All information contained in the Isis Notification or provided pursuant to the due diligence investigation contemplated by the next sentence will be considered Confidential Information of Isis and subject to ARTICLE 8 and will be used by Lilly solely for the purpose of evaluating its interest in exercising its rights under this ARTICLE 6. After receipt of the Isis Notification, Lilly may, upon [***] days prior notice to Isis, have access to [***] available information regarding the Product and access to Isis personnel so that Lilly conduct a customary due diligence investigation.

6.4 Within [***] days after receipt of the Isis Notification (the “Lilly Response Period”), Lilly will either (i) notify Isis that Lilly is interested in the Product, including a written proposal of the terms that Lilly intends to form the basis of a final agreement for the development and commercialization of the Product (a “Lilly Expression of Interest”); or (ii) exercise its Product option to the extent permitted under ARTICLE 5 above; or (iii) notify Isis that Lilly has no interest in the development and commercialization of the Product.

6.5 If Lilly provides Isis with a Lilly Expression of Interest prior to the termination of the Lilly Response Period, then the Parties will negotiate exclusively in good faith reasonable terms that are intended to form the basis of a final agreement for a period of up to [***] days from the date of Lilly’s Expression of Interest.

6.6 If, (i) Lilly fails to provide Isis with a Lilly Expression of Interest or exercise its option prior to the termination of the Lilly Response Period; or (ii) Lilly notifies Isis that Lilly has no interest in the development and commercialization of the Product; or (iii) despite good faith negotiations, Lilly and Isis are unable to reach an agreement by the [***] day following Isis’ receipt of a Lilly Expression of Interest; then, in each case, Isis will thereafter be free to develop the Product on its own or execute a license with an alternative partners with respect to the development and commercialization of the Product; provided, however, that in the event of (iii) of this Section 6.6, then Lilly shall have a period of [***] days following the [***] day in which to exercise its option.

6.6.1 milestone payments and upfront license fees offered by any Third Party and accepted by Isis for the Product must exceed (on a net present value basis) those set forth in the Lilly’s last written proposal by [***] percent ([***]%). The discount rate for the net present value calculation will be the prime rate published in the Wall Street Journal (print or Internet addition) at the time of negotiation plus [***] percent ([***]%). For the

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80(b)4, AND 240.24b-2

purpose of calculating net present value under this Section 6.6 the following timing definitions will apply: (i) Phase III Study Initiation will be considered to begin [***] years after the [***] Study Initiation; (ii) Registration Submission will be considered to occur [***] years from Phase III Study Initiation; and (iii) First Commercial Sale will be considered to occur [***] year after Registration submission.

6.6.3. All other terms and conditions of the third party offer, taken as a whole, are not materially worse than those terms and conditions offered by Lilly.

6.7 Isis will [***] the terms of any such proposed Third Party agreement to [***], and in the event that Lilly in good faith disputes that such terms meet the requirements of Section 6.6, then an independent Third Party with the requisite expertise, selected by the Parties, will make such determination. The expense of such independent Third Party will be shared equally by the Parties. In the event that any Third Party terms include non-monetary consideration (e.g., licensing of patent rights), then such independent Third Party will value such non-monetary consideration as well as any other terms offered by such Third Party and decide whether as a whole the Third Party offer exceeds the Lilly offer as set forth above.

6.8 If a Third Party offer for the Isis Product exceeds the last written terms offered by Lilly by the guidelines outlined in Section 6.6 and is accepted by Isis, Lilly will still be entitled to receive from Isis the running royalty in accordance with Section 7.2 below. .

6.9 If Lilly provides Isis with a timely Lilly Expression of Interest, pursuant to Section 6.5, but Isis does not enter into an agreement with Lilly or reach a mutually agreed-upon term sheet that represents a [***] from a Third Party approved by an officer of the company of such Third Party with respect to the development and commercialization of the Product pursuant to the provisions of Section 6.6 on or before the date Isis publicly announces [***] or a [***] of [***] of a [***] for the Product (i.e. where Isis has not previously publicly announced any [***] from such [***]), then the Lilly Right of First Negotiation with respect to such Product will be revived. For purposes of clarity, if the Lilly Right of First Negotiation is not revived under this Section 6.9 because there was a mutually agreed-upon term sheet that represents a [***] from a Third Party approved by an officer of the company of such Third Party, then, if the transaction contemplated by such term sheet is later abandoned by Isis and such Third Party, then the Lilly Right of First Negotiation will be revived following the date of such abandonment.

6.10 Notwithstanding the other provisions of this ARTICLE 6, the Lilly Right of First Negotiation will automatically expire and terminate upon the exercise or expiration of Lilly’s option under ARTICLE 5.

9.6 Isis’s Right to Indemnification. Lilly will indemnify each of Isis, its Affiliates, Licensees, successors and assigns, and the directors, officers, employees, agents and counsel thereof (the “Isis Indemnitees”), and defend and hold each Isis Indemnitee harmless from and against any and all Damages incurred by or asserted against any Isis Indemnitee of whatever kind or nature, including, without limitation, any claim or liability based upon negligence, warranty, strict liability, violation of government regulation but only to the extent arising from or occurring as a result of a Third Party Claim against any Isis Indemnitee arising because of: (a) breach of any representation or warranty made by Lilly pursuant to this Article 9; (b) any material breach of this Agreement by Lilly; and/or (c) violation of the trade secrets of any Third Party by Lilly; except, in each such case, in subparagraphs (a) through (c) above, to the extent that such Damages are finally determined to have resulted from the negligence or misconduct of a Isis Indemnitee, or the breach of any representation or warranty under Section 9.2 by Isis.

9.7 Indemnification Procedures. Promptly after a Party entitled to indemnification under Section 9.5 or 9.6 (an “Indemnitee”) receives notice of any pending or threatened claim against it (an “Action”), such Indemnitee will give written notice to the Party to whom the Indemnitee is entitled to look for indemnification pursuant to Section 9.5 or 9.6, as applicable (the “Indemnifying Party”), of the commencement thereof, provided that the failure so to notify the Indemnifying Party will not relieve it of any liability that it may have to any Indemnitee hereunder, except to the extent the Indemnifying Party demonstrates that it is prejudiced thereby. In case any Action that is subject to indemnification under this ARTICLE 9, will be brought against an Indemnitee and it will give written notice to the Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to participate therein and, if it so desires, to assume the defense thereof with counsel reasonably satisfactory to such Indemnitee and, after notice from the Indemnifying Party to the Indemnitee of its election to assume the defense thereof, the Indemnifying Party will not be liable to such Indemnitee under this ARTICLE 9 for any fees of other counsel or any other expenses, in each case subsequently incurred by such Indemnitee in connection with the defense thereof, other than reasonable costs of investigation. Notwithstanding an Indemnifying Party’s election to assume the defense of any such Action that is subject to indemnification under this ARTICLE 9, the Indemnitee will have the right to employ separate counsel and to participate in the defense of such Action, and the Indemnifying Party will bear the reasonable fees, costs and expenses of such separate counsel if: (i) the use of counsel chosen by the Indemnifying Party to represent the Indemnitee would present such counsel with a conflict of interest; or (ii) the actual or potential defendants in, or targets of, any such Action include both the Indemnifying Party and the Indemnitee, and the Indemnitee will have reasonably concluded that there may be legal defenses available to it which are different from or additional to those available to the Indemnifying Party (in which case the Indemnifying Party will not have the right to assume the defense of such Action on the Indemnitee’s behalf); or (iii) the Indemnifying Party will not have employed counsel satisfactory to the Indemnitee to represent the Indemnitee within a reasonable time after notice of the institution of such Action; or (iv) the Indemnifying Party will authorize the Indemnitee to employ separate counsel at the Indemnifying Party’s expense. If an Indemnifying Party assumes the defense of such Action, no compromise or settlement thereof may be effected by the Indemnifying Party without the Indemnitee’s written consent, which consent will not be unreasonably withheld or delayed, unless (1) there

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80(b)4, AND 240.24b-2

is no finding or admission of any violation of law or any violation of the rights of any other Party and no effect on any other claims that may be made against the Indemnitee and (2) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party.

ARTICLE 10

INTELLECTUAL PROPERTY

10.1 Patent Filing and Prosecution. Isis (at its own expense) will be responsible for preparing, filing, prosecuting, maintaining and taking such other actions as are reasonably necessary or appropriate with respect to the Product Patents. Isis will keep Lilly continuously informed of all significant matters relating to the preparation, filing, prosecution and maintenance of the Product Patents. In the event Isis proposes to abandon the prosecution or maintenance of any Product Patent, it shall notify Lilly at least [***] days in advance and allow Lilly to assume the prosecution and maintenance of such patent at Lilly’s expense.

10.2 Patent Term Extensions. The Parties will cooperate with each other in gaining patent term extension wherever applicable to any Product. The Party selling such Product will determine which patents will be extended. All filings for such extension will be made by the Party to whom the patent is assigned; provided, however, that in the event that the Party to whom the patent is assigned elects not to file for an extension, such Party will (i) inform the other Party of its intention not to file; (ii) grant the other Party the right to file for such extension; and (iii) cooperate as necessary to assist the other Party in filing such extension.

10.3 Notice of Certification. Isis and Lilly each will immediately upon receiving notice give notice to the other of any certification filed under the U.S. “Drug Price Competition and Patent Term Restoration Act of 1984” claiming that (a) Product Patent Covering the Product, is invalid or that any infringement will not arise from the manufacture, use, sale, offer for sale or import of any product by a Third Party.

10.4 Notice of Infringement Claim. If the development or commercialization of a Product under this Agreement results in a claim against a Party for patent infringement or for inducing or contributing to patent infringement (“Infringement Claim”), the Party first having notice of an Infringement Claim will promptly notify the other in writing. The notice will set forth the facts of the Infringement Claim in reasonable detail.

10.5 Responsibilities. Isis will have the sole right to control any defense of any Infringement Claim involving alleged infringement of Third Party rights by Isis’ activities at its own expense and by counsel of its own choice, and Lilly will have the right, at its own expense, to be represented in any such action by counsel of its own choice. Lilly will have the sole right to control any defense of any Infringement Claim involving alleged infringement of Third Party rights by Lilly’s activities at its own expense and by counsel of its own choice, and Isis will have the right, at its own expense, to be represented in any such action by counsel of its own choice. Notwithstanding the foregoing, if the claim involves an allegation of a violation of the trade secret rights of a Third Party, the Party accused of such

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80(b)4, AND 240.24b-2

violation will have the obligation to defend against such claim and will indemnify the other Party against all costs associated with such claim in accordance with Sections 9.5 through 9.7, as applicable. Lilly will not settle any patent infringement litigation under this Section 10.5 relating to any Product Patents without Isis’ consent. Isis will not settle any patent infringement litigation under this Section 10.5 relating to any Product Patents without Lilly’s consent, if such settlement would materially impair the rights granted to Lilly under Section 5.1, or would impose an obligation on Lilly. Each Party will also keep the other Party continually informed of all significant matters relating to Infringement Claims of Third Parties.

10.6 Infringement Claims Against Third Parties.

10.6.1 Notice of Infringement. If any Product Patent is infringed or misappropriated, as the case may be, by a Third Party, the Party to this Agreement first having knowledge of such infringement or misappropriation, will promptly notify the other in writing. The notice will set forth the facts of such infringement or misappropriation in reasonable detail. Isis will have the primary right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to infringement or misappropriation of such Product Patent by its own counsel. Lilly will have the right, at its own expense, to be represented in such action by its own counsel. Except as otherwise agreed to by the Parties in writing as part of a cost-sharing arrangement, any recovery realized as a result of such litigation, after reimbursement of any litigation expenses of Lilly and Isis, will be retained by Isis, except that any recovery realized by Isis as a result of such litigation, after reimbursement of the Parties’ litigation expenses, will, to the extent attributable to [***] or be treated as [***] of Products by Isis.

10.6.2 Expenses of Bringing Infringement Action. Isis will bear the costs and expenses of all infringement or misappropriation actions asserted against a Third Party on Product Patents.

CONFIDENTIAL TREATMENT REQUESTED

UNDER 17 C.F.R. §§ 200.80(b)4, AND 240.24b-2

The Parties agree that, during the term of this Agreement, the Parties, as licensees of such rights under this Agreement, will retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code.

11.4 Effect of Termination Due to Isis Breach or Insolvency. If Lilly terminates the Agreement based on material breach by or insolvency of Isis, then:

11.4.1 Solely in the event Isis materially breaches its obligation under [***] (or termination by Lilly under Section 11.3 before Isis has met its obligation under [***]), the option granted by Isis to Lilly pursuant to ARTICLE 5 prior to such termination, will survive, but the [***] and the amount of each [***] that would otherwise be payable under

11.6 Accrued Rights/Surviving Obligations. Except as expressly provided in this Agreement, expiration or termination of this Agreement will not relieve the Parties of any obligation that accrued prior to such expiration or termination, and Isis will be obligated to pay and will pay to Lilly, within [***] days of such expiration or termination, all payments and royalties due or accrued pursuant to the terms of ARTICLE 7.

C. Isis and Lilly are parties to the Drug Development and License Option Agreement dated December 2, 2009 (the “License Option Agreement”) pursuant to which Isis granted Lilly the option to acquire the Product;

D. On (the “Option Exercise Date”) Lilly exercised its option under the License Option Agreement; and

▇. ▇▇▇▇▇ wishes to obtain, and Isis wishes to grant, an exclusive license to enable Lilly to develop and commercialize the Product on its own.

AGREEMENT

NOW, THEREFORE, in consideration of the mutual covenants contained in this Agreement, the Parties agree as follows:

ARTICLE 1

DEFINITIONS; OPTION AGREEMENT TERMINATED

1.2 Termination of Option Agreement. The License Option Agreement is hereby terminated and replaced by this Agreement in its entirety. For purposes of clarification, such termination and replacement will not negate the effect of Section 2.1 of the License Option Agreement.

ARTICLE 2

PRODUCT DEVELOPMENT AND COMMERCIALIZTION

2.1 Development and Commercialization. As soon as practicable after the Effective Date, the parties will mutually agree upon and implement a commercially reasonable transition plan pursuant to which further development and commercialization activities will be transitioned from Isis to Lilly. The transition plan will provide for transfer to Lilly of relevant data and records, ownership of regulatory filings, and transition of Third Party arrangements (e.g., manufacturing, CRO and similar agreements), and a process for sharing class specific safety data related to the Product. Isis will not be entitled to any compensation or reimbursement for the costs of the first [***] hours of its personnel incurred in transitioning activities to Lilly. Lilly will reimburse Isis for its reasonable direct Third Party costs incurred in connection with transition activities. If Isis and Lilly agree that Isis will continue some of the development of the Product, Isis and Lilly will agree upon a plan and budget to reimburse Isis for such development activities. Following transition of activities to ▇▇▇▇▇, ▇▇▇▇▇ will be solely responsible for all development and commercialization of the Product, including toxicology, clinical development (including taking over and becoming the IND sponsor of all clinical trials that are ongoing as of the Effective Date), regulatory, manufacturing and commercialization efforts, except as agreed otherwise by the Parties. Lilly and its Sublicensees will have the sole right and responsibility for the preparation of any regulatory filings required in order to conduct clinical trials on Product in the Territory, together with the preparation of suitable applications for marketing approval in the Territory and will be the owner and party of record of all such regulatory filings. Isis will cooperate with Lilly, at Lilly’s expense, as Lilly reasonably requires in preparing such regulatory filings including, without limitation, any and all data contained therein.

ARTICLE 3

PRODUCT LICENSE

3.1 Grant of License. Subject to the terms and conditions of this Agreement, Isis hereby grants to Lilly an exclusive, royalty-bearing license, including the right to sublicense, under the Isis Technology solely to develop, make, use, import, offer for sale and sell Products in the Territory.

3.2 Diligence and Reporting. In order to maintain the license granted to Lilly under Section 3.1 above, Lilly must maintain an Active Program on the Product, and as long as Lilly has an Active Program on the Product Isis will not conduct any research on its own or with a Third Party on eIF-4E or any ASO Compound directed to eIF-4E. In the event that there is a material, uncured breach of the foregoing diligence obligation by Lilly with respect to the Product, Isis may terminate this Agreement for Lilly breach pursuant to Section 8.5. Lilly will provide Isis with annual written reports that include a description of the research, development and commercialization activities by Lilly on the Product. Lilly will provide prompt written

Within [***] months of such notice from Lilly, or within [***] months of termination of this Agreement by Isis pursuant to this Section 3.2 or Section 8.2, Isis will provide written notice to Lilly if it desires to develop a Product and whether it desires to receive from Lilly summary reports on completed IND-enabling toxicology studies and completed clinical trials for the Product. Lilly will provide such summary reports promptly after receiving such notice from Isis. If Isis fails to provide such notice within such [***] month period Lilly will have no obligation to provide such summary reports to Isis. For purposes of clarity, if Isis fails to request such summary reports from Lilly for a Product as described above in this Section 3.2, Isis may still develop a Product.

4.6 Access to Third Party Rights.

4.6.1 Third Party Licenses. If, after the Effective Date access to a Third Party’s intellectual property rights becomes necessary to make, use, import, or offer to sell, or sell a Product in the Territory, Lilly will have the right to acquire such access. [***] percent ([***]%) of the acquisition cost paid by Lilly (i.e., all consideration paid by Lilly in connection with such acquisition including, without limitation up-front payments, milestones payments and royalties) applicable to such Product will be credited against future royalties owed to Isis by Lilly under this Agreement for a Product. Except as the Parties may otherwise agree in writing, under no circumstance will Lilly acquisitions of Third Party intellectual property rights under the provisions of this Section 4.5.1 result in a reduction of Net Royalties payable to Isis under this Agreement by more than [***] ([***]%) percent of the royalty otherwise due to Isis.

4.6.2 Oral Preparation, Formulation or Delivery Technology. Any oral preparation, formulation or delivery technology that is applicable to the Product that is obtained by Isis from any Affiliate or Third Party, including [***], will be made available to Lilly, at Lilly’s discretion, for use at a cost (including royalties, milestones and other payments) that is no greater than the [***] payable by Isis to such Third Party. Any oral preparation, formulation or delivery technology developed by Isis during the term of the Agreement that is applicable to the Products will be made available to Lilly hereunder as Isis Technology.

4.6.3 Royalty Obligations. Except as otherwise provided in this Agreement both Parties acknowledge and agree that each is solely responsible for any and all royalty obligations that have accrued or may accrue in the future with respect to any agreements and/or arrangement that such Party may have agreed to prior to the Effective Date. Except as otherwise provided in this Agreement, any Third Party technology acquired by Isis that is applicable to the Product will be made available to Lilly at the cost (including royalties, milestones and other payments) payable by Isis to such Third Party.

4.7 Compulsory License. If in any country a Third Party obtains a Compulsory License to sell a Product, then Lilly or Isis, respectively, will promptly notify the other Party. If the royalty rate payable by the grantee of the Compulsory License is less than the then-current royalty rate paid under this Agreement, then the royalty rate, payable under this Agreement with respect to such Product, will be reduced to such lower rate in the subject country for so long as sales are made pursuant to the Compulsory License; provided, however, that in no event will the Net Royalty to Isis fall below [***] percent ([***]%).

4.8 Inflation. The increments of annual Net Sales tiers set forth in Sections 4.3 will be adjusted on a Calendar Year basis commencing January 1, [***] (and on January 1 of each year thereafter during the term of this Agreement) by an amount equal to the percentage change, if any, in the CPI for the preceding year.

4.9 Accounting Reports; Payment of Royalty. Lilly (including its Affiliates) and its Sublicensees will keep complete and accurate books and records which may be necessary to ascertain properly and to verify the payments owed hereunder. To the extent Lilly has prepared such information for its own purposes, if requested in writing by Isis, Lilly will provide to Isis [***] ([***]) days after the end of each Calendar Quarter a written report with Lilly’s good faith estimate of Lilly’s Net Sales accrued in the preceding Calendar Quarter and the royalties payable thereon. Lilly will make royalty payments to Isis for Products sold by Lilly, its Affiliates and Sublicensees during the Calendar Quarter within [***] ([***]) days of the last day of that Calendar Quarter. Each royalty payment will be accompanied by a written report for that Calendar Quarter showing the Net Sales of the Products sold by Lilly, its Affiliates and Sublicensees worldwide during the quarterly reporting period and the calculation of the royalties payable under this Agreement.

4.10 Audits. Upon Isis’ written request, and not more than once in each Calendar Year, Lilly will permit Lilly’s independent certified public accountant to have access during normal business hours to such of Lilly’s records as may be reasonably necessary to verify the accuracy of the royalty reports hereunder for the current year and the preceding [***] ([***]) years prior to the date of such request. Isis will submit an audit plan, including audit scope, to Lilly for Lilly’s approval, which will not be unreasonably withheld, prior to audit implementation. The independent certified public accountants will keep confidential any information obtained during such inspection and will report to Isis only the amounts of Net Sales and royalties due and payable. Upon the expiration of [***] ([***]) years following the end of any Calendar Year, the calculation of royalties payable with respect to such year will be binding and conclusive upon Isis, and Lilly and its Affiliates and Sublicensees will be released from any liability or accountability with respect to royalties for such year. If such accounting firm concludes that additional royalties were owed, or that Lilly overpaid royalties, during such period, Lilly will pay the additional royalties, or Isis will return any overpaid royalties, within [***] ([***]) days of the date Isis delivers to Lilly such accounting firm’s written report. The fees charged by such accounting firm will be paid by Lilly unless the additional royalties owed by Lilly exceed [***] percent ([***]%) of the royalties paid for the royalty period subject to the audit, in which case Lilly will pay the reasonable fees of the accounting firm. Lilly will include in each sublicense granted by it pursuant to this Agreement a provision requiring the Sublicensee to make reports to Lilly, to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records by a mutually agreed upon independent accountant to the

same extent required of Lilly under this Agreement. Lilly will treat all financial information subject to review under this Section 4.10 or under any sublicense agreement in accordance with the confidentiality provisions of this Agreement, and will cause its accounting firm to enter into an acceptable confidentiality agreement with Lilly obligating it to retain all such financial information in confidence pursuant to such confidentiality agreement.

4.11 Payment. All payments to Isis under this Agreement will be made in United States Dollars by bank wire transfer in next day available funds to such bank account in the United States designated in writing by Isis from time to time. Lilly will pay a late payment service charge of [***]% per month (or the highest amount allowed by law, if lower than [***]%) on all past-due amounts owed by such Party under this Agreement.

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER PARTY MAKES ANY REPRESENTATION OR WARRANTY TO THE OTHER PARTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Without limiting the generality of the foregoing, each Party expressly does not warrant (a) the success of any Product or (b) the safety for any purpose of the technology it provides hereunder.

6.5 Isis’ Right to Indemnification. Lilly will indemnify each of Isis, its Affiliates, Sublicensees, permitted successors and assigns, and the directors, officers, employees, agents and counsel thereof (the “Isis Indemnitees”), and defend and hold each Isis Indemnitee harmless from and against any and all liabilities, damages, losses, settlements, claims, actions, suits, penalties, fines, costs or expenses (including, without limitation reasonable attorneys’ fees) (any of the foregoing, “Damages”) incurred by or asserted against any Isis Indemnitee of whatever kind or nature, including, without limitation, any claim or liability based upon negligence, warranty, strict liability, or violation of government regulation but only to the extent arising from or occurring as a result of a claim or demand made by a Third Party (a “Third Party Claim”) against any Isis Indemnitee arising because of: (a) breach of any representation or warranty made by Lilly pursuant to this ARTICLE 6; (b) any material breach of this Agreement by Lilly; (c) the manufacture, use, handling, storage, sale or other disposition of a Product that is

sold or provided by Lilly, its Affiliates, agents or Sublicensees; and/or (d) violation of the trade secrets of any Third Party by Lilly; except, in each such case in subparagraphs (a) through (d) above, to the extent that such Damages are finally determined to have resulted from the negligence or misconduct of an Isis Indemnitee, or the breach of any representation or warranty under Section 6.1 by Isis.

6.6 Lilly’s Right to Indemnification. Isis will indemnify each of Lilly, its Affiliates, Sublicensees, successors and assigns, and the directors, officers, employees, agents and counsel thereof (the “Lilly Indemnitees”), and defend and hold each Lilly Indemnitee harmless from and against any and all Damages incurred by or asserted against any Lilly Indemnitee of whatever kind or nature, including, without limitation, any claim or liability based upon negligence, warranty, strict liability, violation of government regulation but only to the extent arising from or occurring as a result of a Third Party Claim against any Lilly Indemnitee arising because of: (a) breach of any representation or warranty made by Isis pursuant to this ARTICLE 6; (b) any material breach of this Agreement by Isis; (c) the manufacture, use, handling, storage, sale or other disposition of a Product that is sold or provided by Isis, its Affiliates, agents or Sublicensees; (d) violation of the trade secrets of any Third Party by Isis and/or (e) any Third Party Claim that any Isis Technology should not have been disclosed or made available to Lilly; except, in each such case, in subparagraphs (a) through (e) above, to the extent that such Damages are finally determined to have resulted from the negligence or misconduct of a Lilly Indemnitee, or the breach of any representation or warranty under Section 6.2 by Lilly.

6.7 Indemnification Procedures. Promptly after a Party entitled to indemnification under Section 6.5 or 6.6 (an “Indemnitee”) receives notice of any pending or threatened claim against it (an “Action”), such Indemnitee will give written notice to the Party to whom the Indemnitee is entitled to look for indemnification pursuant to Section 6.5 or 6.6, as applicable (the “Indemnifying Party”), of the commencement thereof, provided that the failure so to notify the Indemnifying Party will not relieve it of any liability that it may have to any Indemnitee hereunder, except to the extent the Indemnifying Party demonstrates that it is prejudiced thereby. In case any Action that is subject to indemnification under this ARTICLE 6, will be brought against an Indemnitee and it will give written notice to the Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to participate therein and, if it so desires, to assume the defense thereof with counsel reasonably satisfactory to such Indemnitee and, after notice from the Indemnifying Party to the Indemnitee of its election to assume the defense thereof, the Indemnifying Party will not be liable to such Indemnitee under this ARTICLE 6 for any fees of other counsel or any other expenses, in each case subsequently incurred by such Indemnitee in connection with the defense thereof, other than reasonable costs of investigation. Notwithstanding an Indemnifying Party’s election to assume the defense of any such Action that is subject to indemnification under this ARTICLE 6, the Indemnitee will have the right to employ separate counsel and to participate in the defense of such Action, and the Indemnifying Party will bear the reasonable fees, costs and expenses of such separate counsel if: (i) the use of counsel chosen by the Indemnifying Party to represent the Indemnitee would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such Action include both the Indemnifying Party and the Indemnitee, and the Indemnitee will have reasonably concluded that there may be legal defenses available to it which are different from or additional to those available to the Indemnifying Party (in which case the

Indemnifying Party will not have the right to assume the defense of such Action on the Indemnitee’s behalf); (iii) the Indemnifying Party will not have employed counsel satisfactory to the Indemnitee to represent the Indemnitee within a reasonable time after notice of the institution of such Action; or (iv) the Indemnifying Party will authorize the Indemnitee to employ separate counsel at the Indemnifying Party’s expense. If an Indemnifying Party assumes the defense of such Action, no compromise or settlement thereof may be effected by the Indemnifying Party without the Indemnitee’s written consent, which consent will not be unreasonably withheld or delayed, unless (1) there is no finding or admission of any violation of law or any violation of the rights of any other Party and no effect on any other claims that may be made against the Indemnitee and (2) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party.

ARTICLE 7

INTELLECTUAL PROPERTY

7.1 Patent Filing and Prosecution. Except as provided in Section 7.2, Isis will be responsible for preparing, filing, prosecuting, maintaining and taking such other actions as are reasonably necessary or appropriate with respect to the Isis Patent Rights.

7.2 Lilly at its own expense, will prepare, file, prosecute and/or maintain the Isis ASO Compound Patent Rights that are exclusively licensed by Lilly pursuant to Section 3.1. In the event of termination under Section 3.2 or 8.5, or upon written agreement of the Parties, such responsibility and expense for preparation, filing, prosecuting and maintenance will revert back to Isis. Lilly may use in-house patent counsel or outside patent counsel that is acceptable to Isis for the filing, prosecution and maintenance of Isis ASO Compound Patent Rights for which Lilly assumes responsibility for under this Section 7.2. Isis will promptly transfer the subject patent files to Lilly and will execute such documents and perform such acts as may be reasonably necessary for Lilly to take control of such patent filing, prosecution and maintenance and will provide all necessary assistance in the prosecution and maintenance thereof. Lilly will, in a timely manner, provide Isis with copies of all draft applications, responses and other substantive papers relating to the filing, prosecution and maintenance (including the verification of all fees and annuities) of such Isis ASO Compound Patent Rights and will provide Isis with an opportunity to comment on any draft applications, responses or amendments at least [***] days prior to filing and to the extent practicable incorporate such comments. Isis hereby acknowledges a possible conflict of interest between Lilly and Isis relating to the Isis ASO Compound Patent Rights for which Lilly assumes responsibility for filing, prosecution and maintenance under this Section 7.2. So long as Lilly complies with provisions of this Section 7.2, Isis hereby grants Lilly and Lilly’s patent counsel a conflict waiver, to the limited extent of any conflict of interest arising from the fact that (a) Lilly has the right to prepare, file, prosecute and maintain the Isis ASO Compound Patent Rights pursuant to this Section 7.2 and (b) Isis owns or Controls such Patent Rights. Isis and Lilly will discuss in good faith assignment of any ASO Compound Patent Rights to Lilly.

7.3 Election Not to File, Prosecute or Maintain. If Lilly elects to discontinue prosecution or maintenance of any Isis ASO Compound Patent Right for which Lilly assumes responsibility for filing, prosecution and maintenance (or that is assigned to Lilly) under Section

7.2, then Lilly will give [***] days advance written notice to Isis of any decision to cease preparation, filing, prosecution and maintenance of that Patent Right (a “Discontinued Patent”); provided, however, that abandonment of a patent application in favor of a continuation or a continuation-in-part thereof will not constitute discontinuance of the patent application. In such case, Isis may elect at its sole discretion to continue preparation, filing, prosecution or maintenance of the Discontinued Patent at its sole expense, and Isis will own any such patent application and patents maturing therefrom and be solely responsible for all costs, and Lilly will have a non-exclusive, worldwide, royalty-bearing (under Section 4.3) license to continue to practice such Discontinued Patent, including the right to sublicense solely to develop, make, use, import, offer for sale and sell a Product, in accordance with the terms of Section 3.1. Lilly will execute such documents and perform such acts as may be reasonably necessary for Isis to file or to continue prosecution or maintenance, including assigning ownership of such patents and inventions to Isis. Discontinuance may be on a country-by-country basis or for a patent application or patent series in total.

7.4 Costs and Expenses. Lilly will bear its own costs and expenses in filing, prosecuting, maintaining and extending the Isis ASO Patent Rights. Isis will bear its own costs and expenses in filing, prosecuting, maintaining and extending the Isis Core Technology Patent Rights and the Isis Manufacturing Patent Rights.

7.5 Patent Term Extensions. The Parties will cooperate with each other in gaining patent term extension wherever applicable to any Product. The Party selling such Product will determine which patents will be extended. All filings for such extension will be made by the Party selling such Product; provided, however, that in the event that the Party to selling such Product elects not to file for an extension, such Party will (i) inform the other Party of its intention not to file, (ii) grant the other Party the right to file for such extension, and (iii) cooperate as necessary to assist the other Party in filing such extension.

7.6 Notice of Certification. Isis and Lilly each will immediately upon receiving notice give notice to the other of any certification filed under the U.S. “Drug Price Competition and Patent Term Restoration Act of 1984” claiming that an Isis Patent Right Covering a Product being developed or commercialized by Lilly hereunder is invalid or that any infringement will not arise from the manufacture, use, sale, offer for sale or import of any product by a Third Party. If permitted under Section 7.2 and Lilly decides not to bring infringement proceedings against the entity making such a certification with respect to a Isis Patent Right Covering a Product being developed or commercialized by Lilly hereunder, Lilly will give notice to Isis of its decision not to bring suit within twenty-one (21) days after receipt of notice of such certification. Isis may then, but is not required to, bring suit against the entity that filed the certification. Any suit by Lilly or Isis will either be in the name of Lilly or in the name of Isis, or jointly by Lilly and Isis, as may be required by law. For this purpose, the Party not bringing suit will execute such legal papers necessary for the prosecution of such suit as may be reasonably requested by the Party bringing suit. Any costs incurred or benefits received as a result of proceeding under this Section 7.6 will be paid or received entirely by the Party who pursued the action.

7.7 Notice of Infringement Claim. If the practice of a license granted to a Party under this Agreement results in a claim against a Party for patent infringement or for inducing or contributing to patent infringement (“Infringement Claim”), the Party first having notice of an

Infringement Claim will promptly notify the other in writing. The notice will set forth the facts of the Infringement Claim in reasonable detail.

7.8 Responsibilities. Isis will have the sole right to control any defense of any Infringement Claim involving alleged infringement of Third Party rights by Isis’ activities at its own expense and by counsel of its own choice, and Lilly will have the right, at its own expense, to be represented in any such action by counsel of its own choice. Lilly will have the sole right to control any defense of any Infringement Claim involving alleged infringement of Third Party rights by Lilly’s activities at its own expense and by counsel of its own choice, and Isis will have the right, at its own expense, to be represented in any such action by counsel of its own choice. Notwithstanding the foregoing, if the claim involves an allegation of a violation of the trade secret rights of a Third Party, the Party accused of such violation will have the obligation to defend against such claim and will indemnify the other Party against all costs associated with such claim (in accordance with Sections 6.5 through 6.7). Neither Party will have the right to settle any patent infringement litigation under this Section 7.8 relating to any Patent Rights owned by or exclusively licensed to the other Party hereunder without the consent of such other Party. Each Party will also keep the other Party continually informed of all significant matters relating to Infringement Claims of Third Parties.

7.9 Infringement Claims Against Third Parties.

7.9.1 Protection Against Infringement. Isis and Lilly each agree to take reasonable actions to protect their respective patents and technology from infringement and from unauthorized possession or use.

7.9.2 Notice of Infringement. If any Isis ASO Compound Patent Right licensed by Isis to Lilly under this Agreement is infringed or misappropriated, as the case may be, by a Third Party, the Party to this Agreement first having knowledge of such infringement or misappropriation, will promptly notify the other in writing. The notice will set forth the facts of such infringement or misappropriation in reasonable detail. In such case, Lilly will have the primary right, but not the obligation, to institute, prosecute, and control any action or proceeding with respect to infringement or misappropriation of such Isis ASO Compound Patent Right by its own counsel. The other Party will have the right, at its own expense, to be represented in such action by its own counsel. Except as otherwise agreed to by the Parties as part of a cost-sharing arrangement, any recovery realized as a result of such litigation, after reimbursement of any litigation expenses of Isis and Lilly, will be retained by the Party that brought and controlled such litigation for purposes of this Agreement, except that any recovery realized by Lilly as a result of such litigation, after reimbursement of the Parties’ litigation expenses, will, to the extent [***] to [***], be treated as [***] of [***] by Lilly.

7.9.3 Expenses of Bringing Infringement Action. Subject to Section 7.9.2, Lilly will bear the costs and expenses of all infringement or misappropriation actions brought by Lilly under this Agreement. Subject to Section 7.9.2, Isis will bear the costs and expenses of all infringement or misappropriation actions brought by Isis under this Agreement.

7.9.4 Lilly’s Failure to Institute, Prosecute and Control. If Lilly fails to institute, prosecute, and control such action or prosecution within a period of [***] days after

receiving notice of the infringement, Isis, subject to the prior rights of any Third Party, will have the right to bring and control any such action by counsel of its own choice, and Lilly will have the right, at its own expense, to be represented in any such action by counsel of its own choice. Except as otherwise agreed to by the Parties as part of a cost-sharing arrangement, any recovery realized as a result of such litigation, after reimbursement of 100% of any litigation expenses of Isis and 100% of any litigation expenses of Lilly (including the costs and expenses incurred by Lilly in providing reasonable assistance to Isis), will be shared [***] by the Parties. No settlement or consent judgment or other voluntary final disposition of a suit under this Section 7.9.4 may be entered into without the joint consent of Isis and Lilly (which consent will not be unreasonably withheld or delayed).

7.9.5 Settlement Approval. Neither Party will settle any such proceeding under this Section 7.9 without the approval of the other Party, which approval will not be unreasonably withheld or delayed.

ARTICLE 8

TERM AND TERMINATION

8.1 Term of Agreement. This Agreement will commence on the Effective Date and will continue until no payments are due or are capable of becoming due hereunder, unless the Agreement is terminated earlier in accordance with this ARTICLE 8. All licenses granted hereunder that are in effect at expiration of this Agreement will be deemed fully paid-up and perpetual (as more specifically described in 8.6.1 below), except as provided otherwise by this Agreement.

8.2 Termination for Breach. Either Party may terminate this Agreement by notice to the other Party at any time during the term of this Agreement if the other Party is in breach of any material obligations hereunder and has not cured such breach within ninety (90) days after notice requesting cure of the breach or such longer period of time as is required to cure such breach as long as the breaching Party is proceeding in good faith to cure; provided, however, that in any case when a breach is alleged regarding the payment of money hereunder, the time period will be thirty (30) days and undisputed amounts must be paid prior to such time to avoid breach. Upon material breach by a Party of its obligations hereunder, if such Party decides not to terminate this Agreement, such Party will have the right to offset any costs it may incur as a result of curing such breach against the amounts payable to the breaching Party for the performance of such obligations. Further, to the extent that a Party prevails in a lawsuit brought against the other Party for material breach of this Agreement, such prevailing Party will be entitled to collect from the other Party reasonable attorneys’ fees and legal costs incurred in connection with such law suit. If the non-breaching Party terminates this Agreement under Section 8.2 following material breach by the breaching Party, the breaching Party will return to the non-Breaching Party all of the non-breaching Party’s Confidential Information and all materials received from the non-breaching Party during the Agreement, and the breaching Party will cease all use of the non-breaching Party’s Confidential Information and materials received from the non-breaching Party for any purpose except as provided in Section 8.7, and except that the breaching Party may (1) keep a copy of all documents for record keeping purposes only and (2) keep and use any Confidential Information and materials received from the non-breaching

Party that are necessary for the breaching Party to exercise those of its rights and fulfill those of its obligations that survive the termination of this Agreement.

8.3 Termination Upon Insolvency. Either Party may terminate this Agreement upon notice to the other should the other Party become insolvent or file or consent to the filing of a petition under any bankruptcy or insolvency law or have any such petition filed against it which has not been stayed within sixty (60) days of such filing. During the term of this Agreement, all rights and licenses granted under or pursuant to this Agreement by Isis or Lilly are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that, during the term of this Agreement, the Parties, as licensees of such rights under this Agreement, will retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding-by or against either Party under the U.S. Bankruptcy Code, the Party hereto that is not a party to such proceeding will be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, and same, if not already in their possession, will be promptly delivered to them (i) upon any such commencement of a bankruptcy proceeding upon their written request therefor, unless the Party subject to such proceeding elects to continue to perform all of its obligations under this Agreement, or (ii) if not delivered under (i) above, following the rejection of this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by the non-subject Party.

8.4 Termination at Will by Lilly. Lilly shall have the right to terminate this Agreement at will upon 90 days written notice to Isis.

8.5 Effect of Termination Due to Lilly Breach, Insolvency or at Will. If Isis terminates the Agreement based on material breach by or insolvency of Lilly, or if Lilly terminates this agreement at will pursuant to Section 8.4, then:

8.5.1 the licenses granted by Isis to Lilly pursuant to Section 3.1 will terminate, and Lilly will stop making and selling such Product;

8.5.2 any sublicense granted by either Party to any Sublicensee under a license hereunder that terminates as a result of termination of this Agreement by Isis pursuant to Section 8.2 or 8.3 will continue in full force and effect but will be assigned by such Party to the other Party, and such Party will provide the other Party with complete and accurate copies of such sublicense agreements within thirty (30) days following the effective date of such termination; and

8.5.3 Lilly will promptly re-assign any patents assigned to Lilly under this Agreement, and Lilly will assign or otherwise transfer ownership of any regulatory filings related to the Product.

8.6 Effect of Termination Due to Isis Breach or Insolvency. If Lilly terminates the Agreement based on material breach by or insolvency of Isis, then:

8.6.1 licenses granted by Isis to Lilly pursuant to Section 3.1 will survive;

8.6.2 Lilly’s payment obligations set forth in ARTICLE 4 will continue, provided, however, that the amounts of the payments will be decreased to reflect the nature of Isis’s breach and the damages caused thereby by amounts to be agreed upon by the Parties or, if the Parties are unable to reach agreement, by an independent Third Party with the requisite expertise selected by the Parties, the expense of which will be borne by Isis; and

8.6.3 any sublicense granted by either Party to any Sublicensee under a license hereunder that terminates as a result of termination of this Agreement by Lilly pursuant to Section 8.2 or 8.3 will continue in full force and effect but will be assigned by such Party to the other Party, and such Party will provide the other Party with complete and accurate copies of such sublicense agreements within thirty (30) days following the effective date of such termination.

8.7 Accrued Rights/Surviving Obligations. Except as expressly provided in this Agreement, expiration or termination of this Agreement will not relieve the Parties of any obligation that accrued prior to such expiration or termination, and Lilly will be obligated to pay and will pay to Isis, within [***] days of such expiration or termination, all payments and royalties due or accrued pursuant to the terms of ARTICLE 4. Upon expiration or early termination of this Agreement, all rights and obligations of the Parties will cease, except as follows:

8.7.1 In the case of expiration of this Agreement only (and, for purposes of clarification, not in the case of termination of this Agreement pursuant to Section 8.2 or 8.3), each of the licenses set forth in Sections 3.1 will survive and will be deemed to be perpetual and fully paid up, provided that all payment and other obligations with respect to such licenses have been fulfilled;

8.7.2 The obligations to pay royalties and other sums accruing hereunder up to the date of termination or expiration will survive;

8.7.3 The obligations of confidentiality set forth in ARTICLE 5 will survive;

8.7.4 The obligations for record keeping and accounting reports set forth in ARTICLE 4 will survive for so long as Products are sold. At such time after termination or expiration of this Agreement when sales or other dispositions of Products have ceased, the Party selling such Product will render a final report along with any royalty payment due;

8.7.5 Isis’ and Lilly’s rights to inspect books and records as described in ARTICLE 4 will survive;

8.7.6 The obligations of defense and indemnity set forth in ARTICLE 6 will survive;

8.8 Limitation of Liability. No Party will be liable to another for indirect, incidental, consequential or special damages, including but not limited to lost profits, arising from or relating to any breach of this Agreement, regardless of any notice of the possibility of such damages. Nothing in this Section is intended to limit or restrict the indemnification rights or obligations of any Party under ARTICLE 6.

ARTICLE 9

9.1 Press Release. Upon execution of this Agreement, the Parties shall issue a joint press release announcing the existence of this Agreement in a form and substance agreed to in writing by the Parties.

9.2 Disclosure of Agreement. Neither Party to this Agreement may release any information to any Third Party regarding the terms or existence of this Agreement or the reasons for any termination hereof, without the prior written consent of the other Party. Without limitation, this prohibition applies to press releases, educational and scientific conferences, quarterly investor updates, promotional materials, governmental filings and discussions with public officials, the media, security analysts and investors.
