 Recitals 

The Max-Planck-Gesellschaft zur Foerderung der Wissenschaften e.V. (hereinafter “MPG”) is a German non-profit scientific research
organisation. At the Max-Planck-Institute for Biophysical Chemistry in Goettingen (“MPI-BC”), a research institute of MPG, Dr. Thomas Tuschl and other scientists of MPI-BC have discovered the sequence and structural features of
single-stranded RNA molecules required to mediate target-specific nucleic acid modifications by RNA interference ([***]). The aforementioned invention was funded by the German government. MPG has filed certain Patent Rights (as later defined herein)
relating thereto. 
 MI is a wholly owned subsidiary of MPG and acts as MPG’s technology transfer agency. MPG has authorized MI to act as its sole
agent for patenting and licensing the Patent Rights, and to sign this Agreement in MI’s own name for the account of MPG. 
 On [***], MI entered into a
co-exclusive license agreement regarding the Patent Rights with each of Isis Pharmaceuticals, Inc., Carlsbad, CA 92008, USA (hereinafter “ISIS”) and Alnylam Pharmaceuticals Inc., Cambridge, MA 02142, USA (hereinafter
“ALNYLAM”, and such agreement the “ALNYLAM Agreement”). 
 On April 12, 2013, the United States Patent and Trademark
Office declared a patent interference (No. 105,928) between the US UMMS Patent (as later defined herein) as junior party, and the US MPG Patent (as later defined herein) as senior party (the “Patent Interference”). As a result of
the Patent Interference, the United States Patent and Trademark Office has determined that the US UMMS Patent had priority over the US MPG Patent. MI and the University of Massachusetts Medical School (“UMMS”), a U.S. public
institution of higher education of the Commonwealth of Massachusetts, have agreed that the US UMMS Patent shall be added to the Patent Rights, and that MI shall be authorized by UMMS to sign license agreements that encompass the US UMMS Patent in
MI’s own name for the account of UMMS. In this respect, UMMS will be a third party beneficiary of this Agreement, and, unless expressly set forth otherwise in this Agreement, UMMS will have no rights against or obligations to WAVE under this
Agreement. 
 On [***] ALNYLAM terminated the ALNYLAM Agreement, and ISIS subsequently declined the offer of MI to become the sole exclusive licensee and
has remained the sole co-exclusive licensee. 
 WAVE desires to obtain from MI the second co-exclusive license under the Patent Rights for the purpose of
developing and commercializing diagnostic and therapeutic products. WAVE (and its permitted successors and assignees) and ISIS (and its permitted successors and assignees) are hereinafter also individually called a “Co-Exclusive
Licensee” and, together the “Co-Exclusive Licensees”. 
 Now, therefore, MI and WAVE hereby agree as follows: 

ARTICLE 1 - DEFINITIONS 
  

	1.1	“Affiliate” 

 shall mean any legal entity (such as a corporation, partnership, or limited
liability company) that is controlled by a Party, is controlling a Party, or is under common control with a Party. For the purposes of this definition, the term “control” means (i) beneficial ownership of at least fifty percent
(50%) of the voting securities of a legal entity with voting securities, or (ii) a fifty percent (50%) or greater interest in the net assets or profits of a legal entity without voting securities, or (iii) possession, directly or
indirectly, of the power to elect or direct the management of a legal entity.

ultimately bad debts. 
 WAVE, its Affiliates and Sublicensees will be treated as having sold their respective Licensed Products for an amount equal to the
fair market value of such Licensed Products, if (i) Licensed Products are used by WAVE, its Affiliates and Sublicensees without charge or provision of invoice, or (ii) Licensed Products are provided to a Third Party by WAVE, its Affiliates
and Sublicensees without charge or provision of invoice and used by such Third Party, except in the cases of Licensed Products used to conduct non-clinical research, product development or clinical trials, reasonable amounts of Licensed Products
used as marketing samples, and Licensed Products provided without charge for compassionate or similar uses. 
 If WAVE, its Affiliates or Sublicensees sell
a Licensed Product in unfinished form (i.e., bulk Active Pharmaceutical Ingredient) to a Third Party for resale, then the gross amount to be included in the calculation of Net Sales arising from such sale shall be the amount invoiced by the
Third Party upon resale, in lieu of the amounts invoiced by WAVE, its Affiliates or Sublicensee when selling the Licensed Product in unfinished form. Otherwise, where WAVE, its Affiliate or Sublicensee sell a Licensed Product in finished form in a
manner and at a price consistent with industry standards for such sales to a Third Party (including a Sales Partner) for 
  

***Confidential Treatment Requested***

 CONFIDENTIAL 

 

 
further resale, the amount to be included in the calculation of Net Sales shall be the amount invoiced by WAVE, its Affiliates or Sublicensees to such Third Party, not the amount invoiced by such
Third Party upon resale. 
 No deductions shall be made for commissions paid to individuals or entities, or for cost of collections. Net Sales shall occur
on the date of invoice for a Licensed Product. In the case of any sale of Licensed Products for non-cash consideration (e.g., devices, services, use rights, equity etc.), Net Sales shall be calculated on the fair market value of the
consideration received. 
 Sales of Licensed Products between WAVE and its Affiliates and/or Sublicensees, or among such Affiliates and Sublicensees, for a
subsequent resale of such Licensed Product to a Third Party, shall not be included in the calculation of Net Sales, but in such cases the Net Sales shall be calculated on the amount invoiced by such Affiliates or Sublicensees to a Third Party upon
resale. 
 In the event that a Licensed Product is sold in a combination product form (with one or more other therapeutically active ingredients (excluding,
without limitation, any formulation, stabilization and delivery components) which are not Licensed Products), which therapeutically active ingredients are also independently marketed during the royalty period in question in the country in question,
then Net Sales, for purposes of determining royalty payments on the combination product, shall be calculated by multiplying the Net Sales of the combination product by the fraction A/(A+B), where A is [***], and B is [***]. In the event that a
Licensed Product is sold in combination with other therapeutically active ingredient(s), and the Licensed Product or one or more other therapeutically active ingredients are not sold separately, Net Sales for the purposes of determining royalty
payments shall be calculated by multiplying the Net Sales of the combination product by the fraction of C/(C+D), where C is [***] and D is the [***] 
  

	1.17	“Patent Rights” 

 shall mean: 

 

	(a)	the issued patents and pending patent applications and provisional patent applications listed on Appendix A, and the resulting patents, 

 

	(b)	any patent applications resulting from the provisional applications listed on Appendix A, and any divisionals, continuations, continuation-in-part applications, and requests for continued examination (and their relevant
international equivalents) of the patent applications listed on Appendix A and of such patent applications that result from the provisional applications listed on Appendix A, and the resulting patents, in each case to the extent the claims are
directed to the subject matter specifically described in the patent applications listed on Appendix A and ultimately claiming priority to the patent applications listed on Appendix A, and 

 

	(c)	any patents resulting from re-issues, re-examinations, or extensions (including supplemental protection certificates) (and their relevant international equivalents) of the patents described in (a) and
(b) above. 

 For the avoidance of doubt, the term “Patent Rights” shall include the US UMMS Patent. 

 

	1.18	“Phase I Clinical Study” 

 shall mean a clinical investigation of a Licensed Product in human
healthy persons or patients designed and conducted to evaluate safety and/or tolerance. 
  

***Confidential Treatment Requested*** 

  
 page 5 of 23

patients to establish efficacy and safety and required to file a NDA application of a Licensed Product with Regulatory Authorities. 
  

	1.21	“Platform License” 

 shall mean a license granted by WAVE to a Third Party, in which multiple
patents (including the Patent Rights granted as a sublicense in accordance with Section 2.2 below, and substantial other patents reasonably necessary or useful for the development and/or commercialization of a Licensed Product that are
Controlled by WAVE and granted to such Third Party as a direct license), are bundled together for use by such Third Party/Sublicensee such that the Third Party/Sublicensee may pursue the research, manufacture, development and commercialization of
Licensed Products using technology covered by one or more of such multiple patents (including the Patent Rights); provided, however, that a license shall not be a “Platform License” if the only patents licensed thereunder are Patent
Rights. 
  

	1.22	“Regulatory Approval” 

 shall mean any and all approvals (including any applicable governmental
price and reimbursement approvals), licenses, registrations or authorizations of any Regulatory Authority necessary for the manufacture, use, storage, import, promotion, marketing, pricing and/or sale of a Licensed Product in a country. 

 

	1.23	“Regulatory Authority” 

 shall mean any federal, national, multinational, state, provincial or
local regulatory agency, department, bureau or other governmental entity with authority over the testing, manufacture, use, storage, import, promotion, marketing, pricing and/or sale of a Licensed Product in a country, including without limitation
the FDA and the EMA. 
  

	1.24	“Sales Partner” 

 shall mean any person or legal entity that is authorized by WAVE (or its
Affiliates or Sublicensees) by any kind of agreement to market, promote, distribute or sell, or otherwise dispose of, Licensed Products to an independent Third Party in a first commercial sale at arm’s length transaction without violating this
Agreement or the Patent Rights. 
 For the purpose of this definition, “Sales Partner” shall not include distributors who purchase Licensed
Products from WAVE (or its Affiliates or Sublicensees) in a first commercial sale at arm’s length transaction for further resale, provided that the relation between WAVE (or its Affiliates or Sublicensees) and such distributor is a pure
seller-buyer relationship, i.e. the agreement between WAVE (or its Affiliates or Sublicensees) and such distributor does not contain any obligation to share costs or revenues, or a reporting obligation or responsibility for sales and/or marketing
efforts in a country. In such event, the gross amount to be included in the calculation of Net Sales shall be the amount invoiced by WAVE (or its Affiliates or Sublicensees) to such distributor, not the amount invoiced by such distributor upon
resale. 
  

	1.25	“Sublicensee” 

 shall mean any Third Party that is granted a sublicense to the Patent Rights in
accordance with Section 2.2. 
  

	1.26	“Sublicense Consideration” 

 shall mean any consideration, whether in cash (including, without
limitation, initial or upfront payments, technology access fees, annual maintenance fees) or in kind (including, without limitation, devices, services, licenses or any other use rights, shares, options, warrants or any

the Patent Rights in the country in question that (i) has not lapsed, and (ii) has not been withdrawn, canceled or disclaimed, or held unenforceable by a tribunal of competent jurisdiction in an unappealed or unappealable decision,
provided, however, that Valid Claim will exclude any such pending claim in an application that has not been granted within 10 years following the earliest priority date of such application. 

ARTICLE 2 - GRANT OF RIGHTS 
 2.1 License Grant

 MI hereby grants to WAVE and its Affiliates a co-exclusive royalty-bearing, worldwide license, with the right to sublicense in accordance with
Section 2.2, under the Patent Rights to research, develop, commercialize, make, have made, use, have used, offer for sale, sell, have sold, import, export, have imported and have exported Licensed Products and Licensed Processes in the Field.

 In order to establish co-exclusivity, and subject to the terms of the last paragraph of this Section 2.1, MI shall not grant, during the Term, more
than in total two co-exclusive licenses to the Patent Rights in the Field. For the avoidance of doubt, in no event will there be more than two (2) co-exclusive licenses to the Patent Rights in the Field in existence at any given time. As of the
Effective Date, the co-exclusive licensors are ISIS and WAVE. 
  

***Confidential Treatment Requested*** 

  
 page 7 of 23 

 CONFIDENTIAL 

 

 In the event that either ISIS or WAVE, as applicable, ceases to be a Co-Exclusive Licensee under this
Agreement (the “Terminated Co-Exclusive Licensee”), MI shall promptly provide the remaining Co-Exclusive Licensee with a written offer of an exclusive license under the Patent Rights in the Field, on substantially the same terms and
conditions (including substantially the same economic terms) (such offer, an “Exclusivity Notice”) previously applicable to the Terminated Co-Exclusive Licensee under this Agreement. The remaining Co-Exclusive Licensee shall have
the right, but not the obligation, for a period not to exceed three (3) months after receipt of an Exclusivity Notice, to execute such exclusive license with MI, after which time, if such exclusive license is not executed, MI will be free to
negotiate one additional co-exclusive license with a Third Party (co-exclusive with the remaining Co-Exclusive Licensee) the material terms and conditions of which are no more favorable to such Third Party as a whole than the terms and conditions
applicable to the remaining Co-Exclusive Licensee under this Agreement; provided, however, that any such co-exclusive license agreement granted to a Third Party will be consistent with this Agreement. 

2.2 Sublicenses 
 (a) WAVE (but not its Affiliates) has
the right to grant sublicenses to the rights granted under Section 2.1 to Third Parties, however only (i) in connection with a Platform License, Drug Discovery Collaboration or Development Collaboration, (ii) to a Sales Partner for
the sale of Licensed Products, or (iii) pursuant to a contract under which WAVE retains substantially all intellectual property arising from the sublicense of the Patent Rights and retains the sole right to commercialize Licensed Products,
including without limitation a contract with a contract manufacturing organization (“CMO”) for the manufacture of Licensed Products solely for WAVE. 

(b) WAVE shall ensure that each sublicense granted under this Agreement, and any subsequent sublicenses granted by any Sublicensee, shall be subject and
subordinate to, and consistent with, the terms and conditions of this Agreement. 
 (c) Within 30 days after the signature of each sublicense granted under
this Agreement, WAVE shall provide MI with a copy of the signed sublicense agreement, subject to reasonable redactions to protect the confidential information of the Sublicensee. 

2.3 Retained Rights; Improvements 
 MPG (specifically the
MPI-BC) and UMMS each retains the right to practice under the Patent Rights for scientific research, teaching, education, non-commercial scientific collaboration (including collaborations with and/or sponsored by industry), provided that such
collaborations will not include the grant of a right to the industry partner to develop or commercialize Licensed Products under the Patent Rights in the Field (i.e., any partnership with industry must focus on research only and may not be
performed in conjunction with the development of a Licensed Product) and scientific publication purposes. 
 If, as a result of MPI-BC’s practice of
the Patent Rights, the MPI-BC makes, within [***] months after the Effective Date, an improvement to the Patent Rights consisting of an invention that directly relates to or is directly based upon the invention embodied in the Patent Rights (the
“Improvement”), such Improvement will be deemed automatically included in the license grant to WAVE under Section 2.1(a) as of the Effective Date for no additional consideration, but only to the extent such Improvement is
necessary to practice the Patent Rights. 
 WAVE acknowledges that the German government retains a royalty-free, non-exclusive, non-transferable license to
practice any government-funded invention claimed in the Patent Rights for governmental purposes, and that UMMS retains the right to grant licenses under the US UMMS Patent to the United States Government in accordance with 35 USC 200-212 or 37 CFR
401 et seq. and applicable governmental implementing regulations.

or otherwise, as to any intellectual property rights, including without limitation patents and patent applications, trademarks, copyrights and know-how of MPG and UMMS other than the Patent Rights. 

2.5 No Additional Support by MPI-BC 
 Neither MI nor MPG
nor MPI-BC nor UMMS shall have any obligation under this Agreement to provide support to WAVE in connection with the development and commercialization of Licensed Products. WAVE may ask MPI-BC at any time during the Term to provide such support.
MPI-BC shall have the right, in its discretion, to enter into a scientific collaboration agreement, and/or MPI-BC employees shall have the right, in their discretion, to enter into a scientific consultancy agreement, provided that the aforementioned
agreements are in compliance with the applicable rules of MPG. Notwithstanding the foregoing, WAVE and MI shall cooperate regarding the prosecution of the Patent Rights, as further specified in Article 6 below.

immediately on the achievement of each respective milestone event (but in no event later than [***] days after such an achievement). 
 Each of the above
milestone payments is due by WAVE to MI for each respective Licensed Product separately, and regardless of whether the milestone event is achieved by WAVE, its Affiliates or Sublicensees. For the avoidance of doubt, each milestone payment is payable
only once per Target irrespective of the number of Licensed Products targeting such Target to achieve such milestone. For purposes of this Section 5.3, the term “Target” means a single gene, as defined in the NCBI Entrez Gene
database, or any successor database thereto, and any naturally occurring variants thereof, or a product of such gene. 
 5.4 Running Royalties 

(a) Royalty Rate 
 During the Term, WAVE shall pay to
MI running royalties on Net Sales of Licensed Products of [***]% ([***]) on a Licensed Product-by-Licensed Product and country-by-country basis. For the avoidance of doubt, in the event ISIS and WAVE are jointly developing and/or commercializing a
Licensed Product, the running royalty set forth in the preceding 
  

***Confidential Treatment Requested*** 

  
 page 11 of 23 

 CONFIDENTIAL 

 

 
sentence shall be due by ISIS and WAVE for each of their respective Net Sales of such Licensed Product separately. For example only, if ISIS and WAVE have a collaboration agreement for the
development and commercialization of a Licensed Product, and ISIS sells the respective Licensed Product under such a collaboration agreement, a royalty of [***]% on the respective Net Sales of ISIS of such Licensed Product will be due from ISIS, and
if WAVE sells the respective Licensed Product under such a collaboration agreement, a separate royalty of [***]% on the respective Net Sales of WAVE will be due from WAVE, and vice versa. 

(b) Royalty Stacking; Minimum Royalty Floor 
 If WAVE is a
party to a license agreement with any Third Party, which license is employed in connection with the Patent Rights for the manufacture, use and/or sale of a Licensed Product (i.e. if Licensed Products sold by WAVE require WAVE to pay royalties to a
Third Party), the royalty rate set forth in Section 5.4 (a) above will be reduced, on a country-by-country and Licensed Product-by-Licensed Product basis, from the date running royalties have to be actually paid to such Third Party, by up
to [***]% of any running royalty owed to such Third Party for the manufacture, use or sale of such a Licensed Product; provided, however, in no event shall the royalty rate due to MI according to Section 5.4 (a) be reduced by the
application of this Section 5.4 (b) to less than a minimum royalty rate of [***]% ([***]). 
 5.5 Sublicense Revenues 

(a) In the event that WAVE grants a sublicense to a Third Party pursuant to Section 2.2, WAVE shall pay to MI the following percentages of the Sublicense
Consideration received, due within [***] days after receipt: 
  

					
	 Sublicense granted
	  	Percentage due to MI	 
		
	 [***]
	  	 	[***]	% 
	 [***]
	  	 	[***]	% 
	 [***]
	  	 	[***]	% 
	 [***]
	  	 	[***]	% 
	 [***]
	  	 	[***]	% 

 If WAVE receives any non-cash Sublicense Consideration, WAVE shall pay MI, at MI’s election, either (i) a cash
payment equal to the fair market value of the Sublicense Consideration, or (ii) the in-kind portion, if practicable, of the Sublicense Consideration. 

(b) Notwithstanding anything to the contrary in this Agreement, if WAVE, its Affiliates or Sublicensees grant a sublicense to a CMO for the purpose of having
the CMO manufacture a Licensed Product for the further development and/or commercialization of such Licensed Product solely by WAVE, its Affiliates or Sublicensees, no sublicense revenue will be due under this Section 5.5 as a result of such
sublicense. 
 (c) Relative Value of Pooled Technologies 

In the event of a Platform License, Drug Discovery Collaboration, or Development Collaboration, the percentage of the Sublicense Consideration due to MI
according to Subsection (a) above shall be based on the value reasonably attributable to the Patent Rights relative to the value of such other patent rights Controlled by WAVE included in such Platform License, Drug Discovery Collaboration, or
Development Collaboration (such relative value of the Patent Rights hereinafter the “Patent Rights Value”). 
 Together with a copy of any
sublicense agreement to be provided to MI according to Section 2.2(c), WAVE shall suggest to MI the Patent Rights Value based on a good faith fair market value determination, together with any information reasonably necessary or useful for MI
to evaluate such suggestion. If, within [***] days after receipt of the information, MI objects for cause to the suggested Patent Rights Value, Sec. 10.3 (b) applies accordingly. If MI fails to respond within [***] days after receipt of the
information, the Patent Rights Value shall be deemed accepted. 
  

***Confidential Treatment Requested***

 CONFIDENTIAL 

 

 (d) Fair Market Value Determination 

In the event that, according to this Agreement, a “fair market value” has to be determined, WAVE shall provide MI in due time with a good
faith determination of the fair market value, together with any information necessary or useful to support such determination. MI shall have the right to provide WAVE in due time with a counter-determination of the fair market value, which shall
include any information necessary or useful to support such counter-determination. If the Parties are unable to agree on a fair market value determination within [***] days after receipt of such counter-determination, Section 10.3
(b) applies accordingly. If either Party fails to respond to a fair market value determination provided by the other Party within [***] days of receipt, such Party will be deemed to have accepted the other Party’s fair market value
determination. 
 5.6 Reports 
 Starting with the first
commercial sale of a Licensed Product, within [***] ([***]) days of the end of each calendar half year, WAVE shall deliver a detailed report to MI for the immediately preceding calendar half year showing at least, on a Licensed Product-by-Licensed
Product and country-by-country basis, (i) the kind and number of Licensed Products sold by WAVE, its Affiliates, Sublicensees and their Sales Partners to the end users, (ii) the gross price charged, (iii) the calculation of Net Sales, and
(iv) the resulting running royalties due to MI according to those figures. If no running royalties are due to MI, the report shall so state. Reports provided to MI under this 5.6 shall be considered “Confidential Information” under
this Agreement. Additionally, MI understands that it is the intention of WAVE to become a publicly traded company and that any information disclosed to MI under this Agreement, including this 5.6, may be deemed “material non-public
information” under applicable securities laws. 
 5.7 Payments 

(a) Accounting Period and Payments

***Confidential Treatment Requested*** 

  
 page 13 of 23 

 CONFIDENTIAL 

 

 
shall be without deduction of exchange, collection, or other charges, except for deduction of withholding or similar taxes. The Parties shall use all reasonable and legal efforts to reduce tax
withholding on payments made to MI hereunder. Notwithstanding such efforts, if WAVE concludes that tax withholdings under the laws of any country are required with respect to payments to MI, WAVE shall withhold the required amount and pay it to the
appropriate governmental authority. In such a case, WAVE will promptly provide MI with original receipts or other evidence reasonably desirable and sufficient to allow MI to document such tax withholdings adequately for purposes of claiming foreign
tax credits and similar benefits. 
 (d) Late Payments 

Any undisputed payments that are not paid on or before the date such payments are due under this Agreement shall bear interest on arrears at [***]% ([***]
percentage points) per year. 
 5.8 Bookkeeping and Auditing 

WAVE is obliged to keep, and shall oblige its Affiliates, Sublicensees and Sales Partners to keep, complete and accurate books on any reports and payments due
to MI under this Agreement, which books shall contain sufficient information to permit MI’s certified public accountant (the “CPA”) to confirm the accuracy of any reports and payments made to MI. MI’s CPA is authorized to
check the books of WAVE not more than [***] per calendar year and, upon MI’s written request, within [***] days, WAVE shall provide records of its Affiliates, Sublicensees and Sales Partners in WAVE’s possession as part of such audit. The
charges for such a check shall be borne by MI. In the event that such check reveals an underpayment in excess of [***]% ([***] percent), WAVE shall bear the full cost of such check. In any event, WAVE shall remit any amounts due to MI within [***]
([***]) days of receiving notice thereof from MI, together with interest calculated in the manner provided in Section 5.7 (d). 
 The right of auditing
by MI under this Section shall expire [***] ([***]) years after each report or payment has been made. No period may be audited more than once. 
 5.9 No
Refund 
 All payments made by WAVE under this Agreement are non-refundable and non-creditable against each other (except for the creditability of annual
license maintenance fees against running royalties as set forth in Section 5.2, or the credit for an over-payment of running royalties). This Section 5.9 shall apply, without limitation, in the event this Agreement is terminated
prematurely in accordance with Article 9. 
 ARTICLE 6 - PATENT PROSECUTION AND INFRINGEMENT 

6.1 Responsibility for Patent Rights 
 MI shall be
responsible to apply for, seek issuance of, and maintain the Patent Rights. MI shall provide to WAVE copies of documents relevant to the filing, prosecution, maintenance and abandonment of the Patent Rights. MI shall designate counsel to prosecute

prosecution counsel. WAVE shall have the right to comment on decisions related to prosecution, maintenance and abandonment of the Patent Rights, and MI shall give good faith consideration to any such comments. MI, ISIS and WAVE shall cooperate in
good faith with each other, and shall use reasonable efforts to agree upon a joint strategy relating to the further filing, prosecution and maintenance of the Patent Rights. 

WAVE shall have the right to decide, in its sole discretion, in which countries the Patent Rights shall be filed, prosecuted and maintained during the Term. MI
is obliged, on a country-by-country basis, to file, prosecute and maintain the Patent Rights if and to the extent WAVE pays its respective patent costs relating thereto according to Section 6.2 below.

 6.2 Patent Costs 

WAVE shall pay [***]% ([***] percent) of all reasonable out of pocket fees and costs, including reasonable attorney’s fees, relating to the preparation,
filing, prosecution, and maintenance of the Patent Rights, which arise during the Term in accordance with Section 6.1 above. WAVE shall reimburse MI for the amounts due pursuant to this Section 6.2, within [***] ([***]) days after
receiving the respective invoice. MI shall have the right, in its sole discretion, to make a one time (only) election that such amounts shall be paid directly to MI’s patent attorneys, and shall provide WAVE with [***] ([***]) days advance
written notice of such election. In the event that solely WAVE (and not ISIS) intends to file, prosecute and maintain a certain patent application or patent within the Patent Rights in a certain country, then WAVE shall pay [***]% of all patent
costs relating to such Patent Right in such country. 
 6.3 Abandonment of Patent Rights 

In the event that WAVE intends to abandon (e.g. by non-payment of fees) any patent or patent application within the Patent Rights in a certain country, WAVE
shall notify MI hereof in writing in due time, at least [***] months prior to taking action or not taking action that will result in abandonment. MI (and (SIS) shall have the right, but not the obligation, to maintain such Patent Right in such
country in its sole discretion and at its sole expense. In any event, such Patent Rights shall no longer be covered by this Agreement after [***] months from the date WAVE informs MI of its abandonment, and WAVE shall remain obliged to pay its
respective patent costs share that arise during such [***] months-period. 
 6.4 Infringement of Patent Rights 

The Parties shall inform each other in due time in writing in the event a Party becomes aware of any suspected or actual infringement of the Patent Rights by
any Third Party, or any Third Party objection or other action (e.g. opposition, interference, revocation or nullity action) against the Patent Rights. MI shall have the right, but not the obligation, to enforce or defend the Patent Rights against
such Third Party in its sole discretion and at its sole expense. MI shall keep WAVE reasonably informed as to its enforcement and defense of the Patent Rights, and WAVE shall have the right to comment on the documents submitted in the course of such
action and the right to participate in all substantive strategic discussions with MI regarding such actions. If (A) within [***] months of the written notice above, MI (i) shall have been unsuccessful in persuading the alleged infringer to
desist, (ii) shall not have brought and shall not be diligently prosecuting an infringement action, or (iii) has not entered into settlement discussions with respect to such infringement, or (B) in the event that MI does not intend to
enforce or defend the Patent Rights, then WAVE (and ISIS) will have the right, but not the obligation, to individually or jointly (together with ISIS) enforce or defend the Patent Rights against such Third Parties at its or their respective sole
cost and expense, but in coordination with MI. MI shall promptly inform WAVE of this intent to not enforce or defend the Patent Rights pursuant to (B) above, but in no case less than the earlier to occur of (i) the expiration of such [***]
month period or (ii) [***] days prior to any deadline (unless impossible under the circumstances, in which case MI will provide such notice as soon as possible). In any case, the Parties shall negotiate in good faith how to proceed best, and
the Parties shall enter into a separate agreement regarding the allocation of responsibilities (including the initiation, performance and termination of mediation, arbitration or litigation, and the entering of settlements), costs and recoveries in
connection with any enforcement or defense of the Patent Rights. Notwithstanding the foregoing, (i) MI shall consult with WAVE prior to entering into any settlement, consent judgment or other voluntary disposition and (ii) any settlement,
consent judgment or other voluntary disposition of such actions which (1) limits the scope, validity, or enforceability of any Patent Rights, (2) subjects WAVE to any non-indemnified liability, payment obligation, or injunction, or
(3) admits fault or wrongdoing on the part of WAVE, must be approved in writing by WAVE.

7.1 Indemnification 
 WAVE shall indemnify, defend, and
hold harmless MI, MPG, UMMS, and their respective trustees, officers, faculty, students, employees, and agents and their respective successors, heirs and assigns (collectively the “Indemnitees”), against any and all third party
claims, suits, actions (including without limitation actions in the form of tort, warranty, or strict liability, demands, judgments, liabilities, losses, damages, costs, fees or expenses (collectively, the “Claims’’) incurred
by or imposed upon any of the indemnitees to the extent resulting from or arising out of (i) any use of the Patent Rights by WAVE, or (ii) any Licensed Product that is developed, made, used, or sold by WAVE, its Affiliates, Sublicensees
and Sales Partner pursuant to this Agreement, or (iii) any Third Party use of any such Licensed Product. 
 For purposes of clarity, in no event will a
Co-Exclusive Licensee have obligations to any Indemnitee for Claims resulting from or arising out of any use of the Patent Rights by the other Co-Exclusive Licensee, any Licensed Product that is developed, made, used, or sold by such other
Co-Exclusive Licensee, its Affiliates, Sublicensees and Sales Partners, or any Third Party use of any such Licensed Product. 
 7.2 Procedures 

The Indemnitees agree to provide WAVE with written notice of any Claims for which indemnification is sought under this Agreement within [***] days after the
Indemnitees have knowledge of such Claims. WAVE agrees, at its own expense, to provide attorneys reasonably acceptable to MI to defend against any such Claims; provided, however, that any Indemnitee shall have the right to retain its own
counsel, at its own expense, if representation of such Indemnitee by the counsel retained by WAVE would be inappropriate because of actual or potential differences in the interests of such Indemnitee and any other Party represented by such counsel.
The Indemnitees shall (i) permit WAVE to assume full responsibility to investigate, prepare for and defend against any such Claims (including all decisions relative to litigation, appeal, and settlement), and (ii) assist WAVE, at
WAVE’s expense, in the investigation, preparation and defense of any such Claims, and (iii) not compromise or settle such Claims without the prior consent of WAVE. WAVE shall keep MI informed of the progress in the defense and disposition

	(b)	to Third Party individuals with a professional obligation of secrecy (e.g. patent attorneys, attorneys-at-law, certified public accountants); 

 

	(c)	to Regulatory Authorities in connection with filings for Regulatory Approval, provided that such disclosures may be made only to the extent reasonably necessary to make such filings; and 

 

	(d)	if such disclosure is required by law or regulation (including without limitation by rules or regulations of any securities exchange, e.g. the United States Securities and Exchange Commission), provided that prior to

required to furnish. 

 Notwithstanding the foregoing, MI may disclose this Agreement and/or the Confidential Information on a confidential
basis to MPG, UMMS and to MPI-BC. 
 ARTICLE 9 - TERM AND TERMINATION 

9.1 Term 
 This Agreement shall come into effect on the
Effective Date, and it shall remain in effect until the later of (i) on a country-by-country and Licensed Product-by-Licensed Product basis, the expiration or abandonment of all Patent Rights covering a Licensed Product in such country, or

 9.2 Voluntary Termination by
WAVE 
 WAVE shall have the right to terminate this Agreement, without any reason, (i) upon at least 90 (ninety) days prior written notice to MI,

9.3 Cessation of Business 
 If WAVE and all of its
Affiliates and Sublicensees cease to carry on business related to this Agreement, WAVE shall inform MI thereof immediately. In such event, WAVE and MI shall each have the right to terminate this Agreement upon 30 (thirty) days prior written notice
to each other. 
 9.4 Change of Control 
 In the event
that a Third Party acquires, by a single transaction or a series of related transactions, more than 50% (fifty percent) of the securities or voting rights of WAVE, WAVE shall provide MI, upon MI’s request, with a special written report in
reasonable detail on the actual and intended future activities of WAVE to develop and commercialize Licensed Products. If WAVE cannot demonstrate to maintain, after the change of control event, a program to develop and commercialize Licensed
Products that is substantially similar or greater in scope to the program of WAVE prior to the change of control event, then MI shall have the right to terminate this Agreement upon 30 (thirty) days prior written notice to WAVE. WAVE shall inform MI
promptly of the implementation of any such change of control event. 
 9.5 Attack on Patent Rights 

MI shall have the right to terminate this Agreement upon 30 (thirty) days prior written notice to WAVE, if WAVE (or any of its Affiliates or Sublicensees)
attacks, or have attacked or support an attack through a Third Party, the validity of any of the Patent Rights. For the purposes of this Section 9.5, “attack” does not include interference proceedings at the United States Patent and
Trademark Office, or appeals related thereto. WAVE will not take affirmative action to 
  

***Confidential Treatment Requested*** 

  
 page 17 of 23

provoke such an interference, however MI recognizes that WAVE may be or may become a licensee to a pending U.S. application of a Third Party that could be deemed to interfere with applications
within the Patent Rights. 
 9.6 Termination for Material Breach 

(a) In the event WAVE (i) fails to pay any undisputed amounts due and payable to MI hereunder, and fails to make such payments within 45 (forty-five) days
after receiving written notice of such failure, or (ii) commits a material breach of its obligations under this Agreement other than a failure to pay, and fails to cure that breach within 60 (sixty) days after receiving written notice thereof,
MI may in each such event terminate this Agreement immediately upon written notice to WAVE. 
 (b) Notwithstanding the foregoing, if WAVE disputes in good
faith the existence or materiality of any such breach or alleged payment failure, and provides notice to MI of such dispute within such 45 (forty-five) day period for alleged payment failures, or within such 60 (sixty) day period for other alleged
material breaches, MI shall not have the right to terminate this Agreement in accordance with this Section 9.6 unless and until it has been determined in accordance with Section 10.3 (b) that this Agreement was materially breached by
WAVE, and WAVE fails to cure such breach within 30 (thirty) days following such determination. It is understood and acknowledged that during the pendency of such a dispute, all of the terms and conditions of this Agreement shall remain in effect and
the Parties shall continue to perform all of their respective obligations hereunder. 
 9.7 Effect of Termination

The following provisions shall survive the expiration or termination of this Agreement: Articles 1, 3, 5.6 through 5.8, 7, 8, 10 and this Section 9.7. In
no event shall the termination of this Agreement release WAVE from the obligation to make any reports and pay any amounts that became due on or before the effective date of termination. 

In the event that any license granted to WAVE under this Agreement is terminated, any sublicense under such license granted prior to termination of this
Agreement shall remain in full force and effect, provided that (i) the Sublicensee is not then in breach of its sublicense agreement, and (ii) the Sublicensee agrees, in writing within thirty (30) days after the effective date of
termination, to be bound to MI as licensor under the terms and conditions of the sublicense agreement, provided that MI shall have no other obligation than to leave the sublicense granted by WAVE in place. 

9.8 Insolvency 
 If WAVE shall become bankrupt, or shall
file a petition in bankruptcy, or if the business of WAVE shall be placed in the hands of a receiver, assignee or trustee for the benefit of creditors, whether by the voluntary act of WAVE or otherwise, WAVE shall provide notice thereof to MI and MI
may, subject to the effects of and protections of any applicable bankruptcy-related laws, rules, or regulations, terminate this Agreement upon written notice to WAVE. If this Agreement is terminated in accordance with this Section 9.8 with
respect to a Co-Exclusive Licensee, Article 2.1 shall apply with respect to the remaining Co-Exclusive Licensee.

Republic of Germany, without regard to the conflicts of laws provisions thereof, except that questions affecting the construction and effect of any patent shall be determined by the law of the country in which the patent shall have been granted.

 10.3 Dispute Resolution 
 (a) The Parties shall
attempt to settle any dispute or claim arising out of or relating to this Agreement by good faith negotiations. If the Parties fail to agree on a reasonable settlement within [***] ([***]) days after the affected Party informed the other Party in

any actual or threatened breach of this Agreement. 
 (b) Expedited Review of Disputes Regarding Material Breach 

If the Parties are in dispute as to whether WAVE is in material breach of this Agreement according to Section 9.6, then the arbitrators will first

 10.4 Assignment and Transfer 

This Agreement is personal to WAVE, and neither this Agreement nor any rights or obligations may be assigned or otherwise transferred by WAVE to a Third Party
without the prior written consent of MI. Notwithstanding the foregoing, WAVE may assign this Agreement to an Affiliate, or to a Third Party in connection with the merger, consolidation, sale of all or substantially all of its assets or that portion
of its business to which this Agreement relates; provided, however, that this Agreement shall immediately terminate if the proposed Third Party assignee fails to agree in writing to be bound by the terms and conditions of this Agreement on or before
the effective date of assignment. After the effective date of assignment, the Third Party assignee shall provide MI, upon MI’s request, with a special written report in reasonable detail on the actual and intended future activities of the Third
Party assignee to develop and commercialize Licensed Products. If the Third Party assignee does not maintain a program to develop and commercialize Licensed Products that is substantially similar in scope to the program of WAVE prior the effective
date of assignment, then MI may treat such failure as a material breach in accordance with Section 9.6. 
 10.5 Amendment and Waiver 

This Agreement may be amended, supplemented, or otherwise modified only by means of a written instrument signed by all Parties. Any waiver of any rights or
failure to act in a specific instance shall relate only to such instance and shall not be construed as an agreement to waive any rights or fail to act in any other instance, whether or not similar. 

10.6 Severability 
 Should one or more of the provisions
of this Agreement be held void, invalid or unenforceable under applicable law, the remaining provisions of this Agreement will not cease to be effective. The Parties shall negotiate in good faith to replace such void, invalid or unenforceable
provision by a new provision that reflects, to the extent possible, the original intent of the Parties. 
 10.7 Headings 

All headings are for convenience only and shall not affect the meaning of any provision of this Agreement. 

10.8 Entire Agreement 
 This Agreement contains the entire
understanding of the Parties with respect to the subject matter hereof, and any previous agreements and understandings, whether oral or written, made by the Parties on the same subject matter are expressly superseded by this Agreement. 

10.9 Force Majeure 
 Neither Party will be deemed to be in
default of this Agreement for failure or delay of the performance of its obligations or attempts to cure any breach of this Agreement, when such failure or delay is caused by or results from causes beyond the reasonable control of or not reasonably
avoidable by the affected Party, including, without limitation, embargoes, acts of war, strikes, lockouts or other labor disturbances, or acts of God. The affected Party will notify the other Parties of such force majeure circumstances as soon as
reasonably practical and will make every reasonable effort to mitigate the effects of such force majeure circumstances. In case of such a force majeure event, the time for performance or cure will be extended for the period equal to the duration of
such force majeure event, but not in excess of 6 (six) months.

venture or agency. Specifically, and not to limit the foregoing, with respect to each Co-exclusive Licensee, (i) the rights and obligations contained in this Agreement shall, except as expressly stated otherwise, apply to each Co-exclusive
Licensee individually, and not jointly and severally, and (ii) neither

 Exhibit 10.11 

DEED OF INDEMNITY 
 This Deed is made the
             day of 
 BETWEEN 

 

	(1)	Wave Life Sciences Pte. Ltd. (Company Registration Number 201218209G) a company duly incorporated in Singapore with its registered address at 8 Cross Street, #10-00 PWC Building, Singapore 048424 (the
“Company”); 

 AND 
  

	(2)	[NAME OF DIRECTOR OR OFFICER] [RESIDENTIAL/BUSINESS ADDRESS] (the “Indemnitee”); 

WHEREAS:- 
  

	A.	The Company desires and has requested the Indemnitee to serve or continue to serve as a director or officer (“Director” or “Officer”) of the Company. 

 

	B.	The Indemnitee is willing to serve, or to continue to serve, the Company in the aforementioned capacity subject to the execution and delivery by the Company of this Deed. 

NOW THIS DEED WITNESSETH THAT IN CONSIDERATION OF THE PREMISES:- 
  

	1.	Agreement to Serve. The Indemnitee hereby accepts the appointment as a Director or Officer of the Company and, so long as the Indemnitee continues to be a Director or Officer of the Company, the Indemnitee shall,
within the limits imposed by law, exercise all functions required by the Articles of Association of the Company (the “Articles”) while observing to the best of the Indemnitee’s ability the interests of the Company.

  

	2.	 Indemnification. Subject to, and to the maximum extent permitted by the Articles, the Companies Act (Chapter 50 of Singapore), as amended
from time to time (the “Act”) or other applicable law, the Company does hereby covenant and agree to hold harmless and indemnify the Indemnitee as from the date of appointment of the Indemnitee as a Director or Officer from and
against all matters of whatsoever nature and howsoever arising by reason of or in connection with the Indemnitee’s provision of services under clause 1 above (“Claims”). In addition to and not in limitation of the
indemnification otherwise provided for herein, and subject only to the exclusions set forth in clause 7 hereof, the Company hereby further agrees to hold harmless and indemnify Indemnitee against any and all expenses (including attorneys’
fees), witness fees, damages, judgments, fines and amounts paid in settlement and any other amounts that Indemnitee becomes legally obligated to pay in connection with any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, arbitrational, administrative or investigative (including, without limitation, an action by or in the right of the Company, and also including, without limitation, a claim, demand, discovery request, formal or informal investigation,
inquiry, administrative hearing, and any form of alternative 

	 	
dispute resolution), including an appeal from any of the foregoing (with each of the foregoing, and any appeal therefrom, being referred to as a “Proceeding”), to which
Indemnitee is, was or at any time becomes a party, or is threatened to be made a party, by reason of the fact that Indemnitee is, was or at any time becomes a director, officer, auditor, secretary, employee or agent of the Company, or is or was
serving or at any time serves at the Company’s request as a director, officer, employee or other agent of another company, partnership, joint venture, trust, employee benefit plan or other enterprise. 

 

	3.	Partial Indemnification. Notwithstanding any other provision of this Deed, to the extent that Indemnitee is a party to and is successful, on the merits or otherwise, in any Proceeding, Indemnitee shall be
indemnified to the maximum extent permitted by law against all expenses, liabilities, and other amounts described in clause 2 (collectively, the “Expenses”) actually and reasonably incurred by Indemnitee or on Indemnitee’s
behalf in connection therewith. To the extent that Indemnitee is not wholly successful but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in any Proceeding, then the Company shall indemnify
Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with each successfully resolved claim, issue or matter. 

 

	4.	Indemnification for Expenses of Witness. Notwithstanding any other provision of this Deed, to the extent that Indemnitee is, by reason of Indemnitee’s status as a director, officer, agent or employee of the
Company, a witness, or is made to asked to respond to discovery requests, in any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on
Indemnitee’s half in connection therewith. 

  

	5.	Advancement of Expenses. Notwithstanding any other provision of this Deed, the Company shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of
Indemnitee’s status as a director, officer, agent or employee of the Company within thirty (30) days after the receipt by the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time,
whether prior to or after final disposition of such proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall include or be preceded or accompanied by a written undertaking by or on behalf of
Indemnitee and shall include or be preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such
Expenses. Any advances and undertaking to repay pursuant to this clause 5 shall be unsecured and interest-free. 

  

	6.	Survival of Rights. All the rights and privileges afforded by this Deed, including the right to indemnification and the advancement of legal fees and expenses provided under this Deed, to the extent permissible
by law, shall continue as to Indemnitee for any action taken or not taken while serving in an indemnified capacity even though Indemnitee may have ceased to serve in such capacity at the time of any Proceeding. 

 

	7.	 Request for Indemnification. Whenever Indemnitee believes that the Indemnitee is entitled to indemnification pursuant to this Deed, the
Indemnitee shall submit a written request for 

  
 2 

	 	
indemnification to the Company. Any request for indemnification shall include sufficient documentation or information reasonably available to Indemnitee for the determination of entitlement to
indemnification. In any event, Indemnitee shall submit Indemnitee’s claim for indemnification within a reasonable time, not to exceed one year after becoming aware of the circumstances giving rise to the Indemnity’s entitlement to
indemnification. 

  

	8.	Exceptions to Indemnification. Notwithstanding anything in this Deed to the contrary, the Company will not provide indemnity with respect to any Claim: 

 

	 	(a)	settled without the Company’s consent, which consent, however, shall not be unreasonably withheld; 

  

	 	(b)	in respect of any liability that cannot be indemnified by reason of section 172 of the Act or other applicable law; 

  

	 	(c)	in connection with any claims, threats, or suits commenced by Indemnitee (other than any claims, threats, or suits commenced by Indemnitee to enforce Indemnitee’s rights under this Deed) unless the commencement of
such claims, threats, or suits was authorized by the Board of Directors; 

  

	 	(d)	on account of any determination or judgment against Indemnitee solely for an accounting of profits made from the purchase or sale by Indemnitee of securities of the Company pursuant to the provisions of
Section 16(b) of the United States Securities Exchange Act of 1934 and amendments thereto or similar provisions of any United States federal, state or local statutory law; 

 

	 	(e)	on account of Indemnitee’s conduct to the extent that it is established by a final, non-appealable judgment as knowingly fraudulent or deliberately dishonest or that constituted willful misconduct; or

  

	 	(f)	on account of Indemnitee’s conduct to the extent that it is established by a final, non-appealable judgment as constituting a breach of Indemnitee’s duty of loyalty to the Company or resulting in any personal
profit or advantage to which Indemnitee was not legally entitled. 

  

	9.	Subrogation. In the event of payment under this Deed, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee, who shall execute all papers required and
shall do everything that may be necessary to secure such rights, including the execution of such documents necessary to enable the Company effectively to bring suit to enforce such rights. 

 

	10.	 Directors and Officers Liability Insurance. The Company agrees that so long as Indemnitee serves as a director and/or officer of the Company,
and for so long thereafter as Indemnitee shall be subject to any possible Claim, by reason of the fact that the Indemnitee was serving in the capacity referred to herein (the “Indemnification Period”), the Company will maintain
directors’ and officers’ 

  
 3 

	 	
insurance for the benefit of the Indemnitee with established and reputable insurers, at coverage levels customary for companies comparable in size and business to the Company, and providing the
same rights and benefits as are accorded the Company’s and its subsidiaries’ then-current directors and officers. Upon receipt of notice of any Proceeding, the Company shall give or cause to be given prompt notice of such proceeding to all
insurers providing liability insurance in accordance with the procedures set forth in all applicable or potentially applicable policies. The Company shall thereafter take all necessary action to cause such insurers to pay all amounts payable in
accordance with the terms of such policies. 

  

	11.	Indemnification Procedures. The Indemnitee shall promptly notify the Company in writing upon being served with any document relating to a potential Claim that may result in the right to indemnification, but the
omission so to notify the Company will not relieve it from any liability that it may have to Indemnitee if such omission does not prejudice the Company’s rights. If such omission does prejudice the Company’s rights, the Company will be
relieved from liability only to the extent of such prejudice. Notwithstanding the foregoing, such omission will not relieve the Company from any liability that it may have to Indemnitee otherwise than under this Deed. With respect to any Claim as to
which Indemnitee notifies the Company of the commencement thereof: 

  

	 	(a)	the Company will be entitled to participate therein at its own expense; 

  

	 	(b)	the Company jointly with any other indemnifying party similarly notified will be entitled to assume the defence thereof. After notice from the Company to Indemnitee of its election to assume the defence thereof, the
Company will not be liable to Indemnitee under this Deed for any expenses subsequently incurred by Indemnitee in connection with the defence thereof, other than reasonable costs of investigation or otherwise as provided below. Indemnitee shall have
the right to employ separate counsel in such action, suit or proceeding, but the fees and expenses of such counsel incurred after notice from the Company of its assumption of the defence thereof shall be at the expense of Indemnitee unless
(i) the Company authorizes Indemnitee’s employment of separate counsel, (ii) Indemnitee reasonably concludes, and so notifies the Company, that there is an actual conflict of interest between the Company and Indemnitee in the conduct
of the defence of such action, or (iii) the Company shall not in fact have employed counsel to assume the defence of such action, in each of which cases the fees and expenses of Indemnitee’s separate counsel shall be at the Company’s
expense. The Company shall not be entitled to assume the defence of any action, suit or proceeding brought by or on behalf of the Company or as to which Indemnitee shall have made the conclusion provided for in clause (ii) above;

  

	 	(c)	the Company shall not settle any Claim in any manner that would impose any penalty or limitation on Indemnitee without Indemnitee’s written consent provided that Indemnitee will not unreasonably withhold his or her
consent to any proposed settlement; and 

  

	 	(d)	the Company shall advance the legal fees and expenses Indemnitee incurs in connection with such proceeding in accordance with clause 5 above; and 

  
 4 

	 	(e)	nothing in this clause 11 shall entitle Indemnitee to any indemnification, reimbursement or payment other than in accordance with section 172 of the Act and applicable law. 

 

	12.	Notices. All notices, requests, demands and other communications hereunder shall be in writing and shall be deemed to have been duly given if (i) delivered by hand and receipted for by the party to whom said
notice or other communication shall have been directed, or (ii) mailed by certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed: 

 

	 	(a)	If to Indemnitee, to: 

  

 
  

 
  

 
  

 
  

	 	(b)	If to the Company, to: 

 Wave Life Sciences Pte. Ltd. 

419 Western Avenue 
 Boston, MA
02135 
 USA 
 or to such other
address as may have been furnished to Indemnitee by the Company or to the Company by Indemnitee, as the case may be. 
  

	13.	Effective Period. This Deed shall be deemed to be effective as of the commencement date of the Indemnitee’s service as a director or officer of the Company and shall continue in effect during the
Indemnification Period. 

  

	14.	Amendment and Termination. The terms of this Deed may be changed, waived, discharged or terminated only by an instrument in writing signed by all parties. 

 

	15.	Non-Waiver. The failure of any party to insist in any one or more cases upon the strict performance of any provisions hereof shall not be a waiver or relinquishment for the future of such provisions, and receipt
by any part of any payment or benefit with knowledge of any default or breach by any other party shall not be a waiver of such default or breach. No delay by any party in exercising any of its or the Indemnitee’s powers or remedies hereunder or
a partial or single exercise thereof shall constitute a waiver thereof or a waiver of any power or remedy. The failure by any party to give notice to any other party of any breach hereof shall not constitute a waiver of the said breach.

  

	16.	Severability. The provisions of this Deed shall be severable, and if any provision or part thereof of this Deed shall be, or be found by any court of competent jurisdiction to be, invalid or unenforceable, the
invalidity or unenforceability of such provision shall not affect any other provision hereof or the enforceability or validity of that or any other provision in any other jurisdiction. 

  
 5 

	17.	Presumptions and Burden of Proof. The following procedures and presumptions shall apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Deed: 

 

	 	(a)	In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Deed.
Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

  

	 	(b)	It shall be presumed that Indemnitee has at all times acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to overcome this presumption
shall have the burden of proof by clear and convincing evidence. 

  

	 	(c)	In the event that any action, claim or Proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without limitation, settlement of such action,
claim or Proceeding with or without payment of money or other consideration), it shall be presumed that Indemnitee has been successful on the merits or otherwise in such action, suit or Proceeding. Anyone seeking to overcome this presumption shall
have the burden of doing so by clear and convincing evidence. 

  

	 	(d)	The termination of any Proceeding, or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly
provided in this Deed) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he reasonable believed to be in or not opposed to the best interests
of the Company or, with respect to any criminal proceeding, that Indemnitee had reasonable cause to believe that his conduct was unlawful. 

  

	18.	Non-Exclusivity. The rights conferred on Indemnitee by this Deed shall not be exclusive of any other right which Indemnitee may have or hereafter acquire under any applicable law, under the Articles, Bylaws,
other organizational document of the Company, under any agreement, insurance policy, or vote of stockholders, members or directors, or otherwise, both as to action in Indemnitee’s official capacity and as to action in another capacity while
holding office. 

  

	19.	 [Primacy of Indemnification. The Company hereby acknowledges that Indemnitee has certain rights to indemnification, advancement of
expenses, and/or insurance provided by [Names of Funds/Sponsors] and certain of their affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its
obligations to Indemnitee are primary, and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary); (ii) that it shall be required to
advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Deed
and the Articles or Bylaws of the 

  
 6 

	 	
Company (or any other agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors; and (iii) that it irrevocably waives,
relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the
Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing, and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the
extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Fund Indemnitors are express third-party beneficiaries of the terms of this clause [19].]
[Note: This paragraph will apply only to the directors that are appointed to the Board by the Fund Indemnitors.] 

  

	20.	Additional Indemnification Regarding Expenses. Without limiting the foregoing, in the event of an action instituted by or in the name of the Company under this Deed or to enforce or interpret any of its terms,
Indemnitee shall be entitled, to the extent permissible by law, to be paid all court costs and expenses, including attorneys’ fees, incurred by Indemnitee in defense of such action (including with respect to Indemnitee’s counterclaims and
cross-claims made in such action), unless as a part of such action the court determines that each of Indemnitee’s material defenses to such action were made in bad faith or were frivolous. 

 

	21.	Termination of Indemnitee’s Office. Nothing in this Deed shall be construed as requiring the Company to retain the Indemnitee in the office hereinbefore described, or as in any way restricting its rights to
remove the Indemnitee from office, or as requiring the Indemnitee to remain in office in the event that the Indemnitee wishes to resign from or relinquish such office. 

 

	22.	Duration of Agreement. The rights conferred on the Indemnitee by this Deed shall continue after the Indemnitee has ceased to be a director, officer, employee or other agent of the Company or to serve at the
request of the Company as a director, officer, employee or other agent of another company, partnership, joint venture, trust, employee benefit plan or other enterprise, and shall inure to the benefit of the Indemnitee’s successors, assigns,
heirs, executors and administrators. 

  

	23.	Successors and Assigns. This Deed shall be binding upon the Company and its successors and assigns. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business or assets of the Company, expressly to assume and agree to perform this Deed in the same manner and to the same extent the Company would be required to perform if no such succession had taken
place. 

  

	24.	Entire Agreement and Integration. This Deed shall contain the entire Deed among the parties with respect to the subject matter hereof and supersede all prior Deeds, written or oral, with respect thereto.

  
 7 

	25.	Counterparts. This Deed may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original, but all of which together shall constitute one and the same Deed.

  

	26.	Third-Party Beneficiaries. Except as provided in clause 19, a person who is not a party to this Deed shall have no right under the Contracts (Rights of Third Parties) Act (Chapter 53B) to enforce any of its
terms. 

  

	27.	Headings. The headings of the clauses of this Deed are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect its interpretation and construction.

  

	28.	Governing Law and Consent to Jurisdiction. This Deed shall be construed in accordance with and governed by the laws of Singapore, without regard to its conflict-of-laws rules. The parties hereto agree to submit
to the non-exclusive jurisdiction of the courts of Singapore for purposes of any action or proceeding arising out of or in connection with this Deed.
