 5. REGULATORY MATTERS 

5.1 Responsibility for Regulatory Matters. Subject to the terms and conditions of this Agreement, including oversight by the JCC,
Otsuka shall be responsible, [***], for the conduct of all regulatory activities relating to Products in the Otsuka Territory (and in the Perception Territory solely with respect to any Ex-Otsuka Territory
Study), including (a) overseeing, monitoring and coordinating all regulatory actions, communications and filings with, and submissions to, the applicable Regulatory Authorities in the Otsuka Territory with respect to Products;
(b) interfacing, corresponding and meeting with the applicable Regulatory Authorities in the Otsuka Territory with respect to Products; (c) seeking and maintaining all Regulatory Approvals with respect to Products in the Otsuka Territory,
including any amendments, supplements or modifications to such Regulatory Approvals; and (d) maintaining and submitting all records required to be maintained or required to be submitted to the applicable Regulatory Authority with respect to
Products in the Otsuka Territory. Otsuka shall be the holder of all Regulatory Approvals for the Products in the Otsuka Territory and will own all Regulatory Documentation in the Otsuka Territory. Notwithstanding the foregoing, if Perception
(x) conducts any (i) Clinical Studies for any Product in the Otsuka Territory or (ii) Perception New Indication Studies or (y) Manufactures or has Manufactured any (i) Product in the Otsuka Territory to support Development
and Commercialization of such Product in the Perception Territory or to fulfill any of its obligations under this Agreement or (ii) Perception New Indication Product in the Otsuka Territory, then in each case ((x) and (y)) Perception shall have
the right to conduct all regulatory activities in the Otsuka Territory with respect to such activities. 
 5.2 Registration
Dossier. Otsuka shall allow Perception a reasonable opportunity to review and comment on the major sections of the Registration Dossier related to any Product ([***]) to be submitted to Regulatory Authorities in the Otsuka Territory, and for
that purpose Otsuka shall provide English versions of such Modules to Perception in advance of submission of such sections of the Registration Dossier. Within [***] after Perception’s receipt of the draft of such Modules of the
Registration Dossier, Perception will review and comment thereon. Otsuka will consider in good faith, and will incorporate, any reasonable comments timely provided by Perception in connection therewith or any reasonable revisions suggested by
Perception in good faith, unless such incorporation will materially affect the timing of filing the Registration Dossier or Otsuka has other reasonable reasons for not incorporating such comments or revisions; provided that, Otsuka shall not be
required to comply with the foregoing or delay submission of the Registration Dossier if to do so would cause Otsuka to fail to meet any deadline requested by any Regulatory Authority in the Otsuka Territory and such failure is not caused by any
action or inaction on the part of Otsuka. Otsuka shall provide Perception with a copy of the common technical document (CTD) of the Registration Dossier in Japanese at such time as it is finalized for submission to the Regulatory Authorities in the
Otsuka Territory. Each Registration Dossier submitted by Otsuka for a Product in the Otsuka Territory must be consistent with the language of the Primary Label approved by the JCC for submission to Regulatory Authorities. 

5.3 Communications with Regulatory Authorities. Subject to the last sentence of Section 5.1, Otsuka shall be solely
responsible for communications with Regulatory Authorities in the Otsuka Territory regarding the Products (and in the Perception Territory solely with respect to any Ex-Otsuka Territory Study) and in no event
will Perception unilaterally or independently communicate with any Regulatory Authority regarding the Products in the Otsuka Territory, 

  
 32 













 
except as required by Applicable Laws. In the event Perception conducts a Clinical Study for any Product in the Otsuka Territory to support Development or Commercialization of such Product in the
Perception Territory as set forth in Section 5.1, the terms of this Section 5.3 shall apply to Perception’s Material Communications with a Regulatory Authority in the Otsuka Territory relating
to such Clinical Study and shall also apply to Otsuka’s Material Communications with a Regulatory Authority in the Otsuka Territory. Each Party (the “Communicating Party”) shall provide the other Party (the “Other
Party”) with a brief written description, in English, of the principal issues raised in any Material Communication with a Regulatory Authority in the Otsuka Territory (and in the case of Otsuka, in the Perception Territory solely with
respect to any Ex-Otsuka Territory Study) (a) as soon as practicable but no later than [***] after receipt with respect to any Material Communication involving a Safety Concern or (b) within
[***] after receipt with respect to any other Material Communication. Upon Perception’s request after receiving such description from Otsuka, Otsuka shall translate such Material Communication, [***] as soon as practically
possible and shall provide to Perception such translated Material Communication promptly after completion of such translation into English. Notwithstanding the foregoing, Otsuka shall not be required to provide a brief written description or a
translation of any Material Communication that is conveyed at any meeting, teleconference or videoconference that is attended by any Perception representative. The Communicating Party will allow the Other Party a reasonable opportunity to review and
comment on the Communicating Party’s formal written correspondence with PMDA relating to a Product, including the Communicating Party’s proposed responses to Material Communications with Regulatory Authorities in the Territory with respect
to such Product, and the Communicating Party will reasonably consider any reasonable comments timely provided by the Other Party in connection therewith; provided that, the Communicating Party shall not be required to comply with the foregoing if to
do so would cause the Communicating Party to fail to meet any deadline requested or required by any Regulatory Authority in the Otsuka Territory and such failure is not caused by any action or inaction on the part of the Communicating Party. For
clarity, the terms of this Section 5.3 shall not apply to any Perception New Indication Product. 
 5.4

Perception Territory, solely with respect to any Ex-Otsuka Territory Study) relating to any Product, or with as much advance notice as practicable under the circumstances. To the extent not restricted or
prohibited by Applicable Laws or the Regulatory Authority, Perception shall have the right, [***], to have up to [***] representatives of Perception attend, as observers, such formal meetings and formal teleconferences or
videoconferences with such Regulatory Authority in the Otsuka Territory relating to any Product; provided that Otsuka shall not be obligated to change or re-schedule any such meeting in order to accommodate
the schedule of Perception’s representatives and, if attendance by Perception representatives is not restricted or prohibited by Applicable Laws or the Regulatory Authority but would require Otsuka to reduce the number of required Otsuka
participants at such meeting due to limitations on the number of attendees imposed by such Regulatory Authority, then only [***] shall be permitted to observe such meeting. Notwithstanding the foregoing, if Otsuka requests Perception to
participate in any meetings with Regulatory Authorities in the Otsuka Territory (and in the Perception Territory solely with respect to any Ex-Otsuka Territory Study) for assistance to Otsuka, then
[***]. If Perception requires an interpreter for its representatives attending any Regulatory Authority meeting in the Otsuka Territory (and in the Perception Territory solely with respect to any
Ex-Otsuka Territory Study), Perception shall retain, [***], an interpreter who can provide simultaneous interpretation unless Perception’s participation in such meeting has been specifically
requested by Otsuka, in which case [***]. 
  

  
 33 













 5.5 Assistance; Documentation. Perception will provide all assistance
reasonably requested by Otsuka in connection with the preparation and filing of the Registration Dossier and other Regulatory Documentation in the Otsuka Territory and with communications with Regulatory Authorities relating to any Product in the

reports of Clinical Studies and Non-Clinical Studies of the Products conducted by or on behalf of such Party, its Affiliates or (sub)licensees in its respective Territory (and in the case of Otsuka, in the
Perception Territory solely with respect to any Ex-Otsuka Territory Study) as such reports become available, subject to, in the case of Perception, any applicable agreement between Perception and an Other
Perception Licensee (provided, that Perception shall use Commercially Reasonable Efforts to include the right to disclose such information to Otsuka in any agreement with an Other Perception Licensee). 

5.6 Manufacturing-Related Regulatory Matters. Notwithstanding anything to the contrary in this Agreement, if Perception or its
CMO uses a drug master file process, then, until the Manufacturing Transfer Date, Perception or its CMO shall be responsible, [***], for (a) preparing the drug master file(s) containing data and information related to the Manufacture of

“Clinical Samples”) for use in the Development of Products in the Otsuka Territory under this Agreement (including for use in Non-Clinical Studies under this Agreement) and (b) will
Manufacture and supply such API and Clinical Samples to Otsuka in compliance with all Applicable Laws, including, as applicable, GLP and GMP. Otsuka will have the right to elect whether Perception (through its CMO(s)) Manufactures and supplies API
or Clinical Samples and whether any such Clinical Samples will be supplied in the form of bulk vials of Product in the Current Formulation (without labeling) or finished Product in the Current Formulation. Perception (through its CMO(s)) shall use
Commercially Reasonable Efforts to Manufacture and supply such API and Clinical Samples for the Otsuka Territory as set forth in this Article 7 until Otsuka provides written notice to Perception that it has contracted with its own CMO(s)
(which may be through assignment of Perception’s CMO agreements solely with respect to the Otsuka Territory) or otherwise has established capabilities for the Manufacture of API and Product for the Otsuka Territory and no longer requires such
Manufacture and supply by Perception (the date of such notice, the “Manufacturing Transfer Date”); provided that the Manufacturing Transfer Date shall be no later than [***]. If Otsuka elects to receive API, Otsuka (through
its CMO(s)) shall be responsible, [***], for Manufacturing Clinical Samples and if Otsuka elects to receive bulk vials of Product, Otsuka (through its CMO(s)) shall be responsible, [***], for secondary packaging of Product, in each case, for use in
Development in the Otsuka Territory. 
 7.2 Supply; Pricing. As soon as practicable, but in any event prior to [***],
the Parties will agree upon and enter into one or more clinical supply agreement(s) on reasonable and customary terms for the supply of API or Clinical Samples by Perception to Otsuka for use in Development in the Otsuka Territory (“Supply
Agreement”). Each Supply Agreement will contain reasonable and customary terms for clinical supply and will also include the terms and conditions in this Article 7, shipment and delivery terms on a FCA Origin (Incoterms 2020) basis,
and reasonable payment terms following shipment of API or Clinical Samples, as applicable, and Otsuka’s receipt of invoices and required documentation therefor. In addition to, or as part of, each Supply Agreement, the Parties will agree upon
and enter into a quality technical agreement (“Quality Agreement”) containing reasonable and customary terms and conditions regarding quality assurance, quality control and compliance with GLP, GCP and GMP (as applicable).
Perception shall supply API and Clinical Samples, as applicable, to Otsuka at a price equal to [***] [***] [***]. Perception shall have sole discretion with respect to any amendments to any 

  
 39 













 
agreements with CMO(s) existing as of the Effective Date; provided that Perception shall not amend any such agreement in a manner that would have a significant negative impact on Otsuka without
the prior consent of Otsuka, not to be unreasonably withheld, conditioned or delayed. For clarity, any such amendment that would result in a significant increase in the supply price for API or Clinical Samples shall be considered to have a
significant negative impact on Otsuka. 
 7.3 Manufacture by Otsuka. Otsuka and its Sublicensees shall have the right to
Manufacture API and Product itself or through any CMO or other Third Party manufacturer. Upon Otsuka’s written request at any time after the Effective Date but no later than [***], the Parties will discuss a schedule for
(a) assignments to Otsuka of Perception’s agreements with its CMO(s) to the extent assignable with respect to the Manufacture or supply of Clinical Samples in the Current Formulation for the Otsuka Territory (provided, that Perception
shall use Commercially Reasonable Efforts to include in any agreement with its CMO(s) the ability to assign such agreement to Otsuka), and (b) the transition of the Manufacture of API and Product in the Current Formulation for the Otsuka
Territory to Otsuka or its Sublicensees or their respective CMOs or other Third Party manufacturers; provided, that with respect to the transition of the Manufacture of API, Perception’s obligation with respect to such transition shall be
limited to providing Otsuka an introduction to Perception’s CMO(s) for API and facilitating negotiations with such CMO. The Parties will use good faith efforts to implement any such assignments requested by Otsuka in accordance with such
schedule in order for Otsuka to procure Clinical Samples in the Current Formulation directly from such CMO(s). For any such CMO agreement that is not assignable (without the consent of the CMO or otherwise), Perception will make a good faith effort
to obtain consent from the applicable CMO or to otherwise enable the assignment of such agreement to Otsuka; provided that Perception shall not be required to make any payments to such CMO to facilitate any such assignment. Additionally, at the
request of Otsuka, Perception shall provide reasonable assistance and cooperation in connection with the transition of the Manufacture of API and Product in the Current Formulation to Otsuka or its Sublicensees or their respective CMOs or other
Third Party manufacturers in accordance with such schedule agreed upon by the Parties, which assistance shall, at Otsuka’s reasonable request, include: (i) providing an introduction to Perception’s CMO(s) or other Third Party
manufacturers for API and Product and facilitating negotiations with such entities; (ii) granting any authorizations reasonably requested by Otsuka and its Sublicensees or their respective CMOs or other Third Party manufacturers in connection
with the Manufacture of Product in the Current Formulation for the Otsuka Territory; and (iii) transferring to Otsuka and its Sublicensees or their respective CMOs or other Third Party manufacturers copies of any documentation or information in
its possession or Control, including Perception Know-How, related to the Manufacture of Product in the Current Formulation and [***]; provided, that in no event shall Perception be required to provide
any information, assistance or cooperation with respect to the Manufacture of API other than as set forth in the foregoing clause (i). 

7.4 Validation and Testing. Prior to the Manufacturing Transfer Date, at Otsuka’s reasonable request and, if applicable, as
required by any Regulatory Authority in the Otsuka Territory, Perception shall conduct validation, analytical, stability and any other specific testing of API and Clinical Samples Manufactured and supplied by or on behalf of Perception for the
Otsuka Territory, and [***]. In addition, at Otsuka’s reasonable request prior to the Manufacturing Transfer Date, Perception will provide assistance and one or more technology transfer(s) to Otsuka or its designee of information
(including test methods for Clinical Sample QA/QC) necessary or reasonably useful to support Otsuka’s acceptance activities and, if applicable, secondary packaging of Clinical Samples, and for Otsuka to fulfill quality management
responsibilities relating to Clinical Samples and [***]. 

  
 40 













 7.5 Audits and Inspections. 

7.5.1 By Otsuka. If Perception elects to inspect or audit any facilities of its CMOs or other Third Party manufacturers or Third Party
laboratories with respect to Manufacture or testing of API or Clinical Samples for the Otsuka Territory, Perception shall notify Otsuka of such inspection or audit and to the extent permitted under the agreement with the applicable CMO or other
Third Party manufacturer or laboratory and subject to any conditions set forth in such agreement with respect to any inspection or audit (e.g., entering into a confidentiality agreement with the applicable CMO or other Third Party), Otsuka shall
have the right, but not the obligation, to have [***] (together with an interpreter) participate in such inspection or audit or to accompany Perception and observe and review such inspection or audit. Perception shall use Commercially
Reasonable Efforts to include in each future agreement between Perception and such CMOs and other Third Party manufacturers and Third Party laboratories (and, to the extent not already included, to amend any such existing agreement to include) such
inspection and audit rights for Otsuka as provided in this Section 7.5.1 and as provided in the Supply Agreement and Quality Agreement. In addition, Perception shall provide Otsuka with copies of all reports of Perception’s audits
or inspections of its CMOs and other Third Party manufacturers and Third Party laboratories relating to Manufacture or testing of API and Clinical Samples for the Otsuka Territory. Perception retains the right to conduct “for cause” audits
of the facilities of its CMOs, other Third Party manufacturers and Third Party laboratories; provided that, if Otsuka identifies the need to perform a “for cause” audit of such facilities to address quality or compliance issues related to
API or Clinical Samples Manufactured for the Otsuka Territory (including to address any notice from a Governmental Authority of noncompliance with Applicable Laws), as well as in connection with the preparation for submission of Regulatory
Documentation in Otsuka Territory and in response to Regulatory Authority requirements in the Otsuka Territory, Otsuka shall notify Perception and Perception shall schedule and conduct such audit to the extent permitted pursuant the applicable
agreement with the such CMO, Third Party manufacturer or Third Party laboratory. 
 7.5.2 By Governmental Authority. If any
Governmental Authority carries out or gives notice of its intention to carry out any inspection or audit of Perception’s CMOs or other Third Party manufacturers or Third Party laboratories in relation to Manufacture or testing of API or
Clinical Samples for the Otsuka Territory, Perception shall promptly notify Otsuka thereof and Perception shall, to the extent permitted by its agreement with the applicable CMO, Third Party manufacturer or Third Party laboratory, permit Otsuka to
observe any such inspection or audit to the extent related to the Manufacture or testing of API or Clinical Samples for the Otsuka Territory. Following receipt of the inspection results or audit observations of the Governmental Authority from such
inspection or audit (a redacted copy of which Perception will promptly provide to Otsuka to the extent it relates to the API or Clinical Samples Manufactured or tested for the Otsuka Territory), Perception will prepare any appropriate responses.
Perception shall provide a copy of such responses to Otsuka for review and comment in advance of the date such responses are due, to the extent such responses pertain to the Manufacture or testing of API or Clinical Samples for the Otsuka Territory,
and Perception shall consider Otsuka’s comments in good faith prior to responding. 

  
 41 













 7.6 Third Party Contractors. Each Party shall be entitled to utilize the
services of CMOs or other Third Parties to perform Manufacturing activities under this Agreement, provided that (a) each agreement between a Party and such CMO or other Third Party shall be consistent with applicable terms and conditions in
this Agreement and shall include a requirement that the Third Party Contractor comply with all applicable terms and conditions of this Agreement, including the confidentiality and non-use provisions of
Article 10 with respect to such Party’s Confidential Information and (b) the contracting Party shall remain primarily liable to the other Party for the performance of all of the contracting Party’s obligations hereunder.

	Greater than [***]	  	 	[***]	 

 8.4.2 Royalty Term. The period during which the royalties set forth in Section 8.4.1 shall
be payable, on a Product-by-Product basis, shall commence on the date of First Commercial Sale of such Product and continue until the latest of (a) the date of
expiration of the last Valid Claim of a Perception Patent Right (including any patent term extension available and granted for such claim) that Covers such Product in the formulation and for the indication for which such Product has obtained
Regulatory Approval in the Field in the Otsuka Territory, (b) the expiration of Regulatory Exclusivity for such Product in the Field in the Otsuka Territory and (c) the tenth (10th) anniversary of the First Commercial Sale of the first
Product sold in the Field in the Otsuka Territory (“Royalty Term”). For clarity, upon expiration of the Royalty Term for a Product, no further royalties shall be payable with respect to such Product, and from and after the
expiration of the Royalty Term for a Product, Net Sales of such Product shall be excluded for purposes of calculating the Net Sales thresholds set forth in Section 8.4.1. 

8.4.3 Royalty Reductions. 

(a) [***] 
 (b) [***] 

(c) Otsuka Third Party Payments. With respect to each Product, Otsuka may deduct [***] of the sum of (i) all Otsuka Third Party
Payments for such Product and (ii) all Global Third Party IP Payments for such Product against the royalties payable by Otsuka to Perception under Section 8.4.1 on the Net Sales of such Product in the Otsuka Territory;
provided that the royalties that otherwise would be payable to Perception on the Net Sales for such Product shall not be reduced by more than [***] in any given Calendar Quarter as a result of any deduction under this
Section 8.4.3(c); and provided further, that Otsuka shall be entitled to carry forward to subsequent Calendar Quarters any amounts with respect to which Otsuka would have been entitled to take a deduction pursuant to this
Section 8.4.3(c) but is unable to take such deduction pursuant to the first proviso in this Section 8.4.3(c). “Otsuka Third Party Payments” mean all payments by Otsuka to a Third
Party (including all upfront payments, milestone payments, license fees, royalties and other amounts payable to such Third Party for such rights, in each case to the extent reasonably allocable to a Product in the Otsuka Territory) to acquire,
through a license, acquisition or other agreement with such Third Party, rights under such Third Party’s Patent Rights that are necessary or reasonably useful for the Development, Manufacture or Commercialization of a Product in the Otsuka
Territory under this Agreement other than any Patent Rights that are specific to an Other Product. 

  
 44 













 (d) Cumulative Reductions Floor. In no event will the royalty rates under
Section 8.4.1 in any given Calendar Quarter during the Royalty Term for a Product be reduced by more than [***] of the royalty rates that otherwise would have applied in such Calendar Quarter for such Product but for the
reductions set forth in this Section 8.4.3. 
 8.4.4 Patent Challenge. If Otsuka or any of its Sublicensees
initiates (or in any way, directly or indirectly, aids any Third Party in initiating) a declaratory judgment action or similar action or claim that any Perception Patent Right is invalid, unenforceable or not infringed by the manufacture,
importation, sale, offer for sale or other disposal of a Product in the Otsuka Territory (a “Patent Challenge”), and (a) a court of competent jurisdiction upholds the validity, enforceability or infringement of such Perception
Patent Right, (b) such Patent Challenge is dismissed with or without prejudice, or (c) Otsuka or its Sublicensee voluntarily withdraws such Patent Challenge, then Otsuka shall pay Perception [***] after such Perception Patent Right is held
to be valid, enforceable or infringed or such action or claim is dismissed or withdrawn. As used herein, “Challenged Perception Patent Right Products” means any Product for which the Development, Manufacture or Commercialization in
the Field in the Otsuka Territory would infringe a Valid Claim in a Perception Patent Right that is the subject of a Patent Challenge. Notwithstanding the foregoing, the provisions of this Section 8.4.4 shall not apply to any Patent
Challenge if (i) within [***] after receipt of written notice from Perception, Otsuka or its Sublicensee voluntarily withdraws such Patent Challenge (or in the case of ex-parte proceedings, multi-party
proceedings, or other actions or claims that Otsuka or such Sublicensee does not have the power to unilaterally withdraw or cause to be withdrawn, Otsuka and its Sublicensee, as applicable, knowingly ceases providing any direction to any Person with
respect to such Patent Challenge and, to the extent Otsuka or any of its Sublicensee is a party to such Patent Challenge, it withdraws from such Patent Challenge), (ii) such Patent Challenge is initiated by Otsuka’s Sublicensee and within [***]
after receipt of written notice from Perception, Otsuka terminates such Sublicensee’s sublicense under the license granted to Otsuka under this Agreement, or (iii) such Patent Challenge is made by Otsuka in response to and defense of any
claim or action that Perception first asserts against Otsuka or any of its Affiliates or Sublicensees. 
 8.5 Royalty Report and
Payment. Within [***] after the end of each Calendar Quarter during the Royalty Term, Otsuka will provide to Perception a written report (each, a “Royalty Report”) setting forth, on a Product-by-Product basis (a) the quantity and description of such Product sold in the Otsuka Territory during such Calendar Quarter, (b) the calculation of the aggregate Net Sales of such Product in
the Otsuka Territory (including the amount of gross sales) for such Calendar Quarter, (c) the applicable royalty rates and exchange rates used to calculate the royalties payable for such Product for such Calendar Quarter, (d) any
adjustments to royalties in accordance with Section 8.4.3 for such Product for such Calendar Quarter, and (e) the royalties due under Section 8.4 for such Product for such Calendar Quarter. Upon or after receipt of the
Royalty Report, Perception shall send Otsuka an invoice (and, if there has been any change to a Payment Form previously submitted, or if a previously submitted Payment Form has expired, updated Payment Forms) for the royalties payable and, within
[***] of receipt of such invoice (and Payment Form, if applicable), Otsuka shall pay the associated royalties. The information contained in each Royalty Report shall be the Confidential Information of Otsuka. 

  
 45 













 8.6 Records; Financial Audit. Each Party shall maintain complete and accurate
books and records in sufficient detail in relation to this Agreement to permit the other Party to confirm the accuracy of the amount of royalties, [***] and other payments (including supply price for Clinical Samples) due under this Agreement and
the Supply Agreement. Each Party will keep such books and records for at least [***] years following the Calendar Year to which they pertain. Upon at least [***] prior notice, each Party (the “Auditing Party”) shall have the right
to inspect and audit such books and records of the other Party (the “Audited Party”) during regular business hours at such place or places where such records are customarily kept, by an independent certified public accounting firm
of internationally-recognized standing (the “Auditor”) selected by the Auditing Party and reasonably acceptable to the Audited Party for the sole purpose of verifying for the Auditing Party the accuracy of the financial reports,
statements or invoices furnished by the Audited Party pursuant to this Agreement or the Supply Agreement or of any payments made or charged by the Audited Party pursuant to this Agreement or the Supply Agreement. Before beginning its audit, the
Auditor shall execute a written agreement reasonably acceptable to Audited Party by which the Auditor agrees to keep confidential all information reviewed during the audit. Such audits may occur no more often than once each Calendar Year and not
more frequently than once with respect to records covering any specific period of time. Each Auditing Party shall only be entitled to audit the Audited Party’s books and records from the [***] Calendar Years prior to the Calendar Year in which
the audit request is made. The Auditor shall not disclose the Audited Party’s Confidential Information to the Auditing Party, except to the extent such disclosure is necessary to verify the accuracy of the financial reports, statements or
invoices furnished by the Audited Party or the amount of payments to or by the Audited Party under this Agreement. If the final result of the audit reveals that (a) additional amounts were owed by one Party to the other Party, the owing Party
shall pay the additional amounts (and, if such additional amounts are owed due to an error in an invoice or report provided by such owing Party, with interest thereon as provided in Section 8.10) or (b) excess payments were made by
one Party to the other Party, the overpaid Party shall reimburse such excess payments (and, if such excess payments were made due to an error in an invoice or report provided by such overpaid Party, with interest thereon as provided in
Section 8.10), in either case ((a) or (b)) within [***] after the Auditor’s report. The Auditing Party shall bear the full cost of such audit unless such audit reveals an overpayment to, or an underpayment by, the Audited Party that
resulted from a discrepancy in the financial report, statement or invoice provided by the Audited Party for the audited period, which underpayment or overpayment was more than [***] of the amount set forth in such report, in which case the Audited
Party shall reimburse the Auditing Party for the costs for such audit. Unless an audit for a Calendar Year has been commenced prior to the [***] anniversary of the end of such Calendar Year, the financial reports, statements or invoices furnished by
the Audited Party and the payments made or charged by the Audited Party pursuant to this Agreement or the Supply Agreement with respect to such Calendar Year shall be binding and conclusive upon both Parties, and the Audited Party shall be released
from any further liability or accountability with respect thereto, except (x) if the Auditing Party has a reasonable basis to believe that the Audited Party has committed fraud or (y) if the Audited Party (or any Affiliate that controls
the Audited Party) restates its financial statements for such Calendar Year. The Auditing Party shall treat all financial information subject to review under this Section 8.6 in accordance with the confidentiality and non-use provisions of Article 10. 

  
 46 













 8.7 Reimbursement. For all amounts for which a Party (the “Owing
Party”) is obligated to reimburse or pay the other Party (the “Owed Party”) pursuant to this Agreement for which no specific provision is made hereunder for such payment, the Owed Party shall send to the Owing Party an
invoice for such amount promptly after the Owed Party’s determination that such amount is payable by the Owing Party, which invoice shall include a reference to the section of this Agreement under which the Owed Party is requesting
reimbursement or payment and be accompanied by reasonable documentation of the incurrence of the costs to be reimbursed, which shall include copies of Third Party invoices reflecting the Out-of-Pocket Costs actually incurred by the Owed Party with respect to such amount; [***] Payment with respect to each such invoice shall be due within [***] after receipt by the Owing Party thereof
and shall be made in accordance with Section 8.9; provided that if the Owing Party in good faith disputes any portion of any such invoice, it shall pay the undisputed portion and shall provide the Owed Party with written notice of the disputed
portion and its reasons therefor, and the Owing Party shall not be obligated to pay such disputed portion unless and until such dispute is resolved in favor of the Owed Party. The Parties shall use good faith efforts to resolve any such disputes
promptly in accordance with Section 8.8. 
 8.8 Financial Dispute. In the event of a dispute with respect to any payments
pursuant to Section 8.7 or the audit under Section 8.6, Perception and Otsuka shall work in good faith to resolve the dispute. If the Parties are unable to reach a mutually acceptable resolution of any such dispute within
[***] from the date either Party informs the other of a dispute under this Section 8.8, the dispute shall be submitted for resolution to a certified public accounting firm jointly selected by each Party’s certified public
accountants or to such other Person as the Parties shall mutually agree (the “Dispute Auditor”) for expert determination. The decision of the Auditor, who shall act as an expert and not as an arbitrator, shall be final and the costs
of such expert determination, and if applicable, the initial audit shall be borne between the Parties in such manner as the Dispute Auditor shall determine. If the Dispute Auditor’s decision concludes that (x) additional amounts were owed
by one Party to the other Party, the owing Party shall pay the additional amounts (and, if such additional amounts are owed due to an error in an invoice or report provided by such owing Party, with interest thereon as provided in
Section 8.10) or (y) excess payments were made by one Party to the other Party, the overpaid Party shall reimburse such excess payments (and, if such excess payments were made due to an error in an invoice or report provided by such
overpaid Party, with interest thereon as provided in Section 8.10), in either case ((x) or (y)), within [***] after such decision and in accordance with such decision. 

8.9 Exchange Rate; Manner and Place of Payment. All payments hereunder shall be payable in U.S. Dollars and all references to
Dollars and “$” herein shall refer to U.S. Dollars. When conversion of Net Sales from any currency other than U.S. Dollars is required, such conversion shall be calculated using Otsuka’s standard conversion method consistent
with IFRS or GAAP in a manner consistent with Otsuka’s customary and usual conversion procedures used in preparing its financial statements applied on a consistent basis, provided that such procedures use a widely accepted source of published
exchange such as published by OANDA.com. Upon Perception’s request, Otsuka shall provide Perception a description of such conversion procedures. All payments owed under this Agreement shall be made by wire transfer in immediately available
funds to a bank and account designated in writing by the payee Party, unless otherwise specified in writing by such payee Party. 

  
 47 













 8.10 Late Payments. If any payment due under this Agreement is not paid when
due in accordance with the applicable provisions of this Agreement, simple interest shall thereafter accrue on the sum due from the due date until the date of payment at a per-annum rate of [***] or the
maximum rate allowed by Applicable Law, whichever is less. 
 8.11 Taxes. 

8.11.1 General. Except as otherwise provided in this Section 8.11, each Party shall be solely responsible for its own tax
liability imposed on account of, or measured in whole or in part by reference to, payments made under this Agreement. Any information provided by one Party to the other Party in connection with tax pursuant to this Section 8.11 shall be
treated as Confidential Information under this Agreement; provided that each Party shall be entitled to disclose such information to the extent required by any Applicable Law or as conducive to the conduct of any tax contest or administrative or
judicial proceeding in relation to the taxes described in Section 8.11.2, Section 8.11.3, or Section 8.11.4, as applicable, with any taxing authority, as determined in the reasonable discretion of such Party or
its tax advisors. 
 8.11.2 Withholding Tax. Each Party shall cooperate with the other Party and use reasonable efforts to avoid or
reduce any deduction or withholding on account of tax (or similar obligations) in respect of any payment made by one Party (the “Payor”) to the other Party (the “Recipient”) under this Agreement. To the extent the
Payor is required by Applicable Laws to deduct and withhold taxes on any payment to the Recipient hereunder, the Payor shall (a) be authorized to deduct and withhold such taxes, (b) remit the amount of such withheld taxes to the proper
Governmental Authority in a timely manner in accordance with Applicable Law, and (c) promptly transmit to the Recipient an official tax certificate or other evidence of such remittance. The Payor shall notify the Recipient prior to any such
withholding of taxes and describe in reasonable detail the basis therefor. The Payor shall reasonably cooperate with the Recipient in obtaining a reduction of the rate of, or exemption from, any such withholding as may legally be available
(including under any income tax treaty) in respect of such payment to the Recipient. The Recipient shall provide the Payor any tax forms that may be reasonably necessary in order for the Payor to obtain a reduction of the rate of, or exemption from,
withholding under Applicable Law (including under any income tax treaty). The Recipient and the Payor shall use reasonable efforts to ensure that any such tax form is furnished to the Payor before the due date of the relevant payment. This
provisions of this Section 8.11.2 shall not apply to Indirect Taxes. 
 8.11.3
Gross-Up of Withholding Tax. If the Payor is required to make a payment to the Recipient hereunder, which payment is subject to withholding tax that arises from or is increased solely as the result of the
assignment or transfer of this Agreement (in whole or in part) by the Payor to an Affiliate or Third Party (a “Withholding Tax Action”), then notwithstanding anything to the contrary herein, the Payor shall be responsible for and
bear the economic burden of the resulting additional withholding taxes to the extent thereof in such a manner so that the Recipient shall receive the same amount, after deduction and withholding on account of taxes with respect to such payment as it
would have received absent such Withholding Tax Action. 

  
 48 













 8.11.4 Indirect Tax. Notwithstanding anything to the contrary in this
Section 8.11, all payments under this Agreement are exclusive of Indirect Taxes. If any amount of Indirect Tax is chargeable in respect of a payment under this Agreement, the Payor shall pay such Indirect Tax at the applicable rate in
respect of such payment following the receipt of an invoice in the appropriate form from the Recipient in respect of those payments. Such Indirect Tax shall be payable on the later of (a) the due date of the payment to which such Indirect Tax
relates and (b) [***] after the receipt by the Payor of the applicable invoice setting forth the amount of the applicable Indirect Tax. The Parties will issue invoices for all amounts due under this Agreement consistent with applicable
Indirect Tax requirements.

 9.1.1 Know-How. All Know-How, excluding Inventions, generated in connection with the Development or Commercialization of any Product conducted by or on behalf of Perception or
its Sublicensees shall, as between the Parties, be the sole and exclusive property of Perception. All Know-How, excluding Inventions, generated in connection with the Development or Commercialization of any
Product conducted by or on behalf of Otsuka or its Sublicensees shall, as between the Parties, be the sole and exclusive property of Otsuka. For clarity, each Party shall have access and right to use and reference the other Party’s Know-How (except for Inventions, which are addressed in Section 9.1.2) as and to the extent set forth in this Agreement (and, as applicable, subject to [***]). To the extent a patentable Invention
Controlled by a Party is supported by any Know-How owned by the other Party, the Party Controlling such Invention shall have the right, upon the other Party’s prior written consent (not to be unreasonably
withheld, conditioned or delayed), subject to [***], to use and disclose such Know-How owned by the other Party in its patent applications to support such Invention. 

9.1.2 Inventions. Inventorship for Inventions shall be determined in accordance with applicable patent laws for determining
inventorship. Ownership of Inventions will be allocated as provided in this Section 9.1.2 and the Parties will work together to resolve any issues regarding inventorship or ownership of Inventions. As between the Parties, Perception
shall own the entire right, title and interest in and to all Inventions discovered, made, developed generated, or conceived solely by one or more employees of Perception or its Sublicensees (or a Third Party acting on any of their behalf) during the
Term. As between the Parties, Otsuka shall own the entire right, title and interest in and to all Inventions discovered, made, developed generated, or conceived solely by one or more employees of Otsuka or its Sublicensees (or a Third Party acting
on any of their behalf) during the Term. The Parties shall jointly own, and shall have an equal, undivided interest in, the entire right, title and interest in and to all Inventions discovered, made, developed generated, or conceived jointly by one
or more employees of Perception or its Sublicensees (or a Third Party acting on any of their behalf) and one or more employees of Otsuka or its Sublicensees (or a Third Party acting on any of their behalf) during the Term (“Joint
Inventions”). All Patent Rights claiming Joint Inventions shall be referred to herein as “Joint Patent Rights”. Each Party will disclose to the other any Inventions discovered, made, developed generated, or conceived by or
on behalf of such Party or its Sublicensees no later than [***] days after such Party’s intellectual property department receives notice of the same.

 9.1.3 Right to Practice Joint Technology. Subject to the rights and licenses of the
Parties hereunder (including the licenses granted under Section 2.1 and Section 2.2), both Parties are entitled to practice Joint Technology for all purposes on a worldwide basis and to license Joint Technology without the
consent of and without a duty of accounting to the other Party. For clarity, Perception shall have no right to grant any rights or licenses under Joint Technology that would conflict with the exclusive license to Otsuka under
Section 2.1.1 and Otsuka shall have no right to grant any rights or licenses under Joint Technology that would conflict with the exclusive license to Perception under Section 2.2.1. Each Party will
grant and hereby does grant all permissions, consents and waivers with respect to, and all licenses under, the Joint Technology, throughout the world, necessary to provide the other Party with such rights of use and exploitation of the Joint
Technology, and will execute documents as necessary to accomplish the foregoing. 
 9.1.4 Employee Assignment. Each Party shall ensure
that all of its employees and all employees of its Sublicensees who are acting under its or such Sublicensees’ authority in the performance of this Agreement assign to such Party (or to such Sublicensee for further assignment to such Party)
under a binding agreement all Know-How and Patent Rights discovered, made, developed generated, or conceived by such employee as a result of such employee’s employment. In the case of any Third Parties
acting in the performance a Party’s obligations under this Agreement, including consultants, subcontractors, independent contractors, clinical investigators, and employees of non-profit institutions, the
Party that engages such Third Party shall use commercially reasonable efforts to ensure that such Third Party is also so obligated to assign, unless otherwise approved by the other Party. 

9.2 Prosecution and Maintenance of Patent Rights. 

9.2.1 Perception Patent Rights. 

(a) Perception shall have the first right, but not the obligation, to control the preparation, filing, prosecution and maintenance (including
any interferences, reissue proceedings, reexaminations, applications for supplementary protection certificates and oppositions) (collectively, “Prosecution”) of the Perception Patent Rights worldwide. Perception shall keep Otsuka
informed of material progress with regard to Prosecution of Perception Patent Rights in the Otsuka Territory and shall provide Otsuka (or have provided to Otsuka) all filings and material correspondence related thereto for the Otsuka Territory
within a reasonable time after the receipt or prior to the filing of such documents, to allow Otsuka and its patent counsel to be able to review and provide comments to Perception and its patent counsel regarding the filing and contents of such
application, amendment, submission, response or other documents, including the content and timing of Perception Patent Rights in the Otsuka Territory, provided that such review and comment shall not delay the Prosecution. Perception shall consult
with, and consider in good faith the comments, requests and suggestions of, Otsuka with respect to Prosecution of Perception Patent Rights in the Otsuka Territory. 

(b) Perception shall not, without the prior written consent of Otsuka (not to be unreasonably withheld, conditioned or delayed), abandon,
forfeit or otherwise cease the Prosecution of any Perception Patent Rights in the Otsuka Territory; provided that Otsuka acknowledges and agrees that it would be unreasonable for it to condition, withhold or delay such consent if Perception has, and
informs Otsuka of, a reasonable strategic reason for ceasing the Prosecution of such Perception Patent Rights in the Otsuka Territory. If Perception wishes to abandon, forfeit or otherwise cease Prosecution of any Perception Patent Right in the
Otsuka 

  
 50 













 
Territory, Perception shall provide reasonable prior written notice to Otsuka (which notice shall, to the extent possible, be given at least [***] before such Patent Right would become
abandoned or forfeited) and if Otsuka consents to the same, then unless Perception provides Otsuka with a reasonable explanation as to why Perception reasonably believes that continuing Prosecution would adversely affect Perception’s global
patent prosecution or litigation strategy, Otsuka may, upon written notice to Perception, elect to assume Prosecution of such Perception Patent Right (in the name of Perception) in the Otsuka Territory [***]. If Otsuka elects to assume
Prosecution of such Perception Patent Right in the Otsuka Territory, such Patent Right in the Otsuka Territory shall cease to be included within Perception Patent Rights for purposes of determining the Royalty Term under this Agreement. For clarity,
if Otsuka does not elect to assume Prosecution of such Perception Patent Right, and provided that Otsuka has given its prior written consent, Perception will have the right to cease the Prosecution of such Perception Patent Right in the Otsuka
Territory. 
 (c) [***]. 

9.2.2 Otsuka Product Improvement Patents. 

(a) Otsuka shall have the first right, but not the obligation, to control the Prosecution of Otsuka Product Improvement Patents in the Otsuka
Territory and other countries selected by Otsuka by written notice to Perception (collectively, “Otsuka Selected Countries”); provided that Otsuka may not, without the prior written consent of Perception, add to the Otsuka Selected
Countries any country in which Perception has already begun Prosecuting any Otsuka Product Improvement Patents pursuant to Section 9.2.2(d). Otsuka shall keep Perception informed of material progress with regard to
Prosecution of Otsuka Product Improvement Patents in Otsuka Selected Countries in the Perception Territory and shall provide Perception (or have provided to Perception) all filings and material correspondence related thereto, within a reasonable
time after the receipt or prior to the filing of such documents, to allow Perception and its patent counsel to be able to review and provide comments to Otsuka and its patent counsel regarding the filing and contents of such application, amendment,
submission, response or other documents, including the content, timing and jurisdiction of the filing of Otsuka Product Improvement Patents in the Otsuka Selected Countries in the Perception Territory, provided that such review and comment shall not
delay the Prosecution. Otsuka shall consult with, and consider in good faith the comments, requests and suggestions of, Perception with respect to Prosecution of Otsuka Product Improvement Patents in the Otsuka Selected Countries in the Perception
Territory. 
 (b) If Otsuka intends to abandon, forfeit or otherwise cease Prosecution of any Otsuka Product Improvement Patent in an Otsuka
Selected Country in the Perception Territory, Otsuka shall provide reasonable prior written notice to Perception of such intention (which notice shall, to the extent possible, be given at least [***] before such Patent Right would become
abandoned or forfeited) and unless Otsuka provides Perception with a reasonable explanation as to why Otsuka reasonably believes that continuing Prosecution would adversely affect Otsuka’s patent prosecution or litigation strategy in the Otsuka
Selected Countries, Perception may, upon written notice to Otsuka, elect to assume Prosecution of such Otsuka Product Improvement Patent (in the name of Otsuka) in such Otsuka Selected Country in the Perception Territory [***]. For clarity,
if Perception does not elect to assume Prosecution of such Otsuka Product Improvement Patent, Otsuka will have the right to cease the Prosecution of such Otsuka Product Improvement Patent in such Otsuka Selected Country in the Perception Territory.


  
 51 













 (c) [***]. 

(d) Perception shall have the first right, but not the obligation, [***], to control the Prosecution of Otsuka Product Improvement
Patents, in the name of Otsuka, in countries in the Perception Territory that are not Otsuka Selected Countries. Perception shall keep Otsuka informed of material progress with regard to Prosecution of Otsuka Product Improvement Patents in such
countries in the Perception Territory and shall provide Otsuka (or have provided to Otsuka) all filings and material correspondence related thereto, within a reasonable time after the receipt or prior to the filing of such documents, to allow Otsuka
and its patent counsel to be able to review and provide comments to Perception and its patent counsel regarding the filing and contents of such application, amendment, submission, response or other documents, including the content, timing and
jurisdiction of the filing of Otsuka Product Improvement Patents in such countries in the Perception Territory, provided that such review and comment shall not delay the Prosecution. Perception shall consult with, and consider in good faith the
comments, requests and suggestions of, Otsuka with respect to Prosecution of Otsuka Product Improvement Patents in such countries in the Perception Territory. 

(e) If Perception intends to abandon, forfeit or otherwise cease Prosecution of any Otsuka Product Improvement Patent in an any country in the
Perception Territory that is not an Otsuka Selected Country, Perception shall provide reasonable prior written notice to Otsuka of such intention (which notice shall, to the extent possible, be given at least [***] before such Patent Right
would become abandoned or forfeited) and, in that event, Otsuka may, upon written notice to Perception, elect to assume Prosecution of such Otsuka Product Improvement Patent in such country in the Perception Territory. If Otsuka elects to assume
Prosecution of such Otsuka Product Improvement Patent, (i) the license granted to Perception with respect to such Otsuka Product Improvement Patent under Section 2.2.1 shall become nonexclusive, and (ii) Otsuka
shall Prosecute such Otsuka Product Improvement in such country in the Perception Territory [***]. For clarity, if Otsuka does not elect to assume Prosecution of such Otsuka Product Improvement Patent in such country in the Perception
Territory, Perception will have the right to cease the Prosecution of such Otsuka Product Improvement Patent in such country in the Perception Territory. 

(f) [***]. 
 9.2.3
Joint Patent Rights. 
 (a) Perception shall have the first right, but not the obligation, to Prosecute Joint Patent Rights in
the Otsuka Territory and in all other countries in which the Parties mutually agree to Prosecute Joint Patent Rights (such other countries, “Mutually Selected Countries”) using patent counsel mutually agreed to by the Parties.
Perception shall keep Otsuka informed of material progress with regard to Prosecution of Joint Patent Rights in the Otsuka Territory and all Mutually Selected Countries and shall provide Otsuka (or have provided to Otsuka) all filings and material
correspondence related thereto within a reasonable time after the receipt or prior to the filing of such documents to allow Otsuka and its patent counsel to be able to review and provide comments to Perception and its patent counsel regarding the
timing for filing and the content of such application, amendment, submission, response or other documents relating to Joint Patent Rights in the Otsuka Territory and Mutually Selected Countries, provided that such review and comment shall not delay
the Prosecution. Perception shall consult with, and consider in good faith the comments, requests and suggestions of, Otsuka with respect to its Prosecution of Joint Patent Rights in the Otsuka Territory and Mutually Selected Countries. 

  
 52 













 (b) If Perception intends to abandon, forfeit or otherwise cease Prosecution of any Joint
Patent Right in the Otsuka Territory or any Mutually Selected Country, Perception shall provide reasonable prior written notice to Otsuka of such intention (which notice shall, to the extent possible, be given at least [***] before such
Patent Right would become abandoned or forfeited) and, in that event, Otsuka may, upon written notice to Perception, elect to assume Prosecution of such Joint Patent Right in such country. If Otsuka elects to assume Prosecution of such Joint Patent
Right in such country, (i) Perception shall assign all of its right, title and interest in and to such Joint Patent Right in such country to Otsuka [***], and (ii) Otsuka shall Prosecute such Patent Right (in the name of Otsuka
only) in such country [***]; provided that if Perception notifies Otsuka at a later date of its desire to license such Patent Right, the Parties shall negotiate in good faith a non-exclusive,
royalty-bearing license to Perception under such Patent Right on commercially reasonable terms; provided, further, that if the Parties are unable to agree on such commercially reasonable terms within [***] following Otsuka’s receipt of
Perception’s notice (or such longer period as the Parties may agree), then the matter shall be subject to resolution in accordance with Section 14.3. For clarity, if Otsuka does not elect to assume Prosecution of such
Joint Patent Right, Perception will have the right to cease the Prosecution of such Joint Patent Right in such country. 
 (c) With respect
to any Joint Patent Right that Perception is Prosecuting in any Mutually Selected Country, Otsuka may at any time give written notice to Perception that Otsuka does not wish to remain a joint owner of such Joint Patent Right in such country and, at
such time, Otsuka shall assign all of its right, title and interest in and to such Joint Patent Right in such country to Perception; provided that if Otsuka notifies Perception at a later date of its desire to license such Patent Right, the Parties
shall negotiate in good faith a non-exclusive, royalty-bearing license to Otsuka under such Patent Right on commercially reasonable terms; provided, further, that if the
Parties are unable to agree on such commercially reasonable terms within [***] following Perception’s receipt of Otsuka’s notice (or such longer period as the Parties may agree), then the matter shall be subject to resolution in
accordance with Section 14.3. Thereafter, Perception shall have the sole right, but not the obligation, to Prosecute such Patent Right in the name of Perception only in such country [***]. 

(d) [***]. 
 (e) If a
Party wishes to Prosecute a Joint Patent Right in a country other than the Otsuka Territory or any Mutually Selected Country, such Party shall notify the other Party and, unless the other Party elects to include such country in the Mutually Selected
Countries, then (i) the other Party shall assign all of its right, title and interest in and to such Joint Patent Right in such country to the Party that wishes to Prosecute such Joint Patent Right (the “Prosecuting Party”),
and (ii) the Prosecuting Party will have the sole right to Prosecute such Patent Right in the name of the Prosecuting Party only in such country [***]; provided that if the other Party notifies the Prosecuting Party at a later date of
its desire to license such Patent Right, the Parties shall negotiate in good faith a non-exclusive, royalty-bearing license to the other Party under such Patent Right on commercially reasonable terms;
provided, further, that if the Parties are unable to agree on such commercially reasonable terms within [***] following the Prosecuting Party’s receipt of the other Party’s notice (or such longer period as the Parties may agree),
then the matter shall be subject to resolution in accordance with Section 14.3. 

  
 53 













 9.3 Invalidation Proceedings. 

9.3.1 Notice. Each Party shall promptly notify the other Party of any declaratory judgment, opposition, inter partes review, or similar
action alleging the invalidity or unenforceability of any issued Perception Patent Rights, Joint Patent Rights or Otsuka Product Improvement Patents (“Invalidation Proceeding”) anywhere in the world of which such Party becomes
aware. 
 9.3.2 Perception Patent Rights. Otsuka shall have the first right, but not the obligation, to defend any Invalidation
Proceeding respecting the Perception Patent Rights in the Otsuka Territory. Perception shall have the sole right, but not the obligation, to defend any Invalidation Proceeding respecting the Perception Patent Rights in all countries other than the
Otsuka Territory. 
 9.3.3 Otsuka Product Improvement Patents. Otsuka shall have the sole right, but not the obligation, to defend any
Invalidation Proceeding respecting Otsuka Product Improvement Patents in the Otsuka Territory and shall have the first right, but not the obligation, to defend any Invalidation Proceeding respecting Otsuka Product Improvement Patents in any country
in the Perception Territory that is not a Perception Active Country. Perception shall have the first right, but not the obligation, to defend any Invalidation Proceeding respecting Otsuka Product Improvement Patents in all countries in the
Perception Territory in which Perception or any of its Sublicensees or Other Perception Licensees is Developing or Commercializing a Product (the “Perception Active Countries”). 

9.3.4 Joint Patent Rights. Otsuka shall have the first right, but not the obligation to defend any Invalidation Proceeding respecting
Joint Patent Rights in the Otsuka Territory. Perception shall have the first right, but not the obligation to defend any Invalidation Proceeding respecting Joint Patent Rights in the Mutually Selected Countries. Each Prosecuting Party that is
Prosecuting a Joint Patent Right in a country pursuant to Section 9.2.3(e) shall have the sole right, but not the obligation, to defend any Invalidation Proceeding respecting such Joint Patent Right in such country. 

9.3.5 Second Right to Defend. If the Party with the first right to defend in accordance with Section 9.3.2,
Section 9.3.3 or Section 9.3.4 does not inform the other Party that it intends to defend such an Invalidation Proceeding within [***] after a request from the other Party, and does not provide commercially reasonable
reasons why such Party does not intend to defend such Invalidation Proceeding, then the Party that does not have the first right to defend such Invalidation Proceeding will have the second right, but not the obligation, to defend such Invalidation
Proceeding at its cost and expense. For clarity, a Party’s second right to defend pursuant to this Section 9.3.5 shall not apply with respect to any Invalidation Proceeding that the other Party has the sole right to defend in
accordance with Section 9.3.2 or Section 9.3.3. 

  
 54 













 9.3.6 Collaboration. The Party defending any Invalidation Proceeding under
Section 9.3.2, Section 9.3.3, Section 9.3.4 or Section 9.3.5 (such Party, the “Defending Party”) shall have the right to control the defense of such Invalidation Proceeding, including
the right to select counsel therefor, [***]. The other Party (the “Supporting Party”) shall be entitled to separate representation in any Invalidation Proceeding by counsel of its own choice. At the Defending Party’s
request, the Supporting Party shall provide reasonable assistance to the Defending Party in connection with an Invalidation Proceeding [***]. The Defending Party shall keep the Supporting Party regularly informed of the status and progress of
such Invalidation Proceeding. In respect of any Invalidation Proceeding, the Defending Party shall provide the Supporting Party and its counsel with an opportunity to consult with the Defending Party and its counsel regarding the defense of such
Invalidation Proceeding (including reviewing the contents of any correspondence, legal papers or other documents related thereto), and the Defending Party shall take into account reasonable requests of the Supporting Party regarding such defense. In
no event shall the Defending Party settle any Invalidation Proceeding or take any other action that materially adversely affects the other Party’s rights or interests and, for clarity, the Defending Party may not admit invalidity or
unenforceability of any Patent Right Controlled by the other Party or any Joint Patent Right without the express prior written consent of the other Party. The terms of this Section 9.36 shall not apply with respect to any Invalidation
Proceeding which one Party has the sole right to defend in accordance with Section 9.3.2 or Section 9.3.3. 
 9.4
Patent Enforcement. 
 9.4.1 Notice. Each Party shall promptly notify the other Party of any known, suspected, alleged or
threatened infringement or misappropriation by a Third Party of any of the Perception Technology, Joint Technology, or Otsuka Product Improvements by reason of the making, using, offering to sell, selling or importing of any Product or any product
that is competitive with a Product in the Field (“Competing Infringement”) anywhere in the world of which such Party becomes aware. 

9.4.2 Otsuka First Enforcement Right. Otsuka shall have the first right, but not the obligation, to take any reasonable measures it
deems appropriate with respect to any Competing Infringement in the Otsuka Territory. Such measures may include (a) initiating or prosecuting an infringement suit or action (“Infringement Action”) in the Otsuka Territory, or
(b) granting adequate rights and licenses to such Third Party necessary to render continued Competing Infringement in the Otsuka Territory non-infringing. Notwithstanding the foregoing, if Otsuka does not
inform Perception that it intends to either initiate an Infringement Action in the Otsuka Territory or grant adequate rights and licenses to such Third Party within [***] after Otsuka’s receipt of a notice of a Competing Infringement
pursuant to Section 9.4.1 and does not provide Perception commercially reasonable reasons why Otsuka does not intend to initiate such Infringement Action or grant such rights or licenses within such [***] period, then Perception
will have the second right, but not the obligation, to initiate an Infringement Action in the Otsuka Territory, but solely with respect to any Perception Technology or Joint Technology. 

9.4.3 Perception First Enforcement Right. Perception shall have the first right, but not the obligation, to take any reasonable measures
it deems appropriate with respect to any Competing Infringement in the Perception Territory. Such measures may include (a) initiating or prosecuting an Infringement Action in the Perception Territory, or (b) granting adequate rights and


  
 55 













 
licenses to such Third Party necessary to render continued Competing Infringement in the Perception Territory non-infringing. Notwithstanding the
foregoing, if Perception does not inform Otsuka that it intends to either initiate an Infringement Action in the Perception Territory or grant adequate rights and licenses to such Third Party within [***] after Perception’s receipt of a
notice of a Competing Infringement pursuant to Section 9.4.1 and does not provide Otsuka commercially reasonable reasons why Perception does not intend to initiate such Infringement Action or grant such rights or licenses
within such [***] period, then Otsuka will have the second right, but not the obligation, to initiate an Infringement Action in the Perception Territory, but solely with respect to any Otsuka Product Improvement or Joint Technology. 

9.4.4 Collaboration. The Party initiating any Infringement Action under Section 9.4.2 or Section 9.4.3 (such
Party, the “Enforcing Party”) shall have the right to control the initiation and prosecution of such Infringement Action, including the right to select counsel therefor, [***]. The other Party (the “Non-Enforcing Party”) shall be entitled to separate representation in any Infringement Action under Section 9.4.2 or Section 9.4.3 by counsel of its own choice, except for any
Infringement Action solely related to Perception Technology in the Perception Territory. If requested by the Enforcing Party, the Non-Enforcing Party shall join as a party to such Infringement Action and will
execute all documents, including registration of exclusive license, necessary for the Enforcing Party to initiate, prosecute, maintain or defend such Infringement Action. Except with respect to any Infringement Action solely related to Perception
Technology in the Perception Territory, in respect of any Infringement Action: (a) at the Enforcing Party’s request, the Non-Enforcing Party shall provide reasonable assistance to the Enforcing Party
in connection with an Infringement Action [***]; (b) the Enforcing Party shall keep the Non-Enforcing Party regularly informed of the status and progress of an Infringement Action under
Section 9.4.2 or Section 9.4.3; and (c) in no event shall the Enforcing Party settle any Infringement Action or take any other action that materially adversely affects the other Party’s rights or interests and, for
clarity, the Enforcing Party may not admit invalidity or unenforceability of any Patent Right Controlled by the other Party or any Joint Patent Right without the express prior written consent of the other Party. For clarity, Perception may settle
any Infringement Action or take any other action while prosecuting an Infringement Action, in each case, to the extent relating to Perception Technology in the Perception Territory without the express prior written consent of Otsuka. 

9.4.5 Recoveries. If an Enforcing Party recovers monetary damages in an Infringement Action under Section 9.4.2 or
Section 9.4.3, such recovery shall be allocated first to the reimbursement of any expenses incurred by the Enforcing Party in connection with such Infringement Action, second to the reimbursement of any expenses incurred by the other
Party in connection with such Infringement Action, and any remaining amounts shall be retained by [***]; provided that if Otsuka is the Enforcing Party, then any remaining amounts awarded to Otsuka as compensation for lost sales shall be
[***]. 
 9.4.6 Sole Enforcement Right. Notwithstanding the above, the Party that is Prosecuting a Joint Patent Right in a
country pursuant to Section 9.2.3(e) shall have the sole right, but not the obligation, [***], to initiate an Infringement Action or take any other reasonable measures it deems appropriate with respect to any Competing Infringement with
respect to such Joint Patent Right in such country, and the terms of Section 9.4.2, Section 9.4.3, Section 9.4.4 and Section 9.4.5 shall not apply to such Infringement Action; provided that the Prosecuting Party
shall 

  
 56 













 
not settle any Infringement Action with respect to any such Joint Patent Right or take any other action that materially adversely affects the other Party’s rights or interests with respect
to any such Joint Patent Right and, for clarity, the Prosecuting Party may not admit invalidity or unenforceability of any Patent Right Controlled by the other Party or any Joint Patent Right without the express prior written consent of the other
Party. [***] 
 9.5 Third Party Infringement Claims. If a Third Party sues a Party (the “Sued Party”) alleging
that the Sued Party’s, or the Sued Party’s Sublicensee’s, Development, Manufacture or Commercialization of any Product in the Otsuka Territory infringes or will infringe such Third Party’s Patent Rights or misappropriates or will
misappropriate such Third Party’s Know-How (“Third Party Infringement Suit”), then the Sued Party shall promptly notify the other Party of such Third Party Infringement Suit. The Parties
shall promptly meet to consider the appropriate course of action and may, if appropriate, agree on and enter into a “common interest agreement” wherein the Parties agree to their shared, mutual interest in the outcome of such Third Party
Infringement Suit. Absent such agreement, the Sued Party shall defend the Third Party Infringement Suit; provided that Section 9.4 shall govern the right of Otsuka to assert a counterclaim of infringement of any Perception
Patent Rights, Joint Patent Rights or Otsuka Product Improvement Patents. At the Sued Party’s request [***], the other Party will provide reasonable assistance to the Sued Party in connection with the Sued Party’s defense of any
such Third Party Infringement Suit. If the other Party has not joined in such Third Party Infringement Suit, the Sued Party will keep the other Party reasonably informed on a Calendar Quarter basis prior to and during the pendency of such Third
Party Infringement Suit. The Sued Party will not enter into any settlement of any Third Party Infringement Suit that is instituted or threatened to be instituted against the other Party without the other Party’s prior written consent, which
will not be unreasonably withheld, conditioned or delayed; except that, such consent will not be required if such settlement includes a release of all liability in favor of the other Party. Further, the Sued Party shall not settle or compromise any
Third Party Infringement Suit, or knowingly take any other action in the course thereof, in a manner that materially adversely affects the other Party’s rights or interests, without the prior written consent of such other Party, such consent
not to be unreasonably withheld, conditioned or delayed. [***]. If, as part of a settlement or compromise of a Third Party Infringement Suit, Otsuka enters into an agreement with a Third Party to obtain a license under or otherwise acquire
rights to Third Party Intellectual Property Rights, all payments by Otsuka to such Third Party under such agreement (including all upfront payments, milestone payments, license fees, royalties and other amounts payable to such Third Party for such
rights) may be applied to the royalty reduction pursuant to Section 8.4.3(c). 
 9.6 Patent Oppositions
and Other Proceedings. If either Party desires to initiate in any court or patent office an opposition, action for declaratory judgment, nullity action, interference, declaration for non-infringement,
reexamination or other attack upon the validity, title or enforceability of a Patent Right owned or controlled by a Third Party and having one or more claims that may cover the API or a Product, or the manufacture, use, sale, offer for sale or
importation of the API or a Product (except insofar as such action is a counterclaim to or defense of, or accompanies a defense of, (a) a Third Party’s claim or assertion of an Invalidation Proceeding, in which case the provisions of
Section 9.3 shall govern or (b) a Third Party Infringement Suit, in which case the provisions of Section 9.5 shall govern), such Party shall so notify the other Party and the Parties shall
promptly confer to determine whether to bring such action. If the Parties do not agree otherwise then, as between the Parties, (i) Otsuka shall have the sole right to control such action with regard to the Otsuka Territory and [***] and
(ii) Perception shall have the sole right to control such action [***] with regard to the Perception Territory, and the Party so controlling such action shall keep the other Party reasonably informed with respect thereto.

 9.7 Third Party Intellectual Property Rights. 

9.7.1 Chiba University Agreement. Perception shall remain responsible for the payment of all royalties, license fees, milestone payments
and other payment obligations under all agreements with Third Parties entered into by Perception prior to the Effective Date pursuant to which Perception obtained rights to any Third Party Know-How, Third
Party Patent Rights or other Third Party Intellectual Property Rights that are necessary or reasonably useful to Develop, Manufacture, Commercialize or otherwise exploit API or any Product, including all payments under the Chiba University
Agreement. 
 9.7.2 Notice; Discussion. Each Party shall promptly notify the other Party if it becomes aware after the Effective Date
of any Third Party Know-How or Third Party Patent Rights that are necessary or reasonably useful to Develop, Manufacture or Commercialize any Product in the Field (“Third Party IP”).
Thereafter, the Parties shall discuss whether to obtain a license or otherwise acquire rights under such Third Party IP for one or the other Party’s Territory or for both Parties’ Territories. 

9.7.3 Global Third Party IP Agreement. If the Parties agree to obtain a license or otherwise acquire rights from a Third Party under
Third Party IP to Develop, Manufacture or Commercialize a Product in both the Perception Territory and the Otsuka Territory (“Global Third Party IP Agreement”), Perception shall have the right to negotiate such Global Third Party IP
Agreement with such Third Party. Perception shall negotiate such Global Third Party IP Agreement on commercially reasonable terms that shall not favor the Perception Territory or disproportionately burden the Otsuka Territory. Perception shall
ensure that such Global Third Party IP Agreement includes the right to sublicense to Otsuka in the Otsuka Territory in order for Otsuka to exercise its rights and licenses hereunder. If the Parties agree and Perception enters into a Global Third
Party IP Agreement, Otsuka shall reimburse Perception for all payments made by Perception under such Global Third Party IP Agreement that are attributable to Net Sales of a Product in the Otsuka Territory or otherwise are allocable to such Product
in the Otsuka Territory, including any upfront, milestone, royalty payment or other similar payment (such payments collectively, the “Global Third Party IP Payments”), and Perception shall be responsible for all other payments under
such Global Third Party IP Agreement; provided that for any such Global Third Party IP Payments for a Calendar Year that are not Otsuka Territory-specific milestones or royalty payments on Net Sales in the Otsuka Territory, the Parties will discuss
in good faith and agree on [***] for such payments. If the Parties are unable to agree upon such [***] within [***] after the commencement of such discussions (or such longer period as the Parties may agree), then the matter shall be subject
to resolution in accordance with Section 14.3. 
 9.7.4 Other Third Party IP Agreement. If the Parties do not agree to
obtain a license or otherwise acquire rights under a Global Third Party IP Agreement, then either Party may negotiate with a Third Party to obtain a license or otherwise acquire rights under Third Party IP to Develop, Manufacture or Commercialize a

 9.8 Common Interest. All information exchanged between the Parties’
representatives pursuant to this Article 9 regarding the Prosecution, defense or enforcement of Patent Rights will be deemed Confidential Information. The Parties agree and acknowledge that they have not waived, and nothing in this Agreement
constitutes a waiver of, any legal privilege concerning such Patent Rights, including privilege under the common interest doctrine and similar or related doctrines. 

9.9 Patent Term Extensions. Otsuka shall have the sole right to make decisions regarding, and to apply for, all available
extensions of Perception Patent Rights (in the name of Perception), Otsuka Product Improvement Patents and Joint Patent Rights in the Otsuka Territory; provided, that, with respect to the Perception Patent Rights and Joint Patent Rights, upon
Otsuka’s request, Perception shall use Commercially Reasonable Efforts to obtain any such available extension in the Otsuka Territory, as requested by Otsuka, and [***]. Perception shall have the sole right to make decisions regarding,
and to apply for, all available extensions of Perception Patent Rights, Otsuka Product Improvement Patents (in Otsuka’s name) and Joint Patent Rights in the Perception Territory; provided, that, with respect to the Otsuka Product Improvement
Patents, upon Perception’s request, Otsuka shall use Commercially Reasonable Efforts to obtain any such available extension in the Perception Territory, as requested by Perception, provided that [***]. 

9.10 Product Trademarks. 

9.10.1 Product Trademarks. Perception shall develop and adopt Trademarks to be used for the Products (the “Product
Trademarks”) and Perception shall use Commercially Reasonable Efforts to obtain and maintain a unitary Product Trademark for use worldwide. If Perception is unable to obtain or maintain a unitary Product Trademark for use worldwide or if
Perception is unable to obtain or maintain any Product Trademarks in the Otsuka Territory, Otsuka may either select from the secondary Product Trademarks registered by Perception in accordance with Section 9.10.2 or develop and adopt
Trademarks to be used for the Products in the Otsuka Territory. In addition, if Otsuka reasonably believes that any Product Trademarks developed and adopted by Perception are not appropriate for the Otsuka Territory, whether due to linguistic
reasons, any notice (including rejection or refusal) by a Regulatory Authority in the Otsuka Territory, market research showing that the Product Trademarks are not appropriate for commercial use in the Otsuka Territory, or otherwise, Otsuka may
either select from the secondary Product Trademarks registered by Perception in accordance with Section 9.10.2 or develop and adopt an alternative Trademark for Products in the Otsuka Territory with the consent of Perception (not to be
unreasonably withheld, conditioned or delayed). In addition, Otsuka may develop and adopt a katakana Trademark, which is a Japanese notation of a Trademark to be used in the Otsuka Territory, and any additional Trademarks (e.g., logos and slogans)
to be used in the Commercialization of Products in the Otsuka Territory with the consent of Perception (not to be unreasonably withheld, conditioned or delayed). Any such alternative Trademark, katakana Trademark or additional Trademark adopted by
Otsuka shall be a Product Trademark and shall be registered by Perception and Perception shall prosecute such Product Trademark in accordance with Section 9.10.2. 

  
 59 













 9.10.2 Prosecution of Product Trademarks. Perception shall own all rights, title and
interest in and to all Product Trademarks, and all goodwill in the Product Trademarks shall inure to Perception. Otsuka shall use Product Trademarks in a manner consistent with this Agreement, including the Global Branding Strategy or Otsuka
Territory-Specific Brand Strategy, as applicable, and for no other purpose. Otsuka shall not use any other Trademarks that are confusingly similar to any Product Trademark. Perception shall be responsible, [***], for the filing, prosecution,
registration and maintenance (including the defense of opposition proceedings and any equivalent proceedings) of all Product Trademarks, including at least one primary Product Trademark and at least two secondary Product Trademarks and including the
katakana Trademark, in a timely manner in the Otsuka Territory throughout the Term; provided, that in the event Otsuka develops and adopts an alternative Product Trademark for the Otsuka Territory as described in Section 9.10.1 (for
clarity, other than the katakana Trademark or any secondary Product Trademark selected by Otsuka), then [***]. Perception shall keep Otsuka informed of material progress with regard to the prosecution, registration, and maintenance of Product
Trademarks in the Otsuka Territory, including content and timing of the filing of Product Trademarks in the Otsuka Territory, sufficiently in advance for Otsuka to be able to review any material documents, and Perception shall consult with, and
consider in good faith the comments, requests and suggestions of, Otsuka with respect to strategies for filing and prosecuting Product Trademarks in the Otsuka Territory. 

9.10.3 Enforcement of Product Trademarks. During the Term, each Party will promptly notify the other Party in writing of any known or
suspected infringement or unauthorized use or misappropriation by a Third Party of any Product Trademarks in the Otsuka Territory (“Product Trademark Infringement”). Otsuka shall have the first right, but not the obligation, to take
any reasonable measures it deems appropriate with respect to any Product Trademark Infringement, [***], including initiating or prosecuting an infringement, misappropriation or other appropriate suit or action to enforce the Product
Trademarks in the Otsuka Territory and, if requested by Otsuka, Perception shall (a) join as a party to such suit or action and execute and cause its Affiliates to execute all documents necessary for Otsuka to initiate and maintain such suit or
action and (b) provide reasonable assistance to Otsuka in connection with such suit or action. Notwithstanding the foregoing, if Otsuka does not inform Perception that it intends to initiate a suit or take other action against Product Trademark
Infringement within [***] after Otsuka’s receipt of a notice of such Product Trademark Infringement and does not provide Perception commercially reasonable reasons why Otsuka does not intend to initiate such suit or take such other
action within such [***] period, then Perception will have the second right, but not the obligation, to initiate a suit or take other action against such Product Trademark Infringement. 

9.10.4 Defense. If a Third Party brings suit alleging that a Sued Party’s or its Sublicensee’s Development, Manufacture or
Commercialization of a Product in the Otsuka Territory infringes or will infringe such Third Party’s Trademarks (“Trademark Infringement Suit”), then the Sued Party shall promptly notify the other Party of such Trademark
Infringement Suit and Otsuka shall be responsible, [***], for the defense of such Trademark Infringement Suit. At Otsuka’s request [***], Perception will provide reasonable assistance in connection with Otsuka’s defense of
such Trademark Infringement Suit and Otsuka will keep Perception reasonably informed on a Calendar Quarter basis prior to and during the pendency of such Trademark Infringement Suit. Otsuka will not enter into any settlement of any Trademark
Infringement Suit that is instituted or threatened to be instituted against Perception without 

  
 60 













 
Perception’s prior written consent, which will not be unreasonably withheld, conditioned or delayed; provided that such consent will not be required if such settlement includes a release of
all liability in favor of Perception. Further, Otsuka shall not settle or compromise any Trademark Infringement Suit, or knowingly take any other action in the course thereof, in a manner that materially adversely affects Perception’s rights or
interests, without Perception’s prior written consent. 
 9.10.5 Guidelines for Use. Otsuka shall use, and shall cause its
Sublicensees to use, best efforts to ensure (a) that the nature and quality of all Products and of all Promotional Materials and all other materials, whether in print, electronic or other form, bearing the Product Trademarks and product
labeling shall be of a high standard and of such style, appearance and quality as to be adequate and suited to the exploitation to the best advantage, and to the protection and enhancement, of the Product Trademarks and the goodwill pertaining
thereto, and (b) that all uses of the Product Trademarks by Otsuka and its Sublicensees shall comply with all (i) trademark usage guidelines and notices Perception may provide to Otsuka in writing from time to time with respect to the use
of such Product Trademarks and (ii) Applicable Laws (collectively, “Quality Standards”). Upon Perception’s request, Otsuka shall promptly provide Perception with representative samples of any and all uses and materials
bearing the Product Trademarks as well as sufficient information regarding the specific Products offered under the Product Trademarks to enable Perception to evaluate Otsuka’s and its Sublicensees’ use of the Product Trademarks and the
quality of such Products and materials.

necessary or useful in connection with the exploitation of any Product in such Party’s Territory or as may otherwise be reasonably required in order for such Party to perform its obligations, or to exploit it rights, under this Agreement, in
each case who are under an obligation of confidentiality with respect to such information that is no less stringent than the terms of this Section 10.1; (b) Governmental Authorities or other Regulatory Authorities in any country, in

which the Parties may publish certain key results achieved in connection with this Agreement, including in connection with Development of the Products in the Otsuka Territory, that will be coordinated with the publication by Perception of similar
results achieved with respect to such activities in the Perception Territory, with the goal of protecting the Parties’ ability to obtain Patent Rights with respect to such activities as applicable,


  
 62 













 
and to position the Products for Regulatory Approval and successful Commercialization in the Parties’ respective Territories. All publications of such key results shall be consistent with
such publication strategy and shall be subject to this Section 10.2.1. Except for disclosures permitted pursuant to Section 10.1 and Section 10.2.2, if a Party desires to

non-publishing Party, and (b) to request a reasonable delay in publication or presentation in order to protect patentable information. If the non-publishing Party
requests a delay, the publishing Party shall delay submission or presentation for a period of [***] days to enable the non-publishing Party to file patent applications protecting such Party’s

Parties and their parent entities (and with respect to Perception, its investors) may (a) once a press release or other public statement is approved in writing by both Parties, make subsequent public disclosure of the existence of this
Agreement, the identity of the other Party, and those terms of this Agreement that have already been publicly disclosed, without the further approval of the other Party, and (b) issue a press release or public announcement as required, in the

Perception. Perception shall indemnify, hold harmless, and defend Otsuka, its Sublicensees and its and their respective directors, officers, employees and agents (“Otsuka Indemnitees”) from and against any and all Losses to
which any Otsuka Indemnitee may become subject as a result of any Third Party Claim to the extent such Third Party Claim or Losses arise out of: (a) the Development, Manufacture or Commercialization of any Product by Perception, Other
Perception Licensees or subcontractors during the Term or after termination or expiration of this Agreement (excluding the Manufacture of API or Clinical Samples supplied by Perception to Otsuka under the Supply Agreement), (b) any breach of, or
inaccuracy in, any representation or warranty made by Perception in this Agreement, or any breach or violation of any covenant or agreement of Perception in or in the performance of this Agreement, or (c) the negligence or willful misconduct by
Perception or its Sublicensees or subcontractors, including CMOs, or their respective directors, officers, employees or agents (i) in the performance of Perception’s obligations under this Agreement or (ii) in the Development or
Manufacture of any Product prior to the Effective Date; provided that, Perception shall have no 

  
 69 













 
obligation to indemnify the Otsuka Indemnitees to the extent that the Losses arise out of or result from any matters for which Otsuka is obligated to indemnify Perception under
Section 12.1. For clarity, Perception’s obligations to indemnify Otsuka with respect to API or Clinical Samples supplied by Perception to Otsuka shall be as set forth in the Supply Agreement. 

12.3 Procedure. In the event of a Third Party Claim against any Otsuka Indemnitee or Perception Indemnitee (individually, an
“Indemnitee”), the Party seeking indemnification under this Article 12 (the “Indemnified Party”) shall promptly notify the other Party (the “Indemnifying Party”) in writing of such Third
Party Claim; provided that any failure or delay in providing such notice will not relieve the Indemnifying Party of its indemnification obligation, except to the extent it is actually prejudiced by such failure or delay. The Indemnitee will
reasonably cooperate with the Indemnifying Party and may, at its option, be represented in such action or proceeding at its cost and expense; provided that if an Indemnitee retains its own counsel for the reason that representation of such
Indemnitee by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between the Indemnitee and any other party represented by such counsel in such action or proceeding, then the
Indemnifying Party shall pay the fees and expenses of the Indemnitee’s counsel. The Indemnifying Party will have the right to assume and control the defense of the Third Party Claim at its own expense with counsel selected by the Indemnifying
Party and reasonably acceptable to the Indemnified Party. If the Indemnifying Party does not assume the defense of the Third Party Claim pursuant to this Section 12.3, then the Indemnified Party may defend the Third Party Claim but will
have no obligation to do so. Each Party will promptly furnish to the other Party copies of all papers and official documents received in respect of any Losses. The Indemnified Party will not settle or compromise the Third Party Claim without the
prior written consent of the Indemnifying Party, and the Indemnifying Party will not settle or compromise the Third Party Claim in any manner that would have an adverse effect on the Indemnified Party’s interests (including any rights under
this Agreement or the scope, validity, or enforceability of any Patent Rights, Confidential Information, or other rights licensed to Otsuka by Perception hereunder), without the prior written consent of the Indemnified Party. 

12.4 Limitation of Liability. NEITHER PARTY HERETO SHALL BE LIABLE FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES
ARISING OUT OF THIS AGREEMENT OR THE EXERCISE OF ITS RIGHTS OR PERFORMANCE OF ITS OBLIGATIONS HEREUNDER, INCLUDING LOST PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF SUCH DAMAGES, EXCEPT AS A RESULT OF
A PARTY’S WILLFUL MISCONDUCT OR A BREACH OF ARTICLE 10 OR THE EXCLUSIVITY TERMS OF THE LICENSES GRANTED IN ARTICLE 2. NOTHING IN THIS SECTION 12.4 IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS
OF EITHER PARTY. 
 13. TERM AND TERMINATION 

13.1 Term. This Agreement shall be effective as of the Effective Date and, unless terminated earlier pursuant to
Section 13.2, this Agreement shall continue in effect, on a Product-by-Product basis until the expiration of the Royalty Term for such Product
(“Term”). Upon the expiration of the Term with respect to a Product (without this Agreement being terminated earlier pursuant to Section 13.2), Otsuka’s rights to such Product and all license grants to Otsuka
hereunder with respect to such Product shall continue, shall remain exclusive to Otsuka (even as to Perception) and shall become fully paid-up, royalty-free, perpetual and irrevocable. 

  
 70 













 13.2 Early Termination. This Agreement may not be terminated by either Party
except as provided in this Section 13.2. 
 13.2.1 Termination by Otsuka. Otsuka shall have the right to terminate this
Agreement in its entirety for convenience at any time (a) on [***] prior written notice to Perception if such notice is given before the first Regulatory Approval of the first Product in the Otsuka Territory, or (b) on [***]
prior written notice to Perception if such notice is given on or after the first Regulatory Approval of the first Product in the Otsuka Territory. 

13.2.2 Suspension / Termination for Safety. Otsuka shall have the right to immediately suspend its activities under this Agreement due
to (a) any Safety Reasons, (b) failure of any Clinical Study for any Product in the Otsuka Territory or the Perception Territory or (c) withdrawal of Regulatory Approval for any Product in the Perception Territory; provided that
Otsuka shall immediately inform Perception of such suspension and, in the case of clause (a), Otsuka shall request a meeting of the JCC to discuss such Safety Reason. Otsuka shall have the right to terminate this Agreement in its entirety due
to (a) any Safety Reasons, (b) failure of any Clinical Study for any Product in the Otsuka Territory or the Perception Territory or (c) withdrawal of Regulatory Approval for any Product in the Perception Territory immediately upon
written notice to Perception, provided that Otsuka shall not give such notice of termination until after discussion at the JCC with respect thereto. 

13.2.3 Termination for Cause. This Agreement may be terminated in its entirety at any time during the Term upon written notice by either
Party if the other Party is in material breach of its obligations hereunder and has not cured such breach within [***] in the case of a payment breach, or within [***] in the case of all other breaches, after notice requesting cure of
the breach; provided that, if any breach other than a payment breach is not reasonably curable within [***] and if a Party is making a bona fide effort to cure such breach, such termination shall be delayed for a time period to be agreed by
both Parties, not to exceed an additional [***], in order to permit such Party a reasonable period of time to cure such breach. Notwithstanding the foregoing, if the allegedly breaching Party disputes in good faith the existence, materiality,
or failure to cure of any breach, and provides written notice to the other Party of such dispute within the relevant cure period, the other Party will not have the right to terminate this Agreement in accordance with this Section 13.2.3
unless and until the relevant dispute has been resolved pursuant to Article 14. During the pendency of such dispute, the applicable cure period will be tolled, all the terms of this Agreement will remain in effect, and the Parties will
continue to perform all of their respective obligations hereunder. 
 13.2.4 Termination for Cessation of Development and
Commercialization. 
 (a) Subject to Section 13.2.4(b), if Otsuka has ceased all material Development and
Commercialization activities in the Otsuka Territory with respect to all Products for [***] and such cessation is not the result of a force majeure event, Good Reason, a delay in response from a Regulatory Authority, a failure or delay in
Perception’s performance of its obligations under this Agreement or the Supply Agreement, or customary pauses or gaps between 

  
 71 













 
or following Clinical Studies and Non-Clinical Studies for the analysis of data, preparation of reports and design of future clinical trials or preparation
of regulatory filings and other customary regulatory or Development functions, then Perception may terminate this Agreement on [***] written notice to Otsuka given no later than [***] after the end of such [***]. For purposes of
this Section 13.2.4, “Good Reason” means a Safety Concern or other material scientific, technical, commercial, or regulatory reason (for example a clinical hold being placed on a Product, a material drug
manufacturing problem or a material data problem such as a serious toxicology or pharmacokinetics issue) that would be reasonably expected to impede or significantly delay a product advancing through Development or Commercialization, but if a Good
Reason is invoked by Otsuka as a reason to stop or hold Development or Commercialization, then Otsuka shall use Commercially Reasonable Efforts to resolve the problem(s) that is the basis of such Good Reason. 

(b) Notwithstanding the foregoing in Section 13.2.4(a), if Perception provides a termination notice pursuant to
Section 13.2.4(a) and Otsuka disputes in good faith whether Perception has the right to terminate the Agreement pursuant to Section 13.2.4(a) and provides written notice to Perception of such
dispute within the [***] notice period, Perception will not have the right to terminate this Agreement in accordance with this Section 13.2.4 unless and until the relevant dispute has been resolved pursuant to
Article 14. During the pendency of such dispute all the terms of this Agreement will remain in effect, and the Parties will continue to perform all of their respective obligations hereunder. 

13.2.5 Bankruptcy. If the performance of a Party’s obligations under this Agreement become untenable as a result of such Party (or
an Affiliate that controls such Party) filing of a petition in bankruptcy or entering into insolvency or liquidation proceedings either voluntarily or involuntarily, or if a receiver is appointed with respect to the assets of such Party (or its
Affiliate, if applicable), or any similar action is filed under Applicable Laws, and such measure is not dismissed within [***], to the extent permitted by the Applicable Laws of such Party’s Territory, the other Party may terminate this
Agreement immediately upon written notice to such Party. Notwithstanding the foregoing, the Parties acknowledge that a Party to this Agreement may from time-to-time make
changes in its corporate structure, including, inter alia, changes in the shareholdings of Affiliates, which would not constitute a case of bankruptcy under this Section 13.2.5. 

13.3 Effects of Termination. 

13.3.1 General Consequences of Termination or Expiration. If this Agreement expires or is terminated by a Party prior to its expiration,
in each case, in its entirety at any time and for any reason, then the terms of this Section 13.3.1 will apply. 

13.3.2 License Grants. Upon termination of this Agreement under Section 13.2 prior to expiration (for clarity,
not if this Agreement expires pursuant to Section 13.1), all rights and licenses granted to Otsuka under Section 2.1 and to Perception under Section 2.2 will terminate and
Otsuka and its Sublicensees will cease selling Products, except in each case to the extent necessary or reasonably useful for Otsuka to perform Transition Activities pursuant to Section 13.3.5 or to sell Products
post-termination pursuant to Section 13.3.5(e). 

  
 72 













 13.3.3 Reversion License. 

(a) Upon termination of this Agreement under Section 13.2 prior to expiration (for clarity, not if this Agreement
expires pursuant to Section 13.1), Otsuka shall, and hereby does, effective as of the effective date of termination, grant Perception (i) a worldwide, royalty-free (subject to the proviso below) exclusive license under
the Otsuka Product Improvements and Otsuka’s interest in the Joint Technology solely to Develop, have Developed, Manufacture, have Manufactured, Commercialize and otherwise exploit any Product worldwide, (ii) a non-exclusive, royalty-bearing license under any Patent Rights Controlled by Otsuka to the extent such Patent Rights are (A) used by Otsuka or its Affiliates or their respective (sub)licensees in the
Development, Manufacture, Commercialization or other exploitation of a Product as it exists as of the effective date of termination and (B) necessary to Develop, have Developed, Manufacture, have Manufactured, Commercialize or otherwise exploit
any Product as it exists in the Otsuka Territory as of the effective date of termination, but excluding any Other Product Otsuka Termination Patent Rights (such Patent Rights, the “Otsuka Termination Patents”) solely to Develop,
have Developed, Manufacture, have Manufactured, Commercialize and otherwise exploit any Product as it exists in the Otsuka Territory as of the effective date of termination (or minor modifications thereof), and (iii) a non-exclusive, royalty-bearing license under any Know-How Controlled by Otsuka or any of its Affiliates (that is not an Otsuka Product Improvement or Joint Technology) to the
extent such Know-How is necessary for, and used by Otsuka or its Affiliates or its or their respective (sub)licensees in, the Manufacture of a Product (that is not a Combination Product) as it exists in the
Otsuka Territory as of the effective date of termination (such Know-How, the “Otsuka Termination Know-How”) solely to Manufacture or have Manufactured
such Product as it exists in the Otsuka Territory as of the effective date of termination (the licenses granted under (i), (ii) and (iii), the “Reversion License”); provided that if this Agreement is terminated by Otsuka pursuant to
Section 13.2.3 or Section 13.2.5, the license grant under clause (i) of the Reversion License shall be royalty-bearing as well. Perception shall pay Otsuka a commercially reasonable royalty
under the Reversion License on Net Sales of Products taking into account the then-current stage of any Products, the relative value of the Otsuka Termination Patents and Otsuka Termination Know-How and, if
applicable, the Otsuka Product Improvements and Joint Technology and the reason for termination, on terms to be agreed between Perception and Otsuka, and the grant of such license shall be conditioned on the Parties determining such royalty
(including through dispute resolution, if applicable). If the Parties are unable to agree upon a commercially reasonably royalty within [***] after the effective date of termination (or such longer period as the Parties may agree), then such
royalty amount shall be subject to resolution in accordance with Section 14.3. 
 (b) With respect to any Otsuka
Termination Patent or Otsuka Termination Know-How that is in-licensed by Otsuka, (i) Otsuka shall provide a copy of the relevant
in-license agreement (each, an “Otsuka Termination IP In-License Agreement”) to Perception timely after the effective date of such termination of this
Agreement, and (ii) upon the election of Otsuka, either (A) Otsuka shall assign such Otsuka Termination IP In-License Agreement to Perception and Perception shall accept such assignment (in which
case the applicable Otsuka Termination Patent or Otsuka Termination Know-How shall not be included within the scope of the Reversion License) or (B) (1) the Reversion License shall be subject to the terms
and conditions of such Otsuka Termination IP In-License Agreement, (2) Perception shall make any payments (including royalties, milestones, and other amounts) payable by Otsuka to


  
 73 













 
Third Parties under any Otsuka Termination IP In-License Agreements that are the subject of the Reversion License, by making such payments directly to
Otsuka and, in each instance, Perception shall make the requisite payments to Otsuka and provide the necessary reporting information to Otsuka in sufficient time to enable Otsuka to comply with its obligations under such Otsuka Termination IP In-License Agreements, (3) Perception shall not, and shall cause its Affiliates, Sublicensees and Other Perception Licensees not to, take or fail to take any action if doing so (or not doing so) would cause
Otsuka to be in breach of any Otsuka Termination IP In-License Agreement and (4) Otsuka shall be responsible for paying or providing to any such Third Party any payments or reports made or provided by
Perception under this Section 13.3.3(b). 
 13.3.4 Assignments. Upon termination of this Agreement under
Section 13.2 prior to expiration (for clarity, not if this Agreement expires pursuant to Section 13.1), as soon as practicable after the effective date of termination, or in accordance with
timelines set forth in any transition plan for Transition Activities that the Parties agree upon pursuant to Section 13.3.5 (if applicable), unless Perception informs Otsuka that Perception will not (itself or with or
through its Affiliate or a Third Party) continue Development or Commercialization of any Product in the Otsuka Territory (e.g., if this Agreement is terminated due to Safety Reasons), Otsuka shall transfer and assign to Perception or its designee:
(a) all Regulatory Documentation for the Products for the Otsuka Territory (or in the case of Combination Products, all such Regulatory Documentation controlled by Otsuka), including any Regulatory Approvals, NHI Price Listing and
pharmacovigilance files that relate to the Products; (b) all of Otsuka’s right, title, and interest in and to all Product Trademarks and all domain names associated with the Product Trademarks (if any, to the extent that they are owned by
Otsuka), (c) at Perception’s option, distribution agreements, confidentiality agreements, Clinical Study agreements and other agreements (in each case to the extent assignable and not cancelled) to which Otsuka is a party, in each case, that
are specific to a Product and necessary or reasonably useful for the continued Development or Commercialization of such Product in the Otsuka Territory; provided that with respect to any such agreements that (i) relate to such Product, but are
not specific to such Product or (ii) are specific to such Product but are not fully assignable to Perception (or its designee), Otsuka shall use Commercially Reasonable Efforts to partially assign to Perception (or its designee(s)) such
agreement with respect to such Product or, if such partial assignment is not possible, Otsuka shall use Commercially Reasonable Efforts to provide Perception with an introduction to the applicable counterparty to such agreement and facilitate
negotiations with such counterparty; and (d) any other materials necessary to reasonably facilitate an efficient transfer of the distribution of Products in the Otsuka Territory to Perception (or its designee). 

13.3.5 Transition Activities. Upon termination of this Agreement under Section 13.2 except if this Agreement
is terminated by Otsuka pursuant to Section 13.2.3 (for clarity, not if this Agreement expires pursuant to Section 13.1): 

(a) The Parties wish to provide a mechanism to ensure that, assuming any Product is available to patients in the Otsuka Territory as of the
effective date of termination, patients who were being treated with Products prior to such termination or who desire access to a Product can continue to have access to such Products while the responsibilities for any Product in the Otsuka Territory
are transitioned from Otsuka to Perception or its designee. 

  
 74 













 (b) As such, Perception may request Otsuka to perform transition activities with respect to
Products in the Otsuka Territory that are necessary or reasonably useful to (i) transition Commercialization activities (if any) to Perception, including transitioning distribution responsibilities to Perception or its designee, to avoid any
shortage of Products and minimize disruption to sales in the Otsuka Territory, (ii) provide patients with continued access to Products (if applicable), (iii) enable Perception or its designee to assume and execute the responsibilities under all
Regulatory Approvals and ongoing Clinical Studies for Products in the Otsuka Territory, and (iv) ensure long-term continuity of supply of Products in the Otsuka Territory (collectively, the “Transition Activities”). 

(c) If, within [***] after the effective date of termination, Perception provides a written request to Otsuka to perform Transition
Activities in the Otsuka Territory, then the Parties will mutually agree on a transition plan for Otsuka to perform such Transition Activities (and neither Party shall unreasonably withhold its agreement to such transition plan), including
transition dates, and, to the extent permitted under Applicable Law, Otsuka will conduct such Transition Activities in accordance with such plan, but in no event for longer than [***] following the effective date of termination. In addition,
the Parties will establish a transition committee consisting of at least each Party’s Alliance Manager, and up to [***] additional representatives from each Party who are from other relevant functional groups to facilitate a smooth
transition, and the Parties will mutually agree on talking points and a communication plan to customers, physicians, Regulatory Authorities, patient advocacy groups, and Clinical Study investigators, in each case only if applicable at the time of
termination, and Otsuka will make such communications to such applicable entities in accordance with the mutually agreed talking points. As part of the Transition Activities, Otsuka will cooperate with all reasonable requests of Perception relating
to the transition to Perception or its designee of activities relating to any Product in the Otsuka Territory and, at Perception’s request, Otsuka shall provide Perception with reasonable assistance with any inquiries and correspondence with
Regulatory Authorities in the Otsuka Territory regarding the Products. 
 (d) [***]. 

(e) Distribution and Sale of Inventory. In order to avoid any shortage of Products in the Otsuka Territory, if Perception requests that
Otsuka perform Transition Activities and Otsuka did not terminate this Agreement pursuant to Section 13.2.2, Otsuka shall continue to distribute Products in the Otsuka Territory and, to the extent Otsuka’s then-existing inventory of
Products is insufficient to fulfill sales of Products in the Otsuka Territory, Otsuka shall continue to Manufacture Products for sale and distribution in the Otsuka Territory for a period of up to [***] after the effective date of
termination; provided that Perception shall pay Otsuka its fully burdened costs to Manufacture such Products (including Otsuka’s then-existing inventory and any additional Products Manufactured by Otsuka for distribution in connection with the
Transition Activities), plus a mark-up of [***]. If Perception does not request Otsuka to perform the Transition Activities, Otsuka shall have the right to
sell-off its inventory of Products (“Inventory Sell-Off”) until the earlier of (i) such time as Perception or its designee is able to assume
responsibility for distribution of Products in the Otsuka Territory or (ii) the date on which the Regulatory Approvals for Products in the Otsuka Territory are transferred and assigned to Perception or its designee (the earlier of (i) or
(ii), the “Distribution End Date”). In the event of Inventory Sell-Off (as opposed to distribution as part of the Transition Activities), Otsuka shall


  
 75 













 
retain all revenues from sales of such inventory of Products through the Distribution End Date, provided that Otsuka shall continue to pay any royalties due on such Net Sales pursuant to
Section 8.4. As soon as practicable following the Distribution End Date (in the event of Inventory Sell-Off) or as soon as practicable following completion of Transition Activities,
if applicable, Otsuka shall, as instructed by Perception in writing, either destroy or deliver to Perception all of Otsuka’s remaining inventory of Products, and Perception shall reimburse Otsuka for such inventory at a price equal to
Otsuka’s fully burdened costs to Manufacture such inventory, plus a mark-up of [***]. For clarity, Otsuka shall have no obligation to recover any Products sold to customers, including Distributors
and wholesalers, prior to the Distribution End Date or prior to completion of the Transition Activities. 
 (f) Technology Transfer.
Otsuka shall, upon Perception’s reasonable request and [***], (i) effect a transfer to Perception or its designee (which designee may be an Affiliate or a Third Party manufacturer) of
(A) Know-How within the Otsuka Product Improvements relating to the process for the Manufacture of any Product as it exists in the Otsuka Territory as of the effective date of termination and
(B) Otsuka Termination Know-How and (ii) provide reasonable assistance to Perception in the implementation of such Know-How at a facility designated by
Perception, in each case ((i) and (ii)), excluding any such Know-How that is related to the process for the Manufacture of any Product already known by or in the control or possession of Perception or that is
related to an Other Product. 
 13.3.6 Product Trademarks. Following the expiration of this Agreement (but, for clarity, not
termination pursuant to Section 13.2), (a) Perception shall and hereby does assign to Otsuka all of its and its Affiliates’ right, title and interest in and to the Product Trademarks being used by Otsuka in the
Commercialization of Products in the Otsuka Territory as of such expiration (the “Post-Royalty Product Trademarks”) and (b) Otsuka shall be responsible, [***], for the filing, prosecution, registration and maintenance
(including the defense of opposition proceedings and any equivalent proceedings), enforcement and defense from Trademark Infringement Suits of all such Post-Royalty Product Trademarks. 

13.3.7 Return of Information and Materials. Upon termination or expiration of this Agreement, the Parties will return (or destroy, as
directed by the other Party) all data, files, records, and other materials containing or comprising the other Party’s Confidential Information. Notwithstanding the foregoing, (a) solely in the event of expiration of this Agreement pursuant
to Section 13.1 with respect to one or more Products, Otsuka will be permitted to retain Perception’s Confidential Information to the extent necessary or reasonably useful for Otsuka to exercise its rights to such
Product(s) and to exercise all license grants to Otsuka hereunder with respect to such Product(s) and (b) the Parties will be permitted to retain one copy of such data, files, records, and other materials for archival and legal compliance
purposes, and the Parties will not be required to destroy Confidential Information that is stored automatically, such as through server backup processes. 

13.3.8 Accrued Rights. Termination of this Agreement for any reason will be without prejudice to any rights or financial compensation
that will have accrued to the benefit of a Party prior to such termination. Such termination will not relieve a Party from obligations that are expressly indicated to survive the termination of this Agreement. 

  
 76 













 13.3.9 Survival. The following provisions of this Agreement will survive the
expiration or earlier termination of this Agreement: Article 1; Section 2.4; Section 2.5; Section 4.5 (solely with respect to the obligation to maintain such
records generated prior to the effective date of expiration or termination of this Agreement and such obligation shall survive for a period of [***] from the expiration or termination of this Agreement, as applicable); Sections 5.7 and
5.8.3 (in each case, solely in the event of an expiration of this Agreement and not in the event of an early termination of this Agreement); Sections 8.3-8.5, 8.7, 8.9 and
8.11 (in each case, only to the extent relating to a payment arising prior to the effective date of termination or expiration of this Agreement); Section 8.6; Section 8.8;
Section 8.10; Section 9.1 (excluding Section 9.1.4); Article 10 (excluding Section 10.2.1); Section 11.5;
Article 12; Section 13.1; Section 13.3; Section 13.4; Article 14; and Article 15. 

13.4 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by one Party to the other Party
are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code or comparable provision of applicable bankruptcy or insolvency laws in countries other than the U.S., licenses of right to “intellectual
property” as defined under Section 101 of the U.S. Bankruptcy Code or comparable provision of applicable bankruptcy or insolvency laws. The Parties agree that a Party that is a licensee of such rights under this Agreement will retain and
may fully exercise all of its rights and elections under the U.S. Bankruptcy Code or comparable provision of applicable bankruptcy or insolvency laws. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or
against a Party to this Agreement under the U.S. Bankruptcy Code or comparable provision of applicable bankruptcy or insolvency laws, the other Party will be entitled to a complete duplicate of (or complete access to, as appropriate) any such
intellectual property and all embodiments of such intellectual property, and the same, if not already in its possession, will be promptly delivered to it (a) upon any such commencement of a bankruptcy or insolvency proceeding upon its written
request therefor, unless the bankrupt Party elects to continue to perform all of its obligations under this Agreement, or (b) if not delivered under clause (a) above, following the rejection of this Agreement by or on behalf of the
bankrupt Party upon written request therefor by the other Party. 
 14. DISPUTE RESOLUTION. 

14.1 Executive Negotiation. The Parties will try to settle any dispute, controversy or claim that arises out of, or in connection
with, any provision of this Agreement, including any alleged material breach of this Agreement, but excluding any disagreement of the JCC (which is subject to Section 3.1.7 and, if applicable, Section 14.2) (“Disputed
Matter”) by first referring the Disputed Matter to the Executive Officers (the “Executive Negotiation”). Either Party may initiate the Executive Negotiation by sending written notice of the Disputed Matter to the other
Party (the “Dispute Notice” ), and, within [***] after such Dispute Notice (or such longer period as such Executive Officers or their designees may agree upon in writing), the Executive Officers (or their respective designees
having the authority to settle such Disputed Matter) of the Parties will meet (in person or by teleconference or videoconference) for attempted resolution of the Disputed Matter by good faith negotiations. Any resolution mutually agreed in writing
by the Executive Officers shall be conclusive and binding on the Parties. If the Executive Officers (or their respective designees) are unable to resolve the Disputed Matter within [***] of their first meeting for such negotiations (or such
longer period as such Executive Officers or their designees may agree upon in writing) (the “Executive Negotiation Period”), either Party may seek to have such dispute resolved in accordance with
Section 14.3. 

  
 77 













 14.2 Expert Determination. If either Party overrules the other Party’s
final decision-making authority pursuant to subsection (ii) or (iii) of Section 3.1.7(c) based on a determination that, in such Party’s reasonable judgment, a decision by the other Party
that would have a significant negative impact on the value of any Product as provided in subsection (ii) or (iii) of Section 3.1.7(c), as applicable, and if the other Party disputes such determination of a significant negative
impact, the Parties shall resolve such dispute as follows: The Parties shall agree upon a single independent expert, which expert shall have at least [***] of relevant expertise and experience in the pharmaceutical industry. If the Parties
are unable to agree upon a single expert within [***] after the conclusion of the Executive Negotiation Period (or within such longer period of time as the Parties may mutually agree in writing), then Perception and Otsuka will each select
one expert and the Parties’ two selected experts will, within [***] after selection of both Parties’ experts, jointly select a third expert who will be the sole appointed expert. If the Parties’ experts are unable to agree on
the sole expert within such [***] period, then the International Chamber of Commerce (“ICC”) International Centre for ADR shall appoint such expert in accordance with the Rules for the Appointment of Experts and Neutrals of
the ICC (the “ICC Expert Rules”). The expert shall have the discretion to request oral or written testimony from the Parties. The Parties shall cooperate fully in the expeditious conduct of the expert determination and, if the
expert requests oral testimony, the Parties shall provide the expert with a written report, including supporting documentation, in connection with such Party’s oral testimony. Within [***] after the appointment of the expert or the
conclusion of oral testimony (if applicable), each Party shall submit to the expert one proposal regarding whether a Party’s decision in the exercise of its final decision-making authority under Section 3.1.7(c), as well as a
description of whether such proposal would have a significant negative impact on the value of any Product as set forth in subsection (ii) or (iii) of Section 3.1.7(c), as applicable. The expert shall accept only one of the proposals
submitted by the Parties (without making any changes to such proposal) and shall render such proposal as the expert’s final decision. The expert’s decision shall be final and binding on the Parties. For clarity, the expert shall not have
the authority to render any decision other than selecting one of the proposals submitted by a Party, and the expert shall act as an expert and not as an arbitrator. [***]. 

14.3 Arbitration. 

14.3.1 If the Parties are unable to resolve a Disputed Matter using the process described in Section 14.1, and
if Section 14.2 does not apply (except if a Party has failed to comply with an expert’s final decision pursuant to Section 14.2, in which case such breach may be resolved pursuant to this
Section 14.3), then a Party seeking further resolution of the Disputed Matter shall submit the Disputed Matter, other than Patent Disputed Matters (which shall be resolved exclusively pursuant to
Section 14.5), to resolution by final and binding arbitration. The seat, or legal place, of arbitration shall be New York City, New York and the arbitration hearing shall take place in San Francisco, California. The
arbitration shall be administered by the ICC pursuant to its International Arbitration Rules then in effect (the “ICC Arbitration Rules”), except as otherwise provided herein. The language of the arbitration shall be English. 

  
 78 













 14.3.2 The arbitration will be conducted by a panel of three (3) arbitrators
appointed in accordance with the ICC Arbitration Rules; provided that each Party shall nominate one arbitrator and the two (2) Party-nominated arbitrators shall nominate the third arbitrator, who shall serve as the chairperson, within
[***] after the second Party-nominated arbitrator’s confirmation. Each arbitrator must have at least [***] of business or legal experience in the pharmaceutical industry. If either Party fails to nominate its arbitrator or the two
(2) Party-nominated arbitrators fail to appoint the chairperson of the arbitral tribunal within [***] after the second Party-nominated arbitrator is confirmed, either Party may apply to the ICC for the appointment of the remaining
arbitrator or the chairperson of the arbitral tribunal pursuant to ICC Arbitration Rules. The award shall be rendered within [***] after the confirmation of the chairperson of the arbitral tribunal, unless the Parties jointly request an
extension or the arbitral tribunal determines in a reasoned decision that the case requires that such limit be extended by a reasonable period. 

14.3.3 The Parties agree that any dispute concerning the propriety of the commencement of the arbitration or the scope and applicability
of the agreement to arbitrate shall be determined by the arbitrators. No arbitral tribunal will have the power to award damages excluded pursuant to Section 12.4. 

14.3.4 [***]. 

14.3.5 Except as may be required by Applicable Law, neither a Party nor any arbitrator or third party involved in the arbitration
(including fact and expert witnesses, translators, interpreters, and court reporters) may disclose the existence, content or results of any arbitration hereunder without the prior written consent of both Parties, unless to protect or pursue a legal
right. This obligation shall apply with respect to all written submissions, transcripts of hearings, procedural orders, and awards. The arbitral award shall be final and binding on the Parties and the Parties shall carry out the award without delay.
Judgment on the award so rendered may be entered in any court of competent jurisdiction. 
 14.4 Injunctive Relief.
Notwithstanding the terms of and procedures set forth in Section 14.3, any applications or motions seeking interim or conservatory measures, including temporary restraining orders, preliminary injunctions or other similar preliminary or
temporary legal or equitable relief (“Injunctive Relief”), concerning a Disputed Matter (including Disputed Matters arising out of a potential or actual breach of the confidentiality and
non-use provisions in Article 10) may be brought in the first instance for hearing and resolution in and by a court of competent jurisdiction. Alternatively, a party seeking Injunctive Relief may
immediately, without invocation or exhaustion of the procedures set forth in Section 14.3, seek Injunctive Relief in accordance with the ICC Arbitration Rules, either before an emergency arbitrator or the arbitral tribunal, and applying
the substantive law specified in law specified in Section 15.2. In either event, once the Injunctive Relief proceedings have been conducted and a decision rendered thereon by the court or emergency arbitrator or arbitral tribunal, as the
case may be, the Parties will, if the Disputed Matter is not finally resolved by the Injunctive Relief, proceed to resolve the Disputed Matter in accordance with the terms of Section 14.3.

 14.5 Non-Arbitral Disputes.
Notwithstanding Section 14.3, if a Disputed Matter pertains to the validity, scope, enforceability, infringement or ownership of any Patent Right, Trademark or copyright (a “Patent Disputed Matter”) and
such Patent Disputed Matter is not resolved in accordance with Section 14.2, such Disputed Matter shall not be submitted to arbitration pursuant to Section 14.3, unless otherwise agreed by the
Parties in writing, and instead, either Party may initiate litigation in a court of competent jurisdiction in any country in which such rights or remedies apply.
