The other Party will cooperate with the Designated Regulatory Party, at its reasonable request, with respect to any regulatory matters for which the Designated Regulatory Party is responsible. Unless exigent action is required with respect to such Regulatory Filing or material communication, the Designated Regulatory Party will provide the other Party with copies of Key Regulatory Filings prior to submission within a reasonable amount of time (but not less than five (5) business days) to allow such Party to review and comment on such Key Regulatory Filings, and the Designated Regulatory Party will consider all comments and proposed revisions from the other Party in good faith prior to submission (but in the event of a disagreement between the Parties with respect to such comments and proposed revisions, (i) if the Development Lead’s determination is consistent with the then-current Development Plan, then the Development Lead’s determination shall prevail, and (ii) if the Development Lead’s determination is not consistent with the then-current Development Plan, then such matter shall be escalated to the JSC for review (and if a Critical Matter, further escalated to the CRC)). The Designated Regulatory Party will consult with the other Party regarding, and keep the other Party informed of, the status of the preparation of all Regulatory Filings it submits, Governmental Authority review of any such Regulatory Filings, and all Regulatory Approvals that it obtains with respect to a Product. Upon request of the other Party, the Designated Regulatory Party will provide to the other Party copies of all final Regulatory Filings it submits.

Regulatory Meetings. The Designated Regulatory Party will consult with the other Party reasonably in advance of the date of any anticipated meeting with a Governmental Authority and will consider any timely recommendations made by the other Party in preparation for such meeting. Upon the request of the other Party, the Designated Regulatory Party will permit the other Party to attend particular meetings between the Designated Regulatory Party and the applicable Governmental Authority. The Designated Regulatory Party will request that the applicable Governmental Authority allow at least one (1) representative of the other Party to attend, solely as an observer, such meetings; provided, that the foregoing will not apply to informal meetings or unscheduled teleconferences or meetings or teleconferences otherwise intended by the Governmental Authority to be between it and the Designated Regulatory Party’s

representatives only. The other Party will strictly follow the Designated Regulatory Party’s instructions with respect to any meeting which it attends, and will not discuss the contents of any such meeting with any Governmental Authority except as required by Applicable Law or authorized by the Designated Regulatory Party in writing.

Manufacturing Matters. In order to assist the Designated Regulatory Party, the Manufacturing Lead will prepare [*] in English for the relevant Product, and the Designated Regulatory Party will modify as appropriate such module for use in Regulatory Filings in the Collaboration Territory. The Manufacturing Lead will have the option, in order to protect proprietary manufacturing information, to take over operational responsibility from the Designated Regulatory Party for some or all correspondence and for specified official communications, including the preparation and submission of all Regulatory Filings required to be filed with any Governmental Authority in the Collaboration Territory with respect to the manufacture of a Product (except to the extent such transfer of operational responsibility is prohibited by Applicable Law or a Governmental Authority). With respect to any such correspondence and communication, each Party will promptly provide the other with copies of material written correspondence as reasonably necessary to permit each Party to comply with its relevant regulatory obligations or as otherwise reasonably requested; provided, that the Manufacturing Lead will not be required to disclose proprietary or competitively sensitive information unless such disclosure is required by Applicable Law.

Ownership of Regulatory Filings and Regulatory Approvals. The Development Lead for a Product will own all right, title and interest in and to any and all Regulatory Filings and Regulatory Approvals directed to such Product and all such Regulatory Filings and Regulatory Approvals will be held in the name of the Development Lead, and the other Party will execute all documents and take all actions as are reasonably requested by the Development Lead to vest such title in the Development Lead, subject to Section 3.1.6 (Ownership of Development and Safety Data) and Section 3.2.4 (Manufacturing Matters). The Development Lead hereby grants to the other Party a non-exclusive, non-transferable (except in connection with a permitted assignment, sublicense or subcontract) “right of reference” (as defined in 21 C.F.R. §314.3(b)) with respect to such Regulatory Filings and Regulatory Approvals solely as necessary for the other Party, if such other Party is the Designated Regulatory Party, to prepare, submit and maintain Regulatory Filings for which it is responsible or as otherwise necessary to perform its obligations hereunder or to comply with Applicable Law.

Brand Security and Anti-Counterfeiting. The Parties will establish contacts for communication regarding brand security issues and will each reasonably cooperate with the other with respect thereto.

Product Complaints, Recalls and Returns. The Parties’ rights and obligations with respect to nonconformance, recalls and returns of Products will be governed by the applicable Quality Agreement.

The Development Lead will, in accordance with Applicable Law and its internal policies, publish the results or summaries of clinical trials relating to a Product on a clinical trial register maintained by it and the protocols of clinical trials relating to such Product on ▇▇▇.▇▇▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇ (or an equivalent register, or as otherwise required by Applicable Law or such Party’s policies). The other Party will have the right to publish results or summaries (in the identical form as published by the Development Lead) if the Development Lead has already published in accordance with the foregoing sentence, or the applicable JPT approves such publication. The Parties will cooperate to establish timelines and procedures for JPT review of publications and presentations.

Sharing of Data and Know-How.

Generally. Each Party shall (and shall cause its Affiliates to) reasonably cooperate with the other Party to promptly share and provide access to (i) all clinical trial data and results within the Program Intellectual Property, and (ii) such other Know-How within the Product Intellectual Property as is reasonably necessary for the other Party to exercise its rights or fulfill its obligations under this Agreement. The JSC may establish reasonable policies to effectuate such exchange of data and Know-How between the Parties.

Manufacturing Know-How. For clarity, except as provided in Section 3.2.4 (Manufacturing Matters) above, the Manufacturing Lead shall not be obligated to share with the other Party or provide the other Party access to Know-How related to the manufacture of a Product unless and until such Party becomes the Manufacturing Lead with respect to such aspect of manufacturing of such Product, in which case the Manufacturing Lead shall promptly provide the other Party with access to such manufacturing Know-How within the Product Intellectual Property as is reasonably necessary for such Party to fulfill its obligations as Manufacturing Lead with respect to such Product. All such transfer of manufacturing Know-How shall be overseen and facilitated by the JPT for the applicable Product.

Allocation of Manufacturing Responsibility. Amgen will be responsible for the supply of clinical and commercial product for AMG827. Amgen will be responsible for the initial supply of clinical product for all other Products (the “Early Stage Programs”). Amgen will elect at least [*] days prior to the initiation of the first [*] for each Early Stage Program whether or not to continue supplying later stage clinical material and commercial material for such Early Stage Program itself or through a contract manufacturing organization. If Amgen elects not to do so, then Partner will have [*] days to elect to

manufacture such later stage clinical material and commercial material for such Early Stage Program (including conducting any process development work related thereto). If neither Party elects to manufacture later stage clinical material and commercial material for such Early Stage Program, then the Parties will mutually agree upon a Third Party manufacturer to conduct process development and clinical and commercial manufacturing. In any event, Amgen will continue to supply clinical material (in the form that exists prior to such election) until such time as Partner or such Third Party manufacturer completes commercial process development and begins to supply such later stage clinical material; provided, that, if Partner elects to manufacture later stage clinical material and commercial material, then Partner will promptly and diligently undertake such efforts as are necessary to assume responsibility for such activities.

Manufacturing Lead. The Party that actually manufactures (itself or through a designee) a specific Product will be the “Manufacturing Lead” for such manufactured Product. For clarity, one Party may be the Manufacturing Lead for drug substance and the other Party may be the Manufacturing Lead for drug product. Subject to Section 4.6 (Shortage; Allocation), the Manufacturing Lead will use Commercially Reasonable Efforts to supply Product in a manner sufficient to fulfill demand for the Product in the Collaboration Territory. Additionally, if Partner elects to become the Manufacturing Lead for a Product in accordance with Section 4.1 (Allocation of Manufacturing Responsibility) or is otherwise appointed the Manufacturing Lead by the CRC, the Parties will, with respect to Products manufactured by Partner, negotiate in good faith supplements to the definitions of Manufacturing Standard Costs and Manufacturing Actual Costs in order to make such definitions consistent, on a GAAP or IFRS basis (as applicable), with the manner in which Partner accounts for its other products.

[*] Updates. The JSC will review and approve updates to the Operations Budgets prior to [*]. Additionally, after Technical Feasibility has been achieved with respect to a Product, on a quarterly basis the Manufacturing Lead will inform the JSC of any expected decrease in [*] that is expected to result in [*]. At the request of the other Party, the Manufacturing Lead will inform the other Party of [*] and will discuss with the other Party [*] with respect thereto. The Manufacturing Lead will have the sole right to determine which of its manufacturing sites will be used to manufacture a Product and may transfer the manufacturing of such Product from one site to another, so long as such transfer would not reasonably be likely to have a material adverse effect on the continued supply of such Product.

Distribution. Amgen will be solely responsible for the distribution of Products in the Amgen Distribution Countries. Partner will be solely responsible for the distribution of Products in all other countries in the Collaboration Territory. The Party that actually distributes Products in a particular country will be deemed the “Distribution Party” for such country. The Manufacturing Lead of drug product will supply Products for commercial use in labeled, finished form (unless otherwise agreed to by the JSC) to the other Party for distribution in the countries for which the non-Manufacturing Lead for drug product has been allocated distribution responsibility. The non-Manufacturing Lead will reimburse the Manufacturing Lead for such Product at the Manufacturing Lead’s Manufacturing Actual Cost upon delivery

of such Product to the non-Manufacturing Lead. Such reimbursement will not be included in the calculation of Collaboration Profit (Loss) under Section 7.2 (Profit/Expense Sharing), but rather the non-Manufacturing Lead will be entitled to include such payment as part of Amgen Costs or Partner Costs, as applicable, upon sale of such Product to a Third Party.

Quality and Safety Agreements. Concurrently with the execution of this Agreement, the Parties have entered into the Quality Agreement with respect to the supply of Products by Amgen to Partner for clinical use. Within ninety (90) days of the Effective Date, the Parties will enter into the Safety Agreement with respect to the supply of Products by Amgen to Partner for clinical use. One year prior to the anticipated first commercial launch of a Product, the Parties will enter into a Quality Agreement with respect to the supply of Products by Amgen to Partner for commercial use and will work in good faith to revise the existing Safety Agreement as necessary. In the event that Partner becomes a Manufacturing Lead for a Product, the Parties will enter into a Quality Agreement with respect thereto and will work in good faith to revise the existing Safety Agreement as necessary.

Shortage; Allocation. In the event that the Manufacturing Lead reasonably believes that it will not be able to supply requirements for a Product in accordance with a mutually agreed upon supply forecast, the Manufacturing Lead shall provide prompt written notice to the other Party thereof. If the Manufacturing Lead actually cannot supply a Product in accordance with such mutually agreed upon supply requirements, then the Manufacturing Lead will undertake to allocate the manufacturing of Products with its other products so as to not [*]. For clarity, if the Manufacturing Lead cannot actually supply requirements for a Product in accordance with a mutually agreed upon supply forecast, the Manufacturing Lead will reasonably allocate its manufacturing capacity over all its products in the following order of prioritization: (a) to [*]; (b) to [*]; (c) to [*]; and (d) to [*].

Allocation of Commercial Responsibility. The JSC will (i) allocate commercial activities to Amgen or Partner on a Product-by-Product basis and country-specific or activity-specific basis, and (ii) determine whether operational responsibility for any such activity should be transferred from Partner to Amgen or vice versa. Allocations of commercial operational responsibility for countries and regions may be set forth in country plans developed by the applicable JPT that are consistent with the allocation of responsibility established by the JSC and the Brand Plan, taking into account the planned launch timing for the relevant country (as such plans may be updated or modified from time-to-time by the applicable JPT, the “Country Plans”). The initial allocation of commercial activities, as well as the guidelines for allocating commercial activities in the future, is as set forth in the Commercial Allocation Schedule.

Commercial Lead. For each Product, one Party will oversee commercialization activities with respect to all indications for such Product in the Collaboration Scope (the “Commercial Lead”). The Commercial Lead for each Product will be as set forth on the Development/Commercial Lead Schedule.

Initial Plans; [*] Updates. An initial Brand Plan for each Product will be approved by the JSC not later than three (3) months after initiation of the first Phase 3 Trial for such Product; provided, that the initial Global Payer Plan and each initial Access and Pricing Plan will be approved by the JSC at such times as the JSC so determines. The JSC will review and approve updates to the Brand Plans and Commercialization Budgets prior to [*].

All Sales by Distribution Party. Only the Distribution Party with respect to a particular Product in a particular country is authorized to sell such Product in such country. The Distribution Party will have the sole right, in such Party’s discretion, to take orders for and returns of, issue credits for, sell, and book sales for, such Product. The non-Distribution Party will promptly forward to the Distribution Party all orders for, and requests to order, such Product. The Distribution Party will have the right to refuse or cancel any order for such Product without liability to the other Party. The non-Distribution Party will not interfere with any agreement of the Distribution Party or any of its Affiliates related to such Product, including contracting for the sale of such Product.

Training. The JPT will establish a process by which the Parties will review, comment on and approve training materials and programs, and training of the Parties’ sales forces for commercialization of the Products will be conducted using only training materials and programs approved in accordance with such process. Each Party will train its respective sales representatives with respect to the promotion of a Product (and update such training from time to time as appropriate) which training will include compliance training as appropriate, all in accordance with the applicable Brand Plan. The Commercial Lead for a Product will own all right, title and interest in the training materials developed hereunder for such Product (except with respect to any Housemarks of the other Party contained therein), and the non-Commercial Lead will execute all documents and take all actions as are reasonably requested by the Commercial Lead to vest title to such training materials in the Commercial Lead.

Information Concerning Products. Each Party will ensure that no claims or representations in respect of a Product or the characteristics thereof are made by or on behalf of it or its Affiliates (by sales force members or otherwise) that have not been approved by the JPT and neither Party will make any claim or representation that does not represent an accurate summary or explanation of the labeling of such Product.

Promotional Materials. The JPT will establish a process by which the Parties will review, comment on and approve all written sales, promotion and advertising materials relating to a Product, and other media and materials used to promote the Products or educate the public regarding an indication treated with a Product (collectively and including translations, “Promotional Materials”). All Promotional Materials will be produced by the applicable Commercial Lead in accordance with the Brand Plan and such process and any use thereof by the non-Commercial Lead will be subject to prior approval of the Commercial Lead. All Promotional Materials will include, to the extent permitted by Applicable Law, the Amgen Housemarks and the Partner Housemarks. Unless otherwise determined by the

applicable JPT, the Commercial Lead will be responsible for the printing and delivery to the other Party of Promotional Materials for use in such other Party’s Detailing obligations hereunder. Other than a Party’s use and distribution of Promotional Materials that are approved in accordance with the foregoing process and used and distributed in connection with a Party’s Detailing of a Product, neither Party will produce or modify (other than as concepts for consideration by the other Party), or distribute or otherwise use any Promotional Material relating to a Product. If so instructed by the applicable JPT, a Party will immediately cease to use any Promotional Materials and will collect and destroy any such materials from its sales representatives (and record and document such collection and destruction (and provide a copy of such documentation to the other Party upon request)). The Commercial Lead for a Product will own all right, title and interest in and to any and all Promotional Materials for such Product (except with respect to any Housemarks of the other Party included in any Promotional Materials), and the non-Commercial Lead will execute all documents and take all actions as are reasonably requested by the Commercial Lead to vest title to such Promotional Materials in the Commercial Lead.

Detailing Reports and Audit Rights.

Audits. Each Party will keep complete and accurate records of its Detailing of Products in sufficient detail to permit the other Party to audit its performance of Details hereunder. During regular business hours, with not less than ten (10) business days’ advance written notice and under reasonable obligations of confidentiality, a Party will permit the other Party or its authorized representatives to: (i) have access to the records of Detailing activities maintained by such Party for purposes of verifying the accuracy of reports described in Section 5.8.1 (Reporting); and (ii) audit such records; provided, that such audits may not be performed by a Party more than once per calendar year, such records will be open (in such form as may be available or reasonably requested) to inspection for at least three (3) years following the end of the period to which they pertain, and such records for any particular calendar year will only be subject to one (1) audit. Any and all audits undertaken pursuant to this Section 5.8.2 (Audits) will be performed at the sole and exclusive expense

of the auditing Party and will not be included in Amgen Costs or Partner Costs, as the case may be, for purposes of calculating Collaboration Profit (Loss). If an audit reveals an overstatement of Details of greater than [*] of the correct amount for the audited period, then the audited Party will pay the reasonable out-of-pocket cost of such inspection.

Competing Products. If either Party or its Affiliates has sales representatives Detailing both a Product and a non-Product that is approved by a Governmental Authority for use in the same indication as such Product (a “Competing Product”), then, in addition to the reporting obligations contained in Section 5.8.1 (Reporting), such Party will provide to specified employees of the other Party (as specified by such Party’s JSC members) with a report within thirty (30) calendar days after the end of each calendar month, setting forth [*]. The purpose of such report shall be solely to substantiate the calculation of Sales Force Costs. It shall only be used by the specified employees and it shall not be used by either Party in violation of any Applicable Law. If the JSC or CRC authorizes a sales representative to Detail a Product in the First Position Detail, then [*].

Sales Force [*]. On a country-by-country and Product-by-Product basis, during the period of time beginning [*] of such Product in such country, if either Party intends to [*] in such country that are expected to [*] such Product, then such Party shall provide the other Party with at least sixty (60) days’ prior written notice. In such event, at the request of either Party, the JSC shall meet to [*] in such country (with escalation to the CRC if the JSC is unable to agree on such [*]). The Party that has [*] during the applicable period (but not to exceed [*] that are in excess of its [*].

Collaborative Activities. Activities to be undertaken by the Parties hereunder will be conducted in a collaborative manner as determined by the committee or team overseeing such activities, and in accordance with the terms and conditions of this Agreement, as applicable.

Diligence and Performance Standards. Subject to the decisions made by and oversight of the committees and teams established hereunder, each Party will use, and will assure that each of its Affiliates uses, Commercially Reasonable Efforts in the performance of its and their activities hereunder. Each Party will conduct, and ensure that each of its Affiliates conducts, all of its and their activities with respect to the development, registration, manufacture, distribution, promotion and commercialization of a Product in accordance with this Agreement, the applicable Development Plan, the applicable Brand Plan, applicable Global Payer Plan, applicable Access and Pricing Plan, applicable Country Plans, accepted national and international pharmaceutical industry codes of practices in and for the Collaboration Territory (including the Pharmaceutical Research and Manufacturers of America (PhRMA) Code of Pharmaceutical Marketing Practices and the American Medical Association (AMA) Guidelines on Gifts to Physicians from Industry, as the same may be amended from time to time), and all Applicable Law. The Parties will provide each other with all reasonably requested cooperation to enable each of them to comply with Applicable Law and accepted national and international pharmaceutical industry standards, including permitting each Party to verify the other Party’s compliance therewith.

Violation of Laws. Each Party will promptly notify the other Party of any violation of Applicable Law by its personnel with respect to the conduct of activities under this Agreement. In the event of any such violation, the Parties will promptly confer regarding any such violation and will promptly take remedial or preventative action as may be reasonably required by the applicable JPT with respect thereto. The Parties will have the right to require that any personnel that materially violates Applicable Law or applicable national or international pharmaceutical industry codes of practices cease to perform activities under this Agreement.

Use of Affiliates and Third Party Contractors. Each Party will perform the activities designated to it itself or through any of its Affiliates, and any proposed use of a Third Party to conduct such activities will be subject to the other Party’s prior written consent, such consent not to be unreasonably withheld; provided, that (i) Partner’s consent will not be required for activities Amgen has, prior to the Effective Date, arranged to have performed by Third Parties and which have been disclosed to Partner prior to the Effective Date, and (ii) either Party will be permitted to, upon thirty (30) days’ prior written notice to the other Party, engage a Third Party contract manufacturer, contract research organization, contract sales organization, distributor or wholesaler without the other Party’s consent. Cost overruns resulting from either Party’s use of a Third Party to conduct any such activities will be subject to Section 7.2.6 (Overruns). Each Party will be responsible for compliance by its respective Affiliates and Third Party

contractors with this Agreement and will be responsible for all acts and omissions of such Affiliates and Third Party contractors as if committed or omitted by the applicable Party.

Management of Personnel. Each Party will have sole authority and responsibility for recruiting, hiring, managing, compensating (including paying for all benefits, wages, special incentives, workers’ compensation and employment taxes), disciplining, firing and otherwise controlling the personnel provided by such Party for performance of its obligations hereunder; provided, that each Party will require its personnel to be subject to a confidentiality agreement and Invention assignment commitment prior to, and as a condition of, such personnel performing any such activities hereunder. Each Party will provide the day-to-day management of its sales representatives and other personnel, including furnishing administrative support, financial resources, equipment and supplies.

UP-FRONT PAYMENT AND PROFIT/EXPENSE SHARING

Up-front Payment. As partial consideration for the rights granted to Partner by Amgen pursuant to the terms of this Agreement, Partner will pay to Amgen a non-refundable, non-creditable payment equal to Fifty Million Dollars ($50,000,000.00) within fifteen (15) days after the Effective Date, payable by wire transfer of immediately available funds in accordance with wire transfer instructions of Amgen that will be provided in writing to Partner prior to the Effective Date.

Profit/Expense Sharing. The Parties will share in profits and losses generated by Products in the Collaboration Scope as follows:

Partner Costs. Within forty-five (45) days after the end of each calendar quarter Partner will provide to Amgen a detailed, itemized report of its Development Costs and General Costs, on a Product-by-Product basis, incurred by Partner or its Affiliates in accordance with this Agreement (collectively, “Partner Costs”) in such quarter in the format set forth in the Invoice Schedule attached hereto. In addition to the annual JSC approval of the relevant budgets for each Product, prior to the end of each calendar year, Partner will provide Amgen with a non-binding estimate of its Development Costs and General Costs for each Product for the [*] period (detailed on a calendar year basis) following the [*] covered by such approved budget; provided, that the Parties will review and discuss such estimated costs at the JSC.

Amgen Costs. Within forty-five (45) days after the end of each calendar quarter Amgen will provide to Partner a detailed, itemized report of its Development Costs and General Costs, on a Product-by-Product basis, incurred by Amgen or its Affiliates in accordance with this Agreement (collectively, “Amgen Costs”) in such quarter in the format set forth in the Invoice Schedule attached hereto. In addition to the annual JSC approval of the relevant budgets for each Product, prior to the end of each calendar year, Amgen will provide Partner with a non-

binding estimate of its Development Costs and General Costs for each Product for the [*] period (detailed on a calendar year basis) following the [*] covered by such approved budget; provided, that the Parties will review and discuss such estimated costs at the JSC. For clarity, any costs incurred by or on behalf of Amgen in connection with the research and development of AMG557 for the sole benefit of Japan or the research and development of AMG827 for the sole benefit of the applicable Excluded Territory will not be included in Amgen Costs.

FTE Rate. The FTE Rate used for calculation of Costs pursuant to this Article 7 (Profit/Expense Sharing) with respect to any activity will be the relevant FTE Rate for the calendar year in which such activity was undertaken.

Income Taxes. For the avoidance of doubt, income and withholding taxes imposed on either of the Parties hereunder will not be included in cost sharing hereunder.

Exchange Rate. For purposes of calculating quarterly balancing payments as set forth in Section 7.2.9 (True-Up), Net Revenues, Amgen Costs and Partner Costs will be converted from local currency (if different from U.S. Dollars) to U.S. Dollars in accordance with Section 8.3.2 (Conversions).

Overruns. Each Party will promptly notify the other Party upon becoming aware that the anticipated Costs to be incurred by such Party for a given calendar year will be in excess of the applicable Development Budget, Operations Budget or Commercialization Budget. Unless otherwise agreed by the Parties in advance, in writing, Costs reported by a Party pursuant to Section 7.2.1 (Partner Costs) or 7.2.2 (Amgen Costs) incurred with respect to a Product in excess of [*] percent ([*]%) of the aggregate amounts budgeted to be incurred by or on behalf of such Party for its activities for such Product in such calendar year in the then-current applicable Development Budget, Operations Budget or Commercialization Budget, respectively, will not be included in the calculation of profit (or loss) pursuant to Section 7.2.8 (Calculation of Profit (or Loss)); provided, that such Partner Costs and Amgen Costs in excess of such amount will be included in the calculation of profit (or loss) pursuant to Section 7.2.8 (Calculation of Profit (or Loss)) (A) to the extent such Costs were attributable to: (i) a change in Applicable Law; (ii) a Force Majeure event; [*].

Net Revenues. Within five (5) business days prior to the end of each calendar quarter, each Party will provide the other Party with a reasonably detailed estimate of Net Revenues for such calendar quarter in the countries for which it is the Distribution Party. Within thirty (30) days after the end of each calendar quarter, each Party will provide the other Party with a report of Net Revenues for such calendar quarter in the countries for which it is the Distribution Party, which report will contain a detailed and itemized calculation of Net Revenues for each Product in such countries during such calendar quarter.

Calculation of Profit (or Loss).

Costs.

Allocation. On a calendar quarter-by-calendar quarter basis, Partner will be responsible for one hundred percent (100%) of the following cost items, in the order set forth below, up to the Quarterly Cap for such calendar quarter. Thereafter, Amgen shall be responsible for one hundred percent (100%) of such costs for such calendar quarter.

        Unreimbursed Development Costs and General Costs. First, Partner will be responsible for one hundred percent (100%) of Unreimbursed Development Costs and General Costs up to the Quarterly Cap.

        Reimbursed Development Costs. If, following reimbursement for Unreimbursed Development Costs and General Costs, the Quarterly Cap has not yet been met, then Partner will be responsible for one hundred percent (100%) of Reimbursed Development Costs up to the Quarterly Cap.

    Quarterly Cap. The “Quarterly Cap” for a given calendar quarter shall, during the applicable calendar year set forth below, be as follows:

Calendar Year

Quarterly Cap

2012

65% of Total Costs for the applicable calendar

quarter - [*]

2013

65% of Total Costs for the applicable calendar

quarter + [*]

2014

65% of Total Costs for the applicable calendar

quarter

2015 and each year thereafter

50% of Total Costs for the applicable calendar

quarter

        Profit. The total profit for a calendar quarter will be calculated by Amgen by first deducting from aggregate Net Revenues for each Product for such quarter a percentage of such Net Revenues equal to the applicable “Inventorship Margin” set forth below, which will be paid to Amgen to reflect Amgen’s inventorship of the Products:

Inventorship Margin

AMG827

Other Products

[*]

True-up. Within sixty (60) days after the end of each calendar quarter, Amgen will calculate and provide to Partner a report of the amount each Party is responsible for under Section 7.2.8.1 (Costs) for such quarter, and a report of the amount each Party is entitled to under Section 7.2.8.2 (Profit). The resulting amounts under Sections 7.2.8.1 (Costs) and 7.2.8.2 (Profit) will be the “Collaboration Profit (Loss)” for such calendar quarter. A balancing payment will be made between the Parties in order to effect the profit and loss sharing allocation set forth in Section 7.2.8 (Calculation of Profit (or Loss)). The net paying Party will make a payment pursuant to this Section 7.2.9 (True-up) within thirty (30) days after delivery of such report of Collaboration Profit (Loss).

Payments. Payments pursuant to this Article 7 (Profit/Expense Sharing) will be made in accordance with the provisions of Article 8 (Payments).

Calculation of Sales Force Costs. Sales force FTE costs for each of the Parties will be determined by including in Partner Costs or Amgen Costs, as the case may be, a pro rata portion of each Party’s sales representative’s FTE Rate as

follows: (i) [*] if such sales representative Details only a single Product (and no other products) with the approval of the CRC; (ii) [*] if such sales representative Details two (2) products with a Product as the First Position Detail or Details only a Product without the approval of the CRC; (iii) [*] if such sales representative Details three (3) or more products with a Product as the First Position Detail; (iv) [*] if such sales representative Details two (2) products with a Product as the Second Position Detail; (v) [*] if such sales representative Details three (3) or more products with a Product as the Second Position Detail; and (vi) [*] if such sales representative Details three (3) or more products with a Product as the Other Detail. If a sales representative Details more than one (1) Product, then the foregoing percentages will be aggregated for each such Product. For the avoidance of doubt, if a sales representative Details a Product in more than one (1) position, then a pro rata share of the foregoing percentages, to be calculated based on the time spent by such sales representative on Detailing such Product in each such position, will be included in Partner Costs or Amgen Costs, as the case may be. For periods in which sales representatives are performing activities in support of the collaboration but are not Detailing Products (e.g., during launch preparation or training), FTE costs will be calculated based upon percent of effort, resource utilization or other reasonable measure, in each case calculated and allocated in accordance with the applicable Party’s accounting procedures, consistently applied.

Kirin-Amgen and Takeda Payments. For clarity, the Parties agree and acknowledge that any payments received by Amgen from (i) in the case of ▇▇▇▇▇▇, ▇▇▇▇▇-▇▇▇▇▇, Inc. or Kyowa Hakko Kirin Co., Ltd and (ii) in the case of AMG557, Takeda Pharmaceutical Company Limited, in each case pursuant to the related Excluded Territory Agreement with such Third Party, shall be excluded from the calculation of Collaboration Profit (Loss). Any such payments shall not, in any way (in part or in full), reduce Amgen Costs hereunder, and Amgen shall be entitled to retain any such payments in full without compensation to, or any separate accounting or audit right undertaken by, Partner.

Example. The Profit (Loss) Example Schedule sets forth an example of calculation and true-up of the Collaboration Profit (Loss).

Calculation of Net Revenues. In calculating Net Revenues for the purposes of this Article 7 (Profit/Expense Sharing):

Free Products. Any disposal of a Product at no charge for, or use of a Product without charge in, clinical or pre-clinical trials, given as free samples, or distributed at no charge to patients unable to purchase the same will not be included in Net Revenues.

Bundled Products. Where a Product is sold in a Bundle, then for the purposes of calculating Net Revenues under this Agreement, such Product will be deemed to be sold for an amount equal to [X ÷ (X + Y)] × Z, where: X is the average sales price during the applicable reporting period generally achieved for such dosage form of such Product in the Collaboration Scope; Y is the sum of

the average sales price during the applicable reporting period generally achieved in the Collaboration Territory, when sold alone, by each pharmaceutical product in the relevant dosage form included in the Bundle (excluding such Product); and Z equals the price at which the Bundle was actually sold. In the event that such Product or one or more of the other pharmaceutical products in the Bundle are not sold separately in the relevant dosage form, Net Revenues from the sale of such Bundle will be reasonably allocated between such Product and the other product(s) in such Bundle based upon their relative values and the Parties will determine the equitable fair market prices to apply to such Bundle; provided, that in the event of a disagreement with respect to such relative values, the Parties will engage a mutually agreed upon independent expert to make the final determination with respect thereto. Notwithstanding the foregoing, no Product will be sold in a Bundle if such sale would violate Applicable Law.

Excluded Losses. The following losses will not be charged to the Collaboration Profit (Loss): (i) losses of a Party to the extent attributable to a breach of this Agreement by such Party, or (ii) losses subject to indemnification pursuant to Section 13.1 (Indemnity by Partner) or Section 13.2 (Indemnity by Amgen).

Manufacturing Costs Calculation and True-Up. Manufacturing Standard Costs for a Product, calculated as part of Development Costs, will be included in Amgen Costs and Partner Costs, as applicable, at the time of manufacture of such Product. Prior to Technical Feasibility, Manufacturing Actual Costs for a Product intended for use in a clinical trial, calculated as part of Development Costs, will be included in Amgen Costs and Partner Costs, as applicable, at the time of manufacture of such Product. After Technical Feasibility, Manufacturing Actual Costs for a Product intended for use in a clinical trial, calculated as part of Development Costs, will be included in Amgen Costs and Partner Costs, as applicable, at the time such Product is shipped to a site for use of such Product in a clinical trial. Subject to Section 4.4 (Distribution), Manufacturing Actual Costs for a Product for commercial use, calculated as part of General Costs, will be included in Amgen Costs and Partner Costs, as applicable, at the time of sale of such Product. In addition, due to the fact that Manufacturing Actual Costs may not be known at the time such costs are to be included within the Collaboration Profit (Loss), for the purposes of determining Development Costs or General Costs for a particular calendar quarter, the Manufacturing Lead will, to the extent any manufacturing costs are to be calculated using Manufacturing Actual Costs, use the then-current estimated Manufacturing Actual Costs for such calendar quarter. By March 31 of each calendar year, the Manufacturing Lead will reconcile the estimated Manufacturing Actual Costs included in Development Costs and General Costs in the prior calendar year with the final Manufacturing Actual Costs for such Product and provide such reconciliation to the other Party. If such reconciliation leads to an over or under payment by either Party, a balancing payment will be made between the Parties in order to maintain the intended profit and loss sharing allocation set forth in this Agreement within thirty (30) days after delivery of such reconciliation report by the Manufacturing Lead and agreement thereon by the Parties.

Budget Deadlocks. In the event that the JSC is unable to approve [*] Development Budget, Operations Budget or Commercialization Budget prior to the expiration of any such budget, then, until approval of such budget by the CRC, each Party will be entitled to continue the Designated Amgen Activities and Designated Partner Activities, as applicable, and include its Development Costs and General Costs, as applicable, in the calculation of Collaboration Profit (Loss) for any calendar quarter not covered by an approved budget, until such time as the aggregate Development Costs and General Costs of such Party included in the calculation of Collaboration Profit (Loss) for [*] equal the amount of such Party’s Development Costs and General Costs included in the then most recent estimate provided under Sections 7.2.1 (Partner Costs) and 7.2.2 (Amgen Costs), as applicable, plus [*] of such estimate.

Program Recommitment. [*], after the applicable Continued Development Meeting for a Product has been held and upon consultation at the CRC, in the event either (or both) Party(ies) do not wish to continue to participate in the continued development and commercialization of such Product, each Party will have the right to suspend its participation by providing the other Party with a written notice thereof on or prior to [*] days following the applicable Continued Development Meeting. A Party so suspending its commitment will be referred to as a

“Suspending Party” and a Party not doing so a “Non-Suspending Party”.

Suspension.

Suspension Election. If only one Party delivers a notice of suspension with respect to a Product (a “Suspension Election”), then the remaining provisions of this Section 7.8 (Program Recommitment) shall apply. If both Parties deliver a notice of suspension with respect to a Product, then the Agreement shall be deemed to be terminated with respect to such Product in accordance with Section 14.2 (Termination for Convenience) and Section 14.6.1 (Product by Product Termination) and Amgen shall be the Continuing Party with respect to such Product.

Transition. Upon making a Suspension Election, the Suspending Party will, at the Non-Suspending Party’s cost, undertake all reasonable efforts to effect a smooth and orderly transition of its development, regulatory and commercial activities and responsibilities under this Agreement with respect to such Product to the Non-Suspending Party. If the Suspending Party is the Manufacturing Lead for such Product, then, at the Non-Suspending Party’s cost, the Suspending Party will use all reasonable efforts to continue to supply Product for clinical use and complete any commercial process development activities initiated prior to the effective date of such Suspension Election; provided, that, the Manufacturing Lead will have the right to transition such manufacturing to a contract manufacturer or, if agreed to by the Non-Suspending Party, to the Non-Suspending Party. For clarity, from and after the effective date of any Suspension Notice, the Suspending Party shall not be liable for any Development Costs or General Costs for such Product committed before the effective date of the Suspension Notice but not yet incurred at that date or otherwise incurred after such date.

Committee Participation. Upon making a Suspension Election and until such time as the Suspending Party elects to resume funding its share of Development Costs and General Costs with respect to such Product pursuant to Section 7.8.2 (Re-Entry Right) below, the Suspending Party’s right to participate on the CRC, the JSC, any JPT and any subcommittee or subteam thereunder will be limited to a right to participate in any meetings brought before such committee or team without any right to vote on any matter that specifically relates to such Product (for clarity the Suspending Party will retain the right to vote on any matter that relates to any other Product). Additionally, if the Suspending Party was the Development Lead and Commercial Lead for such Product, then the Non-Suspending Party shall be the Development Lead and Commercial Lead going forth, and the Suspending Party shall not be entitled to resume such role even if such Party elects to resume funding its share of Development Costs and General Costs with respect to such Product pursuant to Section 7.8.2 (Re-Entry Right) below. Additionally, the Non-Suspending Party shall promptly share with, and provide access to, the Suspending Party (i) all clinical trial data and results within the

Program Intellectual Property, (ii) such other Know-How within the Product Intellectual Property generated before the date of the Suspension Election; and (iii) any other information reasonably requested by the Suspending Party related to such Product.

Subsequent Termination. If the Non-Suspending Party subsequently decides that it is no longer willing to continue further development and commercialization of the Product, then the Non-Suspending Party may elect to terminate further development and commercialization by providing the Suspending Party with [*] prior written notice (a “Termination Election”). If the Suspending Party is Partner and Amgen delivers a Termination Election during the Re-Entry Period, then upon receipt of such Termination Election from Amgen, Partner shall have the right upon prior written notice, delivered by no later than [*] following receipt of Amgen’s Termination Election, to elect to continue with the further development and commercialization of the Product, in which case, Partner shall thereafter be deemed to be the Non-Suspending Party and Amgen shall be deemed to be the Suspending Party. If Partner does not elect within such [*] period to continue with such development or commercialization or if Partner is the Non-Suspending Party, then upon the effective date of a Termination Election, the Agreement shall be deemed to be terminated with respect to such Product in accordance with Section 14.2 (Termination for Convenience) and Section 14.6.1 (Product by Product Termination) and Amgen shall be the Continuing Party with respect to such Product.

Re-Entry Rights.

Re-Entry Period. With respect to any non-terminated Product subject to a Suspension Election, at any time beginning upon receipt of the Suspension Election until [*] following the receipt of the flash memo for the applicable Stage 2 Clinical Trial for such Product and receipt of any information requested by the Suspending Party that is reasonably necessary to determine whether to re-enter the program (the “Re-Entry Period”), the Suspending Party will have the right to re-enter the program by written notice (a “Re-Entry Notice”) to the Non-Suspending Party, effective as of the date of receipt of such notice by the Non-Suspending Party.

Re-Entry Payment. In the event of such re-entry, the Suspending Party will pay the Non-Suspending Party an amount equal to [*].

Lapse. If the Suspending Party fails to provide the Re-Entry Notice with respect to a Product during the applicable Re-Entry Period, then the Suspending Party shall be deemed to have terminated the Agreement with respect to such Product in accordance with Section 14.2 (Termination for Convenience) and Section 14.6.1 (Product by Product Termination).

Out-license. If, during the Re-Entry Period for a Product, the Non-

Suspending Party elects to grant to a bona fide Third Party the exclusive right to develop or commercialize such Product in any country within the Collaboration Territory, then the Non-Suspending Party will provide the Suspending Party with [*] prior written notice (the “Out-License Election”). If the Suspending Party fails to provide a Re-Entry Notice within [*] of receipt of the Out-License Election and the Out-License Election relates to only certain countries within the Collaboration Territory, then the Suspending Party’s right to re-enter the program shall exclude such countries. If the Suspending Party fails to provide a Re-Entry Notice within [*] of receipt of the Out-License Election and the Out-License Election relates to all countries within the Collaboration Territory, then, then the Suspending Party’s right to provide a Re-Entry Notice with respect to such Product shall terminate.

Appropriate Measure of Value. Each of the Parties acknowledges that the value provided by the other hereunder is comprised of many related items, including performance of various services, access to development, regulatory, manufacturing and commercial expertise, clinical data and other financial and non-financial consideration and that the amount of the Inventorship Margin, and the ratio of profit and expense sharing set forth herein are intended to capture such value as an aggregate. Therefore, the increase, decrease or lapse of any particular items or rights (including Patents), including allocation of operational responsibilities between the Parties, will not affect the amount of such payment, or the ratio of profit and expense sharing and the Parties agree that both the amount and duration of such payment and the ratio of profit and expense sharing are reasonable.

No Other Compensation. Other than as explicitly set forth in this Agreement, neither Party will be obligated to pay any additional fees, milestone payments, royalties or other payments of any kind to the other hereunder.

Currency.

Payments. All payments made hereunder between the Parties will be made in U.S. Dollars except as set forth in Section 8.5 (Blocked Currency) or as otherwise agreed by the Parties. Each Party will pay all sums due hereunder by wire transfer, or electronic funds transfer (EFT) in immediately available funds. If the EFT option is chosen by Amgen or Partner, a completed electronic funds transfer form will be provided in a timeframe that facilitates timely payment. Each Party will promptly notify the other Party of the appropriate account information to facilitate any such payments. All amounts set forth in any budget established under this Agreement will be expressed in U.S. Dollars except as otherwise agreed by the Parties.

Conversions. With respect to amounts required to be converted into another currency for calculation or payment, hereunder, such amounts will be converted using a rate of exchange which corresponds to the rate used for conversion

between the relative currencies by whichever Party recorded the relevant receipt or expenditure, for the respective reporting period in its books and records that are maintained in accordance with GAAP or IFRS, as the case may be. If a Party is not required to perform such a currency conversion for its GAAP or IFRS reporting with respect to the applicable period, then for such period such Party will make such conversion using the rate of exchange which corresponds to the noon buying rate as published in the Wall Street Journal, Eastern U.S. Edition on the second to last business day of the calendar quarter (or such other publication as agreed-upon by the Parties) in which such receipt or expenditure was incurred.

Audits. Each Party will keep complete and accurate records pertaining to the activities to be conducted hereunder in sufficient detail to permit the other Party (the “Auditing Party”) to confirm the accuracy of all payments due hereunder, and such records will be open (in such form as may be available or reasonably requested) to inspection for [*] following the end of the period to which they pertain. The Auditing Party will have the right, at its own expense to have an independent, certified public accountant, selected by it, perform a review of the records of the other Party (the “Audited Party”) applicable to amounts payable hereunder (including any records kept in the ordinary course of the Audited Party’s business) during regular business hours, with not less than ten (10) business days’ advance written notice and under reasonable obligations of confidentiality. The report of such accountant will be made available to both Parties simultaneously, promptly upon its completion. The Auditing Party’s right to perform an audit pertaining to any calendar year will expire [*] after the end of such year and the books and records for any particular calendar year will only be subject to one (1) audit. Should an inspection pursuant to this Section 8.4 (Audits) lead to the discovery of a payment discrepancy, then the appropriate Party will pay to the other the amount of the discrepancy (plus, if the error was in favor of the Auditing Party, interest accrued at the Contract Interest Rate, compounded annually from the day the relevant payment(s) were due). If a payment discrepancy was greater than [*] of the correct amount for the audited period and the discrepancy was in favor of the Audited Party, then the Audited Party will pay the reasonable out-of-pocket cost of such inspection, but in no case will the costs of an audit pursuant to this Section 8.4 (Audits) be included in Partner Costs or Amgen Costs or otherwise included in the calculation of Collaboration Profit (Loss). This Section 8.4 (Audits) does not apply to or include manufacturing audits or regulatory inspections.

Blocked Currency. If Applicable Law in the Collaboration Territory prevents the prompt remittance of any payments with respect to sales therein, the paying Party will have the right and option to make such payments by depositing the amount thereof in local currency to the other Party’s account in a bank or depository in such country.

Taxes.

Withholding. If Applicable Law requires a Party to pay or withhold Taxes with respect to any payment to be made pursuant to this Agreement, the paying Party will notify the other in writing of such payment or withholding requirements prior to making the payment and provide such assistance to the receiving Party,

including the provision of such documentation as may be required by a tax authority, as may be reasonably necessary in such Party’s efforts to claim an exemption from or reduction of such Taxes. Each Party will withhold any Taxes required by law to be withheld from the amount due, remit such Taxes to the appropriate tax authority, and furnish the other Party with proof of payment of such Taxes promptly following payment thereof. If Taxes are paid to a tax authority, each Party will provide the other such assistance as is reasonably required to obtain a refund of Taxes withheld, or obtain a credit with respect to Taxes paid. In the event that the governing tax authority retroactively determines that a payment made by a Party to the other pursuant to this Agreement should have been subject to withholding (or to additional withholding) for Taxes, and such Party (the “Withholding Party”) remits such withholding Taxes to the tax authority, the Withholding Party will have the right to offset such amount, including any interest and penalties that may be imposed thereon (except to the extent any such interest or penalties result from the negligence of the Withholding Party), against future payment obligations of the Withholding Party under this Agreement (or, at the option of the Withholding Party, the Withholding Party will have the right to invoice the other Party for such amount, and the other Party will pay such amount within sixty (60) days of the receipt of such invoice); provided, that the Withholding Party may also pursue reimbursement by any other available remedy.

Indirect Taxes. All payments are exclusive of Indirect Taxes. If any Indirect Taxes are chargeable in respect of any payments, the paying Party shall pay such Indirect Taxes at the applicable rate in respect of such payments following receipt, where applicable, of an Indirect Taxes invoice in the appropriate form issued by the receiving Party in respect of those payments. The Parties shall issue invoices for all amounts payable under this Agreement consistent with Indirect Tax requirements and irrespective of whether the sums may be netted for settlement purposes. If such amounts of Indirect Taxes are refunded by the applicable Governmental Authority or other fiscal authority subsequent to payment, the Party receiving such refund will transfer such amount to the paying Party within forty-five (45) days of receipt.

Employee Taxes. Each Party shall be responsible for taxes based on, imposed on or calculated by reference to any employees employed by that Party.

Imports. For the avoidance of doubt, the Parties acknowledge and agree that none of the upfront payment or royalties payable under this Agreement are related to the license (or right) to import or any import of Products. The Parties shall cooperate in accordance with Applicable Laws to ensure where permissible no import duties are paid on imported Product. The Parties shall cooperate to ensure that the Party responsible for shipping values clinical Product in accordance with Applicable Laws and minimises where permissible any such duties and any related import taxes that are not reclaimable from the relevant authorities. The receiving Party shall be responsible for any import clearance, including payment of any import duties and similar charges, in connection with any Products transferred to such Party under this Agreement.

Payment Flows. The Parties recognize that this Agreement is global in nature and does not set out in detail how the financial flows will be implemented at a legal entity level in order to achieve the economic sharing of profits and losses generated by the Products as set forth in this Agreement. At least eighteen (18) months prior to first commercial launch of a Product, the Parties will discuss and agree upon the principles for such profit and loss sharing at a legal entity level. The Parties will use reasonable efforts to minimize the impact on both Parties of irrecoverable and/or non-creditable Indirect Taxes, including, where appropriate, causing their local Affiliates to enter into a “Marketing Services Agreement” with one another or otherwise discussing how to address the issue. For clarity, the provisions of this Section 8.6.5 (Payment Flows) will in no way change the allocation between the Parties of Development Costs and General Costs set forth in Section 7.2.8.1 (Costs) or of Net Revenues set forth in Section 7.2.8.2 (Profits).

Late Payment. Any payments or portions thereof due hereunder which are not paid when due will bear interest at the Contract Interest Rate, compounded annually, calculated on the number of days such payment is delinquent. This Section 8.7 (Late Payment) will in no way limit any other remedies available to either Party.

Change in Accounting Periods. From time to time, either of the Parties may change its accounting and financial reporting practices from calendar quarters and calendar years to fiscal quarters and fiscal years or vice versa. If a Party notifies the other in writing of a change in its accounting and financial reporting practices from calendar quarters and calendar years to fiscal quarters and fiscal years or vice versa, then thereafter, beginning with the period specified in the notice, the Parties will cooperate to determine a way to report and reconcile each Party’s accounting periods so as to facilitate payments to be made hereunder.

Distracting Program. Except as set forth in Sections 9.2 (Post-Effective Date Affiliates), 9.3 (Termination, Divestiture or Inclusion) and 9.4 (Pre-Clinical Research and Development Programs):

Partner will not, during the Term and, other than in the event of termination by Partner pursuant to Section 14.3 (Termination for Breach), for [*] thereafter, itself or through its Affiliates, conduct or participate in, or advise, assist or intentionally enable any Third Party to conduct or participate in, any Distracting Program anywhere in the world; provided, that [*];

Amgen will not, during the Term, itself or through its Affiliates, conduct or participate in, or advise, assist or intentionally enable any Third Party to conduct or participate in, any Distracting Program in the Collaboration Territory; and

[*].

Post-Effective Date Affiliates. If a Party enters into a Distracting Transaction then it will provide notice to the other Party, within [*] business days after the closing of the Distracting Transaction, describing in reasonable detail, to the extent permitted by Applicable Law and without disclosing any proprietary information, the Distracting Program. During the pendency of any potential Distracting Transaction, and until the provisions of Section 9.3 (Termination, Divestiture or Inclusion) are fully implemented, the Party entering into the Distracting Transaction will Segregate the Distracting Program from programs for the Products.

Termination, Divestiture or Inclusion. The notice provided pursuant to Section 9.2 (Post-Effective Date Affiliates) will include a notification as to whether the Party entering into the Distracting Transaction intends to Divest, terminate or include in the collaboration the Distracting Program in accordance with this Section 9.3 (Termination, Divestiture or Inclusion):

Divestiture. If a Party elects to Divest the Distracting Program, then it will Segregate such Distracting Program from the programs for the Products and Divest such Distracting Program within [*] months of the closing of the Distracting Transaction. The divesting Party and its Affiliates (including the Affiliate with the Distracting Program) will not directly or indirectly assert any intellectual property or proprietary right embodied in the Distracting Program and under the control of the divesting Party or its Affiliates as a result of the Distracting Transaction, against or with respect to Products or otherwise obstruct the Parties’ (or their Affiliates, sublicensees’, contractors’ or agents’) efforts under this Agreement or, if Partner is the divesting Party, Amgen’s (or its Affiliates, sublicensees’, contractors’ or agents’) efforts with respect to Products in the Excluded Territory. If the divesting Party fails to complete a divestiture of the Distracting Program within [*] months of the closing of the Distracting Transaction, then such Party will be deemed to have chosen to terminate the Distracting Program, effective as of such [*] month anniversary, and will promptly comply with the requirements of Section 9.3.2 (Termination); provided, that if at the expiration of such [*] month period, the divesting Party has agreed terms with a Third Party to Divest the Distracting Program then such [*] month period will be extended as required for the divesting Party and such Third Party to consummate the transaction, but in no event will such extension exceed an additional [*] days.

Termination. If a Party elects to terminate such Distracting Program, it will terminate all activities of such Distracting Program within [*] days after the closing of the Distracting Transaction, during which period it will Segregate such Distracting Program from the programs for the Products. The terminating Party and its Affiliates will not directly or indirectly assert any intellectual property or proprietary right of the Distracting Program against or with respect to Products or otherwise to obstruct the Parties’ (or their Affiliates, sublicensees’, contractors’ or agents’) efforts under this Agreement or if Partner

is the terminating Party, Amgen’s (or its Affiliates, sublicensees’, contractors’ or agents’) efforts with respect to Products in the Excluded Territory during such termination period or thereafter.

Inclusion. If a Party elects to include the Distracting Program in the collaboration, then such Party (the “Distracting Transaction Party”) will provide written notice within [*] days after the closing of the Distracting Transaction of such election to the other Party, together with a non-confidential summary of the related Distracting Program. If the non-Distracting Transaction Party desires to evaluate such Distracting Program, then the non-Distracting Transaction Party will notify the Distracting Transaction Party within [*] days of its receipt of such notice. Promptly after the Distracting Transaction Party’s receipt of such evaluation notice, the Distracting Transaction Party will provide the non-Distracting Transaction Party with a confidential summary of the Distracting Program, including material pre-clinical and clinical data and proposed development plan and budget (as well as such other information that the non-Distracting Transaction may reasonably request), which summary will be deemed to be Confidential Information of the Distracting Transaction Party under this Agreement (and the non-Distracting Transaction Party shall be entitled to use such information solely for the purpose of evaluating whether to include such Distracting Program in the collaboration). Within [*] days of its receipt of such summary, the non-Distracting Transaction Party will notify the Distracting Transaction Party of its election to either (i) include the Distracting Program in the collaboration or (ii) decline to include such Distracting Program in the collaboration. If the non-Distracting Transaction Party agrees in writing to include such Distracting Program in the collaboration, then (a) the Distracting Program will be included under the terms of this Agreement and all the technology, intellectual property and tangible materials (including biological compounds, chemical compounds, intermediates, assays, screens, animal models and reagents) of such Distracting Program will be considered within the Product Intellectual Property; (b) the Distracting Products included in the Distracting Program will be deemed Products hereunder; (c) a JPT will be formed for each such Distracting Product and each such JPT will develop a Development Plan and Development Budget for each Distracting Product, for review and approval by the JSC; (d) all Development Costs, General Costs and profits with respect to each such Distracting Product [*]; and (e) the Parties will enter into an amendment or supplement to this Agreement to the extent necessary to specify which Party will be the Development Lead, Manufacturing Lead, and Commercial Lead, plus such other changes, modifications and assignments as are reasonably necessary to effectuate the addition of such Distracting Product. If the non-Distracting Transaction Party does not agree to include such Distracting Program in the collaboration, then (i) from and after the date of such election, the obligations of the Distracting Transaction Party set forth in Section 9.1 (Distracting Program) will no longer apply with respect to such Distracting Program, and (ii) the non-Distracting Party shall destroy the confidential summary of the Distracting Program provided to it by the Distracting Transaction Party (provided, that the non-Distracting Party shall be

entitled to retain one (1) copy of such information for its record-keeping purposes).

Pre-Clinical Research and Development Programs. Notwithstanding anything in this Article 9 (Distracting Products), either Party will have the right, either itself or through its Affiliates, to conduct non-clinical research and non-clinical development on any Distracting Product, subject to this Section 9.4 (Pre-Clinical Research and Development). At least [*] days prior to the anticipated initiation of the first [*] for such Distracting Product, the Party conducting such activities (the “Researching Party”) will notify the non-Researching Party and provide a non-confidential summary of the related Distracting Program to the non-Researching Party (“Program Notice”). If the non-Researching Party desires to evaluate such Distracting Program, then the non-Researching Party will notify the Researching Party within thirty (30) days of its receipt of the Program Notice. Promptly after the Researching Party’s receipt of such evaluation notice, the Researching Party will provide the non-Researching Party with a confidential summary of the Distracting Program, including material pre-clinical data and proposed development plan and budget (as well as such other information that the non-Researching Party may reasonably request), which summary will be deemed to be Confidential Information of the Researching Party under this Agreement (and the non-Researching Party shall be entitled to use such information solely for the purpose of evaluating whether to include such Distracting Program in the collaboration). Within [*] days of its receipt of such summary, the non-Researching Party will notify the Researching Party of its election to either (i) include the Distracting Program in the collaboration, in which case the terms of Section 9.3.3 (Inclusion) will apply with respect to such Distracting Program (provided, that the Researching Party will be entitled to receive a [*]) or (ii) decline to include such Distracting Program in the collaboration. If the non-Researching Party declines to include such Distracting Program in the collaboration, then (i) from and after the date of such election, the obligations of the Researching Party set forth in Section 9.1 (Distracting Program) will no longer apply with respect to such Distracting Program, and (ii) the non-Researching Party shall destroy the confidential summary of the Distracting Program provided to it by the Researching Party (provided, that the non-Research Party shall be entitled to retain one (1) copy of such information for its record-keeping purposes).

Reasonable Restrictions. Each of the Parties acknowledges the provisions of this Article 9 (Distracting Products) are reasonable and necessary to protect the legitimate interests of the other Party and to encourage the free sharing of information between the Parties with respect to Products, and each of the Parties agrees not to contest such limitations in any proceeding. Each Party acknowledges that the other Party would not have entered into this Agreement absent the restrictions set forth in this Article 9 (Distracting Products) and that a breach or threatened breach of this Article 9 (Distracting Products) would be likely to result in irreparable harm to such Party for which there is no adequate remedy at law. Therefore, the Parties will be entitled to obtain from any court of competent jurisdiction injunctive relief, specific performance, and an equitable accounting of any earnings, profits or benefits arising out of any such breach without the requirement to post a bond or to demonstrate irreparable harm, balancing of ▇▇▇▇▇, consideration of the public

interest or inadequacy of monetary damages as a remedy. Nothing in this Section 9.5 (Reasonable Restrictions) is intended or will be construed to limit in any way either Party’s right to equitable relief or any other remedy for breach of this or any other provision of this Agreement.

Invention Ownership. Each Party will own all right, title, and interest in and to all Inventions that are made by or on behalf of such Party, solely or independent of the other Party, and all intellectual property rights related thereto, and any Invention that is jointly made will be owned jointly by the Parties. Inventorship will be determined according to United States Patent Law (without reference to any conflict of law principles).

Copyright Ownership; Certain Confidential Information. Each Party will own all right, title, and interest in and to all Copyrights created pursuant to this Agreement that are authored by or on behalf of such Party, solely or independent of the other Party, and all intellectual property rights related thereto. The Parties will jointly own all right, title, and interest in and to all Copyrights created pursuant to this Agreement that are authored by or on the behalf of the Parties jointly, and all intellectual property rights related thereto. Notwithstanding the foregoing, any Copyrights pertaining to Promotional Materials or training materials for a Product will be owned solely by the Commercial Lead for such Product.

Joint Ownership. Except as expressly provided in this Agreement, it is understood that neither Party will have any obligation to obtain any approval or consent of, nor pay a share of the proceeds to or account to, the other Party to practice, enforce, license, assign or otherwise exploit Inventions or intellectual property (including Copyrights and Product Trademarks) owned jointly by the Parties hereunder, and each Party hereby waives any right it may have under the laws of any jurisdiction to require such approval, consent or accounting. Each Party agrees to cooperate with the other Party, as reasonably requested, and to take such actions as may be required to give effect to this Section 10.3 (Joint Ownership) in a particular country within the Collaboration Territory.

License Grant by Amgen. Amgen hereby grants and causes its Affiliates to grant to Partner during the Term a [*], fully-paid, royalty-free license to Amgen Intellectual Property and Program Intellectual Property solely (i) to the extent necessary to conduct the Designated Partner Activities and (ii) to exercise and perform Partner’s other rights and obligations under the terms of this Agreement. Such license is sublicensable by Partner or its Affiliates solely in accordance with Section 6.4 (Use of Affiliates and Third Party Contractors).

License Grant by Partner. Partner hereby grants and causes its Affiliates to grant to Amgen and its Affiliates a [*], fully-paid, royalty-free license to Partner Intellectual Property and Program Intellectual Property solely (i) to the extent necessary to conduct the Designated Amgen Activities and (ii) to exercise and perform Amgen’s other rights and obligations under the terms of this Agreement. The foregoing license is sublicensable by Amgen or its Affiliates in accordance with Section 6.4 (Use of Affiliates and Third Party Contractors). Additionally, Partner hereby grants and causes its Affiliates to grant to Amgen and its Affiliates a [*], irrevocable, fully-paid, royalty-free, world-wide license to Partner Intellectual Property and Program Intellectual Property solely to use, make, have made, sell, offer for sale and import Products for all uses in the Excluded Territory (which license is sublicensable by Amgen or its Affiliates to Third Parties to whom Amgen or its Affiliates also grant a license in the Excluded Territory to Know-How or Patents owned or controlled by Amgen with respect to Product(s) , or the manufacture, formulation or use thereof; [*]).

Prosecution and Maintenance.

Amgen Intellectual Property. Subject to the provisions of Section 2.10 (Patent Coordinators), Amgen will control, itself or through outside counsel, and have final decision making authority (after consultation with Partner in accordance with the terms and conditions of this Agreement) with respect to the Prosecution and Maintenance of the Patents within the Amgen Intellectual Property in the Collaboration Territory that claim a Product, and with respect to preparation and filing for any Patent Extensions.

Partner Intellectual Property. Subject to the provisions of Section 2.10 (Patent Coordinators), Partner will control, itself or through outside counsel, and have final decision making authority (after consultation with Amgen in accordance with the terms and conditions of this Agreement) with respect to the Prosecution and Maintenance of the Patents within the Partner Intellectual Property in the Collaboration Territory that claim a Product, and with respect to preparation and filing for any Patent Extensions.

Program Intellectual Property. Subject to the provisions of Section 2.10 (Patent Coordinators), Amgen will have the first right (but not the obligation) to control, through outside counsel, and have final decision making authority (after consultation with Partner in accordance with the terms and conditions of this Agreement) with respect to the Prosecution and Maintenance of the Patents and Product Trademarks within the Program Intellectual Property (the “Program Patents and Trademarks”), and with respect to preparation and filing for any

Patent Extensions. If Amgen desires to abandon the prosecution of a Program Patent or Trademark, then it will inform Partner thereof in writing with sufficient advance notice to reasonably enable Partner to assume the filing or prosecution of such Program Patent or Trademark (but in no event later than [*] days prior to the next deadline for any action that may be taken with respect such Program Patent or Trademark with the U.S. Patent and Trademark Office or any non-U.S. patent office) at Partner’s non-reimbursable cost.

Review and Comment Rights - Patents. Through the Patent Coordinators: (i) the filing Party will provide the non-filing Party with copies of and an opportunity to review and comment upon the text of the applications relating to the applicable Patents at least [*] days before filing; provided, that if it is not reasonably practicable to provide such application in such [*] day period, then the filing Party will provide either a draft copy of such application or a statement of intent to file such application in such [*] day period; (ii) the filing Party will provide the non-filing Party with a copy of each submission made to and document received from a patent authority, court or other tribunal regarding any Patent reasonably promptly after making such filing or receiving such document, including a copy of each application for each Patent as filed together with notice of its filing date and application number; (iii) the filing Party will keep the non-filing Party advised of the status of all material communications, and actual and prospective filings or submissions regarding the Patents, and will give the non-filing Party copies of and an opportunity to review and comment on any such material communications, filings and submissions proposed to be sent to any patent authority or judicial body; and (iv) the filing Party will consider in good faith the non-filing Party’s comments on such communications, filings and submissions for the Patents. With respect to any filings or other materials provided to the non-filing Party under this Section 10.6 (Prosecution and Maintenance), the filing Party will have the right to redact any manufacturing information and any information relating to any product other than Products from any such filings and materials. Either Patent Coordinator may escalate to the JSC whether to obtain any license to Third Party Patents or Know-How; provided, that in the event of a disagreement at the JSC with respect to such decision, Amgen will make the final decision with respect thereto.

Review and Comment Rights - Product Trademarks. Through the Patent Coordinators: (i) the filing Party will provide the non-filing Party with copies of and an opportunity to review and comment upon the text of each application relating to registration of a Product Trademark at least [*] business days before filing; (ii) the filing Party will provide the non-filing Party with a copy of each submission made to and document received from a trademark registration authority, court or other tribunal regarding any Product Trademark reasonably promptly after making such filing or receiving such document, including a copy of each application for registration of each Product Trademark as filed together with notice of its filing date and application number; (iii) the filing Party will keep the non-filing Party advised of the status of all material communications, and actual and prospective filings or submissions regarding the application for

registration of Product Trademarks, and will give the non-filing Party copies of and an opportunity to review and comment on any such material communications, filings and submissions proposed to be sent to any trademark registration authority or judicial body; and (iv) the filing Party will consider in good faith the non-filing Party’s comments on such communications, filings and submissions for the Product Trademarks.

Defense and Settlement of Third Party Claims of Infringement. If a Third Party asserts that Patents, Know-How or other rights owned or controlled by it are infringed by the activities hereunder of either of the Parties, then defense of such claim (an “Infringement Claim”) will be managed in accordance with the provisions of Section 13.4 (Defense of Third Party Claims), with coordination and cooperation between the Defending Party and Assisting Party occurring via the Patent Coordinators. If either Party seeks to initiate a nullification, declaratory judgment, revocation, or opposition proceeding against any such Patents, Know-How or other rights in response to prospective or actual Third Party Claims of Infringement, the Parties will coordinate and cooperate in regard to such proceedings in accordance with the procedures set forth in Section 13.4 (Defense of Third Party Claims), with coordination and cooperation between the Defending Party and Assisting Party occurring via the Patent Coordinators.

Enforcement. Except as expressly set forth in this Section 10.8 (Enforcement), each Party will retain all its rights to control the enforcement of its own intellectual property. Amgen will have the first right (but not the obligation) to enforce the Program Intellectual Property against any Third Party that is developing, manufacturing, selling, or importing a product or service that competes with a Product; provided, that Partner will have the right to approve in writing any settlement of any claim, suit or action involving its intellectual property that admits the invalidity or unenforceability of its intellectual property or imposes on Partner restrictions or obligations. If Amgen fails to bring any such action or proceeding within forty-five (45) days (or twenty-five (25) days in the case of an action brought under the Biologics Price Competition and Innovation Act of 2009 (or any amendment or successor statute thereto) or within the time frame of any other relevant regulatory or statutory framework that may govern) of a request by Partner to do so (or, if sooner, five (5) days before the time limit, if any, set forth in the relevant laws and regulations for the filing of such actions), or earlier notifies Partner in writing of its intent not to bring such action or proceeding, then Partner will have the right (but not the obligation) to bring any such action or proceeding by counsel of its own choice; provided, that Amgen will have the right to approve in writing any settlement of any claim, suit or action involving its intellectual property that admits the invalidity or unenforceability of its intellectual property or imposes on Amgen restrictions or obligations. The non-enforcing Party will reasonably assist the enforcing Party with respect to any such enforcement in the Collaboration Territory, including, in the event that it is determined that the non-enforcing Party is an indispensable Party to such action, by being named as a Party in such action, and cooperate in any such action at the enforcing Party’s request. Without limiting the foregoing, the enforcing Party will keep the non-enforcing Party advised of all material communications, actual and prospective filings or submissions regarding such action, and will provide the non-enforcing Party copies of and an

opportunity to review and comment on any such material communications, filings and submissions (provided, that the enforcing Party will have the right to redact any manufacturing information and any information relating to any product other than Products from any such materials). All Recoveries will be retained by or paid to Amgen (whether Amgen is the enforcing Party or not), but to the extent such Recoveries were obtained with respect to a Product or a product that competes directly with a Product, the same shall be included in Net Revenues for the period in which such Recovery is made.

Patent Term Extensions. Each non-filing Party will provide reasonable assistance to the filing Party in connection with obtaining supplementary protection certificates, patent term extensions or similar protection for Patents (“Patent Extensions”) within the Product Intellectual Property or otherwise licensed or assigned hereunder as determined by the Patent Coordinators. To the extent reasonably and legally required to obtain any such Patent Extensions in a particular country, the non-filing Party will make available to the filing Party copies of all necessary documentation to enable the filing Party to use the same for the purpose of obtaining Patent Extensions in such country. Notwithstanding Section 10.6 (Prosecution and Maintenance) above, the Patent Coordinator for the Commercial Lead will have the right to make the final decision as to which Patents within the Amgen Intellectual Property, Partner Intellectual Property or Program Intellectual Property will be extended with respect to the Product(s) for which such Party is the Commercial Lead.

Trademarks.

other Party; (ii) not use such Product Trademarks or the other Party’s Housemarks in a way that might materially prejudice their distinctiveness or validity or the goodwill of the other Party therein; and (iii) not use any trademarks or trade names so resembling any of such Product Trademarks or the other Party’s Housemarks as to be likely to cause confusion or deception.

           Housemark Licenses.

  To Partner. Amgen hereby grants to Partner a [*], royalty-free license to use the Amgen Housemarks solely as set forth in the Promotional Materials and other materials provided to it by Amgen, and solely to develop, manufacture and commercialize Products in the Collaboration Scope in accordance with the Brand Plan, Country Plans and this Agreement.

  To Amgen. Partner hereby grants to Amgen a [*], royalty-free license to use the Partner Housemarks solely as set forth in the Promotional Materials and other materials provided to it by Partner, and solely to develop, manufacture and commercialize Products in the Collaboration Scope in accordance with the Brand Plan, Country Plans and this Agreement.

             Respect of Trademarks. Partner will not have, assert or acquire any right, title or interest in or to any Amgen Housemarks or the goodwill pertaining thereto, and Amgen will not have, assert or acquire any right, title or interest in or to any Partner Housemarks or the goodwill pertaining thereto, in each case by means of entering into or performing under this Agreement, except in each case for the limited licenses explicitly provided in this Agreement.

             Infringement. Each Party will monitor the Product Trademarks against infringing uses within the Collaboration Scope and will promptly notify the other Party of any infringement or threatened infringement of any of the Product Trademarks of which it becomes aware. The Patent Coordinators will determine what action, if any, to take in response to any such infringement or threatened infringement of any Product Trademark.

Confidentiality; Exceptions. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Parties agree that, during the Term and for [*] years thereafter, the receiving Party will keep confidential and will not publish or otherwise disclose or use for any purpose any and all information or materials related to the activities contemplated hereunder that is furnished to it by the other Party pursuant to this Agreement and is identified by the disclosing Party as confidential, proprietary or the like or that the receiving Party has reason to believe is confidential based upon its own similar information (collectively, “Confidential Information”). For clarity, except for rights expressly granted herein, both Parties will have no right to and will not utilize

any Confidential Information of the other Party for activities outside the Collaboration Scope or for activities related to products other than the Products. Notwithstanding the foregoing, Confidential Information will not include any information to the extent that it can be established by written documentation by the receiving Party that such information:

was obtained or was already known by the receiving Party or its Affiliates without obligation of confidentiality as a result of disclosure from a Third Party that the receiving Party did not know was under an obligation of confidentiality to the disclosing Party with respect to such information;

was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party through no act or omission of the receiving Party or its Affiliates in breach of this Agreement;

became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the receiving Party or its Affiliates in breach of this Agreement; or

was independently discovered or developed by the receiving Party or its Affiliates (without reference to or use of Confidential Information of the disclosing Party).

Authorized Disclosure. Except as expressly provided otherwise in this Agreement, each Party may use and disclose Confidential Information of the other Party solely as follows: (i) as reasonably necessary in conducting the activities contemplated under this Agreement; (ii) with respect to Confidential Information generated in the course of the activities conducted hereunder, to the extent pertaining specifically to a Product, for use by Amgen in connection with a Product in the Excluded Territory or disclosure by Amgen to a partner or licensee for use with respect to a Product in the Excluded Territory; (iii) to the extent such disclosure is to a Governmental Authority, as reasonably necessary in filing or prosecuting patent, copyright and trademark applications in accordance with this Agreement, prosecuting or defending litigation in accordance with this Agreement, complying with applicable governmental regulations with respect to performance under this Agreement, filing Regulatory Filings, obtaining Regulatory Approval or fulfilling post-approval regulatory obligations for a Product, or otherwise required by Applicable Law, provided, that if a Party is required by Applicable Law to make any such disclosure of the other Party’s Confidential Information it will, except where impracticable for necessary disclosures (for example, in the event of medical emergency), give reasonable advance notice to the other Party of such disclosure requirement and, in the case of each of the foregoing exceptions pursuant to this subsection (iii), will use its reasonable efforts to secure confidential treatment of such Confidential Information required to be disclosed; (iv) to advisors (including lawyers and accountants) on a need to know basis in support of the purposes of this Agreement, in each case under appropriate confidentiality provisions or professional standards of confidentiality substantially equivalent to those of this Agreement; and (v) to the extent mutually agreed to by the Parties. Neither Party will disclose Confidential Information of the other Party to its personnel or to an Affiliate except to the extent such personnel

or Affiliate needs to know such information for the performance of such Party’s activities hereunder.

Confidential Treatment of Terms and Conditions. The Parties agree that the terms and conditions of this Agreement will be Confidential Information of each Party, and such material terms and conditions will not be disclosed, except (i) as otherwise permitted under Section 11.2 (Authorized Disclosure) and (ii) if required by Applicable Law (including disclosure of a redacted version of this Agreement in a relevant SEC filing). Notwithstanding the foregoing, with respect to complying with the disclosure requirements of any Governmental Authority in connection with any required filing of this Agreement, the Parties will consult with one another concerning which terms of this Agreement will be requested to be redacted in any public disclosure of this Agreement, and in any event each Party will seek reasonable confidential treatment for any public disclosure by any such Governmental Authority.

Press Releases. Notwithstanding Section 11.3 (Confidential Treatment of Terms and Conditions), the Parties will issue a joint press release to announce the execution of this Agreement, which is attached hereto as the Press Release Schedule (or such other joint press release as may be mutually agreed upon in writing by the Parties) and is for use in responding to inquiries about this Agreement. Thereafter, Partner and Amgen may each disclose to Third Parties (including media interviews and disclosures to financial analysts) the information contained in such press release (but only such information) without the need for further approval by the other; provided, that such information is still accurate. Each Party will have the right to issue additional press releases and disclosures in regards to the terms of this Agreement only with the prior written consent of the other Party, such consent not to be unreasonably withheld (or as required to comply with Applicable Law). For any such proposed press release or disclosure, the disclosing Party will provide [*] business days’ notice to the other Party and will reasonably consider the other Party’s comments that are provided within [*] business days after such notice, or such shorter notice and comment periods as are reasonably required under the circumstances but not less than [*] business days.

Prior Agreement. This Agreement supersedes the Confidential Disclosure Agreement between Amgen and MedImmune, LLC (an Affiliate of AstraZeneca) dated September 14, 2011, as amended and supplemented, including any written requests thereunder with respect to information disclosed thereunder relating to the Products and activities related thereto. All confidential information exchanged between the Parties and their respective Affiliates under such agreement will be deemed Confidential Information of the disclosing Party disclosed hereunder and will be subject to the terms of this Agreement.

Publications and Program Information. Except as permitted pursuant to Section 3.5 (Clinical Trial Register), the Development Lead for a Product will have the sole right to publish and make scientific presentations with respect to such Product, and to issue press releases (except with respect to the terms of this Agreement, which is governed by Section 11.4 (Press Releases)) or make other public disclosures regarding any such Product (including with respect to its development, commercialization and regulatory matters), and the other Party will not do so without the Development Lead’s prior written

consent, except as required by Applicable Law; provided, that any publication or presentation to be made by the Development Lead that names the other Party will require the prior consent of the other Party. The Development Lead will keep the relevant committee or team informed of its general publication strategy and presentation calendar. The Development Lead will consider any reasonable comments regarding such strategy from the other Party. In addition, the Development Lead will deliver to the other Party a copy of any proposed written publication or outline of presentation to be made by the Development Lead with respect to any scientific data pertaining to a Product in the Collaboration Scope in advance of submission for publication or presentation at least [*] days in advance of submission (or, where a copy of such publication or presentation is not available at such time, a draft or outline of such publication or a description of such presentation), and the other Party will have the right to: (i) require a delay in submission of not more than [*] days to enable patent applications protecting the other Party’s rights in Inventions owned by such Party; and (ii) prohibit disclosure of any of its Confidential Information in any such proposed publication or presentation. Publications and presentations will be subject to policies mutually agreed by the Patent Coordinators to ensure appropriate protection of intellectual property rights. If there is any dispute between the Parties with regard to a proposed publication, presentation or other communication regarding this Agreement, such dispute shall be referred to the JSC for resolution (with the Development Lead for the Product having the final decision).

Disclaimer of Warranties. EXCEPT AS SET FORTH IN THIS ARTICLE 12 (REPRESENTATIONS AND WARRANTIES), PARTNER AND AMGEN EXPRESSLY DISCLAIM ANY AND ALL REPRESENTATIONS AND WARRANTIES, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, WITH RESPECT TO THE COLLABORATION, PRODUCT INTELLECTUAL PROPERTY, AMGEN HOUSEMARKS, PARTNER HOUSEMARKS, PRODUCT TRADEMARKS, THIS AGREEMENT, OR ANY OTHER SUBJECT MATTER RELATING TO THIS AGREEMENT, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR

PURPOSE, VALIDITY OR NONINFRINGEMENT OF INTELLECTUAL PROPERTY RIGHTS.

Limitation of Liability. NOTWITHSTANDING ANY OTHER PROVISION CONTAINED HEREIN, OTHER THAN TO THE EXTENT RESULTING FROM A PARTY’S BREACH OF ARTICLE 9 (DISTRACTING PRODUCTS) OR SECTION 11.1 (CONFIDENTIALITY; EXCEPTIONS), IN NO EVENT WILL PARTNER OR AMGEN BE LIABLE TO THE OTHER PARTY OR ANY OF ITS AFFILIATES FOR ANY CONSEQUENTIAL, INCIDENTAL, INDIRECT, SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES (INCLUDING LOST PROFITS, BUSINESS OR GOODWILL) SUFFERED OR INCURRED BY SUCH OTHER PARTY OR ITS AFFILIATES IN CONNECTION WITH A BREACH OR ALLEGED BREACH OF THIS AGREEMENT. THE FOREGOING SENTENCE WILL NOT LIMIT THE OBLIGATIONS OF EITHER PARTY TO INDEMNIFY THE OTHER PARTY FROM AND AGAINST SUCH DAMAGES AS ARE AWARDED TO A THIRD PARTY WITH RESPECT TO THIRD PARTY CLAIMS UNDER SECTION 13.1 (INDEMNITY BY PARTNER) OR SECTION 13.2 (INDEMNITY BY AMGEN).

INDEMNIFICATION AND INSURANCE

Indemnity by Partner. Partner will defend, indemnify, and hold harmless Amgen, its Affiliates, and their respective directors, officers, employees, agents and representatives (collectively, “Amgen Indemnitees”), at Partner’s cost and expense, from and against any and all liabilities, losses, costs, damages, fees or expenses (including reasonable legal expenses and attorneys’ fees) (collectively, “Losses”) arising out of any Third Party Claims brought against any Amgen Indemnitee to the extent such Losses result from: [*]. The indemnification obligations under this Section 13.1 (Indemnity by Partner) exclude Losses to the extent they arise from [*] below in Section 13.2 (Indemnity by Amgen).

Indemnity by Amgen. Amgen will defend, indemnify, and hold harmless Partner, its Affiliates, and their respective directors, officers, employees, agents and representatives (collectively, “Partner Indemnitees”), at Amgen’s cost and expense, from and against any and all Losses arising out of any Third Party Claims brought against any Partner Indemnitee to the extent such Losses result from: [*]. The indemnification obligations under this Section 13.2 (Indemnity by Amgen) exclude Losses to the extent they arise from [*] above in Section 13.1 (Indemnity by Partner).

Claim for Indemnification. Whenever any Third Party Claim or Loss arises for which a Partner Indemnitee or an Amgen Indemnitee (the “Indemnified Party”) may seek indemnification under this Article 13 (Indemnification and Insurance), the Indemnified Party will promptly notify the other Party (the “Indemnifying Party”) of the Third Party Claim or Loss; provided, that the failure by an Indemnified Party to give such notice will not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that the Indemnifying Party is actually prejudiced as a result of such

failure. The Indemnifying Party will have exclusive control of the defense and settlement of all Third Party Claims for which it is responsible for indemnification and will assume defense thereof at its own expense promptly upon notice of such Third Party Claim. In no event will the Indemnifying Party settle any Third Party Claim without the prior written consent of the Indemnified Party if such settlement (x) does not include a complete release from liability on such Third Party Claim, or (y) includes any admission of wrongdoing by the Indemnified Party or that any intellectual property or proprietary right of the Indemnified Party is invalid or unenforceable. The Indemnified Party will have the right to employ separate counsel at the Indemnifying Party’s expense and to control its own defense of the applicable Third Party Claim if: (i) there are or may be legal defenses available to the Indemnified Party that are different from or additional to those available to the Indemnifying Party; or (ii) in the reasonable opinion of counsel to the Indemnified Party, a conflict or potential conflict exists between the Indemnified Party and Indemnifying Party that would make such separate representation advisable.

Defense of Third Party Claims. Except as otherwise provided in Section 13.3 (Claim for Indemnification), each Party (such Party referred to as the “Defending Party”) will have the sole right, but not the obligation, to defend against any Third Party Claims made against it with respect to its activities hereunder; provided, that any Third Party Claims relating to a nullification, declaratory judgment, opposition or revocation proceeding against any Product Intellectual Property will be governed by the provisions of Section 10.8 (Enforcement). Each Party will notify the other Party (the “Assisting Party”) as promptly as practicable if any such Third Party Claim is commenced or threatened against it, including any Infringement Claim. The Assisting Party will reasonably assist the Defending Party and cooperate in any such litigation at Defending Party’s reasonable request. Without limiting the foregoing, the Defending Party will keep the Assisting Party advised of all material communications, actual and prospective filings or submissions regarding such action, and will provide the Assisting Party copies of and an opportunity to review and comment on any such communications, filings and submissions; provided, that each Party will have the right to redact from any information disclosed to the other hereunder any information relating to a product other than a Product or relating to the manufacture of a Product. The Defending Party will control the defense and settlement of Third Party Claims, with the costs thereof being included in General Costs, to the extent provided in Section 1.65.4. The Defending Party will not settle such Third Party Claim without the prior written consent of the other Party (such consent not to be unreasonably withheld), unless such settlement: [*]. In the event that a Third Party Claim is brought against both of the Parties (a “Joint Claim”), then the Parties will determine whether to defend against such Joint Claim, which of the Parties should be the Defending Party or whether the Parties should jointly control such defense and the strategy for such defense. In the case of an Infringement Claim, the coordination and cooperation set forth in this Section 13.4 (Defense of Third Party Claims) will be accomplished via the Patent Coordinators. This Section 13.4 (Defense of Third Party Claims) will not apply to employment or similar personnel-related claims.

Insurance. Each of the Parties will, at their own

respective expense (and not subject to cost sharing hereunder) procure and maintain during the Term, insurance policies adequate to cover their obligations hereunder and consistent with the normal business practices of prudent pharmaceutical companies of similar size and scope (or reasonable self-insurance sufficient to provide materially the same level and type of protection). Such insurance will not create a limit to either Party’s liability hereunder.

Term. This Agreement will become effective on the Effective Date and will continue during the Term.

Termination for Convenience.

Either Party will have the right to terminate this Agreement, either in whole or on a Product-by-Product basis, by providing the other Party with [*] prior written notice (or, after First Commercial Sale of a Product, [*] prior written notice with respect to such Product); provided, that a notice of termination with respect to a particular Product may only be provided after the Continued Development Meeting for such Product has occurred and a notice of termination with respect to the Agreement in whole may only be provided after the Continued Development Meetings for all Products have occurred.

[*].

Termination for Breach. In the event of a material breach of this Agreement, the non-breaching Party will have the right to terminate this Agreement, either in whole or (if such breach solely applies to a specific Product(s)) with respect to the applicable Product(s). The non-breaching Party may terminate this Agreement, whether in its entirety or on a Product-by-Product basis (as applicable), by written notice to the breaching Party, which notice will specify the nature of such breach in reasonable detail. Such termination will become effective on the date that is [*] days after the delivery thereof to the breaching Party (or, in the case of a failure to pay amounts due hereunder, [*] days) unless, during the [*] day (or [*] day) period after delivery of such notice to the breaching Party, the breaching Party has cured such breach to the reasonable satisfaction of the non-breaching Party. Notwithstanding the foregoing, in the event of a good faith dispute as to whether performance has been made by either Party pursuant to this Agreement, including any good faith dispute as to payments due under this Agreement, the relevant cure period with respect thereto will be tolled pending resolution of such dispute in accordance with the applicable provisions of this Agreement; provided, that if such dispute relates to payment, the cure period will only apply with respect to payment of disputed amounts, and not with respect to undisputed amounts.

Termination for Insolvency. Either Party will have the right to terminate this Agreement immediately upon written notice, if: (i) the other Party becomes insolvent; (ii) the other Party files a petition in bankruptcy, or if an involuntary petition in bankruptcy is filed against the other Party and such involuntary petition is not dismissed within seventy-five (75) days and the other Party (a) fails to assume this Agreement in any such bankruptcy proceeding

within thirty (30) days after filing or (b) assumes and assigns this Agreement to a Third Party; or (iii) a receiver or guardian has been appointed for the other Party who is not discharged within seventy-five (75) days after appointment.

Termination for Challenge. Either Party will have the right to terminate this Agreement on a Product-by-Product basis by written notice to the other Party, if such other Party, its Affiliates or licensees bring or join any challenge to the validity or enforceability of (i) if Amgen is the challenging Party, any Partner Intellectual Property or any Program Intellectual Property, in each case as and to the extent such Partner Intellectual Property or Program Intellectual Property applies to the Product in the Collaboration Scope that is the subject of the termination notice; and (ii) if Partner is the challenging Party, any Amgen Intellectual Property (or any intellectual property corresponding to any such Amgen Intellectual Property in the Excluded Territory) or any Program Intellectual Property, in each case as and to the extent such Amgen Intellectual Property or Program Intellectual Property applies to a Product in the Collaboration Scope that is the subject of the termination notice. Notwithstanding the foregoing, nothing in this Section 14.5 (Termination for Challenge) will either: (a) prevent either Party from asserting any defense or counterclaim in an action for infringement of intellectual property, brought against such Party or its Affiliates, or any Third Party that such Party or any of its Affiliates is obligated to indemnify, or responding in any other manner to such an action for infringement; or (b) allow a Party to terminate this Agreement in the event the other Party asserts any such defense or counterclaim or otherwise responds in any such action for infringement.

Relationship of the Parties. Each Party is an independent contractor under this Agreement. Nothing contained herein will be deemed to create an employment, agency, joint venture or partnership relationship between the Parties or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party. The Parties will operate their own businesses separately and independently and they will hold themselves out as, act as, and constitute independent

contractors in all respects and not as principal and agent, partners or joint venturers. Neither party will have any express or implied power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.

Severability. To the fullest extent permitted by Applicable Law, the Parties waive any provision of Applicable Law that would render any provision in this Agreement invalid, illegal or unenforceable in any respect. If any provision of this Agreement is held to be invalid, illegal or unenforceable, in any respect or to any extent, then in such respect and to such extent such provision will be given no effect by the Parties and will not form part of this Agreement. To the fullest extent permitted by Applicable Law, all other provisions of this Agreement will remain in full force and effect and the Parties will use their commercially reasonable efforts to negotiate a provision in replacement of the provision held invalid, illegal or unenforceable that is consistent with Applicable Law and achieves, as nearly as possible, the original intention of the Parties.

Third Party Beneficiaries. Except as expressly provided with respect to Amgen Indemnitees or Partner Indemnities in Article 13 (Indemnification and Insurance), there are no Third Party beneficiaries intended hereunder and no Third Party will have any right or obligation hereunder.

Waivers and Modifications. The failure of any Party to insist on the performance of any obligation hereunder will not be deemed to be a waiver of such obligation. Waiver of any breach of any provision hereof will not be deemed to be a waiver of any other breach of such provision or any other provision on such occasion or any other occasion. No waiver, modification, release or amendment of any right or obligation under or provision of this Agreement will be valid or effective unless in writing and signed by all Parties hereto.
