The above definitions are intended to encompass the defined terms in both the singular and plural tenses.

2. R&D PROGRAM

2.1 R&D Program. The scope of the collaboration between IBP and Diversa during the Research Period will be the areas of discovery, optimization, and development of Compound Sets in the Field, as well as all other aspects of the R&D Program, being defined in more detail in the Work Plan, which is hereby incorporated by reference into this Agreement. The Parties shall work together to identify compounds having potential use in the Field, and intend that IBP may obtain exclusive rights to such Compound Sets, subject to certain diligence and payment obligations as provided in this Agreement.

2.2 Research and Development Activities.

2.2.1 Staffing Level. In carrying out the R&D Program, Diversa shall devote [ * ] FTEs per year during the Research Period (the “Staffing Level”), and IBP shall pay Diversa for the services of such FTEs as set forth herein. Diversa shall not be obligated to utilize more than [ * ] FTEs per year during the Research Period in carrying out the R&D Program unless the Parties otherwise mutually agree. If IBP chooses to exercise its option under [ * ], the Parties shall mutually agree to the number of FTEs dedicated to the development of Compound Derivatives during the specified [ * ].

Notwithstanding the foregoing or anything contained herein to the contrary, the Staffing Level shall remain at [ * ] FTEs per year during the Research Period, unless the Parties mutually agree in writing to a change in the Staffing Level. Following the Research Period, if IBP requests that Diversa perform research services hereunder with respect to a compound within a Compound Set subject to a License (e.g., for supply of a Compound following the Research Period where such Compound is a member of a formerly Reserved Set), Diversa hereby agrees to discuss such request in good faith with IBP; provided, however, that Diversa shall not be obligated to agree to perform such services, and IBP shall be required to pay Diversa for any such services performed by Diversa FTEs at Diversa’s then applicable FTE rate.

2.2.2 Commercially Reasonable Efforts. Diversa and IBP shall use commercially reasonable efforts to perform the tasks for which each Party is responsible as set forth in the Work Plan, and to provide the facilities, materials, and equipment necessary to perform the R&D Program under the Work Plan.

2.2.3 Allocation of Responsibility. While the Parties intend to work collaboratively under the auspices of the RMC to specify the Party or Parties with responsibility for performing the specific research and development activities under the R&D Program, IBP shall be responsible for performing (or, subject to the limitations herein, arranging for Third Party subcontractors to perform) all research and development activities under the R&D Program that are not specified to be performed by Diversa. IBP shall be responsible for funding all research and development activities conducted hereunder, including those by Diversa or by IBP and by permitted Third Parties, if any, designated to conduct research and/or development activities in support of the R&D Program.

2.3 Limited Use of Materials Provided by Diversa. IBP agrees that it will use materials provided from Diversa’s environmental libraries pursuant to the Work Plan only for (i) screening such materials in connection with the R&D Program against assays selected by the RMC and/or (ii) conducting a medicinal chemistry program with respect to any particular Compound within such materials, and IBP agrees that it will not use such materials for any other purpose. IBP may not transfer such materials to any Affiliate, Sublicensee or Third Party subcontractor unless: (i) IBP notifies Diversa, through the RMC, of such transfer and (ii) IBP executes a agreement that governs the transfer of such materials that provides ownership of all inventions made or discovered using such materials to be allocated in a manner substantially consistent with the provisions of Article 5, as well as an obligation of confidentiality substantially similar to those set forth in Article 7, and a limitation on use of such materials to the performance of work under this Agreement. IBP and Diversa will separately inform the RMC in writing of the assays to be used in its screening of such materials prior to commencing such screening. IBP will provide Diversa with regular written reports identifying the extracts and assays used in such screening and the results of such screening. Diversa will provide IBP with regular written reports identifying the materials and assays used in such screening and the results of such screening. IBP will employ a system to track the identity and use of such materials and to ensure that such materials are maintained separately from any other materials used by IBP (or any Affiliate of IBP, its Sublicensee or Third Party subcontractor) and will provide Diversa with a detailed description of such system prior to the delivery of any materials by Diversa to IBP under the Work Plan.

2.4 Records During the Research Period and if applicable, the six-month period of Section 4.8, and continuing for a period of [ * ] thereafter, and/or as required by regulatory bodies, Diversa and IBP shall maintain records of the R&D Program (or cause such records to be maintained), both in notebooks and electronic forms that are generated for the R&D Program that are separate from any Third Party information, in sufficient detail and good scientific manner as will properly reflect all work done in the R&D Program and results achieved in the performance of the R&D Program. During the Research Period and continuing for a period of [ * ] thereafter, each Party shall allow the other Party to have reasonable access to all pertinent R&D Data generated by or on behalf of such Party with respect to any Lead Compound and Product. This retention of records may be extended if there is a legal proceeding pending (i.e., court action, or United States interference or opposition in any country involving Diversa’s or IBP’s intellectual property applicable to information within such records) where those records are reasonably required and a written request with the reason is provided to the other Party. Nothing herein shall require, or be construed to require, that either Party disclose to the other Party any of its Know-How, except to the extent necessary for the development and/or commercialization of Lead Compounds and Products.

2.5 Permitted Affiliates, its Sublicensees and Third Party Subcontractors. The Parties contemplate that either Party may have certain of the work to be performed by such Party in support of the R&D Program be performed by an Affiliate of such Party, or its Sublicensees, or any Third Party subcontractor hired for the sole purpose of performing such work, in accordance with the terms set forth herein so long as any inventions or discoveries made or discovered by an Affiliate of such Party, or its Sublicensees, or any Third Party subcontractor during the course of performing such work shall be owned by the appropriate Party as set forth in Article 5. Such Affiliate, Sublicensee or Third Party subcontractor may be involved in the following research and development activities: developing and performing assays, manufacturing Compound Derivatives and the Lead Compound, and running toxicology and stability studies. Each Party shall remain primarily responsible for the work to be performed by such Party, even if such work is performed by an Affiliate, Sublicensee, or Third Party subcontractor in support of the R&D Program under this Agreement. Either Party shall be permitted to involve Third Party subcontractors, its Sublicensees and/or its Affiliates with specific aspects of the R&D Program. In all events, however, the Party delegating any aspects of the R&D Program to Affiliates, Sublicensees or Third Party Subcontractor shall remain responsible hereunder for the activities of such Affiliates, Sublicensees, or Third Party subcontractors.

3. COMMITTEES; SELECTION OF COMPOUNDS AND COMPOUND DERIVATIVES

3.1 Organization.

3.1.1 Research Management Committee. IBP and Diversa shall establish a research management committee (the “RMC”) comprised of [ * ] persons (each, a “Committee Member”), [ * ] of whom shall be appointed by IBP and [ * ] of whom shall be appointed by Diversa. The RMC may invite other persons, including representatives of the Parties, to participate in meetings of the RMC, as appropriate, subject to appropriate obligations of confidentiality and non-use and provided that such persons shall not have the right to vote as Committee Members. The Parties may mutually agree to increase the number of Committee Members on the RMC if they determine that such increase would allow individuals with appropriate expertise to participate in the RMC, provided that after implementation of any increase in the number of Committee Members, each Party shall have an equal number of representatives on the RMC.

3.1.2 Steering Committee. In addition, IBP and Diversa shall establish a steering committee (the “Steering Committee”), consisting of the Chief Executive Officer of Diversa and the Chief Executive Officer of IBP, whose role shall be to oversee the functioning of the RMC and to resolve disputes within the RMC as described in Section 3.8.

3.1.3 Project Leaders. Diversa and IBP shall each name one of its RMC members to serve as a co-director of the R&D Program (each, a “Project Leader”). The Project Leaders shall oversee the implementation of the decisions and conclusions of the RMC with respect to the execution of the Work Plan, and address the day-to-day issues arising under the R&D Program.

3.2 Responsibilities. The purpose of the RMC shall be to plan, coordinate, and direct the research efforts related to the R&D Program and to ensure the execution of the Work Plan. Responsibilities to effect this purpose include, but are not limited to, the following:

3.2.1 Proposing Amendments to Work Plan. Either Party’s representatives on the RMC shall be permitted to propose amendments to the Work Plan. All such proposals to amend the Work Plan shall be in writing and delivered to each Committee Member prior to the RMC’s approval of such proposed amendment(s). Any material amendment(s) to the Work Plan shall be approved in writing by all Committee Members at a meeting of the RMC (or by written consent of all Committee Members) and, following approval of such amendment(s) by the RMC, shall be included in the minutes of such meeting. Specifically, any proposed change to the Staffing Level shall first be unanimously approved by the Committee Members and submitted to both Parties for written approval; however, if the RMC cannot agree to such a change to the Staffing Level, such issue shall be presented to the members of the Steering Committee as set forth in Section 3.8. Notwithstanding anything contained herein to the contrary, the Staffing Level shall not be changed during the Research Period absent the written approval of both Parties.

3.2.2 Review of Reports. At least quarterly, or at such other more frequent intervals as determined by the RMC, the RMC shall deliver to Diversa and IBP reports disclosing a complete compilation of all R&D Data and revisions to the Work Plan, as appropriate. The Parties will review such R&D Data to determine progress made on the R&D Program. Reports prepared by the RMC and delivered to each Party shall be subject to the confidentiality provisions contained herein.

3.2.3 Designation of Compound. If, as part of the research activities hereunder in accordance with the Work Plan during the Research Period, either Party invents or discovers a compound (i) that has not been derived from an existing Compound or from knowledge of the structure of an existing Compound and (ii) the structure of which has been elucidated as part of the Work Plan, as soon as practicable following the elucidation of the chemical structure of such compound sufficient to allow Diversa to determine whether such structure corresponds to an Excluded Compound (but in no event later than [ * ] after such event), such Party shall notify the RMC (as well as Diversa, if IBP is such Party) in writing of such compound’s structure to enable Diversa to determine whether such compound is an Excluded Compound. Within [ * ] following Diversa’s receipt of the structure information with respect to such compound, Diversa shall notify the RMC as well as IBP in writing as to whether or not such compound is an Excluded Compound (the “Notification”). If such compound is an Excluded Compound, then such compound shall not be deemed to be a Compound hereunder. If such compound is not an Excluded Compound, then such compound shall be designated as a Compound hereunder and shall comprise the first compound within the Compound Set associated with such Compound.

3.2.4 Designation of Compound Derivatives.

(a) If, as part of the research activities hereunder in accordance with the Work Plan, either Party invents or discovers a compound (i) that has been derived from an existing Compound or from knowledge of the structure of an existing Compound, either by [ * ], or by other means in the course of performing research pursuant to the Work Plan, including without limitation Compound Derivatives and (ii) the structure of which has been elucidated as part of the Work Plan, as soon as practicable following the elucidation of the chemical structure of such compound sufficient to allow Diversa to determine whether such structure corresponds to an Excluded Compound (but in no event later than [ * ] after such event), such Party shall notify the RMC (as well as Diversa, if IBP is such Party) in writing of such compound’s structure to enable Diversa to determine whether such compound is an Excluded Compound. Within [ * ] business days following Diversa’s receipt of the structure information with respect to such compound, Diversa shall notify the RMC (as well as IBP) in writing as to whether such compound is an Excluded Compound. If such compound is not an Excluded Compound and the RMC agrees that such compound otherwise satisfies the definition of a “Compound Derivative” with respect to the Compound from which such compound was originally derived, then such compound shall be deemed to be a Compound Derivative of such Compound and shall comprise an additional compound within the Compound Set associated with such Compound. If the RMC cannot agree whether such compound satisfies the definition of a “Compound Derivative,” or more specifically, if the RMC cannot determine the structure of the Active Substructure of the Compound that is associated with the Compound Set, and therefore cannot determine whether a compound is a Compound Derivative in such Compound Set within [ * ] days after Diversa has notified the RMC that the compound is not an Excluded Compound, then the Parties shall engage a mutually acceptable independent expert having a Ph.D. or equivalent degree in organic chemistry, with at least ten (10) years of experience in performing medicinal chemistry within the pharmaceutical industry, to determine whether the compound should be deemed to be a Compound Derivative of such Compound (an “Industry Expert”). The Parties shall select such Industry Expert within [ * ] after the expiration of the foregoing [ * ] period. Within [ * ] of its selection, the Industry Expert shall confer with the Parties for no longer than [ * ] after he or she receives information from each Party supporting its position on the structure of the Active Substructure or whether the compound should be deemed a “Compound Derivative” and make his or her determination. Each Party shall thereafter be bound by the decision of the Industry Expert as to whether the compound is deemed a Compound Derivative. The RMC shall maintain a document identifying the Compound Sets of this Agreement and amend such document from time to time with the addition of any new Compound Sets as identified during the Research Period (including, if applicable, any Compound Derivatives identified during the [ * ] period of Section 4.8), with a copy of such document, as amended from time to time being distributed to each Party within [ * ] following the end of the Research Period or if applicable, the six-month period of Section 4.8.

(b) However, if such compound is not an Excluded Compound and the RMC or the Industry Expert (whichever is applicable) determines that the compound does not otherwise satisfy the definition of a “Compound Derivative” with respect to the Compound from which such compound was originally derived, then such compound shall be deemed to be a new Compound with respect to which IBP shall be entitled to exercise its rights under Section 3.2.3 and shall comprise the first compound within a new Compound Set associated with such new Compound.

3.2.5 Compound Supply. As soon as a Compound has been designated under the procedures of Section 3.2.3 above, the RMC shall convene to decide the most efficient route to produce sufficient quantities of such Compound, not to exceed [ * ] of such Compound, to give IBP the opportunity to perform the minimum studies required to determine IBP’s interest in obtaining a License to a Compound Set associated with such Compound. If the RMC determines that the most efficient route to make such Compound is via [ * ], the RMC shall so notify IBP in writing, and IBP shall be responsible for producing sufficient quantities of the Compound as reasonably specified by the RMC. However, if the RMC determines that the most efficient route to make such Compound is via [ * ], the RMC shall so notify Diversa in writing, and Diversa shall be responsible for producing and delivering to IBP sufficient quantities of the Compound via [ * ] as reasonably specified by the RMC. IBP shall have a maximum of [ * ] from manufacture or receipt (as applicable) of such applicable quantities of the Compound to carry out such studies. If, within such [ * ] period, IBP determines that such Compound is of interest to IBP, IBP shall promptly notify Diversa in writing as to IBP’s desire to obtain a License to such Compound Set associated with such Compound. Subject to the terms and conditions of this Agreement, upon such written notification, if such Compound is not an Excluded Compound at such time, Diversa shall be deemed to grant a License to the Compound Set with respect to such Compound and Products based thereon as provided in Section 4.1. If Diversa is not so notified within such [ * ] period, however, IBP shall thereafter have no right to License such Compound or the Compound Set with respect to such Compound.

3.3 Meetings of the RMC and Steering Committee. The RMC shall meet in person at least once every calendar quarter during the Research Period and thereafter during the performance of the R&D Program, alternating the sites of such in-person meetings between Diversa’s facilities in San Diego, California and IBP’s facilities in Mountain View, California, or at such other times and locations as the RMC determines. Draft minutes for each meeting of the RMC shall be circulated within [ * ] following each meeting of the RMC. Such minutes shall include a summary of the matters discussed, decisions made, conclusions, and actions agreed upon by the RMC. The responsibility for preparing such meeting minutes shall alternate between the Project Leaders of IBP and Diversa, and such minutes will not be finalized until the Project Leader that did not prepare such minutes reviews and confirms the accuracy of such minutes, which shall take place within [ * ] of receipt of the minutes. The Steering Committee shall meet at such times, with such frequency, and at such locations as its members may agree from time to time.

3.4 Requirements for Action. At each RMC meeting, at least two Committee Members appointed by each Party shall constitute a quorum of the RMC, and decisions shall be made by unanimous vote. The Committee Members or Alternates of IBP shall collectively have one (1) vote on the RMC, and the Committee Members or Alternates of Diversa shall collectively have one (1) vote on the RMC.

3.5 Members. The initial Committee Members of the RMC shall be as follows:

Diversa Representatives IBP Representatives

[ * ] [ * ]

A Party may change one or more of its Committee Members, provided, however, that such person is technically qualified for the position as reasonably demonstrated by that Party. All appointments and withdrawals of appointment shall be made by written notice to the other Party. Each Party may designate in writing an alternate Committee Member (“Alternate”) with at least three (3) days prior notice to the other Party if the designated Committee Member cannot attend a meeting, provided, however, that such Alternate is technically qualified for the position as reasonably demonstrated by that Party. Any action taken with approval of an Alternate shall be as valid as if taken with the approval of the designated Committee Member.

3.6 Visits to Facilities. Committee Members and their designated representatives shall have reasonable opportunity to visit the facilities of each Party (and such Party’s Affiliates, its Sublicensees and permitted Third Party subcontractors hereunder) where activities under this Agreement are in progress, as reasonably required to execute the Work Plan, during normal business hours on a mutually agreeable date. Each Party shall bear its own expenses in connection with such site visits. Committee Members and their designated representatives shall be obligated to keep any and all information that such Committee Member or their designated representatives receives or reviews during such visits confidential, whether or not such information relates to the research and development activities overseen by the RMC under this Agreement. Each Party shall exert reasonable efforts to limit access by any permitted visitor to its facility to information that is unrelated to the Parties’ performance under this Agreement. Committee Members and their designated representatives shall have the right at any time during the visit to ask questions of and receive answers from personnel regarding their activities and findings under this Agreement.

3.7 Information Sharing. Each Party shall provide to the RMC information that is relevant and necessary to make decisions regarding the R&D Program and demonstrate efforts in furthering the research and development activities under the Work Plan in the form of a report (a “Progress Report”) no fewer than [ * ] prior to a scheduled RMC meeting. Each Progress Report shall, at a minimum, provide the status of any research, preclinical, and clinical development activities for compounds within a Compound Set and summarize any outstanding material issues associated with such development efforts and the likelihood of and timetable for commercialization of a Product based on any such compounds.

3.8 Dispute Resolution. If the RMC and Program Directors fail to reach agreement upon any matter, the dispute will be referred to the Steering Committee, which shall attempt to resolve such disputes informally. If such disputes cannot be resolved informally by the Steering Committee, the dispute will be resolved in accordance with the procedures set forth in Article 11.

3.9 Expenses. Diversa and IBP shall each bear all expenses of their respective RMC and Steering Committee members related to their participation on the RMC, attendance at RMC meetings, participation on the Steering Committee, and attendance at Steering Committee meetings.

For clarity, the period of identifying [ * ] for all compounds within a Compound Set that are not opted to be carried into the [ * ] expires at the end of the Research Period; the period for identifying [ * ] for all compounds within a Compound Set that is opted for further development during the [ * ] expires at the end of such period. If a License under Section 4.1.1 terminates, then the licenses under this Section 4.1.2 shall also terminate.

4.1.3 Diversa hereby grants to IBP (i) a nonexclusive, fully-paid, perpetual license to practice any and all Program Inventions that are not covered by [ * ] (or applications related thereto, so long as such applications are being prosecuted) made by IBP employees or consultants, either alone or jointly with Diversa employees or consultants, and [ * ], and (ii) a nonexclusive, fully-paid, perpetual license to practice any and all Program Inventions made by IBP employees or consultants either alone or jointly with Diversa employees or consultants, for IBP to carry out its responsibilities in accordance with this Agreement; provided however, that the license granted in this Section 4.1.3 shall not include a license to practice any Diversa Patent Rights. For the sake of clarity, [ * ].

4.2 Rights to Sublicense. Under each License, IBP shall have the right to grant sublicenses, through multiple tiers of sublicenses, provided that any such sublicense shall expressly provide for the Sublicensee to be bound by obligations consistent with those provided in this Agreement. If the Sublicensee receives materials provided by Diversa under Section 2.3 or if the Sublicensee performs work under the Work Plan as set forth in Sections 2.1 and 2.5, such sublicense shall provide for rights necessary for the Sublicensee to conduct and complete such activities on behalf of IBP in a manner consistent with the terms provided in this Agreement. IBP shall provide Diversa with prompt written notice of each sublicense agreement, as well as a copy of such sublicense agreement, after it is granted, provided that IBP may redact from such copy any terms not necessary to confirm compliance with this Section 4.2.

4.3 License Period. The term of the License with respect to each Compound Set, other than a Reserved Set, shall continue in force for the period (the “License Period”) ending on the earliest to occur of:

(a) the date IBP notifies Diversa that IBP does not intend to proceed with further development of [ * ] in accordance with the Work Plan, such notice to be made promptly after IBP makes such determination; or

(b) the date IBP notifies Diversa that IBP does not intend to continue to commercialize Product(s) based upon [ * ], such notice to be made promptly after IBP makes such determination; or

4.4 Reserved Sets. During the Research Period, IBP shall have the right to obtain a License with respect to as many Compound Sets as it identifies as being of interest to it pursuant to Section 3.2.4, subject to the provisions of Section 4.3 which provide for termination of the License Period for a given Compound Set if IBP [ * ] of compounds within the associated Compound Set. The Parties recognize that IBP [ * ] with respect to other Compound Sets. Accordingly, IBP may elect to [ * ] such Compound Set, by notifying Diversa in writing at the time [ * ]. For each compound within a Reserved Set, IBP may continue to [ * ] at the following times following its election to take a License for such Reserved Set:

*[ ]**	*[ ]**
*[ ]**	*[ ]**
*[ ]**	*[ ]**

IBP shall not be obligated to [ * ] with respect to a Reserved Set pursuant to this Section 4.4 [ * ] at any time after IBP [ * ] with a [ * ] below, as certified by IBP in a written notice to Diversa that IBP has [ * ]. After such written notice is received by Diversa, such Compound Set shall no longer be deemed to be a Reserved Set and the obligations under [ * ] with respect to such Compound Set shall [ * ] as if the [ * ], provided that Diversa shall be permitted to promptly request a reasonable amount of information from IBP to [ * ], which information IBP shall use its commercially reasonably efforts to supply to Diversa promptly on written request. However, after such notice is provided to Diversa, the [ * ] for such Compound Set shall [ * ] if any of the events described therein occurs. If IBP does not (a) [ * ] within [ * ] with respect thereto and (b) [ * ], then [ * ] with respect to such Reserved Set [ * ]. IBP shall not be entitled to re-designate a Compound Set as a Reserved Set (i) after [ * ] thereto pursuant to the foregoing sentence or (ii) following [ * ] of such Reserved Set as specified in this Section 4.4.

4.5 IBP Diligence Obligations. IBP shall have the sole and absolute discretion to make all decisions relating to marketing and other commercialization activities with respect to any Compound, compound within a Compound Set or any Product, provided that IBP may delegate the conduct and completion of such activities to its Affiliates, its Sublicensees, or any Third Party subcontractors, subject to the terms of this Agreement. However, notwithstanding the foregoing or anything to the contrary contained herein, each License to a Compound Set that is not a Reserved Set is expressly subject to (i) IBP’s continuing to use commercially reasonable efforts consistent with standards typically made by a [ * ] to proceed with the development of a Lead Compound in accordance with the Work Plan and (ii) following commercialization of a Product associated with such Lead Compound, IBP’s continuing to use commercially reasonable efforts consistent with standards typically made by a [ * ] to market and sell the Product. In the event that IBP no longer wishes to use such efforts, IBP shall promptly notify Diversa in writing of the same, and the License with respect to such Compound Set shall immediately terminate in accordance with the terms of this Agreement. In the event that Diversa believes that IBP is no longer using such efforts with respect to a Compound Set, then Diversa shall promptly notify IBP in writing of the same, and the Parties shall discuss such failure during the following [ * ]. If Diversa, after such [ * ] day period, believes that IBP has not remedied its failure to use such efforts, Diversa shall so notify IBP in writing, and IBP may then exercise its rights under Section 10.3 as a Defaulting Party thereunder to cure such default prior to Diversa’s terminating the License to such Compound Set. If, within the period specified in such notice, IBP has not cured such default with respect to such Compound Set, the License to such Compound Set shall immediately terminate.

4.6 Reversion of Rights to Diversa.

4.6.1 If the License Period with respect to the License to a Compound Set expires pursuant to the terms of this Agreement, including, without limitation, pursuant to the reasons set forth in Section 4.4 above, IBP shall have [ * ] and, at Diversa’s written request, shall transfer to Diversa or destroy all Confidential Information relating to the Compound Set (regardless of which Party generated such Confidential Information) within [ * ] after such expiration; provided, however, that IBP may retain one copy of such Confidential Information for the sole purposes of use in any litigation resulting from this Agreement or the activities undertaken pursuant to this Agreement. Upon the expiration of the License to a Compound Set, the Parties shall promptly initiate and continue negotiations, in good faith, for [ * ] to establish the terms of an [ * ] (the “Reversion License” ). Specifically, the Parties shall negotiate the [ * ] for such Reversion License based on, among other things, the [ * ] created (in whole or in part) by [ * ], the [ * ] of compounds within such reverted Compound Set or Product based on such Compound Set, and [ * ] such Compound Set or Product based therein. If the Parties cannot agree to the terms of the Reversion License within the [ * ] period, then the Parties shall engage a mutually acceptable independent expert with experience in valuing pharmaceutical compounds (the “Independent Expert”) to determine such [ * ] for the Reversion License, the costs of which shall be shared equally by the Parties. The Parties shall select such Independent Expert within [ * ] after the expiration of the foregoing [ * ] period. Within [ * ] of selection of such Independent Expert, each Party shall provide the Independent Expert with a reasonable amount of information such Party wishes the Independent Expert to consider as part of his or her decision. The Independent Expert shall confer with the Parties for [ * ] after he or she receives such information from each Party and make his or her determination at the end of such [ * ] period. Each Party shall thereafter be bound by the decision of the Independent Expert as to the amount that represents [ * ] to IBP for such Reversion License, and such matter shall not be subject to the dispute resolution procedure set forth in Article 11 hereof. [ * ] to be [ * ] hereunder for such Reversion License shall be subject to the accrual of [ * ]; provided however, that in no event shall [ * ] applicable. Such rate shall be determined as soon as practicable following the determination of the [ * ] hereunder for such Reversion License, and [ * ] shall begin to [ * ] after the date of such determination.

4.6.2 Notwithstanding anything contained herein to the contrary, [ * ] with respect to any reverted Compound Set until and unless [ * ] attributable to one or more compounds within such reverted Compound Set. With respect to each reverted Compound Set, [ * ] associated with the compound(s) within such reverted Compound Set that [ * ] receives, as well as [ * ], if any, of Products [ * ] that incorporate such compound(s), until [ * ] set pursuant to Section 4.6.1 above, together with all [ * ] thereon.

4.7 Manufacturing Rights.

4.7.1 As development progresses under the Work Plan for each compound within a Compound Set or Product such that IBP requires larger quantities of such compounds or Products manufactured in compliance with GMP, or other manufacturing standards, IBP shall notify Diversa of its need for preclinical, clinical or commercial supply, as applicable. If Diversa desires to be considered as a potential manufacturer, Diversa shall provide IBP with the requisite information to enable IBP to evaluate whether Diversa can manufacture compounds within a Compound Set or Products, as applicable, in accordance with regulatory requirements, IBP’s own standards for manufacture and other standards typically applicable in the pharmaceutical industry for the manufacture of pharmaceuticals. Selection of the manufacturer will be at IBP’s sole discretion. However, provided (i) IBP desires that the compound or Product in question be manufactured via a [ * ] route and (ii) Diversa possesses the ability to manufacture such compound or Product via [ * ], at a comparable price and in compliance with the relevant GMP, or other manufacturing and laboratory standards reasonably required by IBP, and (iii) Diversa is able to meet all other commercially reasonable requirements of IBP (e.g., regarding quality control, total cost, and capacity requirements)) IBP shall negotiate [ * ] with Diversa in good faith for [ * ] regarding the terms of a manufacturing agreement regarding such compound or Product (as applicable) [ * ], unless [ * ].

4.7.2 Subject to Sections 4.1.2 and 4.7.1 above, if IBP desires that the compound or Product in question be manufactured via a [ * ] but (a) IBP desires to manufacture such compound or Product internally or through a Third Party manufacturer, (b) Diversa notifies IBP that it is not interested in manufacturing such compound or Product (as applicable), (c) Diversa does not possess the ability to manufacture such compound or Product via [ * ] and in compliance with the relevant GMP, or other manufacturing standards, and other commercially reasonable standards required by IBP, or (d) Diversa is not a reasonably competitive prospective manufacturer of such compound or Product, then, subject to the Parties agreeing in good faith to reasonable compensation for all reasonable technology transfer costs and other reasonable Diversa costs as mutually agreed by the Parties. Subject to Section 4.1.2, IBP may engage a Third Party manufacturer for such compound or Product and may [ * ] to such Third Party solely to manufacture such compound or Product in accordance with this Agreement and the terms of such license; provided, however, that such [ * ] to such Third Party manufacturer under a [ * ] with the provisions of this Agreement. However, IBP shall [ * ] in good faith for [ * ] regarding the terms of any manufacturing agreement of such compound or Product (as applicable) via [ * ] prior to [ * ], unless Diversa notifies IBP in writing that it is not interested in manufacturing such compound or Product (as applicable). Prior to execution of any sublicense agreement with a Third Party manufacturer, IBP shall provide Diversa with a copy of such sublicense agreement, provided that IBP may redact from such copy any terms not necessary to confirm compliance with the provisions of Section 4.2 and this Section 4.7.2. Within [ * ] of receipt of such copy, Diversa shall have the right to approve such sublicense agreement, such approval not to be unreasonably withheld. Diversa’s failure to respond within [ * ] of receipt of the copy of the sublicense agreement shall constitute approval of the sublicense agreement.

4.8 Extension of Research Period. Notwithstanding the [ * ] period to extend the Research Period set forth in Section 10.1, IBP shall have the option to continue developing Compound Derivatives of the compounds within the Compound Sets existing at the end of the originally scheduled Research Period for up to [ * ] as an extension of the Research Period for such Compound Sets. Specifically, at least thirty (30) days before the end of the initial [ * ] Research Period, IBP shall identify to Diversa the Compound Sets for which IBP wishes to continue developing Compound Derivatives, and the Parties can conduct such work for up to [ * ] thereafter. During such extended Research Period, IBP shall not have the right to designate Compounds as set forth in Section 3.2.3 or Compound Derivatives as set forth in Section 3.2.4 that are not Compound Derivatives within the Compound Sets identified by IBP. Any Compound Derivatives made, discovered or invented during the extended Research Period shall be subject to all applicable terms of this Agreement regarding Compound Derivatives, including without limitation the provisions regarding the payment to Diversa of milestones and royalties.

4.9 Compound Exclusivity; Non-Compete. With respect to each Compound Set for which IBP has a License that has not terminated, Diversa shall not itself develop or commercialize products based upon or containing any compounds within such Compound Set, or grant to any Third Party a license under the Diversa Technology or collaborate with any Third Party, to develop or commercialize products based upon or containing compounds within such Compound Set. In addition, for a period of [ * ] following the Effective Date, Diversa shall not outlicense any Diversa Technology to a Third Party company (i) whose primary business is the research, development and commercialization of novel drugs in the Field and (ii) who owns, either directly or through one or more wholly-owned subsidiaries, patents related to all of the following: [ * ]

5. INTELLECTUAL PROPERTY RIGHTS

5.1 Intellectual Property Ownership. All Program Inventions shall be owned by Diversa, except that IBP shall own all Program Inventions that relate solely to (a) [ * ] and (b) [ * ] and that are designated by the RMC as proprietary [ * ]. Each Party shall notify promptly the other Party, in writing, of any Program Invention. Such written notification shall provide the [ * ], to the extent known, of any compounds made, discovered or invented, and all other data relevant to determining the patentability and inventorship of such Program Invention.

5.1.1 Each Party shall continue to own all intellectual property owned by such Party prior to the Effective Date.

5.1.2 Each Party shall have the right to secure patent protection for the Program Inventions owned by it, in accordance with this Section 5. Each Party shall (and shall cause its applicable Affiliates to) make such assignments and take such other actions as may be necessary or appropriate to effect the ownership of intellectual property rights in accordance with this Section 5.1.

5.2 Filing, Prosecution and Maintenance of Patents.

5.2.1 Except as provided in this Section 5.2 or Section 5.5, each Party shall have the sole right, at its own expense, to control the filing, prosecution, maintenance, defense and enforcement of its own patents and patent applications.

5.2.2 Diversa shall confer with IBP regarding its plans to secure patent protection for any Program Inventions owned by Diversa which cover the composition, manufacture or use of Compounds, Compound Derivatives, Active Substructures and/or Products (“Compound Patents”). The Parties shall seek to agree on the patent strategy to be followed in securing such protection.

(a) Diversa shall select outside counsel to prepare, prosecute, and maintain each patent application and resulting patent within the Compound Patents, and IBP shall reimburse Diversa for [ * ] incurred in connection with such work. The Parties shall have equal access to such outside counsel. The Parties shall seek to agree on the prosecution of patent applications within the Compound Patents, but in the event of disagreement, Diversa shall control the prosecution. If IBP is dissatisfied with the prosecution of patent applications within the Compound Patents by the outside counsel selected by Diversa, IBP shall so inform Diversa in writing, and such patent applications shall be transferred to a different, mutually-acceptable outside counsel. Diversa shall provide IBP a list identifying at least three (3) alternative outside counsel, identify its first preferred choice within such list and request approval of its first preferred choice from IBP. IBP’s approval shall not be unreasonably withheld. If IBP has a reasonable basis to disagree with the selection of such outside counsel, the Parties shall negotiate, in good faith, the selection of an alternative outside counsel from the remaining outside counsel identified in the list. The Parties shall confer with respect to the list of countries outside the United States in which patent applications within the Compound Patents will be filed and maintained, and with prior notice, IBP may decline to pay any fees or expenses with respect to individual countries. In such case, Diversa shall make the sole decision about whether to pursue such patent applications in such countries, at its sole expense.

(b) Diversa shall furnish IBP with copies of draft patent applications and correspondence relating thereto to and from governmental patent agencies and other authorities which relate to Compound Patents. Diversa shall permit IBP to offer its comments thereon before Diversa makes a submission to a governmental patent agency or other authority which could materially affect the scope or validity of the patent coverage with respect to such Compound Patent, and IBP shall offer its comments promptly; provided IBP’s failure to respond within [ * ] of receipt of the draft patent application or correspondence relating thereto shall be deemed approval of such patent application or correspondence. Diversa shall seek to incorporate IBP’s comments in its patent prosecution activities, and to the extent that it declines to incorporate such comments, shall explain to IBP its reasons for such decision. Diversa shall also keep IBP informed of its patent prosecution for all Compound Patents that are subject to the License of Section 4.1, and shall confer reasonably with IBP and provide IBP with copies of any patent applications and correspondence related thereto to and from governmental patent agencies or other authorities to the extent reasonably requested by IBP to monitor the scope and nature of the rights to which IBP holds a license under this Agreement.

(c) If Diversa decides not to file any Compound Patent, or to abandon any patent application, patent or other intellectual property right covering such matter, either on a worldwide basis or in particular countries, it shall provide IBP reasonable written notice of such intention, and shall permit IBP, at the sole option and expense of IBP, to file, prosecute and maintain such patent application, patent, or other intellectual property right in the name of IBP. In such event, Diversa shall cooperate fully with IBP and shall provide to IBP whatever assignments and other documents that may be needed in connection therewith.

(d) IBP may, at its election and from time to time, disclaim any special rights under paragraph (a) above with respect to particular patent application(s) included within Compound Patents, in which case Diversa shall assume exclusive control over the prosecution of such application(s) at its sole expense. In such case, IBP shall retain the rights set forth elsewhere in this Section 5.2 with respect to patent prosecution covering other Program Inventions.

5.3 Cooperation of the Parties. Each Party agrees (and will cause any of its Affiliates) to cooperate fully in the preparation, filing, prosecution and maintenance of any patent rights with respect to Program Inventions. Such cooperation shall include but not be limited to:

(a) executing all papers and instruments, or using reasonable efforts to cause its employees or agents to execute such papers and instruments, so as to effectuate the ownership of intellectual property rights set forth in Section 5.1 and to enable the other Party to file and to prosecute patent applications and to maintain patents in any country;

(b) promptly informing the other Party of any matters coming to such Party’s attention that may affect the preparation, filing or prosecution of any such patent applications or the maintenance of any such patents; and

(c) undertaking no actions that are potentially deleterious to the preparation, filing or prosecution of such patent applications or to the maintenance of such patents.

5.4 Potential Assignments To IBP. Diversa recognizes that IBP has a commercial interest in determining the patent protection for Compounds, Compound Derivatives, Active Substructures and Products, and enforcing any patents which cover the composition, manufacture or uses thereof. In the event IBP makes a determination to commence human clinical trials of any particular Product or Product(s), the Parties will discuss whether it is practical to assign to IBP any of the patent applications or patents arising from Program Inventions that are specific to the Product in question, or the Compound or Compound Derivative contained therein, or related compounds within the same Active Substructure. In the alternative, the Parties shall consider whether it is practical to create and assign to IBP divisional patent properties which are specific to such matters. Any such assignments shall occur only by mutual agreement of the Parties in the future, but Diversa agrees to review opportunities for such assignment in good faith, and without further consideration to be paid by IBP (except that IBP would become responsible for any costs of assignment and the future prosecution and maintenance of any patent applications and patents which are assigned).

5.5 Infringement by Third Parties.

5.5.1 Notice. Each Party shall promptly notify the other Party in writing of any competitive products sold by Third Parties or other activities by Third Parties of which they become aware that appear to infringe any patent or patent application included within the Patent Rights of the other Party.

5.5.2 IBP Actions. IBP shall have the first right to bring and control, by counsel of its own choice and at its own expense, any action or proceeding with respect to infringement of any IBP Patent Rights, as well as any Compound Patents subject to a License at the time of commencement of any such action or proceeding or which issue during the pendency of any such action or proceeding. If IBP requests Diversa to enforce or to authorize IBP to enforce other Diversa Patent Rights that may be infringed by the activities of a Third Party, then Diversa will consider in good faith bringing such action or authorizing IBP to bring such action. Diversa shall have the right, using counsel of its own choice and at its own expense, to participate in any such action regarding the Diversa Patent Rights. Upon written notice to Diversa, IBP may require Diversa to participate in such action as a necessary party, at IBP’s expense. If IBP fails to bring an action or proceeding with respect to any such Diversa Patent Rights within (a) [ * ] following the notice of alleged infringement or (b) [ * ] before the time limit, if any, set forth in the appropriate laws and regulations for the filing of such actions, whichever comes first, Diversa shall have the right to bring and control any such action, at its own expense and by counsel of its own choice, and IBP shall have the right, using counsel of its own choice and at its own expense, to be represented in any such action.

5.5.3 Diversa Actions. Diversa shall have the right to bring and control, by counsel of its own choice, any action or proceeding with respect to infringement of any Diversa Patent Rights which are not subject to a License at the time of commencement of such action or proceeding.

5.5.4 Cooperation; Awards. In the event a Party bring an infringement action which relates to Program Inventions, the other Party shall (and shall endeavor to cause its Affiliates, Sublicensees and Third Party subcontractors, if appropriate, to) cooperate fully, including if required to bring such action, the furnishing of a power of attorney. Neither Party shall have the right to settle any patent infringement litigation under this Section 5.5 in a manner that diminishes the rights of the other Party without the prior written consent of the other Party. Except as otherwise agreed to by the Parties as part of a cost sharing agreement, any recovery realized as a result of such litigation, after reimbursement of any litigation costs of Diversa and IBP, shall be shared between the Parties so that the Party bringing such action retains [ * ] of such amount and the other Party retains [ * ] of such amount.

5.6 Third Party Claims of Infringement. Diversa and IBP shall promptly notify the other in writing of any allegation by a Third Party that the exercise of the rights granted to IBP under this Agreement or the activities of either Party under this Agreement infringes or may infringe the intellectual property rights of such Third Party. Each Party will use commercially reasonable efforts (and will endeavor to cause its Affiliates to use commercially reasonable efforts) to cooperate with the other Party to resolve or defend against any such claims.

In the event that such publication no longer publishes such rates, another financial publication mutually agreed on by the Parties shall be substituted or one shall be chosen by an investment banker/analyst mutually agreed on by the Parties.

6.5.3 Diversa shall pay any and all taxes levied on account of royalties and other payments it receives under this Agreement. If laws or regulations require that taxes be withheld, IBP will deduct such taxes from the amount due to Diversa, pay such taxes to the proper tax authority, and send evidence of the obligation together with proof of payment to Diversa promptly after making such payment.
