For progressing the Back-Up Candidate, Pfizer will reimburse Wave each Pfizer Quarter for the actual costs for the Back-Up Candidate, beyond the costs already expended for the original candidate.

4.1.5. Alternate Targets. In the event that Pfizer, in its sole discretion, terminates any Pfizer Program, then Pfizer will have the right, exercisable within the first two (2) years after the Effective Date, to designate an alternate hepatic target for a Pfizer Program (an “Alternate Target”). Such designation of an Alternate Target for a Pfizer Program may be made by Pfizer during the Research Term only once for each of up to a total of three (3) Pfizer Programs. In the event that Pfizer designates an Alternate Target, Pfizer will pay to Wave an Alternate Target designation (“Alternate Target Designation”) milestone payment as described in Table 1 of Section 7.2.3, provided, [***]. Such alternate Pfizer Programs may be directed against any hepatic target directed toward a hepatic therapeutic condition of Pfizer’s choosing, provided that such Alternate Target is not a Wave Reserved Target listed in Exhibit D and is not at the time of designation either: [***].

4.1.6. Exclusivity.

(a) During the Research Term and a period of two (2) years thereafter, Wave will not itself (or through any Affiliate) research, Develop or Commercialize, and will not license to any Third Party or enter into any research, development or commercialization agreements with any Third Party, to use Wave Technology that is specific for the applicable hepatic target which is the basis of any Pfizer Program, provided, however that such obligations and restrictions shall expire automatically and immediately on a Pfizer Program-

by-Pfizer Program basis upon the date that either: (i) such Pfizer Program has been terminated by Pfizer under the termination provisions of Section 13.2, or (ii) Pfizer declines to exercise its Pfizer Option with respect to a Pfizer Program prior to expiration of the Option Period for such Pfizer Program or (iii) Pfizer fails to use Commercially Reasonable Efforts for such Pfizer Program or the Agreement has otherwise been terminated by Wave under Section 13.3 for a material breach by Pfizer with respect to such Pfizer Program or (iv) Pfizer has substituted the relevant target in respect of a Pfizer Program for an Alternate Target pursuant to Section 4.1.5. For clarity, the restrictions and obligations under this section shall not apply to the use of any Wave Technology in relation to any target that is not the subject of a Pfizer Program, and shall not apply to Wave for any target which has become the subject of a Wave Program in accordance with the provisions of Section 4.2 that is not at such time a target that is the subject of a Pfizer Program (including a Pfizer Program for which Pfizer has exercised its Option).

(b) During the Research Term and a period of one [***] thereafter, Pfizer will not itself (or through any Affiliate) research, Develop or Commercialize, and will not license to any Third Party or enter into any research, development or commercialization agreement with any Third Party, with respect to any [***].

4.2. Wave Programs. Subject to Section 4.1.6, Wave will have the right (but not the obligation) to designate therapeutic targets for stereochemically controlled Oligonucleotide therapies involving ssRNAi or Antisense Oligonucleotide (or any combination thereof) applications only for research, Development and Commercialization, incorporating Pfizer Technology, under the terms and conditions of this Agreement (each, a “Wave Program”). For clarity, Wave shall have no obligation to use Commercially Reasonable Efforts with respect to any of the Wave Programs or with respect to the use of any of the Pfizer Technology or with respect to the Development or Commercialization of any Product using or incorporating the Pfizer Technology. Also for clarity, in the event that the Pfizer Technology is initially used in a Wave Program but is subsequently not used in the Wave Program, Wave shall not owe to Pfizer any such subsequent milestone payment under this Agreement with respect to the Wave Program that is no longer using the Pfizer Technology. In the event that the Pfizer Technology is either rejected by a regulatory agency or is not incorporated as part of the final Product, Wave shall not owe to Pfizer any milestone or royalty payments under this Agreement subsequent to the rejection or removal from the Product with respect to any Products resulting from

such Wave Program that do not utilize the Pfizer Technology. [***]. Designation of a therapeutic target as the basis of a Wave Program under this Section 4.2 will be effective upon Wave delivering to Pfizer notice of the designation and of the identity of the therapeutic target, except if such proposed therapeutic target for a Wave Program is at such time already the basis of a Pfizer Program (including a Pfizer Program for which Pfizer has exercised its Option). Such designation may be made at any time during the Term. Subject to the terms and conditions of this Agreement, conduct of the Wave Program will be at the sole discretion of Wave.

4.3. Material Transfer. Wave and Pfizer may, during the Research Term, as a matter of course during any Pfizer Program or any Wave Program, or upon each other’s reasonable written request, furnish to each other samples of biochemical, biological or synthetic chemical materials which are part of Pfizer Technology or Wave Technology or Wave Hepatic Targeting Technology and that are necessary for each Party to carry out its responsibilities under the Research Plan or for Wave to perform its work under the Wave Program. Wave shall, upon request from Pfizer, deliver to Pfizer, subject to availability, a reasonable quantity of samples of any material made pursuant to and during activities described in the Research Plan. Any such samples provided (including any samples of the Oligonucleotides or Antisense Oligonucleotides provided by Wave to Pfizer) shall be used by Pfizer solely for purposes of the Research Program, and any quantities of such materials remaining at the end of the Research Term shall be returned to the Wave or destroyed, unless otherwise agreed between the Parties. Wave and Pfizer agree not to transfer such materials of the other Party to any Third Party, unless prior written consent for any such transfer is obtained from the other Party, and this sentence will survive the expiration or termination for any reason of this Agreement.

4.4. Subject to Section 4.1.6, nothing in this Agreement limits or alters Wave’s right to distribute Wave Materials to others or to use Wave Materials for its own purposes.

4.5. Nothing in this Agreement limits or alters Pfizer’s right to distribute Pfizer Materials to others or to use Pfizer Materials for its own purposes.

4.6. Each Party understands that the other Party’s Materials have not been approved for human use and agrees that the Materials may not be used to treat humans in any manner or form, subject to the Option.

shall be comprised of members from each Party as decided by each party and shall meet on an ad hoc basis from time to time as deemed necessary by either Party in order to address and oversee patent issues within the collaboration hereunder, subject to the provisions of this Agreement with respect to control of patent related activities.

5.1.6. Provisions Concerning the Filing and Prosecution of Patent Rights. Prior to filing any Patent Rights covering any Results under a Pfizer Program or a Wave Program, including for the avoidance of doubt any Patent Rights covering Wave Improvements or Pfizer Improvements, each Party shall notify and consult with the other through the Joint Patent Subcommittee, and shall take into reasonable account any comments that are timely provided by the other Party. Each Party shall provide the other with a copy of the draft application for any such Patent Rights for the other Party’s review and comment, no later than [***] days prior to filing such application.

Unless otherwise agreed in writing, Wave shall control all decisions and be solely responsible for the costs of preparing, filing and prosecuting any patent applications covering Wave Results or Wave Improvements and Pfizer shall control all decisions and be solely responsible for the costs of preparing, filing and prosecuting any patent applications covering Pfizer Results or Pfizer Improvements. Each Party shall provide the other with a copy of any application for any such Patent Rights filed during the Research Term, within [***] days of filing, and shall continue to cooperate in the prosecution and maintenance of such patent rights until exercise of the relevant Option or expiration of the period for such exercise. Prior to either Party filing any Patent Rights covering Joint Results (“Joint Patent Rights”), the Party wishing to file the Patent Rights shall notify and consult with the other Party through the Joint Patent Subcommittee, and the Parties will jointly determine a filing strategy for such Joint Patent Rights, including apportionment of costs and designation of a Prosecution Lead, being responsible for initial drafting and timely submission of any prosecution materials, and for prompt reporting to the other Party of any documents received from or submitted to any patent office worldwide.

If Pfizer exercises a Pfizer Option, responsibility (but not the obligation) for the filing, prosecution and maintenance of Patent Rights filed with respect to

Portions of this Exhibit, indicated by the xxxx “[***],” were omitted and have been filed separately with the

Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment

Page 20 of 64

Wave Results or Joint Results that (i) arise from the applicable Pfizer Program, (ii) are related to such Pfizer Option, and (iii) include specific claims to a Candidate Compound or Pfizer Product, its use, or manufacture will be transferred to Pfizer, including for the avoidance of doubt Patent Rights directed to a specific Stereochemically Pure ssRNAi or Antisense Oligonucleotide drug Candidate Compound Developed for the relevant Pfizer Program.

If Wave exercises a Wave Option, responsibility (but not the obligation) for filing, prosecution and maintenance of Patent Rights filed with respect to Pfizer Results or Joint Results that (i) arise from or are related to such Wave Program, and (ii) that include specific claims to a Wave Product, its use, or manufacture will be transferred to Wave, including for the avoidance of doubt Patent Rights directed to a specific Stereochemically Pure ssRNAi or Antisense Oligonucleotide drug candidate Developed for the relevant Wave Program.

In the event that Patent Rights arising from Results are desired to be filed covering both a Wave Improvement and a Pfizer Product, or a Pfizer Improvement and a Wave Product (the “Coordinated Patent Rights”), the Parties shall coordinate their patent filings and prosecution strategies in good faith via the Joint Patent Subcommittee and shall endeavor to file, wherever reasonably practical and appropriate, separate (e.g., continuation and/or divisional) patent applications that individually claim either the relevant Product or the relevant Improvement, but not both, if such separate filings would not adversely affect the prosecution strategy for either case. It is expected that the Joint Patent Subcommittee will normally appoint as Prosecution Lead for such separate filings the Party that owns the relevant Improvement or Product being claimed. Each Party shall provide the other Party with copies of any Information Disclosure Statements that it submits during prosecution under this Agreement of any Patent Rights in the United States, as well as lists of any other references or other art that is cited during prosecution under this Agreement of any Patent Rights in other patent offices.

In the event that Pfizer is Prosecution Lead for any particular patent application(s) within Coordinated Patent Rights, Wave agrees to, at Pfizer’s option: 1) reimburse Pfizer for all out of pocket costs related to filing, prosecution, or maintenance of claims in such Patent Rights which do not cover a Pfizer Product or 2) with [***] days written notice accept transfer

from Pfizer of responsibility, and pay all costs, for filing, prosecution, or maintenance of such claims. Furthermore, where Pfizer is Prosecution Lead for any particular patent application(s) within Coordinated Patent Rights and Wave expresses interest in having claims pursued in such application(s) that Pfizer indicates in writing that it does not wish to pursue in the application(s), Wave agrees to, at Pfizer’s option: 1) reimburse Pfizer for all out of pocket costs related to filing, prosecution, or maintenance activities directed to such claims or 2) with [***] days written notice accept transfer from Pfizer of responsibility, and pay all costs, for filing, prosecution, or maintenance of such claims.

It is agreed that one purpose of the Joint Patent Subcommittee is to ensure that each Party shall take into account in good faith any good faith comments by the other Party as to the scope of any claims pursued in any Patent Rights directed to specific Stereochemically Pure ssRNAi or Antisense Oligonucleotide drug candidates Developed for the relevant Pfizer Program or Wave Program.

It is agreed that Pfizer may use internal patent counsel, filing clerks and paralegals employed by Pfizer for its prosecution related activities, including for coordinating worldwide filings of such Patent Rights, for prosecution before the European Patent Office, and for directly instructing U.S. outside counsel and ex-U.S. patent agents, including providing draft applications and responses. It is also agreed that Pfizer may employ its preferred patent agents and/or members of the “Pfizer Legal Alliance” to conduct such activities as required for U.S. and ex-U.S. prosecution.

Following exercise of the Pfizer Option, Pfizer shall have the exclusive right, but not the obligation, to seek, in Wave’s name if so required, patent term extensions, supplemental protection certificates and the like available under Applicable Law, including 35 U.S.C. § 156 and applicable foreign counterparts, in any country in the Territory with respect to any Pfizer Product and in relation to Patent Rights exclusively licensed or assigned to Pfizer hereunder. Wave and Pfizer will cooperate in connection with all such activities, including executing any licenses required with respect to such extensions. Pfizer will give due consideration to all suggestions and comments of Wave regarding any such activities. In the event of a disagreement between the Parties, Pfizer will have the final decision-making authority; provided, however, that Pfizer will not seek to extend any Wave Patent Right or Wave Improvement without Wave’s agreement, unless licensed Patent Right may be extended without limiting Wave’s right to extend such licensed Patent Right for another product.

5.1.9.2. With Respect to Wave Products

Following exercise of the Wave Option, Wave shall have the exclusive right, but not the obligation, to seek in Pfizer’s name if so required, patent term extensions, supplemental protection certificates and the like available under Applicable Law, including 35 U.S.C. § 156 and applicable foreign counterparts, in any country in the Territory in relation to the relevant Wave Product. Wave and Pfizer will cooperate in connection with all such activities, including executing any licenses required with respect to such extensions. In the event of a disagreement between the Parties, Wave will have the final decision-making authority; provided, Wave shall not have the right, without Pfizer’s agreement, not to be unreasonably withheld, to seek an extension on any Patent Rights non-exclusively licensed to Wave under this Agreement. For the avoidance of doubt Pfizer’s agreement to extend a licensed patent may be withheld if Pfizer, in its reasonable judgment believes such extension may limit Pfizer’s right to extend such licensed Patent Right for another product.

Each Party will have the sole right, but not the obligation, to submit to all applicable Governmental Authorities patent information pertaining to its Products pursuant to 21 U.S.C. § 355(b)(1)(G) (or any amendment or successor statute thereto), any similar statutory or regulatory requirement enacted in the future regarding biologic products, or any similar statutory or regulatory requirement in any non-U.S. country or other regulatory jurisdiction.

5.1.15. Paragraph IV Type Notices. Notwithstanding any provision of this Agreement to the contrary, each Party will promptly (but in no event later than [***] following receipt or discovery, whichever occurs first) give written notice to the other Party of any certification of which it becomes aware filed pursuant to any statutory or regulatory requirement in any country in the Territory similar to 21 U.S.C. § 355(b)(2)(A)(iv) or 21 U.S.C. § 355(j)(2)(A)(vii)(IV) (or any amendment or successor statute thereto) claiming that any Patent Right licensed or assigned under the Agreement and covering any Party’s Compound or Product is invalid or that infringement will not arise from the Development, Manufacture, Commercialization or use in the Territory of such compound or Product by a Third Party. Upon the giving or receipt of such notice, the Party whose Compound or Product is relevant will have the sole right, but not the obligation, to bring an infringement action against such Third Party. In order to establish standing in connection with any action brought under this Section, the Parties will reasonably cooperate with each other and will timely commence or join in any such action if requested at the other Party’s expense. In the event of any conflict between the terms of this Section and the terms of any other Section, the terms of this Section will control and govern.

FORCE MAJEURE: Neither Party will be liable to the other Party for failure or delay in the performance of any of its obligations under this Agreement for the time and to the extent such failure or delay is caused by earthquake, riot, civil commotion, war, terrorist acts, strike, flood, or governmental acts or restriction that is beyond the control of the respective Party. The Party affected by such force majeure will provide the other Party with full particulars thereof as soon as it becomes aware of the same (including without limitation its best estimate of the likely extent and duration of the interference with its activities), and will use commercially reasonable efforts to overcome the difficulties created thereby and to resume performance of its obligations as soon as practicable.

26. ASSIGNMENTS: Neither Party will have the right to assign this Agreement or any part thereof to any Third Party without the prior written approval of the other Party; provided, however, that either Party may assign this Agreement in part or in whole, without the consent of the other Party, either to an Affiliate or if in connection with a merger, acquisition, consolidation or similar reorganization or the sale or transfer of all or substantially all of its assets or business relating to the subject matter of this Agreement, if the Affiliate or other assignee assumes all obligations of its assignor under this Agreement.

27. SEVERABILITY: When possible, each provision of this Agreement will be interpreted in such manner as to be effective, valid and enforceable under Applicable Law, but if any provision of this Agreement is held to be invalid or unenforceable under Applicable Law, such provision will he held invalid or unenforceable without invalidating the remainder of such provision or of this Agreement. The Parties will make a good faith effort to replace the invalid or unenforceable provision with a valid one, which in its economic effect is most consistent with the invalid or unenforceable provision.

28. RELATIONSHIP OF THE PARTIES: The Parties will perform their obligations under this Agreement as independent contractors and nothing in this Agreement is intended or will be deemed to constitute a partnership, agency, or employer-employee relationship between the Parties. Neither Party will have any right, power, or authority to assume, create, or incur any expense, liability, or obligation, express or implied, on behalf of the other Party.
