                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                                  (unaudited)


1.  Basis of Presentation

     The accompanying unaudited condensed financial statements have been
     prepared in accordance with generally accepted accounting principles for
     interim financial information and with the instructions to Form 10-Q and
     Article 10 of Regulation S-X. Accordingly, they do not include all of the
     information and footnotes required by generally accepted accounting
     principles for complete financial statements. In the opinion of the
     Company's management, the accompanying unaudited condensed financial
     statements include all adjustments, consisting of only normal recurring
     accruals, necessary to present fairly the financial position, results of
     operations and cash flows of the Company. Interim results are not
     necessarily indicative of the results that may be expected for the entire
     year.

     The accompanying condensed financial statements should be read in
     conjunction with the audited financial statements and notes thereto
     included in the Company's Annual Report on Form 10-K for the year ended
     December 31, 1998.

2.  Roche Collaboration

     The Company signed a life sciences target discovery and pharmacogenomics
     collaboration with F. Hoffmann-La Roche Ltd. and its affiliates,
     Hoffmann-La Roche Inc. and Roche Vitamins Inc. effective March 1999. This
     agreement outlines strategic partnerships with Roche and its affiliates and
     is designed to evaluate existing product candidates, discover new drug
     targets, and facilitate the development of drugs and diagnostic tests for
     the purposes of improving human and animal health.

3. Recently Enacted Pronouncements

     On March 4, 1998, the AICPA issued Statement of Position ("SOP") 98-1,
     "Accounting for Costs of Computer Software Developed or Planned for
     Internal Use". This SOP provides guidance on accounting for the costs of
     computer software developed or obtained for internal use. This SOP requires
     that the following costs be capitalized: 1) external direct costs of
     materials and services incurred in developing or obtaining internal-use
     computer software; 2) payroll and payroll-related costs for employees who
     are directly associated with and devote time to the internal-use software
     project (to the extent of time spent directly on the project); and 3)
     interest costs. Computer software costs that are research and development
     should be expensed as incurred. In addition, training costs should be
     expensed as incurred. This statement is effective for financial statements
     for fiscal years beginning after December 15, 1998, however, earlier
     application is encouraged. The Company adopted this pronouncement effective
     January 1, 1999 with no material effect on its financial position, or
     results of operations.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                        
This Management's Discussion and Analysis of Financial Condition and Results of
Operations as of March 31, 1999 and for the three month periods ended March 31,
1999 and 1998 should be read in conjunction with the sections of the Company's
audited financial statements and notes thereto as well as the Company's
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" that are included in the Company's Annual Report on Form 10-K for
the year ended December 31, 1998.

Overview

CuraGen Corporation (the "Company" or "CuraGen") is a biotechnology company
focusing on the application of genomics to the systematic discovery of genes,
biological pathways and drug candidates in order to accelerate the discovery and
development of the next generation of therapeutic, agricultural and diagnostic
products.  The Company was incorporated in November 1991 and, until March 1993,
was engaged primarily in organizational activities, research and development of
the Company's technology, grant preparation and obtaining financing.  The
Company has incurred losses since inception, principally as a result of research
and development and general and administrative expenses in support of its
operations.  As of March 31, 1999, the Company had an accumulated deficit of
$36,146,435.  The Company anticipates incurring additional losses over at least
the next several years as it expands its internal and collaborative gene
discovery efforts, continues development of its technology and expands its
operations.  The Company expects that losses will fluctuate from quarter to
quarter and that such fluctuations may be substantial.

Results of Operations

Three Months Ended March 31, 1999 and 1998

Revenue.    Revenue for the three months ended March 31, 1999 was $2,671,943, an
increase of $682,371, or 34%, compared to $1,989,572 for the three months ended
March 31, 1998. The increase was largely due to additional collaboration revenue
recorded during the period, under the Company's arrangements with Pioneer Hi-
Bred International, Inc. ("Pioneer") and Glaxo Wellcome, Inc. ("Glaxo"), offset
by a decrease in grant revenue due to the completion of two federal grants
during the first quarter of 1998.  The Company expects future revenues will
continue to increase as additional collaborative arrangements are signed.

Operating Expenses.   Grant research expenses for the three months ended March
31, 1999 of $380,611 represented a decrease of $291,542, or 43%, compared to
$672,153 for the three months ended March 31, 1998.  The decrease in grant
research expenses was primarily attributable to the completion of two federal
grants during the first quarter of 1998, thereby decreasing the costs incurred
by the Company in support of these grants.  As a result of the completion of
various federal grants, the Company foresees a continued decline in grant
research expenses in future periods, unless additional grant awards are
received.

Collaborative research and development expenses for the three months ended March
31, 1999 were $6,591,459, compared to $3,142,553 for the three months ended
March 31, 1998.  The increase of $3,448,906, or 110%, for the three months ended
March 31, 1999 was primarily attributable to the Company's obligation under
existing collaborations to fulfill research requirements, which resulted in
increased purchases of laboratory supplies, increased equipment depreciation and
facilities expenses, and additional personnel costs. Future collaborative
research and development expenses are expected to increase as additional
personnel are hired and research and development facilities are expanded to
accommodate the Company's additional collaborations and internal research.

General and administrative expenses for the three months ended March 31, 1999
increased 133% to $3,209,067 as compared to $1,378,990 for the three months
ended March 31, 1998. The increase was primarily attributable to the expansion
of administration facilities, increased payroll costs and the incurrence of
related depreciation expense and legal expenses in support of developing the
Company's intellectual property portfolios. Over the next several years, the
Company anticipates that percentage increases in general and administrative
expenses will be proportionate to percentage increases in grant research and
collaborative research and development expenses.

Interest Income, Net.  Net interest income for the three months ended March 31,
1999 of $302,267 increased $265,656, or 726%, compared to $36,611 for the first
three months of 1998.  The increase was primarily due to gross interest received
on larger cash and cash equivalent balances held by the Company as a result of
the Company's receipt of proceeds from its initial public offering and
concurrent private placements of securities in March 1998.

Net Loss Attributable to Common Stockholders.   For the three months ended March
31, 1999, the Company reported a net loss attributable to common stockholders of
$7,206,927 or $0.54 per share as compared to $3,675,948 or $0.40 per share in
1998.  Since inception, the Company has incurred operating losses, and as of
March 31, 1999, had an accumulated deficit of $36,146,435 and therefore, has not
paid any federal income taxes.  Realization of deferred tax assets is dependent
on future earnings, if any, the timing and amount of which are uncertain.
Accordingly, valuation allowances in amounts equal to the deferred income tax
assets have been established to reflect these uncertainties in all periods
presented.

Liquidity and Capital Resources

As of March 31, 1999, the Company had approximately $34.0 million in cash and
cash equivalents, compared to approximately $43.0 million as of December 31,
1998.  This decrease represents the utilization of funds for the purchase of
laboratory and office equipment and leasehold improvements, as well as payment
for laboratory facilities, supplies and payroll costs to support internal and
collaborative research processes.  The Company has financed its operations since
inception primarily through its initial public offering of Common Stock, private
placements of equity securities, government grants, collaborative research and
development agreements and capital leases.  As of March 31, 1999, the Company
had recognized $24,109,072 of cumulative sponsored research revenues from
government grants and collaborative research agreements.  To date, inflation has
not had a material effect on the Company's business.

The Company's investing activities have consisted primarily of acquisitions of
equipment and expenditures for leasehold improvements.  At March 31, 1999, the
Company's gross investment in equipment, computers and leasehold improvements
since inception was $24,421,106.  At March 31, 1999, equipment with a gross book
value of $10,853,053 secures the Company's equipment financing facility for
equipment and tenant improvements in support of the laboratory expansions at the
New Haven, Connecticut,  Branford, Connecticut and Alachua, Florida locations.
The Company had a material commitment for capital expenditures of approximately
$1.5 million at March 31, 1999, consisting of machinery and equipment in support
of its SeqCalling(TM) and GeneCalling(R) research processes.

Net cash used in operating activities was $4,749,835 for the three months ended
March 31, 1999, compared to $1,317,701 for the same period ended March 31, 1998.
Cash outflows for the three months ended March 31, 1999 included acquisitions of
property and equipment and payments on capital lease obligations, while cash
inflows primarily included proceeds from common stock option activity.

At March 31, 1999, the Company had federal and Connecticut net operating loss
carryforwards for income tax purposes of approximately $35,400,000. Federal net
operating loss carryforwards expire beginning in 2008, and Connecticut net
operating loss carryforwards began expiring in 1998.  The Company also has
federal and Connecticut research and development tax credit carryforwards for
income tax purposes of approximately $1,900,000 and $2,900,000, respectively at
March 31, 1999.

Year 2000 Compliance

The "Year 2000 Problem" arose because many existing computer programs use only
the last two digits to refer to a year.  Therefore, these computer programs may
recognize a year that ends in "00" as the Year 1900 rather than the Year 2000.
This could result in a significant disruption of operations and an inability to
process certain transactions.

Strategic Plan

Early in 1998, upon going public, the Company assessed its internal computer
systems.  It was determined that, because its computer applications use four
digits to identify a year in the field date, the Company was in fact internally
compliant with Year 2000 requirements.  However, the Company has developed a
strategic plan to estimate the potential risks related to third parties, with
which it has relationships, including third parties that provide non-information
technology systems to the Company.  The third parties include financial
institutions, 

                                       8
<PAGE>
 
vendors, payroll service providers, collaborative partners, utility companies
and granting agencies. If any of these third parties encounter Year 2000
problems, it could potentially have a significant outcome on the ability of the
Company to effectively continue its normal daily operations.

The initial stage, which is still being completed by the Company, has included
distribution of inquiry letters to its most significant third parties, followed
by internal evaluation of the responses received.   As of April 30, 1999,
responses to approximately 75% of the inquiry letters were received.  Several of
those responses require follow-up to obtain further clarification of third party
internal assessments.  During the second quarter of 1999, the Company will
directly contact those third parties that have not yet responded to the inquiry
letters.

Upon learning that certain third parties are not Year 2000 compliant, the
Company may be required to manually process transactions, delay vendor payments,
and/or issue manual checks to employees in place of direct deposits.  These
processes, if necessary, would be a part of the second stage - implementation,
in which the Company would correct and/or replace any vendors or vendor software
that is not Year 2000 compliant, as soon as is feasible.

Costs

There have been no historical costs incurred to date by the Company related to
Year 2000 compliance.  Although the Company originally expected to complete the
initial stage by the end of the first quarter of 1999, due to the delay in
receiving complete responses from third parties, the Company now expects to
complete the initial stage of the Year 2000 Strategic Plan by August 1999.
While the Company cannot predict what impact the Year 2000 problem may have on
third parties, it does not currently believe that it will incur material costs
in the implementation stage of resolving potential Year 2000 problems of third
parties with whom it electronically interacts.

Risks

Once the initial stage of the Company's strategic plan is completed, the Company
will assess the potential risks associated with non-compliance of its external
third parties.  While it is understood by the Company that the potential effect
on results of operations could be serious and could have a material adverse
affect on the Company's business or financial condition, at this time management
has not determined the entire potential level of risk.

Contingency Plan

At the present time, a contingency plan has not been developed.  The Company
will continue to monitor the need for a contingency plan based on the results of
its Year 2000 compliance strategic plan.

Recently Enacted Pronouncements

On March 4, 1998, the AICPA issued Statement of Position ("SOP") 98-1,
"Accounting for Costs of Computer Software Developed or Planned for Internal
Use".  See Note 3 of Notes to Condensed Financial Statements.

expected future levels of losses, potential quarterly fluctuations in the levels
of losses, the expected future increase in revenues and collaborative research
and development expenses, the expected future decrease in grant research
expenses, the anticipated increases in general and administrative expenses, as
well as the Company's Year 2000 readiness.  Such statements are based on
management's current expectations and are subject to a number of factors and
uncertainties that could cause actual results to differ materially from those
described in the forward-looking statements.  The Company cautions investors
that there can be no assurance that actual results or business conditions will
not differ materially from those projected or suggested in such forward-looking
statements as a result of various factors, including, but not limited to, the
following:  the Company's early stage of development, technological uncertainty
and product development risks, uncertainty of additional funding, reliance on
research collaborations, competition, the Company's ability to protect its
patents and proprietary rights and uncertainties relating to commercialization

ARTICLE VI - TREATMENT OF CONFIDENTIAL INFORMATION 

6.00 - Confidential Information

         During the course of the Discovery Collaboration each Party may
disclose to the other proprietary technical and business information. Such
information that is disclosed in writing and marked "Confidential" (or with
words of similar meaning), or which is disclosed orally with a subsequent
written designation of such oral information as confidential, within sixty (60)
days of the oral disclosure, is referred to herein as "Confidential
Information."

         Except as expressly permitted hereunder, the receiving Party shall keep
confidential all Confidential Information of the other Party and will not
disclose such Confidential Information of the other Party to Third Parties by
publication or otherwise. Each Party shall take reasonable steps to ensure that
all of its employees and consultants shall protect and use Confidential
Information of the other Party only in accordance with the terms hereof. Each
Party further agrees not to use Confidential Information of the other Party for
any purpose other than as expressly permitted hereunder. Such obligations of
confidentiality and non-use shall remain in effect for a period of ten (10)
years after the receipt of any such Confidential Information or, in the case of
Confidential Information related to a license granted pursuant to Article VIII
or IX, upon the termination or expiration of the relevant provisions of this
Agreement, whichever event is later. Notwithstanding the foregoing, it is
understood and agreed that the receiving Party's obligations of confidentiality
and nonuse herein shall not apply to any information which:

         (a) is, at the time of disclosure by the disclosing Party hereunder, or
thereafter becomes, a part of the public domain or publicly known or available
through no fault or negligence of the receiving Party or any of its Affiliates;
or

         (b) was otherwise in the receiving Party's lawful possession prior to
disclosure by the disclosing Party, as demonstrated by the receiving Party's
written records relative to such information; or

Affiliates on a non-confidential basis by a third party who is not in violation
of an obligation of confidentiality to the disclosing Party relative to such
information; or

         (d) was required by law to be disclosed; or

         (e) was independently developed by the receiving Party or an Affiliate
without the use of any of the disclosing Party's Confidential Information; or

         (f) is required to be disclosed by a governmental or judicial order.

6.01 - Publications

         It is expected that each Party may wish to publish the results of its
research under this Agreement. Contributions by the other Party shall be
acknowledged in any publication by the publishing Party. In order to safeguard
intellectual property rights, the Party wishing to publish or otherwise publicly
disclose the results of its research hereunder shall first submit a draft of any
proposed manuscript to the appropriate Steering Committee for review, comment
and consideration of appropriate patent application preparation activity at
least sixty (60) days prior to any submission for publication or other public
disclosure. The Steering Committee will advise the Party seeking publication as
to whether a patent application will be prepared and filed or whether trade
secret protection should be pursued. The Steering Committee will, in cooperation
with both Parties, determine the appropriate timing and content of any such
publications. The Steering Committee can, in its discretion, request that the
publishing Party delay publication for up to an additional sixty (60) days for
the purpose of preparation of an appropriate patent application(s). In addition,
any Party can require the deletion of Confidential Information of such Party
from any publication of another Party. 

6.02 - Press Release and Regulatory Filings

         The Parties shall mutually agree on a press release announcing the
execution of this Agreement. Once any written statement is approved for
disclosure by both Parties, either Party may make subsequent public disclosures
of the contents of such statement without the further approval of the other
Party. Nothing in this Agreement shall be 

                                       29
<PAGE>
 
construed to prohibit either party from disclosing factual information or data

Discovery Project Invention, or part thereof, subject to this Article 7.03,
CURAGEN may assume the prosecution of any such patent application at its own
expense; provided, however, that if ROCHE has permanent exclusive rights to such
Discovery Project Invention and permanent exclusive access to the Discovery
Project Data Set from which such Discovery Project Invention arose, then ROCHE
may certify to CURAGEN that ROCHE wishes to maintain such Discovery Project
Invention as a trade secret, in which event CURAGEN shall not have the right to
assume prosecution of such patent application. In case CURAGEN does not wish to
assume the prosecution of any such patent application ROCHE elected to
discontinue, then ROCHE shall be free to abandon or 

                                       31
<PAGE>
 
license or sell such patent application, subject to ROCHE's obligations under
this Agreement.

pertaining primarily to CURAGEN Products. ROCHE agrees to provide reasonable
assistance and cooperation to CURAGEN to facilitate such filing, prosecution and
maintenance. CURAGEN agrees that any such preparation, filing, prosecution and
maintenance shall be conducted diligently and that ROCHE shall be kept fully
informed of the progress thereof and provided with copies of all material
documents pertaining thereto for ROCHE owned Discovery Project Inventions
prosecuted by CURAGEN. 

7.05 - Preventing Loss of Patent Rights

         The Parties shall mutually agree prior to either Party taking any
action which would (a) permit any patent application or patent within the Patent
Rights to lapse; or (b) amend any patent application or patent within the Patent
Rights so as to irrevocably limit or change the lawful scope of such patent
Rights; provided, however, that such obligation shall not apply to any Patent
Rights being prosecuted by one party in which that party has exclusive rights
(either by ownership or license) hereunder. 

7.06 - Conflicting Applications

         In the event a Discovery Project Invention is relevant to both ROCHE
Products and CURAGEN Products, ROCHE will have first and primary responsibility
for seeking patent protection pursuant to Article 7.03, and ROCHE will use
commercially reasonable efforts to seek protection for all CURAGEN Products and
all ROCHE Products in patents claiming such Discovery Project Inventions.

actual or suspected infringement of the Patent Rights by a product that is a
ROCHE Product and CURAGEN shall have the first right (but not the obligation),
at its own expense, to bring suit (or other appropriate legal action) against
any actual or suspected infringement of the Patent Rights by a product that is a
CURAGEN Product. If the Party given the first right does not take such action
with respect to a jointly owned Patent Right within one hundred twenty (120)
days after written notice from the other Party of the infringement, then the
other Party shall have the right (but not the obligation), at its own expense,
to bring suit against such infringement. The Party bringing the suit shall have
the right to settle such suit. Any amount recovered, whether by judgment or
settlement, shall first be applied to reimburse the costs and expenses
(including attorneys' fees) of the Party bringing suit, then to the costs and
expenses (including attorneys fees), if any, of the other Party. Any amounts
remaining shall be allocated to each party in accordance with each Party's
damages incurred on account of such infringement, calculated in accordance with
United States laws pertaining to patent damages.

8.06 - ROCHE Right of First Negotiation for CURAGEN Human Health Products

         During the term of the Discovery Collaboration, in the event that
CURAGEN determines to undertake a program to develop and commercialize for
itself or to license to any Third Party rights to make, use, offer for sale,
sell and import any CURAGEN Human Health Product, CURAGEN shall give written
notice to ROCHE, specifying in reasonable detail the rights CURAGEN intends to
license or the CURAGEN Human Health Product CURAGEN intends to develop (the
"CURAGEN Notice"). ROCHE shall have sixty (60) days after the date of the
CURAGEN Notice to provide a written response to CURAGEN ("ROCHE Response") as to
whether or not it wishes to enter into negotiations with CURAGEN concerning such
CURAGEN Human Health Product. If CURAGEN does not receive a ROCHE Response
within such sixty (60) day period or if ROCHE declines to enter into
negotiations, CURAGEN shall thereafter have the right, alone or in collaboration
with a Third Party, to pursue development, commercialization or 

                                       37
<PAGE>
 
licensing of the rights which were the subject of the CURAGEN Notice, free of
any restriction or limitation, or duty to ROCHE whatsoever other than bonus
payments and royalties payable under Article IX. If the ROCHE Response states
that ROCHE wishes to enter into negotiations with CURAGEN, the parties shall
negotiate in good faith the licensing of such rights to ROCHE for a period of
ninety (90) days from the date of the ROCHE Response.

         If the parties do not agree upon and execute a written agreement for
such rights within such ninety (90) day period, as such period may be extended
by written agreement of both parties, ROCHE shall set forth in writing in detail
its "last best offer" with respect to such licensing of rights. If CURAGEN does
not accept such last best offer, CURAGEN will furnish ROCHE with a written
statement that it rejects such last best offer, and CURAGEN shall thereafter
have the right, alone or in collaboration with a Third Party, to pursue
development, commercialization or licensing of the rights which were the subject
of the CURAGEN Notice, but only on terms reasonably believed by CURAGEN to be
more favorable in the aggregate to CURAGEN than ROCHE's last best offer. 

8.07 - Bonus Payments 

               (i) In addition to the foregoing payments, ROCHE shall also make
                   the following bonus payments to CURAGEN for each ROCHE
                   Product [XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
                   XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
                   XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
                   XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX]

         All such payments shall be made to CURAGEN within thirty (30) days of
the event specified above. For each Animal Nutrition and Health Product which
can be sold in any country without a NADA filing or NADA approval, the bonus
payments required for NADA filing and NADA approval shall be made upon the first
commercial sale of such Animal Nutrition and Health Product in any country.

as of March 31, June 30, September 30, and December 31 and shall be paid within
sixty (60) days after the end of each quarterly period in which such royalties
are earned during the period of time that such royalties are accrued. With each
such quarterly payment, CURAGEN shall receive from ROCHE and/or its Affiliates a
royalty statement setting forth on a country-by-country and ROCHE
Product-by-ROCHE Product basis, the relevant sales information, including at
least the total Net Sales of each ROCHE Product in each country, the calculation
of such Net Sales and the royalty payable to CURAGEN. 

8.10 - Foreign Currency Conversions

bank account designated by CURAGEN, and where appropriate, following receipt by
ROCHE of an invoice for the same from CURAGEN. Whenever for the purpose of
calculating royalties conversion from any foreign currency shall be required,
such conversion shall be made as follows:

         (a) when calculating the Net Sales in each quarter, the amount of such
sales in foreign currencies shall be converted into Swiss Francs as computed in
ROCHE's central Swiss Francs sales statistics for the countries concerned, using
the average monthly rate of exchange at the time for such currencies as
retrieved from the Reuters System.

         (b) when calculating the royalties on Net Sales, such conversion shall
be at the average rate of the Swiss Franc to the United States currency as
retrieved from the Reuters System for the applicable quarter. 

8.11 - Taxes Withheld

         Any income or other tax that ROCHE or any of its Affiliates, Licensees
or Licensors is required by a government agency to withhold and pay on behalf of
CURAGEN with respect to the royalties payable under this Agreement shall be
deducted from and offset against said royalties prior to remittance to CURAGEN;
provided, however, that in regard to any tax so deducted, ROCHE shall give or
cause to be given to CURAGEN such assistance as may reasonably be necessary to
enable CURAGEN to claim exemption therefrom or credit therefor, and in each case
shall furnish CURAGEN proper evidence of the taxes paid on CURAGEN's behalf.

8.12 - License Term Subject to Royalty Payments

         The term of any license granted hereunder ("License Term") pursuant to

         ROCHE, its Affiliates and sublicensees shall keep, for three (3) years
from the date of each payment of royalties, complete and accurate records of
sales by ROCHE and it Affiliates and sublicensees of each ROCHE Product in
sufficient detail to allow the accruing royalties to be determined accurately.
CURAGEN shall have the right for a period of three (3) years after receiving any
report or statement with respect to royalties due and payable to notify ROCHE
that it wishes to conduct an audit.

         At CURAGEN's expense, except as specified below, CURAGEN or its
authorized independent public accountant has the right to engage ROCHE's
independent public accountant to perform, on behalf of CURAGEN or its
independent public accountant, an audit, conducted in accordance with generally
accepted auditing standards in the United States of America, of such books and
records of ROCHE that are deemed necessary by ROCHE's independent public
accountants to report on Net Sales of the product for the period or periods
requested by CURAGEN. Such audit shall not be performed more frequently than
once per calendar year nor more frequently than once with respect to records
covering any specific period of time, upon at least thirty (30) working days'
prior written notice, and shall be conducted during regular business hours in
such a manner as to not unnecessarily interfere with ROCHE's normal business
activities.

         The failure of CURAGEN to request verification of any royalty
calculation during the above-mentioned three (3) year period when records have
to be retained shall be considered acceptance of the accuracy of such reporting.

         In the event that such audit shall indicate that in any calendar year
the royalties which should have been paid by ROCHE are greater than those which
were actually paid by ROCHE, then ROCHE shall promptly pay the underpaid amount
to CURAGEN and, if the royalties which should have been paid are at least five
percent (5%) greater than the amount actually paid, shall also reimburse CURAGEN
for the reasonable cost of such audit. In the event that such audit shall
indicate that in any calendar year the royalties which were actually paid by
ROCHE are greater than those which should have been paid, then CURAGEN shall
promptly reimburse ROCHE with such overpaid amount.

         Any Party may terminate the Discovery Collaboration without cause at
its sole discretion upon six (6) months prior written notice to the other Party;
provided, however, that neither party shall have the right to terminate the
Discovery Collaboration prior to conclusion of the initial two-year term hereof.
For the avoidance of doubt, either RVI or HLR may terminate its participation in
the Discovery Collaboration with no impact on such participation by the other.
In the event that either of HLR or RVI terminates its participation under this
Agreement and the number of CURAGEN FTE's engaged in the Discovery Collaboration
is thereby reduced, the funding hereunder shall be adjusted appropriately.

                                       46
<PAGE>
 
10.01 - Effects of Early Termination Upon Rights of the Parties

         Any termination of the Discovery Collaboration under Article 10.00
shall be without prejudice to the rights of any Party then accruing or otherwise
accrued under this Agreement. Upon any such termination, all remaining ROCHE
Proprietary Materials or CURAGEN Proprietary Materials provided to the other
Party hereunder shall be destroyed or returned to the providing Party, except to
the extent any such materials are subject to a surviving license or right of use
hereunder. CURAGEN shall, in addition, comply with the requirements of Article
10.02. 

10.02 - Post - Termination Access to GeneScape(R)

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX].

10.03 - Termination with Cause

         This Agreement and the licenses granted by one Party to the other
hereunder may be terminated upon any breach by the other Party of any material
obligation or condition, effective thirty (30) days after giving written notice
to the breaching Party of such termination in the case of a payment breach and
sixty (60) days after giving written notice to the breaching Party of such
termination in the case of any other breach, which notice shall describe such
breach in reasonable detail. The foregoing notwithstanding, if the default or
breach is cured or shown to be non-existent within the aforesaid thirty (30) or
sixty (60) day period, the notice shall be deemed automatically withdrawn and of
no effect.

10.04 - Termination Following Bankruptcy

         If either Party files for protection under bankruptcy laws, makes an
assignment for the benefit of creditors, appoints or suffers appointment of a
receiver or trustee over all or substantially all of its property, files a
petition under any bankruptcy or insolvency act or has any such petition filed
against it which is not discharged within sixty (60) days of the filing thereof,
then the other Party may terminate this Agreement by notice to such Party.

10.05 - Termination on Acquisition

         In accordance with the following provisions in this Article 10.05, if
either CURAGEN or ROCHE (the "Acquired Party") shall sell all or substantially
all of its assets in the line of business to which this Agreement pertains or
shall be a party to a merger or consolidation as a result of which shareholders
owning the shares of such party immediately before the transaction do not own a
majority of the shares of the surviving entity in such merger or consolidation
immediately after such transaction (in either case, an "Acquisition"), then the
other Party (the "Non-Acquired Party") shall have the right to terminate this
Agreement in connection with the Acquisition. If either Party expects to be a
party to an Acquisition, to the extent possible such Party shall provide to the
Non-Acquired Party prompt prior written notice of such expected event, together
with such information with respect thereto as the Non-Acquired Party shall
reasonably request, which information the Non-Acquired Party shall request in
writing within 10 days of such written notice. Within 10 days of receipt of such
notice and information, the Non-Acquired Party shall give written notice to the
Acquired Party as to whether or not the Non-Acquired Party intends to terminate
this Agreement in connection with such Acquisition. If the Non-Acquired Party
does not give a written response within such 10 days, or if the Non-Acquired
Party's written response indicates it will not terminate this Agreement in
connection with the Acquisition, then the Non-Acquired Party will have no right
to terminate this Agreement in connection with the Acquisition. If the
Non-Acquired Party's response indicated it intends to terminate this Agreement
in connection with the Acquisition, then the Acquired Party shall notify the
Non-Acquired Party of the effectiveness of the Acquisition and the Non-Acquired
Party shall have the right,

                                       48
<PAGE>
 
exercisable within 10 days after receipt of the Acquired Party's notice to the
Non-Acquired Party of the effectiveness of such Acquisition, to immediately
terminate this Agreement. Any Discovery Project in progress at the time of
termination shall be completed. Any termination under this Article 10.05 shall
be without liability or any further obligation of either party. All licenses
granted hereunder (and the corresponding royalty and milestone obligations)
shall survive termination under this Article 10.05.

10.06 - Effect of Termination under Article 10.03

         Upon termination of this Agreement under Article 10.03 by a Party, all
relevant licenses granted by the terminating Party to the breaching Party
hereunder shall terminate automatically. In addition, upon any termination
pursuant to Article 10.03, the breaching Party shall be deemed without any
further action to have forfeited its rights to further access the Discovery
Project Data Sets or to utilize any Target or Optimization Panel. 

10.07 - Obligations

         All Parties shall remain liable for all obligations accruing prior 
to the date of termination.

10.08 - Remedies

         If either Party shall fail to perform or observe its material
obligations, or otherwise breaches any of its material obligations under this
Agreement, in addition to any right to terminate this Agreement, the
non-defaulting Party shall have the right to any other relief or remedies
available under law or equity. 

10.09 - Surviving Provisions

         Notwithstanding any provision herein to the contrary, the rights and
obligations set forth in Article VI hereof, as well as in Articles 4.00, 4.01
and Articles VII, VIII, IX, X and XI, shall survive the normal expiration, early
termination or termination upon Acquisition of this Agreement; provided,
however, that if this Agreement is terminated due to breach by ROCHE, ROCHE
shall have no continuing rights under Article 4.00 or Article VIII, and if this
Agreement is terminated due to breach by CURAGEN, CURAGEN shall have no
continuing rights under Article 4.01 or Article IX.

illegal by any court of competent jurisdiction or are deemed unenforceable under
then current applicable law from time to time in effecting during the Term
hereof, it is the intention of the Parties that the remainder of this Agreement
shall not be affected thereby provided that a Party's rights under this
