(1)  Basis of Presentation and Summary of Significant Accounting Policies
     ---------------------------------------------------------------------

     The unaudited financial statements have been prepared  from the books and
     records of Neurogen Corporation (the "Company") in accordance with
     generally accepted accounting principles for interim financial information
     pursuant to Rule 10-01 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
     management, all adjustments (consisting of normal recurring accruals)
     considered necessary for a fair presentation have been included.  Interim
     results are not necessarily indicative of the results that may be expected
     for the fiscal year.

(2)  Marketable Securities
     ---------------------
 
     Marketable securities consist principally of debt securities with
     maturities of three months to five years and have been classified as
     available for sale securities. Management considers these investments,
     which represent funds available for current operations, an integral
     component of its cash management activities. Accordingly, marketable
     securities have been classified as current assets in the September 30, 1996
     balance sheet.

(3)  Adoption of New Accounting Pronouncements
     -----------------------------------------

     The Company has adopted Statement of Financial Accounting Standards No. 121
     ("SFAS 121"), "Accounting for the Impairment of Long-Lived Assets and for
     Long-Lived Assets to be Disposed Of".  SFAS 121 requires impairment losses
     to be recorded on the long-lived assets used in operations when indicators
     of impairment are present and the undiscounted cash flows estimated to be
     generated by those assets are less than the assets' carrying amount.  SFAS
     121 also addresses the accounting for any expected disposal of long-lived
     assets. The adoption of SFAS 121 had no impact on the financial position or
     results of operations of the Company as no indicators of impairment
     currently exist.

     The Company has adopted the disclosure provisions of Financial Accounting
     Standards No. 123 ("SFAS 123"), Accounting and Disclosure of Stock-Based
     Compensation.  The Company will continue to account for its stock-based
     compensation arrangements under the provisions of APB 25, Accounting for
     Stock Issued to Employees.

 
ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
         FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         Since its inception in September 1987, Neurogen has been engaged in the
     discovery and development of drugs.  The Company has not derived any
     revenue from product sales and, excluding the effect of license fees
     received from Schering-Plough Corporation ("Schering-Plough") in 1995 and
     1996 and Pfizer Inc ("Pfizer") in 1995, expects to incur significant losses
     in most years prior to deriving any product revenues.  Its revenues to date
     have come from three collaborative research agreements entered into with
     Pfizer, one collaboration with Schering-Plough, and from interest income.

     RESULTS OF OPERATIONS
 
         Results of operations may vary from period to period depending on
     numerous factors, including the timing of income earned under existing or
     future strategic alliances, joint ventures or financings, if any, the
     progress of the Company's research and development projects, technological
     advances and determinations as to the commercial potential of proposed
     products.  Neurogen expects research and development costs to increase
     significantly over the next several years as its drug development programs
     progress.  In addition, general and administrative expenses necessary to
     support the expanded research and development activities are expected to
     increase for the foreseeable future.

     THREE MONTHS ENDED SEPTEMBER 30, 1996 AND 1995

         The Company's operating revenues increased to $3.5 million for the
     three months ended September 30, 1996 from $2.6 million for the same period
     in 1995. This increase is due to a $0.9 million increase in research and
     development revenues attributable to the commencement of research funding
     under the Schering-Plough Agreement and the 1995 Pfizer Agreement (as
     defined below). Research and development revenues include amounts received
     from Pfizer and Schering-Plough, under separate collaborations, to fund
     Neurogen's collaborative research programs and, in the case of its NPY-
     obesity collaboration with Pfizer, to reimburse Neurogen for certain
     expenses for the clinical development of the Company's lead anti-obesity
     drug NGD 95-1.

         Research and development costs of $3.6 million were essentially
     unchanged for the three-month period ended September 30, 1996 as compared
     to the same period in 1995. Comparing these periods, an increase in the
     size of the Company's research staff and related laboratory costs was
     generally offset by a decrease in clinical development costs, which
     fluctuate significantly from quarter to quarter. Research and development
     costs represented 81 percent of total operating expenses for the third
     quarter of 1996 as compared to 85 percent for the same period in 1995.

         General and administrative expenses increased 32 percent to $0.9
     million for the three-month period ended September 30, 1996 as compared to
     the same period in 1995. This increase is due to an increased 

 
     level of administrative expenses necessary to support a growing research
     staff.

         Other income consisting primarily of interest income, and gains and
     losses from invested cash and marketable securities increased to $1.3
     million for the third quarter of 1996 from $0.6 million for the same period
     in 1995 due primarily to a higher level of invested funds.

         The Company recognized net income of $0.3 million for the three months
     ended September 30, 1996 as compared with a net loss of $1.0 million for
     the same period in 1995.  The change in earnings is primarily due to the
     increase in interest income due to the higher level of invested funds and
     the increase in research revenues, all as noted above.

     NINE MONTHS ENDED SEPTEMBER 30, 1996 AND 1995

         The Company's operating revenues decreased to $13.7 million for the
     nine months ended September 30, 1996 from $20.4 million for the same period
     in 1995. The Company's 1995 results for the nine months ended September 30,
     1995 include license revenue of $14.0 million received from Schering-Plough
     in 1995 in connection with entering into the Schering-Plough Agreement.
     Results for the nine months ended September 30, 1996 include the
     recognition of a previously unearned license fee of $3.0 million received
     from Schering-Plough in July 1995 for access to a portion of Neurogen's
     combinatorial chemistry libraries. Research and development revenues
     increased $4.3 million, or 68 percent, to $10.7 million due to the
     commencement of research funding under the Schering-Plough Agreement and
     the 1995 Pfizer Agreement. In addition to the quarterly research funding
     payments received from Pfizer, research and development revenue for the
     nine months ended September 30, 1996 includes reimbursements from Pfizer of
     certain development expenses as part of the cost sharing arrangement on the
     NPY obesity project.

         Research and development costs increased 5 percent to $10.0 million for
     the nine-month period ended September 30, 1996 as compared to the same
     period in 1995.   The increase is due to increases in research staff,
     laboratory supplies and increases in external clinical and development work
     on the Company's lead compound for eating disorders, NGD 95-1. Research and
     development costs represented 82 percent of total operating expenses in
     each of the nine month periods ended September 30, 1996 and 1995.

         General and administrative expenses increased 4 percent to $2.3 million
     for the nine months ended September 30, 1996 as compared to the same period
     in 1995, due to an increased level of administrative expenses necessary to
     support a growing research staff.

         Other income, consisting primarily of interest income, and gains and
     losses from invested cash and marketable securities, increased to $3.7
     million for the nine months ended September 30, 1996 from $1.0 million for
     the same period in 1995 due primarily to a higher level of invested funds.

 
         The Company recognized net income of $5.1 million for the nine months
     ended September 30, 1996 as compared with net income of $9.5 million for
     the same period in 1995.  The change in earnings is primarily due to the
     recognition of nonrecurring license fees of $14.0 million in 1995 and $3.0
     million in 1996 and the increase in research and development revenues, all
     as noted above.

     LIQUIDITY AND CAPITAL RESOURCES
 
         At September 30, 1996 and December 31, 1995, cash, cash equivalents and
     marketable securities were in the aggregate $93.9 million and $91.6 million
     respectively.  While the Company's aggregate level of cash, cash
     equivalents and marketable securities did not change significantly during
     the first nine months of 1996, these levels have fluctuated significantly
     in the past and are expected to do so in the future as a result of the
     factors described below.

         Neurogen's cash requirements to date have been met by the proceeds of
     its equity financing activities, nonequity amounts received pursuant to
     collaborative arrangements and interest earned on invested funds. The
     Company's financing activities include three private placement offerings of
     its common stock prior to its initial public offering, underwritten public
     offerings of the Company's common stock in 1989, 1991 and 1995, and three
     private sales of common stock to Pfizer in connection with entering into
     the Pfizer Agreements. Total funding received from these equity financing
     activities was approximately $104.9 million. The Company's expenditures
     have been primarily to fund research and development and general and
     administrative expenses and to construct and equip its research and
     development facility.

         In the first quarter of 1992, the Company and Pfizer entered into a
     collaborative agreement to develop drugs which modulate the
     neurotransmitter gama-aminobutyric acid, or GABA, to treat anxiety
     disorders and cognition impairment (the "1992 Pfizer Agreement") pursuant
     to which Pfizer made a $13.8 million equity investment in the Company.
     Under this agreement, the Company has received or is scheduled to receive
     $4.6 million in each year from 1992 through 1996 to fund Neurogen's
     research in its anxiolytic (anxiety-reducing drugs) and cognitive enhancer
     programs.  Neurogen could also receive milestone payments of up to $12.5
     million during the development and regulatory approval of products from
     these programs.  In return, Pfizer received the exclusive rights to
     manufacture and market collaboration products and for which it will pay
     Neurogen royalties based upon net sales levels, if any, for such products.
     As of September 30, 1996, Pfizer had provided $21.9 million of research
     funding to the Company pursuant to the 1992 Pfizer Agreement, in addition
     to its $13.8 million equity investment in 1992.

         Neurogen and Pfizer entered into their second collaborative agreement
     (the "1994 Pfizer Agreement") in July 1994. Under this agreement, Pfizer
     made an additional $9.9 million equity investment in the Company.
     Additionally, the Company has received or is scheduled to receive
     approximately $7.4 million during the three-year period which commenced
     July 1, 1994, to fund Neurogen's sleep disorder program and may receive up
     to an additional $2.4 million for a fourth year should 

 
     Pfizer exercise its option to extend the research program under the
     collaboration. Neurogen could also receive milestone payments of up to $3.3
     million during the development and regulatory approval of its sleep
     disorder compounds. As part of this second collaboration, Pfizer received
     the exclusive rights to manufacture and market collaboration products for
     which it will pay Neurogen royalties depending upon net sales levels, if
     any. As of September 30, 1996, Pfizer had provided $6.2 million of research
     funding to the Company pursuant to the 1994 Pfizer Agreement (including
     $0.6 million of unearned revenue), in addition to its $9.9 million equity
     investment in 1994.

         Under both the 1992 Pfizer Agreement and the 1994 Pfizer Agreement, in
     addition to making the equity investments and the research and milestone
     payments noted above, Pfizer is responsible for funding the cost of all
     clinical development and the manufacturing and marketing, if any, of drugs
     developed from the collaborations.

         Neurogen and Pfizer entered into their third collaborative agreement
     (the "1995 Pfizer Agreement") in November 1995 to develop drugs which
     modulate the neurotransmitter neuropeptide Y (NPY) to treat disorders,
     including obesity. Under this Agreement, Pfizer made an additional $16.5
     million equity investment in the Company and paid a $3.5 million license
     fee. The Company has received or is scheduled to receive approximately $7.2
     million during the three-year period which commenced November 1, 1995, to
     fund Neurogen's NPY program and may receive up to an additional $2.4
     million per year for a fourth and fifth year should Pfizer exercise its
     option to extend the research program under the collaboration. Neurogen
     could also receive milestone payments of up to approximately $28 million
     during the development and regulatory approval of collaboration products.
     As of September 30, 1996, Pfizer had provided $1.8 million in research
     funding pursuant to the 1995 Pfizer Agreement. As part of this third
     collaboration, Pfizer received the exclusive worldwide rights to
     manufacture and market NPY-based collaboration compounds, subject to
     certain rights retained by Neurogen. In this collaboration, Neurogen will
     fund a minority share of early stage NAFTA clinical development costs.
     Neurogen has retained the right to manufacture any collaboration products
     in NAFTA countries and has retained a profit sharing option with respect to
     product sales in NAFTA countries. If Neurogen exercises the profit sharing
     option, it will fund a minority share of the cost of late stage NAFTA
     clinical development and NAFTA marketing costs and in return receive a
     specified percentage of any profit generated by sales of collaboration
     products in NAFTA countries. If Neurogen chooses not to exercise its 
     profit-sharing option, Pfizer would pay Neurogen royalties on drugs
     marketed in NAFTA countries and would fund a majority of early stage and
     all late stage development and marketing expenses. In either case Neurogen
     would be entitled to royalties on drugs marketed in non-NAFTA countries.

         In June 1995, Neurogen and Schering-Plough entered into an agreement
     (the "Schering-Plough Agreement") to collaborate in the discovery and
     development of drugs for the treatment of schizophrenia and other disorders
     which act through the dopamine family of receptors. Pursuant to the
     Schering-Plough Agreement, the Company received one-time license fees of
     $14.0 million for rights relating to Neurogen's 

 
     dopamine program and $3.0 million for the right to test certain of
     Neurogen's combinatorial chemistry libraries in selected non-CNS assays.
     Schering-Plough funded an additional $3.0 million in 1996 for the right to
     test additional libraries which is included in unearned revenue at
     September 30, 1996. Neurogen expects to receive approximately $7.2 million
     during the two-year period which commenced June 28, 1995, for research and
     development funding of the Company's dopamine program. The Company may
     receive additional research and development funding of up to $3.6 million
     per year for three additional one-year periods depending on whether and the
     extent to which Schering-Plough exercises its right to extend the research
     program under the collaboration. Neurogen could also receive milestone
     payments of up to approximately $32 million if certain development and
     regulatory objectives are achieved regarding its products subject to the
     collaboration. In return, Schering-Plough received the exclusive worldwide
     license to market products subject to the collaboration and Neurogen
     retained the rights to receive royalties based on net sales levels, if any,
     and an option to manufacture products for the United States market. As of
     September 30, 1996, Schering-Plough had provided $5.0 million in research
     funding (including $450,000 in unearned revenue) pursuant to the Schering-
     Plough Agreement. In addition to the payments described above, Schering-
     Plough is responsible for funding the cost of all clinical development and
     marketing, if any, of drugs subject to the collaboration.

         The Company plans to use its cash balance for its research and
     development activities, working capital and general corporate purposes.
     Neurogen anticipates that its current cash balance, as supplemented by
     research funding pursuant to the Pfizer Agreements and the Schering-Plough
     Agreement, will be sufficient to fund its current and planned operations
     through 1999.  However, Neurogen's funding requirements may change and will
     depend upon numerous factors, including but not limited to, the progress of
     the Company's research and development programs, the timing and results of
     preclinical testing and clinical studies, the timing of regulatory
     approvals, technological advances, determinations as to the commercial
     potential of its proposed products, the status of competitive products and
     the ability of the Company to establish and maintain collaborative
     arrangements with others for the purpose of funding certain research and
     development programs, conducting clinical studies, obtaining regulatory
     approvals and, if such approvals are obtained, manufacturing and marketing
     products.  The Company anticipates that it may augment its cash balance
     through financing transactions, including the issuance of debt or equity
     securities and further corporate alliances.  No arrangements have been
     entered into for any future financing and no assurances can be given that
     adequate levels of additional funding can be obtained on favorable terms,
     if at all.

         As of December 31, 1995, the Company had approximately $12,240,000 of
     net operating loss carryforwards available for federal income tax purposes
     which expire from the years 2003 through 2009. The Company had
     approximately $10,670,000 of Connecticut state tax net operating loss
     carryforwards as of December 31, 1995 which expire in the years 1996
     through 1999. Because of "change in ownership" provisions of the Tax 

 
     Reform Act of 1986, the Company's utilization of its net operating loss
     carryforwards may be subject to an annual limitation in future periods.
