                                     PART I
 
ITEM 1.  BUSINESS
 
     Oncogene Science, Inc., a leader in the innovation of drug discovery
technologies, combines genetically engineered live-cell assays with high
throughput robotic screening to discover novel, small molecule pharmaceuticals.
Independently and in collaboration with Pfizer Inc. ("Pfizer"), Hoechst Marion
Roussel, Inc. ("HMRI"), Wyeth-Ayerst Laboratories Division of American Home
Products Corporation ("Wyeth") and Ciba-Geigy, Ltd. ("Ciba"), the Company is
engaged in the discovery and development of drugs for 30 target proteins in a
wide range of disease areas, including cancer, atherosclerosis, neurological
disorders and chronic anemias.
 
BACKGROUND
 
     Since the early 1980s, major advances in molecular biology have increased
the scientific understanding of the complex regulatory and functional mechanisms
that operate within the cell. Among these advances is the ability to isolate and
manipulate the key genetic molecules DNA and RNA. Genes are composed of segments
of DNA, which are located within the cell nucleus. Each gene contains the
chemical information required for the production of a single protein. Generally,
10,000 to 20,000 of the 100,000 genes contained in a human cell are actively
involved in the production of proteins specific to that cell.
 
     Proteins are molecules that either regulate or perform most of the
physiological and structural functions of the body. Abnormalities in the
cellular production or activity of proteins are the causes of many diseases.
Most drugs work by binding to specific proteins to change their activity
resulting in a therapeutic effect on the disease associated with that protein.
 
     Gene transcription is a key step in the production of proteins by the cell.
Gene transcription occurs when a segment of DNA containing the coding sequence
for an individual protein is copied into an intermediate template called
messenger-RNA ("mRNA"). The DNA within a gene is divided into at least two types
of sequences. Certain types of sequences encode the structural information for
mRNA, while other sequences, called response elements, regulate the production
of mRNA. Certain intra-cellular proteins, known as transcription factors,
interact with response elements to regulate the production of mRNA and,
therefore, the production of the corresponding protein. The conversion of mRNA
into its corresponding protein takes place in a process called translation.
 
     Changes in gene transcription occur in response to a wide variety of
signals. Complex interactions between transcription factors and response
elements control the rate with which gene transcription is carried out in
response to these signals. The process by which the information contained in
these signals is transmitted into the nucleus is called signal transduction.
Activation of gene transcription increases the levels of a protein while
inhibition of gene transcription decreases production of a protein.
 
     TRADITIONAL DRUG DISCOVERY
 
     The traditional discovery method for small molecule pharmaceuticals
involves the random testing of thousands of compounds in drug screens. These in
vitro tests or assays typically employ single proteins, such as receptors, as
targets for discovery of drug candidates. For each drug screen, the target
protein is selected because the scientist believes a compound that binds with
this target may have a therapeutic benefit with respect to the disease under
study. Lead compounds or "hits" are defined as compounds that bind to target
protein and either inhibit or stimulate its activity. Medicinal chemists then
focus on optimizing these initial lead compounds to improve potency and
specificity. Nearly all drugs sold today (with the exception of recombinant
proteins) were either discovered in drug screens or are derived from the lead
compounds identified in such screens.
 
     The simplified drug screens used in traditional drug discovery employ
isolated components of the cell and are an inadequate representation of the
complex, physiological environment that exists within living cells. Receptors,
signal transduction proteins and transcription factors, which are targets for
therapeutic interven-
 
                                        2
   3
 
tion, do not exist in isolation in the cell, but rather occur as large complexes
of multiple proteins bound together with specific structures. Lead compounds
identified in the artificial environment of traditional drug screens are
frequently found to be either ineffective or toxic in live cells, because these
complex intra-cellular interactions are not reproduced in conventional in vitro
screens. Consequently, drug companies often devote substantial resources to
optimizing a traditional drug screen lead compound that will be found to be
ineffective in the more complex environment of live cells.
 
     A further limitation of traditional drug discovery is that many of the
major diseases, such as many types of cancer, atherosclerosis and diabetes, are
due to mutations or abnormalities in more than one protein, many of which remain
unknown. Consequently, the classical drug discovery paradigm of targeting a
single protein in a drug screen has met with only limited success in identifying
drugs for treatment of such complex diseases.
 
     In addition, slow and labor intensive traditional screening methods have
limited the number and chemical diversity of the compounds that can be tested in
assays. Traditional drug screens, carried out manually by scientists working at
the bench, or by using limited automation, typically evaluate less than 10,000
test compounds per year against each target protein. Even though many millions
of distinct chemical structures exist, with this approach it is not unusual for
screening to be terminated at the end of several years with no lead compounds
identified, after examining only a small fraction of available compounds. This
limitation of speed and scale often restricts both the quality and quantity of
lead compounds available for further testing and development and hinders drug
discovery.
 
     The rising costs of health care and changes in health care management
policies are applying increasing competitive pressure on the pharmaceutical
industry, leading to an emphasis on the cost-effectiveness and quality of drug
candidates and the speed with which novel classes of pharmaceuticals can be
brought to the marketplace. In this environment, new discovery technologies that
improve the number and quality of lead compounds have become critical in order
to identify novel drug candidates and to conduct cost-effective clinical
development.
 
ONCOGENE SCIENCE'S TECHNOLOGY PLATFORM
 
     The Company's technologies have been designed to solve many of the
limitations associated with conventional drug screens. The Company's technology
platform consists of applying its understanding of the molecular biology of gene
transcription to the development of proprietary live-cell assays. These assays
are used to test diverse compounds derived from natural sources and from
medicinal chemistry libraries of its collaborative partners using automated,
high throughput robotic drug screening techniques. In addition, the Company is
expanding its capabilities in combinatorial chemistry. The Company believes its
technology platform is widely applicable to the identification of drug
candidates to treat many different diseases, including diseases due to mutations
or abnormalities in multiple genes. Utilizing its technology, the Company has
been able to identify lead compounds that it believes are potent and selective,
possess minimal or no cellular toxicity and have activity in live cells.
 
  LIVE-CELL ASSAYS AND GENE TRANSCRIPTION
 
     The Company's drug screens utilize live cells that express proteins
believed to be associated with a particular disease. For any one target protein,
there are multiple sites within the cell where a drug can act to exert a
specific effect. Cell-based screens, therefore, provide multiple sites of
therapeutic intervention, such as receptors, signal transduction proteins and
transcription factors, which the Company believes increases the probability of
finding promising lead compounds. Furthermore, live-cell assays provide data on
the cytotoxicity and specificity of the compounds tested, allowing the Company
to define key properties of a lead compound earlier in the development process.
Therefore, the Company believes that its drug discovery technology fosters the
generation of high quality leads that are more likely to progress through
preclinical studies compared to lead compounds identified by traditional
methods.
 
     The Company believes its live-cell assays are effective in identifying
compounds that exert a therapeutic effect by altering transcription of
particular target genes. Gene transcription-based drugs act by increasing or
decreasing the amount of mRNA and, therefore, the amount of the corresponding
protein associated with a
 
                                        3
   4
 
particular disease. It has been demonstrated in recent years that a number of
widely used drugs exert their primary clinical effect through a gene
transcription-based mechanism. These include oral contraceptives, tamoxifan for
breast cancer, cyclosporin A for immunosuppression (used in tissue
transplantation), retinoids for dermatology, and aspirin. These drugs were
discovered and developed prior to an understanding of gene transcription. Now
that gene transcription is better understood, the Company believes its gene
transcription technology is an important mechanism for therapeutic intervention
and a process through which drug discovery assays can be designed.
 
     In order to measure production of the target protein produced by gene
transcription in the cell, Oncogene Science's live-cell assays utilize a
reporter gene, luciferase. Luciferase is the molecule that causes fireflies to
illuminate and is the source of one of nature's most sensitive chemilumiscent
reactions. The Company genetically engineers the luciferase gene into the
regulatory framework of the gene of interest to create a live cell line, where
the amount of light produced by luciferase corresponds to the level of the
target protein produced by the gene of interest. These cell lines are then
employed in screens for small molecule test compounds that affect expression of
the reporter gene. Lead compounds are readily identified by changes in the
amount of light produced by the tester cell line. Compounds that show activity
on the reporter gene in the specific cell line are then further tested to
confirm their activity on the target gene.
 
  HIGH THROUGHPUT ROBOTIC SCREENING TECHNOLOGY
 
     Since 1988, Oncogene Science has been a pioneer in the development of high
throughput screening. High throughput screening is the practice of rapidly
testing hundreds of thousands of test compounds against a target protein, and
has become a major focus of leading pharmaceutical companies over the last few
years. Competitive pressures in the pharmaceutical industry are requiring
pharmaceutical companies to find ways to identify quality drug candidates more
quickly and cost effectively. The Company believes that worldwide efforts to map
and sequence the human genome will result in the identification of increasing
numbers of new target genes. Moreover, new technologies, such as combinatorial
chemistry, may generate tens of millions of new compounds to test in in vitro
and live-cell assays.
 
     The Company has developed proprietary hardware and software systems to
automate the entire drug screening process, from the addition of the test
substances to the cells to the analysis of the data generated from the tests. In
its proprietary robotic screening facility, the Company can analyze up to
300,000 different test samples each week, depending on the complexity of the
assays. The Company's robotic systems are not limited to any particular assay
format and can be reconfigured to run a wide variety of assays. In addition to
transcription-based, live-cell assays, the Company's robotic systems can perform
conventional in vitro assays and live-cell assays not focusing on gene
transcription.
 
     In designing drug screens, the Company generally selects the most relevant
human cell line for the target protein. For example, liver cells are used in
assays designed to test for the production of proteins normally produced in the
liver. In order to confirm results obtained in these cell lines, the Company
subjects lead compounds to assays using primary cells isolated from fresh
tissues, which it believes are the most accurate cell types to predict the
activity of the test compounds. Traditionally, these primary cell assays have
not been used in high throughput screens because the sensitivity of the cells to
small changes in temperature, humidity and carbon dioxide levels make accurate
quantitative data difficult to obtain. The Company has developed proprietary
environmental control chambers to tightly regulate these conditions and allow
the use of primary cells in high throughput screens. While the Company often
focuses on transcription-based screens, it has the ability to perform an
extensive portfolio of different screens depending on the targeted disease
indication.
 
  DIVERSE COMPOUND LIBRARIES AND COMBINATORIAL CHEMISTRY
 
     Access to large libraries of diverse compounds is an important aspect of
the Company's drug discovery efforts. The Company's collaborative partners have
provided large compound libraries to the Company pursuant to its collaborative
research programs. Certain collaborative partners have made their compound
libraries available for additional research by the Company outside the existing
collaborative programs. The Company has developed robotic systems to format
compound libraries into microtiter plates for high
 
                                        4
   5
 
throughput screening and an advanced inventory control process incorporating a
bar code system to track these compounds. The Company has prepared and archived
several distinct medicinal compound libraries belonging to the Company's
pharmaceutical partners for screening applications. In excess of 700,000 samples
are archived at the Company and over 150,000 of these can be made available to
the Company's proprietary discovery programs. For any compound from the
Company's collaborative partners' libraries that emerges as a lead in a
proprietary program, the partner will have the right of first refusal to develop
the compound or terminate its further development or to allow the Company to
commercialize the compound independently or with a third party in exchange for
royalty payments from the Company on product sales.
 
     In addition to the medicinal chemistry compounds, the Company also makes
extensive use of natural product compounds in fungal fermentation extracts.
Fungi are a known source of novel pharmaceuticals, including penicillin,
cephalosporin, lovastatin, prevastatin and cyclosporin A. The Company has
established a collaboration with a company specializing in fungal fermentation
products in which the Company sponsors the research and development of fungal
extracts. Pursuant to this collaboration, the Company has acquired more than
60,000 extracts of fungal samples for its proprietary uses and has the capacity
to add to this collection at the rate of 1,000 to 2,000 samples per week.
 
     Regardless of whether a lead compound is obtained by traditional or live
cell-based assays, the pharmaceutical properties of that compound must be
optimized before clinical development begins. Traditional lead optimization
requires medicinal chemists to synthesize new analogs. This methodology is
limited to producing approximately five to 20 new analogs per week.
Combinatorial chemistry techniques, however, enable the rapid production of
hundreds of chemical analogs per week. In a recent pilot program conducted by
the Company, nearly 3,000 analogs of a lead compound in one of the Company's
proprietary programs were synthesized over three months. The Company is
automating its combinatorial chemistry synthesis program in order to produce
analogs of lead compounds more rapidly. The Company believes that the continued
development of this technology will not only provide for a rapid expansion in
its proprietary libraries of medicinal compounds, but also accelerate the
Company's ability to rapidly analog lead compounds from its screening programs.
 
ONCOGENE SCIENCE'S STRATEGY
 
     The Company's goal is to discover and develop novel small molecule drugs
through proprietary and collaborative drug discovery programs using its
proprietary technology platform.
 
     The Company's strategy includes the following key elements:
 
     - Enhance Capabilities in Drug Discovery.  The Company is seeking to
       enhance its drug discovery operations by combining new capabilities in
       combinatorial chemistry with its industry leading robotics and
       information technologies to optimize leads more quickly and effectively.
       The Company is also developing new live-cell assays to detect complex
       intra-cellular mechanisms thereby enhancing the potential of discovering
       lead compounds.
 
     - Maintain and Expand Collaboration with Pharmaceutical Partners.  The
       Company will seek to maintain and expand collaborations with
       pharmaceutical companies to provide funding, development and
       commercialization capabilities, which enables the Company to focus on its
       core strengths in drug discovery. The Company has collaborations with
       four major pharmaceutical companies with which it is pursuing over 20
       protein targets for various diseases.
 
     - Expand Capabilities to Advance Internal Proprietary Programs.  The
       Company will seek to expand its proprietary drug discovery efforts to
       develop lead compounds through early clinical trials. The Company
       believes that by seeking collaborative partners later in the development
       process, it will be able to realize more favorable terms for the funding,
       development and commercialization of potential drug candidates.

  (1) For most of the Company's programs in the "Discovery" phase, the target
      proteins are either undergoing high throughput screening or lead
      compounds identified in these screens are being evaluated. Multiple lead
      compounds may exist for any target protein. These lead compounds may be
      at different stages of development, as indicated in the table above.
 
  (2) In the "Preclinical" phase, the Company or its collaborative partners
      optimize lead compounds and conduct laboratory pharmacology and
      toxicology testing.
 
  (3) "Phase I" clinical trials consist of small scale safety trials typically
      in healthy human volunteers. The Company expects to conduct Phase I
      clinical trials of TGF-SS3 for oral mucositis in 1996. No assurance can
      be given that Phase I clinical trials will begin when planned, if at
      all.
 
  (4) "Phase II" clinical trials entail testing of compounds in humans for
      safety and efficacy in a limited patient population. The Company expects
      Ciba will commence Phase II efficacy studies with respect to the TGF-SS3
      for wound healing indications in 1996. No assurance can be given that
      Phase II clinical trials will begin when planned, if at all.
 
  SMALL MOLECULE COLLABORATIVE PROGRAMS
 
     As part of its business strategy, Oncogene Science pursues collaborations
with pharmaceutical companies to combine the Company's drug discovery
capabilities with the collaborators' development and financial resources.
Typically, the Company's collaborations provide for its partners to make
milestone or other payments in support of the Company's research programs and to
pay royalties on sales of any resulting products. The collaborative partners
retain manufacturing and marketing rights worldwide. In all cases, the

Company's collaborative partners give the Company access to their compound
libraries for screening against the target genes under their respective
collaborations. Certain pharmaceutical collaborators make their compound
libraries available to the Company for additional research outside the
collaborative programs. Generally, each collaborative research agreement
prohibits the Company from pursuing drug discovery research relating to the
target proteins identified under the collaboration with any third party. The
Company is currently in discussions with several pharmaceutical companies
regarding potential collaborations or other ventures related to the discovery or
optimization of lead compounds or the clinical development and commercialization
of potential product candidates. There can be no assurance, however, that
current collaborations will be successful, any new collaboration will be
established, or if established, will be on terms favorable to the Company.
Failure to either maintain its existing, or enter into any new, collaborations
could limit the scope of the Company's drug discovery and development
activities, particularly if alternative sources of funding are unavailable. Such
failure could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     The Company's existing collaborations are as follows:
 
     Pfizer Inc.
 
     In April 1986, Pfizer and the Company entered into a collaborative research
agreement and several other related agreements. During the first five years of
the collaboration, the Company and Pfizer focused principally on understanding
the molecular biology of oncogenes. In 1991, Pfizer and the Company renewed the
collaboration for a new five-year term and expanded the resources and scope of
the collaboration to focus on the discovery and development of cancer
therapeutic products that target oncogenes and anti-oncogenes. Oncogenes play a
key role in the conversion of normal cells to a cancerous state. Anti-oncogenes,
or tumor suppressor genes, encode proteins that generally function to block the
proliferative growth of particular cell types. A loss of function of certain
tumor suppressor genes can result in uncontrolled cell growth.
 
     Currently, the Company's collaboration with Pfizer focuses on discovering
compounds that act upon eight target proteins involved in cancer. The Company's
screening program has resulted in the identification of a proprietary lead
compound that inhibits a protein associated with a number of major cancers.
Pfizer is currently conducting pre-IND safety and toxicity studies on this
compound. If such studies are successful, the Company expects that Pfizer may
file an IND as early as the second half of 1996. The success of such studies and
the continued development of this compound depends on several factors outside
the control of the Company, including the amount and timing of resources devoted
by Pfizer and the successful optimization of the compound. There can be no
assurance that this schedule will be met or that an IND for this lead compound
will be filed.
 
     All patent rights and patentable inventions derived from the research under
this collaboration are owned jointly by the Company and Pfizer. The Company is
obligated to file, prosecute and maintain such patents. The Company has granted
Pfizer an exclusive, worldwide license to make, use, and sell the therapeutic
products resulting from this collaboration in exchange for royalty payments.
This license terminates on the date of the last to expire of the Company's
relevant patent rights.
 
     Pfizer will be responsible for the clinical development, regulatory
approval, manufacturing and marketing of any products derived from the
collaborative research program. However, the collaborative research agreement
does not obligate Pfizer to pursue these activities. Generally, the Company is
prohibited during the term of the contract from pursuing or sponsoring research
aimed at discovery of drugs for the treatment of cancer. If the Company becomes
aware of an opportunity to pursue such research, it must notify Pfizer of this
opportunity and negotiate in good faith for a period of 120 days. If the parties
fail to reach agreement to include this opportunity in their collaboration, the
Company may pursue the opportunity independently. Pfizer is subject to a similar
restriction to the extent it desires to pursue any opportunity with a third
party, but Pfizer is not prohibited from pursuing any cancer research on its
own. The collaborative research agreement may be terminated early by either
party upon the occurrence of certain defaults by the other party. Any
termination of the collaboration resulting from a Pfizer default will cause a
termination of Pfizer's license rights. Pfizer will retain its license rights if
it terminates the agreement in response to a default by the Company.

     From 1986 to 1991, Pfizer paid an aggregate amount of $13.7 million to the
Company in research funding. In addition, during the current five-year term of
the collaboration the Company received or accrued an aggregate of $18.1 million
through December 31, 1995 in research payments from Pfizer. In 1986, Pfizer
purchased 587,500 shares of the Company's common stock, which constitutes
approximately 3.4% of the Company's outstanding common stock, for an aggregate
purchase price of $3,525,000. The current collaborative research agreement
expires on March 31, 1996. The Company expects this agreement to be renewed
under substantially the same terms, effective April 1, 1996. There can be no
assurance, however, that the collaborative research agreement with Pfizer will
be renewed on similar terms, or at all. The failure to renew this collaboration
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
     Hoechst Marion Roussel, Inc.
 
     The Company is pursuing various areas jointly with HMRI. In July 1995, the
pharmaceutical operations of MMDI, Hoechst and Hoechst Roussel combined into one
entity, HMRI. Prior to this date, the Company had collaborative agreements with
all three of these companies. The Company and HMRI have agreed in principle to
consolidate these agreements into one collaborative program and are negotiating
the terms of this ongoing collaboration. The Company believes that this
consolidation will result in a stronger, more flexible collaborative program,
although it expects the total level of funding from HMRI will be less than the
aggregate funding from the three previously separate entities. In anticipation
of the HMRI transaction, during fiscal 1995 the Company reallocated resources
and reduced expenses under these collaborative programs. HMRI is responsible for
funding the costs of the Company's development of the assay cell lines and
compound screening, and as of December 31, 1995, the Company had received or
accrued an aggregate of $9.3 million in research funding from HMRI and its
predecessors, of which $6.2 million of this amount was provided by MMDI. There
can be no assurance, however, that the Company and HMRI will successfully
negotiate a new agreement on terms favorable to the Company or at all. Failure
to secure such agreement could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     The Company's current collaborations with HMRI are as follows:
 
     Atherosclerosis. In December 1992, the Company entered into a five-year
collaborative research agreement with MMDI to discover and develop gene
transcription-based drugs to treat certain indications in cardiovascular
disease, focused principally on atherosclerosis. The Company completed screening
MMDI's compound library in its assays incorporating artherosclerosis targets,
which resulted in the identification of several lead compounds. HMRI later
requested that the Company screen the compound libraries formerly of Hoechst and
Hoechst Roussel against the same atherosclerosis targets to determine whether
additional lead compounds could be identified. The Company has completed this
additional screening and identified several more lead compounds.
 
     Inflammation, Arthritis and Metabolic Diseases. The Company entered into a
six-year collaborative research agreement with Hoechst, effective January 1993.
This collaboration is focused on discovering drugs for the treatment of
inflammation, arthritis and metabolic diseases. The Company has completed the
screening of HMRI's compound libraries against all three targets in this
collaboration. The lead compounds identified in these screens are undergoing
further analysis, including evaluation in animal models by HMRI.
 
     Alzheimer's. In October 1993, the Company entered into a six-year
collaborative research agreement with Hoechst Roussel pursuant to which it is
pursuing the discovery and development of gene transcription-based drugs to
treat Alzheimer's disease. The Company has completed screening HMRI's compound
libraries in cell-based assays and has identified a potential lead compound that
is undergoing further analysis.
 
     General. Under each of the Company's collaborative agreements with HMRI,
research committees were formed with equal representation from Oncogene Science
and HMRI. These committees, which meet at least three times a year, evaluate the
progress of the respective research programs, make priority and program
decisions, and prepare annual research plans identifying the drug targets to be
pursued and setting forth related research and budgeting information. The
Company is responsible for achieving its objectives in the annual research
plans. HMRI is responsible for assisting the Company in the pursuit of such
objectives,
 
                                        8
   9
 
including advancing the pharmacological assessment of compounds identified by
the Company, determining the chemical structure of the selected compounds,
identifying and selecting development candidates, pursuing clinical development
and regulatory approval, and developing manufacturing methods and pharmaceutical
formulations for the selected candidates. HMRI, in its sole discretion, may
elect not to undertake one or more of these steps.
 
     Generally, the Company is prohibited during the terms of the respective
contracts from pursuing or sponsoring research independent of HMRI on the
identified target proteins in the three areas of collaboration with HMRI. HMRI
is prohibited from sponsoring research with third parties employing the
Company's gene transcription technology on the identified target proteins. The
collaborative research agreements may be terminated early by either party upon
the occurrence of certain defaults by the other party. Any termination by the
Company resulting from an HMRI default will cause a termination of certain of
HMRI's license rights. HMRI will retain its license rights if it terminates an
agreement in response to a default by the Company.
 
     The Company granted to MMDI an exclusive, worldwide license with respect
to, among other things, the use, manufacture and sale of products resulting from
their research collaboration. HMRI has the right to obtain an exclusive,
worldwide license from the Company with respect to any therapeutic product
derived from the original Hoechst and Hoechst Roussel research programs. In
exchange for these licenses, HMRI will pay royalties to the Company on sales of
such products. The license will become non-exclusive, and HMRI's obligation to
pay royalties on sales will terminate in each country, in the case of a patented
product, when the patent expires in such country, and in the case of a
non-patented product, ten years after the first commercial sale of such product
in such country. The Company and HMRI have mutually exclusive rights and
obligations to prosecute and maintain patent rights related to various specified
areas of the research under the original MMDI collaboration.
 
     Wyeth-Ayerst Laboratories
 
     In December 1991, the Company entered into a two-year collaborative
research agreement with Wyeth, which was extended for an additional three-year
term in December 1993. The purpose of the agreement is to discover and develop
transcription-based drugs for the treatment of diabetes, immune system
modulation, asthma and osteoporosis. This collaboration has been successful in
identifying active compounds on all four protein targets. Wyeth is continuing
preclinical evaluation of these compounds, and lead compounds identified for a
diabetes target have been shown to be active in animal studies, although there
can be no assurance that a safe and effective compound will be identified for
clinical evaluation.
 
     Under the agreement, a research committee, composed of representatives from
the Company and Wyeth, prepares an annual research plan describing the goals of
the collaboration for the current year. The Company is responsible for achieving
the objectives set forth in the annual research plan. Wyeth is required to make
reasonably diligent efforts to advance the pharmacological assessment of
compounds identified by the Company, determine the chemical structure of the
compounds and make related compounds to determine the relationship between
structure and activity. Wyeth is also responsible for selecting development
candidates, assessing the safety of the development candidates in animals and
human patients under conditions designed to meet FDA requirements, and
developing manufacturing methods and pharmaceutical formulations for those
selected candidates.
 
     The Company has granted to Wyeth an option to obtain exclusive, worldwide
licenses with respect to products resulting from this collaboration in exchange
for royalties to the Company on sales of such products. Under the agreement, all
technology and patent rights will remain owned by the respective parties and
each party has the right to prosecute and maintain its own patents.
 
     During the term of this agreement, Oncogene Science is prohibited from
conducting or sponsoring research related to any target of its collaboration
with Wyeth outside of this collaboration. Wyeth is not prohibited from
conducting or sponsoring such research. The collaborative research agreement may
be terminated early by either party upon the occurrence of certain defaults by
the other party. Any termination by the Company resulting from a Wyeth default
will cause a termination of Wyeth's license rights. Wyeth will retain its
license rights if it terminates the agreement in response to a default by the
Company. Currently on
 
                                        9
   10
 
four months notice, Wyeth may terminate the agreement without cause and retain
its license rights. Wyeth has funded the Company's drug discovery efforts under
this collaboration. As of December 31, 1995, Wyeth had provided the Company with
an aggregate of $4.9 million in research funding. The agreement will expire on
December 31, 1996. The parties have not yet determined whether to renew this
agreement, and there can be no assurance that this agreement will be renewed on
terms favorable to the Company, if at all.
 
  RECOMBINANT TGF-[BETA]3 COLLABORATION
 
     In addition to its small molecule discovery programs, the Company has
developed the recombinant protein TGF-[BETA]3 for various indications. The
Company believes it was the first to isolate TGF-[BETA]3, a naturally occurring
human growth factor that exerts either stimulatory or inhibitory effects
depending upon the particular cell type to which it is applied. Topical or local
application of TGF-[BETA]3 in animal studies has been shown to enhance and
accelerate wound healing. Similarly, animal studies have shown that TGF-[BETA]3
can minimize the severity of ulcerative mucositis when administered prior to
chemotherapy.
 
     The Company entered into an agreement with Ciba in April 1995 expanding the
scope of the two companies' prior collaborative efforts with respect to
TGF-[BETA]3. This agreement grants to Ciba an exclusive, worldwide license to
use and sell TGF-[BETA]3 products for oral mucositis and wound healing, as well
as certain other indications, including psoriasis, and an option to obtain
rights to all indications of TGF-[BETA]3 currently held by the Company. In
addition, Ciba has the worldwide license to manufacture TGF-[BETA]3 for all
indications.
 
     Oral Mucositis. Oral mucositis is a painful, often debilitating condition
characterized by mouth lesions that frequently occur as a side effect of
chemotherapy. In the U.S., over one million new cases of cancer occur each year,
over half of which receive multiple treatments of chemotherapy. Approximately
20% to 40% of chemotherapy patients exhibit some degree of oral mucositis. Most
chemotherapeutic agents exert their lethal effects primarily against cancerous
cells undergoing active growth. Chemotherapeutic agents also attack normal cells
that are subject to rapid division, such as the epithelial cells lining the
mouth. The Company and Ciba have developed topical formulations of TGF-[BETA]3
to temporarily inhibit the high proliferative growth rate of certain normal
cells in the mouth. The Company's objective is to develop TGF-[BETA]3 to reduce
the toxicity associated with chemotherapeutic agents.
 
     Under its agreement with Ciba, the Company will fund Phase I clinical
trials of TGF-[BETA]3 for oral mucositis in the U.S. and Ciba will fund Phase I
clinical trials in Europe, and if successful, Ciba will fund all Phase II and
III clinical trials. An IND for this indication was filed by Ciba in January
1996. The Company expects to commence Phase I clinical trials in the U.S. in
1996. A second Phase I study is also expected to be conducted by Ciba in Europe
in 1996 to demonstrate safety and determine the maximum tolerated dose. If these
studies are successful, the Company expects that Ciba will initiate two Phase II
studies in 1997. No assurance can be given that any of these clinical trials
will demonstrate safety and efficacy or will begin when planned, or at all, in
part for the reasons discussed below.
 
     Wound Healing. In addition to its program for the development of
TGF-[BETA]3 to treat oral mucositis, the Company is collaborating with Ciba in
the development of TGF-[BETA]3 in an application to promote soft tissue wound
healing, including venous leg ulcers, decubitus ulcers (pressure sores) and
diabetic foot ulcers. Such chronic cutaneous ulcers afflict an estimated three
million people in the U.S. TGF-[BETA]3 is believed to promote wound healing by
recruiting inflammatory cells, such as neutrophils and macrophages, and
fibroblasts, and stimulating fibroblast proliferation and extracellular matrix
production. TGF-[BETA]3 is also believed to stimulate angiogenesis (new blood
vessel growth) at the wound site.
 
     To date, Ciba has completed two Phase I safety studies, one in Europe using
a single dose of TGF-[BETA]3 applied to intact skin, the other in the U.S. using
a multiple dose of TGF-[BETA]3 applied to intact skin. In both studies, the drug
was found to be well tolerated with no adverse effects. Ciba recently completed
Phase II-A safety/dose-finding studies in Europe, involving a single dose
administration to venous leg ulcer patients. The drug was found to be well
tolerated in these patients. There is an ongoing Phase II-A safety/dose-ranging
study in Europe involving a single dose administration to decubitus ulcer
patients. Ciba intends to initiate a clinical trial of venous leg ulcer patients
in Europe, and another clinical trial in pressure sore patients in the U.S. and
Canada, which are scheduled to commence in late 1996. In addition, Ciba intends
to conduct an additional Phase II venous leg ulcer, decubitus ulcer and burn
wound clinical trials in Japan in late 1996.
 
                                       10
   11
 
There can be no assurance that additional trials will demonstrate safety and
efficacy or will begin when planned, or at all in part for the reasons discussed
below.
 
     General. In exchange for its exclusive license with respect to the wound
healing, oral mucositis and certain other indications for TGF-[BETA]3, Ciba will
make royalty payments to the Company on the sale of TGF-[BETA]3 products. Also,
Ciba purchased 909,091 shares of the Company's Common Stock at $5.50 per share
for an aggregate purchase price of $5 million in April 1995. If, and at the
time, Ciba decides to initiate Phase III clinical trials (or the equivalent in
Europe) for oral mucositis, Ciba will be required to make a $10 million payment
to the Company. In exchange for such payment, Ciba's license will be expanded to
cover all other indications for TGF-[BETA]3. Ciba has the option to make such
payment by purchasing $10 million of the Company's Common Stock at the higher of
$5.50 per share or the then current market price. In the absence of a decision
by Ciba to pursue such clinical trials, Ciba may nonetheless exercise an option
within four years from inception of the agreement, or by April 1999, to expand
its license under the agreement to cover all indications for TGF-[BETA]3 by
making the $10 million payment.
 
     Ciba has the right to discontinue clinical development at any time, in
which case all of its license rights from the Company with respect to
TGF-[BETA]3 will be terminated and it will make available to the Company the
results of all clinical work up to the date such activity was discontinued.
Under the agreement, Ciba has the right to manufacture TGF-[BETA]3, and will
supply the Company and any licensee of the Company with all developmental and
commercial quantities of TGF-[BETA]3 required. With respect to the Company's
commercial requirements in the future, if any, Ciba and the Company have agreed
to negotiate terms pursuant to which Ciba will supply TGF-[BETA]3, subject to a
specified pricing formula should the parties fail to reach agreement. Ciba
recently experienced delays in manufacturing TGF-[BETA]3 due to the failure of
its contract manufacturer's facilities to comply with GMP regulations. If Ciba
is unable or unwilling to scale up its capacity to supply TGF-[BETA]3 to the
Company or its licensees in sufficient quantities, Ciba will license to the
Company its technology relating to the production of TGF-[BETA]3 on terms to be
negotiated within specified parameters. There can be no assurance that the
TGF-[BETA]3 program will not experience significant delays as a result of Ciba's
failure to supply TGF-[BETA]3 on a timely basis.
 
     The Company's agreement with Ciba ends upon the expiration of the last
Company's patents relating to TGF-[BETA]3.
 
  PROPRIETARY DRUG DISCOVERY AND DEVELOPMENT
 
     In addition to its collaborative programs, the Company has undertaken
independent efforts to discover and develop gene transcription-based
therapeutics in various areas. The Company initiated its proprietary programs in
1994 and is currently screening compounds against multiple target proteins in
live-cell assays associated with chronic anemias, virology and muscle wasting
disorders. The goal of these programs is to identify small molecule,
orally-active compounds that will regulate the expression of key proteins
associated with these diseases. Generally, the Company's objective with respect
to its proprietary programs is to identify lead compounds, transition them
through preclinical development and manage clinical development through
early-stage clinical trials. If its drug discovery efforts are successful, the
Company intends to partner with a large pharmaceutical firm for clinical and
commercial development of each potential proprietary product. There can be no
assurance that lead compounds identified in the Company's proprietary programs
will progress into clinical development, that any such compounds will proceed
successfully through clinical trials or that the Company will secure any
collaboration agreements with respect to any program or compound.
 
     Chronic Anemias
 
     Erythropoietin. Currently, the Company's proprietary discovery and
development efforts are focused principally on the protein erythropoietin
("EPO"). Injectable recombinant EPO is widely used for the treatment of anemia
due to chronic renal failure and anemia associated with chemotherapy for AIDS
and cancer. Sales of EPO therapeutics generated worldwide revenues of over $2.0
billion in 1995. EPO is also being tested for use in anemia resulting from other
indications. The Company believes the requirement that it be administered by
injection may place limitations on its more widespread use. The Company believes
that a
 
                                       11
   12
 
significant market opportunity exists for an effective, oral, small molecular
weight compound that could induce the cellular production of EPO. The Company's
gene transcription screens have resulted in the identification of several potent
lead compounds that increase the expression of EPO in cell lines which naturally
secrete EPO. The Company is undertaking early preclinical development, which
involves medicinal chemistry and pharmacology, of these lead compounds.
 
     Fetal Hemoglobin.  Sickle cell anemia and [BETA]-thalassemia are caused by
genetic mutations which result in the mutation, absence or decrease in the
[BETA] chain of hemoglobin (the protein in red blood cells that binds oxygen).
Currently available treatments for both of these diseases are inadequate and
expensive. In sickle cell anemia, "sickled" cells become trapped in the spleen
and break down to produce symptoms of anemia. The cost of treating each sickle
cell patient in the U.S. has been estimated to be in excess of $60,000 annually.
Regular blood transfusions are the mainstay of current therapy for
[BETA]-thalassemia. The Company's approach to address sickle cell anemia and
[BETA]-thalassemia is to discover a small molecule compound that increases
expression of a fetal hemoglobin ("HbF") gene to compensate for the defects in
the adult [BETA] chain of hemoglobin. The Company has developed an assay to
determine the ability of test compounds to induce the production of HbF. The
Company's goal is to establish, through additional screening and evaluation, a
lead compound that induces expression of HbF as a candidate for clinical
development in this area.
 
     Virology
 
     The Company's virology program targets certain proteins which are believed
to be essential to viral pathogenesis. The current viral targets in this program
include human immunodeficiency virus, herpes simplex virus, human hepatitis B
virus ("HBV"), human hepatitis C virus ("HCV"), and influenza virus. For each of
these diseases there is an unmet need for new effective, anti-viral drugs. For
example, since the start of the AIDS epidemic, over 500,000 cases have been
reported in the U.S. Furthermore, HBV is a chronic infection that can progress
to cirrhosis and liver cancer, making HBV one of the most significant of all
infectious diseases. HCV is also a major viral pathogen. In the U.S., over 3.5
million people are infected with HCV, and the virus may account for 40% of all
chronic liver disease. Currently, the principal therapy for HCV is alpha
interferon administered by injection, but this therapy has limited efficacy.
 
     The Company's principal drug discovery approach in its virology program
focuses on discovering small molecule compounds that affect transcription of
novel gene sequences in the virus. The Company has designed four novel assays
that target these genes. The Company is in discussions with a pharmaceutical
company regarding a potential virology collaboration, although there can be no
assurance that a collaboration will be established.
 
     Muscle Wasting Disorders
 
     Cachexia.  Cachexia is the accelerated breakdown of skeletal muscle coupled
with a high degree of morbidity and organ dysfunction. Cachexia is characterized
by progressive weight loss and a depletion of muscle. This "wasting syndrome" is
associated with a wide variety of chronic disease states and is particularly
common in both advanced metastic cancer and AIDS. While the exact mechanisms
responsible for the development of cachexia are not completely elucidated, the
Company believes both stimulators, or agonists, of growth hormone and
inhibitors, or antagonists, of tumor necrosis factor alpha could prove to be
effective agents in the treatment of this condition.
 
     Human growth hormone (hGH) is a potent anabolic agent known to stimulate
protein accretion and to increase muscle mass. The usefulness of this hormone as
a therapy for wasting disorders associated with cancer, AIDS and old age is
being actively investigated by several companies. Furthermore hGH has completed
Phase III clinical trials and is pending FDA review. Recombinant hGH protein
requires injection for administration, and the current costs of this drug range
from $10,000 to $30,000 per patient annually. Recombinant hGH generated revenues
of over $1 billion in the treatment of growth disorders in 1994. The Company
believes there is a major market opportunity for an orally active,
cost-effective drug which acts to induce hGH gene expression and increase levels
of hGH in the body.
 
                                       12
   13
 
     Muscular Dystrophy.  Duchenne's and Becker's muscular dystrophy are due to
defects of the dystrophin gene. The Company is developing multiple approaches in
its discovery efforts with respect to a drug for the treatment of muscular
dystrophy. A portion of the funding for this project has been provided by the
Association Francaise Contre Les Myopathies.
 
CANCER DIAGNOSTICS
 
     The Company is engaged in the development of a series of cancer diagnostic
tests based on oncogenes, tumor suppressor genes and other gene targets whose
proteins are directly involved in tumor growth or metastasis. One line of these
tests utilizes immunoassays and monoclonal antibodies to detect these cancer
markers in urine and serum. The other line of diagnostic tests utilizes a series
of monoclonal antibodies capable of measuring the cancer markers in tissue
sections using immunohistochemistry techniques such as manual pathology
diagnostic tests and image analysis. Both of these lines of tests are designed
to aid oncologists in the confirmation, monitoring, staging, screening or
prognosis of human cancer. These tests may enable reference labs and physicians
to select more effective types of treatment, more easily monitor patients during
therapy, or diagnose cancer at an earlier stage. The current focus of the
Company's diagnostic development program is on breast and colon cancer, but the
Company believes that many of the cancer markers in its program may have
clinical utility for other human tumors, such as lung, prostate, ovarian and
stomach cancer. None of these diagnostic tests have completed clinical
development or received FDA clearance to be marketed in the U.S.
 
     The Company has been pursuing serum and tissue based cancer diagnostic
products in collaboration with Becton under a collaborative program started in
October 1991 (after an earlier collaboration from 1984 to 1989). During 1995,
the Company and Becton agreed that Becton would narrow its focus in the program
exclusively to tissue-based diagnostic tests including immunohistochemistry and
that the Company would continue its development program in serum-based cancer
diagnostics. Becton has reduced funding under this program in fiscal 1996 and
the Company is uncertain as to Becton's ongoing support of this program
thereafter. The Company believes Becton will seek FDA approval for one or more
immunohistochemistry tests for the manual pathology market in the next 12 to 18
months, although there is no assurance that such an approval will be received on
a timely basis, if at all. The Company is actively seeking to form
collaborations with one or more partners for the clinical and commercial
development of its serum-based diagnostic products. No assurance can be given
that the Company will establish such a collaboration on acceptable terms or at
all.
 
INTELLECTUAL PROPERTY
 
     The Company believes that patents and other proprietary rights are vital to
its business. The Company's policy is to protect its intellectual property
rights in technology developed by its scientific staff by a variety of means,
including applying for patents in the United States and other major
industrialized countries. The Company also relies upon trade secrets and
improvements, unpatented proprietary know-how and continuing technological
innovations to develop and maintain its competitive position. In this regard,
the Company seeks restrictions in its agreements with third parties, including
research institutions, with respect to the use and disclosure of the Company's
proprietary technology. The Company also has confidentiality agreements with its
employees, consultants and scientific advisors.
 
     The Company currently owns 12 U.S. patents and 35 foreign patents. In
addition, the Company currently has pending 30 applications for United States
patents, 3 of which have been allowed, and 33 applications for foreign patents,
2 of which have been allowed. In addition, other institutions have granted
exclusive rights under their United States and foreign patents and patent
applications to the Company.
 
     There can be no assurance that patents will issue based upon the Company's
pending patent applications or any applications which it may file in the future,
that any patent issued will adequately protect a commercially marketable product
or process or that any patent issued will not be circumvented or infringed by
others or declared invalid or unenforceable. Moreover, there can be no assurance
that others may not independently develop the same or similar technology or
obtain access to the Company's proprietary technology. The Company is aware of
patents issued to other entities with respect to technology potentially
 
                                       13
   14
 
useful to the Company and, in some cases, related to products and processes
being used or developed by the Company. The Company currently cannot assess the
effect, if any, that these patents may have on its operations in the future. The
extent to which efforts by other researchers resulted or will result in patents
and the extent to which the issuance of patents to other entities would have a
material adverse effect on the Company or would force the Company to seek
licenses from such other entities currently is unknown as is the availability to
the Company of licenses from such other entities, and whether, if available,
such licenses can be obtained on terms acceptable to the Company.
 
     In the cancer diagnostics area, the Company has a U.S. patent relating to
an assay which the Company is seeking to develop for the detection of protein
encoded by the neu oncogene ("neu") in serum. The Company is aware that a patent
application relating to a similar assay was filed by a third party shortly after
the Company filed the application from which its U.S. patent issued. It is
possible that the Company may have to participate in an interference proceeding
with such third party to determine priority of invention, which could result in
substantial cost to the Company. The Company cannot predict whether such an
interference proceeding will occur, or if it does occur, whether the Company
will prevail. If the Company does not prevail, it may not be able to
commercialize its assay for neu in serum without a license from such third
party, which may not be available on acceptable terms or at all.
 
     The Company is aware of several U.S. and foreign patents owned by others
who may allege infringement by products, including TGF-[BETA]3, which the
Company is seeking to develop in collaboration with a partner. Genentech has
U.S. patents relating to certain recombinant materials and procedures for
producing members of the TGF-[BETA] family, including TGF-[BETA]3. In addition,
the Company believes that Genentech has license rights under a United States
Government patent relating to work done at the National Institute of Health of
the U.S. Department of Health and Human Services involving the identification
and isolation of TGF-[BETA]1.
 
     The Company believes that the currently planned development by the Company
and Ciba, its collaborative partner for TGF-[BETA]3, involving manufacture in
Europe by Ciba of TGF-[BETA]3 in nonmammalian cells for subsequent distribution
in Europe and the United States does not infringe any valid claim of any patent
owned by Genentech or by the U.S. Government. The Company and Ciba have taken
and continue to take such actions, including the pursuit of opposition
proceedings against foreign patents, as they deem prudent to minimize the
possibility of any charge of patent infringement being validly raised against
Ciba or the Company based on such patents.
 
     The Company does not believe that it is infringing any valid claim of any
patents owned by third parties. However, there can be no assurance that a
contrary position will not be asserted, or that, if asserted, such a position
would not prevail. If a patent infringement lawsuit were brought against the
Company or its licensees, the Company could incur substantial costs in defense
of such a suit, which could have a material adverse effect on the Company's
business, financial condition and results of operation, regardless of whether
the Company were successful in the defense. Furthermore, the Company's royalties
may be reduced by up to 50% if its licensees or collaborative partners are
required to obtain licenses from third parties whose patent rights are infringed
by the Company's products, technology or operations.
 
COMPETITION
 
     The pharmaceutical, biotechnology and diagnostics industries are intensely
competitive. The Company faces, and will continue to face, intense competition
from organizations such as large pharmaceutical companies, diagnostic companies,
biotechnology companies, academic and research institutions and government
agencies. The Company is subject to significant competition from industry
participants who are pursuing the same or similar technologies as those which
constitute the Company's technology platform and from organizations that are
pursuing pharmaceutical products or therapies or diagnostic products that are
competitive with the Company's potential products. Most of the organizations
competing with the Company have greater capital resources, research and
development staffs and facilities, and greater experience in drug discovery and
development, obtaining regulatory approval and pharmaceutical product
manufacturing and marketing. The Company's major competitors include fully
integrated pharmaceutical companies, such as Merck & Co., Inc., Glaxo Wellcome
Inc. and SmithKline Beecham plc, that conduct extensive drug discovery efforts
and are developing novel small molecule pharmaceuticals, as well as numerous
smaller companies.
 
                                       14
   15
 
     The Company's technology platform consists principally of utilizing
genetically engineered live cells, gene transcription technologies and high
throughput drug screening. Pharmaceutical and biotechnology companies and others
are active in all of these areas. Ligand Pharmaceuticals Inc., a publicly owned
company, employs live-cell assays, gene transcription, and high throughput
robotics in its drug discovery operations. Numerous other companies use one or
more of these technologies. Several private companies, including Tularik Inc.,
Signal Pharmaceuticals Inc. and Scriptgen Pharmaceuticals, Inc., pursue drug
discovery using gene transcription methods. Other organizations may acquire or
develop technology superior to that of the Company.
 
     Companies pursuing different but related fields also present significant
competition for the Company. For example, research efforts with respect to gene
sequencing and mapping are identifying new and potentially superior target
genes. In addition, alternative drug discovery strategies, such as rational drug
design, may prove more effective than those pursued by the Company. Furthermore,
competing entities may have access to more diverse compounds for testing by
virtue of larger compound libraries or through combinatorial chemistry skills or
other means. These include Pharmacopeia, Inc., a publicly traded company,
CombiChem, Inc. and ArQule, Inc., all of which have major collaborations with
leading pharmaceutical companies. There can be no assurance that the Company's
competitors will not succeed in developing technologies or products that are
more effective than those of the Company or that would render the Company's
products or technologies obsolete or noncompetitive.
 
     With respect to the Company's small molecule drug discovery programs, other
companies have potential drugs in clinical trials to treat all the disease areas
for which the Company is seeking to discover and develop drug candidates. These
competing drug candidates are further advanced in clinical development than are
any of the Company's potential products in its small molecule programs and may
result in effective, commercially successful products. Even if the Company and
its collaborative partners are successful in developing effective drugs, there
can be no assurance that the Company's products will compete effectively with
such products. No assurance can be given that the Company's competitors will not
succeed in developing and marketing products that either are more effective than
those that may be developed by the Company and its collaborative partners or are
marketed prior to any products developed by the Company or its collaborative
partners.
 
     With respect to its efforts to develop TGF-[BETA]3 for various indications,
the Company is aware of competing growth factor proteins in clinical trials, and
competing treatment regimens, for wound healing indications. Platelet derived
growth factor (PDGF) for diabetic skin ulcers, under development by Chiron
Corporation and Johnson & Johnson, has completed Phase III clinical trials in
the U.S. Chiron Corporation and Johnson & Johnson have announced that they
intend to file a Product Licensing Application ("PLA") for PDGF with the FDA in
1996. Fibroblast growth factor (FGF) for chronic dermal ulcers, under
development by Scios Nova Inc. and Kaken Pharmaceutical Co., Ltd., is in Phase
III clinical trials in Japan. TGF-[BETA]2 for leg ulcers, under development by
Genzyme Corp. and Celtrix Pharmaceuticals, Inc., is in Phase II clinical trials
in the U.S. No assurance can be given that the Company and Ciba will
successfully develop TGF-[BETA]3 for any indication, including wound healing.
Furthermore, if any of the competing growth factor product candidates listed
above or other growth factors proves to be effective for wound healing
indications, there can be no assurance that any product developed by the Company
will be able to compete effectively with such product or products.
 
     Other competing approaches to the treatment of chronic wounds include
comprehensive service-based patient centers, which are dedicated to intensive
wound management. These centers may include the use of autologous growth factor
therapy, in which extracts prepared from the patient's own platelets are used to
treat the wounds. Surgical intervention is also frequently employed, which may
involve partial amputation and/or surgical revascularization. The use of skin
grafts to treat wounds, either autografts (skin from elsewhere on the same
patient) or cultured allografts, are also being investigated by several
companies, including Advanced Tissues Sciences, Inc. and Organogenesis, Inc. No
assurance can be given that TGF-[BETA]3 will prove to be safe and effective or
will compete successfully against current and emerging therapies for any
particular clinical indication.
 
     The Company believes that its ability to compete successfully will be based
on, among other things, its ability to create and maintain scientifically
advanced technology, attract and retain scientific personnel with a
 
                                       15
   16
 
broad range of expertise, obtain patent protection or otherwise develop
proprietary products or processes, enter into collaborative arrangements, and,
independently or with its collaborative partners, conduct clinical trials,
obtain required government approvals on a timely basis, and commercialize its
products.
 
MANUFACTURING
 
     Ciba has the exclusive right to, and the Company will rely on Ciba for, the
manufacture of TGF-[BETA]3 for all of the Company's requirements for clinical
trials and commercial purposes. Oncogene Science believes that, if Ciba should
fail to meet its requirements, there are other companies that could manufacture
and supply TGF-[BETA]3, although there can be no assurance that this could be
accomplished on a timely basis, or at all.
 
     The Company is, and will remain, dependent on its collaborative partners
and third parties for the manufacture of all products. There can be no assurance
that the Company will be able to manufacture products that will meet the
Company's demands for quality, quantity, cost and timeliness or otherwise
contract for manufacturing capabilities on acceptable terms. The failure of the
Company to successfully contract for the manufacture of products that satisfy
its requirements for quality, quantity, cost and timeliness would prevent the
Company from conducting preclinical testing and clinical trials and
commercializing its products.
 
MARKETING AND SALES
 
     The Company does not intend to develop its own marketing and sales
capabilities. Potential therapeutic products subject to the Company's
collaborative agreements with Pfizer, HMRI, Wyeth and Ciba, and potential
diagnostic products under the Company's collaboration with Becton, will be
marketed by those companies worldwide. The Company will receive royalties of up
to 10% on net sales of products, depending upon the nature of the product and
the ownership of the underlying technology. The Company expects that products
resulting from future collaborations in drug discovery and development and
diagnostic product development will be marketed under arrangements which are
similar to these agreements, although any collaborations established for
products resulting from proprietary programs may vary significantly.
 
GOVERNMENT REGULATION
 
     The Company and its collaborative partners are, and any potential products
discovered and developed thereto, will be subject to comprehensive regulation by
the FDA in the United States and by comparable authorities in other countries.
These national agencies and other federal, state, and local entities regulate,
among other things, the preclinical and clinical testing, safety, effectiveness,
approval, manufacture, labeling, marketing, export, storage, record keeping,
advertising, and promotion of pharmaceutical and diagnostic products.
 
     The process required by the FDA before pharmaceutical products may be
approved for marketing in the United States generally involves: (i) preclinical
laboratory and animal tests, (ii) submission to FDA of an investigational new
drug application, which must become effective before clinical trials may begin,
(iii) adequate and well controlled human clinical trials to establish the safety
and efficacy of the drug for its intended indication, (iv) submission to the FDA
of an NDA or, in the case of biological products, such as TGF-[BETA]3, a PLA,
and (v) FDA review of the NDA or PLA in order to determine, among other things,
whether the drug is safe and effective for its intended uses. There is no
assurance that FDA review process will result in product approval on a timely
basis, if at all.
 
     Preclinical tests include laboratory evaluation of product chemistry and
formulation, as well as animal studies, to assess the potential safety and
efficacy of the product. Certain preclinical tests are subject to FDA
regulations regarding current Good Laboratory Practices. The results of the
preclinical tests are submitted to the FDA as part of an IND and are reviewed by
the FDA prior to the commencement of clinical trials.
 
     Clinical trials are conducted under protocols that detail such matters as
the objectives of the study, the parameters to be used to monitor safety and the
efficacy criteria to be evaluated. Each protocol must be submitted to the FDA as
part of the IND.
 
                                       16
   17
 
     Clinical trials are typically conducted in three sequential phases, which
may overlap. During Phase I, when the drug is initially given to human subjects,
the product is tested for safety, dosage tolerance, absorption, metabolism,
distribution and excretion. Phase II involves studies in a limited patient
population to: (i) evaluate preliminarily the efficacy of the product for
specific, targeted indications, (ii) determine dosage tolerance and optimal
dosage, and (iii) identify possible adverse effects and safety risks. Phase III
trials are undertaken in order to further evaluate clinical efficacy and to
further test for safety within an expanded patient population. The FDA may
suspend or terminate clinical trials at any point in this process if it
concludes that clinical subjects are being exposed to an unacceptable health
risk.
 
     FDA approval of the Company's and its collaborators' products, including a
review of the manufacturing processes and facilities used to produce such
products, will be required before such products may be marketed in the United
States. The process of obtaining approvals from the FDA can be costly, time
consuming and subject to unanticipated delays. There can be no assurance that
approvals of the Company's proposed products, processes or facilities will be
granted on a timely basis, if at all. Any failure to obtain or delay in
obtaining such approvals would have a material adverse effect on the Company's
business, financial condition and results of operations. Moreover, even if
regulatory approval is granted, such approval may include significant
limitations on indicated uses for which a product could be marketed.
 
     Among the conditions for NDA approval is the requirement that the
prospective manufacturer's manufacturing procedures conform to GMP requirements,
which must be followed at all times. In complying with those requirements,
manufacturers (including a drug sponsor's third-party contract manufacturers)
must continue to expend time, money and effort in the area of production and
quality control to ensure compliance. Domestic manufacturing establishments are
subject to periodic inspections by the FDA in order to assess, among other
things, GMP compliance. To supply products for use in the United States, foreign
manufacturing establishments must comply with GMP and are subject to periodic
inspection by the FDA or by regulatory authorities in certain countries under
reciprocal agreements with the FDA.
 
     Both before and after approval is obtained, a product, its manufacturer and
the holder of the NDA for the product are subject to comprehensive regulatory
oversight. Violations of regulatory requirements at any stage, including the
preclinical and clinical testing process, the approval process, or thereafter
(including after approval) may result in various adverse consequences, including
the FDA's delay in approving or refusal to approve a product, withdrawal of an
approved product from the market, and the imposition of criminal penalties
against the manufacturer and NDA holder. In addition, later discovery of
previously unknown problems may result in restrictions on such product,
manufacturer or NDA holder, including withdrawal of the product from the market.
Also, new government requirements may be established that could delay or prevent
regulatory approval of the Company's products under development.
 
     For marketing outside the United States, the Company and its collaborators
and the drugs developed thereby, if any, will be subject to foreign regulatory
requirements governing human clinical trials and marketing approval for drugs
and diagnostic products. The requirements governing the conduct of clinical
trials, product licensing, pricing and reimbursement vary widely from country to
country. In addition, before a new drug may be exported from the U.S., it must
be the subject of an approved NDA or comply with FDA regulations pertaining to
INDs.
 
     In addition to regulations enforced by the FDA, the Company also is subject
to regulation under the Occupational Safety and Health Act, the Environmental
Protection Act, the Toxic Substances Control Act, the Resource Conservation and
Recovery Act and other present and future federal, state or local regulations.
The Company's research and development involves the controlled use of hazardous
materials, chemicals and various radioactive compounds. Although the Company
believes that its safety procedures for handling and disposing of such materials
comply with the standards prescribed by state and federal regulations, the risk
of accidental contamination or injury from these materials cannot be completely
eliminated. In the event of such an accident, the Company could be held liable
for any damages that result and any such liability could exceed the resources of
the Company.
 
     Diagnostic tests undergo different FDA review processes depending whether
they are classified as "biologicals" or "medical devices." For medical devices,
a 510(k) application (for a product substantially
 
                                       17
   18
 
equivalent to a product already on the market) or a premarket approval ("PMA")
application (generally, a new product or method that is not substantially
equivalent to an existing product) must be filed with, and approved by, the FDA
prior to commercialization. Obtaining premarket approval is a costly and time-
consuming process, comparable to that for new drugs. There can be no assurance
that the Company's cancer diagnostic product candidates will be submitted for
regulatory approval, or if submitted, that the Company would not be required to
seek pre-market approval as opposed to filing a 510(k) application.
 
EMPLOYEES
 
     The Company believes that its success will be largely dependent upon its
ability to attract and retain qualified personnel in scientific and technical
fields. As of December 31, 1995, the Company employed 107 persons, of whom 84
were primarily involved in research and development activities, with the
remainder engaged in executive and administrative capacities. Although the
Company believes that it has been successful to date in attracting skilled and
experienced scientific personnel, competition for such personnel is intense and
there can be no assurance that the Company will continue to be able to attract
and retain personnel of high scientific caliber. The Company considers its
employee relations to be good.
 
ITEM 2.  PROPERTIES
 
     The Company leases a 30,000 square foot facility located at 106 Charles
Lindbergh Boulevard, Uniondale, New York. This facility houses the Company's
principal executive offices and drug discovery laboratory. The Company also
leases an 11,000 square foot facility located at 80 Rogers Street/129 Binney
Street, Cambridge, Massachusetts. This facility contains the offices and
laboratories of the Company's diagnostic product operations. The Company
believes that its facilities will be adequate to meet current requirements for
the foreseeable future.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     There are no material legal proceedings pending against the Company.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     There were no matters submitted to a vote of security holders during the
fourth quarter of fiscal 1995.

     As of December 31, 1995, there were approximately 751 holders of record of
the Company's common stock. The Company has not paid any dividends since its
inception and does not intend to pay any dividends in the foreseeable future.
Declaration of dividends will depend, among other things, upon future earnings,
the operating and financial condition of the Company, its capital requirements
and general business conditions.

- ---------------
(a) During fiscal 1995, the Company sold its Research Products Business and also
     sold shares of its common stock to Ciba-Geigy, Ltd. (See Notes 3 and 8(c)
     to the Consolidated Financial Statements.)
 
(b) During fiscal 1994, the Company changed its method of accounting for
     marketable securities to adopt the provisions of the Statement of Financial
     Accounting Standards No.115, "Accounting for Certain Investments in Debt
     and Equity Securities".
 
(c) During fiscal 1993, the Company entered into collaborative agreements with
     Marion Merrell Dow and Hoechst AG and also sold shares of its common stock
     to Marion Merrell Dow (See Notes 4 and 8(c) of Notes to Consolidated
     Financial Statements.)
 
(d) During fiscal 1992, the Company acquired the cancer business of Applied
     bioTechnology and completed an offering of its common stock (see Notes 3
     and 8(d) of Notes to Consolidated Financial Statements).
 
ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS
 
REVENUES
 
     Total revenues of $15.9 million in fiscal 1995 decreased approximately
$434,000 or 3% compared to fiscal 1994 and total revenues of $16.3 million in
fiscal 1994 increased approximately $211,000 or 1% compared to fiscal 1993.
Collaborative program revenues increased by approximately $597,000 or 7% in
fiscal 1995 due to the commencement of an additional research program with HMRI
in April 1994, the expansion and extension of the collaborative research
agreement with Wyeth in March 1994 and increases in revenues under the Pfizer
agreement with respect to anti-cancer drugs. These increases were offset by
decreased funding from Pfizer associated with Pfizer's reduced participation in
the TGF-SS3 oral mucositis program in order to focus exclusively on its
collaborative programs with the Company related to the research and development
of small
 
                                       20
   21
 
molecule anti-cancer drugs. Previously, Pfizer had funded the Company's
TGF-[BETA]3 oral mucositis program in addition to its anti-cancer collaborative
program. Under a collaborative agreement with Ciba entered into in April 1995,
the Company will fund the development of TGF-[BETA]3 for oral mucositis through
the end of Phase I clinical trials and Ciba will fund its subsequent clinical
development. The increase in collaborative revenues in fiscal 1995 was offset by
decreases in sales of research products and other research revenues. The Company
sold its Research Products Business to Calbiochem-Novabiochem International,
Inc. in August 1995, and accordingly, there were no significant sales of
research products recorded after this date. Sales of research products decreased
approximately $651,000 or 13% in fiscal 1995 compared to fiscal 1994. Other
research revenues decreased approximately $380,000 or 17% in fiscal 1995
compared to fiscal 1994, which was largely the result of the expiration of a
U.S. government grant.
 
     The increase in total revenues in fiscal 1994 compared to fiscal 1993 is
attributable to increases of $1.6 million in collaborative research revenues
relating to the commencement of the additional HMRI collaborative program and a
milestone payment from MMDI, grant revenues and sales of research products,
offset by a $1.4 million decrease in revenues from Pfizer. Sales of research
products increased approximately $111,000 or 2% in fiscal 1994 compared to
fiscal 1993, due primarily to a change in the mix of products sold. Other
research revenues in fiscal 1994 increased by approximately $408,000 or 22%,
compared to fiscal 1993, due to an increase in the number and size of grants
awarded to the Company.
 
EXPENSES
 
     Research and development expenses increased by approximately $1.4 million
or 12% in fiscal 1995 compared to fiscal 1994 and increased by approximately
$1.5 million or 14% in fiscal 1994 compared to fiscal 1993. The increase in
fiscal 1995 was due principally to the start during 1994 of the additional
research program with HMRI, the expansion and extension of the Wyeth agreement
and the increase in activities related to the Company's proprietary programs in
the area of medicinal and natural products chemistry and clinical development of
TGF-[BETA]3 for oral mucositis.
 
     The increase in fiscal 1994 was due to an increase in expenditures in the
collaborative programs with MMDI and the commencement of the additional program
with HMRI, and increased research and development expenses incurred in
connection with the Company's proprietary and grant programs.
 
     Research and development expenses reimbursed by collaborative partners and
government research grants aggregated approximately $12.4 million, $11.1 million
and $10.3 million for fiscal years 1995, 1994, and 1993, respectively.
 
     Production expenses decreased approximately $175,000 or 12% for fiscal 1995
as compared with fiscal 1994, reflecting the sale of the Research Products
Business. Production expenses remained approximately constant in fiscal 1994
compared to fiscal 1993.
 
     Selling, general and administrative expenses decreased approximately
$347,000 or 5% in fiscal 1995 compared to fiscal 1994. This decrease reflected
the reduction in sales and marketing expenses due to the sale of the Research
Products Business, offset by increases in professional fees related to corporate
development activities. Selling, general and administrative expenses increased
approximately $1.1 million or 16% in fiscal 1994 compared to fiscal 1993. This
increase was principally attributable to expenses incurred in the Company's
international operations including a subsidiary in France engaged in the sale of
research products, as well as increased payroll and consulting expenses. In
connection with the sale of the Research Products Business, the Company elected
to close down the operations of its French subsidiary. Costs associated with the
close down have been offset against the gain on the sale of the Research
Products Business.
 
     Amortization of intangibles in fiscal 1995, 1994, and 1993 represents
amortization of patents and goodwill that resulted from the acquisition of the
cancer diagnostics business of Applied bioTechnology. The decrease in
amortization expense in fiscal 1995 is due to the portion of goodwill which was
expensed in connection with the sale of the Research Products Business.
 
                                       21
   22
 
OTHER INCOME AND EXPENSE
 
     Net investment income decreased approximately $24,000 or 3% for fiscal 1995
compared to fiscal 1994. Interest income earned in fiscal 1995 was higher than
in fiscal 1994 despite a lower average principal balance in fiscal 1995 due to
increased interest rates. However, this was offset in part by a net realized
loss on the sale of certain investments.
 
     Net investment income decreased approximately $72,000 or 8% for fiscal 1994
compared to fiscal 1993. This decrease was a result of declining interest rates
and decreased principal balance invested.
 
     The Company sold its Research Products Business to Calbiochem-Novabiochem
International, Inc. in August 1995 for $6.0 million in cash and other
considerations. The net gain on the sale was approximately $2.7 million.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
     In March 1995, Statement of Financial Accounting Standards (SFAS) No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of" was issued which establishes accounting standards for the
impairment of long-lived assets, certain identifiable intangibles, and goodwill
related to those assets to be held and used and for long-lived assets and
certain intangibles to be disposed of. SFAS No. 121 requires that long-lived
assets and certain intangibles to be held and used by an entity be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of the asset may not be recoverable. SFAS No. 121 must be
implemented no later than fiscal 1997. The adoption of SFAS No. 121 is not
expected to have material impact on the Company's consolidated financial
position or operating results.
 
     In October 1995, SFAS No. 123, "Accounting for Stock-Based Compensation",
was issued which establishes financial accounting and reporting standards for
stock-based employee compensation plans. SFAS No. 123 defines a fair value based
method of accounting for an employee stock option or similar equity instrument
and encourages all entities to adopt that method of accounting for all of their
employee stock compensation plans. However, SFAS No. 123 would permit the
Company to continue to measure compensation costs for its stock option plans
using the intrinsic value based method of accounting prescribed by APB Opinion
No. 25, "Accounting for Stock Issued to Employees". If the Company elected to
remain with its current accounting, the Company must make pro forma disclosures
of net income and earnings (loss) per share as if the fair value based method of
accounting had been applied. SFAS No. 123 must be implemented no later than
fiscal 1997. The Company has not yet determined the valuation method it will
employ or the effect on operating results of implementing SFAS No. 123.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At December 31, 1995, working capital (representing primarily cash, cash
equivalents and short-term investments) aggregated approximately $25.3 million.
 
     The Company has been, and will continue to be, dependent upon collaborative
research revenues, government research grants, interest income and cash balances
until products developed from its technology are commercially marketed. In April
1995, Ciba purchased 909,091 shares of the Company's common stock for an
aggregate purchase price of $5.0 million.
 
     During 1995, the pharmaceutical operations of Hoechst, Hoechst Roussel and
MMDI were consolidated into HMRI. The Company is aware that HMRI is conducting a
review of all its research and development programs. Based on discussions with
HMRI, the Company expects its programs with HMRI to continue under one overall
agreement in the future, although there can be no assurance that the Company and
HMRI will enter into such an agreement, or if such an agreement is entered into,
that it will not be on terms less favorable than the existing agreements with
each of Hoechst, Hoechst Roussel and MMDI. The Company anticipates that the
total funding under the consolidated agreement will be somewhat lower than the
aggregate level of funding under the three previously separate agreements.
 
                                       22
   23
 
     Since its commencement in 1991 and until the second quarter of fiscal 1995,
the cancer diagnostics collaborative program with Becton has focused on both
serum-based and histochemical immunoassays. During the second quarter of fiscal
1995, Becton decided to focus exclusively on cellular cancer diagnostics,
including histochemical immunoassays. Becton has reduced its funding under this
program in fiscal 1996, and the Company is uncertain as to Becton's ongoing
support for this program. The Company is continuing the development of
serum-based cancer diagnostic products and is in discussions with possible new
collaborative partners in this area. However, there can be no assurance that the
development of these tests will not be terminated.
 
     The Company believes that with the funding from its collaborative research
programs, government research grants, interest income, and cash balances, the
Company's financial resources are adequate for its operations through fiscal
1999. However, the Company's capital requirements may vary as a result of a
number of factors, including competitive and technological developments, funds
required for expansion of the Company's technology platform, including possible
joint ventures, collaborations, and acquisitions, the time and expense required
to obtain governmental approval of products, and any potential indemnification
payments to the purchaser of the Research Products Business, some of which
factors are beyond the Company's control. The Company intends to substantially
increase its expenditures and capital investment over the next several years to
enhance its drug discovery technologies and pursue internal proprietary drug
discovery programs. There can be no assurance that scheduled payments will be
made by third parties, that current agreements will not be cancelled, that
government research grants will continue to be received at current levels or
that unanticipated events requiring the expenditure of funds will not occur.
Further, there can be no assurance that the Company will be able to obtain any
additional required funds, or, if such funds are available, that such funds will
be available on favorable terms. Failure to obtain additional funds when
required would have a material adverse effect on the Company's business,
financial condition and result of operations.

                          INDEPENDENT AUDITORS' REPORT
 
The Stockholders
  and Board of Directors
Oncogene Science, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Oncogene
Science, Inc. and subsidiaries as of September 30, 1995 and 1994, and the
related consolidated statements of operations, stockholders' equity and cash
flows for each of the years in the three-year period ended September 30, 1995.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Oncogene
Science, Inc. and subsidiaries at September 30, 1995 and 1994, and the results
of their operations and their cash flows for each of the years in the three-year
period ended September 30, 1995 in conformity with generally accepted accounting
principles.
 
     During fiscal 1994, the Company changed its method of accounting for income
taxes and marketable securities to adopt the provisions of the Statements of
Financial Accounting Standards No.109, "Accounting for Income Taxes", and
No.115, "Accounting for Certain Investments in Debt and Equity Securities",
respectively.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 YEARS ENDED SEPTEMBER 30, 1995, 1994 AND 1993
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a) Principles of Consolidation
 
     The consolidated financial statements of the Company include the accounts
of Oncogene Science, Inc. and its wholly owned subsidiaries Applied
bioTechnology, Inc. and Oncogene Science S.A., a foreign subsidiary. All
intercompany balances and transactions have been eliminated. The Company is
engaged in the research and development of biopharmaceutical products for the
treatment and diagnosis of cancer, cardiovascular and other human diseases
associated with abnormalities of cell growth and control.
 
  (b) Revenue Recognition
 
     Collaborative research revenues represent funding arrangements for the
conduct of research and development ("R&D") in the field of biotechnology and
are recognized when earned in accordance with the terms of the contracts and the
related development activities undertaken. Other research revenues are
recognized pursuant to the terms of grants which provide reimbursement of
certain expenses related to the Company's other R&D activities. Collaborative
and other research revenues are accrued for expenses incurred in advance of the
reimbursement and deferred for cash payments received in advance of
expenditures. Such deferred revenues are recorded as revenue when earned. (See
Note 3)
 
     Revenue from the sale of diagnostic and research reagent products is
recognized at time of shipment.
 
  (c) Patents and Goodwill
 
     As a result of the Company's research and development programs, including
programs funded pursuant to the research and development funding agreements (See
Note 4), the Company has applied for a number of patents in the United States
and abroad. Such patent rights are of significant importance to the Company to
protect products and processes developed. Costs incurred in connection with
patent applications for the Company's research and development programs have
been expensed as incurred.
 
     Patents and goodwill acquired in connection with the acquisition of Applied
bioTechnology's cancer business in October 1991, have been capitalized and are
being amortized on a straight-line basis over the remaining lives of the
respective patents, and over five years for goodwill. The Company continually
evaluates the recoverability of its intangible assets by assessing whether the
amortized value can be recovered through expected future results.
 
  (d) Research and Development Costs
 
     Research and development costs are charged to operations as incurred and
include direct costs of research scientists and equipment and an allocation of
laboratory facility and central service. In fiscal years 1995, 1994, and 1993
R&D activities include approximately $5,695,740, $3,516,000, and $3,012,000, of
independent R&D, respectively. Independent R&D represents those research and
development activities, including research and development activities funded by
government research grants, substantially all the rights to which the Company
will retain. The balance of research and development represents expenses under
the collaborative agreements funded by Pfizer Inc. (Pfizer), Becton Dickinson
and Co.(Becton), Wyeth-Ayerst, a division of American Home Products (Wyeth),
Marion Merrell Dow Inc. (Marion), Hoechst AG and Hoechst-Roussel. On July 18,
1995, Marion, Hoechst AG and Hoechst-Roussel merged forming a new company named
Hoechst Marion Roussel Inc. (HMRI). The Company believes all of the Hoechst
collaborative agreements will continue under HMRI.

                 YEARS ENDED SEPTEMBER 30, 1995, 1994 AND 1993
 
  (e) Inventories
 
     Inventories represent principally diagnostics and research reagent products
and are stated at the lower of standard costs (approximating average costs) or
market. During fiscal 1995, the Company sold the business and certain assets,
including inventory, of the Research Products Business. (See Note 3)
 
  (f) Depreciation and Amortization
 
     Depreciation of equipment is provided over the estimated useful lives of
the respective asset groups on a straight-line basis. Leasehold improvements are
amortized on a straight-line basis over the lesser of the estimated useful lives
or the remaining term of their lease.
 
  (g) Income Taxes
 
     Effective October 1, 1993, the Company adopted the provisions of Statement
of Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS
No. 109"). SFAS No. 109 requires that the Company recognize deferred tax
liabilities and assets for the expected future tax consequences of events that
have been included in the financial statements or tax returns. Under SFAS No.
109, deferred tax liabilities and assets are determined on the basis of the
difference between the tax basis of assets and liabilities and their respective
financial reporting amounts ("temporary differences") at enacted tax rates in
effect for the years in which the differences are expected to reverse.
 
     The adoption of SFAS No. 109 did not have any impact on the financial
position or results of operations of the Company. The Company, in years prior to
fiscal 1994, accounted for income taxes in accordance with Accounting Principles
Board Opinion No. 11, "Accounting for Income Taxes."
 
  (h) Loss Per Share
 
     Loss per common share is computed by dividing the net loss by the weighted
average number of common shares outstanding. Common share equivalents (stock
options) are not included in the computation since their inclusion would be

  (i) Cash and Cash Equivalents
 
     The Company includes as cash equivalents reverse repurchase agreements,
treasury bills, and other time deposits with original maturities of three months
or less.
 
(2) INVESTMENTS
 
     The Company invests its excess cash in U.S. Government securities and debt
instruments of financial institutions and corporations with strong credit
ratings. The Company has established guidelines relative to diversification of
its cash investments and their maturities that should maintain safety and
liquidity. These guidelines are periodically reviewed and modified to take
advantage of trends in yields and interest rates. The Company uses the specific
identification method to determine the cost of securities sold.
 
     The Company adopted SFAS No. 115, "Accounting for Investments in Certain
Debt and Equity Securities," (SFAS No. 115) as of October 1, 1993. SFAS No. 115
requires securities classified as available for sale to be recorded at estimated
fair value. The Company's short-term investments, which include United States
Treasury obligations and corporate debt securities with original maturities in
excess of one year, are classified as securities available for sale based upon
management's current investment policy. Such investments, prior to the adoption
of SFAS No. 115, were recorded at the lower of cost or estimated market value
with aggregate declines in market value below amortized cost charged against
earnings. Under SFAS No. 115,

  (b) Contingencies
 
     The Company has received several letters from other companies and
universities advising the Company that various products being marketed and
research being conducted by the Company may be infringing on existing patents of
such entities. These matters are presently under review by management and
outside counsel for the Company. Where valid patents of other parties are found
by the Company to be in place, management will consider entering into licensing
arrangements with the universities and/or other companies or discontinuing the
sale or use of any infringing products. Management believes that the ultimate
outcome of these matters will not have a material adverse effect on the
financial position of the Company.

                 YEARS ENDED SEPTEMBER 30, 1995, 1994 AND 1993
 
based on age and service requirements. These benefits are subject to
deductibles, co-payment provisions and other limitations.
 
     The Company utilizes SFAS No. 106, "Employer's Accounting for Post
Retirement Benefits Other Than Pensions" to account for the benefits to be
provided by the plan. Under SFAS No. 106 the cost of post retirement medical and
life insurance benefits is accrued over the active service periods of employees
to the date they attain full eligibility for such benefits. As permitted by SFAS
No. 106, the Company elected to amortize over a 20 year period the accumulated
post-retirement benefit obligation related to prior service costs.
 
     Net post-retirement benefit cost includes the following components:
 


                                                           1995         1994         1993

    Service cost for benefits earned during the
      period...........................................  $107,175     $ 65,830     $ 70,867
    Interest cost on accumulated post-retirement

     The accrued post-retirement benefit cost at September 30, 1995 and 1994
were as follows:
 


                                                                     1995          1994
                                                                   ---------     ---------
                                                                           
    Accumulated post-retirement benefit obligationfully eligible

    Unrecognized transition obligation...........................   (302,717)     (320,266)
                                                                   ---------     ---------
    Accrued post-retirement benefit cost.........................  $ 366,203     $ 188,443
                                                                   =========     =========

 
     The accumulated post-retirement benefit obligation was determined using a
discount rate of 7.5 percent and a health care cost trend rate of approximately
12 percent decreasing to 6 percent in year 1999 and thereafter for 1995 and
1994. Increasing the assumed health care cost trend rates by one percentage
point in each year and holding all other assumptions constant would increase the
accumulated post-retirement benefit obligation as of September 30, 1995 and 1994
by approximately $106,000 and $94,000 respectively.

SECTION 16 REPORTING

         Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's officers and directors, and persons who own more than ten percent
of a registered class of the Company's equity securities, to file reports
of ownership and changes in ownership with the Securities and Exchange
Commission ("SEC").  Officers, directors and greater than ten percent
stockholders are required by SEC regulations to furnish the Company with
copies of all Section 16(a) forms they file.

         Based solely on the Company's review of such forms received by it,
or written representations from certain reporting persons that no Forms 5 were
required for such persons, the Company believes that, during the fiscal
year ended September 30, 1995, all filing requirements applicable to its
officers, directors and greater than ten percent beneficial owners were
complied with, except for the following: (i) with respect to a transaction by
Mr. French, no Form 4 was filed; and (ii) certain initial holdings of Dr.
Goddard were reported late.

ITEM 13.         CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Walter M. Miller, a director of the Company, is an officer of Becton.
See "Compensation Committee Interlocks and Insider Participation" for a
description of the Company's relationship with Becton.

     Mr. John P. White, a director of the Company, is a partner of Cooper &
Dunham, a New York City law firm specializing in patent, trademark and related
intellectual property matters. In fiscal year 1995, the Company paid or
accrued professional fees to Cooper & Dunham in an aggregate amount of $376,759.
 
     Mr. G. Morgan Browne, a director of the Company, is the Administrative
Director of the Cold Spring Harbor Laboratory ("CSHL"). In fiscal year 1995, the
Company paid or accrued fees to CSHL in an aggregate amount of $120,500, for
funding under a corporate sponsorship program and license fees.
 
     In July 1995, the pharmacentical operations of Hoechst, Hoechst Roussel
and MMDI were combined into one entity, HMRI. Prior to this date the Company had
collaborative agreements with all three of these companies (the "Predecessor
Agreements"). HMRI has succeeded to the Predecessor Agreements. In the
transaction described above, HMRI acquired 1,090,909 shares and a warrant to
purchase an additional 500,000 shares, of the Company's common stock, which
were formerly held by MMDI. Under the Predecessor Agreements, HMRI has been
granted certain exclusive, worldwide licenses by the Company, and has the
right to negotiate with the Company within specified parameters to obtain
certain other exclusive, worldwide licenses with respect to products resulting
from the joint research programs. In consideration for these licenses, HMRI will
pay royalties to the Company on sales of such products. In fiscal year 1995,
the Company earned an aggregate of $3.4 million in research funding under the
Predecessor Agreements. The Company and HMRI are currently in negotiations
with respect to a new agreement that would consolidate the Predecessor
Agreements. The terms of this prospective agreement are not yet determined, but
the Company anticipates that the level of annual funding under the new
agreement would be reduced compared to the total annual funding under the
Predecessor Agreements. There can be no assurance, however, that the Company and
HMRI will successfully negotiate a new agreement on terms favorable to the
Company, or at all. Failure to secure this agreement could have a material
adverse effect on the Company's business, financial condition and results of
operations.
