ARTICLE 1.


RESEARCH AND DEVELOPMENT


 



	1.1.	
Collaboration Overview.







 



	 	1.1.1.	
The intent of the Collaboration is for the Parties to conduct (i) a neurological disease research program focused on the identification, validation, and applications of novel Neurology Targets, (ii) a broad core technology research program focused on enhancing the Parties’ knowledge of ASO pharmacokinetics and pharmacodynamics in the central and peripheral nervous systems, and (iii) an expanded drug discovery and development effort in Neurological Disease, including a program specifically focused on certain ALS Targets. This Agreement also provides Biogen the exclusive opportunity to select Collaboration Targets and Biogen Alternate Modality Targets from among all available Neurology Targets Ionis is independently researching up through Target Sanction.







 



		1.1.2.	
Once a Neurology Target reaches Target Sanction, the Neurology Target may be selected as a Collaboration Target, a Biogen Alternate Modality Target or both under this Agreement. Ionis will generate at least one Development Candidate, if feasible for each Collaboration Program that is not focused on an ALS Target or a Biogen Conducted Non-ALS Target; and advance each such Development Candidate through the completion of the first PoC Trial under the applicable Collaboration Program.







 



		1.1.3.	
When an ALS Target is selected as a Collaboration Target, Ionis will generate at least one Development Candidate, if feasible, for each ALS Collaboration Program; and Biogen will use Commercially Reasonable Efforts to advance each such Development Candidate through at least the completion of the first PoC Trial under the applicable Collaboration Program.







 



		1.1.4.	
Once a Biogen Conducted Non-ALS Target reaches Target Sanction, the Biogen Conducted Non-ALS Target may be selected as a Collaboration Target under this Agreement. Ionis will generate at least one Development Candidate, if feasible for each Biogen Conducted Non-ALS Collaboration Program; and Biogen will use Commercially Reasonable Efforts to advance each such Development Candidate through at least the completion of the first PoC Trial under the applicable Collaboration Program.

Confidential







		1.1.5.	
Ionis will provide Biogen an option to further Develop and ultimately Commercialize (I) Compounds and Collaboration Products under such Collaboration Programs, (II) Biogen Alternate Modality Products or (III) both Collaboration Products and Biogen Alternate Modality Products, in each case, under an exclusive license from Ionis.







 



		1.1.6.	
The Parties have agreed to form a collaboration steering committee to oversee the Collaboration under this Agreement, a joint research committee reporting to the CSC to oversee the Core Research Program, the Neurological Disease Research Program, and each ASO Development Candidate Identification Plan, and one or more joint development committees reporting to the CSC to oversee the development activities for Development Candidates.







 



		1.1.7.	
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, and therefore this Section 1.1 is qualified in its entirety by the more detailed provisions of this Agreement set forth below.







 



	1.2.	
Research Programs. Subject to and in accordance with the terms of this Agreement, during the Research Term, Ionis and Biogen will conduct two research programs, each under a separate mutually agreed plan. The first research program will cover research focused on enhancing the Parties’ knowledge of ASO pharmacokinetics and pharmacodynamics in the central and peripheral nervous systems (such program, the “Core Research Program” and the plan for such program, the “Core Research Plan”). The second research program will focus on the identification and validation of High Interest Targets, and the identification of ALS Targets, that are eligible to become Collaboration Targets (such program, the “Neurological Disease Research Program” and the plan for such program, the “Neurological Disease Research Plan”).  Drafts of the Core Research Plan and the initial Neurological Disease Research Plan have been mutually agreed upon by the Parties in writing on or prior to the Effective Date. The Parties will finalize these initially agreed draft plans within [***] days after the Effective Date. Thereafter, the Parties will update such plans at least once before the beginning of each Calendar Year, and submit them to the Neurology JRC for its review and approval.  Each update to the Neurological Disease Research Plan will include, at a minimum (i) the activities to support Target Sanction in the Calendar Year covered by such Neurological Disease Research Plan, (ii) any Neurological Disease research to support Collaboration Programs, and (iii) any ongoing work on High Interest Targets from prior Calendar Years.  Notwithstanding the foregoing, neither Party will be required to complete any activities under the Core Research Plan or Neurological Disease Research Plan if such Party in good faith believes that such activities are not technically feasible given the then-current state of the art.







 



		1.2.1.	
Research Term. The term for the conduct of the Core Research Program and the Neurological Disease Research Program will begin on the Effective Date and will end on the sixth anniversary of the Effective Date (the “Research Term”); provided, however, that (a) with respect to the Neurological Disease Research Program, (i) Ionis will not be required to begin target validation activities under the Neurological Disease Research Program (A) after the [***] anniversary of the Effective Date for any target that is not an ALS Target or (B) after the [***] anniversary of the Effective Date for any ALS Target, in each case, unless otherwise agreed to by the Parties and (ii) if any target validation activities that are Ionis Activities are ongoing under the Neurological Disease Research Plan on such sixth anniversary, Ionis will complete such activities in accordance with the Neurological Disease Research Plan, and the Research Term will be extended until the completion thereof and (b) with respect to the Core Research Program, Ionis will complete all Ionis Activities under the Core Research Plan that are ongoing on such sixth anniversary in accordance with such plan, and the Research Term will be extended until the completion thereof.

Confidential







		1.2.2.	
Core Research Program. The Core Research Program activities will focus primarily on investigating and optimizing delivery of ASOs to the CNS. Ionis will use Commercially Reasonable Efforts to conduct the Ionis Activities under the Core Research Program, and Biogen will use Commercially Reasonable Efforts to conduct the Biogen Activities under the Core Research Program. The Neurology JRC will update the Core Research Plan as needed during the Research Term.







 



		1.2.3.	
Neurological Disease Research Program. The Neurological Disease Research Program activities will focus primarily on identifying and validating novel Neurology Targets and prioritizing a list of High Interest Targets (defined below), including ALS Targets.







 



		(a)	
High Interest Targets. Under the Neurological Disease Research Plan, Biogen will establish a prioritized list of Neurology Targets, including ALS Targets to designate as high interest targets (each such target, a “High Interest Target” and such list the “High Interest Target List”).  The number of High Interest Targets cannot exceed [***].  The initial High Interest Target List has been mutually agreed upon by the Parties in writing on or prior to the Effective Date.  Biogen will present updates, if any, to the High Interest Target List at each meeting of the Neurology JRC.  Each Neurology Target added to the High Interest Target List will be a High Interest Target; provided, however, that if Ionis notifies Biogen within [***] days after the date on which Ionis receives a High Interest Target List containing a new High Interest Target that (1) [***], (2) such gene target is not eligible to become a High Interest Target hereunder [***], or (3) such gene target is [***], then the applicable gene target will not be a High Interest Target hereunder.  When Biogen adds a Neurology Target to the High Interest Target List, Biogen will identify on the High Interest Target List if Biogen intends such target to be an ALS Target.  Biogen may convert an ALS Target into a High Interest Target that is not an ALS Target at any meeting of the Neurology JRC. For clarity, Biogen may add any Ionis Neurology Target to the High Interest Target List so long as such Ionis Neurology Target is more than [***] months away from the date on which Ionis in good faith believes [***]. In addition, once target validating activities for a High Interest Target have been initiated under the Neurological Disease Research Plan or by Ionis independently (as presented by Ionis to the Neurology JRC), Biogen may not remove a High Interest Target from the High Interest Target List until [***]. The Parties acknowledge and agree that, as of August 4, 2014, [***] has been designated as a Collaboration Target that is an ALS Target under this Agreement. The Parties further acknowledge and agree that (a) notwithstanding any scientific determination regarding [***], the ALS Collaboration Program for [***] shall be treated as an ALS Collaboration Program that is not a [***] Collaboration Program for purposes of this Agreement, (b) [***] is not a Multi-Indication Target (as defined below) and (c) [***] is deemed to be a Pre-Existing Target (as defined below) for purposes of this Agreement.

Confidential







		(b)	
Multi-Indication Targets.  No later than [***] days following the addition of a particular High Interest Target to the High Interest Target List, Ionis may notify Biogen in writing that Ionis believes, in good faith, based upon published scientific literature or the results of Ionis’ internal research efforts, that such High Interest Target may have therapeutic benefit beyond Neurological Disease (each such High Interest Target, a “Multi-Indication Target”, and each such notice a “Multi-Indication Target Notice”). The Multi-Indication Target Notice will (i) include materials supporting Ionis’ belief that such High Interest Target may have therapeutic benefit beyond Neurological Disease and (ii) specify whether Ionis in good faith believes such Multi-Indication Target is a Primarily Neuro Multi-Indication Target, Equal Multi-Indication Target or Primarily Other Multi-Indication Target. If within [***] days of its receipt of a Multi-Indication Target Notice Biogen notifies Ionis in writing that Biogen wishes to remove the applicable Multi-Indication Target from the High Interest Target List, then such Multi-Indication Target will not be a High Interest Target but will continue to be a Neurology Target unless and until its status changes by operation of this Agreement. If Biogen does not so notify Ionis that it wishes to remove the applicable Multi-Indication Target from the High Interest Target List within such [***] day period, within [***] days after Biogen’s receipt of the applicable Multi-Indication Target Notice, Biogen will notify Ionis whether it agrees with Ionis’ determination as to whether the applicable Multi-Indication Target is a Primarily Neuro Multi-Indication Target, Equal Multi-Indication Target or Primarily Other Multi-Indication Target. If Biogen and Ionis agree with respect to such determination, then the agreed upon designation will be binding upon the Parties with respect to such Multi-Indication Target and the provisions of clauses (b)-(e) of Appendix 3 will apply with respect to such Multi-Indication Target. If Biogen does not agree with such determination, the Multi-Indication Target will be designated as a Primarily Neuro Multi-Indication Target, Equal Multi-Indication Target or Primarily Other Multi-Indication Target in accordance with Section 1.2.3(d) upon the Neurology JRC agreeing to conduct target validating activities for such Multi-Indication Target under the Neurological Disease Research Plan pursuant to Section 1.2.3(d) and prior to the commencement of such activities. For the avoidance of doubt, if Ionis fails to deliver a Multi-Indication Target Notice within [***] days after the addition of a particular High Interest Target to the High Interest Target List, such High Interest Target will not be a Multi-Indication Target hereunder.

		(c)	
Target Validation Under the Neurological Disease Research Program. The Neurology JRC will agree on an update to the Neurological Disease Research Plan annually. The first [***] years of the Research Term are planned to focus on validating the role of novel Neurology Targets that are not ALS Targets in Neurological Disease, with the goal of achieving Target Sanction for High Interest Targets, and providing for all pre-clinical development work under the Neurological Disease Research Plan required to validate such High Interest Targets.  Biogen will have final decision-making authority with respect to [***]. The Neurology JRC will determine the number of High Interest Targets for which activities to support Target Sanction will be conducted during each Calendar Year of the Research Term, which number will reflect the number of targets the Neurology JRC determines that Ionis can, in the exercise of Commercially Reasonable Efforts, (i) [***], (ii) [***], (iii) [***], and taking into account resources that may be used for ALS Targets, in each case using the number of FTEs provided for under Section 1.11.  Prior to the initiation of any activities to support Target Sanction with respect to any High Interest Target, Biogen will notify Ionis if such High Interest Target is a Neurology Target with respect to which Biogen has [***] intended for a neurology indication (a “Pre-Existing Target”).  Ionis will use Commercially Reasonable Efforts to conduct such activities to support Target Sanction on such High Interest Targets each year during the Research Term.  The Neurological Disease Research Plan will identify which Party will be responsible for the activities related to validation of such targets.  It is anticipated that Biogen will perform the [***] required under the Neurological Disease Research Plan where Biogen, at such time, already has in place at Biogen or through its collaborators the appropriate [***] and the ability to conduct such [***]; and that all other such [***] will be conducted by Ionis. Each Party will be responsible for the cost of the work it conducts under the Neurological Disease Research Program as more specifically detailed in Section 1.12 and Section 1.13.  Neither Party will be required to conduct work using [***] that are not similar in cost or technical feasibility to the [***] such Party has obtained from Third Parties and uses for its other programs.

Target Validation for Multi-Indication Targets. If the Neurology JRC agrees to conduct target validating activities under the Neurological Disease Research Plan with respect to any Multi-Indication Target that the Parties did not agree to designate as a Primarily Neuro Multi-Indication Target, Equal Multi-Indication Target or Primarily Other Multi-Indication Target pursuant to Section 1.2.3(b), within [***] days after such agreement, the CSC will meet to determine whether such target is a Primarily Neuro Multi-Indication Target, Equal Multi-Indication Target or Primarily Other Multi-Indication Target. If the CSC agrees on the appropriate classification for such Multi-Indication Target, the provisions of clauses (b)-(e) of Appendix 3 will apply with respect to such Multi-Indication Target. If the CSC cannot unanimously agree on the appropriate classification for a Multi-Indication Target at the applicable meeting, then such classification will be made pursuant to clause (a) of Appendix 3.

Neurology Targets that are not High Interest Targets. Subject to the provisions of Section 1.4 and Section 2.1.1(b) below, during the Research Term, either Party may work outside of the Collaboration on any Neurology Target that is not (i) a High Interest Target for which target validating activities are planned under the then-current Neurological Disease Research Plan, (ii) a Collaboration Target, or (iii) a Biogen Alternate Modality Target.







 



		1.2.4.	
Provision of ASOs for Research Outside of the Neurological Disease Research Program. During the Research Term, in accordance with and subject to the terms and conditions set forth on Schedule 1.2.4 (which represent the non-financial terms upon which Ionis generally provides its partners on a non-exclusive basis, research ASOs for independent research), Biogen may ask Ionis to use its ASO technology to provide research ASOs for up to [***] gene targets each successive [***] month period that are the focus of Biogen programs that are not part of the Collaboration.

Process for Designating High Interest Targets as Collaboration Targets or Biogen Alternate Modality Targets.   After the Parties complete the activities to achieve Target Sanction for a particular High Interest Target that is not an ALS Target, Ionis will deliver a Target Sanction Data Package for such High Interest Target to the Neurology JRC for review as soon as reasonably practicable.  Each time Ionis delivers the Neurology JRC a Target Sanction Data Package for a High Interest Target under this Section 1.3 the Parties will schedule a meeting of the Neurology JRC within [***] days following delivery of such Target Sanction Data Package. At such meetings the Neurology JRC will determine and record in the Neurology JRC minutes whether an ASO or Alternate Modality is the best therapeutic approach to pursue for such High Interest Target.  If the Neurology JRC cannot unanimously agree on which modality is the best therapeutic approach to pursue for a particular High Interest Target at such meeting, Biogen will have final decision making authority on the matter. Within the later of (x) [***] days following such meeting of the Neurology JRC or (y) [***] days after Biogen’s receipt of the Target Sanction Data Package for such High Interest Target, by written notice to Ionis, Biogen will either designate such High Interest Target as a Collaboration Target (in which case Section 1.6 will apply), a Biogen Alternate Modality Target (in which case Section 1.7 will apply), or a Deferred Target (in which case Section 1.8 will apply). If Biogen does not designate such High Interest Target as a Collaboration Target, a Biogen Alternate Modality Target, or Deferred Target within the timeframe set forth in the previous sentence, then (A) such High Interest Target (I) will not be designated a Collaboration Target or Biogen Alternate Modality Target and (II) will no longer be a Neurology Target under this Agreement and (B) the provisions of Section 2.1.1(f) will apply with respect to such target.  Notwithstanding the foregoing, if Ionis delivers the Neurology JRC a Target Sanction Data Package for a High Interest Target under this Section 1.3 and such High Interest Target is a Pre-Existing Target, then the Neurology JRC will not meet to discuss which modality is the best therapeutic approach for such High Interest Target, but Biogen will have [***] days after receipt of such Target Sanction Data Package to designate such High Interest Target as a Collaboration Target or a Deferred Target (treating, for purposes of Section 1.8, such target as a High Interest Target for which the best therapeutic modality was determined to be an ASO) by written notice to Ionis, but will not have the right to designate such High Interest Target as a Biogen Alternate Modality Target.  If Biogen does not designate such High Interest Target as a Collaboration Target or Deferred Target within the timeframe set forth in the previous sentence, then (X) such High Interest Target (I) will not be designated a Collaboration Target or a Deferred Target and (II) will no longer be a Neurology Target under this Agreement and (Y) the provisions of clause (x) (but not clause (y)) of Section 2.1.1(f) will apply with respect to such target.

Process for Designating Ionis Neurology Targets as Collaboration Targets.  If, during the Research Term in the course of conducting work outside of the Collaboration with respect to any Ionis Neurology Target, Ionis achieves Target Sanction with respect to such Ionis Neurology Target, then Ionis will deliver a Target Sanction Data Package for such Ionis Neurology Target to the Neurology JRC for review as soon as reasonably practicable. Within [***] days after the date Ionis delivered the applicable Target Sanction Data Package to the Neurology JRC, by written notice to Ionis, Biogen will either designate such Ionis Neurology Target as a Collaboration Target (in which case Section 1.6 will apply), or, to the extent permitted below, a Biogen Alternate Modality Target (in which case Section 1.7 will apply). If such Ionis Neurology Target was not a High Interest Target on the date of Target Sanction, Biogen will only have the right to designate such target as a Collaboration Target (and not, for the avoidance of doubt, as a Biogen Alternate Modality Target). If Biogen does not designate such Ionis Neurology Target as a Collaboration Target, or a Biogen Alternate Modality Target within [***] days after the date Ionis delivered the applicable Target Sanction Data Package to the Neurology JRC, such Ionis Neurology Target will no longer be a Neurology Target under this Agreement and Ionis and its Affiliates may work independently or with any Third Party with respect to the discovery, research, development, and commercialization of ASOs (or any other compounds) targeting such Ionis Neurology Target.

Process for Designating ALS Targets as Collaboration Targets. If Biogen desires Ionis to initiate ASO drug discovery activities on a particular ALS Target, then at the same time the Neurological Disease Research Plan for the Calendar Year in which Biogen desires Ionis to initiate such activities is updated to include activities for such Calendar Year, Biogen will designate such ALS Target as a Collaboration Target by providing written notice to Ionis; provided, if such ALS Target is a Multi-Indication Target, Biogen cannot designate such ALS Target as a Collaboration Target until such target has been classified by the CSC or by operation of Appendix 3 as a Primarily Neuro Multi-Indication Target, Equal Multi-Indication Target or Primarily Other Multi-Indication Target. In addition, Biogen cannot designate more than [***] ALS Targets as Collaboration Targets in any successive [***]-month period, and the total number of ALS Targets that are Collaboration Targets cannot exceed [***] without the Parties’ mutual agreement.

Designating a Deferred Target as a Collaboration Target or Biogen Alternate Modality Target; Credit for Deferral Fees. Biogen may designate a Deferred Target as a Collaboration Target or Biogen Alternate Modality Target, as applicable, by delivering written notice to Ionis of such designation (and if a Biogen Alternate Modality Target, the milestone payment under Section 6.2.2), before the expiration of the applicable Deferral Period under this Section 1.8; provided, however, that Biogen will not be permitted to designate such Deferred Target as a Biogen Alternate Modality Target if such Deferred Target is a Pre-Existing Target.  Biogen may credit [***]% of the total amount paid to Ionis under Section 1.8.2 for such Deferred Target against the milestone payment under Section 6.2.1 or Section 6.2.2, as applicable, for such Deferred Target. If Biogen does not designate a Deferred Target as a Collaboration Target or Biogen Alternate Modality Target in accordance with this Section 1.8.3 before the expiration of the applicable Deferral Period, then such gene target will no longer be a Neurology Target under this Agreement and any payments made by Biogen under this Section 1.8 for such Deferred Target will be non-creditable and non-refundable.

Ionis and its Affiliates may, for its own benefit and not for the benefit of any Third Party, conduct drug discovery activities to identify a Development Candidate for any Deferred Target for which the best therapeutic modality was determined to be an ASO (such Development Candidate, a “Deferred Target Development Candidate”); provided that Ionis may not use the FTEs provided for under Section 1.11 to conduct such activities. Ionis will notify the Neurology JRC of any such activities and keep the Neurology JRC reasonably apprised of the status thereof at each meeting of the Neurology JRC. If Ionis designates a Deferred Target Development Candidate targeting a particular Deferred Target (such target, an “Accelerated Target”), Ionis may notify Biogen in writing regarding Ionis’ designation of such Deferred Target Development Candidate and will provide Biogen the applicable Development Candidate Data Package. Within [***] days following Biogen’s receipt of the applicable Development Candidate Data Package, Biogen may designate the Accelerated Target as a Collaboration Target; provided however, that if Biogen designates such Accelerated Target as a Collaboration Target, in addition to any credits for annual deferral fees under Section 1.8.3, Biogen may credit a pro-rated portion of the un-credited [***]% of the last annual deferral fee paid to Ionis under Section 1.8.2 for such Deferred Target towards the applicable milestone payment under Section 6.2.1 (where such pro-ration will be based on the number of days between the payment of such deferral fee and the applicable designation of such Accelerated Target as a Collaboration Target, divided by the lesser of 365 days and the number of days between the payment of such deferral fee and the end of the Research Term).

Cost Estimates. After designation of a Development Candidate under a Collaboration Program that is not an ALS Collaboration Program or a Biogen Conducted Non-ALS Collaboration Program, the applicable Neurology JDC will agree on an initial estimate of the expected cost for Ionis to conduct the work [***] specified in the applicable Initial Development Plan, including Ionis’ expected [***] and [***] costs (each, a “Cost Estimate”). The initial Cost Estimate [***] shall be agreed on by the applicable Neurology JDC no later than [***] months prior to the anticipated [***]. Based on the Cost Estimates, the Neurology JDC will establish the [***] and [***] milestone payments for such Collaboration Program, which payments will be equal to (i) [***]; plus (ii) [***]. The Parties will promptly negotiate in good faith using the Ionis/Biogen Additional Agreements as a basis for Cost Estimates and, if the total milestone payment [***] is more than $[***], the Parties will apportion such total milestone payment into smaller milestone payments in accordance with Schedule 1.10.2(e); provided, however, that if [***], then the Neurology JDC shall determine whether and how to apportion such total milestone payment into smaller milestone payments. Each such smaller milestone payment shall be payable by Biogen within [***] days after receipt of the applicable invoice by Biogen following the event that triggered such milestone payment. If the total milestone payment [***] is $[***] or less, then such milestone payment shall become due in its entirety upon [***], and shall be payable by Biogen within [***] days after receipt of the applicable invoice by Biogen following [***]. As part of this process, Ionis will provide the Neurology JDC with a good faith estimate of the cost to conduct the work necessary to develop such Development Candidates under the applicable Initial Development Plan using a similar methodology as used under the Ionis/Biogen Additional Agreements. [***] months prior to the [***], using the process set forth above, the Neurology JDC will re-assess the total cost of such [***] and, if the cost has changed from the initial Cost Estimate, the Neurology JDC will adjust the applicable milestone payment accordingly, with any such adjustment to be agreed in writing to no later than the date that is [***] months prior to the [***]. Once there is less than [***] months prior to the [***], or such [***], if there are any changes to such [***] in accordance with this Agreement that result in an increase to the cost of such [***], then (a) if such cost is increased by more than [***], such increased costs will constitute an additional milestone payment to be paid in accordance with the provisions of this Section 1.10.2(e), or (b) if such cost is increased by [***], such increase will not affect the milestone payments for such [***] established under this Section 1.10.2(e), but instead will be handled in accordance with Section 1.14.1.  For clarity, with respect to any increase in the cost of a [***] by more than [***]% under clause (a) of the preceding sentence, if such increased costs total $[***] or less and such [***], then such increased costs shall become due in their entirety immediately, and shall be payable by Biogen within [***] days after receipt of the applicable invoice by Biogen. If the Neurology JDC cannot agree on the Cost Estimates within [***] days of receiving the proposed Cost Estimate, the matter will be referred to the CSC for resolution. Once the Neurology JDC has agreed on a Cost Estimate and/or the [***] milestone payments for such Collaboration Program are established under this Section 1.10.2(e) or Section 1.14.1, such agreement will be documented in a written side letter, in the form and format attached hereto as Appendix 4, which shall be executed by both Parties.

On a Collaboration Product-by-Collaboration Product basis, the [***] milestone payment in Table 3 is creditable against the first Milestone Event payment for [***]. For example, if the [***] Milestone Event is achieved by a Collaboration Product in the United States, then the milestone payment for such Milestone Event is creditable against the first to occur of the (i) [***] (ii) [***] or (iii) [***] milestone payments for such Collaboration Product.













		6.8.2.	
On a Biogen Alternate Modality Target-by-Biogen Alternate Modality Target basis, each milestone payment set forth in Table X above will be paid only once upon the first achievement of the Milestone Event regardless of how many Biogen Alternate Modality Products related to such Biogen Alternate Modality Target achieve such Milestone Event.













		6.8.3.	
On a Collaboration Program-by-Collaboration Program basis, each milestone payment set forth in Table 1, Table 2 and Table 3 above will be paid only once upon the first achievement of the Milestone Event regardless of how many Collaboration Products under such Collaboration Program achieve such Milestone Event.













		6.8.4.	
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. Similarly, if a Party proceeds directly to [***] without achieving the [***] then upon achieving the [***] Milestone Event, both the [***] and [***] Milestone Event payments are due.

		6.16.1.	
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.













		6.16.2.	
Withholding Tax.













		(a)	
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.













		(b)	
With respect to any commercial supply agreement entered between the Parties for the commercial supply of API under this Agreement, such supply agreement will (i) provide that only Biogen will claim any tax benefit allowed under IRC Section 199 Income Attributable to Domestic Production Activities, and (ii) include compensation to Ionis reflecting the value of the reasonably anticipated tax benefit under IRC Section 199 Income Attributable to Domestic Production Activities forfeited by Ionis.  If the IRS determines that Biogen is not entitled to the tax benefits under Section 199, Ionis is not required to reimburse Biogen for this tax benefit unless Ionis receives a cash benefit on its federal tax return.   A cash benefit will include any utilization of net operating losses that were generated in a year in which Ionis claimed any IRC Sec 199 deduction.  The reimbursement to Biogen would be an amount equal to the Section 199 deduction times thirty-five percent, less any administrative costs to compute the tax benefit.  The reimbursement would be due to Biogen within 90 days after filing any original or amended federal tax return.  If the IRS determines that Ionis is not eligible for the tax benefit or determines the tax benefit should be a different amount, Biogen will pay back to Ionis the amount of any adjustment.  Ionis will notify Biogen within 30 days of filing a return that claims such deduction or utilizes a related net operating loss.

		6.16.3.	
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 6.16.












The provisions of this Section 6.16 are to be read in conjunction with the provisions of Section 12.4 below.








	6.17.	
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.

		(b)	
Ionis or Biogen (as applicable) will provide the Joint Patent Committee 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 Neurology Plans or solely by a Third Party performing activities under the Neurology Plans 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 by Ionis 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, if such Party is unable to obtain [***] license to such Collaborator IP or if the Parties mutually agree that it is not necessary to obtain [***] license, such Party shall use Commercially Reasonable Efforts to obtain a [***] license to such Collaborator IP from such Third Party (any such [***] with such Third Party, a “Collaborator License”), and in each case such Party will endeavor to obtain in such Collaborator License the right to sublicense such Collaborator IP to the other Party on terms that contain no greater restrictions on the other Party’s use of such Collaborator IP than those set forth in this Agreement.












Notwithstanding any provision to the contrary in this Agreement, except for [***] obligation to pay any costs arising under any Third Party agreement as a result of granting Biogen the license under Section 4.4.1(b), if Collaborator IP (other than Additional Core IP) arises from activities performed by a Third Party under the applicable Neurology Plan, then any payment obligations arising under the applicable Collaborator License based on the Development or Commercialization of a Product will be paid as follows: (A) in the case where [***] enters into such Collaborator License, [***] will be solely responsible for paying any payment obligations that [***], and [***] will be solely responsible for paying any payment obligations that [***], and (B) in the case where [***] enters into such Collaborator License, [***] will be [***] responsible for paying any payment obligations that [***].

With respect to any such Collaborator IP licensed by Ionis under a Collaborator License with such Third Party, 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 Joint Patent Committee 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 by Ionis 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 Joint Patent Committee 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 Joint Patent Committee (or otherwise between Ionis and Biogen) over inventorship of Program Patents, if the Joint Patent Committee cannot resolve such dispute, even after seeking the CSC’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, 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 Joint Patent Committee 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 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.

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.

Prior to License Grant. 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(a) or Section 4.1.1(b) (as applicable), 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, however, Ionis will have the sole right to control such litigation. 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.

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 6.17 (Interest on Late Payments), 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.

Transition Services.













		(a)	
In the case where (i) Biogen terminates the Agreement under Section 10.2.1 (Biogen’s Termination for Convenience) or (ii) Ionis terminates this Agreement under Section 10.2.4(b) (Ionis’ Right to Terminate) or Section 10.2.5 (Remedies for Failure to Use Commercially Reasonable Efforts) with respect to one or more Products, the Parties wish to provide a mechanism to ensure that patients who were being treated with the Product prior to such termination or who desire access to the Product can continue to have access to such Product while the regulatory and commercial responsibilities for the 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 Product 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.













		(b)	
Ionis may elect to have Biogen perform the Transition Services by providing written notice to Biogen no later than [***] 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 [***] 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 [***] 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 Product 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.













		(c)	
Ionis will pay Biogen for the Transition Services at [***] to perform the Transition Services, calculated [***]. In addition, Ionis will reimburse [***] to perform the Transition Services. Ionis will own all revenue derived from the Product 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.

Multi-Indication Target Process







Neurology Targets with Broader Therapeutic Benefit.








		(a)	
If, pursuant to Section 1.2.3(d), the CSC is unable to agree upon whether a Multi-Indication Target is a Primarily Neuro Multi-Indication Target, Equal Multi-Indication Target or Primarily Other Multi-Indication Target, the Parties will engage an expert panel under Section 12.1.4 to make such determination. Such expert panel will first determine the net present value (“NPV”) of a therapeutic targeting such Multi-Indication Target and allocate such NPV between the markets for Neurological Disease indications and for Non-Neurological Indications, where such NPV calculations and allocations will take into consideration, and risk-adjust for, the relevant market sizes, competitive landscapes, scientific rationale for each market and any other factors deemed relevant by such expert panel.  Based on such NPV calculations and allocations, Multi-Indication Targets will be classified as either “Primarily Neuro Multi-Indication Targets”; “Equal Multi-Indication Targets” or “Primarily Other Multi-Indication Targets”, where (1) a Multi-Indication Target with [***]% or more of its NPV allocated to the market for Neurological Disease indications will be a Primarily Neuro Multi-Indication Target, (2) a Multi-Indication Target with less than [***]% but more than [***]% of its NPV allocated to the market for Neurological Disease indications will be an Equal Multi-Indication Target, and (3) a Multi-Indication Target with [***]% or less of its NPV allocated to the market for Neurological Disease indications will be Primarily Other Multi-Indication Target.













		(b)	
Primarily Neuro Multi-Indication Targets.  If a Multi-Indication Target is classified as a Primarily Neuro Multi-Indication Target, then within [***] days of such classification, Biogen will send Ionis a written notice either (1) electing to negotiate in good faith with Ionis a development plan and [***] (i.e., [***]) for the Non-Neurological Indications if Developed and Commercialized under this Agreement, which plan and provisions will be recommended to the CSC for approval; (2) granting Ionis and its Affiliates the right to work on their own or with a Third Party to discover, develop and commercialize an oligonucleotide against such Multi-Indication Target for primarily Non-Neurological Indications (an “Ionis Multi-Indication Compound”); or (3) precluding Ionis and its Affiliates from working on their own or with a Third Party to discover, develop commercialize an Ionis Multi-Indication Compound.  If under this clause (b) Ionis or any of its Affiliates or licensees Commercializes a product incorporating an Ionis Multi-Indication Compound, and Biogen has paid the applicable license fee under Section 6.6 for the applicable Collaboration Program, then until the earlier of (i) the [***] anniversary of the date of First Commercial Sale of such product or (ii) the date Biogen, its Affiliates and Sublicensees stop Commercializing the Product related to such Multi-Indication Target, Ionis will pay Biogen a royalty of [***]% of Annual worldwide Net Sales of such product sold by Ionis, its Affiliates or Sublicensees. The definition of Net Sales in Appendix 1 and the other provisions contained in Sections 6.14, 6.15, 6.16, and 6.17 governing payment of royalties from Biogen to Ionis will govern the payment of such royalty from Ionis to Biogen under this clause (b), mutatis mutandis.  If within [***] days of Biogen making an election under clause (1) of this clause (b) to pursue the Non-Neurological Indication, the CSC has not agreed on a development plan and enhanced economic provisions to be paid by Biogen for the Non-Neurological Indication, then (I) Ionis and its Affiliates will not work on their own or with a Third Party to discover, develop and commercialize in the Field an Ionis Multi-Indication Compound unless otherwise permitted under this Agreement and (II) Biogen and its Affiliates will not work on their own or with a Third Party to discover, develop or commercialize Compounds related to such Multi-Indication Target for Non-Neurological Indications.

		(c)	
Equal Multi-Indication Targets. If a Multi-Indication Target is classified as an Equal Multi-Indication Target, neither Party nor its respective Affiliates, licensees or Sublicensees may develop or commercialize a product targeting such Multi-Indication Target for any indication unless and until Ionis and Biogen have agreed on (i) a development plan and enhanced economic provisions to be paid by Biogen (i.e., multi-indication filing and approval milestone payments, but not additional license fees) for the Non-Neurological Indications, and (ii) the restrictions under which Ionis or Biogen (as applicable) would develop or commercialize a product targeting such Multi-Indication Target (which terms may include the requirements set forth under clause (d)(2) below).













		(d)	
Primarily Other Multi-Indication Targets.  If a Multi-Indication Target is classified as a Primarily Other Multi-Indication Target, then (A) Biogen may continue to Develop and Commercialize Products for Neurological Disease indications pursuant to the terms of this Agreement, and (B) within [***] days of such classification, Biogen will send Ionis a written notice either (1) electing to negotiate in good faith with Ionis and agree on a development plan and [***] (i.e., [***]) for the Non-Neurological Indications if Developed and Commercialized under this Agreement, which plan and provisions will be recommended to the CSC for approval; or (2) granting Ionis and its Affiliates the right to work on their own or with a Third Party to discover, develop and commercialize an Ionis Multi-Indication Compound so long as such Ionis Multi-Indication Compound [***], provided, in addition to the foregoing provisions, if the Development Candidate targeting such Multi-Indication Target being Developed or Commercialized by Biogen, its Affiliates or Sublicensees under this Agreement is [***], Ionis cannot develop or commercialize such Ionis Multi-Indication Compound for [***].

In addition, Biogen may not use Ionis data disclosed to Biogen in connection with this Schedule 1.2.4 or the Research ASOs to make products that incorporate oligonucleotides.







 



168











		b)	
Biogen hereby grants Ionis a non-exclusive, fully-paid sublicensable license under any Biogen Licensed Claims solely for the purpose of discovering, developing or commercializing an oligonucleotide(s) as a pharmaceutical product, provided, however, that such license will only be sublicensable by Ionis to a Third Party licensee in connection with the grant of an exclusive license to such Third Party under other Ionis intellectual property with respect to such oligonucleotide. No other license is granted to Ionis under any Biogen-owned or controlled Patent Right or other intellectual property under this Schedule 1.2.4.  For avoidance of doubt, no rights are granted by Biogen to Ionis under this Schedule 1.2.4 (expressly or by implication or otherwise) with respect to any compounds, materials or agents (or any method of use or manufacture thereof).













		c)	
Ionis hereby grants Biogen a non-exclusive, fully-paid sublicensable license under any Ionis Licensed Claims solely for the purpose of discovering, developing or commercializing a non-oligonucleotide compound(s) as a pharmaceutical product, provided, however, that such license will only be sublicensable by Biogen to a Third Party licensee in connection with the grant of an exclusive license to such Third Party under other Biogen intellectual property with respect to any such non‐oligonucleotide compound. “Ionis Licensed Claims” means the claims of any Ionis Invention that generically claims methods of treating disease by modulating an Accepted Gene Target, but are not directed to any specific compound or agent (including any oligonucleotide).  Except as set forth in Section 3.2(a) and (c), no other license is granted to Biogen under any Ionis-owned or controlled Patent Right or other intellectual property under this Schedule 1.2.4.












3.3. Non-exclusive Collaboration.








		a)	
Ionis will perform target validation activities and will provide Research ASOs to Biogen as set forth in the Target Validation Plan on a non-exclusive basis. Ionis may collaborate with Third Parties for target validation studies on any gene targets, including Accepted Gene Targets. In addition, this Schedule 1.2.4 will not limit Ionis from conducting research, discovery and development work on any and all oligonucleotides, for itself or with or on behalf of a Third Party.













		b)	
If an oligonucleotide to an Accepted Gene Target hereunder becomes a drug development candidate of Ionis or a Third Party collaborator of Ionis, Ionis will notify Biogen. Upon receipt of such notice from Ionis, Biogen will return to Ionis all unused quantities of applicable TV Compound within [***] days after the date on which Biogen received such notice.  After such time, Ionis will not have any obligation to provide additional quantities of the originally supplied TV Compound to Biogen under this Schedule 1.2.4.







 



169











		c)	
If Ionis achieves Target Sanction for an Accepted Gene Target, and Ionis does not at such time have any obligations to any Third Party with respect to such Accepted Gene Target that would conflict with Ionis’ compliance with this Section 3.3(c), Ionis will provide to Biogen a Target Sanction Data Package for such Accepted Gene Target (an “AGT Target Sanction Data Package”) and Biogen will have [***] days following receipt of such AGT Target Sanction Data Package to decide whether to negotiate with Ionis regarding an agreement with respect to such Accepted Gene Target (an “AGT Agreement”).  Following delivery of an AGT Target Sanction Data Package, Ionis will not initiate negotiations regarding or enter into an AGT Agreement with any Third Party until the earlier to occur of: (1) Biogen notifying Ionis that it declines the opportunity to negotiate with Ionis regarding such AGT Agreement; (2) Biogen not responding to Ionis within 30 days after receipt of such AGT Target Sanction Data Package; or (3) the AGT Negotiation Period expiring before Biogen and Ionis have entered into such AGT Agreement.  If Biogen or one of its Affiliates responds within [***] days after its receipt of the AGT Target Sanction Data Package indicating that Biogen or one of its Affiliates desires to negotiate with Ionis regarding the proposed AGT Agreement, Ionis and Biogen or one of its Affiliates will negotiate in good faith for 180 days thereafter (or such other period as mutually agreed by the Parties) (the “AGT Negotiation Period”) regarding a mutually satisfactory AGT Agreement. During the AGT Negotiation Period, Biogen or its Affiliate will make the first written proposal to Ionis setting forth all material business and legal terms on which Biogen or its Affiliate would be willing to enter into the proposed AGT Agreement with Ionis; provided that neither Party will have any obligation to enter into an AGT Agreement. If the AGT Negotiation Period expires before Biogen or its Affiliate and Ionis have entered into such AGT Agreement, Ionis will have no further obligation to negotiate with Biogen or its Affiliates with respect to such AGT Agreement and Ionis will be free to negotiate and enter an agreement with a Third Party with respect to an AGT Agreement [***]; provided, however, that Ionis will not enter into any such AGT Agreement with any Third Party unless the terms and pricing of such AGT Agreement, [***].







 


3.4. Biogen Materials.







Any materials provided by Biogen to Ionis in connection with a Biogen TV Target or Accepted Gene Target, including any biological materials with respect to screening assays, including any progeny, expression products, mutants, replicates, derivatives and modifications thereof, (such materials being individually and collectively referred to as the “Biogen Materials”) will be used by Ionis solely for purposes of performing activities in accordance with the  Target Validation Plan and any remaining Biogen Materials will be returned to Biogen (or destroyed as may be requested by Biogen in writing) promptly following the end of the applicable activities under the Target Validation Plan or earlier upon request by Biogen. All information related to such Biogen Materials will be Biogen Confidential Information. All such materials must be used with prudence and appropriate caution in any experimental work, since all of their characteristics may not be known.
