                                    PART I

ITEM 1. BUSINESS

General

         Neogen Corporation develops, manufactures, and markets a diverse
line of products dedicated to food and animal safety. The Company's products
are grouped into two areas, diagnostic test kits and veterinary instruments.
The Company's diagnostic test kits aid in the detection of foodborne
bacteria, natural toxins, drug residues, pesticide residues, plant disease
infections and quality aspects. These diagnostic test kits are generally less
expensive, easier to use and provide greater accuracy and speed than many of
the conventional diagnostic methods currently being used. The Company's
veterinary instrument product line assists in the promotion of animal health
principally through the delivery of more precise drug treatments such as
antibiotics and vaccines.

         The Company has developed and markets over 140 diagnostic test kits
used in food safety, animal safety, plant disease detection, pharmacologic
research and a limited number of products for human clinical use. These tests
are generally immunoassay products that rely on the Company's proprietary
antibodies capable of the detection of residues allowing for rapid and
accurate test results. All of the Company's diagnostic test kits are
disposable, single use products. The Company has developed its diagnostic
test kits so they can be utilized across multiple market segments.

         The diagnostic test kit segment also includes a line of consumable
products marketed primarily to veterinarians and distributors serving the
professional equine industry. These products include grooming aids, a
USDA-approved vaccine to prevent botulism in horses, a biologic used in
treatment of equine respiratory infections and a line of premium health care
products.

         The Company's Ideal Instruments subsidiary manufactures and markets
over 250 different veterinary instrument products used to administer animal
health and in obstetrics and surgery. The Company's veterinary instrument
product line assists in the promotion of animal health principally through
the delivery of more precise drug treatments such as antibiotics and
vaccines. The veterinary instrument line is aimed at reducing potential
residues in meat and milk while improving animal production efficiency.

         The Company's vision is to become a world leader in development and
marketing of products dedicated to food and animal safety. To meet this
vision, the Company has developed a growth strategy consisting of the
following elements: (i) increasing sales of existing products; (ii)
introducing new products and product lines; (iii) expanding international
sales; and (iv) acquiring business and forming strategic alliances.

         The Company was formed as a Michigan corporation in June 1981 and
actual operations began in 1982. The Company's principal executive offices
are located at 620 Lesher Place, Lansing, Michigan 48912-1595 and its
telephone number is (517) 372-9200.

Recent Developments

New Products

         In December, 1997, Neogen announced a qualitative histamine test for
the seafood market to be marketed under the name Alert(R) for Histamine. In
May, 1998, the Company announced the release of a quantitative histamine test
which is marketed under the name Veratox(R) Histamine. The Company estimates
the worldwide rapid histamine test market is $7 million.

         In October, 1997, Neogen introduced a new Alert test for the
detection of sulfites in seafood. The test was developed in cooperation with
the Aquatic Food Products Laboratory at the University of Florida. The test
is used by seafood processors to make certain sulfite levels do not exceed
federal regulatory levels.

         In July, 1997, the Company announced the release of the Reveal(R)
Bio-Plate test system. This diagnostic test system will be used within the
food industry to detect general E. coli. Testing for this bacteria is
mandated by new USDA/FSIS regulations. The total market for general E. coli
tests is estimated to be in excess of $10 million and is expected to grow a
rate of 20 percent per year.

         On June 25, 1997, the Company introduced a new diagnostic test kit
for the detection of Listeria. The Reveal(R) for Listeria Test System
utilizes the Oxoid(R) test device and Neogen's unitized enrichment media.
Listeria is a bacteria found in many different types of foods including meat,
eggs, dairy, chicken, seafood and vegetables. Management believes testing for
listeria will become growing and widespread.

                                     -2-

New U.S. Meat Regulations

         Federal regulations concerning food safety and food adulteration
have had a favorable impact on the sales of several of the Company's
diagnostic products. In July 1996, the U.S. Department of Agriculture's Food
Safety Inspection Service adopted a final rule governing federally inspected
meat and poultry processing plants, and businesses outside the U.S. which
export meat and poultry into the U.S. This rule and accompanying regulations
require mandatory testing for a number of hazardous adulterants that may
affect the safety of meat and poultry. Implementation of these regulations
have begun and will continue to be phased in over the next several years.
Management expects them to have a positive impact on sales of several of the
Company's diagnostic test kits.

 New U.S. Seafood Regulations Issued

         In December 1995, the U.S. Food and Drug Administration issued a
final rule concerning the procedures required for safe and sanitary
processing and importing of fish and fishery products. This rule and
accompanying regulations have had no material effect on the Company's
diagnostic revenues to this point, since the rule did not become effective
until January 1998. However, Company management believes these regulations
could have a positive impact on future sales for its seafood marketing group,
since the U.S. seafood industry has not previously been subject to mandatory
inspection.

Share Repurchase Program

         In August 1998, the Company announced that it would repurchase up to
250,000 shares of its outstanding common stock. The share repurchase program
was put in place because management and Neogen's Board of Directors believe
that the Company's shares are undervalued from time to time by the market.
The shares will be repurchased on the open market or in negotiated
transactions, depending upon market conditions and other factors.
Accordingly, there is no guarantee as to the exact number of shares to be
repurchased, if any.

Acquisitions

         A part of the Company's growth strategy has been to acquire products
and businesses that provide the Company with access to technology or products
with which to expand its core business. Since 1982, the Company has made
several such acquisitions. The information below summarizes recent
acquisitions.

  Triple Crown

         Effective July 1, 1997, the Company acquired substantially all of
the assets of Triple Crown, a division of W.J. Bartus, Inc. Neogen relocated
the business to its facilities in Lexington, Kentucky. The products and
technologies acquired have been merged into the Company's professional equine
division and added approximately $1,930,000 in new sales in the fiscal year
ended May 31, 1998. See Note 3 of the Notes to Consolidated Financial
Statements.

Vetoquinol U.S.A., Inc.

         Effective December 30, 1997, Neogen acquired substantially all of
the assets of Vetoquinol U.S.A., Inc. a wholly owned subsidiary of the French
company, Vetoquinol S.A. Sales and administrative functions have been moved
to the Company's Lexington, Kentucky facilities. Neogen continues to operate
a Tampa, Florida production facility. The principal product acquired is a
biologic used for the treatment of equine respiratory infections. The
acquired assets resulted in approximately $570,000 of sales during fiscal
year 1998. See Note 3 of the Notes to Consolidated Financial Statements.

Business Strategy

         The Company's vision is to become a worldwide leader in offering
products dedicated to food and animal safety. The Company expects to expand
its diagnostics and professional equine products, and increase its market
penetration of veterinary instruments with a focus on new delivery devices to
minimize animal trauma and reduce the likelihood of drug residues in meat and
milk products. The Company's strategy to achieve these objectives includes
the following:

                     * Increased Sales of Existing Products. The Company will
         continue to expand its product offering in multiple market segments
         including: grain, nut and spice processors; meat, poultry and egg
         processors; seafood processors; animal producers; fruit and
         vegetable producers/processors; food service providers; human
         clinical and pharmacologic research; and private and public
         laboratories. The Company has generally developed its diagnostic
         test kits so they can be utilized across multiple market segments.

                                     -3-

<PAGE>

                * Introduction of New Products. The Company has a continued
         commitment to research and development programs and has invested
         approximately 9% of revenues in this area over the past two years.
         The Company plans to continue to leverage its own internal research
         and development efforts through strategic relationships with other
         organizations and important government contracts and grants. The
         majority of the Company's new product development is focused on
         expanding disposable product offerings to the Company's current
         markets.

                    * Expansion of International Sales. The Company believes
         that the demand outside the United States for disposable diagnostic
         test kits such as those manufactured by the Company is at least
         equal to demand in the United States. As such, the Company will
         continue to emphasize international sales as an important factor in
         its growth. The Company is developing distribution channels to take
         advantage of these markets where there is a growing need for
         diagnostic test kits such as those manufactured by the Company.

                    * Acquisitions And Strategic Alliances. In the past, the
         Company has expanded its product offerings and technology base
         through several acquisitions. It also seeks to expand its products
         through licensing and distribution agreements. The Company plans to
         continue to aggressively pursue strategic acquisitions, and
         licensing and distribution agreements to enhance its position in its
         existing markets where it is more cost effective to use these
         strategies rather than to rely solely on internal development of new
         products.

Industry Overview

         Due to growing concern related to food and animal safety, animal
producers, food producers, processors, pharmaceutical and chemical companies,
research institutions, and regulatory agencies are all experiencing increased
pressures to find more efficient testing and monitoring programs. The
Company's strategy is based on its belief that there will be a continued
increase in demand for effective tools to better manage the use of biological
products and to detect harmful residues and microorganisms when present in
food, animal feeds, and the environment. Similarly, management believes that
demand for products to ensure safety in food and companion animals will
continue to grow.

         Industry consulting groups have estimated the total market for
testing of food and environmental safety will be in the range of $500 million
within the next several years. They estimate that a significant portion of
this potential market is represented by firms not testing and tests that are
not currently being conducted. Another significant portion of the market is
represented by older, traditional methods utilizing laborious microbiological
techniques, or time consuming, and expensive, chemical analysis. Management
believes that a significant portion of this market potential will shift to
rapid, easy to use and inexpensive, test systems such as those produced by
the Company.

Company Markets

         The Company has focused its strategy on the food safety and animal
safety markets. The Company is marketing and developing several types of
diagnostic tests to aid each of the individual food market areas in detecting
natural toxins, drug residues, foodborne bacteria, pesticide residues,
disease infections and quality aspects. The Company's products are sold into
definable market segments:

         Grain, nut and spice processors. Corn, wheat, barley, oats, milo,
rice, oil seeds and various other minor grain products become the principal
ingredient for a multitude of food industries. A large variety of nuts, along
with spices, chocolate, coffee and tea, are also universally consumed. The
safety of these ingredients is a significant source of concern for snack food
producers, pasta manufacturers, flour millers, animal feed processors,
bakeries, baby food producers, brewers, distillers and cereal manufacturers,
just to name a few of those whose livelihood depends upon the abundance of
safe ingredients.

         The Company's diagnostic tests are used throughout these industries
to monitor for the presence of harmful natural toxins, pesticides and
foodborne bacteria. The Company generally defines this market as being from
the time the products leave the farm gate until they reach the consumer's
plate.

         Management believes it is the leader in the sale of disposable
diagnostic tests to the grain, nut and spice industries and has a larger
selection of products available to these industries than any of its
competitors.

         Meat, Poultry and Egg Processors. According to the U.S. Department
of Agriculture, there are approximately 114 million cattle, hogs and lambs
slaughtered in the U.S. each year and over 840 million chickens are processed
in the U.S. annually. The principal concern for meat, poultry and egg safety
is contamination by foodborne bacteria.

                                     -4-

         Management believes that the meat and poultry group offers one of
the best opportunities currently to contribute to the Company's growth. The
Company offers tests for the bacteria E. coli O157:H7 and general E. coli,
salmonella, listeria, and several tests to determine the general level of
plant sanitation.

         A major reorganization in testing procedures by the U.S. Department
of Agriculture's Food Safety Inspection Service was announced in July 1996.
Implementation of these new regulations began in January 1997 for all meat
and poultry plants in the U.S. according to an adoption schedule that will
continue through January 2000. These new regulations will mandate certain
bacteria testing by all inspected plants, and the programs will encourage the
use of a number of other rapid tests, such as those produced by the Company.

         Seafood Processors. Seafood is known to cause foodborne illnesses as
a result of both natural toxins and bacteria. In December 1995, the U.S. Food
and Drug Administration issued final rules that established mandatory
inspection programs for the seafood industry in the U.S. effective January,
1998. The industry is now beginning to implement quality control procedures
that will include the use of rapid diagnostic tests. The Company's tests for
this market include a general sanitation rapid test as well as tests used to
detect the presence of salmonella, listeria, sulfites and histamine, which
can result in serious illness or death.

         A significant portion of the world's seafood supply now comes from
aquaculture production rather than wild harvest. These producers and
processors must also be concerned about the possibilities of pesticide
contamination from runoff water into their production areas and residues of
drugs that may have been used to ensure fish health during the production
process.

         Animal Producers. The animal production industry promotes food
safety even while the animal is inside the farm gate. The Company's Ideal
Instruments subsidiary manufacturers and markets 250 different products that
are used to administer animal health. Developed to provide more precise drug
delivery, these instruments help minimize the presence of animal health drugs
that might find their way into the meat and milk supply.

         The Company also markets a vaccine, immunostimulant, specialized
testing service, and a line of premium healthcare products that are sold to
the professional equine market. The Company's line of diagnostic tests to
detect drugs in animals are sold virtually throughout the world to detect the
presence of drugs of abuse in racing animals. Most racing jurisdictions
perform post-race tests on horses and greyhounds to make certain the animals'
performance was not altered intentionally by some drug.

         Many integrated poultry and livestock producers also use the
Company's diagnostic tests to detect harmful residues in animal feeds. These
residues can affect overall production efficiencies.

         Fruit and Vegetable Producers/Processors. As with animals,
significant portions of food safety begin inside the farm gate where plant
production takes place. The Company manufactures and markets a group of
diagnostic tests that are used by fruit and vegetable producers as well as
greenhouse and ornamental plant producers to detect the presence of certain
infectious diseases. These diseases affect crop production and can play a
major role in the quality and safety of the final food products.

         This industry's testing arises from the potential presence of
harmful residues that might affect the safety of its products. The residues
that require rapid and inexpensive test kits include foodborne bacteria,
natural toxins, and pesticides. Several of the Company's products meet these
industry needs and others are being developed.

         Human Clinical and Pharmacologic Research. The Company sells a
limited number of products used in clinical medicine and by the
pharmaceutical research industry. Since these products can be manufactured in
the same facilities, utilizing the same equipment and personnel, the Company
has continued to support this market activity.

         As the Company continues to develop diagnostic tests for the
detection of foodborne bacteria, it foresees an opportunity to introduce
these products into the human clinical market. For example, the same test
used to detect the presence of salmonella in a food product can also be used
clinically to determine if a patient is suffering from salmonella infection.
The market for human clinical test products is well-established and is served
by a number of mature, well-capitalized firms. As a result, the Company does
not intend to enter into this market by itself, but expects to pursue
opportunities in this market only by means of strategic alliances and joint
ventures with companies presently in the market.

         As a part of its immunoassay diagnostics test development programs,
the Company has discovered methods to manufacture unique, stable enzymes used
in test color development. The Company now markets these products to research
laboratories and other commercial diagnostic kit manufacturers around the
world.

         The Company does not anticipate being a major factor in these
markets. However, its current products are profitable and synergistic to the
Company's other manufacturing activities.

                                     -5-

         Private and Public Laboratories. Private laboratories purchase
diagnostic tests from the Company to provide testing services to most of the
market areas indicated in this section. These private laboratories perform
tests for firms which do not wish to do their own testing internally. Public
laboratories generally use the Company's test for regulatory purposes. As an
example, the U.S. Department of Agriculture uses several of the Company's
natural toxin test kits to determine the quality and safety of grain
products. The Company's test kit for the detection of E. coli O157:H7 is used
by the Food Safety Inspection Service to monitor for the presence of this
harmful bacteria in a number of laboratory locations. The Company's bacteria
tests are used by government animal pathology labs to aid in determining
causes of animal health problems, and plant tests are used in regulatory labs
to aid in plant quarantine situations.

Products

Diagnostic Test Kits

         The Company has developed and markets over 140 separate diagnostic
test kits used in food safety, animal safety, plant diseases, pharmacologic
research and a limited number of products for human clinical use. These tests
are generally characterized as immunoassay products that rely on the
Company's proprietary antibodies capable of detecting specific analyses at
the parts per billion levels. Generally, the test kits are single use,
faster, less expensive, require less laboratory equipment and less technical
capabilities than conventional testing methods.

         Food Safety. Several of the Company's food safety test kits are
aimed at the detection of harmful foodborne bacteria. These tests are
marketed under the Company's tradename, Reveal(R). Current tests in this
one-step simple format are used to detect the presence of salmonella,
listeria, general E. coli and E. coli O157:H7. Neogen also markets a test for
general E. Coli under the Reveal name and company scientists are developing
test kits for other harmful bacteria. Through a marketing agreement with
Merck KGaA, the Company has the distribution rights to the U.S. food industry
for HY-LITE(R), which is used to detect general plant sanitation levels. The
Company also has marketing rights from Orion Diagnostica to distribute four
different tests for microbiological contamination including yeast and fungi.

         The Company's Veratox(R) Agri-Screen(R) diagnostic tests are used by
the food industry to detect levels of naturally occurring toxins. These
products include both qualitative and quantitative tests for aflatoxin,
vomitoxin, T-2 toxin, zeralenone, ochratoxin, histamine and fumonisin. Other
natural toxin tests are being developed to detect toxins of concern in fruits
and vegetables.

         The Company's Agri-Screen Ticket(R) test is used by the food
industry to detect harmful residues of a large number of plant pesticides.
The seafood industry uses the Company's Alert for Sulfites to make certain
sulfilte levels do not exceed federal regulatory levels.

         Animal Safety. The Company markets over 50 high sensitivity
immunoassay tests for drugs of abuse in animals and residues in meat. These
include tests for narcotic analgesics, stimulants, depressants,
tranquilizers, anesthetics, steroids and diuretics. Neogen also provides a
testing service for equine veterinarians to detect EPM which affects the
central nervous system of horses and can be fatal. In addition, the company
markets Bot Tox B, the only USDA approved vaccine for the prevention of Type
B botulism in horses and a line of approximately 20 premium health care
products sold to the professional equine market. Neogen also markets
EqStim(R), and Immuno Regulin(R), biologic products used as immunostimulants
to help fight off infections in horses and dogs.

         The Company also has developed a test kit for the detection of a
proprietary drug used to control internal parasites. This test kit allows
poultry producers to monitor for the effective level of this drug as a feed
additive. The Company's tests for bacteria and natural toxins are also used
by producers to ensure animal health.

         Plant Diseases. Marketed under the tradename Alert(R), the Company
has several diagnostic tests that are used to detect plant diseases. These
quick tests identify the presence of Pythium, Phytophthora, Rhizoctonia,
Xanthamonas, and Sclerotina. The kits are used as an early detection device,
and as a tool to limit fungicide applications.

         Other Diagnostic Tests. Marketed under the AMPCOR(R) label, the
Company has 15 different diagnostic tests used by the human clinical market
for the detection of serology disorders and a sexually transmitted disease.

         The Company also has several products used for the detection of
biologically active substances in humans by researchers and pharmaceutical
companies for biomedical research purposes. These tests are used to detect
cyclic nucleotides, hormones, leukotrienes, prostaglandins and steroids.
Under the trademarks K-Blue and -Gold, the Company sells reagents used by
others in diagnostic test kit manufacturing.

         Sales of diagnostic products accounted for approximately 81% and 78%
of the Company's total revenues for fiscal years 1998 and 1997, respectively.

                                     -6-

  Veterinary Instruments

         Through its wholly-owned subsidiary Ideal Instruments, Inc.
("Ideal"), the Company markets a complete line of veterinary instruments and
animal health delivery systems. Ideal offers approximately 250 different
products, over half of which are instruments used to deliver animal health
products such as antibiotics and vaccines. Most of the remaining instruments
are used in obstetrics and surgery. Included among these products is a line
of disposable syringes and needles presently custom manufactured and imported
by Ideal.

         The veterinary instruments product line is designed to provide
better control of animal health products, thereby reducing the likelihood of
antibiotic and pharmaceutical residues contaminating meat or milk products.
At the same time, the use of quality, high precision delivery instruments
helps producers improve efficiency.

         In fiscal years ended May 31, 1998 and 1997, sales of veterinary
instruments as a percentage of total revenues were 19% and 22% respectively.

Research and Development

         The Company maintains a strong commitment to research and
development. The Company's product development efforts are focused on the
enhancement of existing product lines and in development of new products
based on the Company's existing technologies. The Company employs 27
individuals in its research and development department, including
immunologists, chemists, engineers and microbiologists. Research and
development expenditures were approximately $1.4 million and $1.3 million,
representing 8% and 9%, of total revenues in fiscal 1998 and 1997,
respectively. The Company currently intends to maintain its research and
development expenditures at approximately 9% of total revenues.

         The Company has ongoing development projects for new immunoassay
diagnostic tests for the food safety, animal safety and pharamacologics
markets, as well as engineering projects for new and improved veterinary
instruments.

         Collaboration with Academic Institutions. Since its inception, the
Company has identified a substantial amount of applied research in its area
of interest at universities that has been developed by researchers. The
Company has worked with over 45 scientific collaborators associated with 17
academic institutions. The Company utilizes these relationships in three
strategic ways: (i) the technology is transferred from the scientist or
university to the Company for the completion of development from the
precursor findings or laboratory prototypes; (ii) the Company seeks out and
contracts with university researchers to aid its own staff in a part of the
development activities for products previously identified by the Company; and
(iii) new products developed by the Company are tested in laboratories on a
widespread geographic basis prior to the products' market release. The
Company believes in research strategy has enabled it to produce better
products, faster and more cost effectively than if the research, development
and testing were done exclusively by Company employees in Company facilities.

         Other Collaboration Efforts. Portions of certain technologies
utilized in some products marketed by the Company were acquired from or
developed in collaboration with affiliated partnerships, independent
scientists, governmental units, universities, and other third parties. The
Company has entered into agreements with these parties which provide for the
payment of royalties based upon sales of products which utilize the pertinent
technology. For fiscal 1998 and 1997, royalty payments under these agreements
amounted to $ 713,000, and $771,000, respectively.

Sales and Marketing

         The Company has chosen to organize its sales efforts according to
market segments rather than by product or geographic orientation. The
Company's sales and technical service organizations understand their
customers' businesses and are knowledgeable on how the Company's various
products can be used within those industries. Close relationships built with
individual customers also help the Company identify new diagnostic test
products that can be useful.

         During the fiscal year ended May 31, 1998, the Company had in excess
of 2,000 customers for its products. Since many of these customers are
distributors, the total number of end users of the Company's products is
considerably larger. Sales to international markets in 

                                     -7-

<PAGE>
fiscal 1998 accounted for 22% of the Company's consolidated revenues. See
Note 10 of the Notes to the Company's Consolidated Financial Statements. No
single distributor or customer accounted for more than 10% of the Company's
revenues in any of the past three years.

         The Company markets, sells and services its products in more than 75
countries through its own sales force, as well as through distributors in
certain geographic areas. 63 people, or approximately 30% of the Company's
total employees, are engaged in these sales and marketing activities. The
Company operates its sales and distribution organization differently for
given markets and products as summarized below:

         Food Safety Products. The Company has separately organized sales
forces that focus on the key industries in the food area. This group handles
both sales and technical services of the Company's disposable test kits. In
the U.S. these products are sold directly to end-users. Sales Organizations
are maintained for: grain, nut and spices; meat, poultry and eggs; fruits and
vegetables; retail food services; private laboratories; and seafood.

         Animal Safety/Veterinary Instruments. The Company maintains
separately organized sales forces that focus on the professional equine
market and veterinary instruments. Products for the professional equine
market are handled by a direct sales force who sell directly to equine
veterinarians and also work through established distributors selling to this
market. The Company markets virtually all of its veterinary instruments
through a network of domestic and international distributors. These
distributors typically market pharmaceutical and biological products that are
companions to veterinary instruments. The Company has a sales force
specifically dedicated to sales of veterinary instruments through the
distributor channels.

         Clinical and Pharmacologic Biomedical Research. The Company does not
anticipate being a major factor in the marketing of products used in the
human clinical and pharmaceutical research areas. However, several products
are included in the Company's array of diagnostic tests as a result of
acquisitions. These products are profitable and synergistic to the Company's
other manufacturing activities. A separate sales organization is responsible
for this product group and sells through distributors and to large end users.

         International Sales. Virtually all of the Company's sales to
customers outside of the U.S. and Canada are through distributors who
typically market the Company's products as well as other products that are
used by the same customer base. The Company's distribution organization is
stronger in the South and Central American countries than in Europe or Asia
since this geographic area was the Company's first focus. The Company is
currently pursuing distribution channels in Europe and Asia to increase
sales. The Company does not maintain sales offices outside the U.S.

Proprietary Protection And Approvals

         The Company applies for patents and trademarks whenever appropriate.
Since its inception, the Company has acquired and received more than 50
patents and trademarks, and has several pending patents and trademarks. The
patents expire at various times over the next 20 years.

         Management believes that the Company has adequate protection as to
proprietary rights for its products. However, the Company is aware that
substantial research in agricultural biotechnology has taken place at
universities, governmental agencies and other companies throughout the world
and that numerous patent applications have been filed and that and that
numerous patents have been issued. In addition, patent litigation currently
exists with respect to fundamental agricultural biotechnology and
biochemistry. Accordingly, there can be no assurance that the Company's
existing patents will be sufficient to protect completely the Company's
proprietary rights.

         The Company uses trade secrets as proprietary protection in numerous
of its diagnostic products. In many cases, the Company has developed unique
antibodies capable of detecting residues in minute levels. The supply of
these antibodies, and the proprietary techniques utilized for their
development, oftentimes offer better protection than the filing of patents.
Such proprietary reagents are kept in secure facilities and stored in more
than one location to circumvent their destruction by natural disaster.

         One of the major areas affecting the success of biotechnology
development involves the time, costs and uncertainty surrounding regulatory
approvals. Currently, the Company has several products requiring regulatory
approval including Bot Tox-B(R), EqStim(R), Immuno Regulin(R) and serological
test kits sold to human clinical laboratories. On a combined bases, sales for
these products amounted to approximately 10% of total sales in fiscal year
1998. The Company's strategy is to select technical and proprietary products
which do not require mandatory approval to be marketed.

         The Company does utilize third party validations on many of its
disposable test kits as a marketing tool to provide its customers with the
proper assurances. These include validation by the Association of Official
Analytical Chemists, independently administered third-party, multi-laboratory
collaborative studies and approvals by the U.S. Federal Grain Inspection
Service and the U.S. Food Safety Inspection Service for use of Company
products in their own laboratories.

                                     -8-

Manufacturing

         The Company manufactures its products in Lansing, Michigan,
Lexington, Kentucky, Bridgeport, New Jersey, Schiller Park, Illinois and
Tampa, Florida. There are currently 90 full-time employees assigned to
manufacturing in these five locations. All locations generally operate on a
one-shift basis, but could be increased to a two-shift basis. The Company
believes it could double its current output of its primary product lines
using the current space available with minimal amounts of additional capital
equipment.

         The Company's Schiller Park, Illinois facility, which is used
primarily to manufacture the Ideal veterinary instruments line, is a complete
metal working operation with equipment that allows Ideal to go from raw
materials, such as brass rod and tubing, to finished instruments with
skin-wrapped merchandisable packaging.

         The Lexington, Kentucky facility is devoted exclusively to the
manufacture of pharmacological diagnostic test kits, test kits for drug
residues and professional equine products. Proprietary antibodies for some of
these diagnostic kits were produced at the University of Kentucky under a
license and supply agreement. All other manufacturing operations, including
preparation of other reagents, quality assurance and final kit assembly, are
performed by Neogen personnel in the Lexington facilities.

         The Tampa, Florida facility is a USDA approved manufacturing plant
devoted to the production of the biologic products EqStim and Immuno Regulin.
P. acnes seed cultures are added to media and then subjected to several
stages of further processing resulting in a product that is filled and
packaged within the Tampa facility. Final product is then shipped to Neogen's
Lexington, Kentucky facilities for inventory and distribution to customers.

         The Bridgeport, New Jersey facility manufactures all of the
Company's one-step diagnostic tests for the detection of microorganisms as
well as kits sold into the human clinical laboratory market. Proprietary
monoclonal and polyclonal antibodies are produced as needed in laboratories
at the New Jersey operations. Additional laboratory personnel prepare
reagents and perform quality assurance functions. Final kit assembly,
packaging and shipping are all performed in specific designated areas within
the New Jersey facility. The manufacture of the one-step diagnostic tests
requires the use of several custom-designed machines which enable
manufacturing personnel to achieve high-volume output on a per-hour basis.

         Manufacturing diagnostic tests for natural toxins, pesticides and
plant disease diagnostic tests takes place at the Company's corporate
headquarters in Lansing, Michigan. Proprietary monoclonal and polyclonal
antibodies for the Company's diagnostic kits are produced on a regular
schedule in the Company's immunology laboratories in Lansing. Other reagents
are similarly prepared by the chemistry group. These component parts are then
transferred to another section in the same building, where final kit assembly
and quality assurance are conducted, and shipping takes place.

         The Company purchases component parts and raw materials from over
200 suppliers. Though many of these supplies are purchased from a single
source in order to achieve the greatest volume discounts, the Company
believes it has identified acceptable alternative suppliers for all of its
components and raw materials.

         Shipments of products are generally accomplished within a 48-hour
turnaround time. As a result of this quick response time, the Company does
not maintain a large backlog of unshipped orders.

Competition

         The Company knows of no competitor that is pursuing its fundamental
strategy of developing a full line of products ranging from disposable tests
to veterinary instruments for a large number of food safety and animal safety
concerns. However, the Company does have competitors for each of its primary
product lines. The Company competes with a large number of companies ranging
from very small businesses to divisions of large companies. Many of these
firms have substantially greater financial resources than the Company.

         Academic institutions and other public and private research
organizations are also conducting research activities and may commercialize
products on their own or through joint ventures. The existence of competing
products or procedures that may be developed in future years may adversely
affect the marketability of the products developed by the Company.

         The Company competes primarily on the basis of ease of use, speed,
accuracy, and other similar performance characteristics of its products. The
breadth of the Company's product line, the effectiveness of its sales and
customer service organizations and pricing are also components in the
Company's competitive plan. The Company is not aware of any factors within
its product lines that place the Company in a negative competitive position
relative to its competitors.

Governmental Regulation

         A significant portion of the Company's products are affected by the
regulations of various domestic and foreign government agencies, including
the U.S. Department of Agriculture and the U.S. Food and Drug Administration.
A significant portion of the Company's revenue is derived from products used
to monitor and detect the presence of residues that are regulated by various
government agencies. Furthermore, a significant portion of the Company's
growth may be affected by the implementation of new regulations such as the
U.S. Food and Drug Administration's final rule, Procedures For The Safe and
Sanitary Processing And Importing of Fish and Fishery Products, and the final
rule of the U.S. Department of Agriculture, Pathogen Reduction; Hazard
Analysis and Critical Control Point Systems.

         The Company's development and manufacturing processes involve the
use of certain hazardous material, chemicals and compounds. The Company
believes that its safety features for handling and disposing of such
commodities comply with the standard prescribed by local, state and federal
regulations. The Company's cost to comply with these regulations is not
significant and the Company has no reason to believe that any such future
legislation or rules would be materially adverse to its business.

Employees

         Currently, the Company employs approximately 210 full-time persons.
None of the employees are covered by collective bargaining agreements. There
have been no work stoppages or slow downs due to labor-related problems. The
Company believes that its relationship with its employees is good. All
employees having access to proprietary information have executed
confidentially agreements with the Company.

Insurance

         The Company maintains product liability insurance on all products
with a coverage limit of $3 million per occurrence. In addition, the Company
also maintains insurance in amounts and types which the Company believes to
be customary in its industry.

ITEM 2.  PROPERTIES

         The Company's corporate offices and Michigan-based manufacturing and
research facilities are maintained in a 26,000 square foot building located
in Lansing, Michigan. This facility was purchased by the Company on land
contract in August 1985 and is fully paid for. The Company also owns
facilities comprising 1,100 square feet within one block of the existing
corporate headquarters used for offices to accommodate ten persons employed
in sales and marketing functions.

         Veterinary instrument manufacturing operations are housed in a
34,000 square foot building located at 9355 West Byron Street in Schiller
Park, Illinois. The Company entered into a seven-year, non-cancelable
operating lease for this property effective August 1, 1993. The lease
agreement provides for annual lease payments of $100,300 for each of the
first two years with annual increases of approximately 3.5% thereafter for
the remainder of the lease.

         The Company's Kentucky operations are maintained in 23,000 square
feet of leased space in a three story building located at 628 East Third
Street in Lexington, Kentucky. The Company entered into a five-year,
non-cancelable operating lease for the space effective July 1, 1993.
Effective September 1, 1997, the lease was amended to extend the term of the
lease to August 31, 1999 and to provide for annual lease payments, including
all utilities, of $90,000.

         The AMPCOR Diagnostics, Inc. operations are housed in 9,200 square
feet of leased space on one floor in a building located at 603 Heron Drive,
Bridgeport, New Jersey. The Company entered into a three-year three-month,
non-cancelable operating lease for the space effective February 1, 1995. On
January 22, 1998, the lease was amended to extend the lease term to November
1, 1999 and, effective May 1, 1998, provides for annual lease payments of
$38,960 plus additional rent equal to $8,268 per year with the additional
rent subject to annual increase based upon actual increases to certain
operating expenses.

         The Company's Florida manufacturing operations are maintained in
5,200 square feet of leased space at 5910 Breckenridge Center Parkway, Tampa,
Florida. The leased facilities are subject to a non-cancelable operating
lease that expires September 30, 1998 and that provides for annual lease
payments of approximately $44,000 including the Company's share of certain
operating expenses and property taxes. The Company negotiated a new three
year non-cancelable operating lease for the same facilities that commences on
October 1, 1998. The new lease provides for annual lease payments of $31,422
in year one increasing 4% in years two and three. In addition, the new lease
provides for additional lease payments for operating expenses and property
taxes estimated to be $13,625 annually and subject to increases based on
actual costs incurred.
<PAGE>
         Management believes that the Company's operating facilities are
suitable for conducting its current business, but also believes that
additional facilities will be required as a result of anticipated growth in
sales and personnel.

ITEM 3.  LEGAL PROCEEDINGS

         In August, 1996, the company initiated a lawsuit in the U.S.
District Court for the Western District of Michigan, Southern Division
against Arthur J. Trickey and Arthur M. Trickey ("Mr. Trickey"). This
litigation involves a dispute over a letter of intent the Company entered
into with Mr. Trickey to distribute certain products Mr. Trickey alleged he
had developed. The action seeks a ruling that the letter of intent is not a
binding contract, and recovery of damages in connection with overcharges,
other breaches, as well as for trademark infringement. Mr. Trickey has filed
counterclaims alleging a common law right to the disputed trademark. If the
Company prevails in its claims against Mr. Trickey, the Company does not
expect to be able to collect any significant damages. If Mr. Trickey prevails
in his counterclaims, the Company believes its exposure will not be
significant since sales under the disputed trademark to date have been
modest.

         The Company also filed a lawsuit against Vicam, L.P., Vicam
Management Corporation and Jack L. Radlo ("Vicam") in August, 1996 in the
U.S. District Court for the Middle District of Florida. The Company is suing
to recover damages the Company incurred in the character of lost sales of its
new aflatoxin detection kit caused by Vicam's publication of the false
allegation that Vicam's kit violates two patents licensed to Vicam. The
Company has two independent expert patent opinions that conclude that the
Company's product does not infringe Vicam's licensed patents. Vicam has
filed a counterclaim alleging that the Company's aflatoxin detection product
infringes one patent licensed to Vicam. The amount of the Company's damages
(lost sales) should it prevail have not yet been quantified. If Vicam were to
prevail, the Company believes that their damages would be relatively
insignificant since the Company's sales of this product have not been
material.

         In April 1998, Stephen C. Edberg, Stephen C. Wardlaw and Idexx
Laboratories, Inc. initiated a lawsuit against the Company in the U.S.
District Court for the District of Connecticut claiming patent infringement
and trade dress violations. The Company has filed a motion to dismiss for
lack of personal jurisdiction and/or improper venue. This litigation is at a
very early stage and the Company denies all liability related to this action.
Furthermore, the Company does not believe it will suffer any significant
damages should the competitor prevail since sales of the product in question
have been modest.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

         The information in this Management's Discussion and Analysis of
Financial Condition and Results of Operations contains both historical
financial information and forward-looking statements. Neogen does not provide
forecasts of future financial performance. While management is optimistic
about the Company's long-term prospects, historical financial information may
not be indicative of future financial performance.

         Forward-looking statements included herein involve certain risks and
uncertainties. Various factors, including competition, recruitment of and
dependence on key employees, impact of weather on agriculture and food
production, identification and integration of acquisitions, research and
development risks, patent and trade secret protection, government regulation
and other risks detailed from time to time in the Company's reports on file
at the Securities and Exchange Commission may cause actual results to differ
materially from those contained in the forward-looking statements.

</TABLE>

         The strong growth in diagnostic product sales was due to several
factors. The acquisitions of Vetoquinol U.S.A., Inc., effective December 30,
1997 and Triple Crown, effective July 1, 1997 accounted for $2,499,000 in
increased sales. Greater demand for test kits and other products sold to the
professional equine market contributed $538,000 in higher sales while sales
of test kits and reagents for pharmacologics were up $145,000. Diagnostic
test kits sold to the meat and poultry market for the detection of
microorganisms such as E. coli O157:H7 and Salmonella increased $644,000, or
93%, in 1998 compared to 1997.

         Offsetting these increases in diagnostic product sales was a
$725,000 or 22% decline in sales of test kits used for the detection of
vomitoxin. Sales of diagnostic tests for the detection of mycotoxins,
including vomitoxin, are influenced by the uncertainty of weather which
impacts growing conditions for grains, nuts and spices. Management discussed
its belief that sales of vomitoxin test kits would likely decline in the
current fiscal year in the company's 10-KSB for the year ended May 31, 1997.

         The increase in veterinary instrument sales was primarily the result
of sales to a new customer of specialty syringes and needles used to inject
marinades and spices into various red and white meats.

</TABLE>

         Costs of goods sold increased $1,759,000 in fiscal year 1998, mostly
as a result of the overall increase in product sales. In addition, raw
material expense increased substantially due to a change sales mix. Sales of
products sold to the professional equine market, which carry a higher
material cost increased significantly while sales of diagnostic test kits to
detect vomitoxin, which have a much lower material cost, declined. Management
expects raw material cost to continue to run higher, both in dollars and as a
percent of sales, in the fiscal year ending, May 31, 1999.

<PAGE>
         The increase in sales and marketing expense for the year is
primarily due to higher costs, including the acquisitions of Triple Crown and
Vetoquinol, U.S.A., Inc., associated with marketing products to the
professional equine market. Salaries, fringe, recruiting, relocation,
commissions, royalties, travel, advertising and promotions all showed
increases compared to the prior year, which, in total amounted to $583,000.

         The majority of the increase in general and administrative expense
in fiscal 1998 is the result of higher cost in two categories. Consulting
expense was $178,000 higher due primarily to contract services associated
with a new computer installation, increased consulting pertaining to
manufacturing and approvals for professional equine products and also because
of management consulting pertaining to the company's Ampcor Diagnostic, Inc.
subsidiary.

         In addition, legal and professional fees increased $202,000 compared
to the prior year. Management believes that the company is not involved in
any material adverse legal proceedings. However, Neogen is a party in several
lawsuits as discussed in ITEM 3. LEGAL PROCEEDINGS in the Company's Form
10-KSB for the year ended May 31, 1998. Management intends to vigorously
pursue this litigation and cannot predict the outcome of these lawsuits.
Furthermore, the company has no way to predict the level of expenses that may
be incurred in fiscal year 1999 in pursuing this litigation.

</TABLE>


         Other income was $333,000 higher than last year. In October 1996,
the Company completed a public offering of common stock. A portion of the
proceeds was used to pay down short-term bank borrowings, resulting in lower
interest expense. The remaining proceeds were invested in short-term
marketable securities, which has resulted in higher interest income. In
addition, the Company's share of royalties, paid to an affiliated
partnership, increased significantly compared to the prior year.

</TABLE>

         The increase in net income and net income per share is the direct
result of the increase in sales of diagnostic products, including
acquisitions, along with the increase in other income.

         Neogen's effective federal tax rate has been insignificant because
the company has had net operating loss carryforwards available to offset
taxable income. Upon utilization of its remaining net operating loss
carryforwards, Neogen's effective federal tax rate will increase
significantly.

Financial Condition and Liquidity

         At May 31, 1998 the Company had $10,589,000 in cash and marketable
securities, working capital of $17,192,000 and stockholders' equity of
$23,609,000. In addition, the Company has bank lines of credit totaling
$10,000,000 with nothing borrowed against these lines as of May 31, 1998.
Cash and marketable securities decreased $2,455,000 during fiscal year 1998
as a result of the acquisitions of certain assets of W.J. Bartus, Inc. and
Vetoquinol U.S.A., Inc..

         Effective July 1, 1997 the Company acquired substantially all of the
assets of Triple Crown Pharmaceuticals, a division of W.J. Bartus, Inc. of
Ft. Pierce, Florida. The initial purchase price consisted of a cash payment
of approximately $1,400,000 paid in July, 1997. A second and final cash
payment of up to $500,000 will be paid in fiscal year 1999 provided the
seller meets certain conditions of the asset purchase agreement. Effective
December 30, 1997 the Company acquired certain assets of Vetoquinol, U.S.A.,
Inc. located in Tampa, Florida. The initial purchase price consisted of a
cash payment of approximately $2,035,000 paid at closing and a second cash
payment of approximately $153,000 paid in April, 1998.

         Accounts receivable are higher at May 31, 1998 than May 31, 1997
partially as a result of the aforementioned acquisitions and partially
because of higher sales volume during the last quarter of fiscal 1998
compared to the last quarter of fiscal 1997. Inventories are higher at May
31, 1998 as a result of the acquisitions, to support increases in sales of
professional equine products and in anticipation of future increases in sales
volume.

         The increase in goodwill and other non-current assets at May 31,
1998 compared to May 31, 1997 was due to the previously discussed
acquisitions. Accounts payable decreased $264,000 partially due to lower
trade payables for inventory at May 31, 1998 and also due to the timing of
year-end cut-offs and scheduled payment dates for trade payables.

         The Company did not borrow any additional funds during fiscal year
1998 and made scheduled payments on long-term debt totaling $56,000. Neogen
expended approximately $646,000 during 1998 for additions to property,
equipment and other assets. At May 31, 1998 the Company had no material
commitments for capital expenditures. Inflation and changing prices are not
expected to have a material effect 

                                     -13-

<PAGE>

on the Company's operations.

         Neogen has been profitable for twenty of its last twenty-one
quarters and has generated positive cash flows from operations during this
period. Management believes that the Company's existing cash and marketable
securities at May 31, 1998, along with its available bank lines of credit and
cash expected to be generated from future operations, will be sufficient to
fund activities for the foreseeable future. However, existing cash and
marketable securities may not be sufficient to meet the Company's cash
requirements to commercialize products currently under development or its
plans to acquire additional technology and products that fit within the
Company's mission statement. Accordingly, the Company may be required to
issue equity securities or enter into other financing arrangements for a
portion of the Company's future capital needs.


Year 2000

         The company believes that its financial and manufacturing systems
are year 2000 compliant with the exception of the financial software used at
its Ideal Instruments subsidiary. The Company plans on implementing software
changes by November 30, 1998 at the Ideal Instruments subsidiary to ensure
year 2000 compliance. The Company does not expect implementation of these
changes to have a material impact on its results of operation. The Company's
operations with respect to the year 2000 may also be affected by other
entities with whom it transacts business. The Company is currently unable to
determine the potential impact, if any, that could result from such entities'
failure to adequately address this issue.

Neogen Corporation and Subsidiaries

Report of Independent Certified Public Accountants



To the Board of Directors
Neogen Corporation
Lansing, Michigan

We have audited the accompanying consolidated balance sheets of Neogen
Corporation and subsidiaries as of May 31, 1998 and 1997, and the related
consolidated statements of income, stockholders' equity and cash flows for
the years then ended. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on
these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements.
An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Neogen
Corporation and subsidiaries at May 31, 1998 and 1997, and the results of
their operations and their cash flows for the years then ended in conformity
with generally accepted accounting principles.

1.    Summary of Accounting Policies

Nature of Operations

Neogen Corporation and subsidiaries (the Company) develop, manufacture, and
sell a diverse line of products dedicated to food and animal safety. The
Company's products are currently used for animal health applications, food
safety testing and in medical research.

Basis of Consolidation

The consolidated financial statements include the accounts of Neogen
Corporation, Ideal Instruments, Inc. (Ideal), AMPCOR Diagnostics, Inc.
(AMPCOR) and several majority owned companies which are general partners for
research limited partnerships. The investments in partnerships are not
significant to the consolidated financial statements.

All significant intercompany accounts and transactions have been eliminated
in consolidation.

Use of Estimates

In preparing financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and
assumptions that affect (1) the reported amounts of assets and liabilities
and the disclosure of contingent assets and liabilities as of the date of the
financial statements, and (2) revenues and expenses during the reporting
period. Actual results could differ from these estimates.

Risks and Uncertainties

Diagnostic products, specifically test kits for the detection of vomitoxin,
contribute a significant portion of the Company's revenues and profits. The
Company expects that its ability to maintain or expand its current levels of
revenues and profits in the future will depend on various factors, including
the impact of weather on agriculture and food production.

Concentrations of Credit Risk

Financial instruments which potentially subject the Company to concentrations
of credit risk consist principally of accounts receivable. The Company
attempts to minimize credit risk by reviewing all customers' credit history
before extending credit and by monitoring customers' credit exposure on a
continuing basis. The Company establishes an allowance for possible losses on
accounts receivable based upon factors surrounding the credit risk of
specific customers, historical trends and other information.

Fair Values of Financial Instruments

The carrying amounts of accounts receivable, accounts payable, and accrued
expenses approximate fair value because of the short maturity of these items.

The carrying amounts of the notes payable and long-term debt issued pursuant
to the Company's bank credit agreements approximate fair value because the
interest rates on these instruments change with market rates.

Marketable Securities

All marketable securities are classified as available-for-sale and are
available to support current operations or to take advantage of other
investment opportunities. These securities are stated at estimated fair
market value. The cost of securities sold is based on the specific
identification method and interest earned is included in other income.

Inventories

Inventories are stated at the lower of cost, determined on the first-in,
first-out method, or market. The components of inventories are as follows:

                           ==========             ==========
</TABLE>

Property and Equipment

Property and equipment is stated at cost. Expenditures for major improvements
are capitalized while repairs and maintenance are charged to expense.
Depreciation is provided on the straight-line method over the estimated
useful lives of the respective assets, generally twenty to thirty-one years
for buildings and improvements and three to ten years for furniture,
machinery and equipment. Depreciation expense was $469,324 and $389,582 in
1998 and 1997, respectively.

Intangible Assets

Goodwill represents the excess of acquisition costs over the estimated fair
value of net assets acquired. Goodwill is amortized on a straight-line basis
over periods ranging from fifteen to twenty-five years. The Company reviews
goodwill for impairment based upon undiscounted cash flows from operations
before interest over the remaining lives of the goodwill. If necessary,
impairment will be measured based on the difference between discounted future
cash flows and the net book value of the related goodwill.

Other intangible assets, consisting primarily of covenants not to compete,
licenses and patents, are recorded at fair value at the date of acquisition.
These intangible assets are amortized on a straight-line basis over periods
ranging from five to seventeen years.

Long-lived Assets

The Company reviews the carrying values of its long-lived assets for possible
impairment whenever events or changes in circumstance indicate that the
carrying amount of the assets may not be recoverable. The Company evaluates
whether impairment exists on the basis of undiscounted future cash flows from
operations before interest for the remaining useful life of the assets. Any
long-lived assets held for disposal are reported at the lower of these
carrying amounts or fair value less costs to sell.

Revenue Recognition

The Company recognizes product sales at the time of shipment.

Earnings Per Share

In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 128, "Earnings per Share." SFAS 
No. 128 replaced the previously reported primary and fully diluted earnings 
per share with basic and diluted earnings per share. Unlike primary earnings 
per share, basic earnings per share excludes any dilutive effects of options,
warrants, and convertible securities. Diluted earnings per share is very
similar to the previously reported fully diluted earnings per share. All
earnings per share amounts for all periods have been presented, and where
necessary, restated to conform to the SFAS No. 128 requirements. The
following table presents the earnings per share calculations:

Options to purchase 33,400 and 128,500 shares of common stock at prices
ranging from $11.31 to $13.25 and $7.50 to $9.25 in 1998 and 1997
respectively, were outstanding, but were not included in the computation of
diluted earnings per share because the option's exercise price was greater
than the average market price of the common shares.

Recent Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income," and SFAS No. 131 "Disclosures about
Segments of an Enterprise and Related Information." These statements are
effective for financial periods beginning after December 15, 1997 and require
comparative information for earlier years to be restated. Management has not
determined the impact, if any, these statements may have on future financial
statement disclosures.

Statement of Position (SOP) 98-5, "Reporting on the Cost of Start-Up
Activities," was issued in April 1998 and SFAS 133, "Accounting for
Derivative Instruments and Hedging Activities," was issued in June 1998.
These statements are effective in fiscal 2000 and are not expected to have a
material impact on the consolidated financial statements.

2.    Marketable Securities

The Company currently invests in only high quality, short-term investments
with maturity dates of less than one year, which are classified as
available-for-sale. As such, there were no significant differences between
amortized cost and estimated fair market value at May 31, 1998 and 1997.
Additionally, since investments are short-term and are generally allowed to
mature, realized gains and losses for both years have been minimal. The
following table presents the estimated fair value breakdown of investment by
category:

3.    Acquisitions

Effective July 1, 1997, Neogen acquired certain assets of Triple Crown, a
division of W.J. Bartus, Inc. of Fort Pierce, Florida. The acquisition was
accounted for by the purchase method and all acquired assets, consisting of
inventory, fixed assets and 20 related products were moved to the Company's
Lexington, Kentucky division.

The initial purchase price consisted of a cash payment of approximately
$1,400,000, resulting in goodwill of approximately $900,000. Additional
consideration in the amount of approximately $500,000 is expected to be paid
in fiscal 1999 based upon the seller meeting certain conditions of the asset
purchase agreement.

Effective December 30, 1997, Neogen acquired certain assets of Vetoquinol,
U.S.A., Inc. located in Tampa, Florida. The acquisition was accounted for by
the purchase method. Neogen plans to continue to operate the production
facility in Tampa and has relocated all sales and administrative functions to
the Company's Lexington, Kentucky facility.

The purchase price consisted of initial consideration of approximately
$2,035,000 in cash paid at closing. A second cash payment of approximately
$153,000 was paid in April, 1998. The cumulative purchase price resulted in
goodwill of approximately $1,250,000. Additional consideration not to exceed
$200,000 may be paid based upon operating performance for the twelve month
periods ending December 31, 1998 and 1999.

Proforma results of operations are not presented as the effect of the
acquisitions was not material to the consolidated results of operations of
the Company for the year ended May 31, 1998.

4.    Notes Payable and Long-Term Debt

The Company and its subsidiaries have available working capital
lines-of-credit and borrowing arrangements with banks totaling $2,500,000. At
May 31, 1998 and 1997, there were no borrowings outstanding. These
arrangements bear interest from the prime rate less .50% to the prime rate
plus .75% (the prime rate was 8.50% at May 31, 1998), and are collateralized
by substantially all assets of the Company and its subsidiaries.

In addition, the Company maintains an unsecured acquisition line-of-credit in
the amount of $7,500,000 at the prime rate less .50%. There were no
borrowings on this line-of-credit at May 31, 1998.

The term note is payable in sixty monthly installments of $4,056 plus
interest at the prime rate less .50% and is collateralized by substantially
all the assets of Neogen and AMPCOR.

The terms of certain financing agreements contain, among other provisions,
the requirements to meet certain financial ratios and levels of working
capital and tangible net worth, and restrict the payment of dividends.

Maturities of long-term debt are: 1999 - $48,672; 2000 - $48,672; 2001 -
$48,672; 2002 - $48,672; and 2003 - $28,376.

5.  Public Stock Offering

On October 22, 1996, the Company sold to the public 1,500,000 shares of
common stock at a price of $7.50 per share. The net proceeds to the Company
after deducting underwriting commissions and other expenses of the offering
were approximately $10,201,000.

6.  Stock Options and Stock Warrants

The Company maintains Stock Option Plans (the Plans) under which qualified
and non-qualified options to purchase shares of common stock may be granted
to eligible directors, members of the Scientific Review Council, officers, or
employees of the Company at an exercise price of not less than the fair
market value of the stock on the date of grant. The number of shares
authorized for issuance under the Plans is 1,459,375. At May 31, 1998,
options have been granted with three to five year vesting schedules and
option terms of five to ten years. A total of 366,600 shares were available
for future grants under the Plans.

The Company applies Accounting Principles Board Opinion No. 25 in accounting
for its stock option plans. Accordingly, no compensation cost has been
recognized for the Plans. Had compensation expense for the Company's stock
option plans been determined based on the fair value at the grant dates
consistent with the method of SFAS No. 123, the Company's net income and
earnings per share would have been the following pro forma amounts:

The fair value of each option granted is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted-average
assumptions for grants in 1998 and 1997, respectively: dividend yield of 0%
for both years: expected volatility of 55.0% and 68.0%; risk free interest
rates of 6.0% and 6.5%; and expected lives of four years for 1998 and from
five to ten years for 1997.

The weighted-average grant date fair value of options granted in 1998 and
1997 was $4.32 and $4.38, respectively.

7.  Taxes On Income

Income taxes are calculated using the liability method specified by SFAS No.
109 "Accounting for Income Taxes."

As of May 31, 1998, the Company has net operating loss carryforwards of
approximately $670,000 for income tax purposes which expire between 2002 and
2008. In addition, the Company has approximately $370,000 of tax credit
carryforwards, the majority of which expire between 1999 and 2010.
Approximately $90,000 of the tax credit carryforwards have no expiration.

Deferred income taxes reflect the tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial
reporting purposes and the amounts used for income tax purposes. Significant
components of the Company's deferred tax liabilities and assets as of May 31,
1998 and 1997 are as follows:

SFAS No. 109 requires that a valuation allowance be recorded against tax
assets which are not likely to be realized. The Company's carryforwards
expire at specific future dates. Due to the uncertain nature of their
ultimate realization based upon past performance and the difficulty
predicting future results, the Company has established a full valuation
allowance against these carryforward benefits and is recognizing the benefits
only as reassessment demonstrates they are realizable. The need for this
valuation allowance is subject to periodic review. If the allowance is
reduced, the tax benefits of the carryforwards will be recorded in future
operations as a reduction of the Company's income tax expense.

The reconciliation of income taxes computed at the U.S. federal statutory tax
rates to income tax expense for the years ended May 31, 1998 and 1997 is as
follows:

the Main Price.

               (b) Buyer shall pay Seller by bank wire transfer at Closing an
amount equal to seventy percent (70%) of Two Hundred Sixty-Nine Thousand

mutual agreement of the parties. A final adjustment in payment or refund
shall take place at a post closing on the one hundredth day after Closing
("Post Closing"). Buyer shall present at the Post Closing a statement
certifying the amount of the Receivables that have been collected through
that date and include an accounting of collected and uncollected Receivables.
To the extent that the amount collected by Buyer from the Receivables between
Closing and Post Closing exceeds the Preliminary Receivables Price, Buyer
shall pay this amount to Seller in cash. To the extent that the amount

place at Post Closing. Buyer shall present at the Post Closing a statement
certifying the amount of the Inventories determined pursuant to Section 1(e)
("Inventories Price"). To the extent that the Inventories Price exceeds the

To the extent that the Inventories Price is less than the Preliminary
Receivables Price, Seller shall refund this amount to Buyer in cash.
Adjustment of Inventories will be limited to correction of physical counts,
recording the amount at the lower of cost or average current selling price or
mathematical errors ("Changes"). Buyer shall give Seller a list of all

after Closing, Buyer will pay a secondary payment to Seller of up to One
Hundred Thousand Dollars ($100,000.00) as to the Purchased Assets except
Receivables and Inventories. This secondary payment shall be calculated as
follows: Net Sales of all P. acnes products from January 1, 1998 through
December 31, 1998 shall be used as a base ("Base"). One Million Two Hundred
Thousand Dollars ($1,200,000.00) shall be subtracted from the Base ("Net
Amount"). The Net Amount shall be multiplied by ten percent (10%) and shall
constitute the second payment; provided the second payment shall not be less
than zero ($0) nor greater than One Hundred Thousand Dollars ($100,000.00).

               (e) Within thirty (30) days following the second anniversary
after Closing, Buyer will pay a third payment to Seller of up to One Hundred
Thousand Dollars ($100,000.00) as to the Purchased Assets except Receivables
and Inventories. This third payment shall be calculated as follows: Net Sales
of all P. acnes products from January 1, 1999 through December 31, 1999 shall
be used as a Base. One Million Two Hundred Thousand Dollars ($1,200,000.00)
shall be subtracted from the Base. The Net Amount shall be multiplied by ten
percent (10%) and shall constitute the third payment; provided such payment
shall not be less than zero ($0) nor greater than One Hundred Thousand
Dollars ($100,000.00).

               (f) The term "Net Sales" shall mean the total of the aggregate
gross invoice prices of P. acnes products of Buyer, less the sum of (i) cash,
trade or quantity discounts; (ii) sales, use, tariff, import/export duties or
other excise taxes imposed upon particular sales; (iii) transportation
charges; and (iv) allowances or credits to customers because of rejections or
returns. Concurrently with its delivery of payment, Buyer shall furnish to

amounts for the relevant period. Buyer shall furnish to Seller a quarterly

               (h) The purchase price to be paid by Buyer shall be allocated
in the manner required by Section 1060 of the Internal Revenue Code of 1986,
as amended ("Code"), and the Treasury Regulations promulgated thereunder. In
making the allocation, Buyer and Seller shall apply the fair market values
set forth on the Certificate of Allocation substantially in the form of

requirements of the Code.

               (i) Buyer agrees to maintain books and records to permit the

sound business judgment to generate Net Sales.

        4. The Closing. The parties agree that the effective date of closing

<PAGE>

               (a) Organization and Qualification. Seller is validly existing
and in good standing under the laws of the State of Florida. No failure on
the part of Seller to be qualified as a foreign corporation in any
jurisdiction materially and adversely affects the Business or financial
position or results of the operation of the properties of Seller by reason of
any disability affecting its right to own property, collect receivables,
enforce contracts or otherwise. Seller has the requisite corporate power and
authority to own all of the Purchased Assets and to carry on the Business as
it is now being conducted.

               (b) No Violation. Except as disclosed in Exhibit 5.b, the
execution and delivery of this Agreement by Seller and the consummation of
the transactions contemplated hereby will not violate any provision of law,
order, or regulation of any governmental authority, the corporate charter or
by-laws of Seller or constitute a default under any judgment, order or decree
of any court of governmental agency or instrumentality, or conflict or
constitute a breach or a default under any material agreement to which the
Seller is a party or by which it is bound.

               (c) Financial Information. Seller has provided in Exhibit 5.c
its (i) unaudited balance sheet and statements of income, stockholders equity
and cash flows as of and for the period ended December 31, 1996 ("Financial
Statements"); and (ii) interim financial statements for the periods ending

                      (1) Have been prepared in accordance with the books of
account and records of Seller.

                      (2) Fairly present Seller's financial condition and the
results of its operation as of and for the periods therein specified, subject

on a consistent basis.

               (d) Title to Assets. Seller owns and has corporate power to
own, and has good and marketable title to all of the Purchased Assets free
and clear of liens, security interests, mortgages, pledges, claims or
encumbrances of any kind whatsoever, except as shown in Exhibit 5.d.i. Seller
has delivered to Buyer true and complete copies of all leases, contracts,
agreements, options and commitments relating to the Purchased Assets that are
listed on Exhibit 1(f). All such leases, contracts, agreements, options and
commitments are legally valid and binding and in full force and effect, and
there are no defaults or breaches by Seller thereunder or counterclaims or
defenses against it. Seller has received no notice of any default, breach,
counterclaim or offset by any other party to such leases, contracts,
agreements, options and commitments, nor does Seller have any knowledge
thereof.

               (e) Condition of Assets. Notwithstanding anything to the
contrary in this Agreement, Seller does not warrant to Buyer the physical
condition of the Machinery and Equipment, and Buyer shall accept the
Machinery and Equipment "as is" on the Closing Date in their then-current
physical condition. Seller makes no warranties or representations, either
express or implied, as to any matter whatsoever relating to the condition of
the Machinery and Equipment, including without limitation, the design and
condition of the Machinery and Equipment, their merchantability, quality,
suitability, or fitness for any particular purposes and without limiting the
generality of the foregoing, Seller shall not be liable for any deft, either
latent or patent, in the condition of the Machinery and Equipment or for any
direct or consequential damages therefrom.

               (f) Trade Rights. To Seller's knowledge, no Products
manufactured and sold by any manufacturing process employed by Seller
conflicts with or infringes on any United States or foreign patent of others
and Seller has not received any notice of such a claim. The parties
acknowledge that the Intangible Property consists of know-how that is not
protected by patents or other legally enforceable claim (except as set forth
in any confidentiality agreements with employees or independent contractors).
To Seller's knowledge, no trade secret associated with the Products has been
misappropriated or has been challenged or threatened in any way.

               (g) Receivables. The list of Receivables attached as Exhibit
1.d is a complete and accurate list of all the Receivables as of December 30,
1997. All of the Receivables listed on Exhibit 1.d arose from bona fide sales
transactions of Seller, and no portion of the Receivables is subject to
counterclaim or offset or is otherwise subject to a notice of dispute.

               (h) Inventories. The Inventories are reflected on the
Financial Statements and the Inventories are recorded at the lower of cost or
average selling price. No Inventories have been consigned to others.

               (i) Contracts. Exhibit 5.d.ii describes all material Contract
Rights to which Seller is a party or to which it is bound and which arose out
of, or relate to, the Purchased Assets, which extend beyond the Closing Date.
True and correct copies of all such documents evidencing the Contract Rights
have been delivered by Seller to Buyer.

               (j) Litigation. Except as disclosed in Exhibit 5.(j), there
are no actions, suits, proceedings or investigations pending or to Seller's
knowledge, threatened against Seller at law or in equity, or before any

                      (1) Generally. Seller agrees to defend, indemnify and
hold Buyer harmless from and against any and all loss, damage, claims and
expenses (including accountants' and attorneys' fees) incurred by Buyer which
Buyer may sustain at any time by reason of (i) the breach of any of the
Representations (including all items disclosed in the Exhibits) made by
Seller herein or any agreement or document delivered in connection with this
Agreement or with the closing of the transactions contemplated hereby, (ii) a
Product Claim arising from Seller's sales before the Closing Date; or (iii)
Buyer being deemed to be a "successor" employer to Seller for purpose of
COBRA obligations ("Indemnifiable Damage"). Buyer shall have the right to set
off any Indemnifiable Damage it may incur against the amount it owes Seller
("Disputed Amount"); provided the Disputed Amount is placed in escrow until
resolved according to the terms of the Agreement. This right of set off shall
be in addition to any other rights Buyer may have against Seller. Buyer
agrees to defend, indemnify, and hold harmless Seller from and against any
and all loss, damage, claims, and expenses (including accountants' and
attorney's fees) incurred by Seller that Seller may sustain by reason of (i)
the breach of any of the Representations (including all of the items
disclosed in the Exhibits) made by Buyer herein or in any agreement or
document delivered in connection with this Agreement or with the closing of
the transactions contemplated by this Agreement; or (ii) any liability
assumed by Buyer pursuant to this Agreement or the other documents delivered
in connection with this Agreement; or (iii) otherwise arising out of the
ownership by Buyer of the Purchased Assets or the operation of the Business
on or after the Closing Date (including, without limitation, Product Claims
arising from Buyer's sales following the Closing Date). Buyer shall be
entitled to indemnification only if its claim is made within the applicable
time period specified in Section 9.(a).

                      (2) Procedure for Indemnity. On the occurrence of any
event that could give rise to a claim against, or to a right of defense and
indemnity by, Buyer or Seller pursuant to this Agreement, or in the event
that any suit, action, investigation, claim or proceeding is begun, made or
instituted against Buyer or Seller as a result of which the other may become
obligated under this Agreement, the party claiming indemnification (the
"Indemnified Party") shall so notify the other party (the "Indemnifying
Party"). The Indemnifying Party will be relieved from any obligation to
provide indemnity to the extent its ability to defend the claims is
materially prejudiced by a notice delay. After receipt of the notice, the
Indemnifying Party shall have the right to promptly undertake to defend,
contest, or otherwise protect against any such event or any suit, action,
investigation, claim or proceeding arising thereform, using counsel of its
choice. The Indemnified Party, at its own cost, may elect to participate in
the defense using counsel of its choice. Buyer and Seller shall cooperate in
defending against any claim to which indemnity obligations apply, and in
minimizing the costs, losses and damage involved in such claim. Neither party
will compromise, settle, or admit liability in any claim to which 

                                     -20-

<PAGE>

the other party's indemnity obligations apply, and will not incur significant
costs or expenses with respect to any such claim, without the consent of the
other party, which shall not be unreasonably withheld.

                      (3) Limit of Liability. Anything in Section 9 to the
contrary notwithstanding, Seller's maximum amount of Indemnifiable Damages
shall be limited to the total purchase price paid to it pursuant to Section 3
of the Agreement as to Section 2, Section 5.d., j., k., l., o., v., w., z.,
and (cc), Section 15, and any knowing misrepresentation. Seller shall not
have any liability for the remaining warranties in Section 5 after the
aggregate amount of Indemnifiable Damages paid by Seller exceeds $250,000.
The sole recourse of either party for a breach of any representation or
warranty shall be pursuant to this section.

        10.    Collection of Receivables:

               (a) Buyer shall use its best efforts to collect the
Receivables as promptly as possible following the Closing. Buyer shall first
consult with and obtain Seller's consent to any compromise of any of the
Receivables that results in collection of less than 90% of its face value or
that defers payment for more than thirty days. Buyer shall have no duty to
undertake collection steps, other than routine billing.

               (b) Any Receivables acquired as part of the Purchased Assets
which remain uncollected on the one hundredth day after the Closing Date
shall be reassigned to Seller and an amount equal to such uncollected
Receivables shall be deducted from the amount owed Seller at the Post
Closing. In its internal accounting, Seller shall assign funds received from
a customer first to those invoices designated for payment by the customer,
and if not designated, to the oldest invoice of the customer.

                                     -21-

        11.    Employees.

               (a) Seller agrees to terminate the employment of those
individuals shown in Exhibit 11 on or the day before the Closing Date.

               (b) Buyer shall use its best efforts to hire the employees
listed in Exhibit 11.

        12.    Transactions Subsequent to Closing.

               (a) Further Assurances. Buyer and Seller agree that, from time
to time after Closing, and upon reasonable request, they shall execute,
acknowledge and deliver such other instruments as reasonably may be required
to more effectively transfer and vest in Buyer the Purchased Assets or to
otherwise carry out the terms and conditions of this Agreement.

               (b) Maintenance of Seller. Until the Federal, state and local
income tax liabilities of Seller attributable for all periods ending on or
prior to the Closing have been examined and reported on by the Internal
Revenue Service (or closed by applicable statute of limitations) and finally
determined, Seller's legal existence shall be maintained and Seller shall
maintain at all times sufficient working capital to insure Seller's ability
to pay its tax obligations on a punctual basis.

               (c) Temporary Use of Vetoquinol Name. Buyer and Seller
acknowledge that some components of the Inventories bear Vetoquinol labels.
Seller grants to Buyer permission to sell these Inventories bearing the
Vetoquinol labels for up to twelve (12) months after the Closing. Buyer shall
use its best efforts to sell the Inventories that bear Seller's label as soon
as reasonably possible.

        13. Proper Notices. All notices and other communications required or

performance shall be governed in all respects by the laws of the State of

        15. Bulk Transfer. Buyer agrees to waive compliance with the

Seller's covenant to

<PAGE>

indemnify and hold Buyer harmless from and against all liabilities Buyer may
incur arising from such non-compliance.

        16. Integration. This Agreement and all schedules, exhibits and
agreements attached hereto set forth the entire agreements and understanding
between the parties as to the subject matter hereof, and supersedes all prior
discussions, representations, amendments or understandings of every kind and
nature between them including but not limited to the Confidentiality
Agreement entered into on September 26, 1997.

        17. Amendments. Any amendment, alteration, supplement, modification
or waiver shall be invalid unless it is set forth in writing, signed by the
party intending to be bound thereby.

        18. Severability. If any provision of this Agreement becomes or is

sale and distribution in those territories or for those product applications
as to which Buyer has the exclusive rights to market, register, manufacture,
and further develop particular product applications of P.acnes, except as
specifically licensed to Parent in the Rights Agreement. Seller and Parent
acknowledge that this non-compete applies to them whether they act
individually or jointly, alone, or as an officer, agent, employee, director,

the restrictions set forth above are considered by the parties to 

                                     -23-

<PAGE>

be reasonable in all circumstances, it is recognized that restrictions of the
nature in question may fail for technical reasons unforeseen and accordingly
it is hereby agreed and declared that if any of such restrictions shall be
adjudged to be void as going beyond what is reasonable in all the
circumstances for the protection of the interests of the Buyer but would be
valid if part of the wording thereof were deleted or the periods if any
thereof reduced or the range of activities or area dealt with thereby reduced

them constitute confidential information ("Confidential Information"). Seller
and Parent agree not to individually or jointly disclose to any person any
Confidential Information regardless of nature, type or physical manifestation
or any other information concerning the business affairs of Buyer and the
Business, including, but not limited to, information related to the products
identified in Item B of the Recitals and improvements made thereto, except as
specifically permitted in the Rights Agreement. This restriction shall
include information imparted or divulged to, gained or developed by, or
otherwise discovered by Seller in executing this Agreement. Anything in this
Agreement to the contrary notwithstanding, Seller and Parent shall not be
bound by this Paragraph 24 to the extent that the information they desire to
divulge is or becomes publicly known, other than through a breach of their
obligations hereunder or required by law.

        25. Construction of Agreement. The parties agree that this Agreement

               (a) Demand for Arbitration. Except regarding a claim for
fraud, rescission of the Agreement or violation of Sections 23 or 24, any
controversy, dispute or claim arising out of, in connection with, or in
relation to, the construction, performance or breach of this Agreement,
including without limitation, the validity, scope and enforceability of this

judgment on such award may be entered by either party in any court having
jurisdiction over the person or properly of the party against whom such award
is sought to be enforced. The parties stipulate that these arbitration
provisions shall be a complete defense to any suit, action or proceeding
instituted in any federal, state or local court, or before any administrative
tribunal with respect to any dispute, controversy or alleged breach of this
Agreement. The arbitration provisions of this Agreement shall survive any
termination or expiration of this Agreement.

fractional shares, and any fractional shares resulting from such adjustments
shall be eliminated from any outstanding option.

        6. Participants: Subject to Paragraph 11, the Committee shall
determine and designate from time to time, in its Discretion, those key
employees (including officers), directors, and SRC members of the Company or
any Subsidiary to whom options are to be granted and who thereby become
Participants under the Plan; provided, however, that (a) Incentive Options
shall be granted only to employees (as defined in the Code) of the Company or
a corporate Subsidiary, to the extent required by Section 422 of the Code, or
any successor provision, and (b) no Participant may be granted stock options
to purchase more than 100,000 Common Shares in the aggregate in any fiscal
year of the Company, subject to any adjustments provided in the final
paragraph of Paragraph 5 and in Paragraph 17.

        7. Allotment of Shares: Subject to Paragraph 11, the Committee shall
determine and fix the number of Common Shares to be offered to each

to any one Participant which would result in the aggregate fair market value,
determined as of the date the option is granted, of the underlying stock with
respect to which Incentive Options are exercisable for the first time by such
individual during any calendar year (under all of such plans of the Company
and its parent and Subsidiary corporations) exceeding $100,000.

                                     -3-

<PAGE>

        8. Option Price: Subject to the rules set forth in this Paragraph 8,
the Committee, in its Discretion, shall establish the option price at the
time any option is granted. Such option price shall not be less than 100% of
the fair market value of the stock on the date on which such option is
granted; provided that with respect to an Incentive Option granted to an
employee who at the time of the grant owns (after applying the attribution
rules of Section 424(d) of the Code) more than 10% of the total combined
voting stock of the Company or of any parent or Subsidiary, the option price
shall not be less than 110% of the fair market value of the stock subject to
the Incentive Option on the date such option is granted. Fair market value of
a share shall be determined by the Committee and may be determined by using
the closing sale price of the Company's stock on any exchange or other market
on which the Common Shares shall be traded on such date, or if there is no
sale on such date, on the next following date on which there is a sale, or
the average of the closing bid and asked prices in any market or quotation
system in which the Common Shares shall be listed or traded on such date. The
option price will be subject to adjustment in accordance with the provisions
of Paragraphs 5 and 17 of the Plan.

        9. Granting and Exercise of Options: The granting of options under
the Plan shall be effected in accordance with determinations made by the
Committee pursuant to the provisions of the Plan, by execution of instruments
in writing in form approved by the Committee. Such instruments shall
constitute binding contracts between the Company and the Participant.

        Subject to the terms of the Plan, the Committee, in its Discretion,
may grant to Participants Incentive Options, Nonqualified Options or any
combination thereof. Each option granted under the Plan shall designate the
number of shares covered thereby, if any, with respect to which the option is
an Incentive Option and the number of shares covered thereby, if any, with
respect to which the option is a Nonqualified Option.

        Subject to the terms of the Plan, each option granted under the Plan
shall be exercisable at any such time or times or in any such installments as
may be determined by the Committee in its Discretion; provided that the
aggregate fair market value (determined as of the date the option is granted)
of the underlying stock with respect to which Incentive Options are
exercisable for the first time by such individual during any calendar year
(under all of such plans of the Company and its parent and Subsidiary
corporations) shall not exceed $100,000. Except as provided in Paragraph14,
options may be exercised only while the Participant is an employee, director,
or SRC member of the Company or a Subsidiary.

        Notwithstanding any other term or provision of this Plan, but subject
to the requirements of the Code with respect to Incentive Options that are
intended to remain Incentive Options, in connection with a Participant
ceasing to be an employee of the Company or a Subsidiary for any reason, the
stock option agreement may provide for the acceleration of, or the Committee
may accelerate, in its Discretion (exercised at the date of the grant of the
stock option or after the date of grant), in whole or in part, the time or
times or installments with respect to which any option granted under this
Plan shall be exercisable in connection with termination of a Participant's
employment with the Company or a Subsidiary, subject to any restrictions,
terms and conditions 

                                     -4-

<PAGE>

fixed by the Committee either at the date of the award or at the date it
exercises such Discretion.

        Successive stock options may be granted to the same Participant,
whether or not the option or options previously granted to such Participant
remain unexercised. A Participant may exercise any option granted under the
Plan, if then exercisable, notwithstanding that options granted to such
Participant prior to the option then being exercised remain unexercised.

        10. Payment of Option Price: At the time of the exercise in whole or
in part of any option granted under this Plan, payment in full in cash, or
with the consent of the Committee, in its Discretion, in Common Shares or by
a promissory note payable to the order of the Company which is acceptable to
the Committee, shall be made by the Participant for all shares so purchased.
Such payment may, with the consent of the Committee, in its Discretion, also
consist of a cash down payment and delivery of such a promissory note in the
amount of the unpaid exercise price. In the Discretion of, and subject to
such conditions as may be established by, the Committee, payment of the
option price may also be made by the Company retaining from the shares to be
delivered upon exercise of the stock option that number of shares having a
fair market value on the date of exercise equal to the option price of the
number of shares with respect to which the Participant exercises the option.
In the Discretion of the Committee, a Participant may exercise an option, if
then exercisable, in whole or in part, by delivery to the Company of written
notice of the exercise in such form as the Committee may prescribe,
accompanied by irrevocable instructions to a stock broker to promptly deliver
to the Company full payment for the shares with respect to which the option
is exercised from the proceeds of the stock broker's sale of or loan against
some or all of the shares. Such payment may also be made in such other manner
as the Committee determines is appropriate, in its Discretion. No Participant
shall have any of the rights of a shareholder of the Company under any option
until the actual issuance of shares to such Participant, and prior to such
issuance no adjustment shall be made for dividends, distributions or other
rights in respect of such shares, except as provided in Paragraphs 5 and 17.

        11. Automatic Stock Options: Notwithstanding other provisions of this
Plan and to the extent shares are available for grant under the Plan, Outside
Directors and SRC members shall automatically be granted Non-qualified Stock
Options on the terms described in this Paragraph 11.

        Each Outside Director of the Corporation shall automatically be
granted a Nonqualified Stock Option to purchase 5,000 shares of Common Stock
as of the date he or she is first elected or appointed to the Board of
Directors. Each Outside Director of the Corporation who is re-elected to the
Board of Directors shall automatically be granted a Nonqualified Stock Option
to purchase 2,000 shares of Common Stock as of the date of each re-election.

        Each person who is elected or appointed to serve as an SRC member
shall automatically be granted a Nonqualified Stock Option to purchase 2,500
shares of Common Stock as of the date of his or her election or appointment.
Each SRC member who is re-elected to the Scientific Review Council shall
automatically be granted a Nonqualified Stock Option to purchase 1,000 shares
of Common Stock as of the date of each re-election.

                                     -5-

<PAGE>

        All options granted under this Paragraph 11 shall be exercisable in
one-third cumulative annual installments beginning one year after the date of
grant, shall expire ten years after the date of grant and shall have an
option price equal to 100% of the fair market value of the Company's Common
Stock on the date of grant.

        12. Non-transferability of Options: No option granted under the Plan
to a Participant shall be transferable by such Participant otherwise than by
will or by the laws of descent and distribution, and each such option shall
be exercisable, during the lifetime of the Participant, only by the
Participant.

        13. Continuance of Employment; No Right to Continued Employment: The
Committee may require, in its Discretion, that any Participant under the Plan
to whom an option shall be granted shall agree in writing as a condition of
the granting of such option to remain in his or her position as an employee,
director, or SRC member of the Company or a Subsidiary for a designated
minimum period from the date of the granting of such option as shall be fixed
by the Committee.

        Nothing contained in the Plan or in any option granted pursuant to
the Plan, nor any action taken by the Committee hereunder, shall confer upon
any Participant any right with respect to continuation of employment, or
other service by or to the Company or a Subsidiary nor interfere in any way
with the right of the Company or a Subsidiary to terminate such person's
employment, or other service at any time.

        14. Termination of Employment; Expiration of Options: Subject to the
other provisions of the Plan, including, without limitation, Paragraphs 9,
and 17 and this Paragraph 14, all rights to exercise options shall terminate
when a Participant ceases to be an employee, director, or SRC member of the
Company or a Subsidiary for any cause, except that the Committee may, in its
Discretion, permit the exercise of all or any portion of the options granted
to such Participant

               (i) for a period not to exceed three months following such
        termination with respect to Incentive Options that are intended to
        remain Incentive Options if such termination is not due to death or
        permanent disability of the Participant,

               (ii) for a period not to exceed one year following termination
        of employment with respect to Incentive Options that are Intended to
        remain Incentive Options if termination of employment is due to the
        death or permanent disability of the Participant, and

               (iii) for a period not to extend beyond the expiration date
        with respect to Nonqualified Options or Incentive Options that are
        not intended to remain Incentive Options,

all subject to any restrictions, terms and conditions fixed by the Committee
either at the date of the award or at the date it exercises such Discretion.
In no event, however, shall an option be 

                                     -6-

<PAGE>

exercisable after its expiration date, and, unless the Committee in its
Discretion determines otherwise (pursuant to Paragraphs 9 or 17), an option
may only be exercised after termination of a Participant's employment or
other service by or to the Company to the extent exercisable on the date of
such termination or to the extent exercisable as a result of the reason for
such termination. The Committee may evidence the exercise of its Discretion
under this Paragraph 14 in any manner it deems appropriate, including by
resolution or by a provision in, or amendment to, the option.

        If not sooner terminated, each stock option granted under the Plan
shall expire not more than 10 years from the date of the granting thereof;
provided that with respect to an Incentive Option, such option shall expire
not more than 5 years after the date of granting thereof.

        15. Investment Purpose: If the Committee in its Discretion determines
that as a matter of law such procedure is or may be desirable, it may require
a Participant, upon any exercise of any option granted under the Plan or any
portion thereof and as a condition to the Company's obligation to deliver
certificates representing the shares subject to exercise, to execute and
deliver to the Company a written statement, in form satisfactory to the
Committee, representing and warranting that the Participant's purchase of
Common Shares upon exercise thereof shall be for such person's own account,
for investment and not with a view to the resale or distribution thereof and
that any subsequent sale or offer for sale of any such shares shall be made
either pursuant to (a) a Registration Statement on an appropriate form under
the Securities Act, which Registration Statement has become effective and is
current with respect to the shares being offered and sold, or (b) a specific
exemption from the registration requirements of the Securities Act, but in
claiming such exemption the Participant shall, prior to any offer for sale or
sale of such shares, obtain a favorable written opinion from counsel for or
approved by the Company as to the availability of such exemption. The Company
may endorse an appropriate legend referring to the foregoing restriction upon
the certificate or certificates representing any shares issued or transferred
to the Participant upon exercise of any option granted under the Plan.

        16. Withholding Payments: If upon the exercise of any Nonqualified
Option or a disqualifying disposition (within the meaning of Section 422 of
the Code) of shares acquired upon exercise of an Incentive Option, there
shall be payable by the Company or a Subsidiary any amount for income tax
withholding, in the Committee's Discretion, either the Participant shall pay
such amount to the Company, or the amount of Common Shares delivered by the
Company to the Participant shall be appropriately reduced, to reimburse the
Company or such Subsidiary for such payment. The Company or any of its
Subsidiaries shall have the right to withhold the amount of such taxes from
any other sums or property due or to become due from the Company or any of
its Subsidiaries to the Participant upon such terms and conditions as the
Committee shall prescribe. The Company may also defer issuance of the stock
upon exercise of such option until payment by the Participant to the Company
of the amount of any such tax. The Committee may, in its Discretion, permit
Participants to satisfy such withholding obligations, in whole or in part, by
electing to have the amount of Common Shares delivered or deliverable by the
Company upon exercise of a stock option appropriately reduced, or by electing
to tender Common Shares back to the Company subsequent to exercise of a stock
option to reimburse the Company or such 

                                     -7-

<PAGE>

Subsidiary for such income tax withholding, subject to such rules and
regulations, if any, as the Committee may adopt. The Committee may make such
other arrangements with respect to income tax withholding as it shall
determine.

        17. Extraordinary Transactions: In case the Company (i) consolidates
with or merges into any other corporation or other entity and is not the
continuing or surviving entity of such consolidation or merger, or (ii)
permits any other corporation or other entity to consolidate with or merge
into the Company and the Company is the continuing or surviving entity but,
in connection with such consolidation or merger, the Common Shares are
changed into or exchanged for stock or other securities of any other
corporation or other entity or cash or any other assets, or (iii) transfers
all or substantially all of its properties and assets to any other
corporation or other person or entity, or (iv) dissolves or liquidates, or
(v) effects a capital reorganization or reclassification in such a way that
holders of Common Shares shall be entitled to receive stock, securities, cash
or other assets with respect to or in exchange for the Common Shares, then,
and in each such case, proper provision shall be made so that, each
Participant holding a stock option upon the exercise of such option at any
time after the consummation of such consolidation, merger, transfer,
dissolution, liquidation, reorganization or reclassification (each
transaction, for purposes of this Paragraph 17, being herein called a
"Transaction"), shall be entitled to receive (at the aggregate option price
in effect for all Common Shares issuable upon such exercise immediately prior
to such consummation and as adjusted to the time of such Transaction), in
lieu of Common Shares issuable upon such exercise prior to such consummation,
the stock and other securities, cash and assets to which such Participant
would have been entitled upon such consummation if such Participant had so
exercised such stock option in full immediately prior thereto (subject to
adjustments subsequent to such Transaction provided for in Paragraph 5).

        Notwithstanding anything in the Plan to the contrary, in connection
with any Transaction and effective as of a date selected by the Committee,
which date shall, in the Committee's judgment, be far enough in advance of
the Transaction to permit Participants holding stock options to exercise
their options and participate in the Transaction as a holder of Common
Shares, the Committee, acting in its Discretion without the consent of any
Participant, may effect one or more of the following alternatives with
respect to all of the outstanding stock options (which alternatives may be
made conditional on the occurrence of the applicable Transaction and which
may, if permitted by law, vary among individual Participants): (a) accelerate
the time at which stock options then outstanding may be exercised so that
such stock options may be exercised in full for a limited period of time on
or before a specified date fixed by the Committee after which specified date
all unexercised stock options and all rights of Participants thereunder shall
terminate; (b) accelerate the time at which stock options then outstanding
may be exercised so that such stock options may be exercised in full for
their then remaining term; or (c) require the mandatory surrender to the
Company of outstanding stock options held by such Participants (irrespective
of whether such stock options are then exercisable) as of a date, before or
not later than sixty days after such Transaction, specified by the Committee,
and in such event the Company shall thereupon cancel such stock options and
shall pay to each Participant an amount of cash equal to the excess of the
fair market value of the aggregate Common Shares subject to such stock
option, determined as 

                                     -8-

<PAGE>

of the date such Transaction is effective, over the aggregate option price of
such shares, less any applicable withholding taxes; provided, however, the
Committee shall not select an alternative (unless consented to by the
Participant) such that, if a Participant exercised his or her accelerated
stock option pursuant to alternative (a) or (b) and participated in the
Transaction or received cash pursuant to alternative (c), the alternative
would result in the Participant's owing any money by virtue of the operation
of Section 16(b) of the Exchange Act. If all such alternatives have such a
result, the Committee shall, in its Discretion, take such action to put such
Participant in as close to the same position as such Participant would have
been in had alternative (a), (b) or (c) been selected but without resulting
in any payment by such Participant pursuant to Section 16(b) of the Exchange
Act. Notwithstanding the foregoing, with the consent of affected
Participants, each with respect to such Participant's option only, the
Committee may in lieu of the foregoing make such provision with respect to
any Transaction as it deems appropriate.

        18. Effectiveness of Plan: This Plan shall be effective on the date
the Board of Directors of the Company adopts this Plan, provided that the
shareholders of the Company approve the Plan within 12 months after its
adoption by the Board of Directors. Options may be granted before shareholder
approval of this Plan, but each such option shall be subject to shareholder
approval of this Plan. No option granted under this Plan shall be exercisable
unless and until this Plan shall have been approved by the Company's
shareholders.

        19. Termination, Duration and Amendments to the Plan: The Plan may be
abandoned or terminated at any time by the Board of Directors of the Company.
Unless sooner terminated, the Plan shall terminate on the date ten years
after the earlier of its adoption by the Board of Directors or its approval
by the shareholders of the Company, and no stock options may be granted under
the Plan thereafter. The termination of the Plan shall not affect the
validity of any option which is outstanding on the date of termination.

        For the purpose of conforming to any changes in applicable law or
governmental regulations, or for any other lawful purpose, the Board of
Directors shall have the right, with or without approval of the shareholders
of the Company, to amend or revise the terms of this Plan or any option
agreement under this Plan at any time; provided, however, that (i) to the
extent required by Section 162(m) of the Code and related regulations, or any
successor rule, but only with respect to amendments or revisions affecting
Participants whose compensation is subject to Section 162(m) of the Code, and
to the extent required by Section 422 of the Code, or any successor section,
but only with respect to Incentive Options, no such amendment or revision
shall increase the maximum number of shares in the aggregate which are
subject to this Plan (subject, however, to the provisions of Paragraphs 5 and
17) without the approval or ratification of the shareholders of the Company,
and (ii) no such amendment or revision shall change the option price (except
as contemplated by Paragraphs 5 and 17) or alter or impair any option which
shall have been previously granted under this Plan, in a manner adverse to a
Participant, without the consent of such Participant.

        As adopted by the Board of Directors on August 14, 1997.

           (b) Additional Rents. Operating Expenses. In addition to the base
           rent set forth above, Lessee further agrees to pay as Additional
           Rental Lessee's pro rata share of all Operating Expenses of the
           Building, it being understood that the base rent payable by Lessee
           to Lessor is the absolute net rent to be received by Lessor and
           there shall be no charges or impositions against said rent. Lessor
           may, within nine (9) months following the close of any calendar
           year for which additional rental is due under this Paragraph,
           invoice Lessee for its pro rata share of operating expenses. The
           invoice shall include in reasonable detail the computations of the
           additional rental, and Lessee agrees to make payment of the
           additional rental to Lessor within thirty (30) days following
           receipt of the invoice. In addition to Lessor's right to invoice
           Lessee for actual operating expenses, if any, at the end of each
           calendar year, Lessor shall have the right but not the obligation,
           at any time during the term of this Lease, to estimate operating
           expenses for the coming calendar year (or remaining part thereof)
           and invoice Lessee for its pro rata share of such estimated
           operating expenses. Lessee shall pay monthly, concurrent with each
           Base Rent payment due hereunder, an amount equal to one-twelfth
           (1/12) the estimated annual operating expenses, such payment being
           considered "Additional Rent". In the event of an overpayment or
           underpayment by Lessee, each party hereby agrees to an appropriate
           adjustment to be paid or credited, as the case may be, as
           determined by the accounting of actual operating expenses as
           provided herein, to the Additional Rent payment next becoming due
           from Lessee. Such adjustment shall be made within thirty (30) days
           after Lessor has finally determined


                                      2


<PAGE>

           the actual operating expenses for the calendar year and notified
           Lessee of the payment (or credit) which is due. Appropriate
           proration shall be made for partial periods. Lessee shall have the
           right, at any time within sixty (60) days from receipt of Lessor's
           notice of the actual Additional Rent due hereunder, and at
           Lessee's own expense and at a reasonable time, to inspect Lessor's
           books at the Lessor or its agent's place of business, relevant to
           the Additional Rent due under this Paragraph, or at Lessor's
           option, Lessor shall provide to Lessee a statement of operating
           expenses in reasonable detail. In the event that Lessee shall
           dispute the Additional Rent due hereunder (including election by
           Lessee to inspect Lessor's books, as provided for above), Lessee
           shall nonetheless be required to pay the Additional Rent so
           invoiced to Lessee as and when required herein pending resolution
           of such dispute. Lessee's obligation to pay this rent shall
           survive the termination of the Lease.

                     For the purposes of this Lease, the term "Operating
           Expenses" shall mean any and all costs and expenses paid,
           incurred, or accrued by Lessor, or its agents, for any calendar
           year or portion of a calendar year, in connection with the
           operation, management, servicing, maintenance, and repair of all
           Common Areas and of the Building of which the Premises are a part,
           as determined and stated in accordance with generally accepted
           accounting principles; and, further, shall include all insurance
           premiums Lessor is required to pay hereunder, sewer and water
           charges, and real property taxes and installments of special
           assessments, but shall exclude: provisions for depreciation;
           interest on indebtedness, leasing commissions, and income taxes;
           dividends; and other expenses which do not relate to the operation
           of the Building.

                     The term "Common Areas", as used in this Lease, shall
           mean the portions of the Property provided and maintained by
           Lessor for the common use and benefit of Lessor and occupants of
           the Property, generally, and the employees, invitees, and
           licensees of Lessor and such occupants. Lessee's proportionate
           share of Lessor's expenses described above shall be determined by
           multiplying the amount of such operating and maintenance costs by
           a factor, the numerator of which shall be the Net Rentable Area of
           the Premises (as stated in Section 1 of this Lease) and the
           denominator of which shall be the Net Rentable Area of the
           Building of which the Premises are a part. For the purposes of
           this Lease, this factor shall be .10.

           (c) Sales Tax. Lessee shall also pay, along with all rentals due
           under this Lease, an amount equal to any tax on the rentals now or
           hereafter imposed by any lawful authority.

           (d) Payment Conditions. Except as herein expressly provided to the
           contrary in this Lease, all rent payments due under this Lease
           shall be payable in legal tender of the United States of America
           on the first day of each month during the


                                      3


<PAGE>

           term of this Lease, in advance, without set-off or deduction.

           Other remedies for nonpayment of rent notwithstanding, if the
           monthly rental payment is not received by Lessor on or before the
           tenth day of the month for which rent is due, or if any other
           payment due Lessor by Lessee is not received by Lessor on or
           before the tenth day of the month next following the month in
           which Lessee was invoiced, a service charge of five percent (5%)
           of such past due amounts shall become due and payable in addition
           to such other amounts owed under this Lease.

4. ASSIGNMENT AND SUBLETTING. Lessee shall not assign, mortgage, pledge, or
encumber this Lease, or permit all or any part of the Premises to be
subleased without the prior written consent of Lessor and Lessor's mortgagee,
if any, which consent shall not be unreasonably withheld or delayed. Any
transfer of this Lease by merger, consolidation, reorganization, or
liquidation of Lessee, or by operation of law, or change in ownership of or
power to vote the majority of the outstanding voting stock of a corporate
Lessee, or by change in ownership of a controlling partnership interest in a
partnership Lessee, shall constitute an assignment for the purposes of this
paragraph. Notwithstanding the foregoing, Lessee shall have the right to
assign or sublease part or all of the Premises to any of its subsidiaries,
affiliates or any parent corporation of Lessee with prior written notice to
Lessor, provided that: (i) Lessee continues to be primarily liable on its
obligations as set forth herein; (ii) any such assignee or sublessee shall
assume and be bound by all covenants and obligations of Lessee herewith;
(iii) the proposed assignee or sublessee is, in Lessor's good faith
judgement, compatible with other tenants in the Building and seeks to use the
Premises only for the Permitted Lessee and for a use that is not prohibited
under the terms of a lease with another tenant in the Building; and (iv) such
use would not result in a material change in the number of personnel working
in, or members of the general public visiting, the Premises.

           In addition to other reasonable bases, Lessee hereby agrees that
Lessor shall be deemed to be reasonable in withholding its consent, if: (a)
such proposed assignment or sublease is for a term less than the whole of the
remaining Lease term; or (b) Lessee is in default under any of the terms,
covenants, conditions, provisions and agreements of this lease at the time of
request for consent or on the effective date of such subletting or
assignment; or (c) the proposed subtenant or assignee is, in Lessor's good
faith judgement, incompatible with other tenants in the Building, or seeks to
use any portion of the Premises for a use not consistent with other uses in
the Building, or is financially incapable of assuming the obligations of this
Lease; or (d) the proposed assignee or sublessee or its business is subject
to compliance with additional requirements of the law (including related
regulation) commonly known as the "Americans With Disabilities Act" beyond
those requirements which are applicable to the Lessee, unless the proposed
assignee or sublessee shall (i) first deliver plans and specifications for
complying with such additional requirements and obtain Lessor's consent
thereto, and (ii) comply with all Lessor's conditions for or contained in
such consent, including without limitation, requirements for security to
assure the lien-free completion of such improvements by and at the sole cost
and expense of Lessee or its sublessee or assignee. Lessee shall submit to
Lessor the name of the proposed assignee 


                                      4


<PAGE>

or subtenant, the terms of the proposed assignment or subletting, the nature
of the proposed subtenant's or assignee's business and such information as to
the assignee's or subtenant's financial responsibility and general reputation
as Lessor may reasonably require.

           No subletting or assignment, even with the consent of Lessor,
shall relieve Lessee of its primary obligation to pay the Rent and to perform
all of the other obligations to be performed by Lessee hereunder. The
acceptance of Rent by Lessor from any other person or entity shall not be
deemed to be a waiver by Lessor of any provision of this Lease or to be a
consent to any assignment, subletting or other transfer, or a novation.
Consent to one assignment, subletting or other transfer shall not be deemed
to constitute consent to any subsequent assignment, subletting or transfer.

           In lieu of giving any consent to a sublease or an assignment of
all the Premises, Lessor may, at Lessor's option, elect to terminate this
Lease. In the case of a proposed subletting of a portion of the Premises,
Lessor may, at Lessor's option, elect to terminate the Lease with respect to
that portion of the Premises being proposed for subletting. The effective
date of any such termination shall be thirty (30) days after the proposed
effective date of any proposed assignment or subletting.

           One-half of any proceeds in excess of Lessee's Base Rent and
Lessee's pro rata share of operating expenses which is received by Lessee
pursuant to an assignment or subletting consented to by Lessor, less
reasonable brokerage commissions actually paid by Lessee, and less other
reasonable costs incurred by Lessee in connection with making the space
available for lease, shall be remitted to Lessor as additional Rent within
ten (10) days of receipt by Lessee. For purposes of this Paragraph, all money
or value in whatever form received by Lessee from or on account of any party
as consideration for an assignment or subletting shall be deemed to be
proceeds received by Lessee pursuant to an assignment or subletting.

5. USE. Lessee covenants that during the term of this Lease, the Premises
shall be used and occupied only as a general office for medical research,
product development, and production and for no other purpose or purposes
without the prior written consent of Landlord. Lessee agrees to cause the
Premises to be operated for such use during the entire term of this Lease,
unless prevented from doing so by causes beyond Lessee's control, and to
conduct its business at all times in a reputable manner. In no event shall
Lessee conduct its business in any manner that would be objectionable or
unsuitable for the general business reputation and standards of the Property
or in conflict with the restrictions of record from time to time affecting
the Property, and Lessor shall have the authority to prescribe such
additional rules (or to modify or rescind rules in existence from time to
time) governing the conduct of business on the Property, as Lessor, in its
sole discretion, shall deem necessary to insure that such standards are
observed.


6. CARE OF PREMISES. Lessee shall not perform any acts or carry on any
practices 


                                      5


<PAGE>

which may injure the Premises or be a nuisance or menace to other occupants
of the Property. Lessee shall keep the Premises clean and free from rubbish,
vermin and dirt at all times, and shall store all trash and garbage within
the Premises and arrange for the regular pickup of such trash and garbage at
Lessee's expense. Lessee shall not burn any trash or garbage of any kind in
or about the Premises.

           Lessee shall not keep, store, or display any items or inventory on
or otherwise obstruct the exterior area adjacent to the Premises without the
written consent of Lessor. Lessee shall not use, or permit the use of, any
portion of the Premises for any unlawful purpose or purposes. Lessee shall
not make any structural changes in the Premises without Lessor's prior
written consent, which consent shall be subject to such conditions as Lessor,
in its sole discretion, may impose.

7. MAINTENANCE. Lessor shall maintain the foundation, outer walls, and roof
of the Building in good condition and repair, except that Landlord shall not
be required to make any repairs occasioned by the negligent act or omission
of Lessee or Lessee's agents or employees. Lessee shall make all repairs and
replacements to the Premises not expressly assumed by Lessor under this
Lease, and shall keep all portions of the Premises, including, without
limitation, the interior of the Premises and the wiring and plumbing systems
and conduits, exterior doors, windows and window frames, in good order,
condition, and repair during the entire term of this Lease, and shall also
keep the Premises in a clean, sanitary, and safe condition in accordance with
Law and in accordance with all directives, rules, and regulations of
governmental agencies having jurisdiction over the Premises or Lessee's use
thereof.

           Notwithstanding anything contained herein to the contrary, Lessee
shall, at its sole cost and expense, maintain and keep the heating,
ventilating and air conditioning systems, apparatus and equipment (the "HVAC
Systems") in good condition and repair during the entire term of this Lease.
Within thirty (30) days of the date Lessee takes possession of the Premises,
Lessee shall enter into a maintenance contract, requiring at least bimonthly
service with a reputable and licensed full service HVAC maintenance firm, for
the routine maintenance and servicing of the HVAC Systems. Lessee shall
furnish Lessor with a copy of the then current maintenance contract. Lessor
shall have the specific right to annually inspect, or have inspected, the
HVAC equipment, and if in Lessor's reasonable judgment such equipment is not
being properly maintained, Lessor shall have the right to give notice to
Lessee of such, and Lessor may, at the expense of the Lessee, undertake to
make such repairs as are necessary to put the HVAC equipment in good
condition.

8. ALTERATIONS AND IMPROVEMENTS. Lessee shall not make, or allow to be made,
any alterations or physical additions in or to the leased Premises without
first obtaining the written consent of Lessor. Any alterations, physical
additions, or improvements to the leased Premises made by Lessee shall at
once become the property of Lessor and shall be surrendered to Lessor upon
the termination of this Lease. Lessor, at its option, may require Lessee to
remove any physical additions and/or repair any alterations in order to
restore the leased Premises to the condition existing prior to the time
Lessee took possession, all costs of such removal and/or alterations to be
borne by Lessee. This clause shall not apply to movable equipment or
furniture 


                                      6


<PAGE>

owned by Lessee which may be removed by Lessee at the end of the term of this
Lease if Lessee is not then in default and if such equipment and furniture is
not then subject to any other rights, liens, and interests of Lessor.

9. UTILITIES. Lessee agrees to pay promptly, before delinquency, all charges
for electricity, telephone, janitorial services, and for all other utilities
and services supplied to the Premises, whether determined by meter or
otherwise. If such charges are not so paid, they shall be added to the next
or any subsequent month's rent thereafter to become due, if Lessor elects,
and be collectable as rent.

10. ASSUMPTION OF RISK-INDEMNITY-LIABILITY INSURANCE. Lessor shall not be
liable to Lessee or Lessee's customers, licensees, agents, invitees, or
employees, or to any other person on the Premises for any injury or damages
to its, his, or their persons or property by any cause whatsoever, including,
but not limited to, acts or omissions of any other occupant of the Property,
construction defects, water, rain, stoppage, or leaks of gas, or other defect
in, on, or about the Premises, unless such injury is due to Lessor's
negligence. Lessee covenants and agrees to indemnify and save Lessor harmless
from and against any and all claims for damage or injuries to Property and/or
for any personal injury or loss of life in, upon, or about the Premises or on
the Common Areas immediately adjacent to the Premises, arising for any reason
whatsoever during the term of this Lease, except such as may be the result of
the negligence or continuing default of Lessor, or Lessor's agents,
employees, or contractors.

           Lessee covenants and agrees to provide on or before the
Commencement Date and keep in force during the term of this Lease, a
commercial liability policy of insurance, insuring Lessor and Lessee (and
naming them both in the policy) against any liability whatsoever occasioned
by accident on or about the Premises, or any appurtenances thereto. Such
policy shall be written by a good and solvent insurance company in the amount
of One Million Dollars ($1,000,000.00) combined single limit coverage. The
original policy or a certificate thereof, together with evidence of payment
therefor, shall be delivered to Lessor at least ten (10) days prior to the
Commencement Date. Lessee shall renew such policy not less than thirty (30)
days prior to its Expiration Date, from time to time, and furnish such
renewals and evidence of payment therefor to Lessor. Such policy or
certificates shall contain a provision that the insurer will not cancel the
policy without giving Lessor ten (10) days' written notice.

11. CASUALTY INSURANCE. Lessor shall, at all times during the term of this
Lease, maintain a policy or policies of insurance issued by a reputable
insurance company, insuring the Building against loss or damage by fire,
explosion, or other hazards and contingencies for the full insurable value
thereof; provided, that Lessor shall not be obligated to insure any
furniture, equipment, machinery, goods, or supplies not covered by this Lease
which Lessee may bring or obtain upon the leased Premises, or any additional
improvements which Lessee may construct thereon. If the annual premiums
charged Lessor for such casualty insurance exceed the standard premium rates
because the nature of Lessee's operation results in extrahazardous exposure,
then Lessee shall, upon receipt of appropriate premium invoices, reimburse
Lessor for such increases 


                                      7


<PAGE>

in such premiums.

12. LESSOR'S RIGHT OF ENTRY. Lessor shall have the right, at all reasonable
hours, to enter the leased Premises for the following reasons: inspection,
cleaning, or making repairs, making alterations or additions, as Lessor may
deem necessary or desirable; determining Lessee's use of the leased Premises,
or determining if an act of default under this Lease has occurred.

13. RIGHTS OF MORTGAGEE. Lessee accepts this Lease subject and subordinate to
any recorded mortgage, deed of trust and other lien presently existing upon
the leased Premises. Lessor is hereby irrevocably vested with full power and
authority to subordinate Lessee's interest under this Lease to any mortgage,
deed of trust, or other lien hereafter placed on the leased Premises, and
Lessee agrees, upon demand, to execute additional instruments subordinating
this Lease as Lessor may require. If the interests of Lessor under this Lease
shall be transferred by reason of foreclosure or other proceedings for
enforcement of any mortgage on the leased Premises, Lessee shall be bound to
the transferee (sometimes called the "Purchaser") under the terms, covenants,
and conditions of this Lease for the balance of the terms remaining, and any
extensions or renewals, with the same force and effect as if the Purchaser
were Lessor under this Lease, and Lessee agrees to attorn to the Purchaser,
including the mortgagee under any such mortgage, if it be the Purchaser, as
its Lessor, the attornment to be effective and self-operative without the
execution of any further instruments upon the Purchaser succeeding to the
interest of Lessor under this Lease. The respective rights and obligations of
Lessee and the Purchaser, upon the attornment, to the extent of the then
remaining balance of the term of this Lease, and any extensions or renewals,
shall be and are the same as those set forth in this Lease. In the event that
Lessor shall default in the performance of the terms and provisions of this
Lease, Lessee hereby agrees to give Lessor's Mortgagee, by registered mail, a
copy of any notice of default served upon the Lessor, provided that prior to
such notice Lessee has been notified in writing, (by way of notice of
Assignment of Rents and Leases, or otherwise) of the address of such
Mortgagee. Lessee further agrees that if Lessor shall have failed to cure
such default within the time provided for in this Lease, then the Mortgagee
shall have an additional sixty (60) days within which to cure such default,
or, if such default cannot be cured within that time, then such additional
time is may be necessary to cure such default provided said Mortgagee has
commenced and is diligently pursuing the remedies necessary to cure such
default (including, but not limited to commencement of foreclosure
proceedings, if necessary to effect such cure). Lessee hereby agrees that it
shall not terminate this Lease while such remedies are being so diligently
pursued by Lessor's Mortgagee.

14. ESTOPPEL CERTIFICATES. Lessee agrees to furnish promptly, from time to
time, upon request of Lessor or Lessor's mortgagee, a statement certifying
that Lessee is in possession of the Premises; the Premises are acceptable;
the Lease is in force and effect; the Lease is unmodified; Lessee claims no
present charge, lien, or claim of offset against rent; the rent is paid for
the current month, but is not paid and will not be paid for more than one
month in advance; there is no existing default by reason of some act or
omission by Lessor; and such other matters as may be reasonably required by
Lessor or Lessor's mortgagee or assignee.


                                      8


<PAGE>

15. QUIET ENJOYMENT. Lessor warrants that it has full right to execute and to
perform this Lease and to grant the estate demised, and that Lessee, upon
payment of the required rents and performing the terms, conditions,
covenants, and agreements contained in this Lease, shall peaceably and
quietly have, hold, and enjoy the leased Premises during the full term of
this Lease, as well as any extension or renewal thereof.

16. COMPLIANCE WITH LAW. Lessee shall comply with all laws, ordinances,
orders, rules, and regulations (State, Federal, Municipal, and other agencies
or bodies having any jurisdiction thereof) relating to the use, condition, or
occupancy of the leased Premises.

17. HOLDING OVER. In the event of holding over by Lessee, after the
expiration or termination of this Lease, such hold over shall be as a tenant
at will, and all terms and provisions of this Lease shall be applicable
during such period, except that Lessee shall pay Lessor, as rental for the
period of such hold over, an amount equal to twice the rent which would have
been payable by Lessee had such hold over period been a part of the original
term of this Lease, and Lessee will vacate said Premises and deliver the same
to Lessor upon Lessee's receipt of notice from Lessor to vacate said
Premises. The rental payable during such hold over period shall be payable to
Lessor on demand. No holding over by Lessee, whether with or without consent
of Lessor, shall operate to extend this Lease except as herein provided.

18. CONDEMNATION. If the whole or any part of the Premises shall be taken by
any public authority under the power of eminent domain, or be conveyed by
deed in lieu of condemnation, then the term of this Lease shall cease on the
part so taken from the day possession of the portion of the Premises so taken
is required by the condemning authority. If the part so taken shall destroy
the usefulness of the Premises for Lessee's business purposes, then Lessee
shall have the right either to terminate this Lease as of such date or to
continue in the possession of the remainder of the Premises under the terms
herein provided, except that the then current monthly Base Rent shall be
reduced in proportion to the amount of the Premises taken. If Lessee shall
fail to terminate this Lease within thirty (30) days after its receipt of
notice of the taking, Lessee's failure shall be regarded as a waiver of its
right to cancel, whereupon this Lease shall continue for the then balance of
the term. If Lessee exercises its right to cancel, all advance rent paid by
Lessee shall be adjusted to the date of termination. If Lessee fails to
exercise its right to cancel, Lessor shall, at its own cost and expense (but
only to the extent of the condemnation proceeds paid to Lessor as
compensation for the portion of the Premises so taken), make repairs made
necessary due to the partial taking.

           The parties agree that, except as expressly noted in the preceding
paragraph, Lessee shall not be entitled to any damages or compensation by
reason of the taking of its leasehold or any portion thereof, and Lessor
shall be entitled to all compensation paid by the condemning authority.

19. DAMAGES OR DESTRUCTION. In the event the Premises are damaged by fire,
explosion, or other casualty, Lessor shall commence the repair, restoration,
or rebuilding thereof, 



                                      9


<PAGE>

within ninety (90) days of such damage, after first notifying the Lessee
within thirty (30) days of such intent. If the casualty or the repair,
restoration, or rebuilding caused thereby shall render the Premises
untenantable, in whole or in part, an equitable abatement in rent shall be
allowed from the date when the damage occurred until the date when the
Premises are again fit for occupancy by Lessee. If such a fire, explosion, or
other casualty damages the building in which the Premises are located to the
extent of fifty percent (50%) or more thereof, Lessor may, in lieu of
repairing, restoring, or rebuilding the same, terminate this Lease within
sixty (60) days after occurrence of the event causing the damage. In such
event, the obligation of Lessee to pay rent and other charges hereunder,
shall end as the date when the occupancy ceased. In the event Lessor's fire
and extended coverage insurance provides for a "deductible" and a loss occurs
which is the kind of risk otherwise insured under the policy, and such loss
is the result of the Lessee's or its agents, employees, or contractors
negligence, act or omission, then Lessee shall pay to Lessor, promptly upon
being billed therefor the lesser of the (a) the amount of the loss or (b) the
amount of the deductible.

20. EVENTS OF DEFAULT. The following events shall be deemed to be events of
default by Lessee under this Lease:

           (a) Lessee shall fail to pay any installment of the rent herein
           reserved when due, or any other payment or reimbursement to Lessor
           required herein when due.

           (b) Lessee shall become insolvent, or shall make a transfer in
           fraud of creditors, or shall make an assignment for the benefit of
           creditors;

           (c) Lessee shall file a petition under any section or chapter of
           the National Bankruptcy Act, as amended, or under any similar Law
           or Statute of the United States or any State thereof, or Lessee
           shall be adjudged bankrupt or insolvent in proceedings filed
           against Lessee thereunder;

           (d) A receiver or trustee shall be appointed for all or
           substantially all of the assets of Lessee;

           (e) Lessee shall desert or vacate any substantial portion of the
           Premises;

           (f) Lessee shall fail to comply with any term, provision, or
           covenant of this Lease (including the rules and regulations of the
           Building), other than the foregoing in this Section 20, and shall
           not cure such failure within thirty (30) days after written notice
           thereof to Lessee; or

           (g) There shall occur, during any twelve-month period during the
           term of this Lease, more than two events of default, as specified
           in subsections (a) through (e) above regardless of whether such
           defaults have been cured by Lessee within the allowed grace
           periods.


                                     10


<PAGE>

21. REMEDIES. Upon the occurrence of any such events of default described in
Section 20 hereof, Lessor shall have the option to pursue any one or more of
the following remedies without notice or demand whatsoever:

           (a) Terminate this Lease, in which event Lessee shall immediately
           surrender the Premises to Lessor, and if Lessee fails to do so,
           Lessor may, without prejudice to any other remedy which it may
           have for possession or arrearages in rent, enter upon and take
           possession of the Premises, and expel or remove Lessee and any
           other person who may be occupying such Premises or any part
           thereof, without being liable for prosecution or any claim of
           damages therefor; and Lessee agrees to pay to Lessor, on demand,
           the amount of all loss and damage which Landlord may suffer by
           reason of such termination, whether through inability to relet the
           Premises on satisfactory terms or otherwise;

           (b) Enter upon and take possession of the Premises and expel or
           remove Lessee and any other person who may be occupying such
           Premises or any part thereof, without being liable for prosecution
           or any claim for damages therefor, and relet the Premises and
           receive the rent therefor; and Lessee agrees to pay to the Lessor,
           on demand, any deficiency that may arise by reason of such
           reletting, including without limitation, costs incurred for space
           planning, rent concessions, remodeling and tenant improvements,
           advertising, and leasing commissions. In the event Lessor is
           successful in reletting the Premises at a rental in excess of that
           agreed to be paid by Lessee, pursuant to the terms of this Lease,
           Lessor and Lessee each mutually agree that Lessee shall not be
           entitled, under any circumstances, to such excess rental, and
           Lessee does hereby specifically waive any claim to such excess
           rental;

           (c) Enter upon the Premises without being liable for prosecution
           or any claim for damages therefor, and do whatever Lessee is
           obligated to do under the terms of this Lease; and Lessee agrees
           to reimburse Lessor, on demand, for any expenses which Lessor may
           incur in thus effecting compliance with Lessee's obligations under
           this Lease; and Lessee further agrees that Lessor shall not be
           liable for any damages resulting to the Lessee from such action,
           whether caused by the negligence of Lessor or otherwise;

           (d) Lessee covenants and agrees that Lessee will pay, in addition
           to the rentals and other sums agreed to be paid hereunder, all
           sums and expenses incurred by Lessor in enforcing, defending, or
           interpreting Lessor's rights under this Lease, including without
           limitation, all court costs, all attorneys' fees (whether incurred
           out of court, in the trail court, on appeal, or in bankruptcy
           proceedings), and all collection costs and fees charged by third
           parties in connection with Lessor's enforcement of Lessor's rights
           hereunder.


                                     11


<PAGE>

22. WAIVER OF DEFAULT OR REMEDY. Failure of Lessor to declare an event of
default, immediately upon its occurrence or delay in taking any action in
connection with an event of default, shall not constitute a waiver of the
default, but Lessor shall have the right to declare the default at any time
and take such action as is lawful or authorized under this Lease. Pursuit of
any one or more of the remedies set forth in Paragraph 21 above shall not
preclude pursuit of any one or more of the other remedies provided elsewhere
in this Lease or provided by Law, nor shall pursuit of any remedy provided
constitute a forfeiture or waiver of any rent or damages accruing to Lessor
by reason of the violation of any of the terms, provisions, or covenants of
this Lease. Failure by Lessor to enforce one or more of the remedies provided
upon an event of default shall not be deemed or construed to constitute a
waiver of the default or of any other violation or breach of any of the
terms, provisions, and covenants contained in this Lease.

23. Intentionally omitted.

24. SECURITY DEPOSIT. Lessee, contemporaneously, with the execution of this
Lease, has deposited with Lessor the sum of Two Thousand Six Hundred Eighteen
and 50/00 Dollars ($2,618.50), receipt of which is hereby acknowledged by
Lessor as security for the full and faithful performance by Lessee of all the
terms, covenants, and conditions of this Lease upon Lessee's part to be
performed, which sum shall be returned to Lessee after the time fixed as the
expiration of the term hereof, provided Lessee has fully and faithfully
carried out all of the terms, covenants, and conditions on Lessee's part to
be performed. Lessor shall have the right, but not the obligation, to apply
any part of the deposit to cure any default of Lessee, and if Lessor does so,
Lessee shall, upon demand, deposit with Lessor the amount so applied so that
Lessor shall have the full deposit on hand at all times during the term of
this Lease. Lessee's failure to pay to Lessor a sufficient amount to restore
the security deposit to the original sum deposited, within five (5) days
after receipt of demand therefor, shall constitute a default under this
Lease. No interest shall be paid by Lessor to Lessee on such security
deposit. Should Lessee comply with all of the terms, covenants, and
conditions of this Lease and promptly pay all of the rent due hereunder, as
it falls due, and all other sums payable by Lessee to Lessor hereunder, the
deposit shall be returned in full to tenant at the end of the term of this
Lease or at the earliest termination of this Lease.

           In the event of a sale of the Premises or the Property, Lessor
shall have the right to transfer the security deposit to the vendee, and
Lessor shall be released from all further liability for the return of such
security deposit. Lessee agrees to look solely to the new Lessor for the
return of the security deposit. The provisions of this Paragraph shall apply
to every transfer or assignment made of the security deposit to a new Lessor.
The security deposit under this Lease shall not be mortgaged, assigned, or
encumbered by the Lessee without the written consent of Lessor and may be
commingled with other funds of Lessor.

25. SURRENDER. Upon the termination of this Lease, whether by forfeiture,
lapse of time, or otherwise, or upon the termination of Lessee's right to
possession of the Premises, Lessee will,



                                     12

at once, surrender and deliver up the Premises, together with all
improvements thereon, to Lessor in good condition and repair, ordinary wear
and tear accepted. Said improvements shall include all plumbing, lighting,
electrical, heating, cooling and ventilating fixtures and equipment, and
other articles of personal property used in the operation of the Premises (as
distinguished from operations, incident to the business of Lessee, articles
of personal property incident to Lessee's business are hereinafter referred
to as "Trade Fixtures"). All additional hardware, non-Trade Fixtures, and all
improvements, temporary or permanent, in or upon the premises placed there by
Lessee, shall become Lessor's property and shall remain upon the Premises
upon such termination of this Lease by lapse of time or otherwise, without
compensation or allowance or credit to Lessee, unless Lessor requests their
removal in writing at or before the time of such termination of this Lease.
If Lessor so requests removal of said additions, hardware, non-Trade
Fixtures, and improvements, and Lessee does not make such removal at said
termination of this Lease, or within ten (10) days after such request,
whichever is later, Lessor may remove and deliver the same to any other place
of business of Lessee or warehouse the same, and Lessee shall pay the cost of
such removal, delivery, and warehousing to Lessor on demand. Lessee may
remove Trade Fixtures upon the termination of this Lease provided, however,
that Lessee shall repair any injury or damage to the Premises which may
result from such removals.

26. RELOCATION. In the event Lessor determines, at its sole discretion, to
utilize the Premises for other purposes during the term of this Lease, Lessee
hereby agrees to promptly relocate to other space in the Building or to
another building in the Breckenridge Park controlled by Lessor or its
affiliate so designated by Lessor, provided such other space is of comparable
size as the Premises and is approved by Lessee in its sole reasonable
judgement, which approval must be granted or withheld in writing within ten
(10) days of receipt of notice to Lessee, failing which Lessee's approval of
this relocation shall be deemed granted. Lessor shall pay all out-of-pocket
expenses of any such relocation, including the expenses of reprinting
stationery, moving and reconstruction of all Lessee furnished and Lessor
furnished improvements. In the event of such relocation, this Lease shall
continue in full force and effect without any change in the terms or other
conditions, but with the new location substituted for the old location as set
forth in Paragraph 1 of this Lease.

27. SIGNS. Lessee, at Lessee's cost and expense, shall have the right to
install and maintain a sign on the Premises, subject to the previous written
approval of Lessor as to dimensions, materials, location and design, and
subject to such standards as Lessor shall establish for all signs on the
Property. Lessor shall provide, at the Lessee's expense, the metal base, upon
which the aforementioned sign shall be affixed.

28. LESSOR'S LIMITED LIABILITY. The liability of Lessor to Lessee for any
default by Lessor under the terms of this Lease shall be expressly limited to
the interest of Lessor in the Premises and the Property, and Lessee agrees to
look solely to Lessor's interest in the Premises and Property for the
recovery of any judgment or deficiency. Lessee hereby acknowledges and agrees
that Lessor shall have no personal liability for the default of its
obligations under this Lease.

29. LIENS AND ENCUMBRANCES. Lessee shall have no authority, express or
implied, to create or place any lien or encumbrance of any kind or nature
whatsoever upon, or in any manner to bind, the interest of Lessor in the
Premises or to charge the rentals payable hereunder for any claim in favor of
any person dealing with Lessee, including those who may furnish materials or
perform labor for any construction or repairs, and each such claim shall
affect and each such lien shall attach to, if at all, only the leasehold
interest granted to Lessee by this instrument.

           Lessee covenants and agrees that it will pay, or cause to be paid,
all sums legally due and payable by it on account of any labor performed or
materials furnished in connection with any work performed on the Premises on
which any lien is, or can be validly and legally asserted against its
leasehold interest in the Premises, or the improvements thereon, and that it
will save and hold Lessor harmless from any and all loss, cost, or expense
based on or arising out of asserted claims or liens against the leasehold
estate or against the right, title, and interest of the Lessor in the
Premises under the terms of this Lease.

30. INTEREST. Monies owed by one party to the other shall, after due date,
bear interest at the maximum legal rate.

<PAGE>

this Paragraph 39. Lessee will be solely responsible for and will defend,

against any and all claims, costs, and liabilities, including attorneys fees
and costs, arising out of or in connection with the removal, cleanup, and

hazardous substances, including without limitation substances defined as
"Hazardous Substances" in the Comprehensive Environmental Response

40. RADON DISCLOSURE. Radon is a naturally occurring radioactive gas that,

health risks to persons who are exposed to it. Levels of radon that exceed
federal and state guidelines have been found in structures in the State of
Florida. Additional information regarding radon and radon testing may be
acquired from the county Public Health Unit. Lessor makes no representations
to Lessee concerning the presence or absence of radon gas in the Premises or
the Building at any time or in any quantity. By executing this Lease, Lessee
expressly releases Lessor from any loss, claim, liability or damage now or
hereafter arising from or relating to the presence at any time of such
substances in the Premises or the Building.

41. TENANT IMPROVEMENTS. Lessor hereby accepts the Premises in its "as is"
condition, it being understood that Lessor shall not be required to provide
any additional improvements or alterations to the Premises.

42. PARKING. During the term of this Lease, Lessee shall have the
nonexclusive use in common with Lessor, other tenants of the Building, their
guests and invitees, of the unreserved common automobile parking areas,
driveways, and footways, subject to rules and regulations for the use thereof
as prescribed from time to time by Lessor. Lessor shall have the right to
reserve parking spaces as it elects and condition use thereof on such terms
as it elects.

43. THIS LEASE is contingent upon Lessee accepting and executing this Lease
Agreement by no later than August 20, 1998, or this Lease shall be null and
void.

                  any other right or remedy. No waiver or indulgence by the
                  Bank of any default shall be effective unless in writing
                  and signed by the Bank, nor shall a waiver on one occasion
                  be construed as a bar to or waiver of that right on any

           12.3   This agreement, the Notes, and any related loan documents
                  embody the entire agreement and understanding between the

                  and understandings relating to their subject matter. If any
                  one or more of the obligations of the Borrower under this
                  agreement or the Notes shall be invalid, illegal or
                  unenforceable in any jurisdiction, the validity, legality
                  and enforceability of the remaining obligations of the
                  Borrower shall not in any way be affected or impaired, and
                  such validity, illegality or unenforceability in one
                  jurisdiction shall not affect the validity, legality or
                  enforceability of the obligations of the Borrower under
                  this agreement or the Notes in any other jurisdiction.

           12.4   The Borrower, if more than one, shall be jointly and

Agreement until December 1, 1999 (the "Corporate Acquisition Revolving Loan
Termination Date"), up to an aggregate principal amount outstanding at any
time not to exceed the lesser of Seven Million Five Hundred Thousand Dollars
($7,500,000) (the "Corporate Acquisition Loan Commitment Amount"); provided
that each date in which a disbursement is made (a "Disbursement Date") under
this Letter Agreement must be a Business Day (as defined in the Corporate

               1.4. Other Borrower Obligations. All loans, advances,

guarantees and liabilities whatsoever of the Borrower to the Bank, whether

or hereafter arising shall be included in the term "Loans."






<PAGE>

               1.5. The Notes. The Working Capital Loans shall be evidenced
by a promissory note in the form of Exhibit A attached hereto and made a part
hereof (the "Working Capital Note"). The Corporate Acquisition Revolving
Loans shall be evidenced by a promissory note in the form of Exhibit B
attached hereto and made a part hereof (the "Corporate Acquisition Revolving
Note"). The Working Capital Note and the Corporate Acquisition Revolving Note
are referred to as the "Notes".

               1.6. Interest. The principal balance from time to time
outstanding under the Notes shall bear interest as set forth in the Notes.

               1.7. Payments. The principal and accrued interest of the Notes
shall be payable as set forth in the Notes.

        2.     CONDITIONS AND BORROWING PROCEDURES

               2.1. Conditions. As a condition precedent to the Loans, the
Borrower agrees to furnish to the Bank, prior to the Borrowing hereunder, in
form satisfactory to the Bank the executed Letter Agreement and the Notes.

               2.2.   Borrowing Procedures.

                      2.2.1.  Notice. The Borrower shall give the Bank notice
        of the Borrower's desire for a Loan as set forth in the Notes.

                      2.2.2.  Bank Obligations. The Bank agrees to make the
        Loans on the Disbursement Date established by notice to the Bank from
        the Borrower conforming to the requirements of Section 2.2.1 by
        crediting the deposit account of the Borrower with the Bank in the
        amount of such Loan; provided, however, that the Bank shall not be
        obligated if:

                             2.2.2.1.  Any of the conditions precedent set
              forth in Section 2.1 of this Letter Agreement shall not have
              been satisfied or waived by the Bank, or

                             2.2.2.2.  Such proposed Loan would cause the
              aggregate unpaid principal amount of the Loans outstanding
              under an applicable Note to exceed the Commitment Amount under
              that Note, on a Disbursement Date.

        3.     REPRESENTATIONS AND WARRANTIES

        The Borrower represents and warrants and such representations and
warranties shall be deemed to be continuing representations and warranties
during the entire life of this Letter Agreement:

               3.1. Corporate Existence and Power. The Borrower is a
corporation duly organized and existing in good standing under the laws of
the State of Michigan; the Borrower is in good standing in each jurisdiction
in which it is required to be qualified to do business; execution, delivery
and performance of this Letter Agreement and other documents and instruments
required under this Letter Agreement, and the issuance of the Notes by the
Borrower are within its corporate powers, have been duly authorized, are not
in contravention of law or the terms of the Borrower's Articles of
Incorporation or Bylaws, and do not require the consent or approval of any
governmental body, agency or authority; and this Letter Agreement and other
documents and instruments required under this Letter Agreement and the Notes,
when issued and delivered, will be valid and binding in accordance with their
terms.



                                     -2-


<PAGE>


               3.2. Authorization and Approvals. The execution, delivery and
performance of this Letter Agreement and any other documents and instruments
required under this Letter Agreement, and the issuance of the Notes by the
Borrower are not in contravention of the unwaived terms of any indenture,
agreement or undertaking to which the Borrower is a party or by which it is
bound.

               3.3. Actions, Suits or Proceedings. No litigation or other
proceeding before any court or administrative agency is pending, or to the
knowledge of the officers of the Borrower is threatened against the Borrower,
the outcome of which could materially impair the Borrower's financial
condition or the ability of the Borrower to carry on its business.

               3.4. Financial Statements. The financial statements of the
Borrower previously furnished Bank are, to the best of the Borrower's
knowledge, complete and correct and fairly present the financial condition of
the Borrower; since said date there has been no material adverse change in
the financial condition of the Borrower; the Borrower does not have any
material contingent obligations (including any liability for taxes) not
disclosed by or reserved against in said financial statements and at the
present time there are no material unrealized or anticipated losses from any
present commitment of the Borrower.

               3.5. Taxes. All tax returns and tax reports of the Borrower
required by law to be filed have been duly filed or extensions obtained, and
all taxes, assessments and other governmental charges or levies (other than
those presently payable without penalty and those currently being contested
in good faith for which adequate reserves have been established) upon the
Borrower (or any of its properties) which are due and payable have been paid.
The charges, accruals and reserves on the books of the Borrower in respect of
the Federal income tax for all periods are adequate in the opinion of the
Borrower.

               3.6. Compliance with Laws. The Borrower is, in the conduct of
its business, in compliance in all material respects with all federal, state
or local laws, statutes, ordinances and regulations applicable to it, the
enforcement of which, if the Borrower were not in compliance, would
materially adversely affect its business or the value of its property or
assets. The Borrower has all approvals, authorizations, consents, licenses,
orders and other permits of all governmental agencies and authorities,
whether federal, state or local, required to permit the operation of its
business as presently conducted, except such approvals, authorizations,
consents, licenses, orders and other permits with respect to which the
failure to have can be cured without having a material adverse effect on the
operation of such business.

               3.7. No Representation. No representation or warranty by the
Borrower in this Letter Agreement, nor any statement or certificate
(including financial statements) furnished or to be furnished to Bank
pursuant hereto contains or will contain any materially untrue statement of
any material fact or omits or will omit to state a material fact necessary to
make such representation, warranty, statement or certificate not misleading;
provided, however, as to any financial statements of the Sellers, this
representation and warranty is made based solely on the best knowledge of the
Borrower.

               3.8. Environmental Laws. The Borrower is not a party to any
litigation or administrative proceeding, nor so far as is known by the
Borrower is any litigation or administrative proceeding threatened against
the Borrower, which in either case (a) asserts or alleges that the Borrower
violated any applicable environmental laws ("Environmental Laws"), (b)
asserts or alleges that the Borrower is required to clean up, remove, or take
remedial or other response action due to the disposal, depositing, discharge,
leaking or other release of any hazardous substances or materials, (c)
asserts or alleges that the Borrower is required to pay all or a portion of
the cost of any past, present, or future 


                                     -3-


<PAGE>

cleanup, removal or remedial or other response action which arises out of or
is related to the disposal, depositing, discharge, leaking or other release
of any hazardous substances or materials by the Borrower. To the best
knowledge of the Borrower, there are no conditions existing currently which
would subject the Borrower to damages, penalties, injunction relief or
cleanup costs under any applicable Environmental Laws or which require or are
likely to require cleanup, removal, remedial action or other response
pursuant to applicable Environmental Laws by the Borrower. The Borrower is
not subject to any judgment, decree, order or citation related to or arising
out of applicable Environmental Laws and to the best knowledge of the
Borrower, the Borrower has not been named or listed as a potentially
responsible party by any governmental body or agency in a matter arising
under any applicable Environmental Laws. The Borrower has all permits,
licenses and approvals required under applicable Environmental Laws.

                                               TAX I.D. NO.: 38-______________

$1,500,000                                                   Lansing, Michigan

                                                              March ____, 1998


        FOR VALUE RECEIVED, the undersigned promises to pay to the order of
COMERICA BANK (the "Bank") at any office of the Bank, on Demand, the
principal sum or so much of the principal sum of One Million Five Hundred
Thousand Dollars ($1,500,000) as may from time to time have been advanced and
be outstanding under that certain Letter Agreement dated March ____, 1998,
between the undersigned and the Bank (the "Letter Agreement") plus all
accrued but unpaid interest thereon.

        This Note is a Master Note under which sums may or must be repaid
from time to time and under which new advances are to be made by the Bank
pursuant to the terms and conditions of the Letter Agreement, and the books
and records of the Bank shall constitute the best evidence of the amount of
indebtedness at any time owing hereunder.

        The entire indebtedness outstanding hereunder from time to time shall
bear interest at the Applicable Interest Rate, as elected by Borrower from
time to time, or as otherwise determined under the terms and conditions of
this Note. Interest shall be payable on the first day of each month
commencing April 1, 1998, and on the last day of any Applicable Interest
Period (each an "Interest Payment Date").

        Interest accruing at the Prime Rate shall be computed on the basis of
a 360 day year and shall be assessed for the actual number of days elapsed,
and in such computation, effect shall be given to any change in the Prime
Rate as a result of any change in the Prime Rate on the date of each such
change.

        Interest accruing at the Eurodollar Rate shall be computed on the
basis of a 360 day year and shall be assessed for the actual number of days
elapsed from the first day of the Applicable Interest Period applicable
thereto, but not including the last day thereof.

        The amount from time to time outstanding under this Note, the
Applicable Interest Rate, the Applicable Interest Period, and the amount and
date of any repayment shall be noted on Bank's books and records, which shall
be conclusive evidence thereof, absent manifest error; provided, however, any
failure by Bank to make any such notation, or any error in any such notation,
shall not relieve Borrower of its obligations to repay Bank all principal,
all accrued and unpaid interest thereon, and all other amounts payable by
Borrower to Bank under or pursuant to this Note in accordance with the terms
hereof.

        Interest Rate Election. The Borrower may elect to have the Applicable
Interest Rate be the Eurodollar Rate by giving the Bank verbal notice (a
"Notice of Interest Rate Election") of each such election not later than 1:00
p.m. Lansing, Michigan time two (2) Business Days before each Eurodollar Rate
Loan is to be made, specifying:

               (a) the date when such election shall be effective (which
shall be a Business Day);



                                     A-1

<PAGE>


               (b)    the Specified Principal;

               (c)    the Applicable Interest Rate; and

               (d)    the Applicable Interest Period.

        If the Borrower fails to make such election, the Applicable Interest
Rate shall be the Prime Rate.

        Subsequent Elections as to Borrowing. The Borrower may elect to (a)
continue a Eurodollar Rate Loan or a portion thereof, as a Eurodollar Rate
Loan, or (b) convert a Eurodollar Rate Loan or a portion thereof, to a Prime
Rate Loan, or (c) elect to convert a Prime Rate Loan, or a portion thereof,
to a Eurodollar Rate Loan, in each case by giving verbal notice thereof to
the Bank not later than 1:00 p.m. Lansing time (i) two (2) Business Days
prior to the date any such continuation of or conversion to a Eurodollar Rate
Loan is to be effective and (ii) one (1) Business Day prior to the date any
such continuation of or conversion to a Prime Rate Loan to be effective,
provided that an outstanding Eurodollar Rate Loan may only be converted on
the last day of the Applicable Interest Period with respect thereto, and
provided further, if a continuation of a Loan, or a conversion of a Loan to,
a Eurodollar Rate Loan is requested, such notice shall also specify the
Applicable Interest Period for such continuation or conversion. If the
Borrower shall not timely deliver a Notice of Interest Rate Election with
respect to an outstanding Eurodollar Rate Loan, the Borrower shall be deemed
to have elected to convert such Eurodollar Rate Loan to a Prime Rate Loan on
the last day of the then current Applicable Interest Period. If requested by
the Bank, the Borrower shall confirm any verbal notice hereunder in writing.

        Maximum Amount of Loans. The sum of the aggregate principal amount of
all Loans shall not at any time exceed the Working Capital Loan Commitment
Amount.

        Limitations of Requests and Elections. Notwithstanding any other
provision of this Note to the contrary, if, upon receiving a request for a
Eurodollar Rate Loan, a request for a continuation of a Eurodollar Rate Loan
as a Eurodollar Rate Loan or a request for a conversion to a Eurodollar Rate
Loan, (a) deposits in dollars for periods comparable to the Eurodollar
Interest Period elected by the Borrower are not available to the Bank in the
relevant interbank secondary market, or (b) the Eurodollar Rate will not
adequately and fairly reflect the cost to the Bank of making, funding or
maintaining the related Eurodollar Rate Loan, or (c) by reason of national or
international financial, political or economic conditions or by reason of any
applicable law, treaty, rule or regulation (whether domestic or foreign) now
or hereafter in effect, or the interpretation or administration thereof by
any governmental authority charged with the interpretation or administration
thereof, or compliance by the Bank with any guideline, request or directive
of such authority (whether or not having the force of law), including without
limitation exchange controls, it is impracticable, unlawful or impossible for
the Bank (i) to make or fund Eurodollar Rate Loans or (ii) to maintain
outstanding such Eurodollar Rate Loan, or (iii) to convert a Loan to a
Eurodollar Rate Loan, then the Borrower shall not be entitled, so long as
such circumstances continue, to request a Eurodollar Rate Loan or a
continuation of or conversion to a Eurodollar Rate Loan. In the event that
such circumstances no longer exist, the Bank shall again consider requests
for Eurodollar Rate Loans, and requests for continuations of and conversions
to Eurodollar Rate Loans.

        Maximum Amount of Interest Rate Elections. Except for (a) Borrowings
and conversions thereof which exhaust the entire remaining amount of the
Working Capital Loan Commitment, and (b) payments required pursuant hereto,
each Borrowing and each continuation or conversion thereof and each repayment
thereof shall be in a minimum amount of Five Hundred Thousand Dollars
($500,000.00) and in integral 


                                     A-2


<PAGE>

multiples of One Hundred Thousand Dollars ($100,000.00). No more than three
(3) Eurodollar Interest Periods shall be permitted to exist at any one time.

        Optional Prepayments of Principal. The Borrower may, at any time,
upon notice to the Bank, pay all or part of the Loan outstanding bearing
interest at the Prime Rate without penalty, premium or other charge. The
Borrower may not prepay any portion of the Loan as to which an election for,
a continuation of or a conversion to a Eurodollar Rate is pending, and any
Eurodollar Rate Loan may only be paid on the last day of the Applicable
Interest Period with respect thereto, unless, in addition to any other
amounts required to be paid, the Borrower also pays the Bank the Prepayment
Amount. All notices of prepayment that are delivered to the Bank by the
Borrower pursuant to this section shall be delivered by 1:00 p.m. Lansing
time on the relevant Business Day or if delivered at a later time shall be
deemed to have been delivered as of the next Business Day. A notice of
prepayment with respect to a Eurodollar Rate Loan shall not be revocable by
the Borrower after delivery to the Bank.

        Mandatory Payments of Loans. The Borrower shall pay to the Bank, the
amount, if any, by which the aggregate unpaid principal amount of all Loans
from time to time exceeds the Working Capital Commitment Amount, together
with all interest accrued and unpaid on the amount of such excess. Such
payment shall be immediately due and owing without notice or demand upon the
occurrence of any such excess. Mandatory payments under this Section shall be
applied first to Prime Rate Loans.

         Interest Payments. The Borrower shall pay interest to the Bank on
the unpaid principal amount of the Loan, for the period commencing on the
date hereof until the Loan is paid in full, on each Interest Payment Date and
at maturity (whether at stated maturity, by demand, by acceleration or
otherwise), and thereafter on demand, at the Applicable Interest Rate.
Notwithstanding the foregoing, the Borrower shall pay interest on demand at
the Overdue Rate on the outstanding principal amount of the Loan and any
other amount payable by the Borrower hereunder (other than interest) which is
not paid in full when due (whether at stated maturity, by demand, by
acceleration or otherwise) for the period commencing on the due date thereof
until the same is paid in full.

        No Set Off or Deduction. All payments of principal and interest and
other amounts payable by the Borrower hereunder shall be made by the Borrower
without set off or counterclaim, and free and clear of, and without deduction
or with holding for, or on account of, any present or future taxes, levies,
imposts, duties, fees, assessments, or other charges of whatever nature,
imposed by any governmental authority, or by any department, agency or other
political subdivision or taxing authority.

        Additional Costs. (a) In the event that the adoption of, or any
change in or in the interpretation by any governmental authority of, any
applicable law, treaty, rule or regulation (whether domestic or foreign), or
compliance by the Bank with any guideline, request or directive of any
governmental authority that is promulgated, made, issued, or changed (whether
or not having the force of law), shall (i) change the basis of taxation of
payments to the Bank of any amounts payable by the Borrower under this Note
(other than taxes imposed on the overall net income of the Bank), or (ii)
shall impose, modify or deemed applicable any reserve, special deposit or
similar requirement against assets of, deposits with or for the account of,
or credit extended by the Bank, or (iii) shall impose any other condition
with respect hereto, and the result of any of the foregoing is to increase
the cost to the Bank, of making, funding or maintaining any Eurodollar Rate
Loan or to reduce the amount of any sum receivable by the Bank, thereon, then
the Borrower shall pay to the Bank from time to time, upon request by the
Bank, additional amounts sufficient to compensate the Bank, for such
increased cost or reduced sum receivable to the extent, in the case of any
Eurodollar Rate Loan, the Bank is not compensated therefor in the computation
of the interest rate applicable to such Eurodollar Rate Loan or pursuant to
subsection (b) of this Section. A statement as to 


                                     A-3


<PAGE>

the amount of such increased cost or reduced sum receivable and reason
therefor, prepared in good faith and in reasonable detail by the Bank, and
submitted by the Bank, to the Borrower, shall be conclusive and binding for
all purposes absent material error.

               (b) In the event that any applicable law, rule, regulation, or
guideline now in effect relating to capital adequacy, or that the adoption
of, or any change in or in the interpretation by any governmental authority
of any applicable law, treaty, rule or regulation (whether domestic or
foreign), or that compliance by the Bank with any guideline, request or
directive of any governmental authority (whether or not having the force of
law) relating to capital adequacy, or that is promulgated, made, issued, or
changed including any risk-based capital guidelines, affects or would affect
the amount of capital required or expected to be maintained by the Bank (or
any corporation controlling the Bank) and the Bank determines that the amount
of such capital required or expected to be maintained is increased by or
based upon the existence of the Bank's obligations hereunder and such
increase has the effect of reducing the rate of return on the Bank's (or such
controlling corporation's) capital as a consequence of such obligations
hereunder to a level below that which the Bank (or such controlling
corporation) could have achieved but for such circumstances (taking into
consideration its policies with respect to capital adequacy) by an amount
deemed by the Bank to be material, then the Borrower shall pay to the Bank,
from time to time, upon request by the Bank additional amounts sufficient to
compensate the Bank (or such controlling corporation) for any increase in the
amount of capital and reduced rate of return which the Bank reasonably
determines to be allocable to the existence of the Bank's obligations
hereunder. A statement as to the amount of such compensation and reason
therefor, prepared in good faith and in reasonable detail by the Bank, as the
case maybe, and submitted by the Bank to the Borrower, shall be conclusive
and binding for all purposes absent material error.

        Illegality and Impossibility. In the event that the adoption of, or
any change in or in the interpretation by any governmental authority of, any
applicable law, treaty, rule or regulation (whether domestic or foreign), or
compliance by the Bank with any guideline, request or directive of any
governmental authority that is promulgated, made, issued, or changed (whether
or not having the force of law), including without limitation exchange
controls, shall make it unlawful or impossible for the Bank to maintain any
Eurodollar Rate Loan under this Note, the Borrower shall upon receipt of
notice thereof from the Bank, repay in full the then outstanding principal
amount of each Eurodollar Rate Loan so affected, together with all accrued
interest thereon to the date of payment, (a) on the last day of the then
current Eurodollar Interest Period applicable to such Loan if the Bank may
lawfully continue to maintain such Loan to such day, or (b) immediately if
the Bank may not continue to maintain such Loan to such day.

        Funding Losses. If the Borrower makes any payment of principal on a
Eurodollar Rate Loan on any day other than the last day of the Applicable
Interest Period, or if the Borrower fails to make any payment of principal or
interest in respect of a Eurodollar Rate Loan when due, the Borrower shall,
in addition to any amounts that may be payable pursuant hereto, pay to the
Bank the Prepayment Amount on demand. A statement as to the Prepayment Amount
as of the Prepayment Date, prepared in good faith and in reasonable detail by
the Bank and submitted by the Bank to the Borrower, shall be conclusive and
binding for all purposes in the absence of material error.

        Regulation D Compensation. If the Eurocurrency liabilities (as
defined in and pursuant to Regulation D of the Board of Governors of the
Federal Reserve System, as amended or modified from time to time) of the Bank
is a positive number, the Bank may require the Borrower to pay to the extent
not already provided for in the definition of Eurodollar Rate,
contemporaneously with each payment of interest on the Eurodollar Rate Loans,
additional interest on the related Eurodollar Rate Loan of the Bank at a rate
per annum equal to the excess of (a)(i) the applicable Eurodollar Rate
expressed as a decimal, divided by


                                     A-4


<PAGE>


(ii) one minus the maximum rate (expressed as a decimal) at which the Bank is
required to maintain reserves on Eurocurrency liabilities or, if such
regulation or definition is modified, and as long as the Bank is required to
maintain reserves against a category of liabilities which includes deposits
in Dollars or includes a category of assets which includes loans in Dollars,
the rate at which such reserves are required to be maintained on such
category, over (b) the rate specified in clause (a)(i). If the Bank wishes to
require payment of such additional interest, it shall so notify the Borrower
of such requirement either on or before the Effective Date or at least three
(3) Business Days prior to the first Eurodollar Interest Period to which such
requirement shall apply, which notice shall indicate the place where such
additional interest shall be payable to the Bank. In the event the Bank shall
have given notice to the Borrower pursuant to the foregoing sentence,
thereafter the Borrower shall pay to the Bank at the place indicated in such
notice the additional interest due under this paragraph on all Eurodollar
Rate Loans made by the Bank thereafter, until the Bank notifies the Borrower
that it no longer wishes to require the payment of the additional interest
under this paragraph, and all such additional interest shall be payable on
the Interest Payment Date with respect thereto.

        If an Event of Default (as defined in the Letter Agreement) occurs

Agreement, the Bank may exercise any one or more of the rights and remedies
granted by the Letter Agreement or any document contemplated thereby or given
to a secured party under applicable law, including without limit the right to

of the Bank.

        In the event that and so long as any Event of Default shall have
occurred and be continuing, the indebtedness outstanding under this Note
shall bear interest at the Overdue Rate.

        The Undersigned and all accommodation parties, guarantors and
indorsers (i) waive presentment, demand, protest and notice of dishonor, (ii)
agree that no extension or indulgence to the undersigned or release or
non-enforcement of any security, whether with or without notice, shall affect

$7,500,000                                                   Lansing, Michigan

                                                              March ____, 1998


        FOR VALUE RECEIVED, the undersigned promises to pay to the order of
COMERICA BANK (the "Bank") at any office of the Bank, on the Termination
Date, the principal sum or so much of the principal sum of Seven Million Five
Hundred Thousand Dollars ($7,500,000) as may from time to time have been
advanced and be outstanding under that certain Letter Agreement dated March
____, 1998, between the undersigned and the Bank (the "Letter Agreement")
plus all accrued but unpaid interest thereon.

        This Note is a Master Note under which sums may or must be repaid
from time to time and under which new advances are to be made by the Bank
pursuant to the terms and conditions of the Letter Agreement, and the books
and records of the Bank shall constitute the best evidence of the amount of
indebtedness at any time owing hereunder.

        The entire indebtedness outstanding hereunder from time to time shall
bear interest at the Applicable Interest Rate, as elected by Borrower from
time to time, or as otherwise determined under the terms and conditions of
this Note. Interest shall be payable on the first day of each month
commencing April 1, 1998, and on the last day of any Applicable Interest
Period (each an "Interest Payment Date").

        Interest accruing at the Prime Rate shall be computed on the basis of
a 360 day year and shall be assessed for the actual number of days elapsed,
and in such computation, effect shall be given to any change in the Prime
Rate as a result of any change in the Prime Rate on the date of each such
change.

        Interest accruing at the Eurodollar Rate shall be computed on the
basis of a 360 day year and shall be assessed for the actual number of days
elapsed from the first day of the Applicable Interest Period applicable
thereto, but not including the last day thereof.

        The amount from time to time outstanding under this Note, the
Applicable Interest Rate, the Applicable Interest Period, and the amount and
date of any repayment shall be noted on Bank's books and records, which shall
be conclusive evidence thereof, absent manifest error; provided, however, any
failure by Bank to make any such notation, or any error in any such notation,
shall not relieve Borrower of its obligations to repay Bank all principal,
all accrued and unpaid interest thereon, and all other amounts payable by
Borrower to Bank under or pursuant to this Note in accordance with the terms
hereof.

        Interest Rate Election. The Borrower may elect to have the Applicable
Interest Rate be the Eurodollar Rate by giving the Bank verbal notice (a
"Notice of Interest Rate Election") of each such election not later than 1:00
p.m. Lansing, Michigan time two (2) Business Days before each Eurodollar Rate
Loan is to be made, specifying:



                                     B-1


<PAGE>

               (a) the date when such election shall be effective (which
                   shall be a Business Day);

               (b) the Specified Principal;

               (c) the Applicable Interest Rate; and

               (d) the Applicable Interest Period.

        If the Borrower fails to make such election, the Applicable Interest
Rate shall be the Prime Rate.

        Subsequent Elections as to Borrowing. The Borrower may elect to (a)
continue a Eurodollar Rate Loan or a portion thereof, as a Eurodollar Rate
Loan, or (b) convert a Eurodollar Rate Loan or a portion thereof, to a Prime
Rate Loan, or (c) elect to convert a Prime Rate Loan, or a portion thereof,
to a Eurodollar Rate Loan, in each case by giving verbal notice thereof to
the Bank not later than 1:00 p.m. Lansing time (i) two (2) Business Days
prior to the date any such continuation of or conversion to a Eurodollar Rate
Loan is to be effective and (ii) one (1) Business Day prior to the date any
such continuation of or conversion to a Prime Rate Loan to be effective,
provided that an outstanding Eurodollar Rate Loan may only be converted on
the last day of the Applicable Interest Period with respect thereto, and
provided further, if a continuation of a Loan, or a conversion of a Loan to,
a Eurodollar Rate Loan is requested, such notice shall also specify the
Applicable Interest Period for such continuation or conversion. If the
Borrower shall not timely deliver a Notice of Interest Rate Election with
respect to an outstanding Eurodollar Rate Loan, the Borrower shall be deemed
to have elected to convert such Eurodollar Rate Loan to a Prime Rate Loan on
the last day of the then current Applicable Interest Period. If requested by
the Bank, the Borrower shall confirm any verbal notice hereunder in writing.

        Maximum Amount of Revolving Loans. The sum of the aggregate principal
amount of all Revolving Loans shall not at any time exceed the Corporate
Acquisition Loan Commitment Amount.

        Limitations of Requests and Elections. Notwithstanding any other
provision of this Note to the contrary, if, upon receiving a request for a
Eurodollar Rate Loan, a request for a continuation of a Eurodollar Rate Loan
as a Eurodollar Rate Loan or a request for a conversion to a Eurodollar Rate
Loan, (a) deposits in dollars for periods comparable to the Eurodollar
Interest Period elected by the Borrower are not available to the Bank in the
relevant interbank secondary market, or (b) the Eurodollar Rate will not
adequately and fairly reflect the cost to the Bank of making, funding or
maintaining the related Eurodollar Rate Loan, or (c) by reason of national or
international financial, political or economic conditions or by reason of any
applicable law, treaty, rule or regulation (whether domestic or foreign) now
or hereafter in effect, or the interpretation or administration thereof by
any governmental authority charged with the interpretation or administration
thereof, or compliance by the Bank with any guideline, request or directive
of such authority (whether or not having the force of law), including without
limitation exchange controls, it is impracticable, unlawful or impossible for
the Bank (i) to make or fund Eurodollar Rate Loans or (ii) to maintain
outstanding such Eurodollar Rate Loan, or (iii) to convert a Loan to a
Eurodollar Rate Loan, then the Borrower shall not be entitled, so long as
such circumstances continue, to request a Eurodollar Rate Loan or a
continuation of or conversion to a Eurodollar Rate Loan. In the event that
such circumstances no longer exist, the Bank shall again consider requests
for Eurodollar Rate Loans, and requests for continuations of and conversions
to Eurodollar Rate Loans.

        Maximum Amount of Interest Rate Elections. Except for (a) Borrowings
and conversions thereof which exhaust the entire remaining amount of the
Corporate Acquisition Revolving Loan Commitment, 


                                     B-2


<PAGE>
and (b) payments required pursuant hereto, each Borrowing and each
continuation or conversion thereof and each repayment thereof shall be in a
minimum amount of Five Hundred Thousand Dollars ($500,000.00) and in integral
multiples of One Hundred Thousand Dollars ($100,000.00). No more than three
(3) Eurodollar Interest Periods shall be permitted to exist at any one time.

        Optional Prepayments of Principal. The Borrower may, at any time,
upon notice to the Bank, pay all or part of the Loan outstanding bearing
interest at the Prime Rate without penalty, premium or other charge. The
Borrower may not prepay any portion of the Loan as to which an election for,
a continuation of or a conversion to a Eurodollar Rate is pending, and any
Eurodollar Rate Loan may only be paid on the last day of the Applicable
Interest Period with respect thereto, unless, in addition to any other
amounts required to be paid, the Borrower also pays the Bank the Prepayment
Amount. All notices of prepayment that are delivered to the Bank by the
Borrower pursuant to this section shall be delivered by 1:00 p.m. Lansing
time on the relevant Business Day or if delivered at a later time shall be
deemed to have been delivered as of the next Business Day. A notice of
prepayment with respect to a Eurodollar Rate Loan shall not be revocable by
the Borrower after delivery to the Bank.

        Mandatory Payments of Revolving Loans. The Borrower shall pay to the
Bank, the amount, if any, by which the aggregate unpaid principal amount of
all Revolving Loans from time to time exceeds the Corporate Acquisition Loan
Commitment Amount, together with all interest accrued and unpaid on the
amount of such excess. Such payment shall be immediately due and owing
without notice or demand upon the occurrence of any such excess. Mandatory
payments under this Section shall be applied first to Prime Rate Loans.

         Interest Payments. The Borrower shall pay interest to the Bank on
the unpaid principal amount of the Loan, for the period commencing on the
date hereof until the Loan is paid in full, on each Interest Payment Date and
at maturity (whether at stated maturity, by demand, by acceleration or
otherwise), and thereafter on demand, at the Applicable Interest Rate.
Notwithstanding the foregoing, the Borrower shall pay interest on demand at
the Overdue Rate on the outstanding principal amount of the Loan and any
other amount payable by the Borrower hereunder (other than interest) which is
not paid in full when due (whether at stated maturity, by demand, by
acceleration or otherwise) for the period commencing on the due date thereof
until the same is paid in full.

        No Set Off or Deduction. All payments of principal and interest and
other amounts payable by the Borrower hereunder shall be made by the Borrower
without set off or counterclaim, and free and clear of, and without deduction
or with holding for, or on account of, any present or future taxes, levies,
imposts, duties, fees, assessments, or other charges of whatever nature,
imposed by any governmental authority, or by any department, agency or other
political subdivision or taxing authority.

        Additional Costs. (a) In the event that the adoption of, or any
change in or in the interpretation by any governmental authority of, any
applicable law, treaty, rule or regulation (whether domestic or foreign), or
compliance by the Bank with any guideline, request or directive of any
governmental authority that is promulgated, made, issued, or changed (whether
or not having the force of law), shall (i) change the basis of taxation of
payments to the Bank of any amounts payable by the Borrower under this Note
(other than taxes imposed on the overall net income of the Bank), or (ii)
shall impose, modify or deemed applicable any reserve, special deposit or
similar requirement against assets of, deposits with or for the account of,
or credit extended by the Bank, or (iii) shall impose any other condition
with respect hereto, and the result of any of the foregoing is to increase
the cost to the Bank, of making, funding or maintaining any Eurodollar Rate
Loan or to reduce the amount of any sum receivable by the Bank, thereon, then
the Borrower shall pay to the Bank from time to time, upon request by the
Bank, additional amounts sufficient to compensate the Bank, for such
increased cost or reduced sum receivable to the extent, in the case of any



                                     B-3


<PAGE>

Eurodollar Rate Loan, the Bank is not compensated therefor in the computation
of the interest rate applicable to such Eurodollar Rate Loan or pursuant to
subsection (b) of this Section. A statement as to the amount of such
increased cost or reduced sum receivable and reason therefor, prepared in
good faith and in reasonable detail by the Bank, and submitted by the Bank,
to the Borrower, shall be conclusive and binding for all purposes absent
material error.

               (b) In the event that any applicable law, rule, regulation, or
guideline now in effect relating to capital adequacy, or that the adoption
of, or any change in or in the interpretation by any governmental authority
of any applicable law, treaty, rule or regulation (whether domestic or
foreign), or that compliance by the Bank with any guideline, request or
directive of any governmental authority (whether or not having the force of
law) relating to capital adequacy, or that is promulgated, made, issued, or
changed including any risk-based capital guidelines, affects or would affect
the amount of capital required or expected to be maintained by the Bank (or
any corporation controlling the Bank) and the Bank determines that the amount
of such capital required or expected to be maintained is increased by or
based upon the existence of the Bank's obligations hereunder and such
increase has the effect of reducing the rate of return on the Bank's (or such
controlling corporation's) capital as a consequence of such obligations
hereunder to a level below that which the Bank (or such controlling
corporation) could have achieved but for such circumstances (taking into
consideration its policies with respect to capital adequacy) by an amount
deemed by the Bank to be material, then the Borrower shall pay to the Bank,
from time to time, upon request by the Bank additional amounts sufficient to
compensate the Bank (or such controlling corporation) for any increase in the
amount of capital and reduced rate of return which the Bank reasonably
determines to be allocable to the existence of the Bank's obligations
hereunder. A statement as to the amount of such compensation and reason
therefor, prepared in good faith and in reasonable detail by the Bank, as the
case maybe, and submitted by the Bank to the Borrower, shall be conclusive
and binding for all purposes absent material error.

        Illegality and Impossibility. In the event that the adoption of, or
any change in or in the interpretation by any governmental authority of, any
applicable law, treaty, rule or regulation (whether domestic or foreign), or
compliance by the Bank with any guideline, request or directive of any
governmental authority that is promulgated, made, issued, or changed (whether
or not having the force of law), including without limitation exchange
controls, shall make it unlawful or impossible for the Bank to maintain any
Eurodollar Rate Loan under this Note, the Borrower shall upon receipt of
notice thereof from the Bank, repay in full the then outstanding principal
amount of each Eurodollar Rate Loan so affected, together with all accrued
interest thereon to the date of payment, (a) on the last day of the then
current Eurodollar Interest Period applicable to such Loan if the Bank may
lawfully continue to maintain such Loan to such day, or (b) immediately if
the Bank may not continue to maintain such Loan to such day.

        Funding Losses. If the Borrower makes any payment of principal on a
Eurodollar Rate Loan on any day other than the last day of the Applicable
Interest Period, or if the Borrower fails to make any payment of principal or
interest in respect of a Eurodollar Rate Loan when due, the Borrower shall,
in addition to any amounts that may be payable pursuant hereto, pay to the
Bank the Prepayment Amount on demand. A statement as to the Prepayment Amount
as of the Prepayment Date, prepared in good faith and in reasonable detail by
the Bank and submitted by the Bank to the Borrower, shall be conclusive and
binding for all purposes in the absence of material error.

        Regulation D Compensation. If the Eurocurrency liabilities (as
defined in and pursuant to Regulation D of the Board of Governors of the
Federal Reserve System, as amended or modified from time to time) of the Bank
is a positive number, the Bank may require the Borrower to pay to the extent
not already provided for in the definition of Eurodollar Rate,
contemporaneously with each payment of interest



                                     B-4


<PAGE>

on the Eurodollar Rate Loans, additional interest on the related Eurodollar
Rate Loan of the Bank at a rate per annum equal to the excess of (a)(i) the
applicable Eurodollar Rate expressed as a decimal, divided by (ii) one minus
the maximum rate (expressed as a decimal) at which the Bank is required to
maintain reserves on Eurocurrency liabilities or, if such regulation or
definition is modified, and as long as the Bank is required to maintain
reserves against a category of liabilities which includes deposits in Dollars
or includes a category of assets which includes loans in Dollars, the rate at
which such reserves are required to be maintained on such category, over (b)
the rate specified in clause (a)(i). If the Bank wishes to require payment of
such additional interest, it shall so notify the Borrower of such requirement
either on or before the Effective Date or at least three (3) Business Days
prior to the first Eurodollar Interest Period to which such requirement shall
apply, which notice shall indicate the place where such additional interest
shall be payable to the Bank. In the event the Bank shall have given notice
to the Borrower pursuant to the foregoing sentence, thereafter the Borrower
shall pay to the Bank at the place indicated in such notice the additional
interest due under this paragraph on all Eurodollar Rate Loans made by the
Bank thereafter, until the Bank notifies the Borrower that it no longer
wishes to require the payment of the additional interest under this
paragraph, and all such additional interest shall be payable on the Interest
Payment Date with respect thereto.

        If an Event of Default (as defined in the Letter Agreement) occurs
and is not cured within the time, if any, provided for by the Letter
Agreement, the Bank may exercise any one or more of the rights and remedies
granted by the Letter Agreement or any document contemplated thereby or given
to a secured party under applicable law, including without limit the right to
accelerate this Note and any other Indebtedness (as defined in the Letter
Agreement), and may set off against the principal of and interest on this
Note or against any other Indebtedness (i) any amount owing by the Bank to
the undersigned, (ii) any property of the undersigned at any time in the
possession of the Bank or any affiliate of the Bank and (iii) any amount in
any deposit or other account (including without limit an account evidenced by
a certificate of deposit) of the undersigned with the Bank or any affiliate
of the Bank.

        In the event that and so long as any Event of Default shall have
occurred and be continuing, the indebtedness outstanding under this Note
shall bear interest at the Overdue Rate.

        The Undersigned and all accommodation parties, guarantors and
indorsers (i) waive presentment, demand, protest and notice of dishonor, (ii)
agree that no extension or indulgence to the undersigned or release or
non-enforcement of any security, whether with or without notice, shall affect
the obligations of any accommodation party, guarantor or indorser, and (iii)
agree to reimburse the holder of this Note for any and all costs and expenses
incurred in collecting or attempting to collect any and all principal and
interest under this Note (including, but not limited to, court costs and
reasonable attorney fees, whether in-house or outside counsel is used and
whether such costs and expenses are incurred in formal or informal collection
actions, federal bankruptcy proceedings, appellate proceedings, probate
proceedings, or otherwise). This Note shall be governed by and construed in

To our
Stockholders,
Employees
and Friends:

The 1998 fiscal year was another record-breaking year for sales and earnings
for Neogen. The Company can now boast of quarterly revenue increases, as
compared to the prior year, in 28 of the past 30 quarters.

Worldwide food safety concerns are beginning to be addressed through the
implementation of new food safety regulations. Concerns about animal safety
increased as food safety programs began to focus back inside the farm gate.
The consolidation of meat and milk production in the U.S. continued as herd
sizes increased but producer numbers decreased.

Financial Performance Solid

Neogen's total revenues for the year were approximately $18.5 million, a 21%
increase as compared to fiscal year 1997. At the bottom line, we reported
record profits of approximately $2.2 million, or $.35 per share. Last year
the Company reported profits of approximately $1.8 million, or $.32 per
share. The Company can now claim a string of 21 consecutive profitable
quarters from operations.

Balance Sheet Strengthens

At year end, the Company had approximately $10.6 million in cash and
marketable securities. In addition, Neogen has bank lines of credit totaling
$10 million, with nothing borrowed against these lines. Stockholders' equity
grew to approximately $23.6 million as compared to $21 million at the
beginning of the year.

New Markets Grow

Neogen focuses its marketing strategy on distinct market segments. The
Company's sales into most of these segments grew during the past year. Our
diagnostic sales to the meat and poultry industry jumped by 93% in fiscal '98
on the heels of a 100% increase in the prior year. Diagnostic sales to the
fruit and vegetable industry were up approximately 80% for the year, and the
fledgling seafood marketing effort began to build momentum.

International sales of food diagnostic products were higher than the prior
year, in spite of weakened currency valuations as compared to the U.S. dollar
in numerous Asian and Latin American markets.

Strong performances in most of the Company's food safety diagnostic areas
were overshadowed by a 14% decrease in sales to the grain, nut and spice
industry. This decrease of approximately $650,000 also had a heavy impact on
the company's overall bottom line.

The quality of the grain crop in the U.S., and most major producing
countries, was unusually good during the 1997 growing season. As a result,
there was much less pressure to test for naturally-occurring toxins than in
normal years. During the prior fiscal year, sales to this market increased
40% because of a poor quality wheat crop in some states.

Revenues of Neogen's Lexington, Kentucky, division, which consists primarily
of sales to the professional equine market, doubled in fiscal 1998. Although
these results were aided by two acquisitions during the year, the base
business at the Lexington division also showed good growth.

Revenues at the Company's Ideal Instruments operation recorded a 4% increase
in sales for the year as a result of the new operating strategy announced
last year.

Two New Acquisitions

In July, we acquired the assets of the Triple Crown Company of Fort Pierce,
Florida. This company had a long and valuable reputation in the manufacture
and marketing of pharmaceutical products for the professional equine market.
Since many of their customers were already Neogen customers, we were able to
merge the products into our existing Lexington marketing and manufacturing
operations.

In December, Neogen acquired ImmunoVet operations from Vetoquinol S.A. of
France. This gave Neogen its first U. S. Department of Agriculture-inspected
biologics production facility. We have maintained the inspected facility in
Tampa, Florida, but have merged all other activities with our Lexington
operations.

New Products Introduced

Several new products were introduced during the year -- all of them finding
demand from our current customer base. Early in the year the Company released
a new test for Listeria. The test detects the presence of this bacteria in
food and on surfaces in food processing plants. As one of the four major
foodborne bacterial concerns, this test should continue to bring increased
revenues to the Company.

The Company also introduced three new food safety products that are of
primary interest to the seafood industry. One of these products is a rapid
and inexpensive test for measurement of possible


                                      2


<PAGE>

sulfite residues in shrimp. Neogen's new quantitative test for the detection
of histamine in fish was introduced at mid-year. As the FDA steps up its
regulation of the seafood industry, this test is expected to find widespread
use.

At year end, the Company completed its work on a diagnostic test for the
detection of Vibrio, a bacteria of concern in shellfish and shrimp. The
market debut of this product occurred as Vibrio-contaminated oysters from
Galveston Bay sickened about three hundred people in five states.

During the year, the Company also introduced a test for the detection of
generic E. coli. Revenues from this test are expected to grow as more food
processors use the test as a general indicator of plant sanitation.

Neogen's research and engineering activities also yielded several new
specialty needles at our Ideal Instruments division, as well as new
diagnostic tests for the detection of drugs of abuse in animals.

Neogen has continued to make a significant investment in R & D programs for
new product development. Total R & D spending now equates to approximately 8%
of total revenues. Ten R & D and research projects now underway should result
in several new products in the year ahead.

Operating Expenses Flat

Sales, marketing, general and administrative expenses were approximately the
same percentage of revenues as last year. One of the reasons the expenses
were not reduced was legal costs related to two lawsuits. Though the outcomes
of the lawsuits are not expected to have any material impact on the Company's
operations, the extra legal expenses provided a negative impact to the bottom
line of approximately $.03 per share. Neogen is the plaintiff in both
lawsuits relating to intellectual property. While the outcome of a lawsuit is
never predictable, management believes it should prevail in both.

New Marketing Structure

At the beginning of fiscal year 1999, the Company's 60-person sales and
marketing organization was divided into Food Safety and Animal Safety groups.
We've asked two of our best senior managers to manage these new areas. We
continue to believe that one of the best ways to add value for our
shareholders is to build our industry's strongest sales and marketing
program.

Though separate, there is a definite synergy between the two groups as food
safety moves back inside the farm gate. We believe significant industry
emphasis will be placed on animal safety to make certain that meat and milk
are safe before they leave the farm.

Growth Strategy Focus

Neogen will continue to focus on implementation of its four-pronged approach
to growth in the year ahead. We believe we're poised to take advantage of
market opportunities.

First, we'll grow revenues through increased sales of current products. The
number of meat and poultry plants required to implement the new USDA HACCP
plan will jump from 300 to 3,300 in January, 1999. Implementation of the FDA
mandatory HACCP plan for the seafood industry should intensify. New
regulatory guidelines, which are expected soon for the fruit juice, and fresh
fruit and vegetable industries, should also increase the
demand for testing.

Our second strategy is to continue to introduce products that we can market
to our same customer base. The new products expected to be released this year
also fit this strategy.

Our third growth strategy is to continue to improve distribution in our
international markets. With only 22% of our current sales going to
international customers, there should be opportunity for strong growth in
this area during the new year.

Our fourth strategy is to continue to grow through acquisitions. Cash and
unused bank lines of credit give us in excess of $20 million to pursue this
strategy. Though management is committed to make acquisitions, we will do so
only in areas that are complementary to our existing business, that we know
how to manage, and that can be purchased at the right price.

Neogen believes our 1999 fiscal year will be an exciting one. We're adding
new customers, introducing new products, strengthening our international
distribution, and actively pursuing acquisitions.

Each year at Neogen's Open House for brokers, analysts and shareholders,
Company officials receive numerous questions concerning Neogen's current
operations, and its vision for the future. What follows are a number of those
frequently-asked questions, and the responses of Company officials, for the
benefit of all existing and potential shareholders.

What is Neogen's strategy for growth?

Neogen's goal is to become the dominant developer, manufacturer and marketer
of products dedicated to food and animal safety.

The Company will work aggressively toward that goal utilizing an approach
focused in four areas.

o Sales revenue from existing products will be grown through continued
  expansion of markets and Neogen's improved positioning for competitive gains
  within those markets.

o The Company will introduce new products and sell them to Neogen's existing
  customer base.

o The Company will expand its penetration into the international market,
  which Neogen believes is even bigger than the domestic market.

o Neogen will continue to pursue the acquisition of complementary businesses
  that fit its overall mission.

<PAGE>

Are there marketing
synergies between food safety and animal safety?

Neogen views food and animal safety as an unbroken continuum. Placing safe
meat on a dinner plate depends on safe handling practices by the consumer,
processor and animal producer; getting safe food animals to the processor
depends on prudent veterinary practices and contamination-free animal feed;
safe animal feed depends on effective monitoring and testing protocols.
Clearly, ensuring that food on a plate is as safe as possible requires the
food industry to look back inside the farm gate.

Will food safety continue to be a concern?

Changing lifestyles and a globalization of the food supply has led to
dramatic changes in how food is processed and prepared. Ready-to-eat and
microwave-warmed, but not cooked, foods are replacing in-home prepared and
cooked foods. Modern shipping allows for foodstuffs to be shipped from and to
all points of the globe. One infected worker can now contaminate food
destined for thousands of consumers across a wide geographic area. Add to the
equation the emergence of new pathogens, and the potential for foodborne
illness ever grows.

How do Neogen's rapid tests fit into the issue of food safety?

Neogen's rapid and accurate test kits are more critical than ever. When
lettuce-borne E. coli from California can sicken 61 people in Illinois,
Connecticut and New York (and kill a 3-year-old), the need for quick,
accurate tests is tragically evident. Foodborne pathogens must now be rapidly
identified and isolated before they can enter the mass distribution system.

Just how big is the food safety problem?

Estimates of foodborne illness vary greatly among experts because of the
large, unknown number of cases that are unreported and not treated by the
medical community. One of the most respected, and cited, organizations
concerned with food safety is the Council for Agricultural Science and
Technology. It estimates foodborne illnesses in the U.S. alone at up to 33
million a year, and deaths as a result of foodborne-related illnesses at
about 9,000 per year in the U.S.

The FDA estimates 48,000 people in the U.S. get sick each year by drinking
contaminated fruit juices.

<PAGE>
How big is the food safety diagnostic test market?

Independent surveys indicate the market should exceed $500 million annually
within the next few years. Based on Neogen's estimates, the Company believes
it has in excess of 80,000 potential customers.

How does Neogen market its food safety products?

Neogen believes the best way to reach markets and build market share is to
build customer "intimacy". Our objective is to develop strong relationships
with existing and potential customers. Furthermore, Neogen sales personnel
are expected to develop expertise in our customers' businesses. By doing so,
we become indispensable to our customers and put Neogen in a much better
position to help solve our customers' problems.

What are Neogen's food safety markets?

Neogen's Food Safety customer base is divided into eight segments: Feed &
Agriculture; Meat, Poultry & Egg; Grain, Nut & Spice; Fruit & Vegetable;
Laboratories; Food Service; Seafood; and International.

What food safety solutions does Neogen provide for these markets?

Neogen provides rapid, accurate screening tests to these markets for
naturally-occurring toxins such as aflatoxin, vomitoxin and histamine;
foodborne bacteria such as E. coli O157:H7 and Salmonella; food allergens
such as peanut components; and general sanitation testing needs. The wide
range of Neogen testing products provides food producers and processors with
an easy, one-stop shopping opportunity.

How are the new
government regulations likely to impact Neogen's sales to the meat and
poultry industry?

The phasing-in of the USDA's Hazard Analysis Critical Control Point (HACCP)
Final Rule in the past year meant 312 of the nation's largest meat and
poultry processing plants were required to implement new regulations which
requires some testing. Within the next two years, about 6,000 additional, mid
size and smaller meat and poultry processors will be required to meet the
HACCP regulations.

Will regulations affect other food industries served by Neogen?

The seafood, and fruit and vegetable industries are also responding to
increasing governmental action. New HACCP regulations, in place since
December, will likely require seafood processors to test for the presence of
sulfites in shrimp and histamine in some fish species -- tests now available
from Neogen.

Fruit and vegetable producers are also anticipating issuance of FDA
guidelines. One FDA proposal would require fruit and vegetable juice
processors to gradually implement their own antibacterial HACCP plans. That
proposal is in response to a FDA estimate of 48,000 people being sickened
yearly by drinking untreated juices contaminated by such bacteria as
Salmonella and E. coli.

Won't the development of such technologies as irradiation and ozone treatment
render Neogen's bacterial tests obsolete?

The opposite should happen. Companies that install expensive equipment to
kill bacteria will still need a rapid, easy test to ensure the equipment is
working properly. Also, companies that don't test now will have a stronger
incentive to do so if technology exists to kill any bacteria that may be
present.

What new products has or will Neogen develop for the food safety markets?

In the past fiscal year, Neogen released its test for Listeria; a rapid test
to detect generic E. coli and total coliforms; a test to detect sulfites in
shrimp; and a quantitative histamine test.

Recently, Neogen released a test to detect Vibrio parahaemolyticus. This
bacteria sickened more than 300 people in a summer 1998 outbreak. V.
parahaemolyticus is responsible for the majority of foodborne gastroenteritis
where the consumption of fish products contributes significantly to the diet,
such as in the Far East.

Also released was a rapid test to detect peanut components in products not
labeled for peanuts. The peanut allergen product is seen as a major step to
protect those sensitive to the allergen, estimated at 1.3 million in the U.S.
alone. Neogen is also pursuing the development of tests for other allergens
of widespread concern, such as eggs and milk.

Another new Neogen food safety product detects Salmonella enteritidis,
primarily an egg-borne bacteria. S. enteritidis is now the leading cause of
gastroenteritis in the U. S.

for Vibrio test kits help ensure the safety of shrimp.

How does Neogen define the term "animal safety"?

The term refers to the safety of food animals destined to enter the food
supply while they remain on farms and ranches, as well as products and
services for companion animals including the professional equine market.

What products does Neogen have that are dedicated to animal safety?

Neogen is the largest producer of diagnostic kits for detection of drugs in
animals. Neogen's test for the steroid clenbuterol, for example, can detect
the unscrupulous use of the steroid to bulk up the animal before it can enter
the food supply, and endanger human health.

Neogen's Ideal Instruments subsidiary provides precise veterinary drug
delivery instruments to help minimize drug residues that might otherwise find
their way into meat and milk supplies.

Neogen also markets a complete line of diagnostic and premium health care
products for the professional equine market. Included in these products are
nearly 70 test kits to detect drugs of abuse in horses; a vaccine for Type B
botulism that poses a deadly threat to horses; a line of health care products
for the professional equine practitioner and a group of topical horse
products.

Were the acquisitions Neogen made during the past fiscal
year related to animal safety?

Neogen made two strong acquisitions that have expanded the Company's product
offerings to existing animal safety customers. Neogen bought Triple Crown
Pharmaceuticals, and its equine veterinarian product line, and certain assets
of Vetoquinol U.S.A., Inc. The principal product involved in the Vetoquinol
purchase was EqStim(R), a biologic used by equine veterinarians to stimulate
a horse's immune system.

Both of these acquisitions have been merged into Neogen's existing operations
in Lexington. More importantly, they started contributing positive sales and
profits immediately.

How does Neogen plan to grow its animal safety presence in the next year?

Like food safety, Neogen has organized its animal safety sales and marketing
according to specific, definable market segments. Our goal is to achieve more
sales to existing animal safety customers, and to build a firm foundation for
rapid future growth in existing markets.

What are Neogen's animal safety markets?

They are: laboratories that use diagnostic tests to detect drugs of abuse in
animals; veterinarians; veterinary supply distributors; over-the-counter
distributors; OEM and specialty product distributors; and international
distributors.

Can Neogen expand the market for veterinary instruments?

Neogen is overcoming the cyclical sales of veterinary instruments by finding
new, related markets for its manufacturing capability. For example, specialty
needles manufactured by Neogen are used to deliver marinades, seasonings and
curing preparations for meat-related industries.

Needles from Ideal Instruments are also being used in a unique application to
vaccinate chicks before they hatch. The practice results in less trauma to
the chicks, which leads to lower mortality rates.

How large are the markets for animal safety?

Management believes the combined markets for animal safety products is in
excess of $1 billion dollars and is growing. The Company estimates there are
in excess of two million customers for these products.

Neogen's primary focus is on the food animal and professional equine portion
of this market.

Can animal safety have an influence on food safety?

Reducing stress on food animals and improving the methods of administering
vaccines and drugs has a big effect on the safety of meat and milk. Animals
under stress have a greater tendency to harbor bacterial infections that will
survive to become foodborne bacteria. Poor quality veterinary instruments
give rise to hidden abscesses in muscles and broken needles left in hams and
roasts.

[graphic omitted]
The development of new markets for its syringes and needles has kept Neogen's
subsidiary, Ideal Instruments -- a 68-year-old company -- growing.

Management's Discussion and Analysis of Financial Condition and
Results of Operations

The information in this Management's Discussion and Analysis of Financial
Condition and Results of Operations contains both historical financial
information and forward-looking statements. Neogen does not provide forecasts
of future financial performance. While management is optimistic about the
Company's long-term prospects, historical financial information may not be
indicative of future financial performance.

Forward-looking statements included herein involve certain risks and
uncertainties. Various factors, including competition, recruitment of and
dependence on key employees, impact of weather on agriculture and food
production, identification and integration of acquisitions, research and
development risks, patent and trade secret protection, government regulation
and other risks detailed from time to time in the Company's reports on file
at the Securities and Exchange Commission may cause actual results to differ
materially from those contained in the forward-looking statements.

                         =======      ==      =======
</TABLE> 

The strong growth in diagnostic product sales was due to several factors. The
acquisitions of Vetoquinol U.S.A., Inc., effective December 30, 1997 and
Triple Crown, effective July 1, 1997 accounted for $2,499,000 in increased
sales. Greater demand for test kits and other products sold to the
professional equine market contributed $538,000 in higher sales while sales
of test kits and reagents for pharmacologics were up $145,000. Diagnostic
test kits sold to the meat and poultry market for the detection of
microorganisms such as E. coli 0157:H7 and Salmonella increased $644,000, or
93%, in 1998 compared to 1997.

Offsetting these increases in diagnostic product sales was a $725,000 or 22%
decline in sales of test kits used for the detection of vomitoxin. Sales of
diagnostic tests for the detection of mycotoxins, including vomitoxin, are
influenced by the uncertainty of weather which impacts growing conditions for
grains, nuts and spices. Management discussed its belief that sales of
vomitoxin test kits would likely decline in the current fiscal year in the
Company's 10-KSB for the year ended May 31, 1997.

The increase in veterinary instrument sales was primarily the result of sales
to a new customer of specialty syringes and needles used to inject marinades
and spices into various red and white meats.

Cost of Goods Sold      $7,960     28%     $6,201
</TABLE>

Costs of goods sold increased $1,759,000 in fiscal year 1998, mostly as a
result of the overall increase in product sales. In addition, raw material
expense increased substantially due to a change in sales mix. Sales of
products sold to the professional equine market, which carry a higher
material cost, increased significantly while sales of diagnostic test kits to
detect vomitoxin, which have a much lower material cost, declined. Management
expects raw material cost to continue to run higher, both in dollars and as a
percent of sales, in the fiscal year ending May 31, 1999.

Research and Development      1,425       8%     1,320
</TABLE>

The increase in sales and marketing expense for the year is primarily due to
higher costs, including the acquisitions of Triple Crown and Vetoquinol,
U.S.A., Inc., associated with marketing products to the professional equine
market. Salaries, fringe, recruiting, relocation, commissions, royalties,
travel, advertising and promotions all showed increases compared to the prior
year, which in total amounted to $583,000.

The majority of the increase in general and administrative expense in fiscal
1998 is the result of higher cost in two categories. Consulting expense was
$178,000 higher due primarily to contract services associated with a new
computer installation, increased consulting pertaining to manufacturing and
approvals for professional equine products, and also because of management
consulting pertaining to the Company's Ampcor Diagnostic, Inc. subsidiary.

In addition, legal and professional fees increased $202,000 compared to the
prior year. Management believes that the Company is not involved in any
material adverse legal proceedings. However, Neogen is a party in several
lawsuits as discussed in Item 3. Legal Proceedings in the Company's Form
10-KSB for the year ended May 31, 1998. Management intends to vigorously
pursue this litigation and cannot predict the outcome of these lawsuits.
Furthermore, the Company has no way to predict the level of expenses that may
be incurred in fiscal year 1999 in pursuing this litigation.

</TABLE>

Other income was $333,000 higher than last year. In October 1996, the Company
completed a public offering of common stock. A portion of the proceeds was
used to pay down short-term bank borrowings, resulting in lower interest
expense. The remaining proceeds were invested in short-term marketable
securities, which have resulted in higher interest income. In addition, the
Company's share of royalties, paid to an affiliated partnership, increased
significantly compared to the prior year.

Net Income Per Share Diluted       $    .35                 $  .32
</TABLE>

The increase in net income and net income per share is the direct result of
the increase in sales of diagnostic products, including acquisitions, along
with the increase in other income.

Neogen's effective federal tax rate has been insignificant because the
Company has had net operating loss carryforwards available to offset taxable
income. Upon utilization of its remaining net operating loss carryforwards,
Neogen's effective federal tax rate will increase significantly.

Financial Condition and Liquidity

At May 31, 1998 the Company had $10,589,000 in cash and marketable
securities, working capital of $17,192,00 and stockholders' equity of
$23,609,000. In addition, the Company has bank lines of credit totaling
$10,000,000 with nothing borrowed against these lines as of May 31, 1998.
Cash and marketable securities decreased $2,455,000 during fiscal year 1998
as a result of the acquisitions of certain assets of W.J. Bartus, Inc. and
Vetoquinol U.S.A., Inc..

Effective July 1, 1997 the Company acquired substantially all of the assets
of Triple Crown Pharmaceuticals, a division of W.J. Bartus, Inc. of Ft.
Pierce, Florida. The initial purchase price consisted of a cash payment of
approximately $1,400,000 paid in July 1997. A second and final cash payment
of up to $500,000 will be paid in fiscal year 1999 provided the seller meets
certain conditions of the asset purchase agreement. Effective December 30,
1997 the Company acquired certain assets of Vetoquinol, U.S.A., Inc. located
in Tampa, Florida. The initial purchase price consisted of a cash payment of
approximately $2,035,000 paid at closing and a second cash payment of
approximately $153,000 paid in April 1998.

Accounts receivable were higher at May 31, 1998 than May 31, 1997 partially
as a result of the aforementioned acquisitions and partially because of
higher sales volume during the last quarter of fiscal 1998 compared to the
last quarter of fiscal 1997. Inventories were higher at May 31, 1998 as a
result of the acquisitions, to support increases in sales of professional
equine products and in anticipation of future increases in sales volume.

The increase in goodwill and other non-current assets at May 31, 1998
compared to May 31, 1997 was due to the previously discussed acquisitions.
Accounts payable decreased $264,000 partially due to lower trade payables for
inventory at May 31, 1998 and also due to the timing of year-end cut-offs and
scheduled payment dates for trade payables.

The Company did not borrow any additional funds during fiscal year 1998 and
made scheduled payments on long-term debt totaling $56,000. Neogen expended
approximately $646,000 during 1998 for additions to property, equipment and
other assets. At May 31, 1998 the Company had no material commitments for
capital expenditures. Inflation and changing prices are not expected to have
a material effect on the Company's operations.

Neogen has been profitable for twenty of its last twenty-one quarters and has
generated positive cash flows from operations during this period. Management
believes that the Company's existing cash and marketable securities at May
31, 1998, along with its available bank lines of credit and cash expected to
be generated from future operations, will be sufficient to fund activities
for the foreseeable future. However, existing cash and marketable securities
may not be sufficient to meet the Company's cash requirements to
commercialize products currently under development or its plans to acquire
additional technology and products that fit within the Company's mission
statement. Accordingly, the Company may be required to issue equity
securities or enter into other financing arrangements for a portion of the
Company's future capital needs.

Year 2000

The company believes that its financial and manufacturing systems are year
2000 compliant with the exception of the financial software used at its Ideal
Instruments subsidiary. The Company plans on implementing software changes by
November 30, 1998 at the Ideal Instruments subsidiary to ensure year 2000
compliance. The Company does not expect implementation of these changes to
have a material impact on its results of operation. The Company's operations
with respect to the year 2000 may also be affected by other entities with
whom it transacts business. The Company is currently unable to determine the
potential impact, if any, that could result from such entities' failure to
adequately address this issue.

Neogen Corporation and Subsidiaries

Notes to Consolidated Financial Statements


1. Summary of Accounting Policies

Nature of Operations

Neogen Corporation and subsidiaries (the Company) develop, manufacture, and
sell a diverse line of products dedicated to food and animal safety. The
Company's products are currently used for animal health applications, food
safety testing and in medical research.

Basis of Consolidation

The consolidated financial statements include the accounts of Neogen
Corporation, Ideal Instruments, Inc. (Ideal), AMPCOR Diagnostics, Inc.
(AMPCOR) and several majority owned companies which are general partners for
research limited partnerships. The investments in partnerships are not
significant to the consolidated financial statements.

All significant intercompany accounts and transactions have been eliminated
in consolidation.

Use of Estimates

In preparing financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and
assumptions that affect (1) the reported amounts of assets and liabilities
and the disclosure of contingent assets and liabilities as of the date of the
financial statements, and (2) revenues and expenses during the reporting
period. Actual results could differ from these estimates.

Risks and Uncertainties

Diagnostic products, specifically test kits for the detection of vomitoxin,
contribute a significant portion of the Company's revenues and profits. The
Company expects that its ability to maintain or expand its current levels of
revenues and profits in the future will depend on
various factors, including the impact of weather on
agriculture and food production.

Concentrations of Credit Risk

Financial instruments which potentially subject the Company to concentrations
of credit risk consist principally of accounts receivable. The Company
attempts to minimize credit risk by reviewing all customers' credit history
before extending credit and by monitoring customers' credit exposure on a
continuing basis. The Company establishes an allowance for possible losses on
accounts receivable based upon factors surrounding the credit risk of
specific customers, historical trends and other information.

Fair Values of Financial Instruments

The carrying amounts of accounts receivable, accounts payable, and accrued
expenses approximate fair value because of the short maturity of these items.

The carrying amounts of the notes payable and long-term debt issued pursuant
to the Company's bank credit agreements approximate fair value because the
interest rates on these instruments change with market rates.

Marketable Securities

All marketable securities are classified as available-for-sale and are
available to support current operations or to take advantage of other
investment opportunities. These securities are stated at estimated fair
market value. The cost of securities sold is based on the specific
identification method and interest earned is included in other income.

Inventories

Inventories are stated at the lower of cost, determined on the first-in,
first-out method, or market. The components of inventories are as follows:

                     ==========   ==========

</TABLE>


Property and Equipment

Property and equipment is stated at cost. Expenditures for major improvements
are capitalized while repairs and maintenance are charged to expense.
Depreciation is provided on the straight-line method over the estimated
useful lives of the respective assets, generally twenty to thirty-one years
for buildings and improvements, and three to ten years for furniture,
machinery and equipment. Depreciation expense was $469,324 and $389,582 in
1998 and 1997, respectively.

Intangible Assets

Goodwill represents the excess of acquisition costs over the estimated fair
value of net assets acquired. Goodwill is amortized on a straight-line basis
over periods ranging from fifteen to twenty-five years. The Company reviews
goodwill for impairment based upon undiscounted cash flows from operations
before interest over the remaining lives of the goodwill. If necessary,
impairment will be measured based on the difference between discounted future
cash flows and the net book value of the related goodwill.

Neogen Corporation and Subsidiaries

Notes to Consolidated Financial Statements


Other intangible assets, consisting primarily of covenants not to compete,
licenses and patents, are recorded at fair value at the date of acquisition.
These intangible assets are amortized on a straight-line basis over periods
ranging from five to seventeen years.

Long-lived Assets

The Company reviews the carrying values of its long-lived assets for possible
impairment whenever events or changes in circumstance indicate that the
carrying amount of the assets may not be recoverable. The Company evaluates
whether impairment exists on the basis of undiscounted future cash flows from
operations before interest for the remaining useful life of the assets. Any
long-lived assets held for disposal are reported at the lower of these
carrying amounts or fair value less costs to sell.

Revenue Recognition

The Company recognizes product sales at the time of shipment.

Earnings Per Share

In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 128, "Earnings per Share". SFAS
No. 128 replaced the previously reported primary and fully diluted earnings
per share with basic and diluted earnings per share. Unlike primary earnings
per share, basic earnings per share excludes any dilutive effects of options,
warrants, and convertible securities. Diluted earnings per share is very
similar to the previously reported fully diluted earnings per share. All
earnings per share amounts for all periods have been presented, and where
necessary, restated to conform to the SFAS No. 128 requirements. The
following table presents the earnings per share calculations:

Options to purchase 33,400 and 128,500 shares of common stock at prices
ranging from $11.31 to $13.25 and $7.50 to $9.25 in 1998 and 1997
respectively, were outstanding, but were not included in the computation of
diluted earnings per share because the option's exercise price was greater
than the average market price of the common shares.

Recent Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income", and SFAS No. 131 "Disclosures about
Segments of an Enterprise and Related Information." These statements are
effective for financial periods beginning after December 15, 1997 and require
comparative information for earlier years to be restated. Management has not
determined the impact, if any, these statements may have on future financial
statement disclosures.

Statement of Position (SOP) 98-5, "Reporting on the Cost of Start-Up
Activities", was issued in April 1998 and SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities", was issued in June 1998.
These statements are effective in fiscal 2000 and are not
expected to have a material impact on the
consolidated financial statements.

2. Marketable Securities

The Company currently invests in only high quality, short-term investments
with maturity dates of less than one year, which are classified as
available-for-sale. As such, there were no significant differences between
amortized cost and estimated fair market value at May 31, 1998 and 1997.
Additionally, since investments are short-term and are generally allowed to
mature, realized gains and losses for both years have been minimal. The
following table presents the estimated fair value breakdown of investment by
category:

Notes to Consolidated Financial Statements

3. Acquisitions

Effective July 1, 1997, Neogen acquired certain assets of Triple Crown, a
division of W.J. Bartus, Inc. of Fort Pierce, Florida. The acquisition was
accounted for by the purchase method and all acquired assets, consisting of
inventory, fixed assets and 20 related products were moved to the Company's
Lexington, Kentucky division.

The initial purchase price consisted of a cash payment of approximately
$1,400,000, resulting in goodwill of approximately $900,000. Additional
consideration in the amount of approximately $500,000 is expected to be paid
in fiscal 1999 based upon the seller meeting certain conditions of the asset
purchase agreement.

Effective December 30, 1997, Neogen acquired certain assets of Vetoquinol,
U.S.A., Inc. located in Tampa, Florida. The acquisition was accounted for by
the purchase method. Neogen plans to continue to operate the production
facility in Tampa and has relocated all sales and administrative functions to
the Company's Lexington, Kentucky facility.

The purchase price consisted of initial consideration of approximately
$2,035,000 in cash paid at closing. A second cash payment of approximately
$153,000 was paid in April 1998. The cumulative purchase price resulted in
goodwill of approximately $1,250,000. Additional consideration not to exceed
$200,000 may be paid based upon operating performance for the twelve month
periods ending December 31, 1998 and 1999.

Pro forma results of operations are not presented as the effect of the
acquisitions was not material to the consolidated results of operations of
the Company for the year ended May 31, 1998.

by substantially all assets of the Company and its subsidiaries.

In addition, the Company maintains an unsecured acquisition line-of-credit in

The term note is payable in sixty monthly installments of $4,056 plus
interest at the prime rate less 0.50% and is collateralized by substantially
all the assets of Neogen and AMPCOR.

The terms of certain financing agreements contain, among other provisions,
the requirements to meet certain financial ratios and levels of working
capital and tangible net worth, and restrict the payment of dividends.

6. Stock Options and Stock Warrants

The Company maintains Stock Option Plans (the Plans) under which qualified
and non-qualified options to purchase shares of common stock may be granted
to eligible directors, members of the Scientific Review Council, officers, or
employees of the Company at an exercise price of not less than the fair
market value of the stock on the date of grant. The number of shares
authorized for issuance under the Plans is 1,459,375. At May 31, 1998,
options have been granted with three to five year vesting schedules and
option terms of five to ten years. A total of 366,600 shares were available
for future grants under the Plans.

The Company applies Accounting Principles Board Opinion No. 25 in accounting
for its stock option plans. Accordingly, no compensation

Deferred income taxes reflect the tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial
reporting purposes and the amounts used for income tax purposes. Significant
components of the Company's deferred tax liabilities and assets as of May 31,
1998 and 1997 are as follows:

SFAS No. 109 requires that a valuation allowance be recorded against tax
assets which are not likely to be realized. The Company's carryforwards
expire at specific future dates. Due to the uncertain nature of their
ultimate realization based upon past performance and the difficulty
predicting future results, the Company has established a full valuation
allowance against these carryforward benefits and is recognizing the benefits
only as reassessment demonstrates they are realizable. The need for this
valuation allowance is subject to periodic review. If the allowance is
reduced, the tax benefits of the carryforwards will be recorded in future
operations as a reduction of the Company's income tax expense.

The reconciliation of income taxes computed at the U.S. federal statutory tax
rates to income tax expense for the years ended May 31, 1998 and 1997 is as
follows:
