1.2.                   STAT3 Research and Development Responsibilities.

1.2.1.                  STAT3 Research and Development Plan Activities; Timelines. Isis will use Commercially Reasonable Efforts to conduct the Isis Conducted Activities designated under the STAT3 Research and Development Plan in accordance with the timelines specified therein, and AstraZeneca will use Commercially Reasonable Efforts to conduct the AstraZeneca Conducted Activities designated under the STAT3 Research and Development Plan in accordance with the timelines specified therein.

1.2.2.                  STAT3 Research and Development Plan. The Parties will continue to develop and refine the STAT3 Research and Development Plan initially agreed at the Effective Date as needed and update it at least once each six months, and submit it to the JSC for its review and comment. Subject to Section 4.1.4, any material changes to the STAT3 Research and Development Plan must be mutually agreed to by the Parties in accordance with the provisions of Section 4.1.3. On a rolling basis, the STAT3 Research and Development Plan will contain activities for at least the next [***], including the key Development and regulatory decisions for ISIS-STAT3Rx and the key factors that will be considered when making such Development and regulatory decisions.

1.2.3.                  Phase 1/2 Trial.

(a)                                 High Response Outcome Analysis. A “High Response Outcome” is achieved when the [***].

(b)                                 Medium Response Outcome Analysis. A “Medium Response Outcome” is achieved if, [***]. If there has not been a [***] in at least [***] of the evaluable DLBCL Patients in the Phase 1/2 Trial, then there has been a “Low Response Outcome.”

For purposes of this Agreement, “Durable Response” means [***].  DLBCL Patients who achieve a Durable Response at [***] of treatment with ISIS-STAT3Rx but who are discontinued from the Phase 1/2 Trial before 24 weeks of treatment due to electing to receive a bone marrow transplant (a “BMT Patient”) will be [***]; provided, however, that no more than [***] BMT Patients will be [***] for purposes of determining whether a High Response Outcome has been achieved and no more than [***] BMT Patient will be [***] for purposes of determining whether a Medium Response Outcome has been achieved.

(c)                                  Target Knock-Down. “Target Knock-Down” means [***]. The [***] sample must contain [***]. The [***] sample will be taken within [***]. Analysis can be based on results from [***].  The JSC will unanimously decide on [***].  The selected pathology laboratory that conducts Target Knockdown analysis will report the results of this analysis to the JSC which will review whether the Target Knockdown criteria have

3

been achieved.  The success criteria for Target Knock-Down requires [***]. The JSC will review the [***] on an ongoing basis with respect to quality of samples, post-treatment sampling time point, and technical challenges associated with measuring the [***]. If the JSC unanimously agree to a change in the Target Knock-Down criteria based on this ongoing data review, the criteria to meet the Target Knock-Down component of the response outcome will be amended. If there is a High Response Outcome and at least [***], then Target Knock-Down will [***].

(d)                     Safety Concern. For purposes of this Agreement, “Safety Concern” means [***].

(e)                      Notice of High Response Outcome, Medium Response Outcome or Low Response Outcome. Promptly following Isis’ determination that a High Response Outcome, Medium Response Outcome or Low Response Outcome has occurred, Isis will provide AstraZeneca with written notice (an “Outcome Notice”) of whether (i) there is a High Response Outcome (and whether at least [***]), Medium Response Outcome or Low Response Outcome, (ii) there is a Safety Concern, and (iii) Target Knock-Down was achieved, and will include with such Outcome Notice the available components of the Phase 1/2 Trial Data Package. AstraZeneca may dispute Isis’ determination regarding any of items (i), (ii) or (iii) described in this Section 1.2.3(e), by providing Isis written notice thereof within 30 days of AstraZeneca’s receipt of the Outcome Notice (in which case Section 1.2.4 will apply); otherwise the determinations set forth in the Outcome Notice will be binding on the Parties.

(f)                       AstraZeneca’s Response to the Phase 1/2 Trial Data Package.

(i)                                    If either (a) Target Knock-Down was not achieved and there was [***]; or (b) there is a Low Response Outcome; or (c) there is a Safety Concern (in each case whether determined under Section 1.2.3(e) or the Third Party expert under Section 1.2.4), then within 10 Business Days of the Outcome Notice or determination of the Third Party expert under Section 1.2.4 (as applicable) if AstraZeneca either (x) provides Isis with a written notice that it wishes to terminate the license granted by Isis to AstraZeneca under Section 6.1.1, or (y) does not provide any written notice as to whether or not it wishes to terminate the license or continue with the license, the license granted by Isis to AstraZeneca under Section 6.1.1 will terminate and no milestone payment for ISIS-STAT3Rx will be payable.

(ii)                                If either (a) AstraZeneca provides Isis with a written notice that it wishes to continue with the license under Section 6.1.1

4

despite its option to terminate its license to STAT3 Products under Section 1.2.3(f)(i) within the timeline specified therein, or (b) if such Section 1.2.3(f)(i) does not apply, then in the case of a High Response Outcome, Medium Response Outcome or Low Response Outcome (in each case whether determined under Section 1.2.3(e) or the Third Party expert under Section 1.2.4), the applicable milestone payment under TABLE 1 in Section 8.4 will become due following such determination, and AstraZeneca will pay Isis such milestone payment within 30 days after receipt of an invoice from Isis.  In addition, if there is a Medium Response Outcome, at the next meeting of the JSC, AstraZeneca will indicate whether it plans to [***].

(g)                                 AstraZeneca’s Continued Development Following Phase 1/2 Trial Data Package. Without limiting Section 1.2.1 or Section 7.1:

(i)                                    If the license granted by Isis to AstraZeneca under Section 6.1.1 is not terminated under Section 1.2.3(f)(i) and there is a High Response Outcome (or there is a Medium Response Outcome but AstraZeneca plans to [***]), then provided Isis has supplied the API to AstraZeneca in accordance with Section 4.6.1(b)(i), AstraZeneca will initiate a clinical study for ISIS-STAT3Rx in accordance with the STAT3 Research and Development Plan within [***] after AstraZeneca’s receipt of such Phase 1/2 Trial Data Package; and

(ii)                                If the license granted by Isis to AstraZeneca under Section 6.1.1 is not terminated under Section 1.2.3(f)(i) and there is a Medium Response Outcome (and AstraZeneca does not plan to [***]), provided Isis has supplied the API to AstraZeneca in accordance with Section 4.6.1(b)(i), AstraZeneca will initiate a Clinical Study within [***] after AstraZeneca’s receipt of such Phase 1/2 Trial Data Package.

(h)                     Subsequent [***] Development within [***] after a Medium Response Outcome. If AstraZeneca pays Isis the milestone payment under Column 2 of TABLE 1 in Section 8.4 for a Medium Response Outcome, but initiates a Clinical Study to evaluate ISIS-STAT3Rx as a [***] in DLBCL Patients within [***] after AstraZeneca’s Initiation of a Clinical Study to evaluate ISIS-STAT3 Rx as a [***] in DLBCL Patients, then (A) within 30 days after AstraZeneca’s receipt of an invoice from Isis, AstraZeneca will pay Isis an amount equal to $[***] ([***]), and (B) so long as AstraZeneca is developing or commercializing ISIS-STAT3Rx as a [***] in DLBCL Patients (i) with respect to any unachieved milestone events, in lieu of paying Isis the milestone payments under Column 2 of TABLE 1 in Section 8.4, AstraZeneca will pay to Isis the milestone payments as set forth in

5

Column 1 of TABLE 1 in Section 8.4 when a milestone event listed in TABLE 1 is achieved by a STAT3 Product, and (ii) the High Response Outcome royalty rates set forth in Section 8.8 will apply to STAT3 Products.

(i)                        Subsequent [***] Development more than [***] after a Medium Response Outcome. If AstraZeneca pays Isis the milestone payment under Column 2 of TABLE 1 in Section 8.4 for a Medium Response Outcome but subsequently Initiates a Clinical Study to evaluate ISIS-STAT3Rx as a [***] in DLBCL Patients more than [***] after AstraZeneca’s Initiation of a Clinical Study to evaluate ISIS-STAT3Rx as a [***] in DLBCL Patients, then AstraZeneca will continue to pay Isis the milestone payments under Column 2 of TABLE 1 in Section 8.4, AstraZeneca will have no obligation to pay Isis such $[***] payment or the milestone payments as set forth in Column 1 of TABLE 1 in Section 8.4, and the High Response Outcome royalty rates set forth in Section 8.8 will not apply to STAT3 Products.

1.2.4.                  Disputes Regarding High Response Outcome, Medium Response Outcome, Low Response Outcome, Safety Concern or Target Knock-Down. If under Section 1.2.3(e) AstraZeneca timely disputes whether (i) a High Response Outcome, Medium Response Outcome or Low Response Outcome has been achieved (including whether the [***]), (ii) there is a Safety Concern, or (iii) Target Knock-Down was achieved, then the Parties will promptly (but no later than 15 days after the dispute arises) engage and refer such dispute to a mutually agreed upon single, independent Third Party oncologist with expertise in the area and appropriate professional credentials.  Within 30 days of receiving the Phase 1/2 Trial Data Package, to the extent disputed by the Parties, such Third Party expert will determine whether there is a High Response Outcome, Medium Response Outcome, or Low Response Outcome and whether there is a Safety Concern, and/or if there is Target Knock-Down. The determination of the Third Party expert engaged under the preceding sentence will be final and binding on the Parties. The costs of any Third Party expert engaged under this Section 1.2.4 will be paid by the Party against whose position the Third Party expert’s determination is made.

ARTICLE 2.

[***] RESEARCH AND DEVELOPMENT PROGRAM

2.1.                            [***] Program Overview. The intent of the [***] Program is (i) for Isis to discover a development candidate for [***] and complete IND-Enabling Toxicology Studies with such development candidate, and (ii) for AstraZeneca to perform, among other activities, in vitro and in vivo experiments to support the selection of the [***] Development Candidate, and all other preclinical, clinical, regulatory and commercial activities related to [***] Products. The purpose of this Section 2.1 is to provide a high-level overview of the roles, responsibilities, rights and obligations of each Party under this Agreement with regard to the [***] Research and Development Plan, and therefore

6

this Section 2.1 is qualified in its entirety by the more detailed provisions of this Agreement set forth below.

2.2.                            [***] Research and Development Responsibilities.

2.2.1.                  [***] Research and Development Plan Activities; Timelines. Isis will use Commercially Reasonable Efforts to conduct the Isis Conducted Activities designated under the [***] Research and Development Plan (which is attached hereto as APPENDIX 2) in accordance with the timelines specified therein, and AstraZeneca will use Commercially Reasonable Efforts to conduct the AstraZeneca Conducted Activities designated under the [***] Research and Development Plan in accordance with the timelines specified therein. In addition, with respect to the [***] Program:

(a)                                 Isis will use Commercially Reasonable Efforts to designate an [***] Lead Candidate by [***]; and

(b)                                 subject to Section 2.2.3 and Section 2.2.4, Isis will initiate IND-Enabling Toxicology Studies no later than [***] after AstraZeneca notifies Isis of the Selection of the [***] Development Candidate under Section 2.2.3.

2.2.2.                  [***] Research and Development Plan. The Parties will continue to develop and refine the [***] Research and Development Plan initially agreed at the Effective Date as needed, and update it at least once each six months, and submit it to the JSC for its review and comment. Subject to Section 4.1.4, any material changes to the [***] Research and Development Plan must be mutually agreed to by the Parties in accordance with the provisions of Section 4.1.3. On a rolling basis, the [***] Research and Development Plan will contain activities for at least the next [***], including the key Development and regulatory decisions for the [***] Development Candidate and the key factors that will be considered when making such Development and regulatory decisions. In addition, once the [***] Development Candidate is selected under Section 2.2.3, the JSC will work to establish a plan for IND filing support and activities, which plan will include a timeline and responsibilities for filing the IND and will specify that AstraZeneca will [***]. To the extent that AstraZeneca has not fully used the [***] available to it pursuant to Section 6.5.1 or Section 7.1.5, then AstraZeneca shall be entitled to allocate such [***] to the activities to be performed by Isis pursuant to this Section 2.2.2.

2.2.3.                  [***] Development Candidate. Isis will use Commercially Reasonable Efforts to designate an [***] Lead Candidate by [***]. AstraZeneca shall be entitled to participate with Isis in the identification of an [***] Lead Candidate and a back-up and Isis will notify AstraZeneca in writing promptly after designating an [***] Lead Candidate and, together with such notice, Isis will provide AstraZeneca the applicable Lead Candidate Data Package. As promptly as possible (but no later than [***] after AstraZeneca receives such Lead Candidate Data Package) (such [***] deadline, which AstraZeneca has determined is sufficient for AstraZeneca to complete its candidate selection

7

identification criteria analysis, the “[***] Development Candidate Decision Deadline”), AstraZeneca will determine whether to select the [***] Lead Candidate (or another [***] Compound) as the [***] Development Candidate. In addition, during such [***] period, AstraZeneca will keep the JSC apprised of AstraZeneca’s progress in making a decision regarding which [***] Compound AstraZeneca may select as the [***] Development Candidate to enable Isis to plan as early as possible for manufacturing of the [***] Development Candidate for IND-Enabling Toxicology Studies. If the JSC determines that any back up [***] Compound(s) to the proposed [***] Lead Candidate should be considered alongside the proposed [***] Lead Candidate, then the JSC may unanimously agree to extend the [***] Development Candidate Decision Deadline if the JSC determines AstraZeneca should have additional time to consider both candidates before making a decision as to which may be selected as the [***] Development Candidate. If AstraZeneca selects the [***] Lead Candidate or any other [***] Compound as the [***] Development Candidate, then AstraZeneca will notify Isis of such selection by the [***] Development Candidate Decision Deadline, and will pay Isis the [***] Development Candidate milestone payment under Section 8.5 within 30 days after AstraZeneca’s receipt of an invoice from Isis. Subject to Section 2.2.4, if AstraZeneca either (i) provides a written notice that it has not selected the [***] Lead Candidate or any other [***] Compound as the [***] Development Candidate by the [***] Development Candidate Decision Deadline or (ii) does not provide Isis any written notice as to whether or not AstraZeneca has selected the [***] Lead Candidate or any other [***] Compound as the [***] Development Candidate by the [***] Development Candidate Decision Deadline, then the license granted by Isis to AstraZeneca under Section 6.1.2 will terminate and no milestone payment for such [***] Development Candidate will be payable.

2.2.4.                  Failure to Designate an [***] Lead Candidate or Select an [***] Development Candidate.

(a)                                 JSC Decides to Perform Additional Work. If AstraZeneca has not selected the [***] Lead Candidate or any other [***] Compound as the [***] Development Candidate by the [***] Development Candidate Decision Deadline but AstraZeneca informs Isis that it believes further work to pursue an [***] Development Candidate should be pursued, then, within 30 days after the [***] Development Candidate Decision Deadline, the JSC may unanimously decide to pursue further work to identify other [***] Compounds for consideration as the [***] Development Candidate under a mutually agreed amended [***] Research and Development Plan, in which case the license granted by Isis to AstraZeneca under Section 6.1.2  will not terminate as provided in Section 2.2.3.

(b)                                 Isis Fails to Designate an [***] Lead Candidate by [***]; the JSC Decides Not to Perform Additional Work. If (A) Isis, having used

8

Commercially Reasonable Efforts, does not designate an [***] Lead Candidate by [***], or (B) Isis has designated an [***] Lead Candidate by [***], but AstraZeneca has not selected the [***] Lead Candidate or any other [***] Compound as the [***] Development Candidate by the [***] Development Candidate Decision Deadline and the JSC has not unanimously decided to pursue further work to identify other [***] Compounds for consideration as the [***] Development Candidate under a mutually agreed amended [***] Research and Development Plan, then, if AstraZeneca elects to abandon its rights to [***] and terminate the license granted by Isis to AstraZeneca under Section 6.1.2, no [***] milestone payment will be payable but AstraZeneca may elect to add an additional Oncology Target to the Oncology Collaboration by providing Isis written notice of such election (together with the gene target AstraZeneca proposes to add to the Oncology Collaboration, including the gene name and the NCBI accession number or nucleic acid sequence for such gene target, and any Patent Rights comprised in AstraZeneca Background IP consistent with the process described in Section 3.3.5 below) on or before (X) [***], in the case of item (A) above, or (Y) within [***] after the last to occur in item (B) above, as applicable. If AstraZeneca timely provides Isis with such an election notice, and Isis and AstraZeneca mutually agree on the proposed target, then, upon Isis’ receipt of AstraZeneca’s written agreement to be responsible for any Target Encumbrances that Isis notifies AstraZeneca as being applicable to such proposed target and related Products, (i) such proposed target will be an Oncology Target and the Oncology Collaboration will be expanded to a total of four Oncology Targets, (ii) Isis’ obligations and AstraZeneca’s rights under this Agreement with respect to the [***] Research and Development Plan (including the [***] Development Candidate and all other [***] Compounds) will terminate, and (iii) the license granted by Isis to AstraZeneca under Section 6.1.2 will terminate and no [***] milestone payment will be payable.

2.2.5.                  Notice of Completion of IND-Enabling Toxicology Studies; IND Support Package. Isis will notify AstraZeneca in writing within 30 days after Isis achieves Completion of the IND-Enabling Toxicology Studies under the [***] Research and Development Plan and, together with such notice, will deliver to AstraZeneca the IND Support Package.

ARTICLE 3.

ONCOLOGY COLLABORATION; OPTIONS

3.1.                            Oncology Collaboration Overview. The intent of the Oncology Collaboration is (i) for Isis to generate an Oncology Lead Candidate for each of the Oncology Collaboration Programs, (ii) with respect to each such Oncology Lead Candidate, for AstraZeneca to perform certain in vitro and in vivo (animal) experiments to support their designation,

9

and (iii) for AstraZeneca to conduct IND-Enabling Toxicology Studies with the Oncology Development Candidate. For each Oncology Collaboration Program, AstraZeneca will have an exclusive option to further develop and commercialize Products under an exclusive license from Isis. The purpose of this Section 3.1 is to provide a high-level overview of the roles, responsibilities, rights and obligations of each Party under this Agreement with regard to the Oncology Collaboration Programs, and therefore this Section 3.1 is qualified in its entirety by the more detailed provisions of this Agreement set forth below. Both Parties agree that while the primary focus of the collaboration is oncology, if the JSC unanimously agrees, then targets outside oncology could be included in this Agreement either during the selection process described below or as Substituted Targets.

3.2.                            Oncology Research and Development Plan Activities and Term.

3.2.1.                  Oncology Research and Development Plan Activities; Timelines. Each Oncology Research and Development Plan will be mutually agreed to by the Parties, and subject to Section 4.1.4 any material changes to a Collaboration Plan will be mutually agreed to by the Parties in accordance with the provisions of Section 4.1.3. Isis will use Commercially Reasonable Efforts to conduct the Isis Conducted Activities designated under each Oncology Research and Development Plan in accordance with the timelines specified therein, and AstraZeneca will use Commercially Reasonable Efforts to conduct the AstraZeneca Conducted Activities designated under each Oncology Research and Development Plan in accordance with the timelines specified therein. In addition Isis will use Commercially Reasonable Efforts to designate an Oncology Lead Candidate with respect to a particular Oncology Target. Both Parties will use their Commercially Reasonable Efforts to agree to the Reserved Targets in accordance with the timelines in Section 3.3.5 and to designate the Oncology Targets in accordance with the timelines in Section 3.3.6.

3.2.2.                  Oncology Collaboration Term. The period during which the Parties will conduct the Oncology Collaboration (such period, the “Oncology Collaboration Term”) will begin on the Effective Date and will end on the [***] anniversary of the Effective Date; provided that if one or both Substitute Targets are substituted into the Oncology Collaboration in accordance with Section 3.3.7 below or an additional Oncology Target is added to the Oncology Collaboration in accordance with Section 2.2.4, then, in order to provide sufficient time to perform such additional activities with respect to such Substitute Target or additional Oncology Target, the Oncology Collaboration Term for all Oncology Collaboration Programs will be extended for an additional [***] from the date the last Substitute Target or additional Oncology Target was included in the Oncology Collaboration.

3.3.                            Oncology Collaboration.

3.3.1.                  Oncology Research and Development Plans. The Oncology Collaboration

10

will be carried out in accordance with a written research and development plan that sets forth all research and development activities of the Parties with respect to each Oncology Target through AstraZeneca’s Completion of the IND-Enabling Toxicology Studies (each such plan, an “Oncology Research and Development Plan”). Each time the Parties have designated one of the three Oncology Targets in accordance with Section 3.3.6, the JSC will unanimously agree on an Oncology Research and Development Plan for each such Oncology Target. Each Oncology Research and Development Plan will include a description of the specific activities to be performed by the Parties in support of the Oncology Collaboration Program, the specific criteria to achieve Target Sanction status for the Oncology Target, the specific activities to be performed to achieve an Oncology Development Candidate and projected timelines for completion of such activities. A template Oncology Research and Development Plan for guidance on the expected activities of each Party is attached hereto as APPENDIX 3, which will be used by the JSC as a starting point when creating each Oncology Research and Development Plan. The Parties will continue to develop and refine each Oncology Research and Development Plan initially agreed as needed, and update it at least once every six months, and submit it to the JSC for its review and comment.  AstraZeneca will ensure on a rolling basis that each Oncology Research and Development Plan contains activities for at least the next [***], including the key Development and regulatory decisions for the Oncology Development Candidate and the key factors that will be considered when making such Development and regulatory decisions, and will be consistent in scope with the STAT3 Research and Development Plan and [***] Research and Development Plan. For clarity, Isis will not be obligated to initiate work on more than [***] Oncology Targets (excluding a Substitute Target) in any rolling [***] period during the Oncology Collaboration Term to ensure even utilization of resources unless agreed otherwise unanimously by the JSC. Lastly, once an Oncology Development Candidate is selected under Section 3.3.3, the JSC will work to establish a plan for IND filing support and activities, which plan will include a timeline and responsibilities for filing the IND and will specify that AstraZeneca will reimburse Isis for its time incurred in performing Isis’ designated responsibilities in connection with the IND filing to the extent those responsibilities are not Isis Conducted Activities, at the FTE rate, and any of Isis’ reasonable travel expenses for travel requested by AstraZeneca, and its outside consultants’ costs and consultants’ reasonable travel expenses incurred by Isis in performing such activities agreed in advance by AstraZeneca. To the extent that AstraZeneca has not fully used the [***] available to it pursuant to Section 6.5.1 or Section 7.1.5, then AstraZeneca shall be entitled to allocate such [***] to the activities to be performed by Isis pursuant to this Section 3.3.1.

3.3.2.                  Target Sanction. The JSC will determine if an Oncology Target has achieved Target Sanction status based on the specific criteria determined by the JSC.  The JSC will record in the minutes of the JSC each time an Oncology Target

11

has achieved Target Sanction status.

3.3.3.                  Oncology Development Candidate Selection. Isis will notify AstraZeneca in writing promptly after designating an Oncology Lead Candidate and, together with such notice, Isis will provide AstraZeneca the applicable Lead Candidate Data Package. As promptly as possible (but no later than [***] after AstraZeneca receives such Lead Candidate Data Package) (each such [***] deadline, which AstraZeneca has determined is sufficient for AstraZeneca to complete its candidate selection identification criteria analysis, an “Oncology Development Candidate Decision Deadline”), AstraZeneca will determine whether to select the Oncology Lead Candidate (or another Oncology Compound) as an Oncology Development Candidate. In addition, during such [***] period, AstraZeneca will keep the JSC apprised of AstraZeneca’s progress in making a decision regarding which Oncology Compound AstraZeneca may select as the Oncology Development Candidate to enable Isis to plan as early as possible for manufacturing of the Oncology Development Candidate for IND-Enabling Toxicology Studies. If the JSC determines that any back up Oncology Compound to the proposed Oncology Lead Candidate should be considered alongside the proposed Oncology Lead Candidate, then the JSC may unanimously agree to extend the Oncology Development Candidate Decision Deadline if the JSC determines AstraZeneca should have additional time to consider both candidates before making a decision as to which may be selected as the Oncology Development Candidate. If AstraZeneca selects the Oncology Lead Candidate or any other Oncology Compound as an Oncology Development Candidate, then AstraZeneca will notify Isis of such selection by the Oncology Development Candidate Decision Deadline, and will pay Isis the Designation of Oncology Development Candidate milestone payment under Section 8.6 within 30 days after AstraZeneca’s receipt of an invoice from Isis. In addition, provided Isis has supplied the API to AstraZeneca in accordance with Section 4.6.1(b)(iii), AstraZeneca will initiate IND-Enabling Toxicology Studies under the applicable Oncology Research and Development Plan no later than [***] days after AstraZeneca pays Isis the Designation of Oncology Development Candidate milestone payment under Section 8.6.

If AstraZeneca either (i) does not provide Isis written notice that AstraZeneca has selected the Oncology Lead Candidate or any other Oncology Compound as the Oncology Development Candidate by the Oncology Development Candidate Decision Deadline, or (ii), provides Isis written notice that AstraZeneca has not selected the Oncology Lead Candidate or any other Oncology Compound as the Oncology Development Candidate by the Oncology Development Candidate Decision Deadline, then such Oncology Collaboration Program will no longer be a part of this Agreement and AstraZeneca’s Option for (and Isis’ obligations with respect to) such Oncology Collaboration Program will terminate and no milestone payments for such Oncology Collaboration Program will be payable.

12

3.3.4.                  Notice of Completion of IND-Enabling Studies; IND Support Package. AstraZeneca will notify Isis in writing within 30 days after each time Completion of the IND-Enabling Toxicology Studies is achieved under an applicable Oncology Research and Development Plan and, together with such notice, will deliver to Isis the applicable IND Support Package, always provided that the Parties may mutually agree that an IND-Enabling Toxicology Study should not be completed (for example if there is an unacceptable toxicity in the study).

3.3.5.                  Reserved Targets. The Parties will select certain gene targets to be reserved (each such reserved gene target, a “Reserved Target”) for potential selection as Oncology Targets under this Agreement according to the following schedule:

(a)                                 Within [***] after the Effective Date, Isis and AstraZeneca will mutually agree on a pool of [***] oncology gene targets to be reserved for selection of the first Oncology Target under this Agreement;

(b)                                 Within [***] after the Effective Date, Isis and AstraZeneca will mutually agree on a second pool of [***] oncology gene targets to be reserved for selection of the second Oncology Target under this Agreement; and

(c)                                  Within [***] after the Effective Date, Isis and AstraZeneca will mutually agree on a third pool of [***] oncology gene targets to be reserved for selection of the third Oncology Target under this Agreement.

As part of the process for determining which gene targets will be reserved as Reserved Targets for potential selection as Oncology Targets, during the relevant time periods described above during which the Parties will consider gene targets to be Reserved Targets, AstraZeneca will inform Isis (A) if any of AstraZeneca’s JSC or JPC members have knowledge (without conducting any additional investigation) of any additional Third Party licenses or other intellectual property rights that AstraZeneca requires in order for AstraZeneca to conduct its obligations under the Collaboration Plans if such Reserved Target was selected as an Oncology Target, and (B) if any Patent Rights comprised in AstraZeneca Background IP relate to any proposed gene targets, and whether AstraZeneca has the ability to grant a license or sublicense hereunder to such Patent Rights without violating the terms of any agreement with any Third Party. If AstraZeneca reports any of the conditions set forth in (A) or (B) of this Section 3.3.5(c) exist, then unless otherwise agreed by the Parties, such gene target will not be reserved as a Reserved Target for potential selection as an Oncology Target. Within [***] days after the Parties agree upon each pool of [***] Reserved Targets, Isis will inform AstraZeneca of any known encumbrances related to the Reserved Targets under any Third Party agreement to which Isis or its Affiliate is a party, including any payment obligations such as milestone and royalty payments (such encumbrances for which AstraZeneca is so notified, the “Target Encumbrances”). The JSC will maintain the list of Reserved Targets and will attach to the minutes of the JSC meeting any changes to such list of Reserved Targets.

13

3.3.6.                  Selection of the Three Oncology Targets. Within [***] after a designation of a pool of [***] Reserved Targets under Section 3.3.5, Isis and AstraZeneca will mutually agree on and designate one Reserved Target to be an Oncology Target that is the subject of an Oncology Collaboration Program. After selecting the Oncology Target, the remaining [***] unselected Reserved Targets will no longer be Reserved Targets, and Isis’ obligations and AstraZeneca’s rights under this Agreement with respect to such Reserved Targets (including but not limited to Section 5.1) will terminate. AstraZeneca will be responsible for any payment obligations arising from the Target Encumbrances identified in accordance with Section 2.2.4(b), Section 3.3.5 or Section 3.3.7 (other than Isis Supported Pass-Through Costs) applicable to such Oncology Targets and related Products. If Isis fails to notify AstraZeneca of a Target Encumbrance in accordance with Section 2.2.4(b), Section 3.3.5 or Section 3.3.7, such un-notified Target Encumbrance shall remain the responsibility of Isis. For clarity, this process will occur [***] times to nominate the [***] Oncology Targets and be complete no later than [***] from the Effective Date, and is illustrated in SCHEDULE 3.3.6, after which any remaining Reserved Targets will no longer be Reserved Targets.

3.3.7.                  Rights of Substitution.

(a)                                 Generally. At any time during the first [***] years of the Oncology Collaboration Term, AstraZeneca will have the right, subject to the limits set forth below, to propose that research and development activities be discontinued with respect to an Oncology Target for which [***] (a “Discontinued Target”), and to propose that a new oncology target be substituted for such Discontinued Target in accordance with the procedures set out below in Section 3.3.7(b) (such notice, a “Substitute Notice” and such newly proposed oncology target, a “Proposed Substitute Target”).

(b)                                 Proposing the Substitute Target. Within 30 days after Isis’ receipt of a Substitute Notice, Isis and AstraZeneca will discuss and mutually agree whether such Proposed Substitute Target will become an Oncology Target. Isis will, within [***] days after Isis’ receipt of any Substitute Notice, inform AstraZeneca of any Target Encumbrances applicable to the Proposed Substitute Target. If Isis and AstraZeneca mutually agree that the Proposed Substitute Target will become an Oncology Target, then such Proposed Substitute Target (a “Substitute Target”) will become an Oncology Target upon (i) Isis’ receipt of AstraZeneca’s written agreement to be responsible for any payment obligations arising from the Target Encumbrances identified in accordance with this Section 3.3.7(b) (other than Isis Supported Pass-Through Costs) applicable to such Substitute Target and related Products, and (ii) if the Substitute Target is substituted in as an Oncology Target after the Discontinued Target achieved Target Sanction status, Isis’ receipt of the payment in accordance with Section

14

3.3.7(d) below. For clarity, any Discontinued Target will no longer be an Oncology Target and will therefore no longer be a part of the Oncology Collaboration under this Agreement, and Isis’ obligations and AstraZeneca’s rights under this Agreement with respect to such Discontinued Target (including but not limited to Section 5.1.1) will terminate.

(c)                                  Number of Substitute Targets. Notwithstanding anything to the contrary contained in this Agreement, in no event will AstraZeneca have the right to designate more than [***] Substitute Targets under this Section 3.3.7; provided that no more than [***] of such [***] Substitute Targets can be substituted in for an Oncology Target that has reached [***] status.

(d)                                 Payment for the Substitute Target. If a Substitute Target is substituted in as an Oncology Target after [***] status for a Discontinued Target under this Section 3.3.7, AstraZeneca will pay Isis $[***] within 30 days after such Substitute Target is substituted in as an Oncology Target.

3.3.8.                  Oncology Research and Development Plans. If a Substitute Target is substituted in under Section 3.3.7, within 30 days after such substitution the Parties will mutually agree on an Oncology Research and Development Plan for such new Oncology Target using the template Oncology Research and Development Plan attached hereto as APPENDIX 3 as a starting point, subject to review and comment by the JSC, and remove any Oncology Research and Development Plan with respect to the Discontinued Target.

3.4.                            Expiration of Oncology Collaboration Term. On an Oncology Collaboration Program-by-Oncology Collaboration Program basis, if, despite the Parties’ Commercially Reasonable Efforts, by the expiration of the Oncology Collaboration Term, Isis has not designated an Oncology Lead Candidate with respect to a particular Oncology Target, then (i) the Parties’ will no longer have an obligation to perform any activities under this ARTICLE 3 with respect to such Oncology Collaboration Program; (ii) any Oncology Collaboration Program that has not reached the Development Candidate stage will no longer be considered an Oncology Collaboration Program and the applicable gene target associated therewith will no longer be an Oncology Target under this Agreement; (iii) the Parties’ respective obligations and AstraZeneca’s rights under this Agreement with respect to such Oncology Target and any Compounds targeting such Oncology Target will then terminate, and Isis will be free to Develop and Commercialize on its own or with a Third Party such Oncology Target and any ASOs targeting such Oncology Target; (iv) Isis will have exclusive rights (and AstraZeneca will, and hereby does grant Isis an exclusive license) to all data, results and information generated under the Oncology Collaboration Program for such Oncology Target to research, develop, manufacture and commercialize ASOs targeting such Oncology Target and AstraZeneca will promptly transfer to Isis copies of all such data, results and information in AstraZeneca’s possession, provided that if within five years after the expiration of the Oncology Collaboration Term for such Oncology Target, Isis is not Developing ASOs for such Oncology Target, such rights and license shall become non-

15

exclusive and (v) AstraZeneca will and hereby does grant Isis an irrevocable, royalty free non exclusive license to any Know-How and/or Patent Rights generated by AstraZeneca under the Oncology Collaboration Program for such Oncology Target to research, develop, manufacture and commercialize ASOs targeting such Oncology Target.  With regard to the Jointly-Owned Collaboration Technology for such Oncology Collaboration Program, Isis will control the Jointly-Owned Patents that result, and AstraZeneca will assign ownership to Isis on condition that Isis grants AstraZeneca an irrevocable, royalty-free, non-exclusive license for any purpose. For clarity, except to the extent expressly set forth in the foregoing, the expiration of the Oncology Collaboration Term will not affect the Parties’ respective rights and obligations with respect to any Oncology Collaboration Program that has reached the Development Candidate stage by the end of the Oncology Collaboration Term and for which AstraZeneca has timely exercised its Option under Section 3.5.

3.5.                            Options. On an Oncology Target-by-Oncology Target basis, AstraZeneca has an exclusive option which it may exercise at any time on or before 5:00 p.m. (Pacific time) on the [***] day (each, an “Option Deadline”) following the earlier of (i) [***], or (ii) [***] (each, an “Option”) to obtain from Isis the license set forth in Section 6.1.3 below. AstraZeneca will notify Isis whether AstraZeneca is exercising its Option to license the applicable Oncology Target (and all Products included in the applicable Oncology Collaboration Program) by notifying Isis in writing on or before the applicable Option Deadline.

3.5.1.                  If AstraZeneca notifies Isis in writing by the Option Deadline that AstraZeneca is exercising the Option, AstraZeneca shall pay Isis the license fee set forth in Section 8.2 within 30 days after AstraZeneca’s receipt of an invoice from Isis for such license fee, and Isis will, and hereby does, grant to AstraZeneca the license set forth in Section 6.1.3 below.

3.5.2.                  If AstraZeneca either (i) notifies Isis in writing by the Option Deadline that AstraZeneca is not exercising the Option, or (ii) does not provide any written notice to Isis by the Option Deadline as to whether or not AstraZeneca is exercising the Option, then AstraZeneca’s Option will expire and no license fee is payable under Section 8.2 with respect to such Option. In such a case, AstraZeneca will have no further rights to (and Isis will have no further obligations with respect to) such Oncology Target (including all Compounds included in the applicable Oncology Collaboration Program) and the gene target to which such Compounds are directed will no longer be an Oncology Target. Following any expiration of an Option under this Section 3.5.2, subject to agreeing otherwise as provided in Section 3.3.4, AstraZeneca will [***] and, upon [***], will promptly transfer to Isis all data, results and information related to the testing and studies with respect to the applicable Oncology Target in the possession of AstraZeneca and its contractors.

24

develop an ASO designed to bind to the RNA that encodes such Gene Target that is not the Product being developed by AstraZeneca (an “Isis Follow-On Product”), and (ii) after [***] for a Product, commercialize an Isis Follow-On Product.

5.1.3.                  Limitations and Exceptions to Each Party’s [***] Rights.

(a)                                 Exception and Limitations. The Parties acknowledge and agree that, in addition to playing a role in cancer, the gene target, [***], is also known to potentially play a role outside of oncology (e.g., [***]), and therefore targeting [***] with an [***] ASO is a possible approach for the treatment of non-oncology diseases. In exchange for AstraZeneca’s agreement to not develop or commercialize an ASO targeting [***] for [***] and to not develop or commercialize an [***] for [***], Isis has agreed to [***] ASOs outside of [***] that [***].

Therefore, with respect to [***], the Parties memorialize the foregoing general principles by hereby agreeing to the following specific restrictions and limitations:

(i)                        AstraZeneca’s [***] Field.

(1)               [***]. AstraZeneca does not have the right under Section 6.1.2 (nor does AstraZeneca have a license under Section 6.1.2 of this Agreement) to research, develop, manufacture, have manufactured, register, market and/or commercialize any ASO that is designed to bind to the RNA that encodes [***], for the diagnosis, prevention and/or treatment of [***].

(2)               [***] and Other Indications. AstraZeneca has the right under Section 6.1.2 (and has a license under Section 6.1.2 of this Agreement) to research, develop, manufacture, have manufactured, register, market and/or commercialize, on its own or with a Third Party (including granting an option or a license to a Third Party to do so), any ASO that is designed to bind to the RNA that encodes [***] for the diagnosis, prevention and/or treatment of:

a.                                      [***]. Any [***] disease in humans or animals for any [***] indication using any [***] ([***]); and

b.                                      All Other Indications. Any indications other than [***] and [***], using any [***] other than [***],

25

(such field described in this Section 5.1.3(a)(i), the “AstraZeneca [***]-Field”).

(ii)       Isis’ [***] Field. Isis has the right (including to grant an option or a license to a Third Party) to research, develop, manufacture, have manufactured, register, market and commercialize, on its own or with a Third Party (including granting an option or a license to a Third Party to do so), any ASO that has all of the following attributes:

(1)               is for the diagnosis, prevention and/or treatment of any disease in humans or animals other than for [***];

(2)               [***];

(3)               [***]; and

(4)               [***] (each such [***] Compound, an “[***] Lead Compound”).

Each such [***] ASO Isis is permitted to exploit is an “Isis [***]-Field ASO,” and the field described in this Section 5.1.3(a)(ii) is the “Isis [***]-Field.”

(b)                                 Other Limitations and Exceptions to Isis’ Exclusivity Covenants. Notwithstanding anything to the contrary in this Agreement, Isis’ practice of the following will not violate Section 5.1.1 or Section 5.1.2:

(i)                                    Performance of the Isis Conducted Activities;

(ii)                                Any activities permitted under the Prior Agreements as such agreements are in effect on the Effective Date and have been disclosed to AstraZeneca (and not as such Prior Agreements may be amended after the Effective Date); and

(iii)                            The granting of, or performance of obligations under, Permitted Licenses.

(c)                                  Other Limitations and Exceptions to AstraZeneca’s Exclusivity Covenants. Notwithstanding anything to the contrary in this Agreement, AstraZeneca’s performance of the AstraZeneca Conducted Activities will not violate Section 5.1.1 or Section 5.1.2.

Nothing in this ARTICLE 5 will require AstraZeneca to make any explicit statements on the [***] Product label in order to comply with AstraZeneca’s obligations in Section 5.1.3(a)(i).

26

5.2.                   Effect of Exclusivity on Indications. The Compounds are designed to bind to the RNA that encodes the Gene Targets in the Field, which are known to play a role in cancer. Isis and AstraZeneca are subject to exclusivity obligations under Section 5.1.1 and Section 5.1.2; however, the Parties acknowledge and agree that each Party (on its own or with a Third Party) may continue to discover, research, develop, manufacture and commercialize products that are designed to bind to the RNA that encodes a gene that is not a Gene Target (except, with respect to [***], Isis may do so with Isis [***]-Field ASOs) for any indication, even if such products are designed to treat cancer.

7.2.1.                  Isis maintains an internal database that includes information regarding the tolerability of its drug compounds, individually and as a class, including information discovered during pre-clinical and clinical development (the “Isis Internal ASO Safety Database”). In an effort to maximize understanding of the safety profile and pharmacokinetics of Isis compounds, AstraZeneca will cooperate in connection with populating the Isis Internal ASO Safety Database. To the extent collected by AstraZeneca and in the form in which AstraZeneca uses/stores such information for its own purposes, AstraZeneca will provide

34

Isis with information concerning toxicology, pharmacokinetics, safety pharmacology study(ies), serious adverse events and other safety information related to Products licensed by AstraZeneca under this Agreement as soon as practicable following the date such information is available to AstraZeneca (but not later than 30 days after AstraZeneca’s receipt of such information). In connection with any reported serious adverse event, AstraZeneca will provide Isis all serious adverse event reports, including initial, interim, follow-up, amended, and final reports. In addition, with respect to Products, AstraZeneca will provide Isis with copies of Annual safety updates filed with each IND and the safety sections of any final Clinical Study reports within 30 days following the date such information is filed or is available to AstraZeneca, as applicable. Furthermore, AstraZeneca will promptly provide Isis with any supporting data and answer any follow-up questions reasonably requested by Isis. All such information disclosed by AstraZeneca to Isis will be AstraZeneca Confidential Information; provided, however, that so long as Isis does not disclose the identity of a Product or AstraZeneca’s identity, Isis may disclose any such AstraZeneca Confidential Information to (i) Isis’ other partners pursuant to Section 7.2.2 below if such information is regarding class generic properties of ASOs, or (ii) any Third Party. AstraZeneca will deliver all such information to Isis for the Isis Internal ASO Safety Database to Isis Pharmaceuticals, Inc., ▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: Chief Medical Officer (or to such other address/contact designated in writing by Isis). AstraZeneca will also cause its Affiliates and Sublicensees to comply with this Section 7.2.1.

7.2.2.                  From time to time, Isis utilizes the information in the Isis Internal ASO Safety Database to conduct analyses to keep Isis and its partners informed regarding class generic properties of ASOs, including with respect to safety. As such, if and when Isis identifies safety or other related issues that may be relevant to a Product (including any potential class-related toxicity), Isis will promptly inform AstraZeneca of such issues and provide the data supporting Isis’ conclusions.

7.3                   Pharmacovigilance; ISIS-STAT3 Rx Safety Reporting.

7.3.1                     The Parties acknowledge that until [***] Isis will remain the holder of the original IND for ISIS-STAT3Rx (although this does not preclude AstraZeneca opening its own US IND for ISIS-STAT3Rx during that period) and that because AstraZeneca will conduct a Clinical Study in [***] in accordance with the STAT3 Research and Development Plan during such period, it is important that Isis and AstraZeneca coordinate their respective ISIS-STAT3Rx clinical trial and pre-clinical activities, including the collection and reporting of adverse events involving ISIS-STAT3Rx. Within [***] days after the Effective Date, the Parties will develop and agree in writing on a Drug Safety Information Agreement that will include safety data delivery procedures governing the collection, investigation, reporting, and delivery of information from AstraZeneca to Isis

35

concerning any adverse experiences, and any product quality and product complaints involving adverse experiences related to ISIS-STAT3Rx, sufficient to enable Isis to comply with its legal and regulatory obligations and internal processes and consistent with the terms of this Agreement. Upon transfer of Isis’ ISIS-STAT3Rx IND to AstraZeneca and assumption by AstraZeneca of regulatory responsibilities under the IND, AstraZeneca will assume responsibility for the global safety database related to ISIS-STAT3Rx, and will be solely responsible for reporting to Regulatory Authorities in accordance with the Applicable Law for expeditable adverse events and for periodic safety reporting relating to the safety of ISIS-STAT3Rx and will furnish copies of such reports to Isis. The Drug Safety Information Agreement will be revised following the closure of Isis’ IND.

7.3.2                     Within [***] after the Effective Date with respect to the STAT3 Program, and prior to the [***] with respect to each of the other Collaboration Programs, the Parties shall enter into a mutually agreed pharmacovigilance agreement (the “Pharmacovigilance Agreement”). The Parties shall comply with the provisions of such agreement. If there is any inconsistency between this Agreement and the Pharmacovigilance Agreement as it relates to Product safety, the terms of the Pharmacovigilance Agreement will prevail to the extent of such inconsistency.

On an Option-by-Option basis, following AstraZeneca’s written notice to Isis stating that AstraZeneca is exercising such Option in accordance with this Agreement, AstraZeneca will pay Isis a license fee of $[***] within 30 days after AstraZeneca’s receipt from Isis of an invoice for such license fee (for a total of $[***] if AstraZeneca exercises all three of its Options hereunder or, a total of $[***] if a fourth Oncology Collaboration Program is added under Section 2.2.4 (for a total of four Options) and AstraZeneca exercises all four of its Options hereunder).

36

8.3.                   Remaining Payment for the Options to the Oncology Targets. In partial consideration for the Options granted by Isis to AstraZeneca under Section 3.5 for each Oncology Target, within [***] days following the Effective Date, AstraZeneca shall notify Isis whether it wishes to continue with the Oncology Collaboration, and if it does will pay Isis $6,000,000 within 30 days after AstraZeneca’s receipt from Isis of an invoice from Isis for such amount. For the avoidance of doubt, only one payment of $6,000,000 is payable under this Section 8.3. If AstraZeneca either (i) does not notify Isis in writing within [***] days following the Effective Date that it wishes to proceed with the Oncology Collaboration, or (ii) notifies Isis in writing that AstraZeneca is not proceeding, then all of the Options will expire and the remaining payment of $6,000,000 under this Section 8.3 shall not be payable.

8.4.                   Milestone Payments for Achievement of Milestone Events by a STAT3 Product. If there is a High Response Outcome in the Phase 1/2 Trial and the license granted by Isis to AstraZeneca under Section 6.1.1 is not terminated under Section 1.2.3(f)(i) above, then, in accordance with Section 8.7.5, AstraZeneca will pay to Isis the milestone payments as set forth in Column 1 of TABLE 1 below when a milestone event listed in TABLE 1 is first achieved by a STAT3 Product. If there is a Medium Response Outcome (or a Low Response Outcome) in the Phase 1/2 Trial and the license granted by Isis to AstraZeneca under Section 6.1.1 is not terminated under Section 1.2.3(f)(i) above, then, in accordance with Section 8.7.5 and subject to the terms of Section 1.2.3(h), AstraZeneca will pay to Isis the milestone payments as set forth in Column 2 of TABLE 1 below when a milestone event listed in TABLE 1 is first achieved by a STAT3 Product:

TABLE 1

37

8.5.                   Milestone Payments for Achievement of Milestone Events by an [***] Product. In accordance with Section 8.7.5, AstraZeneca will pay to Isis the milestone payments as set forth in TABLE 2 below when a milestone event listed in TABLE 2 is first achieved by an [***] Product:

TABLE 2

8.6.                   Milestone Payments for Achievement of Milestone Events by an Oncology Product. On an Oncology Target-by-Oncology Target basis, in accordance with Section 8.7.5, AstraZeneca will pay to Isis the milestone payments as set forth in TABLE 3 below when

38

a milestone event listed in TABLE 3 is first achieved by an Oncology Product targeting such Oncology Target:

TABLE 3

8.7.                   Limitations on Milestone Payments; Exceptions; Notice.

8.7.1.                  Each milestone payment set forth in TABLE 1 and TABLE 2 above will be paid only once upon the first achievement of the milestone event regardless of how many Products achieve such milestone event.

8.7.2.                  Each milestone payment set forth in TABLE 3 above will be paid only once per each Oncology Target upon the first achievement of the milestone event regardless of how many Products for such Oncology Target achieve such milestone event.

8.7.3.                  If a particular milestone event is not achieved because Development or Commercial activities transpired such that achievement of such earlier milestone event was unnecessary or did not otherwise occur, then upon

39

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.

8.7.4.                  In addition, if a particular milestone event is achieved contemporaneously or in connection with another milestone event, then upon achievement of one such milestone event the other milestone event will also be deemed achieved and the milestone payments for both milestone events are due. For example, if AstraZeneca achieves the [***] milestone event and the [***] ([***]) that was the subject of such milestone event [***], then both the [***] and the [***] milestone event payments are due. Similarly, if AstraZeneca achieves the [***] milestone event and the [***] ([***]) that was the subject of such milestone event [***], then both the [***] and the [***] milestone event payments are due.

8.7.5.                  Each time a milestone event is achieved under this ARTICLE 8, AstraZeneca will send Isis, or Isis will send AstraZeneca, as the case may be, a written notice thereof promptly (but no later than five Business Days) following the date of achievement of such milestone event. Thereafter, Isis will promptly invoice AstraZeneca for the achievement of any milestone event under this ARTICLE 8 and such milestone payment will be due within 30 days after AstraZeneca’s receipt of such invoice.

8.8.                            Royalty Payments to Isis.

8.8.1.                  AstraZeneca Full Royalty. As partial consideration for the rights granted to AstraZeneca hereunder, subject to the provisions of this Section 8.8.1 and Section 8.8.2, AstraZeneca will pay to Isis royalties on Annual worldwide Net Sales of Products sold by AstraZeneca, its Affiliates or Sublicensees, on a country-by-country and Product-by-Product basis, in each case in the amounts as follows in TABLE 4 below (the “AstraZeneca Full Royalty”):

40

TABLE 4

41

Annual worldwide Net Sales will be calculated by taking the aggregate sum of Net Sales of Products for all countries worldwide.

(a)                                 AstraZeneca will pay Isis royalties on Net Sales of Products arising from named patient and other similar programs under Applicable Laws, and AstraZeneca will provide reports and payments to Isis consistent with Section 8.10. No royalties are due on Net Sales of Products arising from compassionate use and other programs providing for the delivery of Product at no cost. The sales of Products arising from named patient, compassionate use, or other similar programs will not be considered a First Commercial Sale for purposes of calculating the Royalty Period.

(b)                                 For purposes of clarification, any Isis Product-Specific Patents assigned to AstraZeneca as set forth in Section 6.3.1 will still be considered Isis Product-Specific Patents for determining the royalty term and applicable royalty rates under this ARTICLE 8.

8.8.2.                  Application of Royalty Rates. All royalties set forth under Section 8.8.1 are subject to the provisions of this Section 8.8.2, and are payable as follows:

(a)                     Royalty Period. AstraZeneca’s obligation to pay Isis the AstraZeneca Full Royalty above with respect to a Product will continue on a country-by-country and Product-by-Product basis from the date of First Commercial Sale of such Product until the later of the date of expiration of (i) the last Valid Claim within the Licensed Patents Covering such Product in the country in which such Product is made, used or sold, (ii) the data exclusivity period conferred by the applicable Regulatory Authority in such country with respect to such Product (e.g., such as in the case of an orphan drug), and (iii) the [***] ([***]) anniversary of the First Commercial Sale of such Product in such country (such royalty period, the “Royalty Period”).

(b)                    Limitation on Aggregate Reduction for AstraZeneca Royalties. In no event will the aggregate royalty offsets under Section 8.9.2(a)(i) and Section 8.9.4(b) reduce the royalties payable to Isis on Net Sales of a Product in any given period to an amount that is less than the greater of [***].

(c)                      End of Royalty Obligation. On a country-by-country and Product-by-Product basis, other than [***], AstraZeneca’s obligation to make royalty payments hereunder in such country will end on the expiration of the Royalty Period in such country.

42

8.9.                   Third Party Payment Obligations.

8.9.1.                  Existing In-License Agreements.

(a)                                 Isis’ Existing In-License Agreements. Certain of the Licensed Technology Controlled by Isis as of the Effective Date licensed to AstraZeneca under Section 6.1.1 and Section 6.1.2 or that may be licensed to AstraZeneca under Section 6.1.3, as the case may be, are in-licensed or were acquired by Isis under the agreements with Third Party licensors or sellers listed in APPENDIX 6 (such license or purchase agreements being the “Isis In-License Agreements”), and certain milestone or royalty payments and license maintenance fees may become payable by Isis to such Third Parties under the Isis In-License Agreements based on the Development or Commercialization of a Product by AstraZeneca, its Affiliate or Sublicensee under this Agreement. Any payment obligations arising under the Isis In-License Agreements:

(i)                                    as they apply to STAT3 Products or [***] Products, will be paid by [***] as [***], and

(ii)                                as they apply to Isis Product Specific Patents licensed in connection with the applicable Oncology Product after Option exercise, will be paid by [***] as [***], and

(iii)                            in connection with the applicable Oncology Product as they apply to Isis Core Technology Patents and Isis Manufacturing and Analytical Know-How and Isis Manufacturing and Analytical Patents will be paid by [***] as [***].

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

8.9.2.                  New In-Licensed Additional Product-Specific Patents.

(a)                                 Additional STAT3/[***] Product-Specific Patents.

(i)                        AstraZeneca or Isis, as the case may be, will promptly provide the other Party written notice of any additional Third Party Patent Rights necessary to practice an Isis Product-Specific Patent to Commercialize a STAT3 Product or [***] Product (“Additional STAT3/[***] Product-Specific Patents”) it believes it has identified and AstraZeneca will have the first right, but not the obligation, to negotiate with,

43

and obtain a license from the Third Party Controlling such Additional STAT3/[***] Product-Specific Patents. If AstraZeneca obtains any such Additional STAT3/[***] Product-Specific Patents then, subject to Section 8.8.2(b), AstraZeneca may offset an amount equal to [***]% of any [***] paid by AstraZeneca to such Third Party with respect to such Product against any [***]. [***].

(ii)                    If, however, AstraZeneca elects not to obtain such a license to such Additional STAT3/[***] Product-Specific Patents, AstraZeneca will so notify Isis, and Isis may obtain such a license to such Additional STAT3/[***] Product-Specific Patents and will include such Additional STAT3/[***] Product-Specific Patents in the license granted to AstraZeneca under Section 6.1.1 or Section 6.1.2 (as applicable) if AstraZeneca agrees in writing to pay Isis as AstraZeneca Supported Pass-Through Costs any and all costs arising under such Third Party agreement as they apply to STAT3 Products or [***] Products.

(b)                                 Additional Oncology Collaboration Product-Specific Patents.

(i)                        Prior to Option Exercise. If, after an Oncology Target is selected but prior to Option exercise for a particular Oncology Target, Isis obtains Third Party Patent Rights necessary to Commercialize an Oncology Product where such Patent Right would have satisfied the definition of an Isis Product-Specific Patent had Isis Controlled such Patent Rights on the Effective Date, then to the extent Controlled by Isis, Isis will include such Third Party Patent Rights in the license to be granted to AstraZeneca under Section 6.1.3 if AstraZeneca agrees in writing to pay Isis as AstraZeneca Supported Pass-Through Costs any and all costs arising under such Third Party agreement as they apply to such Oncology Products.

(ii)                    After Option Exercise.

(1)               On an Oncology Target-by-Oncology Target basis, after Option exercise, AstraZeneca or Isis, as the case may be, will promptly provide the other Party written notice of any additional Third Party Patent Rights necessary to practice an Isis Product-Specific Patent to Commercialize an Oncology Product (“Additional Oncology Product-Specific Patents”) it believes it has identified and AstraZeneca will have the first right, but not the obligation, to negotiate with, and obtain a license from the Third Party Controlling such

44

Additional Oncology Product-Specific Patents. If AstraZeneca obtains any such Additional Oncology Product-Specific Patents then any and all Third Party Obligations arising under such Third Party agreement will be paid by AstraZeneca as AstraZeneca Supported Pass-Through Costs.

(2)               If, however, AstraZeneca elects not to obtain such a license to such Additional Oncology Product-Specific Patents, AstraZeneca will so notify Isis, and Isis may obtain such a license to such Additional Oncology Product-Specific Patents and will include such Additional Oncology Product-Specific Patents in the license granted to AstraZeneca under Section 6.1.3 if AstraZeneca agrees in writing to pay Isis as AstraZeneca Supported Pass-Through Costs any and all costs arising under such Third Party agreement as they apply to such Oncology Products.

8.9.3.                  Additional Core IP In-License Agreements. Isis will negotiate with, and use Commercially Reasonable Efforts to obtain a license from, any Third Party controlling intellectual property that is necessary to practice an Isis Core Technology Patent to Commercialize a Product (“Additional Core IP”). For clarity, Additional Core IP does not include any Patent Rights claiming (or intellectual property related to) specific drug compositions, sequences, therapeutic methods, formulation or delivery technology, manufacturing or analytical methods, or other active ingredients. If Isis obtains such a Third Party license, Isis will include such Additional Core IP in the license granted to AstraZeneca under Section 6.1.1, Section 6.1.2 or Section 6.1.3 (as the case may be), and any financial obligations under such Third Party agreement will be paid solely by [***] as [***].

8.9.4.                  Disputes Regarding Additional STAT3/[***] Product-Specific Patents and Additional Core IP.

(a)                                 If Isis does not agree that certain intellectual property identified by AstraZeneca pursuant to Section 8.9.2(a) is an Additional STAT3/[***] Product-Specific Patent, or if AstraZeneca does not agree that a license is not necessary to practice an Isis Core Technology Patent to Commercialize a Product as provided in Section 8.9.3, Isis or AstraZeneca, as applicable will send written notice to such effect to the other Party, 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 an Additional STAT3/[***] Product-Specific Patent or whether a license is necessary to practice an Isis Core Technology Patent to Commercialize a Product. The determination of the Third Party expert engaged under the preceding sentence will be binding on the Parties solely for purposes of

45

determining whether [***]. The costs of any Third Party expert engaged under this Section 8.9.4 will be paid by the Party against whose position the Third Party lawyer’s determination is made.

(b)                                 Notwithstanding the determination of the Third Party lawyer under Section 8.9.4(a), if a Third Party Controlling an Additional STAT3/[***] Product-Specific Patent is awarded a judgment from a court of competent jurisdiction arising from its claim against AstraZeneca asserting that [***], AstraZeneca will be permitted to [***].

8.10.                     Payments.

8.10.1.           Commencement. Beginning with the Calendar Quarter in which the First Commercial Sale for a Product is made and for each Calendar Quarter thereafter, AstraZeneca will make royalty payments to Isis 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. If no royalties are payable in respect of a given Calendar Quarter, AstraZeneca will submit a written royalty report to Isis so indicating together with an explanation as to why no such royalties are payable. In addition, beginning with the Calendar Quarter in which the First Commercial Sale for a Product is made and for each Calendar Quarter thereafter, within [***] following the end of each such Calendar Quarter, AstraZeneca will provide Isis a preliminary, non-binding Product sales estimate for such Calendar Quarter.

8.10.2.           Mode of Payment. All payments under this Agreement will be (i) payable in full in U.S. dollars, regardless of the country(ies) in which sales are made, (ii) made by wire transfer of immediately available funds to an account designated by Isis in writing, and (iii) non-creditable (except as otherwise provided in Section 8.11),  and non-refundable. 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 AstraZeneca in accordance with the rates of exchange for the relevant month for converting such other currency into US Dollars used by AstraZeneca’s internal accounting systems, which are independently audited on an annual basis and which are in accordance with generally accepted accounting principles, fairly applied and as employed on a consistent basis throughout AstraZeneca’s operations.

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

46

8.11.            Audits. During the Agreement Term and for a period of [***] thereafter, at the request and expense of Isis, AstraZeneca will permit an independent certified public accountant of nationally recognized standing appointed by Isis and reasonably acceptable to AstraZeneca, 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 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 AstraZeneca, such auditor will sign a nondisclosure agreement reasonably acceptable to AstraZeneca in form and substance. Any and all records of AstraZeneca examined by such independent certified public accountant will be deemed AstraZeneca’s Confidential Information. Upon completion of the audit, the accounting firm will provide both AstraZeneca and Isis with a written report disclosing whether the royalty payments made by AstraZeneca 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 AstraZeneca, it is shown that AstraZeneca’s payments under this Agreement were more or less than the royalty amount which should have been paid, then the relevant Party will make all payments required to be made by paying the other Party the difference between such amounts to eliminate any discrepancy revealed by said inspection within 45 days of receiving the Audit Report, with interest calculated in accordance with Section 8.13; provided, however, that any such payment by Isis to AstraZeneca will be [***]. Isis will pay for such audit, except that if AstraZeneca is found to have underpaid Isis by more than [***] of the amount that should have been paid for the audited period, AstraZeneca will reimburse Isis the reasonable fees and expenses charged by the accounting firm for the audit.

8.12.                     Taxes.

8.12.1.                 Taxes On Income. Each Party alone will be solely responsible for paying any and all Taxes (other than withholding taxes required by Applicable Law to be paid by AstraZeneca or Isis (as the case may be) levied on account of, or measured in whole or in part by reference to, the income of such Party.

8.12.2.                 Indirect Taxes All payments are exclusive of Indirect Taxes. If any Indirect Taxes are chargeable in respect of any payments, the paying Party shall pay such Indirect Taxes at the applicable rate in respect of such payments following receipt, where applicable, of an Indirect Taxes invoice in the appropriate form issued by the receiving Party in respect of those payments.

The Parties shall issue invoices for all amounts payable under this Agreement consistent with Indirect Tax requirements and irrespective of whether the sums may be netted for settlement purposes. If such amounts of Indirect Taxes are refunded by the applicable Governmental Authority or other fiscal authority subsequent to payment, the Party receiving such refund will transfer such amount to the paying Party within forty-five (45) days of receipt. The Parties agree to reasonably cooperate to provide any information required by the Party pursuing a refund of Indirect Taxes paid.

47

8.12.3.                 Withholding Tax. To the extent the paying Party is required to deduct and withhold taxes on any payment, the paying Party will pay the amounts of such taxes to the proper governmental authority for the account of the receiving Party and remit the net amount to the receiving Party in a timely manner. The paying Party will promptly furnish the receiving Party with proof of payment of such taxes. If documentation is necessary in order to secure an exemption from, or a reduction in, any withholding taxes, the Parties will provide such documentation to the extent they are entitled to do so. In accordance with the procedures set forth in Section 11.3 and Section 11.4, (i) the receiving Party will also indemnify the paying Party for any tax, interest or penalties imposed on the paying Party if the paying Party improperly reduces or eliminates withholding tax based upon representations made by the receiving Party, and (ii) Isis will indemnify AstraZeneca for any withholding tax incurred on Isis Supported Pass-Through Costs that arises because these costs are deemed to not be beneficially owned by Isis.

8.12.4.                 Tax Cooperation. At least 15 days prior to the date a given payment is due under this Agreement, the non-paying Party will provide the paying Party with any and all tax forms that may be reasonably necessary in order for the paying Party to lawfully not withhold tax or to withhold tax at a reduced rate with respect to such payment under an applicable bilateral income tax treaty. Following the paying Party’s timely receipt of such tax forms from the non-paying Party, the paying Party will not withhold tax or will withhold tax at a reduced rate under an applicable bilateral income tax treaty, if appropriate under the Applicable Laws. The non-paying Party will provide any such tax forms to the paying Party upon request and in advance of the due date. Each Party will provide the other with reasonable assistance to enable the recovery, as permitted by Applicable Law, of withholding taxes resulting from payments made under this Agreement, such recovery to be for the benefit of the Party who would have been entitled to receive the money but for the application of withholding tax under this Section 8.12.

The provisions of this Section 8.12 are to be read in conjunction with the provisions of Section 14.3 below.

8.13.                        Interest. Any undisputed payments to be made hereunder that are not paid on or before the date such payments are due under this Agreement, and any payments that are pending resolution of any dispute (including under Section 1.2.4) unless the dispute is ruled in favour of the paying Party, 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.

48

ARTICLE 9.
INTELLECTUAL PROPERTY

9.1.                            Ownership.

9.1.1.                  Isis Technology and AstraZeneca Technology. As between the Parties, Isis will own and retain all of its rights, title and interest in and to the Licensed Know-How and Licensed Patents and AstraZeneca will own and retain all of its rights, title and interest in and to the AstraZeneca Know-How and AstraZeneca Patents, subject to any assignments, rights or licenses expressly granted by one Party to the other Party under this Agreement. For clarity, except as otherwise expressly provided in this Agreement, the scope of licenses granted by AstraZeneca under this Agreement shall not include AstraZeneca Background Intellectual Property.

9.1.2.                  Agreement Technology. Each Party will promptly disclose to the other Party in writing, and will cause its Affiliates to so disclose, the discovery, development, or creation of any invention made solely or jointly by the Parties in connection with the performance of obligations under this Agreement. Except as otherwise expressly permitted under this Agreement, neither Party or their Affiliates or respective Sublicensees shall license or exploit the Jointly-Owned Collaboration Technology outside the scope of this Agreement without the consent of the other Party, such consent not to be unreasonably withheld.

9.1.3.                  Joint Patent Committee.

(a)                     The Parties will establish a “Joint Patent Committee” or “JPC.”  The JPC will serve as the primary contact and forum for discussion between the Parties with respect to intellectual property matters arising under this Agreement, and will cooperate with respect to the activities set forth in this ARTICLE 9. A strategy will be discussed with regard to (x) prosecution and maintenance, defense and enforcement of Isis Product-Specific Patents, AstraZeneca Product-Specific Patents and Jointly-Owned Collaboration Patents that would be and/or are licensed to AstraZeneca under Section 6.1.1, Section 6.1.2 or Section 6.1.3, (y) defense against allegations of infringement of Third Party Patent Rights, and (z) 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 licenses granted hereunder. In addition, the JPC will ensure that all Patent Rights claiming (i) the specific composition of matter (the exact sequence and chemistry) of the [***] Development Candidate and the other [***] Lead Compounds and/or an Oncology Development Candidate, and/or (ii) methods of using such [***] Development Candidate and such [***] Lead Compounds and/or an Oncology Development Candidate as a prophylactic, therapeutic or diagnostic, will be separated into their own patent applications separate from other subject matter to ensure any such claims are licensed to AstraZeneca under Section 6.1.2 and assigned as Assignable [***] Product-Specific Patents and/or Isis Product Specific Patents under Section 6.3.1. Isis’ obligation to participate in the JPC will terminate on

49

the date Isis is no longer obligated to participate in the JSC. Thereafter, Isis will have the right and expects, but is not obligated, to participate in JPC meetings. In the case of existing Licensed Patents as of the Effective Date (e.g., STAT3) that are necessary or useful to exploit a STAT3 Compound/Product in the Field, the Parties are obligated to participate in JPC meetings to cooperate with respect to the activities set forth in this ARTICLE 9.

(b)                     In addition, the JPC will be responsible for the determination of inventorship. The determination of inventorship will be made in accordance with United States patent laws and therefore this will determine if the invention is solely or jointly owned by the relevant Party or Parties. The JPC will comprise an equal number of members from each Party, which may be one 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 9. 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 Senior Representatives for input and resolution pursuant to Section 14.1.1. 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.

9.2.                   Prosecution and Maintenance of Patents.

9.2.1.                  Patent Filings. The Party responsible for Prosecution and Maintenance of any Patent Rights as set forth in Section 9.2.2, Section 9.2.3 or Section 9.2.4 will endeavor to obtain patent protection for the 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.

9.2.2.                  Licensed Patents and AstraZeneca Patents.

(a)                     Isis Core Technology Patents and Isis Manufacturing and Analytical Patents. During the Agreement Term, Isis will control and be responsible for all aspects of the Isis Core Technology Patents, Isis Manufacturing and Analytical Patents and, subject to Section 9.2.4, Licensable [***] Product-Specific Patents.

50

(b)                     Isis Product-Specific Patents and Jointly-Owned Collaboration Patents. On a Gene Target-by-Gene Target basis, so long as the applicable license to AstraZeneca under Section 6.1.1, Section 6.1.2 or Section 6.1.3 (as applicable) is in effect, AstraZeneca will control and be responsible for all aspects of the Prosecution and Maintenance of:

(i)                                    With respect to STAT3 Products and Oncology Products licensed to AstraZeneca, the Isis Product-Specific Patents and Jointly-Owned Collaboration Patents; and

(ii)                                With respect to [***] Products, the Assignable [***] Product-Specific Patents,

In each case to the same extent Isis had the right to control and was responsible for such Prosecution and Maintenance immediately prior to such license, subject to Section 9.2.3 and Section 9.2.4, and AstraZeneca will grant Isis the license set forth in Section 6.3.2.

(c)                      AstraZeneca Patents. AstraZeneca will control and be responsible for all aspects of the Prosecution and Maintenance of all AstraZeneca Patents, subject to Section 9.2.3 and Section 9.2.5.

9.2.3.                  Jointly-Owned Collaboration Patents. Isis will control and be responsible for all aspects of the Prosecution and Maintenance of Jointly-Owned Collaboration Patents that (i) do not Cover Products, and (ii) have not been licensed to AstraZeneca under Section 6.1.1, Section 6.1.2 or Section 6.1.3 (as applicable) that Cover Products. AstraZeneca will control and be responsible for all aspects of the Prosecution and Maintenance of Jointly-Owned Collaboration Patents licensed to AstraZeneca under Section 6.1.1, Section 6.1.2 or Section 6.1.3 (as applicable) that Cover Products.

9.2.4.                  Prosecution of Licensable [***] Product-Specific Patents.

(a)                                 Prosecution Principles. Because the license granted by Isis to AstraZeneca under Section 6.1.2 is limited in scope to the AstraZeneca [***]-Field, Isis may have an additional licensee under the Licensable [***] Product-Specific Patents to exploit Isis [***]-Field ASOs in the Isis [***]-Field (an “Isis [***]-Field ASO Licensee”). The purpose of this provision is to ▇▇▇▇▇▇ the full and complete development, maintenance, and protection of the Licensable [***] Product-Specific Patents and to protect the rights of all interested parties, by outlining (i) the procedures for filing, prosecuting, and maintaining the Licensable [***] Product-Specific Patents, (ii) Isis’ commitment to fairly control filing, prosecution, and maintenance of the Licensable [***] Product-Specific Patents, and (iii) equitable cost-sharing allocations between AstraZeneca and the Isis [***]-Field ASO Licensee related thereto.

51

(b)                                 Procedures for Prosecution of Licensable [***] Product-Specific Patents. Isis will have the sole right and responsibility to obtain, prosecute, and maintain throughout the world (in such countries as are commercially appropriate) the Licensable [***] Product-Specific Patents using Commercially Reasonable Efforts with the objective of obtaining maximum claim coverage for all compounds and products (including [***] Compounds and [***] Products and their uses in the Field), with Patent Costs shared equally between the Isis [***]-Field ASO Licensee and AstraZeneca (collectively, the “Participating Parties”), or shared equally between AstraZeneca and Isis if no such Isis [***]-Field ASO Licensee exists. Isis, as controlling party (or its outside counsel), will provide the Participating Parties with an update of the filing, prosecution, and maintenance status for each of such Licensable [***] Product-Specific Patent on a periodic basis and will reasonably consult and cooperate with the Participating Parties with respect to the preparation, filing, prosecution, and maintenance of such Licensable [***] Product-Specific Patents, including providing the Participating Parties with drafts of proposed filings as soon as reasonably possible after such drafts are prepared and, in any case, in sufficient time to allow the Participating Parties to review and comment before such filings are due. Isis (or its outside counsel) will provide the Participating Parties with copies of any documents relating to the filing, prosecution, and maintenance of such Licensable [***] Product-Specific Patents promptly upon their being filed or received. For clarity, Isis may cease prosecuting or maintaining particular applications or patents in the Licensable [***] Product-Specific Patents in selected jurisdictions, if Isis determines that it is not commercially reasonable to continue such efforts; provided, however, that Isis will not discontinue such prosecution or maintenance with respect to a particular issued Licensable [***] Product-Specific Patent that Covers the [***] product, [***] Development Candidate or any other [***] Lead Compounds, or the use thereof and will not discontinue such prosecution or maintenance without first notifying AstraZeneca, and AstraZeneca will have the right, but not the obligation, to prosecute and maintain such Licensable [***] Product-Specific Patent in the applicable country at its own expense with counsel of its own choice by providing written notice to Isis within 30 days after AstraZeneca receives such discontinuance notice from Isis.

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

(a)                                 Each Party will keep the other Party informed through the Joint Patent Committee as to material developments with respect to the Prosecution and Maintenance of the Product-Specific Patents or Jointly-Owned Collaboration Patents for which such Party has responsibility for Prosecution and Maintenance pursuant to Section 9.2.2, Section 9.2.3, Section 9.2.4 or this Section 9.2.5, including by providing copies of material data as it arises, any office actions or office action responses or

52

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 AstraZeneca elects (i) not to file and prosecute patent applications for the Jointly-Owned Collaboration Patents or Isis Product-Specific Patents that have been licensed or assigned to AstraZeneca under this Agreement or the AstraZeneca Product-Specific Patents (“AstraZeneca-Prosecuted Patents”) in a particular country, (ii) not to continue the prosecution (including any interferences, oppositions, reissue proceedings, re-examinations, and patent term extensions, adjustments, and restorations) or maintenance of any AstraZeneca-Prosecuted Patent in a particular country, or (iii) not to file and prosecute patent applications for the AstraZeneca-Prosecuted Patent in a particular country following a written request from Isis to file and prosecute in such country, then AstraZeneca will so notify Isis promptly in writing of its intention (including a reasonably detailed rationale for doing so) in good time to enable Isis to meet any deadlines by which an action must be taken to establish or preserve any such Patent Right in such country; and Isis will have the right, but not the obligation, to file, prosecute, maintain, enforce, or otherwise pursue such AstraZeneca-Prosecuted Patent in the applicable country at its own expense with counsel of its own choice. In such case, AstraZeneca will cooperate with Isis to file for, or continue to Prosecute and Maintain or enforce, or otherwise pursue such AstraZeneca-Prosecuted Patent in such country in Isis’ own name, but only to the extent that AstraZeneca is not required to take any position with respect to such abandoned AstraZeneca-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 AstraZeneca under this Agreement. Notwithstanding anything to the contrary in this Agreement, if Isis assumes responsibility for the Prosecution and Maintenance of any such AstraZeneca-Prosecuted Patent under this Section 9.2.5(b), Isis will have no obligation to notify AstraZeneca if Isis intends to abandon such AstraZeneca-Prosecuted Patent.

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

53

(d)                     If the Party responsible for Prosecution and Maintenance pursuant to Section 9.2.3 intends to abandon such Jointly-Owned Collaboration Patent without first filing a continuation or substitution, then such Party will notify the other Party of such intention at least 60 days before such Jointly-Owned Collaboration Patent will become abandoned, and such other Party will have the right, but not the obligation, to assume responsibility for the Prosecution and Maintenance thereof at its own expense (subject to Section 9.3.1) with counsel of its own choice, in which case the abandoning Party will, and will cause its Affiliates to, assign to the other Party (or, if such assignment is not possible, grant a fully-paid exclusive license in) all of their rights, title and interest in and to such Jointly-Owned Collaboration Patents. If a Party assumes responsibility for the Prosecution and Maintenance of any such Jointly-Owned Collaboration Patents under this Section 9.2.5(d), such Party will have no obligation to notify the other Party of any intention of such Party to abandon such Jointly-Owned Collaboration Patents.

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

9.3.                            Patent Costs.

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

9.3.2.                  Licensed Patents and AstraZeneca Patents. Except as set forth in Section 9.2.4 and Section 9.3.1, each Party will be responsible for all Patent Costs incurred by such Party prior to and after the Effective Date in all countries in the Prosecution and Maintenance of Patent Rights for which such Party is responsible under Section 9.2.

9.4.                   Defense of Claims Brought by Third Parties.

9.4.1.                  Oncology Products — Prior to Option Exercise. If a Third Party initiates a Proceeding claiming a Patent Right owned by or licensed to such Third Party is

54

infringed by the Development, Manufacture or Commercialization of any Oncology Product being researched or developed under an Oncology Collaboration Program with respect to which AstraZeneca has not yet exercised its Option, Isis will have the first right, but not the obligation, to defend against any such Proceeding at its sole cost and expense. If Isis elects to defend against such Proceeding, then Isis will have the sole right to direct the defense and to elect whether to settle such claim; provided, however, Isis will not settle such Proceeding without the prior written consent of AstraZeneca (such consent not to be unreasonably withheld, conditioned or delayed). AstraZeneca will reasonably assist Isis in defending such Proceeding and cooperate in any such litigation at the request and expense of Isis. Isis will provide AstraZeneca with prompt written notice of the commencement of any such Proceeding that is of the type described in this Section 9.4, and Isis will keep AstraZeneca apprised of the progress of such Proceeding. If Isis elects not to defend against such a Proceeding, then Isis will so notify AstraZeneca in writing within 60 days after Isis first receives written notice of the initiation of such Proceeding, and AstraZeneca will have the right, but not the obligation, to defend against such Proceeding at its sole cost and expense and thereafter AstraZeneca will have the sole right to direct the defense thereof, including the right to settle such claim (but only with the prior written consent of Isis, which consent will not be unreasonably withheld, delayed or conditioned). 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 9.4. Each Party will provide the other Party with prompt written notice of the commencement of any such Proceeding under this Section 9.4, 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.

9.4.2.                  STAT3 Products, [***] Products and Oncology Products After Option Exercise. 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 any (i) STAT3 Product or [***] Product being developed or commercialized by AstraZeneca under a license granted under Section 6.1.1 or Section 6.1.2, or (ii) Oncology Product being developed or commercialized by AstraZeneca under a license granted under Section 6.1.3, then in any of those cases AstraZeneca will have the first right, but not the obligation, to defend against any such Proceeding at its sole cost and expense. If AstraZeneca elects to defend against such Proceeding, then AstraZeneca 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 Isis, not to be unreasonably withheld, conditioned or delayed). Isis will reasonably assist AstraZeneca in defending such Proceeding and cooperate in any such litigation at the request and expense of AstraZeneca. AstraZeneca will provide Isis with prompt written notice of the commencement of any such Proceeding that is of the type described in this Section 9.4, and AstraZeneca will keep Isis apprised of the progress of such Proceeding. If AstraZeneca elects not to defend against a

55

Proceeding, then AstraZeneca will so notify Isis in writing within 60 days after AstraZeneca first receives written notice of the initiation of such Proceeding, and Isis will have the right, but not the obligation, to defend against such a Proceeding at its sole cost and expense and thereafter Isis will have the sole right to direct the defense thereof, including the right to settle such claim (but only with the prior written consent of AstraZeneca, which consent will not be unreasonably withheld, delayed or conditioned). Notwithstanding the foregoing, if [***]; provided, however, [***]. 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 9.4. Each Party will provide the other Party with prompt written notice of the commencement of any such Proceeding under this Section 9.4, 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. Notwithstanding the foregoing, if a Proceeding described under this Section 9.4.2 involves one or more Licensable [***] Product-Specific Patents and there is an Isis [***]-Field ASO Licensee as contemplated under Section 9.2.4, then the defense against any such Proceeding will be conducted in the collective interest of, such Isis [***]-Field ASO Licensee and AstraZeneca, and this Section 9.4.2 will be read and construed in a manner that is consistent with the principles described in Section 9.2.4 except that AstraZeneca will retain sole control in respect of the defense strategy for the Assignable [***] Product-Specific Patents.

9.4.3.                  Discontinued Product. If a Third Party initiates a Proceeding claiming that any Patent Right or Know-How owned by or licensed to such Third Party is infringed by the Development, Manufacture or Commercialization of a Discontinued Product, Isis will have the first right, but not the obligation, to defend against and settle such Proceeding at its sole cost and expense. AstraZeneca will reasonably assist Isis in defending such Proceeding and cooperate in any such litigation at the request and expense of Isis. Each Party may at its own expense and with its own counsel join any defense directed by the other Party. Isis will provide AstraZeneca with prompt written notice of the commencement of any such Proceeding, or of any allegation of infringement of which Isis becomes aware and that is of the type described in this Section 9.4.3, and Isis will promptly furnish AstraZeneca with a copy of each communication relating to the alleged infringement received by Isis.

9.4.4.                  Interplay Between Enforcement of IP and Defense of Third Party Claims.   Notwithstanding the provisions of Section 9.4.1 and Section 9.4.3, to the extent that a Party’s defense against a Third Party claim of infringement under this Section 9.4 involves (i) the enforcement of the other Party’s Know-How or Patent Rights, or (ii) the defense of an invalidity claim with respect to such other Party’s Know-How or Patent Rights, then, in each case, the general

56

concepts of Section 9.5 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 9.5, 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 9.5, to enforce such Know-How or Patent Rights or defend such invalidity claim).

9.5.                   Enforcement of Patents Against Competitive Infringement.

9.5.1.                  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 a Gene Target 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 9.5.6 below, such written notice will be given within 10 days.

9.5.2.                  Control of Competitive Infringement Proceedings. For any Competitive Infringement with respect to a Product (except for a Discontinued Product) licensed to AstraZeneca under Section 6.1.1, Section 6.1.2 or Section 6.1.3 (as applicable) that occurs after AstraZeneca is granted such license, so long as part of such Proceeding AstraZeneca also enforces any Patent Rights Controlled by AstraZeneca (including any Isis Product-Specific Patents assigned by Isis to AstraZeneca under this Agreement) being infringed that Cover such Product, then AstraZeneca will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding with respect thereto by counsel of its own choice at its own expense, and Isis will have the right, at its own expense, to be represented in that action by counsel of its own choice, however, AstraZeneca will have the right to control such litigation. If AstraZeneca 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 AstraZeneca has commenced good faith negotiations with an alleged infringer for elimination of such Competitive Infringement within such 90 day period), Isis will have the right to initiate and control a Proceeding with respect to such Competitive Infringement by counsel of its own choice, and AstraZeneca will have the right to be represented in any such action by counsel of its own choice at its own expense. Notwithstanding the foregoing, if [***]; provided, however, [***]. Notwithstanding the foregoing, if a Competitive Infringement described under this Section 9.5 involves one or more Licensable [***] Product-Specific Patents and there is an Isis [***]-Field ASO Licensee as contemplated under Section 9.2.4, then the

57

institution, prosecution, and control of a Proceeding with respect thereto will be conducted in the collective interest of, such Isis [***]-Field ASO Licensee and AstraZeneca, and this Section 9.5 will be read and construed in a manner that is consistent with the principles described in Section 9.2.4 except that AstraZeneca will retain sole control in respect of the defense strategy for the Assignable [***] Product-Specific Patents.

9.5.3.                  Joinder.

(a)                     If a Party initiates a Proceeding in accordance with this Section 9.5, the other Party agrees to be joined as a party plaintiff where necessary and to give the first Party reasonable assistance and authority to file and prosecute the Proceeding. Subject to Section 9.5.4, the costs and expenses of each Party incurred pursuant to this Section 9.5.3(a) will be borne by the Party initiating such Proceeding.

(b)                     If one Party initiates a Proceeding in accordance with this Section 9.5.3, the other Party may join such Proceeding as a party plaintiff where necessary for such other Party to seek lost profits with respect to such infringement.

9.5.4.                  Share of Recoveries. Any damages or other monetary awards recovered with respect to a Proceeding brought pursuant to this Section 9.5 will be shared as follows:

(a)                                 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); then

(b)                                 any remaining proceeds will be allocated as follows: (A) if Isis initiates the Proceeding pursuant to Section 9.4.1, Section 9.4.2 or Section 9.4.3, [***]; (B) if AstraZeneca initiates the Proceeding pursuant to Section 9.4.1, AstraZeneca will receive and retain [***]% the remaining proceeds and Isis will receive and retain [***]% of the remaining proceeds; and (C) if AstraZeneca initiates the Proceeding pursuant to Section 9.4.2, [***].

9.5.5.                  Settlement. Notwithstanding anything to the contrary in this ARTICLE 9, neither Party may enter a settlement, consent judgment or other voluntary final disposition of a suit under this ARTICLE 9 that disclaims, limits the scope of, admits the invalidity or unenforceability of, or grants a license, covenant not to ▇▇▇ or similar immunity under a Patent Right Controlled by the other Party without first obtaining the written consent of the Party that Controls the relevant Patent Right.

9.5.6.                  35 USC 271(e)(2) Infringement. Notwithstanding anything to the contrary in this Section 9.5, solely with respect to Licensed Patents that have not been

58

assigned to AstraZeneca under this Agreement for a Competitive Infringement under 35 USC 271(e)(2), the time period set forth in Section 9.5.2 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.

9.6.                            Other Infringement.

9.6.1.                  Jointly-Owned Collaboration Patents. With respect to the infringement in the Field of a Jointly-Owned Collaboration 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 9.6.1 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) (A) if the Parties jointly initiate a Proceeding pursuant to this Section 9.6.1, [***]; and (B) if only one Party initiates the Proceeding pursuant to this Section 9.6.1, [***].

9.6.2.                  Patents Solely Owned by Isis. Isis will retain all rights to pursue an infringement of any Patent Right solely owned by Isis which is other than a Competitive Infringement and Isis will retain all recoveries with respect thereto.

9.6.3.                  Patents Solely Owned by AstraZeneca. AstraZeneca will retain all rights to pursue an infringement of any Patent Right solely owned by AstraZeneca which is other than a Competitive Infringement and AstraZeneca will retain all recoveries with respect thereto.

9.7.                   Patent Listing.

9.7.1.                  AstraZeneca’s Obligations. AstraZeneca will promptly, accurately and completely list, with the applicable Regulatory Authorities during the Agreement Term, all applicable Patent Rights that Cover a Product licensed to AstraZeneca under Section 6.1.1, Section 6.1.2 or Section 6.1.3 (as applicable). Prior to such listings, the Parties will meet, through the Joint Patent Committee, to evaluate and identify all applicable Patent Rights, and AstraZeneca will have the right to review, where reasonable, original records relating to any invention for which Patent Rights are being considered by the Joint Patent Committee for any such listing. Notwithstanding the preceding sentence, AstraZeneca will retain final decision-making authority as to the listing of all applicable Patent Rights for a Product that are not Isis Core

59

Technology Patents, Isis Manufacturing and Analytical Patents or Licensable [***] Product-Specific Patents, regardless of which Party owns such Patent Rights.

9.7.2.                  Isis’ Obligations. Isis will promptly, accurately and completely list, with the applicable Regulatory Authorities during the Agreement Term, all applicable Patent Rights that Cover a Discontinued Product. Prior to such listings, the Parties will meet, through the Joint Patent Committee, to evaluate and identify all applicable Patent Rights, and Isis will have the right to review, where reasonable, original records relating to any invention for which Patent Rights are being considered by the Joint Patent Committee for any such listing. Notwithstanding the preceding sentence, Isis will retain final decision-making authority as to the listing of all applicable Patent Rights for such Discontinued Products, as applicable, regardless of which Party owns such Patent Rights.

9.8.                   CREATE Act. Notwithstanding anything to the contrary in this ARTICLE 9, neither Party will have the right to make an election under the CREATE Act when exercising its rights under this ARTICLE 9 without the prior written consent of the other Party, which will not be unreasonably withheld, conditioned or delayed. With respect to any such permitted election, the Parties will use reasonable efforts to cooperate and coordinate their activities with respect to any submissions, filings or other activities in support thereof. The Parties acknowledge and agree that this Agreement is a “joint research agreement” as defined in the CREATE Act.

9.9.                   Obligations to Third Parties. Notwithstanding any of the foregoing, each Party’s rights and obligations with respect to Licensed Technology under this ARTICLE 9 will be subject to the Third Party rights and obligations under any (i) Third Party agreements the restrictions and obligations of which AstraZeneca has agreed to under Section 8.9.2(a)(ii), Section 8.9.2(b)(i) or Section 8.9.2(b)(ii)(2), (ii) Prior Agreements, and (iii) Isis In-License Agreements; provided, however, that, to the extent that Isis has a non-transferable right to prosecute, maintain or enforce any Patent Rights licensed to AstraZeneca hereunder and, this Agreement purports to grant any such rights to AstraZeneca, Isis will act in such regard with respect to such Patent Rights at AstraZeneca’s direction.

9.10.            Additional Rights and Exceptions. Notwithstanding any provision of this ARTICLE 9, but subject to Section 9.2.4 and Section 9.4.4, Isis retains the sole right to Prosecute and Maintain Isis Core Technology Patents, Isis Manufacturing and Analytical Patents and Licensable [***] Product-Specific Patents during the Agreement Term and to control any enforcement of Isis Core Technology Patents and Isis Manufacturing and Analytical Patents, and will take the lead on such enforcement solely to the extent that the scope or validity of any Patent Rights Controlled by Isis and Covering the Isis Core Technology Patents or Isis Manufacturing and Analytical Patents is at risk.

9.11.            Patent Term Extension. The Parties will cooperate with each other in gaining patent term extension wherever applicable to a Product, and AstraZeneca will determine which Isis Product-Specific Patents will be extended. For clarity, with respect to any Isis

60

Product-Specific Patent for which AstraZeneca has an exclusive license under Section 6.1.1, Section 6.1.2 or Section 6.1.3 (as applicable), as between AstraZeneca and any Third Party granted a license by Isis outside the Field under any such Isis Product-Specific Patents, AstraZeneca will determine which Isis Product-Specific Patents will be extended.

9.12.            No Challenge. As a material inducement for Isis entering into this Agreement, AstraZeneca covenants to Isis that during the Agreement Term, solely with respect to rights to the Licensed Patents that are included in a license granted or that may be granted to AstraZeneca under Section 6.1.1, Section 6.1.2 or Section 6.1.3 (as applicable), AstraZeneca, its Affiliates or Sublicensees will not, in the United States or any other country, (a) commence or otherwise voluntarily determine to participate in (other than as may be necessary or reasonably required to assert a cross-claim or a counter-claim or to respond to a court request or order or administrative law request or order) any action or proceeding, challenging or denying the enforceability or validity of any claim within an issued patent or patent application within such Licensed Patents, or (b) direct, support or actively assist any other Person (other than as may be necessary or reasonably required to assert a cross-claim or a counter-claim or to respond to a court request or order or administrative law request or order) in bringing or prosecuting any action or proceeding challenging or denying the validity of any claim within an issued patent or patent application within such Licensed Patents. For purposes of clarification and without limiting any other available remedies, subject to any applicable cure period provided herein for breaches of this Section 9.12 that are curable (i.e., which would allow AstraZeneca the opportunity to rescind any wrongfully brought actions by it, its Affiliates, or Sublicensees), if AstraZeneca takes any of the actions described in clause (a) or clause (b) of this Section 9.12, AstraZeneca will have materially breached this Agreement and Isis may terminate this Agreement under Section 12.2.2(b).

11.1.            Indemnification by AstraZeneca. AstraZeneca agrees to defend Isis, its Affiliates and their respective directors, officers, stockholders, employees and agents, and their respective successors, heirs and assigns (collectively, the “Isis Indemnitees”), and will indemnify and hold harmless the Isis Indemnitees, from and against any liabilities, losses, costs, damages, fees or expenses payable to a Third Party, and reasonable attorneys’ fees and other legal expenses with respect thereto (collectively, “Losses”) arising out of any claim, action, lawsuit or other proceeding by a Third Party (collectively, “Third Party Claims”) brought against any Isis Indemnitee and resulting from or occurring as a result of: (a) any activities conducted by an AstraZeneca employee, consultant or (sub)contractor in the performance of the AstraZeneca Conducted Activities, (b) the Development or Commercialization of any Compound or Product by AstraZeneca or its Affiliates, Sublicensees or contractors, (c) any breach by AstraZeneca of any of its representations, warranties or covenants pursuant to this Agreement, or (d) the negligence or willful misconduct of AstraZeneca or any AstraZeneca Affiliate or Sublicensee in the performance of this Agreement; except in any such case to the extent such Losses result from: (i) the negligence or willful misconduct of any Isis Indemnitee, (ii) any breach by Isis of any of its representations, warranties, covenants or obligations pursuant to this Agreement, or (iii) any breach of Applicable Law by any Isis Indemnitee.

11.2.            Indemnification by Isis. Isis agrees to defend AstraZeneca, its Affiliates and their respective directors, officers, stockholders, employees and agents, and their respective successors, heirs and assigns (collectively, the “AstraZeneca Indemnitees”), and will indemnify and hold harmless the AstraZeneca Indemnitees, from and against any Losses arising out of Third Party Claims brought against any AstraZeneca Indemnitee and resulting from or occurring as a result of: (a) any activities conducted by an Isis employee, consultant or (sub)contractor in the performance of the Isis Conducted Activities; (b) any breach by Isis of any of its representations, warranties or covenants pursuant to this Agreement, (c) the negligence or willful misconduct of any Isis Indemnitee or any (sub)contractor of Isis in the performance of this Agreement, or (d) the Development or Commercialization of any Discontinued Product by Isis or its Affiliates, Sublicensees or contractors; except in any such case to the extent such Losses result from: (i) the negligence or willful misconduct of any AstraZeneca Indemnitee, (ii) any breach by AstraZeneca of any of its representations, warranties, covenants or obligations pursuant to this Agreement, or (iii) any breach of Applicable Law by any AstraZeneca Indemnitee.

65

11.3.            Notice of Claim. All indemnification claims provided for in Section 11.1 and Section 11.2 will be made solely by such Party to this Agreement (the “Indemnified Party”). The Indemnified Party will give the indemnifying Party prompt written notice (an “Indemnification Claim Notice”) of any Losses or the discovery of any fact upon which the Indemnified Party intends to base a request for indemnification under Section 11.1 or Section 11.2, but in no event will the indemnifying Party be liable for any Losses to the extent such Losses result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party will furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims.

11.4.            Defense, Settlement, Cooperation and Expenses.

11.4.1.           Control of Defense. At its option, the indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within 30 days after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying Party will not be construed as an acknowledgment that the indemnifying Party is liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor will it constitute a waiver by the indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party. In the event the indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party will as soon as is reasonably possible deliver to the indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, except as provided in this Section 11.4.1, the Indemnified Party will be responsible for the legal costs or expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim.

11.4.2.           Right to Participate in Defense. Without limiting Section 11.4.1, any Indemnified Party will be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment will be at the Indemnified Party’s own cost and expense unless (a) the employment thereof has been specifically authorized by the indemnifying Party in writing, (b) the indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 11.4.1 (in which case the Indemnified Party will control the defense), or (c) the interests of the Indemnified Party and the indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both Parties under

66

Applicable Law, ethical rules or equitable principles in which case the indemnifying Party will be responsible for any such costs and expenses of counsel for the Indemnified Party.

11.4.3.           Settlement. With respect to any Third Party Claims relating solely to the payment of money damages in connection with a Third Party Claim and that will not admit liability or violation of Law on the part of the Indemnified Party or result in the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely affecting the business of the Indemnified Party in any manner (such as granting a license or admitting the invalidity of a Patent Right Controlled by an Indemnified Party), and as to which the indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, will deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 11.4.1, the indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld). The indemnifying Party will not be liable for any settlement, consent to entry of judgment, or other disposition of a Loss by an Indemnified Party that is reached without the written consent of the indemnifying Party. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party will admit any liability with respect to or settle, compromise or discharge, any Third Party Claim without the prior written consent of the indemnifying Party, such consent not to be unreasonably withheld.

11.4.4.           Cooperation. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will, and will cause each other Indemnified Party to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation will include access during normal business hours afforded to indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket costs and expenses in connection therewith.

67

11.4.5.           Costs and Expenses. Except as provided above in this Section 11.4, the costs and expenses, including attorneys’ fees and expenses, incurred by the Indemnified Party in connection with any claim will be reimbursed on a Calendar Quarter basis by the indemnifying Party, without prejudice to the indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

11.5.            Insurance.

11.5.1.           Isis’ Insurance Obligations. Isis will maintain, at its cost, reasonable insurance against liability and other risks associated with its activities contemplated by this Agreement, including but not limited to its indemnification obligations herein, in such amounts and on such terms as are customary for prudent practices for biotech companies of similar size and with similar resources in the pharmaceutical industry for the activities to be conducted by it under this Agreement taking into account the scope of development of products. Isis will furnish to AstraZeneca evidence of any insurance required under this Section 11.5.1, upon request.

11.5.2.           AstraZeneca’s Insurance Obligations. AstraZeneca hereby represents and warrants to Isis that it will maintain, at its cost, reasonable insurance against liability and other risks associated with its activities contemplated by this Agreement (including product liability), including but not limited to its indemnification obligations herein, in such amounts and on such terms as are customary for prudent practices for large companies in the pharmaceutical industry for the activities to be conducted by AstraZeneca under this Agreement. AstraZeneca will maintain such self insurance throughout the Agreement Term and for five years thereafter, and will furnish to Isis evidence of such insurance, upon request.

11.6.            LIMITATION OF CONSEQUENTIAL DAMAGES. EXCEPT FOR (a) CLAIMS OF A THIRD PARTY THAT ARE SUBJECT TO INDEMNIFICATION UNDER THIS ARTICLE 11 OR SECTION 12.3.2(i), (b) CLAIMS ARISING OUT OF A PARTY’S WILLFUL MISCONDUCT, (c) A PARTY’S BREACH OF ARTICLE 5, OR A BREACH OF SECTION 12.3.1(a) BY ASTRAZENECA OR ITS AFFILIATES OR (d) CLAIMS ARISING OUT OF A PARTY’S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS UNDER THIS AGREEMENT, NEITHER PARTY NOR ANY OF ITS AFFILIATES WILL BE LIABLE TO THE OTHER PARTY TO THIS AGREEMENT OR ITS AFFILIATES FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE OR OTHER INDIRECT DAMAGES OR LOST OR IMPUTED PROFITS OR ROYALTIES, LOST DATA OR COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN

68

(4)                                 any Person to reward that Person for acting improperly or to induce that Person to act improperly.

11.7.2              Party Representatives shall not, directly or indirectly, solicit, receive or agree to accept any payment of money or anything else of value in violation of the Anti-Corruption Laws.

11.7.3              Each Party acknowledges that its undertakings given in Sections 11.7.1 and 11.7.2 are material to the other Party in entering into a relationship with such Party.

11.7.4              Each Party, on behalf of itself and its Party Representatives, represents and warrants to the other Party that for the term of this Agreement and six years thereafter, it shall and shall procure that its Party Representatives keep and maintain accurate books and reasonably detailed records in connection with the performance of its obligation under this Agreement including all records required to establish compliance with Sections 11.7.1 and 11.7.2 above.

ARTICLE 12.
TERM; TERMINATION

12.1.            Agreement Term; Expiration. This Agreement is effective as of the Effective Date and, unless earlier terminated pursuant to the other provisions of this ARTICLE 12, will continue in full force and effect until this Agreement expires as follows:

12.1.1.           on a country-by-country and Product-by-Product basis, on the date of expiration of all payment obligations by the Commercializing Party under this Agreement with respect to such Product (or such Discontinued Product) in such country; and

12.1.2.           in its entirety upon the expiration of all payment obligations under this Agreement with respect to the last Product (or last Discontinued Product) in all countries pursuant to Section 12.1.1.

70

The period from the Effective Date until the date of expiration of this Agreement pursuant to this Section 12.1 is the “Agreement Term.”

12.2.            Termination of the Agreement.

12.2.1.           AstraZeneca’s Termination for Convenience or Change of Control.

(a)                                 Termination for Convenience. At any time following payment by AstraZeneca of the upfront fee under Section 8.1, subject to Section 12.3.1 below, AstraZeneca will be entitled to terminate this Agreement in part with respect to STAT3 Products or [***] Products for convenience by providing 90 days written notice to Isis of such termination. In addition, at any time following payment by AstraZeneca of the upfront fee under Section 8.1 and the payment under Section 8.3, subject to Section 12.3.1 below, AstraZeneca will be entitled to terminate this Agreement in its entirety or in part on a Product-by-Product, Gene Target-by-Gene Target basis for convenience by providing 90 days written notice to Isis of such termination.

(b)                                 Change of Control Event. Prior to the Option Deadline for an Oncology Target or until Isis has completed the Isis Conducted Activities with respect to the STAT3 Program or [***] Program under the R&D Research and Development Plan, AstraZeneca will have the right to terminate this Agreement in whole or in part with respect to one or more Oncology Targets for which AstraZeneca has not exercised its Option or with respect to a Licensed Target, immediately upon written notice to Isis provided at any time within 30 Business Days following notification by Isis to AstraZeneca of the closing of a Change of Control Event (and Isis shall be obliged to give notice on such closing, and in the event it fails to do so, AstraZeneca’s right to terminate may be exercised within 90 Business Days of such closing coming to AstraZeneca’s Knowledge), if such closing occurs during the Oncology Collaboration Term or before Isis has completed the Isis Conducted Activities with respect to the STAT3 Program or [***] Program under the R&D Research and Development Plan (as applicable). If at AstraZeneca’s discretion, AstraZeneca decides not to terminate this Agreement with respect to a particular Gene Target pursuant to this Section 12.2.1(b) following the closing of a Change of Control Event during the Oncology Collaboration Term, then, subject to the below provisions in this Section 12.2.1, Isis’ and AstraZeneca’s obligations under ARTICLE 3 to perform the relevant Collaboration Program on such Gene Target will remain and Isis (or its successor) will use commercially reasonable efforts to perform the Oncology Collaboration Program on such Oncology Target in accordance with ARTICLE 3 while, to the extent reasonably practicable, maintaining confidentiality of AstraZeneca’s Confidential Information from any entity acquiring Isis as a result of the Change of Control Event. As soon as reasonably possible after the public announcement of such a Change of

71

Control Event, Isis (or its successor) and AstraZeneca will meet to discuss in good faith how Isis (or its successor) will continue to perform its obligations under this Agreement with respect to any Licensed Targets and Oncology Targets for which AstraZeneca has not exercised its Option so that AstraZeneca can consider whether to exercise its rights of termination under this Section 12.2.1(b).  If AstraZeneca does not exercise its right of termination it shall have the right, by providing Isis with written notice within 30 Business Days following notification by Isis to AstraZeneca of the closing of a Change of Control Event, to require that Isis ceases performing any or certain activities and co-operate and take such measures as may be requested to ensure a prompt and smooth transition of such activities to AstraZeneca or its designee. AstraZeneca shall be entitled to deduct an amount equal to the [***]) from its next applicable milestone or license fee payment as applicable. Without prejudice to the foregoing, if requested by AstraZeneca such measures shall include a technology transfer pursuant to the provisions of Section 6.5 or Section 6.1.4(b), in either case without charge to AstraZeneca.  Furthermore, if the surviving entity following such Change of Control Event is clinically developing or commercializing a product that is directly competing with a Product under this Agreement, then, solely with respect to the Product that is subjected to such competition, AstraZeneca will no longer be bound by the disclosure requirements of Section 4.3 hereof and may require that Isis cease to participate in the JSC.

12.2.2.           Termination for Material Breach.

(a)                     AstraZeneca’s Right to Terminate. If AstraZeneca has reason to believe that Isis is in material breach of this Agreement (other than with respect to a failure to use Commercially Reasonable Efforts under ARTICLE 1, ARTICLE 2 or ARTICLE 3, which is governed by Section 12.2.3 below), then AstraZeneca may deliver notice of such material breach to Isis. If the breach is curable, Isis will have 60 days to cure such breach. If Isis fails to cure such breach within the 60 day period, or if the breach is not subject to cure, AstraZeneca may terminate this Agreement in its entirety if such breach relates to this Agreement in its entirety, or in relevant part on a Product-by-Product, Gene Target-by-Gene Target basis if such breach does not relate to this Agreement in its entirety, by providing written notice to Isis.

(b)                     Isis’ Right to Terminate. If Isis has reason to believe that AstraZeneca is in material breach of this Agreement (other than with respect to a failure to use Commercially Reasonable Efforts under ARTICLE 1, ARTICLE 2, ARTICLE 3 or Section 7.1, which is governed by Section 12.2.3 below), then Isis may deliver notice of such material breach to AstraZeneca. If the breach is curable, AstraZeneca will have 60 days to cure such breach (except to the extent such breach involves the failure to make a payment

72

when due, which breach must be cured within 30 days following such notice). If AstraZeneca fails to cure such breach within the 60 day or 30 day period, as applicable, or if the breach is not subject to cure, Isis may terminate this Agreement in its entirety if such breach relates to this Agreement in its entirety, or in relevant part on a Product-by-Product, Gene Target-by-Gene Target basis if such breach does not relate to this Agreement in its entirety, by providing written notice to AstraZeneca.

12.2.3.           Remedies for Failure to Use Commercially Reasonable Efforts.

(a)                     If Isis fails to use Commercially Reasonable Efforts as contemplated in ARTICLE 1, ARTICLE 2 or ARTICLE 3 (as determined in accordance with Section 14.1), AstraZeneca will notify Isis and, within 30 days thereafter, Isis and AstraZeneca will meet and confer to discuss and resolve the matter in good faith, and attempt to devise a mutually agreeable plan to address any outstanding issues related to Isis’ use of Commercially Reasonable Efforts in ARTICLE 1, ARTICLE 2 or ARTICLE 3. Following such a meeting, if Isis fails to use Commercially Reasonable Efforts as contemplated in ARTICLE 1, ARTICLE 2 or ARTICLE 3, then subject to Section 12.2.4 below, AstraZeneca will have the right, at its sole discretion, to terminate this Agreement in whole or in part on a Product-by-Product, Gene Target-by-Gene Target basis.

(b)                     If AstraZeneca fails to use Commercially Reasonable Efforts as contemplated in ARTICLE 1, ARTICLE 2, ARTICLE 3 or Section 7.1 (as determined in accordance with Section 14.1), Isis will notify AstraZeneca and, within 30 days thereafter, Isis and AstraZeneca will meet and confer to discuss and resolve the matter in good faith, and attempt to devise a mutually agreeable plan to address any outstanding issues related to AstraZeneca’s use of Commercially Reasonable Efforts in ARTICLE 1, ARTICLE 2, ARTICLE 3 or Section 7.1. Following such a meeting, if AstraZeneca fails to use Commercially Reasonable Efforts as contemplated in ARTICLE 1, ARTICLE 2, ARTICLE 3 or Section 7.1, then subject to Section 12.2.4 below, Isis will have the right, at its sole discretion, to terminate this Agreement in part on a Product-by-Product, Gene Target-by-Gene Target basis.

12.2.4.           Disputes Regarding Material Breach. Notwithstanding the foregoing, if the Breaching Party in Section 12.2.2 or Section 12.2.3 disputes in good faith the existence, materiality, or failure to cure of any such breach which is not a payment breach, and provides notice to the Non-Breaching Party of such dispute within such 60 day period, the Non-Breaching Party will not have the right to terminate this Agreement in accordance with Section 12.2.2 or Section 12.2.3, unless and until it has been determined in accordance with Section 14.1 that this Agreement was materially breached by the Breaching Party and the Breaching Party fails to cure such breach within 30 days following such determination. It is understood and acknowledged that during the pendency of

73

such dispute, all the terms and conditions of this Agreement will remain in effect and the Parties will continue to perform all of their respective obligations hereunder, including satisfying any payment obligations.

12.2.5.           Termination for Insolvency.

(a)                     Either Party may terminate this Agreement if, at any time, the other Party files in any court or agency pursuant to any statute or regulation of any state or country a petition in bankruptcy or insolvency or for the appointment of a receiver or trustee of the Party or of substantially all of its assets; or if the other Party proposes a written agreement of composition or extension of substantially all of its debts; or if the other Party will be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition will not be dismissed within 90 days after the filing thereof; or if the other Party will propose or be a party to any dissolution or liquidation; or if the other Party will make an assignment of substantially all of its assets for the benefit of creditors.

(b)                     All rights and licenses granted under or pursuant to any section of this Agreement are and will otherwise be deemed to be for purposes of Section 365(n) of ▇▇▇▇▇ ▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇ Code (the “Bankruptcy Code”) or analogous provisions of Applicable Law outside the US licenses of rights to “intellectual property” as defined in Section 101(56) of the Bankruptcy Code or analogous provisions of Applicable Law outside the US. The Parties will retain and may fully exercise all of their respective rights and elections under the Bankruptcy Code or analogous provisions of Applicable Law outside the US. Upon the commencement of a bankruptcy proceeding of any Party, the non-bankrupt Party will further be entitled to a complete duplicate of, or complete access to, any such intellectual property, and all embodiments which, if not already in its possession, will be promptly delivered to the non-bankrupt Party upon written request.

12.3.            Consequences of Expiration or Termination of this Agreement.

12.3.1.           Consequence of Termination of this Agreement. If this Agreement is terminated by a Party in accordance with this ARTICLE 12 in its entirety or on a Product-by-Product, Gene Target-by-Gene Target basis (including under Section 1.2.3, Section 2.2.3 or Section 2.2.4(b)) at any time and for any reason, the following terms will apply to any such termination, but only to the extent of any such termination (i.e., in part or in its entirety):

(a)                                 Licenses. The licenses granted by Isis to AstraZeneca under this Agreement will terminate and AstraZeneca, its Affiliates, Sublicensees and Distributors will cease selling Products; provided, that AstraZeneca, its Affiliates, Sublicensees and Distributors shall have the right to sell any

74

remaining inventory of Product over a period of no greater than six months after the effective date of such termination, and AstraZeneca will pay Isis royalties in accordance with Section 8.8 on the Net Sales of such inventory of such Products, to the extent not already paid.

(b)                                 Option. AstraZeneca’s Option will terminate with respect to any terminated Oncology Target.

Notwithstanding the foregoing, the Parties will be permitted to retain one copy of such data, files, records, and other materials for archival and legal compliance purposes.

(f)                                   Accrued Rights. Termination of this Agreement for any reason will be without prejudice to any rights or financial compensation that will have accrued to the benefit of a Party prior to such termination. Such termination will not relieve a Party from obligations that are expressly indicated to survive the termination of this Agreement. For purposes of clarification, milestone payments under ARTICLE 8 accrue as of the date the applicable milestone event is achieved even if the payment is not due at that time.

Except to the extent required to comply with Applicable Law, regulation, rule or legal process or as otherwise permitted in accordance with this Section 13.4, each Party agrees not to issue any other press release or other public statement disclosing other information relating to this Agreement or the terms of this Agreement or the transactions contemplated hereby without the prior written consent of the other Party, which consent will not be unreasonably withheld or delayed.

79

13.4.2.           Use of Name. Except as set forth in Section 13.4.8, neither Party will use the other Party’s name in a press release or other publication without first obtaining the prior consent of the Party to be named.

13.4.3.           Notice of Significant Events. Each Party will immediately notify (and provide as much advance notice as possible, but at a minimum three Business Days advance notice to) the other of any significant event related to a Product (including any data or regulatory advice or approval) so that the Parties may analyze the need to or desirability of publicly disclosing or reporting such event. Notwithstanding Section 13.4.1 above, any press release or other similar public communication by either Party related to a Product’s efficacy or safety data and/or results, will be submitted to the other Party for review and approval at least three Business Days in advance of such proposed public disclosure, which approval will not be unreasonably withheld or delayed.

13.4.4.           Disclosure of Information Related to Products. The Party that has primary control of a Product (i.e., Isis, with respect to Products for which AstraZeneca has not exercised its Option; and AstraZeneca, with respect to STAT3 Products, [***] Products and Products for which AstraZeneca has exercised its Option) has the sole right, consistent with its practice with its other products, to issue press releases or other similar public communications to disclose the progress and results regarding such Product to the public in order to satisfy its disclosure obligations under Applicable Law or to remain consistent with its normal public disclosure practices (but for clarity, in connection with the Oncology Collaboration, such disclosure would not involve disclosing a Reserved Target or an Oncology Lead Candidate until such target had become a Development Candidate) ; provided, that any proposed press release or other similar public communication by such controlling Party disclosing regulatory discussions, the efficacy or safety data or results related to the Product or such controlling Party’s sales projections, (i) such controlling Party will submit such proposed communication to the non-controlling Party for review at least two Business Days in advance of such proposed public disclosure, (ii) the non-controlling Party will have the right to review and recommend changes to such communication, and (iii) the controlling Party will in good faith consider any changes that are timely recommended by the non-controlling Party. In addition, if at any time during such two Business Day review period, the other Party informs such Party that its proposed public disclosure discloses inventions made by either Party in the course of the research or development under this Agreement that have not yet been protected through the filing of a patent application, or the public disclosure could be expected to have a material adverse effect on any Patent Rights or Know-How solely owned or Controlled by such other Party, then such Party will either (x) delay such proposed publication for a period of time reasonably necessary to permit the timely preparation and first filing of patent application(s) on the information involved, or (y) to the extent permitted by Applicable Law, remove the identified information prior to disclosure. While the Parties acknowledge that it may be

80

interpreted that there is overlap between this Section 13.4.4 and Section 13.4.5, for clarity, the Parties intend for this Section 13.4.4 to address public disclosures that are not primarily of a scientific or scholarly nature (which are meant to be disclosed in accordance with Section 13.4.5 below) but rather this Section 13.4.4 is designed to address more urgent disclosures required under Applicable Law or to provide investors with material information regarding Products or this Agreement in a timely manner so that they may make informed investment decisions in Isis’ or AstraZeneca’s stock.

13.4.5.           Scientific or Clinical Presentations. Regarding any proposed scientific publications or public presentations related to summaries of results from any Clinical Studies generated by Isis or AstraZeneca for a Product, the Parties acknowledge that scientific lead time is a key element of the value of a Product under this Agreement and further agree to use Commercially Reasonable Efforts to control public scientific disclosures of the results of the research or development activities under this Agreement to prevent any potential adverse effect of any premature public disclosure of such results, for example, without limitation, intellectual property protection, competitive intelligence, prejudicing the optimal presentation at major meetings. For clarity, in connection with the Oncology Collaboration, such disclosure would not involve disclosing a Reserved Target or an Oncology Lead Candidate until such target had become a Development Candidate unless agreed otherwise by the Parties. The Parties will establish a procedure for publication review and each Party will first submit to the other Party through the Joint Patent Committee an early draft of all such publications or presentations, whether they are to be presented orally or in written form, at least 30 days prior to submission for publication including to facilitate the publication of any summaries of Clinical Studies data and results as required on the clinical trial registry of each respective Party. Each Party will review such proposed publication in order to avoid the unauthorized disclosure of a Party’s Confidential Information and to preserve the patentability of inventions arising from the Collaboration Plans. If, during such 30 day period, the other Party informs such Party that its proposed publication contains Confidential Information of the other Party, then such Party will delete such Confidential Information from its proposed publication. In addition, if at any time during such 30 day period, the other Party informs such Party that its proposed publication discloses inventions made by either Party in the course of the research or development under this Agreement that have not yet been protected through the filing of a patent application, or the public disclosure of such proposed publication could be expected to have a material adverse effect on any Patent Rights or Know-How solely owned or Controlled by such other Party, then such Party will either (i) delay such proposed publication for up to 60 days from the date the other Party informed such Party of its objection to the proposed publication, to permit the timely preparation and first filing of patent application(s) on the information involved or (ii) remove the identified disclosures prior to publication.

81

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

13.4.7.           Subsequent Disclosure. Notwithstanding the foregoing, to the extent information regarding this Agreement or the Product has already been publicly disclosed, either Party (or its Affiliates) may subsequently disclose the same information to the public without the consent of the other Party.

13.4.8.           Acknowledgment. Each Party will acknowledge in any press release, public presentation or publication regarding the collaboration or the Product, the other Party’s role in discovering and developing the Product or Discontinued Product, as applicable, that the Product is under license from Isis and otherwise acknowledge the contributions from the other Party, and each Party’s stock ticker symbol (e.g., Nasdaq: ISIS; ▇▇▇: AZN). Isis may include the Product (and identify AstraZeneca as its partner for the Product) in Isis’ drug pipeline.

MISCELLANEOUS

14.1.            Dispute Resolution.

14.1.1.           Resolution by Senior Representatives. The Parties will seek to settle amicably any and all disputes, controversies or claims arising out of or in connection with this Agreement. For clarity, any decision within the JSC’s decision-making authority will be finally decided by the JSC. Any dispute between the Parties which is outside the JSC’s decision-making authority will be promptly presented to the Senior Vice President, Research of AstraZeneca and the Chief Operating Officer of Isis (the “Senior Representatives”), or their respective designees, for resolution. Such Senior Representatives, or their respective designees, will meet in-person or by teleconference as soon as reasonably possible thereafter, and use their good faith efforts to mutually agree upon the resolution of the dispute, controversy or claim. Any dispute within the JSC’s decision-making authority will not be subject to arbitration.

14.1.2.           Request for Arbitration. If after negotiating in good faith pursuant to Section 14.1.1, the Parties fail after good faith discussions undertaken within reasonable promptness, to reach an amicable agreement within 90 days, then either Party may upon written notice to the other submit to binding arbitration pursuant to Section 14.1.3 below. No statements made by either Party during such discussions will be used by the other Party or admissible in arbitration or any other subsequent proceeding for resolving the dispute.

82

14.1.3.           Arbitration.

(a)                                 Subject to Section 14.2, any dispute, claim or controversy arising from or related in any way to this Agreement or the interpretation, application, breach, termination or validity thereof, including any claim of inducement of this Agreement by fraud or otherwise, not resolved under the provisions of Section 14.1.1 will be resolved by final and binding arbitration conducted in accordance with the terms of this Section 14.1.3. The arbitration will be held in New York, New York, USA according to Rules of Arbitration of the International Chamber of Commerce (“ICC”). The arbitration will be conducted by a panel of three arbitrators with significant experience in the pharmaceutical industry, unless otherwise agreed by the Parties, appointed in accordance with applicable ICC rules. Any arbitration herewith will be conducted in the English language to the maximum extent possible. The arbitrators will render a written decision no later than six months following the selection of the arbitrators, including a basis for any damages awarded and a statement of how the damages were calculated. Any award will be promptly paid in U.S. dollars free of any tax, deduction or offset. Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Section 14.1.3. With respect to money damages, nothing contained herein will be construed to permit the arbitrator or any court or any other forum to award punitive or exemplary damages, except in the case of breach of ARTICLE 13. By entering into this agreement to arbitrate, the Parties expressly waive any claim for punitive or exemplary damages, except in the case of breach of ARTICLE 13. Each Party will pay its legal fees and costs related to the arbitration (including witness and expert fees). Judgment on the award so rendered will be final and may be entered in any court having jurisdiction thereof.

(b)                                 EACH PARTY HERETO WAIVES ITS RIGHT TO TRIAL OF ANY ISSUE BY JURY. EACH PARTY HERETO WAIVES ANY CLAIM FOR ATTORNEYS’ FEES AND COSTS AND PREJUDGMENT INTEREST FROM THE OTHER.

14.1.4.           Court Actions. Nothing contained in this Agreement will deny either Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing dispute resolution discussions or arbitration proceeding. In addition, either Party may bring an action in any court of competent jurisdiction to resolve disputes pertaining to the validity, construction, scope, enforceability, infringement or other violations of patents or other proprietary or intellectual property rights, and no such claim will be subject to arbitration pursuant to Section 14.1.3.

14.2.            Governing Law; Jurisdiction; Equitable Relief, Losses.

14.2.1.           This Agreement will be governed by and construed and enforced in accordance with the laws of the State of New York, USA, without reference to any rules of

83

conflicts of laws. For clarification, any dispute relating to the scope, validity, enforceability or infringement of any Patents will be governed by and construed and enforced in accordance with the patent laws of the applicable jurisdiction.

14.2.2.           Each Party acknowledges and agrees that the restrictions set forth in Section 5.1 of this Agreement are reasonable and necessary to protect the legitimate interests of the other Party and that the other Party would not have entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any of these provisions will probably result in irreparable injury to the other Party for which there will be no adequate remedy at law. In the event of a breach or threatened breach of any such provision, each Party will be authorized and entitled to obtain from any court of competent jurisdiction equitable relief, whether preliminary or permanent, specific performance and an equitable accounting of all earnings, profits and other benefits arising from such breach, which rights will be cumulative and in addition to any other rights or remedies to which such Party may be entitled in law or equity. Each Party agrees to waive any requirement that the other Party (a) post a bond or other security as a condition for obtaining any such relief, and (b) show irreparable harm, balancing of ▇▇▇▇▇, consideration of the public interest or inadequacy of monetary damages as a remedy. Nothing in this Section 14.2.2 is intended, or should be construed, to limit a Party’s rights to equitable relief or any other remedy for a breach of any other provision of this Agreement. Except for (i) the offsets and credits explicitly set forth in Section 8.9.2(a), Section 8.9.4(b) and Section 8.11, (ii) any amount awarded to be paid by one Party to the other by the panel of arbitrators in a final and binding arbitration proceeding adjudicated under Section 14.1.3, and (iii) any offset of undisputed but unpaid amounts under this Agreement, neither Party will have the right to setoff any amount it is owed or believes it is owed against payments due or payable to the other Party under this Agreement.

14.2.3.           Neither Party will be entitled to recover any Losses relating to any matter arising under one provision of this Agreement to the extent that such Party has already recovered Losses with respect to such matter pursuant to other provisions of this Agreement (including recoveries under Section 11.1 or Section 11.2, and the offsets under Section 8.9.4(b)).

14.3.            Assignment and Successors. Neither this Agreement nor any obligation of a Party hereunder may be assigned by either Party without the consent of the other, which will not be unreasonably withheld, delayed or conditioned, except that each Party may assign this Agreement and the rights, obligations and interests of such Party, in whole or in part, without the other Party’s consent, to any of its Affiliates, to any purchaser of all or substantially all of its assets to which this Agreement relates or to any successor corporation resulting from any merger, consolidation, share exchange or other similar transaction; provided, if a Party transfers or assigns this Agreement to [***] described in this Agreement, then such transferring Party (or such Affiliate) (“Transferring Party”),

84

will [***] due that the Transferring Party is obligated to pay to the non-transferring Party (“Non-Transferring Party”) under ARTICLE 8 for the [***] such that the Non-Transferring Party receives [***]. In addition, Isis may assign or transfer its rights to receive payments under this Agreement (but no liabilities), without AstraZeneca’s consent, to an Affiliate or to a Third Party in connection with a payment factoring transaction; provided, however, that Isis will provide AstraZeneca advance notice of any such proposed payment factoring transaction giving AstraZeneca a reasonable opportunity to provides comments (which Isis will consider in good faith); [***]. Any purported assignment or transfer made in contravention of this Section 14.3 will be null and void.

To the extent the Non-Transferring Party utilizes a [***] in any year, the Non-Transferring Party will [***] the Transferring Party [***]. To assist the Transferring Party in determining when a [***] pursuant to the foregoing sentence, beginning with the first Annual tax return for the year in which the Transferring Party [***] payment under this Section 14.3, and each year thereafter (including, for clarity, all years in which the Non-Transferring Party [***] or [***]), the Non-Transferring Party will provide the Transferring Party with the Non-Transferring Party s’ Annual tax returns (federal and state) and, in years in which the Non-Transferring Party utilizes the [***], supporting documentation for such [***].

14.4.            Force Majeure. No Party will be held responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in performing any obligation of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For purposes of this Agreement, force majeure means a cause beyond the reasonable control of a Party, which may include acts of God; acts, regulations, or laws of any government; war; terrorism; civil commotion; fire, flood, earthquake, tornado, tsunami, explosion or storm; pandemic; epidemic and failure of public utilities or common carriers. In such event the Party so failing or delaying will immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice will be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled for up to a maximum of 90 days, after which time the Parties will negotiate in good faith any modifications of the terms of this Agreement that may be necessary to arrive at an equitable solution, unless the Party giving such notice has set out a reasonable timeframe and plan to resolve the effects of such force majeure and executes such plan within such timeframe.  To the extent possible, each Party will use reasonable efforts to minimize the duration of any force majeure.

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

85

or to such other address for such Party as it will have specified by like notice to the other Party; provided that notices of a change of address will be effective only upon receipt thereof.  If delivered personally or by facsimile transmission, the date of delivery will be deemed to be the date on which such notice or request was given.  If sent by overnight express courier service, the date of delivery will be deemed to be the next Business Day after such notice or request was deposited with such service.  If sent by certified mail, the date of delivery will be deemed to be the third Business Day after such notice or request was deposited with the U.S. Postal Service. It is understood and agreed that this Section is not intended to govern the day to day business communications necessary between the parties in performing their duties, in due course, under the terms of this Agreement.

14.6.            Export Clause. Each Party acknowledges that the laws and regulations of the United States restrict the export and re-export of commodities and technical data of United States origin.  Each Party agrees that it will not export or re-export restricted commodities or the technical data of the other Party in any form without the appropriate United States and foreign government licenses.

14.7.            Waiver. Neither Party may waive or release any of its rights or interests in this Agreement except in writing.  The failure of either Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement will not constitute a

86

waiver of that right or excuse a similar subsequent failure to perform any such term or condition.  No waiver by either Party of any condition or term in any one or more instances will be construed as a continuing waiver or subsequent waiver of such condition or term or of another condition or term.

14.8.            Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable by a court of competent jurisdiction, such adjudication will not affect or impair, in whole or in part, the validity, enforceability, or legality of any remaining portions of this Agreement. All remaining portions will remain in full force and effect as if the original Agreement had been executed without the invalidated, unenforceable or illegal part.

14.9.           Entire Agreement; Modifications. This Agreement (including the attached Appendices and Schedules) sets forth and constitutes the entire agreement and understanding between the Parties with respect to the subject matter hereof, and all prior agreements, understanding, promises and representations, whether written or oral, with respect thereto are superseded hereby. Each Party confirms that it is not relying on any representations or warranties of the other Party except as specifically set forth herein. No amendment, modification, release or discharge will be binding upon the Parties unless in writing and duly executed by authorized representatives of both Parties.

14.10.    Relationship of the Parties. It is expressly agreed that the Parties will be independent contractors of one another and that the relationship between the Parties will not constitute a partnership, joint venture or agency.

14.11.    Interpretation. Except as otherwise explicitly specified to the contrary, (a) references to a section, exhibit or schedule means a section of, or schedule or exhibit to this Agreement, unless another agreement is specified, (b) the word “including” (in its various forms) means “including without limitation,” (c) the words “will” and “shall” have the same meaning, (d) references to a particular statute or regulation include all rules and regulations thereunder and any predecessor or successor statute, rules or regulation, in each case as amended or otherwise modified from time to time, (e) references to a particular Person include such Person’s successors and assigns to the extent not prohibited by this Agreement, (f) unless otherwise specified, “$” is in reference to United States dollars, and (g) the headings contained in this Agreement, in any exhibit or schedule to this Agreement and in the table of contents to this Agreement are for convenience only and will not in any way affect the construction of or be taken into consideration in interpreting this Agreement.

14.12.    Books and Records. Any books and records to be maintained under this Agreement by a Party or its Affiliates or Sublicensees will be maintained in accordance with generally accepted accounting principles, or in the case of non-United States sales, other applicable accounting standards, consistently applied.

14.13.    Further Actions. Each Party will execute, acknowledge and deliver such further instruments, and do all such other acts, as may be necessary or appropriate in order to carry out the expressly stated purposes and the clear intent of this Agreement.

87

14.14.    Construction of Agreement. The terms and provisions of this Agreement represent the results of negotiations between the Parties and their representatives, each of which has been represented by counsel of its own choosing, and neither of which has acted under duress or compulsion, whether legal, economic or otherwise. Accordingly, the terms and provisions of this Agreement will be interpreted and construed in accordance with their usual and customary meanings, and each of the Parties hereto hereby waives the application in connection with the interpretation and construction of this Agreement of any rule of law to the effect that ambiguous or conflicting terms or provisions contained in this Agreement will be interpreted or construed against the Party whose attorney prepared the executed draft or any earlier draft of this Agreement.

14.15.    Supremacy. In the event of any express conflict or inconsistency between this Agreement and any Schedule or Appendix hereto, the terms of this Agreement will apply. The Parties understand and agree that the Schedules and Appendices hereto are not intended to be the final and complete embodiment of any terms or provisions of this Agreement, and are to be updated from time to time during the Agreement Term, as appropriate and in accordance with the provisions of this Agreement.

14.16.    Counterparts. This Agreement may be signed in counterparts, each of which will be deemed an original, notwithstanding variations in format or file designation which may result from the electronic transmission, storage and printing of copies of this Agreement from separate computers or printers. Facsimile signatures and signatures transmitted via electronic mail in PDF format will be treated as original signatures.
