YAMANOUCHI shall have a reasonable period of time during which to make its selection of such replacement Target; provided that YAMANOUCHI shall promptly notify ICAgen of its selection and shall release all Targets not selected as the replacement upon the earlier of its selection of a replacement or [**] after ICAgen makes the list available. In the event of such a replacement, all rights with respect to the Initial Targets, and all rights with respect to the Targets not selected as the replacement Target from the list made available by ICAgen, shall revert to ICAgen, and YAMANOUCHI shall cease using any Confidential Information and Substances (as defined in Section 2.9) of ICAgen relating to the Initial Targets and all non-selected Targets. In the event of such a replacement, a new time line and a new Annual Research Plan shall be mutually agreed by the Parties with respect to the replacement Target.

(c) YAMANOUCHI Termination Right. If either (i) YAMANOUCHI declines to select a replacement Target from the list of additional Targets provided by ICAgen because YAMANOUCHI reasonably determines that none of the additional Targets on the list is reasonably compatible with any YAMANOUCHI research strategy, or (ii) Yamanouchi selects a replacement Target and any mutually agreed upon research milestone with respect to the replacement Target is not achieved (as determined by the Joint Research Committee) within the time lines mutually agreed upon, YAMANOUCHI shall be entitled to terminate this Agreement upon written notice to ICAgen; provided that YAMANOUCHI shall continue to fund the Research Program in accordance with Section 2.5 for at least ninety (90) days after such written notice or until the scheduled time for completion of the Research Program, whichever is earlier.

(d) Sublicense Option. If ICAgen holds the right to screen against a Target pursuant to a license from a Third Party, ICAgen shall make available to YAMANOUCHI the option to enter into a sublicense with ICAgen under such license, which option shall be exercisable during the term of this Agreement at any time from and after (i) the identification in the Research Program of a Pre-lead Compound relating to such Target, and (ii) the determination by the Parties that such Target is a Valid Target. Any such sublicense shall be exclusive (except as to ICAgen) in the Primary Field and non-exclusive in the Secondary Field, and shall conform to any requirements of the license to ICAgen with respect to sublicenses. Any such sublicense shall terminate upon the first to occur of: (i) the termination or expiration of this Agreement; (ii) YAMANOUCHI ceasing to use commercially reasonable efforts (as specified in Section 4.1(a)) to develop and commercialize a Clinical Compound or Product based on such Pre-lead Compound, the discovery or development of which was covered by a Valid Claim of any patents or patent application(s) which are the subject of the sublicense; (iii) a notice of termination from YAMANOUCHI to ICAgen; or (iv) expiration or termination of the underlying license; provided that ICAgen shall use commercially reasonable efforts to maintain such underlying license in effect in order to avoid a termination of the sublicense under the immediately preceding clause (iv) above.

2.5 Funding of the Research Program.

(a) Funding Obligation. For each year during the term of the Research Program, YAMANOUCHI (i) shall pay ICAgen $[**] for ICAgen’s activities in connection with the Research Program and (ii) shall reimburse ICAgen for up to $[**] of out-of-pocket Third Party costs incurred by ICAgen in connection with the Research Program. For purposes of this Section 2.5(a), out-of-pocket Third Party costs for which ICAgen shall be entitled to reimbursement shall be the amounts billed directly to ICAgen by Third Parties.

(b) Payments. The $[**]annual payment specified in Section 2.5 (a) shall be paid in equal quarterly installments in advance on the first day of January, April, July and October of each calendar year. Any payment for a portion of a calendar quarter shall be made on a pro rata basis. ICAgen shall provide YAMANOUCHI with a report setting forth the costs incurred by it in the Research Program (the “Research Program Costs”) during each calendar quarter within thirty (30) days after the end of the calendar quarter, such report to be in reasonable detail sufficient for YAMANOUCHI to confirm that such costs were incurred in the conduct of the Research Program. Reimbursements of Third Party costs specified in Section 2.5(a) shall be paid on a quarterly basis within 30 days after the receipt by YAMANOUCHI of an invoice, which shall be delivered within thirty (30) days after the end of each calendar quarter, which shall itemize the amount of out-of-pocket Third Party costs incurred by ICAgen during the calendar quarter and which shall be accompanied by a receipt or other reasonable supporting documentation for each expense item. All payments shall be made via wire transfer to a bank account designated by ICAgen from time to time. In the event that, as of the expiration or termination of the Research Program, the aggregate amount of funding provided by YAMANOUCHI pursuant to subsection (a) (exclusive of reimbursements for Third Party costs) exceeds the aggregate Research Program Costs reported by ICAgen, then ICAgen shall return to YAMANOUCHI an amount equal to such excess for purposes of enabling YAMANOUCHI to document research expenses exempt from withholding taxes in Japan. YAMANOUCHI shall thereafter promptly pay back to ICAgen the amount returned to YAMANOUCHI, less any withholding tax applicable to such payment. For example, if Research Program Costs total $[**] and YAMANOUCHI i shall have provided $[**] pursuant to subsection (a), ICAgen shall return $[**] to YAMANOUCHI and YAMANOUCHI will pay $[**] to ICAgen and $[**] to the tax authorities.

(b) Inspection Right. ICAgen and YAMANOUCHI each shall have the right, during normal business hours and upon thirty (30) days prior written notice, and subject to such reasonable procedures as the other Party may require, to inspect all such records of the other Party solely and directly relating to the Research Program to the extent reasonably required for the performance of its obligations under this Agreement. ICAgen and YAMANOUCHI each shall maintain such records and the information of the other Party contained therein in confidence in accordance with Section 12 and shall not use such records or information except to the extent otherwise permitted by this Agreement.

2.8 Exclusivity.

(a) Exclusivity Commitment. During the Exclusivity Period (as defined below), neither Party nor any of its Affiliates (other than (i) an Affiliate that controls such Party or (ii) any Affiliates of such Affiliate that controls such Party and that are not controlled by such Party) shall

engage in any research or drug development activities, either for their own benefit or with, for the benefit of or sponsored by any Third Party, with respect to a product in the Primary Field whose activity is based upon modulation of a Target; provided, however, that nothing in this Section 2.8 shall preclude a Party from developing and commercializing Clinical Compounds and Products based thereon as contemplated by this Agreement or preclude ICAgen from developing and commercializing anywhere in the world compounds in the Field whose activities are based upon the modulation of Targets to which rights have reverted to ICAgen under Section 2.4(b) or from developing and commercializing anywhere in the world Advanced Lead Compounds, Selected Hit Compounds, Pre-Lead Compounds and Products based thereon in the Field as contemplated under Section 3.5(c).

(b) Exclusivity Period. For purposes of this Agreement, the “Exclusivity Period,” shall mean the period beginning on the Effective Date and ending on the [**]; provided, however, that if on the [**] either Party is using commercially reasonable efforts (as specified in Section 4.1(a)) to develop and/or commercialize a Clinical Compound and a Product based thereon in the Primary Field, the Exclusivity Period to which the other Party is committed shall be extended to end on the [**].

(c) Termination of Exclusivity Period. Notwithstanding Section 2.8(b), the Exclusivity Period to which either Party is committed shall terminate if at any time after the other Party first commences a program to develop and commercialize Clinical Compounds and Products based thereon in the Primary Field under this Agreement, such other Party subsequently terminates or abandons all of its programs to develop and commercialize Clinical Compounds and Products based thereon in the Primary Field as contemplated by this Agreement.

2.9 Material Transfer. In order to facilitate the Research Program, either Party may provide to the other Party certain [**] (“Substances”) owned by or licensed to the supplying Party (other than under this Agreement) for use by the other Party in furtherance of the Research Program. In addition, each Party shall use reasonable efforts to provide to the other Party up to [**] of each Pre-lead Compound and each related compound subsequently chemically synthesized under the Research Program (“Compound Samples”). Until the first to occur of (i) the end of the Clinical Compound Selection Period, or (ii) the termination of this Agreement, all Compound Samples shall be used by the receiving Party solely in connection with the Research Program and the development activities contemplated by this Agreement. Thereafter, each Party may use Compound Samples provided by the other Party for all research and commercial purposes (such as inclusion of such compounds in compound libraries for screening purposes) without obligation to the other Party, provided that: (x) the Party receiving a Compound Sample may not utilize such Compound Sample if such compound is a Preclinical Compound or Clinical Compound that the other Party is developing or commercializing or a Back-up Compound for any Preclinical Compound or Clinical Compound that the other Party is developing or commercializing, and (y) the Party receiving a Compound Sample shall not in any case utilize such Compound Sample to develop any product based thereon outside the Field if the compound’s primary mechanism of action is to modulate a Target against which such compound was identified as having activity in the Research Program, and (z) if within five years after the term of the Research Program the Party receiving a Compound Sample commences development or commercialization of the compound in the Field and such compound has as its primary mechanism of action the modulation of a Target against which such compound was identified as having activity in the Research Program or thereafter during the Exclusivity Period, such Party shall be required to pay (i) milestones to the other Party with respect to such compound as provided in Section 6.2, if the other Party is ICAgen

(treating such compound as a Preclinical Compound for purposes of Section 6.2(a) and as a Clinical Compound for purposes of Sections 6.2(b) and (c)) and (ii) royalties as provided in Section 6.3(a) or (b) (treating such compound as a Product for purposes of Section 6.3(a) or (b)). Except as otherwise provided under this Agreement, all Substances delivered to the other Party, shall not be used for the benefit of or delivered to any Third Party without the prior written consent of the supplying Party. The Substances and Compound Samples supplied under this Section 2.9 shall not be used in research or testing involving human subjects and shall be used with prudence and appropriate caution in any experimental work, since not all their characteristics may be known. THE SUBSTANCES AND COMPOUND SAMPLES ARE PROVIDED “AS IS” AND WITHOUT ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR ANY PARTICULAR PURPOSE OR ANY WARRANTY THAT THE USE OF THE SUBSTANCES OR COMPOUND SAMPLES WILL NOT INFRINGE OR VIOLATE ANY PATENT OR OTHER PROPRIETARY RIGHTS OF ANY THIRD PARTY.

2.10 Liability. Each Party shall be responsible for, and hereby assumes, any and all risks of personal injury or property damage attributable to the negligent or willful acts or omissions, during the term of the Research Program, of that Party or its Affiliates, and their respective directors, officers, employees and agents.

2.11 Term and Termination of Research Program.

(a) The Research Program shall terminate upon the earlier to occur of (i) the termination of this Agreement or (ii) three years after the Effective Date. If YAMANOUCHI desires to extend the Research Program, it must provide ICAgen with a proposal as to such

extension at least six months prior to the termination of the Research Program, which proposal shall include a description of the proposed activities and their scope and a description of the proposed funding for the proposed activities; provided that if, due to ICAgen’s inability to accomplish the Third Target Milestone within the term of the Research Program, YAMANOUCHI provides ICAgen with a proposal for extension less than six months prior to the termination of the Research Program, then ICAgen shall negotiate with YAMANOUCHI in good faith regarding terms for YAMANOUCHI’s proposed extension. The Research Program only may be extended upon the mutual written consent of both Parties.

(b) Upon termination of the Research Program pursuant to Section 2.11(a), each Party shall promptly transfer to the other Party all relevant records and materials in a receiving Party’s possession or control containing Confidential Information of the disclosing Party to which the receiving Party does not retain rights hereunder and furnish to the supplying Party all Substances (but not Compound Samples) provided in connection with the Research Program.

(c) Except as provided in this Section 2.11, termination of the Research Program shall not terminate any other rights or obligations of the Parties under this Agreement other than those set forth in this Section 2.

Notwithstanding the foregoing, ICAgen may not elect to develop or commercialize a Primary Field Preclinical Compound, Clinical Compound or Product based thereon for an indication in the Primary Field if YAMANOUCHI is developing or commercializing another Clinical Compound or a Product based thereon for the same indication in the Primary Field.

(b) Secondary Field Preclinical Compounds. The provisions of this subsection (b) shall apply with respect to (x) each Preclinical Compound that is determined by the Joint Research Committee to be reasonably likely to have an indication in the Secondary Field (but not an indication in the Primary Field) (each such compound, a “Secondary Field Preclinical Compound”), (y) certain Non-Selected Primary Field Preclinical Compounds, and (z) certain Abandoned Primary Field Preclinical Compounds:

(i) ICAgen Right to Elect for Rest of World. ICAgen may, at any time during the Clinical Compound Selection Period, elect to develop and commercialize in the Secondary Field in the Rest of the World each Secondary Field Preclinical Compound.

(ii) YAMANOUCHI Right to Elect for Asia. YAMANOUCHI may, at any time during the Clinical Compound Selection Period, elect to develop and commercialize in the Secondary Field in Asia each Secondary Field Preclinical Compound.

(iii) ICAgen Right to Elect for Entire World. ICAgen may, during the [**] period following the [**], elect to develop and commercialize in the Secondary Field in the Entire World each Secondary Field Preclinical Compound if, during the Clinical Compound Selection Period, (A) ICAgen has elected to develop and commercialize such Secondary Field Preclinical Compound in the Rest of the World in the Secondary Field, and (B) YAMANOUCHI has not elected to develop and commercialize such Secondary Field Preclinical Compound in the Secondary Field in Asia as provided in subsection (b)(ii), or YAMANOUCHI has provided a YAMANOUCHI Abandonment Notice for such Secondary Field Preclinical Compound.

(iv) YAMANOUCHI Right to Elect for Entire World. YAMANOUCHI may, during the [**] period following the [**], elect to develop and commercialize in the Secondary Field in the Entire World each Secondary Field Preclinical Compound, Non-Selected Primary Field Preclinical Compound and Abandoned Primary Field Preclinical Compound if, during the Clinical Compound Selection Period, (A) YAMANOUCHI has elected to develop and commercialize such Secondary Field Preclinical Compound, Non-Selected Primary Field Preclinical Compound or Abandoned Primary Field Preclinical Compound in Asia in the Secondary Field, and (B) ICAgen has not elected to develop and commercialize such Secondary Field Preclinical Compound, Non-Selected Primary Field Preclinical Compound or

Abandoned Primary Field Preclinical Compound in the Secondary Field in the Rest of the World as provided in subsection (b)(i), or ICAgen has provided an ICAgen Abandonment Notice for such Secondary Field Preclinical Compound, Non-Selected Primary Field Preclinical Compound or Abandoned Primary Field Preclinical Compound.

(c) Abandonment. If pursuant to Section 2.12(a) or (b) either Party elects to develop and commercialize a Preclinical Compound and thereafter at any time ceases, in all Major Countries in the applicable Territory, to use commercially reasonable efforts (as specified in Section 4.1) to develop and commercialize a Clinical Compound and a Product based thereon, it shall promptly so notify the other Party (a “YAMANOUCHI Abandonment Notice” or an “ICAgen Abandonment Notice”, as the case may be). Such notice shall indicate whether the abandonment applies to the Primary Field, the Secondary Field or to all Fields, as applicable.

(d) Notice of Election. If a Party desires to make an election pursuant to Section 2.12(a) or (b), it may do so by giving notice thereof to the other Party within the applicable time period specified in such Sections or any extension of the applicable time period that is agreed upon in writing by both Parties. If a Party fails to make an election by giving such notice within the applicable time period (or such a mutually agreed upon extension thereof), the right to make such election shall expire and be of no further force or effect. If either Party desires to make any election pursuant to Section 2.12(a) or (b) that it would be entitled to make pursuant to Section 2.12(a) or (b) but for the fact that the compound with respect to which it desires to make such election has not been formally designated a Preclinical Compound, then such Party shall be entitled to make the election; provided that such Party shall have given the other Party [**] prior written notice of its intent to make such election and the other Party has not agreed in writing during such [**] period to

cooperate with such Party in promptly causing the Joint Research Committee to designate such compound a Preclinical Compound.

(e) Cessation of Efforts. If a Party believes that the other Party has ceased, in all Major Countries in the applicable Territory, to use commercially reasonable efforts (as provided in Section 4.1(a) or (b), as applicable) to develop or commercialize a Clinical Compound or a Product based thereon, it may so notify the other Party. If the other Party does not respond within [**] of such notice by giving the first Party an Abandonment Notice or providing the first Party with information relating to the development or commercialization of the Clinical Compound or the Product based thereon at issue sufficient to satisfy the first Party that the other Party is using the requisite commercially reasonable efforts, the first Party may submit the issue of whether the other Party has ceased, in all Major Countries in the applicable Territory, to use commercially reasonable efforts to develop or commercialize such Clinical Compound or Product based thereon, to arbitration in accordance with Section 15.14. If it is determined in such arbitration that the other Party has ceased to use commercially reasonable efforts to develop or commercialize the Clinical Compound or Product based thereon that is the subject of the arbitration, such other Party shall be deemed to have given an Abandonment Notice as to such Clinical Compound and Product based thereon as of the date of the decision in the arbitration.

(f) YAMANOUCHI Reversion of Rights. Subject to the provisions of Sections 2.9 and 3.5(c), (i) if a YAMANOUCHI Compound, a YAMANOUCHI Selected Hit Compound, a YAMANOUCHI Pre-lead Compound, a YAMANOUCHI Lead Compound or a YAMANOUCHI Advanced Lead Compound is not selected as a YAMANOUCHI Selected Hit Compound, a YAMANOUCHI Pre-Lead Compound, a YAMANOUCHI Lead Compound, a YAMANOUCHI Advanced Lead Compound or a YAMANOUCHI Preclinical Compound,

respectively, all rights thereto shall revert solely to YAMANOUCHI; (ii) if an Analog synthesized by YAMANOUCHI under the Research Program is not selected as a YAMANOUCHI Lead Compound or a YAMANOUCHI Advanced Lead Compound, all rights thereto shall revert to YAMANOUCHI; (iii) if a YAMANOUCHI Preclinical Compound is not selected for development and commercialization by either Party pursuant to this Section 2.12, all rights thereto shall revert to YAMANOUCHI; and (iv) if a YAMANOUCHI Preclinical Compound has been selected for development and commercialization pursuant to this Section 2.12, but thereafter such YAMANOUCHI Preclinical Compound or the corresponding YAMANOUCHI Clinical Compound or a Product based thereon is the subject of an Abandonment Notice by a Party and the rights of the other Party to select such YAMANOUCHI Preclinical Compound for development and commercialization pursuant to this Section 2.12 shall have expired, all rights thereto shall revert to YAMANOUCHI; provided that YAMANOUCHI shall not in any case utilize a YAMANOUCHI Compound to develop any product based thereon outside the Field if such YAMANOUCHI Compound’s primary mechanism of action is to modulate a Target against which such YAMANOUCHI Compound was identified as having activity in the Research Program. Notwithstanding the foregoing provisions of this Section 2.12(f), if within five years after the end of the Research Program, YAMANOUCHI shall commence development or commercialization of a YAMANOUCHI Compound in the Field as to which rights have reverted to YAMANOUCHI pursuant to this Section 2.12(f) and the primary mechanism of action of such YAMANOUCHI Compound is to modulate a Target against which such YAMANOUCHI Compound was identified as having activity in the Research Program or thereafter during the Exclusivity Period, YAMANOUCHI shall be required to pay milestones to ICAgen with respect to such YAMANOUCHI Compound as provided in Section 6.2 (treating such YAMANOUCHI

Compound as a Preclinical Compound for purposes of Section 6.2(a) and a Clinical Compound for purposes of Sections 6.2(b) and (c)) and royalties as provided in Section 6.3(a) (treating such YAMANOUCHI Compound as a Product for purposes of Section 6.3(a)).

(g) ICAgen Reversion of Rights. Subject to the provisions of Section 2.9, (i) if an ICAgen Compound, an ICAgen Selected Hit Compound, an ICAgen Pre-lead Compound, an ICAgen Lead Compound or an ICAgen Advanced Lead Compound is not selected as an ICAgen Selected Hit Compound, an ICAgen Pre-lead Compound, an ICAgen Lead Compound, an ICAgen Advanced Lead Compound or an ICAgen Preclinical Compound, respectively, all rights thereto shall revert solely to ICAgen; (ii) if an Analog synthesized by ICAgen under the Research Program is not selected as an ICAgen Lead Compound or an ICAgen Advanced Lead Compound, all rights thereto shall revert to ICAgen; (iii) if an ICAgen Preclinical Compound is not selected for development and commercialization by either Party pursuant to this Section 2.12, all rights thereto shall revert to ICAgen; and (iv) if an ICAgen Preclinical Compound has been selected for development and commercialization pursuant to this Section 2.12, but thereafter such ICAgen Preclinical Compound or the corresponding ICAgen Clinical Compound or a Product based thereon is the subject of an Abandonment Notice by a Party and the rights of the other Party to select such ICAgen Preclinical Compound for development and commercialization pursuant to this Section 2.12 shall have expired, all rights thereto shall revert to ICAgen. Notwithstanding the foregoing provisions of this Section 2.12(g), if within five years after the end of the Research Program, ICAgen shall commence development or commercialization of an ICAgen Compound in the Field as to which rights have reverted to ICAgen pursuant to this Section 2.12(g) and the primary mechanism of action of such ICAgen Compound is to modulate a Target against which such ICAgen Compound was identified as having activity in the Research Program or thereafter during

the Exclusivity Period, ICAgen shall be required to pay YAMANOUCHI royalties as provided in Section 6.3(b) (treating such ICAgen Compound as a Product for purposes of Section 6.3(b)).

(h) Effect of Abandonment. With respect to a Clinical Compound or Product based thereon that is the subject of an Abandonment Notice by a Party, (i) the abandoning Party shall promptly return to the other Party all relevant records and materials in its possession or control containing the other Party’s Confidential Information and to which the abandoning Party does not retain any rights or licenses hereunder; (ii) all licenses granted by the other Party to the abandoning Party under Section 5 shall terminate; and (iii) if the other Party holds unexpired rights to elect to develop or commercialize such Clinical Compound or Product based thereon under this Section 2.12 or is the Party to whom such Preclinical Compound, Clinical Compound or Product based thereon reverts as provided in Sections 2.12(f) or (g), (x) the abandoning Party shall transmit to the other Party all reports, information and data relating to such Clinical Compound or Product based thereon obtained or developed by the abandoning Party pursuant to this Agreement within [**] after the date of such Abandonment Notice, (y) all INDs, NDAs and other regulatory filings made or filed for such Clinical Compound or Product based thereon shall be transferred by the abandoning Party to the other Party if the other Party so desires and, for up to [**] after the abandoning Party transmits the reports, information and data relating to such Clinical Compound or Product based thereon to the other Party, the abandoning Party shall, at its cost, maintain such INDs, NDAs and other regulatory filings while the other Party tries to decide whether to develop and commercialize such Clinical Compound and Products based thereon pursuant to Section 2.12(a) or (b), and (z) the abandoning Party shall use reasonable efforts to cooperate with the other Party at the other Party’s expense to maintain the regulatory filings transferred to the other Party for an additional period not to exceed [**]that the other Party may request, but only for so long as the

other Party provides assurances reasonably satisfactory to the abandoning Party that the other Party is actively developing or commercializing such Clinical Compound or Product based thereon or diligently performing reviews of the data and information on such Clinical Compound and Product based thereon to determine whether to elect to develop and commercialize such Clinical Compound and Product based thereon.

(i) Limitation on YAMANOUCHI Right to Elect. Notwithstanding the foregoing provisions of this Section 2.12, YAMANOUCHI may not elect to develop and commercialize any ICAgen Compound other than ICAgen Exclusive Compounds if, prior to 45 days after the time such ICAgen Compound is designated as a Selected Hit Compound pursuant to Section 3.2(b), ICAgen provides notice to YAMANOUCHI (a “Rejection Notice”) that such ICAgen Compound is the subject of an internal ICAgen development program or is encumbered by rights of one or more Third Parties that preclude ICAgen from permitting YAMANOUCHI to develop and commercialize such ICAgen Compound as provided in this Agreement or that require ICAgen to make payments to such Third Party or Parties in respect of the development or commercialization of such ICAgen Compound by YAMANOUCHI. If ICAgen timely gives a Rejection Notice as to an ICAgen Compound, YAMANOUCHI’s election to develop and commercialize such ICAgen Compound pursuant to this Section 2.12 shall be void and of no force or effect (and no license shall be deemed to have been granted to YAMANOUCHI as to such ICAgen Compound pursuant to Section 5.2(a)).

(j) Selection of Back-up Compounds. If either Party has elected to develop and commercialize a Preclinical Compound in the Primary Field or in the Secondary Field under Section 2.12(a) or 2.12(b) for one or more indications, then such Party shall have the right, during the [**] period following such election, to select [**] back-up compounds (which shall be selected

from any available Selected Hit Compounds, Pre-lead Compounds, Lead Compounds, Advanced Lead Compounds or Preclinical Compounds) (“Back-up Compounds”) in such Field for one or more of the same indications. The Parties shall endeavor to make their elections and selections as promptly as reasonably practicable so as not to unnecessarily delay one another in making their elections and selections. The Party selecting a Back-up Compound shall have exclusive rights to such Back-up Compound to the same extent such Party has exclusive rights to the elected Preclinical Compound, for so long as such Party continues to develop and commercialize the elected Preclinical Compound in the applicable Field, for the applicable indication or indications and in the applicable Territory. A selected Back-up Compound shall thereafter be available to the Party selecting it to elect for commercialization and development under Section 2.12(a) or 2.12(b). The Party selecting a Back-up Compound shall not have the obligation to develop or commercialize the Back-up Compound for so long as it is developing and commercializing the elected Preclinical Compound in the applicable Field, for the applicable indication or indications and in the applicable Territory. If a Party elects to develop and commercialize a Back-up Compound in the place of a Preclinical Compound for which it has given an abandonment notice, then such Party shall be entitled to select a new Back-up Compound to replace the Back-up Compound elected for development and commercialization. In addition, with respect to each Preclinical Compound which either Party has elected to develop and commercialize under Section 2.12 (a) or (b), such Party shall have a [**] right to replace one of the Back-up Compounds selected by such Party for such Preclinical Compound with a different Back-up Compound. If a milestone payment under Section 6.2(b) or Section 6.2(c) has been paid by YAMANOUCHI with respect to a Preclinical Compound that is abandoned by YAMANOUCHI and YAMANOUCHI subsequently elects to develop and commercialize one of its Back-up Compounds in the applicable Field, for the

same primary indication and in the applicable Territory, then such milestone payment shall not be payable by YAMANOUCHI with respect to such Back-up Compound.

3.	PROJECT COMMITTEE AND JOINT RESEARCH COMMITTEE.

3.1 Members. The Parties shall establish a research committee (the “Project Committee”) and a steering committee (the “Joint Research Committee”), each of which shall be comprised of an equal number of members designated by each Party. The Project Committee and the Joint Research Committee shall be established as soon as possible after the Effective Date. The initial members of the Joint Research Committee are set forth on Exhibit B. Any member of the Project Committee or the Joint Research Committee may be represented at any meeting by a designee appointed by such member for such meeting. Each Party shall be free to change its representative members, upon notice to the other Party.

3.2 Responsibilities of the Project Committee. The Project Committee shall be responsible for overseeing the Research Program, including without limitation:

(a) to evaluate and determine scientific criteria to be implemented under the Research Program;

(b) to evaluate data from the Research Program, designate Selected Hit Compounds and Advanced Lead Compounds for further research, determine whether target validation has been completed in accordance with the Annual Research Plan, recommend to the Joint Research Committee which Selected Hit Compounds and Pre-lead Compounds should be designated Pre-lead Compounds and Lead Compounds, recommend to the Joint Research Committee which Advanced Lead Compounds should be designated Preclinical Compounds for selection by the Parties for development and commercialization as provided in Section 2.12, and evaluate and recommend to the Joint Research Committee the accomplishment of concept

validation and other milestone components (including achievement of the First, Second and Third Target Milestones) set forth in the Annual Research Plan;

(c) to review and evaluate progress under the Research Program, and make appropriate recommendations relating thereto to the Joint Research Committee, provided that neither the Project Committee nor the Joint Research Committee shall have the authority to make any determination that either Party is in breach of its obligations under the Research Program;

(d) to provide for the exchange of information relating to the Research Program; and

(e) to coordinate and monitor publication of research results arising from the Research Program, subject to the provisions of Section 12.1.

3.3 Responsibilities of the Joint Research Committee. The Joint Research Committee shall be responsible for making decisions in relation to the Research Program, including without limitation:

(a) to designate Pre-lead Compounds and Lead Compounds for further research and Preclinical Compounds for selection by the Parties for development and commercialization as provided in Section 2.12; and

(b) to determine the accomplishment of concept validation and other milestone components (including achievement of the First, Second and Third Target Milestones) set forth in the Annual Research Plan. No ICAgen Compound or YAMANOUCHI Compound may be designated by the Joint Research Committee as a Lead Compound after the end of the Research Program or as a Preclinical Compound more than [**] after the end of the Research Program. If an ICAgen Compound or a YAMANOUCHI Compound is designated by the Joint Research Committee as a Preclinical Compound after the end of the Research Program, then the Clinical

Compound Selection Period provided in Section 2.12 shall, with respect to such Preclinical Compound, be extended for a period of time (not to exceed [**]) equal in duration to the period of time from the end of the Research Program to such designation by the Joint Research Committee.

3.4 Meetings. Meetings of the Project Committee shall be held from time to time as necessary, but no less frequently than once every two months, on such dates and at such times as the Parties may agree. During each calendar year, the Project Committee shall meet on two (2) occasions in person, with such meetings alternating between the Parties’ respective research locations. Other meetings of the Project Committee shall be held by videoconference or otherwise as the Parties may agree. Either Party may, as it deems appropriate, have researchers or others employed by it attend Project Committee meetings in a non-voting capacity. A meeting agenda and other written materials to be discussed during each Project Committee meeting shall be distributed to members in advance, as agreed by the Parties from time to time.

3.5 Decisions.

(a) Project Committee. All decisions of the Project Committee shall be made by unanimous agreement of the members (or their designees) present in person, by videoconference or otherwise as the Parties may agree at any meeting, provided that at least two representatives of each Party are present at such meeting.

(b) Joint Research Committee. Each decision of the Joint Research Committee shall be made when the signatures of all the members of the Joint Research Committee are obtained on the written action evidencing such decision.

(c) Disagreements. In the event that unanimity cannot be reached by the Joint Research Committee with respect to a matter that is subject to its decision-making authority, then the matter shall be referred for further review and resolution to the Director of Institute for Drug

Discovery Research, or such other similar position designated by YAMANOUCHI from time to time, and the President of ICAgen, or such other officer designated by ICAgen from time to time. The designated officers of each Party shall use reasonable efforts to resolve the matter within 30 days after the matter is referred to them. If they cannot resolve the matter within 30 days, then, to the extent that the unresolved matter relates to the designation of a Preclinical Compound for which milestone payments would be owed under Section 6.2(a) or to the determination of whether the First, Second and Third Target Milestones have been achieved, YAMANOUCHI shall have the right to make the final decision on such matter, provided that if YAMANOUCHI decides not to designate any Preclinical Compound during the Clinical Compound Selection Period or YAMANOUCHI decides that the First or Second Target Milestone has not been achieved because a Pre-lead Compound or Lead Compound, respectively, has not been identified, and ICAgen disagrees with such decision, and thereafter YAMANOUCHI does not make a payment under Section 6.2(a) that it would otherwise be required to make or YAMANOUCHI requires ICAgen to make available a list of additional Targets pursuant to Section 2.4(b), then ICAgen shall thereafter have the right to develop the respective Advanced Lead Compound, Selected Hit Compound or Pre-Lead Compound, and to commercialize Products based thereon, subject to the royalty provisions of Section 6.3(b) (treating such compound as a Product for such purpose). In all other cases, the matter shall be decided in accordance with the dispute resolution procedures described in Section 15.14.

3.6 Minutes. Within 15 days after each Project Committee meeting, one Party shall prepare draft minutes of the meeting as agreed by the Parties, which draft minutes shall provide a description in reasonable detail of the discussions had at the meeting and a list of any actions, decisions or determinations approved by the Project Committee. The other Party shall edit the

draft minutes within 15 days after receipt from the Party preparing the draft minutes. The final draft form of the minutes shall be circulated by the preparing Party to all members of the Project Committee sufficiently in advance of the next meeting to allow adequate review and comment prior to the next meeting. Minutes shall be approved or disapproved, and revised as necessary, at the next meeting. Final minutes shall be distributed by the preparing Party to the members of the Project Committee as well as to members of the Joint Research Committee.

(b) any warranty claims, Product recalls or any tort claims of personal injury (including death) or property damage relating to or arising out of the manufacture, use, distribution or sale of any Clinical Compound or Product by ICAgen, its Affiliates or its Sublicensees and their respective directors, officers, employees and agents, except to the extent such liabilities, damages, losses, costs or expenses arise out of or result from the causes set forth in Section 11.1(a); or

11.3 Notice. In the event that either Party is seeking indemnification under Section 11.1 or Section 11.2 in respect of a claim by a Third Party, such Party shall inform the indemnifying Party of the claim as soon as reasonably practicable after it receives notice of the claim, shall

permit the indemnifying Party to assume direction and control of the defense of the claim (including the sole right to settle it at the sole discretion of the indemnifying Party, provided that such settlement does not impose any obligation on the indemnified Party), and shall cooperate as reasonably requested (at the expense of the indemnifying Party) in the defense of the claim.

12.	PUBLICATION; CONFIDENTIALITY.

12.1 Publication.

(a) Both Parties recognize that the other Party may wish to publish the results of their work relating to the Research Program. However, both Parties also recognize the importance of acquiring patent protection on inventions prior to publication. Consequently, each Party shall provide to the Project Committee (or after the Project Committee disbands, the other Party) the opportunity to review any proposed abstracts, manuscripts, other publications or summaries of presentations which cover the results of the Research Program or the pre-clinical or clinical development of any Clinical Compound. The Project Committee (or other Party) shall respond in writing promptly and in no event later than 30 days after its receipt of the proposed material with either approval of the proposed material or a specific statement of concern, based upon either the need to seek patent protection or disclosure of technical or scientific Confidential Information in breach of Section 12.2. In the event of concern, the submitting Party agrees not to submit such publication or to make such presentation that contains information as to which the Project Committee (or other Party) has expressed concern until the Project Committee (or other Party) is given a reasonable period of time (not to exceed 60 days) to seek patent protection for any material in such publication or presentation which it believes is patentable or to resolve any other issues.

(b) Both Parties understand that publications containing chemical structures under development shall not be approved unless the following conditions are fulfilled: (x) at least

[**] has passed since the applicable patent application has been laid open or has otherwise become known to the public other than through a breach of the provisions of this Agreement by the Party seeking to publish, and (y) the chemical modifications to the basic skeleton of the chemical structures for which the patent application referred to in clause (x) above was filed have been completed.

(c) In any publication permitted under this Section 12.1, each Party shall acknowledge its collaboration with the other Party under this Agreement.

(d) Nothing in Section 12 shall prevent ICAgen: (i) in connection with efforts to secure financing at any time during the term of this Agreement, from issuing statements as to achievements made, and the status of the work being done by the Parties, under this Agreement, so long as such statements do not jeopardize the ability to obtain patent protection on Inventions or disclose nonpublic technical or scientific Confidential Information; or (ii) from issuing statements that ICAgen determines to be necessary to comply with applicable law (including the disclosure requirements of the U.S. Securities and Exchange Commission, Nasdaq or any other stock exchange on which securities issued by ICAgen are traded); provided that, to the extent practicable under the circumstances, ICAgen shall provide YAMANOUCHI with a copy of the proposed text of any statement involving YAMANOUCHI sufficiently in advance of the scheduled release thereof to afford YAMANOUCHI a reasonable opportunity to review and comment upon the proposed text and ICAgen shall in good faith consider and give due respect to any comments from YAMANOUCHI.

(e) Sections 12.1(a) and (c) shall cease to be applicable to any Clinical Compound upon commercial launch of a Product based thereon, provided, however, that any information related to a new therapeutic use of the Clinical Compound and/or Products based thereon shall continue to be governed by the provisions of Section 12.1(a) hereof.

12.2 Confidentiality; Exceptions. Except to the extent expressly authorized by this Agreement (including without limitation Section 12.1) or otherwise agreed in writing, the Parties agree that, for the term of the Research Program and for ten years thereafter the receiving Party, its Affiliates and its Sublicensees, if any, (x) shall use their reasonable best efforts to keep, and to ensure that their officers and directors and agents keep, confidential and (y) shall not use for any purpose other than in the conduct of the Research Program (except that each Party may use without restriction information developed by such Party in the Research Program that is of general utility outside the Research Program) both the financial terms of this Agreement and any information furnished to it by the other Party, its Affiliates or its Sublicensees or developed under or in connection with the Research Program, except to the extent that it can be established by the receiving Party by competent proof that such information: (i) is or hereafter becomes generally available to the public other than by reason of any default by the receiving Party with respect to its confidentiality obligations hereunder; (ii) was already known to the recipient as evidenced by prior written documents in its possession; (iii) is disclosed to the recipient by a Third Party who is not in default of any confidentiality obligation to the disclosing Party; or (iv) is independently developed by or for the receiving Party without reference to or reliance upon the information furnished by the other Party (“Confidential Information”).

12.3 Exclusions to Confidentiality. The restrictions contained in Section 12.2 shall not apply to Confidential Information that (i) is submitted by the recipient to governmental authorities to facilitate the issuance of marketing approvals for a Product, provided that reasonable measures shall be taken to assure confidential treatment of such information, if practicable; (ii) is provided by the recipient to Third Parties under appropriate terms and conditions, including confidentiality

provisions equivalent to those in this Agreement, for consulting, manufacturing development, manufacturing, external testing, marketing trials and sublicensing or potential sublicensing; (iii) is contained in any report submitted to any licensor(s) of technology or compositions of matter that are employed in the Research Program, provided that the licensor is subject to a customary confidentiality obligation as to proprietary information and trade secrets; or (iv) is otherwise required to be disclosed in compliance with applicable laws or regulations (including, without limitation, to comply with SEC, Nasdaq or stock exchange disclosure requirements) or order by a court or other regulatory body having competent jurisdiction; provided that if a Party is required to make any such disclosure of the other Party’s Confidential Information it will, except where impracticable for necessary disclosures, for example to physicians conducting studies or to health authorities, give reasonable advance notice to the other Party of such disclosure requirement and, except to the extent inappropriate in the case of patent applications or otherwise, will use its reasonable best efforts to secure confidential treatment of such Confidential Information required to be disclosed.

12.4 Injunctive Relief. The Parties acknowledge that money damages alone would not adequately compensate the disclosing Party in the event of a breach by the receiving Party of this Section 12, and that, in addition to all other remedies available to the disclosing Party at law or in equity, it shall be entitled to injunctive relief for the enforcement of its rights under this Section 12.

13.	TERM; TERMINATION.

13.1 Term. This Agreement shall commence as of the Effective Date and, unless sooner terminated as provided hereunder, shall expire as follows:

(a) As to each Product in each country in the applicable Territory, this Agreement shall expire upon the expiration of the Royalty Term with respect to such Product in such country.

(b) This Agreement shall expire in its entirety upon the termination of the Royalty Term with respect to all Products in all countries in all Territories.

Notwithstanding the foregoing, in no event shall this Agreement expire prior to the last to occur of (x) the date that is 12 months after the end of the term of the Research Program, (y) the last date on which a Party has the right to elect to develop and commercialize a Preclinical Compound or Clinical Compound or Product based thereon pursuant to Section 2.12, or (z) the date on which no Party is developing or commercializing a Preclinical Compound or Clinical Compound or Product based thereon pursuant to Section 2.12.

13.2 Breach.

(a) Subject to Section 13.2(e), the failure by either Party to comply with any of its material obligations contained in this Agreement shall entitle the other Party to give to the Party in default notice specifying the nature of the default and requiring it to cure such default. If such default is not cured within 60 days (30 days in the event of a default with respect to an obligation to pay money) after the receipt of such notice (or, if such default cannot be cured within such 60-day period, if the Party in default does not commence and diligently continue actions to cure such default, the Parties agreeing that all defaults with respect to obligations to pay money shall be curable within the 30-day period provided above), the notifying Party shall be entitled, without

prejudice to any of its other rights conferred on it by this Agreement, and in addition to any other remedies available to it by law or in equity, to terminate this Agreement in its entirety, by giving written notice to take effect immediately upon delivery of such notice. The right of either Party to terminate this Agreement, as provided in this Section 13.2(a), shall not be affected in any way by its waiver or failure to take action with respect to any previous default.

(b) The failure of a representation or warranty made under this Agreement by either Party to be true in all material respects as of the date made and the inaccuracy of which materially adversely affects the rights of the other Party under this Agreement shall entitle the other Party, without prejudice to any of its other rights conferred on it by this Agreement, and in addition to any other remedies available to it by law or in equity, to terminate this Agreement in its entirety, by giving written notice to take effect immediately upon delivery of such notice. The right of either Party to terminate this Agreement, as provided in this Section 13.2(b), shall not be affected in any way by its waiver or failure to take action with respect to any previous default.

(c) Any dispute concerning whether a Party is in default under the terms of this Agreement shall be referred for arbitration pursuant to Section 15.14. The effectiveness of any notice given pursuant to Section 13.2(a) or 13.2(b) shall be tolled during the pendency of any such arbitration.

(d) An election of remedy by a Party for a material breach of this Agreement under this Section 13.2 on one occasion shall not constitute a waiver as to any other remedy that may be available to such Party under this Section 13.2 as to any material breach on another occasion.

(e) With respect to breaches by a Party of its obligations set forth in Section 4.1(a) or (b) to develop and commercialize Clinical Compounds and Products based thereon, the

sole remedy of the other Party (in addition to any rights that it may obtain under Section 2.12) shall be to terminate the license under Section 5 relating to the applicable Clinical Compounds and Products based thereon.

13.3 Termination Other Than for Breach. YAMANOUCHI shall have the right to terminate this Agreement as specified in Section 2.4(c).

13.4 Effect of Expiration or Termination.

(a) Following expiration of the term of this Agreement with respect to a Product in a country in the applicable Territory pursuant to Section 13.1(a), the licensee Party under this Agreement shall have the royalty-free, perpetual right to continue to manufacture, have manufactured, use and sell such Product in such country. Following expiration of the term of this Agreement in its entirety pursuant to Section 13.1(b), the licensee Party shall have the royalty-free, perpetual right to continue to manufacture, have manufactured, use and sell all Products previously licensed by it in all countries in the applicable Territory.

(b) Upon termination of this Agreement by YAMANOUCHI pursuant to Section 13.2: (i) ICAgen shall promptly transfer to YAMANOUCHI copies of all data, reports, records and materials in ICAgen’s possession or control which relate to the Research Program, return to YAMANOUCHI all relevant records and materials in ICAgen’s possession or control containing Confidential Information of YAMANOUCHI to which ICAgen does not retain rights hereunder and furnish to YAMANOUCHI all Substances provided to ICAgen by YAMANOUCHI in connection with the Research Program; (ii) all licenses granted by YAMANOUCHI to ICAgen under Section 5 shall terminate; (iii) ICAgen shall be deemed to have given an ICAgen Abandonment Notice as to all Clinical Compounds and Products based thereon then being developed or commercialized by ICAgen; and (iv) the exclusivity granted to YAMANOUCHI

pursuant to Section 2.8 shall continue during the remainder of the Exclusivity Period, if any. The licenses granted to YAMANOUCHI by ICAgen pursuant to Section 5 shall continue in full force and effect, subject to YAMANOUCHI’s obligations under this Agreement, including payment of royalties and milestones, as provided in Sections 5, 6, and 7.

(c) Upon termination of this Agreement by ICAgen pursuant to Section 13.2: (i) YAMANOUCHI shall promptly transfer to ICAgen copies of all data, reports, records and materials in YAMANOUCHI’s possession or control which relate to the Research Program, return to ICAgen all relevant records and materials in YAMANOUCHI’s possession or control containing Confidential Information of ICAgen to which YAMANOUCHI does not retain rights hereunder and furnish to ICAgen all Substances provided to YAMANOUCHI by ICAgen in connection with the Research Program; (ii) all licenses granted by ICAgen to YAMANOUCHI under Section 5 shall terminate; (iii) YAMANOUCHI shall be deemed to have given a YAMANOUCHI Abandonment Notice as to all Clinical Compounds and Products based thereon then being developed or commercialized by YAMANOUCHI; and (iv) the exclusivity granted to YAMANOUCHI pursuant to Section 2.8 shall terminate. The licenses granted to ICAgen by YAMANOUCHI pursuant to Section 5 shall continue in full force and effect, subject to ICAgen’s obligations under this Agreement, including payment of royalties, as provided in Sections 5, 6, and 7.

(d) Upon termination of this Agreement by YAMANOUCHI pursuant to Section 13.3, all rights to YAMANOUCHI Compounds shall revert to YAMANOUCHI and all rights to ICAgen Compounds shall revert to ICAgen, unless and to the extent otherwise provided in Section 2.9 above.

(e) In the event of the termination of any license rights granted to either Party as provided in Section 13.4(b) or (c), the other Party shall recognize the sublicenses previously granted hereunder to such Party’s Sublicensees; provided, however, that the other Party shall not assume, and shall not be responsible to any such Sublicensee for, any representations, warranties or obligations of the Party that granted the sublicense to any Sublicensee.

13.5 Accrued Rights, Surviving Obligations.

(a) Termination, relinquishment or expiration of this Agreement for any reason shall be without prejudice to any rights which shall have accrued to the benefit of either Party prior to such termination, relinquishment or expiration. Such termination, relinquishment or expiration shall not relieve either Party from obligations which are expressly indicated to survive termination or expiration of this Agreement.

(b) Termination, relinquishment or expiration of this Agreement shall not terminate each Party’s obligation to pay all research funding, royalties, milestones and other payments that shall have accrued prior to such termination. All of the Parties’ rights and obligations under Sections 2.7, 2.8 (subject to Section 13.4(c)), 2.9, 2.10, 2.11(b), 2.12, 4, 5 (to the extent provided in Section 13.4(b) and (c)), 7, 8, 9, 10, 11, 12, 13.4, 13.5, and 15 shall survive termination, relinquishment or expiration hereof.

14. FORCE MAJEURE.

Neither Party shall be held liable or responsible to the other Party nor be deemed to be in default under or in breach of any provision of this Agreement for failure or delay in fulfilling or performing any obligation of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For purposes of this Agreement, force majeure is defined as causes beyond the control of the Party, including, without limitation, acts of God; acts, regulations or laws of any government; war; civil commotion;

destruction of production facilities or materials essential to fulfilling or performing such Party’s obligations by fire, flood, earthquake, explosion or storm; labor disturbances; epidemic; and failure of pubic utilities or common carriers. In such event YAMANOUCHI or ICAgen, as the case may be, shall immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice shall thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled and for thirty (30) days thereafter. To the extent possible, each Party shall use reasonable efforts to minimize the duration of any force majeure.

15. MISCELLANEOUS.

15.1 Non-solicitation. During the term of the Research Program and for a period of one year thereafter, neither Party shall solicit, induce, encourage or attempt to induce or encourage any employee of the other Party to terminate his or her employment with such other Party or to breach any other obligation to such other Party.

15.2 Relationship of Parties. Nothing in this Agreement is intended or shall be deemed to constitute a partnership, agency, employer-employee or joint venture relationship between the Parties. No Party shall incur any debts or make any commitments for the other, except to the extent, if at all, specifically provided herein.

15.3 Assignment. Neither Party shall be entitled to assign its rights hereunder without the express written consent of the other Party hereto, except that both YAMANOUCHI and ICAgen may otherwise assign their respective rights and transfer their respective duties hereunder to any assignee of all or substantially all of their respective businesses (or that portion thereof to which this Agreement relates) or in the event of their respective merger or consolidation or similar transaction. No assignment and transfer shall be valid or effective unless and until the assignee/transferee shall agree in writing to be bound by the provisions of this Agreement.

15.4 Disclaimer of Warranties. THE PARTIES EXPRESSLY DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT OF THIRD PARTY RIGHTS, UNLESS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT.
