Execution Copy 
 SECOND AMENDED
AND RESTATED 
 STRATEGIC COLLABORATION AND 

LICENSE AGREEMENT 
 This
Second Amended and Restated Strategic Collaboration and License Agreement (the “Agreement”) is executed this January 8, 2015 (the “Second Restatement Date”), between Isis Pharmaceuticals, Inc., a Delaware corporation having
an address at 2855 Gazelle Court, Carlsbad, CA 92010 (“Isis”) and Alnylam Pharmaceuticals, Inc., a Delaware corporation having an address at 300 Third Street, Cambridge, MA 02142 (“Alnylam”). Isis and Alnylam may be referred to
herein as the “Parties,” or each individually as a “Party.” 
 GUIDING PRINCIPLES 

Isis is the leader in RNA-based drug discovery, has created technology, intellectual property, expertise, facilities and resources to discover
and develop oligonucleotide drugs; 
 Alnylam is the leader in RNAi therapeutics, has developed and acquired intellectual property,
expertise and technology in RNAi therapeutics, and is conducting research, drug discovery and development focused on Double Stranded RNA drugs; 

Isis and Alnylam desire to create a long-term strategic relationship that will enhance the positions of both companies in RNA-based drug
discovery; 
 Isis will continue to pursue RNA-based drug discovery technology very broadly including all potential mechanisms of action.
Isis will work with Alnylam as Isis’ primary means of participating in the potential value of Double Stranded RNA Products, and will not enter into any collaborations with Third Parties the primary purpose of which is to discover Double
Stranded RNA Products; 
 Alnylam will continue to pursue RNAi therapeutics and the use of Double Stranded RNA. Alnylam has no present plans
to pursue Single Stranded Products; 
 Isis and Alnylam are parties to the Amended and Restated Strategic Collaboration and License
Agreement dated April 28, 2009 (as amended to date, the “First Restated Agreement”), which amended and restated the Strategic Collaboration and License Agreement dated March 11, 2004 (as amended through April 28, 2009 (the
“First Restatement Date”), the “Original Agreement”) to, among other things, provide each Party with certain exclusive licenses to research, develop and commercialize Single Stranded RNAi Products for a limited pool of gene
targets, and co-exclusivity in the field of Single Stranded RNAi Compounds; and

4.3 Isis Enabled Targets for Single Stranded RNAi. 

(a) Enabled Targets. Isis will have a pool (the “Enabled Target Pool”) containing [***] slots for which Isis can
designate certain RNA Targets against which Isis intends to research, develop and commercialize a Single-Stranded RNAi Product (each such slot, an “Enabled Target Slot” and any RNA Target occupying such a slot, an “Enabled
Target”); provided, however, that, each time Isis designates as a Development Candidate a Single Stranded RNAi Product Designed for one of Isis’

Enabled Targets, then (i) such Enabled Target will be considered to have graduated from Isis’ Enabled Target Pool (a “Graduated Enabled Target”), (ii) Isis will be permitted
to designate a new Enabled Target to fill the open Enabled Target Slot in Isis’ Enabled Target Pool, and (iii) so long as Isis continues to maintain an Active Program for the applicable Single Stranded RNAi Product Designed for the
Graduated Enabled Target, such Graduated Enabled Target will remain an Enabled Target of Isis hereunder. For purposes of clarity, except as set forth in 6.1(h)(i) and 6.1(l), as applicable, Isis may not practice the Alnylam Patent Rights to
research, develop or commercialize a Single Stranded RNAi Product other than a Single Stranded RNAi Product Designed for one of Isis’ Enabled Targets. 

(b) [Intentionally Deleted] 

(c) Designating Enabled Targets. From time to time after the Second Restatement Date Isis may designate an RNA Target as an
Enabled Target upon written notice to Alnylam; provided, that there is an open Enabled Target Slot in the Enabled Target Pool. At no time during the period commencing with the Second Restatement Date and ending upon the expiration of the
Alnylam Exclusive Target Royalty Term may Isis designate an Alnylam Exclusive Target as an Enabled Target. 
 (d) Removing Enabled
Targets. From time to time after the Second Restatement Date Isis may remove an RNA Target from the Enabled Target Pool upon written notice to Alnylam (which removal will create an open Enabled Target Slot). In addition, on an Enabled
Target-by-Enabled Target basis, if Isis has not designated a Development Candidate comprising a Single Stranded RNAi Product Designed for the applicable Enabled Target before the [***] year anniversary of the date Isis added the applicable Enabled
Target to the Enabled Target Pool, then such RNA Target will be automatically removed from the Enabled Target Pool. Once Isis removes an RNA Target from its Enabled Target Pool (whether voluntarily or by operation of this Section 4.3(d)), such
RNA Target shall no longer be deemed an Enabled Target hereunder and Isis will be prevented from later adding such RNA Target to its Enabled Target Pool until [***] months have passed from the date such RNA Target was removed. 

(e) [Intentionally Deleted] 

(f) Confidentiality. The fact that Isis has designated or removed a particular RNA Target within the Enabled Target Pool is
Confidential Information of Isis, subject to the provisions of Article 12. Alnylam shall not disclose such Confidential Information of Isis to any Third Party, including its Third Party collaborators, or use such Confidential Information to guide
its own (or its Third Party collaborators’) decisions to pursue particular RNA Targets, but Alnylam can use such Confidential Information to decline a Third Party’s request for a license to such RNA Target.

 (l) Subject to the terms of Section 11.8, an exclusive license under Alnylam
Exclusive Target Patents to research, develop, make, have made, use, import, offer to sell and sell Isis Exclusive Target Products in the Field. 

6.2 License Option. For each RNA Target in the Isis DS-Target Pool (as further described below) Alnylam grants Isis an option to
obtain (on a Reserved DS-Target-by-Reserved DS-Target basis), subject to the terms and conditions of this Agreement, including, but not limited to, the restrictions set forth in Section 6.5, a non-exclusive license under, subject to the terms
of Section 11.8, Alnylam Current Motif and Mechanism Patents, Alnylam Current Chemistry Patents and Alnylam’s rights in Joint Patents, to research, develop, make, have made, use, import, offer for sale and sell Double Stranded RNA Products
that are Isis Products. 
 (a) This option will expire on a Reserved DS-Target-by-Reserved DS-Target basis if Isis has not paid
Alnylam the option fee set forth in Section 8.1 below before the earlier of (i) [***] with respect to such Reserved DS-Target, (ii) the [***] anniversary of the date such Reserved DS-Target [***] or the [***] anniversary of the date
such Reserved DS-Target [***] with a Third Party and Isis is contractually able to revoke such Third Party’s rights or (iii) the date Isis [***] with respect to such Reserved DS-Target. 

(b) For any Reserved DS-Target for which Isis obtains a license from Alnylam under this Section 6.2, Isis will use Commercially
Reasonable Efforts (either on its own or in an Antisense Drug Discovery Program or Development Collaboration) to develop and commercialize Double Stranded RNA Products that modulate such Reserved DS-Target. 

6.3 Sublicenses. 

(a) With respect to any license granted by Alnylam pursuant to Section 6.1(a), or 6.2, Isis may only grant a sublicense to a Third
Party solely for (i) the purpose of enabling such Third Party to collaborate with Isis in an Antisense Drug Discovery Program, or (ii) to develop and commercialize an Isis Product in a Development Collaboration. With respect to any license
granted by Alnylam pursuant to Section 6.1(c), 6.1(e), 6.1(g), Isis may grant a sublicense to a Third Party in connection with the discovery, development or commercialization of any product. Isis may grant sublicenses under Section 6.1(j).
With respect to the licenses granted by Alnylam pursuant to Section 6.1(h), Isis may only grant a sublicense to a Third Party to further the research, development or commercialization of an Isis Single Stranded RNAi Product that Isis has
performed on its own (or with Alnylam under the Research Program) and [***] at least [***]% of the work to discover and develop the Isis Single Stranded RNAi Product through the [***] (or a date that is earlier than [***] if requested by Isis and
approved in writing by Alnylam, such approval not to be unreasonably withheld). Isis is

not permitted to grant sublicenses under the license granted in Section 6.1(k), except that Isis is permitted to grant sublicenses in connection with a Bona Fide Third Party Collaboration.
Isis is permitted to grant sublicenses under the license granted in Section 6.1(l), except only that any such sublicense granted with respect to a Double Stranded RNA or a Double Stranded RNA Product is subject to Alnylam’s prior written
consent, which consent may be withheld in Alnylam’s sole discretion. Notwithstanding anything to the contrary in the foregoing, Isis is permitted to grant sublicenses under its licenses in Sections 6.1 and 6.2 to its Affiliates. 

(b) Notwithstanding anything in this Agreement to the contrary, Isis may not enter into any drug discovery collaboration the primary
purpose of which is to discover Double Stranded RNA Products and/or to develop Double Stranded RNA Products to any point up to the [***]. 

6.4 DS-Target Pool. 

(a) Reserved DS-Target Slots. On the Effective Date, Isis will have a pool (the “Isis DS-Target Pool”)
containing up to [***] slots for which Isis can designate certain RNA Targets other than the Alnylam Exclusive Targets solely for Antisense Drug Discovery Programs (each such slot, a “DS-Target Slot” and any RNA Target occupying such a
slot, a “Reserved DS-Target”); provided, however, that on January 1 of each year starting with January 1, 2007, Isis will gain the right to purchase one additional DS-Target Slot by
paying Alnylam [***] per each additional DS-Target Slot. These rights are cumulative and, subject to Section 17.2(c) do not expire during the License Term. Furthermore, in the event that Isis pays the [***] license option fee for a
Reserved DS-Target pursuant to Section 8.1, such Reserved DS-Target will be considered to have graduated from the Isis DS-Target Pool, and, subject to Section 6.4(e), Isis will be permitted
to designate a new Reserved DS-Target to fill the open DS-Target Slot in the Isis DS-Target Pool. For purposes of clarity, except as permitted under Sections 6.1(h)(i), Isis may not practice the Alnylam
Patent Rights to research, develop or commercialize Single Stranded RNAi Products for a Reserved DS-Target unless such Reserved DS-Target is designated as an Enabled Target by Isis pursuant to
Section 4.3(a) above. 
 (b) Initial Designations. The letter delivered by Isis to Alnylam on the Second Restatement Date
sets forth the Reserved DS-Targets as of the Second Restatement Date.

 (c) Removing/Adding DS-Targets. After the Second Restatement Date and no more than
once in any [***] month period (a “Target Reallocation Period”), Isis may do any of the following: 
 (i) Remove an
RNA Target from the Isis DS-Target Pool (which, following such removal will create an open DS-Target Slot); or 

(ii) Add a new RNA Target to any open DS-Target Slot (subject to the procedures and provisions of Section 6.4(e). 

Notwithstanding the foregoing provisions of this Section 6.4(c), in any Target Reallocation Period, Isis cannot remove a number of
Reserved DS-Targets that exceeds the number calculated by dividing the then current number of DS-Target Slots by [***] and rounding down to the nearest whole number. For the purpose of the limitation described in the immediately preceding sentence,
removing an RNA Target from the Isis DS-Target Pool and then filling the open DS-Target Slot created by such removal shall count as a single removal. Once Isis removes an RNA Target from the Isis DS-Target Pool, Isis will be prevented from later
adding such RNA Target to the Isis DS-Target Pool until [***] months have passed from the date Isis removed such RNA Target. 
 (d)
New Target Request. When Isis wishes to add a new RNA Target to occupy a vacant DS-Target Slot, it will provide Alnylam with written notice (the “Request Notice”) of the RNA Target it wishes to add (the “Proposed Reserved
DS-Target”). The Request Notice will include the gene name, and the NCBI accession number or nucleic acid sequence for the Proposed Reserved DS-Target. 

(e) New Target Rejection/Approval. Within [***] days of receipt of the Request Notice, Alnylam will give Isis written notice if
any of the criteria set forth below applied to such Proposed Reserved DS-Target at the time of Alnylam’s receipt of the Request Notice. If, at such time, the Proposed Reserved DS-Target is (i) subject to Alnylam’s own Active Program
[***], (ii) encumbered by a contractual obligation between Alnylam and a Third Party that would preclude Alnylam from granting a license under Section 6.2 with respect to the Proposed Reserved DS-Target, (iii) the subject of
Alnylam’s good faith negotiations to enter into a contractual obligation within the [***] months following receipt of the Request Notice with a Third Party (as supported by a written request from such Third Party) that would preclude Alnylam
from granting a license under Section 6.2 with respect to the Proposed Reserved DS-Target, or (iv) an Alnylam Exclusive Target, then the Proposed Reserved DS-Target will be rejected and will not become a Reserved DS-Target. If the Proposed
Reserved DS-Target is not rejected under this subsection (e), the Proposed Reserved DS-Target will become an Isis Reserved DS-Target. Alnylam will promptly notify Isis in writing if a rejected Proposed Reserved
DS-Target later becomes available to be designated as a Reserved DS-Target. 
 (f)
[Intentionally Deleted] 
 (g) Diligence on Rejected Targets. If (i) Alnylam rejects a Proposed Reserved
DS-Target under Section 6.4(e) above and (ii) Alnylam has [***]

with respect to such rejected Proposed Reserved DS-Target by the [***] anniversary of the date Alnylam rejected such Proposed Reserved DS-Target if Alnylam is working on such target alone, or the
[***] anniversary of the date Alnylam rejected such Proposed Reserved DS-Target if such rejected Proposed Reserved DS-Target is subject to a contractual obligation between Alnylam and a Third Party that would preclude Alnylam from granting a license
under Section 6.2 with respect to the rejected Proposed Reserved DS-Target but Alnylam [***], then [***] such rejected Proposed Reserved DS-Target [***]. 

(h) Diligence Obligations in Third Party Contractual Obligations. With the goal of minimizing contractual encumbrances on
Alnylam Patent Rights with respect to RNA Targets in the absence of a reasonable intent to discover and develop products that modulate such RNA Targets by Third Parties with which Alnylam enters into such contractual obligations, Alnylam intends to
seek reasonable diligence obligations from Third Parties in negotiating contracts between Alnylam and such Third Parties that would constitute contractual obligations of Alnylam that would preclude Alnylam from granting licenses to Isis under
Section 6.2 with respect to Proposed Reserved DS-Targets; or that would prevent Alnylam from granting Isis licenses with respect to Proposed Reserved DS-Targets; provided that Isis hereby acknowledges that such diligence
obligations are often heavily negotiated in biotechnology license and collaboration agreements and that this Section 6.4(h) shall not prevent Alnylam from entering into contracts between Alnylam and Third Parties in accordance with
Alnylam’s reasonable business judgment. 
 (i) Confidentiality. The fact that Isis has designated or removed a particular
RNA Target within the Isis DS-Target Pool is Confidential Information of Isis, or that Alnylam has rejected a particular RNA Target proposed for a DS-Target Slot or disallowed the redesignation of a particular RNA Target is Confidential Information
of Alnylam, subject to the provisions of Article 12. Neither Party shall disclose such Confidential Information of the other Party to any Third Party, including its Third Party collaborators, or use such Confidential Information of the other Party
to guide its own (or its Third Party collaborators’) decisions to pursue particular RNA Targets, but Alnylam can use such Confidential Information of Isis to decline a Third Party’s request for a license to such RNA Target. 

6.5 Limitations on Licenses. 

(a) The licenses granted under Sections 6.1(a) through (k) and 6.2 above do not grant any rights to Isis to practice the Alnylam
Excluded Technology. The license granted under Section 6.1(l) above does not grant any rights to Isis to practice the Alnylam Exclusive Target Excluded Technology. The licenses granted under Sections 6.1 and 6.2 above do not grant any rights to
Isis to practice the Alnylam Extended Field Patents or the Alnylam Exclusive Target Patents with respect to Agricultural Products in

will negotiate in good faith an appropriate license. 
 (b) Licenses to Alnylam Patent Rights, Alnylam Extended Field Patents or
Alnylam Exclusive Target Patents that are joint patents with Third Parties (i.e., invented by one or more Alnylam inventors and one or more non-Alnylam inventors) are licensed subject to the retained rights of any non-Alnylam inventors and their
assignees and licensees. There are no Alnylam Current Chemistry Patents or Alnylam Current Motif and Mechanism Patents subject to such retained rights. To Alnylam’s knowledge, as of the Second Restatement Date, there are no Alnylam Extended
Field Patents or Alnylam Exclusive Target Patents subject to such retained rights. 
 (c) Licenses to Alnylam Patent Rights, Alnylam
Extended Field Patents and Alnylam Exclusive Target Patents that are subject to contractual obligations between Alnylam and Third Parties in effect as of the Second Restatement Date are licensed subject to the restrictions and other terms of the
Alnylam Third Party Agreements. Prior to the Second Restatement Date, Alnylam has provided Isis with copies of the Alnylam Third Party Agreements, the Stanford Agreement and the CRT Agreement, provided in each case Alnylam may redact copies
of out-licenses Alnylam has granted Third Parties so long as the redacted terms do not limit Isis’ rights hereunder or create obligations for Isis. Isis hereby agrees to comply, and to cause its sublicensees to comply, with such restrictions
and other terms. 
 (d) Notwithstanding anything to the contrary herein, the licenses to Alnylam Patent Rights hereunder initially
shall not include licenses to Patents: 
 (i) licensed by Alnylam under the Agreement effective as of September 17, 2003
between The Board of Trustees of the Leland Stanford Junior University (“Stanford University”) and Alnylam Pharmaceuticals, Inc. (as amended, the “Stanford Agreement”); provided that with respect to any such
licensed Patents that are or become issued Patents, Isis shall have the option of expanding its licenses to Alnylam Patent Rights, Alnylam Extended Field Patents and/or Alnylam Exclusive Target Patents (as applicable) hereunder to include such
issued Patents by notifying Alnylam of such election and paying to Alnylam, in addition to all amounts otherwise payable to Alnylam hereunder (and without any right under Section 8.2 to reduce such otherwise payable amounts as a consequence of
such additional payment amounts), all amounts that become payable by Alnylam to Stanford University pursuant to the Stanford Agreement as a result of such expansion of Isis’ licenses and Isis’ (and its Affiliates’ and
sublicensees’) exercise of its rights thereunder. Upon exercise of such option, the Stanford Agreement will be an Alnylam Third Party Agreement and Exhibit 6.5(c) updated accordingly, such Patents will be licensed to Isis subject to the
restrictions and other terms of the Stanford Agreement and Isis hereby agrees to comply, and to cause its sublicensees to comply, with such restrictions and other terms;

 (ii) licensed by Alnylam under the License Agreement effective July 18, 2003 between
Cancer Research Technology Limited (“CRT”) and Alnylam Pharmaceuticals, Inc. (as amended, the “CRT Agreement”); provided that with respect to any such licensed Patents that are or become issued Patents, Isis shall
have the option of expanding its licenses to Alnylam Patent Rights, Alnylam Extended Field Patents and/or Alnylam Exclusive Target Patents (as applicable) hereunder to include such issued Patents by notifying Alnylam of such election and paying to
Alnylam, in addition to all amounts otherwise payable to Alnylam hereunder (and without any right under Section 8.2 to reduce such otherwise payable amounts as a consequence of such additional payment amounts), all amounts that become payable
by Alnylam to CRT pursuant to the CRT Agreement as a result of such expansion of Isis’ licenses and Isis’ (and its Affiliates’ and sublicensees’) exercise of its rights thereunder. Upon exercise of such option, the CRT Agreement
will be an Alnylam Third Party Agreement and Exhibit 6.5(c) updated accordingly, such Patents will be licensed to Isis subject to the restrictions and other terms of the CRT Agreement and Isis hereby agrees to comply, and to cause its sublicensees
to comply, with such restrictions and other terms; 
 (iii) that are Additional Rights (as defined in Section 11.8) Controlled
by Alnylam’s wholly-owned subsidiary Sirna Therapeutics, Inc. as of the Second Restatement Date. If during the License Term Isis wishes to include such Additional Rights under the licenses granted to it by Alnylam pursuant to Article 6, Isis
will notify Alnylam of its desire to do so and will assume all financial and other obligations to the licensors and/or sellers of such Additional Rights to Alnylam arising from the grant to Isis of such licenses. The Parties will negotiate in good
faith regarding sharing any upfront payments or similar acquisition costs incurred by Alnylam to acquire such Additional Rights. 
 (e)
Notwithstanding the licenses and other rights granted to Isis under Sections 6.1 and 6.2, Alnylam retains its rights in the Alnylam Patent Rights, the Joint Patents and the Alnylam Extended Field Patents exclusively for Alnylam Exclusive
Targets. Notwithstanding the exclusive nature of the license granted by Alnylam to Isis under Section 6.1(l), Alnylam may grant Permitted Licenses. 

(f) The license to Alnylam Extended Field Patents granted in Section 6.1(k) does not include any rights with respect to Single
Stranded Products that are designed to modulate any Isis Retained Targets. 
 6.6 Alnylam Covenant to Isis Regarding Exclusivity

Products that are not Isis Exclusive Target Products for [***]; (ii) and may grant licenses to Third Parties to, research, develop, make, have made, use and/or import Alnylam Exclusive Target Products; and (iii) continue to grant licenses
to Third Parties for the purpose of manufacturing and selling oligonucleotides; provided that, to the extent such licenses cover Single Stranded RNAi Compounds, Alnylam will restrict such licenses to [***]. For purposes of clarity,
this Section 6.6 will not preclude Alnylam from (A) itself using [***], or (B) granting any Third Party a license under the [***]. 

6.7 Diligence on Isis Exclusive Targets. For each Isis Exclusive Target, Isis will use Commercially Reasonable Efforts (either
on its own, with an Affiliate or in a Bona Fide Third Party Collaboration) [***]. 
 ARTICLE 7 

LICENSE FEES AND ROYALTIES PAYABLE TO ISIS 

7.1 License Fees. 

(a) In connection with the Original Agreement, Alnylam paid Isis an initial, irrevocable, noncreditable and non-refundable license fee
of $5,000,000. 
 (b) In connection with the First Restated Agreement, Alnylam paid Isis an additional, irrevocable, noncreditable
and non-refundable license fee of $11,000,000. 
 7.2 Royalties. 

(a) Subject to the terms and conditions of, and during the term of, this Agreement, Alnylam will pay to Isis royalties on sales of
Alnylam Double Stranded RNA Products (other than Agricultural Field Products) by Alnylam, its Affiliates or sublicensees (except Naked Sublicensees) equal to [***]% of Net Sales of such Products. Alnylam may reduce the royalty due under this section
by [***]% of any additional royalties that Alnylam owes to Third Parties on such Alnylam Double Stranded RNA Product (other than an Agricultural Field Product) that arise from Alnylam acquiring access to new technologies after the Effective Date;
provided, however that (x) the royalty due under this section can never be less than a floor of [***]% and (y) additional royalties arising as the result of the addition, pursuant to Section 11.8, of Isis Current
Chemistry Patents, Isis Current Motif and Mechanism Patents to the Isis Patent Rights licensed to Alnylam cannot be used to reduce the royalty.

 (b) Subject to the terms and conditions of this Agreement, and during the Alnylam Extended
Field Royalty Term, Alnylam will pay to Isis royalties on sales of Alnylam Extended Field Products (other than Agricultural Field Products) by Alnylam, its Affiliates or sublicensees equal to [***]% of Net Sales of such Products. 

(c) Subject to the terms and conditions of this Agreement, and during the Alnylam Exclusive Target Royalty Term, Alnylam will pay to
Isis royalties on sales of Alnylam Exclusive Target Products (other than Agricultural Field Products) by Alnylam, its Affiliates or sublicensees equal to [***]% of Net Sales of such Products. Upon expiration of the Alnylam Exclusive Target Royalty
Term, the license granted under Section 5.1(h) will terminate. 
 (d) Subject to the terms and conditions of, and during the
term of, this Agreement, Alnylam will pay to Isis royalties on sales of Agricultural Field Products by Alnylam, its Affiliates or sublicensees equal to [***]% of Agricultural Field Product Net Sales. Alnylam may not reduce the royalty due under this
subsection (d) for any additional royalties that Alnylam owes to Third Parties on such Agricultural Field Products. 
 (e) The
royalties payable to Isis pursuant to Section 7.2(c) are in addition to, and not in lieu of, the royalties payable to Isis pursuant to Section 7.2(a). Specifically, if an Alnylam Exclusive Target Product (other than an Agricultural Field
Product) is subject to the payment of royalties to Isis pursuant to Section 7.2(c) during the applicable Alnylam Exclusive Target Royalty Term and is also an Alnylam Double Stranded RNA Product, then the royalty calculated pursuant to
Section 7.2(a) above will also be payable to Isis with respect to such Alnylam Exclusive Target Product for so long as such Alnylam Exclusive Target Product is an Alnylam Double Stranded RNA Product. However, if an Alnylam Exclusive Target
Product that is subject to the payment of royalties to Isis pursuant to Section 7.2(c) is also an Alnylam Extended Field Product, it will not be subject to additional royalties under Section 7.2(b). Otherwise, only one royalty shall be due
under this Section 7.2 with respect to the same unit of Product and if during any period the application of Sections 7.2(a), (b) and/or (c) to such Product in a country would result in different royalty rates being applied in order to
calculate the royalty due with respect to Net Sales of such Product in such country in such period, then the greatest applicable royalty rate shall be applied.

 (b) [Intentionally Deleted] 

(c) Double Stranded Development Milestones. Alnylam, its Affiliates or sublicensees (except Naked Sublicensees) will pay to Isis the
following milestone payments for each Alnylam Double Stranded RNA Product within [***] days after the first achievement of each of the following events: 
  

					
	 Milestone Event
	  	Milestone Payment	 
	 Initiation of Phase I Trial
	  	US$	375,000	  
	 Initiation of Phase III Trial
	  	US$	750,000	  
	 Filing NDA
	  	US$	[***]	  
	 Marketing Approval
	  	US$	[***]	  

 Each milestone payment under this Section 7.3(c) will only be due on the [***] Alnylam Double Stranded
RNA Product that modulates a particular RNA Target to trigger such milestone payment, whether such milestone is achieved by Alnylam or an Affiliate or sublicensee of Alnylam. 

Notwithstanding the foregoing, the provisions of this Section 7.3(c) shall not apply to any Agricultural Field Product. 

(d) MicroRNA Milestone. Alnylam, its Affiliates or sublicensees will pay to Isis a milestone payment of US$[***] for the [***] MicroRNA
Product that is an Alnylam Product that modulates a particular RNA Target within [***] days after such MicroRNA Product reaches the initiation of [***], and not for any other MicroRNA Product that is an Alnylam Product that modulates the particular
RNA Target. 
 7.4 Sublicensing Revenue on Naked Sublicenses. With respect to Sublicense Revenue from each Naked Sublicense
granted by Alnylam and its Affiliates under this Agreement, Alnylam will pay Isis within [***] days following receipt by Alnylam of such Sublicense Revenue (a) fifty percent (50%) of all such Sublicense Revenue that does not constitute
royalty payments, and (b) [***] percent ([***]%) of the amount that remains of the total royalties received under such Naked Sublicense after Alnylam has paid the royalties that are due from Alnylam to any Third Parties in connection with such
Naked Sublicense. 
 7.5 Technology Access Fees from Certain Collaborations. 

(a) Alnylam will pay Isis a percentage of Technology Access Fees received by Alnylam and its Affiliates pursuant to Bona Fide Discovery
Collaborations and Development Collaborations entered into between Alnylam and a

Third Party. Alnylam shall make such payment to Isis within [***] days following receipt by Alnylam of such Technology Access Fees. Such percentage will be calculated based on the year in which
Alnylam executes such Bona Fide Discovery Collaboration or Development Collaboration agreement using the following table: 
  

																	
	 Year
	  	2004/2005	 	 	2006	 	 	2007	 	 	2008+	 
	 Applicable Percentage
	  	 	[***]	% 	 	 	[***]	% 	 	 	[***]	% 	 	 	[***]	% 

 However, Alnylam may credit any milestone payments made by Alnylam under Section 7.3(c) above with
respect to an Alnylam Double Stranded RNA Product against any Technology Access Fees that are later due under a Bona Fide Discovery Collaboration or Development Collaboration that involves the same Alnylam Double Stranded RNA Product that triggered
such milestone payment. 
 If Alnylam grants a sublicense under the Isis Exclusive Target Patents where the Patents sublicensed thereunder
include Patents that are also Isis Patent Rights, then such sublicense will be treated as a Bona Fide Discovery Collaboration for purposes of this Section 7.5(a) and Alnylam will pay Isis a percentage of Technology Access Fees received by
Alnylam and its Affiliates in connection with such sublicense. However, if Alnylam grants a sublicense under the Isis Exclusive Target Patents and/or the Isis Extended Field Patents and the Patents sublicensed thereunder do not include Isis Patent
Rights (and do not include Isis Exclusive Target Patents that are also Isis Patent Rights), then no payments are due under this Section 7.5(a). 

(b) Notwithstanding the foregoing, for any Bona Fide Discovery Collaboration or Development Collaboration agreement, Alnylam will pay
Isis a minimum fee, payable upon the first Alnylam Product other than a Single Stranded RNAi Product developed pursuant to such Bona Fide Discovery Collaboration agreement reaching [***] (in which event Alnylam shall pay Isis such minimum fee within
[***] days following such initiation of [***]) or within [***] days after the execution of such Development Collaboration agreement, equal to the lesser of (i) [***] or (ii) [***]% of the Technology Access Fees from such collaboration;
provided, however that Alnylam may credit any amounts paid Isis pursuant to Section 7.5(a) above as the result of the same Bona Fide Discovery Collaboration or Development Collaboration agreement against this minimum fee with such
amounts credited only once, and provided further that if following such payment, additional Technology Access Fees are owed to Isis for such Bona Fide Discovery Collaboration or Development Collaboration, the amounts paid under this
Section 7.5(b) (after crediting of any previous Technology Access Fees paid under Section 7.5(a) in accordance with the immediately preceding proviso) will be creditable against such future Technology Access Fees. Notwithstanding the
foregoing, the provisions of this Section 7.5(b) shall not apply to any Bona Fide Discovery Collaboration involving solely Agricultural Field Products.

 7.6 Allocation of Sublicense Income. Each time Alnylam enters into a collaboration
or license agreement pursuant to which Alnylam grants a sublicense under the Isis Patent Rights to a Third Party that only relates to Double Stranded RNA (an “Isis IP Sublicense”), the CEO of Isis and the CEO of Alnylam will mutually
discuss and agree in writing upon a good faith determination as to whether such Isis IP Sublicense is a Naked Sublicense or a Bona Fide Discovery Collaboration or Development Collaboration or Bona Fide Third Party Collaboration. Within [***] days
following the execution of each Isis IP Sublicense, Alnylam, through its CEO, will provide Isis’ CEO a reasonably detailed and accurate description of such Isis IP Sublicense for the purpose of enabling the CEOs to perform the determination and
allocation described in this Section 7.6. 
 7.7 Revenue Sharing for Research Program Patents. Alnylam will pay Isis 50%
of any payments received by Alnylam and its Affiliates pursuant to licenses granted by Alnylam to a Third Party under the Research Program Patents for any and all purposes, except to research, develop, make, have made, use, import, offer to
sell or sell any (1) oligonucleotides (or chemically modified oligonucleotide analogs) designed to work via the RNase H 1 or 2 mechanism (including any oligonucleotide which has [***]), (2) Double Stranded RNA Products, (3) MicroRNA
Products, (4) Single Stranded RNAi Products, (5) Isis Single Stranded Product, or (6) Alnylam Exclusive Target Products. Alnylam shall make such payment to Isis within [***] days following receipt by Alnylam of such payments.

hereunder is not made when due, the payment will bear interest from the date due at the lesser of (i) 1.5% per month, compounded monthly, or (ii) the highest rate permitted by law;
provided, however, that in no event will such rate exceed the maximum legal annual interest rate. If a Party disputes in writing the amount of an invoice presented by the other Party within [***] days of receipt of such invoice, interest will
only be due on the correct amount as later determined or agreed. The payment of such interest will not limit a Party from exercising any other rights it may have as a consequence of the lateness of any payment. In addition, each Party agrees to pay
all external costs of collection, including reasonable attorneys’ fees, incurred by the other Party in enforcing the payment obligations after a due date has passed under this Agreement. 

9.3 Audit Rights. 

(a) Upon the written request of Isis or Alnylam, as the case may be, and not more than once in each calendar year, Isis or Alnylam will
permit the other Party’s independent certified public accountant to have access upon reasonable advance notice and during normal business hours to its records as may be reasonably necessary to verify the accuracy of the royalty reports
hereunder for the current year and the preceding 2 years prior to the date of such request. The accounting firm will disclose to the auditing Party only whether the royalty reports are correct or incorrect, the specific details concerning any
discrepancies, and the corrected amount of Net Sales and royalty payments. No other information will be provided to the auditing Party. Once a Party has audited a particular calendar year under this section, the Party will be precluded from
subsequently auditing such calendar year. In any sublicense granted by a Party under this Agreement, such Party will endeavor to secure a similar audit right and if reasonably requested by the other Party will enforce such audit right. 

(b) If such accounting firm concludes that additional royalties were owed during such period, the delinquent Party will pay the
additional royalties within 90 days of the date such Party receives the accounting firm’s written report. The fees charged by such accounting firm will be paid by the auditing Party unless the additional royalties, milestones or other payments
owed by the audited Party exceed 5% of the royalties, milestones or other payments paid for the time period subject to the audit, in which case the audited Party will pay the reasonable fees and expenses charged by the accounting firm. 

(c) Each Party will treat all financial information subject to review under this Section 9.3 or under any sublicense agreement in
accordance with the confidentiality provisions of Article 12, and will cause its accounting firm to enter into an acceptable confidentiality agreement obligating such firm to retain all such financial information in confidence pursuant to such
confidentiality agreement.

 9.4 Taxes. If laws, rules or regulations require withholding of income taxes or
other taxes imposed upon payments set forth in Article 7 or 8, each Party will make such withholding payments as required and subtract such withholding payments from the payments set forth in Article 7 or 8. Each Party will submit appropriate proof
of payment of the withholding taxes to the other Party within a reasonable period of time. The Parties will cooperate to obtain the appropriate tax clearance and/or recover any such withholdings if possible. 

ARTICLE 10 
 ALNYLAM
RIGHTS OF FIRST NEGOTIATION; PREFERRED LICENSEE 
 10.1 Right of First Negotiation. Isis will notify Alnylam in writing
once (i) Isis, on its own with no subsequent rights to Third Parties, intends to initiate [***] for an Isis Product that is a Double Stranded RNA Product or (ii) if a Third Party with which Isis has a Development Collaboration or a
collaboration on an [***] an Isis Double Stranded RNA Product before or during clinical development or commercialization with no subsequent rights to Third Parties. Alnylam will have [***] days from the receipt of such notice to notify Isis in
writing whether or not Alnylam wishes to negotiate with Isis regarding the development and/or commercialization of such Isis Product. If Alnylam fails to respond to Isis’ notice within the [***] days or if Alnylam declines in writing to
exercise its right of first negotiation, then Isis will be free to develop and commercialize (either on its own or with a Third Party) the Isis Product. If Alnylam wishes to negotiate a license or development or commercialization rights in such Isis
Product, the Parties will negotiate in good faith the terms of the license or collaboration agreement. If, despite good faith negotiations, Alnylam and Isis do not reach agreement within [***] days from Alnylam’s exercise of its right of first
negotiation, then Isis will be free to develop and commercialize (either on its own or with a Third Party) the Isis Product; provided that during the period prior to the latest of (x) the initiation of [***] the Isis Product,
(y) the [***] anniversary of the commencement of [***] for the Isis Product or (z) in the case of an Isis Product [***] after the commencement of [***], the [***] anniversary of Isis’ notice to Alnylam [***], Isis shall not enter into
a license or collaboration agreement with a Third Party for such Isis Product on terms (the “More Favorable Terms”) that are in the aggregate materially more favorable to the Third Party than the terms on which Isis most recently offered
in writing to grant such rights to Alnylam without first offering the More Favorable Terms to Alnylam. 
 10.2 Preferred
Licensee. If, after the Effective Date, Alnylam grants to any Third Party that is not a Major Pharmaceutical Company a license under the Alnylam Patent Rights to develop and commercialize Double Stranded RNA Products, then if (a) either
(i) the [***] terms of such license are more favorable to the Third Party than the [***] terms hereunder with respect to Isis Products are to Isis or (ii) the [***] covered by such license exceeds the [***] potentially licensed to Isis
hereunder for development and

commercialization of Double Stranded RNA Products, and (b) the roles to be played by Alnylam and such Third Party in the development and commercialization of Double-Stranded RNA Products
under such Third Party license, the nature of the RNA Targets covered by such Third Party license and any other relevant terms of such Third Party license do not collectively justify the conditions described in the preceding clauses (a)(i) and/or
(a)(ii), then Alnylam shall modify the terms of its licenses to Isis hereunder with respect to such conditions so that they are reasonably equivalent to those granted to the Third Party. The Parties agree that the provisions of this
Section 10.2 shall not apply to licenses involving solely Agricultural Field Products. 
 ARTICLE 11 

INTELLECTUAL PROPERTY 

11.1 Ownership of Inventions. 

(a) Each Party will solely own all inventions, technology, discoveries, or other proprietary property (collectively,
“Inventions”) that are made (as determined by U.S. rules of inventorship) solely by employees of or consultants to that Party under this Agreement. 

(b) Isis and Alnylam will jointly hold title to all Inventions, whether or not patentable, that are made (as determined by the U.S.
rules of inventorship) jointly by employees of or consultants to Isis and Alnylam, as well as to Patents filed thereon. Such Inventions will be “Joint Inventions,” and Patents claiming such Joint Inventions will be “Joint
Patents.” Isis and Alnylam will promptly provide each other with notice whenever a Joint Invention is made. The Parties agree and acknowledge that, except insofar as this Agreement provides otherwise, the default rights conferred on joint
owners under US patent law, including the right of each Party to independently practice, license and use a Joint Patent, will apply in relation to the Joint Patents throughout the world as though US patent law applied worldwide. 

(c) The Parties agree, upon reasonable request, to execute any documents reasonably necessary to effect and perfect each other’s
ownership of any Invention. 
 11.2 Filing and Prosecution of Patent Rights. 

(a) [Intentionally Deleted] 

(b) Except as set forth in Sections 11.2(f) and 11.2(h) below, Isis will be responsible for preparing, filing, prosecuting, maintaining
and taking such other actions as are reasonably necessary or appropriate with respect to the Isis Patent Rights, the Isis Extended Field Patents and the Isis Exclusive Target Patents.

 (c) Except as set forth in Section 11.2(g) and 11.2(h) below, Alnylam will be
responsible for preparing, filing, prosecuting, maintaining and taking such other actions as are reasonably necessary or appropriate with respect to the Alnylam Patent Rights, the Alnylam Extended Field Patents and the Alnylam Exclusive Target
Patents. 
 (d) Each Party will endeavor in good faith to coordinate its efforts with those of the other Party to minimize or avoid
interference with the prosecution of the Patents that are licensed under this Agreement. Neither Party will initiate or participate in any opposition, reexamination, interference, litigation, inter partes review, post grant review or other
proceeding for the purpose of narrowing or invalidating any claim in a Patent of the other Party; provided, however, that either Party may assert invalidity or non-infringement as a defense in any court
proceeding bought by the other Party asserting infringement of a granted Patent that is not a Patent then licensed under this Agreement. Notwithstanding the above, if an interference is declared by the Patent and Trademark Office between two or more
of the Parties respective Patents, the Parties agree to use good faith diligent efforts to resolve matters of priority and patentability and reach agreement or understanding as to patentable claims enjoying priority. In the event the Parties do not
reach such agreement or understanding within [***] months after declaration of the interference by the Patent and Trademark Office (or such shorter period as necessary to comply with the Patent and Trademark Office calendar), then the Parties agree
to submit such matter to arbitration under Section 17.6 and that the Party determined not to have priority of invention with request and agree to adverse judgment either by way of concession of priority or unpatentability or by disclaimer or
abandonment of the contest according to the rules of interference practice in existence at the time. The Parties agree to file with the Patent and Trademark Office all agreements pertaining to settlement of the interference in accordance with the
rules of interference practice in existence at the time. 
 (e) At the non-prosecuting Party’s request, the other Party will
keep the requesting Party reasonably informed, and provide documentation, of all material matters relating to the preparation, filing, prosecution and maintenance of any designated Patent licensed to the non-prosecuting Party under this Agreement.

 (f) Alnylam will be responsible for preparing, filing, prosecuting, maintaining and taking such other actions as are reasonably
necessary or appropriate with respect to the (i) Isis Exclusive Target Patents that (1) claim (x) an oligomeric compound that hybridizes to and modulates an Alnylam Exclusive Target or (y) a method of using such oligomeric
compound in the Field and (2) cover the manufacture, sale or use of an Alnylam Exclusive Target Product that is comprised of a

Double Stranded RNA or Double Stranded RNA Product (“Isis Special Target Patent”) and (ii) Isis Special Patents. If Alnylam elects not to file for or continue the prosecution
(including any interferences, oppositions, reissue proceedings and re-examinations) or maintenance of an Isis Special Patent or an Isis Special Target Patent in any country, then, Alnylam will notify Isis promptly in writing of its intention in
sufficient time to enable Isis to meet any deadlines by which an action must be taken to establish or preserve any such rights in such Patent in such country and Isis will have the right, but not the obligation, to file for or continue the
prosecution or maintenance of such Patent in such country, and Alnylam will cooperate with Isis in regard thereto. If elections with respect to obtaining patent term extension or supplemental protection certificates or their equivalents in any
country with respect to Isis Special Target Patents are available, Alnylam shall have the right (but not the obligation), in its sole discretion, to make any such election and make such filing as necessary to effect such election. Alnylam shall, in
its sole discretion, seek and maintain all applicable data exclusivity periods (such as those periods listed in the FDA’s Orange Book (including any available pediatric extensions) or foreign equivalents) that are available for Alnylam
Exclusive Target Products. Alnylam shall have sole authority with respect to the listing of any Isis Special Target Patents with respect to the Alnylam Exclusive Target Products in the Orange Book. 

(g) Isis will be responsible for preparing, filing, prosecuting, maintaining and taking such other actions as are reasonably necessary
or appropriate with respect to the Patents that (1) claim (x) an oligomeric compound that hybridizes to and modulates an Isis Exclusive Target or (y) a method of using such oligomeric compound in the Field and (2) cover the
manufacture, sale or use of an Isis Exclusive Target Product that is comprised of a Single Stranded Compound or Single Stranded Product (“Alnylam Special Target Patent”). If Isis elects not to file for or continue the prosecution
(including any interferences, oppositions, reissue proceedings and re-examinations) or maintenance of an Alnylam Special Target Patent in any country, then, Isis will notify Isis promptly in writing of its intention in sufficient time to enable
Alnylam to meet any deadlines by which an action must be taken to establish or preserve any such rights in such Patent in such country and Alnylam will have the right, but not the obligation, to file for or continue the prosecution or maintenance of
such Patent in such country, and Isis will cooperate with Isis in regard thereto. If elections with respect to obtaining patent term extension or supplemental protection certificates or their equivalents in any country with respect to Alnylam
Special Target Patents are available, Isis shall have the right (but not the obligation), in its sole discretion, to make any such election and make such filing as necessary to effect such election. Isis shall, in its sole discretion, seek and
maintain all applicable data exclusivity periods (such as those periods listed in the FDA’s Orange Book (including any available pediatric extensions) or foreign equivalents) that are available for Isis Exclusive Target Products. Isis shall
have sole authority with respect to the listing of any Alnylam Special Target Patents with respect to the Isis Exclusive Target Products in the Orange Book.

 (h) Solely with respect to (i) Research Program Patents, or (ii) Patents
licensed under this Agreement that claim Inventions that primarily relate to Single Stranded RNAi Compounds, in each case that are Controlled by Alnylam but excluding Joint Patents, Alnylam will be responsible for preparing, filing, prosecuting,
maintaining and taking such other actions as are reasonably necessary or appropriate with respect to such Patent. If Alnylam decides to discontinue the preparation, filing, prosecution or maintenance of such a Patent, Alnylam will notify Isis at
least [***] days prior to any deadline that, if missed, would materially prejudice the Patent, and Isis will have the right, at Isis’ own expense, to prepare, file, prosecute and maintain such Patent. 

11.3 Filing and Prosecution of Jointly Owned Patents. 

(a) The Parties will mutually agree on which of the Parties will be designated as being the responsible Party for preparing, filing,
prosecuting, maintaining and taking such other actions as are reasonably necessary or appropriate with respect to each Joint Patent. 

(b) Each Party will keep the other Party continuously informed of all significant matters relating to the preparation, filing,
prosecution and maintenance of Joint Patents, and shall provide the other Party with copies of any substantial prosecution papers within thirty days of receipt. 

11.4 Costs and Expenses. 

(a) Except as set forth in Section 11.4(c) and (d) below, each Party will bear its own costs and expenses in filing,

(b) Except as set forth in Section 11.4(c) and (d) below, the Parties will pay equal shares of all costs and expenses in
filing, prosecuting, maintaining and extending the Joint Patents. 
 (c) Alnylam will bear [***]% of its own costs and expenses in
filing, prosecuting, maintaining and extending the Isis Special Patents and the Isis Special Target Patents. If Alnylam elects not to file for or continue the prosecution (including any interferences, oppositions, reissue proceedings and
re-examinations) or maintenance of an Isis Special Patent or an Isis Special Target Patent in any country, and Isis assumes the continued prosecution of such Isis Special Patent or Isis Special Target Patent (as permitted by Section 11.2(f)) in
such country, then the Parties will [***] all of Isis’ costs and expenses in filing, prosecuting, maintaining and extending the Isis Special Patent or Isis Special Target Patent for which Isis assumed prosecution.

 (d) Isis will bear [***]% of its own costs and expenses in filing, prosecuting,
maintaining and extending the Alnylam Special Target Patents. If Isis elects not to file for or continue the prosecution (including any interferences, oppositions, reissue proceedings and re-examinations) or maintenance of an Alnylam Special Target
Patent in any country, and Alnylam assumes the continued prosecution of such Alnylam Special Target Patent (as permitted by Section 11.2(g)) in such country, then the Parties will [***] all of Alnylam’s costs and expenses in filing,
prosecuting, maintaining and extending the Alnylam Special Target Patent for which Alnylam assumed prosecution. 
 11.5
Enforcement. 
 (a) Each Party will promptly advise the other of any suspected or actual infringement of the Isis Patent
Rights, Alnylam Patent Rights, Joint Patents, Alnylam Extended Field Patents, Alnylam Exclusive Target Patents, Isis Extended Field Patents or Isis Exclusive Target Patents by any person that reasonably affects the other Party’s business and of
which it becomes aware. The notice shall set forth the facts of such infringement or misappropriation in reasonable detail. 
 (b)
Subject to subsections (c)(i) and (h) below, Alnylam will have the sole and exclusive right, in its sole discretion and at its expense, to assert and enforce (i) any Isis Patent Rights, Alnylam Patent Rights, Joint Patents, Alnylam

(ii) any Isis Exclusive Target Patents against any party engaging in an unlicensed or unauthorized making, having made, using, selling, offering for sale or importing of any allegedly infringing oligomeric compound that hybridizes to and
modulates an Alnylam Exclusive Target but only if such Isis Exclusive Target Patent is the only Patent Controlled by Alnylam that covers such allegedly infringing oligomeric compound. 

(c) 
 (i) For any
enforcement by Alnylam under subsection (b) above that includes Isis Patent Rights or Isis Exclusive Target Patents covering a [***] chemical modification, Isis will actively participate in the planning and conduct of such enforcement and will
take the lead of such enforcement to the extent that the scope or validity of any such Isis Patent Rights, Isis Extended Field Patents or Isis Exclusive Target Patents covering a [***] chemical modification is at risk. 

(ii) Subject to subsection (b) above and subsection (h) below, Isis will have the sole and exclusive right, in its sole
discretion and at its expense, to assert and enforce Alnylam Exclusive Target Patents against any party engaging in an unlicensed or unauthorized making, having made, using, selling, offering for sale or

importing of any allegedly infringing oligomeric compound that hybridizes to and modulates an Isis Exclusive Target but only if such Alnylam Exclusive Target Patent is the only Patent Controlled
by Isis that covers such allegedly infringing oligomeric compound. 
 (d) Except as set forth in Sections 11.5(b), (c) and (h),

 (i) Isis will have the sole and exclusive right, in its sole discretion and at its expense, to assert and enforce any
(i) Isis Patent Rights, (ii) Isis Extended Field Patents, and (iii) Isis Exclusive Target Patents; 
 (ii) Alnylam
will have the sole and exclusive right, in its sole discretion and at its expense, to assert and enforce any (i) Alnylam Patent Rights, (ii) Alnylam Extended Field Patents, (iii) Alnylam Exclusive Target Patents, and (iv) the
Isis Special Patents; and 
 (iii) The Parties will agree in advance on the enforcement of any Joint Patent and will apportion
enforcement responsibilities and recoveries amongst the Parties. 
 (e) The rights granted hereunder to Alnylam to enforce certain
licensed in or jointly owned Isis Patent Rights are further limited by the terms of the Isis Third Party Agreements. The rights granted hereunder to Isis to enforce certain licensed in or jointly owned Alnylam Patent Rights are further limited as
described in the Alnylam Third Party Agreements. 
 (f) The nonenforcing Party will have the right, at its own expense, to
participate in the conduct of the enforcement action and to be represented in such action by its own counsel. 
 (g) The enforcing
Party will not enter into any settlement that impacts the validity, scope or interpretation of any claim of any Joint Patent or of any Patent of the nonenforcing Party licensed to the nonenforcing Party under this Agreement without prior written
authorization of the nonenforcing Party. 
 (h) If the Party with enforcement rights under subsection (b), (c) or (d) above
(the “Primary Party”) fails to initiate proceedings against any actual or suspected infringement within [***] days of receipt of written request for enforcement from the other Party (the “Step-in Party”) and if the infringer is
directly competing with a Product (the “Affected Product”) of such Step-in Party, then (i) if the license granted in this Agreement under which the Step-in Party is selling the Affected Product is exclusive or co-exclusive, the Step-in Party will have the right to assert and enforce the patents that are allegedly being infringed, or (ii) if the license granted in this Agreement under which

the Step-in Party is selling the Affected Product is non-exclusive, the Step-in Party will have no obligation to pay royalties during the period for which the Primary Party fails to initiate
proceedings or take other action (including without limitation entering into a licensing arrangement) to eliminate such infringement; provided that the provisions of the immediately preceding clause (ii) shall not apply if the
Primary Party elects to grant the Step-in Party enforcement rights with respect to such infringement. The Primary Party will not grant a license to any such infringing Third Party with respect to any directly competitive infringing product on terms
materially more favorable (milestones and royalties) than the terms of the license granted hereunder to the Step-in Party or, solely with respect to the Affected Product, will adjust the terms of such license so that they are not materially less
favorable than the terms of the license granted to the infringing Third Party. In addition, as a condition to the Step-in Party’s right (under clause (i) of this Section 11.5(h)) to assert and enforce a Patent Controlled by the
Primary Party that is allegedly being infringed, the Step-in Party must also assert and enforce any relevant Patents Controlled by such Step-in Party against the alleged infringer who is competing with the Affected Product. 

(i) Except as otherwise agreed to by the Parties as part of a cost-sharing arrangement, any recovery realized as a result of such
litigation, after reimbursement of any reasonable litigation expenses of Isis and Alnylam, shall be retained by the Party or Parties that brought and controlled such litigation for purposes of this Agreement, except that any recovery realized as a
result of such litigation shall be treated as Net Sales of the applicable Products and distributed as such Net Sales would have been distributed. 

11.6 If any Person asserts in writing or in any legal proceeding that any of the Isis Exclusive Target Patents or Alnylam Exclusive
Target Patents are unenforceable based on any term or condition of this Agreement, the Parties shall amend this Agreement as may reasonably be required to effect the original intent of the Parties, including to preserve the enforceability of such
Patents and the intended economic and non-economic effects of this Agreement. 
 11.7 [Intentionally Deleted] 

11.8 Future Licenses. If after the First Restatement Date, a Party (the “Controlling Party”) invents or acquires
rights or title to an invention claimed by a Patent that (i) would be included in the Isis Current Chemistry Patents, Isis Current Motif and Mechanism Patents, Isis Extended Field Patents or Isis Exclusive Target Patents if such Party is Isis
or in the Alnylam Current Chemistry Patents, Alnylam Current Motif and Mechanism Patents, Alnylam Extended Field Patents or Alnylam Exclusive Target Patents if such Party is Alnylam (the “Additional Rights”) and (ii) carry financial
or other obligations, then the Controlling Party must promptly notify the non-Controlling Party of such acquisition or invention. If the non-Controlling Party

wishes to include such Additional Rights under the licenses granted pursuant to Article 5 or 6, as applicable, the non-Controlling Party will notify the Controlling Party of its desire to do so
and will assume all financial and other obligations to the Controlling Party’s licensors or collaborators, if any, arising from the grant to the non-Controlling Party of such license. Any Additional Rights that do not carry financial or other
obligations shall be automatically included under the licenses granted pursuant to Article 5 or 6, as applicable. If a Party pays any upfront payments or similar acquisition costs to access Additional Rights, the Parties will negotiate in good faith
regarding sharing such acquisition costs and payments. When acquiring or creating such Additional Rights, each Party will endeavor in good faith to secure the right to sublicense such Additional Rights to the other Party.

First Restated Agreement) without the express prior written consent of Isis, and, subject to Section 4.3(f), neither Party shall disclose the other Party’s past or current Enabled Targets without the express prior written consent of the
other Party. 
 12.3 Announcements; Publicity. 

(a) Each Party understands that this Agreement is likely to be of significant interest to investors, analysts and others, and that
either Party therefore may make public announcements with respect to this Agreement. The Parties agree that any such announcement will not contain confidential business or technical information unless disclosure of confidential business or technical
information is required by law or regulation, in which case they will make reasonable efforts to minimize such disclosure of confidential business or technical information to that required by law or regulation. Each Party agrees to provide to the
other Party a copy of any such public announcement as soon as reasonably practicable under the circumstances prior to its scheduled release. Except under extraordinary circumstances, each Party shall provide the other with an advance copy of any

17.4 Force Majeure. Neither Party will be held liable or responsible to the other Party nor be deemed to have defaulted under or

embargoes, acts of war (whether war be declared or not), insurrections, riots, civil commotions, acts of terrorism, strikes, lockouts or other labor disturbances, or acts of God. The affected Party will notify the other Party of such force majeure

meet for attempted resolution by good faith negotiations within 15 days after the expiration of the preceding 30 day period. 
 (b)
In the event the designated executive officers are not able to resolve such dispute during such 15-day period, then any such dispute shall be resolved through binding arbitration under the Commercial Arbitration Rules of the American Arbitration
Association by a panel of three arbitrators appointed in accordance with such rules. The Parties shall be entitled to the same discovery as permitted under the U.S. Federal Rules of Civil Procedure; provided that the panel shall be
entitled in its discretion to grant a request from a Party for expanded or more limited discovery. The award of the arbitrators shall be the sole and exclusive remedy between the Parties regarding any such dispute. An award rendered in connection
with an arbitration pursuant to this Section 17.6 shall be final and binding upon the Parties and any judgment upon such award may be entered and enforced in any court of competent jurisdiction. Any arbitration pursuant to this
Section 17.6 shall be conducted in San Diego, California if Alnylam initiates the arbitration or in Boston, Massachusetts if Isis initiates the arbitration. Nothing in this Section 17.6 shall be construed as limiting in any way the right
of a Party to seek an injunction or other equitable relief with respect to any actual or threatened breach of this Agreement or to bring an action in aid of arbitration. Should any Party seek an injunction or other equitable relief, or bring an
action in aid of arbitration, then for purposes of determining whether to grant such injunction or other equitable relief, or whether to issue any order in aid of arbitration, the dispute underlying the request for such injunction or other equitable
relief, or action in aid of arbitration, may be heard by the court in which such action or proceeding is brought. 
 17.7 No
Consequential Damages. IN NO EVENT WILL EITHER PARTY OR ANY OF ITS RESPECTIVE AFFILIATES BE LIABLE TO THE OTHER PARTY OR ANY OF ITS AFFILIATES FOR SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, WHETHER IN CONTRACT, WARRANTY, TORT,

convenience to assist in locating and reading the several Articles and Sections hereof. 
 17.9 Waiver. The waiver by either
Party hereto of any right hereunder, or the failure to perform, or a breach by the other Party will not be deemed a waiver of any other right hereunder or of any other breach or failure by said other Party whether of a similar nature or otherwise.

 17.10 Compliance with Law. Nothing in this Agreement will be deemed to permit a
Party to export, re-export or otherwise transfer any Product sold under this Agreement without compliance with applicable laws. 
 17.11
Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained
herein will not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affect the substantive rights of the Parties. The Parties will in such an instance use their best efforts to replace the
invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, maintains the balance of the rights and obligations of the Parties under this Agreement. 

17.12 Waiver of Rule of Construction. Each Party has had the opportunity to consult with counsel in connection with the review,
drafting and negotiation of this Agreement. Accordingly, the rule of construction that any ambiguity in this Agreement will be construed against the drafting Party will not apply. 

17.13 Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but
all of which together will constitute one and the same instrument. 
 17.14 Performance by Affiliates. To the extent that this
Agreement imposes obligations on Affiliates of a Party, such Party agrees to cause its Affiliates to perform such obligations. 
 17.15
No Implied License. Except as expressly provided in Sections 5.1, 6.1 and 6.2 of this Agreement, no Party will be deemed by estoppel or implication to have granted the other Party any license or other right with respect to any
intellectual property of such Party.

	83.	“MicroRNA Construct” is a construct having the chemical and physical description of a Double Stranded RNA that is either (a) designed to target a precursor microRNA or a microRNA, thereby to inhibit the
production or function of the microRNA, or (b) designed to function by mimicking the translational repressor function of a naturally occurring microRNA, and which, in relation to its target RNA, has been demonstrated in vitro and, to the extent
reasonably feasible, in vivo, to function solely as a translational repressor and not via cleavage of such target RNA. 

  

	84.	“MicroRNA Product” means a pharmaceutical product that contains a MicroRNA Construct. 

  

	85.	“Motif and Mechanism Patents” means any Patent that covers an oligomeric structure or composition of matter, or any method of using or incorporating such oligomeric structure or composition of matter in vitro

insurance charges, (iv) taxes, duties or other governmental tariffs (other than income taxes) and (v) government-mandated rebates and (vi) a reasonable reserve for bad debts.
Except in the cases of Products used to conduct clinical trials, reasonable amounts of Products used as marketing samples and Product provided without charge for compassionate or similar uses, a Party, its Affiliates or sublicensees will be treated
as having sold Products for an amount equal to the fair market value of Products if: (a) Products are used by such Party, its Affiliates or sublicensees without charge or provision of invoice, or (b) Products are provided to a Third Party
by such Party, its Affiliates or sublicensees without charge or provision of invoice and used by such third party. 

 Such
amounts shall be determined from the books and records of Alnylam or Isis (as applicable) and their respective Affiliates and sublicensees, maintained in accordance with GAAP, consistently applied. 

In the event the Product is sold as part of a Combination Product (as defined below), the Net Sales from the Combination Product, for the
purposes of determining royalty payments, shall be determined by multiplying the Net Sales (as determined without reference to this paragraph) of the Combination Product, during the applicable royalty reporting period, by the fraction, A/A+B, where
A is the average sale price of the Product when sold separately in finished form and B is the average sale price of the other product(s) included in the Combination Product when sold separately in finished form, in each case during the applicable
royalty reporting period or, if sales of both the Product and the other product(s) did not occur in such period, then in the most recent royalty reporting period in which sales of both occurred. In the event that such average sale price cannot be
determined for both the Product and all other products(s) included in the Combination Product, 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 the fair market value of the Product and D is the fair market value of all other product(s) included in the Combination Product. As used above, the term “Combination Product” means any pharmaceutical product which consists
of a Product and other therapeutically active pharmaceutical compound or any delivery technology that embodies substantial intellectual property rights Controlled by the selling Party (e.g., a common syringe would not constitute a delivery
technology that embodies substantial intellectual property rights Controlled by the selling Party, but an implantable delivery device such as a stent would constitute such a delivery technology). 

Notwithstanding anything in this Agreement to the contrary, where the term “Net Sales” is used in this Agreement to apply to
Agriculture Field Products, in such context the term “Net Sales” shall be replaced with “Agricultural Field Product Net Sales”.

 EXHIBIT 8.2(c) 

DESCRIPTION OF ALNYLAM ROYALTY OBLIGATIONS TO [***] EXISTING 

AS OF THE EFFECTIVE DATE 
 As of the
Effective Date, Alnylam has the following royalty obligations to [***]: 
 Alnylam is obligated to pay [***] running royalties on NET SALES
(as defined in Alnylam’s agreements with [***]) of therapeutic and prophylactic LICENSED PRODUCTS (as defined in Alnylam’s agreements with [***]) by Alnylam and its SUBLICENSEES (as defined in Alnylam’s agreements with
[***]) that range from [***]% ([***] percent) to [***]% ([***] percent) of NET SALES, depending on the level of NET SALES. Royalties payable by Alnylam to [***] are subject to the following Royalty Stacking
provision: 
 “5.3 Royalty Stacking 
 (a) Third Party
Licenses 
 In the event COMPANY or a SUBLICENSEE takes, for objective commercial and/or legal reasons, a license from any third party under any patent
applications or patents that dominate the PATENT RIGHTS or is dominated by the PATENT RIGHTS in order to develop, make, use, sell or import any LICENSED PRODUCT (explicitly excluding, without limitation, any third party patents and patent
applications for formulation, stabilization and delivery), then COMPANY is allowed to deduct [***] of any additional running royalties to be paid to such third party up to [***] of the running royalties stated in Section 5.2, from
the date COMPANY has to pay running royalties to such third party. However, the running royalties stated in Section 5.2 shall not be reduced to less than a minimum of [***] of NET SALES in any case. 

For avoidance of doubt, if COMPANY or a SUBLICENSEE takes a license to a third party target, COMPANY is in no event allowed to deduct any license fees for
such target from running royalties due to [***] under this Agreement.” 
 Because Alnylam’s right to reduce its royalty obligations to
[***] pursuant to the foregoing royalty stacking provision is not co-extensive with Isis’ right to reduce its royalty obligations to Alnylam pursuant to Section 8.2 of this Agreement, Isis’ right to reduce its royalty
obligations to Alnylam pursuant to Section 8.2 of this Agreement is limited, pursuant to Section 8.2(c) of this Agreement, to the extent necessary to ensure that Isis’ royalty obligations to Alnylam are never less than Alnylam’s
royalty obligations to [***] with respect to sales by Isis, its Affiliates and its sublicensees of any Isis Product.
