     2.1 Formation of Research Committee: Decision Making. Within ten (10)
days after the Effective Date, the Parties shall establish a Research
Committee having a total of four (4) members. The Research Committee shall
have responsibility for strategic oversight of the Research Program and of
implementation thereof.  Gemini and CuraGen each shall select and have the
right to replace up to two (2) representatives to serve as members of the
Research Committee, each of whom shall have senior management
responsibilities for the Party appointing such member. Either Party may
designate a substitute committee member to participate in the event one of
that Party's regular committee members is unable to be present at a meeting.
The Research Committee shall meet, on every two months commencing from its
formation, and from time to time during the term of this Agreement as
otherwise agreed by the Parties. Regular meetings will alternate between New
Haven, Connecticut, U.S.A. and Cambridge, England and any meeting may be held
by teleconference or videoconference upon agreement of both parties. The
Research Committee shall make decisions on the basis of unanimous consensus
after a discussion of the matters as to which decisions are being made. In
the event the Research Committee is unable to agree upon a particular
matter, then such matter shall be submitted for resolution to an executive
officer of each Party for resolution by good faith discussion. If such matter
is not resolved by such officers within thirty (30) days of submission, then
the matter will be submitted to an independent expert in the pharmaceutical
or biotechnology (or other appropriate related) industry acting as an expert
and not as an arbitrator, the identity of whom shall be agreed upon by the
Research Committee (or failing such agreement, by two independent experts,
where one such expert is identified and nominated by


7

<PAGE>

each of the Parties in their respective discretion) who shall resolve the
matter by determining objectively what is the best course of action on a
stand alone basis disregarding the individual subjective needs or preferences
of the Parties. In the absence of manifest error, such determination shall be
conclusive. Such matters are not subject to dispute resolution through
arbitration or litigation under Article 11.

     2.2  CONDUCT OF RESEARCH PROGRAM.  CuraGen shall provide to the Research
Committee not less than *** CuraGen SNPs. Such CuraGen SNPs will be provided
at a rate of at least **** per calendar quarter. Such SNPs will be
accompanied by any Predicted Disease Association and will be prioritized
according to the likely commercial potential of each CuraGen SNP as
reasonably determined by CuraGen, and Gemini shall provide to the Research
Committee a list of human diseases or surrogate clinical parameters therefor.
In addition, Gemini may, but is not obligated to, submit to CuraGen up to
**** Gemini Loci Genes at a rate of no more than *** per calendar quarter,
and CuraGen will search its databases for SNPs in such genes. Any SNPs found
in such searches shall be added to the CuraGen SNPs. Within **** days of the
Effective Date, the Research Committee shall agree upon a Research Program
governing each party's activities under this Agreement. Such Research Program
shall be in writing and shall be approved by the Parties. The Research
Committee shall update the Research Program through the remainder of the
initial term of this Agreement on or before November 1, 2000. Within ****
days of submission of a CuraGen SNP or a Gemini Loci Gene, the Research
Committee shall accept or reject the SNP or gene for inclusion in the
Research Program. As outlined in this Article 2 and subject to the terms and
conditions set forth in this Agreement, CuraGen and Gemini shall conduct the
Research Program to discover Association Discoveries, using DNA samples and
associated clinical information provided by Gemini, for the

purpose of licensing rights in such Association Discoveries to Third Parties
or commercializing such rights themselves. The Research Program shall be
under the direction and supervision of the Research Committee. All work
assignments to be carried out by the Parties shall be subject to Sections 6.1
and 6.2. The Research Committee shall coordinate the Parties' efforts under
the Research Program and facilitate communication between the Parties. In the
event the Research Committee is unable to agree upon a particular matter,
then such matter shall be submitted for resolution to an executive officer of
each Party for resolution by good faith discussion. If such matter is not
resolved by such officers within thirty (30) days of submission, then the
matter will be submitted to an independent expert in the pharmaceutical or
biotechnology (or other appropriate related) industry acting as an expert and
not as an arbitrator, the identity of whom shall be agreed upon by the
Research Committee (or failing such agreement, by two independent experts,
where one such expert is identified and nominated by each of the Parties in
their respective discretion) who shall resolve the matter by determining
objectively what is the best course of action on a stand alone basis
disregarding the individual subjective needs or preferences of the Parties.
In the absence of manifest error, such determination shall be conclusive.
CuraGen and Gemini shall conduct the Research Program in a prudent and
skillful manner and shall comply with all applicable laws, governmental
regulations and guidelines including, without limitation, current NIH
guidelines and any regulations or guidelines pertaining to research with
recombinant DNA.

     2.3  DESIGNATION OF GEMINI TRAITS. As part of the Research Program, the

genotype of the DNA Samples provided pursuant to Section 2.4(a) with respect
to CuraGen SNPs as outlined in the Research Program. The Research Committee
shall determine the scope and time duration for any genotyping activities.
Upon completion of any such genotyping activities, the genotype information
shall be delivered to both Parties.

          (c)  Gemini and CuraGen will collaborate to generate and analyze
clinical and genetic data arising from CuraGen SNPs and Gemini Traits in
order to make Association Discoveries. Both Parties shall have equal access
to all relevant data, including without limitation, SNP Predicted Disease
Association data, genotyping data, physiological data, clinical data and
patient data, and each party will make its data available to the other.

         (d)  CuraGen shall initially bear the cost of genotyping activities
under Section 2.4(a), but shall be reimbursed for **** of such costs by Gemini
as set forth in Section 6.5. Except as set forth in the preceding sentence,
the Parties contemplate that the costs of each Party for activities under
this Section 2.4 will be ******* and the Research Program shall reflect this
****. Any costs incurred in using Third Parties selected by the Research
Committee to perform work pursuant to Section 2.4(b) shall be **** by the
Parties as they are incurred.

    2.5  DETERMINATION OF ASSOCIATES. During the term of the
Research Program and for three (3) months thereafter, either Party may
request that the Research Committee make a determination either; (a) based
upon the genotyping data obtained pursuant to Section 2.4(b) and the analysis
under Section 2.4(c), that a particular CuraGen SNP, whose potential
association with a Gemini Trait has been identified under the Research
Program, is an Association Discovery, or (b) that it is unlikely, to a
reasonable degree of certainty based on the results of the Research Program
and other information available to the Research Committee, that a particular
CuraGen SNP has an association with such Gemini Trait. The Research Committee
shall meet to make the requested determination within thirty (30) days of such
request. If the Research Committee is unable to make a determination, it will
prepare a workplan for additional studies to be conducted by the Parties in
order to allow the requested determination, and the Parties will conduct such
studies as determined by the Research Committee. Upon receiving the results
from the workplan, the Research Committee will reconvene to make the
requested determination. If the Research Committee determines, upon a
particular request, that there is an association between the CuraGen SNP and
the Gemini Trait covered by such request, then the Research Committee will
issue a written notice (an "Association Discovery Notice") signed by at
least one

   Material has been separately filed with the Committee
  -------------------------------------------------------
<PAGE>

Research Committee member from Gemini and one Research Committee member from
CuraGen which specifically identifies the linkage association, and
such linkage association shall thereupon be deemed an Association Discovery.
Alternatively, the Research Committee may make a determination that it is
reasonably clear that there is no association between such CuraGen SNP and
such Gemini Trait (a "Negative Determination"). In the event the Research
Committee is unable to agree upon either an Association Discovery Notice or a
Negative Determination after receiving the results from the workplan, such
matter shall be submitted for resolution to an executive officer of each
Party for resolution by good faith discussion. If such matter is not resolved
by such officers within thirty (30) days of submission, then the matter will
be submitted to an independent expert with expertise in the area of disease
genetics acting as an expert and not as an arbitrator, the identity of whom
shall be agreed upon by the Research Committee (or failing such agreement, by
two such independent experts, where one such expert is identified and
nominated by each of the Parties in their respective discretion) who shall
resolve the matter objectively on a stand alone basis disregarding the
individual subjective needs or preferences of the Parties. In the absence of
manifest error, such determination shall be conclusive. Such matters are not
subject to dispute resolution through arbitration or litigation under Article
11.
    2.6  TRANSFER OF INFORMATION AND MATERIAL. Subject to the provisions of
Article 7, from time to time during the Research Program, each Party shall
provide to the other Party copies of any and all results, information, data
and tangible materials that result from the performance of the Research
Program.

    2.7  USE AND HANDLING OF MATERIALS. All materials transferred by either
party under this Agreement are provided solely for use in conducting the
Research Program and no other

granted under this Agreement.

    5.5 PROSECUTION OF PATENTS WITHIN JOINT TECHNOLOGY.

         (a) With respect to each invention within Joint Technology that
comprises, is based on, or relates to an Association Discovery involving a
Gemini Loci SNP that may be patentable, Gemini shall have the first right,
but not the obligation, of filing, prosecuting and maintaining the Patents
claiming such invention. With respect to each invention in Joint Technology
that comprises, is based on, or relates to an Association Discovery involving
any CuraGen SNP other than a Gemini Loci SNP that may be patentable, CuraGen
shall have the first right, but not the obligation, of filing, prosecuting
and maintaining Patents claiming such invention. The Party with the first
right is referred to in this Article as the "Filing Party." Upon notification
by the Filing Party of an intent to file a patent application claiming Joint
Technology, the other Party ("Other Party") will have fifteen (15) days to
inform the Filing Party whether the Other Party consents to such filing.

         (b) (i) If the Other Party consents to such filing within such
thirty (30) day period, the Filing Party shall reasonably consult with the
Other Party regarding such filing and prosecution efforts, keep the Other
Party reasonably informed of the prosecution (including without
limitation by providing copies of all patent applications, amendments and
correspondence from U.S. and foreign patent offices) so as to allow the Other
Party a reasonable amount of time to review such information, seek the
comments of the Other Party on proposed applications, amendments, and
responses to office actions and reasonably consider such comments of the
Other Party.

17

<PAGE>
              (ii) If the Other Party does not consent within such thirty
(30) day period or the Other Party fails to respond within such period, the
Filing Party shall have the right to proceed with the filing and prosecution
of one or more patent applications for such invention at its own expense and
for its own benefit. If the Filing Party undertakes such filing and
prosecution, the Other Party shall promptly assign all of its right, title
and interest in and to such invention and any intellectual property rights
arising therefrom to the Filing Party, and the Filing Party shall have the
sole right, at its discretion, to commercialize such invention and all
intellectual property rights arising therefrom, without obligation to the
Other Party and free of the requirements of Article 6.

         (c) The Other Party may request that the Filing Party take all
necessary action to file and prosecute a patent application on any particular
invention within the Joint Technology for which the Filing Party has the
first right under Section 5.5(a) and shall provide one hundred twenty (120)
days notice prior to any critical date if possible. Upon such request, the
Filing Party shall have thirty (30) days to inform the Other Party whether or
not the Filing Party will proceed with the requested filing or prosecution.

              (i) If the Filing Party elects within such thirty (30) day
period to proceed, it shall take all commercially reasonable efforts to
accomplish such filing and prosecution and proceed as set forth in Section
5.5(a).

              (ii) If the Filing Party elects within such thirty (30) day
period not to proceed, the Other Party shall have the right to proceed with
the filing and prosecution of one or more patent applications for such
invention at its own expense and for its own benefit. If the Other Party
undertakes such filing and prosecution, the Filing Party shall promptly
assign all of its right, title and interest in and to such invention and any
intellectual property rights arising

18

<PAGE>
therefrom to the Other Party. Thereafter, the Other Party shall have the sole
right, at its discretion, to commercialize such invention and all intellectual
property rights arising therefrom, without obligation to the Filing Party and
free of the requirements of Article 6.

         (d) The Filing Party shall be responsible for paying all costs and
expenses of filing, prosecuting and maintaining the Patents pursued by the
Filing Party under Section 5.5(a) and (b)(i) and Section 5.5(c)(i) above. The
Other Party shall promptly reimburse the Filing Party, based on invoices
submitted at the end of each calendar quarter, for one-half of the actual
out-of-pocket costs and expense incurred by the Filing Party in such filing,
prosecution and maintenance of all such Patents. However, as to any
particular Patent in a country or countries, the Other Party may decline, by
written notice, to pay its share of any such costs and expenses as to such
Patent incurred after receipt of such notice, and upon such notice: (i) the
Other Party shall have no further obligation with respect to such Patent in
such countries; (ii) the Filing Party shall have the right, in its sole
discretion, to continue the prosecution and maintenance of such Patent in the
applicable countries at its own expense and for its own benefit and (iii) the
Other Party shall promptly assign all of its right, title and interest in and
to such Patent in such countries. Thereafter, the Filing Party shall have the
sole right, at its discretion, to commercialize such Patent in such countries,
without obligation to the Other Party and free of the requirements of Article
6 with respect thereto.

    5.6 ASSISTANCE IN PROSECUTION AND MAINTENANCE; EXECUTION OF DOCUMENTS.
Each Party shall reasonably assist the other Party in the filing, prosecution
and maintenance by the other Party (or both Parties jointly, as the case may
be) of Patents under Section 5.5, including, without limitation, executing any
necessary powers of attorney. The Parties shall keep one another informed of
the progress of such prosecution by providing copies of all correspondence

19

<PAGE>
between their patent counsel and the patent offices of the countries where
such applications were filed. Each Party shall promptly execute any documents
or instruments in connection with any assignment of its right, title and
interest in and to any invention within the Joint Technology and intellectual
property rights arising therefrom to the other Party under Section 5.5.

    5.7 INFRINGEMENT OF JOINT PATENTS BY THIRD PARTIES.

         (a) Each Party shall promptly notify the other in writing of any
alleged or threatened infringement of Joint Patents of which it becomes
aware. For all such Joint Patents that are filed under Section 5.5(a) and
(b)(i) or Section 5.5(c)(i), the Parties shall proceed as set forth in
subsections (b) through (e) below with respect to such Third Party
infringement. As to any Joint Patent which is filed under Section 5.5(a)
and (b)(ii) or Section 5.5(c)(ii), the Party that owns such Joint Patent
shall have sole rights, at its sole discretion, to enforce such patent.

         (b) The Filing Party with respect to any such Joint Patent, shall
have the first right, but not the obligation, to bring, at its own expense,
an appropriate action against any person or entity directly or contributorily
infringing a Joint Patent. The Other Party shall cooperate reasonably with
the Filing Party in such action, including consenting to be a named Party to
such action and the furnishing of a power of attorney. The Other Party shall
have the right to participate in any such action against a Third Party
infringer through counsel of its own choice and at its own expense.

         (c) Within ninety (90) days of the discovery of any alleged or
threatened infringement, or receipt of the notice in Section 5.7(a), the
Filing Party shall notify the Other Party whether it intends to institute an
infringement suit or take other reasonable action to protect the relevant
Joint Patent. If the Filing Party elects not to take action, or fails within
such ninety (90) days to so notify the Other Party that it intends to take
action, then the Other Party shall

20



<PAGE>

have the right to institute such suit or take other appropriate action at its
own expense, in its own name, the Filing Party's name, or both.  In such
event, the Filing Party hereby agrees to cooperate reasonably with the Other
Party in any such effort, including by consenting to be a named Party to such
action and the furnishing of a power of attorney.

          (d) In the event that the above provisions of (a) and (b) are not
enforceable under the applicable laws, the Parties shall meet and discuss in
good faith how to respond to the infringement.

          (e) Regardless of which Party brings the action, any recovery
obtained by settlement or otherwise shall be disbursed as follows: (i) when
both Parties participate in the action, the Party bringing such action shall
in the absence of an agreement to the contrary first ensure that any
reasonable expenses incurred in assisting in such action (including counsel
fees) by both Parties are reimbursed, and (ii) thereafter, the net recovery
shall be shared between the Parties according to the * sharing of revenues
that would apply under Section 6.6 if the recovery were Third Party Revenues.
Both parties must consent in advance to any settlement, which consent
shall not be unreasonably withheld.  When only one of the Parties brings
and prosecutes the action, such Party shall retain all recovery.

     5.8 INFRINGEMENT OF THIRD PARTY RIGHTS.

          (a) In the event that any activity of either Party under the
Research Program or a product thereof becomes the subject of a claim for
patent or other proprietary right infringement by a Third Party asserted
against either Party ("Research Program Infringement Claim"), the Parties
shall promptly confer to discuss the claim.

          (b) The Parties shall reasonably cooperate in conducting the
defense of any Research Program Infringement Claim.  The Parties shall share
equally all reasonable costs and

         Confidential Treatment Requested and the Redacted
         Material has been separately filed with the Commission
         ------------------------------------------------------

<PAGE>

expenses of such defense, and both parties must consent to any settlement of
such defense, which consent shall not be unreasonably withheld.

                                   ARTICLE 6

                     COMMERCIALIZATION OF JOINT TECHNOLOGY

     6.1 LICENSING BY PARTIES. The Parties intend to commercialize the Joint
Technology, (except for Patents prosecuted and maintained under Section
5.5(a) and (b)(ii) or Section 5.5(c)(ii) and inventions claimed thereby)
either by commercialization themselves or by granting licenses within
appropriate fields of use to Third Parties to any intellectual property
rights under such Joint Technology (including without limitation all
potential investigative, diagnostic or therapeutic uses thereof) and any
requisite CuraGen Patents and Gemini Patents that would be infringed by the
practice of such Joint Technology but for the grant of such licenses. Gemini
shall have responsibility for implementing and coordinating commercialization
of any Association Discovery involving a Gemini Loci SNP. CuraGen shall have
responsibility for implementing and coordinating commercialization of any
Association Discovery involving any CuraGen SNP other than a Gemini Loci SNP.
The Parties will have joint responsibility for commercializing any other
Joint Technology that either Party requests in writing be commercialized. The
Party (or Parties) with responsibility for commercialization (the
"Commercializing Party") shall take commercially reasonable actions to
achieve commercialization, including without limitation, the preparation of
a plan to achieve the licensing or self commercialization of such Association
Discovery, the marketing of such license rights to such Association
Discovery, the pursuit of commercialization opportunities therefor, and the
negotiation of joint licensing agreements between the Parties and one or more
Third Party licensees for Joint Technology and requisite CuraGen Patents and
Gemini Patents relating


22

<PAGE>

to such Association Discovery. The Commercializing Party shall keep the other
Party reasonably informed about all negotiations and, where reasonable in its
judgement, include the other Party in meetings and negotiations with
prospective licensees. If the Commercializing Party presents a license to the
other Party, the other Party shall be obligated to execute such license,
unless the other Party believes that the license has been negotiated in bad
faith, in which event the matter shall be resolved pursuant to Section 11.4.
The Parties will agree upon procedures and responsibilities for any Joint
Technology for which they have joint responsibility for commercialization.

     6.2 SELF COMMERCIALIZATION. The Commercializing Party may, in the
exercise of its reasonable business judgement, determine to commercialize
itself (in whole or in part) the rights to a particular Association
Discovery. In such event, it will give written notice to the Other Party (a
"Self Commercialization Notice") and the Parties will negotiate in good faith
a Commercialization Agreement pursuant to which (i) the other Party will
grant the Commercializing Party a license to its interest in Joint Technology
and any CuraGen Technology or Gemini Technology (as the case may be)
necessary or useful for development and commercialization of the Association
Discovery, and (ii) the Commercializing Party will pay royalties to the other
Party at a rate that is intended to produce the same net rate for the other
Party ***********************************************************************
*****************************************************************************
*****************************************************************************
************************************************************************** If
the Parties are unable to agree on any terms of such Commercialization
Agreement within ninety (90) days after the Self Commercialization Notice,
the remaining issues shall be submitted for

         Material has been separately filed with the Commission
         ------------------------------------------------------

<PAGE>

resolution to an executive officer of each Party for resolution by good faith
discussion. If such matter is not resolved by such officers within thirty
(30) days of submission, then the matter will be submitted to an independent
expert with expertise and experience in licensing of diagnostic or
therapeutic products (as appropriate), acting as an expert and not as an
arbitrator, the identity of whom shall be agreed upon by the Parties (or
failing such agreement, by two such independent experts, where one such
expert is identified and nominated by each of the Parties in their respective
discretion) who shall resolve the matter by determining commercially
reasonable terms for such Commercialization Agreement consistent with the
principle set forth above, disregarding the individual subjective needs or
preferences of the Parties. In the absence of manifest error, such
determination shall be conclusive.

     6.3 THIRD PARTY LICENSE OBLIGATIONS. In the case of a grant of a license
to a Third Party pursuant to Section 6.1, each Party will grant the
appropriate license to such Third Party under its interest in the Joint
Technology (to the extent that, but for such license, any such Patents or
other rights would be infringed or misappropriated by the exercise of the
development and commercialization rights granted to such Third Party under
the Joint Technology). In addition, with respect to any written agreement
with such Third Party pursuant to Section 6.1, (i) Gemini shall grant to such
Third Party a license under Gemini Patents that would, but for the grant of
such license, be infringed by the exercise of the development and
commercialization rights granted in such agreement to such Third Party under
the Joint Technology, and (ii) CuraGen shall grant to such Third Party a
license under CuraGen Patents that would, but for the grant of such license,
be infringed by the exercise of the development and commercialization rights
granted in such agreement to such Third Party under the Joint Technology.


24

<PAGE>

     6.4 COMMERCIALIZATION COMMITTEE. If the Joint Technology from any
Association Discovery has not been commercialized within two years of the
Association Discovery Notice, the Party that is not the Commercializing Party
may request that further commercialization efforts be the responsibility of a
joint Commercialization Committee. Within thirty (30) days after such
request, the Parties shall establish a Commercialization Committee having a
total of four (4) members. Gemini and CuraGen each shall select and have the
right to replace up to two (2) representatives to serve as members of the
Commercialization Committee, each of whom shall have senior management
responsibilities for the Party appointing such member. Either Party may
designate a substitute for a committee member to participate in the event one
of that Party's regular committee members is unable to be present at a
meeting. The Commercialization Committee shall operate by consensus and shall
seek to make decisions on the basis of consensus after a discussion of the
matters as to which decisions are being made. In the event the
Commercialization Committee is unable to agree upon a particular matter, then
such matter shall be submitted for resolution to an executive officer of each
Party for resolution by good faith discussion. If such matter is not resolved
by such officers within thirty (30) days of submission, and the matter
relates directly to the commercialization of a particular item of Joint
Technology, then the matter will be submitted to an independent expert in the
pharmaceutical (or other appropriate related) industry acting as an expert
and not as an arbitrator, the identity of whom shall be agreed upon by the
Commercialization Committee (or failing such agreement, by the independent
experts, where one such expert is identified and nominated by each of the
Parties in their respective discretion) who shall resolve the matter by
determining objectively what is the best means of commercializing the
applicable Joint Technology on a stand alone basis disregarding the
individual subjective needs or preferences of the Parties. In the absence of

25

<PAGE>

manifest error, such determination shall be conclusive. Such matters are not
subject to dispute resolution through arbitration or litigation under Article
11.

     6.5 REVENUE SHARING. The Parties will share all revenues, including but
not limited to up front license fees, milestone fees and royalty payments
(but not including research funding), received on account of Third Party
licenses granted pursuant to Sections 6.1 and 6.3 ("Third Party Revenues") as
follows:
               The Parties will share the remainder of any such revenues ****
************************************* the Party receiving any such revenues
will promptly give notice of such receipt to the other Party. Within thirty
(30) days of such receipt, shall remit all amounts owing to the other Party
as reimbursement or share of remaining revenue, except that all amounts to be
retained by Gemini or paid by CuraGen to Gemini shall instead be paid to
CuraGen until CuraGen has been reimbursed from such payment for ********** of
the cost of genotype determination work carried out under the Research
Program pursuant to Section 2.4(b)

     6.6 ************************** The Third Party Revenues will be shared

fees, and to grant final, complete, interim, or interlocutory relief.
Notwithstanding the foregoing, however, the Arbitrator may not award any
special, consequential, punitive, incidental or indirect damages arising out
of this Agreement, however caused, under any theory of liability.

existence, the dispute submitted to arbitration, and the Arbitrator's
decision shall be confidential and deemed Confidential Information of each
Party, except as required in connection with the enforcement of such award or
as otherwise required by applicable law, and the Arbitrator shall issue
appropriate protective orders to safeguard such Confidential Information.

               (iii) AUTHORITY OF COURT. Any court having competent
jurisdiction may enter judgment upon any award. The Parties consent to the
jurisdiction of any such Court for the enforcement of these provisions.

during the arbitration to seek and obtain from the appropriate court
