in Exhibit B; and (f) making selections of Eligible Antigens under Article 5 below. The JMC shall also be responsible for discussing potential Conjugates that are to be utilized in the Research Program; provided, however, that no Conjugate shall be
utilized in the Research Program until the parties have mutually agreed in writing (i) that such Conjugate shall be used in the Research Program, and (ii) those specific one or more Antibodies with which such Conjugate will be utilized. 

 
 3.3 Meetings. The JMC shall meet in person (unless
otherwise agreed on a meeting-by-meeting basis) not less than once each calendar quarter during the term of the Research Program, on such dates and at such times and places as agreed to by CuraGen and ABX, alternating between Fremont, California and
New Haven, Connecticut, or such other locations as the parties mutually agree. For all other meetings, the JMC may meet by telephonic or video conference or in person, as the parties mutually agree. Each party shall have the right to have one (or
such greater number as the parties mutually agree) employee or agent who is not a member of the JMC attend each meeting of the JMC as a non-voting observer. Each party shall be responsible for all its own personnel, travel and related expenses
relating to JMC meetings. The first meeting of the JMC shall take place at the offices of ABX as soon as practicable after the Effective Date, but in no event later than thirty (30) days after the Effective Date. 
  
 3.3.1 Within thirty (30) days following each JMC meeting,
the party hosting the meeting (or entitled to host the meeting, if held by telephonic or video conference or at a location other than Fremont, California or New Haven, Connecticut) shall prepare and provide to the other party mutually acceptable,
reasonably detailed written minutes describing (a) all matters reviewed or considered by the JMC; (b) all discussions regarding potential and actual Antigens; and (c) all determinations and actions of the JMC and the reasons therefor. Such minutes
shall be the Confidential Information of both ABX and CuraGen; provided, however, that to the extent that such minutes relate to the Optioned Antigens and Licensed Antigens of a party they shall be the Confidential Information solely
of such party. 
  
 3.3.2 Not less than ten (10)
days prior to each regularly scheduled quarterly meeting of the JMC, each party shall provide the other party with all data and information, not previously disclosed to the other party, regarding the activities of such party under the Research
Program. 
  
 3.3.3 Not less than five (5) days
prior to each regularly scheduled meeting of the JMC, each party shall provide the other party with a list of the antigens that such party desires to discuss at such JMC meeting for potential use in the Research Program.

 3.4 Actions. ABX and CuraGen each shall be entitled to cast one vote on matters
before the JMC. Decisions of the JMC shall be made by unanimous approval. 
  
 3.5 Disagreements. All disagreements within the JMC shall be resolved in the following manner: 
  
 3.5.1 Promptly upon receipt of written notice (a “Dispute Notice”) from one party to the other of a disagreement to be resolved
under this Paragraph 3.5, the JMC representatives of each party promptly shall present the disagreement to the chief executive officer of such party. 
  
 3.5.2 The chief executive officers of each party thereafter shall meet to discuss each party’s view and to explain the basis for
their respective positions of such disagreement, and in good faith shall attempt to resolve such disagreement among themselves. 
  
 3.5.3 If, within thirty (30) days after receipt of a Dispute Notice as to whether a Research Antigen satisfies the criteria of Exhibit B,
the chief executive officers of each party cannot resolve such disagreement, then upon written notice from one party to the other party, such disagreement shall be settled as follows. Within forty five (45) days after receipt of such Dispute Notice,
the parties shall attempt to mutually agree upon a single independent Third Party arbitrator, who shall be a scientific professional in the antibody field, to resolve such disagreement. If the parties are unable to mutually agree upon one such
person, then each party shall appoint one independent Third Party scientific professional in the antibody field prior to the expiration of such forty five (45) day period, and within sixty (60) days after receipt of such Dispute Notice, such
person(s) shall select a single independent Third Party arbitrator, who shall be a scientific professional in the antibody field, to resolve such disagreement. Each party shall present all information presented to the JMC and all other information
as such party reasonably desires regarding such disagreement. Within ninety (90) days after receipt of such Dispute Notice, such arbitrator shall determine whether such Research Antigen satisfies the criteria of Exhibit B and provide written notice
to the parties regarding such determination. 
  

	 	4.	RESEARCH ANTIGEN IDENTIFICATION AND RESEARCH 

  
 4.1.1 Searches for Research Antigens. During the term of the Research Program, CuraGen shall have primary responsibility for the
screening of the CuraGen Databases and shall conduct searches thereof to identify and recommend to the JMC potential antigens of interest hereunder. CuraGen shall recommend to the JMC [***] antigens of interest (whether or not the genes encoding
such antigens are contained in the CuraGen Databases) that, based on the data and information in the CuraGen Databases and such other data and information as CuraGen may have acquired or developed, (i) CuraGen reasonably believes is not the subject
of any Third Party intellectual property rights (or the parties mutually believe, as evidenced by written agreement, that a license to all applicable Third Party intellectual property rights can be

reasonably obtained), (ii) CuraGen reasonably believes could be subject (or the parties mutually believe, as evidenced by written agreement, that the
antibodies to which could be subject) to a proprietary position of CuraGen, (iii) CuraGen reasonably believes would be available hereunder as a Research Antigen, and (iv) CuraGen reasonably believes is reasonably likely to have potential as a target
for antibody-based therapeutics. In addition, CuraGen will use its best efforts to recommend to the JMC antigens that would have an IP Score (as defined below) of 1, 2, or 3 and not 4 or 5 in a sufficient number to allow selection of at least
[*****] Priority Research Antigens per year from the CuraGen Databases. ABX shall have the right, but not the obligation, to recommend to the JMC antigens of interest from the CuraGen Databases or from other sources that ABX reasonably believes are
not the subject of Third Party intellectual property rights and would be available hereunder as Research Antigens and are reasonably likely to have potential as targets for antibody-based therapeutics. 
  
 4.1.2 Research Antigen Selection. 
  
 During the term of the Research Program, based upon the data and information provided by the
parties regarding potential antigens of interest, the JMC shall select at any JMC meeting, from those antigens proposed by the parties under Section 3.3.3 and 4.1, potential antigens of interest for use in the Research Program. With respect to each
potential antigen which is selected, by the action of the JMC, for use under the Research Program, within thirty (30) days after the date of such JMC meeting, each party shall notify the other party in writing if such party does not have the right
to grant the other party a commercial license under Article 7 below for such antigen. Unless a party timely notifies the other party in writing that it does not have the right to grant the other party a commercial license under Article 7 below for
such antigen, such antigen thereafter shall be a Research Antigen. 
  
 4.1.3 Notwithstanding anything to the contrary in this Agreement, if a party gives written notice to the other party at any time stating that such party does not have the right to grant the other party a commercial
license under Article 7 below for a Research Antigen, then effective thirty (30) days after the receipt by the other party of such notice, such antigen shall cease to be a Research Antigen and both parties shall destroy all Antigen Specific
Materials and Information pertaining to such antigen. A party shall give such written notice to the other party promptly upon the occurrence of the event giving rise to such party’s not having the right to grant the other party a commercial
license under Article 7, to the extent such party has the right to do so. 
  
 4.2 Research Program. 
  
 4.2.1 Research Responsibilities. During the term of the Research Program, each party shall use its commercially reasonable efforts to perform its obligations set forth in the Work Plan within the time schedules
contemplated therein. The JMC may recommend changes to the allocation of responsibilities set forth in Exhibit C, from time to time; provided, however, that such changes shall only be effective if in a written amendment duly executed by both
parties. Other than the activities specified in Exhibit C as being the

Rule 24b-2 under the Securities Exchange Act of 1934.
	
	14

 
responsibility of one party or another, the JMC shall allocate the responsibility for each such activity between the parties, taking into account the skills
of each party, in an effort to divide the resources and internal costs reasonably required to be dedicated by each party to the conduct of such activities [*******************]. In the event that any activities with respect to Research Antigens
(other than CuraGen Exclusive Antigens), other than those specified in Exhibit C as being the responsibility of one party or another, require any payments to a Third Party for goods or services (e.g., specific animal models), such payments shall be
[*******************], provided that all such goods and services and payments therefor are approved by the JMC prior to incurring any such expense. Notwithstanding anything to the contrary in this Agreement, all activities with respect to Research
Antigens that are CuraGen Exclusive Antigens, other than the generation and biochemical characterization of Antibodies as described and allocated to ABX in Exhibit C, shall be the sole and exclusive responsibility of CuraGen, at its sole cost and
expense. With respect to each Research Antigen, during the term of the Research Program, each party may conduct, in its sole discretion, such additional preclinical research in the Research Field as such party reasonably desires to evaluate its
interest in such Research Antigen, provided that, the preceding right shall not apply to ABX in the case of Research Antigens that are CuraGen Exclusive Antigens, and provided further that prior to commencing such additional preclinical research
with respect to Research Antigens that are not CuraGen Exclusive Antigens, such party shall give prior written notice to the other party of the nature and scope of such additional preclinical research regarding such Research Antigen and shall
provide the other party with all results of such research, which research shall be deemed to have been part of the Research Program. Each party shall provide the personnel, materials, equipment and other resources required to conduct its obligations
hereunder; provided, however, that CuraGen shall transfer to ABX all information and materials available to CuraGen that are useful in the conduct of all assays conducted by or on behalf of CuraGen in connection with the Research Program. ABX shall
reimburse CuraGen for all reasonable out-of-pocket expenses incurred in effecting such transfer. CuraGen grants to ABX the nonexclusive, worldwide license (without the right to grant sublicenses) to practice and use all such assays both (a) for use
in the Research Program, and (b) for research purposes (unrelated to the Research Program or CuraGen) related to the research and development of antigens and/or antibodies. Each party shall perform its obligations hereunder in accordance with high
scientific and professional standards, and in compliance in all material respects with the requirements of applicable laws and regulations. Each party shall provide reasonable assistance required by the other party in connection with the performance
of the Research Program. Each party shall have the right, at reasonable times during normal business hours and upon reasonable notice, to visit the facilities of the other party where the other party is conducting its obligations under the Research
Program to observe such activities. 
  
 4.2.2
Research Antigen Work Plans.  
  
 (a) Each
year, the JMC will prioritize up to [****] Research Antigens for immunization based on IP Score (as defined below) and biology (“Priority Research Antigens”). The Parties agree that for purposes of this Agreement, an “IP Score”
for a Research Antigen shall be determined as follows: (i) if CuraGen has priority for the composition of matter for a full length Research Antigen (that is not a variant) such Research Antigen will be accorded a IP 

  

	
	Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential Investment under
Rule 24b-2 under the Securities Exchange Act of 1934.
	
	15

 
Score of 1, (ii) if CuraGen has priority for the composition of matter of a Research Antigen that is a variant and has priority for data demonstrating a
novel method of use for such variant or antibodies thereto such Research Antigen shall be accorded an IP Score of 2, (iii) if the composition of matter of a Research Antigen has been publicly disclosed in the literature (other than the patent
literature, unless such disclosure does not include a disclosure of antibodies) before CuraGen’s priority date and CuraGen has priority for data demonstrating a novel method of use for such variant or antibodies thereto, such Research Antigen
shall be accorded an IP Score of 3, (iv), if the composition of matter of a Research Antigen (or antibodies thereto) has been disclosed in patent literature together with a disclosure of antibodies before CuraGen’s priority date such Research
Antigen shall be accorded an IP Score of 4, and (v) if the composition of matter of a Research Antigen (or antibodies thereto) has been claimed in an issued or granted patent in the patent literature together with a disclosure of antibodies before
CuraGen’s priority date such Research Antigen shall be accorded an IP Score of 5. Unless agreed as provided herein, neither Party shall have any obligation to undertake any work or continue any work with respect to a Research Antigen accorded
an IP Score of 4 or 5 and no Research Antigen accorded an IP Score of 4 or 5 shall be a Priority Research Antigen unless ABX agrees in writing. In the event that CuraGen reasonably believes that, notwithstanding a Research Antigen having an IP Score
of 4 or 5, CuraGen has priority for a substantive method of use for the Research Antigen not previously disclosed in the literature, CuraGen shall have the right to propose such Research Antigen for reconsideration by ABX and if ABX agrees to such
reconsideration, present information demonstrating such method of use and CuraGen’s priority information. Upon a determination by ABX that such a Research Antigen would be acceptable, such Research Antigen shall be accorded an IP Score of
“4-MOU” or “5-MOU”, as the case may be, and may be designated a Priority Research Antigen. From the pool of Priority Research Antigens, ABX will attempt to raise Antibodies by immunization of Xenomouse Animals and the Parties
will attempt to generate and characterize such Antibodies to such Priority Research Antigens. The Parties will use reasonable efforts to analyze or reanalyze, as the case may be, the IP Score of each proposed Priority Research Antigen within ten
(10) business days of its becoming a proposed Priority Research Antigen. If the JMC determines to reimmunize a Xenomouse Animal with a Research Antigen, it will be counted as one of the Priority Research Antigens. 
  
 (b) For each Priority Research Antigen a Work Plan will be
created, including design of the immunogen(s) and specification of all assays required for Eligible Antigen designation pursuant to Exhibit B. For each Research Antigen for which research activities have already begun as of the Revision Date, a Work
Plan will be created that summarizes the work already completed and the work that remains for Eligible Antigen designation pursuant to Exhibit B. In each case, the Work Plan will detail the work to be done or remaining to be done and define the
responsibility of each party in conducting the work under the Work Plan consistent with Section 4.2.2. It is understood and agreed by the Parties that Exhibit C shall serve as a guide for the creation of the Work Plans of each Research Antigen,
however, the Work Plan once created and agreed to by the Parties shall take precedence over Exhibit C with respect to the particular Research Antigen to which the Work Plan applies.

Rule 24b-2 under the Securities Exchange Act of 1934.
	
	16

 (c) Failure by ABX to immunize a Xenomouse Animal within thirty (30) days of delivery of
an immunogen by CuraGen for a Priority Research Antigen meeting the Work Plan criteria for such Priority Research Antigen will result in that Priority Research Antigen being no longer designated as a Research Antigen. ABX will return all CuraGen
Technology and Information to CuraGen related to such Research Antigen and CuraGen will no longer be subject to exclusivity provisions of Section 4.4 with respect to such Research Antigen. 
  
 4.2.3 Neither Party is obligated to perform any further
research on a Research Antigen outside the scope of the agreed upon Work Plan once such Work Plan is completed unless a new Work Plan is agreed to by the JMC. If either Party unreasonably fails to perform an assigned task under a Work Plan after
written request for more than 90 days from the date of the request, unless such delay is due to the failure of the other Party to perform, the other Party can perform it instead and be reimbursed by the originally assigned Party.  

 
 4.2.4 The parties shall [**********] all costs incurred
by ABX for the provision of the Conjugates prior to the selection of an Eligible Antigen by one of the parties including without limitation (a) fees paid by ABX in consideration for the Conjugate in-licensed technology to the extent such fees are
directly related to the use of the Conjugates hereunder and are payable prior to such selection, and (b) costs of scale-up manufacturing of Conjugates incurred by ABX prior to such selection. 
  
 4.2.5 Access. Without limiting the generality of
Section 4.1, each party shall permit up to three (3) employees of the other party access to such party’s facilities, upon reasonable advance notice, at all times during normal business hours during the term of the Research Program Term to work
with the employees of such party in the development and use of assays pursuant to the Research Program. Each party shall provide such employees of the other party in person access to one or more employees of such party skilled in the development and
use of such assays to enable such employees of such other party to utilize such assays and develop similar assays for use in the Research Program and, in the case of ABX, as contemplated under Section 4.2.2; provided, however, except as otherwise
provided in Section 4.2.2, that no license (or sublicense, as the case may be) to any intellectual property relating to such assays is granted hereby, whether expressly or by implication. 
  
 4.2.6 Term of the Research Program. Unless this
Agreement is earlier terminated, the term of the Research Program shall commence on the Effective Date and shall continue through completion of all Work Plans for Research Antigens for which CuraGen has delivered to ABX for immunization on or prior
to June 30, 2005 an immunogen meeting the Work Plan criteria for such Research Antigen (the “Last Immunization Date”). Without limiting the generality of the foregoing, CuraGen will have no obligation to deliver Research Antigens after
June 30, 2005 and ABX will have no obligation to immunize Xenomouse Animals with Research Antigens delivered after June 30, 2005 or conduct any further work with respect to such unimmunized antigens.

 4.2.7 Extended Research. Subject to Sections 6.1.4, 6.1.5, 6.1.6, both parties may
use Antibody Specific Materials and Information and Research Program Technology and Information relating to Research Antigens (i) for which Xenomouse Immunizations were conducted but that failed to become Eligible Antigens, as listed on Exhibit E
and as updated by agreement of the JMC, or (ii) which became Unpicked Eligible Antigens under Section 5.2.12 (“Extended Research Antigens”). At any time during the term of the Extended Research License under Section 6.1.6 (the
“Extended Research License Term”), either party can designate such a Research Antigen as an Optioned Antigen by notice to the other and payment of the Section 8.2.1 fee, provided that a commercial license is available from the other party.
If a commercial license is not available, the Extended Research License shall terminate for such Antigen and each party shall destroy all Antigen Specific Materials and Information related to such antigen. Further, at any time during the Extended
Research License Term, should an antigen subject to the Extended Research License cease to be available for commercial license, the party no longer having the right to grant the exclusive license shall notify the other party and the Extended
Research License shall immediately terminate and each party shall destroy all Antigen Specific Materials and Information related to such antigen.  
  
 4.3 Research Records and Reports. 
  
 4.3.1 Research Records. Each party shall maintain records, in sufficient detail and in good scientific manner appropriate for
patent purposes, which shall be complete and accurate and shall fully and properly reflect all work done and results achieved in the performance of the activities under the Research Program. Each party shall have the right, during normal business
hours and upon reasonable notice, to inspect and copy all such records of the other party to the extent reasonably required for the performance of its obligations under this Agreement. Each party shall maintain such records and the information of
the other party contained therein in confidence in accordance with Article 11 below. 
  
 4.3.2 Research Reports and Information. Each party shall keep the other informed of the progress of its own activities under the
Research Program. At a minimum, within thirty (30) days following the last day of each calendar quarter during the term of the Research Program, each party shall prepare, and provide to the other party, a reasonably detailed written summary report
which shall describe the work performed by such party to date under the Research Program. 
  
 4.4 Exclusivity. 
  
 4.4.1 Except as otherwise expressly permitted under this Agreement, during the term of the Research Program, CuraGen shall not, and shall
not grant any license (or sublicense, as the case may be), immunity or other right to any Person to, research, develop, make, have made, use, import, offer to sell or sell any Antibody Equivalent to [**************(***************)] for use in the
prevention, treatment, detection, diagnosis or monitoring of, or the determination of a predisposition for, or the selection of a particular patient(s) to receive a particular therapeutic treatment(s) for, any disease, state or condition in

humans; provided, however, that the foregoing limitation shall not apply to antigens as to which ABX has notified CuraGen that it does not have the right to
grant CuraGen a commercial license under Article 7 unless ABX has agreed to pay CuraGen the amounts provided hereunder upon the development and commercialization of an antibody product targeting such antigen as if it were an ABX Product hereunder in
return for the licenses from CuraGen for such product as if it were an ABX Product hereunder. Notwithstanding the foregoing, CuraGen shall have the right to research, develop, make, have made, use, import, offer to sell or sell, on its own or with a
Third Party, and to grant a license (or sublicense, as the case may be) to a Third Party to research, develop, make, have made, use, import, offer to sell or sell, an Antibody Equivalent to an antigen for use in the prevention, treatment, detection,
diagnosis or monitoring of, or the determination of a predisposition for, or the selection of a particular patient(s) to receive a particular therapeutic treatment(s) for, any disease, state or condition in humans, (i) pursuant to the
provisions of an agreement set forth in Exhibit D as such agreements are in effect on November 27, 2000 or (ii) if CuraGen does not, in good faith, have the beliefs set forth in clauses (i) and (ii) of the second sentence of Section 4.1 with respect
to an antigen that is not a Research Antigen. Notwithstanding anything to the contrary in Section 4.1, if CuraGen does not, in good faith, have the beliefs set forth in clauses (i) and (ii) of the second sentence of Section 4.1 with respect to a
Research Antigen for which both (i) no Antibodies exist and (ii) immunizations of XenoMouse Animals in attempt to generate Antibodies are not in progress, CuraGen may give written notice thereof to ABX and propose dropping such Research Antigen as a
Research Antigen. If, within thirty (30) days after ABX receives such notice with respect to such Research Antigen, ABX does not give written notice to CuraGen of its consent to designate such Research Antigen as a Priority Research Antigen, then
such Research Antigen shall no longer be a Research Antigen and notwithstanding anything to the contrary in this Section 4.4, (a) CuraGen shall have the right to research, develop, make, have made, use, import, offer to sell or sell, and to grant a
license (or sublicense, as the case may be) to a Third Party to research, develop, make, have made, use, import, offer to sell or sell, an Antibody Equivalent to such former Research Antigen, and (b) ABX will be free to research, develop, make, have
made, use, import, offer to sell or sell, an Antibody Equivalent to such former Research Antigen, provided that ABX shall have no right to use any Confidential Information or patent rights of CuraGen in such activities. 
  
 4.4.2 For a period commencing on November 27, 2000, and
ending on the earlier of (i) the Last Immunization Date, and (ii) the effective date of a termination of the Research Program and the options, licenses and rights of ABX under this Agreement by CuraGen pursuant to Section 14.2.3 upon an uncured
material breach of a material obligation by ABX, CuraGen shall not enter into any agreement (other than permitted license and sublicense agreements hereunder) with any other Person under which: 
  
 (a) CuraGen grants to any other Person rights related to
Antibody Equivalents, if the research concepts to identify antigens used in connection with such agreement are not solely presented by such other Person. 
  

	
	Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential Investment under
Rule 24b-2 under the Securities Exchange Act of 1934.
	
	19

 (b) CuraGen grants to any other Person rights related to Antibody Equivalents, if the
composition of such Antibody Equivalent or the target thereof, or the utility of either, is discovered by CuraGen through CuraGen’s internal research programs. 
  
 (c) CuraGen grants to any other Person rights related to Antibody Equivalents, if such Antibody Equivalent
is identified through access to or use of the CuraGen Databases or the Antibodies. 
  
 (d) CuraGen grants to any other Person actual or effective exclusivity with respect to Antibody Equivalents regarding any prophylactic or
therapeutic field (e.g., cancer, autoimmune disease, inflammation, or cardiovascular disease). For purposes of this provisions, (i) actual exclusivity shall mean that CuraGen cannot conduct material research or development activities to identify new
antigens related to such field for use under the Research Program; and (ii) effective exclusivity shall mean that CuraGen is obligated under such agreement to commit or reserve more than [******] of CuraGen’s capacity to conduct research or
development to identify new antigens related to such field (whether calculated on the basis of CuraGen’s personnel, capital or other resources or the maximum number of antigens deliverable under such agreement). 
  
 (e) CuraGen retains any rights to Antibody Equivalents to
any antigen unless (i) CuraGen retains the right to grant a commercial license under Article 7 below for such antigen (without any reservation of rights to any other Person), (ii) CuraGen discloses such antigen to the JMC as a potential antigen of
interest for use in the Research Program at the first meeting of the JMC following discovery of such antigen, and (iii) such antigen is available for inclusion in the Research Program under this Agreement; provided, however, that conditions (i) and
(iii) shall not apply if CuraGen designates such antigen as a CuraGen Exclusive Antigen at the first meeting of the JMC at which such antigen is presented to the JMC. 
  
 4.4.3 Except as otherwise expressly permitted under this Agreement, for a period ending on the earlier of
(a) the Last Immunization Date, and (b) the effective date of a termination of the Research Program and the options, licenses and rights of ABX under this Agreement by CuraGen pursuant to Section 14.2.3 upon an uncured material breach of a material
obligation by ABX, CuraGen shall not, and shall not grant any license (or sublicense, as the case may be), immunity or other right to any Person to, research, develop, make, have made, use, import, offer to sell or sell any Antibody Equivalent to an
[**********************]. for use in the Commercial Field from and after the date on which a XenoMouse Animal was first immunized with such Antigen; provided, however, that the foregoing limitation shall not apply to antigens as to which ABX has
notified CuraGen that it does not have the right to grant CuraGen a commercial license under Article 7 unless ABX has agreed to pay CuraGen the amounts provided hereunder upon the development and commercialization of an antibody product targeting
such antigen as if it were an ABX Product hereunder in return for the licenses from CuraGen for such product as if it were an ABX Product hereunder. For the avoidance of doubt, nothing in this Agreement shall preclude CuraGen from granting any
license (or sublicense, as the case may be), immunity or other right to any Person to research, develop,

 4.4.4 Except as otherwise expressly permitted under this Agreement, for a period ending on the earlier of (a) the Last Immunization Date,
and (b) the effective date of a termination of the Research Program and the options, licenses and rights of CuraGen under this Agreement by ABX pursuant to Section 14.2.3 upon an uncured material breach of a material obligation by CuraGen, ABX shall
not, and shall not grant any license (or sublicense, as the case may be), immunity or other right to any Person to, research, develop, make, have made, use, import, offer to sell or sell any Antibody Equivalent to an [***************************]
for use in the Commercial Field from and after the date on which a XenoMouse Animal was first immunized with such Antigen. For the avoidance of doubt, nothing in this Agreement shall preclude ABX from granting any license (or sublicense, as the case
may be), immunity or other right to any Person to research, develop, make, have made, use, import, offer to sell or sell any Antibody Equivalent to an [****************************] for any purpose, unless and until a XenoMouse Animal has been
immunized with such Antigen under this Agreement. 
  
 4.4.5 Except as otherwise expressly permitted under this Agreement, during the term of this Agreement, ABX shall not, and shall not grant any license (or sublicense, as the case may be), immunity or other right to any
Person to, research, develop, make, have made, use, import, offer to sell or sell any Antibody Equivalent to a CuraGen Optioned Antigen [***************************], for so long as such antigen remains a CuraGen Exclusive Antigen, CuraGen Optioned
Antigen, or a CuraGen Licensed Antigen [***************************] for use in the Commercial Field. 
  
 4.4.6 Except as otherwise expressly permitted under this Agreement, during the term of this Agreement, CuraGen shall not, and shall not
grant any license (or sublicense, as the case may be), immunity or other right to any Person to, research, develop, make, have made, use, import, offer to sell or sell any Antibody Equivalent to an ABX Optioned Antigen [***************************],
for so long as such antigen remains an ABX Optioned Antigen, or an ABX Licensed Antigen [***************************] for use in the Commercial Field. 
  
 4.5 Research Program Licenses. 
  
 4.5.1 Subject to the terms and conditions of this Agreement, ABX hereby grants to CuraGen a nonexclusive license (or sublicense, as the
case may be) under the Licensed ABX Intellectual Property, without right to grant Sublicenses, in the Research Field solely to conduct its obligations under the Research Program and to conduct additional preclinical research as permitted under

	 	5.	SELECTION OF OPTIONED ANTIGENS 

  
 5.1 Eligible Antigens. Not less than ten (10) days prior to each regularly scheduled meeting of the JMC, each party shall provide
the other party with a dossier for each Research Antigen that it proposes to be considered as a potential Eligible Antigen. Such dossier shall contain all information reasonably available to such party demonstrating whether such Research Antigen
satisfies the criteria set forth in Exhibit B. At such regularly scheduled meeting of the JMC, the JMC shall consider whether such Research Antigen satisfies the criteria set forth in Exhibit B. A Research Antigen shall be an Eligible Antigen at
such time as it is determined to satisfy the criteria set forth in Exhibit B, as determined by the JMC under Section 3.2 above or the arbitrator under Section 3.5 above. Notwithstanding anything to the contrary in this Agreement, if a party gives
written notice to the other party at any time stating that such party does not have the right to grant the other party a commercial license under Article 7 below for an Eligible Antigen, then effective thirty (30) days after the receipt by the other
party of such notice, such antigen shall cease to be an Eligible Antigen and both parties shall destroy all Antigen Specific Materials and Information pertaining to such Eligible Antigen. 
  
 5.2 Selection of Optioned Antigens. During the first
eight (8) years after the Effective Date, each party shall have the right, in its sole discretion, to select Optioned Antigens from the list of Eligible Antigens at the time in question (the “Pool”) as follows: 
  
 5.2.1 CuraGen shall have the right to select
[****************] from the Pool by giving written notice to ABX of such selection. 
  
 5.2.2 After CuraGen has selected [****************], ABX shall have the right to select [***(*)*************] from the Pool by giving
written notice to CuraGen of such selection. 
  
 5.2.3 After ABX has selected [***(*)*************] under Section 5.2.2 or 5.2.4, CuraGen shall have the right to select [***(*)*************] from the Pool by giving written notice to ABX of such selection. 
  
 5.2.4 After CuraGen has selected [***(*)*************] under
Section 5.2.3 above, ABX shall have the right to select [***(*)*************] from the Pool by giving written notice to CuraGen of each such selection. 
  
 5.2.5 A party having then the right to pick an Optioned Antigen may exercise such right at any time and select an Eligible Antigen from
the Pool. 
  
 5.2.6 If CuraGen shall not have
exercised its right to select [******************] pursuant to Section 5.2.1 no later than [****(**)****] after the earlier of (i) determination by the JMC under Section 3.2 above and/or the arbitrator under Section 3.5 above that there are at least
[*****] Eligible Antigens in the Pool or (ii) [****(**)****] after 

  

	
	Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential Investment under
Rule 24b-2 under the Securities Exchange Act of 1934.
	
	25

 
determination by the JMC under Section 3.2 above or the arbitrator under Section 3.5 above of the first Eligible Antigen hereunder, then ABX shall have the
right, exercisable within [****(**)****] after the end of such [****(**)****] period, to select [***(*)**************] from the Pool, as it existed at the commencement of such [****(**)****] period, by giving written notice to CuraGen of such
selection. If ABX shall have exercised such right and made such selection, then such pick shall be deemed to have been ABX’s selection under Section 5.2.2 and the right of CuraGen to select a CuraGen Optioned Antigen pursuant to Section 5.2.1
shall be terminated and its right to select a CuraGen Optioned Antigen pursuant to Section 5.2.3 shall be increased from [***(*)*****(*)] until such time as CuraGen has selected [***(*)*********]. If ABX shall not have exercised such right and made
such selection, then ABX may again exercise such right within [****(**)****] after each time CuraGen fails or refuses to exercise its right to select [*************] pursuant to Section 5.2.1 within [****(**)****] after determination by the JMC
under Section 3.2 above or the arbitrator under Section 3.5 above of the addition of at least [**********(**)***********] to the Pool. 
  
 5.2.7 For each subsequent pick of an Optioned Antigen pursuant to Section 5.2.2, 5.2.3 or 5.2.4, if the party with the right to then pick
(the “picking party”) shall not have exercised its right to select an Optioned Antigen no later than [*****(**)****] after the earlier of (i) determination by the JMC under Section 3.2 above and/or the arbitrator under Section 3.5 above
that there are then at least [******] Eligible Antigens in the Pool at least [****] of which has not been the subject of a prior right of a party to select an Optioned Antigen therefrom or (ii) [***(*)*******] after determination by the JMC under
Section 3.2 above or the arbitrator under Section 3.5 above of the first of the Eligible Antigens added to the Pool which has not been the subject of a prior right of a party to select an Optioned Antigen therefrom, then the non-picking party shall
have the right, exercisable within [******(**)****] after the end of such [******(**)***] period, to select [***(*)*********] from the Pool, as it existed at the commencement of such [******(**)***] period, by giving written notice to the picking
party of such selection. If the non-picking party shall have exercised such right and made such selection, then (i) in the event the picking party is ABX pursuant to Section 5.2.2 or 5.2.4, as the case may be, such selection by CuraGen shall be
deemed to have been a CuraGen selection under Section 5.2.3, ABX shall retain the right to make the next pick and such pick shall be made pursuant to Section 5.2.2 or 5.2.4, as the case may be, ABX’s right to select [*************] pursuant to
such Section shall be [************************************************ ************************************] until such time as ABX has selected [****************************], the right of CuraGen to make its next selection of [*************]
pursuant to Section 5.2.3 (other than deemed selections pursuant to operation of this clause (i)) shall be reduced by [***(*)], and the right of CuraGen to select [*************] pursuant to Section 5.2.3 (other than pursuant to operation of this
Section 5.2.7) shall not be exercisable until such time as ABX has selected [****************] calculated in accordance with this clause (i), and (ii) in the event the picking party is CuraGen pursuant to Section 5.2.3, such selection by ABX shall
be deemed to have been ABX’s selection under Section 5.2.4, CuraGen’s right to select [*****************] pursuant to Section 5.2.3 shall be [************(*)] until such time as CuraGen has selected [********************* ****************]
and the right of ABX to select [*************] pursuant to Section 5.2.4

(other than pursuant to operation of this Section 5.2.7) shall not be exercisable until such time. If the non-picking party shall not have exercised such
right and made such selection, then the non-picking party may again exercise such right within [******(**)****] after each time the picking party fails or refuses to exercise its right to select an Optioned Antigen pursuant to Section 5.2.2, 5.2.3
or 5.2.4, as the case may be, within [******(**)****] after determination by the JMC under Section 3.2 above or the arbitrator under Section 3.5 above of the addition of at least [****(*)***********] to the Pool which has not been the subject of a
prior right of a party to select an Optioned Antigen therefrom. 
  
 5.2.8 It is the intention of the parties that the process for selecting Optioned Antigens under this Section 5.2 shall operate in a manner that preserves CuraGen’s right to select [***(*)**************] for each
[***(*)**************] selected by ABX, and preserves ABX’s right to select [***(*)**************] for each [***(*)**************] selected by CuraGen. 
  
 5.2.9 With respect to each Eligible Antigen which is selected by CuraGen as a CuraGen Optioned Antigen pursuant to this Section 5.2, ABX
shall notify CuraGen in writing, within thirty (30) days of receipt of the notice of selection from CuraGen, if ABX does not have the right to grant CuraGen a commercial license under Article 7 below for such Eligible Antigen. Unless ABX timely
notifies CuraGen in writing that ABX does not have the right to grant CuraGen a commercial license under Article 7 below for such antigen, ABX shall use its good faith efforts to nominate such Eligible Antigen under the XT/ABX Master Research and
License Agreement and to obtain the right thereunder to obtain an XT/ABX Product License Agreement with respect to CuraGen Products to such Eligible Antigen. If ABX is successful in nominating such Eligible Antigen and in obtaining the right to
obtain an XT/ABX Product License Agreement for CuraGen Products to such Eligible Antigen, the ABX shall give prompt written notice to CuraGen. Effective upon such notice, such Eligible Antigen shall be a CuraGen Optioned Antigen. If CuraGen desires
that an Eligible Antigen selected by CuraGen as a CuraGen Optioned Antigen is also designated as a Lambda Optioned Antigen, then CuraGen shall so notify ABX in writing at the time CuraGen selects such Eligible Antigen, and subject to this Section
5.2.9, if such an Eligible Antigen becomes a CuraGen Optioned Antigen it shall also be a Lambda Optioned Antigen hereunder. 
  
 5.2.10 With respect to each Eligible Antigen which is selected by ABX as an ABX Optioned Antigen pursuant to this Section 5.2, CuraGen
shall notify ABX in writing, within thirty (30) days of receipt of the notice of selection from ABX, if CuraGen does not have the right to grant ABX a commercial license under Article 7 below for such Eligible Antigen. Unless CuraGen timely notifies
ABX in writing that CuraGen does not have the right to grant ABX a commercial license under Article 7 below for such antigen, such Eligible Antigen thereafter shall be an ABX Optioned Antigen upon the expiration of such thirty (30) day period.

  
 5.2.11 At such time as an Eligible Antigen
becomes an Optioned Antigen of one of the parties (the “Optioning Party”), the other party shall deliver to the Optioning Party all Antigen Specific Materials and Information in its possession pertaining to such Optioned

Rule 24b-2 under the Securities Exchange Act of 1934.
	
	27

 
Antigen and all related Confidential Information of such other party, and such Antigen Specific Materials and Information and Confidential Information shall
thereafter be the Confidential Information of the Optioning Party. 
  
 5.2.12 Within sixty (60) days after completion of the Research Program Term, the Parties will meet to select any remaining Eligible Antigens in the Pool, with the Party possessing the next pick selecting first, and
then alternating, until all Eligible Antigens are selected or both parties have passed on any remaining Eligible Antigens (“Unpicked Eligible Antigens”). Within thirty (30) days after completion of the Research Program Term, each Party
will advise the other as to whether it has the right to grant the other Party a commercial license under Article 7 for each such remaining Eligible Antigen.

	 	9.	ACCOUNTING AND RECORDS 

  
 9.1 Royalty Reports and Payments. Commencing with the first calendar quarter in which the Royalty Commencement Date for a Product
occurs, CuraGen in the case of CuraGen Products, and ABX in the case of ABX Products (the “Payor”) shall make written reports to the other party (the “Payee”) within sixty (60) days after the end of each calendar quarter, stating
in each such report (a) the number, description, and aggregate Net Sales of such Product sold during the calendar quarter, (b) the calculation of the royalties and other amounts payable under Article 8 above, and (c) otherwise satisfying the royalty
reporting requirements under each ABX In-License applicable to such Product (in the case of CuraGen Products). Concurrently with the making of such reports, the Payor shall pay to the Payee all royalties payable under Article 8 above. With respect
to (1) each CuraGen Product directed to a CuraGen Licensed Antigen and comprising a Lambda Antibody or Genetic Material that encodes such Lambda Antibody, and (2) each CuraGen Product comprising a Conjugate, prior to the date any Third Party royalty
is due for such CuraGen Products pursuant to Section 8.4, ABX shall provide to CuraGen information from the applicable ABX In-License(s) sufficient for CuraGen to calculate the royalty then owing and to satisfy the royalty reporting obligations
under such ABX In-License(s). 
  
 9.2 Records;
Inspection. The Payor shall keep (and cause its Affiliates, Sublicensees and Sublicensees’ Affiliates to keep) complete, true and accurate books of account and records for the purpose of determining the royalties payable to the Payee under
this Agreement. Such books and records shall be kept at the principal place of business of the Payor, its Sublicensee or their respective Affiliates, as the case may be, for at least three years following the end of the calendar quarter to which
they pertain. Such records of the Payor and its Affiliates shall be open for inspection during such three-year period by independent accountants chosen by the Payee, and subject to the approval of the Payor, which approval shall not be unreasonably
withheld or delayed, (which accountants, in the case of ABX, may also represent XT) for the purpose of verifying the royalty statements. The Payor shall require each of its Sublicensees to maintain similar books and records and to open such records
for inspection during the same three-year period by a representative of the Payor reasonably satisfactory to the Payee on behalf of, and as required by, the Payee for the purpose of verifying the royalty statements. All such inspections may be made
no more than once each calendar year at reasonable times mutually agreed by the Payor and the Payee. The independent accountants chosen by the Payee will be obliged to execute a reasonable confidentiality agreement prior to commencing any such
inspection. Inspections conducted under this Section 9.2 shall be at the expense of the Payee, unless a variation or error producing an increase exceeding five percent (5%) of the amount stated for any period is established in the course of any such
inspection, whereupon all costs relating to the audit of such period will be paid by the Payor.

 9.3 Payment Method. All payments by the Payor to the Payee hereunder shall be in
United States Dollars in immediately available funds and shall be made by wire transfer from a United States bank located in the United States to such bank account as designated by the Payee to the Payor. 
  
 9.4 Currency Conversion. If any currency conversion
shall be required in connection with the calculation of royalties hereunder, such conversion shall be made using the selling exchange rate for conversion of the foreign currency into United States Dollars, quoted for current transactions reported
under the heading “Currency Trading – Exchange Rates” in The Wall Street Journal in the United States for the last business day of the calendar quarter to which such payment pertains. If The Wall Street Journal ceases to be published,
then the rate of exchange to be used shall be that reported in such other business publication of national circulation in the United States as the parties reasonably agree. 
  
 9.5 Late Payments. Any payments due from the Payor that are not paid on the date such payments are
due under this Agreement shall bear interest at the lesser of (i) the Prime Rate as reported under the heading “Money Rates” in The Wall Street Journal in the United States on the date such payment is due, plus an additional two
percent (2%), or (ii) the maximum rate permitted by applicable law, in each case calculated on the number of days such payment is delinquent. This Section 9.5 shall in no way limit any other remedies available to any party. If The Wall Street
Journal ceases to be published, then the prime rate to be used shall be that reported in such other business publication of national circulation in the United States as the parties reasonably agree. 
  
 9.6 Withholding Taxes. Each party shall be entitled
to deduct from the royalties owing to the other party hereunder the amount of any withholding taxes, value-added taxes or other taxes, levies or charges with respect to such amounts, other than United States taxes, payable by such party, or any
taxes required to be withheld by such party, to the extent such party pays to the appropriate governmental authority on behalf of the other party such taxes, levies or charges. The withholding party shall use reasonable efforts to minimize any such
taxes, levies or charges required to be withheld on behalf of the other party by such party. The withholding party promptly shall deliver to the other party proof of payment of all such taxes, levies and other charges, together with copies of all
communications from or with such governmental authority with respect thereto, and shall reasonably assist the other party in obtaining a refund thereof (to the extent permitted under applicable law) or to obtain a foreign tax credit therefor.

 10.4 Gene Therapy Applications. Each party’s intention as of the Effective Date is to commercialize a Product hereunder for an
application other than Gene Therapy before commercializing a Product hereunder for a Gene Therapy application. It is understood, however, that either party may or may not also intend to develop and sell Products for use in Gene Therapy, and that
such Gene Therapy application may ultimately be commercialized before a Product is commercialized hereunder for a non-Gene Therapy application. 
  

	 	11.	CONFIDENTIALITY 

  
 11.1 Confidential Information. During the term of this Agreement and for a period of five (5) years following the expiration or
earlier termination hereof, each party shall maintain in confidence the Confidential Information of the other party, and shall not disclose, use or grant the use of the Confidential Information of the other party except on a need-to-know basis to
such party’s directors, officers employees, consultants and collaborators, and to the Third Party licensors of the Licensed Intellectual Property, to the extent such disclosure is reasonably necessary or required in connection with such

date of a research license under Article 6 to an ABX Optioned Antigen, and for so long as such license or a commercial license under Article 7 for such Antigen remains in effect, (i) ABX shall have the right (but not the obligation) to assume
control of the preparation, filing, prosecution and maintenance of the Research Program Patent Rights that specifically and solely claim such ABX Licensed or Optioned Antigen or the use thereof; (ii) ABX shall have the right (but not the obligation)
to assume control of the preparation, filing, prosecution and maintenance of the CuraGen Patent Rights that specifically and solely claim antibodies to such ABX Licensed or Optioned Antigen or the use thereof; (iii) ABX shall reimburse CuraGen on
demand for all previously unreimbursed expenses of the preparation, filing, prosecution and maintenance of such Research Program Patent Rights and CuraGen Patent Rights; and (iv) ABX shall be solely responsible for the expenses of the preparation,
filing, prosecution and maintenance of such Research Program Patent Rights and CuraGen Patent Rights thereafter. In the event there are any Research Program Patent Rights or CuraGen Patent Rights with such claims and other claims, CuraGen shall file
such divisional or other applications, to the extent legally permitted, as may be necessary to separate such claims into a separate application, which ABX shall then have the right to control as aforesaid. If the claims cannot be so separated
CuraGen will take no action with respect to any such claim that would materially narrow the scope thereof without ABX’s express written consent, which consent shall not be unreasonably withheld or delayed. If ABX assumes control of any patent
application pursuant to this Section and determines to abandon such application, ABX shall give written notice of such intention to CuraGen at least thirty (30) days before taking such action, and CuraGen shall have the right, by written notice to
ABX, to assume the prosecution and maintenance thereof. 
  
 (g) CuraGen shall have the right (but not the obligation) to control the preparation, filing, prosecution and maintenance of any Research Program Patent Rights and ABX Patent Rights that specifically and solely claim
any CuraGen Exclusive Antigen or the use thereof or Antibodies that Specifically Bind to such CuraGen Exclusive Antigen or the use thereof. In the event there are any Research Program Patent Rights or ABX Patent Rights with such claims and other
claims, ABX shall file such divisional or other applications, to the extent legally permitted, as may be necessary to separate such claims into a separate application, which CuraGen shall then have the right to control as aforesaid. If the claims
cannot be so separated ABX will take no action with respect to any such claim that would materially narrow the scope thereof without CuraGen’s express written consent, which consent shall not be unreasonably withheld or delayed. 

  
 (h) With respect to each patent application
and patent within the Licensed Intellectual Property Rights or Research Program Patent Rights that specifically and solely claims an Optioned Antigen, a Licensed Antigen, an Antibody that Specifically Binds to an Optioned Antigen, an Antibody to a
Licensed Antigen or the use thereof and with respect to each other patent and patent application within the Research Program Patent Rights owned jointly by

	 	13.	INDEMNIFICATION 

  
 13.1 ABX. ABX shall indemnify and hold harmless CuraGen, and its directors, officers, employees and agents, from and against all
losses, liabilities, damages and expenses, including reasonable attorneys’ fees and costs (collectively, “Liabilities”), resulting from any claims, demands, actions or other proceedings by any Third Party arising from (a) the material
breach of any representation, warranty or covenant by ABX under this Agreement, (b) any use, handling or storage by ABX, its Sublicensees (other than CuraGen) and their respective Affiliates of the CuraGen Technology and Information or the Research
Program Technology and Information, (c) the manufacture, use, sale, handling or storage by ABX, its Sublicensees (other than CuraGen) and their respective Affiliates of ABX Products (without regard to culpable conduct), or (d) any use by ABX, its
Sublicensees (other than CuraGen) and their respective Affiliates of the Confidential Information of CuraGen; provided, however, that ABX shall not be obligated to indemnify or hold harmless CuraGen for such Liabilities to the extent that such
Liabilities arise from the gross negligence or willful misconduct of CuraGen. 
  
 13.2 CuraGen. CuraGen shall indemnify and hold harmless ABX, and its directors, officers, employees and agents, from and against all Liabilities resulting from any claims, demands, actions or other proceedings
by any Third Party arising from (a) the material breach of any representation, warranty or covenant by CuraGen under this Agreement, (b) any use, handling or storage by CuraGen, its Sublicensees (other than ABX) and their respective Affiliates of
the ABX Technology and Information or the Research Program Technology and Information, (c) the manufacture, use, sale, handling or storage by CuraGen, its Sublicensees (other than ABX) and their respective Affiliates of CuraGen Products (without
regard to culpable conduct), or (d) any use by CuraGen, its Sublicensees (other than ABX) and their respective Affiliates of the Confidential Information of ABX; provided, however, that CuraGen shall not be

	55

 
obligated to indemnify or hold harmless ABX for such Liabilities to the extent that such Liabilities arise from the gross negligence or willful misconduct of
ABX. 
  
 13.3 Procedure. If a party (an
“Indemnitee”) intends to claim indemnification under this Article 13, it shall promptly notify the indemnifying party (the “Indemnitor”) in writing of any claim, demand, action or other proceeding for which the Indemnitee intends
to claim such indemnification, and the Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an
Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitor, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential
differing interests between such Indemnitee and any other party represented by such counsel in such proceeding. The indemnity agreement in this Article 13 shall not apply to amounts paid in settlement of any claim, demand, action or other proceeding
if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld or delayed unreasonably. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 13, but the omission so to deliver written notice to the Indemnitor shall not relieve it of any
liability that it may have to any party claiming indemnification otherwise than under this Article 13. The party claiming indemnification under this Article 13, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal
representatives in the investigation of any claim, demand, action or other proceeding covered by this indemnification. 
  
 13.4 Insurance. Each party shall maintain insurance, including product liability insurance, with respect to the research,
development, manufacture and sale of Products hereunder by such party, its Sublicensees and their respective Affiliates in such amount as such party customarily maintains with respect to the research, development, manufacture and sale of its other
products. Each party shall maintain such insurance for so long as such party, its Sublicensees and their respective Affiliates continues to research, develop, manufacture or sell any Products hereunder, and thereafter for so long as such party
customarily maintains insurance covering the research, development, manufacture and sale of its other products. 
  

	 	14.	TERM AND TERMINATION

 14.2.2 If ABX breaches its obligations under Section 8.2,
8.3 or 8.4 above, or materially breaches its obligations under Section 10.2 above, with respect to any Antigen or to ABX Products to any ABX Licensed Antigen, and such breach shall have continued for ten (10) days, in the case of breaches under
Section 8.2, 8.3, or 8.4, or for thirty (30) days, in the case of material breaches under Section 10.2, after written notice of such breach was provided to ABX by CuraGen, CuraGen shall have the right at its option to terminate the licenses (or
sublicenses, as the case may be) under this Agreement with respect to such Antigen or to ABX Products to such ABX Licensed Antigen (as applicable) effective at the end of such ten (10) day or thirty (30) day period, as the case may be, without
otherwise affecting the other licenses (or sublicenses, as the case may be) granted under this Agreement or the other remaining provisions of this Agreement. In the event of such termination by CuraGen, the Antigen which was the subject of the
termination shall be subject to CuraGen’s standby option under Section 7.1.2, ABX’s obligation to provide data and information under Section 7.1.2 shall apply to all data and information in existence at the time of the termination, the
six-month period in which to exercise such option shall commence on the date of termination, and no payment shall be due under Section 8.2.3 upon the exercise by CuraGen of such option. 
  
 14.2.3 If a party shall have materially breached any of its material obligations hereunder (other than under
Sections 8.2, 8.3, 8.4, 10.1 and 10.2 above), and such breach shall have continued for thirty (30) days after written notice of such breach was provided to the breaching party by the nonbreaching party, the nonbreaching party shall have the right
(at its option), effective at the end of such thirty (30) day period, to terminate the Research Program and all options, licenses, and rights to obtain additional options and licenses granted to the breaching party under this Agreement; provided,
however, that any commercial licenses previously granted to the breaching party under Article 7 above (and any related continuing research licenses to the breaching party under Section 6.1 above), all licenses granted to the breaching party under
Section 12.7 above, and all options, licenses, and rights to obtain additional options and licenses granted to the nonbreaching party under this Agreement shall survive any such termination by the nonbreaching party under this Section 14.2.3.

 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. 
  
 1.28 “NIH” shall mean the U.S.
National Institutes of Health. 
  
 1.29 “1934
Act” shall mean the Securities Exchange Act of 1934, as amended, and all regulations promulgated pursuant thereto from time to time. 
  
 1.30 “Party” shall mean TOPOTARGET or CURAGEN and, when used in the plural, shall mean TOPOTARGET and CURAGEN. 
  
 1.31 “Patents” shall mean all letters patent and
patent applications, as well as any and all substitutions, extensions, supplementary protection certificates, renewals, continuations, continuations-in-part, divisions, patents-of-addition and/or reissues thereof. 
  
 1.32 “Person” shall mean any natural person,
corporation, firm, business trust, joint venture, association, organization, company, partnership or other business entity, or any government or any agency or political subdivision thereof. 
  
 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

expenses related to the granting of such license, which payments shall be made within thirty (30) days of receipt of any such consideration. 
  
 3.4 Exclusivity. (a) During the Research Term - For the
duration of the Research Term, CURAGEN shall be TOPOTARGET’s exclusive collaborator for HDAC Inhibitors in the Territory, and CURAGEN therefore agrees that, during the Research Term, CURAGEN and its Affiliates shall not, for the benefit of

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.

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.

Rule 24b-2 under the Securities Exchange Act of 1934.
	
	27

 
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.

 (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

Rule 24b-2 under the Securities Exchange Act of 1934.
	
	39

 (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. 
  
 7.3 Sublicensing by
CURAGEN. 
  
 (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

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. 
  
 7.5 Trademark License. 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

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

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. 
  
 8.7 Adverse Events. 
  
 (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.

 (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. 
  
 9.7 Third Party Royalties. 
  
 (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 [******] 

  

	
	Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential Investment under
Rule 24b-2 under the Securities Exchange Act of 1934.

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:

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 

  

	
	Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential Investment under
Rule 24b-2 under the Securities Exchange Act of 1934.
	
	57

 
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.	PAYMENTS AND REPORTS. 

  
 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 

  

	
	Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential Investment under
Rule 24b-2 under the Securities Exchange Act of 1934.
	
	58

 
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 

  

	
	Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential Investment under
Rule 24b-2 under the Securities Exchange Act of 1934.
	
	59

 
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. 
  

	11.	MANUFACTURING. 

  
 11.1 Manufacturing Responsibility. 
  
 (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 

  

	
	Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential Investment under
Rule 24b-2 under the Securities Exchange Act of 1934.
	
	60

 
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.	CONFIDENTIALITY. 

  
 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

Rule 24b-2 under the Securities Exchange Act of 1934.
	
	62

 
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. 
  

	13.	INTELLECTUAL PROPERTY. 

  
 13.1 Patent Enforcement. 
  
 (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). 
  

	
	Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential Investment under
Rule 24b-2 under the Securities Exchange Act of 1934.
	
	63

 (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. 
  
 13.2
Infringement Actions by Third Parties. 
  
 (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

Rule 24b-2 under the Securities Exchange Act of 1934.
	
	64

 
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).

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.

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).

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

and (ii) the Party making such announcement shall provide the other Party with a copy of the proposed text prior to such announcement sufficiently in advance of the scheduled release of such announcement to afford such other Party a reasonable
opportunity to review and comment upon the proposed text.

 (a) This Agreement shall be governed by and interpreted in
accordance with the laws of the State of New York without regard to its choice of law principles; provided, however, that any arbitration proceeding conducted pursuant to Section 17.15 shall be governed by the Convention on the Recognition
and Enforcement of Foreign Arbitral Awards of June 10, 1958. 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. 
  
 17.15 Arbitration. 
  
 (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

 (c) Neither Section 17.15(a) or (b) shall prohibit a Party from seeking injunctive relief from a court of competent jurisdiction in the event of a breach or prospective breach of Section 3.4 or Articles 6, 7 or 12 of
this Agreement by the other Party which would cause irreparable harm to the first Party.

 EXHIBIT F 

 
 DEVELOPMENT PROGRAM PRINCIPLES 
  
 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. 
  
 Collaboration Goal 
  
 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. 
  
 JSC Governance of Development Program

  
 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. 
  
 Principles
for JSC Management of the Development Program 
  
 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. 
  
 Initial Clinical
Development Program for PXD101 
  
 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.
