The books and records of CURAGEN, its Affiliates or its Sublicensees, as the case may be, shall be maintained in accordance with the generally accepted accounting principles, consistently applied, and with sufficient particulars as necessary to determine such deductions and amounts.

In the event that CURAGEN, its Affiliates, or Sublicensees intend to sell a Combination Product, the Parties shall meet approximately one (1) year prior to the anticipated Launch of such Combination Product to negotiate in good faith and agree to an appropriate adjustment to Net Sales to reflect the relative significance and value of the Covered Product and the other pharmaceutically active agent(s) contained in the Combination Product on a country-by-country basis. If there is a stand alone Covered Product on the market in a given country which corresponds to the HDAC Inhibitor within the Combination Product, the adjustment to Net Sales for such country shall equal the Net Sales of the Combination Product multiplied by a fraction, the numerator of which is the current price of the Covered Product and the denominator of which is the reasonable fair market value, in the aggregate, of all pharmaceutically active agents contained in the Combination Product in each case in the same country as the country in which the Combination Product is to be sold. If no such Covered Product is on the market in a given country, and if, after good faith negotiations (not to exceed ninety (90) days), the Parties cannot agree to an appropriate adjustment, Net Sales for such country shall equal Net Sales of the Combination Product multiplied by a fraction, the numerator of which is the reasonable fair market value of the Product and the denominator of which is the reasonable fair market value, in the aggregate, of all pharmaceutically active agents contained in the Combination Product. If the Parties cannot agree on the “fair market value” of either the Product or any of the pharmaceutically active agents, the Parties shall retain a panel of three valuation experts to make such a determination, the costs for which shall be shared equally by the Parties. Each Party shall select one expert, who shall not be an employee of either and who shall have at least at least a university degree in economics and five (5) years experience in conducting such valuations. The two experts shall promptly select a mutually agreeable third expert with like qualifications. The experts shall render a written opinion binding on the Parties for the relevant countries within thirty (30) days, which shall be binding, with no right of appeal, on both Parties and any Affiliates and Sublicensees.

Notwithstanding the foregoing, in connection with (X) any sale or other disposition of Covered Product that is not a bona fide, arms length transaction for money, or (Y) any other use of Covered Product that does not result in or give rise to sales revenue that is customary in the

country in which such use takes place (except as provided in the next paragraph), Net Sales shall be calculated at the relevant open market price in the country in which such sale, disposition or use takes place, or, if such price is not reasonably ascertainable, at a reasonable price, assessed on an arms length basis, for the goods and/or services received in consideration of the sale, disposition or use of Covered Product.

CURAGEN’s or any of its Affiliate’s transfer of Covered Product to another Affiliate or a Sublicensee shall not result in any Net Sales, unless such Covered Product is consumed by such Affiliate or Sublicensee in the course of its commercial activities. In such case, Net Sales shall occur upon such other Affiliate’s or Sublicensee’s sale of such Covered Product to a Third Party. Further, the disposition of Covered Product for, or the use of Covered Product in, pre-clinical or clinical (Phase I – III) trials or other market-focused (Phase IV or V) trials or free samples shall not result in any Net Sales, unless CURAGEN, its Affiliate or Sublicensee is permitted to receive payment for Covered Product used in clinical trials which includes a reasonable profit.

1.33 “Phase II” shall mean within oncology, one or more trials with enough patients (usually 20 patients or more) in at least one treatment arm designed to determine a reasonable

estimate of response rate (usually a confidence interval narrow enough to be acceptable as evidence of activity versus active or historical control data). For other indications, one or more randomized controlled trials of sufficient size to determine with 80% power an a priori agreed upon clinical effect.

1.34 “Phase III” shall mean one or more pivotal trials designed and powered for registration with FDA. Agreement from the FDA on study design must be obtained before Phase III initiation in a pre-Phase III meeting or through FDA’s Special Protocol Assessment Procedures.

1.35 “Phase II Initiation” shall mean the day when the first patient in the first Phase II clinical trial of the relevant Collaboration Product, which trial has been approved by the Joint Steering Committee, gets dosed. If the trial is a Phase I/II trial, the Initiation of Phase II refers to the day when the first patient in the treatment arm designed to determine a reasonable estimate of response rate gets dosed.

1.36 “Phase III Initiation” shall mean the day when the first patient in the first Phase III clinical trial of the relevant Collaboration Product, which trial has been approved by the Joint Steering Committee, gets dosed.

(b) Without limiting the generality of Section 3.4(a), during the Research Term, (i) TOPOTARGET agrees that it shall not, itself or through another party, perform research for, collaborate with or grant licenses to any Third Party with respect to any HDAC Inhibitor for use in the Field within the Territory, and will not, itself or through another party, undertake such activities with respect to any HDAC Inhibitor for use in the Field within the Territory for the benefit of any Third Party, except in connection with the Third Party Agreements described in Section 3.1 hereof or as otherwise expressly permitted herein in Section 3.3, and (ii) TOPOTARGET shall be permitted, itself and/or with one or more other parties, to perform research for, collaborate with and/or grant licenses to any Third Party with respect to any HDAC Inhibitor for development, sale and/or use solely within the TOPOTARGET Territory, subject only to the provisions of Section 3.5 hereof and to the provisions of Section 8.4 hereof.

(c) Following the Research Term. TOPOTARGET agrees that, following the Research Term, it shall not, itself or through another party, for the benefit of TOPOTARGET or any Third Party, perform research for, collaborate with or grant licenses to any Third Party with respect to any Collaboration Product for use in the Territory, or perform clinical development anywhere in the world with respect to, or market or sell any HDAC Inhibitor in a therapeutic indication (e.g., lung cancer) within the Territory, for which, at the time of the commencement of any such research, collaboration, license grant, clinical development, marketing or selling, any

Collaboration Product is being marketed or developed, or is planned for development based on demonstrated efficacy in a relevant animal model of a disease (“CURAGEN Indications”) for use in the Territory in the Field and such Collaboration Product continues to be diligently developed in that indication by CURAGEN. CURAGEN shall regularly advise TOPOTARGET of such development and planning for development, and TOPOTARGET shall notify CURAGEN of any intent to exercise its rights hereunder within the Territory and provide CURAGEN with [******(*****)] business days in which to update any such information as to which indications are currently in development or planned for development based on demonstrated efficacy in a relevant animal model of a disease. In the event that any such prohibited clinical development of a TOPOTARGET HDAC Inhibitor is conducted by an independent Third Party which leads to the use of any such HDAC Inhibitor in a CURAGEN Indication in competition with actual sales of a Collaboration Product that has been developed specifically for that indication, the Parties shall agree in good faith on appropriate compensation to CURAGEN [***************************************************************]; PROVIDED THAT such compensation shall not exceed the lesser of (i) [****************** *********************************] or (ii) [***********************************]. In the event that the parties cannot agree on appropriate compensation after ninety (90) days of good faith negotiations, the parties shall refer the matter to an independent expert agreed upon by the parties, who will set such compensation at an amount not to exceed the lesser of (i) and (ii) above. The decision of the expert shall be binding on the parties, and any compensation provided to CURAGEN pursuant to this Section 3.4(c) shall be CURAGEN’s exclusive remedy and TOPOTARGET’s sole obligation and liability with respect to any independent Third Party clinical development as described herein.

(d) The Parties hereby agree that, during the Research Term, CURAGEN shall not be permitted to license an HDAC Inhibitor or acquire a Third Party with an HDAC Inhibitor program and CURAGEN shall prohibit its Affiliates from licensing HDAC Inhibitors from Third Parties or acquiring a Third Party with an HDAC Inhibitor program as provided above. Notwithstanding the foregoing, in the event that CURAGEN is acquired by a Third Party which has an HDAC Inhibitor program, such transaction shall not be precluded by this Section 3.4

and, subject to compliance with Sections 7.2(f), 8.2(a) and Article 12, CURAGEN shall be free to develop and commercialize any HDAC Inhibitors arising from such Third Party’s program alone or in conjunction with such Third Party following any such transaction.

(e) TOPOTARGET’s activities with respect to HDAC Inhibitors which are not Collaboration Products shall not be limited except as expressly provided in this section. Nothing in this Section 3.4 shall in any way be deemed to affect the scope of any licenses or rights expressly granted to CURAGEN pursuant to Section 7 below, or the Parties’ obligations pursuant to Section 8 or Section 12 below.

3.5 Licensing by TOPOTARGET within the TOPOTARGET Territory; CURAGEN’s Right of First Negotiation.

(a) In the event that TOPOTARGET wishes to grant any Third Party licenses or rights in any country within the TOPOTARGET Territory with respect to the development, marketing or distribution of a Collaboration Product (regardless of whether TOPOTARGET or such Third Party initiated discussions of such sublicensing), it may do so during the Research Term only after such Collaboration Product has completed Phase II clinical studies and after the Research Term it may do so at any development stage. In any event, before making or accepting any such Third Party offer, as the case may be, TOPOTARGET shall first propose to grant such rights to CURAGEN. Such proposal shall be in writing, be made in good faith, and set forth terms no less favorable to CURAGEN than those to be offered to, or offered by, such Third Party. Within [********] days after receipt of any such proposal, CURAGEN shall notify TOPOTARGET as to whether CURAGEN wishes to enter into negotiations for such rights. If CURAGEN provides timely notice that it wishes to do so, then the Parties shall conduct exclusive negotiations and use good faith efforts to conclude an agreement within [********] days thereafter. If the Parties are unable to agree upon the terms of such agreement despite the use of good faith efforts for a period of at least [********] days, CURAGEN shall put its proposal in writing (the “Last Offer”). Thereafter, TOPOTARGET shall be free to grant a license or other rights to Third Parties to the rights described in such Last Offer, but only during a [*****(***)] month period following receipt of such Last Offer and only on terms more

favorable to TOPOTARGET as the Last Offer made by CURAGEN. If, on the other hand, (i) CURAGEN gives TOPOTARGET notice that CURAGEN does not wish to enter into any such license, or (ii) CURAGEN does not respond to TOPOTARGET’s initial proposal within [********] days after receipt thereof, then TOPOTARGET shall be free to grant a license or other rights as outlined in the initial proposal to Third Parties on any terms, but only during a [*****(***)] month period following such initial proposal.

(b) For [*****(***)] months after the Effective Date, TOPOTARGET shall exclusively negotiate in good faith with CURAGEN for a license to its E2F program. At CURAGEN’s option, such license can include screening assays and/or compounds.

4.1 Members.

Draft minutes shall circulated to all members of the Joint Steering Committee sufficiently in advance of the next meeting to allow adequate review and comment prior to the meeting. Minutes shall be approved or disapproved, and revised as necessary, at the next meeting. Final minutes shall be distributed to the members of the Joint Steering Committee.

4.7 Term. The Joint Steering Committee shall exist until the termination or expiration of the Research Program and the Development Program.

4.8 Expenses. Each Party shall be responsible for all travel and related costs for its representatives to attend meetings of, and otherwise participate on, the Joint Steering Committee.

5.1 Scope of Research Program. The Parties agree to undertake a Research Program for the pre-clinical development of the First Product, including use as a combination therapy, and for pre-clinical development of Future Products. The Joint Steering Committee shall prepare, or have prepared, and provide to each Party a detailed description, mutually acceptable to the Parties in form and substance, of the activities to be undertaken during each 12-month period during the Research Program, which shall include a reasonably detailed description of the goals and scope of such research, a corresponding detailed budget for each Party, the allocation of responsibilities to the respective Parties and a work plan, milestones and project target dates for such period (including the personnel, equipment and facilities that TOPOTARGET or CURAGEN is required to provide) (each such 12-month plan, as may be updated or modified from time to time, a “Research Plan”). The objective of the Research Plan will be to allow and support US IND submissions and submissions to governmental authorities of other countries as determined by the Joint Steering Committee concerning the First Product and Future Products. The initial Research Plan is attached as Exhibit C. Each subsequent Research Plan shall be embodied in a letter agreement to be executed by the Parties and shall be finalized at least thirty (30) days prior to the end of the prior twelve-month period. The Joint Steering Committee shall regularly review, update and, as necessary, modify each Research Plan from time to time. The Joint Steering Committee shall promptly provide each Party with any such updates or modifications.

5.2 Selection of Future Products. As of the Effective Date, TOPOTARGET shall have disclosed to CURAGEN all HDAC Inhibitors that have met the conditions set forth in Exhibit D and, during the Research Term, TOPOTARGET shall promptly disclose to CURAGEN all future HDAC Inhibitors Controlled by TOPOTARGET that meet such

conditions, whether identified during the course of performance of the Research Program or otherwise. All such HDAC Inhibitors that meet the conditions set forth in Exhibit D and that are shown to have efficacy in an animal model other than the [********] model prior to or during the course of the Research Program shall be deemed Future Products for purposes of this Agreement. Each disclosure hereunder regarding an HDAC Inhibitor shall include the composition of the HDAC Inhibitor and all data with respect thereto in the possession or Control of TOPOTARGET.

(a) Subject to Section 5.3(e), on or before the first day of each calendar quarter during the Research Term, CURAGEN shall advance one fourth of the annual Research Program budget for TOPOTARGET as specified in the relevant Research Plan via wire transfer into an account designated by TOPOTARGET. Payments for any partial calendar quarter during the Research Term shall be prorated. Such payments shall cover all pre-clinical development costs incurred by TOPOTARGET in conducting the Research Plan for selected HDAC Inhibitors Controlled by TOPOTARGET and meeting the criteria in Exhibit D, including animal models of efficacy and ADME, PK, toxicology and mutagenicity studies, and including any such work related to use in combination therapy, and also including all pre-clinical studies (other than regulatory toxicity studies) for Future Products, and including all relevant product supply costs, in each case as authorized in advance by the Joint Steering Committee under each Research Plan. If any such costs include labor costs for TOPOTARGET employees, they shall be budgeted at an annual FTE rate of [*********************(********)] which amount includes an allocation of direct overhead expenses, which rate shall be revised annually at TOPOTARGET’s request subject to approval of the Joint Steering Committee. At the end of each calendar quarter, TOPOTARGET shall provide the STEERING COMMITTEE with a list itemizing expenditures and charges over the preceding quarter.

(b) At the end of each calendar year, TOPOTARGET shall provide a full accounting to CURAGEN of actual expenditures for work actually done by TOPOTARGET under the Research Plan during the preceding calendar year. If the expenses and charges of

TOPOTARGET exceed the budgeted amount for any quarter, as such budget may be amended in accordance with the terms hereof, CURAGEN shall have no obligation to reimburse TOPOTARGET for any such overrun. At the time of the final annual report, any such excess funds shall be carried forward to the next calendar year for use by TOPOTARGET in discharging its duties under the next annual Research Plan. However, in no case shall any quarterly payment by CURAGEN be reduced or withheld by CURAGEN because of any excess funds remaining in the designated account of TOPOTARGET.

(c) Costs for regulatory toxicology studies required to support the initial US IND for the First Product shall be paid from and charged against the Research Program budget as specified in Section 5.3(e). Any costs for any regulatory toxicology studies for any Future Product and for new formulations or different administration schedules of the First Product shall not be paid from or be charged against the quarterly advances made by CURAGEN pursuant to Section 5.3(a), and shall be CURAGEN’s responsibility unless CURAGEN has provided written notice within thirty (30) days of receipt of written notice of a Joint Steering Committee recommendation regarding such studies that it does not wish to fund such studies, in which event Section 7.2(d) shall apply.

(d) In no event shall costs incurred by CURAGEN in carrying out any work directed by the Joint Steering Committee under Section 5.3(f) be paid for from the funds described in Section 5.3(a) above. Such funds shall also not be used to fund any SAR chemistry or manufacturing process development work performed by TOPOTARGET or any in-vitro research as described in Section II of Exhibit C hereto performed by either Party, which work shall be funded by the Party who is to perform such work.

(e) Pursuant to Section 5.3(a), CURAGEN shall be obligated to pay a maximum of US$6,000,000 towards costs of the Research Program over the first three (3) years of the Research Program and aggregate payments shall not at any time exceed more than $500,000 per quarterly period for all quarterly periods which have elapsed since the Effective Date without CURAGEN’s prior written consent. The Joint Steering Committee may recommend an increase or an acceleration in such budget to the extent necessary to complete any

relevant work allocated to TOPOTARGET under this Agreement or under the Research Plan; provided, however, that CURAGEN shall not be required to fund any such excess amount or agree to any acceleration of payments without its prior written consent. In the event that TOPOTARGET’s budgeted expenses as approved by the Joint Steering Committee reach US$6,000,000 prior to the end of the Research Term, the Research Program shall terminate unless otherwise agreed by the Parties. Neither party shall be liable to the other party for any costs, damages, expenses or other liabilities as a result of such termination, and neither party shall have any obligation to continue work under the Research Plan following the date of such termination.

(f) If requested by the Joint Steering Committee, CURAGEN shall utilize its systems biology technologies to support the Research Program, subject to CURAGEN’s prior approvals, not to be unreasonably withheld, with advance notice to TOPOTARGET. The Joint Steering Committee may decide that CURAGEN should participate in certain activities other than as described above relating to identification and in-vitro evaluation of Future Products. If so agreed, then such activities shall be documented in writing and reported to TOPOTARGET and the Joint Steering Committee.

5.4 Conduct of Research Program. During the term of the Research Program, each Party shall:

(a) undertake an interactive, cooperative Research Program with the other Party as set forth in the Research Plans, and such other activities that the Joint Steering Committee decides, from time to time, are necessary for the scientific or commercial success of the Research Program, consistent with Article 4, this Agreement, and the intent of the Parties as evidenced by this Agreement;

(g) with respect to each Party, ensure that all of its employees and agents involved in the Research Program on such Party’s behalf agree, in writing, to assign to such Party, directly or indirectly, such Person’s entire interest in and to any and all Inventions arising from such involvement.

(a) TOPOTARGET and CURAGEN each shall maintain records in a manner suitable for carrying out the purposes of the Research Program, and in sufficient detail and in good scientific manner (which shall be complete and accurate in all material respects) and in a form required under all applicable laws and regulations. Each Party shall use reasonable efforts to maintain its records, and to require its subcontractors to do so, in an electronic form suitable

for electronic filing with any regulatory authority. In addition, TOPOTARGET shall retain records of personnel commitments and other expenditures made in support of the Research Program in sufficient detail to satisfy its reporting requirements to the Steering Committee. CURAGEN shall maintain its records in a similar form.

(b) TOPOTARGET and CURAGEN shall share all information contained in such records, and each shall have the right, during normal business hours, upon reasonable notice and subject to such reasonable procedures as the other Party may require, to inspect and copy all such records of the other Party relating specifically to the Research Program to the extent reasonably required for the performance of the inspecting Party’s obligations, or exercise of such Party’s rights, under this Agreement. TOPOTARGET and CURAGEN 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.

5.6 Material Transfer. In order to facilitate the Research Program, either Party may provide to the other Party certain biological materials or chemical compounds (collectively, the “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. Except as otherwise provided under this Agreement, all Substances delivered to the other Party shall remain the sole property of the supplying Party, shall be used only in furtherance of the Research Program or the receiving Party’s rights under this Agreement, shall remain under the sole control of the other Party. Substances shall not be used by or delivered to any Third Party except under a written Material Transfer Agreement containing terms and conditions substantially similar to those contained in the form attached as Exhibit E. Any rights to inventions acquired by either Party pursuant to any such Material Transfer Agreement shall be deemed Joint Collaboration Technology. The Substances supplied under this Section 5.6 shall not be used in research or testing involving human subjects, and must be used otherwise with prudence and appropriate caution in any experimental work, since not all of their characteristics may be known. THE SUBSTANCES ARE PROVIDED HEREUNDER “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 WILL NOT INFRINGE OR VIOLATE ANY PATENT OR OTHER PROPRIETARY RIGHTS OF ANY THIRD PARTY.

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

5.8 Term of Research Program. The term of the Research Program (“Research Term”) shall commence on the Effective Date, and shall continue until the third anniversary of the Effective Date, unless earlier terminated as provided herein; provided, however, that CURAGEN may elect, at its sole discretion, to extend the Research Term for one or more additional 12-month periods by committing to fund any such continued Research Program at a level of at least US$2,000,000 per year, such amount, to the extent greater than $2,000,000, to be negotiated in good faith, giving due consideration to prior research costs and expenses under the Research Program and mutually agreed to by the Parties on or before the expiration of the prior period. Notice of any such election shall be made, if at all, at least 90 days prior to the relevant anniversary of the Effective Date. In the event that the election is made but the parties cannot agree upon appropriate consideration by the expiration of the prior period, then the Research Program shall terminate as of such date.

(a) At any time during the term of the Research Program, either Party shall have the right to terminate the Research Program upon 30 days’ written notice to the other Party, in the event that:

(i) the other Party is acquired (whether through merger, consolidation, acquisition (directly or indirectly) of stock representing 50% or more of the outstanding voting stock or other of its equity securities, sale of all or

substantially all of its assets, or otherwise) by a Third Party which is reasonably perceived by the non-acquired Party as a competitor with respect to HDAC Inhibitors or not capable of meeting the requirements of the Research Program or the purposes of this Agreement; or

(ii) Either Party has become entitled to terminate this Agreement under clause (b) or (c) of Section 15.3.

(iii) Notwithstanding any other provisions of this Agreement, CURAGEN shall have the right to terminate the Research Program at any time after the first anniversary of the Effective Date upon three (3) months’ notice to TOPOTARGET (x) in its entirety or solely with respect to additional Future Products, and with no penalty, in the event that CURAGEN reasonably concludes, in good faith and based on the results of the Research Program and other appropriate scientific and commercial information available to CURAGEN, which conclusion and the grounds therefor shall be presented to the Joint Steering Committee in writing, that it is not likely that any additional Future Products will be identified for which an IND can properly be filed in the United States or that any Future Product which is likely to be identified for which an IND can properly be filed in the United States is not likely to be sufficiently commercially successful to warrant the cost of filing an IND and conducting the necessary clinical trial to obtain approval of an NDA in the United States; or (y) for any reason upon payment of a penalty equal to 50% of any remaining unexpended portion of the US $6,000,000 in research funding to be provided pursuant to Section 5.3. In the event the Research Program is terminated under Section 5.9(a)(iii)(x) only with respect to additional Future Products, the Parties will negotiate, in good faith, a revised budget for the continued development of then existing Collaboration Products. If the parties cannot agree upon appropriate budget within thirty (30) days, then this matter will be referred to the Chief Executive Officers of the Parties for resolution through good faith negotiations. If the budget is not agreed by such individuals within thirty (30) days, then the

Parties shall utilize a mutually agreed upon expert, who shall decide on the appropriate reductions from the current budget, if any, and whose decision will be binding on the parties.

Either Party shall promptly notify the other Party of the occurrence of any of the events specified in Sections 5.9(a)(i) or (ii).

(b) At any time during the term of the Research Program, either Party (the “terminating Party”) shall have the right to terminate the Research Program upon notice to the other Party (the “defaulting Party”) in the event the defaulting Party materially defaults with respect to any of its material obligations in connection with the Research Program and fails to cure such default within 60 days after the receipt of a notice from the terminating Party specifying the nature of, and requiring the remedy of, such default.

(c) In the event of termination of the Research Program by CURAGEN pursuant to Section 5.9(a) or (b), or by TOPOTARGET pursuant to Section 5.9(a)(i), CURAGEN may elect to have the Agreement and the license rights granted hereunder continue in effect as follows: CURAGEN shall thereafter be permitted to continue development and commercialization within the Territory with respect to the First Product and all Future Products identified pursuant to Section 5.2 prior to such termination, provided that such activities are not contrary to the terms of this Agreement and that the provisions of this Agreement are observed at all times, including, but not limited to, Section 7.2(f), Article 8 and others requiring diligence in development and commercialization, payment of fees and milestones under this Article and Article 9, and termination under Article 15. TOPOTARGET shall (i) promptly transfer to CURAGEN copies, whether in written or electronic form, of all data, reports, and records, in TOPOTARGET’s possession or control, relating to TOPOTARGET Licensed Technology and/or TOPOTARGET Collaboration Technology but only to the extent required to enable CURAGEN to continue to conduct the Research Program with respect to the Future Products identified under Section 5.2, and all to the extent not previously disclosed to CURAGEN; (ii) return to CURAGEN all relevant records and materials, whether in written or electronic form, in TOPOTARGET’s possession or control containing Confidential Information of CURAGEN and

(a) Subject to Section 7.2(c), 7.2(d) and 7.2(e), TOPOTARGET hereby grants to CURAGEN an exclusive (even as to TOPOTARGET), royalty-bearing right and license in the Field throughout the Territory, with the right to grant sublicenses in accordance with the terms of this Agreement, under the TOPOTARGET Licensed Technology, the TOPOTARGET Collaboration Technology and TOPOTARGET’s interest in the Joint Collaboration Technology to develop, have developed, make, have made, use, sell, offer for sale, and have sold, and to import, have imported, export and have exported within the Territory, Collaboration Products and, subject to Section 7.2(b), any HDAC Inhibitor that is not a Collaboration Product.

(b) From and after the date of expiration or termination of the Research Term, any HDAC Inhibitor which is not a Collaboration Product at such time, shall no longer be subject to the license granted to CURAGEN under Section 7.2(a).

(c) Notwithstanding Section 7.2(a), for any distinct Future Product for which an IND is filed in any country, whether during or after the Research Term, if CURAGEN fails to make any payment specified in Section 9.4 for such Future Product within the time period provided therein, such Future Product and its Back-Up Products shall no longer be deemed Collaboration Products and shall be removed from operation of this Agreement.

(d) In addition, for any distinct Future Product for which CURAGEN declines to fund regulatory toxicity studies recommended by the Joint Steering Committee within thirty (30) days of any written notice thereof provided to CURAGEN, such Future Product and its Back-Up Products shall no longer be deemed Collaboration Products and shall be removed from operation of this Agreement.

(e) Unless CURAGEN has designated a specific Back-Up Product as a potential replacement for a Collaboration Product within [*****(****)] years after the first filing of an IND in the Territory for such Collaboration Product, CURAGEN’s license under Section 7.2(a) to Back-Up Products for such Collaboration Product, shall terminate as of such date and such Back-Up Products shall thereafter no longer be deemed Collaboration Products. If CURAGEN has designated a Back-Up Product prior to such date, such Back-Up Product shall continue to be licensed hereunder, but rights to all non-designated Back-Up Products shall terminate at such time.

(f) In order to maintain the license rights of Section 7.2(a), CURAGEN must diligently develop and commercialize Collaboration Products. CURAGEN will have satisfied the foregoing obligation by adhering to the clinical plan for Collaboration Products as determined by the Joint Steering Committee and, meeting targets for (i) initiating clinical trials: IND within [***(****)******] following completion of regulatory toxicity studies of each Collaboration Product recommended by the Joint Steering Committee, Phase II within [***(****)******] of Phase I completion, Phase III within [***(****)******] of Phase II completion, and filing at least one (1) NDA within [***(****)******] of Phase III completion (including all necessary data analysis) and (ii) prosecuting clinical trials: spending a minimum of [******************] for clinical development (all clinical expenses including patient fees, central lab fees and CRO fees, but excluding CURAGEN internal infrastructure costs) of a Collaboration Product that is in Phase I, [******************] for clinical development of a Collaboration Product that is in Phase II and [******************] for clinical development of a Collaboration Product that is in Phase III. The failure to achieve any specific target will not mean that CURAGEN has failed to meet the foregoing obligation; provided that CURAGEN can demonstrate that it has used commercially reasonable efforts to do so. Demonstration of commercial due diligence may include, but is not limited to developing a marketing plan to market the Covered Products in the Territory reflecting activities and resources customary in the industry for similar products, submitting the marketing plan to TOPOTARGET at least six (6) months prior to launch of the first Covered Product for comment and providing annual updates thereafter, establishing (directly or indirectly) a suitable sales force and committing sufficient

marketing resources and budget to meet the objectives of the marketing plan, and meeting minimum sales targets beginning in the third calendar year after market launch in the United States.

(a) CURAGEN shall have the right to grant sublicenses to any of its Affiliates and/or to Third Parties of the licenses or rights granted to CURAGEN hereunder for purposes of permitting such Affiliate(s) or Third Party to perform CURAGEN’s rights and obligations hereunder, provided that: (i) CURAGEN shall provide TOPOTARGET written notice within 30 days of identifying said Affiliate or Third Party; (ii) the rights to be granted to any Third Party shall not include rights to any Future Product with respect to which the take up fee specified in Section 9.4 has not been paid; (iii) CURAGEN shall guarantee and be responsible for ensuring the diligent discharge of CURAGEN’s obligations under, and compliance with all applicable terms of, this Agreement, whether by CURAGEN or any Sublicensee; (iv) each Affiliate or Sublicensee agrees in writing to keep books and records and permit TOPOTARGET to review such books and records pursuant to the relevant provisions of, and to observe and to be bound by all other applicable terms of, this Agreement (including, without limitation, those set forth in Sections 8.2, 8.7, 12, 13, 15 and 17); and (v) the rights of TOPOTARGET under this Agreement are preserved in connection with any such sublicensing. CURAGEN shall promptly provide TOPOTARGET with notice of any sublicense granted pursuant to this Section 7.3. Notwithstanding the foregoing, for any sublicense with respect to a Collaboration Product which has not yet entered Phase II clinical studies, TOPOTARGET shall have the right within 20 days of any notice provided pursuant to (i) above, to prevent CURAGEN from granting such sublicense if TOPOTARGET notifies CURAGEN that it believes that such proposed Sublicensee lacks sufficient capability to conduct clinical development of such Collaboration Product, and such belief is reasonable.

(b) CURAGEN hereby unconditionally guarantees the performance of any of its Affiliates and its Sublicensees hereunder.

(c) Activities of any Sublicensee shall be subject to milestone, royalty or other payments as if the activity was conducted by CURAGEN, and CURAGEN shall make payments to TOPOTARGET on behalf of its Sublicensee, unless CURAGEN and TOPOTARGET mutually agree to allow the Sublicensee to make payments directly to TOPOTARGET.

7.4 TOPOTARGET Commercialization License. CURAGEN hereby grants to TOPOTARGET an exclusive (even as to CURAGEN), royalty-bearing right and license in the Field throughout the TOPOTARGET Territory, with the right to grant sublicenses in accordance with the terms of this Agreement, under the CURAGEN Licensed Technology, the CURAGEN Collaboration Technology and CURAGEN’s interest in the Joint Collaboration Technology to develop, have developed, make, have made, use, sell, offer for sale, and have sold, and to import, have imported, export and have exported within the TOPOTARGET Territory, Collaboration Products.

CURAGEN hereby grants to TOPOTARGET a fully paid, exclusive right and license, with the right to sublicense subject to CURAGEN’s prior written approval, which approval shall not be unreasonably withheld, to use the CURAGEN Trademarks in the TOPOTARGET Territory solely in connection with the sale or distribution of Collaboration Products substantially identical to those for which such CURAGEN Trademarks are used by CURAGEN in the Territory and for which TOPOTARGET has become obligated to pay royalties to CURAGEN pursuant to Section 9.9. TOPOTARGET agrees that prior to any such use, it will submit to CURAGEN for reasonable review samples of the labels and other materials which depict such CURAGEN Trademarks and which TOPOTARGET intends to use. TOPOTARGET further agrees to cooperate with CURAGEN in connection with CURAGEN’s reasonable efforts to exercise quality control with respect to TOPOTARGET’s use of any CURAGEN Trademark. To the extent TOPOTARGET desires CURAGEN to enforce against a Third Party the rights to any CURAGEN Trademark in the TOPOTARGET Territory, TOPOTARGET shall be responsible for all costs and expenses associated therewith. TOPOTARGET agrees that all use of any CURAGEN Trademark by TOPOTARGET shall inure to the benefit of CURAGEN and that TOPOTARGET will not undertake any effort or cause a Third Party to undertake any efforts to challenge the rights of CURAGEN to any CURAGEN

Trademark. TOPOTARGET hereby unconditionally guarantees the performance of any of its Affiliates or sublicensees with respect to any rights granted hereunder.

8.1 Development Program. The Parties agree to conduct a Development Program as further provided in this Section 8 to coordinate the global clinical development of the Collaboration Products. The Joint Steering Committee will approve specific Development Program plans for Collaboration Products in accordance with the principles outlined in Exhibit F. All risk-benefit decisions related to the development of Collaboration Products, including which pre-clinical toxicology studies and safety testing are to be performed, will be made by the Joint Steering Committee.

(a) CURAGEN shall use commercially reasonable efforts, consistent at least with those described in Section 7.2(f), (including, but not limited to, conducting clinical trials (other than the TOPOTARGET Clinical Studies), filing for regulatory approvals, diligently pursuing such approvals and, upon the grant of regulatory approval, marketing Collaboration Products) to develop, commercialize and market at least one Collaboration Product in the Field in the Territory. In connection therewith, CURAGEN shall dedicate resources to the development, commercialization and marketing of Collaboration Products in the Territory that are consistent with the resources that CURAGEN, at all relevant times, would dedicate to products containing compounds with similar commercial potential generated from CURAGEN’s own research efforts that CURAGEN decided to develop commercially and market. Except as otherwise provided in this Agreement, CURAGEN shall be solely responsible for conducting all such development, commercialization and marketing activities in the Territory, and for all costs and expenses thereof.

(b) CURAGEN shall provide TOPOTARGET and the Joint Steering Committee on a timely basis (that is, promptly after generation) with all data, results, reports and other information generated in connection with CURAGEN’s development, either alone or in

permitted collaboration with any Third Party(ies), of any Collaboration Products in the Territory. CURAGEN shall promptly inform the Joint Steering Committee regarding all significant developments and issues in connection with any such development of Collaboration Products in the Territory that may arise from time to time.

8.3 Exchange of Regulatory Information; Ownership of Regulatory Filings.

All INDs, NDAs and other regulatory filings in the Territory with respect to any Collaboration Products shall be in the name of, and be owned solely by, CURAGEN. CURAGEN shall provide to TOPOTARGET copies of all data, information and regulatory filings made or exchanged with any regulatory authority in such countries with respect to any Collaboration Product, promptly after generation of such data, information or regulatory filing. Subject to applicable laws and regulations, unless this Agreement is terminated by CURAGEN in its entirety pursuant to Section 15.3 as a result of a payment breach, CURAGEN shall provide TOPOTARGET with the right to cross-reference any such relevant existing regulatory filings and dossiers in connection with TOPOTARGET regulatory activities in the TOPOTARGET Territory.

(a) TOPOTARGET shall conduct, at CURAGEN’s expense, those clinical studies for the First Product and the Future Products in the TOPOTARGET Territory as listed on

Exhibit G attached hereto and as otherwise approved by the Joint Steering Committee (“TOPOTARGET Clinical Studies”). Notwithstanding the foregoing, CURAGEN shall not be required to pay for the expenses of any TOPOTARGET personnel involved in planning, coordinating or monitoring any such TOPOTARGET Clinical Studies.

(b) TOPOTARGET shall retain the option to conduct, or have conducted, at its own expense, any clinical trial it deems appropriate to support registrations for commercialization of Collaboration Products in the TOPOTARGET Territory; provided, however, that all protocols for such trials shall be reviewed with the Joint Steering Committee prior to initiation of any such trial.

(c) TOPOTARGET shall provide CURAGEN and the Joint Steering Committee on a timely basis (that is, promptly after generation) with all data, results, reports and other information generated in connection with TOPOTARGET’s development, either alone or in permitted collaboration with any Third Party(ies), of any Collaboration Products outside the Territory, including without limitation all data and information relating to any TOPOTARGET Clinical Studies. TOPOTARGET shall promptly inform the Joint Steering Committee regarding all significant developments and issues in connection with any such clinical studies of Collaboration Products that may arise from time to time.

(d) Notwithstanding the foregoing, the Joint Steering Committee shall have the right to require TOPOTARGET to terminate, for reasonable cause, any clinical trial of a Collaboration Product. The Parties acknowledge and agree that for purposes of this Section 8.4(d), reasonable cause shall include, without limitation, the Joint Steering Committee’s reasonable determination that [*************************************************].

8.5 Use of CURAGEN Clinical Data. Notwithstanding Section 12.1, and subject to compliance with Section 9.9, TOPOTARGET shall be permitted to use, and to allow its Affiliates and licensees to use, clinical data and information generated or obtained by CURAGEN or resulting from clinical trials paid for by CURAGEN hereunder (“CURAGEN Clinical Data”) with respect to TOPOTARGET’s efforts to obtain regulatory approval for Collaboration Products outside the Territory so long as TOPOTARGET informs CURAGEN of

any such intended use, limits the extent of any concomitant disclosure to the maximum extent possible, and provides copies to CURAGEN of any documents which embody any such CURAGEN clinical data and/or information which are to provided to any Third Party. TOPOTARGET hereby unconditionally guarantees the performance of any of its Affiliates and licensees with respect to the rights granted hereunder.

(a) The Joint Steering Committee shall establish data collection and data sharing standards, which will include without limitation, standards regarding the collection and provision to each Party of all safety data. The Parties shall use best efforts to adhere to such data collection standards.

(b) In the event of a change of control of TOPOTARGET (whether through merger, consolidation, acquisition (directly or indirectly) of stock representing 50% or more of the outstanding voting stock or other of its equity securities, sale of all or substantially all of its assets, or otherwise) which results in control of TOPOTARGET by any Third Party that, in the good faith determination of CURAGEN, is a competitor of CURAGEN and is developing an HDAC inhibitor, CURAGEN shall not be required to include in any report furnished by CURAGEN pursuant to this Agreement, or provide to any representative of TOPOTARGET (or any successor thereto), any information that CURAGEN, acting in good faith, determines to be competitively sensitive or enabling information. Nothing in this provision should be understood to restrict CURAGEN’s right to cross-reference regulatory filings and dossiers pursuant to Section 8.3 or to limit any obligation pursuant to Section 8.7 hereof.

(c) In the event of a change of control of CURAGEN (whether through merger, consolidation, acquisition (directly or indirectly) of stock representing 50% or more of the outstanding voting stock or other of its equity securities, sale of all or substantially all of its assets, or otherwise) which results in control of CURAGEN by any Third Party that, in the good faith determination of TOPOTARGET, is a competitor of TOPOTARGET and is developing an HDAC inhibitor, TOPOTARGET shall not be required to include in any report furnished by TOPOTARGET pursuant to this Agreement, or provide to any representative of CURAGEN (or

any successor thereto), any information that TOPOTARGET, acting in good faith, determines to be competitively sensitive or enabling information. Nothing in this provision should be understood to restrict TOPOTARGET’s right to cross-reference regulatory filings and dossiers pursuant to Section 8.3 or to limit any obligation pursuant to Section 8.7 hereof.

(a) The Parties shall develop standard operating procedures for the investigation and reporting of adverse events concerning Collaboration Products. The Parties shall immediately implement such agreed procedures and shall provide each other in a time frame consistent with regulatory obligations with any information which has become available to them and which is relevant to the safe use of the Collaboration Products or which is required by local law in all countries where the Collaboration Products are marketed or are in clinical trials.

(b) Both as an integral part of the procedures referred to in (a) above and as a separate obligation under this Agreement, each Party shall notify the other Party of each report of a “serious adverse event” (as defined below). The notification shall be made in the appropriate format prescribed in the said procedures by the fastest available means. The responsibility for submitting any such report to health registration authorities in particular countries shall be stipulated in the said procedures. Upon the request of one Party, the other Party shall promptly investigate a serious adverse event and shall promptly submit follow-up reports upon the receipt of new information. The said procedures are subject to such changes as may be adjudged necessary or as shall be required by applicable law. For the purposes of this provision, “serious adverse event” shall mean any adverse drug experience occurring at any dose that results in any of the following outcomes: death, a life-threatening adverse drug experience (i.e. placing the patient or subject, in the view of the investigator, at immediate risk of death from the reaction as it occurred), inpatient hospitalization or prolongation of existing hospitalization, a persistent or significant disability/incapacity, or a congenital anomaly/birth defect. Important medical events that may not result in death, be life-threatening, or require hospitalization may be considered a serious adverse event when, based upon appropriate medical judgment, they may jeopardize the

patient or subject and may require medical or surgical intervention to prevent one of the outcomes listed above.

(c) Each Party shall promptly notify the other of, and provide copies of, any proposed, pending, threatened or completed governmental action concerning adverse events which might affect any Collaboration Product.

(d) Each Party shall cooperate with the other Party to comply with any new applicable regulatory requirements on adverse drug event reporting which may from time to time be imposed in the countries where a Collaboration Product is developed, tested or marketed.

8.8 Trademarks. CURAGEN shall designate the generic name of any Collaboration Product and register such name with USAN (United States Adopted Name/International Nonproprietary Name). CURAGEN shall market the Collaboration Products throughout the Territory under trademarks (collectively, the “CURAGEN Trademarks”) selected by CURAGEN, which shall not use, incorporate or be confusingly similar to any trademark, trade name, or service mark of TOPOTARGET in existence as of the later of the Effective Date or the registration date of any such CURAGEN Trademark. CURAGEN shall own all right, title and interest in and to such CURAGEN Trademarks and shall bear all costs and expenses of registering, and maintaining the registration of, same, within or outside the Territory. TOPOTARGET may not use any marks similar to the CURAGEN Trademarks without the prior written consent of CURAGEN except as expressly set forth in Section 7.5 hereof. TOPOTARGET has retained the right to market the Collaboration Products outside the Territory and may select trademarks for such purposes in TOPOTARGET’s discretion, subject to the restrictions set forth above (collectively, the “TOPOTARGET Trademarks”). TOPOTARGET shall own all right, title and interest in and to such TOPOTARGET Trademarks and shall bear all costs and expenses of registering, and maintaining the registration of, same. CURAGEN may not use any marks similar to the TOPOTARGET Trademarks without the prior written consent of TOPOTARGET.

8.9 Publications. Each Party shall be free to publish and/or make presentations concerning the results of its development efforts under this Section 8, subject to its compliance

with this Section 8.9 and with any other guidelines established by the Joint Steering Committee. Each Party shall deliver to the other Party and the Joint Steering Committee copies of all articles and papers to be published, and reasonably detailed abstracts of presentations to be made, concerning such subject matter at least 30 days prior to the anticipated submission or presentation date thereof. The non-publishing Party shall have 30 days after receipt of said copies to object to such proposed publication or presentation because Confidential Information of such non-publishing Party is contained in the proposed publication or presentation, because such proposed publication or presentation would disclose Know-How or the proprietary and confidential details of an Invention for which such non-publishing Party has a license under this Agreement and that the Joint Steering Committee has determined, either generally or in particular, should be the subject of Patent protection. In the event the non-publishing Party makes such objection due to inclusion of the non-publishing Party’s Confidential Information, the Parties shall negotiate an acceptable version of such proposed publication or presentation. In the event that the non-publishing Party makes such objection due to the need for patent protection, then such publication or presentation shall be delayed for a reasonable period of time (not to exceed 90 days) during which the Party having responsibility therefore (under Section 6.4) shall file a patent application in the appropriate jurisdiction(s) with respect to such Know-How or Invention.

9.1 License Fee. In partial consideration of the rights and licenses granted to CURAGEN under this Agreement, within 30 days after the execution of this Agreement CURAGEN shall pay TOPOTARGET a non-refundable, non-creditable one-time license fee in the amount of US$5,000,000.

9.2 Loan Commitment. In partial consideration of the rights and licenses granted to CURAGEN hereunder, CURAGEN hereby agrees to advance certain sums to TOPOTARGET as further provided in the Convertible Debenture and Convertible Loan Agreement executed by the Parties and of even date herewith, copies of which are attached hereto in Exhibit H (the “Loan Agreements”).

In the event CURAGEN exercises its rights hereunder to terminate this Agreement pursuant to Section 15.3, CURAGEN shall have the right to accelerate the Loan and make immediate written demand for payment of all amounts due thereunder, and notwithstanding any provision of the Loan Agreements, all amounts due under the Loan shall become due and payable in cash thirty (30) days after delivery of such written demand for payment.

9.3 Additional Upfront Payment. In addition to the consideration specified above, in partial consideration of the rights and licenses granted to CURAGEN under this Agreement, CURAGEN shall pay to TOPOTARGET a non-refundable, non-creditable payment of US$5,000,000 on Phase II Initiation in the United States for the First Product, provided that such event occurs by [*************]. Otherwise, the amount payable pursuant to this Section 9.3 shall be reduced by [***********************************************************].

(a) The Parties acknowledge and agree that during the Research Program, the Parties may identify Future Products. In order to retain its rights to any such Future Products, CURAGEN shall pay to TOPOTARGET a non-refundable, non-creditable fee (the “Take Up Fee”) for each distinct Future Product within the earlier of (i) thirty (30) days after the first acceptance of the filing of an IND for such Future Product anywhere in the world or (ii) twenty-four months following the expiration or termination of the Research Term. The Take Up Fee shall be US$500,000 for each of the first two Future Products and US$1,000,000 for each Future Product thereafter.

(b) In addition, for each Future Product for which the Take Up Fee has not been paid within twelve (12) months following the expiration or termination of the Research Term, in order to retain its rights to such Future Product, CURAGEN shall pay to TOPOTARGET a non-refundable fee of [***************] (a “Maintenance Fee”) on or before such twelve-month anniversary, which amount shall be fully creditable against any Take Up Fee subsequently paid for the same Future Product. Failure to pay any such amount when due shall cause such Future Product and its Back-Up Products to be removed from operation of this Agreement as provided in Section 7.2(c).

(a) In partial consideration of the rights and licenses granted to CURAGEN under this Agreement, CURAGEN shall pay TOPOTARGET the following non-refundable, non-creditable milestone payments upon the first occurrence of each event set forth below with respect to the First Product, whether such occurrence is achieved by CURAGEN or its Affiliates or its Sublicensees (or TOPOTARGET with respect to Phase II Initiation), so long as such event occurs prior to the expiration of the Royalty Term for the First Product:

(i) US$3,000,000 upon Phase II initiation for such First Product; provided, however, that such amount shall be reduced by [***************];

(iii) [***************] upon acceptance of filing of the NDA for the First Product by the FDA;

(iv) [***************] upon acceptance of filing of the first NDA for the First Product by relevant authorities in Japan;

(v) [***************] upon First Commercial Sale of the First Product in the United States; and

(vi) [***************] upon First Commercial Sale of the First Product in Japan.

Each of the foregoing payments shall be made within 30 days after achievement of such milestone. For the avoidance of doubt, after CURAGEN has made any of the foregoing payments with respect to the First Product, CURAGEN shall have no further obligation to make the same milestone payment with respect to the First Product, or with respect to any other product which is an alternative formulation of the First Product, regardless of the number of clinical trials, NDAs or regulatory approvals for such First Product.

(b) In partial consideration of the rights and licenses granted to CURAGEN under this Agreement, CURAGEN shall pay TOPOTARGET the following non-refundable, non-creditable milestone payments upon the first occurrence of each event set forth below with respect to each Future Product, whether such occurrence is achieved by CURAGEN or its Affiliates or its Sublicensees so long as such event occurs prior to the expiration of the relevant Royalty Term:

(i) US$3,000,000 upon Phase II Initiation for such Future Product; provided, however, that such amount shall be reduced by [****************************************************************];

(iii) [************] upon acceptance of filing of the first NDA for the Future Product by the FDA;

(iv) [************] upon acceptance of filing of the first NDA for the Future Product by relevant authorities in Japan;

(v) [************] upon First Commercial Sale of the Future Product in the United States; and

Each of the foregoing payments shall be made within 30 days after achievement of such milestone. For the avoidance of doubt, after CURAGEN has made any of the foregoing payments with respect to any Future Product, CURAGEN shall have no further obligation to make the same milestone payment with respect to such Future Product, or with respect to any other Future Product that is an alternative formulation of such Collaboration Product for which milestones have been paid pursuant to Section 9.5(a) or (b) hereof, regardless of the number of clinical trials, NDAs or regulatory approvals for any such Future Product.

(c) If CURAGEN notifies TOPOTARGET that it is developing both a lead Collaboration Product and a Back-Up Product in the Territory, CURAGEN shall be obligated to pay only one set of milestones as set forth in (a) or (b) above until the acceptance for filing of an NDA on the second of such two Collaboration Products in the United States or Japan, at which time CURAGEN shall pay: (i) the specified milestone for such event; and (ii) to the extent such payments were not previously made or applicable, all preceding milestones which have been met for such second Collaboration Product, plus interest on such amounts at an annual percentage rate equal to [*********(***)] per year or the highest rate allowed under applicable law, whichever is lower, compounded annually from the date the milestone would have been met until the payment is made; and (iii) the remaining milestones for such second Collaboration Product when the specified events are achieved.

(d) If the development or commercialization of a Collaboration Product is abandoned during the term of this Agreement for any specific, medical or commercial reason after one or more of the milestone payments specified in (a) or (b) above are made, and a Back-Up Product is developed to replace the abandoned Collaboration Product, then no milestone payment shall be required with respect to the Back-Up Product to the extent that such milestone payment has already been made with respect to the abandoned Collaboration Product.

(a) In partial consideration of the rights and licenses granted to CURAGEN under this Agreement, CURAGEN shall pay TOPOTARGET a royalty on Net Sales of each Covered Product, commencing on the First Commercial Sale of each such Covered Product by or on behalf of CURAGEN, its Affiliates or its Sublicensees in each country in the Territory and continuing during the Royalty Term for such Covered Product for such country, in an amount calculated by multiplying the applicable percentage (i.e., the royalty payable thereon) from the following chart by the aggregate Net Sales of each such Covered Product throughout the Territory during each calendar year (or portion thereof) during the term of this Agreement:

(b) CURAGEN’s obligation to pay royalties with respect to each Covered Product in each country in the Territory shall expire upon the expiration of the Royalty Term with respect to such Covered Product in such country.

(c) The obligation to pay royalties to TOPOTARGET under this Section 9.6 is imposed only once with respect to the same unit of Covered Product, regardless of the number of Patents pertaining thereto.

(a) CURAGEN, at its sole expense, shall pay all license fees, milestones and earned royalties owing to any Third Party with respect to patents regarding the composition or method of manufacture of the HDAC Inhibitor component of any Collaboration Product (“Third Party HDAC Patents”) that CURAGEN determines, in its reasonable business judgment, are necessary in order to develop, make, have made, use, sell, offer for sale, have sold or export any such Collaboration Product in the Territory (collectively, “Third Party HDAC Royalties”).

(b) CURAGEN shall be entitled to a credit against royalties due to TOPOTARGET under this Agreement for any Covered Product in an amount equal to [******]

of the aggregate Third Party HDAC Royalties paid by CURAGEN in any country in the Territory with respect to the relevant Covered Product; provided, however, that the application of such credit shall not reduce the royalties payable by CURAGEN under this Agreement for such Covered Product with respect to any given calendar quarter by more than [******]. Notwithstanding the foregoing, if CURAGEN, in lieu of or in addition to any Third Party HDAC Royalties, is required to pay an award of damages or a settlement amount in the form of a reasonable royalty based on sales during any period of previous infringement of any Third Party HDAC Patents (as opposed to the on-going payment of a running royalty), then such payment shall be allocated to the several calendar quarters during such period of infringement, and the limits set forth in the previous sentence shall apply to each portion of such payment allocated to a specific quarter and not to such payment as a whole, and an appropriate credit shall be permitted so long as no quarterly payment is reduced by more than [******].

(c) Each Party, at its sole expense, shall pay all license fees, milestones and earned royalties owing to any Third Party as a result of the licensing of Patents other than Third Party HDAC Patents (“Other Third Party Patents”), that the Joint Steering Committee determines, in its reasonable business judgment, are necessary in order to develop, make, have made, use, sell, offer for sale, have sold or export any Collaboration Product in its respective territory (collectively, “Other Third Party Royalties”). All such amounts that are due with respect to a particular country shall be borne by the Party in whose territory such country falls hereunder. All other amounts shall be allocated based on the ratio of affected sales in each Party’s territory, as mutually agreed by the Parties.

(d) Each Party shall be entitled to a credit against royalties due to the other Party under this Agreement on any Covered Product from CURAGEN pursuant to Section 9.6, or on any Collaboration Product from TOPOTARGET pursuant to Section 9.9. in each case in an amount equal to [******] of the aggregate Other Third Party Royalties paid by such Party in any country in its territory; provided, however, that the application of such credit shall not reduce the royalties payable by such Party under this Agreement for such Covered Product or Collaboration Product, as relevant, with respect to any given calendar quarter, after any adjustment permitted to CURAGEN pursuant to (b) above where CURAGEN has paid both Third Party HDAC Royalties

and Other Third Party Royalties, by more than [******]. Notwithstanding the foregoing, if such Party, in lieu or in addition to any Other Third Party Royalties, is required to pay an award of damages or a settlement amount in the form of a reasonable royalty based on sales during any period of previous infringement of Other Third Party Patents (as opposed to the on-going payment of a running royalty), then such payment shall be allocated to the several calendar quarters during such period of infringement, and the limits set forth in the previous sentence shall apply to each portion of such payment allocated to a specific quarter and not to such payment as a whole, and an appropriate credit shall be permitted so long as no quarterly payment is reduced by more than [******].

9.8 Royalty Increases. Notwithstanding any provision herein to the contrary, TOPOTARGET shall have the right, at its sole option, to share in the expenses of developing any Collaboration Product in the Territory and increase the royalties due to TOPOTARGET on sales of the resulting Covered Product(s) in the Territory as follows:

(a) TOPOTARGET must notify CURAGEN of its desire to exercise its option to increase royalties pursuant to this Section 9.8 by delivering written notice thereof to CURAGEN prior to Phase III Initiation of the relevant Collaboration Product;

(b) TOPOTARGET shall pay CURAGEN [*******(****)] of the development costs incurred by CURAGEN, its Affiliates and Sublicensees with respect to such Collaboration Product, including any Research Program funding provided by CURAGEN under Section 5.3 and excluding any milestones paid under Section 9, prior to the date of such notice, within thirty (30) days of receipt of an invoice from CURAGEN for such costs;

(c) TOPOTARGET shall, from and after the date of such notice, be responsible for [*******(****)] of all future development costs for such Collaboration Product and shall make payments therefore within ten (10) days of receipt of monthly invoices for such expenses from CURAGEN; and

(d) Subject to TOPOTARGET making all payments specified above in full, the royalties on the relevant Covered Product(s) shall thereafter be as follows instead of as stated in Section 9.6:

9.9 Royalties to CURAGEN. In the event that TOPOTARGET exercises its rights as provided in Section 8.5 to use CURAGEN Clinical Data, and makes any material use of any CURAGEN Clinical Data in connection with any registration or marketing of any Collaboration Product in the TOPOTARGET Territory, whether by itself or in collaboration with any Third Party, TOPOTARGET shall notify CURAGEN of such use and shall become obligated to make royalty payments to CURAGEN as partial consideration for access to such clinical data and the investment made by CURAGEN therein. Unless otherwise provided in Section 15.6(c), royalty payments shall be owed to CURAGEN at the rates specified in Section 9.6 on the Net Sales in the TOPOTARGET Territory of each Collaboration Product with respect to which such CURAGEN Clinical Data was used or whose use or sale in the relevant country is covered by one or more Valid Claims of CURAGEN Licensed Technology or the CURAGEN Collaboration Technology. The Parties hereby agree that, unless a shorter period is otherwise provided in Section 15.2, such payments shall continue in each country for the duration of any Royalty Term

for a corresponding Covered Product in such country, notwithstanding the fact that such royalties are being provided as consideration for access to rights which are not necessarily patent rights. All such payments shall be subject to the Net Sales definition as if each such Collaboration Product was a Covered Product therein, and shall be subject to the Third Party Royalty provisions of Section 9.7(c) and (d) and the reporting and payment provisions as provided in Section 10, with the rights and obligations of the Parties under such definition and such Sections reversed. Notwithstanding the foregoing, royalty payments due to CURAGEN under this Section 9.9 during any royalty period shall be applied as a credit against any milestones and royalties owed by CURAGEN to TOPOTARGET on any or all Collaboration Products during the relevant royalty period; provided, however, that if any credit cannot be fully utilized in any royalty period, it shall be carried forward into future periods until exhausted, and such future credits shall accrue interest at the rate of [********(****)] compounded annually. Other than as provided in Article 15, TOPOTARGET shall not be obligated to submit actual payment of any royalty calculated to be due hereunder to CURAGEN.

10.1 Payment. Except as otherwise provided in this Agreement, all royalty and other payments due hereunder shall be paid quarterly within 45 days after the end of each calendar quarter. Each such payment shall be accompanied by a statement, Covered Product-by-Covered Product and country-by-country, of the amount of Net Sales during such quarter and the amount of royalties due on such Net Sales.

10.2 Mode of Payment. CURAGEN shall make all payments required under this Agreement as directed by TOPOTARGET from time to time, in U.S. Dollars (except as provided in Section 10.6). All royalties due hereunder shall first be determined in the currency of the country in which the Covered Products in question were sold and then converted into equivalent U.S. funds. The exchange rate for such conversion shall be that rate quoted in The Wall Street Journal on the last business day of the applicable reporting period.

10.3 Records Retention. CURAGEN, its Affiliates and its Sublicensees shall keep complete and accurate records pertaining to the sale of Covered Products in the Territory and

covering all transactions from which Net Sales are derived for a period of three calendar years after the year in which such sales occurred, and in sufficient detail to permit TOPOTARGET to confirm the accuracy of royalty payments due hereunder.

10.4 Audit Request. At the request and expense (except as provided below) of TOPOTARGET, CURAGEN, its Affiliates and its Sublicensees shall permit an independent, certified public accountant appointed by TOPOTARGET and reasonably acceptable to CURAGEN, at reasonable times and upon reasonable notice, to examine those records and all other material documents relating to or relevant to Net Sales in the possession or control of CURAGEN, its Affiliates or its Sublicensees, for a period of three calendar years after the year in which such royalties have accrued. The results of any such examination shall be made available to both Parties. If, as a result of any inspection of the books and records of CURAGEN, its Affiliates or its Sublicensees, it is shown that CURAGEN’s royalty payments under this Agreement were less than the amount which should have been paid, then CURAGEN shall make all payments required to eliminate any discrepancy revealed by said inspection within 45 days after TOPOTARGET’s demand therefor. Furthermore, if the aggregate royalty payments CURAGEN made were less than [********] of the amount which should have been paid made during the period in question, CURAGEN shall also reimburse TOPOTARGET for the reasonable out-of-pocket cost of such inspection.

10.5 Taxes. In the event that CURAGEN is required to withhold any tax to the tax or revenue authorities in any country in the Territory in connection with any payment to TOPOTARGET due to the laws of such country, such amount shall be deducted from the royalty or other payment to be made by CURAGEN, and CURAGEN shall notify TOPOTARGET and promptly furnish TOPOTARGET with copies of any tax certificate or other documentation evidencing such withholding. Each Party agrees to cooperate with the other Party in claiming exemptions from such deductions or withholdings under any agreement or treaty from time to time in effect.

10.6 Blocked Currency. If by law, regulations or fiscal policy of a particular country in the Territory, remittance of royalties in United States Dollars is restricted or forbidden, written

notice thereof shall promptly be given to TOPOTARGET, and payment of the royalty shall be made by the deposit thereof in local currency to the credit of TOPOTARGET in a recognized banking institution reasonably designated by TOPOTARGET by written notice to CURAGEN. When in any country in the Territory the law or regulations prohibit both the transmittal and the deposit of royalties on sales in such country, royalty payments shall be suspended for as long as such prohibition is in effect and as soon as such prohibition ceases to be in effect, all royalties that CURAGEN would have been under an obligation to transmit or deposit but for the prohibition shall forthwith be deposited or transmitted, to the extent allowable.

(a) Until the completion of any transfer of responsibility to CURAGEN as provided in (b) below, TOPOTARGET shall use reasonable commercial efforts, to the extent it is reasonably capable of doing so, to supply CURAGEN, itself or through TOPOTARGET’s use of Third Party manufacturers, with CURAGEN’s requirements for Collaboration Products for use under this Agreement. The cost to CURAGEN of Collaboration Products supplied for use in the Development Program for studies conducted at CURAGEN’s expense, including without limitation studies conducted under the CRADA so long as CURAGEN has rights to use all resulting data in the Territory, shall be [********] of the invoiced price TOPOTARGET pays therefor or [********] of TOPOTARGET’s fully burdened cost of goods sold (which cost shall not include process development costs). Any supply for commercial purposes shall be at a price to be agreed for each Collaboration Product, assuring a reasonable profit to TOPOTARGET. TOPOTARGET shall manufacture Collaboration Products, or shall cause TOPOTARGET’s Third Party manufacturers to manufacture same, in accordance with current Good Manufacturing Practices under 21 C.F.R. 210 and 211 and all applicable laws, rules and regulations. TOPOTARGET shall provide CURAGEN with copies of, or permission to reference, as appropriate, any Drug Master File or similar filing (“DMF”) made by TOPOTARGET with respect to any Collaboration Product, and shall not withdraw or modify any such DMF without prior written notice to CURAGEN. TOPOTARGET shall promptly notify CURAGEN of any

event which could materially affect TOPOTARGET’s ability to supply Collaboration Product to CURAGEN hereunder, and shall provide to CURAGEN copies of any correspondence with any regulatory authority that relates to its manufacturing activities with respect to Collaboration Products.

(b) Upon request of CURAGEN delivered at any time after the conclusion of the Research Term, TOPOTARGET shall give reasonable consideration to and agrees to discuss with CURAGEN in good faith the possibility of transferring responsibility for manufacturing Collaboration Products for use by CURAGEN from TOPOTARGET to CURAGEN. Any such proposal must take into consideration TOPOTARGET’s own needs for a reliable and economical supply of Collaboration Products.

11.2 Negotiation, Execution of Supply Agreement. Promptly upon request by CURAGEN, the Parties shall negotiate, diligently and in good faith, and execute a supply agreement (the “Supply Agreement”) pursuant to which TOPOTARGET shall sell to CURAGEN, and CURAGEN shall purchase from TOPOTARGET, CURAGEN’s commercial requirements of Collaboration Products as provided in Section 11.1(a) above.

11.3 Cost of Manufacturing and Related Activities. Except as expressly provided to the contrary in this Section 11, each Party shall be solely responsible for all of the costs and expenses it has incurred before, or incurs after, the Effective Date, in connection with the manufacture of any Collaboration Product.

11.4 Manufacturing Liaisons. Each Party shall have the right to appoint one employee or consultant to act as a liaison between TOPOTARGET’s and CURAGEN’s relevant manufacturing teams. Each Party shall inform the other Party’s liaison regarding the status of such Party’s manufacturing-related efforts (including scale-up, process development and actual manufacturing) under this Agreement and/or the Supply Agreement, and the two liaisons shall coordinate such efforts with the Parties’ performance of their other respective obligations under this Agreement and/or the Supply Agreement.

12.1 Confidentiality; Exceptions. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Parties agree that, during the term of this Agreement and for five years thereafter each Party, its Affiliates and its Sublicensees, if any (collectively, a “receiving Party”), shall use their best efforts to keep completely confidential, shall not publish or otherwise disclose and shall not use for any purpose other than the performance of this Agreement both the financial terms of this Agreement and any information furnished to it by the other Party, its Affiliates or its Sublicensees, if any (collectively, a “disclosing Party”), or developed under or in connection with the Research Program or any product development efforts pursuant to this Agreement (and shall ensure that its and its Affiliates’ and its Sublicensees’ respective directors, officers, employees or agents do likewise), 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; or, (ii) with respect to information disclosed by one Party to the other Party (a) was already known to the receiving Party at the time of disclosure by the disclosing Party; (b) was lawfully disclosed to the receiving Party by a Third Party who was not in default of any confidentiality obligation to the disclosing Party; or (c) is independently developed by or for the receiving Party without reference to or reliance upon the information furnished by the disclosing Party (all such information to which none of the foregoing exceptions applies, “Confidential Information”).

12.2 Exclusions to Confidentiality. The restrictions contained in Section 12.1 shall not apply to any Confidential Information in the hands of a receiving Party to the extent that it (i) is submitted by the receiving Party to governmental authorities to facilitate the issuance of marketing approvals for a Collaboration Product in accordance with the terms of this Agreement, provided that reasonable measures shall be taken to assure confidential treatment of such information, if practicable; (ii) is provided by a Party to any Third Party 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 in accordance with the terms hereof; or (iii) is otherwise required to be disclosed in compliance with applicable laws or regulations (including, without

limitation, to comply with any governmental or stock exchange disclosure requirements) or an order by a court or other regulatory body having competent jurisdiction; provided, however, that if a receiving Party is required to make any such disclosure of the disclosing Party’s Confidential Information such receiving Party shall, 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 best efforts to secure confidential treatment of such Confidential Information required to be disclosed.

12.3 Injunctive Relief. The Parties acknowledge that monetary 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 under this Agreement, at law or in equity, it shall be entitled to injunctive relief for the enforcement of its rights under this Section 12, without the posting of a bond or other security, and to an accounting of profits made during the period of any breach of the receiving Party’s obligations under this Section 12.

(a) Each Party shall notify the other promptly after such Party becomes aware of any alleged infringement in the Field of any Patent licensed to either Party under this Agreement in any country. CURAGEN shall have the first right, but not the duty, to institute patent infringement actions against Third Parties with respect to any such alleged infringement in the Field and in the Territory. CURAGEN shall take all such actions under this Section 13.1(a) (other than with respect to a Patent included solely in the CURAGEN Collaboration Technology) in reasonable consultation with TOPOTARGET and shall keep TOPOTARGET apprised as to the status of any such infringement action CURAGEN institutes. TOPOTARGET shall execute all reasonable, necessary and proper documents and take such actions, at CURAGEN’s request and expense, as shall be appropriate to allow CURAGEN to institute and prosecute infringement actions under this Section 13.1(a).

(b) The costs and expenses of bringing and maintaining any infringement action under Section 13.1(a) shall be borne solely by CURAGEN.

(c) Any award or compensation (including the fair market value of non-monetary compensation) paid by Third Parties as a result of any infringement action brought by CURAGEN under Section 13.1(a) (whether by way of settlement or otherwise) shall be allocated first to reimbursement of CURAGEN for all expenses incurred by it in connection with such action. Any remaining award or compensation shall be allocated to the Parties in the following proportions: [*************************************************].

(d) In the event CURAGEN elects not to, or fails to, exercise its rights under Section 13.1(a) with respect to any alleged infringement of a Patent licensed to CURAGEN under this Agreement (i.e., excluding any Patent included solely in the CURAGEN Collaboration Technology) within 120 days after receiving notice thereof, TOPOTARGET shall have the right, but not the duty, to institute patent infringement actions against Third Parties with respect to any such alleged infringement. TOPOTARGET shall take all such actions under this Section 13.1(d) in reasonable consultation with CURAGEN and shall keep CURAGEN apprised as to the status of any such infringement action TOPOTARGET institutes. CURAGEN shall execute all reasonable, necessary and proper documents and take such actions, at TOPOTARGET’s request and expense, as shall be appropriate to allow TOPOTARGET to institute and prosecute infringement actions under this Section 13.1(d). The costs and expenses of bringing and maintaining any infringement action under this Section 13.1(d) shall be borne solely by TOPOTARGET, and TOPOTARGET shall be entitled to retain any award or compensation (including the fair market value of non-monetary compensation) paid by Third Parties as a result of any such action.

(a) Each Party shall notify the other Party promptly in writing of any claim of, or action for, infringement of any Patents owned or licensed by Third Parties which is threatened, made or brought against either Party by reason of either Party’s performance of its

obligations under this Agreement or manufacture, use or sale of any Collaboration Products in the Territory in the Field.

(b) In the event that such an action for infringement is commenced solely against a Party or both Parties jointly and/or any of their respective Affiliates or Sublicensees, as the case may be, with respect to any Collaboration Product developed and commercialized by CURAGEN, its Affiliates and/or Sublicensees, CURAGEN shall defend such action at its own expense, and TOPOTARGET hereby agrees to assist and cooperate with CURAGEN to the extent necessary in the defense of such suit, in accordance with Section 13.2(c). CURAGEN shall have the right to settle any such action or consent to an adverse judgment thereto, and TOPOTARGET’s consent shall not be required unless such settlement or consent: (i) imposes any material obligation on TOPOTARGET (including under Section 13.2(d)), or (ii) materially impairs TOPOTARGET’s rights in or to any TOPOTARGET Licensed Technology, TOPOTARGET Collaboration Technology, CURAGEN Collaboration Technology and/or Joint Collaboration Technology, in which event TOPOTARGET’s consent shall not be unreasonably withheld or delayed.

(c) The costs of defending any infringement action with respect to a Collaboration Product developed and commercialized by CURAGEN, its Affiliates and/or Sublicensees shall be borne solely by CURAGEN.

(d) Subject to Section 9.6(b), during the pendency of any such action, CURAGEN shall continue to pay all royalties due hereunder and CURAGEN shall be fully liable for the payment of any award for damages, or any amount due pursuant to any settlement entered into by CURAGEN, to the extent that any such action pertains to a Collaboration Product developed and commercialized by CURAGEN and/or its Affiliates or Sublicensees.

(e) Except to the extent that the provisions of Section 13.1 shall apply to any portion thereof, CURAGEN shall retain any award or compensation (including the fair market value of non-monetary compensation) received by CURAGEN as a result of any such action (i.e., as a result of a counterclaim).

(f) In the event that such an action for infringement is commenced solely against a Party or both Parties jointly and/or any of their respective Affiliates or sublicensees, as the case may be, with respect to any Collaboration Product developed and commercialized by TOPOTARGET, its Affiliates and/or sublicensees, TOPOTARGET shall defend such action at its own expense, and CURAGEN hereby agrees to assist and cooperate with TOPOTARGET to the extent necessary in the defense of such suit, in accordance with Section 13.2(g). TOPOTARGET shall have the right to settle any such action or consent to an adverse judgment thereto, and CURAGEN’s consent shall not be required unless such settlement or consent: (i) imposes any material obligation on CURAGEN (including under Section 13.2(h)), or (ii) materially impairs CURAGEN’s rights in or to any TOPOTARGET Licensed Technology, TOPOTARGET Collaboration Technology, CURAGEN Collaboration Technology and/or Joint Collaboration Technology, in which event CURAGEN’s consent shall not be unreasonably withheld or delayed.

(g) The costs of defending any infringement action with respect to a Collaboration Product developed and commercialized by TOPOTARGET, its Affiliates and/or sublicensees shall be borne solely by TOPOTARGET.

(h) During the pendency of any such action, TOPOTARGET shall continue to pay any royalties due hereunder. TOPOTARGET shall be fully liable for the payment of any award for damages, or any amount due pursuant to any settlement entered into by TOPOTARGET, to the extent that any such action pertains to a Collaboration Product developed and commercialized by TOPOTARGET and/or its Affiliates or sublicensees.

(i) Except to the extent that the provisions of Section 13.1 shall apply to any portion thereof, TOPOTARGET shall retain any award or compensation (including the fair market value of non-monetary compensation) received by TOPOTARGET as a result of any such action (i.e., as a result of a counterclaim).

CURAGEN shall indemnify and hold TOPOTARGET and its Affiliates and their respective directors, officers, employees and agents, harmless from and against any and all liabilities, damages, losses, costs and expenses (including the reasonable fees of attorneys and other professionals and other reasonable litigation expenses) arising out of or resulting from:

(i) any and all product liability claims resulting from the development and/or commercialization of any Collaboration Product by CURAGEN, its Affiliates or its Sublicensees; and

(ii) any warranty claims, Collaboration 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 Collaboration Product by CURAGEN, its Affiliates or its Sublicensees due to any negligence, recklessness or intentional misconduct by, or strict liability of, CURAGEN, its Affiliates or its Sublicensees, and their respective directors, officers, employees and agents.

15.3 Termination For Cause. Each Party shall have the right to terminate this Agreement, upon notice to the other Party, in the event that:

(a) Such other Party materially defaults with respect to any of its material obligations under this Agreement and does not cure such default within [*****] days after the receipt of a notice in writing from the non-breaching Party specifying the nature of, and requiring the remedy of, such default (or, if such default cannot be cured within such [*****]-day period, if the breaching Party does not commence cure within such [*****] day period and thereafter diligently continue actions to cure and actually cure same within a period of [*************] days following such notice); provided, however, that such right to terminate shall be stayed with respect to alleged payment breaches in the event that during such [*****]-day period, the Party alleged to have been in default with respect to any payment due hereunder shall have paid all undisputed amounts and shall have initiated dispute resolution in accordance with Section 17.15 with respect to any disputed payment default, which dispute resolution the Parties shall use their best efforts to have conducted and completed within [*****] months of initiation, and which stay shall last until [*********] days following resolution of any such dispute and determination of what, if any, payments are in default.; provided, further, that if such payment dispute is not resolved within [*********] months as provided above, in order for the stay to continue, [*****] of any amount then is dispute must be prepaid to the non-breaching Party on or before such [*****] month date, which prepayment shall be credited against any amount found to be due or repaid within [*****] days following resolution of such dispute to the extent all or any portion of it is determined not to be due upon. resolution of such dispute.

Notwithstanding the foregoing, if any such non-payment default is limited to the breaching Party’s obligations with respect to a particular Collaboration Product and/or a particular country, then any termination of this Agreement under this clause (a) due to such default shall be limited to the breaching Party’s rights under this Agreement with respect to such Collaboration Product and/or country unless termination in all countries is otherwise expressly provided below.

Any termination pursuant to this clause (a) shall be without prejudice to any of the non-breaching Party’s other rights under this Agreement, and in addition to any other remedies available to it by law or in equity;

(b) The other Party shall have: (i) voluntarily commenced any proceeding or filed any petition seeking relief under the bankruptcy, insolvency or other similar laws of any jurisdiction, (ii) applied for, or consented to, the appointment of a receiver, trustee, custodian, sequestrator, conciliator, administrator or similar official for it or for all or substantially all of its property, (iii) filed an answer admitting the material allegations of a petition filed against or in respect of it in any such proceeding, (iv) made a general assignment for the benefit of creditors of all or substantially all of its assets, (v) admitted in writing its inability to pay all or substantially all of its debts as they become due, or (vi) taken corporate action for the purpose of effecting any of the foregoing;

(d) In the event that TOPOTARGET becomes administered in bankruptcy, or goes into insolvent liquidation:

(i) This Agreement will remain in effect and binding upon the Parties if the trustee in bankruptcy decides to be subrogated to the rights and obligations of TOPOTARGET according to this Agreement.

(ii) Notwithstanding the foregoing, in the event that TOPOTARGET becomes administered in bankruptcy or goes into insolvent liquidation, TOPOTARGET shall, without any further notice and with immediate effect, transfer and assign to CURAGEN (A) all or, at CURAGEN’s option, part of TOPOTARGET’s right, title and interest in the Territory in and to any of the TOPOTARGET Licensed Technology, the TOPOTARGET Collaboration Technology and the Joint Collaboration Technology, and all data, reports, records, material and other intellectual property owned or controlled by TOPOTARGET, in each case solely to the extent that they have been licensed to CURAGEN under this Agreement, and in each case solely to the extent related to the Collaboration Products then included in the licenses granted to CURAGEN under this Agreement, (B) the full and complete right to file patent applications in the name of the CURAGEN, its designee, or in TOPOTARGET’s name at CURAGEN, or its designee’s election, on the aforesaid inventions, discoveries and applications in the Territory; (C) the entire right, title and interest in and to any Letters Patent which may issue thereon in the United States or in any country in the Territory, and any renewals, revivals, reissues, reexaminations and extensions thereof, and any patents of confirmation, registration and importation of the same; and (D) the entire right, title and interest in all Convention and Treaty Rights of all kinds thereon, including without limitation all rights of priority in any country of the world, in and to the above inventions, discoveries and applications.

the estate thereof in equal monthly installments over [*******(****)] years following the date of determination of such fair market value by such independent expert. Such transfer or assignment shall be effective as from the date on which the trustee in bankruptcy decides not to be subrogated to the rights and obligations of TOPOTARGET according to this Agreement in accordance with the Danish Act on Bankruptcy, chapter 7, or when the trustee in bankruptcy or the liquidator decides to transfer or assign the TOPOTARGET Licensed Technology, the TOPOTARGET Collaboration Technology and/or TOPOTARGET’s interest in the Joint Collaboration Technology to a Third Party. If, however, the trustee in bankruptcy decides to be subrogated to the rights and obligations of TOPOTARGET according to this Agreement, such assignment and transfer shall not occur.

(iii) In case the assignment or transfer as mentioned in the previous section cannot be carried out, regardless of the reason, and the trustee in bankruptcy has decided not to be subrogated to the rights and obligations of TOPOTARGET according to this Agreement, CURAGEN shall in any event have a right of first refusal to purchase the right, title and interest in the Territory in and to any of the TOPOTARGET Licensed Technology, the TOPOTARGET Collaboration Technology and the Joint Collaboration Technology, and all data, reports, records, materials and other intellectual property owned or controlled by TOPOTARGET that have been licensed to CURAGEN under this Agreement, upon receipt from the trustee in bankruptcy of an offer to purchase such right, title and interest from an independent third party, at the same price and conditions as such third party has offered. Further, in case neither the assignment nor the right of first refusal can be carried through, CURAGEN shall in such case have a preemption right to purchase the right, title and interest in the Territory in and to any of the TOPOTARGET Licensed Technology, the TOPOTARGET Collaboration Technology and the Joint Collaboration Technology, and all data, reports, records, materials and other intellectual property owned or controlled by TOPOTARGET that have been licensed to CURAGEN under this Agreement at a fixed fair market value determined by an independent expert chosen by the Danish Institute of State Authorized Public Accountants (in Danish: Foreningen af Statsautoriserede Revisorer) if the trustee in bankruptcy or the liquidator decides to transfer or assign the TOPOTARGET Licensed Technology, the TOPOTARGET

Collaboration Technology and/or TOPOTARGET’s interest in the Joint Collaboration Technology or at the latest at the time of winding up of the bankruptcy estate. CURAGEN shall from the date on which the trustee in bankruptcy decides not to subrogate and until either the right of first refusal or the pre-emption right is exercised be entitled to make any and all necessary payments and take any necessary actions in order to maintain relevant patents. Further, CURAGEN shall from the date on which the trustee in bankruptcy decides not to subrogate and until either the right of first refusal or the pre-emption right is exercised be entitled to continue the use of the TOPOTARGET Licensed Technology, the TOPOTARGET Collaboration Technology and the Joint Collaboration Technology subject to continued payment by CURAGEN according to the terms of this Agreement during such period. Any and all costs, including license payments made after the effective date of the valuation, incurred by CURAGEN according to these rights of CURAGEN, shall be set off against the final purchase amount according to clause (iii) (right of first refusal or pre-emption right).

(iv) In the event of any assignment or transfer to CURAGEN pursuant to clause (ii) CURAGEN shall have no further obligation to pay any milestones or royalties under this Agreement.

15.4 Termination Without Cause by CURAGEN. Notwithstanding any other provision of this Agreement, after the expiration or termination of the Research Term, CURAGEN shall have the right to terminate this Agreement, in its entirety or with respect to any particular Collaboration Product and/or country in the Territory, at any time upon three (3) months’ notice in writing to TOPOTARGET. Termination under this Paragraph shall automatically terminate any and all relevant CURAGEN license rights and relevant sublicenses granted hereunder by CURAGEN.

(a) Upon any voluntary termination of any rights or licenses by CURAGEN pursuant to Section 15.4, any and all relevant licenses granted to CURAGEN hereunder, and all

relevant sublicenses, shall terminate and TOPOTARGET shall thereafter have rights as provided in Section 15.6(a) hereof with respect to such terminated rights, and shall retain its rights as provided in Section 15.6(b).

(b) Upon any termination under this Agreement by TOPOTARGET pursuant to Section 15.3 other than as a result of any payment breach or any breach of Section 7.2(f), CURAGEN shall retain its rights to exploit the licenses granted pursuant to Section 7.2 for the First Product and for all Future Products for which CURAGEN has paid any Take Up Fee as provided in Section 9.4, and, subject to Section 7.2(e), for all corresponding Back-Up Products, in all cases subject to continued compliance with the relevant terms of this Agreement. TOPOTARGET shall retain its rights as provided in Section 15.6(b).

(c) Upon any termination of this Agreement by TOPOTARGET pursuant to Section 15.3 as a result of a payment breach, CURAGEN shall no longer have rights to any Collaboration Products in any countries in the Territory and any and all licenses granted to CURAGEN hereunder, and all sublicenses, shall terminate. TOPOTARGET shall thereafter have rights as provided in Section 15.6(a) with respect to all Collaboration Products in all countries, and shall retain its rights as provided in Section 15.6(b).

(d) Upon any termination under this Agreement by TOPOTARGET pursuant to Section 15.3 as a result of a breach of Section 7.2(f) and not also as a result of a payment breach, CURAGEN shall no longer have rights in the Territory with respect to the relevant Collaboration Products for which breach of Section 7.2(f) was grounds for termination and any and all relevant licenses granted to CURAGEN, and all relevant sublicenses, shall terminate for the relevant Collaboration Product. However, CURAGEN shall retain its rights to exploit the licenses granted pursuant to Section 7.2 for all other Collaboration Products. TOPOTARGET shall thereafter have rights as provided in Section 15.6(a) for those Collaboration Products which were the subject of the breach of Section 7.2(f), and shall retain its rights as provided in Section 15.6(b).

(e) Upon termination under this Agreement by CURAGEN pursuant to 15.3, CURAGEN shall retain its rights to exploit the licenses granted pursuant to Section 7.2 for the

First Product and for all Future Products identified prior to such termination and, subject to Section 7.2(e), for all corresponding Back-Up Products, subject to continued compliance with the relevant terms of this Agreement, including without limitation payment obligations, other than those requiring collaboration with TOPOTARGET. In addition, the rights granted to CURAGEN pursuant to Section 3.5 shall survive such termination and CURAGEN shall receive additional rights as provided in Section 15.6(c). Notwithstanding the foregoing, in the event that any such termination by CURAGEN is the result of a payment breach by TOPOTARGET, the Territory as defined herein shall become worldwide and CURAGEN’s continuing rights pursuant to Section 7.2 shall be exclusive in such expanded Territory and TOPOTARGET’s rights pursuant to Sections 7.4, 7.5 and 8.5 shall terminate with respect to all Collaboration Products.

(a) For all Collaboration Products for which CURAGEN’s rights do not continue following termination as provided in Sections 15.5(a), (b), (c), or (d) above, subject to (x) and (y) below, CURAGEN shall have no further rights pursuant to Section 7.2 for the relevant Collaboration Products following such termination and CURAGEN shall:

(i) transfer and assign to TOPOTARGET all of CURAGEN’s right, title and interest in and to any CURAGEN Collaboration Technology and all data, reports, records, materials and other intellectual property owned or controlled by CURAGEN that relates exclusively to such Collaboration Products;

(ii) grant TOPOTARGET a non-exclusive license, solely for the purpose of TOPOTARGET’s developing, making, having made, using, marketing and selling such Collaboration Products, under any CURAGEN Licensed Technology and CURAGEN Collaboration Technology that does not exclusively relate to such Collaboration Products;

(iii) transfer and assign to TOPOTARGET ownership of all INDs, NDAs and other regulatory filings made or filed with respect to any such Collaboration Product (or, if such transfer and assignment is not permitted under

the laws of any applicable jurisdiction, CURAGEN shall take such other permitted actions with respect to such filings as may be reasonably requested by TOPOTARGET);

all upon commercially reasonable, arms length financial terms, which shall in no event exceed royalties in amounts as specified in Section 9.9, that the Parties shall negotiate in good faith and agree upon as soon as practicable after such termination of this Agreement. In the event the Parties, despite the mutual use of good faith efforts, are unable to agree upon such terms and conditions within six (6) months of the relevant termination date, the Parties shall appoint an independent valuation expert who shall determine such terms and conditions, which determination shall be binding upon the Parties. If the Parties are unable to agree upon the appointment of such an expert, then each Party shall nominate an expert (the cost of whom shall be borne by such Party), and both experts appointed by the Parties shall jointly appoint the expert who shall make such determination. Any expert appointed pursuant to this Section 15.6(a) shall have at least 15 years’ experience in the business of pharmaceutical development and commercialization. Except as provided above, the costs and expenses of any expert acting under this Section 15.6(a) shall be borne equally by the Parties. Notwithstanding any other provision hereof, in the event that the royalty set pursuant to this Section 15.6(a) is less than that specified in Section 9.9, such reduced royalty shall apply both inside and outside the TOPOTARGET Territory for the relevant Collaboration Product(s).

Notwithstanding the foregoing: (x) in the event of any termination of this Agreement in which CURAGEN loses rights for any Collaboration Product with respect to fewer than all of the countries in the Territory, any rights, licenses and other benefits to be transferred, granted and otherwise assigned to TOPOTARGET as provided above for such Collaboration Product shall be expressly limited to those pertaining to the countries in the Territory to which such termination applies; and (y) at any time prior to any transfer, granting and assignment of rights, licenses and benefits to TOPOTARGET pursuant to this Section 15.6(a), TOPOTARGET may elect, upon notice to CURAGEN, to waive the application of this Section 15.6(a) with respect to such rights, licenses and benefits. Following any such waiver neither Party shall have any obligation or liability to the other with respect to such rights, licenses and benefits.

(b) In the event of any termination of this Agreement by TOPOTARGET pursuant to Section 15.3 or by CURAGEN pursuant to Section 15.4, TOPOTARGET’s license rights pursuant to Sections 7.4 and 7.5 hereof, and its rights pursuant to Section 8.5 hereof, shall continue subject to continued compliance with the relevant terms of this Agreement; and provided that all royalties due to CURAGEN pursuant to Section 9.9 and/or Section 15.6(a) shall thereafter be payable to CURAGEN in accordance with Article 10 unless offsettable against milestones and royalties due with respect to any surviving rights of CURAGEN.

(c) In the event of termination of this Agreement by CURAGEN pursuant to Section 15.3, in addition to any relevant rights provided in Section 15.3(d), TOPOTARGET shall (i) promptly transfer to CURAGEN copies, whether in written or electronic form, of all data, reports, records and materials (including any TOPOTARGET Licensed Technology and/or TOPOTARGET Collaboration Technology necessary to allow CURAGEN to continue to conduct the Research Program and the Development Program all to the extent not previously disclosed to CURAGEN) in TOPOTARGET’s possession or control which relate to the Research Program and/or the Development Program; (ii) return to CURAGEN all relevant records and materials, whether in written or electronic form, in TOPOTARGET’s possession or control containing Confidential Information of CURAGEN, and (iii) furnish to CURAGEN all unused Substances provided to TOPOTARGET by CURAGEN in connection with the Research Program.

15.7 Right to Sell Stock on Hand. CURAGEN shall have the right for one year after any termination or expiration of this Agreement, to dispose of all Collaboration Product then in its inventory and to complete manufacture of and dispose of any work-in-progress then being manufactured, as though this Agreement had not terminated. CURAGEN shall pay royalties thereon, in accordance with the provisions of this Agreement, as though this Agreement had not terminated.

(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 royalties, milestone payments and other monetary obligations that may have accrued hereunder prior to such termination. All of the Parties’ rights and obligations under Sections 4.7, 5.3(e), 5.5, 5.6, 5.7, 6.1, 6.2, 6.3, 6.4(d), 8.3, 8.5 (except in the event of termination by CURAGEN for a payment breach by TOPOTARGET), 8.7, 8.8, 8.9, 9.9, 10, 12, 13 (solely with respect to actions pending at such time), 14, 15.2, 15.5, 15.6, 15.7, 15.8, 17.1 (if in effect at such time), 17.2 (if in effect at such time), 17.4, 17.6, 17.12, 17.15, 17.16 and 17.17 shall survive termination, relinquishment or expiration hereof.

16.1 Events of 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 under 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 shall be 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 by fire, flood, earthquake, explosion or storm; labor disturbances; epidemic; and failure of public utilities or common carriers. In such event TOPOTARGET or CURAGEN, 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 30 days thereafter. To the extent possible, each Party shall use reasonable efforts to minimize the duration of any force majeure.

17.1 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.

(b) Except as provided in Section 17.4(a), neither Party shall be entitled to assign its rights hereunder without the express written consent of the other Party, except that each Party may assign this Agreement to any assignee of all or substantially all of such Party’s business (or that portion thereof to which this Agreement relates) or in the event of such Party’s merger, consolidation or similar transaction.

(c) No assignment contemplated by this Section 17.4 shall be valid or effective unless and until the assignee/transferee shall agree in writing to be bound by the provisions of this Agreement.

17.5 Disclaimer of Warranties.

17.10 Waiver. A waiver by either Party of any of the terms and conditions of this Agreement in any instance shall not be deemed or construed to be a waiver of such term or condition for the future, or of any subsequent breach hereof. All rights, remedies, undertakings, obligations and agreements contained in this Agreement shall be cumulative, and none of them shall be in limitation of any other remedy, right, undertaking, obligation or agreement of either Party.

17.11 Compliance with Law. Nothing in this Agreement shall be deemed to permit a Party to export, re-export or otherwise transfer any Collaboration Product sold under this Agreement without compliance with applicable laws.

The English original of this Agreement shall prevail over any translation hereof.

(b) Without prejudice to the rights and obligations of the Parties under Section 17.15, each Party hereby consents to the in personam jurisdiction of any state or federal court sitting in the State of New York with respect to any matter arising in connection with this Agreement and further consents to the service of any process, notice of motion or other application to any such court or a judge thereof outside the State of New York by registered or certified mail or personal service, provided that reasonable time is allowed for appearance. Each Party hereby waives, to the greatest extent it may do so, any defense it may have on the grounds of inconvenient forum with respect to any action or proceeding maintained in any state or federal court in New York.

(a) Any dispute arising out of or relating to any provisions of this Agreement (a “Dispute”) shall first be referred to the professional mediator for resolution through good faith mediation (“Mediation”) involving the Chief Executive Officers of each respective Party. If the Dispute is not resolved by such individuals within thirty (30) days of written request of either Party for Mediation, then the Dispute shall be resolved as provided in (b) below.

(b) Any Dispute which is not resolved by Mediation as provided in (a) above shall be finally settled by arbitration to be held in New York, New York, under the auspices and then current commercial arbitration rules of the American Arbitration Association (the “AAA”).

[********************************************************************************************************

*********************************************************************************************************

TopoTarget and CuraGen have entered into a collaboration agreement to jointly develop HDAC inhibitors in cancer, as well as potentially other indications. The collaboration will be governed by a global joint steering committee (JSC). This exhibit lays out the principles by which the JSC will manage the clinical development of Collaboration Products.

The goal of the collaboration is submission and registration in major markets of a medically important, competitive Collaboration Product in industry competitive timelines. The initial focus will be in oncology.

The JSC will manage all aspects of development in a manner consistent with this goal. This includes work performed by CuraGen, TopoTarget, or other collaborators (e.g. NCI), as well as all CMC work.

To meet its mandate, it is assumed that the JMC will meet in person once per quarter, and by remote means at all other monthly intervals.

The JSC reviews, approves, measures and manages the global development plan on an ongoing basis. A joint team of TopoTarget and CuraGen employees with appropriate development expertise will develop and implement the plan with appropriate measures by which to measure progress against plan as well as develop contingencies to manage variance to plan. As milestones are reached, this team will analyze data and communicate the implications of the data to the JSC. After initial generation and agreement to a clinical development plan for each Collaboration Product, plans should be reviewed for modification at least once a year, or more frequently if needed, based on emerging clinical data or other environmental changes. In events where it is needed, CuraGen will have the ability to break deadlocks within the JSC.

TopoTarget and CuraGen will jointly develop a global development plan for each Collaboration Product and determine who will be responsible for execution of various parts of the plan. In general, TopoTarget will be responsible for executing development activities in Europe and CuraGen will be responsible for executing development activities elsewhere.

Principles of ICH should be followed including the principle of common technical documentation (CTD). This enables the same material body of information, analyses, and conclusions, as ultimately embodied in the product label, to serve the purposes of registration globally, including specifically the EU and NA.

Both parties will agree on and have the option to participate in venues where external input is sought for development plans (external clinical and/or regulatory consultation). Where feasible, efforts should be made to represent both parties in material external events.

TopoTarget will manage all EU regulatory strategic and operational maters and CuraGen will manage all other regulatory strategic and operational matters – both in a manner consistent with the global development plan.

To foster the goal of efficient clinical development, protocols, data management, and statistical analysis, medical report writing will be harmonized in a way that provides for efficient and consistent product information. This information includes consistency with all ICH dictated terms (AEs, SAEs), inclusion/exclusion criteria, data collection (standard CRF pages wherever possible, a common data base, common edit checks for the data base), common definitions for response rate, partial response, complete response and other efficacy parameters, common uses of oncology toxicity definitions based on accepted norms, common analytical methods and programming, internally consistent conclusions across studies, common study monitoring methodology and study auditing.

Clear mechanisms and responsibilities will be established to meet global requirements for expedited safety reporting, as well as for determining what consequences, if any, reported adverse events have on the risk-benefit of any ongoing clinical trials.

Clear mechanisms and responsibilities will be established to provide a common investigators’ brochure, and updates to it, as well as for IND annual reporting obligations. Whenever possible, these responsibilities will be synchronized as much as possible so that these documents are generated from the same database and data cut-off time, thus supporting consistent analysis and conclusions.

TopoTarget and CuraGen will work jointly with NCI to facilitate NCI’s productive participation in the development program. With this in mind, TopoTarget and CuraGen will work to make sure that as to a much extent as is reasonable, NCI fits the development governance paradigm described above.

Within [********], TopoTarget and CuraGen will agree on a draft global development plan for PXD101. Within [********] thereafter, TopoTarget and CuraGen will meet with external

clinical advisors to review the draft plan, modify it based on their input, and agree to a final development plan.

The final plan will specify the party responsible for executing the planned clinical trials, incorporating the specifics:

TopoTarget will complete an ongoing Phase 1 study of PDX101 in solid tumors (TT20) and initiate and complete a Phase 1 study, followed by a Phase 2 study in [***************(************)].

CuraGen will prepare an IND for US filing, with the objective of commencing Phase 2 trials in [********].

In addition, TopoTarget has signed a LOI for a CRADA with the NCI. Discussions have begun with the NCI in terms of their potential role in exploring alternative dosing schedules and combination therapy. CuraGen will become involved in the CRADA as a third party. As part of the global development plan as governed by the JSC, TopoTarget and CuraGen will determine the optimal utilization of this CRADA from the TopoTarget/CuraGen perspective and jointly represent this to the NCI.
