecation or other disposition of the Option or of any rights granted hereunder contrary to the provisions of this Section 7, or the levy of
any attachment or similar process upon the Option shall be null and void. 
 8. NO RIGHTS AS STOCKHOLDER UNTIL EXERCISE. 

The Participant shall have no rights as a stockholder in the Company with respect to Shares subject to this Agreement until issuance of the
Shares as set forth in this Agreement and tender of the purchase price for the Shares being purchased. Except as is expressly provided in the Plan with respect to certain changes in the capitalization of the Company, no adjustment shall be made for
dividends or similar rights for which the record date is prior to the date of such registration. 
 9. ADJUSTMENTS. 

The Plan contains provisions covering the treatment of Options in a number of contingencies such as stock splits and mergers. For the avoidance
of doubt, provisions in the Plan for adjustment with respect to stock subject to Options and the related provisions with respect to successors to the business of the Company are hereby made applicable hereunder and are incorporated herein by
reference. 
 10. TAXES; USE OF PROFESSIONAL ADVISORS; ADVICE MADE BY THE COMPANY; DISCLAIMER OF LIABILITY. 

The Participant acknowledges and agrees that (i) any income or other taxes due from the Participant with respect to this Option or the
Shares issuable upon exercise of this Option shall be the Participant’s responsibility to the extent permitted by applicable law; (ii) the Participant was free to use professional advisors of his or her choice in connection with the
execution of this Agreement, has received advice from his or her professional advisors in connection with the execution of this Agreement, understands its meaning and import, and is entering into this Agreement freely and without coercion or duress;
(iii) the Participant has not received and is not relying upon any advice, representations or assurances made by or on behalf of the Company or any Affiliate or any Employee of or legal counsel to the Company or any Affiliate regarding any tax
or other effects or implications of the Option, the Shares or other matters contemplated by this Agreement and (iv) to the extent permitted by applicable law and except for liability of the Company for intend or gross negligence, neither the
Administrator, the Company, its Affiliates, nor any of its officers or directors, shall be held liable for any applicable costs, taxes, or penalties associated with the Option if, in fact, the Internal Revenue Service were to determine that the
Option constitutes deferred compensation under Section 409A of the U.S. Code. 
 If this Option is designated in the Stock Option Grant
Notice as a Non-Qualified Option or if the Option is an ISO and is converted into a Non-Qualified Option and such Non-Qualified
Option is exercised, the Participant agrees that the Company, or any Affiliate of the Company which employs or employed the Participant, may withhold from the Participant’s 

  
 4 

 
  













 remuneration, if any, up to the maximum statutory amount of foreign, United States federal, state and local
withholding taxes attributable to such amount that is considered compensation includable in such person’s gross income. At the Company’s discretion, the amount required to be withheld may be withheld in cash from such remuneration, or in
kind from the Shares otherwise deliverable to the Participant on exercise of the Option. The Participant further agrees that, if the Company, or any Affiliate of the Company which employs or employed the Participant, does not withhold an amount from
the Participant’s remuneration sufficient to satisfy the Company’s income tax withholding obligation, the Participant will reimburse the Company, or any Affiliate of the Company which employs or employed the Participant, on demand, in
cash, for the amount under-withheld. 
 11. PURCHASE FOR INVESTMENT. 

Unless the offering and sale of the Shares to be issued upon the particular exercise of the Option shall have been effectively registered under
the U.S. Securities Act of 1933, as now in force or hereafter amended (the “Securities Act”), the Company shall be under no obligation to issue the Shares covered by such exercise unless the Company has determined that such exercise and
issuance would be exempt from the registration requirements of the Securities Act and until the following conditions have been, to the extent permitted under applicable law, fulfilled: 

 

	 	(a)	 The person(s) who exercise the Option shall warrant to the Company, at the time of such exercise, that such
person(s) are acquiring such Shares for their own respective accounts, for investment, and not with a view to, or for sale in connection with, the distribution of any such Shares, in which event the person(s) acquiring such Shares shall be bound by
the provisions of the following legend which shall be endorsed upon any certificate(s) evidencing the Shares issued pursuant to such exercise: 



“The shares represented by this certificate have been taken for investment and they may not be sold or otherwise transferred by any
person, including a pledgee, unless (1) either (a) a Registration Statement with respect to such shares shall be effective under the United States Securities Act of 1933, as amended, or (b) the Company shall have received an opinion of
legal counsel satisfactory to it that an exemption from registration under such Act is then available, and (2) there shall have been compliance with all applicable United States state securities laws;” and 

 

	 	(b)	 If the Company so requires, the Company shall have received an opinion of its legal counsel that the Shares may
be issued upon such particular exercise in compliance with the Securities Act without registration thereunder. Without limiting the generality of the foregoing, the Company may delay issuance of the Shares (i) until completion of any action or
obtaining of any consent, which the Company deems necessary under any applicable law (including without limitation United States state securities or “blue sky” laws) and (ii) in order to minimize the cost and effort of the issuance
and delivery of the Shares (e.g. by combining several deliveries of shares.

 12. RESTRICTIONS ON TRANSFER OF SHARES; REPURCHASE OF SHARES. 

12.1 The Shares acquired by the Participant pursuant to the exercise of the Option granted hereby shall not be transferred by the Participant
except as permitted herein or as required in the Notice of Exercise attached as Exhibit A hereto. 
 12.2 In the event of the
Participant’s termination of service for any reason, the Company shall have, to the extent permitted by applicable law, the option, but not the obligation, to repurchase all or any part of the Shares issued pursuant to this Agreement
(including, without limitation, Shares purchased after termination of service, Disability or death in accordance with Section 4 hereof). In the event the Company does not, upon the termination of service of the Participant (as described above),
exercise its option pursuant to this Section 12.2, the restrictions set forth in the balance of this Agreement shall not thereby lapse, and the Participant for himself or herself, his or her heirs, legatees, executors, administrators and other
successors in interest, agrees that the Shares shall remain subject to such restrictions. The following provisions shall apply to a repurchase under this Section 12.2: 
  

	 	(i)	 The per share repurchase price of the Shares to be sold to the Company upon exercise of its option under this
Section 12.2 shall be equal to the Fair Market Value of each such Share determined in accordance with the Plan as of the date of repurchase provided, however, in the event of a termination by the Company for Cause, the per share repurchase
price of the Shares to be sold to the Company upon exercise of its option under this Section 12.2 shall be equal to the lesser of the Exercise Price and the Fair Market Value on the date of the repurchase. 



 

	 	(ii)	 The Company’s option to repurchase the Participant’s Shares in the event of termination of service
shall be valid for a period of 12 months commencing with the date of such termination of service. 


  

	 	(iii)	 In the event the Company shall be entitled to and shall elect to exercise its option to repurchase the
Participant’s Shares under this Section 12.2, the Company shall notify the Participant, or in case of death, his or her Survivor, in writing of its intent to repurchase the Shares. Such written notice may be mailed or sent by email by the
Company up to and including the last day of the time period provided for in Section 12.2(ii) above for exercise of the Company’s option to repurchase. 



(iv) The notice to the Participant shall specify the address at, and the time and date on, which payment of the repurchase price is to be made
(the “Closing”). The date specified shall not be less than ten (10) days nor more than sixty (60) days from the date of the mailing of the notice, and the Participant or his or her successor in interest with respect to the Shares
shall have no further rights as the owner thereof from and after the date specified in the notice. At the Closing, the repurchase price shall be delivered to the Participant or his or her successor in interest and the Shares being purchased, duly
endorsed for transfer, shall, to the extent that they are not then in the possession of the Company, be delivered to the Company by the Participant or his or her successor in interest. 

  
 6 

 
  













 12.3 To the extent permitted by applicable law, it shall be a condition precedent to the
validity of any sale or other transfer of any Shares by the Participant that the following restrictions be complied with (except as otherwise provided in this Section 12) or in the Notice of Exercise: 

 

	 	(i)	 No Shares owned by the Participant may be sold, pledged or otherwise transferred (including by gift or devise)
to any person or entity, voluntarily, or by operation of law, except in accordance with the terms and conditions hereinafter set forth. 


  

	 	(ii)	 Before selling or otherwise transferring all or part of the Shares, the Participant shall give notice in text
form (sec. 126b of the German Civil Code) of such intention to the Company, which notice shall include the name of the proposed transferee, the proposed purchase price per share, the terms of payment of such purchase price and all other matters
relating to such sale or transfer and shall be accompanied by a copy of the binding written agreement of the proposed transferee to purchase the Shares of the Participant. Such notice shall constitute a binding offer by the Participant to sell to
the Company such number of the Shares then held by the Participant as are proposed to be sold in the notice at the monetary price per share designated in such notice, payable on the terms offered to the Participant by the proposed transferee
(provided, however, that the Company shall not be required to meet any non-monetary terms of the proposed transfer, including, without limitation, delivery of other securities in exchange for the Shares
proposed to be sold). The Company shall give written notice to the Participant as to whether such offer has been accepted in whole by the Company within sixty (60) days after its receipt of notice from the Participant. The Company may only
accept such offer in whole and may not accept such offer in part. Such acceptance notice shall fix a time, location and date for the Closing on such purchase (“Closing Date”) which shall not be less than ten (10) nor more than sixty
(60) days after the giving of the acceptance notice, provided, however, if any of the Shares to be sold pursuant to this Section 12.3 have been held by the Participant for less than six (6) months, then the Closing Date may be
extended by the Company until no more than ten (10) days after such Shares have been held by the Participant for six (6) months if required under applicable accounting rules in effect at the time. The place for such Closing shall be at the
Company’s principal office. At such Closing, the Participant shall accept payment as set forth herein and shall deliver to the Company in exchange therefor certificates for the number of Shares stated in the notice accompanied by duly executed
instruments of transfer. 



  
 7 

 
  














	 	(iii)	 If the Company shall fail to accept any such offer, the Participant shall be free to sell all, but not less
than all, of the Shares set forth in his or her notice to the designated transferee at the price and terms designated in the Participant’s notice, provided that (i) such sale is consummated within six (6) months after the giving of notice
by the Participant to the Company as aforesaid, and (ii) the transferee first agrees in text form (sec. 126b of the German Civil Code) to be bound by the provisions of this Section 12 so that such transferee (and all subsequent
transferees) shall thereafter only be permitted to sell or transfer the Shares in accordance with the terms hereof, and the Company’s right of repurchase set forth in Section 12.2 above shall continue in accordance with its terms. After
the expiration of such six (6) months, the provisions of this Section 12.3 shall again apply with respect to any proposed voluntary transfer of the Participant’s Shares. 



 

	 	(iv)	 The restrictions on transfer contained in this Section 12.3 shall not apply to (a) transfers by the
Participant to his or her spouse or children or to a trust for the benefit of his or her spouse or children, (b) transfers by the Participant to his or her guardian or conservator, and (c) transfers by the Participant, in the event of his
or her death, to his or her executor(s) or administrator(s) or to trustee(s) under his or her will (collectively, “Permitted Transferees”); provided however, that in any such event the Shares so transferred in the hands of each such
Permitted Transferee shall remain subject to this Agreement, and each such Permitted Transferee shall so acknowledge in text form (sec. 126b of the German Civil Code) as a condition precedent to the effectiveness of such transfer.



  

	 	(v)	 The provisions of this Section 12.3 may be waived by the Company. Any such waiver may be unconditional or
based upon such conditions as the Company may impose. 


 12.4 To the extent permitted by applicable law, in the event that
the Participant or his or her successor in interest fails to deliver the Shares to be repurchased by the Company under this Agreement, the Company may elect (a) to establish a segregated account in the amount of the repurchase price, such
account to be turned over to the Participant or his or her successor in interest upon delivery of such Shares, and (b) immediately to take such action as is appropriate to transfer record title of such Shares from the Participant to the Company
and to treat the Participant and such Shares in all respects as if delivery of such Shares had been made as required by this Agreement. The Participant hereby irrevocably grants the Company a power of attorney which shall be coupled with an interest
for the purpose of effectuating the preceding sentence. 
 12.5 To the extent permitted by applicable law, in the event that (i) the
Management Board and (ii) the holders of a majority of the then outstanding shares of Common Stock approve a Sale of the Company (as defined below), specifying that this Section 12.5 shall apply then the 

  
 8 

 
  













 Participant hereby agrees as follows with respect to the Shares and any other equity securities of the
Company which the Participant holds or otherwise exercises dispositive power (the “Drag Along Shares”): 
  

	 	(i)	 in the event such Sale of the Company requires the approval of stockholders, (1) if the matter is to be
brought to a vote at a stockholder meeting, after receiving proper notice of any meeting of stockholders of the Company to vote on the approval of a Sale of the Company, to be present, in person or by proxy, as a holder of Shares, at all such
meetings and be counted for the purposes of determining the presence of a quorum at such meetings; and (2) to vote (in person, by proxy or by action by written consent, as applicable) all Shares in favor of such Sale of the Company and in
opposition of any and all other proposals that could reasonably be expected to delay or impair the ability of the Company to consummate such Sale of the Company; 



 

	 	(ii)	 to refrain from exercising any dissenters’ rights or rights of appraisal under applicable law at any time
with respect to such Sale of the Company; and 


  

	 	(iii)	 to sell to such third party on the terms offered by such third party the Drag Along Shares, or if the Approved
Sale involves less than all of the outstanding capital stock of the Company, the Participant’s pro rata share of the Drag Along Shares, and to execute and deliver all related documentation and take such other action in support of the Sale of
the Company as shall reasonably be requested by the Company. 


 As used herein, the following terms shall have the following respective
meanings: 
 “Fully Diluted Common Shares” means, as of any calculation date, all shares of the Common Stock of the Company then
outstanding, determined on an as-converted basis (and including, for this purpose, any and all shares of Common Stock issued or issuable upon conversion of the Company’s convertible preferred stock, but
specifically excluding, for this purpose, any then outstanding options and warrants). 
 “Sale of the Company” means: 

 

	 	(i)	 a merger or consolidation in which (A) the Company is a constituent party or (B) a subsidiary of the
Company is a constituent party and the Company issues shares of its capital stock pursuant to such merger or consolidation, except any such merger or consolidation involving the Company or a subsidiary in which the shares of capital stock of the
Company outstanding immediately prior to such merger or consolidation continue to represent, or are converted into or exchanged for shares of capital stock that represent, immediately following such merger or consolidation, at least a majority, by
voting power, of the capital stock of (1) the surviving or resulting corporation or (2) if the surviving or 



  
 9 

 
  













 resulting corporation is a wholly owned subsidiary of another corporation immediately
following such merger or consolidation, the parent corporation of such surviving or resulting corporation (provided that, for the purpose of this clause (i) all shares of Common Stock issuable upon exercise of options or warrants outstanding
immediately prior to such merger or consolidation or upon conversion of convertible securities immediately prior to such merger or consolidation shall be deemed to be outstanding immediately prior to such merger or consolidation and, if applicable,
converted or exchanged in such merger or consolidation on the same terms as the actual outstanding shares of Common Stock are converted or exchanged); 
  

	 	(ii)	 the sale, lease, transfer, exclusive license, or other disposition, in a single transaction or series of
related transactions, by the Company or any subsidiary of the Company of all or substantially all the assets of the Company and its subsidiaries taken as a whole, or the sale or disposition (whether by merger or otherwise) of one or more
subsidiaries of the Company if substantially all of the assets of the Company and its subsidiaries taken as a whole are held by such subsidiary or subsidiaries, except where such sale, lease, transfer, exclusive license or other disposition is to a
wholly owned subsidiary of the Company; or 


  

	 	(iii)	 any transaction or series of related transactions to which the Company is a party in which in excess of fifty
percent (50%) of the Company’s voting power is transferred such that the stockholders of the Company immediately prior to the transaction or series of related transactions do not own a majority of the voting power of the surviving or acquiring
entity following such transaction or series of transactions; other than any transaction or series of transactions principally for bona fide equity financing purposes in which cash is received by the Company or any successor or indebtedness of the
Company is cancelled or converted or a combination thereof. 


 12.6 If the Company shall pay a stock dividend or declare a
stock split on or with respect to any of its Common Stock, or otherwise distribute securities of the Company to the holders of its Common Stock, the number of shares of stock or other securities of the Company issued with respect to the shares then
subject to the restrictions contained in this Agreement shall be added to the Shares subject to the Company’s rights to repurchase pursuant to this Agreement. If the Company shall distribute to its stockholders shares of stock of another
corporation or equity in another entity, the shares of stock of such other corporation or equity in such other entity, distributed with respect to the Shares then subject to the restrictions contained in this Agreement, shall be added to the Shares
subject to the Company’s rights to repurchase pursuant to this Agreement. 

  
 10 

 
  













 12.7 If the outstanding shares of Common Stock of the Company shall be subdivided into a
greater number of shares or combined into a smaller number of shares, or in the event of a reclassification of the outstanding shares of Common Stock of the Company, or if the Company 

shall be a party to a merger, consolidation or capital reorganization, there shall be substituted for the Shares then subject to the restrictions contained in
this Agreement such amount and kind of securities as are issued in such subdivision, combination, reclassification, merger, consolidation or capital reorganization in respect of the Shares subject immediately prior thereto to the Company’s
rights to repurchase pursuant to this Agreement. 
 12.8 The Company shall not be required to transfer any Shares on its books which shall
have been sold, assigned or otherwise transferred in violation of this Agreement, or to treat as owner of such Shares, or to accord the right to vote as such owner or to pay dividends to, any person or organization to which any such Shares shall
have been so sold, assigned or otherwise transferred, in violation of this Agreement. 
 12.9 The provisions of Sections 12.1, 12.2 and 12.3
shall terminate upon the effective date of the registration of the Shares pursuant to the United States Securities Exchange Act of 1934,or as otherwise approved by the Administrator. 

12.10 To the extent permitted by applicable law, the Participant agrees that, in the event the Company proposes to offer for sale to the public
any of its equity securities and such Participant is requested by the Company and any underwriter engaged by the Company in connection with such offering to sign an agreement restricting the sale or other transfer of Shares, then it will promptly
sign such agreement and will not transfer, whether in privately negotiated transactions or to the public in open market transactions or otherwise, any Shares or other securities of the Company held by him or her during such period as is determined
by the Company and the underwriters, not to exceed 180 days following the closing of the offering, plus such additional period of time as may be required to comply with FINRA Rules or similar rules promulgated by another regulatory authority (such
period, the “Lock-Up Period”). Such agreement shall be in writing and in form and substance reasonably satisfactory to the Company and such underwriter and pursuant to customary and prevailing terms
and conditions. Notwithstanding whether the Participant has signed such an agreement, the Company may impose stop-transfer instructions with respect to the Shares or other securities of the Company subject to the foregoing restrictions until the end
of the Lock-Up Period. 
 12.11 The Participant acknowledges and agrees that, without prejudice to
(any) rights of the Participant as a shareholder of the Company (especially in accordance with sec. 131 of the German Stock Corporation Act), neither the Company, its shareholders nor its directors and officers, has any duty or obligation to
disclose to the Participant any material information regarding the business of the Company or affecting the value of the Shares before, at the time of, or following a termination of the service of the Participant by the Company or any Affiliate,
including, without limitation, any information concerning plans for the Company to make a public offering of its securities or to be acquired by or merged with or into another firm or entity. 

13. NO OBLIGATION TO MAINTAIN RELATIONSHIP; NO RIGHT AND NO PREDJUDICE TO RECEIVE FUTURE GRANTS OF OPTIONS; OPTIONS AS EXTRAORDENARY ITEM OF
COMPENSATION. 

  
 11 

 
  













 The Participant acknowledges that: (i) the Company is not by the Plan or this Option
Agreement obligated to continue the Participant as an Employee, Director or Consultant of the Company or an Affiliate; (ii) the Plan is discretionary in nature and may be suspended or terminated by the Company at any time; (iii) the grant
of the Option is a one-time benefit which does not create any contractual or other right to receive future grants of options, or benefits in lieu of options; (iv) all determinations with respect to any
such future grants, including, but not limited to, the times when options shall be granted, the number of shares subject to each option, the option price, and the time or times when each option shall be exercisable, will be at the sole discretion of
the Company; (v) the Participant’s participation in the Plan is voluntary; (vi) the value of the Option is an extraordinary item of compensation which is outside the scope of the Participant’s employment or consulting contract,
if any; and (vii) the Option is not part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar
payments. 
 14. IF OPTION IS INTENDED TO BE AN ISO. 

If this Option is designated in the Stock Option Grant Notice as an ISO so that the Participant (or the Participant’s Survivors) may
qualify for the favorable tax treatment provided to holders of Options that meet the standards of Section 422 of the U.S. Code then any provision of this Agreement or the Plan which conflicts with the U.S. Code so that this Option would not be
deemed an ISO is, to the extent permitted by applicable law, null and void and any ambiguities shall be resolved so that the Option qualifies as an ISO. The Participant should consult with the Participant’s own tax advisors regarding the tax
effects of the Option and the requirements necessary to obtain favorable tax treatment under Section 422 of the U.S. Code, including, but not limited to, holding period requirements. 

Notwithstanding the foregoing, to the extent that the Option is designated in the Stock Option Grant Notice as an ISO and is not deemed to be
an ISO pursuant to Section 422(d) of the U.S. Code because the aggregate Fair Market Value (determined as of the Date of Option Grant) of any of the Shares with respect to which this ISO is granted becomes exercisable for the first time during
any calendar year in excess of $100,000, the portion of the Option representing such excess value shall be treated as a Non-Qualified Option and the Participant shall be deemed to have taxable income measured
by the difference between the then Fair Market Value of the Shares received upon exercise and the price paid for such Shares pursuant to this Agreement. 

Neither the Company nor any Affiliate shall have any liability to the Participant, or any other party, if the Option (or any part thereof)
that is intended to be an ISO is not an ISO or for any action taken by the Administrator, including without limitation the conversion of an ISO to a Non-Qualified Option; this does not apply in case of
liability of the Company for intent or gross negligence. 
 15. NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION OF AN ISO. 

If this Option is designated in the Stock Option Grant Notice as an ISO then the Participant agrees to notify the Company upon request in text
form (sec. 126b of the German Civil Code) immediately after the Participant makes a Disqualifying Disposition of any of the Shares acquired pursuant to the exercise of the ISO. A Disqualifying Disposition is defined in Section 424(c) of the
U.S. Code and includes any disposition (including any sale) of such Shares 
 before the later of (a) two years after the date the Participant was
granted the ISO or (b) one year after the date the Participant acquired Shares by exercising the ISO, except as otherwise provided in Section 424(c) of the U. S. Code. If the Participant has died before the Shares are sold, these holding
period requirements do not apply and no Disqualifying Disposition can occur thereafter.

 Exhibit A 

NOTICE OF EXERCISE OF STOCK OPTION 

[Form for Unregistered Shares] 
  

	To:	 ATAI Life Sciences AG 



Ladies and Gentlemen: 
 I hereby exercise my
Stock Option to purchase ___ shares (the “Shares”) of the common stock, with no par value, of ATAI Life Sciences AG, a German stock corporation (the “Company”), at the exercise price of $[_____] per share, pursuant to and subject
to the terms of that certain Stock Option Agreement between the undersigned and the Company dated ______. 
 I am aware that the Shares have
not been registered under the United States Securities Act of 1933, as amended (the “Securities Act”), or any United States state securities laws. I understand that the reliance by the Company on exemptions under the Securities Act is
predicated in part upon the truth and accuracy of the statements by me in this Notice of Exercise. 
 I hereby represent and warrant that
(1) I have been furnished with all information which I deem necessary to evaluate the merits and risks of the purchase of the Shares; (2) I have had the opportunity to ask questions concerning the Shares and the Company and all questions
posed have been answered to my satisfaction; (3) I have been given the opportunity to obtain any additional information I deem necessary to verify the accuracy of any information obtained concerning the Shares and the Company; and (4) I
have such knowledge and experience in financial and business matters that I am able to evaluate the merits and risks of purchasing the Shares and to make an informed investment decision relating thereto. 

I hereby represent and warrant that I am purchasing the Shares for my own personal account for investment and not with a view to the sale or
distribution of all or any part of the Shares. 
 I understand that because the Shares have not been registered under the Securities Act, I
must continue to bear the economic risk of the investment for an indefinite time and the Shares cannot be sold unless the Shares are subsequently registered under applicable United States federal and state securities laws or an exemption from such
registration requirements is available. 
 I agree that I will in no event sell or distribute or otherwise dispose of all or any part of the
Shares unless (1) there is an effective registration statement under the Securities Act and applicable United States state securities laws covering any such transaction involving the Shares or (2) the Company receives an opinion of my
legal counsel (concurred in by legal counsel for the Company) stating that such transaction is exempt from registration or the Company otherwise satisfies itself that such transaction is exempt from registration. 

  
 Exhibit A-1 
  
  













 I consent to the placing of a legend on my certificate for the Shares stating that the
Shares have not been registered and setting forth the restrictions on transfer contemplated hereby and to the placing of a stop transfer order on the books of the Company and with any transfer agents against the Shares until the Shares may be
legally resold or distributed without restriction. 
 I understand that at the present time Rule 144 of the United States Securities and
Exchange Commission (the “SEC”) may not be relied on for the resale or distribution of the Shares by me. I understand that the Company has no obligation to me to register the sale of the Shares with the SEC and has not represented to me
that it will register the sale of the Shares. 
 I understand the terms and restrictions on the right to dispose of the Shares set forth in
the 2020 Employee, Director and Consultant Equity Incentive Plan and the Stock Option Agreement, both of which I have carefully reviewed. I consent to the placing of a legend on my certificate for the Shares referring to such restriction and the
placing of stop transfer orders until the Shares may be transferred in accordance with the terms of such restrictions. 
 I understand
and agree that if a Stockholders Agreement between the Company and certain of its stockholders is in place in relation to such stockholders’ participation in the Company (the “Stockholders Agreement”), and if I am not already a party
to the Stockholders Agreement and if the Company so requests I agree to become a party to such Stockholders Agreement by execution of the Adoption Agreement to such Stockholders Agreement attached hereto. I acknowledge that I have read and
understand the Stockholders Agreement which sets forth certain restrictions and limitations on the Shares, including the ability to transfer or sell them in the future. I further acknowledge and agree that to the extent the terms of Section 12
of the Option Agreement conflict with the Stockholders Agreement, the terms contained in the Stockholders Agreement shall govern. 

Further, I understand and agree that the Company is considering to convert into a Dutch limited liability company (Besloten Vernnootschap,
BV) or other corporation under Dutch law by effecting a share swap and having its stockholders exchange the shares in the Company into shares into a newly incorporated Dutch entity to become the owner of the shares in the Company (“Dutch
Flip”). I agree to convert the Shares into such other instrument issued in course of the Dutch flip on the same terms and conditions as the other stockholder participating in the Dutch Flip and duly execute any related documentation, as the
case may be. 
 I have considered, as applicable, any foreign and/or the United States federal, state and local income tax implications of
the exercise of my Option and the purchase and subsequent sale of the Shares. 
 I am paying the option exercise price for the Shares as
follows: 
  

                       
                                         
                                         
    
 Please issue the Shares (check one): 

☐ to me; or
