6.8.1.

Existing Ionis In-License Agreements.

(a)

Certain of the Licensed Technology Controlled by Ionis as of the Effective Date licensed to Biogen under Section 4.1.1 is in-licensed or acquired by Ionis under the agreements with Third Party licensors or sellers listed on Schedule 6.8.1 or in a separate written agreement between the Parties (all such license or purchase agreements being the “Ionis In-License Agreements”), and certain milestone or royalty payments and license maintenance fees may become payable by Ionis to such Third Parties under the Ionis In-License Agreements based on the Development and Commercialization of a Product by Biogen under this Agreement.

(b)

Any payment obligations arising under the Ionis In-License Agreements as existing on the Effective Date, as they apply to Products, will be paid by [***] as [***].

6.8.2.

New Third Party Agreements Prior to Development Candidate Designation.

(a)

If, prior to the designation of a Development Candidate under Section 1.4.2(b) with respect to a Collaboration Program, either Party becomes aware of Third Party Patent Rights or Know-How that are necessary to Develop, Manufacture or Commercialize a Product under such Collaboration Program, Ionis will seek to obtain a sublicensable license under such Third Party Patent Rights or Know-How. If Ionis obtains such a license, such Third Party Patent Rights or Know-How shall automatically be deemed “Licensed Technology” under this Agreement, and any payment obligations arising under such license, as they apply to Products, will be paid by [***] as [***]. If any such Third Party Patent Right would have been considered an Ionis Product-Specific Patent had Ionis Controlled such Patent Right on the Effective Date, then Biogen shall have the right to review and comment on the terms of any license with respect to such Third Party Patent Right prior to execution thereof, and Ionis shall only enter into such license in the final form approved by Biogen (such approval not to be unreasonably withheld, delayed or conditioned).

(b)

If Ionis fails to obtain such a license under such Third Party Patent Rights or Know-How, then Ionis will so notify Biogen, and Biogen may seek to obtain such a Third Party license. If Biogen obtains such a Third Party license, then, subject to Section 6.6.2(d), Biogen may offset an amount equal to [***]% of [***] against [***] (including pursuant to Biogen’s right to carry any excess amounts forward to subsequent Calendar Quarters as set forth in Section 6.6.2(d)).

New Third Party Agreements Following Development Candidate Designation.

(a)

Additional Ionis IP.

(i)

If, following the designation of a Development Candidate under Section 1.4.2(b) with respect to a Collaboration Program, either Party becomes aware of any Additional Core IP or any Patent Right or Know-How that would have been considered an Ionis Manufacturing and Analytical Patent or Ionis Manufacturing and Analytical Know-How had Ionis Controlled such Patent Right or Know-How on the Effective Date (such Patent Rights and Know-How, “Additional Manufacturing IP” and, collectively with the Additional Core IP, the “Additional Ionis IP”), Ionis will have the first right, but not the obligation, to negotiate with and obtain a license from the Third Party Controlling such Additional Ionis IP. If Ionis obtains such a Third Party license, Ionis will include such Additional Ionis IP in the license granted to Biogen under Section 4.1.1, and any financial obligations under such Third Party agreement will be paid solely by [***] as [***].

(ii)

If, however, Ionis elects not to obtain such a license to such Additional Ionis IP, Ionis will so notify Biogen, and Biogen may obtain such a Third Party license. If Biogen obtains such a Third Party license, then, subject to Section 6.6.2(d), Biogen may offset an amount equal to [***]% of [***] against [***] of this Agreement [***] (including pursuant to Biogen’s right to carry any excess amounts forward to subsequent Calendar Quarters as set forth in Section 6.6.2(d)).

(iii)

If it is unclear whether certain Third Party Patent Rights or Know-How constitute Additional Ionis IP, Ionis will send written notice to such effect to Biogen, and the Parties will engage a mutually agreed upon 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 Ionis 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 Biogen is permitted to [***]. The costs of any Third Party expert engaged under this Section 6.8.3(a)(iii) will be paid by the Party against whose position the Third Party lawyer’s determination is made.

(iv)

If a Third Party Controlling Additional Ionis IP is awarded a judgment from a court of competent jurisdiction arising from its claim against Biogen asserting that [***], Biogen will be permitted to (i) [***], and (ii) [***] (in each case ((A) and (B)), subject to Biogen’s right to carry any excess amounts forward to subsequent Calendar Quarters as set forth in Section 6.6.2(d)).

(b)

Other Intellectual Property. If following the designation of a Development Candidate under Section 1.4.2(b) with respect to a Collaboration Program, either Party becomes aware of Third Party Patent Rights or Know-How that would be [***] Develop, Manufacture or Commercialize a Product under such Collaboration Program and that do not constitute Additional Ionis IP [***], then such Party will promptly provide the other Party with written notice of any such Third Party Patent Rights or Know-How, and Biogen will have the sole right, but not the obligation, to negotiate with and obtain a license from the Third Party Controlling such Third Party Patent Rights or Know-How. Except as expressly set forth in Section 7.1.3(b), if Biogen obtains such a Third Party license, and subject to Section 6.6.2(d), Biogen may offset an amount equal to [***]% of [***] against [***] (including pursuant to Biogen’s right to carry any excess amounts forward to subsequent Calendar Quarters as set forth in Section 6.6.2(d)); provided, however, [***].

Payments.

6.9.1.

Commencement. Beginning with the Calendar Quarter in which the First Commercial Sale for a Product is made and for each Calendar Quarter thereafter, Biogen will make royalty payments to Ionis under this Agreement within [***] following the end of each such Calendar Quarter. Each royalty payment will be accompanied by a report, summarizing Net Sales for Products during the relevant Calendar Quarter and the calculation of royalties due thereon, including country, units, sales price and the exchange rate used and the aggregate reduction to gross sales to arrive at Net Sales. Following the end of the first full Calendar Quarter subsequent to First Commercial Sale in a Major Market of any Product (but not in any subsequent Calendar Quarter unless there is a material change in the amount of any reduction to gross sales or the methodology used by Biogen to calculate any such reduction), Biogen will also include in such report a description of the reductions to gross sales to arrive at Net Sales, broken down by each category of reduction listed in clauses (a) through (d) of the definition of “Net Sales” and a non-binding qualitative analysis describing how Biogen anticipates such reductions may fluctuate over time. If no royalties are payable in respect of a given Calendar Quarter, Biogen will submit a written royalty report to Ionis 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 is made and for each Calendar Quarter thereafter, within [***] following the end of each such Calendar Quarter, Biogen will provide Ionis a [***] report estimating the total Net Sales of, and royalties payable to Ionis for, Products projected for such Calendar Quarter.

Confidential

6.9.2.

Mode of Payment. All payments under this Agreement will be (i) payable in full in United States 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 Ionis in writing, and (iii) irrevocable, non-refundable and non-creditable. Whenever for the purposes of calculating the royalties payable under this Agreement conversion from any foreign currency will be required, all amounts will first be calculated in the currency of sale and then converted into United States dollars by applying the monthly average rate of exchange as utilized by Biogen, in accordance with GAAP, fairly applied and as employed on a consistent basis throughout Biogen’s operations.

6.9.3.

Records Retention. Commencing with the First Commercial Sale of a Product, Biogen 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 Ionis to confirm the accuracy of the Net Sales or royalties paid by Biogen hereunder.

6.10.

Audits. After Biogen is granted a license under Section 4.1.1 for a particular Product, during the Agreement Term and for a period of [***] thereafter, at the request and expense of Ionis, Biogen will permit an independent certified public accountant of nationally recognized standing appointed by Ionis, at reasonable times and upon reasonable notice, but in no case more than [***], to examine such records as may be necessary for the purpose of verifying the calculation and reporting of Net Sales (including for purposes of determining if a milestone is due under Section 6.4) and the correctness of any royalty payment made under this Agreement for any period within the preceding [***]. As a condition to examining any records of Biogen, such auditor will sign a nondisclosure agreement reasonably acceptable to Biogen in form and substance. Any and all records of Biogen examined by such independent certified public accountant will be deemed Biogen’s Confidential Information. Upon completion of the audit, the accounting firm will provide both Biogen and Ionis with a written report disclosing whether the royalty payments made by Biogen are correct or incorrect and the specific details concerning any discrepancies (“Audit Report”). If, as a result of any inspection of the books and records of Biogen, it is shown that Biogen’s payments under this Agreement were less than the royalty amount (or sales milestone amount) which should have been paid, then Biogen will make all payments required to be made by paying Ionis the difference between such amounts to eliminate any undisputed discrepancy revealed by said inspection within 45 days of receiving the Audit Report, with interest calculated in accordance with Section 6.12. If, as a result of any inspection of the books and records of Biogen, it is shown that Biogen’s payments under this Agreement were greater than the royalty amount which should have been paid, [***]; provided, however, that if [***]. Ionis will pay for such audit, except that if Biogen is found to have underpaid Ionis by more than [***]% of the amount that should have been paid, Biogen will reimburse Ionis’ reasonable costs of the audit.

Taxes.

6.11.1.

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.

6.11.2.

Withholding Tax. The Parties agree to cooperate with one another and use reasonable efforts to lawfully avoid or reduce tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by the paying Party to the receiving Party under this Agreement. To the extent the paying Party is required to deduct and withhold taxes, interest or penalties 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 entitled to do so.

6.11.3.

Tax Cooperation. Ionis will provide Biogen with any and all tax forms that may be reasonably necessary in order for Biogen to lawfully not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Following Biogen’s timely receipt of such tax forms from Ionis, Biogen 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. Ionis will provide any such tax forms to Biogen upon request and in advance of the due date. Each Party will provide the other with reasonable assistance to determine if any taxes are applicable to payments under this Agreement and 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 6.11.

The provisions of this Section 6.11 are to be read in conjunction with the provisions of Section 12.4 below.

6.12.

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) the rate announced by Bank of America (or its successor) as its prime rate in effect on the date that such payment would have been first due plus 1% or (ii) the maximum rate permissible under Applicable Law.

7.1.3.

Joint Patent Committee.

(a)

The Parties will establish a Joint Patent Committee (the “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, including the preparation of the intellectual property assessment to be included in each Development Candidate Data Package and the activities set forth in this ARTICLE 7, and will cooperate with respect to any such activities. Ionis’ obligation to participate in the JPC will terminate upon Biogen’s exercise of (or the expiration or termination of) the last Option. Thereafter, Ionis will have the right, but not the obligation, to participate in JPC meetings. In preparing the intellectual property assessment to be included in each Development Candidate Data Package, the JPC will discuss a strategy with regard to intellectual property considerations with respect to the applicable Development Candidate, including prosecution and maintenance, defense and enforcement of Ionis Product-Specific Patents that would be or are licensed to Biogen under Section 4.1.1 in connection with a Product and Biogen Product-Specific Patents, defense against allegations of infringement of Third Party Patent Rights, and licenses to Third Party Patent Rights or Know-How, in each case to the extent such matter would be reasonably likely to have a material impact on this Agreement or the Original Agreement or the licenses granted hereunder or thereunder, which strategy will be considered in good faith by the Party entitled to prosecute, enforce or defend such Patent Rights, as applicable, hereunder, but will not be binding on such Party.

(b)

Ionis or Biogen (as applicable) will provide the JPC with notice of any Know-How or Patent Rights discovered, developed, invented or created jointly by such Party and a Third Party in the performance of activities under the ASO Development Candidate Identification Plan or activities under the preclinical toxicology strategy for a Collaboration Program, or solely by a Third Party performing activities under the ASO Development Candidate Identification Plan or activities under the preclinical toxicology strategy for a Collaboration Program on such Party’s behalf (such Know-How and Patent Rights, the “Collaborator IP”) promptly after such Party receives notice or otherwise becomes aware of the existence of such Collaborator IP. The JPC will determine whether any such Collaborator IP would be infringed by the Development, registration, Manufacture or Commercialization of the applicable Development Candidate or any Compound under consideration for potential designation as a Development Candidate. If the JPC (or independent patent counsel engaged pursuant to this Section 7.1.3(b)) determines that any Collaborator IP would be infringed by such Development, registration, Manufacture or Commercialization, [***]; provided that, [***].

Confidential

Notwithstanding any provision to the contrary in this Agreement, if Collaborator IP arises from activities performed by a Third Party under the ASO Development Candidate Identification Plan or activities under the preclinical toxicology strategy for a Collaboration Program, then any payment obligations arising under the applicable [***] based on the Development or Commercialization of a Product will be paid as follows: [***].

With respect to any such Collaborator IP [***], Biogen will have the right in accordance with Section 4.1.5 to elect to exclude any such Collaborator IP from the applicable license granted to Biogen under Section 4.1.1 by providing Ionis written notice prior to Option exercise. If, prior to the date the applicable license under Section 4.1.1 is granted hereunder, Biogen provides Ionis with such a written notice to exclude certain of such Collaborator IP from such license, such Collaborator IP will not be included in the Licensed Technology licensed with respect to the applicable Products under this Agreement. If Biogen does not provide Ionis with such a written notice to exclude such Collaborator IP prior to the date the applicable license under Section 4.1.1 is granted hereunder, such Collaborator IP (and any Third Party Obligations to the extent applicable to Products) will be included in the Licensed Technology licensed with respect to the applicable Products under this Agreement.

In case of a dispute in the JPC over whether any Collaborator IP would be infringed by the Development, registration, Manufacture or Commercialization of the applicable Development Candidate or any Compound under consideration for potential designation as the Development Candidate, at the non-contracting Party’s request, 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, taking into account any existing prior art. The decision of such independent patent counsel will be binding on the Parties. Expenses of such patent counsel will be borne by the non-contracting Party.

(c)

In addition, the JPC will be responsible for the determination of inventorship of Program Patents in accordance with United States patent laws. In case of a dispute in the JPC (or otherwise between Ionis and Biogen) over inventorship of Program Patents, if the JPC cannot resolve such dispute, 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 JPC 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, including the JPC’s policies for replacement of JPC members, and the location of meetings, which will be codified in the written minutes of the first JPC meeting. To the extent reasonably requested by either Party, the JPC will solicit the involvement of more senior members of their respective legal departments (up to the most senior intellectual property attorney, where appropriate) with respect to critical issues, and may escalate issues to the Executives for input and resolution pursuant to Section 12.1. Each Party’s representatives on the JPC 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. The Parties acknowledge and agree that it is critical to the success of the Products under this Agreement and to the continued success of Spinraza^®, that the Parties closely coordinate the Prosecution and Maintenance of any Patent Rights for Products under this Agreement with the Prosecution and Maintenance of the Patent Rights for Spinraza^® under the Original Agreement. Such efforts will include Ionis’ coordination with Biogen prior to Option exercise of Ionis’ Prosecution and Maintenance of the Ionis Product-Specific Patents and any Jointly-Owned Program Patents Covering Products.

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 the applicable 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. On a Collaboration Program-by-Collaboration Program basis, until the earlier of the date Biogen is granted the license under Section 4.1.1 and the expiration or termination of Biogen’s right to be granted such license, Ionis will use Commercially Reasonable Efforts to diligently Prosecute and Maintain all Ionis Product-Specific Patents and any Jointly-Owned Program Patents Covering Products, in each case to the extent that Ionis has the right to Prosecute and Maintain such Patent Rights.

Confidential

7.2.2.

Licensed Patents and Biogen Patents.

(a)

Licensed Patents In General. Prior to the date Biogen is granted the license under Section 4.1.1 for a Product, Ionis will control and be responsible for all aspects of the Prosecution and Maintenance of all Licensed Patents that are the subject of such license grant, subject to Section 7.2.2(b) and Section 7.2.3; provided if Biogen reasonably believes that Ionis’ planned Prosecution and Maintenance of a Product-Specific Patent that would be subject to a license granted to Biogen under Section 4.1.1, is reasonably likely to adversely affect the scope, validity or enforceability of a Product-Specific Patent Covering Spinraza^® under the Original Agreement, then the Parties through the JPC will try to develop a strategy that maximizes the protection for the potential Development Candidates under this Agreement but is not reasonably likely to adversely affect the scope, validity or enforceability of a Product-Specific Patent Covering Spinraza^® under the Original Agreement. If the Parties cannot agree on such a strategy then either Party may refer the matter to (and the Parties will engage) a mutually agreed upon independent Third Party intellectual property lawyer with expertise in the patenting of ASOs, and appropriate professional credentials in the relevant jurisdiction, to determine if Ionis’ planned Prosecution and Maintenance is reasonably likely to adversely affect the scope, validity or enforceability of a Product-Specific Patent Covering Spinraza^® under the Original Agreement. If such independent Third Party intellectual property lawyer believes Ionis’ planned Prosecution and Maintenance is reasonably likely to adversely affect the scope, validity or enforceability of a Product-Specific Patent Covering Spinraza^® under the Original Agreement, such lawyer will propose a strategy to maximize the protection for the potential Development Candidates under this Agreement but is not reasonably likely to adversely affect the scope, validity or enforceability of a Product-Specific Patent Covering Spinraza^®. The determination and recommended strategy of the Third Party expert engaged under this Section 7.2.2(a) will be binding on the Parties solely for purposes of setting the Prosecution and Maintenance strategy for the relevant Product-Specific Patent under this Agreement. The costs of any Third Party expert engaged under this Section 7.2.2(a) will be paid by the Party against whose position the Third Party lawyer’s determination is made. During the Agreement Term, Ionis will control and be responsible for all aspects of the Ionis Core Technology Patents and Ionis Manufacturing and Analytical Patents.

(b)

Licensed Patents After License Grant. After the date Biogen is granted the license under Section 4.1.1 for a Product, Biogen will control and be responsible for all aspects of the Prosecution and Maintenance of all the Ionis Product-Specific Patents and Jointly-Owned Program Patents that are the subject of such license to the same extent Ionis had the right to control and was responsible for such Prosecution and Maintenance immediately prior to such license.

(c)

Biogen Patents. During the Agreement Term, Biogen will control and be responsible for all aspects of the Prosecution and Maintenance of all Biogen Patents, subject to Section 7.2.4.

Confidential

7.2.3.

Jointly-Owned Program Patents. Ionis will control and be responsible for all aspects of the Prosecution and Maintenance of Jointly-Owned Program Patents that do not Cover Products. Prior to the date Biogen is granted the license under Section 4.1.1, Ionis will control and be responsible for all aspects of the Prosecution and Maintenance of Jointly-Owned Program Patents Covering Products that are the subject of such license. After the date Biogen is granted the license under Section 4.1.1, Biogen will control and be responsible for all aspects of the Prosecution and Maintenance of Jointly-Owned Program Patents Covering Products that are the subject of such license.

7.2.4.

Other Matters Pertaining to Prosecution and Maintenance of Patents.

(a)

Each Party will keep the other Party informed through the JPC as to material developments with respect to the Prosecution and Maintenance of the Ionis Core Technology Patents, Product-Specific Patents and Jointly-Owned Program 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 Biogen elects (a) not to file and prosecute patent applications for the Jointly-Owned Program Patents, Ionis Product-Specific Patents that have been licensed or assigned to Biogen under this Agreement or Biogen Product-Specific Patents (“Biogen-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 Biogen-Prosecuted Patent in a particular country, or (c) not to file and prosecute patent applications for the Biogen-Prosecuted Patent in a particular country following a written request from Ionis to file and prosecute in such country, then Biogen will so notify Ionis promptly in writing of its intention (including a reasonably detailed rationale for doing so) in good time to enable Ionis to meet any deadlines by which an action must be taken to establish or preserve any such Patent Right in such country; and except as set forth in Section 7.2.4(c), Ionis will have the right, but not the obligation, to file, prosecute, maintain, enforce, or otherwise pursue such Biogen-Prosecuted Patent in the applicable country at its own expense with counsel of its own choice. In such case, Biogen will cooperate with Ionis to file for, or continue to Prosecute and Maintain or enforce, or otherwise pursue such Biogen-Prosecuted Patent in such country in Ionis’ own name, but only to the extent that Biogen is not required to take any position with respect to such abandoned Biogen-Prosecuted Patent that would be reasonably likely to adversely affect the scope, validity or enforceability of any of the other Patent Rights being prosecuted and maintained by Biogen under this Agreement. Notwithstanding anything to the contrary in this Agreement, if Ionis assumes responsibility for the Prosecution and Maintenance of any such Biogen-Prosecuted Patent under this Section 7.2.4(b), Ionis will have no obligation to notify Biogen if Ionis intends to abandon such Biogen-Prosecuted Patent.

Confidential

(c)

Notwithstanding Section 7.2.4(b) above, if, after having consulted with outside counsel, Biogen reasonably determines that filing or continuing to prosecute a patent application in a particular country for a Biogen-Prosecuted Patent (the “Conflicting Patent Right”) is reasonably likely to adversely affect the scope, validity or enforceability of a patent application or issued patent in a particular country for another Biogen-Prosecuted Patent (the “Superior Patent Right”), in each case where both the Conflicting Patent Right and the Superior Patent Right if issued would meet the criteria set forth in clause (i) of Section 6.6.2(a), then so long as Biogen continues to Prosecute and Maintain the Superior Patent Right in accordance with this Agreement, Ionis will not have the right under Section 7.2.4(a) above to file or prosecute the Conflicting Patent Right.

(d)

If, during the Agreement Term, Ionis intends to abandon any Ionis Product-Specific Patent for which Ionis is responsible for Prosecution and Maintenance without first filing a continuation or substitution, then, if Biogen’s right to obtain a license under Section 4.1.1 to such Ionis Product-Specific Patent has not expired or terminated, Ionis will notify Biogen of such intention at least [***] days before such Patent Right will become abandoned, and Biogen 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. Notwithstanding anything to the contrary in this Agreement, if Biogen assumes responsibility for the Prosecution and Maintenance of any such Ionis Product-Specific Patent under this Section 7.2.4(d), Biogen will have no obligation to notify Ionis if Biogen intends to abandon such Ionis Product-Specific Patent.

(e)

The Parties, through the JPC, will cooperate in good faith to determine if and when any divisional or continuation applications will be filed with respect to any Program 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.

Confidential

(f)

If the Party responsible for Prosecution and Maintenance pursuant to Section 7.2.3 intends to abandon such Jointly-Owned Program Patent without first filing a continuation or substitution, then such Party will notify the other Party of such intention at least [***] days before such Jointly-Owned Program 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 Program Patents. If a Party assumes responsibility for the Prosecution and Maintenance of any such Jointly-Owned Program Patents under this Section 7.2.4(f), such Party will have no obligation to notify the other Party of any intention of such Party to abandon such Jointly-Owned Program Patents.

(g)

In addition, the Parties will consult, through the JPC, 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.

7.4.	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) Ionis will have the first right, but not the obligation, to defend against any such Proceeding initiated prior to the date Biogen is granted the license under Section 4.1.1 at its sole cost and expense, and (b) Biogen will have the first right, but not the obligation, to defend against any such Proceeding initiated after the date Biogen is granted the license under Section 4.1.1 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 [***] 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, Ionis will have the first right, but not the obligation, to defend against and settle such Proceeding at its sole cost and expense. Biogen will reasonably assist Ionis in defending such Proceeding and cooperate in any such litigation at the request and expense of Ionis. Each Party may at its own expense and with its own counsel join any defense directed by the other Party. Ionis will provide Biogen with prompt written notice of the commencement of any such Proceeding, or of any allegation of infringement of which Ionis becomes aware and that is of the type described in this Section 7.4.2, and Ionis will promptly furnish Biogen with a copy of each communication relating to the alleged infringement received by Ionis.

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 (e.g., a counterclaim of infringement), 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).

7.4.4.

Effect of Defense of Third Party Claims on Original Agreement. Notwithstanding anything to the contrary in this Section 7.4, if, prior to the date Biogen is granted the license under Section 4.1.1, Biogen reasonably believes that Ionis’ election to defend against a Proceeding (and Ionis’ strategy with respect to such defense) under this Section 7.4 would be reasonably likely to adversely affect a Product-Specific Patent Covering Spinraza^® under the Original Agreement, then the Parties through the JPC will try to develop a strategy with respect to such defense that maximizes the protection for the potential Development Candidates under this Agreement but is not reasonably likely to adversely affect the Product-Specific Patent Covering Spinraza^® under the Original Agreement. If the Parties cannot agree on such a strategy then either Party may refer the matter to (and the Parties will engage) a mutually agreed upon independent Third Party intellectual property lawyer with expertise in the patenting of ASOs, and appropriate professional credentials in the relevant jurisdiction, to determine if Ionis’ planned defense against a Proceeding (and Ionis’ strategy with respect thereto) is reasonably likely to adversely affect a Product-Specific Patent Covering Spinraza^® under the Original Agreement. If such independent Third Party intellectual property lawyer believes Ionis’ planned defense against a Proceeding (and Ionis’ strategy with respect thereto) is reasonably likely to adversely affect a Product-Specific Patent Covering Spinraza^® under the Original Agreement, such lawyer will propose a strategy to maximize the protection for the potential Development Candidates under this Agreement but is not reasonably likely to adversely affect a Product-Specific Patent Covering Spinraza^®. The determination and recommended strategy of the Third Party expert engaged under this Section 7.4.4 will be binding on the Parties solely for purposes of setting the defense strategy against the relevant Proceeding under this Agreement. The costs of any Third Party expert engaged under this Section 7.4.4 will be paid by the Party against whose position the Third Party lawyer’s determination is made.

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 SMN 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 10 days.

7.5.2.

Prior to License Grant.

(a)

For any Competitive Infringement with respect to a Product occurring after the Effective Date but before the date Biogen is granted the license under Section 4.1.1, Ionis 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 Biogen will have the right to be represented in that action by counsel of its own choice at its own expense, provided, however, Ionis will have the sole right to control such litigation; and provided, further, that, if Biogen reasonably believes that Ionis’ election to institute, prosecute, and control a Proceeding with respect to such Competitive Infringement (and Ionis’ strategy with respect thereto) under this Section 7.5.2 would be reasonably likely to adversely affect a Product-Specific Patent Covering Spinraza^® under the Original Agreement, then the Parties through the JPC will try to develop a strategy that maximizes the protection for the potential Development Candidates under this Agreement but is not reasonably likely to adversely affect a Product-Specific Patent Covering Spinraza^® under the Original Agreement. If the Parties cannot agree on such a strategy then either Party may refer the matter to (and the Parties will engage) a mutually agreed upon independent Third Party intellectual property lawyer with expertise in the patenting of ASOs, and appropriate professional credentials in the relevant jurisdiction, to determine if Ionis’ planned enforcement against a Competitive Infringement (and Ionis’ strategy with respect thereto) is reasonably likely to adversely affect a Product-Specific Patent Covering Spinraza^® under the Original Agreement. If such independent Third Party intellectual property lawyer believes Ionis’ planned enforcement against a Competitive Infringement (and Ionis’ strategy with respect thereto) is reasonably likely to adversely affect a Product-Specific Patent Covering Spinraza^® under the Original Agreement, such lawyer will propose a strategy to maximize the protection for the potential Development Candidates under this Agreement but is not reasonably likely to adversely affect a Product-Specific Patent Covering Spinraza^®. The determination and recommended strategy of the Third Party expert engaged under this Section 7.5.2 will be binding on the Parties solely for purposes of setting the enforcement strategy against the relevant Competitive Infringement under this Agreement. The costs of any Third Party expert engaged under this Section 7.5.2 will be paid by the Party against whose position the Third Party lawyer’s determination is made.

Confidential

(b)

Ionis will provide Biogen with prompt written notice of the commencement of any such Proceeding, and Ionis will keep Biogen apprised of the progress of such Proceeding. If Ionis fails to initiate a Proceeding within a period of 90 days after receipt of written notice of such Competitive Infringement (subject to a 90 day extension to conclude negotiations, which extension will apply only in the event that Ionis has commenced good faith negotiations with an alleged infringer for elimination of such Competitive Infringement within such 90 day period), Biogen will have the right to initiate and control a Proceeding with respect to such Competitive Infringement by counsel of its own choice; provided that Ionis will have the right to be represented in any such action by counsel of its own choice at its own expense. Notwithstanding the foregoing, Ionis 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 Ionis Core Technology Patents or Ionis Manufacturing and Analytical Patents.

7.5.3.

Following License Grant. For any Competitive Infringement with respect to a particular Product (except for a Discontinued Product) occurring after the date Biogen is granted the license under Section 4.1.1, so long as part of such Proceeding Biogen also enforces any Patent Rights Controlled by Biogen (including any Ionis Product-Specific Patents assigned by Ionis to Biogen under this Agreement) being infringed that Cover the Product, then Biogen 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 Ionis will have the right, at its own expense, to be represented in that action by counsel of its own choice; however, Biogen will have the right to control such litigation. If Biogen fails to initiate a Proceeding within a period of 90 days after receipt of written notice of such Competitive Infringement (subject to a 90 day extension to conclude negotiations, if Biogen has commenced good faith negotiations with an alleged infringer for elimination of such Competitive Infringement within such 90 day period), Ionis will have the right to initiate and control a Proceeding with respect to such Competitive Infringement by counsel of its own choice, and Biogen will have the right to be represented in any such action by counsel of its own choice at its own expense. Notwithstanding the foregoing, Ionis 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 Ionis Core Technology Patents or Ionis Manufacturing and Analytical Patents.

7.5.7.

35 USC 271(e)(2) Infringement. Notwithstanding anything to the contrary in this Section 7.5, solely with respect to Licensed Patents that have not been assigned to Biogen under this Agreement for a Competitive Infringement under 35 USC 271(e)(2), the time period set forth in Section 7.5.2 during which a Party will have the initial right to bring a Proceeding will be shortened to a total of 25 days, so that, to the extent the other Party has the right, pursuant to such Section to initiate a Proceeding if the first Party does not initiate a Proceeding, such other Party will have such right if the first Party does not initiate a Proceeding within 25 days after such first Party’s receipt of written notice of such Competitive Infringement.

7.6.	Other Infringement.

7.6.1.

Jointly-Owned Program Patents. With respect to the infringement of a Jointly-Owned Program Patent which is not a Competitive Infringement, the Parties will cooperate in good faith to bring suit together against such infringing party or the Parties may decide to permit one Party to solely bring suit. Any damages or other monetary awards recovered with respect to a Proceeding brought pursuant to this Section 7.6.1 will be shared as follows: (i) the amount of such recovery will first be applied to the Parties’ reasonable out-of-pocket costs incurred in connection with such Proceeding (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses); (ii) any remaining proceeds constituting direct damages will be [***], and (iii) any remaining proceeds constituting punitive or treble damages will be allocated as follows: (A) if the Parties jointly initiate a Proceeding pursuant to this Section 7.6.1, [***]; and (B) if only one Party initiates the Proceeding pursuant to this Section 7.6.1, such Party will receive [***]% of such proceeds and the other Party will receive [***]% of such proceeds.

If, after Option exercise, Ionis materially breaches this Agreement and fails to cure such breach within the time periods set forth under Section 10.2.4(a) or Section 10.2.5(a), and Biogen does not wish to terminate this Agreement in its entirety (an “Ionis Breach Event”), then, in addition to any other remedies Biogen may have under this Agreement or otherwise, Biogen will have the right to do any or all of the following in Biogen’s discretion solely with respect to the Collaboration Programs that are the subject of the Ionis Breach Event:

Confidential

(i)

terminate Ionis’ right to participate in the JPC, which will be disbanded (except to the extent it is performing activities under an Ionis/Biogen Additional Agreement);

(ii)

terminate Ionis’ participation in any ongoing research and development programs under the applicable Collaboration Program and Biogen’s funding obligations associated therewith;

(iii)

solely make all decisions required or permitted to be made by the JPC or the Parties collectively under this Agreement in connection with the Development and Commercialization of the applicable Product; provided, however, that Biogen will not have the right to create any obligations or incur any liabilities for or on behalf of Ionis;

(iv)

exclude Ionis from all discussions with Regulatory Authorities regarding applicable Products, except to the extent Ionis’ participation is required by a Regulatory Authority or is otherwise reasonably necessary to comply with Applicable Law;

(v)

terminate Biogen’s obligation to make further disclosures of Know-How or other information to Ionis pursuant to this Agreement related to the applicable Products, including pursuant to Section 4.9 and Section 5.3.2, other than reports required by Section 6.9.1, Section 10.4.4 (if applicable), and as reasonably required to permit Ionis to perform its obligations under this Agreement; provided such remedy will not limit or diminish the scope of any licenses granted by Biogen to Ionis under this Agreement; and

(vi)

if Ionis has not completed the activities that are its responsibility under the Collaboration Programs, then Biogen may, but will not be obligated to, assume all responsibility for all such activities that would have otherwise been Ionis’ responsibility under this Agreement.

Ionis will cooperate with the foregoing and provide to Biogen and its Third Party contractors all Know-How, assistance, assignments and other support reasonably requested to assist Biogen in assuming complete responsibility for the Development and Manufacture of the Products in an efficient and orderly manner.

Confidential

(b)

Biogen’s Right of Setoff. If there is an [***] and Biogen does not wish to [***], then, in addition to any other remedies Biogen may have under this Agreement or otherwise, Biogen may setoff against any amounts owed to Ionis pursuant to ARTICLE 6 (Financial Provisions) solely with respect to the Collaboration Program that is the subject of the Ionis Breach Event [***] (the “Setoff Amount”). If Biogen exercises its setoff right under this Section 10.4.5(b), Biogen will provide Ionis with a written certificate, signed by Biogen’s Chief Financial Officer, certifying that the amount setoff by Biogen represents [***]. Notwithstanding the foregoing, if Ionis notifies Biogen in writing (a “Setoff Dispute Notice”) that it disputes Biogen’s assertion that Ionis is in material breach of this Agreement or the amount setoff by Biogen (a “Setoff Dispute”), then (i) both Parties will participate in the dispute resolution process set forth on Schedule 10.4.5(b), and (ii) pending the Parties' agreement regarding the appropriate setoff (if any) or a determination by the Advisory Panel of the proper amount that Biogen may setoff (if any) in accordance with Schedule 10.4.5(b), Biogen will pay the Setoff Amount into an interest-bearing escrow account established for the purpose at a bank. If the Parties cannot settle their dispute by mutual agreement, then, in accordance with Schedule 10.4.5(b) the Advisory Panel will determine (1) the amount (if any) that Biogen may setoff against future payments solely with respect to the Collaboration Program that is the subject of the Ionis Breach Event to Ionis going forward, and (2) whether any portion of the escrow account should be released to Ionis or returned to Biogen, provided that any decision or determination by the Advisory Panel (a “Panel Decision”) will not be treated as an arbitral award but will be binding on the Parties until and unless a court of competent jurisdiction (the “Trial Court”) has determined in a judgment regarding some or all of the issues decided in the Panel Decision, and in any Action contemplated by the next sentence hereof the Trial Court will determine the facts and the law de novo, and will give a Panel Decision only such persuasive effect, if any, that after review of all of the facts and the law presented to the Trial Court by the Parties, the Trial Court deems appropriate, provided, that the escrow agent will comply with a Panel Decision that determines that any portion of the escrow account should be released to Ionis or returned to Biogen. If it is determined in a judgment by the Trial Court that Ionis owes Biogen any damages, then, during the pendency of any appeal of the Trial Court’s decision (or, if the Trial Court’s decision is not appealed, until Biogen recoups such amount), Biogen may setoff against any future payments solely with respect to the Collaboration Programs that are the subject of the Ionis Breach Event to Ionis under this Agreement the amount of any such damages not paid by Ionis. If it is determined in a Trial Court that Biogen has setoff an amount that exceeds the amount of losses, damages and expenses actually incurred by Biogen as a result of Ionis’ breach of this Agreement, then Biogen will promptly pay Ionis the amount of such excess, plus interest on such amount as provided for in Section 6.12 (Interest), with interest accruing from the time Biogen applied such excess setoff. If, with respect to a Setoff Dispute, Ionis provides a Setoff Dispute Notice to Biogen and Biogen fails to do any of the following: (X) appoint a member of the Advisory Panel to the extent required in Section 2 of Schedule 10.4.5(b); (Y) meet with the Advisory Panel as required in Section 3 of Schedule 10.4.5(b); or (Z) pay the Setoff Amount into an interest-bearing escrow account established for the purpose at a bank, then Biogen will forfeit its right to set off under this Section 10.4.5(b) and Schedule 10.4.5(b) with respect to any and all Setoff Disputes.

10.4.6.

Transition Services. In the case where (i) Biogen terminates this Agreement in its entirety under Section 10.2.1 (Biogen’s Termination for Convenience) or (ii) Ionis terminates this Agreement in its entirety under Section 10.2.4(b) (Ionis’ Right to Terminate) or Section 10.2.5 (Remedies for Failure to Use Commercially Reasonable Efforts), the terms of this Section 10.4.6 shall apply.

(a)

In such event, the Parties wish to provide a mechanism to ensure that patients who were being treated with a Product prior to such termination or who desire access to a Product can continue to have access to such Product while the regulatory and commercial responsibilities for such Product are transitioned from Biogen to Ionis. As such, Ionis may request Biogen perform transition services as listed on Schedule 10.4.6 and such other transition services that the Parties mutually agree in writing to (1) provide patients with continued access to the applicable Products, (2) transition the responsibilities under all Approvals and ongoing Clinical Studies for the applicable Product to Ionis or its designee, and (3) transition the then-current supply process and responsibilities for the Products to Ionis or its designee (collectively, the “Transition Services”). Subject to the Parties agreeing on a transition plan as described in Section 10.4.6(b), Biogen will perform such Transition Services using reasonable efforts for a period not to exceed [***] months from the termination date; provided that Biogen and Ionis may mutually agree to conduct the Transition Services for a longer period of time. Notwithstanding the provision of the Transition Services under this Section 10.4.6(a), Ionis shall not conduct activities with respect to any Discontinued Products to the extent prohibited by ARTICLE 2 of this Agreement.

(b)

Ionis may elect to have Biogen perform the Transition Services by providing written notice to Biogen no later than 30 days following the effective date of the termination. If Ionis requests Transition Services, then Ionis shall propose a transition plan setting forth the Transition Services to be performed by Biogen, including delivery and transition dates consistent with those set forth on Schedule 10.4.6, and, for a period of 30 days after such request, the Parties will use good faith efforts to negotiate a mutually agreeable version of such transition plan. In addition, the Parties will, within 30 days after such request, establish a transition committee consisting of at least each Party’s Alliance Managers, a representative from each Party’s chemistry, manufacturing and controls (CMC) group who was responsible for the Products prior to the termination, and up to two additional representatives from each Party who are from other relevant functional groups to facilitate a smooth transition. While Biogen is providing Transition Services, Biogen and Ionis will mutually agree on talking points and a communication plan to customers, specialty pharmacies, physicians, Regulatory Authorities, patient advocacy groups, and clinical study investigators, and Biogen will make all such communication to such entities in accordance with the mutually agreed talking points.

Confidential

(c)

Ionis will pay Biogen for the Transition Services at [***]% of Biogen’s internal costs to perform the Transition Services, calculated using the same methodology as Biogen used to calculate such expenses for such Product in its most recently audited financial statements prior to the termination date. In addition, Ionis will reimburse [***]% of Biogen’s out-of-pocket costs to perform the Transition Services. Ionis will own all revenue derived from the Products after the termination date and Biogen will remit all such revenues to Ionis no later than the [***] day following the end of the month in which such revenue was received.

(d)

Ionis or its designee will be sufficiently prepared to accept the transition of Development, Manufacturing and Commercialization activities with respect to the Products to Ionis or such designee on the timelines set forth on Schedule 10.4.6 for the Transition Services. Biogen will have no liability under this Agreement with respect to a failure of or delay in the Transition Services to the extent caused by any failure or delay by Ionis or its designee in accepting the transition of Development, Manufacturing and Commercialization activities with respect to the Products. In the event that Biogen encounters any delays beyond Biogen’s reasonable control, the Parties shall discuss in good faith and agree upon extended timelines for completion of the Transition Services.
