Article 2.
LICENSES

2.1. Product License. Isis hereby grants to Genzyme an exclusive license, with the limited right to sublicense as set forth in Section 2.2 (Limited Right to Sublicense), under the Licensed IP to research, develop, make, have made, use, sell, offer for sale, have sold, import and export Products in the Territory for therapeutic purposes. Notwithstanding the foregoing, (a) the exclusive license to the Isis Core Technology Patents will be subject to the licenses granted by Isis to Third Parties identified on Schedule 2.1 and Isis’ right to grant Permitted Licenses and (b) with respect to any Follow-On Compound, the provisions of Section 2.4 (Follow-On Compound) will govern the extent to which In-Licensed Third Party IP is included within Licensed IP.

2.2. Limited Right to Sublicense.

2.2.1. The Product License is sublicensable only in connection with a sublicense of a Product to any Affiliate of Genzyme or to any Third Party, in each case for the continued research, development or commercialization of such Product in accordance with the terms of the Product License.

2.2.2. Notwithstanding the foregoing, the licenses granted to Genzyme under the Isis Manufacturing and Analytical IP are sublicensable to a Third Party [**] only in accordance with Section 6.3.1 (Manufacture).

2.3. Additional Rights after Prior Agreement Execution Date. After the Prior Agreement Execution Date, Isis may wish to in-license or acquire rights to Know-How or Patents Controlled by Third Parties (such a Third Party in-license or acquisition agreement being an “Additional Third Party Agreement”) which, if so licensed or acquired, may be included in the Licensed IP licensed to Genzyme under Section 2.1. In such event (and to the extent permitted by Isis’ confidentiality agreement with the applicable Third Party), Isis will notify Genzyme regarding the nature of the technology and status of negotiations related to the Additional Third Party Agreement through the JDC. Once Isis has executed such Additional Third Party Agreement, Isis will offer such Third Party Patents or Know-How to Genzyme (which offer will include a description of the payments paid or potentially payable by Isis thereunder). At such time, if Genzyme wishes to include such Third Party Patents or Know-How under the license granted under Section 2.1, Genzyme will notify Isis of its desire to do so and the Parties will fairly and in good faith allocate upfront payments or ongoing payment obligations between Products and compounds that are not Products, if any, and other Isis licensees, if appropriate. As part of this allocation process, Isis will share with Genzyme, in reasonable detail, the assumptions and methodology Isis used to create the proposed allocation. If Genzyme does not agree to reimburse Isis for the amount of any upfront or similar acquisition payments fairly allocated to Product, and to be responsible for the payment of its share of any upfront, milestone, and royalty payments, then the Know-How or Patents acquired or in licensed by Isis under the Additional Third Party Agreement will not be considered Licensed IP licensed to Genzyme under the Product License. When Genzyme pays its share of any upfront, milestone, and royalty payments assumed by Genzyme under this Section 2.3, such payments will be considered Program Costs for the applicable Product. Except for Patents acquired by Isis as part of an acquisition of a Third Party’s business,

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

before Isis in-licenses or acquire rights to any Patent Controlled by Third Parties which, if acquired, would be a Product-Specific Patent, Isis will first notify Genzyme in writing and allow Genzyme to license or acquire such Patent on the terms offered Isis. If Genzyme informs Isis that Genzyme is not interested in licensing or acquiring such Patent or does not license or acquire such Patent within 180 days of Isis’ notice to Genzyme, then Isis will be free to in-license or acquire such Patent.

2.4. Follow-On Compound. The Parties contemplate that after the Effective Date Genzyme, either on its own or in collaboration with Isis, may wish to research, develop, and commercialize Follow-On Compounds. The scope of the In-Licensed Third Party IP included in Licensed IP under the Product License with respect to such Follow-On Compounds will be determined in accordance with the procedures set forth in this Section 2.4. At the time Genzyme intends to designate a Follow-On Compound as a development candidate, Genzyme will notify Isis in writing of such intention and will describe in reasonable detail the applicable Follow-On Compound. Subject to Section 2.3 (Additional Rights after Prior Agreement Execution Date), if a Follow-On Compound utilizes any In-Licensed Third Party IP (an “Encumbered Follow-On Compound”), such In-Licensed Third Party IP will be included in Licensed IP only to the extent set forth below:

2.4.1. If the applicable Third Party Agreement contains a contractual obligation that would preclude Isis from including such In-Licensed Third Party IP in Licensed IP with respect to such Encumbered Follow-On Compound, then the In-Licensed Third Party IP that is the subject of such Third Party Agreement will not be included in Licensed IP.

2.4.2. If the applicable Third Party Agreement contains any potential encumbrances known by Isis and related to the potential Follow-On Compound, including field or territory restrictions, covenants, or milestones, royalty, sublicense revenue, or other payments (“Follow-On Compound Encumbrances”), Isis will fully disclose to Genzyme such Follow-On Compound Encumbrances and, if Genzyme agrees in writing to assume the Follow-On Compound Encumbrances (with any payments being included in Program Costs for such Encumbered Follow-On Compound), then the In-Licensed Third Party IP that is the subject of such Third Party Agreement will be included in Licensed IP.

2.4.3. If the applicable Third Party Agreement does not contain the obligations or encumbrances described in Sections 2.4.1 and 2.4.2 above, the In-Licensed Third Party IP that is the subject of such Third Party Agreement will automatically be included in Licensed IP.

2.4.4. If the applicable Third Party Agreement is or was also applicable to Mipomersen, then the In-Licensed Third Party IP that is the subject of such Third Party Agreement will automatically be included in the Licensed IP to the extent that (a) the terms of such Third Party Agreement do not preclude Isis from including it and (b) Genzyme agrees in writing to assume any applicable Follow-On

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

Compound Encumbrances associated with such Third Party Agreement.

2.4.5. Each time the Parties complete the process set forth above, Isis will update the schedules relating to Licensed Patents and Third Party Agreements, and Schedule 2.1 as appropriate.

2.5. Retained Rights. Subject to the terms and conditions of this Agreement, Isis retains the non-exclusive, non-transferable, non-licensable right under the Licensed IP only to the extent necessary for Isis to perform its obligations under this Agreement and the Supply Agreement.

2.6. Isis’ Right of First Negotiation. With respect to any Genzyme Program IP that would be relevant to antisense therapies as a whole, including but not limited to, manufacturing, formulation and delivery technologies or oligonucleotide chemical modifications or the design of antisense therapeutics generally, then Genzyme hereby grants to Isis a right of first negotiation with respect to any exclusive license that Genzyme may elect to grant under such Genzyme Program IP (each, an “Antisense License”) on the following terms and conditions:

2.6.1. General. Genzyme will not grant an Antisense License to any Third Party (or enter into discussions with, or solicit interest from, any Third Party regarding an Antisense License) unless and until:

(a) Genzyme gives written notice (the “Antisense License Notice”) to Isis of Genzyme’s interest in granting an Antisense License, which notice will identify in reasonable detail the proposed scope and terms and conditions of the license Genzyme proposes to grant; and

(b) (i) Isis notifies Genzyme that it declines the opportunity to negotiate with Genzyme regarding such a license, (ii) Isis does not indicate to Genzyme a desire to proceed with negotiations within forty-five (45) days after receipt of the Antisense License Notice, or (iii) Genzyme is otherwise permitted to enter into an Antisense License with a Third Party pursuant to Section 2.6.3 (Look Back).

2.6.2. Negotiation Period. If Isis notifies Genzyme, within forty-five (45) days after receipt of the Antisense License Notice, that it desires the opportunity to negotiate with Genzyme regarding such an Antisense License, the Parties will negotiate exclusively with each other for ninety (90) days (or such longer period as mutually agreed by the Parties) (the “Exclusive Negotiation Period”) and will use commercially reasonable efforts to reach agreement regarding a mutually satisfactory Antisense License on commercially reasonable terms. During the Exclusive Negotiation Period, Genzyme will not enter into negotiations regarding an Antisense License with any Third Party.

2.6.3. Look Back. In the event that the Exclusive Negotiation Period expires before Genzyme and Isis have entered into an Antisense License, Genzyme will have no further obligation to negotiate with Isis with respect to any Antisense License in

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

any country in the Territory, and Genzyme will be free to grant one or more Antisense Licenses to one or more Third Parties in any country or countries in the Territory at Genzyme’s sole discretion; provided, however, that for a period equal to the longer of (i) the Term plus one (1) year or (ii) three (3) years following the expiration of the Exclusive Negotiation Period, Genzyme will not offer any Third Party an Antisense License containing a license scope and financial terms that are more favorable to the Third Party than the license scope and financial terms that Genzyme last offered to Isis during the Negotiation Period unless Genzyme first offers an Antisense License with such more favorable scope and terms to Isis in writing and Isis fails to accept such offer within fourteen (14) days after receiving it.

2.6.4. Non-Exclusive License. If Genzyme grants any Third Party a non-exclusive license under any Genzyme Program IP that would be relevant to antisense therapies as a whole, including but not limited to, manufacturing, formulation and delivery technologies or oligonucleotide chemical modifications or the design of antisense therapeutics generally, then Genzyme will promptly notify Isis of such license and will offer Isis a non-exclusive license under such licensed Genzyme Program IP with substantially similar scope and financial terms.

2.7. Third Party Agreements.

2.7.1. Exercise of Rights. Isis will exercise its rights under the Third Party Agreements in a manner that is as consistent as possible with the terms of this Agreement and in consultation with and as reasonably requested by Genzyme. Isis covenants that it will not, without Genzyme’s prior written consent, agree, consent or acquiesce to any amendment, supplement or other modification to any Third Party Agreement or take any action under such Third Party Agreement or with respect to the intellectual property licensed thereunder that would adversely affect the rights granted to Genzyme under this Agreement, including under the Product License. Isis will immediately notify Genzyme of (a) any event that adversely affects the rights granted to Isis under a Third Party Agreement that are, in turn, sublicensed to Genzyme pursuant to this Agreement or (b) receipt by Isis of any notice of breach or termination of any Third Party Agreement. Isis will take all reasonable actions necessary, or permit Genzyme to take such actions, to maintain and enforce its rights under the Third Party Agreements in a manner that is consistent with the terms of this Agreement.

2.7.2. Sublicense Survival. Isis covenants that it will use good faith and Commercially Reasonable Efforts to enter into any necessary amendments or side agreements to its Third Party Agreements to ensure that (a) sublicenses under each Third Party Agreement will survive termination of such Third Party Agreement or (b) Genzyme will receive a direct license from the counterparty to each Third Party Agreement upon termination of such Third Party Agreement.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

2.8. No Implied License. Except as expressly provided in this Agreement, neither Party will be deemed by estoppel or implication to have granted the other Party any license or other right with respect to any intellectual property of such Party. Without limiting the generality for the foregoing, a license to use Know-How will not be interpreted as an implied license under any Patent Rights other than as expressly provided in this Agreement.

Article 3.

The JDC will remain in place for four (4) years following the Effective Date; provided, however that if the commercial launch of the Product for a non-FH indication has not occurred by the end of such 4-year period, the Parties will mutually agree upon an appropriate extension of the JDC.

4.1.2. Responsibilities of the JDC. In addition to any responsibilities expressly described elsewhere in this Agreement, the JDC will:

(a) On a Calendar Quarter basis, review and evaluate progress under the Development Plan and expenditures relative to the Development Budget;

(b) Develop updates or amendments to the Development Plan and the Development Budget;

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

(d) Review and approve a scientific and medical publication plan and medical affairs plan for the Product;

(e) Appoint one or more working group(s) to oversee particular activities to be performed under the Development Plan or create the scientific and medical publication plan and medical affairs plan for the Product, which working group(s) will dissolve no later than the date of the dissolution of the JDC.

For the avoidance of doubt, the JDC will have no authority to amend this Agreement.

4.1.3. Meetings; Minutes. During the course of implementing the Development Plan, the JDC will meet at least once each Calendar Quarter, and more frequently as the Parties mutually agree is appropriate, on such dates, in such places and at such times as the Parties will agree. The JDC will be chaired by Genzyme as of the Effective Date. The role of the chairperson will be to convene and preside at meetings of the JDC, but the chairperson will not be entitled to prevent items from being discussed or to cast any tie-breaking vote. Reasonably detailed written minutes will be kept of all JDC meetings and will reflect without limitation material decisions made at such meetings. The chairperson of the JDC will have responsibility for keeping minutes. Draft meeting minutes will be sent to each member of the JDC for review and approval within ten (10) business days after a meeting. Minutes will be deemed approved unless a member of the JDC objects to the accuracy or completeness of such minutes within thirty (30) calendar days of receipt.

4.1.4. Decision-Making and Dispute Resolution. The JDC will act by unanimous consent. The representatives of each Party will have collectively one vote on behalf of such Party; provided, however, that no such vote taken at a meeting will be valid unless at least one representative of each Party is present and participating in the vote. In the case of any matter which cannot be resolved unanimously by the JDC, at the written request of either Party, the dispute will be referred to senior management of the Parties in accordance with Section 13.1 (Escalation to Senior Management).

4.2. Joint Patent Committee.

4.2.1. Establishment of JPC. The Parties will establish a Joint Patent Committee (the “JPC”) to discuss the continued prosecution of the Licensed Patents and Product-Specific Patents, (including Joint Patents). The JPC will be comprised of at least one (1) senior patent attorney from each Party. Each Party will be free to change its members at its sole discretion. The JPC will exist for so long as the JDC exists. Thereafter, the Parties will meet from time to time as necessary, or as may

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

be mutually agreed by the Parties, to discuss patent related issues.

4.2.2. Responsibilities of the JPC. At least once per Calendar Quarter, the JPC will meet (in person or by phone) to discuss prosecution strategy for the Licensed Patents and Product-Specific Patents (including Joint Patents) with the goal of maintaining the broadest coverage for the Product in accordance with Section 9.3 (Filing, Prosecution and Maintenance of Patents). Subject to Section 9.5 (Enforcement of Patents and Know-How) and Section 9.6 (Claimed Infringement by Third Parties), the JPC will also discuss any (a) potential Third Party infringement of the Licensed Patents and Product-Specific Patents (including Joint Patents) that might affect the Product and (b) Third Party intellectual property right that the Parties may want to license or challenge.

4.2.3. Decision-Making and Dispute Resolution. Subject to Section 9.3 (Filing, Prosecution and Maintenance of Patents), in the event a dispute relates to the prosecution or maintenance of a Patent, Genzyme will have the ultimate sole decision-making authority with respect to the Product-Specific Patents and Licensed Product Patents and Isis will have the ultimate sole decision-making authority with respect to the Isis Core Technology Patents and the Isis Manufacturing and Analytical Patents. Any other dispute at the JPC will be referred to the JDC for resolution.

4.3. Expenses. Each Party will be responsible for all of its own travel and related costs and expenses for its members (or designees) of the JDC and JPC and such expenses will not be treated as Program Costs.

Article 5.
DEVELOPMENT

5.1. Development Plan and Development Budget. The initial Development Plan and Development Budget through the end of 2009 that have been agreed to by the Parties as of the Execution Date are attached to this Agreement as Exhibit A and Exhibit B, respectively. The Parties acknowledge and agree that the Development Plan and Development Budget as of the Execution Date will need to be updated and augmented by the JDC on a quarterly basis and also from time to time in the discretion of the JDC. The purpose of the Development Plan is to (a) set forth a strategy and plan for development, manufacturing and Approval for the Product, (b) detail the responsibilities and activities of Isis and Genzyme with respect to the development of the Product and (c) specify the expected timing of such activities, including the estimated dates of the initiation and completion of such activities. The Development Budget contains the estimated costs associated with the tasks outlined in the Development Plan. The JDC (or directly by the written mutual agreement of the authorized representatives of the Parties) may amend the Development Plan and Development Budget at any time, but, in any event, the JDC will review and update the Development Plan and Development Budget by agreeing to a Development Budget for each calendar year during the Term not later than November 15^th of the prior calendar year and prior to the commencement of each successive

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

calendar quarter during such calendar year. Any update or amendment to the Development Plan or Development Budget must be in writing. After the JDC has disbanded, if requested by either Party, Genzyme and Isis will meet as necessary at least annually on a mutually agreed schedule to review and evaluate progress under the Development Plan and expenditures relative to the Development Budget and to develop updates or amendments to the Development Plan and Development Budget, with decisions made by the Parties consistent with the principles contemplated for JDC decision making in Section 4.1.4 (Decision Making and Dispute Resolution).

5.2. Roles and Responsibilities.

5.2.1. Clinical Trials. The Development Budget includes the preclinical work and clinical trials to be conducted in and initiated in calendar year 2008 and classifies each item of preclinical work and clinical trials as “Isis Funded” or “Non Isis Funded.” The JDC will assign specific responsibilities with respect to the conduct of such work and trials and will develop a written plan for transitioning responsibility between the Parties; provided, however, that such transition plan will not delegate the JDC’s decision making authority to a Party. Except as otherwise determined by the JDC, Genzyme will conduct all clinical trials and all preclinical work for Mipomersen initiated in calendar year 2009 and thereafter. If pursuant to Section 4.1.4 (Decision-Making and Dispute Resolution) the JDC amends the Development Plan so as to increase the size or scope of a clinical study designated as “Isis Funded” (such as by increasing the number of patients or increasing the dosing period of a clinical study) and as a result of such increase the actual expenses associated with such study exceed [**]% of the amount budgeted for such study in the Development Budget as of the Execution Date, then the incremental cost and expenses for such study in excess of [**]% of such Development Budget amount will be considered “Non Isis Funded” (i.e. not “Isis Funded”) for purposes of Section 8.3 (Financial Provisions Related to Development Activities).

5.2.2. Performance of the Development Program. Each Party will use Commercially Reasonable Efforts to conduct all activities and responsibilities assigned to it under the Development Plan and in accordance with the Development Budget and to cooperate with and provide reasonable support to the other Party in such other Party’s conduct of activities under the Development Plan. Each Party will undertake its respective development activities, including its obligation to conduct clinical trials, in accordance with all Applicable Laws.

5.2.3. Responsibility. Except for those certain clinical trial responsibilities allocated to Isis as set forth in the Development Plan or other written document approved by the JDC, Genzyme will be responsible for all other aspects of the development of the Product.

5.3. Clinical and Launch Supplies. Isis will be responsible for manufacturing and supplying API for the Phase II clinical trials, the Pivotal Trial(s) and the initial commercial launch

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

of the Product, pursuant to a Supply Agreement the form of which is set forth on Exhibit C and a Quality Agreement the form of which is set forth on Exhibit D. In accordance with Section 8(a) and (b) of the Supply Agreement, the transfer price for the Product under the Supply Agreement will be Isis’ Fully Absorbed Cost of Goods, and all amounts paid by Genzyme to Isis under the Supply Agreement will be Program Costs under this Agreement. The quantity of API that Isis will be required to supply for commercial launch will be mutually agreed by the Parties and set forth in the Supply Agreement. If Isis cannot manufacture as set forth above, upon written request by Genzyme, Isis will transfer to Genzyme all documentation and information, and permit Genzyme to reference and use any regulatory filings, and otherwise fully cooperate with Genzyme to enable Genzyme to make or have made the API for use by Genzyme in accordance with the Agreement. Genzyme will be responsible for all finished drug product and placebo needed for clinical trials of Product and finished drug product for commercial sale.

5.4. Know-How Transfer.

5.4.1. Transfer to Genzyme. During the existence of the JDC (or after the dissolution of the JDC at Genzyme’s request), Isis will transfer to Genzyme and its representatives all material Product Know-How and Isis Manufacturing and Analytical Know-How within the possession or Control of Isis or any of its Affiliates, including all Regulatory Materials related to the Product; provided, however, that Isis will be required to deliver Isis Manufacturing and Analytical Know-How only to Genzyme or a Third Party manufacturer approved by Isis in accordance with Section 6.3 (Commercial Manufacture). Without limiting the generality of the foregoing:

(a) Before or promptly following the Execution Date, Isis will transfer any preclinical pharmacology and safety data, clinical data that then exists and any other information related to the Product that Genzyme may reasonably request. Thereafter during the Term, Isis will provide copies of all data from Isis’ clinical or preclinical activities undertaken pursuant to the Development Plan.

(b) Isis will promptly disclose in reasonable detail and in a reasonable manner specified by Genzyme the Product Know-How and Isis Manufacturing and Analytical Know-How learned, discovered, developed, acquired or otherwise coming within the Control of Isis during the Term.

(c) At Genzyme’s request from time to time during the Term, Isis will deliver to Genzyme copies (for documents and information) and samples (for materials) of any documents, files, diagrams, plans, specifications, designs, recipes, schematics, reports, models, prototypes, chemical or biologic materials, assays, reagents, or other tangible documentation or material in Isis’ possession recording or embodying the Product Know-How and Isis Manufacturing and Analytical Know-How in Isis’ or its Affiliate’s possession.

(d) At Genzyme’s request from time to time during the Term, and on a commercially reasonable schedule and at a commercially reasonable venue to be agreed on by the Parties, technically qualified personnel from each Party (and, if applicable, any Third Party manufacturer approved by Isis in accordance with Section 6.3 (Commercial Manufacture)) will meet and/or participate in telephone conference calls as reasonably necessary to exchange knowledge necessary to fully transfer all such Know-How.

(e) Section 2.2 (Limited Right to Sublicensee) and Article 12 (Confidentiality and Public Disclosures) will apply to any transfer of such Know How by Genzyme to a Third Party.

5.4.2. Transfer from Genzyme to Isis. Upon Isis’ reasonable request, Genzyme will provide to Isis copies of any and all data from Genzyme’s clinical or preclinical studies with the Product.

5.5. Subcontracting. Each Party may contract with one or more Third Party contractors to perform any or all of its obligations under the Development Plan; provided, however, that (a) except as otherwise agreed to by the JDC, each Third Party contractor will be approved by the JDC for the proposed work, such approval not to be unreasonably withheld, delayed or conditioned; and (b) the contracting Party provides the other Party with a true and accurate copy of each agreement pursuant to which such Third Party contractor is engaged promptly after execution thereof.

Article 6.
COMMERCIALIZATION AND REGULATORY MATTERS

6.1. Commercialization Responsibilities. Genzyme will have the exclusive right to commercialize any Product itself or through one or more Affiliates or Third Parties selected by Genzyme in the Territory and will have sole discretion, authority and responsibility in all matters relating to the commercialization of any Product in the Territory; provided, however, that Genzyme must use Commercially Reasonable Efforts to commercialize at least one Product in each of the Major Market Countries upon obtaining Approval in such country.

6.2. Regulatory Matters and Filings.

6.2.1. Regulatory Responsibility. Genzyme will be responsible for all regulatory matters relating to the Product in the Territory. Isis will transfer to Genzyme (or to a Genzyme Affiliate designated by Genzyme) the IND(s), orphan drug designation(s) and other existing Regulatory Materials for Mipomersen within thirty (30) days of the Execution Date. Between the Execution Date and the transfer to Genzyme of the IND related to the Product, Isis will not file or send any Regulatory Material related to the Product with or to any Regulatory Authority without Genzyme’s prior written consent, which consent will not unreasonably withheld or delayed. Genzyme will prepare and file, in its own name, all NDAs, MAAs and other Regulatory Materials for the Product in the

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

6.2.2. Third Party Services Agreements.

(a) Isis will exercise its rights under any agreement with a Third Party now existing or entered into during the Term pursuant to which Isis obtains services applicable to the pre-clinical or clinical development of a Product, including without limitation any agreement with a contract research organization (each a “Third Party Services Agreement”) in a manner that is as consistent as possible with the terms of this Agreement and in consultation with and as reasonably requested by Genzyme. Isis covenants that it will not, without Genzyme’s prior written consent, (i) agree, consent or acquiesce to any amendment, supplement or other modification to any Third Party Services Agreement or (ii) take any action under any Third Party Services Agreement, in each case that may adversely affect Genzyme as the holder of the Regulatory Materials related to the Product. Isis will take all reasonable actions necessary, or permit Genzyme to take such actions, to maintain and enforce its rights under the Third Party Services Agreements in a manner that is consistent with the terms of this Agreement.

(b) In connection with the transfer of the Regulatory Materials for Mipomerson and Genzyme’s assumption of responsibility for regulatory matters related to the Product, at Genzyme’s written request Isis will use commercially reasonable efforts to promptly assign and transfer to Genzyme any Third Party Services Agreements solely related to the pre-clinical or clinical development of the Products. If the terms of any Third Party Services Agreement requires the consent of the other party thereto to effect such assignment, then upon Genzyme’s request for an assignment, Isis will use commercially reasonable efforts to obtain such consent. In the event of any assignment to Genzyme under this Section 6.2.2, Genzyme will assume full responsibility for satisfying all obligations of Isis under any assigned agreement to the extent arising after such assignment and assumption, and Isis will remain responsible for satisfying all obligations under any assigned agreement to the extent arising prior to such assignment and assumption. If a Third Party Services Agreement relates both to the pre-clinical or clinical development of the Product and to the development of some other Isis product not licensed to Genzyme under this Agreement, then at Genzyme’s request, the Parties will use commercially reasonable efforts to enter into such amendment(s) or new agreement(s) with the Third Party service provider to effect the transfer to Genzyme of all rights and obligations related to the Product under such Third Party Services Agreement.

6.2.3. Regulatory Audit. If a Regulatory Authority desires to conduct an inspection or audit of a Party’s facility, or a facility under contract with a Party, with regard to a Product, then such Party will promptly notify the other Party and permit and cooperate with such inspection or audit, and will cause the contract facility to permit and cooperate with such Regulatory Authority and such other Party during such inspection or audit. Genzyme will have the right to have a representative observe such inspection or audit of a facility operated by Isis or under contract with Isis. Following receipt of the inspection or audit observations of such Regulatory Authority (a copy of which the audited Party will immediately provide to the other Party), the audited Party will prepare the response to any such

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

observations, and will provide a copy of such response to the other Party.

6.2.4. Class Generic Label Claims. Notwithstanding the foregoing, to the extent Genzyme intends to make any claims in a Product label that are of general applicability to antisense oligonucleotides, Genzyme will provide such claims to Isis in advance and will consider any proposals and comments made by Isis.

6.3. Commercial Manufacture.

6.3.1. Manufacture. Subject to Isis’ obligation to manufacture and supply API for the commercial launch of the Product pursuant to Section 5.3 (Clinical and Launch Supplies) and the Supply Agreement, Genzyme will be responsible for securing commercial quantities of API and finished drug product for the Product. If Genzyme chooses not to manufacture the API for Product itself, then prior to using any Third Party manufacturer to supply commercial quantities of the API for Product, Genzyme must obtain Isis’ prior written consent to the identity of the Third Party manufacturer and the material terms and conditions on which such Third Party manufacturer will supply commercial quantities of the API for Product, which consent will not be unreasonably withheld, conditioned or delayed; provided, however, that Isis will not withhold its consent to a Third Party manufacturer if its basis for doing so is an objection to the country in which such manufacturing will take place and the country in question is a member country of the European Union or Switzerland. In any event, Isis will cooperate with and provide commercially reasonable assistance to Genzyme and any approved Third Party manufacturer, including by transferring relevant Know-How in accordance with Section 5.4 (Know-How Transfer).

6.3.2. Assignment of Agreements With Third Parties. At Genzyme’s written request in connection with the transfer of responsibility for manufacture, Isis will use commercially reasonable efforts to promptly assign and transfer to Genzyme any existing supply or other agreements solely related to the manufacture of the Products. Concurrent with the Execution of this Agreement, Isis will assign and transfer to Genzyme its agreement with [**] related to the preparation and packaging of drug product. If the terms of any of the agreements referred to in the previous two sentences require the consent of the other party thereto to effect such assignment, then upon Genzyme’s request for an assignment, until Isis is able to obtain such consent and effect such assignment, Isis will exercise its rights under such agreements for the benefit of Genzyme and as reasonably requested by Genzyme. In the event of any assignment to Genzyme under this Section 6.3.2, Genzyme will assume full responsibility for satisfying all obligations of Isis under any assigned agreement to the extent arising after such assignment and assumption, and Isis will remain responsible for satisfying all obligations under any assigned agreement to the extent arising prior to such assignment and assumption.

6.4. Isis Safety Database. Isis maintains a 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 Database”). In an effort to maximize understanding of the safety profile and pharmacokinetics of Isis’ drug compounds, Genzyme will reasonably cooperate in providing information to Isis to populate the Isis Database by providing Isis with copies of toxicology, pharmacokinetic and serious adverse event final reports related to the Product, as well as any supporting data reasonably requested by Isis. Genzyme’s obligation under this Section 6.4 will be subject to Applicable Law, any necessary informed consents and obligations to Third Parties.

6.5. Safety Reporting. Each Party will designate a primary contact person for the receipt of all reports called for in this Section 6.5 (the “Primary Safety Contact Person”) and promptly notify the other Party of such designation or any change thereto. Each Party will notify the other Party’s Primary Safety Contact Person of (a) all available information concerning any serious adverse event (SAE) occurring in patients treated with the Product, for any indication, (b) any information, regardless of source, which is relevant to known or potential human safety risks associated with the Product, (c) signals of human risk including information from in vitro or animal studies which may suggest a significant hazard to humans, including any findings from tests in laboratory animals that suggest a significant risk to human beings, including reports of mutagenicity, teratogenicity or carcinogenicity, and (d) information related to other products that are chemically similar to the Product or that have a pharmacologically similar mechanism of action (e.g., antisense oligonucleotides) that suggests a significant hazard for humans related to the Product. For purposes of this Section 6.5, a “serious adverse event (SAE)” is one which has an outcome which (i) is fatal or life threatening, (ii) requires or prolongs in-patient hospitalization, (iii) is a persistent or significant disability/incapacity, (iv) is a congenital anomaly/birth defect, or (v) is an important medical event, e.g., required medical or surgical intervention to prevent one of the other serious outcomes listed above. Each Party will promptly (but no later than twenty-four (24) hours after it becomes aware of the serious adverse event (SAE) or such other information and as necessary for compliance with regulatory requirements) provide the other Party with all such safety information through the receiving Party’s Primary Safety Contact Person. Isis will conduct all safety reporting for the Product in accordance with Genzyme standard operating procedures communicated to Isis in writing. Upon transfer of the IND(s) to Genzyme and assumption by Genzyme of regulatory responsibilities under the IND(s), Genzyme will assume responsibility for the global safety database related to the Product. Genzyme 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 the Product and will furnish copies of such reports to Isis.

6.6. Commercial Forecasts & Plans.

6.6.1. In addition to the reports required under Section 8.6 (Periodic Reporting and Reconciliation), beginning on the last year in which the JDC is in place and each calendar year thereafter (1) not later than October 1st of the applicable year, Isis

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

will provide Genzyme with a non-binding, good-faith forecast of Isis’ aggregate Program Costs for the following calendar year if any; and (2) not later than November 15th of the applicable year (i) Genzyme will provide Isis with a non-binding, good-faith forecast of Genzyme’s aggregate Program Costs for the following calendar year, (ii) Isis will provide Genzyme with an updated non-binding, good-faith forecast of Isis’ aggregate Program Costs for the following calendar year, if any, and (iii) based upon the Parties’ non-binding forecasts of aggregate Program Costs, Genzyme will provide Isis with a non-binding, good-faith forecast of the Net Sales, Net Revenue and Net Profit for such year. Each Party’s forecasts will include sufficient supporting detail to allow the other Party an opportunity to review and understand the forecasts.

6.6.2. Prior to the initial commercial launch of the Product and on an annual basis thereafter, Genzyme will provide Isis with a reasonably detailed written summary of its marketing plan and budget and will consider in good faith all comments and suggestions provided by Isis on such plans and budgets.

Article 7.
RESEARCH RELATED TO THE PRODUCT

7.1. Research Programs. The Parties will agree to conduct research programs related to the Product that may include, but are not limited to, the following research topics: (a) [**], (b) [**], (c) [**] and (d) [**] (collectively, the “Research Programs”). The nature and scope of the Research Programs will be determined within sixty (60) days of the Execution Date by a subcommittee to be appointed the JDC.

7.2. Research Funding. Isis will fund all external research expenses incurred in calendar years [**] in connection with the Research Programs. Genzyme will fund all external research expenses incurred in connection with the Research Programs in calendar year [**]. Thereafter, the Parties will agree upon allocation of any external research expenses incurred in connection with the Research Programs. Each Party will be responsible for their own internal research expenses incurred in connection with the Research Programs, and, unless otherwise agreed in writing by the Parties, internal and external research expenses incurred in connection with the Research Program will not be included as Program Costs. For the purposes of this Section 7.2, “internal research expenses” means costs and expenses incurred in connection with the Research Programs attributable to the internal costs of base salary plus a factor for reasonable and customary employee benefits and payroll taxes for those employees directly responsible for performing the research activity plus G&A Costs and other overhead expenses reasonably required to support the activities of the Parties under the Research Programs as allocated consistent with the methodologies agreed to under Section 8.7.2.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

MAA Approval for the use of Mipomersen to treat patients who have polygenic hypercholesterolemia or any patient population of a size comparable to the patient population deemed to be at “high risk” as determined in accordance with the National Cholesterol Education Program’s clinical practice guidelines on cholesterol management with LDL-C greater than or equal to [**] mg/dL		$[**]
Approval of a Japanese New Drug Application for the use of Mipomersen to treat patients who have polygenic hypercholesterolemia or any patient population of a size comparable to the patient population deemed to be at “high risk” as determined in accordance with the National Cholesterol Education Program’s clinical practice guidelines on cholesterol management with LDL-C greater than or equal to [**] mg/dL		$[**]

The Parties acknowledge that the current Development Plan contemplates [one or more] Pivotal Trials, that, if successful, are currently intended to achieve the milestones set forth in Section 8.2.1(b). To minimize the likelihood of any disagreement between the Parties around whether an Approval based upon a successful Pivotal Trial is sufficient to satisfy any of the milestones set forth in Section 8.2.1(b), the Parties agree to adopt the following process:

(1) Prior to final approval of any Pivotal Trial protocol or any material change to the protocol of an ongoing Pivotal Trial by the JDC, Genzyme will notify the JDC in writing if Genzyme believes, were a Regulatory Authority to grant an Approval for the treatment of a patient population that is co-extensive with the patient population(s) included for enrollment in such Pivotal Trial, that such approval will not qualify to meet the milestones set forth in Section 8.2.1(b).

(2) If Genzyme fails to provide the JDC with the notice contemplated by subsection (1) above, an Approval in the relevant jurisdiction for the treatment of a patient population that is co-extensive with the patient population(s) included for enrollment in the Pivotal Trial will be deemed to satisfy the applicable milestone in Section 8.2.1(b).

(3) In addition, in the event a Regulatory Authority proposes a limitation that would, in Genzyme’s view, preclude the achievement of one of the milestones in Section 8.2.1(b), Genzyme will notify the JDC and in good faith attempt to avoid such restriction, to the extent practical under the circumstances. In such event, Genzyme will also reasonably consult with Isis regarding the best strategy to attempt to avoid such restrictions.

(c) Follow-On Compound. Within thirty (30) days after the achievement of the following indicated events by Genzyme, its Affiliate or its Sublicensee, Genzyme will pay Isis the following development milestone payments:

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

Milestone Event		Milestone Payment
NDA Approval for the Follow-On Compound		$[**]
MAA Approval for the Follow-On Compound		$[**]
Approval of a Japanese New Drug Application for the Follow-On Compound		$[**]

8.2.2. Commercial Milestones. Within thirty (30) days after the achievement of the following indicated events by Genzyme, its Affiliate or its Sublicensee, Genzyme will pay Isis the following commercial milestone payments:

Milestone Event	Milestone Payment
Annual Net Revenues for all Products equals or exceeds three billion dollars ($3,000,000,000) in each of any two consecutive calendar years	$	250,000,000
Annual Net Revenues for all Products equals or exceeds four billion dollars ($4,000,000,000) in each of any two consecutive calendar years	$	250,000,000
Annual Net Revenues for all Products equals or exceeds five billion dollars ($5,000,000,000) in each of any two consecutive calendar years	$	250,000,000

In the event that more than one of the above commercial milestones is achieved simultaneously, Genzyme will make only one milestone payment, which will be for the milestone requiring the highest Annual Net Revenues. The Annual Net Revenues in any calendar year may be counted toward only one consecutive two calendar year period, except that if Annual Net Revenues for all Products equals or exceeds five billion dollars ($5,000,000,000) in any calendar year, that year may be counted as both the last year of one two consecutive year period and the first year of a second two consecutive year period. For the purpose of illustration, it will require at least five (5) years before Genzyme has been required to pay Isis the total of the seven hundred and fifty million dollars ($750,000,000) in milestone payments pursuant to this Section 8.2.2 (Commercial Milestone) unless Annual Net Revenue exceeds five billion dollars ($5,000,000,000) for three (3) or more consecutive years, in which case it would require four (4) years (assuming there was at least three billion dollars ($3,000,000,000) in sales in the first or fourth year during the four year period).

8.2.3. Hybrid Milestones. Within thirty (30) days after the achievement of the following indicated events by Genzyme, its Affiliate or its Sublicensee, Genzyme will pay Isis the following milestone payments:

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

The earlier to occur of (A) NDA Approval for the use of Mipomersen to treat patients who have heterozygous FH or an otherwise comparably sized eligible patient population; or (B) annual Net Revenues for all Products equals or exceeds two hundred and fifty million dollars ($250,000,000) in any calendar year		$[**]
The earlier to occur of (A) NDA Approval for the use of Mipomersen to treat patients who have heterozygous FH or an otherwise comparably sized eligible patient population; or (B) annual Net Revenues for all Products equals or exceeds five hundred million dollars ($500,000,000) in any calendar year		$[**]

* For purposes of clarification, if the first hybrid milestone above had not already been payable, and annual Net Revenues for all Products equals or exceeds five hundred million dollars ($500,000,000) in a calendar year, then both hybrid milestones would be triggered.

8.2.4. Milestones Payable Only Once. Once Genzyme has made any particular milestone payment under this Section 8.2, Genzyme will not be obligated to make any payment under this Section 8.2 with respect to the re-occurrence of same milestone, whether or not such re-occurrence is with respect to a different or the same Product or indication.

8.2.5. Indications of Mipomersen Approval. If Mipomersen receives an Approval for a label indication that is sufficiently broad to include the entire patient population contemplated by one or more development milestone(s) set forth in Sections 8.2.1(a) (Mipomersen in FH) or 8.2.1(b) (Mipomersen in Other Indications) or 8.2.3 (Hybrid Milestones), then Genzyme will pay Isis the milestone payment(s) for such development milestone(s), even though the indication for which Mipomersen is approved is not identical to the indication(s) of such development milestone(s).

8.3. Financial Provisions Relating to Development Activities.

8.3.1. Isis Funding of External Development Expenses.

(a) Subject to Section 5.2.1 (Clinical Trials), Isis will fund the clinical studies described as “Isis Funded” in the Development Budget.

(b) In addition to its funding obligations under Section 8.3.1(a) above, Isis will fund the first one hundred and twenty-five million dollars ($125,000,000) of the External Development Expenses for the Product that will be incurred by the Parties in accordance with the Development Plan starting as of January 1, 2008, including expenses for (a) the clinical studies described as “Non Isis Funded” in the Development Budget, (b) future clinical studies undertaken in accordance with the Development Plan, (c) toxicology studies undertaken in accordance with the Development Plan (except for those described as “Isis Funded” in the Development Budget), (d) pharmacokinetic studies undertaken in accordance with

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

the Development Plan, (e) the manufacturing of API, as well as the packaging and distribution of the final Product and (f) the scientific advisory board and drug safety monitoring board. Any External Development Expenses that are recouped by Isis pursuant to Section 8.4 (Sharing of Net Revenue) will not be counted toward the fulfillment of this $125 million funding commitment. For purposes of clarity, in the event that Net Profit is achieved prior to the exhaustion of the Isis $125 million funding commitment set forth in this section 8.3.1, then for so long as Net Profit is maintained, Isis will not be obligated to fund External Development Expenses and the provisions of Section 8.5 (Sharing of Net Profits) will apply.

8.3.2. Shared Funding of External Development Expenses. After one hundred and twenty-five million dollars ($125,000,000) of External Development Expenses for the Product have been funded as described in Section 8.3.1(b) above, and after the sharing of Net Revenue in accordance with Section 8.4 (Sharing of Net Revenue), the Parties will share equally (on a 50/50 basis) all remaining External Development Expenses in any calendar year in which Net Profit is not achieved. In any calendar year in which Net Profit is achieved, the External Development Expenses will be included as Program Costs.

8.3.3. Internal Development Expenses. Each Party will be responsible for their own Internal Development Expenses with respect to development of the Product in any calendar year in which Net Profit is not achieved. In any calendar year in which Net Profit is achieved, the Parties’ Internal Development Expenses will be included as Program Costs.

8.4. Sharing of Net Revenue. In any calendar year in which there is not a Net Profit, the Parties will share Net Revenue as follows:

8.4.1. Costs of Goods. Net Revenue first will be allocated between the Parties to reimburse them for the Fully Absorbed Cost of Goods incurred by the Parties in such calendar year.

8.4.2. External Sales & Marketing Expenses. Once the Parties have each been fully reimbursed for the Fully Absorbed Cost of Goods, Net Revenue next will be allocated between the Parties to reimburse them for External Sales & Marketing Expenses incurred by the Parties in such calendar year.

8.4.3. Internal Sales & Marketing Expenses. Once the Parties have each been fully reimbursed for the Fully Absorbed Cost of Goods and External Sales & Marketing Expenses, Net Revenue next will be allocated between the Parties to compensate them for Internal Sales & Marketing Expenses incurred by the Parties in such calendar year.

8.4.4. External Development Expenses. Once the Parties have each been fully reimbursed for the Fully Absorbed Cost of Goods, External Sales & Marketing Expenses and Internal Sales & Marketing Expenses, Net Revenue next will be

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

allocated between the Parties to compensate them for External Development Expenses incurred by the Parties in such calendar year (other than Fully Absorbed Cost of Goods already reimbursed under Section 8.4.1 above).

8.4.5. Internal Development Expenses. Once the Parties have each been fully reimbursed for the Fully Absorbed Cost of Goods, External Sales & Marketing Expenses, Internal Sales & Marketing Expenses and External Development Expenses, Net Revenue next will be allocated between the parties to compensate them for Internal Development Expenses incurred by the Parties in such calendar year.

8.4.6. Revenue Sharing Proportional to Expenses. For each category of cost or expense set forth in this Section 8.3, if Net Revenue is sufficient to only partially compensate the Parties for particular category of cost or expense, then the Parties will allocate the Net Revenue that may be allocated for such category between the Parties on a pro rata basis in proportion to the relative amounts of such category of cost or expense incurred by each Party.

8.5. Sharing of Net Profits.

8.5.1. Responsibility for Net Loss. Except as set forth in Section 8.4 (Sharing of Net Revenue), in any calendar year in which there is a Net Loss, Genzyme’s share of Net Revenue will be one hundred percent (100%) and, subject to Section 8.3 (Financial Provisions Related to Development Activities), Genzyme will be solely responsible for all Program Costs. Isis will not be required to compensate Genzyme for any Net Loss.

8.5.2. Sharing of Net Profits. In any calendar year in which there is a Net Profit, the Parties will share such Net Profit in accordance with the following allocation based on Net Revenue for such calendar year:

Annual Net Revenue	Genzyme Percentage	Isis Percentage
$1 to < $200 M	70%	30%
[**]	[**]	[**]
[**]	[**]	[**]
[**]	[**]	[**]
[**]	[**]	[**]
[**]	[**]	[**]
[**]	[**]	[**]
[**]	[**]	[**]
[**]	[**]	[**]
[**]	[**]	[**]
>$2 B	50%	50%

Notwithstanding the foregoing, in any calendar year in which Net Profits are generated in an amount greater than or equal to [**] of Net Revenue, Isis’ share of

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

Net Profits will not fall below an amount equal to [**] of Net Revenue.

8.6. Periodic Reporting and Reconciliation.

8.6.1. Reports. Within thirty (30) days after the end of each Calendar Quarter during the Term (a “Reporting Period”), each Party will submit a written report to the other Party setting forth in reasonable detail the following, as applicable: (a) External Development Expenses incurred by Isis in accordance with Section 8.3.1 (Isis Funding of External Development Expenses) for each month during such Reporting Period, if any; (b) Fully Absorbed Costs of Goods, External Sales & Marketing Expenses, Internal Sales & Marketing Expenses, External Development Expenses, and Internal Development Expenses incurred by each Party for each month during such Reporting Period (if any); (c) actual Net Revenues, Net Sales and Program Costs incurred by or on behalf of the reporting Party for each month during such Reporting Period, if any, and (d) forecasts for the next four (4) Reporting Periods of Program Costs attributable to such Party (including, for each Party, the Fully-Absorbed Cost of Goods, External Sales & Marketing Expenses, Internal Sales & Marketing Expenses, External Development Expenses, and Internal Development Expenses) and, for Genzyme, Genzyme’s estimate of Net Revenues. Such written reports will provide supporting detail for actual Net Revenues, Net Sales and Program Costs. The Parties recognize that the forecasts provided pursuant to subsection (d) are estimates only, and the Party providing such forecasts for the next Reporting Period will have no liability to the other Party based thereon. The Parties agree to consider in good faith the utilization of more rapid and detailed reporting mechanisms in order to meet the reporting requirements of the Parties. Development Expenses reported pursuant to this Section 8.5.1 will be included in Program Costs for determining Net Profits or Net Losses (and any revenue sharing or resulting funding obligations under Sections 8.3 and 8.4), as applicable, only to the extent made or incurred in accordance with the Development Plan and to the extent that they do not exceed the amount budgeted for such expense in the then-current Development Budget (if any) by more than [**] for a calendar year or as otherwise approved by the JDC. Costs and expenses included in Program Costs, as well as the deductions taken from Net Sales, will not be double counted (i.e., any item of expense included in any expense category will not also be included in any other expense category).

8.6.2. Reconciliation.

(a) Within forty-five (45) days following the exchange of the reports under Section 8.6.1 (Reports), Genzyme will send to Isis a written report setting forth the calculation of any net amount owed by Genzyme to Isis (or by Isis to Genzyme), in order to ensure that (i) Isis fulfills its funding obligations under Section 8.3 (Financial Provisions Relating to Development Activities) and (ii) the Parties share Net Revenue as specified in Section 8.4 (Sharing of Net Revenue) or Net Profits as specified in Section 8.5.2 (Sharing of Net Profits). The Parties will

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

use the most recent forecasts for Annual Net Revenue and Net Profit provided pursuant to Section 8.6.1 (Reports) to determine the applicable Net Profit share in any given Calendar Quarter (other than in the final Calendar Quarter of any calendar year). The Parties will use the actual Annual Net Revenue and Net Profit for the calendar year to determine the applicable Profit Share percentage for the last Calendar Quarter in any calendar year.

(b) This reconciliation report will, among other things, contain (i) a tally of Isis’ fulfillment of its funding obligations under Section 8.3 (Financial Provisions Relating to Development Activities), which tally will include any necessary adjustments, (ii) appropriate retroactive adjustments for prior Calendar Quarters in the same calendar year to take into account increases (or decreases) in Isis’ share of Net Profits or Isis’ fulfillment of its funding obligations under Section 8.3 (Financial Provisions Relating to Development Activities) and (iii) appropriate credit for Program Costs directly incurred by Isis.

8.6.3. Payments. If the reconciliation conducted under Section 8.6.2 (Reconciliation) results in a payment being owed by Genzyme to Isis, then the net amounts payable will be paid by Genzyme to Isis within forty-five (45) days of Genzyme receiving confirmation from Isis that Genzyme’s report required by Section 8.6.2 (Reconciliation) is accurate. If the reconciliation conducted under Section 8.6.2 (Reconciliation) results in a payment being owed by Isis to Genzyme, then the net amounts payable will be paid by Isis within forty-five (45) days of its receipt of the reconciliation report.

8.6.4. Disputes. In the event of a dispute regarding any amount reported by a Party pursuant to Section 8.6.1 (Reports) or the amount owed under Section 8.6.2 (Reconciliation), the Parties will promptly meet and negotiate in good faith a resolution to such dispute. In the event that the Parties are unable to resolve such dispute within sixty (60) days after notice by the disputing Party, the Parties will (a) use commercially reasonable efforts to reach agreement on the appointment of one internationally-recognized independent accounting firm to determine the matter or (b) if the Parties cannot reach agreement on such accounting firm, then each Party will appoint one internationally-recognized accounting firm and such firms will choose a third internationally-recognized independent accounting firm to make the final determination. Interest will be payable on any disputed amounts determined to be due in the same manner as provided for in Section 8.10 (Interest on Late Payments), with interest accruing from the end of the thirty (30) day period during which such payment should have been made.

8.7. Accounting and Allocation Methods.

8.7.1. Accounting. To the extent possible in accordance with the terms and conditions of this Agreement, the Parties will account for all amounts required to be determined under this Agreement (including Net Profits, Net Revenues, Program Costs, and all elements of any of the foregoing) in accordance with GAAP,

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

consistently applied. Where more than one accounting treatment is possible consistent with the terms and conditions of this Agreement and GAAP, each Party will account for amounts in a manner that is consistent with the manner in which such Party accounts for similar amounts for the purposes of its publicly reported financial statements.

8.7.2. Allocation Methods. Promptly upon the execution of this Agreement and before the start of each successive fiscal year of the Term, the Parties will agree upon a consistently applied methodology for determining and allocating to Program Costs (including Development Expenses and Sales and Marketing Expenses) for such year an appropriate portion of each of their respective (i) costs and expenses that relate both to the Product and any of the Parties’ other products or programs and (ii) G&A Costs and other overhead attributable to this Agreement.

8.8. Audits and Interim Reviews. Each Party will maintain accurate books and records regarding Program Costs, Fully-Absorbed Cost of Goods, External Sales & Marketing Expenses, Internal Sales & Marketing Expenses, External Development Expenses, and Internal Development Expenses, Net Revenues and Net Sales, as applicable, sufficient to enable the calculation of amounts payable hereunder to be verified, and will retain such books and records for each quarterly period for three (3) years after submission of the corresponding report pursuant to this Agreement. Either Party will have the right to request that an independent certified public accountant selected by it (but excluding its own accountant) and reasonably acceptable to the other Party perform an audit, not more than once in any four (4) consecutive Calendar Quarters during the Term, but including one post-termination audit and, if any such audit results in a material restatement of records (i.e., a discrepancy of 5% or more for any calendar year), such Party will be permitted an additional examination within such four (4) quarter period, of the other Party’s books of accounts covering the preceding three (3) year period for the sole purpose of verifying compliance with the payment provisions of this Agreement. Such audits will be conducted at the expense of the requesting Party at reasonable times during regular business hours and upon at least twenty (20) business days’ prior notice. Audit results will be shared with both Parties, subject to Article 12 (Confidentiality); provided, however, that the accounting firm may not disclose copies of the audited Party’s books of accounts (or excerpts thereof) to the other Party. Any accounting firm conducting such an audit will enter into a confidentiality agreement with both Parties containing restrictions substantially similar to the confidentiality provisions of Article 12 (Confidentiality) limiting the disclosure and use of information contained in such books and records for the purposes expressly permitted by this Section 8.8. Any inspection or audit pursuant to this Section 8.8 will be at the expense of the Party initiating the audit; provided, however, that if the Party’s accountants reasonably determine that Net Profits or Net Revenues have been understated or Program Costs (including associated labor costs, reimbursable costs and expenses) or Fully-Absorbed Cost of Goods, External Sales & Marketing Expenses, Internal Sales & Marketing Expenses, External Development Expenses, and Internal Development Expenses have been overstated by an amount equal to or greater than five percent (5%), for any calendar year, the audited Party will pay the reasonable fees of such accountants for such audit, in addition to remitting the Net Profits

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

or refund of Net Losses, Program Costs, Fully-Absorbed Cost of Goods, External Sales & Marketing Expenses, Internal Sales & Marketing Expenses, External Development Expenses, or Internal Development Expenses with interest thereon computed in accordance with Section 8.10 (Interest on Late Payments).

8.9. Withholding Taxes. If Applicable Law requires that taxes be withheld from payments made hereunder, or from Net Revenue or Net Profits, the Party making such payments or otherwise responsible for such withholding (the “Withholding Party”) will (a) deduct such taxes from any payments to which they relate or in the case of taxes withheld from the other Party’s share of Net Revenues or Net Profits account for such taxes as amounts paid on behalf of the other Party, (b) timely pay such taxes to the proper authority and (c) send written evidence of payment to the Party with respect to which such taxes were withheld or paid within sixty (60) days after payment. Taxes withheld from payments made hereunder will be treated as amounts received by the Party with respect to which such taxes were withheld for all purposes under this Agreement. If the Withholding Party is required to withhold and pay over taxes on the other Party’s share of Net Revenues or Net Profits, the other Party will promptly reimburse or otherwise make whole the Withholding Party for any amounts so withheld upon receipt of written evidence of the payment of such taxes. Any taxes paid (excluding income taxes) by the Withholding Party on the other Party’s share of Net Revenues or Net Profits for which the Withholding Party has not been reimbursed or otherwise made whole within thirty (30) days after the end of each Reporting Period will be treated as an amount received by the other Party (and not by the Withholding Party) for purposes of determining amounts owed under Section 8.6.2 (Reconciliation). Each Party will assist the other Party or Parties in claiming tax refunds, deductions or credits at such other Party’s request and will cooperate to minimize any withholding tax as permitted by Applicable Law.

8.10. Interest on Late Payments. Any payments to be made hereunder that are not paid on or before the date such payments are due under this Agreement will bear interest at a rate per annum equal to the lesser of (x) 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 one percent (1%) or (y) the maximum rate permissible under applicable law.

8.11. Currency; Payment. All amounts payable under this Agreement will be paid in United States dollars in immediately available funds, and will be directly deposited to a bank account designated for this purpose from time to time by the Party to receive payment. Isis will provide the necessary bank account information to Genzyme no later than the Execution Date and may update such information from time to time by written notice. The Parties may vary the method of payment set forth herein at any time upon mutual agreement, consistent with Applicable Law. As applicable, Net Sales, Net Sales Adjustments, and other elements of Net Revenue and Program Costs will be translated into United States dollars at the exchange rate used by Genzyme for public financial accounting purposes in accordance with GAAP. If, due to restrictions or prohibitions imposed by national or international authority, payments cannot be made as provided in this Article 8 (Financial Provisions) with respect to sales occurring outside of the United States, the Parties will consult with a view to finding a prompt and acceptable solution,

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

and Genzyme will deal with such monies as Isis may lawfully direct.

8.12. Material Safety Warnings. Notwithstanding the financial provisions contained in this Article 8 (Financial Provisions), in the event that the approved label for the Product [**], which is not anticipated by the Parties as of the Effective Date, the Parties will discuss in good faith (without obligation) the extent to which such [**] change the [**] for the Product.

Article 9.
INTELLECTUAL PROPERTY MATTERS

9.1. Product-Specific Patents.

9.1.1. Assignment of Product-Specific Patents. Isis will assign and transfer, and hereby does assign and transfer, to Genzyme, all rights, title, and interests in and to the Product-Specific Patents and all claims and causes of action arising from or relating to the Product-Specific Patents, including all rights to recovery for damages from infringement arising prior to, on or after the Execution Date. Simultaneously with the execution of this Agreement, Isis will execute and deliver a confirmatory assignment relating to all Product-Specific Patents in existence on the Execution Date in the form attached to this Agreement as Exhibit E.

9.1.2. Disclosure of Future Product-Specific Patents. Upon becoming aware of any potentially patentable invention Controlled by Isis that would, if patented, be included within the definition of Product-Specific Patents or Licensed Patents, Isis will promptly disclose such invention to Genzyme in writing in reasonable detail.

9.1.3. Covenants in Support of Assignment. Isis will provide all further cooperation which Genzyme reasonably determines is necessary to accomplish the complete transfer of the Product-Specific Patents and all associated rights to Genzyme, and to ensure Genzyme the full and quiet enjoyment of the Product-Specific Patents including executing and delivering further assignments, consents, releases and other commercially reasonable documentation, and providing good faith testimony by affidavit, declaration, deposition, in-person or other proper means and otherwise assisting Genzyme in support of any effort by Genzyme to establish, perfect, defend or enforce its rights in the Product-Specific Patents through filing and prosecution of Product-Specific Patents, interferences, oppositions, other regulatory proceedings, litigation, or other means. Isis will obtain the cooperation of the individual inventors of any inventions disclosed in the Assigned Product Specific Patents, including (a) obtaining signatures of such inventors on any patent applications or other documentation reasonably necessary to obtain patent protection for such inventions and (b) procuring (at Genzyme’s expense) such inventors’ good faith testimony by affidavit, declaration, deposition in-person or other proper means in support of Genzyme’s efforts in establishing,

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

perfecting, defending or enforcing patent rights to such inventions. To the extent Isis cannot transfer and assign the Product-Specific Patents, or any portion thereof, as of the Execution Date, then Isis will transfer and assign such Product-Specific Patents to Genzyme at its first opportunity to do so and pending such transfer and assignment such Product-Specific Patents will be deemed to be Licensed Patents for the purposes of Section 2.1 (Product License). To the extent further transfer or assignment of the Product-Specific Patents is required or permitted and Isis has not executed and returned to Genzyme the form of assignment reasonably requested by Genzyme within ten (10) business days of the delivery of such assignment to Isis at the address for notices set forth in Section 14.5 (Notices), then Isis hereby irrevocably appoints Genzyme as its attorney-in-fact with the right, authority and ability to execute and enter into such assignment on behalf of Isis. Isis stipulates and agrees that such appointment is a right coupled with an interest and will survive the unavailability of Isis at any future time.

9.1.4. Grant-Back License. Subject to the terms and conditions of this Agreement, Genzyme hereby grants Isis a non-exclusive, non-transferable license (with no right to sublicense) under the Product-Specific Patents to the extent necessary to perform Isis’ obligations under this Agreement and the Supply Agreement.

9.2. Program IP.

9.2.1. Ownership. Unless prohibited by Applicable Law, inventorship and authorship will be determined in accordance with U.S. patent and copyright law. Genzyme will own all Genzyme Program IP . Subject to the terms and conditions of this Agreement including Section 2.1 (Product License) and Section 9.1 (Product-Specific Patents), Isis will own all Isis Program IP, and Isis and Genzyme will jointly own all Joint Program IP. Subject to the terms and conditions of this Agreement including Section 2.1 (Product License), Section 9.1 (Product-Specific Patents), 9.2.3 (No Encumbrances) and Article 3 (Exclusivity), each Party will have the right to practice and license the Joint Program IP without consent of the other Party (where consent is required by law, such consent is deemed hereby granted) and without a duty of accounting to the other Party; provided, however that Isis will not grant a license to a Third Party under Joint Program IP to develop or commercialize any nucleic acid molecule whose primary purpose at the time of the license or primary therapeutic benefit at the time of commercialization is to cause the [**], without Genzyme’s prior written consent. Notwithstanding the foregoing, Isis will not be in breach of the preceding sentence if, despite exercising commercially reasonable efforts, it inadvertently licenses Joint Know-How to such a Third Party without Genzyme’s prior written consent, unless, prior to Isis disclosing such Joint Know-How to such a Third Party licensee, Genzyme provides Isis with a written summary description of such Joint Know-How that clearly indicates it is Joint Know-How under this Agreement. Subject to the terms and conditions of this Agreement, each Party will cooperate with the other Party’s efforts to establish, perfect, defend and

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

enforce its rights in its Program IP in the Territory. This Section 9.2.1 will be subject to the terms and conditions of Section 9.3.2 (Terms of Sharing Arrangement).

9.2.2. Cooperation/Compensation of Employees. Each Party represents and agrees that (a) all of its employees and all of its Affiliates’ employees acting under its or its Affiliates’ authority in the performance of this Agreement or pursuant to the Product License will be obligated under a binding written agreement or established corporate policy to assign to such Party, or as such Party will direct, all Technology and Patents discovered, made, conceived by such employee as a result of such employee’s employment, and (b) both it and its Affiliates have taken all appropriate actions under the Applicable Law in the Territory to ensure proper compensation to any employee for the assignment of such Technology and Patents as contemplated hereunder. In the case of all others acting in the performance of the Development Program or Research Programs or pursuant to the Product License, such as consultants, subcontractors, licensees, sublicensees, outside contractors, clinical investigators, agents, or non-employees working for non-profit academic institutions, such others will also be obligated under an agreement that meets the criteria of the preceding sentences, unless otherwise approved by the Parties. The Parties agree reasonably to undertake to enforce the agreements referenced in this Section 9.2.2 (including, where appropriate, by legal action) considering, among other things, the commercial value of such Technology and Patents.

9.2.3. No Encumbrances. Except as expressly provided in this Agreement, neither Party will sell, transfer, assign, mortgage, pledge, lease, grant a security interest in (e.g., as collateral for a loan or other financing) or otherwise encumber in the Territory any Joint Program IP necessary or useful for the research, development, manufacture or commercialization of the Product in the Territory without the prior written consent of the other Party; provided, however, that nothing contained in this Section 9.2.3 will prohibit an assignment permitted by Section 14.7 (Binding Effect; Assignment) or a license permitted by Section 9.2.1 (Ownership).

9.3. Manufacturing Improvements.

9.3.1. Background. As part of its collaborations with other pharmaceutical partners, Isis has an arrangement where Isis can share manufacturing technology improvements made by such pharmaceutical partners with other third parties so long as such third parties similarly agree to share their manufacturing technology improvements. After reviewing the proposed terms of such arrangement, Genzyme is willing to participate in the arrangement only with the clarifications and under the terms set forth in this Section 9.3 (Manufacturing Improvements).

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

9.3.2. Terms of Sharing Arrangement.

(a) During the period beginning on the Effective Date and ending [**] (the “Sharing Period”), the Parties will meet at least annually to review Manufacturing Improvements developed by either of the Parties during the Sharing Period during and in connection with the conduct of the Development Program or the Research Programs or commercializing the Product and, in the case of Isis, any Manufacturing Improvements made by or on behalf of Isis or any Participating Isis Partners and disclosed to Isis pursuant to a Sharing Agreement. The Parties will disclose all Manufacturing Improvements Controlled by such Party (including, in the case of Isis, Manufacturing Improvements made by other Participating Isis Partners and disclosed to Isis pursuant to a Sharing Agreement) in reasonable detail as to enable the other Party to use such Manufacturing Improvements in the manufacture of ASO Products. All such disclosures will be subject to appropriate confidentiality obligations. Isis will have the right to disclose and sublicense any Manufacturing Improvements Controlled by Genzyme only to Third Parties that are licensees of Isis with respect to the commercialization of one or more ASO Products and are Participating Isis Partners and only in accordance with Section 9.3.2(b).

(b) Without limiting the generality of Section 9.2.1 (Ownership), all rights, title, and interests in and to all Manufacturing Improvements developed or invented during the Sharing Period during and in connection with the conduct of the Development Program or the Research Programs or commercializing the Product solely by Genzyme’s employees or Third Parties acting on Genzyme’s behalf (“Genzyme Manufacturing Improvements”) will be the sole and exclusive property of Genzyme. Genzyme hereby grants Isis a worldwide, royalty-free, perpetual, non-exclusive license to practice under Genzyme’s rights to any Know-How in or Patent Covering such Genzyme Manufacturing Improvements Controlled by Genzyme to make and have made ASO Products other than the Product. The license granted under this Section 9.3.2(b) is sublicensable by Isis to Participating Isis Partners solely in connection with a license to develop, make, use, import, offer for sale and sell an ASO Product developed or commercialized by a Participating Isis Partner. Such Participating Isis Partners may not further disclose or sublicense Genzyme Manufacturing Improvements except in connection with a sublicense of the ASO Product being developed or commercialized under license from Isis. The license granted under this Section 9.3.2(b) will survive the termination of this Agreement with respect to any Genzyme Manufacturing Improvements made prior to such termination.

(c) Without limiting the generality of Section 9.2.1 (Ownership), all rights, title, and interests in and to all Manufacturing Improvements developed or invented during the Sharing Period solely by Isis’s employees or Third Parties acting on Isis’ behalf (“Isis Manufacturing Improvements”) will be the sole and exclusive property of Isis. Without limiting the rights granted to Genzyme in Article 2, Isis hereby grants Genzyme a worldwide, royalty-free, perpetual, non-exclusive license to practice under Isis’ rights to any Know-How in or Patent Covering any Manufacturing Improvements Controlled by Isis (including any

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

Manufacturing Improvements made by or on behalf of any Participating Isis Partners) to make and have made the Product and other ASO Products developed or commercialized by Genzyme. The license granted under this Section 9.3.2(c) is sublicensable by Genzyme solely in connection with a license to develop, make, use, import, offer for sale and sell an ASO Product developed or commercialized by Genzyme under license from Isis (including the Product). The license granted under this Section 9.3.2(c) will survive the termination of this Agreement or any Sharing Agreement with respect to any Manufacturing Improvements (including any Manufacturing Improvements made by Participating Isis Partners) made prior to such termination.

(d) Notwithstanding Section 9.2.1 (Ownership) and subject to Section 9.1 (Product-Specific Patents), all rights, title, and interests in and to all Manufacturing Improvements developed or invented during the Sharing Period jointly by Isis’ and Genzyme’s employees or Third Parties acting on Isis’ and Genzyme’s behalf will be the joint property of Isis and Genzyme with each party having an undivided joint interest in such Manufacturing Improvements. Each Party may license its rights under such Manufacturing Improvements for its own account and without the consent of the other Party (where consent is required by law, such consent is deemed hereby granted) and without a duty of accounting to the other Party, subject in all cases to the licenses granted to Genzyme under Article 2 (Licenses).

9.3.3. [**].

9.3.4. [**] Manufacturing Improvements. If Isis does not [**] of the Execution Date, Isis will [**]. In such event, Isis will be solely responsible for all costs and expenses associated with such development effort and will reimburse Genzyme for any such costs and expenses incurred by Genzyme. Failure of Isis to reimburse Genzyme for such costs and expenses will be deemed to be a material breach of this Agreement entitling Genzyme to setoff such amounts pursuant to Section 11.4.2 (Genzyme’s Right of Setoff).

9.3.5. Representations Regarding [**]. Isis represents and warrants to Genzyme as follows:

(a) [**], Isis will Control all Know-How [**] that is [**] the manufacture, development or commercialization of Mipomersen, including the [**] Manufacturing Improvements and will have the sufficient legal and/or beneficial title and ownership or rights to grant the Product License to Genzyme under such Know-How and the grant of such license to Genzyme does not violate the terms of any Third Party Agreement or any other agreement Isis has with a Third Party [**].

(b) If [**], Isis will Control all Know-How [**] that is [**] the manufacture, development or commercialization of Mipomersen as of such date and will have

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

the sufficient legal and/or beneficial title and ownership or rights to grant the Product License to Genzyme under such Know-How and the grant of such license to Genzyme does not violate the terms of any Third Party Agreement or any other agreement Isis has with a Third [**].

9.3.6. [**] Sharing Agreement. Isis will use reasonable efforts to [**].

9.3.7. Cooperation. Genzyme will provide reasonable cooperation with Isis’ efforts to [**]. In no event, however, will Genzyme be required to enter into any agreement that (i) [**] in any way or (ii) imposes any material obligations, liabilities or constraints on Genzyme except those contemplated by this Agreement.

9.4. Filing, Prosecution and Maintenance of Patents.

9.4.1. Responsibility.

(a) Product-Specific Patents and Genzyme Program Patents. Genzyme, through counsel of its choosing and at its sole expense, will be responsible for and have control over obtaining, prosecuting (including any interferences, reissue proceedings, re-examinations and oppositions), and maintaining throughout the Territory the Product-Specific Patents and Genzyme Program Patents in Genzyme’s name and Isis will cooperate with Genzyme in regard thereto. Without limiting the generality of the foregoing, Genzyme may, in its sole discretion, elect not to pursue patent protection for any Product-Specific Patent(s) and Genzyme Program Patent(s) in one or more countries in the Territory. Genzyme will consider input from the JPC regarding prosecution strategy for the Product-Specific Patents and Genzyme Program Patents, but will make all decisions relating to the prosecution and maintenance of Product-Specific Patents and Genzyme Program Patents.

(b) Licensed Product Patents.

(i) Primary Responsibility. Subject to Section 9.4.2(a) (Election Not to Continue Prosecution; Abandonment) and this Section 9.4.1(b), Genzyme, through counsel of its choosing and at its sole expense, will have primary responsibility for and control over obtaining, prosecuting (including any interferences, reissue proceedings, re-examinations and oppositions), and maintaining throughout the Territory the Licensed Product Patents and Isis will cooperate with Genzyme in regard thereto; provided, however that Genzyme will prosecute such Licensed Product Patents such that they do not claim (x) [**] other than apoB, or (y) methods of using such nucleic acids as a therapeutic or [**] other than apoB. Genzyme will consider input from Isis regarding prosecution strategy for the Licensed Product Patents, but will make all decisions relating to the prosecution and maintenance of Licensed Product Patents.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

(ii) Prosecution Strategy. In prosecuting Licensed Product Patents, the Parties will avoid filing patent applications that both claim (a) [**] apoB, (b) the [**] of apoB, (c) the specific composition of matter of a Product, or (d) methods of using Product as a therapeutic, methods of using Product to modulate apoB, or methods of using the Product to inhibit expression of apoB, and also claim (x) [**] other than apoB, or (y) methods of using such nucleic acids as a therapeutic or [**] other than apoB.

(c) Isis Core Technology Patents and the Isis Manufacturing and Analytical Patents. Subject to Section 9.4.2(b) (Election Not to Continue Prosecution; Abandonment), Isis, through counsel of its choosing and at its sole expense, will have primary responsibility for and control over obtaining, prosecuting (including any interferences, reissue proceedings, re-examinations and oppositions), and maintaining throughout the Territory the Isis Core Technology Patents and the Isis Manufacturing and Analytical Patents (in each case, other than Joint Patents), and Genzyme will cooperate with Isis in regard thereto. Isis will consider input from the JPC regarding prosecution strategy for the Isis Core Technology Patents, Isis Manufacturing and Analytical Patents (in each case, other than Joint Patents) and will consult with Genzyme before taking any action that would have an adverse impact on the scope of claims within the Special Isis Core Technology Patents (other than Joint Patents). However, Isis will make all decisions relating to the prosecution and maintenance of the Isis Core Technology Patents and Isis Manufacturing and Analytical Patents (in each case, other than Joint Patents). For clarity, this Section 9.4.1(c) will not apply to Joint Patents that are Isis Core Technology Patents or Isis Manufacturing and Analytical Patents, which will be governed Section 9.4.1(d) below.

(d) Joint Patents. Subject to Section 9.4.1(a) (Product-Specific Patents and Genzyme Program Patents) and Section 9.4.1(b) (Licensed Product Patents), with respect to any Joint Patent (other than Product-Specific Patents and Licensed Product Patents), the JPC will designate one Party (the “Responsible Party”) who will have primary responsibility for the preparation, filing, prosecution and maintenance of any such Joint Patent in the Territory (in both Genzyme’s and Isis’ name), using patent counsel selected by the JPC or otherwise agreed by the Parties. If the JPC has disbanded, the Parties will mutually agree on a Responsible Party. Each Party will assist the Responsible Party in the preparation, filing, prosecution and maintenance of such Joint Patents. The Responsible Party will consult with and keep the other Party (through the JPC if possible) informed of important issues relating to the preparation, filing, prosecution and maintenance of the Joint Patents (other than Product-Specific Patents or Licensed Product Patents) and will furnish the other Party (through the JPC if possible) with copies of documents relevant to such preparation, filing, prosecution or maintenance in sufficient time prior to filing such document or making any payment due thereunder to allow for review and comment by the other Party and, to the extent possible in the reasonable exercise of its discretion,

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

the Responsible Party will incorporate all such comments. If the Responsible Party decides to discontinue the preparation, filing, prosecution or maintenance of a Joint Patent (other than a Product-Specific Patent or Licensed Product Patent), the Responsible Party will notify the other Party at least sixty (60) days prior to any deadline that, if missed, would materially prejudice the Joint Patent, and the other Party will have the right to prepare, file, prosecute and maintain such Patent. The Parties will share equally the reasonable costs and expenses of the preparation, filing, prosecution and maintenance of such Joint Patents (other than Product-Specific Patents and Licensed Product Patents), and such costs and expenses will be considered Program Costs. Neither Party will make any statements or omissions or take any other action during prosecution or enforcement of any Joint Patent (other than Product-Specific Patents and Licensed Product Patents) which admits or concedes that any of the Licensed Patents (or any Product-Specific Patent) is invalid or unenforceable, which adversely affects or limits the scope of any claims in any such Patent, or which adversely affects the other Party’s rights under this Agreement in any way, without the prior written consent of the other Party. For clarity, this Section 9.4.1(d) does not apply to Joint Patents that are Product-Specific Patents or Licensed Product Patents, which are governed by Section 9.1 (Product-Specific Patents) and Section 9.4.1(a) and Section 9.4.1(b) above, but does apply to Joint Patents that are Isis Core Technology Patents or Isis Manufacturing and Analytical Patents.

9.4.2. Election Not to Continue Prosecution; Abandonment.

(a) If Genzyme elects not to file for or continue the prosecution (including any interferences, oppositions, reissue proceedings and re-examinations) or maintenance of a Licensed Product Patent in a particular country in the Territory, then Genzyme will notify Isis promptly in writing of its intention in good time to enable Isis to meet any deadlines by which an action must be taken to establish or preserve any such rights in such Patent in such country and Isis will have the right, but not the obligation, to file for or continue the prosecution or maintenance of such Patent in such country, and Genzyme will cooperate with Isis in regard thereto. In such event, Isis’ expenses incurred in connection with the prosecution or maintenance of such Patent in such country will be Program Costs.

(b) If Isis elects not to file for or continue the prosecution (including any interferences, oppositions, reissue proceedings and re-examinations) or maintenance of a Special Isis Core Technology Patent (other than Joint Patents), then, Isis will notify Genzyme promptly in writing of its intention in good time to enable Genzyme to meet any deadlines by which an action must be taken to establish or preserve any such rights in such Patent in such country and Genzyme will have the right, but not the obligation, to file for or continue the prosecution or maintenance of such Patent in such country, and Isis will cooperate with Genzyme in regard thereto. In such event, Genzyme’s expenses incurred in connection with the prosecution or maintenance of such Patent in such country will be Program Costs. For clarity, this Section 9.4.2(b) will not apply to Joint

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

Patents that are Special Isis Core Technology Patents, which will be governed Section 9.4.1(d) (Joint Patents).

9.4.3. Cooperation. Each Party hereby agrees: (a) to make its employees, agents and consultants reasonably available to the other Party (or to the other Party’s authorized attorneys, agents or representatives), to the extent reasonably necessary to enable such Party to undertake patent prosecution as contemplated by this Agreement; (b) to cooperate, if necessary and appropriate, with the other Party in gaining patent term extensions wherever applicable to Patents that are subject to this Agreement; and (c) to endeavor in good faith to coordinate its efforts with the other Party to minimize or avoid interference with the prosecution and maintenance of the other Party’s patent applications that are subject to this Agreement.

9.5. Enforcement of Patents and Know-How.

9.5.1. Notification. Each Party will promptly report in writing to the other Party during the Term any (a) known or suspected Third Party infringement of any Product-Specific Patents, Licensed Product Patents, Special Isis Core Technology Patent, or (b) known or suspected Third Party infringement of any Isis Core Technology Patents or Isis Manufacturing and Analytical Patents to the extent the infringement relates to a product that contains a nucleic acid that hybridizes to a nucleic acid molecule encoding apoB, or (c) unauthorized use or misappropriation of any Product Know-How or other Confidential Information by a Third Party of which it becomes aware, and will provide the other Party with all available evidence supporting such infringement or unauthorized use or misappropriation.

9.5.2. Rights to Enforce.

(a) Genzyme First Right. Genzyme will have the first right, but not the obligation, to take any reasonable measures it deems appropriate to stop activities in the Territory infringing the Product-Specific Patents, Licensed Product Patents or the use without proper authorization of any Product Know-How or the infringement of any Isis Core Technology Patent by a Third Party product that contains a [**] encoding apoB, including (i) initiating or prosecuting an infringement or other appropriate suit or action against or (ii) granting adequate rights and licenses necessary for continuing such activities in the Territory to any Third Party who at any time has infringed, or is suspected of infringing, any Product-Specific Patents or Licensed Product Patents or has used or is suspected of using without proper authorization the Product Know-How. If Genzyme desires to assert an Isis Core Technology Patent pursuant to this Section 9.5.2(a) and the infringing product is also Covered by a Product-Specific Patent, then Genzyme will assert both the Product-Specific Patent and the Isis Core Technology Patent, unless it obtains Isis’ written consent to assert only the Isis Core Technology Patent. In such a case, at Genzyme’s request Isis’ representatives will meet with Genzyme’s representatives to discuss whether it

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

would be advisable to assert an Isis Core Technology Patent without also asserting a Product-Specific Patent.

(b) Isis First Right. Subject to Section 9.5.2(a) (Genzyme First Right to Enforce), Isis will have the first right, but not the obligation, to take any reasonable measures it deems appropriate to stop activities in the Territory infringing the Isis Core Technology Patents or Isis Manufacturing and Analytical Patents (in each case, other than Joint Patents) or the use without proper authorization of any Isis Manufacturing and Analytical Know-How (other than Joint Know-How), including (i) initiating or prosecuting an infringement or other appropriate suit or action against or (ii) granting a Permitted License to any Third Party who at any time has infringed, or is suspected of infringing, any Isis Core Technology Patents or Isis Manufacturing and Analytical Patents (other than Joint Patents) or has used or is suspected of using without proper authorization the Isis Manufacturing and Analytical Know-How (other than Joint Know-How). For clarity, this Section 9.5.2(b) will not apply to Joint Patents that are Isis Core Technology Patents or Isis Manufacturing and Analytical Patents, which will be governed Section 9.5.2(c) (Joint Patents and Know-How).

(c) Joint Patents and Know-How. Subject to Section 9.5.2(a) (Genzyme First Right to Enforce), Isis and Genzyme will confer and may agree jointly to take any reasonable measures they deem appropriate to stop activities in the Territory infringing the Joint Patents (other than Product-Specific Patents and Licensed Product Patents) or the use without proper authorization of any Joint Know-How and any expenses of taking such measures will be included as Program Costs. If the Parties do not agree on whether or how to proceed with enforcement activity within either (i) sixty (60) days following the notice of alleged infringement or (ii) ten (10) days before the time limit to respond, if any, set forth in the Applicable Law for the filing of such actions, whichever comes first, then either Party may commence litigation with respect to the alleged or threatened infringement at its own expense. In the event a Party brings an infringement action, the other Party will cooperate reasonably at the litigating Party’s expense, including being joined as a party-plaintiff and providing good faith testimony. The other Party will have the right, at its expense, to retain its own counsel to monitor such litigation, and the costs associated with such monitoring will not be Program Costs. Neither Party will have the right to settle any patent infringement or Know-How misappropriation litigation under this Section in a manner that diminishes the rights or interests of the other Party without the express written consent of such other Party. For purposes of clarification, the grant of a license under a Joint Patent to a Third Party that would not otherwise result in a breach under this Agreement will not be considered to diminish the rights or interests of the other Party. Notwithstanding the foregoing, this Section 9.5.2(c) will not apply to Joint Patents that are Product-Specific Patents or Licensed Product Patents or to the infringement of any Joint Patent that is a Isis Core Technology Patent by a Third Party product that [**] encoding apoB, each of which will be governed by Section 9.5.2(a) (Genzyme First Right to Enforce) above.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

9.5.3. Election Not to Enforce.

(a) Isis Second Right. In the event that Genzyme elects not to take action pursuant to Section 9.5.2(a) (Genzyme First Right to Enforce), Genzyme will so notify Isis in writing of its intention within ninety (90) days of Genzyme’s notice of such infringement activities to enable Isis to meet any deadlines by which an action must be taken to establish or preserve any enforcement rights, and Isis will have the right, but not the obligation, to take any such reasonable measures to stop such infringing activities by such alleged infringer. Notwithstanding the foregoing, Genzyme will have the exclusive right to bring actions with respect to infringement of Product-Specific Patents or Licensed Product Patent. Accordingly, Genzyme will not be required to notify Isis with respect to any election not to take action with respect to a Product-Specific Patent, and Isis will have no right to take reasonable measure to stop any infringement of Product-Specific Patents.

(b) Genzyme Second Right. In the event that Isis elects not to take action pursuant to Section 9.5.2(b) (Isis First Right to Enforce), Isis will so notify Genzyme in writing of its intention within ninety (90) days of Isis’ notice of such infringement activities to enable Genzyme to meet any deadlines by which an action must be taken to establish or preserve any enforcement rights, and Genzyme will have the right, but not the obligation, to take any such reasonable measures to stop any such infringing activities that involves a product that causes the [**]. If Genzyme desires to assert an Isis Core Technology Patent pursuant to this Section 9.5.3(b) and the infringing product is also Covered by a Product-Specific Patent, then Genzyme will assert both the Product-Specific Patent and the Isis Core Technology Patent, unless it obtains Isis’ written consent to assert only the Isis Core Technology Patent.

(c) Due Consideration. In any event, if one Party has elected not to take action pursuant to Section 9.5.2 (Right to Enforce), then it will explain its reasons for such decision to the other Party, and the other Party will consider these reasons in good faith prior to determining whether to exercise its second right to take action.

9.5.4. Procedures and Expenses.

(a) The Party having the right to initiate any infringement suit under Section 9.5.2 (Rights to Enforce) or Section 9.5.3 (Election Not to Enforce) above will have the sole and exclusive right to select counsel for any such suit and will pay all expenses of the suit, including attorneys’ fees and court costs and reimbursement of the other Party’s reasonable out-of-pocket expenses in rendering assistance requested by the initiating Party. If required under Applicable Law in order for the initiating Party to initiate and/or maintain such suit, or if either Party is unable to initiate or prosecute such suit solely in its own name or it is otherwise advisable to obtain an effective legal remedy, in each case,

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

the other Party will join as a party to the suit and will execute and cause its Affiliates to execute all documents necessary for the initiating Party to initiate litigation to prosecute and maintain such action. In addition, at the initiating Party’s request, the other Party will provide reasonable assistance to the initiating Party in connection with an infringement suit at no charge to the initiating Party except for reimbursement by the initiating Party of reasonable out-of-pocket expenses incurred in rendering such assistance. The non-initiating Party will have the right to participate and be represented in any such suit by its own counsel at its own expense.

(b) If the Parties have mutually agreed that a Party should initiate an infringement action or take such other reasonable measures it deems appropriate to stop infringing activities under Section 9.5.2 (Rights to Enforce) or Section 9.5.3 (Election Not to Enforce), then any expenses incurred by such Party to take such action will be included in Program Costs.

9.5.5. Recoveries. If the Parties obtain from a Third Party infringer, in connection with such suit, any damages, license fees, royalties or other compensation (including any amount received in settlement of such litigation), such amounts will be allocated as follows:

(a) If the Parties mutually agreed that such Third Party infringer should be pursued under Section 9.5.2 (Rights to Enforce) or Section 9.5.3 (Election Not to Enforce) and the expenses incurred in connection with such action were included in Program Costs, then any amounts recovered by either Party will be included as Net Revenues. In such case, the Party pursuing the Third Party infringer under Section 9.5.2 or 9.5.3 will bear all payments awarded against or agreed to be paid by such Party pursuant to such action, including any costs or expenses incurred that exceed the amounts recovered by such Party, but such payments, costs and expenses will be included as Program Costs.

(b) If the Parties did not mutually agree that such Third Party infringer should be pursued under Section 9.5.2 (Rights to Enforce) or Section 9.5.3 (Election Not to Enforce) and the expenses incurred in connection with such action were not included in Program Costs, then any amounts recovered by either Party will be used to reimburse the Parties for their reasonable costs and expenses, including attorneys’ fees incurred in making such recovery (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses), with any remainder to be retained by the Party initiating action under Section 9.5.2 (Rights to Enforce) or Section 9.5.3 (Election Not to Enforce). In such case, such initiating Party will bear all payments awarded against or agreed to be paid by such Party pursuant to such action, including any costs or expenses incurred that exceed the amounts recovered by such Party, and such payments will not be included as Program Costs.

9.6. Claimed Infringement of Third Party Rights.

9.6.1. Notice. In the event that a Third Party at any time provides written notice of a claim to, or brings an action, suit or proceeding against, any Party, or any of such Party’s respective Affiliates or sublicensees, claiming infringement of its patent rights or unauthorized use or misappropriation of its know-how, based upon the development, manufacture or commercialization of the Product in the Territory (“Infringement Claim”), such Party will promptly notify the other Party of the Infringement Claim or the commencement of such action, suit or proceeding, enclosing a copy of the Infringement Claim and all papers served. Each Party agrees to make available to the other Party its advice and counsel regarding the technical merits of any such claim at no cost to the other Party and to offer reasonable assistance to the other Party at no cost to the other Party.

9.6.2. Defense of Infringement Claim; Declaratory Judgment Actions.

(a) Genzyme will have the first right, but not the obligation, to control the defense of any Infringement Claim brought against either Party or any of its Affiliates or sublicensees arising out of the development, manufacture or commercialization of the Product in the Territory. Isis will have the second right, but not the obligation to control the defense of an Infringement Claim in the event Genzyme fails to exercise its right to assume such defense within thirty (30) days following written notice from the other Party of such Infringement Claim. In addition, if applicable prior to the initiation of an Infringement Claim, Genzyme will have the exclusive right, but not the obligation, to bring a declaratory judgment action relating to any Patent that a Third Party has alleged is infringed by the development, manufacture or commercialization of the Product in the Territory. Genzyme will not settle any such claims or suits in a manner that admits the invalidity or unenforceability of any Isis Core Technology Patent or Isis Manufacturing and Analytical Patent or that agrees to any injunction or other equitable remedy binding Isis without obtaining the prior written consent of Isis. Similarly, Isis will not settle any such claims or suits in a manner that admits the invalidity or unenforceability of any Product-Specific Patent or Licensed Product Patent or that agrees to any injunction or other equitable remedy binding Genzyme without obtaining the prior written consent of Genzyme. All litigation costs and expenses incurred in connection with such Infringement Claim or declaratory judgment action, and all damages, payments and other amounts awarded against, or payable by, either Party, including under any settlement with such Third Party, will be included as Program Costs.

(b) The Party controlling the defense of an Infringement Claim or bringing such declaratory judgment action will have the sole and exclusive right to select counsel for any Infringement Claim; provided, however, that it will consult with the other Party with respect to selection of counsel for such defense. The Party controlling the defense of an Infringement Claim or bringing such declaratory judgment action will keep the other Party informed, and will from time to time

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

consult with the other party regarding the status of any such claims and will provide the other party with copies of all documents filed in, and all written communications relating to, any suit brought in connection with such claims. The other Party will also have the right to participate and be represented in any such claim or related suit, at its own expense.

9.6.3. Other Challenges. If the JPC determines (or if after the JPC disbands, the Parties mutually agree) that a Patent owned by a Third Party is or could potentially or arguably be infringed by the development, manufacture or commercialization of the Product in the Territory, then the Parties will discuss the matter and agree upon a strategy relating to such Third Party Patent; provided, however, that if the Parties fail to agree upon such a strategy, then subject to Section 9.3 (Filing, Prosecution and Maintenance of Patents) and Section 9.5 (Enforcement of Patents and Know-How), Genzyme will determine the appropriate strategy in its reasonable discretion. If, consistent with such strategy, either or both Parties challenge such Third Party Patent through opposition, re-examination, nullity or revocation proceeding, or other available administrative mechanism, then all costs and expenses incurred by the Parties in connection with such challenge will be included as Program Costs.

9.7. Other Infringement Resolutions. In the event of a dispute or potential dispute that has not ripened into a demand, claim or suit of the types described in Section 9.5 (Enforcement of Patents and Know-How) and Section 9.6 (Claimed Infringement of Third Party Rights) (e.g., actions seeking declaratory judgments and revocation proceedings), the same principles governing control of the resolution of the dispute, consent to settlements of the dispute, and implementation of the settlement of the dispute (including sharing in and allocating the payment or receipt of damages, license fees, royalties and other compensation) will apply. Each Party will immediately notify the other Party of any certification of which it becomes aware filed pursuant to 21 U.S.C. § 355(b)(2)(A) or § 355(j)(2)(A)(vii) (or any amendment or successor statute thereto) or declaratory judgment action filed by a Third Party claiming that a Product-Specific Patent, Licensed Product Patent, Special Isis Core Technology Patent is invalid or that infringement of such Patent will not arise from the development, manufacture, use or sale of any product by a Third Party. The provisions of Section 9.5 (Enforcement of Patents and Know-How) will thereafter apply as if such Third Party were an infringer or suspected infringer; provided, however, that in the event that Genzyme elects not to take action, Genzyme will so notify Isis in writing of its intention within ten (10) days of Genzyme’s notice of such infringement activities to enable Isis to meet any deadlines by which an action must be taken to establish or preserve any enforcement rights.

9.8. Patent Term Extensions. The Parties will use commercially reasonable efforts to obtain all available supplementary protection certificates (“SPC”) and other extensions of Licensed Patents and Product-Specific Patents (including those available under the Hatch-Waxman Act). The Parties will cooperate with each other in gaining patent term restorations, extensions and/or SPCs wherever applicable to Licensed Patents and Product-Specific Patents. If more than one patent is eligible for extension or patent term

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

restoration, Genzyme will determine, in its sole discretion, a strategy that will be designed to maximize patent protection and commercial value for the Product, and the Parties will seek patent term restorations in accordance with that strategy. The Party who is responsible under this Agreement for prosecution and maintenance of the relevant Patent will make the filings for such extensions and certificates as directed by Genzyme. Each Party will execute such authorizations and other documents and take such other actions as may be reasonably requested by the other Party to obtain such extensions.

9.9. Orange Book Listings. At least fifteen (15) business days prior to the expiration of the time period under 21 C.F.R. § 314.53, or any successor regulation, for submitting patent information pertaining to Product-Specific Patents, Licensed Product Patents, Isis Core Technology Patents or Isis Manufacturing and Analytical Patents with respect to the Product, Genzyme will submit to Isis any such draft submission, including any forms such as Form FDA 3542, Form FDA 3542a or any equivalent thereof, for Isis’ review and comment. Genzyme will consider in good faith any comments made by Isis pursuant to this Section. In the event that the Parties, after good faith discussions, cannot agree with respect to any decision to be made concerning such submission of patent information, Genzyme will make such decision.

9.10. Cooperative Research and Technology Act Acknowledgement. The Parties acknowledge and agree that this Agreement is a joint research agreement for the purposes of Section 35 U.S.C. 103(c).

9.11. Common Interest. All information exchanged between the Parties representatives regarding the preparation, filing, prosecution, maintenance, or enforcement of the Product-Specific Patents and Licensed Patents will be deemed Confidential Information. In addition, the Parties acknowledge and agree that, with regard to such preparation, filing, prosecution, maintenance, and enforcement of the Product-Specific Patents and Licensed Patents, the interests of the Parties as collaborators and licensor and licensee are to obtain the strongest patent protection possible, and as such, are aligned and are legal in nature. The Parties agree and acknowledge that they have not waived, and nothing in this Agreement constitutes a waiver of, any legal privilege concerning the Product-Specific Patents and the Licensed Patents, including privilege under the common interest doctrine and similar or related doctrines.

9.12. Product Trademarks. Genzyme will select and own the Product Trademarks for the Product and will be solely responsible for applying for and maintaining registrations the Product Trademarks in the Territory (including payment of costs associated therewith), and all goodwill associated therewith will inure to the benefit of Genzyme. All costs incurred by Genzyme to apply for and maintain Product Trademarks, will be included as Program Costs. Genzyme will assume full responsibility, at its sole cost and expense, for any infringement of a Product Trademark by a Third Party, and will defend and indemnify Isis for and against any claims of infringement of the rights of a Third Party by the use of a Product Trademark in connection with the Product in accordance with Section 10.3 (Indemnification).

Genzyme will indemnify, hold harmless, and defend Isis, its Affiliates, and their respective directors, officers, employees and agents (“Isis Indemnitees”) from and against any and all action, losses, liabilities, damages, costs, fees and expenses (including reasonable attorneys’ fees) arising from a claim, suit, proceeding or other action of a Third Party (collectively, “Losses”) arising out of or resulting from, (a) any breach of, or inaccuracy in, any representation or warranty made by Genzyme in this Agreement, or any breach or violation of any covenant or agreement of Genzyme in or pursuant to this Agreement, and (b) the gross negligence or willful misconduct by or of Genzyme, its Affiliates and their respective directors, officers, employees and agents. This indemnification excludes Losses arising out of Third Party Infringement Claims resulting from Genzyme’s exercise in accordance with the terms of this Agreement of any intellectual property rights granted by Isis hereunder, including Genzyme’s exercise of its rights under the Product-Specific Patents. Furthermore, Genzyme will have no obligation to indemnify the Isis Indemnitees to the extent that the Losses arise out of or result from, directly or indirectly, any breach of, or inaccuracy in, any representation or warranty made by Isis in this Agreement, or any breach or violation of any covenant or agreement of Isis in or pursuant to this Agreement, or the negligence or willful misconduct by or of any of the Isis Indemnitees.

10.3.2. Indemnification by Isis. Isis will indemnify, hold harmless, and defend Genzyme, its Affiliates and their respective directors, officers, employees and agents (“Genzyme Indemnitees”) from and against any and all Losses arising out of or resulting from, (a) any breach of, or inaccuracy in, any representation or warranty made by Isis in this Agreement, or any breach or violation of any covenant or agreement of Isis in or pursuant to this Agreement, (b) actions taken by Isis with respect to Mipomersen, the Product, the Licensed IP or the Product-Specific Patents prior to the Execution Date, and (c) the gross negligence or willful misconduct by Isis, its Affiliates, and their respective directors, officers, employees and agents.

agreement of Genzyme in or pursuant to this Agreement, or the negligence or willful misconduct by or of any of the Genzyme Indemnitees.

10.3.3. Special Indemnification for Manufacturing Defects. Each Party will indemnify, hold harmless, and defend the other Party and its Affiliates and their respective directors, officers, employees and agents from and against any and all Losses arising out of or resulting from product liability claims resulting from the failure of any API or Product manufactured by such Party (or a Third Party on behalf of such Party) to conform to the applicable specifications or any failure of such Party (or a Third Party on behalf of such Party) to meet the standards of cGMP for the API or Product. Neither Party will have any obligation to indemnify the other Party and its related indemnitees to the extent that the Losses arise out of or result from, directly or indirectly, any breach of, or inaccuracy in, any representation or warranty made by the other Party in this Agreement, or any breach or violation of any covenant or agreement of the other Party in or pursuant to this Agreement, or the gross negligence or willful misconduct by or of any of the other Party or its related indemnitees. Notwithstanding the foregoing, the indemnification obligations of each Party set forth in this Section 10.3.3 (Special Indemnification for Manufacturing Defects) will only apply to the extent that there would be a Net Loss if such Damages were included in Program Costs in the applicable calendar year. In other words, the manufacturing Party will be required to indemnity the other Party under this Section 10.3.3 only to the extent there are insufficient Net Revenue in the applicable calendar year to permit such Damages to be fully credited as Program Costs.

10.3.4. Damages that are Program Costs. The indemnification obligations of each Party set forth in Section 10.3.1 (Indemnification by Genzyme) and 10.3.2 (Indemnification by Isis) will exclude any Losses resulting from Damages to the extent that the Indemnitee has been reimbursed for such Damages by virtue of the inclusion of such Damages in Program Costs.

10.3.5. Indemnification Procedure. In the event of any claim, suit, proceeding or action of a Third Party (a “Third Party Claim”) giving rise to an indemnification obligation under this Section 10.3, the person or entity entitled to indemnification under this Section 10.3 (individually, an “Indemnitee”), will promptly notify the Party from whom indemnification is sought (the “Indemnifying Party”), in writing of the Third Party Claim (it being understood and agreed, however, that the failure by an Indemnitee to give notice of a Third Party Claim as provided in this Section 10.3 will not relieve the Indemnifying Party of its indemnification obligation under this Agreement, except and only to the extent that such Indemnifying Party is actually prejudiced as a result of such failure to give notice). The Indemnifying Party will manage and control, at its sole expense, the defense of the claim and its settlement. Within thirty (30) days after delivery of such notification, the Indemnifying Party may, upon written notice to the Indemnitee, assume control of the defense of such Third Party Claim with counsel reasonably satisfactory to the Indemnitee. The Indemnitee may participate therein

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

at its own expense; provided, however, that if the Indemnifying Party assumes control of such defense and the Indemnitee reasonably concludes, based on advise from counsel, that the Indemnifying Party and the Indemnitee have conflicting interests with respect to such Third Party Claim, the Indemnifying Party will be responsible for the reasonable fees and expenses of counsel to the Indemnitee solely in connection therewith; provided further, however, that in no event will the Indemnifying Party be responsible for the fees and expenses of more than one counsel in any one jurisdiction for all Indemnified Parties. If the Indemnifying Party does not assume control of the defense of the Third Party Claim within thirty (30) days after delivery of Indemnitee’s notice of such claim and request for indemnification, the Indemnitee(s) may defend such Third Party Claim. Each Party will keep the other Party advised of the status of such Third Party Claim and the defense thereof, and the Indemnifying Party will consider recommendations made by the other Party with respect thereto. If the Indemnifying Party does assume control of the defense of the Third Party Claim, the Indemnifying Party will not agree to any settlement of such Third Party Claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnitee from all liability with respect thereto or that imposes any liability or obligation on the Indemnitee without the prior written consent of the Indemnitee. The Indemnifying Party will not be obligated to indemnify the Indemnitee(s) for any Third Party Claim settled by the Indemnitee(s) without the Indemnifying Party’s prior written consent, which consent will not be unreasonably withheld, delayed or conditioned.

10.4. Insurance. The parties will obtain by the Execution Date and maintain at all times during the term of this Agreement, Products Liability Insurance, including Clinical Trial coverage, with reputable and financially secure insurance carriers each having an A.M. Best rating of [**] or better, to cover their respective indemnification obligations under Section 10.3 (Indemnification), with limits of not less than [**] dollars [**] per occurrence and [**] dollars [**] in the aggregate. Each party will provide the other with a Certificate of Insurance evidencing this coverage within thirty (30) days after the Execution Date. Genzyme will have the right to maintain self-insurance with respect to all or a part of its insurance obligations under this Section 10.4.

termination.

11.2.2. Termination for Material Breach.

(a) If either Party believes that the other Party is in material breach of this Agreement (other than with respect to Genzyme’s failure to use Commercially Reasonable Efforts under Section 5.2.2 (Performance of the Development Program) or Section 6.1 (Commercialization Responsibilities) or Section 7.3 (Research Efforts), which is governed by Section 11.2.3 below), then the non-breaching Party may deliver notice of such breach to the other Party. In such notice, the non-breaching Party will identify the actions or conduct that it wishes such Party to take for an acceptable and prompt cure of such breach (or will otherwise state its good faith belief that such breach is incurable); provided, however, that such identified actions or conduct will not be binding upon the other Party with respect to the actions that it may need to take to cure such breach. If the breach is curable, the allegedly breaching Party will have ninety (90) days to either cure such breach (except to the extent such breach involves the failure to make a payment when due, which breach must be cured within thirty (30) days following such notice) or, if a cure cannot be reasonably effected within such ninety (90) day period, to deliver to the non-breaching Party a plan for curing such breach which is reasonably sufficient to effect a cure within a reasonable period. If the breaching Party fails to (a) cure such breach within the ninety (90) day or thirty (30) day period, as applicable, or (b) use Commercially Reasonable Efforts to carry out the plan and cure the breach, the non-breaching Party may terminate this Agreement by providing written notice to the breaching Party.

(b) Notwithstanding the foregoing, if the allegedly breaching Party 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 (the “Other Party”) of such dispute within such ninety (90) day period or such other reasonable cure period, as applicable, the Other Party will not have the right to terminate this Agreement in accordance with this Section 11.2.2 unless and until it has been determined in accordance with Article 13 (Dispute Resolution) that this Agreement was materially breached by the allegedly breaching Party and that Party fails to cure such breach within the allowed cure period following such determination. It is understood and acknowledge that during the pendency of 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.

(c) This Section 11.2.2 will be subject to and will not limit the provisions of Section 11.2.3 (Termination by Isis for Failure of Genzyme to Use Commercially Reasonable Efforts) and Section 11.3 (Consequences of Termination).

11.2.3. Termination by Isis for Failure of Genzyme to Use Commercially Reasonable Efforts.

(a) Subject to Sections 11.2.3(b) and 11.2.3(c) below, Isis will have the right to terminate this Agreement on (i) a Major Market Country-by-Major Market Country basis if Genzyme is in material breach of its obligations to use Commercially Reasonable Efforts (A) under Section 5.2.2 (Performance of the Development Program) to develop the Product in such Major Market Country or (B) under Section 6.1 (Commercialization Responsibilities) to commercialize the Product in such Major Market Country and (ii) in its entirety if Genzyme is in material breach of its obligations to use Commercially Reasonable Efforts (A) under Section 5.2.2 (Performance of the Development Program) to develop the Product in all Major Market Countries or (B) under Section 6.1 (Commercialization Responsibilities) to commercialize the Product in all Major Market Countries or (C) under Section 7.3 (Research Efforts) to conduct research activities designed to advance a Product to the stage where it can be developed pursuant to a Development Plan. Notwithstanding the foregoing, the Agreement will not so terminate (in its entirety or in any particular Major Market Country) unless (x) Genzyme is given ninety (90) days prior written notice by Isis of Isis’ intent to terminate, stating the reasons and justification for such termination and recommending steps which Genzyme should take and (y) Genzyme or its Sublicensee has not used good faith Commercially Reasonable Efforts in such Major Market Country(ies) during the ninety (90) day period following such notice to diligently pursue the development and/or commercialization of the Product.

(b) It is understood and acknowledged that if Genzyme (by itself or through its Affiliates or Sublicensees) uses Commercially Reasonable Efforts to research, develop or commercialize a Product in each and every Major Market Country, Genzyme will be deemed to be in compliance with its obligation under Section 5.2.2 (performance of Development Program), Section 6.1 (Commercialization Responsibilities) and Section 7.3 (Research Efforts) to use Commercially Reasonable Efforts to research, develop and commercialize a Product with respect to all countries in the world.

(c) If Genzyme disputes in good faith the existence or materiality of an alleged breach specified in a notice provided by Isis pursuant to Section 11.2.3(a) above, and provides notice to Isis of such dispute within the ninety (90) day period following such notice provided by Isis, Isis will not have the right to terminate this Agreement unless and until the existence of such material breach or failure by Genzyme has been determined in accordance with Article 13 and Genzyme fails to cure such breach within ninety (90) days following such determination. It is understood and acknowledged that during the pendency of 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.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

(d) This Section 11.2.3 and Section 11.3 (Consequences of Termination) set forth Isis’ sole and exclusive remedy for Genzyme’s breach of its obligation to use Commercially Reasonable Efforts under Section 5.2.2 (Performance of the Development Program) or Section 6.1 (Commercialization Responsibilities) or Section 7.3 (Research Efforts).

11.3. Consequences of Termination. The following terms will apply on termination of this Agreement:

11.3.1. Licenses. Upon termination of this Agreement by either Party pursuant to this Article 11, the Product License will terminate and Genzyme, its Affiliates and Sublicensees will cease selling the Product.

11.3.2. Return of Information and Materials. Upon termination of this Agreement by either Party pursuant to this Article 11, the Parties will return (or destroy, as directed by the other Party) all data, files, records and other materials containing or comprising the other Party’s Confidential Information. Notwithstanding the foregoing, the Parties will be permitted to retain one copy of such data, files, records, and other materials for archival purposes.

11.3.3. 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 or expiration. Such termination or expiration will not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement. For clarification, (a) no milestone payments under Section 8.2 (Milestones) and (b) no payments under Section 8.5.2 (Sharing of Net Profits) will be payable by Genzyme following termination of this Agreement, except to the extent that the milestone event was achieved (in the case of milestone payments) or the Net Profits were achieved (in the case of net profit sharing) prior to such termination.

11.3.4. Survival. The following provisions of this Agreement will survive the expiration or termination of the Agreement: Section 6.5 (Safety Reporting), Section 8.8 (Audits and Interim Reviews), Section 9.3.2 (Terms of Sharing Agreement), Section 10.3 (Indemnification), Section 11.3 (Consequences of Termination), Section 11.4 (Remedies for Isis’ Material Breach), Article 12 (Confidentiality), Article 13 (Dispute Resolution), and Article 14 (Miscellaneous).

any Product Trademarks, Genzyme Program Patents and other Patents owned or Controlled by Genzyme as of the date of termination that Cover the Product;

(ii) transfer to Isis, for Isis’ use with respect to the development and commercialization of the Product, any data, results, Regulatory Materials and files in Genzyme’s possession as of the date of termination that relate solely to the Product; and

(iii) re-assign to Isis the Product-Specific Patents assigned to Genzyme pursuant to Section 9.1.1 (Assignment of Product-Specific Patents) using a form of assignment substantially similar to the one attached as Exhibit E hereto (collectively with clauses (i) and (ii) above, the “Reversion”).

(b) Limitation. Isis hereby agrees and acknowledges that it may only use the license granted and the materials transferred pursuant to clauses (a)(i) and (a)(ii) of Section 11.3.5(a) in connection with the development and commercialization of the Product for therapeutic purposes.

(i) In consideration for the rights granted and materials transferred by Genzyme to Isis under Section 11.3.5(a) above, Isis will pay to Genzyme a royalty on Net Revenue as follows: (a) [**] of Net Revenue if the Reversion occurs prior to [**], (b) [**] of Net Revenue if the Reversion occurs after the [**] but prior to the [**] and (c) [**] of Net Revenue if the Reversion occurs after the [**] and at the time of or after the [**].

11.4. Remedies for Isis’ Material Breach.

11.4.1. Termination of Committees and Information Sharing. If Isis materially breaches this Agreement and fails to cure such breach within the time periods provided under Section 11.2.2 (Termination for Material Breach) and Genzyme does not wish to terminate this Agreement in its entirety, then, in addition to any other remedies Genzyme may have under this Agreement or otherwise, Genzyme will have the right to do any or all of the following in Genzyme’s discretion: (a) terminate Isis’ right to participate in the JDC and JPC and any other subcommittees or working groups established pursuant to this Agreement, each of which will be disbanded; (b) terminate the participation of Isis in any ongoing research and development programs and Genzyme’s funding obligations associated therewith, (c) make all decisions required to be made by such committees or the Parties collectively under this Agreement in connection with the development and commercialization of the Product, (d) exclude Isis from all discussions with Regulatory Authorities regarding Isis Products, (e) require Isis to assign to Genzyme all of Isis’ right, title and interests in any IND or other Regulatory Materials then held by Isis pertaining to Products and any agreements with Third Parties related solely to the development or supply of the Product; (f) require Isis to enable Genzyme or a Third Party manufacturer to manufacture clinical and initial commercial quantities of the Product in lieu of Isis, with such transition occurring on a commercially reasonable timetable; (g) terminate Genzyme’s obligation to make further disclosures of Know-How or other information to Isis pursuant to this Agreement (including pursuant to Section 5.4.2 (Transfer from Genzyme to Isis) and Section 6.4 (Isis Safety Database)), other than reports required by Section 8.6 (Periodic Reporting and Reconciliation) and as reasonably required to permit Isis to perform its remaining obligations under this Agreement. In addition, if Isis has not completed the development activities that are its responsibility under this Agreement, then Genzyme may, but will not be obligated to, assume all responsibility for all such development activities that would have otherwise been Isis’ responsibility under the Agreement. Isis will cooperate with the foregoing and provide to Genzyme and its Third Party contractors all Know-How, assistance, assignments and other support reasonably requested to assist Genzyme in assuming complete responsibility for the development and manufacture of the Product in an efficient and orderly manner.

11.4.2. Genzyme’s Right of Setoff. If Isis materially breaches this Agreement and fails to cure such breach within the time periods provided under Section 11.2.2 (Termination for Material Breach) and Genzyme does not wish to terminate this Agreement in its entirety, then, in addition to any other remedies Genzyme may have under this Agreement or otherwise (an “Isis Breach Event”), Genzyme may setoff against any amounts owed to Isis pursuant to Article 8 (Financial Provisions) its good faith estimate of the amount of any losses, damages and expenses incurred by Genzyme as a result of Isis’ breach of this Agreement (the “Setoff Amount”). If Genzyme exercises its setoff right under this Section 11.4.2, Genzyme will provide Isis with a written certificate, signed by Genzyme’s Chief Financial Officer, certifying that the amount setoff by Genzyme represents

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

Genzyme’s good faith estimate of such losses, damages and expenses. Notwithstanding the foregoing, if Isis notifies Genzyme in writing that it disputes Genzyme’s assertion that Isis is in material breach of this Agreement or the amount setoff by Genzyme, then (a) Genzyme will initiate the dispute resolution process set forth in Article 13 (Dispute Resolution), and (b) pending the Parties’ agreement regarding the appropriate setoff (if any) or a determination by the mediator of the proper amount that Genzyme may setoff (if any) in accordance with Section 13.2 (Mediation), Genzyme will pay the Setoff Amount into an interest-bearing escrow account established for the purpose at a bank. If the Parties cannot settle their dispute by mutual agreement, then, in accordance with Section 13.2.2 (Mediation of Setoff Disputes) the mediator will determine (1) the amount (if any) that Genzyme may setoff against future payments to Isis going forward, and (2) whether any portion of the escrow account should be released to Isis. In the event that it is finally determined pursuant to Article 13 (Dispute Resolution) by a court of competent jurisdiction that Genzyme has setoff an amount that exceeds the amount of losses, damages and expenses actually incurred by Genzyme as a result of Isis’ breach of this Agreement, then Genzyme will promptly pay Isis the amount of such excess, plus interest on such amount as provided for in Section 8.10 (Interest on Late Payments), with interest accruing from the time Genzyme applied such excess setoff.

Article 12.
CONFIDENTIALITY; PUBLIC DISCLOSURE

12.1. Non-Disclosure. Genzyme and Isis agree that all information relating to the Licensed IP, the terms and conditions of this Agreement, or any activities conducted in connection with or pursuant to this Agreement and disclosed by either Party in accordance with this Agreement (“Confidential Information”) will be used and disclosed by the receiving Party only to perform its obligations and exercise its rights under this Agreement. Information relating to the development of the Product, the Licensed IP and the terms and conditions of this Agreement will be considered the Confidential Information of both Parties under the Agreement, as if both Parties were receiving Parties. Notwithstanding the foregoing, “Confidential Information” will not include information that the receiving Party can establish:

(a) was already known by the receiving Party (other than under an obligation of confidentiality) at the time of disclosure by the disclosing Party;

(b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party;

(c) became generally available to the public or otherwise part of the public domain after its disclosure or development, as the case may be, other than through any act or omission of the receiving Party or any of its Affiliates;

(d) was disclosed to the receiving Party, other than under an obligation of

confidentiality, by a Third Party who had no obligation to the disclosing Party not to disclose such information to others; or

(e) was independently discovered or developed by or on behalf of the receiving Party without the use of any Confidential Information belonging to the disclosing Party.

12.2. Authorized Disclosure and Use. Notwithstanding the foregoing provisions of Section 12.1, each Party may disclose Confidential Information belonging to the other Party to the extent such disclosure is reasonably necessary to:

(a) prosecute or defend litigation,

(b) comply with applicable governmental laws and regulations (including the rules and regulations of the Securities and Exchange Commission); or

In the event a Party deems it reasonably necessary to disclose Confidential Information belonging to the other Party pursuant to clauses (a), (b) and (c) of this Section 12.2, the disclosing Party will to the extent possible give reasonable advance notice of such disclosure to the other Party and take reasonable measures to ensure confidential treatment of such information. Each Party will promptly notify the other Party upon becoming aware of any misappropriation or unauthorized disclosure or use of the other Party’s Confidential Information.

12.3. Terms of Agreement. The Parties agree that the terms of this Agreement are confidential and will not be disclosed by either Party to any Third Party (except to a Party’s professional advisors, including, without limitation, accountants, financial advisors, and attorneys) without prior written permission of the other Party; provided, however, that (a) either Party may make any filings of this Agreement required by Applicable Law in any country so long as such Party uses its reasonable efforts to obtain confidential treatment for portions of this Agreement as available, consults with the other Party, and permits the other Party to participate, to the greatest extent practicable, in seeking a protective order or other confidential treatment; (b) either Party may disclose this Agreement on a confidential basis to potential Third Party investors or acquirers or, in the case of Genzyme, to potential Sublicensees, in each case in connection with due diligence or similar investigations; and (c) a Party may publicly disclose, without regard to the preceding requirements of this Article 12 (Confidentiality), information that was previously publicly disclosed in compliance with such requirements.

12.4 Public Disclosures.

(a) The Parties have agreed upon, and from time to time will agree upon updates to, a communication strategy document containing detailed substantive messaging and a detailed fact sheet with respect to the development, regulatory

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

Approval process, manufacturing and commercialization of the Product (the “Communications Plan”). The Communication Plan will identify agreed spokespeople according to subject matter and will include a calendar detailing events (investor and medical meetings, earnings dates, etc) and anticipated new Product disclosures warranting press releases, updates to any slide presentation or other communication materials. If the Parties are unable to agree upon the content of a particular disclosure in any update to the Communications Plan, then the Party to whom the Agreement assigns primary responsibility over the subject matter of the disclosure will have the right to decide upon the appropriate content. Accordingly, in the event of such a disagreement, Isis will have the right to decide upon the appropriate disclosure on scientific matters, and Genzyme will have the right to decide upon the appropriate disclosure for pre-clinical and clinical development, regulatory, and commercial matters. If any spokesperson identified in the Communications Plan leaves the employ of a Party or changes roles such that it is no longer appropriate for him or her to serve as a spokesperson, the Party who employs such spokesperson may designate a replacement.

(b) In addition, from time to time the JDC will approve a scientific and medical publication plan (the “Scientific Publication Plan”). The Parties will refrain from making any public communications or disclosures regarding the Product other than those set forth in the Communications Plan or as expressly contemplated by the Scientific Publication Plan. Without limiting the generality of the foregoing, except for the specific disclosures set forth in the Communication Plan or as otherwise expressly contemplated by the Scientific Publication Plan, each Party will refrain from making any public disclosures concerning (i) the status of any Approval, (ii) any application for any Approval, or (iii) any communication with or from any Regulatory Authority. Isis will refer to Genzyme, in its capacity as holder of the IND, NDA or other Approval (as applicable) for the Product, any questions it may receive concerning these matters that call for information beyond that provided in the Communications Plan.

(c) To the extent that either Party proposes to make any public disclosure that deviates from the Communications Plan, it will submit to the other Party an initial draft of any press release, slide presentation or other public communication for review and comment at least five (5) Business Days in advance of such proposed public communication. In such event, each Party will not make any public communication unless and until the Parties revise the Communications Plan in accordance with Section 12.4(a) so as to include the disclosure included in such proposed public communication. For public disclosures that do not deviate from the Communications Plan, each Party will submit to the other Party a draft of any such public communication for review and comment at least forty-eight (48) hours in advance of such public disclosure. Notwithstanding any other provision of this Agreement, however, each Party may at any time make any press release or other public communication as it determines, based upon the advice of counsel, to be necessary to comply with any public disclosure obligations under Applicable Laws (including securities laws), so long as the announcing Party

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

provides the other Party at least some advance notice (which will be at least forty-eight (48) hours whenever possible) regarding the proposed public disclosure. Genzyme may satisfy its notice obligation under this Section 12.4 by emailing and telephoning either Isis’ Chief Executive Officer or Chief Operating Officer, and Isis may satisfy its notice obligation under this Section 12.4 by emailing and telephoning either the Genzyme Senior Vice President, Cardiovascular or the Genzyme Senior Vice President of Corporate Affairs.

(d) Each Party will promptly notify (and provide as much advance notice as possible to) the other of any event materially related to Products (including any regulatory Approval) so that the Parties may, subject to the provisions of subsections (a) and (b) of this Section 12.4, analyze the need to or desirability of publicly disclosing or reporting such event.

(e) In accordance with Section 2.7 (Third Party Agreements), Isis will promptly provide Genzyme with any draft publication relating to the Product submitted to it for review pursuant to any agreement with any Third Party and will exercise its rights under any such agreement to comment on such publication in consultation with and as reasonably requested by Genzyme. Isis will not enter into any agreement after the Execution Date that grants any Third Party the right to make public statements regarding the Product unless the form of such agreement is approved in advance by Genzyme.

(f) Unless otherwise contemplated by the Scientific Publication Plan, Genzyme will serve as the principal point of contact for any Third Party author intending to publish a scientific or medical publication on matters with respect to which Genzyme is assigned primary responsibility under this Agreement, and Isis will serve as the principal point of contact for any such author on matters with respect to which Isis is assigned primary responsibility under this Agreement.

Article 13.
DISPUTE RESOLUTION

13.1. Escalation. In the event of any dispute (other than a dispute regarding the construction, validity or enforcement of either Party’s Patents, which disputes will be resolved pursuant to Section 13.3 (Jurisdiction; Venue; Service of Process)) arising between the Parties relating to, arising out of or in any way connected with this Agreement or any term or condition hereof, or the performance by either Party of its obligations hereunder, whether before or after termination of this Agreement that cannot be resolved by the Parties (each, a “Dispute”), either Party may make a written request that the Dispute be referred for resolution to the chief executive officers of each Party (or their designees) (the “Executives”). Within sixty (60) days of either Party’s written request that the Dispute be referred to the Executives, the Executives will meet in person at a mutually acceptable time and location or by means of telephone or video conference to negotiate a settlement of a Dispute. Each Party may elect to have such Party’s JDC representatives participate in such meeting, if desired, provided that it provides the other Party with reasonable

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

advance notice of such intent so as to enable the other Party to have its JDC representatives also participate in such meeting, if desired. If the Executives fail to resolve the Dispute within such sixty (60) day period and the Dispute concerns any matter that this Agreement delegates to the JDC for determination, then Genzyme will be entitled to resolve the Dispute in its sole discretion. For all other Disputes, in the event that the Executives fail to resolve the Dispute within such sixty (60) day period the Dispute will be referred to mediation under Section 13.2 (Mediation).

13.2. Mediation.

13.2.1. Mediation Generally. If a Dispute cannot be resolved pursuant to Section 13.1 (Escalation), the Parties agree to try in good faith to resolve any such Dispute by non-binding mediation administered by JAMS End Dispute in accordance with its commercial mediation rules. The mediation will be conducted by a single mediator appointed by agreement of the Parties who will have previous judicial experience, or failing such agreement by JAMS End Dispute in accordance with its commercial mediation rules. Unless otherwise mutually agreed upon by the Parties, the mediation proceedings will be conducted in Chicago. The Parties agree that they will share equally the cost of the mediation, including filing and hearing fees, and the cost of the mediator(s). Each Party will bear its own attorneys’ fees and associated costs and expenses.

13.2.2. Mediation of Setoff Dispute.

(a) If Genzyme has exercised its setoff right under Section 11.4.2 (Genzyme’s Right of Setoff) and there is a Dispute regarding whether Isis is in material breach of the Agreement or the proper amount of the setoff that the Parties are unable to resolve in mediation pursuant to Section 13.2.1 (Mediation Generally), then at the completion of such mediation the mediator will decide the following issues, which decision will be binding on the Parties pending final resolution of the Dispute by a court of competent jurisdiction:

(i) Whether the amount placed in escrow by Genzyme pursuant to Section 11.4.2 exceeds the mediator’s objective good faith estimate of the amount of any losses, damages and expenses incurred or likely to be incurred by Genzyme as a result of Isis’ breach of this Agreement;

(ii) What amount (if any) may Genzyme setoff against future payments to Isis under Section 11.4.2, which amount will represent the mediator’s objective good faith estimate of the amount of any losses, damages and expenses incurred or likely to be incurred by Genzyme as a result of Isis’ breach of this Agreement.

(b) If the mediator determines that the amount placed in escrow by Genzyme pursuant to Section 11.4.2 exceeds the mediator’s objective good faith estimate of he amount of any losses, damages and expenses incurred or likely to be incurred

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

by Genzyme as a result of Isis’ breach of this Agreement, the Parties will promptly cause the escrow agent to release to Isis the amount of such excess, plus interest accruing on such amount in the escrow account. The Parties will promptly cause the remaining amount in the account to be returned to Genzyme.

(c) If the mediator determines an appropriate amount that Genzyme may setoff against future payments to Isis under Section 11.4.2, Genzyme may setoff such amount directly, and will not be required to pay such amounts into any escrow account.

(d) The decisions rendered by mediator with respect to the distribution of funds from the escrow account and amount Genzyme may setoff going forward will be binding on the Parties pending resolution of the Dispute by the agreement of the Parties or by a court of competent jurisdiction in accordance with this Agreement.

13.2.3. Legal Remedies. If the Parties fail to reach an amicable agreement pursuant to the non-binding mediation process set forth in Section 13.2 (Mediation) within sixty (60) days of the matter being referred to Mediation, then either Party may pursue a legal remedy in accordance with Section 13.3 (Jurisdiction, Venue, Service of Process).

13.3. Jurisdiction; Venue; Service of Process.

13.3.1. Jurisdiction. Each Party by its execution hereof, (a) hereby irrevocably submits to the exclusive jurisdiction of the United States District Court located in Chicago, Illinois for the purpose of any Dispute arising between the Parties in connection with this Agreement (each, an “Action”) and (b) hereby waives to the extent not prohibited by Applicable Law, and agrees not to assert, by way of motion, as a defense or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named court, that its property is exempt or immune from attachment or execution, that any such Action brought in the above-named court should be dismissed on grounds of forum non conveniens, should be transferred or removed to any court other than the above-named court, or should be stayed by reason of the pendency of some other proceeding in any other court other than the above-named court, or that this Agreement or the subject matter hereof may not be enforced in or by such court and (c) hereby agrees not to commence any such Action other than before the above-named court. Notwithstanding the previous sentence a Party may commence any Action in a court other than the above-named court solely for the purpose of enforcing an order or judgment issued by the above-named court.

13.3.2. Venue. Each Party agrees that for any Action between the Parties arising in whole or in part under or in connection with this Agreement, such Party bring Actions only in the federal courts of the United States of America located in Chicago, Illinois and any appellate court having jurisdiction over appeals from

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

such courts. Each Party further waives any claim and will not assert that venue should properly lie in any other location within the selected jurisdiction.

13.3.3. Service of Process. Each Party hereby agrees that service of process made by registered or certified mail, return receipt requested, at its address specified pursuant to Section 14.5 (Notices), will constitute good and valid service of process in any such Action and (c) waives and agrees not to assert (by way of motion, as a defense, or otherwise) in any such Action any claim that service of process made in accordance with clause (a) or (b) does not constitute good and valid service of process.

Article 14.
MISCELLANEOUS

14.1. Change of Control of Isis.

14.1.1. Termination of Committees and Information Sharing. In the event of a Change of Control of Isis, Genzyme will have the right, exercisable by written notice to Isis or its successor in interest within ninety (90) days of the public announcement of the completion of such Change of Control, to do any or all of the following in Genzyme’s discretion: (a) terminate Isis’ right to participate in the JDC and JPC and any other subcommittees or working groups established pursuant to this Agreement, each of which will be disbanded; (b) terminate the participation of the successor to Isis in any ongoing research and development programs and Genzyme’s funding obligations associated therewith, (c) make all decisions required to be made by such committees or the Parties collectively under this Agreement in connection with the development and commercialization of the Product, (d) exclude Isis or its successor from all discussions with Regulatory Authorities regarding Isis Products, (e) require Isis to assign to Genzyme all of Isis’ right, title and interests in any IND or other Regulatory Materials then held by Isis pertaining to Products and any agreements with Third Parties related to the development or supply of the Product; (f) require Isis to enable Genzyme or a Third Party manufacturer to manufacture clinical and initial commercial quantities of the Product in lieu of Isis, with such transition occurring on a commercially reasonable timetable; (g) terminate Genzyme’s obligation to make further disclosures of Know-How or other information to Isis pursuant to this Agreement (including pursuant to Section 5.4.2 (Transfer from Genzyme to Isis) and Section 6.4 (Isis Safety Database)), other than reports required by Section 8.6 (Periodic Reporting and Reconciliation) and as reasonably required to permit Isis to perform its remaining obligations under this Agreement. In addition, if Isis has not completed the development activities that are its responsibility under this Agreement, then Genzyme may, but will not be obligated to, assume all responsibility for all such development activities and setoff against amounts payable by Genzyme to Isis under this Agreement any expense incurred by Genzyme in connection with such development activities that would have been Isis’ responsibility under the Agreement had the Change of Control not occurred.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

Isis or its successor will cooperate with the foregoing and provide to Genzyme and its Third Party contractors all Know-How, assistance, assignments and other support reasonably requested to assist Genzyme in assuming complete responsibility for the development and manufacture of the Product in an efficient and orderly manner. For purposes of clarification, all Confidential Information of Genzyme in Isis’ or its successor’s possession following Genzyme’s exercise of its rights under this Section 14.1 (Change of Control of Isis) will continue to be subject to all applicable provisions of this Agreement (including, without limitation, Article 12 (Confidentiality).

14.1.2. Purchase of Product Economics. In addition to the rights set forth in Section 14.1.1 (Termination of Committees and Information Sharing), in the event of a Change of Control of Isis, Genzyme will have the right to purchase all of Isis’ rights to receive payments under the Agreement. If Genzyme elects to pursue this right, which election may be made by written notice to Isis or its successor of such election within one hundred and eighty (180) days of the public announcement of the completion of such Change of Control, the Parties will, for a period of sixty (60) days following notice of such election, negotiate in good faith a mutually acceptable fair market value. If the Parties cannot agree on a purchase price, Genzyme will have the option to have a Third Party determine the then-applicable fair market value of Isis’ rights to receive payments under the Agreement (the “Valuation Price”). The Parties will select a mutually agreeable independent investment banking firm of national reputation to ascertain the Valuation Price. If the Parties are unable to agree on such identity of such investment banking firm within a sixty (60) day period, then each Party will select an independent investment banking firm of national reputation and the two designated firms will select a mutually agreeable third investment banking firm who will ascertain the Valuation Price. If Genzyme elects to purchase all of Isis’ rights to receive payments under the Agreement at the price mutually agreed by the Parties or the Valuation Price, as applicable, such purchase will render the rights granted to Genzyme under this Agreement fully-paid and irrevocable, and the Parties will enter into a mutually satisfactory amendment to this Agreement effecting this simultaneously with the payment of such price. If Genzyme does not exercise the right to purchase all of Isis’ rights to receive payments under the Agreement under this Section 14.1.2, the successor’s economic rights under this Agreement will be unchanged.

14.2. Specific Performance. Each Party acknowledges and agrees that, in the event of any breach of this Agreement by such Party or any of its Affiliates, the non-breaching Party may be irreparably and immediately harmed and may not be able to be made whole by monetary damages. Without prejudice to any rights and remedies otherwise available, and notwithstanding Section 13.1 (Dispute Resolution Mechanism), the non-breaching Party will be entitled to seek equitable relief by way of injunction, specific performance or otherwise if the breaching Party or any of its Affiliates breaches any provision of this Agreement.

14.3. Governing Law. This Agreement will be governed by and interpreted in accordance with the laws of the State of New York without reference to its choice of laws or conflicts of laws provisions.

14.4. Waiver; Remedies Cumulative. The failure by either Party to take any action or assert any right hereunder will in no way be construed to be a waiver of such right, nor in any way be deemed to affect the validity of this Agreement or any part hereof, or the right of a Party to thereafter enforce each and every provision of this Agreement. Except as expressly provided in this Agreement, the rights and remedies provided for in this Agreement are cumulative and not exclusive, and the exercise of any right or remedy under this Agreement will in no way prejudice or be construed to be a waiver of any other right or remedy a Party may have under this Agreement or otherwise.

14.5. Notices. Any consent or notice required or permitted to be given or made under this Agreement by one of the Parties hereto to the other will be in writing and delivered by hand or sent by nationally recognized overnight delivery service, prepaid registered or certified air mail, or by facsimile confirmed by prepaid, registered or certified mail letter, and will be deemed to have been properly served to the addressee upon receipt of such written communication, in any event to the following addresses (or any updated address provided to the notifying Party in writing in accordance with this Section 14.5):

FORM OF SUPPLY AGREEMENT

MANUFACTURING AND SUPPLY AGREEMENT

This Manufacturing and Supply Agreement (the “Supply Agreement”) is entered into as of the 24th day of June, 2008 (the “Effective Date”) by and between Isis Pharmaceuticals, Inc. (“Isis”) and Genzyme Corporation (“Genzyme”). Genzyme and Isis may each be referred to herein as a “Party” or together as the “Parties”. Capitalized terms not defined herein will have the meaning given to such terms in the License and Co-Development Agreement between the Parties dated June 24, 2008 (the “Agreement”). The Parties agree as follows:

WHEREAS, the Parties have entered the Agreement to provide for the further development and commercialization of one or more Products, including Mipomersen;

WHEREAS, the Agreement provides that Isis will be responsible for the manufacture of the active pharmaceutical ingredient (API) of Mipomersen (“API”) for the phase II clinical trials, the Pivotal Trial(s) and the initial commercial launch of Mipomersen;

WHEREAS, the Parties agree that the terms of this Supply Agreement will apply to all manufactured lots of API made and supplied under the Agreement and this Supply Agreement.

NOW, THEREFORE in consideration of the premises and mutual covenants herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto agree to this Supply Agreement as follows:

1. Scope; Second Manufacturing Suite – Isis will produce the bulk API for Mipomersen under cGMP conditions and in accordance with the Quality Agreement between the Parties and referencing this Supply Agreement (the “Quality Agreement”), in the amount specified in the applicable Firm Order for use for the phase II clinical trials, the Pivotal Trial(s) and the initial commercial launch of Mipomersen.

Isis will use commercially reasonable efforts to have [**].

2. Supply as of Effective Date. As of the Effective Date, Isis has in its inventory the quantities of API, placebo, drug product and clinical trial material set forth on Exhibit B attached hereto (the “Existing Material”).

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

3. Supply through the end of 2008. After the Execution date until the [**] in 2008, Isis will manufacture and supply the API consistent with the needs of the Development Plan, which are approximately [**] kilograms (the “2008 API”).

4. Supply after 2008; Forecasting Before NDA Filing.

(a) After January 1, 2009 until the NDA Filing under the Agreement, Isis and Genzyme will establish an 8 calendar quarter rolling forecast (the “Clinical Rolling Production Forecast”) that sets forth a good faith estimate of the quantity of API for the Mipomersen Genzyme expects to receive from Isis within the following 8 calendar quarter period. This Clinical Rolling Production Forecast will be updated on the first business day of each subsequent calendar quarter by Genzyme. The first 4 calendar quarters of the Clinical Rolling Production Forecast constitute a firm order (each “Clinical Firm Order”). Genzyme will provide one or more purchase orders for Clinical Firm Orders not previously submitted with each new Clinical Rolling Production Forecast. The fifth (5^th) calendar quarter of any Clinical Rolling Production Forecast shall be binding solely to the extent that Genzyme shall be required to order (and Isis shall only be required to supply) not more than [**]% and not less that [**]% of the API forecast therein once such calendar quarter becomes the first (1^st) calendar quarter for the Clinical Rolling Production Forecast. Quarters 6 through 8 are estimated quantities to be used for planning purposes only. Not later than 30 days after the Effective Date, Genzyme will provide Isis with the first Clinical Rolling Production Forecast, which will initially cover the 8 quarter period beginning January 1, 2009. The quantities set forth in a Clinical Firm Order will be binding on both parties, and Genzyme will be obligated to purchase from Isis, and Isis will be obligated to supply, the specified quantities of API.

(b) Notwithstanding the foregoing, each Clinical Firm Order is subject to the following conditions:

· Isis will not be required to supply during a calendar quarter more than an aggregate of [**] kilograms of API, unless agreed to in advance by Isis and further that the batch size is no larger than [**] kilograms unless agreed to in advance by Isis.

· The minimum order size is [**] kilograms per calendar quarter unless agreed to in advance by Isis.

(c) Isis agrees to use commercially reasonable efforts to supply Genzyme, upon request, with quantities in excess of the quantity restrictions described in this Section 4(b) above.

5. Supply; Forecasting After NDA Filing.

(a) After the NDA Filing under the Agreement, Genzyme will establish an eight (8) calendar quarter rolling forecast (the “Commercial Rolling Production Forecast”) that sets forth a good faith estimate of the quantity of API for the Mipomersen Genzyme expects to receive from Isis within the following eight (8) calendar quarter period. This Commercial Rolling Production Forecast will be updated not later than the first business day of each subsequent calendar quarter by Genzyme. The first [**] calendar quarters of the Commercial Rolling Production Forecast will constitute a firm order (“Commercial Firm Order”). Genzyme will provide one or more purchase orders for Commercial Firm Orders not previously submitted with each new Commercial Rolling Production Forecast. The [**] and [**] calendar quarters of any Commercial Rolling Production Forecast shall be binding solely to the extent that Genzyme shall be required to order (and Isis shall be required to supply) not more than [**]% and not less than [**]% of the API forecast therein once those calendar quarters become the first [**] quarters for the Commercial Rolling Production Forecast. Quarters [**] through [**] are estimated quantities to be used for planning purposes only. Not later than 30 days after the NDA Filing, Genzyme will provide Isis with the first Commercial Rolling Production Forecast. The quantities set forth in a Commercial Firm Order will be binding on both parties, and Genzyme will be obligated to purchase from Isis, and Isis will be obligated to supply, the specified quantities of API. Clinical Firm Orders and Commercial Firm Orders may each be referred to herein as “Firm Orders”.

(b) Notwithstanding the foregoing, each Commercial Firm Order is subject to the following conditions:

· Isis will not be required to supply during a calendar quarter more than an aggregate of 50 kilograms of API, unless agreed to in advance by Isis and further that the batch size is no

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

C-2

larger than [**] kilograms unless agreed to in advance by Isis. The minimum order size is [**] kilograms per order.

(c) Isis agrees to use commercially reasonable efforts to supply Genzyme, upon request, with quantities in excess of the quantity restrictions described in this Section 5(b) above.

6. Delivery

(a) Isis will deliver the Existing Material and the 2008 API as directed by the JDC.

(b) Each order submitted in satisfaction of a Firm Order obligation set forth in Section 4 or 5 above shall set forth Genzyme’s proposed delivery date, which date shall not be less than 90 days after the submission of the order in question. Within 10 business days of receipt of an order from Genzyme, Isis will either (i) confirm Genzyme’s proposed delivery date or (ii) enter into discussions with Genzyme about a mutually agreeable delivery date (each, a “Delivery Date”). Isis will use commercially reasonable efforts to deliver the API ordered in each Firm Order by the applicable Delivery Date (but in any event Isis will deliver the API within thirty (30) days of the Delivery Date); provided, however, that Isis may deliver any quantities requested in a Firm Order thirty (30) days early. Isis will not be required to supply, nor will Genzyme be required to purchase, API in a quantity exceeding the Firm Order. The quantity of API specified in each Firm Order, invoiced and paid for will be the as-is gross mass of the API after lyophilization (i.e. including such amounts of water, impurities, salt, heavy metals, etc not exceeding limits permitted in the Specifications). In addition, so long as Isis supplies the quantity of API specified in the applicable Firm Order for Mipomersen within plus or minus [**]%, Isis will be deemed to have satisfied the amount specified in the Firm Order but Genzyme will nonetheless pay for the quantity of API specified in the Firm Order, whether it is less than or greater than the amount ordered.

7. Shortfall

(a) In the event that at any time Isis anticipates that it will be unable to supply at least [**]% (as permitted by Section 6 above) of the quantities of API set forth in an agreed-upon Firm Order in satisfaction of its obligation under Section 4 or 5 for any reason, including without limitation force majeure, Isis will notify Genzyme in writing as soon as possible upon the prediction or occurrence of such non-supply.

(b) If Isis cannot Manufacture as set forth in (a) above, upon written request by Genzyme Isis will transfer to Genzyme all documentation and information, and permit Genzyme to reference and use any regulatory filings, and otherwise fully cooperate with Genzyme to enable Genzyme to make or have made API for use by Genzyme in accordance with the Agreement.

8. Specifications; CofA

(a) For the API supplied by Isis under this Supply Agreement, Isis and Genzyme will mutually agree on the specifications for such API and will attach and/or reference such specifications in the applicable Firm Order (the “Specifications”). If no Specifications are attached to or referenced in a Firm Order the Specifications for the Firm Order will be the same Specifications that applied to the previous Firm Order. The Specifications as of the effective date of this Supply Agreement are attached hereto as Exhibit A and will apply to 2008 API and the API that is part of the Existing Material.

(b) Prior to shipment of API, Isis shall provide Genzyme with a certificate from Isis’ quality assurance department, or Isis’ equivalent thereof, that includes the results of quality control tests that were performed on each batch of API manufactured in accordance with the Specifications and that indicates that the API contained in the shipment: (i) meets the Specifications and (ii) was manufactured in compliance with cGMPs and all other applicable laws and regulations (a “CofA”).

9. API Pricing - The purchase price for API manufactured under this Agreement in 2008 is $[**] per kilogram, except the purchase price for Lot # CA301012-015 will be the [**] $[**] per kilogram and the purchase price set for API manufactured in 2009 under this Section. The purchase price for API manufactured in each subsequent calendar year in the Term shall be determined as follows: In September of each year, starting September of 2008, Isis will provide Genzyme a nonbinding, good faith estimate of the purchase price for API for the following year. By November 15 of each year, starting November 15, 2008, Isis will provide Genzyme the final purchase price (each, a “Purchase Price”) applicable to the manufacture and supply of API scheduled for delivery in the following year. Such Purchase Prices will be binding on both Parties; provided, however, that such price will (i) not exceed $[**] per kilogram of API and (ii) represent Isis’ good faith estimate of its fully-burdened cost to manufacture such API. This price includes all direct and indirect costs of manufacturing the API, including the cost of analytical work, raw materials, storing stability and retain samples, and, unless otherwise specifically stated in the applicable Firm Order, all other activities specified in the Specifications; provided, however, this price does not include stability testing, CMC work, process validation or other work to support regulatory filings. All payments are in US Dollars.

10. Terms of Payment –

(a) On the Execution Date, Isis will apply $[**] towards External Development Expenses under Section 8.3.1 of the Agreement for the Existing Material.

(b) For the 2008 API, Genzyme shall not be required to pay for the 2008 API, but rather upon transfer of such 2008 API Isis shall report the purchase price for the 2008 API as its Fully Absorbed Cost of Goods in reports submitted to Genzyme in accordance with Section 8.6 of the Agreement and such Fully Absorbed Cost of Goods shall be credited against Isis’s obligations to fund the first one hundred and twenty-five million ($125 million) in External Development Expenses as contemplated by Section 8.3.1(b) of the Agreement.

(c) Until the earlier of (i) the first calendar quarter in which Net Revenue (as that term is defined in the Agreement) exceeds the aggregate Purchase Price for API in that calendar quarter and (ii) the date Isis has fully satisfied its obligation to fund the first one hundred and twenty-five million dollars ($125 million) of External Development Expenses in accordance with Section 8.3.1(b) of the Agreement, Genzyme shall not be required to pay the Purchase Price for Product ordered and transferred hereunder, but rather Isis shall report such Purchase Price as its Fully Absorbed Cost of Goods in reports submitted to Genzyme in accordance with Section 8.6 of the Agreement and such Fully Absorbed Cost of Goods shall be credited against Isis’s obligations to fund the first one hundred and twenty-five million ($125 million) in External Development Expenses as contemplated by Section 8.3.1(b) of the Agreement.

(d) Once the condition described in either clause (i) or (ii) of Section 10(c) above has been satisfied, then the following payment terms shall apply to Product supplied hereunder:

· A pre-payment of 50% of the Purchase Price from Genzyme is payable in cash upon delivery of the applicable Firm Order.

· The remaining 50% of the Purchase Price is due in cash to Isis by wire transfer or other customary means within 30 days from the date of receipt of invoice, following title transfer from Isis to Genzyme or its designee of the API (in accordance with Section 12 below).

· In addition to the price stated in this Supply Agreement, Genzyme will pay to Isis all taxes and duties (except income tax) imposed upon Isis, in connection with the API and will reimburse Isis for the insurance and freight expenses discussed in Section 12 below.

11. Term – This Supply Agreement will remain in effect as long as Isis and Genzyme mutually agree for Isis to supply Mipomersen API as described in the Agreement.

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

C-4

Genzyme’s Quality Assurance Department authorizing shipment of the applicable Existing Material. Isis will insure against the replacement cost of the Existing Material until title transfers. The Parties will share the Risk of loss related to the Existing Material.

Isis will ship the Existing Material in accordance with the applicable Authorization to Ship letter from Genzyme’s Quality Assurance Department. Isis will pay all freight for such transportation and include such costs as part of Isis’ Fully Absorbed Cost of Goods.

13. Title & Transportation for other API: Title to the API supplied under Section 3, 4 or 5 above will transfer to Genzyme upon the earlier of (i) 15 days following the receipt by Genzyme of the CofA, a copy of the batch record and the QC release testing for the applicable order (unless Genzyme initiates formal dispute resolution regarding the API’s failure to meet the warranty set forth in Section 17), (ii) EXW (Incoterms 2000) Isis’ facility following Isis’ receipt of an Authorization to Ship letter from the Genzyme’s Quality Assurance Department authorizing shipment of the applicable API order, and (iii) the date pursuant to the dispute resolution it is determined that the API did meet the warranty set forth in Section 17. Isis will insure against the replacement cost of the API until title transfers. Risk of loss passes simultaneously with the title. Isis may deliver the applicable invoice to Genzyme for API contemporaneously with title transfer.

Isis will ship the API to Genzyme EXW (Incoterms 2000) upon the earlier of (i) the date such API is released by Isis’ Quality Assurance Department and accepted by Genzyme’s Quality Assurance Department via an Authorization to Ship letter, and (ii) 60 days following title transfer of such API. Transportation arrangements will be made by Isis as specified by Genzyme. Isis will pay all freight for such transportation and add such costs to the invoice as a separate line item.

14. Intellectual Property: The ownership and treatment of any intellectual property generated in the course of Isis’ performance of this Supply Agreement will be governed by the Agreement.

15. CMC Work, Regulatory Support & Stability Testing –Genzyme will be responsible for all CMC work and regulatory filings associated with the API and drug product. Isis will not be responsible for CMC work, process validation or other work to support regulatory filings under this Supply Agreement. If Genzyme wishes to engage Isis to perform such work the Parties will mutually agree upon an appropriate plan and budget for executing such work.

Isis will manage the stability testing of any API manufactured under this Supply Agreement per Isis’ current stability protocol (whether performed by Isis or an independent contractor). If performed by Isis, the price for the stability testing of the API will be $7,000 per time point per lot of API. If performed by a contractor, the price fro the stability testing of the API will be the price charged by the contractor. In either case, the price for the stability testing will be treated as Program Costs under the Agreement.

16. Hazards; Risk Sharing

If Isis encounters any difficulties or hazards during the manufacturing of a batch of API such that the delivery of API to Genzyme from that batch would constitute a breach of this Supply Agreement (including but not limited to the failure of such API to conform to the warranty set forth in Section 17), Isis will use commercially reasonable efforts to manufacture a replacement batch of API, such that Genzyme receives such API as close to the originally-scheduled delivery date as possible.

If the difficulty or hazard that causes the breach was not caused by Isis’ gross negligence, the cost of the manufacture of the replacement batch will be shared by Genzyme and Isis as follows: Isis will be responsible for the [**] components for such batch of API; and, to the extent not reimbursable under Isis’ insurance policies, Genzyme will be responsible for the [**] component and [**] expenses. In any year in which Net Profit is achieved under the Agreement, [**] components (and Genzyme’s expenses for [**] and [**] expenses) for such replacement batch of API will be included as Program Costs under the Agreement with [**] included using the methodology referred to in the definition of Fully Absorbed Cost of Goods in the Agreement. For purposes of clarity and assuming none of the loss is covered

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

C-5

by Isis’ insurance, the total price payable for such API will equal the price for such API originally specified above under Section 9 above or quoted in the Firm Order plus the [**] component and [**] expenses attributable to such replacement batch. However, if the difficulty or hazard that causes the breach was caused by Isis’ gross negligence, the cost of the manufacture of the replacement batch will be solely Isis’ responsibility and the price payable upon delivery of such API will equal the price for such API originally quoted in the Firm Order without any additional costs or expenses required to produce the replacement batch.

17. Limited Warranty: SUBJECT TO THE LIMITATIONS OF PARAGRAPHS, 18, 19 AND 21, Isis warrants, with respect to all the API, that, at the time of delivery, any API supplied by Isis will (a) meet the Specifications; (b) meet the standards of cGMP (for the API) and the requirements set forth in the Quality Agreement and (c) be conveyed with good title, free from any lawful security interest, lien or encumbrance.

18.
