4.2 Development Plan.  The Development of the Compound and Products under this Agreement shall be conducted pursuant to a comprehensive written global Development plan (the “Development Plan”) as set forth in this Article 4, which shall be incorporated by reference as part of this Agreement.  The Development Plan will include Clinical Trials that the Parties have committed to conducting ([*]),  as well as Clinical Trials that may be decided by the JSC [*].  The Development Plan may also include any other Development activities approved by the JSC in accordance with Article ‎3.  As of the Effective Date, the Parties have agreed upon an initial Development Plan and the associated Development Budget, attached to this Agreement as Exhibit C.  If the terms of the Development Plan contradict, or create inconsistencies or ambiguities with, the terms of this Agreement, then the terms of this Agreement shall govern.

(a) Territory-Specific Development Work.  Each Party shall be solely responsible for all Development work with respect to Development activities that are exclusively for the benefit of the countries within such Party’s territory, including (i) any and all Development activities required or recommended specifically by a Regulatory Authority of a Party’s territory solely for the benefit of such Party’s territory (e.g., additional Clinical Trials or CMC-related activities), and (ii) any and all Development activities required for any Pricing and Reimbursement Approval in such Party’s territory (but that are not required for the MAA Approval in such territory).  The Development work set forth in this Section ‎4.2(a) pertaining to the Kissei Territory shall be deemed the “Kissei Only Development Work” and the Development work set forth in this Section ‎4.2(a) pertaining to the Rigel Territory shall be deemed the “Rigel Only Development Work”.  Without limiting the generality of the foregoing, any Phase 3 Clinical Trial required to obtain MAA Approval of the Product for IgAN, ITP, or AIHA in the Kissei Territory that is not required to obtain MAA Approval of the Product in the Rigel Territory shall be deemed Kissei Only Development Work and Kissei shall be solely responsible for conducting such Phase 3 Clinical Trial(s) at its expense as part of the Development Plan and in accordance with the terms of this Agreement.

(b) Kissei Territory Development Work.  Without limiting the generality of the foregoing, Kissei shall be responsible for conducting a Phase 3 Clinical Trial in Japan for the Product for (i) ITP, (ii) AIHA, and (iii) IgAN.  The Development Plan shall set forth the timeline and details ([*]) of such Phase 3 Clinical Trials, which shall be deemed Kissei Only Development Work, as well as all other preclinical and clinical Development activities to be conducted by Kissei as necessary to generate Data sufficient to meet the requirements of the PMDA, CFDA, and other Regulatory Authorities in the Kissei Territory for MAA Approval of the Compound and Products for ITP, AIHA, and IgAN.  If Kissei [*], Kissei shall present to the JSC [*] and the JSC shall review and approve any decision to [*] Clinical Trial.

(c) Joint Development Work.  The Development Plan shall set forth the timeline and details ([*]) of all preclinical and clinical Development activities to be conducted jointly by the Parties as necessary to generate Data sufficient to meet the common requirements of the FDA, the PMDA, and other Regulatory Authorities agreed upon in writing by the Parties for MAA Approval of the Compound and Products for Indications agreed upon in writing by the Parties (“Joint Development Work”).  Notwithstanding Section ‎4.2(b), the Parties shall discuss, through the JSC, potentially conducting Phase 3 Clinical Trials for IgAN so as to meet the common requirements of the FDA and PMDA and, if the JSC agrees to a protocol and study plan for such a  Phase 3 Clinical Trial that meets the foregoing requirements, such Phase 3 Clinical Trial shall be deemed Joint Development Work.  For clarity, if the

JSC is unable to timely agree upon a protocol and study plan for such Phase 3 Clinical Trial, Rigel shall have the right (but not the obligation) to conduct a Phase 3 Clinical Trial for the Product for IgAN, as the case may be, in the Rigel Territory as Rigel Only Development Work, and Kissei shall have (i) the right (but not the obligation) to conduct a Phase 3 Clinical Trial for the Product in IgAN in the Kissei Territory as Kissei Only Development Work as contemplated in Section ‎4.2(b) and (ii) the obligation to conduct a Phase 3 Clinical Trial for AIHA for the Product in the Kissei Territory as Kissei Only Development Work unless Kissei presents to Rigel via the JSC [*] for not conducting such Clinical Trial ([*]).

4.3 Independent Work. 

(a) If either Party (the “Developing Party”) is interested in pursuing additional Development work on a Product ([*]) for the benefit of (a) the Rigel Territory or Kissei Territory in the case of Rigel, or (b) the Kissei Territory in the case of Kissei, in each case beyond what is set forth in the then-current Development Plan, then such Party shall provide the other Party (the “Non-Developing Party”) with a written detailed plan and budget for such additional work (the “Proposal”).  Within [*] after the Non-Developing Party’s receipt of the Proposal, the JSC (or JDC or other delegated team) shall meet to review the Proposal and permit the Non-Developing Party an opportunity to ask questions and request additional information from the Developing Party related to the Proposal, including whether such Proposal is reasonably likely to have any adverse effect on the Development or Commercialization of the Product in the Non-Developing Party’s territory.  No work under any Proposal shall proceed unless and until the JSC determines in its reasonable discretion that such Proposal is not likely to adversely affect the Development or Commercialization of the Product in the Non-Developing Party’s territory, and following each such determination, if any, the JSC shall incorporate such additional Development work and the corresponding budget into the Development Plan (the “Newly-Proposed Development Work”).  For any Newly-Proposed Development Work, the Non-Developing Party may elect, at its discretion, to share the Development Costs with respect to such Development work under Section ‎8.2(a), and following such election such Newly-Proposed Development Work shall be Joint Development Work, but subject to the cost-sharing terms set forth in Section ‎8.2(a).    

(b) If the Non-Developing Party elects to not pursue the Newly-Proposed Development Work jointly with the Developing Party and does not share the Development Costs with respect to such Development work as provided under Section ‎8.2(a), such Development work shall be deemed the “Independent Work” of the Developing Party and the Developing Party may pursue such work subject to the remainder of this Section ‎4.3, and the Development Costs with respect thereto shall be Independent Work Costs subject to Section ‎8.2(b).  Following the amendment of the Development Plan by the JSC to include any Newly-Proposed Development Work that is Independent Work, the Developing Party may conduct such Independent Work, provided that: (x) it shall do so in accordance with the amended Development Plan, (y) it shall provide updates to the JSC with respect to such Independent Work at each regularly scheduled JSC meeting, and (z) neither Party shall conduct any Independent Work in a manner that would have, or would be reasonably expected to have, any adverse effect on the Development or Commercialization of the Product in either Party’s territory.  Rigel shall have the right to conduct Development activities in the Kissei Territory as Independent Work, such as the Development of the Product to support Regulatory

Approval in any particular Indication in any country or region in the Kissei Territory, in the event Kissei does not wish to conduct such activities as part of the Joint Development Work.  Kissei shall have the right to conduct, as Independent Work but subject to the approval of the JSC, Development activities in the Rigel Territory solely as needed to support Regulatory Approval in the Kissei Territory in the event Rigel does not wish to conduct such activities as part of the Joint Development Work and such Development activities cannot, based on the determination of the JSC, be reasonably carried out in the Kissei Territory [*].  In the event either Party conducts such Independent Work in the other Party’s territory, the Party conducting such Independent Work shall coordinate and consult with the Non-Developing Party (and any of such Non-Developing Party’s (sub)licensee(s) for the applicable country or region in which such Independent Work is proposed to be conducted, subject to such Non-Developing Party’s agreement with such (sub)licensee(s)), including with respect to communication with Regulatory Authorities and clinical trial sites selection and management. And in no event may the Developing Party proposing to conduct such Independent Work in a particular country or region in the Non-Developing Party’s territory carry out a Clinical Trial in such country or region for the same Indication for which such Non-Developing Party (either by itself or through its Affiliate or actual or potential (sub)licensee) is conducting or is actively planning to conduct in such country or region.

(c) Notwithstanding the foregoing, Rigel shall have the right to conduct any Development activities with respect to the Compound or Product in the Rigel Territory outside the scope of the Development Plan.  Such Development activities shall be: (i) deemed Rigel Only Development Work for the purpose of this Agreement, (ii) at Rigel’s sole cost and expense pursuant to Section 4.5(a), and (iii) be subject to Section 4.7(d) such that Kissei shall have the right of reference to the data generated in such Development activities without any reimbursement obligation to Rigel.

(a) Shared Development Costs.  With respect to Joint Development Work, Kissei shall bear one hundred percent (100%) of all Development Costs (including Allowable Increases) for Joint Development Work pertaining to the Kissei Territory and Rigel shall bear one hundred percent (100%) of all Development Costs (including Allowable Increases) for Joint Development Work pertaining to the Rigel Territory, in each case as set forth in the Development Plan.  No later than [*] after the beginning of each Calendar Quarter during which a Party will perform any Joint Development Work in such Calendar Quarter, such Party shall submit to the other Party a statement setting forth the Development Costs incurred, including the other Party’s share (calculated in accordance with the foregoing sentence) of (i) estimated Development Costs for the then current quarter; (ii) variances from prior invoiced estimates and actual Development Costs; and (iii) Development Costs incurred by or on account of such Party in the past quarter not previously invoiced.  Such invoice shall include a reasonably detailed report for such Development Costs, including supporting documents.  The other Party shall pay the amount invoiced within [*] after the receipt of the invoice, subject to the other Party’s right to audit the invoicing Party’s records and books related to such costs as provided in Section ‎9.4.  If both Parties will perform Joint Development Work under the Development Plan in such Calendar Quarter, the Parties shall consolidate the payments for such Calendar Quarter into a single payment from one Party to the other Party, as applicable.

(b) Independent Work.    

(i) Except as set forth below in this Section ‎8.2(b), each Party shall bear all of the Development Costs incurred by or on account of such Party in performing its own Independent Work (the “Independent Work Costs”). After the completion of such Independent Work, such Party shall provide the other Party with a report of such Independent Work Costs.  If a Party desires to submit any portion of the Data resulting from any Independent Work conducted by the other Party and related Regulatory Filings generated by the other Party to support Regulatory Approval in its own territory, then such Party shall notify the other Party in writing at any time following the completion of such Independent Work. Within [*] after its receipt of such notice, the Party conducting or having conducted such Independent Work shall submit to the other Party a reasonably detailed invoice setting forth [*] the Independent Work Costs that such other Party would have incurred in connection with the generation of such Data if such Independent Work Costs were Development Costs shared jointly by the Parties as set forth in Section ‎8.2(a) (e.g., with respect to Independent Work conducted by Rigel, Kissei would be responsible for [*] any Independent Work Costs pertaining to the Kissei Territory).  Should there be no Independent Work Costs pertaining to the Kissei Territory for Rigel Independent Work and Kissei wishes to reference the Data from such Independent

Work for regulatory purposes in the Kissei Territory, then the Parties shall negotiate in good faith a percentage reimbursement of Rigel’s Independent Work Costs for such Independent Work.  If Kissei decides to use such Data to support Regulatory Approval of the Product in the Kissei Territory, then Kissei shall notify Rigel in writing and pay the amount invoiced by Rigel within [*] after the receipt of such invoice.

(ii) Notwithstanding the foregoing Section ‎8.2(b)(i), if Rigel conducts Independent Work in the Kissei Territory and obtains MAA Approval of the Product in any country in the Kissei Territory for any new Indication or new formulation of the Product as a result of such Independent Work, Kissei shall be obligated to reimburse Rigel for the greater of: (A) [*] any of Rigel’s Independent Work Costs for Development activities specifically performed to support the MAA filing in such country in the Kissei Territory; and (B) the pro-rata share of the total costs for the global Development of such Product for such Indication allocated to the country(ies) or region(s) in the Kissei Territory [*].  Upon Rigel’s receipt of such payment in full, Kissei shall have the right and obligation to Commercialize, itself or through a Sublicensee, such Product under such MAA Approval.  In addition, Kissei shall pay to Rigel the milestone payment(s) set forth in Section ‎8.3 triggered by such Product for such Indication in such country that would have been paid if such Development and regulatory activities were conducted by Kissei (or its Affiliate or Sublicensee) instead of Rigel (i.e., MAA submission and approval milestone payments for such Indication) (the “Missed Milestone Payments”), by making a [*] payment to Rigel that is equal to [*] (the “Milestone Catch-Up Payment”) until the total amount of such Milestone Catch-Up Payments made by Kissei in aggregate equals the amount of such Missed Milestone Payments.  For clarity, such Milestone Catch-Up Payments shall commence with [*] and shall be in addition to the Transfer Price payments for such Product paid by Kissei to Rigel under Section 8.5(a) and ends at the end of the Commercialization Term.

(c) Internal Development Cost.  Each Party shall record and calculate its internal Development Costs on an FTE basis at the applicable FTE Rate.

8.3 Development Milestone Payments.

(a) Development Milestones.  Subject to the remainder of this Section ‎8.3, Kissei shall pay to Rigel the one-time, non-refundable, non-creditable payments set forth in the table below upon the achievement of the applicable milestone event (whether by or on behalf of Kissei or its Affiliates or Sublicensees).

8.4 Sales Milestones Payments.    

(a) Kissei shall pay to Rigel the one-time, non-refundable, non-creditable payments set forth in the table below when the aggregated Net Sales of all Products [*] in any Calendar Year first reach the values indicated in the table below.  For clarity, each payment in this Section ‎8.4 shall be payable once only upon first achievement of the applicable milestone event, regardless  of the number of times such milestone is subsequently achieved.

8.5 Transfer Price.

(a) Transfer Price During the Commercialization Term. 

(i) In consideration for the Drug Product provided by Rigel to Kissei for Commercial use, Kissei shall pay to Rigel a provisional transfer price (the “Transfer Price”) equal to the percentage rates set forth

in the table below (the “Transfer Price Rate”) for all Product provided to Kissei for sale by or on behalf of Kissei or its Affiliates or Sublicensees during the Commercialization Term.

(ii) Notwithstanding the foregoing, on a country-by-country or region-by-region basis, if [*] a unit of Product exceeds an amount equal to [*] for such unit of Product in such country or region (the “Base Percent”), the Transfer Price Rate set forth in Section ‎8.5(a)(i) for such unit of Product in such country or region shall be adjusted accordingly: for [*] the Base Percent, the Transfer Price Rate set forth in Section 8.5(a)‎(i) shall be increased by [*], provided, however, that in no event shall the Transfer Price Rate exceed [*].  By way of example only, [*] for such Product in a particular country, the Transfer Price Rate for such Product in such country shall be equal to [*] for portions of Net Sales less than or equal to [*] for portions of Net Sales greater than [*], but less than [*], and [*] for portions of Net Sales greater than [*].  For clarity, the Transfer Price Rate in this Section 8.5(a) shall apply to the units of Products sold for the period during which such Transfer Price Rate(s) applies, regardless of when such Products are manufactured and/or supplied to Kissei.  If, during the Commercialization Term, the Transfer Price for the Product [*] for such Product falls below an amount equal to [*] for such Product, the Parties shall discuss in good faith a modification in the Transfer Price Rate(s) for such Product [*].

(b) Transfer Price During the Extended Commercialization Term.  In consideration for the Drug Product provided by Rigel to Kissei for Commercial use, Kissei shall pay to Rigel a Transfer Price equal to [*] for all Product manufactured for sale by or on behalf of Kissei or its Affiliates or Sublicensees during the Extended Commercialization Term.  For clarity, Kissei shall have the right to obtain other source(s) of supply for the Compound and Drug Product and to conclude a contract with Rigel’s manufacturers directly after the Commercialization Term.

(c) Transfer Price Payments During the Commercialization Term. 

(i) Estimated Price.  No later than [*] the first Product in the first Indication in the Kissei Territory, Kissei shall calculate and report to Rigel its good-faith, estimated average per unit Net Sales price for the Product in the Kissei Territory (the “ENS”) until the end of that Calendar Year.  Thereafter, no later than [*] before the beginning of each Calendar Year, Kissei shall calculate and report to Rigel the ENS for the Product in the Kissei Territory for such Calendar Year.  The ENS shall be calculated and reported by Kissei on a country-by-country basis.    

(ii) Initial Payment.  For each unit of Drug Product delivered to Kissei in a Calendar Quarter during the Commercialization Term, Kissei shall pay to Rigel an amount equal to the Transfer Price Rate of the applicable ENS for Drug Product for such Calendar Quarter, which amount shall be paid within [*] Kissei receives Rigel’s invoice for such quantity of Drug Product.    

(iii) Actual Price and True Up.  Within [*] after the end of each Calendar Quarter during the Commercialization Term, Kissei shall calculate and report to Rigel in writing the actual average per unit Net Sales price for the Product in the Kissei Territory in such Calendar Quarter (the “ANS”) on a country-by-country basis.  The ANS shall be calculated by dividing the Net Sales for such Calendar Quarter in a country by the number of units of Product sold by Kissei that constitutes the Net Sales for such period in such country.  Within [*] after Kissei’s report of the ANS for a Calendar Quarter:

(1) if the ANS is greater than the ENS for a country, then Kissei shall pay to Rigel a true up payment equal to the applicable Transfer Price Rate multiplied by (ANS – ENS) for each unit of Drug Product ordered by Kissei and delivered by Rigel for Commercial use in such country during such Calendar Quarter; and

(2) if the ANS is less than the ENS for a country, then Rigel shall issue a credit to Kissei equal to the applicable Transfer Price Rate multiplied by (ENS – ANS) for each unit of such Drug Product ordered by Kissei and delivered by Rigel for Commercial use in such country during such Calendar Quarter.

(d) Transfer Price Adjustments During the Commercialization Term. 

(i) During the Commercialization Term, if one or more Generic Products to a Product is sold in any country in the Kissei Territory for such Product in such country, and such Generic Products [*] during such Calendar Quarter, the Transfer Price Rates provided in Section ‎8.5(a) for such Product shall be reduced in such country by [*] for such Calendar Quarter.

(ii) During the Commercialization Term, if it is necessary for Kissei to obtain a license from a Third Party under any Patent in a particular country in the Kissei Territory in order to sell a Product in such country and Kissei obtains such a license, Kissei may deduct from the Transfer Price that would otherwise have been due pursuant to Section ‎8.5(a) with respect to Net Sales of such Product in such country in a particular Calendar Quarter an amount equal to [*] paid by Kissei to such Third Party pursuant to such license on account of the sale of such Product in such country during such Calendar Quarter.  For clarity, [*].

(iii) Notwithstanding the foregoing, during any Calendar Quarter in the Commercialization Term for a Product in a country, the operation of subsection (i) and (ii) above, individually or in combination, shall not reduce by more than [*] the Transfer Price that would otherwise have been due under Section ‎8.5(a) with respect to Net Sales of such Product in such country during such Calendar Quarter.  Kissei [*].

(e) Transfer Price Payments During the Extended Commercialization Term.  The Transfer Price payable by Kissei to Rigel for each unit of Drug Product delivered to Kissei during the Extended Commercialization Term under Section ‎8.5(b) shall be due within [*] after Kissei’s receipt from Rigel of an invoice for such Drug Product.  For clarity, such payments shall not be subject to any offsets or reductions whatsoever, including those set forth in Section ‎8.5(d). 

9.

Payment; Records; Audits

9.1 Payment; Reports.  All Transfer Price payments due under Section ‎8.5 shall be accompanied by a report setting forth, on a country-by-country basis, Net Sales of the Products by Kissei and its Affiliates and Sublicensees in the Kissei Territory in sufficient detail to permit confirmation of the accuracy of the Transfer Price payment made, including, for each country, the number of Products sold, the Gross Sales and Net Sales of Products, including the deductions from Gross Sales to arrive at Net Sales, the Transfer Price payable, the method used to calculate the Transfer Price, the exchange rates used, any adjustments to the Transfer Price Rate in accordance with Section ‎8.5(d), and whether any Net Sales milestone under Section ‎8.4 has been achieved.  Prior to the First Commercial Sale of the Product in the Kissei Territory, the Parties will agree on the form of Transfer Price report. 

Kissei shall submit a single report for all Net Sales during a Calendar Year, including all of Kissei’s and its Affiliates’ and Sublicensees’ Net Sales, but shall separately identify the Net Sales and other information applicable to each entity.

9.2 Exchange Rate; Manner and Place of Payment.  All references to dollars and “$” herein shall refer to U.S. dollars.  All payments hereunder shall be payable in U.S. dollars.  When conversion of Net Sales from any currency other than U.S. dollars is required, such conversion shall be at the exchange rate equal to the conversion rate for the U.S. dollar for the currency of the country in which the applicable Net Sales were made as published by [*].  All payments owed under this Agreement shall be made by wire transfer in immediately available funds to a bank and account designated in writing by Rigel, unless otherwise specified in writing by Rigel. 

9.3 Taxes. 

(a) Taxes on Income.  Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the activities of the Parties under this Agreement. 

(b) Tax Cooperation.  The Parties agree to cooperate with one another and use reasonable efforts to avoid or reduce tax withholding or similar obligations in respect of the milestone payments, Transfer Price payments, and other payments made by Kissei to Rigel under this Agreement.  To the extent that Kissei is required by Applicable Laws to deduct and withhold taxes on any payment to Rigel, Kissei shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to Rigel an official tax certificate or other evidence of such payment sufficient to enable Rigel to claim such payment of taxes.  Rigel shall provide Kissei any tax forms that may be reasonably necessary in order for Kissei to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty, to the extent legally able to do so.  Rigel shall use reasonable efforts to provide any such tax forms to Kissei in advance of the due date.  Kissei shall provide Rigel with reasonable assistance to enable the recovery, as permitted by Applicable Laws, of withholding taxes or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of Rigel.  Kissei shall have the right to deduct any such tax, levy, or charge actually paid from payment due to Rigel.  Each Party agrees to assist the other Party in claiming exemption from such deductions or withholdings under double taxation or similar agreement or treaty from time to time in force and in minimizing the amount required to be so withheld or deducted.

(c) Taxes Resulting From Kissei’s Action.  If a Party takes any action of its own discretion (not required by a Regulatory Authority), including any assignment, sublicense, change of place of incorporation, or failure to comply with Applicable Laws or filing or record retention requirements, which results in a withholding or deduction obligation (“Withholding Tax Action”), then such Party shall pay the sum associated with such Withholding Tax Action.  For clarity, if Kissei undertakes a Withholding Tax Action, then the sum payable by Kissei (in respect of which such deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that Rigel receives a sum equal to the sum which it would have received had no such Withholding Tax Action occurred.  Otherwise, the sum payable by Kissei (in respect of which such deduction or withholding is required to be made) shall be made to Rigel after deduction of the amount required to be so withheld or deducted.  If a change in Applicable Laws results in a withholding or deduction obligation absent either Party taking a Withholding Tax Action, then the amount of such withholding or deduction obligation shall be paid by Kissei to the applicable Governmental Authority on behalf of Rigel, provided that Kissei shall use reasonable efforts to assist Rigel in minimizing or recovering such withholding or deduction obligation.  The Parties shall use commercially reasonable efforts to invoke the application of any applicable bilateral income tax treaty that would reduce or eliminate otherwise applicable taxes with respect to payments payable pursuant to this Agreement.

9.4 Records; Audit.  Each Party shall maintain complete and accurate records in sufficient detail in relation to this Agreement to permit the other Party to confirm the accuracy of the amount of Development Costs and the Cost of Goods to be reimbursed or shared, achievement of Net Sales milestones, and the amount of Transfer Price and other payments payable under this Agreement.  Each Party will keep such books and records for at least [*] following the Calendar Year to which they pertain.  Upon reasonable prior notice, such records shall be inspected during regular business hours at such place or places where such records are customarily kept by an independent certified public accountant (the “Auditor”) selected by the auditing Party and reasonably acceptable to the audited

Party for the sole purpose of verifying for the auditing Party the accuracy of the financial reports furnished by the audited Party pursuant to this Agreement or of any payments made, or required to be made, by or to the audited Party pursuant to this Agreement.  Before beginning its audit, the Auditor shall execute an undertaking acceptable to each Party by which the Auditor agrees to keep confidential all information reviewed during the audit.  Such audits may occur no more often than [*] each Calendar Year and not more frequently than [*] with respect to records covering any specific period of time.  Each Party shall only be entitled to audit the books and records from the [*] prior to the Calendar Year in which the audit request is made.  Such auditor shall not disclose the audited Party’s Confidential Information to the auditing Party, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by the audited Party or the amount of payments to or by the audited Party under this Agreement.  In the event that the final result of the inspection reveals an undisputed underpayment or overpayment, the underpaid or overpaid amount shall be settled within [*] after the Auditor’s report.  The auditing Party shall bear the full cost of such audit unless such audit reveals an overpayment to, or an underpayment by, the audited Party that resulted from a discrepancy in the financial report provided by the audited Party for the audited period, which underpayment or overpayment was more than [*] of the amount set forth in such report, in which case the audited Party shall reimburse the auditing Party for the costs for such audit.  With respect more specifically to [*], in addition to the right of inspection and audit by an Auditor, [*] upon reasonable notice sent by the paying Party to the requesting Party and during regular business hours.    

9.5 Late Payments.  In the event that any payment due under this Agreement is not paid when due in accordance with the applicable provisions of this Agreement, the payment shall accrue interest from the date due [*]; provided, however, that in no event shall such rate exceed the maximum legal annual interest rate.  The payment of such interest shall not limit the Party entitled to receive payment from exercising any other rights it may have as a consequence of the lateness of any payment. 

10.

Intellectual Property 

10.1 Ownership. 

(a) Data.  All Data generated in connection with any Development or Commercial activities with respect to any Product conducted solely by or on behalf of Rigel and its Affiliates and licensees (other than Kissei) (the “Rigel Data”) shall be the sole and exclusive property of Rigel or its Affiliates or licensees, as applicable.  All Data generated in connection with any Development or Commercial activities with respect to any Product conducted solely by or on behalf of Kissei or its Affiliates or Sublicensees (the “Kissei Data”) shall be the sole and exclusive property of Kissei or of its Affiliates or Sublicensees, as applicable.  All Data generated in connection with any Joint Development Work or joint Commercial activities with respect to any Product and for which the Parties are sharing Development Costs pursuant to Section ‎8.2(a) shall be jointly owned by the Parties.  For clarity, each Party shall have access and right to use and reference the other Party’s Data as and to the extent set forth in this Agreement. 

(b) Inventions.  Inventorship of any Inventions will be determined in accordance with the standards of inventorship and conception under U.S. patent laws.  The Parties will work together to resolve any issues regarding inventorship or ownership of Inventions.  Ownership of Inventions will be allocated as follows:

(i) Each Party shall solely own any Inventions made solely by its and its Affiliates’ employees, agents, or independent contractors, and the Parties shall jointly own any Inventions that are made jointly by employees, agents, or independent contractors of one Party and its Affiliates together with employees, agents, or independent contractors of the other Party and its Affiliates (“Joint Inventions”).  All Patents claiming patentable Joint Inventions shall be referred to herein as “Joint Patents”.  Except to the extent either Party is restricted by the licenses granted to the other Party under this Agreement, each Party shall be entitled to practice, license, assign, and otherwise exploit its interest under the Joint Inventions and Joint Patents without the duty of accounting or seeking consent from the other Party.

(ii) All data, Inventions, and Patents claiming such Inventions that relate to the composition, manufacture, or use of any Compound, or any improvement of any such composition, manufacture, or

use, including in combination with other agents or components, together with all intellectual property rights therein, shall be deemed “Compound Inventions”.  To the extent that any Compound Invention is made by Kissei, whether solely or jointly with Rigel, such Compound Invention shall be included in the license granted to Rigel by Kissei under Section 2.4, without additional consideration.  Effective only upon the later of the expiration of the Commercialization Term or the expiration or termination of this Agreement: (A) Kissei hereby assigns to Rigel its rights, title, and interest in and to all Compound Inventions, and (B) solely in the event that the Commercialization Term expires, Rigel hereby grants to Kissei a fully-paid, royalty-free, perpetual, irrevocable, exclusive license under such Compound Inventions assigned by Kissei to Rigel for Kissei to use, sell, offer for sale, import, and otherwise Commercialize the Products in the Field in the Kissei Territory.    

10.2 Patent Prosecution and Maintenance.    

(a) Rigel Patents. 

(i) Subject to this Section ‎10.2(a), Rigel shall have the sole right and obligation (subject to Section 10.2(a)(ii)) to control the preparation, filing, prosecution, and maintenance (including any interferences, reissue proceedings, reexaminations, inter partes review, patent term extensions, applications for supplementary protection certificates, oppositions, invalidation proceedings and defense of validity or enforceability challenges) of the Rigel Patents (including Joint Patents) worldwide, [*] using counsel of its own choice.   Rigel shall keep Kissei informed of material progress with regard to the preparation, filing, prosecution, and maintenance of the Rigel Patents in the Kissei Territory, sufficiently in advance for Kissei to be able to review any material documents, including content, timing, and jurisdiction of the filing of such Rigel Patents in the Kissei Territory, and Rigel shall consult with, and consider in good faith the requests and suggestions of, Kissei with respect to strategies for filing, prosecuting, and defending, if any, the Rigel Patents in the Kissei Territory.

(ii) In the event that Rigel desires to abandon or cease prosecution or maintenance of any Rigel Patent (including Joint Patent) in any country in the Kissei Territory, Rigel shall provide reasonable prior written notice to Kissei of such intention to abandon (which notice shall, to the extent possible, be given no later than [*] prior to the next deadline for any action that must be taken with respect to any such Rigel Patent in the relevant patent office).  In such case, upon Kissei’s written election provided no later than [*] after such notice from Rigel, Kissei shall have the right to assume prosecution and maintenance of such Rigel Patent at Kissei’s expense, and any claim included in such Rigel Patent shall cease to be a Valid Claim under this Agreement.  If Kissei does not provide such election within [*] after such notice from Rigel, Rigel may, in its sole discretion, continue prosecution and maintenance of such Rigel Patent or discontinue prosecution and maintenance of such Rigel Patent.

(iii) Rigel shall update Exhibit B on [*] basis during the Commercialization Term.  Notwithstanding the foregoing, solely with respect to [*] during the Term, Kissei shall have the right to [*] the update [*].  If Rigel [*] but shall also [*] under this Agreement, provided that, for clarity, in the event [*] under this Agreement. If Rigel disagrees with Kissei [*], such disagreement shall be subject to the dispute resolution process set forth in Article 15 (the  “Disputed Claims”).

(b) Kissei Patents.    

(i) Subject to this Section ‎10.2(b), Kissei shall have the first right, but not the obligation, to control the preparation, filing, prosecution and maintenance (including any interferences, reissue proceedings, reexaminations, patent term extensions, applications for supplementary protection certificates, oppositions, invalidation proceedings, and defense of validity or enforceability challenges) of all Kissei Patents (other than Joint Patents) worldwide, [*] by counsel of its own choice in the Kissei Territory and by counsel mutually agreed to by the Parties in the Rigel Territory.  Kissei shall keep Rigel informed of the status of filing, prosecution, maintenance, and defense, if any, of the Kissei Patents, and, [*] for Patents claiming or covering a Compound Invention, Kissei shall consult with, and consider in full good faith the requests and suggestions of, Rigel with respect to strategies for filing, prosecuting, and defending such Kissei Patents.

(ii) In the event that Kissei desires to abandon or cease prosecution or maintenance of any Kissei Patent, Kissei shall provide reasonable prior written notice to Rigel of such intention to abandon (which notice shall, to the extent possible, be given no later than [*] prior to the next deadline for any action that must be taken with respect to any such Kissei Patent in the relevant patent office).  In such case, upon Rigel’s written election provided no later than [*] after such notice from Kissei, Rigel shall have the right to assume prosecution and maintenance of such Kissei Patent at Rigel’s expense and Kissei shall assign to Rigel all of its rights, title, and interest in and to such Kissei Patent.  If Rigel does not provide such election within [*] after such notice from Kissei, Kissei may, in its sole discretion, continue prosecution and maintenance of such Kissei Patent or discontinue prosecution and maintenance of such Kissei Patent.

(c) Cooperation.  Each Party agrees to cooperate fully in the preparation, filing, prosecution, maintenance, and defense, if any, of Patents under Section ‎10.2 and in the obtaining and maintenance of any patent term extensions and supplementary protection certificates and their equivalents, [*].  Such cooperation includes (i) executing all papers and instruments, or requiring its employees or contractors, to execute such papers and instruments, so as enable the other Party to apply for and to prosecute patent applications in any country as permitted by Section ‎10.2; and (ii) promptly informing the other Party of any matters coming to such Party’s attention that may affect the preparation, filing, prosecution, or maintenance of any such patent application and the obtaining of any patent term extensions or supplementary protection certificates or their equivalents.

10.3 Patent Enforcement. 

(a) Notice.  Each Party shall notify the other within [*] of becoming aware of any alleged or threatened infringement by a Third Party of any of the Rigel Patents (including Joint Patents) in the Kissei Territory, which infringement adversely affects or is reasonably expected to adversely affect any Product, including any declaratory judgment, opposition, or similar action alleging the invalidity, unenforceability, or non-infringement of any of the Rigel Patents (collectively, “Product Infringement”).    

(b) Enforcement Right.  Rigel shall have the first right to bring and control any legal action in connection with such Product Infringement at its own expense as it reasonably determines appropriate.  If Rigel (i) decides not to bring such legal action against a Product Infringement (the decision of which Rigel shall inform Kissei promptly) or (ii) Rigel otherwise fails to bring such legal action against a Product Infringement within [*] of first becoming aware of such Product Infringement, Kissei shall have the right to bring and control any legal action in connection with such Product Infringement at its own responsibility and expense and in consultation with Rigel.

(c) Collaboration.  Each Party shall provide to the enforcing Party reasonable assistance in such enforcement, at such enforcing Party’s request and expense, including to be named in such action if required by Applicable Laws to pursue such action.  The enforcing Party shall keep the other Party regularly informed of the status and progress of such enforcement efforts, shall reasonably consider the other Party’s comments on any such efforts, including determination of litigation strategy and filing of material papers to the competent court.  The non-enforcing Party shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense, but such Party shall at all times cooperate fully with the enforcing Party. 

(d) Expense and Recovery. 

(i) Except as set forth in subsection (ii) below, the enforcing Party shall be solely responsible for any cost and expenses incurred by such Party as a result of such enforcement action.  If such Party recovers monetary damages in such enforcement action, such recovery shall be allocated [*].

(ii) Notwithstanding the foregoing, if [*] is the enforcing Party against a Product Infringement in the Kissei Territory, [*] shall have the option to share [*] the cost and expense incurred by [*] in such enforcement action, which option [*] may exercise by providing written notice to [*] within [*] after receiving a notice from [*] that it has determined to bring such action.  If [*] exercises such option, then (1) [*] shall reimburse [*] for

[*] of all costs and expenses incurred by [*] in such enforcement action, within [*] from the date of invoice for such costs and expenses provided by [*]; and (2) if [*] recovers any monetary damages in such enforcement action, such recovery shall be allocated [*].

(e) Other Infringement.  Except for Product Infringement as set forth above, each Party shall have the exclusive right to enforce its own Patent against any infringement anywhere in the world.  For clarity, Rigel shall have the exclusive right to enforce (i) the Rigel Patents against any infringement in the Kissei Territory that is not a Product Infringement, and (ii) the Rigel Patents and Joint Patents against any infringement in the Rigel Territory, in each case at its own expense as it reasonably determines appropriate.  The Parties shall discuss global enforcement strategy for the Rigel Patents and Kissei Patents, including the defense of validity and enforceability challenges arising from any enforcement action.   

(f) Infringement of Third Party Rights.  If any Product used or sold by Kissei, its Affiliates, or Sublicensees becomes the subject of a Third Party’s claim or assertion of infringement of any intellectual property rights in a jurisdiction within the Kissei Territory, Kissei shall promptly notify Rigel and the Parties shall promptly meet to consider the claim or assertion and the appropriate course of action and may, if appropriate, agree on and enter into a “common interest agreement” wherein the Parties agree to their shared, mutual interest in the outcome of such potential dispute.  Absent any agreement to the contrary, and subject to claims for indemnification under Article ‎12, each Party may defend itself from any such Third Party claim at its own cost and expense, provided, however, that the provisions of Section 10.3 shall govern the right of Kissei to assert a counterclaim of infringement of any Rigel Patents.

10.4 Patents Licensed From Third Parties.  Each Party’s rights under this Article ‎10 with respect to the prosecution and enforcement of any Rigel Patent and Kissei Patent shall be subject to the rights (a) retained by any upstream licensor to prosecute and enforce such Patent Right, if such Patent Right is subject to an upstream license agreement; and (b) granted to any Third Party prior to such Patent Right becoming subject to the license grant under this Agreement.

10.5 Trademarks. 

(a) Product Trademarks.  Subject to 10.5(c), each Party shall develop and adopt trademarks, including trade names, trade dresses, branding, and logos, to be used for the Products (the “Product Marks”) in its own territory [*]; provided, however, that the Parties shall collaborate to have a global, worldwide trademark to be used on the Product where possible and in such cases Rigel shall own such global Product ▇▇▇▇, subject to the license granted to Kissei in Section ‎10.5(b).  For clarity, Kissei may develop a trademark for its Commercialization of the Product in the Kissei Territory, which trademark is the notation of each national language in each country of the Kissei Territory parallel to Rigel’s global, worldwide trademark in the Kissei Territory (the “Kissei Product ▇▇▇▇”), and Kissei shall own such Kissei Product ▇▇▇▇. Each Party shall own all Product Marks developed by such Party.  Each Party shall be responsible for the registration, maintenance, defense, and enforcement of the Product Marks [*] using counsel of its own choice in its respective territory.  Kissei shall keep Rigel informed of material progress with regard to the registration, prosecution, maintenance, and defense, if any, of any Product Marks in the Kissei Territory, including content, timing, and jurisdiction of the filing of such Product Marks in the Kissei Territory. 

(b) Trademark License.  Kissei shall use the Product Marks to Commercialize the Product in the Kissei Territory.  In addition, unless prohibited by Applicable Laws, Kissei shall use Commercially Reasonable Effort to include Rigel’s corporate trademark on the packaging and product information of the Products sold in the Kissei Territory to indicate that the Product is licensed from Rigel.  Rigel hereby grants to Kissei a limited, royalty-free license to use Rigel’s corporate trademark and Product Marks solely in connection with the Commercialization of the Product in the Kissei Territory under this Agreement.  All use of the Product Marks and Rigel’s corporate trademark shall comply with Applicable Laws and shall be subject to Rigel’s prior review and written approval, provided that such Rigel’s approval shall not be unreasonably withheld and delayed.  For clarity, Kissei shall also include its (or its Affiliate’s or Sublicensee’s, as applicable) corporate logo in the Product sold in the Kissei Territory.

(c) Global Strategy.  Where Rigel reasonably believes in good faith that a Product ▇▇▇▇ developed by Kissei is not appropriate and conflicts with Rigel’s global strategy for the Product, the Parties shall use reasonable commercial efforts to agree on an alternative Product ▇▇▇▇.

Indemnification

12.1 Indemnification by Rigel.  Rigel hereby agrees to defend, indemnify, and hold harmless Kissei and its Affiliates and their respective directors, officers, employees, and agents (each, a “Kissei Indemnitee”) from and against any and all liabilities, expenses, and losses including any product liability, personal injury, property damage, including reasonable legal expenses and attorneys’ fees (collectively, “Losses”), to which any Kissei Indemnitee may become subject as a result of any claim, demand, action, or other proceeding by any Third Party to the extent such Losses arise out of or result from: (a) the Development, use, manufacture, handling, storage, Commercialization, or other disposition of any Compound or Product by Rigel or its Affiliates or licensees or the contractors of any of them

(excluding any activities by or on behalf of Kissei or its Affiliates or Sublicensees), (b) the negligence or willful misconduct of any Rigel Indemnitee, or (c) the breach by Rigel of any warranty, representation, covenant, or agreement made by Rigel in this Agreement; except, in each case (a)-(c), to the extent such Losses arise out of any activities set forth in Section ‎12.2(a), (b), or (c) for which Kissei is obligated to indemnify any Rigel Indemnitee(s) under Section ‎12.2.

12.2 Indemnification by Kissei.  Kissei hereby agrees to defend, indemnify, and hold harmless Rigel, its Affiliates, and licensees and their respective directors, officers, employees, and agents (each, a “Rigel Indemnitee”) from and against any and all Losses to which any Rigel Indemnitee may become subject as a result of any claim, demand, action, or other proceeding by any Third Party to the extent such Losses arise out of: (a) the Development, use, handling, storage, Commercialization, or other disposition of any Compound or Product by Kissei or its Affiliates or Sublicensees or the contractor of any of them, (b) the negligence or willful misconduct of any Kissei Indemnitee, or (c) the breach by Kissei of any warranty, representation, covenant, or agreement made by Kissei in this Agreement; except, in each case (a)-(c), to the extent such Losses arise out of any activities set forth in Section ‎12.1(a), (b), or (c) for which Rigel is obligated to indemnify any Kissei Indemnitee(s) under Section ‎12.1.

12.3 Procedure.  A party that intends to claim indemnification under this Article ‎12 (the “Indemnitee”) shall promptly notify the indemnifying Party (the “Indemnitor”) in writing of any Third Party claim, demand, action, or other proceeding (each, a “Claim”) in respect of which the Indemnitee intends to claim such indemnification, and the Indemnitor shall have sole control of the defense or settlement thereof.  The Indemnitee may participate at its expense in the Indemnitor’s defense of and settlement negotiations for any Claim with counsel of the Indemnitee’s own choice.  The indemnity arrangement in this Article ‎12 shall not apply to amounts paid in settlement of any action with respect to a Claim if such settlement is effected without the consent of the Indemnitor, which consent shall not be unreasonably withheld or delayed.  The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any action with respect to a Third Party Claim shall only relieve the Indemnitor of its indemnification obligations under this Article ‎12 if and to the extent the Indemnitor is actually prejudiced thereby.  The Indemnitee shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action with respect to a Claim covered by this indemnification.

(b) If the Reviewing Party notifies the Disclosing Party within the applicable time period set forth in subsection (a) above that such publication or presentation, in either Party reasonable judgment: 

(i) contains an invention for which the Reviewing Party desires to obtain patent protection, the Disclosing Party shall delay such publication or presentation for a period of up to [*] (or such other time period agreed by the Parties in writing) to permit the preparation and filing of a patent application for such invention, or

(ii) contains any Confidential Information of the Reviewing Party, or could be expected to have an adverse effect on the commercial value of any Confidential Information disclosed by the Reviewing Party  to the Disclosing Party, the Parties shall attempt to agree on revisions to the applicable disclosure so as to preserve both the commercial value of such Confidential Information and the scientific merit of such disclosure, provided that if and to the extent the Parties are unable to agree, the Disclosing Party shall delete such Confidential Information from the proposed publication or presentation.

(d) Cost of Ongoing Trials.  If there is any ongoing Clinical Trial of the Product under the Development Plan for which the Parties are sharing costs, then Kissei shall continue to share the cost of such Clinical Trial until [*].  The remaining costs from [*] until completion of such Clinical Trial (or early termination of such Clinical Trial by Rigel) shall be borne entirely by Rigel following [*].  

(e) Commercial Wind-Down.  The Parties agree that Kissei shall (i) continue certain ongoing Commercial activities of Kissei and its Affiliates and Sublicensees with respect to any Product in the Kissei Territory for a period of up to [*] after the effective date of termination and (ii) handoff such Commercial activities to Rigel or its designee, on a timetable to be set by the Parties, not to exceed [*] after the effective date of termination, and in compliance with all Applicable Laws.  During such commercial wind-down period, Kissei shall continue to book sales and pay the Transfer Price to Rigel in accordance with Section ‎8.5.  Except as necessary to conduct the foregoing activities as directed by Rigel, Kissei shall immediately discontinue its (and shall ensure that its Affiliates and Sublicensees immediately discontinue their) promotion, marketing, offering for sale, and servicing of the Product and its use of all Product Marks.  In addition, Kissei shall immediately deliver to Rigel ([*]) all samples, demonstration equipment, sales materials, catalogs, and literature of Rigel in Kissei’s possession or control.  

(f) Transition Assistance.  Kissei shall use Commercially Reasonable Efforts to seek an orderly transition of the Development and Commercialization of the Compound and Products to Rigel or its designee.  Except in the event of termination by Kissei under Section 14.2(a), Kissei shall, [*], provide reasonable consultation and assistance for a period of no more than [*] after the effective date of termination for the purpose of transferring or transitioning to Rigel all Kissei Know-How not already in Rigel’s possession and, at Rigel’s request, all then-existing commercial arrangements relating to the Products that Kissei is able, using Commercially Reasonable Efforts, to transfer or transition to Rigel or its designee, in each case, to the extent reasonably necessary for Rigel to continue the Development or Commercialization of the Compound and Products in the Kissei Territory.  If any such contract between Kissei and a Third Party is not assignable to Rigel or its designee (whether by such contract’s terms or because such contract does not relate specifically to the Products) but is otherwise reasonably necessary for Rigel to continue the Development or Commercialization of the Compound and Products in the Kissei Territory, or if Kissei is performing such work for the Compound and Product itself (and thus there is no contract to assign), then Kissei shall reasonably cooperate with Rigel to negotiate for the continuation of such services for Rigel from such entity, or Kissei shall use Commercially Reasonable Efforts to continue to perform such work for Rigel, as applicable, for a reasonable period (not to exceed [*]) after the effective date of termination at Rigel’s cost until Rigel establishes an alternate, validated source of such services. 

(g) Remaining Inventories.  Other than termination for safety reasons pursuant to Section ‎14.2(d), Kissei shall have the right to sell out the inventory of the Products held by Kissei as of the notice date of termination until the effective date of termination, subject to Kissei’s payment obligations to Rigel under Article ‎8 with respect to such sales.

(h) Trademarks.  The license granted to Kissei under Section 10.5(b) shall terminate and Kissei shall cease immediately the use of all Rigel Trademarks.  Unless this Agreement is terminated pursuant to Section ‎14.3(c), Kissei shall transfer and assign to Rigel, [*], all Kissei Product Marks.

(i) Non-Compete.  Following any termination of this Agreement by Rigel pursuant to Section ‎14.2, neither Kissei nor any of its Affiliates shall (directly or indirectly, either with or without a bona fide collaborator or any other Third Party) commercialize any Competing Product for a period of [*] following the effective date of such termination.

14.5 Confidential Information.  Upon expiration or termination of this Agreement in its entirety, except to the extent that a Party obtains or retains the right to use the other Party’s Confidential Information, each Party shall promptly return to the other Party, or delete or destroy, all relevant records and materials in such Party’s possession or control containing Confidential Information of the other Party; provided that such Party may keep one copy of such materials for archival purposes only subject to continuing confidentiality obligations.  All Kissei Data and Regulatory Filings assigned to Rigel upon termination of this Agreement will be deemed Rigel’s Confidential Information and no longer Kissei’s Confidential Information.

14.6 Survival.  Expiration or termination of this Agreement shall not relieve the Parties of any obligation or right accruing prior to such expiration or termination.  Except as set forth below or elsewhere in this Agreement, the obligations and rights of the Parties under the following provisions of this Agreement shall survive expiration or

termination of this Agreement: Articles 1, 9 (with respect to payment obligations accrued prior to such expiration or termination and/or during the Extended Commercialization Term), 12, 13, 15 and 16, and Sections 2.6, 4.15 (the 3rd, 4th and 5th sentences only), 8.5(b) and 8.5(e) (each solely during the Extended Commercialization Term), 10.1, 11.5, 14.4, 14.5 and 14.6.

14.7 Exercise of Right to Terminate.  All rights and obligations of a Party accrued prior to the effective date of a termination (including the rights to receive reimbursement for costs incurred prior to the effective date of such termination and payments accrued or due prior to the effective date of such termination) shall survive such termination.

14.8 Rights in Bankruptcy.  All rights and licenses granted under or pursuant to this Agreement by one Party to the other Party are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code or comparable provision of applicable bankruptcy or insolvency laws, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code or comparable provision of applicable bankruptcy or insolvency laws.  The Parties agree that a Party that is a licensee of such rights under this Agreement will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code or comparable provision of applicable bankruptcy or insolvency laws.  The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against a Party to this Agreement under the U.S. Bankruptcy Code or comparable provision of applicable bankruptcy or insolvency laws, the other Party will be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, and same, if not already in its possession, will be promptly delivered to it (a) upon any such commencement of a bankruptcy or insolvency proceeding upon its written request therefor, unless the bankrupt Party elects to continue to perform all of its obligations under this Agreement, or (b) if not delivered under (a) above, following the rejection of this Agreement by or on behalf of the bankrupt Party upon written request therefor by the other Party.

Dispute Resolution 

15.1 Objective.  The Parties recognize that disputes as to matters arising under or relating to this Agreement or either Party’s rights and obligations hereunder may arise from time to time.  It is the objective of the Parties to establish procedures to facilitate the resolution of such disputes in an expedient manner by mutual cooperation and without resort to litigation.  To accomplish this objective, the Parties agree to follow the procedures set forth in this Article ‎15 to resolve any such dispute if and when it arises.

15.2 Executive Mediation.  The Parties shall attempt to settle any dispute, controversy, or claim that arises out of, or relates to, any provision of the Agreement (“Disputed Matter”) by first referring the Disputed Matter to the Executive Officers (or their respective designees having the authority to settle such Disputed Matter).  Either Party may initiate such informal dispute resolution by sending written notice of the Disputed Matter to the other Party, and, within [*] after such notice, the Executive Officers (or their respective designees) shall meet for attempted resolution by good faith negotiations.  If the Executive Officers (or their respective designees) are unable to resolve such dispute within [*] of their first meeting for such negotiations, either Party may seek to have such dispute resolved in accordance with Section ‎15.3 below. 

15.3 Dispute Resolution.    

(a) If the Parties are unable to resolve a Disputed Matter using the process described in Section ‎15.2, then a Party seeking further resolution of the Disputed Matter will submit the Disputed Matter to resolution by final and binding arbitration.  Whenever a Party decides to institute arbitration proceedings, it will give written notice to that effect to the other Party.  Arbitration will be held in [*] and administered by the International Chamber of Commerce pursuant to its ICC International Arbitration Rules then in effect (the “Rules”), except as otherwise provided herein and applying the substantive law specified in Section ‎16.1.  The arbitration will be conducted by a panel of three (3) arbitrators appointed in accordance with the Rules; provided that each Party will, within [*] after the institution of the arbitration proceedings, appoint an arbitrator, and such arbitrators will together, within [*], select a third (3rd) arbitrator as the chairperson of the arbitration panel.  Each arbitrator must have significant business or

legal experience in the pharmaceutical business.  If the two (2) initial arbitrators are unable to select a third (3rd) arbitrator within such [*] period, the third (3rd) arbitrator will be appointed in accordance with Rules.  After conducting any hearing and taking any evidence deemed appropriate for consideration, the arbitrators will be requested to render their opinion within [*] of the final arbitration hearing.  No panel of arbitrators will have the power to award damages excluded pursuant to Section ‎12.5 under this Agreement and any arbitral award that purports to award such damages is expressly prohibited and void ab initio.  Decisions of the panel of arbitrators that conform to the terms of this Section ‎15.3 will be final and binding on the Parties and judgment on the award so rendered may be entered in any court of competent jurisdiction.  The losing Party, as determined by the panel of arbitrators, will pay all of the ICC administrative costs and fees of the arbitration and the fees and costs of the arbitrators, and the arbitrators will be directed to provide for payment or reimbursement of such fees and costs by the losing Party.  If the panel of arbitrators determines that there is no losing Party, the Parties will each bear one-half of those costs and fees and the arbitrators’ award will so provide.  Notwithstanding the foregoing, each Party shall bear its own attorneys’ fees, expert or witness fees, and any other fees and costs, and no such fees or costs will be shifted to the other Party.

(b) Notwithstanding the terms of and procedures set forth in Section ‎15.2 or ‎15.3(a), any applications, motions, or orders to show cause seeking temporary restraining orders, preliminary injunctions, or other similar preliminary or temporary legal or equitable relief (“Injunctive Relief”) concerning a Disputed Matter (including Disputed Matters arising out of a potential or actual breach of the confidentiality and non-use provisions in Article ‎13) may immediately be brought in the first instance and without invocation or exhaustion of the procedures set forth in subsections (a) and (b) for hearing and resolution in and by any court of competent jurisdiction.  Alternatively, a party seeking Injunctive Relief may immediately institute arbitral proceedings without invocation or exhaustion of the procedures set forth in subsections (a) and (b), and any such Injunctive Relief proceedings will be administered by the ICC pursuant to its ICC emergency arbitration procedures then in effect and applying the substantive law specified in Section ‎16.1.  In either event, once the Injunctive Relief proceedings have been conducted and a decision is rendered thereon by the court or arbitral forum, the Parties shall, if the Disputed Matter is not finally resolved by the Injunctive Relief, proceed to resolve the Disputed Matter in accordance with the terms of Section ‎15.2 and ‎15.3(a).  

(c) Notwithstanding the foregoing, this Section ‎15.3 shall not apply to any dispute, controversy, or claim that concerns (i) the validity, enforceability, or infringement of a patent, trademark, or copyright; or (ii) any antitrust, anti-monopoly, or competition law or regulation, whether or not statutory.  Disputes regarding the foregoing shall be brought in a court of competent jurisdiction in which such patent or trademark or copyright was granted or arose, or in which such law or regulation applies, in each case as applicable.
