 (g) Compulsory Licenses and Other Step-In
Rights. If Janssen, its Affiliates or any of its Sublicensees are required to grant any licenses or other rights to a Third Party (including any Governmental Authority) to Develop, Manufacture, or Commercialize a Product because of the

 (h) Combination Products. In the event that a Party
reasonably determines that any Product will be incorporated into any other product sold by Janssen or its Affiliates or Sublicensees and such Product will not be priced separately from such other product sold by Janssen or its Affiliates, such Party
shall [***] provide written notice thereof to the other Party. Upon receipt of such notice, the Parties shall [***] enter into good faith discussions to determine the reasonable Net Sales value with respect to such Product, which shall be [***].

  

	10.10.	 Third Party Obligations. 

(a) Existing Third Party Obligations. [***] shall remain responsible for the payment of royalty, milestone, and other payment
obligations, if any, due to Third Parties in connection with any Third Party License that exists as of the Effective Date and under which MeiraGTx Technology or MeiraGTx Research Technology has been licensed to MeiraGTx and is sublicensed to Janssen
under Section 4.1 for Clinical IRD Products and Janssen Research IRD Products (the “Existing Third Party Obligations”). All such payments in respect of the Existing Third Party Obligations shall be made [***] in accordance with
the terms of its agreements with the applicable Third Party License. 
 (b) Future Third Party Obligations. If either Party reasonably
determines that licensing Future Third Party Obligations would be necessary or useful to Develop, Manufacture, or Commercialize any Product in the Field in the Territory under this Agreement, then MeiraGTx shall have the first right to negotiate and
acquire (subject to Janssen’s approval; and, for clarity, if MeiraGTx declines to exercise its first right to negotiate and acquire such Future Third Party Obligations or otherwise fails to do so within [***] of any request therefor by Janssen,
Janssen shall have the right to do so) a Third Party License to such Future Third Party Obligations. If either Party negotiates and acquires a Third Party License to such Future Third Party Obligations, then: (i) [***]; (ii) [***]; provided,
however, that Janssen shall have the right to [***] for such Product [***] percent ([***]%) of the [***] paid to such Third Party under such Third Party License, and to the extent that Janssen cannot [***] paid to such Third Party exceed any
[***] owed to MeiraGTx for such Product at the time of payment to such Third Party, then Janssen may [***] payable for such Product; and (iii) Janssen thereafter shall have the right to [***] up to [***] percent ([***]%) of the [***] subject to
the following conditions: (A) Janssen may [***] and [***]; (B) such [***]; (C) if any such Third Party License either: (1) includes additional Intellectual Property Rights other than Intellectual Property Rights that are Controlled by a
Third Party and that are necessary or useful to Develop, Manufacture, or Commercialize any Product in the Field in the Territory; or (2) Covers products other than such Product, then any such [***] would be equitably allocated by Janssen in
good faith among all products and programs to which such Third Party License applies; and (D) to the extent that Janssen cannot [***], then Janssen may [***].

 (c) Breaches, Amendments and Terminations. Neither MeiraGTx nor
its Affiliates will breach or default under any Existing Third Party Obligation or any Third Party License for a Future Third Party Obligation. Neither MeiraGTx nor its Affiliates will terminate any such Third Party License in a manner that would
terminate any rights that are licensed to Janssen hereunder or otherwise diminish the scope or exclusivity of such Intellectual Property Rights licensed to Janssen hereunder. In the event that MeiraGTx or one of its Affiliates receives notice of a
potential dispute in connection with or an alleged breach by MeiraGTx or one of its Affiliates under any such Third Party License, where termination of such Third Party License or any diminishment of the scope or exclusivity of such Intellectual
Property Rights licensed to Janssen hereunder is or could be sought by the counterparty, then MeiraGTx will [***], but in no event less than [***] thereafter, provide written notice thereof to Janssen and grant Janssen the right (but not the
obligation) to cure such alleged breach, to the extent not prohibited by such Third Party License. In the event that MeiraGTx receives a notice of termination of such a Third Party License by a counterparty, MeiraGTx will [***], but in any event
within [***] following receipt of such notice, notify Janssen of such termination in writing. In the event that MeiraGTx or one of its Affiliates intends to materially amend such a Third Party License, then MeiraGTx will [***], but in no event less
than [***] before, provide written notice thereof to Janssen. Janssen will have the right (but not the obligation), acting reasonably, to reject any amendment that would increase Janssen’s obligations under this Agreement (including any
financial obligations) or diminish the licenses or rights granted to Janssen under this Agreement and in the event of any such rejection, neither MeiraGTx nor its Affiliates will enter into any such amendment unless and until Janssen approves such
amendment. 
  

	10.11.	 Reports and Royalty Payments. 

For as long as Royalties are due under Section 10.8, Janssen shall furnish to MeiraGTx a draft Sales & Royalty Report, within [***] after the end
of each Calendar Quarter, showing the estimated amount of Annual Net Sales of Products and Royalties due for such Calendar Quarter. Janssen shall furnish to MeiraGTx a final Sales & Royalty Report and pay such Royalties contained in such
final Sales & Royalty Report within [***] following the end of the applicable Calendar Quarter. 
  

	10.12.	 Disclaimer. 

MeiraGTx expressly acknowledges and agrees that, despite the efforts and obligations required by this Agreement which may result in the achievement of a
Development Milestone Event, Commercial Milestone Event or Net Sales of Product, such event or Net Sales of Product may not be achieved and MeiraGTx, in that case, would not be entitled to receive such further payments hereunder (the Development
Milestone Payment, Commercial Milestone Payment or Royalties, as the case may be), other than (i) the Upfront Payment, (ii) Research Costs to be paid as set forth in Section 10.2, (iii) Clinical Development Costs to be paid as set
forth in Section 10.3, (iv) Clinical Development Manufacturing Costs to be paid as set forth in Section 10.4, (v) Process Development Costs to be paid as set forth in Section 10.5, (vi) any Option Fee (if and when the respective
Option is exercised as set forth in Section 3.9(b)), (vii) such portion of the proceeds of Priority Review Vouchers to be paid to MeiraGTx as set forth in Section 7.1(d) and (viii) such other costs to be paid by Janssen for
Manufacturing of Products as set forth in Section 8.1(d). Any Development Milestone Payment, Commercial Milestone Payment or Royalties are contingent upon satisfaction of the conditions provided for herein which may not be satisfied. Except as
otherwise expressly provided herein (but without waiving the implied covenant of good faith and fair dealing), Janssen will be under no obligation to use its Commercially Reasonable Efforts, best efforts or any other standard of diligence with
respect to satisfying the conditions to any payment hereunder.

	10.13.	 Payment Terms. 

(a) Manner of Payment. All payments to be made by a Party hereunder will be made in Dollars by wire transfer to such bank account

For the avoidance of doubt, no payment obligations shall be incurred by either Party under or in connection with this Agreement unless and until the Effective Date. 

(b) Currency Exchange. With respect to Annual Net Sales invoiced in Dollars, the Annual Net Sales and the amounts due to MeiraGTx
under this Agreement shall be expressed in Dollars. When the conversion of payments from any foreign currency is required to be undertaken by Janssen, the Dollar equivalent shall be calculated using Janssen’s then-current standard exchange rate
methodology as applied in its external reporting for the conversion of foreign currency sales into Dollars. 
 (c) Invoices. All
invoices hereunder to be paid by a Party must reference a valid purchase order (“PO”) number which the other Party shall provide to such Party within [***] after the Effective Date and invoices shall include the nature and amount of
services rendered or deliverables provided and such other terms and conditions specified herein. Invoices to Janssen must be sent to the Johnson & Johnson Accounts Payable Department via [***] if MeiraGTx establishes a web invoice account
or sent by postal mail to the address indicated on the PO. Invoices to MeiraGTx must be sent to [***], with a cc to [***]. The other Party reserves the right to return to such Party unprocessed and unpaid those invoices that do not reference the
applicable PO number. For clarity, no invoices shall be required with respect to any Royalties due under Section 10.8. 
 (d)
Withholding Taxes. Either Party (the “Withholding Party”) may withhold from payments due to the other Party (the “Non-Withholding Party”) amounts for payment
of any withholding tax that is required by Applicable Law to be paid to any taxing authority with respect to such payments, which shall be remitted in accordance with Applicable Law. Any such tax required to be withheld will be an expense of and
borne by the Non-Withholding Party. If any such tax is assessed against and paid by the Withholding Party, then the Non-Withholding Party will indemnify and hold
harmless the Withholding Party from and against such tax, including interest. The Withholding Party shall provide to the Non-Withholding Party all relevant documentation and correspondence, and shall also
provide to the Non-Withholding Party any other cooperation or assistance on a reasonable basis as may be necessary to enable the Non-Withholding Party to claim exemption
from such withholding taxes and to receive a refund of such withholding tax or claim a foreign tax credit. The Withholding Party shall give proper evidence from time to time as to the payment of any such tax. The Parties shall cooperate with each
other in seeking deductions under any double taxation or other similar treaty or agreement from time to time in force. Such cooperation may include the Withholding Party making payments from a single source, where possible.

Development Manufacturing Costs, Process Development Costs, Manufacturing Costs, Net Sales, and such other information contained in Sales & Royalty Reports. Each Party shall keep such books and records for at least [***] following the
Calendar Year to which they pertain. 
 (b) Audits. Each Party (the “Auditing Party”) may, upon written request,
cause an internationally-recognized independent accounting firm (the “Auditor”), which is reasonably acceptable to the other Party (the “Audited Party”), to inspect the relevant records of such Audited Party and its
Affiliates to verify the payments made and amounts reported by the Audited Party and the related reports, statements, and books of accounts, as applicable. Such audit shall be limited to a period of time no more than [***] immediately preceding the

by the Audited Party with the terms of this Agreement in which case the audit may be repeated within [***] to confirm compliance. The Auditing Party agrees to hold in confidence all information received and learned in the course of any audit in
accordance with Article 12. The Auditor shall provide a draft audit report and basis for any determination to the Audited Party prior to distributing the final report so that the Audited Party can provide comment on the draft report. The final audit

 (g) Recordation. To the extent permitted by Applicable Law, if
MeiraGTx is responsible for prosecuting any Clinical IRD Patent, CMC Development Patent, Research IRD Patent or Janssen Research IRD Patent, as applicable, under this Section 11.4, then (i) [***] following the Effective Date, MeiraGTx shall
record with each Governmental Authority (where such right is available with such Governmental Authority and such Governmental Authority permits the filing of a form of short notice of license) the licenses granted in Section 4.1 against each
such Clinical IRD Patent, CMC Development Patent, Research IRD Patent or Janssen Research IRD Patent then issued by or filed with such Governmental Authority and being prosecuted by MeiraGTx, as applicable, and (ii) thereafter on a reasonably
regular basis as determined by the JSC or upon Janssen’s reasonable written request, MeiraGTx shall record with each Governmental Authority (where such right is available with such Governmental Authority and such Governmental Authority permits
the filing of a form of short notice of license) the licenses granted in Section 4.1 against each Clinical IRD Patent, CMC Development Patent, Research IRD Patent or Janssen Research IRD Patent newly filed with such Governmental Authority and
being prosecuted by MeiraGTx, as applicable, in each case ((i)-(ii)) by using a form of short notice of license mutually agreed to by the Parties (but shall not, for the avoidance of doubt, file or publicly disclose this Agreement itself for such
purposes). To the extent permitted by Applicable Law, if Janssen is responsible for prosecuting any Clinical IRD Patent, CMC Development Patent, Research IRD Patent or Janssen Research IRD Patent, as applicable, under this Section 11.4, then

 (b) Enforcement Rights for MeiraGTx
Know-How, CMC Development Technology and Clinical IRD Patents. 
 (i)
Janssen’s First Right of Enforcement. Janssen shall have the first right, but not the obligation, in the case of the MeiraGTx Know-How, CMC Development Technology or Clinical
IRD Patents to bring and control an appropriate suit or other action or defend against any Third Party Infringement or Licensed Patent Action with respect to any MeiraGTx Know-How, CMC Development Technology
or Clinical IRD Patents. MeiraGTx shall provide reasonable assistance to Janssen in such enforcement or defense, at Janssen’s request and expense, including joining such action as a party plaintiff to ensure legal standing if required by
Applicable Laws to pursue such action or if requested by Janssen. Janssen shall consult with MeiraGTx and keep MeiraGTx reasonably informed of the status of the enforcement or defense of such MeiraGTx
Know-How, CMC Development Technology or Clinical IRD Patents. Janssen shall consider MeiraGTx’s comments with respect to the enforcement or defense of such MeiraGTx
Know-How, CMC Development Technology or Clinical IRD Patents, as applicable, in good faith. Prior to settling any such suit or action, Janssen shall notify MeiraGTx in writing as to the terms of such proposed
settlement to the extent relating to MeiraGTx Know-How, CMC Development Technology or Clinical IRD Patents and shall not execute such settlement without MeiraGTx’s written consent if MeiraGTx identifies
to Janssen in reasonable detail a material risk of a material negative impact on the MeiraGTx Know-How, CMC Development Technology or Clinical IRD Patents, taking into account the potential impact on the value
of the Products worldwide as a result of such settlement. If Janssen recovers monetary damages in such claim, suit or action with respect to the MeiraGTx Know-How, CMC Development Technology or Clinical IRD
Patents, after Janssen recoups its costs and expenses associated with such litigation, with respect to any portion of such recovery remaining, [***]. 

(ii) MeiraGTx’s Back-Up Right of Enforcement. If Janssen does not, within the earlier of
[***] after learning about a Third Party Infringement or Licensed Patent Action or [***] before the expiration date for filing an appropriate suit or responding to or taking any action (as applicable), initiate and prosecute any legal action to
enforce or defend the MeiraGTx Know-How, CMC Development Technology or Clinical IRD Patents, as applicable, then MeiraGTx shall have the right, but not the obligation, to commence such a suit or take such an
action to enforce or defend the applicable MeiraGTx Know-How, CMC Development Technology or Clinical IRD Patents, as applicable. In such event, Janssen shall take appropriate actions in order to enable
MeiraGTx to commence a suit or take the actions set forth in the preceding sentence. Prior to settling any such suit or action, MeiraGTx shall notify Janssen in writing as to the terms of such proposed settlement and shall not execute such
settlement without Janssen’s written consent if Janssen identifies to MeiraGTx in reasonable detail a material risk of a material negative impact on the MeiraGTx Know-How, CMC Development Technology or
Clinical IRD Patents, taking into account the potential impact on the value of the Products worldwide as a result of such settlement. Prior to MeiraGTx commencing such a suit or action, MeiraGTx shall consider in good faith any reasonable Janssen
business concerns. If Janssen identifies to MeiraGTx in reasonable detail a material risk of a material negative impact on the MeiraGTx Know-How, CMC Development Technology or Clinical IRD Patents
resulting directly from such a suit or action, taking into account the potential impact on the value of the Products worldwide, then MeiraGTx

 shall not commence any such suit or action. If MeiraGTx recovers monetary damages in
such claim, suit or action with respect to the MeiraGTx Know-How, CMC Development Technology or Clinical IRD Patents, any portion of such recovery remaining after MeiraGTx recoups its costs and expenses
associated with such litigation, shall be [***]. 
 (c) Enforcement Rights for MeiraGTx Research
Know-How and Research IRD Patents. 
 (i) Parties’ First Right of Enforcement. Prior
to Janssen’s exercise of the applicable Option, MeiraGTx shall have the sole right to bring and control an appropriate suit or other action against any Third Party Infringement or Licensed Patent Action with respect to the MeiraGTx Research Know-How or Research IRD Patents; provided, however, that in the event that any such Third Party Infringement or Licensed Patent Action also affects MeiraGTx
Know-How, CMC Development Technology or Clinical IRD Patents, Janssen shall have the first right, but not the obligation, to bring and control such suit or other action pursuant to Section 11.5(b)(i). On
or after Janssen’s exercise of the applicable Option, Janssen shall have the first right, but not the obligation, in the case of the applicable MeiraGTx Research Know-How and Research IRD Patents to bring
and control an appropriate suit or other action against any Third Party Infringement or Licensed Patent Action with respect to such MeiraGTx Research Know-How or Research IRD Patents. MeiraGTx shall provide
reasonable assistance to Janssen in such enforcement or defense, at Janssen’s request and expense, including joining such action as a party plaintiff to ensure legal standing if required by Applicable Laws to pursue such action or if requested
by Janssen. Janssen shall consult with MeiraGTx and keep MeiraGTx reasonably informed of the status of the enforcement or defense of such MeiraGTx Research Know-How and Research IRD Patents. Janssen shall
consider MeiraGTx’s comments with respect to the enforcement or defense of such MeiraGTx Research Know-How or Research IRD Patents in good faith. Prior to settling any such suit or action, Janssen shall
notify MeiraGTx in writing as to the terms of such proposed settlement to the extent relating to MeiraGTx Research Know-How and Research IRD Patents and shall not execute such settlement without
MeiraGTx’s written consent if MeiraGTx identifies to Janssen in reasonable detail a material risk of a material negative impact on the MeiraGTx Research Know-How or Research IRD Patents, taking into
account the potential impact on the value of the Products worldwide as a result of such settlement. If Janssen recovers monetary damages in such claim, suit or action with respect to the MeiraGTx Research
Know-How or Research IRD Patents, after Janssen recoups its costs and expenses associated with such litigation, with respect to any portion of such recovery remaining, [***]. 

(ii) MeiraGTx’s Back-Up Right of Enforcement. If Janssen does not, within [***] after
learning about a Third Party Infringement or Licensed Patent Action or [***] before the expiration date for filing an appropriate suit or responding to or taking any action (as applicable), initiate and prosecute any legal action to enforce or
defend the MeiraGTx Research Know-How or Research IRD Patents, as applicable, then MeiraGTx shall have the right, but not the obligation, to commence such a suit or take such an action to enforce the
applicable MeiraGTx Research Know-How or Research IRD Patents. In such event, Janssen shall take appropriate actions in order to enable MeiraGTx to commence a suit or take the actions set forth in the
preceding sentence. Prior to settling any such suit or action, MeiraGTx shall notify Janssen in

 writing as to the terms of such proposed settlement and shall not execute such
settlement without Janssen’s written consent if Janssen identifies to MeiraGTx in reasonable detail a material risk of a material negative impact on the MeiraGTx Research Know-How or Research IRD Patents,
taking into account the potential impact on the value of the Products worldwide as a result of such settlement. Prior to MeiraGTx commencing such a suit or action, MeiraGTx shall consider in good faith any reasonable Janssen business
concerns. If Janssen identifies to MeiraGTx in reasonable detail a material risk or a material negative impact on the MeiraGTx Research Know-How or Research IRD Patents resulting directly from such a suit
or action, taking into account the potential impact on the value of the Research IRD Products worldwide, then MeiraGTx shall not commence any such suit or action. If MeiraGTx recovers monetary damages in such claim, suit or action with respect to
the MeiraGTx Research Know-How or Research IRD Patents, any portion of such recovery remaining after MeiraGTx recoups its costs and expenses associated with such litigation shall be [***]. 

(d) Cooperation. At the request of the Party bringing and controlling any Third Party Infringement or defending any Licensed Patent
Action, as applicable (“Controlling Party”), the other Party shall provide reasonable assistance in connection with such action, including by executing reasonably appropriate documents, providing access to such
Party’s premises and employees, cooperating reasonably in discovery, and joining as a party to the action if requested by the Controlling Party. The Controlling Party will keep the other Party reasonably informed of all material developments in
connection with any such suit, and the other Party shall have the right to consult with the Controlling Party and to participate in and, if appropriate, be represented by independent but mutually agreed upon counsel in such litigation at such other
Party’s own cost and expense. 
  

	11.6.	 Product Infringement. 

If a Party becomes aware of any actual or potential Claim alleging that the Research, Development, Manufacture, or Commercialization of any Products under this
Agreement infringes, misappropriates, or otherwise violates any Intellectual Property Rights of a Third Party (or would if carried out) (“Product Infringement”), then such Party will notify the other Party [***] following the
receipt of service of process in such action, suit, or proceeding, or the date on which such Party becomes aware that such action, suit, or proceeding has been instituted, and the Parties will meet as soon as possible to discuss the overall strategy
for defense of such matter. Janssen shall have the first right (but not the obligation) to defend any Claims of Product Infringement. If Janssen does not intend to defend such Product Infringement or determines to cease defending any such
Product Infringement and informs MeiraGTx that it wishes for MeiraGTx to defend such Product Infringement, then MeiraGTx will have the right, but not the obligation, upon written notice to Janssen, to defend such Product Infringement or take over
defense of the Product Infringement from Janssen, as applicable. Notwithstanding anything to the contrary, if either Party has an obligation to indemnify the other Party with respect to such Claim of Product Infringement, then the provisions of
Article 17 will apply with respect thereto.

[***] after the expiration or earlier termination of this Agreement, subject to the other provisions of this Article 12, each Party will, as a receiving Party (the “Receiving Party”), and will cause its Affiliates to, maintain in
confidence, not publish or otherwise disclose and otherwise safeguard, any and all Confidential Information disclosed by or on behalf of the other Party (the “Disclosing Party”) or its Affiliates under this Agreement to it, using

Affiliates under this Agreement. 
 Specific aspects or details of Confidential Information shall not be deemed to be within the public
domain or in the possession of the Receiving Party merely because the Confidential Information is embraced by more general information in the public domain or in the possession of the Receiving Party. Further, any combination of Confidential
Information shall not be considered in the public domain or in the possession of the Receiving Party merely because individual elements of such Confidential Information are in the public domain or in the possession of the Receiving Party, unless the
combination and its principles are in the public domain or in the possession of the Receiving Party.

restrictive than those contained in this Article 12; (vii) as permitted in accordance with Article 13; or (viii) as mutually agreed to in writing by the Parties. 

(b) Disclosures pursuant to Applicable Law. If the Receiving Party is required to disclose Confidential Information of the Disclosing
Party pursuant to Applicable Law (including the rules of the Securities and Exchange Commission or any stock exchange) or in connection with any bona fide legal process, including disclosures of the type contemplated by Section 12.3(a), such
disclosure to the extent reasonably necessary shall not be deemed a breach of this Agreement; provided, however, that the Receiving Party, except where reasonably impracticable or legally impermissible, will: (i) inform the
Disclosing Party as soon as reasonably practicable following it becoming aware of the required disclosure; (ii) limit the disclosure to the required purpose; and (iii) at the Disclosing Party’s request and reasonable expense, assist

Party, then at the non-submitting Party’s election, (i) the submitting Party will delay submission of its publication, abstract or presentation for an additional period, not to exceed [***] or such
other period mutually agreed to by the Parties, in order to allow for the filing of a Patent or other appropriate Intellectual Property Rights protection for such material or (ii) the submitting Party will remove the identified material prior

content of such required disclosure. If so requested by the other Party, except where impracticable or not legally permitted, the Party subject to such obligation shall use commercially reasonable efforts to obtain an order protecting the
confidentiality of such provisions of this Agreement, as determined by the Disclosing Party in consultation with its legal counsel. Without limiting the foregoing, MeiraGTx shall use commercially reasonable efforts to provide Janssen with each

	14.2.	 Filings. 

The Parties shall cooperate with one another in the preparation and execution of all documents that are required to be filed pursuant to the HSR Act. Each
Party shall, within [***] following the Execution Date (or such later time as may be agreed to in writing by the Parties), file with the United States Federal Trade Commission and the Antitrust Division of the United States Department of Justice,
and/or with equivalent foreign authorities, any HSR Filing required of it in the reasonable opinion of either Party with respect to the transactions contemplated hereby. Neither Party shall seek expedited treatment of any HSR Filing without the

under the HSR Act. The Parties shall cooperate with one another to the extent necessary in the preparation of any such HSR Filing. Each Party shall be responsible for its own costs, expenses, and filing fees associated with any HSR Filing;
provided, however, that Janssen shall be solely responsible for any fees (other than penalties that may be incurred as a result of actions or omissions on the part of MeiraGTx) required to be paid to any Governmental Authority in
connection with making any such HSR Filing.

	15.	 TERM AND TERMINATION 

 

	15.1.	 Term. 

The term of this Agreement shall commence upon the Effective Date and, unless terminated pursuant to Section 15.2, shall continue in full force and
effect, on a Product-by-Product and country-by-country basis, until such time as the
Royalty Term expires in such country (the “Term”). On a Product-by-Product and
country-by-country basis, effective upon the expiration of the Royalty Term for such Product in such country (but not for any termination of this Agreement), the
licenses granted to Janssen will each become fully paid-up, royalty-free, irrevocable, and perpetual in such country with respect to such Product. 

 

	15.2.	 Termination. 

This Agreement may be terminated as follows: 
 (a)
Termination for Breach. 
 (i) General. Subject to Section 15.2(a)(ii), if either Janssen or MeiraGTx is in material
breach of this Agreement, the non-breaching Party must give written notice to the breaching Party within [***] following the alleged breach specifying the claimed particulars of such breach in sufficient
detail to put the allegedly breaching party on reasonable notice of the nature of the alleged breach, and in the event such material breach is not cured within [***] after such notice (or in the case of any undisputed payment obligations, [***]
after such notice), the non-breaching Party shall have the right thereafter to terminate this Agreement immediately, in whole or with respect to the applicable Product (except with respect to a material breach
by Janssen arising under Section 6.1(e), Section 6.2(a), Section 8.4(a), Article 9 and Section 19.4, which must be terminated on a Product-by-Product
basis), by giving written notice to the breaching Party to such effect; provided, however, that if such breach is capable of being cured but cannot be cured within the period referenced above and the breaching Party initiates actions
to cure such breach within such period and thereafter diligently pursues such actions, the breaching Party shall have such additional period as is reasonable under the circumstances to cure such breach; it being understood that no such extension
shall apply with respect to any undisputed payment obligations. If arbitration is commenced with respect to any alleged breach hereunder pursuant to Section 18.1, no purported termination of this Agreement pursuant to this
Section 15.2(a)(i) shall take effect until: (A) a final resolution of such arbitration; and (B) the losing Party in such arbitration fails to satisfy the arbitration award within the cure time frames referenced above. 

(ii) Janssen Special Remedy. If Janssen would have the right to terminate this Agreement under Section 15.2(a)(i), in whole
or in part, for an uncured material breach by MeiraGTx in connection with a Product, then Janssen may, in its sole discretion, elect: (A) to either exercise such termination right or (B) in lieu of exercising such termination right, and
without limiting Janssen’s rights otherwise set under this Agreement, subsequently reduce any payment amounts due to MeiraGTx under [***] for such Product by [***] percent ([***]%) as a result of this Section 15.2(a)(ii).

 (b) Termination for Insolvency. This Agreement may be immediately
terminated in its entirety by a Party by providing written notice of termination to the other Party in the event of an Insolvency Event of the other Party. 

(c) Termination for Patent Challenge. To the extent permitted by Applicable Law, if Janssen or any of its Affiliates Challenges any
Patent included in the MeiraGTx Patents, MeiraGTx Research Patents or Joint Patents in any country in the Territory (such Patent, a “Challenged Patent”), then MeiraGTx may, following written notice to Janssen and provided
that Janssen or its Affiliate does not withdraw such Challenge within [***] after receipt of such notice, terminate this Agreement in its entirety by providing written notice of termination to Janssen; provided that this
Section 15.2(c) will not apply to, and MeiraGTx may not terminate this Agreement with respect to (i) any claim or proceeding that would otherwise be a Challenge hereunder to the extent commenced by a Third Party that after the Effective
Date acquires or is acquired by Janssen or its Affiliates or its or their business or assets, whether by stock purchase, merger, asset purchase, or otherwise; provided that such proceeding commenced prior to the closing of such acquisition;
(ii) any claim or proceeding by a licensor of a product licensed by Janssen for which the licensor has an existing challenge, whether in a court or administrative proceeding, against any MeiraGTx Patent, MeiraGTx Research Patent or Joint
Patent; (iii) any Challenge required to be commenced pursuant to an order of a Governmental Authority or Applicable Law; (iv) any Challenge that is commenced by a Sublicensee; provided that Janssen demands that such Sublicensee
withdraw such Challenge [***] after Janssen becomes aware of such Challenge and terminates the sublicense agreement with the applicable Sublicensee if such Sublicensee does not withdraw such Challenge within [***] after receipt of such demand from
Janssen; (v) any proceeding not initiated, directed or controlled by or on behalf of Janssen or one of its Affiliates, for which Janssen or the Affiliate, as the case may be, opposes, or assists any Third Party to oppose, the grant of a
MeiraGTx Patent, MeiraGTx Research Patent or Joint Patent pursuant to any application in relation thereto in an administrative proceeding, such as a patent re-examination, inter partes review, or other
post grant proceeding or opposition; (vi) challenges by an open forum entity or other industry group in which Janssen or its Affiliates or Sublicensees do not direct or control the action of such entity; (vii) general activities not
specifically directed to a particular Patent, such as amicus briefs on cases not involving any MeiraGTx Patent, MeiraGTx Research Patent or Joint Patent; (viii) lobbying or other efforts directed to patent issues generally and not to any
specific Patent; (ix) any affirmative defense or other validity, enforceability, or non-infringement challenge, whether in the same action or in any other agency or forum of competent jurisdiction,
advanced by Janssen, any of its Affiliates or Sublicensees in response to any claim or action brought in the first instance by, or on behalf of, MeiraGTx or any Third Party; (x) providing documents or testimony in response to any discovery
requests or court order in a valid legal process not directed to Challenging any Challenged Patent; or (xi) any Challenge related to any Clinical IRD Patent, CMC Development Patent, Research IRD Patent or Janssen Research IRD Patent for which
Janssen’s reasonable input with respect to such Patent’s prosecution, maintenance or enforcement pursuant to Section 11.4 or Section 11.5 was not included in any filings or correspondence with patent authorities or otherwise
accepted or pursued by MeiraGTx (as applicable). 
 (d) Termination by Janssen At Will. Beginning on [***], Janssen may terminate this
Agreement at will in its entirety or on a Product-by-Product basis at any time on: (i) [***] prior written notice to MeiraGTx, if prior to the First Commercial Sale
of such Product; and (ii) on [***] prior written notice to MeiraGTx, if following the First Commercial Sale of such Product.

	15.3.	 Rights in Insolvency. 

The Parties agree that this Agreement constitutes an executory contract under Section 365 of the Code for the license of “intellectual property”
as defined under Section 101 of the Code and constitutes a license of “intellectual property” for purposes of any similar laws in any other country in the Territory. The Parties further agree that Janssen, as licensee of such rights
under this Agreement, will retain and may fully exercise all of its protections, rights and elections under the Code, including under Section 365(n) of the Code, and any similar laws in any other country in the Territory and that Janssen cannot
be compelled to accept a money satisfaction of its interests in the intellectual property licensed pursuant to this Agreement, and that any such sale therefore may not be made to a purchaser “free and clear” of Janssen’s rights under
this Agreement and Section 365(n) without the express, contemporaneous consent of Janssen. The Parties further agree that, in the event of an Insolvency Event by or against MeiraGTx under the Code and any similar laws in any other country in
the Territory, Janssen may be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property (including Materials and Research Results), and the same, if
not already in its possession, will be [***] delivered to it: (a) upon any such commencement of an Insolvency Event upon its written request therefor, unless MeiraGTx 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 MeiraGTx upon written request therefor by Janssen. Whenever MeiraGTx or any of its successors or assigns provides to Janssen any of
the intellectual property licensed hereunder (or any embodiment thereof including Materials and Research Results) pursuant to this Section 15.3, Janssen shall have the right to perform MeiraGTx’s obligations hereunder with respect to such
intellectual property, but neither such provision nor such performance by Janssen shall release MeiraGTx from liability resulting from rejection of the license or the failure to perform such obligations. MeiraGTx and Janssen each acknowledges and
agrees that Option Fees, Development Milestone Payments, Commercial Milestone Payments and Royalties constitute royalties within the meaning of Section 365(n) of the Bankruptcy Code. 

All rights, powers and remedies of Janssen provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or
hereafter existing at law or in equity (including the Bankruptcy Code) in the event of the commencement of a case under the Bankruptcy Code with respect to MeiraGTx. The Parties agree that they intend the following rights to extend to the maximum
extent permitted by law, and to be enforceable under Bankruptcy Code Section 365(n): 
 (i) the right of access to any intellectual
property rights (including all embodiments thereof) of MeiraGTx licensed to Janssen hereunder, or any Third Party with whom MeiraGTx contracts to perform an obligation of MeiraGTx under this Agreement, and, in the case of the Third Party, which is
necessary for the Manufacture, use, sale, import or export of Products; and

 (ii) the right to contract directly with any Third Party to complete the
contracted work. 
  

	15.4.	 Effects of Expiration or Termination. 

(a) Licenses. Upon any expiration or termination of this Agreement after the Effective Date, in whole or in part, any licenses granted
by a Party under Section 4.1 with respect to a Terminated Product will terminate, except to the extent necessary for Janssen to perform any of its obligations that survive such termination, to conduct wind-down activities in compliance with
applicable legal and ethical obligations, or to the extent set forth in Section 4.1(c) or Section 15.1, and each of the Parties’ respective obligations with respect to such Terminated Product shall terminate, except as set forth in
Section 15.1, Section 15.4, Section 15.5 and Section 15.6. For clarity, upon any termination in part of this Agreement, the licenses granted under Article 4 shall survive with respect to the Products not affected by such partial
termination. 
 (b) Confidential Information. Upon any expiration or termination of this Agreement, in whole or in part, each Party
will destroy all written, electronic, or other materials containing Confidential Information of the other Party, including all copies thereof relating to such Terminated Product within [***] of such termination and provide certification of such
destruction to the owning Party; provided, that: (i) a Party may retain one (1) copy of any materials containing Confidential Information of the other Party in its archives solely for the purpose of monitoring its ongoing
confidentiality obligations hereunder; and (ii) a Party will not be obligated to destroy such materials containing Confidential Information of the other Party that are necessary for the Party to exercise any other license or right of such Party
that survives such termination of this Agreement; provided, however, that the receiving Party’s use of such Confidential Information will continue to be subject to the requirements and restrictions set forth in Article 12. 

(c) Wind-Down Activities. Upon any termination of this Agreement, in whole or in part, by MeiraGTx for Janssen’s uncured material
breach under Section 15.2(a), by MeiraGTx under Section 15.2(b) or Section 15.2(c), or by Janssen under Section 15.2(d), then the following shall occur: 

(i) Janssen hereby grants to MeiraGTx, with respect to the Terminated Product(s), a non-exclusive,
perpetual and irrevocable right and license, with the right to grant sublicenses (through multiple tiers), under Janssen’s Sole Inventions as necessary to Develop, Manufacture and Commercialize such Terminated Product(s) in the Field in the
Territory; 
 (ii) Effective as of such termination date, Janssen hereby assigns, and shall [***] transfer (at MeiraGTx’s reasonable
expense, unless MeiraGTx terminated this Agreement, in whole or in part, for Janssen’s uncured material breach under Section 15.2(a), in which case such transfer shall be at Janssen’s reasonable expense) on an as-is, where-is basis, to MeiraGTx or MeiraGTx’s designee possession and ownership of all governmental or regulatory correspondence, conversation logs, filings and
approvals (including all Regulatory Approvals and Pricing Approvals), and global safety database, in each case relating to the Development, Manufacture or Commercialization of the Terminated Product(s) and to the extent permitted under Applicable
Law, and Janssen shall reasonably cooperate, at no additional out-of-pocket cost to Janssen, with requests by MeiraGTx for assistance necessary to facilitate
MeiraGTx’s assumption of regulatory responsibilities for the Terminated Product(s) in the applicable countries in which direct transfer is not permitted during the [***] following such termination date;

 (iii) Effective as of such termination date, Janssen hereby assigns (and
shall ensure that its Affiliates or Sublicensees hereby assign) to MeiraGTx all Trademarks used solely with respect to the Terminated Product(s) in the Territory (together with the goodwill associated with the foregoing); and 

(iv) Effective as of such termination date, Janssen shall [***] provide MeiraGTx with a summary of all Third Party agreements relating to the
Development, Manufacture or Commercialization of the Terminated Product(s) to which Janssen is a party (other than those to be assigned to MeiraGTx) and shall assign to MeiraGTx any Third Party agreements solely relating to the Development,
Manufacture or Commercialization of the Terminated Product(s), and MeiraGTx shall accept such assignment, including responsibility for all liabilities and obligations accruing under such agreements from and after the date of termination, in each
case to the extent permitted thereunder. With respect to each agreement relating to the Development, Manufacture or Commercialization of Terminated Product(s) that is not transferred to MeiraGTx, at MeiraGTx’s request, Janssen shall use
reasonable efforts to facilitate a direct introduction between MeiraGTx and the Third Party counterparty to such agreement. 
 (d)
Clinical Studies. If Janssen is conducting any Clinical Study on the date of notice of termination for any reason under this Agreement, then MeiraGTx shall notify Janssen within [***] after the notice of termination with regard to any
Clinical Study, whether MeiraGTx elects to have Janssen (i) complete such Clinical Study on behalf of MeiraGTx (unless Janssen reasonably believes there is a material safety issue that should prevent the continuation of such Clinical Study),
(ii) wind down such Clinical Study as soon as practicable, subject to compliance with ethical and legal requirements, or (iii) transfer such Clinical Study to MeiraGTx as soon as practicable. Notwithstanding the foregoing, if Janssen terminates
this Agreement pursuant to Section 15.2(a) or 15.2(b), then this Section 15.4(d) shall not apply and Janssen, at its sole discretion, shall determine whether to continue or wind down any ongoing Clinical Study, subject to compliance with
ethical and legal requirements; and each Party shall bear its own expenses incurred pursuant to such wind down. In addition, and subject to the foregoing: 

(i) If MeiraGTx notifies Janssen of its election to have Janssen complete a Clinical Study on behalf of MeiraGTx, Janssen and MeiraGTx will, as
necessary, negotiate in good faith a separate agreement pursuant to which Janssen would complete such Clinical Study. If the Parties fail to reach agreement within [***] after MeiraGTx makes such election, Janssen may wind down such Clinical Study,
subject to compliance with ethical and legal requirements or, if requested by MeiraGTx, transfer such Clinical Study to MeiraGTx. 
 (ii) If
MeiraGTx notifies Janssen of its election to have Janssen wind down such Clinical Study (or fails to provide notice within such [***] period), then Janssen shall wind-down such Clinical Study as soon as practicable, subject to compliance with
ethical and legal requirements.

 (iii) If MeiraGTx notifies Janssen of its election to have Janssen
transfer such Clinical Study to MeiraGTx, then Janssen shall use commercially reasonable efforts to transfer, and MeiraGTx shall use commercially reasonable efforts to assume, such Clinical Study as [***] as practicable (and, in any event, within
[***]) after the effective date of termination. 
 (iv) The costs of ongoing Clinical Studies under this Section 15.4(d) shall be borne
as follows: 
 (A) By [***] after the effective date of termination, if [***]. [***] shall reimburse [***] for any such costs incurred by
[***] after the effective date of termination. 
 (B) By [***] after the effective date of termination, if [***]. [***] shall reimburse [***]
after the effective date of termination. 
 (C) By [***] as follows after the effective date of termination, if [***]: (x) by [***] until the
earlier of (i) completion of such wind-down or (ii) [***] after the effective date of termination for such Clinical Study for such Clinical IRD Product; and (y) by [***] until the completion of such wind-down; provided that both
Parties shall cooperate to wind-down such Clinical Study for such Clinical IRD Product as soon as reasonably practicable, including through discussions with the applicable Regulatory Authorities to minimize the compliance and legal requirement
period for such wind-down. 
 (D) By [***] after the effective date of termination, if [***] until the completion of such wind-down.
 
 (e) Further Actions. Janssen shall take all such further actions within the [***] following such termination of this
Agreement, in whole or in part, as may be reasonably requested by MeiraGTx in order to give effect to the foregoing clauses in this Section 15.4, [***]. 

(f) Rights Terminated. Except as set forth in Section 15.1, Section 15.4, Section 15.5 and Section 15.6, the rights
and obligations of the Parties hereunder shall terminate as of the date of such termination of this Agreement, in whole or in part, with respect to the Terminated Product(s). For clarity, termination of this Agreement, in whole or part, will not
affect a Party’s rights to freely exploit CMC Development Inventions or CMC Development Patents in accordance with Article 11. In addition, upon any expiration or termination of this Agreement after the Effective Date, in whole or in part, each
Party shall not undertake any further actions under this Agreement following such expiration or termination except in accordance with this Section 15.4. Subject to Section 15.2(a)(ii), Section 15.4(d) and Section 15.5, in the
event of any expiration or termination of this Agreement, in whole or in part, (i) Janssen will pay all amounts then due and owing to MeiraGTx in accordance with Article 10 as of the effective date of such expiration or termination;
(ii) each Party will use reasonable efforts to mitigate and avoid any costs incurred by or on behalf of such Party on or after such date of expiration and termination, to the extent to be reimbursed by the other Party in accordance with the
express terms herewith (including under Section 15.4(d)(iv)(C)); and (iii) no further payment amounts shall be due to MeiraGTx with respect to the Terminated Product(s) after the effective date of such expiration or termination.

	15.5.	 Post-Termination Royalties to Janssen. 

Following termination of this Agreement, in whole or in part, with respect to a Product, MeiraGTx shall be obligated to pay Janssen a royalty on Net Sales of
such Product in the amount of: (a) [***] percent ([***]%) of Net Sales if a Phase 2 Study has not been initiated for such Product as of the effective date of termination; (b) [***] percent ([***]%) of Net Sales if a Phase 2 Study has been initiated
as of the effective date of termination but a Pivotal Study has not been initiated for such Product as of the effective date of termination; (c) [***] percent ([***]%) of Net Sales if a Pivotal Study has been initiated for such Product as of the
effective date of termination but Pricing Approval in at least one (1) country has not been obtained for such Product as of the effective date of termination; or (d) [***] percent ([***]%) of Net Sales if Pricing Approval in at least one
(1) country has been obtained for such Product as of the effective date of termination. The royalty reporting, payment, record-keeping, audit and withholding tax provisions set forth in Sections 10.8, 10.9, 10.11, 10.13(d) and 10.14 and
“Royalty Term” definition set forth in Section 10.9(a) shall apply mutatis mutandis to royalties payable pursuant to this Section 15.5. For purposes of this Section 15.5, “Net Sales” shall have the meaning
given to it in Section 1.176, as if the references to Janssen in such definition were to MeiraGTx. 
  

	15.6.	 Survival. 

Expiration or termination of this Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination. Subject to the
other terms and conditions regarding the termination and survival of obligations under this Agreement in the event of expiration or termination of this Agreement, upon expiration or termination of this Agreement, all provisions of this Agreement
will cease to have any effect, except that the following provisions will survive any such expiration or termination for any reason for the period of time specified therein, or if not specified, then they will survive indefinitely: Article 1

indemnify MeiraGTx Indemnitees pursuant to Section 17.2 for such Claim. 
  

	17.2.	 Indemnification by Janssen.

 (c) Janssen’s Research, Development or Commercialization activities
with respect to any Janssen Research IRD Product pursuant to Section 2.2(a), Section 6.2(a), Section 7.2(a) or Article 9; 

(d) Janssen’s Development or Commercialization activities with respect to any Clinical IRD Product, including conducting its Clinical
Development Plan Activities pursuant to Section 6.1(c) and Section 6.1(e), regulatory activities after [***] pursuant to Section 7.1(a) and Commercialization activities pursuant to Article 9; or 

(e) Janssen’s Manufacturing activities with respect to any Product, including Manufacturing Products pursuant to the applicable Supply

 except that Janssen shall not be obliged to so
indemnify the MeiraGTx Indemnitees for any Claim to the extent that MeiraGTx has an obligation to indemnify Janssen Indemnitees pursuant to Section 17.1 for such Claim. 
  

	17.3.	 Indemnification Procedure. 

(a) For the avoidance of doubt, all indemnification claims in respect of a Janssen Indemnitee or MeiraGTx Indemnitee shall be made solely by
Janssen or MeiraGTx, respectively. 
 (b) A Party seeking indemnification hereunder (the “Indemnified Party”) shall
notify the other Party (the “Indemnifying Party”) in writing reasonably [***] after the assertion against the Indemnified Party of any Claim or fact in respect of which the Indemnified Party intends to base a claim for
indemnification hereunder (an “Indemnification Claim Notice”); provided, that the failure or delay to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any obligation or liability that it may have
to the Indemnified Party, except to the extent that the Indemnifying Party demonstrates that its ability to defend or resolve such Claim is adversely affected thereby. The Indemnification Claim Notice shall contain a description of the Claim and the
nature and amount of the Claim (to the extent that the nature and amount of such Claim is known at such time). Upon the request of the Indemnifying Party, the Indemnified Party shall furnish [***] to the Indemnifying Party copies of all
correspondence, communications, and official documents (including court documents) received or sent in respect of such Claim. 
 (c)
Subject to Section 17.3(d) and Section 17.3(e), the Indemnifying Party shall have the right, upon written notice given to the Indemnified Party, to assume the defense and handling of such Claim, at the Indemnifying Party’s sole
expense, in which case Section 17.3(d) shall govern. The assumption of the defense of a Claim by the Indemnifying Party shall be construed as acknowledgement that the Indemnifying Party is liable to indemnify any Indemnitee with respect to the
Claim, and shall constitute a waiver by the Indemnifying Party of any defenses it may assert against any Indemnified Party’s claim for indemnification. Until the Indemnifying Party gives such written notice to the Indemnified Party,
Section 17.3(e) shall govern. An Indemnifying Party will not have the right to conduct the defense of any Claim (a) brought by a Governmental Authority, (b) where such Claim involves injunctive relief (which cannot reasonably be
severed from the proceeding for damages) or (c) where the Indemnified Party reasonably believes that the Indemnifying Party does not have the financial resources to discharge its indemnification obligation in full, unless the Indemnifying Party
posts a bond to cover such potential indemnification obligations.

 (d) Upon assumption of the defense of a Claim by the Indemnifying Party:
(i) the Indemnifying Party shall have the right to and shall assume sole control and responsibility for defending and handling the Claim; (ii) the Indemnifying Party may, at its own cost, appoint as counsel in connection with conducting
the defense and handling of such Claim any law firm or counsel selected by the Indemnifying Party which is reasonably acceptable to the Indemnified Party; (iii) the Indemnifying Party shall keep the Indemnified Party informed of the status of
such Claim; and (iv) the Indemnifying Party shall have the right to settle such Claim on any terms the Indemnifying Party chooses; provided, however, that it shall not, without the prior written consent of the Indemnified Party
(such consent not to be unreasonably withheld, conditioned, or delayed), agree to a settlement of any Claim which could lead to liability or create any financial or other obligation on the part of the Indemnified Party for which the Indemnified
Party is not entitled to indemnification under this Agreement or which admits any wrongdoing or responsibility for the Claim on behalf of the Indemnified Party or which involves a conduct restriction or obligation of any kind. The Indemnified Party
shall cooperate with the Indemnifying Party and shall be entitled to participate in, but not control, the defense of such Claim with its own counsel and at its own expense. In particular, the Indemnified Party shall furnish such records,
information, and testimony, provide witnesses, and attend such conferences, discovery proceedings, hearings, trials, and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business
hours by the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Claim, and making the Indemnified Party, the Indemnitees, and its and their employees and agents
available on a mutually convenient basis to provide additional information and explanation of any records or information provided. 
 (e) If
the Indemnifying Party does not assume the defense of the Indemnified Party in accordance with Section 17.3(c), the Indemnified Party may, at the Indemnifying Party’s expense, select counsel reasonably acceptable to the Indemnifying Party
in connection with conducting the defense and handling of such Claim and defend or handle such Claim in such manner as it may deem appropriate. In such event, the Indemnified Party shall keep the Indemnifying Party reasonably informed of the status
of such Claim and shall not settle such Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned, or delayed. If the Indemnified Party defends or handles such Claim, the
Indemnifying Party shall cooperate with the Indemnified Party, at the Indemnified Party’s request but at no expense to the Indemnified Party, and shall be entitled to participate in the defense and handling of such Claim with its own counsel
and at its own expense. 
 (f) Neither Party shall have the obligation to indemnify the other Party in connection with any settlement made
without the Indemnifying Party’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

	17.4.	 Mitigation of Loss. 

Each Indemnified Party will take and will procure that the other Janssen Indemnitees (where Janssen is the Indemnified Party) or the MeiraGTx Indemnitees
(where MeiraGTx is the Indemnified Party) take all such reasonable steps and actions in order to mitigate any potential Damages under this Article 17. 
  

	17.5.	 Limited Liability. 

NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR ANY SPECULATIVE OR PUNITIVE DAMAGES OF ANY KIND ARISING FROM OR RELATING TO THIS AGREEMENT, THE
NEGOTIATION OF THIS AGREEMENT OR THE ACTIVITIES CONDUCTED HEREUNDER, OR ANY OTHER DAMAGES NOT REASONABLY FORESEEABLE AS A PROXIMATE RESULT OF THE BREACH OF A PARTY OF THIS AGREEMENT, ON ANY THEORY OF LIABILITY (WHETHER IN CONTRACT, TORT, STRICT
LIABILITY OR OTHERWISE), REGARDLESS OF ANY NOTICE, AWARENESS OR ADVICE OF THE LIKELIHOOD OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 17.5 IS INTENDED TO OR SHALL LIMIT OR RESTRICT INDEMNIFICATION FOR DAMAGES OF THE
NATURE DESCRIBED ABOVE THAT ARE PAYABLE TO A THIRD PARTY FOLLOWING A FINAL ADJUDICATION OF THE MATTER IN QUESTION OR A SETTLEMENT EFFECTED IN ACCORDANCE WITH THIS AGREEMENT. 
  

	17.6.	 Insurance Obligations 

Each Party, at its own expense, shall procure and maintain during the Term and for a period of [***] thereafter product liability insurance adequate to cover
the activities to be conducted by such Party and its obligations under this Agreement that are consistent with normal business practices of prudent companies similarly situated; provided, however, that in no event shall such product
liability insurance be written in amounts less than [***] per claim or per occurrence and annual aggregate. All such insurance shall include worldwide coverage. Prior to the initiation of any Clinical Study of a Product, the Party responsible for
such Clinical Study shall secure, and maintain in full force and effect, clinical trial insurance as required by Applicable Law in those territories where such Clinical Study shall be conducted. It is understood that such insurance shall not be
construed to create a limit of either Party’s liability with respect to its indemnification obligations under Section 17.1 and Section 17.2. Each Party shall provide the other Party with written evidence of such insurance upon
request. Each Party shall provide the other Party with written notice at least [***] prior to the cancellation, non-renewal or material change of such insurance that could materially adversely affect the
rights of such other Party hereunder. Notwithstanding the foregoing, either Party’s failure to maintain adequate insurance shall not relieve that Party of its obligations set forth in this Agreement. The Parties acknowledge and agree that
Janssen may meet its obligations under this Section 17.6 through self-insurance consistent with the levels set forth herein with prior written notice to MeiraGTx. In such event, Janssen shall provide a written certification of such
self-insurance to MeiraGTx upon request.

	18.	 DISPUTE RESOLUTION 

 

	18.1.	 Dispute Resolution. 

(a) Escalation; Decision-Making Authority. In the case of any dispute, claim or controversy between the Parties arising from or related
to this Agreement, or the interpretation, application, breach, termination or validity of this Agreement and which are not subject to Section 5.8(c) (a “Dispute”), the Parties will discuss and negotiate in good faith a solution
acceptable to the Parties and in the spirit of this Agreement. If, after negotiating in good faith pursuant to the foregoing sentence, the Parties fail to reach agreement within [***] (or such longer period as agreed in writing by the Parties), then
the Dispute may be referred to the Executive Officers for resolution at the request of either Party. If, after negotiating in good faith, the Executive Officers fail to reach agreement within [***] of submission to the Executive Officers (or such
longer period as agreed in writing by the Parties), then either Party may upon written notice to the other submit the Dispute to non-binding mediation pursuant to Section 18.1(b). 

(b) Mediation. 
 (i) If the
Parties fail to resolve the Dispute pursuant to Section 18.1(a), the Parties shall attempt in good faith to resolve any Dispute by confidential mediation in accordance with the then-current Mediation Procedure of the International Institute for
Conflict Prevention and Resolution (“CPR Mediation Procedure”) (www.cpradr.org) before initiating arbitration. The CPR Mediation Procedure shall control, except where it conflicts with these provisions, in which case these
provisions control. The mediator shall be chosen pursuant to CPR Mediation Procedure. The mediation shall be held in New York, New York. 

(ii) Either Party may initiate mediation by written notice to the other Party of the existence of a Dispute. The Parties agree to select a
mediator within [***] of the notice and the mediation will begin [***] after the selection. The mediation will continue until the mediator, or either Party, declares in writing, no sooner than after the conclusion of [***] of a substantive mediation
conference attended on behalf of each Party by a senior business person with authority to resolve the Dispute, that the Dispute cannot be resolved by mediation. In no event, however, shall mediation continue more than [***] from the initial notice
by a Party to initiate meditation unless the Parties agree in writing to extend that period. 
 (iii) Any period of limitations that would
otherwise expire between the initiation of mediation and its conclusion shall be extended until [***] after the conclusion of the mediation. 

(c) Arbitration. If the Parties fail to resolve the Dispute pursuant to Section 18.1(a) or Section 18.1(b), and a Party
desires to pursue resolution of the Dispute, subject to Section 18.5, the Dispute shall be resolved by final and binding arbitration as follows:

Exhibit marked as [***] have been omitted pursuant to a request for confidential treatment and have been filed separately with the Securities and Exchange Commission. 

  
 -98-

 (i) The Dispute shall be finally resolved by arbitration in accordance
with the then-current CPR Rules for Non-Administered Arbitration Rules (“CPR Rules”) (www.cpradr.org), except where they conflict with these provisions, in which case these provisions control.
The place of arbitration shall be New York, New York. All aspects of the arbitration shall be treated as confidential. 
 (ii) Whenever a
Party decides to institute such arbitration proceedings, such Party shall as [***] as practicable, give written notice to that effect to the other Party. The law of this arbitration clause shall be the law of New York, USA, the seat and venue of the
arbitration shall be New York, USA, and the arbitration proceedings shall be conducted in the English language. The arbitrators will be chosen from the CPR Panel of Distinguished Neutrals, unless a candidate not on such panel is approved by both
Parties. Each arbitrator shall be a lawyer with at least fifteen (15) years’ experience with a law firm or corporate law department of over twenty-five (25) lawyers or who was a judge of a court of general jurisdiction. There shall be
three (3) arbitrators for the Dispute, selected as follows: each Party shall select an arbitrator in accordance with the “screened” appointment procedure provided in CPR Rule 5.4, and the chair will be chosen in accordance with CPR
Rule 6.4. If, however, the aggregate award sought by the Parties is less than [***] and equitable relief is not sought, a single arbitrator shall be appointed in accordance with the CPR Rules. Candidates for the arbitrator position(s) may be
interviewed by representatives of the Parties in advance of their selection, provided that all Parties are represented. 
 (iii) The
hearing on the merits shall be concluded within [***] after the initial prehearing conference and the award shall be rendered within [***] of the conclusion of the hearing, or of any post-hearing briefing, which briefing shall be completed by both
sides within [***] after the conclusion of the hearing, unless the arbitrator(s) determine(s), in a reasoned decision, that the interest of justice or the complexity of the case requires that the time limit for concluding the hearing on the merits
or rendering the award be extended. In the event the Parties cannot agree upon a schedule, then the arbitrator(s) shall set the schedule following the time limits set forth above as closely as practical. 

(iv) The hearing on the merits will be concluded in [***] or less, unless the arbitrator(s) determine(s), in a reasoned decision, that the
interest of justice or the complexity of the case requires that the time limit for concluding the hearing on the merits or rendering the award be extended. Multiple hearing days will be scheduled consecutively to the greatest extent possible. A
transcript of the testimony adduced at the hearing shall be made and shall be made available to each Party. 
 (v) The Parties shall allow
and participate in discovery in accordance with the United States Federal Rules of Civil Procedure. Unresolved discovery disputes shall be submitted to the arbitrator(s). 

(vi) The arbitrator(s) shall decide the merits of any Dispute in accordance with the law governing this Agreement, without application of any
principle of conflict of laws that would result in reference to a different law. The arbitrator(s) may not apply principles such as “amiable compositeur” or “natural justice and equity.”

 (vii) The arbitrator(s) are expressly empowered to decide dispositive
motions in advance of any hearing and shall endeavor to decide such motions as would a United States District Court Judge sitting in the jurisdiction whose substantive law governs. 

(viii) The arbitrator(s) shall render a written opinion stating the reasons upon which the award is based. The Parties consent to the entry of
judgment on any award rendered hereunder. Judgment on the award may be entered in any court of competent jurisdiction. 
 (ix) The award of
the arbitral tribunal shall be final and binding upon the Parties, and the prevailing Party may apply to a court of competent jurisdiction for enforcement of such award. When any Dispute occurs and when any Dispute is under arbitration, except for
the matters in Dispute, the Parties shall continue to fulfill their respective obligations and shall be entitled to exercise their rights under this Agreement. Except in a proceeding to enforce the results of the arbitration or as otherwise required
by Applicable Law, neither Party nor any arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written consent of both Parties. Notwithstanding anything to the contrary contained in this Agreement,
each Party to the Dispute shall be entitled to seek provisional remedies, interim measures of protection and emergency relief, if possible, such as attachment, preliminary injunction, replevin or other equitable relief, from the arbitral tribunal or
any court of competent jurisdiction in accordance with the Applicable Laws of that jurisdiction in order to avoid irreparable harm, maintain the status quo, preserve its status and priority as a creditor or preserve the subject matter of the
Dispute. 
 (d) Waivers. EACH PARTY HERETO WAIVES: (I) ITS RIGHT TO TRIAL OF ANY ISSUE BY JURY AND (II) ANY CLAIM FOR
ATTORNEY FEES, COSTS AND PREJUDGMENT INTEREST; PROVIDED, HOWEVER, THAT THE FOREGOING WILL NOT LIMIT A PARTY’S OBLIGATIONS IN RESPECT OF DAMAGES CLAIMED BY A THIRD PARTY. 

 

	18.2.	 Governing Law. 

This Agreement shall be governed by and construed under the laws of the State of New York, without giving effect to the conflicts or choice of laws provision
thereof (“Governing Law”). The United Nations Convention on Contracts for the International Sale of Goods (1980) shall not apply to the interpretation of this Agreement. 

 

	18.3.	 Exclusions. 

Nothing in this Article 18 shall preclude a Party from: (a) seeking and obtaining in any competent court injunctive or equitable relief to preserve the
status quo or prevent immediate harm to the Party; or (b) submitting any dispute, controversy or Claim relating to the scope, validity, enforceability or infringement of any Patents or Trademarks to adjudication in accordance with the
Applicable Laws of the country or jurisdiction in which the relevant patent is pending or has been issued, including before any patent or trademark administrative body in the country in which such Patent or Trademark was granted or arose. The
Parties agree that the venue of any such adjudication involving a patent pending in or issued by the United States will be a U.S. federal

 district court sitting in New York, New York or an appellate body of such court, and for
a patent pending in or issued by any other country, any competent court having jurisdiction over the subject of the Patent controversy or Claim sitting in the capital of such country (or if there is not any such competent court in the capital, a
location reasonably proximate to the capital), and each Party hereby irrevocably submits to the jurisdiction of such courts or administrative bodies. 
  

	18.4.	 Cumulative Remedies. 

Unless expressly stated otherwise in this Agreement, no remedy referred to in this Agreement is intended to be exclusive, but each shall be cumulative and in
addition to, and not in lieu of, any other remedy referred to in this Agreement or otherwise available to either Party under Applicable Law. 
  

	18.5.	 Injunctive Relief. 

Notwithstanding anything to the contrary set forth in this Agreement, the Parties each stipulate and agree that given the nature of the Confidential
Information and Intellectual Property Rights and the competitive damage and irreparable harm that may result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information or Intellectual Property Rights to any Third Party,
monetary damages may not be a sufficient remedy for any breach of Section 4.4, Article 11, Article 12 or Article 13 by a Party. In the case of any such breach or threatened breach, in addition to all other remedies, the non-breaching Party will be entitled to seek equitable relief (including temporary or permanent restraining orders, specific performance or other injunctive relief) for any such breach or threatened breach from
any court of competent jurisdiction without first submitting to the dispute resolution procedures set forth in Section 18.1. 
  

	19.	 GENERAL PROVISIONS 

 

	19.1.	 Assignment. 

Subject to Section 4.6(d) and Section 4.6(e), neither Party may assign its rights or obligations under this Agreement, in whole or in part, without
the other Party’s prior written consent, except that either Party may assign this Agreement, in whole or in part, without the other Party’s consent to: (a) an Affiliate of the assigning Party; or (b) any Third Party successor or
purchaser of all or substantially all of its business or assets to which this Agreement relates, whether in a merger, sale of stock, sale of assets or other similar transaction. In addition, Janssen may, without the prior written consent of
MeiraGTx, assign its rights and obligations, in whole or in part, under this Agreement to a Third Party, where Janssen or its Affiliate is required, or makes a good faith determination based on advice of counsel, to divest any Products in order to
comply with Applicable Law or the order of any Governmental Authority as a result of a merger or acquisition or similar transaction. In any such case, Janssen shall provide MeiraGTx with advance notice of any such assignment. Any permitted assignee
will assume all obligations of its assignor under this Agreement (or related to the assigned portion in case of a partial assignment). For clarity: (i) an assignment to an Affiliate will terminate, and all rights so assigned will revert to the
assigning Party, if and when such Affiliate ceases to be an Affiliate of the assigning Party; and (ii) sublicensing of any licenses granted under this Agreement will be governed by Section 4.1(c) and Section 4.3. Any attempted
assignment in contravention of the foregoing will be null and void. Subject to the terms of this Agreement, this Agreement will be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns.

	19.2.	 Extension to Affiliates. 

Each Party may discharge any obligations and exercise any rights under this Agreement through delegation of its obligations or rights to any of its Affiliates.
Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and will cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any breach by a
Party’s Affiliate of any of such Party’s obligations under this Agreement will be deemed a breach by such Party. Any reference to performance by a Party hereunder includes any performance by its Affiliates. 

 

	19.3.	 Severability. 

If any of the provisions of this Agreement become void or unenforceable as a matter of law, then this Agreement shall be construed as if such provision were
not contained herein, the remainder of this Agreement shall be in full force and effect, and the Parties will negotiate in good faith to substitute any invalid or unenforceable provision with a valid and enforceable provision such that this
Agreement conforms as nearly as possible with the original intent of the Parties. 
  

	19.4.	 Force Majeure. 

If either Party is prevented from performing its obligations under this Agreement due to any contingency beyond its reasonable control (“Force
Majeure”), including acts of Governmental Authorities, any war, terrorism, hostilities between nations, civil commotions, riots, national industry strikes, sabotage, fire, floods and acts of nature such as typhoons, hurricanes, earthquakes,
or tsunamis, the Party so affected shall not be responsible to the other Party for any delay or failure of performance of its obligations hereunder, for so long as and to the extent that such Force Majeure prevents such performance. If a Force
Majeure arises, the Party immediately affected thereby shall give prompt written notice to the other Party specifying the Force Majeure event complained of, and shall use Commercially Reasonable Efforts to avoid or remove such causes of non-performance and to mitigate the effect of such occurrence to resume performance of its obligations with reasonable dispatch. 
  

	19.5.	 Waivers and Amendments. 

The delay or failure of any Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a
waiver of that right, term or condition or excuse a similar subsequent failure to perform any such term or condition by the other Party, and no waiver shall be effective unless it has been given in writing and signed by the Party giving such waiver.
No waiver by either Party of any condition or of the breach of any term contained in this Agreement, in any one (1) or more instances, will be deemed to be, or considered as, a further or continuing waiver of any such condition or of the breach
of such term or any other term of this Agreement. No provision of this Agreement may be amended or modified other than by a written document signed by authorized representatives of each Party.

	19.6.	 Relationship of the Parties. 

Nothing contained in this Agreement shall be deemed to constitute a partnership, joint venture, or legal entity of any type between MeiraGTx and Janssen or
their respective Affiliates, or to constitute one as the agent of the other. Moreover, each Party agrees not to construe this Agreement, or any of the transactions contemplated hereby, as a partnership for any tax purposes. Each Party shall act
solely as an independent contractor, and nothing in this Agreement shall be construed to give any Party the power or authority to assume or create any obligations on behalf of or in the name of the other Party or to bind the other Party to any
contract, agreement or undertaking with any Third Party.
