In the event of either clause (ii) or (iii) above, the R&D Collaboration will not commence, the remainder of this Article 3 and all references to the R&D Collaboration in this Agreement will not apply, and Roche will receive no rights or licenses under Selected Target Products.

3.2 Selected Target Nomination

Roche may nominate prior to the Target Nomination Deadline [* * *] initial Selected Targets (or up to five (5) total Selected Targets as permitted under this Agreement) by utilizing the Gatekeeper Process designated as “Target Nomination”, with up to [* * *] of the Selected Targets being Host Cell Factor Targets. Roche may replace up to [* * *] of the Selected Targets with a Reserved Target once utilizing the replacement processes described in Section 3.6, where up to [* * *] of the Reserved Targets may be Host Cell Factor Targets.

3.3 Scope

During the R&D Collaboration Term, Roche and Dicerna shall conduct a mutually agreed discovery, research and pre-clinical development collaboration (prior to Development) for HBV disease therapies (the “R&D Collaboration”) with the goal of advancing lead candidates from each of Dicerna’s and Roche’s proprietary technology platforms Directed To the Selected Targets from which one or more Additional Dicerna Compounds and/or Roche Compounds may be generated and advanced into Development and eventually translated into Products for Commercialization by Roche. The activities conducted in connection with the R&D Collaboration will be pursuant to individual Research Plans and will be overseen by the JRC. The Parties shall not work on more than [* * *] Selected Target Research Plans at a given time without the written agreement of both Parties (which may include approved JRC minutes). For avoidance of doubt, if the Parties (or JRC) agree to suspend activities on a given Selected Target Research Plan, it shall not count as one of such [* * *].

3.4 Research Plans

Each Research Plan will outline the program and the work by the Parties to discover, research and pre-clinically develop (prior to Development) Additional Dicerna Compounds and Roche Compounds Directed To the applicable Selected Target up to the point of Clinical Candidate selection, as such plans may be updated from time to time as provided in this Agreement. Each Research Plan shall also include the plans for Roche at its own expense to either initiate or further pre-clinically develop (prior to Development) existing Roche Compounds Directed To the applicable Selected Target. Unless decided otherwise by the JRC, the Research Plan for each Selected Target will be updated annually by the JRC. Any changes shall be reflected in written amendments to the Research Plans approved by the JRC. Each Research Plan will set forth: (i) the scope of the R&D Collaboration for the applicable Selected Target broken down by activities for Dicerna Compounds and Roche Compounds, as applicable, and the resources that each Party will dedicate to the activities contemplated within the scope of the R&D Collaboration for such Dicerna Compounds and Roche Compounds, respectively; and (ii) specific objectives for each year, which objectives will be updated or amended, as appropriate, by the JRC as research progresses and based on the applicable criteria for selection of a Clinical Candidate. While each of the Dicerna and Roche teams shall primarily focus on the further research of compounds derived from their respective proprietary platforms, certain activities leveraging unique capabilities and expertise of a given Party may be applied to the Compounds generated by the other Party.

3.5 Information Exchange

3.5.1 Progress Reports

It is expected that the Research Plans shall be conducted as a joint team under the supervision of the JRC. Unless otherwise stated in the applicable Research Plan, each Party will only share data, information, results and output from in vitro and in vivo studies prior to the time a Compound is selected by the JRC to progress to non-human primate studies. After such time , Dicerna shall provide Roche with the chemistry and sequence information on the GalXC Molecule. Unless the JRC determines otherwise, on at least a Calendar Quarter basis during the R&D Collaboration Term, each Party shall prepare and provide to the JRC a detailed written report consistent with each Party’s internal practices summarizing the progress of the work performed by each Party in the course of the R&D Collaboration during the preceding Calendar Quarter, and each Party will provide a final report to the JRC at the end of a given Research Plan with respect to its activities under the Research Plan.

3.5.2 Research Records

Each Party shall maintain records of the R&D Collaboration (or cause such records to be maintained) consistent with such Party’s internal practices that each Party determines in good faith records in sufficient detail and in good scientific manner the work done and results achieved by or on behalf of such Party in the performance of the R&D Collaboration. All laboratory notebooks shall be maintained for no less than is reasonably necessary to comply with Applicable Law or the term of any Patent Rights issuing therefrom.

3.6 Replacement and Reserved Targets

Roche may only replace Selected Targets with a Reserved Target no more than [* * *] times during the R&D Collaboration Term, as provided in this Section 3.6 and in Section 3.7 below. During the Target Term for a Selected Target, if no Compounds Directed To such Selected Target are generated that meet the criteria for Clinical Candidate selection by the JRC as set forth in the applicable Research

Plan for such Selected Target and Roche requests in writing to replace such Selected Target with a Reserved Target, then such Reserved Target shall be deemed a Selected Target in place of such prior Selected Target (and no longer a Reserved Target) and the JRC shall develop a Research Plan for such replacement Selected Target no later than [* * *] after Roche’s written request for replacement.

3.7 Gatekeeper Process

From the Effective Date until the end of the Target Nomination Deadline or last Target Term, whichever is later, Dicerna will keep Roche informed of the identity and contact information for the Gatekeeper. The Parties agree the initial Gatekeeper will [* * *]. The Parties will enter into a customary confidentiality agreement that includes confidentiality at least as stringent as the provisions set forth in Article 19 and prohibits the Gatekeeper from disclosing to Roche the Not Available Targets or from disclosing to either Dicerna or Roche the identity of a target that was the subject of inquiry by the other Party.

At the Effective Date, the Gatekeeper will have a list of Not Available Targets and from time to time thereafter (including at least [* * *] per Calendar Quarter, including in response to inquiries hereunder), Dicerna will provide the Gatekeeper with an update to the list of Not Available Targets, together with any applicable rights Dicerna can still grant hereunder with respect to such Not Available Targets, and any associated restrictions.

At the Effective Date, the Gatekeeper has confirmed [* * *] Host Cell Factor Target as a Reserved Target by letter dated October 28, 2019 (“Pre-Reserved Target”). Notwithstanding anything in this Agreement, including the right to select [* * *] initial Selected Targets under Section 3.2 such Pre-Reserved Target shall remain a Reserved Target until such time as Roche in its discretion nominates it as a Selected Target.

The following are the Gatekeeper Processes to be followed with respect to target nomination (for Selected Targets) or for target nomination (for Reserved Targets), subject to the restrictions in Sections 1.136 and 1.127.

(a) [* * *].

(b) [* * *].

(c) [* * *].

(d) [* * *].

3.8 Compound Progression

Subject to JRC decisions to the contrary, Research Plan activities for each Selected Target shall continue until the selection of a Clinical Candidate from the overall pool of Roche Compounds and Additional Dicerna Compounds on a Selected Target-by-Selected Target basis. The periodic review by the JRC of the results of the Research Plans will inform which Compounds to further advance and whether to terminate development of certain Compounds and/or a Selected Target through appropriate amendments to the Research Plans. The JRC shall decide which Compound(s) will be advanced into Development to be conducted and funded by Roche with all remaining Compounds Directed To such Selected Target being reserved by Roche as backup Compounds and included within the licenses granted to Roche under Section 2.2.

During the Target Term, the JRC will make plans for the eventual Selected Target Transfer Activities with respect to Additional Dicerna Compounds (and if applicable, Roche Compounds) to Roche to enable Roche to timely continue advancement of Additional Dicerna Compounds, which Selected Target Transfer Activities will be conducted pursuant to a Selected Target Transfer Plan approved by the JSC and as otherwise reasonably requested by Roche. Selected Target Transfer Activities set forth in the given Selected Target Transfer Plan will be provided by or on behalf of Dicerna free of charge. For additional Selected Target Transfer Activities reasonably requested by Roche not set forth in the given Selected Target Transfer Plan, Dicerna shall provide up to [* * *] free of charge. Thereafter, additional hours will be provided at Roche’s expense based on Dicerna’s then current FTE Rate and Roche will reimburse Dicerna for all of Dicerna’s reasonable out of pocket expenses incurred in connection therewith.

If the JRC fails to select a Clinical Candidate for a given Selected Target prior to the expiration of the Target Term, Roche will either terminate its rights to Licensed Products under Section 20.2.5 (and such Selected Target will become a Discontinued Target) or will notify Dicerna of its intention (“Roche Continuation Notice”) to proceed with the further research and development of Licensed Products for such Selected Target in which case the JRC will promptly implement the associated Selected Target Transfer Plan. If Roche has provided a Roche Continuation Notice and fails to progress a Clinical Candidate Directed To such Selected Target within [* * *], then Roche must terminate such Selected Target under Section 20.2.5 (and such Selected Target will become a Discontinued Target).

3.9 Exclusivity

During the Exclusivity Period:

(a) Dicerna will collaborate exclusively with Roche in the discovery, research, and development of GalXC Molecules Directed To Selected Targets in the Limited Field or if cleared pursuant to Section 3.7 the Field during the R&D Collaboration, other than as may be incidental to research activities outside the scope of this Agreement.

(b) [* * *].

3.10 Research Plan Costs of Performance

Other than Dicerna’s development responsibilities listed in Section 6.1, Roche, at its sole cost and discretion (subject to Article 4 and subject to discretion limitations and cost sharing under Dicerna’s Cost Share Option), shall be responsible for pursuing Development of Products.

Roche shall maintain records of its Development activities (or cause such records to be maintained) consistent with its internal practices. Roche shall be responsible for the correct use of Dicerna PII/Samples in line with Applicable Law and the informed consent forms. Notwithstanding anything to the contrary in this Agreement but subject to Section 6.1 above (and except with respect to the Lead Compound and Lead Product if Dicerna exercises its Cost Share Option), Dicerna will not bear any costs or expenses in connection with Development of Compounds or Products.

6.3 Dicerna Cost Share Option

Dicerna shall have the option (the “Cost Share Option”) (unless earlier waived in accordance with this Section) to share in Development Costs and thereby receive increased royalties in the US for the Shared Products as described in this Agreement (the “Cost Share Right”). For so long as Dicerna has the Cost Share Option, Roche will provide to Dicerna through the JRC the current Development Plan and any updates and amendments thereto.

6.3.1 Option and Exercise

6.3.1.1 Roche Provision of Cost Share Package

Unless Dicerna earlier waives its Cost Share Option in writing, no later than at such time as Roche formally decides (based on Roche’s then current internal governance decision-making process and committees) to proceed into the first Pivotal Study for the Lead Product (or a Hybrid Product, as applicable), Roche shall provide to Dicerna a package (“Cost Share Package”) including (i) relevant data from the previous Clinical Studies conducted by or on behalf of Roche, if not already shared, (ii) an accounting of Roche’s actual Development Costs up to and including the previous Calendar Quarter, (iii) a copy of Roche’s then-existing proposed Development Plan for the Lead Product or Hybrid Product and (iv) for informational purposes only, Roche’s good faith, non-binding forecast, made in accordance with its regular internal forecasting procedures, of all then planned project

Development Costs consistent with the Development Plan for the Lead Product or Hybrid Product (for clarity, the information that Roche provides to its internal decision-making committee for the purposes of deciding whether to proceed into the first Pivotal Study). Dicerna may ask reasonable questions concerning the contents of the Cost Share Package through the JRC and Roche will make appropriate representatives available to provide answers to Dicerna’s questions.

6.3.1.2 Cost Share Option Exercise

Dicerna may exercise its Cost Share Option by providing written notice at any time within [* * *] of Dicerna’s receipt of the Cost Share Package. In the event that at the time Roche provides Dicerna with the Cost Share Package, Roche’s internal governance decision-making committee has not yet decided to proceed into the first Pivotal Study for the Lead Product, then such exercise by Dicerna shall not be effective unless, within the [* * *] after such exercise, Roche notifies Dicerna that such internal governance committee decision has been made and (a) such decision is consistent with the plan furnished to Dicerna in the Cost Share Package, and (b) Roche notifies Dicerna of any updates or changes to the Cost Share Package, including any deviations from the Development Plan. If such decision is then made by Roche but changes the plan furnished to Dicerna in the Cost Share Package, Roche shall revise the Cost Share Package and deliver it to Dicerna. Dicerna may then exercise its Cost Share Option by providing written notice at any time during the period commencing upon Dicerna’s receipt of the revised Cost Share Package and ending thirty (30) days later. Commencing upon Dicerna’s exercise of its Cost Share Option and continuing until the end of the Royalty Term unless and until Dicerna fails to meet its obligations under Section 6.3.2, (i) Dicerna shall have the Cost Share Right and (ii) any Lead Product shall also be deemed as a “Shared Product”. Provided that Dicerna exercises its Cost Share Option for the Lead Product, Dicerna shall also be granted a Cost Share Option for each subsequent Hybrid Product. The foregoing option exercise procedure for the Lead Product shall also be applied for eligible Hybrid Products. Any Hybrid Product for which Dicerna exercises its Cost Share Option shall be deemed a Shared Product.

6.3.2 Payments to Roche

If Dicerna exercises its Cost Share Option, then Dicerna will be responsible for [* * *] as follows:

(a) Dicerna will pay Roche [* * *] of Roche’s actual global Development Costs up to and including the last Calendar Quarter prior to Dicerna’s exercise of the Cost Share Option (the “Initial Cost Share Payment”). Within [* * *] of Dicerna’s receipt of an invoice from Roche, Dicerna may notify Roche in writing of its election to set off the Initial Cost Share Payment against the payment from Roche to Dicerna for the Initiation of a Pivotal Study under Section 11.2.1, up to the full amount of the Initial Cost Share Payment. To the extent the Initial Cost Share Payment will not be set off against the Initiation of a Pivotal Study payment under Section 11.2.1, Dicerna will pay Roche such amount within [* * *] of Dicerna’s receipt of an invoice from Roche.

(b) For such time as there are forecasted Development Costs, Roche shall in accordance with its regular internal forecasting processes and annual forecast cycle, provide Dicerna its forecast of all then planned project Development Costs for Shared Product(s), including the forecasted budget for a given Calendar Year (“Annual Budget”) in final form within [* * *]. For such time as there are Shared Product(s), Roche shall (a) within [* * *], give Dicerna preliminary actual Development Costs for such Shared Product(s) for such Calendar Quarter and in the event of material changes, an updated Annual Budget for the remainder of the Calendar Year and (b) within [* * *], give Dicerna the final actual Development Costs for such Shared Product(s) for such Calendar Quarter.

(c) For each Calendar Quarter (including the Calendar Quarter in which Dicerna exercised its Cost Share Option), within [* * *] after Dicerna’s receipt of an invoice from Roche, Dicerna will make a payment to Roche for (i) with respect to Lead Products, [* * *] of Roche’s actual Development Costs for the applicable previous [* * *] or (ii) with respect to Hybrid Products, [* * *] of Roche’s actual Development Costs for the applicable previous [* * *].

(d) In the event that actual Development Costs for a Calendar Year exceed the Annual Budget, including due to Extraordinary Events, by more than [* * *], Dicerna’s portion of any such excess Development Costs be deferred and payable to Roche in subsequent Calendar Years, with a maximum amount of such excess payable by Dicerna in a [* * *] not to exceed US dollars [* * *]. For the avoidance of doubt, the maximum amount of Development Costs to be paid by Dicerna after the end of a Calendar Year (but subject to additional deferred payments by Dicerna) shall be [* * *] of Dicerna’s portion of the Annual Budget. By way of example, if the Annual Budget for the year 2022 is [* * *] with Dicerna’s portion thereof equaling [* * *] and the FDA requires an additional arm be included in a Pivotal Study with the estimated costs for Calendar Year 2022 for such additional arm equaling [* * *] and actual Development Costs incurred by Roche for Calendar Year 2022 (including the additional arm) total [* * *] then Dicerna’s total Development Costs payable to Roche shall [* * *] of which [* * *] shall be payable by Dicerna within [* * *] after the end of 2022 and the remaining [* * *] shall be deferred and payable in [* * *] equal installments of [* * *] each after the end of [* * *], respectively.

(e) Invoices submitted by Roche to Dicerna for Development Cost reimbursement will set forth in reasonable detail such costs and expenses to be reimbursed, which costs and expenses shall be specifically identifiable or reasonably allocable to the conduct of Shared Product Development Costs as determined in accordance with the applicable Accounting Standard, including any amounts that may be deferred into the following year.

6.3.3 Adjustment of Royalty Rate for Shared Product US Net Sales

If Dicerna exercises its Cost Share Option and maintains its Cost Share Right by payment of its portion of the Development Costs, then the royalty rate for the Shared Product shall be increased in accordance with Section 11.4.2.1.

If Dicerna exercises its Cost Share Option, then Dicerna also shall have the option (the “Co-Promotion Option”) to assume between [* * *] of the total sales force for each Shared Product measured in terms of Sales Representatives in the Co-Promotion Territory (the “Co-Promotion Right”). The Parties shall agree to a specific percentage within this range as part of the Co-Promotion Agreement. Notwithstanding the foregoing, Shared Products that are Combination Products containing an Encumbered Combination Agent are not subject to the Co-Promotion Option and Co-Promotion Right set forth herein.

10.6.2 Notice and Exercise

(a) Approximately [* * *] before the anticipated filing of the first MAA for a given Shared Product, Roche will deliver and present to and discuss with the JSC the applicable Commercialization Plan, including Roche’s preliminary estimate of the number of Sales Representatives it anticipates for such Shared Product for such launch in the Co-Promotion Territory (the “Roche Estimate”). In addition to information received through the JSC, Dicerna may submit written questions to Roche about the Commercialization Plan for such Shared Product (“Shared Product Questions”) within [* * *] of the receipt of such Roche Estimate, in which case Roche will respond to such timely-delivered questions no later than [* * *] from receipt of Dicerna’s questions (the date of such delivery of all answers, the “Roche Response Date”). Dicerna may exercise its Co-Promotion Option by giving written notice thereof to Roche no later than the end of the Co-Promotion Exercise Period, all in accordance with Section 10.6.2(b).

(b) As conditions precedent to exercising a Co-Promotion Option for a Shared Product and maintaining the Co-Promotion Right for such Co-Promotion Product, Dicerna must:

(i) establish, by means of a presentation to Roche as of the time of exercise, that it has (A) an already established internal sales management organization and infrastructure to conduct Dicerna’s Co-Promotion activities for such Co-Promotion Product and (B) a plan to hire, retain or otherwise build a sales force consisting of direct employees of Dicerna that will be in place no later than [* * *] after the First Commercial Sale of such Co-Promotion Product with the number of Sales Representatives that Dicerna is required to use, each of whom has prior experience promoting pharmaceutical products to prescribing physicians in the Co-Promotion Territory and meets the qualifications set forth in Appendix 10.6.3; and

(ii) as of the time of exercise, and for so long as Dicerna is Co-Promoting such Co-Promotion Product hereunder and under the Co-Promotion Agreement, not be developing or commercializing by itself or in collaboration with a Third Party, either (A) another product that treats HBV or that (B) is an Encumbered Combination Agent.

(c) If Dicerna does not provide the election notice described in Section 10.6.2(a) prior to expiration of the applicable Co-Promotion Exercise Period or if Dicerna does not meet the requirements set forth in Section 10.6.2(b), Dicerna shall be deemed to have irrevocably waived its right to Co-Promote such Shared Product. Any election notice provided by Dicerna at a time when Dicerna

does not meet the requirements set forth in Section 10.6.2(b) shall be void and have no effect. Following Dicerna’s exercise of its Co-Promotion with respect to a particular Co-Promotion Product, if that Co-Promotion Product subsequently attains Regulatory Approval in an Encumbered Combination Indication, Dicerna shall not engage in the Detailing or other Co-Promotion Activities for the Co-Promotion Product in the Encumbered Combination Indication, except as provided for in the Co-Promotion Agreement. If Dicerna does not exercise its Co-Promotion Option (or if it has been deemed to have waived its Co-Promote Right pursuant to this Section 10.6.2(c)) for a given Shared Product for the First Eligible Co-Promotion Indication, Dicerna shall not have the right to exercise its Co-Promotion Option with respect to any subsequent Regulatory Approvals or label expansion granted for such Shared Product. As used in this Section 10.6.2(c), the “First Eligible Co-Promotion Indication” for a Co-Promotion Product is the first indication for which Regulatory Approval in the Co-Promotion Territory is obtained that is not an Encumbered Combination Indication.

10.6.3 Co-Promotion Agreement

Promptly after Dicerna’s first exercise of a Co-Promotion Option for a Co-Promotion Product, and subject to Dicerna’s compliance with the requirements of Section 10.6.2(b)(b), the Parties shall negotiate in good faith and enter into a written agreement for Co-Promotion (the “Co-Promotion Agreement”) setting forth the terms of Dicerna’s and Roche’s Co-Promotion rights and obligations (including the specific percentage of the total sales force in the range permitted under Section 10.6.1) with regard to such Co-Promotion Product in accordance with the terms and conditions in this Agreement (including this Article 10, including Sections 10.6.2(b)(b), 10.6.4 and 10.6.5, and those set forth in Appendix 10.6.3). The Parties shall negotiate with such diligence as is required to enter into and execute the Co-Promotion Agreement within [* * *] following such exercise, or such other date as the Parties may agree in writing. The Parties shall promptly amend the Co-Promotion Agreement upon each subsequent exercise by Dicerna of a Co-Promotion Option with regard to a new Shared Product in accordance with the terms and conditions in this Article 10 and Appendix 10.6.3. In addition to any other terms agreed to by the Parties, the Co-Promotion Agreement shall contain the terms set forth in Appendix 10.6.3 of this Agreement. Unless otherwise agreed to by the Parties, Dicerna may not commence Co-Promotion on Co-Promotion Products until such time as the Parties enter into the Co-Promotion Agreement.

10.6.4 General Requirements for Co-Promotion Activities

Dicerna’s Co-Promotion Rights shall only exist during such time as Dicerna has the Cost Share Right.

Dicerna may not use contract sales forces to fulfill its Co-Promote obligations for more than [* * *] after the First Commercial Sale of the first Co-Promotional Product. Any Dicerna Sales Representatives involved in a sales call for one or more Co-Promotion Product(s) shall devote at least [* * *] of its sales call time until the [* * *] anniversary of First Commercial Sale in the US and thereafter at least [* * *] of such call time to the Co-Promotion Product(s). Under the Co-Promotion Agreement, Roche shall have the sole right to control all decisions with respect to the co-promotion arrangement, including the call plans and assigned territories of Dicerna Sales Representatives, the promotional materials to be used, the training and testing applicable to such Sales Representatives, and restrictions with respect to the ability of such Sales Representatives to Detail other products. “Co-Promote”, “Co-Promoting” or “Co-Promotion” means the US Detailing activities assigned to Dicerna in the Co-Promotion Agreement, and shall not include any Medical Affairs Activities, sale or distribution of such Co-Promotion Product in the Co-Promotion Territory by Dicerna or its Affiliates. Dicerna shall have the right to terminate its Co-Promotion Rights for a Co-Promotion Product with [* * *] prior written notice

to Roche, in which case, the Parties shall reasonably cooperate to transition to Roche, upon the effective date of such termination, all of Dicerna’s Co-Promotion activities to such Co-Promotion Product so as to minimize disruption to sales activity, the details of which shall be further set forth in the Co-Promotion Agreement.

10.6.5 Change of Control

Section 20.2.3 shall apply in the event of a Dicerna Change of Control.

10.7 Medical Affairs

Roche shall have the sole right and responsibility to conduct and make decisions regarding Medical Affairs Activities with respect to any Product. For clarity, Roche shall retain such sole right and responsibility in the event that Dicerna exercises its Co-Promotion Option. For further clarity, Dicerna’s Sales Representatives shall be supported by Roche’s Medical Affairs personnel.

Each development event payment shall be paid only once, the first time the first Lead Product reaches the applicable triggering event, regardless the number of times such events are reached and by how many Lead Products. [* * *].

For the avoidance of doubt, development event payments due on a Lead Product under this Section 11.2.1 shall continue to be due at the rate applicable to Lead Products (not Hybrid Products) until the applicable Lead Product has achieved its First Commercial Sale in such jurisdiction as a product not containing a Selected Target Compound.

11.2.2 Selected Target Products and Hybrid Products

If any of events 5 through 7 above are achieved by a Selected Target Product, any of events 1 through 4 not previously achieved by such Selected Target Product shall be deemed to have been achieved at the time of achievement of events 5 through 7, as applicable, and the corresponding milestone payment shall be owed.

11.2.3 Development and Regulatory Event Payment Invoicing and Timing

Upon occurrence of each development and regulatory event in this Section 11.2, Roche shall notify Dicerna within [* * *] of the event and pay the corresponding development and regulatory event payment to Dicerna within [* * *] of the event and receipt of an invoice from Dicerna. Each such payment shall be non-refundable and non-creditable.

11.4.4 Combination Product

If Roche or its Affiliates intend to sell a Combination Product, then the Parties shall meet approximately [* * *] prior to the anticipated First Commercial Sale of such Combination Product in the Territory to negotiate in good faith and agree to an appropriate adjustment to Net Sales to reflect the relative commercial value contributed by the components of the Combination Product (the “Relative Commercial Value”). If, after such good faith negotiations not to exceed [* * *], the Parties cannot agree to an appropriate adjustment, the dispute shall be initially referred to the executive officers of the Parties in accordance with Section 22.2.

If the Parties are unable to agree on the Relative Commercial Value within [* * *] of such referral, then the Relative Commercial Value shall be determined by the following procedure. Roche will select one (1) individual who would qualify as an Expert, Dicerna will select (1) individual who would qualify as an Expert, and those two (2) individuals shall select one (1) individual who would qualify as an Expert and who shall be chairman of a committee of the three Experts (the “Expert Committee”), each with a single deciding vote. The Expert Committee will promptly hold a meeting to review the issue under review, at which it will consider memoranda submitted by each Party at least [* * *] before the meeting, as well as reasonable presentations that each Party may present at the meeting. As part of the Expert Committee’s consideration, the Parties agree that the Relative Commercial Value of the Lead Product within a Combination Product shall not be less than (a) [* * *] if the first Filing for Regulatory Approval is (or is planned to be, as applicable) for use with one additional Non-Compound Active Agent Controlled by Roche where such compound has a Valid Claim of the composition of matter with at least [* * *]remaining patent life in one or more countries in the Territory or (b) [* * *] if the condition in part (a) is not met. The determination of the Expert Committee as to the issue under review will be binding on both Parties. The Parties will share equally in the costs of the Expert Committee. Unless otherwise agreed to by the Parties, the Expert Committee may not decide on issues outside the scope mandated under terms of this Agreement.

A Hybrid Product shall not be treated as a Combination Product under this Section 11.4.4 with respect to the Lead Compound and Selected Target Compound, however the Relative Commercial Value will be determined if there are other Combination Product components other than the Lead Compound and Selected Target Compound.

11.4.5 No Composition of Matter Claim or Regulatory Exclusivity; Generic Competition

For a given Product, and subject to Section 11.4.7, if in a given country within the Territory there is:

(a) no Composition of Matter Claim of a Party that Covers such Product and no applicable Regulatory Exclusivity for such Product remains in such country; or

(b) entry of a Like-Substance Product has occurred, provided that after such entry there has been a decline of quarterly Net Sales of such Product in such country greater than [* * *] of the average level of the quarterly Net Sales of such Product achieved in the [* * *] immediately prior to such entry;

then the royalty payments due to Dicerna for such Product in such country shall be reduced for the remainder of the Royalty Term by (i) [* * *] for the Major Markets other than [* * *], or (ii) [* * *].

11.4.6 Third Party Payments

Other than for the Existing Third Party In-License Agreement listed in Appendix 16.1.5 (for which Dicerna shall be responsible), Roche shall be responsible for and pay or have paid any consideration owed to any Third Party in relation to Third Party intellectual property rights necessary or useful to make, use or sell Products. With respect to such Third Party Patent Rights that are reasonably necessary for the sale of a given Product in a given country, Roche shall have the right to deduct (x) a maximum of [* * *] of royalties actually paid by Roche to such Third Party with respect to such arrangement from (y) royalty payments otherwise due and payable by Roche to Dicerna for such Product in such country under this Agreement. Any such deduction shall be made only on a Product-by-Product and country-by-country basis. Prior to entering into such arrangement, Roche will notify and discuss with Dicerna unless Roche will not deduct payments under such arrangement.

11.4.7 Maximum Deductions

In no event shall the royalty paid to Dicerna for Net Sales of Products hereunder, as reduced by Sections 11.4.5 and 11.4.6, be reduced from the applicable royalty rates set forth in Section 11.4.2 above by more than an amount equal to (i) [* * *] of the royalties otherwise due for Net Sales of such Products for the Major Markets other than [* * *], or (ii)  [* * *].

Compulsory Sublicense Compensation received by the Roche Group from a Compulsory Sublicensee during the Royalty Term shall be shared with Dicerna on an equivalent profit share percentage (the “Compulsory Profit Share Percentage”) calculated for the respective Calendar Year for the relevant country as follows:

[* * *]	[* * *]
	[* * *]

At the end of the Calendar Year, Roche shall pay to Dicerna the Compulsory Sublicense Compensation under a given country multiplied by the Compulsory Profit Share Percentage for such country. For clarity, any sales or payments by Compulsory Sublicensees under a Compulsory Sublicense shall not be considered as Net Sales and shall not give rise to any royalty payment under Section 11.4.2 of this Agreement.

(a) Dicerna will have the right to receive the applicable royalties of Net Sales in such country in local currency by deposit in a local bank designated by Dicerna, or

(b) if such local currency payment is not allowed by reason of Applicable Law or if otherwise requested by Dicerna, then the royalties related to such Net Sales in such country shall continue to be accrued and shall continue to be reported, but such royalties will not be paid until the sales proceeds related to such Net Sales may be removed from such country. At such time as Roche, its Affiliates or their Sublicensees, as the case may be, is able to remove the sales proceeds related to such Net Sales from such country, Roche shall also pay such accrued royalties in Payment Currency using the actual exchange rate which is used to remove such sales proceeds from such country.

Notwithstanding anything in this Agreement to the contrary, if Roche’s assignment of this Agreement leads to the imposition of income tax liability on Dicerna that would not have been imposed in the absence of such action or in an increase in such liability above the liability that would have been imposed in the absence of such action, Roche will indemnify and hold harmless Dicerna from any such additional or increased income tax liability (except to the extent that Dicerna or any of its Affiliates can obtain a refund or credit for such amounts, provided that Dicerna will be reimbursed for any reasonable out of pocket costs incurred in obtaining such a refund or credit).

The Parties shall cooperate and exercise their reasonable best efforts to ensure that any such withholding taxes are mitigated or reduced to the extent possible under the provisions of any Applicable Law, and shall provide the Payee reasonable assistance (including the provision of any tax forms and other information) in order to allow the Payee to obtain the benefit of any present or future treaty against double taxation or exemption from, refund or reduction in taxes which may apply to such payments.

14.1 Dicerna Right to Audit

Roche shall keep, and shall require its Affiliates and Sublicensees to keep, full, true and accurate books of account containing all particulars that may be necessary for the purpose of calculating all royalties payable under this Agreement. Such books of accounts shall be kept at their principal place of business. At the expense of Dicerna, Dicerna shall have the right to engage an internationally recognized independent public accountant reasonably acceptable to Roche to perform, on behalf of Dicerna, an audit of such books and records of Roche and its Affiliates and Sublicensees that are deemed necessary by the independent public accountant to report on Net Sales of Product for the period or periods requested by Dicerna and the correctness of any financial report or payments made under this Agreement.

Upon timely request and at least [* * *] prior written notice from Dicerna, such audit shall be conducted for those countries Dicerna has specifically requested, during regular business hours in such a manner as to not unnecessarily interfere with Roche's normal business activities. Such audit shall be limited to results in the [* * *] prior to audit notification, and if Dicerna requests an audit for a given Calendar Year, no additional audits may be conducted for such Calendar Year, unless such audit is for cause based on a material finding identified in the initial annual audit.

Other than GalXC Platform Improvements and Roche Background Improvements, Dicerna shall own all Dicerna Inventions, Roche shall own all Roche Inventions, and Dicerna and Roche shall jointly own all Joint Inventions. Dicerna and Roche each shall require all of its employees to assign all Inventions made by them to Roche and Dicerna, as the case may be.

The determination of inventorship for Inventions shall be in accordance with US inventorship laws as if such Inventions were made in the US.

Subject to the licenses granted under this Agreement, Dicerna and Roche will each have an equal undivided share in the Joint Patent Rights, without obligation to account to the other for exploitation thereof, or to seek consent of the other Party for the grant of any license thereunder.

Except as specifically set forth herein, this Agreement shall not be construed as: (i) giving any of the Parties any license, right, title, interest in or ownership to (a) the Confidential Information of the other Party or (b) any materials, Know-How, Patent Rights or other intellectual property rights Controlled by the other Party or its Affiliates; (ii) granting any license or right under any intellectual property rights; or (iii) representing any commitment by either Party to enter into any additional agreement, by implication or otherwise.

The Indemnified Party shall cooperate with the Indemnifying Party and may, at its option and expense, be represented in any such action or proceeding by counsel of its choice. The Indemnifying Party shall not be liable for any litigation costs or expenses incurred by the Indemnified Party without the Indemnifying Party’s written consent.

18. Liability

18.1 Limitation of Liability

Subject to the Parties’ obligations hereunder to use Commercially Reasonable Efforts including in Article 4 (Diligence), neither Party shall be liable to the other Party as a result of failure or delay to develop and/or commercialize the Compound or the Product, as applicable, including a) a delay in timelines, or b) delay or failure to recruit patients, or c) a change in its respective study protocols, or d) failure to obtain regulatory approval for the Compound or the Product, as applicable.

19. Obligation Not to Disclose Confidential Information

19.1 Non-Use and Non-Disclosure

During the Agreement Term and for [* * *] thereafter, a Receiving Party shall (i) treat Confidential Information provided by Disclosing Party as it would treat its own information of a similar nature, (ii) take all reasonable precautions not to disclose such Confidential Information to Third Parties, without the Disclosing Party’s prior written consent, and (iii) not use such Confidential Information other than for fulfilling its obligations and exercising its rights under this Agreement.

19.2 Permitted Disclosure

Notwithstanding the obligation of non-use and non-disclosure set forth in Section 19.1, the Parties recognize the need for certain exceptions to this obligation, specifically set forth below, with respect to press releases, patent rights, publications, securities law requirements, and certain commercial considerations.

19.3 Press Releases

The Parties may issue a press release announcing the existence and selected key terms of this Agreement, in a form substantially similar to the template attached as Appendix 18.3 of this Agreement.

Roche may issue press releases in accordance with its internal policy that typically does not issue a second press release until proof of concept has been achieved for a Compound. Roche shall provide Dicerna with a copy of any draft press release related to the activities contemplated by this Agreement at least [* * *] prior to its intended publication for Dicerna's review. Dicerna may provide Roche with suggested modifications to the draft press release. Roche shall in good faith consider Dicerna's suggestions prior to issuing its press release.

Dicerna shall only issue press releases related to the activities contemplated by this Agreement that either (i) have been approved by Roche or (ii) are required to be issued by Dicerna as a matter of law and Dicerna has been advised by counsel to that effect. In all circumstances, Dicerna shall endeavor to provide Roche with a draft press release at least [* * *] prior to its intended publication (or as soon as practicable with good faith) for Roche's review. During such period, Roche shall (i) approve the draft press release and permit Dicerna to issue the press release, (ii) contact Dicerna to discuss modification to the draft press release, or (iii) contact Dicerna and disapprove the press release. If Roche asks for modification, then Dicerna shall either make such modification or work with Roche to arrive at a press release that Roche approves. If Dicerna issues a press release without Roche's

approval, then such release must be made by Dicerna in consultation with counsel that the release was required to be issued by Dicerna as a matter of law.

To ensure communication alignment, responses (if any) to inquiries by media or other Third Parties after issuance of a permitted press release by Dicerna (solely or jointly with Roche) shall consist solely of the press release language or shall follow the response guidelines that may be mutually developed by the Parties (or as deemed necessary by Dicerna’s counsel).

19.4 Publications

During the Agreement Term, the following restrictions shall apply with respect to disclosure by any Party of Confidential Information relating to the Product in any scientific publication or presentation (provided that, for avoidance of doubt, such restrictions shall not apply to information contained in patent applications):

(a) Both Parties acknowledge that it is their policy for studies and results thereof to be registered and published in accordance with their internal guidelines. Roche, in accordance with its internal policies and procedures, shall have the right to publish all studies, clinical trials and results thereof on the clinical trial registries that are maintained by or on behalf of Roche. Other than with respect to the Dicerna Phase I Study, Dicerna shall not publish any studies, clinical trials or results thereof on its clinical trial registry, provided however, that Roche’s clinical trial registry can be accessed via a link from Dicerna’s clinical trial registry.

(b) Dicerna may not publish such information about Licensed Products without the prior written consent of Roche.

19.5 Commercial Considerations

(a) Nothing in this Agreement shall prevent Dicerna or its Affiliates from disclosing Confidential Information of Roche to (i) Third Parties acting on behalf of Dicerna, to the extent reasonably necessary and as permitted for the development, manufacture or Co-Promotion of Lead Product in the Territory, (ii) Third Parties requesting Dicerna Phase I Study clinical trial data information (in accordance with Dicerna’s then-current data sharing policy), or (iii) actual and potential partners and investors subject to commercially reasonable confidentiality obligations.

(b) Nothing in this Agreement shall prevent Roche or its Affiliates from disclosing Confidential Information of Dicerna to (i) governmental agencies to the extent required or desirable to secure government approval for the development, manufacture or sale of Product in the Territory, (ii) Third Parties acting on behalf of Roche, to the extent reasonably necessary for the development, manufacture or sale of Product in the Territory, (iii) Third Parties requesting clinical trial data information (in accordance with the applicable Party’s then-current data sharing policy), (iv) Third Parties to the extent reasonably necessary to market the Product in the Territory, or (iv) actual and potential partners and investors subject to commercially reasonable confidentiality obligations.

(c) The Receiving Party may disclose Confidential Information of the Disclosing Party to the extent that such Confidential Information is required to be disclosed by the Receiving Party to comply with Applicable Law, to defend or prosecute litigation or to comply with governmental regulations, provided that the Receiving Party provides prior written notice of such disclosure to the Disclosing Party and, to the extent practicable, takes reasonable and lawful actions to minimize the degree of such disclosure.

(d) The Parties acknowledge that either or both Parties may be obligated to make one or more filings (including to file a copy of this Agreement) with the U.S. Securities and Exchange Commission

(or equivalent foreign agency) or a governmental authority. Each Party will be entitled to make such a required filing, provided that if such filing includes a copy of this Agreement it will (i) submit in connection with such filing a copy of this Agreement in a form mutually agreed by the Parties in advance or, if despite the reasonable efforts of Dicerna a form mutually agreed by the Parties cannot be agreed in advance, redacted to the extent permitted by Applicable Law (the “Redacted Agreement”), (ii) request, and use reasonable efforts consistent with Applicable Laws to obtain, confidential treatment of all terms redacted from this Agreement, as reflected in the Redacted Agreement, for a period of at least [* * *], (iii) to the extent consistent with Applicable Law, promptly deliver to the other Party any written correspondence received by it or its representatives from the U.S. Securities and Exchange Commission (or equivalent foreign agency) or a governmental authority with respect to such confidential treatment request and promptly advise the other Party of any other material communications between it or its representatives with the U.S. Securities and Exchange Commission (or equivalent foreign agency) or a governmental authority with respect to such confidential treatment request, (iv) upon the written request of the other Party, if legally justifiable, request an appropriate extension of the term of the confidential treatment period, and (v) if the U.S. Securities and Exchange Commission (or equivalent foreign agency) or a governmental authority requests any changes to the redactions set forth in the Redacted Agreement, use reasonable efforts consistent with Applicable Laws to maintain the redactions in the Redacted Agreement as originally filed and not agree to any changes to the Redacted Agreement without, to the extent practical, first discussing such changes with the other Party and taking the other Party’s comments into consideration when deciding whether to agree to such changes (provided that a Party will only be required to make such efforts to support such redactions once). For clarity, following a request from a governmental authority to change the redactions requested by a Party, a Party will not be required pursuant to the provisions of this Section 19.5(d) to again request the redactions rejected by the applicable governmental authority. Each Party will be responsible for its own legal and other external costs in connection with any such filing, registration or notification.

19.6 Injunctive Relief

The Parties agree that a breach of Article 19 may cause irrevocable harm for which monetary damages might not provide a sufficient remedy. In case of an actual or threatened material breach of Article 19, in addition to any other remedy available under this Agreement or under applicable Laws or equity, the non-breaching Party will be entitled to seek and obtain equitable relief (including temporary or permanent restraining orders, specific performance or other injunctive relief) from any court of competent jurisdiction, without the necessity of posting any bond or of any undertaking (other than with respect to enjoining a product launch), and without any requirement to submit to any dispute resolution procedures contained herein.

20.2 Termination

20.2.1 Termination for Material Breach

After the Effective Date, a Party (“Non-Breaching Party”) shall have the right to terminate this Agreement in its entirety or on a Product-by-Product basis in the event the other Party (“Breaching

Party”) is in material breach (which shall include any breach of Section 3.9 (Exclusivity), Section 4 (Diligence) and Section 22.17 (Compliance with Laws)) of its obligations under this Agreement. The non-Breaching Party shall provide written notice to the Breaching Party, which notice shall identify the material breach. The Breaching Party shall have a period of [* * *] after such written notice is provided (“Peremptory Notice Period”) to cure such material breach. If the Breaching Party has a dispute as to whether such material breach occurred or has been cured, it will so notify the Non-Breaching Party within the Peremptory Notice Period and the Agreement shall not terminate until such dispute is resolved pursuant to Section 22.2 and 22.3. Upon a determination of material breach and failure to cure, the Breaching Party shall have the Peremptory Notice Period to cure such material breach. If such material breach is not cured within the Peremptory Notice Period, then absent withdrawal of the Non-Breaching Party’s request for termination, this Agreement shall terminate in its entirety or with respect to such Product effective as of the expiration of the Peremptory Notice Period.

20.2.2 Insolvency

Either Party shall have the right to terminate this Agreement, if the other Party incurs an Insolvency Event; provided, however, in the case of any involuntary bankruptcy proceeding, such right to terminate shall only become effective if the Party that incurs the Insolvency Event consents to the involuntary bankruptcy or such proceeding is not dismissed within [* * *] after the filing thereof.

20.2.3 Effects of Change of Control

If there is a Change of Control, then the Party experiencing such Change of Control (“Acquired Party”) shall provide written notice to the other Party (“Non-Acquired Party”) at least [* * *] prior to completion of such Change of Control, subject to any confidentiality obligations of the Acquired Party then in effect (but in any event shall notify the Non-Acquired Party within [* * *] after completion of such Change of Control).

The Change of Control Group in connection with such Change of Control shall not have the right to utilize any of the Non-Acquired Party’s Know-How (excluding information generally applicable to other products or retained in the unaided memory of Dicerna employees), Patent Rights, Inventions, Materials or Confidential Information (collectively, “Sensitive Information”) for the research, development or commercialization of any product for the treatment of any indication or patient population for which a Product may be developed or commercialized.

Following consummation of the Change of Control, the Non-Acquired Party and the Change of Control Group shall adopt in writing reasonable procedures to prevent the disclosure of Sensitive Information beyond the Acquired Party’s personnel who need to know the Sensitive Information solely for the purpose of fulfilling the Acquired Party’s obligations under this Agreement or for lawful reporting obligations. [* * *].

20.2.4 Termination by Roche without a Cause

After the Effective Date, Roche shall have the right to terminate a given Research Plan under the R&D Collaboration (i.e. on a Selected Target-by-Selected Target basis) or the R&D Collaboration in its entirety upon [* * *] prior written notice, and such Selected Target shall become a Discontinued Target.

In addition to the foregoing, at any time after the Effective Date, Roche shall have the right to terminate this Agreement as a whole or on a Licensed Product-by-Licensed Product basis upon [* * *] prior written notice before First Commercial Sale of a Licensed Product or upon [* * *] prior written notice after the First Commercial Sale of a Licensed Product. The effective date of termination under this Section 20.2.4

paragraph 2 shall be the date [* * *] as the case may be) after Roche provides such written notice to Dicerna.

20.2.5 Termination of Selected Targets

After the Effective Date, at the end of the R&D Collaboration Term (or earlier termination thereof), if across all Selected Targets Roche does not select any Additional Dicerna Compounds as a Clinical Candidate, Roche shall have the right, but not the obligation, to terminate all rights to all Additional Dicerna Compounds generated under the R&D Collaboration upon [* * *] written notice. After a Clinical Candidate is selected for a given Selected Target or after the Target Term if Roche provides a Roche Continuation Notice, Roche shall have the right to (or where required by Section 3.8, the obligation to) terminate with respect to all Licensed Products for such Selected Target upon [* * *] prior written notice. Upon such termination, such Selected Target shall become a Discontinued Target.

20.3 Consequences of Termination

20.3.1 Roche Compound License

In the event of a (i) termination of the Agreement as a whole by Roche pursuant to Section 20.2.1 (for Material Breach by Dicerna), Section 20.2.2 (for Dicerna’s Insolvency) or Section 20.2.4 (Without a Cause) or (ii) termination pursuant to Section 20.2.5 (Termination of Selected Targets) or pursuant to Section 20.2.6 (for Patent Challenge) (a “Non-Exclusive Trigger”) then

(a) Roche shall retain the Non-Exclusive Roche License for (i) all applicable Roche Compounds (for Agreement termination) or (ii) all applicable Roche Compounds Directed To the given Selected Target being terminated (for Selected Target termination),

(b) Article 4 notwithstanding, Roche shall not continue to have diligence obligations related to any such Roche Compounds, and,

(c) the financial compensation owed to Dicerna for Roche Compounds under Sections 11.2.2 and 11.4.2.2 and shall remain, but subject to the following reductions:

(i) [* * *]

(ii) [* * *]

(iii) [* * *].

[* * *].

Notwithstanding the foregoing, if Roche terminates the R&D Collaboration in its entirety on or before Initiation of the first Phase II Study for the Lead Product, the financial compensation owed to Dicerna for Roche Compounds shall be eliminated in its entirety.

(collectively, the “Non-Exclusive Conditions”).

20.3.2 Termination by Dicerna pursuant to Section 20.2.1 (Material Breach by Roche) or Section 20.2.2 (Insolvency)

Upon any termination by Dicerna pursuant to Section 20.2.1 (Material Breach by Roche) or Section 20.2.2 (Insolvency) all rights and licenses granted by Dicerna to Roche under this Agreement shall terminate in their entirety or on a Product-by-Product basis, as applicable, on the effective date of termination. If the alleged material breach by Roche is of its obligations under Article 4, then termination shall only be on a Product-by-Product basis.

If Dicerna desires to continue Development and/or Commercialization of Licensed Product(s), Dicerna shall give a Continuation Election Notice to Roche within [* * *] of Dicerna’s notice of such termination. If Roche receives such a timely Continuation Election Notice, then with respect to applicable Licensed Product(s) and to the extent reasonably requested by Dicerna:

(a) Roche hereby grants to Dicerna [* * *] license to Xxxxx Xxxxx-Back Patent Rights and (if such Licensed Product has achieved First Commercial Sale) the applicable Product Trademarks (in each case with the right to sublicense through multiple tiers), and a [* * *] license to Roche Know-How, solely to the extent necessary [* * *].

(b) After the effective date of termination Roche shall (or shall cause such other Roche Group member to), to the extent Roche has the right to do so, assign and transfer to Dicerna all regulatory filings and approvals, all final pre-clinical and clinical study reports and clinical study protocols, and all data, including clinical data, in Roche’s possession and control related to applicable Licensed Product(s) in the country reasonably necessary for Dicerna to continue to Develop and Commercialize the Licensed Product(s). To the extent Roche does not have the right to make such assignment and/or transfer, Roche shall, to the extent possible, provide a license, right of reference, or other right or access to such regulatory filings and approvals, pre-clinical and clinical study reports and protocols, and data. All data shall be transferred in the form and format in which it is maintained by Roche. Original paper copies shall only be transferred, if legally required. Roche shall not be required to prepare or finalize any new data, reports or information solely for purposes of transfer to Dicerna.

(c) Roche shall assign all clinical trial agreements for applicable Licensed Product(s), to the extent such agreements have not been cancelled in good faith and are assignable without Roche breaching such agreement (any required consideration to be paid by Roche). In any event, Roche shall cooperate and make all reasonable efforts to provide an orderly transition of clinical activities and continue such agreements to support such transition.

(d) Dicerna shall, upon transfer, have the right to disclose such filings, approvals and data to (i) governmental agencies of the country to the extent required or desirable to secure government approval for the development, manufacture or sale of Licensed Product(s) in the country, (ii) Third Parties acting on behalf of Dicerna, its Affiliates or licensees, to the extent reasonably necessary for the development, manufacture, or sale of Licensed Product(s) in the country, and (iii) Third Parties to the extent reasonably necessary to market Licensed Product(s) in the country.

(e) In consideration for the above license and transfers, and Roche’s work on applicable Licensed Product(s), Dicerna shall pay Roche a royalty on all net sales (as determined by reasonable accounting methods) of Licensed Product(s) by Dicerna, its Affiliates or licensees, mutatis mutandis, with the royalty rate as follows:

Status of Product at termination effective date	Royalty rate for Lead Product	Royalty rate for other Licensed Products
[* * *]	[* * *]	[* * *]
[* * *]	[* * *]	[* * *]
[* * *]	[* * *]	[* * *]

Notwithstanding the foregoing, Dicerna shall pay a [* * *] royalty on net sales for Licensed Products (other than with the Lead Product) that are Combination Products and where Roche has at least Completed a Phase I Study if Roche elects to not provide transfer and license access to the other therapeutically active ingredients contained in such Combination Product.

20.3.3 Termination by Roche without Cause or for Material Breach by Dicerna or Dicerna’s Insolvency, or Termination for Patent Challenge

Subject to the Non-Exclusive Conditions, upon any termination by Roche without cause (under Section 20.2.4 or Section 20.2.5), for Dicerna’s Insolvency, for material breach by Dicerna or for Patent Challenge (under Section 20.2.6), the rights and licenses granted by Dicerna to Roche under this Agreement shall terminate in their entirety or with respect to the R&D Collaboration or all Dicerna Compounds, or on a Licensed Product-by-Licensed Product, Selected Target-by-Selected Target or Research Plan-by-Research Plan basis, as applicable, on the effective date of termination.

If Dicerna desires to continue Development and/or Commercialization of Licensed Product(s), Dicerna shall give a Continuation Election Notice to Roche within [* * *] of receipt of Roche’s notice of termination without cause. If Roche receives such a timely Continuation Election Notice, then with respect to applicable Licensed Product(s) and to the extent reasonably requested by Dicerna:

(a) Roche hereby grants to Dicerna an exclusive, royalty-bearing, worldwide license to Xxxxx Xxxxx-Back Patent Rights and (if such Licensed Product has achieved First Commercial Sale) the applicable Product Trademarks (in each case with the right to sublicense through multiple tiers), and a non-exclusive, royalty-free, worldwide license to Roche Know-How, solely to the extent reasonably necessary to allow Dicerna, its Affiliates or licensees to develop, have developed, manufacture, have manufactured, use, offer to sell, sell, promote, export and import the applicable Licensed Product(s) in the applicable country(ies). For clarity, the licenses under this Section 20.3.3(a) shall not include any licenses that Roche has with a Third Party for which such grant would be prohibited or under which a member of the Roche Group would incur financial obligations to such Third Party.

(b) After the effective date of termination Roche shall, to the extent Roche has the right to do so, assign and transfer to Dicerna all regulatory filings and approvals, all final pre-clinical and clinical study reports and clinical study protocols, and all data, including clinical data, in Roche’s possession and control related to applicable Licensed Product(s) in the country reasonably necessary for Dicerna to continue to Develop and Commercialize the Licensed Product(s). To the extent Roche does not have the right to make such assignment and/or transfer, Roche shall, to the extent possible, provide a license, right of reference, or other right or access to such regulatory filings and approvals, pre-clinical and clinical study reports and protocols, and data. All data shall be transferred in the form and format in which it is maintained by Roche. Original paper copies shall only be transferred, if legally required. Roche shall not be required to prepare or finalize any new data, reports or information solely for purposes of transfer to Dicerna.

(c) Roche shall assign all clinical trial agreements for the applicable Licensed Product(s), to the extent such agreements have not been cancelled in good faith and are assignable without Roche paying any consideration or commencing litigation in order to effect an assignment of any such agreement, provided that Roche has agreed to such consideration in good faith and has given Dicerna notice of the requisite amount of consideration and affording Dicerna the opportunity to provide such consideration. In any event, Roche shall cooperate and make all reasonable efforts to provide an orderly transition of clinical activities and continue such agreements to support such transition.

(d) Dicerna shall, upon transfer, have the right to disclose such filings, approvals and data to (i) governmental agencies of the country to the extent required or desirable to secure government approval for the development, manufacture or sale of Licensed Product(s) in the country; (ii) Third Parties acting on behalf of Dicerna, its Affiliates or licensees, to the extent reasonably necessary for the development, manufacture, or sale of Licensed Product(s) in the country, and (iii) Third Parties to the extent reasonably necessary to market Licensed Product(s) in the country.

(e) In consideration for the above license and transfers, and Roche’s work on applicable Licensed Product(s), Dicerna shall pay Roche a royalty on all net sales (as determined by reasonable accounting methods) of Licensed Product(s) by Dicerna, its Affiliates or licensees, mutatis mutandis, with the royalty rate as follows:

Status of Product at termination effective date	Royalty rate for Lead Product	Royalty rate for other Licensed Products
[* * *]	[* * *]	[* * *]
[* * *]	[* * *]	[* * *]
[* * *]	[* * *]	[* * *]

Notwithstanding anything to the contrary herein, if Roche terminates an individual Selected Target without replacing it with another under the procedures set forth in Section 3.6, then all Additional Dicerna Compounds related to such Selected Target shall revert to Dicerna free of charge.

20.3.4 Direct License

Irrespective of anything to the contrary in this Agreement,

(a) any Compulsory Sublicense shall remain in full force and effect as may be required by Applicable Law, and

(b) any existing sublicense granted by Roche (and any further sublicenses thereunder) in accordance with Section 2.4.2 shall, upon the written request of Roche, remain in full force and effect, provided that (i) such Sublicensee is not then in breach of its sublicense agreement (and, in the case of termination by Dicerna for breach by Roche, that such Sublicensee and any further sublicensees did not cause the breach that gave rise to the termination by Dicerna); (ii) Dicerna continues to receive the amounts for development and regulatory event payments and sales based events as set forth in Sections 11.2 and 11.3; (iii) the royalty rates in such sublicense agreement are equal to the royalty rates set forth in Section 11.4 and are received by Dicerna; and (iv) such Sublicensee agrees in writing to be bound to Dicerna under the terms and conditions of such sublicense agreement and the applicable terms of this Agreement.

20.3.5 Other Obligations

20.3.5.1 Obligations Related to Ongoing Activities

In the case of termination by Dicerna according to Section 20.2.1 or 20.2.2 or by Roche under Section 20.2.4, if Dicerna elects to Develop the applicable Licensed Product(s), Roche shall transfer all existing and available clinical material to Dicerna at Roche’s fully burdened manufacturing cost. Dicerna shall assume all liability for the use of such material.

(b) Commercial Supplies

In the case of termination by Dicerna according to Section 20.2.1 or 20.2.2 or by Roche under Section 20.2.4, if a Licensed Product is marketed in any country of Territory on the date of the notice of termination of this Agreement, upon the request of Dicerna, Roche shall manufacture and supply reasonable amounts of such Licensed Product to Dicerna under a manufacturing transfer and transition plan for a period that shall not exceed [* * *] from the effective date of the termination of this Agreement at a price to be agreed by the Parties in good faith, but in no event

For purposes of clarity, irrespective of anything to the contrary in this Agreement:

(a) Dicerna may not give a Continuation Election Notice to Roche for Licensed Products (other than the Lead Product) that have not advanced into Development by or on behalf of Roche as of the effective date of termination.

(b) All transfers and licenses from Roche to Dicerna (or other obligations of Roche) under Section 20.3 are solely (i) where the Licensed Product contains both the Lead Compound and a Selected Target Compound, only with respect to the applicable Dicerna Compound(s) that have been previously terminated or are subject to the termination, (ii) with respect to Licensed Product(s) that are not (A) Combination Product(s) containing a compound that is proprietary to Roche or subject to Third Party rights or (B) Companion Diagnostics, and (iii) for the applicable Licensed Product that is being Developed or Commercialized by or on behalf of Roche as it exists on the effective date of termination. Such transfers, licenses and obligations do not extend to other therapeutically active ingredients or products, even if physically mixed, combined or packaged together with a Licensed Product, and even if a Licensed Product is intended (according to the investigation plan, proposed labeling or actual labeling, as applicable) for use with such other therapeutically active ingredients or products.

(c) In connection with research studies, clinical trials or other activities associated with the Development and Commercialization of Licensed Products, Roche may have collected (i) personally identifiable information about individual human subjects and/or (ii) human biological samples (collectively, “PII/Samples”). Legal and contractual restrictions may apply to such PII/Samples. Roche shall have no obligation to transfer such PII/Samples unless reasonably necessary or useful for the continued Development of the Licensed Product, in which case Roche shall not be obliged to transfer any PII/Samples that Roche in good faith believes would be prohibited or would subject Roche to potential liability by reason of Applicable Law, insufficient patient consent or contractual restrictions (however for contractual restrictions, upon request of Dicerna Roche

will facilitate an introduction to the applicable contractual party and allow Dicerna to contract directly with such contractual party, if possible). If Roche transfers any such PII/Samples, Dicerna shall use for the sole purpose of Developing and Commercializing the Licensed Product, and Dicerna shall be responsible for the correct use of the PII/Samples in line with Applicable Law and the informed consent forms (including but not limited to potential re-consenting of the patients at Dicerna’s costs).

If Dicerna desires Roche Transfer Activities other than Dicerna-Originated Transfer Activities, Dicerna shall make a payment to Roche of [* * *] (“Minimum Transfer Payment”). The Minimum Transfer Payment shall be non-refundable, but shall be fully creditable against Dicerna’s reimbursement for the Roche Transfer Activities. Roche shall be under no obligation to provide Roche Transfer Activities (beyond than Dicerna-Originated Transfer Activities) prior to receipt of the Minimum Transfer Payment or if the Minimum Transfer Payment is received after the effective date of the termination.

(e) Unless otherwise agreed to by the Parties, transfer of physical materials that are required under Roche Transfer Activities (except in conjunction with such future toll manufacturing obligations as may apply under Section (b), if applicable) shall be delivered CPT Dicerna or Dicerna’s designee to the location designated by Dicerna (Incoterms 2010).

(f) Neither Party may use any documents or materials provided by the other Party as part of any license or transfer under this Section 20.3 as evidence in any legal proceedings against the providing Party, however this exception will not apply to documents or materials exchanged pursuant to discovery requests or other litigation processes.

20.3.5.5 Royalty and Payment Obligations; Return of Information and Technology

Termination of this Agreement by a Party, for any reason, shall not release Roche from any obligation to pay royalties or make any payments to Dicerna that accrued prior to the effective date of termination. Termination of this Agreement by a Party, for any reason, will release Roche from any obligation to pay royalties or make any payments to Dicerna that would otherwise accrue on or after the effective date of termination.

22.2 Disputes

Unless otherwise set forth in this Agreement, in the event of any dispute between the Parties arising out of or relating to this Agreement (each, a “Dispute”) and the Parties cannot resolve such Dispute (through their respective Alliance Directors or the JRC or JSC, if and as applicable) within [* * *] of a written request by either Party to the other Party (“Notice of Dispute”), and such Dispute is not one for which a Party has final decision-making as expressly set forth in this Agreement, such Dispute shall be referred to the respective executive officers of the Parties designated below or their designees, for good faith negotiations attempting to resolve the Dispute. The designated executive officers are as follows:

For Dicerna:    CEO

For Roche:    Head of Pharma Partnering

22.3 Arbitration

Except for an Excluded Claim, should the Parties fail to resolve a Dispute within [* * *] after delivery of a Notice of Dispute, then such Dispute shall be finally resolved by binding arbitration by [* * *] arbitrators experienced in the business of pharmaceuticals in accordance with the commercial arbitration rules of the International Chamber of Commerce (ICC) as in force at the time when initiating the arbitration applying the substantive law specified in Section 22.1. The right and obligation to arbitrate under this Section 22.3 shall extend to any claims by or against the Parties and their respective Affiliates and any agents, principals, officers, directors or employees of either of the Parties or their respective Affiliates.

Each Party shall nominate one arbitrator. Should the claimant fail to appoint an arbitrator in the request for arbitration within [* * *] of being requested to do so, or if the respondent should fail to appoint an arbitrator in its answer to the request for arbitration within [* * *] of being requested to do so, the other Party shall request the ICC Court to make such appointment.

The arbitrators nominated by the Parties shall, within [* * *] from the appointment of the arbitrator nominated in the answer to the request for arbitration, and after consultation with the Parties, agree and appoint a third arbitrator, who will act as a chairman of the Arbitral Tribunal. Should such procedure not result in an appointment within the [* * *] time limit, either Party shall be free to request the ICC Court to appoint the third arbitrator.

Where there is more than one claimant and/or more than one respondent, the multiple claimants or respondents shall jointly appoint one arbitrator.

If any Party-appointed arbitrator or the third arbitrator resigns or ceases to be able to act, a replacement shall be appointed in accordance with the arrangements provided for in this Section.

The place of arbitration shall be [* * *]. The language to be used shall be English.

Either Party, without waiving any remedy under this Agreement, may seek from any court having jurisdiction any temporary injunctive or provisional relief necessary to protect the rights or property of that Party. Once the arbitrators are in place, either Party may also apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved, and either Party may apply to a court of competent jurisdiction to enforce interim injunctive relief granted by the arbitrators. Any final award by the arbitrators may be entered by either Party in any court having appropriate jurisdiction for a judicial recognition of the decision and applicable orders of enforcement. The arbitrators may render early or summary disposition of any or some issues after the Parties have had a reasonable opportunity to make submissions on such issues. The arbitrators shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damages. Each Party shall bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrators’ fees and any administrative fees of arbitration, unless the arbitrators determine otherwise.

Except to the extent necessary to confirm an award or as may be required by law, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties.

Roche and Dicerna shall cooperate fully with each other in connection with the making of all such filings or responses. Each Party shall bear its own fees in connection with its respective filing under this Section 22.4 and each Party shall bear their respective attorneys’ fees in connection therewith. This Agreement shall bind the Parties upon execution and continue in full force and effect unless and until the termination or expiration of the Agreement by its terms; provided, however, that this Agreement (including Dicerna’s grant of license rights hereunder, Roche’s obligation to make the payments hereunder, and each Party’s performance of discovery, research, transfer development, communications with regulatory authorities and other activities, and other rights and obligations hereunder in connection with the Compounds and Products), other than this Section 22.4, shall not become effective or binding unless and until each of the following conditions are met: (i) the waiting period provided by the HSR Act shall have expired or been terminated, (ii) no court or administrative challenges to the transactions commenced by the FTC or DOJ are pending, and (iii) no court or administrative orders commenced by the FTC or DOJ are outstanding blocking the completion of the transactions, (the date of such, the “Effective Date”).

Dicerna Enters Agreement with Roche to Develop and Commercialize
DCR-HBVS for the Treatment of Chronic Hepatitis B Virus (HBV) Infection

– Roche to gain worldwide license to Dicerna’s novel RNAi therapy currently in Phase 1 –

– Dicerna to receive $200 million upfront plus up to $1.47 billion in potential milestone payments related to DCR-HBVS –

– Dicerna to retain option to co-fund pivotal development of DCR-HBVS worldwide and
co-promote in U.S. with enhanced royalties –

– Collaboration includes discovery and development of additional therapies targeting multiple additional gene targets implicated in chronic HBV infection –

CAMBRIDGE, Mass., November 1, 2019 – Dicerna™ Pharmaceuticals, Inc. (Nasdaq: DRNA) today announced a research collaboration and licensing agreement with Roche (SIX: RO, ROG; OTCQX: RHHBY) to develop novel therapies for the treatment of chronic hepatitis B virus (HBV) infection using Dicerna’s proprietary GalXC™ RNAi platform technology. The collaboration will focus on worldwide development and commercialization of DCR-HBVS, Dicerna’s investigational therapy in Phase 1 clinical development. The collaboration also includes the discovery and development of therapies targeting multiple additional human and viral genes associated with HBV infection using the technology platforms of both companies.

“Dicerna is excited to collaborate with Roche to realize the full potential of DCR-HBVS and leverage our GalXC platform to target and silence specific genes that contribute to chronic hepatitis B virus infection,” said Xxxxxxx X. Xxxxxxxxx, Ph.D., president and chief executive officer of Dicerna. “With its deep expertise in HBV and established global infrastructure, Roche is ideally suited to help us accelerate the development and commercialization of DCR-HBVS, pursue a cure for chronic HBV infection, and address this serious global threat to public health.”

"We are excited to engage in a clinical partnership and research collaboration with Dicerna,” said Xxxx Xxxxx, global head of Infectious Diseases at Roche Pharma Early Research & Development. “This partnership builds upon our existing portfolio and internal expertise and positions us well to develop a best-in-disease therapy to cure chronic HBV infection."

89

Under the terms of the agreement, Dicerna will receive $200 million in an initial upfront payment and may be eligible to receive up to an additional $1.47 billion over time for the achievement of specified development, regulatory and commercial milestones. In addition, Dicerna may be eligible to receive royalties based on potential product sales of DCR-HBVS. Dicerna retains an option to co-fund pivotal development of DCR-HBVS worldwide, which if exercised, entitles Dicerna to receive enhanced royalties and co-promote products including DCR-HBVS in the U.S.

Dicerna and Roche also agreed to collaborate on the research and development of additional therapies targeting multiple human and viral genes implicated in chronic HBV infection, using technology from both companies, for which Dicerna is eligible to receive additional milestones and royalties on any potential products.

The transaction is subject to the expiration or termination of the waiting period under the Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976 and other customary conditions.

About Chronic Hepatitis B Virus (HBV) Infection

Hepatitis B virus (HBV) is the world’s most common serious liver infection, with more than 292 million patients chronically infected, according to the World Health Organization. Chronic HBV infection, a condition characterized by the presence of the HBV surface antigen (HBsAg) for six months or more, claims more than 800,000 lives annually. HBV is also the primary cause of liver cancer (also known as hepatocellular carcinoma or HCC), which is the second-leading cause of cancer deaths in the world.¹ 

About DCR-HBVS and the DCR-HBVS-101 Clinical Trial

DCR-HBVS is an investigational drug in development for the treatment of chronic hepatitis B virus (HBV) infection. Current therapies for HBV, such as nucleoside analogs, can provide long-term viral suppression if taken continuously, but they rarely lead to long-term functional cures, as measured by the clearance of HBV surface antigen (HBsAg) and sustained HBV deoxyribonucleic acid (DNA) suppression in patient plasma or blood. By contrast, DCR-HBVS employs RNA interference to selectively knock down specific genes involved in the creation of HBV messenger RNA (mRNA) and the entry of the virus into liver cells. This approach leads to greater than 99.9% reduction in circulating HBsAg, as observed in mouse models of HBV infection. These data suggest that DCR-HBVS may induce clearance of HBsAg and contribute meaningfully to a functional cure for HBV.

Dicerna is conducting a Phase 1, randomized, placebo-controlled study designed to evaluate the safety and tolerability of DCR-HBVS in healthy volunteers (HVs) and in patients with non-cirrhotic chronic HBV infection.

About Dicerna's GalXC™ RNAi Technology Platform

Dicerna’s proprietary RNA interference (RNAi) technology platform, called GalXC™, aims to advance the development of next-generation RNAi-based therapies designed to silence disease-driving genes in the liver and other body systems. Liver-targeted GalXC-based compounds enable subcutaneous delivery of RNAi therapies that are designed to specifically bind to receptors on liver cells, leading to internalization and access to the RNAi machinery within the cells. The GalXC approach seeks to optimize the activity of the RNAi pathway so that it operates in the most specific and potent fashion. Compounds produced via GalXC are intended to be broadly applicable across multiple therapeutic areas, including both liver and non-liver indications.

About Dicerna^TM Pharmaceuticals, Inc.

Dicerna™ Pharmaceuticals, Inc., is a biopharmaceutical company using ribonucleic acid (RNA) interference (RNAi) to develop medicines that silence genes that cause disease. The Company’s proprietary GalXC™ technology is being applied to develop potent, selective, and safe RNAi therapies for treatment of rare diseases, chronic liver diseases, cardiovascular diseases, neurodegenerative diseases, pain, and viral infectious disease. Dicerna aims to treat disease by addressing the underlying causes of illness with capabilities that extend beyond the liver to address a broad range of diseases, focusing on target genes where connections between gene and disease are well understood and documented. Dicerna intends to discover, develop, and commercialize novel therapies either on its own or in collaboration with pharmaceutical partners. Dicerna has strategic collaborations with Xxxxx, Xxx Xxxxx and Company (Lilly), Alexion Pharmaceuticals, Inc. (Alexion), and Boehringer Ingelheim International GmbH (BI).
