ITEM 1.   BUSINESS

INTRODUCTION

     Enzo Biochem, Inc. (the "Company" or "Enzo") employing biotechnology,
develops, manufactures and markets health care products, and also provides
medical diagnostic services to the medical community.  Each of the three
business activities of the Company is performed by one of the Company's three
wholly-owned subsidiaries--Enzo Diagnostics, Inc., Enzo Therapeutics, Inc., and
Enzo Clinical Labs, Inc. ("Enzo Diagnostics", "Enzo Therapeutics" and "Enzo
Clinical Labs", respectively).  These activities are: (1) diagnostic and
research product development, manufacture and marketing through Enzo
Diagnostics, (2) therapeutic product research and development through Enzo
Therapeutics, and (3) the operation of a clinical reference laboratory through
Enzo Clinical Labs.  For information relating to the Company's business
segments, see Note 11 of the Notes to Consolidated Financial Statements.

     For the fiscal year ended July 31, 1996 (fiscal 1996), approximately 38%
of the Company's operating revenues was derived from product sales and
approximately 62% was derived from clinical reference laboratory services.  For
the fiscal years ended July 31, 1995 and 1994 (fiscal 1995 and fiscal 1994,
respectively), approximately 30% and 23%, respectively, of the Company's
operating revenues were derived from product sales and approximately 70% and
77%, respectively, were derived from clinical reference laboratory services.

PRODUCT DEVELOPMENT ACTIVITIES

     The Company's product development programs incorporate various scientific
areas of expertise, including recombinant DNA, monoclonal antibody development,
enzymology, microbiology, biochemistry, organic chemistry, and fermentation.
The Company's activities in research and development are performed by the
Company's professional and scientific staff.  To a lesser extent, research and
development is pursued in collaboration with outside consultants at research
and academic institutions.

     The primary focus of the Company's current research is the development of
products based on gene labeling and gene regulation. The Company is funding its
research programs through its operating cash flows and cash and cash
equivalents, as well as seeking joint ventures and collaborative relationships.

     Through Enzo Diagnostics, the Company has devoted a major portion of its
research and development activities to develop simple and reliable test formats
and protocols for the commercialization of nucleic acid-based diagnostics as
well as other diagnostic products.  A key system for Enzo is its non-
radioactive BIOPROBE-Registered Trademark- nucleic acid probe system and the
Company continued to introduce new products based on this technology into the
research market during fiscal 1996.

                                     3

<PAGE>


     The product development programs of the Company include developing 
BIOPROBE-Registered Trademark- nucleic acid probe products to detect sexually 
transmitted diseases, such as AIDS, herpes, chlamydia, gonorrhea, and other 
infectious diseases, such as tuberculosis, cytomegalovirus, hepatitis and 
Epstein-Barr virus (implicated in mononucleosis).  The Company markets 
several product lines containing BIOPROBE-Registered Trademark- nucleic acid 
probe products.

     The Company, through Enzo Therapeutics, is developing therapeutic
applications of nucleic acids.  In May 1987, the Company entered into an
agreement with the Research Foundation of the State University of New York
which grants the Company certain exclusive rights to a genetic engineering
technology for generating antisense RNA repressors.  As a result of the
technology covered by such agreement, the Company has obtained three (3)
patents.  Although the Company has not derived revenues from any of the
foregoing three antisense patents, the Company believes that this technology
will be the basis for the Company to derive meaningful revenues in the future.

     Whenever the Company complements its internal research and development
activities with collaborative research arrangements with academic and private
research institutions or consultants on specific projects, the Company
typically supplies funds to cover salaries, materials, certain laboratory
equipment and a portion of the overhead.  In all such collaborative research
arrangements, the Company reserves the commercial rights to any product or
process developed, subject to a royalty payment to the institution or
consultant involved over a period of years.  The location of the Company in the
greater New York area affords the Company access to and interaction with a
large number of research institutions and qualified scientists.

     In the fiscal years ended July 31, 1996, 1995 and 1994, the Company
incurred costs of approximately $3,083,000, $2,366,000 and $1,764,000,
respectively, for research and development activities.

CLINICAL REFERENCE LABORATORY

     The Company, through Enzo Clinical Labs, operates a clinical reference
laboratory which  offers full diagnostic services to the greater New York
medical community.  The services Enzo Clinical Labs provides include chemistry,
blood tests, cytology studies, tissue pathology, hormone studies, and
diagnostic procedures which seek to detect precancerous conditions, cancers in
cervical specimens and sexually transmitted diseases.  Enzo Clinical Labs
provides these services primarily to physicians as well as to clinics, nursing
homes and other clinical laboratories. Enzo Clinical Labs operates a regional
clinical reference laboratory on Long Island and also operates twelve satellite
patient service centers in the greater New York area, including a stat
laboratory in Manhattan. In addition, the Company utilizes its clinical
reference laboratory to evaluate and demonstrate the benefits of the Company's
diagnostic products (see Note 11 of the Notes to Consolidated Financial
Statements for segment information and operating revenues and profits).

                                     4

BUSINESS OBJECTIVES

     The current business objectives of the Company are (1) to develop,
manufacture and market on a worldwide basis diagnostic and therapeutic products
based on the Company's research activities in biotechnology and molecular
biology, and (2) to perform diagnostic tests for the U.S. health care
community.  The Company's research and development efforts are directed to both
short and long-term projects.  Diagnostic products require less time to
commercialize than therapeutic products because the procedures required for
attaining government clearance are less time consuming.  Therapeutic products,
once developed, require extensive clinical testing and compliance.  This
process can range from three to five years and, in some instances, longer.

     At such time as the Company's initial self-funded research demonstrates
technical feasibility and potential commercial importance, the Company will
have the option to pursue the opportunity on its own or to associate with
another entity for development and ultimate marketing of the product.  Unless
there is a business reason to license products or processes developed by the
Company, the Company intends to retain ownership with respect to development
and marketing of a product or process.

MARKETING STRATEGY

     Enzo's initial commercialization program for the BIOPROBE-Registered
Trademark- nucleic acid probe systems included filing major U.S. and foreign
patent applications, clinical evaluation, and Food and Drug Administration
(FDA) submissions.  The Company has obtained clearance for a number of FDA
approved diagnostics for sale to clinical reference laboratories and
researchers through Enzo Diagnostics. BIOPROBE-Registered Trademark- nucleic
acid probe products are also sold to the research market, where FDA clearance
is not required.  The Company has been successful in obtaining FDA clearance
for four totally Enzo-developed DNA probe products.  The Company believes that
significant delays will not be encountered with any future probe product
submissions to the FDA since products based on the BIOPROBE-Registered
Trademark- nucleic acid probe system have been FDA cleared.  However, there can
be no assurance that delays will not be incurred.

     Through Enzo Diagnostics, the Company manufactures and markets its
BIOPROBE-Registered Trademark- nucleic acid probe products for research
applications. These BIOPROBE-Registered Trademark- research products include
products which allow researchers to make their own non-radioactive DNA probes
as well as complete DNA probe kits which contain all reagents necessary for
detecting various disease pathogens in clinical samples.

     Enzo Diagnostics markets a variety of IN SITU hybridization kits.
PATHOGENE-Registered Trademark- DNA probe kits detect specific pathogens
including human papillomavirus (HPV), herpes simplex virus, cytomegalovirus,
Epstein-Barr virus, adenovirus, hepatitis B virus and CHLAMYDIA TRACHOMATIS.
Its BIOPAP-Registered Trademark- DNA probe kits detect certain types of HPV in
Pap smear samples. An enhanced detection procedure that will enable the
pathologist to identify the presence of fewer virus particles by increasing the
sensitivity of the assay was developed by the Company. These products compete
directly with products labeled

                                    5

<PAGE>

with various radioactive isotopes. In addition to the IN SITU hybridization 
kits, Enzo Diagnostics also markets kits based on its proprietary microplate 
hybridization format. Microplate Hybridization Assays have been developed for 
the detection of the AIDS-causing virus (HIV-1). Kits are also available to 
detect HIV-2, another strain of the AIDS virus, hepatitis virus, the bacteria 
causing tuberculosis (TB) and members of the MYCOBATERIUM TUBERCULOSIS (MTB) 
complex.

     Enzo's HIV test was one of the first commercial DNA probe tests for this
pathogen in this format.  Unlike most AIDS tests which detect antibodies for
HIV, Enzo's HIV Microplate Hybridization Assay detects DNA unique to HIV.
Since individuals can carry the HIV infection for up to 12 months before
developing antibodies to it, a test directed at the virus can provide earlier
detection.  Because this product also can measure virus concentrations, it is
easier for researchers to determine HIV levels in patients and look for
relationships between these levels and other disease indicators such as
antibody production or appearance of symptoms. This product is currently
marketed to the research community.     An enhanced version of the Microplate
Hybridization Assay, has been developed to detect the hepatitis virus directly
in serum and is aimed at the blood bank market.

     In early stages of infection, the pathogen may be present in very small
amounts and may be difficult to detect.  Samples, however, can be treated in a
way that produces copies of targeted DNA, if it is present.  This amplification
process is one possible approach to detect very low levels of infection.  All
of Enzo's Microplate Assays can be used to detect these pathogens in amplified
as well as unamplified samples.  In order to fully integrate its technology,
Enzo has developed a new simplified amplification process for multicopy
production of nucleic acid.  A patent application was filed in January 1994 and
this proprietary amplification process was incorporated into the microplate
assay format, thus providing a totally integrated assay system.  This approach
is being developed for use with the hepatitis assay system and will form the
basis for all Enzo's microplate assays.

     In addition to nucleic acid-based products, the Company also  produces and
sells other types of research products, such as monoclonal antibodies.  The
products are marketed through direct sales, an extensive product catalog,
advertising in scientific and trade journals and U.S. and foreign distributors.
In fiscal 1993, Enzo Diagnostics began to expand its non-exclusive distribution
arrangements for its proprietary products in both the U.S. and foreign markets
with various companies having worldwide distribution and with companies having
local foreign distribution.  In fiscal 1994, the Company continued to expand
these distribution arrangements and began a policy of using joint labels on all
products marketed by its distributors. In April, 1994, the Company signed a non-
exclusive worldwide distribution and supply agreement with Boehringer Mannheim
Biochemicals.  Under the terms of this agreement, Boehringer Mannheim
distributes to the global medical research market, a broad range of biochemical
products and reagents manufactured and supplied by Enzo.  The agreement
includes products based on nonradioactive DNA probe technology and includes
products that were developed and marketed by Boehringer Mannheim prior to the
agreement, as well as products developed

                                       6

<PAGE>

by the Company, all of which are covered by Enzo patents.  The agreement took 
effect in April 1994 and extends for the life of the last patent to expire 
for products involved.

     In February 1995, a distribution agreement was signed with Amersham 
International and includes a broad group of products developed and marketed 
by Amersham, as well as products developed by Enzo Diagnostics.  All products 
are based on nonradioactive DNA labeling technologies covered by Enzo 
patents.  A second agreement, also covering the Company's line of proprietary 
DNA labeling products and reagents  was concluded in May 1995 with Dako A/S, 
a privately-held international company with headquarters in Copenhagen, 
Denmark and subsidiaries worldwide, including the Dako Corporation based in 
Carpinteria, California.

     During fiscal 1996, a similar distribution agreement was concluded with
VWR Scientific Products, a leader in the medical research market that was
formerly an operating unit of Baxter Health Care.  Other agreements are
currently under discussion.

     The Company had previously entered into distribution agreements with
certain Johnson & Johnson, Inc. (J&J) subsidiaries in Europe, one of which
continues to be in effect.  Ortho Diagnostics continues to be the Company's
distributor for marketing, distribution and sale in Italy for the Company's
BIOPROBE-Registered Trademark- and other products.

     The Company, because of its various proprietary diagnostic technologies,
may enter into joint ventures with other biotechnology companies or other
health care companies with marketing resources and/or complementary technology
or products to more fully take advantage of market opportunities.

     Enzo Clinical Labs is a major regional clinical reference laboratory
offering full service diagnostic testing in the greater New York marketplace.
Its services are marketed by a professional sales force  who serve client
physicians, clinics, nursing homes and other clinical laboratories in the area.
A key marketing strategy has been the strategic placement of a network of
patient service centers, where patients can go to have samples taken upon the
request of their physicians.  The Company operates a stat laboratory at its
Manhattan patient service center, affording its client physicians rapid test
turnaround.  The diagnostic service business provides Enzo Diagnostics with a
practical application of its products, making it possible to more appropriately
tailor diagnostic products to the end-user.  The Company's BIOPROBE-Registered
Trademark- nucleic acid probe products offer Enzo Clinical Labs a marketing
tool by establishing it among the first to offer nucleic acid based tests.

TECHNOLOGY AND PRODUCT DEVELOPMENT

     The major focus of the Company's product development program has been
toward the commercialization of nucleic acid probe-based IN VITRO diagnostics
for specific pathogens.  Initially, nucleic acid probes were radioactive and
required complex protocols to perform.  To develop them into useful commercial
products required making such products easy-to-use, easy to interpret, readily
automatable and sensitive enough to detect the presence of low levels of
pathogen.  As a result of this product development effort, the Company has
developed a broad technology base for the labeling, detection,

                                  7

<PAGE>

sensitivity enhancement, signal amplification and testing formats of nucleic 
acid probe products.  Patent protection has been aggressively pursued for 
this technology base.  At the end of fiscal 1996 some 173 patents issued 
worldwide had been granted to or licensed by the Company in this area of 
technology. In fiscal 1995 and continuing during fiscal 1996, the Company 
began to receive significant revenues from the distribution agreements 
related to these patents and believes that the patents have positioned the 
Company to derive considerably more revenues in the future as the markets for 
these products continue to develop. These patents cover a variety of 
BIOPROBE-Registered Trademark- nucleic acid probe products, chelation 
technology for easy radioactive labeling, signal amplification methods, 
sensitivity enhancements, and automatable formats.

     BIOPROBE-Registered Trademark- Nucleic Acid Probe Labeling and Signal
                              Generating Systems

     Nucleic acid probes used traditionally in biomedical research and
recombinant DNA technology have been radioactively labeled with isotopes of
hydrogen, phosphorous, carbon or iodine.  Radioactive materials have
historically provided researchers with the most sensitive and, in many cases,
the only means to perform many important experimental or analytical tests.
However, limitations and drawbacks are associated with the use of radioactive
compounds.  For example, radioactive materials are often very unstable and have
a limited shelf-life.  Because of the potentially hazardous nature of
radioactive materials, their use must be licensed and elaborate safety
precautions must be maintained during the preparation, utilization and disposal
of radioisotopes.  In addition, radioactive nucleotides are extremely expensive
and their instability increases usage cost.

     To overcome the limitations of radioactively labeled probes, the Company,
starting with basic technology licensed from Yale University ("Yale"),  has
developed a proprietary technology which allows DNA probes to be used
effectively without the use of radioactivity.  This development permits the
application of genetic analysis in a clinical setting without the shelf-life,
licensing and disposal problems associated with radioactively labeled probes.

     In December 1987, a primary patent for the technology that is essential to
the development of nonradioactive DNA probe diagnostics was issued to Yale.  In
July 1994 and in September 1995 additional  patents, broadening the coverage of
the primary patent were also issued to Yale.  The Company has an exclusive
license for both patents from Yale for the life of the patents. Pursuant to
such license agreement, the Company is obligated to pay Yale royalties equal to
a percentage of sales. The Company is obligated to pay Yale an annual minimum
royalty fee of $200,000 which shall continue through the end of the term of the
exclusive license.

     The near term application of the BIOPROBE-Registered Trademark- nucleic
acid probe system in the human health care area is in bacterial and viral
diagnostics.  Nucleic acid probe diagnostics can be developed for any organism.
Advantages of the nucleic acid probes for the direct detection of pathogens in
human diagnostics are speed (less than an hour for test results as compared to
days), greater specificity, and the capability of diagnosing a disease in an
early or latent stage of development.

                         Radioactive Labeling Systems

     The Company has developed a new method for labeling molecules with
radioisotopes that is safer, faster, simpler and more cost effective than
traditional methods of radiolabeling.  This method is to be used in those
applications requiring more sensitivity than non-radioactive materials permit.
This method permits radiolabeling of a wide range of molecules for use in a
variety of applications, including IN VIVO imaging, therapeutics, and clinical
assays.

     With this technology stable products are radiolabeled just prior to use,
thereby overcoming inherent limitations of classical radiolabeling
technologies.  The Company's method for radiolabeling maximizes the sensitivity
while minimizing radiation exposure and radioactive waste.

     In November 1987, the Company received two U.S. patents protecting aspects
of its versatile technology for linking radioactive ions or biotin to various
biologically active molecules for diagnostic and therapeutic uses.  Since that
time  additional patents covering aspects of this technology have been issued
to the Company.

                           Automatable Test Formats
                                       
     In February 1991, the Company was granted a U.S. patent for its nucleic
acid probe testing technology that generates a signal in solution.  This
technology allows the development of nucleic acid probe-based tests that can be
readily automated and measured or identified instrumentally.  Using this
technology, probes can be detected with either chemiluminescent, fluorescent or
colorimetric methods.  The Company is developing test kits employing this
technology and launched two of them to the research market during fiscal 1992.
These included a test for the HIV virus which causes AIDS, and a test for the
bacteria causing tuberculosis.  In fiscal 1993 tests for other viruses,
including HIV-2, and hepatitis, were introduced to researchers. In fiscal 1994
a more sensitive assay that can detect hepatitis B virus directly in serum and
geared to the blood banking market was developed and in fiscal 1995 the
Company's amplification technology was integrated with the enhanced hepatitis
assay. The Company is developing an instrument-based automatable system
employing this and other proprietary Enzo technologies.
                                       
                          Rapid, On-Site Diagnostics
                                       
     The Company also has developed a diagnostic test technology which makes
possible accurate, rapid and one-step tests.  The ease of performing and
interpreting tests using this proprietary gel technology suits them well for at-
home and doctor office use.  Using the gel technology, the Company has
developed a fecal occult blood test used to screen for colorectal cancer.  The
Company has received FDA clearance to market this occult blood test to
physician offices and plans to develop other tests utilizing the gel technology
for aiding consumer health maintenance.

                             Monoclonal Antibodies

     The Company markets a panel of monoclonal antibodies that are being used
in pathology laboratories to help identify the original source of a metastatic
cancer and the type of cancer in undifferentiated cancer cells.  The ability to
identify the origin and type of cancer aids in the diagnosis of cancer and
assists physicians in prescribing therapy.  In order to offer a full line of
state-of-the-art research products, the Company is actively engaged in
expanding its line of monoclonal antibodies.

                Therapeutic Technology and Product Development

     Through Enzo Therapeutics, the Company is applying its technological
capabilities for manipulating genetic material towards the development of
therapeutic treatments for a variety of cancers and infections.  Enzo is
exploring applications of antisense nucleic acids employing various proprietary
technologies.  During fiscal 1996, the Company developed a new gene delivery
system that is designed to provide universal and efficient delivery of any gene
to any cell.  The GENSERT-TM- Universal Delivery System is being combined with
Enzo's antisense technology in its therapeutic development program.  Also, the
Company has developed techniques for stably attaching drugs and radioisotopes
to proteins and DNA.  The Company is working towards, INTER ALIA, the
development of products relating to HIV, certain cancers and hepatitis,
however, no products have been finalized.

     In May 1987, Enzo entered into an agreement with The Research Foundation
of the State of New York (SUNY) granting the Company certain exclusive rights
to a genetic antisense technology.  Because this antisense technology offers a
way to control the expression of any gene in any organism, the Company believes
it has broad therapeutic and agricultural applications. For example, this
technology should make possible a new approach to controlling viral diseases
and cancers in humans.  It may also be used to control viral diseases in
animals and agriculturally important plants and may lead to a variety of other
desirable traits in agricultural crops and animals.  This technology has been
proven to be effective in a variety of organisms, including plants, animals and
bacteria.  For example, researchers have developed transgenic mice that are
resistant to murine leukemia virus and tomato plants which produce tomatoes
that do not spoil upon ripening. However, to date the Company has not developed
any commercial products utilizing this technology.  Because this technology has
such broad application, the Company is exploring collaborative business
relationships of various types with other companies to develop the applications
which Enzo is not interested in retaining for its own activities. Three U.S.
patent applications were subsequently issued as patents by the U.S. Patent and
Trademark Office.  The first patent issued in March 1993; a second patent
issued in May 1993; the third patent issued in December 1993.

     In January 1995, the Company signed a collaborative research agreement
with Cornell University on behalf of its Medical College, aimed at evaluating
the Company's genetic antisense technology for use in managing the treatment of
HIV, the AIDS-causing virus.  Early research results indicated, that this
technology could be applied to inhibiting the function of genes necessary for
the HIV virus to grow within the cell.  In

                                       10

<PAGE>

preclinical studies currently underway, Enzo scientists and collaborators 
were able to demonstrate stable resistance to HIV in human immune cells in 
culture that were treated with the Company's HIV product.  In May 1996, the 
Company expanded the HIV development program and signed a second research 
agreement with St. Luke's-Roosevelt Hospital Center, aimed towards the 
development of protocols for its next phase of human clinical studies.

     In February 1996, the Company initiated a joint research program with
scientists at the Albert Einstein College of Medicine in New York City, geared
towards the development of a specific therapeutic product for the treatment of
hepatitis B based on the Company's novel gene regulation and delivery
technologies.

MANUFACTURING

     The Company's BIOPROBE-Registered Trademark- nucleic acid probe products
contained in its PATHOGENE-Registered Trademark- and BIOPAP-TM- product lines
are manufactured by using recombinant DNA techniques and traditional chemical
synthesis methods.  The DNA sequence which codes for a specific infectious
agent or particular trait is isolated by cloning.  The sequence is then
introduced into a plasmid, commonly one that grows in E.COLI bacteria, and the
bacteria serves as a reproduction vehicle with the application of standard
fermentation procedures.  The reproduced quantities of the specific DNA
sequences are purified from the bacteria and then labeled so they can be
detected.  The detection system usually employs a non-radioactive visualization
molecule, such as a color-changing enzyme-substrate or a fluorescent substance.
The production of DNA probes does not require large manufacturing facilities
because the yields from the bacteria are high and only small quantities of
nucleic acids are required.

     Monoclonal antibodies specific to certain substances are produced by
fusing a type of mouse cancer cell with certain antibody-producing white blood
cells from the spleens of mice that had been immunized with the targeted
substance.  The hybrid cells which make antibodies with the desired
characteristics are then cultured to produce large quantities of that one
discrete type of antibody.  Monoclonal antibody production does not require
extensive facilities.

     The Company's manufacturing operation uses exempt quantities of tritium
(3H) in its research and development activities and manufacturing operations.
For the fiscal year ended July 31, 1996 the Company has not had an accumulation
of tritium to be disposed.

REGULATION

     The Company's present and proposed activities are regulated by the federal
government to a significant extent.  This regulation applies not only to
research and development and manufacturing, but also to the marketing of
products, particularly those involving diagnostic or therapeutic applications.

     In order to test clinically, manufacture and market diagnostic or
therapeutic products, the Company (and/or its marketer) must obtain the
approval and comply with

                                  11

<PAGE>

the standards of the FDA in the United States and comparable agencies in 
other countries.  The FDA has established mandatory procedures and safety 
standards which apply to the clinical testing, manufacture and marketing of 
all diagnostic and therapeutic products.  FDA approval is not required for 
the sale of certain products for research use only.

     The process of seeking and obtaining FDA approval of a new therapeutic 
product generally takes a number of years and may require substantial 
funding. The process of seeking FDA clearance and corresponding foreign 
approvals is significantly less for IN VITRO diagnostic tests.

     The Company has in-house personnel to expedite the preparation and 
filing of documentation necessary for FDA clearances and approvals, patent 
issuances and licensing agreements.  The Company has received clearance from 
the FDA to market five of its diagnostic products. The Company also has 
several products in various stages of clinical trial evaluation which, if 
successful, are expected to be submitted to the FDA for clearance.

     The Company's clinical reference laboratories are subject to various 
federal, state and local licensing, permits and regulatory certifications.

     In addition to the foregoing, the Company's present and future business 
may be subject to regulation under the Occupational Safety and Health Act, 
Environmental Protection Act, Resource Conservation and Recovery Act and 
other present or possible future legislation, as well as by governmental 
agencies with regulatory authority relating to the Company's business.  From 
time to time, legislation has been introduced to regulate various aspects of 
the technology, but the Company is unaware of any proposed actions by 
federal, state or local authorities which might materially impair its ability 
to conduct its business.

PROPRIETARY TECHNOLOGY - PATENTS

     As novel techniques, processes, products or microorganisms are developed 
during the course of its research and development activities, the Company 
will seek U.S. and, if deemed necessary, foreign patents.  At the end of 
fiscal 1996 the Company owned or licensed 34 U.S. and some 151 foreign 
patents and had filed approximately 165 U.S. and foreign patent applications 
covering products, methods and procedures resulting from the Company's 
research projects.  In fiscal 1995 and continuing this fiscal year, the 
Company began to receive significant revenues from the distribution 
agreements related to these patents and believes that the patents have 
positioned the Company to derive considerably more revenues in the future as 
the markets for these products continue to develop. Patents relating to the 
BIOPROBE-Registered Trademark-nucleic acid probe system have issued in the 
U.S. and Europe.  Management believes that additional patents will issue 
shortly and over the next several years with respect to the Company's pending 
applications.  There can be no assurance, however, that patents will be 
issued on pending applications or that any issued patents will have 
commercial benefit.  The Company does not intend to rely on patent protection 
as the sole basis for protecting its proprietary technology.  It also relies 
on its

                                    12

<PAGE>

trade secrets and continuing technological innovation.  All employees 
involved in the clinical reference laboratory division and the manufacturing 
operations sign a confidentiality agreement prohibiting the employee from 
disclosing any confidential information about the Company, including the 
Company's technology or trade secrets.

     In some instances, the Company may enter into royalty agreements with
collaborating research parties in consideration for the commercial use by the
Company of the developments of their joint research.  In other instances a
patent may be obtained by the collaborating party with the Company receiving a
license to use the patented subject matter.  In such cases, the Company will
seek to secure exclusive licenses.

     In other instances, the Company may have an obligation to pay royalties
to, or reach a royalty arrangement with, a third party in consideration of the
Company's use of developments of such third party.  The Company has an
exclusive licensing agreement with Yale for the technology used in the BIOPROBE-
Registered Trademark- nucleic acid probe products.  The agreement covers
licensed patents owned by Yale and licensed to the Company for the life of the
patents which expire not earlier than 2004.

     In fiscal 1987, the Company entered into an agreement with The Research
Foundation of the State University of New York giving the Company exclusive
rights to a genetic engineering technology using antisense nucleic acid control
methodologies.  This technology is covered by three U.S. patents applications
subsequently issued as patents by the U.S. Patent and Trademark Office.  The
first patent issued in March 1993; a second patent issued in May 1993; the
third patent issued in December 1993. (See "Therapeutic Technology and Product
Development" section, page 10).  The term of the license agreement extends
through the life of such patents as may issue therefrom.

HUMAN RESOURCES

     As of July 31, 1996, the Company employed 176 full-time and 51 part-time
employees.  Of the full-time employees, 36 were engaged in research,
development, manufacturing and marketing of research products and 140 at the
clinical reference laboratories. The scientific staff of the Company possesses
a wide range of experience and expertise in the areas of recombinant DNA,
nucleic acid chemistry, molecular biology and immunology.  The Company believes
that relations with its employees are good.

COMPETITION

     The Company's biotechnology activities compete with pharmaceutical,
chemical, energy, and food companies which are diversifying into biotechnology,
and with specialized biotechnology firms in the United States and elsewhere.
Competition from existing companies and from newly formed private enterprises
is expected to increase.

     Most of the Company's competitors in the biotechnology industry are
performing research in many of the same areas as the Company.  Many of these
competitors are larger and have greater financial and other resources than the
Company. The primary competitive factors in the biotechnology field are the
ability to create and maintain

                                   13

<PAGE>

scientifically advanced technology during a period of rapid technological 
development, to attract and retain a breadth and depth of human resources, to 
develop proprietary products or processes and to have available adequate 
financial resources for bridging the often substantial time lag between 
technical concept and commercial implementation.

     The Company's clinical reference laboratories activity, which is conducted
in the New York metropolitan area, competes with numerous national and local
entities, some of which are larger and have greater financial resources than
the Company.  The laboratories compete based on the specialized nature of the
services performed, as well as on the reliability and speed in which they
perform the diagnostic tests.

</TABLE>

     On December 1, 1985, the Company entered into an Agreement with the City 
of New York to lease, over a fifty-year term, a six-story building located in 
New York City. In the fourth quarter of fiscal 1996, the Company negotiated a 
settlement with the City of New York to relieve the Company from any further 
obligations related to the lease and to return the building to the City and 
the Company agreed to pay the City $2,950,000 in full settlement of all of 
the City's claims for unpaid taxes and rent.  The Company issued to the City 
203,450 shares of the Company's common stock in August 1996 in consideration 
of the settlement amount.  If the City has not received the net proceeds of 
$2,950,000 upon the sale of such stock by March 17, 1997, the City shall 
return the remaining shares not sold, if any, and the Company shall pay the 
difference in cash.  As a result of this settlement with the City, the 
Company incurred a charge against earnings in the amount of approximately 
$7.6 million in the fourth quarter of fiscal 1996.

ITEM 3.  LEGAL PROCEEDINGS

     In March 1993, the Company filed suit in the United States District Court
for the District of Delaware charging patent infringement and acts of unfair
competition against Calgene, Inc. and seeking a declaratory judgment of
invalidity concerning Calgene's plant antisense patent.  On February 9,
1994, the Company filed a second suit in the United States District Court for
the District of Delaware charging Calgene with infringement of a second
antisense patent owned by the Company.  Calgene has filed a counterclaim in the
second Delaware action seeking a declaration that a third patent belonging to
the Company is invalid.  The two Delaware actions have been consolidated and
were tried to the Court in April 1995.  In addition, the Company filed suit on
March 22, 1994 in the United States District Court for the Western District of
Washington against Calgene and the Fred Hutchinson Cancer Research Center,
alleging that the defendants had conspired to issue a false and misleading
press release regarding a supposed "patent license" from Hutchinson to Calgene,
and conspired to damage the Company's antisense patents by improperly using
confidential information to challenge them in the Patent Office.  The Complaint
further charges that Hutchinson is infringing and inducing Calgene to infringe
the Company's antisense patents.  On February 2, 1996, the Delaware Court
issued an opinion ruling against Enzo and in favor of Calgene, finding certain
Enzo claims infringed, but the patent, as a whole not infringed, and finding
the claims at issue invalid for lack of enablement.  Calgene's patent was found
valid (non-obvious) over the prior art.  On February 29, 1996, the Delaware
Court issued an Order withdrawing its February 2, 1996 Opinion.  Enzo intends
to appeal from any adverse judgment.  There can be no assurance that the
Company will be successful in any of the foregoing matters or that Calgene
and/or Hutchinson will not be successful.  However, even if the Company is
not successful management does not believe there will be a significant monetary
impact.



ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were brought to a vote of the Company's stockholders in the

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

LIQUIDITY AND CAPITAL RESOURCES

     The Company, at July 31, 1996, had cash and cash equivalents of $17.8
million, an increase of $6.7 million from July 31, 1995.  The Company had net
working capital of $29.5 million at July 31, 1996 compared to $24.4 million at
July 31, 1995.

     The Company's income before taxes and before the writedown of leasehold 
interest and related costs was $105,000 which includes depreciation and 
amortization aggregating approximately $1.8 million.  The Company's positive 
cash flow from operations was sufficient to meet its current cash needs for 
the research and development programs and other investing activities.

     Net cash provided by operating activities was approximately $6.1 million 
and includes $5 million of cash received in connection with the litigation 
settlement.

     Net cash used by investing activities amounted to approximately $1 
million as a result of capital expenditures and deferred patent costs.  Net 
cash provided by financing activities of approximately $1.6 million primarily 
results from the proceeds from the exercise of stock options and warrants in 
fiscal 1996.

     On October 19, 1994 the Company executed a settlement agreement with 
Johnson & Johnson, Inc. (J&J) pursuant to which the Company received $15.0 
million and a promissory

                                         18

<PAGE>

note requiring J&J and its subsidiary, Ortho Diagnostics, Inc., to pay $5.0 
million a year for each of the four successive anniversaries of said date. 
These future payments are recorded at net present value discounted using an 
interest rate of 5.25%. The litigation settlement amounted to approximately 
$21.9 million, net of legal fees. Pursuant to the terms of the settlement, 
all of the Company's grants, licenses and intellectual property have been 
returned to the Company in totality.

     In December 1985, the Company entered into an agreement with the City of 
New York to lease, over a fifty year term, a building located in New York 
City. In the fourth quarter of fiscal 1996, the Company negotiated a 
settlement with the City of New York to relieve the Company from any further 
obligations related to the lease and to return the building to the City and 
the Company agreed to pay the City $2,950,000 in full settlement of all of 
the City's claims for unpaid taxes and rent.  The Company issued to the City 
203,450 shares of the Company's common stock in August 1996 in consideration 
of the settlement amount.  If the City has not received the net proceeds of 
$2.95 million upon the sale of such stock by March 17, 1997, the City shall 
return the remaining shares not sold, if any, and the Company shall pay the 
difference in cash.  As a result of this settlement with the City, the 
Company incurred a charge against earnings in the amount of approximately 
$7.6 million in the fourth quarter of fiscal 1996.

RESULTS OF OPERATIONS

     FISCAL 1996 COMPARED TO FISCAL 1995

     Revenues from operations for the fiscal year ended July 31, 1996 
("fiscal 1996") increased by $2,790,000 over revenues from operations for the 
fiscal year ended July 31, 1995 ("fiscal 1995").  This increase was due to an 
increase of $3,398,000 in revenues from research product sales over revenue 
for the similar activity in fiscal 1995 offset by a $608,000 decrease in 
revenues for the clinical reference laboratory operations.  The increase in 
research  product sales resulted primarily from the Company's non-exclusive 
distribution agreements for the Company's products.  The decrease in revenues 
from the clinical laboratory operations resulted primarily from a decrease in 
volume of unprofitable diagnostic screening tests.

     Cost of sales increased by approximately $1,563,000 as a result of the 
increase of $2,644,000 in the cost of sales of research products from the 
Company's distribution agreements activities offset by a decrease in the cost 
of clinical laboratory services of $1,081,000.  This decrease is primarily 
due from the improved efficiencies of performing certain diagnostic screening 
tests and the increase in the number of esoteric tests performed actually at 
the laboratory.

     Research and development expenses increased by approximately $717,000 as 
a result of an increase in research programs and the increased amortization 
of patent costs.

     The provision for uncollectable accounts receivable increased by 
$2,857,000 primarily due to an additional provision recorded by the Company, 
based on trends that

                                         19

<PAGE>

became evident in the fourth quarter, that additional reserves were needed 
primarily to cover lower collection rates under the Federal Medicare programs 
and other third-party insurance carriers.

     Selling and general and administrative expenses decreased by $2,463,000 
primarily due to a decrease in legal fees in fiscal 1996 and the overall 
improved efficiencies at the clinical reference laboratory.

     In the fourth quarter of fiscal 1996, the Company negotiated a 
settlement with the City of New York to relieve the Company from any further 
obligations related to the lease and to return the building to the City and 
the Company agreed to pay the City $2,950,000 in full settlement of all of the
City's claims for unpaid taxes and rent.  The Company issued to the City 
203,450 shares of the Company's common stock in August 1996 in consideration 
of the settlement amount. If the City has not received the net proceeds of 
$2.95 million upon the sale of such stock by March 17, 1997, the City shall 
return the remaining shares not sold, if any, and the Company shall pay the 
difference in cash.  As a result of this settlement with the City of New 
York, the Company incurred a charge against earnings in the amount of 
approximately $7.6 million in the fourth quarter of fiscal 1996.

     The operating profit from research and development activities and 
related costs amounts to $449,000 in fiscal 1996, as compared to an operating 
profit of $479,000 in fiscal 1995.  The decrease in the profit is principally 
related to the increase in research and development expenses from the 
diagnostic division.  The operating profit from the clinical reference 
laboratories activities amounted to $124,000 as compared to an operating 
profit of $2,146,000 in fiscal 1995.  This decrease resulted principally from 
the increase in the provision for uncollectable accounts receivable due to 
the lower collection rates under Medicare programs and other third-party 
insurance carriers and offsetting deduction in overall operating expenses.

RESULTS OF OPERATIONS

     FISCAL 1995 COMPARED TO FISCAL 1994

     Revenues from operations for the fiscal year ended July 31, 1995 
("fiscal 1995") increased by $8,901,000 over revenues from operations for the 
fiscal year ended July 31, 1994 ("fiscal 1994").  This increase was due to 
increases of $4,365,000 in revenues from research product sales over revenue 
for the similar activity in fiscal 1994 and by a $4,536,000 increase in 
revenues for the clinical reference laboratory operations.  The increase in 
revenues from the clinical laboratory operations resulted primarily from an 
increase in volume of screening tests. The increase in research product sales 
resulted primarily from the Company's non-exclusive distribution agreements 
to distribute the Company's products.

     Research and development expenses increased by approximately $602,000 as 
a result of an increase in research programs and the amortization of patent 
costs. Cost of sales increased by approximately $3,099,000 as a result of 
increased revenue from the sale of

                                      20

<PAGE>

research products and from the clinical reference laboratory.  This increase 
resulted primarily from the Company's non-exclusive distribution agreements 
to distribute products.  Included in the general and administrative expenses 
are legal fees of $2,977,000 and $1,663,000 for fiscal years 1995 and 1994, 
respectively.

     The provision for uncollectable accounts receivable increased by 
$341,000 primarily from an increase in operating revenues at the clinical 
reference laboratory operations. Selling expenses increased by approximately 
$701,000 due to an increase in marketing programs and personnel costs for the 
clinical reference laboratory operations.

     On October 19, 1994, the Company executed a settlement agreement with 
J&J pursuant to which the Company received $15.0 million in cash and a 
promissory note requiring J&J to pay a total of $5.0 million a year for each 
of the four successive anniversaries of said date.  These future payments are 
recorded at net present value discounted using an interest rate of 5.25%. The 
litigation settlement amounted to approximately $21,860,000, net of legal 
fees.

     The Company has recorded a writedown of the leasehold in the amount of 
$11,400,000 against earnings to its estimated fair market value in the fourth 
quarter of fiscal 1995 due to management's decision to seek alternative uses 
for the property.

     The operating profit from  the research and development activities and 
related costs amounted to $479,000 in fiscal 1995 as compared to an operating 
loss of $493,000 in fiscal 1994.  The increase in this profit is principally 
related to the Company's nonexclusive distribution agreements to distribute 
products.  The operating profit from the clinical reference laboratories 
activities amounted to a profit of $2,146,000 as compared to an operating 
loss of $659,000 in fiscal 1994. This increase resulted principally from an 
increase in the volume of screening tests.

     The provision for income taxes of $4,131,000 results from current income 
taxes due and utilization of net operating loss carryforwards related to 
taxable income recognized in connection with the J&J lawsuit.

     Net income for the fiscal year ended July 31, 1995 increased to 
approximately $5,618,000 compared with approximately $5,251,000 for the 
fiscal year ended July 31, 1994.

                        Report of Independent Auditors


Board of Directors and Stockholders
Enzo Biochem, Inc.

We have audited the accompanying consolidated balance sheets of Enzo Biochem, 
Inc. (the "Company") as of July 31, 1996 and 1995, and the related 
consolidated statements of operations, stockholders' equity, and cash flows 
for each of the three years in the period ended July 31,1996.  Our audits 
also included the financial statement schedule listed in the Index at Item 
14(a).  These financial statements and schedule are the responsibility of the 
Company's management.  Our responsibility is to express an opinion on these 
financial statements and 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 consolidated financial position
of Enzo Biochem, Inc. at July 31, 1996 and 1995 and the consolidated results
of their operations and their cash flows for each of the three years in the
period ended July 31, 1996, 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 herein.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                          July 31, 1996, 1995 and 1994


NOTE 1 - BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


BUSINESS

Enzo Biochem, Inc. (the "Company") is engaged in research, development, 
manufacturing and marketing of diagnostic and research products based on 
genetic engineering, biotechnology and molecular biology.  These diagnostic 
products will allow for the diagnosis of and/or screening for infectious 
diseases, cancers, genetic defects and other medically pertinent diagnostic 
information.  The Company operates a clinical reference laboratory which 
offers and provides diagnostic medical testing services to the health care 
community. The Company also is conducting research and development activities 
in the development of therapeutic products.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   PRINCIPLES OF CONSOLIDATION

The accompanying consolidated financial statements include the accounts of 
the Company and its wholly-owned subsidiaries.  All intercompany transactions 
and balances have been eliminated.

   CASH AND CASH EQUIVALENTS

The Company considers all highly liquid debt instruments purchased with 
maturities of three months or less to be cash equivalents.

Cash equivalents consist of short-term debt securities of the U.S. government 
that the Company intends to hold to maturity.  The market values of these 
securities, as determined by quoted sources, approximated cost at July 31, 
1996 and 1995.

   CONCENTRATION OF CREDIT RISK

Approximately 86% and 85% at July 31, 1996 and 1995, respectively, of the
Company's net accounts receivable relate to its clinical reference laboratory
business which operates in the New York Metropolitan area.  Concentration of
credit risk with respect to accounts receivable  are  limited  due  to  the
diversity  of the  Company's  client  base.  However, the

NOTE 1 - BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D)


   CONCENTRATION OF CREDIT RISK (CONT'D)

Company provides services to certain patients covered by various third-party
payors, including the Federal Medicare program.  Revenue, net of contractual
allowances, from direct billings under the Federal Medicare program during each
of the fiscal years ended July 31, 1996, 1995 and 1994 approximated 14%, 12%
and 17%, respectively of revenue.  The Company recorded an additional provision
for uncollectable accounts receivable of $3,500,000 based on trends that became
evident in the fourth quarter, that additional reserves were needed primarily
to cover lower collection rates under the Federal Medicare program and other
third-party payors.

At July 31, 1996 and 1995, 12% and 13% of the Company's net accounts receivable
relate to amounts due under non-exclusive world-wide distribution agreements
with Boehringer Mannheim and Amersham.  Operating revenues from Boehringer
Mannheim represented approximately 25% and 22% of consolidated operating
revenues in fiscal 1996 and 1995, respectively.

   INVENTORIES

Inventories are stated at the lower of cost (first-in, first-out method) or
market.

   PROPERTY AND EQUIPMENT

Equipment is being depreciated on the straight-line and accelerated methods
over the estimated useful lives of the assets.  Leasehold improvements are
amortized over the term of the related leases or estimated useful lives of the
assets, whichever is shorter.

   AMORTIZATION OF INTANGIBLE ASSETS

The cost in excess of fair value of net tangible assets acquired is being
amortized on the straight-line method over periods of twenty or forty years.

   PATENT COSTS

The Company has filed applications for United States and foreign patents
covering certain aspects of its technology.  The costs incurred in filing such
applications have been deferred and are amortized over the estimated useful
lives of the patents beginning upon issue.  Costs related to unsuccessful
patent applications are expensed.

NOTE 1 - BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONT'D)


   REVENUE RECOGNITION

Revenues from services from the clinical reference laboratory are recognized
when services are provided.  The Company's revenue is based on amounts billed
or billable for services rendered, net of contractual adjustments and other
arrangements made with third-party payors to provide services at less than
established billing rates. Revenues from research product sales are recognized
when the products are shipped.

   NET INCOME (LOSS) PER SHARE

Net income (loss) per share has been computed based upon the weighted average
number of common shares and dilutive common stock equivalents outstanding
during the year.  In fiscal 1996, common stock equivalents have not been
included because the effect of their inclusion would have been anti-dilutive.
The net income (loss) per share amounts for fiscal 1996, 1995 and 1994  have
been retroactively adjusted to reflect the 5% stock dividend declared in fiscal
1995 and for the 5% stock dividend declared in September 1996.  For 1994,
shares issuable upon conversion of the 9% convertible subordinated debentures
are not common stock equivalents, are antidilutive and, therefore, are also
excluded from the computation of net income (loss) per share.

   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 amount of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
amounts of income and expenses during the reporting period.  Actual results
could differ from those estimates.

   RECENTLY ISSUED ACCOUNTING STANDARDS

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".  This standard is effective for the Company's financial statements
beginning in the first quarter of fiscal 1997.  SFAS No. 121 establishes the
accounting for the impairment of long-lived assets, certain identifiable
intangibles and the excess of cost over net assets acquired, related to those
assets to be held and used in operations, whereby impairment losses are
required to be recorded when indicators of impairment are present and the
undiscounted cash flows estimated to be

   RECENTLY ISSUED ACCOUNTING STANDARDS (CONT'D)

generated by those assets are less than the assets carrying amount. SFAS No. 121
also addresses the accounting for long-lived assets and certain identifiable 
intangibles that are expected to be disposed of.  In the opinion of the 
Company's management, it is anticipated that the adoption of SFAS No. 121 
will not have a material effect on the consolidated results of operations or 
financial condition of the Company.

In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation," which requires adoption of the disclosure provisions in fiscal
1997.  The new standard defines a fair value method of accounting for the
issuance of stock options and other equity instruments.  Under the fair value
method, compensation cost is measured at the grant date based on the fair value
of the award and is recognized over the service period, which is usually the
vesting period.  Pursuant to SFAS No. 123, companies are encouraged, but are
not required, to adopt the fair value method of accounting for employee stock-
based transactions.  Companies are also permitted to continue to account for
such transactions under Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees," but would be required to disclose in a note to
the 1997 consolidated financial statements proforma net income and per share
amounts as if the Company had applied the new method of accounting.  SFAS No.
123 also requires increased disclosures for stock-based compensation
arrangements.  The Company has not yet determined if it will elect to change to
the fair value method or provide the necessary proforma information, nor has it
determined the effect the new standard will have on its operating and per share
results should it elect to make such change.

In the fourth quarter of fiscal 1996, the Company negotiated a settlement with
the City of New York to relieve the Company from any further obligations
related to the lease and to return the building to the City and the Company
agreed to pay the City $2,950,000 in full settlement of all of the City's
claims for unpaid taxes and rent.  The Company issued to the City 203,450
shares of the Company's common stock in August 1996 in consideration of the
settlement amount.  If the City has not received the net proceeds of $2,950,000
upon the sale of such stock by March 17, 1997, the City shall return the
remaining shares not sold, if any, and the Company shall pay the difference in
cash.  As a result of this settlement with the City, the Company incurred a
charge against earnings in the amount of approximately $7,613,000 in the fourth
quarter of fiscal 1996.

NOTE 7 - LITIGATION

 ORTHO DIAGNOSTIC SYSTEMS, INC.

On January 1, 1985, the Company entered into a follow-on agreement with Ortho
Diagnostic Systems, Inc. ("Ortho"), a subsidiary of Johnson and Johnson, Inc.
("J&J") pursuant to the 1982 agreement, whereby Ortho agreed to pay the Company
$11,000,000 over a four and one-half year period on a cost recovery basis in
support of research and development  projects. Ortho paid $4,500,000 to the
Company under this agreement up to January 1987 at which time Ortho indicated
its intention to suspend future scheduled payments under the agreements pending
resolution of certain matters. At July 31, 1994, the Company had a receivable
from Ortho of approximately $6,500,000.  Even though the Company continued to
perform its obligations under the agreements, it provided a total of $6,500,000
in prior years for the potentially uncollectable receivable from Ortho pending
resolution of the disputed items and the outcome of the civil suit filed by the
Company against Ortho and J&J.  This allowance for uncollectable receivable of
$6,500,000 was reversed in the fourth quarter of fiscal 1994 due to the
resolution of this matter, as discussed below.

The outside legal counsel was compensated on a contingency basis. During fiscal
1995, the Company issued approximately 110,000 shares  in exchange for $1.1
million in accrued legal fees.

On October 19, 1994, the Company executed a settlement agreement with J&J
pursuant to which the Company received $15.0 million in cash, of which $6.5
million related to amounts due under the agreements referred to above, and a
promissory note requiring J&J Ortho to pay a total of $5.0 million a year for
each of the four successive anniversaries of said date. Pursuant to the terms
of the settlement, all of the Company's grants, licenses and intellectual
property have been returned to the Company in totality.  These future payments
are recorded at their net present value of $14.1 million at July 31, 1996 in
the accompanying consolidated balance sheet, using a discount rate of 5.25%.


   CALGENE, INC.

   In March 1993, the Company filed suit in the United States District Court
for the District of Delaware charging patent infringement and acts of unfair
competition against Calgene, Inc. and seeking a declaratory judgment of
invalidity concerning Calgene, Inc.'s plant antisense patent. On February 9,
1994, the Company filed a second suit in the United States District Court for
the District of Delaware charging Calgene with infringement of a second
antisense patent owned by the Company.  Calgene filed a counterclaim in the
second Delaware action seeking a declaration that a third patent belonging to
the Company is invalid.  The two Delaware actions were consolidated and were
tried to the Court in April 1995. In addition, the Company filed suit on March
22, 1994 in the United States District Court for the Western District of
Washington against Calgene and the Fred Hutchinson Cancer Research Center,
alleging that the defendants had conspired to issue a false and misleading
press release regarding a supposed "patent license" from Hutchinson to Calgene,
and conspired to damage the Company's antisense patents by improperly using
confidential information to challenge them in the Patent Office.  The Complaint
further charges that Hutchinson is infringing and inducing Calgene to infringe
the Company's antisense patents.

   CALGENE, INC.(CONT'D)


On February 2, 1996, the Delaware Court issued an opinion ruling against Enzo
and in favor of Calgene, finding certain Enzo claims infringed, but the patent,
as a whole not infringed, and finding the claims at issue for lack of
enablement.  Calgene's patent was found valid (non-obvious) over the prior art.
On February 29, 1996, the Delaware Court issued an Order withdrawing its
February 2, 1996 Opinion.  Enzo intends to appeal from any adverse judgment.
There can be no assurance that the Company will be successful in any of the
foregoing matters or that Calgene, Inc. and/or Hutchinson will not be
successful.  However, even if the Company is not successful management does not
believe there will be a significant monetary impact.

NOTE 8 - INCOME TAXES (CONT'D)

Current income taxes provided for in fiscal 1996 relate primarily to state and
local taxes computed based upon capital.

Current income taxes of approximately $1,300,000 provided for in the fourth
quarter of fiscal 1995 are primarily calculated on the alternative minimum tax
method.

Deferred income taxes arise from temporary differences between the tax basis of
assets and liabilities and their reported amounts in the financial statements.
The components of deferred income taxes are as follows:

In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
asset will be realized.  The ultimate realization of the deferred tax asset is
dependent upon the generation of future taxable income.  Management considers
scheduled reversals of deferred tax liabilities, projected future taxable
income and tax planning strategies which can be implemented by the Company in
making this assessment.  The Company has provided a full  valuation  allowance
for  the  net  deferred tax asset at July 31, 1996 and 1995.  The

         WHEREAS, on or about November 18, 1985, the City, HHC as landlord,

                                      -2-

<PAGE>

         WHEREAS, the parties now desire to settle this proceeding and the 
Supreme Court Action and all disputes between them arising out of or relating 
to the Sublease and Amendment of Sublease and to finally and amicably resolve 
and settle any and all claims which have been pleaded in this proceeding and 
the Supreme Court Action or in any way related thereto as well as to provide 
for the termination of the Sublease and Amendment of Sublease without further 
liability of Enzo thereunder or in any way related thereto.

         NOW, THEREFORE, in consideration of the mutual promises of the 
parties hereto, the parties to this Stipulation and Order of Settlement 
("Stipulation") stipulate and agree as follows:

         1. The Non-Payment Proceeding is hereby settled with prejudice and 
without costs, disbursements or attorneys' fees to either side, upon the 
terms and conditions set forth in the Stipulation. 

         2. The Sublease and the Amendment of Sublease are hereby terminated 
in all respects so that none of the parties thereto shall have any other or 
further obligation or liabilities thereunder or by reason thereof, and Enzo 
shall be deemed to have vacated and surrendered the subject premises in its 
"as is" condition and the City and HHC shall be deemed to have accepted such 
vacatur and surrender simultaneously with the execution and delivery of the 
Stipulation.

         3. Upon the full execution and delivery of the Stipulation, HHC may 
take possession of and secure the subject premises without further notice to 
Enzo and Enzo shall

to the subject premises. 

         4. Any and all improvements, alterations, installations, and 
additions heretofore made by Enzo to or in the subject premises and currently 
located therein shall be deemed surrendered with the subject premises so that 
the same, upon the execution and delivery hereof, shall be the property of 
the City, without representation or warranty by Enzo of title or condition.  
Enzo shall and hereby does assign, set over and transfer to the City and HHC 
such rights, causes or claims it might have or hereafter have against any 
contractor or contractors employed by Enzo to perform work, labor or services 
at the subject premises, but Enzo does not represent or warrant that any such 
rights, causes or claims exist. 

         5. Simultaneously with the execution of this Stipulation, the 
parties shall execute a separate stipulation discontinuing the Non-Payment 
Proceeding with prejudice and without costs disbursements or attorneys' fees 
(the "Stipulation of Discontinuance").  The Stipulation of Discontinuance 
shall be held in escrow by the Office of the Corporation Counsel of the City 
of New York until the delivery by Enzo of the securities constituting the 
consideration for the settlement set forth in this Stipulation in the name of 
the City in accordance with paragraph 7 below, at which time the Stipulation 
of Discontinuance forthwith shall be filed with the court.  The Stipulation 
of Discontinuance shall be in the form annexed hereto as Exhibit A.


                                      -4-

<PAGE>

         6. Simultaneously with the execution of this Stipulation, the 
parties shall execute a separate stipulation discontinuing with prejudice and 
without costs disbursements or attorneys' fees the action brought by Enzo in 
Supreme Court, New York County, entitled ENZO BIOCHEM, INC. V. CITY OF NEW 
YORK, NEW YORK CITY HEALTH AND HOSPITALS CORP., Index No. 113887/95.  The 
stipulation described in this paragraph 6 shall be held in escrow by Anderson 
Kill & Olick, P.C., until the delivery by Enzo of the securities constituting 
the consideration for the settlement set forth in this Stipulation in the 
name of the City in accordance with paragraph 7 below, at which time said 
stipulation forthwith shall be filed with the court.  The proposed 
stipulation shall be in the form annexed hereto as Exhibit B.

         7. Enzo shall pay the City $2.95 million in full settlement of all 
of the City's and HHC's claims for rent,  additional rent, PILOT Payments or 
otherwise asserted against Enzo or arising under or by reason of the Sublease 
and Amendment of Sublease (the "Settlement Amount").  The Settlement Amount 
shall be paid in securities and or in cash in the form and manner and on the 
terms and conditions as set forth herein:

            (a) Within twenty (20) days of the execution of this Stipulation, 
Enzo shall issue, assign, transfer, convey and/or set over to the City and 
deliver to Citibank, N.A. as custodian for the City such number of shares of 
Enzo common stock ("Enzo Stock" or the "Stock") as shall have a market value 
if registered and freely transferable as of date of issue of at least $2.95 
million which value shall be computed using the 

                                      -5-

<PAGE>

closing price per share of the Stock on the American Stock Exchange on the 
day before the date of issue. 

            (b) Simultaneously with the issuance of the Stock Enzo shall 
deliver to the City (i) a duly executed resolution of Enzo's Board of 
Directors, certified by an appropriate officer of Enzo, approving the terms 
of the Stipulation and the issuance of the Stock; (ii) evidence of the 
transfer of the shares of Enzo Stock to the City on the books and records of 
the transfer agent and the registrar of the stock of Enzo.  The said 
documents shall be hand delivered to and received by Robin Green, Esq. or, if 
she is not available for any reason, Lawrence Kahn, Esq. each an Assistant 
Corporation Counsel, at the Office of the Corporation Counsel of the City of 
New York, 100 Church Street, Room 3-102, New York, New York  10007.

            (c) Simultaneously with the issuance of the Stock Enzo shall 
deposit with Anderson Kill & Olick, P.C. ("Escrow Agent") the sum of $2.95 
million (the "Escrow Fund") to secure the ultimate receipt by the City of the 
full Settlement Amount.  The Escrow Agent shall deposit the Escrow Fund in an 
interest bearing account at Citibank, N.A. or Chemical Bank in New York City. 

            (d) For a period of two hundred ten (210) days commencing with the 
issuance of the Stock, Enzo shall have the exclusive right and option to 
place or secure the sale of the Stock on behalf of the City in whole or in 
part which placement and sale or sales, if effected, may be to a transferee 
or transferees selected by Enzo in its discretion provided, however, 


                                      -6-

<PAGE>

that the City's consent to such transferee or transferees shall be required 
so long as such consent is not unreasonably withheld or delayed (the 
"Exclusive Sales Period").

            (e) The City (and, in turn, Citibank, N.A., its custodian), shall 
promptly facilitate the transfer or transfers of Stock at Enzo's request from 
time to time with the net proceeds of such transfer or transfers being paid 
to the City.

            (f) In the event Enzo shall not exercise its right and option to 
place or secure the sale of the Stock on behalf of the City within the 
Exclusive Sales Period or in the event all such Stock is not placed or sold 
within such period and the City has not received an aggregate net sum of 
$2.95 million from the portion of the Stock so sold, the City shall tender, 
offer and "put" the remaining Stock or such portion thereof as may not have 
been sold during the Exclusive Sales Period to Enzo and Enzo shall thereupon 
forthwith pay to the City the difference between $2.95 million and such 
amount or amounts as the City may have realized by sale or sales of the Stock 
during the Exclusive Sales Period, provided, however, that in the event Enzo 
does not purchase the Stock so tendered by the City for such amount the City 
may demand that Anderson Kill & Olick, P.C., as Escrow Agent, accept the 
stock tendered, offered and put to Enzo in which event Anderson Kill & Olick, 
P.C. shall forthwith pay to the City such amount out of the Escrow Fund as 
may equal the difference between $2.95 million and such amount or amounts as 
the City may have realized by sale or sales of the Stock during the Exclusive 
Sales Period.  The City shall be paid such 


                                      -7-

<PAGE>

aggregate sum of $2.95 million on or before March 19, 1997 net after the 
costs and expenses of sale including any and all sales commissions.  In no 
event is the City's entitlement hereunder to exceed $2.95 million.  In the 
event the City receives proceeds from the sale of any of the Stock or from 
the Escrow Agent aggregating $2.95 million, net after the costs and expenses 
of sale (including any and all commissions), the City or, as the case may be, 
the Escrow Agent, shall forthwith surrender any remaining Stock to Enzo for 
cancellation.  In such event the Escrow Agent may release the balance of the 
Escrow Fund and the interest accrued thereon, if any, to Enzo. 

         8. At such time as the City has received net proceeds equal to the 
Settlement Amount, Enzo shall have no further obligations pursuant to this 
Stipulation, and any Stock then remaining unsold shall be transferred to and 
re-registered to Enzo.  The City shall cooperate with Enzo in enforcing the 
terms of this paragraph, including, without limitation, executing a stock 
power or multiple stock powers and other documentation necessary to 
effectuate the registration, re-registration and/or transfer of the Stock, as 
provided herein.

         9. All notices to Enzo as required under this Stipulation shall be 
mailed by certified mail, return receipt requested to Enzo Biochem, Inc. at 
575 Fifth Avenue, New York, New York 10017 attention: Barry Weiner.  Failure 
or refusal of Enzo to accept the notice shall not affect the delivery of the 
notice under this Stipulation. 


                                      -8-

<PAGE>

         10. A copy of all notices to Enzo under this Stipulation shall also 
be sent by certified mail, return receipt requested, to Anderson Kill &

affect the delivery of the notice under this Stipulation. 

         12. This Stipulation and the executed counterparts of the Exhibits 
attached hereto and made a part hereof set forth the parties' entire 
understanding and agreement with respect to the subject matter hereof, and 
may not be modified, amended or waived other than pursuant to a writing 
signed by the parties hereto.

         13. This Stipulation shall bind and inure to the benefit of the 
parties hereto and their respective successors and assigns. 

         14. None of the terms contained in this Stipulation 
shall be deemed to constitute, or be based upon a policy of the 


                                      -9-

<PAGE>

City of New York.  This Stipulation shall not be admissible in, nor is it

         15. Each party hereto shall promptly do, execute, acknowledge, 
deliver, report, and file any and all further acts, certificates, assurances 
or other instruments as the other party may reasonably require from time to 
time in order to carry out more effectively the terms of this Stipulation. 

         16. (a) Enzo hereby waives and releases any and all claims, 
counterclaims and defenses it may have, including those which were raised or 
which could have been raised in this proceeding or in any action which could

<PAGE>

shall indemnify and save harmless the City and HHC from unknown and presently
