Upon the written request and for the benefit of Licensee, TESARO shall (a) exercise its right under Section 3.2(a) of the ▇▇▇▇▇▇▇ Agreement to request that ▇▇▇▇▇▇▇ ▇▇▇▇▇ to TESARO a non-exclusive, royalty-bearing, non-transferable license, with the right to grant sublicenses, under the Company Technology to Exploit Products in Japan on commercially reasonable terms, and (b) use reasonable efforts to, in consultation with and subject to the approval by Licensee of the final terms of such license, negotiate and agree on the terms of such license with ▇▇▇▇▇▇▇ and, if applicable, participate in the dispute resolution process set forth in Section 3.2(a) of the ▇▇▇▇▇▇▇ Agreement if TESARO and ▇▇▇▇▇▇▇ are unable to reach agreement on the terms of such license; provided, that [***] any royalties, consideration or other amounts payable to ▇▇▇▇▇▇▇ in connection with any such license.

Section 2.6

Limited Exploitation Rights. Without limiting the provisions of Section 2.5, Licensee agrees (on behalf of itself and its Affiliates), and shall cause each of its Sublicensees to agree, not to use any Licensed Know-How or Licensed Patents for any products other than the Product, in any field other than the Licensed Field or outside the Licensed Territory.

Section 2.7

2.7.1 Exclusivity. As partial consideration for TESARO granting to Licensee the license set forth in Section 2.1, during the Term, Licensee shall not, and shall cause its Affiliates to not, itself or in cooperation with or through others, in the Licensed Territory, discover, research, develop, manufacture or commercialize any PARP Inhibitor other than the Licensed Compound and Product hereunder. In the event Licensee wishes to obtain the right (by licensing, merger or acquisition or otherwise) to discover, research, develop, manufacture or commercialize any PARP Inhibitor other than the Licensed Compound and Product in the Licensed Territory, Licensee shall notify TESARO in writing, and TESARO may determine, [***]. Without limitation of the foregoing, Licensee shall not use, or provide to others,

2.7.2 Permitted Distribution Activities. Notwithstanding the first sentence of Section 2.7.1, Licensee shall have the right to distribute any pharmaceutical products containing a PARP Inhibitor other than the Licensed Compound and Product in the Licensed Territory if and only if Licensee is obligated to distribute such pharmaceutical products through its wholesaler channels under any agreement that has been executed prior to the Effective Date (the “Pre-Effective Date Wholesaler Agreements”) (such activities, the “Permitted Distribution Activities”). For clarity, the Permitted Distribution Activities shall be limited to the distribution of the products described in the foregoing sentence and shall not include the right to promote, market or otherwise engage in any other activities to commercialize such products. [***].

2.7.3 Licensee Covenants. Licensee shall notify TESARO in writing within thirty (30) days if (a) Licensee or any of its Affiliates acquires rights to any PARP Inhibitor outside the Licensed Territory, (b) Licensee, by itself, through an Affiliate or in cooperation with or through others, commences the research, development, manufacture or commercialization of any PARP Inhibitor other than the Licensed Compound and Product outside the Licensed Territory, or (c) Licensee or any of its Affiliates becomes obligated to conduct Permitted Distribution Activities under a Pre-Effective Date Wholesaler Agreement.

Section 3.1

Upfront Payment. Within [***] of the Effective Date, Licensee shall pay to TESARO a one-time, non-refundable, non-creditable upfront payment of One Hundred Million Dollars (US$100,000,000). Notwithstanding the immediately above, if TESARO breaches its representation and warranty set forth in Section 6.2(k) below and such representation and warranty is not true and correct within thirty (30) days of the Effective Date, then upon written request of Licensee, TESARO shall refund to Licensee Thirty Million Dollars (US$30,000,000) within ten (10) days of such request, as the sole and exclusive remedy of Licensee for a breach of such representation and warranty, and thereafter the Licensed Territory shall only include Japan.

Notwithstanding the foregoing, if Licensee’s Development activities cause TESARO to owe Merck a milestone payment under the “Development Milestone” section of Section 7.02 of the Merck Agreement but no corresponding Milestone Payment is payable by Licensee to TESARO under this Section 3.2, then Licensee shall pay to TESARO for payment to Merck, in accordance with the terms of this Agreement, or Licensee and TESARO shall coordinate to enable Licensee to pay directly to Merck, the amount of the milestone payment owed by TESARO to Merck.

Section 3.3

Royalties.

3.3.1 Royalty Rate. Subject to the remainder of this Section 3.3, Licensee shall pay to TESARO on a Product-by-Product basis a running royalty on Net Sales of each Product sold by Licensee, its Affiliates and Sublicensees in the Licensed Field in the Licensed Territory at the rates forth in Section 2 of Exhibit C for the duration of the Royalty Term (collectively, “Royalties”).

3.3.2 Royalty Reductions.

(a)

If a Product is generating Net Sales in a country in the Licensed Territory during the Royalty Term at a time when there is no Licensed Patent in such country that contains a Valid Claim Covering the composition of matter or use of the Licensed Compound included in such Product, then the Royalty rate applicable to the Net Sales in such country for such Product shall be reduced by [***].

(b)

In the event that Licensee is required to obtain a license under any Patent Rights from any Third Party(ies) in order to make, have made, use, offer to sell, sell or import the Licensed Compounds, (i) [***] of the royalties actually paid under such Third Party Patent Right licenses by Licensee in connection with the Manufacture, use, sale or import, as applicable, of the Licensed Compound in a country for a Calendar Quarter shall be creditable against the Royalty payments due TESARO by Licensee with respect to the sale of such Licensed Compound in such country; provided, however, that in no event shall the Royalties owed by Licensee to TESARO for such Calendar Quarter in such country be reduced by more than [***] pursuant to this Section 3.3.2(b); or (ii) if no royalty is paid, or in addition to a royalty, a lump sum payment is made for such Third Party Patent Right licenses, then [***] of the lump sum payment actually paid shall be creditable against the next Milestone Payment then due TESARO under Section 3.2; provided, however, that in no event shall the aggregate payments to be creditable against Milestone Payments due TESARO exceed [***].

(c)

If at any time Generic Competition exists in a given country with respect to a Product, then Licensee’s obligation to pay Royalties with respect to such Product in such country shall be reduced by [***] effective as of the first date when Generic Competition exists with respect to such Product in such country.

3.3.3 Minimum Royalties. Notwithstanding the foregoing, the Royalties due from Licensee to TESARO under this Agreement with respect to the Net Sales of the Product in the Licensed Territory in a particular Calendar Quarter shall be no less than the royalties owed by TESARO to Upstream Licensors under the Upstream Agreements with respect to such Net Sales plus [***] of such Net Sales. Licensee shall make to TESARO any payments necessary to give effect to this Section 3.3.3 with thirty (30) days after TESARO provides written notice thereof.

3.3.4 Upstream Royalties. TESARO shall be solely responsible for the payment of royalties and other payments owed by TESARO to Upstream Licensors on account of the Development, Manufacture and Commercialization of the Product by Licensee in the Licensed Territory.

Section 3.4

Manner of Payment. All payments to be made by Licensee hereunder shall be made in U.S. Dollars by wire transfer of immediately available funds to such bank account as shall be designated by TESARO. Except as otherwise provided in this Agreement, all payments to be made by Licensee under this Agreement shall be due within [***] of the date of invoice. Late payments shall bear interest at the rate provided in Section 3.8.

Section 3.5

Sales Reports and Royalty Payments. Any Royalty payments due under this Agreement will be calculated and reported for each Calendar Quarter within [***] of the end of each Calendar Quarter in which the applicable Net Sales were recorded. Each Royalty report shall state on a Product-by-Product basis: (a) Net Sales of the Product in the applicable Calendar Quarter, including an itemized calculation of any deductions taken from gross sales to arrive at Net Sales for the applicable Calendar Quarter; (b) a calculation of the amount of the Royalty payment due on such Net Sales during the applicable Calendar Quarter; and (c) the amount of withholding taxes, if any, required by applicable Law to be deducted or withheld with respect to such Royalties. Royalties will be paid within [***] of the end of each Calendar Quarter in which the applicable Net Sales were recorded.

Section 3.6

Financial Records. Licensee will maintain, and shall cause its Affiliates and Sublicensees to maintain, records as are required to determine, in accordance with this Agreement, Net Sales and Royalties due under this Agreement. Licensee will maintain such records until the later of (a) three (3) years after the end of the period to which such records pertain, (b) the expiration of the applicable tax statute of limitations (or any extensions thereof), or (c) such longer period as may be required under applicable Law.

Section 3.7

Currency Conversion; Remittance. All payments due hereunder shall be converted into U.S. Dollars using the conversion rate for the relevant period as reported by Reuters Ltd (at ▇▇▇▇://▇▇▇▇▇▇▇.▇▇▇/▇▇▇▇▇▇▇/▇▇▇▇▇▇▇▇▇▇/▇▇▇▇▇) on the last Business Day of the relevant period. Licensee shall be solely responsible for taking any and all measures necessary to remit the payments due to TESARO hereunder outside the Licensed Territory.

Section 3.8

Late Payments. In the event that any payment due hereunder is not made when due, the payment shall accrue interest beginning on the day following the due date thereof, calculated at the annual rate of the sum of (a) [***] plus (b) the U.S. Prime Interest Rate quoted by The Wall Street Journal, Internet U.S. Edition at ▇▇▇▇://▇▇▇.▇▇▇.▇▇▇/▇▇▇▇▇▇/▇▇▇▇/▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇-▇▇▇▇▇.▇▇▇▇ on the date said payment is due, the interest being compounded on the last day of each Calendar Quarter; provided, however, that in no event shall said annual interest rate exceed the maximum rate permitted by applicable Law. Each such payment when made shall be accompanied by all interest so accrued. Said interest and the payment and acceptance thereof shall not negate or waive the right of any Party to seek any other remedy, legal or equitable, to which it may be entitled because of the delinquency of any payment including, but not limited to, termination of this Agreement as set forth in Article 9.

Section 3.9

Records and Audits. TESARO will have the right, once annually at its own expense, to have a nationally recognized, independent, certified public accounting firm selected by it review any such records of Licensee and its Affiliates and Sublicensees (the “Audited Party”) in the location(s) where such records are maintained by the Audited Party upon reasonable written notice (which shall be no less than thirty (30) days’ prior written notice) and during regular business hours and under obligations of strict confidence, for the sole purpose of verifying the

basis and accuracy of payments made under Section 3.3 within the thirty-six (36) month period preceding the date of the request for review. No Calendar Year will be subject to audit under this Section 3.9 more than once and an audit under this Section 3.9 shall not occur more than once in any Calendar Year; provided, that the foregoing limitation shall not limit TESARO from conducting additional audits in the event that TESARO should “have cause” to reasonably believe that this Agreement has been breached or that the initial audit was flawed on the basis of the materials provided to the auditors. Should such inspection lead to the discovery of a discrepancy to TESARO’s detriment, Licensee will, within twenty (20) days after the conclusion of such inspection, pay any undisputed amount of the discrepancy together with interest at the rate set forth in Section 3.8. TESARO will pay the full cost of the review unless the underpayment of amounts due to TESARO is greater than [***] of the amount due for the entire period being examined, in which case Licensee will pay the cost of such review. Any undisputed overpayment of Royalties by Licensee revealed by an examination will be paid by TESARO within twenty (20) days of the conclusion of such inspection. In no event will TESARO be responsible for late payment of withholding taxes or penalties related thereto, and Licensee shall indemnify and hold TESARO harmless for any such late payment or penalties.

Section 3.10

Taxes.

3.10.1 Withholding. In the event that any Law requires Licensee to deduct or withhold taxes with respect to any payment to be made by Licensee pursuant to this Agreement, Licensee will notify TESARO of such requirement prior to making the payment to TESARO and provide such assistance to TESARO, including the provision of such documentation as may be required by a tax authority, as may be reasonably necessary in TESARO’s efforts to claim an exemption from or reduction of such taxes. Licensee will, in accordance with such Law, deduct or withhold taxes from the amount due, remit such taxes to the appropriate tax authority when due, and furnish TESARO with proof of payment of such taxes within thirty (30) days following the payment. If taxes are paid to a tax authority, Licensee shall provide reasonable assistance to TESARO to obtain a refund of taxes withheld, or obtain a credit with respect to taxes paid. If no such refund or credit is received by TESARO within sixty (60) days of the date that such taxes are paid to a tax authority, Licensee will pay to TESARO within ten (10) days of written notice thereof by TESARO the difference between (a) the amount of the payment to be made by Licensee pursuant to this Agreement exclusive of the payment of such taxes, and (b) the amount of the payment that was actually paid to TESARO after such taxes are paid to a tax authority.

3.10.2 VAT. All payments due to TESARO from Licensee pursuant to this Agreement shall be paid net of any value-added tax (“VAT”) required to be paid by Licensee to tax authorities in the Licensed Territory (which, if applicable, shall be payable by Licensee upon receipt of a valid VAT invoice); provided, that Licensee shall use commercially reasonable efforts to assist TESARO to minimize and obtain all available exemptions from such VAT or other taxes. If Licensee is required to withhold and/or TESARO is required to report any such tax, Licensee

shall promptly provide TESARO with applicable receipts evidencing payment of such tax and other documentation reasonably requested by TESARO.

ARTICLE 4.

PATENT PROSECUTION, MAINTENANCE, & INFRINGEMENT

Section 4.1

Prosecution and Maintenance. As between the Parties, TESARO shall have the first right to file, prosecute and maintain all Patent Rights within the Licensed Patents in the Licensed Territory. All costs and expenses incurred in connection with such prosecution and maintenance activities shall be borne by TESARO, provided that Licensee shall reimburse TESARO for fifty percent (50%) of such costs and expenses within forty-five (45) days of an invoice therefor in the event that such prosecution and maintenance activities are necessary for the Development and/or Commercialization of the Licensed Compound and Product in the Licensed Territory. TESARO shall consult with Licensee and keep Licensee reasonably informed of the status of such Licensed Patents in the Licensed Territory. TESARO shall provide Licensee a reasonable opportunity to review and comment on all material filings and correspondence with patents offices with respect to the prosecution and maintenance of Licensed Patents in the Licensed Territory, and TESARO shall consider Licensee’s comments regarding such filings and correspondence in good faith. TESARO shall notify Licensee of any decision to cease prosecution and/or maintenance of any such Licensed Patents in the Licensed Territory and TESARO shall permit Licensee, to the extent permitted under the Upstream Agreements and at Licensee’s discretion and sole expense, to continue prosecution or maintenance of such Licensed Patent.

Section 4.2

Enforcement.

4.2.1 TESARO Enforcement. Each Party will notify the other promptly in writing when any Infringement of any Licensed Patent or Licensed Know-How by a Third Party (an “Infringer”) is uncovered or reasonably suspected in the Licensed Territory. TESARO shall have the first right to enforce any Patent Right within the Licensed Patents against any Infringement or alleged Infringement thereof in the Licensed Territory. TESARO may, at its sole option and expense, institute suit against any such Infringer or alleged Infringer and control and defend such suit. Licensee shall reasonably cooperate in any such litigation instituted by TESARO. Licensee shall have the right to participate in such action with counsel of its own choice and expense. TESARO shall not enter into any settlement of any claim described in this Section 4.2.1 that admits to the invalidity or unenforceability of the Licensed Patents, incurs any financial or other liability on the part of Licensee or requires an admission of liability, wrongdoing or fault on the part of Licensee, in each case without Licensee’s prior written consent, not to be unreasonably withheld, conditioned or delayed.

4.2.2 Licensee Enforcement. If TESARO elects not to enforce any Patent Right within the Licensed Patents against Infringement or alleged Infringement thereof in the Licensed Territory pursuant to Section 4.2.1, then it shall so notify Licensee in writing within thirty (30) days of receiving notice or otherwise becoming aware that an Infringement exists. If TESARO

does not notify Licensee in writing of its intent to initiate proceedings or take other appropriate action with respect to ceasing the applicable Infringement within such thirty (30) day period, Licensee may, to the extent permitted under the Upstream Agreements and at Licensee’s sole option and expense, institute suit against any such Infringer or alleged Infringer and control and defend such suit with counsel selected by Licensee. TESARO shall reasonably cooperate in any such litigation at Licensee’s request and expense, including by joining any such suit as a party. Licensee shall not enter into any settlement of any claim described in this Section 4.2.2 that admits to the invalidity or unenforceability of the Licensed Patents, incurs any financial or other liability on the part of TESARO or requires an admission of liability, wrongdoing or fault on the part of TESARO, in each case without TESARO’s prior written consent, not to be unreasonably withheld, conditioned or delayed.

4.2.3 Progress Reports. The Party initiating or defending any enforcement action described in this Section 4.2 shall keep the other Party reasonably informed of the progress of any such enforcement action.

4.2.4 Expenses; Recovery. Any damages, settlements or other monetary awards recovered in any such action shall first be applied to reimburse each Party’s costs and expenses in connection therewith. Any such recovery in excess of such costs and expenses shall be retained by the enforcing Party; provided, that if Licensee is the enforcing Party, then such recovery shall be deemed Net Sales and subject to Royalty payments to TESARO under Section 3.3.

Section 4.3

Defense of Third Party Claims. If either (a) the Product Manufactured or Commercialized by or under authority of Licensee becomes the subject of a Third Party’s claim or assertion of Infringement of a patent relating to the Manufacture or Commercialization of the Product in the Licensed Field in the Licensed Territory, or (b) if a declaratory judgment action is brought naming either Party as a defendant and alleging invalidity of any of the Licensed Patents, the Party first having notice of the claim or assertion shall promptly notify the other Party, and the Parties shall promptly confer to consider the claim or assertion and the appropriate course of action. Unless the Parties otherwise agree in writing, each Party shall have the right to defend itself against a suit that names it as a defendant (the “Defending Party”). None of the Parties shall enter into any settlement of any claim described in this Section 4.3 that admits to the invalidity or unenforceability of the Licensed Patents, incurs any financial or other liability on the part of the other Party or requires an admission of liability, wrongdoing or fault on the part of the other Party without such other Party’s prior written consent, not to be unreasonably withheld, conditioned or delayed. In any event, the other Party shall reasonably assist the Defending Party and cooperate in any such litigation at the Defending Party’s reasonable request and expense. If the Defending Party is deemed responsible in connection with any suit or claim subject to this Section 4.3, any resulting damages, settlement amounts and expenses shall be borne by the Defending Party. If both Parties are Defending Parties and are both deemed responsible in connection with any suit or

claim subject to this Section 4.3, any resulting damages, settlement amounts and expenses shall be borne by the Parties in proportion to their relative responsibility.

Section 4.4

Patent Marking. Licensee will ▇▇▇▇, and will cause its Affiliates and Sublicensees to ▇▇▇▇, the Product with all Licensed Patents in accordance with applicable Law, which marking obligation will continue for as long as (and only for as long as) required under applicable Law.

Each Party may at any time replace its JSC representatives upon written notice to the other Party. From time to time, the JSC may establish subcommittees to oversee particular projects or activities as it deems necessary or advisable, including with respect to the establishment between the Parties of a system for supply chain management and for the exchange of Product safety information, in each case directed to the Licensed Territory. Each subcommittee shall consist of an equal number of members from each Party with such expertise as the JSC determines is appropriate from time to time.

5.1.2 Chairperson of the JSC. Licensee shall select from its representatives a chairperson for the JSC, and Licensee may change its designated chairperson from time to time upon written notice to the other Party.

discussing at a high-level and exchanging relevant information relating to the Development and Commercialization activities for the Licensed Compound and Product undertaken by TESARO and its Affiliates outside of the Licensed Territory (i) to the extent relevant to the Development and Commercialization of the Licensed Compound and Product in the Licensed Territory, and (ii) to the extent that TESARO has the right to disclose such information to Licensee;

(e)

discussing at a high-level potential opportunities for coordination or collaboration between the Parties, with or without Third Parties, with respect to the Development and Commercialization of the Licensed Compound and Product that may be mutually beneficial to the Parties, in each case to the extent that each Party has the right to discuss such opportunities with the other Party; and

(f)

performing such other functions as appropriate to further the purposes of this Agreement, as expressly set forth in this Agreement or allocated to it by the Parties in writing by mutual agreement.

5.1.4 Meetings. The JSC shall meet at least one (1) time every six (6) months during any period in which any Development activities (except for any activities not necessary to obtain Marketing Approval, such as post-marketing surveillance activities or post-Marketing Approval clinical studies) in the Licensed Territory are ongoing and once (1) per year thereafter, and may meet at other times as mutually agreed by the Parties. The JSC meetings may occur in person or by telephone or videoconference; provided, that the Parties will hold one (1) in-person meeting per year at a location to be mutually agreed by the Parties. Each Party will bear its own costs associated with attending JSC meetings. Each Party may from time to time invite a reasonable number of participants, in addition to its representatives, to attend JSC meetings in a non-voting capacity.

If the Executive Officers cannot resolve such dispute within fifteen (15) Business Days, then (a) TESARO shall have final decision-making authority on any matter that may have an impact on or effect on the Development, Manufacture or Commercialization of the Licensed Compounds and Products outside of the Licensed Field and/or outside of the Licensed Territory, provided, however, that TESARO shall consider in good faith Licensee’s opinions if the matter would also have a non-trivial impact on or effect on the Development, Manufacture or Commercialization of the Licensed Compound or Products in the Licensed Territory, and (b) Licensee shall have final decision-making authority on any matter that is solely and exclusively related to the Licensed Territory.

5.1.6 Limitations on Authority of JSC. The JSC will have sole authority with respect to the responsibilities assigned to it in Section 5.1.3 and elsewhere in this Agreement.

Not later than thirty (30) days after December 31 of each Calendar Year, Licensee shall submit to the JSC an updated Development Plan for the pending Calendar Year. Such update shall take into account completion, commencement, changes in or cessation of Development activities not contemplated by the then-current Development Plan in sufficient detail to reflect the continued diligence of Licensee and shall reflect effort and resources consistent with other priority projects of Licensee. TESARO shall have the right to comment on such annual plan. In the event TESARO reasonably disagrees with the plan, Licensee shall consider in good faith TESARO’s comments for revising the plan. Notwithstanding anything to the contrary set forth in this Agreement, Licensee shall not have the right to use the Product in Development or Commercialization activities using a dosage amount

and/or dosage schedule that is not being used by TESARO in its Development and Commercialization activities for the Product in the TESARO Territory without TESARO’s prior written consent.

Section 5.3

Any failure by Licensee to comply with the obligations set forth in this Section 5.4 shall be deemed to be a material breach for which TESARO may exercise its termination rights under Article 9 and any other available remedies at law or in equity.

Section 5.5

Development Records. Licensee shall maintain complete and accurate records of all work conducted by or on behalf of Licensee in furtherance of the Development of the Licensed Compound and Product and all material results, data and developments made in conducting such activities.

In addition, if either Party is required to disclose Confidential Information of the other Party by regulation, Law or legal process, including by the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the

United States or of any stock exchange, such Party shall provide prior written notice and a copy of such intended disclosure to such other Party if possible under the circumstances, will consider in good faith the other Party’s comments, will disclose only such Confidential Information of such other Party as is required to be disclosed and will cooperate in the disclosing Party’s efforts to obtain a protective order or to limit the scope of the required disclosures.

Each Party shall remain responsible for any failure by its Affiliates, and its and its Affiliates’ respective employees, agents, consultants, advisors, contractors, Sublicensees and distributors, to treat such Confidential Information as required under this Section 8.1 (as if such Affiliates, employees, agents, consultants, advisors, contractors, Sublicensees and distributors were Parties directly bound to the requirements of this Section 8.1).

Notwithstanding anything to the contrary set forth in this Agreement, Licensee shall not have the right to, and shall ensure that its Affiliates and Sublicensees shall not, disclose (a) TESARO’s Confidential Information, including Licensed Know-How or information relating to the Licensed Patents, and any other information relating to the Licensed Compound or Product that is not part of the public domain, or (b) the terms of this Agreement, to [***] for any reason without the prior written consent of TESARO.

Notwithstanding the foregoing, without prior submission to or approval of the other Party, either Party may issue press releases or public announcements which incorporate information concerning this Agreement which information was included in a press release or public disclosure which was previously disclosed under the terms of this Agreement or which contains only non-material factual information regarding this Agreement.

Section 8.4

Relationship to the Confidentiality Agreement. This Agreement supersedes that certain Confidentiality Agreement by and between TESARO and Licensee dated April 17, 2015, as amended effective as of March 21, 2017; provided, however, that all “Confidential Information” disclosed or received by the Parties thereunder will be deemed “Confidential Information” hereunder and will be subject to the terms and conditions of this Agreement.

notice without any cure period. For clarity, termination of this Agreement under this Section 9.2.1 is not the exclusive right available to TESARO under this Agreement with respect to any uncured material breach by Licensee.

9.2.2 Termination for IP Challenge. TESARO will have the right to terminate this Agreement in full upon [***] advance written notice to Licensee in the event that (a) Licensee or any of its Affiliates or Sublicensees or any member of the Takeda Group directly or indirectly challenges in a legal or administrative proceeding anywhere in the world the patentability, enforceability or validity of (i) any Licensed Patents, or (ii) any other Patent Rights owned or Controlled by TESARO at any time during the Term that Cover (1) the compositions of matter of the Licensed Compound or Product, (2) methods or processes directed to the Manufacture of the Licensed Compound or Product, or (3) methods of use, administration or formulation of the Licensed Compound or Product (any such legal or administrative proceeding, a “Patent Challenge”), or (b) [***] directly or indirectly initiates a Patent Challenge and TESARO can establish by competent proof (which determination shall, in the event of any dispute between the Parties with respect thereto, be subject to arbitration in accordance with Section 10.4) that such Patent Challenge incorporates or is otherwise based in whole or in part on TESARO’s Confidential Information, including Licensed Know-How or information relating to the Licensed Patents or any other information relating to the Licensed Compound or Product that is not part of the public domain; provided, however, that TESARO will not have the right to terminate this Agreement under this Section 9.2.2 for any such Patent Challenge if such Patent Challenge is dismissed within [***] of TESARO’s notice to Licensee under this Section 9.2.2 and not thereafter continued.

9.2.3 Termination for Termination of Upstream Agreement. Subject to Section 6.6.2, and the second sentence of Section 6.6.1, if applicable , TESARO will have the right to terminate this Agreement in full upon written notice to Licensee upon the notice of the potential termination of any Upstream Agreement due to any action or inaction of the Licensee if such action or inaction is not cured prior to the expiration of any applicable cure-period in such Upstream Agreement.

9.2.4 Termination for Generic Product. TESARO shall have the right terminate this Agreement with respect to Japan upon [***] prior written notice to Licensee at any time after [***] of the date of the First Commercial Sale of a Generic Product in Japan; provided, that if at any time during the Term Licensee no longer has direct or indirect ownership of any voting or economic interest other than those arising from or in relation to the Pre-Effective Date Wholesaler Agreements in [***], Licensee shall have the right to provide TESARO written notice thereof, and upon receipt of such notice, TESARO’s right to terminate under this Section 9.2.4 shall no longer be effective for so long as Licensee continues not to have any direct or indirect ownership of any voting or such economic interest in [***].

Section 9.3

Termination by Licensee.

9.3.1 Breach. Licensee will have the right to terminate this Agreement in full upon delivery of written notice to TESARO in the event of any material breach by TESARO of any term or condition of this Agreement; provided, however, that such termination will not be effective if such breach has been cured within [***] after written notice thereof is given by Licensee to TESARO specifying the nature of the alleged breach. For clarity, termination of this Agreement under this Section 9.3.1 is not the exclusive remedy available to Licensee under this Agreement with respect to any uncured material breach by TESARO. If Licensee has the right to terminate this Agreement under this Section 9.3.1, then in lieu of exercising such right of termination, Licensee shall have the right, in its sole discretion and upon delivery of written notice to TESARO, to continue to maintain this Agreement in full force and effect, including all rights and licenses granted by TESARO to Licensee hereunder, provided that (a) Licensee continues to perform all of its obligations and comply with all of its covenants set forth in this Agreement, including all payment and other obligations arising under the Upstream Agreements, and (b) Licensee shall have the right to deposit into a Third Party escrow account any amounts payable directly by Licensee to TESARO under this Agreement, other than amounts that are due under the Upstream Agreements, that Licensee reasonably and in good faith estimates are consistent with the damages suffered by Licensee as a result of TESARO’s alleged uncured material breach pending resolution of any dispute relating to such alleged uncured material breach pursuant to Sections 10.3 and 10.4, with such amounts to be released to Licensee or TESARO, as applicable, promptly following resolution of such dispute.

9.3.2 Partial Termination. Licensee will have the right to terminate this Agreement on a country-by-country basis upon delivery of [***] prior written notice to TESARO.

Section 9.4

Termination Upon Bankruptcy. Either Party may terminate this Agreement if, at any time, any Insolvency Event occurs in relation to the other Party.

Section 9.5

Effects of Termination. Except as otherwise set forth in Section 9.6, upon early termination of this Agreement by either Party under this Article 9:

(a)

Licensee will responsibly wind-down, in accordance with accepted pharmaceutical industry norms and ethical practices, any on-going clinical studies for which it has responsibility hereunder in which patient dosing has commenced or, if reasonably practicable and requested by TESARO, Licensee shall, and shall cause its Affiliates and Sublicensees to, complete such trials. Licensee will be responsible for any costs associated with such wind-down. TESARO will pay all costs incurred by either Party to complete such studies should TESARO request that such studies be completed.

(b)

All sublicenses granted by Licensee pursuant to Section 2.2 will automatically terminate.

(c)

All rights and licenses granted by TESARO to Licensee in Article 2 will terminate, and Licensee and its Affiliates and Sublicensees will cease all use of Licensed Know-How and Licensed Patents and all Development, Manufacture and Commercialization of the Licensed Compound and Product.

(d)

All rights and licenses related to the Licensed Compound and Product in the Licensed Territory shall immediately revert to TESARO or to an Affiliate or Third Party designated by TESARO (each, a “Designee”).

(e)

All Marketing Approvals and other regulatory filings, documents and communications relating to the Product owned (in whole or in part) or otherwise controlled by Licensee or its Affiliates or Sublicensees, as such items exist as of the effective date of such termination (including all related completed and ongoing clinical studies) will be assigned to TESARO or its Designee and Licensee will provide to TESARO or its Designee one (1) copy of each of the foregoing and all documents contained in or referenced in any such items, together with the raw and summarized data for any clinical studies (and where reasonably available, electronic copies thereof). In the event of any failure to complete such assignment, Licensee hereby consents and grants to TESARO the right to access and reference (without any further action required on the part of Licensee, whose authorization to file this consent with any Regulatory Authority is hereby granted) any of the foregoing items.

(f)

Licensee hereby grants to TESARO and its Affiliates, and TESARO and its Affiliates will automatically have, a perpetual and irrevocable, royalty-free and fully paid-up, non-exclusive license, with the right to grant sublicenses through multiple tiers, under Know-How and Patent Rights that are Controlled by Licensee or any of its Affiliates and their respective Sublicensees that are necessary or useful to Development, Manufacture or Commercialize the Product in the Licensed Territory (such license effective only as of and after the effective date of such termination).

(g)

Upon TESARO’s request, Licensee will assign (or, if applicable, will cause its Affiliates or Sublicensees to assign) to TESARO all of Licensee’s (and such Affiliates’ and Sublicensees’) right, title and interest in and to any registered or unregistered trademarks or internet domain names that are specific to the Product (it being understood that the foregoing will not include any trademarks or internet domain names that contain the corporate or business name(s) of Licensee).

(h)

Licensee agrees (and shall cause its Affiliates and Sublicensees to so agree) to fully cooperate with TESARO and its Designee(s) to facilitate a smooth, orderly and prompt transition of the Development, Manufacture and Commercialization of the Licensed Compound and the Product in the Licensed Territory to TESARO and/or its Designee(s). Upon request by TESARO, Licensee shall transfer to TESARO or its Designee(s) any quantity of the Product in its possession as of the effective date of termination. If Licensee is, at the time of such termination of this Agreement, party to any Third Party contracts with respect to the Product, then it shall provide TESARO notice and (to the extent permitted by the terms thereof to do so), copies thereof. Licensee shall assign to TESARO any such contracts requested by TESARO, to the extent it has the right under such contract(s) to do so (and shall use commercially reasonable efforts to obtain any required consents to assign such contracts to TESARO). In addition, Licensee shall provide any cooperation reasonably requested by TESARO to ensure uninterrupted supply of the Product in the Licensed Territory.

(i)

Licensee agrees to take any other action necessary in order to ensure compliance with the terms of the Upstream Agreements.

For clarity, if Licensee terminates this Agreement as to a particular country or countries within the Licensed Territory in accordance with Section 9.3.2, then the foregoing provisions shall apply solely with respect to the country or countries that are subject to termination.

Section 9.6

Effect of Termination (Material Breach by TESARO). Upon any termination of this Agreement by Licensee pursuant to Section 9.3.1 resulting from a material breach of this Agreement by TESARO, then the provisions of Sections 9.5(a), (b) and (c) shall apply (except that compliance with subsection (a) shall be at the cost of TESARO), and Sections 9.5(d), (e), (f), (g), (h) and (i) shall have no effect. In addition if the material breach is a breach of Section 6.6.2 with respect to the Merck Agreement, then TESARO shall use reasonable efforts to cause Merck to enter into a direct license with Licensee for the Licensed Territory.

Section 9.7

Survival. The following provisions will survive termination or expiration of this Agreement: Sections 2.3, 2.8, 3.6, 3.8, 3.9, 3.10, 6.4, 6.5.1(d), 6.6.1, 9.5, 9.6 and this Section 9.7, and Articles 7, 8 and 10, as well as any applicable definitions in Article 1 and any other provisions which are expressed to survive termination or expiration or which are required to give effect to such termination or expiration. Termination or expiration of this Agreement will not relieve the Parties of any liability or obligation which accrued hereunder prior to the effective date of such termination or expiration nor preclude either Party from pursuing all rights and remedies it may have hereunder or at Law or in equity with respect to any breach of this Agreement.

ARTICLE 10.

MISCELLANEOUS

Section 10.1

Entire Agreement; Amendment. This Agreement and all Exhibits attached to this Agreement constitute the entire agreement between the Parties as to the subject matter hereof. All prior and contemporaneous negotiations, representations, warranties, agreements, statements, promises and understandings with respect to the subject matter of this Agreement are hereby superseded and merged into, extinguished by and completely expressed by this Agreement. None of the Parties shall be bound by or charged with any written or oral agreements, representations, warranties, statements, promises or understandings not specifically set forth in this Agreement. No amendment, supplement or other modification to any provision of this Agreement shall be binding unless in writing and signed by all Parties.

Section 10.2

Independent Contractors. The relationship between Licensee and TESARO created by this Agreement is solely that of independent contractors. This Agreement does not create any agency, distributorship, employee-employer, partnership, joint venture or similar business relationship between the Parties. Neither Party is a legal representative of the other Party, and neither Party can assume or create any obligation, representation, warranty or guarantee, express or implied, on behalf of the other Party for any purpose whatsoever.

Section 10.3

Informal Discussions. Except as otherwise provided herein, in the event of any controversy or claim arising out of or relating to this Agreement, or the rights or obligations of the Parties hereunder, or the relationship between the Parties with respect to the Licensed Compounds or Products, the Parties shall first try to settle their differences amicably between themselves. Either Party may initiate such informal dispute resolution by sending written notice of the dispute to the other Party, and within thirty (30) days after such notice appropriate representatives of the Parties shall meet for attempted resolution by good faith negotiations. If such representatives are unable to resolve promptly such disputed matter within the said thirty (30) days, either Party may refer the matter by written notice to the Executive Officers for discussion and resolution. If such Executive Officers are unable to resolve such dispute within thirty (30) days of such written notice, either Party may initiate arbitration proceedings in accordance with the provisions of Section 10.4.

Section 10.4

Arbitration. All disputes arising out of or relating to this Agreement, or the rights or obligations of the Parties hereunder, or relating in any way to the relationship between the Parties with respect to the Licensed Compounds or Products, shall be finally and exclusively settled by arbitration by a panel of three (3) arbitrators, provided such dispute is not an “Excluded Claim.” As used in this Section, the phrase “Excluded Claim” shall mean a dispute, controversy or claim that concerns (a) the validity or Infringement of a patent, trademark or copyright (which shall not, for clarity, include any dispute, controversy or claim as to whether TESARO has established the relevant competent proof referenced in Section 9.2.2), (b) any antitrust, anti-monopoly or competition Law or regulation, whether or not statutory, or (c) any matter for which a Party has final decision-making authority under Section 5.1.5.

10.4.1 The arbitration proceeding shall be conducted under the Commercial Arbitration Rules of the American Arbitration Association (“AAA”) with such proceedings to be held in New York, New York, United States. The arbitrators will apply the substantive Law of the State of New York. In all cases, the arbitration proceedings shall be conducted in the English language, and all documents that are submitted in the proceeding shall be in the English language. Judgment upon the award rendered by arbitration may be issued and enforced by any court having competent jurisdiction.

10.4.2 If a Party intends to begin an arbitration to resolve a dispute, such Party shall provide written notice to the other Party, informing the other Party of such intention and any statement of claim required under the applicable arbitration rules. Within twenty (20) Business Days after its receipt of such notice, the other Party shall, by written notice to the Party initiating arbitration, add any additional issues to be resolved that would be considered mandatory counterclaims under New York Law. For clarity, the resolution of any disputes regarding such counterclaims shall be conducted in the same proceedings as the initial claims.

10.4.3 Within forty-five (45) days following the receipt of the notice of arbitration, the Party referring the matter to arbitration shall appoint an arbitrator and promptly notify the other Party of such appointment. The other Party shall, upon receiving such notice, appoint a second arbitrator within twenty one (21) days, and the two (2) arbitrators shall, within fifteen (15) days of the appointment of the second arbitrator, agree on the appointment of a third arbitrator who will act with them and be the chairperson of the arbitration panel. In the event that either Party shall fail to appoint an arbitrator within thirty (30) days after the commencement of the arbitration proceeding, the arbitrator shall be appointed by the AAA. In the event of the failure of the two (2) arbitrators to agree within sixty (60) days after the commencement of the arbitration proceeding to appoint the chairperson, the chairperson shall also be appointed by the AAA.

10.4.4 All of the arbitrators shall have significant legal or business experience in pharmaceutical licensing matters. The arbitrators shall not be employees, directors or shareholders of either Party or any of their Affiliates.

10.4.5 Each Party shall have the right to be represented by counsel throughout the arbitration proceedings.

10.4.6 To the extent possible, the arbitration hearings and award will be maintained in confidence.

10.4.7 In any arbitration pursuant to this Agreement, the award or decision shall be rendered by a majority of the members of the panel provided for herein, with each member having one (1) vote. The arbitrators shall render a written decision with their resolution of the dispute that shall set forth in reasonable detail the facts of the dispute and the

reasons for their decision. The decision of the arbitrators shall be final and non-appealable and binding on the Parties.

Section 10.5

Injunctive Relief. By agreeing to arbitration, the Parties do not intend to deprive any competent court of such court’s jurisdiction to issue a pre-arbitral injunction, pre-arbitral attachment or other order in aid of the arbitration proceedings and the enforcement of any award or judgment. Without prejudice to such provisional remedies in aid of arbitration as may be available under the jurisdiction of a national court, the court of arbitration shall have full authority to grant provisional remedies and to award damages for failure of any Party to respect the court of arbitration’s order to that effect.

Section 10.6

Expenses of Arbitration and Expert Determination. Each Party shall bear its own attorneys’ fees, costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the arbitrators; provided, however, that the arbitrators shall be authorized to determine whether a Party is the prevailing Party, and if so, to award to that prevailing Party reimbursement for its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges and travel expenses). Absent the filing of an application to correct or vacate the arbitration award as permitted by applicable Law, each Party shall fully perform and satisfy the arbitration award within fifteen (15) days of the service of the award.

Section 10.7

Notice. All notices or communications required or permitted to be given by either Party hereunder shall be deemed sufficiently given if mailed by registered mail or certified mail, return receipt requested, or sent by overnight courier, such as Federal Express, to the other Party at its respective address set forth below or to such other address as notified by the other Party from time to time pursuant to this Section 10.7. Mailed notices shall be deemed to be received on the third (3rd) Business Day following the date of mailing. Notices sent by overnight courier shall be deemed received the following Business Day.

Section 10.8

Governing Law. This Agreement and any dispute arising from the performance of breach hereof shall be governed by and construed and enforced in accordance with the Laws of the State of New York without reference to conflicts of Laws principles which would direct the application of the Laws of another jurisdiction.

Section 10.11

Successors and Assigns. Neither this Agreement nor any of the rights or obligations created herein, may be assigned by either Party, in whole or in part, without the prior written consent of the other Party, except that either Party shall be free to assign this Agreement (a) as a whole or in part without consent to an Affiliate, or (b) as a whole without consent in connection with any merger or sale of such Party or sale of all or substantially all of the assets of such Party related to the business-line or division of that Party that is the beneficiary of the rights and licenses granted under this Agreement; provided, that Licensee may not assign this Agreement in any circumstance to a Post-Execution Affiliate engaged in Competing Activities. This Agreement shall bind and inure to the benefit of the successors and permitted assigns of the Parties hereto. Any assignment of this Agreement in contravention of this Section 10.11 shall be null and void.

Section 10.12

Waivers. A Party’s consent to or waiver, express or implied, of the other Party’s breach of its obligations hereunder shall not be deemed to be or construed as a consent to or waiver of any other breach of the same or any other obligations of such breaching Party. A Party’s failure to complain of any act, or failure to act, by the other Party, to declare the other Party in default, to insist upon the strict performance of any obligation or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof, no matter how long such failure continues, shall not constitute a waiver by such Party of its rights hereunder, of any such breach, or of any other obligation or condition. A Party’s consent in any one instance shall not limit or waive the necessity to obtain such Party’s consent in any future instance and in any event no consent or waiver shall be effective for any purpose hereunder unless such consent or waiver is in writing and signed by the Party granting such consent or waiver.

Section 10.13

No Third Party Beneficiaries. Except as expressly set forth herein, nothing in this Agreement shall be construed as giving any Person, other than the Parties hereto and their successors and permitted assigns, any right, remedy or claim under or in respect of this Agreement or any provision hereof.

The language in all parts of this Agreement shall be deemed to be the language mutually chosen by the Parties. The Parties and their counsel have cooperated in the drafting and preparation of this Agreement, and this Agreement therefore shall not be construed against any Party by virtue of its role as the drafter thereof.

For the avoidance of doubt and by way of example, if the Product is first approved for 2nd-line therapy of ovarian cancer and then the indication is extended to 1st-line therapy of ovarian cancer, only the filing and approval for the 2nd-line therapy of ovarian cancer shall be deemed to be the triggering event for the Milestone Payment for such non-prostate indication.
