In addition, the provisions of Section 8.5 hereof shall survive the expiration of the term of this Agreement pursuant to clause (ii) of Section 13.1 hereof so as to cover and apply to any Third Party Infringement Claim that arises after such expiration and that is based on infringement of a Knowable Patent.

14.1. Disputes. The Parties recognize that disputes as to certain matters may from time to time arise during the term of this Agreement which relate to either Party’s rights and/or obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Section 14.1 if and when a dispute arises under this Agreement. Business issues that are not contractual disputes arising under this Agreement shall be discussed by the JCT at the request of either party. Any contractual dispute arising under this Agreement shall be discussed first by the JCT. In the event that the JCT is unable to resolve any such contractual dispute within thirty (30) days after such contractual dispute is submitted to the JCT, then any such contractual dispute shall, by either Party providing written notice to the other Party, be referred to the respective chief executive officers of the Parties for attempted resolution by good faith negotiations within thirty (30) days after such notice is received. In the event that the designated officers are not able to resolve such dispute within such thirty (30) day period, and do not agree to extend the time period for resolving the dispute, or if the terms and conditions of the resolution or settlement of the dispute are breached, the dispute shall be submitted for mediation by a mutually acceptable Third Party within thirty (30) days after expiration of the previous thirty (30) day period, unless the Parties agree to extend the period for submitting the contractual dispute for mediation. In the event that such contractual dispute is not resolved within thirty (30) days after such contractual dispute is submitted for mediation, unless the parties otherwise agree to extend the time period for resolving the dispute, then such contractual dispute shall be resolved by arbitration pursuant to the provisions of Section 14.2. Pending resolution of any dispute covered by this Section 14.1, both Parties will continue their performance under this Agreement and the Supply Agreement of any obligations (including, without limitation, payment obligations) that are not the subject of such dispute.

14.2. Arbitration. If the dispute is not resolved pursuant to Section 14.1 above, then the Parties shall follow the procedures set forth below.

14.3. Governing Law; Judicial Resolution. Resolution of all disputes arising out of or related to this Agreement or the performance, enforcement, breach or termination of this Agreement and any remedies relating thereto, shall be governed by and construed under the

substantive laws of the United States of America and the State of New York, as applied to Agreements executed and performed entirely in the State of New York by residents of the State of New York, without regard to conflicts of law rules. Any dispute arising under this Agreement shall be submitted to a state or federal court of competent jurisdiction, except as otherwise expressly provided in this Agreement.

14.4. Equitable Remedies; Injunctive Relief. Nothing in this Article 14 shall prohibit either Party from seeking or obtaining any equitable remedy, including, but not limited to, injunctive relief, from a court or government agency of competent jurisdiction.

**14.5. [*]** If a dispute is submitted to arbitration in accordance with Section 14.2 in connection with any alleged breach of this Agreement by [], provided however, [] pursuant to this Agreement [] that relates to such dispute. [] after such dispute is submitted to arbitration [*] final determination of the arbitration or upon mutual agreement of Cubist and Chiron.

14.6. Interest. All amounts owed by either Party to the other Party in connection with any breach of this Agreement or the Supply Agreement shall bear interest at the rate stipulated in Section 7.10 hereof for late payments.

There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties other than as are set forth herein and therein. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party.

15.2. Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by force majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting force majeure continues and the nonperforming Party uses reasonable efforts to remove the condition. For purposes of this Agreement, force majeure shall include conditions beyond the control of the parties, such as an act of God, voluntary or involuntary compliance with any regulation, law or order of any government, war, an act of terrorism, civil commotion, labor strike or lock-out, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe; provided, however, the payment of invoices due and owing hereunder shall not be delayed by the payer because of a force majeure affecting the payer.

15.3. Notices. Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to this Agreement and shall be deemed to have been sufficiently given for all purposes if mailed by first class certified or registered mail, postage prepaid, express delivery service or personally delivered, or if sent by facsimile, electronic transmission confirmed. Unless otherwise specified in writing, the mailing addresses of the Parties shall be as described below.

15.4. Maintenance of Records. Each Party shall keep and maintain all records required by law or regulation with respect to Licensed Products and shall make copies of such records available to the other Party upon request.

15.6. Assignment.

15.7. Performance by Affiliates. Each of Cubist and Chiron acknowledge that obligations under this Agreement may be performed by Affiliates of Cubist and Chiron. Each of Cubist and Chiron guarantee performance of this Agreement by its Affiliates.

15.8. Guaranty. Chiron Parent Company hereby unconditionally and irrevocably guarantees, as primary obligor, to Cubist, the due and punctual payment and performance as and when due of the obligations, responsibilities, undertakings, representations, warranties, payment covenants, obligations and agreements of Chiron and its Affiliates under this Agreement, the Supply Agreement and any other agreement regarding Licensed Products.

15.9. Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

15.10. Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

15.11. Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, the provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized.

15.12. Headings. The headings for each article and section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular article or section.

15.13. No Waiver. Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter for a particular period of time.

(a) Formation. Within thirty (30) days after the Effective Date, Cubist and Chiron shall establish the Joint Coordination Team (the “JCT”), which shall (i) serve as a forum for the review and discussion of the Parties’ efforts under this Agreement including the development and marketing and sales activities in the Territory and outside the Territory with respect to Licensed Products, and (ii) serve as a forum for the resolution of disputes between the Parties in accordance with the provisions of Article 15 of this Agreement.

(b) Membership. Cubist and Chiron each shall designate an equal number of representatives (but in no event more than four (4) representatives each) with appropriate expertise to serve as members of the JCT. Of the initial representatives to be designated by each Party, there shall be expertise in regulatory matters, clinical development matters, and sales and marketing matters.

(d) Specific Activities. In addition to its functions described in Section 3.2(a), the JCT shall in particular review, consider, discuss and comment upon where appropriate:

(e) Limited Authority; Not a Decision-Making Body.

(f) Meeting Agendas. Each Party will disclose to the other Party its final agenda items along with appropriate related information at least ten (10) business days in advance of each meeting of the JCT.

(a) Territory Specific Studies. The Parties acknowledge that Regulatory Authorities in the Territory may require that certain clinical studies be conducted in connection with Regulatory Approval sought in the Territory by Chiron, but which studies are not required by the FDA or any other Regulatory Authorities outside the Territory (the “Territory Specific Studies” and each a “Territory Specific Study”). Chiron shall use Commercially Reasonable Efforts to conduct the Territory Specific Studies provided that Chiron shall be entitled to decline to perform any Territory Specific Study if, in its sole discretion, it considers the study to be prohibitively expensive, uneconomical or not in its commercial interest. If Chiron elects not to conduct any particular Territory Specific Study, it will notify Cubist in writing of its reasons therefor and discuss same at a meeting of the JCT. If the Parties are unable to reach an agreement on cost sharing to conduct such Territory Specific Study, Chiron shall have no further obligation to conduct such Territory Specific Study.

(b) Proposed Indications. Chiron may, from time to time, propose to Cubist through the JCT that Cubist consider pursuing development for a new indication (the “Proposed Indication”). Such proposal shall be in writing and contain such information as may be readily gathered which will assist Cubist to evaluate the proposal on its merits. If after due consideration by Cubist and Chiron at the JCT, consensus is reached to pursue development for such new indication, Cubist shall add the Proposed Indication to the Cubist Development Plan. In the event that the Parties are unable to reach consensus on adding the Proposed Indication then Chiron shall be free to pursue, at its own expense, development of such Proposed Indication.

(c) Medical Affairs Studies. Chiron may conduct Medical Affairs Studies of the Licensed Products at its sole cost and expense. Chiron shall provide to Cubist via the JCT its proposal for any Medical Affairs Study it wishes to conduct, for review and discussion purposes only. Cubist shall supply Licensed Products to be used in Medical Affairs Studies (i) at a

(d) Chiron Development Plan. Chiron will prepare and update annually a development plan for Chiron’s development activities pursuant to this Section 4.3 (the “Chiron Development Plan”). Chiron shall update the Chiron Development Plan each year to reflect the activities that Chiron expects to conduct during the following calendar year and Chiron shall provide the updated Chiron Development Plan to Cubist prior to the JCT’s last scheduled meeting during the then current year. Cubist shall have the right to review and comment, via the JCT, on the Chiron Development Plan and any and all revisions or updates thereto and Chiron shall, in good faith, consider all comments made by Cubist. Subject to the provisions set forth below in this Section 4.3(d), Chiron shall use Commercially Reasonable Efforts to carry out and perform during each calendar year the activities set forth in the Chiron Development Plan, as may be in effect for such calendar year, that are materially significant for obtaining Regulatory Approval in the Territory. With the exception of the Territory Specific Studies (which Chiron may decline to perform in accordance with the provisions of Section 4.3(a) above), Chiron reserves the right at any time to change or modify the Chiron Development Plan or any of the preclinical studies or clinical trials described in the Chiron Development Plan, or to abandon any portion of the Chiron Development Plan or discontinue any such preclinical studies or clinical trials, in response to (i) changes in clinical or regulatory strategy of either Chiron or Cubist, (ii) regulatory feedback, (iii) scientific feasibility, (iv) increases in the anticipated costs of clinical trials, (v) any significant adverse event or condition relating to the safety or efficacy of a Licensed Product, (vi) manufacturing feasibility, including, without limitation, changes in the anticipated costs of manufacturing and/or procuring Licensed Product, (vii) significant adverse changes in market conditions or in market potential of a drug candidate, or (viii) any other reason that Chiron determines in its reasonable discretion justifies such change, modification, abandonment or discontinuation; however, prior to making any decision to abandon any development effort (or change or modify any such effort so as to effectively abandon same), Chiron shall have first provided its reasons in support of such decision to Cubist via the JCT and the JCT shall have met to discuss the merits of such decision. The exercise by Chiron of any right that it may have under this Section 4.3(d) to change, modify, abandon or discontinue all or any portion of the Chiron Development Plan or any of the preclinical studies or clinical trials described in the Chiron Development Plan shall not relieve Chiron from its obligations to use Commercially Reasonable Efforts under Section 5.1 or Section 6.1 hereof.

(e) Limitation on Chiron’s Development Rights. Notwithstanding anything in this Section 4.3 to the contrary, in the event that at any time Cubist reasonably believes, on the basis of medical, clinical, scientific and other data, facts and knowledge that have been published or are otherwise documented and available or are known to subject matter experts, and presented to Chiron, that any of the development activities being conducted or to be conducted by Chiron pursuant to this Section 4.3 is substantially likely to result in Global Harm, Cubist shall promptly convene a meeting of the JCT to discuss same. Prior to the meeting, Cubist will provide to Chiron all relevant documents, materials and information suggesting the likelihood of Global Harm as well as Cubist’s recommendations to Chiron on the course of action (e.g. modify the

(a) Information Sharing. Chiron will provide to Cubist all Information that results from any development activities conducted pursuant to Section 4.3 above or the Chiron Development Plan (the “Chiron Data”). Subject to Section 4.4(c), any such Chiron Data so provided shall be strictly for information purposes only and Cubist shall have no right to use the Chiron Data for any purpose whatsoever, including without limitation, to access, reference, interpret, disclose, tabulate, analyze or otherwise use any such Chiron Data for the purpose of supporting any Drug Approval Application anywhere in the world.

(b) Reciprocating Licensee. Cubist may share the Chiron Data with any Other Licensee who has agreed in writing to permit reciprocal sharing by Cubist with Chiron of the results of such Other Licensee’s own development activities in accordance with the provisions of Section 5.3 hereof (each a “Reciprocating Licensee”), provided that Cubist has first communicated the restrictions set forth in this Section 4.4 on use of the Chiron Data and obtained the Reciprocating Licensee’s written agreement to abide by such restrictions.

(c) License Option. Chiron hereby grants to Cubist an option to acquire a nonexclusive license on commercially reasonable terms (as to which the Parties shall agree thereon at any time on or prior to the date of the exercise of the option) to access, reference, interpret, disclose, tabulate, analyze or otherwise use all Chiron Data for the purpose of supporting Drug Approval Applications in any country outside the Territory. The Parties contemplate that such license will include a right of Cubist to grant sublicenses to any Reciprocating Licensee who agrees in writing to grant a reciprocal option to Cubist to acquire a nonexclusive license on commercially reasonable terms (as to which such Reciprocating Licensee and Cubist shall agree thereon at any time on or prior to the date of the exercise of the option) to access, reference, interpret, disclose, tabulate, analyze or otherwise use all similar development data of such Reciprocating Licensee for the purpose of supporting Drug Approval

(a) Cubist’s and Other Licensees’ Activities. Cubist shall prepare and present to Chiron via the JCT, and update annually, its regulatory plan for the Licensed Products outside of the Territory. Cubist shall keep Chiron apprised of the status of Cubist’s and the Other Licensees’ efforts to obtain Regulatory Approval in countries outside of the Territory. Prior to making any decision to abandon any efforts and activities set forth in such regulatory plan to obtain Regulatory Approval in the United States for a Licensed Product (or for an indication or formulation of same), Cubist shall have first provided its reasons in support of such decision to Chiron via the JCT and the JCT shall have met to discuss the reasons for such decision.

(b) Regulatory Plan. Within the time period set forth in Section 5.1(c)(i), Chiron shall prepare and deliver to Cubist one regulatory plan for the Territory, which regulatory plan shall set forth Chiron’s plan, strategy and proposed activities to obtain Regulatory Approval in the Territory for the Launch Indication(s) (the “Regulatory Plan”). The Regulatory Plan may include, as appropriate and without limitation, the following elements:

(c) Specific Regulatory Activities. Chiron will use Commercially Reasonable Efforts to:

(d) Costs and Expenses. Chiron shall bear all of the costs and expenses in connection with any and all regulatory activities within the Territory engaged in by Chiron and its Affiliates pursuant to, and in accordance with, the provisions of this Section 5.1, it being understood that the foregoing regulatory activities shall not include any activities of Chiron to assist Cubist with its development obligations under this Agreement or outlined in the Cubist Development Plan. Cubist shall bear all of the costs and expenses in connection with any and all regulatory activities engaged in by Cubist and its Affiliates in connection with obtaining and maintaining Regulatory Approval for Licensed Products outside the Territory, regardless of whether such activities occur within the Territory or outside the Territory.

(e) Limitation on Activities. Notwithstanding anything in this Section 5.1 or elsewhere in this Agreement to the contrary, in the event that at any time Cubist reasonably believes on the basis of medical, clinical, scientific and other data, facts and knowledge that have been published or are otherwise documented and available or are known to subject matter experts, and presented to Chiron, that obtaining Regulatory Approval in the Territory for any Licensed Product for any particular indication either: (i) substantially increases the risk that an adverse safety event will occur; or (ii) would result in the use of a Licensed Product to treat an indication for which such Licensed Product is an ineffective or inferior therapeutic alternative and such use would materially adversely affect the development, marketing, distribution or Commercialization of such Licensed Product or any other Licensed Product within or outside the Territory for other indications; Cubist shall promptly convene a meeting of the JCT to discuss same. Prior to the meeting, Cubist will provide to Chiron all relevant documents, materials and information suggesting the likelihood of events described in clauses (i) and (ii) above, as well as Cubist’s recommendations to Chiron on the course of action (e.g., not seeking approval of a particular Licensed Product or not seeking approval of a particular indication, etc.). At the JCT, the Parties will discuss and attempt to reach consensus on the course of action. Following such discussion, in the absence of consensus, Cubist shall have the right to require Chiron to modify or discontinue those regulatory activities that Cubist reasonably and in good faith believes, based on the totality of the data, facts and knowledge presented to Chiron and the data, facts and knowledge presented by Chiron in response, are substantially likely to result in the events described in clause (i) or clause (ii) above in this Section 5.1(e).

(e) Settlement; Allocation of Proceeds. Cubist shall not settle a claim brought under this Section 8.4 involving Cubist Patents, Chiron Patents or Joint Patents in a manner that would limit or restrict the ability of Chiron to sell, or Chiron’s sales of, Licensed Products in the Territory, without the prior written consent of Chiron (which consent shall not be unreasonably withheld or delayed). Chiron shall not settle a claim brought under this Section 8.4 involving Cubist Patents, Chiron Patents or Joint Patents in a manner that would limit or restrict the ability of Cubist to sell, or Cubist’s sales of, Licensed Products outside the Territory, without the prior written consent of Cubist (which consent shall not be unreasonably withheld or delayed). In the event of any recovery of monetary damages from the Third Party in an action brought under Section 8.4(b), Section 8.4(c) or Section 8.4(d), whether such damages result from the infringement of Cubist Patents, Chiron Patents or Joint Patents, such recovery shall be allocated first to the reimbursement of any reasonable expenses incurred by the Parties in the litigation under this Section 8.4 (including, for this purpose, a reasonable allocation of internal counsel), and any remaining amounts (“Remainder”) shall be allocated as follows:

(a) Notice. If any Licensed Product developed, manufactured, used or sold by either Party, its Affiliates, licensees, sublicensees or distributors becomes the subject of a Third Party claim of patent infringement relating to the development, manufacture, use, sale, offer for sale or importation of such Licensed Product, or if either Party reasonably believes, based on facts that such Party has become aware of, that a reasonable potential for any such claim exists, the Party first having notice of such claim or having such reasonable belief shall promptly notify

(b) Avoidance of Infringement. In the event that there is a Third Party Infringement Claim that arises from the use or practice of any Cubist Technology, Chiron Technology or any Joint Technology in connection with the research, development, manufacture, use, sale, offer for sale or importation of Licensed Products in the Territory and/or outside the Territory, the Parties shall confer in good faith as promptly as practicable after both parties become aware of such Third Party Infringement Claim as to whether it is feasible to alter their approach to the infringing activities with respect to the Licensed Product so as to avoid such infringement without adversely affecting their rights under this Agreement. In the event the Parties determine in good faith that it is feasible to alter their approach to such infringing activities without adversely affecting their rights under this Agreement, the Parties shall implement such alternative approach to such infringing activities.

(c) Licensing to Resolve Infringement by Cubist Technology. If the Parties determine in good faith that it is not feasible to alter their approach to any infringing activities referred to in Section 8.5(b) so as to avoid such infringement without adversely affecting their rights under this Agreement, then, if such infringement arises from the use or practice of any Cubist Technology or the research, development, manufacture, use, sale, offer for sale or importation of Licensed Products in the Territory, Cubist shall use commercially reasonable efforts to obtain a license on commercially reasonable terms from the Third Party whose intellectual property rights are being infringed so as to avoid, eliminate, resolve or settle such infringement. In the event that Cubist shall obtain a license from a Third Party pursuant to this Section 8.5(c) in order to avoid, eliminate, resolve or settle any Third Party Infringement Claim of such Third Party and such license consists of or provides rights relating to the development, manufacture, use, sale, offer for sale or import of Licensed Products in the Territory, then Cubist shall sublicense such rights to Chiron for use in the Territory to the same extent that Cubist Technology is licensed by Cubist to Chiron for use in the Territory pursuant to Article 2 hereof, provided that Chiron agrees in writing to make payment, and makes payment when due, to Cubist of the portion of the costs or other amounts paid and required to be paid by Cubist to obtain and maintain such license that are reasonably appropriate for Chiron to bear in light of the relative financial benefits that could reasonably be expected to be derived from such license by Chiron in the Territory, on the one hand, and by Cubist and, if applicable, Third Party licensees of Cubist, outside the Territory, on the other hand. Notwithstanding any provision of this Agreement to the contrary, for purposes of this Section 8.5(c), the Parties hereby agree that Chiron shall not be obligated to bear any portion of the costs or other amounts paid and required to be paid by Cubist to obtain and maintain such license if the intellectual property rights of such Third Party that are infringed or allegedly infringed by the use or practice of any Cubist Technology, or the research, development, manufacture, use, sale, offer for sale or importation of Licensed Products in the Territory, consists of Patents of such Third Party that had published or were generally available to the public as of the Effective Date (a “Knowable Patent”).

(d) Determination of Relative Financial Benefits. In connection with any determination of the relative financial benefits that could reasonably be expected to be derived by Chiron, Cubist and, if applicable, Third Party licensees of Cubist in connection with any

(e) Limitation of Obligation to Sublicense. Notwithstanding anything in this Agreement expressed or implied to the contrary, Cubist shall have no obligation to sublicense to Chiron any rights licensed by Cubist pursuant to Section 8.5(c) if Chiron has not agreed in writing to pay, and does not make payment when due, of the portion of the cost and expense incurred or to be incurred by Cubist in connection with seeking and maintaining such license that Chiron is required to pay pursuant to Section 8.5(c).

(f) Defense. The Party against which a Third Party Infringement Claim is brought shall defend against such claim at its sole expense and the other Party shall have the right, but not the obligation, to participate in any such suit, at its sole option and at its own expense. Such other Party shall reasonably cooperate with the Party conducting the defense of the claim, including if required to conduct such defense, furnishing a power of attorney.

(g) Settlement. Neither Party shall enter into any settlement of a claim brought under this Section 8.5 that materially adversely affects the other Party’s rights or interests without such other Party’s written consent, which consent shall not be unreasonably withheld or delayed.

(a) Third Party Patent Rights. If either Party desires to bring an opposition, action for declaratory judgment, nullity action, interference, reexamination or other attack upon the validity, title or enforceability of a Patent owned or Controlled by a Third Party that covers or may cover the manufacture, use, sale, offer for sale or importation of any Licensed Product, such Party shall so notify the other Party and the Parties shall promptly confer in good faith to determine whether to bring such action or the manner in which to settle such action. Cubist shall have the first right, but not the obligation, to bring at its own expense and in its sole control such action outside the Territory. If Cubist does not bring such action within ninety (90) days of notification thereof pursuant to this Section 8.6(a) (or earlier, if required by the nature of the proceeding), Chiron shall have the right, but not the obligation, to bring at Chiron’s expense and in its sole control, such action. Chiron shall have the first right, but not the obligation, to bring at its own expense and in its sole control such action in the Territory. If Chiron does not bring such action within ninety (90) days of notification thereof pursuant to this Section 8.6(a) (or earlier, if required by the nature of the proceeding), Cubist shall have the right, but not the obligation, to bring at Cubist’s expense and in its sole control, such action. The Party not bringing an action under this Section 8.6(a) shall be entitled to separate representation in such proceeding by counsel of its own choice and at its own expense, and shall cooperate reasonably with the Party bringing such action. Any awards or amounts received in bringing any such action shall be first allocated to reimburse the Parties’ reasonable expenses incurred in such action, and any remaining amounts shall be retained by the Party bringing such action.

(b) Parties’ Patent Rights. If a Cubist Patent, a Chiron patent or a Joint Patent becomes the subject of any proceeding commenced by a Third Party in connection with an opposition, reexamination request, action for declaratory judgment, nullity action, interference or other attack upon the validity, title or enforceability thereof, then the Party responsible for the prosecution of such Cubist Patent, such Chiron Patent or such Joint Patent pursuant to Section 8.2 hereof shall control such action at the sole cost or expense of the controlling Party unless the Parties otherwise agree in writing. The controlling Party will permit the non-controlling Party to participate in the proceeding to the extent permissible under law, and to be represented by its own counsel in such proceeding, at the non-controlling Party’s expense. If either Party decides that it does not wish to defend against such action, then the other Party shall have a backup right to assume defense of such Third Party action at its own expense. Any awards or amounts received in defending any such Third Party action shall be allocated between the Parties as provided in Section 8.4(e) as if the Party conducting such opposition were the Party that brought an action against an alleged infringer.

(c) Noncontravention. Nothing in this Section 8.6 shall be construed to relieve either Party of its obligations under Section 8.5 hereof.

(a) Generally. The licenses granted under Article 2, to the extent they include sublicenses of Third-Party technology licensed by Cubist as of the Effective Date, a complete list of which is set forth in Exhibit E, and including without limitation the Lilly License (“Effective Date Third Party Licenses”), shall be subject to the terms and conditions of such Effective Date Third Party Licenses. Cubist shall faithfully and timely perform and discharge its obligations under the Effective Date Third Party Licenses (including without limitation the payment of all royalties and other financial compensation due to such Third Parties thereunder in connection with the sale of Licensed Products) and shall not permit any action to be taken or event to occur, in each case, within Cubist’s reasonable control, which would give such Third Party the right to terminate such Effective Date Third Party License. Further, Cubist shall not amend any Effective Date Third Party License without Chiron’s consent, such consent not to be unreasonably withheld. Notwithstanding the provisions of the foregoing two sentences, Cubist shall not be liable to Chiron for breach of the obligations set forth in the foregoing two sentences unless such breach shall materially adversely affect Chiron’s ability to develop or Commercialize Licensed Products in accordance with the provisions of this Agreement. If Cubist is notified or otherwise becomes aware of its material breach of any such Effective Date Third Party License, it shall promptly notify Chiron in writing, reasonably detailing such breach. Cubist shall also notify Chiron of any material breach by such Third Parties of any of their obligations under the Effective Date Third Party Licenses. The Parties shall promptly confer in good faith regarding an appropriate manner for curing any such breach within the time allotted by such Effective Date Third Party License, or if the Third Party is in breach, monitoring the ability and adequacy of the Third Party’s efforts to cure such breach. If Cubist does not perform the agreed-upon remedy of such breach within the designated time, then Chiron may itself perform the agreed-upon remedy for such breach for the benefit of Cubist and any amounts that Chiron pays to cure such breach shall be either promptly reimbursed by Cubist or Chiron may withhold an equal amount from any payments due to Cubist under this Agreement. If a good faith dispute between a Third Party and Cubist arises about the interpretation of any provision within such Effective Date Third Party

(b) Lilly License. It is agreed and acknowledged that in the event of termination of the Lilly License, any sublicense granted by Cubist to Chiron under this Agreement of any rights granted by Lilly to Cubist under the Lilly License shall automatically be assigned by Cubist to Lilly in accordance with the provisions of Section 10.06 of the Lilly License.

(c) Decision to License Third Party Technology. In the event that either Party believes that certain Third Party intellectual property may be useful to the development, manufacture, use, sale, offer for sale or import of Licensed Products in the Territory and/or outside the Territory, then such Party shall request through the JCT that the Parties consider (i) whether the Parties should seek a license to such Third Party intellectual property to allow either or both Parties to use or practice such Third Party intellectual property in connection with the development, manufacture, use, sale, offer for sale or import of Licensed Products, (ii) how to allocate the costs of obtaining and maintaining such license between the Parties, (iii) how the Parties should proceed to seek such license, and (iv) whether, instead of seeking such license, the Parties can develop, manufacture, use, sell, offer for sale or import Licensed Product in a way that would eliminate or reduce the usefulness or desirability of licensing such Third Party intellectual property.

(d) Licensing of Third Party Technology. If the Parties reach a consensus that the Parties should seek a license to any Third Party intellectual property referred to in Section 8.7(c), then the Parties shall seek such license in a manner and on terms consistent with the determinations made by the Parties with respect to the matters set forth in clauses (i), (ii) and (iii) of Section 8.7(c). If the Parties are unable to reach a consensus that the Parties should seek such license and if the Parties are unable to reach a consensus that the Parties can develop, manufacture, use, sell, offer for sale or import Licensed Products in a way that would eliminate or reduce the usefulness and desirability of obtaining such license, then either Party shall be free to itself seek such license at its sole cost and expense. If Cubist is the Party that seeks such license and such license consists of or provides rights useful to the development, manufacture, use, sale, offer for sale or import of Licensed Products in the Territory, then, at Chiron’s request made at any time during the Term, Cubist shall sublicense such rights to Chiron for use in the Territory provided that Chiron agrees in writing to make payment, and makes payment when due, to Cubist of the portion of the costs paid and required to be paid by Cubist to obtain and maintain such license that are reasonably appropriate for Chiron to bear in light of the relative financial benefits that could reasonably be expected to be derived from such license by Chiron in the Territory, on the one hand, and by Cubist and, if applicable, Third Party licensees of Cubist, outside the Territory, on the other hand. If Chiron is the Party that seeks such license and such license consists of or provides rights useful to the development, manufacture, use, sale, offer for sale or import of Licensed Products outside the Territory, then, at Cubist’s request made at any time during the Term, Chiron shall sublicense such rights to Cubist outside the Territory provided that Cubist agrees in writing to make payment, and makes payment when due, to Chiron of the portion of the costs paid and required to be paid by Chiron to obtain and maintain such license that are reasonably appropriate for Cubist to bear in light of the relative financial benefits that could reasonably be expected to be derived from such license by Cubist and, if

(e) Limitation of Obligation to Sublicense. Notwithstanding anything in this Agreement expressed or implied to the contrary, the Party that obtains a license pursuant to Section 8.7(d) above shall have no obligation to make the licensed rights obtained pursuant to such license available to the other Party if such other Party is not bearing a reasonably appropriate portion of the cost and expense of seeking and maintaining such license in light of the relative financial benefits that could reasonably be expected to be derived from such license by Chiron in the Territory, on the one hand, and by Cubist and, if applicable, Third Party licensees of Cubist outside the Territory, on the other hand.

(f) Determination of Relative Financial Benefits. In connection with any determination of the relative financial benefits that could reasonably be expected to be derived by Chiron, Cubist and, if applicable, Third Party licensees of Cubist in connection with any license obtained by Cubist or Chiron pursuant to this Section 8.7, such relative financial benefits shall be determined by considering actual and projected net sales and actual or projected royalties from sales of the applicable Licensed Product by Chiron, Cubist and, if applicable, Third Party licensees of Cubist in the territory or territories that is or are covered by any such license.

(a) Trademark License. Subject to the provisions set forth in this Section 8.10, Cubist hereby grants Chiron an exclusive, royalty-free license under its entire right, title and interest in and to the Cubist Marks to use and display the Cubist Marks in connection with the Commercialization of Licensed Products within the Territory. Chiron shall not use Cubist’s trade names and/or marks in a way which would be confusing or otherwise adversely affect their value. Chiron agrees that it will not reproduce or use the Cubist Marks in any manner whatsoever other than as authorized by this Agreement, and that its uses of the Cubist Marks will comply with the current trademark guidelines that Cubist may provide from time to time. Chiron shall provide Cubist with copies of any materials containing any Cubist Marks prior to using or disseminating such materials, and shall reasonably consider all comments made by Cubist regarding the use of the Cubist Marks. Cubist will have the right to monitor Chiron’s use of the Cubist Marks and to request that Chiron correct any failure to comply with this Section 8.10 adversely affecting the strength or value of such trademark.

(b) Selection and Registration of Product Trademarks. Subject to the provisions set forth below in this Section 8.10, Chiron shall use in connection with the Commercialization of any Licensed Product in the Territory those trademarks used by Cubist in connection with the Commercialization of such Licensed Product outside the Territory. In the event that (i) any trademark or trademarks used by Cubist in connection with the Commercialization of any Licensed Product outside the Territory may not be registered for use in the Territory with such Licensed Product or (ii) Chiron believes that it would be a significant advantage for the Commercialization of any Licensed Product in the Territory to select and use a trademark or trademarks in connection therewith that is or are different from the trademark or trademarks being utilized by Cubist in connection with the Commercialization of such Licensed Product outside the Territory, then Chiron shall notify Cubist about the matter and shall submit to Cubist several other trademarks that Chiron desires to use, and believes can be used, with the Licensed Product in question in the Territory. Cubist and Chiron shall jointly consider, discuss and decide the matter. Chiron shall not use any trademark in connection with the Commercialization of any Licensed Product within the Territory that is different from the trademark or trademarks being utilized by Cubist in connection with the Commercialization of such Licensed Product outside the Territory without Cubist’s written consent. Any trademark used by Chiron in connection with the Commercialization of any Licensed Product in the Territory that is different than the trademark or trademarks utilized by Cubist in connection with the Commercialization of such Licensed Product outside the Territory and that has been selected and approved in accordance with the provisions of this Section 8.10(b) is hereinafter referred to as an “Approved New Trademark”.

Chiron hereby assigns to Cubist any and all right, title, interest, and goodwill that Chiron may have in any such Approved New Trademark (other than the right, if applicable, set forth below in this Section 8.10 to register and maintain such Approved New Trademark and Chiron’s license and right to use such Approved New Trademark pursuant to the provisions of Section 8.10(a) hereof) and hereby agrees to execute such further documents as Cubist shall reasonably request to further evidence and perfect such assignment. In the event that the laws of any applicable country within the Territory shall not permit Cubist to register any Cubist ▇▇▇▇, then Chiron shall be responsible for registering and maintaining such Cubist ▇▇▇▇ in such applicable country, notwithstanding the fact that Cubist shall own such Cubist ▇▇▇▇, and any use or goodwill arising from use of the ▇▇▇▇ shall inure to the benefit of Cubist.

(c) Infringement of Trademarks by Third Parties. Each Party shall notify the other Party in writing promptly upon learning of any actual, alleged or threatened infringement in the Territory or outside the Territory of any Cubist ▇▇▇▇ or of any unfair trade practices, trade dress imitation, passing off of counterfeit goods, or like offenses, in any case involving or affecting Licensed Products in the Territory or outside the Territory (hereinafter “TM Infringement”). In the case of any TM Infringement in the Territory, after any such written notice has been sent and received with respect to such TM Infringement, the Parties shall confer in good faith as to the reasonable response to such TM Infringement. In the absence of other

(d) Product Trademarks Infringe Third Party Rights. Each Party shall notify the other Party in writing promptly upon being notified that any Cubist ▇▇▇▇ or trade dress associated with the sale of License Products in the Territory or outside the Territory is alleged to infringe any Third Party trademark or other related intellectual property rights.

(c) No Conflict. It has not entered into any agreement with any Third Party that is in conflict with the rights granted to the other Party under this Agreement, and has not taken any action that would in any way prevent it from granting the rights granted to the other Party under this Agreement, or that would otherwise materially conflict with or adversely affect the rights granted to the other Party under this Agreement.

(f) Regulatory Filings. Exhibit G is an accurate and complete list of all INDs, NDAs and other Drug Approval Applications for Licensed Products filed by Cubist anywhere in the world as of the Effective Date.

(a) Notice. If either Party believes that the other is in material breach of this Agreement with respect to one or more Licensed Products or if Cubist believes that Chiron is in material breach of the Supply Agreement with respect to one or more Licensed Products, then the Party holding such belief (the “Non-breaching Party”) may deliver notice of such breach to the other Party (the “Notified Party”). A breach by Chiron of its diligence obligations under Section 5.1 or under Section 6.1 hereof and a breach by Cubist of its obligation under Section 4.1 hereof, except as specified otherwise, shall be deemed to be a material breach of this Agreement by Chiron or Cubist, as the case may be. The Notified Party shall have ninety (90) days to cure such breach, provided that, if cure cannot be reasonably effected within such ninety (90) day period, the Notified Party may elect to deliver to the Non-breaching Party within such ninety (90) day period a plan to cure such breach within a timeframe that is reasonably prompt in light of the circumstances then prevailing, and the Non-breaching Party shall have the right to approve or reject in writing such proposed plan in its absolute discretion. If the Non-breaching Party approves in writing such proposed plan, then the cure period will be extended in accordance with the terms of such plan and the Notified Party shall use Commercially Reasonable Efforts to carry out such plan and cure the breach in accordance with the provisions of such plan.

(b) Failure to Cure. If the Notified Party fails to cure such breach as provided for in Section 13.4(a), the Non-breaching Party may terminate this Agreement either in its entirety or with respect to one or more Licensed Products upon written notice to the Notified Party, provided that, the Non-breaching Party gives such written notice of termination within [*] after the Notified Party has failed to cure such breach as provided for in Section 13.4(a).

(c) Disputes. If a Party gives notice of termination under this Section 13.4 and the other Party disputes whether such termination is proper under this Section 13.4, then the issue of whether this Agreement may properly be terminated upon expiration of the notice period

(unless such breach is cured as provided in Section 13.4(a)) shall be resolved in accordance with Article 14 (Dispute Resolution). If as a result of such dispute resolution process it is determined that the notice of termination was proper, then such termination shall be deemed to have been effective ninety (90) days following the date of the notice of termination. If as a result of such dispute resolution process it is determined that the notice of termination was improper, then no termination shall have occurred and this Agreement shall remain in effect.

(d) Termination as to Certain Licensed Products. Notwithstanding the foregoing provisions of this Section 13.4, Cubist may exercise its right to terminate the Agreement pursuant to this Section 13.4 with respect to one or more particular Licensed Products as to which Chiron has breached its obligations under this Agreement or the Supply Agreement, rather than with respect to the entire Agreement, in which case the notice provided by Cubist pursuant to Section 13.4(a) shall specify that the Agreement is being terminated pursuant to this Section 13.4 only with respect to certain Licensed Products listed in such notice. If Cubist makes such an election under this Section 13.4(d), then subsections (a) through (c) shall be deemed to refer to termination of the Agreement only with respect to those Licensed Products set forth in the notice provided pursuant to Section 13.4(a).

(e) Right to Sell. Notwithstanding anything expressed or implied in this Agreement to the contrary, in the event that Cubist shall terminate this Agreement in accordance with the provisions of this Section 13.4, Chiron shall, notwithstanding any such termination, have the opportunity and right to sell, assign, sublicense or otherwise transfer this Agreement and the Chiron Interest to any Reasonable Buyer pursuant to, and in accordance with, the provisions of Section 15.6 of this Agreement, provided that any such sale, assignment, sublicense or other transfer is effected [] after the expiration of the cure period referred to in Section 13.4(a) or, in the event that there is a dispute between the Parties as to whether Cubist’s termination of this Agreement has been proper, [] after the resolution of such dispute pursuant to the provisions of Article 14 hereof. Any such Reasonable Buyer shall acquire the Chiron Interest free and clear of any breach by Chiron that led to the termination of this Agreement and such Reasonable Buyer shall following such acquisition have all of the rights and obligations that Chiron would have had under this Agreement as if Chiron had not breached this Agreement and Cubist had not terminated the Agreement. Any such sale, assignment, sublicense or other transfer of the Chiron Interest to a Reasonable Buyer pursuant to this Section 13.4(e) shall not relieve or release Chiron from any liability that Chiron may have to Cubist in connection with any breach that resulted in the exercise by Cubist of its right to terminate this Agreement. Until the expiration of the [] referred to above in this Section 13.4(e), Chiron shall continue to perform in accordance with the provisions of this Agreement and the Supply Agreement, and shall be liable for, any and all obligations that accrue during such [] under this Agreement and the Supply Agreement. In the event that Chiron is unable to consummate a sale, assignment, sublicense or other transfer of this Agreement and the Chiron Interest within such [*], then all of Chiron’s rights under this Section 13.4(e) shall terminate and be of no further force or effect whatsoever

(a) Assignment by Cubist. Cubist may sell, assign, sublicense or otherwise transfer this Agreement, the Supply Agreement, all (or any portion) of its rights under this Agreement or the Supply Agreement and/or all (or any portion) of its obligations under this Agreement or the Supply Agreement to a Third Party, without any requirement or condition that Chiron consent to any such sale, assignment, sublicense or other transfer, provided that:

(b) Assignment by Chiron. Notwithstanding any other provision in this Agreement to the contrary, Chiron may not sell, assign, sublicense or otherwise transfer this Agreement, the Supply Agreement or any of its rights or obligations under this Agreement or the Supply Agreement without the prior written consent of Cubist (which consent may be withheld or delayed by Cubist in its absolute discretion), except for any sale, assignment, sublicense or other transfer that is effected in strict compliance with the provisions set forth below in this Section 15.6(b) and Section 15.6(c) which shall not require or be conditioned upon any consent by Cubist to any such sale, assignment, sublicense or other transfer. At any time from and after [*], Chiron may sell, assign, sublicense or otherwise transfer this Agreement and the Supply Agreement and all (but not less than all) of its rights and obligations under this Agreement and the Supply Agreement (collectively, the “Chiron Interest”) to any Reasonable Buyer without having to obtain the consent of Cubist to any such sale, assignment, sublicense or other transfer; provided, however, that (i) prior to any such sale, assignment, sublicense or other transfer of the Chiron Interest, such Reasonable Buyer has expressly agreed in writing to assume the

performance of any and all obligations of Chiron under this Agreement and the Supply Agreement, and (ii) Chiron shall have given Cubist at least [] advance notice of any such sale, assignment, sublicense or other transfer; and, provided, further, that, if and to the extent applicable, all of the conditions set forth in Section 15.6(c) below are satisfied. Notwithstanding the foregoing provisions of this Section 15.6(b), in the event that Cubist enters into a definitive agreement with any Third Party granting to such Third Party any Commercialization rights with respect to any Licensed Product in the United States, then at any time on or prior to [] any such definitive agreement between Cubist and such Third Party, Chiron may sell, assign, sublicense or otherwise transfer the Chiron Interest to any Third Party without having to obtain the consent of Cubist; provided, however, that as a part of the consummation of such sale, assignment, sublicense or other transfer of the Chiron Interest, such Third Party has expressly agreed in writing to assume the performance of any and all obligations of Chiron under this Agreement and the Supply Agreement; and, provided, further, that, if and to the extent applicable, all of the conditions set forth in Section 15.6(c) below are satisfied.

(c) Restrictions on Payments. Notwithstanding any other provision in this Section 15.6 to the contrary, Chiron’s right to sell, assign, sublicense or otherwise transfer its rights to the Chiron Interest to a Reasonable Buyer or any other Third Party subject to, and in accordance with, Section 15.6(b) without obtaining the consent of Cubist shall also be subject to the requirements and conditions that (i) such sale, assignment, sublicense or other transfer results in the transfer by Chiron of all of its then prospective economic rights in and to the Chiron Interest to such Reasonable Buyer or other Third Party, and (ii) in the event that any such sale, assignment, sublicense or other transfer calls for royalty payments, earn-out payments, milestone-based or performance-based payments or other payments of any kind to be made over time by such Reasonable Buyer or other Third Party to Chiron, the agreement between Chiron and such Reasonable Buyer or other Third Party shall stipulate a maximum aggregate dollar amount of royalty payments, earn-out payments, milestone-based or performance-based payments and/or other payments that such Reasonable Buyer or other Third Party shall pay to Chiron in connection with such sale, assignment, sublicense or other transfer of the Chiron Interest and shall also stipulate that from and after the sixth anniversary of the closing of any such sale, assignment, sublicense or other transfer such Reasonable Buyer or other Third Party shall have no further obligation to make any payments of any kind or pay any kind of consideration to Chiron in connection with such sale, assignment, sublicense or other transfer of the Chiron Interest.

(d) Injunctive Relief. The Parties hereby acknowledge that Cubist would suffer irreparable damage and injury in the event of any sale, assignment, sublicense or other transfer by Chiron of the Chiron Interest to any Reasonable Buyer or other Third Party if any such sale, assignment, sublicense or other transfer would not be effected in compliance with the provisions of Section 15.6(b) and Section 15.6(c). Accordingly, it is the intent of the Parties that in the event that Chiron attempts or is attempting to sell, assign, sublicense or otherwise transfer the Chiron Interest without complying with all of the provisions of Section 15.6(b) and Section 15.6(c), Cubist may, in addition to any other remedies that Cubist may have at law, seek injunctive relief against Chiron (and/or any proposed transferee to the extent Cubist may be so entitled under applicable law) for the sole purpose of enforcing all of the provisions of Section 15.6(b) and Section 15.6(c). In the event that Cubist brings any such action for injunctive relief

to enforce the provisions of Section 15.6(b) and Section 15.6(c), Chiron hereby agrees to waive any defenses that Cubist has an adequate remedy at law and that Cubist will not suffer irreparable harm, and also any requirement that Cubist post any bond in connection with any such action for injunctive relief. For the avoidance of doubt, other than the defenses and the requirement specifically waived in the foregoing two sentences, nothing in this Section 15.6(d) shall be construed to be a waiver by Chiron of any of its remaining defenses at law or in equity.

(a) Chiron. Chiron shall not develop, promote, sell or offer for sale Licensed Products for use outside of the Territory. Chiron shall require its distributors who sell Licensed Products to make a covenant similar to that provided in this Section 2.7(a) with respect to Licensed Products.

In the event of, and following, any such replacement, Cubist shall use Commercially Reasonable Efforts to complete such Replacement Indication Study provided that Cubist may change, modify, abandon or discontinue such study to the same extent as provided in this Section 4.1 for the Key Development Studies.

Notwithstanding anything in this Section 4.1 to the contrary, prior to making any decision to abandon or discontinue any of the Key Development Studies, any Replacement Study or any Replacement Indication Study (each a “Required Study”), or to change or modify any Required Study so as to effectively abandon same, Cubist shall have first provided its reasons in support of such decision to Chiron via the JCT and the JCT shall have met to discuss the merits of such decision. Cubist shall bear all of the costs and expenses in connection with any and all development activities engaged in by Cubist and its Affiliates in connection with all Required Studies.

Cubist shall update the Cubist Development Plan annually and provide such updated Cubist Development Plan to Chiron prior to the JCT’s last scheduled meeting during the then current year. Chiron shall have the right to review and comment, via the JCT, on the Cubist Development Plan and any and all revisions and updates thereto, and Cubist shall, in good faith, consider all comments made by Chiron.

(b) Subject to the provisions of this Section 4.2(b), Cubist shall use Commercially Reasonable Efforts to carry out and perform during each calendar year the activities set forth in the Cubist Development Plan as may be in effect for such calendar year that are materially significant for obtaining Regulatory Approval. With the exception of the Required Studies (which Cubist may not change, modify, abandon or discontinue except in accordance with the provisions of Section 4.1 hereof), Cubist reserves the right at any time to change or modify the Cubist Development Plan or any of the preclinical studies or clinical trials described in the Cubist Development Plan, or to abandon any portion of the Cubist Development Plan or discontinue any such preclinical studies or clinical trials, in response to (i) changes in clinical or regulatory strategy, (ii) regulatory feedback, (iii) scientific feasibility, (iv) increases in the anticipated costs of clinical trials, (v) any significant adverse event or condition relating to the safety or efficacy of a Licensed Product, (vi) manufacturing feasibility, including, without limitation, changes in the anticipated costs of manufacturing, (vii) significant adverse changes in market conditions or in market potential of a drug candidate, or (viii) any other reason that Cubist determines in its reasonable discretion justifies such change, modification, abandonment or discontinuation; however, prior to making any decision to abandon any development effort (or change or modify any such effort so as to effectively abandon same), Cubist shall have first

provided its reasons in support of such decision to Chiron via the JCT and the JCT shall have met to discuss the merits of such decision.

(c) Except to the extent otherwise provided in Section 4.2(d) below, Cubist shall bear all of the costs and expenses in connection with any and all development activities engaged in by Cubist and its Affiliates pursuant to, and in accordance with, the provisions of this Section 4.2 and any Cubist Development Plan made hereunder.

(d) In the event that Cubist and Chiron consider it appropriate to consolidate their efforts in the Territory in the Cubist Development Plan and the Chiron Development Plan into common clinical studies, the Parties shall discuss at the JCT an appropriate sharing of resources, costs and expenses in connection with such studies. If the Parties cannot agree to a sharing of resources, costs and expenses, then neither Party shall be obligated to consolidate its respective clinical activities with those of the other Party. Except pursuant to any such agreement between Cubist and Chiron, Cubist shall have no obligation to undertake any clinical studies or to make material protocol changes that are not required by the FDA or any other Regulatory Authorities outside the Territory but are proposed to be undertaken for the sole purpose of complying with the requirements of any Regulatory Authority in the Territory.

Following such discussion, in the absence of consensus, Cubist shall have the right to require Chiron to modify or discontinue those development activities that Cubist reasonably and in good faith believes, based on the totality of the data, facts and knowledge presented to Chiron and the data, facts and knowledge presented by Chiron in response, are substantially likely to result in Global Harm. In the event that there is no person (including a successor-in-interest to Cubist) to carry out Cubist’s development obligations under Section 4.1, then (i) the provisions of this Section 4.3(e) shall not be applicable to the Licensed Product(s) as to which such development obligations are not being performed, and (ii) Chiron shall be free from its obligations to consult via the JCT under Sections 4.3(b) and 4.3(c) with respect to the Licensed Product(s) as to which such development obligations are not being performed. In the event that a successor-in-interest to Cubist shall be in material breach of such development obligations, then (i) the provisions of this Section 4.3(e) shall not be applicable to the Licensed Product(s) and the indication(s) as to which such development obligations are not being performed, and (ii) Chiron shall be free from its obligations to consult via the JCT under Sections 4.3(b) and 4.3(c) with respect to the Licensed Product(s) and the indications as to which such development obligations are not being performed.

(v) the proposed timetable for obtaining anticipated Regulatory Approval for the Launch Indication(s) in the countries referenced in the foregoing clauses (i) and (ii) of this Section 5.1(b), and the countries referenced in the foregoing clause (iii) of this Section 5.1(b), individually or in the aggregate, and a discussion of the factors that could result in an acceleration or a delay of such proposed timetable.

Chiron shall update the Regulatory Plan annually and provide such updated Regulatory Plan to Cubist prior to the JCT’s last scheduled meeting during the then current year. Such updated Regulatory Plan shall, at such later time as and when considered appropriate by Chiron in its sole discretion, cover, among other things, additional Licensed Products, additional indications and additional countries, considered individually or in the aggregate. Cubist shall have the right to review and comment, via the JCT, on the Regulatory Plan and any and all revisions and updates thereto, and Chiron shall, in good faith, consider all comments made by Cubist. For the avoidance of doubt, the foregoing provisions of this Section 5.1(b) shall not impose any obligation on Chiron to have any plan, strategy or any proposed activities, or to conduct any particular activities, with respect to any specific country within the Territory (it being understood that Chiron may have no such plan, strategy or any proposed activities with respect to any specific country in the Territory) but shall only impose an obligation on Chiron to set forth in the Regulatory Plan any such plan, strategy or proposed activities with respect to any specific country within the Territory to the extent that Chiron has any such plan, strategy or proposed activities. The provisions of the foregoing sentence shall not relieve Chiron from its obligations to use Commercially Reasonable Efforts under Section 5.1(c) below.

Subject to the provisions of this Section 5.1(b), Chiron shall use Commercially Reasonable Efforts to carry out and perform during each calendar year the plan, strategy and proposed activities set forth in the Regulatory Plan, as may be in effect for such calendar year, that are materially significant for obtaining Regulatory Approval in the Territory. Chiron reserves the right at any time to change or modify the Regulatory Plan in response to (i) changes in clinical strategy or regulatory strategy of either Chiron or Cubist, (ii) regulatory feedback, (iii) scientific feasibility, (iv) increases in anticipated costs of any Territory Specific Studies, (v) any significant adverse event or condition relating to the safety or efficacy of a Licensed Product, (vi) manufacturing feasibility, including, without limitation, changes in the anticipated costs of manufacturing and/or procuring Licensed Product, (v) significant adverse changes in market conditions or a market potential of a drug candidate, or (vi) any other reason that Chiron determines in its reasonable discretion justifies such change or modification; however, prior to making any decision to change or modify the Regulatory Plan (other than the annual updates), Chiron shall have first provided its reasons in support of such decision to Cubist via the JCT and the JCT shall have met to discuss the merits of such decision. The exercise by Chiron of any right that it may have under this Section 5.1(b) to change or modify all or any portion of the Regulatory Plan shall not relieve Chiron from its obligations to use Commercially Reasonable Efforts under Section 5.1(c) below or Section 6.1 hereof.

(x) conduct and complete any Territory Specific Study in accordance with the approved protocol, subject to (X) Chiron’s right under Section 4.3(a) to decline to perform any given Territory Specific Study for economic reasons, (Y) Cubist’s right under Section 4.3(e) to require Chiron to modify or discontinue a specific study for substantial likelihood of Global Harm, and (Z) completion of the steps described in Section 5.1(c)(ix), above.

Notwithstanding any provision of this Section 5.1(c) to the contrary, Chiron shall not be deemed to be in material breach of any of its obligations under this Section 5.1(c) to prepare and file applications for Regulatory Approval for each Launch Indication if and to the extent that Chiron cannot meet any of such obligations solely by virtue of the fact that one or more Regulatory Authorities do not permit Chiron to file such applications for Regulatory Approval for only a single indication. If a Regulatory Authority in the Territory informs Chiron that it may not file applications for Regulatory Approval for a single indication, then the Parties shall convene a meeting of the JCT to discuss alternative strategies that could be pursued by the

* CONFIDENTIAL TREATMENT REQUESTED: MATERIAL HAS BEEN OMITTED AND FILED WITH THE COMMISSION

Parties. In the event that Chiron is not permitted to file applications for Regulatory Approval in any country within the Territory for a single indication, then the Parties agree that as soon thereafter as Chiron is permitted to file for Regulatory Approval in such country (whether because such filing will be for more than a single indication or because the regulatory environment in such country has changed so as to permit a filing for Regulatory Approval for a single indication), then Chiron shall at that time again be obligated to comply with the requirements, if any, imposed by this Section 5.1(c) with respect to preparing and making filings for Regulatory Approval in such country, and, for purposes of applying the timelines in this Section 5.1(c) at that time, the date on which Chiron is first permitted to make such filing in such country shall be deemed to be the end of the [*] period after Cubist has given to Chiron all of the information necessary to make such filing.

To the extent that Chiron needs to submit and make available any Manufacturing Information in connection with obtaining Regulatory Approval in the Territory, the Parties agree that, to the fullest extent permissible under applicable law, rules and regulations, such Manufacturing Information shall be made available to the applicable Regulatory Authorities in the Territory via a Drug Master File appropriately formatted for the country in which such DMF is filed and [*] (i.e. upon Chiron’s [*] under the Supply Agreement to manufacture or have manufactured Licensed Products). Drug Master Files will be maintained and kept up to date by Cubist or the Cubist Suppliers. Chiron will be notified of changes proposed to the DMF [*] in accordance with change control procedures set forth in Section 3.2 of the Supply Agreement. Chiron shall be responsible for notifying the Regulatory Authorities in the Territory, as required by applicable laws, of the updating of the DMF by Cubist or the Cubist Suppliers.

Notwithstanding the foregoing, the applicable Regulatory Authorities in the Territory shall have full access to all of the Manufacturing Information in such DMF [*], to the extent considered necessary by such applicable Regulatory Authorities to consider and act upon any applications for Regulatory Approvals in the Territory that are submitted by Chiron, and [*] to allow such Regulatory Authorities to refer to all of the Manufacturing Information in such DMF to the extent necessary to assess applications for Regulatory Approvals of Licensed Products in the Territory and to obtain such Regulatory Approvals.

If and to the extent that Chiron needs to submit and make available any Manufacturing Information in connection with any submission by Chiron of any application for Regulatory Approval of Licensed Product within the Territory and the applicable regulatory requirements do not permit the submission of such Manufacturing Information via a DMF, then the Parties agree that such Manufacturing Information shall be made available to Chiron for the sole purpose of filing applications for Regulatory Approvals of Licensed Products in the Territory and obtaining such Regulatory Approvals, and that Chiron shall not be entitled to use such Manufacturing Information for any other purpose whatsoever other than to manufacture or have manufactured Licensed Products and conduct quality assurance testing and release of Finished Products, but only if, when and to the extent that Chiron is expressly authorized under the Supply Agreement to use such Information for such manufacturing purposes.

Cubist shall consult with Chiron prior to any such face-to-face meeting or scheduled conference calls at which Chiron is present and participating to develop a strategy for the meeting.

(a) The Parties shall exchange their internal standard operating procedures (“SOPs”) as to product recalls and the treatment of product complaints and inquiries as to safety, quality or efficacy reasonably in advance of the date of Commercial Launch of any Licensed Product in the Territory. If either Party becomes aware of information about any Licensed Product indicating that it may not conform to the specifications for Licensed Product then in effect pursuant to the Supply Agreement, or that there are potential adulteration, misbranding and/or other issues regarding safety or effectiveness, it shall promptly so notify the other Party. The JCT shall meet to discuss such circumstances and to consider appropriate courses of action, which courses of action with respect to each recall shall be consistent with the internal SOP of the Party having the right to control such recall pursuant to this Section 5.7. Except to the extent otherwise provided in Section 5.7(b) below, Chiron shall control, at its sole expense, all recalls of Licensed Product within the Territory. Cubist shall control, at its sole expense, all recalls of Licensed Product outside the Territory. Chiron shall maintain complete and accurate records of any recall for such periods as may be required by legal requirements, but in any event for no less than three (3) years.

(b) In the event that any recall of Licensed Product in the Territory is required or necessary by virtue of such Licensed Product being Defective Manufactured Product, then both Parties shall work together to devise a reasonable and appropriate plan to implement such recall, it being understood that the objective of such plan shall be to effect such recall as quickly and as cost-effectively as reasonably possible under the circumstances. After the Parties shall have reached agreement on the terms of such plan (or, in the event that the Parties cannot reach agreement as to the terms of such plan, Chiron shall have the right, acting reasonably and in good faith, to adopt another plan), Chiron shall implement such recall in a manner consistent with the terms of such plan. Cubist shall cooperate with Chiron in any way that Chiron reasonably requests in order to support the implementation of such recall. Subject to the limitation of liability set forth in Section 10.6(a), Cubist shall reimburse Chiron for all Recall Expenses (as defined below) provided that [*]. For the avoidance of doubt, the limitation set forth above in this Section 5.7(b) (and in Section 6.6(b) of the Supply Agreement) on Cubist’s responsibility for Recall Expenses shall not apply to limit Chiron’s remedies and Cubist’s obligations or liabilities with respect to matters other than Recall Expenses, including, without limitation, (i) Cubist’s obligation to indemnify Chiron pursuant to Sections 10.1 and 10.3 of this Agreement with respect to costs and expenses other than Recall Expenses, and (ii) Chiron’s remedies under Sections 8.1, 9.1(d) and 11.6 of the Supply Agreement. “Recall Expenses” shall mean the costs and expenses incurred by Chiron in connection with a recall of Licensed Product that is implemented in accordance with this Section 5.7(b) (and/or Section 6.6(b) of the Supply Agreement), including, without limitation, the costs and expenses associated with notification and destruction and/or return of such recalled Licensed Product.

Effective upon the occurrence of the Marketing Plan Trigger Event, Chiron shall update annually and provide such updated Marketing Plan to Cubist prior to the JCT’s last scheduled meeting during the then current year. Such updated Marketing Plan shall, at such later time as Chiron shall determine in its sole discretion, cover, among other things, additional Licensed Products, additional indications and additional countries for which Regulatory Approval has been obtained, considered individually or in the aggregate. Cubist shall have the right to review and comment, via the JCT, on the Marketing Plan and any and all revisions and updates thereto, and Chiron shall, in good faith, consider all comments made by Cubist. For the avoidance of doubt, the foregoing provisions of this Section 6.1(a) shall not impose any obligation on Chiron to have any plan, strategy or any proposed activities, or to conduct any particular activities, with respect to any specific country within the Territory (it being understood that Chiron may have no such plan, strategy or any proposed activities with respect to any specific country in the Territory) but shall only impose an obligation on Chiron to set forth in the Marketing Plan any such plan, strategy or proposed activities with respect to any specific country within the Territory to the extent that Chiron has any such plan, strategy or proposed activities. The provisions of the foregoing sentence shall not relieve Chiron from its obligations to use Commercially Reasonable Efforts under Section 6.1(b) below.

Effective from and after the Marketing Plan Trigger Event, and subject to the provisions of this Section 6.1(a), Chiron shall use Commercially Reasonable Efforts to carry out and perform during each calendar year the plan, strategy and proposed activities set forth in the Marketing Plan, as may be in effect for such calendar year. Chiron reserves the right at any time to change or modify the Marketing Plan in response to (i) changes in clinical strategy or regulatory strategy of either Chiron or Cubist, (ii) regulatory feedback, (iii) scientific feasibility, (iv) increases in anticipated costs of any Territory Specific Studies, (v) any significant adverse event or condition relating to the safety or efficacy of a Licensed Product, (vi) manufacturing feasibility, including, without limitation, changes in the anticipated costs of manufacturing and/or procuring Licensed Product, (v) significant adverse changes in market conditions or a market potential of a drug candidate, or (vi) any other reason that Chiron determines in its reasonable discretion justifies such change or modification; however, prior to making any decision to change or modify the Marketing Plan (other than annual updates), Chiron shall have first provided its reasons in support of such decision to Cubist via the JCT and the JCT shall have met to discuss the merits of such decision. The exercise by Chiron of any right that it may have under this Section 6.1(a) to change or modify all or any portion of the Marketing Plan shall not relieve Chiron from its obligations to use Commercially Reasonable Efforts under Section 6.1(b) below.

(i) effect the Commercial Launch of Licensed Product for the Launch Indication(s) within [*] after obtaining Regulatory Approval and acceptable Price Approval therefor; and

(ii) market, sell and distribute Licensed Products for the Launch Indication(s), upon receipt of Regulatory Approval and acceptable Price Approval.

In addition and without limiting the foregoing, during the period commencing [*] before the date of first Commercial Launch of Licensed Product in each of the Major Market Countries, and continuing through the [*] after such first Commercial Launch, Chiron shall:

(1) budget and spend on marketing, advertising and promotion activities with respect to Licensed Product (exclusive of fully loaded direct and indirect costs attributable to salespersons): (A) in each Major Market Country an amount equal to the greater of: (I) [*], or (II) [*] of the forecasted Net Sales of such Licensed Product in such Major Market Country; or (B) in all of the Major Market Countries collectively, an aggregate amount equal to the greater of: (III) [*] the amount in the foregoing clause (I) during the period commencing [*] before the date of first Commercial Launch of Licensed Product in the first such country and continuing through the [*] after such first Commercial Launch in the last such country, or (IV) [*] the amount in the foregoing clause (II) during the period commencing [*] before the date of first Commercial Launch of Licensed Product in the first such country and continuing through the [*] after such first Commercial Launch in the last such country; and

(2) employ or engage not less than [*] salespersons to sell Licensed Products in each Major Market Country or not less than [*] salespersons in the aggregate in all of the Major Market Countries.

For purposes of the foregoing provisions of this Section 6.1(b), the availability of supply of Licensed Products shall be considered in determining whether Chiron has used Commercially Reasonable Efforts to meet its diligence obligations. Further, any delay by Chiron in effecting Commercial Launch in any Major Market Country until Regulatory Approval in such country has been obtained for a second indication (to the extent that a single indication does not allow Chiron to obtain acceptable Price Approval in such country) shall be deemed not to be a material breach by Chiron of any of its obligations under this Agreement.

For purposes of this Section 7.3, the first Royalty Year with respect to all Licensed Products shall commence on the date of Commercial Launch by Chiron or any of its Affiliates in any country within the Territory and end on December 31 of the year in which the Commercial Launch occurred. Each succeeding Royalty Year shall commence on January 1 of the ensuing

year and end on December 31 of such year. Accordingly, the determination of the Royalty Year for the purpose of determining the Royalty Rate which applies shall not be either on a Licensed Product-by-Licensed Product basis or on a country-by-country basis.

The determination of the Royalty Rate pursuant to the table in this Section 7.3(a) (i.e. whether the Royalty Rate in left hand column or the right hand column in the table above applies) shall also not be made on a Licensed Product-by-Licensed Product basis or on a country-by-country basis, but, instead, shall be made based on the aggregate amount of annual Net Sales for all Licensed Products in all countries in the Territory.

The determination of the amount of royalties due Cubist pursuant to this Section 7.3(a) shall be made on a Licensed Product-by-Licensed Product basis and on a country-by-country basis by multiplying the Royalty Rate that is applicable for any particular Royalty Year, as determined in accordance with the foregoing provisions of this Section 7.3(a), by the Net Sales arising from sales in each country within the Territory of units of each Licensed Product by Chiron or its Affiliates during each calendar quarter of the applicable Royalty Year.

in this Section 7.3(c) and Sections 7.3(d), 7.3(e) and 7.3(f), the obligation of Chiron and its Affiliates to pay royalties to Cubist under this Section 7.3 with respect to sales of such Licensed Product in such country shall terminate and be of no further force or effect.

(i) If within such [*] period Cubist sends written notice to Chiron stating that Cubist agrees with Chiron’s position on the issue, then the provisions of Section 7.3(c) shall apply to sales of such Licensed Product by Chiron or its Affiliates in such country and Chiron shall be entitled to cease paying royalties under this Section 7.3 in connection with such sales.

(ii) If Cubist does not send such written notice to Chiron within the [*] period in clause (i) above, but within [*] after the end of such [*], Cubist commences an action against the allegedly infringing Third Parties to enforce the Valid Claims and prevent sales of Unlicensed Products in such country, then Chiron shall continue making payment of royalties in connection with sales of the affected Licensed Product by Chiron or its Affiliates in such country in the manner set forth in Section 7.3(e).

(iii) If Cubist does not send such written notice to Chiron within the [*] period in clause (i) above and if Cubist does not commence such action within the [*] period in clause (ii) above, then the provisions of Section 7.3(c) shall be deemed to apply to sales of such Licensed Product by Chiron or its Affiliates in such country and Chiron shall be entitled to cease paying royalties under this Section 7.3 in connection with such sales.

If Chiron becomes entitled to cease paying royalties under Section 7.3(c) (i.e. pursuant to clause (i) or (iii) of this Section 7.3(d)), then, within [*] after Chiron so becomes entitled to cease paying royalties, Cubist shall make payment to Chiron of all unearned royalties previously paid by Chiron to Cubist as of the earliest month when sales of Unlicensed Product exceeded the [*] market share threshold, together with interest thereon at the rate specified for late payments pursuant to Section 7.10 hereof.

Any such arbitration shall be conducted in New York, New York by three (3) arbitrators. Each Party shall select one (1) arbitrator and such arbitrators shall jointly appoint the third arbitrator who shall act as the chairman. If either Party fails to appoint an arbitrator within thirty (30) days of a request by the other Party, or if the arbitrators selected by the parties cannot agree on a chairman within thirty (30) days after they have been selected, then either Party may request the ICC to appoint such co-arbitrator (for the non-responsive Party) or the chairman. Such appointment shall be binding on the Parties. Each Party irrevocably and unconditionally (i) consents to the jurisdiction of any such proceeding and waives any objection that it may have to personal jurisdiction or the laying of venue of any such proceeding; and (ii) knowingly and voluntarily waives its rights to have disputes tried and adjudicated by a judge and jury except as otherwise expressly provided herein. The Parties hereby agree to exercise their respective rights under the ICC Rules to cause any arbitration proceeding under this Section 14.2(a) to be finalized and a decision rendered by the arbitrators as soon as reasonably practicable but in no event more than six (6) months after the commencement of such arbitration proceeding. Without limiting the provisions of the preceding sentence, the Parties will cooperate with each other in causing the arbitration to be held in as efficient and expeditious a manner as practicable. Unless the Parties agree otherwise, they shall be limited in their discovery to directly relevant documents. Responses or objections to a document request shall be served twenty (20) days after receipt of the request. The arbitrators shall resolve any discovery disputes. Nothing herein shall prevent the Parties from settling any dispute by mutual agreement at any time.

(c) The arbitrator(s) shall not have the authority to award any injunctive relief or to award exemplary or punitive damages, and the Parties expressly waive any right to such damages. The arbitrator(s) shall have the authority to award actual money damages (including interest on unpaid amounts from the date due). The costs and expenses of the arbitration, but not the costs and expenses of the Parties, shall be shared equally by the Parties, provided that the non-prevailing Party in any arbitration shall pay the other Party’s costs and expenses (including travel expenses) and reimburse such Party for its portion of the arbitration costs. In the event that neither Party wins totally, reimbursement shall be made proportionally in accordance with the ICC Rules. Any award rendered by the arbitrator(s) shall be final and binding upon the Parties. Judgment upon the award may be entered in any court of competent jurisdiction. If a Party fails to proceed with arbitration, unsuccessfully challenges the arbitration award, or fails to comply with the arbitration award, the other Party is entitled to costs, including reasonable attorneys’ fees, for having to compel arbitration or defend or enforce the award.
