Bayer shall have the right between the [**] and [**] anniversary of the Effective Date to request the inclusion of a [**] Collaboration Target under this Agreement on the same general terms as provided for the original [**] Collaboration Targets, subject to mutual written agreement of the Parties, such agreement to not be unreasonably withheld or delayed.  In connection with any such request, Bayer shall have the right to nominate and reserve a [**] Collaboration Target (subject to the acceptance criteria set forth in Section 2.2.1), provided that work on such target shall commence within [**] following reservation of such target, and if such work does not commence at such time through no fault of Arvinas, such reservation shall thereafter be of no further force or effect unless otherwise agreed by Arvinas in writing.  For the avoidance of doubt, to the extent applicable, payments for the [**] Collaboration Target shall not exceed the pro rata share of the agreed payments for the first [**] Collaboration Targets, including, for clarity, an upfront fee of [**] the amount due pursuant to Section 5.1.

2.2.4

The Parties agree that no more than one Collaboration Target will be [**] target, provided that any permitted replacement target, as described above, may be [**] target.  The Parties shall agree in good faith on whether or not a target is [**] target. The Parties also agree, that targets primarily related to [**], for example, targets expressed in [**], targets present in [**], and targets associated with [**], are not regarded as [**] targets.

2.2.5

If, as of the completion of activities under the Pre-Exploratory Stage (as defined in the Generic Research Plan) for a given Collaboration Target, Arvinas has been unable to identify any Collaboration Compounds directed to such Collaboration Target that meet the relevant criteria specified in the relevant Research Plan, as determined and agreed by the JSC, Bayer shall have the right, [**] for each of the original Collaboration Targets, to nominate a new target as a replacement for that Collaboration Target, which nomination shall be made within [**] of such JSC determination by written notice to Arvinas (a “Target Replacement Notice”).  Arvinas shall notify Bayer in writing within [**] after delivery of the Target Replacement Notice if the proposed replacement Collaboration Target is an Excluded Target, in which event Bayer shall without undue delay nominate an alternate replacement Collaboration Target.  If the proposed replacement is not an Excluded Target, Arvinas shall so notify Bayer in writing within [**] after delivery of the Target Replacement Notice, and such proposed replacement Collaboration Target shall be deemed accepted by Arvinas at such time.  Provided that the proposed replacement Collaboration Target is accepted as provided above, such replacement Collaboration Target shall become a Collaboration Target for all purposes under this Agreement and the replaced initial Collaboration Target shall cease to be a Collaboration Target for all purposes under this Agreement, and the relevant License under Section 3.1.1 shall terminate.  The Parties shall agree on the Research Plan for such replacement Collaboration Target in accordance with Section 2.1 promptly following issuance of the relevant Target Replacement Notice.

2.3

Conduct of Research Program; Funding; Research Term. During the Research Term, Arvinas and Bayer shall each use Commercially Reasonable Efforts to complete their respective activities, and in accordance with any relevant timelines, as set out in the Research Plans, and shall use personnel with sufficient skills and experience as are required to accomplish the Research Program in accordance with the terms of this Agreement and each Research Plan.  

2.3.1

The Research Program will be conducted during the period from the Effective Date of the Collaboration Agreement until the completion or termination of all research activities to be performed under the relevant Research Plans (“Research Term”), provided that the Research Plan with respect to a given Collaboration Target will aim at identifying a Collaboration Compound that satisfies the Lead Compound Criteria [**] within a period of [**] unless otherwise agreed by the Parties.  The JSC shall have the responsibility for determining whether the Research Program with respect to a given Collaboration Target has been completed, provided that, in the absence of any such determination and unless otherwise agreed by the Parties in writing, for each Collaboration Target for which activities have been commenced under the Research Program, if no research funding is allocated in accordance with this Section 2.3 to such Collaboration Target for any Research Program Year after relevant Research Program activities have commenced, the Research Program with respect to the relevant Collaboration Target shall be deemed completed as of the end of the last Research Program Year for which funding was allocated. Notwithstanding any other provision, the Research Term shall not exceed [**], and the Research Program shall terminate at such time with respect to all Collaboration Targets, unless otherwise agreed by the Parties in writing, such agreement to not be unreasonably withheld.

2.3.2

In consideration for the conduct of the Research Program, Bayer shall pay to Arvinas research funding payments totaling US$3,000,000 (in words: three million US dollars) per year in each of the first four (4) Research Program Years following the Effective Date, plus any additional amounts agreed by the Parties in writing. Payment shall be made to Arvinas as provided in Section 5.2.  This consideration shall cover all costs at Arvinas for its work under the Research Program for the ongoing Research Plans, including, without limitation, any administration costs at Arvinas, all employee-related compensation, travel costs and all resources and consumables used for activities under the Research Program to be performed by Arvinas, which shall be incurred in accordance with the applicable Research Plan (including Budget) and this Agreement. Subject to the funding limits set forth above, for each Collaboration Target for which work is to be conducted under the Research Program, as part of the relevant Research Plan, the Parties shall agree on the Budget for the various research activities under such Research Plan, based on the applicable FTE Rates. [**].  For clarity, the Parties may agree in writing to conduct additional activities as part of the Research Program beyond those specified in the initial Research Plans (e.g., development of Collaboration Compounds meeting Preclinical Candidate criteria), but any such activities shall require additional funding and mutual written agreement on modifications to the relevant Research Plan and Budget.  

2.3.3

If costs borne by Arvinas for its research activities under the ongoing Research Plans exceed the research funding amount specified in Section 2.3.2 for a given Research Program Year (“Cap”) before completion of all relevant Research Program activities for the respective Research Program Year, including as a result of any permitted replacement of a Collaboration Target in accordance with Section 2.2.5, and Arvinas has complied with its reporting obligations under Sections 2.3.6 and 2.3.7, Arvinas shall not be obligated to carry out further Research Program activities under this Agreement for the given Research

Program Year unless Bayer has agreed in writing to fund such additional activities, including any additional FTEs required to carry out such additional work.  For clarity, in the event that funds are exhausted during a Research Program Year as described above, funding for continued activities may be provided under the funding for the subsequent Research Program Year (in which event activities will not be resumed until the start of such subsequent Research Program Year), or through the provision of additional funding for the current Research Program Year, as mutually agreed by the Parties in writing, in each case subject to corresponding mutually agreed adjustments of the ongoing Research Plan(s). If such Cap is, after completion of the research activities for the respective Research Program Year, not reached, then Arvinas shall credit the remainder against the funding amount for Research Program activities to be conducted in the following Research Program Year, if any.

2.3.4

Bayer shall be entitled to utilize the services of its Affiliates or Third Parties to perform its Research Program activities.  Arvinas shall be entitled to utilize the services of Affiliates or Third Parties to perform its Research Program activities only upon Bayer’s prior written consent or as specifically set forth in the relevant Research Plan; provided that, as of the Effective Date, Bayer has consented to Arvinas subcontracting with [**] to conduct services with respect to the Research Program by and on behalf of Arvinas.  Notwithstanding any of the foregoing, (a) any such subcontracted activities shall be subject to the relevant terms and conditions of this Agreement; (b) each Party shall enter into agreements with its Third Party subcontractors that contain confidentiality terms no less stringent than those set forth in Article 4 hereof and shall ensure that it obtains all rights to the subcontracted works that are necessary to comply with the intellectual property and licensing provisions of this Agreement; and (c) each Party shall remain at all times fully liable for its respective responsibilities under the Research Program and its obligations under this Agreement.

2.3.5

Except as otherwise expressly provided in this Agreement, each Party shall be responsible for all costs and expenses it incurs relating to such aspects of the Research Program as are to be provided or performed by that Party according to each Research Plan, as amended in accordance with this Agreement.    

2.3.6

Within [**] after the end of each Calendar Quarter (or portion thereof) that occurs during the Research Term, including the Calendar Quarter in which it begins or ends as applicable, Arvinas shall provide Bayer with a reasonably detailed report concerning the FTE costs actually incurred during such Calendar Quarter for the Research Program, identified by Collaboration Target, and of reimbursable expenses incurred in accordance with the relevant Research Plan and Budget (“Actual Costs”). Such reporting may be provided more frequently as mutually agreed by the Parties.  [**].  Bayer shall have the right to review and audit the Research Program FTE Records [**], following written notice to Arvinas and at mutually agreeable times, provided that more frequent audits may be conducted by Bayer at mutually agreeable times in the event of cause (e.g., material discrepancies).

2.3.7

In the event of any unanticipated issue that may, in Arvinas’ reasonable opinion, result in research costs exceeding the Cap in a given Research Program Year, Arvinas shall promptly notify the JSC about such issue and the anticipated increased costs and the Parties shall convene a meeting of the JSC to discuss a solution to the matter as soon as reasonably practicable.

2.4

Governance.  

2.4.1

General.  Bayer and Arvinas shall form a joint steering committee (the “Joint Steering Committee” or “JSC”) to oversee the conduct of the Research Program. The JSC shall be responsible for oversight of the Research Program, and for reviewing and approving recommendations, plans, allocation of resources and other activities in support of the Research Program, and implementing the Research Plan(s), with the objective of expeditiously identifying Collaboration Compounds for each Collaboration Target meeting the desired criteria. The JSC shall be responsible for the monitoring, reviewing and reporting on the progress of the Research Program.  

2.4.2

Composition of the JSC. The JSC shall be comprised of [**] representatives of Bayer and [**] representatives of Arvinas.  Each Party may change its representatives to the JSC from time to time in its sole discretion, effective upon notice to the other Party of such change.  These representatives shall have appropriate technical credentials, experience and knowledge, and ongoing familiarity with the Research Program.  Additional representative(s) or consultant(s) may from time to time, by mutual consent of the Parties, be invited to attend JSC meetings, subject to such representative’s or consultant’s written agreement to comply with the requirements of Article 4 and consistent with Section 7.1.6.  The JSC shall be chaired by a representative of Bayer.  Each Party shall bear its own expenses related to attendance at such meetings by its representatives.  Following the end of the Research Term, the JSC shall have a final meeting to review the results of the Research Program and then shall be disbanded. As needed, the JSC shall establish subcommittees and other working groups that shall report to the JSC, having equivalent functional counterparts from each Party, to further the objectives of the Research Program.

2.4.3

Decision Making.  Decisions of the JSC shall be made unanimously by the Parties with each Party having one vote.  In the event that the JSC cannot or does not, after good faith efforts, reach agreement on an issue related to the Research Program (excluding issues for which the JSC expressly does not have decision-making authority), the resolution or course of conduct shall be determined by Bayer following referral to the senior executives of the Parties as provided in Section 10.7.  In exercising its final decision-making authority with respect to JSC decisions as described above, Bayer shall act in accordance with the objectives of the Research Program and the terms of this Agreement, and in good faith.  Notwithstanding the foregoing, Bayer’s decision-making authority under this Section 2.4.3 does not give Bayer the right to modify a Research Plan in any way that would require Arvinas to commit additional resources (e.g., employees, materials, reagents) to the project without Arvinas’ consent, that would be inconsistent with the scope of the relevant existing, mutually agreed Research Plan, cause Arvinas to violate the terms of any agreement with a Third Party, or cause Arvinas to violate any applicable Law or any intellectual property right of any Third Party.  However, Arvinas shall not unreasonably withhold or delay its consent to requests by Bayer to shift resources between the Research Plans in order to reprioritize the activities, as long as the overall budget is not exceeded. For clarity, the JSC shall have no right to amend this Agreement.

2.4.4

Meetings.  During the Research Term, the JSC shall meet in accordance with a schedule established by mutual written agreement of the Parties, but no less frequently than [**] times per Calendar Year, with the location for such meetings alternating between Arvinas and Bayer facilities (or such other location(s) as may be determined by the JSC).  Alternatively, the JSC may meet by means of teleconference, videoconference or other similar communications equipment.  The JSC shall confer regarding the status of the Research Program, review relevant data, consider and advise on any technical issues that arise, consider issues of priority, and review and advise on any budgetary and economic matters relating to the Research Program which may be referred to the JSC.

2.4.5

Alliance Managers.  In addition to the JSC, each Party shall appoint, at its own cost and expense, an alliance manager (each, an “Alliance Manager”) with responsibility for assisting the Joint Steering Committee to achieve the alliance’s strategic and research objectives by, as further defined by the JSC, planning and managing the operational aspects of the alliance, ensuring alliance effectiveness and appropriate communications, coordinating activities, anticipating issues, and facilitating conflict resolution.

2.4.6

Project Managers.  In addition to the foregoing, each Party shall nominate a project leader for each Research Plan who shall be responsible for the day-to-day dealings under the respective Research Plan and shall be the first contact person for the other Party for operational and scientific matters with regard to such activities (each a “Project Leader”). Each Project Leader shall:

(a)

ensure that its Party’s research activities are performed in accordance with the applicable Research Plan;

(b)

inform the other Party’s Project Leader on the progress of the project (including any expected or experienced difficulties, obstacles or delays) on a regular basis, however, at least bi-weekly, by means of teleconference, videoconference or other mutually agreed means;

(c)

internally coordinate its project team;

(d)

give progress reports to the JSC during the JSC meetings and propose to the JSC, as necessary, amendments to the applicable Research Plan; and

(e)

with respect to Arvinas’ Project Leader, ensure the timely submission and accurate preparation of the progress reports as set forth in Section 2.6.3 and - if applicable - the Research Plan.

2.5

Exchange of Information.  Arvinas shall promptly disclose to Bayer, upon reasonable written request of Bayer, all Licensed IP and other Collaboration IP necessary for the performance of the Research Program by Bayer, or for the subsequent exercise of the License with respect to any Collaboration Target in accordance with Section 3.1. Bayer shall promptly disclose to Arvinas during the Research Term, upon reasonable written request of Arvinas or as directed by the JSC, all results of the Research Program generated by Bayer or its permitted subcontractors, and all Bayer Technology and other Bayer Know-How necessary for the performance of the Research Program by Arvinas.  However, Arvinas shall only disclose to Bayer, as Arvinas Confidential Information, Technology specifically related to [**], and such information only to the extent that it is [**]. Arvinas shall only disclose to Bayer [**] if Bayer [**]. For clarity, the [**] shall be deemed Confidential Information of [**], provided that, for clarity, the [**] that is contained therein shall remain [**] Confidential Information.  Arvinas shall use [**] to ensure that [**] shall not be disclosed by Arvinas to Bayer except as [**] and Arvinas shall ensure that [**] shall not be disclosed by Arvinas to Bayer.  Notwithstanding the foregoing, Arvinas shall use [**] to provide information required for [**], including the [**], to the extent requested by Bayer and [**].

2.6

Records and Reports.

2.6.1

Such reports shall be provided in accordance with any relevant requirements of Section 2.5.  

2.7

Materials Transfer.  In order to facilitate the Research Program, either Party may provide to the other Party certain materials for use by the other Party in furtherance of the Research Program.  Neither Party may furnish any such materials to the other Party except as expressly provided in the applicable Research Plan or this Agreement without the prior written consent of the other Party.  All such materials shall be considered the Confidential Information of the Party providing such material (provided that if they are a combination of the proprietary materials of both Parties, they shall be deemed the Confidential Information of both Parties) and shall be used by the receiving Party in accordance with the terms and conditions of this Agreement solely for purposes of exercising its rights and performing its obligations under this Agreement.  All such materials must be used with prudence and appropriate caution in any experimental work, since all of their characteristics may not be known, and in compliance with all applicable Laws and any relevant Third Party contractual requirements that have been communicated in writing to the receiving Party.  Such transfer shall not be deemed a transfer of any intellectual property rights with respect to such material.  Any and all compounds, biological materials, reagents, assays and other materials that are provided by one Party to the other Party hereunder in furtherance of the Research Program activities and that are not consumed in the course of performance of such activities, shall all be returned to the providing Party promptly upon the completion of the Research Program, or, if the providing Party so instructs in writing, or if such material exists in the form of a combination of the proprietary materials of both Parties, all such materials shall be destroyed and the destruction of such materials shall be certified in writing, in accordance with written instructions to be provided by the providing Party upon completion of the Research Program; provided, however, that such obligation shall not apply to the extent rights to the relevant materials or information are obtained or retained by either Party pursuant to the express provisions of this Agreement. For clarity and without limitation, any Deliverables that are provided to Bayer for purposes of performing evaluation or testing during the Research Program shall be subject to this Section 2.7, and (i) unless and until Bayer has the right to practice the relevant License pursuant to Section 3.1.5, shall only be used by Bayer for performing the relevant agreed assays or other permitted activities and Bayer agrees not to analyze or reverse engineer any such material for the purpose of determining the structure thereof, and (ii) the results of any such activities conducted by or on behalf of Bayer using Deliverables shall be subject to the provisions of Article 7.

2.8

Exclusive Efforts.  During the term of this Agreement, for each Reserved Target and for each Collaboration Target, and excluding the activities being conducted under the Research Program, Arvinas and its Affiliates will neither directly nor indirectly (including on behalf of a Third Party),

(i) conduct or agree to conduct any activities with respect to the design, identification, discovery or development of any small molecule pharmacologically-active agent whose primary mechanism of action is, by design, directed to inhibition or degradation of such Reserved Target or Collaboration Target, or (ii) grant any license or covenant not to ▇▇▇ or other right to any third party in the Field under the Licensed IP that is intended to enable such Third Party with respect to the conduct of any such activities, provided that, for clarity, retention by a Third Party (whether through a non-exclusive license or otherwise) of rights with respect to technology invented by such Third Party with respect to which rights are obtained by Arvinas in the relevant transaction (whether through assignment or license or other right to Arvinas) shall not be deemed to violate this subsection (ii). Notwithstanding the foregoing, in the event that a Person that becomes an Arvinas Affiliate through a Change of Control or through acquisition of “control” (as defined in the definition of Affiliate) by Arvinas (a “Transaction”), has a program underway, at the time that Arvinas first enters into the Transaction, with respect to the design, identification, discovery or development of any small molecule pharmacologically-active agent whose primary mechanism of action is, by design, directed to inhibition or degradation of any Reserved Target or Collaboration Target, such activity may continue following the effective date of the Transaction, provided that (i) such program is conducted by individuals who have (and have had) no involvement in Research Program activities directed to the relevant Collaboration Target and no direct knowledge of or access to the Bayer Know-How or Collaboration IP related to such Collaboration Target and/or related Collaboration Compounds, and (ii) such program does not utilize any Licensed IP.

2.9

Compliance with Law and Ethical Business Practices.  Each Party shall conduct the activities of the Research Program and its other activities under this Agreement in accordance with all applicable Laws and good business ethics.  Each Party shall notify the other Party in writing of any deviations from applicable Laws relevant to this Agreement of which any of its employees becomes aware.  Each Party hereby certifies that it has not and shall not employ or otherwise use in any capacity the services of any person or entity debarred under Section 21 USC 335a in performing any activities hereunder.  Each Party shall notify the other Party in writing immediately if any such debarment relevant to this Agreement occurs or comes to its attention, and shall promptly remove any person or entity so disbarred from performing any activity or function related to the Research Program.  Bayer shall have the right, in its sole discretion, to terminate this Agreement immediately in the event of any such debarment, which termination shall be deemed a termination for cause.

2.10

Use of Human Materials.  If any human cell lines, tissue, human clinical isolates or similar human-derived materials (“Human Materials”) have been or are to be collected or used in the Research Program by a Party or any Affiliate or Third Party acting on such Party’s behalf, such Party represents and warrants (i) that it has complied, or shall comply, with all applicable Laws relating to the collection or use of the Human Materials and (ii) that it has obtained, or shall obtain, all necessary approvals and - if required - appropriate informed consents, in writing, for the collection or use of such Human Materials, including – if applicable – the transfer to the other Party. Each Party shall provide documentation of such approvals and/or consents to the other Party upon the other Party’s reasonable request.  Each Party further represents and warrants that any such Human Materials that are used in the Research Program may be used as contemplated in this Agreement without any obligations to the individuals or entities (“Providers”) who contributed the Human Materials, including any obligations of compensation to such Providers or any other Third Party for the intellectual property associated with, or commercial use of, the Human Materials for any purpose.

2.11

Animal Research.  Each Party shall comply with the Animal Welfare Act or any other applicable Laws relating to the care and use of laboratory animals in connection with its activities under this Agreement.  Each Party is encouraged to use the highest standards, such as those set forth in the Guide for the Care and Use of Laboratory Animals (NRC, 1996), for the humane handling, care and treatment of such research animals.  Arvinas hereby certifies that, prior to conducting any animal research at any facility in connection with the Research Program, it shall obtain accreditation from AAALAC and shall maintain such accreditation for so long as it conducts such research and Bayer hereby certifies that any animal research conducted at Bayer’s facilities in connection with the Research Program shall be in accordance with all relevant local animal welfare regulations. Any animals which are used by or on behalf of either Party in the course of the Research Program, or products derived from those animals, such as eggs or milk, will not be used for food purposes, nor will these animals be used for commercial breeding purposes.  

3.1

Licenses; Rights.

3.1.1

4.8

Publicity/Use of Names.  Neither Party shall use the name, trademark, trade name or logo of the other Party, its Affiliates or their respective employee(s) in any publicity, promotion, news release or disclosure relating to this Agreement or its subject matter, without the prior express written permission of the other Party, except for those disclosures expressly authorized under this Article 4 or as permitted with respect to the trademark “PROTAC®” under Section 3.1.6.

Royalties Payable by Bayer.  Subject to the terms and conditions of this Agreement, Bayer shall pay Arvinas royalties, calculated on a Product-by-Product basis, as set forth in this Section 5.4.       

(a)

Patent Royalties.  Bayer shall pay Arvinas royalties in an amount equal to the applicable percentage of Net Sales of the relevant Product by Bayer or its Related Parties in the applicable Calendar Year of the applicable Royalty Period as stated below, provided that the sale of such Product is Covered by a Valid Patent Claim in the country of sale:

(i)

[**] percent ([**]%) of Net Sales in the Territory in each Calendar Year up to and including [**] US Dollars (US$[**]);

(ii)

[**] percent ([**]%) of Net Sales in the Territory in each Calendar Year for the portion of Net Sales exceeding [**] US Dollars (US$[**]) up to and including [**] US Dollars (US$[**]);

(iii)

[**] percent ([**]%) of Net Sales in the Territory in each Calendar Year for the portion of Net Sales exceeding [**] US Dollars (US$[**]) up to and including [**] US Dollars (US$[**]); and

(iv)

[**] percent ([**]%) of Net Sales in the Territory in each Calendar Year for the portion of Net Sales exceeding [**] US Dollars (US$[**]).

(b)

Know-How Royalty.  In countries in which the sale of the relevant Product by Bayer or its Related Parties is not Covered by a Valid Patent Claim in the country of sale, Bayer shall pay Arvinas royalties as a percentage of Net Sales of the relevant Product by Bayer or its Related Parties in the applicable Calendar Year of the applicable Royalty Period at royalty rates that shall be set at [**] percent ([**]%) of the royalty rate applicable at the relevant time determined according to 5.4.1(a)(i)  through (iv).  

(c)

Royalty Period.  For clarity, royalty tiers pursuant to Section 5.4.1(a) and (b) shall be calculated based on aggregate Net Sales of each Product in the applicable Calendar Year of the applicable Royalty Period.  Royalties on each Product at the rates set forth above shall continue on a country-by-country basis until the expiration of the later of: (i) the last-to-expire Valid Patent Claim that Covers the manufacture, use or sale of the relevant Product; or (ii) a period of ten (10) years after First Commercial Sale of such Product in such country (the “Royalty Period”).  Upon expiration of the Royalty Period with respect to any Product in any country, subject to fulfillment of all relevant royalty and milestone payment obligations hereunder, Bayer shall have a fully paid-up, perpetual and irrevocable right to continue to make, use and sell such Product in such country. For the avoidance of doubt, any relevant License in any country and for any Product shall survive the expiration of the relevant Royalty Period, unless otherwise terminated in accordance with this Agreement, and any such expiration of a Royalty Period shall not limit Bayer’s right to continue to Develop and Commercialize the relevant Product in the relevant country under any continuing License.

(d)

Conditions.  All royalties are subject to the following conditions:

(i)

that only one royalty shall be due with respect to each unit of Product sold, regardless of the number of Valid Patent Claims Covering such Product;

(ii)

that no royalties shall be due upon the sale or other transfer among Bayer or its Related Parties, but in such cases the royalty shall be due and calculated upon Bayer’s or its Related Party’s Net Sales to the first independent Third Party;

(iii)

no royalties shall accrue on the sale or other disposition of Products by Bayer or its Related Parties for use in a Clinical Trial; and

(iv)

no royalties shall accrue on the disposition of Products by Bayer or its Related Parties as samples (promotion or otherwise) or as donations (for example, to non-profit institutions or government agencies for a non-commercial purpose).

5.4.2

Royalty Reductions.

(a)

Compulsory Licenses.  If a compulsory license is required to be granted by Bayer to a Third Party with respect to any Product in any country in the Territory with a royalty rate payable to Bayer with respect to sales of such Product that is lower than the effective royalty rate for such Product provided by Section 5.4.1, after application of any permitted credits or reductions pursuant to Section 5.4.2(b) or 5.4.2(c), then the royalty rate to be paid by Bayer on Net Sales in that country under Section 5.4.1 with respect to such Product shall be reduced to the rate paid by the compulsory licensee to Bayer with respect to such Product.

(b)

Third Party Licenses.  

(i)

In the event that one or more patent licenses from other Third Parties are required, or reasonably deemed necessary or useful, in each case as determined by Bayer or its Related Parties in their sole discretion, and are obtained by Bayer or its Related Parties in order to use or practice PROTAC Background IP or PROTAC Improvement IP in order to Develop, Manufacture, Commercialize, use or otherwise exploit any Collaboration Compound or Product under a License as permitted hereunder (hereinafter “Third Party Patent Licenses”), [**] percent ([**]%) of the consideration actually paid under such Third Party Patent Licenses by Bayer or its Related Parties with respect to such Collaboration Compound or Product in a country with respect to any Calendar Quarter shall be creditable against the royalty payments due to Arvinas from Bayer hereunder with respect to the sale of such Collaboration Compound or Product in such country with respect to such Calendar Quarter; provided, however, that in no event shall the rate of the royalties payable by Bayer to Arvinas in accordance with Section 5.4.1 with respect to the sale of Collaboration Compound or Product in a particular country be reduced pursuant to this Section 5.4.2(b) below [**] percent ([**]%) of the amount otherwise payable under Section 5.4.1(a) or Section 5.4.1(b), as applicable (and for clarity without the application of any permitted reduction pursuant to Section 5.4.2(c)).

(ii)

In the event that the Yale Agreement is terminated, and thereafter, notwithstanding such termination, Bayer retains its sublicense hereunder to the Yale Licensed Patents granted pursuant to Section 3.1.1 or enters into a direct license agreement with Yale for such continued right, Bayer shall have the right to credit [**] percent ([**]%) of the royalty payments actually paid by Bayer or its Related Parties to Yale during a certain Calendar Quarter in connection with Bayer’s or such Related Party’s Development, Manufacture, Commercialization, use or other exploitation of any Collaboration Compound or Product under a License as permitted hereunder against the royalty payments due to Arvinas during such same Calendar Quarter under Section 5.4.1(a) or Section 5.4.1(b), as applicable.

(c)

Market Entry of a Generic Version. Upon the first commercial sale of a Generic Version of a Product in a particular country in the Territory during the applicable Royalty Period, the following shall apply:  if the aggregate unit sales of all Generic Version(s) in such country over a period of [**] (“Market Share Period”) exceed [**] percent ([**]%) of the sum total unit sales of such Product and all Generic Version(s) (i.e., based on unit volume market share) in such country during such Market Share Period, then beginning in the first [**] after such Market Share Period, Bayer shall have the right to reduce any royalties payable in such country under Section 5.4.1 above by [**] percent ([**]%). Such unit sales volume will be based on data from IMS Health or another data service acceptable to both Parties.  As necessary, appropriate payment adjustments or true-ups shall be made in the case, for example, where there is a delay in the availability of the applicable IMS Health or other volume data.

(d)

Limits.  Notwithstanding any other provision of this Agreement, in no event shall the rate of the royalties payable by Bayer to Arvinas in accordance with this Agreement with respect to the sale of any Collaboration Compound or Product in a particular country during the Royalty Period be reduced below [**] percent ([**]%).

5.5

No Adjustment for Arvinas Third Party Agreements.

5.6

Reports; Payment of Royalty.  During the term of this Agreement following the First Commercial Sale of a Product, Bayer shall furnish to Arvinas a quarterly written report for each Calendar Quarter showing, by Product and by country, the Net Sales of each Product subject to royalty payments sold by Bayer and its Related Parties in the Territory during the reporting period and the royalties payable under this Agreement.  Reports shall be due on the [**] following the end of each Calendar Quarter.  Royalties shown to have accrued by each royalty report shall be due and payable within [**] after Bayer’s receipt of an invoice from Arvinas.  Reports of any relevant withholding taxes shall be made in accordance with Section 5.11.

5.7

Invoicing; Method of Payment. Invoices must include the appropriate Bayer Purchase Order (PO) number (if provided by Bayer to Arvinas), reference to this Agreement and type of payment due, itemized description of work completed if applicable, amount owed, and name and address to which the payment is to be sent as well as such other information as may be reasonably required by Bayer.

Audits.

5.8.1

Bayer shall keep, and shall require its Related Parties to keep, complete and accurate records in sufficient detail to enable the amounts payable hereunder to be determined. Upon [**] written request of Arvinas and not more than [**] and [**] for each reporting period, Bayer and its Related Parties shall permit an internationally recognized independent certified public accounting firm or chartered accountant selected by Arvinas and reasonably acceptable to Bayer, at Arvinas’ expense, to have access during normal business hours to such of the records of Bayer and its Related Parties as may be reasonably necessary to verify the accuracy of the reports and notices under this Article 5 for any Calendar Year ending not more than [**] prior to the date of such request.  The accounting firm shall disclose to Arvinas only whether the reports are correct or incorrect, and whether any milestone event notifications have not been properly made, and the amount of any discrepancy.  No other information shall be provided to Arvinas.

5.8.2

If such accounting firm correctly identifies a discrepancy made during such period, Bayer shall pay to Arvinas the amount of any underpayment discrepancy, plus any interest due as set forth in Section 5.13, within [**] of the date Arvinas delivers to Bayer such accounting firm’s written report so correctly concluding, or as otherwise agreed upon by the Parties.  The fees charged by such accounting firm shall be paid by Arvinas; provided, however, that if such audit uncovers an underpayment of royalties by Bayer that exceeds [**] percent ([**]%) of the total royalties owed for the relevant period, then the fees of such accounting firm shall be paid by Bayer. If such accounting firm concludes that Bayer overpaid royalties to Arvinas, then Arvinas shall refund such overpayments to Bayer, within [**] of the date Arvinas receives such accountant’s report or, if such overpayment is more than [**] US dollars, then Arvinas and Bayer shall mutually agree on mechanism for such refund, which mechanism may include a credit against any future payment by Bayer to Arvinas or a repayment schedule.

5.8.3

Bayer shall include, or cause to be included, in each sublicense granted pursuant to this Agreement a provision requiring the relevant Related Party to make reports to Bayer, to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records by Arvinas’ independent accountant to the same extent required of Bayer under this Agreement.

5.8.4

Arvinas shall treat all financial information subject to review under this Section 5.8 or under any relevant sublicense agreement in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with Bayer or its Related Parties obligating it to retain all such information in confidence pursuant to such confidentiality agreement.

5.9

Payment Exchange Rate.  All payments to be made by Bayer to Arvinas under this Agreement shall be made in United States dollars and may be paid by check made to the order of Arvinas or bank wire transfer in immediately available funds to such bank account in the United States as may be designated in writing by Arvinas from time to time.  In the case of sales outside the United States, the rate of exchange to be used in computing the monthly amount of currency equivalent in United States dollars due Arvinas shall be made at the monthly rate of exchange utilized by Bayer in its worldwide accounting system.

5.10

Value Added Tax. All agreed remuneration under this Agreement is considered to be net of value added tax (“VAT”). VAT shall apply additionally to the extent legally owed; payable by Bayer after receipt of a proper invoice which meets all legal requirements according to the applicable VAT laws.  

5.11

Withholding Taxes. Arvinas shall be liable for any and all taxes, duties and other levies applied by a government of any country of the Territory on payments made by Bayer to Arvinas under this Agreement. In the event that any payments due to Arvinas are subject to withholding tax required by applicable Law to be paid to the taxing authority of any foreign country, Bayer may deduct the amount of such tax from the applicable payment otherwise payable to Arvinas. Any such withheld tax shall be treated as having been paid by Bayer to Arvinas for all purposes of this Agreement. In such event, Bayer shall, on a timely basis, notify Arvinas of such obligation, pay the taxes to the proper taxing authority and send evidence of the obligation together with proof of payment thereof to Arvinas following that payment. Each Party agrees to cooperate with the other Party in claiming exemptions from such deductions or withholdings under any relevant agreement or treaty which is in effect. In the event that Bayer cannot deduct the withholding tax due to any mutually agreed fulfilment of a Bayer payment obligation by settlement or by set-off, Arvinas shall pay the withholding tax to Bayer separately. If Bayer failed to deduct withholding tax but is still required by tax law to pay withholding tax on account of Arvinas to the tax authorities, Arvinas shall reasonably assist Bayer with regard to all procedures required in order to obtain reimbursement by tax authorities or, in the event that the tax authorities will not reimburse the withholding tax to Bayer, Arvinas shall promptly refund the tax amount.

5.12

Blocked Currency. If by applicable Law or fiscal policy of a particular country, conversion into United States dollars or transfer of funds of a convertible currency to the United States is restricted or forbidden, royalties accrued in that country shall be paid to Arvinas in the country in local currency by deposit in a local bank designated by Arvinas, unless the Parties otherwise agree in writing.

5.13

Interest Due. Any payments due under this Agreement shall be due on such date as specified in this Agreement. Any failure by Bayer to make a payment within [**] after the date when due shall obligate Bayer to pay interest on the due payment to Arvinas. The interest period shall commence on the due date (inclusive) and end on the payment date (exclusive). Interest shall be calculated based on the actual number of days in the interest period divided by 360. The interest rate per annum shall be equal to the [**], or shall be equal to the [**], whatever is lower. In case the [**] as agreed by the Parties shall be used instead.

6.1

[**], it is the sole and exclusive owner or licensee (from its licensor) of the Licensed IP, all of which are (and shall be, in the case of Arvinas Collaboration IP and Arvinas’ rights in Joint Collaboration IP) free and clear of any liens, charges and encumbrances, except for liens, charges and encumbrances imposed under that certain (a) Loan Agreement by Connecticut Innovations, Incorporated (“CII”) and Arvinas dated as of August 20, 2013 and that certain Security Agreement between CII and Arvinas dated as of August 20, 2013 that was entered into in connection with such Loan Agreement, and (b) Assistance Agreement by and between the State of Connecticut acting by the Department of Economic and Community Development (the “DECD”) and Arvinas dated January 24, 2014 and that certain Security Agreement by and between Arvinas and the DECD dated as of January 24, 2014 that was entered into in connection with such Assistance Agreement;

6.2.7

[**], the practice by Arvinas of the Licensed IP (and for clarity not in conjunction with any specified target) in the performance of the Research Program will not interfere with or infringe any intellectual property rights owned or possessed by any Third Party;

6.2.8

[**], the exercise of the licenses granted to Bayer under the Licensed IP, including the Development, Manufacture, use, and Commercialization of Collaboration Compounds and Products, will not interfere with or infringe any intellectual property rights owned or possessed by any Third Party; and

6.2.9

there are no (a) claims, demands, suits, proceedings, arbitrations, inquiries, investigations or other legal actions of any nature, civil, criminal, regulatory or otherwise, pending or to the best knowledge of Arvinas, threatened against Arvinas or (b) judgments or settlements against or owed by Arvinas, for (a) and (b), relating to the Licensed IP.

7.1

Inventorship and Ownership. The Parties agree that the United States federal patent law on inventorship shall determine the inventorship of any invention and the names of the inventors on any patent filings, whether sole or joint inventions, which arise in connection with activities conducted pursuant to this Agreement.  

7.1.1

PROTAC Background IP.  Arvinas shall own (or control through licenses from Third Parties) all PROTAC Background IP, even if used to support the aims of the Research Program (e.g., generation of new Connectors).  Nothing in this Agreement shall be deemed to ▇▇▇▇▇ ▇▇▇▇▇ any rights to own, use or access any PROTAC Background IP or other Patent Rights or other Technology of Arvinas other than as expressly provided in this Agreement.

7.1.2

Bayer Technology.  Bayer shall own (or control through licenses from Third Parties) all Bayer Technology and, subject to the provisions of this Agreement regarding Collaboration Compound IP, all other Technology of Bayer, whether existing as of the Effective Date or identified or developed during the term of this Agreement or thereafter, made or developed independently by Bayer outside the scope of the Research Program, even if used to support the aims of the Research Program, with the exception of any PROTAC Improvement IP developed by Bayer in the course of the research or development of one or more Collaboration Compounds or Products in the Territory in accordance with the licenses granted under this Agreement that is to be owned by Arvinas as provided in Section 7.1.4 and that, for clarity, is not Sole Bayer PROTAC Improvement IP (with respect to which rights of the Parties shall be governed by Sections 7.1.4(b) and (c)).  Nothing in this Agreement shall be deemed to grant Arvinas any rights to own, use or access any Bayer Technology or other Patent Rights or other Technology of Bayer other than as expressly provided in this Agreement.

7.1.3

Bayer Compounds. With respect to Bayer Compounds within Bayer Technology and other Bayer Compounds that are derivatives, modifications or improvements thereof made by or on behalf of either Party in the course of performance of the Research Program (including any such Bayer Compound used as or contained or incorporated into a Targeting Compound, but excluding any Connector or Ligand contained in any such derivative, modification or improvement), Bayer shall own all right, title and interest in and to such Bayer Compounds, provided that, notwithstanding such Bayer ownership, with respect to any derivative of, modification of or improvement to any Bayer Compound that is made solely or jointly by Arvinas in the course of performance of the Research Program, Bayer shall not have the right to make, use or sell any such Bayer Compound in connection with the Development or Commercialization of any pharmacologically-active agent whose primary mechanism of action is, by design, directed to any target other than a Collaboration Target, unless otherwise agreed in writing by Arvinas, such agreement to not be unreasonably withheld. Arvinas agrees that it will not withhold its agreement if it is not, by contractual obligations with Third Parties, legally prevented from providing its consent. Nothing in this Agreement shall be deemed to grant Arvinas any rights to own, use or access any Bayer Compounds or related Patent Rights other than as expressly provided herein.

7.1.4

PROTAC Improvement IP.  Subject to Section 7.1.4(b) and to Section 7.2.5, Arvinas shall solely own all PROTAC Improvement IP and shall own all Patent Rights filed thereon.  Nothing in this Agreement shall be deemed to ▇▇▇▇▇ ▇▇▇▇▇ any rights to own, use or access any PROTAC Improvement IP or related Patent Rights other than as expressly provided in this Agreement.  

(a)

Arvinas’ rights to PROTAC Improvement IP shall be subject to Sections 2.8, 7.1.4(c) and 7.2.5, and any licenses expressly granted to Bayer pursuant to Article 3.  

(b)

Any PROTAC Improvement IP invented solely by Bayer or its Affiliates or a Third Party acting on behalf of Bayer or its Affiliates (“Sole Bayer PROTAC Improvement IP”) shall remain owned by Bayer, subject to a non-exclusive, worldwide, perpetual, fully paid license to Arvinas, which for clarity shall be subject to the limitations set forth in Section 7.1.4(c). Bayer shall be solely responsible for all payments to inventors of Sole Bayer PROTAC Improvement IP, including payments under inventorship compensation laws, that may arise in

connection with such license to Arvinas. Notwithstanding Bayer’s sole ownership of Sole Bayer PROTAC Improvement IP, Bayer agrees (i) that it shall have no right to sublicense Sole Bayer PROTAC Improvement IP except in connection with a license of rights to a related Bayer product, including for the avoidance of doubt, for the joint research, development, manufacture and commercialization of a Bayer product in collaboration with a Third Party, and (ii) that Patent Rights shall be filed on Sole Bayer PROTAC Improvement IP solely as provided in Section 7.2.2.

(c)

Notwithstanding Arvinas’ sole ownership of PROTAC Improvement IP that is not Sole Bayer PROTAC Improvement IP as provided above, and the non-exclusive license to Arvinas granted in Section 7.1.4(b), Arvinas may utilize PROTAC Improvement IP, including Sole Bayer PROTAC Improvement IP, only for Arvinas’ internal programs or for programs conducted by or on behalf of Third Parties who license Arvinas’ protein degradation technology or related products, but not with respect to any Collaboration Target that is included under a License granted to Bayer under this Agreement that is in effect at the relevant time.

(d)

For clarity, any ownership by Arvinas of PROTAC Improvement IP shall not include or imply any rights to use any underlying Technology of Bayer, and any ownership by Bayer of Sole Bayer PROTAC Improvement IP shall not include or imply any rights to use any underlying Technology of Arvinas.

7.1.5

Collaboration IP and Collaboration Compound IP.   The entire right, title and interest in:

(a)

Arvinas Collaboration IP shall be owned solely by Arvinas;

(b)

Bayer Collaboration IP shall be owned solely by Bayer;

(c)

Joint Collaboration IP shall be owned jointly by Arvinas and Bayer; provided that, subject to any Licenses granted to Bayer under this Agreement, and except for use in connection with performance of the Research Program, neither Party shall have the right to use or practice Joint Collaboration IP, or to grant licenses under its interest in Joint Collaboration IP or corresponding Joint Patent Rights (to be filed solely as provided in Section 7.2.4(b)), without the written consent of the other Party, such consent to not be unreasonably withheld or delayed; and

(d)

Collaboration Compound IP shall be owned solely by Bayer; provided that neither Party shall have any rights to use, practice or license any Collaboration Compound, Product, Collaboration Compound IP or Collaboration Compound Patent Rights other than in the course of performance of the Research Program or pursuant to a License granted under this Agreement or as otherwise expressly agreed by the Parties in writing. For clarity, Arvinas shall retain all right, title and interest in and to each Connector and each Ligand contained in any Collaboration Compound that is transferred to Bayer by Arvinas (the “Arvinas Components”), in part as to Arvinas Components that exist in combination with other material, and any transfer of Arvinas Components to Bayer under this Agreement shall be a bailment and shall not constitute a sale of Arvinas Components or a grant, option or license of any patent or other rights controlled by Arvinas, other than a license to Bayer to use the Arvinas Components in the practice of a license expressly granted under this Agreement. For the avoidance of doubt and unless expressly agreed otherwise

in this Agreement, to the extent the Collaboration Compound IP incorporates any portion of the Bayer Technology, Bayer Collaboration IP or Sole Bayer PROTAC Improvement IP (the “Bayer Components”), Bayer shall retain the right to use any of these Bayer Components for any purposes and in connection with any target.

7.1.6

Employee/Representative Assignments.  Each Party shall maintain valid and enforceable agreements obligating all employees or representatives performing activities under or contemplated by this Agreement, to assign his/her interest in any invention conceived or reduced to practice in the course of such activities to the Party for which such employee or representative is providing his/her services. Each Party agrees to execute such documents, render such assistance, and take such other action as the other Party may reasonably request, to apply for, register, perfect, confirm, and protect the other Party’s rights in any Technology arising in the course of performance of this Agreement to be owned by the other Party pursuant to this Section 7.1.  For clarity, Bayer shall be solely responsible for all payments to inventors of any Licensed IP or Collaboration Compound IP who are employees or representatives of Bayer or its Affiliates, or of a Third Party acting on behalf of Bayer or its Affiliates, that may arise in connection with any permitted use or license of any such Licensed IP or Collaboration Compound IP under this Agreement and Arvinas shall be solely responsible for all payments to inventors of any Licensed IP or Collaboration Compound IP who are employees or representatives of Arvinas or its Affiliates, or of a Third Party acting on behalf of Arvinas or its Affiliates, that may arise in connection with any permitted use or license of any such Licensed IP or Collaboration Compound IP under this Agreement.

7.2

Disclosure; Prosecution and Maintenance of Patents.  

7.2.1

Disclosure.  Subject to compliance with Section 2.5, Arvinas shall promptly disclose to Bayer in writing the development, conception or reduction to practice of inventions within the Collaboration Compound IP, Arvinas Collaboration IP, PROTAC Improvement IP, and Joint Collaboration IP.  Bayer shall promptly disclose to Arvinas in writing the development, conception or reduction to practice of inventions within Joint Collaboration IP and PROTAC Improvement IP and, to the extent arising in the course of performance of the Research Program, Collaboration Compound IP.  Patent Rights on any inventions within Collaboration IP, PROTAC Improvement IP and Collaboration Compound IP shall be Prosecuted and Maintained solely in accordance with this Article 7.  

7.2.2

Prosecution and Maintenance of Patent Rights claiming PROTAC Background IP and PROTAC Improvement IP.  As between Bayer and Arvinas, Arvinas shall be responsible for the Prosecution and Maintenance of Patent Rights claiming PROTAC Background IP or PROTAC Improvement IP, and Arvinas shall be responsible for all costs incurred by Arvinas with respect to such Prosecution and Maintenance.  Arvinas shall appropriately consult with Bayer with respect to any such Prosecution or Maintenance to the extent relevant to Collaboration Compounds or Products exclusively licensed to Bayer under this Agreement. Notwithstanding the foregoing, no Patent Rights shall be filed on Sole Bayer PROTAC Improvement IP without mutual written agreement of the Parties, which written agreement shall address and govern ownership of and rights to Prosecute and Maintain and enforce such Patent Rights.

7.2.3

Prosecution and Maintenance of Patent Rights claiming Collaboration Compound IP.  Subject to Section 3.1.4, as between Bayer and Arvinas, Bayer shall own and be responsible for the Prosecution and Maintenance of Patent Rights claiming Collaboration Compound IP (“Collaboration Compound Patent Rights”), and Bayer shall be responsible for all costs incurred by Bayer with respect to such Prosecution and Maintenance.  Bayer shall appropriately consult with Arvinas with respect to any such Prosecution or Maintenance to the extent relevant to existing or potential patent filings on PROTAC Background IP or PROTAC Improvement IP.

7.2.4

Filing, Prosecution and Maintenance of Patent Rights claiming Other Collaboration IP.  

(a)

Arvinas Collaboration IP.  Arvinas shall be responsible for the Prosecution  and Maintenance of Patent Rights claiming Arvinas Collaboration IP (“Arvinas Program Patent Rights”), and Arvinas shall be responsible for all costs incurred by Arvinas with respect to such Prosecution and Maintenance.  Arvinas shall appropriately consult with Bayer with respect to any such Prosecution or Maintenance to the extent relevant to Collaboration Compounds or Products exclusively licensed to Bayer under this Agreement. If Arvinas elects not to file Patent Rights on any Arvinas Collaboration IP in any country in the Territory, or elects to Prosecute or Maintain such Arvinas Program Patent Rights in some but not all countries in the Territory, Arvinas shall notify Bayer and Bayer shall have the right to Prosecute or Maintain such Arvinas Program Patent Rights in any or all countries in the Territory in which Arvinas has elected not to pursue such actions in Arvinas’ name and at Bayer’s expense, subject to Section 7.2.4(c).  

(b)

Joint Collaboration IP.  With respect to Joint Collaboration IP, Bayer shall have the first right to Prosecute and Maintain patent applications within the Joint Patent Rights in the joint names of the Parties, at its own expense. Bayer may elect not to Prosecute or Maintain any such patent applications in any country in the Territory and if so, Bayer shall notify Arvinas and Arvinas shall have the right to Prosecute and Maintain such patent applications in the joint names of the Parties, at Arvinas’ own expense, in any or all countries in the Territory in which Bayer has elected not to Prosecute or Maintain such patent applications, subject to Section 7.2.4(c). Notwithstanding the foregoing, Patent Rights shall only be filed on Joint Collaboration IP as mutually agreed by the Parties in writing, which agreement shall address and govern rights to use, practice and license such Joint Patent Rights, such agreement to not be unreasonably withheld or delayed.

(c)

Consultation.  In each case with respect to Arvinas Program Patent Rights and Joint Patent Rights, the Prosecuting Party, as relevant (“Filing Party”) shall give the other Party an opportunity to review the text of any application before filing, shall consult with the non-Filing Party with respect thereto, and shall supply the non-Filing Party with a copy of the application as filed, together with notice of its filing date and serial number.  The Filing Party shall keep the non-Filing Party advised of the status of the actual and prospective patent filings and, upon the non-Filing Party’s request, shall provide advance copies of any papers related to the Prosecution or Maintenance of such patent filings.  The Filing Party shall regularly provide the other Party with copies of all material submissions and correspondence with the patent offices, in sufficient time to allow for review and comment by the non-Filing Party.  The Filing Party shall provide the non-Filing Party and its patent counsel with an opportunity to consult with the Filing Party and its patent counsel

regarding the filing and contents of patent applications, amendments, submissions or responses, and the advice and suggestions of the non-Filing Party and its patent counsel shall be taken into consideration in good faith by the Filing Party and its patent counsel.  Each Filing Party shall pursue in good faith all reasonable claims and arguments requested by the non-Filing Party in the Prosecution of any Arvinas Program Patent Rights or Joint Patent Rights. Each Party agrees to execute and deliver, at the reasonable request and sole expense of the Filing Party all papers, instruments and assignments, and to perform any other reasonable acts as the Filing Party may require, in order for such Party to pursue relevant patent applications in accordance with this Section 7.2.4.  Each Party shall promptly give notice to the other Party of the grant, lapse, revocation, surrender, invalidation or abandonment of any Patent Rights for which such Party is responsible under this Section 7.2.4 for Prosecution and Maintenance.  With respect to all filings hereunder, the Filing Party (as of the relevant time such cost or expense is incurred) shall be responsible for payment of all costs and expenses related to such filings.  

7.2.5

Procedures.  Notwithstanding any other provision hereof, each Party shall use all reasonable efforts to, in activities conducted in accordance with this Section 7.2, file Patent Rights claiming inventions in such a manner as to ensure that Collaboration Compounds and uses of Collaboration Compounds are not claimed in the same patent applications as those claiming either inventions within PROTAC Improvement IP or inventions that are applicable to PROTACs in general.  In the event that either Party reasonably believes that it cannot file such claims in separate filings, such Party shall consult with the other Party regarding such matter and cooperate in good faith with such other Party to effect a solution regarding ownership of and rights to any relevant Patent Rights claiming such mixed inventions consistent with the intent of the other relevant provisions of this Agreement.  In situations where, subject to compliance with the foregoing requirements, a patent application of mixed inventions claims PROTAC Improvement IP and Collaboration Compound IP (a “Mixed Application”), Bayer shall own any such Mixed Application. Bayer hereby grants to Arvinas an exclusive (even as to Bayer but subject to any relevant rights expressly granted to Bayer in Section 3.1), worldwide, perpetual, fully-paid license, with the right to sublicense, under such Mixed Applications to practice any PROTAC Improvement IP or Arvinas Collaboration IP specifically or generically claimed therein for Arvinas’ internal programs or in connection with programs conducted by or on behalf of Third Parties who license Arvinas’ protein degradation technology, but in all cases not with respect to any Collaboration Target that is included under a License granted under this Agreement at the relevant time.  For clarity, such license to Arvinas is exclusive only with respect to PROTAC Improvement IP and Arvinas Collaboration IP.  Prosecution, and Maintenance and enforcement of any such Mixed Applications shall be performed in accordance with Sections 7.2.4(b) and 7.5 as for Joint Collaboration IP and Joint Patent Rights.  

7.3

Bayer Patent Rights. Bayer shall have the exclusive right, at its sole expense, to file, prosecute and maintain any and all Bayer Patent Rights.  Bayer shall also have the sole and exclusive right to enforce and defend the Bayer Patent Rights, including without limitation any interference, opposition, reissue or reexamination proceeding relating to Bayer Patent Rights and any infringement of Bayer Patent Rights.

7.4

Interference, Opposition, Reexamination and Reissue.

7.4.1

Arvinas shall, within [**] of any of its executive officers learning of such event, inform Bayer of any request for, or filing or declaration of, any interference, opposition, reissue or reexamination relating to Arvinas Patent Rights which Cover the Development or Commercialization of any Collaboration Compound or Product exclusively licensed by Bayer hereunder, to Collaboration Compound Patent Rights or to Joint Patent Rights.  Bayer shall, within [**] of any of its executive officers learning of such event, inform Arvinas of any request for, or filing or declaration of, any interference, opposition, reissue or reexamination relating to Arvinas Patent Rights which Cover the Development or Commercialization of any Collaboration Compound or Product exclusively licensed by Bayer hereunder, to Collaboration Compound Patent Rights or to Joint Patent Rights. Bayer and Arvinas shall thereafter consult and cooperate fully to determine a course of action with respect to any such proceeding.  Bayer shall have the right to review and approve any submission to be made in connection with such proceeding.

7.4.2

Notwithstanding Section 7.2, Arvinas shall not initiate any reexamination, interference or reissue proceeding relating to Arvinas Patent Rights Covering the Development or Commercialization of any Collaboration Compound or Product exclusively licensed by Bayer hereunder or to Joint Patent Rights without the prior written consent of Bayer, which consent shall not be unreasonably withheld or delayed, and Bayer shall not initiate any reexamination, interference or reissue proceeding relating to Arvinas Patent Rights Covering the Development or Commercialization of any Collaboration Compound or Product exclusively licensed by Bayer hereunder, to Collaboration Compound Patent Rights having Arvinas representatives as inventors or to Joint Patent Rights without the prior written consent of Arvinas, which consent shall not be unreasonably withheld or delayed.

7.4.3

In connection with any interference, opposition, reissue, or reexamination proceeding relating to Arvinas Patent Rights, Collaboration Compound Patent Rights or Joint Patent Rights, Bayer and Arvinas shall cooperate fully and shall provide each other with any information or assistance that either may reasonably request. For Arvinas Patent Rights Covering the Development or Commercialization of any Collaboration Compound or Product exclusively licensed by Bayer hereunder, Collaboration Compound Patent Rights having Arvinas representatives as inventors or Joint Patent Rights, the responsible Party shall keep the other Party informed of developments in any such action or proceeding, including, to the extent permissible by applicable Laws, consultation and approval of any settlement, the status of any settlement negotiations and the terms of any offer related thereto.

7.4.4

Arvinas shall bear the expense of any interference, opposition, reexamination, or reissue proceeding that Arvinas elects to Prosecute and Maintain as provided herein.  Bayer shall control and bear the expense of any interference, opposition, reexamination, or reissue proceeding that Bayer elects to Prosecute and Maintain as provided herein.

7.4.5

Regardless of which Party has the right to initiate and prosecute such action, both Parties shall, as soon as practicable after receiving notice of such action, convene and consult with each other regarding the appropriate course of conduct for such action.  The non-initiating Party shall have the right to be kept fully informed and participate in decisions regarding the appropriate course of conduct for such action, and the right to join and participate in such action.

7.5

Enforcement and Defense.

7.5.1

Each Party shall give the other Party notice of either (i) any infringement of Arvinas Patent Rights, Collaboration Compound Patent Rights or Joint Patent Rights, or (ii) any misappropriation or misuse of Licensed IP, in each case that is reasonably relevant to the Development or Commercialization of any Collaboration Compound or Product exclusively licensed by Bayer hereunder and that comes to such Party’s attention.  Bayer and Arvinas shall thereafter consult and cooperate fully to determine a course of action, including the commencement of legal action by either or both Bayer and Arvinas, to terminate any such infringement of Arvinas Patent Rights, Collaboration Compound Patent Rights, or Joint Patent Rights, or any such misappropriation or misuse of Licensed IP, subject to the provisions set forth below.  

7.5.2

Except as provided under Section 7.6, Arvinas, upon notice to Bayer, shall have the first right to initiate and prosecute any such legal action at its own expense, or to control the defense of any declaratory judgment action, relating to Arvinas Patent Rights or other Licensed IP. Bayer shall have the right to join any such action initiated by Arvinas to the extent permissible by law.  With respect to any such legal action regarding an infringement of any Arvinas Patent Right that directly impacts any exclusive rights of Bayer hereunder regarding any Collaboration Compound or Product, if Arvinas does not initiate any such legal action, at least [**] prior to the deadline for bringing an action without resulting loss of rights, upon any written request by Bayer for Arvinas to do so following consultation in accordance with Section 7.5.1, Bayer shall have the right, but shall not be obligated, to bring an infringement action with respect to such infringement solely to the extent directly related to Bayer’s exclusive rights hereunder (i.e., not related to any PROTACs directed to any target other than a Collaboration Target) at its own expense, and under its own direction and control, or settle any such action, proceeding or dispute by license, subject to the following.  Arvinas shall have the right to participate and be represented in any such suit by its own counsel at its own expense, provided that Bayer shall retain overall responsibility for the prosecution of such suit or proceedings in such event.  No settlement of any such action or proceeding which restricts the scope, or adversely affects the enforceability, of an Arvinas Patent Right, or which could be reasonably expected to have a material adverse financial impact on Arvinas, may be entered into by Bayer without the prior written consent of Arvinas, which consent shall not be unreasonably withheld, delayed or conditioned.

7.5.3

Bayer, upon notice to Arvinas, shall have the right to initiate and prosecute any legal action at its own expense and in the name of Arvinas and Bayer, as applicable, or to control the defense of any declaratory judgment action, relating to Collaboration Compound Patent Rights or Joint Patent Rights.  Bayer shall promptly inform Arvinas if it elects not to exercise such right with respect to any Joint Patent Right and Arvinas shall thereafter, unless otherwise agreed by the Parties in writing, have the right to either initiate and prosecute such action or to control the defense of such declaratory judgment action with respect to such Joint Patent Right.  Each Party shall have the right to be represented by counsel of its own choice.  No settlement of any such action or proceeding which restricts the scope, or adversely affects the enforceability, of any Collaboration Compound Patent Right or Joint Patent Right, or which could reasonably be expected to have a material adverse financial impact on the other Party, may be entered into by either Party without the prior written consent of the other Party, which consent shall not be unreasonably withheld, delayed or conditioned.

7.5.4

For any action to terminate any infringement of Arvinas Patent Rights, Collaboration Compound Patent Rights or Joint Patent Rights, or any misappropriation or misuse of Licensed IP, in the event that a Party is unable to initiate or prosecute any such action permitted hereunder solely in its own name, the other Party shall join such action voluntarily and shall execute and cause its Affiliates to execute all documents necessary for such Party to initiate litigation to prosecute and maintain such action.  If Yale University is required to join as a party in such action, Arvinas shall use all reasonable efforts to cause Yale University to join and provide reasonable assistance. In connection with any action brought hereunder, Bayer and Arvinas shall cooperate fully and shall provide each other with any information or assistance that either may reasonably request.  The requesting Party shall reimburse the other Party for the documented external costs the other Party reasonably incurs in providing any such assistance as specifically requested in writing.  Each Party shall keep the other informed of developments in any action or proceeding, hereunder including, to the extent permissible by applicable Laws, consultation on and approval of any settlement, the status of any settlement negotiations and the terms of any offer related thereto.

7.5.5

If either Party brings an action or proceeding under this Section 7.5 and subsequently ceases to pursue or withdraws from such action or proceeding, it shall promptly notify the other Party and the other Party may substitute itself for the withdrawing Party under the terms of this Section 7.5.

7.5.6

In the event that either Party exercises the rights conferred in this Section 7.5 and recovers any damages or other sums in such action, suit or proceeding or in settlement thereof, such damages or other sums recovered shall first be applied to all out-of-pocket costs and expenses incurred by the Parties in connection therewith, including attorneys’ fees.  Except as otherwise provided in this Section 7.5, each Party shall bear its own expenses with respect to any suit or other proceeding against an infringer.  If such recovery is insufficient to cover all out-of-pocket costs and expenses of both Parties, it shall be shared in proportion to the total of such costs and expenses incurred by each Party.  If after such reimbursement any funds shall remain from such damages or other sums recovered, such funds shall be divided as follows: (i) as to ordinary damages based on lost sales or profit, a) if Bayer is the Party bringing suit or bears [**]% of the out-of-pocket costs and expenses of Arvinas in such action, or if Arvinas is the Party bringing suit but Bayer has agreed as of the initiation of such action to bear [**] percent ([**]%) of the out-of-pocket costs and expenses incurred by Arvinas in connection therewith, Bayer shall retain such funds and Arvinas shall receive payment equivalent to royalty payments that would have been due to Arvinas under this Agreement had the infringing sales that Bayer lost to the infringer been made by Bayer in the Calendar Year in which the payment for damages or other settlement is received, c) and if Arvinas is the Party bringing suit and Bayer has not agreed as of the initiation of such action to bear [**] percent ([**]%) of the out‑of-pocket costs and expenses incurred by Arvinas in connection therewith, Arvinas shall retain [**] percent ([**]%) of such funds and provide [**] percent ([**]%) thereof to Bayer, and (ii) as to special or punitive damages, the Parties shall collect in proportion to the ordinary damages received, provided that Arvinas shall in any event receive at least [**] percent ([**]%) thereof.  

7.5.7

Bayer acknowledges that, except for the obligation to provide reasonable assistance, at the request and expense of the relevant Party bringing suit, with respect to any actions relating to the Yale Licensed Patents, Yale University shall have no obligation to participate in any of the legal actions described in this Section 7.5 unless required to do so by applicable Laws.  If, in the reasonable opinion of both Bayer’s and Yale University’s respective counsel, Yale University is required to be a named party to any such suit for standing purposes, Bayer may join Yale University as a party; provided, however, that (i) Yale University shall not be the first named party in any such action, (ii) the pleadings and any public statements about the action shall state that the action is being pursued by Bayer and that Bayer has joined Yale University as a party; and (iii) Bayer shall keep Yale University reasonably apprised of all developments in any such action. However and in addition, Yale University shall have the right to participate in any such action through its own counsel and at its own expense.

7.5.8

Notwithstanding the foregoing, neither Bayer nor Arvinas shall have any right to take any action to enforce the Yale Licensed Patents in any of the low income countries listed on Schedule 7.5.8 where such action is intended to prevent the sale of products Covered by such Yale Licensed Patents in any such countries.  However, Bayer or Arvinas may take such action in any such country, provided that such action is intended to prevent the manufacturing, processing, packaging or holding (including storage) of products Covered by such Yale Licensed Patents for export to countries that are not countries listed on Schedule 7.5.8.

7.6

Patent Certification and Enforcement and Defense against Generic Applicant.  Arvinas shall inform Bayer of any certification reasonably relevant to the Development or Commercialization of any Collaboration Compound or Product exclusively licensed by Bayer hereunder regarding any Arvinas Patent Rights, Collaboration Compound Patent Right or Joint Patent Rights that it has received pursuant to either 21 U.S.C. §§355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or its successor provisions or any similar provisions in a country in the Territory other than the United States, and shall provide Bayer with a copy of such certification within [**] of receipt. Bayer shall inform Arvinas of any certification reasonably relevant to the Development or Commercialization of any Collaboration Compound or Product exclusively licensed by Bayer hereunder regarding any Arvinas Patent Rights or Joint Patent Rights that it has received pursuant to either 21 U.S.C. §§355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or its successor provisions or any similar provisions in a country in the Territory other than the United States, and shall provide Arvinas with a copy of such certification within [**] of receipt.  For countries in which there is no patent certification procedure or similar provision, each Party shall promptly give the other party notice of any Generic registration, marketing approval or launch activity relating to any Product exclusively licensed by Bayer hereunder regarding any Arvinas Patent Rights or Joint Patent Rights.   Arvinas’ and Bayer’s rights with respect to the initiation and prosecution of any legal action as a result of such certification or activity or any recovery obtained as a result of such legal action shall be as defined in Section 7.5; provided, however, that with respect to Arvinas Patent Rights, Bayer shall have the first right to initiate and prosecute any such action, at its own expense, and shall inform Arvinas of such decision within [**] of the notification or Bayer’s receipt of the certification, after which time Arvinas shall have the right to initiate and prosecute such action, at its own expense.  Regardless of which Party has the right to initiate and prosecute such action, both Parties shall, as soon as practicable after receiving notice of such certification or activity, convene and consult with each other regarding the appropriate course of conduct for such action.  The non-initiating Party shall have the right to be kept fully informed and participate in decisions regarding the appropriate course of conduct for such action, and the right to join and participate in such action.

7.7

Patent Term Restoration and Extension.  The Parties agree to cooperate and to take reasonable actions to maximize the protections available under the provisions of 35 U.S.C. 102(c) under the ▇▇▇▇▇-▇▇▇▇▇ America Invents Act for US patents and patent applications, as well as any and all patent extension provisions outside of the USA.  The Parties shall cooperate with each other, including by providing necessary information and assistance as the other Party may reasonably request, in obtaining patent term extensions or supplemental protection certificates or their equivalents in any country in the Territory where applicable to Arvinas Patent Rights, Collaboration Compound Patent Rights or Joint Patent Rights and reasonably relevant to the Development or Commercialization of any Collaboration Compound or Product exclusively licensed by Bayer hereunder.  In the event that elections with respect to obtaining such patent term extensions are to be made with respect to any Patent Right claiming an Invention that specifically claims Collaboration Compounds or Products subject to an exclusive license granted to Bayer hereunder, Bayer shall have the right to make the election and Arvinas agrees to abide by such election.

7.8

Infringement Claims. Each of Arvinas and Bayer shall promptly inform the other in writing of any written notice to it of alleged infringement or misappropriation, based on the making, using, keeping, importing, exporting or selling of a Product, of a Third Party’s intellectual property rights of which it shall become aware.  Neither Party shall acknowledge to a Third Party the validity of any such allegation or admit liability without the prior written consent of the other Party, such consent to not be unreasonably withheld or delayed.  Bayer and Arvinas shall each keep the other advised of all material developments in the conduct of any proceedings in defending any claim of such alleged infringement or misappropriation and shall cooperate with the other in the conduct of such defense.  In no event may either Party settle any such infringement or misappropriation claim in a manner that would limit the rights of the other Party or impose any obligation on the other Party, without such other Party’s prior written consent, such consent not to be unreasonably withheld or delayed.

7.9

Patent Marking.  Solely with respect to Yale Licensed Patents, to the extent commercially feasible and consistent with Bayer business practices, Bayer shall use commercially reasonable efforts to ▇▇▇▇, and shall cause its Related Parties to use commercially reasonable efforts to ▇▇▇▇, all Products that are manufactured or sold under this Agreement with the number of each issued Yale Licensed Patent Controlled by Arvinas that applies to such Products.

Licensed Patent Challenges (Yale Agreement). The Parties acknowledge and agree that, pursuant to the Yale Agreement, Arvinas has certain obligations and may incur penalties based on (i) any challenge or opposition to the validity, patentability, enforceability or non-infringement of any of the Yale Licensed Patents (as defined herein and under the Yale Agreement), or any actions otherwise opposing any of such Yale Licensed Patents, if brought by a sublicensee of Arvinas (e.g., Bayer or its Sublicensees under this Agreement) anywhere in the world, or (ii) any assistance with respect to any of the foregoing actions which Bayer or any of its Sublicensees provides to a Third Party anywhere in the world (except as required under a court order or subpoena) (any such action or assistance under (i) or (ii), a “Licensed Patent Challenge”). Accordingly, Bayer hereby agrees to indemnify and hold Arvinas harmless with respect to any damages incurred by Arvinas under Section 6.3 of the Yale Agreement as a result of any Licensed Patent Challenge by Bayer or its Sublicensees.  For avoidance of doubt, Bayer does not agree to indemnify Arvinas for any Licensed Patent Challenge brought by Arvinas, its Affiliates or any of its other sublicensees with respect to the Yale Agreement.   In addition, Bayer hereby agrees that neither Bayer nor any of its Sublicensees shall bring a Licensed Patent Challenge without first providing Arvinas and Yale University with at least [**] prior written notice setting forth (a) those claims and patents that will be challenged or claimed not to be infringed, (b) a  statement of the factual and legal basis for the challenge, and (c) an identification of  prior art and other matters believed to invalidate any claim of a Yale Licensed Patent or which supports the claim that a Yale Licensed Patent is not infringed.

8.1

Term and Expiration.  This Agreement shall be effective as of the Effective Date and unless terminated earlier pursuant to Sections 8.2 or 8.3, this Agreement shall continue in full force and effect until one or more Products has received Marketing Authorization and, thereafter, until expiration of all payment obligations pursuant to Sections 5.3 and 5.4.  

8.2

Termination by Bayer.   Notwithstanding anything contained herein to the contrary, Bayer shall have the right to terminate this Agreement, either in its entirety or in relation to any Collaboration Target and relevant Collaboration Compounds and Products under this Agreement, at any time for any or no reason in its sole discretion by giving sixty (60) days’ advance written notice to Arvinas.

8.3

(b)

by either Party upon the filing or institution of bankruptcy, reorganization, liquidation or receivership proceedings, or upon an assignment of a substantial portion of the assets for the benefit of creditors by the other Party; provided, however, that in the case of any involuntary bankruptcy proceeding such right to terminate shall only become effective if the Party consents to the involuntary bankruptcy or such proceeding is not dismissed within [**] after the filing thereof.

(c)

Notwithstanding the foregoing, any termination of this Agreement by Bayer pursuant to Section 8.3.1(a) shall apply to this Agreement in its entirety, or be limited in force and effect to the Collaboration Target to which such material breach relates, as Bayer may elect in its sole discretion in writing at the time of termination, and any termination of this Agreement by Arvinas pursuant to Section 8.3.1(a) for breach shall be limited in force and effect to the Collaboration Target(s) (and related Collaboration Compounds and Products) to which such material breach relates.

All licenses and rights to licenses granted under or pursuant to this Agreement by Arvinas to Bayer are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code (i.e., Title 11 of the U.S. Code) (the “Code”), licenses of rights to “intellectual property” as defined under Section 101(35A) of the Code.  If (a) a case under the Code is commenced by or against Arvinas, (b) this Agreement is rejected as provided in the Code and (c) Bayer elects to retain its rights hereunder as provided in Section 365(n) of the Code, then Arvinas (in any capacity, including debtor-in-possession) and its successors and assigns (including any trustee) shall provide to Bayer all intellectual property licensed by Bayer hereunder, and agrees to grant and hereby grants to Bayer and its Affiliates a right to access and to obtain possession of and to benefit from and, in the case of any chemical or biological material or other tangible item of which there is a fixed or limited quantity, to obtain a pro rata portion of, all “embodiments” of intellectual property licensed hereunder pursuant to Section 365(n) of the Bankruptcy Code, and all other embodiments of such intellectual property in the possession and

control of any Third Party but which Arvinas has the right to access or benefit from and to make available to Bayer. Arvinas shall not interfere with the exercise by Bayer or its Affiliates of rights and licenses to intellectual property licensed hereunder and embodiments thereof in accordance with this Agreement. The foregoing provisions of this Section 8.4.3 (d) are without prejudice to any rights Bayer may have arising under the Code or other applicable Laws.

8.4.4

Additional Effects of Expiration or Termination; Survival.  Notwithstanding any other provision of this Article 8, (a) expiration or termination of this Agreement shall not relieve the Parties of any obligation (including any payment obligation) accruing prior to such expiration or termination, (b) any expiration or termination of this Agreement shall be without prejudice to the rights of either Party against the other accrued or accruing under this Agreement prior to expiration or termination, including the obligation to pay royalties for Product or Collaboration Compound sold prior to such expiration or termination, and (c) the provisions of Article 1, Article 4, Article 6, Article 7, Article 8, Article 9 and Article 10, and Sections 2.6.1, 2.6.2, 2.7, 2.9, 2.10, 2.11, 3.1.4, 3.3, 5.5, 5.6, 5.7, 5.8, 5.9, 5.10, 5.11, 5.12 and 5.13, shall survive any expiration or termination of this Agreement.

9.1

Bayer Indemnity Obligations.  Bayer agrees to defend Arvinas, its Affiliates and their respective directors, officers, employees and agents (collectively, the “Arvinas Indemnitees”), and shall indemnify and hold harmless the Arvinas Indemnitees, from and against any liabilities, losses, costs, damages, fees or expenses payable to a Third Party, and reasonable attorney’s fees and other legal expenses with respect thereto, arising out of any claim, action, lawsuit, or other proceeding (collectively, “Losses and Claims”) brought against any Arvinas Indemnitee by a Third Party to the extent resulting from or relating to: (a) the manufacture, use, handling, storage, sale or other disposition of any Collaboration Compound or Product in the Territory by Bayer or its Related Parties, including product liability claims, (b) any breach by Bayer of any of its representations, warranties or obligations pursuant to this Agreement, or (c) the gross negligence or willful misconduct of Bayer or any Related Party; except in any such case to the extent such Losses and Claims result from: (i) the gross negligence or willful misconduct of any Arvinas Indemnitee, or (ii) any breach by Arvinas of any of its representations, warranties or obligations pursuant to this Agreement.

9.2

Arvinas Indemnity Obligations.  Arvinas agrees to defend Bayer, its relevant Related Parties and their respective directors, officers, employees and agents (collectively, the “Bayer Indemnitees”), and shall indemnify and hold harmless the Bayer Indemnitees, from and against any Losses and Claims brought against any Bayer Indemnitee by a Third Party to the extent resulting from or relating to: (a) any personal injury claims arising in the course of the performance by Arvinas, its Affiliates or its subcontractors of its activities under the Research Program, (b) any breach by Arvinas of any of its representations, warranties or obligations pursuant to this Agreement, or (c) the gross negligence or willful misconduct of any Arvinas Indemnitee.

9.3

Procedure.  If any Arvinas Indemnitee or Bayer Indemnitee (each, an “Indemnitee”) intends to claim indemnification under this Article 9, the Indemnitee shall promptly notify the other Party (the “Indemnitor”) of any Losses and Claims for which the Indemnitee intends to claim such indemnification, and the Indemnitor shall assume the defense thereof with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee, provided, however, that an Indemnitee

shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee (and, for clarity, not to be included in Losses and Claims), if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other Party represented by such counsel in such proceedings.  The Indemnitor shall have the right to settle or compromise any claims for which it is providing indemnification under this Article 9, provided that the consent of the Indemnitee (which shall not be unreasonably withheld or delayed) shall be required in the event any such settlement or compromise would adversely affect the interests of the Indemnitee.  The indemnity agreement in this Article 9 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Indemnitor.  The failure to deliver notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to the Indemnitor’s ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 9, but the omission so to deliver notice to the Indemnitor shall not relieve it of any liability that it may have to any Indemnitee otherwise than under this Article 9.  The Indemnitee under this Article 9, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action, claim or liability covered by this indemnification.

9.4

Limitation of Liability.  Neither Party hereto shall be liable for indirect, incidental, consequential, special, exemplary, punitive or multiple damages arising in connection with this Agreement or the exercise of its rights hereunder, or for lost profits arising from or relating to any breach of this Agreement, regardless of any notice of such damages, provided, however, that this Section 9.4 shall not limit or restrict (i) damages available for breaches of confidentiality obligations Article 4 or (ii) the indemnification obligations of either Party pursuant to this Article 9.

9.5

Insurance.  Each Party warrants that it maintains a policy or program of insurance or self-insurance at levels sufficient to support the indemnification obligations assumed herein.  Upon request, a Party shall provide evidence of such insurance.

10.1

Force Majeure. Neither Party shall be held liable to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in performing any obligation under this Agreement to the extent such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party, potentially including embargoes, war, acts of war (whether war be declared or not), acts of terrorism, insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, or other acts of God, or acts, omissions or delays in acting by any governmental authority or the other Party.  The affected Party shall notify the other Party of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake all reasonable efforts necessary to cure such force majeure circumstances.

10.2

Assignment.   

10.2.1

Except as provided in this Section 10.2, this Agreement may not be assigned or otherwise transferred, nor may any right or obligation hereunder be assigned or transferred, by either Party without the consent of the other Party. Any attempted assignment not in accordance with this Section 10.2 shall be void.  Any permitted assignee shall assume all assigned obligations of its assignor under this Agreement.

10.2.2

Bayer may, without consent of Arvinas, assign this Agreement and its rights and obligations hereunder in whole or in part to an Affiliate of Bayer or to the successor party in connection with a Change of Control.  Arvinas may, without consent of Bayer, assign this Agreement in its entirety to the successor party in connection with a Change of Control. Each Party agrees that, notwithstanding any provisions of this Agreement to the contrary, in the event that this Agreement is assigned by a Party in connection with a Change of Control, such assignment shall not provide the non-assigning Party with rights or access to independently owned or acquired intellectual property or technology of the acquirer of the assigning Party.

10.3

Use of Affiliates.  Bayer shall have the right to exercise its rights and perform its obligations under this Agreement either itself or through any of its Affiliates, provided that Bayer shall at all times remain liable for the actions or inactions of any such Affiliate.

10.4

Severability.  If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties.  The Parties shall in such an instance use reasonable efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.

10.5

Notices.  All notices which are required or permitted hereunder shall be in writing and sufficient if delivered personally, sent by nationally-recognized overnight courier providing evidence of receipt, or sent by registered or certified mail, postage prepaid, return receipt requested, addressed as follows:

A Party may submit such dispute to arbitration by notifying the other Party, in writing, of such dispute. Within [**] after receipt of such notice, each Party shall designate in writing one arbitrator and the two Party-selected arbitrators shall select a third arbitrator with relevant industry experience to constitute a panel of three arbitrators to conduct the arbitration in accordance with the ICC Rules.

10.7.4

The determination of the arbitrators as to the resolution of any dispute shall be binding and conclusive upon all Parties. All rulings of the arbitrators shall be in writing and shall be delivered to the Parties except to the extent that the ICC Rules provide otherwise.

10.7.5

The (i) attorneys’ fees of the Parties in any arbitration, (ii) fees of the arbitrator and (iii) costs and expenses of the arbitration shall be borne by the Parties in a proportion determined by the arbitrators.

The Parties agree that any payments that are made by one Party to the other Party pursuant to this Agreement pending resolution of any dispute shall be promptly refunded if the arbitrators or a court determine(s) pursuant to this Section 10.7 that such payments are to be refunded by one Party to the other Party.

10.11

Waiver.  The waiver by either Party hereto of any right hereunder, or of any failure of the other Party to perform, or of any breach by the other Party, shall not be deemed a waiver of any other right hereunder or of any other breach by or failure of such other Party whether of a similar nature or otherwise.

appear, (c) words using the singular shall include the plural, and vice versa, (d) the words “include”, “includes” and “including” shall be deemed to be followed by the phrase “without limitation”, (e) the word “will” shall be construed to have the same meaning and effect as the word “shall”, and (f) the word “any” shall mean “any and all” unless otherwise clearly indicated by context, (h) the word “notice” means notice in writing (whether or not specifically stated) and shall include notices, consents, approvals and other written communications contemplated under this Agreement, (i) provisions that require that a Party, the Parties or any committee hereunder “agree,” “consent” or “approve” or the like shall require that such agreement, consent or approval be specific and in writing, whether by written agreement, letter, approved minutes or otherwise (but excluding e-mail and instant messaging), (j) references to any specific law, rule or regulation, or article, section or other division thereof, shall be deemed to include the then-current amendments thereto or any replacement or successor law, rule or regulation thereof, and (k) the term “or” shall be interpreted in the inclusive sense commonly associated with the term “and/or.”
