“Combination Product”), the Net Sales of such Product for the purpose of calculating royalties and sales-based milestones owed under this Agreement for sales of such Product,
shall be determined as follows: first, Astellas shall determine the actual Net Sales of such Combination Product (using the above provisions) and then such amount shall be multiplied by the fraction A/(A+B), where A is the invoice price of the
Product, if sold separately, and B is the total invoice price of any other active pharmaceutical molecule or delivery device in the combination if sold separately. If any other active pharmaceutical molecule or delivery device in the combination is
not sold separately, Net Sales shall be calculated by multiplying actual Net Sales of such Combination Product by a fraction A/C where A is the invoice price of the Product if sold separately, and C is the invoice price of the Combination Product.
If neither the Product nor any other active pharmaceutical molecule or delivery device in the Combination Product is sold separately, the adjustment to Net Sales shall be determined by the Parties in good faith to reasonably reflect the fair market
value of the contribution of the Product in the Combination Product to the total fair market value of such Combination Product.

length terms (which has the effect of reducing the invoiced amount below what it would have been in the absence of such non-monetary consideration), for purposes of calculating the Net Sales under this Agreement, such Product shall be deemed to be
sold exclusively for cash at the average Net Sales price charged to Third Parties for cash sales in such country during the applicable reporting period (or if there were only de minimis cash sales in such country, at the fair market value as
determined by comparable markets). Notwithstanding the foregoing, Net Sales shall not include amounts (whether actually existing or deemed to exist for purposes of calculation) for Products distributed for use in Clinical Trials or as Samples. 

Net Sales will be calculated on an accrual basis, in a manner consistent with Astellas’s internal accounting policies, as consistently
applied. To the extent any accrued amounts used in the calculation of Net Sales are estimates, such estimates shall be trued-up in accordance Astellas’s internal accounting policies, as consistently applied, and Net Sales and related payments
under this Agreement shall be reconciled as appropriate.

 ARTICLE 3 

DEVELOPMENT 

3.1 Overview. The Parties intend and agree to undertake a joint development program to further Develop one or more Collaboration
Molecules and Products (such program, the “Development Program”). The initial objective of the Development Program shall be the Development of an MDV3100 Product in support of obtaining Regulatory Approvals therefor in each of the
Shared Territory, the EU and Japan. Each applicable Joint Development Plan (as amended from time to time), and all Non-Clinical Studies and Clinical Trials under such plan, shall be designed and implemented in furtherance of such objective. 

3.2 Joint Development Plan. 

(a) General. All Development of any given Product pursuant to this Agreement for the Shared Territory, the EU, and/or Japan shall be
conducted pursuant to a joint development plan and budget (the “Joint Development Plan”) that describes (i) the proposed overall program of Development for the applicable 

  
 [*] = Certain confidential

 27 








 
Product in the Shared Territory, the EU and Japan, including Clinical Trials and Nonclinical Studies and, regulatory plans and other elements of obtaining Regulatory Approval(s) in each
applicable country or jurisdiction; (ii) the anticipated start dates and data availability dates of such Clinical Trials and Nonclinical Studies, and anticipated timelines for filing of applications for Regulatory Approvals in the Shared
Territory, the EU and Japan; (iii) the respective roles and responsibilities of each Party in connection with such activities; and (iv) a detailed budget for all such activities in the Shared Territory. In the event of any inconsistency
between the Joint Development Plan and this Agreement, the terms of this Agreement shall prevail. 
 (b) Initial Joint Development
Plan. The initial Joint Development Plan is attached hereto as Exhibit 3.2(b) (the “Initial Joint Development Plan”). 

(c) Amendments to the Joint Development Plan. On an annual basis (no later than [*] of the preceding calendar year), or more often as
the Parties deem appropriate, the JDC shall prepare amendments to the then-current Joint Development Plan(s), including the corresponding Joint Development Budget(s), for approval of the JSC. Each such amended Joint Development Plan shall specify,
with a level of detail according to Astellas’s standard practices, the items described in Section 3.2(a). Such amended Joint Development Plan shall cover the next calendar year (and additional periods as reasonably determined by the
Parties) and the Joint Development Budget included therein shall appropriately itemize the costs separately for each Product. Such updated and amended Joint Development Plan shall reflect any changes, re-prioritization of studies within,
reallocation of resources with respect to, or additions to the then-current Joint Development Plan. In addition, the JDC may prepare amendments for approval by the JSC to the Joint Development Plan (including the corresponding Joint Development
Budget) from time to time during the calendar year in order to reflect changes in such plan or budget for such calendar year, in each case, in accordance with the foregoing. For the avoidance of doubt and without limitation, both Parties shall have
the right to propose to the JDC any studies of the MDV3100 Product not then part of a Joint Development Plan, or the expansion of development of the MDV3100 Product to include any new indication(s) within the Field, or the development of any
Collaboration Molecule other than MDV3100. Once approved by the JSC, the amended annual Joint Development Plan (including the corresponding Joint Development Budget) shall become effective for the applicable period on the date approved by the JSC
(or such other date as the JSC shall specify). Any JSC-approved amended Joint Development Plan (including the corresponding Joint Development Budget) shall supersede the previous Joint Development Plan (including the corresponding Joint Development
Budget) for the applicable period. 
 (d) Operational Responsibilities for Development. Unless the Parties agree in writing upon an
alternate allocation of responsibility, the Parties shall have the following rights and obligations with respect to the operational responsibilities under each Joint Development Plan, which rights shall be exercised and obligations shall be
fulfilled in accordance with the last sentence of Section 3.1: 
 (i) [*]. Operational responsibility for all [*] and [*]
designed to support Regulatory Approvals in [*] shall be allocated between the Parties as set forth in the Joint Development Plan. 

(ii) Other Countries. Except as otherwise provided in any Joint Development Plan, [*] shall be responsible for all [*] and [*]
to the extent designed to support Regulatory Approvals in countries in the Territory other than [*]. 
 (e) Development Decision-Making.
Except as otherwise expressly provided in this Agreement, all matters regarding the Development Program shall be decided by [*], subject to the provisions of Sections [*]. 

3.3 Development Costs. Medivation shall be responsible for fifty percent (50%) and Astellas shall be responsible for fifty percent
(50%) of all Joint Development Costs, except with respect to costs of Non-Clinical Studies and Clinical Trials (including the costs of drug product or comparator drug for use therein) and the costs of CMC Activities (a) contemplated in the
Joint Development Plan and (b) reasonably considered to be required for receipt of Regulatory Approvals for Products in the Shared Territory and either or both of the EU and Japan, for which Medivation shall be responsible for one-third
(1/3) and Astellas shall be responsible for two-thirds (2/3).

Prior to the initiation of any Non-Clinical Study, Clinical Trial or CMC Activity commencing after the Effective Date supporting Development of Products with respect to the Shared Territory and
either or both of the EU and Japan, the Parties shall agree whether the costs of such study or activity are to be shared equally by the Parties or allocated pursuant to clause (b) above. Astellas shall be responsible for one hundred percent
(100%) of all Development Costs for the Licensed Territory if such costs are not included in Joint Development Costs. The allocation of costs for the Non-Clinical Studies and Clinical Trials contained in the Initial Joint Development Plan shall
be as set forth therein. Notwithstanding the amounts allocated to Development activities in the applicable Joint Development Plan, for any calendar year, Astellas and Medivation shall each be permitted to recover Joint Development Costs with respect
to such Party’s Development activities for such year covered in the Joint Development Budget in excess of the amount allocated therein (x) by up to [*] of the amount so allocated, but solely to the extent such overage was outside the
reasonable control of the applicable Party and was not attributable to a failure by the applicable Party to use commercially reasonable efforts to adequately supervise any Third Party performing such activities or (y) with the unanimous
approval of the JDC, which approval may be granted either in advance of such costs being incurred or retroactively. The Parties shall reconcile the Joint Development Costs they have incurred to reflect the foregoing allocation of Joint Development
Costs according to the procedures in Section 9.2 or Section 9.3, as applicable. 
 3.4 Diligence; Standards of Conduct.

 (a) The Parties agree to use Diligent Efforts to Develop and obtain Regulatory Approval for an MDV3100 Product throughout the
Territory, it being understood that the use of Diligent Efforts to carry out the tasks assigned to it under the Joint Development Plan with respect to any such Product satisfy the Party’s obligation with respect to such Product for the [*].
Each Party shall use Diligent Efforts to carry out the tasks assigned to it under the Joint Development Plan, including with respect to MDV3100 Products and any other Products selected for Development under the Joint Development Plan, in a timely
and effective manner. Astellas and Medivation shall provide financial support for the Development of Products as provided in this Agreement, subject to and in accordance with any applicable budgets therefor. 

(b) Each Party shall conduct its activities under the Joint Development Plan in a good scientific manner and in compliance in all
material respects with Applicable Law. Each Party agrees that (i) each Clinical Trial conducted pursuant to the Joint Development Plan that is required to be posted pursuant to Applicable Law or applicable industry codes, including the PhRMA
Code, on clinicaltrials.gov or any other similar registry shall be so posted, and (ii) all results of such Clinical Trials that are necessary for obtaining a Regulatory Approval for a Product in the Shared Territory shall be posted on
clinicalstudyresults.org and on any other registry with requirements consistent with the registration and publication guidelines of the International Committee of Medical Journal Editors, to the extent required. The responsibility for such posting
shall be allocated between the Parties by the JDC. All data and Information posted on clinicaltrial.gov, clinicalstudyresults.org or any other registry pursuant to this Section 3.4(b) shall be subject to prior review and authorization pursuant
to Section 13.5(c) as if such posting were a Publication. 
 3.5 Development Records and Reports. Each Party shall maintain
complete and accurate records (in the form of technical notebooks and/or electronic files where appropriate) of all work conducted by it under the Joint Development Plan and all Information resulting from such work. Such records shall fully and
properly reflect all work done and results achieved in the performance of the Joint Development Plan in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes. Each Party shall have the right to receive copies
of such records maintained by the other Party, including in electronic format if maintained in such format, at reasonable times to the extent reasonably necessary to perform obligations or exercise rights under this Agreement, and to obtain access
to originals to the extent needed for patent or regulatory purposes. 
 3.6 Subcontracts. Each Party may perform any of its
Development Program obligations under this Agreement through one or more subcontractors or consultants, provided that (a) such Party remains responsible for the work allocated to, and payment to, such subcontractors and consultants to the same
extent it would if it had done such work itself; (b) the subcontractor or consultant undertakes in writing commercially reasonable obligations of confidentiality and non-use regarding Confidential Information and Protected Product Information,

4.2 Product Withdrawals and Recalls.  

(a) Shared Territory. If (i) any Regulatory Authority threatens, initiates or advises any action to remove any Product from the
market in the Shared Territory or requires or advises Medivation, Astellas, or any of their respective Affiliates or Sublicensees to distribute a “Dear Doctor” letter or its equivalent regarding use of such Product in the Shared Territory,
or (ii) either Party determines that an event, incident or circumstance has occurred that may result in the need for a recall or market withdrawal in the Shared Territory, then in each case ((i) or (ii)) Medivation or Astellas, as applicable,
shall notify the other Party of such event or determination immediately, and in any event within [*] (or sooner if required by law) after such Party becomes aware of the event or makes such determination. The Party who is the then-holder of the
Regulatory Approval for the Product at issue shall, to the extent practicable, endeavor to discuss and agree with the other Party upon whether to recall or withdraw the Product in the Shared Territory; provided, however, that if such discussion is
not practicable or if the Parties fail to agree within an appropriate time period (recognizing the exigencies of the situation), then the Party who is the then-holder of the Regulatory Approval for the Product at issue shall decide whether to recall
or withdraw such Product in the Shared Territory. Any recall expenses with respect to Products within the Shared Territory shall be treated as Joint Development Costs or Joint Commercialization Costs, as applicable. 

(b) Licensed Territory. If (i) any Regulatory Authority threatens, initiates or advises any action to remove any Product from the
market in the Licensed Territory or requires or advises Medivation, Astellas, or any of their respective Affiliates or Sublicensees to distribute a “Dear Doctor” letter or its equivalent regarding use of such Product in the Licensed
Territory, or (ii) Astellas determines that an event, incident, or circumstance has occurred that may result in the need for a recall or market withdrawal in the Licensed Territory, then in each case ((i) or (ii)) Medivation or Astellas, as
applicable, shall, to the extent practicable, notify the other Party of such event or determination immediately, and in any event within [*] (or sooner if required by law) after such Party becomes aware of the event or makes such determination.
Astellas shall, to the extent practicable, endeavor to discuss and agree with Medivation upon whether to recall or withdraw the Product in the Licensed Territory; provided, however, that if such discussion is not practicable or if the Parties fail
to agree within an appropriate time period (recognizing the exigencies of the situation), then Astellas shall decide whether to recall or withdraw such Product in the Licensed Territory. Astellas shall be responsible, at its sole expense, for
conducting any recalls or taking such other necessary remedial action in the Licensed Territory, except to the extent that the recall or withdrawal is attributable to the negligence, breach or intentional misconduct of Medivation or any of its
Affiliates or subcontractors, in which event Medivation shall bear such costs to the extent of its or its Affiliate’s or subcontractor’s responsibility. 

4.3 Safety Agreement. Promptly after the Effective Date, but in any event no later than the date of initiation of a Clinical Trial by
Astellas in the Territory, the Parties shall enter into a safety agreement governing the Parties’ respective obligations with respect to allocation of responsibilities for reporting to the other Party and appropriate Regulatory Authorities
adverse events, complaints, and other safety-related matters. Medivation shall be responsible for creation and maintenance of the global safety database for Products until [*]; at the time of [*], Astellas shall become responsible for maintenance of

ARTICLE 5 
 MEDICAL AFFAIRS
ACTIVITIES 
 5.1 Overview. The Parties agree to collaborate with respect to the Medical Affairs Activities in
support of Products in the Field in the Shared Territory as provided in this Article 5 under the direction of the JMAC, and pursuant to the Joint Medical Affairs Plan applicable to each Product. Astellas shall have the sole right and responsibility
for Medical Affairs Activities in support of Products in the Field in the Licensed Territory in accordance with this Agreement and as provided in this Article 5. 

5.2 Joint Medical Affairs Plan. As further described in this Section 5.2, the Medical Affairs Activities in support of each
Product in the Shared Territory shall be described in a comprehensive plan (each such plan, a “Joint Medical Affairs Plan”) that describes the pre-launch activities, launch activities and subsequent Medical Affairs Activities for
such Product in the Shared Territory (including without limitation anticipated Voluntary Phase 4 Clinical Trials, scientific presentations and publications, and medical education), key tactics and strategies for implementing those activities,
the relative responsibilities of the Parties and the associated budget for such activities (each such included budget, a “Joint Medical Affairs Budget”). The Parties shall agree upon the initial Joint Medical Affairs Plan (including
the corresponding Joint Medical Affairs Budget), which shall be approved by the JMAC, no later than [*] after the Effective Date. All Joint Medical Affairs Plans, including corresponding Joint Medical Affairs Budgets, with respect to a Product in
the Shared Territory and subsequent revisions thereto will contain such information as the JMAC believes necessary for the successful medical affairs support of such Product in the Shared Territory, both pre- and post-launch, and shall generally
conform to the level of detail utilized by Astellas in preparation of its own plans for product Medical Affairs Activities. On an annual basis (no later than [*] of the preceding calendar year), or more often as the Parties deem appropriate, the
JMAC shall prepare amendments to the then-current Joint Medical Affairs Plan(s), including the corresponding Joint Medical Affairs Budget(s). In the event of any inconsistency between a Joint Medical Affairs Plan and this Agreement, the terms of
this Agreement shall prevail. 
 5.3 Medical Affairs Reports for the Shared Territory. Each Party shall keep the JMAC fully informed
regarding the progress and results of Medical Affairs Activities in support of Products in the Shared Territory, including an annual review of achievements versus plans (as such plans are set forth in the Joint Medical Affairs Plan(s)). 

5.4 Medical Affairs Updates for the Licensed Territory. Astellas shall provide informational updates to the JMAC of its planned Medical
Affairs Activities and recent results in support of Products in the Licensed Territory on an annual basis; and shall respond in a timely fashion to any reasonable requests of Medivation with respect to such activities and results. Astellas will
consider in good faith Medivation’s input, provided that Astellas shall have final decision making authority with respect to Medical Affairs Activities in support of Products in the Licensed Territory. 

5.5 Medical Affairs Costs. Astellas shall be solely responsible for all costs and expenses incurred by or on behalf of Astellas for
Medical Affairs Activities in support of Products in the Licensed Territory if such costs are not included in the Joint Medical Affairs Costs. Medivation shall be responsible for fifty percent (50%) and Astellas shall be responsible for fifty

 ARTICLE 6

 COMMERCIALIZATION 

6.1 Overview. The Parties agree to collaborate with respect to the Commercialization of Products in the Field in the Shared Territory
as provided in this Article 6 under the direction of the JCC, and pursuant to the Joint Commercialization Plan applicable to each Product. Astellas shall have the sole right and responsibility for Commercializing Products in the Field in the
Licensed Territory in accordance with this Agreement and as provided in this Article 6. 
 6.2 Joint Commercialization Plan. 

 (a) As further described in this Section 6.2, the tactics and strategy for the Commercialization of each Product in the
Shared Territory shall be described in a comprehensive plan (each such plan, a “Joint Commercialization Plan”) that describes the pre-launch, launch and subsequent Commercialization of such Product in the Shared Territory (including
without limitation anticipated activities relating to messaging, branding, Pricing Matters, advertising, planning, marketing, sales force training and allocation, and Distribution Matters), key tactics and strategies for implementing those
activities and the associated budget for such activities (each such included budget, a “Joint Commercialization Budget”). If Astellas believes any individual Commercialization Cost that it expects or plans to incur with respect to
the Licensed Territory will also reasonably benefit the Shared Territory, Astellas may propose that a portion of such Commercialization Cost be allocated in the applicable Joint Commercialization Budget to the Shared Territory, and Medivation shall
consider that request reasonably and in good faith. No such Commercialization Cost may be allocated in whole or in part to the Shared Territory without the express written consent of Medivation (it being understood that each of the Parties shall be
deemed to have consented expressly in writing that any such Commercialization Costs included as part of the Joint Commercialization Budget be allocated to the Shared Territory to the extent appearing in such budget). 

(b) Within [*] after the Effective Date, the Parties shall agree upon the initial Joint Commercialization Plan (including the initial
Joint Commercialization Budget), following which the JCC shall approve such initial Joint Commercialization Plan. Subject to Section 6.5, each Joint Commercialization Plan shall allocate the responsibilities of the Parties for the activities
under the plan in an equitable fashion taking into account the Parties’ respective capabilities and the Medivation Promotional Share elected by Medivation in accordance with Section 6.9 (it being understood that Medivation shall be
assigned to perform that proportion of Details in the Joint Commercialization Plan that equals the Medivation Promotional Share). All Joint Commercialization Plans, including the corresponding Joint Commercialization Budgets, with respect to a
Product in the Shared Territory and subsequent revisions thereto will contain such information as the JCC believes necessary for the successful Commercialization of such Product in the Shared Territory, both pre- and post-launch, and shall generally
conform to the level of detail utilized by Astellas in preparation of its own product Commercialization plans. On an annual basis (no later than [*] of the preceding calendar year), or more often as the Parties deem appropriate, the JCC shall
prepare amendments to the then-current Joint Commercialization Plan(s), including the corresponding Joint Commercialization Budgets. In the event of any inconsistency between a Joint Commercialization Plan and this Agreement, the terms of this
Agreement shall prevail. Each Party shall conduct its activities under the Joint Commercialization Plan in compliance in all material respects with Applicable Law.

the Commercialization of Products in the Licensed Territory except for such costs that are included in Joint Commercialization Costs. Medivation shall be responsible for fifty percent (50%) and Astellas shall be responsible for fifty percent
(50%) of Joint Commercialization Costs. Notwithstanding the amounts allocated to Commercialization activities in the Shared Territory in the applicable Joint Commercialization Budget, for any calendar year, Astellas and Medivation shall each be
permitted to recover Joint Commercialization Costs with respect to such Party’s Commercialization activities for such year covered in the Joint Commercialization Budget in excess of the amount allocated therein (a) by up to [*] of the
amount so allocated, but solely to the extent such overage was outside the reasonable control of the applicable Party and was not attributable to a failure by the applicable Party to use commercially reasonable efforts to adequately supervise any
Third Party performing such activities or (b) with the unanimous approval of the JCC, which approval may be granted either in advance of such costs being incurred or retroactively. Astellas and Medivation shall reconcile Joint Commercialization
Costs incurred by each Party through the procedures in Section 9.2 or Section 9.3, as applicable. 
 6.5 Sales and
Distribution. 
 (a) Astellas shall be solely responsible for handling all returns, recalls, order processing, invoicing and

the Shared Territory. If Medivation exercises such option, Medivation shall have the right to provide up to [*], and the obligation to provide at least [*], of the Promotion Effort for each Product in the Shared Territory, with the exact percentage
within such range (the “Medivation Promotional Share”) to be determined by Medivation in accordance with the remainder of this Section 6.9(a). Medivation shall initially specify the level of Medivation Promotional Share (which
level shall be in accordance with the previous sentence) when it exercises the Co-Promotion Option. Unless otherwise approved by the JCC, such level of Medivation Promotional Share shall remain in effect for the balance of the calendar year in which
the First Commercial Sale of the Product in the Shared Territory occurs, and the first full calendar year thereafter. Commencing with the second full calendar year following the First Commercial Sale of the Product in the Shared Territory, and
annually thereafter, Medivation may change the level of Medivation Promotional Share with respect to such Product, upon no less than [*] notice to the JCC, provided that the Medivation Promotional Share for any calendar year may not vary by more

obligations of confidentiality and non-use regarding Confidential Information and Protected Product Information that are substantially the same as those undertaken by the Parties with respect to
Confidential Information pursuant to Article 13 hereof, except that [*] may be [*] as can reasonably be [*], but in any case [*] shall have a [*] that is [*]; (c) the Third Party manufacturer agrees in writing to assign or license back (with
the right to sublicense) all intellectual property with respect to Collaboration Molecules or Products developed in the course of performing any such Manufacturing to the Party retaining such Third Party manufacturer (except that such Party shall

 7.10 Transfer of Manufacturing Technology. From time to time
Medivation shall disclose and transfer to Astellas or any of its Affiliates, Sublicensees or a Third Party manufacturer designated by Astellas all Medivation Know-How and all Joint Know-How Controlled by Medivation or its Affiliate as of the
Effective Date and during the Term (to the extent not previously transferred or disclosed to Astellas, its Affiliate, Sublicensee or Third Party manufacturer, as applicable) that is reasonably necessary or useful for Astellas or such Third Party
manufacturer (as appropriate) to Manufacture the MDV3100 Product, including the Initial MDV3100 Product and any [*] MDV3100 Product. Medivation shall provide such assistance and cooperation to Astellas or its designee(s) to permit Astellas or the
designee(s), as applicable, to be qualified by all required Regulatory Authorities as a manufacturer(s) of each Product as soon as practicable. Medivation shall perform this technology transfer with respect to the Initial MDV3100 Product reasonably
in advance of Astellas’s assumption of operational responsibility for commercial supply therefor (or earlier if requested by Astellas), and shall perform this technology transfer with respect to each [*] MDV3100 Product reasonably in advance of
[*] therefor (or earlier if requested by Astellas). In addition, Medivation shall perform or renew this technology transfer and qualification with respect to any Product at Astellas’s request, and from time to time to the extent that Medivation
acquires or develops new data, processes, know-how, or other Information relevant to the Manufacture of a Product. For the avoidance of doubt, nothing in this Section 7.10 with respect to Medivation’s obligation to transfer manufacturing
know-how to Astellas shall limit Medivation’s right to use any Manufacturing know-how pursuant to the sublicense granted to Medivation in Section 8.2 in order to fulfill Medivation’s obligations in accordance with the Joint
Manufacturing Plan. The reasonable costs and expenses incurred by Medivation in accordance with the Joint Manufacturing Plan, including without limitation any internal personnel costs, in carrying out such transfer shall be shared as a Joint
Development Cost. The Parties shall work together to effectuate the contemplated transfer as expeditiously and efficiently as reasonably possible and in a manner to meet the Development and Commercialization timelines in the Joint Manufacturing

transferred pursuant to Section 7.10 in accordance with the licenses granted in Section 8.1 and solely for the purpose of Manufacturing or otherwise Exploiting Products for uses permitted under this Agreement, and for no other purpose
(provided, however, that, for the avoidance of doubt, such restriction shall not apply to the extent of any applicable exclusions in Article 13). Astellas acknowledges and agrees that Medivation may condition its agreement to transfer any Medivation
Know-How to a Third Party manufacturer on the execution of a confidentiality agreement between such Third Party manufacturer and Medivation in which the Third Party manufacturer undertakes commercially reasonable obligations of confidentiality and
non-use regarding Confidential Information and Protected Product Information, that are substantially the same as those undertaken by the Parties with respect to Confidential Information pursuant to Article 13, except that [*] may be [*] as can
reasonably be [*], but in any case [*] shall have [*] that is [*].

with the prior written consent of Medivation, provided that a sublicense may be granted without such consent (but with prompt written notice to Medivation) (A) to a Third Party solely with respect to a country of the Licensed Territory (other
than [*]) if Astellas [*] in such country or Astellas [*] to Commercialize the Product by its Affiliate in such country or (B) to a subcontractor to perform Astellas’s assigned responsibilities under this Agreement or any Joint Development
Plan, Joint Manufacturing Plan, Joint Medical Affairs Plan and/or Joint Commercialization Plan. The (sub)licenses granted by Astellas to Medivation in Section 8.2 may be sublicensed by Medivation to a subcontractor to perform Medivation’s
assigned responsibilities under this Agreement or any Joint Development Plan, Joint Manufacturing Plan, Joint Medical Affairs Plan and/or Joint Commercialization Plan, upon prompt written notice to Astellas. Nothing herein is intended to permit use
of a Third Party to provide Sales Representatives in a manner that is contrary to Section 6.8(b). 
 (b) Sublicense Agreements.
Astellas shall, in each agreement under which it grants a sublicense pursuant to Section 8.3(a)(ii) under the license set forth in Section 8.1 (each, a “Sublicense Agreement”), require the Sublicensee to provide the
following to Medivation if this Agreement terminates, and to Astellas if only such Sublicense Agreement terminates: (i) the assignment and transfer of ownership and possession of, or a right of reference to, all Regulatory Materials and
Regulatory Approvals Controlled by such Sublicensee (which assignment or right of reference could also be provided directly to Astellas prior to any such termination),

 41 








 
but solely to the extent such assignment and transfer, or right of reference, would be required of Astellas under Section 14.5, and (ii) the assignment of, or a freely sublicensable
exclusive license to, all intellectual property Controlled by such Sublicensee that covers or embodies a Product or Collaboration Molecule or its respective use, manufacture, sale, or importation and was conceived or reduced to practice by or on
behalf of such Sublicensee during the exercise of its rights or fulfillment of its obligations pursuant to such Sublicense Agreement, but solely to the extent such assignment or exclusive license would be required of Astellas under
Section 14.5(a). Each Sublicense Agreement shall be subject to the applicable terms and conditions of this Agreement. For clarity, in the case of any subcontractor, this Section 8.3(b) shall not apply but Astellas shall comply with
Section 3.6, 6.8 or 7.9, as applicable. 
 8.4 Distributorships and Co-Promotion Rights. 

(a) Distributorships. Astellas shall have the right to appoint its Affiliates, and Astellas and its Affiliates shall have the right, in
their sole discretion, to appoint any other Persons, in any country(ies) in the Territory in accordance with Astellas’s typical practices for its proprietary products, to distribute, market, and sell Products (but not to [*] Products, except
that a grant of [*] in order to comply with Applicable Law or to the extent such grant is in accordance with Astellas’s typical practices for its proprietary products). If Astellas or its Affiliates appoints such a Person and such Person is not
an Affiliate of Astellas, that Person shall be a “Distributor” for purposes of this Agreement. Any agreement between a Distributor and Astellas or its Affiliates regarding a Product shall be on commercially reasonable and
arm’s-length terms. The term “[*]” in this Section 8.4(a) shall mean the right for the Distributor to [*] Products or components thereof supplied in [*] into [*]. 

(b) Promotion Rights. For the avoidance of doubt, subject to Section 6.8(b), Astellas and its Affiliates shall have the right to
co-promote the Products with any other Person(s) (in addition to Medivation), or to appoint one or more Third Parties to promote the Products without Astellas, (i) in all or any part of the Licensed Territory, or (ii) in the Shared
Territory to the extent permitted in the Joint Commercialization Plan or otherwise approved by the JCC or JSC. 
 8.5 UCLA
Agreement. The sublicenses granted by Medivation under the UCLA Technology are subject to the terms and conditions of the UCLA Agreement, including: (a) the reservation of rights in favor of the Regents, HHMI, and the U.S. government, as
set forth in Article 2 of the UCLA Agreement and (b) the requirement that any products embodying the licensed invention or produced through such invention’s use be manufactured in the U.S. to the extent required by 35 U.S.C. §§
201-212. Notwithstanding the foregoing, Medivation shall continue to be responsible for performing all obligations due to Regents and HHMI (and, if applicable, the U.S. government) that are set forth in the UCLA Agreement, subject to
Section 8.8(a). 
 8.6 Negative Covenant. Each Party covenants that it will not knowingly use or practice any of the other
Party’s intellectual property rights licensed to it under this Article 8 in a manner that would constitute infringement or misappropriation of such intellectual property rights except for the purposes expressly permitted in the applicable
license grant. 
 8.7 No Implied Licenses. Except as explicitly set forth in this Agreement, neither Party grants to the other Party
any license, express or implied, under its intellectual property rights. 
 8.8 Third Party Payments. 

(a) All [*] owed under [*] of the UCLA Agreement shall be (i) shared by the Parties as Joint Commercialization Costs to the extent
such [*] are with respect to [*] in [*] by [*] and (ii) borne solely by Astellas to the extent such [*] are with respect to [*] in [*] by [*]. Medivation shall be solely responsible for (A) [*] under the UCLA Agreement, including [*]
thereunder, and (B) unless otherwise agreed by Astellas in writing, any and all other payments due under any license agreement (other than the UCLA Agreement) entered into by Medivation and any Third Party, whether prior to, on or after the
Effective Date, except to the extent such payments constitute Third Party Payments hereunder (in which event each Party’s respective responsibility for such payments shall be as set forth in Section 8.8(b)). 

  
 [*] = Certain confidential
information contained in this document, marked by brackets, has been omitted and filed separately with the securities and exchange commission pursuant to rule 24b-2 of the securities exchange act of 1934, as amended. 


  
 42 








 (b) The Parties acknowledge that during the Term, the JSC may determine that planned
activities or Product features under this Agreement with respect to Collaboration Molecules or Products may require or benefit from a license under additional Third Party intellectual property other than the UCLA Technology. The Parties agree that
the payments to any Third Party in respect of any such license [*] or [*] shall be deemed a “Third Party Payment” and subject to this Section 8.8. Responsibility for Third Party Payments shall be as follows: 

(i) Medivation shall be responsible for all Third Party Payments with respect to licenses under [*] that [*] (in the [*] existing as of
the Effective Date) for the [*], including, for clarity, any [*] resulting from the exercise of such license with respect to any [*]. Medivation shall have sole responsibility and authority for negotiating the terms of any such license, subject to
the approval of Astellas, not to be unreasonably delayed or withheld. 
 (ii) Any Third Party Payments (other than Third Party
Payments covered in Section 8.8(b)(i)) that are (A) with respect to intellectual property that is [*] and [*] or by [*], and (B) payable with respect to the [*] or [*] the [*], will constitute Joint Development Costs or Joint
Commercialization Costs, as applicable, and be shared by the Parties pursuant to the profit sharing mechanism under this Agreement. 

(iii) Astellas shall be responsible for all Third Party Payments, other than those described in Sections 8.8(b)(i) and 8.8(b)(ii),
payable with respect to [*] of [*] or otherwise payable in connection with [*]. 
 (iv) If the Parties disagree as to whether
certain [*] as set forth in clause (i), such dispute (but no other dispute concerning whether a payment to a Third Party qualifies as a Third Party Payment under this Section 8.8(b) or any particular clause thereof) shall be resolved by a
Patent Expert pursuant to Section 15.10. In the event such Patent Expert concludes that the [*] as set forth in clause (i), payments to the Third Party in respect of a license to Exploit any [*] shall be allocated under clause (i) as if
such license had been approved by the JSC in accordance with the first paragraph of this Section 8.8(b). 
 8.9 Exclusivity.

 (a) Restriction. Each Party hereby covenants that, on a country-by-country basis, during [*], neither it nor its Affiliates
will, directly or indirectly, by itself or with a Third Party, market, promote or sell, or manufacture or distribute for commercial purposes, except as permitted in Section 8.9(b), any Restricted Product. 

(b) Notwithstanding Section 8.9(a), if Astellas or any of its Affiliates, either as a result of (x) the internal development
efforts of Astellas or any of its Affiliates or (y) an Acquisition, obtains an ownership, license or other rights to a Restricted Product (or, as a result of the Acquisition has as an Affiliate a Person that has an ownership, license or other
rights to a Restricted Product), then Astellas or its Affiliate shall promptly notify Medivation in writing (such notice, a “Restricted Product Notice”) no later than the Required Notice Date that Astellas is electing to: 

(i) divest itself of such Restricted Product in such country via a transaction in which Astellas no longer has an economic interest in
the future sales performance of the Restricted Product in such country and notify Medivation in writing of such divestiture, provided that such divestiture is completed within (A) [*] of the Required Notice Date in the case of [*], and
(B) prior to [*] of the [*], in the case of a Restricted Product that is not then being offered for commercial sale (the “Divestment Period”); 

(ii) [*]; 

(iii) terminate the Agreement [*] with respect to the Region in which such country is located; or 

  
 [*] = Certain confidential
information contained in this document, marked by brackets, has been omitted and filed separately with the securities and exchange commission pursuant to rule 24b-2 of the securities exchange act of 1934, as amended. 


  
 43 








 (iv) refrain, and cause its Affiliates to refrain, during [*], from directly or
indirectly, by itself or with a Third Party, from marketing, promoting or selling, or manufacturing or distributing for commercial sale in such country such Restricted Product, or, in the case of any such Restricted Product with respect to which
first commercial sale has occurred prior to the Required Notice Date, cease engaging in such prohibited activities with respect to such Restricted Product during [*] (in which event Astellas or its Affiliate, as applicable, shall have a period of
[*] days after the Required Notice Date to sell off existing inventory or work-in-progress with respect to such country). 
 As used herein,
“Required Notice Date” means first to occur of (A) the [*] day following the receipt of Regulatory Approval for the Restricted Product and (B) the first commercial sale of such Restricted Product; provided, however, that
the Required Notice Date for a Restricted Product resulting under Section 8.9(b)(y) shall in no event be prior to the [*] day following the consummation of the applicable Acquisition. 

For clarity, in any circumstance when Astellas complies with Section 8.9(b), Astellas shall not be in breach of Section 8.9(a). Moreover, in
circumstances where Astellas notifies Medivation that it intends to divest the Restricted Product pursuant to Section 8.9(b)(i), and fails despite reasonable efforts to complete such divestiture within the Divestment Period, Astellas shall not
be in breach of this Section 8.9, provided that Astellas pays to Medivation the amounts required pursuant to Section 8.9(b)(ii) with respect to any sales of Restricted Product occurring after the Divestment Period and during [*]. 

8.10 Additional Covenant Concerning Collaboration Molecules and Products. 

(a) During the Term, neither Party nor any of its Affiliates will Develop or Commercialize any Product or Collaboration Molecule except
pursuant to the Collaboration as set forth in this Agreement. 
 (b) During the Term, neither Party nor any of its Affiliates will
[*] using any [*] except pursuant to the Collaboration as set forth in this Agreement. 
 (c) Notwithstanding anything contained in
this Section 8.10 or any other term or condition of this Agreement to the contrary, nothing in this Agreement prohibits a Party or its Affiliates from conducting (i) [*], or (ii) [*]; provided in each case ((i) and (ii)) that such [*]
or [*] is designed or intended to further the research or development of, or support receipt of any regulatory approval for, [*]. 

ARTICLE 9 

FINANCIALS 

9.1 License Fee. No later than five (5) Business Days after the Effective Date, Astellas shall pay to Medivation a non-refundable,
non-creditable license fee of One Hundred Ten Million Dollars ($110,000,000). 
 9.2 Reconciliation/Reimbursement for the Shared
Territory Prior to Commercialization. Within [*] days after the end of each calendar quarter prior to the calendar quarter in which the First Commercial Sale of a Product occurs in the Shared Territory, Medivation and AUS shall submit to a
finance officer designated by Medivation and a finance officer designated by AUS (the “Finance Officers”) a report setting forth the Joint Development Costs, Joint Medical Affairs Costs and Joint Commercialization Costs it incurred
in such calendar quarter with respect to each Product. Each such report shall specify in reasonable detail all such costs, and, if requested by Medivation or AUS, any invoices or other supporting documentation for any payments to a Third Party that
individually exceed [*] or with respect to which documentation is otherwise reasonably requested shall be promptly provided. Within [*] Business Days after receipt of such reports, the Finance Officers shall confer and agree in writing on whether a
reconciliation payment is due from Medivation to AUS or AUS to Medivation, and if so, the amount of such reconciliation payment, so that Medivation and AUS share Joint Development Costs, Joint Medical Affairs Costs and Joint Commercialization Costs
in accordance with this Agreement. Medivation or AUS, as applicable, if required to pay such reconciliation payment, shall submit such payment to AUS or Medivation, respectively, as applicable, within [*] Business Days after the end of such [*]
Business Day conferral period; provided, however, that in the event of any disagreement with respect to the calculation of such reconciliation payment, any undisputed portion of such reconciliation payment shall be paid in accordance with the
foregoing timetable and the remaining, disputed portion shall be paid within [*] Business Days after the date on which

information contained in this document, marked by brackets, has been omitted and filed separately with the securities and exchange commission pursuant to rule 24b-2 of the securities exchange act of 1934, as amended.

Medivation and AUS, using good faith efforts, resolve the dispute. In addition, following the Effective Date, each Party shall consider in good faith other reasonable procedures proposed by the
other Party for sharing financial information in order to permit each Party to close its books periodically in a timely manner. For the avoidance of doubt, no cost or expense shall be counted more than once in calculating Joint Development Costs,
Joint Medical Affairs Costs and Joint Commercialization Costs, even if such costs or expense falls into more than one of the cost categories that comprise Joint Development Costs, Joint Medical Affairs Costs and Joint Commercialization Costs. 

9.3 Profit Sharing in the Shared Territory Following Commercialization. The terms and conditions of this Section 9.3 shall govern
the rights and obligations of Medivation and AUS with respect to Operating Profits (or Losses) relating to each Product in the Shared Territory. For clarity, Medivation shall have no right to share Operating Profits, and no obligation to bear any
Operating Losses, with respect to any Product in the Licensed Territory, and Medivation shall instead be entitled to receive from API royalties pursuant to Section 9.6. 

(a) Share of Operating Profits and Operating Losses. For so long as Product is being sold in the Shared Territory, Medivation and AUS
shall share all Operating Profits and all Operating Losses (as applicable) for each Product in the Shared Territory on the basis of fifty percent (50%) to AUS and fifty percent (50%) to Medivation. 

(b) Calculation and Payment. Within [*] after the end of each calendar quarter beginning with the calendar quarter in which the First
Commercial Sale of a Product occurs in the Shared Territory, AUS shall report to the Finance Officers its Net Sales, and Medivation and AUS shall each report to the Finance Officers its Joint Development Costs, Joint Medical Affairs Costs and Joint
Commercialization Costs incurred by it in such calendar quarter for each Product. Each such report shall specify in reasonable detail all deductions allowed in the calculation of such Net Sales and all expenses included in Joint Development Costs,
Joint Medical Affairs Costs, and Joint Commercialization Costs, and, if requested by Medivation or AUS, any invoices or other supporting documentation for any payments to a Third Party that individually exceed [*] or with respect to which
documentation is otherwise reasonably requested shall be promptly provided. Within [*] Business Days after receipt of such reports, the Finance Officers shall confer and agree upon in writing a consolidated financial statement setting forth the
Operating Profit or Operating Loss for such calendar quarter for such Product in the Shared Territory and calculating each Party’s share of such Operating Profit or Operating Loss. Within [*] Business Days after such [*] Business Day conferral
period, Medivation or AUS, as applicable, shall make a payment to AUS or Medivation respectively, as applicable, so that each of Medivation and AUS has been compensated for its respective share of such Operating Profits, or has borne its respective
share of such Operating Loss, as applicable, after giving effect to the Net Sales invoiced by AUS and the Joint Development Costs, Joint Medical Affairs Costs, and Joint Commercialization Costs incurred by Medivation and AUS with respect to such
Product in such calendar quarter; provided, however, that in the event of any disagreement with respect to the calculation of such payment, any undisputed portion of such payment shall be paid in accordance with the foregoing timetable and the
remaining, disputed portion shall be paid within [*] Business Days after the date on which Medivation and AUS, using good faith efforts, resolve the dispute. In addition, following the Effective Date, each Party shall consider in good faith other
reasonable procedures proposed by the other Party for sharing financial information in order to permit each Party to close its books periodically in a timely manner. For the avoidance of doubt, no cost or expense shall be counted more than once in
calculating Joint Development Costs, Joint Medical Affairs Costs and Joint Commercialization Costs, even if such costs or expense falls into more than one of the cost categories that comprise Joint Development Costs, Joint Medical Affairs Costs and
Joint Commercialization Costs. 
 (c) Consistency with Accounting Treatment. All calculations of Joint Development Costs, Joint
Medical Affairs Costs, Joint Commercialization Costs, Operating Profit and Operating Loss hereunder shall be made in accordance with GAAP, including the provisions thereof regarding expense recognition, as applied by Medivation and AUS consistently
with their application in their respective external financial reporting.

(c) Backup Products. For any Backup Product that first achieves one or more of the above described milestone events, the milestone
payment(s) listed above shall be [*], and such milestone payment(s) shall not be payable if any other Product later achieves such milestone(s). 

(d) Milestone Events for [*] Indication. In the event that a patient is dosed in a Phase 3 Clinical Trial that is designed specifically
to support receipt of Regulatory Approval for [*] and the [*], upon achievement of such milestone event the total milestone payment due will equal [*], and thereafter no milestone payment shall be payable for the first dosing of a patient in a [*]
for [*] Indication or the [*] Indication. In the event that any of the other above milestone events is achieved for the [*] Indication, then upon achievement of such milestone event the total milestone payment due will equal [*] (provided that the
applicable milestone payment for the [*] Indication has not previously been paid), and thereafter the applicable milestone payment for the [*] Indication shall not be payable. By way of example, upon [*] in the [*] for the [*] Indication, the total
milestone payment due shall be [*], provided that the [*] milestone payment for achieving such milestone event with respect to the [*] Indication had not been previously paid (and thereafter no milestone payment will be payable even upon the
subsequent [*] in the [*] for the [*] Indication). 
 (e) Notice; Payment. Astellas shall notify and pay to Medivation the amounts
set forth in this Section 9.4 within [*] days after the achievement of the applicable milestone event by Astellas, its Affiliate or a Sublicensee (or, if applicable, by Medivation). Each such payment shall be made by wire transfer of

9.6 Royalties. 
 (a)
Licensed Territory. Astellas shall pay to Medivation non-refundable, non-creditable royalties on the amount of aggregate Net Sales of each Product in the Licensed Territory in each calendar year, as calculated by multiplying the applicable

information contained in this document, marked by brackets, has been omitted and filed separately with the securities and exchange commission pursuant to rule 24b-2 of the securities exchange act of 1934, as amended. 


  
 47 








 (b) Royalty Term. Astellas’s obligation to pay royalties under this Section 9.6
with respect to a particular Product in each country in the Licensed Territory will commence upon the First Commercial Sale of such Product in such country and will end on the earliest date on which all of the following are true: (i) there is
no Valid Claim that would be infringed, absent a license, by the manufacture, use or sale of such Product in such country, (ii) there is no Regulatory Exclusivity in such country with respect to such Product, and (iii) the first commercial
sale of a Generic Product has occurred in such country (such period, the “Royalty Term”). 
 (c) Backup Products.
For any Backup Product, the royalty rates provided in this Section 9.6 shall be [*]. 
 (d) Royalty Payments and Reports. All
amounts payable to Medivation pursuant to this Section 9.6 shall be paid in U.S. dollars within [*] days after the end of each calendar quarter with respect to Net Sales in such calendar quarter. Each payment of royalties due to Medivation
shall be accompanied by a statement, on a country-by-country basis, of the amount of gross sales of Products in the Licensed Territory during the applicable calendar quarter, a calculation of Net Sales in the Licensed Territory showing with
reasonable specificity the aggregate deductions from gross sales provided for in the definition of Net Sales during such calendar quarter, and a calculation of the amount of royalty payment due on such sales for such calendar quarter. 

(e) Following Royalty Term. Upon expiration of the Royalty Term with respect to a Product in a country, Astellas’s license with
respect to the Product in such country shall become non-exclusive, fully paid-up, perpetual, and irrevocable; no royalties or milestone payments shall be due thereafter with respect to Net Sales of the Product in such country; and such Net Sales
shall be excluded from the calculation of sales milestones and royalty tiers under this Article 9. Astellas and its Affiliates and Sublicensees shall have the right to continue Exploiting the Product and using all Medivation Know-How and
Medivation’s interests in Joint Inventions in connection therewith on a non-exclusive basis in such country. 
 9.7 Other Amounts
Payable. Within [*] days after the end of each calendar quarter, each Party shall invoice the other Party for any amounts owed by the other Party under this Agreement that are not otherwise accounted for in this Article 9, including payments in
respect of recall expenses pursuant to Section 4.2, Third Party Payments that are the responsibility of one Party or the other pursuant to Section 8.8(b)(i) or 8.8(b)(iii), and payments made on account of expenses and recoveries pursuant
to Section 10.4(d). The invoicing Party shall have the right to offset part or all of such invoiced amount against payments owed to the other Party by the invoicing Party pursuant to this Article 9 (including payments in respect of milestones,
royalties, or Operating Profit or Loss). The owing Party shall pay any undisputed amounts that have not been so offset within [*] days of receipt of the invoice, and any disputed amounts owed by a Party shall be paid (or offset) within [*] days of
resolution of the dispute. 
 9.8 Taxes.  

(a) Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising
directly or indirectly from the collaborative efforts of the Parties under this Agreement. 
 (b) Tax Cooperation. The Parties agree
to cooperate with one another and use reasonable efforts to avoid or reduce tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Astellas to Medivation under this Agreement. Without limiting
the generality of the foregoing, Medivation shall provide Astellas any tax forms and other information that may be reasonably necessary in order for Astellas to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral
income tax treaty. Medivation shall provide any such tax forms to Astellas at least [*] days prior to the due date for any payment for which Medivation desires that Astellas apply a reduced withholding rate. Each Party shall provide the other with
reasonable assistance to enable the recovery, as permitted by Applicable Law, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing
such withholding tax or value added tax. 
 (c) Payment of Tax. To the extent Astellas is required by Applicable Law to deduct and
withhold taxes on any payment to Medivation, Astellas shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to Medivation an official tax certificate or other evidence of such withholding
sufficient to enable Medivation to claim such payment of taxes. 

  
 [*] = Certain confidential
information contained in this document, marked by brackets, has been omitted and filed separately with the securities and exchange commission pursuant to rule 24b-2 of the securities exchange act of 1934, as amended. 


  
 48 








 (d) Treatment of Certain Withholding Taxes. If Astellas is [*] to deduct and withhold
taxes on any payment to Medivation and such withholding obligation arises either (i) with respect to [*] (a “Specified [*]”) or (ii) as a result of any action by Astellas that has the effect of modifying the tax treatment
of the Parties hereto (including any assignment or sublicense, or any failure on the part of Astellas to comply with Applicable Law or filing or record retention requirements) (an “Astellas Withholding Tax Action”), then the sum
payable by Astellas (in respect of which such deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that Medivation actually receives, as appropriate, a sum equal to the Specified Payment or the sum
that it would have received had no such Astellas Withholding Tax Action occurred; provided, however, that no such increase shall apply to the extent such increase would have resulted (x) from a change in Applicable Law increasing the applicable
withholding tax rate, which change occurs after the Effective Date, (y) in circumstances where actions or inactions of Medivation or any of its Affiliates cause a change in the applicable withholding tax rate, for example, the failure of
Medivation to timely provide to Astellas the appropriate treaty forms and the certificate of residence necessary for Astellas to withhold at a more favorable rate or (z) from the failure of Medivation to meet a limitation of benefits provision
of the US/Japan Tax Treaty. 
 9.9 Blocked Currency. In each country where the local currency is blocked and cannot be removed from
the country, royalties accrued on Net Sales in that country shall be paid to Medivation in the equivalent amount in U.S. dollars. 
 9.10
Foreign Exchange. The rate of exchange to be used in computing the amount of currency equivalent in U.S. dollars of Net Sales invoiced and Joint Development Costs, Joint Commercialization Costs and Joint Medical Affairs Costs incurred in other
currencies shall be made at the average T.T.M. rate published by the Bank of Tokyo Mitsubishi UFJ, Ltd. in Japan for the first, middle and last Business Day of the applicable reporting period for the payment due. 

9.11 Late Payments. If a Party does not receive payment of any sum due to it on or before the due date therefor, simple interest shall
thereafter accrue on the sum due to such Party from the due date until the date of payment at a per-annum rate of [*] or the maximum rate allowable by Applicable Law, whichever is less. 

9.12 Financial Records; Audits. Each Party shall maintain complete and accurate records in sufficient detail to permit the other Party

generated (as applicable) by such Party, achievement of sales milestones, royalty payments and other compensation or reimbursement payable under this Agreement. Upon reasonable prior notice, such records shall be open during regular business hours
for a period of [*] years from the creation of individual records for records pertaining to activities in [*], and for a period of [*] years from the creation of individual records for all other records, in each case, for examination at the auditing

Party the accuracy of the financial statements or reports or sales milestone notices furnished by the audited Party pursuant to this Agreement or of any payments made, or required to be made, by or to the audited Party to the other pursuant to this
Agreement. Any such auditor shall not disclose the audited Party’s confidential information to the auditing Party, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by the audited Party
or the amount of payments due by the audited Party under this Agreement. Any amounts shown to be owed but unpaid, or overpaid and in need of reimbursement, shall be paid or refunded (as the case may be) within [*] days after the accountant’s
report, plus interest (as set forth in Section 9.11) from the original due date (unless (x) challenged in good faith by the audited Party, in which case any undisputed portion shall be paid in accordance with the foregoing timetable, any
dispute with respect to such challenge shall be resolved in accordance with Article 15, any remaining disputed portion shall be paid within [*] days after resolution of the dispute, and interest shall not accrue with respect to the disputed portion

by, the audited Party that resulted from a discrepancy in a report that the audited Party provided to the other Party during the applicable audit period, which underpayment or overpayment was more than [*] of the amount set forth in such report, in
which case the audited Party shall bear the full cost of such audit. 
 9.13 Manner and Place of Payment. All payments owed under
this Agreement shall be made by wire transfer in immediately available funds to a bank and account designated in writing by Medivation or Astellas (as applicable), unless otherwise specified in writing by such Party.

written notice to Medivation requesting that Medivation file such patent application in such jurisdiction. If Astellas provides such written notice to Medivation, Medivation shall either
(i) file, prosecute and maintain such patent application and maintain any patent issuing thereon in such jurisdiction, or (ii) notify Astellas that Medivation does not desire to file, prosecute or maintain such patent application and, upon
Astellas’s request, Medivation shall assign all of its rights, title and interest in such Medivation Patent to Astellas at no cost to Astellas, and such Patent shall no longer be deemed a Medivation Patent. Astellas’s rights under this
Section 10.3(a) with respect to any Medivation Patent licensed to Medivation by a Third Party after the Effective Date shall be subject to the rights of such Third Party to file, prosecute, and/or maintain such Medivation Patent. Medivation
shall be responsible for all costs incurred by it in the course of preparing, filing, prosecuting and maintaining the Medivation Patents, without reimbursement by Astellas. If Astellas assumes responsibility for any Medivation Patents pursuant to
clause (ii) above, then all costs incurred by Astellas in the course of course of preparing, filing, prosecuting and maintaining such Medivation Patents shall be borne by Astellas, without reimbursement by Medivation. 

(b) UCLA Technology. [*]. Medivation shall provide Astellas reasonable opportunity to review and comment on any documents relating to
such filing and prosecution efforts that the Regents provide to Medivation or that Medivation intends to send to the Regents. Medivation shall not [*] to [*] any UCLA Technology anywhere in the Territory unless Medivation obtains for Astellas, at
least [*] days before any [*] for [*] to [*], the [*] to [*] such UCLA Technology in the Territory on behalf of the Regents. Medivation shall be responsible for all costs incurred by it or the Regents in the course of the preparing, filing,
prosecuting and maintaining the UCLA Technology by the Regents, without reimbursement by Astellas. If Astellas assumes responsibility for any UCLA Technology [*], then all costs incurred by Astellas in the course of course of preparing, filing,
prosecuting and maintaining such UCLA Technology shall be borne by Astellas, without reimbursement by Medivation.  
 (c) Astellas
Patents. Except as otherwise provided in this Section 10.3(c), Astellas shall have the sole right and authority to prepare, file, prosecute (including any oppositions, interferences, reissue proceedings, reexaminations and other post-grant
proceedings) and maintain the Astellas Patents in any jurisdiction in the Territory. Astellas shall provide Medivation reasonable opportunity to review and comment on such prosecution efforts regarding such Astellas Patents in the Territory.
Astellas shall provide Medivation with a copy of material communications from any patent authority in the Territory regarding such Astellas Patents, and shall provide drafts of any material filings or responses to be made to such patent authorities
a reasonable amount of time in advance of submitting such filings or responses. Astellas shall be responsible for all costs incurred by it in the course of preparing, filing, prosecuting and maintaining the Astellas Patents, without reimbursement by
Medivation. 
 (d) Joint Patents. With respect to any potentially patentable Joint Invention, Astellas shall have the first right,
but not the obligation, to prepare patent applications based on such Joint Invention, to file and prosecute (including the defense of any oppositions, interferences, reissue proceedings, reexaminations and other post-grant proceedings originating in
a patent office) and maintain such patent applications, and any Patents issuing therefrom (any such patent application and Patents, a “Joint Patent”), in any jurisdictions throughout the Territory. If Astellas determines in its sole
discretion to abandon, cease prosecution or otherwise not file or maintain any Joint Patent anywhere in the Territory, then Astellas shall provide Medivation written notice of such determination at least [*] days before any deadline for taking
action to avoid abandonment (or other loss of rights) and shall provide Medivation with the opportunity to prepare, file, prosecute and maintain such Joint Patent. The Party that is responsible for preparing, filing, prosecuting, and maintaining a
particular Joint Patent (the “Prosecuting Party”) shall provide the other Party reasonable opportunity to review and comment on such prosecution efforts regarding such Joint Patent, and such other Party shall provide the Prosecuting
Party reasonable assistance in such efforts. The Prosecuting Party shall provide the other Party with a copy of all material communications from any patent authority in the applicable jurisdictions regarding the Joint Patent being prosecuted by such
Party, and shall provide drafts of any material filings or responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses. In particular, each Party agrees to provide the other Party
with all information necessary or desirable to enable the other Party to comply with the duty of candor/duty of disclosure requirements of any patent authority. Either Party may determine that it is no longer interested in supporting the continued
prosecution or maintenance of a particular Joint Patent in a country or jurisdiction, in which case: (i) the disclaiming Party shall, if requested in writing by the other Party, assign its ownership interest in such Joint Patent in


  
 [*] = Certain confidential

 51 








 
such country or jurisdiction to the other Party for no additional consideration; and (ii) if such assignment is effected, any such Joint Patent would thereafter be deemed a Medivation Patent
in the case of assignment to Medivation, or an Astellas Patent in the case of assignment to Astellas; provided, however, that the disclaiming party and any Affiliate thereof would have an immunity from suit under such Medivation Patent or Astellas
Patent, as the case may be, in the applicable country or jurisdiction. In addition, any Joint Patent that becomes a Medivation Patent pursuant to the preceding sentence shall be excluded from the license granted to API in Section 8.1 but claims
therein shall continue to be eligible to be included in the definition of a Valid Claim for purposes of Section 9.6 in accordance with the terms and conditions of such definition. Each Party shall bear its own internal costs in respect of the
prosecution of Joint Patents. Out-of-pocket costs incurred in respect of the prosecution and maintenance of Joint Patents shall be borne (i) [*] by Astellas and [*] by Medivation in the Shared Territory and (ii) [*] by Astellas and [*] by
Medivation in the Licensed Territory. In the event a Party elects to disclaim its interest in a Joint Patent, the costs incurred with respect to such Patent after the date of such disclaimer shall thereafter be borne exclusively by the other Party,
without reimbursement or credit. 
 (e) Cooperation in Prosecution. Each Party shall provide the other Party all reasonable notice,
assistance and cooperation in the Patent prosecution efforts provided above in this Section 10.3, including providing any necessary powers of attorney and executing any other required documents or instruments for such prosecution. 

(f) Patent Term Extensions. Each Party shall consult with the other Party before applying for or obtaining any patent term extension or
related extension of rights, including supplementary protection certificates and similar rights for any Collaboration Patents anywhere in the Territory. Neither Party shall proceed with such an extension except as follows. If the Parties disagree on
the appropriate strategy with respect to an extension, the disagreement shall be resolved by the JSC. If the JSC is unable to reach consensus on the strategy, Astellas shall have the final say with respect to the matter; provided that Astellas
considers, reasonably and in good faith all input received from Medivation, and provided further that Astellas exercises such final say in a manner reasonably believed to be in the best interests of the Development and Commercialization of Products.
Each Party shall provide reasonable assistance to the other Party (and Medivation shall use commercially reasonable efforts to cause the Regents to provide reasonable assistance to Astellas) in connection with obtaining any such extensions for the
Collaboration Patents consistent with such strategy. To the extent reasonably and legally required in order to obtain any such extension in a particular country, each Party shall make available to the other a copy of the necessary documentation to
enable such other Party to use the same for the purpose of obtaining the extension in such country. 
 (g) Orange Book Listings.
Astellas shall have the sole right to make any filing with respect to any Collaboration Patent in connection with the FDA’s Orange Book, under the national implementations of Article 10.1(a)(iii) of Directive 2001/EC/83 or other
international equivalents. Astellas shall consult with Medivation regarding the strategy therefor. If the Parties disagree on the appropriate strategy with respect to such a filing, the disagreement shall be resolved by the JSC. If the JSC is unable
to reach consensus on the strategy, Astellas shall have the final say with respect to the matter; provided that Astellas considers, reasonably and in good faith all input received from Medivation, and provided further that Astellas exercises such
final say in a manner reasonably believed to be in the best interests of the Development and Commercialization of Products. Each Party shall provide reasonable assistance to the other Party in connection with any such filing. 

10.4 Infringement of Collaboration Patents by Third Parties. 

(a) Notification. If either Party becomes aware of any infringement, threatened infringement, or alleged infringement of any
Collaboration Patent (in each case, a “Third Party Infringement”) or either Party receives any notice of any certification filed under the US “Drug Price Competition and Patent Term Restoration Act” of 1984 (21 United
States Code §355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV)), as amended or supplemented (or any successor law) claiming that any Collaboration Patent is invalid or unenforceable or claiming that any Collaboration Patent will not be infringed by the
manufacture, use, marketing, or sale of a product for which an application under such act is filed ([*] collectively with any Third Party Infringement, a “Product Infringement”), then each Party shall promptly (and in the case of an
[*], no later than three (3) Business Days following receipt of such notice) notify the other Party in writing thereof, and, in the case of a Third Party Infringement, shall provide evidence in such Party’s possession demonstrating such
threatened, alleged or actual infringement.

 (b) Enforcement Rights.  

(i) Medivation Patents and Joint Patents. Subject to Section 10.4(e) and the remainder of this Section 10.4(b)(i), Astellas
shall have the first right, but not the obligation, to bring an appropriate suit or other action against any person or entity allegedly engaged in any Product Infringement of the Medivation Patents or the Joint Patents in the Territory (and to
defend any related counterclaim), at Astellas’s expense. Astellas shall have a period of [*] days (or, in the case of [*], [*] days) after its receipt or delivery of notice and evidence pursuant to Section 10.4(a), to elect to so enforce
such Medivation Patent or Joint Patent in the Territory (or to settle or otherwise secure the abatement of such Product Infringement). In the event Astellas does not so elect (or settle or otherwise secure the abatement of such Product
Infringement), it shall so notify Medivation in writing, and Medivation shall have the right to commence a suit or take action to enforce the applicable Medivation Patents or Joint Patents with respect to such Product Infringement in the Licensed
Territory (and to defend any related counterclaim), at Medivation’s expense. Each Party shall provide to the Party enforcing any such rights under this Section 10.4(b)(i) reasonable assistance in such enforcement, at such enforcing
Party’s request and expense, including joining such action as a party plaintiff if required to perfect or maintain jurisdiction to pursue such action. The enforcing Party shall keep the other Party regularly informed of the status and progress
of such enforcement efforts, and shall reasonably consider the other Party’s comments on any such efforts. 
 (ii) UCLA Technology.
Subject to Section 10.4(e) and the remainder of this Section 10.4(b)(ii), Astellas shall have the first right, but not the obligation, to bring an appropriate suit or other action against any person or entity allegedly engaged in any
Product Infringement of the UCLA Technology in the Territory (and to defend any related counterclaim), at Astellas’s expense. Astellas shall have a period of [*] days (or, in the case of [*], to the extent permitted under the UCLA Agreement, as
amended, [*] days) after its receipt or delivery of notice and evidence pursuant to Section 10.4(a), to elect to so enforce such UCLA Technology in the Territory (or to settle or otherwise secure the abatement of such Product Infringement). In
the event Astellas does not so elect (or settle or otherwise secure the abatement of such Product Infringement), it shall so notify Medivation in writing, and, as between the Parties, Medivation shall have the right to commence a suit or take action
to enforce the applicable UCLA Technology with respect to such Product Infringement in the Licensed Territory (and to defend any related counterclaim), at Medivation’s expense. Each Party shall provide to the Party enforcing any such rights
under this Section 10.4(b)(ii) reasonable assistance in such enforcement (such assistance shall include, if Astellas is the Party enforcing the rights, Medivation [*] to [*] to [*] to [*] as [*] if required to [*] to [*]), at such enforcing
Party’s request and expense, including joining such action as a party plaintiff if required to perfect or maintain jurisdiction to pursue such action. The enforcing Party shall keep the other Party regularly informed of the status and progress
of such enforcement efforts, and shall reasonably consider the other Party’s comments on any such efforts. Astellas acknowledges and agrees that, under the UCLA Agreement, Medivation is not permitted to initiate any such suit until [*] days
following the date that the applicable Infringement Notice (as defined in the UCLA Agreement) takes effect (or within the applicable timeframe required by law if the Infringement Notice is predicated on the receipt of a notice of certification sent
or filed pursuant to the U.S. “Drug Price Competition and Patent Term Restoration Act” of 1984 or any equivalent or similar notice or certification in any foreign jurisdiction, that the applicable UCLA Patent is invalid or unenforceable or
claiming that the UCLA Patent will not be infringed by the Manufacture, use, marketing or sale of a product for which an application under the act is filed), and Astellas’s right to initiate any such suit shall be subject to the
identical limitation. Astellas acknowledges and agrees that the Regents retains a secondary right to institute suit for patent infringement with respect to a Product Infringement, if, within [*] days following the date that the applicable
Infringement Notice (as defined in the UCLA Agreement) takes effect, infringing activity of potential commercial significance by the infringer has not been abated and a suit has not been brought against the infringer, as set forth in more detail in
the UCLA Agreement. In the event that the Regents institutes such a suit, Astellas shall have no further rights under this Section 10.4(b)(ii) with respect to the alleged infringement.

 53 








 (iii) Astellas Patents. Astellas shall have the sole right, but not the obligation, to
bring an appropriate suit or other action against any person or entity allegedly engaged in any Product Infringement of the Astellas Patents. Medivation shall provide reasonable assistance to Astellas in such enforcement, at Astellas’s request
and expense. Astellas shall keep Medivation regularly informed of the status and progress of such enforcement efforts. 
 (c) Settlement.
Without the prior written consent of the other Party, neither Party shall settle any claim, suit or action that it brought under this Section 10.4 involving Collaboration Patents in any manner that would negatively impact such intellectual
property or that would limit or restrict the ability of either Party to sell Products anywhere in the Territory. 
 (d) Expenses and
Recoveries. A Party bringing a claim, suit or action under Section 10.4(b)(i), 10.4(b)(ii), or 10.4(b)(iii) against any person or entity engaged in Product Infringement of the Collaboration Patents shall be solely responsible for any
expenses incurred by such Party as a result of such claim, suit or action. If such Party recovers monetary damages from such Third Party in such suit or action, such recovery shall be allocated first to the reimbursement of any expenses incurred by
the Parties in such litigation (including, for this purpose, a reasonable allocation of expenses of internal counsel) and, solely to the extent required by the UCLA Agreement, to reimburse the Regents for costs and expenses incurred by the Regents,
and any remaining amount (after payment of any share thereof owed to the Regents under the UCLA Agreement) shall be distributed as follows: (1) to the extent the recovery related to infringing activities in the Shared Territory, [*] to Astellas
and [*] to Medivation, and (2) to the extent the recovery related to infringing activities in the Licensed Territory, [*] to Astellas and [*] to Medivation. 

(e) Patents Licensed from Third Parties. Each Party’s rights under this Section 10.4 with respect to any Collaboration Patent
licensed to the other Party by a Third Party shall be subject to the rights of such Third Party to enforce such Collaboration Patent and/or defend against any claims that such Collaboration Patent is invalid or unenforceable. 

10.5 Defense of Collaboration Patents. Except as set forth in Section 10.3(a), (b) or (c), to the extent any Party receives
notice by counterclaim, or otherwise, alleging the invalidity or unenforceability of any Collaboration Patent, it shall bring such fact to the attention of the other Party, including all relevant information related to such claim. The Parties,
through the JSC, shall discuss such claim. Where such allegation is made in an opposition, reexamination, interference or other patent office proceeding, the provisions of Section 10.3 shall apply. Where such allegation is made in a
counterclaim to a suit or other action brought under Section 10.4, the provisions of Section 10.4 shall apply. In all other cases, (a) where such allegation relates to a Collaboration Patent within the Shared Territory, the JSC
shall determine which Party is most appropriate to take the lead in defending such allegation and all reasonable costs incurred in connection with such defense shall be included as Joint Commercialization Costs, and (b) where such action
relates to a Collaboration Patent within the Licensed Territory, Astellas shall have the first right to defend such action, at Astellas’s expense, and Medivation will cooperate with Astellas, at Astellas’s expense in such defense. In the
event Astellas does not so elect to defend an action with respect to any Medivation Patent, Joint Patent, or UCLA Patent under this Section 10.5, it shall so notify Medivation in writing, and Medivation shall have the right to so defend such
action in the Licensed Territory, at Medivation’s expense (but, for clarity, Medivation shall have no such right with respect to any Astellas Patent). Each Party shall provide to the Party defending any such rights under this Section 10.5
in the Licensed Territory all reasonable assistance in such enforcement, at such defending Party’s request and expense. The defending Party shall keep the other Party regularly informed of the status and progress of such efforts, and shall
reasonably consider the other Party’s comments on any such efforts. 
 10.6 Defense of Infringement Actions. During the
Term, each Party shall bring to the attention of the other Party all information regarding potential infringement or any claim of infringement of Third Party intellectual property rights in connection with the development, manufacture, production,
use, importation, offer for sale, or sale of Products in the Territory. The Parties shall discuss such information and decide how to handle such matter. Subject to Article 12, each Party shall be solely responsible for defending any action, suit, or
other proceeding brought against it alleging infringement of Third Party intellectual property rights in connection with its activities under this Agreement. This Section 10.6 shall not be interpreted as placing on either Party a duty of
inquiry regarding Third Party intellectual property rights.

 10.7 Patent Marking. Astellas shall, and shall require its Affiliates and Sublicensees, to
mark Products sold by it hereunder (in a reasonable manner consistent with industry custom and practice) with appropriate patent numbers or indicia to the extent permitted by Applicable Law, in those countries in which such markings or such notices
impact recoveries of damages or equitable remedies available with respect to infringements of patents. 
 10.8 Personnel Obligations.
Prior to beginning work under this Agreement relating to any research, Development or Commercialization of a Collaboration Molecule or a Product, each employee, agent or independent contractor of Astellas or Medivation or of either Party’s
respective Affiliates shall be bound by non-disclosure and invention assignment obligations which are consistent with the obligations of Astellas or Medivation, as appropriate, in this Article 10, to the extent permitted by Applicable Law, including
without limitation: (a) promptly reporting any invention, discovery, process or other intellectual property right; (b) assigning to Astellas or Medivation, as appropriate, all of his or her right, title and interest in and to any
invention, discovery, process or other intellectual property right; (c) in the case of employees, agents, or independent contractors working in the United States, taking actions reasonably necessary to secure patent protection;
(d) performing all acts and signing, executing, acknowledging and delivering any and all documents required for effecting the obligations and purposes of this Agreement; and (e) abiding by the obligations of confidentiality and non-use set
forth in Article 13. It is understood and agreed that such non-disclosure and invention assignment agreement need not reference or be specific to this Agreement. 

10.9 Trademarks. Astellas shall be responsible for the selection, registration, maintenance and defense of all trademarks for use in
connection with the sale or marketing of Products in the Field in the Territory (the “Marks”). The fees and expenses incurred in connection therewith for Marks applicable to Product in the Licensed Territory shall be the
responsibility of Astellas, and the Trademark Costs shall be deemed Joint Commercialization Costs. All uses of the Marks shall be reviewed by the JCC and shall comply with Applicable Law (including, without limitation, those laws and regulations
particularly applying to the proper use and designation of trademarks in the applicable countries). Neither Party shall, without the other Party’s prior written consent, use any trademarks or house marks of the other Party (including the other
Party’s corporate name), or marks confusingly similar thereto, in connection with such Party’s marketing or promotion of Products under this Agreement, except as may be expressly authorized in connection with activities under
Section 6.9 or the Co-Promotion Agreement and except to the extent required to comply with Applicable Law. Astellas shall own all Marks with respect to the Products. 

10.10 Confirmatory Patent Licenses. Medivation shall, if so requested by Astellas, promptly enter into confirmatory license agreements,
in a form consistent with the terms of this Agreement and reasonably acceptable to the Parties, for purposes of recording the licenses granted under this Agreement with such patent offices in the Territory as Astellas considers appropriate. Astellas
shall bear any filing costs and any costs of outside counsel or experts required with respect to such recordations. 
 10.11 Designation
of Astellas Patents. If Astellas decides that it would like to incorporate into a Product any invention claimed or covered by one or more Patents Controlled by Astellas or that it would otherwise like to use such an invention in the Development,
Manufacture, or Commercialization of Products, Astellas shall provide Medivation with written notice thereof, including a description of such invention and an identification of the applicable Patent(s). In addition, Medivation shall have the right
to propose to Astellas that an invention claimed or covered by one or more Patents Controlled by Astellas be incorporated or used in such manner. In any event, if and only if the Parties mutually agree to incorporate an invention claimed or covered
by one or more Patents Controlled by Astellas into a Product or to use such invention in the Development, Manufacture, or Commercialization of Products, each such Patent shall thereafter be deemed to be an Astellas Patent. Astellas shall use
commercially reasonable efforts to refrain, and to cause its Affiliates to refrain, from the use of any invention in the Development, Manufacture, or Commercialization of Product or the incorporation of any such invention into a Product, to the
extent that Astellas knows that such invention would, at the time of such use or incorporation, be covered by a Patent Controlled by Astellas (other than an Astellas Patent), and Astellas shall not knowingly and intentionally

advocate for such use or incorporation, unless Astellas first advises Medivation of such Patent and offers to include it as an Astellas Patent pursuant to this Section 10.11. If Astellas
breaches its obligations pursuant to the immediately preceding sentence with respect to any invention or Patent Controlled by Astellas, then Astellas may cure such breach by thereafter advising Medivation of the Patent and offering to include it as
an Astellas Patent pursuant to this Section 10.11, and such obligation shall be Medivation’s sole remedy with respect to such breach.

not enter into any agreement that would prevent it from granting the rights or exclusivity granted or intended to be granted to the other Party under this Agreement or performing its obligations under this Agreement. 

(d) No Debarment. Such Party is not debarred, has not been convicted, and is not subject to debarment or conviction pursuant to
Section 306 of the FD&C Act. In the course of the Development of Products, such Party has not used prior to the Effective Date and shall not use, during the Term, any employee, agent or independent contractor who has been debarred by any

reasonable attorneys’ fees and costs of litigation incurred by such Astellas Indemnitees (collectively, “Astellas Damages”), all to the extent resulting from claims, suits, proceedings or causes of action brought by or on
behalf of such Third Party (“Astellas Claims”) against such Astellas Indemnitee that arise from or are based on: 

(a) (i) a breach of any of Medivation’s representations, warranties, and obligations under this Agreement; (ii) the willful
misconduct or grossly negligent acts of Medivation, its Affiliates, subcontractors or sublicensees (excluding Astellas, its Affiliates, and Sublicensees as licensees or sublicensees of Medivation hereunder), or the officers, directors, employees, or

their respective liability for such damages or amounts; and 
 (b) (i) the Exploitation by or on behalf of Medivation or its
Affiliates, (sub)contractors, distributors or sublicensees (excluding such conduct by or on behalf of Astellas, its Affiliates and Sublicensees as licensees or sublicensees of Medivation hereunder) of any Product (or the Collaboration Molecule
contained therein) for the benefit of any Terminated Region following the applicable effective date of termination; (ii) the exercise or use by or on behalf of Medivation, its Affiliates, (sub)contractors, distributors, licensees, or
sublicensees (excluding such exercise by Astellas, its Affiliates, and Sublicensees as licensees and sublicensees of Medivation hereunder) of rights under any license or right of reference, or in or to any Regulatory Materials, Regulatory Approvals,
Marks or other Information, in each case granted, transferred or made available by or on behalf of Astellas or any of its Affiliates to Medivation following or in connection with termination of this Agreement with respect to any Terminated
Region(s), including pursuant to any post-termination transition agreement. 
 12.2 Indemnification by Astellas. Astellas shall
defend, indemnify, and hold Medivation, its Affiliates, subcontractors, distributors, licensees and sublicensees, and each of their respective officers, directors, employees, and agents, (the “Medivation Indemnitees”) harmless from
and against any and all damages or other amounts payable to a Third Party claimant, as well as any reasonable attorneys’ fees and costs of litigation incurred by such Medivation Indemnitees (collectively, “Medivation Damages”),
all to the extent resulting from any claims, suits, proceedings or causes of action brought by such Third Party (collectively, “Medivation Claims”) against such Medivation Indemnitee that arise from or are based on: (a) the
Exploitation of Collaboration Molecules or Products by Astellas or its Affiliates, subcontractors, Distributors or Sublicensees for the benefit of the Licensed Territory, but excluding any Shared Territory Activities; (b) a breach of any of
Astellas’s representations, warranties, and obligations under the Agreement; (c) the willful misconduct or grossly negligent acts of Astellas or its Affiliates, subcontractors, Distributors, or Sublicensees, or the officers, directors,

providing notification pursuant to the previous sentence results in prejudice to the Indemnifying Party. At its option, the Indemnifying Party may assume the defense of any Claim for which
indemnity is being sought by giving written notice to the Indemnified Party within [*] days after receipt of the notice of the Claim. The assumption of defense of the Claim shall not be construed as an acknowledgment that the Indemnifying Party is
liable to indemnify any Indemnified Party in respect of the Claim, nor shall it constitute waiver by the Indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. The Indemnified Party shall
provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense. The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole
expense; provided, however, the Indemnifying Party shall have the right to assume and conduct the defense of the Claim with counsel of its choice. The Indemnifying Party shall not settle any Claim without the prior written consent of the Indemnified
Party, not to be unreasonably withheld, unless the settlement involves only the payment of money. The Indemnified Party shall not settle any such Claim without the prior written consent of the Indemnifying Party, which consent shall not be
unreasonably withheld. If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (a) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with
respect to the Claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (b) the Indemnified
Party reserves any right it may have under this Article 12 to obtain indemnification from the Indemnified Party. 
 12.4 Certain Third
Party Claims Related To Products In The Shared Territory. The Parties shall share equally any Shared Program Damages. With respect to any Shared Program Damages incurred by a Party (or any of its Indemnified Persons) during the Term, such Shared
Program Damages shall be deemed to constitute (and shall be included in) Joint Development Costs, Joint Commercialization Costs and/or Joint Medical Affairs Costs, as applicable (and the Parties shall cooperate in good faith to allocate such
amount(s) to the appropriate cost category). After the Term, each Party shall reimburse the other Party for fifty percent (50%) of any Shared Program Costs incurred by such Party (or any of its Indemnified Persons) no later than [*] days after
receipt of reasonable documentation evidencing such amounts. If either Party receives notice of a Third party claim that arises from or is based on any Shared Program Activities, such party shall inform the other Party in writing as soon as
reasonably practicable, and the Parties shall discuss a strategy on how to defend against such Third Party claim. 
 12.5 Insurance.
Each Party shall procure and maintain insurance, including product liability insurance, with respect to its activities hereunder and which are consistent with normal business practices of prudent companies similarly situated at all times during
which any Product is being clinically tested in human subjects or commercially distributed or sold. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification
obligations under this Article 12. Each Party shall provide the other with written evidence of such insurance upon request. Each Party shall provide the other with written notice at least [*] days prior to the cancellation, non-renewal or material change in such insurance or self-insurance which materially adversely affects the rights of the other Party hereunder. 

ARTICLE 13 

CONFIDENTIALITY 

13.1 Product Information. The Parties recognize the importance of establishing mutually agreeable rules and procedures concerning the
disclosure and dissemination of Information owned or Controlled by either Party or any of its Affiliates relating specifically to [*] (the “Product Information”). For clarity, Product Information includes any such Information
generated by or on behalf of either Party or any of its Affiliates or disclosed by or on behalf of one Party or any of its Affiliates to the other Party or any of its Affiliates (including any such Information disclosed under an Existing
Confidentiality Agreement), in each case whether prior to or during the Term of this Agreement. Except as [*] by this Article 13 or any other provision of this Agreement, each Party and its Affiliates shall have the right (a) to [*] to one or
more Third Parties in [*] and [*], subject to that Party’s obligations with respect to Third Party subcontractors pursuant to Sections 3.6, 6.8 and 7.9, and (b) to use [*] in any manner consistent with the terms and conditions (including

that are set forth in Section 13.4 and (ii) in the case of the data and results of Clinical Trials and Nonclinical Studies with respect to any Collaboration Molecule or Product (whether
conducted prior to or during the Term of this Agreement), the procedures and restrictions set forth in Section 13.5. In addition, the JSC may from time to time establish additional procedures or restrictions that govern disclosure of certain
Product Information or use of certain disclosure channels, provided all such procedures and restrictions shall be effective only to the extent they comply with Applicable Law. If this Agreement is terminated with respect to a particular Region or in
its entirety, then any Product Information consisting of Regulatory Materials or Regulatory Approvals that are assigned to Medivation pursuant to Article 14 as result of such termination shall be deemed to be the Confidential Information of
Medivation, and shall remain subject to Sections 13.2 and 13.3. The Parties acknowledge and agree that although this Section 13.1 is intended as a general matter to provide each Party and its Affiliates with [*] to determine [*] of Product
Information (in each case in a manner consistent with this Section 13.1), it is the expectation of each Party that the other Party will at all times take into consideration the [*], in making any such disclosures. Notwithstanding anything
contained in this Section 13.1 to the contrary, neither Party nor any of its Affiliates shall make disclosures of Product Information that [*] the other Party’s intellectual property (including trade secrets, unpublished Patent filings or
invention disclosures) [*]. Nothing in this Section 13.1 shall be deemed to prohibit either Party or any of its Affiliates from making such disclosures as, in such Party’s or its Affiliate’s reasonable judgment, are required by
Applicable Law. 
 13.2 Confidential Information. Except to the extent expressly authorized by this Agreement or otherwise agreed in
writing by the Parties, each Party agrees that, during the Term and for [*] years thereafter, it shall, and shall cause its Affiliates, to keep confidential and not publish or otherwise disclose to any Third Party, and not use for any purpose other
than as provided for in this Agreement or any Ancillary Agreement, any Confidential Information of the other Party or any of its Affiliates, provided that each Party and its Affiliates may disclose the Confidential Information of the other Party or
its Affiliates to the receiving Party’s and its Affiliates’ officers, directors, employees and agents who in each case are bound by commercially reasonable obligations of confidentiality with respect to the use and disclosure of such
Confidential Information. Notwithstanding the foregoing, Confidential Information of a Party or its Affiliate shall exclude that portion of such information or materials that the receiving Party (or the receiving Party’s Affiliate) can
demonstrate by competent written proof: 
 (a) was already known to the receiving Party or its Affiliate, other than under an
obligation of confidentiality, at the time of disclosure by the other Party; 
 (b) was generally available to the public or
otherwise part of the public domain at the time of its disclosure to the receiving Party; 
 (c) became generally available to the
public or otherwise part of the public domain after its disclosure and other than through any wrongful act, fault, or negligence of the receiving Party; 

(d) is subsequently disclosed to the receiving Party or its Affiliate by a Third Party without obligations of confidentiality with
respect thereto; or 
 (e) is independently discovered or developed by the receiving Party or its Affiliate without the aid,
application, or use of Confidential Information.

 62 








 (c) responding to a valid order of a court of competent jurisdiction or other competent
authority; provided that the receiving Party shall first have given to the disclosing Party notice and a reasonable opportunity to quash the order or obtain a protective order requiring that the Confidential Information be held in confidence
or used only for the purpose for which the order was issued; and provided further that if such order is not quashed or a protective order is not obtained, the Confidential Information disclosed shall be limited to the information that
is legally required to be disclosed; 
 (d) complying with Applicable Law, including regulations promulgated by securities exchanges;

 (e) disclosure to its Affiliates and Third Parties only on a need-to-know basis and solely in connection with the performance by
the disclosing Party of its obligations or the exercise of its rights under this Agreement (including with respect to development, manufacturing and commercialization of Collaboration Molecules and Products), provided that each disclosee, prior to
any such disclosure, must be bound by obligations of confidentiality and non-use at least as equivalent in scope as those set forth in Section 13.1 and 13.2, except [*] may be [*] as can reasonably be [*], but in any case [*] shall have a [*]
that is [*]; 
 (f) disclosure of the material terms of this Agreement to any bona fide potential or actual investor, investment
banker, acquirer, merger partner, Sublicensee, collaborator or other potential or actual financial partner; provided that each disclosee must be bound by obligations of confidentiality and non-use at least as equivalent in scope as those set forth
in Section 13.1 and 13.2 prior to any such disclosure, except [*] may be [*] as can reasonably be [*], but in any case [*] shall have [*] that is [*]; 

(g) disclosure of any Collaboration results or status reports (including data from any Clinical Trials) to any bona fide potential or
actual investor, investment banker, acquirer, merger partner, Sublicensee, collaborator or other potential or actual financial partner; provided that (i) each disclosee must be bound by obligations of confidentiality and non-use at least as
equivalent in scope as those set forth in Section 13.1 and 13.2 prior to any such disclosure, except [*] may be [*] as can reasonably be [*], but in any case [*] shall have a [*] that is [*], and (ii) in the case of Medivation’s
disclosure, Medivation submits the contents of such proposed disclosure to Astellas at least [*] days prior to such disclosure, but Medivation shall not be required to disclose the identity of the disclosee; and 

(h) in the case of Medivation, complying with the terms of the UCLA Agreement. 

Notwithstanding the foregoing, in the event that a Party is required to make a disclosure of the other Party’s Confidential Information
pursuant to Sections 13.3(a), 13.3(b) or 13.3(d), it will, except where impracticable, give reasonable advance notice to the other Party of such disclosure and use reasonable efforts to secure confidential treatment of such information. In any
event, the Parties agree to take all reasonable action to avoid disclosure of Confidential Information hereunder. 
 13.4 Terms of
Agreement. 
 (a) The Parties agree that the material terms of this Agreement are the Confidential Information of both Parties
(and shall not constitute Product Information), subject to the special authorized disclosure provisions set forth in Section 13.3 and this Section 13.4. The Parties have agreed to make a joint public announcement of the execution of this
Agreement substantially in the form of the press release attached as Exhibit 13.4 on or within two (2) trading days after the Effective Date. 

(b) After release of such press release, if either Party or any of its Affiliates desires to make a press release or other similar
public announcement concerning the material terms of this Agreement or any activities under this Agreement, such Party shall give reasonable prior advance notice of the proposed text of such press release or announcement to the other Party for its
prior review and approval (except as otherwise provided herein), such approval not to be unreasonably withheld, except that, subject to Section 13.4(c), in the case of a press release or governmental filing required by law, the disclosing Party
shall provide the other Party with such advance notice

as it reasonably can and shall not be required to obtain approval therefor. A Party commenting on such a proposed press release or announcement shall provide its comments, if any, within [*]
Business Days after receiving the press release for review. Each Party shall have the right to make a press release announcing the achievement of each milestone under this Agreement as it is achieved, and the achievements of Regulatory Approvals as
they occur, subject only to the review procedure set forth in the preceding sentence. In relation to a Party’s review of such a proposed press release or announcement, the Party may make specific, reasonable comments on such proposed press
release or announcement within the prescribed time for commentary, but shall not withhold its approval to disclosure of any information that is required by Applicable Law to be disclosed. Neither Party shall be required to seek the permission of the
other Party to repeat any information regarding the terms of this Agreement that have already been publicly disclosed by such Party or such Party’s Affiliate, or by the other Party or any of its Affiliates, in accordance with this
Section 13.4. 
 (c) The Parties acknowledge that either or both Parties may be obligated to make a filing (including to file a
copy of this Agreement) with the SEC or other Governmental Authorities. Each Party shall be entitled to make such a required filing, provided that it requests confidential treatment of at least the commercial terms and sensitive technical terms
hereof and thereof to the extent such confidential treatment is reasonably available to such Party. In the event of any such filing, each Party will provide the other Party with a copy of the Agreement marked to show provisions for which such Party
intends to seek confidential treatment and shall reasonably consider and incorporate the other Party’s comments thereon to the extent consistent with the legal requirements governing redaction of information from material agreements that must
be publicly filed. 
 13.5 Public Disclosures of Data. Neither Party nor any of its Affiliates shall, except as may be required by
Applicable Law in the reasonable judgment of such Party or its Affiliates and its or their counsel, publicly disclose data or results of Clinical Trials or Nonclinical Studies that have not already been publicly disclosed with respect to any
Collaboration Molecule or Product (whether conducted prior to or during the Term of this Agreement), except as provided in this Section 13.5. 

(a) Press Releases. The Parties shall coordinate to issue a joint press release covering the top line results of all material Clinical
Trials or Nonclinical Studies as quickly as possible following finalization and receipt of such results. The content of such press releases shall be determined by mutual agreement of the Parties. If either Party believes disclosure of such results
should be deferred to an upcoming scientific or medical conference, the Parties shall confer diligently and in good faith to attempt to reach agreement on that point. 

(b) Scientific and Medical Conferences. All presentations of such data and results at scientific and medical conferences that are
international in character or that relate to the United States shall be by mutual agreement of the Parties. 
 (c) Publications.
Publications of such data and results in peer-reviewed journals (“Publications”) shall be made only pursuant to this Section 13.5(c). The Party proposing a Publication shall provide the other Party the opportunity to review the
proposed Publication at least [*] days prior to the earlier of its intended submission for publication. If the other Party offers no comments on the Publication, the submitting Party may submit the Publication [*] days after it provided the
Publication to the reviewing Party (or earlier, with the written consent of the reviewing Party). The submitting Party shall consider the comments of the reviewing Party in good faith. If the Parties are unable to agree upon any aspect of the
Publication, including its form, content, timing (including with respect to additional time required for seeking patent protection for inventions disclosed in the Publication), or proposed medium of publication, either Party may refer the dispute to
the JMAC, which shall resolve the dispute in accordance with Section 2.5(d) in the best interests of the Development and Commercialization of the Collaboration Molecules and the Products and in a manner designed to the extent possible to enable
each Party to comply with its publication policies. The submitting Party shall provide the other Party a copy of the Publication at the time of the submission. Notwithstanding the foregoing, the JMAC shall not have the right to authorize the
publication of either Party’s Confidential Information without such Party’s consent, except that this restriction shall not restrict the JMAC from authorizing any publication of any Clinical Trial results. Each Party agrees to acknowledge
the contributions of the other Party, and the employees of the other Party, in all publications as scientifically appropriate.

 ARTICLE 14 

TERM AND TERMINATION 

14.1 Term. This Agreement shall become effective on the Effective Date and, unless earlier terminated pursuant to this Article 14,
shall expire (a) in the Shared Territory, at such time Astellas notifies Medivation of Astellas’s ceasing permanently to sell Products in the Shared Territory and (b) in the Licensed Territory, on a country-by-country basis at the end
of the applicable Royalty Term (the “Term”). 
 14.2 Termination by Astellas. 

(a) At Will. Astellas shall have the right to terminate this Agreement [*] upon [*] days prior written notice, which notice may be
given to Medivation (i) at any time after the first anniversary of the first commercial sale of a Product in [*] or (ii) at any earlier time with Medivation’s written consent (such termination, a “Termination at
Will”). 
 (b) For Regulatory-Related Reasons. Astellas shall have the right to terminate this Agreement on a
Region-by-Region basis upon [*] days prior written notice to Medivation if Astellas concludes, reasonably and in good faith, that [*] to [*] after the [*] (i) make it [*] that a [*] will [*] in a [*], or (ii) make it [*] that a [*] will
[*] in a [*] or with a [*] which may [*] the [*] of the [*] in the [*]; provided that if at such time there is more than one Active Product in such Region, Astellas may terminate the Region pursuant to this Section 14.2(b) only if clause
(i) or (ii) is satisfied with respect to all such Active Products in such Region. For the avoidance of doubt, Astellas’s conclusion pursuant to the previous sentence may be based upon such [*] to [*] after the [*] either alone or in
the aggregate with other [*] prior to, on or after the [*]. 
 (c) For [*]. Astellas shall have the right to terminate this Agreement
on a Region-by-Region basis upon [*] days prior written notice to Medivation if (i) as a result of an action, event, circumstance or development with respect to the filing, prosecution or maintenance of one of the patent applications included
in the Collaboration Patents that arises or becomes known after the Effective Date or (ii) on the basis of any information known to Medivation but not disclosed to Astellas prior to the Effective Date, with respect to a country in the Region,
in either case ((i) or (ii)) it is [*] that [*] in the Collaboration Patents will issue in such country that will contain a claim [*] to [*] of [*] with respect to a [*] in such country; provided that if at such time there is more than one Active
Product in such Region, Astellas may terminate the Region pursuant to this Section 14.2(c) only if such condition is satisfied with respect to all such Active Products in such Region. Any dispute between the Parties as whether [*] shall be
resolved by a Patent Expert pursuant to Section 15.10. 
 (d) For [*]. Subject to the terms of this Section 14.2(d),
Astellas may terminate this Agreement on a Region-by-Region basis upon [*] days prior written notice to Medivation if (i) as a result of an action, event, circumstance or development that occurs or becomes known after the Effective Date or
(ii) on the basis of any information known to Medivation but not disclosed to Astellas prior to the Effective Date, in each case ((i) or (ii)) (A) it is [*] that it and its Affiliates, Distributors, and Sublicensees cannot [*] in a country
in such Region without [*] the [*] or (B) a Third Party [*] alleging that the [*] with respect to a country in such Region by or on behalf of Astellas, its Affiliates, Distributors or Sublicensees under this Agreement [*] its [*] and it is [*]
that [*] in [*]. Prior to exercising this termination right, Astellas must consult with Medivation regarding the applicable circumstances described in clause (A) or (B) (as applicable), and must use Diligent Efforts to resolve such
circumstances in a manner that would permit the [*] in the applicable country [*], unless there is [*] that [*] will be [*]. Any dispute between the Parties as whether the requirements of clause (A) or clause (B) have been satisfied shall
be resolved by a Patent Expert pursuant to Section 15.10. 
 (e) Conferral Period Prior to Notice of Termination. Prior to
providing any notice of termination (with respect to any Region(s) or this Agreement in its entirety) pursuant to any clause of this Section 14.2, Astellas shall notify Medivation of its intent to do so. Promptly following Astellas’s
notice of intent to terminate, and in any event within [*] Business Days thereof or such other period as the Parties may agree, at Medivation’s written request, the Parties shall discuss Astellas’s intention to terminate. Following such
discussion (or following the expiration of the applicable conferral period), Astellas shall have the right to provide to 

  
 [*] = Certain confidential
information contained in this document, marked by brackets, has been omitted and filed separately with the securities and exchange commission pursuant to rule 24b-2 of the securities exchange act of 1934, as amended. 


  
 65 








 
Medivation a notice of termination pursuant to any clause of Section 14.2 (to the extent permitted by the applicable notice timeline and by the applicable criteria for termination). For the
avoidance of doubt, Astellas’s notice that it intends to terminate pursuant to Section 14.2, which notice is provided pursuant to the first sentence of this Section 14.2(e), shall not be deemed to be a termination notice and shall not
obligate Astellas to terminate this Agreement.  
 14.3 Termination by Either Party for Breach or Insolvency. 

(a) Breach. Subject to Section 14.3(b), Medivation shall have the right to terminate this Agreement in its entirety or with
respect to a Region upon written notice to Astellas if Astellas materially breaches its obligations under this Agreement with respect to such Region and, after receiving written notice from Medivation identifying such material breach by Astellas in
reasonable detail, fails to cure such material breach within [*] days from the date of such notice (or within [*] days from the date of such notice in the event such material breach is solely based upon Astellas’s failure to pay any amounts due
Medivation hereunder). Subject to Section 14.3(b), Astellas shall have the right to terminate this Agreement in its entirety or with respect to a Region upon written notice to Medivation if Medivation materially breaches its obligations under
this Agreement with respect to such Region and, after receiving written notice from Astellas identifying such material breach by Medivation in reasonable detail of its obligations under this Agreement, fails to cure such material breach within [*]
days from the date of such notice (or within [*] days from the date of such notice in the event such material breach is solely based upon Medivation’s failure to pay any amounts due Astellas hereunder). 

(b) Disputed Breach. If the alleged breaching Party disputes in good faith the existence or materiality of a breach specified in a
notice provided by the other Party in accordance with Section 14.3(a), and such alleged breaching Party provides the other Party notice of such dispute within such [*] day period, then the non-breaching Party shall not have the right to
terminate this Agreement under Section 14.3(a) unless and until an arbitrator, in accordance with Article 15, has determined that the alleged breaching Party has materially breached the Agreement and that such Party fails to cure such breach
within [*] days following such arbitrator’s decision (except to the extent such breach involves the failure to make a payment when due, which breach must be cured within [*] days following such arbitrator’s decision). It is understood and
agreed that during the pendency of such dispute, all of the terms and conditions of this Agreement shall remain in effect. 
 (c)
Disfavored Remedy. The Parties agree that termination pursuant to this Section 14.3 is a remedy to be invoked only if the breach cannot be adequately remedied through a combination of specific performance and the payment of money damages.
In that regard, if the money damages payable under this Agreement by reason of a breach were materially limited by reason of Section 16.11 (for reasons other than the exclusion for punitive damages), it shall be assumed that the payment of
money damages was not an adequate remedy for the breach unless the breaching Party elects to waive the protections of Section 16.11 (other than with respect to punitive damages) and pay the resulting amounts. 

(d) Insolvency. If, at any time during the Term (i) a case is commenced by or against either Party under Title 11, United States
Code, as amended, or analogous provisions of Applicable Law outside the United States (the “Bankruptcy Code”) and, in the event of an involuntary case under the Bankruptcy Code, such case is not dismissed within [*] days after the
commencement thereof, (ii) either Party files for or is subject to the institution of bankruptcy, liquidation or receivership proceedings (other than a case under the Bankruptcy Code), (iii) either Party assigns all or a substantial
portion of its assets for the benefit of creditors, (iv) a receiver or custodian is appointed for either Party’s business, or (v) a substantial portion of either Party’s business is subject to attachment or similar process; then,
in any such case ((i), (ii), (iii), (iv) or (v)), the other Party may terminate this Agreement upon written notice to the extent permitted under Applicable Law. 

14.4 Relationship Between Regions. 

(a) Relationship Between U.S./EU/Japan and Rest of Territory. Notwithstanding anything to the contrary in Section 14.2 or 14.3, if
Astellas terminates this Agreement pursuant to Section 14.2 or 14.3 with respect to each of (a) the U.S., (b) the EU and (c) Japan, then Astellas, at its election, may terminate this Agreement in its entirety at any time
following the termination of the third such Region, effective upon [*] days’ 

  
 [*] = Certain confidential
information contained in this document, marked by brackets, has been omitted and filed separately with the securities and exchange commission pursuant to rule 24b-2 of the securities exchange act of 1934, as amended. 


  
 66 








 
prior written notice to Medivation. If this Agreement is terminated in its entirety pursuant to this Section 14.4(a) and if Astellas terminated this Agreement with respect to the U.S.
pursuant to Section 14.3, then the termination of this Agreement in its entirety pursuant to this Section 14.4(a) shall be deemed to be a termination pursuant to Section 14.3 by Astellas. 

(b) Relationship Between [*] and [*]. 

(i) Medivation Termination Right. In the event Astellas terminates this Agreement with respect to [*] pursuant to a Termination at
Will, then Medivation, at its election, may terminate this Agreement with respect to [*], at any time within [*] days after Medivation’s receipt of Astellas’s notice of termination, effective at the same time that the Agreement terminates
with respect to [*]. In the event Astellas terminates this Agreement with respect to [*] pursuant to a Termination at Will, then Medivation, at its election, may terminate this Agreement with respect to [*], at any time within [*] days after
Medivation’s receipt of Astellas’s notice of termination, effective at the same time that the Agreement terminates with respect to [*]. 

(ii) Astellas Right to Seek Medivation Precommitment. Astellas shall have the right to obtain from Medivation binding guidance
pursuant to the procedures set forth in this Section 14.4(b)(ii) with respect to whether, if Astellas were to terminate this Agreement with respect to [*] or [*], Medivation would terminate this Agreement with respect to [*] pursuant to
Medivation’s rights under Section 14.4(b)(i): If Astellas notifies Medivation that Astellas is considering terminating this Agreement with respect to [*] or [*] pursuant to a Termination at Will, then Medivation shall within [*] days
thereafter notify Astellas whether Medivation would, were it to receive such a termination notice from Astellas, exercise its right under Section 14.4(b)(i) to terminate this Agreement with respect to [*]. Such statement by Medivation shall be
binding on Medivation, provided that it actually receives such a termination notice from Astellas within [*] days thereafter. For the avoidance of doubt, Astellas’s notification that it is considering terminating this Agreement shall not be
deemed to be a termination notice and shall not obligate Astellas to terminate this Agreement. 
 14.5 Effects of Termination of the
Agreement. Upon termination of this Agreement with respect to one or more Regions or in its entirety (the “Terminated Regions”; with the entire Territory being the Terminated Regions in the event of termination of this Agreement
in its entirety), the following shall apply with respect to the Terminated Regions (in addition to any other rights and obligations under this Article 14 or otherwise under this Agreement with respect to such termination): 

(a) Licenses. The licenses granted in Article 8 shall terminate with respect to the Terminated Regions, except that limited license
rights shall remain in effect in the Terminated Region(s) solely for the limited purpose of allowing Astellas to Develop or Manufacture Product(s) (including any intermediate thereof or any API or other material contained therein) in the Terminated
Region(s) for sale or distribution thereof in any Region which has not been terminated. Notwithstanding the foregoing, effective upon the effective date of termination of this Agreement with respect to any Terminated Region, Astellas hereby grants
to Medivation, effective only upon such termination, an exclusive, fully-paid, perpetual, irrevocable, royalty-free license, with the right to grant multiple tiers of sublicenses, under the Astellas Technology (along with any other Patents
Controlled by Astellas that, absent a license, would be infringed by the manufacture, use, or sale of a Reversion Product in a Terminated Region) as such Patents, Know-How and interests in Patents and Know-How exist as of the effective date of
termination, to research, develop, make, have made, use, import, export, offer for sale, and sell Reversion Products for the Field with respect to the applicable Terminated Regions. Medivation covenants that it will not knowingly use or practice any
of Astellas’s intellectual property rights licensed to it under this Section 14.5(a) in a manner that would constitute infringement or misappropriation of such intellectual property rights except for the purposes expressly permitted in the
license grant. 
 (b) Marks. Astellas shall assign to Medivation all right, title and interest in and to those Marks used exclusively
with Reversion Products and used exclusively in the Terminated Regions (excluding any such Marks that include, in whole or part, any corporate name or logo of Astellas or its Affiliate or Sublicensee).

information contained in this document, marked by brackets, has been omitted and filed separately with the securities and exchange commission pursuant to rule 24b-2 of the securities exchange act of 1934, as amended. 


  
 67 








 (c) Regulatory Materials. Astellas shall grant to Medivation a right of reference under
all Regulatory Materials and Regulatory Approvals for Reversion Products in the Terminated Regions that are Controlled by Astellas or its Affiliates or Sublicensees, unless and until assigned to Medivation pursuant to any Transition Agreement. 

(d) Conduct During Termination Notice Period. 

(i) Following any notice of termination permitted under this Article 14 other than any termination pursuant to Section 14.3,
during any applicable termination notice period (the applicable “Termination Notice Period”), each Party shall continue to perform all of its obligations under this Agreement, including performing all activities allocated to it
pursuant to the Joint Development Plan, Joint Manufacturing Plan, Joint Medical Affairs Plan and Joint Commercialization Plan, respectively, then in effect in accordance with the terms and conditions of this Agreement. In such circumstances each
Party shall also continue to bear its share of all Joint Development Costs, Joint Medical Affairs Costs and Joint Commercialization Costs incurred during the Termination Notice Period, except that in the case of termination pursuant to
Section 14.2(d), each Party shall bear its share of all such costs incurred during the [*] day period following the notice of termination. 

(ii) Notwithstanding clause (i) above, to the extent that Astellas reasonably and in good faith concludes that (A) the
continued performance during any Termination Notice Period of any or all such activities described in clause (i) above (except for activities relating to the Manufacture and supply of Products), including the conduct of a Clinical Trial (the
“Suspended Activities”), may [*] to [*] beyond those that would be [*] by [*], and (B) any offer made by Medivation to [*] and other [*] (which would be in addition to [*]) would not be sufficient under the circumstances to
[*], (w) Astellas shall identify the Suspended Activities to Medivation in writing, (x) Astellas shall not be obligated to perform the Suspended Activities (but if a Suspended Activity is the conduct of any Clinical Trial, Astellas shall
reasonably cooperate with Medivation to transfer sponsorship of such Clinical Trial to Medivation or shall conduct an orderly wind-down of the Clinical Trial, as appropriate), (y) Astellas may elect, in its sole discretion, the manner of
discharging its responsibility to bear its share of Joint Development Costs, Joint Medical Affairs Costs and Joint Commercialization Costs incurred during the applicable Termination Notice Period (or the [*] day period following notice of
termination, in the case of termination pursuant to Section 14.2(d)) with respect to Suspended Activities, either (1) by making payment with respect thereto as would otherwise be required pursuant to the procedures set forth in Sections
9.2 and 9.3 or (2) by [*] a [*] equal to [*] as [*] are projected in the [*] applicable at the time the applicable notice of termination was provided and (z) this Agreement shall be deemed to have been terminated effective as of the date
of the termination notice solely for the purposes of the Parties’ indemnity and cost sharing obligations pursuant to Article 12. 

(iii) During the applicable Termination Notice Period, neither Party shall make any statement to any Person, whether written, verbal,
electronic or otherwise, that disparages any Product, the work performed by either Party under this Agreement, or the other Party. 
 (e)
Transition Agreement. In connection with the termination of this Agreement in its entirety or with respect to one or more Regions other than by Astellas pursuant to Section 14.3, the Parties shall enter into a written agreement (the
“Transition Agreement”) that would effectuate the terms and conditions of this Section 14.5(e) and would include other reasonable terms and conditions, including terms allocating costs and expenses, describing the Parties’
indemnification obligations, setting forth the Parties’ obligations with respect to unauthorized sales, and setting forth other coordination obligations. If, despite such efforts, the Parties are unable to agree upon such terms and conditions
within [*] days from the effective date of the termination, either Party may refer the dispute for resolution by arbitration in accordance with Section 15.2, and the arbitrator shall have the authority to require the Parties to execute a
Transition Agreement in the form approved by the arbitrator. 
 (i) Transition Assistance. The Transition Agreement shall require
Astellas to, at no cost to Medivation, provide reasonable consultation and assistance for a period of no more than [*] days for the purpose of disclosing and providing to Medivation, all Astellas Know-How not already in Medivation’s possession
that is relevant to the Reversion Products and the applicable Terminated Regions, and, at Medivation’s request, all then-existing commercial arrangements to the extent relating solely and specifically to the Reversion Products and

 68 








 
the applicable Terminated Regions that Astellas is able, using reasonable commercial efforts, to disclose and provide to Medivation, in each case, to the extent reasonably necessary or useful for
Medivation to commence or continue researching, Developing, Manufacturing, or Commercializing the Reversion Products with respect to the applicable Terminated Regions. The foregoing shall include, without limitation, assigning, upon request of
Medivation, any agreements with Third Party suppliers or vendors to the extent they solely and specifically cover the supply or sale of Reversion Products in applicable Terminated Regions. If any such contract between Astellas and a Third Party is
not assignable to Medivation (whether by such contract’s terms or because such contract does not relate specifically to Reversion Products or the Terminated Regions) but is otherwise reasonably necessary or useful for Medivation to commence or
continue researching, Developing, Manufacturing, or Commercializing Reversion Products with respect to the Terminated Regions, then Astellas shall reasonably cooperate with Medivation in Medivation’s efforts to [*]. Unless and until the
necessary Third Party Manufacturing agreements are assigned to Medivation pursuant to the preceding sentence, or if Astellas Manufactures the Reversion Products itself (and thus there is no contract to assign), the Transition Agreement shall require
Astellas to supply such bulk Collaboration Molecule or finished Reversion Product, as applicable, to Medivation for a reasonable period (not to exceed [*]) to enable Medivation to establish an alternate, validated source of supply for the applicable
Reversion Products. The cost to Medivation for such supply shall be [*]. Notwithstanding any other term or condition of this Section 14.5(e), to the extent that Astellas, after consultation with Medivation, reasonably and in good faith
concludes that (A) performance of any of the obligations (except for obligations described in this Section 14.5(e)(i) relating to the Manufacture and supply of Reversion Products) imposed on Astellas under this Section 14.5(e) or that
would be imposed on Astellas under the Transition Agreement pursuant to this Section 14.5(e) may [*] to [*] beyond those that would be [*] by [*], and (B) any offer made by Medivation to provide [*] (which would be in addition to [*])
would not be sufficient under the circumstances to [*], Astellas may elect not to perform such obligations and/or decline to include such obligations in the Transition Agreement. 

(ii) Regulatory Materials. The Transition Agreement shall require Astellas to transfer and assign to Medivation all Regulatory
Materials and Regulatory Approvals in and for the benefit of the Terminated Regions solely relating to Reversion Products that are owned by Astellas or its Affiliates. The Transition Agreement shall contain terms governing the coordination of their
ongoing regulatory responsibilities with respect to Collaboration Molecules and Products. 
 (f) [*]. If this Agreement is terminated
other than by Astellas pursuant to Section 14.3, then Astellas shall [*]. Astellas may elect at any time, in its sole discretion, the manner of [*], either (x) by [*] or (y) by [*]. After the expiration of the applicable Termination
Notice Period, except as otherwise provided in this Section 14.5 and in Section 14.8 below, Astellas shall no longer have any obligations or rights to perform any Development activities, Medical Affairs Activities or Commercialization
activities under this Agreement and shall have no further obligations to bear or reimburse any Joint Development Costs, Joint Medical Affairs Costs and/or Joint Commercialization Costs or other costs or expenses incurred, in each case, after the
applicable Termination Notice Period with respect to the Development or Commercialization (including Manufacturing) of, or Medical Affairs Activities in support of, Products. 

(g) Third-Party Agreements. Medivation shall pay such amounts to Astellas that Astellas is obligated to pay to any Third Parties
(including royalties, milestones and other amounts) under any Third Party agreements that are applicable to the grant to Medivation of any (sub)license, right of reference or other right provided in this Section 14.5 or the Transition
Agreement, or that are applicable to the exercise by Medivation or any of its Affiliates or sublicensees of any sublicense or other right with respect thereto, and in each instance Medivation shall make the requisite payments to Astellas and provide
the necessary reporting information to Astellas in sufficient time to enable Astellas to comply with its obligations under the applicable Third Party agreements. In addition, Medivation shall comply with any other obligations included in the Third
Party agreements that are applicable to the grant to Medivation of such (sub)license, right of reference or other right, and any exercise of such (sub)license, right of reference or other right by Medivation or any of its Affiliates or sublicensees
shall be subject to the terms and conditions of such Third Party agreements.

 (h) Remaining Inventories. 

(i) Astellas shall be entitled, during the [*] days following termination of this Agreement, to finish any work-in-progress and to sell in the Terminated Regions any inventory of Product that remains on hand as of the effective date of the termination. Astellas shall pay Medivation
the royalties applicable to such sales in accordance with the terms and conditions of this Agreement. 
 (ii) At any time within [*]
days after the effective date of termination with respect to any Terminated Region(s), Medivation shall have the right, upon written notification to Astellas, to purchase from Astellas any or all of the inventory of Collaboration Molecules and
Reversion Products held by Astellas with respect to such Terminated Region(s) as of the date of such notice solely for distribution in the Terminated Region(s) and not for distribution in other countries (that are not committed to be supplied to any
Third Party or Sublicensee as of such date) at a price equal to [*]. 
 14.6 Other Remedies. Termination or expiration of this
Agreement for any reason shall not release either Party from any liability or obligation that already has accrued prior to such expiration or termination, nor affect the survival of any provision hereof to the extent it is expressly stated to
survive such termination. Termination or expiration of this Agreement for any reason shall not constitute a waiver or release of, or otherwise be deemed to prejudice or adversely affect, any rights, remedies or claims, whether for damages or
otherwise, that a Party may have hereunder or that may arise out of or in connection with such termination or expiration. 
 14.7 Rights
in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by Medivation and Astellas are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to
“intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that each Party, as licensee of certain rights under this Agreement, shall retain and may fully exercise all of its rights and
elections under the U.S. Bankruptcy Code. The Parties further agree that, in the event of the commencement a bankruptcy proceeding by or against a Party (such Party, the “Bankrupt Party”) under the U.S. Bankruptcy Code, the other
Party shall be entitled to a complete duplicate of (or complete access to, as appropriate) any intellectual property licensed to such other Party and all embodiments of such intellectual property, which, if not already in such other Party’s
possession, shall be promptly delivered to it (a) upon any such commencement of a bankruptcy proceeding upon such other Party’s written request therefor, unless the Bankrupt Party elects to continue to perform all of its obligations under
this Agreement or (b) if not delivered under clause (a), following the rejection of this Agreement by the Bankrupt Party upon written request therefor by the other Party. The Parties acknowledge and agree that of the milestones and royalties to
be paid pursuant to Article 9, only the sales milestones contained in Section 9.5 and the royalties contained in Section 9.6 shall constitute royalties within the meaning of Bankruptcy Code § 365(n) with respect to the licenses of
intellectual property hereunder. 
 14.8 Survival. Termination or expiration of this Agreement shall not affect rights or obligations
of the Parties under this Agreement that have accrued prior to the date of termination or expiration of this Agreement. Notwithstanding anything to the contrary, the following provisions shall survive and apply after expiration or termination of
this Agreement in its entirety: Sections 9.6(e), 9.11, 9.12, 10.1, 10.2 (solely with respect to Joint Inventions), 10.3(d), 10.3(e) (solely with respect to the prosecution of Joint Patents), 11.5, 14.5, 14.6, 14.7, 14.8, 16.1, 16.3, 16.4, 16.5,

under this Agreement shall be settled pursuant to Section 15.2 or 15.9, as applicable). In addition, the other applicable provisions of Article 9 shall survive such expiration or termination of this Agreement in its entirety to the extent
required to make final reimbursements, reconciliations or other payments incurred or accrued prior to the date of termination or expiration. For any surviving provisions requiring action or decision by a Committee or an Executive Officer, each Party

Terminated Regions (to the extent they would survive and apply in the event the Agreement expires or is terminated in its entirety), and all provisions not surviving in accordance with the foregoing shall terminate upon termination of this Agreement
with respect to the applicable Region(s) and be of no further force and effect (and for the avoidance of doubt all provisions of this Agreement shall remain in effect with respect to any Region(s) that are not terminated).

 ARTICLE 15 

DISPUTE RESOLUTION 

15.1 Disputes. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this
Agreement in an expedient manner by mutual cooperation and without resort to litigation. In the event of any disputes, controversies or differences which may arise between the Parties out of or in relation to or in connection with this Agreement
(other than disputes arising from a Committee), including, without limitation, any alleged failure to perform, or breach, of this Agreement, or any issue relating to the interpretation or application of this Agreement, then upon the request of
either Party by written notice, the Parties agree to meet and discuss in good faith a possible resolution thereof, which good faith efforts shall include at least one in-person meeting between the Executive Officers of each Party. If the matter is
not resolved within [*] days following the written request for discussions, either Party may then invoke the provisions of Section 15.2 (or Section 15.9 or 15.10, as appropriate). For the avoidance of doubt, any disputes, controversies or
differences arising from a Committee pursuant to Article 2 shall be resolved solely in accordance with Section 2.7. 
 15.2
Arbitration. Any dispute, controversy, difference or claim which may arise between the Parties and not from a Committee, out of or in relation to or in connection with this Agreement (including, without limitation, arising out of or relating to
the validity, construction, interpretation, enforceability, breach, performance, application or termination of this Agreement) that is not resolved pursuant to Section 15.1, except for a dispute, claim or controversy under Section 15.9 or
15.10, shall be settled by binding arbitration as follows. Either Party, following the end of the [*] day period referenced in Section 15.1, may refer such issue to arbitration by submitting a written notice of such request to the other Party.
Promptly following receipt of such notice, the Parties shall meet and discuss in good faith and agree on an arbitrator to resolve the issue, which arbitrator shall be neutral and independent of both Parties and all of their respective Affiliates,
shall have significant experience and expertise in licensing and partnering agreements in the pharmaceutical and biotechnology industries. If the Parties cannot agree on such arbitrator within [*] days of request by a party for arbitration, then
such arbitrator shall be appointed by JAMS, which arbitrator must meet the foregoing criteria. The place of arbitration shall be San Francisco, California. The proceedings shall be conducted pursuant to the rules set forth by JAMS for such
proceedings. All proceedings and communications shall be in English. The Parties agree that discovery appropriate to the issues in the dispute shall be permitted in the arbitration, including reasonable document requests, pre-hearing exchanges of
information, expert witness disclosures, limited depositions of important witnesses and other appropriate discovery, provided that such discovery shall be limited to the narrower of (a) the scope of discovery agreed to by the Parties, or
if none can be agreed, established by the arbitrator, and (b) such discovery as would be permitted by the Federal Rules of Civil Procedure and is approved by the arbitrator, keeping in mind the goal of an expedited and efficient proceeding. The
arbitration shall be governed by the procedural and substantive law set forth in Section 15.3 and the United States Arbitration Act, 9 U.S.C. §§1-16 to the exclusion of any inconsistent state laws. Either Party may apply to the
arbitrator for interim injunctive relief or may seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending resolution of the matter pursuant to this Article 15. The
Parties shall have the right to be represented by counsel. Any judgment or award rendered by the arbitrator shall be final and binding on the Parties, and shall be governed by the terms and conditions hereof, including the limitation on damages set
forth in Section 16.11. The Parties agree that such a judgment or award may be enforced in any court of competent jurisdiction. The statute of limitations of the State of Delaware applicable to the commencement of a lawsuit shall apply to the
commencement of arbitration under this Article 15. Each Party shall bear its own costs and expenses and attorneys’ fees in the arbitration, except that the arbitrator may order the non-prevailing Party to bear all or an appropriate part
(reflective of the relative success on the issues) of the costs and expenses and reasonable attorneys’ fees incurred by the prevailing Party based on the relative merits of each Party’s positions on the issues in the Dispute. The Party
that does not prevail in the arbitration proceeding shall pay the arbitrator’s fees and expenses and any administrative fees of arbitration. All proceedings and decisions of the arbitrator(s) shall be deemed Confidential Information of each of
the Parties, and shall be subject to Article 13.

 15.3 Governing Law. This Agreement shall be governed by and construed under the
substantive laws of the State of Delaware, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. 

15.4 Award. Any award to be paid by one Party to the other Party as determined by the arbitrator as set forth above under
Section 15.2 shall be promptly paid in U.S. dollars free of any tax, deduction or offset; and any costs, fees or taxes incident to enforcing the award shall, to the maximum extent permitted by law, be charged against the Party resisting
enforcement. Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Article 15, and agrees that, subject to the U.S. Federal Arbitration Act, 9 U.S.C. §§ 1-16, judgment may be entered upon the final
award in the Federal District Court in Northern California and that other courts may award full faith and credit to such judgment in order to enforce such award. The award shall include interest from the date of any damages incurred for breach of
the Agreement, and from the date of the award until paid in full, at a rate fixed by the arbitrator. 
 15.5 Injunctive Relief; Remedy
for Breach of Exclusivity. Nothing in this Article 15 will preclude either Party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary
injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding. Specifically, the
Parties agree that a material breach by either Party of its obligations in Section 8.9 of this Agreement may cause irreparable harm to the other Party, for which damages may not be an adequate remedy. Therefore, in addition to its rights and
remedies otherwise available at law, including, without limitation, the recovery of damages for breach of this Agreement, upon an adequate showing of material breach of such Section 8.9, and without further proof of irreparable harm other than
this acknowledgement, such non-breaching Party shall be entitled to seek (a) immediate equitable relief, specifically including, but not limited to, both interim and permanent restraining orders and injunctions, and (b) such other and
further equitable relief as the court may deem proper under the circumstances. For the avoidance of doubt, nothing in this Section 15.5 shall otherwise limit a breaching Party’s opportunity to cure a material breach as permitted in
accordance with Section 14.3. 
 15.6 Confidentiality. The arbitration proceeding shall be confidential and the arbitrator shall
issue appropriate protective orders to safeguard each Party’s Confidential Information. Except as required by law, no Party shall make (or instruct the arbitrator to make) any public announcement with respect to the proceedings or decision of
the arbitrator without prior written consent of the other Party. The existence of any dispute submitted to arbitration, and the award, shall be kept in confidence by the Parties and the arbitrator, except as required in connection with the
enforcement of such award or as otherwise required by Applicable Law. 
 15.7 Survivability. Any duty to arbitrate under this
Agreement shall remain in effect and be enforceable after termination of this Agreement for any reason. 
 15.8 Jurisdiction. For the
purposes of this Article 15, the Parties acknowledge their diversity (Astellas having its principal places of business in Japan and the state of Illinois and Medivation having its principal place of business in the State of California), and except
as provided in Section 15.9, agree to accept the jurisdiction of any United States District Court located in California for the purposes of enforcing or appealing any awards entered pursuant to this Article 15 and for enforcing the agreements
reflected in this Article 15 and agree not to commence any action, suit or proceeding related thereto except in such courts. 
 15.9
Patent and Trademark Disputes. Notwithstanding Section 15.2 but subject to Section 15.10, any dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any Collaboration Patents or Marks covering
the manufacture, use, importation, offer for sale or sale of Products shall be submitted to a court of competent jurisdiction in the country in which such patent or trademark rights were granted or arose. 

15.10 Patent Expert. Notwithstanding Section 15.2 or Section 15.9, this Section 15.10 shall apply with respect to any
dispute that this Agreement explicitly states is to be resolved by a Patent Expert. Either Party may initiate dispute resolution pursuant to this Section 15.10 with respect to any such dispute by written notice to the

other Party. Promptly following such notice, the Parties shall endeavor diligently and in good faith to agree upon a patent attorney with relevant experience in the field of pharmaceutical
patents to resolve the dispute. Such attorney (and such attorney’s law firm) shall not represent either Party at the time of such selection and shall not have represented either Party during the [*] months prior to such selection. If the
Parties agree upon such an attorney within [*] days of the notice, such attorney shall be the “Patent Expert.” If the Parties are unable to agree upon such an attorney within [*] days of the notice, then each Party shall select one
attorney fulfilling the above criteria, and the attorneys selected by the two Parties shall select a third attorney fulfilling such criteria, which third attorney shall be the “Patent Expert.” The Patent Expert may specify his or
her own procedures for conducting the dispute resolution, provided that there shall not be any ex parte communications except by mutual consent of the Parties. The Patent Expert shall assess his or her costs, fees and expenses against the Party
losing the determination unless he or she believes that neither Party is the clear loser, in which case the Patent Expert shall divide his or her fees, costs and expenses according to his or her sole discretion. The determination of such Patent
Expert with respect to the dispute shall be final and binding upon the Parties. 
 ARTICLE 16 

MISCELLANEOUS 

16.1 Entire Agreement; Amendment. This Agreement, including the Exhibits hereto, sets forth the complete, final and exclusive agreement
and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings between the Parties
existing as of the Effective Date with respect to the subject matter hereof, including, without limitation, the Existing Confidentiality Agreements. The foregoing shall not be interpreted as a waiver of any remedies available to either Party as a
result of any breach, prior to the Effective Date, by the other Party of its obligations pursuant to the Existing Confidentiality Agreements. In the event of any inconsistency between any plan hereunder (including the Joint Development Plan, Joint
Commercialization Plan or Joint Manufacturing Plan) and this Agreement, the terms of this Agreement shall prevail. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written,
between the Parties other than as are set forth herein and therein. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each
Party. 
 16.2 Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the
extent that such performance is prevented or delayed by force majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting force majeure
continues and the nonperforming Party takes reasonable efforts to remove the condition; provided, however, that if the condition constituting force majeure continues for more than [*] consecutive days the other Party shall have the option to
terminate this Agreement immediately upon written notice. For purposes of this Agreement, force majeure shall mean conditions beyond the control of the Parties, including without limitation, an act of God, war, civil commotion, terrorist act, labor
strike or lock-out, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe, and failure of plant or machinery (provided that such failure
could not have been prevented by the exercise of skill, diligence, and prudence that would be reasonably and ordinarily expected from a skilled and experienced person engaged in the same type of undertaking under the same or similar circumstances).
Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a force majeure affecting such Party. 

16.3 Notices. Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to this
Agreement, and shall be addressed to the appropriate Party at the address specified below or such other address as may be specified by such Party in writing in accordance with this Section 16.3, and shall be deemed to have been given for all
purposes (a) when received, if hand-delivered or sent by a reputable international expedited delivery service, or (b) five (5) Business Days after mailing, if mailed by first class certified or registered mail, postage prepaid, return
receipt requested. This Section 16.3 is not intended to govern the day-to-day business communications necessary between the Parties in performing their obligations under the terms of this Agreement.

 16.4 No Strict Construction; Headings. This Agreement has been prepared jointly and shall not be
strictly construed against either Party. Ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision. The headings of each Article and Section in
this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section. 

16.5 Assignment. Neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written
consent of the other, except that a Party may make such an assignment without the other Party’s consent to Affiliates or to a successor to substantially all of the business to which this Agreement relates, whether in a merger, sale of stock,
sale of assets or other transaction. Any permitted successor or assignee of rights and/or obligations hereunder shall, in a writing to the other Party, expressly assume performance of such rights and/or obligations (and in any event, any Party
assigning this Agreement to an Affiliate shall remain bound by the terms and conditions hereof). In the event that a Party is acquired by a Third Party (such Third Party, hereinafter referred to as an “Acquiror”), then the

purposes of the applicable components of the foregoing intellectual property definitions, in all such cases if and only if: (a) [*]; (b) [*]; (c) [*]; and (d) [*]. For clarity, in the event that a Party is acquired by an Acquiror
and each of the criteria described in clauses (a) through (d) is not satisfied, then the intellectual property of such Acquiror shall be included within Medivation Technology (in the case when the acquired Party is Medivation) and Astellas
Technology (in the case when the acquired Party is Astellas). Any permitted assignment shall be binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this
Section 16.5 shall be null, void and of no legal effect.

prohibits Astellas or any of its Affiliates from acquiring securities of Medivation or any of its subsidiaries or other Affiliates by or through (i) a diversified mutual or pension fund or employee benefit plan managed by an independent

 ASTELLAS AND MEDIVATION ENTER INTO WORLDWIDE AGREEMENT TO CO-DEVELOP AND CO-COMMERCIALIZE MDV3100 FOR THE
TREATMENT OF PROSTATE CANCER 
 — Medivation to Receive $110 Million Upfront Cash Payment and Eligible to Receive $655 Million in
Milestone 
 Payments, 50 Percent of U.S. Profits and Double-Digit Royalties on Ex-U.S. Sales — 

— Medivation to Host Conference Call/Webcast Today at 8:30 a.m. Eastern Time — 

TOKYO, JAPAN and SAN FRANCISCO, CA, October, 27, 2009—Astellas Pharma Inc. (“Astellas”) and Medivation, Inc. (Nasdaq: MDVN) announced today
that they have entered into a global agreement to develop and commercialize MDV3100, Medivation’s investigational drug for the treatment of prostate cancer. MDV3100 is currently being evaluated in the Phase 3 AFFIRM clinical trial in men with
castration-resistant prostate cancer who were previously treated with docetaxel-based chemotherapy. 
 Under the terms of the agreement, Medivation will
receive an up-front cash payment of $110 million. Medivation is also eligible to receive payments of up to $335 million upon the attainment of development and regulatory milestones plus up to an additional $320 million in commercial milestone
payments. The companies will collaborate on a comprehensive development program that will include additional studies to develop MDV3100 for both late- and early-stage prostate cancer. Subject to receipt of regulatory approval, the companies will
jointly commercialize MDV3100 in the U.S. The companies will share equally all U.S. development costs, commercialization costs, and profits. Astellas will have responsibility for developing and commercializing MDV3100 outside the U.S. and will pay
Medivation tiered double-digit royalties on ex-U.S. sales. 
 “We are pleased to initiate a great partnership with Medivation,” stated Masafumi
Nogimori, president and chief executive officer of Astellas. “We believe that MDV3100 has the unique potential to establish a new treatment approach for prostate cancer. Astellas already has the global expertise in urology and the strong
commitment to focus on oncology. This partnership is a significant milestone to further expand our business in urology and to establish our franchise in oncology.” 

“We are excited to be working with Astellas to develop MDV3100 for a broad spectrum of prostate cancer disease states,” said David Hung, M.D.
president and chief executive officer of Medivation. “Astellas is an ideal partner for MDV3100 given its global reach, leading commercial presence in the urology space, and strategic focus on oncology. Astellas is the second major collaboration
we have completed in the past year, and we are confident we have the right partners in place for each of our late-stage programs—Astellas for MDV3100 and Pfizer, Inc for dimebon (latrepirdine*).”

Release– Page 1 








 According to the American Cancer Society, prostate cancer is the most common non-skin cancer among men in the
United States. More than 2 million American men have prostate cancer, and it is the second leading cause of cancer death among men after lung cancer. In 2009, an estimated 192,000 new cases are expected to be diagnosed, and approximately 27,000
men are expected to die from the disease. 
 MDV3100, a new generation of oral anti-androgen, which shows different pharmacological profiles from current
anti-androgens, has been shown in preclinical studies to provide more complete suppression of the androgen receptor pathway than bicalutamide, the most commonly used anti-androgen. MDV3100 slows growth and induces cell death in
bicalutamide-resistant cancers via three complementary actions—MDV3100 blocks testosterone binding to the androgen receptor, impedes movement of the androgen receptor to the nucleus of prostate cancer cells (nuclear translocation), and inhibits
binding to DNA. Preclinical data published in Science earlier this year demonstrated that MDV3100 is superior to bicalutamide in each of these three actions. 

The agreement is not subject to approval under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and becomes effective immediately. Medivation’s
legal and financial advisers on the transaction were Cooley Godward Kronish LLP and Aquilo Partners, L.P. Astellas’ legal adviser on the transaction was Covington & Burling LLP. 

 

	*	Latrepirdine is the proposed generic (nonproprietary) name for dimebon.

About MDV3100’s Clinical Program 
 In September 2009,
Medivation began enrolling patients in a randomized, placebo-controlled, double-blind, multi-national Phase 3 clinical trial known as AFFIRM. This trial is evaluating MDV3100 at a dose of 160 mg taken orally once daily versus placebo in men with
castration-resistant prostate cancer who were previously treated with docetaxel-based chemotherapy. The primary endpoint of the trial is overall survival; secondary endpoints include progression-free survival, safety and tolerability. This trial is
expected to enroll approximately 1,200 patients at sites in the United States, Canada, Europe, South America, Australia and South Africa. 
 Medivation
previously announced interim safety and efficacy results from an ongoing Phase 1-2 clinical trial of MDV3100. The interim results showed that MDV3100 was associated with anti-tumor activity in patients who had become resistant to bicalutamide or
other standard anti-androgen treatments, including both patients who had failed prior chemotherapy and patients who were chemotherapy naive. Anti-tumor activity was demonstrated by reductions in prostate-specific antigen levels, improvement or
stabilization in tumors that had spread to soft tissue or bone, and a decrease in circulating tumor cells, which has been associated in published literature with improved survival in patients with castration-resistant prostate cancer. MDV3100 was
generally well tolerated in this trial at doses up to and including 240 mg/day, with fatigue being the most frequently reported adverse event.
