existing under the laws of the Province of Ontario and having its notice delivery address at 121 Richmond Street West, Penthouse Suite,
1300 Toronto, Ontario, M5H 2K1 Attention: Neil Maresky and an email address at neil@psyence.com.



(hereinafter called the “Corporation”)



Of
The Second Part



This
Agreement Witnesseth that in consideration of the Individual agreeing to act as a director and/or officer of the Corporation
or any subsidiary company, partnership, joint venture, trust or other enterprise (each of the Corporation and any such other subsidiary
company, partnership, joint venture, trust or other enterprise, the “Company”) and other good and valuable consideration
(the receipt and sufficiency of which are hereby acknowledged), it is agreed between the parties hereto as follows:



| | 1. | Services to the Corporation
| | -- | ---------------------------



The
Individual agrees to serve/continue to serve as a director or officer of the Corporation for so long as the Individual remains duly elected
or appointed or until he or she tenders his or her resignation or is no longer serving in such capacity. This Agreement shall not be deemed
an employment agreement between the Corporation (or any of its subsidiaries) and the Individual. The Individual specifically acknowledges
that his or her service to the Corporation is set out in a written employment or consulting agreement between the Individual and the Corporation,
or, with respect to service as a director or officer of the Corporation, by the Company's constating documents or applicable law.



| | 2. | Indemnity
| | -- | ---------



Subject to any limitations
under the Business Corporations Act (Ontario) (the “OBCA”), the rules of The Nasdaq Stock Market (stock exchange based
in New York City) (“NASDAQ Rules”) (as applicable), the U.S. Securities and Exchange Commission (“SEC”) (as applicable),
and as hereinafter provided, the Corporation, to the extent permitted under applicable law, hereby irrevocably agrees to fully indemnify
and save harmless the Individual from and against all costs, charges, expenses, losses, damages, fees (including any legal, professional
or advisory fees or disbursements and all taxes payable thereon), liabilities, and against all judgments, penalties, fines and amounts
paid to settle or dispose of any claim and reasonably incurred in connection with legal, civil, criminal, administrative or investigative
proceedings or other proceedings of any nature or kind, without limitation, whether formal or informal, and whether incurred alone or
jointly with others, including any amounts which the Individual may suffer, sustain, incur or be required to pay in respect of the investigation,
defence, settlement or appeal of or preparation for any claim or proceeding or any action to establish a right to indemnification under
this Agreement, and, for greater certainty, all taxes, interest, penalties and related outlays of the Individual arising from any indemnification
of the Individual pursuant to this Agreement (collectively, the “Expenses”), where the Individual is or was a party
or is threatened to be made a party to any threatened, pending or completed proceedings, whether legal, civil, criminal, administrative,
investigative or of any other nature or kind, by reason of the fact that the Individual is or was a director or an officer of the Corporation
or by reason of the Individual serving at the request of the Company, as applicable, as a trustee, officer, director, or agent of another
corporation, body corporate, partnership, joint venture, trust or other enterprise.












Indemnification under this Section
2 applies to the Individual if the Individual acted honestly and in good faith with a view to the best interests of the relevant Company
and, in the case of criminal proceedings, the Individual had no reasonable cause to believe that his or her conduct was unlawful (the
 “Conditions”). For the purposes of any determination made in regard to this indemnity, the Individual shall be deemed
to have had no reasonable cause to believe that his or her conduct was unlawful and to have acted in good faith and in the best interests
of the relevant Company. The Corporation shall have the burden of establishing that the Conditions have not been satisfied. The knowledge
and/or actions or failure to act of any other director, officer, trustee or agent of the Company or any other entity shall not be imputed
to the Individual for the purpose of determining the right to indemnification under this Agreement.



For the purposes of this Section
2, the termination of any proceedings by any judgment, order, settlement, conviction or the entering of a nolle prosequi does not,
by itself, create a presumption that the Individual did not act honestly and in good faith and with a view to the best interests of the
relevant Company or that the Individual had reasonable cause to believe that his or her conduct was unlawful.



| | 3. | Entitlement to Indemnification
| | -- | ------------------------------



Provided that the Conditions
have been fulfilled, subject to the OBCA, the NASDAQ Rules (as applicable) and the SEC (as applicable), the Corporation shall indemnify
the Individual under Section 2 in connection with any legal (civil or criminal), administrative, investigative or other proceeding to
which the Individual is or was a party by reason of the fact that the Individual is or was a director or an officer of the Company, or
by reason of the Individual serving at the request of the Corporation and/or the Company, as applicable, as a trustee, officer, director,
or agent of another corporation, body corporate, partnership, joint venture, trust or other enterprise, including, without limitation,
if the Individual is not wholly successful in such proceeding, and regardless of whether the Individual was judged by the court or other
competent authority to have committed any fault or omitted to do anything that the Individual ought to have done. Without limitation,
the termination of any claim, issue or matter in such a proceeding by dismissal, with or without prejudice, shall be deemed to be a successful
result as to such claim, issue or matter.



| | 4. | Scope and Survival
| | -- | ------------------



This Agreement extends to all
acts, omissions, circumstances and events, whether occurring before or after the date of this Agreement. This Agreement shall survive
any resignation by the Individual as a director and/or officer or any other circumstance by reason of which the Individual shall cease
to be a director and/or officer of any Company or by reason of the Individual serving at the request of the Corporation and/or the Company,
as applicable, as a trustee, officer, director, or agent of another corporation, body corporate, partnership, joint venture, trust or
other enterprise.



The Corporation shall use commercially
reasonable efforts to obtain and maintain directors’ and officers’ liability insurance in such amounts and covering all or
part of the Expenses which may be payable hereunder as may be approved by the Corporation’s board of directors from time to time,
acting reasonably. A copy of all such insurance policies shall be provided to the Individual.



Notwithstanding any provision
in this Agreement, the Company shall not be obligated under this Agreement to make any indemnification payment in connection with any
claim involving Individual for (i) an accounting of profits made from the purchase and sale (or sale and purchase) by Individual of securities
of the Company within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as amended from time to time (the “Exchange
Act”) or similar provisions of state statutory law or common law, (ii) any reimbursement of the Company by the Individual of
any bonus or other incentive-based or equity-based compensation or of any profits realized by the Individual from the sale of securities
of the Company, as required in each case under the Exchange Act (including any such reimbursements that arise from an accounting restatement
of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment
to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley
Act) or (iii) any reimbursement of the Company by Individual of any compensation pursuant to any compensation recoupment or clawback policy
adopted by the board of directors or the compensation committee of the board of directors, including but not limited to any such policy
adopted to comply with stock exchange listing requirements implementing Section 10D of the Exchange Act.












| | 5. | Timely Notification
| | -- | -------------------



Within five business days of
the Individual or the Corporation becoming aware of any claim, demand, action or proceeding which may give rise to indemnification hereunder
(a “Claim”), such party shall give written notice thereof, in the case of the Individual to the Corporation, and in
the case of the Company to the Individual, as soon as is reasonably practicable, provided however that failure by the Individual to give
such notice to the Corporation in a timely fashion shall not disentitle the Individual to the right to indemnity hereunder except and
to the extent that the Corporation suffers actual material prejudice by reason of the delay due to the loss of substantive defences.



| | 6. | Investigation
| | -- | -------------



The Corporation shall conduct
such investigation of each matter of which it receives notice pursuant to Section 5 as is reasonably necessary in the circumstances, and
shall pay all Expenses of such investigation, to the extent applicable.



| | 7. | Assumption of Defence
| | -- | ---------------------



The Corporation shall be entitled
to participate, at its expense, in the defence of any Claim. If the Corporation so elects after receipt of notice of a Claim, or the Individual
in such notice so directs, the Corporation shall promptly assume control of the negotiation, settlement or defence of any Claim, in which
case such defence shall be conducted by counsel chosen by the Corporation. If the Corporation elects to assume such control, the Individual
shall have the right to participate in the negotiation, settlement or defence of such Claim and to retain counsel to act on the Individual’s
behalf, provided that the fees and disbursements of such counsel shall be paid by the Individual unless the Corporation consents to the
retention of such counsel or unless the parties to any such Claim include both the relevant Company and the Individual and the Individual
shall have been advised by counsel that representation of both the relevant Company and the Individual by the same counsel would be inappropriate
due to actual or potential differing interests between them, including the availability of legal defences to the Individual which are
different from or additional to those available to the relevant Company. The Individual and the Corporation shall cooperate fully with
each other and their respective counsel in the investigation and defence of any Claim and shall make available to each other all relevant
books, records, documents and files and shall otherwise assist such counsel in the proper and adequate defence of any Claim.



| | 8. | Settlement
| | -- | ----------



The Corporation may, with the
prior written consent of the Individual (which consent shall not be unreasonably withheld or delayed), enter into a settlement or other
agreement to compromise a Claim.



If the Individual refuses after
being requested by the Corporation, acting reasonably, to give consent to the terms of a proposed settlement or compromise which is otherwise
acceptable to the Corporation, the Corporation may require the Individual to negotiate or defend the Claim independently of the Corporation.
In such event, any amount recovered by the claimant in excess of the amount for which settlement or compromise could have been made by
the Corporation shall not be recoverable under this Agreement or under the constating documents of the relevant Company, it being further
agreed by the parties that in such event the Corporation shall only be responsible for all Expenses up to the time at which such settlement
could have been made.












The Corporation shall not be
liable for any settlement of any Claim effected without its prior written consent (which consent shall not be unreasonably withheld or
delayed).



The Individual shall have the
right to negotiate a settlement in respect of any Claim, provided however that in such circumstances the Individual shall, unless the
Corporation has approved such settlement, pay any compensation or other payment to be made under the settlement and the costs of negotiating
and implementing the settlement, and shall not seek indemnity from the Corporation in respect of such compensation, payment or costs.



| | 9. | Payment of Expenses
| | -- | -------------------



Subject as herein provided,
upon demand, the Corporation shall pay all Expenses, for which the Individual is entitled to be indemnified hereunder promptly as they
are incurred and in advance of the final disposition of any action or proceeding. For clarity, subject as hereafter provided, it shall
not be necessary for the Individual to pay such Expenses, and then seek reimbursement; the Individual may provide bills and statements
of account to the Corporation for direct payment by the Corporation (including reimbursement for time spent by the Individual in connection
with any action or proceeding, at reasonable per diem rates).



Payment of the Individual’s
Expenses, as provided in the foregoing paragraph shall be subject to the prior provision by or on behalf of the Individual to the Corporation
of an undertaking, to repay to the Corporation any amounts paid by the Corporation which are subsequently determined not to be payable
by the Corporation in accordance with Section 2 which are recovered by the Individual from any third party.



If a claim for
indemnification under this Agreement is not paid in full by the Corporation within thirty (30) days after a written claim therefor has
been received by it and the applicable approval of the Court has been obtained where required, whichever is later, the Individual may
any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim, and the Individual will also be entitled
to be paid all Expenses of prosecuting such claim including but not limited to fees as between solicitor and own client on a full indemnity
basis.



| | 10. | Payment of Witness Expenses
| | --- | ---------------------------



Notwithstanding any
other provision of this Agreement, to the extent that the Individual is, by reason of the fact that the Individual is or was a director
or officer of the relevant Company, a witness or participant other than as a named party in a proceeding, the Corporation shall pay to
the Individual: (i) all out-of-pocket expenses actually and reasonably incurred by the Individual or on the Individual’s behalf
in connection therewith; and (ii) if the Individual is not currently an officer or employee of, and does not currently hold a position
equivalent to that of an officer of, the relevant Company, the Corporation will compensate the Individual, at a rate equal to the then
applicable board meeting fee received by directors of the Corporation, for each day of required attendance at or preparation for the proceeding
(prorated for partial days).



| | 11. | Availability of Other Rights
| | --- | ----------------------------



This Agreement shall not operate
to abridge or exclude any other rights, in law or in equity, to which the Individual or any Company may be entitled by operation of law
or under any statute, constitutive documents of any Company, agreement, vote of the shareholders of any Company or otherwise. Further,
subject to the limitations herein provided, in particular those set out in Section 2, the indemnity provided by this Agreement shall remain
in full force and effect notwithstanding any act or omission of the Individual as a director and/or officer, including any act or omission
under or pursuant to the relevant provisions of the statute under which the relevant Company exists or was organised, incorporated, amalgamated
or continued.












For clarity, the preceding paragraph
does not permit the Corporation, or its directors, shareholders or officers to terminate or modify this Agreement by resolution or alteration
of the Corporation’s Notice of Articles and Articles.



No action or proceeding brought
or instituted under this Agreement and no recovery pursuant hereto shall be a bar or defence to any further action or proceeding which
may be brought under this Agreement.



| | 12. | Additional Protection
| | --- | ---------------------



Notwithstanding any other provision
of this Agreement, the Corporation hereby agrees to indemnify the Individual to the fullest extent permitted by law, notwithstanding that
such indemnification is not specifically authorized by other provisions of this Agreement, the OBCA, the NASDAQ Rules (as applicable),
the SEC (as applicable) and the Corporation’s Notice of Articles and Articles, or by other statute. In the event of any change after
the date of this Agreement in any applicable law, statute or rule which expands the right of a company incorporated or continued under
the OBCA to indemnify any person who is or was a director or officer of any Company (an “Agent”), such changes, shall,
without any formality, be within the purview of the Individual’s rights and the Corporation’s obligations under this Agreement.
In the event of any change in applicable law, statute or rule which narrows the right of a company incorporated or continued under the
OBCA to indemnify an Agent, such changes, to the extent not otherwise required by such law, statute or rule to be applied to this Agreement,
shall have no effect on this Agreement or the parties’ respective rights and obligations hereunder.



The liability of the Corporation
and the rights of the Individual hereunder shall not be affected, discharged, impaired, mitigated or released by reason of the Corporation’s
bankruptcy, insolvency, receivership or other similar proceeding of creditors or the winding-up or dissolution of the Corporation.



| | 13. | Taxable Benefits
| | --- | ----------------



Should any payment made to the
Individual pursuant to this Agreement be deemed to constitute a taxable benefit or otherwise be or become subject to any tax or levy,
then the Corporation shall pay such amount as may be necessary to ensure that the amount received by or on behalf of the Individual, after
the payment of, or withholding for, such tax, fully reimburses the Individual for the actual cost, charge, expense or liability incurred
by or on behalf of the Individual.



| | 14. | Subrogation
| | --- | -----------



To the extent permitted by law,
the Corporation shall be subrogated to all rights which the Individual may have under all policies of insurance or other contracts pursuant
to which the Individual may be entitled to reimbursement of, or indemnification in respect of, all or any part of the costs, charges and
expenses which are borne by the Corporation pursuant to this Agreement. Any insurance proceeds recovered by the Individual following indemnification
shall be repaid to the Corporation.



| | 15. | Dispute Resolution Procedure
| | --- | ----------------------------



Any
dispute arising out of or in connection with this Agreement, including any question regarding its existence, validity or termination,
shall be determined by arbitration. The arbitration shall take place in the City of Toronto, in the Province of Ontario. The arbitration
decision and award shall be final and binding on all parties and will not be subject to any appeal.












| | 16. | Governing Law
| | --- | -------------



This Agreement shall be construed
in accordance with and governed by the laws of the Province of Ontario.



| | 17. | Severability
| | --- | ------------



Each section, and each provision
within each section, of this Agreement is severable, the one from the other, and if for any reason any section or provision of this Agreement
is not enforceable or is otherwise invalid at law, the remainder of this Agreement shall nonetheless be given full force and effect in
accordance with its terms.



| | 18. | Further Assurances
| | --- | ------------------



The parties hereto shall execute
such further assurances as they may reasonably request in order that the other party may resist and defend a Claim and otherwise enjoy
the full benefits of this Agreement in accordance with its terms and for that purpose shall enter into such further assignments, powers
of attorney and other documents as may reasonably be required in the circumstances. For greater certainty, each party hereby agrees that
the other party may, in the conduct of the defence of any such Claim, in the name of the first party or otherwise, file such pleadings
or other documents and take such proceedings as may reasonably be required, in the opinion of the other party and subject to the first
party's consent, to effectively make out the defence.



| | 19. | Entire Agreement
| | --- | ----------------



The
provisions herein constitute the entire agreement between the parties, and supersede all previous expectations, understandings, communications,
representations and agreements, whether verbal or written, between the parties with respect of the subject matter hereof.



| | 20. | Amendment
| | --- | ---------



No
supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No
waiver of any of the provisions of this Agreement shall be binding unless in the form of a writing signed by the party against whom enforcement
of the waiver is sought, and no such waiver shall operate as a waiver of any other provisions hereof (whether or not similar), nor shall
such waiver constitute a continuing waiver. Except as specifically provided herein, no failure to exercise or any delay in exercising
any right or remedy hereunder shall constitute a waiver thereof.



| | 21. | No Assignment; Enurement and Successors
| | --- | ---------------------------------------



No party may assign their rights
or obligations hereunder without the prior written consent of the other party. This Agreement is irrevocable and enures to, and is binding
upon, the parties hereto and their respective heirs, successors and legal representatives.



| | 22. | Notices
| | --- | -------



All notices or other communications
required or permitted to be given under this Agreement shall be sufficiently given for all purposes hereunder if in writing and personally
delivered, delivered by recognized courier service or by certified mail, return receipt requested, or sent by email communication to the
appropriate address or email address of the party as set forth on the first page of this Agreement. Notices and other communications shall
be effective upon receipt by the person to be notified.












| | 23. | Time of the Essence
| | --- | -------------------



Time shall be of the essence
for all matters in respect of this Agreement.



| | 24. | Independent Legal Advice
| | --- | ------------------------



This Agreement was prepared
by the solicitors for the Corporation. The Individual has been asked to obtain independent legal advice before signing this Agreement
and the Individual represents, by signing this Agreement that the Individual has obtained such advice or has declined to seek independent
legal advice on this Agreement, despite having been given the opportunity to do so.



| | 25. | Counterparts
| | --- | ------------



This Agreement may be executed
in any number of counterparts, each of which when executed and delivered (by electronic copy or otherwise) will be deemed to be an original,
and all of which together will constitute one and the same document.
