ITEM 1.        BUSINESS

INTRODUCTION

               Ecogen Inc. ("Ecogen" or the "Company"), a Delaware corporation
incorporated in 1983, is a biotechnology company specializing in the
development and marketing of environmentally compatible products for the
control of pests in agricultural and related markets.  Ecogen's product
revenues are generated by sales of biological insecticides derived from the
bacterial microorganism Bacillus thuringiensis ("Bt"), various pest control and
crop pollination products based on pheromone and related technologies, and
biological fungicide products for the control of powdery mildew and
post-harvest rot disease.  In addition, Ecogen is developing for introduction
into certain niche markets insecticidal nematodes (microscopic roundworms) for
the control of insect pests.  Ecogen was the first company to sell genetically
enhanced biological pesticide products which are registered with the United
States Environmental Protection Agency (the "U.S. EPA") for commercial sale.
In addition, Ecogen is the only company to have received U.S. EPA approvals to
sell Bt insecticides incorporating a recombinant Bt strain.

               On January 24, 1996, the Company entered into a strategic
alliance with Monsanto Company ("Monsanto") for the joint development of Bt
technology.  As part of the transaction, Monsanto agreed to purchase 943,397
shares of the Company's common stock for $10 million, acquired certain rights
with respect to Ecogen's Bt technology for $5 million and agreed to fund a
four-year $10 million research and development program.

               On January 29, 1996, the stockholders of the Company approved an
amendment to the Company's Certificate of Incorporation that effected a
one-for-five reverse stock split of the Company's outstanding common stock (the
"Reverse Split").  As a result of the Reverse Split, the outstanding shares of
common stock of the Company were reduced from approximately 30,109,000 to
6,022,000.  All references in this document to shares of common stock take into
account the effect of the Reverse Split unless the context otherwise requires.

               On December 28, 1994, the Company changed its fiscal year end
from December 31 to October 31 so that its fiscal year would better conform to
the agricultural growing season in its primary markets.  Unless the context
otherwise requires, all references in this document to the year 1996 shall mean
fiscal year 1996 beginning on November 1, 1995 and ending on October 31, 1996,
all references to the  year 1995 shall mean fiscal year 1995 beginning on
November 1, 1994 and ending on October 31, 1995, and all references to fiscal
1994 shall mean the ten months beginning on January 1, 1994 and ending on
October 31, 1994.

TECHNOLOGY

               Many naturally-occurring organisms are either antagonistic to or
produce substances toxic to agricultural pests.  These include a variety of
microorganisms such as bacteria, yeast, fungi, viruses and protozoans that
either directly kill or produce compounds that interfere with certain insects,
fungal pathogens or plant disease organisms.  In addition, more complex
organisms such as insecticidal nematodes (microscopic roundworms) that attack
insect pests have been long recognized as a potential source of pest control.
Insect pheromones, which are natural odors emitted by insects, are also a
recognized source of environmentally compatible, biorational insect pest
control.  All of these natural agents when isolated and formulated as
commercially useful products are commonly called "biopesticides."





                                       3
<PAGE>   4


     Bacillus thuringiensis ("Bt")

               Bt is a bacterium found in soil.  The insecticidal activity of
Bt derives from production of spores and specific proteins in the form of
crystals found within the Bt bacteria.  These insecticidal agents are produced
by the bacterial cells during a fermentation production process.  They are then
formulated into products that are applied to plants by conventional ground and
aircraft spray equipment.  When susceptible insects feed on plant foliage
sprayed with Bt-based products, the crystals are ingested and generate soluble
proteins that attack and destroy the insect's intestinal tract.  The proteins
produced by various strains of Bt are highly active against specific, targeted
insect pests.  Many insects are also susceptible to bacterial spores.  Bt has
no adverse activity against non-target insects, fish, birds or mammals
(including humans).  The genes for the insecticidal proteins reside on specific
non-essential DNA molecules termed plasmids.  Bt bacteria in nature generally
contain several different genes that endow different insecticidal activities.
Plasmids can either be removed ("cured") from cells that harbor them or they
can be transferred between different strains by a natural mating process called
conjugal transfer that occurs in nature between Bt strains and that can be
replicated in the laboratory.

               Ecogen has developed, through genetic modification techniques,
novel Bt bioinsecticide products that have higher levels of effectiveness and
that can act against a broader array of significant insect pests than Bt
products previously in use.  Ecogen has developed and characterized
approximately 10,000 Bt strains and maintains one of the world's largest
collections of Bt strains. The Company uses strains from this collection to
screen and test for insecticidal activities.  The characterization of the
diversity of Bt insecticidal proteins found in Ecogen's strain collection,
coupled with the ability to transfer or cure plasmids that contain the genetic
code for those proteins, was the basis for Ecogen's early-stage development of
new Bt bioinsecticides.  Potent insecticidal crystal proteins produced by new
Bt strains containing novel and desirable combinations, which are obtained by
plasmid curing and conjugal transfer techniques, have been the active
ingredients in Ecogen's Bt bioinsecticides.

               These natural genetic approaches to Bt bioinsecticide
development can be applied, however, only to those plasmids that can be
transferred or cured.  Certain insecticidal proteins are encoded by plasmids
that are not transferable, and some plasmid combinations are unstable or yield
undesired insecticidal activities.  Under these circumstances, the development
of genetically manipulated strains of Bt having novel activities against
specific insects is greatly facilitated by the application of recombinant DNA
technology.  Ecogen has developed a proprietary Bt-based cloning vector system,
its SSR System(TM), that utilizes recombinant DNA technology  to develop new Bt
strains having either increased potency or activity on a broader array of
insect species.  Ecogen believes that the use of Bt (as opposed to other
microorganisms) as the host microorganism in which new Bt insecticidal gene
combinations are constructed facilitates regulatory review in obtaining field
trial permission and subsequent registrations for recombinant-derived products.
For example, in July, 1992, Ecogen received a generic approval from the United
States Environmental Protection Agency to field test recombinant Bt
insecticides using this approach.  In February, 1996, the Company received U.S.
EPA approval to commercialize CRYMAX(TM) Bioinsecticide and in December, 1996,
the Company received U.S. EPA approval to commercialize Lepinox(TM)
Bioinsecticide, each of which is a recombinant Bt product based on a Bt strain
into which protein genes from different Bt strains were combined.  Ecogen's
genetically enhanced bioinsecticides contain multiple insecticidal genes and
have complex modes of action, and Ecogen therefore believes that pest
populations will have difficulty developing resistance to them.

               Ecogen has also developed technology to improve the insecticidal
capabilities of the Bt proteins through its work on the mechanisms involved in
the insecticidal activity.  This technology, collectively referred to as
Mechanism Assisted Insecticidal Design, permits Ecogen to move beyond naturally
occurring proteins to identify new and commercially valuable proteins.

     Pheromone and Crop Pollination Technology

               Insect pheromones are natural odors emitted by insects that are
undetectable to humans.  Pheromones and related technologies act as behavior
modifying agents that can be used to suppress insect mating by disrupting
communications between potential mates, to attract target insects or to
stimulate foraging by target insects.

               Pheromones can be used either alone to control insect
populations or in conjunction with biological or chemical insecticides in order
to reduce the amount of such insecticides required to control insect pests.
Pheromone products may be used to disrupt insect mating cycles.  These
products, which duplicate the mating attractant emitted by female insects,
control insect populations by making it more difficult for male insects to find
females with which to mate.  After application of the pheromone product, male
insects become confused and are attracted to the pheromone products rather than
potential mates.  In addition, the mating attractant of the pheromone product
camouflages the natural attractant emitted by the female which also works to
disrupt the mating cycle and to control insect populations.  Pheromones can
also be used to attract insects to trap devices for the purpose of monitoring
insect  populations or to sources of chemical insecticides that are lethal to
the target insects.

               Crop pollination technology is designed to attract honey bees to
crops to increase plant quality and grower yields through increased
pollination.  Products incorporating this technology assist honey bees in
finding plants, thereby maximizing the number of visitations by such bees to
the flowers of various fruit and vegetable crops.  Fruit and vegetable quality
may be increased and grower yields may be optimized through such increased
pollination.  Ecogen's Bee-Scent(R) Attractant is based on this crop
pollination technology.

     Biofungicide Technologies

               Biofungicide technologies are based on naturally occurring
organisms such as fungi or yeast that can control harmful fungi that reduce
crop yields or infect crops after harvesting.  Ecogen focuses biofungicide
research and development efforts on two biofungicide technologies:
hyperparasitic fungi which kill other fungi, such as powdery mildews that
infect plant leaves, flowers and fruit; and a yeast formulation which protects
stored fruit from post-harvest rot pathogens.

               A fungal hyperparasite, Ampelomyces quisqualis, has been
identified that infects most, if not all, types of powdery mildews harmful to
agricultural  products.  Ecogen has obtained an exclusive license to this
hyperparasite.  Powdery mildew is a significant fungal disease affecting many
crops.  Special structures of the mildew penetrate the plant epidermal cells
and feed on cellular tissue, causing dwarfing of the plant and fruit and
cosmetic damage which is particularly undesirable on fresh produce.  Plants
severely infected with these pathogens have reduced yields.  Historically,
chemical fungicides have been used for the control of these fungal pathogens,
but these pathogens typically develop resistance to these chemical fungicides
over time.  In response to this market need, the Company developed its AQ10(TM)
Biofungicide, which is based on the fungal hyperparasite Ampelomyces
quisqualis, for use in an integrated pest management system with other
fungicide products to control powdery mildew.  AQ10 was the first biofungicide
registered by the U.S. EPA to protect crops from powdery mildew.

               Several non-antibiotic producing strains of yeast have been
found to control a number of post-harvest rot pathogens of citrus, pome fruits,
grapes and other fruits and vegetables.  The Company has incorporated a
selection of these strains into its Aspire(TM) Biofungicide.  Aspire, which may
be applied by processors and packers in a manner consistent with the method of
application of standard chemicals, provides control of post-harvest rot
pathogens.

     Insecticidal Nematodes

               Insecticidal or entomopathogenic nematodes are microscopic
roundworms that attack insect pests in the soil or in plant stems.
Insecticidal nematodes are not directly responsible for insect mortality, but
rather harbor bacteria that are released into and cause an infection of the
insect after nematode entry into the pest.  Normally, the insect dies within 48
hours after infection.  The natural characteristics of insecticidal nematodes
give nematode-based insecticides certain advantages over other insecticides.
For example, nematodes attack insect pests in the soil where approximately 90%
of insect pests spend at least a portion of their life cycle.  In addition,
insecticides using nematodes, which cause no adverse effects to humans, animals
or plants, are currently exempt from U.S. EPA pesticide regulations and, unlike
other insecticides, including other bioinsecticides, are subject to
significantly lower levels of regulation or are exempt from registration by
state agencies.

               Nematode product development is dependent on the implementation
of production technology developed at a pilot scale, particularly to obtain
higher yields at larger commercial scale production and to reduce the costs of
production.  In addition, current shelf life of the insecticidal nematode
products being developed by Ecogen is insufficient for widespread
commercialization.  Ecogen is exploring methods of formulating and preserving
the nematodes to further increase shelf life while maintaining the nematodes'
insecticidal capabilities, including the development of formulations that would
be stable at various temperatures.

RELATIONSHIP WITH MONSANTO

               On January 24, 1996, the Company closed a transaction with
Monsanto forming a strategic alliance for development of the Company's
proprietary Bt technology.

               Under the terms of the agreement, Monsanto purchased 943,397
shares of Ecogen common stock for $10.60 per share for an aggregate purchase
price of $10 million.  Monsanto is required to maintain its ownership position
in Ecogen stock during the term of the four-year Research and Development
Agreement between Ecogen and Monsanto and Monsanto is prohibited, for three
years after closing, from acquiring more than a 25% aggregate equity interest
in the Company without the prior consent of the Company. These restrictions,
however, terminate upon the occurrence of certain defined events relating to a
change of control of the Company.  Monsanto has certain registration rights
with respect to the shares of Company common stock.  In addition, Monsanto has
a right of first refusal to purchase securities from the Company so as to
maintain its percentage ownership interest in the Company.

               In addition, Monsanto acquired for $5 million certain rights to
Ecogen's existing Bt strain library and insecticidal crystal protein gene
library, and the intellectual property rights associated with such libraries
including certain patents and patent applications (the "Bt Technology").
Ecogen maintains rights to the Bt Technology for applications other than
in-plant uses.  Monsanto did not acquire any rights to Ecogen's fermentation
and formulation technology, Ecogen's insectary technology or Ecogen's
technology related to the movement of Bt genes from Bt and back into Bt without
foreign DNA.





                                       6
<PAGE>   7


               Monsanto and Ecogen also entered into a Research and Development
Agreement to perform research and development focusing on Bt Technology (the "R
& D Program").  Under the R & D Program, Monsanto will provide Ecogen with a
minimum of $10 million over four years, of which $3 million has been received
to date.  The results of the R & D Program will be owned by Monsanto and
licensed to Ecogen for use outside of in-plant applications.  Under the terms
of the agreements with Monsanto, Ecogen will also share in the
commercialization success of transgenic plants incorporating the Bt Technology.
Monsanto shall pay a  commercialization success fee based on sales and license
fees revenue received by Monsanto from products which incorporate the Bt
Technology or the results  from the R & D Program.

ECOGEN TECHNOLOGIES I INCORPORATED

               Between November, 1992 and January, 1993, Ecogen Technologies I
Incorporated ("ETech"), a company incorporated by but not then affiliated with
Ecogen, completed a private placement of 300 ETech units, each unit consisting
of four shares of common stock of ETech and 2,000 warrants, each to purchase
one share of common stock of Ecogen at a per share purchase price of $43.75 as
adjusted for the Reverse Split (the "Ecogen Warrants").  The Ecogen Warrants
may be exercised at any time prior to January 31, 1998, and the Ecogen Warrants
and the underlying shares of Ecogen common stock are freely tradable.

               ETech was formed to initiate or accelerate research and
development of certain products using technology exclusively licensed or
sublicensed by Ecogen to the subsidiaries of ETech.  The licensed rights
include the right to develop and commercialize insecticide products based on
technology for:  (i) the control of powdery mildew disease (AQ10
Bioinsecticide); (ii) the control of post-harvest rot disease on agricultural
crops (Aspire Biofungicide); (iii) the control of the European corn borer
insect, which affects corn production (Condor(R) G Bioinsecticide); (iv) the
control of black vine weevil, citrus weevil, wireworm and black cutworm
utilizing insecticidal nematodes; (v) the control of corn rootworm; and (vi)
the control of certain insects which cause damage to turf.  Ecogen has agreed
to commercialize and market products on behalf of ETech pursuant to various
Marketing Agreements that provide for Ecogen to receive a fee from ETech based
on product sales for Ecogen's commercialization and marketing activities.

               In January, 1995, the Company exchanged 822,400 shares of its
common stock for 854 shares of the common stock of ETech (approximately 70% of
the outstanding common stock of ETech).  As a result of this exchange, ETech is
a majority-owned subsidiary of Ecogen and its financial condition and results
of operations are included in the Company's consolidated financial statements.

United States primarily through traditional agricultural chemical distribution
channels consisting of large wholesale distributors and dealers which serve
extensive farm areas.  Ecogen makes use of these traditional channels for the
domestic distribution of its current products.  To coordinate these
distribution activities and generate grower interest in its products, the
Company employs a marketing staff including several domestic sales
representatives who are located in key agricultural chemical distribution
locations, primarily in the southern and western areas of the United States.
In April, 1996, the Company entered into a distribution agreement for its
Aspire Biofungicide product with Decco, a business unit of Elf Atochem North
America, Inc.  Under the terms of the agreement, Decco will distribute Aspire
to fruit packinghouses, primarily in the United States.  Ecogen's domestic
product sales for fiscal 1996, fiscal 1995 and the ten months of fiscal 1994
totaled $7.0 million, $8.4 million and $7.7 million, respectively.

               For the international distribution of its products, Ecogen has
entered into several collaborations with companies that have a significant
presence in the markets covered by their respective agreements.  In 1991, the
Company and Hoechst Schering AgrEvo, S.A. ("AgrEvo") entered into a
distribution and product supply agreement that grants to AgrEvo exclusive
distribution rights to certain of the Company's primary Bt products in Europe
(except Germany, which is excluded, and Spain, Portugal and Italy, where rights
are co-exclusive), Africa, the People's Republic of China, Australia, the
Middle East and Latin America (except Mexico).  In addition to its agreement
with AgrEvo, Ecogen has international distribution agreements for certain of
its products with a number of other companies including: Green Marketing
International (for the Republic of South Africa), Nissan Chemical (for Japan),
Intrachem (International) S.A. (for Italy, Spain and Portugal), ISK Biotech
Corporation (for Mexico), Jia Non Enterprises (for Taiwan) and Incitec Ltd.
(for Australia and New Zealand).  International product sales totaled $1.6
million for fiscal year 1996, $716,000 for fiscal year 1995 and $897,000 for
the ten months of fiscal 1994.

PRODUCTION

               The manufacturing process for Ecogen's Bt-based bioinsecticide
and biofungicide products involves fermentation of the desired microorganism.
Upon completion of this fermentation process, the pesticidal agent is recovered
using standard techniques, such as centrifugation, and is formulated into
commercial products.  Ecogen operates a fermentation and formulation pilot
plant to support some product requirements for field trials and to facilitate
the transition of products from laboratory to large-scale manufacturing.  For
commercial production of its products, Ecogen generally engages third party
contract manufacturers to perform one or more steps in the manufacturing
process for the Company's products.

               Ecogen is a party to an arrangement with Archer Daniels Midland
Company ("ADM") pursuant to which ADM will manufacture Ecogen's Bt-based
insecticides as well as Aspire Biofungicide at ADM's facility in Decatur,
Illinois.  This facility has both fermentation and formulation capability and
is designed to supply Ecogen with finished goods of the Company's Bt products.
The current arrangement with ADM resulted from ADM's guarantee of the
performance of Ecogen's prior supplier, biosys, Inc., which filed a bankruptcy
petition in September, 1996.  Ecogen believes that adequate fermentation,
formulation and other services are available from other contract manufacturers,
but the engagement of such other contract manufacturers may cause at least
short-term disruptions of the Company's manufacturing.

               The Company purchases the active ingredients for its pheromone
products from various suppliers and manufactures its pheromone products at its
facility in Billings, Montana.  In  addition, the Company obtains certain
manufacturing services from 3M Corporation with respect to the formulation of
some of its NoMate products.  The Company believes that its Billings, Montana
facility has sufficient capacity to meet its current and near-term anticipated
pheromone product needs.

               The most important raw materials needed by Ecogen to conduct its
product manufacturing and research and development activities include both
fermentation media components and formulation chemicals, which are readily
available from a variety of independent sources, and microbial strains that are
either proprietary to Ecogen or are licensed from outside parties.  Ecogen does
not anticipate any shortages of these or other raw materials that would
materially affect product availability or cost.

RESEARCH AND PRODUCT DEVELOPMENT

               The Company's operating expenses to date have included costs
associated with the research and development of products for future
commercialization.  Costs incurred by Ecogen under third-party funded research
and development programs aggregated approximately $1.0 million for fiscal 1996,
$1.7 million for fiscal 1995 and $6.0 million for the ten months of fiscal
1994.  Costs incurred under Ecogen-funded research and development programs
aggregated approximately $3.9 million, $7.3 million and $3.3 million for fiscal
1996, 1995 and 1994, respectively.

               During fiscal 1996, the Company derived approximately 43% of its
revenues from research and development contracts and technology license
agreements.  This contrasts with approximately 24% in 1995 and 54% in 1994.

     Bacillus thuringiensis Products

               Ecogen's Bt product development activities are focused on
improving, through recombinant DNA and other technologies, the efficacy of its
bioinsecticides already in the market, adapting such products for application
to additional uses, and developing new bioinsecticides.  In addition, Ecogen is
attempting to improve its fermentation and formulation processes in order to
increase product yield and reduce the costs of product manufacturing.

     Pheromone and Related Products

               Ecogen is exploring additional formulations of its pheromone
products in order to develop alternative application techniques for such
products.  Tests also are being conducted by the Company in order to expand its
pheromone product line for the control of additional pests.

     Yeast, Fungal and Other Products

               The Company is continuing to develop processes for the commercial
production by fermentation of AQ10 and Aspire Biofungicides.  The Company is
also continuing to develop stable and efficacious formulations for these
products.  With respect to Aspire Biofungicide, the Company is working to
develop formulations that provide Aspire with increased shelf life at room
temperatures.  In addition, the Company is working on different types of
bacteria that may be used for the control of certain plant parasitic nematodes
that feed on or enter roots of growing plants causing damage and reduced crop
yields. In laboratory tests and greenhouse trials, Ecogen has identified
bacterial isolates with activity against root knot nematodes which attack a
variety of crop plants.

     Insecticidal Nematodes

               The Company is working to implement at a commercial scale
production technology developed at a pilot scale so as to obtain higher yields
and reduce the costs of production.  The Company is also investigating methods
for increasing the shelf life of nematode products (particularly at ambient
temperatures).  In addition, the Company is continuing the development of
formulations that are designed to make the Company's products easier to use and
to increase product shelf life.

PATENT AND TRADE SECRETS

               Ecogen pursues a policy of seeking patent protection, both in the
United States and abroad, to protect its novel technologies, compositions of
matter and processes.  With respect to the Company's two biofungicide products,
AQ10 Biofungicide and Aspire Biofungicide, and with respect to certain of its
Bt technology, the Company holds licenses to patents covering the base
technologies.

               There can be no assurance that patents or license rights under
patents for all of the Company's products and processes will be obtained, or
that issued patents will provide substantial protection or be of commercial
benefit to the Company.  The issuance of a patent is not conclusive as to its
validity or enforceability, nor does it provide the patent holder with freedom
to operate without infringing the patent rights of others.  A patent could be
challenged by litigation and, if the outcome of such litigation were adverse to
the patent holder, competitors could be free to use the subject matter covered
by the patent or the patent holder could be required to license the technology
to others.

               Because of the uncertainty concerning patent protection, the
Company relies, in certain cases, upon trade secret protection and continuing
technological innovation to maintain its competitive position.  All Ecogen
employees and consultants sign confidentiality agreements under which they
agree not to use or disclose the Company's confidential information as long as
that information remains proprietary or, in other cases, for fixed time
periods.  There can be no assurance, however, that such proprietary technology
will not be independently developed or that secrecy will not be breached.  The
Company's research, development and commercialization partners, as well as its
biopesticide production subcontractors, are provided access to know-how under
confidentiality agreements.  To the extent that such entities use this
technological information, disputes may arise as to the proprietary and patent
rights to such technological information and related developments.

               The Company is aware that substantial research efforts in
biotechnology are taking place at universities, government laboratories and
other corporations around the world and that numerous patent applications have
been filed, and patents have been issued, relating to fundamental technologies
and to specific biological pesticide products and processes.  The Company may
have to obtain licenses under certain of these patents.  No assurance can be
given concerning the terms on which such licenses would be available, if at
all.

GOVERNMENTAL REGULATION

               Regulation by governmental authorities in the United States and
other countries is a significant factor affecting the  success of products
resulting from biotechnological research.

               The pesticide industry is heavily regulated in the United States.
The U.S. EPA regulates pesticide products under the Federal Insecticide,
Fungicide and Rodenticide Act ("FIFRA").  Pesticides also are regulated by
various state agencies.  Some states, such as California, have their own
extensive registration requirements.  To develop and commercialize a pesticide
product, detailed and complex procedures must be followed and federal approvals
must be obtained under FIFRA.  Small-scale field testing usually may be
conducted prior to product registration to evaluate product efficacy.  To
conduct large-scale tests, a company must obtain an Experimental Use Permit
("EUP"), which generally requires satisfactory completion of certain





                                       11
<PAGE>   12


toxicology and environmental studies.  Synthetic chemical pesticides require
additional extensive toxicology and environmental testing that typically is not
required of biopesticides to substantiate product safety prior to obtaining a
product registration.  Commercial sale of a pesticide requires a registration
for each pest and crop for which the product is used.  Registration
requirements include submission and U.S. EPA approval of the text of a label
which must be included on every pesticide product.

               The United States Congress has mandated under the Food Quality
Protection Act of 1996 that all U.S. EPA tolerances be reassessed using new
standards within 10 years.  All tolerances will now be based on a "reasonable
certainty of no harm" and there will be a specific determination of risk to
infants and children.

               The U.S. EPA has recognized that biochemical and microbial
pesticides are distinguished from standard chemical pesticides and has
established different data requirements as part of its registration
regulations. These data requirements are set out in Subdivision M of the U.S.
EPA's Pesticide Assessment Guidelines.  Biopesticides currently are subject to
a three-tier toxicology testing procedure and a four-tier environmental testing
procedure.  A biopesticide product which satisfactorily completes both the Tier
I toxicology and environmental tests is not required to go through the tests
specified in subsequent tiers.  This has been the case for product registration
applications filed by the Company to date.  However, should questions arise
during any tier of testing, additional tests may be required.  For a
biopesticide product required to complete only Tier I testing, approximately
one year of laboratory testing is required.  Subsequent U.S. EPA registration
generally takes approximately one year.  Although the process for obtaining
regulatory approval to test and market biopesticides that are genetically
modified is designed to be less complex and time-consuming than the regulatory
approval process for synthetic chemical pesticides, there can be no assurance
that approvals will be granted on a timely basis, if at all.

               Certain of Ecogen's products under development utilize
recombinant DNA technology.  The Federal government regulates certain
recombinant DNA research activity through the National Institute of Health's
Guidelines for Research Involving Recombinant DNA Molecules ("NIH Guidelines").
The NIH Guidelines, among other things, set laboratory procedures and establish
levels of biological and physical containment and other standards for
recombinant DNA molecules that must be met for various types of research.
Ecogen believes that it is in compliance with the NIH Guidelines.  In August,
1992, Ecogen received blanket permission from the U.S. EPA to conduct
small-scale field trials of its recombinant Bt strains without prior notice
(generally required for small-scale field testing of microbial pesticides).

               Pheromone and related products (other than trap and lure
products) generally require U.S. EPA and state registrations.

               Insecticidal nematodes are currently exempt from registration
under U.S. EPA pesticide regulations and, unlike other insecticides, including
other bioinsecticides, are subject to significantly lower levels of regulation
or are exempt from registration by state agencies.

               Ecogen's activities, including operation of its laboratories and
pilot-scale manufacturing facilities, are, or may be, subject to regulation (i)
under various other state and federal laws and regulations, including the
Occupational Safety and Health Act, the Toxic Substances Control Act, the
Federal Food, Drug and Cosmetic Act, the Solid Waste Disposal Act, the Resource
Conservation and Recovery Act, the Emergency Planning and Community
Right-to-Know Act, the Clean Air Act, the Clean Water Act, and other state and
federal laws regulating





                                       12
<PAGE>   13


environmental quality, and the implementation of regulations for all such laws;
and (ii) by other state and federal agencies, including the U.S. Department of
Agriculture and the U.S. Food and Drug Administration.  In addition, the
actions of federal agencies in reviewing applications by Ecogen or issuing
permits or other authorizations may be subject to the National Environmental
Policy Act, and state or local agencies may be required to comply with similar
state laws.  Historically, the cost of compliance with such laws and
regulations has not had a material impact on Ecogen's business.

               From time to time, governmental authorities review the need for
additional laws and regulations for biotechnology products and for pesticide
products that could, if adopted, apply to the business of Ecogen.  Ecogen is
unable to predict whether any such new regulations will be adopted or whether,
if adopted, such regulations will adversely affect its business.

               Historically, the cost to Ecogen of compliance with federal,
state and local provisions enacted for the protection of the environment has
not been material.  Toxicology testing, field development trials and related
costs for U.S.  EPA registrations incurred to date by Ecogen have averaged
under $500,000 for each product registration, while state registration and
related costs per product have been nominal.  This does not mean that such
costs are unlikely to increase in the future, particularly if more restrictive
approval requirements are adopted by federal, state or local authorities.
Also, delays in obtaining necessary product registrations can have a
significant impact upon Ecogen's revenues and competitive position in the way
of delayed product sales and lost market opportunities.

               Field development and testing, as well as the commercial sale, of
Ecogen's biopesticide products outside the United States can be highly
regulated.  The impact of such regulation upon Ecogen's business cannot be
assessed at this time.

COMPETITION

               Competition in the pesticide market is intense.  Competition is
based principally on price and efficacy, but safety and ease of application are
also factors.  Competitors of Ecogen include manufacturers and marketers of
synthetic chemical pesticides and biopesticides, including large chemical
companies such as Abbott Laboratories, Novartis and DowElanco, as well as
specialized biotechnology firms.  Many of these companies have considerably
greater financial and marketing resources than Ecogen.  Competitors with
respect to research and development activities also include universities and
public and private research organizations.  In addition, Ecogen's
bioinsecticide products compete with certain transgenic seed and plant products
that have insecticidal capabilities.

               Ecogen believes that its ability to compete in the  pesticide
market may be enhanced by heightened concerns about the effects of chemical
pesticides upon the environment and, in some cases, by the increasing
resistance of plant pests to synthetic pesticides.  However, Ecogen expects
competition in the agricultural pesticide industry to intensify as technical
advances in the fields of pesticides and pest-resistant plants are made.  There
can be no assurance that developments by others will not render the Company's
products or technology obsolete or noncompetitive.

SEASONALITY

               The bulk of the Company's current products are presently marketed
for agricultural applications in the northern hemisphere, where the growing
season generally runs from spring until fall.  Commercial introduction of the
Company's new products is contingent upon, among other factors, completion of
field testing and receipt of required regulatory approvals.  Unusual weather
conditions during field tests or failure to receive regulatory approvals prior
to the growing season may require additional field tests in subsequent growing
seasons, with resulting delays in product development and commercialization. In
addition, because of the seasonal nature of its business, the Company's product
revenues are likely to be concentrated in the fiscal quarters prior to and
during a particular growing season and may result in substantial variations in
quarter-to-quarter financial results.  Product sales from year to year are also
affected by unusual weather conditions, such as droughts or floods, and the
level of insect infestation in grower areas.

EMPLOYEES

               As of January 3, 1997, Ecogen and its subsidiaries employed full
time 88 persons, of whom 16 hold Ph.D. degrees and 18 hold other advanced
degrees.  Doctoral degrees held by employees of Ecogen encompass the areas of
biochemical engineering, biochemistry, entomology, microbiology, molecular
genetics, physiology and plant pathology.

               Employees of the Company are required to enter into
confidentiality agreements with Ecogen.  Pursuant to these agreements, the
employees have agreed not to disclose Ecogen's proprietary information and to
assign to Ecogen all rights to any inventions made during their employment or
relating to Ecogen's activities, and not to engage in activities similar to
their activities at Ecogen for any other person or entity during the term of
their employment and for one year thereafter.  Ecogen believes that its
relationship with its employees is good.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION

               Ecogen is an agricultural biotechnology company specializing in
the development and marketing of quality biorational products for the control
of pests in agricultural and related markets.  On December 28, 1994, the
Company changed its fiscal year end from December 31 to October 31 so that its
fiscal year end would better conform to the agricultural growing season in its
primary markets.  Accordingly, in the discussion below, fiscal 1995 results
have been compared to results for a pro forma year ended October 31, 1994.  The
unaudited consolidated financial statements for the year ended October 31, 1994
are not presented separately herein.

OVERVIEW

               Total revenues increased 37% in fiscal 1996 to $ 16.4 million
from $ 12.0 million in fiscal 1995.  In fiscal 1996, product sales decreased
5.9% from $9.1 million in fiscal 1995 to $8.6 million in 1996. Gross margins
decreased to 34% in fiscal 1996 compared to 40% in fiscal 1995 due principally
to lower volumes and product mix.  Net loss before special charges decreased
from ($13.1) million in fiscal 1995 to ($2.7) million in fiscal 1996 as a
result of lower operating expenses and higher other revenue.  Other revenue
included $4.8 million in upfront payments from Monsanto in 1996 for the rights
to certain Bt technology.  The 1995 results included special charges of $10.2
million relating to purchased technology from ETech, the shutdown of Ecogen
Australia and other severance costs.  Net loss in fiscal 1995 was ($23.3)
million or ($4.34) per  share compared to ($2.7) million or ($.40) per share in
fiscal 1996.

The following is a summary of results as a percentage of total revenues, unless
otherwise indicated, as well as the percentage change in dollar amounts
compared to the prior period:

RESULTS OF OPERATIONS - YEAR ENDED OCTOBER 31, 1996 COMPARED TO YEAR ENDED
OCTOBER 31, 1995

     REVENUES

               Total revenues increased 37% in fiscal 1996 from $12.0 million to
$16.4 million, principally as a result of the Company's research and
development strategic alliance with Monsanto.  Net product sales decreased 6%
or $.5 million in fiscal 1996 compared to fiscal 1995.  The Company's product
sales did not increase in fiscal 1996 at the levels expected, principally as a
result of manufacturing equipment design issues which delayed certain new
product introductions and lower insect pressure in the Mississippi Delta in
late season cotton and southern soybeans.  The Company believes that the design
issues have been addressed and the Company expects to have the equipment
operating by the end of its first fiscal quarter which will allow the Company
to proceed with commercial scale-up of its new products in fiscal 1997.  Sales
of the Company's Bt product line, representing 15% of Company product sales,
decreased 29% in fiscal 1996 principally on lower sales volume due principally
to lower cotton acreage available for sprayable Bt insecticides and low insect
pressure in the Delta and in southern soybeans.  Bt product sales were ($.7)
million in the fourth quarter as a result of higher than expected returns of
Condor XL from the cotton market.  Sales of the pheromone product line,
representing 50% of total sales, increased 22% primarily due to increased
volume, including initial international sales of NoMate(R) CM for the control
of codling moth on apple trees, and increased sales of insect trap and lure
products pursuant to contracts with governmental entities.  Sales of
biofungicide products, representing 5% of total sales for fiscal 1996,
represented initial sales of the Company's first two biofungicide products,
AQ10 and Aspire, in fiscal 1996.

               Research contract revenues decreased 8% in fiscal 1996, due 
primarily to the divestiture of Ecogen Europe S.r.l., the Company's former
majority-owned European research subsidiary, partially offset by research
contract revenues resulting from the Company's research and development
strategic alliance with Monsanto.  License fees and other income increased $5.0
million principally as a result of the Company's strategic alliance with
Monsanto.  Interest income increased approximately $.2 million in fiscal 1996 as
a result of the increase in funds available for investment.

     COSTS AND EXPENSES

               Gross margins decreased to 34% for 1996 compared to 40% in fiscal
1995, primarily as a result of a change in product mix caused by higher
pheromone sales pursuant to lower margin government contracts, and higher
international sales which carry lower margins and  unabsorbed overhead charged
to costs of sales during the fourth quarter of 1996 as a result of a production
slow-down due to manufacturing equipment design issues.  As discussed above,
the Company believes that the design issues have been addressed and expects to
proceed with commercial scale-up of new products in 1997.

               Research and development costs decreased $4.0 million or 45%
principally as a result of cost savings from restructuring decisions made by
the Company in 1995, including the divestiture of Ecogen Europe S.r.l., other
reductions of research and development personnel, and a reduction in outside
consulting expenditures.  During the fourth quarter of 1996, the Company
recorded in research and development costs $.3 million in start-up expenses
associated with the scale-up of new products.  Selling, general and
administration expenses decreased $2.1 million or 20% principally as a result
of a reduction in personnel and other cost saving measures.

               Net loss for fiscal 1996 was ($2.7) million, or ($.40) per share,
compared with a net loss of ($23.3) million or ($4.34) per share in the same
period in fiscal 1995.  The 1995 fiscal year included special charges of $10.2
million principally due to the write-off of in-process research and development
as a result of the Company's acquisition of a controlling interest in ETech.
Net loss of





                                       19
<PAGE>   20


($2.7) million or ($.40) per share in fiscal 1996 represents a sharp decline
from the net loss exclusive of special charges of ($13.1) million or ($2.45)
per share in 1995 on weighted average shares of 7,149,000 and 5,373,000 in 1996
and 1995, respectively, due principally to cost reductions of $6.2 million
noted above and $5.0 million of other revenue.

RESULTS OF OPERATIONS - YEAR ENDED OCTOBER 31, 1995 COMPARED TO UNAUDITED PRO
FORMA YEAR ENDED OCTOBER 31, 1994

     REVENUES

               Total revenues decreased $10.9 million or 48% in fiscal 1995
compared to the same period in 1994 principally due to lower research contract
revenue as a result of the acquisition of ETech.  Product sales in 1995
approximated the same level as the comparable period in 1994.  Sales of Bt
products increased marginally due to volume increases in 1995 despite adverse
weather conditions in the Mississippi Delta, the Company's primary sales region
for its Bt product line.  Sales of the Company's pheromone product line
decreased 3% as a result of volume primarily due to economic uncertainties in
the Mexican market and  inventory carryover in the Pacific Northwest.  Gross
margins on product sales increased to 40% in 1995 from 31% in the same period
in 1994 in spite of the fact that pheromone product sales, other than pursuant
to government contracts, which generally have the highest gross margins,
decreased in 1995.  The increase in gross margins in 1995 reflects the
continuing impact of lower manufacturing costs due to improvements made to the
Bt manufacturing process.

     OPERATING COSTS

               Research and development costs decreased $3.0 million or 25.0%
in fiscal 1995 compared to the same period in 1994 due principally to scheduled
reductions in spending under ETech programs for which research effort had been
accelerated in 1993 and 1994 as a result of the ETech financing. Selling and
marketing expenses increased $.8 million or 18.5% as a result of costs
associated with the preparation for new product introductions.  General and
administrative expenses decreased $1.2 million or 17.6% in fiscal 1995 compared
to the same period in 1994 as a result of personnel reductions and other cost
containment measures taken in late 1994 and in 1995.

               Total operating expenses were $29.8 million during fiscal 1995
compared to $23.3 million in the same period in 1994.  The increase in
operating expenses was due to special charges of $10.2 million in 1995 that are
detailed below.  Operating expenses exclusive of special charges decreased 14%
from $22.9 million in fiscal 1994 to $19.6 million in the comparable period in
1995 due to the factors noted above.

               Net loss for fiscal 1995 was ($23.3) million or ($4.34) per
share compared to ($6.8) million or ($1.84) per share in the same period in
1994.  The net loss exclusive of special charges was ($13.1) million or ($2.45)
per share in 1995 compared to ($6.5) million or ($1.75) per share in 1994.  The
increase in net loss exclusive of special charges is due to the decrease in
research contract revenue partially offset by lower operating costs and higher
gross margins.

     SPECIAL CHARGES

The following represents a summary of special charges in 1995 (in thousands):

<PAGE>   21


               Restructuring costs include $.9 million of severance costs of
which $.3 million was paid in fiscal 1996 and $.2 million is payable in each of
fiscal 1997 and 1998.

SEASONALITY OF BUSINESS

               The bulk of the Company's current products are presently marketed
for agricultural applications in the northern hemisphere, where the growing
season generally runs from spring until fall.  Commercial introduction of the
Company's new products is contingent upon, among other factors, completion of
field testing and receipt of required regulatory approvals.  Unusual weather
conditions during field tests or failure to receive regulatory approvals prior
to the growing  season may require additional field tests in subsequent growing
seasons, with resulting delays in product development and commercialization. In
addition, because of the seasonal nature of the Company's business,  product
revenues are likely to be concentrated in the fiscal quarters prior to and
during a particular growing season and may result in substantial variations in
quarter-to-quarter financial results.  Product sales from year to year are also
affected by unusual weather conditions, such as droughts, and the level of
insect infestation in grower areas.

INFLATION

               To date and for the foreseeable future, inflation has not had nor
is it anticipated to have a significant impact on revenues or costs and
expenses of the Company, except to the extent of normal cost of living
adjustments related to personnel costs.

LIQUIDITY AND CAPITAL RESOURCES

               The Company has financed its working capital needs primarily
through private and public offerings of equity securities, research revenues
and license and other fees from research and development contracts and product
sales.

               At October 31, 1996, the Company had cash, cash equivalents and
temporary investments of $9.6 million, a net increase of $7.8 million from
October 31, 1995. Cash and cash equivalents increased $3.8 million and
investments increased $4.0 million. Such increases resulted primarily from
$11.4 million received from financing transactions in fiscal  1996 offset by
cash expenditures during the year of $3.1 million for operations, and $.5
million for the purchase of plant and equipment.

               During 1996, the Company completed the Monsanto transaction,
which resulted in an immediate cash infusion to the Company of $18.0 million
including $10 million in gross proceeds from the sale of 943,397 shares of the
Company's common stock.  Further, the  Company sold 122,000 shares of Series C
preferred stock at $25 per share in a  private placement to institutional
investors for aggregate net proceeds of $2.8 million, all of which converted to
common stock in fiscal 1996.  In connection with the private placement, the
Company issued warrants to purchase 77,877 shares of the Company's common stock
at $7.30 per share exercisable for five years.

               To date, the Company has not generated positive cash flow from
operations.  The Company believes that its existing working capital and cash
flow generated from total revenues in 1997 should be sufficient to meet its
capital and liquidity requirements for at least the next year based on reduced
spending levels, if necessary. The Company may need additional financing to
support current levels of product development and commercialization.  There is
no assurance that such financing will be available on terms acceptable to the
Company or at all.  Further, the  Company's working capital and working capital
requirements are affected  by numerous factors and there is no assurance that
such factors will not have a negative impact on the Company's liquidity.
Principal among these are the success of its product commercialization and
marketing efforts and the efforts of its strategic partners in commercializing
and selling products based on the Company's





                                       21

technology, the technological advantages and pricing of the Company's products,
economic and environmental  considerations which impact agricultural crop
production and the agricultural sector generally, competitive conditions in the
agricultural pest control market, and access to capital markets that can
provide the Company with the resources necessary to fund its strategic
priorities.  Over the long term, the Company's liquidity is dependent on market
acceptance of its products and technology.

               At October 31, 1996 the Company had commitments for capital
expenditures of $.4 million.

               Through October 31, 1996, the Company had available Federal net
operating loss carryforwards of approximately $63.7 million which expire at
various times through the year 2010.  In addition, the Company had research and
experimentation tax credits of approximately $2.4 million, which credits expire
at various times through the year 2010.

               As a result of certain equity transactions, the Company
experienced ownership changes as defined by rules enacted with the Tax Reform
Act of 1986 (the "Act").  Accordingly, the Company's ability to use its net
operating loss and research and experimentation credit carryforwards is subject
to certain limitations as defined by the Act.  The Company believes that such
limitations should not have a significant impact in 1997 or 1998 since
anticipated taxable profits, if any, will not exceed the amount of the
limitation.  In addition, to the extent that the Company recognizes gains, if
any, on the disposition of assets held on the date of the ownership change, the
annual limitation is increased by the amount of the "built-in" gains
attributable to those assets.  The built-in gain on a particular asset is the
excess of its fair market value over its cost basis on the date of the
ownership change.

OTHER ASSETS, LIABILITIES AND STOCKHOLDERS' EQUITY

               Inventory increased $.5 million principally as a result of lower
than expected Bt sales and increased purchases of certain raw materials offered
at favorable prices.  Accounts receivable increased $1.0 million principally as
a result of international sales on extended payment terms.  Prepaid expenses
and other current assets increased $.3 million due principally to accrued
income on the investment portfolio.

               Accounts payable increased $1.1 million as a result of increased
refunds due on product returns in October 1996 and amounts due for construction
in progress partially offset by the timing of payments on other trade payables.
Deferred contract revenue increased $1.1 million in fiscal 1996 as a result of
unearned advanced payments received from Monsanto pursuant to the Research and
Development Contract.

               Long-term debt and other long-term liabilities increased $.4
million in 1996 principally as a result of additions to capital leases.

               Stockholders' equity increased $8.9 million as a result of 1996
equity financings  offset by operating losses in 1996.

               In March, 1995, the Financial Accounting Standards Board (FASB)
issued 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," which is effective for fiscal years beginning after December 15,
1995.  This  standard is not expected to have a significant effect on either
the results of operations or financial position of the Company.

Discussions set forth by the Company in public documents including the Annual
Report contain forward looking statements that involve a number of risks and
uncertainties that could cause actual





                                       22
<PAGE>   23


results to differ materially from expected results.  The Company intends to
market and sell a number of newly introduced products.  Some of these products
utilize new formulations which have not to date been produced on a commercial
scale or produced on a commercial scale that has been replicated.  Certain of
the manufacturing processes for such products include newly developed equipment
and techniques which are being incorporated into commercial scale manufacturing
processes.  Risks and uncertainties associated with the successful
commercialization of the products include: (i) the successful scale-up of the
Company's manufacturing process in time to meet targeted sales opportunities;
(ii) the market acceptance of the Company's current and newly introduced
products; (iii) the efficacy, pricing, ease of use and performance of the
Company's products; (iv) the successful development, registration,
commercialization and marketing of technologically advanced new products; (v)
the continued and uninterrupted supply of the Company's products from
third-party toll manufacturers and the continued financial viability of such
manufacturers; (vi) economic and environmental considerations which impact
agricultural crop production and agricultural crop protection, including the
number of acres of target crops planted, the cost and efficacy of competitive
products, weather conditions and the level of insect and disease infestation on
target crops, and (vii) the ability of the Company to fund its strategic
priorities through operations or access to capital markets.

                          Independent Auditors' Report


The Board of Directors and Stockholders
Ecogen Inc.:


             We have audited the consolidated financial statements of Ecogen
Inc. and subsidiaries as listed in the accompanying index in Item 14.  In
connection with our audits of the consolidated financial statements, we also
have audited the financial statement schedule as listed in the accompanying
index in Item 14.  These consolidated financial statements and financial
statement schedule are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these consolidated financial
statements and financial statement schedule 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
Ecogen Inc. and subsidiaries as of October 31, 1996 and 1995, and the results
of their operations and their cash flows for the years then ended and the ten
months ended October 31, 1994, in conformity with generally accepted accounting
principles.  Also in our opinion, the related financial statement schedule,
when considered in relation to the basic consolidated financial statements
taken as a whole, presents fairly, in all material respects, the information
set forth therein.

                   Notes to Consolidated Financial Statements
                        October 31, 1996, 1995 and 1994


(1) Summary of Significant Accounting Policies

    Organization and business activities:
        The consolidated financial statements include the accounts of Ecogen
        Inc. ("Ecogen" or the "Company") and its wholly-owned and
        majority-owned subsidiaries.  All intercompany accounts and
        transactions have been eliminated in consolidation.

        The Company is a biotechnology company specializing in the development
        and marketing of environmentally compatible products for the control of
        pests in agricultural and related markets.  The Company has not yet
        achieved profitable operations and there is no assurance that
        profitable operations, if achieved, could be sustained on a continuing
        basis.  Further, the Company's future operations are dependent on,
        among other things, the success of the Company's commercialization
        efforts and market acceptance of the Company's products.

    Fiscal year end:
        In December 1994, the Company changed its year end from a calendar year
        end to a fiscal year ending October 31.  Accordingly, the accompanying
        consolidated financial statements include balance sheets at October 31,
        1996 and 1995 and statements of operations, cash flows, and
        stockholders' equity for the years ended October 31, 1996 and 1995, and
        for the ten months ended October 31, 1994.

    Inventory:
        Inventory is stated at the lower of cost, as determined by the average
        cost method, or net realizable value.

    Plant and equipment:
        Plant and equipment are recorded at cost.  Depreciation is computed by
        utilizing an accelerated method over the estimated useful lives of the
        related assets which range from three to ten years.  Amortization of
        leasehold improvements is computed using the straight-line method over
        the lesser of the estimated useful lives of the improvements or the
        remaining lease term.

    Research and development:
        All research and development costs are charged to operations as
        incurred.

    Revenue recognition:
        Revenue from research and development contracts is recognized in
        accordance with the terms of the respective contracts.  Revenue from
        certain contracts is recognized on a prorata basis over the life of the
        contract.  Related contract costs are generally incurred ratably over
        the contract term.  Revenue from achievement of milestone events  is
        recognized when all parties concur that the scientific results and/or
        milestones stipulated in the agreement have been met.  Revenue from
        time and materials contracts is recognized in the period in which the
        related services have been rendered and costs incurred by the Company.
        Revenue recognized in the accompanying consolidated statements of
        operations is not subject to repayment.  Revenue received that is
        related to future performance under such contracts is deferred and
        recognized as revenue when earned.

(1) Summary of Significant Accounting Policies, cont.

        Revenues from product sales are recognized upon shipment and passage of
        title to the customer.

    Concentration of credit risk:
        The Company's product sales are made primarily to distributors of
        agricultural products, located predominantly in North America.  The
        Company does not generally require collateral or other security to
        ensure collection of trade receivables, except for certain
        international sales, where letters of credit are obtained.

    Intangible and other assets:
        Intangible and other assets include purchased proprietary technology,
        patents, license fees and cost in excess of net assets acquired.
        Amounts capitalized are amortized over their estimated useful lives
        which range from 2.5 years to 15 years.  Technology acquired that is
        still in the research and development stage is charged to operations.
        Amortization expense on intangible assets amounted to $26,550, $135,631
        and $118,761 in fiscal 1996, 1995 and 1994, respectively.

    Cash and cash equivalents:
        For purposes of the consolidated statements of cash flows, the Company
        considers all highly liquid temporary investments purchased with an
        original maturity of three months or less to be cash equivalents.  Cash
        equivalents consist primarily of U.S. Government obligations,
        commercial paper and foreign money market accounts and are carried at
        cost which approximates market value.

    Temporary investments:
        Temporary investments consist of U.S. Government obligations and
        corporate debt securities with original maturities greater than three
        months.  The Company's temporary investments are available for sale to
        fund operations.

    Fair value of financial instruments:
        The fair value of the long-term debt approximates its carrying value
        due to its short-term maturity, and the interest rate approximates
        current market rates.  For all other financial instruments, their
        carrying value approximates fair value due to the short maturity of
        those instruments.

    Net loss per common share:
        Net loss per common share available to common stockholders, adjusted
        for preferred stock dividends of $116,700 in the year ended October 31,
        1996, is computed using the weighted average number of shares
        outstanding during the  period.  Common stock equivalents are not
        included in the computation of weighted average shares outstanding
        since the effect would be anti-dilutive for both primary and fully
        diluted earnings per share using the treasury stock method.

    Foreign currency translation:
        Substantially all assets and liabilities of the Company's foreign
        subsidiaries are translated at fiscal year-end exchange rates, while
        related income and expenses are translated at rates which approximate
        the exchange rates prevailing during the year.  The resulting
        adjustments are accumulated as a separate component of stockholders'
        equity.  Foreign currency transaction gains (losses) are charged to
        operations as incurred and amounted to ($20,245), ($16,940) and $33,452
        in fiscal 1996, 1995 and 1994, respectively.

(1) Summary of Significant Accounting Policies, cont.

    Income Taxes:
        The Company accounts for income taxes under Statement of Financial
        Accounting Standards No. 109 ("SFAS 109") "Accounting for Income
        Taxes."  Under the asset and liability method of SFAS 109, deferred tax
        assets and liabilities are recognized for the estimated future tax
        consequences attributable to differences between the financial
        statement carrying amounts of existing assets and liabilities and their
        respective tax bases and the benefits arising from the realization of
        operating loss  and tax credit carryforwards.  Deferred tax assets and
        liabilities are  measured using enacted tax rates in effect for the
        year in which those  temporary differences are expected to be recovered
        or settled.  A valuation allowance is provided when it is more likely
        than not that some portion or all of the deferred tax assets will not
        be realized.  Under SFAS 109, the effect on deferred tax assets and
        liabilities of a change in tax rates is recognized in income in the
        period that includes the enactment date of the tax rate change.

    Reclassification:
        Certain amounts contained in the 1995 and 1994 consolidated financial
        statements have been reclassified to conform to the 1996 presentation.

    Use of Estimates:
        The preparation of financial statements in conformity with generally
        accepted accounting principles requires management to make estimates
        and assumptions that affect the reported amounts of assets and
        liabilities and disclosure of contingent assets and liabilities at the
        date of the financial statements and the reported amounts of revenues
        and expenses during the reporting period.  Actual results could differ
        from those estimates.


(2) Investments

        Effective November 1, 1995, the Company adopted Statement of Financial
        Accounting Standards No. 115 ("SFAS 115"), "Accounting for Certain
        Investments in Debt and Equity Securities."  The effect of adopting
        this statement was not material.  Under this new accounting standard,
        securities for which there is not the positive intent and ability to
        hold to maturity are classified as available for sale and are carried
        at fair value.  Unrealized holding gains and losses on securities
        classified as available for sale are carried as a separate component of
        stockholders' equity.  The Company considers all of its current
        investments to be available for sale. Consequently, pursuant to SFAS
        115, a $9,742 unrealized holding gain has been recorded in a separate
        component of stockholders' equity as of October 31, 1996.

         from an Israeli Bank.  Principal payments of approximately $72,000 and
         $71,000 are due in 1999 and 2000, respectively.  The loan bears
         interest at 18%.

         working capital line of credit with a commercial bank.  At October 31,
         1996, the Company had not used the line of credit.  The line bears
         interest at the Company's option at either the bank's prime rate less
         1.25%, or LIBOR plus .5%, or the bank's certificate of deposit rate
         plus .75%.  Borrowings would be collateralized by the Company's
         investments. Under the loan agreement, the Company must maintain a
         consolidated tangible net worth of $5.0 million.  The loan agreement
         may be renewed annually for a two-year period.

         The Company has obtained a $2.0 million line of credit to be used
         for the leasing of production equipment.  The Company is required to
         pay interest only until the equipment is delivered, at which time the
         notes are converted to a capital lease obligation.  At October 31,
         1996, the Company had borrowed approximately $1.7 million, of which
         approximately $1.2 million has been converted to a capital lease

(8) Ecogen Technologies I Incorporated

         In 1992 Ecogen Technologies I Inc. ("ETech"), a corporation organized
         by but not affiliated with the Company, was formed to initiate or
         accelerate research and development of certain products using
         technology exclusively licensed or sublicensed by the Company to
         subsidiaries of ETech.  Pursuant to research and development agreements
         between Ecogen and each of the subsidiaries of ETech, Ecogen was
         conducting research, development and testing on the technology licensed
         to the subsidiaries of ETech in exchange for receiving reimbursement
         from ETech equal to Ecogen's development costs, as defined, plus a
         research management fee equal to 3.89% of such costs. Further, pursuant
         to a services agreement, ETech paid the Company a management fee equal
         to 5.75% of ETech's program subsidiaries' fully burdened costs. 
         Effective October 1, 1994, the Company discontinued recording contract
         revenue and management fees under the ETech agreements because it was
         the Company's intention to initiate an exchange offer for 20% or more
         of the ETech shares. During fiscal 1994, the Company earned contract
         revenue and management fees of $6,844,000 and $731,000, respectively.

(8) Ecogen Technologies I Incorporated, cont.

         During fiscal 1995, the Company acquired approximately 70% of the
         outstanding stock of ETech pursuant to an exchange offer. The Company
         issued 822,240 shares of its common stock having a market value of
         approximately $11.3 million.  At the date of the Exchange offer,
         investors were still obligated under ETech Investor notes issued in
         connection with the prior sale of equity securities by ETech.   The
         acquisition of approximately 70% of ETech was accounted for under the
         purchase method of accounting, and in fiscal 1995 the Company recorded
         approximately $9.1 million as a special charge to operations for the
         value of in-process research and development acquired from ETech. 
         Market feasibility and acceptance has not yet been established with
         respect to the ETech research programs and there is no assurance that
         the Company will be successful in its commercialization efforts.
         
         As a result of the acquisition, effective January 1, 1995, ETech's
         consolidated financial statements are consolidated with those of the
         Company, resulting in the Company recording 100% of the research and
         development expenses of ETech programs and reflecting any payments from
         ETech investors, subsequent to the Exchange Offer, as a long-term
         obligation. (See note 9 for unaudited pro forma information as a result
         of the acquisition.)  At October 31, 1995 approximately $1.6 million
         had been recorded as a long-term obligation for cash received from
         ETech investors not electing to exchange their ETech shares for the
         Company's shares.  The Company assumed the obligation to fund the final
         installment ($1.6 million) for those units participating in the
         exchange. During fiscal 1995, prior to the Company's acquisition of
         ETech, ETech collected from investors participating in the Exchange
         Offer and remitted to the Company approximately $3.0 million of
         payments under the ETech Investor Notes.

(9) Research, Development and License Agreements

         During 1991 and 1992, the Company, through Ecogen Europe S.r.l.
         ("Ecogen Europe"), a majority-owned subsidiary of Ecogen Inc., entered
         into two long-term research and development agreements with 3A S.r.l.
         ("3A"), an Italian corporation.  Ecogen Europe was owned 75% by the
         Company and 25% by 3A.  On October 23, 1995 the Company terminated its
         European research and development agreements with 3A. As part of the
         transaction, Ecogen transferred its ownership interest in Ecogen Europe
         to 3A and Ecogen Europe changed its name to Bio Integrated Technology
         S.r.l. ("BIT").
         
         As a result of the deal, Ecogen is released from the obligation to
         provide $5.6 million of funding to Ecogen Europe. Further, as part of
         the transaction, the Company received cash of approximately $1.0
         million and 683,202 of its common shares that had been held by Ecogen
         Europe.  The Company licensed to BIT the Company's existing nematode
         technology for use solely in Europe, Africa and the Middle East ("BIT
         Territory")  and agreed to provide BIT with improvements to certain of
         its nematode formulation technology.  BIT licensed to the Company
         nematode technology for use outside of BIT Territory.  The Company also
         licensed to BIT certain of its existing Bt technology, principally 12
         non-commercialized strains and process and formulation technology,
         solely for use in BIT Territory. The Company recorded a gain of
         approximately $.2 million on the transaction in fiscal 1995.  The
         Company will also pay BIT until the year 2002 a royalty on net sales in
         BIT's Territory of certain biofungicide products.

         The following unaudited pro forma results of operations for the years
         ended October 31, 1995 and 1994 give effect to the acquisition of 
         ETech and the disposition of the Company's interest in Ecogen Europe as
         though they had occurred on November 1, 1993.  The unaudited pro forma
         results include adjustments to eliminate Ecogen Europe's operations,
         including principally contract revenue, interest income and research
         and development expense, as if Ecogen Europe was not a consolidated
         subsidiary on November 1, 1993.  The unaudited pro forma results also
         include adjustments to eliminate contract revenue and management fees
         from ETech (see note 6) and to include all operating expenses of ETech
         as if ETech was a consolidated subsidiary on November 1, 1993.  The
         unaudited pro forma  results of operations do not include the 1995
         non-recurring gain of approximately $.2 million ($.04 per share)
         recorded on the Ecogen Europe transaction and $9.1 million for
         purchased technology for ETech.

         In connection with one of the 3A research agreements, the Company had a
         consulting agreement with a corporation whose president was a director
         of Ecogen Europe and a former director of the Company.  Under this
         agreement, the Company was obligated to issue 10,000 unregistered
         shares of common stock as a stock award.  The estimated fair value of
         this stock of $249,375 was recorded as a research agreement expense. 
         Such shares of common stock were issued in fiscal 1994. The Company
         also paid consulting fees to this individual aggregating $75,000 in
         fiscal 1994.  Further, in fiscal 1994 the Company paid 3A, $132,000 for
         management fees and facilities costs in Italy.
         
         Monsanto Transaction
         
         On January 24, 1996 the Company entered into an agreement with Monsanto
         Company (Monsanto) for an equity investment (see note 11), purchase of
         technology and joint research and development arrangement relating to
         the Company's proprietary Bacillus thuringiensis (Bt) technology for in
         plant applications (collectively, the "Monsanto Transaction").  The
         transaction includes the acquisition by Monsanto  of certain rights in
         the Company's Bt technology for an aggregate non-refundable purchase
         price of $5.0 million in cash which was recorded as other revenue in
         the first quarter of fiscal 1996, and a four year research and
         development collaboration arrangement with Monsanto for the further
         development of the Company's Bt gene library for a minimum of $10.0
         million, of which $3.0 million was paid in advance and recorded as
         deferred contract revenue during the first quarter of fiscal 1996. 
         During fiscal 1996, $1.9 million was earned under the terms of the
         agreement and recorded as contract revenue.

         During fiscal 1995, employees were given the right to exchange 290,079
         options at exercise prices from $32.30 to $65.88 for new options at an
         exercise price of $10.94, the fair market value at the grant date for
         the exchange right.  The new options are not  exercisable until the
         later of November 13, 1995 or the exercisable date of the option
         exchanged. Accordingly, options to purchase 290,079 shares were
         canceled and an equal number of new options were issued, which is
         reflected in the table above.

        The net change in the total valuation allowance for fiscal 1996 and
        1995 was an increase of approximately $900,000 and $7,701,000, 
        respectively. At October 31, 1996, the Company has net operating loss
        carryforwards for Federal income tax purposes of approximately $63.8
        million which are available to offset future Federal taxable income, if
        any, through 2011.  The Company also has research and experimentation
        tax credit carryforwards for Federal income tax purposes of
        approximately $2.4 million which are available to reduce future Federal
        income taxes, if any, through 2011.  The Company's ability to use such
        net operating loss and research and experimental credit carryforwards is
        subject to certain limitations due to ownership changes, as defined by
        rules enacted with the Tax Reform Act of 1986.
