3. COLLABORATION

3.1 Program Target Profiles.

(a) PTP1 and PTP2. As of the Effective Date, the Parties have selected PTP1 and PTP2 as the Program Target Profiles for the first two R&D Programs to be conducted under this Agreement.

(b) Program Target Profile Proposal and Selection.

(i) By a Party Via the SOC. From time to time during the Exclusivity Period or, at a Party’s discretion during any Extended Exclusivity Period, either

21.

Party may propose to the SOC specific protein or gene target(s) within the Collaboration Scope, or, if mutually agreed by the Parties, outside the Collaboration Scope (in either case, a “Proposed PTP”), for potential selection as a Program Target Profile for the conduct of:

(1) an R&D Program, in the case of PTP3 and PTP4; or

(2) an Additional R&D Program, in the case of any Program Target Profile other than an Initial PTP (an “Additional PTP”).

The SOC shall promptly consider each Proposed PTP and determine whether or not to recommend the selection thereof as a Program Target Profile for the conduct of an R&D Program or Additional R&D Program, as applicable.

(ii) By Aurigene. In addition, if, during the Exclusivity Period, Aurigene conducts any drug discovery and research program directed to a potential Program Target Profile for Immuno-oncology (an “Aurigene Immuno-oncology PTP”), Aurigene shall provide regular updates to Curis regarding the progress and results of such Aurigene Immuno-oncology PTP program, and, if and at such time as Aurigene has generated an Aurigene Immuno-oncology Data Package for such potential Aurigene Immuno-oncology PTP, Aurigene shall promptly deliver such Aurigene Immuno-oncology PTP Data Package to Curis. During the applicable Data Package Review Period, Aurigene shall make qualified Aurigene representatives reasonably available to Curis (at a SOC meeting or otherwise) for discussion of such Aurigene Immuno-oncology PTP Data Package. Curis shall have until the expiration of the applicable Data Package Review Period to elect whether to add such Aurigene Immuno-oncology PTP as a Program Target Profile for the conduct of an R&D Program or Additional R&D Program, as applicable. If Curis informs Aurigene that it declines to select such Aurigene Immuno-oncology PTP as a Program Target Profile for a Program, or if Curis fails to inform Aurigene of Curis’ decision regarding such Aurigene Immuno-oncology PTP prior to expiration of such Data Package Review Period, Aurigene’s exclusivity obligations with respect solely to such Aurigene Immuno-oncology PTP shall cease.

(c) Timing of Selection of PTP3 and PTP4. The Parties, via the SOC, shall use Commercially Reasonable Efforts to recommend the selection of PTP3 and PTP4 in accordance with Section 3.1(b)(i) prior to the end of the Initial Exclusivity Period. Alternatively, if, during the Initial Exclusivity Period and prior to recommendation of the selection of both PTP3 and PTP4, Aurigene generates an Aurigene Immuno-oncology PTP Data Package with respect to an Aurigene Immuno-oncology PTP, Curis may select such Aurigene Immuno-oncology PTP as PTP3 or PTP4, as applicable. Curis acknowledges that SOC recommendation or Curis’ selection, as applicable, of any Proposed PTP or Aurigene Immuno-oncology PTP as PTP3 or PTP4 shall be subject to the R&D Program selection payment obligation set forth in Section 6.3.

(d) Additional R&D Programs. Curis acknowledges that SOC recommendation or Curis’ selection, as applicable, of any Proposed PTP or Aurigene Immuno-oncology PTP as an Additional PTP for the conduct of an Additional R&D Program shall be subject to the Additional R&D Plan Payment obligations set forth in Section 6.4.

22.

3.2 R&D Plans. At the first SOC meeting, in the case of PTP1 and PTP2, and as promptly as practicable (and in any event within [**] days) after (1) SOC recommendation of the selection of, or Curis’ selection of (as applicable), PTP3 and PTP4 or any Additional PTP, or (2) Curis’ election to initiate a new Program for Follow-On Molecules for a particular Program Target Profile pursuant to Section 3.8, the SOC shall review and recommend, subject to each Party’s final approval of the aspects that are within such Party’s final decision-making authority pursuant to Sections 2.6(a) and 2.6(b), a written plan for the applicable Program to be conducted with respect to such Program Target Profile (each, an “R&D Plan”), which shall be subject to amendment by the SOC from time to time in accordance with Article 2. Each R&D Plan shall:

(a) identify the applicable Program Target Profile;

(b) set forth:

(i) the specific discovery, research and preclinical activities to be undertaken as part of the Program for such Program Target Profile;

(ii) criteria for Lead Candidate selection; and

As used herein, the term “R&D Plan” shall mean the R&D Plan as then in effect, including all updates and amendments thereto made in accordance with the terms of this Agreement.

3.3 Aurigene Diligence. On a Program-by-Program basis, Aurigene shall use Commercially Reasonable Efforts to conduct each Program in an expeditious manner, to generate at least one Lead Candidate from each Program, and to present to the SOC at least one Development Candidate from each Program and deliver to Curis the corresponding Development Candidate Data Package; provided, however, that:

(a) the foregoing diligence obligations with respect to the R&D Program for each of PTP3 and PTP4 are subject to Curis’ payment when due of the Lead Candidate selection milestone payment for such R&D Program in accordance with Section 6.3;

(b) the foregoing diligence obligations with respect to each Additional R&D Program are subject to Curis’ payment when due of the Additional R&D Plan Payments for such Additional R&D Program in accordance with Section 6.4;

(c) in the event that, despite conducting the activities for which it is responsible under a particular R&D Plan and using its Commercially Reasonable Efforts to generate a Lead Candidate for the applicable Program Target Profile, Aurigene is unable to generate a Lead Candidate for such Program Target Profile, Aurigene shall promptly call an SOC meeting, to be held within [**] days thereof, at which Aurigene shall present to the SOC all

23.

relevant data and information with respect to the Compounds generated in the performance of such R&D Plan, and the SOC shall discuss in good faith any technical feasibility issues encountered by Aurigene in its efforts to generate a Lead Candidate for such Program Target Profile, review the Lead Candidate criteria under such R&D Plan, and consider whether any amendment to such R&D Plan (whether to provide for Aurigene to perform additional activities, or to modify the Lead Candidate criteria set forth therein, or otherwise) is necessary or advisable. The Parties shall cooperate in good faith with any recommendation by the SOC to perform additional activities, including by one or more Third Parties selected by the SOC, in an effort to generate a Lead Candidate, with the costs borne as agreed to by the Parties. If, at such SOC meeting or within [**] days after the completion of any such additional activities determined by the SOC, a Lead Candidate has not been generated and the SOC does not select further activities to be undertaken in an effort to generate a Lead Candidate, then, at Curis’ option exercisable within [**] days after the SOC meeting at which the Compounds were presented or, if applicable, within [**] days after the SOC meeting at which the results of any such additional activities are presented, Curis may select any of the Compounds generated in the performance of such R&D Plan or any such additional activities as a Lead Candidate (without regard to whether or not it meets the Lead Candidate criteria set forth in the R&D Plan). If Curis does not select any such Compound as a Lead Candidate within the applicable period, then, unless otherwise agreed by the Parties in writing, the Program with respect to the applicable Program Target Profile shall terminate; and

(d) in the event that, despite conducting the activities for which it is responsible under a particular R&D Plan and using its Commercially Reasonable Efforts to generate a Development Candidate for the applicable Program, Aurigene shall promptly call an SOC meeting, to be held within [**] days thereof, at which Aurigene shall present to the SOC all relevant data and information with respect to the Program Compounds generated in the performance of such R&D Plan, and the SOC shall discuss in good faith any technical feasibility issues encountered by Aurigene in its efforts to generate a Development Candidate for such Program Target Profile, review the Target Molecule Profile under such R&D Plan, and consider whether any amendment to such R&D Plan (whether to provide for Aurigene to perform additional activities, or to modify the Target Molecular Profile set forth therein, or otherwise) is necessary or advisable. The Parties shall cooperate in good faith with any recommendation by the SOC to perform additional activities, including by one or more Third Parties selected by the SOC, in an effort to generate a Development Candidate, with the costs borne as agreed to by the Parties. If, at such SOC meeting or within [**] days after the completion of any such additional activities determined by the SOC, a Development Candidate has not been generated and the SOC does not select further activities to be undertaken in an effort to generate a Development Candidate, then Curis’ Option Period for the applicable Program shall begin on such date; provided, however, that if such Option Period expires unexercised and, within [**] months after expiration of such Option Period, (i) Aurigene generates a compound that, if it had been generated in the course of the applicable Program, would have been a Development Candidate, and (ii) Aurigene Controls such compound, Aurigene shall present such compound to Curis, and the Parties shall discuss in good faith the possibility of resuming the applicable Program.

3.4 Performance Standards. Aurigene shall perform each Program in close collaboration with Curis and in accordance with the applicable R&D Plan and the terms and conditions of this Agreement.

5. DEVELOPMENT, MANUFACTURING AND COMMERCIALIZATION

5.1 Development Plans.

(a) From and after Curis’ exercise of the Option with respect to a Program in accordance with Section 4.2, the Parties shall collaborate in the further development of the applicable Development Candidate, with Aurigene conducting IND-enabling preclinical (i.e., GLP toxicology) studies to support a US IND or equivalent filing and providing sufficient drug substance and drug product to support a Phase 1 Trial in the Curis Territory, subject to Section 5.5, and Curis having responsibility for preparing the IND or equivalent application and conducting further development activities, in each case, as more fully described in this Article 5. As promptly as reasonably practicable after such Option exercise, Curis shall prepare, in close consultation with Aurigene, and deliver to Aurigene a preliminary written preclinical development plan setting forth the IND-enabling studies, CMC Activities and other IND-enabling preclinical development activities that Curis then anticipates will be necessary for the filing of a US IND with respect to the applicable Development Candidate, [**]. Based on such [**], Curis shall [**] development plan [**] Aurigene [**] Curis then [**], including Curis’ [**] a “Development Plan”). For clarity, and notwithstanding any other provision of this Agreement to the contrary, Curis shall have [**] Development Plan.

(b) Each Development Plan shall be subject to amendment or update from time to time as follows:

(i) that portion of the Development Plan setting forth the activities for which [**] in accordance with Article 2; provided, however, that, as Curis [**];

(ii) prior to [**] and subject to [**], Curis may amend that portion of the Development Plan setting forth the activities for which [**]; and

(iii) after [**] and prior to [**]: (A) Curis may amend that portion of the Development Plan setting forth the activities for which [**], unless such amendment represents [**], in which case Curis shall [**]; and (B) Curis shall [**].

(c) At the reasonable request of [**] with respect to Development Plans, including [**], provided that this Section 5.1(c) is not intended to, and shall not, [**].

5.2 Performance Standards. Each Party shall perform the Development Plan activities for which it is responsible in accordance with the applicable Development Plan and the terms and conditions of this Agreement. In addition, each Party shall perform all such Development Plan activities in good scientific manner and in compliance with all Applicable Laws and, as applicable, GLP, GCP or GMP.

5.3 Performance of Development Plan Activities by Aurigene Affiliates and Subcontractors. Aurigene shall have the right to perform the Development Plan activities for

35.

which Aurigene is responsible through any Affiliate or Third Party subcontractor, subject to Curis’ prior written approval of any Third Party subcontractor, such approval not to be unreasonably withheld; provided, however, that (a) Xx. Xxxxx’x Laboratories Ltd and its subsidiaries are hereby deemed to be approved by Curis for purposes of this Section 5.3, and if the Affiliate or Third Party subcontractor that Aurigene proposes to use has (i) been debarred under Applicable Laws in the US, including 21 U.S.C. §335a, or any comparable Applicable Laws outside of the US, or received notice of any pending action or threat of action with respect to its debarment, or (ii) used in any capacity the services of any individual, corporation, partnership, institution or association which has been debarred under Applicable Laws in the US, including 21 U.S.C. §335a, or any comparable Applicable Laws outside of the US, then (1) Aurigene must seek prior written approval for an Affiliate or pre-approved Third Party subcontractor, and (2) it shall not be unreasonable for Curis to withhold approval of the Affiliate or Third Party subcontractor, including, in each case, Xx. Xxxxx’x Laboratories Ltd and its subsidiaries; and provided, further, that: (i) none of Curis’ rights hereunder are diminished or otherwise adversely affected as a result of such delegation or subcontracting; (ii) each such Affiliate and subcontractor undertakes in writing obligations of confidentiality and non-use regarding Confidential Information at least as stringent as those undertaken by the Parties pursuant to Article 8; (iii) prior to initiating performance of any Development Plan activities, each such Affiliate and Third Party subcontractor has signed a binding agreement or instrument assigning, and agreeing to assign, to Aurigene all data and other work product resulting from performance of such activities (subject to reasonable and customary exceptions for improvements to the applicable Affiliate’s or Third Party subcontractor’s pre-existing proprietary technology, or technology of broad applicability that such Affiliate or Third Party subcontractor uses for multiple products in addition to the applicable Program Compound or Product, provided, in each case, that such improvements do not use or incorporate Confidential Information of Curis), including all Patent Rights and other intellectual property rights therein; and (iv) Aurigene shall at all times be fully responsible for the performance of such Affiliate or subcontractor and for payment of such Affiliate or subcontractor.

5.4 Responsibility for Development and Commercialization in the Curis Territory.

(a) Curis Responsibility. From and after Curis’ exercise of the Option with respect to a Program, and except for Aurigene’s responsibility for performing IND-enabling preclinical development and any Aurigene CMC Activities under Section 5.4(b) and its Phase 1 supply obligations under Section 5.5, Curis shall be solely responsible for conducting the Development Plan for the applicable Development Candidate and otherwise for developing, registering and commercializing Program Compounds and Products in the Field in the Curis Territory. Without limiting the generality of the foregoing, Curis (itself or with or through its Affiliates or Sublicensees) shall be solely responsible for preparing and submitting all required Regulatory Filings in connection with obtaining and maintaining Regulatory Approvals, including all INDs and NDAs, with respect to Program Compounds and Products for each Licensed Program in the Field in the Curis Territory, at Curis’ sole expense. [**] Curis [**] Curis [**]. Curis shall [**] in compliance with all Applicable Laws and, [**]. Curis may [**], provided that: (i) [**] Aurigene’s [**] by the Parties [**], to Curis[**] of Aurigene[**]; and (iv) Curis shall [**].

36.

(b) Aurigene Responsibility. For each Licensed Program, unless otherwise agreed by the Parties, subject to Curis’ payment of any applicable Option exercise fees under Section 6.5, Aurigene shall be responsible for: (i) conducting (A) the IND-enabling studies of the applicable Development Candidate in accordance with Curis-approved protocols, (B) any Aurigene CMC Activities with respect to the applicable Development Candidate in accordance with the applicable Development Plan, and (C) any other IND-enabling preclinical development activities that the applicable Development Plan specifies will be the responsibility of Aurigene; in each case, in accordance with the applicable Development Plan; and (ii) providing sufficient drug substance and drug product to support a Phase 1 Trial in the Curis Territory, subject to Section 5.5. Subject to Curis’ payment when due of the milestone payment for Acceptance for Filing of the first IND for a Product from each Licensed Program in accordance with Section 6.6(a), 6.6(b) or 6.6(c), as applicable, Aurigene shall perform its Development Plan responsibilities and Phase 1 Trial supply obligations under Section 5.5, at Aurigene’s sole expense.

5.5 Development in the Aurigene Territory. For each Licensed Program that is not a Terminated Program, Aurigene may pursue Regulatory Approval in the Aurigene Territory only for the specific Product(s) from such Licensed Program for which Curis is pursuing or has obtained Regulatory Approval in the Curis Territory as set forth in the applicable Development Plan, and only for the same indication(s) and in the same dosage form(s) and formulation(s) as Curis is pursuing or has obtained Regulatory Approval in the Curis Territory, such that Aurigene will be able to use the data (including Curis Data) and results generated in the conduct of such Development Plan to support NDA filings and Regulatory Approvals with respect to such Product in the Aurigene Territory. However, if the applicable Regulatory Authority of a country in the Aurigene Territory requires, or Aurigene reasonably believes that the applicable Regulatory Authority of a country in the Aurigene Territory will require, the conduct of a particular IND-enabling study or clinical trial of a specific Product for which Curis is pursuing or has obtained Regulatory Approval in the Curis Territory, for the same indication(s) and in the same dosage form(s) and formulation(s) as Curis is pursuing or has obtained Regulatory Approval in the Curis Territory, which study or trial is not expressly contemplated by the applicable Development Plan as a condition to approving or maintaining approval of an NDA for such Product in such country, then Aurigene may conduct such IND-enabling study or clinical trial provided that Aurigene provides Curis written notice and a copy of the protocol for such study at least 30 days prior to the scheduled initiation of such study and considers in good faith any comments to the same received from Curis during such period.

5.6 Phase 1 Supply. For each Program with respect to which Curis exercises the Option in accordance with Section 4.2, Aurigene shall manufacture, or have manufactured, and supply to Curis sufficient quantities of drug substance and drug product, manufactured in accordance with GMP, for use in the conduct of a Phase 1 Trial of the applicable Development Candidate in the Curis Territory. Aurigene represents and warrants that all such Development Candidate drug substance or drug product (as applicable), will: (a) upon delivery to Curis, conform to the applicable specifications for such drug substance or drug product (as applicable) in effect at the time of delivery; (b) have been manufactured in compliance with GMP, as applicable to investigational drugs; and (c) be free and clear of any liens or encumbrances. Notwithstanding anything to the contrary in this Section 5.5, the Parties, through the SOC, may decide that drug substance or drug product may be purchased by Curis from a Third Party supplier at Curis’ expense.

37.

5.7 Clinical and Commercial Manufacture for the Curis Territory.

(a) Except for the Phase 1 Trial material that Aurigene is responsible for supplying pursuant to Section 5.5, Curis shall be solely responsible for the manufacture and supply of clinical and commercial Product for use or distribution in the Curis Territory. With respect to each Program Compound or Product, but subject to Sections 5.7(b) and (c), Aurigene shall have an option to nominate one primary global supplier of such drug substance or drug product (the “Supply Option”); provided, however, that the Supply Option shall be subject to the applicable Aurigene-nominated supplier:

(i) being competitive in pricing, quality, and production capacity/capability as other potential contract manufacturing organization (“CMO”) providers of drug substance or drug product;

(ii) then operating a GMP-compliant manufacturing facility at which such drug substance or drug product would be manufactured;

(iii) having all government permits, including health, safety and environmental permits, necessary for the operation of such facility;

(iv) not having received any Form FD-483 notice (or foreign equivalent) or any FDA or other Regulatory Authority refusal to file, rejection or warning letter that has not been fully addressed by such supplier to the satisfaction of the applicable Regulatory Authority; and

(v) not (A) being debarred under Applicable Laws in the US, including 21 U.S.C. §335a, or any comparable Applicable Laws outside of the US, or received notice of any pending action or threat of action with respect to its debarment, or (B) using in any capacity the services of any individual, corporation, partnership, institution or association which has been debarred under Applicable Laws in the US, including 21 U.S.C. §335a, or any comparable Applicable Laws outside of the US;

and provided, further, that Curis (or a Sublicensee or Third Party Acquirer, as applicable) will have the right to establish a second source of drug substance or drug product for the Curis Territory not to exceed 50% of total requirements while the Aurigene nominated supplier is materially fulfilling its obligations to Curis.

(b) In the event that Curis enters into a sublicense agreement with a Third Party with respect to any Product, Curis will exercise commercially reasonable efforts to include the Supply Option (subject to all of the conditions set forth in Section 5.7(a)) in such sublicense agreement, but the Parties acknowledge that Curis does not have the power, and agree that Curis is not required, to compel such Sublicensee to include the Supply Option in such sublicense agreement; provided, however, that in such event, the applicable royalty rates in clause (y) of Section 6.8(a) shall increase by [**]% with respect to such Sublicensee. In the event this increase in royalty rates under clause (y) of Section 6.8(a), results in an unreasonable economic

38.

imbalance between the Parties, the Parties shall meet and attempt in good faith to eliminate or otherwise modify this contemplated royalty increase so as to maintain a reasonable economic balance between the Parties.

(c) The Supply Option (subject to all of the conditions set forth in Section 5.7(a)) would survive a permitted assignment of this Agreement by Curis pursuant to Section 14.5. However, if the applicable Third Party Acquirer (directly or through its Affiliates) (i) has substantial GMP manufacturing capabilities of its own and wishes to manufacture Product internally, or (ii) has a bona fide existing arrangement, pre-dating its acquisition of Curis, with a CMO that has already been fully qualified to the Third Party Acquirer’s standards for the global supply of other products, then it shall not be a breach of this Agreement for such Third Party Acquirer, after considering in good faith an Aurigene-nominated global supplier of the applicable drug substance or drug product that satisfies all of the conditions set forth in Section 5.7(a), makes a business decision not to contract with such Aurigene-nominated supplier for supply of such drug substance or drug product; provided, however, that in such event, the applicable royalty rates in Section 6.7 and clause (y) of Section 6.8(a) shall increase by [**]%. In the event this increase in royalty rates under Section 6.7 and clause (y) of Section 6.8(a), results in an unreasonable economic imbalance between the Parties, the Parties shall meet and attempt in good faith to eliminate or otherwise modify this contemplated royalty increase so as to maintain a reasonable economic balance between the Parties. For clarity, if the Aurigene-nominated supplier does not satisfy all of the conditions of Section 5.7(a), then the Third Party Acquirer’s decision not to contract with such Aurigene-nominated supplier shall not result any increase to the royalty rates in Section 6.7 and clause (y) of Section 6.8(a).

5.8 Diligence.

(a) By Aurigene. On a Licensed Program-by-Licensed Program basis, Aurigene (directly or through permitted Affiliates or subcontractors) shall use Commercially Reasonable Efforts to perform its obligations under the Development Plan for such Licensed Program in an expeditious manner.

(b) By Curis. On a Licensed Program-by-Licensed Program basis, Curis (directly or through its Affiliates or Sublicensees) shall use Commercially Reasonable Efforts to develop, obtain Regulatory Approval for, and commercialize at least one Product for use within the Field in each of the Major Markets (including each of the Major EU Markets). For purposes of this Section 5.8(b), Commercially Reasonable Efforts shall be determined on a Major Market-by-Major Market basis, and it is anticipated that the level of effort will be different for different Major Markets, and may change over time, reflecting changes in the status of the Major Market involved.

5.9 Disclosure of Results.

(a) IND-Enabling Studies and Aurigene CMC Activities. Aurigene shall deliver to Curis the draft and final study reports for each IND-enabling study and disclose to Curis all results of Aurigene CMC Activities performed by or on behalf of Aurigene under a Development Plan, in each case, promptly following the availability thereof.

39.

(b) Other CMC Activities and Clinical Trials. Curis shall (i) disclose and provide a copy to Aurigene of all results of CMC Activities (other than Aurigene CMC Activities) performed by or on behalf of Curis, including CMC Activities in preparation for or connection with any NDA, and (ii) disclose and provide a copy to Aurigene of full tables, figures and listings from, and deliver a true and complete copy of the final study report for, each study, whether clinical or otherwise, of a Program Compound or Product conducted by or on behalf of Curis, in each case, promptly following the availability thereof. Curis shall disclose and provide a copy to Aurigene of all other information and data reasonably requested by Aurigene as necessary or useful for manufacture, development or commercialization of a Program Compound or Product in or for the Aurigene Territory.

5.10 Rights of Access and Reference to Regulatory Documents. On a Licensed Program-by-Licensed Program basis with respect to each Licensed Program, effective as of the filing of the first IND for a Product from such Licensed Program in a Major Market, Curis hereby grants to Aurigene the right to access and reference all INDs and NDAs submitted to, and Regulatory Approvals obtained from, any Regulatory Authority in a Major Market by Curis for Products from such Licensed Program (collectively, “Curis Regulatory Documents”); in each case, solely for the purposes of (a) obtaining and maintaining Regulatory Approvals for Products from such Licensed Program in the Field in the Aurigene Territory, and (b) complying with applicable pharmacovigilance and other regulatory requirements with respect to such Products in the Aurigene Territory. Curis shall, promptly upon Aurigene’s request, file with the applicable Regulatory Authority(ies) such letters of access or reference as may be necessary to accomplish the intent of this Section 5.10.

5.11 Safety Data Exchange. Each Party shall be solely responsible, at its own expense, for complying with all applicable regulatory requirements with respect to Products in such Party’s Territory, including all safety reporting to Regulatory Authorities in such Party’s Territory. The Parties shall, promptly upon reasonable request by either Party, negotiate in good faith and enter into a pharmacovigilance/safety data exchange agreement for Products (the “PV Agreement”), which shall set forth standard operating procedures governing the collection, investigation, reporting, and exchange of information concerning adverse drug reactions/experiences. The terms of the PV Agreement shall be no less stringent than those required by FDA and ICH guidelines and shall be sufficient to permit each Party to comply with its regulatory and legal requirements for the management and reporting of safety data regarding such Products by providing for the exchange of relevant information in appropriate format within applicable timeframes. Curis shall be responsible for maintaining, at its own expense, a global safety database for Products from each Licensed Program.

(c) Treatment of Milestone Payments for Additional Licensed Programs. Solely in the case of any Additional R&D Program that becomes a Licensed Program, if Curis receives a milestone payment from a Sublicensee with respect to the achievement by such Sublicensee of a milestone event for which Curis is obligated to pay a milestone payment to Aurigene under Section 6.6, then only that portion of the milestone payment received by Curis from such Sublicensee that exceeds the amount of the milestone payment Curis is obligated to pay to Aurigene for achievement of such milestone event under Section 6.6 shall be included in Non-Royalty Sublicense Revenues.

(d) Geographic Allocation Mechanism. If Curis grants a sublicense with respect to a Licensed Program in more than one of (i) the US or the EU, (ii) Asia and (iii) one or more other countries in the Curis Territory, then the Non-Royalty Sublicense Revenues received from the applicable Sublicensee under such sublicense shall be allocated amongst the foregoing categories of country in the Curis Territory in proportion to the respective percentage shares of the total pharmaceutical market by sales for all countries covered by such sublicense that are

48.

represented by (A) the country(ies) in category (i) above that are covered by such sublicense, (B) the country(ies) in category (ii) above that are covered by such sublicense, and (C) the country(ies) in category (iii) above that are covered by such sublicense; in each case, as reported by IMS Health (or such other resource as the Parties may mutually agree in writing) for the most recently available calendar year; provided, however, that any item of Non-Royalty Sublicense Revenues received under such sublicense that is unequivocally tied to a particular country or jurisdiction that is entirely within only one of category (i), category (ii) or category (iii) above (e.g., Acceptance for Filing of IND or NDA by the EMA, or Regulatory Approval in Japan) shall be allocated solely to such category ((i), (ii) or (iii), as applicable).

6.10 Third Party Licenses.

(a) In the event that Curis (or its Affiliate or Sublicensee, as applicable) is required to obtain one or more licenses under Patent Rights of Third Parties reasonably necessary (as discussed below) for the manufacture, use or sale of a Product in a country (hereinafter “Third Party Licenses”), [**]% of the royalties actually paid under such Third Party Licenses by Curis (or by such Affiliate or Sublicensee, as applicable) for sale of such Product in such country for a calendar quarter will be creditable against the royalty payments due to Aurigene by Curis with respect to Net Sales of such Product in such country (whether pursuant to Section 6.7 or, if applicable, clause (y) of Section 6.8(a)); provided, however, that in no event will the royalties owed by Curis to Aurigene hereunder with respect to Net Sales of such Product for such calendar quarter be reduced by more than [**]%; and provided, further, that Curis will not be entitled to credit any portion of royalties paid by Curis or its Affiliate or Sublicensee to Third Parties with respect to any Other Active in any Combination Product.

(b) For purposes of this Section 6.10, valid reasons for determining that a license under Patent Rights of a Third Party is “reasonably necessary” for the manufacture, use or sale of a Product in a country shall be limited to the following:

(i) without the practice of the invention(s) claimed by such Patent Rights in the manufacture, use or sale of such Product, the applicable Product would not be commercially viable, would likely be materially less profitable, or would not achieve a commercially reasonable level of market acceptance, in such country; or

(ii) in the absence of a license under such Patent Rights, such Patent Rights would be infringed by the manufacture, use or sale of such Product in such country.

(c) Promptly after Curis or its Affiliate enters into, or receives notice that a Sublicensee has entered into, a Third Party License, Curis shall notify Aurigene in writing of the Patent Rights covered by such Third Party License. If Aurigene in good faith disagrees with the determination by Curis (or its Affiliate or Sublicensee) that such Third Party License is reasonably necessary for the manufacture, use or sale of a Product in a country, Aurigene shall so notify Curis in writing within [**] days after receipt of such notice from Curis, whereupon the Parties shall promptly confer regarding the matter and attempt in good faith to reach consensus for up to [**] days from Curis’ receipt of such notice from Aurigene. If the Parties are unable to reach consensus within such [**]-day period, then the Parties shall submit the matter to an independent Third Party expert with relevant experience in pharmaceutical industry practices

49.

with respect to the in-licensing of patent rights in connection with the commercialization of pharmaceutical products for resolution and sufficient experience and background to evaluate the scope of the patent rights’ validity and enforceability under the Third Party License and whether reasonably necessary for the manufacture, use or sale of a Product in a country, which expert shall be agreed upon by both Parties or, failing such agreement, designated by the International Centre for Dispute Resolution located in New York City, NY. The sole authority of such expert will be to determine whether or not such Third Party License is reasonably necessary for the manufacture, use or sale of such Product in such country, and such expert’s determination shall be final and binding upon the Parties. The independent Third Party expert shall be required to make his or her determination within [**] days after selection of the independent Third Party expert. The Parties shall initially bear the fees and expenses of such expert equally, but the prevailing Party shall reimburse the other Party for the documented fees and expenses of such expert paid by the prevailing Party.

6.11 Compulsory Licenses. If a compulsory license is granted to a Third Party with respect to Product in any country with a royalty rate lower than the applicable royalty rate under clause (y) of Section 6.8(a), then the royalty rate applicable to Net Sales of such Product in that country by such compulsory licensee under clause (y) of Section 6.8(a) shall be reduced to a rate which is [**]%) percentage points (i.e., [**] basis points) less than the rate paid by the compulsory licensee; provided, however, that if the royalty rate payable by the compulsory licensee with respect to Net Sales of such Product in such country is less than [**]%, then the royalty rate under clause (y) of Section 6.8(a) shall be reduced to [**]% of the rate paid by the compulsory licensee, but only with respect to sales or other disposition of Product in that country by that compulsory licensee.

6.12 Adjustment for Generic Competition. On a Product-by-Product and country-by-country basis, if one or more Generic Versions of such Product account for [**]% or more of aggregate unit sales of such Product and such Generic Version(s) in such country in a calendar quarter, as determined by reference to applicable sales data obtained from IMS Health or from such other source for such sales data as may be agreed upon by the Parties (provided that such other source, if any, shall be generally recognized as a reliable source for pharmaceutical sales data among major pharmaceutical companies): (a) if Curis, an Affiliate or a Sublicensee grants rights to a Third Party to commercialize an authorized generic Product (i.e., the same Product marketed without any Product trademarks under the same NDA as the branded Product) where the royalty rate payable by the Third Party on sales or other dispositions of the authorized generic Product is lower than the applicable royalty rate under clause (y) of Section 6.8(a), then the royalty rate applicable to Net Sales of such authorized generic Product in that country by such Third Party under clause (y) of Section 6.8(a) shall be reduced to a rate which is [**] percentage points (i.e., [**] basis points) less than the rate paid by the Third Party; provided, however, that if the royalty rate payable by the Third Party with respect to Net Sales of such authorized generic Product in such country is less than [**]%, then the royalty rate under clause (y) of Section 6.8(a) shall be reduced to [**]% of the rate paid by the Third Party, but only with respect to sales or other disposition of such authorized generic Product in that country by that Third Party; or (b) if Curis, an Affiliate or a Sublicensee reduces its pricing for the applicable branded Product in the applicable country such that the royalties payable to Aurigene with respect to such branded Product in such country results in an unreasonable economic imbalance between the Parties, the Parties shall meet and attempt in good faith to agree to

50.

modified royalty obligations for Curis so as to maintain a reasonable economic balance between the Parties; provided, however, that if the royalty rate payable by such Sublicensee with respect to Net Sales of the branded Product in such country is less than the applicable royalty rate under clause (y) of Section 6.8(a), then the royalty rate applicable to Net Sales of the branded Product in that country by such Sublicensee under clause (y) of Section 6.8(a) shall be reduced to a rate which is [**] percentage points (i.e., [**] basis points) less than the rate paid by such Sublicensee; and provided, further, that if the royalty rate payable by such Sublicensee with respect to Net Sales of the branded Product in such country is less than [**]%, then the royalty rate under clause (y) of Section 6.8(a) shall be reduced to [**]% of the rate paid by such Sublicensee, but only with respect to sales or other disposition of such branded Product in that country by such Sublicensee.

6.13 Royalty Term. Royalties and payments with respect to Sublicensee Royalties shall be payable on a Product-by-Product and country-by-country basis from First Commercial Sale of a Product in a country until the later of (i) 10 years from First Commercial Sale of such Product in such country and (ii) expiration of the last-to-expire Valid Claim of the Aurigene Patent Rights claiming or covering the manufacture, use or sale of such Product or the Program Compound contained therein in such country (the “Royalty Term”); provided, however, that during any portion of the Royalty Term for a Product in a country when there is no Valid Claim of the Aurigene Patent Rights covering the manufacture, use or sale of such Product or the Program Compound contained therein in such country, and where a requirement to pay the full royalty rate would render any payment obligation unenforceable under Applicable Law, Curis’ royalty payment obligations with respect to Curis Net Sales of such Product in such country, or Curis’ minimum royalty payment obligations with respect to Net Sales of such Product by Sublicensees in such country, as applicable, shall be reduced by [**]%. On a Product-by-Product and country-by-country basis, upon expiration of the Royalty Term with respect to a Product in a country, the License with respect to such Product shall become royalty-free, fully-paid, irrevocable and perpetual.

6.14 Royalty Floor. Except as set forth in the provisos to Section 6.12, Curis’ royalty payment obligations with respect to Curis Net Sales of a Product in a country, or Curis’ minimum royalty payment obligations with respect to Net Sales of a Product by Sublicensees in a country, as applicable, shall not be reduced to less than [**]% of the payments that would otherwise be due by reason of any and all deductions, adjustments or reductions that may be available under Sections 6.10, 6.12 and 6.13. For clarity, this Section 6.14 shall not apply to reductions pursuant to Section 6.11.

7. PAYMENTS; RECORDS; AUDITS

7.1 Payment; Reports. Royalties under Section 6.7 shall be calculated for each calendar quarter during the Royalty Term and paid within [**] days after the end of the calendar quarter. Payments under Sections 6.8 and 6.9 shall be calculated and paid within [**] days of receipt by Curis. Each such payment shall be accompanied or preceded by a report of Curis Net Sales, Sublicensee Royalties, Net Sales of Products by Sublicensees, and Non-Royalty Sublicense Revenues in sufficient detail to permit confirmation of the accuracy of the payment made, including the number of Products sold, gross sales, Net Sales of Products and itemized deductions from gross sales (by major category as set forth in the definition of Net Sales), details

51.

of any royalty credits taken pursuant to Section 6.10 on a Third Party Patent License-by-Third Party Patent License basis, any applicable reductions or adjustments made pursuant to Section 6.11, Section 6.12 or Section 6.13, the amounts payable, and the exchange rates used, in each case on a Product-by-Product and country-by-country basis; provided, however, that in the case of gross sales and Net Sales of Products by a Sublicensee, if such Sublicensee does not, despite Curis having used commercially reasonable efforts to obtain such Sublicensee’s agreement to do so under the applicable sublicense agreement, account for or report gross sales, Net Sales or deductions from gross sales on a Product-by-Product and country-by-country basis in certain regions, or does not account for or report deductions from gross sales on an itemized basis, then, in each case, Curis’ report regarding such Sublicensee’s gross sales, Net Sales, and deductions from gross sales need contain only the same level of detail that is reported to Curis by such Sublicensee.

7.2 Exchange Rate; Manner and Place of Payment. All payment amounts in this Agreement are expressed in U.S. dollars, and all payments hereunder shall be payable in U.S. dollars. When conversion of payments from any foreign currency is required, such conversion shall be calculated by applying the average interbank exchange rate as published on xxx.xxxxx.xxx (or such other resource as the Parties mutually agree in writing) for every day within the calendar quarter for which payment is due. All payments owed under this Agreement shall be made by wire transfer in immediately available funds to the bank and account designated in writing by Aurigene.

7.3 Taxes.

(a) In connection with Upfront Equity Issuance.

(i) Curis agrees that the Upfront Equity Issuance shall be made without setoff or counterclaim and free and clear of, and without deduction for, United States federal income Taxes. If any such Taxes are required to be withheld or otherwise paid with respect to the Upfront Equity Issuance, Curis shall timely pay such Taxes and, as promptly as possible thereafter, send to Aurigene an official receipt showing payment thereof, together with such additional documentary evidence as may be reasonably requested by Aurigene. Aurigene shall cooperate with Curis in any way reasonably requested by Curis, to obtain available reductions, credits or refunds of such Taxes. Without limiting the generality of the foregoing, upon request by Curis, Aurigene shall provide Curis such information in Aurigene’s possession as may be reasonably necessary for Curis to obtain the benefit of any applicable reduction in Taxes or any present or future treaty against double taxation which may apply to the Upfront Equity Issuance.

(ii) Curis shall indemnify Aurigene, within [**] days after written demand therefor, for the full amount of any Taxes paid by Aurigene that Curis was obliged to deduct and withhold under Section 7.3(a)(i) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to Curis by Aurigene shall be conclusive absent manifest error.

52.

(b) In connection with all other payments to Aurigene.

(i) Aurigene will pay any and all Taxes levied on account of any payments made to it under this Agreement, other than the Upfront Equity Issuance, and any and all Taxes imposed under the laws of the Republic of India with respect to the transactions contemplated by this Agreement. If any U.S. federal income Taxes are required to be withheld by Curis from any payment made to Aurigene under this Agreement (other than the Upfront Equity Issuance), Curis shall (i) deduct such taxes from the payment made to Aurigene, (ii) timely pay the taxes to the proper taxing authority, (iii) send proof of payment to Aurigene and certify its receipt by the taxing authority within [**] days following such payment, and (iv) cooperate with Aurigene in any way reasonably requested by Aurigene, to obtain available reductions, credits or refunds of such taxes. Without limiting the generality of the foregoing, upon request by Aurigene, Curis shall provide Aurigene such information in Curis’ possession as may be reasonably necessary for Aurigene to obtain the benefit of any applicable reduction in Taxes or any present or future treaty against double taxation which may apply to payments made to Aurigene under this Agreement.

(ii) Aurigene shall indemnify Curis, within [**] days after written demand therefor, for the full amount of any Taxes paid by Curis for which Aurigene is liable under Section 7.3(b)(i) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to Aurigene by Curis shall be conclusive absent manifest error.

7.4 Audits. Curis shall keep (and shall cause its Affiliates and Sublicensees (to the extent applicable) to keep) complete and accurate records pertaining to the sale or other disposition of Products, Sublicensee Royalties and Non-Royalty Sublicense Revenues, in each case, in sufficient detail to permit Aurigene to confirm the accuracy of all royalty and revenue-based payments due under Sections 6.7, 6.8 and 6.9 for at least [**] full calendar years following the end of the calendar year to which they pertain. Aurigene shall have the right, [**], to cause an independent, certified public accountant of international standing and reasonably acceptable to Curis to audit such records solely to confirm Curis Net Sales, Sublicensee Royalties, Net Sales of Products by Sublicensees, Non-Royalty Sublicense Revenues, and royalty and revenue-based payments for a period covering not more than the preceding [**] full calendar years. No calendar year shall be subject to audit under this section more than [**]. Such audits may be exercised during normal business hours upon at least [**] days’ prior written notice to Curis in the location where the records are maintained. The auditor will execute a reasonable written confidentiality agreement with Curis and will disclose to Aurigene only such information as is reasonably necessary to provide Aurigene with information regarding any actual or potential discrepancies between amounts reported and actually paid and amounts payable under this Agreement. The auditor will send a copy of the report to Curis at the same time it is sent to Aurigene. The report sent to both Parties will include the methodology and calculations used to determine the results. Prompt adjustments shall be made by the Parties to reflect the results of such audit. Aurigene shall bear the full cost of such audit unless such audit discloses an underpayment by Curis of more than [**]% of the amount due for any calendar year under this Agreement, in which case, Curis shall bear the full cost of such audit and shall within [**] days remit to Aurigene the amount of any underpayment and late payment interest calculated pursuant to Section 7.5. If such audit discloses an overpayment by Curis, then Curis will deduct the amount of such overpayment from amounts otherwise owed to Aurigene under this Agreement.

53.

7.5 Late Payments. In the event that any payment due under this Agreement is not made when due, the payment shall accrue interest at a rate of [**]% per month for the period from the due date for payment until the date of actual payment; provided, however, that in no event shall such rate exceed the maximum legal annual interest rate. The payment of such interest shall not limit Aurigene from exercising any other rights it may have as a consequence of the lateness of any payment.

8. CONFIDENTIALITY; PUBLICATION

8.1 Confidential Information. Except to the extent expressly authorized by this Agreement, the Receiving Party agrees that, during the Term and for [**] years thereafter, it shall keep confidential and shall not publish or otherwise disclose to any Third Party, and shall not use for any purpose other than as expressly provided for in this Agreement, any Confidential Information of the Disclosing Party. The Receiving Party shall use at least the same standard of care as it uses to protect proprietary or confidential information of its own (but in no event less than reasonable care) to ensure that its, and its Affiliates’, Representatives do not disclose or make any unauthorized use of the Confidential Information. The Receiving Party shall promptly notify the Disclosing Party upon discovery of any unauthorized use or unauthorized disclosure of the Disclosing Party’s Confidential Information.

8.2 Exceptions. Confidential Information shall not include any information which the Receiving Party can prove by competent evidence: (a) is now, or hereafter becomes, through no act or failure to act on the part of the Receiving Party in violation of this Article 8, generally known or available; (b) is known by the Receiving Party or any of its Affiliates at the time of receiving such information, other than being known as a result of disclosure directly or indirectly by the Disclosing Party, as evidenced by its records (provided that the exception in this clause (b) shall not apply to Joint Inventions); (c) is hereafter furnished to the Receiving Party or any of its Affiliates by a Third Party, as a matter of right and without restriction on disclosure; or (d) is independently discovered or developed by the Receiving Party

8.3 or any of its Affiliates, without the use of Confidential Information of the Disclosing Party.

8.4 Authorized Disclosure. Notwithstanding the provisions of Section 8.1, the Receiving Party may disclose Confidential Information of the Disclosing Party as expressly permitted by this Agreement, or if and to the extent such disclosure is reasonably necessary in the following instances:

(a) filing or prosecuting Patent Rights as permitted by this Agreement;

(b) enforcing such Party’s rights under this Agreement and in performing its obligations under this Agreement;

(c) prosecuting or defending litigation as permitted by this Agreement;

54.

(d) complying with applicable court orders, applicable laws, rules or regulations, or the listing rules of any exchange on which the Receiving Party’s securities are traded;

(e) disclosure to Affiliates, actual and potential licensees and sublicensees, employees, consultants or agents of the Receiving Party who have a need to know such information in order for the Receiving Party to exercise its rights or fulfill its obligations under this Agreement, provided, in each case, that any such Affiliate, actual or potential licensee or sublicensee, employee, consultant or agent agrees to be bound by terms of confidentiality and non-use comparable to those set forth in this Article 8; and

(f) disclosure to Third Parties in connection with due diligence or similar investigations by such Third Parties, and disclosure to potential Third Party investors in confidential financing documents, provided, in each case, that any such Third Party agrees to be bound by reasonable obligations of confidentiality and non-use.

Notwithstanding the foregoing, in the event the Receiving Party is required to make a disclosure of the Disclosing Party’s Confidential Information pursuant to Section 8.4(c) or 8.4(d), it will, except where impracticable in the case of requirements of applicable court orders or applicable laws, rules or regulations under Section 8.4(d), (i) give reasonable advance notice to the Disclosing Party of such disclosure, (ii) use efforts to secure confidential treatment of such information at least as diligent as the Receiving Party would use to protect its own confidential information, but in no event less than reasonable efforts, and (iii) cooperate with any efforts by the Disclosing Party, at the Disclosing Party’s request and expense, to secure confidential treatment of such Confidential Information. In any event, the Receiving Party agrees to take all reasonable action to avoid disclosure of Confidential Information hereunder.

8.5 Publications.

(a) Program Technology. If a Party proposes to publish or present any material disclosing Program Technology, such as by oral presentation, manuscript or abstract, that Party will communicate such intent to the SOC and the Patent Team through the Alliance Manager. The Patent Team shall first consider and determine whether any additional patent applications claiming or covering the Program Technology proposed to be disclosed should be made before the Party proposing to make such publication or presentation may proceed. The SOC, in consultation with the Patent Team, shall also discuss in good faith whether the proposed publication or presentation should be made solely by the proposing Party or jointly by the Parties. After determination that all appropriate applications for Program Patent Rights have been filed with respect to the applicable Program Technology, and before any such material is submitted for publication or disclosure, the Party proposing publication or presentation (the “Publishing Party”) shall deliver a complete copy to the other Party and to the Patent Team at least [**] days (except in the case of oral presentation materials and abstracts, which are addressed below) prior to submitting the material to a publisher or initiating such other disclosure, and the non-publishing Party shall review any such material and give their respective comments to the Publishing Party within [**] days of the delivery of such material to the non-publishing Party, which comments shall be considered by the Publishing Party in good faith. With respect to oral presentation materials and abstracts, the Publishing Party shall deliver a

55.

complete copy to the non-publishing Party at least [**] days prior to the anticipated date of the presentation, and the non-publishing Party shall use reasonable efforts to expedite review of such materials and abstracts, and shall return such items as soon as practicable to the Publishing Party with appropriate comments, if any, but in no event later than [**] days from the date of delivery to the non-publishing Party, which comments shall be considered by the Publishing Party in good faith. The Publishing Party shall comply with the non-publishing Party’s requests to delete references to the non-publishing Party’s Confidential Information (other than the applicable Program Technology) in any such material and, if the non-publishing Party or the Patent Team identifies potentially patentable subject matter in such material, agrees to delay any submission for publication or other public disclosure for a period of up to an additional [**] days to allow for the preparation and filing of appropriate patent applications. For clarity, the requirements under this Section 8.5(a) with respect to a Program shall cease in the event Curis’ Option with respect to such Program expires unexercised or is terminated prior to exercise.

Notwithstanding the foregoing, the Parties agree that: (A) no Program Technology from a Program shall be published before the earlier of (1) Curis’ exercise of the Option with respect thereto and (2) expiration of the applicable Option Period if Curis has not exercised such Option prior to such expiration, unless mutually agreed by the Parties in writing; and (B) no unpublished chemical structure of a Program Compound for a Program Target Profile for so long as the Aurigene PTP Exclusivity Obligations with respect to such Program Target Profile are in effect, shall be published without unanimous recommendation of the SOC and applicable Patent Team.

(b) Clinical Trial Results. For clarity, Curis and its Affiliates shall be free to publish, and to authorize Sublicensees to publish, the results of any clinical trial of a Product conducted by or on behalf of Curis, its Affiliate or a Sublicensee, without the prior review or approval of Aurigene.

8.6 Publicity.

(a) Press Releases. No later than one (1) business day following the Effective Date, the Parties shall issue joint press release announcing the execution of this Agreement in substantially the form attached hereto as Exhibit A. It is further acknowledged that each Party may desire or be required to issue subsequent press releases relating to this Agreement or activities hereunder. The Parties agree to consult with each other reasonably and in good faith with respect to the text and timing of subsequent press releases prior to the issuance thereof, provided that a Party may not withhold consent to such releases that the other Party may determine, based on advice of counsel, are reasonably necessary to comply with Applicable Laws, including disclosure requirements of the U.S. Securities and Exchange Commission, or with the requirements of any stock exchange on which securities issued by a Party or its Affiliates are traded.

investors or those attending industry conferences or financial analyst calls, or issue press releases, so long as the contents of any such public statement or press release are contained in a prior public disclosure or public statement approved by the other Party pursuant to this Section 8.6(a) or permitted by Section 8.4 and does not reveal non-public information about the other Party.

(b) Filing of this Agreement. The Parties shall coordinate in advance with each other in connection with the filing of this Agreement (including redaction of certain provisions of this Agreement) with any securities authority or with any stock exchange on which securities issued by a Party or its Affiliate are traded, and each Party will use reasonable efforts to seek and obtain confidential treatment for the terms proposed to be redacted; provided that each Party will ultimately retain control over what terms are disclosed to any securities authority or stock exchange, as the case may be, to the extent such Party determines, on the advice of legal counsel, that disclosure is reasonably necessary to comply with Applicable Laws, including disclosure requirements of the U.S. Securities and Exchange Commission, or with the requirements of any stock exchange on which securities issued by a Party or its Affiliates are traded, and provided further that the Parties will use their reasonable efforts to file redacted versions with any governing bodies which are consistent with redacted versions previously filed with any other governing bodies.

(a) Aurigene Patent Rights.

(i) Prior to Option Exercise. On a Program-by-Program basis prior to Curis’ exercise of the Option for a Program, Aurigene shall take the lead in prosecuting and maintaining the Aurigene Patent Rights (including Program Patent Rights and Joint Patent Rights) relevant to such Program, at its sole cost and expense using outside counsel reasonably acceptable to Curis, in accordance with the patent prosecution strategy recommended by the Patent Team for such Program. Aurigene and its outside patent counsel shall prepare proposed patent applications in close consultation with Curis’ Patent Team representative and Curis’ outside patent counsel. All patent applications and other material patent office submissions with respect to any such Patent Right will be subject to review and comment by Curis and its outside patent counsel, which comments shall be considered in good faith by Aurigene. If Aurigene

59.

plans not to make any national phase filing in any country, or to abandon any such Aurigene Patent Right in any particular country, in the Curis Territory, Aurigene will notify Curis in writing at least [**] days in advance of the due date of any payment or other action that is required to prosecute and maintain such Aurigene Patent Right in such country and, upon such notice, Curis shall have the right, but not the obligation, to assume responsibility for prosecution and maintenance of such Aurigene Patent Right in such country at its sole cost and expense. This Section 10.3(a)(i) shall cease to apply to an Aurigene Patent Right that is relevant to a Program in the event Curis’ Option with respect to such Program expires unexercised or is terminated prior to exercise.

(ii) After Option Exercise. On a Licensed Program-by-Licensed Program basis after Curis’ exercise of the Option for a Program and during the term of such License, Curis shall have the first right, but not the obligation, to prosecute and maintain any Aurigene Patent Rights (including Program Patent Rights and Joint Patent Rights) relevant to such Licensed Program in the Curis Territory at its sole cost and expense using counsel reasonably acceptable to Aurigene, in accordance with the patent prosecution strategy recommended by the Patent Team for such Licensed Program, and subject to review and comment from Aurigene, which comments shall be considered in good faith by Curis. If Curis plans not to make any national phase filing in any country or, to abandon or cease prosecution or maintenance of any such Patent Right in any particular country, in the Curis Territory, Curis shall so notify Aurigene in writing at least [**] days in advance of the due date of any payment or other action that is required to prosecute and maintain such Patent Right in such country and, upon such notice, Aurigene shall have the right, but not the obligation, to assume responsibility for prosecution and maintenance of such Patent Right at its sole cost and expense, and if Aurigene elects to continue prosecution of such Patent Right in such country, all licenses granted to Curis under such Patent Right (or, as applicable, under Aurigene’s interest in such Patent Right) in such country will be terminated.

(b) Joint Patent Rights. Except in the case of Joint Patent Rights that are subject to Section 10.3(a) (which shall be governed solely by Section 10.3(a)), Aurigene shall have the first right, but not the obligation, to prosecute and maintain Joint Patent Rights in the Aurigene Territory, at its sole cost and expense and by counsel of its own choice, and Curis shall have the first right, but not the obligation, to prosecute and maintain Joint Patent Rights in the Curis Territory, at its sole cost and expense and by counsel of its own choice, in each case in accordance with the patent prosecution strategy approved by the Patent Team for such Joint Patents. Each Party shall keep the other party reasonably informed of progress with regard to the prosecution and maintenance of Joint Patent Rights for which such Party (the “Responsible Party”) is responsible, and shall consult with, and consider in good faith the requests and suggestions of, the other Party with respect to strategies for filing and prosecuting Joint Patent Rights worldwide. In the event that the Responsible Party desires not to file, or desires to abandon or cease prosecution or maintenance of, any Joint Patent Right in any country, the Responsible Party shall provide reasonable prior written notice to the other Party of such intention not to file, or to abandon or cease prosecution or maintenance (which notice shall, to the extent possible, be given no later than [**] days prior to the next deadline for any action that must be taken with respect to any such Joint Patent Right in the relevant patent office). In such case, at the other Party’s sole discretion, upon written notice to the Responsible Party from the other Party, the other party may elect to continue prosecution or maintenance of any such Joint Patent Right, at its sole cost and expense and by counsel of its own choice.

60.

10.4 Cooperation of the Parties. Each Party agrees to cooperate fully in the prosecution and maintenance of Patent Rights under Section 10.3 and in the obtaining and maintenance of any patent extensions, supplementary protection certificates and the like with respect thereto respectively at its own costs. Such cooperation includes, but is not limited to: (a) executing all papers and instruments, or requiring its employees or contractors, to execute such papers and instruments, so as to effectuate the ownership of Inventions set forth in Section 10.1, and Patent Rights claiming or disclosing such Inventions, and to enable the other Party to apply for and to prosecute patent applications in any country as permitted by Section 10.3; and (b) 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 applications.

10.5 Infringement by Third Parties.

On a Program-by-Program basis prior to Curis’ exercise of the Option for a Program, neither Party shall bring any action or proceeding against any Third Party for infringement of any Aurigene Patent Right (including any Program Patent Right or Joint Patent Right) relevant to such Program, without the prior written consent of the other Party. Any determination of how to proceed against such Third Party shall require mutual written agreement of the Parties. This Section 10.5(b)(i) shall cease to apply to an Aurigene Patent Right that is relevant to a Program in the event Curis’ Option with respect to such Program expires unexercised or is terminated prior to exercise.

(ii) After Option Exercise. On a Licensed Program-by-Licensed Program basis after Curis’ exercise of the Option for a Program, Curis shall have the first right, but not the obligation, to bring and control any action or proceeding against a Third Party for infringement of any Aurigene Patent Right (including any Program Patent Right or Joint Patent Right) relevant to such Licensed Program in the Curis Territory with respect to any infringing activity that is competitive with a Program Compound or Product, at its own expense and by counsel of its own choice, and Aurigene shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. If Curis fails to bring any such action or proceeding within (A) [**] days following its learning of alleged infringement, or (B) [**] days before the time limit, if any, set forth in the appropriate laws and regulations for the filing of such actions, whichever comes first, then Aurigene shall have the right to bring and control any such action, at its own expense and by counsel of its own choice, and Curis shall have the right, but not the obligation, at its own expense, to be represented in any such action by counsel of its own choice.

61.

(c) Curis Patent Rights. On a Licensed Program-by-Licensed Program basis after Curis’ exercise of the Option for a Program, Aurigene shall have the first right, but not the obligation, to bring and control any action or proceeding against a Third Party for infringement of any Curis Patent Right relevant to such Licensed Program in the Aurigene Territory with respect to any infringing activity that is competitive with a Program Compound or Product, at its own expense and by counsel of its own choice, and Curis shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. If Aurigene fails to bring any such action or proceeding within (A) [**] days following its learning of alleged infringement, or (B) [**] days before the time limit, if any, set forth in the appropriate laws and regulations for the filing of such actions, whichever comes first, then Curis shall have the right to bring and control any such action, at its own expense and by counsel of its own choice, and Aurigene shall have the right, but not the obligation, at its own expense, to be represented in any such action by counsel of its own choice.

Neither Party shall enter into any settlement or compromise of any action under this Section 10.5 which would in any manner alter, diminish, or be in derogation of the other Party’s rights under this Agreement without the prior written consent of such other Party, which shall not be unreasonably withheld. Except as otherwise agreed by the Parties in connection with a cost-sharing arrangement, any recovery realized by a Party as a result of any action or proceeding pursuant to this Section 10.5, whether by way of settlement or otherwise, shall be retained by the Party that brought and controlled such action for purposes of this Agreement; provided, however, that each Party shall be reimbursed for any of its litigation expenses, and any recovery realized by Curis as a result of any action pursuant to Section 10.5(b)(ii) (after reimbursement of the Parties’ litigation expenses) with respect to infringing activity in the Curis Territory, shall be treated as Sublicensee Royalties in the applicable portion of the Curis Territory, and Curis shall pay Aurigene the applicable percentage of such recovery in accordance with Section 6.8, calculated assuming the time of Sublicense grant occurred on the date such recovery was received.

62.

(a) Aurigene Patent Rights. On a Licensed Program-by-Licensed Program basis after Curis’ exercise of the Option for a Program, Curis shall have the right to determine the Aurigene Patent Rights (including Program Patent Rights and Joint Patent Rights) for which it will apply for patent extension in any country or region of the Curis Territory for any Product from such Licensed Program. Curis shall file for any such extension at Curis’ cost and expense. Aurigene shall provide all reasonable assistance to Curis in connection with such filings, provided that Curis shall pay or reimburse any out-of-pocket costs incurred by Aurigene in providing such assistance.

(b) Curis Patent Rights.

11.1 Term. The term of this Agreement (the “Term”) shall begin on the Effective Date and, unless earlier terminated in accordance with this Article 11, expire upon either: (a) 90 days after expiration of the Research Term if Curis has not exercised its Option with respect to at least one Program by such time; or (b) expiration of the last-to-expire Royalty Term for any and all Products.

63.

11.2 Termination for Material Breach.

(a) Material Breach Other Than Failure to Use Diligence. Subject to Section 11.2(c), and except in the case of a material breach covered by Section 11.2(b), each Party shall have the right, in the event of material breach of this Agreement by the other Party, to terminate this Agreement in its entirety, or to terminate this Agreement in part solely with respect to the affected Program or Licensed Program, as applicable, upon written notice to the other Party if such other Party is in material breach of this Agreement and has not cured such breach within [**] days (or [**] days with respect to any payment breach) after notice from the terminating Party requesting cure of the breach. Any such termination shall become effective at the end of such [**]-day (or [**]-day with respect to any payment breach) period unless the breaching Party has cured such breach prior to the end of such period. For clarity, in the event of any such uncured material breach affecting a particular Program or Licensed Program, such termination shall apply only to the affected Program or Licensed Program, and this Agreement shall otherwise remain in full force and effect. Notwithstanding the foregoing or Section 11.6 to the contrary, but without limiting Aurigene’s rights under Section 11.2(b)(ii), after Initiation of the first Pivotal Trial of a Product for a Licensed Program, Aurigene may not terminate this Agreement pursuant to this Section 11.2(a) with respect to such Licensed Program, except in the case of uncured material payment breach by Curis with respect to such Licensed Program, but for clarity, Aurigene may pursue any and all remedies that may be available to it at law or in equity as a result of such breach by Curis. Notwithstanding the foregoing or Section 11.6 to the contrary, after Initiation of the first Pivotal Trial of a Product for a Licensed Program, Curis may not terminate this Agreement pursuant to this Section 11.2(a) with respect to the Aurigene Territory License for such Licensed Program, but for clarity, Curis may pursue any and all remedies that may be available to it at law or in equity as a result of such breach by Aurigene.

(b) Material Breach of Diligence Obligations.

(i) Material Breach by Aurigene. On a Program-by-Program basis, if Curis in good faith believes that Aurigene has failed to comply with its obligations under Section 3.3 with respect to a Program or under Section 5.8(a) with respect to a Licensed Program, Curis shall notify Aurigene and, within [**] days thereafter, Curis and Aurigene will meet and confer to discuss the matter in good faith and attempt to agree upon a mutually agreeable plan to address issues related to such failure by Aurigene. Following such meeting, if either (A) the Parties do not agree upon a plan to address such failure by Aurigene within the foregoing [**]-day period, or (B) Aurigene fails to comply with its obligations under any mutually agreed upon plan to address such failure by Aurigene, then subject to Section 11.2(c) below, Curis will have the right, at its sole discretion, to terminate this Agreement as it relates to such Program or Licensed Program, as applicable.

(ii) Material Breach By Curis. On a Program-by-Program basis, if Aurigene in good faith believes that Curis has failed to comply with its obligations under Section 5.8(b) with respect to a particular Licensed Program, Aurigene shall notify Curis and, within [**] days thereafter, Curis and Aurigene will meet and confer to discuss the matter in

64.

good faith and attempt to agree upon a mutually agreeable plan to address issues related to such failure by Curis. Following such meeting, if either (A) the Parties do not agree upon a plan to address such failure by Curis within the foregoing [**]-day period, or (B) Curis fails to comply with its obligations under any mutually agreed upon plan to address such failure by Curis, then subject to Section 11.2(c) below, Aurigene will have the right, at its sole discretion, to terminate this Agreement as it relates to such Licensed Program.

(c) Dispute Regarding Breach. Any right to terminate this Agreement, in its entirety or with respect to a particular Program or Licensed Program, as applicable, under this Section 11.2 shall be stayed and the cure period tolled in the event that, during any cure period, the Party alleged to have been in material breach shall have initiated dispute resolution in accordance with Article 13 with respect to the alleged breach, which stay and tolling shall continue until such dispute has been resolved in accordance with Article 13.

11.3 Alternative to Curis Termination for Aurigene Material Breach. As an alternative to terminating this Agreement in its entirety or as it relates to a particular Program or Licensed Program, as applicable, pursuant to Section 11.2(a) or Section 11.2(b)(i) for Aurigene’s uncured material breach, but for clarity excluding any Licensed Program after Initiation of the first Pivotal Trial of a Product for such Licensed Program, Curis may elect:

(a) not to terminate this Agreement (in its entirety or as it relates to such Program or Licensed Program, as applicable);

(b) to retain its rights under this Agreement (in its entirety or as it relates to such Program or Licensed Program, as applicable), including, if applicable, the Option(s) and its License(s) with respect to Licensed Program(s), subject to all terms and conditions hereof, including Article 6;

(c) to terminate: (i) in the case of a Program with respect to which the Option Period has not expired, Aurigene’s right to obtain the Aurigene Territory License for such Program upon Curis’ exercise of the Option for such Program; or (ii) in the case of a Licensed Program, the Aurigene Territory License for such Licensed Program;

(d) to terminate Article 2, Section 5.5, and the Supply Option as to such Program or Licensed Program;

(e) to assume sole responsibility for all Development Plan activities with respect to such Program or Licensed Program (including IND-enabling studies and CMC activities); and

(f) to pursue any remedy that may be available to Curis at law or in equity as a result of Aurigene’s breach, without prejudice to Curis’ right to terminate this Agreement (in its entirety or as it relates to such Program or Licensed Program, as applicable) at a later date pursuant to Section 11.2(a) or Section 11.2(b)(i) (for that uncured material breach for so long as it remains uncured or any other uncured material breach of this Agreement by Aurigene) or pursuant to Section 11.4.

65.

11.4 At-Will Termination by Curis. Curis shall have the right to terminate this Agreement in its entirety or as it relates to a particular Program or Licensed Program or on a country-by-country basis, for any reason or for no reason at any time upon 60 days’ prior written notice to Aurigene.

11.5 Effect of Expiration. Upon expiration (but not on earlier termination) of this Agreement, all Licenses granted by Aurigene to Curis that were in effect immediately prior to such expiration shall survive on a non-exclusive, royalty-free, fully-paid, irrevocable, perpetual basis.

11.6 Effect of Termination.

(a) Termination Prior to Option Exercise. In the event of termination of this Agreement in its entirety prior to Curis’ exercise of the Option for any Program, or termination of this Agreement as to any Program prior to exercise of the Option for such Program, then, in each case, all rights and licenses granted by each Party to the other Party with respect to such Program under this Agreement (including the Option for such Program) shall automatically terminate and revert to the granting Party.

(b) Effect of Termination on Fully-Paid Licenses. If the Royalty Term with respect to a Product for any Program in any country has expired on or before any termination of this Agreement in its entirety or as to such Program, the License with respect to such Product in such country, as well as the applicable Aurigene Territory License, shall survive such termination of this Agreement.

(c) Termination by Aurigene Pursuant to Section 11.2(a) or 11.2(b)(ii) or by Curis Pursuant to Section 11.4 After Option Exercise. Solely in the event of termination of this Agreement by Aurigene pursuant to Section 11.2(a) or Section 11.2(b)(ii), or by Curis pursuant to Section 11.4, the following provisions of this Section 11.6(c) shall apply to any Program that was a Licensed Program immediately prior to such termination:

(i) Curis’ License with respect to any Licensed Program that is not a Terminated Program, either in the entire Curis Territory or in countries of the Curis Territory outside of the Terminated Region, as applicable, shall continue in full force and effect, subject to all terms and conditions hereof, including Article 6;

(ii) Curis’ License with respect to any Terminated Program, either in the entire Curis Territory or in the Terminated Region, as applicable, shall terminate and revert to Aurigene;

Such license shall be non-exclusive with respect to Curis Patent Rights and exclusive with respect to Curis Know-How. Notwithstanding the foregoing, to the extent the Curis Patent Rights for such Terminated Program include Patent Rights licensed to Curis by a Third Party that are subject to royalty or milestone payment obligations to such Third Party with respect to Program Compounds or Products for such Terminated Program, then Curis shall so notify Aurigene, together with a true, complete and correct description of such royalty and milestone payment

66.

obligations, and the inclusion of such Curis Patent Rights in the license granted to Aurigene under this Section 11.6(c)(iii) for such Terminated Program shall be subject to Aurigene’s agreeing in writing to pay, and promptly paying, all royalty and milestone payments that become due to such Third Party by reason of the development, manufacture or commercialization of such Program Compounds and Products for such Terminated Program by or on behalf of Aurigene or any of its Affiliates or sublicensees in the Curis Territory or the Terminated Region, as applicable;

(v) Curis shall: (A) disclose to Aurigene as soon as reasonably practicable such Curis Technology with respect to Program Compounds and Products for such Terminated Program not previously disclosed to Aurigene as may be necessary or useful to enable Aurigene to practice the license granted under Section 11.6(c)(iii) (and, if applicable, Section 11.6(c)(iv)); (B) as promptly as reasonably practicable, transfer and assign to Aurigene all of its and its Affiliates’ right, title and interest in and to all Regulatory Filings and associated correspondence with Regulatory Authorities with respect to Program Compounds and Products for such Terminated Program, either in the Curis Territory or in the Terminated Region, as applicable (or, if Applicable Law prevents or delays the transfer of ownership of any such Regulatory Filing to Aurigene, Curis shall grant, and does hereby grant, to Aurigene an exclusive and irrevocable right of access and reference to such Regulatory Filing for Program Compounds and Products from such Terminated Program, either in the Curis Territory or in the Terminated Region, as applicable, and shall cooperate fully to make the benefits of such Regulatory Filings available to Aurigene or its designee); and (C) take such other actions and execute such other instruments, assignments and documents as may be necessary to effect the transfer of rights under this Section 11.6(c)(v) to Aurigene;

(vi) any sublicense granted by Curis or its Affiliate to a Sublicensee under the License with respect to a Terminated Program in the Curis Territory or in the applicable Terminated Region (as applicable), shall survive the termination of this Agreement and become a direct license from Aurigene to such Sublicensee, provided that, in the case of termination for Curis’ uncured material breach pursuant to Section 11.2(a) or Section 11.2(b)(ii), such Sublicensee did not cause such uncured material breach of this Agreement, and provided that Aurigene shall have no obligations under such sublicense beyond the obligations expressly set forth in this Agreement;

(vii) Curis shall reasonably cooperate, at Aurigene’s expense, with Aurigene and its designee(s) to facilitate a smooth, orderly and prompt transition of any ongoing manufacturing, development and commercialization activities with respect to Program Compounds or Products for a Terminated Program to Aurigene or its designee(s), in the Curis Territory or the applicable Terminated Region (as applicable);

67.

(viii) Aurigene shall have the right to purchase from Curis, at a purchase price equal to Curis’ fully-burdened manufacturing cost (calculated in accordance with Accounting Standards, consistently applied), any or all available and usable clinical and commercial quantities of Product or Program Compound for a Terminated Program in Curis’ or its Affiliates’ possession or control, within [**] days after receipt of Aurigene’s request, provided that if Curis retains a License to the applicable Licensed Program in any portion of the Curis Territory, Curis shall not be obligated to sell any portion of such supplies that Curis intends to use or commercialize outside the Terminated Region. Any packaging, transport, insurance and other costs for delivery of any such purchased materials to Aurigene or its designee shall be paid by Aurigene;

(ix) if Product or Program Compound for a Terminated Program was being manufactured by any Third Party for Curis prior to termination or Curis had contracts with vendors prior to termination, which contracts are necessary or useful for Aurigene to take over responsibility for the Program Compounds or Products in the Curis Territory, Curis shall (A) provide Aurigene with an introduction to such Third Party contract manufacturer or vendor, (B) deliver to such contract manufacturer or vendor written authorization to contract with Aurigene for the manufacture and supply of such Product or Program Compound and to manufacture and supply such Product or Program Compound to Aurigene for the Curis Territory or the Terminated Region (as applicable) using the Curis Know-How in the possession of such contract manufacturer, or such other services as had been provided to Curis with respect to such Product or Program Compound for the Curis Territory or Terminated Region (as applicable), and (C) if permitted by the agreements with such Third Party contract manufacturer or vendor and to the extent requested in writing by Aurigene, assign such agreements to Aurigene, or the applicable work orders, statements of work or the like under such agreements that are relevant to the applicable Product or Program Compound, or if assignment is not permitted, cooperate with Aurigene in working with the contract manufacturer or vendor to obtain the benefits of such agreements or to enter into a new agreement with the contract manufacturer or vendor. In negotiating agreements with any Third Party contract manufacturer or vendor for services with respect to Program Compounds or Products, Curis shall use commercially reasonable efforts to obtain the agreement of such contract manufacturer or vendor to permit Curis to assign such agreement, or the applicable work order(s), statement(s) of work or the like under such agreements that are relevant to the applicable Product or Program Compound, to Aurigene pursuant to this Section 11.6(c)(ix), and, if Curis does not obtain such contract manufacturer’s or vendor’s agreement to the foregoing, Curis shall use commercially reasonable efforts to obtain such contract manufacturer’s or vendor’s consent to such assignment;

(x) Curis shall, and it hereby does, grant and shall cause to be granted to Aurigene a license in and to any trademarks specific to one or more Products or Program Compounds that Curis or its Affiliate or Sublicensee used with such Product(s) or Program Compound(s) for the Curis Territory or Terminated Region (as applicable). It is understood that such license shall not include the name of Curis or any of its Affiliates or Sublicensees; and

(xi) The applicable Aurigene Territory License shall survive.

68.

11.7 Return of Confidential Information. In the event of termination of this Agreement, each Party shall return (or destroy, as directed by the other Party) all data, files, records and other materials containing or comprising the other Party’s Confidential Information, except to the extent such Confidential Information is necessary or useful for the practice of any License or Aurigene Territory License (as applicable) that survives such termination in accordance with Section 11.6. Notwithstanding the foregoing, each Party will be permitted to retain one copy of Confidential Information of the other Party as necessary to comply with Applicable Law and for the purpose of determining any continuing obligations hereunder.

11.8 Accrued Obligations; Survival. Neither expiration nor any termination of this Agreement shall relieve either Party of any obligation or liability accruing prior to such expiration or termination, nor shall expiration or any termination of this Agreement preclude either Party from pursuing all rights and remedies it may have under this Agreement, at law or in equity, with respect to breach of this Agreement. In addition, all terms and provisions of this Agreement which would reasonably be expected to survive expiration or termination shall so survive, including the Parties’ rights and obligations under Sections 4.12, 7.4, 7.5, 8.1, 8.2, 8.4, 8.6, 9.3, 9.4, 10.1, 10.3(b), 10.5(d), 10.6, 11.5, 11.6, 11.7, 11.8 and 11.9 and Articles 12, 13 and 14 of this Agreement shall survive expiration or any termination of this Agreement.

11.9 Damages; Relief. Termination of this Agreement shall not preclude either Party from claiming any other damages, compensation or relief that it may be entitled to hereunder.

12. INDEMNIFICATION

12.1 Indemnification by Curis. Curis hereby agrees to save, defend, indemnify and hold harmless Aurigene, its Affiliates, its and their respective officers, directors, agents, employees, successors and assigns (the “Aurigene Indemnitees”), from and against any and all losses, damages, liabilities, expenses and costs, including reasonable legal expense and attorneys’ fees (“Losses”), to which any Aurigene Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third Party (each, a “Claim”) to the extent such Losses arise out of or relate to (a) the development, manufacture, use, handling, storage, sale, offer for sale, import or other disposition by or on behalf of Curis or any of its Affiliates or Sublicensees of any Program Compound or Product in or for the Curis Territory, (b) the gross negligence or willful misconduct of any Curis Indemnitee (defined below), or (c) the breach by Curis of any warranty, representation, covenant or agreement made by Curis in this Agreement; except, in each case, to the extent such Losses result from the gross negligence or willful misconduct of any Aurigene Indemnitee or the breach by Aurigene of any warranty, representation, covenant or agreement made by Aurigene in this Agreement.

12.2 Indemnification by Aurigene. Aurigene hereby agrees to save, defend, indemnify and hold harmless Curis, its Affiliates and their respective officers, directors, employees, consultants and agents (the “Curis Indemnitees”) from and against any and all Losses to which any Curis 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 relate to (a) the development, manufacture, use, handling, storage, sale, offer for sale, import or other disposition by or on behalf of Aurigene or any of its Affiliates, licensees or sublicensees of any Program Compound or Product in or for the Aurigene Territory, other than such activities

69.

pursuant to a Development Plan, (b) the gross negligence or willful misconduct of any Aurigene Indemnitee, or (c) the breach by Aurigene of any warranty, representation, covenant or agreement made by Aurigene in this Agreement; except, in each case, to the extent such Losses result from the gross negligence or willful misconduct of any Curis Indemnitee or the breach by Curis of any warranty, representation, covenant or agreement made by Curis in this Agreement.

12.3 Control of Defense. In the event a Party (the “Indemnified Party”) seeks indemnification under Section 12.1 or Section 12.2, it shall inform the other Party (the “Indemnifying Party”) of a Claim as soon as reasonably practicable after it receives notice of the Claim (it being understood and agreed, however, that the failure by an Indemnified Party to give notice of a claim as provided in this Section 12.3 shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually damaged as a result of such failure to give notice), shall permit the Indemnifying Party to assume direction and control of the defense of the Claim (including the right to settle the Claim solely for monetary consideration) using counsel reasonably satisfactory to the Indemnified Party, and shall cooperate as requested (at the expense of the Indemnifying Party) in the defense of the Claim. If the Indemnifying Party does not assume control of such defense within [**] days after receiving notice of the Claim from the Indemnified Party, the Indemnified Party shall control such defense and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party shall reimburse the Indemnified Party for all costs, including reasonable attorney fees, incurred by the Indemnified Party in defending itself within [**] days after receipt of any invoice therefor from the Indemnified Party. The Party not controlling such defense may participate therein at its own expense. The Party controlling such defense shall keep the other Party advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the other Party with respect thereto. The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, delayed or conditioned. The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party without the prior written consent of the Indemnified Party.

13. DISPUTE RESOLUTION

13.1 Disputes. Subject to Section 13.3, any claim, dispute, or controversy as to the breach, enforcement, interpretation or validity of this Agreement (each, a “Dispute”) will be referred to the Executives for attempted resolution. In the event such Executives are unable to resolve such Dispute within [**] days of such Dispute being referred to them, then, upon the written request of either Party to the other Party, the Dispute shall be subject to arbitration in accordance with Section 13.2, except as expressly set forth in Section 13.3.

13.2 Arbitration.

(a) Claims. Subject to Section 13.3 below, any Dispute that is not resolved under Section 13.1 within the applicable [**]-day period shall be resolved by final and binding

70.

arbitration administered by the International Centre for Dispute Resolution (the “Administrator”) in accordance with its then-effective International Dispute Resolution Procedures (the “Rules”), except to the extent any such Rule conflicts with the express provisions of this Section 13.2. (Capitalized terms used but not otherwise defined in this Agreement shall have the meanings provided in the Rules.) The Arbitration shall be conducted by one neutral arbitrator selected in accordance with the Rules, provided that such individual shall not be a current or former employee or director, or a current stockholder, of either Party or any of their respective Affiliates (or any licensee or sublicensee of the rights granted to such Party under this Agreement) and shall have at least 15 years of pharmaceutical industry experience. The arbitration and all associated discovery proceedings and communications shall be conducted in English, and the arbitration shall be held in New York, New York, USA if Aurigene requests the arbitration and in Singapore if Curis requests the arbitration.

(b) Discovery. Within [**] days after selection of the Arbitrator, the Arbitrator shall conduct the Preliminary Conference. In addressing any of the subjects within the scope of the Preliminary Conference, the Arbitrator shall take into account both the desirability of making discovery efficient and cost-effective and the needs of the Parties for an understanding of any legitimate issue raised in the Arbitration. In addition, each Party shall have the right to take up to 40 hours of deposition testimony, including expert deposition testimony.

(c) Hearing; Decision. The Hearing shall commence within [**] days after the selection of the Arbitrator. The Arbitrator shall require that each Party submit concise written statements of position and shall permit the submission of rebuttal statements, subject to reasonable limitations on the length of such statements to be established by the Arbitrator. The Hearing shall be no longer than five business days in duration. The Arbitrator shall also permit the submission of expert reports. The Arbitrator shall render the Award within [**] days after the Arbitrator declares the Hearing closed, and the Award shall include a written statement describing the essential findings and conclusions on which the Award is based, including the calculation of any damages awarded. The Arbitrator will, in rendering his or her decision, apply the substantive law of the State of New York, USA, excluding its conflicts of laws principles with the exception of sections 5-1401 and 5-1402 of New York General Obligations Law. The Arbitrator’s authority to award special, incidental, consequential or punitive damages shall be subject to the limitation set forth in Section 9.4. The Award rendered by the Arbitrator shall be final, binding and non-appealable, and judgment may be entered upon it in any court of competent jurisdiction.

(d) Costs. Each Party shall bear its own attorney’s fees, costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the arbitrator; provided, however, the Arbitrator shall be authorized to determine whether a Party is the prevailing party, and if so, to award to that prevailing party reimbursement for any or all of its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges, travel expenses, etc.), or the fees and costs of the Administrator and the Arbitrator.

13.3 Court Actions. Nothing contained in this Agreement shall deny either Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be

71.

filed and maintained notwithstanding any ongoing discussions between the Parties or any ongoing arbitration proceeding. In addition, either Party may bring an action in any court of competent jurisdiction to resolve disputes pertaining to the validity, construction, scope, enforceability, infringement or other violations of Patent Rights or other intellectual property rights, and no such claim shall be subject to arbitration pursuant to Section 13.2.

14. MISCELLANEOUS

14.1 Rights Upon Bankruptcy. All rights and licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n) of Title 11 of the United States Code and other similar laws in any jurisdiction outside the US (collectively, the “Bankruptcy Laws”), licenses of rights to be “intellectual property” as defined under the Bankruptcy Laws. If a case is commenced during the Term by or against a Party under Bankruptcy Laws then, unless and until this Agreement is rejected as provided in such Bankruptcy Laws, such Party (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) shall perform all of the obligations provided in this Agreement to be performed by such Party. If a case is commenced during the Term by or against a Party under the Bankruptcy Laws, this Agreement is rejected as provided in the Bankruptcy Laws and the other Party elects to retain its rights hereunder as provided in the Bankruptcy Laws, then the Party subject to such case under the Bankruptcy Laws (in any capacity, including debtor-in-possession) and its successors and assigns (including a Title 11 trustee), shall provide to the other Party copies of all Information necessary for such other Party to prosecute, maintain and enjoy its rights under the terms of this Agreement promptly upon such other Party’s written request therefor. All rights, powers and remedies of the non-bankrupt Party as provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including the Bankruptcy Laws) in the event of the commencement of a case by or against a Party under the Bankruptcy Laws.

14.4 Non-Waiver. The failure of a Party to insist upon strict performance of any provision of this Agreement or to exercise any right arising out of this Agreement shall neither impair that provision or right nor constitute a waiver of that provision or right, in whole or in part, in that instance or in any other instance. Any waiver by a Party of a particular provision or right shall be in writing, shall be as to a particular matter and, if applicable, for a particular period of time and shall be signed by such Party.

72.

14.5 Assignment. Except as expressly provided hereunder, neither this Agreement nor any rights or obligations hereunder may be assigned or otherwise transferred by either Party without the prior written consent of the other Party (which consent shall not be unreasonably withheld); provided, however, that either Party may assign this Agreement and its rights and obligations hereunder without the other Party’s consent:

(a) in connection with the transfer or sale of all or substantially all of the business of such Party to which this Agreement relates to a Third Party (“Third Party Acquirer”), whether by merger, sale of stock, sale of assets or otherwise (each, a “Sale Transaction”), provided that in the event of a Sale Transaction (whether this Agreement is actually assigned or is assumed by the Third Party Acquirer or the surviving corporation resulting from such Sale Transaction by operation of law (e.g., in the context of a reverse triangular merger)), intellectual property rights of the Third Party Acquirer that existed prior to the Sale Transaction shall not be included in the technology licensed hereunder or otherwise subject to this Agreement; or

(b) to an Affiliate, provided that the assigning Party shall remain liable and responsible to the non-assigning Party hereto for the performance and observance of all such duties and obligations by such Affiliate.

Any assignment not in accordance with this Agreement shall be void.

14.6 Force Majeure. Each Party shall be excused from liability for the failure or delay in performance of any obligation under this Agreement by reason of any event beyond such Party’s reasonable control, including but not limited to Acts of God, fire, flood, explosion, earthquake, or other natural forces, war, civil unrest, acts of terrorism, accident, destruction or other casualty, any lack or failure of transportation facilities, any lack or failure of supply of raw materials, any strike or labor disturbance, or any other event similar to those enumerated above. Such excuse from liability shall be effective only to the extent and duration of the event(s) causing the failure or delay in performance and provided that the Party has not caused such event(s) to occur. The affected Party shall notify the other Party of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake all reasonable efforts necessary to cure such force majeure circumstances.

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