will pay to Ionis the milestone payments as set forth in Table 1 below when a milestone event listed in Table 1 is first achieved by a Product targeting DNM2. 

 

	 	8.3.3	 Payment of License Fee and Milestones. Dynacure will satisfy the License Fee payment,
Product Milestones, and the Approval Milestone entitled “[***]” in equity, subject to the Equity Limit provisions in Section 8.2, or through Convertible Bonds if the Equity Limit is reached. All other milestones
will be paid in cash. Notwithstanding the foregoing, Dynacure will make payments in cash under the following circumstances: [***]

likely cause competitive harm to the registrant if publicly disclosed. 

	8.4	 Limitations on Milestone Payments; Exceptions; Notice. 

 

	 	8.4.1	 Each milestone payment set forth in Table 1 above will be paid only once regardless of how many
Products achieve such milestone event and regardless of how many times such milestone event occurs. 

  

	 	8.4.2	 If a particular milestone event is not achieved for a specific Indication because achievement of such
earlier milestone event for the Indication was unnecessary or did not otherwise occur, then upon achievement of a later milestone event for that Indication, the milestone event payment applicable to such earlier milestone event will also be due.
[***] 

  

	 	8.4.3	 In addition, if a particular milestone event is achieved contemporaneously or in connection with another
milestone event, then upon achievement of one such milestone event the other milestone event will also be deemed achieved and the milestone payments for both milestone events are due. [***]. 

 

	 	8.4.4	 Each time a milestone event is achieved under this Article 8, Dynacure will send Ionis a written
notice thereof promptly (but no later than [***]) following the date Dynacure has knowledge of achievement of such milestone event. Thereafter, Ionis will promptly invoice Dynacure for the achievement of any milestone event under this
Article 8 and such milestone payment will be due within [***] after Dynacure’s receipt of such invoice if paid in cash or within [***] after Dynacure’s receipt of such invoice for issuance of Dynacure Securities
or Convertible Bonds. 

  

	8.5	 Royalty Payments by Dynacure to Ionis. 

 

	 	8.5.1	 Full Royalty Rate. [***]

	 	(a)	 Dynacure will pay Ionis royalties on Net Sales of Products arising from named patient and other similar
programs under Applicable Laws, and Dynacure will provide reports and payments to Ionis consistent with this Article 8. No royalties are due on Net Sales of Products arising from

compassionate use and other programs providing for the delivery of Product at no cost. The sales of Products arising from named patient, compassionate use, or other similar programs will not be
considered a First Commercial Sale for purposes of calculating the Full Royalty Rate and Full Royalty Period. 

  

	 	8.5.2	 Application of Royalty Rates. All royalties set forth under
Section 8.5.1 are subject to the provisions of this Section 8.5.2, and are payable as follows: 

  

	 	(a)	 Full Royalty Rate Period. Dynacure’s obligation to pay Ionis the Full Royalty above
with respect to a Product will continue on a country-by-country and Product-by-Product
basis from the date of First Commercial Sale of such Product until the later of the date of expiration of (i) the last Valid Claim within the Licensed Patents covering such Product in the country in which such Product is made, used or sold,
(ii) the data exclusivity period conferred by the applicable Regulatory Authority in such country with respect to such Product (e.g., such as in the case of an orphan drug), and (iii) the tenth (10th) anniversary of the First
Commercial Sale of such Product in such country (such royalty period, the “Full Royalty Period”). For purposes of clarification, and without limitation, any Patent licensed to Dynacure jointly owned under
Section 6.1.1 will be counted as a Licensed Patent covering the Product for determining the Full Royalty Period. 

  

	 	(b)	 Reduced Royalty Period. For each year following the expiration of the Full Royalty Period,
a reduced royalty rate (the “Reduced Royalty Rate”) calculated on a year-by-year basis by multiplying the applicable Full Royalty
Rate by the quotient obtained by dividing (i) the amount of aggregate Annual Net Sales in the previous year, by (ii) the amount of Annual Net Sales in the year having the highest Annual Net Sales during the Full Royalty Period. The term
“Reduced Royalty Period” means on a country-by-country basis, the period commencing upon the expiration of the Full Royalty Period in such
country and ending when the Royalty Quotient has fallen to [***] or less for two consecutive years. 

 [***] 

 

	8.6	 Priority Review Vouchers. If, in connection with a Product, a Regulatory Authority grants
Dynacure credits, reduced fees, priority review or any other incentives including those offered under 21 U.S.C. § 360ff or 21 U.S.C. § 360n-l (each, a “Regulatory Authority
Incentive”) and Dynacure transfers such Regulatory Authority Incentive to a Third Party for consideration, then within [***] after such transfer, Dynacure will pay Ionis the Agreed Percentage (as defined below) of any consideration
Dynacure received from such Third Party transferee for the applicable transfer. If Dynacure uses such a Regulatory Authority Incentive in connection with a non-Product or transfers such Regulatory

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would

Authority Incentive to a Third Party in exchange for non-cash consideration, then within [***] after such use or transfer, Dynacure and Ionis will discuss
and mutually agree on the fair market value of such Regulatory Authority Incentive (including, if applicable, the value of any non-cash consideration received by Dynacure) and Dynacure will pay Ionis the
Agreed Percentage (as defined below) of such fair market value in cash. If Ionis and Dynacure cannot agree on the fair market value of the Regulatory Authority Incentive within [***] after such use or transfer, then the matter will be decided by a
Third Party expert selected by mutual agreement by the Parties whose determination will be final and binding on both Parties. If the Parties cannot agree on a Third Party expert, the dispute resolution provisions of
Section 16.4 will govern. The Agreed Percentage shall be equal to [***] less the percentage of Ionis’ holding in the share capital of Dynacure on a fully diluted basis. 

 

	8.7	 Third Party Payment Obligations, Ionis Minimum Third Party Payments. Except as otherwise
provided in Section 8.8, Dynacure will be responsible for, and will pay all payments to Third Parties that arise from Dynacure’s practice of in-licensed technology necessary to
Commercialize a Product. If Ionis is not receiving a royalty under this Agreement sufficient to cover the Ionis Minimum Third Party Payments, Dynacure will either (i) pay Ionis an amount equal to such Ionis Minimum Third Party Payments, or
(ii) stop using the technology that is the subject of such Ionis Minimum Third Party Payments and provide Ionis written notice thereof. 

  

	8.8	 Additional Core Patents; Royalty Reduction for Third Party Royalties.

  

	 	(a)	 Additional Core Patents. Dynacure will promptly provide Ionis with written notice of any Additional Core
Patents Dynacure believes it has identified and Ionis will have the first right, but not the obligation, to negotiate with and obtain a license from the Third Party that controls such Additional Core Patent. If Ionis obtains such a Third Party
license, Ionis will include such Additional Core Patent in the license granted to Dynacure under Section 6.1.2, it will be considered a Licensed Patent and any financial obligations under such Third Party agreement will be
paid by Ionis (the “Ionis Supported Pass-Through Costs”). 

  

	 	(b)	 Royalty Reduction for Third Party Royalty. If, however, Ionis elects not to obtain such a license to
such Additional Core Patents, Ionis will so notify Dynacure, and Dynacure may obtain such a Third Party license and will be entitled to deduct [***] of payments made to a Third Party to license such Additional Core Patents solely related to
Dynacure’s Commercialization of a Product against the royalties that would otherwise be due under Section 8.5; provided, however, that in no event shall the foregoing deduction reduce the amount of
royalties payable hereunder with respect to such Product in such country in a Calendar Quarter to less than [***] of the royalty amounts that would otherwise be due under Section 8.5 (the

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would

“Maximum Royalty Reduction”), and provided further, that any eligible deduction not taken in a given Calendar Quarter due to the Maximum Royalty Reduction will be
eligible for deduction under this Section 8.8(b) in subsequent Calendar Quarters. 

  

	8.9	 Limitation on Aggregate Reduction of Royalties. Notwithstanding the aggregate royalty
reductions under Section 8.5.2(b) and Section 8.8(b), in no event will the royalties payable to Ionis in any given Calendar Quarter be reduced to an amount less than the Ionis Minimum Third Party
Payments. 

  

	8.10	 Reports and Payments. All payments due under Section 8.5 will be
paid within [***] after the close of each [***] beginning with the First Commercial Sale of a Product. Each payment will be accompanied by a report summarizing Net Sales of Products during the relevant [***] and the calculation of royalties due
thereon, including country and the exchange rate used. If no royalties are payable in respect of a given [***], Dynacure will submit a written royalty report to Ionis so indicating together with an explanation as to why no such royalties are
payable. In addition, beginning with the [***] in which the First Commercial Sale for a Product is made and for each [***] thereafter, within [***] following the end of each such [***], Dynacure will provide Ionis a preliminary, non-binding report estimating the total projected Net Sales of Products and the royalties payable to Ionis for such [***]. 

  

	8.11	 Invoices. Unless otherwise specified hereunder, Ionis will invoice Dynacure within [***]
after each Calendar Quarter for the approved services provided by Ionis in the previous Calendar Quarter. Ionis will include on the invoice its good faith estimate of the Ionis FTE cost for the requested services and the amount of Out-Of-Pocket Expenses incurred by Ionis. Dynacure shall make payments within [***] after receipt of the applicable invoice by Dynacure. 

 

	8.12	 Mode of Payment. Unless otherwise indicated, all payments under this Agreement will be
(i) payable in full in U.S. dollars, regardless of the country(ies) in which sales are made, (ii) made by wire transfer of immediately available funds to an account designated by Ionis in writing, and
(iii) non-creditable, irrevocable and non-refundable. Whenever for the purposes of calculating the royalties payable under this Agreement conversion from any
foreign currency will be required, all amounts will first be calculated in the currency of sale and then converted into United States dollars by applying the monthly average rate of exchange calculated by using the foreign exchange rates published
in Bloomberg during the applicable month starting two Business Days before the beginning of such month and ending two Business Days before the end of such month or any other exchange rate methodology in accordance with GAAP and consistently applied
across all its products by Dynacure or its Sublicensees, as applicable in reporting its Net Sales. 

  

	8.13	 Records Retention. Commencing with the First Commercial Sale of a Product, Dynacure will
keep, and will require its Affiliates and Sublicensees to keep (all in accordance with 

  
 17 

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would

GAAP, consistently applied), complete and accurate records pertaining to Net Sales and any other payment due pursuant to this Article 8 for a period of [***] Calendar
Years after the year in which such Net Sales and any other payment due pursuant to this Article 8, and in sufficient detail to permit Ionis to confirm the accuracy of the Net Sales paid by Dynacure hereunder.

  

	8.14	 Audits of Royalty Reports. Ionis will have the right to have an independent certified
public accounting firm of internationally recognized standing, reasonably acceptable to Dynacure, have access during normal business hours, and upon reasonable prior written notice, to Dynacure’s records as may be reasonably necessary to verify
the accuracy of Net Sales and any other payment due pursuant to this Article 8, as applicable, for any Calendar Quarter or Calendar Year within the preceding [***]; provided, however, that Ionis will not
have the right to conduct more than one such audit in any Calendar Year. The accounting firm will disclose to Ionis only whether the reported Net Sales and any other payments due pursuant to this Article 8 are correct and
details of any discrepancies. Ionis will bear the cost of such audit unless the audit reveals an underreporting of more than [***] of amounts payable to Ionis over an applicable Calendar Year, in which case Dynacure will bear the cost of the audit.
If, based on the results of such audit, additional payments are owed by Dynacure under this Agreement; Dynacure will make such additional payments, with interest as set forth in Section 8.17, within [***] after the date on
which such accounting firm’s written report is delivered to Dynacure. Ionis will treat the financial information subject to review under this Section 8.14 in accordance with the confidentiality provisions of
Article 14. 

  

	8.15	 Taxes. 

 

	 	8.15.1	 Taxes on Income. Each Party will be solely responsible for the payment of all taxes
imposed on its share of income arising directly or indirectly from the activities of the Parties under this Agreement. 

  

	 	8.15.2	 Withholding Tax. The Parties agree to cooperate with one another and use reasonable
efforts to lawfully avoid or reduce tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Dynacure to Ionis under this Agreement. To the extent Dynacure is required to deduct and withhold
taxes, interest or penalties on any payment, Dynacure will pay the amounts of such taxes to the proper governmental authority for the account of Ionis and remit the net amount to Ionis in a timely manner. Dynacure will promptly furnish Ionis with
proof of payment of such taxes. If documentation is necessary in order to secure an exemption from, or a reduction in, any withholding taxes, the Parties will provide such documentation to the extent they are entitled to do so.

  

	 	8.15.3	 Tax Cooperation. Ionis will provide Dynacure with any and all tax forms that may be
reasonably necessary in order for Dynacure to lawfully not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. 

  
 18 

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would
likely cause competitive harm to the registrant if publicly disclosed. 

	 	
Following Dynacure’s timely receipt of such tax forms from Ionis, Dynacure will not withhold tax or will withhold tax at a reduced rate under an applicable bilateral income tax treaty, if
appropriate under the applicable laws. Ionis will provide any such tax forms to Dynacure upon request and in advance of the due date. Each Party will provide the other with reasonable assistance to determine if any taxes are applicable to payments
under this Agreement and to enable the recovery, as permitted by applicable law, of withholding taxes resulting from payments made under this Agreement, such recovery to be for the benefit of the Party who would have been entitled to receive the
money but for the application of withholding tax under this Section 8.15. 

  

	 	8.15.4	 The provisions of this Section 8.15 are to be read in conjunction with the
provisions of Section 16.1 below. 

  

	8.16	 Blocked Currency. In each country where the local currency is blocked and cannot be
removed from the country, royalties accrued in that country will be paid to Ionis in the country in local currency by deposit in a local bank designated by Ionis, unless the Parties otherwise agree. 

 

	8.17	 Interest. If Dynacure fails to make any payment due to Ionis under this Agreement, by the
deadline specified in this Article 8, interest will accrue on a daily basis at the greater of an annual rate equal to [***] above the then-applicable prime commercial lending rate of Citibank, N.A. San Francisco, California, or at the maximum
rate permitted by Applicable Law, whichever is lower. 

  

	8.18	 Sublicense or Corporate Sale. In case of a Sublicense or Corporate Sale to a
pharmaceutical or biopharmaceutical company, the Parties will adjust in good faith the above Net Sales calculation and reporting requirements to the practice of the pharmaceutical or biopharmaceutical company, except Ionis will require a
preliminary, non-binding report following each [***] estimating the total projected Net Sales of Products and the royalties payable to Ionis for such [***]. 

ARTICLE 9. 
 INTELLECTUAL
PROPERTY 
  

	9.1	 Collaboration Technology. Each Party will promptly disclose to the other Party in writing,
any discovery, invention or creation made in the performance of activities under the Agreement (“Collaboration Know-How”). Inventorship of any Patent Rights that claim or cover
Collaboration Know-How (“Collaboration Patents” and together with the Collaboration Know-How, the “Collaboration
Technology”) will be determined in accordance with United States patent laws and ownership will follow inventorship. Subject to any rights or licenses expressly granted under this Agreement, neither Party will have any obligation to
account to the other for profits with respect to, or to obtain any consent of the other Party to license or exploit its rights in Collaboration Technology.

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would

	9.2	 Prosecution of Patents. 

 

	 	9.2.1	 Prior to License Fee Payment. 

 

	 	(a)	 Patents Owned or Controlled by a Party. Prior to License Fee Payment by Dynacure, each
Party will have the right, at its cost and expense and at its discretion, to obtain, prosecute, maintain, and enforce throughout the world any Patents owned or Controlled by such Party, including with respect to Ionis, the Ionis Core Technology
Patents. Ionis will consider in good faith any comments or instructions Dynacure timely provides Ionis related to the prosecution and maintenance of the Product-Specific Patents. 

 

	 	(b)	 Jointly Owned Collaboration Patents. Prior to License Fee Payment by Dynacure, the Parties
will determine which Party will be responsible for the prosecution and maintenance of each jointly owned Collaboration Patent (such Party, the “Prosecuting Party”). In the absence of an agreement, the Prosecuting Party shall
be Dynacure. The Prosecuting Party will control and be responsible for all aspects of the prosecution and maintenance of such jointly owned Collaboration Patents. The Prosecuting Party will consider in good faith any comments or instructions the
other Party timely provides the Prosecuting Party related to the prosecution and maintenance of such jointly owned Collaboration Patents. Unless the Parties otherwise agree, [***]. 

 

	 	9.2.2	 After License Fee Payment. Upon payment of the License Fee by Dynacure and subject to
Section 9.2.4, Dynacure, either directly or through its Affiliates and Sublicensees, will obtain, prosecute, and maintain throughout the world all Product-Specific Patents and jointly owned Collaboration Patents, [***].
Dynacure, or its outside counsel, will provide Ionis with an update of the filing, prosecution and maintenance status for each such Patent on a periodic basis and will reasonably consult with and cooperate with Ionis with respect to the preparation,
filing, prosecution, and maintenance of such Patents, including providing Ionis with drafts of material filings in sufficient time to allow Ionis’ review and comment before such filings are due. Dynacure, or its outside counsel, will provide to
Ionis copies of any material papers relating to the filing, prosecution, and maintenance of such Patents promptly upon their being filed or received. Dynacure may cease prosecuting or maintaining particular applications or patents within such
Patents in selected jurisdictions, if Dynacure determines that it is not commercially reasonable to continue such efforts (in which case the terms of Section 9.2.4 will apply). As soon as practicable following
Dynacure’s exercise of the Option, Ionis will deliver the applicable subject patent files with respect to any such Patents to Dynacure and will execute such documents and perform such acts as may be reasonably necessary for Dynacure to take
control of such patent prosecution and maintenance. 

  
 20 

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would
likely cause competitive harm to the registrant if publicly disclosed. 

	 	9.2.3	 Notice of Disputes. Each Party will notify the other Party within a reasonable period of
time if any action, suit, claim, dispute, or proceeding concerning the Product-Specific Patents licensed hereunder or a Product has been initiated, which, if determined adversely to a Party, would have a material adverse effect on the licenses
granted by Ionis to Dynacure under this Agreement, or that would have a material adverse effect on or would materially impair either Party’s rights under this Agreement. Any information communicated pursuant to this
Section 9.2.3 will be treated as Confidential Information subject to the terms of Article 14. 

  

	 	9.2.4	 Discontinued Patents. If, under Section 9.2.2, Dynacure, its
Affiliates and Sublicensees elect to not pursue or continue the filing, prosecution, or maintenance of any particular applications or patents, or subject matter included in the Product-Specific Patents, in any jurisdiction, Dynacure will give as
much advance written notice as reasonably practicable (but in no event less than [***] or, in the case of an applicable impending deadline, [***] prior to such deadline) to Ionis of any decision not to pursue or continue the preparation, filing,
prosecution and maintenance of such Product-Specific Patent or subject matter included in such Product-Specific Patent (a “Discontinued Patent”). In such case, Ionis may elect to continue preparation, filing,
prosecution, or maintenance of the Discontinued Patent in the select jurisdiction [***]. In the event of such a Discontinued Patent in a Major Market, (i) Dynacure’s exclusive license under Section 6.1 with
respect to such Discontinued Patent in such jurisdiction will automatically convert into a non-exclusive license, and (ii) Ionis and its Affiliates will be relieved of the restrictive covenant under
Section 5.1.2(a) with respect to such Discontinued Patent in such jurisdiction, with the financial terms set forth in Article 8 remaining intact and unaffected. Dynacure will execute such documents
and perform such acts as may be reasonably necessary for Ionis to continue prosecution or maintenance of the applicable Discontinued Patent. 

  

	 	9.2.5	 Cooperation. Each Party will cooperate reasonably in the preparation, filing, prosecution,
maintenance, and defense of the Product-Specific Patents [***]. Such cooperation includes (a) promptly executing all papers and instruments and requiring employees to execute such papers and instruments as reasonable and appropriate so as to
enable such other Party, to file, prosecute, and maintain such Patents in any country; and (b) promptly informing such other Party of matters that may affect the preparation, filing, prosecution, or maintenance of any such Patents.

  

	9.3	 Enforcement of Patents. 

 

	 	9.3.1	 Rights and Procedures. If Ionis or Dynacure determines that any Patent licensed hereunder
is being infringed by a Third Party’s activities and that such infringement could affect the exercise by the Parties of their respective rights and obligations or reduce the benefits anticipated by the Parties under this Agreement, it will
promptly notify the other Party in writing. Except for the Product-Specific Patents, which 

  
 21 

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would
likely cause competitive harm to the registrant if publicly disclosed. 

	 	
are discussed below, the Party controlling the Patent(s) which are allegedly being infringed will have the sole right, but not the obligation, to remove such infringement, including with respect
to Ionis, such infringement of the Ionis Core Technology Patents. Notwithstanding the foregoing, if at the time of such infringement the only Patent Right covering the Product in such country is an Ionis Core Technology Patent, Dynacure may request
that Ionis enforce such Patent Right in such country and, if Ionis does not enforce such Patent Right, then such Patent Right will no longer be royalty-bearing under Section 8.5 in such country. 

 

	 	9.3.2	 Product-Specific Patents. With respect to the Product-Specific Patents, Dynacure will have
the first right, but not the obligation, [***], to remove such infringement. If Ionis requests that Dynacure take action to remove infringement of a Product-Specific Patent, and Dynacure believes it is not commercially appropriate to take such
actions, the Parties will meet and discuss in good faith such circumstances and seek to reach agreement on what appropriate steps to take to cause such infringement to end in a commercially appropriate manner. If Dynacure fails to take steps to
remove any such infringement within [***] following notice of such infringement and a written request from Ionis to take action to remove such infringement, or earlier notifies Ionis in writing of its intent not to take such steps, Ionis will have
the right to do so [***] and Dynacure will have the right, [***], to be represented in any such action. 

  

	 	9.3.3	 Cooperation. The Party not enforcing the applicable Patent will provide reasonable
assistance to the other Party (at such other Party’s expense), including providing access to relevant documents and other evidence, making its employees available at reasonable business hours, and joining the action as a named party to the
extent necessary to allow the enforcing Party to bring or maintain the action or establish damages. If any Third Party asserts in writing or in any legal proceeding that any of the Ionis Patent Rights are unenforceable based on any term or condition
of this Agreement, the Parties shall amend this Agreement as may reasonably be required to affect the original intent of the Parties, including preserving the enforceability of such Ionis Patent Rights. 

 

	 	9.3.4	 Recovery. Any damages or other monetary awards recovered with respect to any action
contemplated by this Section 9.3 will be shared as follows: 

  

	 	(a)	 the amount of such recovery will first be applied to the Parties’ reasonable out-of-pocket costs incurred in connection with such proceeding (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses); then

  

	 	(b)	 any remaining proceeds will be [***].

	11.3	 Procedure. If an Ionis Indemnitee or Dynacure Indemnitee seeks indemnification, such Ionis
Indemnitee or Dynacure Indemnitee will inform the indemnifying Party, in writing, of a Claim as soon as reasonably practicable after such Ionis Indemnitee or Dynacure Indemnitee receives notice of such Claim (it being understood and agreed, however,
that any failure by an Ionis Indemnitee or Dynacure Indemnitee to give such a timely notice will not relieve the indemnifying Party of its indemnification obligations under this Agreement, except to the extent that the indemnifying Party is actually
prejudiced as a result of such failure to timely give notice) and permit the indemnifying Party to assume direction and control of the defense of the Claim (including the sole right to settle it at the sole discretion of the indemnifying Party;
provided that, such settlement or compromise does not admit any fault or negligence on the part of the Ionis Indemnitee or Dynacure Indemnitee, as applicable, or impose any obligation on, or otherwise materially adversely affect, the

not be liable for any legal expenses of other counsel subsequently incurred by such Ionis Indemnitee or Dynacure Indemnitee in connection with the defense thereof unless (i) the indemnifying
Party has agreed to pay such fees and expenses, (ii) the indemnifying Party will have failed to employ counsel reasonably satisfactory to the Ionis Indemnitee or Dynacure Indemnitee, as applicable, in a timely manner, or (iii) the Ionis

of any Product hereunder, Dynacure will procure and maintain until at least [***] after Dynacure’s cessation of Commercialization a product liability insurance policy providing coverage of the greater of (i) [***] per claim and annual aggregate
or (ii) in such amount and with such scope as is, at the Initiation of the First Commercial Sale of any Product, considered sufficient in the industry for a prudent biotechnology company, having regard to the particular Products being

	 	12.2.1	 Termination for Material Breach. If either Party believes that the other is in material
breach of this Agreement then the non-breaching Party may deliver notice of such breach to the other Party. The allegedly breaching Party will have [***] to cure such breach (except to the extent such breach
involves the failure to make a payment when due, which breach must be cured [***] following such notice); provided that, in the case of a breach other than a breach involving the failure to make a payment when due, if the breaching Party uses

Efforts to cure such breach within the [***] cure period but requires additional time to cure such breach, such [***] cure period shall be extended until the earlier of [***] following the notice
of breach or such time as the breaching Party is no longer using Commercially Reasonable Efforts to cure such breach. If the Party receiving notice of breach fails to cure such breach within the [***] period, as applicable, the non-breaching Party may (x) declare a breach hereunder and terminate this Agreement upon written notice, or (y) elect to not terminate this Agreement, and in such event the
non-breaching Party will retain its right to continue this Agreement while simultaneously pursuing remedies permitted at law or in equity (including contract damage remedies), subject to the terms, conditions,
and limits imposed by this Agreement. 

  

	 	12.2.2	 Termination by Ionis for Dynacure’s Failure to Meet Obligations. Ionis will have the
right to terminate this Agreement and the licenses granted under Section 6.1, if Dynacure is in breach of the following obligations; provided, however, that the Agreement and such licenses will not so
terminate unless: (i) Dynacure is given 90 days prior written notice by Ionis of Ionis’ intent to terminate, stating the reasons and justification for such termination, and (ii) Dynacure, or its Affiliate or Sublicensee, has not cured
such breach during the 90 day period, as such period may be extended, following such notice: 

  

	 	(a)	 Minimum Funding Obligation in accordance with Section 3.3.1,

  

	 	(b)	 the funding of the NHP Study in accordance with Section 3.3.2, or

  

	 	(c)	 achievement of a Performance Milestone in accordance with Section 7.5.

  

	 	12.2.3	 Termination by Dynacure. This Agreement may be terminated by Dynacure, without cause, upon
90 days written notice to Ionis. For the avoidance of doubt, upon any such termination under this Section 12.2.3, Dynacure and its Affiliates and Sublicensees will stop selling all Products and all Products will revert back
to Ionis in accordance with Article 13. 

  

	 	12.2.4	 Termination for Insolvency. Either Party may terminate this Agreement if, at any time, the
other Party files in any court or agency pursuant to any statute or regulation of any state or country a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Party or
of substantially all of its assets; or if the other Party proposes a written agreement of composition or extension of substantially all of its debts; or if the other Party will be served with an involuntary petition against it, filed in any
insolvency proceeding, and such petition will not be dismissed within 90 days after the filing thereof; or if the other Party will propose or be a party to any dissolution or liquidation; or if the other Party will make an assignment of
substantially all of its assets for the benefit of creditors. Notwithstanding any further rights under

Applicable Law, upon written request of the other Party, the Party filing for bankruptcy, insolvency or a similar proceeding as set forth in this Section 12.2.4 will
promptly provide to such other Party all information and documents necessary to prosecute, maintain and enjoy its rights under the terms of this Agreement. 

  

	 	12.2.5	 Termination for Failure to Identify a Development Compound. If, despite using Commercially
Reasonable Efforts, Ionis is unable to identify a Development Candidate in accordance with Section 3.4.1, either Party may terminate this Agreement by providing the other Party with 30 days written notice of termination.
Upon termination under this Section 12.2.5: 

  

	 	(a)	 Dynacure will have no further rights in Products; and 

 

	 	(b)	 Each Party shall provide to the other all data and information resulting from its drug discovery
activities pursuant to the Research Plan; 

  

	 	(c)	 Dynacure and Ionis shall be entitled to exercise any rights in jointly owned Collaboration Technology
available under applicable law including, without limitation, the right to use and exploit such jointly owned Collaboration Technology for any purpose and to license, sell, assign or otherwise transfer its interest in such jointly owned
Collaboration Technology to any third party without notice or compensation to the other Party. 

  

	12.3	 Consequences of Expiration or Termination of this Agreement. 

 

	 	12.3.1	 Return of Information and Materials. Upon termination of this Agreement by either Party
pursuant to this Article 12, each Party will return to the other Party (or destroy, as directed by such Party) all data, files, records and other materials containing or comprising such Party’s Confidential Information. Notwithstanding
the foregoing, each Party will be permitted to retain one copy of such data, files, records, and other materials for archival purposes and for regulatory compliance. 

 

	 	12.3.2	 Sublicense Survival. If this Agreement terminates for any reason, then, at Dynacure’s
request, any Sublicensee will, from the effective date of such termination, become a direct licensee of Ionis with respect to the rights sublicensed to the Sublicensee by Dynacure; so long as (i) Dynacure has provided Ionis a complete copy of
the applicable Sublicense and paid Ionis any Sublicense Revenue associated therewith, (ii) such Sublicensee is not in breach of its Sublicense, (iii) such Sublicensee continues to comply with all of the terms of the Sublicense, including
the obligations of this Agreement imposed on Sublicensee by the Sublicense, and (iv) such Sublicensee agrees to continue to pay directly to Ionis the portion of such Sublicensee’s payments under the Sublicense due to Ionis under this
Agreement. Dynacure agrees that it will confirm clause (i) of the foregoing in writing at the request and for the benefit of Ionis and if requested, the Sublicensee.

	12.4	 Accrued Rights: Surviving Obligations. 

 

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

  

	 	12.4.2	 Survival. Appendix 1 (to the extent definitions are embodied in the following
listed Articles and Sections); Article 11 (Indemnification; Insurance), Article 12 (Term; Termination), Article 13 (Ionis Reversion Right), Article 14
(Confidentiality) and Article 16 (Miscellaneous), Section 8.6 (Priority Review Vouchers), Section 8.10 (Reports and Payments), Section 8.12 (Mode
of Payment), Section 8.13 (Records Retention), Section 8.14 (Audits of Royalty Reports), Section 8.15 (Taxes) and Section 10.4 (Disclaimer of
Warranty) of this Agreement will survive expiration or termination of this Agreement for any reason. 

  

	 	12.4.3	 Rights in Bankruptcy. All rights and licenses granted under this Agreement, including,
without limitation, the licenses granted to Dynacure under Article 6 and the licenses granted to Ionis under Article 13, are, for purposes of Section 365(n) of the U.S. Bankruptcy Code (i.e., Title 11 of the
U.S. Code) or analogous provisions of Applicable Law outside the United States, licenses of rights to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code or analogous provisions of Applicable Law outside
the United States. The Parties agree that each Party, as licensee of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code or any other provisions of Applicable Law
outside the United States that provide similar protection for ‘intellectual property.’ The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against a Party under the U.S. Bankruptcy Code or
analogous provisions of Applicable Law outside the United States, the Party that is not subject to such proceeding will be entitled to a complete duplicate of (or complete access to, as appropriate) such intellectual property and all embodiments of
such intellectual property, which, if not already in the non-subject Party’s possession, will be promptly delivered to it upon the non-subject Party’s written
request therefor. Any agreements supplemental hereto will be deemed to be “agreements supplementary to” this Agreement for purposes of Section 365(n) of the U.S. Bankruptcy Code.

 ARTICLE 13. 

IONIS REVERSION RIGHT 
  

	13.1	 Ionis Reversion Rights; Reverse Royalty Payments to Dynacure for Discontinued Products. If
the Agreement (a) expires under Section 4.1.2(c), (b) is terminated by Ionis under Section 12.2.1, Section 12.2.2 or Section 12.2.4, or
(c) is terminated by Dynacure under Section 12.2.3, all rights and licenses granted by Ionis to Dynacure hereunder will be terminated. Ionis may elect to continue to Develop and Commercialize any Products that are the
subject of such termination (collectively, “Discontinued Product(s)”) by written notice to Dynacure (an “Election Notice”) that Ionis is exercising its rights under this
Section 13.1. in which case, Dynacure: 

  

	 	(a)	 hereby grants to Ionis an exclusive license to all of Dynacure’s rights in Product-Specific Patents
Controlled by Dynacure (including Dynacure’s interest in any joint Product-Specific Patents) and hereby assigns any trademarks Controlled by Dynacure related to the Discontinued Products; 

 

	 	(b)	 hereby grants to Ionis, a worldwide, sublicensable,
non-exclusive license or sublicense, as the case may be, to all Patent Rights, data and know-how Controlled by Dynacure as of the date of the expiration or termination
necessary to Research, Develop, make, have made, use, sell, offer for sale, have sold, import and otherwise Commercialize Discontinued Products (“Dynacure Background IP”); and 

 

	 	(c)	 will transfer to Ionis, for Ionis’ exclusive use with respect to the Development and
Commercialization of the Discontinued Products, copies of any data, results, regulatory information and files in the possession of Dynacure that are necessary for Ionis to Research, Develop, make, have made, use, sell, offer for sale, have sold,
import and otherwise Commercialize Discontinued Products and take such action as necessary to transfer regulatory documents in Ionis’ name and control of regulatory proceedings to Ionis. 

 

	13.2	 If Ionis or any of its Affiliates or sublicensees Commercializes any Discontinued Product that, but for
the license granted to Ionis under Section 13.1(b), would infringe Dynacure’s Background IP, Ionis will pay all payments that Dynacure is obliged to make to a Third Party in connection with such Dynacure Background IP
for the continued Development, manufacture or Commercialization of the Discontinued Product as well as a [***] royalty payment to Dynacure on Annual worldwide Net Sales on a
country-by-country basis and Discontinued Product-by-Discontinued Product during the Full
Royalty Period as applied mutatis mutandis to a Valid Claim within the Dynacure Background IP or any Patent Rights exclusively licensed from Dynacure to Ionis (including Dynacure’s interest in any joint Product-Specific Patents).

  
 31 

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would
likely cause competitive harm to the registrant if publicly disclosed. 

	13.3	 For the avoidance of doubt, Ionis’ rights under this Article 13 are in addition to any other
rights and remedies available to Ionis under this Agreement and applicable law, including Ionis’ termination rights under Article 12. 

 

	13.4	 Applicable Royalty Provisions. In addition to this Article 13, the definition of
Net Sales in Appendix 1 and the other provisions contained in Article 8 governing payment of royalties from Dynacure to Ionis will govern the payment of royalties from Ionis to Dynacure under this
Article 13, mutatis mutandis. 

 ARTICLE 14. 

CONFIDENTIALITY 
  

	14.1	 Disclosure and Use Restriction. Each Party agrees that, for so long as this Agreement is
in effect and for a period of [***] years thereafter, a Party (the “Receiving Party”) receiving Confidential Information of the other Party (the “Disclosing Party”) will (i) maintain in confidence
such Confidential Information, (ii) not disclose such Confidential Information except to the Receiving Party’s employees having a need-to-know such
Confidential Information, (iii) not disclose such Confidential Information to any Third Party without the prior written consent of the Disclosing Party, except for disclosures expressly permitted by this Agreement, and (iv) not use such
Confidential Information for any purpose except those expressly permitted by this Agreement. 

  

	14.2	 Authorized Disclosure. To the extent that it is reasonably necessary or appropriate to
fulfill its obligations or exercise its rights under this Agreement, a Party may disclose Confidential Information belonging to the other Party in the following instances: 

 

	 	(a)	 filing or prosecuting patent applications in accordance with this Agreement; 

 

	 	(b)	 communicating with Regulatory Authorities as necessary for the Development or Commercialization of a
Product in a country, in accordance with this Agreement and as required in connection with any filing, application or request for Approval; provided, however, that reasonable measures will be taken to assure confidential treatment of
such information; 

  

	 	(c)	 prosecuting or defending litigation; 

 

	 	(d)	 complying with applicable laws and regulations (including the rules and regulations of the Securities
and Exchange Commission or any national securities exchange, and compliance with tax laws and regulations) and with judicial process, if (i) in the reasonable opinion of the Receiving Party’s counsel, such disclosure is necessary for such
compliance and (ii) such disclosure is made in accordance with Section 14.3 or Section 14.4 as applicable; 

  
 32 

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would
likely cause competitive harm to the registrant if publicly disclosed. 

	 	(e)	 disclosure, in connection with the performance of this Agreement and solely on a need-to-know basis, to Affiliates, potential or actual collaborators (including potential Sublicensees), potential or actual investment bankers, investors, lenders, or
acquirers, or employees, independent contractors or agents, each of whom prior to disclosure must be bound by written obligations of confidentiality and non-use no less restrictive than the obligations set
forth in this Article 14; provided, however, that the Receiving Party will remain responsible for any failure by any Person who receives Confidential Information pursuant to this Article 14 to treat
such Confidential Information as required under this Article 14; and 

  

	 	(f)	 in the case of Dynacure, its Affiliates and Sublicensees, use and disclosure of Ionis Know-How in the ordinary course of the exercise of the rights and licenses granted to Dynacure hereunder. 

If Confidential Information is disclosed in accordance with this Section 14.2, such disclosure will not cause any
such information to cease to be Confidential Information except to the extent that such permitted disclosure results in a public disclosure of such information (other than by breach of this Agreement). Where reasonably possible and subject to
Section 14.3 and Section 14.4, the Receiving Party will notify the Disclosing Party of the Receiving Party’s intent to make such disclosure pursuant to clauses (a) through (d) of this
Section 14.2 prior to making such disclosure to allow the Disclosing Party adequate time to take whatever action it may deem appropriate to protect the confidentiality of the information. 

 

	14.3	 Required Disclosure. A Receiving Party may disclose Confidential Information pursuant to
interrogatories, requests for information or documents, subpoena, civil investigative demand issued by a court or governmental agency or as otherwise required by Law; provided, however, that, unless legally prohibited
from doing so, the Receiving Party will notify the Disclosing Party promptly upon receipt thereof, giving (where practicable) the Disclosing Party sufficient advance notice to permit it to oppose, limit or seek confidential treatment for such
disclosure, and to file for patent protection if relevant; and provided, further, that the Receiving Party will furnish only that portion of the Confidential Information which it is advised by counsel is legally required
whether or not a protective order or other similar order is obtained by the Disclosing Party. 

  

	14.4	 Securities Filings. If either Party proposes to file with the Securities and Exchange
Commission or the securities regulators of any state or other jurisdiction a registration statement, periodic report, or any other disclosure document which describes or refers to this Agreement under the Securities Act of 1933, as amended, the
Securities Exchange Act, of 1934, as amended, or any other applicable securities Law, the Party will notify the other Party of such intention and will provide such other Party with a copy of relevant portions of the proposed filing not less than
five Business Days prior to such filing, and will seek to obtain confidential treatment of any information concerning the Agreement that such other 

  
 33 

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would
likely cause competitive harm to the registrant if publicly disclosed. 

	 	
Party requests be kept confidential (except to the extent advised by counsel that confidential treatment is not available for such information), and will only disclose Confidential Information
which it is advised by counsel is legally required to be disclosed. No such notice will be required under this Section 14.4 if the substance of the description of or reference to this Agreement contained in the proposed
filing has been included in any previous filing made by either Party hereunder or otherwise approved by the other Party. 

  

	14.5	 Injunctive Relief. The Parties understand and agree that remedies at law may be inadequate
to protect against any breach of any of the provisions of this Article 14 by either Party. Accordingly, each Party is entitled to seek injunctive relief by a court of competent jurisdiction against any action that constitutes a breach of this
Article 14. 

 ARTICLE 15. 

PRESS RELEASES AND PUBLICATIONS 
  

	15.1	 Press Releases; Public Disclosure. Upon execution of this Agreement, the Parties will
issue either a joint press release or separate press releases announcing the existence of this Agreement in a form and substance agreed to in writing by the Parties. Each Party agrees not to issue any other press release or other public statement
disclosing other information relating to this Agreement or the transactions contemplated hereby without the prior written consent of the other Party, which consent will not be unreasonably withheld or delayed; provided,
however, that each Party may make disclosures permitted by, and in accordance with, Article 14. Each Party agrees to provide to the other Party a copy of any public announcement regarding this Agreement or the transactions
contemplated hereby as soon as reasonably practicable prior to its scheduled release. Except under extraordinary circumstances, each Party will provide the other with an advance copy of any such announcement at least five Business Days prior to its
scheduled release. Each Party will have the right to expeditiously review and recommend changes to any such announcement and, except as otherwise permitted by Article 14, the Party whose announcement has been reviewed will
remove any information the reviewing Party reasonably deems to be inappropriate for disclosure. The contents of any announcement or similar publicity which has been reviewed and approved by the reviewing Party can be
re-released by either Party without a requirement for re-approval. 

  

	15.2	 Dynacure will promptly notify (and provide as much advance notice as possible to) Ionis of any material event
related to the Clinical Study results or any Approval of a Product so that the Parties may analyze the need to or desirability of publicly disclosing or reporting such event. Notwithstanding Section 15.1 above, any press
release or other similar public communication (other than communications with regulatory authorities governed under Section 7.5) by Dynacure related to a Product’s efficacy or safety data and/or results, will be
submitted to Ionis for review at least [***] Business Days in advance (if reasonably practicable under the circumstances and if not reasonably practicable, as far in advance as possible) of such proposed public disclosure, and Dynacure will give
good faith consideration to any comments provided by Ionis as a result of such review. 

  
 34 

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would
likely cause competitive harm to the registrant if publicly disclosed. 

	15.3	 Scientific or Clinical Presentations. Regarding any proposed scientific or clinical
publications or public presentations related to summaries of results from any of the activities under this Agreement generated by Ionis or Dynacure, the Parties acknowledge that scientific lead time is a key element of the value under this Agreement
and further agree to use Commercially Reasonable Efforts to control public scientific disclosures of the results of the activities under this Agreement to prevent any potential adverse effect of any premature public disclosure of such results. The
Parties will agree to a publication plan whereby each Party will first submit to the other Party an advanced draft of all such publications or presentations, whether they are to be presented orally or in written form, at least [***] prior to
submission for publication. Each Party will review such proposed publication in order to avoid the unauthorized disclosure of a Party’s Confidential Information and to preserve the patentability of Collaboration
Know-How arising under this Agreement. If, during such [***] period, the other Party informs such Party that its proposed publication contains Confidential Information of the other Party that should be
removed, then such Party will delete such Confidential Information from its proposed publication. If, during such [***] period, the other Party informs such Party that additional time is needed to permit the timely preparation and first filing of
patent application(s), then such Party will delay such proposed publication for [***] from the date the other Party informed such Party of the need. Notwithstanding the foregoing, if the Parties mutually agree that public disclosure of such proposed
publication could reasonably be expected to have a material adverse effect on the ability to develop an ASO as a therapeutic candidate, the Parties will delay publication until a patent application covering such ASO is filed. 

 

	15.4	 Acknowledgment. Dynacure will acknowledge in any press release, public presentation or
publication regarding the Product that the Product is under license from Ionis and Ionis’ stock ticker symbol (e.g., Nasdaq: IONS). Ionis may include any Product in Ionis’ drug pipeline. 

ARTICLE 16. 

MISCELLANEOUS 
  

	16.1	 Assignment and Successors. Neither this Agreement nor any obligation of a Party hereunder
may be assigned by either Party without the consent of the other, which will not be unreasonably withheld, delayed or conditioned, except that each Party may assign this Agreement and the rights, obligations and interests of such Party, in whole or
in part, without the other Party’s consent, to any of its Affiliates, to any purchaser of all or substantially all of its business or assets to which this Agreement relates or to any successor corporation resulting from any merger,
consolidation, share exchange or other similar transaction; provided, if Dynacure or any of its Affiliates or Sublicensees transfers or assigns this Agreement or a Sublicense to one of its Affiliates that is incorporated in a jurisdiction
that does not have a Bilateral Income Tax Treaty with the United States or in a jurisdiction where a Bilateral Income Tax Treaty requires withholding taxes on any payment described in this Agreement, then Dynacure (or such Affiliate or Sublicensee),
will increase (i.e., “gross up”) any payment due Ionis under Article 8 for the Incremental

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would
likely cause competitive harm to the registrant if publicly disclosed. 

 
Tax Cost such that Ionis receives the amount Ionis would have otherwise received under Article 8 but for such transfer or assignment. In addition, Ionis may assign or
transfer its rights to receive payments under this Agreement (but, subject to any right that Dynacure may have under applicable law), without Dynacure’s consent, to an Affiliate or to a Third Party in connection with a payment factoring
transaction. Any purported assignment or transfer made in contravention of this Section 16.1 will be null and void. 

The “Incremental Tax Cost” shall equal the amount of foreign withholding taxes withheld under
Article 8 in each year in which such tax is paid and Ionis cannot obtain a corresponding cash benefit from the foreign tax credit under IRC Sec 901 (or successor provision), grossed up by the applicable withholding tax rate
based on a payment to a United States Person (unless the actual applicable treaty is lower, in which case the lower withholding tax rate shall be used) to equal the pre withholding tax payment. 

To the extent Ionis benefits from a foreign tax credit related to any Incremental Tax Cost, Ionis will refund to Dynacure an amount equal to
100% of the foreign tax credit utilized. Notwithstanding the foregoing, if the increase in the withholding tax is in any way a result of the transfer or assignment by Ionis of any intellectual property or a portion of the rights under this license
outside of the United States, Dynacure will only be obligated to pay Ionis such gross up to the extent such transfer or assignment by Ionis did not cause such increase in the withholding tax. 

 

	16.2	 Severability. If any provision of this Agreement is held to be illegal, invalid or
unenforceable by a court of competent jurisdiction, such adjudication will not affect or impair, in whole or in part, the validity, enforceability, or legality of any remaining portions of this Agreement. All remaining portions will remain in full
force and effect as if the original Agreement had been executed without the invalidated, unenforceable or illegal part. The Parties agree to use good faith, reasonable efforts to replace the illegal, invalid or unenforceable provision with a legal,
valid and enforceable provision that achieves similar economic and non-economic effects as the severed provision. 

  

	16.3	 Governing Law. This Agreement will be governed by and construed and enforced in accordance
with the laws of the State of New York, USA without reference to any rules of conflicts of laws. 

  

	16.4	 Dispute Resolution. 

 

	 	16.4.1	 Resolution by Senior Representatives. The Parties will seek to settle amicably any and all
disputes, controversies or claims arising out of or in connection with This Agreement. Any such dispute between the Parties will be promptly presented to the Chief Executive Officer of Dynacure and the Chief Operating Officer of Ionis (the
“Senior Representatives”), or their respective designees, for resolution. Such Senior Representatives, or their respective designees, will meet in-person or by teleconference as soon as
reasonably possible thereafter, and use their good faith

efforts to agree upon the resolution of the dispute, controversy or claim. If a dispute between the Parties arising out of or relating to the validity or interpretation of, compliance with,
breach or alleged breach of or termination of this Agreement cannot be resolved within [***] of presentation to the Senior Representatives, or their respective designees, for resolution, either Party may refer such dispute to binding arbitration to
be conducted as set forth below in this Section 16.4. For clarification, any dispute relating to the validity or scope of any Patent or related to the Research or Development matters decided by the JSC will not be subject
to arbitration. Following a Sublicense or Corporate Sale to a pharmaceutical or biopharmaceutical company, Dynacure shall have the final say with respect to Research or Development matters decided by the JSC, other than matters that are reasonably
likely to have a material adverse effect on patient safety or Ionis’ technology, if they cannot be settled by the Senior Representatives within [***] of presentation to the Senior Representatives, or their respective designees, for resolution.

  

	16.4.2	 Arbitration. 

 

	 	(a)	 If the Parties fail to resolve the Dispute through Escalation, and a Party desires to pursue resolution
of the Dispute, the Dispute will be submitted by either Party for resolution by arbitration request (the “Arbitration Request”) under the Rules of Arbitration of the International Chamber of Commerce (the
“Rules”) by one (1) arbitrator appointed in accordance with the said Rules (each such arbitration, an “Arbitration”). [***] Each Arbitration will be conducted in English and all foreign
language documents shall be submitted in the original language and, if so requested by any arbitrator or Party, shall also be accompanied by a translation into English. The place of arbitration shall be New York, New York. 

 

	 	(b)	 Except to the limited extent necessary to comply with applicable Law, legal process, or a court order or
to enforce a final settlement agreement or secure enforcement or vacatur of the arbitrators’ award, the Parties agree that the existence, terms and content of any Arbitration, all information and documents disclosed in any Arbitration or
evidencing any arbitration results, award, judgment or settlement, or the performance thereof, and any allegations, statements and admissions made or positions taken by either Party in any Arbitration shall be treated and maintained in confidence
and are not intended to be used or disclosed for any other purpose or in any other forum. 

  

	 	(c)	 All costs and expenses of any Arbitration, including reasonable attorneys’ fees and expenses and
the administrative and arbitrator fees and expenses, shall be [***].

	 	(d)	 EXCEPT IN THE CASE OF COURT ACTIONS PERMITTED BY SECTION 16.5, AND FOR CLAIMS NOT SUBJECT TO
ARBITRATION AS SET FORTH IN SECTION 16.5, EACH PARTY HERETO WAIVES: (1) ITS RIGHT TO TRIAL OF ANY ISSUE BY JURY, (2) WITH THE EXCEPTION OF RELIEF MANDATED BY STATUTE, ANY CLAIM TO PUNITIVE, EXEMPLARY, MULTIPLIED, INDIRECT,
CONSEQUENTIAL OR LOST PROFITS/REVENUES DAMAGES, AND (3) ANY CLAIM FOR ATTORNEY FEES, COSTS AND PREJUDGMENT INTEREST. 

  

	16.5	 Injunctive Relief; Court Actions. Notwithstanding anything to the contrary in this
Agreement, each Party will be entitled to seek from any court of competent jurisdiction, in addition to any other remedy it may have at law or in equity, injunctive or other equitable relief in the event of an actual or threatened breach of this
Agreement by the other Party, without the posting of any bond or other security, and such an action may be filed and maintained notwithstanding any ongoing discussions between the Parties or any ongoing arbitration proceeding. The Parties agree that
in the event of a threatened or actual material breach of this Agreement injunctive or equitable relief would be an appropriate remedy. In addition, either Party may bring an action in any court of competent jurisdiction to resolve disputes
pertaining to the validity, construction, scope, enforceability, infringement or other violations of Patent Rights or other intellectual property rights, and no such claim will be subject to arbitration pursuant to
Section 16.4.2. 

  

	16.6	 Force Majeure. No Party will be held responsible to the other Party nor be deemed to be in
default under, or in breach of any provision of, this Agreement for failure or delay in performing any obligation of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or
delaying. For purposes of this Agreement, force majeure means a cause beyond the reasonable control of a Party, which may include acts of God, war, terrorism, civil commotion, fire, flood, earthquake, tornado, tsunami, explosion or storm; pandemic;
epidemic and failure of public utilities or common carriers. In such event the Party so failing or delaying will immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party
giving such notice will be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled for up to a maximum of [***], after which time the Parties will negotiate in good faith
any permanent or transitory modifications of the terms of this Agreement that may be necessary to arrive at an equitable solution, unless the Party giving such notice has set out a reasonable timeframe and plan to resolve the effects of such force
majeure and executes such plan within such timeframe. To the extent possible, each Party will use reasonable efforts to minimize the duration of any force majeure. 

 

	16.7	 Notices. Any notice or request required or permitted to be given under or in connection
with this Agreement will be deemed to have been sufficiently given if in writing and personally delivered or sent by certified mail (return receipt requested), facsimile

	4.2	 The Parties agree to add the following paragraph at the end of Section 8.3.3:

 “If a milestone event is not achieved because Development activities transpired such that achievement of such
earlier milestone event was unnecessary or did not otherwise occur, then upon achievement of a later milestone event, the payment applicable to such earlier milestone event will also be due. [***] 

 

	4.3	 The Parties agree to replace Section 8.3.4 in its entirety with the following:

 “8.3.4. Corporate Sale. [***]. In addition, if the Corporate Sale occurs
before [***] in a specific Indication, then the milestone payments set forth in Table I payable after such Corporate Sale for such Indication will be multiplied by a factor [***] only. 

[***] 
 It is understood
between the Parties that once Dynacure has [***] in a certain Indication, then milestones specific to that Indication will no longer be subject to the factor [***], but that milestones specific to other Indications for which [***] will continue to
be subject to the factor [***]. It is understood between the Parties that all milestones already paid by Dynacure prior to the Corporate Sale will be considered as fully paid and will not be subject to the above provision of
Section 8.3.4.” 
  

	4.4	 The Parties agree to add a Section 8.3.5 as follows: 

“8.3.5 Sublicense Revenue. In the event that Dynacure enters into a Sublicense with any Third Party,
Ionis shall receive the following consideration from Dynacure: 
  

	 	(a)	 Where Dynacure enters into any such Sublicense [***] in a certain Indication, [***] of all Sublicense
Revenue as and when received by Dynacure for such Sublicense for such Indication; and

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would
likely cause competitive harm to the registrant if publicly disclosed. 

	 	(b)	 Where Dynacure grants any such Sublicense after [***] in a certain Indication, [***] of all Sublicense
Revenue as and when received by Dynacure for such Sublicense for such Indication. 

 After entering into an
exclusive Sublicense with respect to a certain Indication and given country, Dynacure shall not owe any further payments, royalties or milestones with respect to the exploitation of a Product in such exclusive Indication and country other than those
set forth in this Section 8.3.5 and the other payments under Section 8.3 and 8.5 shall no longer apply to such exclusive Indication and country, provided that Sublicense Revenue received by
Ionis based on the percentage of such Sublicensee’s Annual Net Sales received by Dynacure under such exclusive Sublicense shall not be lower than [***]of Sublicensee’s Annual Net Sales for such Indication on a country by country and
Product by Product basis. 
 For the avoidance of doubt, whether Ionis is receiving [***] of Sublicense Revenue under
Section 8.3.5(a) or [***] of Sublicense Revenue under Section 8.3.5(b), the percentage of Sublicense Revenue received by Ionis based on Sublicensee’s Annual Net Sales shall in no event be less
than [***] of Sublicensee’s Annual Net Sales for a certain Indication on a country by country and Product by Product basis.” 
  

	4.5	 The Parties agree to replace the first paragraph of Section 8.5.1 with the
following: 

 “8.5.1 Full royalty rate. As
partial consideration for the rights granted to Dynacure hereunder, subject to the provisions of this Section 8.5.1 and Section 8.5.2,
Dynacure will pay to Ionis royalties on Annual worldwide Net Sales of Products sold by Dynacure or its Affiliates, on a country-by-country and Product-by-Product basis in each case in the amounts as follows in Table 2 below (the “Full Royalty Rate”)”. 

The remainder of this article is unchanged. 

ARTICLE 5 – PATENTS 
  

	5.1	 The Parties wish to add the following patent and all related patent applications in Appendix 5
listing Ionis Product-Specific Patents: [

request”.

 Article 2 – TERM 

The present Agreement shall take effect upon the EFFECTIVE DATE, and absent early termination pursuant to the terms in Article 15 herein. 

LICENSEE’s payment obligation hereunder shall terminate at the latest of: 

 

	 	(i)	 with respect to any given country the expiry or invalidation of the last PATENT covering the manufacturing, use
or commercialization of the LICENSED PRODUCTS in such country; or

approval by CONECTUS, of the name of any proposed SUBLICENSEE (the “Notice”). Such consent shall not unreasonably be delayed more than [***] days (which period may be
reduced if the negotiation does not allow for such a [***] days’ notice) and cannot be denied unless CONECTUS can reasonably demonstrate that said potential SUBLICENSEE would violate or otherwise contravene the laws and regulations applicable
to ESTABLISHMENTS’ status, activities and/or missions. Such approval shall be deemed granted if CONECTUS does not respond within [***] days of the Notice (each, a “Deemed Approval Circumstance”). Furthermore, LICENSEE

CONECTUS to audit the SUBLICENSEE’s financial records and accounts consistent with Section 7.7.

applicable obligations assumed by LICENSEE under the present Agreement. 

  

	3.5	 CONECTUS shall use reasonable efforts to substitute the ESTABLISHMENTS for itself in the rights and obligations
under this Agreement so that the LICENSE is granted directly by the ESTABLISHMENTS. 

 Article 4 – ASSIGNMENT, TRANSFER AND CHANGE
IN CONTROL 
  

	4.1	 The present Agreement is non-transferable and non-assignable, subject to rights possibly granted by LICENSEE to SUBLICENSEES in accordance with the Agreement and to the provisions hereunder. 

 

	4.2	 LICENSEE may assign or transfer to one or more of its AFFILIATES (including an entity that becomes an AFFILIATE
pursuant to a CHANGE IN CONTROL of LICENSEE) all or part of the rights and obligations assumed by LICENSEE under the present Agreement, subject to, expect in case of Deemed Approval Circumstances, prior written consent from notification to CONECTUS
at least [***] days (which period may be reduced if the negotiation does not allow for such a [***] days’ notice) prior to executing any such agreement so that CONECTUS may object to the assignment or transfer to the AFFILIATES.

 Any such objection shall be communicated in writing to LICENSEE within [***] days of the date of the CONECTUS
notification from LICENSEE (or within any shorter period reasonably stated in the notification, if the negotiation does not allow for such a [***] days’ notice). For the avoidance of doubt, it is hereby understood that CONECTUS may only

refuse its approval if it can reasonably demonstrate that said AFFILIATES would violate or otherwise contravene the laws and regulations applicable to ESTABLISHMENTS’ status, activities
and/or missions. 

 For the avoidance of doubt, no consent is required in Deemed Approval Circumstances. 

Subject to the above, LICENSEE may assign or transfer to an AFFILIATE all or part of the rights and obligations assumed by LICENSEE under the
present Agreement. 
 In such case of assignment or transfer of the present Agreement described in the first paragraph of the present Article
4.2, LICENSEE shall be solely responsible towards CONECTUS for the correct execution by said AFFILIATES of all obligations assumed by LICENSEE under the present Agreement. 
  

	4.3	 LICENSEE shall notify CONECTUS, of any CHANGE IN CONTROL of LICENSEE which modifies the intuitu personae
nature of the present Agreement, other than in case of Deemed Approval Circumstances. 

 The Agreement may be terminated if
CONECTUS can reasonably demonstrate in writing, within thirty (30) days from CONECTUS’ receipt of the LICENSEE’s notification in writing of a CHANGE IN CONTROL, that the CHANGE IN CONTROL of LICENSEE would materially violate or
otherwise contravene the status, activities and/or missions of any of the ESTABLISHMENTS included in the laws and regulations applicable to the ESTABLISHMENTS’ status, activities and/or missions. For the avoidance of doubt, the foregoing shall
not apply in Deemed Approval Circumstances. 
  

	4.4	 It is hereby understood that the assignee of the present Agreement shall be subject to the same obligations as
those of LICENSEE in the present Agreement, unless the new parties should reach another mutual agreement. 

 Without
limiting the foregoing, in any case of assignment of this Agreement pursuant to this Agreement as described herein, an amendment to the present Agreement shall be established between CONECTUS and the assignee as soon as reasonably practicable. 

Article 5 – EXPLOITATION

and/or the physical person concerned, as the case may be. 

 For the sole purpose of identifying the origin of the license,

CONECTUS or the ESTABLISHMENTS guarantee in any way the LICENSED PRODUCTS. 
 LICENSEE agrees to impose upon its AFFILIATES and its possible
distributors the same obligations. 
  

	5.3	 LICENSEE and its AFFILIATES shall commercialize the LICENSED PRODUCTS under their own trademarks or under THIRD
PARTY trademarks for which they have obtained rights. CONECTUS or the ESTABLISHMENTS shall have no rights over any such trademarks.

confidentiality agreement acceptable to LICENSEE, but only to the extent necessary to verify the amount of the royalties payable under the present Agreement to CONECTUS. Any given period can only be audited once and no later than within [***] months
following the beginning of such period. If any inspection leads to the discovery of a greater than [***] understatement in reporting of royalties or other payments due under the present Agreement, LICENSEE shall pay the actual costs and expense of
such inspection, and the underpayment. The outstanding amount due shall bear interest according to the rules applicable to French public research Establishments (which, as of the date or the last day of that period until that amount is paid in full

	7.8	 The payments properly due by LICENSEE to CONECTUS under the present Agreement shall in no event be refundable

 Furthermore, in the event of expiration or termination of the present Agreement, LICENSEE shall pay all and
any sums due to CONECTUS at the expiration date or the date of termination to CONECTUS.

doubt AFFILIATES, consultants, service providers and advisors) as if their activities in relation to the confidential information were carried out by the receiving PARTY itself. 

Notwithstanding any other provision of the present Agreement, CONFIDENTIAL INFORMATION shall not include any item of information which:

	9.1	 At the effective date of the Agreement, LICENSEE or, at the election of LICENSEE, the SUBLICENSEE will manage
the prosecution of the PATENTS. Any industrial property decision that must be made to have the PATENTS issued or maintain their validity shall be made by LICENSEE, after consultation with CONECTUS in advance of each such decision. LICENSEE shall
inform the patent attorney in charge of the PATENTS or the service company in charge of collecting the annuities of its decision. If LICENSEE elects not to file, prosecute or maintain, in any country, a patent application or patent claiming a
particular invention in the PATENTS, then such patent application or patent shall be no longer sublicensed to LICENSEE and LICENSEE shall give CONECTUS the opportunity to take over prosecution or maintenance in a reasonable time frame.

 LICENSEE shall instruct its external patent attorneys to provide CONECTUS with copies of all documents, correspondence
and materials relating to the prosecution by LICENSEE

	9.5	 Should LICENSEE [***], LICENSEE shall promptly inform CONECTUS, in writing, by registered letter with
acknowledgment of receipt, at least [***] before the intellectual property prosecuting deadline of that element of the PATENTS, that it will no longer support that element of the PATENTS. In such event, LICENSEE shall no longer be entitled to

the TERRITORY declined by LICENSEE. CONECTUS and/or the ESTABLISHMENTS shall be entitled to sign research or exploitation agreements with THIRD PARTIES under that element of those PATENTS but limited solely to those countries of the TERRITORY for
which LICENSEE [***]. It is hereby understood that [***]. 

  

	9.6	 In the event LICENSEE [***], LICENSEE agrees to provide all necessary signatures and documents to CONECTUS for
the continued prosecution of the PATENTS, in accordance with the provisions of Article 9.4 herein.

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would

	10.2	 Except as expressly set forth in the present Agreement, CONECTUS MAKES NO OTHER WARRANTIES, EXPRESS OR IMPLIED
OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, OR THAT THE MANUFACTURE, USE, IMPORT OR SALE OF LICENSED PRODUCTS SHALL NOT INFRINGE ANY PATENT OR OTHER RIGHTS OF A THIRD PARTY. 

 

	10.3	 The risks and perils possible associated with the execution of the present Agreement and in particular with the
PATENTS are the sole responsibility of LICENSEE who hereby accepts them. 

  

	10.4	 In consequence, should any of the PATENTS be rejected, annulled or declared dependant to an anterior dominant
patent or should the LICENSED PRODUCTS be declared in infringement in a final legal decision as result of the use of the PATENTS, CONECTUS shall not be liable to reimburse any sums paid by LICENSEE or, unless otherwise provided herein, to reduce the
sums due until said final decision, or to pay damages to LICENSEE in retribution for prejudice caused for such rejection, cancellation, dependence or infringement. 

 

	10.5	 LICENSEE shall not call upon CONECTUS in warranty in the event of damage, or prejudice of any nature caused by
the LICENSED PRODUCTS. LICENSEE shall be solely responsible to clients and/or any other THIRD PARTIES for the quality and performance of the LICENSED PRODUCTS.

invalid, dependent or in infringement, LICENSEE shall not call CONECTUS in warranty and shall not claim any damages, reimbursement or reduction of sums paid or due (unless otherwise provided herein) to CONECTUS at the moment of the final legal
decision. 

 Article 11 – LIMITATION OF LIABILITY 

IN NO EVENT SHALL EITHER PARTY OR ITS AFFILIATES (AS APPLICABLE) BE LIABLE HEREUNDER TO THE OTHER PARTY, ITS AFFILIATES OR ANY OTHER PERSON OR
ENTITY FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL, EXEMPLARY OR OTHER INDIRECT DAMAGES (INCLUDING, BUT NOT LIMITED TO, LOSS OF PROFITS OR LOSS OF USE DAMAGES) ARISING FROM MANUFACTURE, USE OR SALE OF LICENSED PRODUCTS, EVEN IF SUCH PARTY HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR LOSSES.

 Article 12 – INFRINGEMENT 

 

	12.1	 CONECTUS and LICENSEE shall inform each other in writing promptly with respect of any THIRD PARTY infringement

	12.2	 Should there be a THIRD PARTY infringement of the PATENTS, CONECTUS and/or the ESTABLISHMENTS may at their sole
expense undertake legal action against the infringing party with the understanding that [***]. 

 The foregoing shall not
prevent LICENSEE from taking action against any THIRD PARTY infringement of the PATENTS in its name or in the name of CONECTUS [***] for seeking compensation for prejudice which it has incurred. Any expenses, losses, indemnification or damages which
may be awarded by court decision for said prejudice will [***]. If an action is taken in the name of CONECTUS, CONECTUS shall timely provide any required power of attorney and LICENSEE shall indemnify CONECTUS of any Third Party’s claim against
CONECTUS in relation with this action. 
  

	12.3	 Should the ESTABLISHMENTS and CONECTUS decide not to undertake a legal action against THIRD PARTY infringement
of the PATENTS, and if LICENSEE wishes to undertake such legal action, CONECTUS shall use reasonable efforts to cause the ESTABLISHMENTS to give LICENSEE the power of attorney to undertake a legal action in the name of the ESTABLISHMENTS. If the
ESTABLISHMENTS choose not to give such power of attorney to LICENSEE, then CONECTUS shall cause the ESTABLISHMENTS to work with the THIRD PARTY infringer to reach an acceptable solution to remedy such THIRD PARTY infringing activity (e.g. in the way
of a license, agreement to cease and desist, etc.) and as long as a solution acceptable to LICENSEE is not reached, the PATENTS shall not longer be subject to royalty pursuant to this Agreement. 

 

	12.4	 In the case where LICENSEE undertakes legal action against THIRD PARTY infringement of the PATENTS, [***], and
CONECTUS agrees to cooperate fully with LICENSEE as reasonably requested in such legal action, including, without limitation, providing any documents necessary or helpful for such legal action. 

The stipulations set out above are applicable subject to the legal imperative provisions applicable in the country where the infringement
occurs. 
  

	12.5	 Should any infringement suit be brought against LICENSEE and/or its AFFILIATES and/or its SUBLICENSEES with
respect to the exploitation of LICENSED PRODUCTS due to the use of the PATENTS or other rights granted to LICENSEE in the present Agreement, CONECTUS shall cooperate fully with LICENSEE in LICENSEE’s defense, including without limitation
providing LICENSEE with the documents which may be required for its defence.

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would

 Should LICENSEE be found guilty for said infringement, CONECTUS shall not be called in
warranty by LICENSEE or be liable to indemnify, reimburse or reduce any of the sums due by LICENSEE at the moment of the final legal decision, except as otherwise set forth in Article 13 herein. 

 

	12.6	 It is hereby declared that the conditions of the present Agreement shall not apply to infringement of the
PATENTS outside the FIELD and the TERRITORY which is the sole responsibility of the ESTABLISHMENTS, CONECTUS or any THIRD PARTY appointed by them. 

  

	12.7	 The PARTIES agree to provide any documents and elements and reasonable cooperation to the other PARTY, which
may be necessary for the above-mentioned action to the other PARTY. 

 Article 13 –
INDEMNIFICATION 
  

	13.1	 LICENSEE shall indemnify, defend and hold harmless CONECTUS, and their officers, faculty members, shareholders,
employees and agents (each a “CONECTUS Indemnified Party”) from and against any liability, damage, loss, or expense (including reasonable attorneys’ fees and expenses of litigation) incurred by or imposed upon any and
all CONECTUS Indemnified Parties in connection with any claims, suits, actions, demands or judgments arising out of any THIRD PARTY claim concerning any LICENSED PRODUCT made, used or sold by or for LICENSEE pursuant to any right or license granted
to LICENSEE under the present Agreement, except to the extent that such claim, suit, action, demand, or judgment arises out of or results from the gross fault, recklessness or wilful misconduct of CONECTUS or its AFFILIATE(S). 

 

	13.2	 CONECTUS shall indemnify, defend and hold harmless LICENSEE, its AFFILIATES, and its/their officers, directors,
employees and agents (each a “LICENSEE Indemnified Party”) from and against any liability, damage, loss, or expense (including reasonable attorneys’ fees and expenses of litigation) incurred by or imposed upon any and all
LICENSEE Indemnified Parties in connection with any claims, suits, actions, demands or judgments arising out of any THIRD PARTY claim concerning any breach of any warranty in the present Agreement by CONECTUS, except to the extent that such claim,
suit, action, demand, or judgment arises out of or results from the negligence, recklessness or wilful misconduct of the LICENSEE or its AFFILIATE(S). 

  

	13.3	 The Indemnified PARTIES agree to provide the Indemnifying PARTY with prompt written notice of any claim, suit,
action, demand, or judgment for which indemnification is sought under the present Agreement. The Indemnifying PARTY agrees, at its own expense, to provide attorneys reasonably acceptable to the Indemnified PARTY to defend against any such claim. The
Indemnified PARTY shall cooperate fully with the Indemnifying PARTY in such defense and will permit the Indemnifying PARTY to conduct and control such defense and the disposition of such claim, suit, or action (including all decisions relative to
litigation, appeal, and settlement); provided, however, that any Indemnified PARTY shall have the right to retain its own counsel, at the expense of the Indemnifying PARTY, if 

  
 20 

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would

representation of such Indemnified PARTY by the counsel retained by the Indemnifying PARTY would be inappropriate because of actual differences in the interests of such Indemnified PARTY and any
other PARTY represented by such counsel. The Indemnifying PARTY agrees to keep the Indemnified PARTY informed of the progress in the defense and disposition of such claim and to consult with the Indemnified PARTY with regard to any proposed
settlement. 

 Article 14 – APPROVAL OF IONIS AS A SUBLICENSEE 

Pursuant to Section 3.1, CONECTUS hereby approves IONIS as a non-exclusive SUBLICENSEE solely with
respect to the discontinued products for which IONIS has exercised its reversion rights granted under Section 13 of the license agreement signed between IONIS and LICENSEE on even date herewith. Such discontinued products shall be notified to
CONECTUS at the time of the exercise by IONIS of its reversion rights. In the event the present Agreement is terminated other than from circumstances attributable to IONIS, then the sublicense shall become a direct license between CONECTUS and
IONIS. 
 Article 15 – DISMISSAL AND NULLITY 

If in the TERRITORY, an administrative decision or a definitive court decision pronounces the total or partial dismissal and/or the total or
partial nullity of one or several of the PATENTS and/or a restriction of the freedom of exploitation of the PATENTS, except as otherwise allowed herein, LICENSEE shall not claim to CONECTUS any allowance, refunding, reduction of the sums due at when
the administrative or definitive decision occurs. 
 Article 16 – TERMINATION 

 

	16.1	 This Agreement may be terminated by LICENSEE at any time upon sixty (60) days’ prior written notice
to CONECTUS. In addition to the foregoing, this Agreement may be terminated by either one PARTY in the event that the other PARTY fails to perform one or more of the material obligations contained in the Agreement and does not cure such material
breach within six (6) months of the written notice of the other PARTY including a description of the breach and then only if the PARTY at fault has not, within this period, fulfilled its obligations or shown proof of a case of force majeure
that prevented it from fulfilling its obligations. The exercise of such right to termination does not apply if LICENSEE can establish an event not attributable to LICENSEE that reasonably prevented it from fulfilling its obligations. In addition,
the exercise of such right does not exempt the PARTY in default from its obligations hereunder accrued prior to the effective date of termination or the liability of such PARTY for damages incurred as a result of early termination because of breach
of the Agreement. Notwithstanding the foregoing, if LICENSEE is in material breach of the provisions of Article 5, Article 6 and Article 9 and does not cure such material breach within six (6) months of the written notice of CONECTUS including
a description of the breach, and LICENSEE does not provide evidence of an event not attributable to LICENSEE that reasonably prevented it from fulfilling its obligations, then, CONECTUS may either convert the LICENSE into a nonexclusive license, as
its sole remedy.

	16.2	 CONECTUS shall have the right to terminate the present Agreement in case of a judicial recovery or of a
liquidation procedure of the LICENSEE, or in case of voluntary recovery or of a voluntary liquidation procedure subject to the applicable regulations in France;
