Cubist shall promptly disclose to ArQule the array plate number and well number of any Active Compounds. ArQule will promptly determine whether the Active Compounds are Available Compounds and notify Cubist of such determination. If an Active Compound is not an Available Compound, Cubist shall have no rights with respect to that Active Compound. For Available Active Compounds, ArQule shall disclose to Cubist the chemical composition and structure of those Active Compounds, and Cubist shall disclose to ArQule the identity of the Target, level of activity, and a description of the primary assays used to detect the activity. All such information disclosed by ArQule and Cubist shall be deemed Confidential Information and, as such, is subject to the restrictions set forth in Article 6. (c) Confirmation of Activity. For a period of [ ]* after the date upon which ArQule and Cubist exchange information about an Active Compound pursuant to Section 3.3.(b) (the "Reservation Period"), ArQule will reserve that Active Compound to the Collaboration. During the Reservation Period, ArQule will provide Cubist with reasonable additional quantities of that Active Compound and Cubist will perform secondary screens to confirm the activity of that Active Compound. The Research Committee will coordinate these confirmatory screening efforts. * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 13 <PAGE> (d) Designation of Collaboration Compounds. At any time during the Reservation Period, Cubist may request that the Research Committee designate the relevant Active Compound as a Collaboration Compound under this Agreement. After receiving this request, the Research Committee will confirm that the compound exhibits the requisite functional activity to qualify as an Active Compound, whereupon the Research Committee shall designate the relevant Active Compound as a Collaboration Compound under this Agreement. If the Research Committee fails to designate an ArQule Compound as a Collaboration Compound, then (i) Cubist shall have no rights with respect to that ArQule Compound and (ii) ArQule shall have the right to license or otherwise commit such ArQule Compound to a third party for any biological target and to include such ArQule Compound in an ArQule internal discovery program for an unrelated biological target, subject in both cases to the restrictions on Confidential Information set forth in Article 6. If the Research Committee does designate an ArQule Compound as a Collaboration Compound, then ArQule shall (i) internally designate the Collaboration Compound as committed to Cubist under this Agreement, (ii) remove the Collaboration Compound from future shipments of its Mapping Arrays, and (iii) undertake no internal program on the Target for which that Collaboration Compound exhibits activity. (e) Termination of Mapping Array Program. The Mapping Array Program described in this Section 3.3. will commence on the Effective Date and will continue during the term of this Agreement; provided that either party may terminate the Mapping Array Program before the expiration or termination of this Agreement with written notice to the other party which is received at least sixty (60) days prior to any anniversary of the Effective Date. In the event of early termination, Cubist shall immediately cease primary screens of the Mapping Array compounds but may (i) continue performing confirmatory screens of previously identified Active Compounds and (ii) request that the Research Committee designate any Active Compounds as Collaboration Compounds. all in accordance with the terms of this Agreement. 3.4. Conduct of Lead Optimization and Preclinical Development Activities. (a) Approval and Initiation of Project. At any time after an Active Compound is identified, but no later than sixty (60) days after the relevant Active Compound becomes a Collaboration Compound, the Research Committee may approve a proposal for the Lead Optimization and Preclinical Development of one or more Active Compounds for a Target. The Research Committee shall forward such proposals to the Steering Committee for approval. Once the Steering Committee approves a proposal, the proposed 14 <PAGE> research and development project shall automatically be designated a Collaboration Project under this Agreement. A Collaboration Project may be initiated by the parties at any time after the relevant Active Compounds have been designated as Collaboration Compounds by the Research Committee pursuant to Subsection 3.3.(d). If the Research Committee or Steering Committee fails to approve a proposed Lead Optimization or Preclinical Development project for one or more Collaboration Compounds for a Target because of withdrawal of a party or deadlock of the Steering Committee, the Collaboration Compound will be subject to compulsory commercialization pursuant to Subsection 3.4.(h). If the Research Committee or Steering Committee fails to approve a proposed Lead Optimization or Preclinical Development project for one or more Collaboration Compounds for a Target because of lack of business or scientific merit, the reversion provisions set forth in Subsection 3.4.(i) shall automatically take effect unless otherwise agreed by the parties. (b) Preparation and Approval of Research Plan and Preclinical Development Plan. Promptly following initiation of a Collaboration Project, the Research Committee shall prepare and submit to the Steering Committee (i) a proposed Research Plan for Lead Optimization of the relevant Collaboration Compounds to identify Preclinical Candidates and (ii) a preliminary Preclinical Development Plan for the Preclinical Development of any Preclinical Candidates that may be so identified. Unless otherwise decided by the Research Committee, the Research Plan shall provide that all Collaboration Compounds will be submitted to a Directed Array Program for Lead Optimization. The Steering Committee must approve the proposed Research Plan and the preliminary Preclinical Development Plan before the parties commence performance of the Collaboration Project. Before the parties commence any Preclinical Development activities, the Steering Committee must approve a final Preclinical Development Plan that is prepared and submitted by the Research Committee. The Research Committee will also prepare and submit to the Steering Committee any proposed modifications to previously approved Research Plans and Preclinical Development Plans. No such modifications will take effect until approved by the Steering Committee. (c) Responsibilities for Project. The parties intend that, in any Collaboration Project, ArQule will have general responsibility for tasks involving chemistry and Cubist will have general responsibility for tasks involving biology. However, the Research Committee will determine the actual tasks of each party for each Collaboration Project in accordance with an approved Research Plan or Preclinical Development Plan. If the Research Committee cannot agree upon the allocation of any task for a Collaboration Project, the matter shall be decided by the Steering Committee. If the 15 <PAGE> Steering Committee cannot resolve the matter within sixty (60) days after the Research Committee deadlocked, the tasks at issue will be performed by the party that has general responsibility for that task, as described Exhibit A. (d) Reports and Records. Each party agrees to promptly and regularly communicate to the other party all research results from a Collaboration Project, including quarterly reports to the Research Committee detailing all tests conducted and results obtained by such party in connection with a Collaboration Project. Each party shall prepare and maintain adequate records, including bound laboratory notebooks maintained in accordance with standard scientific procedures, containing all appropriate data reflecting all research results from a Collaboration Project. In addition, each party shall retain under appropriate conditions any necessary or desirable samples of Research Materials that are developed or used in a Collaboration Project. (e) Designation of Additional Collaboration Compounds. In the course of a Collaboration Project, Cubist is likely to detect additional Active Compounds for the relevant Target as it screens Directed Arrays derived from the Collaboration Compounds. After the Research Committee confirms that these ArQule Compounds exhibit the requisite functional activity to qualify as Active Compounds and ArQule confirms that the Active Compounds are Available Compounds, the Research Committee will designate such Active Compounds as additional Collaboration Compounds under this Agreement. (f) Designation of Preclinical Candidates. The Research Committee shall monitor Lead Optimization activities in each Collaboration Project. At the discretion of the Research Committee, but prior to commencement of any Preclinical Development activities for a Collaboration Project, the Research Committee shall designate one or more Collaboration Compounds as Preclinical Candidates for that Collaboration Project. Thereafter, the Research Committee shall have discretion to designate additional Collaboration Compounds as Preclinical Candidates and to eliminate Collaboration Compounds as Preclinical. Candidates for that Collaboration Project as circumstances warrant. The parties shall designate a Preclinical Candidate before commencing Preclinical. Development activities with a Collaboration Compound in a Collaboration Project. (g) Cross-Licenses for Lead Optimization and Preclinical Development. The following license grants shall have effect only with respect to activities undertaken in connection with and during the term of a Collaboration Project and as approved by the Research Committee: 16 <PAGE> (i) ArQule hereby grants Cubist a worldwide, [ ]*, exclusive (except as to ArQule) license under the ArQule Patent Rights and other rights in ArQule Technology to perform Lead Optimization and Preclinical Development in the Field with any Collaboration Compound. (ii) Cubist hereby grants ArQule a worldwide, [ ]*, exclusive (except as to Cubist) license under the Cubist Patent Rights and other rights in Cubist Technology to perform Lead Optimization and Preclinical Development in the Field with any Collaboration Compound. Each party acknowledges and agrees that these cross-licenses, while effective for a Collaboration Compound, preclude any further license grants in the Field by either party for that Collaboration Compound. Neither party shall have the right to sublicense the license grants set forth in this Section. During the term of a Collaboration Project, neither party shall grant any right or license under the applicable Joint Patent Rights or other rights in Joint Technology to any third party without the prior written consent of the other party. (h) Withdrawal or Deadlock. In the event that a party desires to withdraw from a proposed or ongoing project for Lead Optimization or Preclinical Development for one or more Collaboration Compounds for a Target, or if the Steering Committee deadlocks regarding (i) approval of a proposed Lead Optimization and Preclinical Development project pursuant to Subsection 3.4.(a) or (ii) an issue that arises in an ongoing Collaboration Project, the parties will immediately cease work on the Collaboration Project and attempt to outlicense the work product of that Collaboration Project. At the request of either party, the parties will select a mutually acceptable technology broker who shall have authority to license such work product on their behalf. If the parties cannot select a mutually acceptable technology broker within thirty (30) days, each party will select a third party representative and these representatives will select the technology broker. If neither party desires to use a technology broker, the parties will jointly market such work product and jointly negotiate and execute any resulting license agreement. [ ]* will pay [ ]* of any costs and expenses (including without limitation brokers fees, attorneys fees, and travel expenses) incurred in connection with any outlicensing activities under this Subsection, and [ ]* will receive [ ]* of any income resulting from such license. As an alternative to forced commercialization of such work * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 17 <PAGE> product, either party may make a buy-out offer to the other party at any time, but the other party may reject any buy-out offer and seek to outlicense the work product, in its sole discretion. (i) Lack of Merit. A Collaboration Project shall terminate immediately in the event of a decision by the Research Committee or Steering Committee to terminate the Collaboration Project for lack of scientific or business merit. In such event, the reversion provisions set forth below shall automatically take effect unless otherwise agreed by the parties: (i) Cubist shall have no further rights under the ArQule Patent Rights or ArQule Technology with respect to such Collaboration Compounds; (ii) ArQule shall have no further rights under the Cubist Patent Rights or Cubist Technology with respect to such Collaboration Compounds; (iii) Cubist shall grant ArQule an exclusive, worldwide, [ ]* license (with the right to sublicense) under any Joint Patent Rights and other rights in Joint Technology to the extent applicable to the composition of such Collaboration Compounds, provided that ArQule shall not assert such rights against any Cubist Collaborator that discovers such Collaboration Compounds independent of any information (whether or not published) derived from either party or arising from the Collaboration; (iv) ArQule retains the right to assert all ArQule Patent Rights and other rights in ArQule Technology against Cubist and any Cubist Collaborator; (v) ArQule shall grant Cubist an exclusive, worldwide, [ ]* license (with the right to sublicense) under any Joint Patent Rights and other rights in Joint Technology to the extent applicable to the use of such Collaboration Compounds with the identified Targets, provided that Cubist shall not assert such rights against any ArQule Collaborator that discovered such use independent of any information (whether or not published) derived from either party or arising from the Collaboration; and * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 18 <PAGE> (vi) Cubist retains the right to assert all Cubist Patent Rights and other rights in Cubist Technology against ArQule and any ArQule Collaborator. Each party shall remain subject to the restrictions on Confidential Information set forth in Article 6. Cubist acknowledges that ArQule shall have the right to [ ]* ArQule acknowledges that Cubist shall have the right (i) to screen and develop compounds other than those Collaboration Compounds, and (ii) to screen and develop those Collaboration Compounds if such compounds are independently discovered by a third party who, on its own initiative, offered those compounds to Cubist for use with the identified Target. 3.5. Clinical Development of Collaboration Compounds. (a) Designation of Clinical Candidate. After approval of an IND for a Preclinical Candidate, the Research Committee may designate that Preclinical Candidate as a Clinical Candidate for the purposes of this Section 3.5. Neither party will commence Clinical Development of any Collaboration Compound or Derivative before such compound has been designated as a Clinical Candidate in accordance with this Section. The Steering Committee will develop a Commercialization Plan for each Clinical Candidate. (b) Co-Development Right. Without further action, each party shall have the co-exclusive right to conduct the Clinical Development, commercial license, manufacture, distribution, marketing, and sale of any Clinical Candidate. (c) Authority. The parties shall have joint responsibility for and control over all activities for the Clinical Development and commercialization of the relevant Clinical Candidate, in accordance with the Clinical Development Plan and Commercialization Plan. The Steering Committee shall decide whether to proceed with each stage of Clinical Development and shall have oversight, management, and approval authority for commercialization decisions, activities, and agreements. The Research Committee shall have oversight and management authority for Clinical Development activities. Unless otherwise agreed by the parties, any grant of commercial rights * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 19 <PAGE> in a Clinical Candidate shall require the signatures of both parties to become effective. (d) Development Licenses. The following license grants shall have effect only with respect to activities approved by the Steering Committee and undertaken in connection with the Clinical Development of the relevant Clinical Candidate: (i) ArQule hereby grants Cubist a worldwide, [ ]*, exclusive (except as to ArQule) license under the ArQule Patent Rights, Joint Patent Rights, and other rights in ArQule Technology and Joint Technology to perform Clinical Development of the Clinical Candidate. (ii) Cubist hereby grants ArQule a worldwide, [ ]*, exclusive (except as to Cubist) license under the Cubist Patent Rights, Joint Patent Rights, and other rights in Cubist Technology and Joint Technology to perform Clinical Development of the Clinical Candidate. Each party acknowledges and agrees that these cross-licenses, while effective for Clinical Candidate, preclude any further license grants in the Field by either party for the Clinical Development of that Clinical Candidate. Neither party shall have the right to sublicense the license grants set forth in this Subsection without the approval of the Research Committee or Steering Committee, as appropriate. (e) Withdrawal and Deadlock. Each party shall have the right to decline to participate in, or to withdraw from, Clinical Development activities for a particular Clinical Candidate at any time upon sixty (60) days prior written notice to the other party. In such event, the relevant Collaboration Project shall terminate upon the conclusion of the sixty-day notice period. In the event that the Steering Committee reaches deadlock on an issue that arises in connection with Clinical Development or commercialization activities for a particular Clinical Candidate, the Collaboration Project shall immediately terminate. If a Collaboration Project terminates due to withdrawal or deadlock under this Section, the parties will immediately cease work on the Collaboration Project and attempt to outlicense the work product of that Collaboration Project. At the request of either party, the parties will select a mutually acceptable technology broker who shall have authority to license such work product on their behalf. If the parties cannot select a mutually acceptable technology broker within thirty * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 20 <PAGE> (30) days, each party will select a third party representative and these representatives will select the technology broker. If neither party desires to use a technology broker, the parties will jointly market such work product and jointly negotiate and execute any resulting license agreement. [ ]* will pay [ ]* of any direct costs and expenses (including without limitation brokers fees, attorneys fees, and travel expenses) incurred in connection with any outlicensing activities under this Subsection, and [ ]* will receive [ ]* of all proceeds resulting from such license. As an alternative to forced commercialization of such work product, either party may make a buy-out offer to the other party at any time, but the other party may reject any buy-out offer and seek to outlicense the work product, in its sole discretion. (f) Lack of Merit. In the event of a decision by the Research Committee or Steering Committee to terminate Clinical Development or commercialization activities for a Clinical Candidate for lack of clinical or business merit, the development licenses set forth in Subsection 3.5.(d) shall automatically and immediately terminate and the reversion provisions set forth below shall automatically take effect unless otherwise agreed by the parties: (i) Cubist shall have no further rights under the ArQule Patent Rights or ArQule Technology with respect to such Clinical Candidate and all other Collaboration Compounds within that Collaboration Project; (ii) ArQule shall have no further rights under the Cubist Patent Rights or Cubist Technology with respect to such Clinical Candidate and all other Collaboration Compounds within that Collaboration Project; (iii) Cubist shall grant ArQule an exclusive, worldwide, [ ]* license (with the right to sublicense) under any Joint Patent Rights and other rights in Joint Technology to the extent applicable to the composition of such Clinical Candidate and all other Collaboration Compounds within that Collaboration Project, provided that ArQule shall not assert such rights against any Cubist Collaborator that discovers such Collaboration Compounds independent of any information (whether or not published) derived from either party or arising from the Collaboration; * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 21 <PAGE> (iv) ArQule retains the right to assert all ArQule Patent Rights and other rights in ArQule Technology against Cubist and any Cubist Collaborator; (v) ArQule shall grant Cubist an exclusive, worldwide, [ ]* license (with the right to sublicense) under any Joint Patent Rights and other rights in Joint Technology to the extent applicable to the use of such Clinical Candidate and all other Collaboration Compounds within that Collaboration Project with the identified Targets, provided that Cubist shall not assert such rights against any ArQule Collaborator that discovered such use independent of any information (whether or not published) derived from either party or arising from the Collaboration; and (vi) Cubist retains the right to assert all Cubist Patent Rights and other rights in Cubist Technology against ArQule and any ArQule Collaborator. Each party shall remain subject to the restrictions on Confidential Information set forth in Article 6. Cubist acknowledges that ArQule shall have the right [ ]* ArQule acknowledges that Cubist shall have the right (i) to screen and develop compounds other than the Collaboration Compounds within the terminated Collaboration Project, and (ii) to screen and develop those Collaboration Compounds if such compounds are independently discovered by a third party who, on its own initiative, offered those compounds to Cubist for use with the identified Target. 4. Ownership and Management of Intellectual Property. 4.1. Intellectual Property Developed Outside of Collaboration. Except as expressly set forth in this Agreement, neither party shall have any rights in Patent Rights and Technology that is developed or discovered by the other party prior to the Effective Date or outside of the Collaboration. For example, Cubist shall have sole ownership of all right, title, and interest in Targets and other Cubist Proprietary Research Materials, and ArQule shall * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 22 <PAGE> have sole ownership of all right, title, and interest in ArQule Compounds provided to Cubist in the Mapping Array Program. Each party shall have sole responsibility for and control over Patent Rights claiming any of its Technology that was developed or discovered prior to the Effective Date or outside of the Collaboration. Neither party shall have any right to review and comment on such Patent Rights of the other party. 4.2. Ownership of Intellectual Property Arising From the Collaboration. Ownership of Patent Rights and Technology arising from the Collaboration shall be allocated in the following manner: [ ]* Each party shall ensure that its employees, consultants, agents, and representatives are contractually required to assign to such party all Patent Rights and other rights in Technology arising from the Collaboration and to promptly disclose to such party all patentable inventions within that Technology. 4.3. Notice of Intellectual property Arising From the Collaboration. Each party shall provide prompt written notice to the Research Committee of the internal disclosure of any significant Technology developed by its personnel in connection with the Collaboration. 4.4. Responsibility for Patent Rights Arising from the Collaboration. ArQule shall be responsible for and shall control, [ ]*, the preparation, filing, prosecution, grant, and maintenance of any Patent Rights claiming only ArQule Technology and shall consult with Cubist on, and give Cubist a reasonable opportunity to review, all such filings to the extent they directly relate to the Collaboration. Cubist shall be responsible for and shall control, [ ]* the preparation, filing, prosecution, grant, and maintenance of all Patent Rights claiming only Cubist Technology and shall consult with ArQule on, and give ArQule a reasonable opportunity to review, * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 23 <PAGE> all such filings to the extent they relate directly to the Collaboration. In the case of Joint Technology, the Research Committee will decide whether to seek Joint Patent Rights claiming that Technology or to maintain that Technology as a trade secret. The Research Committee will also decide whether to seek Patent Rights claiming both ArQule Technology and Cubist Technology in one filing, which also constitutes a Joint Patent Right. If the Research Committee decides to seek any Joint Patent Rights, the parties shall jointly prepare, file, prosecute, and maintain such Patent Rights, and all related expenses shall become equally by the parties. Notwithstanding the foregoing, neither party shall file any Joint Patent Rights claiming the composition or use of any Active Compound in a Mapping Array until the Research Committee has properly designated that Active Compound as a Collaboration Compound in accordance with Subsection 3.3.(d) or 3.4.(e). 4.5. Assumption of Rights by Other Party. In the event that a party desires to decline responsibility for obtaining or maintaining Patent Rights in a country for any of its Technology that is developed or discovered in connection with the Collaboration, such party will notify the other party before taking such action and, upon request, will allow the other party to assume responsibility for, and all expenses relating to, the relevant Patent Rights in those countries; provided, however, that neither party shall have the right to seek patent protection for any Technology that a party has decided, in its discretion, to maintain as a trade secret. In the event that a party desires to cease further payment of patent-related expenses for a Joint Patent Right in any country, such party may assign to the other party all rights in that Joint Patent Right in such country and thereafter have no further obligation to pay such expenses. 4.6. Cooperation. Each party agrees to cooperate fully in the preparation, filing, prosecution, and maintenance of all Patent Rights claiming Technology arising from the Collaboration. Such cooperation includes, without limitation, (i) promptly executing all papers and instruments, or requiring its employees, consultants, and agents to execute such papers and instruments, as reasonable and appropriate so as to enable one or both parties to file, prosecute, and maintain such Patent Rights in any country; (ii) promptly informing the other party of matters that may affect the preparation, filing, prosecution, or maintenance of any such Patent Rights; and (iii) undertaking no actions that are potentially deleterious to the preparation, filing, or prosecution of any such Patent Rights. 4.7. Abandonment of Joint Patent Rights. In the event that the parties fail to complete a Collaboration Project due to lack of merit pursuant to Subsection 3.4.(i), the parties shall discuss in good faith 24 <PAGE> whether to abandon any unpublished patent applications within the Joint Patent Rights relating to that Collaboration Project. The parties recognize that publication of such Joint Patent Rights could adversely affect each of their interests after reversion occurs under Subsection 3.4.(i). 5. Research Materials. 5.1. Ownership of Research Materials. In the course of this Collaboration, one party (the "Provider") may transfer to the other party (the "Recipient") certain of its Research Materials. The Recipient acknowledges and agrees that such Research Materials are and shall be owned by the Provider. The Recipient agrees to execute and deliver any documents of assignment or conveyance to effectuate the ownership rights of the Provider in such Research Materials. [ ]* 5.2. Use and Transfer of Research Materials. Except as otherwise agreed by the Research Committee, the Recipient agrees to use Research Materials provided by the Provider solely for purposes set forth in this Agreement and shall not distribute such Research Materials to any third party other than its employees and consultants who are working on the Collaboration. 5.3. Additional Restrictions for Property Research Materials. In the case of Proprietary Research Materials furnished by a Provider, Recipient agrees (i) not to transfer such Proprietary Research Materials to any third party without the prior written consent of the Provider, (ii) to permit access to the Proprietary Research Materials only to its employees and consultants requiring such access, (iii) to inform such employees and consultants of the proprietary nature of the Proprietary Research Materials, and (iv) to take reasonable precautions, at least as stringent as those observed by Recipient to protect its own proprietary materials, to ensure that such employees and consultants observe the obligations of Recipient under this Section. 5.4. Disposition of Unused Research Materials. At the request of Provider, Recipient will return or destroy any unused Research Materials furnished by Provider. * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 25 <PAGE> 5.5. Compliance with Law. Recipient agrees to comply with all federal, state, and local laws and regulations applicable to the use, storage, disposal, and transfer of Research Materials furnished by Provider, including without limitation the Toxic Substances Control Act (15 USC 2601 et seq.) and implementing regulations (in particular, 40 CFR 720.36 [Research and Development Exemption]), the Food, Drug, and Cosmetic Act (21 USC 301 g et seq.) and implementing regulations, and all Export Administration Regulations of the Department of Commerce. Recipient assumes sole responsibility for any violation of such laws or regulations by Recipient or any of its Affiliates or Sublicensees. 5.6. Limitation of Liability. Any Research Materials delivered pursuant to this Agreement are understood to be experimental in nature and may have hazardous properties. Recipient should assume that the compounds are dangerous and should use appropriate precautions. [ .]* 6. Confidential Information. 6.1. Designation of Confidential Information. Confidential Information that is disclosed in writing shall be marked with a legend indicating its confidential status. Confidential Information that is disclosed orally or visually shall be documented in a written notice prepared by the Disclosing Party and delivered to the Receiving Party within thirty (30) days of the date of disclosure; such notice shall summarize the Confidential Information disclosed to the Receiving Party and reference the time and place of disclosure. 6.2. Obligations of Receiving Party. The Receiving Party agrees that it shall: (i) maintain all Confidential Information in strict confidence, except that the Receiving Party may disclose or permit the disclosure of any Confidential Information to its directors, officers, employees, consultants, and advisors who are obligated to maintain the confidential nature of such Confidential * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 26 <PAGE> Information and who need to know such Confidential Information for the purposes set forth in this Agreement; (ii) use all Confidential Information solely for the purposes of this Agreement; and (iii) allow its directors, officers, employees, consultants, and advisors to reproduce the Confidential Information only to the extent necessary to effect the purposes set forth in this Agreement, with all such reproductions being considered Confidential Information, 6.3. Exceptions. The obligations of the Receiving Party under Section 6.2. above shall not apply to the extent that the Receiving Party can demonstrate that certain Confidential Information: (i) was in the public domain prior to the time of its disclosure under this Agreement; (ii) entered the public domain after the time of its disclosure under this Agreement through means other than an unauthorized disclosure resulting from an act or omission by the Receiving Party; (iii) was independently developed or discovered by the Receiving Party without use of the Confidential Information; (iv) is or was disclosed to the Receiving Party at any time, whether prior to or after the time of its disclosure under this Agreement, by a third party having no fiduciary relationship with the Disclosing Party and having no obligation of confidentiality to the Disclosing Party with respect to such Confidential Information; or (v) is required to be disclosed to comply with applicable laws or regulations (such as disclosure to the FDA or the United States Patent and Trademark Office or to their foreign equivalents), or to comply with a court or administrative order, provided that the Disclosing Party receives prior written notice of such disclosure and that the Receiving Party takes all reasonable and lawful actions to obtain confidential treatment for such disclosure and, if possible, to minimize the extent of such disclosure. 27 <PAGE> 6.4. Return of Confidential Information. Upon the termination of this Agreement, or earlier at the request of the Disclosing Party, the Receiving Party shall return to the Disclosing Party all originals, copies, and summaries of documents, materials, and other tangible manifestations of Confidential Information in the possession or control of the Receiving Party, except that the Receiving Party may retain one copy of the Confidential Information in the possession of its legal counsel solely for the purpose of monitoring its obligations under this Agreement. 6.5. Survival of Obligations. The obligations set forth in this Article shall remain in effect for an item of Confidential Information for a period of ten (10) years after the date upon which a Receiving Party first received that Confidential Information, except that the obligation of the Receiving Party to return Confidential Information to the Disclosing Party shall survive until fulfilled. 7. Indemnification and Insurance. 7.1. General Indemnification. [ ]* (the "Indemnifying Party") shall indemnify and hold harmless the other party, its Affiliates, and their respective directors, officers, employees and agents (collectively, the "Indemnitees ") from and against all claims, expenses or liability of whatever nature arising from any default, act, omission or negligence of the Indemnifying Party, its agents or employees, or others exercising rights by, through, or under the Indemnifying Party, or the failure of the Indemnifying Party or such persons to comply with any applicable laws, rules, regulations, codes, ordinances or directives of governmental authorities, in each case to the extent the same are related, directly or indirectly, to the Collaboration described herein; provided, however, that in no event shall the Indemnifying Party be obligated under this section to indemnify the Indemnitees where such claim, expense or liability results solely from any omission, fault, negligence, or other misconduct of any of the Indemnitees. 7.2. Procedure. The Indemnitees agree to provide the Indemnifying Party with prompt written notice of any claim, suit, action, demand, or judgment for which indemnification is sought under this Agreement. If an Indemnitee fails to provide such notice within a reasonable time, and if such failure prejudicially affects the ability of the Indemnifying Party to defend such action, the Indemnifying Party shall be relieved of its liability to such Indemnitee under this Article 7. The Indemnifying Party agrees, at its own expense, to provide attorneys reasonably acceptable to the Indemnitees to * Confidential Treatment Requested: material has been omitted and filed separately with the Commission. 28 <PAGE> defend against any such claim. The Indemnitees shall cooperate fully with the Indemnifying Party in such defense and will permit the Indemnifying Party to conduct and control such defense and the disposition of such claim, suit, or action (including all decisions relative to litigation, appeal, and settlement); provided, however, that any Indenmitee shall have the right to retain its own counsel, at the expense of the Indemnifying Party, if representation of such Indemnitee by the counsel retained by the Indemnifying Party would be inappropriate because of actual or potential differences in the interests of such Indemnitee and any other party represented by such counsel. The Indemnifying Party agrees to keep the other party informed of the progress in the defense and disposition of such claim and to consult with such party with regard to any proposed settlement. 8. Term and Termination. 8.1. Term. This Agreement shall commence on the Effective Date and shall continue for a period of ten (10) years unless earlier terminated pursuant to this Article 8. 8.2.
