a usage basis as clinical supplies are used, as the case may be, in each case via standard costs and reconciliation for variances to standard cost and inventory write-offs. In the event that a Party performs any of its manufacturing and supply
obligations through one or more Affiliates, any inter-company amounts or fees paid for any such services or Product or any intermediate used therein by such Party shall not be included in calculating Manufacturing Costs and only those costs directly
incurred by such Affiliate shall be so included.

For costs in subsection (a), Manufacturing Costs means: (i) the amount paid
to such a Third Party (excluding any Third Party Payments); plus (ii) the relevant manufacturing Partys reasonable direct and identifiable internal costs and out-of-pocket costs, incurred or accrued (including any prepayments) by the
manufacturing Party in connection with inventory write-offs, variances, manufacturing process improvements, storage, freight, manufacturing scale-up, manufacturing site qualification, materials, quality assurance and quality control (including
testing), supply chain management, capital equipment, similar activities comprising the manufacturing Partys oversight of the manufacturing process of the Third Party, and any value-added tax or similar tax due for amounts paid to such Third
Party, but excluding costs otherwise included within Development Costs.

For costs in subsection (b), Manufacturing Costs means the
standard cost per unit, including variances to standard costs and inventory write-offs. This standard cost shall include the cost of materials, labor, and other direct and identifiable variable costs incurred or accrued by the
manufacturing Party in connection with the manufacture of a Product, manufacturing process improvements, storage, freight, manufacturing scale-up, manufacturing site qualification, quality assurance and quality control (including testing), supply
chain management, and costs of equipment, plant operations and plant support services necessary to produce a Product, but excluding costs otherwise included within Development Costs. These costs of plant operations and support services shall include
utilities, maintenance, engineering, safety, human resources, finance, plant management and other similar activities, including idle plant capacity reserved specifically for the Product based on anticipated Product volumes in the ensuing [*] months.
Costs that cannot be identified to a specific activity supporting manufacturing of a Product, such as charges for corporate overhead or excess capacity not specifically reserved for the Product as described above, shall be excluded from the
determination of Manufacturing Costs.

Subject to the preceding paragraph, standard cost per unit for purposes of ongoing cost
accounting purposes shall be calculated in accordance with Partners then-current standard cost manual that is applied consistently to all pharmaceutical products sold by Partner. The Parties shall reconcile the standard cost charges, and
appropriate credits or payments from one Party to the other shall be made to effect such reconciliation not less than [*] against the above Manufacturing Cost definition.

Manufacturing Costs shall include costs of such activities that are undertaken at any time during the Term of this Agreement (including manufacturing activities relating to the Commercialization of a Product that are
undertaken prior to the initial Regulatory Approval of such Product).

Partys interest in the Collaboration at the price agreed upon by the Parties during the Negotiation Period.

(v)If, however, the other Party desires to purchase the Acquiring Partys interest in the Collaboration, but the Parties are unable to agree upon a price therefor during the Negotiation Period, then at the written election of either Party
within the [*]-Business Day period after the Negotiation Period, the Parties shall seek an outside valuation of such interest in the Collaboration and the price to be paid therefor, as set forth below, it being understood that such Third Party
Valuation Panels findings shall not be binding on either Party, but shall be available to guide the Parties continuing discussions, and shall provide a floor for any further negotiations of the price to be paid for such interest in the
Collaboration. Upon election by either Party to seek such an outside valuation, the Parties shall again engage in good faith negotiations for the sale of the Acquiring Partys interest in the Collaboration, for a period of [*] days following
receipt by the Parties of the findings of such Valuation Panel (the Second Negotiation Period).

(1)The
value of the Acquiring Partys interest in the Collaboration shall be determined by a panel of three (3) Third Party valuation experts (each, a Valuation Expert, and collectively, the Valuation
Panel). Each Valuation Expert shall be an [*] or [*], who shall not have had any [*] with either Party in the [*] prior to appointment, unless the Parties agree in writing to waive this requirement. Each Party shall select one
(1) such Valuation Expert, and such two (2) selected Valuation Experts shall jointly select a third Valuation Expert to serve as the Valuation Panel, provided, that no such third Valuation Expert may be a person to which either Party has a
reasonable objection communicated in writing to the other Party and to such two (2) other Valuation Experts not later than [*] Business Days following notice of such appointment. The Parties shall use their best efforts to cause the appointment
of the Valuation Panel to be completed within [*] days after the delivery of written notice by either Party that it desires to have the value of the interest in the Collaboration determined by the Valuation Panel.

(2)Each Party shall submit to the Valuation Panel and to the other Party prior
to any hearing, such information concerning the value of such Collaboration interest as such Party may deem appropriate together with such Partys last best offer to the other Party concerning the valuation of such interest.

[*] days prior written notice after the determination of the value of such interest and the price to be paid, but not earlier than the termination or expiration of any applicable waiting periods under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the HSR Act), and the receipt of all requisite approvals from Governmental Authorities, and, if the sale has been conditioned on the consummation of such Triggering Transaction, such
consummation having occurred. The Parties shall cooperate and shall promptly make such filings with and applications to such Governmental Authorities as may be required in connection with such purchase and sale.

(e)If a Party has notified the other Party in accordance with Section 7.9(b) or (c) that a Restricted Product will be
divested or if Partner notifies Medivation that it will terminate this Agreement in accordance with Section 7.9(b), the Commercialization of a Restricted Product by such Party during the period from the consummation of the applicable merger,
consolidation or acquisition to the consummation of such divestiture or sale or from the notice of such termination to the effective date of such termination shall not be considered a breach by such Party of its obligations under this Agreement;
provided, however, that such Party shall conduct any such Commercialization using personnel (i) distinct from personnel engaged in activities under this Agreement and (ii) who are not provided, directly or indirectly, or permitted to
access, any Confidential Information relating to Collaboration Molecules or Products.

8.5 Royalties.

(a) Licensed Territory. Partner shall pay to Medivation non-refundable, non-creditable royalties on the amount of Net Sales of each
Product in the Licensed Territory, as calculated by multiplying the applicable royalty rates set forth below by the corresponding amount of incremental Net Sales in the Licensed Territory of such Product in the Partner Year.



|                                                       |  |

|Net Sales in the Licensed Territory (Per Product)      |  | Royalty Rate
|Portion less than or equal to [*]                      |  | [*]         
|Portion greater than [*] and less than or equal to [*] |  | [*]

By way of example, if the aggregate Net Sales of a Product in the Licensed Territory in a particular Partner Year
is [*], the amount of royalties payable hereunder shall be as follows:

[*]

(b) Know-How Royalties.Notwithstanding Section 8.5(a), in any country in the Licensed Territory where, at the time of sale,
(x) there is neither (i) a Valid Claim of a Collaboration Patent that would be infringed, absent a license, by the manufacture, use or sale of a particular Product at the time of sale of such Product nor (ii) any Regulatory
Exclusivity with respect to such Product or (y) a Generic Product is being sold in such country, Partner shall owe royalties under Section 8.5(a) (as applicable to such country) on the Net Sales of such Product in such country at rates
that are [*] of the rates otherwise payable under such Section 8.5(a) for the remainder of the Royalty Term, such reduction to be prorated appropriately for the then-current Partner Quarter. The Parties agree and acknowledge that the payment of
royalties by Partner to Medivation for sales in a country in which there is no Valid Claim of a Collaboration Patent covering the applicable Product shall represent consideration for the license to Medivation Know-How granted by Medivation to
Partner in Section 7.1.

(c) Royalty Term. Royalties due under this Section 8.5 with respect to a
particular Product in a particular country in the Licensed Territory will commence upon the First Commercial Sale of such Product in such country and end on the date on which all of the following are true: (i) such Product is no longer covered
by a Valid Claim of a Collaboration Patent in such country, (ii) no Regulatory Exclusivity exists for such Product in such country, and (iii) a Generic Product is being sold in such country (such period, the Royalty
Term). Following the end of the Royalty Term, on a country-by-country and Product-by-Product basis, Partner shall have a royalty-free, perpetual, irrevocable, worldwide license, with the right to sublicense, to the Medivation Know-How
relating to such Product in such country.

(d) Backup Products. For any Backup Product, the royalty rates provided in
this Section 8.5 above shall be reduced by [*].

(e) Third Party Payments.Partner shall be entitled to deduct
from the royalties payable to Medivation based on Net Sales of a Product in the Licensed Territory, [*] of Approved Third Party Payments made with respect to Third Party Licenses for intellectual property of Third Parties which is necessary or
useful to make, have made, use, sell, offer for sale, import or export Collaboration Molecules or Product in the Licensed Territory, provided that with respect to such useful Third Party intellectual property, the Parties have agreed that a license
to such Third Party intellectual property should be obtained for use with Collaboration Molecules and Products in the Shared Territory and provided further, at no time shall the royalty rate otherwise payable to Medivation pursuant to
Section 8.5(a) (as those royalty rates may be reduced pursuant to Section 8.5(b)) be reduced by more than [*]. If, but for the proviso in the preceding sentence, the deduction under this Section 8.5(e) would have reduced a royalty
payment made by Partner by more than [*], then the amount of such deduction that exceeds [*] will be [*] to [*] until the [*].

(f) Royalty Payments and Reports.

(i)All royalty amounts payable to Medivation pursuant to this
Section 8.5 shall be paid in U.S. dollars within [*] days after the end of each Calendar Quarter with respect to Net Sales of each Product in the Licensed Territory in the corresponding Partner Quarter. Each payment of royalties due to
Medivation shall be accompanied by a statement, on a country-by-country basis, of the amount of Net Sales of each Product in Licensed Territory during the applicable Partner Quarter and a calculation of the amount of royalty payment due on such
sales for such Partner Quarter. Said reports shall be kept confidential by Medivation and not disclosed to any other party, other than Medivations accountants which shall be obligated to keep such information confidential, and such information
and reports shall only be used for purposes of this Agreement.

(ii) Inter-Company Sales. Sales between or among
Partner, its Affiliates or Sublicensees shall not be subject to royalties under Section 8.5. Partner shall be responsible for the payment of royalties on Net Sales by its Affiliates or Sublicensees to Third Parties.

8.6 Notices of Termination. In the event that Partner has given Medivation any notice of
termination of this Agreement under Article 13, no further payments under [*] shall become due following the date of such notice.

8.7
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 in accordance with applicable law to reduce value added tax or similar payments (VAT), Tax withholding and similar obligations on
royalties, milestone payments, and other payments made under this Agreement.

(c) VAT. In the event that any VAT is
owing in any jurisdiction in respect of any payment made by Partner to Medivation under this Agreement, then Partner shall pay such VAT, and (i) if such VAT is owing as a direct result of any action by Partner, including any assignment or
sublicense, or any failure on the part of Partner or its Affiliates to comply with applicable Tax laws or filing or record retention requirements, that has the effect of modifying the tax treatment of the Parties hereto, then the payment in respect
of which such VAT is owing shall be made without deduction for or on account of such VAT to ensure that Medivation receives a sum equal to the sum which it would have received had such VAT not been due or (ii) otherwise, such payment shall be
made after deduction of such VAT. Any increase in payments to Medivation under this Section 8.7(c) shall reflect only the incremental increase in VAT directly resulting from clause (i) above. In the event that any VAT is owing in any
jurisdiction in respect of any such payment, Medivation will provide to Partner tax invoices showing the correct amount of VAT in respect of such payments hereunder.

(d) Withholding Taxes. To the extent Partner is required to deduct and withhold Taxes from any payment to Medivation, Partner shall
pay the amounts of such Taxes to the proper Governmental Authority in a timely manner and promptly transmit to Medivation an official Tax receipt or other evidence of timely payment sufficient to enable Medivation to claim the payment of such Taxes
as a deduction or Tax credit. Medivation shall provide Partner any Tax forms that may be reasonably necessary in order for Partner to not withhold Tax or to withhold Tax at a reduced rate under an applicable bilateral income tax treaty and Partner
shall apply the reduced rate of withholding, or dispense with withholding, as the case may be, provided that Partner has received evidence, in a form satisfactory to Partner, of Medivations delivery of all applicable forms (and, if
necessary, its receipt of appropriate governmental authorization) at least [*] days prior to the time the applicable payment is due. Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by Applicable
Law, of withholding Taxes, value added Taxes, and 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.

(i) Taxes Resulting From Partner Action.If Partner is required to make a payment
to Medivation subject to a deduction or withholding of Tax, then (A) if such deduction or withholding of Tax obligation arises as a result of any action by Partner, including an assignment of this Agreement, or any failure on the part of
Partner to comply with Applicable Law, that has the effect of modifying the Tax treatment or increasing the Tax of Medivation (a Partner Withholding Tax Action), then subject to paragraph (ii) below, the payment by Partner
(in respect of which such deduction or withholding of Tax is required to be made) shall be increased by the amount necessary (the Additional Tax) to ensure that Medivation receives an amount equal to the amount that it would have
received had no such Partner Withholding Tax Action occurred, and (B) the Additional Tax shall be deducted and withheld by Partner from the payment made by Partner to Medivation. The Additional Tax, along with any other Tax deducted and
withheld from the payment made by Partner, shall be timely remitted to the proper Governmental Authority for the account of Medivation in accordance with Applicable Law.

(ii) Tax Credits and Tax Repayments. If any Additional Tax is paid pursuant to Section 8.7(d)(i) and Medivation determines
that it has derived full use and benefit from a credit against the payment of any Tax for all or any portion of such Additional Tax, or it receives a repayment of all or any portion of such Additional Tax, then Medivation shall, to the extent that
it can do so without prejudice to the retention of the amount of such credit or repayment, pay to Partner an amount that will leave Medivation (after such payment) in no worse after-Tax financial position than it would have been in had it not made
the payment to Partner.

(iii) Clawback of Tax Credits and Tax Repayments.If Medivation makes a payment to Partner
pursuant to Section 8.7(d)(ii) and Medivation subsequently determines that the credit or repayment in respect of which such payment was made was not available, or upon final settlement with an applicable Governmental Authority it is determined
that the credit or repayment in respect of which such payment was made was not available, Partner shall reimburse Medivation the amount that Medivation determines necessary to place Medivation in the same after-Tax financial position as it would
have been in had it not made the payment to Partner pursuant to Section 8.7(d)(ii).

8.8 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.

8.9 Foreign Exchange. Conversion of sales or expenses recorded in local currencies to U.S. dollars will be performed in a manner consistent with
each Partys normal practices used to prepare its audited financial statements for external reporting purposes, provided that such practices use a widely accepted source of published exchange rates.

8.10 Late Payments. Any amount required to be paid by a Party hereunder which is not paid on the date due but is paid on a date that is [*] days
or fewer past such date shall bear interest at a rate equal to the U.S. Prime Rate effective for the date payment was due, as reported by The Wall Street Journal, plus [*]. Any amount required to be paid by a Party hereunder which

is paid on a date that is [*] days or more past the date due shall bear interest at a rate equal to the U.S. Prime Rate effective for the date payment was
due, as reported by The Wall Street Journal, plus [*], computed for [*]. Such interest shall be computed on the basis of a year of 360 days for the actual number of days payment is delinquent.

8.11 Financial Records; Audits.Each Party shall maintain complete and accurate records in sufficient detail to permit the other Party to confirm
the accuracy of the amount to be reimbursed, pursuant to Section 8.2 with respect to Joint Development Costs, Joint Commercialization Costs or other amounts to be reimbursed or shared hereunder incurred or generated (as applicable) by such
Party, achievement of sales milestones, royalty payments and other compensation payable under this Agreement, as well as recording and tracking of Details to be provided in the Shared Territory. Upon reasonable prior notice, such records shall be
open during regular business hours for a period of [*] years from the date of rendering of the report to which the audit relates for examination at the auditing Partys expense, and not more often than once each Calendar Year, by an independent
certified public accountant selected by the auditing Party and reasonably acceptable to the audited Party for the sole purpose of verifying for the auditing Party the accuracy of the financial 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. The audited Party may require such accountant to enter into a reasonably acceptable
confidentiality agreement and 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. The opinion of said independent accountant regarding such reports and related payments shall be binding on the Parties, other than in the case of manifest
error. 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 8.10) from the
original due date (unless challenged in good faith by the audited Party in which case any dispute with respect thereto shall be resolved in accordance with Article 14). The auditing Party shall bear the full cost of such audit unless such audit
reveals an overpayment to, or an underpayment 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.

8.12 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 Partner (as applicable) at least five (5) Business Days
before such payment is due.

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 Partner, and such costs shall not
be included in Joint Development Costs or Joint Commercialization Costs. If Partner assumes responsibility for any Medivation Patents pursuant to clause (ii) above, then all costs incurred by Partner in the course of preparing, filing,

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. If Partner declines to file, or if either Party subsequent to filing determines that it is no longer interested in supporting the continued prosecution or maintenance of a particular Joint Patent in a country or
jurisdiction: (i) then the disclaiming Party shall provide the other Party 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 the
other Party with the opportunity to prepare, file, prosecute and maintain such Joint Patent; and (ii) the disclaiming Party shall, if requested in writing by the other Party, assign its ownership interest in such Joint Patent in such country or
jurisdiction to the other Party for no additional consideration (except in the case of a U.S. patent or patent application that is tied by a terminal disclaimer to another patent right owned by the disclaiming Party). If such assignment is effected
(or if it is not effected because of a terminal disclaimer), any such Joint Patent shall thereafter be deemed a Medivation Patent in the case of assignment to Medivation, or a Partner Patent that is not a Collaboration Patent in the case of
assignment to Partner; provided, however, that (x) in the case of an assignment to Partner, Medivation shall retain a non-exclusive, royalty-free perpetual license under such Joint Patent, subject to Partners exclusive right to exploit

the purpose of obtaining the extension in such country.

(e) Patents Licensed from Third Parties.Each Partys
rights under this Section 9.3 with respect to any Collaboration Patent or other Partner Patent licensed to a Party by a Third Party shall be subject to the rights of such Third Party to prosecute, maintain and extend such Collaboration Patent

Patents.

(a)If any Party receives notice by counterclaim, declaratory judgment action 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. Where such allegation is made in an opposition, reexamination,
interference or other patent office proceeding, the provisions of Section 9.3 shall apply. Where such allegation is made in a counterclaim to a suit or other action brought under Section 9.4, the provisions of Section 9.4 shall
apply. Where such allegation is made in a declaratory judgment or other court action, (i) the Party who prosecuted such Medivation Patent or Joint Patent pursuant to Section 9.3 shall have the first right to defend such action at its
own expense, provided that if a Party pursuant to Section 9.4 elects to bring an infringement counterclaim, the provisions of Section 9.4 shall thereafter apply; and (ii) Partner shall have the sole right, but no obligation, to defend
such Partner Patent. If the Party with the first right to defend a Medivation Patent or Joint Patent elects not to defend such action, it shall so notify the other Party in writing, and the other Party shall have the right to defend such action, at
the other Partys expense. For any such action involving a Collaboration Patent, the non-defending Party shall provide to the defending Party all reasonable assistance in such defense, at the defending Partys request and expense; and
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.

action that it defended under this Section 9.5 that admits the invalidity or unenforceability of any Collaboration Patent, requires abandonment or limits the scope of any Collaboration Patent or would limit or restrict the ability of either
Party to sell Products anywhere in the Territory.

Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Partys expense, in connection with the defense of the Claim for which indemnity is being sought. Subject to Section 9.6, the

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 11. Each Party shall provide the other with written evidence of such insurance prior to the Effective Date and upon
expiration of any one coverage. Partner and its Affiliates shall be an additional insured on Medivations products liability and clinical trials policies and be provided with a waiver of subrogation on each. Each Party shall provide the other

For clarity, any Information generated during or resulting from the Collaboration that is generated by a Party may be used by such Party for any purpose that does not violate Section 7.9 or Applicable Law, but the disclosure of such
Confidential Information shall be governed by this Article 12.

to any such disclosure;

(f)disclosure of the material terms of this Agreement to any bona fide potential or actual
investor, investment banker, acquirer, merger partner, or other potential or actual financial partner, with the prior written consent of the other Party not to be unreasonably withheld, and provided that in connection with such disclosure, each

Notwithstanding
the foregoing, in the event a Party is required to make a disclosure of the other Partys Confidential Information pursuant to Sections 12.2(a), 12.2(b), 12.2(c) or 12.2(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.

12.3 Publicity.

(a)The Parties agree that the terms of this Agreement are the Confidential Information of both Parties, subject to disclosure permitted by Section 12.2. The Parties have agreed to make a joint public announcement of the
execution of this Agreement the text of which is attached as Exhibit K, which shall be issued at a time to be mutually agreed by the Parties (but in any event no later than three (3) Business Days after such execution).

(b)After release of such press release, if either Party desires to make a public announcement concerning the terms of this
Agreement, such Party shall give reasonable prior advance notice of the proposed text of such 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 in the case of a press release, governmental filing or other public statement required (i) by Applicable Law or legal proceedings, (ii) to be contained in financial statements of the Parties prepared in accordance with
US GAAP, the disclosing Party shall (x) provide the other Party with sufficient advance notice of the text of such statement so that the other Party will have the opportunity to comment upon the statement, and the Party issuing such
statement shall give due consideration any such comments in the final statement and (y) in the case of any public statement that is required by Applicable Law or legal proceedings, use commercially reasonable efforts to obtain confidential
treatment of financial and trade secret information. A Party commenting on such a proposed press release shall provide its comments, if any, within five (5) Business Days after receiving the press release for review. In addition, where required
by Applicable Law of the applicable securities exchange upon which a party may be listed, a 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 the other Partys review of such an announcement, the other
Party may make specific, reasonable comments on such proposed press release within the prescribed time for commentary, but shall not withhold its consent to disclosure of the information that the relevant milestone or Regulatory Approval has been
achieved and triggered a payment hereunder. Neither Party shall be required to seek the permission of the other Party to repeat any information regarding the terms of this Agreement that has already been publicly disclosed by such Party, or by the
other Party, in accordance with this Section 12.3.

(c)The Parties acknowledge that either or both Parties may
be obligated 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 initially file a redacted copy of this Agreement approved by both Parties
(Redacted Agreement) and requests confidential treatment of the terms redacted from this Agreement for a reasonable period of time. In the event of any such filing, each Party shall (i) permit the other party to review and
comment upon such request for confidential treatment and any subsequent correspondence with respect thereto at least [*] in advance of its submission to the SEC or such other Governmental Authorities, (ii) reasonably consider and incorporate
the other Partys comments thereon to the extent consistent with the then-current legal requirements governing redaction of information from material agreements that must be publicly filed, (iii) promptly deliver to the other Party any
written correspondence received by it or its representatives from such Governmental Authority, if any, with respect to such confidential treatment request and promptly advise the other Party of any other communications between it or its
representatives with such Governmental Authority with respect to such confidential treatment request, (iv) upon the written request of the other Party, request an appropriate extension of the term of the confidential treatment period, where
available and (v) if such Governmental Authority requests any changes to the redactions set forth in the Redacted Agreement, use commercially reasonable efforts to support the redactions in the Redacted Agreement as originally filed (to the
extent consistent with the then-current legal requirements governing redaction of information from material agreements that must be publicly filed) and, to the extent reasonably practicable, not agree to any changes to the Redacted Agreement without
first discussing such changes with the other Party and taking the other Partys comments into consideration when deciding whether to agree to such changes. Each Party shall be responsible for its own legal and other external costs in connection
with any such filing, registration or notification.

12.4 Publications. Neither Party shall publicly present or publish results of
studies carried out under this Agreement (each such presentation or publication a Publication) without prior review and approval by the JCC (or its designated subcommittee) as set forth in Section 2.6(b)(vii)(5), except to
the extent otherwise required by Applicable Laws and consistent with Section 12.2.

13.2 Termination by Partner at Will. Partner shall have the right to terminate this Agreement in its entirety upon [*] days prior written notice to Medivation, provided, however, that Partner shall not have any
right to terminate the Agreement until eighteen (18) months following the First Commercial Sale of a Dimebon Product, unless prior to that date (a) there is clinical data for Dimebon that is [*] relative to the [*] as of the Effective Date
or (b) the Parties receive a Complete Response Letter from the FDA with respect to the Initial Dimebon Product or (c) (i) [*] or (ii) [*]. Any termination pursuant to clause (b) must be made no later than [*] days after a

(such decision by the JSC to be made within [*] following the completion of all reasonably necessary consultation and discussion with FDA or other applicable Regulatory Authority as to the need, scope and design of any additional Clinical Trials or
other activities that may be required as a result of such Complete Response Letter). During such [*] day notice period, Partner shall continue to perform all of its obligations under this Agreement, including performing all research, Development and

Development, and Commercialization of the Products during such [*] day period.

13.3 Termination by Either Party for Breach.

(a) Breach. Subject to Section 13.3(b), Medivation shall have the right to terminate this Agreement upon
written notice to Partner if Partner materially breaches its obligations under this Agreement and, after receiving written notice from Medivation identifying such material breach by Partner in reasonable detail, fails to cure such material breach
within ninety (90) days from the date of such notice (or within twenty (20) days from the date of such notice in the event such material breach is solely based upon Partners failure to pay any amounts due Medivation hereunder);
provided that such notice of termination is given within ten (10) days after the expiration of the ninety (90) day cure period. Subject to Section 13.3(b), Partner shall have the right to terminate this Agreement upon written notice

Promotion Product which is subject to Section 5.11(i)(i)) under this Agreement and, after receiving written notice from Partner identifying such
material breach by Medivation in reasonable detail, fails to cure such material breach within ninety (90) days from the date of such notice (or within twenty (20) 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 Partner hereunder); provided that such notice of termination is given within ten (10) days after the expiration of the ninety (90) day cure period.

(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 13.3(a), and such alleged breaching Party provides the other Party notice of such dispute and its intention to seek arbitration or judgment by a court pursuant to Article 14 within
such ninety (90) day period, then the non-breaching Party shall not have the right to terminate this Agreement under Section 13.3(a) unless and until an arbitrator or court, in accordance with Article 14, has determined that the alleged
breaching Party has materially breached the Agreement and that such Party fails to cure such breach within ninety (90) days following such decision of such arbitrator or court (except to the extent such breach involves the failure to make a
payment when due, which breach must be cured within twenty (20) days following such decision of such arbitrator or court). 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 and the Parties shall continue to perform all of their respective obligations hereunder.

13.4 Termination by
either Party due to Non-occurrence of Effective Date.Either Party shall have the right to terminate this Agreement, upon written notice to the other Party, if the Effective Date has not occurred by the date provided in and pursuant to
Section 10.6.

13.5 Effects of Termination of the Agreement.Upon termination of this Agreement by Partner under
Section 13.2 or by Medivation under Section 13.3, the following shall apply (in addition to any other rights and obligations under Section 13.2 or otherwise under this Agreement with respect to such termination):

(a) Licenses. Other than the license granted under Section 7.3, the licenses granted in Article 7 shall terminate.
Notwithstanding the foregoing, Partner hereby grants to Medivation, effective only upon such termination, a non-exclusive, worldwide, fully-paid, perpetual, irrevocable, royalty-free license, with the right to grant multiple tiers of sublicenses,
under the Reverted Partner Patents and Reverted Partner Know-How to research, Develop, make, have made, use, import, export, offer for sale, and sell any Products containing Dimebon or any other Collaboration Molecules that are in active clinical
development or are Commercialized as of the date of termination for the Field in the Territory and the provisions of Section 9.3(c) shall continue to apply in respect of Joint Patents, provided that if Medivation so requests in writing within
[*] days after the effective date of termination, Partner will grant to Medivation an exclusive worldwide license, with the right to grant multiple tiers of sublicenses, to research, Develop, make, have made, use, import, export, offer for sale, and
sell any Products containing Dimebon or any other Collaboration Molecules that are in active clinical development or are

Commercialized as of the effective date of termination for the Field in the Territory (i) under Reverted Partner Patents on Sole Inventions, upon
Medivations written agreement to pay all costs of prosecution and maintenance incurred after the effective date of termination, and (ii) under any other Reverted Partner Patents and Joint Patents, upon Medivations written agreement
to pay a reasonable royalty to be negotiated in good faith by the Parties. In all cases where any element of the Reverted Partner Know-How or the Reverted Partner Patents covered by this Section 13.5(a) is licensed to Partner by a Third Party,
as a condition precedent for a license to be granted to Medivation pursuant to this Section 13.5(a), Medivation shall be required to agree to pay any payments, including royalties on sales by Medivation or its Sublicensee, that accrue and
become payable to such Third Party licensor after the effective date of the license to Medivation. Partner will not be obligated to grant sublicenses under this Section 13.5(a), if Partner is prohibited from granting such sublicenses under its
agreement(s) with its licensor(s), but shall be required to use commercially reasonable efforts to obtain permission to grant such a sublicense from any such licensor(s).

(b) Marks. In the event notice of termination is provided after the date that is one (1) year prior to the anticipated First
Commercial Sale of a Product, Partner shall, as promptly as commercially practicable, assign to Medivation all right, title and interest in and to the Marks used or to be used with such Product (excluding any such Marks that include, in whole or
part, any corporate name or logo of Partner or its Affiliate or Sublicensee), including any goodwill associated therewith. For the avoidance of doubt, only those Marks which have been (i) identified as the single designated lead candidate
Mark for a non-commercialized Product, or (ii) actually used in connection with a Commercialized Product, shall be assigned. Medivation shall be responsible for recording such assignment in the Territory with the appropriate Governmental
Authority and will bear all costs associated with such assignment and recordation. Partner shall cooperate in facilitating such assignment and recordation by timely executing all necessary documents provided to it by Medivation.

(c) Regulatory Materials.Partner shall transfer and assign to Medivation in the form and format in which such materials are
maintained by Partner in the ordinary course of business, all Regulatory Materials for Products in the Territory that are Controlled by Partner or its Affiliates. Partner shall not be required to prepare any new data, reports or information solely
for purposes of transfer to Medivation and the Parties agree that any good faith failure by Partner to provide immaterial data, information, reports, records, correspondence or other materials to Medivation shall not be a breach of Partners
obligations under this Section 13.5(c).

(d) Transition Assistance. Partner shall, at no cost to Medivation,
provide reasonable consultation and assistance (Transition Assistance) for a period of no more than [*] after the effective date of termination for the purpose of transferring or transitioning to Medivation, (i) in the form
and format in which such Partner Know-How is maintained by Partner in the ordinary course of business, all Partner Know-How not already in Medivations possession, and (ii) at Medivations request, all then-existing Third Party
agreements relating solely to Collaboration Molecules and Products hereunder and that Partner is able, using reasonable commercial efforts to, assign to Medivation, in each case, to the extent reasonably

necessary for Medivation to continue researching, Developing, manufacturing, or Commercializing Products, provided, however, that Partner shall be required
to assign any such agreement solely to the extent assignment is permitted by such agreement, and Partner is not required to pay any consideration or commence litigation in order to effect an assignment of any such agreement to Medivation. If any
such agreement between Partner and a Third Party is not assignable to Medivation (whether by such agreements terms or because such agreement does not relate solely to Collaboration Molecules or Products) but is otherwise reasonably necessary
for Medivation to continue researching, Developing, manufacturing, or Commercializing Products, then Partner shall reasonably cooperate with Medivation to [*]. If Partner manufactures the Product itself (and thus there is no agreement to assign),
then Partner shall supply such bulk Collaboration Molecule or finished Product, as applicable, to Medivation, for a reasonable period (not to exceed [*] after the effective date of termination), pursuant to a supply agreement to be negotiated in
good faith by the Parties. Medivation shall reimburse Partner or any of Partners Third Party manufacturers for all reasonable out-of-pocket costs incurred pursuant to this Section 13.5(d).

(e) Remaining Inventories.Medivation shall have the right to purchase from Partner any or all of the inventory of Collaboration
Molecules and Products held by Partner as of the effective date of termination (that are not committed to be supplied to any Third Party or Sublicensee, in the ordinary course of business, as of the effective date of termination) (i) pursuant
to the terms of the supply agreement entered into under Section 13.5(d), or (ii) if the Parties do not enter into a supply agreement, at a price equal to [*]. Medivation shall notify Partner within [*] days after the effective date of
termination whether Medivation elects to exercise such right.

13.6 Medivations Material Breach.If Partner has the right to
terminate this Agreement under Section 13.3(a), then Partner may elect to (a) terminate this Agreement pursuant to Section 13.3(a) or (b) continue this Agreement by notice to Medivation provided, however, that if Partner elects
to continue this Agreement then (i) Partner shall retain the licenses granted under Section 7.1 and the license granted to Medivation pursuant to Section 7.2 (other than with respect to Co-Promoting a Co-Promotion Product under
Section 7.2(b)) shall terminate; (ii) all payment obligations set forth in Article 8 (including, without limitation, the Parties obligation to share Operating Profits and Operating Losses under Section 8.2) and Partners
diligence obligations under this Agreement (including without limitation Sections 3.3, 5.8(b), and 6.5) shall survive, (iii) all Committees shall be permanently disbanded and subject to Section 2.10, Partner shall have the sole right to
decide, without consultation, any matters previously before any such Committee or the Executive Officers, (iv) Medivation shall transfer and assign to Partner all Regulatory Materials for Products in the Shared Territory that are Controlled by
Medivation or its Affiliates; (v) Partner shall assume sole responsibility for all Development, Commercialization (other than Co-Promoting Co-Promotion Products pursuant to Sections 5.10 and 5.11), manufacturing, regulatory and all other
activities in the Shared Territory, and Medivations rights and obligations to Co-Promote all Products in the Shared Territory pursuant to Section 5.10 and 5.11 shall survive, (vi) Medivation rights and Partners obligations
pursuant to Sections 4.1(b)(i) and 4.1(c)(ii) (in each case with respect to Medivations right to

participate in regulatory activities and meetings) shall terminate and (vi) Medivation shall transfer or transition to Partner, upon Partners
request, all then-existing Third Party agreements relating solely to Collaboration Molecules and Products that Medivation is able, using reasonable commercial efforts, for Partner to commence or continue researching, Developing, manufacturing or
Commercializing Products, provided, however, that Medivation shall be required to assign any such agreement solely to the extent assignment is permitted by such agreement, and Medivation is not required to pay any consideration or commence
litigation in order to effect an assignment of any such agreement to Partner. In the event that Partner makes any election as provided in this Section 13.6, the Parties will enter into an appropriate and customary written amendment reflecting
such changes. If Partner elects to terminate this Agreement pursuant to Section 13.3(a), the provisions of Section 9.3(c) shall continue to apply in respect of Joint Patents. For the avoidance of doubt, Partner shall be entitled, in its
sole discretion, to make the elections provided for in this Section 13.6 upon each occurrence of a material uncured breach by Medivation.

13.7 Other Remedies. Except as provided in Sections 8.6 and 13.2, 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.

13.8 Rights in Bankruptcy.All rights and licenses granted under or pursuant to this Agreement by Medivation and Partner 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 of a bankruptcy proceeding by or against a
Party (such Party, the Bankrupt Party) under the U.S. Bankruptcy Code, (a) 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 (x) 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 (y) if not delivered under clause (x), following the rejection of this Agreement by the Bankrupt Party upon written
request therefor by the other Party and (b) the Bankrupt Party shall not interfere with the other Partys rights to intellectual property and all embodiments of intellectual property, and shall assist and not interfere with the other Party
in obtaining intellectual property and all embodiments of intellectual property from another entity. The embodiments of intellectual property includes all tangible, intangible, electronic or other embodiments of rights and licenses
hereunder, including all compounds and products embodying intellectual property, Products, filings with Regulatory Authorities and related rights and Medivation Know-How in the case that Medivation is the Bankrupt Party and Partner Know-How in the

DISPUTE
RESOLUTION

14.1 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 that may arise under any theory of law 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 14.2. 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.

14.2 Arbitration. Any dispute, controversy, difference or claim that may arise under any theory of law between the Parties and not from a Committee, out of or in relation to or in connection with this Agreement (including, without

claim or controversy under Section 14.10, shall be settled by [*] as follows. Either Party, following the end of the [*] period referenced in
Section 14.1, 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, and shall have some experience in mediating or arbitrating issues relating to such agreements. If the Parties cannot agree on such arbitrator within [*] days of request by a Party for arbitration, then such arbitrator shall
be appointed by the American Arbitration Association, which arbitrator must meet the foregoing criteria. Within [*] days after an arbitrator is selected (or appointed, as the case may be), each Party will deliver to both the arbitrator and the other
Party a detailed written proposal setting forth its proposed terms for the resolution for the matter at issue (the Proposed Termsof the Party) and a memorandum (the Support Memorandum) in support thereof, not
exceeding [*] pages in length. The Parties will also provide the arbitrator a copy of this Agreement, as may be amended at such time. Within [*] days after receipt of the other Partys Proposed Terms and Support Memorandum, each Party may
submit to the arbitrator (with a copy to the other Party) a response to the other Partys Support Memorandum, such response not exceeding [*] pages in length. Neither Party may have any other communications (either written or oral) with the
arbitrator other than for the sole purpose of engaging the arbitrator or as expressly permitted in this Section 14.2; provided that, the arbitrator may convene a hearing if the arbitrator so chooses to ask questions of the Parties and hear oral
argument and discussion regarding each Partys Proposed Terms. Within [*] days after the arbitrators appointment, the arbitrator will [*]. The decision of the arbitrator shall be final, binding, and unappealable. For clarity, [*].

14.3 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.

14.4 Award. Any award to be paid by one Party to the other Party as determined by the arbitrator as set forth above under Section 14.2 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 14, and agrees that, subject to the United States 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. With respect to money damages, nothing contained herein shall be construed to permit the arbitrator or any court or any other forum to award consequential, incidental,
special, punitive or exemplary damages. By entering into this agreement to arbitrate, the Parties expressly waive any claim for consequential, incidental, special, punitive or exemplary damages. The only damages recoverable under this Agreement are
direct compensatory damages.

14.5 Costs. Each Party shall bear its own legal fees. The arbitrator shall assess his or her
costs, fees and expenses against the Party losing the arbitration.

14.6Injunctive Relief. Nothing in this Article 14 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. For the avoidance of doubt, nothing in this Section 14.6 shall otherwise limit a
breaching Partys opportunity to cure a material breach as permitted in accordance with Section 13.3.

14.7 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.

14.8 Survivability. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after termination of this Agreement for any reason.

14.9 Jurisdiction. For the purposes of this Article 14, the Parties acknowledge their diversity (Partner having its principal place of business in
the State of New York and Medivation having its principal place of business in the State of California) and agree to accept the jurisdiction of any U.S. District Court located in California for the purposes of enforcing any awards entered pursuant
to this Article 14 and for enforcing the agreements reflected in this Article 14.

14.10 Patent and Trademark Disputes.
Notwithstanding Section 14.2, 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.

ARTICLE 15

MISCELLANEOUS

15.1 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, as of the Effective Date, all prior agreements and understandings between the Parties with respect to the subject matter hereof, including, without limitation, the Existing Confidentiality Agreement. 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 Agreement. In the event of any inconsistency
between any plan hereunder (including the Joint Development Plan and/or Shared Territory Commercialization 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.

15.2 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. 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.

15.3 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 15.3, 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.

15.4 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.

15.5 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 all or substantially all of the business of such Party, 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) or a Third Party is acquired by Partner (such
Third Party, hereinafter referred to as a (Target), then (x) the intellectual property of such Acquiror held, owned, controlled or developed by such Acquiror (whether prior to or after such acquisition) shall be excluded from
Medivation Technology (in the case when the acquired Party is Medivation) and Partner Technology (in the case when the acquired Party is Partner), and (y) the intellectual property of such Target held, owned, controlled or developed by such
Target (whether prior to or after such acquisition) shall be excluded from Partner Technology and such Acquiror or Target, as the case may be (and Affiliates of such Acquiror or Target, as the case may be, which are not controlled by (as defined in
Article 1) the acquired Party itself or Partner, in the case of a Target) shall not be deemed an Affiliate solely for purposes of the applicable components of the foregoing intellectual property definitions, in all such cases if and only
if: (a) [*]; (b) [*]; and (c) [*]. For clarity, in the event that a Party is acquired by an Acquiror or Partner acquires a Target and any of the criteria described in subclauses (a) through (c) is not satisfied, then the
intellectual property of such Acquiror or Target shall be included within Medivation Technology (in the case when the acquired Party is Medivation) and Partner Technology (in the case when the acquired Party is Partner or Partner has acquired
Target), and licensed as provided hereunder, but only to the extent such intellectual property of such Acquiror or Target is legally able to be so licensed pursuant to applicable Third Party licenses, provided however that a Party shall be required
to license such intellectual property as long as it is not required to pay any consideration or commence litigation in order to effect such license. 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 15.5 (but not the criteria set forth in subclauses (a) through (c)) shall be null, void and of no legal effect.

15.6 Standstill.

(a) Partner agrees that upon the Effective Date and for a period lasting until the earlier of the [*] of the [*] for the [*] in the [*] to have such [*] and [*] after the [*] (the Standstill Period), neither
Partner nor any of its Affiliates shall, in any manner, directly or indirectly without the prior written consent or invitation of Medivation or its Board of Directors:

(i)make, effect, initiate, cause or participate in any acquisition of beneficial
ownership of any voting securities of Medivation or any voting securities of any subsidiary of Medivation, if the effect of such acquisition would be to entitle Partner to cast directly or indirectly more than [*] of the voting power in any election
of directors of Medivation. For purposes of the [*] calculation under this Section 15.6, all such voting securities, rights or options beneficially owned by Partner (including through Affiliates or others) shall be treated on an as-exercised
and as-converted basis, but such securities, rights or options beneficially owned by others shall not be so treated;

(ii)make, effect, initiate, cause or participate in any acquisition of any material assets of Medivation or any material assets of any subsidiary of Medivation that would place Medivation or Partner under a legal obligation to make
a public disclosure of such activity;

(iii)engage or become a participant in any solicitation of
(x) proxies (as such terms are defined in Regulation 14A under the Exchange Act) or (y) consents to vote any Medivation voting securities;

(iv)form, join or participate in a group (as defined in the Exchange Act) for the purpose of taking any action
under clauses (i) through (iii) of this Section;

(v)agree or offer to take, or encourage or propose
(publicly or otherwise) the taking of any action referred to in subsection (i), (ii), (iii), or (iv) of this Section 15.6(a);

(vi)assist, induce or encourage any other person to take any action of the type referred to in subsection (i), (ii), (iii), (iv), or (v) of this Section 15.6(a);

(vii)enter into any discussions, negotiations, arrangement or agreement with any other person relating to any of the foregoing;

(b)Nothing in this Section 15.6 shall preclude Partner from making proposals on a confidential basis, to
Medivation or its Board of Directors, or from seeking a waiver from Medivation of any provision set forth in this Section 15.6, on a confidential basis, and provided such proposal or waiver is not designed to, nor could reasonably be required
to, result in public disclosure of such proposal or waiver by either Partner or Medivation. In addition, Medivation agrees that it shall notify Partner within [*] days of its having received a written proposal or term sheet from a Third Party with

PFIZER AND MEDIVATION ENTER INTO GLOBAL AGREEMENT TO CO-DEVELOP AND

MARKET DIMEBON FOR THE TREATMENT OF ALZHEIMERS AND HUNTINGTONS

DISEASES

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

NEW YORK, NY and SAN FRANCISCO, CA, September 3  Pfizer Inc (NYSE: PFE) and Medivation, Inc.(NASDAQ: MDVN)
announced today that they have entered into an agreement to develop and commercialize Dimebon, Medivations investigational drug for treatment of Alzheimers disease and Huntingtons disease. Dimebon currently is being evaluated in an
international, confirmatory Phase III trial in patients with mild-to-moderate Alzheimers disease (www.connectionstudy.com).

Under the terms
of the agreement, Medivation will receive an up-front cash payment of $225 million. Medivation also is eligible to receive payments of up to $500 million upon the attainment of development and regulatory milestones plus additional undisclosed
commercial milestone payments. Medivation and Pfizer will collaborate on the Phase III program in Alzheimers disease, Huntingtons disease development and regulatory filings in the United States. The companies will share all U.S.
development and commercialization expenses along with U.S. profits/losses on a 60 percent/40 percent basis, with Pfizer assuming the larger share of both expenses and profit/losses. In addition, Medivation will co-promote Dimebon to specialty
physicians in the U.S.

Pfizer will have responsibility for development, regulatory and commercialization outside the U.S. and will pay Medivation
royalties on commercial sales outside of the U.S. The agreement is subject to approval under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. J.P. Morgan served as financial advisor, and Cooley Godward Kronish LLP served as legal advisor,
to Medivation on this transaction.

Alzheimers disease leads to the death of brain cells and the loss of nerve connections in areas of the brain that
govern memory, thinking and behavior. Alzheimers disease gradually destroys a persons memory and ability to learn, reason, make judgments, communicate and carry-out daily activities. No currently marketed Alzheimers disease drug
appears to stop brain cell death and prevent or restore lost nerve connections.

Dimebon is an orally-available, small molecule that has been shown to
inhibit brain cell death in preclinical models relevant to Alzheimers disease and Huntingtons disease, making it a potential treatment for these and other neurodegenerative conditions. Based on preclinical data generated to date, Dimebon
appears to improve the function of mitochondria, the energy generators in cells that play a vital role in governing brain cell health, growth and overall function. Dimebon also has been shown to stimulate the outgrowth of nerves from brain
cells, or neurites, a process that is believed to play an important role in restoring or generating new brain cell connections.

With more than
18 million people worldwide suffering from the debilitating and ultimately fatal effects of Alzheimers disease, Pfizer has made this devastating illness one of our highest priorities, said Dr. Martin Mackay, president, Pfizer
Global Research and Development. We are working to develop new medicines that improve memory and halt or significantly slow the diseases progression. We look forward to collaborating with Medivation to bring Dimebon to patients as
rapidly as possible.

After a rigorous process that garnered substantial interest, we believe that Pfizer is the ideal partner, sharing our
vision for Dimebon and capable of maximizing its potential globally, said Dr. David Hung, president and chief executive officer of Medivation. As one of the leaders in Alzheimers disease, Pfizer is an optimal partner because
of its extensive experience developing new medicines; its marketing and commercialization track record; and, its significant global capability to effectively reach primary care physicians, who today prescribe the vast majority of Alzheimers
disease medications in the U.S.

About Dimebons Clinical Program

Results from the first pivotal trial of Dimebon in Alzheimers disease showed that patients treated with Dimebon experienced statistically significant improvements compared to placebo in key aspects of the
disease  memory and thinking, activities of daily living, behavior and overall function. Dimebons benefit over placebo continued to increase throughout the 12-month treatment period. At the end of 12 months, Dimebon-treated patients were
on average functioning as well or better than they had been at the start of the study on each of 5 clinical endpoints. These results were published in the July 19, 2008 issue of The Lancet,and are noteworthy as untreated
Alzheimers patients progressively deteriorate over time in these areas.

On July 7, 2008, Medivation announced positive safety and
efficacy results from its Phase 2 trial of Dimebon in Huntingtons disease, which was conducted in collaboration with the Huntington Study Group. Dimebon appeared to be well tolerated and showed statistically significant benefit versus placebo
in cognition as measured by the Mini-Mental State Examination, a secondary endpoint in the study.
