ARTICLE 1.
RESEARCH AND DEVELOPMENT

1.1. Overview. The intent of the Collaboration is for the Parties to conduct two research programs in parallel focused on (i) an Isis HTT program initially centered around the research of Allele Selective Compounds and Non-Allele Selective Compounds to designate an Isis Development Candidate, and (ii) a collaborative HTT program between Isis and Roche, funded by Roche, involving Roche’s proprietary technology designed to enhance delivery of molecules through the blood-brain barrier (“Brain Shuttle”), where the Parties will combine an Isis Compound with such Brain Shuttle technology to develop a Brain Shuttle Development Candidate. From the Effective Date until the date the Option is exercised, expires or is terminated (the “Option Period”), Isis will Develop and fund the initial Isis Development Candidate through the first Phase 1 Trial, and Roche will have an Option to obtain an exclusive license to further Develop and Commercialize the Development Candidates. Drugs from either or both program(s) may move forward in development based on data and the commercial market of the individual drugs. If Roche exercises its Option, Roche will be responsible for all further pre-clinical, clinical, regulatory, manufacturing and commercial activities related to Products. The purpose of this Section 1.1 is to provide a high-level overview of the roles, responsibilities, rights and obligations of each Party under this Agreement with regard to the R&D Plans and Products, and therefore this Section 1.1 is qualified in its entirety by the more detailed provisions of this Agreement set forth below.

1.2. Isis Development Candidate-R&D Plan.

1.2.1. Isis Development Candidate-R&D Plan Activities. The Isis Development Candidate-R&D Plan is attached hereto as APPENDIX 2, and sets forth the research and development activities the Parties will conduct during the Option Period with the first Compound designated an Isis Development Candidate, and through completion of the Registration-Directed Trials. As of the Effective Date, the Isis Development Candidate-R&D Plan focuses primarily on the research and Development of Non-Allele Selective Compounds, and is intended to achieve designation of one Isis Development Candidate and one Back-Up Compound. If the Parties subsequently decide to expand the efforts under such plan on the research and Development of Allele Selective Compounds, the Parties will mutually agree on any appropriate changes to the Isis Development Candidate-R&D Plan, with Roche being responsible for the incremental cost of any such changes.

1.2.2. Conducting the Isis Development Candidate-R&D Plan. During the Option Period, Roche and Isis will each use Commercially Reasonable Efforts to conduct the research and Development activities designated for each of them, respectively under the Isis Development Candidate-R&D Plan in accordance with the timelines specified therein, giving due consideration to the recommendations and advice of the JSC; provided, neither Roche nor Isis will have any obligation to perform any activity that, after having consulted the JSC, it in good faith believes

that continuing such activity would violate any Applicable Law, ethical principles, or principles of scientific integrity.

1.2.3. Isis’ Performance Milestones. During the Option Period, Isis will use Commercially Reasonable Efforts to:

(a) Designate at least one Isis Development Candidate by [***]; provided, however, that if research or Development issues arise that are outside of Isis’ reasonable control and make such designation by such date impossible, the Parties will negotiate in good faith to revise the date by which Isis may designate an Isis Development Candidate;

(b) Within [***] designating an Isis Development Candidate, complete the [***] for such Isis Development Candidate; and

(c) Within [***] are completed for an Isis Development Candidate and Isis has obtained the [***], [***], [***] and [***] data generated from such [***] sufficient to support the [***], [***] for such Isis Development Candidate.

1.2.4. Notice of Isis Development Candidate Designation. When Isis first designates an Isis Development Candidate, Isis will notify Roche in writing promptly after such designation and, together with such notice, will provide Roche the applicable Development Candidate Data Package.

1.2.5. Isis Development Candidate IND-Enabling Toxicology Studies. Once available to Isis, Isis will promptly deliver to Roche the pharmacology, toxicology, histology and pharmacokinetic data generated from the IND-Enabling Toxicology Studies under the Isis Development Candidate-R&D Plan.

1.2.6. Phase 1 Trial. Isis will keep the JSC informed of the progress of the Phase 1 Trial. Once available to Isis, Isis will promptly deliver to Roche the applicable Phase 1 Trial Data Package.

1.2.7. [***]. Prior to the Initiation of the [***] for the Isis Development Candidate, the Parties will discuss and mutually agree on whether to conduct an [***] for such Isis Development Candidate. If the Parties mutually agree to conduct such an [***], then the [***] will be considered an Approved Change to the Isis Development Candidate-R&D Plan and the costs to conduct such [***] will be treated as Additional Costs in accordance with Section 1.6.1(b).

1.3. Conducting the Brain Shuttle Development Candidate-R&D Plan. In addition to the Isis Development Candidate-R&D Plan performed under Section 1.2 above, Roche and Isis will conduct a research collaboration under the Brain Shuttle Development Candidate-R&D Plan to identify a Brain Shuttle Development Candidate. The Brain Shuttle Development Candidate-R&D Plan is attached hereto as APPENDIX 3 and sets forth the research activities the Parties will conduct through designation of the Brain

Shuttle Development Candidate. Once the first Brain Shuttle Development Candidate is designated, Roche will update the Brain Shuttle Development Candidate-R&D Plan to cover Development activities for the first Brain Shuttle Development Candidate through the completion of Registration-Directed Trials, which plan will be consistent with the level of effort and diligence set forth in the Isis Development Candidate-R&D Plan. Changes to the Brain Shuttle Development Candidate-R&D Plan that affect the Isis R&D Activities thereunder must be unanimously agreed to by the JSC or, if the JSC no longer exists, by the Parties. Roche and Isis will each use Commercially Reasonable Efforts to conduct the research and Development activities designated for each of them, respectively under the Brain Shuttle Development Candidate-R&D Plan in accordance with the timelines specified therein, giving due consideration to the recommendations and advice of the JSC; provided, neither Roche nor Isis will have any obligation to perform any activity that, after having consulted the JSC, it in good faith believes that continuing such activity would violate any Applicable Law, ethical principles, or principles of scientific integrity.

1.3.1. Brain Shuttle Development Candidate Designation. If Roche, after consultation with the JSC, determines a Compound under the Brain Shuttle Development Candidate-R&D Plan is ready to start IND-Enabling Toxicology Studies, such Compound will be a “Brain Shuttle Development Candidate.”

1.3.2. Brain Shuttle Development Candidate IND-Enabling Toxicology Studies. Once available to Roche, Roche will promptly deliver to Isis the pharmacology, toxicology, histology and pharmacokinetic data generated from the IND-Enabling Toxicology Studies under the Brain Shuttle Development Candidate-R&D Plan.

1.3.3. Phase 1 Trial. Roche will use Commercially Reasonable Efforts to conduct the Phase 1 Trial for the Brain Shuttle Development Candidate under the Brain Shuttle Development Candidate-R&D Plan. Roche will keep Isis informed of the progress of each Phase 1 Trial through the JSC.

1.4. Disclosure of Results. Each Party will promptly disclose to the other Party via disclosure at JSC meetings the results of work performed by such Party under each R&D Plan. Isis and Roche will provide reports and analyses at each JSC meeting, and more frequently on reasonable request by the JSC, detailing the current status of each R&D Plan. If the JSC has dissolved, then each Party will promptly disclose such data and results directly to the other Party.

1.5. Development Management.

1.5.1. JSC. The Parties will establish a joint steering committee (the “JSC”) to provide advice and make recommendations on the conduct of the Collaboration consistent with the R&D Plans. The JSC will act as a forum for sharing information about the activities conducted by the Parties hereunder, as an advisory body, and will have decision-making authority to the extent set forth on SCHEDULE 1.5.1. The JSC will consist of two (2) qualified representatives appointed by Isis, and two (2) qualified representatives appointed by Roche. Prior to Option exercise, Isis will

designate one of its representatives to act as the chairperson of the JSC. After Option exercise, Roche will designate one of its representatives to act as the chairperson of the JSC. The chairperson will be responsible for overseeing the activities of the JSC. SCHEDULE 1.5.1 sets forth certain JSC governance matters. The JSC will determine the JSC operating procedures at its first meeting, which will be codified in the written minutes of the first JSC meeting. In addition, during the term of the JSC, CHDI will have the right to participate in JSC meetings as a non-voting observer; provided, however, if Isis and Roche reasonably determine in good faith after discussion with CHDI that, due to participation in programs with a potentially competitive drug, CHDI should no longer participate in JSC meetings and be exposed to program data, then Isis will provide CHDI with written notice of such determination and thereafter CHDI will no longer participate in meetings of the JSC. The CHDI observer shall be a person reasonably acceptable to both Roche and Isis.

1.5.2. Decision Making.

(a) Under the Isis Development Candidate-R&D Plan. Prior to Option exercise, except as provided below in Section 1.5.2(b), Isis will have the final decision-making authority regarding the conduct of the Isis Development Candidate-R&D Plan, and whether to accept and how to implement the JSC’s recommendations.

(b) With Respect to All Subsequent Isis Development Candidates. For the second and any subsequent Isis Development Candidates, subject to Section 1.5.2(e), Roche will have the final decision-making authority regarding whether to Initiate the IND-Enabling Toxicology Studies and all subsequent Development activities thereafter. If the first Compound designated an Isis Development Candidate is no longer being Developed, then the next Compound designated an Isis Development Candidate that takes its place will still be considered the “first” Isis Development Candidate for purposes of this Section 1.5.2(b), and the Isis Development Candidate-R&D Plan will be amended accordingly as mutually agreed by the Parties to cover any research and Development activities and related costs for such replacement Isis Development Candidate in accordance with Section 1.8 below.

(c) Under the Brain Shuttle Development Candidate-R&D Plan. Subject to Section 5.1 and Section 1.5.2(e), Roche will have the final decision-making authority regarding selection of Brain Shuttle Development Candidates, the conduct of the Brain Shuttle Development Candidate-R&D Plan, and whether to accept and how to implement the JSC’s recommendations.

(d) Development Decision Making After Option Exercise. After Option exercise and without limiting Roche’s obligations under this Agreement to use Commercially Reasonable Efforts, Roche will have the final

decision making authority for which Products to Initiate Phase 2 and all subsequent Clinical Trials. In addition, Roche will have full responsibility for designing, conducting, funding and implementing the further Development of Products, including clinical trials and regulatory submissions.

(e) Exceptions. If Roche’s exercise of its decision-making authority pursuant to Section 1.5.2(b), Section 1.5.2(c) or Section 1.5.2(d) would increase costs for any Isis R&D Activities, then such decision must be unanimously agreed to by the JSC or, if the JSC no longer exists, by the Parties.

1.5.3. Alliance Managers. Each Party will appoint a representative to act as its alliance manager (each, an “Alliance Manager”). Each Alliance Manager will be responsible for supporting the JSC and performing the activities listed in SCHEDULE 1.5.3.

1.6. Collaboration Costs and Expenses.

1.6.1. Isis Development Candidate-R&D Plan.

(a) Isis Development Candidate-R&D Plan Costs — Generally. During the Option Period, except as otherwise provided under Section 1.6.1(b), Isis will be responsible for all costs and expenses associated with the Isis R&D Activities designated under the Isis Development Candidate-R&D Plan for the first Compound designated an Isis Development Candidate, and Roche will be responsible for all costs and expenses associated with any Roche R&D Activities designated under the Isis Development Candidate-R&D Plan. Isis cannot change any of the Roche R&D Activities without the unanimous agreement of the JSC or, if the JSC no longer exists, Roche. As provided in Section 1.8, Roche is responsible for the costs of any research and Development activities for an Additional Isis Development Candidate.

(b) Additional Costs Associated with Approved Changes to the Isis Development Candidate-R&D Plan. Roche will be responsible for paying Isis quarterly in advance for any Additional Costs resulting from Approved Changes. Roche will review and approve the Additional Costs before any Approved Changes are implemented by Isis. Isis and Roche will update the Isis Development Candidate-R&D Plan to reflect any such Approved Changes and Isis will invoice Roche for any such Additional Costs quarterly in advance after such Additional Costs are approved. Isis may reasonably estimate its FTE time required to perform the Approved Changes. Roche will pay the invoices submitted pursuant to this Section 1.6.1(b) for such approved Additional Costs within thirty (30) days after Roche’s receipt of the applicable invoice. Isis will use its Commercially Reasonable Efforts to complete Approved Changes

within the amount of the agreed Additional Costs. If at any time during the performance of the Approved Changes, Isis expects its actual Additional Costs to be greater than [***] of the previously agreed Additional Costs for a particular Approved Change(s) (the difference being “Change Overruns”), then Isis shall promptly notify the JSC which will then discuss and agree whether the Approved Changes should continue, and if so, how the Parties shall share the cost of any Change Overruns. Any Change Overruns Roche agrees to pay will be considered Additional Costs. Unless approved by Roche, Roche will not be responsible for Change Overruns that are greater than [***] of the previously agreed Additional Costs for a particular Approved Change(s).

(c) Reconciliation of Any Overpayment or Underpayment of Additional Costs. At the end of every second (2nd) and fourth (4th) Calendar Quarter during any period where Additional Costs are incurred (and again at the completion of all of the Approved Changes), Isis will provide Roche with an accounting of actual costs incurred by Isis (including Isis’ estimated FTE costs) compared to the Additional Costs paid in advance by Roche. After such accounting, if Isis’ actual costs incurred were greater than the Additional Costs paid in advance by Roche, then Roche will pay Isis the amount of such difference within thirty (30) days after Isis provides the accounting to Roche and Roche’s receipt of an invoice from Isis. If, however, after such accounting Isis’ actual costs incurred were less than the Additional Costs paid in advance by Roche, then Isis will provide Roche the amount of such difference in the form of a credit against the next payment (including any future payments for any then ongoing Approved Changes) to be paid by Roche to Isis under this Agreement.

1.6.2. Brain Shuttle Development Candidate-R&D Plan.

(a) Brain Shuttle Development Candidate-R&D Plan Costs. Roche will be responsible for all costs and expenses associated with the Brain Shuttle Development Candidate-R&D Plan, including pre-clinical in vitro or in vivo efficacy studies costs, manufacturing costs, IND-Enabling Toxicology Study costs, chronic toxicology study costs, clinical trial costs (including OLE Trial costs), and all costs and expenses associated with the Isis R&D Activities and the Roche R&D Activities designated under the Brain Shuttle Development Candidate-R&D Plan.

(b) Brain Shuttle Development Candidate-R&D Plan — Cost Estimates and Invoicing.

(i) Brain Shuttle Program Cost Estimate. Roche will pay Isis in advance on a quarterly basis for Isis’ performance of the Isis R&D Activities designated under the Brain Shuttle Development

Candidate-R&D Plan to progress to the next significant stage of research or development at the then-applicable Isis FTE Rate, plus any reasonable out-of-pocket expenses incurred by Isis in performing such work. The costs of ASOs to be supplied by Isis under the Brain Shuttle Development Candidate-R&D Plan will be calculated in accordance with SCHEDULE 1.6.2(b)(i). Isis may reasonably estimate its FTE time required to perform the Isis R&D Activities designated under the Brain Shuttle Development Candidate-R&D Plan. Each time the Parties agree to, or expand, the Isis R&D Activities under the Brain Shuttle Development Candidate-R&D Plan, Isis will provide Roche with a good faith estimate of the internal and external costs (each such estimate, a “Brain Shuttle Program Cost Estimate”) to conduct such Isis R&D Activities to the end of the next significant stage of research or development, and Isis and Roche will endeavor to mutually agree on a final Brain Shuttle Program Cost Estimate.

(ii) Payment Schedule and Invoicing; Reconciliation of Any Overpayment or Underpayment of Additional Costs. Once a given Brain Shuttle Program Cost Estimate is finalized under Section 1.6.2(b)(i) and Isis is ready to start such work, Isis will deliver to Roche each quarter in advance an invoice for Isis’ estimated costs for the coming Calendar Quarter. Roche will pay Isis within thirty (30) days after receiving such invoice. Isis will use its Commercially Reasonable Efforts to complete the Isis R&D Activities related to a given Brain Shuttle Program Cost Estimate within the amount of the agreed Brain Shuttle Program Cost Estimate. For each Brain Shuttle Program Cost Estimate, Isis and Roche will handle any cost overruns and reconciliations of any overpayment or underpayment of Additional Costs using the same process used under Section 1.6.1(b) and Section 1.6.1(c) above.

6.6. Limitations on Milestone Payments; Exceptions; Notice.

6.6.1. Each milestone payment set forth in TABLE 1, and in Column 1 of TABLE 2 above, will be paid only once upon the first achievement of the Milestone Event regardless of how many times such Milestone Event is achieved. On a Product-by-Product basis, each milestone payment set forth in Column 2 of TABLE 2 above will be paid only once upon the first achievement of the Milestone Event by the applicable Product. Each milestone payment set forth in TABLE 3 above will be paid only once upon the first achievement of the Milestone Event.

6.6.2. If a particular Milestone Event is not achieved because Development activities transpired such that achievement of such earlier Milestone Event was unnecessary or did not otherwise occur, then upon achievement of a later Milestone Event the Milestone Event payment applicable to such earlier Milestone Event will also be due. For example, if a Party proceeds directly to [***] without achieving the [***] then upon achieving the [***] Milestone Event, both the [***] and [***] Milestone Event payments are due.

6.6.3. Each time a Milestone Event is achieved under this ARTICLE 6, the Party that achieved such Milestone Event will send to the other Party a written notice thereof promptly (but no later than ten (10) Business Days) following the date of achievement of such Milestone Event and such payment will be due within thirty (30) days of the date such Milestone Event was achieved and receipt of an invoice by Roche from Isis.

6.7. Royalty Payments to Isis.

6.7.1. Roche Full Royalty. As partial consideration for the rights granted to Roche hereunder, subject to the provisions of this Section 6.7.1 and Section 6.7.2, Roche will pay to Isis royalties on Annual worldwide Net Sales of Products sold by Roche, its Affiliates or Sublicensees, on a country-by-country and Product-by-Product basis, in each case in the amounts as follows in TABLE 4 below (the “Roche Full Royalty”):

TABLE 4

		Royalty Rate for Products Comprising:
Royalty Tier	Annual Worldwide Net Sales	Isis Development Candidate	Brain Shuttle Development Candidate	Roche-Selected Brain Shuttle Development Candidate
1	For the portion of Annual Worldwide Net Sales < $[***]	[***]%	[***]%	[***]%
2	For the portion of Annual Worldwide Net Sales > $[*] but < $[*]	[***]%	[***]%	[***]%
3	For the portion of Annual Worldwide Net Sales > $[*] but < $[*]	[***]%	[***]%	[***]%
4	For the portion of Annual Worldwide Net Sales > $[***]	[***]%	[***]%	[***]%

(a) Annual worldwide Net Sales for a particular Product will be calculated by [***]. For clarity, notwithstanding any provision to the contrary in this Agreement, any consideration received by Roche or its Affiliates from a Compulsory Sublicensee solely for the sale of Products in a given Calendar Year will be added to Net Sales of Products for such year for purposes of determining which royalty tier (and therefore which royalty rate) applies to a particular Product in TABLE 4.

(b) Roche will pay Isis royalties on Net Sales of Products arising from named patient and other similar programs under Applicable Laws, and Roche will provide reports and payments to Isis consistent with Section 6.12. No royalties are due on Net Sales of Products arising from compassionate use and other programs providing for the delivery of Product at no cost. The sales of Products arising from named patient, compassionate use or other similar programs will not be considered a First Commercial Sale for purposes of determining the Full Royalty Period.

6.7.2. Application of Royalty Rates. All royalties set forth under Section 6.7.1 are subject to the provisions of this Section 6.7.2, and are payable as follows:

(a) Full Royalty Period. Roche’s obligation to pay Isis the Roche Full Royalty above with respect to a Product will continue on a country-by-country and Product-by-Product basis from the date of First Commercial Sale of such Product until the later of the date of expiration of (i) the last Valid Claim within the Licensed Patents or the Brain Shuttle Collaboration Patents Covering such Product in the country in which such

Product is used or sold, (ii) the data exclusivity period conferred by the applicable Regulatory Authority in such country with respect to such Product (e.g., such as in the case of an orphan drug), or (iii) the [***] anniversary of the First Commercial Sale of such Product in such country; provided, however, that, on a country-by-country and Product-by-Product basis, if neither of the periods set forth in clause (i) and clause (ii) of this Section 6.7.2(a) apply to a Product, then the Roche Full Royalty will continue to apply through the [***] anniversary of the First Commercial Sale of such Product in such country unless a [***] in such country, at which time in lieu of paying the Roche Full Royalty, Roche will pay Isis the Roche Reduced Royalty for such Product in such country in accordance with Section 6.7.2(b) (such royalty period, the “Full Royalty Period”). For clarity, (X) Licensed Patents that are jointly-owned by Roche, and (Y) Brain Shuttle Collaboration Patents that are jointly or solely-owned by Roche or its Affiliates, will count toward the calculation of the Full Royalty Period in a particular country if the use or sale of a Product by an unauthorized Third Party in such country would infringe a Valid Claim of such Licensed Patent or Brain Shuttle Collaboration Patent.

(b) Reduced Royalty Period. Subject to Section 6.7.2(c), on a country-by-country and Product-by-Product basis, after the expiration of the Full Royalty Period in a country and until the end of the Reduced Royalty Period, in lieu of the royalty rates set forth in TABLE 4 of Section 6.7.1, Roche will pay Isis royalty rates (the “Roche Reduced Royalty”) on Net Sales of Products in such country calculated on a Calendar Quarter-by-Calendar Quarter basis by [***]; provided, however, that the Roche Reduced Royalty rate in each country will in no event exceed the Reference Rate applicable under this Section 6.7. For example, if peak Calendar Year Net Sales of a Product comprising an Isis Development Candidate during the Full Royalty Period were [***] and royalties paid for that same Calendar Year were [***] resulting in a [***], and if [***] and the [***], the applicable [***] in such country would be [***]. Similarly, if the quarterly [***], then the applicable [***] in such country would be [***].

(c) Limitation on Aggregate Reduction for Roche Royalties.

(i) In no event will the aggregate royalty reductions under Section 6.7.2(b) and/or Section 6.8 reduce the royalties payable to Isis on Net Sales of a Product in any given period to an amount that is less than the [***].

(ii) In no event will the aggregate royalty offsets under Section 6.11.3(b) reduce the royalties payable to Isis on Net Sales of a Product in any given period to an amount that is less than the greater of (i) [***], and (ii) [***].

(d) End of Royalty Obligation. On a country-by-country basis, other than [***], Roche’s obligation to make royalty payments hereunder in such country will end on the expiration of the Reduced Royalty Period in such country. “Reduced Royalty Period” means, on a country by country basis, the period commencing upon the expiration of the [***] in such country and ending when the [***] (i) with respect to Net Sales of Products in Major Markets, [***], and (ii) [***].

(e) Royalty Examples. SCHEDULE 6.7.2(e) attached hereto contains examples of how royalties will be calculated under this Section 6.7.

(f) Allocation of Net Sales. If, by reason of one or more royalty rate adjustments under this Section 6.7.2, different royalty rates apply to Net Sales of Products from different countries, Roche will [***] such Net Sales [***]. SCHEDULE 6.7.2(f) attached hereto contains examples of how Net Sales of Products from different countries at different royalty rates will be [***].

6.8. Royalty Reduction Due to Decline In Product Sales Clearly Attributable to Sales of an [***]. If, after taking into account the then available data, including but not limited to epidemiology data, any Third Party product sales and diagnostics sales data and relevant market research information, Roche determines (and provides written notice to Isis of such determination and the basis therefor) that any decline in sales of the AS Development Candidate being Commercialized by Roche is clearly attributable to the sales of any [***], then, subject to Section 6.7.2(c)(i), the royalty rates under TABLE 4 applicable to such AS Development Candidate being Commercialized by Roche, its Affiliates or Sublicensees [***]. For example, if Roche determines such decline in sales to be [***], then Roche shall reduce royalties otherwise payable to Isis based on the actual Net Sales for that Calendar Quarter [***]. If Roche implements a royalty reduction under this Section 6.8, Roche will make such reductions with a one Calendar Quarter delay in order to generate the data and supporting calculations necessary to determine the amount of any such reduction, and Roche shall include its calculation of such reduction in the applicable royalty report under Section 6.12.2. If Isis believes that any decline in sales of the AS Development Candidate being Commercialized by Roche is not clearly attributable to the sales of any such [***], the Parties will discuss the matter in good faith and if the Parties cannot resolve such matter it will be resolved in accordance with the dispute resolution process set forth in Section 12.1. Roche is not entitled to any royalty reduction under this Section 6.8 as a result of sales of [***].

6.9. Apportionment of Compulsory Sublicensee Consideration. At such time as Roche or any of its Affiliates or Sublicensees enters into a sublicense with a Compulsory Sublicensee, the Parties will discuss and mutually agree upon an adjustment of the royalty due to Isis under Section 6.7 of this Agreement with respect to sales of Products by such Compulsory Sublicensee, with such adjustment calculated based on a [***].

6.10. Reverse Royalty Payments to Roche for Discontinued Products.

6.10.1. Reverse Royalty for a Discontinued Product Comprising an Isis Development Candidate. If Isis or any of its Affiliates or Sublicensees Commercializes a Discontinued Product for which Roche has paid Isis the license fee under Section 6.3 and such Discontinued Product (i) is comprised of an Isis Development Candidate, and (ii) was not commercialized by Roche, its Affiliates or its Sublicensees, then following the First Commercial Sale of such Discontinued Product by Isis or its Affiliates or Sublicensees, Isis will pay Roche a royalty of [***] of Annual worldwide net sales of such Discontinued Product (“Isis Development Candidate Reverse Royalties”). Isis will pay Roche such Isis Development Candidate Reverse Royalties in accordance with the provisions governing payment of royalties from Roche to Isis in Sections 6.7.2, 6.11, 6.12, 6.13, 6.14, and 6.15 (mutatis mutandis); provided, however, that Isis’ obligation to pay Roche Isis Development Candidate Reverse Royalties will expire once Isis has paid Roche an amount equal to [***] for such Discontinued Product under Section 6.2 and Section 6.4.

6.10.2. Reverse Royalty for a Discontinued Product Comprising a Brain Shuttle Development Candidate. If Roche has paid Isis the license fee under Section 6.3 and Isis or any of its Affiliates or Sublicensees Commercializes a Discontinued Product that is comprised of a Brain Shuttle Development Candidate, then following the First Commercial Sale of such Discontinued Product by Isis or its Affiliates or Sublicensees, Isis will pay Roche a royalty of [***] of Annual worldwide net sales of such Discontinued Product (“Brain Shuttle Development Candidate Reverse Royalties”). Isis will pay Roche Brain Shuttle Development Candidate Reverse Royalties in accordance with (and for the same duration as) the provisions governing payment of royalties from Roche to Isis in Sections 6.7.2, 6.11, 6.12, 6.13, 6.14, and 6.15, mutatis mutandis.

6.11. Third Party Payment Obligations.

6.11.1. Existing In-License Agreements.

(a) Isis’ Existing In-License Agreements. Certain of the Licensed Technology Controlled by Isis as of the Effective Date licensed to Roche under Section 4.1.1 are in-licensed or were acquired by Isis under the agreements with Third Party licensors or sellers listed on SCHEDULE 6.11.1 (such license or purchase agreements being the “Isis In-License Agreements”), and certain milestone or royalty payments and license maintenance fees may become payable by Isis to such Third Parties under the Isis In-License Agreements based on the Development or Commercialization of a Product by Roche under this Agreement. Any payment obligations arising under the Isis In-License Agreements as they apply to Products that:

(i) accrue prior to Option exercise, will be paid by [***] as [***]; and

(ii) accrue after Option exercise, will be paid by [***] as [***].

(b) Isis’ Agreements at the time of Option Exercise. Prior to Roche exercising the Option, Isis shall disclose to Roche all agreements (other than the In-License Agreements) entered into after the Effective Date by Isis with Third Party licensors or sellers under which Isis licensed or acquired any Licensed Technology to be licensed to Roche under Section 4.1.1 (“Additional Isis In-License Agreements”). Any payment obligations arising under any Additional Isis In-License Agreements as they apply to Products that:

(i) accrue prior to Option exercise, will be paid by [***] as [***]; and

(ii) accrue after Option exercise, will be paid by [***] as [***], in which case Section 6.11.3 will apply.

(c) Roche’s Existing In-License Agreements. Roche will be solely responsible for any Third Party Obligations that become payable by Roche to Third Parties under any agreements or arrangements Roche has with such Third Parties as of the Effective Date, based on the Development or Commercialization of a Product by Roche, its Affiliate or Sublicensee under this Agreement. Any such payment obligations will be paid by [***] as [***] under this Agreement.

6.11.2. New In-Licensed Product-Specific Patents.

(a) On a Product-by-Product basis, after Option exercise, Roche or Isis, as the case may be, will promptly provide the other Party written notice of any additional Third Party Patent Rights it has identified as necessary to Develop or Commercialize a Product where such Third Party Patent Rights would be considered a Product-Specific Patent if either Party Controlled such Patent Rights (“Additional Product-Specific Patents”), and Roche will have the first right, but not the obligation, to negotiate with, and obtain a license from the Third Party Controlling such Additional Product-Specific Patents. If Roche obtains any such Additional Product-Specific Patents then any financial obligations under such Third Party agreement will be paid solely by [***] as [***].

(b) If, however, Roche elects not to obtain such a license to such Additional Product-Specific Patents, Roche will so notify Isis, and Isis may obtain such a license to such Additional Product-Specific Patents and Isis will include such Additional Product-Specific Patents in the license granted to Roche under Section 4.1.1 provided that Roche agrees in writing to [***].

6.11.3. Additional Core IP In-License Agreements.

(a) Roche will promptly provide Isis written notice of any [***] (“Additional Core IP”) that Roche believes it has identified and Isis will have the first right, but not the obligation, to negotiate with, and obtain a license from the Third Party Controlling such Additional Core IP. For clarity, Additional Core IP does not include any Patent Rights claiming (or intellectual property related to) [***]. If Isis obtains such a Third Party license, Isis will include such Additional Core IP in the license granted to Roche under Section 4.1.1, and any financial obligations under such Third Party agreement will be paid solely by [***] as [***].

(b) If, however, Isis elects not to obtain such a license to such Third Party intellectual property, Isis will so notify Roche, and Roche may obtain such a Third Party license and, subject to Section 6.7.2(c)(ii), Roche may offset an amount equal to [***] of [***] paid by Roche under such Third Party license against any [***] of this Agreement in such country for [***].

(c) If Isis does not agree with Roche that a license to such Third Party Patent Rights is necessary to [***], then Isis will send written notice to such effect to Roche, and the Parties will engage a mutually agreed independent Third Party intellectual property lawyer with expertise in the patenting of ASOs, and appropriate professional credentials in the relevant jurisdiction, to determine the question of whether or not such Third Party intellectual property is Additional Core IP. The determination of the Third Party expert engaged under the preceding sentence will be binding on the Parties solely for purposes of determining whether Roche is permitted to [***]. The costs of any Third Party expert engaged under this Section 6.11.3(c) will be paid by the Party against whose position the Third Party lawyer’s determination is made.

6.12. Payments.

6.12.1. Commencement. Beginning with the Calendar Quarter in which the First Commercial Sale, named patient sale, compassionate use sale or other similar sales for a Product is made and for each Calendar Quarter thereafter, Roche will make royalty payments to Isis under this Agreement within [***] following the end of each such Calendar Quarter.

6.12.2. Royalty Reporting. Each royalty payment will be accompanied by a report, summarizing in writing for the relevant Calendar Quarter on a Product-by-Product basis the following information:

(a) Sales in Swiss Francs on a country-by-country basis;

(b) Net Sales in Swiss Francs on a country-by-country basis;

(c) Total worldwide Net Sales in Swiss Francs;

(d) Exchange rate used for the conversion of Net Sales from Swiss Francs to US Dollars pursuant to Section 6.12.4;

(e) Royalty Rate pursuant to Section 2.1.1(b)(ii) (if applicable), Section 6.7.1 and Section 6.7.2, as applicable; and

(f) Total Royalty payable in US Dollars.

In addition, Roche will include in each report under this Section 6.12.2 information regarding any Net Sales of Products sold for named patient, compassionate use or other similar sales and any consideration received from any Compulsory Sublicensees.

6.12.3. After first Approval, if no royalties or other payments from Product sales are payable in respect of a given Calendar Quarter, Roche will submit a written royalty report to Isis so indicating together with an explanation as to why no such royalties are payable. In addition, beginning with the Calendar Quarter in which the First Commercial Sale for a Product (or any named patient sale, compassionate use sale or other similar sales of a Product) is made and for each Calendar Quarter thereafter, within ten (10) Business Days following the end of each such Calendar Quarter, Roche will provide Isis a [***] report estimating the total (A) Sales and Net Sales for Products projected for such Calendar Quarter, and (B) if available, the amount of any consideration payable to Roche under sublicenses with Compulsory Sublicensees.

6.12.4. Mode of Payment. All payments under this Agreement will be (i) payable in full in U.S. Dollars, regardless of the country(ies) in which sales are made, (ii) made by wire transfer of immediately available funds to an account designated by Isis in writing, and (iii) irrevocable and non-refundable. Any corrections to calculations of royalty payments previously paid shall be adjusted to the next royalty payment due. When calculating the Sales of a Product that occur in currencies other than U.S. Dollars, Roche will convert the amount of such sales into Swiss Francs and then into U.S. Dollars using Roche’s then current internal foreign currency translation actually used on a consistent basis in preparing its audited financial statements (currently YTD average rate as reported by Reuters).

6.12.5. Records Retention. Commencing with the First Commercial Sale or named patient sale of a Product, Roche will keep complete and accurate records pertaining to the sale of Products for a period of [***] after the year in which such sales occurred, and in sufficient detail to permit Isis to confirm the accuracy of the Net Sales or royalties paid by Roche hereunder.

6.13. Audits. After the first Approval of a Product, during the remaining Agreement Term and for a period of thirty-six (36) calendar months thereafter, at the request and expense of Isis, Roche will permit an independent certified public accountant of internationally recognized standing appointed by Isis, at reasonable times and upon at least sixty (60)

Business Days written notice, but in no case more than once per Calendar Year, to examine such records as may be necessary for the purpose of verifying the calculation and reporting of Net Sales and the correctness of any royalty payment made under this Agreement for any period within the preceding thirty-six (36) calendar months. No Calendar Year can be audited more than once. Any and all records of Roche examined by such independent certified public accountant will be deemed Roche’s Confidential Information. The independent certified public accountant shall share all draft reports with Roche before the draft audit report is shared with Isis and before the final document is issued. Upon completion of the audit, the accounting firm will provide both Roche and Isis with a written report disclosing whether the royalty payments made by Roche are correct and the specific details concerning any discrepancies (“Audit Report”). If, as a result of any inspection of the books and records of Roche, it is shown that Roche’s payments under this Agreement were less than the royalty amount that should have been paid, then Roche will make all payments required to be made by paying Isis the difference between such amounts to eliminate any discrepancy revealed by said inspection with the next royalty payment due, with interest calculated in accordance with Section 6.15. If, as a result of any inspection of the books and records of Roche, it is shown that Roche’s payments under this Agreement were greater than the royalty amount that should have been paid, then [***]. Isis will pay all fees charged by such accountant pursuant to the audit, except that, if the audit determines that any additional amounts payable by Roche for an audited period exceed [***] of the amount actually paid for such audited period, then, in addition to paying Isis any unpaid amounts discovered in such audit, Roche will pay the fees and expenses charged by such accountant.

6.14. Taxes.

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

6.14.2. Withholding Tax. To the extent the paying Party is required to deduct and withhold taxes on any payment, the paying Party will pay the amounts of such taxes to the proper governmental authority for the account of the receiving Party and remit the net amount to the receiving Party in a timely manner. The paying Party will promptly furnish the receiving Party with proof of payment of such taxes. If documentation is necessary in order to secure an exemption from, or a reduction in, any withholding taxes, the Parties will provide such documentation to the extent they are able to do so. In accordance with the procedures set forth in Section 9.3, the receiving Party will also indemnify the paying Party for any tax, interest or penalties imposed on the paying Party if the paying Party improperly reduces or eliminates withholding tax based upon representations made by the receiving Party.

6.14.3. Tax Cooperation. At least fifteen (15) days prior to the date a given payment is due under this Agreement, the non-paying Party will provide the paying Party with any and all tax forms that may be reasonably necessary in order for the paying Party to lawfully not withhold tax or to withhold tax at a reduced rate with

respect to such payment under an applicable bilateral income tax treaty. Following the paying Party’s timely receipt of such tax forms from the non-paying Party, the paying Party will not withhold tax or will withhold tax at a reduced rate under an applicable bilateral income tax treaty, if appropriate under the Applicable Laws. The non-paying Party will provide any such tax forms to the paying Party upon request and in advance of the due date. Each Party will provide the other with reasonable assistance to enable the recovery, as permitted by Applicable Law, of withholding taxes resulting from payments made under this Agreement, such recovery to be for the benefit of the Party who would have been entitled to receive the money but for the application of withholding tax under this Section 6.14.

The provisions of this Section 6.14 are to be read in conjunction with the provisions of Section 12.4 below.

6.15. Interest. Any undisputed payments to be made hereunder that are not paid on or before the date such payments are due under this Agreement will bear interest at a rate per annum equal to the lesser of (i) one month LIBOR rate in effect on the date that such payment would have been first due plus two percentage points (2%) or (ii) the maximum rate permissible under applicable law.

ARTICLE 7.

INTELLECTUAL PROPERTY

7.1. Ownership.

7.1.1. Isis Technology and Roche Technology. As between the Parties, Isis will own and retain all of its rights, title and interest in and to the Licensed Know-How and Licensed Patents and Roche will own and retain all of its rights, title and interest in and to the Roche Know-How and Roche Patents, subject to any assignments, rights or licenses expressly granted by one Party to the other Party under this Agreement.

7.1.2. Agreement Technology. Each Party will promptly disclose to the other Party in writing, and will cause its Affiliates to so disclose, the discovery, development, or creation of any invention made solely or jointly by the Parties in connection with the performance of obligations under this Agreement. Except as expressly provided in this Agreement, neither Party will have any obligation to account to the other for profits with respect to, or to obtain any consent of the other Party to license or exploit, Jointly-Owned Collaboration Technology by reason of joint ownership thereof, and each Party hereby waives any right it may have under the laws of any jurisdiction to require any such consent or accounting.

7.1.3. Joint Patent Committee.

(a) The Parties will establish a “Joint Patent Committee” or “JPC.” The JPC will serve as the primary contact and forum for discussion between the Parties with respect to intellectual property matters arising under this Agreement, and will cooperate with respect to the activities set forth in this ARTICLE 7. Isis’ obligation to participate in the JPC will terminate upon the date Isis is no longer obligated to participate in the JSC. Thereafter, Isis will have the right, but not the obligation, to participate in JPC meetings. The JPC determines the invention classification for each invention arising under this Agreement. The classifications are (i) Brain Shuttle Collaboration Patents, (ii) Isis Product-Specific Patents, (iii) Jointly-Owned Collaboration Patents, (iv) Isis Core Technology Patents, and (v) Isis Manufacturing and Analytical Patents. In addition, with respect to the Brain Shuttle Collaboration Patents classification, the JPC will determine the following sub-categories of Brain Shuttle Collaboration Patents: (w) Patent Rights claiming inventions solely related to the Brain Shuttle Technology (“Brain Shuttle-Specific Collaboration Patents”); (x) Patent Rights claiming inventions solely related to ASOs that do not utilize the Brain Shuttle Technology (“ASO-Specific Collaboration Patents”); (y) Patent Rights claiming inventions solely related to the linking or conjugation of molecules (“Linker-Specific Collaboration Patents”); and (z) Patent Rights claiming more than one of the technologies described in items (w) through (y) above (“Omnibus Collaboration Patents”). The JPC will endeavor to separate the claims within such Patent Rights into separate and distinct patent applications corresponding with the categories and sub-categories described in this Section 7.1.3(a) to the extent possible without diminishing the patentability of the inventions.

(b) A strategy will be discussed with regard to (x) prosecution and maintenance, defense and enforcement of (A) Brain Shuttle Collaboration Patents, (B) Isis Product-Specific Patents, and (C) Jointly-Owned Collaboration Patents licensed to Roche under Section 4.1.1 in connection with a Product, (y) defense against allegations of infringement of Third Party Patent Rights, and (z) licenses to Third Party Patent Rights or Know-How (including whether to obtain any licenses under any such Third-Party Patent Rights or Know-How, and whether there are any known Third Party Obligations applicable to a particular Product), in each case to the extent such matter would be reasonably likely to have a material impact on the Agreement or the licenses granted hereunder, which strategy will be considered in good faith by the Party entitled to prosecute, enforce and defend such Patent Rights hereunder, but will not be binding on such Party. Notwithstanding the above, subject to the provisions of Section 6.11, Roche shall have final say as to whether to obtain any licenses under Third-Party Patent Rights or Know-How.

(c) In addition, the Joint Patent Committee will be responsible for the determination of inventorship. The determination of inventorship will be in accordance with United States patent laws and therefore will determine if the invention is solely or jointly owned by the relevant Party or Parties. In case of a dispute in the Joint Patent Committee (or otherwise between Isis and Roche) over inventorship or classification, if the Joint Patent Committee cannot resolve such dispute, even after seeking the JSC’s input, such dispute will be resolved by independent patent counsel not engaged or regularly employed in the past two years by either Party and reasonably acceptable to both Parties. The decision of such independent patent counsel will be binding on the Parties. Expenses of such patent counsel will be shared equally by the Parties.

(d) The JPC will comprise an equal number of members from each Party. The Joint Patent Committee will meet as often as agreed by them (and at least semi-Annually), to discuss matters arising out of the activities set forth in this ARTICLE 7. The JPC will determine by unanimous consent the JPC operating procedures at its first meeting. To the extent reasonably requested by either Party, the Joint Patent Committee will solicit the involvement of more senior members of their respective legal departments with respect to critical issues. Each Party’s representatives on the Joint Patent Committee will consider comments and suggestions made by the other in good faith. If either Party deems it reasonably advisable, the Parties will enter into a mutually agreeable common interest agreement covering the matters contemplated by this Agreement.

7.2. Prosecution and Maintenance of Patents.

7.2.1. Patent Filings. The Party responsible for Prosecution and Maintenance of any Patent Rights as set forth in Section 7.2.2 and Section 7.2.3 will endeavor to obtain patent protection for a Product as it Prosecutes and Maintains its other patents Covering products in development, using counsel of its own choice but reasonably acceptable to the other Party, in such countries as the responsible Party sees fit.

7.2.2. Licensed Patents and Roche Patents.

(a) Licensed Patents.

(i) Isis Core and Manufacturing Patents. Isis will at all times control and be responsible for all aspects of (i) any Brain Shuttle Collaboration Patents solely-owned by Isis that (A) include claims that are directed to subject matter applicable to ASOs in general, or (B) include an ASO, the sequence of which targets the RNA that encodes HTT and ASOs that do not target the RNA encoding HTT (each, an “Isis Core Brain Shuttle Collaboration Patent”), (ii) the Isis Core Technology Patents, and (iii) the Isis Manufacturing and Analytical Patents.

(ii) Isis Product-Specific Patents.

(1) Before Option Exercise. Before Option exercise, subject to Section 7.2.3 and Section 7.2.4, at Isis’ expense, Isis will control and be responsible for all aspects of the Prosecution and Maintenance of all (x) Brain Shuttle Collaboration Patents solely-owned by Isis that are necessary or useful to Develop or Commercialize a Product eligible to be licensed to Roche under Section 4.1.1 and are not necessary or useful to develop or commercialize products that are not Products (each, an “Isis Product-Specific Brain Shuttle Collaboration Patent”), and (y) Isis Product-Specific Patents, and will use commercially reasonably efforts to Prosecute and Maintain such Patent Rights.

(2) After Option Exercise. After Option exercise, subject to Section 7.2.3 and Section 7.2.4, at Roche’s expense, Roche will control and be responsible for all aspects of the Prosecution and Maintenance of all Isis Product-Specific Brain Shuttle Collaboration Patents and Isis Product-Specific Patents Covering Products licensed to Roche under Section 4.1.1 and will either (i) use commercially reasonably efforts to Prosecute and Maintain such Patent Rights or (ii) offer to assign Roche’s entire right, title and interest in such Patent Rights to Isis, in which case following any such assignment all licenses granted in this Agreement by Isis to Roche under such Patent Rights shall become non-exclusive and the exclusivity covenants under Section 2.1.1 will no longer apply to such Patent Rights.

(b) Roche Patents and Roche Brain Shuttle Collaboration Patents. Roche will control and be responsible for all aspects of the Prosecution and Maintenance of all (i) Brain Shuttle Collaboration Patents solely-owned by Roche, and (ii) Roche Patents, subject to Section 7.2.3 and Section 7.2.4.

7.2.3. Jointly-Owned Collaboration Patents.

(a) Before Option Exercise. Before Option exercise, (i) Isis will control and be responsible for all aspects of the Prosecution and Maintenance of Jointly-Owned Collaboration Patents Covering Isis Development Candidates, and (ii) Roche will control and be responsible for all aspects of the Prosecution and Maintenance of any Jointly-Owned Collaboration Patents Covering Brain Shuttle Development Candidates.

(b) After Option Exercise. After Option exercise, Roche will control and be responsible for all aspects of the Prosecution and Maintenance of (i) Jointly-Owned Collaboration Patents Covering Products, and (ii) jointly-owned Brain Shuttle Collaboration Patents, and will either (y) use commercially reasonably efforts to Prosecute and Maintain such Patent Rights or (z) offer to assign Roche’s entire right, title and interest in such Patent Rights to Isis, in which case following any such assignment all licenses granted in this Agreement by Isis to Roche under such Patent Rights shall become non-exclusive and the exclusivity covenants under Section 2.1.1 will no longer apply to such Patent Rights.

7.2.4. Other Matters Pertaining to Prosecution and Maintenance of Patents.

(a) Each Party will keep the other Party informed through the Joint Patent Committee as to material developments with respect to the Prosecution and Maintenance of the Product-Specific Patents or Jointly-Owned Collaboration Patents for which such Party has responsibility for Prosecution and Maintenance pursuant to Section 7.2.2, Section 7.2.3 or this Section 7.2.4, including by providing copies of material data as it arises, any office actions or office action responses or other correspondence that such Party provides to or receives from any patent office, including notice of all interferences, reissues, re-examinations, oppositions or requests for patent term extensions, and all patent-related filings, and by providing the other Party the timely opportunity to have reasonable input into the strategic aspects of such Prosecution and Maintenance.

(b) If Roche elects (a) not to file and prosecute patent applications for the Jointly-Owned Collaboration Patent or Isis Product-Specific Patents that have been licensed to Roche under this Agreement or the Brain Shuttle Collaboration Patents for which Roche has responsibility for Prosecution and Maintenance pursuant to Section 7.2.2 or Section 7.2.3 (“Roche-Prosecuted Patents”) in a particular country, (b) not to continue the prosecution (including any interferences, oppositions, reissue proceedings, re-examinations, and patent term extensions, adjustments, and restorations) or maintenance of any Roche-Prosecuted Patent in a particular country, or (c) not to file and prosecute patent applications for the Roche-Prosecuted Patent in a particular country following a written request from Isis to file and prosecute in such country, then Roche will so notify Isis promptly in writing of its intention in good time to enable Isis to meet any deadlines by which an action must be taken to establish or preserve any such Patent Right in such country; and Isis will have the right, but not the obligation, to file, prosecute, maintain, enforce, or otherwise pursue such Roche-Prosecuted Patent in the applicable country at its own expense with counsel of its own choice. In such case, Roche will cooperate with Isis to file for, or continue to Prosecute and

Maintain or enforce, or otherwise pursue such Roche-Prosecuted Patent in such country in Isis’ own name. Notwithstanding anything to the contrary in this Agreement, if Isis assumes responsibility for the Prosecution and Maintenance of any such Roche-Prosecuted Patent under this Section 7.2.4(b), Isis will have no obligation to notify Roche if Isis intends to abandon such Roche-Prosecuted Patent. The analogous situation shall apply mutatis mutandis with regard to Patent Rights (excluding Isis Core Technology Patents and Isis Manufacturing and Analytical Patents) for which Isis has responsibility for Prosecution and Maintenance pursuant to Section 7.2.2 or Section 7.2.3.

(c) The Parties, through the Joint Patent Committee, will cooperate in good faith to determine if and when any divisional or continuation applications will be filed with respect to any Jointly-Owned Collaboration Patents or Product-Specific Patents, and where a divisional or continuation patent application filing would be practical and reasonable, then such a divisional or continuation filing will be made.

(d) If the Party responsible for Prosecution and Maintenance pursuant to Section 7.2.3 intends to abandon such Jointly-Owned Collaboration Patent without first filing a continuation or substitution, then such Party will notify the other Party of such intention at least sixty (60) days before such Jointly-Owned Collaboration Patent will become abandoned, and such other Party will have the right, but not the obligation, to assume responsibility for the Prosecution and Maintenance thereof at its own expense (subject to Section 7.3.1) with counsel of its own choice, in which case the abandoning Party will, and will cause its Affiliates to, assign to the other Party (or, if such assignment is not possible, grant a fully-paid exclusive license in) all of their rights, title and interest in and to such Jointly-Owned Collaboration Patents. If a Party assumes responsibility for the Prosecution and Maintenance of any such Jointly-Owned Collaboration Patents under this Section 7.2.4(d), such Party will have no obligation to notify the other Party of any intention of such Party to abandon such Jointly-Owned Collaboration Patents.

(e) In addition, the Parties will consult, through the Joint Patent Committee, and take into consideration the comments of the other Party for all matters relating to interferences, reissues, re-examinations and oppositions with respect to those Patent Rights in which such other Party (i) has an ownership interest, (ii) has received a license thereunder in accordance with this Agreement, or (iii) may in the future, in accordance with this Agreement, obtain a license or sublicense thereunder.

7.3. Patent Costs.

7.3.1. Jointly-Owned Collaboration Patents. Unless the Parties agree otherwise, Isis and Roche will share equally the Patent Costs associated with the Prosecution and Maintenance of Jointly-Owned Collaboration Patents; provided that, either Party may decline to pay its share of costs for filing, prosecuting and maintaining any Jointly-Owned Collaboration Patents in a particular country or particular countries, in which case the declining Party will, and will cause its Affiliates to, assign to the other Party (or, if such assignment is not possible, grant a fully-paid exclusive license in) all of their rights, titles and interests in and to such Jointly-Owned Collaboration Patents.

7.3.2. Licensed Patents and Roche Patents. Except as set forth in Section 7.2.4 and Section 7.3.1, each Party will be responsible for all Patent Costs incurred by such Party prior to and after the Effective Date in all countries in the Prosecution and Maintenance of Patent Rights for which such Party is responsible under Section 7.2; provided, however, that after Option exercise, Roche will be solely responsible for Patent Costs arising from the Prosecution and Maintenance of the Isis Product-Specific Patents; provided that, Roche may decline to pay for filing, prosecuting and maintaining any Isis Product-Specific Patents in a particular country or particular countries, in which case all licenses granted in this Agreement by Isis to Roche under such Patent Rights shall become non-exclusive and the exclusivity covenants under Section 2.1.1 will no longer apply to such Patent Rights.

7.4. Defense of Claims Brought by Third Parties.

7.4.1. If a Third Party initiates a Proceeding claiming a Patent Right owned by or licensed to such Third Party is infringed by the Development, Manufacture or Commercialization of a Product, (a) Isis will have the first right, but not the obligation, to defend against any such Proceeding initiated prior to Option exercise at its sole cost and expense and (b) Roche will have the first right, but not the obligation, to defend against any such Proceeding initiated after Option exercise at its sole cost and expense. If the Party having the first right to defend against such Proceeding (the “Lead Party”) elects to defend against such Proceeding, then the Lead Party will have the sole right to direct the defense and to elect whether to settle such claim (but only with the prior written consent of the other Party, not to be unreasonably withheld, conditioned or delayed). The other Party will reasonably assist the Lead Party in defending such Proceeding and cooperate in any such litigation at the request and expense of the Lead Party. The Lead Party will provide the other Party with prompt written notice of the commencement of any such Proceeding that is of the type described in this Section 7.4, and the Lead Party will keep the other Party apprised of the progress of such Proceeding. If the Lead Party elects not to defend against a Proceeding, then the Lead Party will so notify the other Party in writing within sixty (60) days after the Lead Party first receives written notice of the initiation of such Proceeding, and the other Party (the “Step-In Party”) will have the right, but not the obligation, to defend against such Proceeding at its sole cost and expense and thereafter the Step-In Party will have the sole right to direct the defense thereof, including the right to settle such claim. In any event, the Party not defending such

Proceeding will reasonably assist the other Party and cooperate in any such litigation at the request and expense of the Party defending such Proceeding. Each Party may at its own expense and with its own counsel join any defense initiated or directed by the other Party under this Section 7.4. Each Party will provide the other Party with prompt written notice of the commencement of any such Proceeding under this Section 7.4, and such Party will promptly furnish the other Party with a copy of each communication relating to the alleged infringement that is received by such Party.

7.4.2. Discontinued Product. If a Third Party initiates a Proceeding claiming that any Patent Right or Know-How owned by or licensed to such Third Party is infringed by the Development, Manufacture or Commercialization of a Discontinued Product, Isis will have the first right, but not the obligation, to defend against and settle such Proceeding at its sole cost and expense. Roche will reasonably assist Isis in defending such Proceeding and cooperate in any such litigation at the request and expense of Isis. Each Party may at its own expense and with its own counsel join any defense directed by the other Party. Isis will provide Roche with prompt written notice of the commencement of any such Proceeding, or of any allegation of infringement of which Isis becomes aware and that is of the type described in this Section 7.4.2, and Isis will promptly furnish Roche with a copy of each communication relating to the alleged infringement received by Isis.

7.4.3. Interplay Between Enforcement of IP and Defense of Third Party Claims. Notwithstanding the provisions of Section 7.4.1 and Section 7.4.2, to the extent that a Party’s defense against a Third Party claim of infringement under this Section 7.4 involves (i) the enforcement of the other Party’s Know-How or Patent Rights, or (ii) the defense of an invalidity claim with respect to such other Party’s Know-How or Patent Rights, then, in each case, the general concepts of Section 7.5 will apply to the enforcement of such other Party’s Know-How or Patent Rights or the defense of such invalidity claim (i.e., each Party has the right to enforce its own intellectual property, except that the relevant Commercializing Party will have the initial right, to the extent provided in Section 7.5, to enforce such Know-How or Patent Rights or defend such invalidity claim, and the other Party will have a step-in right, to the extent provided in Section 7.5, to enforce such Know-How or Patent Rights or defend such invalidity claim).

7.5. Enforcement of Patents Against Competitive Infringement.

7.5.1. Duty to Notify of Competitive Infringement. If either Party learns of an infringement, unauthorized use, misappropriation or threatened infringement by a Third Party to which such Party does not owe any obligation of confidentiality with respect to any Product-Specific Patents by reason of the development, manufacture, use or commercialization of a product directed against the RNA that encodes HTT in the Field (“Competitive Infringement”), such Party will promptly notify the other Party in writing and will provide such other Party with available evidence of such Competitive Infringement; provided, however, that for

cases of Competitive Infringement under Section 7.5.7 below, such written notice will be given within ten (10) Business Days.

7.5.2. Prior to Option Exercise. For any Competitive Infringement occurring after the Effective Date but before Option exercise, Isis will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding with respect thereto, by counsel of its own choice, and Roche will have the right to be represented in that action by counsel of its own choice at its own expense, however, Isis will have the sole right to control such litigation. Isis will provide Roche with prompt written notice of the commencement of any such Proceeding, and Isis will keep Roche apprised of the progress of such Proceeding. If Isis fails to initiate a Proceeding within a period of ninety (90) days after receipt of written notice of such Competitive Infringement (subject to a ninety (90) day extension to conclude negotiations, which extension will apply only in the event that Isis has commenced good faith negotiations with an alleged infringer for elimination of such Competitive Infringement within such ninety (90) day period), Roche will have the right to initiate and control a Proceeding with respect to such Competitive Infringement by counsel of its own choice; provided that Isis will have the right to be represented in any such action by counsel of its own choice at its own expense. Notwithstanding the foregoing, Isis will at all times have the sole right to institute, prosecute, and control any Proceeding under this Section 7.5.2 to the extent involving any Isis Core Technology Patents or Isis Manufacturing and Analytical Patents.

7.5.3. Following Option Exercise. For any Competitive Infringement with respect to a Product (except for a Discontinued Product) occurring after Option exercise, so long as part of such Proceeding Roche also enforces any Patent Rights Controlled by Roche being infringed that Cover a Product, then Roche will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding with respect thereto by counsel of its own choice at its own expense, and Isis will have the right, at its own expense, to be represented in that action by counsel of its own choice, however, Roche will have the right to control such litigation. If Roche fails to initiate a Proceeding within a period of ninety (90) days after receipt of written notice of such Competitive Infringement (subject to a ninety (90) day extension to conclude negotiations, if Roche has commenced good faith negotiations with an alleged infringer for elimination of such Competitive Infringement within such ninety (90) day period), Isis will have the right to initiate and control a Proceeding with respect to such Competitive Infringement by counsel of its own choice, and Roche will have the right to be represented in any such action by counsel of its own choice at its own expense. Notwithstanding the foregoing, Isis will at all times have the sole right to institute, prosecute, and control any Proceeding under this Section 7.5.3 to the extent involving any Isis Core Technology Patents or Isis Manufacturing and Analytical Patents.

7.5.4. Joinder.

(a) If a Party initiates a Proceeding in accordance with this Section 7.5, the other Party agrees to be joined as a party plaintiff where necessary and to give the first Party reasonable assistance and authority to file and prosecute the Proceeding. Subject to Section 7.5.5, the costs and expenses of each Party incurred pursuant to this Section 7.5.4(a) will be borne by the Party initiating such Proceeding.

(b) If one Party initiates a Proceeding in accordance with this Section 7.5.4, the other Party may join such Proceeding as a party plaintiff where necessary for such other Party to seek lost profits with respect to such infringement.

11.4. Press Release; Publications; Disclosure of Agreement.

11.4.1. Public Announcements — Generally. Upon execution of this Agreement, the Parties will issue a joint press release announcing the existence of this Agreement in a form and substance agreed to in writing by the Parties. Except to the extent required to comply with Applicable Law, regulation, rule or legal process or as otherwise permitted in accordance with this Section 11.4, each Party agrees not to issue any other press release or other public statement disclosing other information relating to this Agreement or the terms of this Agreement or the transactions contemplated hereby without the prior written consent of the other Party, which consent will not be unreasonably withheld or delayed.

11.4.2. Use of Name. Except as set forth in Section 11.4.9, neither Party will use the other Party’s name in a press release or other publication without first obtaining the prior consent of the Party to be named.

11.4.3. Notice of Significant Events. Each Party will notify (no later than three Business Days after the information or results are obtained) the other Party of any significant event related to a Product (including any data, serious adverse event or regulatory advice or approval) so that the Parties may analyze the need to or desirability of publicly disclosing or reporting such event. Notwithstanding Section 11.4.1 above, any press release or other similar public communication by either Party related to a Product’s efficacy or safety data and/or results, will be submitted to the other Party for review and approval at least three Business Days in advance of such proposed public disclosure, which approval will not be unreasonably withheld or delayed.

11.4.4. Prior to Option Exercise. Prior to Option exercise, Isis will have the sole right, consistent with its practice with its other compounds and products, to issue press releases, publish, present or otherwise disclose the progress and results regarding the Products to the public; provided, that with respect to any proposed press release or other similar public communication by Isis disclosing regulatory discussions, the efficacy or safety data or clinical results related to the Products, (i) Isis will submit such proposed communication to Roche for review at least ten (10) Business Days in advance of such proposed public disclosure, (ii) Roche will have the right to review and recommend changes to such communication, and (iii) Isis will in good faith consider any changes that are timely recommended by Roche.

11.4.6. Scientific or Clinical Presentations. Regarding any proposed scientific publications related to results from any Clinical Studies, the Parties agree to use Commercially Reasonable Efforts to control public scientific disclosures of such results to prevent any adverse effect of any premature public disclosure of such results. The Parties will establish a procedure for publication review and each

Party will first submit to the other Party through the Joint Patent Committee an early draft of all such publications or presentations, at least forty-five (45) days prior to submission for publication including to facilitate the publication of any summaries of Clinical Studies data and results as required on the clinical trial registry of each respective Party. Each Party will review such proposed publication to avoid the unauthorized disclosure of a Party’s Confidential Information and to preserve the patentability of inventions arising from an R&D Plan. If, during such forty-five (45) day period, the other Party informs such Party that its proposed publication contains Confidential Information of the other Party, then such Party will delete such Confidential Information from its proposed publication. In addition, if during such forty-five (45) day period, the other Party informs such Party that its proposed publication discloses non-public inventions made by either Party in the course of the Development under this Agreement, or the public disclosure of such proposed publication may have a material adverse effect on any Patent Rights or Know-How solely owned or Controlled by such other Party, then such Party will either (i) delay such proposed publication for up to sixty (60) days from the date of such Party’s objection, to permit the timely first filing of patent application(s), or (ii) remove the identified disclosures prior to publication.

11.4.7 SEC Filings. Each Party will give the other Party a reasonable opportunity to review all material filings with the SEC describing the terms of this Agreement prior to submission of such filings, and will give due consideration to any reasonable comments by the non-filing Party relating to such filing.

12.1.1. Escalation. If any dispute occurs under this Agreement (other than a dispute regarding the construction, validity or enforcement of either Party’s Patents,

which disputes will be resolved pursuant to Section 12.2), either Party may request in writing that the dispute be referred for resolution to the Head of Roche Partnering of Roche and the COO of Isis (the “Executives”). Within thirty (30) days after such a request, the Executives will meet in person at a mutually acceptable time and location or by means of telephone or video conference to negotiate a settlement of the dispute. Each Party’s JSC representatives may participate in such meeting if desired. If the Executives fail to resolve the dispute within such thirty (30) day period, then the dispute will be referred to binding arbitration under Section 12.1.2.

12.4. Assignment and Successors. Neither this Agreement nor any obligation of a Party hereunder may be assigned by either Party without the consent of the other, except that each Party may assign this Agreement and the rights, obligations and interests of such Party, in whole or in part, without the other Party’s consent, to any of its Affiliates, to any purchaser of all or substantially all of its assets or all or substantially all of its assets to which this Agreement relates or to any successor corporation resulting from any merger, consolidation, share exchange or other similar transaction; provided, if a Party transfers or assigns this Agreement to [***] described in this Agreement, then such transferring Party (or such Affiliate) (“Transferring Party”), will [***] that the Transferring Party is obligated to pay to the non-transferring Party (“Non-Transferring Party”) under ARTICLE 6 for the taxes withheld such that the Non-Transferring Party receives [***] assignment. In addition, Isis may assign or transfer its rights to receive payments under this Agreement (but no liabilities), without Roche’s consent, to an Affiliate or to a Third Party in connection with a payment factoring transaction. Any purported assignment or transfer made in contravention of this Section 12.4 will be null and void.

In such

event the Party so failing or delaying will immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice will be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled for up to a maximum of ninety (90) days, after which time the Parties will negotiate in good faith any modifications of the terms of this Agreement that may be necessary to arrive at an equitable solution, unless the Party giving such notice has set out a reasonable timeframe and plan to resolve the effects of such force majeure and executes such plan within such timeframe. To the extent possible, each Party will use reasonable efforts to minimize the duration of any force majeure.

12.7. Notices. Any notice or request required or permitted to be given under or in connection with this Agreement will be deemed to have been sufficiently given if in writing and personally delivered or sent by certified mail (return receipt requested), facsimile transmission (receipt verified), or overnight express courier service (signature required), prepaid, to the Party for which such notice is intended, at the address set forth for such Party below:
