2.5.2 PARI and its Affiliates shall have the right to reference ProQR’s, its Affiliates’ and its Permitted
Sublicensees’ IND and NDA and other related or corresponding filings with Regulatory Authorities pertaining to the Drug Product, as filed by ProQR, its Affiliates or its Permitted Sublicensees with Regulatory Authorities from time to time, to
the extent necessary for PARI and/or its Affiliates to obtain Regulatory Approval for the Device for exclusive use with the Drug Product in the Field in the Territory solely on ProQR’s, its Affiliates’ or its Permitted Sublicensees’
behalf. ProQR, its Affiliates and its Permitted Sublicensees shall provide PARI and its Affiliates with reasonable access to the IND and NDA files and shall, from time to time make available to PARI and its Affiliates copies of such selected
portions of such IND and NDA files as they may request (such request may not be unreasonably denied), in each case to the extent necessary for PARI and/or its Affiliates to obtain Regulatory Approval for the Device for exclusive use with the Drug
Product in the Field in the Territory. 
 2.6 Option for Additional Drug Products in the Field. 

(a) Subject at all times to ProQR’s compliance with the terms of this Agreement, PARI hereby grants to ProQR (but not to
any Permitted Sublicensee), during the Royalty Term, an option to negotiate in good faith an Exclusive, sublicensable (in accordance with Section 2.2 and Section 2.3), transferable (other than to a PARI Competitor and
otherwise in accordance with Sections 13.4 and 13.10), Royalty-bearing license under the Licensed Intellectual Property to Exploit one or more Option Drug Products for use exclusively with the Device in the Field in the Territory. In the
event that ProQR wishes to exercise its option pursuant to this Section 2.6, then ProQR shall provide written notice thereof to PARI, and the Parties agree to promptly execute an amendment to this Agreement in order to incorporate such
Option Drug Product in the definition of Drug Product, or should ProQR so wish, promptly execute a separate agreement identical in all respects to this agreement except for the definition of Drug Product which shall be replaced by the definition of
the Option Drug Product in line with the current definition of Drug Product. All other provisions of this Agreement shall remain in full force and effect and apply to the exercised Option Drug Product. 

(b) In the event a third party contacts PARI, or if PARI desires to grant to a third party an Exclusive license to Exploit one
or more of the Option Drug Products (the “Third Party Option Drug Product License”), PARI shall offer the Third Party Option Drug Product License, on the same terms and conditions as offered by or to such third party, to ProQR (the
“Right of First Refusal”). If ProQR notifies PARI in writing within thirty (30) days of its receipt of PARI’s notice that ProQR accepts such terms, the Parties shall enter into an agreement on such terms within thirty
(30) days after ProQR’s exercise of the Right of First Refusal. If ProQR does not notify PARI in writing within such thirty (30)-day period that ProQR accepts such terms and exercises the Right of First Refusal, then PARI shall be free to
grant the particular Third Party Option Drug Product License on the same terms to such third party, and ProQR shall have no further rights with respect to the particular Option Drug Product, except upon termination or expiration of such Third Party
Option Drug Product License, in which case ProQR’s rights in respect of such Option Drug Product shall revive.

control the marking, labeling, CE conformity declaration and technical documentation with respect to the Device. In light of ProQR’s taking the lead in FDA correspondence for a Combination
Product, PARI will be allowed to attend (part of the) meetings with Regulatory Authorities if the Device will be the subject matter at such (part of the) meeting. 

(d) Notwithstanding the foregoing, if a Regulatory Authority requests the filing of a Combination Product: (i) ProQR will
support PARI in accommodating such requirement; (ii) PARI will support ProQR in making and prosecuting such filing, including with respect to the preparation, provision and filing of all necessary Device documentation, (iii) PARI will have
the right to review, comment upon, and approve (such approval not to be unreasonably withheld) any portion of such filings bearing on the Device prior to such filing; and (iv) the Parties will work in good faith to allow for PARI to implement
any necessary changes to the Device or any Accessory accordingly. 
 (e) PARI shall control all manufacturing activities
relating to the Device or any Accessory; provided that PARI shall (i) keep ProQR reasonably informed with respect to such activities, and (ii) not take any action or fail to take any action which would be reasonably likely to have a
material adverse effect on the development of the Product and manufacture thereof. 
 3.1.2 New Features and Design
Improvements. 
 (a) General. Subject to Section 3.4, if PARI develops or obtains rights to an
incremental (minor) Improvement to the Device or any Accessory, then PARI shall only incorporate such Improvement therein if (i) PARI is not contractually prohibited from doing so by the agreement under which such Improvement was developed,
(ii) PARI generally incorporates such Improvement into the eFlow Technology Nebulizer and/or the Accessory, as applicable, for use in the Field, (iii) it is consistent with the specifications agreed to by the Parties and the applicable
regulatory requirements, (iv) it is consistent with the terms of the Supply Agreement, including but not limited to any acceptance criteria contained therein and (v) it does not interfere with ProQR’s regulatory pathway as has been
communicated to PARI from time to time prior to any such incorporation. If an Improvement is not an incremental Improvement (e.g., a major Improvement), then PARI shall provide ProQR with an opportunity (to the extent PARI is not contractually
prohibited from doing so) to review such Improvement for a period of ninety (90) days from receipt of a detailed description of such Improvement and a plan for development of such Improvement and possible incorporation into the Device or any
Accessory for ProQR to determine whether it wishes to have such Improvement incorporated in the Device or Accessory, as applicable, and thereby be incorporated into the Licenses granted pursuant to Section 2.1.1 (with respect to any
Improvement to the Device) or Section 2.1.2 (with respect to any improvement to an Accessory), as applicable, and shall be included in the PARI Patents, and as such shall extend the Royalty Term accordingly. If ProQR determines (by
giving written notice to PARI) within such ninety (90) day period that it desires to benefit from the Improvement and include the Improvement in the Device or any Accessory, such Improvement shall be automatically included in PARI Know-How and
PARI Patents, as applicable, and with respect to any such Improvement to an Accessory, such Accessory shall be automatically included in the Accessory Know-How and Accessory Patents. If ProQR does not give written notice to PARI within the ninety
(90) day period of its desire to benefit from the Improvement, ProQR shall be deemed to have rejected the Improvement and PARI shall have no obligation to include the Improvement in the Device or Accessory, as applicable. For the avoidance of
doubt, PARI shall incorporate major Improvements only if ProQR shall not have objected in writing to such incorporation on reasonable grounds.

separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 

 (b) Device Development. The Parties will work together in good faith
to customize the Device, if required, for clinical trials and commercialization in accordance with this Agreement. Notwithstanding anything to the contrary contained herein, PARI shall exclusively own and be responsible for the design, development,
testing, tooling and manufacturing related to the Device. ProQR may from time to time submit to PARI a written request for modification(s) to the Device or any Accessory. PARI shall consider in good faith such request and respond to ProQR based on
the costs involved, contractual obligations and other business factors. Any such requested modification(s) shall be subject to mutual written agreement of the Parties ( “Statement of Work”) and be in accordance with this Agreement.
For clarity, costs for the optimization of the Device and all project management and technical support, at the hourly rate of [***] per billable hour, shall be covered by ProQR. Without limiting the foregoing sentence, ProQR will cover all costs for
any drug- or patient population specific adaptation or testing, including, but not limited to, human factor and usability testing, aerosol characterization experiments with the Drug Product and the Device, and Device customizations or other services
requested by ProQR in writing. PARI shall use Commercially Reasonable Efforts to complete such agreed-upon services in accordance with the timeline(s) set forth in the applicable Statement of Work. 

(c) ProQR will reimburse PARI for project management and technical support to support the collaboration and other services
requested by ProQR at an hourly rate of [***] pursuant to Statements of Work to be established by the Parties promptly after the Effective Date 

(d) ProQR shall pay PARI for all services on a time and materials basis. ProQR shall make payment of such service fees and
costs to PARI within thirty (30) days of receipt from PARI of a reasonably detailed invoice summarizing the work performed and expenses incurred. Any undisputed payments or portions thereof due under this Section 3.1.2, which are
not paid when due, shall bear interest equal to the base interest rate as reported by the German Federal Bank (Bundesbank; www.bundesbank.de), on the date such payment is due, plus an additional eight percent (8%) per year, calculated on
the number of days such payment is delinquent. If such unpaid, undisputed payment is a material default, taking into account the total amounts paid or to be paid over all of the Statements of Work, then PARI may request reasonable assurances that
ProQR shall continue to pay ongoing fees and if not received, PARI may suspend further performance of such Statements of Work until such assurances are received or such default is paid. This Section shall not limit other remedies available to PARI
under this Agreement. In the event of any conflict between the terms of this Agreement and a Statement of Work, the terms of this Agreement shall control except (i) in the case of pricing, in which case the Statement of Work shall control, or
(ii) if the Statement of Work explicitly states that it is modifying a particular provision of this Agreement and such Statement of Work is executed by the Chief Executive Officer of ProQR and the President of PARI. 

3.2 Management  

3.2.1 Joint Advisory Committee. Promptly after the Effective Date, ProQR and PARI will establish a joint advisory
committee (the “Joint Advisory Committee” or “JAC”), comprising an equal number of members chosen by each Party, to oversee, review and coordinate the activities of the Parties under this Agreement, including the
development and manufacture of the Product. The JAC shall be responsible for: (a) overseeing the activities of the Parties related to development, regulatory and commercialization matters that would benefit of each other’s input;
(b) resolving disputes and disagreements under this Agreement; and (c) undertaking or approving such other matters as are specifically provided for the JAC under this Agreement. JAC

separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 

 
may develop a full charter for the Joint Advisory Committee, and obtain written approvals from the CEO or President of the Parties. JAC meetings shall be held as often as the Parties mutually
agree are necessary but not less than twice a year and may be by conference call, video conferencing or face-to-face. Written minutes of all meetings will be provided within ten (10) business days of the meeting/teleconference to the members of
the JAC. 
 3.2.2 Decision Making. Decisions that benefit of the input from both parties shall be made through the
Joint Advisory Committee. Such decisions shall be made by the members in accordance with the charter referred to in the previous section. As a guiding principle, matters concerning Drug Product or Combination Product (excluding the Device component
thereof) shall be decided by ProQR members alone. Matters concerning the Device will be decided by PARI members. Voting members shall be present in person or by other means (e.g., teleconference) at any meeting, with at least one representative from
each Party participating in such vote. In the event that the JAC is unable to reach a decision with respect to a particular matter, then either Party may, by written notice to the other, have such matter referred to the President or Chief Executive
Officer of each of the Parties, who shall discuss and attempt to resolve such matters to the Parties’ mutual satisfaction within thirty (30) days thereafter. If the Parties are unable to resolve such dispute in accordance with this
Section 3.2.2, Section 12.2 of this Agreement shall apply. 
 3.2.3 Reserved Rights.
Notwithstanding the foregoing, however, in the event either Party reasonably determined that a final decision of the JAC pursuant to Section 3.2 will result in a hazardous or unsafe Device or Drug Product, or infringement of a third
party’s patent rights, then that first Party shall provide the JAC with information supporting its belief. Upon delivery of such information, and discussion with the second Party at the JAC, the first Party shall have the right to refrain from
implementing such decision in its performance of this Agreement, provided that if the second Party in good faith disagrees with the basis of such determination, the Parties shall resolve the disagreement in accordance with Section 3.2.2.
Notwithstanding the foregoing, nothing in this Section 3.2 shall be deemed to require either Party to take any action that it believes is unlawful. 

3.2.4 Limited Authority. The decisions of the JAC, whether under this Section 3.2 or under any other section
of this Agreement, shall not have the power to amend or contradict the terms of this Agreement or the agreed Statements of Work, nor substitute for either Party’s ability to exercise any right, nor excuse the performance of any obligation, set
forth in this Agreement. 
 3.2.5 Conduct of the Project. Subject to the terms and conditions of this Agreement, each
Party shall use Commercially Reasonable Efforts to perform the activities assigned to it under a Statement of Work in accordance with the specifications, timelines and budgets set forth therein, under the supervision of the JAC. Each Party shall
keep the JAC informed as to its progress under a Statement of Work.

 3.7.4 Notice and Cure. In the
event PARI, acting in good faith, makes a reasonable case that ProQR or a Permitted Sublicensee, as applicable, has failed to use such Commercially Reasonable Efforts, PARI shall notify ProQR. ProQR shall have a period of ninety (90) days
thereafter to resume, or cause the Permitted Sublicensee to resume, using such Commercially Reasonable Efforts. 
  

	4.	PAYMENTS 

 4.1 Up-Front Payment. ProQR shall pay to PARI a non-refundable
up-front payment of [***] within thirty (30) days after the Effective Date. 
 4.2 Royalties. In consideration of the License
granted under this Agreement and subject to the terms and conditions of this Agreement, until the expiration of the Royalty Term, ProQR (or its Permitted Sublicensees pursuant to Section 10.5.6, if applicable) shall pay to PARI a royalty
(“Royalty”) on Net Sales of the Drug Product sold for use with the Device, subject to reduction as set forth in Section 4.4, as set forth below: 
  

			
	Net Sales	  	Royalty Rate
	Annual Net Sales of less than or equal to Euro [***]	  	[***]
	Annual Net Sales in excess of Euro [***] and up to Euro [***]	  	[***]
	Annual Net Sales in excess of Euro [***]	  	[***]

 For clarification purposes, Royalties are payable on an incremental basis, i.e., if the annual Net Sales
amount to [***], [***] are payable on [***] and [***] are payable on [***].

 4.4 Permitted Reductions in Royalty. 

(a) If ProQR is required to pay third party royalties for sales of the Drug Product based on intellectual property licenses
ProQR has to enter into with such third parties after the Effective Date, but only for as long as ProQR or its Affiliates or Permitted Sublicensees, as applicable, exclusively use the Device with the Drug Product, the following applies. If the total
amount of royalties, thus the Royalty under this Agreement and such third party royalties, exceed [***] of the Net Sales of the Drug Product, ProQR will cover [***] of the royalties in excess of [***] and the other [***] will be shared, by lowering
the applicable royalties, including the Royalty, on a pro rata basis, based on their respective percentages, among all licensors, including PARI. However, such deduction shall never lead to a Royalty which is lower than [***] of the amount that it
would have been without the deduction, including any deductions pursuant to paragraph (b) below. The applicable third party royalties shall be those that accrue in the same reporting period of the royalty reports with respect to the same Net
Sales as the Royalty and shall be calculated as provided in the relevant third party license agreement(s). 
 By means of
example, if ProQR has to pay third party royalties for sales of the Drug Product to three other licensors in addition to PARI in the amount of [***] each, for total royalties to all four licensors (including PARI) of [***] in the aggregate, then the
Royalty shall be as follows: [***] less [***] = [***], of which [***] will be absorbed by ProQR and the other [***] will be shared by all four licensors on a pro rata basis, i.e. [***] each, resulting in the Royalty being [***] - [***] = [***].
 ProQR represents and warrants that, as of the
Effective Date, the third party royalties plus the Royalty ProQR, its Affiliates and sublicensees, will contractually or otherwise be required to pay related to sales of the Drug Product, amount to less than 5% in the aggregate. In addition, ProQR
has no knowledge of any requirement or desire, and has no current intent, to pay any additional third party royalties related to sales of the Drug Product. 

(b) If ProQR is required to and actually incurs any expenses or makes any payments pursuant to the second to last sentence of
Section 7.3.6, then the Royalty shall be reduced, up to [***] but subject to the provisions of paragraph (c) below, in order for ProQR to recover its paid expenses and upon its recovery thereof, any such Royalty reduction shall
immediately cease to be in effect. 
 (c) Notwithstanding anything to the contrary in this Agreement, in no event shall the
reductions in the Royalty pursuant to paragraphs (a) and (b) above, in the aggregate, be more than [***] of the original Royalty set forth in Section 4.2. 

4.5 Payment and Reports. Within forty-five (45) days after the end of each calendar quarter in which Net Sales have occurred,
ProQR shall submit to PARI a written report setting forth for such preceding calendar quarter the Net Sales received and the calculation of the Royalty payable to PARI pursuant to Section 4.2. Such report shall be accompanied by the
total Royalty due, if any, to PARI pursuant to Section 4.2 and be broken down by country or territory and by Drug Product, including allowed deductions. If the Royalty paid for any Year of Sales set forth in the table in
Section 4.3 is less than the applicable Annual Minimum Royalty, for such Year of Sales, then forty-five (45) days after the

 Portions of the exhibit, indicated by the mark “[***],” were omitted and have been filed
separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 

 
end of such Year of Sales, ProQR shall pay to PARI the difference between the applicable Annual Minimum Royalty and the actual Royalties previously paid for such Year of Sales. All payments shall
be made in Euros. Sales made in currencies other than Euros shall be converted to Euros on the basis of the average exchange rate for the calendar quarter in which such sales were made. Such calendar average exchange rate shall be calculated by
averaging monthly exchange rates published by The Financial Times. 
 4.6 Record Keeping. ProQR shall keep, and shall cause its
Affiliates and Permitted Sublicensees to keep, complete and accurate books of accounts of record in connection with the use, sublicensing and sale of Products to permit verification of payments made hereunder. Such records shall be maintained for a
period of at least five (5) years from the date on which they were generated. 
 4.7 Audit Rights. PARI shall have the right to
have an independent third party nationally-recognized accounting firm reasonably acceptable to ProQR access the books and records of ProQR, its Affiliates and Permitted Sublicensees solely to the extent necessary to verify the accuracy of the
reports and payments made hereunder. Such access shall be conducted upon reasonable written notice to ProQR, its Affiliates and Permitted Sublicensees and during such parties’ normal business hours. Such access shall not be more frequent than
once per calendar year and may occur only with respect to the immediately preceding thirty-six (36) months. The auditing Party shall be required to sign a confidentiality agreement for the benefit of ProQR. If any audit discloses that the
payments by ProQR to PARI are incorrect in ProQR’s favor, then ProQR shall pay any amount due to PARI within ten (10) days after receipt of the necessary documentation of the amount owed. If any audit discloses that the payments by ProQR
to PARI are incorrect in PARI’s favor, then ProQR shall have the right to credit the amount of the overpayment against each subsequent quarterly payment due to PARI until the overpayment has been fully applied. If the overpayment is not fully
applied prior to the final quarterly payment of Royalties due hereunder, PARI shall promptly refund an amount equal to any such remaining overpayment. If PARI’s audit demonstrates an underpayment of more than five percent (5%) for the
payment due to PARI during the audited period, ProQR shall be liable for PARI’s reasonable cost of the audit that discovered such underpayment. Otherwise, PARI shall bear the costs of such audits. ProQR shall have the right to dispute any such
audit results in accordance with Section 12. 
 4.8 Withholding Taxes. Where required to do so by applicable Law or order
of a governmental body, ProQR shall withhold taxes required to be paid to a taxing authority in connection with any payments to PARI hereunder, and, upon request of PARI, ProQR shall furnish PARI with satisfactory evidence of such withholding and
payment. ProQR shall, and shall cause its Affiliates and its Permitted Sublicensees to, cooperate with PARI before or after the payment of such tax in obtaining exemption from withholding taxes where available under applicable Law and/or receiving a
full refund of such withholding tax or claim a foreign tax credit. 
 4.9 Late Payments. Any Royalties, Annual Minimum Royalties or
other payments due PARI under this Agreement or any portion thereof which are not paid when due, shall bear interest equal to the base interest rate as reported by the German Federal Bank (Bundesbank; www.bundesbank.de), on the date such
payment is due, plus an additional eight percent (8%) per year, calculated on the number of days such payment is delinquent. This Section 4.9 shall not limit other remedies available to PARI under this Agreement. 

4.10 Alternative Device. In the event ProQR, following its receipt of a first marketing approval for the sale of the Drug Product in a
Major Country, decides to no longer exclusively use the Device but instead uses an alternative device, either alone or in addition to the Device, then, in ProQR’s discretion, ProQR shall either (x) continue to pay Royalties and Annual
Minimum Royalties, or (y) terminate this Agreement and the License pursuant to Section 10.4(a) and pay to PARI within three (3) business days the amount of [***] (the “Compensatory Payment Amount”); provided,
however, that if the

separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 

 
payment of the Compensatory Payment Amount is due after the fifth Year of Sales, then the Compensatory Payment Amount shall be [***] for each Year of Sales thereafter so that the Compensatory
Payment Amount shall be [***] if payment is due after the ninth (9th) Year of Sales. 
  

	5.	PATENT RIGHTS 

 5.1 Patent Prosecution and Maintenance. PARI shall have the
exclusive right and obligation to control prosecution, maintenance, challenges against validity and unenforceability or patentability with respect to the Device, any Accessory and the Licensed Intellectual Property, and ProQR will assist PARI, at
PARI’s request and expense, in any such activities and ProQR shall have the exclusive right and obligation to control prosecution, maintenance, challenges against validity and unenforceability or patentability with respect to the ProQR
Technology and the Drug Product and Combination Product (but only the drug formulation component thereof), and PARI will assist ProQR, at ProQR’s request and expense, in any such activities. 

5.2 Enforcement. 

5.2.1 If either Party should become aware of any infringement or misappropriation or threatened infringement or
misappropriation of the other Party’s intellectual property rights, including Know-How, contemplated herein by a third party that could reasonably be expected to adversely affect the Drug Product or Combination Product (“Product-Specific
Infringement”), it shall promptly notify the other Party in writing and provide any information available to that Party relating to such alleged Product-Specific Infringement. 

5.2.2 PARI shall have the initial right (but not the obligation) to bring and/or control any enforcement action directed to an
asserted Product-Specific Infringement pertaining primarily to the Device, the eFlow Technology Nebulizer, any Accessory and any PARI intellectual property, including Know- How, and any Improvements to any of the forgoing. ProQR shall have the
initial right (but not the obligation) to bring and/or control any enforcement action directed to an asserted Product-Specific Infringement pertaining primarily to the Drug Product, Combination Product (but only the drug formulation component
thereof) and any ProQR intellectual property, including Know-How. The Party controlling the enforcement action shall keep the other Party reasonably informed of the progress thereof. 

5.2.3 If the Exploitation of the Products results in a claim alleging patent infringement against either Party (or its
Affiliates or Permitted Sublicensees), such Party shall promptly notify the other Party hereto in writing. ProQR shall have the initial right to defend and control the defense of any infringement claim pertaining primarily to the Drug Product,
Combination Product (but only the drug formulation component thereof) and ProQR intellectual property, including Know-How, and PARI shall have the initial right to defend and control the defense of any infringement claim pertaining primarily to the
Device and any PARI intellectual property, including Know-How, including any Improvements to the foregoing. Each Party (i) may use counsel of its own choice as applicable, and (ii) keep the other Party informed of all material developments
in connection with any such claim. 
 5.2.4 Licensed Intellectual Property not Owned by PARI. To the extent that any
Licensed Intellectual Property is licensed by PARI from a third party, PARI shall comply with the above provisions to the fullest extent permissible under such licenses. 

5.3 Settlements Affecting PARI’s Rights. Notwithstanding anything to the contrary contained in this Agreement, the Parties
acknowledge and agree that ProQR shall not have the right to

enter into any license, settlement or other disposition of a Product-Specific Infringement that affects PARI’s rights in the Licensed Intellectual Property and/or any payments due to PARI
pursuant to this Agreement. 
  

	6.	CONFIDENTIAL INFORMATION 

 6.1 Non-use and Non-disclosure Obligations. Each of
PARI and ProQR shall, and ProQR shall cause its Permitted Sublicensees to, use any Confidential Information received by it from the other Party solely in connection with exercise of their respective rights and/or performance of their respective
obligations under this Agreement and the Supply Agreement, and shall not disclose such Confidential Information to any third party, without the prior written consent of the other Party. These obligations shall survive the expiration or termination
of this Agreement for a period of ten (10) years. These obligations shall not apply to information that: 
 6.1.1 is
known by the receiving Party at the time of receipt and not through a prior disclosure by the disclosing Party; 
 6.1.2 is
at the time of disclosure or thereafter becomes published or otherwise part of the public domain through no breach of this Agreement by the receiving Party; 

6.1.3 is subsequently disclosed to the receiving Party without restriction by a third party having the right to make such a
disclosure; or 
 6.1.4 is developed by the receiving Party independently of information received by it from the disclosing
Party hereunder. 
 6.2 Required Disclosure. In order to provide the disclosing Party an opportunity to seek a protective order or
the like with respect to certain Confidential Information of the disclosing Party, the receiving Party may disclose Confidential Information to the extent that it is required by Law or order of any governmental authority or agency, including the
Securities and Exchange Commission, to be disclosed by a Party; provided that the receiving Party shall apply for confidential treatment of this Agreement to the fullest extent permitted by law, shall provide the other Party a copy of the
confidential treatment request far enough in advance of its filing, if reasonably practical, to give the other Party a meaningful opportunity to comment thereon, and shall use reasonable efforts to incorporate in such confidential treatment request
any reasonable comments of the other Party. 
 6.3 Permitted Disclosure. Notwithstanding Section 6.1, Confidential
Information provided under this Agreement by a disclosing Party may be disclosed to employees, agents, board members, Affiliates or suppliers of the receiving Party, but only to the extent permitted or required to accomplish the purposes of this

other announcements or disclosures relating to the existence and terms of this Agreement or the transactions contemplated hereby shall be reviewed in advance by, and shall be subject to the written approval of, both Parties; provided that such
publicity, press releases and other announcements shall not disclose any Confidential Information of the other Party hereunder and shall give appropriate attribution to the Product(s) and the other Party’s role(s) in the project contemplated
herein. Each Party shall provide the other Party an opportunity to review and comment on the language of such attribution prior to first use thereof in a press release or other public disclosure. PARI’s contribution to the Product shall be
acknowledged in all press releases and any presentations and publications of ProQR, its Affiliates and Permitted Sublicensees. Either Party may disclose the existence of this Agreement and the terms and conditions hereof, without the prior written
consent of the other Party, as may be required by applicable Law, in which case the Party seeking to disclose such terms and conditions shall give the other Party reasonable advance notice and review of any such disclosure and shall seek
confidential treatment of such information to the extent possible under applicable Law.

in any material way, and (ii) do not conflict with, violate or breach or constitute a default or require any consent under, any contractual obligation, agreement, license, or any written instrument with any third party or court or
administrative order by which such Party is bound. 
 7.3 Intellectual Property. 

7.3.1 PARI represents and warrants that, to its knowledge, Schedule B sets forth a true, correct and complete list of all PARI
Patents comprising the Licensed Intellectual Property that are necessary or useful to Exploit the Device in the Territory. 

7.3.2 As of the Effective Date, PARI represents and warrants that the Licensed Intellectual Property is free and clear of all
Encumbrances. 
 7.3.3 As of the Effective Date, PARI represents and warrants that all registrations with and applications to
governmental or regulatory bodies in respect of the Licensed Intellectual Property in the Territory required to be made by PARI, or made at its direction and under its control, are in full force and effect and PARI has taken all commercially
reasonable actions required to maintain their validity and effectiveness. 
 7.3.4 PARI has not received any notice that it
is, in default (or with the giving of notice or lapse of time or both, would be in default) under any license with respect to the Licensed Intellectual Property. 

7.3.5 To the knowledge of PARI, as of the Effective Date, in the Field in the Territory, no third party device infringes upon,
or misappropriates the Licensed Intellectual Property rights. 
 7.3.6 PARI represents that it has not received any currently
outstanding or unresolved written notice from third parties that its Device or any other aspect of the Licensed Intellectual Property (i) infringes any third party Patents; (ii) misappropriates any Know-How belonging to a third party, or

causes, or could reasonably be expected to cause, ProQR’s use of the Device in accordance with the terms of this Agreement to be disrupted, where and to the extent possible, PARI shall, at its option and on a country-by-country basis,
(x) provide ProQR with access to components or entire Nebulizers which are functionally equivalent to the Device whilst still meeting the specifications agreed to by the Parties, without additional charge to ProQR; or (y) modify the
infringing portions of the Device so that such portions are non-infringing whilst still meeting the specifications agreed to by the Parties, or (z) obtain a license of intellectual property due to the actual infringement or misappropriation by
the Device at PARI’s cost and expense. For the avoidance of doubt, any measure taken by PARI on ProQR’s behalf in accordance with subsection (x) – (z) above shall not add to the license cost or the total royalty burden
incurred by ProQR. In case PARI fails to take action in accordance to this section resulting in ProQR being prohibited to sell the Device or

separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 

 
the Combination Product (i.e., as a result of a court imposed injunction), then ProQR shall be permitted to take such actions it reasonably believes, acting in good faith, to avoid such an
injunction, provided, however, that ProQR shall not enter into any license agreement or any other settlement agreement with the third party alleging infringement without PARI’s prior written consent, such consent not to be unreasonably
withheld, delayed or conditioned. If ProQR takes any of these measures it shall be fully reimbursed by PARI, including for any additional license costs or royalty burden going forward as set forth in Sections 4.4(b) and (c) above. 

 

	8.	SUPPLY 

 8.1 Supply Agreement. PARI shall control and be responsible for all
manufacturing pertaining to the Device and Accessories. The Parties shall enter into a definitive commercial supply agreement (the “Supply Agreement”) providing for the supply of Devices, Handsets, and Accessories from PARI or its
contract manufacturer to, at ProQR’s election, ProQR, its Affiliates, or its Permitted Sublicensees, and shall use Commercially Reasonable Efforts to execute such Supply Agreement as soon as reasonably practicable and in any event prior to the
initiation of the earliest Phase 3 Clinical Trial for the Drug Product unless otherwise mutually agreed to by the Parties. The Parties shall negotiate with one another in good faith with respect to the Supply Agreement. The Supply Agreement shall
remain in full force and effect through the Royalty Term and thereafter as long as ProQR and its Permitted Sublicensees in the aggregate will annually order a minimum number of [***] handsets per year on a global basis at a price of [***] per
handset plus the rate of price increase in Germany between the Effective Date and the year in which such minimum amount is to be purchased (published by the Statistisches Bundesamt under
www.destatis.de/EN/FactsFigures/Indicators/ShortTermIndicators/Prices/pre110.html). For the avoidance of doubt, the Supply Agreement shall only terminate if, after having been notified by PARI of ProQR’s failure to order the [***]
minimum amount of handsets, ProQR fails to order such minimum amount within a period of 90 days following receipt of such notification. The Supply Agreement shall incorporate the terms set forth in Schedule E, the terms set forth below and
other customary terms for a supply relationship of this nature, and shall include additional provisions sufficient to protect ProQR in the event of a shortfall of Devices, Accessories or any components thereof and contain provisions related to time
of delivery of sufficient quantities of Devices and Accessories. 
 8.2 Clinical Development. PARI shall use Commercially Reasonable
Efforts to manufacture and supply the Device, Handsets, and Accessories to ProQR, its Affiliates, or its Permitted Sublicensees for use during clinical trials of the Drug Product by, or on behalf of, ProQR for a price of (i) [***] per Handset,
and (ii) [***] per Device, in each case excluding any shipping or storage costs. The foregoing prices are for Devices without any monitoring capability. PARI shall use Commercially Reasonable Efforts to provide one hundred percent
(100%) of ProQR’s, its Affiliates’, or its Permitted Sublicensees’ requirements for such clinical trials. 
 8.3
Commercial.  
 8.3.1 Manufacture and Supply of the Device. The Parties agree that PARI shall manufacture and supply
to ProQR (or its designee) the Device for commercial use with the Drug Product at the price (“Device Price”) of [***] per eBase Starter Kit (including eBase controller, nebulizer connection cable, batteries, mains adapter, Easycare
membrane cleaning aid (but excluding Handset)). The Device Price is ex works Incoterms 2010 (“EXW”) PARI’s manufacturing or distribution dock (i.e. does not include distribution costs). 

8.3.2 Manufacture and Supply of Handsets. The Parties agree that PARI shall manufacture and supply to ProQR (or its designee)
replacement Handsets intended for commercial use with the Drug Product (as an inclusion in the monthly Drug Product Package) at the price (“Handset Price”) of [***] per Handset.

 Portions of the exhibit, indicated by the mark “[***],” were omitted and have been filed
separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 

 8.4 Forecasts. ProQR shall submit rolling quarterly forecasts of its anticipated
requirements of Devices and Handsets for the next 12 months. 
 8.5 Commercial Specifications. The Supply Agreement shall set forth
any final product specifications for the Device as determined in accordance with this Agreement. The Supply Agreement may also set forth any additional Device specifications and other characteristics and materials for the Device (“Additional
Specifications”), as mutually agreed to by the Parties. Any changes in such Additional Specifications that could have a material adverse effect on the development of the Product and manufacture of the Device, including the quality,
reliability, robustness or user interface of the Device, or which would otherwise have an adverse effect on the Drug Product when used with the Device, shall require the prior written approval of ProQR as shall be described in more detail in the
Supply Agreement. 
 8.6 Other Supply Terms. Other customary supply terms shall include quality, acceptance, invoicing and payment,
inspection and optimization, repair, product recalls, adulteration, misbranding, product warranties, notice and cure periods, trademark license and usage guidelines, co-branding rights, representations and warranties (including with respect to the
final design of the Device), indemnities (including product liability indemnity from PARI for the Device), remedies, force majeure, termination provisions and provisions with respect to an appropriate back-up plan to provide reasonable assurances of
continuity of supply of the Devices, all as mutually agreed to by the Parties. 
 8.7 Adverse Event Reporting. This
Section 8.7 shall only apply with respect to the conduct by, or on behalf of, ProQR of clinical trials with respect to the Products. Adverse event reporting with respect to the Products shall otherwise be conducted in accordance with the
terms set forth in the Supply Agreement or in a safety data exchange agreement in which the Parties may enter into for the commercialization of the Products. Unexpected serious adverse events that are made known to either Party (or to a Permitted
Sublicensee) and that are considered to be related to the Drug Product or the Device, shall be reported to the other Party on an expedited basis, and at least within two (2) business days of such Party (or a Permitted Sublicensee) becoming
aware of the unexpected serious adverse event as a result of notification from an institutional review board (IRB), Regulatory Authority or participating investigators. An unexpected serious adverse experience is defined as any adverse drug
experience, the specificity or severity of which is not consistent with the current Investigator Brochure for a clinical trial, or, if an Investigator Brochure is not required or available, the specificity or severity of which is not consistent with
the risk information described in the general investigational plan or elsewhere in the current application, as amended. Unexpected, as used in this definition, refers to an adverse drug experience that has not been previously observed (e.g.,
included in the Investigator Brochure) rather than from the perspective of such experience not being anticipated from the pharmacological properties of the pharmaceutical product. In the case of a clinical trial, an unexpected serious adverse event
would, for example, be as assessed by the investigator and or the sponsor or authorized person without breaking the blind and would qualify for expedited reporting. An unexpected serious adverse event shall be reported by ProQR to the appropriate
institutional review board, Regulatory Authority, investigator and PARI. 
 8.8 Restrictions on Use. The following provisions in this
Section 8.8 shall only apply from the Effective Date until the First Commercial Sale for the first Drug Product. From such First Commercial Sale and thereafter, the provisions set forth in the Supply Agreement shall govern the Parties
accordingly. 
 (a) PARI represents and warrants that the manufacturing of the Device complies at all times with all
applicable Laws and standards valid in the Territory.

 Portions of the exhibit, indicated by the mark “[***],” were omitted and have been filed
separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 

 
Notwithstanding PARI’s obligations pursuant to the previous sentence, ProQR, its Affiliates and Permitted Sublicensees will use the Device in compliance with all applicable Laws and
standards valid in the country where the Device is used. ProQR, its Affiliates and Permitted Sublicensees intend to conduct clinical trials utilizing the Device, including, for example, those relating to research involving the use of humans or
animals and will not engage in any such clinical trials without first obtaining necessary approval from its relevant ethics committee(s) such as, but not limited to, the Institutional Review Board. The Device shall not be used by ProQR, its
Affiliates and Permitted Sublicensees directly or indirectly for any purpose other than the clinical trials. 
 (b) ProQR,
its Affiliates and Permitted Sublicensees shall retain control of the Device and shall not distribute or release the Device to any person or entity other than ProQR’s, its Affiliates’ and Permitted Sublicensees’ or the clinical trial
site’s employees, consultants or contractors (“ProQR Representatives”) and individuals who will be participating in the clinical trials who have a need to access the Device in connection with use of the Device for the clinical
trials and who have been advised of ProQR’s obligations with respect to such Device. ProQR shall not allow its Affiliates, its Permitted Sublicensees or ProQR Representatives to keep or disburse the Device to any other person or other location,
unless ProQR first obtains PARI’s written permission. ProQR shall be liable for the use of the Device by its Affiliates, its Permitted Sublicensees or ProQR Representatives in violation of this Section 8.8(b).

Permitted Sublicensees or ProQR Representatives or patients participating in the clinical trials under ProQR’s control, at the clinical trial sites listed in the applicable purchase order for such Devices accepted by PARI. 

(d) ProQR, its Affiliates and Permitted Sublicensees shall conduct the clinical trials pursuant to a written protocol (the
“Study Protocol”). ProQR shall provide a synopsis of the Study Protocol to PARI prior to the commencement of the applicable clinical trials. Following the completion of the clinical trial studies, ProQR shall retrieve the Devices at
ProQR’s expense and the Devices shall be stored or destroyed and discarded by ProQR which destruction and disposal is confirmed to PARI by ProQR in writing. 

(e) ProQR shall not, and shall cause its Affiliates and Permitted Sublicensees not to, subject to analysis or have subjected to
analysis the Devices and/or components constituting Devices received from PARI for the purpose of reverse engineering or in a manner that would reveal material composition or internal design or operation of such sample and/or component or its method
of manufacture. ProQR shall be responsible for any breaches of this Section 8.8 by any of its Affiliates and/or Permitted Sublicensees. 
  

	9.	INDEMNIFICATION 

 9.1 Indemnification by PARI. PARI shall indemnify, defend and
hold harmless ProQR and its Affiliates and each of their respective employees, officers, directors and agents from and against any and all third party (including a Permitted Sublicensee) Claims, liability, loss, damage, cost and expense (including
reasonable attorneys’ fees) resulting from or in connection with (i) the material breach by PARI of any representation, warranty or covenant contained in this Agreement; (ii) any product liability Claim by a third party directly
arising from the design or function of the Device, except to the extent attributable to ProQR’s, its Affiliates’ or Permitted Sublicensees’ breach of this Agreement or the Supply Agreement; or (iii) Claim of infringement or

Know-How or other intellectual property rights of any third party by PARI or its Affiliates or the Device or uses and Exploitation thereof to the extent such Claim relates to the Device or the
Licensed Intellectual Property in the Field; provided, however, that such indemnification right shall not apply to any Claims, liability, loss, damage, cost and expense (a) to the extent directly attributable to the negligence, reckless
misconduct, or intentional misconduct of a party seeking indemnification under this Section 9.1, or (b) for which ProQR is obligated to indemnify PARI under Section 9.2(i) through (iv) (Indemnification by ProQR).

 9.2 Indemnification by ProQR. ProQR shall indemnify, defend and hold harmless PARI and its Affiliates and each of their respective
employees, officers, directors and agents from and against any and all third party Claims, liability, loss, damage, cost and expense (including reasonable attorneys’ fees) resulting from or in connection with (i) the material breach by
ProQR, its Affiliates and/or Permitted Sublicensees of any representation, warranty or covenant contained in this Agreement; (ii) Claim of infringement or misappropriation of the patent rights, trade secrets, Know-How or other intellectual
property rights of any third party by ProQR or its Affiliates or the Drug Product or use thereof to the extent such Claim relates to the Drug Product; (iii) the Exploitation of the Device by ProQR, its Affiliates or Permitted Sublicensees; or

attributable to the negligence, reckless misconduct, or intentional misconduct of a party seeking indemnification under this Section 9.2, or (b) for which PARI is obligated to indemnify ProQR under Section 9.1(i) through
(iii). 
 9.3 Indemnification Procedures. Subject to the provisions of Section 5.2.5, promptly after receipt by a
Party seeking indemnification under this Section 9 (an “Indemnitee”) of notice of any pending or threatened claim against it (an “Action”), such Indemnitee shall give written notice to the Party from
whom the Indemnitee is entitled to seek indemnification pursuant to this Section 9 (the “Indemnifying Party”) of the commencement thereof; provided that the failure so to notify the Indemnifying Party shall not relieve
it of any liability that it may have to any Indemnitee hereunder, except to the extent the Indemnifying Party demonstrates that it is materially prejudiced thereby. Any Action that is subject to indemnification under this Section 9 shall
be brought against an Indemnitee and it shall give written notice to the Indemnifying Party of the commencement thereof, the Indemnifying Party shall assume the defense thereof with counsel reasonably satisfactory to such Indemnitee and, the
Indemnifying Party shall not be liable to such Indemnitee under this Section 9 for any fees of other counsel or any other expenses, in each case subsequently incurred by such Indemnitee in connection with the defense thereof. No
compromise or settlement of any Action may be effected by the Indemnifying Party without the Indemnitee’s written consent, which consent shall not be unreasonably withheld or delayed, unless (A) there is no finding or admission of any
violation of Law or any violation of the rights of any person and no effect on any other claims that may be made against the Indemnitee and (B) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party. 

9.4 Insurance. Each of PARI and ProQR shall have and maintain such type and amounts of liability insurance covering its activities
under this Agreement as is normal and customary in the medical device and pharmaceutical industries generally for Parties similarly situated. Each Party shall, upon request of the other Party, provide the requesting Party with extracts or copies, as
permitted under each policy, of the foregoing policies of insurance, along with any amendments and revisions thereto.

pursuant to Section 10.2 and (ii) three (3) months if either PARI terminates this Agreement pursuant to Sections 10.2, 10.3.1 or 10.3.2, or if ProQR terminates this Agreement pursuant to Section 10.4, in each case from the date
of termination, subject to payment of any applicable Royalty obligations, Annual Minimum Royalties and the Compensatory Payment Amount (if and when applicable), and compliance with the provisions of Section 8.8 of this Agreement and the Supply

Section 10.4 (Termination of Agreement by ProQR), (b) PARI pursuant to Section10.3.1 or (c) PARI pursuant to Sections 10.3.2, or 10.3.3, or 10.3.4 unless the applicable Permitted Sublicensee is pursuing
Commercially Reasonable Efforts for the Drug Product for use with the Device in a specific territory pursuant to Section 3.7.1, any Sublicense granted by ProQR hereunder shall survive such termination and automatically convert to a direct
license between PARI and the Permitted Sublicensee provided such Sublicense: (i) received the prior written approval from PARI, (ii) complies with all of the provisions of Section 2.3 and is consistent with all of, and not in conflict
with, any of the terms of this Agreement, (iii) includes financial and payment terms, including Royalty, Annual Minimum Royalties and the Compensatory Payment Amount obligations in this Agreement, (iv) imposes no obligations on PARI more

conform to the provisions of this Agreement, including, but not limited to Section 2.3 and this Section 10.5.6, then in the case of (i) above in this sentence all Sublicenses and in the case of (ii) above in this sentence the
non-conforming

	11.	LIMITATION OF LIABILITY 

 EXCEPT FOR GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, NEITHER PARTY SHALL BE
LIABLE TO THE OTHER PARTY UNDER ANY CIRCUMSTANCES OR ANY LEGAL OR EQUITABLE THEORY, WHETHER IN CONTRACT, STRICT LIABILITY OR OTHERWISE, FOR ANY INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR DAMAGES FOR LOST PROFITS ARISING OUT OF OR RELATED TO
THE LICENSED INTELLECTUAL PROPERTY OR TO THIS AGREEMENT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS AGREEMENT SHALL LIMIT OR EXCLUDE EITHER PARTY’S MANDATORY STATUTORY LIABILITY AND/OR
LIABILITY FOR DEATH OR PERSONAL INJURY SUFFERED BY THE OTHER PARTY CAUSED BY NEGLIGENCE OR FOR FRAUD OR FRAUDULENT MISREPRESENTATION. 
  

	12.	DISPUTE RESOLUTION 

 12.1 Informal Resolution. Subject to
Section 13.6, in the event of any controversy, dispute or claim arising out of, in connection with, or in relation to the interpretation, performance, or alleged breach of this Agreement (the “Dispute”), prior to
instituting any arbitration on account of such Dispute, the Parties shall attempt in good faith to settle such Dispute first by negotiation and consultation between themselves, including referral of such Dispute to the Chief Executive Officer of
ProQR and the President of PARI. In the event said executives are unable to resolve such Dispute or agree upon a mechanism to resolve such Dispute within thirty (30) days of the first written request for dispute resolution under this
Section 12.1, then the Parties shall resolve all such Disputes in accordance with Section 12.2. 
 12.2
Arbitration. If any Dispute has not been resolved by good faith negotiations between the Parties pursuant to Section 12.1 above, then the Parties shall endeavor to settle the Dispute by submitting the matter to binding arbitration
by the International Chamber of Commerce (“ICC”) in Brussels, Belgium. Such arbitration may be conducted under the commercial rules then in effect for the ICC except as provided herein. All such proceedings shall be held in English
and a transcribed record prepared in English. Each Party shall choose one (1) arbitrator within thirty (30) days of receipt of notice of the intent to arbitrate. Such arbitrators shall thereafter choose a third arbitrator within thirty
(30) days of their appointment. If no arbitrator is appointed within the times herein provided or any extension of time which is mutually agreed upon, the ICC shall make such appointment of the first two (2) arbitrators within thirty
(30) days of such failure who shall thereafter pick the third as set forth herein. Each Party in any arbitration proceeding commenced hereunder shall bear such Party’s own costs and expenses (including expert witness and attorneys’
fees) of investigating, preparing and pursuing such arbitration claim. Nothing in this Agreement shall be deemed as preventing either Party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the
Parties and the subject matter of the Dispute as necessary to protect either Party’s name, intellectual property or Confidential Information. If the Dispute involves scientific or technical matters, any arbitrator chosen hereunder shall

have educational training and/or experience sufficient to demonstrate a reasonable level of knowledge in the field of intellectual property in the pharmaceutical and medical device sector. The
award rendered by the arbitrators shall be written, final and non-appealable, and judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. 

12.3 Governing Law. This Agreement shall be governed by the laws of Germany, notwithstanding any conflict of laws provisions. 

 

	13.	MISCELLANEOUS 

 13.1 Unenforceability. Both Parties hereby expressly state that it is the
intention of neither Party to violate any Law. If any of the provisions of this Agreement are held to be void or unenforceable, the validity and force of the remainder of this Agreement shall not be affected thereby and such void or unenforceable
provisions shall be replaced by valid and enforceable provisions which will achieve as far as possible the economic business intentions of the Parties. 

13.2 No Waiver. The failure by either Party to take any action or assert any right hereunder shall in no way be construed to be a
waiver of such right, nor in any way be deemed to affect the validity of this Agreement or any part hereof, or the right of a Party to thereafter enforce each and every provision of this Agreement. 

13.3 Drafting. This Agreement shall not be construed more strictly against one Party than the other because it may have been drafted by
one of the Parties or its counsel, each Party having contributed through its counsel substantially and materially to the negotiation and drafting thereof. 

13.4 Assignment. This Agreement and the Parties’ rights and obligations hereunder shall not be assignable except with the prior
written consent of the other Party, not to be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, either Party shall have the right to assign this Agreement or its rights or obligations under this Agreement to any of its
Affiliates, successors in interest or acquirers of all or substantially all of its assets relating to in case of PARI, any Licensed Intellectual Property or the Device and, in case of ProQR, intellectual property rights, including Know-How, with
respect to the Drug Product, Combination Product, ProQR Technology or ProQR Data; provided that such Affiliate, successor in interest or acquirer (i) in case of ProQR is not a PARI Competitor, and (ii) in any case assumes all of such
Party’s obligations under this Agreement. In addition, the provisions of Section 13.10 shall apply. 
 13.5 Relationship
of the Parties. In making and performing this Agreement, the Parties are acting, and intend to be treated, as independent entities and nothing contained in this Agreement shall be construed or implied to create an agency, partnership, joint
venture, or employer and employee relationship between or among any of the Parties. Except as otherwise provided herein, no Party may make any representation, warranty or commitment, whether express or implied, on behalf of or incur any charges or
expenses for or in the name of any other Party. No Party shall be liable for the act of any other Party unless such act is expressly authorized in writing by such Party. 

13.6 Injunctive Relief. Each of the Parties agrees that if certain material obligations under this Agreement are not performed in
accordance with their specific terms or are otherwise breached, (a) severe and irreparable damage would occur, (b) no adequate remedy at law would exist and (c) damages would be difficult to determine. Each of the Parties agrees that,
in such case, the injured Party or Parties shall be authorized and entitled to obtain from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, as well as any other relief permitted by applicable law, and the
breaching Party shall waive any requirement that such Party or Parties post bond as a condition for obtaining any such relief.

[***] 
 In the event of a merger, consolidation,

is continuing to engage in the business of developing and/or commercializing nebulizers. However, if the merger or acquisition partner had separate lines of business, divisions or operations prior to such change of control, whether or not relating
to nebulizers, the merger or acquisition partner shall be deemed a PARI Competitor only to the extent it is continuing the business of the Original Competitor, and not with respect to any such separate lines of business, divisions or operations.

 In addition, PARI Competitors shall include any subsidiary that is formed by the Original Competitors, but shall not include any subsidiaries acquired by
the Original Competitors if such subsidiaries had separate lines of business, divisions or operations prior to such acquisition, whether or not relating to nebulizers. However, PARI Competitors shall include such subsidiaries to the extent such
subsidiaries continue the lines of business, divisions or operations of the Original Competitors relating to nebulizers.
